The objectives of this study were to estimate the serum prevalence of hepatitis C virus (HCV) infection in a dialysis center in the greater Recife region, and to correlate HCV serum positivity with some risk factors. Analyses were performed on 250 patients of both sexes, with ages ranging from 17 to 92 years old. Epidemiological data on these patients were obtained in order to determine the risk factors for this infection. Anti-HCV antibodies were investigated using fourth-generation ELISA. Statistically significant associations (p<0.05) were observed in relation to the risk factors of hemodialysis duration, number of blood component transfusions and time taken for transfusions. The prevalence was low (8.4%) in relation to other Brazilian studies. However, more studies in other centers are needed in order to estimate the real prevalence of HCV infection among patients undergoing hemodialysis in the State of Pernambuco.

The current study aims to evaluate histopathological and digital morphometrical aspects associated with uterine leiomyomas in one hundred and fifty (150) patients diagnosed with leiomyoma. Uterine tissues were subjected to the histopathological and digital morphometric analyses of the interstitial collagen distribution. The analysis of medical records indicates that most of the women diagnosed with uterine leiomyomas (68.7%) are between 37 and 48 years old. As for the anatomic location of the tumors, approximately 61.4% of the patients had intramural and subserosal lesions. In 50% of the studied cases, the patients developed uterine leiomyomatosis (with more than eight tumors). As for the morphometric study, the average size of the interstitial collagen distribution held approximately 28.53% of the capture area, whereas it was of 7.43% in the normal tissue adjacent to the tumor. Another important aspect observed in the current study was the high rate of young women subjected to total hysterectomy, a fact that resulted in early and definitive sterility.

The pathophysiology of Covid-19 has a cytokine storm, causing exacerbation of inflammatory lesions, mainly of the lungs and vascular endothelium. The mechanism of entry into the human cell uses the Angiotensin-Converting Enzyme 2 as a cell surface receptor. Among the most at-risk groups are pregnant women, due to the physiological, anatomical and immunological changes of the gestational cycle, causing susceptibility to infections. In addition, there are uncertainties about safe breastfeeding and possible vertical transmission. This group, which has a continuous obstetric follow-up, within pandemic circumstances, needed to minimize the risk of exposure in medical settings, using care through telehealth, as a helper. It was possible to replace some face-to-face visits to the clinic, when possible, by virtual ones, minimizing risks to exposure and providing a vehicle for direct communication with the doctor, which, in a way, offers pregnant women more peace of mind, essential to avoid possible complications by psychological stress that can generate inflammatory responses for mother and fetus, causing possible neuropsychiatric consequences. The objective of this narrative review study was to present an update of the data on the disease, as well as a change in management of the pregnant population. Despite being of great importance, virtual assistance does not replace face-to-face, and to get the most out of this new approach, there is a set of guidelines that can help health professionals. It is also important to warn of: changes in hospital management; reconciling ultrasound consultations with medical appointments, reducing the number of pregnant women leavings; telephone tracking of patients' symptoms before face-to-face attendance; and testing recommendations for covid-19, before entering hospitals.

To evaluate the scientific evidence about the fecal inflammatory biomarkers used in medical practice for the evaluation of disease activity and diagnosis of inflammatory bowel disease. Data source: Were evaluated articles of BVS databases, Scielo, Google Scholar, PubMed and Science Direct. The descriptors used in this review were "inflammatory bowel disease" AND ("diet" OR "nutrition"). They considered manuscripts published between 2014 and December 2019, available in full and published in English. Data synthesis: Initially identified 676 articles. The first selection, based on the analysis of the titles and abstracts of the 676 selected articles, resulted in 90 articles and after the complete reading of the manuscripts, 24 studies were considered eligible for analysis. No study has been conducted in Brazil. Conclusions:The studies analyzed in this systematic review increase that qualitative or quantitative changes in certain food groups in the composition of diets make the patient susceptible to IBD or increase the chances of acute crises.
