Total serum cholesterol and recovery from disability among hospitalized older adults.

BACKGROUND: The association between total serum cholesterol and health outcomes among older adults is controversial. The objective of the present study was to determine within a cohort of acutely hospitalized disabled elderly patients whether total cholesterol predicts recovery from disability in basic activities of daily living (ADL). METHODS: Patients (3150) 65 years old or older admitted to 81 acute care units in Italy and presenting with ADL disability at hospital admission were included in this study. ADL disability was defined as need of assistance or total dependence in one or more ADLs (eating, dressing, personal hygiene, transferring, and toilet use). Recovery was defined as no disability at hospital discharge in any of the five ADLs considered. RESULTS: Mean age of study participants was 80.5 +/- 7.2 years, and 1305 (41.1%) were men. The rate of recovery from ADL disability was 14.5% for participants with total cholesterol < 200 mg/dL (n = 306/2108), 20.2% for those with total cholesterol between 200 and 239 mg/dL (n = 144/713), and 23.1% for those with total cholesterol > or = 240 mg/dL (n = 76/329). After adjustment for potential confounders, relative to that of patients with cholesterol < 200 mg/dL, risk ratios for recovery were 1.31 for participants with cholesterol between 200 and 239 mg/dL (95% confidence interval [CI], 1.07-1.62) and 1.36 (95% CI, 1.04-1.79) for those with cholesterol > or = 240 mg/dL. After exclusion of 769 patients with total cholesterol < 145 mg/dL, the risk ratios (compared with those for participants with cholesterol < 200 mg/dL) for recovery were 1.33 (95% CI, 1.07-1.66) for participants with cholesterol between 200 and 239 mg/dL and 1.41 (95% CI, 1.06-1.88) for patients with cholesterol > or = 240 mg/dL. CONCLUSIONS: Among hospitalized disabled older adults, elevated levels of cholesterol are associated with increased rate of recovery from ADL disability.

Preoperative assessment and risk factors in the surgical treatment of lung cancer: the role of age.

The incidence of lung cancer in the elderly is increasing in Western countries. This disease represents the second leading cause of cancer death in this age group and it is also responsible for a substantial increment in morbidity and health care costs. Several studies suggested that age per se should not be considered a risk factor for surgical mortality and morbidity in lung cancer patients and access to surgical treatment should not be denied only on the basis of age. Indeed, advanced age may represent an indicator of several factors such as comorbidity or poor physical performance which in turn can increase surgical risk and dramatically reduce life expectancy. Therefore, a careful preoperative assessment of these factors, with particular regard to comorbid conditions (such as cardiovascular and pulmonary diseases or secondary malignancy) is necessary in older adults. In consideration of the need of a multidisciplinary assessment to identify comorbidities and operative risk a close collaboration between pneumologists, radiologists, oncologists, thoracic surgeons, anesthesiologists, cardiologists, geriatric specialists, physical therapists is highly recommended.
