Despite achieving sustained virologic response (SVR) to hepatitis C virus (HCV) therapy, there remains a post liver transplantation population with advanced fibrosis/cirrhosis. Emricasan is an orally active, pan-caspase inhibitor that suppresses apoptosis and inflammation, potentially decreasing hepatic inflammation and fibrosis. We aimed to determine the safety and efficacy of emricasan (IDN-6556-07) in a double-blind, randomized, placebo-controlled, multicenter study in reducing or preventing the progression of hepatic fibrosis in HCV liver transplant recipients with residual fibrosis or cirrhosis after achieving SVR.

Article Synopsis
  • Hemostatic clots consist of a core of P-selectin positive platelets surrounded by a shell of P-selectin negative platelets.
  • A new microfluidic assay was developed to study the mechanics of these core/shell structures by using whole blood and various perfusion conditions.
  • Results showed that P-selectin-positive platelets remained stable in the clot, with thrombin aiding in their stability, while inhibiting certain factors led to a decrease in their numbers and overall clot stability.

Importance: Health care workers (HCWs) caring for patients with coronavirus disease 2019 (COVID-19) are at risk of exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Currently, to our knowledge, there is no effective pharmacologic prophylaxis for individuals at risk.

Objective: To evaluate the efficacy of hydroxychloroquine to prevent transmission of SARS-CoV-2 in hospital-based HCWs with exposure to patients with COVID-19 using a pre-exposure prophylaxis strategy.

Background Data regarding the phenotypic correlates and prognostic value of albumin in heart failure with preserved ejection fraction (HFpEF) are scarce. The goal of the current study is to determine phenotypic correlates (myocardial hypertrophy, myocardial fibrosis, detailed pulsatile hemodynamics, and skeletal muscle mass) and prognostic implications of serum albumin in HFpEF. Methods and Results We studied 118 adults with HFpEF.

Background Abnormal P-wave indices (PWIs)-reflecting underlying left atrial abnormality-are associated with increased risk of stroke independent of atrial fibrillation. We assessed whether abnormal PWIs are associated with incident dementia and greater cognitive decline, independent of atrial fibrillation and ischemic stroke. Methods and Results We included 13 714 participants (mean age, 57±6 years; 56% women; 23% black) who were followed for dementia through the end of 2015.

Article Synopsis
  • The study investigates VA cardiovascular clinicians' attitudes towards quality-of-care processes, clinical outcomes, and healthcare value through interviews with 31 providers from various VA hospitals.
  • Most participants were aware of process-of-care measurements and utilized regular feedback to modify their practices, but fewer used clinical outcomes data and almost none used value data to inform decision-making.
  • The findings suggest that while there is enthusiasm for quality measurement efforts, the limited use of clinical outcomes and value data could lead to inefficiencies and potentially impact patient care negatively.

Background: Next-generation sequencing (NGS) of surgically resected solid tumor samples has become integral to personalized medicine approaches for cancer treatment and monitoring. Liquid biopsies, or the enrichment and characterization of circulating tumor cells (CTCs) from blood, can provide noninvasive detection of evolving tumor mutations to improve cancer patient care. However, the application of solid tumor NGS approaches to circulating tumor samples has been hampered by the low-input DNA available from rare CTCs.

Often, high-sensitivity, point-of-care (POC) clinical tests, such as HIV viral load, require large volumes of plasma. Although centrifuges are ubiquitously used in clinical laboratories to separate plasma from whole blood, centrifugation is generally inappropriate for on-site testing. Suitable alternatives are not readily available to separate the relatively large volumes of plasma from milliliters of blood that may be needed to meet stringent limit-of-detection specifications for low-abundance target molecules.

S-nitrosylation of surfactant protein D as a modulator of pulmonary inflammation.

Biochim Biophys Acta

June 2012

Pulmonary, Allergy and Critical Care Division, Department of Medicine University of Pennsylvania, Vernon and Shirley Hill Pavilion, #H410C, 380 S. University Ave., Philadelphia, PA 19104-4539, USA.

Background: Surfactant protein D (SP-D) is a member of the family of proteins termed collagen-like lectins or "collectins" that play a role in non-antibody-mediated innate immune responses [1]. The primary function of SP-D is the modulation of host defense and inflammation [2].

Scope Of Review: This review will discuss recent findings on the physiological importance of SP-D S-nitrosylation in biological systems and potential mechanisms that govern SP-D mediated signaling.

Hyponatremia affects nearly one in five of all hospitalized patients. Severe hyponatremia is associated with significant morbidity and mortality, and is therefore important to recognize. Prior reports have linked duloxetine with hyponatremia, but it is uncommon.

Purpose: Using 123I for diagnostic purposes avoids the risk of stunning for subsequent radioiodine treatment and affords an excellent image quality. In this study we assessed the role of 123I in comparison with 131I post-treatment imaging in patients with thyroid cancer.

Methods: We compared a total of 292 123I scans with their corresponding post-treatment 131I images.
