RESUMO
BACKGROUND: Gender differences in stroke functional recovery after rehabilitation are poorly investigated. Our aim was to compare functional outcomes at discharge from an intensive rehabilitation hospital after stroke in men and women, and to analyze their prognostic factors. METHODS: Retrospective observational study of consecutive stroke patients discharged from an intensive neurological rehabilitation hospital, from January 2018 to June 2019. Modified Rankin Scale (mRS) at discharge was the main outcome measure. RESULTS: Among the 208 included patients (mean age 73.4 ± 13.6 years), 105 (50.5%) were women. Women were significantly older (75.3 ± 13.8 vs. 71.4 ± 13.2 years, respectively, p = 0.041), and less often had a history of smoking habit (27% vs. 50%, p < 0.001). No gender differences emerged for vascular risk factors and comorbidities, pre-stroke functional status, length of hospital stay, stroke type, and number of clinical deficits. At admission to the rehabilitation hospital, mRS score distributions were not different (p = 0.795). At discharge, mRS score distributions and destinations did not differ between men and women (p = 0.391, p = 0.785, respectively). A significant interaction between gender and the change in mRS score from admission to discharge was found (F = 6.6, p = 0.011) taking into account age, stroke type, and number of initial clinical deficits. Dividing the cohort according to age, elderly women showed a better functional recovery compared to men. CONCLUSIONS: At admission to an intensive rehabilitation hospital, men and women presented a similar functional and clinical status and a substantial overlap of functional recovery after stroke. At higher ages, the potential for recovery appeared better in women compared to men.

Comparison studies on recovery outcomes in ischemic (IS) and hemorrhagic strokes (HS) have yielded mixed results. In this retrospective observational study of consecutive IS and HS patients, we aimed at evaluating functional outcomes at discharge from an intensive rehabilitation hospital, comparing IS vs. HS, analyzing possible predictors. Modified Rankin Scale (mRS) at discharge was the main outcome. Out of the 229 patients included (mean age 72.9 ± 13.9 years, 48% males), 81 had HS (35%). Compared with IS (n = 148), HS patients were significantly younger (75 ± 12.5 vs. 68.8 ± 15.4 years, p = 0.002), required longer hospitalizations both in acute (23.9 ± 36.7 vs. 35.2 ± 29.9 days, p = 0.019) and rehabilitation hospitals (41.5 ± 31.8 vs. 77.2 ± 51.6 days, p = 0.001), and had more severe initial clinical deficit (mean number of neurological impairments: 2.0 ± 1.1 vs. 2.6 ± 1.4, p = 0.001) and mRS scores at admission (p = 0.046). At discharge, functional status change, expressed as mRS, was not significantly different between IS and HS (F = 0.01, p = 0.902), nor was the discharge destination (p = 0.428). Age and clinical severity were predictors of functional outcome in both stroke types. On admission in an intensive rehabilitation hospital, HS patients presented a worse functional and clinical status compared to IS. Despite this initial gap, the two stroke types showed an overlapped trajectory of functional recovery, with age and initial stroke severity as the main prognostic factors.
RESUMO
BACKGROUND: To standardize assessment and coordinate processes in stroke rehabilitation, an integrated care pathway (ICP) was developed in an Italian Rehabilitation and Research Institution by a knowledge-translation interdisciplinary process, from evidence-based guidelines to rehabilitation practice. The ICP was implemented in two pilot Tuscan rehabilitation Centers. AIM: The purpose of this study was to describe ICP development and assess the ICP effects on postacute stroke inpatient rehabilitation outcomes. DESIGN: Prospective observational study, before and after comparison. SETTING: Two Tuscan inpatient rehabilitation centers. POPULATION: Patients accessing either centers for intensive rehabilitation after acute stroke. METHODS: Two cohorts were prospectively recruited before (2015-2017) and after (2018) implementation of the pathway. The primary outcome was change in activities of daily living disability, assessed by the modified Barthel Index (mBI) from admission to discharge. Secondary outcomes included length of stay (LOS), adverse outcomes, and changes in communication ability, trunk control, pain, ambulation, bladder catheter (Y/N), bedsores (Y/N). RESULTS: In 2015-2017, 443 postacute stroke patients (mean age 77±11 years, 47% women), while in 2018, 84 patients (mean age 76±13 years, 61% women) were admitted to the two facilities. Comparing the 2018 vs. the 2015-17 cohort, the mean mBI increase was not substantially different (26 vs. 24 points), nor were LOS (37±18 vs. 36±16 days), adverse outcomes, discharge destination, and improvement of ambulation, pain, and communication (P>0.05). Instead, a significantly higher improvement of trunk control (trunk control test: 69.6±33.2 vs. 79.0±31.3, P=0.019), and a higher percentage of bedsore resolution (13% vs. 5%, P=0.033), and bladder catheter removal (37% vs. 17% P<0.001) were observed in 2018 vs. 2015-2017. CONCLUSIONS: Compared to prior practice, ICP was associated to improvement of trunk control recovery, bladder catheter removal, and bedsores resolution. Further ICP implementation on a larger scale is needed to verify improvements of stroke inpatient rehabilitation outcomes. CLINICAL REHABILITATION IMPACT: An evidence-based stroke rehabilitation ICP was interdisciplinary developed and implemented in two rehabilitation centers of a multicenter Italian health group. ICP implementation as to inpatient intensive postacute stroke rehabilitation was associated to improved trunk control recovery, bladder catheter removal, and bedsore resolution. Further ICP implementation will allow multicenter studies and quality benchmarking.

The objective of this prospective randomized controlled study was to compare the long-term effects of a structured physical activity intervention with those of aerobic exercises alone, in a cohort of elderly patients who had undergone elective cardiac surgery, and who were classified as frail at the end of rehabilitation based on their Short Physical Performance Battery (SPPB) score. At the end of rehabilitation, 140 frail elderly patients were randomly allocated either to the intervention group (IG) or to the control group (CG). CG participants received the usual aerobic exercise prescription, while IG participants were also taught additional exercises for strength, flexibility, balance and coordination. The improvement in SPPB score after 1 year was the outcome of the study. IG showed a significant improvement in SPPB score (9.0 ± 1.1 vs. 7.7 ± 1.4, p < 0.001), while no significant change was found in CG (7.7 ± 1.6 vs. 7.6 ± 1.5, p = 0.252). IG also showed a significantly higher proportion of participants who improved their SPPB score of at least 1 point (70 vs. 37%, p < 0.001). In conclusions, our structured physical activity intervention significantly improves the SPPB score in frail elderly patients who have undergone elective cardiac surgery. An intervention that improves the SPPB score might delay the occurrence of mobility disability.

BACKGROUND: To walk a given distance older persons consume more metabolic energy than younger adults across all speeds. As physical activity interventions improve a variety of physical performance measures in older persons, including walking speed, in this study we hypothesized that the improvement of walking speed might be associated with the reduction of the metabolic cost of walking and we tested our hypothesis in a selected sample of older patients receiving cardiac rehabilitation. METHODS: In 120 patients (88 men and 32 women, mean age 74.1 years±SD 5.0) we assessed energy expenditure during the 6-min Walk Test (6mWT) before and after the rehabilitation using a portable system for direct calorimetry. RESULTS: On the 6mWT performed after the rehabilitation patients significantly increased total energy expenditure (28.0 kcal±SD 8.3 vs. 25.7 kcal±SD 7.6, p<0.001), the distance walked (398 m±SD 93 vs. 343 m±SD 95, p<0.001) and, consequently, walking speed (1.11 m/s±SD 0.26 vs. 0.95m/s±SD 0.26, p<0.001) while the metabolic cost of walking, i.e. the amount of energy used to move a body mass of 1 kg for a distance of 1m, was significantly reduced (1.00 cal/kg/m±SD 0.19 vs. 1.11 cal/kg/m±SD 0.32, p<0.001). CONCLUSIONS: In older patients receiving cardiac rehabilitation the improvement of walking speed is associated with the improvement of walking economy. This might be a contributory factor to the favourable effects of physical activity interventions on physical performance measures.

OBJECTIVE: Postoperative atrial fibrillation (AF) is a frequent complication after cardiac surgery. AF may also occur after hospital discharge during postacute rehabilitation. Several studies have addressed the AF that occurs in the hospital after surgery, and predictors have already been identified. Postoperative AF that occurs after hospital discharge has not been investigated thoroughly, and predictors are still unknown. In this study, we hypothesized that moderate-intensity physical activity in the year before surgery might favorably affect the incidence of AF during postacute rehabilitation. DESIGN: We tested our hypothesis in a cohort of 158 older patients admitted to a medical rehabilitation facility for postacute inpatient rehabilitation after coronary surgery and continuously monitored by telemetry for the duration of the rehabilitation. RESULTS: Independent of potential confounders, patients who reported low-intensity physical activity in the year before surgery showed a significantly higher incidence of AF during postacute rehabilitation when compared with those who reported moderate-intensity physical activity (32.1% vs. 8.1%; P = 0.029). Other independent predictors of AF during postacute rehabilitation were the occurrence of AF during the patients' stay in hospital, larger left atrial volume, and lower left atrial emptying fraction. CONCLUSIONS: These findings confirm our hypothesis that physical activity in the year before surgery affects the incidence of postoperative AF during postacute rehabilitation. The results also provide information regarding possible predictors that may assist in identifying patients who could benefit from preventive treatments.

OBJECTIVE: Older patients who receive postacute cardiac rehabilitation improve their physical performance in terms of distance walked at the 6-min walk test. However, the slower and more complicated recovery, along with age-related chronic comorbidities, remarkably limits the intensity of aerobic training, which actually represents the core of cardiac rehabilitation. The aim of this study was to verify whether postacute cardiac rehabilitation also improves the cardiovascular adjustment to exercise, despite low-intensity aerobic training. DESIGN: Using a portable gas analyzer, we assessed the O(2) uptake kinetics during the 6-min walk test at the beginning and at the end of the rehabilitation in 84 patients aged 65 yrs and above. RESULTS: All patients significantly improved the distance walked at the 6-min walk test. The comparison of the time constants of O(2) uptake kinetics showed that 40% of patients also significantly improved the hemodynamic response to exercise. This improvement was independently associated with the report of sedentary lifestyle or low-intensity physical activity in the year before surgery and with longer time constants before physical training. CONCLUSIONS: Low-intensity aerobic training improves the cardiovascular adjustment to exercise selectively in patients with physical deconditioning. This confirms the notion that elderly frail patients are those who benefit most from cardiac rehabilitation.

OBJECTIVE: Promoting an active lifestyle through an appropriate physical exercise prescription is one of the major targets of cardiac rehabilitation. However, information on the effectiveness of cardiac rehabilitation in promoting lifestyle changes in elderly patients is still scant. DESIGN: In 131 patients over the age of 65 yrs (86 men, and 45 women, mean age 75 yrs +/- 6 SD) who have attended postacute inpatient cardiac rehabilitation after cardiac surgery, we tested the 1-yr adherence to the physical exercise prescription received at the end of the cardiac rehabilitation by using a questionnaire on physical activity and the 6-min walk test. RESULTS: All of the 36 patients who reported an active lifestyle and 49 of the 95 patients who reported a sedentary lifestyle in the year preceding the cardiac operation reported at least 1 hr/day on 5 days each week of light regular physical activity in the year after the cardiac rehabilitation. Further, the distance walked at the follow-up 6-min walk test was significantly related to the physical activity score gathered from the questionnaire. CONCLUSIONS: Our data show that 65% of the elderly patients who have attended postacute inpatient cardiac rehabilitation after cardiac surgery are still capable of recovering or even increasing their regular physical activity and of maintaining these favorable lifestyle changes at least for 1 yr.

BACKGROUND: Previous studies have shown that oxidative protein damage is independently associated with low grip strength and that dietary intake and circulating levels of antioxidant vitamins are positive predictors of muscle strength among older persons. Since uric acid (UA), has strong antioxidant properties, we tested the hypothesis that UA levels is cross-sectionaly associated with muscle strength and protective against the decline of strength over the aging process. SUBJECTS AND METHODS: 789 InCHIANTI Study participants underwent baseline serum UA, handgrip and knee extension torque measurements. Of these, 497 participants (226 men and 271 women, mean age 76.0+/-5.4 years) also had follow-up strength measures. Lifestyle, comorbidities, nutritional profile, inflammatory markers and other laboratory measures were considered as potential confounders. RESULTS: Follow-up strength measures significantly increased across baseline UA tertiles. After adjusting for potential confounders and analogous baseline strength measures, higher baseline UA levels still remained significantly associated with higher follow-up strength measures. CONCLUSIONS: Our findings suggest that higher levels of UA might represent a protective reaction aimed at counteracting the excessive production of free radicals that cause muscle protein damage and eventually contribute to the decline of muscle mass and strength.

OBJECTIVE: The 6-min walk test (6mWT) is widely used to assess physical performance in cardiac rehabilitation settings. Factors affecting the walked distance before starting physical training have been described, whereas information on factors affecting the increase of the walked distance after physical training is still scant. The aim of this study was to verify, in a large sample of elderly patients soon after cardiac surgery, the role of left-ventricular function (LVF) in increases in distances walked after an intensive rehabilitation program. DESIGN: We enrolled 459 patients (300 males and 159 females, mean [+/-SD] age 70 +/- 11 yrs). According to the echographic ejection fraction, patients were classed into two categories, LVF > or = 40% and LVF < 40%. All patients performed the 6mWT at the beginning and end of the rehabilitation program. RESULTS: Longer walked distances before and after the rehabilitation program were significantly associated with preserved or moderately depressed LVF, whereas greater relative increases of the distance walked after the rehabilitation program were significantly associated with poor LVF (P < 0.001 for all). CONCLUSIONS: Among elderly patients admitted as inpatients to an intensive rehabilitation program soon after cardiac surgery, those with poor LVF are most likely to respond more favorably to physical training. Therefore, instead of considering poor LVF a risk for starting physical training in these patients, it should be considered a strong indication, to avoid further physical deconditioning and disability.
