AI Article Synopsis

  • There is a global obesity pandemic, with around 30% of adults in Europe classified as obese, which is linked to a higher risk of chronic kidney disease (CKD) and related complications.
  • Although obesity generally increases mortality risk, data on how weight impacts survival in CKD patients is mixed, with some evidence suggesting better survival in obese end-stage renal disease (ESRD) patients.
  • Management strategies for obesity include lifestyle changes, bariatric surgery, and medication, with new treatments showing promise for non-CKD patients, but more research is needed specifically for those with CKD.

Article Abstract

There is a pandemic of obesity worldwide and in Europe up to 30% of the adult population is already obese. Obesity is strongly related to the risk of CKD, progression of CKD, and end-stage renal disease (ESRD), also after adjustment for age, sex, race, smoking status, comorbidities, and laboratory tests. In the general population, obesity increases the risk of death. In nondialysis-dependent CKD patients, the association between body mass index and weight with mortality is controversial. In ESRD patients, obesity is paradoxically associated with better survival. There are only a few studies investigating changes in weight in these patients and in most weight loss was associated with higher mortality. However, it is not clear if weight change was intentional or unintentional and this is an important limitation of these studies. Management of obesity includes life-style interventions, bariatric surgery, and pharmacotherapy. In the last 2 years, a long-acting glucagon-like peptide-1 (GLP-1) receptor agonist and GLP-1 and glucose-dependent insulinotropic polypeptide receptor agonist were shown to be effective in managing weight loss in non-CKD patients, but we are awaiting results of more definitive studies in CKD patients.

Aims: The sodium-glucose cotransporter 2 inhibitor canagliflozin reduces the risk of heart failure (HF) hospitalization or cardiovascular death and chronic kidney disease (CKD) progression among patients with type 2 diabetes at high cardiovascular risk or with CKD. Patients with type 2 diabetes commonly have coexisting HF or CKD that require treatment with loop diuretics; however, the prognostic implications of oral loop diuretic intensification are not well characterized.

Methods And Results: In this participant-level pooled analysis of the CREDENCE and CANVAS trials (not including CANVAS-R), 1454/8731 (16.

Chronic kidney disease (CKD) affects 10-15% globally and is a marked independent risk factor for cardiovascular disease. Prevalence estimations are essential for public health planning and implementation of CKD treatment strategies. This study aimed to estimate the prevalence and stages of CKD in the population-based Lolland-Falster Health Study, set in a rural provincial area with the lowest socioeconomic status in Denmark.

Background: It is clinically relevant to predict outcomes in dogs with acute kidney injury (AKI) treated with haemodialysis. The aim of this study was to evaluate the prognostic value of contrast-enhanced ultrasound (CEUS) and its role in discriminating between AKI and acute impairment associated with chronic kidney disease (AKI/CKD).

Methods: Dogs diagnosed with AKI or AKI/CKD were prospectively enrolled in the study.

Hemodialysis and bioartificial kidney (BAK), which mimic both physical and biological functions, can significantly impact chronic kidney disease (CKD) patients. Here we report on Hollow fiber membranes (HFMs) with enhanced separation of uremic toxins along with enhanced hemocompatibility and biocompatibility that also promote the growth of kidney cells. The improvement arises from the addition of titanium dioxide (0.

Background: The use of telemonitoring to manage renal function in patients with chronic kidney disease (CKD) is recommended by health authorities. However, despite these recommendations, the adoption of telemonitoring by both health care professionals and patients faces numerous challenges.

Objective: This study aims to identify barriers and facilitators in the implementation of a telemonitoring program for patients with CKD, as perceived by health care professionals and patients, and to explore factors associated with the adoption of the program.
