Screening for Zika virus in US armed services blood program donors: An opportunity to compare emerging infectious disease risk between the general US population and military donors.

BACKGROUND: The U.S. Department of Defense (DoD) collects blood from volunteer DoD donors in U.S. Food and Drug Administration (FDA)-regulated centers, and from emergency donor panels in overseas operations. Emerging infectious diseases could reduce DoD access to blood products. In August 2016, FDA determined that Zika virus was transfusion-transmitted and advised that donated blood should be screened for Zika utilizing one of two investigational new drug (IND) applications. The Armed Services Blood Program (ASBP) tested blood using its own protocol concurrently with the IND study sponsored by Roche Molecular Systems, Inc., titled "A Prospective Study to Evaluate the Specificity of the cobas Zika test for use on the cobas 6800/8800 System for Screening of Blood Donations for the Presence of Zika virus RNA." STUDY DESIGN AND METHODS: This prospective clinical trial (September 2016-August 2017) evaluated the specificity of the cobas Zika 6800/8800 System. Consenting volunteers were screened for Zika by participating reference labs. Participants with positive screens were offered a follow-up study using alternative PCR and serology assays. RESULTS: 92,618 DoD donors enrolled; four tested positive on screening (0.0043%; CI 0.001176896%, 0.01105894%). Three enrolled in follow-up testing and none were positive. These results were comparable to all U.S. donors: 3,858,114 enrolled (excluding Puerto Rico) with 459 positive screens (0.0119%; CI 0.01083582%, 0.01303962%). CONCLUSION: The study demonstrated the effectiveness of the cobas Zika test. DoD donors, who are included in emergency donor panels during military operations, were at no higher risk for Zika than the overall U.S. donor population.

Key Principles Underlying a Research-Practice Alignment in a Federally Qualified Health Center.

Context: Minoritized populations such as racial and ethnic minorities and individuals of less privileged socioeconomic status experience a disproportionate burden of poor hypertension (HTN) control in the United States. Multilevel systems interventions have been shown to improve patient-level outcomes in minoritized populations; however, there remains a large translational gap in implementing these approaches into federally qualified health centers (FQHC), which serve those at highest risk of HTN-related morbidity and mortality. The paucity of purposeful collaborations between academic researchers and practice staff throughout the research process remains a significant roadblock to the timely translation of evidence to practice. Design: This commentary describes the key principles and best practices that underlie the development and sustainment of an equitable research-practice alignment, which is supporting the implementation of multilevel systems intervention for improved HTN care in a large FQHC in Brooklyn, New York. The key principles, which are derived from the central tenants of relationship development and maintenance in community-engaged participatory research, patient-centered outcomes research, and organizational alignment theory include (1) cocreation of a shared mental model, (2) bridging multilevel communication, (3) ensuring mutual accountability, and (4) creating a culture of continuous improvement. Conclusions: Together, the principles guide how the research and practice teams work together to achieve a shared goal of improving the health and well-being of minoritized patients through the provision of high quality, community-oriented HTN care. Best practices to sustain our alignment require an ongoing and deliberate investment in honest and transparent communication by all members.

Partial Gastric Resection for Symptomatic Anemia following Diagnosis of Merkel Cell Carcinoma (MCC) of the Skin with Gastric Metastasis.

Merkel Cell Carcinoma (MCC) is a rare dermatologic malignancy with significant morbidity and mortality associated with metastatic disease. In this case, we discuss and extremely rare presentation of MCC with metastasis to the stomach in a patient that presented with profound anemia. Unfortunately, mortality following diagnosis of MCC with gastric metastasis approaches 67% at 4 months based on available published reports. Due to its rarity and high rate of mortality, there is a lack of available research and literature to help guide treatment of this rare presentation of MCC. This case report presents a positive outcome associated with a partial gastrectomy for the treatment of symptomatic MCC with gastric metastasis and continued survival with persistently stable hemoglobin at 12 months. Key clinical message: Anemia may be a significant cause of the morbidity and mortality associated with MCC with gastric metastasis. Our case demonstrates a positive outcome associated with partial gastric resection and presents a possible treatment option for this rare disease process.

A rare presentation of an ACTH-producing high-grade large cell neuroendocrine carcinoma with Cushing's syndrome.

High-grade neuroendocrine tumors (HGNET) are rare neoplasms composed of neural and hormonal with only around 42 cases reported in the last 20 years1. Herein, we describe a rare case of pancreatic HGNET, large cell type, associated with a Cushing's syndrome presentation.

Gamma-Delta T-Cell Lymphoma Following Allogeneic Stem Cell Transplant for Primary Myelofibrosis.

Primary myelofibrosis (PMF) is a disease that affects the bone marrow. It presents with cytopenias, hepatospleomegaly accompanied with extramedullary hematopoiesis, and often with constitutional symptoms. Cytotoxic gamma-delta T-cells are considered a distinct hepatosplenic lymohoma. This is a case presentation of a 43-year-old male with an initial diagnosis of PMF who underwent allogeneic stem cell transplantation complicated by primary graft failure. He subsequently underwent a partial splenic embolization; however, he quickly developed a fulminant hepatosplenic gamma-delta T-cell lymphoma which led to his death that was diagnosed posthumously. PMF has been known to transform into an acute myeloid leukemia, but there has been no established link with gamma-delta T-cell lymphoma.

A Telemedicine Approach to Covid-19 Assessment and Triage.

Covid-19 is a new highly contagious RNA viral disease that has caused a global pandemic. Human-to-human transmission occurs primarily through oral and nasal droplets and possibly through the airborne route. The disease may be asymptomatic or the course may be mild with upper respiratory symptoms, moderate with non-life-threatening pneumonia, or severe with pneumonia and acute respiratory distress syndrome. The severe form is associated with significant morbidity and mortality. While patients who are unstable and in acute distress need immediate in-person attention, many patients can be evaluated at home by telemedicine or videoconferencing. The more benign manifestations of Covid-19 may be managed from home to maintain quarantine, thus avoiding spread to other patients and health care workers. This document provides an overview of the clinical presentation of Covid-19, emphasizing telemedicine strategies for assessment and triage of patients. Advantages of the virtual visit during this time of social distancing are highlighted.

Tranexamic Acid Use in a Patient with a Life-threatening Bleed Exacerbated by Coagulopathy Due to an Aortic Aneurysm with an Endoleak: A Case Report.

Tranexamic acid (TXA) is an anti-fibrinolytic agent that inhibits plasminogen activation by binding to its lysine receptor sites and preventing its conversion to plasmin. It stabilizes clots to reduce bleeding and has been used in the setting of trauma, heavy menstrual bleeding, and hematologic malignancies. To our knowledge, there is no mention in the literature of medical management with TXA to treat a life-threatening hemorrhage in the setting of non-operative, endoleakage-induced, chronic disseminated intravascular coagulation (DIC). This case report summarizes the successful use of TXA in a patient with DIC secondary to multiple aortic aneurysms and endoleakage in an effort to stop the expansion of a life-threatening gluteal hematoma not amenable to surgical or vascular intervention.
