What makes a city 'breastfeeding-friendly'? A scoping review of indicators of a breastfeeding-friendly city. MATERNAL & CHILD NUTRITION 2024; 20:e13608. [PMID: 38100143 PMCID: PMC10981478 DOI: 10.1111/mcn.13608] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 11/20/2023] [Accepted: 11/28/2023] [Indexed: 01/19/2024]
Abstract
A breastfeeding-friendly city is one where there is an enabling environment to support breastfeeding throughout the first 2 years or more of a child's life. Indicators of a breastfeeding-friendly city have yet to be identified. What are the indicators or criteria used to define breastfeeding friendliness in a geographic area such as a city and the settings within, which we have classified as community, healthcare and workplace? Three major databases and grey literature were searched. Records were screened to identify publications describing criteria such as indicators or descriptions of a breastfeeding-friendly setting, defined as 'criteria-sets'. These criteria-sets were then categorized and summarized by settings. The search up to 2 September 2021 found 119 criteria-sets from a range of settings: geographic locations (n = 33), community entities (n = 24), healthcare facilities (n = 28), workplaces (n = 28) and others (n = 6). Overall, 15 community, 22 healthcare and 9 workplace related criteria were extracted from the criteria-sets. Criteria that were consistently present in all settings were policy, training & education, skilled breastfeeding support and physical infrastructure. Some criteria-sets of geographic locations contained criteria only from a single setting (e.g., the presence of breastfeeding-friendly cafes). Criteria-sets were present for all settings as defined in this review, but few were actual indicators. Specifically, there were no existing indicators of a breastfeeding-friendly city. Several common components of the criteria-sets were identified, and these could be used in developing indicators of a breastfeeding-friendly city. Future studies should determine which of these are important and how each can be measured.

Exploring factors influencing the uptake of kangaroo mother care: key informant interviews with parents. BMC Pregnancy Childbirth 2023; 23:706. [PMID: 37789260 PMCID: PMC10548712 DOI: 10.1186/s12884-023-06021-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2023] [Accepted: 09/22/2023] [Indexed: 10/05/2023] Open
Abstract
BACKGROUND The updated World Health Organization (WHO) guideline recommends immediate kangaroo mother care (KMC) for all infants, particularly those born preterm. However, its uptake and sustainability have been unsatisfactory. Therefore, we aimed to gain deeper insight into factors influencing the uptake of KMC practice in our setting, and thereby identify possible solutions for the development of relevant interventions to improve its adoption and make KMC a routine practice for all infants. METHODS Using the Triandis model of social behaviour as our framework, we conducted key informant interviews with parents and healthcare providers. Trained interviewers conducted interviews with nine parents, recruited via purposive sampling. These parents were parents of preterm infants who had been introduced to KMC. Data was transcribed and analysed based on Triandis' Theory of Interpersonal Behaviour. This paper only reports the results of the parent interviews. RESULTS Major findings were how positive feelings like warmth and contentment, the sense of parenthood with KMC, the benefits of KMC for their infant and parents being enablers for KMC uptake. Conversely, the lack of KMC awareness, the initial negative feelings such as fear, uncertainty and embarrassment, the prioritization of time for milk expression, overcrowding in the ward, lack of space and privacy, limited visiting hours, lack of support and poor communication resulting in misapprehension about KMC were major barriers. CONCLUSION A deeper understanding of the factors influencing the uptake of KMC using the Triandis behavioural model provided a way forward to help improve its uptake and sustainability in our settings. TRIAL REGISTRATION This study was registered with the National Medical Research Registry (NMRR-17-2984-39191).

Abstract
BACKGROUND Apnoea of prematurity (AoP) is defined as a pause in breathing for 20 seconds or longer, or for less than 20 seconds when accompanied by bradycardia and hypoxaemia, in a preterm infant. An association between the severity of apnoea and neurodevelopmental delay has been reported. Continuous positive airway pressure (CPAP) is a form of non-invasive ventilatory assistance that has been shown to be relatively safe and effective in preventing and treating respiratory distress among preterm infants. It is less clear whether CPAP treatment is safe and effective in the prevention and treatment of AoP. OBJECTIVES 1. To assess the effects of CPAP on AoP in preterm infants (this may be compared to supportive care or mechanical ventilation). 2. To assess the effects of different CPAP delivery systems on AoP in preterm infants. SEARCH METHODS Searches were conducted in September 2022 in the following databases: Cochrane Library, MEDLINE, Embase, and CINAHL. We also searched clinical trial registries and the reference lists of studies selected for inclusion. SELECTION CRITERIA We included all randomised and quasi-randomised controlled trials (RCTs) in which researchers determined that CPAP was necessary for AoP in preterm infants (born before 37 weeks). Cross-over studies were also included, provided sufficient data were available for analysis. DATA COLLECTION AND ANALYSIS We used the standard methods of Cochrane and Cochrane Neonatal, including independent assessment of risk of bias and extraction of data by at least two review authors. Discrepancies were resolved by involvement of a third author. We used the GRADE approach to assess the certainty of evidence for the following outcomes: 1) failed CPAP; 2) apnoea; 3) adverse effects of CPAP. MAIN RESULTS We included four single-centre trials conducted in Malaysia, Spain, Germany, and North America, involving 138 infants with a mean/median gestation of 26 to 28 weeks. Two studies were parallel-group RCTs and two were cross-over trials. None of the studies compared CPAP with supportive care. All trials compared one form of CPAP with another. Two compared a variable flow device with ventilator CPAP, one compared two different variable flow devices, and one compared a variable flow device with bubble CPAP. Interventions were administered for periods ranging between six and 48 hours, with pressures between 4 and 6 cm H2O. We assessed all trials as having a high risk of bias for blinding of participants and personnel, and two studies for blinding of outcome assessors. We found a high risk of a carry-over effect in two studies where the washout period was not adequately described, and a high risk of bias in a study that appeared to use an analysis method not generally accepted for cross-over studies. Comparison 1. CPAP and supportive care compared to supportive care alone We did not identify any study for inclusion in this comparison. Comparison 2. CPAP delivered by different types of devices 2a. Variable flow compared to ventilator CPAP Two studies were included in this comparison. We are very uncertain whether there is any difference in the incidence of failed CPAP, defined as the need for mechanical ventilation (risk ratio (RR) 0.16, 95% confidence interval (CI) 0.01 to 2.90; 1 study, 26 participants; very low-certainty). We are very uncertain whether there is any difference in the frequency of apnoea events (mean difference (MD) per four-hour interval -0.10, 95% CI -1.30 to 1.10; 1 study, 26 participants; very low-certainty). We are uncertain whether there is any difference in adverse events. Neurodevelopmental outcomes were not reported. 2b. Variable flow compared to bubble CPAP We included one study in this comparison, but it did not report our pre-specified outcomes. 2c. Infant Flow variable flow CPAP compared to Medijet variable flow CPAP We are very uncertain whether there is any difference in the incidence of failed CPAP (RR 2.62, 95% CI 0.91 to 7.53; 1 study, 80 participants; very low-certainty). The frequency of apnoea was not reported, and we do not know whether there is any difference in adverse events. Neurodevelopmental outcomes were not reported. Comparison 3. CPAP compared to mechanical ventilation We did not identify any studies for inclusion in this comparison. AUTHORS' CONCLUSIONS Due to the limited available evidence, we are very uncertain whether any CPAP device is more effective than other forms of supportive care, other CPAP devices, or mechanical ventilation for the prevention and treatment of AoP. The devices used in these studies included two types of variable flow CPAP device: bubble CPAP and ventilator CPAP. For each comparison, data were only available from a single study. There are theoretical reasons why these devices might have different effects on AoP, therefore further trials are indicated.

Foetal haemoglobin inducers for reducing blood transfusion in non-transfusion-dependent beta-thalassaemias. Cochrane Database Syst Rev 2023; 1:CD013767. [PMID: 36637054 PMCID: PMC9837847 DOI: 10.1002/14651858.cd013767.pub2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/14/2023]
Abstract
BACKGROUND Non-transfusion-dependent β-thalassaemia (NTDβT) is a subset of inherited haemoglobin disorders characterised by reduced production of the β-globin chain of haemoglobin leading to anaemia of varying severity. Although blood transfusion is not a necessity for survival, it may be required to prevent complications of chronic anaemia, such as impaired growth and hypercoagulability. People with NTDβT also experience iron overload due to increased iron absorption from food sources which becomes more pronounced in those requiring blood transfusion. People with a higher foetal haemoglobin (HbF) level have been found to require fewer blood transfusions, thus leading to the emergence of treatments that could increase its level. HbF inducers stimulate HbF production without altering any gene structures. Evidence for the possible benefits and harms of these inducers is important for making an informed decision on their use. OBJECTIVES To compare the effectiveness and safety of the following for reducing blood transfusion for people with NTDβT: 1. HbF inducers versus usual care or placebo; 2. single HbF inducer with another HbF inducer, and single dose with another dose; and 3. combination of HbF inducers versus usual care or placebo, or single HbF inducer. SEARCH METHODS We used standard, extensive Cochrane search methods. The latest search date was 21 August 2022. SELECTION CRITERIA We included randomised controlled trials (RCTs) or quasi-RCTs comparing single HbF inducer with placebo or usual care, with another single HbF inducer or with a combination of HbF inducers; or comparing different doses of the same HbF inducer. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. Our primary outcomes were blood transfusion and haemoglobin levels. Our secondary outcomes were HbF levels, the long-term sequelae of NTDβT, quality of life and adverse events. MAIN RESULTS We included seven RCTs involving 291 people with NTDβT, aged two to 49 years, from five countries. We reported 10 comparisons using eight different HbF inducers (four pharmacological and four natural): three RCTs compared a single HbF inducer to placebo and seven to another HbF inducer. The duration of the intervention lasted from 56 days to six months. Most studies did not adequately report the randomisation procedures or whether and how blinding was achieved. HbF inducer against placebo or usual care Three HbF inducers, HQK-1001, Radix Astragali or a 3-in-1 combined natural preparation (CNP), were compared with a placebo. None of the comparisons reported the frequency of blood transfusion. We are uncertain whether Radix Astragali and CNP increase haemoglobin at three months (mean difference (MD) 1.33 g/dL, 95% confidence interval (CI) 0.54 to 2.11; 1 study, 2 interventions, 35 participants; very low-certainty evidence). We are uncertain whether Radix Astragali and CNP have any effect on HbF (MD 12%, 95% CI -0.74% to 24.75%; 1 study, 2 interventions, 35 participants; very low-certainty evidence). Only medians on haemoglobin and HbF levels were reported for HQK-1001. Adverse effects reported for HQK-1001 were nausea, vomiting, dizziness and suprapubic pain. There were no prespecified adverse effects for Radix Astragali and CNP. HbF inducer versus another HbF inducer Four studies compared a single inducer with another over three to six months. Comparisons included hydroxyurea versus resveratrol, hydroxyurea versus thalidomide, hydroxyurea versus decitabine and Radix Astragali versus CNP. No study reported our prespecified outcomes on blood transfusion. Haemoglobin and HbF were reported for the comparison Radix Astragali versus CNP, but we are uncertain whether there were any differences (1 study, 24 participants; low-certainty evidence). Different doses of the same HbF inducer Two studies compared two different types of HbF inducers at different doses over two to six months. Comparisons included hydroxyurea 20 mg/kg/day versus 10 mg/kg/day and HQK-1001 10 mg/kg/day, 20 mg/kg/day, 30 mg/kg/day and 40 mg/kg/day. Blood transfusion, as prespecified, was not reported. In one study (61 participants) we are uncertain whether the lower levels of both haemoglobin and HbF at 24 weeks were due to the higher dose of hydroxyurea (haemoglobin: MD -2.39 g/dL, 95% CI -2.80 to -1.98; very low-certainty evidence; HbF: MD -10.20%, 95% CI -16.28% to -4.12%; very low-certainty evidence). The study of the four different doses of HQK-1001 did not report results for either haemoglobin or HbF. We are not certain if major adverse effects may be more common with higher hydroxyurea doses (neutropenia: risk ratio (RR) 9.93, 95% CI 1.34 to 73.97; thrombocytopenia: RR 3.68, 95% CI 1.12 to 12.07; very low-certainty evidence). Taking HQK-1001 20 mg/kg/day may result in the fewest adverse effects. A combination of HbF inducers versus a single HbF inducer Two studies compared three combinations of two inducers with a single inducer over six months: hydroxyurea plus resveratrol versus resveratrol or hydroxyurea alone, and hydroxyurea plus l-carnitine versus hydroxyurea alone. Blood transfusion was not reported. Hydroxyurea plus resveratrol may reduce haemoglobin compared with either resveratrol or hydroxyurea alone (MD -0.74 g/dL, 95% CI -1.45 to -0.03; 1 study, 54 participants; low-certainty evidence). We are not certain whether the gastrointestinal disturbances, headache and malaise more commonly reported with hydroxyurea plus resveratrol than resveratrol alone were due to the interventions. We are uncertain whether hydroxyurea plus l-carnitine compared with hydroxyurea alone may increase mean haemoglobin, and reduce pulmonary hypertension (1 study, 60 participants; very low-certainty evidence). Adverse events were reported but not in the intervention group. None of the comparisons reported the outcome of HbF. AUTHORS' CONCLUSIONS We are uncertain whether any of the eight HbF inducers in this review have a beneficial effect on people with NTDβT. For each of these HbF inducers, we found only one or at the most two small studies. There is no information on whether any of these HbF inducers have an effect on our primary outcome, blood transfusion. For the second primary outcome, haemoglobin, there may be small differences between intervention groups, but these may not be clinically meaningful and are of low- to very low-certainty evidence. Data on adverse effects and optimal doses are limited. Five studies are awaiting classification, but none are ongoing.

Use of Galactagogues in a Multi-Ethnic Community in Southeast Asia: A Descriptive Study. Int J Womens Health 2022; 14:1395-1404. [PMID: 36172202 PMCID: PMC9512541 DOI: 10.2147/ijwh.s366288] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Accepted: 08/15/2022] [Indexed: 12/04/2022] Open
Abstract
Purpose Galactagogues are substances that increase breast-milk production. They can be medication, herbs or food. Use of galactagogues may be different among the major ethnic groups in Malaysia. The primary objective of this cross-sectional study is to determine the prevalence of galactagogues use among breastfeeding mothers in a multi-ethnic community. Patients and Methods Self-administered questionnaires were distributed between November 2016 and January 2017 to mothers attending the health clinics and private hospital paediatric clinics in Penang, Malaysia, whose infants were below 6 months of age. The questionnaire enquired about use of galactagogues, types of galactagogue used, perceived effectiveness and sources of information. It also asked mothers about what they would do to increase milk supply. Results We analyzed 322 out of 530 questionnaires distributed where 76% of mothers reported use of galactagogues; most of which were food-based: dates (66%), oats (58%) and soya bean (56%). Each major ethnic group had a different preference for galactagogues: Malays (dates), Chinese (soya bean) and Indians (oats). Only one mother used pharmacological galactagogues alone. Galactagogues were perceived to be effective by 65% of mothers who used them. Multivariate analysis showed that use of galactagogues was not related to ethnicity, education, work, perception of milk supply or use of formula milk. The most common source of information on galactagogues came from family and friends. Conclusion Use of galactagogues is common in our population, especially food-based ones, and the choice of galactagogues differs by ethnicity. Future studies on efficacy and safety galactagogues should be focused these commonly used ones. There is also a need for qualitative studies to improve our understanding of why they are widely used in this region.

A Participatory, Needs-Based Approach to Breastfeeding Training for Confinement Centres. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:10914. [PMID: 36078639 PMCID: PMC9517788 DOI: 10.3390/ijerph191710914] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Revised: 08/23/2022] [Accepted: 08/23/2022] [Indexed: 06/15/2023]
Abstract
With a focus on traditional practices rather than evidence-based practices, breastfeeding support is sub-optimal in confinement centres (CCs). We used a participatory, needs-based approach to develop a training module for CC staff adopting Kern's six-step approach as our conceptual framework. Of 46 identified CCs, 25 accepted our invitation to a dialogue aimed at establishing relationships and understanding their needs. An interactive training workshop was developed from the dialogue's findings. The workshop, attended by 32 CCs (101 participants), was conducted four times over a four-month period. Questions raised by the participants reflected deficits in understanding breastfeeding concepts and erroneous cultural beliefs. Correct answers rose from 20% pre-test to 51% post-test. Post-workshop feedback showed that participants appreciated the safe environment to ask questions, raise concerns and correct misconceptions. An interview conducted 14 months later showed that while some CCs improved breastfeeding support, others made no change due to conflict between breastfeeding and traditional postnatal practices, which was aggravated by a lack of support due to the COVID-19 pandemic. A participatory approach established a trustful learning environment, helping CCs appreciate the value of learning and adopting new concepts. However, cultural perceptions take time to change, hence continuous training and support are vital for sustained changes.

Abstract
BACKGROUND Cohort studies have suggested that nasal continuous positive airway pressure (CPAP) starting in the immediate postnatal period before the onset of respiratory disease (prophylactic CPAP) may be beneficial in reducing the need for intubation and intermittent positive pressure ventilation (IPPV), and in preventing bronchopulmonary dysplasia (BPD), in preterm or low birth weight infants. OBJECTIVES To determine if prophylactic nasal CPAP (started within the first 15 minutes) or very early nasal CPAP regardless of respiratory status (started within the first hour of life), reduces the use of mechanical ventilation and the incidence of bronchopulmonary dysplasia without any adverse effects in preterm infants. SEARCH METHODS A comprehensive search was run on 6 November 2020 in the Cochrane Central Register of Controlled Trials (CENTRAL via CRS Web) and MEDLINE via Ovid. We also searched the reference lists of retrieved studies. SELECTION CRITERIA We included all randomised controlled trials (RCTs) and quasi-RCTs in preterm infants (under 37 weeks of gestation). We included trials if they compared prophylactic nasal CPAP (started within the first 15 minutes) or very early nasal CPAP (started within the first hour of life) in infants with minimal signs of respiratory distress with 'supportive care', such as supplemental oxygen therapy, standard nasal cannula, or mechanical ventilation. We excluded studies where prophylactic CPAP was compared with CPAP along with co-interventions. DATA COLLECTION AND ANALYSIS We used the standard methods of Cochrane Neonatal, including independent study selection, assessment of trial quality, and extraction of data by two review authors. MAIN RESULTS We included eight trials (seven from the previous version of the review and one new study), recruiting 3201 babies, in the meta-analysis. Four trials, involving 765 babies, compared CPAP with supportive care, and three trials (2364 babies) compared CPAP with mechanical ventilation. One trial (72 babies) compared prophylactic CPAP with very early CPAP. Apart from a lack of blinding of the intervention, we judged seven studies to have a low risk of bias. However, one study had a high risk of selection bias. Prophylactic or very early CPAP compared to supportive care There may be a reduction in failed treatment (risk ratio (RR) 0.6, 95% confidence interval (CI) 0.49 to 0.74; risk difference (RD) -0.16, 95% CI -0.34 to 0.02; 4 studies, 765 infants; very low certainty evidence). CPAP possibly reduces BPD at 36 weeks (RR 0.76, 95% CI 0.51 to 1.14; 3 studies, 683 infants, moderate certainty evidence); there may be little or no difference in death (RR 1.04, 95% CI 0.56 to 1.93; 4 studies, 765 infants; moderate certainty evidence). Prophylactic CPAP may reduce the composite outcome of death or BPD (RR 0.69, 95% CI 0.40 to 1.19; 1 study, 256 infants; low certainty evidence). There may be no difference in pulmonary air leak (pneumothorax) (RR 0.75, 95% CI 0.35 to 1.16; 3 studies, 568 infants; low certainty evidence), or intraventricular haemorrhage (IVH) Grade 3 or 4 (RR 0.96, 95% CI 0.39 to 2.37; 2 studies, 486 infants; moderate certainty evidence). Neurodevelopmental impairment was not reported in any of the studies. Prophylactic or very early CPAP compared to mechanical ventilation There was probably a reduction in the incidence of BPD at 36 weeks (RR 0.89, 95% CI 0.8 to 0.99; RD -0.04, 95% CI -0.08 to 0.00; 3 studies, 2150 infants; moderate certainty evidence); and death or BPD (RR 0.89, 95% CI 0.81 to 0.97; RD -0.05, 95% CI -0.09 to 0.01; 3 studies, 2358 infants; moderate certainty evidence). There was also probably a reduction in the need for mechanical ventilation (failed treatment) (RR 0.49, 95% CI 0.45 to 0.54; RD -0.50, 95% CI -0.54 to -0.45; 2 studies, 1042 infants; moderate certainty evidence). There was probably a reduction in the incidence of death (RR 0.82, 95% CI 0.66 to 1.03; 3 studies, 2358 infants; moderate certainty evidence); pulmonary air leak (pneumothorax) (RR 1.24, 95% CI 0.91 to 1.69; 3 studies, 2357 infants; low certainty evidence); and IVH Grade 3 or 4 (RR 1.09, 95% CI 0.86 to 1.39; 3 studies, 2301 infants; moderate certainty evidence). One study in this comparison reported that there was probably little or no difference between the groups in the incidence of neurodevelopmental impairment at 18 to 22 months (RR 0.91, 95% CI 0.62 to 1.32; 976 infants; moderate certainty evidence). Prophylactic CPAP compared with very early CPAP There was one study in this comparison. We are very uncertain whether there is any difference in the incidence of BPD (RR 0.5, 95% CI 0.05 to 5.27; very low certainty evidence). The combined outcome of death and BPD was not reported, and failed treatment was reported but without data. There may have been little to no effect on death (RR 0.75, 95% CI 0.29 to1.94; 1 study, 72 infants; very low certainty evidence). Intraventricular haemorrhage Grade 3 or 4 and neurodevelopmental outcomes were not reported in this study. Pulmonary air leak (pneumothorax) was reported in this study, but there were no events in either group. AUTHORS' CONCLUSIONS For preterm and very preterm infants, there is insufficient evidence to evaluate prophylactic CPAP compared to oxygen therapy and other supportive care. When compared to mechanical ventilation, prophylactic nasal CPAP in very preterm infants reduces the incidence of BPD, the combined outcome of death and BPD, and mechanical ventilation. There is probably no difference in neurodevelopmental impairment at 18 to 22 months of age. When prophylactic CPAP is compared to early CPAP, we are very uncertain about whether there is any difference between prophylactic and very early CPAP. There is no information about the effect of prophylactic or very early CPAP in late preterm infants. There is one study awaiting classification.

Abstract
BACKGROUND There is presently no certainty about the ideal feeding intervals for preterm infants. Shorter feeding intervals of, for example, two hours, have the theoretical advantage of allowing smaller volumes of milk. This may have the potential to reduce the incidence and severity of gastro-oesophageal reflux. Longer feeding intervals have the theoretical advantage of allowing more gastric emptying between two feeds. This potentially provides periods of rest (and thus less hyperaemia) for an immature digestive tract. OBJECTIVES To determine the safety of shorter feeding intervals (two hours or shorter) versus longer feeding intervals (three hours or more) and to compare the effects in terms of days taken to regain birth weight and to achieve full feeding. SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to run comprehensive searches in CENTRAL (2020, Issue 6) and Ovid MEDLINE and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Daily and Versions, and CINAHL on 25 June 2020. We searched clinical trials databases and the reference lists of retrieved articles for randomised controlled trials (RCTs) and quasi-RCTs. SELECTION CRITERIA We included RCTs and quasi-RCTs comparing short (e.g. one or two hours) versus long (e.g. three or four hours) feeding intervals in preterm infants of any birth weight, all or most of whom were less than 32 weeks' gestation. Infants could be of any postnatal age at trial entry, but eligible infants should not have received feeds before study entry, with the exception of minimal enteral feeding. We included studies of nasogastric or orogastric bolus feeding, breast milk or formula, in which the feeding interval is the intervention. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. We used the GRADE approach to assess the certainty of evidence. Our primary outcomes were days taken to achieve full enteral feeding and days to regain birth weight. Our other outcomes were duration of hospital stay, episodes of necrotising enterocolitis (NEC) and growth during hospital stay (weight, length and head circumference). MAIN RESULTS We included four RCTs, involving 417 infants in the review. One study involving 350 infants is awaiting classification. All studies compared two-hourly versus three-hourly feeding interval. The risk of bias of the included studies was generally low, but all studies had high risk of performance bias due to lack of blinding of the intervention. Three studies were included in meta-analysis for the number of days taken to achieve full enteral feeding (351 participants). The mean days to achieve full feeds was between eight and 11 days. There was little or no difference in days taken to achieve full enteral feeding between two-hourly and three-hourly feeding, but this finding was of low certainty (mean difference (MD) ‒0.62, 95% confidence interval (CI) ‒1.60 to 0.36). There was low-certainty evidence that the days taken to regain birth weight may be slightly longer in infants receiving two-hourly feeding than in those receiving three-hourly feeding (MD 1.15, 95% CI 0.11 to 2.20; 3 studies, 350 participants). We are uncertain whether shorter feeding intervals have any effect on any of our secondary outcomes including the duration of hospital stay (MD ‒3.36, 95% CI ‒9.18 to 2.46; 2 studies, 207 participants; very low-certainty evidence) and the risk of NEC (typical risk ratio 1.07, 95% CI 0.54 to 2.11; 4 studies, 417 participants; low-certainty evidence). No study reported growth during hospital stay. AUTHORS' CONCLUSIONS The low-certainty evidence we found in this review suggests that there may be no clinically important differences between two- and three-hourly feeding intervals. There is insufficient information about potential feeding complications and in particular NEC. No studies have looked at the effect of other feeding intervals and there is no long-term data on neurodevelopment or growth.

Abstract
BACKGROUND There is a need to standardize monitoring in obstetric research of twin pregnancies. Identification of birth weight discordance (BWD), defined as a difference in the birth weights of twins, is a well-documented phenomenon in twin pregnancies. Ultrasound for the diagnosis of BWD informs complex decision making including whether to intervene medically (via laser photo coagulation) or deliver the twins to avoid fetal morbidities or even death. The question is, how accurate is this measurement? OBJECTIVES To determine the diagnostic accuracy (sensitivity and specificity) of ultrasound estimated fetal weight discordance (EFWD) of 20% and 25% using different estimated biometric ultrasound measurements compared with the actual BWD as the reference standard in twin pregnancies. SEARCH METHODS The search for this review was performed on 15 March 2019. We searched CENTRAL, MEDLINE (Ovid), Embase (Ovid), seven other databases, conference proceedings, reference lists and contacted experts. There were no language or date restrictions applied to the electronic searches, and no methodological filters to maximize sensitivity. SELECTION CRITERIA We selected cohort-type studies with delayed verification that evaluated the accuracy of biometric measurements at ultrasound scanning of twin pregnancies that had been proposed for the diagnosis of estimated BWD, compared to BWD measurements after birth as a reference standard. In addition, we only selected studies that considered twin pregnancies and applied a reference standard for EFWD for the target condition of BWD. DATA COLLECTION AND ANALYSIS We screened all titles generated by electronic database searches. Two review authors independently assessed the abstracts of all potentially relevant studies. We assessed the identified full papers for eligibility, and extracted data to create 2 × 2 tables. Two review authors independently performed quality assessment using the QUADAS-2 tool. We excluded studies that did not report data in sufficient detail to construct 2 × 2 tables, and where this information was not available from the primary investigators. We assessed the certainty of the evidence using the GRADE approach. MAIN RESULTS We included 39 eligible studies with a median study sample size of 140. In terms of risk of bias, there were many unclear statements regarding patient selection, index test and use of proper reference standard. Twenty-one studies (53%) were of methodological concern due to flow and timing. In terms of applicability, most studies were of low concern. Ultrasound for diagnosis of BWD in twin pregnancies at 20% cut-off Twenty-two studies provided data for a BWD of 20% and the summary estimate of sensitivity was 0.51 (95% CI 0.42 to 0.60), and the summary estimate of specificity was 0.91 (95% CI 0.89 to 0.93) (8005 twin pregnancies; very low-certainty evidence). Ultrasound for diagnosis of BWD in twin pregnancies at 25% cut-off Eighteen studies provided data using a BWD discordance of 25%. The summary estimate of sensitivity was 0.46 (95% CI 0.26 to 0.66), and the summary estimate of specificity was 0.93 (95% CI 0.89 to 0.96) (6471 twin pregnancies; very low-certainty evidence). Subgroup analyses were possible for both BWD of 20% and 25%. The diagnostic accuracy did not differ substantially between estimation by abdominal circumference and femur length but femur length had a trend towards higher sensitivity and specificity. Subgroup analyses were not possible by sex of twins, chorionicity or gestational age due to insufficient data. AUTHORS' CONCLUSIONS Very low-certainty evidence suggests that EFWD identified by ultrasound has low sensitivity but good specificity in detecting BWD in twin pregnancies. There is uncertain diagnostic value of EFWD; this review suggests there is insufficient evidence to support this index as the sole measure for clinical decision making to evaluate the prognosis of twins with growth discordance. The diagnostic accuracy of other measures including amniotic fluid index and umbilical artery Doppler resistive indices in combination with ultrasound for clinical intervention requires evaluation. Future well-designed studies could also evaluate the impact of chorionicity, sex and gestational age in the diagnostic accuracy of ultrasound for EFWD.

Comparing breastfeeding experiences between mothers spending the traditional Chinese confinement period in a confinement centre and those staying at home: a cohort study. Int Breastfeed J 2021; 16:4. [PMID: 33407645 PMCID: PMC7789407 DOI: 10.1186/s13006-020-00353-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Accepted: 12/10/2020] [Indexed: 12/05/2022] Open
Abstract
Background Ethnic Chinese mothers in Malaysia adhere to 30 days of traditional postpartum practices (the “confinement period”) aimed at recuperation after delivery. Recently there has been an emergence of confinement centres (CCs) where mothers stay and receive traditional confinement care. Ethnic Chinese mothers have low breastfeeding rates. There are concerns that practices in CCs could contribute to this but no data exists. We described mothers’ breastfeeding experiences at CCs and identified areas for potential improvement in breastfeeding support. Methods Ethnic Chinese mothers intending to breastfeed their healthy infants were recruited post-delivery between August and October 2017 then, at 1 and 6 months, they were telephone interviewed about their experience. For every participant going to a CC after the birth, another mother going home (“home”) for her confinement was recruited. Chi-square test was used to compare groups and multiple logistic regression was used to assess the effect of confinement place on exclusive breastfeeding. Results Of 187 mothers, 88 (47%) went to CCs. Significantly more were primipara and fewer had previous breastfeeding experience. Response rates for the 1- and 6- month interviews were 88% (CC) versus 97% (home); and 77% (CC) versus 87% (home) respectively. Exclusive breastfeeding rates were similar between the groups: 62% (CC) versus 56% (home) at 1 month (p = 0.4); and 37% (CC) versus 42% (home) at 6 months (p = 0.5). Multiple logistic regression did not show that CCs were a factor affecting exclusive breastfeeding rates at 1 month, (adjusted odds ratio [aOR] 1.7, 95% confidence interval [CI] 0.9, 3.3), or 6 months (aOR 0.9, 95% CI 0.4, 1.7). However, significantly more CC participants only fed expressed breast milk. Despite 66% of CC participants reporting that their centre supported breastfeeding, only 6 (8%) CC participants compared to 66 (69%) of home participants roomed-in with their baby (p < 0.001). The proportion encountering breastfeeding difficulties were similar between groups. CC participants sought help for breastfeeding problems mainly from CC staff and support groups while home participants obtained help from friends and healthcare professionals. Conclusions Breastfeeding rates appeared to be similar at CCs and at home during the confinement period, but there were gaps in how CCs supported breastfeeding. Targeted training to CC staff to support breastfeeding may result in better outcomes for mothers staying in CCs.

Early versus delayed continuous positive airway pressure (CPAP) for respiratory distress in preterm infants. Cochrane Database Syst Rev 2020; 10:CD002975. [PMID: 33058139 PMCID: PMC8094884 DOI: 10.1002/14651858.cd002975.pub2] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/11/2022]
Abstract
BACKGROUND The application of continuous positive airway pressure (CPAP) has been shown to have some benefits in the treatment of preterm infants with respiratory distress. CPAP has the potential to reduce lung damage, particularly if applied early before atelectasis has occurred. Early application may better conserve an infant's own surfactant stores and consequently may be more effective than later application. OBJECTIVES • To determine if early compared with delayed initiation of CPAP results in lower mortality and reduced need for intermittent positive-pressure ventilation in preterm infants in respiratory distress ○ Subgroup analyses were planned a priori on the basis of weight (with subdivisions at 1000 grams and 1500 grams), gestation (with subdivisions at 28 and 32 weeks), and according to whether surfactant was used ▫ Sensitivity analyses based on trial quality were also planned ○ For this update, we have excluded trials using continuous negative pressure SEARCH METHODS: We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2020, Issue 6), in the Cochrane Library; Ovid MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations Daily and Versions(R); and the Cumulative Index to Nursing and Allied Health Literatue (CINAHL), on 30 June 2020. We also searched clinical trials databases and the reference lists of retrieved articles for randomised controlled trials (RCTs) and quasi-RCTs. SELECTION CRITERIA We included trials that used random or quasi-random allocation to either early or delayed CPAP for spontaneously breathing preterm infants in respiratory distress. DATA COLLECTION AND ANALYSIS We used the standard methods of Cochrane and Cochrane Neonatal, including independent assessment of trial quality and extraction of data by two review authors. We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS We found four studies that recruited a total of 119 infants. Two were quasi-randomised, and the other two did not provide details on the method of randomisation or allocation used. None of these studies used blinding of the intervention or the outcome assessor. Evidence showed uncertainty about whether early CPAP has an effect on subsequent use of intermittent positive-pressure ventilation (IPPV) (typical risk ratio (RR) 0.77, 95% confidence interval (CI) 0.43 to 1.38; typical risk difference (RD) -0.08, 95% CI -0.23 to 0.08; I² = 0%, 4 studies, 119 infants; very low-certainty evidence) or mortality (typical RR 0.93, 95% CI 0.43 to 2.03; typical RD -0.02, 95% CI -0.15 to 0.12; I² = 33%, 4 studies, 119 infants; very low-certainty evidence). The outcome 'failed treatment' was not reported in any of these studies. There was an uncertain effect on air leak (pneumothorax) (typical RR 1.09, 95% CI 0.39 to 3.04, I² = 0%, 3 studies, 98 infants; very low-certainty evidence). No trials reported intraventricular haemorrhage or necrotising enterocolitis. No cases of retinopathy of prematurity were reported in one study (21 infants). One case of bronchopulmonary dysplasia was reported in each group in one study involving 29 infants. Long-term outcomes were not reported. AUTHORS' CONCLUSIONS All four small trials included in this review were performed in the 1970s or the early 1980s, and we are very uncertain whether early application of CPAP confers clinical benefit in the treatment of respiratory distress, or whether it is associated with any adverse effects. Further trials should be directed towards establishing the appropriate level of CPAP and the timing and method of administration of surfactant when used along with CPAP.

Abstract
BACKGROUND Respiratory distress, particularly respiratory distress syndrome (RDS), is the single most important cause of morbidity and mortality in preterm infants. In infants with progressive respiratory insufficiency, intermittent positive pressure ventilation (IPPV) with surfactant has been the usual treatment, but it is invasive, potentially resulting in airway and lung injury. Continuous positive airway pressure (CPAP) has been used for the prevention and treatment of respiratory distress, as well as for the prevention of apnoea, and in weaning from IPPV. Its use in the treatment of RDS might reduce the need for IPPV and its sequelae. OBJECTIVES To determine the effect of continuous distending pressure in the form of CPAP on the need for IPPV and associated morbidity in spontaneously breathing preterm infants with respiratory distress. SEARCH METHODS We used the standard strategy of Cochrane Neonatal to search CENTRAL (2020, Issue 6); Ovid MEDLINE and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Daily and Versions; and CINAHL on 30 June 2020. We also searched clinical trials databases and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. SELECTION CRITERIA All randomised or quasi-randomised trials of preterm infants with respiratory distress were eligible. Interventions were CPAP by mask, nasal prong, nasopharyngeal tube or endotracheal tube, compared with spontaneous breathing with supplemental oxygen as necessary. DATA COLLECTION AND ANALYSIS We used standard methods of Cochrane and its Neonatal Review Group, including independent assessment of risk of bias and extraction of data by two review authors. We used the GRADE approach to assess the certainty of evidence. Subgroup analyses were planned on the basis of birth weight (greater than or less than 1000 g or 1500 g), gestational age (groups divided at about 28 weeks and 32 weeks), timing of application (early versus late in the course of respiratory distress), pressure applied (high versus low) and trial setting (tertiary compared with non-tertiary hospitals; high income compared with low income) MAIN RESULTS: We included five studies involving 322 infants; two studies used face mask CPAP, two studies used nasal CPAP and one study used endotracheal CPAP and continuing negative pressure for a small number of less ill babies. For this update, we included one new trial. CPAP was associated with lower risk of treatment failure (death or use of assisted ventilation) (typical risk ratio (RR) 0.64, 95% confidence interval (CI) 0.50 to 0.82; typical risk difference (RD) -0.19, 95% CI -0.28 to -0.09; number needed to treat for an additional beneficial outcome (NNTB) 6, 95% CI 4 to 11; I2 = 50%; 5 studies, 322 infants; very low-certainty evidence), lower use of ventilatory assistance (typical RR 0.72, 95% CI 0.54 to 0.96; typical RD -0.13, 95% CI -0.25 to -0.02; NNTB 8, 95% CI 4 to 50; I2 = 55%; very low-certainty evidence) and lower overall mortality (typical RR 0.53, 95% CI 0.34 to 0.83; typical RD -0.11, 95% CI -0.18 to -0.04; NNTB 9, 95% CI 2 to 13; I2 = 0%; 5 studies, 322 infants; moderate-certainty evidence). CPAP was associated with increased risk of pneumothorax (typical RR 2.48, 95% CI 1.16 to 5.30; typical RD 0.09, 95% CI 0.02 to 0.16; number needed to treat for an additional harmful outcome (NNTH) 11, 95% CI 7 to 50; I2 = 0%; 4 studies, 274 infants; low-certainty evidence). There was no evidence of a difference in bronchopulmonary dysplasia, defined as oxygen dependency at 28 days (RR 1.04, 95% CI 0.35 to 3.13; I2 = 0%; 2 studies, 209 infants; very low-certainty evidence). The trials did not report use of surfactant, intraventricular haemorrhage, retinopathy of prematurity, necrotising enterocolitis and neurodevelopment outcomes in childhood. AUTHORS' CONCLUSIONS In preterm infants with respiratory distress, the application of CPAP is associated with reduced respiratory failure, use of mechanical ventilation and mortality and an increased rate of pneumothorax compared to spontaneous breathing with supplemental oxygen as necessary. Three out of five of these trials were conducted in the 1970s. Therefore, the applicability of these results to current practice is unclear. Further studies in resource-poor settings should be considered and research to determine the most appropriate pressure level needs to be considered.

Postpartum women's perception of antenatal breastfeeding education: a descriptive survey. Int Breastfeed J 2020; 15:85. [PMID: 33054789 PMCID: PMC7557059 DOI: 10.1186/s13006-020-00328-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2019] [Accepted: 10/05/2020] [Indexed: 11/26/2022] Open
Abstract
Background Antenatal breastfeeding education (ANBE) is provided to all pregnant women attending Ministry of Health (MOH) clinics and some private health facilities in Malaysia, in line with the WHO/UNICEF Baby-Friendly Hospital Initiative (BFHI). However, the 6 month exclusive breastfeeding prevalence remains relatively low in Malaysia, suggesting that there may be a gap between what is currently taught and what is received by the women. Objectives To determine how women perceived their ANBE experience in the first 8 weeks postpartum including what was useful and what they would like to have been included, sources of ANBE and infant feeding practices at the time of survey. Methods Women during their first 8 weeks postpartum who attended MOH clinics in Penang State, Malaysia were surveyed using a self-administered questionnaire in April and May 2015. Categorical responses were presented as numbers and proportions while free text responses were compiled verbatim and categorised into themes. The perceptions of primiparous and multiparous women were compared. Multivariate logistic regression adjusted to known confounders was used to determine if ANBE was associated with exclusive breastfeeding at the time of survey. Results A total of 421 women completed the 15-item questionnaire (84% response rate) of which 282 were complete and available for analysis. Of these, 95% had received ANBE, majority (88%) from MOH clinics. Almost all women found it useful. However, there were areas both in the delivery (e.g. too short) and the content (e.g. nothing new) that were described as not useful; and areas they would like more coverage (e.g. milk expression, storage and overcoming low milk supply). The exclusive breastfeeding prevalence at the time of survey was 61%. ANBE was significantly associated with exclusive breastfeeding even after adjusting for confounders (adjusted odds ratio [aOR] 8.1, 95% confidence interval 1.7, 38.3). Conclusions ANBE is widely implemented and perceived as useful and may be associated with exclusive breastfeeding. Our findings give insight into content that women would like more of and how delivery of ANBE could be improved, including individualized sessions and communicating at a suitable level and language. Future studies could focus on the quality of ANBE delivery.

Abstract
BACKGROUND Phototherapy is a well-established effective therapy for treating babies with significant neonatal jaundice. Studies have shown that increasing light intensity will increase its efficiency. A potentially inexpensive and easy way of increasing the intensity of light on the body of the infant may be to hang reflective materials from the sides of phototherapy units. OBJECTIVES To assess the effects of reflective materials in combination with phototherapy compared with phototherapy alone for unconjugated hyperbilirubinaemia in neonates. SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2019, Issue 11), in the Cochrane Library; Ovid MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Daily and Versions(R); and the Cumulative Index of Nursing and Allied Health Literature (CINAHL), on 1 November 2019. We also searched clinical trials databases and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. SELECTION CRITERIA We included randomised and quasi-randomised controlled trials if the participants, who were term or preterm infants, received phototherapy with curtains made of reflective materials of any type in the treatment arm, and if those in the comparison arm received similar phototherapy without curtains or other intensified phototherapy, such as a double bank of lights. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS Of 15 studies identified, we included 12 (1288 babies) in the review - 11 comparing phototherapy with reflective materials and phototherapy alone, and one comparing a single phototherapy light bank with reflective materials with double phototherapy. All reflective materials consisted of curtains on three or four sides of the cot and were made of white plastic (five studies), white linen (two studies), or aluminium (three studies); materials were not specified in two studies. Only 11 studies (10 comparing reflective materials versus none and one comparing reflective curtains and a single bank of lights with a double (above and below) phototherapy unit) provided sufficient data to be included in the meta-analysis. Two excluded studies used the reflective materials in a way that did not meet our inclusion criteria, and we excluded one study because it compared four different phototherapy interventions not including reflective materials. The risk of bias of included studies was generally low, but all studies had high risk of performance bias due to lack of blinding of the intervention. Three studies (281 participants) reported a decline in serum bilirubin (SB) (μmol/L) at four to eight hours (mean difference (MD) -14.61, 95% confidence interval (CI) -19.80 to -9.42; I² = 57%; moderate-certainty evidence). Nine studies (893 participants) reported a decline in SB over 24 hours and showed a faster decline in SB in the intervention group, but heterogeneity (I² = 97%) was too substantial to permit a meaningful estimate of the actual effect size (very low-certainty evidence). Subgroup analysis by type of reflective material used did not explain the heterogeneity. Exchange transfusion was reported by two studies; both reported none in either group. Four studies (466 participants) reported the mean duration of phototherapy, and in each of these studies, it was reduced in the intervention group but there was substantial heterogeneity (I² = 88%), precluding meaningful meta-analysis of data. The only two studies that reported the mean duration of hospital stay in hours showed a meaningful reduction (MD -41.08, 95% CI -45.92 to -36.25; I² = 0; moderate-certainty evidence). No studies reported costs of the intervention, parental or medical staff satisfaction, breastfeeding outcomes, or neurodevelopmental follow-up. The only study that compared use of curtains with double phototherapy reported similar results for both groups. Studies that monitored adverse events did not report increased adverse events related to the use of curtains, including acute life-threatening events, but other rarer side effects could not be excluded. AUTHORS' CONCLUSIONS Moderate-certainty evidence shows that the use of reflective curtains during phototherapy may result in greater decline in SB. Very low-certainty evidence suggests that the duration of phototherapy is reduced, and moderate-certainty evidence shows that the duration of hospital stay is also reduced. Available evidence does not show any increase in adverse events, but further studies are needed.

Oral galactagogues (natural therapies or drugs) for increasing breast milk production in mothers of non-hospitalised term infants. Cochrane Database Syst Rev 2020; 5:CD011505.

Abstract
BACKGROUND Many women express concern about their ability to produce enough milk, and insufficient milk is frequently cited as the reason for supplementation and early termination of breastfeeding. When addressing this concern, it is important first to consider the influence of maternal and neonatal health, infant suck, proper latch, and feeding frequency on milk production, and that steps be taken to correct or compensate for any contributing issues. Oral galactagogues are substances that stimulate milk production. They may be pharmacological or non-pharmacological (natural). Natural galactagogues are usually botanical or other food agents. The choice between pharmacological or natural galactagogues is often influenced by familiarity and local customs. Evidence for the possible benefits and harms of galactagogues is important for making an informed decision on their use. OBJECTIVES To assess the effect of oral galactagogues for increasing milk production in non-hospitalised breastfeeding mother-term infant pairs. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register, ClinicalTrials.gov, the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP), Health Research and Development Network - Phillippines (HERDIN), Natural Products Alert (Napralert), the personal reference collection of author LM, and reference lists of retrieved studies (4 November 2019). SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs (including published abstracts) comparing oral galactagogues with placebo, no treatment, or another oral galactagogue in mothers breastfeeding healthy term infants. We also included cluster-randomised trials but excluded cross-over trials. DATA COLLECTION AND ANALYSIS We used standard Cochrane Pregnancy and Childbirth methods for data collection and analysis. Two to four review authors independently selected the studies, assessed the risk of bias, extracted data for analysis and checked accuracy. Where necessary, we contacted the study authors for clarification. MAIN RESULTS Forty-one RCTs involving 3005 mothers and 3006 infants from at least 17 countries met the inclusion criteria. Studies were conducted either in hospitals immediately postpartum or in the community. There was considerable variation in mothers, particularly in parity and whether or not they had lactation insufficiency. Infants' ages at commencement of the studies ranged from newborn to 6 months. The overall certainty of evidence was low to very low because of high risk of biases (mainly due to lack of blinding), substantial clinical and statistical heterogeneity, and imprecision of measurements. Pharmacological galactagogues Nine studies compared a pharmacological galactagogue (domperidone, metoclopramide, sulpiride, thyrotropin-releasing hormone) with placebo or no treatment. The primary outcome of proportion of mothers who continued breastfeeding at 3, 4 and 6 months was not reported. Only one study (metoclopramide) reported on the outcome of infant weight, finding little or no difference (mean difference (MD) 23.0 grams, 95% confidence interval (CI) -47.71 to 93.71; 1 study, 20 participants; low-certainty evidence). Three studies (metoclopramide, domperidone, sulpiride) reported on milk volume, finding pharmacological galactagogues may increase milk volume (MD 63.82 mL, 95% CI 25.91 to 101.72; I² = 34%; 3 studies, 151 participants; low-certainty evidence). Subgroup analysis indicates there may be increased milk volume with each drug, but with varying CIs. There was limited reporting of adverse effects, none of which could be meta-analysed. Where reported, they were limited to minor complaints, such as tiredness, nausea, headache and dry mouth (very low-certainty evidence). No adverse effects were reported for infants. Natural galactagogues Twenty-seven studies compared natural oral galactagogues (banana flower, fennel, fenugreek, ginger, ixbut, levant cotton, moringa, palm dates, pork knuckle, shatavari, silymarin, torbangun leaves or other natural mixtures) with placebo or no treatment. One study (Mother's Milk Tea) reported breastfeeding rates at six months with a concluding statement of "no significant difference" (no data and no measure of significance provided, 60 participants, very low-certainty evidence). Three studies (fennel, fenugreek, moringa, mixed botanical tea) reported infant weight but could not be meta-analysed due to substantial clinical and statistical heterogeneity (I2 = 60%, 275 participants, very low-certainty evidence). Subgroup analysis shows we are very uncertain whether fennel or fenugreek improves infant weight, whereas moringa and mixed botanical tea may increase infant weight compared to placebo. Thirteen studies (Bu Xue Sheng Ru, Chanbao, Cui Ru, banana flower, fenugreek, ginger, moringa, fenugreek, ginger and turmeric mix, ixbut, mixed botanical tea, Sheng Ru He Ji, silymarin, Xian Tong Ru, palm dates; 962 participants) reported on milk volume, but meta-analysis was not possible due to substantial heterogeneity (I2 = 99%). The subgroup analysis for each intervention suggested either benefit or little or no difference (very low-certainty evidence). There was limited reporting of adverse effects, none of which could be meta-analysed. Where reported, they were limited to minor complaints such as mothers with urine that smelled like maple syrup and urticaria in infants (very low-certainty evidence). Galactagogue versus galactagogue Eight studies (Chanbao; Bue Xue Sheng Ru, domperidone, moringa, fenugreek, palm dates, torbangun, moloco, Mu Er Wu You, Kun Yuan Tong Ru) compared one oral galactagogue with another. We were unable to perform meta-analysis because there was only one small study for each match-up, so we do not know if one galactagogue is better than another for any outcome. AUTHORS' CONCLUSIONS Due to extremely limited, very low certainty evidence, we do not know whether galactagogues have any effect on proportion of mothers who continued breastfeeding at 3, 4 and 6 months. There is low-certainty evidence that pharmacological galactagogues may increase milk volume. There is some evidence from subgroup analyses that natural galactagogues may benefit infant weight and milk volume in mothers with healthy, term infants, but due to substantial heterogeneity of the studies, imprecision of measurements and incomplete reporting, we are very uncertain about the magnitude of the effect. We are also uncertain if one galactagogue performs better than another. With limited data on adverse effects, we are uncertain if there are any concerning adverse effects with any particular galactagogue; those reported were minor complaints. High-quality RCTs on the efficacy and safety of galactagogues are urgently needed. A set of core outcomes to standardise infant weight and milk volume measurement is also needed, as well as a strong basis for the dose and dosage form used.

Abstract
BACKGROUND Oedema is a common clinical symptom in people with nephrotic syndrome and human albumin has been widely used in the treatment of oedema by increasing vascular volume and this inducing diuresis. It may be used with or without diuretics such as furosemide. However, the quantitative contribution of human albumin in treating oedema is not fully understood. If human albumin were found to be effective and safe in the treatment of oedema, it could help clinicians to develop therapeutic strategies to improve the management of diuretic resistance associated with nephrotic syndrome. OBJECTIVES This review aimed to examine the benefits and harms of human albumin infusion for treating oedema associated with nephrotic syndrome. SEARCH METHODS We searched the Cochrane Kidney and Transplant Register of Studies up to 23 June 2019 through contact with the Information Specialists using search terms relevant to this review. Studies in the Specialised Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs evaluating the effect of human albumin infusion compared with placebo or no intervention, human albumin with diuretics compared with diuretic alone, human albumin compared with diuretics and other treatments, clinical outcomes, death, quality of life, kidney function and adverse effects in people with nephrotic syndrome. We excluded cross-over studies but data for the first period was to be included if available. DATA COLLECTION AND ANALYSIS Standard methods of the Cochrane Collaboration were used. Two authors independently assessed eligibility, risk of bias, study quality and extracted data. We calculated mean difference (MD) for continuous data with 95% confidence intervals (CI). We assessed the certainty of the evidence using GRADE. MAIN RESULTS One study met our inclusion criteria (26 children with minimal change nephrotic syndrome) and 11 were excluded (nine cross-over studies, one where albumin was not used for nephrotic syndrome and one where authors did not state whether the children had oedema). Risk of bias for the included study was unclear for selection bias, high for performance and detection bias, low for attrition bias, and high for selective reporting. The included study compared albumin plus furosemide with an equal volume of dextrose. Of our prespecified outcomes, the authors reported clinical improvement as weight change, serum sodium and adverse outcomes (blood pressure). The authors reported a greater weight loss in the albumin treated group initially but no difference overall at 10 days. However, the data in the text and the figures were inconsistent so we could not confirm the authors statements (very low certainty evidence). It is uncertain whether albumin infusion improves serum sodium when compared with an equal volume of dextrose (MD 2.00 mEq/L, 95% CI -0.09 to 4.09), systolic blood pressure (MD 2.00 mmHg, 95% CI -3.52 to 7.52) or diastolic blood pressure (MD 2.00 mmHg, 95%CI -4.29 to 8.29). Death, quality of life, and kidney function were not reported. AUTHORS' CONCLUSIONS We identified only one small study that was relevant to our review, therefore we are unable to draw any conclusions regarding the use of human albumin with or without diuretics in nephrotic syndrome. More RCTs are needed.

The effect of rooming-in on duration of breastfeeding: A systematic review of randomised and non-randomised prospective controlled studies. PLoS One 2019; 14:e0215869. [PMID: 31022227 PMCID: PMC6483355 DOI: 10.1371/journal.pone.0215869] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2019] [Accepted: 04/05/2019] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND The benefits of six months exclusive breastfeeding are well established for both mother and infant. One of the 10 steps of the Baby Friendly Hospital Initiative is rooming-in (mother and baby together in the same room throughout hospitalisation). A Cochrane review found only one randomised controlled trial (RCT) examining the effects of continuous rooming-in versus nursery care on breastfeeding duration, and concluded there was insufficient evidence to support or refute either practice. We aimed to examine the effect of continuous or intermittent rooming-in on breastfeeding duration. METHODS AND FINDINGS We included all prospective controlled studies (randomised and non-randomised) comparing rooming-in to nursery care that reported full or partial breastfeeding up to six months. We used the 2016 search results of the Cochrane review and updated the search to August 2018 using OVID MEDLINE. Duplicate data extraction and assessment of risk of bias were performed. Meta-analyses were performed using REVMAN 5. The GRADE approach was used to assess quality of evidence. Seven studies were included, five had 24-hour-per-day, one daytime only and one 8-hours-per-day rooming-in. Four studies had at least one additional co-intervention: Differences in delivery room management, and educational packages. All studies contributing to meta-analyses had 24-hour rooming-in. There was no difference in the proportion of infants on full breastfeeding at 3 months (RR 1.14; 95% CI 0.84 to 1.54; very-low-quality evidence), 4 months (RR 0.99; 95% CI 0.73 to 1.33; very-low-quality evidence) and 6 months (RR 0.95; 95% CI 0.57 to 1.58; low-quality evidence). The proportion of infants on partial breastfeeding at 3-4 months was higher with rooming-in (RR 1.31; 95% CI 1.06 to 1.61; very-low-quality evidence). CONCLUSION The addition of non-randomised prospective controlled studies to existing evidence did not add further information on the effects of rooming-in on breastfeeding duration but resulted in lower quality of evidence. Uncertainty about the effects of rooming-in on breastfeeding duration remains.

Abstract
BACKGROUND Acute otitis media (AOM) is one of the most common infectious diseases in children. It has been reported that 64% of infants have an episode of AOM by the age of six months and 86% by one year. Although most cases of AOM are due to bacterial infection, it is commonly triggered by a viral infection. In most children AOM is self limiting, but it does carry a risk of complications. Since antibiotic treatment increases the risk of antibiotic resistance, influenza vaccines might be an effective way of reducing this risk by preventing the development of AOM. OBJECTIVES To assess the effectiveness of influenza vaccine in reducing the occurrence of acute otitis media in infants and children. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, CINAHL, LILACS, Web of Science, the WHO International Clinical Trials Registry Platform, and ClinicalTrials.gov (15 February 2017). We also searched the reference lists of included studies to identify any additional trials. SELECTION CRITERIA Randomised controlled trials comparing influenza vaccine with placebo or no treatment in infants and children aged younger than six years. We included children of either sex and of any ethnicity, with or without a history of recurrent AOM. DATA COLLECTION AND ANALYSIS Two review authors independently screened studies, assessed trial quality, and extracted data. We performed statistical analyses using the random-effects and fixed-effect models and expressed the results as risk ratio (RR), risk difference (RD), and number needed to treat for an additional beneficial outcome (NNTB) for dichotomous outcomes, with 95% confidence intervals (CI). MAIN RESULTS We included 11 trials (6 trials in high-income countries and 5 multicentre trials in high-, middle-, and low-income countries) involving 17,123 children aged 6 months to 6 years. Eight trials recruited participants from a healthcare setting. Ten trials (and all four trials that contributed to the primary outcome) declared funding from vaccine manufacturers. Four trials reported adequate allocation concealment, and 10 trials reported adequate blinding of participants and personnel. Attrition was low for eight trials included in the analysis.The primary outcome showed a small reduction in at least one episode of AOM over at least six months of follow-up (4 trials, 3134 children; RR 0.84, 95% CI 0.69 to 1.02; RD -0.04, 95% CI -0.08 to -0.00; NNTB 25, 95% CI 12.5 to 100; low-quality evidence).The subgroup analyses (i.e. number of courses and types of vaccine administered) showed no differences.There was a reduction in the use of antibiotics in vaccinated children (2 trials, 1223 children; RR 0.70, 95% CI 0.59 to 0.83; RD -0.11, 95% CI -0.16 to -0.06; moderate-quality evidence).We were unable to demonstrate whether there was any difference in the utilisation of health care. The use of influenza vaccine resulted in a significant increase in fever (7 trials, 10,615 children; RR 1.15, 95% CI 1.06 to 1.24; RD 0.02, 95% CI 0.00 to 0.04; low-quality evidence), rhinorrhoea (6 trials, 10,563 children; RR 1.17, 95% CI 1.07 to 1.29; RD 0.09, 95% CI 0.01 to 0.16; low-quality evidence), but no difference in pharyngitis. No major adverse events were reported.Differing from the protocol, the original publication of the review included a subgroup analysis of AOM episodes by season, and the secondary outcome 'types of influenza vaccine' was changed to a subgroup analysis. For this update, we removed the subgroup analyses for trial setting, season, and utilisation of health care due to the small number of trials involved. We removed Belshe 2000 from primary and secondary outcomes (courses of vaccine and types of vaccine) because it reported episodes of AOM per person. We did not perform a subgroup analysis by type of adverse event. We have reported each type of adverse event as a separate analysis. AUTHORS' CONCLUSIONS Influenza vaccine results in a small reduction in AOM. The observed reduction in the use of antibiotics needs to be considered in light of current recommended practices aimed at avoiding antibiotic overuse. Safety data from these trials were limited. The benefits may not justify the use of influenza vaccine without taking into account the vaccine efficacy in reducing influenza and safety data. We judged the quality of the evidence to be low to moderate. Additional research is needed.

Abstract
BACKGROUND Breast milk is well recognised as the best food source for infants. The impact of antenatal breastfeeding (BF) education on the duration of BF has not been evaluated. OBJECTIVES To assess the effectiveness of antenatal breastfeeding (BF) education for increasing BF initiation and duration. SEARCH METHODS We searched Cochrane Pregnancy and Childbirth's Trials Register on 1 March 2016, CENTRAL (The Cochrane Library, 2016, Issue 3), MEDLINE (1966 to 1 March 2016) and Scopus (January 1985 to 1 March 2016). We contacted experts and searched reference lists of retrieved articles. SELECTION CRITERIA All identified published, unpublished and ongoing randomised controlled trials (RCTs) assessing the effect of formal antenatal BF education or comparing two different methods of formal antenatal BF education, on the duration of BF. We included RCTs that only included antenatal interventions and excluded those that combined antenatal and intrapartum or postpartum BF education components. Cluster-randomised trials were included in this review. Quasi-randomised trials were not eligible for inclusion. DATA COLLECTION AND ANALYSIS We assessed all potential studies identified as a result of the search strategy. Two review authors extracted data from each included study using the agreed form and assessed risk of bias. We resolved discrepancies through discussion. We assessed the quality of the evidence using the GRADE approach. MAIN RESULTS This review update includes 24 studies (10,056 women). Twenty studies (9789 women) contribute data to analyses. Most studies took place in high-income countries such as the USA, UK, Canada and Australia. In the first five comparisons, we display the included trials according to type of intervention without pooling data. For the 'Summary of findings' we pooled data for a summary effect.Five included studies were cluster-randomised trials: all of these adjusted data and reported adjustments as odds ratios (OR). We have analysed the data using the generic inverse variance method and presented results as odds ratios, because we were unable to derive a cluster-adjusted risk ratio from the published cluster-trial. We acknowledge that the use of odds ratio prevents the pooling of these cluster trials in our main analyses. One method of BF education with standard (routine) careThere were no group differences for duration of any BF in days or weeks. There was no evidence that interventions improved the proportion of women with any BF or exclusive BF at three or six months. Single trials of different interventions were unable to show that education improved initiation of BF, apart from one small trial at high risk of attrition bias. Many trial results marginally favoured the intervention but had wide confidence intervals crossing the line of no effect. BF complications such as mastitis and other BF problems were similar in treatment arms in single trials reporting these outcomes. Multiple methods of BF education versus standard careFor all trials included in this comparison we have presented the cluster-adjusted odds ratios as reported in trial publications. One three-arm study found the intervention of BF booklet plus video plus Lactation Consultant versus standard care improved the proportion of women exclusively BF at three months (OR 2.60, 95% CI 1.25 to 5.40; women = 159) and marginally at six months (OR 2.40, 95% CI 1.00 to 5.76; women = 175). For the same trial, an intervention arm without a lactation consultant but with the BF booklet and video did not have the same effect on proportion of women exclusively BF at three months (OR 1.80, 95% CI 0.80 to 4.05; women = 159) or six months (OR 0.90, 95% CI 0.30 to 2.70; women = 184). One study compared monthly BF sessions and weekly cell phone message versus standard care and reported improvements in the proportion of women exclusively BF at both three and six months (three months OR 1.80, 95% CI 1.10 to 2.95; women = 390; six months OR 2.40, 95% CI 1.40 to 4.11; women = 390). One study found monthly BF sessions and weekly cell phone messages improved initiation of BF over standard care (OR 2.61, 95% CI 1.61 to 4.24; women = 380). BF education session versus standard care, pooled analyses for 'Summary of findings' (SoF)This comparison does not include cluster-randomised trials reporting adjusted odds ratios. We did not downgrade any evidence for trials' lack of blinding; no trial had adequate blinding of staff and participants. The SoF table presents risk ratios for all outcomes analysed. For proportion of women exclusively BF there is no evidence that antenatal BF education improved BF at three months (RR 1.06, 95% CI 0.90 to 1.25; women = 822; studies = 3; moderate quality evidence) or at six months (RR 1.07, 95% CI 0.87 to 1.30; women = 2161; studies = 4; moderate quality evidence). For proportion of women with any BF there were no group differences in BF at three (average RR 0.98, 95% CI 0.82 to 1.18; women = 654; studies = 2; I² = 60%; low-quality evidence) or six months (average RR 1.05, 95% CI 0.90 to 1.23; women = 1636; studies = 4; I² = 61%; high-quality evidence). There was no evidence that antenatal BF education could improve initiation of BF (average RR 1.01, 95% CI 0.94 to 1.09; women = 3505; studies = 8; I² = 69%; high-quality evidence). Where we downgraded evidence this was due to small sample size or wide confidence intervals crossing the line of no effect, or both.There was insufficient data for subgroup analysis of mother's occupation or education. AUTHORS' CONCLUSIONS There was no conclusive evidence supporting any antenatal BF education for improving initiation of BF, proportion of women giving any BF or exclusively BF at three or six months or the duration of BF. There is an urgent need to conduct a high-quality, randomised controlled study to evaluate the effectiveness and adverse effects of antenatal BF education, especially in low- and middle-income countries. Evidence in this review is primarily relevant to high-income settings.

Abstract
BACKGROUND Non-transfusion dependent beta thalassaemia is a subset of inherited haemoglobin disorders characterised by reduced production of the beta globin chain of the haemoglobin molecule leading to anaemia of varying severity. Although blood transfusion is not a necessity for survival, it is required when episodes of chronic anaemia occur. This chronic anaemia can impair growth and affect quality of life. People with non-transfusion dependent beta thalassaemia suffer from iron overload due to their body's increased capability of absorbing iron from food sources. Iron overload becomes more pronounced in those requiring blood transfusion. People with a higher foetal haemoglobin level have been found to require fewer blood transfusions. Hydroxyurea has been used to increase foetal haemoglobin level; however, its efficacy in reducing transfusion, chronic anaemia complications and its safety need to be established. OBJECTIVES To assess the effectiveness, safety and appropriate dose regimen of hydroxyurea in people with non-transfusion dependent beta thalassaemia (haemoglobin E combined with beta thalassaemia and beta thalassaemia intermedia). SEARCH METHODS We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Haemoglobinopathies Trials Register, compiled from electronic database searches and handsearching of relevant journals. We also searched ongoing trials registries and the reference lists of relevant articles and reviews.Date of last search: 30 April 2016. SELECTION CRITERIA Randomised or quasi-randomised controlled trials of hydroxyurea in people with non-transfusion dependent beta thalassaemia comparing hydroxyurea with placebo or standard treatment or comparing different doses of hydroxyurea. DATA COLLECTION AND ANALYSIS Two authors independently applied the inclusion criteria in order to select trials for inclusion. Both authors assessed the risk of bias of trials and extracted the data. A third author verified these assessments. MAIN RESULTS No trials comparing hydroxyurea with placebo or standard care were found. However, we included one randomised controlled trial (n = 61) comparing 20 mg/kg/day with 10 mg/kg/day of hydroxyurea for 24 weeks.Both haemoglobin and foetal haemoglobin levels were lower at 24 weeks in the 20 mg group compared with the 10 mg group, mean difference -2.39 (95% confidence interval - 2.8 to -1.98) and mean difference -1.5 (95% confidence interval -1.83 to -1.17), respectively. Major adverse effects were significantly more common in the 20 mg group, for neutropenia risk ratio 9.93 (95% confidence interval 1.34 to 73.97) and for thrombocytopenia risk ratio 3.68 (95% confidence interval 1.13 to 12.07). No difference was reported for minor adverse effects (gastrointestinal disturbances and raised liver enzymes). The effect of hydroxyurea on transfusion frequency was not reported.The overall quality for the outcomes reported was graded as very low mainly because the outcomes were derived from only one small study with an unclear method of allocation concealment. AUTHORS' CONCLUSIONS There is no evidence from randomised controlled trials to show whether hydroxyurea has any effect compared with controls on the need for blood transfusion. Administration of 10 mg/kg/day compared to 20 mg/kg/day of hydroxyurea resulted in higher haemoglobin levels and seems safer with fewer adverse effects. It has not been reported whether hydroxyurea is capable of reducing the need for blood transfusion. Large well-designed randomised controlled trials with sufficient duration of follow up are recommended.

Abstract
BACKGROUND About 5% of school children have a specific learning disorder, defined as unexpected failure to acquire adequate abilities in reading, writing or mathematics that is not a result of reduced intellectual ability, inadequate teaching or social deprivation. Of these events, 80% are reading disorders. Polyunsaturated fatty acids (PUFAs), in particular, omega-3 and omega-6 fatty acids, which normally are abundant in the brain and in the retina, are important for learning. Some children with specific learning disorders have been found to be deficient in these PUFAs, and it is argued that supplementation of PUFAs may help these children improve their learning abilities. OBJECTIVES 1. To assess effects on learning outcomes of supplementation of polyunsaturated fatty acids (PUFAs) for children with specific learning disorders.2. To determine whether adverse effects of supplementation of PUFAs are reported in these children. SEARCH METHODS In November 2015, we searched CENTRAL, Ovid MEDLINE, Embase, PsycINFO, 10 other databases and two trials registers. We also searched the reference lists of relevant articles. SELECTION CRITERIA Randomised controlled trials (RCTs) or quasi-RCTs comparing PUFAs with placebo or no treatment in children younger than 18 years with specific learning disabilities, as diagnosed in accordance with the fifth (or earlier) edition of theDiagnostic and Statistical Manual of Mental Disorders (DSM-5), or the 10th (or earlier) revision of the International Classification of Diseases (ICD-10) or equivalent criteria. We included children with coexisting developmental disorders such as attention deficit hyperactivity disorder (ADHD) or autism. DATA COLLECTION AND ANALYSIS Two review authors (MLT and KHT) independently screened the titles and abstracts of articles identified by the search and eliminated all studies that did not meet the inclusion criteria. We contacted study authors to ask for missing information and clarification, when needed. We used the GRADE approach to assess the quality of evidence. MAIN RESULTS Two small studies involving 116 children, mainly boys between 10 and 18 years of age, met the inclusion criteria. One study was conducted in a school setting, the other at a specialised clinic. Both studies used three months of a combination of omega-3 and omega-6 supplements as the intervention compared with placebo. Although both studies had generally low risk of bias, we judged the risk of reporting bias as unclear in one study, and as high in the other study. In addition, one of the studies was funded by industry and reported active company involvement in the study.None of the studies reported data on the primary outcomes of reading, writing, spelling and mathematics scores, as assessed by standardised tests.Evidence of low quality indicates that supplementation of PUFAs did not increase the risk of gastrointestinal disturbances (risk ratio 1.43, 95% confidence interval 0.25 to 8.15; two studies, 116 children). Investigators reported no other adverse effects.Both studies reported attention deficit hyperactivity disorder (ADHD)-related behaviour outcomes. We were unable to combine the results in a meta-analysis because one study reported findings as a continuous outcome, and the other as a dichotomous outcome. No other secondary outcomes were reported.We excluded one study because it used a cointervention (carnosine), and five other studies because they did not provide a robust diagnosis of a specific learning disorder. We identified one ongoing study and found three studies awaiting classification. AUTHORS' CONCLUSIONS Evidence is insufficient to permit any conclusions about the effect of PUFAs on the learning abilities of children with specific learning disorders. Well-designed RCTs with clearly defined populations of children with specific learning disorders who have been diagnosed by standardised diagnostic criteria are needed.

Effect of restricted pacifier use in breastfeeding term infants for increasing duration of breastfeeding. Cochrane Database Syst Rev 2016; 2016:CD007202. [PMID: 27572944 PMCID: PMC8520760 DOI: 10.1002/14651858.cd007202.pub4] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/11/2022]
Abstract
BACKGROUND To successfully initiate and maintain breastfeeding for a longer duration, the World Health Organization's Ten Steps to Successful Breastfeeding recommends total avoidance of artificial teats or pacifiers for breastfeeding infants. Concerns have been raised that offering the pacifier instead of the breast to calm the infant may lead to less frequent episodes of breastfeeding and as a consequence may reduce breast-milk production and shorten duration of breastfeeding. OBJECTIVES To assess the effect of restricted versus unrestricted pacifier use in healthy full-term newborns whose mothers have initiated breastfeeding and intend to exclusively breastfeed, on the duration of breastfeeding, other breastfeeding outcomes and infant health. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 June 2016) and reference lists of retrieved studies. SELECTION CRITERIA Randomised and quasi-randomised controlled trials comparing restricted versus unrestricted pacifier use in healthy full-term newborns who have initiated breastfeeding. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. The quality of the evidence was assessed using the GRADE approach. MAIN RESULTS We found three trials (involving 1915 babies) for inclusion in the review, but have included only two trials (involving 1302 healthy full-term breastfeeding infants) in the analysis. Meta-analysis of the two combined studies showed that pacifier use in healthy breastfeeding infants had no significant effect on the proportion of infants exclusively breastfed at three months (risk ratio (RR) 1.01; 95% confidence interval (CI) 0.96 to 1.07, two studies, 1228 infants), and at four months of age (RR 1.01; 95% CI 0.94 to 1.09, one study, 970 infants, moderate-quality evidence), and also had no effect on the proportion of infants partially breastfed at three months (RR 1.00; 95% CI 0.98 to 1.02, two studies, 1228 infants), and at four months of age (RR 0.99; 95% CI 0.97 to 1.02, one study, 970 infants). None of the included trials reported data on the other primary outcomes, i.e. duration of partial or exclusive breastfeeding, or secondary outcomes: breastfeeding difficulties (mastitis, cracked nipples, breast engorgement); infant's health (dental malocclusion, otitis media, oral candidiasis; sudden infant death syndrome (SIDS)); maternal satisfaction and level of confidence in parenting. One study reported that avoidance of pacifiers had no effect on cry/fuss behavior at ages four, six, or nine weeks and also reported no effect on the risk of weaning before age three months, however the data were incomplete and so could not be included for analysis. AUTHORS' CONCLUSIONS Pacifier use in healthy term breastfeeding infants, started from birth or after lactation is established, did not significantly affect the prevalence or duration of exclusive and partial breastfeeding up to four months of age. Evidence to assess the short-term breastfeeding difficulties faced by mothers and long-term effect of pacifiers on infants' health is lacking.

Rooming-in for new mother and infant versus separate care for increasing the duration of breastfeeding. Cochrane Database Syst Rev 2016; 2016:CD006641. [PMID: 27562563 PMCID: PMC9168801 DOI: 10.1002/14651858.cd006641.pub3] [Citation(s) in RCA: 43] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/27/2022]
Abstract
BACKGROUND Mother-infant proximity and interactions after birth and during the early postpartum period are important for breast-milk production and breastfeeding success. Rooming-in and separate care are both traditional practices. Rooming-in involves keeping the mother and the baby together in the same room after birth for the duration of hospitalisation, whereas separate care is keeping the baby in the hospital nursery and the baby is either brought to the mother for breastfeeding or she walks to the nursery. OBJECTIVES To assess the effect of mother-infant rooming-in versus separation on the duration of breastfeeding (exclusive and total duration of breastfeeding). SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 May 2016) and reference lists of retrieved studies. SELECTION CRITERIA Randomised or quasi-randomised controlled trials (RCTs) investigating the effect of mother-infant rooming-in versus separate care after hospital birth or at home on the duration of breastfeeding, proportion of breastfeeding at six months and adverse neonatal and maternal outcomes. DATA COLLECTION AND ANALYSIS Two review authors independently assessed the studies for inclusion and assessed trial quality. Two review authors extracted data. Data were checked for accuracy. We assessed the quality of the evidence using the GRADE approach. MAIN RESULTS We included one trial (involving 176 women) in this review. This trial included four groups with a factorial design. The factorial design took into account two factors, i.e. infant location in relation to the mother and the type of infant apparel. We combined three of the groups as the intervention (rooming-in) group and the fourth group acted as the control (separate care) and we analysed the results as a single pair-wise comparison. Primary outcomesThe primary outcome, duration of any breastfeeding, was reported by authors as median values because the distribution was found to be skewed. They reported the overall median duration of any breastfeeding to be four months, with no difference found between groups. Duration of exclusive breastfeeding and the proportion of infants being exclusively breastfed at six months of age was not reported in the trial. There was no difference found between the two groups in the proportion of infants receiving any breastfeeding at six months of age (risk ratio (RR) 0.84, 95% confidence interval (CI) 0.51 to 1.39; one trial; 137 women; low-quality evidence). Secondary outcomesThe mean frequency of breastfeeds per day on day four postpartum for the rooming-in group was 8.3 (standard deviation (SD) 2.2), slightly higher than the separate care group, i.e. seven times per day. However, between-group comparison of this outcome was not appropriate since every infant in the separate care group was breastfed at a fixed schedule of seven times per day (SD = 0) resulting in no estimable comparison. The rate of exclusive breastfeeding on day four postpartum before discharge from hospital was significantly higher in the rooming-in group 86% (99 of 115) compared with separate care group, 45% (17 of 38), (RR 1.92; 95% CI 1.34 to 2.76; one trial, 153 women; low-quality evidence). None of our other pre-specified secondary outcomes were reported. AUTHORS' CONCLUSIONS We found little evidence to support or refute the practice of rooming-in versus mother-infant separation. Further well-designed RCTs to investigate full mother-infant rooming-in versus partial rooming-in or separate care including all important outcomes are needed.

Prophylactic nasal continuous positive airway pressure for preventing morbidity and mortality in very preterm infants. Cochrane Database Syst Rev 2016:CD001243. [PMID: 27315509 DOI: 10.1002/14651858.cd001243.pub3] [Citation(s) in RCA: 76] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/06/2022]
Abstract
BACKGROUND Cohort studies have suggested that nasal continuous positive airways pressure (CPAP) starting in the immediate postnatal period before the onset of respiratory disease (prophylactic CPAP) may be beneficial in reducing the need for intubation and intermittent positive pressure ventilation (IPPV) and in preventing bronchopulmonary dysplasia (BPD) in preterm or low birth weight infants. OBJECTIVES To determine if prophylactic nasal CPAP started soon after birth regardless of respiratory status in the very preterm or very low birth weight infant reduces the use of IPPV and the incidence of bronchopulmonary dysplasia (BPD) without adverse effects. SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL 2016, Issue 1), MEDLINE via PubMed (1966 to 31 January 2016), EMBASE (1980 to 31 January 2016), and CINAHL (1982 to 31 January 2016). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. SELECTION CRITERIA All trials using random or quasi-random patient allocation of very preterm infants (under 32 weeks' gestation) or less than 1500 grams at birth were eligible. We included trials if they compared prophylactic nasal CPAP started soon after birth regardless of the respiratory status of the infant with 'standard' methods of treatment such as IPPV, oxygen therapy or supportive treatment. We excluded studies where prophylactic CPAP was compared with CPAP along with other interventions. DATA COLLECTION AND ANALYSIS We used the standard methods of Cochrane and its Neonatal Review Group, including independent study selection, assessment of trial quality and extraction of data by two authors. Data were analysed using risk ratio (RR) and the meta-analysis was performed using a fixed-effect model. MAIN RESULTS Seven trials recruiting 3123 babies were included in the meta-analysis. Four trials recruiting 765 babies compared CPAP with supportive care and three trials (2364 infants) compared CPAP with mechanical ventilation. Apart from a lack of blinding of the intervention all studies were of low risk of bias.In the comparison of CPAP with supportive care there was a reduction in failed treatment (typical risk ratio (RR) 0.66, 95% confidence interval (CI) 0.45 to 0.98; typical risk difference (RD) -0.16, 95% CI -0.34 to 0.02; 4 studies, 765 infants, very low quality evidence). There was no reduction in bronchopulmonary dysplasia (BPD) or mortality.In trials comparing CPAP with assisted ventilation with or without surfactant, CPAP resulted in a small but clinically significant reduction in the incidence of BPD at 36 weeks, (typical RR 0.89, 95% CI 0.79 to 0.99; typical RD -0.04, 95% CI -0.08 to 0.00; 3 studies, 772 infants, moderate-quality evidence); and death or BPD (typical RR 0.89, 95% CI 0.81 to 0.97; typical RD -0.05, 95% CI -0.09 to 0.01; 3 studies, 1042 infants, moderate-quality evidence). There was also a clinically important reduction in the need for mechanical ventilation (typical RR 0.50, 95% CI 0.42 to 0.59; typical RD -0.49, 95% CI -0.59 to -0.39; 2 studies, 760 infants, moderate-quality evidence); and the use of surfactant in the CPAP group (typical RR 0.54, 95% CI 0.40 to 0.73; typical RD -0.41, 95% CI -0.54 to -0.28; 3 studies, 1744 infants, moderate-quality evidence). AUTHORS' CONCLUSIONS There is insufficient evidence to evaluate prophylactic CPAP compared to oxygen therapy and other supportive care. However when compared to mechanical ventilation prophylactic nasal CPAP in very preterm infants reduces the need for mechanical ventilation and surfactant and also reduces the incidence of BPD and death or BPD.

Abstract
BACKGROUND Symphysis fundal height (SFH) measurement is commonly practiced primarily to detect fetal intrauterine growth restriction (IUGR). Undiagnosed IUGR may lead to fetal death as well as increase perinatal mortality and morbidity. OBJECTIVES The objective of this review is to compare SFH measurement with serial ultrasound measurement of fetal parameters or clinical palpation to detect abnormal fetal growth (IUGR and large-for-gestational age), and improving perinatal outcome. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (14 July 2015) and reference lists of retrieved articles. SELECTION CRITERIA Randomised controlled trials including quasi-randomised and cluster-randomised trials involving pregnant women with singleton fetuses at 20 weeks' gestation and above comparing tape measurement of SFH with serial ultrasound measurement of fetal parameters or clinical palpation using anatomical landmarks. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. MAIN RESULTS One trial involving 1639 women was included. It compared SFH measurement with clinical abdominal palpation.There was no difference in the two reported primary outcomes of incidence of small-for-gestational age (risk ratio (RR) 1.32; 95% confidence interval (CI) 0.92 to 1.90, low quality evidence) or perinatal death.(RR 1.25, 95% CI 0.38 to 4.07; participants = 1639, low quality evidence). There were no data on the neonatal detection of large-for-gestational age (variously defined by authors). There was no difference in the reported secondary outcomes of neonatal hypoglycaemia, admission to neonatal nursery, admission to the neonatal nursery for IUGR (low quality evidence), induction of labour and caesarean section (very low quality evidence). The trial did not address the other outcomes specified in the 'Summary of findings' table (intrauterine death; neurodevelopmental outcome in childhood). GRADEpro software was used to assess the quality of evidence, downgrading of evidence was based on including a small single study with unclear risk of bias and a wide confidence interval crossing the line of no effect. AUTHORS' CONCLUSIONS There is insufficient evidence to determine whether SFH measurement is effective in detecting IUGR. We cannot therefore recommended any change of current practice. Further trials are needed.

Abstract
BACKGROUND Respiratory distress syndrome (RDS) is the single most important cause of morbidity and mortality in preterm infants. In infants with progressive respiratory insufficiency, intermittent positive pressure ventilation (IPPV) with surfactant is the standard treatment for the condition, but it is invasive, potentially resulting in airway and lung injury. Continuous distending pressure (CDP) has been used for the prevention and treatment of RDS, as well as for the prevention of apnoea, and in weaning from IPPV. Its use in the treatment of RDS might reduce the need for IPPV and its sequelae. OBJECTIVES To determine the effect of continuous distending pressure (CDP) on the need for IPPV and associated morbidity in spontaneously breathing preterm infants with respiratory distress.Subgroup analyses were planned on the basis of birth weight (> or < 1000 or 1500 g), gestational age (groups divided at about 28 weeks and 32 weeks), methods of application of CDP (i.e. CPAP and CNP), application early versus late in the course of respiratory distress and high versus low pressure CDP and application of CDP in tertiary compared with non-tertiary hospitals, with the need for sensitivity analysis determined by trial quality.At the 2008 update, the objectives were modified to include preterm infants with respiratory failure. SEARCH METHODS We used the standard search strategy of the Neonatal Review Group. This included searches of the Oxford Database of Perinatal Trials, the Cochrane Central Register of Controlled Trials (CENTRAL, 2015 Issue 4), MEDLINE (1966 to 30 April 2015) and EMBASE (1980 to 30 April 2015) with no language restriction, as well as controlled-trials.com, clinicaltrials.gov and the International Clinical Trials Registry Platform of the World Health Organization (WHO). SELECTION CRITERIA All random or quasi-random trials of preterm infants with respiratory distress were eligible. Interventions were continuous distending pressure including continuous positive airway pressure (CPAP) by mask, nasal prong, nasopharyngeal tube or endotracheal tube, or continuous negative pressure (CNP) via a chamber enclosing the thorax and the lower body, compared with spontaneous breathing with oxygen added as necessary. DATA COLLECTION AND ANALYSIS We used standard methods of The Cochrane Collaboration and its Neonatal Review Group, including independent assessment of trial quality and extraction of data by each review author. MAIN RESULTS We included six studies involving 355 infants - two using face mask CPAP, two CNP, one nasal CPAP and one both CNP (for less ill babies) and endotracheal CPAP (for sicker babies). For this update, we included no new trials.Continuous distending pressure (CDP) is associated with lower risk of treatment failure (death or use of assisted ventilation) (typical risk ratio (RR) 0.65, 95% confidence interval (CI) 0.52 to 0.81; typical risk difference (RD) -0.20, 95% CI -0.29 to -0.10; number needed to treat for an additional beneficial outcome (NNTB) 5, 95% CI 4 to 10; six studies; 355 infants), lower overall mortality (typical RR 0.52, 95% CI 0.32 to 0.87; typical RD -0.15, 95% CI -0.26 to -0.04; NNTB 7, 95% CI 4 to 25; six studies; 355 infants) and lower mortality in infants with birth weight above 1500 g (typical RR 0.24, 95% CI 0.07 to 0.84; typical RD -0.28, 95% CI -0.48 to -0.08; NNTB 4, 95% CI 2.00 to 13.00; two studies; 60 infants). Use of CDP is associated with increased risk of pneumothorax (typical RR 2.64, 95% CI 1.39 to 5.04; typical RD 0.10, 95% CI 0.04 to 0.17; number needed to treat for an additional harmful outcome (NNTH) 17, 95% CI 17.00 to 25.00; six studies; 355 infants). We found no difference in bronchopulmonary dysplasia (BPD), defined as oxygen dependency at 28 days (three studies, 260 infants), as well as no difference in outcome at nine to 14 years (one study, 37 infants). AUTHORS' CONCLUSIONS In preterm infants with respiratory distress, the application of CDP as CPAP or CNP is associated with reduced respiratory failure and mortality and an increased rate of pneumothorax. Four out of six of these trials were done in the 1970s. Therefore, the applicability of these results to current practice is difficult to assess. Further research is required to determine the best mode of administration.

Abstract
BACKGROUND Acute otitis media (AOM) is one of the most common infectious diseases in children. It has been reported that 64% of infants have an episode of AOM by the age of six months and 86% by one year. Although most cases of AOM are due to bacterial infection, it is commonly triggered by a viral infection. In most children it is self limiting, but it does carry a risk of complications. Since antibiotic treatment increases the risk of antibiotic resistance, influenza vaccines might be an effective way of reducing this risk by preventing the development of AOM. OBJECTIVES To assess the effectiveness of influenza vaccine in reducing the occurrence of acute otitis media (AOM) in infants and children. SEARCH METHODS We searched CENTRAL (2014, Issue 6), MEDLINE (1946 to July week 1, 2014), EMBASE (2010 to July 2014), CINAHL (1981 to July 2014), LILACS (1982 to July 2014), Web of Science (1955 to July 2014) and reference lists of articles to July 2014. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing influenza vaccine with placebo or no treatment in infants and children aged younger than six years old. We included children of either sex and of any ethnicity, with or without a history of recurrent AOM. DATA COLLECTION AND ANALYSIS Two review authors independently screened studies, assessed trial quality and extracted data. We performed statistical analyses using the random-effects and fixed-effect models and expressed the results as risk ratio (RR), risk difference (RD) and number needed to treat to benefit (NNTB) for dichotomous outcomes, with 95% confidence intervals (CI). MAIN RESULTS We included 10 trials (six trials in high-income countries and four multicentre trials in high-, middle- and low-income countries) involving 16,707 children aged six months to six years. Eight trials recruited participants from a healthcare setting. Nine trials (and all five trials that contributed to the primary outcome) declared funding from vaccine manufacturers. Four trials reported adequate allocation concealment and nine trials reported adequate blinding of participants and personnel. Attrition was low for all trials included in the analysis.The primary outcome showed a small reduction in at least one episode of AOM over at least six months of follow-up (five trials, 4736 participants: RR 0.80, 95% CI 0.67 to 0.96; RD -0.04, 95% CI -0.07 to -0.02; NNTB 25, 95% CI 15 to 50).The subgroup analyses (i.e. number of courses, settings, seasons or types of vaccine administered) showed no differences.There was a reduction in the use of antibiotics in vaccinated children (two trials, 1223 participants: RR 0.70, 95% CI 0.59 to 0.83; RD -0.15, 95% CI -0.30 to -0.00).There was no significant difference in the utilisation of health care for the one trial that provided sufficient information to be included. The use of influenza vaccine resulted in a significant increase in fever (six trials, 10,199 participants: RR 1.15, 95% CI 1.06 to 1.24; RD 0.02, 95% CI -0.00 to 0.05) and rhinorrhoea (six trials, 10,563 children: RR 1.17, 95% CI 1.07 to 1.29; RD 0.09, 95% CI 0.01 to 0.16) but no difference in pharyngitis. No major adverse events were reported.Compared to the protocol, the review included a subgroup analysis of AOM episodes by season, and changed the types of influenza vaccine from a secondary outcome to a subgroup analysis. AUTHORS' CONCLUSIONS Influenza vaccine results in a small reduction in AOM. The observed reduction with the use of antibiotics needs to be considered in the light of current recommended practices aimed at avoiding antibiotic overuse. Safety data from these trials are limited. The benefits may not justify the use of influenza vaccine without taking into account the vaccine efficacy in reducing influenza and safety data. The quality of the evidence was high to moderate. Additional research is needed.

Abstract
BACKGROUND About 5% of schoolchildren have a specific learning disorder, defined as an unexpected failure to acquire adequate abilities in reading, writing or mathematic skills not as a result of reduced intellectual ability, inadequate teaching or social deprivation. Of these, 80% are reading disorders. Polyunsaturated fatty acids (PUFAs), in particular omega-3 and omega-6 fatty acids, which are found abundantly in the brain and retina are important for learning. Some children with specific learning disorders have been found to be deficient in these PUFAs, and it is argued that supplementation of PUFAs may help these children improve their learning abilities. OBJECTIVES To assess the effects of polyunsaturated fatty acids (PUFAs) supplementation for children with specific learning disorders, on learning outcomes. SEARCH METHODS We searched the following databases in April 2012: CENTRAL (2012, Issue 4), MEDLINE (1948 to April Week 2 2012), EMBASE (1980 to 2012 Week 16), PsycINFO (1806 to April 2012), ERIC (1966 to April 2012), Science Citation Index (1970 to 20 April 2012), Social Science Citation Index (1970 to 20 April 2012), Conference Proceedings Citation Index-Science (1970 to 20 April 2012), Conference Proceedings Citation Index-Social Sciences and Humanites (1970 to 20 April 2012), Cochrane Database of Systematic Reviews (2012, Issue 4), DARE (2012, Issue 2) , ZETOC (24 April 2012) and WorldCat (24 April 2012). We searched the WHO International Clinical Trials Registry Platform and ClinicalTrials.gov on 24 April 2012. We also searched the reference lists of relevant articles identified by the searches. SELECTION CRITERIA Randomised or quasi-randomised controlled trials comparing polyunsaturated fatty acids (PUFAs) with placebo or no treatment in children aged below 18 years with specific learning disabilities diagnosed using DSM-IV, ICD-10 or equivalent criteria. We intended to include participants with co-existing developmental disorders such as attention deficit hyperactivity disorder (ADHD) or autism. DATA COLLECTION AND ANALYSIS Two authors (ML and KH) independently screened the titles and abstracts of the search results and eliminated all studies that did not meet the inclusion criteria. Authors were contacted for missing information and clarifications when needed. MAIN RESULTS We did not find any studies suitable for inclusion in the review. One study is awaiting classification as we were unable to get any information from the study author. AUTHORS' CONCLUSIONS There is insufficient evidence to draw any conclusion about the use of PUFAs for children with specific learning disorders. There is a need for well designed randomised studies to support or refute the use of PUFAs in this group of children.

Abstract
BACKGROUND Separate care for a new mother and infant may affect the duration of breastfeeding, breastfeeding behaviour and may have an adverse effect on neonatal and maternal outcomes. OBJECTIVES To assess the effect of mother-infant separation versus rooming-in on the duration of breastfeeding (exclusive and total duration of breastfeeding). SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 June 2012). SELECTION CRITERIA Randomised or quasi-randomised controlled trials (RCTs) investigating the effect of separate mother-infant care versus rooming-in after hospital birth or at home on the duration of breastfeeding, proportion of breastfeeding at six months and adverse neonatal and maternal outcomes. DATA COLLECTION AND ANALYSIS Two review authors independently assessed the studies for inclusion and assessed trial quality. Two review authors extracted data. Data were checked for accuracy. MAIN RESULTS There were 23 reports from 19 potential trials identified. After assessment, one trial (involving 176 women) met our inclusion criteria.One trial reported an overall median duration of any breastfeeding of four months. Exclusive breastfeeding before discharge from hospital (at day four postpartum) was significantly lower in the separate care group compared with the rooming-in group (risk ratio (RR) 0.58; 95% CI 0.42 to 0.81; one trial, 141 women). AUTHORS' CONCLUSIONS We found little evidence to support or refute the practice of mother-infant separation versus rooming-in. Therefore, we see no reason to practise it. We recommend a well designed RCT to investigate full mother-infant rooming-in versus partial rooming-in or separate care on all of the primary and secondary outcomes suggested.

Abstract
BACKGROUND Breastfeeding (BF) is well recognised as the best food for infants. The impact of antenatal BF education on the duration of BF has not been evaluated. OBJECTIVES To evaluate the effectiveness of antenatal BF education for increasing BF initiation and duration. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (2 December 2011), CENTRAL (The Cochrane Library 2011, Issue 11), MEDLINE (1966 to 30 November 2011) and Scopus (January 1985 to 30 November 2011). We contacted experts and searched reference lists of retrieved articles. SELECTION CRITERIA All identified published, unpublished and ongoing randomised controlled trials (RCTs) assessing the effect of formal antenatal BF education or comparing two different methods of formal antenatal BF education, on duration of BF. We excluded RCTs that also included intrapartum or postpartum BF education. DATA COLLECTION AND ANALYSIS We assessed all potential studies identified as a result of the search strategy. Two review authors extracted data from each included study using the agreed form and assessed risk of bias. We resolved discrepancies through discussion. MAIN RESULTS We included 19 studies with 8506 women in the review and 16 studies involving 8262 women contributed data to the analyses. We did not carry out any meta-analysis because there was only one study for each comparison.Five studies compared a single method of BF education with routine care. Peer counselling significantly increased BF initiation.Three studies compared one form of BF education versus another. No intervention was significantly more effective than another intervention in increasing initiation or duration of BF.Seven studies compared multiple methods versus a single method of BF education. Combined BF educational interventions were not significantly better than a single intervention in initiating or increasing BF duration. However, in one trial a combined BF education significantly reduced nipple pain and trauma.One study compared different combinations of interventions. There was a marginally significant increase in exclusive BF at six months in women receiving a booklet plus video plus lactation consultation (LC) compared with the booklet plus video only.Two studies compared multiple methods of BF education versus routine care. The combination of BF booklet plus video plus LC was significantly better than routine care for exclusive BF at three months. AUTHORS' CONCLUSIONS Because there were significant methodological limitations and the observed effect sizes were small, it is not appropriate to recommend any specific antenatal BF education.There is an urgent need to conduct RCTs with adequate power to evaluate the effectiveness of antenatal BF education.

Abstract
BACKGROUND To successfully initiate and maintain breastfeeding for a longer duration, the World Health Organization's Ten Steps to Successful Breastfeeding recommends total avoidance of artificial teats or pacifiers for breastfeeding infants. Offering the pacifier instead of the breast to calm the infant may lead to less frequent episodes of breastfeeding and as a consequence may reduce breast milk production and shorten duration of breastfeeding; however, this remains unclear. OBJECTIVES To assess the effect of unrestricted versus restricted pacifier use in healthy full-term newborns whose mothers have initiated breastfeeding and intend to exclusively breastfeed, on the duration of breastfeeding, other breastfeeding outcomes and infant health. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (14 March 2012). SELECTION CRITERIA Randomised and quasi-randomised controlled trials comparing unrestricted versus restricted pacifier use in healthy full-term newborns who have initiated breastfeeding regardless of whether they were born at home or in the hospital. DATA COLLECTION AND ANALYSIS Two authors independently assessed the studies for inclusion, assessed risk of bias and carried out data extraction. Data were checked for accuracy. MAIN RESULTS We found three trials (involving 1915 babies) for inclusion in the review but have included only two trials (involving 1302 healthy full-term breastfeeding infants) in the analysis. Meta-analysis of the two combined studies showed that pacifier use in healthy breastfeeding infants had no significant effect on the proportion of infants exclusively breastfed at three months (risk ratio (RR) 0.99; 95% confidence interval (CI) 0.93 to 1.05), and at four months of age (RR 0.99; 95% CI 0.92 to 1.06) and also had no effect on the proportion of infants partially breastfed at three months (RR 1.00; 95% CI 0.98 to 1.13), and at 4 months of age (RR 1.01; 95% CI 0.98 to 1.03). AUTHORS' CONCLUSIONS Pacifier use in healthy term breastfeeding infants, started from birth or after lactation is established, did not significantly affect the prevalence or duration of exclusive and partial breastfeeding up to four months of age. However, evidence to assess the short-term breastfeeding difficulties faced by mothers and long-term effect of pacifiers on infants' health is lacking.

Abstract
We conducted a before and after study to determine whether an educational intervention to build capacity in the understanding and implementation of evidence could result in improved outcomes for mothers and babies in obstetric and neonatal units of two Malaysian hospitals. Twelve practices and thirteen associated outcomes were selected based on clear evidence from the Cochrane Library. There were significant improvements in most practices with little change in outcomes. In the short term a targeted intervention to build capacity in the understanding and implementation of evidence results in an improved process of care without adverse outcomes.

Meta-analysis of the two combined studies showed that pacifier use in healthy breastfeeding infants had no significant effect on the proportion of infants exclusively breastfed at three months (risk ratio (RR) 1.00; 95% confidence interval (CI) 0.95 to 1.06), and at four months of age (RR 0.99; 95% CI 0.92 to 1.06) and also had no effect on the proportion of infants partially breastfed at three months (RR 1.00; 95% CI 0.97 to 1.02), and at 4 months of age (RR 1.01; 95% CI 0.98 to 1.03). AUTHORS' CONCLUSIONS Pacifier use in healthy term breastfeeding infants, started from birth or after lactation is established, did not significantly affect the prevalence or duration of exclusive and partial breastfeeding up to four months of age. However, evidence to assess the short-term breastfeeding difficulties faced by mothers and long-term effect of pacifiers on infants' health is lacking.
