Contemporary coronary artery bypass graft surgery and subsequent percutaneous revascularization.

Patients who have undergone coronary artery bypass graft (CABG) surgery are susceptible to bypass graft failure and progression of native coronary artery disease. Although the saphenous vein graft (SVG) was traditionally the most-used conduit, arterial grafts (including the left and right internal thoracic arteries and the radial artery) have improved patency rates. However, the need for secondary revascularization remains common, and percutaneous coronary intervention (PCI) has become the most common modality of secondary revascularization after CABG surgery.

Alcohol Consumption and Systemic Hypertension (from the Third National Health and Nutrition Examination Survey).

Epidemiological studies have established the association between excessive alcohol consumption and systemic hypertension (SH). However, there are conflicting reports of the association of low to moderate alcohol consumption with SH. The objective of the study was to examine the associations of alcohol consumption and blood pressure categories using the 2017 American College of Cardiology/American Heart Association high blood pressure guidelines.

Hatching date influences winter habitat occupancy: Examining seasonal interactions across the full annual cycle in a migratory songbird.

Birds experience a sequence of critical events during their life cycle, and past events can subsequently determine future performance via carry-over effects. Events during the non-breeding season may influence breeding season phenology or productivity. Less is understood about how events during the breeding season affect individuals subsequently in their life cycle.

Effect of metformin on the high-density lipoprotein proteome in youth with type 1 diabetes.

Background: Youth with type 1 diabetes (T1D) have normal or elevated High-Density Lipoprotein Cholesterol (HDL-C), however, the function of HDL, partly mediated by the HDL proteome, may be impaired. Metformin can be used as an adjunct therapy in youth with T1D, but its effects on the HDL proteome are unknown.

Objective: To determine the effect of metformin on the HDL proteome.

SARS-CoV-2 infection and paediatric endocrine disorders: Risks and management considerations.

Background: Coronavirus-19 (COVID-19) is a disease caused by the SARS-CoV-2 virus, the seventh coronavirus identified as causing disease in humans. The SARS-CoV-2 virus has multiple potential pathophysiologic interconnections with endocrine systems, potentially causing disturbances in glucose metabolism, hypothalamic and pituitary function, adrenal function and mineral metabolism. A growing body of data is revealing both the effects of underlying endocrine disorders on COVID-19 disease outcome and the effects of the SARS-CoV-2 virus on endocrine systems.

Rapid organocatalytic chirality analysis of amines, amino acids, alcohols, amino alcohols and diols with achiral iso(thio)cyanate probes.

The widespread occurrence and significance of chiral compounds does not only require new methods for their enantioselective synthesis but also efficient tools that allow rapid determination of the absolute configuration, enantiomeric composition and overall concentration of nonracemic mixtures. Although chiral analysis is a frequently encountered challenge in the chemical, environmental, materials and health sciences it is typically addressed with slow and laborious chromatographic or NMR spectroscopic techniques. We now show with almost 40 analytes representing 5 different compound classes, including mono-alcohols which are particularly challenging sensing targets, that this task can be solved very quickly by chiroptical sensing with a single, readily available arylisocyanate probe.

Comparing surgical thoroughness and recurrence in thyroid cancer patients across race/ethnicity.

Background: For patients with differentiated thyroid cancer who will receive postoperative radioactive iodine, thyroid remnant uptake can be calculated and may point to the thoroughness of the surgical resection. In the United States, outcome disparities exist among ethnic/racial minorities with differentiated thyroid cancer. Data about surgical thoroughness and recurrence rates across races/ethnicities do not exist.

However, its long-term influence on career development remains unknown. Our study explored the impact of MERC at CORD on career development through the lens of social cognitive career (SCC) theory.

Right Ventricular Pressure-Volume Analysis During Left Ventricular Assist Device Speed Optimization Studies: Insights Into Interventricular Interactions and Right Ventricular Failure.

Background: Interventricular interaction, which refers to the impact of left ventricular (LV) function on right ventricular (RV) function and vice versa, has been implicated in the pathogenesis of RV failure in LV assist device (LVAD) recipients. We sought to understand more about interventricular interaction by quantifying changes in the RV systolic and diastolic function with varying LVAD speeds.

Methods And Results: Four patients (ages 22-69 years, 75% male, and 25% with ischemic cardiomyopathy) underwent a protocolized hemodynamic ramp test within 12 months of LVAD implantation where RV pressure-volume loops were recorded with a conductance catheter.

Characterization of floral insect community and activity of three native bees.

(black willow) is a widespread tree that hosts many species of polylectic hymenopterans and oligolectic bees of the genus . The early flowering of makes it an important nutritive resource for arthropods emerging from hibernation. However, since is dioecious, not all insect visits will lead to successful pollination.

Gene expression profiling impacts treatment decision making in newly diagnosed multiple myeloma patients in the prospective PROMMIS trial.

Multiple myeloma (MM) is a heterogeneous hematologic malignancy associated with several risk factors including genetic aberrations which impact disease response and survival. Thorough risk classification is essential to select the best clinical strategy to optimize outcomes. The SKY92 molecular signature classifies patients as standard- or high-risk for progression.

Planning for health equity in the Americas: an analysis of national health plans.

There is growing recognition that health and well-being improvements have not been shared across populations in the Americas. This article analyzes 32 national health sector policies, strategies, and plans across 10 different areas of health equity to understand, from one perspective, how equity is being addressed in the region. It finds significant variation in the substance and structure of how the health plans handle the issue.

Cancer Cell Invasion and Metastasis in Zebrafish Models (Danio rerio).

Cancer cell vascular invasion and extravasation at metastatic sites are hallmarks of malignant progression of cancer and associated with poor disease outcome. Here we describe an in vivo approach to study the invasive ability of cancer cells into the vasculature and their hematogenous metastatic seeding in zebrafish (Danio rerio). In one approach, extravasation of fluorescently labeled cancer cells is monitored in zebrafish embryos whose vasculature is marked by a contrasting fluorescent reporter.

The incidence of hepatocellular carcinoma (HCC) is growing in the United States, especially among the elderly. Older patients are increasingly receiving transplants as a result of HCC, but the impact of advancing age on long-term posttransplant outcomes is not clear. To study this, we used data from the US Multicenter HCC Transplant Consortium of 4980 patients.

Rupture of Papillary Muscle and Chordae Tendinae Complicating STEMI: A Call for Action.

Papillary muscle rupture (PMR) or chordae tendinae rupture (CTR) is a rare but lethal complication after ST elevation myocardial infarction (STEMI). Due to the rarity of this condition, there are limited studies defining its epidemiology and outcomes. This is a retrospective study from Nationwide Inpatient Sample database from 2002 to 2014 of patients with STEMI and PMR/CTR.

Cross-Sectional Assessment of Burn Center and Nonburn Center Patient Care: A Multi-Database Comparison.

The practice of burn care is complex and continues to be a rapidly evolving field. To assess how differences in management affect hospital stay characteristics and outcomes, the authors sought to compare outcomes data from two sources, such as burn center and nonburn center data. The National Burn Repository (NBR, version 8) and the 2014 Nationwide Readmission Database (NRD) were compared based on ICD-9 948-series burn-related diagnosis codes, generating a total of 83,068 and 14,131 burn patients from the NBR and NRD, respectively.
