Groundwater releases CO to diverse global coastal ecosystems.

Coastal ecosystems play a major role in marine carbon budgets, but substantial uncertainties remain in the sources and fluxes of coastal carbon dioxide (CO). Here, we assess when, where, and how submarine groundwater discharge (SGD) releases CO to shallow coastal ecosystems. Time-series observations of dissolved CO and radon (Rn, a natural groundwater tracer) across 40 coastal systems from 14 countries revealed large SGD-derived CO fluxes.

Differentiation of Related Events in Hippocampus Supports Memory Reinstatement in Development.

Adults are capable of either differentiating or integrating similar events in memory based on which representations are optimal for a given situation. Yet how children represent related memories remains unknown. Here, children (7-10 years old) and adults formed memories for separate yet overlapping events.

Do Cultural Adaptations Matter? Comparing Caregiver Training in Different Language for Latino Caregivers of Autistic Children: A Telehealth-Based Evaluation.

Culturally and linguistically diverse (CLD) families of autistic children face unique challenges in accessing services that are appropriate for their cultures and languages. The purpose of the current study was to evaluate the impact of training language on caregiver skill acquisition. Using behavioral skills training (BST) through telehealth, three Latino caregivers whose first language is Spanish were taught to implement two different behavioral protocols with their autistic children.

Functional genotype classification groups distinguish disease severity in recessive dystrophic epidermolysis bullosa.

Recessive dystrophic epidermolysis bullosa (RDEB) is a genetic disorder due to pathogenic variants in the COL7A1 gene. In this study we determined the association between different categories of COL7A1 variants and clinical disease severity in 236 RDEB patients in North America. Published reports or in-silico predictions were used to assess the impact of pathogenic variants in COL7A1 on type VII collagen (C7) protein function.

Unequal Effects of the Lockdown on Mental Health in Shanghai: The Moderating and Mediating Role of Neighborhood Environment and Online Social Connections.

The COVID-19 pandemic profoundly impacted population mental health worldwide. Few studies examined how the neighborhood environment and online social connections might influence the social gradient in mental health during the pandemic lockdown. We aim to examine the moderating and mediating role of neighborhood environment and online social connections in the association between socioeconomic status (SES) and mental health outcomes.

The trait-specific timing of accelerated genomic change in the human lineage.

Humans exhibit distinct characteristics compared to our primate and ancient hominin ancestors. To investigate genomic bursts in the evolution of these traits, we use two complementary approaches to examine enrichment among genome-wide association study loci spanning diseases and AI-based image-derived brain, heart, and skeletal tissue phenotypes with genomic regions reflecting four evolutionary divergence points. These regions cover epigenetic differences among humans and rhesus macaques, human accelerated regions (HARs), ancient selective sweeps, and Neanderthal-introgressed alleles.

Changes in Emergency Department Practices After Implementation of a Standardized Heavy Menstrual Bleeding Guideline.

Objective: The aim of the study is to assess the effect of an emergency department (ED) standardized clinical guideline for adolescent heavy menstrual bleeding on the rate of return ED visits and ED provider history-taking and management of this condition.

Methods: This was a retrospective cohort study. Patients less than 18 years old presenting to a single academic children's hospital ED between 2010 and 2020 with a chief complaint of heavy menstrual bleeding were included.

Surgical Site Infection After Sacral Neuromodulation: Impact of Postoperative Antibiotics.

Importance: There are limited data to guide practices to reduce surgical site infections following sacral neuromodulation; however, many surgeons prescribe prophylactic postoperative antibiotics after device implantation.

Objective: The aim of the study was to compare the proportion of patients with sacral neuromodulation device-associated surgical site infections after use of prophylactic postoperative antibiotics versus none.

Study Design: This was a multicenter retrospective cohort study of patients undergoing sacral neuromodulation device implantation at 11 institutions from January 2014 to December 2023, comparing outcomes in patients who did versus did not receive prophylactic postoperative antibiotic treatment.

Nonapoptotic role of EGL-1 in exopher production and neuronal health in .

While traditionally studied for their proapoptotic functions in activating the caspase, research suggests BH3-only proteins also have other roles such as mitochondrial dynamics regulation. Here, we find that EGL-1, the BH3-only protein in , promotes the cell-autonomous production of exophers in adult neurons. Exophers are large, micron-scale vesicles that are ejected from the cell and contain cellular components such as mitochondria.

A dataset and benchmark for hospital course summarization with adapted large language models.

Objective: Brief hospital course (BHC) summaries are clinical documents that summarize a patient's hospital stay. While large language models (LLMs) depict remarkable capabilities in automating real-world tasks, their capabilities for healthcare applications such as synthesizing BHCs from clinical notes have not been shown. We introduce a novel preprocessed dataset, the MIMIC-IV-BHC, encapsulating clinical note and BHC pairs to adapt LLMs for BHC synthesis.

Utilization of Palliative Care in Cardiogenic Shock Patients: A Retrospective Analysis of the National Inpatient Sample Database, 2020.

Cardiogenic shock (CS) is one of the leading causes of death in patients with myocardial infarction, myocarditis, and congestive heart failure. The utilization patterns of specialist palliative care (PC) consultation in these patients are currently unknown. To determine the utilization of PC in patients with CS and the overall comorbidities of that population.

Differential impacts of ribosomal protein haploinsufficiency on mitochondrial function.

The interplay between ribosomal protein (RP) composition and mitochondrial function is essential for energy homeostasis. Balanced RP production optimizes protein synthesis while minimizing energy costs, but its impact on mitochondrial functionality remains unclear. Here, we investigated haploinsufficiency for RP genes (rps-10, rpl-5, rpl-33, and rps-23) in Caenorhabditis elegans and corresponding reductions in human lymphoblast cells.

Brainstem Volume and White Matter Characteristics Associated with Cognitive Performance in Healthy Middle‐aged Adults.

Background: Traditionally linked to essential physiological functions, the brainstem is now acknowledged for its role in cognition and dementia. Abnormal tau protein accumulation starts in the brainstem. Late life brainstem volume at baseline also predicts later Alzheimer's Disease conversion.

Debunking the Myth of Excitatory and Inhibitory Repetitive Transcranial Magnetic Stimulation in Cognitive Neuroscience Research.

Repetitive TMS (rTMS) is a powerful neuroscientific tool with the potential to noninvasively identify brain-behavior relationships in humans. Early work suggested that certain rTMS protocols (e.g.

Using image‐text similarity scores from picture descriptions for differentiating the logopenic variant of progressive aphasia from amnestic Alzheimer’s dementia.

Background: Primary progressive aphasia (PPA) is a language‐led dementia associated with underlying Alzheimer’s disease (AD) or frontotemporal lobar degeneration pathology. As part of the Alzheimer’s spectrum, logopenic (lv) PPA may be particularly difficult to distinguish from amnestic AD, due to overlapping clinical features. Analysis of linguistic and acoustic variables derived from connected speech has shown promise as a diagnostic tool for differentiating dementia subtypes.

Education and Midlife Cognitive Functioning: Evidence from the High School and Beyond Cohort.

Background: Education is associated with cognitive functioning and risk of Alzheimer’s Disease and related dementias (ADRD). However, researchers rarely consider anything about education other than highest degree completion. Do schools’ social and academic contexts and students’ other (non‐attainment) schooling outcomes independently predict cognitive outcomes? If so, this opens the possibility of manipulating educational policies and practices to improve long term cognitive well‐being.

Beyond Credentials: Understanding Educational Gradients in Cognitive Function at Midlife.

Background: A substantial body of research points to the persistence of educational credential gradients in cognitive function across the life course, from early adulthood through old age. Fewer studies have considered the roles of and early in the life course in shaping (1) educational credential gradients or (2) variation in cognitive function among those with the same credentials. As a result, researchers underestimate the contribution of education writ large to variation in cognitive performance later in life.

Midlife Periodontal Disease and Cognitive Functioning: Evidence from High School and Beyond.

Background: Periodontal disease is a prevalent, preventable, and highly treatable oral infection that is (1) stratified by sociodemographic, educational, and spatial factors and (2) is believed to impact cognitive impairment and ADRD risk. However, there is very little information from community‐based, population‐representative, longitudinal studies about the association between periodontal disease and midlife cognitive functioning net of early life confounders.

Method: We use data from the U.

Cognition Four Decades After High School: Does School Context Matter for Cognitive Disparities at Midlife?

Background: Structural racism shapes educational quality by perpetuating unequal access to school resources, creating disproportionate exposure to disciplinary actions, and limiting access to advanced courses among racially minoritized children. School quality is linked to later life ADRD risk, but the benefit may vary across groups. We asked 1) whether the same high school social contexts and academic resources predict midlife cognitive functioning across race, ethnicity, and gender, and 2) how much could disparities in midlife cognitive function be narrowed if everyone had equal access to high quality high schools?

Method: Data was from the nationally representative High School and Beyond cohort, which prospectively followed 12,530 Americans from high school through age ∼60 and administered telephone‐ and web‐based measures of memory, language, and attention in 2021‐22.

Cohort and Gender Differences in Stability Over Five Years Among Mexican-Origin Caregivers to Older Adults Living With Cognitive Impairment.

The current study examines cohort (i.e., Generation X, Baby Boomers, and Silent Generation) and gender differences in the stability of Mexican-origin family caregivers over time.

Intergenerational Relationships and Family Support: Implications for Health and Wellbeing.

This review summarizes research projects supported by the National Institute on Aging (NIA) that have contributed scholarship on intergenerational relationships and support provided to older adults that frequently precedes, and is often complementary to, intensive caregiving. We review NIA-supported projects that have almost exclusively focused on intergenerational relationships and involved primary data collections, and others making use of omnibus aging and family studies that have allowed a variety of investigations on this topic. Where the former set of studies has generated deeply phenotypic analyses-comprehensive fine-grained analyses of relational data in specialized samples-the latter set has focused on analyses of secondary data, often from national samples which include information on intergenerational relationships.

Doxycycline Versus Vancomycin for the Treatment of Methicillin-Resistant Acute Pulmonary Exacerbations in People With Cystic Fibrosis.

Background: Among people with cystic fibrosis (PwCF), methicillin-resistant (MRSA)-associated acute pulmonary exacerbations (APEs) have been increasing in prevalence and can cause rapid declines in lung function and increased mortality. Fortunately, since 2019, incidence has started to decline.

Objective: The purpose of this study was to evaluate if doxycycline has comparable efficacy to vancomycin for the treatment of APEs in PwCF.
