β-actin function in platelets and red blood cells can be performed by γ-actin and is therefore independent of actin isoform protein sequence.

Actin is an essential component of the cytoskeleton in every eukaryotic cell. Cytoplasmic β-and γ-actin are over 99% identical to each other at the protein level, but are encoded by different genes and play distinct roles in vivo. Blood cells, especially red blood cells (RBC), contain almost exclusively β-actin, and it has been generally assumed that this bias is dictated by unique suitability of β-actin for RBC cytoskeleton function due to its specific amino acid sequence.

Type 2 Diabetes Health Care Outcomes for Patients with Alcohol Use Disorder Starting Addiction Treatment.

Background: Alcohol use disorder (AUD) is common and may complicate type 2 diabetes (T2DM) management. Little research has examined diabetes outcomes for people with T2DM and AUD, including during the window when patients start specialty addiction treatment.

Objective: To examine diabetes-related health monitoring, clinical outcomes, and acute health care use among patients with T2DM and AUD newly accessing specialty addiction treatment.

Ecological and Reproductive Cycles Drive Henipavirus Seroprevalence in the African Straw-Coloured Fruit Bat ().

Bats are known to host zoonotic viruses, including henipaviruses that cause high fatality rates in humans (Nipah virus and Hendra virus). However, the determinants of zoonotic spillover are generally unknown, as the ecological and demographic drivers of viral circulation in bats are difficult to ascertain without longitudinal data. Here we analyse serological data collected from African straw-coloured fruit bats () in Ghana over the course of 2 years and across four sites, comprising three wild roosts and one captive colony.

Clinician perspectives on barriers and facilitators to the treatment of adolescent cannabis use: A qualitative study.

Introduction: Cannabis use among adolescents is prevalent, and clinicians who work with adolescents have unique insights about how to treat cannabis use in this population.

Methods: This qualitative study interviewed 32 clinicians from addiction medicine recovery services (AMRS), the emergency department (ED), mental health (MH), and pediatrics in an integrated healthcare system to understand their perspectives and experiences regarding barriers and facilitators to treating adolescent cannabis use. The analysis was developed using thematic analysis of interviews.

Performance of an envelope glycoprotein-based multiplex immunoassay for Ebola virus antibody detection in a cohort of Ebola virus disease survivors.

Serological surveillance in animal and human hosts can be a cost-effective strategy for orthoebolavirus detection, but is challenged by accurate estimates of seroprevalence, potential pauci-symptomatic disease presentation, and antigenic cross-reactivity. Here, we describe the use of an envelope glycoprotein (GP)-based multiplex microsphere immunoassay, consisting of nine filovirus GP antigens for the detection of anti-Ebola virus (EBOV) antibodies in a well-characterized cohort of Guinean Ebola virus disease (EVD) survivors and contacts from the 2013 - 2016 West African EVD outbreak. We examined sensitivity and specificity for the detection of anti-EBOV antibodies by GP expressed as recombinant trimeric ectodomains, yielding an assay performance of 95.

Association of Local Cannabis Policy and Retail Availability With Cannabis Use and Problematic Cannabis Use Among Adolescents in Northern California.

To examine whether local cannabis policies and retail availability are associated with cannabis use and problematic cannabis use (PCU) among adolescents in Northern California. The sample comprised adolescents aged 13 to 17 years screened for past-year cannabis use during well-child visits in 2021. Exposures included local bans on cannabis storefront retailers, policy protectiveness, and retail proximity and density.

Contextual factors associated with successful alcohol screening and brief intervention implementation and sustainment in adult primary care.

Introduction: Hazardous drinking is a public health problem affecting approximately 20 % of the U.S. primary care population.

Prospective changes in drinking during the COVID-19 pandemic among adults with unhealthy alcohol use.

Aims: This study examined differential changes in alcohol use during the COVID-19 pandemic among adults with unhealthy alcohol use.

Methods: Among 62 924 adults identified with unhealthy alcohol use in primary care prepandemic (1 January 2019 to 29 February 2020), changes in alcohol use during the pandemic (1 March 2020 to 30 June 2022) were examined using electronic health record data from Kaiser Permanente Northern California. Outcomes were changes in heavy drinking days in the past three months (HDDs) and overall consumption (drinks/week), including continuous and categorical measures.

Pediatric ACEs Screening and Referral: Facilitators, Barriers, and Opportunities for Improvement.

Despite well-documented associations between adverse childhood experiences (ACEs) and lifelong impairments in health and well-being, few studies have examined how to facilitate implementation of ACEs screening and referral programs in pediatric settings. We sought to identify facilitators and barriers related to screening for and addressing ACEs in a large integrated healthcare delivery system in Southern California. Using a developmental evaluation approach, we conducted twenty semi-structured interviews with pediatricians, nurses, social workers, and community referral organization staff.

Use of Codes for Adverse Social Determinants of Health Across Health Systems.

Objective: This study investigated codes for adverse social determinants of health (SDoH) across 12 U.S. health systems by using data from multiple health care encounter types for diverse patients covered by multiple payers.

Pilot Implementation of Guiando Buenas Decisiones, an Evidence-Based Parenting Program for Spanish-Speaking Families, in Pediatric Primary Care in a Large, U.S. Health System: A Qualitative Interview Study.

Adolescent substance use is a significant public health problem in the United States and Hispanic youth engage in substance use services at lower rates than other groups. For this under-served group, prevention services delivered in non-stigmatized, non-specialty care settings may increase access to the services. We describe findings from a feasibility pilot of the implementation of a virtual version of Guiando Buenas Decisiones (GBD), a universal, group-based substance use prevention program for parents.

Variation in completeness of coding external cause of injuries under ICD-10-CM.

Introduction: Information about causes of injury is key for injury prevention efforts. Historically, cause-of-injury coding in clinical practice has been incomplete due to the need for extra diagnosis codes in the International Classification of Diseases-Ninth Revision-Clinical Modification (ICD-9-CM) coding. The transition to ICD-10-CM and increased use of clinical support software for diagnosis coding is expected to improve completeness of cause-of-injury coding.

Racial and ethnic disparities in receipt of specialty treatment across risk profiles of adults with heavy alcohol use.

Background: Variation in specialty treatment utilization for alcohol use disorder (AUD) by patient subgroups is poorly understood. This study examined whether and how patient risk profiles predict receipt of specialty treatment and whether there are disparities by race and ethnicity.

Methods: This cohort study included 206,956 adults with heavy alcohol use (that which exceeded National Institute on Alcohol Abuse and Alcoholism guidelines) between June 1, 2013 and December 31, 2014, using electronic health record data from Kaiser Permanente Northern California.

Unhealthy Alcohol Use Among Adults With Depression or Anxiety: Changes During COVID-19 and Associations With Mental Health Treatment.

Objective: Individuals with unhealthy alcohol use and comorbid depression or anxiety may be vulnerable to alcohol use escalation in times of stress such as the COVID-19 pandemic. Among a cohort of individuals with pre-pandemic unhealthy drinking, we compared changes in alcohol use by whether people had a depression or anxiety diagnosis and examined whether mental health treatment was related to these changes.

Method: Using electronic health record data from Kaiser Permanente Northern California, we analyzed drinking changes during the pandemic (3/1/2020-6/30/2022) among adults identified in primary care with unhealthy alcohol use (exceeding daily/weekly recommended limits) pre-pandemic (1/1/2019-2/29/2020).

Clinician perspectives on adolescent cannabis-related beliefs and behaviors following recreational cannabis legalization.

Background: As more states legalize cannabis, studies are needed to understand the potential impacts of recreational cannabis legalization (RCL) on adolescents from the perspective of clinicians who care for them.

Methods: This qualitative study characterized clinician perspectives on whether cannabis legalization is associated with changes in adolescents' cannabis use beliefs, behaviors, and consequences. Semi-structured qualitative interviews were conducted with 32 clinicians in a large healthcare organization from 9/6/2022-12/21/2022.

Comparative Performance in the Detection of Four Coronavirus Genera from Human, Animal, and Environmental Specimens.

Emerging coronaviruses (CoVs) are understood to cause critical human and domestic animal diseases; the spillover from wildlife reservoirs can result in mild and severe respiratory illness in humans and domestic animals and can spread more readily in these naïve hosts. A low-cost CoV molecular method that can detect a variety of CoVs from humans, animals, and environmental specimens is an initial step to ensure the early identification of known and new viruses. We examine a collection of 50 human, 46 wastewater, 28 bat, and 17 avian archived specimens using 3 published pan-CoV PCR assays called Q-, W-, and X-CoV PCR, to compare the performance of each assay against four CoV genera.
