ABSTRACT

BACKGROUND/AIMS: To assess the technical feasibility and outcomes of femtosecond laser-assisted Bowman layer transplantation (FLABOLT) in stabilizing progressive, advanced keratoconus, which is ineligible for corneal crosslinking. METHODS: This single-center retrospective study included 50 eyes of 49 patients with progressive advanced keratoconus, ineligible for corneal crosslinking, that underwent FLABOLT with both the donor graft and recipient mid-stromal pocket using a femtosecond laser. RESULTS: The mean follow-up was 13.2 ± 4.9 months (range 7-35 months). Donor graft preparation and accurate dissection of the recipient mid-stromal pocket were successful in 96% and 100% of cases, respectively. The mean maximum keratometry decreased by 1.93 D at 6 months after surgery and there was no change in the mean preoperative best contact lens-corrected visual acuity (BCLVA). Three eyes developed hydrops postoperatively and recovered after clinical treatment. One eye that achieved useful BCLVA postoperatively, worsened 2 years after the surgery due to progressive corneal scarring and required corneal transplantation for visual rehabilitation. Preoperative corneal scarring was a risk factor for BCLVA loss. All other eyes remained stable (92%), and no other procedure was required until the last follow-up. CONCLUSION: In this series, FLABOLT was successfully performed as an alternative to stabilize advanced progressive keratoconus. This technique is highly reproducible for graft preparation and recipient pocket dissection when assisted by femtosecond laser. Despite promising initial results, more studies with longer follow-up periods are needed to evaluate the effectiveness of FLABOLT in stabilizing advanced progressive keratoconus.

ABSTRACT

This study aimed to evaluate the influence of bareback sexually explicit media (SEM) consumption on anal sex without a condom by men who have sex with men (MSM). To this end, a page was created on the Facebook® social network with a link that directed interested parties to a questionnaire. Cisgender men, aged 18 years and over, who had sex with other men in the last 12 months, were included. Data were collected in 2017 and analyzed using univariate and bivariate inferential statistics and multivariate logistic regression. A total of 2,248 MSM participated in the research, with a mean age of 24.4 years and a mean number of 3.9 partners in the last 30 days. Having multiple sexual partners (ORa: 9.4; 95% CI 3.9-22.4), preferring movies with bareback scenes (ORa: 2.6; 95% CI 1.5-4.6), considering this practice a fetish and realizing it (ORa: 3.52; 95% CI 2.3-5.4), having casual partnerships (ORa: 1.8; 95% CI 1.5-1.9) and being aware of the partner's negative serological status for HIV (ORa: 1.4; 95% CI 1.1-2.3) were factors that increased the likelihood of engaging in anal sex without a condom. Thus, we found an association between the consumption of bareback SEM and sex without a condom among MSM.

ABSTRACT

In the current pandemic situation raised due to COVID-19, drug reuse is emerging as the first line of treatment. The viral agent that causes this highly contagious disease and the acute respiratory syndrome coronavirus (SARS-CoV) share high nucleotide similarity. Therefore, it is structurally expected that many existing viral targets are similar to the first SARS-CoV, probably being inhibited by the same compounds. Here, we selected two viral proteins based on their vital role in the viral life cycle: Structure of the main protease SARS-CoV-2 and the structural base of the SARS-CoV-2 protease 3CL, both supporting the entry of the virus into the human host. The approved drugs used were azithromycin, ritonavir, lopinavir, oseltamivir, ivermectin and heparin, which are emerging as promising agents in the fight against COVID-19. Our hypothesis behind molecular coupling studies is to determine the binding affinities of these drugs and to identify the main amino acid residues that play a fundamental role in their mechanism of action. Additional studies on a wide range of FDA-approved drugs, including a few more protein targets, molecular dynamics studies, in vitro and biological in vivo evaluation are needed to identify combination therapy targeted at various stages of the viral life cycle. In our experiment in silico, based mainly on the molecular coupling approach, we investigated six different types of pharmacologically active drugs, aiming at their potential application alone or in combination with the reuse of drugs. The ligands showed stable conformations when analyzing the affinity energy in both proteases: ivermectin forming a stable complex with the two proteases with values -8.727 kcal/mol for Main Protease and -9.784 kcal/mol for protease 3CL, Heparin with values of -7.647 kcal/mol for the Main protease and -7.737 kcal/mol for the 3CL protease. Both conform to the catalytic site of the proteases. Our studies can provide an insight into the possible interactions between ligands and receptors, through better conformation. The ligands ivermectin, heparin and ritonavir showed stable conformations. Our in-silica docking data shows that the drugs we have identified can bind to the binding compartment of both proteases, this strongly supports our hypothesis that the development of a single antiviral agent targeting Main protease, or 3CL protease, or an agent used in combination with other potential therapies, it could provide an effective line of defense against diseases associated with coronaviruses.

ABSTRACT

The aim of this study was to evaluate the influence of sexually explicit media (MSE) consumption of the "bareback" type in the practice of anal sex without a condom by men who have sex with men (MSM). To this end, a Facebook® page was created, with a link that directed participants to the study questionnaire. Users who identified themselves as cisgendered men, aged 18 or over and who had sex with another man in the 12 months prior to the survey were included. Data were collected in 2017 across Brazil and analyzed using univariate and bivariate inferential statistics and multivariate logistic regression. 2248 MSM participated in the research, with a mean age of 24.4 years. Most were single (69.1%), with casual sexual partner (68.9%) and an average of 3.9 partners in the last 30 days. Have multiple sexual partners (ORa: 9.4; 95% CI 3.9-22.4), prefer films with bareback scenes (ORa: 2.6; 95% CI 1.5-4.6), judge this practice a fetish and perform it (ORa: 3.52; 95% CI 2.3-5.4), have casual partnership (ORa: 1.8; 95% CI 1.5-1.9) and awareness of the partner's negative serological status for HIV (ORa: 1.4; 95% CI 1.1-2.3) were factors that increased the chances of engaging in anal sex without a condom. Thus, we verified an association between the consumption of MSE in the "bareback" modality and the practice of sex without a condom among MSM.

ABSTRACT

We started a study on the molecular docking of six potential pharmacologically active inhibitors compounds that can be used clinically against the COVID-19 virus, in this case, remdesivir, ribavirin, favipiravir, galidesivir, hydroxychloroquine and chloroquine interacting with the main COVID-19 protease in complex with a COVID-19 N3 protease inhibitor. The highest values of affinity energy found in order from highest to lowest were chloroquine (CHL), hydroxychloroquine (HYC), favipiravir (FAV), galidesivir (GAL), remdesivir (REM) and ribavirin (RIB). The possible formation of hydrogen bonds, associations through London forces and permanent electric dipole were analyzed. The values of affinity energy obtained for the hydroxychloroquine ligands was -9.9 kcal/mol and for the chloroquine of -10.8 kcal/mol which indicate that the coupling contributes to an effective improvement of the affinity energies with the protease. Indicating that, the position chosen to make the substitutions may be a pharmacophoric group, and cause changes in the protease.

ABSTRACT

Os autores tecem considerações sobre a militância no campo da saúde, em especial na defesa do Sistema Único de Saúde (SUS), enquanto uma política pública universal. Após apontar algumas estratégias desta militância, o texto discute o centralismo e o caráter identitário dessas práticas. Destacam e problematizam quatro formas de centralismo: do "bem comum" em suas representações; o procedimento como oferta de tecnologias de saúde; do usuário e as concepções sobre suas necessidades/demandas; e da proteção inadvertida da vida. Propõem, como alternativa, uma nova militância no SUS, como prática intensiva e produzida no encontro, na dimensão relacional, entre gestores, trabalhadores e usuários.


The authors make comments about militancy in the field of healthcare, especially for defending the Brazilian Unified Health System (SUS) as a universal public policy. After indicating some strategies for such militancy, the text discusses centralism and the identifying nature of these practices. It highlights and questions four forms of centralism: the "common good" in its representations; procedures as offers of health technologies; users and notions about their needs/demands; and careless protection of life. As an alternative, the authors propose a new form of militancy within SUS, as intensive practice produced at the meeting point within the dimension of the relationship between managers, workers and users.

ABSTRACT

Tendo como ponto de partida o surgimento do Manual Diagnóstico e Estatístico de Transtornos Mentais (DSM-III) a partir da década de 1980, marco das transformações na clínica psiquiátrica, o autor procura analisar a relação entre os discursos e práticas da psiquiatria Biológica e seus efeitos no processo de produção da subjetividade. Tomando como referência a tese foucaultiana de que a medicina é uma estratégia biopolítica, procuramos mostrar o processo de gestão do corpo e medicalização da saúde como formas de controle que encarnam o biopoder na contemporaneidade.


Having as a start the emergence of the Diagnostic and Statistical Manual of Mental Disorder (DSM-III) in the 80's, mark of transformations in psychiatric clinic, the author aims to analyze the relationship between discourses and practices of the Biological Psychiatry and their effects in production and subjectivity processes. Taking as reference Foucault's theory which states that medicine is a biopolitic strategy, we intended to describe the process of body management and medicalization of health as controlling forms which represent biopower nowadays.

ABSTRACT

O objetivo desta dissertação foi cartografar os modos de funcionamento dos discursos e práticas que produzem a Psiquiatria Biológica como um dispositivo do biopoder. Procuramos situar sua emergência como um efeito das transformações da sociedade capitalista que, a partir da segunda metade do século XX, passa a constituir a realidade através de novos modos de funcionamento, culminando com a chamada pós-modernidade. Para nos debruçarmos sobre esta influência recíproca entre a biopolítica e a clínica psiquiátrica, investigamos o modo de operar da prática diagnóstica, através da relação entre marcadores biológicos e exames laboratoriais, procurando mostrar o processo de gestão do corpo e medicalização da saúde como formas de controle que encarnam o biopoder na contemporaneidade. Para tanto, buscando pensar o exercício deste dispositivo do biopoder, nos servimos da força intercessora dos conceitos filosóficos de Michel Foucault e Gilles Deleuze. No percurso desenvolvido, procuramos situar as relações entre a medicina mental e as tecnociências, mostrando os efeitos desta biopolítica no processo de produção da saúde e subjetividade. Em contraposição ao discurso da psiquiatria biológica, concluímos discutindo a necessidade de uma reorganização teórico-prática de resistência à medicalização da vida cotidiana propondo a produção de uma biopolítica em favor das potencialidades de criação de outros modos de subjetivação.
