RESUMO

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. TRIAL REGISTRATION: Clinicaltrials.gov NCT05461404.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.
