Occupational and psychosocial stress among commercial aviation pilots.

The sources of occupational and domestic stress, together with life events and coping strategies, were assessed in terms of their influence on job dissatisfaction, mental health, and performance among a group of 442 commercial airline pilots. It was found that self-perceived poor performance was associated with job-related factors such as fatigue and anxiety about required courses, performance checks, and insufficient flying time, particularly among older pilots. Job dissatisfaction was predicted by lack of career opportunities, poor organizational climate and morale, and lack of autonomy at work, together with some domestic stressors (e.g., family health). Overall mental ill-health was found to be associated with lack of autonomy at work, fatigue, and flying patterns, together with an inability to relax and a lack of social support.

The sources of stress on the wives of commercial airline pilots.

The purpose of this study was to assess the impact of the pilot's job on the personal and life satisfaction of his wife. A representative sample of 282 wives of commercial airline pilots was investigated to empirically determine which sources of stress and demographic characteristics would predict life dissatisfaction. It was found, using multiple regression analysis, that life dissatisfaction was significantly predicted by "domestic role overload," and "the job's impact on social life," particularly for wives whose husbands worked for smaller airlines. In addition, the wives were concerned about the "fear of husband's job loss."

Properties of a phosphoprotein phosphatase from rat epididymal fat pads: deactivation of hormone-sensitive triglyceride lipase and activation of glycogen synthase in adipose tissue.

A phosphoprotein phosphatase has been partially purified from rat epididymal fat pads by a procedure utilizing ammonium sulfate and ethanol precipitations and chromatography on DEAE-Sephadex A-50. The phosphatase was eluted from Sephadex G-75 columns with an apparent molecular weight of 28 000. The phosphoprotein phosphatase catalyzed the reversible deactivation of protein kinase activated chicken adipose tissue hormone-sensitive triglyceride lipase. Phosphatase activity measured with activated triglyceride lipase as substrate was completely dependent upon the presence of metal ions (Mg2+, Ca2+, or Mn2+) and was inhibited by inorganic phosphate and adenine nucleotides. The fat pad phosphatase increased the rate of activation of glycogen synthase in rat adipose tissue infranatant fractions from fed and 24-h fasted rats but had little or no effect on synthase activity in infranatant fractions from rats fasted for 48 h. Fasting had no effect on rat fat pad phosphatase activity measured with triglyceride lipase as substrate, but phosphatase activity was decreased in preparations from diabetic rats.

Reference values for a multiple repetition 6-minute walk test in healthy adults older than 20 years.

PURPOSE: To (1) identify greatest 6-minute walk distance (6MWD) from among several repetitions (best 6MWD) in a wide age range of healthy volunteers to develop reference values for the multiple repetition 6MWD, and (2) investigate the influence of demographics, anthropometrics, and habitual exercise activity on best 6MWD. METHODS: Four 6MWD were performed on the same day in a 20-meter corridor by 41 male and 38 female healthy volunteers ranging in age from 20 to 80 years. The greatest 6MWD by each subject from among four 6MWDs was the primary outcome measure. RESULTS: Eighty-six percent had their best 6MWD after the first walk; an average increase of 43 meters was observed from first to best 6MWD (P < 0.003). Best 6MWD averaged 698 +/- 96 meters and was inversely related to age (P < 0.001), directly to height (P < 0.001), and was greater in men than women (P < 0.0002). A regression model accounted for 41% of between-subject variability in best 6MWD (P < 0.00000001). In a subset of older subjects, predicted 6MWD significantly underestimated measured best 6MWD when reference values were used from another study where test familiarization was not provided, but this difference disappeared when value were used from the present and a third study where test familiarization was provided. CONCLUSIONS: The present study is the first to provide predicted 6MWD values performed with multiple repetitions and for subjects in the 20-40-year-old age range. Selection of appropriate predicted 6MWD values for interpretation of performance should be guided by subject age and degree of test familiarization provided.

Resolving the control struggle on an eating disorders unit.

The authors describe the process by which the nursing staff of an eating disorder program was able to identify an ineffective treatment model and to implement some needed changes. They describe the Therapeutic/Administrative Split Model, a method to improve communication and treatment planning between the nurse and psychiatrist. How family control issues are mirrored in the treatment process, and played out within the transference, are also explored.
