Filter by:Sarcopenia is defined by the reduction in skeletal muscle mass and physical performance. It results in a decrease in muscle strength, overall physical activity, walking and the development of balance disorders and falls. It is one of the natural consequences of aging and contributes to frailty and the appearance of geriatric syndrome (s) (Chandapasirt et al, 2015; Cruz-Jentoft et al, 2010). Its prevalence in patients with Head & Neck cancer is 39% (Hua et al, 2020) and is associated with an increase in postoperative complications (Achim et al, 2017; Bril et al, 2019), with greater toxicity of chemotherapy. (Wendrich et al, 2017) and reduced overall survival (Hua et al, 2020). It is measured by CT scan (assessment of muscle volume with respect to L3 using IMAGE J software) (Teigen et al, 2018) and by clinical tests (performance tests) (Swartz et al, 2016, Cruz-Jentoft et al, 2010). Several studies have shown a possible assessment of sarcopenia by measuring skeletal muscle mass with regard to C3 (Ufuk et al, 2019; Swartz et al, 2016). This trial aims to evaluate the prevalence of sarcopenia in head and neck cancer evaluated by CT at C3.
To present the first admission chest computed tomography (CT) findings of patients followed up with a diagnosis of COVID-19, and to compare the two classification systems by evaluating these findings according to the BSTI and RSNA guidelines.
The QUICK study main aim is to assess the predictive value at Day 1, of a model built on lung ultrasound (LUS) and clinical data, both recorded at hospital admission of COVID-19 patients.
Back pain costs the U.S. over $100 billion annually, and much of this spending is wasteful due to the overuse of advanced diagnostic imaging. Despite prominent clinical guidelines and the nationally recognized Choosing Wisely campaign discouraging use of costly and low value imaging, magnetic resonance imaging (MRI) and computed tomography (CT) studies remain frequently overused. Real-time electronic clinical decision support (CDS) at the point of care has been increasingly emphasized as an important strategy to improve the value of back pain management; however, studies suggest that CDS at best only modestly influences practice patterns. The aim is to implement a behavioral economic-based intervention in the ED to promote the use of CDS system.
Early intervention attempts to shorten protracted delayed union (DU) or prevent non-union (NU) fractures are hampered by lack of validated quantitative assessment tools for bone fracture healing during normal and delayed healing processes. In actual practice, sequential X-rays usually follow a pre-determined time interval in patients with fractures.They constitute the best available state of the art used by surgeons to assess the fracture healing course. In an attempt to improve between raters reliability of radiographic assessment of healing, studies have explored a novel radiographic assessment for tibial shaft fractures, the Radiographic Union Scale for Tibial Fractures (RUST). The RUST assesses the presence of bridging callus and a fracture line on each of four cortices (seen on anterior-posterior and lateral views). This callus based scoring system has been since extended to other bones than the tibia in a retrospective case series. It has been renamed modified radiological union score (mRUS) and has shown potential value in bone healing measurement. Based on an initial retrospective study in nail-treated fractures, the first objective of the present investigation is to prospectively validate mRUS as a tool to identify patients at increased risk of DU and NU within the first 75-110 days after fracture occurrence. This prospective validation will be performed on a retrospective cohort of patients having sustained long bone fractures, including both upper and lower extremities. A further objective of the present investigation is to apply the scoring system to tomographic imaging in case of nail/plate treated fractures, deriving a tomographic union score (TUS) and first assess its potential value in bone healing for fractures treated by nails/plates.
