The Significance Of Alternative Techniques In Biomedical Research: An Analysis Of Nobel Prize Awards, Martin Stephens 2016 The Humane Society of the United States

The Significance Of Alternative Techniques In Biomedical Research: An Analysis Of Nobel Prize Awards, Martin Stephens

Martin Stephens, Ph.D.

The "alternatives approach" consists of developing and employing methods specifically designed as alternatives. The aim of the approach is to determine the extent to which alternatives can replace traditional uses of animals. This aim has an ethical and compassionate appeal that is being bolstered by recent scientific advances in developing alternatives (Stephens 1986b).

The importance of alternative methods in the history of biomedical research can be inferred from Nobel Prize awards in medicine or physiology. These awards are generally believed to recognize research "of the highest caliber, the most enduring influence, and the most importance to biomedical science" according to ...


Estimation Of Long-Term Area-Average Pm2.5 Concentrations For Area-Level Health Analyses, Sun-Young Kim, Casey Olives, Neal Fann, Joel Kaufman, Sverre Vedal, Lianne Sheppard 2016 University of Washington - Seattle Campus

Estimation Of Long-Term Area-Average Pm2.5 Concentrations For Area-Level Health Analyses, Sun-Young Kim, Casey Olives, Neal Fann, Joel Kaufman, Sverre Vedal, Lianne Sheppard

UW Biostatistics Working Paper Series

Introduction: There is increasing evidence of an association between individual long-term PM2.5 exposure and human health. Mortality and morbidity data collected at the area-level are valuable resources for investigating corresponding population-level health effects. However, PM2.5 monitoring data are available for limited periods of time and locations, and are not adequate for estimating area-level concentrations. We developed a general approach to estimate county-average concentrations representative of population exposures for 1980-2010 in the continental U.S.

Methods: We predicted annual average PM2.5 concentrations at about 70,000 census tract centroids, using a point prediction model previously ...


Self-Care And Mobility Disability At Mid-Life In Lucky Few, Early-, And Late-Baby Boom Birth-Cohorts, Carlos Siordia 2016 University of Pittsburgh - Main Campus

Self-Care And Mobility Disability At Mid-Life In Lucky Few, Early-, And Late-Baby Boom Birth-Cohorts, Carlos Siordia

Journal of Health Disparities Research and Practice

Disability is related in definite ways with makers of social stratum, as it can be influenced by and has the potential to contribute to the production and reproduction of social stratification. Intersectional markers of social stratification processes are ignored determinants of health. The Class, Race, Sex (CRS) hypothesis presented here argues that a low-education, racial-minority, and female disadvantage will compound to affect the prevalence and risks of disability. The evidence presented validates the CRS hypothesis by showing that disability prevalence and risk clusters first by class, race, and then sex. The cross-sectional study of community-dwelling adults in the Unites States ...


Q-Fever In A Refugee After Exposure To A Central New York State Livestock Farm, Mustafa Qazi, Anita C. Weimer, Brenden Bedard, Byron S. Kennedy 2016 University of Rochester

Q-Fever In A Refugee After Exposure To A Central New York State Livestock Farm, Mustafa Qazi, Anita C. Weimer, Brenden Bedard, Byron S. Kennedy

Health Science Faculty Publications

Q-fever is a zoonotic disease caused by Coxiella burnetii that can create an acute or chronic form of the illness. In March 2014, Q-fever was identified by serology and Real-time Polymerase Chain Reaction (RT-PCR), in a 62 year-old male that was a Nepalese refugee. The male visited a livestock farm with a slaughterhouse in rural Central New York State, twenty-two days prior to onset of symptoms. He had direct handling of goats on this farm prior to slaughter. We describe the case presentation of his illness and the public health epidemiological investigation.

The Association Between Social Cohesion And Physical Activity In Communities Across Canada: A Multilevel Analysis, Calvin Yip

Electronic Thesis and Dissertation Repository

Background: In Canada, only 15% of adults meet physical activity guidelines for optimal health. Previous research has suggested that social cohesion may promote physical activity.

Objective: To assess the association between social cohesion and physical activity among adults aged 18 to 64 years in Canada.

Methods: Data from the 2009-2010, 2011-2012, and 2013-2014 cycles (N=245,150) of the Canadian Community Health Survey were used. Physical activity level was operationalized using average daily energy expenditure, social cohesion was determined by self-rated sense of belonging to the local community, and communities were represented by Canada’s Forward Sortation Areas. Multilevel regression ...

Survival Rates In Trauma Patients Following Health Care Reform In Massachusetts, Turner Osler, Laurent G. Glance, Wenjun Li, Jeffery S. Buzas, David W. Hosmer

Wenjun Li

IMPORTANCE: Massachusetts introduced health care reform (HCR) in 2006, expecting to expand health insurance coverage and improve outcomes. Because traumatic injury is a common acute condition with important health, disability, and economic consequences, examination of the effect of HCR on patients hospitalized following injury may help inform the national HCR debate. OBJECTIVE: To examine the effect of Massachusetts HCR on survival rates of injured patients. DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study of 1,520,599 patients hospitalized following traumatic injury in Massachusetts or New York during the 10 years (2002-2011) surrounding Massachusetts HCR using data from the State Inpatient ...

Multiple Imputation Based Clustering Validation (Miv) For Big Longitudinal Trial Data With Missing Values In Ehealth, Zhaoyang Zhang, Hua (Julia) Fang, Honggang Wang

Quantitative Health Sciences Publications and Presentations

Web-delivered trials are an important component in eHealth services. These trials, mostly behavior-based, generate big heterogeneous data that are longitudinal, high dimensional with missing values. Unsupervised learning methods have been widely applied in this area, however, validating the optimal number of clusters has been challenging. Built upon our multiple imputation (MI) based fuzzy clustering, MIfuzzy, we proposed a new multiple imputation based validation (MIV) framework and corresponding MIV algorithms for clustering big longitudinal eHealth data with missing values, more generally for fuzzy-logic based clustering methods. Specifically, we detect the optimal number of clusters by auto-searching and -synthesizing a suite of ...

Optimizing access to HIV pre-exposure prophylaxis (PrEP), an evidence-based HIV prevention resource, requires expanding healthcare providers' adoption of PrEP into clinical practice. This qualitative study explored PrEP providers' firsthand experiences relative to six commonly-cited barriers to prescription-financial coverage, implementation logistics, eligibility determination, adherence concerns, side effects, and anticipated behavior change (risk compensation)-as well as their recommendations for training PrEP-inexperienced providers. U.S.-based PrEP providers were recruited via direct outreach and referral from colleagues and other participants (2014-2015). One-on-one interviews were conducted in person or by phone, transcribed, and analyzed. The sample (n = 18) primarily practiced in the Northeastern ...

Demographic Profile, Geographic Distribution, Disability Prevalence, And Likelihood Of Being In-Poverty Amongst Grandparents Responsible For Grandchildren, Carlos Siordia, Mary E. Rauktis

GrandFamilies: The Contemporary Journal of Research, Practice and Policy

Evidence-based research on Grandparents Responsible for Grandchildren (GRfG) continues to grow in recent decades. This brief report expands global knowledge on custodial grandparents by making use of a large data resource in the United States (US). The specific aim was to delineate the demographic profile, geographic distribution, and prevalence of specific-disabilities for the GRFG population in the US mainland. We also explore how demographic factors are associated with likelihood of being in-poverty. The analysis used data from the 2009-2013 American Community Survey (ACS) 5-year Public Use Microdata Sample (PUMS) file. The ACS is a nationally representative, yearly, statistical survey administered ...

Race/Sex Group Modification Of The Association Between Allostatic Load And Depression: Findings From The National Health And Nutrition Examination Survey, 2005-2010, Ganga Bey, Sharina D. Person

UMass Center for Clinical and Translational Science Research Retreat

Objective: We assessed whether the relationship between depression and chronic stress as measured in allostatic load (AL) differs by race and sex among US black and white adults.

Methods: Using data from the National Health and Nutrition Examination Survey (NHANES) 2005-2010, we examined race/sex modification of the relationship between AL and depression in black and white women and men aged 18-64 years (n=6431). AL scores, ranging from 0-9, were calculated using 9 cardiovascular, metabolic, and immunologic biomarkers; scores ≥ 4 were considered “high-risk”. Depression was assessed using the PHQ-9; scores ≥ 10 indicate clinical depression. Logistic regression models estimated odds ...

UMass Center for Clinical and Translational Science Research Retreat

BACKGROUND: Obesity prevention has become a major focus of public health efforts in the United States. The Federal Government set forth national nutrition and physical activity recommendations to prevent obesity and promote well-being among children. A succinct message developed through a program in Maine “Let’s Go! 5-2-1-0” summarizes these obesity prevention behaviors including ≥5 fruit and vegetables, ≤2 hours of screen time, ≥1 hour of physical activity, and 0 sugar sweetened beverages daily. The study evaluates racial/ethnic disparities among adolescents meeting the 5-2-1-0 targets in a nationally representative sample.

METHODS: The 2011-2012 NHANES dataset was used to conduct ...


Sedentary Behavior And Cardiovascular Disease Risk Factors Among Latino Adults, Valerie J. Silfee, Stephenie C. Lemon, Vilma Lora, Milagros C. Rosal 2016 University of Massachusetts Medical School

Sedentary Behavior And Cardiovascular Disease Risk Factors Among Latino Adults, Valerie J. Silfee, Stephenie C. Lemon, Vilma Lora, Milagros C. Rosal

UMass Center for Clinical and Translational Science Research Retreat

Background: Compared to other racial/ethnic subgroups in the U.S., Latinos experience increased rates of cardiovascular disease (CVD) and CVD risk factors such as hypertension, inactivity, and diabetes. Sedentary behavior has also been defined as an additional risk factor for CVD, independent of physical activity participation. However, while sedentary behavior has been associated with increased risk for CVD among primarily White samples, previous studies in Latinos have shown mixed results.

Purpose: To explore the relationships between sedentary behavior and CVD risk factors, including BMI, waist circumference, blood pressure, physical activity, dyslipidemia, and diabetes, among a sample of Latino adults ...


Angina Characteristics As Predictors Of Trajectories Of Quality Of Life Following Acute Coronary Syndrome In The Transitions, Risks And Actions In Coronary Events-Center For Outcomes Research And Education Cohort (Trace-Core), Lisa Nobel, Jennifer Tjia, Jane S.

Angina Characteristics As Predictors Of Trajectories Of Quality Of Life Following Acute Coronary Syndrome In The Transitions, Risks And Actions In Coronary Events-Center For Outcomes Research And Education Cohort (Trace-Core), Lisa Nobel, Jennifer Tjia, Jane S. Saczynski, Molly E. Waring, Milena D. Anatchkova, Arlene Ash, Catarina I. Kiefe, Jeroan Allison

UMass Center for Clinical and Translational Science Research Retreat

BACKGROUND: To describe longitudinal trajectories of health-related quality of life (HRQoL) after hospitalization with an acute coronary syndrome (ACS), their associations with baseline angina characteristics, and associations with anxiety, depression, and cognitive impairment.

METHODS: TRACE-CORE participants (N=1,613) completed the SF-36 during hospitalization for ACS and 1, 3, & 6 months post-discharge. Latent growth curves identified trajectories of physical and mental components of HRQOL (MCS and PCS) and sequential multiple logistic regression estimated associations between trajectories and angina characteristics.

RESULTS: Participants (N=1613) had mean age 63.3 (SD 11.4) years, 33.0% female, and 78.2% non-Hispanic white. We identified 2 MCS trajectories: AVERAGE and IMPAIRED HRQoL. The majority of participants (81.0%) had AVERAGE MCS at baseline (mean MCS 53.6) and slight improvement in scores over time. A minority (19.0%) had IMPAIRED HRQoL at baseline (mean MCS 36.7) and slight improvement in scores over time. We identified 2 similar PCS trajectories with similar patterns of scores over time: AVERAGE (71.1%) and IMPAIRED (28.9%) HRQoL at baseline. Adjusting for demographics & comorbidities, patients with less severe baseline angina were more likely to have AVERAGE MCS (odds ratio [OR]/10 unit change in severity 1.1) and PCS (OR 1.1) trajectories, and similarly for less frequent angina (MCS OR 1.2; PCS OR 1.3). The associations of MCS trajectory with severity and frequency lost significance after adjusting for psychosocial factors, whereas the PCS associations remained significant [All p < 0.05 unless noted].

CONCLUSIONS: About 1/3 of patients exhibited impaired 6-month HRQoL trajectories, which can be predicted by angina characteristics. Psychosocial factors may explain the ...
