[Older emergency patients in the emergency department : A key performance indicator analysis based on the DIVI emergency department protocol]. / Ältere Notfallpatienten in der zentralen Notaufnahme : Eine Kennzahlenauswertung auf Basis des DIVI-Notaufnahmeprotokoll.

BACKGROUND: Overall, there is only little data in health care research on the subject of emergency care in older patients in Germany. The aim of the present study is to assess the older emergency patient in regard to the core data set "Emergency Department" of the German Interdisciplinary Association for Intensive Care and Emergency Medicine (DIVI). MATERIALS AND METHODS: Monocentric, retrospective observational study. RESULTS: In the observation period, a total of 29,391 emergency patients were treated at the interdisciplinary emergency center. Of these, 8072 emergency patients were ≥65 years old (27.4%). With increasing age, paramedic ambulances (RTW) or physician-led ambulances (NEF) are increasingly used (p < 0.001). Older emergency patients arriving by a physician-led emergency service show a 38.9-fold increase in mortality compared to ambulatory patients (odds ratio = 38.98 [29.22-51.87]). The initial assessment, using the Manchester Triage System (MTS), shows a steady rise towards higher urgency levels with increasing age (p < 0.001). In the multivariate analysis within the individual age clusters, there is a correlation between the triage level and hospital mortality, unrelated to gender (p < 0.001). Likewise the use of consulting physicians can be linked to advanced age (p < 0.001). Also the length of stay in the interdisciplinary emergency center correlates highly with age (p < 0.001). CONCLUSION: The older emergency patient clearly differs from younger emergency patients in all key performance indicators considered and already poses a special challenge to emergency departments.

Can angiotensin-converting enzyme inhibitors impact cognitive decline in early stages of Alzheimer's disease? An overview of research evidence in the elderly patient population.

Alzheimer's disease (AD) is a neurodegenerative disease, in which an accumulation of toxic amyloid beta in the brain precedes the emergence of clinical symptoms. AD spectrum consists of presymptomatic, early symptomatic, and symptomatic phase of dementia. At present, no pharmacotherapy exists to modify or reverse a course of AD, and only symptomatic treatments are available. Many elderly patients, diagnosed with multiple medical conditions (such as cardiovascular diseases, Type 2 diabetes mellitus, and cerebrovascular diseases) are at increased risk of the development of mild cognitive impairment (MCI), AD, and vascular dementia. Studies have revealed reduced rates of cognitive decline, in elderly patients, who were treated with centrally active angiotensin-converting enzyme inhibitors (ACE-Is) (that have an ability to cross the blood-brain barrier). This article reviews recently published literature, focused on possible protective influence of the centrally active ACE-Is, in the elderly population, at risk for cognitive decline.

Association between anthropometric obesity measures and coronary artery disease: a cross-sectional survey of 16,657 subjects from 444 Polish cities.

BACKGROUND: Excessive body weight is known to cluster with cardiovascular (CV) risk factors, but it is not clear which anthropometric obesity measure provides best independent predictive value of coronary artery disease (CAD). METHODS AND RESULTS: We explored associations between CAD and four different obesity measures (body mass index (BMI), waist circumference, waist/height and waist/height(2)) in a cohort of 16 657 subjects (40.4% men; 20.8% CAD patients), recruited by 700 primary care physicians in 444 Polish cities. 42.8% of subjects were classified as overweight, 31.7% as obese and 39.8% had abdominal obesity. In univariate analyses all obesity measures correlated with CAD (p>0.001), but waist/height(2) was the strongest discriminator between CAD patients and controls. Age-adjusted and sex-adjusted analyses confirmed a graded increase in CAD risk across distributions of all four obesity measures-1 standard deviation (SD) increase in BMI, waist, waist/height and waist/height(2) increased the odds of CAD by 1.23, 1.24, 1.26 and 1.27, respectively (all p<0.001). In models fully adjusted for CV risk factors, waist/height(2) remained the strongest obesity correlate of CAD, being the only independent associate of CAD in men. In a fully adjusted BMI-waist circumference stratified model, sarcopenic obesity (waist > median, BMI < median) and simple obesity (waist and BMI > median) were the strongest independent associates of CAD in men (p = 0.008) and women (p>0.001), respectively. CONCLUSION: This cross-sectional study showed that waist/height(2) may potentially offer a slightly higher predictive value of CAD than BMI or waist circumference and revealed an apparent sexual dimorphism in correlations between obesity measures and CAD.
