Polypharmacy, common in older people, confers both risk of adverse outcomes and benefits. We assessed the relationship of commonly prescribed medications with anticholinergic and sedative effects to physical and cognitive performance in older individuals. The study population comprised 932 moderately to severely disabled community-resident women aged 65 years or older who were participants in the Women's Health and Aging Study I. A scale based on pharmacodynamic principles was developed and utilized as a measure of drug burden. This was related to measures of physical and cognitive function. After adjusting for demographics and comorbidities, anticholinergic drug burden was independently associated with greater difficulty in four physical function domains with adjusted odds ratios (95% confidence interval (CI)) of 4.9 (2.0-12.0) for balance difficulty; 3.2 (1.5-6.9) for mobility difficulty; 3.6 (1.6-8.0) for slow gait; 4.2 (2.0-8.7) for chair stands difficulty; 2.4 (1.1-5.3) for weak grip strength; 2.7 (1.3-5.4) for upper extremity limitations; 3.4 (1.7-6.9) for difficulty in activities of daily living; and 2.4 (95% CI, 1.1-5.1) for poor performance on the Mini-Mental State Examination. Sedative burden was associated only with impaired grip strength (3.3 (1.5-7.3)) and mobility difficulty (2.4 (1.1-5.3)). The burden of multiple drugs can be quantified by incorporating the recommended dose regimen and the actual dose and frequency of drug taken. Anticholinergic drug burden is strongly associated with limitations in physical and cognitive function. Sedative burden is associated with impaired functioning in more limited domains. The risk associated with exposure of vulnerable older women to drugs with anticholinergic properties, and to a lesser extent those with sedative properties, implies that such drugs should not be used in this patient group without compelling clinical indication.

Aim To evaluate whether the presence of apical periodontitis (AP), root canal treatment (RCT) and endodontic burden (EB) – as the sum of AP and RCT sites – were associated with long-term risk of incident cardiovascular events (CVE), including cardiovascular-related mortality, using data on participants in the Baltimore Longitudinal Study of Aging (BLSA). Methodology This retrospective cohort included 278 dentate participants in the BLSA with complete medical and dental examinations. Periodontal disease (PD) and missing teeth were recorded. Total number of AP and RCT sites was determined from panoramic radiographs. EB was calculated as the sum of AP and RCT sites. Oral inflammatory burden (OIB) was calculated combining PD and EB. The main outcome was, incident CVE including angina, myocardial infarction and cardiovascular-related death. Participants were monitored for up to 44 years (mean=17.4±11.1 years) following dental examination. Relative Risks (RR) were calculated through Poisson regression models, estimating the relationship between AP, RCT, EB, PD, OIB and incident CVE. Results Mean age at baseline was 55.0±16.8 years and 51.4% were men. Sixty two participants (22.3%) developed CVE. Bivariate analysis showed that PD, EB, number of teeth and OIB were associated with incident CVE. Multivariate models, adjusted for socio-demographic and medical variables, showed that age≥60 years (RR=3.07, 95%CI=1.68-5.62), hypertension (RR=2.0, 95%CI=1.16-3.46) and EB≥3 (RR=1.77, 95%CI=1.04-3.02) were independently associated with incident CVE. The association between OIB and incident CVE was reduced to non-significance after adjustments (RR=1.97, 95%CI=0.83-4.70). Conclusions EB in mid-life was an independent predictor of CVE among community-dwelling participants in the BLSA. Prospective studies are required to evaluate cardiovascular risk reduction with the treatment of AP.
