Redefining the spliceosomal introns of the sexually transmitted parasite and its close relatives in columbid birds.

infects the urogenital tract of men and women and causes the sexually transmitted infection trichomoniasis. Since the publication of its draft genome in 2007, the genome has drawn attention for several reasons, including its unusually large size, massive expansion of gene families, and high repeat content. The fragmented nature of the draft assembly made it challenging to obtain accurate metrics of features, such as spliceosomal introns.

An Educational Intervention to Promote Central Nervous System-Active Deprescribing in Dementia: A Pilot Study.

Background: Central nervous system (CNS)-active polypharmacy (defined as concurrent exposure to three or more antidepressant, antipsychotic, antiseizure, benzodiazepine, opioid, or nonbenzodiazepine benzodiazepine receptor agonists) is associated with significant potential harms in persons living with dementia (PLWD).We conducted a pilot trial to assess a patient nudge intervention's implementation feasibility and preliminary effectiveness to prompt deprescribing conversations between PLWD experiencing CNS-active polypharmacy and their primary care clinicians ("clinicians").

Methods: We used the electronic health record to identify PLWD prescribed CNS-active polypharmacy in primary care clinics from two health systems.

Comparative genomics of the sexually transmitted parasite reveals relaxed and convergent evolution and genes involved in spillover from birds to humans.

is the causative agent of the venereal disease trichomoniasis which infects men and women globally and is associated with serious outcomes during pregnancy and cancers of the human reproductive tract. Trichomonads parasitize a range of hosts in addition to humans including birds, livestock, and domesticated animals. Recent genetic analysis of trichomonads recovered from columbid birds has provided evidence that these parasite species undergo frequent host-switching, and that a current epoch spillover event from columbids likely gave rise to in humans.

SID-2 is a conserved extracellular vesicle protein that is not associated with environmental RNAi in parasitic nematodes.

In the free-living nematode the transmembrane protein SID-2 imports double-stranded RNA into intestinal cells to trigger systemic RNA interference (RNAi), allowing organisms to sense and respond to environmental cues such as the presence of pathogens. This process, known as environmental RNAi, has not been observed in the most closely related parasites that are also within clade V. Previous sequence-based searches failed to identify orthologues in available clade V parasite genomes.

Clinician contributions to central nervous system-active polypharmacy among older adults with dementia in the United States.

Background: Exposure to central nervous system (CNS)-active polypharmacy-overlapping exposure to three or more CNS-active medications-is potentially harmful yet common among persons living with dementia (PLWD). The extent to which these medications are prescribed to community-dwelling PLWD by individual clinicians versus distributed across multiple prescribers is unclear.

Methods: We identified community-dwelling Medicare beneficiaries with a dementia diagnosis and Medicare Parts A, B, and D coverage for at least one month in 2019.

Study protocol for a sequential multiple assignment randomized trial to decrease alcohol use before and after surgery.

Background: High-risk alcohol consumption in the weeks before and after surgery poses significant risks for postoperative recovery. Despite this, elective surgical patients are rarely offered alcohol-focused education, interventions, or treatment. This paper describes the protocol of a research study designed to evaluate the effectiveness of brief, non-pharmacological, therapeutic approaches to reduce alcohol use before and after surgery.

Interpersonal discrimination and depressive symptoms among older Black and African American adults.

To examine the association between recent experiences of discrimination and depressive symptom presentation and severity among a U.S. sample of older Black and African American adults.

Acceptability and feasibility of a mobile behavioral economic health intervention to reduce alcohol use in adults in rural areas.

Background: At-risk alcohol use is associated with increased adverse health consequences, yet is undertreated in healthcare settings. People residing in rural areas need improved access to services; however, few interventions are designed to meet the needs of rural populations. Mobile interventions can provide feasible, low-cost, and scalable means for reaching this population and improving health, and behavioral economic approaches are promising.

Improving alcohol treatment engagement using integrated behavioral interventions in alcohol-associated liver disease: A randomized pilot trial.

Introduction: Alcohol cessation improves mortality in alcohol-associated liver disease (ALD), but few ALD patients will engage in treatment. We aimed to demonstrate the feasibility and acceptability of a mobile health intervention to increase alcohol use disorder (AUD) treatment among ALD patients.

Methods: We conducted a pilot randomized controlled trial (September 2020 to June 2022) at a single tertiary care center in adults with any stage of ALD, past 6-month drinking, and no past-month AUD treatment.

Alcohol Use and Mortality Among Older Couples in the United States: Evidence of Individual and Partner Effects.

Background And Objectives: Spouses with concordant (i.e., similar) drinking behaviors often report better quality marriages and are married longer compared with those who report discordant drinking behaviors.

Adaptive interventions for alcohol misuse and violent behaviors among adolescents and emerging adults in the emergency department: A sequential multiple assignment randomized controlled trial protocol.

Alcohol use and violent behaviors among youth are associated with morbidity and mortality. An emergency department (ED) visit provides an opportunity to initiate prevention efforts. Despite promising findings from our single session SafERteens brief intervention (BI), impact is limited by modest effect sizes, with data lacking on optimal boosters to enhance effects.

Peer- and web-based interventions for risky drinking among US National Guard members: Mission Strong randomized controlled trial.

Aims: To test separatel the efficacy of a web-based and a peer-based brief intervention (BI), compared with an expanded usual care control (EUC) group, among military reserve component members using alcohoI in a hazardous and harmful manner.

Design: In the randomized controlled trial, participants were assigned to: [1] web-based BI with web-based boosters (BI + web), [2] web-based BI with peer-based boosters (BI + peer) or [3] enhanced usual care (EUC).

Setting: Michigan, USA.

Preoperative alcohol interventions for elective surgical patients: Results from a randomized pilot trial.

Background: High-risk alcohol use is a common surgical risk factor. Stopping or reducing alcohol use in the weeks before and after surgery could improve surgical health and outcomes. The purpose of this study was to evaluate the feasibility and acceptability of 2 interventions that address high-risk alcohol use in the context of surgery.

Patterns of same-day alcohol and cannabis use in adolescents and young adults with risky alcohol use.

Same-day alcohol and cannabis use is relatively common in adolescents and young adults, constituting a higher-risk behavior relative to single-substance use. However, the association between quantity of alcohol and cannabis use on co-use days is understudied. We examined the association between the quantity of alcohol and same-day cannabis use with a multilevel regression analysis in a sample of youth (16-24 years old) with risky alcohol use.

Strategies Associated With Reducing Benzodiazepine Prescribing to Older Adults: A Mixed Methods Study.

Purpose: Unlike in many community-based settings, benzodiazepine (BZD) prescribing to older veterans has decreased. We sought to identify health care system strategies associated with greater facility-level reductions in BZD prescribing to older adults.

Methods: We completed an explanatory sequential mixed methods study of health care facilities in the Veterans Health Administration (N = 140).

A randomized controlled trial of social media interventions for risky drinking among adolescents and emerging adults.

Purpose: Alcohol use among adolescents and emerging adults is an important public health issue requiring prevention approaches. Herein, we describe outcomes from a randomized controlled trial testing the efficacy of group-based social media interventions targeting risky drinking among youth.

Procedures: Using social media advertisements to screen potential participants, we recruited 955 youth (ages 16-24) reporting recent risky drinking.

Extracellular vesicles from malaria-infected red blood cells: not all are secreted equal.

Extracellular vesicles (EVs) mediate the transfer of molecules between cells and play diverse roles in host-pathogen interactions. Malaria is an important disease caused by intracellular Plasmodium species that invade red blood cells and these red blood cells release EVs. The EVs from infected cells have diverse functions in the disease and an obstacle in understanding how they exert their functions is that multiple EV types exist.

Genomic diversity across the Rickettsia and 'Candidatus Megaira' genera and proposal of genus status for the Torix group.

Members of the bacterial genus Rickettsia were originally identified as causative agents of vector-borne diseases in mammals. However, many Rickettsia species are arthropod symbionts and close relatives of 'Candidatus Megaira', which are symbiotic associates of microeukaryotes. Here, we clarify the evolutionary relationships between these organisms by assembling 26 genomes of Rickettsia species from understudied groups, including the Torix group, and two genomes of 'Ca.

Alcohol Use and Blood Pressure Among Older Couples: The Moderating Role of Negative Marital Quality.

Objectives: Spouses often have concordant drinking behaviors and important influences on one another's cardiovascular health. However, little is known about the implications of dyadic drinking patterns for blood pressure, and the marital factors that confer risk or resilience. This article examined links between alcohol use and blood pressure within individuals and opposite-sex couples over time, and whether those links vary by negative marital quality among older adults.

High-intensity drinking among adolescent and emerging adult risky drinkers.

High-intensity drinking (HID; 8+ U.S. standard drinks for women, 10+ men) is initiated during adolescence/emerging adulthood, increasing risk for negative outcomes, including blackouts.

Predictors of Booster Engagement Following a Web-Based Brief Intervention for Alcohol Misuse Among National Guard Members: Secondary Analysis of a Randomized Controlled Trial.

Background: Alcohol misuse is a major health concern among military members. Reserve component members face unique barriers as they live off base with limited access to behavioral health services. Web and app-based brief interventions are a promising means to improve access to treatment for those who misuse alcohol, with the use of booster sessions to enhance effectiveness, solidify gains, and reinforce changes.
