Background: The human gut microbiome changes considerably over time. Previous studies have shown that gut microbiome profiles correlate with multiple metabolic traits. As disease development is likely a lifelong process, evidence gathered at different life stages would help gain a better understanding of this correlation.

The prevalence of urinary incontinence (UI) in older women in low- and middle-income countries (LMICs) is not well understood. We conducted a rapid literature review to assess the burden of UI in this population and contextualize findings from a household survey of women aged 40 and older in Nouna, in northwestern Burkina Faso. The rapid review included 21 survey articles.

Background: This study aims to investigate the associations between signal-level physical activity (PA) features derived from wrist accelerometry data and cognitive status in older adults, and to evaluate their potential predictive value when combined with demographics.

Methods: We analyzed PA data from 3,363 older adults (NHATS: n = 747; NHANES: n = 2,616), with each participant contributing a complete 3-day continuous activity sequence. We extracted the most relevant PA features associated with cognitive function using feature engineering and recursive feature elimination.

January 2025

Institute of Public Health, Medical Decision Making and Health Technology Assessment, Department of Public Health, Health Services Research and Health Technology Assessment, UMIT TIROL Private University for Health Sciences and Technology GmbH, Hall, Austria.

Introduction: Maintaining and optimizing quality of life (QoL) is a central issue and one of the most important goals in therapy for patients with chronic diseases, such as diabetes mellitus (DM). Despite its importance, there is little data on the QoL of patients with DM in Austria. The objective of this study was to extend an established population-based cohort, the Diabetes-Landeck cohort, by including patient-reported outcomes.

Human Flourishing Program, Institute for Quantitative Social Science, Harvard University, Cambridge, Massachusetts; Department of Epidemiology, Harvard T.H. Chan School of Public Health, Boston, Massachusetts; Department of Biostatistics, Harvard T.H. Chan School of Public Health, Boston, Massachusetts.

Purpose: Intergovernmental organizations, such as the World Health Organization, policymakers, scientists, and the public alike are recognizing the importance of loneliness for health/well-being outcomes. However, it remains unclear if loneliness in adolescence shapes health/well-being in adulthood. We examined if increase in loneliness during adolescence was associated with worse health/well-being in adulthood, across 41 outcomes.

Heat exposure in outdoor work environments poses risks to worker health and productivity. Engineering solutions like cool surfaces that increase surface albedo and reduce temperatures may help mitigate these impacts. We conducted detailed micrometeorological modeling to analyze surface characteristics and heat exposure for outdoor workers at San Francisco International Airport (SFO) under current conditions and three hypothetical albedo-increase scenarios.

Spatially resolved transcriptomics enable comprehensive measurement of gene expression at subcellular resolution while preserving the spatial context of the tissue microenvironment. While deep learning has shown promise in analyzing SCST datasets, most efforts have focused on sequence data and spatial localization, with limited emphasis on leveraging rich histopathological insights from staining images. We introduce GIST, a deep learning-enabled gene expression and histology integration for spatial cellular profiling.

Genetic and genomic variation among microbial strains can dramatically influence their phenotypes and environmental impact, including on human health. However, inferential methods for quantifying these differences have been lacking. Strain-level metagenomic profiling data has several features that make traditional statistical methods challenging to use, including high dimensionality, extreme variation among samples, and complex phylogenetic relatedness.

Narrative accounts have documented the potential for suffering to degrade a person's well-being by undermining their sense of meaning in life, but few studies have investigated this among nonclinical samples living in non-Western contexts of the Global South. Leveraging data from a set of three-wave longitudinal studies with younger Indonesian (Study 1: Wave 1 [December 2020], Wave 2 [January 2021], Wave 3 [February 2021]; N = 620) and Colombian adults (Study 2: Wave 1 [August/September 2021], Wave 2 [October/November 2021], Wave 3 [February 2022]; N = 2626), the present research used causal mediation methods within a counterfactual framework to examine whether the associations between suffering (Wave 1) and subsequent anxiety symptoms, depression symptoms, and general mental health (Wave 3) are mediated by meaning in life (Wave 2). Mediation analyses in both studies provided some evidence indicating that overall suffering (Wave 1) is indirectly associated with worse subsequent mental well-being on all three outcomes (Wave 3) via lower meaning in life (Wave 2).

The renin-angiotensin-aldosterone system and salt sensitivity of blood pressure offer new insights in obesity phenotypes.

Obesity (Silver Spring)

January 2025

Division of Endocrinology, Diabetes and Hypertension, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts, USA.

Objective: Individuals who have metabolically healthy overweight/obesity (MHOO) do not have cardiometabolic complications despite an elevated BMI. Renin-angiotensin-aldosterone system (RAAS) activation and salt sensitivity of blood pressure (SSBP) are cardiovascular disease (CVD) risks, which are increased in individuals with higher BMI values. Little is known about the differences in RAAS activation and SSBP between MHOO and metabolically unhealthy overweight/obesity (MUOO) phenotypes.

Background: The volume and proportion of surgeries occurring in outpatient settings has increased. However, the growth and distribution of outpatient surgical institutions, namely ambulatory surgery centers (ASCs) and hospital-based outpatient surgical departments (HOPDs), remains understudied in rural areas.

Methods: We used descriptive statistics and a multivariate logistic regression to assess the growth and distribution of ASCs and HOPDs in rural areas from 2010 to 2020, leveraging the Area Health Resources Files and American Community Survey.

Channing Division of Network Medicine, Department of Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, 02115, USA.

Due to highly personalized biological and lifestyle characteristics, different individuals may have different metabolite responses to specific foods and nutrients. In particular, the gut microbiota, a collection of trillions of microorganisms living in the gastrointestinal tract, is highly personalized and plays a key role in the metabolite responses to foods and nutrients. Accurately predicting metabolite responses to dietary interventions based on individuals' gut microbial compositions holds great promise for precision nutrition.

Adenocarcinoma, the most prevalent type of colorectal cancer, makes up roughly 95 % of all cases and is associated with a notably high mortality rate. Owing to the various risk factors which might include personal choices and habits or genetic factors, the risk of developing the cancer for every individual might vary. However, given the statistics, the rate of acquiring the disease is pretty high.

The incidence of type 2 diabetes has risen globally, in parallel with the obesity epidemic and environments promoting a sedentary lifestyle and low-quality diet. There has been scrutiny of ultra-processed foods (UPFs) as a driver of type 2 diabetes, underscored by their increasing availability and intake worldwide, across countries of all incomes. This narrative review addresses the accumulated evidence from investigations of the trends in UPF consumption and the relationship with type 2 diabetes incidence.

Background: Federal policy impact analyses in the United States do not incorporate the potential economic benefits of adolescent mental health policies. Understanding the extent to which economic benefits may offset policy costs would support more effective policymaking. This study estimates the relationship between adolescent psychological distress and later health and economic outcomes and uses these estimates to determine the potential economic effects of a hypothetical policy.
