Sexual Orientation-Motivated Violent Victimizations in Brazil: Using Representative Data From the 2019 National Health Survey.

Using representative data from the 2019 National Health Survey (PNS-2019), we aim to investigate whether violent physical and sexual victimization differs by sexual orientation in Brazil. This was a cross-sectional study using data from a nationwide household-based survey. The PNS sample was selected with a three-stage cluster sampling.

Using Respondent-Driven Sampling (RDS) to Identify the Healthcare Needs among Women of Reproductive Age Who Migrated from Venezuela to Brazil, 2018-2021.

In 2021, an RDS survey was conducted among Venezuelan migrant women of reproductive age who migrated to two Brazilian cities (Manaus and Boa Vista) from 2018 to 2021. To start the RDS recruitment, we chose seeds non-randomly in both cities. The study variables were age, educational level, self-rated health, pregnancy, migratory status and use of health services.

HIV/Aids and COVID-19 in Brazil: in four decades, two antithetical approaches to face serious pandemics.

In the space of four decades, Brazil has faced two serious pandemics: human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and Coronavirus disease 2019 (COVID-19). The country's response to HIV/AIDS was coordinated by several stakeholders and recognised the importance of scientific evidence in guiding decision-making, and a network offering monitoring and antiretroviral treatment was provided through coordinated efforts by the country's universal health system. Conversely, the lack of a centrally coordinated strategy and misalignment between government ministries regarding the COVID-19 pandemic response, together with the denial of scientific evidence, promotion of ineffective treatments and insufficient vaccination efforts, have all led to the uncontrolled spread of infection, the near-total collapse of the health system and excess deaths.

Effect of maternal Tdap on infant antibody response to a primary vaccination series with whole cell pertussis vaccine in São Paulo, Brazil.

Background: Maternal Tetanus, diphtheria, and acellular pertussis (Tdap) vaccination provides antibody transfer to newborn infants and may affect their antibody response to the primary vaccination series. This study aimed to assess the effect of Tdap vaccination during pregnancy on infant antibody response to the whole cell pertussis (DTwP) primary series.

Methods: Plasma from 318 pregnant women (243 Tdap-vaccinated and 75 unvaccinated) and their infants (cord blood) was collected at delivery; infant blood was again collected at 2 and 7 months, before and after their primary DTwP series.

Results of the 201 mothers included in the study, 48 (23.

Association between the timing of maternal vaccination and newborns' anti-pertussis toxin antibody levels.

Background: Pertussis remains an important global public health concern, despite the presence of extensive immunization programs. Incidence and severity of pertussis are typically higher in neonates and young infants. As a strategy to protect these young infants, maternal vaccination with Tdap (tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis) has been recommended in Brazil.

The effectiveness of maternal pertussis vaccination in protecting newborn infants in Brazil: A case-control study.

Introduction: In 2014, the Brazilian Ministry of Health (MoH) recommended Tdap to pregnant women in response to a significant increase in the incidence of pertussis among infants. The present study assessed the effectiveness of maternal immunization in preventing pertussis in infants.

Methods: An unmatched case-control study was undertaken in São Paulo State, Brazil from February 2015 to July 2016.

Use of cerebrospinal fluid and serum samples impregnated on FTATM Elute filter paper for the diagnosis of infections caused by Neisseria meningitidis, Streptococcus pneumoniae and Haemophilus influenzae.

Background: The lack of information regarding the burden of acute bacterial meningitis in Latin America leads to a reduction in the estimated incidence rates of the disease, and impairs public health decisions on the use and follow-up of preventive interventions, particularly, the evaluation of existing vaccination policies. The use of the real-time PCR in diagnostic routine procedures has resulted in a substantial increase in confirmed bacterial meningitis cases. However, in resource-poor countries, these assays are only available in reference laboratories.

Homeopathic Treatment of Overweight and Obesity in Pregnant Women With Mental Disorders: A Double-blind, Controlled Clinical Trial.

Context • Worldwide, 35 million people suffer from obesity. Mental disorders have been associated with being overweight or obese. Considerable evidence has shown a correlation between stress and the use of homeopathy and stress and obesity.

Pre-exposure and postexposure prophylaxes and the combination HIV prevention methods (The Combine! Study): protocol for a pragmatic clinical trial at public healthcare clinics in Brazil.

Introduction: Few results from programmes based on combination prevention methods are available. We propose to analyse the degree of protection provided by postexposure prophylaxis (PEP) for consensual sexual activity at healthcare clinics, its compensatory effects on sexual behaviour; and the effectiveness of combination prevention methods and pre-exposure prophylaxis (PrEP), compared with exclusively using traditional methods.

Methods And Analysis: A total of 3200 individuals aged 16 years or older presenting for PEP at 5 sexually transmitted disease (STD)/HIV clinics in 3 regions of Brazil will be allocated to one of two groups: the PEP group-individuals who come to the clinic within 72 h after a sexual exposure and start PEP; and the non-PEP group-individuals who come after 72 h but within 30 days of exposure and do not start PEP.

Spatial distribution of the human development index, HIV infection and AIDS-Tuberculosis comorbidity: Brazil, 1982-2007.

Introduction: AIDS epidemic has given visibility to the incidence of tuberculosis, for being the most frequent opportunistic infection. It is known that individuals who are socially vulnerable are more susceptible to HIV transmission and tuberculosis as well.

Objective: This study aims to conduct a geoepidemiological study on HIV/AIDS, AIDS-Tuberculosis co-infection and social vulnerability.

The HIV-Brazil cohort study: design, methods and participant characteristics.

Background: The HIV-Brazil Cohort Study was established to analyze the effectiveness of combination antiretroviral therapy (cART) and the impact of this treatment on morbidity, quality of life (QOL) and mortality. The study design, patients' profiles and characteristics of cART initiation between 2003 and 2010 were described.

Methodology/principal Findings: Since 2003, the HIV-Brazil Cohort has been following HIV-infected adults receiving cART at 26 public health care facilities, using routine clinical care data and self-reported QOL questionnaires.

Temporal trends and molecular epidemiology of HIV type 1 infection in Rio de Janeiro, Brazil.

HIV-1 molecular epidemiology studies carried out in Rio de Janeiro, Brazil have identified the prevalence of subtypes B, F1 and BF1 recombinants. A high percentage of HIV-1 subtype B isolates in Rio de Janeiro harbor the GWG motif at the V3 tip (B'' variant) instead of the canonical GPG motif (B variant). To trace the dynamics of the HIV-1 variants over time in different exposure categories in Rio de Janeiro, the HIV-1 proviral DNA from heterosexual men (HET) and men who have sex with men (MSM) from two distinct time periods (1990-1992 and 2008-2010) were extracted, and the env-gp120 region was amplified.

Self-rated health by HIV-infected individuals undergoing antiretroviral therapy in Brazil.

In 2008, a survey was applied to a probabilistically selected sample of 1,245 HIV-infected patients on antiretroviral therapy in Brazil. In this work, the analysis was focused on self-rated health. The analysis was conducted according to sex, age, socioeconomic variables, and clinical and treatment-related patient characteristics.

Evaluation of strategies by the Brazilian Ministry of Health to stimulate the municipal response to AIDS.

The aim of this study was to evaluate strategies by the Brazilian Ministry of Health to expand the municipal response to AIDS. Cities "included" and "not included" in Federal strategies for "municipalization" of the response were compared according to the response profile and trends in the epidemic. Multinomial logistic regression was used, among other statistical procedures.

[Professional background and experience of antiretroviral prescribing physicians in the State of São Paulo].

Objective: Analysis of the professional profile of physicians who prescribe antiretroviral drugs (ARV) to HIV infected persons in the State of São Paulo.

Methods: Databases from different sources, namely Ministry of Health, São Paulo State Regional Medical Council, National Commission on Medical Residency and the Lattes platform, were consulted. Data concerning socio-demographic characteristics, academic and professional background and experience for the period from October 2007 to May 2009 were analyzed.

[The AIDS epidemic in Brazil and differences according to geographic region and health services supply].

The aim of this study was to identify different profiles in the AIDS epidemic in Brazil by relating them to the health sector's organization, situations involving increased risk of infection, and the degree of implementation of the response by health services. The Brazilian municipalities (counties) were grouped according to the magnitude of the epidemic and its trends from 2002 and 2006, and were then studied using indicators obtained from secondary databases. Municipalities with large epidemics (39%) displayed more situations associated with risk of infection, and those with an upward trend in incidence (11.

[AIDS and transmissible opportunistic diseases in the Brazilian border area].

Introduction: Person-to-person transmission of HIV and other communicable diseases may be associated with human geographic mobility. This article evaluated the incidence of transmissible opportunistic diseases among AIDS cases that had been reported by municipalities in the Brazilian border area.

Methods: Brazilian border area municipalities were grouped into three cultural regions; the source data was AIDS cases registered with the Ministry of Health from 1990 to 2003, which were classified according to CDC-adapted, Rio de Janeiro/Caracas and death criteria; detected communicable opportunistic diseases were categorized into groups according to transmission: 1) inhalation agent; 2) contaminated water and/or food ingestion, and 3) interpersonal contact.

Magnitude and trend of the AIDS epidemic in Brazilian cities, from 2002 to 2006.

Objective: To analyze different patterns of occurrence of AIDS in Brazilian cities between 2002 and 2006, associating trend and magnitude with socio-demographic indicators and local characteristics of the epidemic.

Methods: This was an ecological study that categorized cities according to magnitude and trend of the epidemic and subsequently analyzed, considering social indicators, types of HIV transmission and year of first case reported. Data came from the Brazilian Epidemiological Surveillance System, the Brazilian Institute of Geography and Statistics and the United Nations Development Program for Brazil.

[The aids epidemic in the State of São Paulo: application of the full Bayesian space-time model].

The State of São Paulo accounts for approximately 40% of the AIDS cases notified in Brazil and provides a suitable opportunity for space-time analysis aimed at better understanding of the dissemination of HIV/AIDS. Using the AIDS cases notified to the Ministry of Health between 1990 and 2004, among individuals aged 15 years or over, and the Ministry of Health's information system for disease notification (Sistema de Informação de Agravos e Notificação, SINAN) as the information source, the relative risks of AIDS over three-year periods were estimated using full Bayesian models, for each gender. The models used were shown to be adequate for explaining the process of AIDS dissemination in the State of São Paulo and demonstrated the growth among females and in small-sized municipalities.
