Health Roundup - Food

WALNUTS make men more fertile:

Scientists claim the crunchy snack is essential for boosting sperm quality. In about 40% of cases, the male is the sole or contributing cause of infertility. Eating 2.5 ounces of walnuts a day could improve fertility in males, study claims.  Walnuts reduce lipid peroxidation - a process that damages sperm cells and they are the only tree nut made up of fats that are destroyed by the damage

Eating foods rich in omega-3 can reduce harm caused by air pollution by up to half.

Researchers at Harvard Medical School discovered that toxic particles can penetrate through the lungs into other organs, including the brain and testicles.  Poor air quality is a major cause of disease and death – increasing the risk of stroke, heart disease, lung cancer, and chronic and acute respiratory diseases, including asthma. But the study found omega-3 fatty acids in oily fish, soy beans and spinach can be used to prevent and treat the damage caused by polluted air.

Grab a MOCHA! Caffeine combined with cocoa can enhance your brain function

Researchers studied participants who drank coffee and hot chocolate for a year.  They found that while coffee boosts energy levels, hot chocolate relieves anxiety. Combining the two drinks is the best way to improve your attention span


Could fruit and steak cure epilepsy?
Study claims that a low-carb, high-fat diet is the key to controlling seizures as it alters the activity of brain cells.

Super-refractory status epilepticus (SRSE) is the most severe classification of the brain condition, killing 60 per cent of sufferers....  new research [from John Hopkins University] suggests that a ketogenic diet, high in fruit and steak,  could be used in future as a life-saving treatment for patients.  High in fats and low in carbohydrates, the diet alters the activity of brain cells to prevent deadly fits, scientists claim.

Study author Mackenzie Cervenka said: 'We can only state that it appears to work in some patients to halt status epilepticus and reduces the frequency of their seizures... What we can say is that the ketogenic diet is promising for at least a subset of patients... Any safe means we have of getting patients off of anesthesia and out of a coma quickly will be welcome."

9 Reasons You Should Eat Dark Chocolate Every Single Day

1. Dark chocolate just makes you happy.  It contains tryptophan, an amino acid that’s used by the brain to make serotonin, the neurotransmitter that makes us feel happiness.

2. Dark chocolate with a high cocoa content contains a solid amount of soluble fiber. A 100-gram bar of 70-85 percent chocolate has 11 grams of fiber. Soluble fiber helps keep cholesterol down, keeps you feeling fuller longer, and is good for your digestive health.

3. Eating dark chocolate might be good for your brain. That’s right, eating chocolate may keep your brain sharp and help you ward off dementia. A four-decade long study found that people with frequent chocolate consumption preformed better on brain-powered tests.

4. It’s good for your heart, too. Eating dark chocolate may lower your risk of cardiovascular disease. One study showed that eating chocolate five or more times a week lowered the risk of cardiovascular disease by 57 percent.

5. Dark chocolate makes for happier babies. And who doesn’t want a happy baby? A Finnish study found that mothers who ate more chocolate during pregnancy had happier, less fussy babies. This is great news for pregnant women everywhere.

6. It’s got the flavonoids we all want and need. Flavonoids are a plant-based antioxidant found in cocoa, and are one of the main reasons that dark chocolate is so good for you. These antioxidants may lower blood pressure and cholesterol, and also maintain the health of your blood vessels.

7. Dark chocolate is also good for your skin. Eating it can actually help protect you from sunburn thanks to two antioxidants, phenols and catechins, found in dark chocolate.

8. It’s a natural stress reliever ― Dark chocolate is found to lower the levels of stress hormones, which could very well be part of the reason you crave the stuff when feeling stressed out.

Round-up of new technologies in the field of medicine

Computers Turn Medical Sleuths and Identify Skin Cancer, Wall St Journal

When it comes to melanoma, early detection is a matter of life and death. But it takes a trained eye to distinguish a harmless blemish from cancer, and many people around the world lack ready access to a dermatologist...Researchers at Stanford University have found a way to get a computer, using its algorithm, to identify skin cancer as reliably as board-certified dermatologists can. The hope is that, eventually, scientists can get this to happen on a smartphone anywhere in the world.

Google's artificial intelligence can diagnose cancer faster than human doctors

The system is able to scan samples to determine whether or not tissues are cancerous...it's unlikely to replace human pathologists just yet. The software only looks for one thing - cancerous tissue - and is not able to pick up any irregularities that a human doctor could spot.

Israeli technology revolutionizes heart attack detection with one drop of blood

Israeli technology has changed the face of heart attack detection with a kit so small it fits in the palm of your hand...

A health professional needs only one drop of blood to let a patient know if a heart attack has occurred. If two stripes appear on the kit, the result is positive and the patient must immediately receive additional care. The test is easy, noninvasive and takes less than 15 minutes to perform.

Many people believe they can identify classic heart attack symptoms, which include chest pain, dizziness, nausea, pain traveling particularly to the left arm, wheezing and extreme anxiety similar to a panic attack. In reality, these can be symptoms of heartburn, but until now, in order to find out, a patient would have to wait in an emergency room and undergo at least six hours of testing, including blood tests and an EKG.

On the other hand, less than 50 percent of heart attack victims experience classic symptoms. Many people have atypical symptoms such as shoulder or stomach pain or exhaustion. By the time they  have finished with the classic tests, precious hours will have passed, which can lead to unnecessary heart damage and even heart failure

A blood test for cancer? Simple liquid biopsy could identify where in the body a tumor exists

'Liquid biopsies' are hoped to revolutionize cancer treatment, by identifying people with slow-growing tumors and those most in danger. They work by detecting the DNA released by dying tumor cells. Now, for the first time, US scientists can also pinpoint the part of the body affected. That is because the normal cells killed off by cancer also release DNA into the bloodstream, which has its own unique signature. A team from the University of California San Diego have found the DNA patterns for 10 different types of tissue, including from the liver, lung and kidneys.  Next step is a clinical trial.

Scientists Reverse Sickle Cell Disease for the First Time Using Gene Therapy

While this is just one case study involving a single French teenager, the early signs are encouraging, and the therapy could eventually lead to an effective treatment for the millions of people with this crippling disease worldwide. Sickle-cell disease occurs when one of the proteins making up a type of hemoglobin we use to carry oxygen through our body takes a slightly different form. This small change is enough to make the red blood cells they occupy lose elasticity, deforming them into a curved 'sickle' shape and risking clumps of cells piling up as they struggle to slip through blood vessels.

But by using a virus to insert genes for the correct form of this protein into the bone marrow of a French teenager, researchers have been able to restore the elasticity to the patient's blood cells.  After 15 months of therapy, the patient is off medication, and while it's far too early to say he's been functionally cured, it's a case of 'so far so good' for this pioneering kind of treatment.

In this case scientists removed bone marrow stem cells from the teen's body and added a specially made virus, designed to recode the cells to produce normal hemoglobin again. The cells were then transfused back into the patient. Doctors are reporting that half the patient's red blood cells are now regular and healthy, and he hasn't needed any blood transfusions since three months after his first treatment.

Heart failure Breakthrough: Stem cells trial offers hope to millions.

A method of repairing damaged heart muscles that have been scarred as a result of disease or earlier heart attacks has been called the “biggest breakthrough since transplants”. British scientists have found a way to use stem cells to repair damaged tissue which could help millions living with heart failure. The data, presented at the European Society of Cell and Gene Therapy in Florence, showed an average of 40 per cent reduction in heart damage in those on the treatment.  Next year global trials involving 500 people will begin.

New 'silver bullet' pill powered by your own stomach acid sends data straight to your phone while it works

A 'silver bullet' pill powered by your own stomach acid will send health data from inside your body to your phone.  It is believed the tiny pill could revolutionize medicine by constantly monitoring your health and administering medicine.  The pill powers up when a zinc electrode interacts with stomach acid.  Small sensors continually monitor temperature and heart rate and it administers medicine. The creation was unveiled at the world's biggest science conference in Boston

Bad Hospital Design Is Making Us Sicker  Evidence-based medical care will require evidence-based hospital design.

It’s no secret that hospital-acquired infections are an enormous contributor to illness and death, affecting up to 30 percent of intensive care unit patients. But housing patients together very likely exacerbates the problem. Research suggests that private rooms can reduce the risk of both airborne infections and those transmitted by touching contaminated surfaces. One study reported that transitioning from shared to private rooms decreased bacterial infections by half and reduced how long patients were hospitalized by 10 percent. Other work suggests that the increased cost of single-occupancy rooms is more than offset by the money saved because of fewer infections.  Installing easier-to-clean surfaces, well-positioned sinks and high-quality air filters can further reduce infection rates.

Falls in the hospital are another major problem, leading to serious injuries, longer hospital stays and significant costs. Trying to navigate the unfamiliar space of a hospital room, often while disoriented by pain and medications, makes many patients susceptible to falling. A number of design factors contribute: poorly lit areas, slippery floors, toilets that are too high or too low......And then there’s the problem of noise. The average noise level in hospitals far exceeds guideline-based recommendations, making it hard for patients to sleep. ....when it comes to recovering from illness, the more nature the better. But too often patients and physicians find themselves cooped up in dim rooms and sterile hallways with little access to natural light or views of nature: too much concrete, not enough jungle.
