In The USA Scientists Have Found The New Causes Of Glaucoma

In The USA Scientists Have Found The New Causes Of Glaucoma.
Glucosamine supplements that millions of Americans select to balm treat up on and knee osteoarthritis may have an unexpected side effect: They may increase risk for developing glaucoma, a scanty new study of older adults suggests in May 2013. Glaucoma occurs when there is an proliferation of intraocular pressure (IOP) or pressure inside the eye. Left untreated, glaucoma is one of the unsurpassed causes of blindness.

In the new study of 17 people, whose average age was 76 years, 11 participants had their optic pressure measured before, during and after taking glucosamine supplements. The other six had their liking pressure measured while and after they took the supplements. Overall, pressure inside the sidelong glance was higher when participants were taking glucosamine, but did return to normal after they stopped taking these supplements, the study showed.

So "This swatting shows a reversible effect of these changes, which is reassuring," wrote researchers led by Dr Ryan Murphy at the University of New England College of Osteopathic Medicine in Biddeford, Maine. "However, the likelihood that constant damage can result from prolonged use of glucosamine supplementation is not eliminated. Monitoring IOP in patients choosing to extend with glucosamine may be indicated".

Exactly how glucosamine supplements could affect power inside the eye is not fully understood, but several theories exist. For example, glucosamine is a harbinger for molecules called glycosaminoglycans, which may elevate eye pressure. The findings are published online May 23 as a delving letter in JAMA Ophthalmology.

People Often Die In Their Sleep

People Often Die In Their Sleep.
People with doze apnea and hard-to-control drunk blood pressure may see their blood pressure drop if they treat the catnap disorder, Spanish researchers report. Continuous positive airway pressure (CPAP) is the orthodox treatment for sleep apnea, a condition characterized by disrupted breathing during sleep. The drop disorder has been linked to high blood pressure. Patients in this study were taking three or more drugs to tone down their blood pressure, in addition to having sleep apnea.

Participants who used the CPAP device for 12 weeks reduced their diastolic blood compel (the bottom number in a blood pressure reading) and improved their overall nighttime blood pressure, the researchers found. "The popularity of sleep apnea in patients with uncompliant high blood pressure is very high," said lead researcher Dr Miguel-Angel Martinez-Garcia, from the Polytechnic University Hospital in Valencia. "This forty winks apnea therapy increases the probability of recovering the normal nocturnal blood pressure pattern.

Patients with resistant great in extent blood pressure should undergo a sleep study to rule out obstructive sleep apnea, Martinez-Garcia said. "If the resolute has sleep apnea, he should be treated with CPAP and undergo blood compression monitoring". The report, published in the Dec 11, 2013 issue of the Journal of the American Medical Association, was partly funded by Philips-Respironics, maker of the CPAP combination used in the study.

The CPAP organized whole consists of a motor that pushes air through a tube connected to a mask that fits over the patient's announce and nose. The device keeps the airway from closing, and thus allows interminable sleep. Sleep apnea is a common disorder. The pauses in breathing that patients know-how can last from a few seconds to minutes and they can occur 30 times or more an hour.

Cardiologists Recommend To Monitor Blood Pressure

Cardiologists Recommend To Monitor Blood Pressure.
Fewer commoners should bear medicine to control their high blood pressure, a new set of guidelines recommends. Adults superannuated 60 or older should only take blood pressure medication if their blood pressure exceeds 150/90, which sets a higher sandbank for treatment than the current guideline of 140/90, according to the report, published online Dec 18, 2013 in the Journal of the American Medical Association. The virtuoso panel that crafted the guidelines also recommends that diabetes and kidney patients younger than 60 be treated at the same period as Dick else that age, when their blood pressure exceeds 140/90.

Until now, people with those chronic conditions have been prescribed medication when their blood persuasion reading topped 130/80. Blood pressure is the might exerted on the inner walls of blood vessels as the heart pumps blood to all parts of the body. The more elevated reading, known as the systolic pressure, measures that force as the heart contracts and pushes blood out of its chambers. The discount reading, known as diastolic pressure, measures that constrain as the heart relaxes between contractions.

Adult blood pressure is considered normal at 120/80. The recommendations are based on clinical validation showing that stricter guidelines provided no additional advantage to patients, explained guidelines author Dr Paul James, head of the department of dynasty medicine at the University of Iowa Carver College of Medicine. "We really couldn't walk additional health benefits by driving blood pressure lower than 150 in people over 60 years of stage ".

And "It was very clear that 150 was the best number". The American Heart Association (AHA) and the American College of Cardiology (ACC) did not analysis the new guidelines, but the AHA has expressed reservations about the panel's conclusions. "We are active that relaxing the recommendations may expose more persons to the fine kettle of fish of inadequately controlled blood pressure," said AHA president-elect Dr Elliott Antman, a cardiologist at Brigham and Women's Hospital and a professor at Harvard Medical School in Boston.

In November, the AHA and ACC released their own seam set of therapy guidelines for high blood pressure, as well as inexperienced guidelines for the treatment of high cholesterol that could greatly expand the number of race taking cholesterol-lowering statins. About one in three adults in the United States has high blood pressure, according to the US National Heart, Lung, and Blood Institute. The introduce formed the Eighth Joint National Committee, or JNC 8, in 2008 to update the termination set of high blood demand treatment guidelines, which were issued in 2003.

In June 2013, the institute announced that it would no longer participate in the condition of any clinical guidelines, including the blood pressure guidelines nearing completion. However, the disclosure came after the institute had reviewed the preliminary JNC 8 findings. The JNC 8 solid to forge ahead and finish the guidelines.

A New Method For Treating Stubborn Hypertension

A New Method For Treating Stubborn Hypertension.
A romance access to blast away kidney nerves has a striking effect on lowering blood pressure in mettle patients whose blood pressure wasn't budging despite trying multiple drugs, Australian researchers report. Although this sanctum only followed patients for a short time - six months - the authors put faith the approach, which involves delivering radiofrequency energy to the so-called "sympathetic " nerves of the kidney, could have an cause on heart disease and even help lower these patients' hazard of death. The findings were presented Wednesday at the annual meeting of the American Heart Association in Chicago and published simultaneously in The Lancet.

The swat was funded by Ardian, the company that makes the catheter emblem used in the procedure. "This is an extremely important study, and it has the potential for honestly revolutionizing the way we deal with treatment-resistant hypertension," said Dr Suzanne Oparil, director of the Vascular Biology and Hypertension Program at the University of Alabama at Birmingham. Oparil spoke at a message bull session Wednesday to announce the findings, though she was not involved in the study.

Treatment-resistant blood pressure, defined as blood press that cannot be controlled on three drugs at full doses, one of which should be a diuretic, afflicts about 15 percent of the hypertensive population. "Many patients are wild on four or five drugs and have truly refractory hypertension. If it cannot be controlled medically, it carries a extreme cardiovascular risk".

This radioablation procedure had already successfully prevented hypertension in unrefined models. According to study author Murray Esler, the symbol specifically targets the kidneys' sympathetic nerves. Previous studies have indicated that these nerves are often activated in vulnerable hypertension a cardiologist and scientist at the Baker IDI Heart and Diabetes Institute in Melbourne, Australia.

Americans Suffer High Blood Pressure

Americans Suffer High Blood Pressure.
High blood press is a preventable and treatable danger factor for heart attack and stroke, but about one-quarter of adults don't recollect they have it, according to a large new study. Among those who do know they have the condition, many are not likely to have it under control, said persuade researcher Dr Uchechukwu Sampson, a cardiologist at Vanderbilt University Medical School in Nashville. "Despite all the going forward we have made in having available treatment options, more than half of the proletariat we studied still have uncontrolled high blood pressure.

The study is published in the January issue of the minute-book Circulation: Cardiovascular and Quality Outcomes. One in three US adults has high blood pressure, according to the US National Heart, Lung, and Blood Institute. Any reading over 140/90 millimeters of mercury is considered elated blood pressure. The analyse findings coincided with the Dec 18, 2013 issuing of immature guidelines for blood pressure management by experts from the institute's eighth Joint National Committee.

Among other changes, the unique guidelines recommend that fewer family take blood pressure medicine. Older adults, under the new guidelines, wouldn't be treated until their blood weight topped 150/90, instead of 140/90. In Sampson's study, the researchers evaluated how public high blood pressure was in more than 69000 men and women. Overall, 57 percent self-reported that they had dear blood pressure.

Effect Of Both Parents For The Child's Health

Effect Of Both Parents For The Child's Health.
Black men who were raised in single-parent households have higher blood influence than those who done in at least department of their childhood in a two-parent home, according to a new study Dec 2013. This is the first burn the midnight oil to link childhood family living arrangements with blood pressure in black men in the United States, who lean to have higher rates of high blood pressure than American men of other races. The findings suggest that programs to strengthen family stability during childhood might have a long-lasting effect on the jeopardize of high blood pressure in these men. In the study, which was funded by the US National Institutes of Health, researchers analyzed information on more than 500 black men in Washington, DC, who were taking area in a long-term Howard University family study.

The researchers adjusted for factors associated with blood pressure, such as age, exercise, smoking, ballast and medical history. After doing so, they found that men who lived in a two-parent household for one or more years of their puberty had a 4,4 mm Hg lower systolic blood constrain (the top number in a blood pressure reading) than those who spent their absolute childhood in a single-parent home.

One Third Of All Strokes Have Caused High Blood Pressure

One Third Of All Strokes Have Caused High Blood Pressure.
A philanthropic or oecumenic study has found that 10 risk factors account for 90 percent of all the chance of stroke, with high blood pressure playing the most potent role. Of that list, five imperil factors usually related to lifestyle - high blood pressure, smoking, abdominal obesity, chamber and physical activity - are responsible for a jammed 80 percent of all stroke risk, according to the researchers. The findings come the INTERSTROKE study, a standardized case-control contemplate of 3000 people who had had strokes and an equal number of healthy individuals with no report of stroke from 22 countries. It was published online June 18 in The Lancet.

The examine - slated to be presented Friday at the World Congress on Cardiology in Beijing - reports that the 10 factors significantly associated with occurrence risk are high blood pressure, smoking, carnal activity, waist-to-hip ratio (abdominal obesity), diet, blood lipid (fat) levels, diabetes, John Barleycorn intake, stress and depression, and heart disorders. Across the board, excited blood pressure was the most important factor, accounting for one-third of all stroke risk.

And "It's significant that most of the risk factors associated with stroke are modifiable," said Dr Martin J O'Donnell, an associate professor of medicine at McMaster University in Canada, who helped lead the study. "If they are controlled, it could have a substantial impact on the incidence of stroke".

Controlling blood pressure is important because it plays a notable role in both forms of stroke: ischemic, the most common form (caused by blockage of a sense blood vessel), and hemorrhagic or bleeding stroke, in which a blood vessel in the brain bursts. In contrast, levels of blood lipids such as cholesterol were eminent in the risk of ischemic stroke, but not hemorrhagic stroke.

So "The most consequential thing about hypertension is its controllability," O'Donnell said. "Blood urging is easily measured, and there are lots of treatments". Lifestyle measures to control blood pressure number reduction of salt intake and increasing physical activity. He added that the other risk factors - smoking, abdominal obesity, intake and physical activity - in the top five contributors to bit risk were modifiable as well.

Ethnicity And Vitamin D

Ethnicity And Vitamin D.
Black Americans who drive vitamin D supplements may significantly move their blood pressure, a new study suggests. "Compared with other races, blacks in the United States are more conceivable to have vitamin D deficiency and more likely to have high blood pressure," said supervise researcher Dr John Forman, an assistant professor of medicine at the renal compartmentation of Brigham and Women's Hospital in Boston. But among the black study participants, three months of supplemental vitamin D was associated with a slope in systolic blood lean on (the top number in a blood pressure reading) of up to 4 mm Hg, the researchers found.

And "If our findings are confirmed by other studies, then vitamin D supplementation may be a salutary means of dollop black individuals lower their blood pressure". Dr Michael Holick, a professor of medicine, physiology and biophysics at Boston University School of Medicine, said that vitamin D may diminish blood insistence by causing blood vessels to relax, allowing for more and easier blood flow.

In addition, because many vicious Americans are deficient in vitamin D, taking a supplement may benefit their health even more who was not convoluted with the study. "We are now beginning to believe that a lot of the health disparities between blacks and whites are due to vitamin D deficiency, including the jeopardize for type 2 diabetes, heart disease, cancers and even infectious disease".

Diet and sunlight are two unstudied sources of vitamin D in humans. However, having dark-colored graze cuts down on the amount of vitamin D the skin makes, according to the US National Institutes of Health. For the study, published online March 13 and in the April stamp climax of the journal Hypertension, Forman's team randomly assigned 250 black participants to one of three doses of vitamin D supplements or an quiescent placebo.

Diseases Of The Skin Depend On The Color

Diseases Of The Skin Depend On The Color.
Black women in the United States are much more credible to have considerable blood pressure than black men or ghostly women and men, according to a new study in Dec 2013. The researchers also found that blacks are twice as qualified as whites to have undiagnosed and untreated high blood pressure. "For many years, the zero in for high blood pressure was on middle-aged men who smoked.

Now we know better," said contemplate author Dr Uchechukwu Sampson, an assistant professor of medicine at Vanderbilt University Medical Center in Nashville, Tenn. For the study, which was published in the minutes Circulation: Cardiovascular Quality and Outcomes, researchers examined figures from 70000 people in 12 southeastern states known as the "stroke belt". This zone has higher rates of stroke than anywhere else in the United States.

High Systolic Blood Pressure And An Increased Risk For Heart Disease

High Systolic Blood Pressure And An Increased Risk For Heart Disease.
Young and middle-aged adults with cheerful systolic blood crushing - the uppermost number in the blood pressure reading - may have an increased risk for heart disease, a changed study suggests. "High blood pressure becomes increasingly common with age. However, it does manifest itself in younger adults, and we are seeing early onset more often recently as a result of the tubbiness epidemic," said study senior author Dr Donald Lloyd-Jones. He is a professor of epidemiology and cardiology at Northwestern University Feinberg School of Medicine in Chicago.

Earlier, insignificant studies have suggested that anomalous systolic high blood pressure might be harmless in younger adults, or the upshot of temporary nervousness at the doctor's office, Lloyd-Jones said. But this 30-year study suggests - but does not validate - that isolated systolic high blood pressure in young adulthood (average ripen 34) is a predictor of dying from heart problems 30 years down the road. "Doctors should not wink at isolated systolic high blood pressure in younger adults, since it unequivocally has implications for their future health," Lloyd-Jones said.

For the study, Lloyd-Jones and colleagues followed more than 27000 adults, ages 18 to 49, enrolled in the Chicago Heart Association Detection Project in Industry Study. Women with turned on systolic stress were found to have a 55 percent higher risk of on one's deathbed from heart disease than women with normal blood pressure. For men, the difference was 23 percent. The readings to on the watch for: systolic pressure of 140 mm Hg or more and diastolic twist (the bottom number) of less than 90 mm Hg.

Blood Pressure Rises As A Result Of Long-Term Air Pollution From Road Traffic

Blood Pressure Rises As A Result Of Long-Term Air Pollution From Road Traffic.
Long-term disclosing to the quality pollution particles caused by trade has been linked to an increase in blood pressure, US researchers say. In the unfledged report, researchers analyzed data from 939 participants in the Normative Aging Study, who were assessed every four years between 1995 and 2006.

A computer nonesuch was used to estimate each participant's risk to traffic air pollution particles during the entire study period and for the year preceding each four-year assessment. Increased conversancy to traffic pollution particles was associated with higher blood pressure, especially when the outlook occurred in the year preceding a four-year assessment (3,02 mm Hg improve in systolic blood pressure, 1,96 mm Hg increase in diastolic pressure, and 2,30 mm Hg broaden in mean arterial pressure), the study authors reported in a communication release from the American Heart Association.

This link between long-term exposure to traffic air dirtying particles and higher blood pressure readings may help explain the association between traffic fouling and heart attacks and cardiovascular deaths reported in previous studies, study author Joel Schwartz, of Harvard School of Public Health in Boston, and colleagues eminent in the news release. The findings were to be presented Thursday at the American Heart Association's Cardiovascular Disease Epidemiology and Prevention annual discussion in San Francisco.

Alzheimer's Disease Is Associated With A High Blood Pressure

Alzheimer's Disease Is Associated With A High Blood Pressure.
People agony from cardiovascular plague who have lower-than-normal blood pressure may face a higher jeopardize of brain atrophy - the death of brain cells or connections between brain cells, Dutch researchers news June 2013. Such brain atrophy can lead to Alzheimer's infection or dementia in these patients. In contrast, similar patients with high blood pressure can tame brain atrophy by lowering their blood pressure, the researchers added.

Blood pressure is measured using two readings. The choicest number, called systolic pressure, gauges the pressure of blood poignant through arteries. The bottom number, called diastolic pressure, measures the pressure in the arteries between heartbeats. Normal blood crushing for adults is less than 120/80, according to the US National Heart, Lung, and Blood Institute.

For the study, 70 to 90 was considered conformist diastolic blood pressure, while under 70 was considered low. "Our material might suggest that patients with cardiovascular disease represent a subgroup within the universal population in whom low diastolic blood pressure might be harmful," said researcher Dr Majon Muller, an epidemiologist and geriatrician at VU University Medical Center in Amsterdam.

On the other hand, lowering blood turn the heat on in populate with high blood pressure might slow brain atrophy, she said. "Our findings could mean that blood pressure lowering is beneficial in patients with higher blood coerce levels, but one should be cautious with further blood pressure lowering in patients who already have low diastolic blood pressure," Muller added.

In The USA Hypertensive Diseases Have Become Frequent

In The USA Hypertensive Diseases Have Become Frequent.
The distribution of Americans reporting they have violent blood pressure rose nearly 10 percent from 2005 to 2009, federal vigour officials said 2013. High blood pressure - or hypertension, a biggest risk factor for heart disease and stroke - affects nearly one-third of Americans, said Fleetwood Loustalot, a researcher at the National Center for Chronic Disease Prevention and Health Promotion, quarter of the US Centers for Disease Control and Prevention. About 26 percent of Americans said they had anticyclone blood require in 2005, and more than 28 percent reported exuberant blood pressure in 2009 - a nearly 10 percent increase.

And "Many factors donate to hypertension," Loustalot said, including obesity, eating too much salt, not exercising regularly, drinking too much John Barleycorn and smoking. "What we are really concerned about as well is that people who have high blood on are getting treated. Only about half of those with hypertension have it controlled. Uncontrolled hypertension can lead to negative form consequences like heart attacks and strokes".

Of the study participants who said they had high blood power in 2009, about 62 percent were using medication to control it. Loustalot said the multiply in the prevalence of high blood pressure is largely due to more awareness of the problem.

Cell Phones To Remotely Control Your Blood Pressure

Cell Phones To Remotely Control Your Blood Pressure.
Diabetics may soon chance that aid in controlling their blood pressurize is just a cell phone screen away. Researchers are now exploring the concealed of a new mobile phone monitoring method that automatically picks up patients' home blood pressure readings, which is then sent out wirelessly via broadcast signals from monitoring kit outfitted with Blue-tooth technology effects. The cell phones are pre-programmed to telephone the blood pressure readings and receive devote feedback (which appear instantly on the cell phone screen).

Good readings may instant a message of "Congratulations," while problematic results may trigger a communication advising the patients to make a check-up appointment with their doctor. The interactive procedure may also instruct patients to reserve more readings over a specified period of time to get a more reliable overall reading.

What's more, if any two-week or three-day patch exceeds a pre-set average reading threshold, the patient's attend would be automatically notified. In addition, doctors would be able to log online to suspension their patient's readings. Dr Alexander G Logan, from the University of Toronto, is slated to debate the theoretical monitoring system Wednesday at the American Heart Association annual meet in Chicago.

One expert said the technology can require a valuable service. "Telemonitoring provides intelligence regarding a patient's progress and condition between physician visits, and assists clinicians in identifying patients who have originally symptoms of a more sincere condition that, if left untreated, may require acute care, take pleasure in hospitalization," explained Dr Peter Rutherford, medical the man at Wenatchee Valley Medical Center in Wenatchee, Wash. "In the end," he said, "the patient's appointment in the program, coupled with the trunk manager's involvement in the patient's mindfulness and the physician's practice, is a vital piece of the disease operation puzzle".
