Insulin secretion, sensitivity, and clearance in normoglycemic Black and White adults with parental type 2 diabetes: association with incident dysglycemia.

Introduction: Ethnic disparities in the prevalence and pathophysiology of type 2 diabetes are well documented, but prospective data on insulin dynamics vis-à-vis pre-diabetes/early dysglycemia risk in diverse populations are scant.

Research Design And Methods: We analyzed insulin secretion, sensitivity, and clearance among participants in the Pathobiology of Prediabetes in a Biracial Cohort (POP-ABC) study. The POP-ABC study followed initially normoglycemic offspring of parents with type 2 diabetes for 5.

Poststroke hyperglycemia dysregulates cap-dependent translation in neural cells.

Aims: Post stroke hyperglycemia has been shown to deter functional recovery. Earlier findings have indicated the cap-dependent translation regulator 4E-BP1 is detrimentally upregulated in hyperglycemic conditions. The present study aims to test the hypothesis that hyperglycemic ischemic reperfusion injury (I/R) affects normal protein translation poststroke.

Comparative Efficacy of Continuous Positive Airway Pressure and Antihypertensive Medications in Obstructive Sleep Apnea-Related Hypertension: A Narrative Review.

Introduction: Obstructive sleep apnea (OSA) presents a significant global health concern, affecting a substantial portion of the population, particularly among young and middle-aged adults.

Aim: This review aims to assess the efficacy of continuous positive airway pressure (CPAP) compared to antihypertensive medications in managing OSA-related hypertension.

Methods: A comprehensive literature search was conducted across multiple databases, yielding studies published from 2000 to March 2024 that investigated CPAP, antihypertensives, or their combination therapy in OSA patients.

Geocultural differences in pre-schooler sleep profiles and family practices: an analysis of pooled data from 37 countries.

Study Objectives: To examine 1) multidimensional sleep profiles in pre-schoolers (3-6 years) across geocultural regions and 2) differences in sleep characteristics and family practices between Majority World regions (Pacific Islands, Sub-Saharan Africa, Eastern Europe, Northeast Asia, Southeast Asia, South Asia, the Middle East and North Africa, Latin America) and the Minority World (the Western world).

Methods: Participants were 3507 pre-schoolers from 37 countries. Nighttime sleep characteristics and nap duration (accelerometer: n=1950) and family practices (parental questionnaire) were measured.

Bat Cutaneous Microbial Assemblage Functional Redundancy Across a Host-Mediated Disturbance.

Understanding the processes and factors that influence the structure of host-associated microbial assemblages has been a major area of research as these assemblages play a role in host defense against pathogens. Previous work has found that bacterial taxa within bat cutaneous microbial assemblages have antifungal capabilities against the emerging fungal pathogen, Pseudogymnoascus destructans. However, our understanding of natural fluctuations in these cutaneous microbial assemblages over time due to shifts in host habitat is lacking.

Toluene is a cerebral artery constrictor acting via BK channels.

Acute intoxication by toluene usually follows intentional inhalation to achieve a "high", which may lead to repeated use due to toluene's reinforcing properties. In both acute and chronic intoxication brain function is primarily affected. Neuronal and glial elements participate in toluene's reinforcing properties and chronic toxicity, yet the targets underlying acute toxicity remain unknown.

The mediating role of social support on the link between adverse childhood experiences and adult mental health.

Adverse childhood experiences (ACEs) have been associated with adult mental health, especially anxiety and depression. We aimed to explain these relationships by investigating perceived social support as a mediating factor. In this model, it is proposed that individuals who experience more ACEs will have less perceived social support in adulthood, which in turn will increase reported anxiety and depression symptoms.

Two Blatter Radicals Face-to-Face: A Constrained Diradical Architecture.

Cofacial arrangement of two Blatter radicals enforced by the -naphthalene scaffold represents a new approach to stable diradicals with strong through-space interactions. Two stereoisomers of the naphthalene-diradicals, and , are investigated by XRD, VT-EPR, UV-vis, electrochemical, kinetic, and DFT methods. In solutions, both stereoisomers exist as open-shell singlets with Δ = -3.

Metals and metalloids pollution levels, partitioning, and sources in the environmental compartments of a small urban catchment in Moscow megacity.

This study examines the contamination levels and sources of 32 metals and metalloids (MMs) in environmental compartments (roadside soil, road dust, and river suspended sediments) of a small urbanized river catchment located in Moscow megacity. MMs partitioning between particle size fractions (PM, PM, and PM) was analyzed by ICP-MS and ICP-AES methods. The pollution level of particle size fractions with MMs decreases in the following series: road dust > suspended sediments > soils.

Machine Learning Correlation of Electron Micrographs and ToF-SIMS for the Analysis of Organic Biomarkers in Mudstone.

The spatial distribution of organics in geological samples can be used to determine when and how these organics were incorporated into the host rock. Mass spectrometry (MS) imaging can rapidly collect a large amount of data, but ions produced are mixed without discrimination, resulting in complex mass spectra that can be difficult to interpret. Here, we apply unsupervised and supervised machine learning (ML) to help interpret spectra from time-of-flight-secondary ion mass spectrometry (ToF-SIMS) of an organic-carbon-rich mudstone of the Middle Jurassic of England (UK).

Suppressing the Inflammatory Prostaglandin Signaling after Thrombotic Stroke Ameliorates Ischemic Brain Injury and Facilitates Poststroke Recovery.

Acute cerebral ischemia is a leading cause of death and disability, particularly among old adults. The narrow therapeutic window and risk of hemorrhagic transformation largely limit patient eligibility for the current treatment. The neuroinflammatory signaling pathway involving the prostaglandin E2 (PGE) receptor subtype EP2 has now been clarified to contribute to the secondary neurotoxicity following ischemic stroke.

Predicting responsiveness to GLP-1 pathway drugs using real-world data.

Background: Medications targeting the glucagon-like peptide-1 (GLP-1) pathway are an important therapeutic class currently used for the treatment of Type 2 diabetes (T2D). However, there is not enough known about which subgroups of patients would receive the most benefit from these medications.

Objective: The goal of this study was to develop a predictive model for patient responsiveness to medications, here collectively called GLP-1 M, that include GLP-1 receptor agonists and dipeptidyl peptidase-4 (DPP4) inhibitors (that normally degrade endogenously-produced GLP-1).

Cognition, function, and mood post-COVID-19: Comparative analysis using the health and retirement study.

Millions of Americans endure post-COVID conditions (PCC), yet research often lacks pre-illness measurements, relying primarily on follow-up assessments for analysis. The study aims to examine the prevalence of PCC, including cognitive impairment, functional limitation, and depressive symptoms, along with relevant risk factors, while controlling for individuals' pre-illness status measured in 2018. A cross-sectional retrospective study utilized the 2018 and 2020 Health and Retirement Study surveys.

A Decade of Achievements: International Society of Paediatric Oncology Baseline Nursing Standards.

The six International Society of Paediatric Oncology (SIOP) Baseline Nursing Standards provide the first evidence-based framework for assessing and improving pediatric oncology nursing practice settings in low-, middle-, and high-income countries. Over the past 10 years, the standards have been translated to six languages, endorsed by 13 organizations, surveyed at 101 hospitals in 54 countries, and initiatives have been documented at over 63 institutions in 31 countries. Going forward, the SIOP Nursing Network's Baseline Standards Special Interest Group has established a 5-year strategic plan to guide advocacy, research, and standards implementation through global multidisciplinary collaboration.

Qualitative Research Leaders: Evaluation of Pilot Global Pipeline Program.

Qualitative research methods are central to understanding many public health problems. However, capacity building for qualitative research is globally skewed toward high-income countries, with a significant skills deficit in low- and middle-income countries (LMICs). To address this imbalance and provide a model program, we developed the Qualitative Research Leaders (QRL) program, a pipeline program to increase qualitative research capacity in LMIC institutions and foster leadership in qualitative research.

Functional annotation of regulatory elements in rainbow trout uncovers roles of the epigenome in genetic selection and genome evolution.

Rainbow trout (RBT) has gained widespread attention as a biological model across various fields and has been rapidly adopted for aquaculture and recreational purposes on 6 continents. Despite significant efforts to develop genome sequences for RBT, the functional genomic basis of RBT's environmental, phenotypic, and evolutionary variations still requires epigenome reference annotations. This study has produced a comprehensive catalog and epigenome annotation tracks of RBT, detecting gene regulatory elements, including chromatin histone modifications, chromatin accessibility, and DNA methylation.

Hepatic Steatosis and Fibrosis, Cardiorespiratory Fitness, and Metabolic Mediators in the Community.

Background And Aims: Individuals with steatotic liver disease (SLD) are at high cardiovascular disease (CVD) risk, but approaches to characterise and mitigate this risk are limited. By investigating relations, and shared metabolic pathways, of hepatic steatosis/fibrosis and cardiorespiratory fitness (CRF), we sought to identify new avenues for CVD risk reduction in SLD.

Methods: In Framingham Heart Study (FHS) participants (N = 2722, age 54 ± 9 years, 53% women), vibration-controlled transient elastography (VCTE) was performed between 2016-2019 to assess hepatic steatosis (continuous attenuation parameter [CAP]) and fibrosis (liver fibrosis measure [LSM]).

Pathways From Socioeconomic Factors to Major Cardiovascular Events Among Postmenopausal Veteran and Nonveteran Women: Findings From the Women's Health Initiative.

Background: Cardiovascular disease (CVD) remains a leading cause of death for women in the United States, with veterans being at potentially higher risk than their nonveteran counterparts due to accelerated aging and distinct biopsychosocial mechanisms. We examined pathways between selected indicators of socioeconomic status (SES) such as education, occupation, household income, and neighborhood SES and major CVD events through lifestyle and health characteristics among veteran and nonveteran postmenopausal women.

Methods And Results: A total of 121 286 study-eligible WHI (Women's Health Initiative) participants (3091 veterans and 118 195 nonveterans) were prospectively followed for an average of 17 years, during which 16 108 major CVD events were documented.

Mitochondrial Fitness Science Communication for Aging Adults: Prospective Formative Pilot Study.

Background: A key driver that leads to age-associated decline and chronic disease is mitochondrial dysfunction. Our previous work revealed strong community interest in the concept of mitochondrial fitness, which led to the development of a video-based science communication intervention to prompt behavior change in adults aged 50 years and older.

Objective: This study aimed to conduct formative and summative evaluations of MitoFit, an instructional, biologically based communication intervention aimed at improving physical activity in older adults aged 50 years and older.

PARTIAL OCCLUSION, LESS AKI: AN AORTA REGISTRY ANALYSIS OF PREBOA-PRO.

Background: Noncompressible torso hemorrhage remains a leading cause of potentially preventable deaths. Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) has emerged as an adjunct temporizing hemorrhage control. The complete occlusion strategy with the ER-REBOA catheter can cause distal ischemia when used for longer than 30 min.

Bilateral Cochlear Implants and Bimodal Hearing: A Comparison of Quality of Life.

Background:  Despite significant advances in the field of cochlear implants (CIs), there is no widely accepted criterion for when to counsel on bilateral CIs in adults. This is partly due to conflicting findings on the advantages of bilateral CIs versus bimodal hearing (i.e.

Cochlear Implantation With Sporadic Inner Ear Schwannomas: Outcomes in 106 Patients From an International Multi-Institutional Study.

Objective: To evaluate cochlear implant speech perception among patients with sporadic inner ear schwannoma who underwent ipsilateral implantation.

Study Design: Retrospective multi-institutional cohort study.

Setting: Eleven tertiary academic medical centers across Germany, Denmark, and the United States.

Density functional theory for fractional charge: Locality, size consistency, and exchange-correlation.

We show that the exact universal density functional of integer electronic charge leads to an extension to fractional charge in an asymptotic sense when it is applied to a system made of asymptotically separated densities. The extended functional is asymptotically local and is said to be i-local. The concept of i-locality is also applicable to nuclear external potentials, and a natural association exists between the localities of a density and a set of nuclei.
