A systematic review and meta-analysis on the prevalence and impact of coronary artery disease in hospitalized COVID-19 patients.

Background: COVID-19 accounts for more than half a billion deaths globally. The clinical manifestations may vary in due course. Despite several studies aimed at determining the extent to which the disease's severity and mortality remain high when combined with other comorbidities, more research is required. Therefore, this review aimed to measure the pooled prevalence of coronary artery disease (CAD) among COVID-19 patients, specifically those with a history of CAD. Additionally, we aim to assess the association between mortality due to CAD and the severity of COVID-19 among hospitalized patients. Method: A comprehensive search in PubMed, Web of Science, the Cochrane Library, and the WHO COVID-19 database was conducted. English studies with original data on CAD, mortality, and ARDS among COVID-19 patients were included. PRISMA guidelines were followed. Results: Among the 2007 identified articles, 76 studies met the inclusion criteria. The pooled prevalence of CAD among COVID-19 patients was 14.4%(95% CI: 12.7-16.2). The highest prevalence was observed in European studies at 18.2%(95% CI: 13.3-24.2), while the lowest was in Asian studies at 10.4% (95% CI: 6.4-16.3). Participants with concurrent CAD at the time of hospital admission had twice the odds of mortality due to COVID-19 (2.64 [95% CI: 2.30-3.04]) with moderate heterogeneity (I2 = 45%, p < 0.01). Hospitalized COVID-19 patients with CAD had a 50% higher risk of ARDS (95% CI: 0.62-3.66), but this difference was not statistically significant. Conclusion: Although our analysis revealed evidence for a relationship between concurrent CAD at the time of hospital admission and mortality from COVID-19, however, global variation in health infrastructure, limitations of data reporting, and the effects of emerging variants must be considered in future investigations.

Relationship between job stress and work-related quality of life among emergency medical technicians: a cross-sectional study.

OBJECTIVE: This study was aimed to determine the relationship between job stress and work-related quality of life (WRQoL) among emergency medical technicians (EMTs) in Lorestan province, Western Iran. DESIGN: This was a cross-sectional study. METHODS: Totally 430 EMTs who had been engaged in their respective units for more than 6 months from all emergency facilities in Lorestan province were selected using single stage cluster sampling method. Data were collected from April to July 2019 using two standard questionnaires: job stress (Health and Safety Executive (HSE)) and WRQoL. The OR with 95% CI was used to declare the statistical association (p≤0.05). RESULTS: All participants were exclusively males, with a mean age of 32±6.87 years. The overall average score of job stress using the HSE scale was 2.69±0.43; while the overall quality of working life score was 2.48±1.01. The type of working shift was found to have a significant impact on the HSE-average score (F(3,417)=5.26, p=0.01); and on the WRQoL-average score (F(3,417)=6.89, p<0.01). CONCLUSION: Two-thirds of EMTs working in governmental hospitals had job stress and a low quality of work-related life. Additionally, work shift was statistically significant associated with EMTs' job stress and WRQoL.

Investigate the relationship between cell-phone over-use scale with depression, anxiety and stress among university students.

BACKGROUND: Cell phones have increased dramatically as a new communication technology in the modern world. This study aimed to determine the relationship between cell phone over use scale with depression, anxiety and stress among university students in Khorramabad, Iran. METHODS: In this descriptive-analytical and cross-sectional study, 212 students were randomly selected from the Lorestan University of Medical Sciences by a combination of stratified and clustered random sampling. Data were collected by two standard questionnaires including, Cell-phone Over-use Scale (COS) and Depression, Anxiety and Stress (DASS-21) and were analyzed using SPSS V.22. RESULTS: Based on the results, 72.2% of the students were exclusively male, which a majority of them were in age of 21-23 years (46.2%), and 92.5% were single. Based on the multiple linear regression and after adjustment for the confounding effect, there was a significant relationship between cell phone over use scale on student's stress (t = 2.614, P = 0.010), and student's anxiety (t = 2.209, P = 0.028); however there was not a significant relationship between cell phone over use scale on student's depression (t = 1.790, P = 0.075). CONCLUSIONS: Harmful use of cell phones can aggravate psychological disorders such as anxiety, stress and depression and by controlling this factor can increase the level of mental health and improve the quality of life in students.

Post-pandemic stress of COVID-19 among high-risk groups: A systematic review and meta-analysis.

BACKGROUND: Post-Traumatic Stress Disorder (PTSD) is considered as a prevalent outcome of the COVID-19 pandemic. This study aimed to present a global picture of the prevalence of PTSD in high-risk groups for COVID-19 (HRGs-COVID19) and determine its risk factors. METHODS: Cross-sectional studies published between March 11, 2020, and October 11, 2021, in English, were searched in seven databases on the prevalence of PTSD in HRGs-COVID19. After screening the retrieved records, their quality was assessed, and the required data were extracted. R-4.1.3 software and random effect model with 95 % confidence interval (CI) were used to synthesize and analyze the data. RESULTS: The pooled prevalence of PTSD in HRGs-COVID19 was 30 % (95 % CI: 21-39 %). The pooled prevalence of PTSD was significantly different in terms of the variables of data collection during the lockdown, gender, and data collection season (P < 0.05). Subgroup analyses could not identify sources of heterogeneity. LIMITATIONS: The included studies did not cover all HRGs-COVID19 such as smokers and the elderly. CONCLUSION: Considering the higher pooled prevalence of PTSD in HRGs-COVID19 than the general population, COVID-19 patients, and health care workers, prioritizing this subgroup for prevention and treatment of psychological outcomes is highly recommended. Predicting and implementing psychological interventions early in the pandemic is more critical when applying restrictive measures and among HRGs-COVID19 women.

Cerebral vein thrombosis in a woman using oral contraceptive pills for a short period of time: a case report.

BACKGROUND: Cerebral vein thrombosis is increasing in young adults. Although oral contraceptive pills increase the risk of cerebral vein thrombosis, relatively high brain venous involvement is rare when oral contraceptive pills are consumed for a short duration. CASE PRESENTATION: A 31-year-old Asian woman was referred to Imam Reza Hospital with a headache complaint on 11 November 2020. The woman, who had a headache for the previous 11 days, went to the hospital. Owing to endometriosis involvement, she consumed Diane tablets. According to the imaging findings, three vein involvements were diagnosed. Anticoagulant therapy was started, and the symptoms disappeared. CONCLUSIONS: All cerebral vein thrombosis symptoms are variable, but new presentation of headache could be an early symptom of cerebral vein thrombosis.

Two new cytotoxic ursane triterpenoids from the aerial parts of Salvia urmiensis Bunge.

Bioassay-guided fractionation of a dichloromethane extract of the aerial parts of Salvia urmiensis, an endemic plant species of Iran, led to the isolation of two new cytotoxic ursane triterpenoids, Salvurmin A and Salvurmin B. Their structures were elucidated by a combination of 1D and 2D NMR, HR-ESI-MS, IR and UV analysis. Cytotoxicity of the above-mentioned compounds were evaluated against two human cancerous cell lines (SW1116, MCF-7). IC50 values for Salvurmin A and Salvurmin B on colon cancer cell line (SW1116) were 41.6 ± 2.6 and 23.2 ± 0.4 µM respectively, in comparison to cisplatin as control positive. In addition, these two compounds exhibited cytotoxic activity on breast cancer cell line (MCF-7) with an IC50 of 54.2 ± 5.3 and 40.2 ± 3.1 µM for Salvurmin A and Salvurmin B, respectively. The cytotoxic activities of these two compounds present a promising potential for the future investigation on this endemic species of Salvia.
