The investigation of the characteristics of inflammatory factors and cardiac enzymes in children with Covid-19 hospitalized with the initial manifestation of fever without other symptoms hazrat Ali-Asghar Hospital in Tehran in 2018-2019.

Introduction: The prevalence of asymptomatic fever among children is high and may be confused with fever caused by corona. The purpose of this study is to investigate the characteristics of inflammatory factors and cardiac enzymes in children with Covid-19 hospitalized with the initial manifestation of fever without other symptoms.

Methods: In this descriptive-analytical cross-sectional study, all 200 children with positive Covid-19 were hospitalized in Hazrat Ali-Asghar Hospital in Tehran between 2018 and 2019.

Study of readiness and performance of nurses in evaluating clinical care and processes of care and nursing.

Background: Clinical care and nursing skills are important issues that can influence the efficacy of treatment, the health of patients, and medical errors. The aim of this study was to investigate the readiness of medical staff in the field of effectiveness and evaluation of clinical care and nursing skills.

Materials And Methods: This descriptive, cross-sectional study was performed on 99 medical staff working in hospitals from August 2020 to December 2021.

Highly Stable Low-Cost Electrochemical Gas Sensor with an Alcohol-Tolerant N,S-Codoped Non-Precious Metal Catalyst Air Cathode.

The emerging applications of electrochemical gas sensors (EGSs) in Internet of Things-enabled smart city and personal health electronics bring out a new challenge for common EGSs, such as alcohol fuel cell sensors (AFCSs) to reduce the dependence on a pricy Pt catalyst. Here, for the first time, we propose a low-cost novel N,S-codoped metal catalyst (FeNSC) to accelerate oxygen reduction reaction (ORR) and replace the Pt catalyst in the cathode of an AFCS. The optimal FeNSC shows high ORR activity, stability, and alcohol tolerance.

Tracheostomy in Patients Who Need Mechanical Ventilation: Early or Late? Surgical or Percutaneous? A Prospective Study in Iran.

Tracheostomy can be performed surgically or by percutaneous (percutaneous dilatory tracheostomy, PDT) methods, and it may be used early or late. In a 3-month follow-up, all patients who underwent tracheostomy in Semnan in 2013 were evaluated for complications of tracheostomy considering the method used and the timing of operation. A total of 55 patients underwent tracheostomy (26 cases surgery, 29 cases PDT, 30 cases early, and 25 cases late based on 14 days reference).
