ACP expresses 'strongest opposition' to Better Care Reconciliation Act of 2017

EurekAlert! - Mié, 06/21/2017 - 22:00
The American College of Physicians (ACP) expresses our strongest possible opposition to the Better Care Reconciliation Act (BCRA) of 2017, legislation to repeal and replace the Affordable Care Act (ACA).

Turtle go-slow zone extensions needed

Researchers design sounds that can be recorded by microphones but inaudible to humans

EurekAlert! - Mié, 06/21/2017 - 22:00
Researchers at the University of Illinois have designed a sound that is completely inaudible to humans (40 kHz or above) yet is audible to any microphone. The sound combines multiple tones that, when interacting with the microphone's mechanics, create what researchers call a 'shadow,' which is a sound that the microphones can detect.

Changes to diet, physical activity & behavior may reduce obesity in children, adolescents

EurekAlert! - Mié, 06/21/2017 - 22:00
Latest health evidence shows that making changes to diet, physical activity and behavior may reduce obesity in children and adolescents.

Combined molecular biology test is the first to distinguish benign pancreatic lesions

EurekAlert! - Mié, 06/21/2017 - 22:00
When performed in tandem, two molecular biology laboratory tests distinguish, with near certainty, pancreatic lesions that mimic early signs of cancer but are completely benign. The lesions almost never progress to cancer, so patients may be spared unnecessary pancreatic cancer screenings or operations. The two-test combination is the only one to date that can accurately and specifically identify these benign pancreatic lesions.

Child safety or parental duty: New study maps out core concepts in the vaccination debate

EurekAlert! - Mié, 06/21/2017 - 22:00
'A single phrase can conjure up completely different images in our minds, depending on how that concept is organized in our mental models,' said Samarth Swarup, a research assistant professor at Virginia Tech.

Lessons from whale population collapse could help future species at risk

EurekAlert! - Mié, 06/21/2017 - 22:00
A study of historic whaling records has revealed there were warning signs that populations of commercially harvested whales were heading for global collapse up to 40 years before the event.The research by scientists from IMAS and Switzerland's University of Zurich has the potential for application to other species to pinpoint early warning signs that a population is at risk of collapse due to pressures such as overfishing or climate change.

Scientists recreate Californian Indian water bottles to study ancient exposure to chemicals

EurekAlert! - Mié, 06/21/2017 - 22:00
Water bottles replicated in the traditional method used by Native Californian Indians reveal that the manufacturing process may have been detrimental to the health of these people. The study is published this week in the open access journal Environmental Health.

New report examines evidence on interventions to prevent cognitive decline, dementia

EurekAlert! - Mié, 06/21/2017 - 22:00
Cognitive training, blood pressure management for people with hypertension, and increased physical activity all show modest but inconclusive evidence that they can help prevent cognitive decline and dementia, but there is insufficient evidence to support a public health campaign encouraging their adoption, says a new report from the National Academies of Sciences, Engineering, and Medicine.

Researchers show first evidence of using cortical targets to improve motor function

EurekAlert! - Mié, 06/21/2017 - 22:00
University of Miami Miller School of Medicine's Dr. Monica A. Perez, Associate Professor, Department of Neurological Surgery and The Miami Project, and colleagues, recently published 'A novel cortical target to enhance hand motor output in humans with spinal cord injury' in the June issue of Brain that provides the first evidence that cortical targets could represent a novel therapeutic site for improving motor function in humans paralyzed by spinal cord injury.

Patient-inspired research uncovers new link to rare disorder

EurekAlert! - Mié, 06/21/2017 - 22:00
Peroxisomal biogenesis disorder, which has been linked only to lipid metabolism, is also associated with sugar metabolism.

Tourette Syndrome risk increases in people with genetic copy variations

EurekAlert! - Mié, 06/21/2017 - 22:00
An international team that just conducted the largest study of Tourette Syndrome has identified genetic abnormalities that are the first definitive risk genes for the disorder.

Scientists uncover origins of the Sun's swirling spicules

EurekAlert! - Mié, 06/21/2017 - 22:00
For the first time, a computer simulation -- so detailed it took a full year to run -- shows how spicules form, helping scientists understand how spicules can break free of the sun's surface and surge upward so quickly.

Intensive blood pressure lowering benefits patients with chronic kidney disease

EurekAlert! - Mié, 06/21/2017 - 22:00
In individuals with chronic kidney disease, targeting a systolic blood pressure to <120 mm Hg resulted in lower risks of cardiovascular events and premature death, compared with standard targeting to <140 mm Hg. There was a slightly faster decline in kidney function in the intensive group, but no increase in rates of kidney failure or serious adverse events.

Crowdsourced data may inaccurately represent some population groups

EurekAlert! - Mié, 06/21/2017 - 22:00
While crowdsourcing, a practice that enables study participants to submit data electronically, has grown in use for health and medical research, a study led by UC San Francisco comparing the online approach to a standard telephone survey has found that certain crowdsourced groups are either over- or underrepresented by age, race/ethnicity, education and physical activity.

Study uncovers link between male hormones and metabolic disease in polycystic ovary syndrome

EurekAlert! - Mié, 06/21/2017 - 22:00
Scientists from the University of Birmingham have discovered the link between increased male hormones and metabolic complications such as diabetes and fatty liver disease in patients with polycystic ovary syndrome (PCOS).

Study debunks claim of greatly improved survival rate for gunshot victims

EurekAlert! - Mié, 06/21/2017 - 22:00
The survival rate of US gunshot victims has not shown a marked improvement, as other recent studies have suggested, according to new research from Duke University and the University of California, Davis. The purported increase in survival rate had been credited to improvements in emergency treatment and medical care of critically injured patients. But on close analysis, researchers found problems in the way data was collected and coded.

Seafood poisoning bug thwarts a key host defense by attacking the cell's cytoskeleton

EurekAlert! - Mié, 06/21/2017 - 22:00
The leading cause of acute gastroenteritis linked to eating raw seafood disarms a key host defense system in a novel way: It paralyzes a cell's skeleton, or cytoskeleton.

Snake fungal disease identified in wild British snakes for first time

EurekAlert! - Mié, 06/21/2017 - 22:00
Europe's wild snakes could face a growing threat from a fungal skin disease that has contributed to wild snake deaths in North America, according to an international collaborative study, led by conservation charity ZSL (Zoological Society of London) alongside partners including the US Geological Survey. The new study is published in the journal Scientific Reports.
