Objective: Gender differences may interfere with the association between Negative Life Events (NLEs) and prevalent/incident depression. This study evaluated the effect of gender in this association using data from the ELSA-Brazil cohort.
Methods: The authors analyzed 15,088 participants (mean age, 52.
Article Synopsis
- The study investigates the link between antithyroperoxidase antibodies (TPOAb) and carotid intima-media thickness (cIMT) to better understand how thyroid autoimmunity relates to cardiovascular disease.
- It analyzed data from 9,264 participants without prior cardiovascular issues, finding that varying levels of TPOAb were significantly associated with increased cIMT at the initial assessment.
- However, there was no significant connection between TPOAb levels and increased cIMT at the follow-up after eight years, particularly in individuals with normal thyroid function.
Background: There is scarce data concerning the relationship between negative life events (NLEs)* and current and new depressive episodes by age.
Methods: Cross-sectional (baseline) and prospective analyses (4-year/8-year follow-ups) were performed in 15,105 civil servants in 6 cities in Brazil classified according to age strata at baseline: 1st(35-44), 2nd(45-54), 3rd(55-64), and 4th(65-74) years. The independent variable was NLEs in the last year (robbery, hospitalization, death of a relative, financial hardship, and rupture of a love relationship) collected at baseline.
Objective: The aim of this study was to investigate whether sex, age, race, income, education, and marital status are associated with having a religion in a sample of Brazilian men and women.
Methods: Data were obtained from 15,098 participants of the Brazilian Longitudinal Study of Adult Health, a longitudinal study that ultimately aims to investigate long-term outcomes of chronic diseases. The sociodemographic characteristics and data on religion status were self-reported during interviews conducted by trained personnel.
Objective: To assess the influence of two functional scales- Modified Rankin Scale (m-RS) and Modified Katz Index (m-Katz Index) on long-term mortality in a stroke cohort.
Material And Methods: Among 760 stroke survivors (median age: 66 (IQR:56-75), 56.4 % women) m-Katz Index and m-RS scales applied at 1 and 6 months after stroke, were investigated in relation to 12-years of all-cause mortality.
Background: Atrial fibrillation (AF) is a major risk factor for stroke. To enable improvements to AF diagnosis and follow-up care, understanding current patient pathways and barriers to optimal care are essential. We investigated the patient care pathways and their drivers, and the impact of the COVID-19 pandemic on patient pathways in a middle-income country setting, Brazil.

Lipsmacking behaviour, which involves at least two individuals in socially mediated interactions, may tell about processes that maintain, accentuate or attenuate emotional exchanges in monkeys. Lipsmacking is a facial expression associated with the establishment and maintenance of affiliative interactions, following under the 'emotional regulation' umbrella, which accounts for the ability to manage behavioural responses.

Objective: To describe generalisability and lessons learned from recruitment and data collection for the quantitative component of a mixed methods study designed to determine the care pathway for atrial fibrillation (AF) in Brazil, China and Sri Lanka.
Methods: Adults (≥18 years) that spoke the local language and with an AF diagnosis were eligible.
Background: The association between ideal cardiovascular health (ICVH) status and atrial fibrillation or flutter (AFF) diagnosis has been less studied compared to other cardiovascular diseases.
Objective: To analyze the association between AFF diagnosis and ICVH metrics and scores in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).
Methods: This study analyzed data from 13,141 participants with complete data.
Aim: To investigate the association between medication use and long-term all-cause mortality in a Brazilian stroke cohort.
Methods: Both ischemic and hemorrhagic stroke were evaluated. Medication use was assessed as: never, only pre-stroke, only post-stroke, and continuous use.
Objective: This study aimed to prospectively evaluate whether TSH levels at baseline were associated with incident depression after four years of follow-up in a cohort of middle-aged adults, the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).
Methods: TSH and free-thyroxine (FT4) levels were evaluated at baseline. Depression diagnoses were performed using the Clinical Interview Schedule-Revised (CIS-R) at baseline and after a 4-year follow-up.
Background: Some religious dimensions have been associated with different health-related outcomes over many years. Attending religious services is one of these dimensions that were associated with hypertension, with inconsistent results. And religious involvement seems to be closely influenced by sociodemographic factors, such as education.
