Case Reports
Exacerbation of branch retinal vein occlusion post SARS-CoV2 vaccination: Case reports.
In this paper, we report on 2 patients who developed branch retinal vein occlusion (BRVO) exacerbation 1 day after administration of the BNT162b2 (Pfizer-BioNTech) SARS-CoV-2 vaccine. ⋯ Both cases showed a possible association between SARS-CoV-2 vaccination and the exacerbation of BRVO.

Review Meta Analysis
How efficient are facial masks against COVID-19? Evaluating the mask use of various communities one year into the pandemic.
Face masks are devices worn over the mouth and nose to protect against splashes, infectious respiratory droplets, or aerosols generated during breathing or coughing according to their filtering capacity. Medical masks, respirators, or cloth masks have been used for source control and for the protection of the exposed. After the first case on March 11, 2020, in Turkey, National COVID-19 Scientific Advisory Board published various contents for the correct use of masks. ⋯ Metaanalysis, case control, cross sectional, cohort, retrospective, retrospective cross sectional, research, randomized controlled, and controlled comparison studies were reviewed on the protective effect of masks on COVID-19 with laboratory evidence. Optimum use of face masks with additional precautions has been found to be useful controlling the spread of the respiratory viruses such as SARS-CoV-2 in most of the studies and metaanalyses. As a conclusion, the recent evidence in COVID-19 pandemic is consistent with the previous studies which have shown association between face mask use and decreased risk of viral infections, and medical face mask use should be encouraged both for the community and healthcare facilities along with other infection control measures such as hand hygiene, during outbreaks when there is widespread community transmission.

There have been several local and systemic adverse events associated with mRNA COVID-19 vaccines. Pericarditis, myocarditis and myocardial infarction are examples of cardiac complications related to these vaccines. In this article, we conducted a systematic review of case reports and case series to identify the clinical profile, investigations, and management of reported cardiac complications post-mRNA COVID-19 vaccines. ⋯ We acknowledge that only reviewing case reports and case series studies is one potential limitation of our study. We found that myocarditis was the most commonly reported adverse cardiac event associated with mRNA COVID-19 vaccines, which presented as chest pain with a rise in cardiac biomarkers. Further large-scale observational studies are recommended.

Currently there is not an effective antiviral treatment for COVID-19, but a large number of drugs have been evaluated since the beginning of the pandemic, and many of them have been used for the treatment of COVID-19 despite the preliminary or conflicting results of the clinical trials. We aimed to review and summarize all of the current knowledge on the antivirals for COVID-19 ⋯ When taking into account the results of all the available laboratory and clinical trials on the subject, monoclonal antibodies seem to be the most effective treatment for COVID-19 at the moment, and high-titer convalescent plasma also could be effective when administered during the early phase of the disease. As lopinavir/ritonavir, hydroxychloroquine, merimepodib, and umifenovir were found to be ineffective in RCTs, they should not be used. Additional studies are needed to define the role of remdesivir, favipiravir, interferons, ivermectin, dutasteride, proxulutamide, fluvoxamine, bromhexine, nitazoxanide, and niclosamid in the treatment of COVID-19. Finally, the results of phase trials are waited to learn whether or not the newer agents such as molnupiravir, PF-07321332, PF-07304814, plitidepsin and AT-527 are effective in the treatment of COVID-19.

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has alarmed the world since its first emergence. As pregnancy is characterized by significant changes in cardiovascular, respiratory, endocrine, and immunological systems, there are concerns on issues like the course of disease in pregnant women, safety of medications, route of delivery and risk of obstetric complications. The aim of this review is to summarize the current literature in the management of pregnant women during the COVID-19 pandemic. ⋯ Cesarean delivery should be performed for obstetric indications. Breast feeding should be encouraged as long as necessary precautions for viral transmission are taken. In conclusion, an individualized approach should be provided by a multidisciplinary team for the management of pregnant women with COVID-19 to achieve favorable outcomes.
