Objectives: Few studies describe contemporary alcohol withdrawal management in hospitalized settings or review current practices considering the guidelines by the American Society of Addiction Medicine (ASAM).

Methods: We conducted a retrospective cohort study of patients hospitalized with alcohol withdrawal on medical or surgical wards in 19 Veteran Health Administration (VHA) hospitals between October 1, 2018, and September 30, 2019. Demographic and comorbidity data were obtained from the Veteran Health Administration Corporate Data Warehouse.

Introduction: Concern about adverse effects from phenobarbital limits its use in treating alcohol withdrawal syndrome (AWS) on general medical wards. Benzodiazepines are the recommended treatment for inpatient management of AWS, yet a subset of patients have an inadequate response or experience complications of AWS despite treatment with benzodiazepines. Data supporting an alternative treatment are needed.

Background: The effect of initial COVID-19 pandemic-associated lockdowns on alcohol-related hospitalizations remains uncertain. This study compares alcohol-related hospitalizations at a US Department of Veterans Affairs (VA) system in Massachusetts before, during, and after the initial COVID-19 lockdown.

Methods: This study is an interrupted time-series analysis at the VA Boston Healthcare System.

Background: Hospitalizations related to the consequences of opioid use are rising. National guidelines directing in-hospital opioid use disorder (OUD) management do not exist. OUD treatment guidelines intended for other treatment settings could inform in-hospital OUD management.

Background: Patients with opioid use disorder (OUD) who are hospitalized for serious infections requiring prolonged intravenous antibiotics may face barriers to discharge, which could prolong hospital length of stay (LOS) and increase financial burden. We investigated differences in LOS, discharge disposition, and charges between hospitalizations for serious infections in patients with and without OUD.

Methods And Findings: We utilized the 2016 National Inpatient Sample-a nationally representative database of all discharges from US acute care hospitals.

The Clinical Learning Environment Review was created to evaluate quality improvement and patient safety (QIPS) beginning in 2013. Little guidance has been offered on implementing QIPS curricula for residency education. The aim was to provide a model QIPS residency curriculum from VA Boston Healthcare System (VABHS), wherein a chief resident in quality and patient safety (CRQS) participates in a national curriculum implementing skills and concepts locally.

Background: Pain is common among hospitalized patients. Inpatient prescribing of opioids is not without risk. Acute pain management guidelines could inform safe prescribing of opioids in the hospital and limit associated unintended consequences.

The United States is experiencing an epidemic of nonmedical opioid use and opioid overdose-related deaths. As a result, there have been a number of public health interventions aimed at addressing this epidemic. However, these interventions fail to address care of individuals with opioid use disorder during hospitalizations and, therefore, miss a key opportunity for intervention.

Serious infection is a recognized complication of intravenous drug abuse and a major cause of morbidity and mortality among intravenous drug users. Trends in rates of serious infection and the associated costs related to opioid abuse/dependence have not been previously investigated in the context of the US opioid use epidemic. Our study, using a nationally representative sample of US inpatient hospitalizations, showed that hospitalizations related to opioid abuse/dependence both with and without associated serious infection significantly increased from 2002 to 2012, respectively, from 301,707 to 520,275 and from 3,421 to 6,535.

Strain D7 of Saccharomyces cerevisiae was used to measure the induction by bleomycin (BLM) of mitotic recombination at the trp5 locus and point mutations at ilv1 in the presence and absence of acridine compounds. BLM is a potent mutagen and recombinagen in the D7 assay. The acridines vary, some being mutagenic or recombinagenic and others not.

The effects of amines on the induction of mitotic gene conversion by bleomycin (BLM) were studied at the trp5 locus in Saccharomyces cerevisiae strain D7. BLM induces double-strand breaks in DNA and is a potent recombinagen in this assay. The polyamine spermidine causes concentration-dependent protection against the genotoxicity of BLM, reducing the convertant frequency by over 90% under the most protective conditions.
