PIKEVILLE, Ky. -- Speaking to a region with some of the nation's poorest health, the top federal public-health official gave examples of how individual communities and states have made themselves healthier.

"Health is not just about health, it's about society," Dr. Thomas Frieden, director of the Centers for Disease Control and Prevention, told more than 1,000 people at the Shaping Our Applalachian Region Innovation Summit in Pikeville. "Healthy societies are more productive, and productive societies are more healthy."

Referring to Kentucky's high rates of disease and factors that cause them, Frieden said bringing Eastern Kentucky's health statistics up to the national average would save more than 1,000 lives a year.

Frieden cited six communities that have tackled specific health issues, such as obesity, lack of physical activity, heart health, smoking and teen pregnancy.

Obesity is one of SOAR's three main health targets, but it's not an easy one, Frieden said. He said Somerville, Mass., reduced obesity in children under 6 by 21 percent by making it a community issue, with creation of farmers' markets for local produce, construction of walking paths and the mayor leading community walks.

"Physical activity is the closest thing to a wonder drug," Frieden said, because it helps prevent heart disease, strokes, diabetes and cancer, improved mood and lengthens life.

The leading preventable cause of death is smoking, Frieden said, calling for ordinances and laws making workplaces smoke-free. "Nobody should have to risk getting cancer to come to their job," he said.

Heart disease is the most preventable major cause of death, Frieden said, explaining how Minnesota and Grace Community Health Centers in Knox, Clay, Leslie and Bell counties have improved heart health by improving treatment of high blood pressure, or hypertension. "It's the single most important thing" to do for heart health, and it's simple, Frieden said, because the medicine is inexpensive and taken once a day with few if any side effects.

Frieden said the CDC thinks a lot about teen pregnancy because "Teen pregnancy perpetuates a cycle of poverty." He said Spartanburg, S.C., reduced teen pregnancy by 61 percent from 2001 to 2014 partly because South Carolina's Medicaid program paid for long-acting, reversible contraception immediately after delivery, and was the first state to give full reimbursement for post-partum insertion of intrauterine devices for birth control. Kentucky Medicaid doesn't cover such services.

Princess Health and One of every three U.S. adults have a combination of risk factors that increase their risk for heart disease and diabetes.Princessiccia

More than one-third of adults in the U.S. have a combination of health conditions that put them at higher risk of heart disease and diabetes, and this condition affects nearly half of adults aged 60 and older, according to a new study recently published in the Journal of the American Medical Association.

This combination of health conditions, when found in one person, is called metabolic syndrome. It includes abdominal obesity, high blood pressure, increased fasting glucose levels and abnormal cholesterol levels.

The study collected data gathered by the federal Centers for Disease Control and Prevention from adults 20 and older from 2003 to 2012. It found that about a third had a metabolic symdrome in 2011-12, and nearly half of those 60 and older did. Among those 20 to 39, the rate was 18 percent.

The study report says these were "concerning observations" because of the country's aging population. Hispanics, at 39 percent, were found to have the highest prevalence of metabolic syndrome among ethnic groups. Women had a higher prevalence than men in all age groups.

The American Heart Association says the best way to control the risk factors contributing to metabolic syndrome are to lose weight and increase physical activity. It also encourages patients to routinely monitor their weight, blood glucose, cholesterol and blood pressure and treat these risk factors according to established guidelines.

Princess Health andResearchers discover why common blood-pressure medicine doesn't work for some people: your kidneys don't want to lose salt.Princessiccia

Each year, more than 120 million prescriptions are written around the world for thiazide drugs, which lower salt to treat high blood pressure. High blood pressure affects 28 percent of Kentucky adults, according to the state Department for Public Health. Thiazide drugs often save lives but are ineffective in some patients and only work for a time in others. A study by University of Maryland School of Medicine researchers has found a key reason for the failure.

Thiazides prevent salt from moving through the kidney, causing it to expel salt and water. However, the researchers found that the kidney seems to know "that it's losing too much salt and activates mechanisms to retain salt in other ways," said Paul Welling, a professor of physiology at the University of Maryland.

The researchers studied an animal model designed to prevent salt retention, which imitated the thiazides' effects. They discovered almost 400 genes that alter their activity to assist regulation of the kidney's salt control. Eventually, it might be possible to make drugs that affect the body's mechanisms that control how the body interacts with thiazides.

Welling and his colleagues also may have discovered a "biomarker" that could allow doctors to easily find out in which patients thiazides will not work. When the kidney is working against the thiazides, a certain molecule increases in the urine. "Now that we know more about these novel pathways and processes, we can begin to find new ways to help patients with high blood pressure," said Dean E. Albert Reece, vice president for medical affairs at the University of Maryland.

Princess Health andStudy shows that removing a clot that causes a stroke leaves victims with higher functional independence.Princessiccia

Princess Health andStudy shows that removing a clot that causes a stroke leaves victims with higher functional independence.Princessiccia

In Kentucky, strokes cause about 5 percent of deaths, and the state had the 11th highest stroke mortality rate in 2009, according to data from the Kentucky Cabinet for Health and Family Services. Fewer than 40 percent of severe stroke victims regain functional independence if they get only the standard drug intervention, but a study has found that also removing the clot both helps restore blood flow to the brain and can lead to more favorable long term outcomes.

"The outcomes are the difference between patients being able to care for themselves after stroke and being dependent," said Demetrius Lopes, surgical director of the comprehensive stroke center at Rush University Medical Center.

The traditional treatment for ischemic stroke�a stroke that involves clots in vessels bringing blood to the brain�is intravenous tissue plasminogen activator (tPA), a medication to dissolve the clot. However, doctors can also perform thrombectomy, a minimally invasive procedure to remove the clot that is allowed only in clinical trials.

In the study, patients with severe ischemic strokes were split into two groups. One group received only tPA, while the other group received tPA as well as thrombectomy. After 90 days, those who received both treatments had less disability and had a functional independence rate of 60 percent, compared to 35.5 percent of those who received only tPA. Also, patients who received thrombectomy had better blood flow rates in the brain.

"Ethically, we can't deny patients a treatment when we have such strong evidence it's better for them," Lopes said. Now thrombectomy is a standard treatment for severe strokes at Rush and some other locations. The study is published in the online edition of the New England Journal of Medicine.

Princess Health and Princess Health andStudy concludes that fasting can reduce cholesterol levels for people in danger of developing diabetes.Princessiccia

Princess Health and Princess Health andStudy concludes that fasting can reduce cholesterol levels for people in danger of developing diabetes.Princessiccia

New research suggests that occasional fasting can help pre-diabetics from developing diabetes, which is more common in Kentucky than most states.

After 10 to 12 hours of fasting, the body looks for other energy sources to sustain itself, so it removes LDL (bad) cholesterol from fat cells and converts it into energyaccording to researchers at the Intermountain Heart Institute at Intermountain Medical Center in Murray, Utah.

"Fasting has the potential to become an important diabetes intervention," in addition to lifestyle changes and weight loss, said Benjamin Home, the lead researcher.

The study focused on prediabetics between the ages of 30 to 69 with at least three of the following metabolic risk factors: a large waistline, a high triglyceride (type of fat in the blood) level, a low HDL (good) cholesterol level, high blood pressure and high blood sugar after fasting.

"Over a six-week period cholesterol levels decreased by about 12 percent in addition to the weight loss," Home said. "Because we expect that the cholesterol was used for energy during the fasting episodes and likely came from fat cells, this leads us to believe fasting may be an effective diabetes intervention."

The removal of LDL cholesterol from the fat cells for energy use should help stop insulin resistance, which happens when the pancreas keeps producing more and more insulin until it can't make enough for the body, and the blood sugar rises. "The fat cells themselves are a major contributor to insulin resistance, which can lead to diabetes," he said. "Because fasting may help to eliminate and break down fat cells, insulin resistance may be frustrated by fasting."

Home noted that although fasting might be effective for protecting against diabetes, the results were not immediate. "How long and how often people should fast for health benefits are additional questions we're just beginning to examine." (Read more)

Princess Health and Small steps can prevent Kentucky's No. 1 killer, heart disease.Princessiccia

Princess Health and Small steps can prevent Kentucky's No. 1 killer, heart disease.Princessiccia

It is now February, which is American Heart Month and a perfect time to remind people that small steps can reduce their risk of heart disease, Kentucky's No. 1 killer.

You may be surprised to hear that almost 80 percent of heart disease is preventable and there are daily things that can be done to keep hearts healthy, according Dr. Martha Grogan, medical editor-in-chief of Mayo Clinic Healthy Heart for Life.

For example, try to move 10 extra minutes each day, Recent research shows a sedentary lifestyle may increase your risk of heart attack almost as much as smoking, said Grogan.

Each day, make an effort to get up from your desk to go talk to a colleague instead of sending an email, or walk around the house as you are talking on the phone, she recommends: �Moving even 10 minutes a day for someone who�s been sedentary may reduce the risk for heart disease by 50 percent.�

Hearts are also hurt when you deprive yourself of sleep, which is a necessity like food and water, said Virend Somers, a Mayo cardiologist and sleep expert. Chronic sleep deprivation can increase the risk of obesity, high blood pressure, heart attack, diabetes and depression.

Healthy habits can reduce a majority of risks for heart attack. "A 53-year-old male smoker with high blood pressure has a 20 percent chance of having a heart attack over the next 10 years. If he stops smoking, his risk drops to 10 percent; if he takes high blood pressure medicine, it falls to 5 percent," says preventive cardiologist Randal Thomas, M.D.

These healthy habits and changes like quitting smoking and taking blood pressure medicine can make a difference in life and death. For more from the Mayo Clinic, click here; for a American Heart Month information from the federal Centers for Disease Control and Prevention, go here.

Princess Health and Kentucky ranked sixth in nation for obesity, fourth in high blood pressure, second for diabetes.Princessiccia

A new report shows 29.5 percent of Kentuckians are obese, sixth highest in the nation. The state ranked second in the nation for the highest percentage of diabetes, with 13.7 percent of Kentucky residents diagnosed with the disease, and fourth in high blood pressure, at 36.3 percent.

According to the Gallup-Healthways Well-Being Index, West Virginia had the highest rates of obesity (35.3 percent),  diabetes (15.7 ) and high blood pressure (38.9) in the country. Colorado had the lowest, with 18.5, 6.8 and 22.6, respectively. Colorado "is the only state where fewer than 20 percent of adults are obese," reports Elizabeth Mendes for Gallup. West Virginia's obesity rate is the highest for any state since the study began in 2008.

The survey asked respondents if they had been diagnosed with diabetes or hypertension. to measure obesity, "participants were asked to report their height and weight, allowing Gallup to calculate their body mass index," reports The Huffington Post. A person with a BMI of 30 or higher is considered obese. (Read more)
