Human factors application for healthcare teams in low- and medium-income countries (LMIC) to help improve patient safety and performance.

Mistakes will always happen whether at work or in our personal lives. We can never completely eliminate error, but learning and disseminating lessons from these mistakes to others is essential. Human factors application for colleagues in healthcare, particularly in low- and medium-income countries (LMIC) can greatly improve patient safety and aid better team working and staff morale.

Temporomandibular joint anatomy: Ultrasonographic appearances and sexual dimorphism.

Introduction: Temporomandibular joint (TMJ) dysfunction is common, with a greater prevalence in females. While magnetic resonance imaging (MRI) is commonly used for clinical investigation, ultrasonography represents a potential alternative in some clinical scenarios. We designed a protocol for ultrasonographic evaluation of the TMJ and assessed its reliability.

Coronavirus pandemic: applying a whole-of-society model for the whole-of-the world.

During a pandemic, a national government is often considered solely responsible for dealing with the outbreak with local-based policies. A whole-of-society approach to a pandemic is evidence-based and used successfully in countries with a history of pandemic infections. This collaborative approach assumes that no single entity has the capacity to successfully manage the dynamic, complex problems that arise in a pandemic environment.

Hypertension in a teenager: a family affair.

We present a young, lean, female patient following surveillance by the general practitioner for abnormally high blood pressure readings. Her grandmother died at a young age because of hypertension which shows her family has significant history for hypertension. Her symptoms and signs included feeling hot and nauseous following exercise, sweating and palpitations.

Beyond weight loss: evaluating the multiple benefits of bariatric surgery after Roux-en-Y gastric bypass and adjustable gastric band.

Background: Despite the evidence for benefits beyond weight loss following bariatric surgery, assessments of surgical outcomes are often limited to changes in weight and remission of type 2 diabetes mellitus. To address this shortfall in assessment, the King's Obesity Staging System was developed. This system evaluates the individual in severity stages of physical, psychological, socio-economic and functional disease.

68-Year-Old Man with PR Bleed.

A 68-year-old man is referred to the colorectal clinic by his GP. He has lost 10 kg in weight over the last two months. He also noticed that his bowel motions have been loose and sometimes contain blood.

An 81 Year Old with Back Pain.

You see an 81-year-old man in the emergency department. He has been troubled by abdominal and back pain that has been worsening over the last two days. He has smoked 20 cigarettes a day for the last 60 years.

Deliberate practice on a virtual reality laparoscopic simulator enhances the quality of surgical technical skills.

Introduction: Virtual reality (VR) simulation provides unique training opportunities. This study evaluates whether the deliberate practice (DP) can be successfully applied to simulated laparoscopic cholecystectomy (LC) for enhancement of the quality of surgical skills.

Methods: Twenty-six inexperienced surgeons underwent a training program for LC on a VR simulator.

SERCA2a gene transfer decreases sarcoplasmic reticulum calcium leak and reduces ventricular arrhythmias in a model of chronic heart failure.

Background: Sarcoplasmic reticulum calcium ATPase 2a (SERCA2a) gene therapy improves mechanical function in heart failure and is under evaluation in a clinical trial. A critical question is whether SERCA2a gene therapy predisposes to increased sarcoplasmic reticulum calcium (SR Ca(2+)) leak, cellular triggered activity, and ventricular arrhythmias in the failing heart.

Methods And Results: We studied the influence of SERCA2a gene therapy on ventricular arrhythmogenesis in a rat chronic heart failure model.
