Background Hallux valgus is bilateral in up to 84 % of cases. In the setting of simultaneous bilateral correction, we aim to evaluate if minimally invasive percutaneous surgery (MIS) provides any advantage compared to conventional open surgery. Methods 52 feet (26 patients) undergoing simultaneous bilateral MIS surgery were matched by severity of deformity to 52 feet (26 patients) undergoing simultaneous conventional open surgery. Patients were followed for a minimum of six months. Pre- and post-operative radiographs and clinical records were reviewed. Results There were no significant differences in pre-operative function or pain between both groups. Post-operatively, the mean hallux valgus angle (HVA) was significantly lower in the MIS group. (HVA MIS – 8.6; Open – 11.8, P = 0.013). There were no significant differences in post-operative outcome and patient satisfaction between both groups. Conclusion This study demonstrates that simultaneous bilateral MIS hallux valgus surgery can be considered for patients with bilateral symptomatic hallux valgus.Background The number of liver transplantations is increasing worldwide, and Brazil ranks in the second position. It has one of the biggest public health care systems, which is responsible for the coordination and financial funding of transplantation procedures. Meeting the demands of such a large system of transplantation has become a challenge, particularly when attempting to minimize costs of scarce and expensive resources. The aim of this study was to investigate the process of donation, the retrieval of organs, and the transplantation itself using engineering methods based on logistics analyses. Methods Three steps were used study planning, data gathering, and data analysis. Researchers surveyed professionals to acquire raw information based on their observations, experience, and knowledge. Then, a data analysis was conducted, putting together all the information gathered during the previous steps. Bias was removed, and conflicting perceptions were resolved in order to have a standard view on the transplantation process. Results Data was gathered between 2014 and 2018 and included 5502 liver donors and 2678 (48.7%) patients who received liver transplants organs. A total of 2824 organs were refused because of logistics issues (transport and handling). Interviews of health care professionals enabled the design of a process map in which 4 stakeholders were identified patient, physician, organ, and information. Conclusions The liver transplantation process is analyzed based on a supply chain methodology applying this knowledge and putting together medical and engineering sciences to promote better efficiency and outcomes for the transplantation program. Future studies should focus on the implementation of these ideas aiming to promote optimization gains in any step of the process.Objective The objective of this study was to analyze the effects of obesity on postoperative complications and patient and graft survival after kidney transplantation. GW501516 Methods We retrospectively included 506 patients who received a kidney transplant in our center during eleven years. Obesity was defined by a body mass index ≥ 30 kg/m2 based on World Health Organization criteria. Using univariate and multivariate analyses, we evaluated the impact of obesity on surgical complications according to the Clavien-Dindo classification up to 30 days after surgery. The impact of obesity on graft and patient survival was assessed using a Cox proportional regression model. Results Seventy-one patients were obese (14%), and mean follow-up was 63.1 months (59.7-66.5). By multivariable analysis, obesity was associated with delayed graft function (hazard ratio = 2.60 , P = .004). Obesity was not associated with surgical complications, but cardiovascular history was (HR = 1.68 , P = .048). By Cox regression analysis, obesity was significantly associated with a higher risk of graft loss (HR = 1.55 , P = .042) but not with patient survival (HR = 1.82 , P = .106). Conclusion Obesity was associated with delayed graft function and graft loss. However, it was not associated with surgical complications. Kidney transplantation remains the best therapy for obese patients suffering from end-stage renal disease, despite shorter graft survival.Background Respiratory complications of solid organ transplant (SOT) are a diagnostic and therapeutic challenge when requiring intensive care unit (ICU) admission. We aimed at describing this challenge in a prospective cohort of SOT recipients admitted in the ICU. Methods In this post hoc analysis of an international cohort of immunocompromised patients admitted in the ICU for an acute respiratory failure, we analyzed all SOT recipients and compared their severity, etiologic diagnosis, prognosis, and outcome according to the performance of an invasive diagnostic strategy (encompassing a fiber-optic bronchoscopy and bronchoalveolar lavage), the type of transplanted organ, and the need of invasive ventilation at day 1. Results Among 1611 patients included in the primary study, 142 were SOT recipients (kidney, n = 73; 51.4%; lung, n = 33; 23.2%; liver, n = 29; 20.4%; heart, n = 7; 4.9%). Lung transplant recipients were younger than other SOT recipients, and severity did not differ across type of received organ. An invasive diagnostic strategy was more frequently performed in lung transplant recipients with a trend toward a higher rate of bacterial etiology in lung than kidney transplant recipients. Overall ICU survival of SOT recipients was 75.4%. Invasive diagnostic strategy, type of transplanted organ, and need of invasive mechanical ventilation at day 1 did not affect ICU prognosis. Conclusions ICU management of hypoxemic acute respiratory failure in SOT recipients translated into a low ICU mortality rate, whatever the transplanted organ or the acute respiratory failure cause. The post-ICU burden of acute respiratory failure SOT recipients remains to be investigated.Poland’s Central Unrelated Potential Bone Marrow Donor and Cord Blood Registry (CBMDR Poltransplant) was established in 2011. Affiliated with the World Marrow Donor Association (WMDA) as PL5, the CBMDR is an internationally recognized hematopoietic stem cell donor registry with a large, high-quality donor database. Overall, Polish resources in this domain are the second largest in Europe and the fourth largest in the world, accounting for 4.8% of the WMDA Register of over 33.5 million records. In the last 10 years, the number of potential hematopoietic stem cell donors registered in Poland has increased more than 10-fold, from about 146,000 to 1,579,809 at the end of 2018. Such a growing number of donors in the CBMDR is contributing to an increase in overall numbers of donor searches in Polish databases, as well as in donations from Polish donors.
