Heparin-induced thrombocytopenia (HIT) is associated with severe and potentially lethal thrombotic complications. NETosis was recently shown to be an important driver of thrombosis in HIT. We investigated the role of reactive oxygen species (ROS) and nicotinamide adenine dinucleotide phosphate (NADPH) oxidase 2 (NOX2) and their contributions to thrombus development in HIT. We showed that neutrophil activation by HIT immune complexes induced ROS-dependent NETosis. Analysis of thrombi formed in a microfluidics system showed ROS production in both platelets and neutrophils, and abundant neutrophil extracellular traps (NETs) and ROS distributed throughout the clot. Neutrophil-targeted ROS inhibition was sufficient to block HIT-induced NETosis …

Coronary Slow-Flow Phenomenon As An Underrecognized And Treatable Source Of Chest Pain: Case Series And Literature Review., Chikezie Alvarez, Henry Siu, Md

Background. Coronary slow-flow phenomenon (CSFP) is characterized by delayed distal vessel opacification of contrast, in the absence of significant epicardial coronary stenosis. CSFP has been reported as a cause of chest pain and abnormal noninvasive ischemic tests and is often underrecognized. Material and Methods. Charts and angiographic records from our institution were reviewed to identify 15 consecutive patients who were diagnosed with CSFP from January 2016 to January 2017. Results. Of the 15 patients (4 females and 11 males) studied, the mean age was 59.1 years (range = 45-86 years); all had left ventricular ejection fraction >45% …

The 2017 Association of Pathology Chairs Annual Meeting included a session for department chairs and other department leaders on "how to deal with deans and academic medical center leadership." The session was focused on discussing ways to foster positive relationships with university, medical school, and health system leaders, and productively address issues and opportunities with them. Presentations and a panel discussion were provided by 4 former pathology chairs who subsequently have served as medical deans and in other leadership positions including university provost, medical center CEO, and health system board chair. There was a strong consensus among the participants on …

The Humoral Theory Of Transplantation: Epitope Analysis And The Pathogenicity Of Hla Antibodies., Edward J Filippone, John Farber
Department of Medicine Faculty Papers
Central to the humoral theory of transplantation is production of antibodies by the recipient against mismatched HLA antigens in the donor organ. Not all mismatches result in antibody production, however, and not all antibodies are pathogenic. Serologic HLA matching has been the standard for solid organ allocation algorithms in current use. Antibodies do not recognize whole HLA molecules but rather polymorphic residues on the surface, called epitopes, which may be shared by multiple serologic HLA antigens. Data are accumulating that epitope analysis may be a better way to determine organ compatibility as well as the potential immunogenicity of given HLA …

RATIONALE: Anti-inflammatory and vascular protective actions of adiponectin are well recognized. However, many fundamental questions remain unanswered.
OBJECTIVE: The current study attempted to identify the adiponectin receptor subtype responsible for adiponectin's vascular protective action and investigate the role of ceramidase activation in adiponectin anti-inflammatory signaling.
METHODS AND RESULTS: Adiponectin significantly reduced tumor necrosis factor (TNF)α-induced intercellular adhesion molecule-1 expression and attenuated TNFα-induced oxidative/nitrative stress in human umbilical vein endothelial cells. These anti-inflammatory actions were virtually abolished by adiponectin receptor 1 (AdipoR1-), but not AdipoR2-, knockdown (KD). Treatment with adiponectin significantly increased neutral ceramidase (nCDase) activity (3.7-fold; P87% of adiponectin-induced nCDase …

Medullary thyroid carcinoma (MTC) accounts for 15% of thyroid cancers. It arises in the C-cells of the thyroid, and is often metastatic at presentation. Approximately 75% of MTC cases are sporadic. Heritable MTC is subdivided into three categories: MEN2A, familial medullary thyroid carcinoma (FMTC), and MEN2B. Determination of the particular mutation may guide the timing of prophylactic total thyroidectomy in family members who carry the mutation.

ACTH-dependent Cushing’s syndrome results from excessive ACTH secretion from a pituitary gland adenoma (Cushing’s disease) in 80% of cases. Much less commonly, ectopic ACTH production occurs outside the pituitary gland, with the majority of those cases caused by bronchial carcinoids. A small number are due to excessive ACTH secretion by a pheochromocytoma.
