Evaluation of the Effect of Risankizumab on the Pharmacokinetics of Cytochrome P450 Substrates in Patients with Moderately to Severely Active Ulcerative Colitis or Crohn's Disease.

Background And Objective: The objective of this study was to characterize the effects of risankizumab on the pharmacokinetics of cytochrome P450 (CYP) 1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A substrates in patients with moderately to severely active Crohn's disease (CD) or ulcerative colitis (UC) using a cocktail approach.

Methods: Patients with CD or UC (n = 20) received single doses of probe substrates for CYP1A2 (caffeine 100 mg), CYP2C9 (warfarin 10 mg), CYP2C19 (omeprazole 20 mg), CYP2D6 (metoprolol 50 mg), and CYP3A (midazolam 2 mg) before and after intravenous infusions of risankizumab 1800 mg once every 4 weeks for four doses. Serial blood samples were collected for determination of concentrations of the CYP probe drugs and metabolites with and without risankizumab.

Comparative Analysis of Inflammatory Bowel Disease Management: Hospital-based Versus Community-based Care.

Background: Inflammatory bowel disease (IBD) encompasses chronic gastrointestinal disorders characterized by recurrent inflammation. Achieving mucosal healing and preventing disease progression are primary treatment goals.

Objectives: This study aimed to compare disease characteristics, medication utilization, procedures performed, and hospitalizations between IBD patients treated in hospital and community settings using the Leumit Health Service database.

Duration-Dependent Risk of Hypoxemia in Colonoscopy Procedures.

: Colonoscopy is a critical diagnostic and therapeutic procedure in gastroenterology. However, it carries risks, including hypoxemia, which can impact patient safety. Understanding the factors that contribute to the incidence of severe hypoxemia, specifically the role of procedure duration, is essential for improving patient outcomes.

Assessing Generative Pretrained Transformers (GPT) in Clinical Decision-Making: Comparative Analysis of GPT-3.5 and GPT-4.

Background: Artificial intelligence, particularly chatbot systems, is becoming an instrumental tool in health care, aiding clinical decision-making and patient engagement.

Objective: This study aims to analyze the performance of ChatGPT-3.5 and ChatGPT-4 in addressing complex clinical and ethical dilemmas, and to illustrate their potential role in health care decision-making while comparing seniors' and residents' ratings, and specific question types.

Low cardiorespiratory fitness is associated with elevated intraocular pressure among apparently healthy adults.

Purpose: To evaluate the association of cardiorespiratory fitness with elevated intraocular pressure (IOP) in healthy adults.

Methods: In this cross-sectional study, we evaluated 17,990 asymptomatic self-referred adults free of diabetes or cardiovascular disease who were screened in a preventive healthcare setting. All subjects underwent measurement of IOP and completed a maximal exercise stress test according to the Bruce protocol.

Concomitant intravascular and extravascular obstructive shock: a case report of cardiac angiosarcoma presenting with pericardial tamponade.

Atraumatic pericardial tamponade and intracardiac masses are both recognized etiologies of acute obstructive shock. Pericardial tamponade, is a cardiovascular emergency commonly considered by emergency physicians and, as a result, evaluation for this process has been incorporated into standardized point of care ultrasound algorithms for assessing hypotension. Obstructive shock secondary to intracardiac tumors is an atypical clinical presentation, and although it is evaluated by the same ultrasound imaging modality, it is generally not considered or evaluated for in the emergency department setting.

Correction to: Atypical presentation of hemorrhagic shock in pregnancy: a case highlighting the developing field of emergency medicine in Israel.

The original article [1] contained a misspelling in first author, Baruch Berzon's name which has since been corrected.

Atypical presentation of hemorrhagic shock in pregnancy: a case highlighting the developing field of emergency medicine in Israel.

Background: Occult hemorrhagic shock secondary to uterine rupture represents a true obstetric emergency and can result in significant morbidity and mortality for both the patient and the fetus. Multiparity and prior cesarean sections are known risk factors. Typically, these patients present late in gestation, often secondary to the physiologic stresses on the uterus related to contractions.
