Vaccination status and outcomes of COVID-19 patients admitted to a tertiary hospital in Iran during the dominant Delta variant period.

BACKGROUND: This study aimed to determine the characteristics, vaccination status, and outcomes of confidence interval (COVID-19) patients, admitted to a tertiary hospital in Iran during the predominant severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) Delta variant period. METHODS: This retrospective study assessed the medical records of all hospitalized COVID-19 patients, who were admitted to a tertiary hospital from July 10 to September 15, 2021. Adjusted binary logistic regression analyses were conducted to determine factors associated with poor outcomes. RESULTS: More than 25% of hospitalized patients received at least one vaccine dose of SARS-CoV-2. The Sinopharm BIBP vaccine (China) was the most commonly received vaccine (73.3%). After adjusting for age and comorbidities, the adjusted odds ratio (AOR) for poor outcomes was significantly lower in hospitalized patients who received Remdesivir compared to those not receiving Remdesivir (AOR: 0.35; 95% confidence interval [CI]: 0.15, 0.78; p < .010). Besides, age ≥50 years (AOR: 2.51; 95% CI: 1.38, 4.59; p < .003), low educational level (AOR: 3.99; 95% CI: 1.17, 13.53; p < .027), work outside in the past year (AOR: 1.75; 95% CI: 1.02, 3.00; p < .041), and diabetes mellitus (AOR: 1.95; 95% CI: 1.66, 3.26; p = .011) were associated with more poor outcomes. CONCLUSION: Based on the present results, the risk of mortality and the risk of poor outcomes were lower in patients who received Remdesivir compared to those not receiving Remdesivir. The number of vaccinated patients was smaller than the unvaccinated among hospitalized patients. It is important to emphasize that vaccination reduced the need for hospitalization and that only vaccinated patients with comorbidities required hospitalization.

Comparison of the Effect of Ceratonia siliqua L. (Carob) Syrup and Vitamin E on Sperm Parameters, Oxidative Stress Index, and Sex Hormones in Infertile Men: a Randomized Controlled Trial.

Herbal products with an antioxidant capacity can boost male reproductive functions. The empiric use of Ceratonia siliqua (carob) for its antioxidant properties is common among infertile men in Iran and Turkey. The objective of this study is to investigate the effects of C. siliqua (carob) on semen parameters, oxidative stress markers, and pregnancy rate in a parallel randomized, controlled study. A total of 60 infertile men with oligozoospermia, asthenospermia, and teratospermia were recruited from April 2018 to March 2019. Participants were divided randomly into the following two groups: carob syrup twice a day or vitamin E 100 mg twice a day for 3 months. Semen analysis was performed and hormonal levels and stress oxidative markers were measured in each treatment arm after 3 months. The quality of semen parameters improved in the carob group compared with Vit E semen count (p = 0.04 Cohen's d = .51), morphology (p = 0.001 Cohen's d = .93) and motility parameters (p = 0.002 Cohen's d = .90) were significantly higher in the carob group. No significant difference can be detected in post-treatment hormonal parameters and oxidative markers between groups, except for total antioxidant capacity(TAC) which was higher after post-treatment in carob group. A significantly higher pregnancy rate was found among the carob group. The administration of carob may be an effective agent for the improvement of semen parameters, probably related both to its involvement in the changing of testosterone level and to its antioxidant properties. Nevertheless, additional studies to evaluate the optimal dose and duration of treatment are needed. The trial has been registered in the Iranian Registry of Clinical Trials (Registration number: IRCT20171209037794N1.
