Abstract

Acute coronary syndrome (ACS) is one of the leading causes of mortality in the renal replacement therapy (RRT) population. We aimed to understand the characteristics, trends and outcomes of ACS in our local RRT population as a means to improve care and outcomes for this high-risk population. Using the ANZACS-QI database, we conducted a retrospective analysis of all ACS occurring in RRT patients between 1 January 2010-31 December 2019 managed at Waikato Hospital (n=135 at index ACS). In our cohort made up predominantly of Māori (55%) and European (34%) patients, 58% had diabetic nephropathy as their primary disease. Twenty-seven percent presented atypically and 65% had a delay of >72 hours from diagnosis to angiogram. There was a 49% mortality rate at one year post-index ACS. Factors associated with mortality at one year included: atypical presentation (chi-square statistic (X2) 7.250; p=0.0071), troponin delta >20% (X2 5.682; p=0.0171), peak troponin (point biserial correlation; r=0.2086; p=0.0473) and no revascularisation (X2 5.2419; p=0.0221). The findings in our cohort reiterate that patients on RRT are a vulnerable population who have poor outcomes associated with ACS, driven by multifactorial delays in diagnosis and treatm...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.
