The measures to control the COVID-19 pandemic in the academic 2020/2021 included full-time online courses for medical students in Serbia for the first time since the faculty was founded in 1920. The purpose of this study was to examine the attitudes and opinions about the full-time online course among medical students and their teachers. A qualitative study was carried out in the autumn of 2021. ⋯ Most participants considered that the online classes had a negative impact on their knowledge and practical skills, but their academic achievement was not inferior compared to previous years. The full-time online course should include conventional on-site teaching. The relevance of acquiring practical skills is strongly emphasized.

While severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes significant morbidity and mortality in humans, there is a wide range of disease outcomes following virus exposures. Some individuals are asymptomatic while others develop complications within a few days after infection that can lead to fatalities in a smaller portion of the population. In the present study, we have analyzed the factors that may influence the outcome of post-SARS-CoV-2 infection. ⋯ This is due to cross-reactive antibodies and T-cells that recognize SARS-CoV-2 antigens. We also have reviewed the current literature that has also proposed that human infections with eCOVIDs impart protection against disease caused by subsequent exposure to SARS-CoV-2. We propose that a nasal spray vaccine consisting of selected genes of eCOVIDs would be beneficial against SARS-CoV-2 and other pathogenic coronaviruses.

The existing data have shown inconsistency about the association between red cell distribution width (RDW) and hypertension. Thus, the aim of the present study was to investigate the association between RDW and newly diagnosed hypertension among adults in Sudan. This was a case-control study conducted in Northern Sudan from July to September 2022. ⋯ No association was found between RDW and newly diagnosed hypertension. No correlation was found between RDW and systolic (r = 0.045, P = 0.577) or diastolic blood pressure (r = 0.023, P = 0.772). In conclusion, no association in RDW was found between the patients with newly diagnosed hypertension and the healthy controls.

Vitiligo is a multifactorial dermatosis with many etiological hypotheses that have been suggested for its occurrence. To our knowledge, few epidemiological studies are available on vitiligo induction factors and particularly on the role of exposure to chemicals in the onset of the disease has been found. Therefore, there is need to investigate the relationship between vitiligo and chemical exposures in order to understand this mysterious disease. ⋯ Our results suggest that chemical factors play a key role in the occurrence of vitiligo. Therefore, prevention of this dermatosis requires the identification of exposure to the incriminated chemicals in any patient followed for vitiligo. The earlier the diagnosis of 'chemical' or chemically aggravated vitiligo, the better the prognosis for this disease.

Background: YKL-40, which is also known as Chitiniase 3-like 1, has been found to be up-regulated in many autoimmune diseases including asthma, systemic sclerosis and systemic lupus, etc. However, the relationship between serum levels of YKL-40 and one another common autoinmmue thyroid disease - Graves' disease (GD) has not yet been investigated. Objective: The current study was performed to investigate the correlation of serum YKL-40 levels with disease severity of initially diagnosed GD. ⋯ The positive correlations of YKL-40 in serum with the average superior thyroid artery velocity (STV) and thyroid tissue blood flow (TBF) were also observed. Conclusion: Our findings implicated that YKL-40 may be closely connected to the pathogenesis of GD. Increased YKL-40 levels are linked with disease severity of initially diagnosed GD.
