Laser Cataract Surgery More Accurate Than Manual

Laser Cataract Surgery More Accurate Than Manual.
Cataract surgery, already an extraordinarily justifiable and successful procedure, can be made more precise by combining a laser and three-dimensional imaging, a creative study suggests. Researchers found that a femtosecond laser, used for many years in LASIK surgery, can abridged into delicate eye tissue more cleanly and accurately than manual cataract surgery, which is performed more than 1,5 million times each year in the United States vigrx. In the going round procedure, which has a 98 percent name rate, surgeons use a micro-blade to cut a circle around the cornea before extracting the cataract with an ultrasound machine.

The laser scheme uses optical coherence technology to customize each patient's comprehension measurements before slicing through the lens capsule and cataract, though ultrasound is still used to remove the cataract itself. "It takes some technique and energy to break the lens with the ultrasound," explained edge researcher Daniel Palanker, an associate professor of ophthalmology at Stanford University vigora lido spray use. "The laser helps to step on it this up and make it safer".

After practicing the laser procedure on pig eyes and donated woman eyes, Palanker and his colleagues did further experiments to confirm that the high-powered, rapid-pulse laser would not cause retinal damage. Actual surgeries later performed on 50 patients between the ages of 55 and 80 showed that the laser engraving circles in lens capsules 12 times more truthful than those achieved by the stock method. No adverse effects were reported.

The study, reported in the Nov 17, 2010 debouchment of Science Translational Medicine, was funded by OpticaMedica Corp of Santa Clara, Calif, in which Palanker has an disinterest stake. The results are being reviewed by the US Food and Drug Administration, while the laser technology, which is being developed by several own companies, is expected to be released worldwide in 2011.

Nutritionists Recommend Some Rules

Nutritionists Recommend Some Rules.
In the furor of holiday celebrations and gatherings, it's acquiescent to forget the basics of food safety, so one expert offers some simple reminders. "Food shelter tips are always important, and especially during the holidays when cooking for a crowd," Dana Angelo White, a nutritionist and Quinnipiac University's clinical helper professor of athletic training and sports medicine, said in a university info release edhelp.top. "Proper hand washing is a must!" Simply washing your hands is an portentous way to stop the spread of germs, Angelo White advised.

She eminent that providing guests with festive and scented soaps will encourage them to keep their hands clean in the kitchen. Angelo White provided other tips to daily those preparing meals ensure holiday edibles safety, including vigrx lelong. don't cross contaminate. Using separate cutting boards for sensitive meats and seafood is key to preventing the spread of harmful bacteria.

Raw meats, poultry and seafood should also be stored on the bottom shelf in the refrigerator so that drippings from these products do not vitiate other foods. It's also important to circumvent rinsing raw meat in the sink. Contrary to popular belief, research suggests, this wont can spread bacteria rather than get rid of it. Consider time and temperature.

Doctors Recommend A New Type Of Flu Vaccine

Doctors Recommend A New Type Of Flu Vaccine.
A vaccine that protects children against four strains of flu may be more operative than the usual three-strain vaccine, a budding scrutinize suggests. The four-strain (or so-called "quadrivalent") vaccine is available as a nasal spindrift or an injection for the first time this flu season. The injected version, however, may be in transient supply, according to the US Centers for Disease Control and Prevention skin care. The study of about 200 children did not correlate the four-strain vaccine to the traditional three-strain vaccine.

Rather, it looked at how kids responded either to the four-strain vaccine or a hepatitis A vaccine, and then compared retort rates for the four-strain flu vaccine to reply rates for the three-strain vaccine from last year's flu season make your own skin bleaching cream. "This is the before large, randomized, controlled trial to demonstrate the efficacy of a quadrivalent flu vaccine against influenza in children," said work co-author Dr Ghassan Dbaibo.

"The results showed that, by preventing sensible to severe influenza, vaccination achieved reductions of 61 percent to 77 percent in doctors' visits, hospitalizations, absences from seminary and parental absences from work," said Dbaibo, at the segment of pediatrics and adolescent medicine at the American University of Beirut Medical Center, in Lebanon. The results endorse the effectiveness of the vaccine against influenza, and particularly against moderate to painstaking influenza.

"They also showed an 80 percent reduction in lower respiratory tract infections, which is the most common bad outcome of influenza. Therefore, vaccination of children in this age group can help to reduce the significant millstone placed on parents, doctors and hospitals every flu season. The report was published online Dec 11, 2013 in the New England Journal of Medicine.

The ruminate on was funded by GlaxoSmithKline, maker of the four-strain vaccine worn in the study. Dr Lisa Grohskopf, a medical cop in CDC's influenza division, said there are several flu vaccine options for children. For children age-old 2 and up, a nasal spray is an option, and for children under 2, the usual injection is available. "The nasal vaporizer vaccine is a quadrivalent vaccine, which has four different flu viruses in it.

Obese People Are More Prone To Heart Disease Than People With Normal Weight

Obese People Are More Prone To Heart Disease Than People With Normal Weight.
The impression that some tribe can be overweight or obese and still tarry healthy is a myth, according to a new Canadian study. Even without high blood pressure, diabetes or other metabolic issues, overweight and plump people have higher rates of death, heart seize and stroke after 10 years compared with their thinner counterparts, the researchers found anti ne mujko rat ko waigra khilakar sexy story. "These matter suggest that increased body weight is not a benign condition, even in the absence of metabolic abnormalities, and argue against the concept of nourishing obesity or benign obesity," said researcher Dr Ravi Retnakaran, an associate professor of medicament at the University of Toronto.

The terms healthy obesity and benign obesity have been used to portray people who are obese but don't have the abnormalities that typically accompany obesity, such as high blood pressure, euphoric blood sugar and high cholesterol. "We found that metabolically healthy obese individuals are truthfully at increased risk for death and cardiovascular events over the long term as compared with metabolically bracing normal-weight individuals" garciniacambogia scriptovore.com. It's possible that obese people who appear metabolically healthy have quiet levels of some risk factors that worsen over time, the researchers suggest in the report, published online Dec 3, 2013 in the Annals of Internal Medicine.

Dr David Katz, skipper of the Yale University Prevention Research Center, welcomed the report. "Given the modern attention to the 'obesity paradox' in the skilful literature and pop culture alike, this is a very timely and important paper". The rotundity paradox holds that certain people benefit from chronic obesity. Some obese plebeians appear healthy because not all weight gain is harmful.

New way to fight mosquitoes

New way to fight mosquitoes.
Researchers have versed more about how mosquitoes determine skin odor, and they say their findings could lead to better repellants and traps. Mosquitoes are attracted to our pelt odor and to the carbon dioxide we exhale. Previous research found that mosquitoes have special neurons that delegate them to detect carbon dioxide how big is a b cup breast size. Until now, however, scientists had not pinpointed the neurons that mosquitoes use to dig up skin odor.

The new study found that the neurons used to detect carbon dioxide are also Euphemistic pre-owned to identify skin odor. This means it should be easier to find ways to block mosquitoes' wit to zero in on people, according to the study's authors surgery. The findings appeared in the Dec 5, 2013 progeny of the journal Cell.

An Involuntary Tics Can Be Suppressed Through Self-Hypnosis

An Involuntary Tics Can Be Suppressed Through Self-Hypnosis.
Children and prepubescent adults with Tourette syndrome can dividend control over their involuntary tics through self-hypnosis, a selfish new study suggests. But a specialist in the condition said the research is too preliminary to specify whether the strategy actually works free neosize xl sample. In the study, reported in the July/August issue of the Journal of Developmental & Behavioral Pediatrics, researchers old a video to teach 33 people venerable 6 to 19 how to relax through self-hypnosis.

The participants all had the tics caused by Tourette syndrome. "Once the self-possessed is in his or her highly focused 'special place,' work is then done on controlling the tic herbalms.com. We pray the patient to imagine the feeling right before that tic occurs and to put up a stop sign in front of it, or to conjecture a tic switch that can be turned on and off like a light switch," study co-author Dr Jeffrey Lazarus, time past of the Case Western Reserve University School of Medicine and now in confidential practice, said in a news release from the journal's publisher.

Air Travel May Increase The Risk Of Cardiac Arrhythmia And Heartbeat Irregularities

Air Travel May Increase The Risk Of Cardiac Arrhythmia And Heartbeat Irregularities.
Air roam could relieve the risk for experiencing heartbeat irregularities in the midst older individuals with a history of heart disease, a new study suggests edhelp.top. The judgement stems from an assessment of a small group of people - some of whom had a history of heart disability - who were observed in an environment that simulated flight conditions.

She said"People never think about the fact that getting on an airplane is basically similarly to going from sea level to climbing a mountain of 8000 feet," said exploration author Eileen McNeely, an instructor in the department of environmental health at the Harvard School of Public Health in Boston. "But that can be very stressful on the heart flacid and erect penis pictures. Particularly for those who are older and have underlying cardiac disease".

McNeely and her band are slated to mete out their findings Thursday at the American Heart Association's Cardiovascular Disease Epidemiology and Prevention annual meeting in San Francisco. The authors respected that the number one cause for in-flight medical emergencies is fainting, and that feeling faint and/or dizzy has heretofore been associated with high altitude exposure and heartbeat irregularity, even among elite athletes and otherwise flourishing individuals.

To assess how routine commercial air travel might affect cardiac health, McNeely and her colleagues gathered a corps of 40 men and women and placed them in a hypobaric chamber that simulated the atmospheric locale that a passenger would typically experience while flying at an altitude of 7000 feet. The mediocre age of the participants was 64, and one-third had been previously diagnosed with heart disease.

Over the run of two days, all of the participants were exposed to two five-hour sessions in the hypobaric chamber: one reflecting simulated airliner conditions and the other reflecting the atmospheric conditions experienced while at sea level. Throughout the experiment, the experiment with team monitored both respiratory and heart rhythms - in the latter exemplification to specifically see whether flight conditions would prompt extra heartbeats to occur in either chamber of the heart.

Excess Weight Is Not The Verdict

Excess Weight Is Not The Verdict.
For the basic time, researchers have shown that implanting electrodes in the brain's "feeding center" can be safely done - in a c to grow a new treatment option for severely obese people who fail to shed pounds even after weight-loss surgery. In a prior study with three patients, researchers in June 2013 found that they could safely use the therapy, known as deeply brain stimulation (DBS). Over almost three years, none of the patients had any grave side effects, and two even lost some weight - but it was temporary increase. "The original thing we needed to do was to see if this is safe," said lead researcher Dr Donald Whiting, depravity chairman of neurosurgery at Allegheny General Hospital in Pittsburgh.

And "We're at the point now where it looks derive it is". The study, reported in the Journal of Neurosurgery and at a meeting this week of the International Neuromodulation Society in Berlin, Germany, was not meant to check effectiveness howporstarsgrowit.com. So the big remaining doubt is, can deep brain stimulation actually promote lasting weight loss?

"Nobody should get the estimation that this has been shown to be effective. This is not something you can go ask your doctor about". Right now, deep intelligence stimulation is sometimes used for tough-to-treat cases of Parkinson's disease, a movement disorder that causes tremors, firm muscles, and balance and coordination problems. A surgeon implants electrodes into established movement-related areas of the brain, then attaches those electrodes to a neurostimulator placed under the skin near the collarbone.

The neurostimulator continually sends infinitesimal electrical pulses to the brain, which in turn interferes with the irregular activity that causes tremors and other symptoms. What does that have to do with obesity? In theory deep genius stimulation might be able to "override" brain signaling involved in eating, metabolism or feelings of fullness.

Research in animals has shown that electrical stimulation of a noteworthy area of the brain - the lateral hypothalamic area - can barbel weight loss even if calorie intake stays the same. The new mull over marks the first time that deep brain stimulation has been tried in that brain region. And it's an grave first step to show that not only could these three severely obese people get through the surgery, but they also seemed to have no straightforward effects from the brain stimulation, said Dr Casey Halpern, a neurosurgeon at the University of Pennsylvania who was not snarled in the research.

The Efficacy Of Antiseptic Soap

The Efficacy Of Antiseptic Soap.
The US Food and Drug Administration said Monday that it wants makers of antibacterial relief soaps and body washes to sustain their products are securely for long-term daily use and more effective than regular soaps in preventing illness and the stretch of certain infections. Unless companies can do that, they would have to reformulate or re-label these products if they want to keep them on the market, the intervention said in Dec 2013 top. "Millions of Americans use antibacterial soaps and body washes," Dr Sandra Kweder, proxy director of the FDA's Office of New Drugs, Center for Drug Evaluation and Research, said during a matinal press briefing.

And "They are used every day at home, at work, at schools and in other clear-cut settings where the risk of bacterial infection is relatively low. We at the FDA suppose there should be clearly demonstrated benefits from using antibacterial soaps to balance any potential risk" bestvito.eu. Kweder said the FDA has not been provided with observations that shows these products are "any more effective at preventing hoi polloi from getting sick than washing with plain soap and water".

The Problem Of The Use Of Unproven Dietary Supplements

The Problem Of The Use Of Unproven Dietary Supplements.
US salubrity authorities Wednesday intensified demand on makers of dietary supplements, threat individuals or companies marketing "tainted" products that they could face criminal prosecution, among other consequences. The gesture comes after several reports of injury and even death from the use of illegal supplements that are deceptively labeled or carry undeclared ingredients female. These include those laced with the same active ingredients as drugs already approved by the US Food and Drug Administration, analogs (close copies) of those drugs or novelette spurious steroids that don't qualify as dietary ingredients.

And "Some contain prescription drugs or analogs never tested in humans and the results can be tragic," said Dr Joshua Sharfstein, director spokesperson commissioner at the FDA, at a Wednesday news conference vigrxbox.com. "We have received reports of serious adverse events and injuries associated with consumer use of these tainted products, including stroke, liver and kidney damage, pulmonary flop and death".

Since 2007 FDA has issued alerts on 300 tainted products. "FDA is expertise prominence to an important public health problem. Serious injuries have resulted from products masquerading as dietary supplements. They're mainly poorly labeled so consumers don't recognize what they're buying".

Most of the illegal products are marketed in three categories: to further weight loss, to enhance sexual prowess and as body-building products, the agency noted. The weight-loss products identified with problems comprehend Slimming Beauty, Solo Slim and Slim-30, which restrict sibutramine (or analogs), the active ingredient in the FDA-approved drug Merida, recently shrinking from pharmacy shelves due to a heightened risk of heart attack and stroke.

The body-building products comprise Tren Xtreme, ArimaDex and Clomed, which contain anabolic steroids or aromatase inhibitors, a order of cancer-fighting drugs that interfere with estrogen production. Consumers should also be aware of "products that stipulate warnings about testing positive in performance drug tests".
