For women of average weight in Western countries, five years of menopausal hormone therapy (MHT), starting at age 50 years, would increase breast cancer incidence from age 50 to 69 years by about one additional case in every 50 users of oestrogen plus daily progestogen MHT, one in every 70 users of oestrogen plus intermittent progestogen MHT, and one in every 200 users of oestrogen-only MHT.

A new method for permanently marking cells infected with chikungunya virus could reveal how the virus continues to cause joint pain for months to years after the initial infection, according to a study published August 29 in the open-access journal PLOS Pathogens by Deborah Lenschow of Washington University School of Medicine in St. Louis, and colleagues. According to the authors, uncovering the mechanisms for long-term disease could aid in the development of treatments and preventative measures for this incapacitating, virally induced chronic arthritis.

BOSTON- Opioid-related deaths continue to take the lives of thousands in the U.S. each year, with non-fatal opioid overdoses as a significant risk factor for a subsequent fatal overdose. Post-overdose interventions are emerging in affected communities, using what support systems are available to assist in the program design.

Survivors often do not seek treatment or overdose risk reduction services immediately after an overdose for many reasons, including shame and stigma, and lack of referrals to substance use treatment.

By mapping out more than 100,000 immune cells in patients with Crohn's disease, Mount Sinai researchers have discovered a signature of cells that are involved in a type of the disease that does not respond to treatment, according to a study published in Cell in August. The discovery opens the door to identifying biomarkers and tailoring therapeutic options for patients.

The new type of drugs for type 2 diabetes, the so-called SGLT2 inhibitors, are associated with a reduced risk of heart failure and death as well as of major cardiovascular events, a major Scandinavian registry study led from Karolinska Institutet reports in The BMJ.

A KAIST research team reported the development of a DNA vaccine for Severe Fever with Thrombocytopenia Syndrome Virus (SFTSV) which completely protects against lethal infection in ferrets. The team confirmed that ferrets immunized with DNA vaccines encoding all SFTSV proteins showed 100% survival rate without detectable viremia and did not develop any clinical symptoms. This study was published in Nature Communications on August 23.

PHILADELPHIA - Blocking a kinase known as CDK7 sets off a chain reaction that results in the death of prostate cancer cells that have spread and are resistant to standard therapies, according to a new study from researchers in the Abramson Cancer Center at the University of Pennsylvania. The team identified the role of CDK7 as the on/off switch that controls Med-1, a process that works in partnership with the androgen receptor to drive prostate cancer growth. Researchers show turning the switch off eventually leads to the death of cancer cells in mice.

Researchers at the Stanford University School of Medicine have found that inflammation in the lungs of rats, triggered by something as simple as the flu, may wake up a silent genetic defect that causes sudden onset cases of pulmonary hypertension, a deadly form of high blood pressure in the lungs.

Researchers have come one step closer to understanding how our immune system responds to acute dengue fever, a disease that has affected hundreds of thousands of people in Southeast Asia this summer alone. In a study published today in Nature Communications, researchers at Karolinska Institutet and Duke-NUS Medical School show that so-called natural killer cells were especially active shortly after an infection. The discovery could hopefully contribute to the development of new vaccines and improve care of patients with acute infections.

MINNEAPOLIS - Can a person with multiple sclerosis (MS) get regular vaccines? According to a new guideline, the answer is yes. The guideline, developed by the American Academy of Neurology (AAN), recommends that people with MS receive recommended vaccinations, including yearly flu shots. The guideline is published in the August 28, 2019, online issue of Neurology®, the medical journal of the AAN, and is endorsed by the Consortium of Multiple Sclerosis Centers and by the Multiple Sclerosis Association of America.

In research published today in The Lancet and funded by National Institute for Health Research (NIHR), researchers from King's College London have found that early, planned delivery for women with pre-term pre-eclampsia reduces complications and severe hypertension, as well as costs, compared to the current method of care.

An individual's trust in institutions such as the CDC, and how close they live to a recent measles outbreak, may affect their attitudes on measles vaccination, according to a study published August 28, 2019 in the open-access journal PLOS ONE by Florian Justwan of the University of Idaho, USA, and colleagues.

Washington, DC - August 28, 2019 - The pathogen Clostridium difficile, which causes one of the most common hospital-acquired infections in the United States, may have accomplices that until now have gone largely unnoticed.

A new platform that combines two established imaging methods can peer into both the structure and molecular makeup of the prostate in men with prostate cancer. The technology is more sensitive and comprehensive compared to current "gold standard" methods, indicating it could allow clinicians to diagnose and monitor prostate cancers in real time with greater accuracy and confidence. Prostate cancer affects over 1.2 million people worldwide and is one of the most common malignancies in men.

Plant diseases, especially those caused by fungal pathogens, jeopardize global crop biosecurity and preventing them requires rapid detection and identification of causal agents. Traditional methods for crop disease diagnosis rely on the expertise of pathologists who can identify diseases by eye, but this approach comes with many limitations, including the reliance on physical appearance of disease symptoms.
