Populations are becoming progressively older thus presenting symptoms of diminished organ function due to degenerative processes. These may be physiological or caused by additional factors damaging the organ. Presbyacusis refers to the physiological age-related changes of the peripheral and central auditory system leading to hearing impairment and difficulty understanding spoken language.

Recruiting adolescents into smoking cessation programs has been challenging, and there is a lack of effective smoking cessation interventions for this age group. We aimed to assess whether the approach of using aging images can be used to recruit young, female smokers for a smoking cessation course. In this study, 853 14- to 18-year-old subjects were photographed (2006-2007).

Problem: There is a scarcity of data simultaneously evaluating the relationship of health behavior, health perception, work characteristics, and demographic variables with sickness absenteeism in industrial employees.

Method: Predictors and possible confounders (smoking, physical activity, alcohol intake, age, gender, body mass index, income) were regressed against frequency indices and the time lost index derived from the day-to-day absence data of 1524 employees at a manufacturing plant in Germany. Frequency indices were the number of sick-leave spells of 1, 2-3, 4-5, and >5 days within 1 year.

This study investigated the contribution of psychosocial work characteristics (decision latitude, job demand, social support at work, and effort-reward imbalance) to health-related quality of life. Data were derived from 2 aircraft manufacturing plants (N=1,855) at the start of a longitudinal study. Regression analysis showed that work characteristics (1st model) explained 19% of the variance in the mental summary score of the Short Form-12 Health Survey.

Exaggerated procoagulant responses to acute mental stress may contribute to coronary thrombosis, and continuing low-grade systemic coagulation activation may link negative affect with the development of coronary artery disease. We investigated whether negative and positive affect and perceived social support would moderate stress procoagulant reactivity. Psychological functioning, exhaustion, negative affectivity, depression, anxiety, worrying, vigor, and social support were assessed in 27 apparently healthy men (mean age 47 +/- 8 years) who underwent the 13-min Trier Social Stress Test combining preparation, speech, and mental arithmetic.

Acute mental stress induces a significant increase in plasma interleukin (IL)-6 levels as a possible mechanism for how psychological stress might contribute to atherosclerosis. We investigated whether the IL-6 response would habituate in response to a repetitively applied mental stressor and whether cortisol reactivity would show a relationship with IL-6 reactivity. Study participants were 21 reasonably healthy men (mean age 46+/-7 years) who underwent the Trier Social Stress Test (combination of a 3-min preparation, 5-min speech, and 5-min mental arithmetic) three times with an interval of 1 week.

Acute mental stress may contribute to atherosclerosis by affecting inflammation and coagulation; however, the crosstalk between inflammation and coagulation during stress has not been studied. In the present study, we investigated the association of plasma fibrinogen, plasma IL-6 (interleukin-6) and free salivary cortisol with the procoagulant marker D-dimer reflecting fibrin formation both over a 2-h period and in response to acute mental stress. Twenty-one male volunteers (mean age, 47+/-8 years) underwent the Trier Social Stress Test combining a 3-min preparation phase, a 5-min job interview and 5-min mental arithmetic test before an audience.
