Risk factors and provider awareness of sexually transmitted enteric pathogens among men who have sex with men.

Sexual transmission of enteric pathogens among men who have sex with men (MSM) is well documented, although whether providers are cognizant of this risk when MSM patients present with gastrointestinal symptoms has not been studied. Over 34 months at a major tertiary metropolitan medical system, this study retrospectively analyzed 436 BioFire FilmArray Gastrointestinal results from 361 patients documented as MSM. An extensive chart review was performed, including specific sexual behaviors, socioeconomic risk factors, and whether providers charted a sexual history when a patient presented for care. Overall BioFire positivity rate was 62% with no significant difference in positivity between persons living with HIV and those without. Patients charted as sexually active had a significantly increased odds ratio (OR) of a positive result compared to those who were not. Anilingus had the highest OR. Providers charted any type of sexual history in 40.6% of cases, and HIV/infectious disease providers were significantly more likely to do this compared to other subspecialties. Sexual transmission of enteric pathogens within MSM is ongoing, and patients are at risk regardless of living with HIV. Not all sexual behaviors have the same associated risk, highlighting opportunities to decrease transmission. Increased provider vigilance and better patient education on sexual transmission of enteric pathogens are needed to reduce the disease burden. IMPORTANCE: Our work adds several key findings to the growing body of literature describing the epidemiology of enteric pathogens as sexually transmitted infections among men who have sex with men (MSM). We analyzed clinical test results, housing status, provider awareness, sexual behaviors, and symptoms for 361 patients. We found that any sexual activity was associated with an increased risk of diarrheal pathogen detection, whereas being unhoused was not a risk factor. These findings suggest separate transmission networks between unhoused persons, who are also at risk of infectious diarrhea, and MSM. Moreover, our study suggested low awareness among patient-facing clinicians that diarrheal pathogens can be sexually transmitted. Together, our findings indicate an important opportunity to disrupt transmission cycles by educating clinicians on how to assess and counsel MSM patients.

Novel low-grade renal spindle cell neoplasm with HEY1::NCOA2 fusion that is distinct from mesenchymal chondrosarcoma.

HEY1-NCOA2 fusion is most described in mesenchymal chondrosarcoma. This is the first case report of a primary renal spindle cell neoplasm of uncertain malignant potential with a HEY1::NCOA2 fusion identified by Fusionplex RNA-sequencing that is histologically distinct from mesenchymal chondrosarcoma. The neoplasm was identified in a 33-year-old woman without significant past medical history who underwent partial nephrectomy for an incidentally discovered renal mass. The histologic features of the mass included spindle cells with variable cellularity and monotonous bland cytology forming vague fascicles and storiform architecture within a myxoedematous and collagenous stroma with areas of calcification. The morphologic and immunophenotypic features were not specific for any entity but were most similar to low-grade fibromyxoid sarcoma. To date, the patient has not had recurrence, and the malignant potential of the neoplasm is uncertain.

Error Reduction and Diagnostic Concordance in Breast Pathology.

Errors in anatomic pathology can result in patients receiving inappropriate treatment and poor patient outcomes. Policies and procedures are necessary to decrease error and improve diagnostic concordance. Breast pathology may be more prone to diagnostic errors than other surgical pathology subspecialties due to inherit borderline diagnostic categories such as atypical ductal hyperplasia and low-grade ductal carcinoma in situ. Mandatory secondary review of internal and outside referral cases before treatment is effective in reducing diagnostic errors and improving concordance. Assessment of error through amendment/addendum tracking, implementing an incident reporting system, and multidisciplinary tumor boards can establish procedures to prevent future error.

Operational Impacts of the Coronavirus Disease 2019 (COVID-19) Pandemic and Early Recovery Trends: University of Washington Anatomic Pathology Experience.

CONTEXT.­: The coronavirus disease 2019 pandemic, caused by the novel coronavirus severe acute respiratory syndrome coronavirus 2, has resulted in worldwide disruption to the delivery of patient care. The Seattle, Washington metropolitan area was one of the first in the United States affected by the pandemic. As a result, the anatomic pathology services at the University of Washington experienced significant changes in operational volumes early in the pandemic. OBJECTIVE.­: To assess the impact of coronavirus disease 2019 and both state and institutional policies implemented to mitigate viral transmission (including institutional policies on nonurgent procedures) on anatomic pathology volumes. DESIGN.­: Accessioned specimens from January to June 2020 were evaluated as coronavirus disease 2019 and institutional policies changed. The data were considered in these contexts: subspecialty, billable Current Procedural Terminology codes, and intraoperative consultation. Comparable data were retrieved from 2019 as a historical control. RESULTS.­: There was a significant reduction in overall accessioned volume (up to 79%) from prepandemic levels during bans on nonurgent procedures when compared with 2020 pre-coronavirus disease 2019 volumes and historical controls. The gastrointestinal and dermatopathology services were most impacted, and breast and combined head and neck/pulmonary services were least impacted. Current Procedural Terminology code 88305, for smaller/biopsy specimens, had a 63% reduction during nonurgent procedure bans. After all bans on procedures were lifted, the overall volume plateaued at 89% of prepandemic levels. CONCLUSIONS.­: A significant decrease in specimen volume was most strongly associated with bans on nonurgent procedures. Although all departmental areas had a decrease in volume, the extent of change varied across subspecialty and specimen types. Even with removal of all bans, service volume did not reach prepandemic levels.
