A better way to measure mortality trends?

Thu, 17/08/2017 - 8:20pm
A new study suggests long-term mortality trends may be better understood by focusing on life-years lost -- remaining life expectancy for a decedent -- instead of solely looking at cause of death.

Cigarette makers shifted stance on nicotine patches, gum, study shows

Thu, 17/08/2017 - 8:20pm
Tobacco companies have known for decades that, without counseling, NRT hardly ever works, and that consumers often use it to complement smoking. This insight from the formerly secret industry documents, outlines a new report.

Community health workers lead to better health, lower costs for Medicaid patients

Thu, 17/08/2017 - 8:20pm
As politicians struggle to solve the nation's healthcare problems, a new study finds a way to improve health and lower costs among Medicaid and uninsured patients. Researchers showed that patients who received support from community health workers (CHWs) had 30 percent fewer hospital admissions in one year compared to those who did not receive CHW support. The results also showed reductions in cigarette smoking, obesity, diabetes severity, and mental illness.

Gold nanostars and immunotherapy vaccinate mice against cancer

Thu, 17/08/2017 - 8:20pm
By combining an FDA-approved cancer immunotherapy with an emerging tumor-roasting nanotechnology, researchers improved the efficacy of both therapies in a proof-of-concept study using mice. The potent combination also attacked satellite tumors and distant cancerous cells, completely curing two mice and effectively vaccinating one against the disease.

Loans Applications? New techniques to measure social bias in software

Thu, 17/08/2017 - 8:20pm
Today, banks are increasingly using software to decide who will get a loan, courts to judge who should be denied bail, and hospitals to choose treatments for patients. These uses of software make it critical that the software does not discriminate against groups or individuals, say computer science researchers.

Tuberculosis drug may work better than others in its class

Thu, 17/08/2017 - 6:18pm
Treatment of tuberculosis involves a combination of several drugs, sometimes including drugs from a class known as fluoroquinolones. Using computer simulations, scientists have shown that the fluoroquinolone known as moxifloxacin may be superior to two other commonly used fluoroquinolones.

Brain regions most likely to cause epilepsy seizures

Thu, 17/08/2017 - 6:18pm
Scientists have developed a new way to detect which areas of the brain contribute most greatly to epilepsy seizures, according to a new study. The strategy could help surgeons select specific brain areas for removal to stop seizures.

Worm atlas profiles gene readouts in every cell type in the animal

Thu, 17/08/2017 - 6:18pm
A worm atlas has been built that profiles gene readouts for every kind of cell in the animal. This is the first time this type of comprehensive profiling for a multi-cellular organism has been created. The study was conducted at a larval stage of the roundworm C. elegans. The resource should have many uses, such as for studies on how genetic instructions guide the formation of body parts.

Non-toxic, lubricant-infused coatings deter mussels and prevent their attachment by disrupting their mechanosensory and adhesive systems

Thu, 17/08/2017 - 6:17pm
Mussels are one of the worst perpetrators of biofouling, or the unwanted accumulation of organisms on underwater structures. A team of scientists has demonstrated that a lubricant-infused surface effectively prevents mussels from sticking by masking the solid surface with a layer of liquid.

New Pathology Atlas maps genes in cancer to accelerate progress in personalized medicine

Thu, 17/08/2017 - 6:17pm
A new Pathology Atlas is launched today with an analysis of all human genes in all major cancers showing the consequence of their corresponding protein levels for overall patient survival. The difference in expression patterns of individual cancers observed in the study strongly reinforces the need for personalized cancer treatment based on precision medicine.
