Aging, diabetes, and hypertension are associated with decreased nasal mucociliary clearance.

BACKGROUND: We showed previously that nasal mucociliary clearance was decreased in critically ill elderly subjects, most of whom had diabetes mellitus (DM) and/or hypertension (HTN). To determine if these changes were due to the effects of aging, disease, or critical illness, we studied nasal mucociliary clearance and mucus properties in an ambulatory population consisting of young, elderly, and healthy subjects and those with DM, HTN, or both. METHODS: Of 440 subjects contacted, 252 entered the study. The subjects were divided into the following groups: (1) healthy (n 5 79, 18-94 years, 50 men) and (2) DM and/or HTN, of which 37 had DM (14-90 years, 12 men), 52 had HTN (23-90 years, 12 men), and 84 had both DM and HTN (25-82 years, 33 men). Subjects were also grouped by age: , 40 years, 40 to 59 years, and 60 years. We assessed demographic and clinical data, quality of life using the 36-Item Short Form Health Survey (SF-36) questionnaire, nasal mucociliary clearance using the saccharine transit test (STT), and in vitro mucus properties by examining the sneeze (high airflow) clearability and contact angle. A logistic regression analysis for prolonged STT . 12 min was used, and we controlled for age, sex, and diseases. RESULTS: Subjects aged . 60 years reported a decreased SF-36 physical component relative to other age groups. Sex, BMI, BP, heart rate, pulse oximetry, blood glucose level, and mucus properties were not associated with prolonged STT. Aging and DM and/or HTN independently increased the risk of prolonged STT. CONCLUSIONS: Aging and DM, HTN, or both diseases are independently associated with decreased nasal mucociliary clearance. This may predispose toward respiratory infections.

Respiratory rehabilitation: a physiotherapy approach to the control of asthma symptoms and anxiety.

OBJECTIVES: The objectives of this study were to verify the degree of anxiety, respiratory distress, and health-related quality of life in a group of asthmatic patients who have experienced previous panic attacks. Additionally, we evaluated if a respiratory physiotherapy program (breathing retraining) improved both asthma and panic disorder symptoms, resulting in an improvement in the health-related quality of life of asthmatics. METHODS: Asthmatic individuals were assigned to a chest physiotherapy group that included a breathing retraining program held once a week for three months or a paired control group that included a Subtle Touch program. All patients were assessed using the Diagnostic and Statistical Manual of Mental Disorders IV, the Sheehan Anxiety Scale, the Quality of Life Questionnaire, and spirometry parameter measurements. RESULTS: Both groups had high marks for panic disorder and agoraphobia, which limited their quality of life. The Breathing Retraining Group program improved the clinical control of asthma, reduced panic symptoms and agoraphobia, decreased patient scores on the Sheehan Anxiety Scale, and improved their quality of life. Spirometry parameters were unchanged. CONCLUSION: Breathing retraining improves the clinical control of asthma and anxiety symptoms and the health-related quality of life in asthmatic patients.
