Commentary: Peri-Transplant Bariatric Surgery

ConclusionsAlthough bariatric surgery in the transplant population is not yet extensively studied and is mostly reported in small series, it seems a useful approach for the treatment of morbid obesity in these high-risk patients. Comparative data regarding optimal timing and type of bariatric procedure and long-term results are warranted.

In conclusion, we show here that sEVs are responsible for mediating paracrine senescence and speculate that they could be involved in inducing bystander senescence during therapy-induced senescence or aging. In fact, when compared to soluble factors, sEVs have different biophysical and biochemical properties as they have a longer lifespan than do soluble factors and they are more resistant to protease degradation. The idea that blocking sEV secretion could be a potential therapeutic approach to alleviate senescence "spreading" during chemotherapy-induced senescence or in aging tissues presents itself as a very at...

Purpose of review The safety of living donor nephrectomy is essential to the continued success, growth, and sustainability of the clinical practice of living donor kidney transplantation. This review summarizes recent advances in our understanding of the perioperative and long-term risks faced by living kidney donors. Recent findings Although adverse perioperative complications are extremely rare, donors particularly men, Black, or obese, frequently experience minor complications that result in delayed return to normal duties at home and work. Similarly, although long-term complications such as end-stage renal disease...

In this study, we determine whether transient reintroduction of embryonic stem cell cycle miR-294 promotes cardiomyocyte cell cycle reentry enhancing cardiac repair after myocardial injury. A doxycycline-inducible AAV9-miR-294 vector was delivered to mice for activating miR-294 in myocytes for 14 days continuously after myocardial infarction. miR-294-treated mice significantly improved left ventricular functions together with decreased infarct size and apoptosis 8 weeks after MI. Myocyte cell cycle reentry increased in miR-294 hearts parallel to increased small myocyte number in the heart. Isolated adult myocytes from miR-...

Background. Living kidney donors in the United States who were obese at donation are at increased risk of end-stage renal disease and may benefit from intensive postdonation follow-up. However, they are less likely to have complete follow-up data. Center variation and risk factors for incomplete follow-up are unknown. Methods. Adult living kidney donors with obesity (body mass index, ≥30 kg/m2) at donation reported to the Scientific Registry of Transplant Recipients from January 2005 to July 2015 were included (n = 13 831). Donor characteristics were compared by recorded serum creatinine at 6 months p...

ConclusionsWe could not find a relationship between serum fetuin-A levels and valvular calcification in kidney recipients. In this population, further studies are needed to assess the role of serum fetuin-A in valvular calcification.

In this study, analysis of antioxidant defense was performed on the blood samples from 184 "aged" individuals aged 65-90+ years, and compared to the blood samples of 37 individuals just about at the beginning of aging, aged 55-59 years. Statistically significant decreases of Zn,Cu-superoxide dismutase (SOD-1), catalase (CAT), and glutathione peroxidase (GSH-Px) activities were observed in elderly people in comparison with the control group. Moreover, an inverse correlation between the activities of SOD-1, CAT, and GSH-Px and the age of the examined persons was found. No age-related changes in glutathione reductas...

Authors: Chen G, Gao L, Li X Abstract BACKGROUND: Whether exercise can improve cardiovascular health in kidney transplant recipients (KTRs) is unclear. Therefore, we performed a systematic review of the effects of exercise on cardiovascular risk factors in this population setting. METHODS: Randomized control trials (RCTs) evaluating the impact of exercise on major clinical outcomes in KTRs were identified by searches in Cochrane CENTRAL, PubMed, EMBASE, OVID and CBM updated to December 2018. The main outcomes of interest were blood pressure, lipid profile, blood glucose level, arterial stiffness, kidney functio...

Context: The increasing need for kidney grafts has led to a progressive expansion in the selection criteria for deceased and living donors (LDs). While concerns regarding the use of organs from suboptimal deceased donors relate to the quality of the graft, donation from “marginal” LDs may pose potential harm to the donor.Subject of Review: Living kidney donation is a safe procedure, but is associated with a small risk of end-stage kidney disease in the long- term. When elderly subjects and those with comorbidities are considered, long-term post-donation data are missing, making decisions regarding donation from...

Abstract Obesity is a recognized worldwide epidemic with increasing prevalence in developing nations. Studies have shown that obesity is an independent risk factor for the development of chronic kidney disease (CKD) besides its link with diabetes mellitus and hypertension. We evaluated the renal status of obese patients using both the established [creatinine (Cr)] and new (cystatin C) markers of renal function. This was a cross-sectional study. Fifty-nine consenting adults attending the clinic for routine medical checks were recruited for this study. They were divided into obese and non-obese based on their body m...

Conclusions: While there is a certain overlap between the results of the current study and published transcriptomic profiles of non-transplanted livers with steatosis, we have identified discrete characteristics of the non-alcoholic fatty liver disease in liver grafts potentially utilizable for the establishment of predictive signature. Introduction Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in industrialized countries, its prevalence being estimated at 19–31.3% (1). It encompasses a range of conditions that are thought to arise from fatty liver (simple steatosis) throu...
