[Characteristics of human sleep, diurnal periodicity of physiological functions and work capacity indices on the 1st day after a changeover from the usual to split alternation of sleep and wakefulness].

The effects of sectionated and shifted workrest cycles on diurnal variations of physiological functions, mental performance and sleep parameters have been studied. It has been demonstrated that the first day on sectionated work-rest cycles brings about the least changes. It has been concluded that the sectionated work-rest cycles can be recommended for transitional-based schedules of scientists working in an unusual environment.

[Effect of the nutritional regimen on work capacity level of students].

The influence was studied on 2-and 3-fold nutritional pattern on the performance capacity of 43 students, who continuing their ordinary work under routine conditions were receiving isocaloric rations identical in their qualatitative composition. The regularity of nutrition was found to have a favourable effect; it heightened the accuracy of work according to correction tables; increased the speed of the visual-motor reaction during working hours; reduced the number of erroneous reactions to a differentiated stimulator the positive influence of a 3-fold nutritional regimen being more pronounced.

Cardiovascular impairment and physical working capacity in children with chronic renal failure.

Forty children with chronic renal failure (CRF) on conservative treatment, on hemodialysis, or after renal transplantation and 22 children respresenting a non-uremic control group were subjected to repeated cardiologic examinations by ECG, PCG, chest X-rays and cycle ergometer exercise tests to monitor signs of uremic heart disease and to evaluate physical working capacity (W170). In the CRF group a progressive impairment of W170 was found, starting at an early stage of the disease. Exercise tolerance was inversely related to the degree of CRF. A correlation was also found between W170 and renal anemia. After starting dialysis, W170 failed to increase significantly. Immediately after dialysis an acute drop in W170 occurred. Renal anemia was found to be the main pathogenetic factor of uremic heart disease in children. In some cases hypercirculation following arteriovenous fistulae became equally important as a cause of reduced myocardial performance. Physical rehabilitation, as measured by exercise tolerance tests, was better in transplanted than in dialysed children.

Iron deficiency and reduced work capacity: a critical review of the research to determine a causal relationship.

The causal relationship between iron deficiency and physical work capacity is evaluated through a systematic review of the research literature, including animal and human studies. Iron deficiency was examined along a continuum from severe iron-deficiency anemia (SIDA) to moderate iron-deficiency anemia (MIDA) to iron deficiency without anemia (IDNA). Work capacity was assessed by aerobic capacity, endurance, energetic efficiency, voluntary activity and work productivity. The 29 research reports examined demonstrated a strong causal effect of SIDA and MIDA on aerobic capacity in animals and humans. The presumed mechanism for this effect is the reduced oxygen transport associated with anemia; tissue iron deficiency may also play a role through reduced cellular oxidative capacity. Endurance capacity was also compromised in SIDA and MIDA, but the strong mediating effects of poor cellular oxidative capacity observed in animals have not been demonstrated in humans. Energetic efficiency was affected at all levels of iron deficiency in humans, in the laboratory and the field. The reduced work productivity observed in field studies is likely due to anemia and reduced oxygen transport. The social and economic consequences of iron-deficiency anemia (IDA) and IDNA have yet to be elucidated. The biological mechanisms for the effect of IDA on work capacity are sufficiently strong to justify interventions to improve iron status as a means of enhancing human capital. This may also extend to the segment of the population experiencing IDNA in whom the effects on work capacity may be more subtle, but the number of individuals thus affected may be considerably more than those experiencing IDA.

[Assessment of working capacity in a group of subjects affected with obstructive respiratory disease (author's transl)].

Ventilatory function was studied by the authors in 43 subjects affected with obstructive respiratory disease. The research was performed both at rest and during two exercise tests -- 60 and 100 watts, respectively. The subjects were divided into three groups on the basis of tidal volume (at 30 1 ventilation) / vital capacity ratio. It was found that during muscular effort subjects with major impairment of spirometric indexes hypoventilated, whereas the opposite occurred in patients with lesser impairment. Moreover, subjects hyperventilating during muscular work were found to have brandypnea, whereas the opposite occurred in hyperventilating patients. It is suggested that progressing and worsening of obstructive emphysema lead to a relative hypoventilation during muscular work, which is due to an "inability" to increase the frequency of breathing.

[Assessment of the working capacity in functional rehabilitation (author's transl)].

One of the most important factors in rehabilitation is the assessment of the handicapped's capacity to return to this previous work, or possibly to choose a new job (vocational rehabilitation) or to adapt the operation station. It is thus advisable to elaborate an assessment system of the working possibilities in order to better program individually the activities of functional rehabilitation, or retraining to effort, or of retraining to work. The assessment of the working capacity must take account of 3 principles: to observe--to assess--to guide, and this throughout rehabilitation, considering it must be precocious, progressive and continuous. The objective is to allow the handicapped person to determine his project of social and vocational rehabilitation. Therefore the program will be established according to pathology, characteristics of the profession and principles of the work. The statement will be basically turned to the questionnaire analysing the vocational activity requirements (the contents, the why and its grounds) and so to consider the vocational activity with regard to the functional shortage either temporary or permanent.

[Guidelines for the sociomedical assessment of performance in patients suffering from inflammatory bowel disease].

The following guidelines were developed for the medical assessment services of the German Federal Insurance Institute for Salaried Employees (BfA). Starting from day-to-day practice, criteria and attributes to guide decisions for a systemization of the sociomedical assessment of performance in inflammatory bowel disease (Crohn's disease, ulcerative colitis) were compiled. The guidelines aim at standardising the sociomedical assessment of performance and help to make the decision-making process more transparent -- e. g. for the assessment of applications for decreased earning capacity benefits. The guidelines summarise typical manifestations of inflammatory bowel disease and describe the necessary medical information for the sociomedical assessment of performance. Relevant assessment criteria for the medical history, clinical examination, and for diagnostic tests are illustrated. The assessment of the individual's capacity is outlined, taking occupational factors into account. Following the determination of dysfunctions the remaining abilities and disabilities, respectively, are deduced and compared with occupational demands. Finally, inferences are drawn regarding the occupational capacity of the individual.

[Management of non-specific musculoskeletal disorders--role of ergonomics].

Non-specific musculoskeletal disorders are a major health problem. Despite good prognosis socio-economic burden is important. Just a few treatment strategies are known to reduce work-disability. An early ergonomic assessment helps to determine the level of disability and further rehabilitation strategies. An assessment consists of a self-rating of the physical capacities and a physical performance test. Work-place demands and psychosocial factors should also be considered by interview. An ergonomic work-place analysis supports this information and facilitates reintegration. Furthermore, work-place adaptations can be performed.

The safety of static-dynamic effort soon after myocardial infarction.

Many activities of daily living require static-dynamic effort. To evaluate the safety of such effort 3 weeks after myocardial infarction, 27 male patients underwent a weight-carrying test requiring 5 minutes of treadmill ambulation with graded weight loads of 10 to 30 pounds. The hemodynamic responses with weight carrying were compared to that of a predischarge graded dynamic exercise test. The peak heart rate was significantly lower (p less than 0.01) with weight carrying, the peak systolic blood pressure did not differ, and the diastolic pressure was significantly higher (P less than 0.01). ST segment depression and angina pectoris occurred less frequently with weight carrying. The type and frequency of ventricular arrhythmias were similar between the two tests. We conclude that many men are capable of performing static-dynamic activity equivalent to carrying up to 30 pounds by 3 weeks after myocardial infarction.

[Post-traumatic stress after occupational accidents].

This study focuses on post-traumatic stress disorder in a follow up one to two years after the occupational accident. The aim was to estimate the prevalence of PTSD, changes in general health status and issues of compensation. The material was all serious accidents registered in the Danish National Register of Work Accidents during 1991. Seriousness was defined by type of injury, including all cases of amputations, bone fractures and extensive body lesions. Of 4745 possible, 3663 persons (77%) participated in a questionnaire study. The prevalence fulfilling the complete set of criteria of posttraumatic stress disorder as a chronic state was 2.8% (102 persons), of whom half had been given compensation. Among the most severe accidents the prevalence was 7.6%. In conclusion, in a large cohort of persons with moderate and severe occupational injuries this study demonstrated that post-traumatic stress disorder and lasting psychological distress should be a matter for concern in addition to the physical injury.
