Early Diagnosis and Treatment of Cardiac Amyloidosis by Screening Biopsy During Trigger Finger Release.

Patients undergoing trigger release surgery are known to be at increased risk of amyloidosis and heart failure, and therefore, amyloidosis screening during trigger release surgery may facilitate early diagnosis and treatment of cardiac amyloidosis. However, the reported prevalence of amyloid on biopsies taken during trigger release surgery has varied widely, and no biopsy-positive patients in prior studies have been diagnosed with occult cardiac amyloidosis or started on disease-modifying therapy. We review the existing literature on this topic and present a case of a patient with cardiac amyloidosis diagnosed from a biopsy taken during trigger release surgery and subsequently started on disease-modifying therapy.

Musculoskeletal Tumor Society Member Survey: Intra-Operative Peripheral Margins in Soft Tissue Sarcoma.

Background And Objectives: Routine intraoperative peripheral margin sampling is often employed by musculoskeletal surgical oncologists. Several recommendations exist regarding this practice pattern. It is unknown what the practice patterns of Musculoskeletal Tumor Society (MSTS) members are.

Intraoperative Peripheral Frozen Margin Assessment in Soft Tissue Sarcoma.

Background/objectives: Intraoperative peripheral margin sampling in soft tissue sarcoma (STS) is a routine practice among musculoskeletal oncologists. Practice patterns are variable, and evidence to support it is lacking. Rates of peripheral margin sampling at our institution were analyzed in addition to its clinical utility and cost-effectiveness.

RedLionfish - fast Richardson-Lucy Deconvolution package for efficient point spread function suppression in volumetric data.

The experimental limitations with optics observed in many microscopy and astronomy instruments result in detrimental effects for the imaging of objects. This can be generally described mathematically as a convolution of the real object image with the point spread function that characterizes the optical system. The popular Richardson-Lucy (RL) deconvolution algorithm is widely used for the inverse process of restoring the data without these optical aberrations, often a critical step in data processing of experimental data.

Genetic Screen in a Preclinical Model of Sarcoma Development Defines Drivers and Therapeutic Vulnerabilities.

Purpose: High-grade complex karyotype sarcomas are a heterogeneous group of tumors with a uniformly poor prognosis. Within complex karyotype sarcomas, there are innumerable genetic changes but identifying those that are clinically relevant has been challenging.

Experimental Design: To address this, we utilized a pooled genetic screening approach, informed by The Cancer Genome Atlas (TCGA) data, to identify key drivers and modifiers of sarcoma development that were validated in vivo.
