RESUMEN
BACKGROUND: Peripheral arterial disease (PAD) is a common cardiovascular pathology affecting mobility in elderly. Osteoarticular diseases (ODs), responsible for functional limitations and confounding leg symptoms, may interfere with exercise therapy. This study evaluates the feasibility and effectiveness of a structured home-based exercise programme on rehabilitative outcomes in a cohort of elderly PAD patients with and without coexisting ODs. PATIENTS AND METHODS: Patients were enrolled from 2002 to 2016 in an exercise programme prescribed and controlled at the hospital and based on two daily 10-minute home walking sessions below the self-selected speed. The presence and localization of ODs at baseline were derived from consultation of medical documents. The ankle-brachial index and functional outcomes, defined as speed at the onset of claudication and attainable maximal speed by an incremental treadmill test, were assessed at baseline and discharge. Feasibility was determined according to dropout rate, number of visits, duration of the programme, and adherence. RESULTS: A total of 1,251 PAD patients were enrolled (931 men; 71 ± 9 years; 0.63 ± 0.19 ankle-brachial index). Eight hundred sixty-four patients were free of ODs (ODfreePAD, 69 %), whereas 387 were affected by ODs (ODPAD, 31 %), predominantly located in the spine (72 %). In the logistic regression models, the presence of ODs was associated with female sex, overweight, sedentary and/or driving professions. At discharge, ODPAD and ODfreePAD did not differ in dropout rates (12 % each), programme duration (378 ± 241 vs. 390 ± 260 days), number of visits (7 ± 3 each), and adherence (80 % each). Similar improvements for ODPAD and ODfreePAD were observed for the ankle-brachial index (0.06 ± 0.12 each), the speed at onset of claudication (0.7 ± 0.7 vs. 0.7 ± 0.8 kmh-1; p = 0.70), and maximal speed (0.4 ± 0.6 vs. 0.4 ± 0.6 kmh-1; p = 0.77). CONCLUSIONS: Equally satisfactory rehabilitative outcomes were observed in elderly patients with claudication limited by ODs who completed a well-tolerated, low-impact structured exercise programme.

Traumatic brain injury (TBI) is the leading cause of death and disability in young adults. Growth hormone-insulin-like growth factor I (GH-IGF-I) system has an important role in the recovery of the central nervous system. The aim of the study was to evaluate the relationship between pituitary function (in particular, the GH-IGF-I axis) and outcome from TBI. We studied 72 patients (56 males; mean age 37.2 +/- 1.8 years) receiving rehabilitation after TBI. According to the Glasgow Coma Scale (GCS), 10 patients had moderate and 52 severe TBI. Ten patients had growth hormone GH deficiency (GHD), 10 LH-FSH, three TSH, and three ACTH deficiency. Overall pituitary dysfunction occurred in 22 (30.5%) patients, with anterior hypopituitarism in 19 (26.4%), isolated diabetes insipidus in one, and isolated hyperprolactinemia in two. GH response to GHRH + ARG (arginine) positively correlated with Functional Independence Measure (FIM D; r = 0.267, p < 0.02) and Level of Cognitive Functioning Scale (LCFS D; r = 0.287, p < 0.01) at discharge, and negatively with Disability Rating Score at discharge (DRS D; r = -0.324, p < 0.005). Unfavorable outcome measures (FIM D, LCFS D, and DRS D) occurred in patients with hypopituitarism as compared with normal pituitary function (p < 0.05). Multiple regression analysis identified both GCS (p < 0.005) and GH peak (p < 0.05) as strong independent predictors of outcome. In conclusion, recovery after TBI may be negatively influenced by concomitant pituitary dysfunction. The GH peak value is an independent predictor of outcome, indicating that recovery during an intensive rehabilitation program after TBI may be positively influenced by normal GH secretion.
