Article Synopsis
  • The link between chronic kidney disease (CKD) and cognitive function is gaining attention, particularly focusing on the effects of antibacterial agents (ABs) used in CKD patients who are more prone to infections.
  • This review highlights how ABs can have direct neurotoxic effects on the central nervous system (CNS) and discusses how these medications can also alter gut microbiota, impacting cognitive symptoms through the brain-gut-kidney axis.
  • The findings emphasize the need for careful monitoring of AB therapies in CKD patients to manage adverse drug reactions, particularly antibiotic-associated encephalopathy.

Article Synopsis
  • The study investigates how healthcare professionals (HCPs) across 40 European countries manage medication adherence (MA), which is crucial for patient care and outcomes.
  • Data was collected from 2,875 HCPs through an online survey, revealing that most assess MA via direct communication and patient records, with physicians and nurses more aware of MA issues than pharmacists.
  • The findings highlight the need for improved MA assessment and reporting, particularly involving pharmacists, while suggesting a greater emphasis on technological solutions to enhance medication adherence efforts in clinical practice.

Background: Medication adherence is essential for the achievement of therapeutic goals. Yet, the World Health Organization estimates that 50% of patients are nonadherent to medication and this has been associated with 125 billion euros and 200,000 deaths in Europe annually.

Objective: This study aimed to unravel barriers and unmet training needs regarding medication adherence management across Europe.

Background And Hypothesis: There seems to be a lack of consensus on the necessity and the modality of psychological and specifically cognitive assessment of candidates for kidney transplantation. Both points are often delegated to individual hospitals/centres, whereas international guidelines are inconsistent. We think it is essential to investigate professionals' opinions to advance towards a consistent clinical practice.

Article Synopsis
  • * The growing number of CKD patients is expected to heighten the incidence of MCI, creating a substantial burden on individuals, families, and society; however, the exact causes and mechanisms behind this connection remain unclear.
  • * There is an urgent need for research to identify the underlying pathogenesis and find new therapeutic options, which will involve developing experimental models using animals like mice, rats, and zebrafish to study kidney function and cognitive issues effectively.

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.

There is growing evidence that chronic kidney disease (CKD) is an independent risk factor for cognitive impairment, especially due to vascular damage, blood-brain barrier disruption and uremic toxins. Given the presence of multiple comorbidities, the medication regimen of CKD patients often becomes very complex. Several medications such as psychotropic agents, drugs with anticholinergic properties, GABAergic drugs, opioids, corticosteroids, antibiotics and others have been linked to negative effects on cognition.

Article Synopsis
  • People with chronic kidney disease (CKD) often experience cognitive problems due to various factors, including medication side effects.
  • The complexity of treating CKD patients increases due to polypharmacy, as they usually have multiple health issues requiring numerous medications, which raises the risk of adverse drug reactions.
  • The review emphasizes two main points: CKD can disrupt the blood-brain barrier, and impaired kidney function can alter how drugs are processed in the body, leading to higher risks for issues affecting the central nervous system.

Chronic kidney disease (CKD) affects approximately 850 million people globally and is associated with an increased risk of cognitive impairment. The prevalence of cognitive impairment among CKD patients ranges from 30 to 60%, and the link between CKD and cognitive impairment is partially understood. Methodological challenges and biases in studying cognitive function in CKD patients need to be addressed to improve diagnosis, treatment, and management of cognitive impairment in this population.

Kidney dysfunction can profoundly influence many organ systems, and recent evidence suggests a potential role for increased albuminuria in the development of mild cognitive impairment (MCI) or dementia. Epidemiological studies conducted in different populations have demonstrated that the presence of increased albuminuria is associated with a higher relative risk of MCI or dementia both in cross-sectional analyses and in studies with long-term follow-up. The underlying pathophysiological mechanisms of albuminuria's effect are as yet insufficiently studied, with several important knowledge gaps still present in a complex relationship with other MCI and dementia risk factors.

Article Synopsis
  • Metabolic acidosis is common in advanced chronic kidney disease (CKD) and affects 10-50% of patients, potentially harming cognitive and motor functions.
  • Recent studies suggest that acidosis might be a modifiable factor contributing to cognitive dysfunction in CKD patients, such as memory and attention issues.
  • The review highlights the need for further research to understand how acidosis impacts the brain and to improve treatment options for cognitive impairment in CKD.

Chronic kidney disease (CKD) perturbs the crosstalk with others organs, with the interaction between the kidneys and the heart having been studied most intensively. However, a growing body of data indicates that there is an association between kidney dysfunction and disorders of the central nervous system. In epidemiological studies, CKD is associated with a high prevalence of neurological complications, such as cerebrovascular disorders, movement disorders, cognitive impairment and depression.

Little is known about metabolic syndrome (MetS)-associated cardiomyopathy, especially in relation to the role and contribution of beta-adrenoceptor (β-AR) subtypes. Therefore, we examined the roles of β-AR subtypes in the cardiac function of rats with MetS (MetS group) and compared it with that of rats with streptozotocin (STZ)-induced diabetes (STZ group). Compared with the normal control rats, the protein levels of cardiac β1- and β2-AR in the MetS group were significantly decreased and with no changes in their mRNA levels, whereas the protein levels of β3-AR were similar to those of the controls.

Objective: To detect the possible alterations on density or sensitivity of α1-adrenergic subtypes in diabetic bladder by reverse transcriptase-polymerase chain reaction technology and in vitro studies.

Methods: Experimental diabetes was induced by administration of streptozotocin with a single injection through the tail vein. Rats were divided into control and diabetic groups.

Introduction: In this study, we aimed to evaluate changes in contractile responses under in vitro conditions in detrusor overactivity (DO) in patients with bladder outflow obstruction (BOO).

Materials And Methods: Detrusor strips obtained during open prostatectomy procedure from 16 patients with BOO related to benign prostate hyperplasia were evaluated under in vitro conditions. Patients were assigned to two groups as patients with (DO) and without (no DO) DO.

Aim: It is known that physiopathological changes in diabetes affect the function of the bladder. In this study, we aimed to demonstrate the possible effects of diabetes on the urothelium during this physiopathological process.

Methods: Diabetes was induced in rats by tail vein injection of 35 mg/kg streptozotocin.

Introduction: Our goal was to investigate the effects of arsenic sulfur (AsS) on the detrusor smooth muscle reactivity.

Material And Methods: AsS (100 ppm microg/g) in drinking water was administered for 2 weeks to two groups of female Wistar rats. The contractile responses of urinary bladders to electrical field stimulation, carbachol, ATP and KCl, and the relaxant responses to ATP, adenosine and isoproterenol were examined.
