Possible influences of vitamin D levels on sleep quality, depression, anxiety and physiological stress in patients with chronic obstructive pulmonary disease: a case control study.

This study aimed to evaluate the effect of vitamin D deficiency on sleep quality, depression, anxiety, and physiological stress in patients with chronic obstructive pulmonary disease (COPD). We screened for COPD patients with normal (NorVD) (n=24) and insufficient (InsVD) (n=7) vitamin D levels. The Pittsburgh sleep quality index (PSQI), the Beck anxiety inventory (BAI), the Beck depression inventory (BDI) and the Baevsky's stress index were used for the sleep and psychometric evaluation.

Correlation of sleep quality and cardiac autonomic modulation in hemodialysis patients.

Objectives: Sleep disorders in patients on hemodialysis are frequent, but few studies correlate these disorders with autonomic dysfunction in these patients. This study aimed to verify whether clinical and laboratory variables and heart rate variability are associated with worse sleep quality verified by the Pittsburg subjective scale in patients on hemodialysis.

Material And Methods: A cross-sectional study was performed on forty-eight patients.

Phenotypes of mutations related to voltage-dependent sodium channels on children and adolescents.

Cardiac channelopathies are a heterogeneous group of inherited cardiac diseases that are associated with mutations in the genes that encode the expression of cardiac ion channels. In view of this, it can be mentioned that the main hereditary arrhythmias in children and adolescents, caused by dysfunction of the ion channels, are Brugada Syndrome (BrS) and Long QT Syndrome (LQTS). However, few studies address the physiological effects of these conditions on children and adolescents.

Carvacrol reduces blood pressure, arterial responsiveness and increases expression of MAS receptors in spontaneously hypertensive rats.

Aim: To analyze the effect of the use of carvacrol in the cardiovascular system of spontaneously hypertensive rats (SHR).

Methods: Methods: Twenty animals were allocated in four groups, one group control Wistar receiving only sorbitol, used as vehicle of administration of the carvacrol (Wistar-Vehicle), one control group SHR, also receive only sorbitol (SHR-Vehicle), a third, treated with losartan (SHR-Losartan/50 mg/kg), and the fourth, treated with carvacrol (SHR - Carvacrol/20 mg/kg). Sorbitol, losartan and carvacrol were administered by oral gavage daily for 30-day.

Cardiac Autonomic Modulation is a Key Factor for High Blood Pressure in Adolescentes.

Background: The interest regarding hypertension among children and adolescents has increased since the blood pressure rating system was updated to be compared with the adult rating system, changing the terminology from "normal high" to "prehypertension".

Objective: This study aimed to analyze the association between cardiac autonomic modulation and pressure levels of adolescents.

Methods: 203 adolescents were grouped according to systolic blood pressure (SBP) and diastolic blood pressure (DBP).

Cardiac autonomic modulation of adolescents with different levels of sleep quality.

Unlabelled: Evaluate the cardiac autonomic modulation of adolescents with different levels of sleep quality.

Methods: Adolescents aged 11 to 17 years who presented themselves an explanation of the project with consent form signed by participated in the study. Anthropometric and hemodynamic data collected, and questionnaires.

Obesity as an additional factor for autonomic imbalance and poor sleep behavior in chronic obstructive pulmonary disease: a case-control study.

Objectives: We compared the autonomic modulation and sleep behavior of eutrophic and overweight patients with chronic obstructive pulmonary disease (COPD).

Methods: COPD participants were divided into the overweight and eutrophic groups. Pulmonary function, blood pressure, body composition, autonomic modulation, and the Pittsburgh Sleep Quality Index score were assessed.

Dose-related Effects of Resveratrol in Different Models of Pulmonary Arterial Hypertension: A Systematic Review.

Background: Pulmonary Arterial Hypertension (PAH) is a severe and progressive disease of pulmonary arterioles. This pathology is characterized by elevation of the pulmonary vascular resistance and pulmonary arterial pressure, leading to right heart failure and death. Studies have demonstrated that resveratrol possesses a protective effect on the mechanisms related to the genesis of the PAH-induced by different models.

Inspiratory muscle training improves autonomic modulation and exercise tolerance in chronic obstructive pulmonary disease subjects: A randomized-controlled trial.

Objectives: We aimed to evaluate the effect a regular inspiratory muscle training program on autonomic modulation measured by heart rate variability, exercise capacity and respiratory function in chronic obstructive pulmonary disease subjects (COPD).

Design: Single-center controlled study, with balanced randomization (1:1 for two arms).

Setting: A COPD reference hospital localized in Sao Luís, Brazil.

A Case-control Study of Exercise and Kidney Disease: Hemodialysis and Transplantation.

We aimed to analyze the effect of an exercise training program in autonomic modulation, and exercise tolerance of hemodialysis and kidney-transplanted patients. 4 groups of exercised and non-exercised patients undergoing hemodialysis and kidney-transplanted subjects had their biochemical tests, and heart rate variability evaluations analyzed. Also, sleep quality, anxiety and depression questionnaires were evaluated.

Short-term combined exercise training improves cardiorespiratory fitness and autonomic modulation in cancer patients receiving adjuvant therapy.

The present study aimed to investigate the impact of a short-term exercise training (ET) on the cardiorespiratory fitness and autonomic modulation of women with breast cancer who were receiving adjuvant radiotherapy, chemotherapy or hormonotherapy. Eighteen women previously diagnosed with breast cancer receiving adjuvant radiotherapy, chemotherapy or hormone therapy were randomly allocated into breast cancer nonexercise (BC) and exercise groups (BC+Ex). Moreover, nine healthy physically inactive volunteers were recruited to compose the noncancer control group (CG).

Effect of exercise training in heart rate variability, anxiety, depression, and sleep quality in kidney recipients: A preliminary study.

The aim of this study was to compare the sleep quality, depression, anxiety, and autonomic function of a group of kidney-transplanted recipients who joined a combined exercise program (KTR) or remained sedentary (KTR). A total of 20 kidney-transplanted recipients, split into two groups (10 KTR and 10 KTR), joined the study. Heart rate variability, cardiorespiratory capacity, depression, and sleep questionnaires were evaluated.

Cardiovascular Response of an Acute Exergame Session in Prepubertal Obese Children.

Purpose: We aimed to analyze the acute autonomic response of obese and eutrophic prepubertal boys to an exergame (EXG) session.

Materials And Method: Nine eutrophic (8.89 ± 2.

Effect of exercise training and detraining in autonomic modulation and cardiorespiratory fitness in breast cancer survivors.

Background: Breast cancer is one of the leading causes of death worldwide. Heart rate variability (HRV) has attracted scientific community attention in different pathologies, becoming thus an ultimate importance tool in both clinical and research setting, being a good predictor of cardiac events and mortality risk and also used in physical exercise and sports in general. The aim of the present study was to evaluate 12 weeks of exercise training and six weeks of detraining in cardiorespiratory capacity, and autonomic modulation in breast cancer patients.

Investigating the influence of morphology in the dynamical behavior of semicrystalline Triton X-100: insights in the detection/nondetection of the α'-process.

The paper investigates the influence of the crystalline structure in the dynamical behavior of semicrystalline Triton X-100 allowing enlightening the reason for the detection/nondetection of the α'-process. The work was preceded by the study of the full amorphous material for which dielectric relaxation spectroscopy (DRS) identified multiple relaxations: the α-process associated with the dynamical glass transition and two secondary relaxations (β- and γ- processes). To evaluate how crystallinity affects the detected relaxation processes, different crystallizations were induced under high and low undercooling conditions.
