[Methodology and social, demographic, cognitive, and frailty profiles of community-dwelling elderly from seven Brazilian cities: the FIBRA Study].

A study was designed to identify conditions of frailty in relation to social, demographic, health, cognitive, functional, and psychosocial variables in community-dwelling elderly. The article presents the methodology and preliminary data. A total of 3,478 elderly (65 years and older) were selected from probabilistic samples of seven Brazilian cities chosen by convenience and participated in a data collection session in a community setting.

Influence of the interaction between environmental quality and T102C SNP in the HTR2A gene on fibromyalgia susceptibility.

Objectives: This study aimed to investigate the genetic influence of the T102C polymorphism of the 2A serotonin receptor gene (HTR2A) and its interaction with environmental aspects, such as exposure to noise, traffic, climate, and opportunities to acquire new information, physical protection, and security, among others, as possible risk factors for developing fibromyalgia syndrome (FMS).

Methods: Forty-one FMS patients and 49 controls were evaluated. Environmental factors were evaluated by application of the V domain of the WHOQOL-100 questionnaire.

Association between environmental quality, stress and APOE gene variation in fibromyalgia susceptibility determination.

Introduction: Fibromyalgia is a multifactorial disease, of which etiology is based on interaction between genetic susceptibility and environment. However, few studies attempted to identify the risk factors.

Objective: To investigate the genetic influence and its interaction with environmental quality and stress, as possible risk factors for fibromyalgia development.
