Inhaled corticosteroids' effect on COVID-19 patients: A systematic review and meta-analysis of randomized controlled trials.

Background: More than six million people died due to COVID-19, and 10-15% of infected individuals suffer from post-covid syndrome. Corticosteroids are widely used in the management of severe COVID-19 and post-acute COVID-19 symptoms. This study synthesizes current evidence of the effectiveness of inhaled corticosteroids (ICS) on mortality, hospital length-of-stay (LOS), and improvement of smell scores in patients with COVID-19.

Cost-effectiveness analysis of five anti-obesity medications from a US payer's perspective.

Background And Aims: To determine the cost-effectiveness of anti-obesity medications (AOM): tirzepatide, semaglutide, liraglutide, phentermine plus topiramate (PpT), and naltrexone plus bupropion (NpB).

Methods And Results: From a U.S.

Clinician Responses to a Clinical Decision Support Advisory for High Risk of Torsades de Pointes.

Background Torsade de pointes (TdP) is a potentially fatal cardiac arrhythmia that is often drug induced. Clinical decision support (CDS) may help minimize TdP risk by guiding decision making in patients at risk. CDS has been shown to decrease prescribing of high-risk medications in patients at risk of TdP, but alerts are often ignored.

Target receptor identification and subsequent treatment of resected brain tumors with encapsulated and engineered allogeneic stem cells.

Cellular therapies offer a promising therapeutic strategy for the highly malignant brain tumor, glioblastoma (GBM). However, their clinical translation is limited by the lack of effective target identification and stringent testing in pre-clinical models that replicate standard treatment in GBM patients. In this study, we show the detection of cell surface death receptor (DR) target on CD146-enriched circulating tumor cells (CTC) captured from the blood of mice bearing GBM and patients diagnosed with GBM.

Risk of tizanidine-induced adverse events after concomitant exposure to ciprofloxacin: A cohort study in the U.S.

Background: Tizanidine's potent muscle relaxant properties and short onset of action makes it desirable for pain management. However, concomitant use of tizanidine with ciprofloxacin, a strong inhibitor of the P450-CYP1A2 cytochrome metabolic pathway of tizanidine, can result in increased tizanidine plasma levels and associated adverse outcomes, particularly hypotension. The aim of this study was to assess the risk of hypotension with coadministration of tizanidine and ciprofloxacin.

A risk-stratified approach to venous thromboembolism prophylaxis with aspirin or warfarin following total hip and knee arthroplasty: A cohort study.

Introduction: Venous thromboembolism (VTE) and bleeding events following total knee and hip arthroplasty (TKA/THA) are associated with significant morbidity. Clinical guidelines recommend administration of pharmacologic VTE prophylaxis post-operatively, although controversy exists regarding optimal prophylactic strategies.

Methods: We performed a retrospective cohort study in patients who underwent elective TKA/TKA in an academic medical center.

Development and validation of an automated algorithm for identifying patients at higher risk for drug-induced acute kidney injury.

Purpose: Using information from institutional electronic health records, we aimed to develop dynamic predictive models to identify patients at high risk of acute kidney injury (AKI) among those who received a nephrotoxic medication during their hospital stay.

Methods: Candidate predictors were measured for each of the first 5 hospital days where a patient received a nephrotoxic medication (risk model days) to predict an AKI, using logistic regression with reduced backward variables elimination in 100 bootstrap samples. An AKI event was defined as an increase of serum creatinine ≥ 200% of a baseline SCr within 5 days after a risk model day.

Atrial Fibrosis by Late Gadolinium Enhancement Magnetic Resonance Imaging and Catheter Ablation of Atrial Fibrillation: 5-Year Follow-Up Data.

Background Late gadolinium enhancement magnetic resonance imaging is an effective tool for assessment of atrial fibrosis. The degree of left atrial fibrosis is a good predictor of atrial fibrillation ( AF ) ablation success at 1 year, but the association between left atrial fibrosis and long-term ablation success has not been studied. Methods and Results Late gadolinium enhancement magnetic resonance images of sufficient quality to quantify atrial fibrosis were obtained before the first AF ablation in 308 consecutive patients.

Increased dietary sodium enhances activation of neurons in the medullary cardiovascular pathway during acute sodium loading in the rat.

Increased sodium ingestion diminishes baroreflex-induced bradycardia in animals during acute sodium loading. These experiments studied effects of high sodium diet on activation of central nervous system sites associated with baroreflex activation and cardiovascular responses to hypernatremia during systemic sodium administration. Fos-like (Fos-Li) protein immunoreactivity was measured to estimate activation of neurons in the medullary baroreflex pathway (nucleus tractus solitarius (NTS), caudal ventrolateral medulla (CVLM), and rostral ventrolateral medulla (RVLM)), and in the hypothalamic paraventricular (PVN) and supraoptic nuclei (SON) in male Sprague-Dawley rats consuming standard chow and either tap water (TAP) or isotonic saline (ISO) for 2-3 weeks.

The early identification of anticonvulsant activity: role of the maximal electroshock and subcutaneous pentylenetetrazol seizure models.

A number of widely different animal seizure models have been employed in the search for new and novel anticonvulsant drugs useful for the treatment of human epilepsy. At present, no single laboratory test will, in itself, establish the presence or absence of anticonvulsant activity or fully predict the clinical potential of a test substance. Of the many available animal models, the maximal electroshock (MES) and subcutaneous pentylenetetrazol (scPTZ) tests still represent the most commonly employed models for the routine screening and identification of new anticonvulsant drugs.
