Nutritional Prehabilitation in Patients Undergoing Cystectomy: A Systematic Review.

BACKGROUND/AIM: Nutrition is a key element of the prehabilitation process prior to surgery. The aim of this study was to identify the clinical pathways of nutritional prehabilitation before cystectomy. METHODS: A systematic literature review was conducted in PubMed, the Cochrane Library, CINAHL, Scopus and the Web of Science databases. Quality and risk of bias assessment was conducted adhering to the JBI framework and evidence was evaluated according to the Oxford Centre for Evidence Based Medicine levels of evidence. RESULTS: Out of 586 records identified, six studies were included. Among them, only two were randomized controlled trials. Immunonutrition has been shown to improve postoperative bowel function (3.12 vs. 3.74 days; RR 0.82; CI, 0.73-0.93; p = 0.0029) and decrease postoperative complications (-36.7%; p = 0.008) and readmission rates (-15.38%; p = 0.03). Furthermore, oral nutritional supplements combined with nutritional counseling demonstrated an accelerated recovery of bowel function (-1 day; p < 0.01), a reduction in the length of hospital stay (-1.75 days; p = 0.01), an improvement in handgrip strength (+6.8%, p < 0.001), an increase in bone mass (+0.3 kg, p = 0.04), and a better BMI value (+2.3%, p = 0.001). CONCLUSIONS: Nutritional prehabilitation demonstrates potential in enhancing postoperative outcomes following radical cystectomy. Oral supplements, immunonutrition, and counseling exhibit efficacy in improving postoperative results.

A multicenter prospective study validated a nomogram to predict individual risk of dependence in ambulation after rehabilitation.

OBJECTIVES: To develop the Functional Risk Index for Dependence in Ambulation (FRIDA) score, a nomogram to predict individual risk of dependence in ambulation at discharge from postacute rehabilitation and validate its performance temporally and spatially. STUDY DESIGN AND SETTING: We analyzed the database of a multicenter prospective observational quality cohort study conducted from January 2012 to March 2016, including data from 8,796 consecutive inpatients who underwent rehabilitation after stroke, hip fracture, lower limb joint replacement, debility, and other neurologic, orthopedic, or miscellaneous conditions. RESULTS: A total of 3,026 patients (34.4%) were discharged dependent in ambulation. In the training set of 5,162 patients (58.7%), Lasso-regression selected advanced age, premorbid disability, and eight indicators of medical and functional adverse syndromes at baseline to establish the FRIDA score. At the temporal validation obtained on an external set of 3,234 patients (41.3%), meta-analyses showed that the FRIDA score had good and homogeneous discrimination (summary area under the curve 0.841, 95% confidence interval = 0.826-0.855, I2 = 0.00%) combined with accurate calibration (summary Log O/E ratio 0.017, 95% confidence interval -0.155 to 0.190). These performances remained stable at spatial validation obtained on 3,626 patients, with substantial heterogeneity of estimates across nine facilities. Decision curve analyses showed that a FRIDA score-supported strategy far outperformed the usual "treat all" approach in each impairment categories. CONCLUSION: The FRIDA score is a new clinically useful tool to predict an individual risk for dependence in ambulation at rehabilitation discharge in many different disabilities, and may also reflect well the case-mix composition of the rehabilitation facilities.

Microstructural characterization of corticospinal tract in subacute and chronic stroke patients with distal lesions by means of advanced diffusion MRI.

PURPOSE: The aim of the paper is to evaluate if advanced dMRI techniques, including diffusion kurtosis imaging (DKI) and neurite orientation dispersion and density imaging (NODDI), could provide novel insights into the subtle microarchitectural modifications occurring in the corticospinal tract (CST) of stroke patients in subacute and chronic phases. METHODS: Seventeen subjects (age 68 ± 11 years) in the subacute phase (14 ± 3 days post-stroke), 10 of whom rescanned in the chronic phase (231 ± 36 days post-stroke), were enrolled. Images were acquired using a 3-T MRI scanner with a two-shell EPI protocol (20 gradient directions, b = 700 s/mm2, 3 b = 0; 64 gradient directions, b = 2000 s/mm2, 9 b = 0). DTI-, DKI-, and NODDI-derived parameters were calculated in the posterior limb of the internal capsule (PLIC) and in the cerebral peduncle (CP). RESULTS: In the subacute phase, a reduction of FA, AD, and KA values was correlated with an increase of ODI, RD, and AK parameters, in both the ipsilesional PLIC and CP, suggesting that increased fiber dispersion can be the main structural factor. In the chronic phase, a reduction of FA and an increase of ODI persisted in the ipsilesional areas. This was associated with reduced Fic and increased MD, with a concomitant reduction of MK and increase of RD, suggesting that fiber reduction, possibly due to nerve degeneration, could play an important role. CONCLUSIONS: This study shows that advanced dMRI approaches can help elucidate the underpinning architectural modifications occurring in the CST after stroke. Further follow-up studies on bigger cohorts are needed to evaluate if DKI- and NODDI-derived parameters might be proposed as complementary biomarkers of brain microstructural alterations.

Association between delirium, adverse clinical events and functional outcomes in older patients admitted to rehabilitation settings after a hip fracture: A multicenter retrospective cohort study.

AIM: The aim of the present study is to investigate how delirium and adverse clinical events (ACE) contribute independently and in combination to functional outcomes in older patients admitted to rehabilitation settings after a hip fracture. METHODS: This is a multicenter retrospective cohort study of patients aged ≥65 years admitted after hip fracture surgical repair to three Italian rehabilitation units. Delirium on admission was evaluated with the Confusion Assessment Method. ACE during the rehabilitation stay were recorded, including infections (i.e. urinary tract infections, other infections), non-infectious ACE (i.e. cardiovascular events, respiratory failure, pulmonary embolism) and falls. A multivariable linear regression was used to evaluate the effect of ACE and delirium on functional outcome, adjusting for covariates determined a priori. RESULTS: A total of 519 patients were included in the study. The mean ± SD age was 82.9 ± 9.4 years. ACE occurred in 277 patients (53.4%), delirium alone was present in 19 patients (3.6%). Both conditions were present in 58 patients (11.2%). Compared with patients without delirium or ACE, those with ACE or delirium were more likely to have a worse functional outcome (-6.7 Barthel Index points [-11.6; -1.7]; P = 0.008; -13.2 [-25.6; -0.8]; P = 0.038) at discharge, and patients with both conditions had an even lower Barthel Index score (-18.6 Barthel Index points [-26.9; -10.3]; P < 0.001). CONCLUSIONS: ACE and delirium are very common in older patients admitted to rehabilitation settings after hip fracture, and frequently coexist. As both ACE and delirium could impact on functional outcome, alone and in combination, a clinical geriatric approach is necessary for this population to minimize risks.

A score to predict the development of adverse clinical events after transition from acute hospital wards to post-acute care settings.

Adverse clinical events (ACEs) are common in post-acute hospital care. We aimed at developing and validating a method, able to be administered in hospital wards, for identifying elderly patients at increased risk of ACEs after transferral to post-acute care (PAC) facilities. This was a prospective observational study, including 502 patients admitted to 19 PAC facilities in northern Italy from July 1(st) to August 14(th), 2009. A standardized form was used to collect data. Variables showing stable association with ACEs in testing group were used to derive the score. The relative risk (RR) of developing ACEs according to the score was measured in the validation group. Age ≥87 years, delirium, pressure sore, indwelling bladder catheter, malnutrition, and acute infection on admission were identified as stable ACE predictors. A score of 1 was assigned to each predictor. Subjects were classified as having low (score=0), medium-low (score=1), medium-high (score=2-3), or high (score ≥4) risk of ACEs. The RR of developing ≥1 ACE increased progressively from low (RR=1) to medium-low (RR=1.5, 95% confidence interval [CI] 1.1-1.9), medium-high (RR=1.6, 95% CI 1.3-2.1), and high (RR=1.8, 95% CI 1.4-2.3) risk score. The RR of being not discharged to home increased monotonically from 1.0 in low-risk to 2.7 in high-risk groups. In conclusion, this study proposes a method, able to be administered in hospital wards, for identifying patients at increased risk of ACEs after transferral to PAC. The score might also be used to identify people who will not return to home after PAC discharge.

Action observation treatment improves recovery of postsurgical orthopedic patients: evidence for a top-down effect?

OBJECTIVE: To assess whether action observation treatment (AOT) may also improve motor recovery in postsurgical orthopedic patients, in addition to conventional physiotherapy. DESIGN: Randomized controlled trial. SETTING: Department of rehabilitation. PARTICIPANTS: Patients (N=60) admitted to our department postorthopedic surgery were randomly assigned to either a case (n=30) or control (n=30) group. Exclusion criteria were age 18 years or younger and 90 years or older, Mini-Mental State Examination score of 21 of 30 or lower, no ambulating order, advanced vision impairment, malignancy, pneumonia, or heart failure. INTERVENTIONS: All participants underwent conventional physiotherapy. In addition, patients in the case group were asked to observe video clips showing daily actions and to imitate them afterward. Patients in the control group were asked to observe video clips with no motor content and to execute the same actions as patients in the case group afterward. Participants were scored on functional scales at baseline and after treatment by a physician blinded to group assignment. MAIN OUTCOMES MEASURES: Changes in FIM and Tinetti scale scores, and dependence on walking aids. RESULTS: At baseline, groups did not differ in clinical and functional scale scores. After treatment, patients in the case group scored better than patients in the control group (FIM total score, P=.02; FIM motor subscore, P=.001; Tinetti scale score, P=.04); patients in the case group were assigned more frequently to 1 crutch (P=.01). CONCLUSIONS: In addition to conventional physiotherapy, AOT is effective in the rehabilitation of postsurgical orthopedic patients. The present results strongly support top-down effects of this treatment in motor recovery, even in nonneurologic patients.
