Background Vaccination is a key intervention to prevent COVID-19. Many vaccines are administered globally, yet there is not much evidence regarding their safety and adverse effects. Iran also faces this challenge, especially as data regarding the Sputnik V vaccine is sparse. Therefore, the aim of this study is to determine the adverse effects of the most commonly used vaccines in Iran. Methods Using a retrospective cohort study design, 6600 subjects aged 18 years or older who had received two doses of any of the three COVID-19 vaccines (Sinopharm, AstraZeneca, and Sputnik V) were selected using a random sampling method between March and August 2021. Subjects were asked about any adverse effects of the vaccines by trained interviewers via telephone interview. Vaccine-related adverse effects in individuals during the first 72 h and subsequently following both doses of the vaccines were determined. The demographic variables, type of administered vaccine, adverse effects, and history of the previous infection with COVID-19 were collected. Descriptive statistics (mean, standard deviation) and analytical statistics (Chi-squared and Wilcoxon tests) were performed at a 95% significance level using STATA software version 15 (STATA Corp, College Station, TX, USA). Results From 6600 participants, 4775 responded (response rate = 72.3%). Of the participants, 1460 (30.6%) received the AstraZeneca vaccine, 1564 (32.8%) received the Sinopharm vaccine and 1751 (36.7%) received the Sputnik V vaccine. 2653 participants (55.56%) reported adverse effects after the first dose and 1704 (35.7%) after the second dose. Sputnik V caused the most adverse effects with 1449 (82.7%) vaccine recipients reporting symptoms after the first or second dose, compared with 1030 (70.5%) for AstraZeneca and only 585 (37.4%) for the Sinopharm vaccine. The most common adverse effects after the first dose were fatigue (28.37%), chill/fever (26.86%), and skeletal pain (22.38%). These three adverse effects were the same for the second dose, although their prevalence was lower. Conclusions In this study, we demonstrate that the Sputnik V vaccine has the highest rate of adverse effects, followed by the AstraZeneca and Sinopharm vaccines. COVID-19 vaccines used in Iran are safe and there were no reports of serious adverse effects.
IntroductionCompulsory treatment has decades of history in Iran; both before and after the Islamic Revolution, but there are many debates regarding its efficacy and effectiveness. Retention Rate is one of the best indices to estimate the efficacy of treatment. This study will compare Retention Rate among people referred from compulsory treatment centers and volunteer participants.MethodsThis was a retrospective (historical) cohort study that has been conducted among people who were taking methadone maintenance treatment (MMT). The study sample was selected from the MMT centers that admit both referral patients from compulsory centers and voluntary patients. All newly admitted patients from March 2017 to March 2018 were enrolled and followed up until March 2019.ResultsA total of 105 participants were recruited for the study. All were males with a mean age of 36.6 ± 7.9 years. Fifty-six percent of individuals were referred from compulsory residential centers. The total one-year retention rate of participants in this study was 15.84%. The one-year retention rate for the patients referred from compulsory residential centers and the non-referred patients was 12.28 and 20.45%, respectively (value of p = 0.128). Among the other studied factors, only marital status was significantly associated with MMT retention (p = 0.023).ConclusionAlthough the average treatment adherence time for non-referred patients was about 60 days higher than those referred from compulsory residential centers, this study found no significant differences in retention days and a one-year retention rate. Further studies with larger sample sizes and longer follow-ups are needed to explore the efficacy of compulsory treatment methods in Iran.
Coronavirus disease 2019 (COVID-19) affects millions of people worldwide. Clinical manifestations range from asymptomatic to severe viral pneumonia. CVID patients with COVID-19 infection are not adequately studied. In some studies, CVID patients had higher mortality rates, although other studies showed that CVID patients might have an uncomplicated COVID-19 infection. We describe 14 cases of COVID-19 infection in Iranian CVID patients in this study, including clinical manifestations, laboratory findings, and treatment strategies. There were 29% of patients with mild disease, 43% with moderate disease, and 29% with severe disease in this study. A critical case and a death occurred in none of our patients. There were six cases of infection more than two weeks after receiving the second dose of Sinopharm BIBP COVID-19 vaccine; all had mild to moderate disease. Among these patients, Remdesivir was the most frequently prescribed medication. According to this study, most of our patients presented with an uncomplicated disease course.
In the field of epidemics, some vulnerable groups, such as older adults, are at greater risk. Many psychological, social, economic and physical hazards have threatened older adults during the COVID-19 pandemic. Some threats can be managed with medical system interventions. However, social and psychological challenges cannot be controlled quickly. People will have a better quality of life if they can take appropriate action in critical situations. There is a strong theoretical and empirical background that a sense of control and self-efficacy can promote psychological well-being. The main questions of this study included the following: What were the main problems experienced by older Iranian women during the outbreak of COVID-19? What coping methods did they use to control the situation? What were their views on the future? This research was conducted in Kerman city, the capital of Kerman Province. A phenomenological method was used. We interviewed 15 women over 65 years old. We extracted five main themes from the interviews. These themes were health issues, persistent anxiety, economic and social pressures, identifying unique solutions to the current situation, and optimism versus pessimism: what is the future? From the participants' point of view, psychological, social and physical problems have disturbed them during the pandemic, especially at the beginning. However, they controlled their problems by using selective coping strategies. In Iran, planners can use the potential of the two institutions of family and religion to reduce the problems of older adults.
