Background: Total cholesterol is significantly associated with increased risk of ischemic stroke. Patients with ischemic stroke and high cholesterol levels may show better functional outcome after rehabilitation.

Objectives: To study the possible interrelations between hypercholesterolemia and functional outcome in elderly survivors of ischemic stroke.

Methods: We conducted a retrospective chart review study of consecutive patients (age ≥ 60 years) with acute stroke admitted to a geriatric rehabilitation ward in a university-affiliated hospital. The presence or absence of hypercholesterolemia was based on registry data positive for hypercholesterolemia, defined as total cholesterol ≥ 200 mg/dl (5.17 mmol/L). Functional outcome of patients with hypercholesterolemia (Hchol) and without (NHchol) was assessed by the Functional Independence Measurement scale (FIMTM) at admission and discharge. Data were analyzed by t-test and chi-square test, as well as linear regression analysis.

Results: The complete data for 551 patients (age range 60–96 years)w ere available for final analysis; 26.7% were diagnosed as having hypercholesterolemia. Admission total FIM[1] scores were significantly higher in patients with Hchol[2] (72.1 ± 24.8) compared with NHchol[3] patients (62.2 ± 24.7) (P < 0.001). A similar difference was found at discharge (Hchol 90.8 ± 27.9 vs. NHchol 79.7 ± 29.2, P < 0.001). However, total FIM change upon discharge was similar in both groups (18.7 ± 13.7 vs. 17.6 ± 13.7, P = 0.4). Regression analyses showed that high Mini Mental State Examination scores (β = 0.13, P = 0.01) and younger age (β = -0.12, P = 0.02) were associated with higher total FIM change scores upon discharge. Total cholesterol was not associated with better total FIM change on discharge (β = -0.012, P = 0.82).

Conclusions: Elderly survivors of stroke with Hchol who were admitted for rehabilitation showed higher admission and discharge FIM scores but similar functional FIM gains as compared to NHchol patients. High cholesterol levels may be useful in identifying older individuals with a better rehabilitation potential.

Background: A high total plasma homocysteine level is an independent risk factor for cardiovascular and cerebrovascular disease, but the evidence connecting plasma tHcy level with hypertension is inconsistent.

Objective: To determine the association between plasma tHcy level and some common risk factors for cerebrovascular disease (recurrent  stroke, diabetes mellitus, hypertension, ischemic heart disease and hyperlipidemia) in patients presenting with primary or recurrent acute ischemic strokes.

Methods: This retrospective cross-sectional chart analysis was conducted in a university-affiliated referral hospital. During an 18 month period we identified 113 acute ischemic stroke patients (mean age 71.2), 25 of whom had a recurrent stroke. Plasma tHcy[1] level, obtained 2–10 days after stroke onset, was determined by the high performance liquid chromatography method with fluorescence detection. A multivariate logistic regression model was used to determine the independent relationship between each potential risk factor and tHcy level above or below the 75th percentile.

Results:  Hypertension was more frequent among patients with plasma tHcy level above than below the 75th percentile (51.7% vs. 80.8%, respectively, P = 0.012). After adjusting for demographic and clinical variables, the odds ratio for recurrent stroke and hypertension, with tHcy above or below the 75th percentile, was 3.4 (95% confidence interval 1.01–10.4, P = 0.037) and 4.02 (95% CI[2] 1.2–13.9, P = 0.028), respectively.

Conclusions: A high plasma tHcy level is associated with history of hypertension and recurrent stroke among patients presenting with acute ischemic stroke. These results were independent of other risk factors such as atrial fibrillation, diabetes and hyperlipidemia. Hypertensive stroke patients with hyperhomocysteinemia should be identified as high risk patients as compared to non-hypertensive stroke patients, and may warrant more vigorous measures for secondary prevention.

Background: The progressive increase in the number of elderly patients with hip fractures and the particular multidisciplinary needs of this population call for the investigation of other models of orthogeriatric care.

Objectives: To describe the nature and assess the feasibility of a comprehensive orthogeriatric unit attending to patients' surgical, medical and rehabilitation needs in a single setting.

Methods: This retrospective chart review describes consecutive older patients with hip fractures admitted directly from the emergency ward to an orthogeriatric ward.

Results: The mean age of the 116 patients evaluated was 82.4 years. Delay to surgery was 3.6±3.1 days and total length of stay 23.9±11.0 days. No patient was transferred to other acute medical wards of the hospital and 66.4% were able to return to their previous living place. Rates of major complications and mortality were extremely low.

Conclusion: The present model of a comprehensive orthogeriatric ward is a practical, applicable and feasible service for elderly hip fracture patients and can cover the various needs of these patients. The deployment arrangements needed to establish and operate the ward were minimal and there were only a few management and organizational problems. The cost-effectiveness and other comparative benefits of this type of service have yet to be clarified.
