Longitudinal Associations between Concurrent Changes in Phenotypic Frailty and Lower Urinary Tract Symptoms among Older Men.

BACKGROUND: Lower urinary tract symptoms (LUTS) are associated with prevalent frailty and functional impairment, but longitudinal associations remain unexplored. OBJECTIVES: To assess the association of change in phenotypic frailty with concurrent worsening LUTS severity among older men without clinically significant LUTS at baseline. DESIGN: Multicenter, prospective cohort study. SETTING: Population-based. PARTICIPANTS: Participants included community-dwelling men age ≥65 years at enrollment in the Osteoporotic Fractures in Men study. MEASUREMENTS: Data were collected at 4 visits over 7 years. Phenotypic frailty score (range: 0-5) was defined at each visit using adapted Fried criterion and men were categorized at baseline as robust (0), pre-frail (1-2), or frail (3-5). Within-person change in frailty was calculated at each visit as the absolute difference in number of criteria met compared to baseline. LUTS severity was defined using the American Urologic Association Symptom Index (AUASI; range: 0-35) and men with AUASI ≥8 at baseline were excluded. Linear mixed effects models were adjusted for demographics, health-behaviors, and comorbidities to quantify the association between within-person change in frailty and AUASI. RESULTS: Among 3235 men included in analysis, 48% were robust, 45% were pre-frail, and 7% were frail. Whereas baseline frailty status was not associated with change in LUTS severity, within-person increases in frailty were associated with greater LUTS severity (quadratic P<0.001). Among robust men at baseline, mean predicted AUASI during follow-up was 4.2 (95% CI 3.9, 4.5) among those meeting 0 frailty criteria, 4.6 (95% CI 4.3, 4.9) among those meeting 1 criterion increasing non-linearly to 11.2 (95% CI 9.8, 12.6) among those meeting 5 criteria. CONCLUSIONS: Greater phenotypic frailty was associated with non-linear increases in LUTS severity in older men over time, independent of age and comorbidities. Results suggest LUTS and frailty share an underlying mechanism that is not targeted by existing LUTS interventions.

The perceived benefit and satisfaction from conventional and complementary and alternative medicine (CAM) in people with multiple sclerosis.

OBJECTIVE: To describe the perceived benefit and satisfaction from complementary and alternative medicine (CAM) and conventional therapies and providers in MS. DESIGN: Cross-sectional mailed survey. SETTING: One thousand nine hundred and thirteen respondents who were members of the Oregon Chapter of the National MS Society. RESULTS: The benefit rating of both conventional therapies and providers was significantly higher than for CAM therapies and providers (p < 0.001 and < 0.001). When stratifying satisfaction rating by MS disease severity, significant differences were found between CAM providers and neurologists, favoring CAM providers in those with moderate disease severity (p = 0.014) and favoring neurologists in those with severe disease severity (p = 0.032). CAM providers were rated significantly higher than MDs on the following: listening skills (p < 0.001), care and concern (p < 0.001), and patient empowerment (p < 0.001). CONCLUSIONS: Although MS patients report significant benefit from conventional therapies and providers; they may seek CAM providers for emotional support. The impact of emotional support gained from providers on quality of life in MS warrant further investigation.

Demographic and health-related factors associated with complementary and alternative medicine (CAM) use in multiple sclerosis.

Complementary and alternative medicine (CAM) use is high among people with multiple sclerosis (MS), yet there are no reports on the association between CAM use and health-related quality of life (HRQL) in MS. To examine this relationship, a cross-sectional survey and SF-12 was used to collect demographic and HRQL data from 1667 survey respondents. Factors examined for their association with CAM use included, age, gender, race, self-reported disease severity, disease-modifying drug (DMT) use, MS duration, MS type, education level, physical and mental well-being. Multiple regression analysis revealed that female gender, high education level, longer MS duration, lower physical well-being and not using DMT were independent factors associated with both 'ever' and 'current' CAM use. The finding that a drop in physical component score (PCS) of the SF-12 is independently associated with an increased odds of 'ever' CAM use, 'current' CAM use, and 'past' CAM reflect an association of CAM use with PCS regardless of time of use. Although, temporality of this relationship cannot be established, as this was a cross-sectional study, a longitudinal study is warranted so that we can establish if HRQL is predictive for CAM use in MS.
