Detection mechanisms for processing delays in simulated vented hearing devices.

Processing delays are a disturbing factor in hearing devices, especially with vented or open fits. While the disturbance due to delays is well characterized, neither have the perception thresholds of delays been systematically assessed, nor are the perceptual detection mechanisms clear. This study presents experiments determining the delay detection thresholds in simulated linear vented hearing devices in normal-hearing listeners, where spectral effects of delays were either compensated or not.

Effectiveness of a voluntary nutrition education workshop in a state prison.

Improved nutrition has implications for both prisoners and the penal system. This study evaluated a pilot intervention to improve nutrition in prisoners. Residents of a correctional substance abuse program (SAP) completed a health risk appraisal (HRA) upon entering the SAP and at completion.

The costs of short sleep.

Sleep plays an important role in workers' lives, allowing them to relax, restore, and revitalize their bodies, minds, and emotions every 24 hours. Sleep repairs the physical body to improve and maintain general health, consolidate learning and memory, and recharge the psychological batteries to maintain emotional balance and well-being. Quality sleep is as important as nutrition or exercise in maintaining overall health.

[Paraneoplastic IgA nephritis as the initial symptom of bronchial carcinoma].

We report on a 45-year old patient who was treated for IgA-Nephritis for 9 months. During treatment he developed coughing and dyspnoea which led to diagnose a central stenosing NSCLC at the tracheobronchial angle. Cancer treatment by x-ray showed a good response, e.
