The drumbeats about the dangers of antibiotic resistance just got louder. The World Health Organization says antimicrobial resistance - which includes drug-resistant bacteria, viruses, fungi and parasites - is seen in every region of the world.
"The picture is consistent," says Dr. Keiji Fukuda, assistant director-general for health security at the WHO. "The capacity to treat serious infections is becoming less all over the world. ... This is something which is occurring in all countries of the world."
Antimicrobial drugs are one of the foundations of modern health care - something we all hope to rely on when we get sick with ailments including pneumonia, urinary tract or blood infections, diarrhea or sexually transmitted diseases, Fukuda says. These infections occur worldwide on a daily basis.
But because of overuse or misuse or improper use of existing treatments, the ability to fight these infections is getting harder and harder, he says. FULL POST

It's not a secret that some diabetics also have memory issues, but a new study suggests it's not just due to clogging of blood vessels - your brain may actually be shrinking.
When the brain shrinks, it's often because valuable brain cells that help us think and remember are dying. A loss of brain cells is a hallmark for Alzheimer's disease and other types of dementia.
In this new study, published in the journal Radiology, researchers looked at brain scans from a little more than 600 people age 55 and older with type 2 diabetes. They found that patients who lived with diabetes the longest had smaller brain volumes. FULL POST

Here's a roundup of five medical studies published this week that might give you insights into your health, mind and body. Remember, correlation is not causation, so if a study finds a connection between two things, it doesn't mean that one causes the other.
Low tolerance for pain? Blame your parents
Researchers believe they've identified four genes that are responsible for your ability to tolerate pain. In their study, they asked 2,721 people with chronic pain to rate their pain on a scale from 1 to 10, 10 being the most painful. Researchers then grouped the participants according to low-pain, moderate-pain or high-pain ratings, and identified which genes were more prevalent in each group.
“Chronic pain can affect every other part of life,” study author Dr. Tobore Onojjighofia said in a statement. “Finding genes that maybe play a role in pain perception could provide a target for developing new therapies and help physicians better understand their patients’ perceptions of pain.”

Young people who use marijuana may be at risk for heart attacks and other serious cardiovascular problems, a new study suggests.
Researchers reviewed records from the French Addictovigilance Network, a national system of centers in France that gather information about drug abuse and dependence. From 2006 to 2010, they found 35 reports of patients who had experienced cardiovascular complications following cannabis use. The study was published Tuesday in the Journal of the American Heart Association.

Every year, there are up to 870,000 prescriptions of codeine written for children in emergency rooms in the United States.
And that's a huge danger, because the narcotic can have particularly powerful effects on children. So powerful that the American Academy of Pediatrics issued guidelines against its use in 1997. Yet, despite those guidelines, a new study in the journal Pediatrics has found that little has changed in codeine prescribing habits.
Study author Dr. Sunitha Kaiser and her colleagues evaluated the National Hospital and Ambulatory Medical Care Survey database for emergency room visits of children between the ages of 3 and 17 from 2010 through 2010. They found found that in the nine years evaluated, the percentage of codeine prescriptions dropped very little - from 3.7% to 2.9%. FULL POST

Antidepressants may increase autism risk
Taking antidepressants during pregnancy may increase your child's risk of autism, especially if the baby is a boy, a new study suggests. Researchers looked at data from 966 mothers and their children. Kids who were exposed to SSRIs, also known as antidepressants, in utero were more likely to have autism or another developmental delay.
The researchers also distinguished between the sexes; boys with an autism spectrum disorder were three times as likely to have been exposed to SSRIs than typically developing children. But the risk of autism remains low, study authors say, and letting depression go untreated could have other serious consequences.

Scientists studying rare diseases should turn to social media
You may have seen the viral video of 4-year-old Eliza O'Neill laughing and playing as her parents talk about her life with Sanfilippo syndrome.
Scientists studying rare diseases often struggle to find patients and funding because so few people are affected. But social media is helping lighten the load. Viral videos and other campaigns often bring people with the same disease together, making it easier for scientists to identify clinical trial patients. In this study, researchers found social media outlets referred 84% of all patients for two pediatric rare disease trials.

You just think hard candy has fewer calories
The texture of our food affects our perception about its calorie content, says Dipayan Biswas, a marketing professor at the University of South Florida.
In a series of studies, researchers asked people to sample foods that were hard, soft, rough or smooth and then asked them how many calories they thought they had eaten. On average, study participants thought foods that were harder or rougher contained fewer calories.
"Understanding how the texture of food can influence calorie perceptions, food choice, and consumption amount can help nudge consumers towards making healthier choices," the study authors concluded.

Always get a second opinion
A new study finds more than 5%, or about 12 million U.S. adults, are misdiagnosed during an outpatient visit every year. The researchers estimate about half of those errors are harmful to the patient.
“The pressure to move patients in and out and the resulting brief clinical interactions between doctor and patients is a situation that fosters medical errors,” Dr. Otis Brawley of the American Cancer Society told Modern Healthcare.

You might want to think twice before heading out to your favorite oyster bar.
According to the Centers for Disease Control and Prevention's annual report card on foodborne illnesses, vibrio infections - most frequently found in raw or undercooked shellfish - have increased by 75% since the CDC's previous analysis period, 2006-2008.
That's about 6,600 cases for every 100,000 people - and for every case that is reported, the CDC estimates there 142 more that aren't diagnosed.
The microbe that causes vibrio is found naturally in coastal saltwater. It only represents 1% of foodborne illness in the United States, according to the CDC, but that's still 35,000 cases of food poisoning each year. Vibrio infections are at their highest rate since the CDC started tracking nine foodborne illness-related microorganisms in 1996, according to the new report. FULL POST

Being apathetic is usually defined as showing a lack of enthusiasm or energy. Most people who experience it say they just aren’t motivated to do anything.
Although anyone in any age group can become apathetic, it has been well documented that apathy tends to affect those in their golden years. Now scientists believe that an elderly person’s lack of emotion and indifference to the world could be a sign his or her brain is shrinking.
A study published Wednesday in the journal Neurology, and funded by the National Institutes of Health's National Institute of Aging, found that older folks, who are apathetic - but not depressed - may be suffering from smaller brain volumes than those without apathy. FULL POST

In what may be another step forward in treating spinal cord injuries, a safety trial will begin this year on the practice of injecting stem cells directly into the injury site, Neuralstem Inc. announced Wednesday.
The Maryland company said the University of California, San Diego's Institutional Review Board had approved its clinical trial protocol, which also has approval from the Food and Drug Administration.
The first eight patients who will be enrolled will be paraplegics who had a thoracic spinal cord injury one to two years ago and have no motor or sensory function below the point of their spinal cord injury.
Thoracic spinal cord injuries are rare, according to the Christopher and Dana Reeve Foundation, because of the protection afforded by a person's rib cage. In addition to the loss of function in legs, patients also experience a loss of physical sensation, bowel and bladder problems and sexual dysfunction. However, in most cases, function of the arms and hands are not affected.
It's the latest trial designed to inject stem cells into patients' spines. The trial is supposed to show that the drug - stem cells, in this case - is safe, although researchers hope to provide some benefit as well. FULL POST

It can be one of the most difficult diagnoses for a doctor to make: whether a brain-damaged patient is in a permanent vegetative state and will never wake up, or if he is in a minimally conscious state and may one day recover.
In fact, for patients with significant swelling in the brain, a doctor's outcome prediction is currently "a little better than flipping a coin," researchers Jamie Sleigh and Catherine Warnaby write in The Lancet this week.
