Abstract
Background Dysferlinopathies represent a group of limb girdle or distal muscular dystrophies with an autosomal-recessive inheritance pattern resulting from the presence of pathogenic variants in the dysferlin gene (DYSF). Objective In this work, we describe a population from a small city in Brazil carrying the c.5979dupA pathogenic variant of DYSF responsible for limb girdle muscular dystrophy type 2R and distal muscular dystrophy. Methods Genotyping analyses were performed by qPCR using customized probe complementary to the region with the duplication under analysis in the DYSF. Results A total of 104 individuals were examined. c.5979dupA was identified in 48 (46.15%) individuals. Twenty-three (22%) were homozygotes, among whom 13 (56.5%) were female. A total of 91.3% (21) of homozygous individuals had a positive family history, and seven (30.4%) reported consanguineous marriages. Twenty-five (24%) individuals were heterozygous (25.8±16 years) for the same variant, among whom 15 (60%) were female. The mean CK level was 697 IU for homozygotes, 140.5 IU for heterozygotes and 176 IU for wild-type homo-zygotes. The weakness distribution pattern showed 17.3% of individuals with a proximal pattern, 13% with a distal pattern and 69.6% with a mixed pattern. Fatigue was present in 15 homozygotes and one heterozygote. Conclusion The high prevalence of this variant in individuals from this small community can be explained by a possible founder effect associated with historical, geographical and cultural aspects.

Abstract
INTRODUCTION Brazil has been facing the pandemic of COVID-19 since march 2020. To date, more than 540,000 people have died from this disease in the country. There are estimates that indicate that the population exposed to SARS-CoV-2 represents 1 to 20%, however, these data are questionable due to the number of asymptomatic and untested individuals. As a result, vaccination for COVID-19 has become the main means of achieving herd immunity. OBJECTIVES To demonstrate, through local sampling, that broad and rapid vaccination may decrease the rate of COVID-19 detection in individuals potentially exposed to the SARS-CoV-2 virus. RESULTS A total of 1,128 individuals were studied, including students and health professionals from Centro Universitário FMABC, who received the two doses of the vaccine for COVID-19 (Oxford/Astrazeneca ® and CoronaVac®). There was a 41% reduction in the demand for RT-PCR test after vaccination, in the studied period. And a 78.3% reduction in positive results after vaccination started Conclusion: The results of this study showed that, even vaccinating a population with higher exposure to the risk of contamination, there was a significant reduction in test positivity and in the demand to perform these tests. Emphasizing that vaccination is the best strategy to achieve herd immunity and to reduce the spread of the disease.

Abstract
Introduction: Hemodialysis stands out as an eligible treatment for patients with chronic kidney disease. The subsequent inflammatory process resulting from this disease and hemodialysis per se is exacerbated in this therapy. Selenium (Se) is an essential trace element that can participate in the inhibition of pro-oxidant and pro-inflammatory processes and could be considered a measurement that indicates the progression of chronic kidney disease and inflammation. Objectives: The present study investigated selenemia in hemodialysis patients of the ABC region of São Paulo and aimed to establish the correlation between an inflammatory marker and selenemia in this conditions disease. Methods: This is an observational cross-sectional study of the Faculdade de Medicina do ABC in patients submitted to hemodialysis three times a week for at least six months. The eligible group composed of 21 patients, who filled out forms and underwent biochemical tests (colorimetric enzyme methods, flow cytometer, turbidimetric method and mass spectrometry). Results: The study population showed, women (70%), men (30%) with a mean age of 47 ± 17 years, Caucasians (36%) and non-Caucasian (64%), hypertensive (68%), smokers (53%) and non-smokers (64%). There was a hegemonic prevalence of systolic arterial hypertension (SAH) 68.1% in relation to diabetes mellitus (DM) (50%). Pre and post hemodialysis (HD) selenemia showed statistical significance, which did not occur with C-reactive protein. There was a predominance of females in our sample; the pre- and post-HD selenemia were within the normal range of the reference values; there was a statistically significant correlation between pre and post-HD selenemia; there was no correlation with statistical significance between values of pre and post-HD C-reactive protein. Conclusion: Our data showed that there was no direct relationship between pre- and post-HD inflammation and pre- and post-HD selenemia.
