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 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.

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.

Topoisomerase (IIB) inhibitors have been involved in the therapies of tumour progression and have become a major focus for the development of anticancer agents. New three-component hybridised ligands, 1,4-disubstituted-1,2,3-triazoles (-), were synthesised via a 1,3-dipolar cycloaddition reaction of 9-azidoacridine/3-azidocoumarin with N/O-propargyl small molecules under click reaction conditions. Cancer cell growth inhibition of the synthesised triazoles was tested against human cell-lines in the NCI-60-cell-panel, and the most active compounds tested against topoisomerase (IIB)-enzymes.

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.

  • 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.
