Does Caffeine in Coffee Perk Up Heart Health?

Hey all you coffee lovers out there! There might a benefit from the coffee that you drink everyday. Research is studying the effects that coffee has on the heart. According to their recent research, scientist has seen that the caffeine in a cup of coffee might help your small blood vessels work better. So all of you who go to Starbucks every morning to get your cup of coffee might be having some extra benefits for your overall heart. For me, I think it is the sugar that increases blood flow through small vessels. 

WEDNESDAY, Nov. 20, 2013 (HealthDay News) -- Coffee seems to offer a mysterious benefit to heart health -- one that doctors have been at pains to explain.

Now, a small, new study from Japan suggests that the caffeine in a cup of coffee might help your small blood vessels work better, which could ease strain on theheart.

A cup of caffeinated coffee caused a 30 percent increase in blood flow through the small vessels of people's fingertips, compared with a cup of decaf, according to the research, which is scheduled for presentation Wednesday at the American Heart Association's annual meeting in Dallas.

These microvessels regulate the ease with which blood flows through the circulatory system and the body's tissues, said lead researcher Dr. Masato Tsutsui, a cardiologist and professor in the pharmacology department at the University of the Ryukyus, in Okinawa.

Previous studies have shown an association between coffee drinking and lower risk of heart attack, heart disease and stroke, said Dr. Gordon Tomaselli, chief of cardiology at the Johns Hopkins University School of Medicine. Researchers found that high doses of caffeine may improve the function of larger arteries.

But scientists have not been able to figure out why this is, given that coffee also can increase blood pressure. High blood pressure can damage arteries.

"This is an intriguing observation that may help us understand why consumption of coffee may be beneficial," said Tomaselli, former president of the American Heart Association.

The study involved 27 healthy adults, aged 22 to 30, who did not regularly drink coffee. They were asked to drink a 5-ounce cup of either caffeinated or decaffeinated coffee. Researchers then measured their finger blood flow using a noninvasive laser technique for gauging blood circulation.

Two days later, the experiment was repeated with the other type of coffee. Neither the researchers nor the participants knew when they were drinking caffeinated coffee.

The researchers found that blood flow in the small blood vessels improved by nearly one-third among the people who drank caffeinated coffee. The effect continued in those people over a 75-minute period.

Heart rate levels remained the same between the two groups, although caffeinated coffee slightly raised blood pressure.

The improved blood flow is likely because of improved function of the inner lining of the blood vessels, Tsutsui said. Researchers have linked the function of the lining of blood vessels -- also known as endothelial function -- to future heart attacks, heart disease and strokes.

By opening blood vessels and reducing harmful inflammation, caffeine may create favorable conditions for good heart health, he said.

But how much coffee is too much? Tsutsui pointed to a landmark U.S. National Institutes of Health study that showed that, overall, drinking six or more cups of coffee a day reduced men's risk of early death by 10 percent and women's risk by 15 percent.

That study, published last year in the New England Journal of Medicine, found that risk of heart disease and stroke either remained low or went even lower as people drank more coffee during the day.

The new study was co-sponsored by the All Japan Coffee Association, which might raise some healthy skepticism were it not for the large body of evidence that already shows coffee's heart health benefits, Tomaselli said.

That said, the study's small sample size does not conclusively explain why coffee is so good for the heart. "I don't think this answers any questions for us," Tomaselli said.

Data and conclusions presented at meetings typically are considered preliminary until published in a peer-reviewed medical journal.

Fighting fears possible during sleep, study shows

It is interesting to see that we can fight fears during sleep. Normally, phobia's are addressed by gradually showing that person the phobia they have little by little. It would be even better to fight fears during sleep because we are not fully aware of what is happening. I believe this can be potentially a great way to address fears and phobia especially starting from a young age. 

For many patients with phobias, typical treatment involves gradual exposure to the feared object or situation. But researchers have now found that emotional memory can be manipulated during sleep, paving the way to new phobia treatments as we dream.

The researchers, from Northwestern University, published the results of their study in the journal Nature Neuroscience.

They note that previous projects have demonstrated spatial learning and motor sequence learning can be strengthened during sleep, but until now, emotional memory has never been manipulated during slumber.

In the study, the researchers gave 15 healthy volunteers mild electric shocks while two different faces were presented to them. The volunteers also smelled different odorants - such as clove, new sneaker or mint - while looking at each face and being shocked.

This linked the face and the smells with fear for the volunteers, say the researchers.

As the subjects were sleeping, one of the odorants was released, but this time the faces and shocks were absent. The researchers released the odorant during slow wave sleep, which is when they say "memory consolidation" occurs.

After the subjects awoke, they were then shown both faces. However, when presented with the face linked to the odor they smelled during sleep, their fear levels were lower than when the saw the other face...

Modern Diet Is Rotting Our Teeth

I am not surprised to find out that our modern diet is rotting our teeth. Our diet now compared to back then has changed drastically. A lot of our foods now have been modified & have tons of unknown ingredients. The stuff we consume is heavily processed and modified and cannot be good for our oral health. Back when we used to be hunter-gathers, people never brushed their teeth or had good oral hygiene  The foods that they ate were not modified and processed. I believe there needs to be more research into the types of things that are put into our food and how it affects our oral health. 

A study of the evolution of our teeth over the last 7,500 years shows that humans today have less diverse oral bacteria than historic populations, which scientists believe have contributed to chronic oral diseases in post-industrial lifestyles.

The researchers, from the University of Adelaide's Australian Centre for Ancient DNA (ACAD), the University of Aberdeen (Dept of Archeology), Scotland, and the Wellcome Trust Sanger Institute, Cambridge, England, published their study in Nature Genetics.

The authors say that analyzing the DNA of calcified bacteria on the teeth of humans throughout modern and ancient history "has shed light on the health consequences of the evolving diet and behavior from the Stone Age to modern day".

The scientists explained that there were negative changes in oral bacteria as our diets altered when we moved from being hunter-gatherers to farmers. Further changes were observed when humans started manufacturing food during the Industrial Revolution....

Conjoined Twins are Successfully Separated in Dallas

It is amazing to see the miracle that doctors can perform today. Twins can be successfully separated without to much complications. It is cool to see how technology has changed and how much we can do with it now. 

Two conjoined infants have successfully been separated through an operation last Saturday, Dallas hospital officials confirmed.

Owen and Emmett Ezell were born conjoined from their breastbone to their hip bone. Before the surgery they shared a liver and an intestinal tract.

Five days after their surgery, the six-week-old infants are reported to be in stable condition at the Medical City Children's Hospital.

Dr. Clair Schwendeman, a neonatologist treating the twins, said he was "cautiously optimistic" for the twins' recovery.

"They're on some breathing support, but they've stabilized," said Schwendeman.

Schwendeman said incidents of conjoined twins are extremely rare and are estimated to occur at a rate of between one in 50,000 to one in 200,000 births. Depending on where the twins are conjoined, the survival rate for the infants is often extremely low.

Schwendeman said that the Ezell twins were estimated to have a 40 to 50 percent chance of survival.

The twins' mother, Jenni Ezell, has been writing about her experiences on her blog.

Writing about the morning of the surgery, Ezell wrote that she and her husband, Dave Ezell, had a few moments alone with the twins before they were taken away to the operating room.

"I hope I never have to experience a moment like that again," Ezell wrote. "I didn't know if I would see my babies alive again, if I would see only one, or if I would see them after they had gone to be with their creator."

At the Chiropractor, Well-Adjusted Pets

Wow I never thought that animals could go to chiropractor to get adjusted. But it does make sense because they do have bones like humans and sometimes those bones get miss-aligned. I have never been to a chiropractor myself, but would love to try it because I do feel like it will provide benefits in the long run. 

By ABBY ELLIN

One morning last August, Mary Arabe’s 9-year-old gray and black tiger cat, Leo, came home from a night out exploring with a severe limp and an elbow swollen three times its normal size. He was clearly in pain; Ms. Arabe thought he had dislocated his shoulder during a fall.

“He kind of lay around the barn that day; you could tell he was hurting,” said Ms. Arabe, who lives on a 25-acre farm in Rogers, Ohio, with 10 chickens, three horses, three cats and two dogs. “He was in so much agony I thought, ‘If someone can’t remove this animal’s pain I have to put him down.’”

She took Leo to the veterinarian, who said he could do nothing for him. Despondent, she took him to Rick Tsai, a chiropractor in Darlington, Pa., who a few years earlier had adjusted Ms. Arabe’s puggle, Bustar, after a head and neck injury.

An X-ray found no broken bones, but there was a large amount of swelling and fluid retention. Dr. Tsai couldn’t make any promises, but he placed his hands on the cat’s spine, hips and neck and manipulated the joints until they popped.

“We brought the cat home, and the next day he was walking fine,” said Ms. Arabe. “Two thirds of the swelling in the arm was gone. Whatever Dr. Tsai adjusted, it worked. He healed him.”

Millions of people swear by their chiropractors, and chiropractic has long been a mainstay in the equine world, especially among show or racehorses. Now it is gaining popularity among pet owners, as a way to treat household pets suffering from arthritis, sprains, joint pain and other ailments.

Animal, or veterinary, chiropractic originated around 1895, when human chiropractic first began. But it did not gain wider appeal until 1987, when the late Sharon Willoughby-Blake, a veterinarian and chiropractor, started Options for Animals in Hillsdale, Ill., which taught vets and chiropractors how to adjust animals. Two years later, the American Veterinary Chiropractic Association, a professional membership group and the main certifying agency in North America, was formed.

According to Robbie Hroza, vice president of operations for Options for Animals, about 2,000 students have gone through their program. Over the last two years, student enrollment has increased by 50 percent; a good portion are recent graduates of veterinary or chiropractic schools, she said.

Still, the practice remains controversial, in both people and pets. While some studies have found that chiropractic care can be more effective than medications for people with problems like neck pain, others have linkedforceful neck manipulation to strokes. Other researchers have found that unfavorable chiropractic outcomes are under-reported in medical trials.

There are only a few scientific studies about chiropractic’s efficacy on animals, and tensions exist both within and between the chiropractic and veterinary communities. The American Holistic Veterinary Medical Association, a trade organization, reports that in 2012 about 900 of the estimated 97,000 veterinarians in the United States practiced some type of animal adjustment.

In some states a chiropractor is not allowed to touch an animal without either a veterinarian’s referral or direct veterinary supervision. And in itspain management guidelines for dogs and cats, the American Animal Hospital Association and the American Association of Feline Practitioners caution, “chiropractic methods potentially can cause injury through the use of inappropriate technique or excessive force.”

“There is currently insufficient published evidence of efficacy in dogs and cats to make specific recommendations about the use of chiropractic intervention,” they add....Continue Reading

Indoor Tanning Remains Popular, Despite Risks

I can see why many women are getting addicted to tanning beds even with the risks of skin cancer. Women, most especially white women, like seeing their skin tan and will go through any measures to get tan skin. I've been to a tanning salon once and saw this white woman with her young daughter getting a tan at the salon. I could not believe that this mother would allow her daughter to get tan at a young age. It is because of pop culture that people think that "tan skin is the in thing" 

By ANAHAD O'CONNOR

Despite warnings about skin cancer, about a third of the young and adult white women in a new study said they used tanning beds, and many were using them frequently. Tanning beds are widely believed to have played a large role in the increasing rates of skin cancer in recent decades. The most serious type, melanoma, has risen sharply among young white women in particular.

The new study, published in the journal JAMA Internal Medicine, sought to document the prevalence of tanning bed use among white female high school students and white women ages 18 to 34.

It found that among the high school students, 30 percent had used a tanning bed in the previous year, and 17 percent had reported doing so at least 10 times, which was considered frequent use. Among those in the older group, a quarter had engaged in indoor tanning in the previous year, and 15 percent were classified as frequent users. In both groups, the practice was most common in the South and Midwest.

The authors of the report noted that indoor tanning before the age of 35 increases melanoma risk by up to 75 percent, and that the risk increases by roughly 2 percent with each additional tanning session per year.

Too Young to Have a Heart Attack

I was unaware that heart disease is the #1 killer of women until reading this post. I believe that younger people are having heart attacks because of the food they eat. The junk and fast food is not good for children growing up. Children should be eating vegetables and fruit and a well balance diet. It is sad to see families so busy now-a-days that they cannot prepare a proper meal. Instead, they take the easy route and go through a McDonalds drive thru for the convenience. 

By DIANE BENSON HARRINGTON

The foreshadowing escaped me: The night before we left for our summer vacation in Michigan, I accidentally stepped on my Kindle — which, like my heart, I cannot live without — and broke it. Reduced to reading novels on my iPhone, I made the best of it several days later, sitting in a sunroom overlooking Eight Point Lake, where my family gathers each year with friends.

The day before, proving to my teenage sons that 48 isn’t too old for fun, I had hung on for dear life as I zoomed behind a speedboat on a ski tube. The next day, I was enjoying a few moments of solitude in those blissful minutes before the sun goes down, finger-swiping to turn the page of my novel on my phone’s tiny screen, when my left arm started hurting.

You know that childhood feeling when your mother is mad at you, grabs your arm and squeezes it as she drags you away from whatever grief you’ve been causing? It felt like that, times 10, from shoulder to wrist. My chest got slightly uncomfortable, and I started sweating profusely. For the next four or five minutes, I kept to myself. I was incredibly antsy — up, down, sitting, standing, leaning, lying; my arm and I simply couldn’t get comfortable.

I instinctively knew what was happening but wasn’t ready to say it out loud, trying to reassure myself. There was no elephant on my chest; I’m too young – no one in my family has had heart trouble before age 55; I’m 50 pounds overweight but carry it well. Nevertheless, I motioned my husband up from the dock and, cradling my arm, told him something was really wrong.

He rushed to get some baby aspirin he’d seen earlier in the bathroom, which I chewed. I noticed him quietly doing a Google search for “heart attack symptoms” on his phone as family and friends gathered around us, but I was otherwise inside my head, no longer able to focus on what anyone else was doing or saying.

Our friend drove us to the E.R., where my EKG looked normal and the first nitroglycerin pill had no effect. But 10 minutes later, about the time the second and third nitro pill were making the pain dissipate, the doctor showed up with the result of my cardiac enzyme blood test. It’s supposed to be 0, but mine was much higher. And, he said, that weird somersault feeling I was having right at that moment at the base of my throat was actually tachycardia, a rapid heart rate. Before he was even done talking, an ambulance crew was waiting to take me to a bigger hospital 30 minutes away for a cardiac catheterization.

A little balloon angioplasty through the groin? I could deal with that, and maybe I could convince them to let me go back to the cottage in time for dessert. Instead, I woke up the next day, struggling to breathe, wrists strapped to the rails of a hospital bed, hearing the word “surgery.” I was extremely agitated, confused and unable to ask questions because of the breathing tube running down my throat.

This was not the summer vacation I had planned.

It turned out my “tortuous” left anterior descending artery was 95 percent clogged, and the angioplasty effort tore the inner artery wall, making a stent impossible and creating an even more critical situation. While I was still anesthetized, a surgical team was rounded up at 3 a.m. for an emergency heart bypass. In the span of a couple of hours, I went from expecting a teeny balloon in my artery and a little puncture in my groin to having open heart surgery and an eight-inch scar bisecting my chest.

Did I ever expect this? Not really. I’d read enough to know that heart disease is the No. 1 killer of women, that our heart attack symptoms often are radically different from men’s (just ask Rosie O’Donnell, whose heart attack symptoms the same week as mine seemed more like the flu), and that a third of cardiovascular-disease deaths happen to people younger than 65. But this stuff doesn’t happen to us, right?

Not only did it happen to me; it happened to me twice. I was lucky enough to arrange a flight home on a small plane — larger planes have pressure issues, and the doctors wouldn’t let us drive — but 30 minutes into the flight, my left arm started hurting and I started sweating, not to mention crying at the thought of going through this all over again.

We made an emergency landing. Later, after five hours of tests and discussion, a doctor told me it was stress-induced angina: the symptoms of a heart attack without the life-threatening blockage. He wanted me to stay overnight for observation, but finally agreed to let me continue my trip home.

I’d been relatively pain-free in the hospital, but once I was home, the agony of my titanium-twist-tied sternum was startling. I’ve had to take everything — shifting positions, showering, even breathing — slowly. I’m more aware of my heartbeat, which can be a little freaky. And while I won’t be running marathons any time soon, it’s heartening to hear from friends that I look “terrific,” nothing like a person who had a heart attack five months ago.

I’ve learned many things throughout all of this. Among them, that doctors now try to use a mammary artery, from the chest, for the bypass instead of grafting one from the leg because the mammary bypasses tend to last longer. And it’s likely that a lot of my previous complaints over the past few years — extreme fatigue, lack of endurance, poor circulation, jaw pain (not T.M.J., after all), and so many other vague symptoms — were due to this growing accumulation of plaque in my artery, not perimenopause. Even though I’m far from healed yet, I feel amazingly more alert and less muddled than I did before the surgery, and many of those other symptoms suddenly disappeared.

I also quickly learned I have more friends than I realized, as people brought dinners and well wishes for weeks on end (not to mention commiseration about trying to read a book on an iPhone, a heart-attack-inducing event if ever there was one). However, I’m still coming to terms with the idea of a heart-healthy diet here in Wisconsin, the land of aged and artisan cheeses.

Perhaps most important, I’ve learned to relinquish some control. Even if your doctor says you don’t need help walking up the stairs, let your husband or children escort you anyway. When you’ve been this close to death, the recovery is as much theirs as yours.
