The study monitored physiological parameter changes after 120-min of simulated driving. Blood pressures, heart rate (HR), heart rate variability (HRV) and palm temperatures were measured using an ANSWatch(®) monitor. Subjects were divided into two groups (A & B). Both groups performed 2-hour driving, but group B additionally took a 15-min exercise break. Heart rate, systolic pressure, LF/HF, an...

Measures of diaphragmatic electromyography (Edi), and respiratory mechanics, have demonstrated early changes before clinical complications. However, automatic Edi data collection is not adequate today due mainly to severe artefacts as well as to loss of signal. We thus intended to develop a new device with embedded artificial intelligence to optimize automatic Edi recordings independantly of ar...

Four different limit states formats for the fatigue design of reinforced concrete and prestressed concrete structures are described and compared within the context of simple second level reliability theory. All four formats lend themselves to reliability treatment but the cycle format appears to be the most useful at the present time, given the limited quantity of design data available on the f...

PURPOSE/OBJECTIVES To examine how attentional fatigue changed from the time of simulation to four months after the completion of radiation therapy and to investigate whether specific variables predicted initial levels and trajectories of attentional fatigue. DESIGN Descriptive, longitudinal study. SETTING Two radiation therapy departments. SAMPLE 73 women with breast cancer who received p...

Surface electromyographic (sEMG) activity of the biceps muscle was recorded from 13 subjects. Data was recorded while subjects performed dynamic contraction until fatigue and the signals were segmented into two parts (Non-Fatigue and Fatigue). An evolutionary algorithm was used to determine the elbow angles that best separate (using Davies-Bouldin Index, DBI) both Non-Fatigue and Fatigue segmen...

OBJECTIVE To systematically review fatigue instruments used in patients with systemic lupus erythematosus (SLE) and to seek consensus on which instruments should be recommended for future studies and which data on comorbid conditions should be reported when evaluating fatigue in patients with SLE. METHODS We used data from Medline and EMBase databases (from January 1970 to June 2006), clinica...

PURPOSE/OBJECTIVES To test whether sleep disturbance mediates the effect of pain on fatigue. DESIGN Cross-sectional. SETTING Radiation therapy clinic, oncology ambulatory clinic, and inpatient oncology unit in an urban teaching hospital. SAMPLE 84 patients with cancer with multiple primary diagnoses who were experiencing pain. Fifty-three percent were female and 92% were Caucasian, with a...

In view of the large body of research demonstrating that optimism has beneficial effects on people’s well-being and health, one may assume that it also protects against fatigue. However, few studies have investigated the association between optimism and cancer-related fatigue in cancer patients, and the results are inconsistent. Thus our aim was to investigate if optimism is associated with sev...

BACKGROUND Oral health and academic performance are important contributing factors for a student's professional life. Countless factors affect both, among which sleep, vitality and fatigue are less explored areas that also have a strong impact. OBJECTIVE The objective of the study was to assess the association of sleep disturbances, fatigue and vitality with self reported oral health status, ...
