PURPOSE To compare sleep quality and sustained attention of patients with Upper Airway Resistance Syndrome (UARS), mild Obstructive Sleep Apnea (OSA) and normal individuals. METHODS UARS criteria were presence of excessive daytime sleepiness (Epworth Sleepiness Scale-ESS-≥ 10) and/or fatigue (Modified Fatigue Impact Scale-MFIS-≥ 38) associated to Apnea/hypopnea index (AHI) ≤ 5 and Respiratory...

PURPOSE Fatigue is a common adverse effect of cancer treatment and may persist for years after treatment completion. However, risk factors for post-treatment fatigue have not been determined. On the basis of studies suggesting an inflammatory basis for fatigue, this study tested the hypothesis that expression-regulating polymorphisms in proinflammatory cytokine genes would predict post-treatmen...

cordingly, slowing of the maximum relaxation rate (MRR) of inspiratory muscles during short and sharp sniffs is considered to be an index of inspiratory muscle fatigue [5] . Sniff MRR is commonly calculated from esophageal pressure traces; however, a non-invasive and reliable measure of inspiratory muscle MRR can be obtained by measuring sniff nasal pressure [6] . This non-invasive technique ha...

background & aim : increasing students’ academic stress especially during taking final exams may result in sleep  disorders, fatigue, poor academic performance and low functional efficiency. the aim of this study was to determine the relationship between sleep quality with fatigue severity and academic performance of nursing students. methods & materials : in a cross-sectional study, the sleep ...

OBJECTIVES Many patients with Parkinson's disease (PD) suffer from non-motor symptoms like sleep disturbances, excessive daytime sleepiness and fatigue. The aim of our research was to explore whether fatigue is related to sleepiness and sleep problems, depression and functional status, controlled for age, gender and disease duration. METHODS The sample consisted of 78 PD patients from Eastern...

CONTEXT The biology of fatigue and depression in cancer patients is poorly understood. Hypotheses regarding cytokines and growth factors related to sickness behavior and disruption of circadian signaling have been proposed. OBJECTIVES We prospectively examined proinflammatory cytokines (e.g., sickness behavior model) and epidermal growth factor receptor (EGFR) ligands (e.g., circadian disrupt...

BACKGROUND Fatigue, which interferes with one's physical and mental operation, resulting in strength reduction and weakness, is considered one of the most important issues in the workplace. In addition, it can cause diseases, occupational accidents, and a reduction in an individual's efficiency. The aforementioned effects can be aggravated by fatigue in shift workers who experience sleep distur...

Background and aims: Fatigue is associated with longitudinal ratings of health in patients with chronic obstructive pulmonary disease (COPD). Although the degree of airflow obstruction is often used to grade disease severity in patients with COPD, multidimensional grading systems have recently been developed. The aim of this study was to investigate the relationship between perceived and actual...
