Results of a healthcare transition learning collaborative for emerging adults with sickle cell disease: the ST3P-UP study transition quality improvement collaborative.

Background: Individuals with sickle cell disease (SCD) experience poor clinical outcomes while transitioning from paediatric to adult care. Standards for SCD transition are needed. We established a Quality Improvement (QI) Collaborative that aimed to improve the quality of care for all young adults with SCD by establishing a standardised SCD transition process.

The impact of hepatic and splenic volumetric assessment in imaging for chronic liver disease: a narrative review.

Chronic liver disease is responsible for significant morbidity and mortality worldwide. Abdominal computed tomography (CT) and magnetic resonance imaging (MRI) can fully visualise the liver and adjacent structures in the upper abdomen providing a reproducible assessment of the liver and biliary system and can detect features of portal hypertension. Subjective interpretation of CT and MRI in the assessment of liver parenchyma for early and advanced stages of fibrosis (pre-cirrhosis), as well as severity of portal hypertension, is limited.

Computed Tomography-Derived Extracellular Volume Fraction and Splenic Size for Liver Fibrosis Staging.

Objective: Extracellular volume fraction (fECV) and liver and spleen size have been correlated with liver fibrosis stages and cirrhosis. The purpose of the current study was to determine the predictive value of fECV alone and in conjunction with measurement of liver and spleen size for severity of liver fibrosis.

Methods: This was a retrospective study of 95 subjects (65 with liver biopsy and 30 controls).

Small bowel obstruction caused by dehydrated apple ingestion: the challenges of preoperative radiological diagnosis and surgical management.

A man in his 60s with a virgin abdomen presented with sudden-onset generalised abdominal pain and fevers. The night prior, he snacked on supermarket purchased dehydrated apples. CT abdomen and pelvis revealed small bowel obstruction (SBO) to the mid ileum and small amount of free fluid within the pelvis.

Evaluating treatment response following locoregional therapy for hepatocellular carcinoma: A review of the available serological and radiological tools for assessment.

Hepatocellular carcinoma (HCC) is an aggressive primary malignancy of the liver and is the third most common cause of cancer-related global mortality. There has been a steady increase in treatment options for HCC in recent years, including innovations in both curative and non-curative therapies. These advances have brought new challenges and necessary improvements in strategies of disease monitoring, to allow early detection of HCC recurrence.

Wide variation in pre-procedural blood product transfusion practices in cirrhosis: a national multidisciplinary survey.

Background And Aims: Recent guidelines recognize the limitations of standard coagulation tests in predicting bleeding and guiding pre-procedural blood component prophylaxis in cirrhosis. It is unclear whether these recommendations are reflected in clinical practice. We performed a nationwide survey to investigate pre-procedural transfusion practices and opinions of key health care stakeholders involved in managing cirrhosis.

Radiation exposure from radiological procedures in liver transplant candidates with hepatocellular carcinoma.

Purpose: Candidates for liver transplantation (LT) with hepatocellular carcinoma (HCC) undergo a large number of diagnostic and interventional radiology procedures. A significant proportion of such procedures involve ionizing radiation with increased lifetime risk of cancer. The objective of our study was to review LT candidates with HCC to quantify ionizing radiation doses from different radiology procedures performed at a single transplant center.

Monitoring quality of care in hepatocellular carcinoma: A modified Delphi consensus.

Although there are several established international guidelines on the management of hepatocellular carcinoma (HCC), there is limited information detailing specific indicators of good quality care. The aim of this study was to develop a core set of quality indicators (QIs) to underpin the management of HCC. We undertook a modified, two-round, Delphi consensus study comprising a working group and experts involved in the management of HCC as well as consumer representatives.

Marker assisted selection for Varroa destructor resistance in New Zealand honey bees.

Varroa destructor is a honey bee (Apis mellifera) parasite identified as one of the leading causes of overwintering colony loss in New Zealand. It has been shown that a naturally occurring heritable trait, "Varroa Sensitive Hygiene" (VSH), confers an advantage to colonies by increasing behaviours that limit the survival and reproduction of Varroa mites. The SNP 9-9224292 is an adenine/guanine (A/G) polymorphism on chromosome 9 of Apis mellifera where the G allele was observed to be associated with VSH behaviour in North American honey bees.

Synoptic CT scan reporting of pancreatic adenocarcinoma to align with international consensus guidelines on surgical resectability: a Victorian pilot.

Background: Non-metastatic pancreatic ductal adenocarcinoma (PDAC) is classified as resectable (R), borderline resectable (BR) or locally advanced (LA). International Consensus Guidelines on these definitions exist, but have not been integrated into everyday Australian practice. The anatomical features on CT imaging lend themselves to synoptic reporting which should enhance completeness, comparability and consistency.

Brief lifestyle interventions for prediabetes in primary care: a service evaluation.

Background: The increasing number of cases of prediabetes in the UK is concerning, particularly in Wales where there is no standard programme of support. The aim of the current service evaluation was to examine the effectiveness of brief lifestyle interventions on glucose tolerance in people at risk of developing type 2 diabetes.

Methods: In this pragmatic service evaluation clinical data on people deemed at risk of developing type 2 diabetes were evaluated from two GP clusters.

A Pilot First-in-Human Study of Embrace, a Polyethylene Glycol-Based Liquid Embolic Agent, in the Embolization of Malignant and Benign Hypervascular Tumors.

Purpose: To investigate the safety and efficacy of an aqueous polyethylene glycol-based liquid embolic agent, Embrace Hydrogel Embolic System (HES), in the treatment of benign and malignant hypervascular tumors.

Materials And Methods: A prospective, single-arm, multicenter study included 8 patients, 5 males and 3 females, with a median age of 58.5 years (30-85 years), who underwent embolization in 8 tumors between October 2019 and May 2020.

Ultrasound-guided portal vein puncture during Transjugular Intrahepatic Portosystemic Shunt: Technique and experience of a quaternary liver transplant hospital.

Introduction: Portal hypertension (PH) is associated with complications including refractory ascites and variceal haemorrhage and can be treated endovascularly with a Transjugular Intrahepatic Portosystemic Shunt (TIPS). Portal vein puncture during TIPS using real-time transabdominal ultrasound guidance is one of many portal vein puncture techniques and is seldom used compared with other methods. The purpose of this manuscript is to describe this technique and its associated procedural outcomes at a quaternary liver transplant hospital.

A remarkable group of thick-headed Triassic Period archosauromorphs with a wide, possibly Pangean distribution.

The radiation of archosauromorph reptiles in the Triassic Period produced an unprecedented collection of diverse and disparate forms with a mix of varied ecologies and body sizes. Some of these forms were completely unique to the Triassic, whereas others were converged on by later members of Archosauromorpha. One of the most striking examples of this is with Triopticus primus, the early dome-headed form later mimicked by pachycephalosaurid dinosaurs.

Australian recommendations for the management of hepatocellular carcinoma: a consensus statement.

Introduction: Hepatocellular carcinoma (HCC) is a leading cause of cancer deaths both globally and in Australia. Surveillance for HCC in at-risk populations allows diagnosis at an early stage, when potentially curable. However, most Australians diagnosed with HCC die of the cancer or of liver disease.

A pilot study of intrahepatic yttrium-90 microsphere radioembolization in combination with intravenous cisplatin for uveal melanoma liver-only metastases.

Background: Metastatic uveal melanoma is a highly aggressive disease with no standard of care treatment option. A large proportion of patients have liver-only metastatic disease which raises the question if liver-directed therapy can be efficacious in this subpopulation.

Aims: The study aims to evaluate the safety and efficacy of radiosensitizing chemotherapy in combination with yttrium-90 microspheres in patients with uveal melanoma with liver-only metastases.

Prognostic role of alpha-fetoprotein in patients with hepatocellular carcinoma treated with repeat transarterial chemoembolisation.

Background: Repeat transarterial chemoembolisation (rTACE) is often required for hepatocellular carcinoma (HCC) to achieve disease control, however, current practice guidelines regarding treatment allocation vary significantly. This study aims to identify key factors associated with patient survival following rTACE to facilitate treatment allocation and prognostic discussion.

Method: Patients with HCC undergoing rTACE at six Australian tertiary centers from 2009 to 2014 were included.

Mechanisms of soft tissue and protein preservation in Tyrannosaurus rex.

The idea that original soft tissue structures and the native structural proteins comprising them can persist across geological time is controversial, in part because rigorous and testable mechanisms that can occur under natural conditions, resulting in such preservation, have not been well defined. Here, we evaluate two non-enzymatic structural protein crosslinking mechanisms, Fenton chemistry and glycation, for their possible contribution to the preservation of blood vessel structures recovered from the cortical bone of a Tyrannosaurus rex (USNM 555000 [formerly, MOR 555]). We demonstrate the endogeneity of the fossil vessel tissues, as well as the presence of type I collagen in the outermost vessel layers, using imaging, diffraction, spectroscopy, and immunohistochemistry.

Percutaneous transhepatic laser lithotripsy for intrahepatic cholelithiasis: A technical report.

Advances in interventional radiology have seen the adaptation of urological endoscopic laser techniques to treat biliary tract calculi. Percutaneous transhepatic biliary laser lithotripsy provides an effective alternative procedure for the management of intrahepatic or conventionally refractory choledocholithiasis which would otherwise require invasive and high-risk surgical intervention. Several small studies have validated the procedure for management in this subset of patients, with most achieving 100% calculi clearance with minimal complications.
