OBJECTIVE: We aimed to analyze the association between morphine and in-hospital outcomes in invasively managed ST elevation myocardial infarction (STEMI) and non-ST elevation acute coronary syndrome (NSTE-ACS) patients. BACKGROUND: Morphine is commonly used for analgesia in the setting of acute coronary syndromes (ACS); however, recently its utility in ACS has come under closer scrutiny. METHODS: We identified all STEMI and NSTE-ACS patients undergoing coronary angiogram +/- percutaneous intervention between January 2009 and July 2016 in our center and recorded patient characteristics and inpatient outcomes...

For a given gene, different mutations influence organismal phenotypes to varying degrees. However, the expressivity of these variants not only depends on the DNA lesion associated with the mutation, but also on factors including the genetic background and rearing environment. The degree to which these factors influence related alleles, genes, or pathways similarly, and whether similar developmental mechanisms underlie variation in the expressivity of a single allele across conditions and among alleles is poorly understood...

An effective and sensitive method for the analysis of 1,4-dioxane in water has been available since 2008 (EPA 522). This method is increasingly being applied to investigate the distribution of 1,4-dioxane in the aquatic environment. However, there is a need for more information about the possible occurrence of 1,4-dioxane in groundwater in Europe in general, and in Germany in particular, where virtually no data have been collected so far. The possible contamination of groundwater with 1,4-dioxane is of relevance to Germany because up to 70% of Germany's drinking water is obtained from groundwater and about 17% from river bank filtrate, which contains variable proportions of groundwater...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is an alternative for surgically inoperable patients with severe aortic stenosis. Advanced kidney disease may significantly affect outcomes in patients treated with TAVR and surgical aortic valve replacement (SAVR). HYPOTHESIS: TAVR is associated with better in-hospital outcomes compared with SAVR in patients with advanced kidney disease. METHODS: We identified our sample from the National Inpatient Sample between 2012 and 2014, using International Classification of Diseases, Ninth Revision, Clinical Modification codes...

PURPOSE: More primary care physicians are needed in underserved areas of the United States. Prior research indicates that medical student experiences in underserved settings increase the likelihood they will practice in underserved areas; few studies have controlled for selection bias. This study aimed to estimate the effect of the University of Washington School of Medicine's (UWSOM's) longitudinal extracurricular experience, the Underserved Pathway (UP), on graduates' choice in entering a family medicine residency with underserved training opportunities...

A 27-year-old man with stage IV-B Hodgkin's lymphoma status post autologous peripheral stem cell transplant in 2015 with complete response, presented in 2017 with increasing back pain. Restaging contrast enhanced CT demonstrated left brachiocephalic vein occlusion with peripheral nodular high density areas within C7-T2 vertebral bodies with corresponding radiotracer uptake on same day PET/CT. No matching lesion was seen on noncontrast CT. Findings were consistent with pooling of contrast and radiotracer within vertebral venous plexus collaterals at the cervicothoracic junction secondary to brachiocephalic vein occlusion...

BACKGROUND: Questions persist regarding the general applicability of the Furlow palatoplasty technique, and thus, widespread adoption of its use has been uneven. This study describes a consecutive, nonselective series of primary Furlow palatoplasties. Highlighted is the unique fact that plastic surgical residents functioned as the primary surgeon for all steps of all procedures throughout the series. METHODS: A retrospective review was undertaken of all primary palatoplasties performed under the direction of the senior surgeon between December 2005 and April 2012...

Recent work shows that race is a critical factor in shaping sexual identities, partner preference, and family formation, suggesting there may be racial differences in whether lesbians already have children at the time that they look for companions. In this study, we draw on a sample of 1,923 lesbians on Match.com to quantitatively test whether there are racial differences in dating preferences for women with children, underscoring implications for family inequality through racial differences in who has children when looking for a partner...

Viktor Nilsson-Örtman, Frank Johansson
How the ability to acclimate will impact individual performance and ecological interactions under climate change remains poorly understood. Theory predicts that the benefit an organism can gain from acclimating depends on the rate at which temperatures change relative to the time it takes to induce beneficial acclimation. Here, we present a conceptual model showing how slower seasonal changes under climate change can alter species' relative performance when they differ in acclimation rate and magnitude. To test predictions from theory, we performed a microcosm experiment where we reared a mid- and a high-latitude damselfly species alone or together under the rapid seasonality currently experienced at 62°N and the slower seasonality predicted for this latitude under climate change and measured larval growth and survival...

Many natural populations exhibit temporal fluctuations in abundance that are consistent with external forcing by a randomly changing environment. As fitness emerges from an interaction between the phenotype and the environment, such demographic fluctuations probably include a substantial contribution from fluctuating phenotypic selection. We study the stochastic population dynamics of a population exposed to random (plus possibly directional) changes in the optimum phenotype for a quantitative trait that evolves in response to this moving optimum...

Silicon represents a common intrinsic impurity in graphene, bonding to either three or four carbon neighbors, respectively, in a single or double carbon vacancy. We investigate the effect of the latter defect (Si-C4) on the structural and electronic properties of graphene using density functional theory. Calculations based both on molecular models and with periodic boundary conditions have been performed. The two-carbon vacancy was constructed from pyrene (pyrene-2C) which was then expanded to circumpyrene-2C...
