Aim: To examine the epidemiology of cardiac arrest (CA) in New South Wales (NSW), Australia, and a large teaching hospital in Sydney and to identify predictors of survival.
Methods: Data from the 1996/97 NSW inpatient statistics collection were analysed. Logistic regression was used to determine predictors of mortality from CA.
Results: In 1996/97 in public hospitals, Eastern Sydney Area Health Service (AHS) (47.5), and in private hospitals of Macleay-Hastings District Health Services (DHSs), recorded the highest crude CA rates in NSW with figures of 47.5 and 21.3 per 10,000 hospital separations. Standardised CA rates were highest in Western Sydney, Illawara, Macleay-Hasting, Mid North Coast and Orana DHSs. Most CAs in hospital 'X' occurred after admission and 55.7% occurred in patients admitted with a non-cardiac principal diagnosis, mainly pneumonia. Acute myocardial infarction was the leading diagnosis (28.9%) in patients who suffered CA after admission. Only 32% of CA patients survived to discharge. Age above 65 (odds ratio (OR)=2.284, P=0.006) had the highest effect on cardiac mortality. The longer the patients were in the intensive care unit (OR=0.997, P=0.037), the more likely they were to survive.
Conclusion: We describe considerable variation in CA rates in NSW. The majority of hospital CAs occur at or soon after admission, and are associated with underlying non-cardiac conditions. Survival following hospital CA is low, but there may be preventable elements. Knowledge of risk factors and epidemiology of hospital CAs may help identify patients at risk of CA.

Validating a Case Definition for Transgender Adults Using Administrative Data.

Importance: Administrative health data serve as promising data sources to study transgender health at a population level in the absence of self-reported gender identity.
Objective: To develop and validate case definitions identifying transgender adults in administrative data compared with the reference standard of self-reported gender identity in a universal health care setting.
Design, Setting, And Participants: In this cohort study conducted in Alberta, Canada, data from provincial administrative health data sources including inpatient hospitalizations, emergency department encounters, primary care visits, prescription drug dispensations, and the provincial health insurance registry were linked and used to develop 15 case definitions (9 for transgender women and 6 for transgender men).
Background: Single-nucleus RNA sequencing (snRNAseq) allows for the dissection of the cell type-specific transcriptional profiles of tissue specimens. In this study, we compared gene expression in multiple brain cell types in brain tissue from Alzheimer disease (AD) cases with no or other co-existing pathologies including Lewy body disease (LBD) and vascular disease (VaD).
Method: We evaluated differential gene expression measured from single nucleus RNA sequencing (snRNAseq) data generated from the hippocampus region tissue donated by 11 BU ADRC participants with neuropathologically confirmed AD with or without a co-existing pathology (AD-only = 3, AD+VaD = 6, AD+LBD = 2).

Background: Alzheimer's disease (AD) has both genetic and environmental risk factors. Gene-environment interaction may help explain some missing heritability. There is strong evidence for cigarette smoking as a risk factor for AD.

Background: Cardio and cerebrovascular risk factors (CVRFs) increase the risk of cerebrovascular disease and clinical Alzheimer's Disease (AD), and over 70% of the patients with AD coincident cerebrovascular pathology. We previously found that FMNL2 interacts with a burden score of hypertension, diabetes, heart disease, and body mass index (BMI) by altering the normal astroglial-vascular mechanisms that underly amyloid clearance. Stroke, defined by history of a clinical stroke or brain imaging, is a moderately robust risk factor for AD and dementia.

Background: There is growing evidence that epigenetic age acceleration may predict late life cognitive decline and dementia, but it is unknown whether this is due to accelerated neurodegeneration or reduction in cognitive resilience. We examined the relationship between epigenetic clocks and domain specific neuropsychological (NP) factor scores, mild cognitive impairment (MCI), Alzheimer's Disease (AD), and all-cause dementia, before and after accounting for plasma total tau (t-tau), a marker of neurodegeneration.
Method: DNA methylation and plasma t-tau (Simoa assay; Quanterix) data from 2091 Framingham Heart Study Offspring cohort participants were generated from blood at the same Exam 8 visit (2005-2008).
