Sedentary jobs, helping the obesity epidemic Drive

 as Americans sit - literally - in more sedentary jobs, they're packing on the pounds, and it is this inertia which is a major contributor to the obesity epidemic, new research suggests.

Look at the computer for hours rather than hoeing the fields means that us are 120 to 140 burning less calories per day than they were 50 years ago.

Therefore promote any type of physical activity should be more important in this war the weight, according to a study in the Edition online may 25 in the journal PLoS ONE.

"It is calories in and calories out, and we're more calories in that we take, said Dr. Robert Graham, a primary care physician at Lenox Hill Hospital in New York."

Led an inclination towards calories in two-thirds of American adults are now overweight or obese.

Although dietary habits and exercise have been studied to the obesity epidemic, these researchers, from Biomedical Research Centre Pennington in Baton Rouge, Louisiana), stated that a large part of the responsibility for the extra weight was put on the caloric intake.

This is because the amount of recreational physical activity has not really changed over the years.

But what physical requirements of work, where so many people spend most of their days?

These researchers cross-referenced U.S. Bureau of Labor Statistics on the prevalence of different jobs with a large national database which includes information on body weight.

Fifty years ago, about half of private-industry jobs involved United States a kind of physical activity, things such as agriculture, mining, construction and manufacturing. Today, this number is less than 20%, with the dominance of jobs in the retail, education and business sale.

The authors estimate that less than 100 calories out each day would lead to weight gain in what the U.S. population has seen since the 1960s.

However, if Americans were following federal guidelines for physical activity (150 minutes per week of moderate intensity exercise or 75 minutes of more vigorous activity), these additional calories would have been levelled.

Only one in four Americans made the recommended exercise level, the authors reported.

"We need to encourage physical activity most, particularly given that us sit more during the day that we has 100 years," says Keri Gans, a spokesman for the American Dietetic Association and the author of the diet of Small Change.

"The requirements of daily life are in competition with exercise," said Graham. "We have just in time for it to do."

Gans recommends that people move to work even if they have what amounts to an employment office. That could take the stairs when you can walk on the counter of a co-travailleur when you can and taking a walk at lunch. And if your company happens to have a gym or exercise program, by all means, you will participate.

Lists of the side effects of the Prescription Meds continued growth: study (HealthDay)

(Thursday, May 26, HealthDay News) - lists of the side effects of prescription drugs on drug labels, packaging and advertisements have proliferated to an average of 70 by drug, a new study reports.

Warnings on side effects have been designed to inform physicians and consumers of the potential hazards, but this expansion may have had more to do with concerns over disputes rather than real health problemssay the authors of the study, which argue that the information could be presented much more effectively.

"Having a high number of side effects on the label of a drug should not suggest that the drug is dangerous." In fact, much of this labelling has less to do with toxicity real to protect manufacturers from possible prosecution, "principal investigator study author Dr. Jon Duke, Regenstrief Institute and Assistant Professor of medicine at the Indiana University School of Medicine"said in a press release from the University.

An analysis of more than 5,600 tags drugs and side effects more than 500 000 concluded that prescription drug labels include an average of 70 different adverse potentials - a number which jumps to 100 of the side effects of some commonly prescribed drugs.

Some drugs in the upper range listed even 525 reactions.

Duke pointed out that the large number of listed side effects could overburden physicians to browse this information to make informed decisions about medications for their patients.

For the study, published in issue 23 May of the Archives of Internal Medicine, researchers have compiled a list of prescriptions drug types who were most likely to have a high number of marked side-effects. These drugs include antidepressants, antiviral drugs and new treatments for restless legs syndrome and Parkinson's disease.

Despite the enormous amount of information found in the labelling of current drugs, Duke argued that data could be useful if presented properly.

"With the current technology, drug labels could be processed long static documents from dynamic resources capable of providing custom patient information." "These labels could take into account medical conditions of the individual patient and to highlight the side effects that may be particularly dangerous," he said.

"We cannot stop the growing wave of drug information, but we can do a better job of presenting effectively to health care providers," Duke found.

New drug extends survival for men with advanced prostate Cancer

for men with advanced hormone-resistant prostate cancer who have failed also chemotherapy, the new drug Zytiga (abiraterone acetate) with the steroid prednisone appears to boost survival, researchers report.

Based on current clinical trial data, Zytiga has been approved by the Food and Drug Administration in April. It works by inhibiting the production of the hormone male testosterone, that promotes the growth of cancer cells. In this regard, the drug mimics the hormone therapy.

Zytiga "extends overall survival in this patient population which had very limited treatment options after chemotherapy" researcher principal Dr. Fred Saad, Chief of Urology at the hospital Notre-Dame de Montréal, said at a press conference of Monday morning.

The men in the combination of drugs had a mean survival of 14.8 months, compared to 10.9 months for men taking placebo.

"Abiraterone represents an option of valuable treatment for patients with metastatic castration [hormone] - resistant of the prostate which had been previously treated with chemotherapy, very easy to manage, treatment-related toxicity in" Saad said.

The study was published in issue 26 May of the New England Journal of Medicine. The findings were also presented may 16 at the annual meeting of the American Urological Association, in Washington, D.C.

The study focused on the 1,195 men prostate cancer that has not responded to hormone therapy and that he had no prior chemotherapy. Researchers, hospitals of 147 in 13 countries, randomly men to take Zytiga more prednisone or placebo.

The combination of drugs was well tolerated and has given rise within fatigue, back pain and spinal compression taking men, compared to placebo, Saad said.

The most common side effects in people taking prednisone and Zytiga were lower white blood cell, a retention, rates of low potassium, abnormal liver function tests, blood pressure and heart problems, the researchers noted.

A one month supply 120 pills of Zytiga costs $ 5,000, said Kelly McLaughlin, a spokesman of Centocor Ortho Biotech Inc., manufacturer of the drug and a promoter of the study.

"This study tells us that there is a form of hormonal treatment, abiraterone, who works among people who had chemotherapy and hormonal treatment standard," said expert Dr. Anthony D'Amico of prostate cancer, head of the apparatus Genitourinary Oncology at Brigham and women's Hospital in Boston.

"It will provide people with the disease late with an opportunity for a prolonged survival that they had not before." "I can't say that it is a term of home because it is only a few months improved,", he added.

Aggressive prostate cancer may be able to make its own testosterone, cancer cells need to grow. "Zytiga blocks that", said D'Amico.

"This drug offers longer life and better quality of life in men with very advanced prostate cancer," said D'Amico. "There are studies now to see if this medication will improve the rate of healing in men with advanced, but not [metastatic cancer that has spread to other organs], prostate cancer,", he added.

Skin Cancer foes declared may 27 "Don't fry day" (HealthDay)

on Friday, the beginning of the end of week Memorial Day, is also "Don ' T fry day," once for skin safety experts remind Americans about the dangers of overexposure to the Sun.

Melanoma, the potentially deadly form of skin cancer is the most common cancer in young adults in the late twenties, according to the U.S. Environmental Protection Agency (EPA) and the National Council for the prevention of Skin Cancerwho have joined forces to offer advice to save lives on the caution in the Sun. The main cause of skin cancer: overexposure to harmful ultraviolet (UV).

"Many people still don't realize that exposure to the Sun without protection can lead to cancer of the skin and other health problems," said Gina McCarthy, agency Administrator assistant for the EPA Office of Air and radiation, in a press release. "Simple steps, such as using a sunscreen, wear sunglasses or a hat, can protect us and our families, while still enjoying the outdoors."

Skin cancer, the most common type of cancer in the United States, affects more than 2 million U.S. dollars - every year more breast cancer, prostate, lung and colon combined, said the EPA. Every hour, an American dies of cancer of the skin, the Agency noted.

Although the UV rays are dangerous year round, the risks are greatest in the summer months when people spend more time outdoors, McCarthy said.

To limit exposure to harmful UV rays, expert proposes to you:

Cover you. One of the most effective ways to reduce the exposure to the harmful rays of the Sun is to wear a shirt, hat and sunglasses and Sunscreen SPF 15 +. Find a shady place. It is best to stay out of direct light from the Sun during peak hours, from 10 h to 16 h being aware of the UV index. Get involved in outdoor activities, check the UV index to identify the time more risky for overexposure to the Sun.

Childhood treatments related to gastrointestinal problems

 children who are treated successfully for cancer are more at risk of developing severe mild gastrointestinal problems on the road, a new study concludes.

Researchers at the University of California, San Francisco analyzed the self-reported gastrointestinal (GI) problems of 14,358 patients surviving at least five years after the treatment of cancers such as lymphoma, leukemia, tumors of the brain or bone tumours.

More than 40 per cent have experienced some type of problem of IM - including ulcers, the disease of the esophagus, indigestion, polyps, chronic diarrhea, colitis, gallstones and jaundice - in two decades of their treatment, researchers have discovered.

In addition, people with cancer at a later age and who had to undergo a more rigorous treatment (chemotherapy, radiotherapy, surgery) were more likely to experience problems IM long term, according to the study of the may issue of Gastroenterology.

About one in 500 young adults in the United States is a survivor of childhood cancer, the study authors noted in a press release UCSF.

"While doctors continue to learn more about pediatric cancer and its treatment long term consequences, it is essential that we provide care of comprehensive follow-up that adequately addresses the complications can meet the cancer survivors.""," study lead author Dr. Robert Goldsby, specialist of pediatric cancer hospital for children of Benioff UCSF and Director of the UCSF Cancer of childhood survivors program, said in the press release.

"These are serious issues that can have a real impact on the quality of life of the person," added Goldsby.

Combo of Paxil, Pravachol may raise the sugar in the blood

 taken in combination, two drugs commonly prescribed antidepressant Paxil and the cholesterol-lowering Pravachol drugs seem increases significantly the blood glucose, a new study concludes.

The increase is more apparent - and for - in the diabetic whose blood sugar is already too high, the researchers noted.

"This interaction may affect up to 1 million Americans who would be on these two drugs and who get a bump in their blood glucose may be unnecessary," said researcher principal Dr. Russ Altman, Professor of biological, genetic engineering and medicine at Stanford University.

It is possible that the blood sugar spike triggered a diagnosis of diabetes type 2 patients, Altman said, "and we could avoid this diagnosis if they had not been on these drugs", he said. "This is speculative, but it is possible."

No single drug raises sugar in the blood and the researchers said they cannot yet explain the effect of the combination. Also, combinations of other antidepressants and cholesterol not stimulate glucose levels. "This is not what we would call a"class"effect", Altman explained.

Paxil (paroxetine) is in a class of drugs known as inhibitors of the reuptake of serotonin (SSRIS) and Pravachol (Pravastatin) belongs to a group of drugs called statins. "We looked at all the other pairs of SSRIS and Statins and there were a couple who has shown a small bump in glucose, but there is nothing to do with the humpback seen Paxil and Pravachol," Altman said.

For the study, published online may 25 in clinical and therapeutic Pharmacology, researchers have used a technique called data mining, analysis of large databases in the hope of finding information which, although not immediately obviousis gleaned by combining the data in a new way.

In this case, team Altman used the data from the U.S. Food and Drug Administration Adverse Event Reporting System, more data from the universities of Harvard, Stanford and Vanderbilt to identify the associations would not apparent doctors dealing with individual patients.

Using this method, researchers have identified 135 non-diabetic patients taking both drugs whose blood sugar increased of 19 milligrams per deciliter after the start of treatment. They have also identified 104 diabetic whose blood sugar increased an average of 48 mg/dl while taking the two drugs.

With levels of sugar in the blood of 126 mg/dl or two tests are considered diabetic. Levels of 100 mg/dl to 125 mg/dl are considered prédiabétiques.

By extrapolating these results to the whole of the population of the United States, the Altman team believes that of 33 million people taking Paxil or Pravachol, 500 000 to 1 million hold together.

To verify whether their conclusions were simply associations which could be explained by other factors, researchers have experimented with drugs in mice.

The mice were exposed to two drugs after receiving a diet rich in fat, high calorie to pre-diabetic. No single drug has increased sugar in the blood, together they have increased sugar in the blood of about 128 mg/dl to 193 mg/dl, the researchers found.

"It was just like humans in our data base, said Altman." So, this seems to be a real biological effect. "This could give us an overview of the mechanisms of diabetes."

Altman warns that people taking this drug combination should not respond.

He has said "people on an antidepressant should not mess with because depression is a very serious illness". It would be reasonable to see a doctor and see if your blood glucose have been difficult to control, he said. He said "if it was, then I think the thing to change would be the Statin,".

Dr. Ronald b. Goldberg, Professor of medicine at the Institute for research of diabetes at the University of Miami Miller School of Medicine, said that it was "" an interesting conclusion and could be clinically important. ""

"People with diabetes have an increased risk of depression." they are all recommended to be on Statins, "said Goldberg. "Then, it can worsen glycemic control in diabetic people."

But Goldberg thinks that it is too early to change clinical practice based on this study only. "This must be confirmed in a clinical trial," he said.

Commitment capacity can begin early childhood (HealthDay)

the ability of men and women of power staying and a high level of commitment in their relationships back to their childhood and adolescence, a new study concludes.

78 Persons aged 20 or 21 and their heterosexual partners on their level of commitment to their relationship, the researchers asked.

Researchers have already given on participants when they were between the ages of 16 and 2, including how loving and attentive, their mothers were while they were for toddlers, and how they dealt with a conflict with a friend as teenagers.

The researchers found that toddlers who were well treated by their mother and were best resolve conflicts adolescents tend to be committed in adult relationships.

People who stick, however, may be successful alone step taking a relationship together, researchers will be added.

Those who had similar commitment feelings - if these feelings were strong or weak - are more likely to stay together in the long term than the two persons whose level of commitment does not fit.

The study is published in the June issue of psychological Science.

In the study, couples were invited to tell how they tried to resolve a major conflict in their relationship and what they agreed for the most part. The researchers assessed their levels of hostility and feelings of despair on the relationship, and how couples tried to appease the other.

The study found that couples with different levels of commitment were the antagonists. When combined with a weak link, a strong link is losers and become the underdog with less influence. On the reverse, two weak links in a relationship can tolerate everything also low expectations.

The researchers concluded learn them that study findings open a window on the human understanding of how people to love. "Like children, you learn how to manage your own needs and those of the people you care about," said Mr. Minda writing of St. Olaf College in a press release from the Association for psychological Science. "You will learn: can I come forward with a problem." What can I expect from the other person? "And how can I do this so that everyone wins"?

Cancer Patients benefit from full access to medical records

Cancer Patients who are given full access to their medical record feel a greater sense of satisfaction about their treatment, a new study finds.

French researchers also concluded that provide complete and accurate medical information built of trust between the patient and the physician.

Published online on May 23 in the journal Cancer, the study analyzed 295 patients recently diagnosed cancer Lymphoma, breast or colon cancer. All were treated by chemotherapy.

Patients received either "on request information", or organized medical file (OMR) - a Briefcase complete detailed information on their condition and treatment. These information included reports on all, surgery, radiology and pathology results, with the nurse stories and observations of treatment. With SEO, they received guides on medical terms and understand the material, as well as to help medical personnel to decipher the various documents.

Eighty Eighteen per cent of patients who offered an OMR has chosen to take.

Patients who have received on-demand information has been provided only information and medical records if they asked for them or their doctor offered.

Similar anxiety and quality of life scores levels have been reported in the two groups.

But patients with OMR were 1.68 times more likely to be satisfied with their medical information and were 1.86 times more likely to feel fully informed, the authors of the study noted.

And 70.4% of the patients who received an OMR has said that they would once more to receive, with 74.8% saying: they not regret their choice. In addition, the majority of these patients has been reported that SEO was not the source of any anxiety.

"Information is crucial to make decisions of treatment options, and for the patient and his family, to cope with the disease and its consequences," study author Dr. Gwenaelle Gravis, the Paoli-Calmettes Institute in Marseillesaid in a press release of the editor of the journal. "Full access to his medical file with the possibility to consult only if you want increased patient confidence in the physician and the medical team."

More Docs to primary care in a community equals healthier seniors

primary care physicians more a community, especially those that are actually practicing primary care, that community healthier seniors are, suggests a new study by Dartmouth.

These communities see less avoidable hospitalizations and a slightly lower rate of mortality among seniors, the researchers found.

"This reinforces something resisted the American family physicians [AAFP] Academy for a long time: that a competent doctor can maintain results," said AAFP President Dr. Roland Goertz, who had observed that some 100 different studies is today the identical or similar conclusions. "."

This study and others come in the context of a pool of shrinkage of primary care physicians. A study last month revealed that the percentage of medical students who want to go into medicine for primary health care has fallen sharply during the past two decades, from 57% in 1990 to 33 for one hundred and twenty years later.

In 1990, 57 per cent wanted to go into medicine primary care against 33 per cent in 2007, this previous study. Those who choose to practice general internal medicine in 2007 fell by 9% to 2%. And in 2008, the medical students only 264 U.S. chose residency training in internal medicine, primary health care, compared to 575 in 1999.

But having more physicians primary care is a cornerstone of most of the strategies to improve the quality of health care and reduce costs to the United States, the authors of the current study report. Their finding appears in the issue of the Journal of the American Medical Association on May 25.

These authors have watched doctor claims for Medicare recipients about 5 million of 65 years and older from files of the American Medical Association. Claims coding for medical specialty and the type of care provided, said the author of the study Chiang-Hua Chang, an instructor of research with the Center for Health Policy Research at the Dartmouth Institute for health and clinical practice in the LibanN.H policy.

Elderly people in the regions where the greatest number of primary care physicians were less avoidable hospitalizations and fewer deaths.

The differences were certainly small. For example, the recruits of Medicare living in areas where the most per capita primary care physicians had a lower rate of 6% of preventable hospitalizations.

But the authors also found that it is not enough just to receive training in primary health care. To be practical primary care as well, something that future studies should take into account, the doctors said Chang.

Many trained primary care physicians appear to be exercising in specialties like emergency medicine, or only inpatient care, she added.

"I think that this raises several important issues," said Dr. Lawrence c. Kleinman, Associate Professor of evidence and health policy at the Mount Sinai School of Medicine in New York. "We must ensure that there is adequate distribution of these physicians and primary care physicians."

"Right now, we tend to be paid when physicians of things, but we tend to value when doctors prevent things, which means manpower moves from primary health care for specialized care,", he added.

The shortage will leave?

"Not in the way in which we currently organize and fund care", said Kleinman. "Medical students react to their value and their market forces and currently the amount of the debt and the repayment of variances are trumping the values of the people and other preferences."

Regular Brisk walking can protect patients with Cancer of the Prostate

Prostate cancer Patients who take great walks on a regular basis succeeds better than those who think the contrary, a new study suggests.

They not only reduce their risk of disease progression, they lower their chances of dying of the disease, researchers reported.

The conclusion is based on previous research in the same group of scientists who had indicated that "vigorous physical activity" reduces the risk of dying from prostate cancer.

"Men who participate in walking fast, defined as three miles per hour or faster, after clinically localized prostate cancer diagnosis had a reduction of the risk of progression of prostate cancer than men who walked to an easy pace less than two miles per hour"study author Erin said"" L. Richman, research associate in the Department of epidemiology and biostatistics at the University of California, San Francisco.

"Men who engaged in three hours per week or more brisk walking has had the greatest advantage", Richman added, "with a lower risk of 57% of the progression of the disease compared to men having come less than three hours per week at an easy pace." These results were independent clinical prognostic factors, dietary factors and factors of life such as obesity and smoking. ?

Report of the Richman appears in number 1 June of Cancer Research.

The authors of the study noted that about 2.2 million men are now struggling with a diagnosis of prostate cancer in the United States, and the disease is the second leading cause of cancer death in American men. In 2010, approximately 217,000 new cases were diagnosed.

To explore how lifestyle can influence the progression of the disease after a diagnosis, the study team focused on 1,455 patients with prostate cancer who were enrolled in one of the 40 Clinical Urology in 2004 and 2005.

At the time where the study launched, all men had localized cancer, which means that their disease had not yet spread beyond the prostate.

All the men completed a survey to assess their physical activity routines. Richman notes that most of the men had initially suffered "cure," including the radical treatment of prostactectomy or radiation.

The researchers found that walking represents approximately half of all physical activity exercised by patients, and that those that have been observed walking in so-called "deep" way tended to be younger and more appropriate than those who walked more slowly. Brisk walkers were also less likely to smoke.

By stacking patterns of exercise against signs of telltale of progression of the disease (such as the PSA levels, the spread of the disease or death), the research team found that patients who walked quickly for a minimum of three hours per week had a rate of progression of the disease (57 per cent below) significantly lesser than those who walked at an easy pace for less than three hours per week.

In fact, the pace of the March appeared to be more important than the amount of time spent walking. Walk at an easy pace conferred no advantage of protection against the progression of prostate cancer.

The team of the informed Richman that additional research is needed to confirm the results. She also suggested that other types of exercise may also be useful.

Mr. Lionel l. Banez, Assistant Professor in the division of Urologic Surgery, in the Department of surgery at Duke University Medical Center has agreed that further research might find that other forms of exercise provide similar protection.

"It's very reasonable to extrapolate these findings to include other forms of physical activity", he noted. "Our own previous study show that moderate exercise which included various forms of physical activity, has been associated with less aggressive prostate cancer risk in veterans."

Simply eating less fat may reduce the risk of diabetes

weight loss cannot be held to reduce the risk of a person for diabetes, a new study argues.

Rather, the study concluded, small dietary changes can make a big difference of risk, even without weight loss and for Blacks particularly.

For the study, published online may 18 in the American Journal of Clinical Nutrition, researchers have developed 69 obese people at risk for diabetes diet for eight weeks with only small reductions for their intake of carbohydrates to fat. Low-fat group consume a diet composed of 27% of fatty carbohydrates and 55%. Group feeding low carbohydrate was 39 per cent fat and 43% of carbohydrates.

"Eight weeks, the Group on the diet low fat had significantly higher insulin secretion and glucose tolerance better and tend to be higher insulin sensitivity," lead author of the study, Barbara Gowera Professor of nutritional sciences at the University of Alabama at Birmingham, said in a press release from the University. The findings have been described as more strong among black participants.

"These improvements indicate a decrease in the risk for diabetes," said Gower.

Surprisingly, she added, participants in the study were at low risk for the disease regardless of whether if they have lost any weight.

"People find it hard to lose weight," said Gower. "" "". What is important about our study is that the results suggest that attention to the quality of the diet, not the quantity, can make a difference in the risk of diabetes type 2. ?

Limiting the daily fat intake to about 27% of the diet of the person can reduce the risk of diabetes in the long term, a study found.

Researchers noted that the necessary dietary changes are minimal and therefore easy to manage.

"Diets used in this study were actually quite moderate," Laura Lee Gorée, a dietitian at the University and a co-author of the study, said in the press release. "People at risk for diabetes could easily adopt the diet low fat, we have used.".

Too many children getting antibiotics for asthma

while the guidelines recommend antibiotics for asthma, almost a million children with respiratory condition is prescribed drugs each year at the United States, a new study concludes.

"We are trying to reduce unnecessary antibiotics prescriptions, and suggests that as pediatricians, we are prescribing them too often, said researcher principal Dr. Ian M. Paul, Associate Professor of Pediatrics at the Faculty of Medicine of the University of Pennsylvania, Hershey's State.".

Why doctors prescribe antibiotics for asthma is not clear, Paul said. One of the reasons could be that physicians in treatment of severe asthma attack "feel the need to cover all their bases in also prescribing antibiotics", he suggested.

Sometimes parents can ask doctors to give their child antibiotics, but it does not appear to be a big factor, Paul noted. "There are probably some in clinical practice, but I do not think that happens all that often - certainly not in one in every six visits for asthma," he said.

"The encouraging conclusion was, when asthma education delivered during the visit, antibiotics were less likely to be prescribed", he added. When asthma education was not part of the visit, 19% of the time antibiotics were prescribed, compared to 11% when the teaching of asthma has been given.

"This suggests that we can raise families and patients and explain the causes of asthma and, hopefully, reduce prescribe them unnecessary antibiotic", said Paul.

The dangers of over-prescribing antibiotics are that it encourages the development of antibiotic-resistant bacteria and there are side effects to drugs themselves, Paul said.

The report was published in the online edition may 23 of Pediatrics.

The study, the team used Paul data from the National ambulatory medical and hospital care surveys Ambulatory Medical Care survey to see the rate of antibiotics prescribed for children between 1998 and 2007.

During this period, there were a few 60.4 million visits of medical care for children with asthma for which no prescription of antibiotics was justified. However, antibiotics were prescribed 16 percent of the time, researchers have discovered.

Primary care physicians were more likely to prescribe antibiotics, while that emergency physicians are less likely to prescribe them, said Paul.

Other factors that are linked to increased antibiotic prescription included corticosteroids and treated in the winter, the researchers noted.

However, when visits to primary care doctors included asthma, education, the antibiotic prescription rate has declined, Paul said.

In a second study in the same journal, Belgian researchers, led by Dr. Kris De Boeck, the Department of pediatric pulmonology and infectious diseases at University Hospital of Leuven, are like overprescription of antibiotics for asthmatic children.

These researchers found children treated with asthma drugs were 1.9 times more likely to also obtain a prescription for antibiotics, compared to children not treated with drugs against asthma.

In fact, 35.6% of children who have been prescribed drugs against asthma was also prescribed antibiotics, the researchers found.

"This finding highlights the need for education opportunities inform clinicians that this co-prescription should be limited," the authors concluded.

Commenting on the two studies, Dr. Paul Krogstad, Professor of pediatric infectious diseases at the University of California, Los Angeles and co-author of an editorial in the magazine that accompanies it, said that "these articles indicate that antibiotics and anti-asthmatic were very commonly prescribed two tandem here and Belgiquequi is in conflict with national and international recommendations that emphasize that the" antibiotics have no systematic use in the care of asthmatics. ?

Antibiotic overuse confuses the patient and the family, said Krogstad. "They do not understand the true nature of asthma as an inflammatory, not an infectious disease,"he explained.""

In addition, over-prescribing antibiotics leads to personal risk and society, said Krogstad.

"Personal risks include allergic reactions, side effects, drug interactions and costs." Societal costs include the costs associated with the medication and the choice of drug-resistant bacteria. Antibiotic overuse is reduced, but this remains an area where improvement is badly needed, "he says.

Edurant approved to treat HIV/AIDS

Edurant (rilpivirine), in combination with other antiretroviral drugs, was approved by the Food and Drug Administration to treat the HIV-1 infection in adults who have not taken any prior treatment HIV

HIV is the virus that causes AIDS. Edurant, an inhibitor of the so-called non-nucleoside reverse transcriptase inhibitor (NNRTI), blocks the ability of the virus to reproduce. The pill is taken once a day with food, the FDA said in a press release.

Edurant was evaluated in a pair of 48 weeks of studies on 1 368 adults infected with HIV. Over the other NNRTIS, efavirenz, Edurant was also effective for reducing the quantities of virus in the blood of a person, the Agency said.

The most commonly reported side effects were depression, insomnia, headache and rash.

Given that Edurant not reverse HIV infection, people must continue to take the drug, in combination with other anti-HIV drugs, to prevent HIV-related disease, the FDA said.

Edurant is produced by Tibotec Therapeutics, based in Raritan, N.J.

Ebb with age driving skills: study

even healthy seniors with records of safe conduct, and no history of dementia tend to more potentially dangerous mistakes such as forgetting to check a blind spot, a new study.

This suggests that the driving performance declines with normal aging and more errors arise, putting seniors at risk of car accidents, said Australian researchers, who has proposed additional training in related cognitive skills for older drivers.

This suggestion, however, will be probably controversial.

"It's really hard to have the brain", said Renee Pekmezaris, vice President for health and community services in the Department of Population Health Research at North Shore Long Island Jewish health system in New York.

Other studies show that cognitive recycling does not reduce accidents of the conduct of the elderly, said Pekmezaris. "I'm not as good hope that the authors of the study on this subject," she said. "But there is something else we can do."

The study appeared online may 16 in Neuropsychology, a journal of the American Psychological Association.

In the study, researchers examined the driving habits of 266 healthy older drivers from 70 to 88 who lived independently and led at least once a week. In addition to complete questionnaires about their health and their history driving, seniors took tests on various skills at the wheel, such as discrimination, reaction time and ability to remain concentrated in distractions, or adapt to changing conditions.

In the 12-mile road test, a professional instructor with access to a brake mounted in the car. Occupational therapist seated on the seat back and scored pilots for skills such as the use of signals and mirrors, the "blind spot" and the problems which included veering, tailgating, improper braking and accelerating the verification.

Overall, 17 per cent of drivers made serious errors that require the instructor to seize the wheel or apply the brakes.

The rate of critical errors in older drivers from 85 to 89 (which had an average of almost four critical errors) was also four times greater than with these 70 to 74 years (which had on average less than 1).

The most common error is a failure to check the "blind spot" for the other vehicles. Pilots of Declaration of a previous accident on the questionnaire is more related to the observation errors and scored low on appropriate braking and Acceleration, the study found.

Tests performed on both women and men.

"The results correspond well with 30 years of previous research," said Harvey l. Sterns, a professor at Northeastern University Ohio Medical Gerontology research. Driving ability, in General, decreases with age, he said.

But Sterns cautioned that many seniors have no problem handling of a car. Some drivers in the group age studied no error, he said.

"There are greater differences in age between the age groups," said Sterns, also a Professor of Psychology at the University of Akron, Ohio. "It is difficult to know if [is] showing the spectacular changes from an earlier time."

In United States, 33 million drivers aged 65 and over were on the road in 2009, according to the Centers for Disease Control and Prevention. On average, 500 older adults are injured every day in car accidents, the Agency reported.

As the ageing of the population, the issue will increase in importance, said Sterns. Evidence of cognitive functions that are related to the conduct of skills is "a first step in important", said, noting that some of these functions could be improved with training.

The authors say that their findings are useful for the design of roads and signs, although they recognize that there are limits to their study. One is that the vision of the drivers was not assessed.

Said Pekmezaris aging drivers could do well to change their driving habits and take advantage of technological advances.

Older drivers may need to restrict their driving hours and make use of anti-reflective material and on-board anti-collision devices, she said.

"What we really need is for physicians involved in this", said Pekmezaris. Previous research has revealed that 89% of older drivers reported that they would stop driving if their doctor recommended, she said.

Side effects may influence choices of diabetes medications difficult to manage

THURSDAY, May 19- when a person with diabetes type 2 a need for a third drug of glycemic control, the choice may come to the drug has adverse effects, because the available drugs lower blood sugar in a similar way.

This is the conclusion of a new review data show that were there no large differences in the ability of the various classes of sugar drugs lower blood among the type 2 diabetics, when used as a "third party" treatment online (after a first and second drug is enough).

However, the study also found that some drugs may cause weight gain, and some episodes of low blood sugar (hypoglycemia).

In any event, "the type 2 diabetes is a progressive disease and most patients will need the combination of two or three hypoglycemic agents to achieve good glycemic control in the long term", noted author studyDr. Jorge gross, a Professor of medicine at Hospital de Clinicas Porto AlegreBrésil.

He explained: "selection of the third officer should be individualized according to the characteristics of the patients and the adverse effects of drugs, so you cannot elect an agent to be used in all patients with diabetes type 2"., ?.

The results of the study were published in this week of Annals of Internal Medicine.

Metformin, an older drug that is available as a generic, is generally recommended as a first line treatment for type 2 diabetes, with physical activity and diet changes. If metformin and lifestyle changes fail to control blood sugar well, a second drug is usually added.

For this study, researchers selected the commonly used combination of metformin and a sulfonylurea. Are usually available as generics and include drug of the sulfonylurea class: glyburide, glipizide, chlorpropamide, tolbutamide, and tolazamide.

"This study focused on what is probably the most common combination of drugs for diabetes, but even the second line therapy should be individualized based on the needs of the patient, said Dr. Robert Henry, Chairman of medicine and the sciences of the American Diabetes Association.".

Included alpha-glucosidase (acarbose) inhibitors, thiazolidinediones (which include Avandia and Actos), are investigating third-line drugs in the current of glucagon-like peptide-1 (GLP - 1) agonists and dipeptidyl peptidase-4 inhibitors (DPP-4).

The review included 18 clinical trials with a total of more than 4,500 people. Studies last for an average of more than 31 weeks.

When the researchers compared the reductions in rates of Hemoglobin A1C (HbA1C), they have not found any statistically significant difference between the third-line drugs. A1C is a blood test that measures long term (approximately two to three months) of blood glucose levels.

Weight gain was more frequent among people taking insulin or a thiazolidinedione. For those on insulin mean weight gain was approximately six books, according to the study. Those of the thiazolidinediones, mean weight gain was more than nine books.

3.6 Pounds in weight loss was observed in people taking GLP-1 agonists, reported in the study. Insulin is most likely to reduce blood glucose levels too, increase the chances of hypoglycemia, according to the study.

Dr. Joel Zonszein, Director of the Centre of clinical diabetes Montefiore Medical Center in New York City, noted that "they are mainly company drug studies and are not long term studies."

This review "shows that giving a third agent can help, and it also shows us that these drugs have effects of good and bad," said. "But we really need long term studies on the combinations that are not sponsored by pharmaceutical companies."

The bottom line, according to Zonszein: "each patient must be treated individually." They are obese? If Yes, there are certain drugs such as insulin and thiazolidinediones may cause weight gain, that we do not want. ?

When it comes to agents of the third line, said Henry, another factor may be price. Some drugs are not always available in generic form, making them much more expensive.

If you have specific concerns, such as weight gain or a price, said Henry it is important to bring these concerns to the attention of your doctor when you're talking about adding another medication for diabetes.

"If a third drug is necessary because blood sugar control is not appropriate, obtain a tailored to your specific needs," he advised.

"We believe that the results of this study offer a wide range of choice of hypoglycemic agents that could be used as the third option in patients of diabetes type 2 not controlled with metformin and sulfonylurea based on efficiency." "The final decision depends on the effects in the weight and risk of hypoglycemia," said Gross.

Postpartum depression more common in women victims of violence (HealthDay)

Thursday, May 19, HealthDay News) — Hispanic women who suffer violence during or shortly before becoming pregnant have an increased risk of five times from depression postpartum, U.S. researchers say.

The results suggest that intimate partner violence is a stronger indicator than prenatal depression postpartum depression, which is generally regarded as the most important risk factor.

The study of 210 Hispanic women aged 18 and older in Los Angeles found that women who have experienced violence during pregnancy or within 12 months of pregnancy are 5.4 times more likely to suffer from postpartum depression than those who had not undergone recent abuses.

The researchers also found that women who experienced prenatal depression were 3.5 times more likely to have postpartum depression than those with no experience antenatal depression.

These results indicate that pregnant women should be screened for prenatal depression and intimate partner violence, said researchers at the University of California, the Los Angeles Center for Culture, trauma and mental health disparities.

The study appears in the current issue of the mental health of the Archives of women.
