Assessment of kidney function in oncology patients is a fundamental factor in profiling the survival risk, determining the appropriate dose of chemotherapeutic drugs, and defining a patient eligibility for clinical trials with novel agents. Both overestimation and underestimation of kidney function may affect the treatment efficacy and outcomes. Overestimation may lead to overdosing or inappropriate agent selection and the corresponding toxicity, whereas underestimation may be responsible for underdosing or inappropriate agent exclusion and subsequent treatment failure...

The inappropriate over-activation of the with-no-lysine kinase (WNK)-STE20/SPS1-related proline/alanine-rich kinase (SPAK)-sodium chloride cotransporter (NCC) phosphorylation cascade increases sodium reabsorption in distal kidney nephrons, resulting in salt-sensitive hypertension. Although chronic kidney disease (CKD) is a common cause of salt-sensitive hypertension, the involvement of the WNK phosphorylation cascade is unknown. Moreover, the effect of immune systems on WNK kinases has not been investigated despite the fact that immune systems are important for salt sensitivity...

Bariatric surgery improves markers of kidney health in severe obesity, yet it is unclear if kidney disease outcomes differ according to age at surgery. Therefore, we examined health effects of Roux-en-Y gastric bypass between 161 adolescents and 396 adults participating in two related but distinct studies. Primary outcomes were elevated urine albumin-to-creatinine ratio (UACR) of 30 mg/g or more and hyperfiltration (an estimated glomerular filtration rate of 135 ml/min/1.73m2 or more). Analyses were stratified by the presence of pre-operative type 2 diabetes...

B-cell depletion with anti-CD20 monoclonal antibodies is widely used for the treatment of autoimmune diseases. This review will discuss mechanisms contributing to success or failure of B-cell depletion therapy in antibody-mediated autoimmune diseases. It will also explain how key information about disease pathogeny can be provided by the different outcomes observed after B-cell depletion therapy. These findings provide the basis for future innovative therapeutic strategies aiming at an optimized B cell and/or plasma cell depletion to increase long-term disease remission...

With the emergence of electronic health records, the reuse of clinical data offers new perspectives for the diagnosis and management of patients with rare diseases. However, there are many obstacles to the repurposing of clinical data. The development of decision support systems depends on the ability to recruit patients, extract and integrate the patients' data, mine and stratify these data, and integrate the decision support algorithm into patient care. This last step requires an adaptability of the electronic health records to integrate learning health system tools...

Chronic Kidney Disease (CKD) is increasing in incidence and has become a worldwide health problem. Sleep disorders are prevalent in patients with CKD raising the possibility that these patients have a disorganized circadian timing system. Here, we examined the effect of adenine-induced tubulointerstitial nephropathy on the circadian system in mice. Compared to controls, adenine-treated mice showed serum biochemistry evidence of CKD as well as increased kidney expression of inflammation and fibrosis markers...
