KLRG1 Cell Depletion as a Novel Therapeutic Strategy in Patients with Mature T-Cell Lymphoma Subtypes.

Purpose: Develop a novel therapeutic strategy for patients with subtypes of mature T-cell and NK-cell neoplasms.

Experimental Design: Primary specimens, cell lines, patient-derived xenograft models, commercially available, and proprietary anti-KLRG1 antibodies were used for screening, target, and functional validation.

Results: Here we demonstrate that surface KLRG1 is highly expressed on tumor cells in subsets of patients with extranodal NK/T-cell lymphoma (ENKTCL), T-prolymphocytic leukemia (T-PLL), and gamma/delta T-cell lymphoma (G/D TCL).

Clinical, pathological, genetics and intratumoural immune milieu of micropapillary carcinoma of the colon.

Aim: Micropapillary carcinoma (MPC) is a recognised WHO variant of colonic carcinoma (CC), although little is known about its prognosis, immune microenvironment and molecular alterations. We investigated its clinical, pathological and immunological characteristics.

Methods: We assessed 903 consecutive CCs and used the WHO definition to identify MPC.

Clinical, pathological genetics and intratumoral immune milieu of serrated adenocarcinoma of the colon.

Background: Serrated adenocarcinoma (SAC), a recognised WHO variant of colonic adenocarcinoma, is the purported end-product of serrated neoplasia. However, the diagnosis of SAC is infrequently rendered, and little is known about its prognosis, immune microenvironment and molecular alterations.

Materials And Methods: We assessed 903 consecutive colon carcinomas and recognised tumours with ≥ 5% (n = 77) serrated and ≥ 50% serrated patterns (n = 13).

Correlation of clinical, pathologic, and genetic parameters with intratumoral immune milieu in mucinous adenocarcinoma of the colon.

Mucinous adenocarcinoma (MAD), the most common subtype of colonic adenocarcinoma (CA), requires >50% intratumoral mucin. There is limited data regarding the impact of MAD on key lymphocyte subsets and therapeutically critical immune elements. In this study we address: (1) the definition of MAD, (2) grading of MAD, and (3) the impact of MAD and extracellular mucin on intratumoral immune milieu.

Practical Use of Thromboelastometry in the Management of Perioperative Coagulopathy and Bleeding.

Achieving hemostasis after complex cardiovascular and transplant surgical procedures is one of the greatest challenges anesthesiologists face. Preoperative coagulation disturbances due to underlying disease or antithrombotic therapy are common, and they are worsened by intraoperative blood loss and fluid replacement. The coagulation reactions in vivo are incredibly complex interactions among blood cells, proteins, and vasculature, standing in sharp contrast to rather simple treatment options including transfusion of platelets, plasma, and cryoprecipitate.

Therapeutic plasma exchange in heart transplantation: role of coagulation assessment with thromboelastometry.

Therapeutic plasma exchange (TPE) is a potentially life-saving procedure which effectively removes donor-specific human leukocyte antigen (HLA) antibodies from the bloodstream, allowing critically ill heart transplant recipients to receive a donor organ with less wait time, and reducing the risk of acute organ rejection. The bulk of coagulation factors is initially removed from the blood during TPE using albumin and is later replaced with allogeneic plasma. Coagulopathy may develop during TPE and then can persist due to intraoperative blood loss and hemodilution during surgery and cardiopulmonary bypass.

Insights into the role of oxidative stress in the pathology of Friedreich ataxia using peroxidation resistant polyunsaturated fatty acids.

Friedreich ataxia is an autosomal recessive, inherited neuro- and cardio-degenerative disorder characterized by progressive ataxia of all four limbs, dysarthria, areflexia, sensory loss, skeletal deformities, and hypertrophic cardiomyopathy. Most disease alleles have a trinucleotide repeat expansion in the first intron of the FXN gene, which decreases expression of the encoded protein frataxin. Frataxin is involved in iron-sulfur-cluster (ISC) assembly in the mitochondrial matrix, and decreased frataxin is associated with ISC-enzyme and mitochondrial dysfunction, mitochondrial iron accumulation, and increased oxidative stress.

Improving adherence with amlodipine/atorvastatin therapy: IMPACT study.

Hypertension is prevalent in the United States and remains uncontrolled. The primary objective of the study was to determine the effect of once-daily dosing of a combination therapy for blood pressure (BP) and dyslipidemia using home BP monitoring on reaching clinical BP and the effect of daily dosing of combination therapy on reaching lipid goals. The study was conducted in middle-aged, indigent, African Americans who had high-risk, resistant hypertension and dyslipidemia.
