cognitive impairment and CKD

Patients with chronic kidney disease (CKD) often experience mild cognitive impairment and other neurocognitive disorders. Studies have shown that erythropoietin (EPO) and its receptor have neuroprotective effects in cell and animal models of nervous system disorders. Recombinant human EPO (rHuEPO), commonly used to treat anemia in CKD patients, could be a neuroprotective agent. In this systematic review, we aimed to assess the published studies investigating the cognitive benefits of rHuEPO treatment in individuals with reduced kidney function...

Since prevention, early detection, and treatment of blood pressure improve public health, the aim of present study was to determine the best obesity indices and estimate the optimal cut-off point for each one to predict the risk of elevated/stage 1 and undiagnosed hypertension in the population of center of Iran based on American ACC/AHA 2020 guidelines...

INTRODUCTION: Growing evidence suggests a causal role for atherosclerotic vascular disease in cognitive impairment and dementia. Atherosclerosis may present as monovascular disease (monoVD) or as widespread polyvascular atherosclerotic disease (polyVD). Evidence on the relationship between monoVD or polyVD and cognitive impairment is limited. METHODS: We conducted a cross-sectional analysis of baseline data from the LipidCardio Study. The main outcome measure was the presence of cognitive impairment, defined as a Mini-Mental State Examination (MMSE) score < 26...

Chronic kidney disease is a universal topic gravitating towards various aspects of widespread illness, impacting the overall well-being of human beings. Patients with longstanding renal complaints under dialysis encounter challenges correlated with physical, intuitive, and socio-economic conditions to a greater extent in their daily existence. These portions may include changes in the appearance of a person, restricted physique movements, curbed diet, duration of surgical protocols, travelling time during the period of prevention, financial load, role reversal in the family followed by ruining their livelihood, deprived social rank, difficulty in relational, cordial relationships, and so on...

BACKGROUND: This study aimed to evaluate the correlation between serum methylmalonic acid (MMA) levels and cognition function in patients with chronic kidney disease (CKD). METHODS: In this cross-sectional study, we included 537 CKD individuals aged ≥ 60-year-old with albuminuria from the National Health and Nutrition Examination Survey (NHANES) 2011-2014. Four cognitive tests including the Digit Symbol Substitution Test (DSST), the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) Delayed Recall and Word Learning tests, and the Animal Fluency test (AF) were performed...

IMPORTANCE: Dementia and hepatic encephalopathy (HE) are challenging to distinguish clinically. Undiagnosed cirrhosis in a patient with dementia can lead to missed opportunities to treat HE. OBJECTIVE: To examine the prevalence and risk factors of undiagnosed cirrhosis and therefore possible HE in veterans with dementia. DESIGN, SETTING, AND PARTICIPANTS: A retrospective cohort study was conducted between 2009 and 2019 using data from the Veterans Health Administration (VHA) and 2 separate validation cohorts from the Richmond Veterans Affairs Medical Center...

OBJECTIVE: Hypertensive disorders of pregnancy (HDP), including preeclampsia (PE) are associated with an increased risk of maternal cardiovascular disease, stroke and chronic kidney disease. However, their association with subsequent maternal dementia or cognitive impairment is less well understood. To review and synthesize the published literature on HDP and subsequent risk of maternal dementia or cognitive impairment. DATA SOURCES: PubMed, Web of Science, Pyschinfo and CINAHL from database inception until July 31st 2022, for observational studies of HDP and maternal dementia or cognitive impairment...

Diabetes mellitus (DM) and chronic kidney disease (CKD) are common in middle aged and older adult individuals. DM may accelerate the aging process, and the age-related declines in the estimated glomerular filtration rate (eGFR) can pose a challenge to diagnosing diabetic kidney disease (DKD) using standard diagnostic criteria especially with the absence of severe albuminuria among older adults. In the presence of CKD and DM, older adult patients may need multidisciplinary care due to susceptibility to various health issues, e...

BACKGROUND: Cognitive impairment (CI) is one of the major complications in chronic kidney disease patients, especially those with end-stage renal disease (ESRD). Limited biomarkers have been found that can significantly predict ESRD-associated cognitive decline. OBJECTIVE: This cohort study aimed to investigate de novo biomarkers for diagnosis of the ESRD-associated CI. METHODS: In this cohort study, qualified samples were divided into control (with an estimated glomerular filtration rate (eGFR) of≥60 mL/min and a Mini-Mental State Examination (MMSE) score of >  27), ESRD without CI (eGFR <  15 and MMSE >  27), and ESRD with CI (eGFR <  15 and MMSE <  27) groups...

Drug-induced hypomagnesemia is an adverse effect with the potential for serious and fatal outcomes. Although rare, chronic use of proton pump inhibitors (PPIs) can cause hypomagnesemia due to impaired intestinal absorption, mainly attributed to reduced transcellular transport of magnesium via transient receptor potential melastatin 6 (TRPM6) and 7 (TRPM7) channels. However, a reduction of magnesium paracellular absorption due to the downregulation of intestinal claudins has also been reported. PPI-induced hypomagnesemia can trigger other concomitant electrolyte derangements, including hypokalemia, hypocalcemia, hypophosphatemia, and hyponatremia...
