OBJECTIVES To determine the mediating effects of depression on health-related quality of life and fatigue in individuals with multiple sclerosis (MS). DESIGN A cross-sectional study. SETTING Tertiary urban hospital. PARTICIPANTS One hundred and eight patients (54% women) with MS participated in this study. OUTCOME MEASURES Demographic and clinical data (weight, height, medication and ne...

OBJECTIVE Fatigue is frequently reported in sarcoidosis and appears to differ between patients. Three types of fatigue (Early Morning Fatigue, Intermittent Fatigue, and Afternoon Fatigue) are described in the literature for sarcoidosis, but have not been validated. Therefore, the aim of this study was to examine whether these types of fatigue can be identified in sarcoidosis. METHODS Outpatie...

Patients with head and neck cancer (HNC) receiving intensity-modulated radiation therapy (IMRT) have particularly high rates of fatigue, and pre- and post-radiotherapy fatigue are prognostic factors for pathologic tumor responses and poor survival. Although inflammation has been proposed as one of the potential mechanisms of fatigue in cancer patients, findings have not been consistent, and the...

GOALS To assess whether endoscopist fatigue adversely affects the adenoma detection rate (ADR) during screening colonoscopy. BACKGROUND Endoscopist fatigue may affect the ADR during colonoscopy; however, this association has not been directly studied. STUDY A prospective, multi-center study was performed on screening colonoscopies performed for asymptomatic subjects between March 2012 and D...

Fatigue life estimation is one of the most important design considerations in mechanical parts which are subjected to alternating loads. When loads act along several axes, multiaxial fatigue approach should be used to obtain more accurate results than uniaxial fatigue method. In this paper stress analysis of the steel shaft of a high speed microgenerator rotor with 47750 rpm and 100kW is carrie...

Background: Fatigue is commonly reported by cancer patients. In some instances it can persist after treatment is completed. In order to develop effective treatment strategies it is important to understand the mechanisms underlying the development of fatigue and to be able to predict those that may be at greatest risk of experiencing fatigue during and following treatment. The current paper exam...

Ultrasonic testing for fatigue crack detection in metallic members are commonly performed using time domain analysis of Rayleigh waves. This approach will be successful only if the fatigue cracks produce strong interaction with the Rayleigh waves. The optimum frequency range of ultrasonic Rayleigh waves for scanning long structural members in the field is from 0.5 to 2.25 MHz because higher fre...

NASA has conducted an Airframe Structural Integrity Program to develop the methodology to predict the onset of widespread fatigue damage in lap-splice joints of fuselage structures. Several stress analysis codes have been developed or enhanced to analyze the lap-splice-joint configuration. Fatigue lives in lap-splicejoint specimens and fatigue-crack growth in a structural fatigue test article a...

AIMS This paper is a qualitative investigation that aims to investigate the lived experience of fatigue in patients with motor neurone disease-a progressive and fatal neurological condition. BACKGROUND Fatigue is a disabling symptom in motor neurone disease (MND) that affects a large number of patients. However, the term "fatigue" is in itself imprecise, as it remains a phenomenon without a w...
