OBJECTIVES

Adiposity rebound (AR), the childhood period at which body mass index (BMI) rises from its lowest point, is linked to increased risk of later obesity. The study aims to determine the average age at AR, describe baseline characteristics and analyze the correlation between these characteristics and timing of AR in a population of Filipino pediatric outpatients.

Seven subjects born between 2016 and 2019 from a University Hospital Outpatient Department participated in this cross-sectional analytic study. Childhood anthropometrics were retrospectively collected to determine the age at AR by plot visual inspection. Sex, birth weight and gestational age were obtained from hospital records; breastfeeding duration, maternal BMI, parental obesity, maternal age, maternal smoking, education, parity and family income were gathered through a questionnaire completed by mothers or guardians. Associations were assessed using bootstrap univariate linear regression.

The mean age at AR was 3.2 years (SD = 1.2). Vaginal delivery was significantly associated with later age at AR compared to cesarean section (p = 0.035). Socioeconomic status at ages 2 to 5 showed positive association with delayed AR. Higher monthly family income (≥₱19,000) at ages 2 to 5 years was significantly associated with delayed age at AR. Other baseline childhood and parental factors showed no significant correlation with age at AR.

These results highlight the complex and context-dependent nature of AR, emphasizing the need for further studies to better understand and mitigate early obesity risk in Filipino children.

INTRODUCTION: Preterm birth (PTB) remains a leading cause of perinatal morbidity and mortality worldwide. Understanding Singapore's PTB trends and associated risk factors can inform effective strategies for screening and intervention. This study analyses PTB trends in Singapore from 2017 to 2023, identifies risk factors in this multi-ethnic population and evaluates a predictive model for PTB. METHOD: A retrospective analysis of all PTBs between 22+0 and 36+6 weeks of gestation, from 1 January 2017 to 31 December 2023, was performed by extracting maternal and neonatal data from electronic medical records. These PTBs were taken from the registry of births for Singapore and SingHealth cluster data. Cochran- Armitage trend test and multinomial logistic regression were used. An extreme gradient boosting (XGBoost) model was developed to test and predict the risk of PTB. RESULTS: The PTB rate in Singapore did not show a significant change. However, there was modest downward trend in the SingHealth population from 11.3% to 10.2%, mainly in late spontaneous PTBs (sPTBs). sPTBs accounted for ∼60% of PTBs. Risk factors for very/extreme sPTB included Chinese ethnicity, age ≥35 years, body mass index (BMI) ≥23 kg/m², being unmarried, primiparity, twin pregnancy and maternal blood group AB. The XGBoost model achieved an area under the receiver operating characteristic curve of 0.75, indicating moderate ability to predict PTB. CONCLUSION The overall PTB rate in Singapore has not improved. This study underscores the importance of local factors, particularly advanced maternal age, BMI, primiparity, unmarried, Chinese ethnicity and maternal blood group AB influencing PTB risk. Artificial intelligence methods show promise in improving PTB risk stratification, ultimately supporting personalised care and intervention.

Severe combined immunodeficiency (SCID) represents a group of genetically heterogeneous disorders characterized by mutations that lead to profound defects in both humoral and cellular immunity. Transplacental maternal engraftment (TME) is a frequently observed complication in SCID. While most cases of SCID with TME exhibit no substantial impact on disease progression, a subset of patients may encounter diagnostic delays or therapeutic challenges due to TME interference. Furthermore, TME may predispose these individuals to graft-versus-host disease (GVHD) prior to hematopoietic stem cell transplantation, thereby increasing diagnostic complexity and treatment risks. This review systematically examines the etiology and clinical manifestations of SCID associated with TME, analyzes its implications for disease management, and evaluates current detection methodologies. The synthesized evidence provides a theoretical foundation for future research and offers potential insights into the clinical diagnosis and management of SCID associated with TME.

BACKGROUND: Dental caries is a chronic childhood disease and one of the most prevalent public health problems worldwide. Lead is a heavy metal that is taken up by the teeth and bones. However, the association between lead exposure during pregnancy, when the tooth germs are formed, and the prevalence of dental caries in the primary dentition remains unclear. This study aimed to examine the association between maternal blood lead levels and the prevalence of dental caries in the primary dentition of children. METHODS: This cross-sectional study was conducted as an Adjunct Study to the Japan Environment and Children's Study (JECS), which is an ongoing nationwide birth-cohort study. Among children participating in the JECS at the University of Occupational and Environmental Health Sub-Regional Center, those aged 7-8 years underwent oral examination and questionnaire administration. The dft (i.e., sum of the number of decayed and filled primary teeth) was then determined. The dft numerically expresses the dental caries prevalence in the primary dentition (larger value indicates more prevalent dental caries). Poisson regression analyses with robust standard errors were performed to evaluate the association between maternal blood lead levels during pregnancy, measured using frozen samples, and the dft. RESULTS: The study included 139 children, of whom 54.7% were girls, and 89.2% were 7 years old. The median maternal blood lead level was 6.1 ng/g (25-75 percentile, 5.0-7.3). The median dft was 0 (25-75 percentile, 0-4). After adjusting for covariates including age, sex, and oral health status and behavior, maternal blood lead levels were significantly associated with increased dft (prevalence ratio, 1.6; 95% confidence interval, 1.3-1.8; per one standard deviation increase in natural log-transformed maternal blood lead levels). CONCLUSIONS This study found an association between maternal blood lead levels and the prevalence of dental caries in the primary dentition of children aged 7-8 years. Maternal exposure to lead during mid- to late-term pregnancy may affect the caries susceptibility of children after birth.

BACKGROUND

This study explores the professional functions and experiences of male midwives in the Province of Aurora, highlighting their roles, challenges, and contributions to maternal and child healthcare in a traditionally female-dominated profession.

This study aims to investigate the professional functions and lived experiences of male midwives in the Province of Aurora.

This research employed a qualitative ethnographic design using semi-structured interviews to collect data. Participants were six male midwives practicing in Aurora. Data collection was conducted via mobile phone interviews from August to September 2024. A purposive sampling technique was utilized to select participants. The study adhered to ethical guidelines, receiving approval from the University of Northern Philippines Ethics Review Committee Code: 2024-251, and informed consent was obtained from all participants. Data were analyzed using qualitative content analysis. Qualitative inductive content analysis as described by Padgett was utilized to allow for data-driven analysis without pre-defined themes, making it suitable for exploring the diverse experiences of male midwives.

Analysis revealed six key themes: Diverse professional functions, gender bias and stereotyping, patient reluctance and shyness, cultural influences, experiences of discrimination and prejudice, and daily challenges and rewards in practice. The findings underscore the commitment of male midwives to providing quality care despite societal and professional barriers. Under the Functions theme, male midwives described their roles as not only caregivers but also as advocates for gender inclusivity in midwifery. In terms of experiences, some reported feelings of isolation and the need to prove their competence in a field dominated by women. However, they also shared empowering stories of camaraderie with female colleagues and the satisfaction derived from breaking down gender barriers.

Male midwives play a vital role in maternal and newborn healthcare, navigating challenges such as gender bias and patient hesitancy. Strengthening administrative support, promoting inclusivity, and updating policies can enhance their professional integration. Advocacy efforts from professional organizations are necessary to address workplace challenges and recognize their contributions to healthcare.

BACKGROUND

Antenatal care (ANC) is a key maternal health intervention designed to prevent poor pregnancy outcomes, while pregnancy tracking by community healthcare workers (CHWs) serves as an important strategy to monitor its effective implementation and utilization. In Mati City, Davao Oriental, Philippines, a consistent decline in ANC quality and a rise in maternal and infant mortality have been observed, which may be linked to gaps in the implementation of maternal healthcare programs.

To address this concern, the study aims to analyze the strategies and challenges faced by CHWs in pregnancy tracking, assess the perceptions of health officials regarding these gaps, and recommend governance strategies to enhance the overall quality of ANC services.

A qualitative research design was employed, using purposive sampling to select Barangay Health Workers, midwives, and nurses for the focus group discussions, while the City Mayor, City Health Officer, and City Councilor on Health participated as key informants. Thematic analysis was conducted on manually transcribed data while adhering to strict ethical considerations.

Findings revealed that proper implementation and monitoring of maternal healthcare services are crucial for effective pregnancy tracking. CHWs play a significant role in health service delivery; however, gaps such as weak health promotion efforts adversely affect community engagement, health-seeking behavior, and sociocultural dynamics, highlighting the need for stronger policy enforcement and sustained local government support. Systemic and logistical challenges must also be addressed to improve service delivery. Effective maternal healthcare requires robust policy implementation and close collaboration among local government units. A sustainable maternal health system further depends on depoliticized legislative processes, improved health financing, and continuous investments in primary healthcare and infrastructure. Based on these findings, the study developed the Strengthen, Empower, Engage, and Key Policy Reforms Framework – an innovative governance approach aimed at reducing maternal healthcare disparities through multisectoral collaboration, depoliticized legislative action, and evidence-based maternal health interventions.

Adopting the SEEK framework may enable local governments to ensure equitable access to high-quality ANC and ultimately improve maternal and infant health outcomes.

BACKGROUND

Facility-based delivery (FBD) is a key intervention for reducing maternal and neonatal mortality. Despite policies discouraging home births, 11% of all deliveries in the Philippines occur outside health facilities. The health belief model (HBM) suggests that healthcare-seeking is influenced by perceived risks, benefits and barriers, and cues to action.

To examine how HBM indicators are associated with the likelihood of FBD and to assess the added value of increasing antenatal care (ANC) contacts from four to eight in line with recommendations by the World Health Organization.

Using data from the 2017 National Demographic and Health Survey, we ran logistic regression models on a sample of 6551 women with a recent live birth to estimate how HBM indicators were linked to the probability of FBD.

FBD was more likely among women with higher pregnancy risks (first birth and delivery complications) and those facing fewer barriers to health care (higher education, wealthier households, public health insurance coverage, urban residence, and not Muslim). Being Muslim had the largest negative impact on the probability of FBD (-19% points). Having at least eight (instead of four) ANC contacts increased the probability of FBD by 6% points.

FBD in the Philippines is shaped by perceived risks, socioeconomic and cultural barriers, and ANC contacts as cues to action. Increasing antenatal contacts was associated with a higher likelihood of FBD. Policies should therefore prioritize expanding affordable, accessible, and culturally responsive maternal healthcare services to reduce inequalities, rather than penalizing home births.

BACKGROUND

Advanced maternal age is associated with diminished IVF outcomes, including reduced live birthrates and increased miscarriage risk.

To determine clinical profiles and reproductive outcomes of Filipino women of advanced age who underwent autologous IVF at the Center for Advanced Reproductive Medicine and Infertility at St. Luke’s Medical Center Global City from January 1 , 2018 to December 31, 2024.

This retrospective cohort study analyzed 667 Filipino women aged 38 years and above who underwent autologous IVF/ICSI-ET from 2018 to 2024. Clinical profiles and reproductive outcomes were compared across age groups and embryo transfer types.

Results showed significant age-related decline identified in reproductive outcomes such as clinical pregnancy and live birth rates, coupled with elevated miscarriage rates in older women. Frozen embryo transfers demonstrated superior outcomes versus fresh transfers. While PGT-A improved embryo selection, it did not fully mitigate age-related declines.

These findings underscore the persistent negative impact of advanced maternal age on IVF success, highlighting the importance of early fertility intervention, individualized treatment strategies, and context-specific research in resource-constrained settings.

OBJECTIVES: Exposure to rare earth elements (REEs) has been linked to various systemic diseases, but their impact on the offspring blood-brain barrier (BBB) via the gut-brain axis remains unclear. This study aims to investigate the effects of maternal exposure to neodymium oxide (Nd₂O₃) on the BBB integrity of offspring rats, and to evaluate the potential protective role of bifidobacterium tetrad viable tablets (BTVT) against Nd₂O₃-induced intestinal and BBB damage. METHODS: Healthy adult SD rats were mated at a 1:1 male-to-female ratio, with the day of vaginal plug detection marked as gestational day 0. A total of 60 pregnant rats were randomly assigned to the following groups: Control, 50 mg/(kg·d) Nd₂O₃, 100 mg/(kg·d) Nd₂O₃, 200 mg/(kg·d) Nd₂O₃, and 200 mg/(kg·d) Nd₂O₃ + BTVT group. Treatments were administered by daily oral gavage throughout pregnancy and lactation. On postnatal day 21 (weaning), offspring feces, brain, and colon tissues were collected. Hematoxylin and eosin (HE) staining was used to assess structural changes in brain and intestinal tissues. Short-chain fatty acids (SCFAs) in feces were quantified by gas chromatography-mass spectrometry (GC-MS). Evans Blue (EB) dye extravasation assessed BBB permeability. Gene and protein expression levels of tight junction proteins occludin and zonula occludens-1 (ZO-1) were measured by reverse transcription PCR (RT-PCR) and Western blotting (WB), respectively. Neodymium levels in brain tissue were determined via inductively coupled plasma mass spectrometry (ICP-MS). RESULTS: HE staining revealed that maternal Nd₂O₃ exposure caused mucosal edema, increased submucosal spacing, and lymphocyte infiltration in offspring colon, as well as neuronal degeneration and vacuolization in brain tissue. BTVT intervention alleviated these changes. GC-MS analysis showed that levels of acetic acid, propionic acid, butyric acid, and isobutyric acid significantly decreased, while valeric acid and isovaleric acid increased in offspring of Nd₂O₃-exposed mothers (P<0.05). BTVT significantly restored levels of acetic, propionic, and isobutyric acids and reduced valeric acid content (P<0.05). EB permeability was significantly elevated in Nd₂O₃-exposed offspring brains (P<0.05), but reduced with BTVT treatment (P<0.05). RT-PCR and WB showed downregulation of occludin and ZO-1 expression following Nd₂O₃ exposure (P<0.05), which was reversed by BTVT (P<0.05). ICP-MS results indicated significantly increased brain neodymium levels in offspring from all Nd₂O₃-exposed groups (P<0.05), while BTVT significantly reduced neodymium accumulation compared to the 200 mg/(kg·d) Nd₂O₃ group (P<0.05). CONCLUSIONS Maternal exposure to Nd₂O₃ during pregnancy and lactation disrupts intestinal health and BBB integrity in offspring, elevates brain neodymium accumulation, and induces neuronal degeneration. BTVT effectively mitigates Nd₂O₃-induced intestinal and BBB damage in offspring, potentially through modulation of the gut-brain axis.
