RESUMO
BACKGROUND: Patients with peritoneal carcinomatosis often suffer from loss of skeletal muscle mass and require extensive surgery. Multimodal prehabilitation may improve physical status but its benefits for these specific patients remain unknown. This study aimed to evaluate the effect of prehabilitation on functional walking capacity and skeletal muscle mass, as well as its association with postoperative complications. PATIENTS AND METHODS: A prospective study of patients with peritoneal carcinomatosis following a home-based trimodal prehabilitation program was carried out. Functional walking capacity was assessed with the 6-min walk test (T6MWT), and by the appendicular skeletal muscle index (ASMI) estimated by bioelectrical impedance analysis. Data were collected at the first medical appointment and on the day before surgery. A 90-day postoperative morbidity was registered according to the Clavien-Dindo classification. RESULTS: A total of 62 patients were included in the analysis. Women were more prevalent (77.4%) and peritoneal metastasis from ovarian origin accounted for 48.4%. Clavien II-V grades occurred in 30 (57.7%) patients. After prehabilitation, functional walking capacity improved by 42.2 m (39.62-44.72 m) compared with baseline data (p < 0.001), but no improvement was observed in the ASMI (p = 0.301). Patients able to walk at least 360 m after prehabilitation suffered fewer Clavien-Dindo II-V postoperative complications (p = 0.016). A T6MWT of less than 360 m was identified as an independent risk factor in the multivariable analysis (OR 3.99; 1.01-15.79 p = 0.048). CONCLUSIONS: This home-based trimodal prehabilitation program improved functional walking capacity but not ASMI scores in patients with peritoneal metastasis before surgery. A T6MWT of less than 360 m was found to be a risk factor for postoperative complications.
RESUMO
INTRODUCTION: Palliative care in neurodegenerative diseases is useful but underused. The objective of this study is to know how palliative care (PC) is applied in Spain in order to identify limitations and unmet needs. MATERIALS AND METHODS: It is a descriptive, observational, cross-sectional study, anonymous survey type of 20 questions, directed and answered by neurologists dedicated to movement disorders (MD) in Spain. RESULTS: 58 responses were obtained from neurologists from 15 autonomous communities. 69% answered that they did not have a specialised MD nursing facility but did have a PC team in their centre (81%). No specific protocol for PC in MD was identified. All except one neurologist stated that they lacked sufficient training in PC, the main training need being the "advance directives explanation". Only 1 in 4 neurologists answered routinely explaining advance healthcare planning to their patients, recognising up to 84.5% of neurologists not knowing how to assess the patient's competence. 60.3% of those surveyed answered that between 10% and 30% of their patients would be candidates for PC, although 1 in 3 said they were not clear when to refer the patient to PC. 100% of neurologists affirmed the priority need to implement PC protocols in MD. CONCLUSIONS: Our study shows a formative deficit in PC in this area and in the care of the patient with movement disorders and their environment, and should serve as a starting point to develop consensual care protocols.
RESUMO
PURPOSE: To evaluate the reproducibility in the measurement of ocular biometric parameters using a new swept-source optical coherence tomographer and its comparability with an optical low coherence reflectometry biometer. DESIGN: An observational, descriptive, cross-sectional study. METHODS: 45 right eyes of 45 patients diagnosed with cataract were included. Three successive biometric measurements with Anterion and one with Lenstar LS900 were performed on each patient. The following variables were collected: axial length (AXL), anterior chamber depth (ACD), flat K (K1), steep K (K2), central corneal thickness (CCT), lens thickness (LT) and white-to-white distance (WTW). The intrasubject standard deviation (Sw) and the coefficient of Pearson "R" were calculated in order to assess the repeatability. The intraclass correlation coefficient (ICC) and the concordance correlation coefficient (CCC) were obtained to evaluate the comparability between devices. A Bland-Altman plot was performed for each variable. RESULTS: The coefficient of Pearson was excellent and statistically significant in the evaluation of the repeatability in all the variables. The highest values were 0.987 (AXL), 0.983 (CCT) and 0.942 (ACD). There were no statically significant differences between repeated measurements with Anterion in all the parameters. The ICC and CCC were excellent in the evaluation of AXL, CCT and ACD, and were also good in regard to K1, K2, LT and WTW. CONCLUSIONS: Performing biometry with the SS-OCT Anterion is a reliable and reproducible procedure, and it is comparable with the Lenstar LS900.

OBJECTIVE: To assess the effectiveness of colchicine, compared with standard of care, for reducing mortality, admission to intensive care, and use of mechanical ventilation. MATERIALS AND METHODS: We performed a systematic review, meta-analysis, and sequential trial analysis. The terms (SARS-CoV-2 OR COVID-19 OR coronavirus) AND (colchicine) were searched in MEDLINE, Scopus, Embase, Cochrane Central Register of Controlled Trials, and preprint repositories (February 2020 to April 2021, extended to June 2021). Risk of bias for randomised controlled trials and observational studies were assessed using the tools RoB 2.0 and ROBINS-I, respectively. We performed subgroup analyses based on study design and sensitivity analyses based on time of colchicine administration. RESULTS: We included six observational studies (1329 patients) and five clinical trials (16,048 patients). All studies but one were conducted in the hospital setting. Colchicine treatment was not associated with a significant decrease in mortality (RR 0.93, 95% CI 0.87 to 1; p=0.06, I2=72%) with a significant subgroup effect (p<0.001) depending on the design of the studies. The drug was effective in observational studies (RR 0.57, 95% CI 0.46 to 0.70, p<0.001, I2=50%) but not in clinical trials (RR 0.99, 95% CI 0.92 to 1.07, p=0.89, I2=21%). The effect of colchicine on intensive care admissions and the need for mechanical ventilation could not be confirmed. Trial sequential boundaries for cumulative meta-analyses of randomised controlled trials suggested no significant effect on mortality (p=0.182) beyond the optimal information size (13,107 patients). CONCLUSIONS: Our results suggest that colchicine treatment has no effect on mortality in hospitalised patients with SARS-CoV-2 infection, and that no further confirmatory clinical trials are needed owing to futility.
