This research investigates the biomechanical effects of a novel ceramic implant for the treatment of canine cranial cruciate ligament rupture (CCLR) based on the tibial tuberosity advancement (TTA) method using finite element analysis (FEA). A 3D FEA of the tibiofemoral joint simulating the applied forces (44.5% of body weight) during the mid-stance phase (joint angle 135°) of the dog's stride was performed.

Purpose: The purpose of this study was to assess the effect of training with a personal, portable laparoscopic endo-trainer (PLET) on residents' laparoscopic skills.

Methods: The study took place at a tertiary-care academic university hospital in Switzerland. All participants were randomized to either a home- or hospital-based PLET training group, and surgical skill performance was assessed using five laparoscopic exercises.

Article Synopsis
  • - Teratomas are rare germ cell tumors usually found in children, and a unique case of retroperitoneal papillary thyroid carcinoma in an adult woman is discussed here.
  • - A 41-year-old woman experienced intermittent abdominal pain, leading to the discovery of a retroperitoneal mass that turned out to be papillary thyroid carcinoma after surgical removal.
  • - Diagnosing primary retroperitoneal teratomas can be challenging due to vague symptoms and limited imaging findings; surgery is the main treatment, but decisions on further treatments like total thyroidectomy and radioiodine therapy remain debated.

Objective: Telemedicine is becoming an increasingly feasible option for patients with chronic diseases due to its convenience, cost-effectiveness and ease of access. While there are certain limitations, the benefits can be appreciated by those seeking repetitive care. The perception of telemedicine as an alternative to recurrent, in-person appointments for patients with obesity in structured bariatric programmes is still unclear.

Article Synopsis
  • The study focuses on comparing the long-term quality of life (QoL) outcomes between two surgical methods for esophageal cancer: open Ivor Lewis esophagectomy (Open-E) and a hybrid approach (hRob-E) that combines laparotomy and robot-assisted surgery.
  • Patients were evaluated 36 to 40 months post-surgery using specific QoL questionnaires, revealing that both groups had similar emotional and cognitive functioning, but noticeable differences in physical functioning and pain.
  • Results suggest that while global health status remains stable post-surgery, hRob-E patients may experience better physical functioning and less pain compared to those who underwent Open-E, indicating potential advantages of the hybrid approach.

Article Synopsis
  • Medical students need to learn how to cope with failure in clinical training, as it's an inevitable part of becoming a physician, but curricula rarely address this topic effectively.
  • A workshop was conducted by surgical consultants and a life coach, incorporating various teaching methods, aiming to help students identify, communicate about, and reflect on failures while developing coping strategies.
  • Participants rated the workshop positively, feeling more prepared to handle future challenges and appreciating the opportunity to discuss failure in a safe environment, which could help reduce stigma in medical education.

Purpose: In the long term, laparoscopic sleeve gastrectomy (SG) may be associated with insufficient weight loss (IWL), gastroesophageal reflux disease (GERD), and persistence or relapse of associated medical problems. This study's objective is to present mid-term results regarding weight loss (WL), evolution of associated medical problems, and reoperation rate of patients who underwent a conversion after SG.

Methods: Retrospective single-center analysis of patients with a minimal follow-up of 2 years after conversion.

Introduction: Attendings allow trainee failure when perceived educational benefits outweigh potential patient harm. This strategy has not been explored in pediatrics, where it may be shaped by unique factors. Our objectives were to understand if, when, and how pediatric hospitalists allow trainees to fail during clinical encounters.

Virtual surgical planning is the process of planning and rehearsing a surgical procedure completely within the virtual environment on computer models. Virtual surgical planning and 3D printing is gaining popularity in veterinary oromaxillofacial surgery and are viable tools for the most basic to the most complex cases. These techniques can provide the surgeon with improved visualization and, thus, understanding of the patients' 3D anatomy.

Introduction: Clinical supervisors allow trainees to fail during clinical situations when trainee learning outweighs concerns for patient safety. Trainees perceive failure as both educationally valuable and emotionally draining; however, the nuance of supervised failures has not been researched from the trainee perspective. This study explored trainees' awareness and their experience of failure and allowed failure to understand those events in-depth.

Introduction: The study was conducted to explore the perceptions of patients from a bariatric program who have undergone or will undergo bariatric surgery during the ongoing COVID-19 pandemic, specifically as related to their struggles with health issues and their psychological well-being.

Materials And Methods: We conducted semi-structured, in-depth interviews with nineteen pre- or post-bariatric patients to generate data on their perceptions of COVID-19. Consistent with the methods of constructivist grounded theory, we collected and analyzed data iteratively through a constant comparative process for data coding and develop themes in the transcripts.
