PURPOSE OF REVIEW: A growing number of pediatric acute lymphoblastic leukemia (ALL) and hematopoietic stem cell transplantation (HSCT) survivors reach adulthood and face long-term health-related problems. We review risk factors and the prevalence of the metabolic syndrome (MetS), a cluster of obesity-related comorbidities, including abdominal obesity, atherogenic dyslipidemia, elevated blood pressure, impaired glucose metabolism, and type 2 diabetes in ALL and HSCT survivors. RECENT FINDINGS: Components of the MetS are already detected during the first year of ALL maintenance therapy and significantly worsen over time...

Background: Observational data suggest that the fixed initial recommended tacrolimus (Tc) dosing (0.2 mg/kg/day) results in supratherapeutic drug levels in some patients during the early posttransplant period. The aim of the study was to analyze a wide panel of patient-related factors and their interactions which increase the risk for first Tc blood level > 15 ng/ml. Materials and Methods: We performed a retrospective analysis of 488 consecutive adult kidney transplant recipients who were initially treated with triple immunosuppressive regimen containing tacrolimus twice daily...

PURPOSE OF REVIEW: Obesity is a strong risk factor for the development of heart failure (HF). Diet, exercise, and weight-loss pharmacotherapies have limited potential to achieve significant and sustainable weight loss, especially in patients with symptomatic systolic HF. This review seeks to determine the role of bariatric surgery for patients with systolic HF and obesity. RECENT FINDINGS: Bariatric surgeries such as the laparoscopic sleeve gastrectomy (LSG) and Roux-en-Y gastric bypass (RYGB) represent the most successful long-term strategy for achieving weight loss and diabetes and hypertension remission in the general obese population...

BACKGROUND: Replacement therapy for hemophilia remains a lifelong treatment. Only gene therapy can cure hemophilia at a fundamental level. The clustered regularly interspaced short palindromic repeats-CRISPR associated nuclease 9 (CRISPR-Cas9) system is a versatile and convenient genome editing tool which can be applied to gene therapy for hemophilia. METHODS: A patient's induced pluripotent stem cells (iPSCs) were generated from their peripheral blood mononuclear cells (PBMNCs) using episomal vectors...

OBJECTIVES: Renal transplant is the criterion standard treatment for patients with end-stage renal disease. Because obesity rates are increasing in the global population, international standards on renal transplant in obese patients remain a gray area. The aim of this study was to determine whether renal transplant remains the treatment of choice in an obese patient with end-stage renal disease. MATERIALS AND METHODS: We performed a retrospective analysis on all patients who underwent renal transplant in our transplant unit between January 2008 and December 2013...

Hypothalamic obesity is often complicated in patients with craniopharyngioma due to hypothalamic damage by the tumor itself, treatment modalities, and associated multiple pituitary hormone deficiency. Hypothalamic obesity causes secondary diseases such as nonalcoholic fatty liver disease (NAFLD) and diabetes mellitus (DM). We report a 19-year-old female who was diagnosed with craniopharyngioma, developed hypothalamic obesity after tumor resection, and progressed to hepatopulmonary syndrome. She manifested NAFLD 1 year after tumor resection...

Human stem cell-based models of thermogenic adipocytes provide an opportunity for the establishment of new therapeutics, modeling of disease mechanisms, and understanding of development. Pluripotent stem cells, adipose-derived stem cells/preadipocytes, and programming-reprogramming-based approaches have been used to develop cell-based platforms for drug screening and transplantable therapeutics in the metabolic disease arena. Here we provide a detailed overview of these approaches, the latest advances in this field, and the opportunities and shortcomings they present...

Robotic-assisted kidney transplantation (RKT) with the Da Vinci (Intuitive, USA) platform has been recently developed to improve outcomes by decreasing surgical site complications and morbidity, especially in obese patients. This potential paradigm shift in the surgical technique of kidney transplantation is performed in only a few centers. For wider adoption of this high stake complex operation, we aimed to develop a procedure-specific simulation platform in a porcine model for the training of robotic intracorporeal vascular anastomosis and evaluating vascular anastomoses patency...

Post-kidney transplantation outcomes in obese patients remain uncertain. The aim of this study is to compare patient and graft survival and post-transplant complications in obese patients and non-obese patients. We performed a retrospective analysis of a sample of 245kidney transplantations performed between 2008 and 2014 in Clermont-Ferrand. Obese patients and non-obese patients have been compared. Then we compared obese patients who have lost at least 5% of their weight (OPP) with obese patients who did not lose weight (OPS), and non-obese patients who have lost at least 5% of their weight (NOPP) with non-obese patients who did not lose weight (NOPS)...

Introduction: Despite the feasibility and safety of bariatric procedures nowadays, high-risk patients with vast obesity and severe comorbidities demonstrate relatively high perioperative morbidity and mortality rates and, therefore, form a distinguished challenge for the bariatric surgeons. Methods: We retrospectively analyzed high-risk patients, who underwent bariatric surgery in University Hospital Leipzig between May 2012 and December 2016. High-risk patients were defined when (Bergeat et al...

INTRODUCTION: End-stage renal disease patients' access to the renal transplant (RT) waiting list (WL) depends on general criteria and their specific application in the different treatment units. METHODS: Study in nonhospital hemodialysis centers (n = 9), dependent on an adult RT center. Cases included 228 patients considered to have nonactive status on the WL due to incomplete immunologic data (no blood group or HLA typing) or temporary contraindication from an incomplete pretransplant study (nonimmunologic) or comorbidity...

BACKGROUND: Despite ventricular assist devices (VADs) becoming more common in heart failure (HF) treatment, it is still uncertain which patients are more prone to complications. One potential risk factor is increased body mass index (BMI), which is known to increase both all-cause mortality and mortality from ischemic heart disease; however, the role of the BMI in predicting morbidity and mortality following device implantation is unclear. METHODS: The study population for this single-institution retrospective chart review consisted of 136 patients with HF, who underwent VAD implantation between 2004 and 2015...

The feasibility of liver transplantation from old healthy donors suggests that this organ is able to preserve its functionality during aging. To explore the biological basis of this phenomenon, we characterized the epigenetic profile of liver biopsies collected from 45 healthy liver donors ranging from 13 to 90 years old using the Infinium HumanMethylation450 BeadChip. The analysis indicates that a large remodeling in DNA methylation patterns occurs, with 8823 age-associated differentially methylated CpG probes...

Partial hepatectomy is a versatile and reproducible method to study liver regeneration and the effect of cell based therapeutics in various pathological conditions. Partial hepatectomy also facilitates the increased engraftment and proliferation of transplanted cells by accelerating neovascularization and cell migration towards the liver. Here, we describe a simple protocol for performing 30% hepatectomy and transplantation of cells in the spleen of a non-obese diabetic/severe combined immunodeficient NOD.SCID (NOD...
