MISSING 1-2 HOURS OF SLEEP HAVING DOUBLE THE CRASH RISK

Less sleep Driver's Got The More Probability Of Crash 

Hazards of drinking and driving, we all know only too well. But sleep deprived driving can be dangerous too! Did you know car crashes rank among the leading causes of death in the United States? Distracted driving can prove fatal. A new report compiled by the AAA Foundation for Traffic Safety, USA, points out that motorists, who miss just one to two hours of the required seven or more hours of sleep, nearly double their odds of a crash.

The report was based on data provided by the National Highway Traffic Safety Administration, and mined from police-reported crashes that involved a tow vehicle and/or an emergency medical response. Drivers involved in these incidents were asked how much sleep they had in the last 24 hours.

Not surprisingly, the AAA Foundation’s report found that the less sleep drivers got, the more their probability of a crash climbed: Those with only five to six hours of sleep under their belt were nearly twice as likely to crash, but drivers with only four or five hours of sleep risked four times the crash rate.

Sleep deprivation has several negatives: In addition to making us moody, it diminishes our productivity at work, it hurts our memory; weakens our immune system; and may increase our risk for obesity, cancer, and Alzheimer’s disease. Perhaps most dangerously, though, it causes cognitive impairment: One study found that subjects who hadn’t slept for 17 to 19 hours performed equivalent or worse on tests than if they had a blood-alcohol level of .05.

“You cannot miss sleep and still expect to be able to safely function behind the wheel,” Dr David Yang, the AAA Foundation for Traffic Safety’s executive director, said in a news release.

Unfortunately, a good portion of drivers on the road are likely to be sleep-deprived: 35 per cent of American adults sleep less than seven hours daily, according to a recent study conducted by the U.S. Centres for Disease Control and Prevention. Meanwhile, nearly one in three drivers admitted to the AAA Foundation that they “drove when they were so tired that they had a hard time keeping their eyes open” in the past month.

So, before you get into the car, pay less attention to how you feel physically, and instead think whether you got your seven or more hours. If you didn’t, consider taking public transit, contacting a cab or ride-sharing service, or taking a nap before you drive. As for longer road trips, avoid driving later at night, take regular breaks (every 100 miles or so), and have a companion in the passenger seat that will keep you awake and take over driving duties when you feel tired.

MEN WHO IS HAVING MORE SEXUAL PARTNERS ARE IN RISK OF PROSTATE CANCER

Having several sexual partners doubles prostate cancer risk in men

According to a new study, the more sexual partners a man has, the more like he is to get prostate cancer.

The study found that men who had more than seven sexual partners in their lifetime were twice as likely to have prostate cancer than those with fewer than three partners.

Men who are sexually active earlier may also be a risk, the researchers said:-

“The more partners you had, the more orgasms you had, the younger you were when you first had sex, all pointed to an increased prostate cancer risk,” Visalini Nair-Shalliker, doctoral student at Cancer Council New South Wales in Australia, was quoted as saying to smh.com.au.

It’s believed this increased risk associated with sexual activity could be due to hormonal changes.Sexual activity and metabolism were associated with antigen, a male sex hormone that is also strongly linked to the initiation of prostate cancer.

Other risk factors included having a father with a history of prostate cancer, a previous diagnosis of prostatitis or benign prostatic hyperplasia.

In addition, the study found that being overweight or obese was also associated with increased risk of the disease, but to a lesser extent.

There was no association found between prostate cancer risk and circumcision, vasectomy or erectile function, the researchers observed.

It is important to identify risk factors so men could be given advice, and men aged over 50 who fell into those risk categories should speak to their doctors, especially if they had a family history of the disease, Nair-Shalliker said.

However, “we can’t make any recommendations around sexual activity because it’s multi-faceted. We’re not saying ‘increase or decrease your sexual activity’ because the evidence is still grey about that,” Nair-Shalliker noted, in the paper published in the journal in the International Journal of Cancer.

WOMEN REMAIN SEXUALLY ACTIVE EVEN AFTER -70

surprising That Women remain sexually Active Even At Old Age! 

Older women remain sexually active beyond their seventh decade of life, a new study has found.

The study suggested that at least one in seven women aged 65 to 79 years has hypoactive sexual desire dysfunction (HSDD).

Although HSDD was found to be more common in women with partners, the study confirmed that unpartnered older women are still sexually active and may be distressed by low sexual desire.

For the study, published in the journal Menopause, the researchers took more than 1,500 women and assessed their sexual function and sexual distress.

The group consisted of 52.6% partnered women, with a mean age of 71 years. Within this group, 88% were found to have low sexual desire, 15.5% had sexually related personal distress and 13.6% had HSDD, which is defined as the presence of both low sexual desire and sexually related personal distress.

Independent factors included vaginal dryness during intercourse in the past month, having moderate to severe depressive symptoms, and having symptomatic pelvic floor dysfunction.

“This study demonstrates that healthcare providers need to have honest and open discussions with their patients as they age with regard to desire, mood, vaginal dryness, and pelvic floor issues to determine whether these factors are affecting a woman’s desire or ability to be sexual,” said JoAnn Pinkerton, Executive Director of the North American Medical Society.

TO PREVENT CANCER SPREAD CUT DOWN FAT

Want to prevent cancer spread? Cut down on fat

Spanish scientists announced Wednesday they may have identified a way to stop cancer from spreading, at least in mice, and said it could be linked to eating fat.

Writing in the journal Nature, the team said they had discovered a type of tumour cell which spreads cancer from organ to organ -- a process known as metastasis, which is what makes the disease so deadly. They also found that the cells carry a receptor, dubbed CD36, known to regulate the uptake of fats.

In experiments with mice given human tumours, metastasis was “significantly reduced” by using antibodies to block the CD36 receptor, the researchers said.

This worked for human mouth, skin and breast cancer.In some rodents, metastatic cells were completely wiped out, said the team, enthusing that “things like this don’t happen every day”.Receptors are protein molecules on cells which receive instruction-carrying chemical signals from outside.

In further tests, mice with CD36-rich cells and fed a high-fat diet developed more, and larger, metastases than their cousins on normal diets, the researchers said.Metastasis happens when cancer cells break free from a tumour and travel through the blood or lymphatic system to establish new colonies elsewhere in the body.

An estimated 90 percent of cancer deaths happen due to metastasis, the research team said.Not all cancer cells do this, however, and being able to identify and kill the ones that will travel is a top priority in cancer research.

The latest findings make CD36 a possible target for anti-cancer drugs, the researchers said.But they stressed the discovery was a “long way” from finding application in human medicine.The antibody used in the experiments does not yet exist in a format fit for human use.

Warning sign

“Ours is a new step that we hope in the future will not only contribute to our better understanding of how and why tumours generate metastasis, but also to devise ways to attack these metastatic cells,” study leader Salvador Aznar Benitah of the Institute for Research in Biomedicine in Barcelona told AFP.

“We are developing new blocking antibodies for human use that we hope to be able to test in a relatively short period of time (between four and ten years) in patients,” he explained by email.

WHITE WINE SIGNIFICANTLY INCREASE THE RISK OF CANCER

Save Yourselves From Risk Of Cancer

Drinking white wine may significantly increase the risk of invasive melanoma, a type of skin cancer, a new study has warned. About 3.6 per cent of cancer cases worldwide have been attributed to alcohol, most typically cancers of aerodigestive tract, liver, pancreas, colon, rectum and breast.

Previous research has suggested that alcohol can cause carcinogenesis as the ethanol in alcohol metabolises into acetaldehyde, which damages DNA and prevents its repair. Researchers at Brown University in the US used data from three large prospective cohort studies in which 210,252 participants were followed for a mean of 18.3 years, using food-frequency questionnaires to determine their alcohol consumption.

Overall alcohol intake was associated with a 14 per cent higher risk of melanoma per drink per day. Each drink per day of white wine was associated with a 13 per cent increased risk of melanoma. Other forms of alcohol – beer, red wine, and liquor – did not significantly affect melanoma risk.

The association between alcohol and melanoma was strongest for parts of the body that typically receive less Sun exposure. Eunyoung Cho, associate professor at Brown University said that compared with nondrinkers, those who consumed 20 grams or more of alcohol per day were two per cent more likely to be diagnosed with melanomas of the head, neck or extremities, but 73 per cent more likely to be diagnosed with melanomas of the trunk. She said this finding was novel and further research would be required to explain the results.

Cho said it was surprising that white wine was the only drink independently associated with increased risk of melanoma. The reason for the association is unknown. However, research has shown that some wine has somewhat higher levels of pre-existing acetaldehyde than beer or spirits.

While red and white wine may have similar amounts of pre-existing acetaldehyde, the antioxidants in red wine may offset the risks.

SUDDEN HEALTH PROBLEMS AFTER - 50

What May Be Happened After -50

One Minute You’re Fine …

When you’re past 50, some ailments can announce themselves suddenly and painfully. And aches and ouches you might not worry much about when you’re younger could be a sign of bigger problems in middle age.

Heart Attack

This is the big one: 735,000 people have one every year. A 50-year-old man has a 1 in 2 chance of getting heart disease at some point. The most common signs are chest pain, shortness of breath, and pain in your back, shoulders, or neck. You might also feel sweaty, dizzy, or like you’re going to throw up. Your risk is lower if you’re at a healthy weight, don’t smoke, and get regular exercise.

Aneurysm

Many of the lifestyle changes you make to lower your risk of heart disease and stroke can make you less likely to have this as well. An aneurysm happens when the wall of an artery gets weak and bulges outward. If that wall gives way, it can lead to serious internal bleeding or a stroke. Symptoms include pain, nausea, dizziness, clammy skin, and a rapid heartbeat.

Gallstones

These are hardened chunks of bile, a fluid that helps your body get rid of waste. They get stuck on the way out of your gallbladder, a small organ below your liver. They can range in size from a grain of sand to a golf ball and can cause severe pain in your upper belly or behind your belly button. You're more likely to get them if you’re obese, have diabetes or Crohn’s disease, or don’t exercise.

Acute Pancreatitis

Sometimes, gallstones can set this off. It’s inflammation of the pancreas, which makes enzymes and hormones like insulin that help with digestion. It causes severe stomach pain, nausea, vomiting, and a fever, and can be life-threatening. Seek medical help immediately if you have these symptoms. It also can be caused by heavy drinking, high levels of calcium, or a kind of fat called triglycerides.

Broken Bones

These can happen at any age, but your bones may become brittle as you get older and be more likely to break. A loss of bone is known as osteoporosis, and it's especially common in older women. Calcium and vitamin D can help slow it or stop it from getting worse, and certain drugs can help you keep bone, or even help you rebuild it.

Vertigo

If you suddenly find yourself dizzy, you might have vertigo. It can happen if tiny crystals in your inner ear, which help you control your balance, get moved around. You’re more likely to get it as you get older, probably because the crystals aren’t held in place as well. Your doctor can treat it with a series of head movements that move those particles back into place.

Pneumonia

People over 50 are at higher risk of the kind of pneumonia caused by bacteria, not the one caused by a virus. Called pneumococcal pneumonia, it can be life-threatening. Older people are more likely to get it because your body’s immune system gets weaker as you age. But there’s a vaccine for it, and the CDC recommends it for everyone over 65.

Detached Retina

Your retina is a light-sensitive layer in your eye that tells your brain what you see. If it pulls away from the outer wall of your eye, it won't get oxygen and other things it needs. You might see floating specks or flashes of light. You can permanently lose your eyesight, so see a doctor right away. It’s more common in people who are very nearsighted or have had cataract surgery or other eye diseases.

Spinal Stenosis

This develops slowly, but it can make itself known suddenly. It happens when the channel in your backbone that holds your spinal cord and other nerves narrows, usually because of arthritis. The nerves can be pinched or squeezed, causing pain, numbness, or cramps in your lower back or neck. It can be treated with drugs or physical therapy, or, in some cases, surgery.

Gout

This condition shows up as a sudden pain and swelling in one of your joints, often a big toe. It’s a form of arthritis caused by a buildup of uric acid in your body. If you take certain medications for high blood pressure, eat red meat and shellfish, and have more than two alcoholic drinks a day, you’re at higher risk. The soda sweetener known as fructose also raises your risk, and so does obesity.  

This is when a blood clot gets stuck in a blood vessel in one of your lungs. Your chances of having one go up after age 50, and it can be serious, so get medical help fast if you have chest pain, sudden shortness of breath, and dizziness. You also can have a bloody cough, leg pains, and clammy or bluish skin. The blood clot often starts in your leg, so an early sign might be swelling or pain in one of your calves.

Your risk goes up if you’ve had heart disease or recent surgery, or you were in a cramped position (like in an airplane or car) for a long stretch of time.

Kidney Stones

These are hard clumps, usually made of calcium, that form in your kidneys. They often pass harmlessly out of your body, but larger ones can be extremely painful and cause bleeding or infections or block the flow of urine. They’re more common in men than women. You can help prevent them by drinking plenty of fluids every day. Water is the best.
