Optimizing COVID-19 testing capabilities and clinical management using pathology informatics.

Coronavirus disease 2019, first reported in China in late 2019, has quickly spread across the world. The outbreak was declared a pandemic by the World Health Organization on March 11, 2020. Here, we describe our initial efforts at the University of Florida Health for processing of large numbers of tests, streamlining data collection, and reporting data for optimizing testing capabilities and superior clinical management.

Informatics driven quality improvement in the modern histology lab.

Laboratory Information Systems (LIS) and data visualization techniques have untapped potential in anatomic pathology laboratories. Pre-built functionalities of LIS do not address all the needs of a modern histology laboratory. For instance, "Go live" is not the end of LIS customization, but just the beginning.

Coagulation Testing in the Core Laboratory.

Primary hemostasis begins with endothelial injury. VWF, produced by endothelial cells, binds to platelets and links them to subendothelial collagen. Platelet-derived ADP and thromboxane activate non-adhered platelets via their GPIIb/IIIa receptors, allowing these platelets to participate in platelet aggregation.

Making thawed universal donor plasma available rapidly for massively bleeding trauma patients: experience from the Pragmatic, Randomized Optimal Platelets and Plasma Ratios (PROPPR) trial.

Background: The Pragmatic, Randomized Optimal Platelets and Plasma Ratios (PROPPR) trial was a randomized clinical trial comparing survival after transfusion of two different blood component ratios for emergency resuscitation of traumatic massive hemorrhage. Transfusion services supporting the study were expected to provide thawed plasma, platelets, and red blood cells within 10 minutes of request.

Study Design And Methods: At the 12 Level 1 trauma centers participating in PROPPR, blood components transfused and delivery times were tabulated, with a focus on universal donor (UD) plasma management.

Secondary hyperparathyroidism in patients with untreated and treated congestive heart failure.

Background: The congestive heart failure syndrome includes a systemic illness with wasting of soft tissues and bone. We hypothesized secondary hyperparathyroidism (HPT) would be found in hospitalized patients with decompensated congestive heart failure (CHF), where secondary aldosteronism is expected, and who were either untreated or treated medically.

Methods: In 9 consecutive patients (7 males, 2 females; 8 African-American, 1 Caucasian; 33-60 yrs) admitted to the Regional Medical Center during a 28-day period with chronic left ventricular systolic dysfunction (EF<35%) and decompensated CHF (5 untreated; 4 treated with an angiotensin converting enzyme inhibitor, furosemide, and small-dose spironolactone), we measured: plasma parathyroid hormone (PTH); serum calcium corrected for albumin, magnesium, and phosphorus; serum creatinine and calculated creatinine clearance.

Clinical utility of the reticulocyte hemoglobin content in the diagnosis of iron deficiency.

Determination of the reticulocyte hemoglobin content (CHr) provides an early measure of functional iron deficiency because reticulocytes are the earliest erythrocytes released into blood and circulate for only 1 to 2 days. The CHr in 78 patients undergoing bone marrow examination was measured to assess its clinical utility for the diagnosis of iron deficiency. Twenty-eight patients were iron deficient, based on the lack of stainable iron in the aspirate.
