Predictive Validity of Intrinsic Capacity Composite Scores for Risk of Frailty at 2 Years: A Comparison of 4 Scales.

Objective: Intrinsic capacity (IC) and frailty are complementary constructs that encapsulate functional capacities of older adults. Although earlier studies suggest the utility of composite IC scores in predicting risk of frailty, key gaps remain with the lack of direct comparative studies between different IC scales and lack of a composite score based on the World Health Organization Integrated Care for Older People (ICOPE) tool. We aimed to compare different IC scales, including an ICOPE-based scale, in their predictive ability for risk of frailty at 2 years in healthy community-dwelling older adults.

The impact of coronavirus-19 vaccination on anti-nuclear cytoplasmic antibody vasculitis hospitalisations in a Sydney health network.

There have been reports of COVID-19 vaccination triggering anti-nuclear cytoplasmic antibody (ANCA)-associated vasculitis (AAV), but no robust studies have examined the link. This retrospective cohort study assessed the impact of COVID vaccination on the rate of denovo and relapsed AAV in a Sydney Local Health District from 2018 to 2022. Despite more than 95% of the population receiving vaccination, the case rate of AAV was stable.

The Controversies of Coronary Artery Disease in End-Stage Kidney Disease Patients: A Narrative Review.

Cardiovascular disease (CVD) accounts for more than 50% of deaths among patients with end-stage kidney disease (ESKD). Approximately 40-50% of ESKD patients have clinically significant coronary artery disease (CAD) due to atherosclerosis which accounts for a significant proportion of CVD risk. However, other CVD pathologies including myocardial fibrosis, vascular calcification and arterial stiffening play important contributory roles.

The first Australian uterus transplantation procedure: A result of a long-term Australian-Swedish research collaboration.

Aims: The aim is to report the results of Australia's first uterus transplantation (UTx).

Methods: Following long-standing collaboration between the Swedish and Australian teams, Human Research Ethics approval was obtained to perform six UTx procedures in a collaborative multi-site research study (Western Sydney Local District Health 2019/ETH13038), including Royal Hospital for Women, Prince of Wales Hospital, and Westmead Hospital in New Souh Wales. Surgeries were approved in both the live donor (LD) and deceased donor models in collaboration with the inaugural Swedish UTx team.

Treatment decision-making and care among older adults with kidney failure: protocol for a multicentre, prospective observational cohort study with nested substudies and linked qualitative research (the Elderly Advanced CKD Programme).

Introduction: Shared treatment decision-making and planning of care are fundamental in advanced chronic kidney disease (CKD) management. There are limited data on several key outcomes for the elderly population including survival, quality of life, symptom burden, changes in physical functioning and experienced burden of healthcare. Patients, caregivers and clinicians consequently face significant uncertainty when making life-impacting treatment decisions.

In Vivo Confocal Microscopy in Different Types of Dry Eye and Meibomian Gland Dysfunction.

In vivo confocal microscopy (IVCM) imaging is increasingly popular in ocular surface disease diagnosis and management. We conducted a systematic review to update the use of IVCM in the diagnosis and treatment of dry eye and meibomian gland dysfunction (MGD). A literature review was conducted on IVCM studies in MGD, dry eye disease, systemic disease causing dry eye, dry eye in glaucoma patients, contact lens-associated ocular conditions, graft-versus-host disease, and Sjogren's syndrome-related dry eye.

Retrospective study on the epidemiology of antineutrophil cytoplasmic autoantibodies-associated vasculitis in two Australian health districts.

Background: Antineutrophil cytoplasmic autoantibodies (ANCA)-associated vasculitis (AAV) is more prevalent in rural Australia compared with metropolitan areas, suggesting a role of environment in disease pathogenesis. However, the prevalence of environmental risk factors in Australian AAV patients has not been described.

Aims: To compare the incidence of AAV between two health districts (Illawarra Shoalhaven Local Health District (ISLHD), a mixed rural/metropolitan region, and South Eastern Sydney Local Health District (SESLHD), a metropolitan region) in Australia and its relationship to environmental exposures.

The Effects of OMEGA-3 Fatty Acid Supplementation Upon Interleukin-12 and Interleukin-18 in Chronic Kidney Disease Patients.

Objective(s): Cardiovascular disease (CVD) remains a leading cause of mortality in chronic kidney disease (CKD) patients. Interventions targeting traditional risk factors have largely proven ineffective in CKD patients in part because of the increased role of nontraditional risk factors such as chronic inflammation. Omega-3 fatty acids (ω3FA) are inexpensive and safe natural agents, which target inflammation and have potential cardioprotective benefits.

Relationship between pulse pressure and inflammation with left ventricular diastolic dysfunction in chronic kidney disease patients.

Background: Diastolic dysfunction (DD) is an important cause of cardiovascular disease (CVD) mortality in chronic kidney disease (CKD) patients. Non-traditional risk factors, such as arterial stiffness and inflammation, are implicated in the pathogenesis of DD in CKD patients.

Aim: To determine the association between inflammatory markers (interleukin (IL)-12, IL-18, highly sensitive C-reactive protein (hsCRP)) and non-invasive markers of arterial stiffness (24-h pulse pressure (PP)) with DD in stages 3-4 CKD patients.

Increased Inflammatory Response in Association with the Initiation of Hemodialysis Compared with Peritoneal Dialysis in a Prospective Study of End-Stage Kidney Disease Patients.

Background: Large epidemiological studies have demonstrated an early survival advantage with the initiation of peritoneal dialysis (PD) compared to haemodialysis (HD). Chronic inflammation may contribute to atherosclerosis and cardiovascular (CVD) mortality in end-stage kidney disease (ESKD). We hypothesize that the initiation of HD in ESKD patients is associated with a greater inflammatory response compared with PD.

Diagnostic Accuracies of Glycated Hemoglobin, Fructosamine, and Homeostasis Model Assessment of Insulin Resistance in Predicting Impaired Fasting Glucose, Impaired Glucose Tolerance, or New Onset Diabetes After Transplantation.

Background: New onset diabetes after transplantation (NODAT) is associated with a 3-fold greater risk of cardiovascular disease events, with early identification and treatment potentially attenuating this risk. The optimal screening test to identify those with NODAT remains unclear, and the aim of this study was to examine the diagnostic accuracies of 4 screening tests in identifying impaired fasting glucose, impaired glucose tolerance (IGT), and NODAT.

Methods: This is a single-center prospective cohort study of 83 nondiabetic kidney transplant recipients between 2008 and 2011.

The impact of abnormal glucose regulation on arterial stiffness at 3 and 15 months after kidney transplantation.

Background: Post-transplant diabetes mellitus (PTDM) has been associated with an increased risk of cardiovascular disease (CVD) mortality following kidney transplantation, but the association between pre-diabetes (i.e. impaired fasting glucose and impaired glucose tolerance) and CVD mortality remains unclear.

Elevated interleukin-12 and interleukin-18 in chronic kidney disease are not associated with arterial stiffness.

Background: Chronic kidney disease (CKD) patients are at increased risk of cardiovascular disease (CVD) mortality compared to the general population. Evidence suggests inflammation is important in the pathogenesis of CVD in CKD and inflammatory bio-markers such as C-reactive protein (CRP) and pro-atherogenic cytokines such as interleukin(IL)-6, IL-12 and IL-18 are associated with CVD-related outcomes in the general population and CKD. In the general population, IL-12 and IL-18 are implicated in the pathogenesis of atherosclerosis and are associated with acute CVD events, including mortality.

Association of a change in immunosuppressive regimen with hemodynamic and inflammatory markers of cardiovascular disease after kidney transplantation.

Background: Although rejection rates and short-term graft survival have significantly improved in kidney transplantation with the introduction of calcineurin inhibitor (CNI), cardiovascular disease (CVD) and metabolic complications are being increasingly recognized as important causes of morbidity and mortality. We hypothesize that non-CNI proliferation signal inhibitor (PSI)-based immunosuppressive regimen is associated with improved arterial stiffness after kidney transplantation compared with CNI-based immunosuppressive regimens.

Methods: This is a prospective, single-center study of renal transplant (RT) recipients comparing the metabolic, cardiovascular (pulse wave velocity and aortic augmentation index (AI) adjusted for heart rate (AI × 75)), inflammatory cytokines (interleukins (ILs) 6, 12, and 18) and graft-related outcomes at 3 and 15 months posttransplantation between RT recipients maintained on CNI- (CNI-CNI) or PSI-based (CNI-PSI) regimens including sirolimus and everolimus.

Interleukin-12 is associated with arterial stiffness in healthy individuals.

Background: Atherosclerotic cardiovascular disease (CVD) is a chronic inflammatory disease mediated by the proinflammatory cytokines interleukin-12 (IL-12) and interleukin-18 (IL-18). Evidence suggests that IL-12 is dominant in early atherosclerosis, while IL-18 is critical in advanced atherosclerosis. In this study, we explore the association between IL-12 and IL-18 and arterial stiffness in healthy individuals.

Acute kidney injury: controversies revisited.

This paper addresses the epidemiology of AKI specifically in relation to recent changes in AKI classification and revisits the controversies regarding the timing of initiation of dialysis and the use of peritoneal dialysis as a renal replacement therapy for AKI. In summary, the new RIFLE/AKIN classifications of AKI have facilitated more uniform diagnosis of AKI and clinically significant risk stratification. Regardless, the issue of timing of dialysis initiation still remains unanswered and warrants further examination.

Effects of proactive iron and erythropoiesis-stimulating agent protocol implementation on achieving clinical guideline targets for anaemia in a satellite haemodialysis patient cohort.

Aim: Anaemia management with erythropoiesis-stimulating agents (ESA) and i.v. iron replacement in haemodialysis patients poses several clinical challenges, including maintaining stable haemoglobin (Hb) levels within target ranges while achieving lowest effective ESA dose.
