Protocol for an ambidirectional cohort study on long COVID and the healthcare needs, use and barriers to access health services in a large city in Southeast Brazil.

Introduction: Post-COVID-19 condition, or syndrome, also known as long COVID, is an infection-associated chronic condition that can develop after a SARS-CoV-2 infection and last at least 3 months to years. Despite representing a high burden for the Unified Health System (SUS), which has affected millions of Brazilians, it has received limited attention in Brazil. Prevalence studies to date have failed to include a broad representation of the population, and there has been insufficient exploration of the impact on people's lives and the burden of and barriers to accessing health services.

Polysubstance use in a Brazilian national sample: Correlates of co-use of alcohol and prescription drugs.

: Responses to problem substance use have largely focused on illicit drugs, but reports on rising prescription drug misuse worldwide raise questions about their combined use with alcohol and potential consequences. The current study assessed prevalence of alcohol in conjunction with nonmedical opioid and benzodiazepine use across a nationally representative sample of adults in Brazil. Cross-sectional data on prevalence were estimated from the 2015 Brazilian Household Survey on Substance Use.

Substance use, self-rated health and HIV status in Brazil.

We compared the prevalence of of non-injecting drug use (NIDU) and Self-Rated Health (SRH) among individuals self-reporting as HIV-positive (PLWHA), HIV-negative and unknown at the III Brazilian Household Survey on Substance Use. Overall, 16,273 individuals, 12-65 years old, were interviewed in 2015. Prevalence and Standard Error (SE) were estimated considering the complex sample design and weight calibration.

Factors associated with low handgrip strength in older people: data of the Study of Chronic Diseases (Edoc-I).

Background: Handgrip strength (HGS) is an important health biomarker whose low scores have been shown to be associated with the morbimortality. This study aimed to analyze the factors associated with low HGS in older people in Rio Branco, Acre, Brazil.

Methods: The study was carried out with data from the Study of Chronic Diseases (EDOC-I) - Older People, a cross-sectional household PAPI probability sample survey performed with 1016 people aged over 60 residing in Rio Branco in 2014.

Reproducibility on science: Challenges and advances in Brazilian alcohol surveys.

Background: Reproducibility in Science is challenging and may be hard to achieve in alcohol research. Previous general population surveys in Brazil have estimated the prevalence of alcohol dependence to be around 10%. We aim to estimate alcohol use and dependence using different methods and definitions.

Factors associated with PrEP awareness according to age and willingness to use HIV prevention technologies: the 2017 online survey among MSM in Brazil.

Brazil has the largest population of individuals living with HIV/AIDS in Latin America with a disproportional prevalence of infection among men who have sex with men (MSM). This study evaluated PrEP awareness by age (18-24, 25-35, ≥36 years), its associated factors and the willingness to use HIV prevention technologies among MSM using a GSN app in Brazil. Inclusion criteria were ≥18 years-old, cisgender men and HIV-negative serostatus.

Syndemics among individuals enrolled in the PrEP Brasil Study.

Background: Concurrent psychosocial problems may synergistically increase the risk of HIV infection (syndemics), representing a challenge for prevention. We aimed to evaluate the prevalence and associated factors of syndemics among men who have sex with men (MSM) and transgender women (TGW) enrolled in the Brazilian pre-exposure prophylaxis demonstration study (PrEP Brasil Study).

Methods: Secondary cross-sectional analysis of the PrEP Brasil Study was performed.

Health care factors associated with survival among women with breast cancer on hormone therapy in Rio de Janeiro, Brazil, 2004 - 2010.

Objectives To better understand the role that health care plays in breast cancer survival by investigating the effects that hormone therapy adherence and other select health care variables, adjusted for clinical and sociodemographic factors, had among a population of women in Rio de Janeiro, Brazil. Methods This was a longitudinal study based on secondary data of 5 861 women treated with hormone therapy (tamoxifen or aromatase inhibitors) at the National Cancer Institute of Brazil (INCA), from 1 January 2004 - 29 October 2010. Four different sources of data were integrated for analysis: INCA Pharmacy Sector Dispensation System; Hospital-based Cancer Registry; Integrated Hospital System and INCA Absolute System; and Mortality Information System.

[Macronutrient food sources in a probabilistic sample of Brazilian adults].

Once it is available, the information on food intake (FI) may enable the development of strategies to intervene, monitor and explore dietary patterns with more sophisticated statistical methods. Thus, the purpose of this study was to document the quantitative dietary characteristics in a probabilistic sample of adults in Niterói in the State of Rio de Janeiro. A 24-hour dietary recall of a typical day was conducted.

Adherence to hormone therapy among women with breast cancer.

Background: Despite the excellent results obtained with hormone therapy, the long treatment period and the side effects associated with its use make patient adherence difficult. Moreover, certain aspects of health care can mitigate or exacerbate non-adherence. This study aimed to identify the factors associated with adherence to hormone therapy for breast cancer, with the goal of contributing to the reformulation of the care process and to improvements in outcomes.

[Regulation of radiotherapy and chemotherapy services by health plan organizations in Brazil].

This paper characterizes regulatory procedures applied by private health plan operators on their outpatient radiotherapy and chemotherapy services, especially via contracts, and outlines the health care providers’ perception on regulation. The study relied on primary data, taking into consideration 638 hospitals and outpatient health care units with the services in question. A stratified random sample was selected, resulting in the inclusion of 54 units that are representative of the population, excluding hospitals that only provide radiotherapy.

Is the prevalence of driving after drinking higher in entertainment areas?

Aims: This study aimed to estimate the prevalence of driving after drinking (DUI) and its associated factors in low and high alcohol outlet density areas (LAOD and HAOD) in Porto Alegre, Brazil.

Methods: A probability 3-stage sampling survey was conducted, and 683 drivers who were leaving alcohol outlets (AOs) and had been drinking were interviewed, breathalyzed and saliva was collected for drug screening.

[Evaluation of the pre-test counseling process in the HIV Testing and Counseling Centers in Rio de Janeiro State: the perception of users and health professionals].

This study sought to evaluate the pre-test counseling process in the HIV Testing and Counseling Centers (CTA) in Rio de Janeiro State, based on the perceptions of users and health professionals. A population survey was performed, based on a structured questionnaire given to a sample of users and counselors of nine CTAs. Quantitative analyses were employed to evaluate the degree of satisfaction in relation to infrastructure indicators of the way patients are received and treated, the user-counselor relationship, and territoriality, accessibility and availability.

Reaching the hard-to-reach: a probability sampling method for assessing prevalence of driving under the influence after drinking in alcohol outlets.

Drinking alcoholic beverages in places such as bars and clubs may be associated with harmful consequences such as violence and impaired driving. However, methods for obtaining probabilistic samples of drivers who drink at these places remain a challenge--since there is no a priori information on this mobile population--and must be continually improved. This paper describes the procedures adopted in the selection of a population-based sample of drivers who drank at alcohol selling outlets in Porto Alegre, Brazil, which we used to estimate the prevalence of intention to drive under the influence of alcohol.
