Discrete event simulation model of an acute stroke treatment process at a comprehensive stroke center: Determining the ideal improvement strategies for reducing treatment times.

Background: Fast treatment is crucial for ischemic stroke patients; the probability of good patient outcomes increases with faster treatment. Treatment times can be improved by making changes to the treatment process. However, it is challenging to identify the benefits of changes prior to implementation.

Anti-invasion activities of heat-killed lactic acid bacteria isolates against serovar Typhimurium.

Background And Objectives: The most common cause of severe foodborne salmonellosis is Typhimurium. Its interaction with intestinal epithelial cells is little known. Lactic acid bacteria (LAB) were recognized as a prominent probiotic gastrointestinal microbiota of humans and animals that confer health-promoting and protective effects.

Nasal absorption of oxycodone predicted using a novel computational fluid dynamics-physiologically based pharmacokinetic model.

Oxycodone hydrochloride (HCl) extended release (ER) tablet is an abuse-deterrent formulation that uses a physical barrier to make it more difficult to crush tablets prior to abuse via various routes. A previously conducted in vivo pharmacokinetics (PK) study showed that particle size exhibited significant effects on PK. Here, a computational modeling study using a novel combined computational fluid dynamics and physiologically based PK model was applied to better understand the mechanisms that produce differences in PK according to particle size and formulation type for nasally insufflated oxycodone HCl immediate release (IR) and ER tablets.

Turbulence in the system: Higher rates of left-without-being-seen emergency department visits and associations with increased risks of adverse patient outcomes since 2020.

Objective: To examine risks of severe adverse patient outcomes shortly after a left-without-being-seen emergency department (LWBS ED) visit since 2020.

Methods: In this retrospective study using linked administrative data, we examined temporal trends in monthly rates of ED and LWBS visits for adults in Ontario, Canada, 2014‒2023. In patient-level analyses restricted to the first eligible LWBS ED visit, we used modified Poisson regression to compare the composite outcome of 7-day all-cause mortality or hospitalization following a LWBS ED visit for April 1, 2022‒March 31, 2023 (recent period) to April 1, 2014‒March 31, 2020 (baseline period), adjusted for age, sex, and Charlson comorbidity index.

Hodgkin lymphoma in pre-existing thymoma: a case report.

Introduction: Thymus is a primary lymphoid organ which has an important role in humoral and cellular immunity. It can be a site for various neoplasms including thymomas.

Case Presentation: The authors report a case of a 55-year-old patient presenting with weight loss, night sweats and sensation of heat.
