Evaluation of the effect of favipiravir on patients with COVID-19.

Background: The novel coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) started in December 2019 in Wuhan, China. No specific drug has been accepted for COVID-19 treatment up to now. Favipiravir as an antiviral drug affects RNA viruses like influenza and Ebola. Accordingly, the aim of this study is the evaluation of favipiravir's effect on COVID-19 outcomes. Method: This is a randomized controlled study including 97 patients with COVID-19 randomly allocated into favipiravir or control groups. The primary outcomes were improvement of clinical manifestations and atrial oxygen saturation (SpO2), and the secondary outcome was the length of hospitalization. Results: Clinical manifestations recovery of COVID-19 patients was better in the favipiravir group, and the mortality rates were less than in the control group (P = 0.0001 for both). The level of blood oxygen saturation (SpO2) was significantly higher in the favipiravir group (P = 0.0001). The mean lymphocyte count was lower in the control group (P = 0.004). In addition, levels of blood urine nitrogen (BUN) were higher in the favipiravir group (P = 0.033). The length of hospitalization was similar in both groups (P = 0.586). Conclusion: Favipiravir can be effective for clinical and laboratory improvement of COVID-19 patients, and it is a promising drug for decreasing of mortality rate in these patients.

Efficacy of ketamine, propofol, and dexmedetomidine for anesthesia in electroconvulsive therapy in treatment-resistant major depressive disorder patients: a double-blind randomized clinical trial.

Electroconvulsive therapy (ECT) is one of the therapeutic opportunities for patients with psychological disorders when they may decline to take medication. We sought to systematically compare the anesthetic efficacy of ketamine, propofol, and dexmedetomidine for electroconvulsive therapy in treatment-resistant major depressive disorder patients. This double-blind trial enrolled treatment-resistant major depressive disorder patients (n = 85) who had been hospitalized for ECT in the Amir Kabir Hospital's psychiatric ward (Arak, Iran). The ketamine, propofol, and dexmedetomidine groups received a dose of 0.2 µg/kg ketamine, 1.5 mg/kg propofol, and 0.8 mg/kg dexmedetomidine, respectively. In all intervention groups, 10 mL of interventional drugs was injected intravenously for 10 minutes, and in the placebo group, 10 mL of normal saline was given over the same period. The dexmedetomidine group's blood pressure was revealed comparatively lower at all times. Dexmedetomidine-treated patients showed their marked satisfaction, while those treated with propofol had shorter recovery time, shorter seizure duration, and shorter time to achieve an Aldrete score of 9-10 and increased relaxation, and next dexmedetomidine produced deeper relaxation. Propofol could shorten recovery time and seizure duration, and enhance relaxation, while dexmedetomidine was associated with higher patient satisfaction. Considering that any anesthetic which does not shorten seizure duration may serve efficiently for ECT and that ketamine-treated patients had more prolonged seizure duration, the preferred drug can hence be considered from various angles, thereby offering anesthetic agents with highly favorable efficacy in treatment-resistant major depressive disorder patients needing ECT. The drug choice thus depends on physical conditions, underlying diseases, and psychiatrist consultation.

Guillain-Barré syndrome following COVID-19 vaccine: A case report.

Coronavirus disease is a viral infection affecting different organs with various morbidities and mortality. Vaccines are used to control the disease. COVID-19 vaccines have brought many benefits but their adverse effects should not be ignored. Here, we report a case of Guillain-Barré Syndrome Following Sinopharm COVID-19 Vaccine.

Comparison of three interventional approaches to prevent ventilator-associated pneumonia in intensive care units (ICUs): A clinical trial study.

BACKGROUND: Ventilator-associated pneumonia (VAP) is an infectious pulmonary disease that develops after 48 hours of ventilation. To date, several methods have been proposed to reduce VAP occurrence, such as the VAP prevention bundle, which involves raising the head of the bed, reducing sedation, avoiding deep vein thrombosis, and preventing peptic ulcer in the gastrointestinal system. The purpose of this study was to evaluate the role of personnel in hand washing, case airway suctioning, and systematic monitoring in the prevention of VAP. METHODS: In the current clinical trial, 129 patients hospitalized and intubated at Vali-e-Asr Hospital ICU in Arak, Iran, were included in the study and randomized to one of the three VAP prevention methods: group A, VAP prevention bundle measures; group B, group A measures plus washing of patients' mouth with 0.12% chlorhexidine and suction of secretion every six hours; and finally group C, group B measures plus 72-hour suction package. Demographic information, VAP diagnosis, and outcome of each patient were recorded in the special checklist. RESULTS: The age of the patients ranged from 18 years to 93 years with a mean of 54.6 ± 21.8 years. There was no significant difference in age, sex, Clinical Pulmonary Infection Score (CPIS), and Glasgow Coma Scale (GCS) between the three groups. However, there is a significant relationship between chest X-ray (CXR) index and pneumonia in the three groups (p < 0.05). The prevalence of pneumonia is generally seen to be higher in patients who were local, diffuse, or patchy than those who had no infiltration (p < 0.05). CONCLUSION: This study showed that the application of VAP prevention bundle measures, mouthwash with chlorhexidine, personnel hand washing, airway suctioning, and systematic monitoring is an efficient approach to the prevention of VAP in ICUs.

Effect of Inhaled Colistin on the Treatment of Ventilator-Associated Pneumonia due to Multi-drug Resistant Acinetobacter.

BACKGROUND: Ventilator-Associated Pneumonia (VAP) is a hospital pneumonia that is considered in patients on mechanical ventilation for at least 48 hours with symptoms of new lower respiratory tract infections being reported in them. The present study reviews the effect of adding inhaled colistin in the treatment of ventilator-induced pulmonary infections in Intensive Care Unit (ICU) patients. MATERIALS AND METHODS: In this single blind clinical trial, patients admitted to the ICU with diagnosis of pulmonary infections caused by ventilator were investigated. In the treatment group, patients received 150 mg of colistin plus 1,000,000 units inhaled colistin every eight hours and in the control group only 300 mg of colistin every eight hours intravenously was given. Patients were followed up in terms of clinical findings for seven days after the initial diagnosis of infection. RESULTS: The results of this study showed that administration of inhaled colistin in patients admitted in ICU significantly improved culture indices, leukocyte, white blood cell count, chest X-ray, chest secretion, CPIS score and saccharification (SpO2) on the third and seventh days after treatment compared to the first day. CONCLUSION: Considering the positive effect of adding inhaled colistin to the treatment of patients admitted to ICU with pulmonary infections caused by ventilator with multi-drug resistant Acinetobacter, the use of combination drug therapy is recommended.
