In the largest study to date on phthalates and postmenopausal breast cancer, a University of Massachusetts Amherst cancer epidemiology researcher found no association between breast cancer risk and exposure to the plasticizing and solvent chemicals used in such common products as shampoo, makeup, vinyl flooring, toys, medical devices and car interiors.
In a new study published in the journal Health Economics, researchers at CDDEP, the University of Strathclyde in Scotland, and Wageningen University in the Netherlands developed a mathematical framework to estimate the value of investing in developing and conserving an antibiotic to mitigate the burden of bacterial infections caused by resistant Staphylococcus aureus during a pandemic influenza outbreak.
In the study, 'Obstructive Sleep Apnea and Inflammation: Proof of Concept Based on Two Illustrative Cytokines,' published recently in the International Journal of Molecular Sciences, researchers examined the link between obstructive sleep apnea syndrome (OSAS) and inflammation and the ensuing damage caused to organs. They concluded that OSAS promotes a persistent low-intensity inflammatory state.
The anopheline mosquitoes that carry malaria were present 100 million years ago, new research shows, potentially shedding fresh light on the history of a disease that continues to kill more than 400,000 people annually.
Using HIV genetic data, researchers discovered that transgender women in Los Angeles are at higher risk of being in an HIV transmission network than men who have sex with men. In addition, cisgender men in these clusters should be considered at higher risk for HIV than previously thought.
Researchers of the University of Barcelona (UB) have analysed, with massive sequencing techniques for the first time, the evolution of the Hepatitis A virus with samples from patients. The results, published in the journal EBioMedicine, show the presence of variants of the virus that could escape the effects of the vaccine.
In recent decades, Europe has experienced a downward trend in the annual number of deaths. Not only was this trend not arrested by the economic recession that started in 2008, in fact, the rate of decline increased during the recession years. This acceleration has been evidenced by the results of a study published in Nature Communications.
By monitoring the spread of Zika virus through a densely populated Brazilian favela during a 2015 outbreak, researchers have gained new perspectives into the outbreaks of this virus in the Americas in recent years.
When the Zika virus arrived in the Americas in early 2015, it struck hard, infecting 73 percent of people in one Brazilian community at the epicenter of the pandemic, according to a new study led by the Yale School of Public Health. The study, conducted in collaboration with the Oswaldo Cruz Foundation-Brazilian Ministry of Health and international partners, is published in Science.
The higher a person's immunity to dengue virus, the lower their risk of Zika infection, an international team of scientists report today. The study -- which followed nearly 1,500 people living in a poor neighborhood at the heart of the 2015 Zika outbreak in Brazil -- also provides evidence for why Brazil's Zika epidemic has largely petered out.
