Occurrence of Stigmatizing Documentation Among Hospital Medicine Encounters With Opioid-Related Diagnosis Codes: Cohort Study.

Background: Physician use of stigmatizing language in the clinical documentation of hospitalized adults with opioid use is common. However, patient factors associated with stigmatizing language in this setting remain poorly characterized.

Objective: This study aimed to determine whether specific demographic factors and clinical outcomes are associated with the presence of stigmatizing language by physicians in the clinical documentation of encounters with opioid-related ICD-10 (International Statistical Classification of Diseases, Tenth Revision) codes.

Toxicant Exposures and Health Symptoms in Military Pesticide Applicators From the 1991 Gulf War.

Objective: The chronic impact of acetylcholinesterase inhibitors and other toxicants on Gulf War (GW) veterans' health symptoms is unclear.

Methods: Building on reports of adverse neuropsychological outcomes in GW pesticide applicators exposed to pesticides and pyridostigmine bromide, we now report on health symptoms in this group.

Results: In adjusted analyses, applicators with high exposures/impact to pesticides reported significantly more symptoms (18/34 symptoms) than applicators with lower exposures/impact and were more likely to meet modified Kansas and CDC Gulf War Illness criteria.

Regulators of rDNA array morphology in fission yeast.

Nucleolar morphology is a well-established indicator of ribosome biogenesis activity that has served as the foundation of many screens investigating ribosome production. Missing from this field of study is a broad-scale investigation of the regulation of ribosomal DNA morphology, despite the essential role of rRNA gene transcription in modulating ribosome output. We hypothesized that the morphology of rDNA arrays reflects ribosome biogenesis activity.

Multi-task transfer learning for the prediction of entity modifiers in clinical text: application to opioid use disorder case detection.

Background: The semantics of entities extracted from a clinical text can be dramatically altered by modifiers, including entity negation, uncertainty, conditionality, severity, and subject. Existing models for determining modifiers of clinical entities involve regular expression or features weights that are trained independently for each modifier.

Methods: We develop and evaluate a multi-task transformer architecture design where modifiers are learned and predicted jointly using the publicly available SemEval 2015 Task 14 corpus and a new Opioid Use Disorder (OUD) data set that contains modifiers shared with SemEval as well as novel modifiers specific for OUD.

Community-Based Services for Hospitalized Patients With Serious Injection-Related Infections in Alabama: A Brief Report.

Injection-related infections continue to rise, particularly in the South. People who inject drugs are increasingly utilizing hospital services for serious injection-related infections but may be discharged to areas without harm reduction services. We explored the availability and travel time to services for HIV and substance use in Alabama.

National HIV and HCV Screening Rates for Hospitalized People who Use Drugs Are Suboptimal and Heterogeneous Across 11 US Hospitals.

Background: To end the HIV and hepatitis C virus (HCV) epidemics, people who use drugs (PWUD) need more opportunities for testing. While inpatient hospitalizations are an essential opportunity to test people who use drugs (PWUD) for HIV and HCV, there is limited research on rates of inpatient testing for HIV and HCV among PWUD.

Methods: Eleven hospital sites were included in the study.

Hospitalization is a missed opportunity for HIV screening, pre-exposure prophylaxis, and treatment.

Background: Hospitalization is a "reachable moment" for people who inject drugs (PWID), but preventive care including HIV testing, prevention and treatment is rarely offered within inpatient settings.

Methods: We conducted a multisite, retrospective cohort study of patients with opioid use disorder with infectious complications of injection drug use hospitalized between 1/1/2018-12/31/2018. We evaluated HIV care continuum outcomes using descriptive statistics and hypothesis tests for intergroup differences.

Xylazine co-occurrence with illicit fentanyl is a growing threat in the Deep South: a retrospective study of decedent data.

Background: Xylazine is a dangerous veterinary sedative found mainly in illicit fentanyl in the Northeast and Midwest. Its role in the Deep South overdose crisis is not well-characterized.

Methods: We conducted a retrospective review of autopsy data in Jefferson County, Alabama to identify trends in xylazine prevalence among people who fatally overdosed from June 2019 through June 2023.

Blood culture identification (BCID) performance in polymicrobial bacteremia.

The rapid multiplex PCR (rmPCR)-based FilmArray® blood culture identification (BCID) assay reduces time from positive blood culture to organism identification. Polymicrobial bacteremia (PMB) is a known area of reduced diagnostic fidelity for BCID and remains incompletely characterized. All cases of clinically confirmed PMB at a large academic single center from a 23-month period were evaluated in a retrospective cohort analysis.

Combined PD-1, BRAF and MEK inhibition in BRAF colorectal cancer: a phase 2 trial.

While BRAF inhibitor combinations with EGFR and/or MEK inhibitors have improved clinical efficacy in BRAF colorectal cancer (CRC), response rates remain low and lack durability. Preclinical data suggest that BRAF/MAPK pathway inhibition may augment the tumor immune response. We performed a proof-of-concept single-arm phase 2 clinical trial of combined PD-1, BRAF and MEK inhibition with sparatlizumab (PDR001), dabrafenib and trametinib in 37 patients with BRAF CRC.

Desmosomes: emerging pathways and non-canonical functions in cardiac arrhythmias and disease.

Desmosomes are critical adhesion structures in cardiomyocytes, with mutation/loss linked to the heritable cardiac disease, arrhythmogenic right ventricular cardiomyopathy (ARVC). Early studies revealed the ability of desmosomal protein loss to trigger ARVC disease features including structural remodeling, arrhythmias, and inflammation; however, the precise mechanisms contributing to diverse disease presentations are not fully understood. Recent mechanistic studies demonstrated the protein degradation component CSN6 is a resident cardiac desmosomal protein which selectively restricts cardiomyocyte desmosomal degradation and disease.

Desmosomal COP9 regulates proteome degradation in arrhythmogenic right ventricular dysplasia/cardiomyopathy.

Dysregulated protein degradative pathways are increasingly recognized as mediators of human disease. This mechanism may have particular relevance to desmosomal proteins that play critical structural roles in both tissue architecture and cell-cell communication, as destabilization/breakdown of the desmosomal proteome is a hallmark of genetic-based desmosomal-targeted diseases, such as the cardiac disease arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C). However, no information exists on whether there are resident proteins that regulate desmosomal proteome homeostasis.

Prenatal exposure to bisphenols affects pregnancy outcomes and offspring development in rats.

The objective of this study was to evaluate the effects of gestational exposure to low doses of bisphenol A (BPA), bisphenol S (BPS), and bisphenol F (BPF) on pregnancy outcomes and offspring development. Pregnant Sprague-Dawley rats were orally dosed with vehicle, 5 μg/kg body weight (BW)/day of BPA, BPS and BPF, or 1 μg/kg BW/day of BPF on gestational days 6-21. Pregnancy and gestational outcomes, including number of abortions and stillbirths, were monitored.

The role of gene dosage in budding yeast centrosome scaling and spontaneous diploidization.

Ploidy is the number of whole sets of chromosomes in a species. Ploidy is typically a stable cellular feature that is critical for survival. Polyploidization is a route recognized to increase gene dosage, improve fitness under stressful conditions and promote evolutionary diversity.

High-Throughput Identification of Nuclear Envelope Protein Interactions in Using an Arrayed Membrane Yeast-Two Hybrid Library.

The nuclear envelope (NE) contains a specialized set of integral membrane proteins that maintain nuclear shape and integrity and influence chromatin organization and gene expression. Advances in proteomics techniques and studies in model organisms have identified hundreds of proteins that localize to the NE. However, the function of many of these proteins at the NE remains unclear, in part due to a lack of understanding of the interactions that these proteins participate in at the NE membrane.

How to Start an Enhanced Recovery After Surgery Cardiac Program.

In this review the authors introduce a practical approach to guide the initiation of an enhanced recovery after surgery (ERAS) cardiac surgery program. The first step in implementation is organizing a dedicated multidisciplinary ERAS cardiac team composed of representatives from nursing, surgery, anesthesiology, and other relevant allied health groups. Identifying a program coordinator or navigator who will have responsibilities for developing and implementing educational initiatives, troubleshooting, monitoring progress and setbacks, and data collection is also vital for success.

Translation of small downstream ORFs enhances translation of canonical main open reading frames.

In addition to canonical open reading frames (ORFs), thousands of translated small ORFs (containing less than 100 codons) have been identified in untranslated mRNA regions (UTRs) across eukaryotes. Small ORFs in 5' UTRs (upstream (u)ORFs) often repress translation of the canonical ORF within the same mRNA. However, the function of translated small ORFs in the 3' UTRs (downstream (d)ORFs) is unknown.

One-year results from the first US-based enhanced recovery after cardiac surgery (ERAS Cardiac) program.

Objective: Our enhanced recovery after cardiac surgery (ERAS Cardiac) program is an evidence-based interdisciplinary process, which has not previously been systematically applied to cardiac surgery in the United States.

Methods: The Knowledge-to-Action Framework synthesized evidence-based enhanced recovery interventions and implementation of a designated ERAS Cardiac program. Standardized processes included (1) preoperative patient education, (2) carbohydrate loading 2 hours before general anesthesia, (3) multimodal opioid-sparing analgesia, (4) goal-directed perioperative insulin infusion, and (5) a rigorous bowel regimen.
