Impact of the COVID-19 pandemic on emergency department alcohol intoxication presentations and positive screens for problem drinking.

Our aim was to assess the changes in patients presenting with acute alcohol intoxications or positive screens for problem drinking during the COVID-19 pandemic compared to before the pandemic in a seven-hospital health system. A retrospective chart review of emergency department (ED) visits from seven hospitals in the Washington, DC/Baltimore, and MD area from January 2019 to June 2021 is provided. The health system utilizes a validated system for Screening, Brief Intervention, and Referral to Treatment (SBIRT) for ED patients. We evaluated trends in patients who had a positive SBIRT screen for problem drinking (AUDIT-C score ≥ 3 in women, 4 in men), alcohol misuse (≥5), and those presenting with acute alcohol intoxication before March 2020 and during the early COVID pandemic period. There were 510 648 patients who were screened, ranging from ages of 16 to 95 years during the study period. There was an overall increase in patients who screened positive for problem drinking, alcohol misuse, and acute intoxications. While there was an overall decrease in the total number of ED visits during the start of the pandemic, which later increased near prepandemic levels, alcohol-related presentations as a percentage of total visits increased during the early pandemic period. There was an overall decrease in ED visits during the COVID-19 pandemic study period; problem drinking and acute intoxication presentation held steady, leading to an overall increase in proportion compared to pre-COVID-19 levels. Future research should focus on lessons learned during this time and should navigate the postpandemic care of patients with AUD. There was an increase in the proportion of ED visits for alcohol intoxications and positive screens for problem drinking during the COVID-19 pandemic in our seven-hospital system.

Developing trends in the intestinal transplant waitlist.

The United Network for Organ Sharing database was examined for trends in the intestinal transplant (ITx) waitlist from 1993 to 2012, dividing into listings for isolated ITx versus liver-intestine transplant (L-ITx). Registrants added to the waitlist increased from 59/year in 1993 to 317/year in 2006, then declined to 124/year in 2012; Spline modeling showed a significant change in the trend in 2006, p < 0.001. The largest group of registrants, <1 year of age, determined the trend for the entire population; other pediatric age groups remained stable, adult registrants increased until 2012. The largest proportion of new registrants were for L-ITx, compared to isolated ITx; the change in the trend in 2006 for L-ITx was highly significant, p < 0.001, but not isolated ITx, p = 0.270. New registrants for L-ITx, <1 year of age, had the greatest increase and decrease. New registrants for isolated ITx remained constant in all pediatric age groups. Waitlist mortality increased to a peak around 2002, highest for L-ITx, in patients <1 year of age and adults. Deaths among all pediatric age groups awaiting L-ITx have decreased; adult L-ITx deaths have dropped less dramatically. Improved care of infants with intestinal failure has led to reduced referrals for L-ITx.

Statistical Optimization of Sustained Release Venlafaxine HCI Wax Matrix Tablet.

The purpose of this research was to prepare a sustained release drug delivery system of venlafaxine hydrochloride by using a wax matrix system. The effects of bees wax and carnauba wax on drug release profile was investigated. A 3(2) full factorial design was applied to systemically optimize the drug release profile. Amounts of carnauba wax (X(1)) and bees wax (X(2)) were selected as independent variables and release after 12 h and time required for 50% (t(50)) drug release were selected as dependent variables. A mathematical model was generated for each response parameter. Both waxes retarded release after 12 h and increases the t(50) but bees wax showed significant influence. The drug release pattern for all the formulation combinations was found to be approaching Peppas kinetic model. Suitable combination of two waxes provided fairly good regulated release profile. The response surfaces and contour plots for each response parameter are presented for further interpretation of the results. The optimum formulations were chosen and their predicted results found to be in close agreement with experimental findings.
