RESUMO
OBJECTIVE: Seizures have been reported as an adverse event of the COVID-19 vaccine. However, there is no solid evidence of increased seizure occurrence compared to the general population. This study was undertaken to investigate seizure occurrence among COVID-19 vaccine recipients compared to unvaccinated controls. METHODS: A systematic search was made of PubMed, Web of Science, Scopus, and Cochrane Library up to April 9, 2024. Studies reporting seizure occurrence following COVID-19 vaccination were included. This study is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework and was conducted using random- and common-effect models. The risk of bias in the studies was evaluated by the Newcastle-Ottawa Scale. The outcome of interest was new onset seizure incidence proportion compared among (1) COVID-19 vaccine recipients, (2) unvaccinated cohorts, and (3) various types of COVID-19 vaccines. RESULTS: Forty studies were included, of which seven entered the meta-analysis. Results of the pooled analysis of the new onset seizure incidence (21- or 28-day period after vaccination) in 13 016 024 vaccine recipients and 13 013 262 unvaccinated individuals by pooling the cohort studies did not show any statistically significant difference between the two groups (odds ratio [OR] = .48, 95% confidence interval [CI] = .19-1.20, p = .12, I2 = 95%, τ2 = .7145). Pooling four studies accounting for 19 769 004 mRNA versus 47 494 631 viral vector vaccine doses demonstrated no significant difference in terms of new onset seizure incidence between the groups (OR = 1.18, 95% CI = .78-1.78, p = .44, I2 = 0%, τ2 = .004). SIGNIFICANCE: This systematic review and meta-analysis shows no statistically significant difference in the risk of new onset seizure incidence between COVID-19 vaccinated individuals and unvaccinated individuals.
RESUMO
The COVID-19 pandemic has been extra challenging for patients with chronic diseases. Psoriasis is one of the chronic conditions that its treatment mostly relies on immunosuppressants. In this study, we report two cases with a long history of psoriasis that COVID-19 infection caused them to undergo erythrodermic psoriasis.
RESUMO
AIM: To conduct a cost-utility analysis of the tele-retinopathy of prematurity (ROP) screening program against no screening. METHODS: A decision tree model was developed to identify and treat the infants with threshold ROP through the tele-screening system compared with no screening program from the societal perspective. We used the quality adjusted life years (QALY) index to measure the scenarios' effectiveness, which was discounted for the future years by 0.058. One hundred twenty-six randomly selected newborns with ROP required treatment were investigated to extract the treatment information. We considered the direct medical and non-medical costs in cost calculations analysed by the bottom-up approach. The figures of the model's inputs were calculated using the Monte Carlo simulation that generated 1000 random iteration of the data, and a one-way sensitivity analysis was performed on the model to cope with the potential uncertainties. RESULTS: The total and per capita needed the budget to establish a tele-ROP screening system were estimated at over 1.5 million and 35.13 USD, respectively. The total cost of identifying and treating an ROP case in tele-screening and no screening strategies were obtained as 108.72 and 63.52 USD, respectively, and their lifetime discounted QALY gained were calculated as 15.39 and 15.11, respectively. Therefore, incremental cost-effectiveness ratio (ICER) of tele-screening strategy against the competitive strategy was achieved as 161.43 USD. CONCLUSION: Tele-ROP screening program is one of the most cost-effective interventions in the Iranian health system and has a high priority to receive a budget for implementation.
