BACKGROUND:Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19, can be detected in respiratory samples by Real-time Reverse Transcriptase (RT)-PCR or other molecular methods. Accessibility of diagnostic testing for COVID-19 has been limited by intermittent shortages of supplies required for testing, including flocked nasopharyngeal (FLNP) swabs. METHODS:We developed a 3D-printed nasopharyngeal (3DP) swab as a replacement of the FLNP swab. The performance of 3DP and FLNP swabs were compared in a clinical trial of symptomatic patients at three clinical sites (n=291) using three SARS-CoV-2 EUA tests: a modified version of the CDC Real-time Reverse Transcriptase (RT)-PCR Diagnostic …

Development Of A New Multiplex Real-Time Rt-Pcr Assay For Severe Acute Respiratory Syndrome Coronavirus 2 (Sars-Cov-2) Detection., W. Zhen, G. J. Berry

Journal Articles

This research describes the development of a new multiplex real-time RT-PCR test for detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), with primers designed to amplify a 108 bp target on the spike surface glycoprotein (S gene) and a hydrolysis TaqMan probe designed to specifically detect SARS-CoV-2. The limit of detection (LOD) and clinical performance of this new assay were evaluated. A LOD study with inactivated virus exhibited performance equal to the modified CDC assay, with a final LOD of 1301 ± 13 genome equivalents/mL for the Northwell Health Laboratories laboratory-developed test (NWHL LDT) versus 1249 ± 14 genome …

Histopathological Evaluation Of Placentas After Diagnosis Of Maternal Sars-Cov-2 Infection., M. Gulersen, L. Prasannan, H. T. Tam, C. N. Metz, B. Rochelson, N. Meirowitz, W. Shan, M. Edelman, K. A. Millington

Journal Articles

Background:The impact of maternal SARS-CoV-2 infection on placental histopathology is not well known. Objectives:To determine if significant placental histopathological changes occur after diagnosis of SARS-CoV-2 infection in pregnancy and whether these changes are correlated with the presence or absence of symptoms associated with infection. Study Design:Retrospective cohort study of women diagnosed with SARS-CoV-2 infection who delivered at a single center from April 9th to April 27th, 2020, and had placental specimens reviewed by pathology. Women with singleton gestations and laboratory-confirmed SARS-CoV-2 infection were eligible for inclusion. Historical controls selected from a cohort of women who delivered 6 months prior to …

BACKGROUND:In March 2020, the greater New York metropolitan area became an epicenter for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The initial evolution of case incidence has not been well characterized. METHODS:Northwell Health Laboratories tested 46,793 persons for SARS-CoV-2 from March 4 through April 10. The primary outcome measure was a positive reverse-transcription-polymerase-chain-reaction (RT-PCR) test for SARS-CoV-2. The secondary outcomes included patient age, sex, and race if stated; dates the specimen was obtained and the test result; clinical practice site sources; geo-location of patient residence; and hospitalization. RESULTS:From March 8 through April 10, a total of 26,735 of 46,793 …

Background: The impact of maternal severe acute respiratory syndrome coronavirus 2 infection on placental histopathology is not well known.

Objective: To determine if any significant placental histopathologic changes occur after the diagnosis of severe acute respiratory syndrome coronavirus 2 infection during pregnancy and whether these changes are correlated with the presence or absence of symptoms associated with the infection.

Study Design: A retrospective cohort study of women diagnosed as having severe acute respiratory syndrome coronavirus 2 infection who delivered at a single center from April 9, 2020 to April 27, 2020, and had placental specimens reviewed by the Department of …

Ass1 Overexpression: A Hallmark Of Sonic Hedgehog Hepatocellular Adenomas; Recommendations For Clinical Practice., M. Sala, D. Gonzales, T. Leste-Lasserre, N. Dugot-Senant, V. Paradis, S. Di Tommaso, J. Dupuy, V. Pitard, C. Fan, F. Saltel, +26 Additional Authors

Journal Articles

Until recently, 10% of hepatocellular adenomas (HCAs) remained unclassified (UHCA). Among the UHCAs, the sonic hedgehog HCA (shHCA) was defined by focal deletions that fuse the promoter of Inhibin beta E chain with GLI1. Prostaglandin D2 synthase was proposed as immunomarker. In parallel, our previous work using proteomic analysis showed that most UHCAs constitute a homogeneous subtype associated with overexpression of argininosuccinate synthase (ASS1). To clarify the use of ASS1 in the HCA classification and avoid misinterpretations of the immunohistochemical staining, the aims of this work were to study (1) the link between shHCA and ASS1 overexpression and (2) the …

The Value Proposition For Pathologists: A Population Health Approach, B. S. Ducatman, A. M. Ducatman, J. M. Crawford, M. Laposata, F. Sanfilippo

Journal Articles

© The Author(s) 2020. The transition to a value-based payment system offers pathologists the opportunity to play an increased role in population health by improving outcomes and safety as well as reducing costs. Although laboratory testing itself accounts for a small portion of health-care spending, laboratory data have significant downstream effects in patient management as well as diagnosis. Pathologists currently are heavily engaged in precision medicine, use of laboratory and pathology test results (including autopsy data) to reduce diagnostic errors, and play leading roles in diagnostic management teams. Additionally, pathologists can use aggregate laboratory data to monitor the health of …

Multiple Myeloma In A Young Female Presenting With Neurological Symptoms., M. Lee, X. Zhang, V. Nguyen, M. Hartley-Brown

Journal Articles

Background:Multiple myeloma is overall the 14th most common malignancy but is rarely seen in those younger than 35 years. Those in the younger age group have been shown to have a more aggressive course but reportedly have had similar responses to treatment compared to older cohorts. Extramedullary plasmacytomas are discrete soft tissue masses of neoplastic monoclonal plasma cells that often occur in patients with multiple myeloma. Case:This case entails a young female with new diagnosis of multiple myeloma and multiple extramedullary plasmacytomas presenting with neurological symptoms. She was treated with CyBorD regimen but was refractory and progressed. Treatment was changed …

The clinical signs and symptoms of acute respiratory tract infections (RTIs) are not pathogen specific. Highly sensitive and specific nucleic acid amplification tests have become the diagnostic reference standard for viruses and translation of bacterial assays from basic research to routine clinical practice represents an exciting advance in respiratory medicine. Most recently, molecular diagnostics have played an essential role in the global health response to the novel coronavirus pandemic. How best to use newer molecular tests for RTI in combination with clinical judNorthwell Healthnt and traditional methods can be bewildering given the plethora of available assays and rapidly evolving technologies. …

Lear, K. Maloney, J. K. Pinckard, P. Lin, T. Andrew, A. K. Williamson, O. Devinsky, +8 Additional Authors

Journal Articles

Importance: The true incidence of sudden unexplained death in childhood (SUDC), already the fifth leading category of death among toddlers by current US Centers for Disease Control and Prevention estimates, is potentially veiled by the varied certification processes by medicolegal investigative offices across the United States. Objective: To evaluate the frequency of SUDC incidence, understand its epidemiology, and assess the consistency of death certification among medical examiner and coroner offices in the US death investigation system. Design, Setting, and Participants: In this case series, 2 of 13 forensic pathologists (FPs) conducted masked reviews of 100 cases enrolled in the SUDC …
