Prevalence, Types and Recognition of Cognitive Impairment in Dialysis Patients in South Eastern Sydney

Abstract

In international studies, cognitive impairment is a common but underdetected issue in dialysis patients. Chronic Kidney Disease (CKD) shares risk factors with and is an independent risk factor for cognitive impairment. There is a lack of Australian data of cognitive impairment in this at-risk population. This has implications on service planning because cognitive impairment in CKD is associated with higher mortality, morbidity, and healthcare costs. This study examines the prevalence, types, and clinician recognition of cognitive impairment within an Australian dialysis population. A cross-sectional study of haemodialysis and peritoneal dialysis patients in South-East Sydney screened for cognitive impairment using the Montreal Cognitive Assessment (MoCA). Participant interviews, medical records, physician and carer questionnaires, were used to determine the types of cognitive impairment and rate of recognition. 106 participants were included (median age 66 years, median dialysis duration 2 years) and 58 (54.7%) were cognitively impaired on the MoCA, of whom old age psychiatrists subclassified 21 (36.2%) as having dementia, and 31 (53.4%) with 'Cognitive Impairment, No Dementia'. 36/58 (62.0%) of the cognitively impaired partici...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
