Intermediate-Dose versus Standard-Dose Prophylactic Anticoagulation in Patients with COVID-19 Admitted to the Intensive Care Unit: 90-Day Results from the INSPIRATION Randomized Trial.

Background: Thrombotic complications are considered among the main extrapulmonary manifestations of coronavirus disease 2019 (COVID-19). The optimal type and duration of prophylactic antithrombotic therapy in these patients remain unknown.

Methods: This article reports the final (90-day) results of the Intermediate versus Standard-dose Prophylactic anticoagulation In cRitically-ill pATIents with COVID-19: An opeN label randomized controlled trial (INSPIRATION) study.

Effect of Intermediate-Dose vs Standard-Dose Prophylactic Anticoagulation on Thrombotic Events, Extracorporeal Membrane Oxygenation Treatment, or Mortality Among Patients With COVID-19 Admitted to the Intensive Care Unit: The INSPIRATION Randomized Clinical Trial.

Importance: Thrombotic events are commonly reported in critically ill patients with COVID-19. Limited data exist to guide the intensity of antithrombotic prophylaxis.

Objective: To evaluate the effects of intermediate-dose vs standard-dose prophylactic anticoagulation among patients with COVID-19 admitted to the intensive care unit (ICU).

SP-A and TLR4 localization in lung tissue of SM-exposed patients.

Introduction: Long-term pulmonary complications are one of the major long-term consequences of sulfur mustard (SM) exposure. Toll-like receptor 4 (TLR4) involves in the pathogenesis of several pulmonary disorders. Surfactant protein-A (SP-A) regulates LPS-induced TLR4 localization and activation responses.

Pulmonary function and methacholine challenge tests in patients with ulcerative colitis.

Background: Ulcerative colitis is an inflammatory chronic disease which is believed to be a multi organ condition. The prevalence of ulcerative colitis is reportedly increasing in Iran presenting with the same clinical characteristics as in developing countries. Pulmonary manifestations of ulcerative colitis are increasingly reported.

Logistic regression model for prediction of airway reversibility using peak expiratory flow.

Background: Using peak expiratory flow (PEF) as an alternative to spirometry parameters (FEV1 and FVC), for detection of airway reversibility in diseases with airflow limitation is challenging. We developed logistic regression (LR) model to discriminate bronchodilator responsiveness (BDR) and then compared the results of models with a performance of >18%, >20%, and >22% increase in ΔPEF% (PEF change relative to baseline), as a predictor for bronchodilator responsiveness (BDR).

Materials And Methods: PEF measurements of pre-bronchodilator, post-bronchodilator and ΔPEF% of 90 patients with asthma (44) and chronic obstructive pulmonary disease (46) were used as inputs of model and the output was presence or absence of the BDR.

Exercise-induced bronchospasm among students of Tehran University of Medical Sciences in 2004.

Exercise-induced bronchospasm (EIB) is a clinical syndrome that affects 8-20% of the general population and 11-50% of athletes. Although a variety of testing protocols for the diagnosis of EIB have been pursued, the optimal algorithm still is lacking. The aim of this study was to determine the prevalence of EIB among students of Tehran University of Medical Sciences and to find out whether self-reported symptoms are sufficient to establish the diagnosis of EIB.
