Inflammation, pressure ulcers and poor functional status predict negative rehabilitation outcomes in postacute geriatric patients.

The purposes of this retrospective study were to document the prevalence of serum C-reactive protein (CRP), a biomarker of inflammation, and its potential predictive value for Rehabilitation outcomes in post-acute elderly inpatients. The medical records of 304 elderly subjects admitted to our Rehabilitation Institute for any disease following an acute event were examined. High levels of CRP (> 0.5 mg/dl) were present in 100% of the subjects, and the value > 1.5 mg/dl (n = 86) predicted unfavourable outcomes (n = 28; 32.5% of the patients: death or transfer to other institutions). Among the patients with favourable outcomes (discharge home n = 255), 62.7% still exhibited severe disabilities. Pressure ulcers and low functional status also predicted unfavourable outcomes. The study highlights the need for future investigations into the possible reduction of CRP levels, after an intensive nutritional approach and combined physical interventions.

The role of lipid profile in determining the risk of ischemic stroke in the elderly: a case-control study.

In this study, we investigated the association of lipids with ischemic stroke and its different subtypes in elderly patients. In particular, lipid parameters not extensively investigated so far in previous case-control studies specifically focused in the old population, such as lipoprotein Lp (a) and Apoproteins AI (ApoAI) and B (ApoB), have been taken into account. Seventy nine patients (mean age 83 +/- 7.4, range 67-99), consecutively admitted to a Geriatric Ward between January 1998 and June 2000 with acute stroke (first event) were studied. A complete clinical and laboratory assessment, including neurological evaluation, head CT scan, carotid ultrasonography and ECG, was employed to define the clinical and etiologic stroke subtype, according to standardized criteria. Fasting blood samples were collected within 48 h from admission, for determination of total cholesterol (TC), triglycerides (TG), High Density Lipoprotein-cholesterol (HDL-C), Lp(a), ApoAI and ApoB; Low Density Lipoprotein-Cholesterol (LDL-C) was estimated by Friedwald formula. Eighty eight age and sex-matched outpatients, referred to the hospital for non-inflammatory disorders of joints and musculoskeletal system, served as controls. Patients showed HDL-C and HDL-C/ApoAI ratio significantly lower than controls, with higher LDL-C/HDL-C ratio. Analysis on quartiles of lipoprotein concentrations showed also a significant increase in odds of stroke for LDL-C concentrations over 100 mg/dl, in absence of a linear relationship between LDL-C levels and risk. Multiple logistic regression, adjusting for non-lipid risk factors for stroke, confirmed the independent association of low HDL-C and HDL-C/ApoAI with all strokes, as well as with each subtype. In conclusion, these data suggest that lipids give some contribution to stroke risk even in the elderly, with a more prevalent role for HDL than LDL, and that lipid profile assessment must be taken into account in estimating the individual risk of stroke.
