Short term effectiveness of ustekinumab versus vedolizumab in Crohn's disease after failure of anti-TNF agents: An observational comparative study design with a Bayesian analysis.

Background: Crohn's disease (CD) is a debilitating gastrointestinal disease with complex etiology. Although effective, recipients of anti-tumor necrosis factor (TNF) agents may experience primary or secondary nonresponse, necessitating alternative treatments. This study is intended to compare the short-term effectiveness of ustekinumab and vedolizumab in treating CD after failure of multiple lines of anti-TNF therapy using real-world data.

Incidence Rate of Cardiovascular Events in Rheumatoid Arthritis: An Observational Cohort Study in Saudi Arabia.

Purpose: Rheumatoid arthritis (RA) doubles the morbidity of cardiovascular disease (CVD) and leads to a 50% increase in mortality compared to the general population. This study aims to estimate the CVD incidence among RA patients in Saudi Arabia (SA), vital for assessing CVD burdens within this group.

Patients And Methods: This retrospective study took place at two centers in the Eastern Province of SA, including all adult RA patients who visited the rheumatology clinic from 2016 to 2021 and were prescribed disease-modifying antirheumatic drugs (DMARDs).

Association between COVID-19 severity and tobacco smoking status: a retrospective cohort study using propensity score matching weights analysis.

Introduction: The COVID-19 pandemic continues to be a global threat to public health, with over 766 million confirmed cases and more than 6 million reported deaths. Patients with a smoking history are at a greater risk of severe respiratory complications and death due to COVID-19. This study investigated the association between smoking history and adverse clinical outcomes among COVID-19 patients admitted to a designated medical centre in Saudi Arabia.

Impact of common comorbidities on antimicrobial consumption and mortality amongst critically ill COVID-19 patients: A retrospective two center study in Saudi Arabia.

Objectives: To determine the association between common comorbidities, ICU mortality and antimicrobial consumption among critically ill COVID 19 patients in Saudi Arabia.

Methods: A retrospective observational study of patients admitted to the ICU from March 1st, 2020, through August 31st, 2021. We excluded patients who stayed <24 h in the ICU and with no confirmed COVID-19 PCR testing.

Effectiveness and Safety of Enoxaparin Versus Unfractionated Heparin as Thromboprophylaxis in Hospitalized COVID-19 Patients: Real-World Evidence.

Background: Coronavirus 2019 (COVID-19) patients are at risk of thrombosis. Literature that compares the effectiveness of enoxaparin to unfractionated heparin (UFH) in COVID-19 patients is scarce.

Objective: We aimed to evaluate the effectiveness and safety of enoxaparin compared with UFH when used at their standard/intermediate dosing in COVID-19 patients.

Combined Oral Contraceptives and Vascular Thrombosis: A Single-Center Experience.

Background Combined oral contraceptives (COCs) are frequently prescribed for contraception, to regulate ovulation and treat endometriosis, and to control menopausal symptoms. A major risk of hormonal contraceptives is vascular thrombosis. Methods A retrospective chart review of female patients with deep vein thrombosis (DVT), pulmonary embolism (PE), or other sites of thrombosis or emboli seen in the thrombosis clinic of the department of internal medicine at a tertiary care hospital in Saudi Arabia between March 2010 and February 2015 was performed to identify and characterize which women were taking COCs.

Tocilizumab effectiveness in mechanically ventilated COVID-19 patients (T-MVC-19 Study): a multicenter real-world evidence.

Background: This study aimed to evaluate the effectiveness of tocilizumab in mechanically ventilated patients with coronavirus disease 2019 (COVID-19).

Research Design And Methods: This retrospective multicenter study included adults (≥18 years) diagnosed with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by real-time polymerase chain reaction (RT-PCR) from nasopharyngeal swab, and requiring invasive mechanical ventilation during admission. Survival analyses with inverse propensity score treatment weighting (IPTW) and propensity score matching (PSM) were conducted.

Reducing Missed Medication Doses in Intensive Care Units: A Pharmacist-Led Intervention.

Objective: The objectives of this study were to investigate the frequency and reasons for missing doses and impact of a pharmacist-led intervention to reduce the missed doses in intensive care units.

Methods: This study was completed in two phases. In the first phase, a retrospective quality assurance audit was conducted to quantify the problem of missed doses from the pharmacist/nurse communication slip record.
