The expected polygenic risk score (ePRS) framework: an equitable metric for quantifying polygenetic risk via modeling of ancestral makeup.

Polygenic risk scores (PRSs) depend on genetic ancestry due to differences in allele frequencies between ancestral populations. This leads to implementation challenges in diverse populations. We propose a framework to calibrate PRS based on ancestral makeup.

Prevalence of chlamydia, gonorrhoea, and trichomoniasis among male and female general populations in sub-Saharan Africa from 2000-2024: A systematic review and meta-regression analysis.

Background: Sub-Saharan Africa (SSA) has the highest sexually transmitted infection (STI) prevalence globally, but information about trends and geographic variation is limited by sparse aetiologic studies, particularly among men. This systematic review assessed chlamydia, gonorrhoea, and trichomoniasis prevalence by sex, sub-region, and year, and estimated male-to-female prevalence ratios for SSA.

Methods: We searched Embase, MEDLINE, Global Health, PubMed, and African Index Medicus for studies measuring STI prevalence among general populations from January 1, 2000, to September 17, 2024.

Factors and Outcomes Associated With Using Scratch-Cooked, Organic, and Locally Grown Foods in School Meals in California.

Background: Incorporating scratch-cooked, organic, and locally grown foods into school meal programs can enhance meal quality and support local food systems.

Methods: 430 California school food authorities were surveyed to (1) evaluate their use of scratch-cooked, organic, and locally grown foods in their programs; (2) identify demographic and operational characteristics related to this use; and (3) analyze the relationship between serving more of these foods and perceived barriers to student meal participation. Poisson and logistic regression models, adjusted for SFAs' demographic characteristics, were used.

Implementation research logic model in the design and execution of eHealth innovations for maternal and newborn healthcare in Ethiopia.

Background: The use of eHealth innovations is becoming increasingly important in improving health outcomes, especially for maternal and newborn health. However, planning and executing these innovations can be challenging due to their complex nature. To provide guidance and clarity on implementation approaches, researchers need to use implementation research (IR) tools.

The additive effect of the stress hyperglycemia ratio on type 2 diabetes: a population-based cohort study.

Background: The stress hyperglycemia ratio (SHR) has recently gained attention as a marker for acute hyperglycemia, which has been linked to adverse clinical outcomes. However, its independent role in the development of type 2 diabetes (T2D) remains understudied. This cohort study aimed to assess the association between SHR and the incidence of T2D.

High organofluorine concentrations in municipal wastewater affect downstream drinking water supplies for millions of Americans.

Wastewater receives per- and polyfluoroalkyl substances (PFAS) from diverse consumer and industrial sources, and discharges are known to be a concern for drinking water quality. The PFAS family includes thousands of potential chemical structures containing organofluorine moieties. Exposures to a few well-studied PFAS, mainly perfluoroalkyl acids (PFAA), have been associated with increased risk of many adverse health outcomes, prompting federal drinking water regulations for six compounds in 2024.

Human mobility and malaria risk in peri-urban and rural communities in the Peruvian Amazon.

Background: While the global burden of malaria cases has decreased over the last two decades, the disease remains a major international threat, even on the rise in many regions. More than 85% of Peruvian malaria cases are in the Amazonian region of Loreto. Internal mobility primarily related to occupation is thought to be primarily responsible for maintaining endemicity and introducing and reintroducing malaria parasites into areas of anophelism, a challenge for malaria eradication.

Evaluating hypothetical prevention strategies for internalizing symptoms in the general population and at-risk children.

Objective: Specific modifiable factors (e.g., screen time [ST], sleep duration, physical activity, or social connections) are targets for reducing depression risk in adults.

Invited Commentary: Why use methods that require proportional hazards?

We recently questioned the utility of testing for proportional hazards in survival analysis. Here we expand on why the proportional hazards assumption is both implausible and unnecessary in most medical studies, particularly in randomized trials. We conclude that using survival analysis methods that do not rely on proportional hazards is typically the preferred course of action.

Exploring novel determinants of exercise behavior: a lagged exposure-wide approach.

Unlabelled: Many middle-aged to older adults do not engage in regular exercise at all, despite its importance for healthy aging. Extensive research grounded in behavioral and social science theories has identified numerous determinants of exercise. However, few studies used an exposure-wide approach, a data-driven exploratory method particularly useful for identifying novel determinants.

DOME: Directional medical embedding vectors from Electronic Health Records.

Motivation: The increasing availability of Electronic Health Record (EHR) systems has created enormous potential for translational research. Recent developments in representation learning techniques have led to effective large-scale representations of EHR concepts along with knowledge graphs that empower downstream EHR studies. However, most existing methods require training with patient-level data, limiting their abilities to expand the training with multi-institutional EHR data.

Large floods drive changes in cause-specific mortality in the United States.

Flooding greatly endangers public health and is an urgent concern as rapid population growth in flood-prone regions and more extreme weather events will increase the number of people at risk. However, an exhaustive analysis of mortality following floods has not been conducted. Here we used 35.

Updated Geriatrics Competencies for Graduating Medical Students: Training Physicians to Provide Age-Friendly Care.

Purpose: Medical student education in geriatrics is a critical need for every doctor-in-training as the population ages, with fewer than 7,000 geriatricians, and older patients, who now approach 20% of the U.S. population, having unique health care needs.

Demographic, social and health system factors associated with maternal mortality in Pakistan: A nested case-control study.

Background: Pakistan has experienced a significant reduction in maternal mortality with a decline of 33 percent between 2006 and 2019. However, the country still grapples with a high number (186 per 100,000 live births) of maternal deaths each year. This study aims to identify socio-demographic and health system related factors associated with maternal mortality.

US State Public Health Agencies' Use of Twitter From 2012 to 2022: Observational Study.

Background: Twitter (subsequently rebranded as X) is acknowledged by US health agencies, including the US Centers for Disease Control and Prevention (CDC), as an important public health communication tool. However, there is a lack of data describing its use by state health agencies over time. This knowledge is important amid a changing social media landscape in the wake of the COVID-19 pandemic.

Fatty acids and telomere length.

Purpose Of Review: This narrative review includes the latest clinical and preclinical evidence on fatty acid exposure and telomere length, a widely accepted hallmark of aging.

Recent Findings: A large body of literature focused on n-3 (omega-3) polyunsaturated fatty acids (PUFAs). Observational studies reported beneficial associations with telomere length for self-reported consumption of n-3 PUFA-rich foods; for estimated intake of n-3 PUFAs; and for n-3 PUFAs blood-based biomarkers in most (but not all) studies involving lipidomics, a promising tool in the field.

Religion and flourishing among Afro-Trinidadians: the influence of proneness to guilt/shame and forgiveness by God on the relationship between religious commitment and health.

Background: Religiousness has been consistently linked to positive health outcomes and flourishing, yet the underlying mechanisms are complex and not well-understood. The forgiveness and relational spirituality model offers a framework to explore the moderated mediation among religious commitment, health, and forgiveness by God. Understanding these relationships among university students and community residents in Trinidad and Tobago can provide valuable insights into the role of religiousness in promoting wellbeing.

Heparin and Bivalirudin in Percutaneous Coronary Intervention for Acute Coronary Syndromes: A Review Article.

Acute coronary syndrome (ACS) is one of the most common leading global causes of mortality, encompassing ST-segment elevation myocardial infarction (STEMI), non-ST-segment elevation myocardial infarction (NSTEMI), and unstable angina (UA). Percutaneous coronary intervention (PCI) has become a pivotal therapeutic approach for ACS, underscoring the importance of anticoagulation strategies. Among the commonly employed anticoagulants in PCI, heparin and bivalirudin take precedence, with heparin serving as the archetypal choice.

The Future Hospital in Global Health Systems: The Future Hospital as an Entity.

Health care is changing rapidly. Hospitals are, and will remain, an essential setting to deliver it. We discuss how to maximise the benefits of hospitals in the future in different geographic and health system settings, highlighting a series of cross-cutting issues.

Profiling lateral gene transfer events in the human microbiome using WAAFLE.

Lateral gene transfer (LGT), also known as horizontal gene transfer, facilitates genomic diversification in microbial populations. While previous work has surveyed LGT in human-associated microbial isolate genomes, the landscape of LGT arising in personal microbiomes is not well understood, as there are no widely adopted methods to characterize LGT from complex communities. Here we developed, benchmarked and validated a computational algorithm (WAAFLE or Workflow to Annotate Assemblies and Find LGT Events) to profile LGT from assembled metagenomes.
