Pleural and pericardial effusions with cardiac conduction system and myocardial involvement: A rare presentation of sarcoidosis.

Sarcoidosis is a granulomatous immune disorder that can infiltrate many organ systems. When the cardiac system is involved, the myocardium and conduction system are frequently affected. We report the case of a patient presenting with complete heart block following cardioversion from atrial flutter accompanied by pleural and pericardial involvement whose diagnosis of sarcoidosis was subsequently made on pathological examination. Pericardial effusion and pleural effusion are rare manifestations of sarcoid, and the both of them happening simultaneously (less than 10 case reports) in conjunction with cardiac conduction system and myocardial involvement are almost nonexistent in the literature (one case report). As cardiac involvement in sarcoid can drastically increase the mortality, it is important to be vigilant for the diverse manifestations of cardiac involvement in all patients for which there is clinical suspicion of sarcoid.

Development and Validation of a Questionnaire to Assess Knowledge and Attitudes toward COVID-19 Preventive Measures in Romania.

The World Health Organization warns about the threat of the COVID-19 sixth wave. Our aim was to propose the first validated Romanian questionnaire to assess people's level of education and attitudes towards general measures to protect against COVID-19 infection. Our study was conducted on a sample of 194 people. The first version of the questionnaire consisted of 40 items. Items that did not meet psychometric criteria were removed. Latent components/factors were identified through exploratory factorial analysis (EFA). The Cronbach's alpha coefficient was used to assess internal fidelity. The EFA identified three factors. Factor 1 was named "Compliance with protective measures", factor 2 was "Attitudes toward vaccination" and factor 3 was "Attitudes regarding potential COVID-19 therapies". The final version of the questionnaire consists of 16 items. The test's final score predicted the presence of vaccination with an accuracy of 0.773. The questionnaire score, the diagnosis of diabetes, the advice provided by healthcare workers and the medical profession proved to be significant predictors of vaccination. The implementation of our questionnaire within national programs could identify populational areas that need specific interventions to reach vaccination targets and prevent a full-blown sixth wave of the COVID-19 pandemic in Romania.

Determinants of the Hesitancy toward COVID-19 Vaccination in Eastern European Countries and the Relationship with Health and Vaccine Literacy: A Literature Review.

Herd immunity is necessary to control the coronavirus disease 2019 (COVID-19) pandemic. However, a low proportion of vaccinated people and low levels of vaccine acceptance have been noted in Eastern Europe. Our paper aimed to review the central attitudes associated with the hesitancy toward COVID-19 vaccination specific to Eastern European countries. The main Eastern European determinants of COVID-19 vaccine acceptance identified from the included studies are: public confidence in the vaccines' safety and efficacy, vaccine literacy, and public trust in the government and the medical system. Each of these determinants is discussed along with possible improvement measures. Variables specific to Eastern Europe that predict the willingness to vaccinate have also been highlighted. The specific attitudes and their context as identified by our review should be incorporated into local public health programs, with the ultimate goal of reducing viral spreading, mutation emergence, and COVID-19 morbidity and mortality both within the borders of Eastern Europe and beyond.
