Composing with Light and Color: Storytelling Through Art and Science

Composing with Color and Light: Storytelling through Art and Science is an exploration of all of theatrical productions that I designed within the Master of Fine Arts program at the University of South Carolina, with a concentration in Lighting Design and focuses on the design process from beginning to end. Each production had its own set of challenges and lessons that have prepared me for more professional design opportunities as my career expands around the world. Each University of South Carolina production presented specific and unique challenges. From paperwork, to learning and understanding how to communicate with a team and knowing that theatre is a collaborative job

Hazardous Drinking Prevalence and Correlates in Older New Zealanders: A Comparison of the AUDIT-C and the CARET

Objectives: The study compared the proportion of older adults identified as drinking hazardously based on the Alcohol Use Disorders Identification Test–Consumption (AUDIT-C) with the older adult-specific Comorbidity Alcohol Risk Evaluation Tool (CARET) and investigated whether sociodemographics, comorbidities, health, medication use, and alcohol-related risk behaviors explained discrepancies between the screens in classification of hazardousness. Method: The AUDIT-C and the CARET were administered to 3,673 adults aged 55 to 89 years. Classification agreement between the screens was evaluated using Cohen’s kappa. Hazardous drinking groups were compared using logistic regression. Results: Analysis indicated moderate agreement between the screens. Drinkers classified as “hazardous on the CARET only” consumed less alcohol, but were more likely to drink-drive. Introducing a drink-driving criterion into the calculation of hazardousness on the AUDIT-C substantially decreased the classification discrepancy between the measures. Discussion: Standard screening can be improved by investigating comorbidities, medication use, and alcohol-related risk behaviors in those initially identified as nonhazardous drinkers

Fine-mapping of prostate cancer susceptibility loci in a large meta-analysis identifies candidate causal variants

Prostate cancer is a polygenic disease with a large heritable component. A number of common, low-penetrance prostate cancer risk loci have been identified through GWAS. Here we apply the Bayesian multivariate variable selection algorithm JAM to fine-map 84 prostate cancer susceptibility loci, using summary data from a large European ancestry meta-analysis. We observe evidence for multiple independent signals at 12 regions and 99 risk signals overall. Only 15 original GWAS tag SNPs remain among the catalogue of candidate variants identified; the remainder are replaced by more likely candidates. Biological annotation of our credible set of variants indicates significant enrichment within promoter and enhancer elements, and transcription factor-binding sites, including AR, ERG and FOXA1. In 40 regions at least one variant is colocalised with an eQTL in prostate cancer tissue. The refined set of candidate variants substantially increase the proportion of familial relative risk explained by these known susceptibility regions, which highlights the importance of fine-mapping studies and has implications for clinical risk profiling. © 2018 The Author(s).Prostate cancer is a polygenic disease with a large heritable component.

Psychosocial impact of undergoing prostate cancer screening for men with BRCA1 or BRCA2 mutations.

OBJECTIVES: To report the baseline results of a longitudinal psychosocial study that forms part of the IMPACT study, a multi-national investigation of targeted prostate cancer (PCa) screening among men with a known pathogenic germline mutation in the BRCA1 or BRCA2 genes. PARTICPANTS AND METHODS: Men enrolled in the IMPACT study were invited to complete a questionnaire at collaborating sites prior to each annual screening visit. The questionnaire included sociodemographic characteristics and the following measures: the Hospital Anxiety and Depression Scale (HADS), Impact of Event Scale (IES), 36-item short-form health survey (SF-36), Memorial Anxiety Scale for Prostate Cancer, Cancer Worry Scale-Revised, risk perception and knowledge. The results of the baseline questionnaire are presented. RESULTS: A total of 432 men completed questionnaires: 98 and 160 had mutations in BRCA1 and BRCA2 genes, respectively, and 174 were controls (familial mutation negative). Participants' perception of PCa risk was influenced by genetic status. Knowledge levels were high and unrelated to genetic status. Mean scores for the HADS and SF-36 were within reported general population norms and mean IES scores were within normal range. IES mean intrusion and avoidance scores were significantly higher in BRCA1/BRCA2 carriers than in controls and were higher in men with increased PCa risk perception. At the multivariate level, risk perception contributed more significantly to variance in IES scores than genetic status. CONCLUSION: This is the first study to report the psychosocial profile of men with BRCA1/BRCA2 mutations undergoing PCa screening. No clinically concerning levels of general or cancer-specific distress or poor quality of life were detected in the cohort as a whole. A small subset of participants reported higher levels of distress, suggesting the need for healthcare professionals offering PCa screening to identify these risk factors and offer additional information and support to men seeking PCa screening

Thigh-length compression stockings and DVT after stroke

Controversy exists as to whether neoadjuvant chemotherapy improves survival in patients with invasive bladder cancer, despite randomised controlled trials of more than 3000 patients. We undertook a systematic review and meta-analysis to assess the effect of such treatment on survival in patients with this disease

Blood-brain equilibration kinetics of levo-alpha-acetyl-methadol using a chronically instrumented sheep preparation

© 2006 British Pharmacological SocietyThe delayed onset and long duration of action of the opioid agonist levo--acetyl-methadol (LAAM) has been attributed to the formation of active metabolites. However, at present, little is known about the time course of blood–brain equilibration of LAAM itself. The cerebral kinetics of LAAM were quantified using physiologically based kinetic models and a conscious chronically instrumented sheep preparation. Seven sheep were administered 4 min intravenous infusions of 30 mg LAAM. Concentrations of LAAM and N-demethylated metabolites (nor-LAAM and di-nor-LAAM) in whole blood (0–75 min) were measured using a validated HPLC assay. LAAM did not alter cerebral blood flow, mean arterial pressure or cause significant respiratory depression. Cardiac output was similar to baseline at 4 min, but decreased by 30% at 10 min and remained at this level for the duration of the 75 min study period. Cerebral kinetics were best described by a membrane-limited model, with a relatively slow blood–brain tissue equilibration half-life of 22 min due to intermediate permeability (56 ml min-1) and a large cerebral distribution volume (724 ml). In conclusion, pharmacokinetic–pharmacodynamic modelling of LAAM should account for the large equilibration delay between brain and blood caused by slow equilibration kinetics. This may account for some of the delay in onset of effect previously attributed to the delayed appearance of active metabolites in blood.David J. R. Foster, Mette L. Jensen, Richard N.
