Heart rate turbulence analysis in female patients with fibromyalgia.

OBJECTIVE: Fibromyalgia is characterized by diffuse musculoskeletal pain and discomfort. There are several reports regarding autonomic nervous system dysfunction in patients with fibromyalgia. Heart rate turbulence is expressed as ventriculophasic sinus arrhythmia and has been considered to reflect cardiac autonomic activity. Heart rate turbulence has been shown to be an independent and powerful predictor of sudden cardiac death in various cardiac abnormalities. The aim of this study is to determine whether heart rate turbulence is changed in female patients with fibromyalgia compared with healthy controls. METHODS: Thirty-seven female patients (mean age, 40±11 years) with fibromyalgia, and 35 age- and sex-matched healthy female control subjects (mean age, 42±9 years) were included. Twenty-four hours of ambulatory electrocardiography recordings were collected for all subjects, and turbulence onset and turbulence slope values were automatically calculated. RESULTS: The baseline clinical characteristics of the two groups were similar. There were no significant differences in turbulence onset and turbulence slope measures between patients and control subjects (turbulence onset: -1.648±1.568% vs. -1.582±1.436%, p ϝ 0.853; turbulence slope: 12.933±5.693 ms/RR vs. 13.639±2.505 ms/RR, p ϝ 0.508). Although body mass index was negatively correlated with turbulence slope (r ϝ -0.258, p ϝ 0.046), no significant correlation was found between body mass index and turbulence onset (r ϝ 0.228, p ϝ 0.054). CONCLUSION: To the best of our knowledge, this is the first study to evaluate heart rate turbulence in patients with fibromyalgia. It appears that heart rate turbulence parameters reflecting cardiac autonomic activity are not changed in female patients with fibromyalgia.

The effects of attention deficit hyperactivity disorder on clothing selection and habits among Turkish University students.

The purpose of this study was to identify the factors that influence the shopping attitudes of college students with and without ADHD. This study also examined the effects of ADHD on the academic and social lives of college students. The sample consisted of 219 university students. These students were interviewed by a psychiatrist with regard to ADHD symptoms according to the DSM-IV. The Adult ADHD Self Report Scale (ASRS), the Teen Interpersonal Influence Scale, and a demographic information form were used as measurement devices. The ADHD and control groups were classified in three different ways: (1) met the ADHD criteria for both Clinical Diagnosis and the ASRS; (2) met only the criteria for Clinical Diagnosis; or (3) met only the criteria of the ASRS. Our research shows that individuals with ADHD experience more problems with money management and are more affected by the media, friends, and brands compared with individuals without ADHD. Smoking and alcohol use disorders, accidents, being held back, and disciplinary actions often accompany ADHD in college students. To the best of our knowledge, the shopping attitudes of young adults with ADHD and the influence of the media, peers, family, and brands have not been studied until now.
