Basic Science and Pathogenesis.

Background: Non-coding RNA species, such as microRNA (miRNA), regulate multiple biological and pathological processes by binding to target mRNAs and facilitating alteration of translation levels via complexes such as RNA-induced silencing complex (RISC). Disrupting this process could contribute to AD pathogenesis by fostering aggregation of hyperphosphorylated microtubule-associated protein tau and amyloid-β (Aβ) peptides, and neuroinflammation. Understanding how these pathological changes are regulated remains our research focus.

Basic Science and Pathogenesis.

Background: Published data have highlighted associations between Alzheimer's disease (AD) susceptibility loci and AD-related brain changes. The amyloid imaging to prevent AD (AMYPAD) consortium is a European collaboration consisting of several parent cohorts, four of which had raw genotype array data available. We sought to integrate and harmonise the genetic data, calculate AD polygenic risk scores (PRS), and investigate their association with global amyloid deposition.

Development of an implementation intervention to promote adoption of the COMFORT clinical practice guideline for peripartum pain management: a qualitative study.

Background: Pain management after childbirth is widely variable, increasing risk of untreated pain, opioid harms, and inequitable experiences of care. The Creating Optimal Pain Management FOR Tailoring Care (COMFORT) clinical practice guideline (CPG) seeks to promote evidence-based, equitable acute peripartum pain management in the United States. We aimed to identify contextual conditions (i.

A scoping review and consensus recommendations for emergency medical services buprenorphine (EMS-Bupe) programs.

Objectives: Emergency Medical Services (EMS) agencies are beginning to provide low-barrier access to treatment for opioid use disorder (OUD) through the development of EMS buprenorphine (EMS-Bupe) programs. However, evidence-based practices for these programs are lacking. Our aim was to review the current literature on EMS and emergency department (ED) based buprenorphine treatment programs to provide consensus recommendations on the EMS-Bupe program development.

How community connection, homophobia, and racism shape gene expression in sexual minority men with and without HIV.

Objective: Although sexual minority men experience substantial discrimination, in addition to increased risk for several serious mental and somatic health problems, the biological mechanisms underlying these effects are unclear. To address this issue, we examined how experiences of social safety (i.e.

Development of a rapid screener to elicit patient preferences for antiseizure medication discontinuation.

Objective: While guidelines encourage individualized discussions of the risks and benefits of antiseizure medication (ASM) withdrawal after a period of seizure-freedom, no formal methods exist for assessing patient preferences. We report the initial development of a rapid patient preferences screener.

Methods: We conducted a mixed-methods study of adults who were ≥1 year seizure-free and seen for epilepsy across three institutions.

Quantifying the Diagnostic Utility of Baseline Testing in Concussion Management: An Analysis of Collegiate Athletes From the NCAA-DoD CARE Consortium Dataset.

Background: Although preseason baseline testing is a commonly recommended part of the concussion management process, its "value-added" contribution to the diagnosis of acute concussion compared with normative reference values remains in question.

Purpose: This research aimed to evaluate the diagnostic benefits of baseline testing in acute concussion assessment compared with normative reference values and characterize the athletes who receive the most diagnostic utility from baseline testing.

Study Design: Cohort study (Diagnosis); Level of evidence, 2.

Effects of Nursing Home Changes in Antipsychotic Use on Outcomes Among Residents With Dementia.

Objectives: Little information exists on whether nationwide efforts to reduce antipsychotic use among nursing home (NH) residents with Alzheimer's disease and related dementias improved mortality and hospitalization outcomes for residents. Our objective was to examine the effect of NH decreases in antipsychotic use on outcomes for residents with Alzheimer's disease and related dementias.

Design: Observational nationwide study that emulated a series of cluster randomized trials.

Beliefs and attitudes about men's alcohol-related sexual harassment and aggression (BAMASHA): Development and initial validation of a new scale.

Background: Men's perpetration of sexual violence (SV) toward women in drinking venues is a pervasive yet understudied phenomenon with significant downstream consequences for women. Although men's negative attitudes and beliefs toward women play an important role in SV, current attitude measures are limited in that they do not focus on SV specific to drinking contexts, thereby precluding understandings of SV in this context. As such, we developed and evaluated a measure of beliefs and attitudes about men's alcohol-related sexual harassment and aggression (BAMASHA) toward women in drinking venues to better understand this ubiquitous problem.

The brain selectively allocates energy to functional brain networks under cognitive control.

Network energy has been conceptualized based on structural balance theory in the physics of complex networks. We utilized this framework to assess the energy of functional brain networks under cognitive control and to understand how energy is allocated across canonical functional networks during various cognitive control tasks. We extracted network energy from functional connectivity patterns of subjects who underwent fMRI scans during cognitive tasks involving working memory, inhibitory control, and cognitive flexibility, in addition to task-free scans.

Factors Associated with Pediatric Drowning-Associated Lung Injury.

Objective: To identify risk factors for clinically-important drowning-associated lung injury (ciDALI) in children.

Study Design: This was a cross-sectional study of children (0 through18 years) who presented to 32 pediatric emergency departments (EDs) from 2010 through 2017. We reviewed demographics, comorbidities, prehospital data, chest radiographs reports, and ED course from emergency medical services, medical, and fatality records.

ReBandit: Random Effects Based Online RL Algorithm for Reducing Cannabis Use.

The escalating prevalence of cannabis use, and associated cannabis-use disorder (CUD), poses a significant public health challenge globally. With a notably wide treatment gap, especially among emerging adults (EAs; ages 18-25), addressing cannabis use and CUD remains a pivotal objective within the 2030 United Nations Agenda for Sustainable Development Goals (SDG). In this work, we develop an online reinforcement learning (RL) algorithm called reBandit which will be utilized in a mobile health study to deliver personalized mobile health interventions aimed at reducing cannabis use among EAs.

Transgender and Gender Diverse Patients Are Diagnosed with Borderline Personality Disorder More Frequently Than Cisgender Patients Regardless of Personality Pathology.

Purpose: Borderline personality disorder (BPD) is a severe form of psychopathology associated with a host of negative outcomes. Some literature suggests elevated prevalence among transgender and gender diverse (TGD) samples. Elevated BPD prevalence among TGD populations could be due to factors other than BPD-specific psychopathology.

Assessing the impact of clerkships on the growth of clinical knowledge.

Purpose: This study quantified the impact of clinical clerkships on medical students' disciplinary knowledge using the Comprehensive Clinical Science Examination (CCSE) as a formative assessment tool.

Methods: This study involved 155 third-year medical students in the College of Human Medicine at Michigan State University who matriculated in 2016. Disciplinary scores on their individual Comprehensive Clinical Science Examination reports were extracted by digitizing the bar charts using image processing techniques.

A descriptive examination of rurality in the Environmental influences on Child Health Outcomes Cohort: Implications, illustrations, and future directions.

Purpose: The Environmental influences on Child Health Outcomes (ECHO) Cohort has enrolled over 60,000 children to examine how early environmental factors (broadly defined) are associated with key child health outcomes. The ECHO Cohort may be well-positioned to contribute to our understanding of rural environments and contexts, which has implications for rural health disparities research. The present study examined the outcome of child obesity to not only illustrate the suitability of ECHO Cohort data for these purposes but also determine how various definitions of rural and urban populations impact the presentation of findings and their interpretation.

Recent Advances in the Study of Conflict-Related Sexual Violence.

Purpose Of Review: Conflict-related sexual violence (CRSV) is a frequent but not ubiquitous part of warfare, affecting not only survivors but also their families and wider communities. This thematic review describes advances in research on CRSV, reviews new developments in the literature, and proposes recommendations for future study.

Recent Findings: An increasing number of studies consider how to address methodological and ethical research challenges, how understudied victim/survivor groups as well as families and communities are affected by CRSV, how survivor-centered justice mechanisms can be developed to reduce impunity, and how CRSV is perceived by different actors.

Love as a Commitment Device : Evidence from a Cross-Cultural Study across 90 Countries.

Given the ubiquitous nature of love, numerous theories have been proposed to explain its existence. One such theory refers to love as a commitment device, suggesting that romantic love evolved to foster commitment between partners and enhance their reproductive success. In the present study, we investigated this hypothesis using a large-scale sample of 86,310 individual responses collected across 90 countries.

Development and Validation of a Brief Form of the Anticipated Effects of Food Scale.

Identifying malleable influences on eating behaviours will advance our ability to improve physical and mental health. Food-related emotional expectancies are the anticipated positive and negative emotions from eating different foods and are theorised to affect eating behaviour, and to be amenable to change. The Anticipated Effects of Food Scale (AEFS) assesses food-related emotional expectancies using 62 one-word items; however, a shorter questionnaire would be useful in large and clinical studies.

Preliminary Evidence That Shared Genetic Influences Underlie Comorbidity Between Self-Reported Eating and Internalizing Disorders and Gastrointestinal Disease in Adult Women and Men.

Introduction: Accumulating research suggests both eating disorders (EDs) and internalizing disorders (e.g., anxiety, depression) are associated with gastrointestinal disease (e.

A neurodegenerative cellular stress response linked to dark microglia and toxic lipid secretion.

The brain's primary immune cells, microglia, are a leading causal cell type in Alzheimer's disease (AD). Yet, the mechanisms by which microglia can drive neurodegeneration remain unresolved. Here, we discover that a conserved stress signaling pathway, the integrated stress response (ISR), characterizes a microglia subset with neurodegenerative outcomes.

Preferences, Perceptions, and Environmental Considerations of Natural and Synthetic Psychedelic Substances: Findings from the Global Psychedelic Survey.

Although several studies have well described the characteristics of people who use psychedelics alongside their motivations and beliefs, little research has examined the preferences surrounding the source of psychedelic substances. In an anonymous online survey, we collected data from 6,379 consumers of 11 different psychedelic substances from 85 different countries, exploring their preferences and perceptions on natural and synthetic psychedelics. There was a strong preference of natural sources over synthetic alternatives for psilocybin (75%), DMT (56%), and mescaline (56%).

The effects of cannabinoid agonism on auditory discrimination.

Recent evidence suggests that cannabis can impair simple auditory processes, and these alterations might be due to cannabinoid agonism. The effect of cannabinoid agonism on relatively complex processes such as auditory discrimination is unknown. The goal of this study was to examine the impact of WIN 55,212-2, a CB1 receptor and CB2 receptor agonism, on auditory discrimination using a go/no-go task.
