Knowledge, attitudes, and practices of paediatric medical officers and registrars on the developmental origins of health and disease in a tertiary women's and children's hospital.

BACKGROUND: To mitigate the growing burden of non-communicable diseases, doctors training to become paediatricians should be equipped with concepts and knowledge regarding Developmental Origins of Health and Disease (DOHaD). METHODS: We assessed the knowledge, attitudes, and practices (KAP) of medical officers, resident physicians, as well as junior and senior residents practising in the paediatric department of a tertiary women's and children's hospital. This was done through a cross-sectional online survey, with questions developed after focused group discussions with domain experts, and responses based on a 5-point Likert scale. RESULTS: A total of 95 physicians met the inclusion criteria, grouped into Medical Officers (MOs) and Registrars (REGs), and we received a 100% response rate. Results showed that few physicians (n = 22, 23.2%) knew the term DOHaD, and majority rated their colleagues to be inadequately informed (n = 84, 88.4%). Among the physicians, one third (n = 32, 33.7%) were not confident in their ability to counsel patients about initiating healthy feeding practices to prevent future metabolic diseases in their children. However, there was a readiness to be better equipped with DOHaD principles and knowledge, and 95.8% (n = 91) strongly acknowledged the physician's responsibility to optimise early life determinants of cardiometabolic health. CONCLUSION: In conclusion, the findings suggest a poor translation of DOHaD concepts, indicating that bridging the gap between DOHaD research knowledge and clinical application represents an unmet need. These principles should be inculcated early in the professional training of all healthcare providers.

A longitudinal study of breastmilk feeding duration, EEG power and early academic skills.

BACKGROUND: The cognitive benefits of breastfeeding are widely recognized; however, its effects on brain development and later academic skills require further examination. This study aimed to examine the longitudinal relations between breastmilk feeding, neurophysiological changes, and early academic skills. METHODS: In the Growing Up in Singapore Towards healthy Outcomes (GUSTO) birth cohort, breastmilk feeding practices were collected every 3 months from 3 weeks to 18 months postpartum. Resting electroencephalography (EEG) was recorded at 18 months and power spectral density was derived. The outcomes were a set of early academic assessments administered at age 4 (n = 810). Structural equation modelling was used to investigate EEG power as a mediator between breastmilk duration and early academic skills. RESULTS: Breastmilk feeding for ≥12 months was associated with better general knowledge, numeracy, and language at age 4 compared to shorter durations of breastmilk feeding (Cohen's d: 1.53-17.44). Linear regression showed that breastmilk duration was negatively and positively associated with low- (i.e., delta, theta) and high-frequency power (i.e., gamma), respectively (Cohen's f2: 0.03-0.09). After adjusting for demographic and child baseline covariates, a decrease in absolute and relative delta, as well as relative theta was associated with better general knowledge and numeracy (Cohen's f2: 0.16-0.25). Relative delta power provided an indirect path between breastmilk duration and early academic skills (x2: 18.390, p = 0.010; CFI: 0.978; TLI: 0.954; RMSEA: 0.040). CONCLUSIONS: Extended breastmilk feeding is associated with reduced low-frequency power and better early academic skills, suggesting benefits to brain development. Additional research to confirm this finding is warranted.

Breastfeeding Practices and Postpartum Weight Retention in an Asian Cohort.

This study examines relationships between breastfeeding practices and postpartum weight retention (PPWR) at 6 and 12 months postpartum among 379 first-time mothers participating in a clinical trial in Singapore. We categorized feeding modes at 6 months into exclusive breastfeeding, mixed feeding, and exclusive formula feeding. Participants were analyzed in two groups based on their PPWR assessment at 6 and 12 months postpartum, with complete datasets available for each assessment. We calculated PPWR by subtracting pre-pregnancy weight from self-reported weight at 6 and 12 months postpartum, defining substantial PPWR as ≥5 kg retention. Modified Poisson regression models adjusted for potential confounders were performed. At 6 and 12 months, 35% (n = 132/379) and 31% (n = 109/347) of women experienced substantial PPWR, respectively. Compared to exclusive breastfeeding, mixed feeding (risk ratio 1.85; 95% confidence interval 1.15, 2.99) and exclusive formula feeding (2.11; 1.32, 3.28) were associated with a higher risk of substantial PPWR at 6 months. These associations were slightly attenuated at 12 months and appeared stronger in women with pre-pregnancy overweight or obesity. This study suggests that breastfeeding by 6 months postpartum may help mitigate PPWR, particularly with exclusive breastfeeding. It also draws attention to targeted interventions to promote breastfeeding among women with overweight or obesity.

Preliminary assessment of the Healthy Early Life Moments (HELMS) webinars in empowering Developmental Origins of Health and Disease (DOHaD) concept among healthcare professionals - a pragmatic serial cross-sectional study.

OBJECTIVES: The Developmental Origins of Health and Disease (DOHaD) concept has gained prominence in maternal and child health (MCH), emphasizing how early-life factors impact later-life non-communicable diseases. However, a knowledge-practice gap exists in applying DOHaD principles among healthcare professionals. Healthy Early Life Moments in Singapore (HELMS) introduced webinars to bridge this gap and empower healthcare professionals. We aimed to conduct a preliminary assessment to gain early insights into the outreach and effectiveness of the educational initiative offered with the HELMS webinars. METHODS: We employed a pragmatic serial cross-sectional study approach and targeted healthcare professionals involved in MCH care. We also collected and analyzed data on webinar registration and attendance, participants' profession and organizational affiliations, and post-webinar survey responses. RESULTS: The median webinar attendance rate was 59.6 % (25th-75th percentile: 58.4-60.8 %). Nurses represented 68.6 % of attendees (n=2,589 out of 3,774). Post-webinar surveys revealed over 75 % of the participants providing positive responses to 14 out of 15 survey questions concerning content, delivery, applicability to work, and organization. CONCLUSIONS: Assessment of the HELMS webinars provided insight into the outreach and early effectiveness in enhancing healthcare professionals' knowledge and confidence in delivering DOHaD education. Bridging the knowledge-practice gap remains a crucial goal.

Strain-resolved metagenomic analysis of the gut as a reservoir for bloodstream infection pathogens among premature infants in Singapore.

BACKGROUND: Gut dysbiosis contributes to the high risk of bloodstream infection (BSI) among premature infants. Most prior studies of the premature infant gut microbiota were conducted in Western countries and prior to development of current tools for strain-resolved analysis. METHODS: We performed metagenomic sequencing of weekly fecal samples from 75 premature infants at a single hospital in Singapore. We evaluated associations between clinical factors and gut microbiota composition using PERMANOVA and mixed effects linear regression. We used inStrain to perform strain-level analyses evaluating for gut colonization by BSI-causing strains. RESULTS: Median (interquartile range) gestation was 27 (25, 29) weeks, and 63% of infants were born via Cesarean section. Antibiotic exposures (PERMANOVA; R2 = 0.017, p = 0.001) and postnatal age (R2 = 0.015, p = 0.001) accounted for the largest amount of variability in gut microbiota composition. Increasing postnatal age was associated with higher relative abundances of several common pathogens (Enterococcus faecalis: p < 0.0001; Escherichia coli: p < 0.0001; Klebsiella aerogenes: p < 0.0001; Klebsiella pneumoniae: p < 0.0001). Antibiotic exposures were generally associated with lower relative abundances of both frequently beneficial bacteria (e.g., Bifidobacterium species) and common enteric pathogens (e.g., Enterobacter, Klebsiella species). We identified strains identical to the blood culture isolate in fecal samples from 12 of 16 (75%) infants who developed BSI, including all infections caused by typical enteric bacteria. CONCLUSIONS: Antibiotic exposures were the dominant modifiable factor affecting gut microbiota composition in a large cohort of premature infants from South-East Asia. Strain-resolved analyses indicate that the gut is an important reservoir for organisms causing BSI among premature infants.

Watchful waiting versus pharmacological management of small-for-gestational-age infants with hyperinsulinemic hypoglycemia.

Introduction: Given that reports on severe diazoxide (DZX) toxicity are increasing, we aimed to understand if the short-term clinical outcomes of small-for-gestational-age (SGA) infants with hyperinsulinemic hypoglycemia (HH) managed primarily by supportive care, termed watchful waiting (WW), are different from those treated with DZX. Method: A real-life observational cohort study was conducted from 1 September 2014 to 30 September 2020. The WW or DZX management decision was based on clinical and biochemical criteria. We compared central line duration (CLD), postnatal length of stay (LOS), and total intervention days (TIDs) among SGA-HH infants treated with DZX versus those on a WW approach. Fasting studies determined the resolution of HH. Result: Among 71,836 live births, 11,493 were SGA, and 51 SGA infants had HH. There were 26 and 25 SGA-HH infants in the DZX and WW groups, respectively. Clinical and biochemical parameters were similar between groups. The median day of DZX initiation was day 10 of life (range 4-32), at a median dose of 4 mg/kg/day (range 3-10). All infants underwent fasting studies. Median CLD [DZX, 15 days (6-27) vs. WW, 14 days (5-31), P = 0.582] and postnatal LOS [DZX, 23 days (11-49) vs. WW, 22 days (8-61), P = 0.915] were comparable. Median TID was >3-fold longer in the DZX than the WW group [62.5 days (9-198) vs. 16 days (6-27), P < 0.001]. Conclusion: CLD and LOS are comparable between WW and DZX groups. Since fasting studies determine the resolution of HH, physicians should be aware that clinical intervention of DZX-treated SGA-HH patients extends beyond the initial LOS.

Perceptions and acceptance of COVID-19 vaccine among pregnant and lactating women in Singapore: A pre-vaccine rollout cross-sectional study.

Introduction: Vaccination is critical in controlling the coronavirus disease 2019 (COVID-19) pandemic. However, vaccine perception and acceptance among pregnant and lactating women is unknown in Singapore. We aimed to determine the acceptance of COVID-19 vaccination among these two groups of women in Singapore and the factors associated with vaccine acceptance. Methods: We conducted an anonymous, online survey on the perceptions of the COVID-19 vaccine and its acceptance by pregnant and lactating women at a tertiary maternal and child hospital in Singapore from 1 March to 31 May 2021. Information on their demographics and knowledge was collected. These factors were assessed for their relationship with vaccine acceptance. Results: A total of 201 pregnant and 207 lactating women participated. Vaccine acceptance rates in pregnant and lactating women were 30.3% and 16.9%, respectively. Pregnant women who were unsure or unwilling to take the vaccine cited concerns about safety of the vaccine during pregnancy (92.9%), while lactating women were concerned about its potential long-term negative effects on the breastfeeding child (75.6%). Factors that were positively associated with vaccine acceptance included a lower monthly household income or education level, appropriate knowledge regarding vaccine mechanism and higher perceived maternal risk of COVID-19. Most pregnant (70.0%) and lactating women (83.7%) were willing to take the vaccine only when more safety data during pregnancy and breastfeeding were available. Conclusion: COVID-19 vaccine acceptance was low among pregnant and lactating women in Singapore. Addressing the safety concerns when more data are available and education on the mechanism of vaccine action will likely improve acceptance among these women.

Effects of an integrated mobile health lifestyle intervention among overweight and obese women planning for pregnancy in Singapore: protocol for the single-arm healthy early life moments in Singapore (HELMS) study.

INTRODUCTION: Changes in social and lifestyle factors have led to increasing rates of metabolic and mental health problems. We hypothesise that a transformation of the current maternal and child health system is required to deliver interventions that effectively promote a good start to life in populations at risk of metabolic and mental health problems. We describe a single-arm implementation study 'Healthy Early Life Moments in Singapore', which aims to examine whether an integrated lifestyle intervention initiated at preconception and continuing throughout pregnancy and postpartum periods can improve the metabolic and mental health of overweight and obese women, and improve early child growth. METHODS AND ANALYSIS: This single-centre implementation trial is conducted at KK Women's and Children's Hospital, Singapore. The trial aims to recruit 500 women, aged 21-40 years with a body mass index of 25-40 kg/m2 who plan to get pregnant, with interventions delivered before conception, until 18 months postdelivery. Primary outcomes comprise pregnancy rate, maternal metabolic and mental health status. Secondary outcomes include maternal reproductive health, pregnancy outcomes and offspring growth. The intervention will be delivered using a mobile health application, to provide anticipatory guidance, raise awareness and guide goal-setting on lifestyle behaviours that include diet, physical activity, mental wellness and sleep hygiene from preconception to postpartum. Women who conceive within 1 year of recruitment will be followed through pregnancy and studied with their infants at six-time points during the first 18 months of life. Questionnaires, anthropometric measurements and multiple biosamples will be collected at each visit. ETHICS AND DISSEMINATION: The study has been approved by the Centralised Institutional Review Board of SingHealth (2021/2247). Written informed consent will be obtained from all participants. The findings will be published in peer-reviewed journals and disseminated to national and international policy makers. TRIAL REGISTRATION NUMBER: NCT05207059.

A Golden Thread approach to transforming Maternal and Child Health in Singapore.

Maternal and child health (MCH) in Singapore is entering a new phase, with challenges different to those faced 50 years ago. The advancement of medical technologies and access to MCH resources have led to a dramatic fall in maternal and infant mortality rates. However, there has been a steep rise in the rates of obesity and related metabolic diseases. Alongside this is an emerging mental wellness challenge, with one in ten women experience depression across pre-, during and post-pregnancy. Maternal obesity and mental disorders before and during pregnancy not only increase a woman's risk of pregnancy complications, but also result in increased risks in the offspring of childhood obesity, behavioral disorders and later life metabolic disease, catalyzing vicious cycles of disease. Thus, there is a pressing need to transform the current MCH system to address a burgeoning metabolic and mental health challenge for Singapore. Initiating interventions during preconception and continuing into the postpartum has the potential to confer long-term maternal-child benefits, promoting virtuous cycles of health. However, the current MCH system emphasizes antenatal care and lacks focus on the equally, if not more important, preconception, postpartum and inter-pregnancy stages. We describe a new model-of-care framework that integrates a life-course approach to health across preconception, pregnancy and postpartum phases, with the social-ecological model comprising individual, interpersonal, institutional, community and policy as the major targets for health promotion interventions. This "golden thread" approach is being established at the Singapore KK Women's and Children's Hospital (KKH), to address both metabolic and mental health challenges to achieve the goal of a thriving, healthy nation. This new model-of-care is set up in KKH as a pilot program known as Healthy Early Life Moments in Singapore (HELMS). HELMS will reach out to women planning to conceive through coordinated interventions across preconception, pregnancy and postpartum periods. A mobile health platform is being developed to facilitate interventions and engage participants in the program through a digital, personalized and interactive approach. This new model-of-care is designed to secure a population with healthy life cycles, by influencing each life-course, early-in-life, to provide the best start for generations to come.

Risk Factors Predicting the Need for Phototherapy in Glucose 6 Phosphate Dehydrogenase-Deficient Infants in a Large Retrospective Cohort Study.

INTRODUCTION: Glucose 6-phosphate dehydrogenase (G6PD) deficiency increases the risk of severe neonatal hyperbilirubinemia. This study evaluates the risk factors predicting the need for phototherapy in G6PD-deficient neonates after 72 h of age and assesses the safety of early discharge. METHODS: A retrospective cohort study of 681 full-term G6PD-deficient infants with a birth weight ≥2,500 g over 4 years was conducted. We compared the baseline characteristics, bilirubin level on day 4 (after 72 h of life), day of peak bilirubin, G6PD levels, and concomitant ABO incompatibility between the group that required phototherapy (Group A) and those who did not (Group B). RESULTS: 396 infants (58%), predominantly males, required phototherapy in the first week of life. The infants who required phototherapy had a lower median gestational age (38.3 vs. 38.7 weeks, p < 0.01) and had lower G6PD levels (2.3 ± 2.5 vs. 3 ± 3.4 IU, p < 0.05) compared to the controls. The mean day-four total serum bilirubin (TSB) levels were higher (213 ± 32 vs. 151 ± 37 µmol/L, p < 0.01), with bilirubin level peaking earlier (3 vs. 4 days of life, p < 0.01) in group A. Regression analysis identified TSB levels on day 4, Chinese race, lower gestation, and concomitant ABO incompatibility as the significant predictors for the need for phototherapy in the study population. In particular, coexisting ABO blood group incompatibility increased the risk of jaundice requiring phototherapy (OR 4.27, 95% CI: 1.98-121, p < 0.01). Day four TSB values above 180 µmol/L predicted the need for phototherapy with 86% sensitivity and 80% specificity. The findings were similar across both male and female infants with G6PD deficiency. CONCLUSION: G6PD-deficient infants with day four TSB levels of >180 µmol/L (10.5 mg/dL) and associated ABO blood group incompatibility have a higher risk of requiring phototherapy in the first week of life and should be closely monitored.

Neonatal brain and physiological reactivity in preschoolers: An initial investigation in an Asian sample.

Parasympathetic nervous system (PNS) activity is important to physiological regulation. Limbic structures are important in determining what information the PNS receives, potentially influencing concurrent physiological responsivity and, ultimately, shaping PNS development. Yet, whether individual differences in these structures are linked to PNS activity in early childhood remains unclear. Here, in an exploratory capacity, we examined the association between neonatal limbic structures (i.e., the left and right amygdala and hippocampus) and preschoolers' resting-state respiratory sinus arrhythmia (RSA). RSA is a measure of heart-rate variability, a physiological marker that reflects fluctuation in the PNS and is often found predictive of emotion regulation and psychological wellbeing. Data were extracted from the "Growing Up in Singapore towards Healthy Outcomes" (GUSTO) cohort (n = 73, 39 girls). Neonatal limbic volume was collected within two weeks after birth while infants were asleep. Resting-state RSA was collected during a coloring session at 42 months of age. After controlling for potential confounders, a Bonferroni-corrected significant association between neonatal left hippocampal volume and resting-state RSA emerged wherein larger hippocampal volume was associated with higher resting-state RSA. No significant associations were present between resting-state RSA and right or left amygdala, or right hippocampal volume. These findings contribute to an increasing body of evidence aiming at enhancing our understanding of neurobiological underpinnings of parasympathetic activity and modulation. Results are also discussed with reference to ideas concerning biological sensitivity to context, as both left hippocampal volume and resting-state RSA were previously found to moderate associations between adversity and psychological function.

Perinatal Palliative Care Service: Developing a Comprehensive Care Package for Vulnerable Babies with Life Limiting Fetal Conditions.

Background: Perinatal Palliative Care provides comprehensive and holistic care for expectant and new parents, who receive a diagnosis of life-limiting fetal condition and opt to continue pregnancy and care for their newborn infant. Aim: To develop a service providing individually tailored holistic care during pregnancy, birth, postnatal and bereavement period. Methods: Following a baseline survey of neonatologists and discussions with key stakeholders we launched the Perinatal Palliative service at the KK Women's and Children's hospital, Singapore in January 2017. The multidisciplinary team, led by a Palliative care specialist comprised of Obstetricians, Neonatologists, nurses and medical social workers. The Birth defect clinic referred parents with antenatally diagnosed 'Lethal' fetal conditions. The team checked the understanding and the decision making process of parents and initiated and finalized advance care plans. The service also embraced deserving postnatal referrals upon request. Results: A total of 41 cases were seen from January 2017 to December 2019. Of these, 26/41(63%) were referred antenatally and had completed advance care plans. 18/41 (44%) died during or shortly after birth and 10/41(24%) continue to survive and are supported by the community palliative team. During this time a workflow was formulated and modified based on parent and team feedback. Conclusion: Awareness of the service has increased over the years and a clear workflow has been formulated. Advance care plans are prepared and documented before birth so as to enable service teams on board to provide well timed pertinent care. Feedbacks from parents about this service were positive.

Guidance for the clinical management of infants born to mothers with suspected/confirmed COVID-19 in Singapore.

In this paper, we provide guidance to clinicians who care for infants born to mothers with suspected/confirmed COVID-19 during this current pandemic. We reviewed available literature and international guidelines based on the following themes: delivery room management; infection control and prevention strategies; neonatal severe acute respiratory syndrome coronavirus 2 testing; breastfeeding and breastmilk feeding; rooming-in of mother-infant; respiratory support precautions; visiting procedures; de-isolation and discharge of infant; outpatient clinic attendance; transport of infant; and training of healthcare staff. This guidance for clinical care was proposed and contextualised for the local setting via consensus by members of this workgroup and was based on evidence available as of 31 July 2020, and may change as new evidence emerges.

A feed-centric hypoglycaemia pathway ensures appropriate care escalation in at-risk infants.

BACKGROUND: There is a lack of clarity of what constitutes the starting point of a clinical pathway for infants at-risk of hypoglycaemia. Glucose-centric pathways (GCP) identify low glucose in the first 2 hours of life that may not represent clinical hypoglycaemia and can lead to inappropriate glucose management with infusions and medications. OBJECTIVE: To study the impact of a feed-centric pathway (FCP) on the number of admissions for hypoglycaemia to level 2 special care nursery (SCN) and the need for parenteral glucose/medications, compared to GCP. METHODS: This project was conducted over 2 years, before and after switching from a GCP to FCP in our institution. FCP involves skin-to-skin care, early breast feeding, checking glucose at 2 hours and use of buccal glucose. The primary outcome was the number of SCN admissions for hypoglycaemia. Secondary outcomes include the number of infants needing intravenous glucose, medications and length of SCN stay. RESULTS: Of 23 786 live births, 4438 newborns were screened. We screened more infants at-risk for hypoglycaemia using the FCP (GCP:1462/11969, 12.2% vs FCP:2976/11817, 25.1%) but significantly reduced SCN admissions (GCP:246/1462, 16.8% vs FCP:102/2976, 3.4%; p<0.0001). Fewer but proportionally more FCP newborns required intravenous glucose (GCP: 136/246, 55% vs FCP: 88/102, 86%; p=0.000). Compared with GCP, FCP reduced the total duration of stay in SCN by 104 days per annum, reducing the cost of care. However, the mean length of SCN stay for FCP was higher (GCP:2.43 days vs FCP:3.49 days; p=0.001). There were no readmissions for neonatal hypoglycaemia to our institution. CONCLUSION: The use of FCP safely reduced SCN admissions, averted avoidable escalation of care and helped identify infants who genuinely required intravenous glucose and SCN care, allowing more efficient utilisation of healthcare resources.

A synbiotic intervention modulates meta-omics signatures of gut redox potential and acidity in elective caesarean born infants.

BACKGROUND: The compromised gut microbiome that results from C-section birth has been hypothesized as a risk factor for the development of non-communicable diseases (NCD). In a double-blind randomized controlled study, 153 infants born by elective C-section received an infant formula supplemented with either synbiotic, prebiotics, or unsupplemented from birth until 4 months old. Vaginally born infants were included as a reference group. Stool samples were collected from day 3 till week 22. Multi-omics were deployed to investigate the impact of mode of delivery and nutrition on the development of the infant gut microbiome, and uncover putative biological mechanisms underlying the role of a compromised microbiome as a risk factor for NCD. RESULTS: As early as day 3, infants born vaginally presented a hypoxic and acidic gut environment characterized by an enrichment of strict anaerobes (Bifidobacteriaceae). Infants born by C-section presented the hallmark of a compromised microbiome driven by an enrichment of Enterobacteriaceae. This was associated with meta-omics signatures characteristic of a microbiome adapted to a more oxygen-rich gut environment, enriched with genes associated with reactive oxygen species metabolism and lipopolysaccharide biosynthesis, and depleted in genes involved in the metabolism of milk carbohydrates. The synbiotic formula modulated expression of microbial genes involved in (oligo)saccharide metabolism, which emulates the eco-physiological gut environment observed in vaginally born infants. The resulting hypoxic and acidic milieu prevented the establishment of a compromised microbiome. CONCLUSIONS: This study deciphers the putative functional hallmarks of a compromised microbiome acquired during C-section birth, and the impact of nutrition that may counteract disturbed microbiome development. TRIAL REGISTRATION: The study was registered in the Dutch Trial Register (Number: 2838 ) on 4th April 2011.

New BPD-prevalence and risk factors for bronchopulmonary dysplasia/mortality in extremely low gestational age infants ≤28 weeks.

OBJECTIVE: To evaluate prevalence and risk factors of moderate-severe Bronchopulmonary dysplasia (BPD)/Death in extremely low gestation age neonates (ELGANs). STUDY DESIGN: Study of 266 ELGANs born at gestational age (GA) ≤ 28 weeks (w). Primary Outcome measure-composite outcome of moderate-severe BPD/Death using the National Institute of Child Health and Human Development NICHD's (2001) BPD definition. RESULT: Cohort's mean GA and birth-weight (BW) were 25.3 ± 1.4w and 724 ± 14 g respectively with an overall mortality of 19% and moderate-severe BPD of 67%. Prevalence of moderate-severe BPD/death decreased significantly with increasing GA (86-93%) at 23-24 w; to <60% at 27-28w (OR 0.63; 95% CI; 0.52-0.77). On univariate analysis, other risk factors included BW(OR 1.005; 95% CI; 1.003-1.007), Sepsis (OR 2.9; 95% CI, 1.3-6.4), PDA needing treatment (OR 2.2; 95% CI, 1.3-3.9); air leaks (OR 2.7; 95% CI; 1.02-7.3) FiO2 requirement >25%(OR 1.06; 95% CI; 1.01-1.11); and mechanical ventilation(MV) on Day7 (OR5.5; 95% CI; 2.8-10.8). Only need for Day7 MV was independently predictive of composite outcome (OR1.97; 95% CI; 1.3-3.1). CONCLUSION: Risk factor identification will enable initiatives to implement lung protective strategies and develop prospective models for BPD prediction and prognostication.

The association of maternal gestational hyperglycemia with breastfeeding duration and markers of milk production.

BACKGROUND: Previous studies focusing on the association between gestational diabetes and breastfeeding duration have been inconclusive. OBJECTIVES: We aimed to determine whether maternal gestational hyperglycemia is associated with the duration of breastfeeding and the concentrations of markers linked to breastmilk production. METHODS: Data from the prospective, multiethnic Growing Up in Singapore Towards Healthy Outcomes study were used to assess the association of fasting plasma glucose (FPG) and 2-h postglucose challenge (2hPG) measured at 26-28 wk of gestation with duration of breastfeeding and concentrations of protein, lactose, citrate, sodium, potassium, and zinc in breastmilk 3 wk postpartum. RESULTS: Of the 1035 participants, 5.2% and 9.5% had elevated FPG and 2hPG, respectively, consistent with a diagnosis of gestational diabetes mellitus based on International Association of Diabetes and Pregnancy Study Groups criteria. FPG ≥5.1 mmol/L was associated with a crude reduction in median breastfeeding duration of 2.3 mo. In a model adjusted for maternal prepregnancy BMI and intention to breastfeed, FPG ≥5.1 mmol/L predicted earlier termination of any breastfeeding (adjusted HR: 1.47; 95% CI: 1.04, 2.08) but not full breastfeeding (adjusted HR: 1.08; 0.76, 1.55). 2hPG ≥8.5 mmol/L was not significantly associated with the durations of any (adjusted HR: 0.86; 95% CI: 0.62, 1.19) or full (adjusted HR: 0.85; 95% CI: 0.62, 1.18) breastfeeding. Maternal FPG was significantly and positively associated with breastmilk sodium (adjusted coefficient: 1.28; 95% CI: 1.08, 1.51) and sodium-to-potassium ratio (adjusted coefficient: 1.29; 95% CI: 1.08, 1.54) but not with other measured breastmilk components. CONCLUSIONS: Women with FPG ≥5.1 mmol/L during pregnancy breastfeed for a shorter duration. Future work involving measurement of milk production is needed to determine whether low milk production predicts breastfeeding duration among women with elevated FPG. This trial was registered at www.clinicaltrials.gov as NCT01174875.

Human milk banks in the response to COVID-19: a statement of the regional human milk bank network for Southeast Asia and beyond.

BACKGROUND: The World Health Organization (WHO) recommendations on infant feeding in the context of COVID-19 uphold standing recommendations for breastfeeding, non-separation, and skin-to-skin contact, including the use of donor human milk when mother's own milk is not available. INSUFFICIENT GUIDANCE ON THE USE OF DONOR HUMAN MILK AND THE ROLE OF HUMAN MILK BANKS IN THE PANDEMIC RESPONSE: COVID-19 clinical management guidelines in seven countries in Southeast Asia are not aligned with WHO recommendations despite the lack of evidence of transmission through either breastmilk or breastfeeding. The use of safe donor human milk accessed through human milk banks is also insufficiently recommended, even in countries with an existing human milk bank, leading to a gap in evidence-based management of COVID-19. This highlights long-standing challenges as well as opportunities in the safe, equitable, and resilient implementation of human milk banks in the region. CONCLUSIONS: This statement reflects the expert opinion of the Regional Human Milk Bank Network for Southeast Asia and Beyond on the need to revisit national guidelines based on the best evidence for breastfeeding during the COVID-19 pandemic, to incorporate human milk bank services in national obstetric and newborn care guidelines for COVID-19 where possible, and to ensure that operations of human milk banks are adapted to meet the needs of the current pandemic and to sustain donor human milk supply in the long-term. The Network also recommends sustained engagement with the global human milk bank community.
