Background: The utility of diagnostic genetic testing in cardiomyopathy has grown significantly, due to the discovery of novel genes and greater awareness among healthcare professionals. However, a substantial proportion of cases (around 50%) yield no causative genetic variants or have variants of unknown significance (VUS), limiting their use in clinical management and familial screening. The increase in data quantity and quality in reference databases, coupled with variant interpretation guidelines, allows for periodic reanalysis of VUS, potentially reducing diagnostic gaps.

Article Synopsis
  • Obesity increases the risk of complications after abdominal hernia repair, and GLP-1 receptor agonists are being explored as weight loss aids to help patients qualify for surgery.* -
  • In a study reviewing obese patients undergoing elective hernia repair, those using GLP-1 therapy alongside lifestyle changes achieved comparable weight loss results to those using lifestyle changes alone, despite having different types of hernias.* -
  • The study found that patients using GLP-1 had a significantly shorter time from starting the medication to their surgery compared to controls, although both groups had similar outcomes in terms of weight loss and complication rates.*

Many patients infected with the SARS-CoV-2 virus (COVID-19) continue to experience symptoms for weeks to years as sequelae of the initial infection, referred to as "Long COVID". Although many studies have described the incidence and symptomatology of Long COVID, there are little data reporting the potential burden of Long COVID on surgical departments. A previously constructed database of survey respondents who tested positive for COVID-19 was queried, identifying patients reporting experiencing symptoms consistent with Long COVID.

This paper describes a pluralistic framework to inform transformative change across community and healthcare domains to optimize the mental health of older adults in support of healthy ageing. An extensive review and analysis of the literature informed the creation of a framework that contextualizes the priority areas of the WHO Decade of Health Ageing (ageism, age-friendly environments, long-term care, and integrated care) with respect to older adult mental health. The framework additionally identifies barriers, facilitators, and strategies for action at macro (social/system), meso (services/supports), and micro (older adults) levels of influence.

Establishing intervention effectiveness is an important component of a broader knowledge translation (KT) process. However, mobilizing the implementation of these interventions into practice is perhaps the most important aspect of the KT cycle. The purpose of the current study was to conduct an umbrella review to (a) identify promising interventions for SI&L in older adults, (b) interpret (translate) the findings to inform clinical knowledge and practice interventions in different settings and contexts, and (c) highlight research gaps that may hinder the uptake of these interventions in practice.

Background: The field of robotic-assisted surgery is rapidly growing as many robotic surgical devices are in development and about to enter the market. Currently, there is no universally accepted language for labeling the different robotic systems. To facilitate this communication, we created what is, to our knowledge, the first classification of surgical robotic technologies that organizes and classifies surgical robots used for endoscopy, laparoscopy and thoracoscopy.

Purpose: Sleeve gastrectomy (SG) is a commonly performed metabolic-bariatric surgery, but its effectiveness is variable and difficult to predict. Our study aimed to compare control of eating (CoE) attributes pre- and post-SG depending on the achievement of optimal weight loss target at 1 year post-SG.

Materials And Methods: A prospective longitudinal cohort study using the CoE Questionnaire, pre-SG, and postoperatively at 3, 6, and 12 months was conducted.

Aim: SSI is one of the most prevalent healthcare-associated infections and is associated with extended hospital stays, increased need for reoperation and higher hospital readmission rates. Implementing systematic SSI surveillance can reduce these adverse outcomes. Implementing a surveillance system into a hospital is a complex intervention requiring that staff involved in a patient's perioperative journey have the knowledge of SSI prevention, the data required for surveillance, an understanding of how data informs quality improvement initiatives and their role in surveillance.
