BACKGROUND: Logistic regression is often used for mediation analysis with a dichotomous outcome. However, previous studies showed that the indirect effect and proportion mediated are often affected by a change of scales in logistic regression models. To circumvent this, standardization has been proposed. The aim of this study was to show the...

Fuel efficiency optimization and emission reduction have become essential parts of engine research, due to the growing demand for environmental protection. In this paper, a computationally efficient optimization method has been applied to maximize the fuel efficiency under constraints of maximum pressure rise rate and various pollutant emissions...

Objectives: Age-related changes in articular cartilage are likely to play a role in the aetiology of osteoarthritis (OA). One of the major age-related changes in cartilage is the accumulation of advanced-glycation-endproducts (AGEs). Since, cartilage tissue is not readily available from patients for studying AGE levels, alternative approaches...

Information on prognostic factors for duration of sick leave due to low-back pain (LBP) is growing. In this prospective cohort study, prognostic factors for duration of sick leave and course of disability were identified at a very early stage of sick leave due to LBP. A total of 615 workers calling in sick from work due to LBP at an occupational...

Objective: To investigate the relationship between work and quality of life (QOL) in patients with rheumatoid arthritis (RA) and ankylosing spondylitis (AS) aged 16-59. Methods: 1056 patients with RA and 658 with AS were included in the study. Data were obtained by postal questionnaire, which included severa generic and disease related QOL...

Background: Nutritional factors exert promising actions on the skin, but only scant information is available on the modulating effects of physiologic concentrations of nutrients on the skin condition of humans. Objective: The objective was to evaluate whether nutrient concentrations in serum and diet are associated with the skin condition of...

Subclinical vitamin B-12 deficiency is common in the elderly. Encouraged by early indications, we investigated the plasma vitamin B-12 status in association with bone mineral content (BMC) and bone mineral density (BMD) in frail elderly people. Data of 194 free-living Dutch frail elderly (143 women and 51 men) were available. BMC and BMD were...

Objectives. To investigate whether the single-item fatigue question of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and the Multidimensional Fatigue Inventory (MFI) are appropriate instruments to measure fatigue in ankylosing spondylitis (AS); to identify factors that influence fatigue in AS; and to assess how fatigue in all...

Objectives: To assess the labour market position of patients with ankylosing spondylitis (AS) in relation to disease duration and to identify potential factors in relation to withdrawal from the labour force. Methods: A cross sectional mail survey was conducted among 658 patients with AS. Participation in the labour force was defined as having a...

The relationship of preterm birth to health-related quality of life (HRQoL) was examined for children aged 1 to 4 years. Three gestational age groups with a NICU history were selected, <32 weeks (n=65), 32 to 36 weeks (n=41),≥37 weeks (n=54), and a reference group from the open population (n=50). The main instrument was the TNO-AZL Preschool...

A pilot study was conducted regarding the effects of working posture, handling frequency, and task duration on musculoskeletal discomfort. Participants rated their discomfort perceived while perform-ing a repetitive task at 8 different combinations of manipulations. Pauses between the work periods lasted 15 min. Discomfort was rated according to...

Cross-section comparisons of the effect of age on physiological responses to heat stress have yielded conflicting results, in part because of the inability to separate chronological age from factors which change in concert with the biological aging process. The present study was designed to examine the relative influence of age on cardiovascular...
