Limb salvage reconstruction: Radiologic features of common reconstructive techniques and their complications.

Limb salvage surgery refers to orthopaedic procedures designed to resect tumors and reconstruct limbs. Improvements in managing malignant bone lesions have led to a dramatic shift in limb salvage procedures. Orthopaedic surgeons now employ four main reconstructive procedures: endoprosthesis, autograft, bulk allograft, and allograft prosthetic composite.

MRI of Superior Capsular Reconstruction.

Massive irreparable rotator cuff tears can be a challenging problem for arthroscopists in the perioperative setting because the typical treatment, reverse total shoulder arthroplasty, may not be the best option for all patients. Superior capsular reconstruction (SCR) is an advancing treatment option for patients with rotator cuff tears that are neither amenable to primary repair nor ideal for arthroplasty. Patient selection, which is strongly dependent on preoperative imaging findings, is an important step in obtaining favorable surgical outcomes.

Patient-Reported Knee Outcome Scores With Soft Tissue Quadriceps Tendon Autograft Are Similar to Bone-Patellar Tendon-Bone Autograft at Minimum 2-Year Follow-up: A Retrospective Single-Center Cohort Study in Primary Anterior Cruciate Ligament Reconstruction Surgery.

Background: Quadriceps tendon (QT)-bone autografts used during anterior cruciate ligament (ACL) reconstruction have provided comparable outcomes and decreased donor-site morbidity when compared with bone-patellar tendon-bone (BPTB) autografts. No study has directly compared the outcomes of the all-soft tissue QT autograft with that of the BPTB autograft.

Hypothesis: Patient-reported knee outcome scores and rates of postoperative complication after primary ACL reconstruction with QT autografts are no different from BPTB autografts at a minimum 2-year follow-up.

Novel approach to improve patient satisfaction in the outpatient clinic setting.

Background: With evolving reimbursement patterns and an emphasis on value-based care, patient satisfaction is increasingly becoming a more important metric. However, there remains a dearth of literature examining potential strategies to improve patient satisfaction in the outpatient setting. This study investigates if overall perception of care is influenced by providing biosketch cards to new patients in an outpatient Sports Medicine clinic.

Novel tricyclic glycal-based inducers that reprogram LDL metabolism in hepatic cells.

Increased expression of the Tribbles pseudokinase 1 gene () is associated with lower plasma levels of LDL cholesterol and triglycerides, higher levels of HDL cholesterol and decreased risk of coronary artery disease and myocardial infarction. We identified a class of tricyclic glycal core-based compounds that upregulate expression in human HepG2 cells and phenocopy the effects of genetic overexpression as they inhibit expression of triglyceride synthesis genes and ApoB secretion in cells. In addition to predicted effects related to downregulation of VLDL assembly and secretion these compounds also have unexpected effects as they upregulate expression of LDLR and stimulate LDL uptake.

Tissue Engineering and Cell-Based Therapies for Fractures and Bone Defects.

Bone fractures and segmental bone defects are a significant source of patient morbidity and place a staggering economic burden on the healthcare system. The annual cost of treating bone defects in the US has been estimated to be $5 billion, while enormous costs are spent on bone grafts for bone injuries, tumors, and other pathologies associated with defective fracture healing. Autologous bone grafts represent the gold standard for the treatment of bone defects.

High Throughput Screen Identifies Interferon γ-Dependent Inhibitors of Toxoplasma gondii Growth.

Toxoplasma gondii is an obligate intracellular parasite capable of causing severe disease due to congenital infection and in patients with compromised immune systems. Control of infection is dependent on a robust Th1 type immune response including production of interferon gamma (IFN-γ), which is essential for control. IFN-γ activates a variety of antimicrobial mechanisms in host cells, which are then able to control intracellular parasites such as T.

High-Throughput Screens To Identify Autophagy Inducers That Function by Disrupting Beclin 1/Bcl-2 Binding.

Autophagy, a lysosomal degradation pathway, plays a crucial role in cellular homeostasis, development, immunity, tumor suppression, metabolism, prevention of neurodegeneration, and lifespan extension. Thus, pharmacological stimulation of autophagy may be an effective approach for preventing or treating certain human diseases and/or aging. We sought to establish a method for developing new chemical compounds that specifically induce autophagy.

The Autophagy-Related Beclin-1 Protein Requires the Coiled-Coil and BARA Domains To Form a Homodimer with Submicromolar Affinity.

Beclin-1 (BECN1) is an essential component of macroautophagy. This process is a highly conserved survival mechanism that recycles damaged cellular components or pathogens by encasing them in a bilayer vesicle that fuses with a lysosome to allow degradation of the vesicular contents. Mutations or altered expression profiles of BECN1 have been linked to various cancers and neurodegenerative diseases.

Clinical and Economic Outcomes in Elderly Advanced Renal Cell Carcinoma Patients Starting Pazopanib or Sunitinib Treatment: A Retrospective Medicare Claims Analysis.

Introduction: Studies indicate similar survival and toxicity between pazopanib and sunitinib, but few have examined real-world outcomes among elderly patients with advanced renal cell carcinoma (RCC). The purpose of this retrospective claims analysis was to assess real-world overall survival (OS), healthcare resource utilization (HRU), and healthcare costs (both all-cause and associated with RCC diagnosis) among elderly advanced RCC patients starting pazopanib or sunitinib treatment.

Methods: Advanced RCC patients aged 65 years or older who started first-line treatment with pazopanib or sunitinib (index drug; the initiation date was the index date) were identified from the 100% Medicare database plus Part D linkage (January 1, 2006 to December 31, 2014).

Small-molecule inhibitors directly target CARD9 and mimic its protective variant in inflammatory bowel disease.

Advances in human genetics have dramatically expanded our understanding of complex heritable diseases. Genome-wide association studies have identified an allelic series of variants associated with increased risk of or protection from inflammatory bowel disease (IBD). The predisposing variant of CARD9 is associated with increased NF-κB-mediated cytokine production.

Small-molecule studies identify CDK8 as a regulator of IL-10 in myeloid cells.

Enhancing production of the anti-inflammatory cytokine interleukin-10 (IL-10) is a promising strategy to suppress pathogenic inflammation. To identify new mechanisms regulating IL-10 production, we conducted a phenotypic screen for small molecules that enhance IL-10 secretion from activated dendritic cells. Mechanism-of-action studies using a prioritized hit from the screen, BRD6989, identified the Mediator-associated kinase CDK8, and its paralog CDK19, as negative regulators of IL-10 production during innate immune activation.
