The prevalence of chronic kidney disease (CKD) is increasing, and the epidemic of obesity is one of the causes. Obesity exacerbates hypertension as a risk factor for CKD, causing vasoconstriction and salt and water retention. Obesity also worsens glucose intolerance and insulin resistance as risk factors for CKD. Obesity targets the kidney by triggering novel pathways of intrarenal inflammation, recruiting professional immunologic cells through metaflammation. Obesity-related glomerulopathy has emerged as a distinct pathologic variant of focal segmental glomerulosclerosis. No definitive treatments have come about for obesity-related glomerulopathy, but among the most promising prospects is aggressive weight loss, including bariatric surgery.

Search for surrogate markers to predict end stage kidney disease in long term lithium users.
Int J Bipolar Disord
January 2025
Department of Nephrology, Jeroen Bosch Ziekenhuis, 's-Hertogenbosch, The Netherlands.
Background: A surrogate marker (a substitute indicator of the true outcome) is needed to predict subgroups of long-term lithium users at risk of end-stage kidney disease (ESKD). In this narrative review the aim is to determine the optimal surrogate endpoint for ESKD in long-term lithium users in a scientific context. MAIN: In a literature search in long-term lithium users, no studies on surrogate measurements on ESKD were identified.

Background: Adolescents and young adults (AYA) with germline CDH1 variants are at risk of overtreatment when precancer lesions are detected with endoscopic screening. We characterize diffuse-type gastric cancer prevalence and survival in AYA managed with prophylactic total gastrectomy (PTG) or endoscopic surveillance.
Methods: Prospective cohort study of 188 individuals aged 39 and younger enrolled from January 27, 2017, to May 1, 2023.
Introducing robot-assisted kidney transplantation in a high-volume centre in Denmark: a pilot and feasibility study.

Robot-assisted kidney transplantation (RAKT) may reduce surgical complications compared to open kidney transplantation (OKT), but no randomised trials have explored this to date. The aim of the present study is to explore the feasibility of introducing RAKT at our institution, making it available in deceased donor transplantation and evaluate early surgical outcomes prior to performing a randomised trial comparing RAKT to OKT. RAKT was performed at Department of Urology, Copenhagen University Hospital, Rigshospitalet, Denmark.

Mono(ADP-ribosyl)ation (MARylation) is emerging as a critical regulator of ribosome function and translation. Herein, we demonstrate that RACK1, an integral component of the ribosome, is MARylated by the mono(ADP-ribosyl) transferase (MART) PARP14 in ovarian cancer cells. MARylation of RACK1 is required for stress granule formation and promotes the colocalization of RACK1 in stress granules with G3BP1, eIF3η, and 40S ribosomal proteins.

Unlabelled: Uremic leontiasis ossia (ULO) is a rare manifestation of renal osteodystrophy in) patients with end-stage chronic kidney disease (CKD) and secondary hyperparathyroidism (SHPTH). It occurs due to increased osteoclastic activity secondary to high plasmatic parathyroid hormone (PTH) levels. This leads to bone deformation with thickening and massive enlargement of the cranial vault, resulting in a leonine face appearance.
