MAFLD but not MASLD increases risk of all-cause mortality in regional Australia, with components of metabolic syndrome exacerbating factors: 20 year longitudinal, cohort study.

Background And Aims: Controversy remains whether the mortality risk in people with fatty liver disease (FLD) including metabolic-(dysfunction) associated steatotic liver disease (MASLD) and metabolic-(dysfunction) associated fatty liver disease (MAFLD) is higher than observed in those without FLD. We aimed to determine the mortality rate and mortality rate ratio (MRR) for these FLDs.

Methods: The study population was a randomly selected cohort of community-dwelling adults in regional Victoria, Australia between 2001 and 2003 with sufficient data evaluable for Fatty Liver Index and determination on alcohol consumption.

Quality of care in hepatocellular carcinoma-A critical review.

There is significant variation in HCC management across different centers with poor adherence to evidence-based clinical practice guidelines as assessed in prior studies. In Australia, quality indicators (QIs) have recently been proposed by a multidisciplinary group of experts to help provide a framework to assess and monitor the quality of HCC care. In this review, we discuss the many areas where real-world practice deviates from evidence-based medicine, the role that QI sets play in addressing this gap, and the similarities and differences between Australian QIs and other leading treatment guidelines and QI sets from around the world.

Associations between MASLD, atrial fibrillation, cardiovascular events, mortality and aspirin use in older adults.

The impact of metabolic dysfunction-associated steatotic liver disease (MASLD), the preferred nomenclature for NAFLD, on cardiovascular health and mortality among older adults is uncertain. As such, we aimed to identify whether MASLD increases the risk of Major Adverse Cardiovascular Events (MACE) (a composite of fatal coronary heart disease [excluding heart failure], nonfatal myocardial infarction, or fatal or nonfatal ischemic stroke), Atrial Fibrillation (AF), or all-cause mortality in older adults, and whether aspirin attenuates these risks in individuals with MASLD. This is a non-prespecified post-hoc analysis of the ASPREE (ASPirin in Reducing Events in the Elderly) randomized trial.

Validation of serum non-invasive tests of liver fibrosis as prognostic markers of clinical outcomes in people with fatty liver disease in Australia.

Background And Aim: The validity of non-invasive tests (NITs) of liver fibrosis for the prediction of liver and mortality outcomes in an Australian cohort is unknown. We aimed to verify the utility of available NITs to predict overall and cause-specific mortality and major adverse liver outcome (MALO).

Methods: This was an analysis from the Crossroads 1 clinic sub-study of a randomly sampled adult cohort from regional Australia between 2001 and 2003.

P multi-echo MRSI with low B dual-band refocusing RF pulses.

P magnetic resonance spectroscopy (MRS) can spectrally resolve metabolites involved in phospholipid metabolism whose levels are altered in many cancers. Ultra-high field facilitates the detection of phosphomonoesters (PMEs) and phosphodiesters (PDEs) with increased SNR and spectral resolution. Utilizing multi-echo MR spectroscopic imaging (MRSI) further enhances SNR and enables T information estimation per metabolite.

Mediterranean Diet and Ultra-Processed Food Intake in Older Australian Adults-Associations with Frailty and Cardiometabolic Conditions.

Dietary patterns contribute to overall health and diseases of ageing but are understudied in older adults. As such, we first aimed to develop dietary indices to quantify Mediterranean Diet Score (MDS) utilisation and Ultra-processed Food (UPF) intake in a well-characterised cohort of relatively healthy community-dwelling older Australian adults. Second, we aimed to understand the relationship between these scores and the association of these scores with prevalent cardiometabolic disease and frailty.

Initial Trans-Arterial Chemo-Embolisation (TACE) Is Associated with Similar Survival Outcomes as Compared to Upfront Percutaneous Ablation Allowing for Follow-Up Treatment in Those with Single Hepatocellular Carcinoma (HCC) ≤ 3 cm: Results of a Real-World Propensity-Matched Multi-Centre Australian Cohort Study.

Percutaneous ablation is recommended in Barcelona Clinic Liver Cancer (BCLC) stage 0/A patients with HCC ≤3 cm as a curative treatment modality alongside surgical resection and liver transplantation. However, trans-arterial chemo-embolisation (TACE) is commonly used in the real-world as an initial treatment in patients with single small HCC in contrast to widely accepted clinical practice guidelines which typically describe TACE as a treatment for intermediate-stage HCC. We performed this real-world propensity-matched multi-centre cohort study in patients with single HCC ≤ 3 cm to assess for differences in survival outcomes between those undergoing initial TACE and those receiving upfront ablation.

Serum Transaminases and Older Adults: Distribution and Associations With All-Cause Mortality.

Background: Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are commonly ordered tests in general medical practice. However, their distribution and significance in older adults are understudied. As such, we aimed to evaluate sex-stratified distribution of both ALT and AST in older adults (≥70 years) and assess for associations with mortality.

AI-powered prediction of HCC recurrence after surgical resection: Personalised intervention opportunities using patient-specific risk factors.

Background: Hepatocellular carcinoma (HCC) recurrence following surgical resection remains a significant clinical challenge, necessitating reliable predictive models to guide personalised interventions. In this study, we sought to harness the power of artificial intelligence (AI) to develop a robust predictive model for HCC recurrence using comprehensive clinical datasets.

Methods: Leveraging data from 958 patients across multiple centres in Australia and Hong Kong, we employed a multilayer perceptron (MLP) as the optimal classifier for model generation.

Rotational thromboelastometry predicts future bleeding events in patients with cirrhosis.

Background And Aims: Patients with cirrhosis of the liver are in a delicate state of rebalanced haemostasis and are at risk of developing both bleeding and thrombotic complications. Conventional haemostatic tests are unable to predict bleeding and thrombosis in these patients. We aimed to explore the role of Rotational Thromboelastometry (ROTEM) in predicting bleeding and thrombotic events in patients with cirrhosis.

NAFLD and MAFLD independently increase the risk of major adverse cardiovascular events (MACE): a 20-year longitudinal follow-up study from regional Australia.

Background And Aims: The association between fatty liver disease (FLD) and cardiovascular disease (CVD) in an Australian context has yet to be defined. The primary aim of this study was to investigate the association between FLD and 3-point major adverse cardiovascular events (MACE).

Methods: This was a longitudinal follow-up study of a randomly sampled adult cohort from regional Australia between 2001 and 2003.

Different Patterns of Care and Survival Outcomes in Transplant-Centre Managed Patients with Early-Stage HCC: Real-World Data from an Australian Multi-Centre Cohort Study.

The management of early-stage hepatocellular carcinoma (HCC) is complex, with multiple treatment strategies available. There is a paucity of literature regarding variations in the patterns of care and outcomes between transplant and non-transplant centres. We conducted this real-world multi-centre cohort study in two liver cancer referral centres with an integrated liver transplant program and an additional eight non-transplant HCC referral centres across Australia to identify variation in patterns of care and key survival outcomes.

Indirect H-[C] MRS of the human brain at 7 T using a C-birdcage coil and eight transmit-receive H-dipole antennas with a 32-channel H-receive array.

The neuronal tricarboxylic acid and glutamate/glutamine (Glu/Gln) cycles play important roles in brain function. These processes can be measured in vivo using dynamic H-[C] MRS during administration of C-labeled glucose. Proton-observed carbon-edited (POCE) MRS enhances the signal-to-noise ratio (SNR) compared with direct C-MRS.

Surveillance MRI is associated with improved survival in patients with primary sclerosing cholangitis.

Background: The benefits of regular surveillance imaging for cholangiocarcinoma in patients with primary sclerosing cholangitis (PSC) are unclear. Hence, we aimed to evaluate the impact of regular magnetic resonance cholangiopancreatography (MRCP) on outcomes of patients with PSC in Australia, where the practice of MRCP surveillance is variable.

Methods: The relationship between MRCP surveillance and survival outcomes was assessed in a multicenter, retrospective cohort of patients with PSC from 9 tertiary liver centers in Australia.

WFUMB Guidelines/Guidance on Liver Multiparametric Ultrasound. Part 2: Guidance on Liver Fat Quantification.

The World Federation for Ultrasound in Medicine and Biology (WFUMB) has promoted the development of this document on multiparametric ultrasound. Part 2 is a guidance on the use of the available tools for the quantification of liver fat content with ultrasound. These are attenuation coefficient, backscatter coefficient, and speed of sound.

Measurement of metabolite levels and treatment-induced changes in hepatic metastases of gastro-esophageal cancer using 7-T phosphorus magnetic resonance spectroscopic imaging.

Methods for early treatment response evaluation to systemic therapy of liver metastases are lacking. Tumor tissue often exhibits an increased ratio of phosphomonoesters to phosphodiesters (PME/PDE), which can be noninvasively measured by phosphorus magnetic resonance spectroscopy (P MRS), and may be a marker for early therapy response assessment in liver metastases. However, with commonly used P surface coils for liver P MRS, the liver is not fully covered, and metastases may be missed.

P MR Spectroscopy in the Pancreas: Repeatability, Comparison With Liver, and Pilot Pancreatic Cancer Data.

Background: Non-invasive evaluation of phosphomonoesters (PMEs) and phosphodiesters (PDEs) by 31-phosphorus MR spectroscopy (P MRS) may have potential for early therapy (non-)response assessment in cancer. However, P MRS has not yet been applied to investigate the human pancreas in vivo.

Purpose: To assess the technical feasibility and repeatability of P MR spectroscopic imaging (MRSI) of the pancreas, compare P metabolite levels between pancreas and liver, and determine the feasibility of P MRSI in pancreatic cancer.

Metabolic-associated fatty liver disease and hepatocellular carcinoma: a prospective study of characteristics and response to therapy.

Background And Aim: The rising incidence of hepatocellular carcinoma (HCC) in Australia is related to increasing rates of metabolic-associated fatty liver disease (MAFLD). This study aimed to prospectively characterize the metabolic profile, lifestyle, biometric features, and response to treatment of HCC patients in an Australian population.

Method: Multicenter prospective cohort analysis of newly diagnosed HCC patients at six multidisciplinary team meetings over a 2-year period.

Metabolic and transcriptomic characterization of summer and winter dormancy in the solitary bee, Osmia lignaria.

The solitary bee Osmia lignaria is a native pollinator in North America with growing economic importance. The life cycle of O. lignaria provides a unique opportunity to compare the physiological and molecular mechanisms underlying two ecologically contrasting dormancies within the same species.

Late-Life Metabolic Dysfunction-Associated Steatotic Liver Disease and its Association With Physical Disability and Dementia.

Background: The burden of metabolic dysfunction-associated steatotic liver disease (MASLD) is growing rapidly, including among older adults. The number of older adults is also rising with concomitantly increasing rates of age-related physical and cognitive dysfunction. However, data on whether MASLD affects physical and cognitive function in older adults is limited.

Improved Survival Outcomes with Surgical Resection Compared to Ablative Therapy in Early-Stage HCC: A Large, Real-World, Propensity-Matched, Multi-Centre, Australian Cohort Study.

The optimal treatment approach in very-early and early-stage hepatocellular carcinoma (HCC) is not precisely defined, and there is ambiguity in the literature around the comparative efficacy of surgical resection versus ablation as curative therapies for limited disease. We performed this real-world propensity-matched, multi-centre cohort study to assess for differences in survival outcomes between those undergoing resection and those receiving ablation. Patients with Barcelona Clinic Liver Cancer (BCLC) 0/A HCC first diagnosed between 1 January 2016 and 31 December 2020 who received ablation or resection as initial treatment were included in the study.
