Utility of word embeddings from large language models in medical diagnosis.

Objective: This study evaluates the utility of word embeddings, generated by large language models (LLMs), for medical diagnosis by comparing the semantic proximity of symptoms to their eponymic disease embedding ("eponymic condition") and the mean of all symptom embeddings associated with a disease ("ensemble mean").

Materials And Methods: Symptom data for 5 diagnostically challenging pediatric diseases-CHARGE syndrome, Cowden disease, POEMS syndrome, Rheumatic fever, and Tuberous sclerosis-were collected from PubMed. Using the Ada-002 embedding model, disease names and symptoms were translated into vector representations in a high-dimensional space.

Differences in Phenotypes, Treatments, and Outcomes of ANCA-associated Vasculitis across Europe, Japan, and the United States in 2020.

Objectives: To clarify the differences in clinical phenotypes, therapeutic patterns, and outcomes of patients with granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) across geographic regions using a multinational cohort.

Methods: Data were collected from patients with newly diagnosed or relapsing GPA or MPA in Europe, Japan, and the United States (US) from January to July 2020. The composite outcome of kidney failure and/or death within 52 weeks after treatment was evaluated, and the hazard ratios across the regions were estimated using the Cox proportional hazard model.

Effect of a Narrative-Based Online Course Aimed at Reducing Stigma Toward Transgender Children and Adolescents: Longitudinal Observational Study.

Background: Stigma toward transgender children and adolescents negatively impacts their health and educational outcomes. Contact with members of stigmatized groups can dismantle stereotypes and reduce stigma by facilitating exposure to the unique cognitive and emotional perspectives of individuals within the group. Recent evidence suggests that video-based contact interventions can be as effective as face-to-face encounters, but challenges lie in protecting the identities of transgender youth, since many of them live in stealth.

Factors associated with asthma symptoms in Colombian subpopulations aged 1 to 17 and 18 to 59: Secondary analysis of the study "Prevalence of asthma and other allergic diseases in Colombia 2009-2010".

Objective: This study aimed to explore the association of multiple possible factors with asthma symptoms in two subpopulations, children, adolescents, and adults, in six cities in Colombia.

Semblans: Automated assembly and processing of RNA-Seq data.

Motivation: Recent advancements in parallel sequencing methods have precipitated a surge in publicly available short-read sequence data. This has encouraged the development of novel computational tools for the de novo assembly of transcriptomes from RNA-seq data. Despite the availability of these tools, performing an end-to-end transcriptome assembly remains a programmatically involved task necessitating familiarity with best practices.

Development and Validation of a Routine Electronic Health Record-Based Delirium Prediction Model for Surgical Patients Without Dementia: Retrospective Case-Control Study.

Background: Postoperative delirium (POD) is a common complication after major surgery and is associated with poor outcomes in older adults. Early identification of patients at high risk of POD can enable targeted prevention efforts. However, existing POD prediction models require inpatient data collected during the hospital stay, which delays predictions and limits scalability.

Bayesian Gene Set Benchmark Dose Estimation for "omic" responses.

Motivation: Estimating a toxic reference point using tools like the benchmark dose (BMD) is a critical step in setting policy to regulate pollution and ensure safe environments. Toxicity can be measured for different endpoints, including changes in gene expression and histopathology for various tissues, and is typically explored one gene or tissue at a time in a univariate setting that ignores correlation. In this work, we develop a multivariate estimation procedure to estimate the BMD for specified gene sets.

Applying Natural Language Processing Techniques to Map Trends in Insomnia Treatment Terms on the r/Insomnia Subreddit: Infodemiology Study.

Objective: The aim of this study is to summarize and chart trends of insomnia treatment terms on a digital insomnia message board.

A new pipeline SPICE identifies novel JUN-IKZF1 composite elements.

Transcription factor partners can cooperatively bind to DNA composite elements to augment gene transcription. Here, we report a novel protein-DNA binding screening pipeline, termed Spacing Preference Identification of Composite Elements (SPICE), that can systematically predict protein binding partners and DNA motif spacing preferences. Using SPICE, we successfully identified known composite elements, such as AP1-IRF composite elements (AICEs) and STAT5 tetramers, and also uncovered several novel binding partners, including JUN-IKZF1 composite elements.

Reducing Greenhouse Gas Emissions and Modifying Nitrous Oxide Delivery at Stanford: Observational, Pilot Intervention Study.

Background: Inhalational anesthetic agents are a major source of potent greenhouse gases in the medical sector, and reducing their emissions is a readily addressable goal. Nitrous oxide (NO) has a long environmental half-life relative to carbon dioxide combined with a low clinical potency, leading to relatively large amounts of NO being stored in cryogenic tanks and H cylinders for use, increasing the chance of pollution through leaks. Building on previous findings, Stanford Health Care's (SHC's) NO emissions were analyzed at 2 campuses and targeted for waste reduction as a precursor to system-wide reductions.

Use of mHealth Technology for Improving Exercise Adherence in Patients With Heart Failure: Systematic Review.

Background: The known and established benefits of exercise in patients with heart failure (HF) are often hampered by low exercise adherence. Mobile health (mHealth) technology provides opportunities to overcome barriers to exercise adherence in this population.

Objective: This systematic review builds on prior research to (1) describe study characteristics of mHealth interventions for exercise adherence in HF including details of sample demographics, sample sizes, exercise programs, and theoretical frameworks; (2) summarize types of mHealth technology used to improve exercise adherence in patients with HF; (3) highlight how the term "adherence" was defined and how it was measured across mHealth studies and adherence achieved; and (4) highlight the effect of age, sex, race, New York Heart Association (NYHA) functional classification, and HF etiology (systolic vs diastolic) on exercise adherence.

Common and uncommon risky drinking patterns in young adulthood uncovered by person-specific computational modeling.

Objective: Alcohol use offers social benefits for young adults, but also carries risk of significant negative consequences. Better understanding of processes driving alcohol use for those who experience negative consequences can prevent these harms. These at-risk young adults likely have drinking patterns in common and patterns unique to each individual.

Protective behavioral strategies and alcohol consequences following a group-based motivational intervention for young adults experiencing homelessness.

Objective: Young adults experiencing homelessness are at high risk for alcohol-related consequences, but protective behavioral strategies (PBS) have not been investigated as a harm reduction approach in this population. This study examines longitudinal associations between PBS and alcohol-related consequences following a group-based alcohol intervention.

Method: Data come from AWARE, a randomized controlled trial of a group-based motivational intervention to reduce substance use and risky sex compared to usual care.

Alcohol and emotion: Analyzing convergence between facially expressed and self-reported indices of emotion under alcohol intoxication.

Objective: Emotion measurement is central to capturing acute alcohol reinforcement and so to informing models of alcohol use disorder etiology. Yet our understanding of how alcohol impacts emotion as assessed across diverse response modalities remains incomplete. The present study leverages a social alcohol-administration paradigm to assess drinking-related emotions, aiming to elucidate impacts of intoxication on self-reported versus behaviorally expressed emotion.

Dispositional coping profiles moderate the links between racial discrimination and mental health in Black Americans.

Objectives: Racial discrimination is consistently linked to negative mental health outcomes. However, less is known about how unique patterns of coping in Black Americans experiencing high discrimination stress may moderate the association between discrimination and mental health. The present study uses person-centered methods to identify and describe latent profiles of coping in Black Americans, to understand how these coping profiles are linked to mental health, and to examine whether latent coping profiles moderate the links between discrimination and mental health.

A high-throughput platform for single-molecule tracking identifies drug interaction and cellular mechanisms.

The regulation of cell physiology depends largely upon interactions of functionally distinct proteins and cellular components. These interactions may be transient or long-lived, but often affect protein motion. Measurement of protein dynamics within a cellular environment, particularly while perturbing protein function with small molecules, may enable dissection of key interactions and facilitate drug discovery; however, current approaches are limited by throughput with respect to data acquisition and analysis.

Postpartum depressive symptoms and mother-infant dyadic reciprocity: The moderating role of partner support.

Maternal postpartum depressive (PPD) symptoms have the potential to negatively impact mother-infant interactions, particularly in populations experiencing contextual stress. We used a resilience perspective to examine maternal perceptions of partner support as a protective factor in the relation between PPD symptoms and mother-infant dyadic reciprocity. Low income, Mexican-origin women ( = 322; = 27.

The significance of mothers' neural responding to infant emotional cues for caregiving behaviors: The moderating role of infant temperamental distress.

We examined associations between mothers' ( = 137; 77.7% White/non-Hispanic) neural responding implicated in facial encoding (N170) and attention (P300) to infant emotional expressions and direct observations of their caregiving behaviors toward their 6-month-old infants. We also explored the moderating role of mother-reported and observer-rated infant temperamental distress.

Virtual Neonatal Resuscitation Curriculum for Emergency Medical Services (EMS) to Improve Out-of-Hospital Newborn Care.

Objectives: Out-of-hospital births are associated with a 2-to 11-fold increased risk of death compared to in-hospital births and are growing. Emergency Medical Services (EMS) clinicians have limited exposure to hospital birth emergencies, and there is no standardized prehospital neonatal resuscitation curriculum. Neonatal Resuscitation Program (NRP) guidelines are the standard of care for infants born in the United States but focuses on in-hospital births and is not easily applied to EMS.

A Brønsted acid-catalyzed enantioselective synthesis of ()-1,3-butadienyl-2-carbinols is developed. By employing a chiral phosphoric acid as the catalyst, a variety of 1,3-butadienyl-2-carbinols were obtained in good yields with excellent -selectivities and enantiopurities from α-alkyl-substituted homoallenyl boronates.

Regional Trends and Spatial Gradients of Total Column Methane over India, China, and USA─Implications for Emissions from Coal Mining and Oil/Gas Exploitation.

Observation-based verification of regional/national methane (CH) emission trends is crucial for transparent monitoring and mitigation strategy planning. Although surface observations track the global and sub-hemispheric emission trends well, their sparse spatial coverage limits our ability to assess regional trends. Dense satellite observations complement surface observations, offering a valuable means to validate emission trends, especially in regions where emissions changes are substantial but debated.

Rural Communities in the Deep South: Examining the Relationship Between Social Function and General Health Perceptions in Older Black Americans.

Background: Increased mortality in rural southern areas has persisted and worsened among older Black adults due to high prevalence of chronic conditions combined with limited healthcare access resulting from social and structural factors.

Objective: Our objective was to examine the relationship between general health perceptions, social functioning, mental health, and demographic characteristics among Black adults living in the rural south.

Methods: This cross-sectional study examined health perceptions in older Black Americans residing in four rural towns within Alabama (Clayton, Fort Deposit, Hobson City, and York).

Understanding the Role of Trust in Healthcare and Intentions to Pursue Live Donor Kidney Transplant Among African American End Stage Kidney Disease Patients.

African Americans (AAs) with end-stage kidney disease (ESKD) experience significant barriers to accessing living donor kidney transplantation (LDKT), largely due to individual and systemic factors, including a lack of trust in healthcare systems resulting from a legacy of and continued experiences with medical racism. This cross-sectional study analyzed survey data from 416 AA patients with ESKD undergoing transplant evaluation in 2019-2023 at two kidney transplant centers in the Southeast United States, examining whether trust (specifically trust in kidney doctors, hospitals, and healthcare) modifies the relationship between attitudes towards LDKT and behavioral intentions to discuss LDKT with family and friends. Multivariable analyses revealed significant interactions.

Children's executive functioning and health behaviors across pediatric life stages and ecological contexts.

Executive functioning (EF) has been linked to chronic disease risk in children. Health behaviors are thought to partially explain this association. The current cross-sectional study evaluated specific domains of EF and varied health behaviors in three pediatric life stages.
