Abstract

Background

Randomized control trials (RCTs) stopped early for benefit (truncated RCTs) are increasingly common and, on average, overestimate the relative magnitude of benefit by approximately 30%. Investigators stop trials early when they consider it is no longer ethical to enroll patients in a control group. The goal of this systematic review is to determine how investigators of ongoing or planned RCTs respond to the publication of a truncated RCT addressing a similar question.

Methods/design

We will conduct systematic reviews to update the searches of 210 truncated RCTs to identify similar trials ongoing at the time of publication, or started …

Abstract

Background

Previous whole-genome shotgun bisulfite sequencing experiments showed that DNA cytosine methylation in the honey bee (Apis mellifera) is almost exclusively at CG dinucleotides in exons. However, the most commonly used method, bisulfite sequencing, cannot distinguish 5-methylcytosine from 5-hydroxymethylcytosine, an oxidized form of 5-methylcytosine that is catalyzed by the TET family of dioxygenases. Furthermore, some analysis software programs under-represent non-CG DNA methylation and hydryoxymethylation for a variety of reasons. Therefore, we used an unbiased analysis of bisulfite sequencing data combined with molecular and bioinformatics approaches to distinguish 5-methylcytosine from 5-hydroxymethylcytosine. By doing this, we have performed the first whole …

Abstract

Background

Black men have the greatest burden of premature death and disability from hypertension (HTN) in the United States, and the highest incidence and mortality from colorectal cancer (CRC). While several clinical trials have reported beneficial effects of lifestyle changes on blood pressure (BP) reduction, and improved CRC screening with patient navigation (PN), the effectiveness of these approaches in community-based settings remains understudied, particularly among Black men.

Methods/design

MISTER B is a two-parallel-arm randomized controlled trial that will compare the effect of a motivational interviewing tailored lifestyle intervention (MINT) versus a culturally targeted PN intervention on improvement of BP …

Abstract

Background

Residence near municipal solid waste incinerators, a major historical source of dioxin emissions, has been associated with increased risk of non-Hodgkin lymphoma (NHL) in European studies. The aim of our study was to evaluate residence near industrial combustion facilities and estimates of dioxin emissions in relation to NHL risk in the United States.

Methods

We conducted a population-based case–control study of NHL (1998–2000) in four National Cancer Institute-Surveillance Epidemiology and End Results centers (Detroit, Iowa, Los Angeles, Seattle). Residential histories 15 years before diagnosis (similar date for controls) were linked to an Environmental Protection Agency database of dioxin-emitting …


Functional Characterization Of The Cholera Toxin Promoter Of Vibrio Cholerae, Jennifer Dittmer Jan 2013

Functional Characterization Of The Cholera Toxin Promoter Of Vibrio Cholerae, Jennifer Dittmer

Wayne State University Dissertations

Vibrio cholerae is the bacterium responsible for the severe diarrheal disease cholera. The disease is directly caused by cholera toxin, which is secreted by the bacterium in the upper small intestinal lumen during the course of infection. Expression of cholera toxin, along with other virulence genes, is activated by the positive transcriptional regulator, ToxT. ToxT binds to DNA sequences known as toxboxes that are found within promoters of virulence genes and subsequently ToxT activates transcription. However, the toxboxes have not been previously characterized in arguably the most important virulence promoter in V. cholerae, the cholera toxin promoter (PctxAB). …

Biochemical, Structural, And Drug Design Studies Of Multi-Drug Resistant Hiv-1 Therapeutic Targets, Tamaria Grace Dewdney Jan 2013

Biochemical, Structural, And Drug Design Studies Of Multi-Drug Resistant Hiv-1 Therapeutic Targets, Tamaria Grace Dewdney

Wayne State University Dissertations

Protein point mutations acquired as a mechanism of survival against therapeutics cause structural changes that effect protein function and inhibitor binding. This work investigates the structural mechanisms that lead to multi-drug resistance to HIV-1 protease and integrase inhibitors.

Proper proteolytic processing of the HIV-1 Gag/Pol polyprotein is required for HIV infection and viral replication. This feature has made HIV-1 protease an attractive target for antiretroviral drug design for the treatment of HIV-1 infected patients, thus the development of drug resistance has arisen as a major therapeutic and drug design challenge. To understand the molecular mechanisms leading to drug resistance we …

The authors suggest …


Further Reflections On Extinguishing The Fountainhead Of Knowledge: A Call To Transition To The "Innovation Policy" Narrative In Patent Law, Simone Rose Jan 2013

Further Reflections On Extinguishing The Fountainhead Of Knowledge: A Call To Transition To The "Innovation Policy" Narrative In Patent Law, Simone Rose

SMU Law Review

Economists are unable to provide a clear answer to how effective the patent system is in encouraging innovation. At best, they point to certain sectors, such as pharmaceutical and biotechnology, which benefit from a robust patent scheme. Conversely, sectors such as software and, ironically at the same time, biotechnology may be harmed by an overly broad patent scheme. The question emerges: Why do the various stakeholders in all industrial sectors, Congress, the Patent and Trademark Office ("PTO"), and the courts (in particular, the Federal Circuit) continue to center the development of patent law around the "innovation presumption" despite the lack …

Designing Your Home For Maximum Natural Lighting, P. Bytheway, Roslynn Brain

Environment and Society Faculty Publications

There are many benefits to having more natural light in your home. The most obvious of these are the savings you can achieve with a reduced utility bill. According to the U.S. Department of Energy (2012), about 10% of household electricity usage comes from lighting. The more natural light you have in your house, the less lights you have to turn on, and the less electricity you use. Another benefit, also related to energy use, is natural light can help heat homes. One of the best reasons to design your home for natural light involves the health benefits gained through …

Uintah Basin Revisited - 2012-2013 Bioregional Planning Studio Project, Richard E. Toth, Matthew Coombs, C Michael Gottfredson, Tyler Allen

Environment and Society Faculty Publications

Since the Uintah Basin Research Conference in 2007, residents of the area have witnessed a consistent level of land-use development throughout the region. Portions of that growth and development have precipitated the need to develop a landscape-level plan in order to maintain the context of their region and community identity in the coming years. The purpose of this study is to research and develop a process that identifies current and future land-use issues throughout the Uintah Basin. The identification of these issues by various stakeholders will help to provide a framework for future policy decisions.


Continuity Of Cancer Care: Where Do Primary Care Practitioners Fit In?, M Jiwa, A Mcmanus, A Dadich Jan 2013

Continuity Of Cancer Care: Where Do Primary Care Practitioners Fit In?, M Jiwa, A Mcmanus, A Dadich

Medical Papers and Journal Articles

Cancer is the leading cause of illness in Australia and is a national health priority. Primary care in Australia is well positioned to support individuals diagnosed with cancer and their family/caretakers. However, obstacles exist that impact on the quality and continuity of care that primary care providers and community health professionals can provide. A rapid review of the research available revealed that the knowledge, attitudes and beliefs held by health professionals and patients can impact engagement in early detection, treatment and follow-up care. Health professionals have limited knowledge of evidence-based practices, while cancer literacy among minority groups, including Aboriginal Australians, …
