Background Although almost a year has passed since the Coronavirus disease 2019 (COVID-19) outbreak and promising reports of vaccines have been presented, we still have a long way until these measures are available for all. Furthermore, the most appropriate corticosteroid and dose in the treatment of COVID-19 have remained uncertain. We conducted a study to assess the effectiveness of methylprednisolone treatment versus dexamethasone for hospitalized COVID-19 patients. Methods In this prospective triple-blinded randomized controlled trial, we enrolled 86 hospitalized COVID-19 patients from August to November 2020, in Shiraz, Iran. The patients were randomly allocated into two groups to receive either methylprednisolone (2 mg/kg/day; intervention group) or dexamethasone (6 mg/kg/day; control group). Data were assessed based on a 9-point WHO ordinal scale extending from uninfected (point 0) to death (point 8). Results There were no significant differences between the groups on admission. However, the intervention group demonstrated significantly better clinical status compared to the control group at day 5 (4.02 vs. 5.21, p = 0.002) and day 10 (2.90 vs. 4.71, p = 0.001) of admission. There was also a significant difference in the overall mean score between the intervention group and the control group, (3.909 vs. 4.873 respectively, p = 0.004). The mean length of hospital stay was 7.43 ± 3.64 and 10.52 ± 5.47 days in the intervention and control groups, respectively (p = 0.015). The need for a ventilator was significantly lower in the intervention group than in the control group (18.2% vs 38.1% p = 0.040). Conclusion In hospitalized hypoxic COVID-19 patients, methylprednisolone demonstrated better results compared to dexamethasone. Trial registration The trial was registered with IRCT.IR (08/04/2020-No. IRCT20200204046369N1).

Objective With the novel coronavirus pandemic, the impact on the healthcare system and workers cannot be overlooked. However, studies on the infection status of medical personnel are still lacking. It is imperative to ensure the safety of health-care workers (HCWs) not only to safeguard continuous patient care but also to ensure they do not transmit the virus, therefore evaluation of infection rates in these groups are indicated. Methods Demographic and clinical data regarding infected cases among HCWs of Fars, Iran with positive SARS‐CoV‐2 PCR tests were obtained from 10th March to 17th May 2020. Results Our data demonstrated a rate of 5.62% (273 out of 4854 cases) infection among HCW, with a mean age of 35 years and a dominance of female cases (146 cases: 53.5%). The majority of infected cases were among nurses (51.3%), while the most case infection rate (CIR) was among physicians (27 positive cases out of 842 performed test (3.2%)). Also, the highest rate of infection was in the emergency rooms (30.6%). Also, 35.5% of the patients were asymptomatic and the most frequent clinical features among symptomatic patients were myalgia (46%) and cough (45.5%). Although 5.5% were admitted to hospitals, there were no reports of ICU admission. Furthermore, 10.3% of the cases reported transmitting the infection to family and friends. Regarding safety precautions, 1.6% didn't wear masks and 18.7% didn't use gloves in work environments. Conclusion HCWs are among the highest groups at risk of infection during the COVID-19 pandemic; therefore, evaluating infection rates and associated features is necessary to improve and adjust protective measures of these vulnerable, yet highly essential group.

Background: In March 2020, the WHO declared the novel coronavirus (COVID-19) outbreak a global pandemic. Although the number of infected cases is increasing, information about its clinical characteristics in the Middle East, especially in Iran, a country which is considered to be one of the most important focal points of the disease in the world, is lacking. To date, there is no available literature on the clinical data on COVID-19 patients in Iran. Methods: In this multicenter retrospective study, 113 hospitalized confirmed cases of COVID-19 admitted to university affiliated hospitals in Shiraz, Iran from February 20 to March 20 were entered in the study. Results: The mean age was 53.75 years and 71 (62.8%) were males. The most common symptoms at onset were fatigue (75: 66.4%), cough (73: 64.6%), and fever (67: 59.3%). Laboratory data revealed significant correlation between lymphocyte count (P value = 0.003), partial thromboplastin time (P value = 0.000), international normalized ratio (P value = 0.000) with the severity of the disease. The most common abnormality in chest CT scans was ground-glass opacity (77: 93.9%), followed by consolidation (48: 58.5%). Our results revealed an overall 8% (9 out of 113 cases) mortality rate among patients, in which the majority was among patients admitted to the ICU (5: 55.6%). Conclusion: Evaluating the clinical data of COVID-19 patients and finding the source of infection and studying the behavior of the disease is crucial for understanding the pandemic.

Background In March 2020, WHO has declared pandemic on COVID-19. Although the number of infected cases is increasing, information about its clinical characteristics in the Middle East especially in Iran, a country which is considered as one of the most important foci of the disease in the world is lacking. Till date, there is no available literature on the clinical data on COVID-19 patients in Iran. Method and Material: In this multicenter retrospectively registered study, 113 hospitalized confirmed cases of COVID-19 admitted in university affiliated hospitals in Shiraz, Iran in from February 20 to March 20 were enrolled. Results The median age was 53 years and 71 (62.8%) were males. The most common symptoms at onset were fatigue (75: 66.4%), cough (73: 64.6%), and fever (67: 59.3%). Laboratory data revealed significant correlation between lymphocyte count, partial thromboplastin time, international normalized ratio with the severity of the disease (P value = 0.003, 0.000, 0.000, respectively). The most common abnormality in chest CT scan was ground-glass opacity (77: 93.9%), followed by consolidation (48: 58.5%). Our results revealed an overall 8% (9 out of 113 cases) mortality rate among the patients, in which the majority was among the ICU admitted patients (5: 55.6%). Also, 68 (60.2%) of our patients achieved total recovery and 7 (6.2%) were discharged with follow-up and home isolation. Conclusion In this multi-center study which included 113 hospitalized patients with diagnosis of COVID-19, 9.7% of cases were transferred to ICU and mortality rate was 8%. Furthermore, finding the source of infection and studying the behavior of COVID-19 is crucial for understanding the pandemic.

Background Disease outbreak not only carries the risk of death to the public due to the infection, but it also can lead to unbearable psychological impact on the mental health of the individuals. This study aims to explore and evaluate the burden of psychological problems on the Iranian general population during the outbreak of COVID-19. Method A cross-sectional web-based survey was conducted among the general population of Iran age 15 and above. Demographic variables, depression, and anxiety symptoms were evaluated using the Patient Health Questionnaire-9 and General Anxiety Disorder-7 questionnaires. Results Among the 8591 participants, the mean age was 34.37 (± 11.25) years and 66.4% were female while 33.6% were male. Based on our results, 1295 (15.1%) and 1733 (20.1%) of the general population had clinically significant depressive and anxiety symptoms, respectively. Based on the demographic variables, female gender was associated with a higher risk for developing depression and anxiety symptoms, whereas getting information about the disease from medical journals and articles, being older, and being married were considered as associated protective factors. In terms of depression, being a healthcare worker was an associated risk factor. On the other hand, for anxiety, having higher education was a protective factor while a higher number of individuals in a household was considered as a risk factor. Conclusions This study identified a major mental health problem in the Iranian population during the time of the COVID-19 outbreak. Therefore, establishing a targeted mental health support program during the time of public emergencies, such as the disease outbreak, is advised.

Background School closure is one of the main policies of global health care strategies performed worldwide. Despite all benefits, there might be some threats for younger groups spending their time in quarantine. This study aims to determine the impacts of lockdown and school closure on children’s major lifestyle aspects, especially their leisure and sleep pattern during the COVID-19 pandemic. Methods For the purpose of this study, an online questionnaire was distributed from 14th to 31st of March 2020 among the schools and students from the first grade to the 12th grade (before university) in Fars province, southern Iran. The questionnaire consisted of five sections which included data regarding the students’ general information, activity priorities, adherence to quarantine, attitude toward school closure, and sleep patterns. Results In our study, 20,697 filled questionnaires were received from the participants with an average age of 13.76 years; 29.7% of them were male, 80.6% were from urban areas, and 83.3% were from public schools. The overall first preference of students during school closure was mobile and computer games (30.1%), followed by studying (26.6%) and watching television (13.8%). Our results demonstrated that the majority of students adhered to social distancing and there was also a significant correlation among education levels and desire for schools to be closed till the end of the semester (P = 0.015). Also, regarding sleep patterns, the majority (53.5%) had above 12 h of sleep throughout the day. Conclusion It seems that lockdown following COVID-19 pandemic has changed various aspects of the students’ lifestyle remarkably, especially by increasing screen time and even sleep duration and pattern. We believe that certain strategies should be implemented by the Health and Educational Ministry to control not only the visible side effects of the quarantine period, but also the collateral consequences on their psychological and mental health.

Introduction. Burning mouth syndrome (BMS) is one of the challenging clinical problems not only in its diagnosis and treatment but also its concurring mental impact. This study is aimed at determining the association between psychological factors, including emotional stress, depression, anxiety, and sleep pattern among BMS patients. Methods. In this cross-sectional study, 19 patients with idiopathic BMS were enrolled along with a control group equivalent in age and sex, but without BMS. Questionnaires used were the Visual Analog Scale (VAS), the Pittsburgh Sleep Quality Index (PSQI), and the Depression, Anxiety, and Stress Scale (DASS-21). Demographic information was also recorded and analyzed. Results. There was a significant correlation among the two groups of BMS and non-BMS patients regarding stress, depression, and sleep disorder. The average severity of the burning score was 8.31 among the patients. Furthermore, a significant correlation was observed among mental disorders and educational level and sex, but not with age. There was also no significant correlation among the severity of the burning score with sex, education, and mental disorder. Conclusion. BMS is significantly associated with psychological symptoms. This condition requires proper treatment and support because it can represent psychological or mental issues and/or have a significant effect on daily life.
