New technology improves atrial fibrillation detection after stroke

Posted: 12 Jul 2019 02:41 PM PDT

It's important to determine whether stroke patients also experience atrial fibrillation (Afib). Monitoring technology could make the process easier and more accurate.

Improving care quality for hospitalized socially at-risk patients

Posted: 12 Jul 2019 12:19 PM PDT

Nurses play a pivotal role in caring for hospitalized patients with social risk factors and preparing them for discharge. Now, a new study illustrates how certain health system constraints present barriers to effective care and impact outcomes for patients with high social risks.

Novel nanoparticles deliver CRISPR gene editing tools into the cell with much higher efficiency

Posted: 12 Jul 2019 12:19 PM PDT

Researchers have developed a significantly improved delivery mechanism for the CRISPR/Cas9 gene editing method in the liver. The delivery uses biodegradable synthetic lipid nanoparticles that carry the molecular editing tools into the cell to precisely alter the cells' genetic code with as much as 90 percent efficiency. The nanoparticles could help overcome technical hurdles to enable gene editing in a broad range of clinical therapeutic applications.

How artificial intelligence can be used to more quickly and accurately diagnose breast cancer

Posted: 12 Jul 2019 12:19 PM PDT

Breast ultrasound elastography is an emerging imaging technique used by doctors to help diagnose breast cancer by evaluating a lesion's stiffness in a non-invasive way. Researchers identified the critical role machine learning can play in making this technique more efficient and accurate in diagnosis.

How good is your hospital?

Posted: 12 Jul 2019 10:33 AM PDT

Researchers have proposed a rating system that standardizes and combines data from five leading hospital rating systems into an easy-to-understand composite score of one to 10 that will help guide consumer's hospitals choice.

Hear them roar: How humans and chickadees understand each other

Posted: 12 Jul 2019 10:33 AM PDT

Is there something universal about the sounds we make that allows vocal learners -- like songbirds -- to figure out how we're feeling? Sounds like it, according to new research.

C. difficile resists hospital disinfectant, persists on hospital gowns, stainless steel

Posted: 12 Jul 2019 10:33 AM PDT

Surgical gowns and stainless steel remained contaminated with the pathogen Clostridium difficile even after being treated with the recommended disinfectant, according to new research.

New gene linked to healthy aging in worms

Posted: 12 Jul 2019 09:02 AM PDT

Damage to gene causes impaired movement in adult worms.

Dentistry: Root canal work not so bad after all

Posted: 12 Jul 2019 09:02 AM PDT

Root canal work is not as bad as people think when compared to other dental procedures. Self-reporting of their dental health suggests that patients find the procedure no worse than other dental work which overturns the popular belief that root canal work is the most unpleasant dental treatment.

Preterm babies are less likely to form romantic relationships in adulthood

Posted: 12 Jul 2019 09:02 AM PDT

Adults who were born preterm (under 37 weeks gestation) are less likely to have a romantic relationship, a sexual partner and experience parenthood than those born full term. The meta-analysis with data from up to 4.4 million adult participants showed that those born preterm are 28% less likely to ever be in a romantic relationship.

HIV: Reprogramming cells to control infection

Posted: 12 Jul 2019 09:02 AM PDT

Following research on cohorts, scientists have described the characteristics of CD8 immune cells in these 'HIV controller' subjects. The unique antiviral power of these immune cells can be attributed to an optimal metabolic program that confers persistence and the ability to react effectively against infected cells. Working ex vivo, the scientists successfully reprogrammed cells from infected non-controller individuals to give them the same antiviral potency as controllers' cells.

Fewer than half of US adults exposed to court-ordered anti-smoking advertisements

Posted: 12 Jul 2019 09:02 AM PDT

The tobacco industry's court-ordered anti-smoking advertisements reached just 40.6 percent of US adults and 50.5 percent of current smokers in 2018, according to new research. Exposure to the advertisements was even lower among certain ethnic and socioeconomic subgroups historically targeted by tobacco industry marketing.

Seeing greenery linked to less intense and frequent unhealthy cravings

Posted: 12 Jul 2019 09:02 AM PDT

New research shows that being able to see green spaces from your home is associated with reduced cravings for alcohol, cigarettes and harmful foods.

Targeting a key protein may keep ovarian cancer cells from spreading

Posted: 12 Jul 2019 07:57 AM PDT

Preventing a protein from doing its job may keep a certain type of ovarian cancer cell from growing and dividing uncontrollably in the lab, according to a new study.

Air pollution, coronary atherosclerosis

Posted: 12 Jul 2019 07:57 AM PDT

Researchers found that long-term exposure to particulate matter and nitrogen dioxide, as well as proximity to vehicular traffic, were associated with severity of coronary artery calcium, or the buildup of plaque in the artery walls. The study was conducted on 8,867 Chinese adults aged 25 to 92.

Rise in early onset colorectal cancer not aligned with screening trends

Posted: 12 Jul 2019 07:57 AM PDT

A new study finds that trends in colonoscopy rates did not fully align with the increase in colorectal cancer (CRC) in younger adults, adding to evidence that the rise in early onset CRC is not solely a result of more detection.

Marathon-running molecule could speed up the race for new neurological treatments

Posted: 12 Jul 2019 07:57 AM PDT

Scientists have discovered a new process that sets the fastest molecular motor on its marathon-like runs through our neurons.

The brain's pathways to imagination may hold the key to altruistic behavior

Posted: 12 Jul 2019 07:57 AM PDT

Researchers used neuroimaging to identify multiple neural pathways in the brain that explain the relationship between imagination and the willingness to help others.

Even in svelte adults, cutting about 300 calories daily protects the heart

Posted: 11 Jul 2019 03:37 PM PDT

In adults already at a healthy weight or carrying just a few extra pounds, cutting around 300 calories a day significantly improved already good levels of cholesterol, blood pressure, blood sugar and other markers.

AI beats professionals in six-player poker

Posted: 11 Jul 2019 11:13 AM PDT

An artificial intelligence program has defeated leading professionals in six-player no-limit Texas hold'em poker, the world's most popular form of poker.
