Radiology insights into Petersen's hernia complication of post Roux-en-Y gastric bypass.

Following gastrojejunostomy in Roux-en-Y gastric bypass (RYGB), the mesentery is susceptible to Petersen's hernia due to a mesenteric gap created between the alimentary limb, transverse mesocolon, and retroperitoneum. Although the Petersen's hernia is a rare complication, it has increased due to the widespread adoption of gastric bypass surgeries for weight management and gastric cancer resections. Computed tomography (CT) is commonly used to evaluate suspected cases.

and Beyond: Impact on Therapeutic Choices Across Cancer.

Background: Identifying patients with gm is crucial to facilitate screening strategies, preventive measures and the usage of targeted therapeutics in their management. This review examines the evidence for the latest predictive and therapeutic approaches in -associated cancers.

Clinical Description: Data supports the use of adjuvant olaparib in patients with gm high-risk HER2-negative breast cancer.

Genomic and transcriptomic profiling of radioresistant prostate and head and neck cancers implicate a BAHD1-dependent modification of DNA damage at the heterochromatin.

Radiotherapy is an integral modality in treating human cancers, but radioresistance remains a clinical challenge due to the involvement of multiple intrinsic cellular and extrinsic tumour microenvironment factors that govern radiosensitivity. To study the intrinsic factors that are associated with cancer radioresistance, we established 4 radioresistant prostate (22Rv1 and DU145) and head and neck cancer (FaDu and HK1) models by irradiating their wild-type parentals to 90 Gy, mimicking the fractionated radiotherapy schema that is often using in the clinic, and performed whole exome and transcriptome sequencing of the radioresistant and wild-type models. Comparative genomic analyses detected the enrichment of mismatch repair mutational signatures (SBS6, 14, 15, 20) across all the cell lines and several non-synonymous single nucleotide variants involved in pro-survival pathways.

Establishing patient partners' roles on research teams: a scoping review.

Background: There are a myriad of ways patient partners can enact their roles on research teams. International guidelines emphasize the need for a collaborative approach to determining these roles to try to improve research impact and positive patient partner experience. The aims of this review were to: (1) describe how patient partners' roles as co-researchers in health research are determined; and (2) identify factors that influence how these decisions are made.

Effect of introduction of a rapid response system and increasing Medical Emergency Team (MET) activity on mortality over a 20-year period in a paediatric specialist hospital.

Background: Rapid Response Systems are hospital-wide patient-focused systems aiming to improve recognition of acute deterioration in patients and trigger a rapid response aimed at preventing potentially avoidable adverse events such as cardiac arrest and death. In 1994, the Royal Children's Hospital in Brisbane, Australia, was one of the first institutions to adopt a paediatric rapid response system (RRS). The purpose of this study was to investigate the impacts of both introduction of a paediatric RRS and increasing RRS activations (MET dose) on hospital mortality.

A simplified geriatric prognostic index to survival in older Asian patients with diffuse large B-Cell lymphoma treated with standard chemo-immunotherapy.

While there are many proposed clinical prediction models for diffuse large B-cell lymphoma, like the International Prognostic Index (IPI), revised IPI and the National Comprehensive Cancer Network IPI, there is no widely used model for older patients. A recent study proposed a Geriatric Prognostic Index (GPI) validated in a Norwegian cohort, using independent predictors involving demographic, biochemical and functional parameters. This study aims to validate the GPI in an Asian cohort and simplify the GPI for ease of clinical application.

Real-world outcomes of diffuse large B-cell lymphoma treated with frontline R-CHOP(-like) regimens in an Asian multi-ethnic population.

Background: Recent breakthrough advances in the treatment of DLBCL, such as the antibody-drug conjugate polatuzumab vedotin, have yielded clinical survival benefit over rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone (R-CHOP) for the first time in 20 years since the advent of the rituximab era. We thus examine the outcomes of standard immunochemotherapy for DLBCL in our multi-ethnic Asian population, so as to determine the real-world clinical need to adopt new therapeutics in this disease entity.

Methods: We conducted a retrospective study involving patients (n = 1071) diagnosed with DLBCL at the National Cancer Centre Singapore from 2010 to 2022, and treated with first-line rituximab-based regimens.

Real-World Outcomes for Localised Gastro-Oesophageal Adenocarcinoma Cancer Treated with Perioperative FLOT and Prophylactic GCSF Support in a Single Asian Centre.

Background: Perioperative FLOT (5-fluorouracil, oxaliplatin and docetaxel) is a standard of care for patients with locally advanced gastro-oesophageal adenocarcinoma (GEA) in Western guidelines, but its use is limited in Asian patients. We report outcomes from a single Asian centre of perioperative FLOT with concomitant granulocyte colony-stimulating factor (GCSF) prophylaxis.

Methods: A retrospective analysis of all 56 stage II to III GEA patients treated with perioperative FLOT at the National Cancer Centre Singapore between June 2017 and February 2024 was performed.

Impact of mild hypercapnia in critically ill patients with metabolic acidosis.

Purpose: Clinical trials focusing on critically ill patients with metabolic acidosis, a common exclusion criterion is the presence of a PaCO > 45 mmHg. The aim of this study was to assess the impact of mild hypercapnia on patient characteristics, severity, and clinical outcomes in critically ill patients with metabolic acidosis.

Material And Methods: Multicentre, retrospective, observational study conducted in 12 intensive care units (ICUs) in Queensland, Australia.

Credentialling in Australia for infection prevention and control: Philosophy, principles and practice.

Infection prevention and control programs are vital to ensuring the health and wellbeing of healthcare consumers and staff. Infection control professionals who lead these programs are uniquely positioned with the knowledge, skills and attributes to direct effective infection control practices and policies within their healthcare setting. As with many specialisations, these individuals may choose to undertake a credentialling process, where their expertise and competence are evaluated and formally recognised by a professional body.

Lost in Transition: Insights from a Retrospective Chart Audit on Nutrition Care Practices for Older Australians with Malnutrition Transitioning from Hospital to Home.

Care transitions from hospital to home for older adults with malnutrition present a period of elevated risk; however, minimal data exist describing the existing practice. This study aimed to describe the transition of nutrition care processes provided to older adults in a public tertiary hospital in Australia. A retrospective chart audit conducted between July and October 2022 included older (≥65 years), malnourished adults discharged to independent living.

Kartagener syndrome with pectus excavatum and upper lobar bronchiectasis.

Primary Ciliary Dyskinesia (PCD) is a rare autosomal recessive disorder caused by impaired ciliary function. The incidence of PCD is 1 in 20,000 births. Kartagener's syndrome (KS), a subtype of PCD, is distinguished by the presence of situs inversus.

Evaluation of an interactive education workshop on hospital pharmacists' ethical reasoning: an observational study.

Background: Pharmacists are often faced with scenarios in practice that require application of ethical reasoning and decision-making skills. There is limited research on the ethical decision-making processes of hospital pharmacists. Pharmacists who are compassionate and put the interests of their patients first are thought to positively impact on patient care, but there are often complex health-care system pressures in the hospital setting that cause pharmacists to behave in ways that may conflict with professional values and behaviours.

TWEAK/Fn14 signalling driven super-enhancer reprogramming promotes pro-metastatic metabolic rewiring in triple-negative breast cancer.

Triple Negative Breast Cancer (TNBC) is the most aggressive breast cancer subtype suffering from limited targeted treatment options. Following recent reports correlating Fibroblast growth factor-inducible 14 (Fn14) receptor overexpression in Estrogen Receptor (ER)-negative breast cancers with metastatic events, we show that Fn14 is specifically overexpressed in TNBC patients and associated with poor survival. We demonstrate that constitutive Fn14 signalling rewires the transcriptomic and epigenomic landscape of TNBC, leading to enhanced tumour growth and metastasis.

Diagnosis of an unusual orbital abscess following sub-Tenon's steroid injection: a case report.

Orbital abscesses are caused by infection within or near the orbit and show obvious signs of pain, proptosis and raised inflammatory markers. Diagnosis is based on clinical features and radiological imaging, and requires early antibiotics and often surgical drainage to save vision. Sub-Tenon's injections of triamcinolone acetonide (TA) have caused localized infections in previous reports, which have responded to therapeutic interventions.

A Preparatory Virtual Reality Experience Reduces Anxiety before Surgery in Gynecologic Oncology Patients: A Randomized Controlled Trial.

Perioperative anxiety is common among patients undergoing surgery, potentially leading to negative outcomes. Immersive virtual reality (VR) has shown promise in reducing anxiety in various clinical settings. This study aimed to evaluate the effectiveness of VR in reducing perioperative anxiety in patients undergoing gynecological oncology surgery and was conducted as a single-center, double-arm, single-blinded randomized controlled trial at the Gold Coast University Hospital, Queensland, Australia.
