Objectives: There is growing evidence for cognitive dysfunction in chronic hemodialysis patients as the age and the prevalence of comorbidities increase in this population. The aim of the present study was to assess cognitive performance in hemodialysis patients and determine the variables associated with poor cognitive function.
Methods: Cross-sectional cohort of 108 maintenance hemodialysis patients in the Marrakech area. Cognitive performance was assessed through the mini mental state examination (MMSE). Cognitive impairment was defined as a score of less than 24. Univariate and multivariate analyses were performed to determine the variables associated with MMSE score.
Results: We found that 25% of the subjects were cognitively impaired. After adjusting for demographic and medical variables, low MMSE scores were independently associated with educational level (odd ratio: 0.564; p = 0.031) and anemia (odd ratio: 0.743; p = 0.046).
Conclusion: There is a high prevalence of cognitive dysfunction among hemodialysis patients and many causative factors have been evoked. Effective identification of this trouble allows adequate psychological interventions to improve the quality of life of these patients.

Background: Pregnancy-associated atypical hemolytic uremic syndrome (aHUS) is a form of thrombotic microangiopathy (TMA) caused by uncontrolled activation of the complement system during pregnancy or the postpartum period. In the intensive care unit, aHUS must be differentiated from sepsis-related multiple organ dysfunction, thrombotic thrombocytopenic purpura (TTP), hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome. Early recognition of aHUS is critical for effective treatment and improved prognosis.

Background: Patients treated with chronic dialysis or kidney transplantation have difficulties in maintaining employment. We aimed to estimate employment rates among dialysis and kidney transplant patients from 3 years before to 3 years after initiating dialysis or undergoing transplantation.
Methods: All first-time dialysis and kidney transplantation patients aged 18-65 years in Denmark from 2005 to 2019 were identified using the Danish Nephrological Register and linked with information about social security benefits.

Background: Creatinine-based estimated glomerular filtration rate (eGFR) equations are widely used in clinical practice but exhibit inherent limitations. On the other side, measuring GFR is time consuming and not available in routine clinical practice. We developed and validated machine learning models to assess the trustworthiness (i.

Chronic kidney disease (CKD) is defined by persistent abnormalities of kidney function or structure that have consequences for the health. A progressive decline of excretory kidney function has effects on body homeostasis. CKD is tightly associated with accelerated cardiovascular disease and severe infections, and with premature death.
