Pulmonary hypertension is a potentially fatal disease. Despite pharmacological advances in pulmonary hypertension, fatigue remains common in patients with pulmonary hypertension. A convenience sample of 120 participants at an international patient conference completed the Multidimensional Fatigue Inventory (MFI)-20 scale. Data on New York Heart Association Functional Class, body mass index, oxy...

BACKGROUND Multiple sclerosis (MS) is a neurological disease with fatigue as most prevalent symptom. Psychopathological symptoms, physical and mental dysfunctions and body mass abnormalities potentially could deteriorate fatigue. Thus, in this study, we aimed at evaluating the effect of these factors on fatigue severity of MS patients. METHODS In this cross-sectional study, 162 patients with ...

Drowsiness and fatigue are serious problems in all transportation systems. One persistent issue is the lack of an agreed definition of these respective energetic states. Here we review the theoretical approaches (cognitive versus physiological) framing the driver fatigue problem. Known contributing factors to drowsiness include sleep debt, circadian rhythm, and shift work. However, we also sugg...

OBJECTIVES To determine, using longitudinal analyses, if retirement is followed by a change in the risk of incident chronic diseases, depressive symptoms, and fatigue. Design Prospective study with repeat measures from 7 years before to 7 years after retirement. SETTING Large French occupational cohort (the GAZEL study), 1989-2007. Participants 11 246 men and 2858 women. MAIN OUTCOME MEASUR...

PURPOSE/OBJECTIVES To examine the relationships among fatigue and physical and mental quality of life (QOL) and different adjuvant chemotherapy regimens in patients with stage I-IIIA breast cancer prior to, during, and after treatment. DESIGN Longitudinal, descriptive design embedded in a randomized, clinical trial. SETTING Outpatient oncology clinics in the midwestern United States. SAMP...

Although there are several studies on the effects of mental fatigue on task performance, still much is unknown about the cognitive processes that underlie performance deficits under fatigue. In the current study we test the idea that behavioral manifestations of mental fatigue may be linked to compromised executive control. Executive control refers to the ability to regulate perceptual and moto...

Driver distraction is caused by a competing activity and leads to unsafe driving. Mental workload changes with task demands and influences performance. Though distraction and mental workload are strongly related, they are not the same. Performance motivation and task engagement influence performance and consequently distraction but not workload; environment complexity and driver state influence...

It is known that Fe deficiency has a negative impact on cognitive function in children by altering brain energy metabolism and neurotransmitter function. It is unclear whether Fe deficiency has detrimental effects on cognition, mental health and fatigue in women of childbearing age. Our aim was to systematically review the literature to determine whether Fe deficiency in women of childbearing a...

INTRODUCTION Mental exertion is a psychophysiological state caused by sustained and prolonged cognitive activity. The understanding of the possible effects of acute mental exertion on physical performance, and their physiological and psychological responses are of great importance for the performance of different occupations, such as military, construction workers, athletes (professional or rec...

This paper describes an in-vehicle non-intrusive biopotential measurement system for driver health monitoring and fatigue detection. Previous research has found that the physiological signals including eye features, Electrocardiography (ECG), and their secondary parameters such as HR and HRV are good indicators of health state as well as driver fatigue. A conventional bio-potential measurement ...
