Association of Abdominal Circumference, Body Mass Index, and Inflammation in Kidney Transplant Recipients

Increased abdominal circumference is a marker of obesity, and it is associated with increased mortality in renal transplant recipients. Recent findings suggest that increased visceral fat deposition is a modifier of inflammation. However, little is known about the association of inflammation with abdominal circumference in kidney transplant recipients.

We examined human lung tissue from COPD patients and normal control subjects, and found a substantial increase in p16-expressing alveolar cells in COPD patients. Using a transgenic mouse deficient for p16, we demonstrated that lungs of mice lacking p16 were structurally and functionally resistant to CS-induced emphysema due to activation of IGF1/Akt regenerative and protective signaling.

The scarcity of organs available for transplantation has increased attempts to augment transplantation by utilizing obese living kidney donors. The literature has suggested that these donors have increased risks postdonation. Not surprising, the threshold for living kidney donor approval among obese persons is typically higher and the process more costly. Therefore, a screening tool to predict the likelihood of approval among obese living kidney donor candidates was created.

Authors: Li JS, Li B Abstract Renal failure is one of the most important causes of mortality and morbidity all over the world. Acute kidney injury (AKI) is a major clinical problem that affects up to 5% of all hospitalized patients. Although the kidney has a remarkable capacity for regeneration after acute injury, the mortality among patients with severe AKI remains dismally high, and in clinical practice, most patients cannot be cured completely and suffer from chronic kidney disease (CKD). Recently, the incidence and prevalence of CKD have increased, largely as a result of the enhanced prevalence of diabetes and ...

We examined 9293 individuals from the Copenhagen General Population Study using nuclear magnetic resonance spectroscopy measurements of total cholesterol, free- and esterified cholesterol, triglycerides, phospholipids, and particle concentration. Fourteen subclasses of decreasing size and their lipid constituents were analysed: six subclasses were very low-density lipoprotein (VLDL), one intermediate-density lipoprotein (IDL), three low-density lipoprotein (LDL), and four subclasses were high-density lipoprotein (HDL). Remnant lipoproteins were VLDL and IDL combined. Mean nonfasting cholesterol concentration was 72...

Abstract BACKGROUND: Direct-acting antivirals have changed the landscape of hepatitis C virus (HCV) care. While transplantation with HCV-positive donor organs is increasing, little is known about providers' attitudes toward this topic. The aim of this study is to determine providers' attitudes toward HCV-positive kidney transplantation. METHODS: Willing transplant and nontransplant nephrologists, transplant surgeons, and mid-level providers completed an online survey from April through May 2018. The survey asked about HCV knowledge and willingness to transplant HCV-positive antibody, nucleic acid testing-posi...

The rising prevalence of obesity is a well known global problem, as is the relationship between obesity and end stage renal disease (ESRD). Even though the best treatment for ESRD is kidney transplantation, haemodialysis, which depends on vascular access, is a key element in the management of ESRD. The first line haemodialysis option with the best short and long term results is the creation of native arteriovenous access (arteriovenous fistula, AVF). Unfortunately, obese patients with ESRD are higher risk of unsuccessful AVF creation due to maturation problems associated with deep veins.

ConclusionIn DT1 patients, renal transplantation is the best treatment for ESRD despite the use of corticosteroids and anticalcineurins. However, prior explorations of good cardiac function and adequate vascular compliance are essential to reduce the risk of CV.

ConclusionThe transplant population has multiple cardiovascular risk factors. Early detection and correction of these factors must be a priority in order to improve the survival of these patients.

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...
