Postsurgical pain scores were highly correlated with reports of overall patient satisfaction during hospital stays, in a new finding that was true for some types of surgery more than others. The researchers stressed the importance of improving patient care in the peri-operative setting in alignment with new federal requirements tying performance to pay.
Preschoolers can be smarter than college students at figuring out how unusual toys and gadgets work because they're more flexible and less biased than adults in their ideas about cause and effect, according to new research.
Cerebral malaria is a serious complication of infection with the malaria parasite, affecting approximately one in a thousand children in areas where malaria is common. Many of the patients die, and among those who survive, about a third have lasting cognitive and neurological disabilities, including epilepsy and learning disorders. A new study shows that a known drug can prevent brain damage in a cerebral malaria mouse model and eliminate subsequent neurological deficits.
You may have only had one glass of wine with dinner, but if you’re 55 or older, that single serving may hit you hard enough to make you a dangerous driver. Researchers tested how drinking legally non-intoxicating levels of alcohol affect the driving skills of two age groups: 36 people ages 25 to 35 and 36 people ages 55 to 70. They found that although neither age group imbibed enough alcohol to put them over the legal driving limit, a blood alcohol level of 0.08, just one drink can affect the driving abilities of older drivers.
Soldiers returning home from war may find themselves engaged in an even tougher conflict. A new paper examines the 'warring identities' many veterans confront when transitioning from soldier to civilian life. "You can't really do research on veterans mental health without some kind of dialogue on PTSD, but we're trying to move away from the standard PTSD framework to contextualize the veteran experience and get a more accurate picture of what vets returning from war look like as opposed to just looking at the medical side of things," the author said.
Cannabinoid receptors, through which marijuana exerts its effects, have been found in a key emotional hub in the brain involved in regulating anxiety and the flight-or-fight response. This is the first time cannabinoid receptors have been identified in the central nucleus of the amygdala in a mouse model.
Detailed picture created of membrane protein linked to learning, memory, anxiety, pain and brain disorders
The most detailed 3-D picture yet has been created of a membrane protein linked to learning, memory, anxiety, pain and brain disorders such as schizophrenia, Parkinson’s, Alzheimer’s and autism. The mGlu1 receptor, which helps regulate the neurotransmitter glutamate, belongs to a superfamily of molecules known as G protein-coupled receptors (GPCRs). GPCRs sit in the cell membrane and sense various molecules outside the cell, including odors, hormones, neurotransmitters and light. After binding these molecules, GPCRs trigger a specific response inside the cell. More than one-third of therapeutic drugs target GPCRs -— including allergy and heart medications, drugs that target the central nervous system and anti-depressants.
Approximately one in six veterans struggles with substance abuse, and 20 percent show signs of mental health issues or cognitive impairments, previous research has shown. These risk factors, combined with a lack of resources, could be contributing to an increase of veterans entering the criminal justice system, according to a report. Researchers have investigated ways that social workers can address veterans' needs and keep them out of jail.
People born unable to see are readily capable of learning to perceive the shape of the human body through soundscapes that translate images into sound, according to researchers. With a little training, soundscapes representing the outlines and silhouettes of bodies cause the brain's visual cortex -- and specifically an area dedicated in normally sighted people to processing body shapes -- to light up with activity.
It is often said that music is a universal language. However, a new report finds that music doesn't speak to everyone. There are people who are perfectly able to experience pleasure in other ways who simply don't get music in the way the rest of us do.
Reelin, a crucial protein for adult brain plasticity, recovers cognitive functions in mice with Alzheimer’s disease. This is one of the main results a new study. Alzheimer's disease is a neurodegenerative disease characterized by progressive cognitive deficits, synaptic loss and neuronal death. This new preclinical study demonstrates that an increase in Reelin brain levels avoids cognitive deterioration in mouse models of Alzheimer's disease. Moreover, Reelin delays amyloid-beta fibril formation in vitro and reduces amyloid deposits in mice with Alzheimer's.
Millions of high school and college algebra students are united in a shared agony over solving for x and y, and for those to whom the answers don't come easily, it gets worse: Most preschoolers and kindergarteners can do some algebra before even entering a math class. A new study finds that most preschoolers and kindergarteners, or children between 4 and 6, can do basic algebra naturally.
A study reveals new information about the motor circuits of the brain that may one day help those developing therapies to treat conditions such as stroke, schizophrenia, spinal cord injury or Alzheimer's disease. In this study, which processed images and reconstructed neuronal motor circuitry in the brain, the researchers collected and analyzed data on minute structures over various developmental stages, linking neuroscience and computer science.
E-cigarettes, promoted as a way to quit regular cigarettes, may actually be a new route to conventional smoking and nicotine addiction for teenagers, according to a new study. In the first analysis of the relationship between e-cigarette use and smoking among adolescents in the United States, researchers found that adolescents who used the devices were more likely to smoke cigarettes and less likely to quit smoking. The study of nearly 40,000 youth around the country also found that e-cigarette use among middle and high school students doubled between 2011 and 2012, from 3.1 percent to 6.5 percent.
A new study shows that more than half the survivors in one Japanese town exhibited 'clinically concerning' symptoms of PTSD following the country's mega-earthquake and tsunami. Two-thirds of survivors also reported symptoms of depression. Having work to do has proven important in increasing resilience.
Classroom programs designed to improve elementary school students' social and emotional skills can also increase reading and math achievement, even if academic improvement is not a direct goal of the skills building, according to a study. The benefit holds true for students across a range of socio-economic backgrounds.
The uplifting effects of energy drinks are well advertised, but a new report finds consumption among teenagers may be linked with poor mental health and substance use. The researchers found that high school students prone to depression as well as those who are smoke marijuana or drink alcohol are more likely to consume energy drinks than their peers. The researchers are calling for limits on teen's access to the drinks and reduction in the amount of the caffeine in each can.
For Chinese and Vietnamese immigrant parents and their children, success is equal to getting straight As, graduating from an elite university and pursuing an advanced degree. However, these narrow measures of success can make those who do not fulfil the strict aspirations feel like ethnic outliers, new research demonstrates. Decoupling race and ethnicity from achievement could give young Asian Americans more freedom in choosing careers.
Scientists have created a robotic drumming prosthesis with motors that power two drumsticks. The first stick is controlled both physically by the musicians’ arms and electronically using electromyography (EMG) muscle sensors. The other stick “listens” to the music being played and improvises.
For many people with advanced cardiac insufficiency, a heart transplant may be their only hope. But waiting for a donor heart to come along is a race against time. Patients who remain active and stay in good shape psychologically can significantly increase their chances of surviving this period. Anxiety-ridden, depressive and passive patients, on the other hand, run the risk of further serious deterioration of their heart's ability to function, a research study shows.
