BackgroundNeural tube defects (NTDs) are severe congenital anomalies resulting from the incomplete closure of the embryonic neural tube, affecting around 300,000 newborns globally each year and leading to significant mortality and disability. While high-income countries have seen a reduction in NTD prevalence, developing nations like Ethiopia continue to face high rates. Families impacted by NTDs often endure emotional challenges, including grief, anxiety, and social isolation. This study aims to investigate the birth prevalence of NTDs and the associated parental stress, emphasizing the wider effects on families.
MethodologyAn institution-based cross-sectional study was conducted in Dessie and Deber Berhan comprehensive specialized hospitals from July 24, 2023, to July 24, 2024, to evaluate the birth prevalence of NTDs and the associated parental stress among parents of children aged 1 month to 12 years diagnosed with NTDs. A total of 308 parent-child pairs participated in the study. Data were gathered using a pretested questionnaire and an 18-item Parenting Stress Scale. Statistical analysis was performed using Stata version 17, where linear regression was utilized to identify significant predictors after verifying the necessary assumptions. The findings were presented in multiple formats for clarity and comprehensibility.
ResultsThe overall birth prevalence of neural tube defects was found to be 0.0052 (95% CI: 0.0038, 0.0067), which translates to 52 cases per 10,000 deliveries. Key factors associated with increased parental stress included being a mother (β = 2.51), older parental age (β = 0.18), the child’s age (β = 0.81), a prior history of having children with NTDs (β = 7.88), and the presence of a ventriculoperitoneal shunt in the child (β = 4.66).
ConclusionThe findings of this study indicate that the birth prevalence of NTDs is becoming a significant public health concern. Additionally, several factors contributing to increased parental stress were identified, including older parental age, the child’s age, a previous history of NTDs in siblings, and the presence of a ventriculoperitoneal shunt. These results highlight the urgent need for targeted support and resources for affected families to help mitigate the psychological impact associated with these conditions.

Conventional culture media such as de Man, Rogosa and Sharpe are essential for the growth of lactic acid bacteria and the production of metabolites used in the food and pharmaceutical industries. However, their high cost limits their application, particularly in low and middle-income countries. This study aimed to develop a cost-effective and efficient culture medium based on agro-industrial and environmental by-products, pineapple peels, sugarcane molasses, and black soldier fly larvae cake. After physico-chemical analysis of the by-products, excluding sugarcane molasses, a statistical mixture design was used to determine the optimal proportions for supporting lactic acid bacteria growth and bacteriocin production. Growth and metabolite production were monitored via plate count and agar well diffusion assays respectively. The strains tested belonged to the genera Lactobacillus, Bifidobacterium, Streptococcus, Lactococcus, and Bacillus as an out taxa group. The larvae cake showed high protein (48.47 ± 0.14%) and amino acid (17 types) content, while pineapple peels and molasses were rich in carbohydrates (89.52 ± 0.16% and 86.86 ± 0.07%). Based on regression models, the compromise formulation was defined as 55.15% larvae cake hydrolysate, 19.85% pineapple peel hydrolysate, and 25.00% sugarcane molasses. This medium highly supported lactic acid bacteria growth (9.43–9.86 log CFU/mL) compared to MRS and M17 (9.20–9.69 log CFU/mL), with Lactobacillus strains performing better. It also supported bacteriocin activity (11.0–14.5 mm inhibition zones), higher or similar to MRS and M17, with Lactococcus lactis subsp. lactis MA2 exhibiting the strongest effect. These results highlight the potential of this formulation as a sustainable, low-cost alternative for microbiology and biotechnology, particularly in resource-limited settings. The determination of its formula will allow its manufacture once the proximate compositions of the ingredients are known, regardless their origin. Future investigations will focus on optimisation of culture conditions, powder form formulation, and cost evaluation.by Bing Wu, Pengli Wei, Jiaxiang Deng, Yuanyuan Rui
BackgroundThe atherogenic index of plasma (AIP) is a recognized marker of atherosclerosis and cardiovascular disease (CVD). However, the association between AIP and the risk of acute kidney injury (AKI) in critically ill patients with sepsis has not yet been investigated.
MethodsThe data used in this study were derived from the Medical Information Mart for Intensive Care (MIMIC-IV) database. The clinical outcome was the occurrence of AKI. Logistic regression was used to assess the association between AIP and the risk of AKI in sepsis patients. Restricted cubic spline (RCS) analysis was applied to explore potential non-linear relationships. Threshold analysis confirmed a turning point at this value. Subgroup analyses evaluated the consistency of the association across different strata. Mediation analysis was performed to explore potential intermediate variables.
ResultsAmong 1,874 sepsis patients, higher AIP levels were associated with increased AKI incidence. Logistic regression showed a significant association between AIP and AKI in unadjusted and partially adjusted models, but the association was no longer significant after full adjustment. RCS analysis revealed a nonlinear relationship with a peak AKI risk at AIP = 1.333. Threshold analysis confirmed a turning point at this value. Subgroup analyses showed consistent associations, while nonlinear effects were more evident in specific groups. Mediation analysis suggested that SOFA score, creatinine, WBC count, and respiratory rate partially mediated the AIP-AKI relationship.
ConclusionAIP was nonlinearly associated with AKI in sepsis, with a clear threshold effect. This relationship was partially mediated by SOFA score, creatinine, WBC, and respiratory rate. AIP may serve as a useful marker for AKI risk assessment.

BackgroundPreeclampsia (PE) is a life-threatening pregnancy disorder lacking reliable early biomarkers. While apoptosis is implicated in PE pathogenesis, the role of regulated necrotic cell death (necroptosis) remains poorly understood. This study aimed to identify necroptosis-related biomarkers, and further provide the potential natural compounds for PE with virtual screening.
MethodsPublic datasets (GSE66273 for training set; GSE44711 for validation set; GSE173193 for single-cell RNA-seq) were analyzed. Differentially expressed genes (DEGs) were screened using limma (|log2FC| > 1, P Results
The analysis of the GSE66273 dataset identified 367 DEGs. Intersection with necroptosis-related genes revealed 3 necroptosis-related DEGs (NRDEGs), from which BIRC3 was prioritized as hub gene through PPI networks and machine learning (random forest). BIRC3 demonstrated significant diagnostic potential in the discovery cohort (AUC = 0.933) and maintained strong performance in the independent validation cohort (AUC = 0.844). Single-cell analysis revealed BIRC3 was predominantly expressed in immune lineages, particularly NK/T cells, with a significantly higher proportion of BIRC3-positive cells in PE placentas (p Conclusion
This comprehensive analysis implicates necroptosis in PE pathogenesis. BIRC3 is proposed as a novel diagnostic biomarker and therapeutic target, with multi-omics validation underscoring its role in immune dysregulation and placental dysfunction.

BackgroundAlzheimer’s disease and other dementias (ADRD) are significant global health concerns, with rising incidence rates and substantial social and economic implications due to population aging.
MethodsWe investigated trends in ADRD incidence from 1992 to 2021 across age, sex, and socio-demographic index (SDI) regions, utilizing data from the Global Burden of Disease (GBD) 2021 platform. An age-period-cohort (APC) model was employed to analyze the effects of age, period, and birth cohort on ADRD incidence, and a Bayesian age-period-cohort (BAPC) model was used to predict future trends.
ResultsGlobally, the age-standardized incidence rates (ASIR) remained relatively steady. However, the total number of ADRD cases witnessed a remarkable 141.25% increase, with 9,837,056 cases (95% UI: 8,620,519–11,163,700) in 2021. High SDI regions exhibited higher ASIR, whereas high-middle SDI regions showed the greatest growth, particularly among females. The net drift of ADRD incidence ranged from 0.43% per year in China to −0.68% per year in Denmark. Age effect was consistent across SDI regions, increasing exponentially with age. The 60–64 age group experienced the fastest annual incidence growth. High-middle SDI regions faced unfavorable period and cohort effects.
ConclusionAlthough progress in ADRD globally, significant regional and sex disparities persist. Strengthened surveillance and management of adults over 60 are urgently needed. Targeted public health policies and interventions are essential to address the escalating global dementia burden.

BackgroundFaster time to reperfusion can be achieved by minimizing various patient and system-level delays that contribute to total ischemic time. Procedural delays within the catheterization laboratory represent a non-negligible and modifiable component in the chain of reperfusion, but remain unquantified by conventional metrics such as door-to-ballon (D2B) time. Universal catheter approaches have rapidly gained traction as an alternative to the traditional two catheter approach for transradial coronary interventions. However, their utility for both diagnostic angiography and subsequent angioplasty is limited, and the impact of this strategy on reperfusion outcomes has remained unexplored. We utilized a procedural metric termed fluoroscopy-to-device (FluTD) time to quantify the efficiency of a single catheter strategy, and assessed its impact on epicardial and myocardial perfusion.
Methods and resultsIn this retrospective study, consecutive STEMI patients undergoing transradial primary PCI (pPCI) at a tertiary care center in India between May 2022 to October 2024 were analyzed. Patients were divided into two groups: 51 underwent PCI using a single universal guiding catheter (UGC), and 51 underwent the conventional two-catheter (CTC) approach. The primary outcome of the study was a comparison of the FluTD time between the two procedural strategies. Secondary outcomes included myocardial blush grade (MBG), Thrombolysis in Myocardial Infarction (TIMI) flow grade, total fluoroscopy time, radiation dose, device safety and efficacy, and procedural success.The median FluTD time was significantly shorter in the UGC compared to the CTC group (3 minutes [IQR 3–4] vs. 10 minutes [IQR 8–17], p Conclusion
A single catheter strategy for both angiography and pPCI in STEMI patients was associated with a significant reduction in FluTD time and improved microvascular perfusion, without compromising device safety or efficacy. In low- and middle-income countries (LMICs), where intra- and extra-procedural delays are often more pronounced, inclusion of the single catheter strategy can optimize catheterization workflows and yield substantial cost-savings.

Pregnancy and childbirth involve profound biomechanical transformations, adaptations, and functional demands on the maternal body. Although biomechanical complications have been identified as a major contributor to maternal morbidity and mortality, this remains one of the most under-researched areas in perinatal health. This systematic scoping review aimed to map and synthesise existing literature on the biomechanics of pregnancy and labour. Following Arksey and O’Malley’s framework and PRISMA-ScR guidance, comprehensive searches of MEDLINE, EMBASE, and MIDIRS were conducted up to May 2025. Eligible sources were peer-reviewed empirical studies assessing musculoskeletal, kinematic, kinetic, postural, or dynamic parameters in pregnant or labouring women. Titles, abstracts, and full texts were screened against predefined eligibility criteria. Data were charted using a structured extraction form and synthesised narratively across key biomechanical themes. Eighty-seven studies were included, all of which focused on pregnancy. No studies conducted during labour were identified. Most were observational with small sample sizes and limited diversity. Ethnicity was reported in only one study. Four key themes emerged: (1) Posture and spinal curvature, (2) Gait and locomotor analysis, (3) Functional tasks and interventions, and (4) Balance and stability. Findings showed high individual variability and no consistent biomechanical pattern across pregnancy. Real-world, neuromuscular, and labour-related biomechanics remain largely unexplored. This review underscores a critical gap in perinatal research: while biomechanical adaptations during pregnancy have been increasingly studied, labour remains entirely unexamined from a biomechanical perspective. Current evidence is fragmented, methodologically narrow, and lacks diversity, offering limited clinical relevance. We are effectively operating in a biomechanical vacuum, without empirical data to guide safer, more efficient, and personalised birth practices. Existing clinical approaches rely heavily on tradition, anecdotal experience, and untested theoretical assumptions. Addressing this evidence void, particularly in labour biomechanics and ethnic representation, is essential to improve perinatal outcomes and support equity in maternal care.by Yizhuo Gong, Xinmeng Wang, Mingkun Yu, Peipei Zu
PurposeTo precisely evaluate the independent influence of two different optical zone (OZ) sizes (6.3 mm vs. 6.5 mm) on corneal biomechanical properties within 6 months after Small Incision Lenticule Extraction (SMILE) using multivariable-adjusted statistical models.
MethodsThis retrospective study included myopic patients who underwent SMILE between 2022 and 2024. Patients were grouped into two groups based on the planned OZ: Group A (6.3 mm, 44 eyes) and Group B (6.5 mm, 54 eyes). Corneal biomechanical parameters were measured using the Corvis ST preoperatively and at 1, 3, and 6 months postoperatively. Linear Mixed Models (LMM) were used to assess the independent effect of OZ size, adjusting for key baseline covariates and accounting for inter-eye correlation by including a random intercept for patient identifier (ID).
ResultsA total of 98 eyes were analyzed. Baseline analysis revealed a significant imbalance between the groups, with Group A (6.3 mm OZ) having higher myopia and a greater corneal stromal ablation depth (both P 0.05), with the sole exception of Ambrosio Relational Thickness Horizontal (ARTH) (P = 0.012). In contrast, several preoperative covariates, particularly corneal stromal ablation depth and preoperative central corneal thickness, were identified as significant predictors of multiple postoperative biomechanical parameters.
ConclusionThe independent effect of a 0.2 mm difference in optical zone size on corneal biomechanical properties after SMILE appears to be limited. After comprehensive statistical adjustment, the results suggest that preoperative anatomical and surgical parameters, especially corneal stromal ablation depth, are the primary drivers of the postoperative biomechanical response, rather than the minor difference in OZ size itself. This study underscores the importance of confounder adjustment in refractive surgery research and suggests that maximizing the residual stromal bed may be more critical for maintaining corneal biomechanical integrity than fine-tuning the optical zone diameter.

BackgroundIn 2022, 3.7% of U.S. adults currently smoked cigars. This study assesses cigar-smoking-attributable fractions in U.S. healthcare expenditures and associated annual healthcare expenditures overall and by payer, including publicly funded healthcare programs.
MethodsData were obtained from the 2000, 2005, 2010, and 2015–2017 National Health Interview Survey linked with corresponding panels from the Medical Expenditure Panel Survey data through 2018. The final sample (n = 53,733) was restricted to adults aged 25 + . Estimates from four-part models and data from the Personal Health Care component of the 2001–2018 National Health Expenditures Accounts were combined to estimate fractions of and annual healthcare expenditures attributable to cigar smoking. All models controlled for sociodemographic characteristics and health-related behaviors.
ResultsDuring 2001–2018, an estimated 1.8% (95% CI = 0.9%–3.4%) or $29.7 billion annually of U.S. healthcare expenditures could be attributed to cigar smoking. Most of this was funded by other third-party health insurance programs, a mix of private and public payers (e.g., Department of Veterans Affairs).
ConclusionsCigar smoking creates a preventable financial burden on the U.S. healthcare system. Health consequences associated with cigar smoking may remain after successful quitting. The findings underscore the importance of preventing initiation of cigar smoking and providing evidence-based cessation methods to reduce the health and economic burden of cigar smoking.

BackgroundAlthough gender and racial/ethnic trends and disparities are well documented among recipients of National Institutes of Health (NIH) research grant funding, little is known about the demographic trends and disparities within a critical subpopulation: NIH-funded medical school faculty.
MethodsThis paper analyzes a rich dataset of full-time medical school faculty and their NIH grants from 1970 to 2022 and examines temporal trends in the demographic distribution and relative representation (representation index) of NIH-funded medical school faculty by gender, race/ethnicity, and their intersections.
ResultsThis paper reports that, while the gender gap in NIH funding has narrowed, a gender gap remains, particularly among highly funded faculty. Further, trends disaggregated by both gender and race/ethnicity demonstrate the particularly low relative representation of Black and Hispanic NIH-funded faculty, specifically Black and Hispanic women, that persists over time. Notably, although Asian men and women are represented at similar rates among medical school faculty overall, a gender gap in favor of Asian men has become more pronounced over time among NIH-funded Asian faculty.
ConclusionsAlthough there are efforts to recognize a broader set of metrics for a successful research career, research grant funding remains key for establishing research independence, tenure, and promotion. Thus, our findings of ongoing disparities underscore the urgent need to identify effective strategies to advance gender and racial/ethnic equity within NIH-funded medical school faculty.

BackgroundParents of children with developmental delays (DD) often face significant challenges that affect their mental health and occupational balance. While early intervention services traditionally focus on child development, the occupational needs and well-being of parents remain underexplored. The EQo-Mental project aims to examine the association between parental mental health, occupational balance, and meaningful activity engagement, and to co-develop family-centred strategies that promote well-being in early intervention contexts.
MethodsThis sequential mixed-methods study includes two phases. The quantitative phase will involve approximately 700 parents of children aged 0–6 years attending early intervention centres in Alicante, Spain. This phase comprises two components: (1) the psychometric validation of the Spanish versions of two occupational measures—the Occupational Balance Questionnaire (OBQ-E) and the Engagement in Meaningful Activities Survey (EMAS)—and (2) a cross-sectional analysis examining associations between occupational and mental health outcomes. Participants will complete a sociodemographic questionnaire along with validated self-administered instruments assessing occupational balance, meaningful activity engagement, stress, anxiety, depression, and psychological well-being. In the qualitative phase, participatory sessions and focus groups will be conducted with a subsample of parents and key stakeholders to explore perceived occupational and mental health needs and to co-design actionable strategies for improving occupational balance and family well-being. Participant recruitment began in November 2023 and is ongoing; data collection is expected to be completed by October 2025.
AnalysesPsychometric analyses will first be conducted to evaluate the validity and reliability of the OBQ-E and EMAS. Next, descriptive analyses and multiple regression models adjusted for potential confounders will be used to explore associations between occupational and mental health variables. Phase 2 consists of a participatory-action research process, including discussion groups and a multi-stakeholder focus group. Qualitative data will be analysed using reflexive thematic analysis.
OutcomesFindings from EQo-Mental will inform the design of evidence-based, family-centred strategies that support occupational balance, parental well-being, and engagement in meaningful activities. By addressing the occupational needs of parents, the project seeks to foster more resilient families and strengthen early intervention services through an inclusive, occupation-focused approach.

Males in socially monogamous species can achieve reproductive success through multiple tactics– by defending paternity within the social nest and siring extra-pair offspring, or both. Previous studies have found that sperm morphology may differentially affect fertilization success in extra-pair compared to within-pair matings; therefore, we explored whether sperm morphological traits can predict the probability of success within components of reproductive success. Here, we measured sperm component traits (head length and flagellum length) and derived traits (total length and flagellum:head ratio) in free-living Mountain White-crowned Sparrows (Zonotrichia leucophrys oriantha) and examined how these morphological traits relate to extra-pair and within-pair reproductive components of reproductive success. We found no evidence for correlations between sperm morphology and total seasonal reproductive success. However, we did find that sperm morphology appeared to be associated with whether a male was successful at acquiring extra-pair offspring or defending his own paternity within his nest: males that achieved extra-pair success had longer flagella and longer total length of sperm cells compared to males that did not sire outside of their social nest. In contrast, males that successfully defended all paternity within their social nest tended to have shorter heads and larger flagellum:head ratios compared to males that lost paternity in their social nest. While these patterns suggest that different sperm traits may be linked to success in different components of reproductive success, they should be interpreted with caution given the exploratory nature of this study and limited sample size, and further investigation is warranted.by Cyndirela Chadambuka, Prossy Kiddu Namyalo, Rhea Raghunauth, Navya Arora, Fiona Kouyoumdjian, Beverley M.

The risk of gender-based violence (GBV) against migrant women is largely exacerbated by precarious employment opportunities available to them as they go through the resettlement process. Despite the risk that the connection of precarious employment and GBV pose to migrant women’s health and wellbeing, critical gaps exist in literature. Our scoping review sought to identify and synthesize evidence on the interconnectedness of GBV and precarious employment among migrant women. Six electronic databases were searched for empirical literature and two reviewers independently conducted title/abstract and full text screening of studies that met the inclusion criteria. Data synthesis was guided by the intersectionality theory and the Feminist Political Economy framework. 50 articles met the criteria for inclusion in this review. Our findings reveal that precarious employment plays both a catalytic and consequential role in GBV. Findings highlighted how post-migration shifts in gender roles, schedule unpredictability leading to work-life imbalance, and debt bondage trap migrant women in cycles of exploitation and abuse. Few studies highlighted how human trafficking is intertwined with precarious labor markets, where the exploitation and abuse of migrant women mirror the characteristics of human trafficking. This review underscores the urgent need for integrated policy responses that are not only focused on individual supports but also address the structural drivers or labor precarity and protect migrant women from GBV and human trafficking. By applying an intersectional lens, policies and intervention programs can tackle systemic oppression across economic, and social systems essential in reducing exploitation and abuse to advance migrant women’s wellbeing.by Yi-Hua Wu, Chia-Ing Li, Chiu-Shong Liu, Chih-Hsueh Lin, Shing-Yu Yang, Cheng-Chieh Lin, Tsai-Chung Li
Glycemic variability (GV) is an emerging biomarker of glycemic control and may be a predictor for lung function impairment in persons with type 2 diabetes mellitus (T2DM). However, the associations between GV and lung function variables and lung function impairment have not been fully evaluated. The objective of this study was to assess the associations of glycemic variability (GV) with lung function impairment in persons with T2DM. A follow-up study was conducted on the data of 3,108 subjects collected from 2001 to 2020 using the diabetes care management program database in Taiwan. GV in fasting plasma glucose (FPG) was calculated using standard deviation (SD), average real variability (ARV), coefficient of variation (CV), variability independent of the mean (VIM), and slope of 1-year repeated measurements. A ratio of forced expiratory volume in 1 s (FEV1) to forced vital capacity (FVC) less than 0.70 was used to define lung function impairment. Multivariable linear and logistic regression models were applied to explore the relationships of GV with lung function variables and lung function impairment. A total of 359 (11.6%) subjects were defined as having lung function impairment. After multivariable adjustment, FPG‐SD, FPG-CV, FPG-AVR, FPG-VIM and were found to be negatively linked with FEV1, % predicted FEV1, and FVC but not FEV1/FVC. Relative to those for the first tertile, the odds ratios (ORs) of lung function impairment for the second and third tertiles were 1.37 (95% confidence interval [CI]: 1.01, 1.87) and 1.51 (1.10, 2.08) for FPG-CV, respectively; 1.59 (1.16, 2.17) and 1.73 (1.24, 2.40) for FPG‐SD, respectively; and 1.57 (1.15, 2.13) and 1.69 (1.22, 2.33) for FPG-AVR, respectively. GV, measured by CV, SD, VIM, and VIM, is linked with lung function impairment and all lung function variables, except for FEV1/FVC ratio. GV may serve as a useful biomarker for assessing lung function impairment in persons with T2DM.by Xiaoliang Wan, Feiyao Deng, Xue Bai, Chenxi Xiang, Chuan Xu, Linxiao Qiu
Dysregulated serum chloride levels are prevalent in critically ill patients. However, their clinical impact remains unclear. This first systematic review and meta-analysis quantified the prevalence of hypochloremia and hyperchloremia, and their associations with mortality and acute kidney injury (AKI) in critically ill populations. We searched PubMed, Embase, Web of Science, and the Cochrane Library for studies reporting hyperchloremia prevalence or outcomes in adult ICU patients until August 2025. Statistical analyses were conducted using Stata v16.0, and study quality was assessed using the Newcastle-Ottawa Scale. 34 studies (n = 175,021 patients) were included. The aggregated prevalence of hyperchloremia was 34% (95% CI [26%−43%]) and hypochloremia was 14% (95% CI [1%−28%]). Meta-analysis demonstrated that both hyperchloremia and hypochloremia were significantly associated with increased mortality, conferring a 28% (OR = 1.28, 95% CI [1.08–1.52]) and 55% (OR = 1.55%, 95% CI [1.33–1.81]) elevated risk for mortality, respectively. Crucially, a dose-response analysis revealed a non-linear relationship between serum chloride levels and mortality, confirming that the risk is independently elevated at both extremes. Furthermore, hyperchloremia was linked to an increased risk of AKI (OR = 1.40, 95% CI [1.07–1.85]). These findings establish dysregulated serum chloride as a common and clinically significant biomarker, underscoring the necessity of monitoring and managing both high and low chloride levels in critically ill patients. Future large-scale studies are warranted to validate these results and elucidate the mechanistic pathways linking chloride dysregulation to such adverse outcomes.by Abate Atimut Dereje, Dereje Geleta, Tadesse Menjetta, Abinet Takele, Susana Vaz Nery, Techalew Shimelis
BackgroundEarly diagnosis and prompt treatment of malaria cases are a crucial component of curative and preventive interventions. There have been reports of healthcare workers overprescribing antimalarial agents against guidelines, but the barriers they face in adhering to the guidelines are not well studied. This study aimed to investigate barriers to adherence to guidelines in prescribing antimalarial drugs in public healthcare facilities in Arba Minch, South Ethiopia.
MethodA cross-sectional descriptive exploratory qualitative method was employed. We included ten participants from public healthcare facilities, including health centres, a hospital, a city health office, and a zonal health bureau. A key informant interview technique was used to collect data. All interviews were audio-recorded, transcribed, and analyzed. Data analysis was performed using ATLAS.ti, version 7.5 software. The results were presented thematically and narrated to support the main themes.
ResultsPublic healthcare facilities primarily used blood smear microscopy to test all malaria-suspected patients. However, in cases of microscopy service interruptions or when confirming negative results, rapid diagnostic tests (RDTs) were employed in some facilities. Limited availability of microscopes and reagents, and electric power interruptions hindered reliable microscopy services. Drug stock-outs, patient expectations for antimalarial drugs, self-treatment, and delayed care-seeking are barriers to adherence to malaria treatment guidelines. The main reason for non-adherence to withholding antimalarial drugs after negative tests was greater trust in clinical findings over laboratory results. Confidence in experience contributed to trust in clinical judgment, while perceived inexperience and negligence, inconsistent RDT and microscopy results, and poor-quality control assessment results undermined trust in laboratories. Despite supporting the guidelines, study participants emphasized the need for flexibility to allow empirical treatment and highlighted the lack of training and mentoring for healthcare workers.
ConclusionTo improve adherence to malaria treatment guidelines, it is essential to ensure consistent lab operations, enhance quality assurance, maintain effective communication between lab personnel and prescribers, and provide healthcare and patient education. Implementing training and mentoring programs and promoting evidence-based practices are also crucial.

BackgroundCivil Registration and Vital Statistics (CRVS) systems are essential for governance, public health, and achieving SDGs however, gender gaps limit women’s access to rights and services, with under-registration of female vital events reinforcing their invisibility and distorting gender-responsive policies.
ObjectivesThis study examines the drivers of low female death registration across India’s States and Union Territories, focusing on the roles of age, gender and wealth, with an aim to inform policies to strengthen CRVS systems and reduce gender disparities in vital statistics.
MethodsThe study utilizes data from NFHS-5 (2019–2021 for examining the factors associated with female death registration. Multivariable logistic regression models have been used to examine the impact of socio-economic and demographic factors on female death registration in India.
FindingsThe results highlight a significant gender gap in death registration (73% male vs. 64% female). The gap is widest in states like Bihar and Uttar Pradesh, while states like Kerala and Goa report near universal registration for both sexes. Gender gaps in housing and land ownership align with gaps in death registration, suggesting a strong association between asset ownership and registration. The results highlight association between wealth and death registration, with rates rising across quintiles for both sexes; however males consistently have higher registration rates. Among the poorest, the gap is widest which narrows down in the richest group. A gender gap in death registration persists across all age groups in India, beginning early, widening during working ages, and continuing into old age; while registration rates improve with age and wealth, women especially among the poorest remain under-registered, particularly in early and later life stages.
ConclusionsWomen in India encounter barriers to civil registration, and improving death registration demands systemic reforms, digital advancements, and community engagement Strengthening political commitment, collaboration, and public awareness will ensure inclusive, accurate records, enhancing CRVS for governance and policy.

Inflammation plays a crucial role in homeostasis and defense responses; however, exaggerated and chronic inflammation contribute to the development and worsening of various diseases. Acanthospermum australe (Loefl.) Kuntze (A. australe) is a medicinal plant traditionally used to alleviate inflammation. However, the anti-inflammatory activity of this plant has not yet been explored. This study aimed to evaluate the immunomodulatory activity of this species using network pharmacology, UPLC-ESI-MS/MS analysis, and in vitro assays. Network pharmacology analysis revealed the involvement of immune system processes, and among the main targets of A. australe related to inflammation were innate immune responses, toll-like receptors (TLRs), and T cell receptor signaling pathways. A methanolic extract was prepared and analyzed using UPLC-ESI-MS/MS, and 15 compounds were detected. Additionally, the potential targets of A. australe predicted by network pharmacology analysis were validated in vitro using monocytic THP-1 cells and splenocytes. The RT-qPCR analysis indicated that A. australe significantly inhibited the production of pro-inflammatory cytokines IL-1β, IL-6, and TNF-α, as well as chemokine CCL-2, in lipopolysaccharide (LPS)-stimulated cells. Finally, the extract significantly decreased concanavalin A (ConA)-induced T cell proliferation. Overall, our study provides evidence for the anti-inflammatory effects of this species and highlights its mechanisms of action.by Caroline Gatwiri Gitonga, Charles Githinji, Boniface Chege, Frederick Bukachi, Peter Waweru
ObjectiveCalcium carbide-derived acetylene is widely used as an artificial fruit ripening agent despite its potential health risks. This study aimed to investigate the effects of sub-chronic exposure to crude acetylene on cardiometabolic parameters using a rodent model.
MethodsTwenty-four male Sprague Dawley rats were randomized into four groups: control (no exposure) and three test groups exposed to 58,000 ppm crude acetylene for 10, 30, or 60 minutes daily over 42 days. Body weight, fasting blood glucose, oral glucose tolerance, hepatic triglyceride levels, adipose tissue mass, liver enzyme activity, and oxidative stress markers were assessed. Histopathological analysis of liver tissue was also conducted.
ResultsAcetylene exposure did not significantly alter body weight but led to dose-dependent increases in central adiposity, hepatic triglycerides, and markers of oxidative stress. Higher doses were also associated with impaired glycemic control, elevated liver enzyme levels, and increased free heme concentration in plasma, suggesting oxidative damage and hemolysis. Histological analysis revealed central vein congestion and hepatic structural alterations in exposed groups.
ConclusionSub-chronic inhalation of crude acetylene induced metabolic dysfunction characterized by impaired glucose regulation, hepatic steatosis, and oxidative stress, despite no changes in overall body weight. These findings highlight the potential health risks associated with acetylene exposure and underscore the need for regulatory measures to limit its use in fruit ripening.

This systematic review examined the effectiveness of perinatal interventions aimed at preventing infant removals, with attention to service features, implementation barriers, and enablers. We searched six electronic databases and 15 relevant websites for peer reviewed studies published between 2014 and 2024. Eligible studies evaluated interventions targeting pregnant parents at risk of having another child removed and reported on infant removal outcomes. Independent reviewers screened studies using Covidence. A total of 256 records were obtained, of which six peer reviewed studies covering eight interventions, involving 3,254 pregnant women and 20 professionals met the inclusion criteria. Three studies included comparison groups, including only one randomized controlled trial. Five studies assessed program-level interventions, and one study evaluated a policy change. Risk of bias was assessed using the Mixed Methods Appraisal Tool (MMAT). Two of the three comparative studies indicated that targeted interventions may help reduce infant removals. Four of the six studies highlighted that trauma-informed, relationship-based, and multidisciplinary approaches delivered during pregnancy were associated with reductions in infant removals and improvements in maternal wellbeing, housing stability, substance use, and service engagement. Facilitators of successful implementation included continuity of care, culturally safe and non-judgmental support, and flexible services tailored to family needs. Common barriers were late referrals, limited intervention timelines, mistrust of services particularly among families with prior removals and insecure funding that constrained scale and sustainability. Despite generally positive outcomes, the evidence base remains weak due to small samples, limited diversity, lack of comparison groups, and short follow-up periods. This first systematic review of perinatal interventions for preventing infant removals highlights the need for long term, inclusive, comparative research. It underscores the importance of embedding early, holistic support in routine services and offers valuable insights for policy and practice on supporting parents with complex needs within the child protection system.
