Background: While headache disorders are linked to low physical activity levels, the impact of depression on this relationship is unclear.

Objective: To assess how single and comorbid diagnoses of migraine and tension-type headache (TTH) interact with depression and leisure-time physical activity (LTPA) levels in The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

Methods: In this cross-sectional analysis based on the ELSA-Brasil baseline data, the relationship of migraine, TTH (both assessed with the International Classification of Headache Disorders, Second Edition), and depression (assessed with the Clinical Interview Schedule-Revised) with LTPA levels (International Physical Activity Questionnaire) was investigated by employing linear regression models.

The main objective was to perform a description of the potential biobehavioral factors that influence disability in patients with migraines and develop a multimodal physiotherapy treatment proposal incorporating therapeutic education and exercise prescription, applying a biobehavioral approach. This manuscript highlights the complex interplay between migraines and physical activity, with many migraine sufferers performing reduced physical activity, even during headache-free intervals. The kinesiophobia present in a significant portion of patients with migraine exacerbates functional disability and compromises quality of life.

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.

Article Synopsis
  • Researchers studied strokes from 1990 to 2021 to understand how many people get them and how they are affected around the world.
  • In 2021, strokes caused about 7.3 million deaths and were a major cause of health problems, especially in specific regions like Southeast Asia and Oceania.
  • There are differences in stroke risks based on where people live and their age, and some areas actually saw more strokes happening since 2015.

The association of thyroid function with essential and non-essential amino acids is understudied, despite their common metabolic roles. Thus, our aim was to evaluate the association of thyroid function with the levels of branched-chain amino acids (BCAAs-leucine, isoleucine, and valine) and of alanine in the general population. We utilized data from the São Paulo research center of ELSA-Brasil, a longitudinal population-based cohort study.

Article Synopsis
  • The discovery of RNA interference in 1998 led to the creation of siRNA drugs, including Patisiran, which targets a rare genetic disease called hereditary transthyretin amyloidosis.
  • Additional siRNA medications like Givosiran and inclisiran have shown positive results in treating genetic disorders and hypercholesterolemia, respectively, with ongoing research on their broader health impacts.
  • New siRNA therapies are being explored for cardiovascular conditions, aiming to reduce risk factors like lipoprotein(a) and angiotensinogen levels, with a hopeful outlook for their effectiveness in improving heart health and long-term safety in larger populations.

Introduction: Food intake biomarkers are used to estimate dietary exposure; however, selecting a single biomarker to evaluate a specific dietary component is difficult due to the overlap of diverse compounds from different foods. Therefore, combining two or more biomarkers can increase the sensitivity and specificity of food intake estimates.

Objective: This study aimed to evaluate the ability of metabolite panels to distinguish between self-reported fruit consumers and non-consumers among participants in the Longitudinal Study of Adult Health.

Article Synopsis
  • A group called the EAT-Lancet Commission created a healthy eating plan to help people and the planet, but it wasn't clear how it affects our thinking as we get older.
  • A study looked at over 11,700 people in Brazil and found that following this healthy eating plan helped slow down memory loss, especially for those with higher income.
  • Results showed that people with more money had a better chance of keeping their memory sharp, so it’s important to think about how income affects how well people can follow healthy diets.

Article Synopsis
  • Coronary artery calcification (CAC) is linked to heart disease and assessed through a genome-wide association study (GWAS) involving 22,400 participants from various backgrounds.
  • The study confirmed connections with four known genetic loci and discovered two new loci related to CAC, with supportive replication findings for both.
  • Functional tests suggest that ARSE promotes calcification in vascular smooth muscle cells and its variants may influence CAC levels, identifying ARSE as a key target for potential treatments in vascular calcific diseases.
