Postnatal care and acceptability of emollient therapy in very low birthweight infants in Harare, Zimbabwe: a qualitative analysis

BACKGROUND

Preterm birth (birth before 37 completed weeks of pregnancy) is the leading cause of neonatal and child under-five mortality globally, both of which are highest regionally in sub-Saharan Africa. The skin barrier plays a critical role in neonatal health and increasing evidence supports the use of topical emollient therapy to promote postnatal growth and reduce hospital-acquired infections in preterm infants. The World Health Organization (WHO) currently recommends emollient therapy in preterm or low birthweight infants globally but calls for further research on impacts of emollient use, especially in Africa. Little is known about postnatal skincare practices and the tradition of oil massage across sub-Saharan Africa. Further documentation is necessary to understand the context for future emollient intervention trials.

METHODS

61 semi-structured interviews with mothers who just delivered preterm or term infants and 4 focus group discussions (32 participants) with physician and nurse providers of newborn care were conducted at Sally Mugabe Central Hospital (SMCH), in Harare, Zimbabwe. SMCH is the principal public-sector tertiary care hospital for newborn infants in the northern part of the country. Mothers and healthcare professionals were questioned about newborn care at the hospital, current neonatal skincare and bathing practices, and the community's receptivity to a future emollient therapy clinical trial.

RESULTS

Postnatal skincare is centrally important to Zimbabwean communities and petroleum jelly application is nearly universal. The use of cooking oil and other natural oils on infants is also part of traditional customs. The primary needs and desires of mothers who have just given birth to preterm infants are having greater agency in their children's care and financial support in purchasing prescribed medications while at the hospital. Community receptivity to emollient therapy as a cost-effective treatment is high, particularly if mothers are trained to assist with the intervention.

CONCLUSION

Emollient therapy will likely be well-received by communities in and around Harare because of its accordance with current skincare practices and perceptions; however, cultural norms and the experiences of new mothers who have given birth at a facility highlight challenges and considerations for future clinical trial execution.

Neonatal emollient therapy and massage practices in Africa: a scoping review

There have been few reports from Africa on the use and health effects of emollient therapy for newborn infants. We aimed to describe neonatal skin care practices in Africa, and to illuminate opportunities to introduce evidence-based interventions to improve these practices. We conducted a scoping review of the quantitative and qualitative published peer-reviewed and grey literature in English on emollient use in Africa. Outcomes of interest included neonatal skin care practices, with a focus on the application of oils and other products to infant skin, including in association with bathing and massage. We screened 5257 articles and summarised findings from 23 studies-13 qualitative, nine quantitative and one mixed methods-that met our study criteria. Seven studies reported the use of emollients for perceived benefits, including thermal care, treatment for illness, promotion of growth and development, infection reduction, skin condition improvement, spirituality and lubrication to aid massage. Four studies reported the quantitative health impact of skin care product applications, including improvements in skin condition, neurodevelopment and bone growth, as well as a reduction in nosocomial infections. This review highlights opportunities for skin care intervention and future research on neonatal skin care practices in Africa.

Subnational estimates of vitamin A supplementation coverage in children: a geospatial analysis of 45 low- and middle-income countries

OBJECTIVES

Vitamin A supplementation (VAS) can protect children from the adverse health consequences of vitamin A deficiency. Granular data on VAS coverage can guide global and national efforts to achieve universal VAS coverage. To provide geographically precise targeting of VAS programs and to monitor progress in reducing geographic disparities, we aimed to create high-resolution (5 × 5 km2) maps of VAS coverage in children under 5 years across VAS priority countries.

STUDY DESIGN

We used cross-sectional data from the Demographic and Health Surveys (DHS) program.

METHODS

We used data from the DHS program for United Nations Children's Fund -designated VAS priority countries between 2000 and 2017 with data available from 2005 or later. The outcome variable was the proportion of children under 5 years who received a vitamin A dose in each sampled cluster. We applied a Bayesian geostatistical approach incorporating geographic, climatic, and nutritional covariates to estimate VAS coverage for each cell. We estimated and mapped absolute VAS coverage, Bayesian uncertainty intervals, and exceedance probabilities.

RESULTS

Our sample included countries from Latin America and the Caribbean, Asia, and Africa. Most countries had estimated VAS coverage levels <70%, and our exceedance probabilities indicated high certainty that our estimates fell below this threshold in most grid cells. International variations were most notable in the Latin America and the Caribbean region and Africa. Intranational variations were greatest in some South Asian and West and Central African countries.

CONCLUSIONS

These prevalence and exceedance maps, especially used with data on indicators of VAS need, could help to improve equity.

28 NICUs participating in a quality improvement collaborative targeting early-onset sepsis antibiotic use

OBJECTIVE

There is widespread overuse of antibiotics in neonatal intensive care units (NICUs). The objective of this study was to safely reduce antibiotic use in participating NICUs by targeting early-onset sepsis (EOS) management.

STUDY DESIGN

Twenty-eight NICUs participated in this statewide multicenter antibiotic stewardship quality improvement collaborative. The primary aim was to reduce the total monthly mean antibiotic utilization rate (AUR) by 25% in participant NICUs.

RESULT

Aggregate AUR was reduced by 15.3% (p < 0.001). There was a wide range in improvement among participant NICUs. There were no increases in EOS rates or nosocomial infection rates related to the intervention.

CONCLUSION

Participation in this multicenter NICU antibiotic stewardship collaborative targeting EOS was associated with an aggregate reduction in antibiotic use. This study informs efforts aimed at sustaining improvements in NICU AURs.

Acceptability and operational feasibility of community health worker-led home phototherapy treatment for neonatal hyperbilirubinemia in rural Bangladesh

There is an unmet need for phototherapy treatment in low- and middle-income countries (LMICs) to prevent disability and death of newborns with neonatal hyperbilirubinemia. Home phototherapy deployed by community health workers (CHWs) in LMICs may help increase access to essential newborn postnatal care in a more acceptable way for families and lead to an increase in indicated treatment rates for newborns with hyperbilirubinemia. We aimed to investigate the operational feasibility and acceptability of a CHW-led home phototherapy intervention in a rural sub-district of Bangladesh for families and CHWs where home delivery was common and a treatment facility for neonatal hyperbilirubinemia was often more than two hours from households. We enrolled 23 newborns who were ≥ 2 kg in weight and ≥ 35 weeks gestational age, without clinical danger signs, and met the American Academy of Pediatric treatment criteria for phototherapy for hyperbilirubinemia. We employed a mixed-method investigation to evaluate the feasibility and acceptability of home phototherapy through surveys, in-depth interviews and focus group discussions with CHWs, mothers, and grandparents. Mothers and family members found home phototherapy worked well, saved them money, and was convenient and easy to operate. CHWs found it feasible to deploy home phototherapy and identified hands-on training, mHealth job aids, a manageable workload, and prenatal education as facilitating factors for implementation. Feasibility and acceptability concerns were limited amongst parents and included: a lack of confidence in CHWs' skills, fear of putting newborn infants in a phototherapy device, and unreliable home power supply. CHW-led home phototherapy was acceptable to families and CHWs in rural Bangladesh. Further investigation should be done to determine the impact of home phototherapy on treatment rates and on preventing morbidity associated with neonatal hyperbilirubinemia.

Integrating evidence and causal mapping of factors that influence medication decision-making by pregnant women at risk of hypertensive disorder: protocol for a scoping review

INTRODUCTION

In 2018, the American College of Obstetricians and Gynecologists recommended low-dose aspirin to prevent the onset of pre-eclampsia among women who were at high risk. Factors influencing women's acceptance of this recommendation span multiple sectors and levels. Understanding how these factors interact will help stakeholders design effective population-level intervention strategies. Our study aims to identify and map relationships among factors influencing the medication decisions of pregnant women at risk of hypertensive disorders.

METHODS AND ANALYSIS

Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews (PRISMA-ScR) guidelines will be followed for this review. A research librarian developed a comprehensive search strategy to retrieve published and unpublished English studies after 1 January 1980, involving factors that influence pregnant women's uptake and adherence to medication for gestational hypertensive disorders. This literature includes perceptions, patterns, acceptance, refusal, tendencies, probability and service utilisation. We will search PubMed, Embase, Web of Science and CINAHL. Reference lists of the selected papers will be searched manually to identify more relevant studies. A two-stage independent screening, consisting of title and abstract screening, followed by full-text screening, will be conducted by two independent reviewers to identify eligible articles. Extracted data will be recorded in a customised variable extraction form and input into a Microsoft Access database. The PRISMA-ScR will be used to guide the presentation of the results, which will be presented in a table and causal map to demonstrate the relationships between extracted variables and medication uptake and adherence. A conceptual simulation model will be formulated to validate the logic of the relationships between variables and identify knowledge gaps. Lastly, experts and stakeholders will be invited to critique and comment on the results.

ETHICS AND DISSEMINATION

This study does not require ethical approval. The full review results will be presented at a relevant conference and submitted to a peer-reviewed scientific journal for publication.

Gender mainstreaming at 25 years: Toward an inclusive, collaborative, and structured research agenda

Background

Gender mainstreaming has been central to the development agenda for advancing gender equality globally for nearly three decades. We examined key learning across gender mainstreaming models and experiences and assess key successes and challenges in actualising gender mainstreaming's transformative potential, in order to inform future research agendas.

Methods

We reviewed 27 years of peer-reviewed literature on gender mainstreaming (1995-2022) and described scholarly publishing trends on the topic based on a set of 528 articles and bibliographic data retrieved from the Scopus database and supplemental coding. The review provides a thematic synthesis of the extant literature, assessing the evidence base to identify gaps and opportunities for future research and collaboration with practitioners. We also contextualise recent research by tracing common threads of scholarly and practitioner discussions over the last two decades.

Results

Publications on gender mainstreaming have increased, primarily from authors with European and USA academic affiliations and funding. Gender mainstreaming in the health and law and policy sectors has been researched most frequently. Trends in co-authorship suggest increasing collaboration among academics, yet limited collaboration among researchers and practitioners. Widespread low citation counts raise concerns about engagement with the literature. Key challenges in gender mainstreaming identified include conceptual clarity, academic-practitioner disjunctures, politics, leadership and organisational culture, men's roles, intersectionality, monitoring and evaluation, and public health sectoral concerns.

Conclusions

The gender mainstreaming literature has expanded considerably over the last 25 years, yet there remain critical knowledge gaps, theoretical inconsistencies, weak research methods and evaluation processes, and implementation challenges. Funders, researchers, and practitioners have failed to prioritise bridging north-south and academic-practitioner divides in gender mainstreaming policy, programmes, and research. Integration of intersectionality also remains nascent. A more inclusive, collaborative, and structured research agenda on gender mainstreaming is needed to effect greater change in the face of persistent and new challenges. Engaging and empowering regional women's organisations, collaborative learning and research programmes, and joint research and advocacy groups; implementing gender-attuned editorial policies; and incorporating gender mainstreaming in educational curricula are recommended.

Effectiveness of ten-valent pneumococcal conjugate vaccine on invasive pneumococcal disease among children <2 years old: A prospective population-based study in rural Bangladesh

The 10-valent pneumococcal conjugate vaccine (PCV10) was introduced in March 2015 in Bangladesh. In this study, we aimed to estimate the impact of PCV10 on invasive pneumococcal disease (IPD) identified by blood cultures and severe pneumonia identified clinically and its effectiveness on invasive disease caused by vaccine serotypes. We conducted population-based surveillance among children aged 2- <24 months between April 2012 through March 2019 in Mirzapur, a rural sub-district of Bangladesh. We compared incidence of IPD and severe pneumonia before (April 2012 to March 2015) and after (April 2015 to March 2019) the introduction of PCV10. Vaccine effectiveness was measured using an indirect cohort analysis of data from four sentinel sites in which PCV10 vaccination status was compared between children with IPD caused by vaccine serotype vs. non-vaccine serotypes. We identified 24 IPD cases by blood culture and 1,704 severe pneumonia hospitalizations during the surveillance period. IPD incidence in under-2-year-old children fell 25 % (95 % CI: -1.2 % to 76 %; p-value = 0.59) from 106 cases per 100,000 child-years at baseline to 79.3 in April 2018- March 2019. Vaccine serotype-IPD incidence was lower (77 % reduction, 95 % CI: -0.45 % to 96 %; p-value = 0.068) in April 2018 - March 2019 than in the pre-vaccine period (85.7 cases to 19.8/100,000 child-years). A significant decline of 54.0 % (95 % CI: 47.0 % to 59.0 %; p-value < 0.001) was observed in hospitalizations due to severe pneumonia. From indirect cohort analysis, the effectiveness of PCV10 against vaccine serotype IPD was 37 % (95 % CI: -141.0 % to 83.5 %; p = 0.5) after the 1st dose and 63.1 % (95 % CI: -3.3 % to 85.9 %, p = 0.0411) after the 2nd or the 3rd dose. This study demonstrates that PCV10 introduction prevented hospitalizations with severe pneumonia and provided individual protection against vaccine serotypes.

Gender norms in a context of legal pluralism: Impacts on the health of women and girls in Ethiopia

To achieve Sustainable Development Goal 5 for gender equality by 2030, it is crucial for health and development professionals and governmental officials to understand how legal systems empower or oppress populations on the basis of gender worldwide, including opportunities and challenges of statutory provisions created by legal pluralism. Using Ethiopia as a case study, this paper examines how local laws applied in Sharia and Customary Dispute Resolution courts impact gender equality and the health of women and girls inspite of the inculcation of human rights statutes into national legislation, including the Constitution. We identify several key issues with the substantive law and its enforcement. First, laws which have been instituted at the national level to improve gender equally have been poorly enforced at the local level. Second, there is a sustained enforcement of laws that oppress women and that protect male perpetrators of gender-based violations. Third, local courts limit female representation and uphold patriarchy. To improve the health of women and girls, stakeholders must take into consideration the ways in which legal systems uphold harmful gender norms and obstruct and/or advance progress towards equal representation, opportunities, and constitutionally-mandated protections for all.

Separation of Maternal and Newborn Care in US Hospitals: A Systemic Threat to Survival, Health and Well-Being

Through greater understanding of past social, cultural, economic, political, scientific and technological forces which shaped our current health systems to separate mothers and newborn infants, we can begin to devise effective approaches to reshape these systems to meet the needs of mothers and newborn infants today. Medical science and technology have evolved vastly in the last century; however, effects of historical factors persist in our current health care systems, reflected in separate maternal and neonatal care in different departments with distinct guidelines, providers, and treatment locations. This separation prevents maternal-infant skin-to-skin contact and bonding, which significantly affects infant development, well-being, and that of their caregivers. We explore historical precedents for the separation of maternal-newborn care, including the transition from midwifery home care to hospital obstetric care, reasons for the increase in hospital births and hospital nursery development, and the effects of world wars, federal acts, health insurance, rooming-in practices, and the development of medical advances such as antibiotics, on hospital infrastructure. This information is evaluated in the context of modern scientific advancements to show that the conditions which shaped health systems to separate mothers and newborns in the past no longer hold. The insights gained will help to identify strategic actions to reshape health care systems to enable more integrated maternal-newborn care and the practice of Kangaroo Mother Care, and to improve survival outcomes and well-being for mothers, families, and their newborn infants.

In-Hospital Formula Feeding Hindered Exclusive Breastfeeding: Breastfeeding Self-Efficacy as a Mediating Factor

Breastfeeding self-efficacy (BSE), defined as a mother's confidence in her ability to breastfeed, has been confirmed to predict the uptake of exclusive breastfeeding (EBF). Early experiences during the birth hospital stay, especially in-hospital formula feeding (IHFF), can impact both EBF and maternal breastfeeding confidence. Therefore, our objective was to examine the association between IHFF and EBF outcomes and investigate whether this association is influenced by BSE. The study included 778 infants from a larger cohort study conducted in 2021, with a one-year follow-up in rural areas of Sichuan Province, China. We used a causal mediation analysis to estimate the total effect (TE), natural direct (NDE), and nature indirect effects (NIE) using the paramed command in Stata. Causal mediation analyses revealed that IHFF was negatively associated with EBF (TE odds ratio = 0.47; 95% CI, 0.29 to 0.76); 28% of this association was mediated by BSE. In the subgroup analysis, there were no significant differences in the effects between parity subgroups, as well as between infant delivery subgroups. Our study found that IHFF hindered later EBF and that BSE mediated this association. Limiting the occurrence of in-hospital formula feeding or improving maternal breastfeeding self-efficacy is likely to improve exclusive breastfeeding outcomes.

Strengthening theories of change in women's group interventions to improve learning

Background

Supporting women's groups is increasingly seen as an important intervention strategy for advancing women's empowerment, economic outcomes, and family health in low- and middle-income countries. We argue that learning from investments in women's group platforms is often limited by the lack of a well-articulated, evaluable theory of change (ToC) developed by those designing the programmes.

Methods

We first identify a simple set of steps important to specifying a ToC that is evaluable and supports learning (what could be done). We then propose a framework in which we hope social scientists can find a common starting point (reconciling what could be and is being done). The framework emphasises identifying untested assumptions around pathways for introducing and adopting new knowledge, opportunities, technologies, interventions or implementation approaches, and pathways from group participation to behaviour change. Finally, we apply this framework to a portfolio of 46 women's groups investments made by the Bill and Melinda Gates Foundation between 2005 and 2017 to understand the prevalence and clarity of their grantees' theories of change (some of what is done).

Results

The majority of the investment documents reviewed did not make clear the embedded assumptions or hypothesised pathways from decisions to join a group, to women's group participation, to behaviour change and and whether pathways are connected or work independently.

Conclusions

We use an example from an actual investment to illustrate how this framework can support accounting for assumptions in the ToC used to guide the evaluation, the testing and measuring of mechanisms assumed to be driving behaviour change and disentangling the effects of implementationfrom context. A ToC for group-based programmes should specify in what capacities the group-based model is essential to the hypothesised pathways of impact vs. its role as an efficient delivery mechanism for programmes that would potentially generate impacts even if delivered directly to individuals. In addition, without fully specifying the motivation for individuals to change behaviour in terms of their risk/return calculus and testing underlying assumptions, we miss an opportunity to better understand the pathways for how the programme influences or fails to influence individuals' health behaviours. However, fully specifying (and measuring) every link in the programme's ToC is not costless. We present suggestions for developing ToCs with testable hypotheses that foster learning about why a women's group intervention achieved or failed to achieve its intended impact.

Variation in rates of sexual assault crisis counsellor usage during forensic examination in California: an observational study

OBJECTIVES

A critical asset to post-assault care of survivors is support from sexual assault crisis counsellors (SACCs). We sought to elucidate variation in implementation between California counties in SACC accompaniment during Sexual Assault Forensic Examination (SAFE).

METHODS

SACC attendance data from 2019 was obtained from the California Governor's Office of Emergency Services (CalOES). To assess SACC attendance rates during SAFEs, we requested SAFE quantity data from sheriffs and public health departments, the State Forensic Bureau, and the California Department of Justice (DOJ), but all requests were unanswered or denied. We also sought SAFE data from District Attorneys (DAs) in each county, and received responses from Marin and Contra Costa Counties. To estimate numbers of SAFEs per county, we gathered crime statistics from the Federal Bureau of Investigation's (FBI's) Uniform Crime Reporting Program and OpenJustice, a transparency initiative by the California DOJ. For each data source, we compared SACC attendance to SAFE quantities and incidences of sexual assault statewide.

RESULTS

At the state level, data on SACC attendance per CalOES and DOJ archival data on sexual assault were used to approximate relative rates of SACC accompaniment at SAFEs; 83% (30 of 36) of counties had values <50%. The joint sexual assault crisis centre for Contra Costa and Marin Counties reported that 140 SACCs were dispatched in 2019, while DAs in Contra Costa and Marin reported completion of 87 SAFEs in 2019, for a calculated SACC accompaniment rate of 161%. Proxy data sourced from FBI and DOJ crime statistics displayed significant inconsistencies, and DOJ data was internally inconsistent.

CONCLUSIONS

SACC accompaniment at SAFEs appears to be low in most California counties, however, limited data accessibility and data discrepancies and inaccuracies (e.g., rates over 100%) prevented reliable determination of SACC accompaniment rates during SAFEs. Substantial improvements in data accuracy and transparency are needed to ensure survivors' adequate access to resources.

Effects of an educational planetary plate graphic on meat consumption in a Stanford University dining hall: a randomized controlled trial

BACKGROUND

Assess the impact of an educational Planetary Health Plate (PHP) graphic on meat-related dietary choices of Stanford University dining hall patrons using a randomized controlled trial crossover design. All patrons entering the dining hall during study periods were enrolled as participants. Control, n = 631; PHP, n = 547.

METHODS

Compare dietary behavior without signage to behavior while exposed to PHP during four equivalent dinner meals. The primary outcome was total meat-dish weight adjusted for the number of people entering the dining hall. Secondary outcomes included the number of meat-dish servings and average meat-dish serving weight. Analysis using T-tests, Poisson generalized linear model.

RESULTS

Differences in total meat-dish weight, (1.54 kg; 95% Confidence Interval [CI] = -4.41,1.33; P = .19) and average meat-dish serving weight (0.03 kg; 95% CI = 0.00, 0.06; P = .07) between PHP and control patrons did not reach significance. The rate at which PHP patrons took meat was significantly lower (Incidence Rate Ratio 0.80; 95% CI = 0.71, 0.91; P < .001).

CONCLUSION

Exposure to an educational plate graphic decreased the proportion of patrons taking meat but had no impact on total meat consumption or meat-dish serving weight. Statistical methods used in this study may inform future investigations on dietary change in the dining hall setting. Further research on the role of educational signage in influencing dietary behavior is warranted, with an aim to improve human health and environmental sustainability.

The burden of antimicrobial resistance in the Americas in 2019: a cross-country systematic analysis

Background

Antimicrobial resistance (AMR) is an urgent global health challenge and a critical threat to modern health care. Quantifying its burden in the WHO Region of the Americas has been elusive-despite the region's long history of resistance surveillance. This study provides comprehensive estimates of AMR burden in the Americas to assess this growing health threat.

Methods

We estimated deaths and disability-adjusted life-years (DALYs) attributable to and associated with AMR for 23 bacterial pathogens and 88 pathogen-drug combinations for countries in the WHO Region of the Americas in 2019. We obtained data from mortality registries, surveillance systems, hospital systems, systematic literature reviews, and other sources, and applied predictive statistical modelling to produce estimates of AMR burden for all countries in the Americas. Five broad components were the backbone of our approach: the number of deaths where infection had a role, the proportion of infectious deaths attributable to a given infectious syndrome, the proportion of infectious syndrome deaths attributable to a given pathogen, the percentage of pathogens resistant to an antibiotic class, and the excess risk of mortality (or duration of an infection) associated with this resistance. We then used these components to estimate the disease burden by applying two counterfactual scenarios: deaths attributable to AMR (compared to an alternative scenario where resistant infections are replaced with susceptible ones), and deaths associated with AMR (compared to an alternative scenario where resistant infections would not occur at all). We generated 95% uncertainty intervals (UIs) for final estimates as the 25th and 975th ordered values across 1000 posterior draws, and models were cross-validated for out-of-sample predictive validity.

Findings

We estimated 569,000 deaths (95% UI 406,000-771,000) associated with bacterial AMR and 141,000 deaths (99,900-196,000) attributable to bacterial AMR among the 35 countries in the WHO Region of the Americas in 2019. Lower respiratory and thorax infections, as a syndrome, were responsible for the largest fatal burden of AMR in the region, with 189,000 deaths (149,000-241,000) associated with resistance, followed by bloodstream infections (169,000 deaths [94,200-278,000]) and peritoneal/intra-abdominal infections (118,000 deaths [78,600-168,000]). The six leading pathogens (by order of number of deaths associated with resistance) were Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Streptococcus pneumoniae, Pseudomonas aeruginosa, and Acinetobacter baumannii. Together, these pathogens were responsible for 452,000 deaths (326,000-608,000) associated with AMR. Methicillin-resistant S. aureus predominated as the leading pathogen-drug combination in 34 countries for deaths attributable to AMR, while aminopenicillin-resistant E. coli was the leading pathogen-drug combination in 15 countries for deaths associated with AMR.

Interpretation

Given the burden across different countries, infectious syndromes, and pathogen-drug combinations, AMR represents a substantial health threat in the Americas. Countries with low access to antibiotics and basic health-care services often face the largest age-standardised mortality rates associated with and attributable to AMR in the region, implicating specific policy interventions. Evidence from this study can guide mitigation efforts that are tailored to the needs of each country in the region while informing decisions regarding funding and resource allocation. Multisectoral and joint cooperative efforts among countries will be a key to success in tackling AMR in the Americas.

Research priorities for care of preterm or low birth weight infants: health policy

Research priorities for preterm or low birth weight (LBW) infants were advanced in 2012, and other research priority-setting exercises since then have included more limited, context-specific research priorities pertaining to preterm infants. While developing new World Health Organization (WHO) guidelines for care of preterm or LBW infants, we conducted a complementary research prioritisation exercise. A diverse, globally representative guideline development group (GDG) of experts - all authors of this paper along with WHO steering group for preterm-LBW guidelines - was assembled by the WHO to examine evidence and consider a variety of factors in intervention effectiveness and implementation, leading to 25 new recommendations and one good practice statement for care of preterm or LBW infants. The GDG generated research questions (RQs) based on contributions to improvements in care and outcomes of preterm or LBW infants, public health impacts, answerability, knowledge gaps, feasibility of implementation, and promotion of equity, and then ranked the RQs based on their likelihood to further change or influence the WHO guidelines for the care of preterm or LBW infants in the future. Thirty-six priority RQs were identified, 32 (89%) of which focused on aspects of intervention effectiveness, and the remaining four addressed implementation ("how") questions. Of the top 12 RQs, seven focused on further advancing new recommendations - such as family involvement and support in caring for preterm or LBW infants, emollient therapy, probiotics, immediate KMC for critically ill newborns, and home visits for post-discharge follow-up of preterm or LBW infants - and three RQs addressed issues of feeding (breastmilk promotion, milk banks, individualized feeding). RQs prioritised here will be critical for optimising the effectiveness and delivery of new WHO recommendations for care of preterm or LBW infants. The RQs encompass unanswered research priorities for preterm or LBW infants from prior prioritisation exercises which were conducted using Child Health and Nutrition Research Initiative (CHNRI) methodology.

New World Health Organization recommendations for care of preterm or low birth weight infants: health policy

Approximately 11% of infants are born preterm, and complications of prematurity are the most common cause of death in children aged under five years. Almost one million preterm infants die each year across low, high and middle income countries. In 2021, the World Health Organization (WHO) convened a Guideline Development Group (GDG) to examine evidence and formulate recommendations for care of preterm or low birthweight (LBW) infants according to WHO Guideline Review Committee (GRC) criteria. GRADE methods were used to assess the certainty of evidence and the GDG developed judgements using the DECIDE (Developing and Evaluating Communication strategies to support Informed Decisions and practice based on Evidence) framework. Twenty-five recommendations were made; 11 recommendations were new, and 16 were for preventive and promotive care. Kangaroo Mother Care (KMC) was recommended to start immmediately after birth as routine care for all preterm or LBW newborns (except for critically ill infants who are in shock, unable to breath spontaneously after resuscitation, or require ventilatory support) both in the facility and at home. New recommendations were also made for caffeine to treat apnoea and for extubation; family involvement in routine care for preterm or LBW infants; and for post-discharge home-visit follow-up care. New recommendations were also made to consider use of probiotics, emollient therapy, caffeine for prevention of apnoea, continuous positive airway pressure (CPAP) immediately after birth (with or without respiratory distress) in infants less than 32 weeks gestational age; and for family support to enable the care of preterm or LBW infants. The recommendations confirm the pivotal role of preventive and promotive care for preterm and LBW infants, especially the importance of keeping the baby and mother together, and empowering and supporting families to care for their preterm or LBW infant. WHO is now working to help scale up care for small and sick newborns, including organizational shifts in all 'health system building blocks' such as infrastructure, commodities, workforce and monitoring.

Comparative predictive power of serum vs plasma proteomic signatures in feto-maternal medicine

BACKGROUND

Blood proteins are frequently measured in serum or plasma, because they provide a wealth of information. Differences in the ex vivo processing of serum and plasma raise concerns that proteomic health and disease signatures derived from serum or plasma differ in content and quality. However, little is known about their respective power to predict feto-maternal health outcomes. Predictive power is a sentinel characteristic to determine the clinical use of biosignatures.

OBJECTIVE

This study aimed to compare the power of serum and plasma proteomic signatures to predict a physiological pregnancy outcome.

STUDY DESIGN

Paired serum and plasma samples from 73 women were obtained from biorepositories of a multinational prospective cohort study on pregnancy outcomes. Gestational age at the time of sampling was the predicted outcome, because the proteomic signatures have been validated for such a prediction. Multivariate and cross-validated models were independently derived for serum and plasma proteins.

RESULTS

A total of 1116 proteins were measured in 88 paired samples from 73 women with a highly multiplexed platform using proximity extension technology (Olink Proteomics Inc, Watertown, MA). The plasma proteomic signature showed a higher predictive power (R=0.64; confidence interval, 0.42-0.79; P=3.5×10^-6) than the serum signature (R=0.45; confidence interval, 0.18-0.66; P=2.2×10^-3). The serum signature was validated in plasma with a similar predictive power (R=0.58; confidence interval, 0.34-0.75; P=4.8×10^-5), whereas the plasma signature was validated in serum with reduced predictive power (R=0.53; confidence interval, 0.27-0.72; P=2.6×10^-4). Signature proteins largely overlapped in the serum and plasma, but the strength of association with gestational age was weaker for serum proteins.

CONCLUSION

Findings suggest that serum proteomics are less informative than plasma proteomics. They are compatible with the view that the partial ex-vivo degradation and modification of serum proteins during sample processing are an underlying reason. The rationale for collecting and analyzing serum and plasma samples should be carefully considered when deriving proteomic biosignatures to ascertain that specimens of the highest scientific and clinical yield are processed. Findings suggest that plasma is the preferred matrix.

To design a health system model for scaling-up Kangaroo mother care (KMC) and assess its impact on the population-level coverage and quality of KMC in Uttar Pradesh, India.

METHODS

We co-developed the model with mothers and health system stakeholders using human-centred design over multiple cycles of implementation, learning and data-driven refinement. Infants with birthweight <2000 g in the study district were prospectively followed to assess the 'effective coverage' of KMC. Effective coverage referred to the proportion of eligible infants receiving ≥8 h of daily skin-to-skin contact and exclusive breastfeeding.

RESULTS

High delivery load facilities were equipped with a KMC Lounge to ensure comfort, respectful care of mothers and high-quality KMC over prolonged periods. Systems to ensure weighing at birth, referral of infants with birthweight <2000 g to KMC facilities, initiation of KMC for all stable low birthweight infants, improving quality of care within KMC facilities and supporting families to continue KMC at home post discharge, were integrated into existing services. KMC was initiated in 93.3% of eligible infants with effective coverage of 52.7% and 64.8% at discharge and 7 days post discharge, respectively.

CONCLUSION

The model addressed critical barriers to KMC implementation and adoption, contributing to its scale-up across the state.

Associations of in-hospital postpartum feeding experiences with exclusive breastfeeding practices among infants in rural Sichuan, China

BACKGROUND

In rural China, exclusive breastfeeding (EBF) prevalence is low and hospitals often fail to attain baby-friendly feeding objectives, such as ≥ 75% of newborns exclusively breastfed from birth to discharge. Empirical evidence for the impact of increased hospital compliance with recommended feeding guidelines on continued EBF in rural China is lacking. We sought to measure and model the association of newborns' in-hospital feeding experiences with EBF practice in infancy to inform policies for EBF promotion.

METHODS

Data were cross-sectional from 785 caregivers of infants < 6 months of age, collected from November to December 2019 in four underdeveloped counties/districts in Sichuan Province. In-hospital feeding practices were determined, and prevalence of current infant feeding practices was calculated from 24-h recall and categorized according to WHO/UNICEF Infant and Young Child Feeding categories as EBF, breastfed with non-milk liquids, mixed feeding, breastfed with solids, and not breastfed. Relative risk ratios were estimated using adjusted multinomial logistic regression to examine risk factors for non-EBF practices compared to EBF, including in-hospital feeding experiences. The regression model was used to investigate change in EBF prevalence under alternative in-hospital experiences.

RESULTS

Only 38.1% of under-six-month-old infants were being exclusively breastfed when data were collected; 61.8% and 77.6% had been fed water and infant formula, respectively, in the hospital. Infants who were fed water or formula before discharge were estimated as 2-3 times as likely to be non-EBF than EBF up to age six months. According to our model, EBF prevalence would have increased to 53.7% (95% confidence interval (CI) 46.1, 61.2) had ≥ 75% of infants been exclusively breastfed and water-based feeds eliminated in-hospital.

CONCLUSIONS

Given the importance of infants' first feeding experiences in the establishment and continuation of EBF, it is imperative that rural Chinese hospitals actively seek to limit infant formula feeds to medically indicated situations and eliminate water-based feeds.

Development of a Urine Metabolomics Biomarker-Based Prediction Model for Preeclampsia during Early Pregnancy

Preeclampsia (PE) is a condition that poses a significant risk of maternal mortality and multiple organ failure during pregnancy. Early prediction of PE can enable timely surveillance and interventions, such as low-dose aspirin administration. In this study, conducted at Stanford Health Care, we examined a cohort of 60 pregnant women and collected 478 urine samples between gestational weeks 8 and 20 for comprehensive metabolomic profiling. By employing liquid chromatography mass spectrometry (LCMS/MS), we identified the structures of seven out of 26 metabolomics biomarkers detected. Utilizing the XGBoost algorithm, we developed a predictive model based on these seven metabolomics biomarkers to identify individuals at risk of developing PE. The performance of the model was evaluated using 10-fold cross-validation, yielding an area under the receiver operating characteristic curve of 0.856. Our findings suggest that measuring urinary metabolomics biomarkers offers a noninvasive approach to assess the risk of PE prior to its onset.

Multiomic signals associated with maternal epidemiological factors contributing to preterm birth in low- and middle-income countries

Preterm birth (PTB) is the leading cause of death in children under five, yet comprehensive studies are hindered by its multiple complex etiologies. Epidemiological associations between PTB and maternal characteristics have been previously described. This work used multiomic profiling and multivariate modeling to investigate the biological signatures of these characteristics. Maternal covariates were collected during pregnancy from 13,841 pregnant women across five sites. Plasma samples from 231 participants were analyzed to generate proteomic, metabolomic, and lipidomic datasets. Machine learning models showed robust performance for the prediction of PTB (AUROC = 0.70), time-to-delivery (r = 0.65), maternal age (r = 0.59), gravidity (r = 0.56), and BMI (r = 0.81). Time-to-delivery biological correlates included fetal-associated proteins (e.g., ALPP, AFP, and PGF) and immune proteins (e.g., PD-L1, CCL28, and LIFR). Maternal age negatively correlated with collagen COL9A1, gravidity with endothelial NOS and inflammatory chemokine CXCL13, and BMI with leptin and structural protein FABP4. These results provide an integrated view of epidemiological factors associated with PTB and identify biological signatures of clinical covariates affecting this disease.

Perceptions, beliefs, and current practices regarding neonatal skin care and emollient use in eastern Uganda: a qualitative study

BACKGROUND

The skin is a major route of infection in the neonatal period, especially in low birthweight (LBW) infants. Appropriate and safe neonatal skin care practices are required to reduce this risk. The perceptions and beliefs of mothers and other caregivers towards various neonatal skin care practices in our setting have been documented. Data from Asia suggests that the application of emollient to the skin of LBW infants can promote growth, reduce serious neonatal infections, and potentially reduce mortality. This is the first study to explore the acceptability of emollients and massage as part of neonatal skin care in a low-resource setting in sub-Saharan Africa (SSA) that is representative of the majority of government health facilities in Uganda and many in SSA.

OBJECTIVE

To explore perceptions, beliefs, and current practices regarding neonatal skin care and emollient use in eastern Uganda.

METHODS

We conducted a qualitative study consisting of three focus group discussions (30 participants), eight in-depth interviews with mothers/caregivers of preterm and term neonates and 12 key informant interviews with midwives, doctors and community health workers involved in neonatal care, to explore the perceptions and practices surrounding neonatal skin care and emollient use. Data collected were transcribed and analyzed using thematic content analysis.

RESULTS

Mothers perceived that skin care began in utero. Skincare practices depended on the place of delivery; for deliveries in a health facility the skincare practices were mainly based on the health worker's advice. Vernix caseosa was often washed off due to its perceived undesirability and was attributed to sexual intercourse in the last trimester. Despite their deleterious attributes found in previous studies, petrolatum-based oils, petrolatum-based jellies and talcum baby powders were the most commonly reported items used in neonatal skin care. In our population, there was high acceptability of emollient therapy use; however, neonatal massage was treated with scepticism as mothers feared damaging the vulnerable neonate. Mothers suggested massage and emollient application be undertaken by health workers, if it becomes an intervention.

CONCLUSIONS

In eastern Uganda, the perceptions and beliefs of mothers/caregivers toward neonatal skincare influenced their practices of which some could potentially be beneficial, and others harmful. Emollient use would be easily accepted if adequate sensitisation is conducted and using the gatekeepers such as health workers.

Feasibility and acceptability of home-based neonatal hyperbilirubinemia screening by community health workers using transcutaneous bilimeters in Bangladesh

BACKGROUND

Universal screening for neonatal hyperbilirubinemia risk assessment is recommended by the American Academy of Pediatrics to reduce related morbidity. In Bangladesh and in many low- and middle-income countries, there is no screening for neonatal hyperbilirubinemia. Furthermore, neonatal hyperbilirubinemia may not be recognized as a medically significant condition by caregivers and community members. We aimed to evaluate the acceptability and operational feasibility of community health worker (CHW)-led, home-based, non-invasive neonatal hyperbilirubinemia screening using a transcutaneous bilimeter in Shakhipur, a rural subdistrict in Bangladesh.

METHODS

We employed a two-step process. In the formative phase, we conducted eight focus group discussions with parents and grandparents of infants and eight key informant interviews with public and private healthcare providers and managers to explore their current knowledge, perceptions, practices, and challenges regarding identification and management of neonatal hyperbilirubinemia. Next, we piloted a prenatal sensitization intervention and home-based screening by CHWs using transcutaneous bilimeters and evaluated the acceptability and operational feasibility of this approach through focus group discussions and key informant interviews with parents, grandparents and CHWs.

RESULTS

Formative findings identified misconceptions regarding neonatal hyperbilirubinemia causes and health risks among caregivers in rural Bangladesh. CHWs were comfortable with adoption, maintenance and use of the device in routine home visits. Transcutaneous bilimeter-based screening was also widely accepted by caregivers and family members due to its noninvasive technique and immediate display of findings at home. Prenatal sensitization of caregivers and family members helped to create a supportive environment in the family and empowered mothers as primary caregivers.

CONCLUSION

Adopting household neonatal hyperbilirubinemia screening in the postnatal period by CHWs using a transcutaneous bilimeter is an acceptable approach by both CHWs and families and may increase rates of screening to prevent morbidity and mortality.

Public leadership for gender equality: A framework and capacity development approach for gender transformative policy change

Public leadership is essential in social change, and pivotal in transforming social and institutional norms related to gender inequality, going well beyond equal representation. It must embrace the potential for all public health leaders, of all genders, to become agents of change who challenge gender injustices and institutionalise gender transformative policies and programmes in public health. To support officials, initially in Ethiopia, and catalyse transformative change, we created a new framework and capacity development approach - Public Leadership for Gender Equality (PL4GE) - which can be customised to respond to each country's context. Drawing from three areas of leadership thought - public, transformative, and feminist leadership - PL4GE takes a public values approach in positioning gender equality as a human right, a common good, and a means to improve health outcomes. PL4GE promotes six key leadership practices - defining purpose and articulating vision, co-creating public value, empowering people, fostering strategic partnerships, navigating power, and embodying personal commitment - and guides public leaders through a capacity development journey of change, facilitating them to identify and activate opportunities for gender transformative change in their work and in turn, more broadly within the public whom they serve.

Effect of the mHealth-supported Healthy Future programme delivered by community health workers on maternal and child health in rural China: study protocol for a cluster randomised controlled trial

INTRODUCTION

Millions of young rural children in China still suffer from poor health and malnutrition, partly due to a lack of knowledge about optimal perinatal and child care among rural mothers and caregivers. Meanwhile, there is an urgent need to improve maternal mental health in rural communities. Comprehensive home visiting programmes delivered by community health workers (CHWs) can bridge the caregiver knowledge gap and improve child health and maternal well-being in low-resource settings, but the effectiveness of this approach is unknown in rural China. Additionally, grandmothers play important roles in child care and family decision-making in rural China, suggesting the importance of engaging multiple caregivers in interventions. The Healthy Future programme seeks to improve child health and maternal well-being by developing a staged-based curriculum that CHWs deliver to mothers and caregivers of young children through home visits with the assistance of a tablet-based mHealth system. This protocol describes the design and evaluation plan for this programme.

METHODS AND ANALYSIS

We designed a cluster-randomised controlled trial among 119 rural townships in four nationally designated poverty counties in Southwestern China. We will compare the outcomes between three arms: one standard arm with only primary caregivers participating in the intervention, one encouragement arm engaging primary and secondary caregivers and one control arm with no intervention. Families with pregnant women or infants under 6 months of age are invited to enrol in the 12-month study. Primary outcomes include children's haemoglobin levels, exclusive breastfeeding rates and dietary diversity in complementary feeding. Secondary outcomes include a combination of health, behavioural and intermediate outcomes.

ETHICS AND DISSEMINATION

Ethical approval has been provided by Stanford University, Sichuan University and the University of Nevada, Reno. Trial findings will be disseminated through national and international peer-reviewed publications and conferences.

We call for policy change, education, and advocacy to halt further deterioration of planetary health and for specific measures to prevent the negative effects of climate and environmental change on children's health. We offer an agenda for research, policy change, and healthcare practices to improve the resilience of pediatric populations in the face of climate change.

Early prediction and longitudinal modeling of preeclampsia from multiomics

Preeclampsia is a complex disease of pregnancy whose physiopathology remains unclear. We developed machine-learning models for early prediction of preeclampsia (first 16 weeks of pregnancy) and over gestation by analyzing six omics datasets from a longitudinal cohort of pregnant women. For early pregnancy, a prediction model using nine urine metabolites had the highest accuracy and was validated on an independent cohort (area under the receiver-operating characteristic curve [AUC] = 0.88, 95% confidence interval [CI] [0.76, 0.99] cross-validated; AUC = 0.83, 95% CI [0.62,1] validated). Univariate analysis demonstrated statistical significance of identified metabolites. An integrated multiomics model further improved accuracy (AUC = 0.94). Several biological pathways were identified including tryptophan, caffeine, and arachidonic acid metabolisms. Integration with immune cytometry data suggested novel associations between immune and proteomic dynamics. While further validation in a larger population is necessary, these encouraging results can serve as a basis for a simple, early diagnostic test for preeclampsia.

Improving the precision of maternal, newborn, and child health impact through geospatial analysis of the association of contextual and programmatic factors with health trends in Bihar, India

Background

There is a scarcity of research that comprehensively examines programme impact from a context-specific perspective. We aimed to determine the conditions under which the Bihar Technical Support Programme led to more favourable outcomes for maternal and child health in Bihar.

Methods

We obtained block-level data on maternal and child health indicators during the state-wide scale-up of the pilot Ananya programme and data on health facility readiness, along with geographical and sociodemographic variables. We examined the associations of these factors with increases in the levels of indicators using multilevel logistic regression, and the associations with rates of change in the indicators using Bayesian Hierarchical modelling.

Results

Frontline worker (FLW) visits between 2014-2017 were more likely to increase in blocks with better night lighting (odds ratio (OR) = 1.23, 95% confidence interval (CI) = 1.01-1.51). Birth preparedness increased in blocks with increasing FLW visits (OR = 3.43, 95% CI = 1.15-10.21), while dry cord care practice increased in blocks where satisfaction with FLW visits was increasing (OR = 1.52, 95% CI = 1.10-2.11). Age-appropriate frequency of complementary feeding increased in blocks with higher development index (OR = 1.55, 95% CI = 1.16-2.06) and a higher percentage of scheduled caste or tribe (OR = 3.21, 95% CI = 1.13-9.09). An increase in most outcomes was more likely in areas with lower baseline levels.

Conclusions

Contextual factors (eg, night lighting and development) not targeted by the programme and FLW visits were associated with favourable programme outcomes. Intervention design, including intervention selection for a particular geography, should be modified to fit the local context in the short term. Expanding collaborations beyond the health sector to influence modifiable contextual factors in the long term can result in a higher magnitude and more sustainable impact.

Maternal gender discrimination and child emotional and behavioural problems: A population-based, longitudinal cohort study in the Czech Republic

BACKGROUND

Gender discrimination may be a novel mechanism through which gender inequality negatively affects the health of women and girls. We investigated whether children's mental health varied with maternal exposure to perceived gender discrimination.

METHODS

Complete longitudinal data was available on 2,567 mother-child dyads who were enrolled between March 1, 1991 and June 30, 1992 in the European Longitudinal Cohort Study of Pregnancy and Childhood-Czech cohort and were surveyed at multiple time points between pregnancy and child age up to 15 years. The Strengths and Difficulties Questionnaire (SDQ) was administered at child age 7, 11, and 15 years to assess child emotional/behavioural difficulties. Perceived gender discrimination was self-reported in mid-pregnancy and child age 7 and 11 years. Multilevel mixed-effects linear regression of SDQ scores were estimated. Mediation was tested using structural equation models.

FINDINGS

Perceived gender discrimination, reported by 11.2% of mothers in mid-pregnancy, was related to increased emotional/behavioural difficulties among children in bivariate analysis (slope = 0.24 [95% confidence interval (CI): 0.15, 0.32], p<0.0001) and in the fully adjusted model (slope = 0.18 [95% CI: 0.09, 0.27], p<0.0001). Increased difficulties were evident among children of mothers with more depressive symptoms (slope = 0.04 [95% CI: 0.03, 0.05], p<0.0001), boys (slope = 0.26 [95% CI: 0.19, 0.34], p<0.0001), first children (slope = 0.16 [95% CI: 0.09, 0.23], p<0.0001), and families under financial hardship (slope = 0.09 [95% CI: 0.04, 0.14], p<0.0001). Effects were attenuated for married mothers (slope-0.12 [95% CI: -0.22, -0.01], p<0.05]. Maternal depressive symptoms and financial hardship mediated about 37% and 13%, respectively, of the total effect of perceived gender discrimination on SDQ scores.

INTERPRETATION

Perceived gender discrimination among child-bearing women in family contexts was associated with more mental health problems among their children and adolescents, extending prior research showing associations with maternal mental health problems. Maternal depressive symptoms and, to a lesser extent, financial hardship both partially mediated the positive relationship between perceived gender discrimination and child emotional/behavioural problems. This should be taken into consideration when measuring the societal burden of gender inequality and gender-based discrimination. Moreover, gender-based discrimination affects more than one gender and more than one generation, extending to boys in the household even moreso than girls, highlighting that gender discrimination is everyone's issue. Further research is required on the intergenerational mechanisms whereby gender discrimination may lead to maternal and child mental health consequences.

Risk factors for community-acquired bacterial infection among young infants in South Asia: a longitudinal cohort study with nested case-control analysis

OBJECTIVE

Risk factors predisposing infants to community-acquired bacterial infections during the first 2 months of life are poorly understood in South Asia. Identifying risk factors for infection could lead to improved preventive measures and antibiotic stewardship.

METHODS

Five sites in Bangladesh, India and Pakistan enrolled mother-child pairs via population-based pregnancy surveillance by community health workers. Medical, sociodemographic and epidemiological risk factor data were collected. Young infants aged 0-59 days with signs of possible serious bacterial infection (pSBI) and age-matched controls provided blood and respiratory specimens that were analysed by blood culture and real-time PCR. These tests were used to build a Bayesian partial latent class model (PLCM) capable of attributing the probable cause of each infant's infection in the ANISA study. The collected risk factors from all mother-child pairs were classified and analysed against the PLCM using bivariate and stepwise logistic multivariable regression modelling to determine risk factors of probable bacterial infection.

RESULTS

Among 63 114 infants born, 14 655 were assessed and 6022 had signs of pSBI; of these, 81% (4859) provided blood samples for culture, 71% (4216) provided blood samples for quantitative PCR (qPCR) and 86% (5209) provided respiratory qPCR samples. Risk factors associated with bacterial-attributed infections included: low (relative risk (RR) 1.73, 95% credible interval (CrI) 1.42 to 2.11) and very low birth weight (RR 5.77, 95% CrI 3.73 to 8.94), male sex (RR 1.27, 95% CrI 1.07 to 1.52), breathing problems at birth (RR 2.50, 95% CrI 1.96 to 3.18), premature rupture of membranes (PROMs) (RR 1.27, 95% CrI 1.03 to 1.58) and being in the lowest three socioeconomic status quintiles (first RR 1.52, 95% CrI 1.07 to 2.16; second RR 1.41, 95% CrI 1.00 to 1.97; third RR 1.42, 95% CrI 1.01 to 1.99).

CONCLUSION

Distinct risk factors: birth weight, male sex, breathing problems at birth and PROM were significantly associated with the development of bacterial sepsis across South Asian community settings, supporting refined clinical discernment and targeted use of antimicrobials.

Paediatric use of emergency medical services in India: A retrospective cohort study of one million children

Background

Millions of children in low- and middle-income countries (LMICs) experience illness or trauma amenable to emergency medical interventions, but local resources are not sufficient to treat them. Emergency medical services (EMS), including ambulance transport, bridge the gap between local services and higher-level hospital care, and data collected by EMS could be used to elucidate patterns of paediatric health care need and use. Here we conducted a retrospective observational study of patterns of paediatric use of EMS services by children who used EMS in India, a leader in maternal and child EMS development, to inform public health needs and system interventions to improve EMS effectiveness.

Methods

We analysed three years (2013-2015) of data from patients <18 years of age from a large prehospital EMS system in India, including 1 101 970 prehospital care records across 11 states and a union territory.

Results

Overall, 38.3% of calls were for girls (n = 422 370), 40.5% were for adolescents (n = 445 753), 65.9% were from rural areas (n = 726 154), and most families were from a socially disadvantaged caste or lower economic status (n = 834 973, 75.8%). The most common chief complaints were fever (n = 247 594, 22.5%), trauma (n = 231 533, 21.0%), and respiratory difficulty (n = 161 120, 14.6%). However, transport patterns, including patient sex and age and type of destination hospital, varied by state, as did data collection.

Conclusions

EMS in India widely transports children with symptoms of the leading causes of child mortality and provides access to higher levels of care for geographically and socioeconomically vulnerable populations, including care for critically ill neonates, mental health and burn care for girls, and trauma care for adolescents. EMS in India is an important mechanism for overcoming transport and cost as barriers to access, and for reducing the urban-rural gap found across causes of child mortality. Further standardisation of data collection will provide the foundation for assessing disparities and identifying targets for quality improvement of paediatric care.

Infectious aetiologies of neonatal illness in south Asia classified using WHO definitions: a primary analysis of the ANISA study

Background

Globally, neonatal mortality accounts for almost half of all deaths in children younger than 5 years. Aetiological agents of neonatal infection are difficult to identify because the clinical signs are non-specific. Using data from the Aetiology of Neonatal Infections in south Asia (ANISA) cohort, we aimed to describe the spectrum of infectious aetiologies of acute neonatal illness categorised post-hoc using the 2015 WHO case definitions of critical illness, clinical severe infection, and fast breathing only.

Methods

Eligible infants were aged 0–59 days with possible serious bacterial infection and healthy infants enrolled in the ANISA study in Bangladesh, India, and Pakistan. We applied a partial latent class Bayesian model to estimate the prevalence of 27 pathogens detectable on PCR, pathogens detected by blood culture only, and illness not attributed to any infectious aetiology. Infants with at least one clinical specimen available were included in the analysis. We assessed the prevalence of these aetiologies according to WHO's case definitions of critically ill, clinical severe infection, and infants with late onset, isolated fast breathing. For the clinical severe definition, we compared the prevalence of signs by bacterial versus viral aetiology.

Findings

There were 934 infants (992 episodes) in the critically ill category, 3769 (4000 episodes) in the clinical severe infection category, and 738 (771 episodes) in the late-onset isolated fast breathing category. We estimated the proportion of illness attributable to bacterial infection was 32·7% in infants in the critically ill group, 15·6% in the clinical severe infection group, and 8·8% among infants with late-onset isolated fast breathing group. An infectious aetiology was not identified in 58–82% of infants in these categories. Among 4000 episodes of clinical severe infection, those with bacterial versus viral attribution had higher proportions of hypothermia, movement only when stimulated, convulsions, and poor feeding.

Interpretation

Our modelled results generally support the revised WHO case definitions, although a revision of the most severe case definition could be considered. Clinical criteria do not clearly differentiate between young infants with and without infectious aetiologies. Our results highlight the need for improved point-of-care diagnostics, and further study into neonatal deaths and episodes with no identified aetiology, to ensure antibiotic stewardship and targeted interventions.

Gender and the impact of COVID-19 on demand for and access to health care: Intersectional analysis of before-and-after data from Kenya, Nigeria, and South Africa

Background

Global health emergencies can impact men and women differently due to gender norms related to health care and social and economic disruptions. We investigated the intersectionality of gender differences of the impact of COVID-19 on health care access with educational and socio-economic factors in Kenya, Nigeria, and South Africa.

Methods

Data were collected by Opinion Research Business International using census data as the sampling frame. We used conditional logistic regression to estimate the change in access to health care after the emergence of the pandemic among men and women, stratified by educational level. We also examined the change in demand for various health care services, stratified by self-reported experiences of financial difficulty due to the pandemic.

Results

Among those reporting a need to seek health care in South Africa, there was a statistically significant decline in the ability to see a health care provider during the pandemic among women, but not among men; this gender gap was more evident in those who did not have post-secondary education (odds ratio (OR) = 0.08, P = 0.041 among women; no change among men) than for those with post-secondary education (OR = 0.20, P = 0.142 among women; OR = 0.50, P = 0.571 among men). South African women financially affected by the pandemic had a significant decline in seeking preventive care during the pandemic (OR = 0.23, P = 0.022). No conclusive effects were noted in Nigeria or Kenya.

Conclusions

In South Africa, the pandemic and its strict control measures have adversely and disproportionately impacted disadvantaged women, which has implications for the nature of the long-term impact as well as mitigation and preparedness plans.

Effect of imbalanced sampling and missing data on associations between gender norms and risk of adolescent HIV

BACKGROUND

Despite strides towards gender equality, inequalities persist or remain unstudied, due potentially to data gaps. Although mapped, the effects of key data gaps remain unknown. This study provides a framework to measure effects of gender- and age-imbalanced and missing covariate data on gender-health research. The framework is demonstrated using a previously studied pathway for effects of pre-marital sex norms among adults on adolescent HIV risk.

METHODS

After identifying gender-age-imbalanced Demographic and Health Survey (DHS) datasets, we resampled responses and restricted covariate data from a relatively complete, balanced dataset derived from the 2007 Zambian DHS to replicate imbalanced gender-age sampling and covariate missingness. Differences in model outcomes due to sampling were measured using tests for interaction. Missing covariate effects were measured by comparing fully-adjusted and reduced model fitness.

FINDINGS

We simulated data from 25 DHS surveys across 20 countries from 2005-2014 on four sex-stratified models for pathways of adult attitude-behaviour discordance regarding pre-marital sex and adolescent risk of HIV. On average, across gender-age-imbalanced surveys, males comprised 29.6% of responses compared to 45.3% in the gender-balanced dataset. Gender-age-imbalanced sampling significantly affected regression coefficients in 40% of model-scenarios (N = 40 of 100) and biased relative-risk estimates away from gender-age-balanced sampling outcomes in 46% (N = 46) of model-scenarios. Model fitness was robust to covariate removal with minor effects on male HIV models. No consistent trends were observed between sampling distribution and risk of biased outcomes.

INTERPRETATION

Gender-health model outcomes may be affected by sampling gender-age-imbalanced data and less-so by missing covariates. Although occasionally attenuated, the effect magnitude of gender-age-imbalanced sampling is variable and may mask true associations, thus misinforming policy dialogue. We recommend future surveys improve balanced gender-age sampling to promote research reliability.

Necessary conditions for sustainable water and sanitation service delivery in schools: A systematic review

Access to water, sanitation, and hygiene (WASH) services confers significant health and economic benefits, especially for children, but only if those services can be delivered on a consistent basis. The challenge of sustainable, school-based WASH service delivery has been widely documented, particularly in resource-constrained contexts. We conducted a systematic review of published research that identifies drivers of, or tests solutions to, this challenge within low- and middle-income countries (PROSPERO 2020 CRD42020199163). Authors in the first group employ cross-sectional research designs and interrogate previously implemented school WASH interventions. Most conclude that dysfunctional accountability and information sharing mechanisms drive school WASH service delivery failures. By contrast, most of the interventions developed and tested experimentally by authors in the second group focus on increasing the financial and material resources available to schools for WASH service delivery. Overall, these authors find negligible impact of such infusions of cash, infrastructure, and supplies across a variety of sustainability outcome metrics. Taken together, the evidence suggests that sustainable service delivery depends on three simultaneously necessary components: resources, information, and accountability. Drawing upon theory and evidence from social psychology, public management, and political science, we identify priority knowledge gaps that can meaningfully improve the design of effective interventions. We also highlight the importance of both interdisciplinary collaboration and local expertise in designing WASH programming that aligns with sociocultural and institutional norms, and is thus more likely to generate sustainable impact.

World Health Organization and knowledge translation in maternal, newborn, child and adolescent health and nutrition

The World Health Organization (WHO) has a mandate to promote maternal and child health and welfare through support to governments in the form of technical assistance, standards, epidemiological and statistical services, promoting teaching and training of healthcare professionals and providing direct aid in emergencies. The Strategic and Technical Advisory Group of Experts (STAGE) for maternal, newborn, child and adolescent health and nutrition (MNCAHN) was established in 2020 to advise the Director-General of WHO on issues relating to MNCAHN. STAGE comprises individuals from multiple low-income and middle-income and high-income countries, has representatives from many professional disciplines and with diverse experience and interests.Progress in MNCAHN requires improvements in quality of services, equity of access and the evolution of services as technical guidance, community needs and epidemiology changes. Knowledge translation of WHO guidance and other guidelines is an important part of this. Countries need effective and responsive structures for adaptation and implementation of evidence-based interventions, strategies to improve guideline uptake, education and training and mechanisms to monitor quality and safety. This paper summarises STAGE's recommendations on how to improve knowledge translation in MNCAHN. They include support for national and regional technical advisory groups and subnational committees that coordinate maternal and child health; support for national plans for MNCAHN and their implementation and monitoring; the production of a small number of consolidated MNCAHN guidelines to promote integrated and holistic care; education and quality improvement strategies to support guidelines uptake; monitoring of gaps in knowledge translation and operational research in MNCAHN.

Quantitative decision making for investment in global health intervention trials: Case study of the NEWBORN study on emollient therapy in preterm infants in Kenya

Background

Partners from an NGO, academia, industry and government applied a tool originating in the private sector – Quantitative Decision Making (QDM) – to rigorously assess whether to invest in testing a global health intervention. The proposed NEWBORN study was designed to assess whether topical emollient therapy with sunflower seed oil in infants with very low birthweight <1500 g in Kenya would result in a significant reduction in neonatal mortality compared to standard of care.

Methods

The QDM process consisted of prior elicitation, modelling of prior distributions, and simulations to assess Probability of Success (PoS) via assurance calculations. Expert opinion was elicited on the probability that emollient therapy with sunflower seed oil will have any measurable benefit on neonatal mortality based on available evidence. The distribution of effect sizes was modelled and trial data simulated using Statistical Analysis System to obtain the overall assurance which represents the PoS for the planned study. A decision-making framework was then applied to characterise the ability of the study to meet pre-selected decision-making endpoints.

Results

There was a 47% chance of a positive outcome (defined as a significant relative reduction in mortality of ≥15%), a 45% chance of a negative outcome (defined as a significant relative reduction in mortality <10%), and an 8% chance of ending in the consider zone (ie, a mortality reduction of 10 to <15%) for infants <1500 g.

Conclusions

QDM is a novel tool from industry which has utility for prioritisation of investments in global health, complementing existing tools [eg, Child Health and Nutrition Research Initiative]. Results from application of QDM to the NEWBORN study suggests that it has a high probability of producing clear results. Findings encourage future formation of public-private partnerships for health.

Gender Norms and Gender Equality in Full-Time Employment and Health: A 97-Country Analysis of the World Values Survey

Background

Almost nowhere in the world do women participate as much as men in the labor force. Despite differences in countries’ economic, social and cultural contexts, gender norms—unwritten rules of acceptable actions for men and women—have been found to affect women’s labor participation across contexts. Gender norms include those regulating who takes care of children, who is expected to earn more, and in which sectors men and women should work. Importantly, norms affect access to labor markets at times of scarcity: when there’s only work for one, gender norms can dictate whether a woman or man gets the job. Advocates of equal labor force participation point to evidence that employment can contribute to people’s health and well-being; yet the evidence is mixed and contradictory, and mostly comes from high-income countries. In restrictive normative contexts in which women are assigned the role of family caretaker, full time employment (FTE) might be particularly burdensome. At the same time, the literature lacks a cross-country analysis of how gender norms affect women’s FTE and their health when employed full time, despite qualitative research providing clear evidence of the influence of gender norms on labor participation.

Aims

In this paper we examine: (1) how gender norms affect women’s access to FTE across 97 countries; (2) associations between FTE and women’s self-reported health self-rated (SRH) across different normative contexts (i.e., countries where it is common vs. uncommon for women to stay home); and (3) how women’s FTE and gender norms changed over time in four countries.

Data

We used time-series data from the World Values Survey and European Values Survey conducted in over 100 countries between 1981 and 2014. Both surveys attempt to capture norms, beliefs and values in addition to sociodemographic information among a nationally representative adult population in each country. The sample for the cross-sectional analyses (aims 1 and 2) included 97 countries and 131,132 respondents. The sample for aim 3 included data from Argentina, Egypt, Finland and Japan.

Variables

Our outcome of interest was pro-equality norms in the context of access to the labor market for women. Respondents were asked “if jobs are scarce, men should have more right to a job than women do?”. Response options included no, neither or yes. We created a binary variable to represent pro-equality norms. We included employment status and SRH as exposures of interest.

Analysis

We used individual-level data to generate on-average and sex-stratified estimates of the outcome and exposures for each country, at each time point. We estimated the percentage of all respondents, of women, and of men who held pro-equality norms (believe that men should not have more right to a job than women), the percentage who were employed full time, and the average level of SRH. To measure gender inequality in FTE, we also estimated the absolute difference in FTE between women and men for each country at each time point. First, we conducted descriptive, cross-sectional ecological analyses using one survey per country from wave 5 or 6 (whichever was most recent) to examine associations between pro-equality norms and employment status as a proxy for associations between norms and the context of employment in each country. We also examined associations between pro-equality norms and SRH. We then specified adjusted logistic regression models with controls for age, sex and education to examine associations between pro-equality norms and employment status. To examine if the relationship between FTE and SRH varied by normative context, we grouped countries in quartiles of pro-equality norms. Finally, we conducted descriptive ecological analyses of the relationship between pro-equality norms and employment status over time in four countries.

Results

Objective 1: Gender norms intersect with socio-cultural contexts in determining women’s FTE. While in some countries gender norms aligned positively with women’s access to employment (i.e., more equal norms matched more equality in FTE), in Eastern Europe and South America we observed a mismatch. In Eastern Europe we found strong norms against equal access but small sex differences in FTE. In South America, we observed a stark difference in FTE favoring men, despite positive gender norms promoting women’s paid employment. Objective 2: We found the association between SRH and FTE to vary across normative contexts. For instance, while in Scandinavian countries it was protective to be a woman in FTE and harmful not to work full-time, we found the opposite effect in Middle Eastern countries. Objective 3: We found a general tendency to move toward greater equality in norms and FTE over time everywhere in the world. However, political and economic events can generate variations over time and setbacks in progress toward equality.We specifically looked at 4 countries: Argentina, Egypt, Finland and Japan and assessed the effects of economic, political and national legislative changes on FTE over time.

Implications

This paper contributes to the conversation on tensions between universal justice and contextual factors affecting one’s health. To achieve purposeful and global universal health and justice, policy makers and global health practitioners must design effective, context-relevant interventions that are deeply and transparently informed by the values they embody. As we strive to achieve global gender equality, its meanings and purposes will vary across contexts in ways that demand people-led conversations and interventions.

Stress and Its Consequences-Biological Strain

Understanding the role of stress in pregnancy and its consequences is important, particularly given documented associations between maternal stress and preterm birth and other pathological outcomes. Physical and psychological stressors can elicit the same biological responses, known as biological strain. Chronic stressors, like poverty and racism (race-based discriminatory treatment), may create a legacy or trajectory of biological strain that no amount of coping can relieve in the absence of larger-scale socio-behavioral or societal changes. An integrative approach that takes into consideration simultaneously social and biological determinants of stress may provide the best insights into the risk of preterm birth. The most successful computational approaches and the most predictive machine-learning models are likely to be those that combine information about the stressors and the biological strain (for example, as measured by different omics) experienced during pregnancy.

"So Why Should I Call Them?": Survivor Support Service Characteristics as Drivers of Help-Seeking in India

Women in South Asia face the highest lifetime prevalence of intimate partner violence in the world, which is just one form of violence against women (VAW). In India, few women seek help after experiencing violence, particularly from formal resources, such as physicians or the police. While many studies have investigated the impact of survivor characteristics and patterns of violence on help-seeking behaviors, there is scant research on support service characteristics and their impact on help-seeking. The introduction of a novel crisis helpline in Gujarat, India provided an opportunity to better understand how successful help-seeking can be driven by the perceived and experienced characteristics of the helpline. We conducted in-depth interviews with helpline users to identify factors and pathways that promoted or discouraged help-seeking in general, help-seeking from a formal source, and help-seeking from this particular helpline. We analyzed 32 interviews of women who used the helpline. Participants were from eight districts across the state, representing a diverse range of sociodemographic backgrounds. After conducting a thematic analysis, we found that action-oriented service, timeliness, and women-focused staff influenced (positively and negatively) participants' feelings of safety, empowerment, and trust in the helpline, which ultimately impacted their decision to seek help from the helpline or even to seek help at all. This study illuminates how service characteristics, in and of themselves, can influence the likelihood that survivors will seek help, emphasizing the need for survivors to have a voice in the growth and refinement of VAW support services. Consequently, these areas must be a focus of future research and initiatives to improve help-seeking by VAW survivors.

Evaluation of community health worker's performance at home-based newborn assessment supported by mHealth in rural Bangladesh

BACKGROUND

In low to middle-income countries where home births are common and neonatal postnatal care is limited, community health worker (CHW) home visits can extend the capability of health systems to reach vulnerable newborns in the postnatal period. CHW assessment of newborn danger signs supported by mHealth have the potential to improve the quality of danger sign assessments and reduce CHW training requirements. We aim to estimate the validity (sensitivity, specificity, positive and negative predictive value) of CHW assessment of newborn infants aided by mHealth compared to physician assessment.

METHODS

In this prospective study, ten CHWs received five days of theoretical and hands-on training on the physical assessment of newborns including ten danger signs. CHWs assessed 273 newborn infants for danger signs within 48 h of birth and then consecutively for three days. A physician repeated 20% (n = 148) of the assessments conducted by CHWs. Both CHWs and the physician evaluated newborns for ten danger signs and decided on referral. We used the physician's danger sign identification and referral decision as the gold standard to validate CHWs' identification of danger signs and referral decisions.

RESULTS

The referrals made by the CHWs had high sensitivity (93.3%), specificity (96.2%), and almost perfect agreement (K = 0.80) with the referrals made by the physician. CHW identification of all the danger signs except hypothermia showed moderate to high sensitivity (66.7-100%) compared to physician assessments. All the danger signs assessments except hypothermia showed moderate to high positive predictive value (PPV) (50-100%) and excellent negative predictive value (NPV) (99-100%). Specificity was high (99-100%) for all ten danger signs.

CONCLUSION

CHW's identification of neonatal danger signs aided by mHealth showed moderate to high validity in comparison to physician assessments. mHealth platforms may reduce CHW training requirements and while maintaining quality CHW physical assessment performance extending the ability of health systems to provide neonatal postnatal care in low-resource communities.
