Even Easy Brain Concussion Can Lead To Serious Consequences.
Soldiers who experience submissive brain injuries from blasts have long-term changes in their brains, a meagre new study suggests. Diagnosing mild brain injuries caused by explosions can be challenging using prevailing CT or MRI scans, the researchers said. For their study, they turned to a unique type of MRI called diffusion tensor imaging. The technology was used to assess the brains of 10 American veterans of the wars in Iraq and Afghanistan who had been diagnosed with modest traumatizing brain injuries and a comparison group of 10 people without brain injuries.
The average occasion since the veterans had suffered their brain injuries was a little more than four years. The researchers found that the veterans and the resemblance group had significant differences in the brain's white matter, which consists mostly of signal-carrying nerve fibers. These differences were linked with publicity problems, delayed memory and poorer psychomotor examination scores among the veterans. "Psychomotor" refers to movement and muscle ability associated with intellectual processes.

Scientists Are Exploring The Human Cerebral Cortex
Scientists Are Exploring The Human Cerebral Cortex.
Higher levels of self-professed religious reliance appear to be reflected in increased thickness of a key brain area, a unfamiliar study finds. Researchers at Columbia University in New York City found that the outer layer of the brain, known as the cortex, is thicker in some areas all people who place a lot of significance on religion. The bone up involved 103 adults between the ages of 18 and 54 who were the children and grandchildren of both depressed survey participants and those who were not depressed.
A team led by Lisa Miller analyzed how often the participants went to church and the wreck of importance they placed on religion. This assessment was made twice over the track of five years. Using MRI technology, the cortical thickness of the participants' brains was also exact once.

Undetectable HIV Virus
Undetectable HIV Virus.
Fortunata Kasege was just 22 years past it and several months preggers when she and her husband came to the United States from Tanzania in 1997. She was hoping to earn a college step in journalism before returning home. Because she'd been in the process of moving from Africa to the United States, Kasege had not yet had a prenatal checkup, so she went to a clinic soon after she arrived. "I was very overwrought to be in the US, but after that crave flight, I wanted to know that everything was OK.
I went to the clinic with mixed emotions - lively about the baby, but worried, too," but she left the appointment feeling better about the baby and without worries. That was the continue time she'd have such a carefree feeling during her pregnancy. Soon after her appointment, the clinic asked her to come back in: Her blood evaluate had come back positive for HIV. "I was devastated because of the baby. I don't call to mind hearing anything they said about saving the baby right away.
It was a lot to interpret in. I was crying and scared that I was going to die. I was feeling all kinds of emotions, and I cogitation my baby would die, too. I was screaming a lot, and for ever someone told me, 'We promise we have medicine you can take and it can save the baby and you, too. Kasege started therapy right away with zidovudine, which is more commonly called AZT. It's a medicament that reduces the amount of virus in the body, known as the viral load, and that helps bust the chances of the baby getting the mother's infection.

Scientists Continue To Explore The Possibilities Of The Human Brain.
Electrical stimulation of a determined neighbourhood of the brain may help boost a person's facility to get through tough times, according to a tiny new study. Researchers implanted electrodes in the brains of two tribe with epilepsy to learn about the source of their seizures. The electrodes were situated in the part of the genius known as the "anterior midcingulate cortex". This region is believed to be involved in emotions, drag and decision-making.
When an electrical charge was delivered within this region, both patients said they experienced the expectation of an momentary challenge. Not only that, they also felt a determination to conquer the challenge. At the same time, their sympathy rate increased and they experienced physical sensations in the chest and neck.

Scientists Have Found New Causes Of Stroke
Scientists Have Found New Causes Of Stroke.
Could ache upward the risk for stroke? A new long-term study suggests just that - the greater the anxiety, the greater the jeopardy for stroke. Study participants who suffered the most anxiety had a 33 percent higher endanger for stroke compared to those with the lowest anxiety levels, the researchers found. This is intention to be one of the first studies to show an association between anxiety and stroke. But not everyone is convinced the coherence is real. "I am a little skeptical about the results," said Dr Aviva Lubin, affiliate stroke director at Lenox Hill Hospital in New York City, who had no part in the study.
The researchers muricate out that anxiety can be related to smoking and increased pulse and blood pressure, which are known jeopardize factors for stroke. However, Lubin still has her doubts. "It still seems a little hard-headed to fully buy into the fact that anxiety itself is a major risk factor that we need to deal with. Lubin said that treating peril factors like smoking, high blood pressure and diabetes are the keys to preventing stroke.
And "I waver that treating anxiety itself is going to decrease the gamble of stroke.The report was published Dec 19, 2013 in the online edition of the journal Stroke. The look at was led by Maya Lambiase, a cardiovascular behavioral medicine researcher in the area of psychiatry at the University of Pittsburgh School of Medicine. Her team collected data on more than 6000 common man aged 25 to 74 when they enrolled in the first US National Health and Nutrition Examination Survey, started in the inappropriate 1970s.

New Rules For The Control Of Food Safety
New Rules For The Control Of Food Safety.
A redesigned superintend to protect the nation's food supply from terrorism has been introduced by the US Food and Drug Administration, the intervention announced Friday in Dec 2013. The proposed guide would require the largest food businesses in the United States and in other nations to take steps to shelter facilities from attempts to contaminate the food supply. The FDA said it does not know of any cases where the edibles supply was intentionally tainted with the aim of inflicting widespread harm, and added that such events are distasteful to occur.

The Link Between Antidepressants And Autism
The Link Between Antidepressants And Autism.
Despite some concerns to the contrary, children whose moms old antidepressants during pregnancy do not appear to be at increased jeopardy of autism, a large novel Danish study suggests. The results, published Dec 19, 2013 in the New England Journal of Medicine, presentation some reassurance. There have been some hints that antidepressants called picky serotonin reuptake inhibitors (SSRIs) could be linked to autism. SSRIs are the "first-line" drug against depression, and allow for medications such as fluoxetine (Prozac), sertraline (Zoloft), citalopram (Celexa) and paroxetine (Paxil).
In one late-model US study, mothers' SSRI use during pregnancy was tied to a twofold increase in the edge that her child would have autism. A Swedish study saw a similar pattern, though the risk linked to the drugs was smaller. But both studies included only pint-sized numbers of children who had autism and were exposed to antidepressants in the womb. The recent study is "the largest to date" to look at the issue, using records for more than 600000 children born in Denmark, said tether researcher Anders Hviid, of the Statens Serum Institute in Copenhagen.
And overall, his crew found, there was no clear link between SSRI use during pregnancy and children's autism risk. Hviid cautioned that the pronouncement is still based on a small company of children who had autism and prenatal exposure to an SSRI - 52, to be exact. The researchers celebrated that it's not possible to rule out a small increase in autism risk. "At this point, I do not contemplate this potential association should feature prominently when evaluating the risks and benefits of SSRI use in pregnancy".
Commenting on the findings, Christina Chambers, foreman of the Center for the Promotion of Maternal Health and Infant Development at the University of California, San Diego, stated, "I deliberate this study is reassuring". One "important" specifics is that the researchers factored in mothers' mental health diagnoses - which ranged from the blues to eating disorders to schizophrenia. "How much of the risk is related to the medication, and how much is interconnected to the underlying condition? It's hard to tease out".

Dangerous Bacteria Live On Chicken Breasts
Dangerous Bacteria Live On Chicken Breasts.
Potentially unhealthy bacteria was found on 97 percent of chicken breasts bought at stores across the United States and tested, according to a experimental work in Dec 2013. And about half of the chicken samples had at least one breed of bacteria that was resistant to three or more classes of antibiotics, the investigators found. The tests on the 316 damp chicken breasts also found that most had bacteria - such as enterococcus and E coli - linked to fecal contamination.
About 17 percent of the E coli were a kidney that can cause urinary tract infections, according to the study, published online and in the February 2014 affair of Consumer Reports. In addition, slight more than 11 percent had two or more types of multidrug-resistant bacteria. Bacteria on the chicken were more rebellious to antibiotics used to promote chicken growth and to prevent poultry diseases than to other types of antibiotics, the retreat found.
These findings show that "consumers who buy chicken breast at their local grocery stores are very indubitably to get a sample that is contaminated and likely to get a bug that is multi-drug resistant. When people get heartsick from resistant bacteria, treatment may be getting harder to find," said Dr Urvashi Rangan, a toxicologist and directorate director of the Food Safety and Sustainability Center at Consumer Reports. The journal has been testing US chicken since 1998, and rates of contamination with salmonella have not changed much during that time, ranging from 11 percent to 16 percent of samples.

Diabetes Degrades Vision
Diabetes Degrades Vision.
Less than half of adults who are losing their materialization to diabetes have been told by a medical practitioner that diabetes could damage their eyesight, a new study found. Vision trouncing is a common complication of diabetes, and is caused by damage that the chronic disease does to the blood vessels within the eye. The imbroglio can be successfully treated in nearly all cases, but Johns Hopkins researchers found that many diabetics aren't taking heed of their eyes, and aren't even aware that vision loss is a potential problem. Nearly three of every five diabetics in hazard of losing their sight told the Hopkins researchers they couldn't remember a doctor describing to them the link between diabetes and vision loss.
The study appeared in the Dec 19, 2013 online promulgation of the journal JAMA Ophthalmology. About half of people with diabetes said they hadn't seen a health-care provider in the earlier year. And two in five hadn't received a shapely eye exam with dilated pupils, the study authors noted. "Many of them were not getting to someone to go over them for eye problems," said study leader Dr Neil Bressler, a professor of ophthalmology at the Johns Hopkins University School of Medicine.
And "That's a denigration because in many of these cases you can regale this condition if you catch it in an early enough stage," added Bressler, who is also chief of the retina unit at the Johns Hopkins Wilmer Eye Institute. One-third of the people said they already had suffered some envisioning loss related to their diabetes, according to the report. Bressler said vision damage can be prevented or halted in 90 percent to 95 percent of cases, but only if doctors get to patients with dispatch enough.
Drugs injected into the sight can reduce swelling and lower the risk of vision loss to less than 5 percent. Laser cure has also been used to treat the condition, the researchers said. Dr Robert Ratner, key scientific and medical officer for the American Diabetes Association, called the findings "frightening" and "depressing. This tabloid is an excellent example of where the American health care delivery system has fallen down in an square where we can clearly do better".
For the study, researchers used survey data collected by the US Centers for Disease Control and Prevention between 2005 and 2008 to review article the responses of people with archetype 2 diabetes who had "diabetic macular edema". This condition occurs when high blood sugar levels associated with unsatisfactorily controlled diabetes cause damage to the small blood vessels in the retina, the light-sensitive mass lining the back wall of the eye. As the vessels leak or shrink, they can cause node in the macula - a spot near the retina's center that is responsible for your central vision.

Smoking In The US Decreases
Smoking In The US Decreases.
Total smoking bans in homes and cities greatly flourish the good chance that smokers will cut back or quit, according to a new study Dec 27, 2013. "When there's a out-and-out smoking ban in the home, we found that smokers are more qualified to reduce tobacco consumption and attempt to quit than when they're allowed to smoke in some parts of the house," Dr Wael Al-Delaimy, leader of the division of global health, department of family and precautionary medicine, University of California, San Diego, said in a university news release. "The same held unvarnished when smokers report a total smoking ban in their city or town.

How To Carry Luggage Safely
How To Carry Luggage Safely.
Carrying and lifting oppressive baggage during the holidays can lead to neck, wrist, back and shoulder pain and injuries unless you take out-and-out safety precautions, an orthopedic surgeon says. In 2012, nearly 54000 luggage-related injuries occurred in the United States, according to the US Consumer Product Safety Commission Dec 2013. "Holiday socialize can be uniquely stressful and physically taxing, especially when transporting weighty and cumbersome luggage," said Dr Warner Pinchback, a spokesman for the American Academy of Orthopaedic Surgeons.
And "To make sure that you appear at your holiday destination free from pain, it's important to know how to optimally choose, pack, bear and lift your luggage," he added in an academy news release. The academy offers the following things safety tips. When buying new luggage, prefer a sturdy, lightweight piece with wheels and a handle. Don't overpack.
Try to carry items in a few smaller bags as an alternative of one large suitcase. Keep in mind that many airlines restrict the size and incline of carry-on luggage. Bend your knees when lifting. The safe way to hoist a burdensome item such as luggage is to stand alongside of it, bend at the knees - not the waist - and use your stump muscles as you grab the handle and straighten up. Be sure to hold the bag precise to your body when lifting.
