Background: The presence of insulin resistance (IR) in patients with type 1 diabetes mellitus (T1DM) is a significant indicator of all chronic diabetic complications, independent of other risk factors. The estimated glucose disposal rate (eGDR) is a practical method that can be easily used in daily practice to determine IR. This study aimed to determine the cutoff values for two eGDR methods and compare their diagnostic value for determining IR in adult T1DM patients with metabolic syndrome (MetS). Methods: This cross-sectional study was performed on 184 adults admitted to the endocrinology outpatient clinic diagnosed with T1DM...

BACKGROUND: General obesity is a well-established risk factor for gallstone disease (GSD), but whether central obesity contributes additional independent risk remains controversial. We aimed to comprehensively clarify the effect of body fat distribution on GSD. METHODS: We first investigated the observational association of central adiposity, characterized by waist-to-hip ratio (WHR), with GSD risk using data from UK Biobank (N=472,050). We then explored the genetic relationship using summary statistics from the largest genome-wide association study of GSD ( ncase =43,639, ncontrol =506,798) as well as WHR, with and without adjusting for body mass index (BMI) (WHR: n =697,734; WHRadj BMI: n =694,649)...

BACKGROUND: Increasingly hip replacements at young age exposes the patient to an increased risk of failure of the implant over the years. In case of failure, revision specific stems were designed to overcome bone loss. Modularity of these devices is an important resource for the surgeon as they allow the new implant to be better adapted to the patient's anatomy. The purpose of this systematic review is to provide data about the outcome at long-term follow-up (>8 years) of hip modular revision femoral stems...

OBJECTIVE: Intramedullary nails are commonly used for the purposes of internal fixation in the repair of tubular bone fractures, allowing for optimal fixation while minimizing intraoperative bleeding, surgical incision size, and associated stress. These nails are thus often utilized to repair hip and peripheral fractures, femur fractures, tibial fractures, humerus fractures, and clavicle fractures. Recent life expectancy increases, rising economic standards, and technological innovations have led to the application of a wider range of materials and techniques in the context of orthopedic device production, further expanding the clinical indications for intramedullary nailing...
