Factors influencing the cost-effectiveness of radiofrequency ablation for Barrett's esophagus with low-grade dysplasia in Australia.

Endoscopic eradication therapy using radiofrequency ablation (RFA) is considered an acceptable alternative to surveillance monitoring for Barrett's esophagus with low-grade dysplasia (LGD). This study aimed to estimate whether RFA for LGD is cost-effective and to determine which factors influence cost-effectiveness. A Markov model was developed to estimate the incremental cost per quality-adjusted life year (QALY) gained for RFA compared with endoscopic surveillance.

Targeted Muscle Reinnervation Compared to Standard Peripheral Nerve Management Following Amputation: A Systematic Review and Meta-Analysis.

Background: Chronic pain remains a significant challenge for individuals following limb amputation, with incidence of painful neuromas, phantom limb pain (PLP), and residual limb pain (RLP). Targeted muscle reinnervation (TMR) is a surgical technique designed to restore motor control information lost during amputation by redirecting residual nerves to new muscle targets. This systematic review and meta-analysis aims to compare patient-reported and functional outcomes following amputation with either TMR or standard neurological treatment (SNT).

A junior doctor led near-peer acute ENT/head and neck surgery workshop for medical students.

Background: Near-peer teaching (NPT) involves teaching by peers who are at a close, but not the same, level of training. This study investigated whether a novel surgical NPT workshop, designed and delivered by junior doctors using simulation models for acute otolaryngology conditions, improved the knowledge and confidence level of senior medical students.

Methods: A one-day NPT workshop was held for medical students in their third year of a four-year postgraduate medical degree at the University of Notre Dame, Sydney, Australia.

Socioeconomic status and the effect of prolonged pandemic confinement on anthropometric and glycaemic outcomes in adults with type 2 diabetes mellitus.

Aim: This systematic review and meta-analysis aimed to investigate the impact of COVID19 lockdown on the anthropometric and glycaemic outcomes of adults with type 2 diabetes mellitus (T2DM) and assess whether socioeconomic status (SES) was relevant to these changes.

Methods: A search of three databases was conducted. Meta-analyses using random effects models were undertaken to combine anthropometric and glycaemic measures pre- and post-confinement.

How to effectively use and interpret the barium swallow: Current role in esophageal dysphagia.

Background: The barium swallow is a commonly performed investigation, though recent decades have seen major advances in other esophageal diagnostic modalities.

Purpose: The purpose of this review is to clarify the rationale for components of the barium swallow protocol, provide guidance on interpretation of findings, and describe the current role of the barium swallow in the diagnostic paradigm for esophageal dysphagia in relation to other esophageal investigations. The barium swallow protocol, interpretation, and reporting terminology are subjective and non-standardized.

Reduced number of admissions with acute appendicitis but not severe acute appendicitis at two Sydney hospitals during the first COVID-19 lockdown period.

Background: This study investigated whether there was a change in acute appendicitis, appendicectomy admissions or disease severity during the 2020 lockdown period in NSW.

Methods: A retrospective before-and-after study was undertaken of patients admitted to two Sydney hospitals (St. Vincent's and Liverpool Hospitals) who had appendicectomy for presumed acute appendicitis and patients who had confirmed appendicitis but did not undergo surgery.

Clinical pathways and outcomes of patients with Barrett's esophagus in tertiary care settings: a prospective longitudinal cohort study in Australia, 2008-2016.

Background: Clinical services for Barrett's esophagus have been rising worldwide including Australia, but little is known of the long-term outcomes of such patients. Retrospective studies using data at baseline are prone to both selection and misclassification bias. We investigated the clinical characteristics and outcomes of Barrett's esophagus patients in a prospective cohort.

Cancer incidence in Madras Presidency in 1892-1901: William Niblock's commentary of 1902.

William J. Niblock (WJN), an Assistant Surgeon at the Madras General Hospital (MGH), published a paper 'Cancer in India' (2 pages of text and 3 pages of tables) in the Indian Medical Gazette in 1902. He appears to have been a popular surgeon in Madras who surgically treated mouth cancers, testicular filariasis, and calcareous stones in the liver, gall bladder, and kidney.

First aid improves clinical outcomes in burn injuries: Evidence from a cohort study of 4918 patients.

Background: Animal studies indicate treating burn injuries with running water (first aid) for 20min up to 3h post-burn reduces healing time and scarring. There is a lack of human data to support such a recommendation. The purpose of this cohort study was to assess the effect of first aid on clinical outcomes.

Evaluation of Serum Glycoprotein Biomarker Candidates for Detection of Esophageal Adenocarcinoma and Surveillance of Barrett's Esophagus.

Esophageal adenocarcinoma (EAC) is thought to develop from asymptomatic Barrett's esophagus (BE) with a low annual rate of conversion. Current endoscopy surveillance of BE patients is probably not cost-effective. Previously, we discovered serum glycoprotein biomarker candidates which could discriminate BE patients from EAC.

Novel Aberrations Uncovered in Barrett's Esophagus and Esophageal Adenocarcinoma Using Whole Transcriptome Sequencing.

Esophageal adenocarcinoma (EAC) has one of the fastest increases in incidence of any cancer, along with poor five-year survival rates. Barrett's esophagus (BE) is the main risk factor for EAC; however, the mechanisms driving EAC development remain poorly understood. Here, transcriptomic profiling was performed using RNA-sequencing (RNA-seq) on premalignant and malignant Barrett's tissues to better understand this disease.

Early metal stent insertion fails to prevent stricturing after single-stage complete Barrett's excision for high-grade dysplasia and early cancer.

Background: Barrett's esophagus with high-grade dysplasia (HGD) or intramucosal adenocarcinoma (IMC) can be effectively treated by single-session EMR, resulting in complete Barrett's excision (CBE). CBE provides accurate histology for staging and clinical confirmation of neoplasia eradication but is limited by a high risk of esophageal stricture formation.

Objective: To evaluate the effectiveness of prophylactic temporary esophageal stenting to prevent post-CBE stricture formation.

Robot-assisted gastrectomy and oesophagectomy for cancer.

Background: Robot-assisted surgery is a technically feasible alternative to open and laparoscopic surgery, which is being more frequently used in general surgery. We undertook this review to investigate whether robotic assistance provides a significant benefit for oesophagogastric cancer surgery.

Methods: Electronic databases were searched for original English-language publications for robotic-assisted gastrectomy and oesophagectomy between January 1990 and October 2013.
