- ArtigoMasturbatory Behavior and Body Image: A Study Among Brazilian Womende Lima T.E.O.; Dissenha R.P.; Skare T.L.; Leinig C.A.S. (2022)© 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.Masturbation is a variant of sexual expression and has no known causal relation with sexual disorders. Literature is still scarce in studies addressing particularities of female masturbation and its associations. The aim of this study was to investigate female masturbation in a Brazilian sample. The objectives were also analyzing the associations and correlations between masturbation and different variables, including body image. A total of 2408 Brazilian women (mean age 27.78 years) answered a 70-item online survey based on literature review, standardized questionnaires (Female Sexual Quotient, Body Image Guilt and Shame Scale- Brazilian version and Body Appreciation Scale-2) and questions from previous studies on female masturbation. The most prevalent masturbation frequency reported was two or three times a week (29.91%), and “reduce stress” was a common motivation to engage in masturbation (48.28%). There was a positive correlation between masturbation frequency and sexual satisfaction (Rho = 0.16, p < 0.001). It was observed that higher masturbation frequency was correlated with lower body shame (Rho = − 0.06, p = 0.001) and body guilt (Rho = − 0.07, p < 0.001). Moreover, body appreciation was positively correlated with masturbation frequency (Rho = 0.10, p < 0.001). It is important noting that the present correlations were weak and do not imply a necessary cause-effect link. Masturbation has been demonstrated to be an important component of female libido, not simply a sexual partner substitute.
- ArtigoSafety and efficacy of arteriovenous fistula angioplasties performed by nephrologists: report from a Brazilian interventional nephrology center Segurança e eficácia de angioplastias de fístulas arteriovenosas realizadas por nefrologistas: relato de um centro de nefrologia intervencionista brasileiroFranco R.P.; Riella M.C.; Chula D.C.; De Alcantara M.T.; Do Nascimento M.M. (2022)© 2022 Jornal Brasileiro de Nefrologia. All rights reserved.Introduction: Arteriovenous fistulas (AVF) are the first choice vascular access for hemodialysis. However, they present a high incidence of venous stenosis leading to thrombosis. Although training in interventional nephrology may improve accessibility for treatment of venous stenosis, there is limited data on the safety and efficacy of this approach performed by trained nephrologists in low-income and developing countries. Methods: This study presents the retrospective results of AVF angioplasties performed by trained nephrologists in a Brazilian outpatient interventional nephrology center. The primary outcome was technical success rate (completion of the procedure with angioplasty of all stenoses) and secondary outcomes were complication rates and overall AVF patency. Findings: Two hundred fifty-six angioplasties were performed in 160 AVF. The technical success rate was 88.77% and the main cause of technical failure was venous occlusion (10%). The incidence of complications was 13.67%, with only one patient needing hospitalization and four accesses lost due to the presence of hematomas and/or thrombosis. Grade 1 hematomas were the most frequent complication (8.2%). The overall patency found was 88.2 and 80.9% at 180 and 360 days after the procedure, respectively. Conclusion: Our findings suggest that AVF angioplasty performed by trained nephrologists has acceptable success rates and patency, with a low incidence of major complications as well as a low need for hospitalization.
- ArtigoInfluence of mechanical power and its components on mechanical ventilation in SARS-CoV-2Franck C.L.; Franck G.M. (2022)© 2022 Associacao de Medicina Intensiva Brasileira - AMIB. All rights reserved.Objective: To analyze the influence of mechanical power and its components on mechanical ventilation for patients infected with SARS-CoV-2; identify the values of the mechanical ventilation components and verify their correlations with each other and with the mechanical power and effects on the result of the Gattinoni-S and Giosa formulas. Methods: This was an observational, longitudinal, analytical and quantitative study of respirator and mechanical power parameters in patients with SARS-CoV-2. Results: The mean mechanical power was 26.9J/minute (Gattinoni-S) and 30.3 J/minute (Giosa). The driving pressure was 14.4cmH2O, the plateau pressure was 26.5cmH2O, the positive end-expiratory pressure was 12.1cmH2O, the elastance was 40.6cmH2O/L, the tidal volume was 0.36L, and the respiratory rate was 32 breaths/minute. The correlation between the Gattinoni and Giosa formulas was 0.98, with a bias of -3.4J/minute and a difference in the correlation of the resistance pressure of 0.39 (Gattinoni) and 0.24 (Giosa). Among the components, the correlations between elastance and driving pressure (0.88), positive end-expiratory pressure (-0.54) and tidal volume (-0.44) stood out. Conclusion: In the analysis of mechanical ventilation for patients with SARS-CoV-2, it was found that the correlations of its components with mechanical power influenced its high momentary values and and that the correlations of its components with each other influenced their behavior throughout the study period. Because they have specific effects on the Gatinnoni-S and Giosa formulas, the mechanical ventilation components influenced their calculations and caused divergence in the mechanical power values.
- ArtigoFertility Does not Quarantine: Coronavirus Disease 2019 Pandemic Impacts on in Vitro Fertilization Clinical Pregnancy RatesDe Almeida Vieira F.; Neto R.P.; Morila M.C.G.; Curimbaba J.B.; Pasquini D.S.; Felchner P.C.Z.; Wandresen G.; Pachnicki J.P.A. (2022)© 2022 Georg Thieme Verlag. All rights reserved.Objective To understand the impact of the coronavirus disease 2019 pandemic on in vitro fertilization (IVF) clinical pregnancy rates and analyze factors that may have influenced their outcome. Methods This was a retrospective observational study conducted at a tertiary-care Brazilian fertility center. All fresh IVF and embryo warming cycles performed from March 11 to December 31, 2018-2021 were analyzed, and their data were used to calculate fertilization, embryo cleavage, cycle cancellation, embryo transfer (ET), and clinical pregnancy rates. Statistical tests were used to evaluate the alterations found. Logistic regression models were used to explore the association of the categorical variables with the observed clinical pregnancy rates. Data from 2018 and 2019 (prepandemic) and 2020 and 2021 (pandemic) were grouped. Results A total of 756 cycles were analyzed (n = 360 prepandemic and n = 396 pandemic). The age group of the patients, fertilization rates, and cleavage rates did not have significant differences (p > 0.05). There was a reduction in the percentage of fresh IVF and an increase in embryo warming cycles (p = 0.005) during the pandemic. There was also an increase in fresh cycle cancellations (p < 0.001) and a reduction in ET rates (p < 0.001). The pandemic had a negative impact on clinical pregnancy rates (p < 0.001) especially due to the increase in fresh cycle cancellations (p < 0.001). Conclusion Embryo warming cycles with subsequent frozen-thawed ET were presented as a viable alternative to continue assisted reproductive treatments against pandemic restrictions on fresh cycles, ensuring clinical pregnancy, albeit at a lower rate than that of the prepandemic period.
- ArtigoYellow fever virus investigation in tissues of vampire bats Desmodus rotundus during a wild yellow fever outbreak in Brazilian Atlantic ForestCupertino M.D.C.; Bayao T.D.S.; Xisto M.F.; Paula S.O.; Ribeiro S.P.; Montenegro S.S.P.; Freitas M.B.; Gomes A.P.; Siqueira-Batista R. (2022)© 2022 Elsevier LtdIn the last decade a large outbreak of Yellow Fever (YF) has been observed in Brazilian Atlantic Forest region, traditionally a non-endemic area. In this scenario, the role of wild mammal species as YF reservoirs can be questioned, especially the hematophagous bat, Desmodus rotundus. So, the objective of this study was to analyze molecularly the presence of the YF virus (YFV) in hematophagous bats during a YF outbreak in Brazil. Twenty-one samples were collected from seven adult male hematophagous bats D. rotundus. As YFV is considered a viscerotropic and neurotropic virus, samples of liver, kidney and brain were collected and molecularly analyzed using the RT qPCR technique. The animals were captured according to ethical protocols during a YF outbreak in Brazil in 2017, from a region of the Brazilian Atlantic Forest. The results revealed that the analyzed tissue samples were not infected with the YFV. The negative results for this bat species allow us to infer that other animals may be reservoirs of this virus in this ecosystem and they probably have not been identified yet. Therefore, health surveillance actions are essential to monitor the role of wild animals in the YF dissemination in Brazilian Atlantic Forest and alert to the possibility of new geographic amplification of areas where YF occurs. This research encourages the new search about the role of wild animals on YFV transmission and reinforces the importance of epidemiological surveillance in the transmission of human infectious diseases.
