Association of perioperative RBC transfusions with venous thromboembolism
August 2018—Hospital-associated venous thromboembolism is a major cause of morbidity and mortality, resulting in 100,000 to 200,000 deaths annually. Surgery can lead to a proinflammatory state and be a prothrombotic stimulus for venous thromboembolism (VTE). General anesthesia, as well as red blood cells transfused in the perioperative setting, is considered an independent risk factor for VTE.

Analysis of the surveillance of women diagnosed with atypical ductal hyperplasia on core needle biopsy
August 2018—A needle core biopsy diagnosis of atypical ductal hyperplasia is an indication for open biopsy. The launch of randomized clinical trials of active surveillance for low-risk ductal carcinoma in situ leads to the paradoxical situation of women with low-grade ductal carcinoma in situ being observed and those with atypical ductal hyperplasia having surgery.
Molecular Pathology Abstracts
Prevalence of clonal hematopoiesis mutations in tumor-only clinical genomic profiling of solid tumors
August 2018—Challenges to implementing next-generation sequencing-based comprehensive molecular profiling of solid tumors include reliably separating germline variants from somatic variants. This is an important consideration, particularly when a “tumor-only” profiling approach is used.

New digital pathology certificate program educates ‘from A to Z’
August 2018—While there’s a lot of buzz about the growth of digital pathology, its steep learning curve is a potential impediment to implementation. Recognizing this, the National Society for Histotechnology, in collaboration with the Digital Pathology Association, launched in May a web-based digital pathology certificate program designed to provide both a broad overview of digital pathology and a deep dive into the details.

High-sensitivity troponin I assay available in the U.S.
July 2018—Beckman Coulter Diagnostics received 510(k) clearance from the Food and Drug Administration for its new high-sensitivity troponin assay, Access hsTnI, for use on the Access 2, DxI, and the entire Access family of immunoassay systems. Access hsTnI demonstrates less than 10 percent CV at the upper reference limits for men and women and detects troponin in more than 50 percent of the healthy population. In an independent study, Access hsTnI detected more than 99 percent of troponin values for healthy men and women (Pretorius CJ, et al. Clin Biochem. 2018;55:49–55). “Beckman Coulter’s high-sensitivity cardiac troponin I assay can measure very low cardiac troponin concentrations with excellent precision. This test may help physicians with both the early diagnosis of myocardial infarction and future risk stratification in and outside the acute coronary syndrome setting,” Peter Kavsak, PhD, associate professor, Department of Pathology and Molecular Medicine, McMaster University, said in a statement.

Trends in perioperative RBC transfusion from index cases in five surgical specialties
July 2018—In recent years, greater attention has been given to patient blood management. While contemporary national guidelines recommend restrictive red blood cell transfusion, it is not known whether such transfusions have decreased in surgical patients. Approximately 11 million RBC transfusions are performed annually, and two-thirds of those are for patients in the perioperative period.
Q&A column
July 2018—Is CD30 currently being used as a predictive marker for therapy? Due to laboratory construction, our molecular instruments were relocated within the lab. Is full test validation required in this case? Or is running at least 20 known samples enough to verify the instrument/assay performance specifications?
President’s Desk: From concept to fruition

July 2018—How a geospacial tracking system is closing the distance at Michigan lab: This summer, when the Michigan Medicine Department of Pathology moves the last of its laboratories to a new campus four-and-a-half miles from the existing University Hospital laboratories in Ann Arbor, it will kick its new PathTrack Lean-influenced real-time geospatial tracking system into high gear. Developing the system, which will monitor an anticipated 6,000 to 10,000 specimens every day, has been “a monumental effort,” says Ulysses J. Balis, MD, director of the health system’s division of pathology informatics.
