Simulating soft tissue deformation in real-time has become increasingly important in order to provide a realistic virtual environment for training surgical skills. Several methods have been proposed with the aim of rendering in real-time the mechanical and physiological behaviour of human organs, one of the most popular being Finite Element Method (FEM). In this paper we present a new approach to the solution of the FEM problem introducing the concept of parent and child mesh within the development of a hierarchical FEM. The online selection of the child mesh is presented with the purpose to adapt the mesh hierarchy in real-time. This permits further refinement of the child mesh increasing the detail of the deformation without slowing down the simulation and giving the possibility of integrating force feedback. The results presented demonstrate the application of our proposed framework using a desktop virtual reality (VR) system that incorporates stereo vision with integrated haptics co-location via a desktop Phantom force feedback device.

Introduction: Young adulthood is well documented as being a particularly challenging area of type 1 diabetes (T1D) healthcare. Many young adults with T1D (YAT1D) are distracted from effective disease self-management; T1D healthcare service engagement can be problematic and inconsistent, and high rates of unplanned healthcare contacts prevail. Video conferencing use can facilitate services to be flexible and responsive.

Food neophobia and pickiness are the resistance or refusal to eat and/or avoid trying new foods due to a strong reaction of fear towards the food or an entire group of foods. This systematic review aims to assess evidence on the risk factors and effects of food neophobia and picky eating in children and adolescents, giving elements to avoid the lack of some foods that can cause nutritional deficiencies, leading to future pathologies when they are adults. A systematic literature search was performed in Medlars Online International Literature (MEDLINE) via Pubmed and EBSCOhost, LILACS and IBECS via Virtual Health Library (VHL), Scopus, and Google Scholar.

Department of Surgery, Institute of Clinical Sciences, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden.
Purpose: Surgery for groin hernia is one of the most common operations in the world. Therefore, research concerning the outcomes of groin hernia surgery is extremely important both for the individual patient as well as for those providing the healthcare funding. The aim of this study is to evaluate the outcomes of hernia surgery in Sweden over a 30 year time period, from 1992 to 2021.

Purpose Of Review: Whether low birth weight (LBW) and preterm delivery (PD) are associated with the risk of developing celiac disease (CD) in children remains unclear. This systematic review and meta-analysis aimed to evaluate the association between LBW and PD with CD development in children.
Recent Findings: We searched PubMed, Embase, Scopus, Web of Science, and Google Scholar databases based on the Mesh terms to find observational studies that investigated the association of LBW and PD with CD development in children up to July 18, 2024.
Pelvic Organ Prolapse Repair Using Robotic-Assisted Sacral Hysterocolpopexy vs Vaginal Surgery with the Uphold™ System: 1-Year Clinical Outcomes.
Int Urogynecol J
January 2025
Department of Clinical Sciences, Division of Obstetrics and Gynecology, Karolinska Institutet Danderyd Hospital, SE- 182 88, Stockholm, Sweden.
Introduction And Hypothesis: The aim of the study was to compare clinical outcomes when using robotic-assisted sacral hysterocolpopexy (RASC) and vaginal surgery using the Uphold™ Vaginal Support System mesh for pelvic organ prolapse repair.
Methods: This was a nonrandomized, prospective, multicenter study in which 72 women underwent RASC, and 73 Uphold™ surgery, for apical prolapse (POP-Q C ≥ stage II). Anatomical outcomes were assessed using the Pelvic Organ Prolapse Quantification (POP-Q) system.
