PURPOSE: We surveyed a national sample of nonacademic physicians who ordered BRCA1/2 testing to understand their implementation of genetic testing and to assess recommendations for surveillance and cancer risk management of women with positive test results.

PATIENTS AND METHODS: We surveyed physicians (N = 611 of 1,050; response rate, 58.2%) practicing in nonacademic settings who ordered BRCA1/2 testing during 2004 to 2005. We described physicians' experiences with testing and used multivariable regression models to identify factors associated with more complete counseling and with recommendations for cancer risk management for a BRCA1 mutation carrier.

RESULTS: Most physicians (68.2%) usually or always …


Improved Feed Protein Fractionation Schemes For Formulating Rations With The Cornell Net Carbohydrate And Protein System, Cristina Lanzas, G A. Broderick, D G. Fox Dec 2008

Improved Feed Protein Fractionation Schemes For Formulating Rations With The Cornell Net Carbohydrate And Protein System, Cristina Lanzas, G A. Broderick, D G. Fox

Cristina Lanzas

Adequate predictions of rumen-degradable protein (RDP) and rumen-undegradable protein (RUP) supplies are necessary to optimize performance while minimizing losses of excess nitrogen (N). The objectives of this study were to evaluate the original Cornell Net Carbohydrate Protein System (CNCPS) protein fractionation scheme and to develop and evaluate alternatives designed to improve its adequacy in predicting RDP and RUP. The CNCPS version 5 fractionates CP into 5 fractions based on solubility in protein precipitant agents, buffers, and detergent solutions: A represents the soluble nonprotein N, B1 is the soluble true protein, B2 represents protein with intermediate rates of degradation, B3 is …

Cristina Lanzas

The objective of this study was to address the impact of heterogeneity of infectious period and contagiousness on Salmonella transmission dynamics in dairy cattle populations. We developed three deterministic SIR-type models with two basic infected stages (clinically and subclinically infected). In addition, model 2 included long-term shedders, which were defined as individuals with low contagiousness but long infectious period, and model 3 included super-shedders (individuals with high contagiousness and long infectious period). The simulated dynamics, basic reproduction number (R0) and critical vaccination threshold were studied. Clinically infected individuals were the main force of infection transmission for models 1 and 2. …


The Risk And Control Of Salmonella Outbreaks In Calf-Raising Operations: A Mathematical Modeling Approach, Cristina Lanzas, L D. Warnick, R Ivanek, P Ayscue, D V. Nydam, Y T. Grohn Nov 2008

The Risk And Control Of Salmonella Outbreaks In Calf-Raising Operations: A Mathematical Modeling Approach, Cristina Lanzas, L D. Warnick, R Ivanek, P Ayscue, D V. Nydam, Y T. Grohn

Cristina Lanzas

Salmonellosis in calves has economic and welfare implications, and serves as a potential source of human infections. Our objectives were to assess the risk of Salmonella spread following its introduction into a herd of pre-weaned calves and to evaluate the efficacy of control strategies to prevent and control outbreaks. To meet these objectives, we developed a model of Salmonella transmission within a pre-weaned group of calves based on a well documented outbreak of salmonellosis in a calf-raising operation and other literature. Intervention scenarios were evaluated in both deterministic and stochastic versions of the model. While the basic reproduction number (R0) …

Influenza Genetic Sequence Patents: Where Intellectual Property Clashes With Public Health Needs, Lori B. Andrews, Laura A. Shackelton Apr 2008

Influenza Genetic Sequence Patents: Where Intellectual Property Clashes With Public Health Needs, Lori B. Andrews, Laura A. Shackelton

Lori B. Andrews

A number of advances have recently taken place in influenza virus genomics research, due largely to an extensive genome sequencing project and widespread access to these sequences. If a pandemic virus emerges, whether it is a reassorted A/H5N1 strain or another zoonosis, it is essential that access to information about its genetic sequence is not restricted through intellectual property claims. Products of nature are not patentable inventions, according to US code and the US Supreme Court, and naturally occurring genetic sequences should not be eligible for patenting. Viral genetic sequences represent natural information upon which diagnostics and preventions are necessarily …


Gene Alterations By Peroxisome Proliferator-Activated Receptor Gamma Agonists In Human Colorectal Cancer Cells, Maria Cekanova, J Yuan, X Li, K B. Kim, Seung J. Baek Apr 2008

Gene Alterations By Peroxisome Proliferator-Activated Receptor Gamma Agonists In Human Colorectal Cancer Cells, Maria Cekanova, J Yuan, X Li, K B. Kim, Seung J. Baek

Maria Cekanova MS, RNDr, PhD

The peroxisome proliferator-activated receptor gamma (PPARgamma) is a nuclear transcription factor that controls the genes involved in metabolism and carcinogenesis. In the present study, we examined the alteration of gene expression in HCT-116 human colorectal cancer cells by PPARgamma agonists: MCC-555 (5 microM), rosiglitazone (5 microM), and 15-deoxy-Delta12,14-prostaglandin J2 (1 microM). The long-oligo microarray data revealed a list of target genes commonly induced (307 genes) and repressed (32 genes) by tested PPARgamma agonists. These genes were analyzed by Onto-Express software and KEGG pathway analysis and revealed that PPARgamma agonists are involved in cell proliferation, focal adhesion, and several signaling pathways. …


Myocardial Infarction And Heart Failure Hospitalization Rates In Maine, Usa – Variability Along The Urban-Rural Continuum, David E. Harris, A. M. Aboueissa, David Hartley Mar 2008

Myocardial Infarction And Heart Failure Hospitalization Rates In Maine, Usa – Variability Along The Urban-Rural Continuum, David E. Harris, A. M. Aboueissa, David Hartley

David Hartley

Cardiovascular disease, including myocardial infarction (MI) and heart failure (HF), remains the leading cause of death in wealthy countries and is of increasing concern in low- and middle-income countries as risk factors such as smoking and obesity become more common around the globe. Within each country the health burden of MI and HF generally falls more heavily on those who live in rural areas and on those who live in communities with lower average socioeconomic status (SES). Hospitalization rates are an important measure of community health because high rates may indicate a high burden of poor health, while inappropriately low …

Measuring The Dynamic Surface Accessibility Of Rna With The Small Paramagnetic Molecule Tempol, Vincenzo Venditti, Neri Niccolai, Samuel E. Butcher Jan 2008

Measuring The Dynamic Surface Accessibility Of Rna With The Small Paramagnetic Molecule Tempol, Vincenzo Venditti, Neri Niccolai, Samuel E. Butcher

Vincenzo Venditti

The surface accessibility of macromolecules plays a key role in modulating molecular recognition events. RNA is a complex and dynamic molecule involved in many aspects of gene expression. However, there are few experimental methods available to measure the accessible surface of RNA. Here, we investigate the accessible surface of RNA using NMR and the small paramagnetic molecule TEMPOL. We investigated two RNAs with known structures, one that is extremely stable and one that is dynamic. For helical regions, the TEMPOL probing data correlate well with the predicted RNA surface, and the method is able to distinguish subtle variations in atom …


Invited Review: Heat Shock Proteins And Exercise: A Primer, Earl Noble, Kevin Milne, C.W. Melling Dec 2007

Invited Review: Heat Shock Proteins And Exercise: A Primer, Earl Noble, Kevin Milne, C.W. Melling

Jamie Melling

Heat shock proteins (HSPs) are, in general, prosurvival molecules within the cellular environment, and the overexpression of even just 1 family of HSPs can lead to protection against and improvements after a variety of stressors. Not surprisingly, a fertile area of study has grown out of effors to exploit the innate biologic behaviour of HSPs. Exercise, because of the inherent physiologic stresses associated with it, is but 1 stimulus that can result in a robust increase in various HSPs in several tissues, not the least of which happen to be the heart and skeletal muscle. The purpose of this review …

Childhood Sexual Abuse In Black Men Who Have Sex With Men: Results From Three Qualitative Studies, Sheldon D. Fields, David J. Malebranche, Sonja Feist-Price Dec 2007

Childhood Sexual Abuse In Black Men Who Have Sex With Men: Results From Three Qualitative Studies, Sheldon D. Fields, David J. Malebranche, Sonja Feist-Price

David J Malebranche

This report describes the high prevalence and context of childhood sexual abuse (CSA) among Black men who have sex with men (MSM) across 3 independent qualitative studies. Semistructured one-on-one interviews were conducted with 87 Black MSM across 3 cities (Rochester, NY, n=28; Lexington, KY/Atlanta, GA, n=30; and Atlanta, GA, n =29). A combined CSA prevalence of 32% (28/87) was found among the 3 samples, despite variation in geographic location, mean age, and sexual identification. Common themes emerging across the 3 samples included prolonged and repeated abuse by a close male relative; blaming of same-sex desire on CSA; and descriptions of …


Bisexually Active Black Men In The United States And Hiv: Acknowledging More Than The "Down Low", David J. Malebranche Dec 2007

Bisexually Active Black Men In The United States And Hiv: Acknowledging More Than The "Down Low", David J. Malebranche

David J Malebranche

HIV is disproportionately impacting Black men who have sex with men and heterosexual women in theUnited States. Current speculation posits a ‘‘bisexual bridge’’ of HIV transmission connecting these two subpopulations of the Black community. Specifically, bisexually active Black men who identify as heterosexual but do not disclose their same-sex behavior, or ‘‘down low’’ (DL) men, have received the most attention and blame as the primary group fueling this epidemic. This essay explores the current knowledge and limitations of public health research on bisexually active Black men. Implications for future research initiatives are discussed.
