RESUMO

For many pathologists, the roles of the medical director are not clearly distinguished from other medical leadership and management duties, such as those of the chair of pathology or a section head of anatomic pathology. We describe the evolution in the understanding of the roles of the medical director as defined by the Clinical Laboratory Improvement Amendments of 1988 and separate from the roles of the chair of pathology, department chair, division chair, and a section head in anatomic pathology in our institution. Delineation of the roles of medical director, department chair, chair of anatomic pathology division, and a section head of a subdivision in anatomic pathology has helped us to understand the roles and ensure that all duties are fulfilled for patient care and for compliance and regulation.

RESUMO

BACKGROUND: Collecting a predefined set of blood tubes (the "rainbow draw") is a common but controversial practice in many emergency departments (EDs), with limited data to support it. We determined the actual utilization of rainbow draw tubes at a single facility and evaluated the perceptions of ED staff regarding the utility of rainbow draws. METHODS: We analyzed 2 weeks of ED visits (1326 visits by 1240 unique patients) to determine blood tube utilization for initial and add-on testing, as well as the incidence of additional venipunctures. We also surveyed ED staff regarding aspects of ED phlebotomy and test ordering. Utilization data analysis was structured to satisfy specific concerns addressed in the ED staff survey. RESULTS: Observed tube utilization data showed that fluoride/oxalate, citrate, and serum separator tubes were frequently discarded unused, and that the actual utility of the rainbow draw for add-on testing and avoiding additional venipunctures was low. ED staff perceived that the rainbow draw was highly valuable, both to expedite add-on testing and to avoid additional venipunctures. Contrasting the objective (utilization data) and subjective (survey results) to drive changes in the standard ED blood collection reduced the estimated waste blood by 175 L/year. CONCLUSIONS: Comparison of perceptions and objective utilization data drove process changes that were mutually agreeable to ED and laboratory staff. Although specifics of ED and laboratory work flows vary between institutions, the principles and strategy of this study are widely applicable.

RESUMO

Traditional medical training may actually impede a physician's ability to solve complex problems because it is based on vertical, linear and traditional thinking.

RESUMO

Burnout, a syndrome characterized by exhaustion, cynicism, and reduced effectiveness, does not spare pathologists, including cytopathologists, residents, and fellows. Burnout extracts a huge physician toll, resulting in decreased quality of care, poorer patient safety, increased physician turnover, and diminished patient satisfaction. In this review, we describe the drivers of burnout and suggest both individual and systemwide solutions that some centers have implemented to reverse the trend of increasing physician burnout.

RESUMO

BACKGROUND: Platelet polyphosphate is an inorganic procoagulant polymer of orthophosphate units that is stored in dense granules and is released upon platelet activation. Here, we describe an assay to measure polyphosphate on the surface of procoagulant human platelets. METHODS AND RESULTS: Recombinant Escherichia coli-expressed exopolyphosphatase deletion mutant PPX_Δ12 labeled with fluorescent Alexa488 dye was used as a polyphosphate probe in flow cytometry. PPX_Δ12-Alexa488-signal dose-dependently increased with long-chain polyphosphate binding to platelets. In contrast, short-chain polyphosphate that is found in the supernatant of activated platelets, did not bind to the platelet surface. Both exopolyphosphatase treatment and polyphosphate pre-incubation abolished PPX_Δ12-Alexa488 binding to polyphosphate on platelets. Stimulation of platelets with thrombin receptor agonist Trap6, and P2Y12 receptor activator ADP increased polyphosphate accumulation on platelet surfaces and PPX_Δ12-Alexa488 signal in a dose-dependent manner. CONCLUSION: This study indicates that long-chain polyphosphate binds to platelet plasma membranes and presents a promising diagnostic assay to measure this interaction on human platelets in platelet-rich plasma. Future investigations will aim to determine if polyphosphate can be used as a novel biomarker of thrombosis. © 2016 International Clinical Cytometry Society.

RESUMO

Polyphosphate is an inorganic procoagulant polymer. Here we develop specific inhibitors of polyphosphate and show that this strategy confers thromboprotection in a factor XII-dependent manner. Recombinant Escherichia coli exopolyphosphatase (PPX) specifically degrades polyphosphate, while a PPX variant lacking domains 1 and 2 (PPX_Δ12) binds to the polymer without degrading it. Both PPX and PPX_Δ12 interfere with polyphosphate- but not tissue factor- or nucleic acid-driven thrombin formation. Targeting polyphosphate abolishes procoagulant platelet activity in a factor XII-dependent manner, reduces fibrin accumulation and impedes thrombus formation in blood under flow. PPX and PPX_Δ12 infusions in wild-type mice interfere with arterial thrombosis and protect animals from activated platelet-induced venous thromboembolism without increasing bleeding from injury sites. In contrast, targeting polyphosphate does not provide additional protection from thrombosis in factor XII-deficient animals. Our data provide a proof-of-concept approach for combating thrombotic diseases without increased bleeding risk, indicating that polyphosphate drives thrombosis via factor XII.
