Healthy Swimming

Summer time means fun in the sun, and plenty of fun and games in the water - but did you know that germs could contaminate swimming water? Recreational water illnesses (RWIs) are spread by swimming in contaminated recreational waters such as: pools, water parks, lakes, and the ocean. Germs causing RWIs can be killed by chlorine, but it doesn't work right away. It takes time to kill germs, and some are resistant to chlorine and can live in pools for days. Here are some tips on how to protect yourself and your family from RWIs.

Swimmer's Ear

"Swimmer's Ear" is an infection of the ear and/or outer ear canal, which can cause the ear to itch or become red and inflamed. More common in children and young adults, movement or touching the ear can be extremely painful. Reduce your risk of getting Swimmer's Ear:

  • Dry your ears after swimming.
  • Check with the pool staff about the chlorine and pH-testing program at the pool. Those with good control are unlikely to spread Swimmer's Ear.
  • Avoid swimming in locations that may have been closed because of pollution.
  • Avoid putting objects (e.g. fingers, cotton swabs) in your ear that may scratch the ear canal and provide a site for infection.

Swimmer's Ear can be treated with antibiotic eardrops - contact your doctor if you think you might have Swimmer's Ear.

Swimmer's Itch

"Swimmer's Itch" is a skin rash caused by an allergic reaction to infection caused by certain parasites found in contaminated salt or fresh water. You may experience tingling, burning, or itching of the skin. Small reddish pimples may later occur and could develop into blisters. Swimmer's itch cannot be spread from person-to-person, and most cases do not require medical attention. If you have a rash - try not to scratch as this may cause the rash to become infected. You may try the following for relief:

  • Cool compresses
  • Anti-itch lotion; calamine lotion
  • Corticosteroid cream
  • Apply a baking soda paste to the rash

Children are more likely to be affected because they swim, wade, and play in the shallow water (where the parasites are most often found) more than adults, and they do not towel dry themselves when leaving the water. To reduce the risk of swimmer's itch:

  • Avoid swimming in areas where swimmer's itch is a known problem.
  • Do not attract birds by feeding them in areas where people are swimming.
  • Avoid swimming near or wading in marshy areas where snails are commonly found.
  • Towel dry or shower immediately after leaving the water.

Tips on Managing the Heat

Tips on Managing the Heat

The risk of heat exhaustion and heat stroke rises along with the temperature and humidity. Heat illnesses occur when the body's cooling mechanism becomes overloaded. When the heat starts to rise - slow down. Regardless of your activity level, drink more fluids - your body needs water to prevent dehydration during warm summer days. Stay away from liquids that contain caffeine, alcohol, or large amounts of sugar. Stay indoors or in shaded locations; wear lightweight, light-colored, loose-fitting clothing; and limit your outdoor activity to morning or evening hours when it is cooler outside.

Signals of Heat Emergencies

Heat exhaustion is a milder form of heat-related illness that can develop well after dehydration occurs. Those most prone to heat exhaustion include the elderly, those with high blood pressure, and children. Some symptoms of heat exhaustion include: cool, moist, pale or flushed skin; muscle cramps; heavy perspiring; nausea and sometimes vomiting; weakness; dizziness; dry mouth; and a headache.

Heat stroke is a life-threatening situation. It occurs when the body is unable to regulate its temperature. Heat stroke can occur within 10-15 minutes of the first symptoms. Signs of heat stroke include: very high body temperature (above 103 degrees); hot, dry, red skin; no sweating; nausea; dizziness; confusion, disorientation, hallucinations; or loss of consciousness.

Treatment of Heat Emergencies

If you feel you are suffering from heat exhaustion, it is important to get out of the sun and into a cool place; loosen clothing; drink water/fluids (be sure to avoid caffeine and alcoholic beverages); take a cool shower, bath or sponge bath; and rest.

Heat Stroke is a medical emergency - have someone call for immediate medical assistance while you begin cooling the victim. Get the person to a shaded area; cool him/her rapidly using whatever methods you can (immerse in a tub of cool water, place in a cold shower, spray with cool water from a garden hose); do not give fluids; if convulsions occur, keep the victim from injuring himself; call the hospital emergency room for further instructions if medical assistance is delayed in responding.

Start or stop the pill and hormones for reasons other than stable, and sometimes lead to hair loss. Hormone replacement therapy can have the same results. The presence of DHT is also the initiator of hair loss. DHT is a hormone that weakens hair follicles, and often causes hair loss.

Female Pattern Hair Loss



Female hair loss occurs in more than one pattern. If you are a woman with the loss of scalp hair, you should seek professional advice from a physician hair restoration specialist.

In most cases, can be female hair loss be treated effectively. If you are a woman had started to lose scalp hair, and you are not alone, if:

* You are unpleasantly surprised by the loss of hair

* You do not understand why you are losing hair

Patterns of hair loss in women can not be readily identifiable as is the case in men.
Unlike hair loss in men, female scalp has hair loss usually starts at any age through 50 or later, you may not have any clear relationship hereditary, and may not occur in recognizable “female pattern alopecia” to defuse the thin part above the the top of the scalp. A woman who notices the beginning of hair loss may not be sure whether the loss will be temporary or permanent, for example, if there was an event recently, such as pregnancy or diseases that may be associated with temporary hair thinning.

If you are a woman concerned about the loss of scalp hair, you should consult a physician hair restoration specialist for evaluation and diagnosis.
Self-diagnosis is often not effective. Women tend to be less obvious patterns of hair loss than men, and non-pattern hair loss is more common in women than in men. Diagnosis should be made ofhair loss in women should be made by a doctor trained and experienced.

In women as in men, and the likely cause of scalp hair loss is alopecia androgenetic – inherited sensitivity to the effects of androgens (male hormones) hair follicles in the scalp. However, women with hair loss due to this reason, usually do not grow true baldness in the patterns that occur in men, for example, they rarely put women in the cue “ball” appearance often seen in male pattern alopecia androgenetic.
Patterns of female androgenetic alopecia can vary considerably in terms of

appearance. Patterns that can occur as follows:

* Diffuse thinning of hair over the entire scalp, often with more noticeable thinning toward the back of the scalp.

* Osteoporosis is widespread over the entire scalp, with more noticeable thinning toward the front of the scalp but does not involve my hair in front of me.

* Osteoporosis is widespread over the entire scalp, with more noticeable thinning toward the front of the scalp, which in some cases, violation of my hair for me.

Unlike the case for men, thinning scalp hair in women due to androgenetic alopecia does not uniformly grow smaller in diameter (zoom out). Women with hair loss due to androgenetic alopecia tend to play down the hair Qatar variable on all the affected areas of the scalp. While miniaturization of hair is a feature of alopecia androgenetic, miniaturization may also be associated with other reasons, and not in itself a diagnostic feature of alopecia androgenetic. In women after menopause, for example, you may begin to reduce the size of the hair and it becomes difficult to style. It should be accurate diagnosis made by the physician hairrestoration specialist.

It is important to note that female pattern hair loss can begin as early as the late teens to early 20s at the time of the women who have experienced early puberty. If left untreated, this hair loss is associated with early puberty can progress to more advanced hair loss if left untreated.

However the pattern of causes of hair loss in women

Hair loss due to plucking the hair is usually incomplete, and the leaders of the hair-compulsive disorder tend to focus on the withdrawal in the selected areas. Hair loss because of this issue can not be addressed effectively until the psychological or emotional reasons for trichotillomania are effectively addressed.

Alopecia areata, a disorder which may cause loss of self is incomplete hair can range from diffuse thinning to extensive areas of baldness with “islands” of retained hair. Medical examination is necessary for the development of the diagnosis.
Triangular alopecia – Hair loss in time zones that sometimes begins in childhood. Hair loss can be complete, or a few fine, thin hair may remain in Qatar. The issue of triangular alopecia is not known, but in the case can be treated medically or surgically.

Scarring alopecia – Hair loss due to scarring of the scalp. Scarring alopecia typically involves the upper part of the scalp and occurs mostly in women. Condition often occurs in Americans of African descent, believed to be associated with persistent tight braiding or “corn-rowing” ofscalp hair. There is a form of scarring alopecia may also occur in women after menopause, associated with inflammation of hair follicles, and scarring later.

Telogen effluvium – a common type of hair loss caused when a large percentage of scalp hair is transformed into “shedding” phase. The causes of telogen effluvium may be hormonal, nutrition, and drug associated or stress-related. Loose anagen syndrome – a condition occurring primarily in people of fair hair whichscalp hair sits loosely in hair follicles and is easily extracted by combing or withdrawn. Case may appear in childhood, and can be improved and aged people. Diagnosis and treatment

Trauma Deadlier for Kids Without Insurance

Finding emphasizes need to fix U.S. health care, expert says

HealthDay

By Robert Preidt

Friday, November 6, 2009

HealthDay news imageTUESDAY, Nov. 3 (HealthDay News) -- Uninsured children in the United States are three times more likely to die from trauma injuries than children with private insurance, according to a new study.

Children with public insurance, such as Medicaid or the State Children's Health Insurance Program, were also slightly more likely to die as those with private insurance, the study found.

"We have this idea that everyone is treated equally, yet the mortality rate after trauma among uninsured children is much higher when compared to children with commercial insurance," Dr. Heather Rosen, a research fellow in plastic surgery at Children's Hospital Boston and Harvard Medical School and the study's lead researcher, said in a news release from the hospital.

The findings, published in the October issue of the Journal of Pediatric Surgery, stemmed from an analysis of National Trauma Data Bank information on 174,921 trauma patients aged 17 and younger.

The researchers suggested several possible reasons for the disparity they found:

  • Trauma patients with no insurance or public insurance might be transferred from one hospital to another, causing a delay in treatment.
  • Uninsured patients might be given fewer medical tests, leading to inadequate diagnoses or missed injuries.
  • If uninsured patients don't speak English, if it's not their native language, or if their education level is lower overall, they might have trouble talking to health-care providers about their medical history and quality of care after they were injured.

"This study suggests that there may be a direct effect of possessing insurance," Rosen said. "We need to work harder to get to the point where every person has access to health care in this country."

She noted that the federal Emergency Medical Treatment and Active Labor Act (EMTALA) requires all hospitals to treat patients until they're medically stable, regardless of insurance status.

"This paper provokes more questions than it answers," she said. "Should we be more vigilant about investigating whether EMTALA laws are being violated? Is this happening more often than we care to admit?"

Cooling May Reduce Brain Lesions in Newborns

Treatment after oxygen deprivation accounts for better motor skills later, study suggests

HealthDay

By Randy Dotinga

Friday, November 6, 2009

HealthDay news imageTHURSDAY, Nov. 5 (HealthDay News) -- Babies who are deprived of oxygen at birth often go on to have lifetime disabilities, but research has shown that cooling infants can help prevent problems.

Now, a new study reports that the cooling actually reduces the number of brain lesions in the babies.

Oxygen starvation at birth can cause a condition called hypoxic-ischemic encephalopathy, which can be fatal. Oxygen starvation also accounts for about 20 percent of cerebral palsy cases.

An earlier study found that chilling infants who suffer from oxygen deprivation can help reduce rates of cerebral palsy and improve their motor skills later in life. In the new study, reported online Nov. 5 and in the January issue of The Lancet Neurology, researchers investigated whether MRI scans would reveal fewer cerebral lesions in infants who were cooled.

That turned out to be the case. After reviewing MRI brain scans of 131 infants, they found 30 to 40 percent fewer lesions in areas of the brain where neurological development occurs. The infants who underwent cooling were three times more likely than those who didn't to have normal scans.

The scans also allowed doctors to predict with more than an 80 percent degree of certainty whether the infants would die or be disabled by the time they were 18 months old. The accuracy rate was 84 percent for the infants who were cooled and 81 percent for those who were not.

Calcium and Bone Health

Bones play many roles in the body. They provide structure, protect organs, anchor muscles, and store calcium. Adequate calcium consumption and weight bearing physical activity build strong bones, optimizes bone mass, and may reduce the risk of osteoporosis later in life.

For more information on bone health and osteoporosis please visit the National Osteoporosis Foundation.*

Peak Bone Mass

Peak bone mass refers to the genetic potential for bone density. By the age of 20, the average woman has acquired most of her skeletal mass. A large decline in bone mass occurs in older adults, increasing the risk of osteoporosis. For women this occurs around the time of menopause.

It is important for young girls to reach their peak bone mass in order to maintain bone health throughout life. A person with high bone mass as a young adult will be more likely to have a higher bone mass later in life. Inadequate calcium consumption and physical activity early on could result in a failure to achieve peak bone mass in adulthood.

Osteoporosis

Osteoporosis or "porous bone" is a disease of the skeletal system characterized by low bone mass and deterioration of bone tissue. Osteoporosis leads to an increase risk of bone fractures typically in the wrist, hip, and spine.

Section of bone showing osteoporosis

While men and women of all ages and ethnicities can develop osteoporosis, some of the risk factors for osteoporosis include those who are

  • Female
  • White/Caucasian
  • Post menopausal women
  • Older adults
  • Small in body size
  • Eating a diet low in calcium
  • Physically inactive

Calcium

Calcium is a mineral needed by the body for healthy bones, teeth, and proper function of the heart, muscles, and nerves. The body cannot produce calcium; therefore, it must be absorbed through food. Good sources of calcium include

  • Dairy products—low fat or nonfat milk, cheese, and yogurt
  • Dark green leafy vegetables—bok choy and broccoli
  • Calcium fortified foods—orange juice, cereal, bread, soy beverages, and tofu products
  • Nuts—almonds

Recommended amount of calcium vary for individuals. Below is a table of adequate intakes as outlined by the National Academy of Science.

Recommended Calcium Intakes

Ages Amount mg/day
Birth–6 months 210
6 months–1 year 270
1–3 500
4–8 800
9–13 1300
14–18 1300
19–30 1000
31–50 1000
51–70 1200
70 or older 1200
Pregnant & Lactating 1000
14–18 1300
19–50 1000

Vitamin D also plays an important role in healthy bone development. Vitamin D helps in the absorption of calcium (this is why milk is fortified with vitamin D).

For more information on calcium and children visit the National Institute of Child Health and Human Development (NICHD).

Weight-Bearing Physical Activity

Regular physical activity has been associated with many positive health benefits including strong bones. Like proper calcium consumption, adequate weight-bearing physical activity early in life is important in reaching peak bone mass. Weight-bearing physical activities cause muscles and bones to work against gravity. Some examples of weight bearing physical activities include

  • Walking, Jogging, or running
  • Tennis or Racquetball
  • Field Hockey
  • Stair climbing
  • Jumping rope
  • Basketball
  • Dancing
  • Hiking
  • Soccer
  • Weight lifting

Incorporating weight-bearing physical activity into an exercise plan is a great way to keep bones healthy and meet physical activity recommendations set forth in the Dietary Guidelines for Americans.

Adults: Engage in at least 30 minutes of moderate physical activity [on] most, preferably all, days of the week

Children: Engage in at least 60 minutes of moderate physical activity [on] most, preferably all, days of the week

Bone Health and Osteoporosis: A Surgeon General's Report
By 2020, one in two Americans aged 50 years or older will be at risk for fractures from osteoporosis or low bone mass.

Healthy Aging for old adults

Healthy Aging for Older Adults

The United States is on the brink of a longevity revolution. By 2030, the proportion of the U.S. population aged 65 and older will double to about 71 million older adults, or one in every five Americans. The far-reaching implications of the increasing number of older Americans and their growing diversity will include unprecedented demands on public health, aging services, and the nation’s health care system.


Chronic diseases exact a particularly heavy health and economic burden on older adults due to associated long-term illness, diminished quality of life, and greatly increased health care costs. Although the risk of disease and disability clearly increases with advancing age, poor health is not an inevitable consequence of aging.


Much of the illness, disability, and death associated with chronic disease is avoidable through known prevention measures. Key measures include practicing a healthy lifestyle (e.g., regular physical activity, healthy eating, and avoiding tobacco use) and the use of early detection practices (e.g., screening for breast, cervical, and colorectal cancers, diabetes and its complications, and depression).


Critical knowledge gaps exist for responding to the health needs of older adults. For chronic diseases and conditions such as Alzheimer's disease, arthritis, depression, psychiatric disorders, osteoporosis, Parkinson's disease, and urinary incontinence, much remains to be learned about their distribution in the population, associated risk factors, and effective measures to prevent or delay their onset.

Survey: Awareness of COPD – The Nation’s Fourth Leading Cause Of Death – Is Rising, But Understanding Is Still Low

Smokers and Those At Risk Far Less Likely To Talk To Their Doctor About Symptoms

Awareness of COPD — chronic obstructive pulmonary disease — continues to grow in the United States, according to national survey results released today by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health.

Sixty-eight percent of adults are now aware of COPD, a disease that affects 1 in 5 people over age 45, compared with 64 percent last year, and 49 percent in a 2004 survey. Among a high risk group, those who are currently smoking, awareness rose to 74 percent compared to 69 percent a year ago.

Less than half of all adults, 44 percent, understand that the disease can be treated. November is National COPD Awareness Month.

"Awareness is an important first step," said James P. Kiley, Ph.D., director, NHLBI Division of Lung Diseases. "However, awareness alone is not enough. People at risk of developing the disease need to know what the disease looks and feels like, and most importantly, to understand that it can be treated. The key is to get tested and start treatment as soon as possible."

COPD, which is sometimes referred to as chronic bronchitis or emphysema, is a serious lung disease affecting 24 million men and women in the United States. However, half of them remain undiagnosed despite recognizable symptoms such as shortness of breath while doing activities that used to be easy, wheezing, or chronic cough (sometimes called a "smoker’s cough") Eight out of 10 cases of COPD are due to smoking, typically affecting those over 40. The remaining cases are due to genetics or other environmental exposures.

The survey showed that physicians maintain an optimistic view about COPD treatability. Approximately 9 out of 10 primary care physicians agree that available treatments can optimize quality of life for their patients with COPD. However, the survey also showed that this message may not be familiar to their patients.

Symptoms of COPD were approximately two times more common among current smokers than former smokers, but current smokers are only half as likely to talk to their doctors about these symptoms. Survey results also showed that 41 percent of current smokers do not talk to their doctors about these symptoms because they do not want to hear another quit smoking message.

COPD is diagnosed with a simple noninvasive breathing test called spirometry, which can be conducted in a doctor's office. Taking the test involves breathing hard and fast into a tube connected to a machine which measures the total amount of air exhaled, called the forced vital capacity or FVC, and how much air is exhaled in the first second, called the forced expiratory volume in one second or FEV1.

"We know that for many people, taking the step to talk to a doctor about their smoking and symptoms is difficult," said Kiley. "But these actions, including testing of lung function, should be seen as proactive for better health."

The NHLBI analyzed the results of the annual HealthStyles and DocStyles surveys of the public health attitudes, knowledge, practices, and lifestyle habits of consumers and health care professionals, conducted each year by Porter Novelli, communications contractor for NHLBI's COPD Learn More Breathe Better campaign. The results represent a sample of 4,172 consumers through a mailed survey with a margin of error of plus or minus 1.5 percentage points and 1,000 physicians through a Web-based survey with a margin of error of plus or minus 3.1 percentage points. Both surveys were conducted in summer 2009.

The NHLBI initiated the first national awareness campaign on COPD, called the COPD Learn More Breathe Better campaign, in 2007 to improve knowledge about COPD among those already diagnosed and at risk for COPD, as well as health care providers — particularly those in a primary care setting. The program's new effort, Country Conquers COPD, aims to reach and raise knowledge of COPD among people at-risk at country-themed fairs and festivals across the country.

Part of the National Institutes of Health, the National Heart, Lung, and Blood Institute (NHLBI) plans, conducts, and supports research related to the causes, prevention, diagnosis, and treatment of heart, blood vessel, lung, and blood diseases; and sleep disorders. The Institute also administers national health education campaigns on women and heart disease, healthy weight for children, and other topics.

Clinical Tests Begin on Medication to Correct Fragile X Defect

NIH-supported scientists at Seaside Therapeutics in Cambridge, Mass., are beginning a clinical trial of a potential medication designed to correct a central neurochemical defect underlying Fragile X syndrome, the most common inherited cause of intellectual disability. There has to date been no medication that could alter the disorder’s neurologic abnormalities. The study will evaluate safety, tolerability, and optimal dosage in healthy volunteers.

The work is the outcome of basic research that traced how an error in the fragile X mental retardation gene (FMR1) leads to changes in brain connections, called synapses. The changes in turn appear to be the mechanism for learning deficits in Fragile X syndrome. The new trial tests Seaside Therapeutics’ novel compound, STX107, that selectively and potently targets the synaptic defect.


Thomas R. Insel, M.D., director of the National Institute of Mental Health, said, "This project is the culmination of years of fundamental research, first identifying the genetic mutation and later deciphering the biochemical consequences of this mutation. Now, with the initiation of this first clinical study, we move one step closer to understanding how this novel candidate may play a critical role in improving the lives of individuals with Fragile X Syndrome."


Randall Carpenter, M.D., president and chief executive officer of Seaside Therapeutics, and Mark Bear, Ph.D., Seaside’s scientific founder, are leading the research. Dr. Bear is a Howard Hughes Medical Institute investigator and a professor of neuroscience at the Massachusetts Institute of Technology, Cambridge, Mass.


The National Institute of Mental Health, the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), and the National Institute of Neurological Disorders and Stroke (NINDS) have provided grant support. Private foundations providing funding include the advocacy groups Autism Speaks and FRAXA Research Foundation.


Fragile X syndrome is the most common inherited cause of intellectual disability, affecting an estimated 1 in 4,000 males and 1 in 6,000 females.


The syndrome causes a range of developmental problems, including learning disabilities and cognitive impairment. People with Fragile X syndrome may have anxiety and attention deficit hyperactivity disorder. About one-third of males with Fragile X syndrome also have autism or autistic-like behavior that affects communication and social interaction. Usually, males, who have only a single X chromosome, are more severely affected than females.


People with Fragile X have DNA mutations in the FMR1 gene that, in effect, turn off the gene. Research in recent years by Dr. Bear and colleagues has identified the molecular consequences of this silencing of FMR1. Normally, the protein product of the FMR1 gene acts to dampen the synthesis of proteins at synapses that are stimulated via a specific class of receptors on brain cell — metabotropic glutamate receptors (mGluRs). Without the brake provided by FMR protein, synaptic protein synthesis is excessive and connections do not develop normally.


This basic research provided the basis on which to develop medications that could correct the defect.


The current study will focus on a compound, designated STX107, that selectively inhibits one type of mGluR receptor, mGluR5. Evidence in mice with Fragile X-like symptoms suggests that reducing levels of mGluR5 can restore normal synaptic protein synthesis and improve function.


The initial phase 1 study of STX107 will involve healthy volunteers. If results suggest that the medication is safe and tolerable, the study will progress to a phase 2 test of dosage and efficacy in adults with Fragile X syndrome. If STX107 shows promise in adults, the compound will be assessed for pediatric safety (with funding from the Best Pharmaceuticals for Children Act [http://bpca.nichd.nih.gov/about/index.cfm] through NICHD) prior to initiating clinical trials in children.

NIH-Supported Trial to Study Testosterone Therapy in Older Men

Low serum testosterone may contribute to a number of problems affecting older men, including decreased ability to walk, loss of muscle mass and strength, decreased vitality, decreased sexual function, impaired cognition, cardiovascular disease and anemia. While testosterone normally decreases with age, in some men, low levels of testosterone may contribute to these debilitating conditions. A new national clinical trial will test whether these conditions can be favorably affected by testosterone therapy.


The National Institute on Aging (NIA), part of the National Institutes of Health, today announced the start of a large-scale clinical trial to evaluate the effect of testosterone therapy on older men. Led by the University of Pennsylvania School of Medicine and conducted at 12 sites across the nation, the Testosterone Trial will involve 800 men age 65 and older with low testosterone levels.


"We know that, as men get older, a significant proportion are unable to carry out activities of daily living and experience decreased physical and cognitive function and decreased independence," said NIA Director Richard J. Hodes, M.D. "We do not know the extent to which low levels of testosterone may contribute to these conditions."


A 2004 report by the Institute of Medicine, "Testosterone and Aging: Clinical Research Directions," noted several important unanswered questions about the effects of testosterone therapy. The NIA is aiming to answer these questions by testing the effectiveness of testosterone therapy in older men with low testosterone levels and one of the following conditions: impaired walking, low vitality, sexual or cognitive dysfunction. A key consideration is the use of testosterone as a therapy for certain conditions, rather than as a preventive measure.


The NIA is the primary source of support for this trial. Additional funding is being provided by the National Heart, Lung, and Blood Institute (NHLBI); the National Institute on Neurological Disorders and Stroke (NINDS); the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) and Solvay Pharmaceuticals, which is also supplying the study drug.


The Testosterone Trial will include five separate studies. At each of the 12 sites, men 65 and older with low serum testosterone and at least one of the following conditions — anemia, decreased physical function, low vitality, impaired cognition or reduced sexual function — will be randomly assigned to participate in a treatment group or a control group. Treatment groups will be given a testosterone gel that is applied to the torso, abdomen, or upper arms; control groups will receive a placebo gel. Serum testosterone will be measured monthly for the first three months and quarterly thereafter up to one year. Participants will be tested on a wide range of measures to evaluate physical function, vitality, cognition, cardiovascular disease, and sexual function.


"This study is important because testosterone products have been marketed for many years as treatments for a variety of conditions," said Evan C. Hadley, M.D., director of NIA’s Division of Geriatrics and Clinical Gerontology, which is the primary funder of the trial. “"We hope this trial will establish whether testosterone therapy results in clear benefits for older men."


The University of Pennsylvania School of Medicine is the lead institution for the trial and will serve as coordinating center for the study sites. Peter J. Snyder, M.D., professor of medicine in the Division of Endocrinology, Diabetes and Metabolism at Penn, is the principal investigator and will oversee trial activities. "This is an unprecedented opportunity for older men to learn more about themselves and at the same time help find out if testosterone will improve some of the afflictions of old age," said Dr. Snyder.


Recruitment of study participants will begin in November of 2009. Men age 65 and older who are interested in participating should call the site closest to them. Men living within a 50-mile radius of the study centers, listed below, are especially encouraged to participate.

    Researchers Develop Innovative Imaging System to Study Sudden Cardiac Arrest

    NHLBI Recovery Act Funds Will Advance Understanding, Could Lead to Exploration of Potential New Treatments

    A research team at Vanderbilt University has developed an innovative optical system to simultaneously image electrical activity and metabolic properties in the same region of a heart, to study the complex mechanisms that lead to sudden cardiac arrest. Tested in animal models, the system could dramatically advance scientists' understanding of the relationship between metabolic disorders and heart rhythm disturbances in humans that can lead to cardiac arrest and death, and provide a platform for testing new treatments to prevent or stop potentially fatal irregular heartbeats, known as arrhythmias.


    The research is supported in part by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health.


    The design and use of the dual camera system is described in the Nov.1 issue of Experimental Biology and Medicine. Additional support for the project has also been provided by the Vanderbilt Institute for Integrative Biosystems Research and Education (VIIBRE), the American Heart Association, and the Simons Center for Systems Biology at the Institute for Advanced Study.


    "The challenge in understanding cardiac rhythm disorders is to discern the dynamic relationship between multiple cardiac variables," said one of the coauthors of the paper and the project's principal investigator, John P. Wikswo, Ph.D., Gordon A. Cain University Professor and VIIBRE director. "This dual camera system opens up a new window for correlating metabolic and electrophysiological events, which are usually studied independently."


    The 11-year-old research project would have been terminated this year due to lack of funding, according to Wikswo. But a $566,000 American Recovery and Reinvestment Act grant from the NHLBI is enabling the 13-member research team to continue developing and testing the innovative optical system. Recovery Act funds are also allowing the team to purchase a pair of $60,000 high-speed and highly sensitive digital cameras to record the changes in the metabolic and electrical activity of isolated cardiac tissue using low-intensity fluorescent dyes under conditions associated with heart failure, ischemia, fibrillation and other pathological circumstances.


    "Through the Recovery Act, the NHLBI is able to support promising research to develop and enhance innovative technologies to help us better understand the complex mechanisms involved in potentially fatal conditions such as sudden cardiac arrest," said NHLBI Director Elizabeth G. Nabel, M.D. "This research will allow us to better understand how to prevent and treat life-threatening cardiac rhythm disturbances and potentially save thousands of lives every year."


    Each year, 250,000 to 450,000 people die in the United States as a result of sudden cardiac arrest, a condition that is triggered by arrhythmia. Usually, a complex series of electrical and metabolic changes precede sudden cardiac arrest.


    The Vanderbilt researchers created and tested an innovative way to visualize the electrical activity of the heart in relation to its structure and changing metabolic state under different pathological conditions. Their multimodal cardiac imaging technique uses a two-camera approach to integrate electrophysiological imaging with optical fluorescence imaging of metabolic activity associated with damaged heart tissue and tachycardia, or accelerated heart rate. The biochemical and electrochemical studies of heart tissue under controlled conditions will enhance scientists' understanding of electrometabolic cardiac disorders and their clinical treatment.


    The advantages of this imaging system over others include rapid setup, two-color image separation, high spatial resolution, and an optional software camera calibration routine that eliminates the need for precise camera alignment. The authors provide a detailed description of a camera calibration procedure along with multiple examples.


    In addition, the multimodal imaging system will be a less-invasive, instrumental tool in helping scientists discover and test safe and effective ways to prevent or treat arrhythmias. Current treatments include medications that can produce undesirable side effects and the implantable cardioverter defibrillator, a small device that’s placed under the skin in the chest and uses electrical pulses or shocks to help control life-threatening arrhythmias.

    NIH-Funded Researchers Transform Embryonic Stem Cells Into Human Germ Cells

    Advance Provides Potential Tool to Find Causes of Unexplained Infertility, Birth Defects

    Researchers funded in part by the National Institutes of Health have discovered how to transform human embryonic stem cells into germ cells, the embryonic cells that ultimately give rise to sperm and eggs. The advance will allow researchers to observe human germ cells — previously inaccessible — in laboratory dishes.

    "This achievement opens a new window into what was only recently a hidden stage of human development," said Susan B. Shurin, M.D., acting director of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), the NIH Institute that provided funding for the study. "Laboratory observation of human germ cells has the potential to yield important clues to the origins of unexplained infertility and to the genesis of many birth defects and chromosomal disorders."

    The results were published online in Nature on Oct. 28.

    The study was conducted by Kehkooi Kee, Vanessa T. Angeles, Martha Flores, Ha Nam Nguyen and Renee A. Reijo Pera, all of Stanford University School of Medicine.

    Researchers have long sought to understand the process by which cells in the early human embryo mature into germ cells, explained Dr. Reijo Pera, the study’s senior author. But studying this process in human beings has been impossible in the past, because it takes place so early in development — before the embryo is two weeks old.

    Dr. Reijo Pera explained that the ability to observe germ cells in laboratory cultures opens up several promising new avenues of research. Although infertility is apparent only after sexual maturity, she said, many forms of unexplained infertility are thought to have their origins in errors that occur in the cells of the early embryo. The ability to observe embryonic germ cells as they develop may allow researchers to pinpoint potential genetic changes underlying infertility. According to the Centers for Disease Control and Prevention, infertility is a major health problem that costs the United States more than $5 billion annually.

    The researchers began with human embryonic stem cells, to which they added a gene that makes a protein which flashes green when a gene found only in germ cells is turned on. After the embryonic stem cells grew and changed for two weeks, the researchers isolated the cells that flashed green.

    The researchers next conducted a variety of tests to confirm that the green fluorescing cells behaved like germ cells. Once convinced that their cells were in fact germ cells, the researchers turned on and off several candidate genes to see if those genes played a role in the development of stem cells into immature germ cells. The three genes they tested are named DAZ, DAZL and BOULE, and all come from the same family of genes. Dr. Reijo Pera discovered the first of them, DAZ (Deleted in AZoospermia), in the mid-1990s, when she showed that infertile men who lack germ cells often lack the gene.

    In the new study, she and her colleagues showed that DAZL was necessary to transform embryonic stem cells into germ cells. When DAZL was turned off, just half as many germ cells formed. DAZ and BOULE, by contrast, acted later in the germ cells' maturation, nudging the cells into a phase called meiosis, during which cells reduce their number of chromosomes by half.

    The researchers even observed that some male germ cells went all the way through the process of meiosis, to the point where they had half as much genetic material as they had begun with. They did not stimulate female germ cells to progress through meiosis because female human germ cells pause partway through meiosis and remain in that state for many years, through sexual maturity.

    Dr. Reijo Pera next plans to try the same techniques with so-called induced pluripotent stem cells. Induced pluripotent cells are adult cells that have been reprogrammed to behave like embryonic cells. If it works, she hopes to take cells from an adult with infertility, transform them into germ cells and study them for clues to the cause of the adult's infertility.

    Migraine With Aura Can Double Stroke Risk

    Young women who smoke and use birth control pills are most susceptible, researchers say

    HealthDay



    Tuesday, October 27, 2009

    HealthDay news imageTUESDAY, Oct. 27 (HealthDay News) -- Women who get migraine headaches with aura should stop smoking and using birth control pills because they may increase their risk of stroke, researchers say.

    For people who suffer migraine headaches with aura -- visual disturbances before or during the migraine -- the risk for ischemic stroke is doubled, they found. Being female, under 45, smoking and using oral contraceptives that contain estrogen added to the risk.

    Ischemic stroke is caused by a blockage in a blood vessel. The connection between migraine and stroke was already suspected. What was unknown was the extent of risk and who is most at risk, the researchers said.

    Migraine headaches affect up to 20 percent of the population. Women are up to four times more likely than men to get migraines, and as many as one third also experience an aura before or during a migraine.

    "Migraine with aura is associated with a twofold increased risk for ischemic stroke compared to people without migraine, while migraine without aura does not appear to change the risk," said lead researcher Dr. Markus Schurks, from the division of preventive medicine at Brigham and Women's Hospital in Boston.

    "But, considering the low absolute risk, there is no reason to panic, but modifiable risk factors such as smoking and oral contraceptive use should be considered," he said.

    The report is published in the Oct. 27 online edition of the British Medical Journal.

    For the study, Schurks and colleagues analyzed nine studies concerning the association between migraine, with and without aura, and cardiovascular disease.

    "The risk appears to be highest among women with migraine with aura who smoke and use oral contraceptives," Schurks said.

    In contrast, migraine alone does not appear to alter the risk for heart attack and death from cardiovascular disease, he added.

    "In the scheme of things, aura is just one among many potential risk factors for stroke, so it is important to put this in context," said Dr. Elizabeth Loder, chief of the division of headache and pain at Brigham and Women's Hospital and author of an accompanying journal editorial.

    "The risk of stroke for most people with migraine is low -- stroke is an uncommon event -- and so a doubling of that low baseline risk is not cause for alarm," she said. "Although it's not a reason for panic, having aura is a reason to pay extra attention to other stroke risk factors that can be modified. These include high blood pressure, high cholesterol, smoking and use of estrogen-containing contraceptives."

    Other experts agreed.

    Dr. Vincent Martin, an associate professor of medicine at the University of Cincinnati, said that "we have always known that the risk of stroke increased in patients with migraine, but this clarifies the situation in terms of which groups of migrainers are at more risk."

    "If you are a female and you've got migraine with aura, you really need to be careful about managing your risk factors for stroke, because your risk for stroke is increased," he said. Smoking and birth control pills just aren't a good idea, he added.
