BACKGROUND: Recurrent/metastatic adenoid cystic carcinoma (ACC) is an incurable disease with no standard treatments. The majority of ACCs express the oncogenic transcription factor MYB (also c-myb), often in the context of a MYB gene rearrangement. This phase II trial of the tyrosine kinase inhibitor (TKI) axitinib (Pfizer) tested the hypothesis that targeting pathways activated by MYB can be therapeutically effective for ACC. PATIENTS AND METHODS: This is a minimax two-stage, phase II trial that enrolled patients with incurable ACC of any primary site...

BACKGROUND: Surgical site infections (SSI) increase morbidity and mortality, hospital costs, length of stay, readmissions, and risk of litigation and may impact a facility's reputation. METHODS: Through implementation of a Six Sigma, interdisciplinary team process and the Contextual Model for change engaged all stakeholders. A total of 44 perioperative processes were evaluated, with 15 processes ultimately altered. Revisions involved identifying inconsistent implementation of procedures and standardizing processes, as well as utilizing new suture techniques and products including disposable electrocardiogram leads and pacing wires, antibiotic-coated sutures, and silver-impregnated midsternal dressings...

The goal was to estimate the heritabilities and genetic variances for pregnancy rate (PR) and calving date (CD) in Angus cattle along with the effect of weight, age, and sire on PR and CD. The data consisted of 4,999 records on PR and CD. Statistical models included year as a fixed effect; premating/postmating weight and age as covariates; and sire of embryo, maternal grandsire (MGS), and permanent maternal environmental effects as random effects. The models also included the interactions between herd and weight (weight change)...

Consumption of alcohol during pregnancy can have detrimental impacts on the developing hippocampus, which can lead to deficits in learning and memory function. Although high levels of alcohol exposure can lead to severe deficits, there is a lack of research examining the effects of low levels of exposure. This study used a rat model to determine if prenatal exposure to chronic low dose ethanol would result in deficits in learning and memory performance and if this was associated with morphological changes within the hippocampus...

Adults with schizophrenia present cognitive impairments, as do individuals at ultra-high risk for the disorder, youth with relatives with schizophrenia spectrum disorders, and children with antecedents of schizophrenia. The present study aimed to determine if impairments in childhood differed depending on the definition of risk and/or on the degree of relatedness to an affected individual, and if impairments were explained by IQ. Four groups of children aged 9-12 years were studied: (1) 13 children with ≥1 first-degree or ≥2 second-degree affected relatives (high familial loading: FHx(H)); (2) 14 with ≥1 affected second-degree relative (lower familial loading: FHx(L)); (3) 32 with well-replicated antecedents of schizophrenia (ASz); and (4) 45 typically-developing (TD) children with neither a positive family history nor antecedents...

Beef with yellow fat is considered undesirable by consumers in most European and Asian markets. β-Carotene is the major carotenoid deposited in the adipose tissue and milk fat of cattle (Bos taurus), which can result in the yellowness. The effects of retinal short-chain dehydrogenase reductase (RDHE2) and β, β-carotene 9',10-dioxygenase (BCO2) were considered jointly as major candidate genes for causing the yellow fat colour, based on their genomic locations in the fat colour quantitative trait loci (QTL) and their roles in the metabolism of β-carotene...

OBJECTIVE: : Application of off-pump techniques to reoperative coronary artery bypass (redo CABG) has been limited by technical difficulty and potential for embolism of atheromatous debris from diseased grafts, resulting in myocardial infarction and rapid hemodynamic deterioration. We compared outcomes after off-pump (OPCAB) and on-pump (ONCAB) in redo CABG. METHODS: : A retrospective chart review was performed for patients who underwent redo CABG at a single academic institution between January 1997 and December 2004...

BACKGROUND: Inflammation is a cardinal feature of migraines. A number of observations point to the possibility that an allergic component of a type I (IgE-mediated) nature may be involved in at least some migraineurs. Not only are migraines frequent among patients with allergic rhinitis but quite frequently the same medical approaches are beneficial in both diseases: anti-inflammatories, adrenergic tone modifiers, immune suppressants. The effect that immunotherapy for allergic rhinitis has upon migraines is studied...

A whole-genome scan was carried out in New Zealand and Australia to detect quantitative trait loci (QTL) for live animal and carcass composition traits and meat quality attributes in cattle. Backcross calves (385 heifers and 398 steers) were generated, with Jersey and Limousin backgrounds. The New Zealand cattle were reared and finished on pasture, whilst Australian cattle were reared on grass and finished on grain for at least 180 days. This paper reports on meat quality traits (tenderness measured as shear force at 4-5 ages on two muscles as well as associated traits of meat colour, pH and cooking loss) and a number of metabolic traits...

BACKGROUND: The impact of the degrees of renal dysfunction (RD) after aortic valve replacement (AVR) has not been well described. The purpose of this study was to compare patients undergoing AVR with a range of renal function from normal to dialysis-dependence. METHODS: A retrospective review of 2,408 patients undergoing AVR with or without coronary artery bypass graft surgery (CABG) from January 1996 to March 2009 was performed. Glomerular filtration rate (GFR) was estimated for patients using the Modification of Diet in Renal Disease formula...

BACKGROUND: We previously developed a novel method of identifying children aged 9-12 years who may be at elevated risk of developing schizophrenia and the spectrum disorders because they present a triad of putative antecedents of schizophrenia (ASz). The present study aimed to determine whether ASz children also present neurocognitive deficits that are commonly observed in patients with schizophrenia. METHODS: Twenty-eight ASz children and 28 typically-developing (TD) children without the antecedents of schizophrenia completed a battery of neurocognitive tests assessing seven domains of function: General intelligence, scholastic achievement, verbal memory, visual memory, working memory, executive function (EF)-verbal fluency, and EF-inhibition...

A QTL study of live animal and carcass traits in beef cattle was carried out in New Zealand and Australia. Back-cross calves (385 heifers and 398 steers) were generated, with Jersey and Limousin backgrounds. This paper reports on weights of eight organs (heart, liver, lungs, kidneys, spleen, gastro-intestinal tract, fat, and rumen contents) and 12 fat composition traits (fatty acid (FA) percentages, saturated and monounsaturated FA subtotals, and fat melting point). The New Zealand cattle were reared and finished on pasture, whilst Australian cattle were reared on grass and finished on grain for at least 180 days...

beta, beta-carotene-9', 10'-dioxygenase (BCO2) plays a role in cleaving beta-carotene eccentrically, and may be involved in the control of adipose and milk colour in cattle. The bovine BCO2 gene was sequenced as a potential candidate gene for a beef fat colour QTL on chromosome (BTA) 15. A single nucleotide base change located in exon 3 causes the substitution of a stop codon (encoded by the A allele) for tryptophan(80) (encoded by the G allele) (c. 240G>A, p.Trp80stop, referred to herein as SNP W80X). Association analysis showed significant differences in subcutaneous fat colour and beta-carotene concentration amongst cattle with different BCO2 genotypes...

The incidence of penetrating trauma to the brachiocephalic artery and aortic arch is not known, because most patients die of hemorrhage before they receive adequate treatment. Furthermore, when torrential hemorrhage from penetrating trauma is present, the anatomy of the thoracic vasculature can present a challenge for gaining adequate exposure, achieving vascular control, and performing proper repair. We describe the case of a patient with a gunshot wound to the anterior chest; he was placed under cardiopulmonary bypass and deep hypothermic circulatory arrest while we performed a patch repair of the proximal brachiocephalic artery and aortic arch...

BACKGROUND: Race has been shown to be an independent risk factor for operative mortality after coronary artery bypass grafting (CABG). This study sought to determine the extent to which race is a risk factor for adverse events, long-term mortality, and whether off-pump surgery (OPCAB) modifies that risk. METHODS AND RESULTS: The Society of Thoracic Surgeons Adult Cardiac Database at Emory Healthcare affiliated hospitals was queried for all primary isolated CABG records from 1997 to 2007...
