Association between the 6MWT and other measurements of physical functioning in patients with cancer awaiting major surgery.

BACKGROUND: The Six Minute Walk Test (6MWT) is a widely used measure of functional capacity in (p)rehabilitation of cancer patients, but it is time-consuming and requires specific space conditions. In this study we explore the association between the 6MWT with other measurements of physical functioning and their predictive value in classifying patients according to their estimated functional capacity. DESIGN: This prospective study included cancer patients referred to a prehabilitation programme prior to major surgery. For each patient, data on different measurements of physical functioning including the Duke Activity Status Index (DASI), the handgrip strength, the 30" Sit-to-Stand Test and self-reported physical activity levels were collected. Bivariate associations were performed to determine the association between the 6MWT and other variables. Multivariate analyses were performed to identify potential predictive factors of 6MWT in this population. A subsequent algorithm was developed to classify patients based on their functional capacity (good performance - 6MWT>400 m or poor performance 6MWT<400 m) RESULTS: Between mid-2018 to mid 2022, 692 patients were assessed of whom the 6MWT was performed in 524 (75.7 %) (mean age 72.5 ± 11.8 years; 57.1 % men). Moderate-to-strong correlations were found between 6MWT and 30" Sit-To-Stand Test (r = 0.54, p < 0.001), DASI (r = 0.68; p < 0.001) and handgrip strength (r = 0.5; p < 0.001). Multivariate analyses confirmed that a combination of six variables were able to classify 80 % of patients in good (>400 m) or poor (<400 m) performance in the 6MWT. CONCLUSION: The 6MWT was moderately associated with several variables of physical functioning, a combination of which can be used to predict performance in the 6MWT.

Challenges in perioperative blood transfusions in kidney transplantation and the need for Patient Blood Management.

BACKGROUND: Anemia is highly prevalent in end-stage chronic kidney disease patients, increasing their risk of receiving blood transfusions during and on the days after a kidney transplant (KTx) surgery. However, there is currently a lack of data that thoroughly describes this phenomenon in this population, the associated risk factors, and how they could benefit from the application of Patient Blood Management (PBM) guidelines. MATERIALS AND METHODS: Observational study. All adult patients who received a KTx between January 1st, 2020, and December 31st, 2021, were included and followed up to six months after transplantation. Those who received a multiorgan transplant, whose data was missing in the electronic health records, and who had primary non-function were excluded. We recorded donor and recipient characteristics, cold ischemia time, preoperative hemoglobin concentration, iron status deficiency biomarkers, incidence of delayed graft function and biopsy-proven graft rejections, and graft function at discharge and 6 months after transplantation. RESULTS: We found that a high amount (39%) of KTx recipients required at least one blood transfusion during the perioperative period. And that 1) most of these patients had anemia at the time of transplantation (85.4%), 2) iron status upon admission was associated with the transfusion of more blood units (3.9 vs 2.7, p=0.019), 3) surgical reintervention (OR 7.28, 2.35-22.54) and deceased donor donation (OR 1.99, 1.24-3.21) were associated with an increased risk of transfusion, and finally, 4) there was an association between a higher number of blood units transfused and impaired kidney graft function six months after hospital discharge (1.6 vs 1.9, p=0.02). CONCLUSIONS: In conclusion, PBM guidelines should be applied to patients on the KTx deceased donor waiting list and especially those scheduled to receive a transplant from a living donor. This could potentially increase the utilization efficiency of blood products and avoid transfusion-related severe adverse effects.

Resumen Este artículo tiene como objetivo presentar el programa "Everybody has a body" para la prevención de trastornos de la conducta alimentaria (TCA) y obesidad en población preadolescente, que se ha impartido en varias escuelas de España durante el año 2021, contando con una muestra compuesta por 179 preadolescentes de entre 10 y 12 años. Este programa, elaborado por las investigadoras, tiene un carácter innovador, puesto que integra la prevención de los TCA y la obesidad, desde un enfoque que fomenta un estilo de vida saludable, a través del desarrollo de una conciencia crítica con los cánones de belleza, fortalecimiento de la autoestima e imagen corporal, entre otros. El impacto del programa ha sido positivo, y los participantes han mejorado en todas las dimensiones evaluadas. Los resultados obtenidos manifiestan, sin lugar a dudas, la necesidad de educar en salud en las escuelas. Se postula como una exigencia para cualquier sistema educativo, más allá de las fronteras nacionales, puesto que los TCA y la obesidad se han convertido en un problema global, que afecta a gran parte del planeta, minando la salud y calidad de vida de las personas, generando grandes costes económicos a los gobiernos y aumentando las desigualdades sociales.

Abstract This article presents the program entitled "Everybody has a body" for the prevention of eating behavior disorders (ED) and obesity in the preadolescent population. It was taught in several schools in Spain during the year 2021, with a sample composed of 179 tweens between 10 and 12 years old. This program, developed by the researchers, is innovative since it integrates the prevention of eating disorders and obesity, from an approach that promotes a healthy lifestyle, through the development of a critical awareness of the canons of beauty, strengthening self-esteem and body image, among others. The impact of the program has been positive, and the participants have improved in all the dimensions evaluated. The results obtained show, without a doubt, the need for health education in schools. It is postulated as a requirement for any educational system, beyond national borders, since eating disorders and obesity have become a global problem that affects a large part of the planet, undermining people's health and quality of life, generating large economic costs for governments and increasing social inequalities.

Perioperative Management for the First Uterine Transplant in Southern Europe: A Case Report.

BACKGROUND: The aim of this study was to describe perioperative management concerning the living donor uterine transplantation program at the Hospital Clinic (Barcelona, Spain), in the first successful procedure in Southern Europe. METHODS: Before the date of surgery, both the donor and the recipient are evaluated in the outpatient clinic to detect any possible comorbidities that might complicate or altogether disallow the procedure. In the donor, with a robotically performed surgery, complications regarding cerebral and upper airway edema, as well as reduced access to the patient once docking occurs, are of utmost importance. An aggressive antithrombotic regimen must be in place that includes heparin administered both to the donor and the recipient and aspirin to the recipient. Different strategies to reduce ischemia-reperfusion injury have been studied, with reduced ischemia times currently being the most effective. RESULTS: After surgery, both donor and recipient were taken to the intensive care unit overnight, transferred to the conventional ward the following day and discharged from the hospital within the week. The recipient had her first menstrual period 47 days after the surgery. CONCLUSIONS: The description of challenges regarding perioperative care of women who undergo uterine transplant programs and the rationale in anesthetic management may help other teams implant this program as a solution for a disease that profoundly impairs quality of life.

Perioperative Nursing as the Guiding Thread of a Prehabilitation Program.

Multimodal preoperative prehabilitation has been shown to be effective in improving the functional capacity of cancer patients, reducing postoperative complications and the length of hospital and ICU stay after surgery. The availability of prehabilitation units that gather all the professionals involved in patient care facilitates the development of integrated and patient-centered multimodal prehabilitation programs, as well as patient adherence. This article describes the process of creating a prehabilitation unit in our center and the role of perioperative nursing. Initially, the project was launched with the performance of a research study on prehabilitation for gastrointestinal cancer surgery. The results of this study encouraged us to continue the implementation of the unit. Progressively, multimodal prehabilitation programs focusing on each type of patient and surgery were developed. Currently, our prehabilitation unit is a care unit that has its own gym, which allows supervised training of cancer patients prior to surgery. Likewise, the evolution of perioperative nursing in the unit is described: from collaboration and assistance in the integral evaluation of the patient at the beginning to current work as a case manager; a task that has proven extremely important for the comprehensive and continuous care of the patient.

Outcomes after 20 years of experience in minimally invasive living-donor nephrectomy.

INTRODUCTION: The transperitoneal laparoscopic approach is considered the gold standard technique for living kidney donation. Other accepted laparoscopic techniques include the retroperitoneal approach, natural orifice transluminal endoscopic surgery (NOTES)-assisted, laparo-endoscopic single-site surgery (LESS), with excellent results in the donor and graft. Many studies have compared these techniques with open ones. Our objective is to describe our experience and results in minimally invasive living-donor nephrectomies (MILDN): laparoscopic, NOTES-assisted, and LESS since their introduction in March 2002. MATERIALS AND METHODS: We conducted a retrospective observational study of donors undergoing MILDN between March 2002 and March 2020. RESULTS: A total of 714 MILDNs were performed at our centre. All were completed, except for one, because of recipient death. The conventional laparoscopic approach was used in 541 cases (75.88%), NOTES in 116 (16.9%), LESS in 55 (7.7%), and one mini open (0.14%). Two-thirds of the donors were females (478 cases). The mean donor age was 52.87 years (SD 10.93). Six donors (0.8%) were diagnosed beforehand with a small renal mass, which was removed before transplantation in bench surgery. The right kidney was removed in 17.8% of cases. Warm ischaemia time was higher in the NOTES and LESS groups. We had eight conversions. The global intraoperative and postoperative complication rates were 6.8% and 4.9%, respectively. None of the donors developed renal disease during follow-up (mean 3.68 years). Five-year recipient and graft survival rates were 98.8% and 96.8%, respectively. CONCLUSIONS: MILDN techniques are safe for donors and grafts, with low complication.

Perioperative considerations for kidney and pancreas-kidney transplantation.

Kidney transplantation is the treatment of choice in patients with end-stage renal disease, as it improves survival and quality of life. Living donor kidney transplant prior to pancreas transplantation, or simultaneous pancreas and kidney transplantation are discussed. Patients usually present comorbidities and extensive preoperative workups are recommended, especially cardiac assessment, though type and frequency of surveillance is not established. Nephroprotective strategies include adequate fluid status and goal-directed therapy. The conventional use of diuretics has not demonstrated a real nephroprotective effect at follow-up. Thromboprophylaxis regimes, especially for the pancreatic graft outcome, are of importance. Notably, transplantation in the obese population has increased in recent decades. Strict preoperative evaluation and pulmonary considerations must be kept in mind. Finally, robotic kidney transplant is a recent approach that presents anesthetic challenges, mainly related to steep Trendelenburg position and fluid restriction.

International multicenter observational study on assessment of ventilatory management during general anaesthesia for robotic surgery and its effects on postoperative pulmonary complication (AVATaR): study protocol and statistical analysis plan.

INTRODUCTION: Robotic-assisted surgery (RAS) has emerged as an alternative minimally invasive surgical option. Despite its growing applicability, the frequent need for pneumoperitoneum and Trendelenburg position could significantly affect respiratory mechanics during RAS. AVATaR is an international multicenter observational study aiming to assess the incidence of postoperative pulmonary complications (PPC), to characterise current practices of mechanical ventilation (MV) and to evaluate a possible association between ventilatory parameters and PPC in patients undergoing RAS. METHODS AND ANALYSIS: AVATaR is an observational study of surgical patients undergoing MV for general anaesthesia for RAS. The primary outcome is the incidence of PPC during the first five postoperative days. Secondary outcomes include practice of MV, effect of surgical positioning on MV, effect of MV on clinical outcome and intraoperative complications. ETHICS AND DISSEMINATION: This study was approved by the Institutional Review Board of the Hospital Israelita Albert Einstein. The study results will be published in peer-reviewed journals and disseminated at international conferences. TRIAL REGISTRATION NUMBER: NCT02989415; Pre-results.

Reproducibility of Electronic Von Frey and Von Frey monofilaments testing.

OBJECTIVES: Von Frey monofilaments (VFM) and Electronic von Frey are used as quantitative sensory testing to explore mechanical hyperalgesia. The aim of the study was to determine VFM and Electronic von Frey reproducibility and the time required for testing undamaged areas in volunteers and surgical in-hospital patients. METHODS: Prospective study in 2 groups of individuals without neurological disorders and not receiving treatments that alter sensorial response. Group 1 was formed by 30 healthy volunteers and group 2 by 28 patients after knee arthroplasty who received unilateral femoral block as postoperative analgesia. Testing was performed by 2 trained investigators in the forearm and abdominal wall and repeated 24 hours later. Pain threshold was determined as the VMF or the pressure rate applied with the Electronic von Frey referred to as unpleasant. The time used in each test was measured. Intraobserver and interobserver reproducibility were analyzed by means of Kappa and Lin coefficients. RESULTS: Intraobserver and interobserver reproducibility for VFM was only fair or moderate in both groups (Kappa<0.6). Intraobserver reproducibility for Electronic von Frey was good in Group 1 (Lin 0.61 to 0.8) and almost perfect in Group 2 (Lin>0.8). No differences were found between the 2 tested areas. Time used was 6.03 and 3.16 minutes for VFM and Electronic von Frey, respectively. DISCUSSION: Exploration of mechanical allodynia in postoperative patients requires rapid and reliable quantitative sensory testing. Electronic von Frey was more reliable and rapid than VFM in exploring mechanical pain thresholds in undamaged areas in volunteers and patients. Further studies are required to confirm whether these results can be extrapolated to areas affected by surgery.
