Maternal factors associated with low birth weight in public hospitals of Mekelle city, Ethiopia: a case-control study

BACKGROUND

Mothers in low socio-economic conditions frequently have low birth weight infants. Inaddition Physically demanding work during pregnancy also contributes to poor fetal growth. During gestation a woman needs balanced nutrition for a healthy outcome. Women with inadequate nutritional status at conception are at greater risk of aquiring disease; their health usually depends on the availability and consumption of balanced diet, and therefore they are unlikely to be able to resist with their high nutrient needs during pregnancy. Therefore, the main purpose of this study was to assess the maternal risk factors associated low birth weight in public hospitals of Mekelle city, Tigray North Ethiopia, 2017/2018.

METHODS

Un-matched case-control study design was conducted among women who delivered in public hospitals of Mekelle city. Data was collected using a structured questionnaire through interview, direct physical assessment and medical record review of mothers. Sample size was calculated by Epi-info version 7.0 to get a final sample size of 381(cases = 127 and controls = 254). SPSS version 20 was used for analysis. Bivariate and multivariate logistic regression analysis was used to determine the effect of the independent variables on birth weight. Presence of significant association was determined using OR with its 95%CI. A P value of less than 0.05 was considered to declare statistical significance. Table, graphs and texts were used to present the data.

RESULT

Most of the mothers (70.1% cases and 43.7% controls) were housewives. This study showed that maternal age ≤ 20 years (AOR = 6.42(95% CI = (1.93-21.42)), ANC follow up (AOR = 3.73(95%CI (1.5-9.24)), History of medical illness (AOR = 14.56(95% CI (3.69-57.45), Iron folate intake (AOR = 21.56(95%CI (6.54-71.14)), Maternal height less than 150 cm (AOR = 9.27(95%CI 3.45-24.89)) and Pregnancy weight gain (AOR = 4.93(95%CI = 1.8-13.48) were significant predictors of low birth weight.

CONCLUSION

The study suggests that inadequate ANC follow-up, preterm birth and history of chronic medical illness, maternal height, pregnancy weight gain, and Iron intake were. Were significant predictors of low birth weight. Health professionals should screen and consulate pregnant mothers who are at risk of having infants with LBW and ensure that women have access to essential health information on the causes of low birth weight.

Determinants of Women's Drug Use During Pregnancy: Perspectives from a Qualitative Study

INTRODUCTION

Drug use during pregnancy can have negative effects on maternal and child health. However, there is a dearth of data regarding drug use among pregnant women in Kenya, where illicit drug use is on the rise. In this paper, we report factors influencing women's decisions to use drugs during pregnancy.

METHODS

In 2015, we conducted in-depth interviews and focus group discussions with 45 women who inject drugs and five key stakeholders involved in provision of services to people who use drugs in coastal Kenya. Inductive thematic analysis was conducted to draw out themes related to key determinants of drug use during pregnancy.

RESULTS

Four key themes emerged outlining determinants of drug use during pregnancy: (i) the use of drugs to cope with the stress of unexpected pregnancy, (ii) the continued drug use during pregnancy to manage withdrawal, (iii) the dual effect of pregnancy on drug use either as a facilitator or as a moderator of drug use, and (iv) the role of male intimate partner in influencing women's drug use during pregnancy.

CONCLUSION

Our paper reports women's drug use during pregnancy and the factors influencing this phenomenon. To safeguard the health and well-being of pregnant women and their unborn children, there is a need for education and awareness raising, implementing couple-based harm reduction approaches to leverage on positive male influences, improving availability of drug treatment, and provision of family planning interventions for women who use drugs.

Systematic review of Group B Streptococcal capsular types, sequence types and surface proteins as potential vaccine candidates

•

Most comprehensive review of Group B Streptococcal serotypes through 2018.

•

First systematic review of Group B Streptococcal strain type and protein data.

•

Theoretically candidate vaccines may protect against 93-99% disease-causing strains.

•

More studies on GBS strains in low- and middle-income countries are needed.

Background

21 million pregnant women worldwide (18%) are estimated to carry Group B Streptococcus (GBS), which is a risk for invasive disease in newborns, pregnant women, and stillbirths. Adults ≥ 60 years or with underlying health conditions are also vulnerable to invasive GBS disease. We undertook systematic reviews on GBS organism characteristics including: capsular polysaccharide (serotype), sequence type (multi-locus sequence types (MLST)), and virulence proteins. We synthesised data by at-risk populations, to inform vaccine development.

Methods

We conducted systematic reviews and meta-analyses to estimate proportions of GBS serotypes for at risk populations: maternal colonisation, invasive disease in pregnant women, stillbirths, infants 0–90 days age, and older adults (≥60 years). We considered regional variation and time trends (2001–2018). For these at-risk population groups, we summarised reported MLST and surface proteins.

Results

Based on 198 studies (29247isolates), 93–99% of GBS isolates were serotypes Ia, Ib, II, III, IV and V. Regional variation is likely, but data gaps are apparent, even for maternal colonisation which has most data. Serotype III dominates for infant invasive disease (60%) and GBS-associated stillbirths (41%). ST17 accounted for a high proportion of infant invasive disease (41%; 95%CI: 35–47) and was found almost exclusively in serotype III strains, less present in maternal colonisation (9%; 95%CI:6–13),(4%; 95%CI:0–11) infant colonisation, and adult invasive disease (4%, 95%CI:2–6). Percentages of strains with at least one of alp 1, alp2/3, alpha C or Rib surface protein targets were 87% of maternal colonisation, 97% infant colonisation, 93% infant disease and 99% adult invasive disease. At least one of three pilus islands proteins were reported in all strains.

Discussion

A hexavalent vaccine (serotypes Ia, Ib, II, III, IV and V) might provide comprehensive cover for all at-risk populations. Surveillance of circulating, disease-causing target proteins is useful to inform vaccines not targeting capsular polysaccharide. Addressing data gaps especially by world region and some at-risk populations (notably stillbirths) is fundamental to evidence-based decision-making during vaccine design.

The association between analgesic drug use in pregnancy and neurodevelopmental disorders: protocol for an umbrella review

BACKGROUND

Maternal prenatal health has been shown to be an important influence on children's developmental outcomes, which has led to an increased emphasis on providing more information to support clinical decisions in pregnancy. Several systematic reviews suggest that analgesic drug use during pregnancy may have neurodisruptive properties. However, no firm conclusions have yet been drawn on the associations between prenatal analgesic drug use and children's long-term development of neurodevelopmental disorders such as autism spectrum disorder (ASD) or attention deficit hyperactivity disorder (ADHD). Therefore, an umbrella review is proposed for the purpose of examining the associations between maternal analgesic drug use during pregnancy and diagnoses of neurodevelopmental disorders.

METHODS

Included systematic reviews will consist of studies examining the effect of maternal prenatal analgesic drug use, specifically ibuprofen, acetaminophen, aspirin, naproxen, diclofenac, and ketoprofen, on children's neurodevelopmental disorder status. Examined drugs were restricted to those readily accessible and frequently used by pregnant women, and with characteristics that allow them to cross the placenta and directly affect fetal development. Outcomes will be restricted to formal clinical diagnoses of ASD and/or ADHD. Two reviewers will independently identify eligible reviews from six databases (e.g., PubMed, EMBASE, PsychINFO) from inception dates of databases to the date of data extraction, and conduct manual searches of reference lists, consultation with field experts, and scan of pre-print archives. Extracted data will also include short qualitative summaries by both reviewers. As part of quality assessment, a standardized measurement tool to assess systematic reviews (AMSTAR 2) will be used. A narrative synthesis is proposed to integrate findings from different, potentially methodologically heterogeneous, studies.

DISCUSSION

This umbrella review of associations between maternal prenatal use of analgesic drugs and children's neurodevelopmental disorders could allow for firmer conclusions to be drawn through the synthesis of all relevant published research. The synthesis of findings using high-quality evidence could provide more accurate healthcare information on the long-term effects of analgesic drugs on neurodevelopment, to better guide future clinical decisions during pregnancy. This review will also allow gaps and methodological differences in the literature to be identified, informing recommendations for future research.

The impact of educational attainment on the occurrence of gestational diabetes mellitus in two successive pregnancies of Finnish primiparous women: a population-based cohort study

AIMS

To assess the impact of educational attainment on the occurrence and recurrence of gestational diabetes mellitus (GDM) in two successive pregnancies in primiparous women.

METHODS

This is a population-based observational cohort study including all 2347 Finnish women without previously diagnosed diabetes, aged ≥ 20 years from the city of Vantaa, Finland, who gave birth to their first and second child between 2009 and 2015. National registries provided data on study participants. We divided the population into four groups according to the presence of GDM in the two pregnancies (GDM-/-, n = 1820; GDM-/+, n = 223; GDM+/-, n = 113; GDM+/+, n = 191).

RESULTS

The occurrence of GDM in the first pregnancy was 13.0% (n = 304) and 17.6% (n = 414) in the second. The recurrence rate of GDM was 62.8%. The four groups did not differ in relation to educational attainment (p = 0.11). In multinomial regression analysis, educational attainment protected from GDM in the second pregnancy [relative risk ratio 0.93 (95% confidence interval (CI) 0.86-0.99) per year of schooling for being GDM-/+ compared with GDM-/-]. In multivariate logistics models, prepregnancy body mass index at the first pregnancy [odds ratio (OR) 1.53 per 1-standard deviation (SD) (95% CI 1.22-1.91)], first-born birth weight z-score [OR 1.30 per 1-SD (95% CI 1.00-1.67)], and inter-pregnancy weight change [OR 1.66 per 1-SD (95% CI 1.27-2.16)], but not educational attainment, predicted recurrence of GDM.

CONCLUSIONS

The recurrence rate of GDM was high. Education protected from novel GDM in the second pregnancy, but was not associated with GDM recurrence.

Periconceptional stressors and social support and risk for adverse birth outcomes

Background

The prevalence of preterm birth and low birth weight has been increasing slightly in recent years. A few studies have suggested that psychosocial stress during pregnancy may increase risk for these adverse birth outcomes. To extend those observations, we analyzed various major life event stressors separately and cumulatively as potential risk factors for preterm birth and low birth weight using granular categories of each outcome in a large, population-based study. Additionally, we assessed if greater social support buffered any effects.

Methods

Data were from a nested prevalence study of 4395 women in the National Birth Defects Prevention Study who delivered live-born non-malformed infants (controls) between 2006 and 2011. Participants completed a standardized, computer-assisted interview between 6 weeks and 24 months after delivery that included questions on stress and social support from 3 months before pregnancy to the 3rd month of pregnancy. Cumulative stress and support indices were also calculated. Preterm birth was divided into “early preterm” (< 32 weeks), “late preterm” (32–36 weeks) and “term.” Low birthweight was divided into “very low birth weight” (< 1500 g), “low birth weight” (1500–2499 g) and “normal birth weight” (≥2500 g). Relative risks and 95% confidence intervals (95% CI) were calculated using Poisson regression.

Results

For women reporting relationship difficulties, there was a suggestive risk of early preterm birth (RR: 1.9, 95%CI: 0.9–3.9) and very low birthweight (RR: 2.0, 95%CI: 0.9–4.4). For women reporting that they or someone close to them were victims of abuse, violence, or crime, there was an increased risk of low birthweight (RR: 1.8, 95%CI: 1.1–2.7) and late preterm birth (RR: 1.5, 95%CI: 1.0–2.2). There were no strong associations observed between social support questions and the various outcomes.

Conclusions

Our results add some support to prior evidence that certain stressors may be associated with increase selected adverse birth outcomes risk. We did not find strong evidence that social support buffered the observed risks in our study.

A Phenotype of Childhood Autism Is Associated with Preexisting Maternal Anxiety and Depression

This study explored whether ASD phenotypes in the child were associated with a history of anxiety or depression in the mother. We hypothesized that an ASD profile in children characterized by mild delays and increased rates of dysregulation would be associated with preexisting maternal anxiety or depression. Participants were 672 preschool children with ASD and their mothers. Children were classified as ASD after a comprehensive developmental evaluation. Mothers reported whether a healthcare provider ever diagnosed them with anxiety or depression before the birth of their child. Four child ASD phenotypes were derived from latent class analysis: Mild Language Delay with Cognitive Rigidity (Type 1), Significant Developmental Delay with Repetitive Motor Behaviors (Type 2), General Developmental Delay (Type 3), and Mild Language and Motor Delay with Dysregulation (i.e., aggression, anxiety, depression, emotional reactivity, inattention, somatic complaints, and sleep problems) (Type 4). Type 2 ASD served as the referent category in statistical analyses. Results showed that 22.6% of mothers reported a diagnosis of anxiety or depression before the birth of their child. Maternal anxiety or depression was associated with 2.7 times the odds (95% confidence interval: 1.4, 5.3) of Type 4 or Dysregulated ASD in the child; maternal anxiety and depression was associated with 4.4 times the odds (95% confidence interval: 1.4, 14.0) of Type 4 or Dysregulated ASD in the child. Our findings suggest an association between Dysregulated ASD in the child and anxiety and depression in the mother. These findings can enhance screening methods and inform future research efforts.

Placental microRNAs: Responders to environmental chemicals and mediators of pathophysiology of the human placenta

MicroRNAs (miRNAs) are epigenetic modifiers that play an important role in the regulation of the expression of genes across the genome. miRNAs are expressed in the placenta as well as other organs, and are involved in several biological processes including the regulation of trophoblast differentiation, migration, invasion, proliferation, apoptosis, angiogenesis and cellular metabolism. Related to their role in disease process, miRNAs have been shown to be differentially expressed between normal placentas and placentas obtained from women with pregnancy/health complications such as preeclampsia, gestational diabetes mellitus, and obesity. This dysregulation indicates that miRNAs in the placenta likely play important roles in the pathogenesis of diseases during pregnancy. Furthermore, miRNAs in the placenta are susceptible to altered expression in relation to exposure to environmental toxicants. With relevance to the placenta, the dysregulation of miRNAs in both placenta and blood has been associated with maternal exposures to several toxicants. In this review, we provide a summary of miRNAs that have been assessed in the context of human pregnancy-related diseases and in relation to exposure to environmental toxicants in the placenta. Where data are available, miRNAs are discussed in their context as biomarkers of exposure and/or disease, with comparisons made across-tissue types, and conservation across studies detailed.

Perinatal listeriosis patients treated at a maternity hospital in Beijing, China, from 2013-2018

Background

Listeriosis is a rare but severe foodborne infectious disease. Perinatal listeriosis is often associated with septicemia, central nervous system (CNS) infection, and serious adverse pregnancy outcomes (miscarriage and neonate death). Here we report the characteristics and outcomes of perinatal listeriosis cases treated over 6 years at Beijing Obstetrics and Gynecology Hospital (BOGH), the largest maternity hospital in China.

Methods

We retrospectively reviewed the records of laboratory-confirmed, pregnancy-associated listeriosis cases treated from January 1, 2013 to December 31, 2018. The clinical manifestations, laboratory results, perinatal complications and outcomes (post-natal follow-up of 6 months) were investigated.

Results

In BOGH, 12 perinatal listeriosis cases were diagnosed based on Listeria monocytogenes positive culture, including 10 single pregnancies and 2 twin pregnancies. The corresponding incidence of pregnancy-associated listeriosis was 13.7/100,000 deliveries. Among those cases, four pregnant women and four newborns had septicemia, and two of the neonates with septicemia also suffered CNS infection. All the maternal patients recovered. Two inevitable miscarriages and four fetal stillbirths occurred. Of the eight delivered newborns, six survived, and two died within 2 days from birth. None of the survivors had neurological sequelae during a 6-month follow-up. The overall feto-neonatal fatality rate was 57.1%; notably, this rate was 100% for infections occurring during the second trimester of pregnancy and only 14.3% for those occurring in the third trimester.

Conclusions

Perinatal listeriosis is associated with high feto-neonatal mortality, and thus, a public health concern. Additional large-scale studies are needed to strengthen the epidemiological understanding of listeriosis in China.

Prenatal developmental toxicity study of an alkaloid-free Ageratum conyzoides extract powder in rats by oral administration

A prenatal developmental toxicological study was conducted to evaluate the safety of an alkaloid-free Ageratum conyzoides extract powder administration on pregnant female Wistar rats and on the development of the conceptus in accordance with OECD test guideline (no. 414). Pyrrolizidine alkaloids (PAs) naturally present in A. conyzoides have been shown to induce toxicity in past studies, particularly towards hepatic cells. Therefore our test item preparation of A.conyzoides extract (aerial part of the plant) consisted of the removal of PAs. There were no treatment related adverse effects found during maternal examinations (body weights, food consumption, numbers of pregnant and non-pregnant female rats, endocrine evaluation, gravid uterine weights, and number of corpora lutea), maternal/fetal examinations (numbers of implantation sites, pre-and post-implantation loss (%), dead and live fetuses (%), resorption sites), or fetal examinations (litter size and weights, number of fetuses, sex ratio, or external, visceral, and skeletal variations and malformations) in the Ageratum conyzoides extract powder groups at doses of 500, 1000 and 2000 mg/kw bw/day compared to vehicle control group. The no observed adverse effect level (NOAEL) determined for both maternal and developmental toxicity was 2000 mg/kg bw/day, which was the highest dose tested.

Labour and delivery ward register data availability, quality, and utility - Every Newborn - birth indicators research tracking in hospitals (EN-BIRTH) study baseline analysis in three countries

BACKGROUND

Countries with the highest burden of maternal and newborn deaths and stillbirths often have little information on these deaths. Since over 81% of births worldwide now occur in facilities, using routine facility data could reduce this data gap. We assessed the availability, quality, and utility of routine labour and delivery ward register data in five hospitals in Bangladesh, Nepal, and Tanzania. This paper forms the baseline register assessment for the Every Newborn-Birth Indicators Research Tracking in Hospitals (EN-BIRTH) study.

METHODS

We extracted 21 data elements from routine hospital labour ward registers, useful to calculate selected maternal and newborn health (MNH) indicators. The study sites were five public hospitals during a one-year period (2016-17). We measured 1) availability: completeness of data elements by register design, 2) data quality: implausibility, internal consistency, and heaping of birthweight and explored 3) utility by calculating selected MNH indicators using the available data.

RESULTS

Data were extracted for 20,075 births. Register design was different between the five hospitals with 10-17 of the 21 selected MNH data elements available. More data were available for health outcomes than interventions. Nearly all available data elements were > 95% complete in four of the five hospitals and implausible values were rare. Data elements captured in specific columns were 85.2% highly complete compared to 25.0% captured in non-specific columns. Birthweight data were less complete for stillbirths than live births at two hospitals, and significant heaping was found in all sites, especially at 2500g and 3000g. All five hospitals recorded count data required to calculate impact indicators including; stillbirth rate, low birthweight rate, Caesarean section rate, and mortality rates.

CONCLUSIONS

Data needed to calculate MNH indicators are mostly available and highly complete in EN-BIRTH study hospital routine labour ward registers in Bangladesh, Nepal and Tanzania. Register designs need to include interventions for coverage measurement. There is potential to improve data quality if Health Management Information Systems utilization with feedback loops can be strengthened. Routine health facility data could contribute to reduce the coverage and impact data gap around the time of birth.

Linking Mother and Offspring Depressive Symptoms: The mediating role of child appearance contingent self-worth

BACKGROUND

Adolescents exposed to maternal depression are more vulnerable to depressive symptoms. Less is known on the mediating role of children's self-worth construction processes, particularly those related to physical appearance. This study proposes and tests appearance contingent self-worth (ACSW) as a mediator linking depressive symptoms across generations.

METHODS

Our sample included 1,420 participants of the Great Smoky Mountain Study. Offspring depressive symptoms were prospectively assessed with DSM-IV for both the adolescent period (13-16) and adulthood period (19-26). Maternal depression was screened with the Short Mood and Feelings Questionnaire when the child was 13-16 years old. We used gender-stratified structural equation model in which offspring ACSW in adolescence and adulthood were specified as mediators linking maternal depression and offspring depressive symptoms in adolescence and adulthood, respectively. Mediation was tested using bias-corrected bootstrapped standard errors.

RESULTS

ACSW is associated with higher levels of depressive symptoms in both adolescent and adult females and males, but the link between maternal depressive symptoms and ACSW is only significant among females. ACSW partially mediates the effects of maternal depressive symptoms on adolescent and adult depressive symptoms in girls.

LIMITATIONS

Measurement of maternal depression was not based on diagnosis. Generalizability is limited due to the regional sample.

CONCLUSION

Our findings provide evidence that daughters of depressed mothers may stake their self-worth on body image, which may partially explain some of their higher susceptibility to depression.

The impact of prenatal exposure to PM2.5 on childhood asthma and wheezing: a meta-analysis of observational studies

With the accelerated pace of economic development and modernization, air pollution has become one of the most focused public health problems. However, the impact of particulate matter exposure during pregnancy on childhood asthma and wheezing remains controversial. We performed this meta-analysis to explore the relationship between prenatal exposure to PM_2.5 and childhood asthma and wheezing. Candidate papers were searched on PubMed, Web of Science, Embase, and Cochrane Library before July 15, 2019. The main characteristics of the included studies were extracted, and the quality was evaluated by the Newcastle-Ottawa Scale (NOS). A sensitivity analysis was performed to assess the impact of individual studies on the combined effects. The Egger and Begg tests were conducted to examine the publication bias. Nine studies were included in the final analysis. Prenatal exposure to PM_2.5 significantly increased the risk of childhood asthma and wheezing (OR = 1.06, 95% CI 1.02-1.11; per 5 μg/m³). Maternal exposure was more strongly related to childhood asthma and wheezing before age 3 (OR = 1.15, 95% CI 1.00-1.31; per 5 μg/m³) than after (OR = 1.04, 95% CI 1.00-1.09; per 5 μg/m³). Children in developed countries showed more severe effects (OR = 1.14, 95% CI 1.02-1.27; per 5 μg/m³). Children who were born to mothers with higher levels of prenatal exposure were at higher risk of asthma and wheezing (OR = 1.07, 95% CI 1.02-1.13; per 5 μg/m³). This meta-analysis indicated that the impact of PM_2.5 on childhood asthma and wheezing begins as early as utero, so regulating pollutant emission standards and strengthening prenatal protection are crucial to maternal and child health.

A review of the costs of delivering maternal immunisation during pregnancy

Background

Routine maternal immunisation against influenza and pertussis are recommended by the WHO to protect mother and child, and new vaccines are under development. Introducing maternal vaccines into national programmes requires an understanding of vaccine delivery costs – particularly in low resource settings.

Methods

We searched Medline, Embase, Econlit, and Global Health for studies reporting costs of delivering vaccination during pregnancy but excluded studies that did not separate the vaccine purchase price. Extracted costs were inflated and converted to 2018 US dollars.

Results

Sixteen studies were included, of which two used primary data to estimate vaccine delivery costs. Costs per dose ranged from $0.55 to $0.64 in low-income countries, from $1.25 to $6.55 for middle-income countries, and from $5.76 to $39.87 in high-income countries.

Conclusions

More research is needed on the costs of delivering maternal immunisation during pregnancy, and of integrating vaccine delivery into existing programmes of antenatal care especially in low and middle-income countries.

Male involvement in reproductive, maternal, newborn, and child health: evaluating gaps between policy and practice in Uganda

INTRODUCTION

Male involvement in maternal and child health is a practice wherein fathers and male community members actively participate in caring for women and supporting their family to access better health services. There is positive association between male involvement and better maternal and child health outcomes. However, the practice is not always practiced optimally, especially in low- and middle-income countries, where women may not have access to economic resources and decision-making power.

AIM

This study investigates how key stakeholders within the health system in Uganda engage with the 'male involvement' agenda and implement related policies. We also analyzed men's perceptions of male involvement initiatives, and how these are influenced by different political, economic, and organizational factors.

METHODOLOGY

This is a qualitative study utilizing data from 17 in-depth interviews and two focus group discussions conducted in Kasese and Kampala, Uganda. Study participants included men involved in a maternal health project, their wives, and individuals and organizations working to improve male involvement; all purposively selected.

RESULT

Through thematic analysis, four major themes were identified: 'gaps between policy and practice', 'resources and skills', 'inadequate participation by key actors', and 'types of dissemination'. These themes represent the barriers to effective implementation of male involvement policies. Most health workers interviewed have not been adequately trained to provide male-friendly services or to mobilize men. Interventions are highly dependent on external aid and support, which in turn renders them unsustainable. Furthermore, community and religious leaders, and men themselves, are often left out of the design and management of male involvement interventions. Finally, communication and feedback mechanisms were found to be inadequate.

CONCLUSION

To enable sustainable behavior change, we suggest a 'bottom-up' approach to male involvement that emphasizes solutions developed by or in tandem with community members, specifically, fathers and community leaders who are privy to the social norms, structures, and challenges of the community.

Maternal and perinatal outcomes and pharmacological management of Covid-19 infection in pregnancy: a systematic review protocol

BACKGROUND

Over 4.2 million confirmed cases and more than 285,000 deaths, COVID-19 pandemic continues to harm significant number of people worldwide. Several studies have reported the impact of COVID-19 in general population; however, there is scarcity of information related to pharmacological management and maternal and perinatal outcomes during the pandemic. Altered physiological, anatomical, and immunological response during pregnancy makes it more susceptible to infections. Furthermore, during pregnancy, a woman undergoes multiple interactions with the health care system that increases her chance of getting infected; therefore, managing pregnant population presents a unique challenge.

RESEARCH QUESTIONS

This systematic review seeks to answer the following questions in relation to COVID-19: What are the different clinical characteristics presented in maternal and perinatal population? What are the different maternal and perinatal outcome measures reported? What are the distinct therapeutic interventions reported to treat COVID-19? Is it safe to use "medications" used in the treatment of COVID-19 during antenatal, perinatal, postnatal, and breastfeeding?

METHOD

The search will follow a comprehensive, sequential three step search strategy. Several databases relevant to COVID-19 and its impact on pregnancy including Medline, CINAHL, and LitCovid will be searched from the inception of the disease until the completion of data collection. The quality of this search strategy will be assessed using Peer Review of Electronic Search Strategies Evidence-Based Checklist (PRESS EBC). An eligibility form will be developed for a transparent screening and inclusion/exclusion of studies. All studies will be sent to RefWorks, and abstraction will be independently performed by two researchers. Risk of bias will be assessed using Cochrane Risk of Bias tool for randomized controlled trials, Newcastle-Ottawa Quality Assessment Scale for non-randomized studies, and for case reports, Murad et al. tool will be used. Decision to conduct meta-analysis will be based on several factors including homogeneity and outcome measures reported; otherwise, a narrative synthesis will be deemed appropriate.

DISCUSSION

This systematic review will summarize the existing data on effect of COVID-19 on maternal and perinatal population. Furthermore, to the best of our knowledge, this is the first systematic review addressing therapeutic management and safety of medicines to treat COVID-19 during pregnancy and breastfeeding.

SYSTEMATIC REVIEW REGISTRATION

This systematic review has been registered and published with Prospero ( CRD42020172773 ).

Association of anthropometric measures across the life-course with refractive error and ocular biometry at age 15 years

Background

A recent Genome-wide association meta-analysis (GWAS) of refractive error reported shared genetics with anthropometric traits such as height, BMI and obesity. To explore a potential relationship with refractive error and ocular structure we performed a life-course analysis including both maternal and child characteristics using data from the Avon Longitudinal Study of Parents and Children cohort.

Methods

Measures collected across the life-course were analysed to explore the association of height, weight, and BMI with refractive error and ocular biometric measures at age 15 years from 1613children. The outcome measures were the mean spherical equivalent (MSE) of refractive error (dioptres), axial length (AXL; mm), and radius of corneal curvature (RCC; mm). Potential confounding variables; maternal age at conception, maternal education level, parental socio-economic status, gestational age, breast-feeding, and gender were adjusted for within each multi-variable model.

Results

Maternal height was positively associated with teenage AXL (0.010 mm; 95% CI: 0.003, 0.017) and RCC (0.005 mm; 95% CI: 0.003, 0.007), increased maternal weight was positively associated with AXL (0.004 mm; 95% CI: 0.0001, 0.008). Birth length was associated with an increase in teenage AXL (0.067 mm; 95% CI: 0.032, 0.10) and flatter RCC (0.023 mm; 95% CI: 0.013, 0.034) and increasing birth weight was associated with flatter RCC (0.005 mm; 95% CI: 0.0003, 0.009). An increase in teenage height was associated with a lower MSE (− 0.007 D; 95% CI: − 0.013, − 0.001), an increase in AXL (0.021 mm; 95% CI: 0.015, 0.028) and flatter RCC (0.008 mm; 95% CI: 0.006, 0.010). Weight at 15 years was associated with an increase in AXL (0.005 mm; 95% CI: 0.001, 0.009).

Conclusions

At each life stage (pre-natal, birth, and teenage) height and weight, but not BMI, demonstrate an association with AXL and RCC measured at age 15 years. However, the negative association between refractive error and an increase in height was only present at the teenage life stage. Further research into the growth pattern of ocular structures and the development of refractive error over the life-course is required, particularly at the time of puberty.

Association of maternal diabetes with attention deficit/hyperactivity disorder (ADHD) in offspring: A meta-analysis and review

AIMS

Researches on the relationship between maternal pregestational or gestational diabetes and attention deficit/hyperactivity disorder (ADHD) in offspring provided inconsistent findings; therefore, we performed an updated and comprehensive literature review and meta-analysis to evaluate the available evidence.

METHOLDS

Relevant articles in Pubmed, Web of Science, Cochrane, Embase, and Wanfang database published until January 2019 were searched without language restriction. We performed a meta-analysis about maternal pregestational and gestational diabetes and risk of ADHD in offspring using odds ratio (OR), relative risk (RR), hazard ratio (HR) and 95% confidence interval (95% CI) extracted from each study.

RESULTS

Seven articles were included in this study and a total of 3,169,529 participants were accumulated. We found maternal pregestational diabetes increased the risk of ADHD in offspring by 44% (95% CI was 1.32-1.57).

CONCLUSIONS

Maternal pregestational diabetes is a potential adverse risk of ADHD in offspring. Considering the limited amount of reliable information availabe. In the future, more in-depth and detailed researches, especially population-based prospective cohort studies, are needed to explore this topic more comprehensively.

Maternal and Neonatal Outcomes among Obese Pregnant Women in King Abdulaziz University Hospital: A Retrospective Single-Center Medical Record Review

Intoruction:

Pregnancy results in different physiological changes to the pregnant body resulting in weight gain. This added weight can result in poor pregnancy outcomes in obese women.

Aim:

To assess the adverse maternal and neonatal outcomes among obese pregnant women.

Methods:

This is a retrospective record review conducted on obese pregnant women who delivered in the last five years attending King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Therefore, for analysis we used the following; 1- descriptive analysis, 2- Chi-square test, Pearson correlation, independent t-test, and one-way ANOVA to test the difference in obese and adverse pregnancy outcomes. Advance statistics such as binary, and multinomial logistic regression were used to examine the relationship between obesity and all adverse pregnancy outcomes.

Results:

A total of 1037 obese pregnant women were enrolled in our study including 620 (59.8%) obese in class I (30-34.9), 262 (25.3%) obese in class II (35-39.9), and 155 (14.9%) obese in class III (40). About 74.73% of the population were Saudis. The average age was 31.96 (5.79) years. Out of 1037 obese pregnant women, 449 did develop undesired antepartum outcomes, while 729 and 163 had adverse neonatal, and postpartum outcomes. Antepartum variables such as preeclampsia, gestational diabetes mellitus, impaired glucose tolerance test, antiphospholipid syndrome, premature rupture of membranes, placenta previa, anemia, urinary tract infection, and oligohydramnios, and rate of Cesarean section were significantly associated with obesity (P<0.05). Postpartum variables such as vaginal laceration, perianal laceration, postpartum hemorrhage, and endometritis were also significantly associated with obesity (P<0.05). Moreover, adverse neonatal outcomes such as low APGAR scores at 1 and 5 minutes, birthweight, gestational age, admission to neonatal intensive care unit, intrauterine fetal death, and neonatal death, were significant significantly associated with obesity (P<0.05).

Conclusion:

As our study demonstrated, maternal obesity resulted in adverse outcomes for the mother and fetus. Hence, to yield a better outcome for these women and their offspring, periconceptional counseling, conducting health education, and comprehensive plan prior to their pregnancy should be enforced.

The influence of maternal vitamin D supplementation on infant vitamin D status: A systematic review and meta-analyses

BACKGROUND

Inconsistencies exist with regard to effect of maternal vitamin D supplementation on infant vitamin D status. The inconsistencies could be attributed to numerous factors, such as duration of intervention and dosage, among others. In this work, we conducted a systematic review and meta-analysis to determine the influence of maternal vitamin D supplementation on infant vitamin D status.

METHODS

A comprehensive systematic search was performed in Scopus, EMBASE, Web of Science, and PubMed/MEDLINE, by investigators, from database inception until November 2019, without using any restrictions. Weighted mean difference (WMD) with the 95 % CI was used for assessing the effects of maternal vitamin D supplementation on 25(OH) D levels in infants.

RESULTS

Overall results from 14 studies revealed a non-significant effect of maternal vitamin D administration on the level of 25(OH) D in breastfeeding infants (WMD: -0.464 ng/mL, 95 % CI: -6.68 to 5.75, p = 0.884, I² = 98 %). Subgroup analyses demonstrated that vitamin D supplementation dosage ≥2000 IU/day (WMD: 9 ng/mL, 95 % CI: 8.19, 9.82, I² = 99 %) and intervention duration ≥20 weeks (WMD: 16.20 ng/mL, 95 % CI: 14.89, 17.50, I² = 99 %) significantly increased 25(OH) D.

CONCLUSIONS

The main results indicate a non-significant increase in infant vitamin D following maternal vitamin D supplementation. Additionally, vitamin D supplementation dosage ≥2000 IU/day and intervention duration ≥20 weeks significantly increased infant 25(OH) D.

Maternal and Perinatal outcome after Ramadan Fasting

Objective:

To determine maternal and perinatal outcome after Ramadan fasting during pregnancy

Methods:

This cross sectional study was conducted at The Department of Obstetrics and Gynaecology, Nishtar Hospital, Multan from May to October 2019. A total of 226 women attending labour room, aged 18–35 years, having gestational amenorrhoea 15 – 40 weeks of gestation were included. Women who fasted for more than 15 days were compared with those who did not fast or fasted for less than 15 days in the month of Ramadan. Demographical profile along with maternal and perinatal outcomes were compared between the study groups considering p value less than 0.05 as significant.

Results:

Out of 226 women, 58 (25.7%) fulfilled the criteria to be included in the fasting group while remaining 168 (74.3%) were slotted in the non-fasting group. There was no difference (p value > 0.05) in between the both group with respect to demographical characteristics except significantly less women were employed in the fasting group (p value=0.0246). No statistical difference was found in terms of maternal or perinatal outcomes between both the study groups.

Conclusion:

Fasting women were not found to have poor maternal and fetal outcomes when compared to non-fasting women.

Coverage of intermittent preventive treatment of malaria in pregnancy (IPTp) influences delivery outcomes among women with obstetric referrals at the district level in Ghana

Background

The aim of the study was to determine the coverage of intermittent preventive treatment of malaria in pregnancy (IPTp) and its relationship with delivery outcomes among obstetric referral cases at the district level of healthcare.

Methods

An implementation research within three districts of the Greater Accra region was conducted from May 2017 to February 2018, to assess the role of an enhanced inter-facility communication system on processes and outcomes of obstetric referrals. A cross-sectional analysis of the data on IPTp coverage as well as delivery outcomes for the period of study was conducted, for all the referrals ending up in deliveries. Primary outcomes were maternal and neonatal complications at delivery. IPTp coverage was determined as percentages and classified as adequate or inadequate. Associated factors were determined using Chi square. Odds ratios (OR, 95% CI) were estimated for predictors of adequate IPTp dose coverage for associations with delivery outcomes, with statistical significance set at p = 0.05.

Results

From a total of 460 obstetric referrals from 16 lower level facilities who delivered at the three district hospitals, only 223 (48.5%) received adequate (at least 3) doses of IPTp. The district, type of facility where ANC is attended, insurance status, marital status and number of antenatal clinic visits significantly affected IPTp doses received. Adjusted ORs show that adequate IPTp coverage was significantly associated with new-born complication [0.80 (0.65–0.98); p = 0.03], low birth weight [0.51 (0.38–0.68); p < 0.01], preterm delivery [0.71 (0.55–0.90); p = 0.01] and malaria as indication for referral [0.70 (0.56–0.87); p < 0.01]. Positive association with maternal complication at delivery was seen but was not significant.

Conclusion

IPTp coverage remains low in the study setting and is affected by type of health facility that ANC is received at, access to health insurance and number of times a woman attends ANC during pregnancy. This study also confirmed earlier findings that, as an intervention IPTp prevents bad outcomes of pregnancy, even among women with obstetric referrals. It is important to facilitate IPTp service delivery to pregnant women across the country, improve coverage of required doses and maximize the benefits to both mothers and newborns.

Delivering prenatal pertussis vaccine through maternity services in England: What is the impact on vaccine coverage?

BACKGROUND

Prenatal pertussis vaccination was introduced in 2012 in England and is primarily delivered through general practice. Since 2017 some maternity services are commissioned to offer it too. We aimed to describe the maternity service delivery of prenatal pertussis vaccination and its impact on vaccine uptake.

METHODS

We described the proportion of maternity services in England commissioned to offer pertussis vaccination to pregnant women in 2017/18 and the proportion of women vaccinated in this setting using a self-administered survey of NHS commissioners. We categorised clinical commissioning groups (CCGs) in England into "implementing" and "non-implementing" pertussis vaccination in maternity services. We identified CCGs where vaccination data was reliably transferred from maternity services to primary care records (source of routine data on vaccine uptake) and among those compared changes in vaccine uptake in implementing vs non-implementing CCGs between March 2016 (before implementation) and March 2018 (after).

FINDINGS

Of 141 maternity service units in England, 61% delivered prenatal pertussis vaccine in 2017/18. Of those 57.0% of maternity services immunized less than 10% of pregnant women and only 7.1% of maternity services immunized more than 40% of pregnant women. Between March 2016 and March 2018, coverage increased by 19.6% among non-implementing CCGs compared with 17.8% among all implementing CCGs (difference -2.2, p = 0.48) and 28.2% among implementing CCGs with reliable methods of data transfer (difference 8.6, p = 0.04). This difference translated to a difference of 1.6 percentage points in absolute terms.

INTERPRETATION

Delivering pertussis vaccine through maternity services has a moderate but important impact on vaccine uptake. There is a need to improve data transfer on vaccines administered in maternity service units to primary care. Maternity services should offer the vaccine to improve coverage and thus optimise protection for young infants. Barriers to effective programme implementation should be investigated and addressed.

Maternal and neonatal outcomes following a prolonged second stage of labor: A meta-analysis of observational studies

Several articles investigated the impact of prolonged second stage of labor on maternal and neonatal outcomes; however, strict consensus is still lacking. The purpose of the present meta-analysis is to investigate risk factors that contribute to the pathophysiology of prolonged labor as well as effect sizes of maternal and neonatal morbidity. We searched Medline, Scopus, Clinicaltrials.gov, EMBASE, Cochrane Central Register of Controlled Trials CENTRAL and Google Scholar database. Observational studies (prospective and retrospective) were considered eligible for inclusion in the present meta-analysis. To minimize the possibility of article losses we avoided language, country and date restrictions. Meta-analysis was performed with the RevMan 5.3 and secondary analysis with Rstudio. Overall, 13 studies were included in the present systematic review that comprised 337.845 parturient. Prolonged second stage was associated with higher odds of postpartum hemorrhage, chorioamnionitis, endometritis, postpartum fever and obstetric anal sphincter injury. Persistent occiput posterior position and shoulder dystocia were also more prevalent compared to women with normal duration of the second stage. The need for admission to the neonatal intensive care unit was higher as well as the risk of developing neonatal sepsis. On the other hand, the odds of perinatal death were comparable among cases with prolonged and normal duration of the second stage. The results of the present meta-analysis clearly indicate that deliveries following a prolonged second stage of labor are at increased risk of maternal and neonatal complications. The presented effect estimates can be used in current clinical practice during patient counseling.
