Microstructured Reflective Coatings on Commodity Textiles for Passive Personal Cooling.

As the effects of climate change become more severe and widespread, maintaining personal thermal homeostasis becomes necessary for survival. In principle, advanced textiles and garments have the ability to leverage light absorption, transmission and/or reflection, in addition to straightforward convection, to heat or cool bodies in extreme temperature conditions. For cooling, in particular, surfaces adept at selectively reflecting or refracting high-energy incident light (200 nm-2.

Rationale and design of ApoA-I Event Reducing in Ischemic Syndromes II (AEGIS-II): A phase 3, multicenter, double-blind, randomized, placebo-controlled, parallel-group study to investigate the efficacy and safety of CSL112 in subjects after acute myocardial infarction.

Acute myocardial infarction (MI) patients remain at high risk for recurrent events. Cholesterol efflux, mediated by apolipoprotein A-I, removes excess cholesterol from atherosclerotic plaque and transports it to the liver for excretion. Impaired cholesterol efflux is associated with higher cardiovascular (CV) event rates among both patients with stable coronary artery disease and recent MI.

Longitudinal Assessment of Health Symptoms in Relation to Neurotoxicant Exposures in 1991 Gulf War Veterans: The Ft. Devens Cohort.

Objective: This analysis examined the relationship between Gulf War (GW) exposures and health symptoms reported in three time periods over 20 years in Ft. Devens Cohort veterans.

Methods: Repeated logistic regression models examined the association of exposures and health symptoms over time.

Machine learning to predict venous thrombosis in acutely ill medical patients.

Background: The identification of acutely ill patients at high risk for venous thromboembolism (VTE) may be determined clinically or by use of integer-based scoring systems. These scores demonstrated modest performance in external data sets.

Objectives: To evaluate the performance of machine learning models compared to the IMPROVE score.

Relation of White Blood Cell Count to Bleeding and Ischemic Events in Patients With Acute Coronary Syndrome (from the ATLAS ACS 2-TIMI 51 Trial).

An elevated white blood cell (WBC) count is associated with an increased risk of ischemic events among acute coronary syndrome (ACS) patients, but the association between WBC count and bleeding in ACS patients is not well established. The aim of this analysis was to assess and compare the association between WBC count and the occurrence of short- and long-term bleeding and ischemic events. This was a post hoc analysis of the ATLAS ACS2-TIMI 51 trial.

A systematic review of randomized trials comparing double versus triple antithrombotic therapy in patients with atrial fibrillation undergoing percutaneous coronary intervention.

Background: Prior randomized controlled trials (RCT) evaluating the optimal antithrombotic therapies for patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) have not been powered to evaluate ischemic outcomes. We compared double therapy with oral anticoagulation (OAC) and a P2Y12 inhibitor to triple therapy with an OAC + dual antiplatelet therapy in patients with AF requiring PCI.

Methods: Using PRISMA guidelines, we searched for RCTs including patients with AF as an indication for OAC and undergoing PCI or medical management of acute coronary syndrome.

Novel Oral Anticoagulant Based Versus Vitamin K Antagonist Based Double Therapy Among Stented Patients With Atrial Fibrillation: Insights From the PIONEER AF-PCI Trial.

Background: Among stented patients with atrial fibrillation, double therapy with a novel oral anticoagulant plus single antiplatelet therapy (SAPT) reduces bleeding or cardiovascular rehospitalizations compared with a vitamin K antagonist (VKA) based triple therapy regimen. A recent study demonstrated that apixaban based double therapy reduced bleeding compared with VKA based double therapy. However, it remains unknown whether rivaroxaban based double therapy is superior to a VKA based double therapy.

Extended prophylaxis of venous thromboembolism with betrixaban in acutely ill medical patients with and without cancer: insights from the APEX trial.

Acutely ill medical patients with cancer are at increased risk of venous thromboembolism (VTE). Thromboprophylaxis is recommended in the presence of cancer, but its safety is not known. The aim of this study was to assess the efficacy and safety of extended prophylaxis with betrixaban in cancer patients enrolled in the APEX trial.

Net-clinical benefit of extended prophylaxis of venous thromboembolism with betrixaban in medically ill patients aged 80 or more.

Background: Extended-duration thromboprophylaxis with betrixaban reduces the risk of venous thromboembolism (VTE) without increasing major bleeding rates in acutely ill medical patients as compared to standard duration enoxaparin. We aimed to assess the risk-benefit of betrixaban in patients aged ≥ 80 years enrolled in the APEX trial.

Methods: APEX was a randomized, double-blind trial in which patients hospitalized for acute medical illnesses received enoxaparin 40 mg qd for 10 ± 4 days or oral betrixaban 80 mg qd for 35 to 42 days.

Characterization of Major and Clinically Relevant Non-Major Bleeds in the APEX Trial.

 Among medically ill patients treated with thromboprophylaxis, betrixaban was not associated with an increase in major bleeding compared with enoxaparin, but an increase in clinically relevant non-major (CRNM) bleeding was observed. The aim of this analysis is to describe the severity and clinical consequences of major and CRNM bleeding in the APEX trial.  The APEX trial randomized 7,513 hospitalized acutely ill medical patients to receive either enoxaparin for 6 to 14 days or betrixaban for 35 to 42 days.

Rates of Chronic Medical Conditions in 1991 Gulf War Veterans Compared to the General Population.

Prevalence of nine chronic medical conditions in the population-based Ft. Devens Cohort (FDC) of GW veterans were compared with the population-based 2013⁻2014 National Health and Nutrition Examination Survey (NHANES) cohort. Excess prevalence was calculated as the difference in prevalence estimates from the Ft.

Most Promising Therapies in Interventional Cardiology.

Purpose Of Review: The last 40 years of clinical research in interventional cardiology were extraordinarily innovative. This article will review the most promising up and coming interventional cardiovascular therapies, with a primary focus on the treatment of coronary artery disease.

Recent Findings: From the first stent, to the first transcatheter aortic valve implantation (TAVI), and the left appendage closure technique, percutaneous interventions revolutionized the treatment of multiple diseases and dramatically improved the prognosis of many patients.

Implantable Cardiac Alert System for Early Recognition of ST-Segment Elevation Myocardial Infarction.

Background: Symptoms remain a poor prompt for acute coronary syndromes (ACS). Timely restoration of perfusion in ST-segment elevation myocardial infarction is associated with improved left ventricular function and survival.

Objectives: This report details the results of ALERTS (AngelMed for Early Recognition and Treatment of STEMI), a multicenter, randomized trial of an implantable cardiac monitor that alerts patients with rapidly progressive ST-segment deviation.

Association of International Normalized Ratio Stability and Bleeding Outcomes Among Atrial Fibrillation Patients Undergoing Percutaneous Coronary Intervention.

Background: Among atrial fibrillation patients undergoing percutaneous coronary intervention enrolled in PIONEER AF-PCI (An Open-Label, Randomized, Controlled, Multicenter Study Exploring Two Treatment Strategies of Rivaroxaban and a Dose-Adjusted Oral Vitamin K Antagonist Treatment Strategy in Subjects With Atrial Fibrillation Who Undergo Percutaneous Coronary Intervention), it is unclear if the observed reduction in bleeding events with rivaroxaban regimens is consistent across a range of the international normalized ratio (INR) among subjects administrated Vitamin K antagonist (VKA)-triple therapy. This analysis compares the occurrence of clinically significant bleeding between rivaroxaban and VKA strategies, according to INR stability of subjects administrated VKA.

Methods And Results: A total of 2124 atrial fibrillation patients undergoing percutaneous coronary intervention were randomized to 3 groups: rivaroxaban 15 mg od plus a P2Y inhibitor (group 1, n=709); rivaroxaban 2.

The CSL112-2001 trial: Safety and tolerability of multiple doses of CSL112 (apolipoprotein A-I [human]), an intravenous formulation of plasma-derived apolipoprotein A-I, among subjects with moderate renal impairment after acute myocardial infarction.

Background: CSL112 (apolipoprotein A-I [human]) is a plasma-derived apolipoprotein A-I developed for early reduction of cardiovascular risk following an acute myocardial infarction (AMI). The safety of CSL112 among AMI subjects with moderate, stage 3 chronic kidney disease (CKD) is unknown.

Methods: CSL112_2001, a multicenter, placebo-controlled, parallel-group, double-blind, randomized phase 2 trial, enrolled patients with moderate CKD within 7 days following AMI.

Asymptomatic Deep Vein Thrombosis is Associated with an Increased Risk of Death: Insights from the APEX Trial.

Aim:  Asymptomatic deep vein thrombosis (DVT) diagnosed with compression ultrasound (CUS) is a common endpoint in trials assessing the efficacy of anticoagulants to prevent venous thromboembolism (VTE), but the relationship of asymptomatic thrombus to mortality remains uncertain.

Methods:  In the APEX trial (ClinicalTrials.gov: NCT01583218), 7,513 acutely ill hospitalized medical patients were randomly assigned to extended-duration betrixaban (35-42 days) or enoxaparin (10 ± 4 days).

Betrixaban for first-line venous thromboembolism prevention in acute medically ill patients with risk factors for venous thromboembolism.

Compared to other direct oral anticoagulants, betrixaban has a longer half-life, smaller peak-trough variance, minimal renal clearance, and minimal hepatic Cytochrome P (CYP) metabolism. The Acute Medically Ill VTE Prevention with Extended Duration Betrixaban (APEX) trial evaluated the efficacy and safety of extended duration betrixaban compared to standard duration enoxaparin in acutely ill hospitalized patients. Areas covered: This article describes the role of betrixaban in the prevention of venous thromboembolism (VTE) in acutely ill medical patients.

D-Dimer Levels and Effect of Rivaroxaban on Those Levels and Outcomes in Patients With Acute Coronary Syndrome (An ATLAS ACS-TIMI 46 Trial Substudy).

D-dimer has been used as both a diagnostic and prognostic biomarker in the assessment of patients with venous thromboembolism, but its prognostic value in the setting of arterial acute coronary syndromes (ACS) and the ability of pharmacotherapy to reduce D-dimer in ACS is less well characterized. It was hypothesized that elevated baseline D-dimer would be associated with poor clinical outcomes in ACS, and that Factor Xa inhibition with Rivaroxaban would reduce D-dimer acutely and chronically. The ATLAS ACS TIMI-46 trial assessed the safety and efficacy of rivaroxaban compared with placebo in ACS patients.

Fatal or Irreversible Bleeding and Ischemic Events With Rivaroxaban in Acute Coronary Syndrome.

Background: Net clinical outcome analyses of acute coronary syndrome (ACS) mingle fatal or irreversible events with survivable or reversible events that vary significantly in clinical impact.

Objectives: A comparison of efficacy and safety limited to fatal or irreversible ischemic and adverse or seriously harmful events is one way to assess net clinical outcome and risk-benefit overall, given the fact that these events have a similar clinical impact.

Methods: In the ATLAS ACS 2-TIMI 51 (Anti-Xa Therapy to Lower Cardiovascular Events in Addition to Standard Therapy in Subjects with Acute Coronary Syndrome-Thrombolysis In Myocardial Infarction) trial of rivaroxaban in the secondary prevention of events among patients with ACS treated with aspirin plus clopidogrel or ticlopidine (clopidogrel/ticlopidine) or aspirin alone, fatal and irreversible efficacy events including nonbleeding cardiovascular death, myocardial infarction, and ischemic stroke were compared to fatal or irreversible safety events, including fatal and intracranial bleeding.

Total bleeding with rivaroxaban versus warfarin in patients with atrial fibrillation receiving antiplatelet therapy after percutaneous coronary intervention.

Unlabelled: Among atrial fibrillation (AF) patients undergoing percutaneous coronary intervention (PCI), rivaroxaban with background antiplatelet therapy significantly reduced the first occurrence of bleeding compared to triple therapy with warfarin. This study hypothesized that total bleeding events, including those beyond the first event, would be reduced with rivaroxaban-based regimens. In the PIONEER AF-PCI trial, 2099 patients in the modified intention-to-treat population were randomized to three groups and followed for 12 months: (1) rivaroxaban 15 mg once daily plus a P2Y inhibitor (N = 696); (2) rivaroxaban 2.

Symptomatic event reduction with extended-duration betrixaban in acute medically ill hospitalized patients.

Background: Approximately 15%-30% of patients in trials of medical thromboprophylaxis will have missing compression ultrasound (CUS) data. The goal of the present analysis was to perform analyses to minimize missing data.

Methods: The APEX trial randomized 7,513 acutely medically ill hospitalized patients to thromboprophylaxis with either betrixaban for 35-42 days or enoxaparin for 6-14 days.

Meta-analysis of self-reported health symptoms in 1990-1991 Gulf War and Gulf War-era veterans.

Objectives: Across diverse groups of Gulf War (GW) veterans, reports of musculoskeletal pain, cognitive dysfunction, unexplained fatigue, chronic diarrhoea, rashes and respiratory problems are common. GW illness is a condition resulting from GW service in veterans who report a combination of these symptoms. This study integrated the GW literature using meta-analytical methods to characterise the most frequently reported symptoms occurring among veterans who deployed to the 1990-1991 GW and to better understand the magnitude of ill health among GW-deployed veterans compared with non-deployed GW-era veterans.

Association of D-dimer Levels with Clinical Event Rates and the Efficacy of Betrixaban versus Enoxaparin in the APEX Trial.

 Elevated D-dimer concentrations are associated with an increased risk of venous thromboembolism (VTE). However, they may also provide prognostic value. The present analysis sought to study the association of D-dimer levels with VTE event rates and the efficacy of betrixaban versus enoxaparin in the APEX trial.
