The Effect of Frontal Deformity at the Ankle Joint on Total Ankle Arthroplasty Revision Rate.

The presence of severe coronal plane deformity in the ankle joint is widely recognized as challenging to correct by total ankle joint arthroplasty alone, necessitating additional rearfoot fusion. The primary aim of this retrospective study was to investigate the potential associations between the presence or severity of coronal tibiotalar deformities and adverse outcomes after isolated total ankle arthroplasty, such as revisions and complications. The secondary aim was to analyze the potential associations between comorbidities, demographics, and implant types, and adverse outcomes.

Optineurin regulates osteoblast function in an age-dependent fashion in a mouse model of Paget's disease of bone.

Paget's disease of bone (PDB) is a degenerative disorder affecting the skull and bones. Hyperactive osteoclasts (OCs) initiate bone degradation in the early stage, followed by increased bone formation by osteoblasts (OBs) in trabecular bones during the advanced stage. This OB-OC uncoupling results in bone deformations and irregular trabecular bone patterns.

The metabolic influence of duodenal mucosal resurfacing for nonalcoholic fatty liver disease.

Background: Nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis (NASH) is a leading cause of chronic liver disease worldwide with decreased life expectancy. Duodenal mucosal resurfacing (DMR) has been associated with metabolic improvement in glycemic and hepatic parameters of type 2 diabetes, but the metabolic impact of DMR for NAFLD/NASH remains inconclusive. We conducted a meta-analysis to investigate metabolic effects of DMR in patients with NAFLD/NASH.

Artificial intelligence evaluation of coronary computed tomography angiography for coronary stenosis classification and diagnosis.

Background: Ruling out obstructive coronary artery disease (CAD) using coronary computed tomography angiography (CCTA) is time-consuming and challenging. This study developed a deep learning (DL) model to assist in detecting obstructive CAD on CCTA to streamline workflows.

Methods: In total, 2929 DICOM files and 7945 labels were extracted from curved planar reformatted CCTA images.

Cervical disc arthroplasty for magnetic resonance-evident cervical spondylotic myelopathy: comparison with anterior cervical discectomy and fusion.

Objective: Anterior cervical discectomy and fusion (ACDF) is a standard surgical approach for cervical spondylotic myelopathy (CSM) caused by disc herniations. Although cervical disc arthroplasty (CDA) has become, in the past decade, a viable alternative to ACDF in selected patients, the differences among patients with CSM treated with CDA and ACDF remain elusive. The effectiveness of motion preservation devices in CSM is also unclear.

Pretreatment diffusion-weighted imaging for prediction of relapsed and refractory primary central nervous system lymphoma.

Objectives: A subset of primary central nervous system lymphoma (PCNSL) has been shown to undergo an early relapsed/refractory (R/R) period after first-line chemotherapy.
