Atorvastatin Effect on COVID-19 Outcomes: A Propensity Score Matched Study on Hospitalized Patients.

Background: This study investigated the association of atorvastatin use on survival, need for intensive care unit (ICU) admission, and length of hospital stay (LOS) among COVID-19 inpatients.

Materials And Methods: A retrospective study was conducted between March 20th, 2020, and March 18th, 2021, on patients with confirmed COVID-19 admitted to three hospitals in Tehran, Iran. The unadjusted and adjusted effects of atorvastatin on COVID-19 prognosis were investigated.

Excess all-cause mortality and COVID-19 reported fatality in Iran (April 2013-September 2021): age and sex disaggregated time series analysis.

Objective: The actual impact of the pandemic on COVID-19 specific mortality is still unclear due to the variability in access to diagnostic tools. This study aimed to estimate the excess all-cause mortality in Iran until September 2021 based on the national death statistics.

Results: The autoregressive integrated moving average was used to predict seasonal all-cause death in Iran (R-squared = 0.

Contribution of Various Types of Transfusion to Acute and Delayed Intracerebral Hemorrhage Injury.

Intracerebral hemorrhage (ICH) is the second most prevalent type of stroke, after ischemic stroke, and has exceptionally high morbidity and mortality rates. After spontaneous ICH, one primary goal is to restrict hematoma expansion, and the second is to limit brain edema and secondary injury. Various types of transfusion therapies have been studied as treatment options to alleviate the adverse effects of ICH etiopathology.

The Effect of Intradermal Botulinum Toxin a injections on painful diabetic polyneuropathy.

Background And Aims: Botulinum toxin type A (BTX-A) have been recently administered to improve Diabetic neuropathies; however, the efficacy of this treatment for relieving pain in painful diabetic polyneuropathy (DPN) has not been studied yet. Herein, we investigated the efficacy of botulinum toxin A (BTX-A) on DPN.

Methods: This prospective, randomized, double-blind, controlled trial was performed in Imam Hossein Medical Center, pain clinic (Tehran, Iran).

Preemptive Oral Clonidine Provides Better Sedation Than Intravenous Midazolam in Brachial Plexus Nerve Blocks.

Background: Preemptive analgesia is the blocking of pain perception afferent pathways before noxious painful stimuli. Clonidine is an alpha agonist drug that is partially selective for α-2 adrenoreceptors. Clonidine is used as anti-anxiety medication and an, analgesic, and it prolongs the duration of the block in the brachial plexus block.

A comparison of prophylactic use of meperidine, meperidine plus dexamethasone, and ketamine plus midazolam for preventing of shivering during spinal anesthesia: a randomized, double-blind, placebo-controlled study.

Study Objectives: The aim of this study is to compare the efficacy of combination of meperidine and dexamethasone with that of placebo, meperidine alone, and the combination of ketamine and midazolam in preventing shivering during spinal anesthesia.

Design: This is a prospective, placebo-controlled study.

Setting: The setting is at an operating room of a university-based teaching hospital.

Priming with atracurium efficiently suppresses etomidate-induced myoclonus.

Introduction: Etomidate is a hypnotic drug widely used as an intravenous anesthetic induction agent. The incidence of etomidate-induced myoclonus has been reported as much as 50-80% after induction making it an undesirable drug for induction.

Objective: Our aim is to use a priming dose of atracurium to suppress etomidate-induced myoclonus during induction of anesthesia.

Implementation of statistical analysis in the clinical research of coeliac disease: use of probit and logit analysis.

Background: Coeliac disease (CD) is an autoimmune disorder of the small intestine that occurs in genetically predisposed people of all ages. The objective of this study is to investigate the relation between demographic and clinical factors with coeliac disease using probit and logit models.

Methods: During the period of January to December 2008, 396 patients were recruited for this study.

Assessment the relationship between reflux and body mass index with comparing different regression models.

Aim: The aim of this study was to determine whether there is relation between body mass index and symptoms of gastro-esophageal reflux disease in our community using Logit, Probit and Complementary log-log models.

Background: The most frequent statistical tool to address the relationship among a dichotomous response and other covariates is logistic regression. However logistic regression is familiar for researchers, some other models with similar results are favorable to assess such relationship like as Probit and Complementary log-log.

Prognostic factors in gastric cancer using log-normal censored regression model.

Background & Objective: Gastric cancer is one of the most common cancers in the world. It is rarely detected early, and the prognosis remains poor. Cox proportional hazard model is used to examine the relationship between survival and covariates.

Gastro-esophageal reflux symptoms and body mass index: no relation among the Iranian population.

An association between obesity and symptoms of gastro-esophageal reflux disease (GERD) has been frequently reported in western societies. A recent study indicated a consistent association between abdominal diameter and reflux-type symptoms in the white population, but no consistent association in the black population or Asians. It is unclear whether an association persists after adjusting for known risk factors of GERD among Asian populations.

Gastro-oesophageal reflux disease and irritable bowel syndrome: a significant association in an Iranian population.

Background: Gastro-oesophageal reflux disease and irritable bowel syndrome are common diseases, which may be related.

Aim: To assess the association between gastro-oesophageal reflux disease and irritable bowel syndrome in a country with high prevalence of Helicobacter pylori.

Methods: This study was designed as cross-sectional and population-based in Tehran province, Iran.

Subphrenic abscess and recurring focal lesions due to tuberculosis in a patient with IgA deficiency.

Subdiaphragmatic abscess has not yet been reported as a manifestation of tuberculosis. We report an IgA deficient patient with recurrent episodes of unusual extrapulmonary manifestations of tuberculosis including subdiaphragmatic abscesses and metacarpophalangeal osteomyelitis that was improved each time with antituberculosis drugs. There was not any resistance to the drugs used against mycobacterium despite repeated courses of antituberculosis regimens.
