Hypoalbuminemia is a risk factor for mortality in patients with end-stage liver disease (ESLD) and in those undergoing orthotopic liver transplantation (OLT), since it represents a biomarker of post-operative delayed functional recovery of the graft. Despite albumin infusion during and after OLT is frequently adopted in recipients with hypoalbuminemia, it remains unclear whether this procedure could improve post OLT clinical outcomes. Observational studies indicated that treatment with albumin after OLT might be beneficial in reducing ascites and acute kidney injury (AKI) development.

Pancreatic cancer has an increasing incidence and prevalence trend. Its prognosis is negatively affected by poor/altered nutritional status. Therefore, nutritional interventions play a critical/pivotal role at any stage.

Introduction: There is an evidence-practice gap in the optimal timing and volume of intravenous fluid as well as vasopressor administration in managing patients with sepsis. This study aimed to explore current hemodynamic resuscitation practice in emergency department (ED) for patients with sepsis and hypotension.

Methods: This is a sub-analysis of the prospective multicentre ARISE FLUIDS observational study, which was conducted in 70 EDs across Australia and New Zealand.

Article Synopsis
  • This study compares injury patterns in fatal falls from heights versus those of pedestrians struck by cars, aiming to improve diagnosis in ambiguous cases of such incidents.
  • Analyzing 232 forensic reports from 2012 to 2023, the study found that falls from heights were linked to significantly higher rates of bilateral lung and liver injuries, as well as skull fractures.
  • Meanwhile, pedestrians showed greater instances of leg fractures and external injuries, with a notable threshold for "Total Injured Skin Area" suggesting that larger injuries may indicate a road traffic fatality.

Introduction: In Australia, short-acting β-agonists (SABA) are available both over the counter (OTC) and on prescription. This ease of access may impact SABA use in the Australian population. Our aim was to assess patterns and outcome associations of prescribed, acquired OTC and reported use of SABA by Australians with asthma.

Article Synopsis
  • Combining ICS (a type of medicine) with long-acting bronchodilators (LABD) helps people with COPD have fewer flare-ups than just using LABD alone.
  • The study compared the risk of getting pneumonia between patients using ICS with a special medicine called ef-BDP and those only using LABD.
  • Results showed that using ef-BDP/LABD didn't increase the chance of getting pneumonia compared to LABD alone, which is a good sign for people with COPD.

Aim: The International Severe Asthma Registry (ISAR; http://isaregistries.org/) uses standardised variables to enable multi-country and adequately powered research in severe asthma. This study aims to look at the data countries within ISAR and non-ISAR countries reported collecting that enable global research that support individual country interests.

Familicide, an extreme form of domestic violence where one family member kills another, is a complex criminological issue. We analyzed autopsy files from the Institute of Legal Medicine, University of Rome Tor Vergata (1995-2022), to understand familicide better. The study focused on victim profiles, offender characteristics, and case dynamics.

Background: Compared to other types of abdominal protrusions, Spigelian hernias are not very common. In prosthetic repair of abdominal protrusions, mesh fixation and defect overlap are an open issue, as they are a source of complications. A newly developed tentacle-shaped mesh has been used to ensure a fixation-free repair with a broader defect overlap in the repair of abdominal hernias.

Purpose: Programmed cell death protein-1 (PD-1) receptor and ligand interactions are the target of immunotherapies for more than 20 cancer types. Biomarkers that predict response to immunotherapy are microsatellite instability, tumor mutational burden, and programmed death ligand-1 (PD-L1) immunohistochemistry. Structural variations (SVs) in PD-L1 () and PD-L2 () have been observed in cancer, but the comprehensive landscape is unknown.

Aims: The therapeutic properties of anti-hypertensive medications that extend beyond blood pressure lowering have started to become important clinical targets in recent years. This study aimed to assess the cardioprotective effects of perindopril in attenuating complications associated with metabolic syndrome in diet induced obese rats.

Main Methods: Male Wistar-Kyoto (WKY) rats aged 16 weeks were fed either standard rat chow (SC) or given a high-fat-high-carbohydrate (HFHC) diet for 20 weeks.

Endometriosis is a disease affecting approximately 10% of women of fertile age. A particular presentation is deep infiltrating endometriosis of the rectosigmoid colon with symptoms that can mimic an intestinal obstruction or neoplasm. We report the case of a 39-year-old woman with pelvic pain during the menstrual cycle and significant anemia who presented an ectopic endometrial tissue in correspondence of the rectum.

"Overkill" is characterized by the finding of excessive wounds on the victim's body. Despite the large use of this term, it does not have a definition in the literature yet. Our study aimed to analyze the information related to the dynamics of overkill cases, collecting objective variables, and producing a profile of the players involved in this type of homicides.

Introduction: Bowel perforation is a relatively rare presentation of abdominal tuberculosis, whose diagnosis is challenging but fundamental to minimize morbidity and mortality. Laparoscopy is considered an effective modality for diagnosis, but its role in surgical treatment is still not established. We reported the first worldwide case of totally laparoscopic treatment of intestinal tuberculosis complicated with bowel perforation.

Introduction: Asthma poses a significant burden for the Australian population. Understanding severe exacerbation rates, and steroid-related burden for adults diagnosed with asthma stands to offer insights into how this could be reduced.

Methods: Electronic medical records (EMR) and questionnaires from the Optimum Patient Care Research Database Australia (OPCRDA) were utilised retrospectively.

Introduction: Klippel-Trenaunay syndrome is an uncommon congenital disease also called angio-osteodystrophy syndrome for its typical disorders characterized by abnormal growth of the soft tissues and bones and vascular malformations.

Case Report: In this report, we present a rare case of a 46-year-old nulliparous woman with Klippel-Trenaunay syndrome. She suffered from an abnormal uterine bleeding accompanied by severe anemia with need for multiple blood transfusions.

Background: Inhaled corticosteroids (ICS) afford therapeutic benefits in some COPD patients, but their widespread use is cautioned due to an increased risk of developing pneumonia. Subclass variations exist, and the risk profile differs for individual ICS. Formulation particle size has been identified as a potential effect modifier.

Background: Full-fixed appliance orthodontic treatment (commonly called braces) increases plaque accumulation and the risk of gingivitis and periodontitis. However, little consensus exists on changes to subgingival microbiota and specific periodontopathogens during treatment with braces. Prior studies have been hampered by selection biases due to dependence on culture conditions, candidate-based PCR and shallow sequencing methods.

Objective: It is widely accepted that the microbiota is critical for human well-being; however, the origin of microbiota in the newborn is not well understood. In this study, we hypothesized that within a maternal-twin dyad (MTD) the meconium microbiome will be similar to the placenta microbiome and the meconium microbiome of within MTD will be similar to one another.

Methods: Prospectively, meconium (proxy for fetal gut), placenta and maternal buccal, skin, vaginal, stool samples were collected from a cohort of MTDs at time of delivery hospitalization.

The cumulative effect of mild traumatic brain injuries (mTBI) can result in chronic neurological damage, however the molecular mechanisms underpinning this detriment require further investigation. A closed head weight drop model that replicates the biomechanics and head acceleration forces of human mTBI was used to provide an exploration of the acute and chronic outcomes following single and repeated impacts. Adult male C57BL/6J mice were randomly assigned into one of four impact groups (control; one, five and 15 impacts) which were delivered over 23 days.
