Differential response to preoperative exercise training in patients candidates to cardiac valve replacement.

BACKGROUND: There is lack of evidence regarding safety, effectiveness and applicability of prehabilitation on cardiac surgery population, particularly in patients candidates to cardiac valve replacement. The aim of the study is to assess and compare the effect of a multimodal prehabilitation program on functional capacity in patients with severe aortic stenosis (AoS) and severe mitral regurgitation (MR) proposed for valve replacement surgery. METHODS: Secondary analysis from a randomised controlled trial whose main objective was to analyze the efficacy of a 4-6 weeks multimodal prehabilitation program in cardiac surgery on reducing postoperative complications. For this secondary analysis, only candidates for valve replacement surgery were selected. The primary outcome was the change in endurance time (ET) from baseline to preoperative assessment measured by a cycling constant work-rate cardiopulmonary exercise test. RESULTS: 68 patients were included in this secondary analysis, 34 (20 AoS and 14 MR) were allocated to the prehabilitation group and 34 (20 AoS and 14 MR) to control group. At baseline, patients with AoS had better left systolic ventricular function and lower prevalence of atrial fibrillation compared to MR (p = 0.022 and p = 0.035 respectively). After prehabilitation program, patients with MR showed greater improvement in ET than AoS patients (101% vs. 66% increase from baseline). No adverse events related to the prehabilitation program were observed. CONCLUSIONS: A 4-6 week exercise training program is safe and overall improves functional capacity in patients with severe AoS and MR. However, exercise response is different according to the cardiac valve type disfunction, and further studies are needed to know the factors that predispose some patients to have better training response. TRIAL REGISTRATION: The study has been registered on the Registry of National Institutes of Health ClinicalTrials.gov (NCT03466606) (05/03/2018).

Multimodal Prehabilitation in Heart Transplant Recipients Improves Short-Term Post-Transplant Outcomes without Increasing Costs.

(1) Background and aim: This study aimed to investigate the impact of prehabilitation on the postoperative outcomes of heart transplantation and its cost-effectiveness. (2) Methods: This single-center, ambispective cohort study included forty-six candidates for elective heart transplantation from 2017 to 2021 attending a multimodal prehabilitation program consisting of supervised exercise training, physical activity promotion, nutritional optimization, and psychological support. The postoperative course was compared to a control cohort consisting of patients transplanted from 2014 to 2017 and those contemporaneously not involved in prehabilitation. (3) Results: A significant improvement was observed in preoperative functional capacity (endurance time 281 vs. 728 s, p < 0.001) and quality-of-life (Minnesota score 58 vs. 47, p = 0.046) after the program. No exercise-related events were registered. The prehabilitation cohort showed a lower rate and severity of postoperative complications (comprehensive complication index 37 vs. 31, p = 0.033), lower mechanical ventilation time (37 vs. 20 h, p = 0.032), ICU stay (7 vs. 5 days, p = 0.01), total hospitalization stay (23 vs. 18 days, p = 0.008) and less need for transfer to nursing/rehabilitation facilities after hospital discharge (31% vs. 3%, p = 0.009). A cost-consequence analysis showed that prehabilitation did not increase the total surgical process costs. (4) Conclusions: Multimodal prehabilitation before heart transplantation has benefits on short-term postoperative outcomes potentially attributable to enhancement of physical status, without cost-increasing.

Feasibility of a Multimodal Prehabilitation Programme in Patients Undergoing Cytoreductive Surgery for Advanced Ovarian Cancer: A Pilot Study.

INTRODUCTION: Treatment for advanced ovarian cancer (AOC) comprises cytoreductive surgery combined with chemotherapy. Multimodal prehabilitation programmes before surgery have demonstrated efficacy in postoperative outcomes in non-gynaecological surgeries. However, the viability and effects of these programmes on patients with AOC are unknown. We aimed to evaluate the feasibility and postoperative impact of a multimodal prehabilitation programme in AOC patients undergoing surgery. METHODS: This single-centre, before-and-after intervention pilot study included 34 patients in two cohorts: the prehabilitation cohort prospectively included 15 patients receiving supervised exercise, nutritional optimisation, and psychological preparation from December 2019 to January 2021; the control cohort included 19 consecutive patients between January 2018 and November 2019. Enhanced Recovery After Surgery guidelines were followed. RESULTS: The overall adherence to the multimodal prehabilitation programme was 80%, with 86.7% adherence to exercise training, 100% adherence to nutritional optimisation, and 80% adherence to psychological preparation. The median hospital stay was shorter in the prehabilitation cohort (5 (IQR, 4-6) vs. 7 days (IQR, 5-9) in the control cohort, p = 0.04). Differences in postoperative complications using the comprehensive complication index (CCI) were not significant (CCI score: 9.3 (SD 12.12) in the prehabilitation cohort vs. 16.61 (SD 16.89) in the control cohort, p = 0.08). The median time to starting chemotherapy was shorter in the prehabilitation cohort (25 (IQR, 23-25) vs. 35 days (IQR, 28-45) in the control cohort, p = 0.03). CONCLUSIONS: A multimodal prehabilitation programme before cytoreductive surgery is feasible in AOC patients with no major adverse effects, and results in significantly shorter hospital stays and time to starting chemotherapy.

Which Are the Main Factors Influencing Corporate Social Responsibility Information Disclosures on Universities' Websites.

Universities are now becoming more active in the field of Corporate Social Responsibility (CSR). Nevertheless, they do not appear to be granting the same degree of importance to the dissemination of these activities. This article analyses the voluntary corporate social responsibility information disclosed by leading USA universities. We created several indexes of corporate social responsibility information disclosure and examined main universities' characteristics that affect corporate social responsibility disclosure by these entities. The findings obtained show that the universities are strongly committed to the dissemination of corporate social responsibility information, and that a university's size, affiliation, public/private status and ranking position are the factors most significantly affecting its online disclosure of general corporate social responsibility information. These findings could be useful for university administrators, especially those in public universities, highlighting the importance of developing and supporting policies and incentives to promote CSR disclosure and thus attract new students and meet social expectations about the ethical behaviour of universities.

Expanding the actions of Open Government in higher education sector: From web transparency to Open Science.

Universities have been pressured by governments to change their way of acting and to be more responsible with the requirements of social development to face the challenges of globalization. To this end, universities must use the principles of Open Science, to allow them to be more transparent regarding the dissemination of scientific results. The purpose of this paper is firstly, to determine the progress made in Open Access policies made by the best-ranked universities regarding ARWU. Secondly, to examine influencing factors that enhance the level of openness in researching, in particular, "transparency", "reputation", "participation", "funding", "foundation" and "size". The main results show that those private and older universities, best-ranked in terms of excellence researching and those that have been gradually adopting Open Government policies concerning the dissemination of information through institutional web pages and social participation, are the most interested with complying the recommendations established by the authorities of the Open Science projects.

Multimodal prehabilitation as strategy for reduction of postoperative complications after cardiac surgery: a randomised controlled trial protocol.

INTRODUCTION: Prehabilitation programmes that combine exercise training, nutritional support and emotional reinforcement (multimodal prehabilitation) have demonstrated efficacy reducing postoperative complications in the context of abdominal surgery. However, such programmes have seldom been studied in cardiac surgery, one of the surgeries associated with higher postoperative morbidity and mortality. This trial will assess the feasibility and efficacy in terms of reduction of postoperative complications and cost-effectiveness of a multimodal prehabilitation programme comparing to the standard of care in cardiac surgical patients. METHODS AND ANALYSIS: This is a single-centre, randomised, open-label, controlled trial with a 1:1 ratio. Consecutive 160 elective valve replacement and/or coronary revascularisation surgical patients will be randomised to either standard of care or 4-6 weeks of multimodal prehabilitation that will consist in (1) two times/week supervised endurance and strength exercise training sessions, (2) promotion of physical activity and healthy lifestyle, (3) respiratory physiotherapy, (4) nutrition counselling and supplementation if needed, and (5) weekly mindfulness sessions. Baseline, preoperative and 3-month postoperative data will be collected by an independent blinded evaluator. The primary outcome of this study will be the incidence of postoperative complications. ETHICS AND DISSEMINATION: This study has been approved by the Ethics Committee of Clinical investigation of Hospital Clinic de Barcelona (HCB/2017/0708). The results will be disseminated in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT03466606.

Alternative management structures for municipal waste collection services: the influence of economic and political factors.

Identifying and characterising the factors that determine why a local authority opts for a particular way of managing its waste collection service is an important issue, warranting research interest in the field of municipal solid waste (MSW) management. This paper presents empirical evidence spanning a broad time horizon (2002-2010) showing that economic and political factors impact in different ways on the provision of waste management services. We examine five alternatives in this area, including public and private service delivery formulas and, within each field, individual and joint options. Our findings highlight the importance of the service cost and that of the various indicators of fiscal stress as determinant factors of management decisions regarding the provision of MSW management services.
