Characteristics of polymedicated (≥ 4) elderly: a survey in a community-dwelling population aged 60 years and over.

BACKGROUND: Polypharmacy is an important concern for patient safety and has been associated with increased adverse drug reactions, hospitalization and mortality in the elderly. OBJECTIVE: In light of the above, the present study aimed to assess the major characteristics associated with polypharmacy (≥ 4 drugs) in a larger population of apparently healthy older subjects over 60 years. STUDY-DESIGN: Cross-sectional study. SETTING: The preventive medical center (CMP) in Nancy. PARTICIPANTS: 2,545 volunteers (1,175 women, 1,370 men) aged 60 years and older (66 ± 4.8 years) were included from the Senior health examination study. MEASUREMENTS: All subjects underwent clinical, biological examinations. Sociodemographic data, practice of regular physical activity and drug intake data were collected. A self-administered questionnaire of health status, psychological status and questions regarding falls were collected. RESULTS: The prevalence of polypharmacy in this study was 29.9%. The number of drugs in polymedicated people was 5.67 ± 1.82 versus 1.32 ± 1.11 in non polymedicated people; p≤0.01. Multivariate analyses identified 6 independent variables associated with polypharmacy: age over 65 years (OR = 1.58 95% CI: [1.05 - 2.38]; p = 0.03), poor self-perceived health status (2.79 [1.80 - 4.31]; p ≤ 0,01), history of falls (1.66 [1.02 - 2.71]; p = 0.04), lack of a physical activity (1.50 [1.001 - 2.26]; p = 0.049), metabolic syndrome (3.17 [1.95 - 5.15]; p ≤ 0,01), low or medium education level (2.20 [1.24 - 4.30]; p = 0.02). CONCLUSION: Among community-dwelling people aged 60 years and over, in addition to the presence of several diseases and advanced age, the psychological and socio-educative factors may influence drug intake and polypharmacy in the elderly. Physicians should be take into account these considerations before issuing any prescriptions and review all medications used at every visit to avoid unnecessary addictions or dangerous drug-drug interactions.

Study of Mini-Mental State Exam evolution in community-dwelling subjects aged over 60 years without dementia.

OBJECTIVE: In recent years, the Mini-Mental State Examination (MMSE) has been widely used and has been proposed for cognitive decline screening in the framework of a systematic geriatric evaluation in health centers. The aim of the present longitudinal study was to identify the potential determinants of MMSE score and its evolution over a 4-year period in a population aged over sixty years with good general health without dementia and consulting for a health check-up. DESIGN: Longitudinal study. SETTING: The preventive medical center (CMP) in Nancy. PARTICIPANTS: 687 subjects over 60 years of age (mean age 65.6 ± 5.07 years) were included from the Senior health examination study. MEASUREMENTS: All subjects underwent 2 visits over a period of 4 years. MMSE measurement and a self-administered questionnaire of emotional and psychological state were evaluated at baseline and at the follow-up visit. RESULTS: The major components of total variance of baseline MMSE were represented by education level, practice of regular physical activity, nervousness and despair. Multivariate analysis identified 3 variables at baseline visit that independently predicted annual changes in MMSE: MMSE score, education level and "Difficulty in social relations" (r= -0.222, 0.154 and -0.255 respectively). CONCLUSIONS: Education level and several psychological factors may influence MMSE score and its evolution over time in community-dwelling subjects aged over 60 years without dementia. In these subjects, a low MMSE score does not predict cognitive decline over a period of 4 years. Therefore, the reliability of MMSE in this type of population is questionable.

The HITRAN database: 1986 edition.

A description and summary of the latest edition of the AFGL HITRAN molecular absorption parameters database are presented. This new database combines the information for the seven principal atmospheric absorbers and twenty-one additional molecular species previously contained on the AFGL atmospheric absorption line parameter compilation and on the trace gas compilation. In addition to updating the parameters on earlier editions of the compilation, new parameters have been added to this edition such as the self-broadened halfwidth, the temperature dependence of the air-broadened halfwidth, and the transition probability. The database contains 348043 entries between 0 and 17,900 cm(-1). A FORTRAN program is now furnished to allow rapid access to the molecular transitions and for the creation of customized output. A separate file of molecular cross sections of eleven heavy molecular species, applicable for qualitative simulation of transmission and emission in the atmosphere, has also been provided.
