Sustaining the momentum for adult vaccination post-COVID-19 to leverage the global uptake of life-course immunisation: A scoping review and call to action

OBJECTIVES

The COVID-19 pandemic changed the adult vaccination landscape, possibly permanently. This review attempts to quantitate the magnitude of those changes.

METHODS

PubMed was searched for studies on adult / life-course vaccination between 1 January 2020 until 8 November 2022.

RESULTS

Twenty-one articles were identified and observations summarised as positive developments/impediments to life-course immunisation, and areas needing policy and structural reform. Unprecedented funding, international co-operation and technical advances led to COVID-19 vaccines authorised in record time. Investments in infrastructure and an expanded healthcare workforce streamlined vaccine delivery to adults. Constant media coverage and targeted messaging have improved health literacy. Conversely, the speed of vaccine development was perceived as a safety risk, and an 'infodemic' of misinformation propagated through social media negatively influenced vaccine uptake. Vaccine access and affordability remains inequitable among older adults and minority groups.

CONCLUSIONS

The COVID pandemic led to an opportunity to permanently change policies, attitudes, and systems for vaccine delivery to adults to establish a global life-course approach to immunisation. This is a call for action to sustain the momentum triggered by the COVID-19 pandemic. Addressing inequalities, improving health literacy and optimally using social media are critical to sustain adult vaccinations in post-COVID-19 era.

Influence of an Early Human Milk Diet on the Duration of Parenteral Nutrition and Incidence of Late-Onset Sepsis in Very Low Birthweight (VLBW) Infants: A Systematic Review

Introduction: Human milk is the preferred source of enteral nutrition for very low birthweight (VLBW) infants, and it possibly decreases dependence on parenteral nutrition (PN) and reduces incidence of late-onset sepsis (LOS). No systematic review to date has specifically addressed the value of early versus late introduction of human milk diet (HMD) on duration of PN and incidence of LOS among VLBW infants. Objective: To review the evidence for an early versus late introduction of HMD on duration of PN and incidence of LOS in VLBW infants. Method: Preferred reporting items for systematic reviews and meta-analysis-guided search of EMBASE and PubMed/Medline databases was conducted for this systematic review using phrases addressing population, intervention, comparator, and outcome framework to identify articles published over the past two decades without language restrictions. Full-text articles (both observational and randomized) that studied an early versus late initiation of HMD were included. Mean difference (MD) and relative risk (RR) with 95% confidence intervals (CIs) were calculated for PN and LOS. Quality of evidence was analyzed using UK National Service Framework and the risk-of-bias was assessed using Robvis®. Results: One randomized controlled trial (RCT) and two observational studies (two English and one Chinese) recruited 474 VLBW infants (455 analyzed). Among an intrauterine growth-restricted cohort enrolled in the RCT (n = 72), early HMD resulted in statistically significant reduction in PN dependence. However, no statistically significant difference was found in LOS. Two observational studies found similar reductions in PN duration and LOS incidence among the early HMD cohort. One observational study reported significant PN reduction; however, the incidence of LOS did not reach statistical significance in either case. Conclusion: An early HMD may reduce the duration of PN for a growth-restricted VLBW cohort. Observational studies suggesting reduced PN and LOS from early HMD endorse the need for bioactivity-focused human milk research. Variations in feeding guidelines among VLBW infants have the potential to influence neonatal outcomes significantly.

Maternal awareness, acceptability and willingness towards respiratory syncytial virus (RSV) vaccination during pregnancy in Ireland

BACKGROUND

Respiratory syncytial virus (RSV) is the world's leading cause of viral acute lower respiratory infections (ALRI) in infants. WHO has identified maternal RSV vaccination a priority and candidate vaccines are in development; however, vaccine hesitancy remains an impediment to successful implementation of maternal immunization. This study, the largest antenatal survey conducted to-date, aimed to examine maternal RSV awareness, likely acceptance of RSV vaccination in pregnancy, and attitudes to maternal vaccination.

METHODS

Pregnant women of all gestations attending antenatal clinic of a university maternity hospital in Ireland were invited to participate. An information leaflet provided, consent obtained, and survey administered examining RSV awareness, willingness to avail of antenatal RSV vaccination, factors influencing acceptability and preferred sources of assistance. Research Ethics Committee (REC) approval obtained, and general data protection regulation (GDPR) guidelines followed.

RESULTS

528 women completed the survey. A large proportion (75.6%) had never heard of RSV, yet 48.5% would still avail of a vaccine, 45.8% were undecided and only 5.3% would not. The main factor making vaccination acceptable to women (76.4%) was that it protects their infant from illness (p < .001, CV 0.336 for association with acceptance) and general practitioner (GP) was the preferred guidance source in decision-making (57.7%).

CONCLUSIONS

Despite low levels of maternal awareness of RSV, pregnant women in Ireland are open to availing of antenatal vaccination. Maternal immunization strategies need to focus on infant's protection from RSV-associated ALRI along with vaccine safety, and build on an interdisciplinary collaboration of maternal, neonatal, primary care and public health services.

The microbial pathology of maternal perinatal sepsis: A single-institution retrospective five-year review

INTRODUCTION

Greater than half of in-hospital maternal deaths are caused by sepsis, a condition that occurs when infection exceeds local tissue containment and results in organ dysfunction. Determining the source of infection can be challenging. Microbiological cultures of the uterine cavity are often difficult to obtain, so antimicrobial susceptibility results may not be available to guide treatment. The aim of this retrospective study was to assess the potential clinical value of microbiology samples used in the maternal "septic screen" of patients in an Irish maternity hospital.

METHODS

A review was completed of all maternal "septic screen" (i.e., high vaginal swabs, placenta swabs, blood cultures, throat swabs and urine samples) microbiology results from July 2016 to December 2021.

RESULTS

In the relevant period, 845 patients were subject to a "septic screen", of whom 430 also had a placental swab collected. These 430 patients comprise our study population. 2% of blood cultures yielded potential pathogens, compared with 37%, 33%, 9% and 7% respectively for placental swabs, high vaginal swabs, throat swabs and urine specimens. 95% of blood cultures were sterile, compared with 52%, 0%, 0% and 53% respectively for placental swabs, high vaginal swabs, throat swabs and urine specimens.

CONCLUSION

Of the five microbiological specimen types examined, placental swabs yielded the highest number of potential pathogens. Our results suggest that placental swabs are useful specimens for detecting potential pathogens from the uterine cavity, the most common source of perinatal infections.

Association between the development of bronchopulmonary dysplasia and platelet transfusion: a protocol for a systematic review and meta-analysis

Background

There is a lack of consensus on the management of thrombocytopenia in preterm infants, and the threshold for prophylactic platelet transfusion varies widely among clinicians and institutions. Reports in animal models suggested that platelets may play a relevant role in lung alveolarization and regeneration. Bronchopulmonary dysplasia (BPD) is a severe respiratory condition with a multifactorial origin that affects infants born at the early stages of lung development. Recent randomized controlled trials on the platelets count threshold for prophylactic transfusions in preterm infants with thrombocytopenia suggest that a higher exposition to platelet transfusion may increase the risk of BPD. Here, we report a protocol for a systematic review, which aims to assist evidence-based clinical practice and clarify if the administration of platelet products may be associated with the incidence of BPD and/or death in preterm infants.

Methods

MEDLINE, Embase, Cochrane databases, and sources of gray literature for conference abstracts and trial registrations will be searched with no time or language restrictions. Case-control studies, cohort studies, and nonrandomized or randomized trials that evaluated the risk for BPD and/or death in preterm infants exposed to platelet transfusion will be included. Data from studies that are sufficiently similar will be pooled as appropriate. Data extraction forms will be developed a priori. Observational studies and nonrandomized and randomized clinical trials will be analyzed separately. Odds ratio with 95% confidence interval (CI) for dichotomous outcomes and the mean difference (95% CI) for continuous outcomes will be combined. The expected heterogeneity will be accounted for using a random-effects model. Subgroup analysis will be performed based on a priori-determined covariate of interest. In case of sufficient homogeneity of interventions and outcomes evaluated, results from subgroups of studies will be pooled together in a meta-analysis.

Discussion

This systematic review will investigate the association of BPD/death with platelet components administration in preterm infants, and, consequently, it will provide reliable indications for the evidence-based management of premature patients with thrombocytopenia.

Changes in preterm birth and stillbirth during COVID-19 lockdowns in 26 countries

Preterm birth (PTB) is the leading cause of infant mortality worldwide. Changes in PTB rates, ranging from -90% to +30%, were reported in many countries following early COVID-19 pandemic response measures ('lockdowns'). It is unclear whether this variation reflects real differences in lockdown impacts, or perhaps differences in stillbirth rates and/or study designs. Here we present interrupted time series and meta-analyses using harmonized data from 52 million births in 26 countries, 18 of which had representative population-based data, with overall PTB rates ranging from 6% to 12% and stillbirth ranging from 2.5 to 10.5 per 1,000 births. We show small reductions in PTB in the first (odds ratio 0.96, 95% confidence interval 0.95-0.98, P value <0.0001), second (0.96, 0.92-0.99, 0.03) and third (0.97, 0.94-1.00, 0.09) months of lockdown, but not in the fourth month of lockdown (0.99, 0.96-1.01, 0.34), although there were some between-country differences after the first month. For high-income countries in this study, we did not observe an association between lockdown and stillbirths in the second (1.00, 0.88-1.14, 0.98), third (0.99, 0.88-1.12, 0.89) and fourth (1.01, 0.87-1.18, 0.86) months of lockdown, although we have imprecise estimates due to stillbirths being a relatively rare event. We did, however, find evidence of increased risk of stillbirth in the first month of lockdown in high-income countries (1.14, 1.02-1.29, 0.02) and, in Brazil, we found evidence for an association between lockdown and stillbirth in the second (1.09, 1.03-1.15, 0.002), third (1.10, 1.03-1.17, 0.003) and fourth (1.12, 1.05-1.19, <0.001) months of lockdown. With an estimated 14.8 million PTB annually worldwide, the modest reductions observed during early pandemic lockdowns translate into large numbers of PTB averted globally and warrant further research into causal pathways.

Exclusive Human Milk Diet for Extremely Premature Infants: A Novel Fortification Strategy That Enhances the Bioactive Properties of Fresh, Frozen, and Pasteurized Milk Specimens

Background: Human milk (HM) fortification has been recommended for the nutritional optimization of very low-birthweight infants. This study analyzed the bioactive components of HM and evaluated fortification choices that could accentuate or attenuate the concentration of such components, with special reference to human milk-derived fortifier (HMDF) offered to extremely premature infants as an exclusive human milk diet. Materials and Methods: An observational feasibility study analyzed the biochemical and immunochemical characteristics of mothers' own milk (MOM), both fresh and frozen, and pasteurized banked donor human milk (DHM), each supplemented with either HMDF or cow's milk-derived fortifier (CMDF). Gestation-specific specimens were analyzed for macronutrients, pH, total solids, antioxidant activity (AA), α-lactalbumin, lactoferrin, lysozyme, and α- and β-caseins. Data were analyzed for variance applying general linear model and Tukey's test for pairwise comparison. Results: DHM exhibited significantly lower (p < 0.05) lactoferrin and α-lactalbumin concentrations than fresh and frozen MOM. HMDF reinstated lactoferrin and α-lactalbumin and exhibited higher protein, fat, and total solids (p < 0.05) in comparison to unfortified and CMDF-supplemented specimens. HMDF had the highest (p < 0.05) AA, suggesting the potential capability of HMDF to enhance oxidative scavenging. Conclusion: DHM, compared with MOM, has reduced bioactive properties, and CMDF conferred the least additional bioactive components. Reinstatement and further enhancement of bioactivity, which has been attenuated through pasteurization of DHM, is demonstrated through HMDF supplementation. Freshly expressed MOM fortified with HMDF and given early, enterally, and exclusively (3E) appears an optimal nutritional choice for extremely premature infants.

Impact of breastfeeding on the incidence and severity of respiratory syncytial virus (RSV)-associated acute lower respiratory infections in infants: a systematic review highlighting the global relevance of primary prevention

BACKGROUND

Respiratory syncytial virus (RSV) is the principal cause of acute lower respiratory infections (ALRI) among infants worldwide, and an important cause of morbidity, hospitalisation and mortality. While infants are universally exposed to RSV, most mortality occurs among normal term infants from low-income and middle-income countries. Breastfeeding has been suggested to have a protective effect against RSV infection. This study aims to determine the association of breastfeeding on the frequency and severity of RSV-associated ALRI among infants.

METHODS

A systematic review was conducted using keywords and Medical Subject Headings on MEDLINE, PubMed, Google Scholar, EMBASE, MedRxiv and Cochrane Central Register of Controlled Trials. Full-text articles published in English from 2000 to 2021 that studied exclusively or partially breastfed infants who developed RSV-associated ALRI <12 months of age were included. Covidence software-based evidence extraction and Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol guidelines were followed. Quality of evidence was analysed using UK National Service Framework grading and the risk-of-bias assessment using Robvis.

RESULTS

Among 1368 studies screened, 217 qualified full-text review and 198 were excluded based on pre-agreed criteria. Nineteen articles published from 12 countries that included 16 787 infants from 31 countries (of which 8 middle-income) were retained for analysis. Results indicate that non-breastfeeding practices pose a significant risk for severe RSV-associated ALRI and hospitalisation. Exclusive breastfeeding for >4-6 months significantly lowered hospitalisation, length of stay, supplemental oxygen demand and admission to intensive care units.

CONCLUSION

In the context of no effective or standardised treatment for established RSV-associated ALRI, available evidence suggest that breastfeeding is associated with lower frequency and severity of RSV-associated ALRI, based on observational studies of variable grades of evidence and risk-of-bias. With both exclusive and partial breastfeeding benefiting infants who develop RSV-associated ALRI, breastfeeding should be promoted globally as an adjunct primary prevention; in addition to emerging immunoprophylaxis and maternal immunisation strategies.

A repeated cross-sectional analysis of breastfeeding initiation rates in Ireland for two decades and 10 recommended priorities for improvement

Despite a number of public health and policy-based initiatives, Ireland's national breastfeeding rates are among the lowest globally. Regionally, the Mid-West of Ireland has historically had low breastfeeding initiation rates, and parts of its major urban area such as Limerick City suffer the highest levels of economic deprivation in the country. In that context, this repeated cross-sectional study analysed breastfeeding initiation trends in the Mid-West of Ireland for two decades, from 2001 to 2020 inclusively. Statistical analysis revealed persistently low percentages of women initiating breastfeeding in the region. Time series analyses of the data demonstrated that overall breastfeeding rates are increasing, but continue to be lower than Irish national averages. From these findings and a narrative review of published research, we determined 10 plausible reasons for these consistently low breastfeeding rates. Arising from these, we propose '10 Priorities' to increase the breastfeeding initiation rates in Ireland.

Steroid use for established bronchopulmonary dysplasia: study protocol for a systematic review and meta-analysis

INTRODUCTION

Postnatal steroids during the first few weeks of life have been demonstrated to be effective in decreasing the incidence of bronchopulmonary dysplasia (BPD), a serious chronic respiratory condition affecting preterm infants. However, this preventive option is limited by the concern of neurological side effects. Steroids are used to treat established BPD in an attempt to reduce mortality, and length of stay and home oxygen therapy, both of which associated with high levels of parental stress and healthcare costs. Moreover, a late timing for steroid treatment may show a more favourable safety profile in terms of neurodevelopment outcomes, considering the added postnatal brain maturation of these infants. Here, we report a protocol for a systematic review, which aims to determine the efficacy and long-term safety of postnatal steroids for the treatment of established BPD in preterm infants.

METHODS AND ANALYSIS

MEDLINE, Embase, Cochrane databases and sources of grey literature for conference abstracts and trial registrations will be searched with no time or language restriction. We will include case-control studies, cohort studies and non-randomised or randomised trials that evaluate postnatal steroids for infants diagnosed with moderate or severe established BPD at 36 weeks' postmenstrual age. We will pool data from studies that are sufficiently similar to make this appropriate. Data extraction forms will be developed a priori. Observational studies and non-randomised and randomised clinical trials will be analysed separately. We will combine OR with 95% CI for dichotomous outcomes and the mean difference (95% CI) for continuous outcomes. We will account for the expected heterogeneity by using a random-effects model. We will perform subgroup analysis based on the a priori determined covariate of interest.

ETHICS AND DISSEMINATION

Systematic reviews are exempted from approval by an ethics committee. Attempts will be sought to publish all results.

Activity Levels and Outcomes of a Standalone Regional Paediatric High Dependency Unit

Aim The Paediatric High Dependency Unit (PHDU) at University Hospital Limerick (UHL) operates as the only standalone unit outside of Dublin centres. The aim of this study was to describe a regional PHDU population, compare outcomes with international standards (PICANet) and ensure adequate clinical governance. Methods This is a retrospective analysis of 126 admission records from January - December 2019. Results There were 126 admissions to PHDU in 2019, of which respiratory (n=81, 64.3%) and neurological (n=23, 18.3%) subgroups represented the largest populations. Median length of stay was two days with mean age of admission 3.97 ± 4.5 years and slightly more male admissions (56%). Of the total, 65% required oxygen, 32.1% needed CPAP directly and 38% commenced high-flow, of whom 29% transitioned to CPAP. Transfer for tertiary care was required in 10.3%, of whom 7.9% needed PICU. Conclusion The data show UHL PHDU to have a patient population reflecting international trends as well as producing satisfactory patient outcomes. With a low rate of transfer for tertiary care and given that 15 other paediatric units exist in the Republic of Ireland outside Dublin, development of regional PHDU capacity would provide great opportunity to decrease strain on PICU bed capacity, particularly during busy Winter months.

Mobile-Assisted Virtual Bonding Enables Breast Milk Supply in Critically Ill Mothers With COVID-19: A Reflection on the Feasibility of Telelactation

The separation of the mother-infant pair during the immediate postpartum period has been shown to impair the initiation and sustenance of breastfeeding. For critically ill mothers with coronavirus disease 2019 (COVID-19), the imposed isolation generates anxiety for their health and that of the offspring. In this study, we present a few cases where a favorable outcome was observed through a telehealth initiative for mothers with severe COVID-19 pneumonia, which involved sharing pictures and videos of newborn infants with the mothers during the ongoing severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) pandemic in a maternity hospital in northern Iran. In addition to the subjective maternal wellbeing offered by the visual and auditory cues from the infant, this technology-assisted telelactation'/'mobile-lactation'/'e-lactation' could potentially enhance the mother's capacity to initiate emotional bonding with the infant and be an adjunct in achieving and maintaining her lactation goals while offering the best nutritional choice for the infant.

Unprecedented reduction in births of very low birthweight (VLBW) and extremely low birthweight (ELBW) infants during the COVID-19 lockdown in Ireland: a 'natural experiment' allowing analysis of data from the prior two decades

BACKGROUND

Aetiology of births involving very low birthweight (VLBW) and extremely low birthweight (ELBW) infants is heterogeneous and preventive strategies remain elusive. Socioenvironmental measures implemented as Ireland's response to the SARS-CoV-2 virus (COVID-19) pandemic represented a national lockdown, and have possibly influenced the health and well-being of pregnant women and unborn infants.

METHODS

Regional trends of VLBW and ELBW infants in one designated health area of Ireland over two decades were analysed. Poisson regression and rate ratio analyses with 95% CI were conducted. Regional data covering most of the lockdown period of 2020 were compared with historical regional and national data and forecasted national figures for 2020.

RESULTS

Poisson regression analysis found that the regional historical VLBW rate per 1000 live births for January to April, 2001-2019 was 8.18 (95% CI 7.21 to 9.29). During January to April 2020, an unusually low VLBW rate of just 2.17 per 1000 live births was observed, reflecting a rate ratio of 3.77 (95% CI 1.21 to 11.75), p=0.022, representing a 73% reduction of VLBW during the first 4 months of 2020 compared with same period for the preceding two decades. There were no ELBW infants admitted to the regional neonatal intensive care unit. National Irish VLBW rate for 2020 is forecasted to be reduced to approximate 400 per 60 000 births compared with the historical 500-600 range.

CONCLUSION

An unprecedented reduction in regional births of VLBW and ELBW infants was observed in Ireland coinciding with the COVID-19 lockdown. Potential determinants of this unique temporal trend possibly reside in the summative socioenvironmental impact of the COVID-19 lockdown. Our findings, if mirrored in other regions that have adopted a lockdown, demonstrate the potential to evaluate these implicated behavioural and socioenvironmental modifiers to positively influence VLBW and ELBW rates globally.

Word cloud analysis and single word summarisation as a new paediatric educational tool: Results of a neonatal application

AIMS

To analyse the value of computerised 'word cloud' (WC) generated from spontaneously articulated 'single word summarisation' (SWS) by medical students to assist their learning during the neonatal intensive care unit placement. To highlight WC as a potential new tool in paediatric teaching, improving student engagement and reflective feedback.

METHODS

An observational study was conducted in the neonatal intensive care unit of University Maternity Hospital Limerick, Ireland for 5 years (October 2012 to September 2017). One faculty member prospectively recorded SWS in neonatology by graduate entry medical students. An online 'WC generator' under an open-source licence was used to compute the WC. Hospital audit committee approved the study.

RESULTS

A total of 268 SWS were recorded consecutively from 268 medical students towards the WC generation. Structured multi-response student feedback showed SWS and WC as stimulating, unique and creative. Powerpoint presentation of the computed WC prompted students to reflect on their chosen words and that of peers.

CONCLUSIONS

Visualisation of medical student-generated SWS as a WC could stimulate interaction, reflection and clinical discussion, thus assisting teachers to foster better student engagement. This innovative educational tool equips students to 'convey more with fewer words' and has the potential transferability to other clinical disciplines.

Health Care Professionals' Perspectives on Life-Course Immunization: A Qualitative Survey from a European Conference

Today, fewer children die each year from vaccine-preventable diseases than older adults. Health systems need new immunization strategies to tackle the burden of vaccine-preventable disease in an aging society. A life-course immunization (LCI) approach-which entails vaccination throughout an individual's lifespan-enables adults to age with reduced risk to disease, thereby enabling healthy, active and productive aging. We conducted an audience response system (ARS)-based survey to investigate HCP perspectives on LCI in an opportunistic sample of 222 health care professionals (HCPs) from around the world who attended a European infectious diseases conference. Survey results show that LCI is a priority for HCPs (77.4%-88.6%), with most of them stating the need to frame it as a part of a healthy lifestyle (91.0%-100.0%). Insufficient LCI recommendations by vaccine providers (12.9%-33.3%) and governments (15.2%-41.9%) and insufficient targeted budget allocation (6.1%-21.7%) were indicated as the main barriers to implement LCI, ahead of vaccine hesitancy (9.7%-15.2%). HCPs were willing to make LCI a gateway to healthy aging but need support to work together with other stakeholders involved in the vaccination journey. This could be a step towards equitable health care for all of society.

Time to positivity (TTP) of neonatal blood cultures: a trend analysis over a decade from Ireland

Background and aims: Blood culture (BC) remains gold standard for the evaluation and diagnosis of neonatal sepsis. Time when BC becomes positive and the type of microorganism isolated are crucial in deciding the antimicrobial management. Likely pathogenicity of organisms growing in BC could potentially be predicted based on the "time to positivity" (TTP). We aimed to estimate the predictive value of isolating a likely pathogenic organism depending on TTP; evaluate the aetiological trend and neonatal mortality rate due to culture-proven neonatal sepsis for over a decade and verify whether the application of a "36 hour rule" to discontinue empiric antibiotics in well newborn infants with negative BC would be safe.Methods: Retrospective review of BC results over a 14-year period from a regional neonatal unit in Ireland. Laboratory data were independently extracted in relation to BC results from the laboratory information management system (LIMS-iLAB). Neonatal mortality data were collected from multiple sources. Statistical analysis included logistic regression, chi-square, and Mann-Whitney U-test.Results: Over a 14-year period 11,432 neonatal BC specimens were incubated of which 605 (5.3%) turned positive. Overall, the commonest organism grown was coagulase-negative Staphylococcus (CoNS), 416 (68.8%). Main pathogenic organisms were Staphylococcus aureus 23 (3.8%), Enterococcus spp. 22 (3.6%), E.coli 21 (3.5%), group B Streptococcus (GBS) 18 (3.0%), and Klebsiella species 9 (1.5%). Gram-negative organisms had the shortest TTP, with Klebsiella spp. having a median TTP of 10 h and E. coli 11 h. For Gram-positives, GBS had a median TTP of 12 h, Enterococcus species 14 h, with S. aureus growing at a median time of 15 h. All of the Klebsiella spp. and other Coliforms were detected within 24 h, with, 95.2% of E.coli, 94.4% of GBS, 95.5% of Enterococci, and 95.7% of S. aureus, flagging positive in 24 h. Using logistic regression the omnibus test of the coefficients in the resulting model was significant (p < .001). Our observed coefficient (β) for TTP was 0.144; shorter the TTP higher was the likelihood of isolating a pathogenic organism, with an odds ratio (OR) of 1.155. We also report a relatively low blood culture proven sepsis-specific neonatal mortality rate of 0.403/1000 live births and in all such instances observed TTP was less than 24 h.Conclusion: Duration of this study exceeds that of most of the neonatal blood culture TTP analysis published to-date. A shorter TTP is an important adjunct to suggest the growth of a pathogenic organism while managing suspected neonatal sepsis. TTP if < 24 h per se would not necessarily confirm the growth of a highly pathogenic organism; however, if a positive growth is likely to happen for a significant neonatal pathogen, in more than 98% the TTP would be within 24 h. This offers the clinician more of negative predictive value than a positive one; when there is no growth in BC. Our observation on TTP reiterate the National Institute of Health and Care Excellence (NICE) guideline of discontinuation of empiric antibiotics after 36 h in and clinically well and BC negative newborn infants.

Evidence-based design for neonatal units: a systematic review

Evidence-based design (EBD) of hospitals could significantly improve patient safety and make patient, staff and family environments healthier. This systematic review aims to determine which neonatal intensive care unit design features lead to improved neonatal, parental and staff outcomes. Medline, CINAHL, Web of Science Citation Index and Cochrane Central Register of Controlled Trials Registry, were searched in January 2017. Using combinations of the relevant key words, review was performed following the recommended guidelines for reporting systematic reviews. English language limitation was applied and term limited to 2006–2016. Included studies were assigned a grade based upon their level of evidence and critically appraised using defined tools. Data were not synthesized for meta-analysis due to nature of literature reviewed and heterogeneity. Three thousand five hundred ninety-two titles were screened with 43 full-texts assessed for eligibility. Twenty nine studies were deemed eligible for inclusion. These included 19 cohort studies, two qualitative studies, seven cross-sectional studies, and one randomised control trial. Grey literature search from guidelines, and repositories yielded an additional 10 guidelines. ‘Single family room’ (SFR) design for neonatal units is recommended. An optimally designed neonatal unit has many possible health implications, including improved breastfeeding, infection and noise control, reduced length of stay, hospitalisation rates and potentially improved neonatal morbidity and mortality. High quality, family centred care (FCC) in neonatology could be assisted through well grounded, future proofed and technology enabled design concepts that have the potential to impact upon early life development.

Life-course immunization as a gateway to health

INTRODUCTION

Extending the benefits of vaccination against infectious diseases from childhood throughout the entire life-span is becoming an increasingly urgent priority in view of the world's aging population, emergence and reemergence of infectious diseases, and the necessity to invest more on prevention versus cure in global healthcare. Areas covered: This perspective discusses how life-course immunization could benefit human health at all stages of life. To achieve this, the current vaccination paradigm should be changed and all stakeholders have a role to play. Expert commentary: To enhance immunization confidence in the population, it is essential that stakeholders eliminate complacency toward infectious diseases, improve vaccination convenience, remove barriers among different healthcare specialties, and address prevention as a single entity. They must also consider societal and cultural mindsets by understanding and including public viewpoints. A new "4Cs' model encompassing convenience, confidence, complacency, and cultural acceptance is proposed to convert 'vaccine availability' to 'vaccination acceptance' throughout life. Life-course vaccination should become the new social norm of a healthy life-style, along with a healthy diet, adequate physical exercise, and not smoking. We are 'all in' to make life-course immunization a gateway for all people to lead longer, healthier lives.

Caffeine Treatment for Apnea of Prematurity and the Influence on Dose-Dependent Postnatal Weight Gain Observed Over 15 Years

Background and Aim: To analyze the influence on weight gain of infants exposed to two dosage regimens of oral caffeine citrate (CC) for apnea of prematurity.

Methods: Retrospective descriptive observational study of an eligible very low birth weight cohort over a 15-year period in an Irish University hospital. Data were analyzed between two distinct postnatal ages: 14–28 and 29–56 days.

Results: During the 15-year study, 457 infants were prescribed caffeine. Among the 14–28-day group, after applying exclusion criteria, 418 infants qualified. Two hundred forty-eight infants received 5 mg/(kg·day) and 170 received 10 mg/(kg·day) of CC. Among the 29–56-day group, 362 infants were identified and after applying exclusions, 332 fulfilled entry criteria [214 on 5 mg/(kg·day) and 118 on 10 mg/(kg·day) regimen]. Baseline characteristics of infants were comparable between groups without statistically significant differences. Mean daily weight gain (MDWG) in grams from day 14 to 28 showed a higher rate of increase for the 5 mg/(kg·day) group compared with the 10 mg/(kg·day) group (17.2 ± 12 g vs. 13.0 ± 10.2 g [p = 0.04]). From day 29 to 56, also MDWG was higher among infants on 5 mg/(kg·day) of CC compared with 10 mg/(kg·day) group (15.6 ± 10.8 g vs. 10.2 ± 9.8 g [p = 0.011]).

Conclusion: While a variety of measures are optimized to promote postnatal weight gain of premature infants close to an ideal intrauterine growth curve, not paying sufficient attention to one of the most widely used catabolic agents in neonatology is questionable and warrants vigilance. Additional nutritional measures could be offered to those with prolonged caffeine exposure.

Maternal Vaccination as an Essential Component of Life-Course Immunization and Its Contribution to Preventive Neonatology

Maternal immunisation schedules are increasingly coming under the spotlight as part of the development of lifetime immunisation programmes for the role that they play in improving maternal, foetal, and neonatal health. Maternally-acquired antibodies are critical in protecting infants during the first months of their lives. Maternal immunisation was previously overlooked owing to concerns regarding vaccinations in this untested and high-risk population but is now acknowledged for its potential impact on the outcomes in many domains of foetal and neonatal health, aside from its maternal benefits. This article highlights the role that maternal immunisation may play in reducing infections in preterm and term infants. It explores the barriers to antenatal vaccinations and the optimisation of the immunisation uptake. This review also probes the part that maternal immunisation may hold in the reduction of perinatal antimicrobial resistance and the prevention of non-infectious diseases. Both healthcare providers and expectant mothers should continue to be educated on the importance and safety of the appropriate immunizations during pregnancy. Maternal vaccination merits its deserved priority in a life-course immunization approach and it is perhaps the only immunization whereby two generations benefit directly from a single input. We outline the current recommendations for antenatal vaccinations and highlight the potential advances in the field contributing to “preventive neonatology”.

One Who Came So Young and Early

A poem composed as a reflection of emotions of the parents of an extremely premature baby boy born at 23 weeks of gestation. Sadly we could not sustain his precious life beyond the second day. Staff in the neonatal intensive care units (NICU) offer support to such parents during their difficult times and this poem is a tribute to the caring neonatal clinical professionals and the parents who strive to cope when babies are born at the margins of viability.

Utilization of conventional radiography in a regional neonatal intensive care unit in Ireland

OBJECTIVE

To audit the demand and radiation exposure of conventional radiography in a regional neonatal intensive care unit (NICU) in Ireland.

METHODS

A retrospective study of radiographs performed on all admissions to the NICU in University Maternity Hospital Limerick (UMHL) over 2 years.

RESULTS

A total of 1405 radiographs were performed on 506 infants. 153.5 radiographs per 1000 live births was the observed demand and 44% of radiographs were done out of hours. 47% of all radiographs were performed on infants <1500 g. Median number of radiographs per infant was one (IQR 1-2; range 1-39). Significant negative correlation was observed between number of radiographs and gestational age. Mean lung radiation doses estimated using published values for normal weight (>2500 g), very low birth weight (VLBW), and extremely low birth weight (ELBW) infants based on the median number of chest X-rays were 31.7 µGym, 84.66 and 232.75 µGy, respectively.

CONCLUSIONS

Conventional radiography remains a key diagnostic tool in neonatology particularly in VLBW and ELBW infants and is invaluable in supporting timely clinical decision making. Clinicians should be aware of the cost and potential hazards of neonatal radiography and is recommend that the cumulative radiation exposure among the ELBW and VLBW infants is monitored. Increasing awareness and standardisation of point-of-care ultrasonography could decrease the reliance on conventional radiography in neonatal units.

Margins of viability

A poem reflecting the compassion, conflicts, dilemmas and outcome in the management of an extremely premature 22⁺⁴-week gestation baby girl. Challenges faced by neonatologists in offering optimal care to extremely low birth weight (ELBW) newborn infants and their families is summarised in this poem as an emotional transaction between the clinician and the periviable baby.

The first occurrence of a CTX-M ESBL-producing Escherichia coli outbreak mediated by mother to neonate transmission in an Irish neonatal intensive care unit

BACKGROUND

Escherichia coli (E. coli) comprise part of the normal vaginal microflora. Transfer from mother to neonate can occur during delivery resulting, sometimes, in neonatal bacterial disease. Here, we aim to report the first outbreak of CTX-M ESBL-producing E. coli with evidence of mother-to-neonate transmission in an Irish neonatal intensive care unit (NICU) followed by patient-to-patient transmission.

METHODS

Investigation including molecular typing was conducted. Infection was defined by clinical and laboratory criteria and requirement for antimicrobial therapy with or without positive blood cultures. Colonisation was determined by isolation without relevant symptoms or indicators of infection.

RESULTS

Index case was an 8-day-old baby born at 34 weeks gestation who developed ESBL-producing E. coli infections at multiple body sites. Screening confirmed their mother as colonised with ESBL-producing E. coli. Five other neonates, in the NICU simultaneously with the index case, also tested positive. Of these, four were colonised while one neonate developed sepsis, requiring antimicrobial therapy. The second infected neonate's mother was also colonised by ESBL-producing E. coli. Isolates from all eight positive patients (6 neonates, 2 mothers) were compared using pulsed-field gel electrophoresis (PFGE). Two distinct ESBL-producing strains were implicated, with evidence of transmission between mothers and neonates for both strains. All isolates were confirmed as CTX-M ESBL-producers. There were no deaths associated with the outbreak.

CONCLUSIONS

Resources were directed towards control interventions focused on hand hygiene and antimicrobial stewardship, which ultimately proved successful. Since this incident, all neonates admitted to the NICU have been screened for ESBL-producers and expectant mothers are screened at their first antenatal appointment. To date, there have been no further outbreaks.

Induction of Lactation in the Biological Mother After Gestational Surrogacy of Twins: A Novel Approach and Review of Literature

One of the important challenges in surrogate pregnancies is the early bonding of genetic mother with her infant and the establishment of breastfeeding. A combination of pharmacological and nonpharmacological methods is often used for the induction of lactation. Reports of induced lactation in surrogacy are limited and scattered. In this report, we present a case of induced lactation and initiation of breastfeeding in preterm twins by the genetic mother, through her novel approach after a gestational surrogate pregnancy. Thematic approach of maternal account is summarized with context and rigor. We reviewed the reported literature of induced lactation in similar cases with an aim to address the various methods adopted.

Is It Time for Vaccination to "Go Viral"?

To promote and sustain excellent vaccination coverage, while preserving the key core values of ethics, truth, transparency and trust, the vaccine community should adopt modern digital communication strategies. This article summarizes our views-as experts in multidisciplinary field of vaccinology (consisting of an anthropologist, a public health policy advisor, a vaccine industry expert, a health care journalist and a practicing physician)-which were presented at a satellite symposium held at the 33rd European Society of Paediatric Infectious Disease conference in Leipzig, Germany, in May 2015. This article aims to suggest and recommend strategies to promote vaccination awareness, and highlight proactive measures for building, maintaining and enhancing trust in vaccination through innovative communication and evidence-based interaction with the end user. We believe that converting the results of vaccine research into a successful vaccination program, and replacing misinformation with evidence-based communication, will require a multidisciplinary approach that embraces modern digital and tailored applications to reach out to all populations.

Bed Utilisation in an Irish Regional Paediatric Unit - A Cross-Sectional Study Using the Paediatric Appropriateness Evaluation Protocol (PAEP)

Background: Increasing demand for limited healthcare resources raises questions about appropriate use of inpatient beds. In the first paediatric bed utilisation study at a regional university centre in Ireland, we conducted a cross-sectional study to audit the utilisation of inpatient beds at the Regional Paediatric Unit (RPU) in University Hospital Limerick (UHL), Limerick, Ireland and also examined hospital activity data, to make recommendations for optimal use of inpatient resources.

Methods: We used a questionnaire based on the paediatric appropriateness evaluation protocol (PAEP), modified and validated for use in the United Kingdom, to prospectively gather data regarding reasons for admission and for ongoing care after 2 days, from case records for all inpatients during 11 days in February (winter) and 7 days in May–June (summer). We conducted bivariate and multivariate analysis to explore associations between failure to meet PAEP criteria and patient attributes including age, gender, admission outside of office hours, arrival by ambulance, and private health insurance. Inpatient bed occupancy and day ward activity were also scrutinised.

Results: Mean bed occupancy was 84.1%. In all, 12/355 (3.4%, 95% CI: 1.5%–5.3%) of children failed to meet PAEP admission criteria, and 27/189 (14.3%, 95% CI: 9.3%–19.3%) who were still inpatients after 2 days failed to meet criteria for ongoing care. 35/355 (9.9%, 95% CI: 6.8%–13.0%) of admissions fulfilled only the PAEP criterion for intravenous medications or fluid replacement. A logistic regression model constructed by forward selection identified a significant association between failure to meet PAEP criteria for ongoing care 2 days after admission and admission during office hours (08.00–17.59) (P = .020), and a marginally significant association between this outcome and arrival by ambulance (P = .054).

Conclusion: At a mean bed occupancy of 84.1%, an Irish RPU can achieve 96.6% appropriate admissions. Although almost all inpatients met PAEP criteria, improvements could be made regarding emergency access to social services, management of parental anxiety, and optimisation of access to community-based services. Potential ways to provide nasogastric or intravenous fluid therapy on an ambulatory basis, and outpatient antimicrobial therapy (OPAT) should be explored. Elective surgical admissions should adhere to day-of-surgery admissions (DOSA) policy.

Child Health Care in Ireland

The Irish health care system is based on a complex and costly mix of private, statutory, and voluntary provisions. The majority of health care expenditure comes from the state, with a significant proportion of acute hospital care funded from private insurance, but there are relatively high out-of-pocket costs for most service users. There is free access to acute hospital care, but not for primary care, for all children. About 40% of the population have free access to primary care. Universal preventive public health services, including vaccination and immunization, newborn blood spot screening, and universal neonatal hearing screening are free. Major health challenges include poverty, obesity, drug and alcohol use, and mental health. The health care system has been dominated for the last 5 years by the impact of the current recession, which has led to very sharp cuts in health care expenditure. It is unclear if the necessary substantial reform of the system will happen. Government policy calls for a move toward a patient-centered, primary care-led system, but without very substantial transfers of resources and investment in Information and Communication Technology, this is unlikely to occur.

Combined education and skin antisepsis intervention for persistently high blood-culture contamination rates in neonatal intensive care

Contaminated blood cultures represent challenges regarding diagnosis, duration of hospitalization, antimicrobial use, pharmacy and laboratory costs. Facing problematic neonatal blood culture contamination (3.8%), we instigated a successful intervention combining skin antisepsis using sterile applicators with 2% chlorhexidine gluconate in 70% isopropanol prior to phlebotomy (replacing 70% isopropanol) and staff education. In the six months prior to intervention, 364 neonatal peripheral blood samples were collected. Fourteen (3.8%) were contaminated. In the post-intervention six months, 314 samples were collected. Three (0.96%) were contaminated, representing significant improvement (Fisher's exact test: P = 0.0259). No dermatological sequelae were observed. The improvement has been sustained.

Anomalous left coronary artery from pulmonary artery (ALCAPA) in infants: a 5-year review in a defined birth cohort

Anomalous left coronary artery from pulmonary artery (ALCAPA) is a rare congenital cardiac malformation. It presents predominantly in infancy with features of myocardial ischaemia or cardiac failure and may be mistaken for common paediatric conditions such as colic, reflux or bronchiolitis. With early surgical correction the prognosis is good, but awareness of this condition is essential for prompt diagnosis and referral to a tertiary cardiac centre. In this report we review the five cases that presented during our 5-year study period and discuss the incidence and clinical presentation of ALCAPA among infants. Our observed incidence of 1 in 4243 live births--0.023%--is higher than previously reported. ALCAPA may be more common than previously recognised, and there should be a high index of awareness among paediatricians, paediatric trainees and general practitioners to enable early surgical intervention and improved prognosis for these children.

Infant Staphylococcal Scalded Skin Syndrome, Ireland, 2007 – preliminary outbreak report

Between February and May 2007, five confirmed cases of Staphylococcal Scalded Skin Syndrome (SSSS) were identified in full-term healthy infants born at a maternity unit in Ireland (hospital A). This hospital serves a population of 340,000 people, with over 4,500 babies born annually.

Asplenia in ATR-X syndrome: a second report

Mutation at the ATR-X locus is associated with severe mental retardation. Several conditions, initially reported as clinically distinct phenotypes, have now been attributed to ATR-X mutation. Asplenia, in association with severe mental retardation, has been reported and subsequently demonstrated in one family to be due to ATR-X mutation. We now report on a second instance of a patient presenting with mental retardation and asplenia who has been shown to have a mutation at the ATR-X locus.
