Massachusetts steps forward on health coverage
The most closely watched experiment in U.S. health care is under way in Massachusetts. Nearly everybody in the state is now required to have health insurance — or pay a tax penalty.
Massachusetts enacted its new health law in mid-2006 and has been phasing it in since. There's real progress to report. More of the uninsured have signed up than expected. Support remains broad and strong. But there have been glitches. And unless the federal government comes through with financing for the next phase, the experiment could still fall off the tracks.
The Price Of Complication Anytime you start with the complex U.S. health system as it is and try to plug its gaping holes, you're going to end up with something very complicated. That's what is happening in Massachusetts. And yes, Massachusetts health reform is very complicated. It's actually a collection of new programs.
Driving the whole thing is a new state requirement that all residents over 18 must have insurance — or pay a penalty of up to $912 on their annual income taxes.
The only exceptions are those who can't find an insurance policy that's "affordable" — no more than 2 to 10 percent of their gross annual income. About 60,000 people are expected to be exempt this year, but the number could rise if the cost of insurance keeps going up faster than people's incomes. So far, the Massachusetts law has exceeded its targets. Enrollment is running a year ahead of projections. The number of uninsured has dropped by more than half. Most of the newly insured are people who are poor or near-poor. Analysts say people's unmet health care needs have dropped substantially. Fewer people are hit by large medical bills and fewer are reporting trouble paying their bills. Nearly three out of four people think the new law has been a success, according to a recent poll of 1,015 randomly selected Massachusetts adults conducted by the Harvard School of Public Health for the Blue Cross Blue Shield of Massachusetts Foundation. Most people in the survey support requiring people to have health insurance. A large majority favor subsidizing premiums for low-income people. On the other hand, the program's very success means that costs are running hundreds of millions of dollars higher than projected. In some parts of the state, newly insured people report trouble finding a doctor with appointment slots. Some people who have tried to get insured have run into maddening bureaucratic snags. Others who were signed up have found themselves disenrolled for no apparent reason. One of the biggest challenges is persuading younger adults to buy coverage. According to a recent study in the journal Health Affairs, most who are still uninsured are young males with low incomes and good health. Despite the problems, the costs, the challenges, most Massachusetts residents want to see the law continued. Only one in eight favor repeal. The fate of the experiment rests with the Bush administration. The federal waiver that was needed to launch the Massachusetts reform expired on June 30, but has been extended temporarily. The federal government supplies substantial subsidy — about $360 million in fiscal 2009. The state has applied for a three-year renewal of the waiver, and negotiations are ongoing. The most closely watched experiment in U.S. health care is under way in Massachusetts. Nearly everybody in the state is now required t... more -
DIY breast checks 'harmful'
DIY breast checks may do more harm than good, a study has suggested.
Under current medical guidance from the Department of Health, women are advised to be "breast aware" by familiarising themselves with how they feel so they notice any changes.
But a review of research studies involving more than 380,000 women who regularly checked their breasts for lumps concluded that the practice had no effect on deaths from breast cancer.
It may even be detrimental as women who thought they found lumps underwent biopsies that turned out to be unnecessary.
Self examination led to twice as many biopsies that turned out to be negative for cancer than women who did not check their breasts.
"At present, screening by breast self-examination or physical examination (by a trained health worker) cannot be recommended," said study authors Jan Peter Kosters and Peter Gotzsche, from the Copenhagen-based Nordic Cochrane Centre.
However, they did not go as far as telling people to stop checking their breasts.
Dr Kosters said women should always "seek medical advice if they detect any change in their breasts that might be breast cancer".
However Maria Leadbeater, clinical nurse specialist at Breast Cancer Care, disagreed with the findings, saying: ""Most of the 44,000 cases of breast cancer diagnosed each year in the UK are detected by women themselves.
"The earlier that breast cancer is detected, the more likely it is that treatment will be successful.
"Being breast aware does not mean following a fancy routine - you just need to know what your breasts look and feel like normally in any way you feel comfortable.
"If you notice any unusual changes or have any worries, check them out with your GP." DIY breast checks may do more harm than good, a study has suggested. ... more -
Reason for dinosaur extinction may lie in this chart
Infoporn + Dinosaurs = Awesomeness.
"It has long been debated whether dinosaurs were part of the ‘Terrestrial Revolution’ that occurred some 100 million years ago during the Cretaceous when birds, mammals, flowering plants, insects and reptiles all underwent a rapid expansion.
An international study, led by the University of Bristol, shows that during their last 50 million years of existence, dinosaurs were not expanding as actively as had been previously thought and that the apparent explosion of dinosaur diversity may be largely explained by sampling bias.
The team produced a ‘supertree’ of dinosaurs, showing the most likely pattern of evolution for 440 of the 600 known species of dinosaur. "Supertrees are very large family trees made using sophisticated computer techniques that carefully stitch together several smaller trees which were previously produced by experts on the various subgroups”, explained lead author Graeme Lloyd.
“Our supertree summarises the efforts of two decades of research by hundreds of dinosaur workers from across the globe and allows to look for unusual patterns across the whole of dinosaurs for the first time." It is the most comprehensive picture ever produced of how dinosaurs evolved." Infoporn + Dinosaurs = Awesomeness. ... more -

Lots of sex but few orgasms for the Chinese
Really strange results just in from the Durex Sexual Wellbeing Global Survey this year: 78% of the Chinese have sex weekly, but only 24% were able to achieve an orgasm everytime they had sex. Any sexperts out there wanna tell us what insightful analysis one can make based on the above two statistics?
The Chinese might be top global performers when it comes to business, but during sex they appear to be struggling to reach their peak.
Couples from China and Hong Kong are the least likely to reach orgasm during sex, while the Italians and Spanish claim to have no problems climaxing, a global sex survey showed on Tuesday.
Less than a quarter -- 24 percent -- of those surveyed from China and Hong Kong were able to achieve an orgasm every time they had sex.
Italy, Spain and Mexico tied for top place, achieving orgasms 66 percent of the time, said the Durex Sexual Wellbeing survey, which polled 26,000 people in 26 countries.
The French, famous for their romantic overtures, came in at a middling 48 percent of the time -- the global average, the survey said.
Other Asian countries such as Japan and Singapore ranked poorly with those polled saying they only reached orgasm 27 percent and 36 percent of the time respectively.
Of those who manage to climax, the Japanese were the least satisfied with the intensity of the orgasm while Mexicans and Brazilians said they were the most satisfied.
Women climaxed less than men, with 32 percent saying they reached the peak every time they had sex, compared with 63 percent of men.
Factors that enhanced an orgasm included delaying climax, longer foreplay time and having a strong emotional relationship, the survey said.
The survey also found that while men preferred to orgasm with a partner, women achieved an orgasm more easily through masturbation.
"If you want to have an orgasm, it's important that you allow yourself to surrender to the good feelings you are experiencing," said Kevan Wylie, a sexual health expert, in a statement.

Researchers discover gene that regulates and blocks ovulation
A group of Canadian and European researchers have unlocked the mystery of a gene with the potential to both regulate and block ovulation. The new study — a collaboration between the Universite de Montreal in Canada and the Institut de genetique et biologie moleculaire et cellulaire of the Universite de Louis Pasteur, Strasbourg, France — is published in the latest issue of the journal Genes & Development.
"Our findings demonstrate that the Lrh1 gene is essential in regulating ovulation," said Bruce D. Murphy, director the Animal Research Centre at the Faculty of Veterinary Medicine and an adjunct professor of and obstetrics and gynaecology at the Faculty of Medicine of the Universite de Montreal. "Until this point, the role of Lrh1 in female fertility was unclear, but we have found the gene regulates multiple mechanisms of ovulation and may affect fertilization."
To reach their conclusions, the research team developed a new type of genetically modified mouse whose Lrh1 gene was selectively blocked in the ovary. They found that deletion of the Lrh1 gene effectively stopped ovulation. "This discovery means we can envision new contraceptives that selectively stop ovulation," said Dr. Murphy. "If created, these new contraceptives would be more effective and produce less side-effects than current steroid-based forms of birth control."
What’s more, the findings could lead to the development of pharmaceuticals that activate the Lrh1 gene, which may prove critical in giving infertile couples hope in producing children. "This is an important development, since 15 percent of couples are infertile," said Dr. Murphy. "The widespread role of this gene in the ovary indicates that it may be targeted to stimulate ovulation and, eventually, conception."

Pew Center and Toyota Team Up to Research Energy Efficiency Best Practices
The Pew Center on Global Climate Change and Toyota have launched a project to research energy efficiency strategies among top companies to discover, document and disseminate information about corporate best practices that reduce energy use and related greenhouse gas emissions.
The research and communications project, announced July 16, also will address the market and internal challenges companies encounter while attempting to implement energy efficiency strategies, Toyota and the Pew Center said.
The Pew Center is managing the research and communications for the project, which is being funded with a three-year, $1.4 million grant from Toyota.
"Energy efficiency is the simplest, most cost-effective way for companies to reduce their greenhouse gas emissions," said Eileen Claussen, president of the Pew Center on Global Climate Change, in a statement. "This project is designed to give companies the tools to ramp up efficiency efforts and simultaneously address growing concerns about climate change and skyrocketing energy prices."
Patricia Salas Pineda, group vice president of Toyota North America, praised the center's long experience in "engaging the business community in the development of pragmatic solutions to climate change."
"We are pleased to work with them to develop this initiative and educate corporations on the most effective ways to reduce energy use," Pineda said in a statement announcing the project.

Full medicinal pot uses explored
"Scottish and Swedish researchers say they are researching how to get full medicinal uses of marijuana without the side-effects.
Roger Pertwee of the University of Aberdeen and Christopher Fowler, Professor of Pharmacology at Umea University in Sweden, say marijuana is a source of compounds known as cannabinoids -- one of which, THC, the main chemical responsible for the marijuana "high," has been licensed as a medicine for suppressing nausea produced by chemotherapy and for stimulating appetite in AIDS patients.
More recently, the marijuana-based medicine Sativex was licensed both for the symptomatic relief of neuropathic pain in adults with multiple sclerosis and as an adjunctive analgesic treatment for adult patients with advanced cancer.
"THC works by targeting molecules in our bodies called cannabinoid receptors," Pertwee said in a statement. "So some current research is focused on designing drugs that only target cannabinoid receptors in the part of the body relevant to the disease in question and not the receptors in the central nervous system involved in the unwanted effects of cannabis."
Another constituent of marijuana, THCV, blocks one of the cannabinoid receptors that may provide an alternative treatment route in the fight against obesity, Pertwee said.
The findings are being presented at the Federation of European Pharmacological Societies in Manchester, England." "Scottish and Swedish researchers say they are researching how to get full medicinal uses of marijuana without the side-effects. ... more -
Rare coincidence of incurable juvenile dementia found in two toddlers in the same ...
Tragically, they are expected to die at any time in the next 10 to 12 years.
However, their tormented parents are now drawing comfort from one another after suddenly discovering they live only a few miles apart in the same UK town.
And their respective children have since become inseparable.
Baby Josh, aged 20 months, and toddler Hollie laugh and play together like normal children, unaware of their ticking timebomb plight.
The two families from Milton Keynes, Buckinghamshire, first heard about each other through a support group.
Hollie's mum, Helen Carter, said that both children had been diagnosed with the junior version of senile dementia after suffering prolonged jaundice at birth.
'They were both taken to King's College Hospital in London after they were born, where the disease was discovered following tests,' she said.
'One of the first symptoms of this is liver disease,' she added.
Soon the children will take part in vital research in America in the hope of providing a lifeline to future generations of Niemann-Pick type C (NPC) victims - the official name for juvenile dementia.
Selfless mothers Helen and Jodie want their offspring to leave a lasting legacy so their short lives won't have been wasted.
They are preparing themselves for the slow nightmare of watching their little ones develop the on-set of the illness.
Firstly, they will start to become clumsy, falling over and their memories will start to fade.
This will be followed by their sudden inability to walk, talk or feed themselves.
And, tragically, when the time comes for them to die, they are unlikely to even recognise their parents.
While the women are powerless to halt the progression of the illness, they are planning to take them to the National Institutes (corr) of Health in Maryland for trials.
Hollie's mother, Helen, aged 32 years, who is married to 39-year-old Pete, said: 'We are trying to raise funds for the trip because we have to do everything possible while there's still a flicker of hope.

Revolutionary filling-preventing mouthwash could replace the toothbrush in just t...
The dreaded dentist's drill and common toothbrush could become a thing of the past.
Scientists have created a solution that mimics the way the body forms new teeth - allowing natural repairs of holes without the need for drilling and filling.
Oral hygiene experts at Leeds Dental Institute have also made a mouthwash that kills plaque-making bacteria when a light is shone into the mouth.
They believed the new liquid could be available in less than three years - and perform the same job as using a toothbrush.
The mouthwash uses a molecule that is absorbed by bacteria in the mouth and destroys the harmful bug when it is activated by a bright light.
It is deemed safe as the molecule is already used by the food industry and not harmful if accidentally swallowed.
Called photo dynamic therapy, it was developed from a cancer treatment as a way of helping disabled people look after their mouths if they were unable to use a toothbrush.
The institute's research director, Professor Jennifer Kirkham, said the mouthwash could be used to treat gum disease and would only take a hygienist to perform the treatment.
She added: 'We feel confident that this is a major step change for the future.
'It is a safe way of improving oral hygiene for those patients for whom brushing is not feasible or as an adjunct to brushing.
'At the moment we are not saying it is going to take over brushing as the trials have not been done yet.
'We have now to look at how much it is going to cost. At the moment it is very cheap.'
The drilling alternative that uses a protein to naturally repair holes on the tooth's enamel, could be ready for patients within five years.
The compound works by creating a scaffold and attracting minerals that form enamel in the same way as the body creates teeth.
The chemical can be painted on teeth in small holes to prevent them decaying and becoming larger. The same treatment can be used to fill in tiny holes in teeth that cause them to become sensitive to hot and cold food and drinks.
The protein must pass British safety checks, which are currently underway. The institute is hopeful that trials will start early next year, with a view to getting a licence within five years.
Ultrasound could 're-grow' broken teeth in just 12 weeks
In a separate development, scientists revealed recently that teeth broken in an accident could soon be 'regrown' using an ultrasound machine half the size of a thumbnail.
The process could take just 12 weeks. Ultrasound is already used to help heal broken bones, now the technology is being applied to teeth.
Nanotechnology, which can reduce electronic circuitry to one thousandth of the size of a human hair, has enabled scientists to develop an ultrasound device small enough to fit inside the mouth.
A wafer-thin ultrasound chip, which is preprogrammed so that it turns on automatically, can be clipped onto the teeth. When it is on, ultrasound waves massage the gums to stimulate and increase blood flow to produce new tooth tissue.
The treatment takes just 20 minutes a day. The current version of the machine has a small handheld device which tells the patient when it is working.
Dr Tarek El-Bialy, of the University of Alberta in Edmonton, Canada, discovered the use of ultrasound to form new dental tissue from his research on rabbit incisors. He then moved on to humans and found similar results. The dreaded dentist's drill and common toothbrush could become a thing of the past. ... more -
Warning Over Deadly New Diseases
A potentially deadly new disease is emerging somewhere in the world every year - and the international community is ill-equipped to stop it spreading, a parliamentary committee has warned.
In a highly critical new report, the committee said there was an "urgent need" for a better global surveillance system to identify diseases before they infect large numbers of people.
It noted that three-quarters of newly-emerging human infections come from animals - but found many are only detected once they have made humans ill.
Experts estimate a devastating pandemic outbreak of a new disease such as SARS or the H5N1 strain of flu could claim anything between two and 50 million lives.
In evidence to the House of Lords Intergovernmental Organisations Committee inquiry, the Government said there had been no pandemic disease outbreaks since 1968.
However, it warned another pandemic outbreak was "inevitable".
Committee chairman Lord Soley said: "The last 100 years have seen great advances in public health and disease control through the world, but globalisation and changes in lifestyles are giving rise to new infections and providing opportunities for them to spread rapidly throughout the world.
"We have been impressed by the increased international resources and commitment which are now being devoted to controlling infectious diseases, and we hope this will continue and grow.
"However, for that to be effective it is vital that there is sufficient surveillance of disease outbreaks to limit their spread.
"We were particularly concerned about the link with animal health. Three quarters of new human infectious diseases start in animals.
"We urgently need better surveillance systems to deal with this problem."
The committee has called on the World Health Organisation to take a leadership role in improving coordination of the surveillance and response effort.
But it warned the UN agency needed to be "better organised and resourced" to do this. A potentially deadly new disease is emerging somewhere in the world every year - and the international community is ill-equipped to st... more -
Study finds genetic link to violence, delinquency
Genes may play an important role in determining why some young men raised in rough neighborhoods or deprived families become violent criminals while others do not, accordidng to the August issue of the American Sociological Review as quoted by media Tuesday.
One gene called MAOA that plays an especially strong role has been shown in other studies to affect antisocial behavior -- and it is disturbingly common, according to the team at the University of North Carolina.
People with a particular variation of the MAOA gene called 2R were very prone to criminal and delinquent behavior, said sociology professor Guang Guo, who led the study.
"I don't want to say it is a crime gene, but 1 percent of people have it and scored very high in violence and delinquency," Guo said in a telephone interview with media.
Guo's team found specific variations in three genes -- the monoamine oxidase A (MAOA) gene, the dopamine transporter 1(DAT1) gene and the dopamine D2 receptor (DRD2) gene -- were associated with bad behavior.
Guo's team, which studied only boys, used data from the National Longitudinal Study of Adolescent Health, a nationally representative sample of about 20,000 adolescents in grades 7 to 12. The young men in the study were interviewed in person regularly, and some gave blood samples.
His team constructed a "serious delinquency scale" based on some of the questions the youngsters answered.
"Nonviolent delinquency includes stealing amounts larger or smaller than 50 U.S. dollars, breaking and entering, and selling drugs," it wrote in the Review.
"Violent delinquency includes serious physical fighting that resulted in injuries needing medical treatment, use of weapons to get something from someone, involvement in physical fighting between groups, shooting or stabbing someone,deliberately damaging property, and pulling a knife or gun on someone." Genes may play an important role in determining why some young men raised in rough neighborhoods or deprived families become violent c... more -

ABSTRACT.
Objective. To identify neurobehavioral effects of prenatal marijuana exposure on neonates in rural Jamaica.
Design. Ethnographic field studies and standardized neurobehavior assessments during the neonatal period.
Setting. Rural Jamaica in heavy-marijuana-using population.
Participants. Twenty-four Jamaican neonates exposed to marijuana prenatally and 20 nonexposed neonates.
Measurements and main results. Exposed and nonexposed neonates were compared at 3 days and 1 month old, using the Brazelton Neonatal Assessment Scale, including supplementary items to capture possible subtle effects. There were no significant differences between exposed and nonexposed neonates on day 3. At 1 month, the exposed neonates showed better physiological stability and required less examiner facilitation to reach organized states. The neonates of heavy-marijuana-using mothers had better scores on autonomic stability, quality of alertness, irritability, and self-regulation and were judged to be more rewarding for caregivers.
Conclusions. The absence of any differences between the exposed on nonexposed groups in the early neonatal period suggest that the better scores of exposed neonates at 1 month are traceable to the cultural positioning and social and economic characteristics of mothers using marijuana that select for the use of marijuana but also promote neonatal development.

Pot "gateway theory" is backwards
A groundbreaking study of 4117 marijuana smokers in California reveals that the 'Gateway Theory' probably had it backwards. Instead of enticing young people to use other drugs, this study suggests that marijuana may have the opposite effect.
This first-ever clinical examination of a large number of medical marijuana applicants depicts a population that is remarkably normal. The percentages earning bachelors' degrees and doctorates are nearly identical to the national numbers. They are, in the main, productive citizens with jobs, homes and families who smoke marijuana weekly or daily and have in some cases for decades.
For the vast majority of these applicants, their use of cannabis ultimately led to a decrease in the use of tobacco, alcohol, and hard drugs. Asked to compare their current alcohol consumption with their lifetime peak, over 10% claimed to be abstinent and nearly 90% claimed to have cut their drinking in half.
They also report using cannabis as self medication for stress and anxiety with fewer side effects than the legal pharmaceutical alternatives.
As children, a significant percentage of the male applicants had been treated for ADHD (Attention Deficit Hyperactivity Disorder). Today their routine morning use of minimal amounts of cannabis strongly suggests that it enhances their ability to concentrate by allowing them to focus on one problem at a time.

Minute quantities of a bacterial protein inserted in corn provoke immune reactions in mice. The protein is added to increase the effectiveness of plant-based transgenic vaccines. The results indicate that special care will be needed with transgenic corn to reduce exposure to workers and the public if this protein is used commercially in corn or other food crops, to avoid unwanted immune responses in people and decreased effectiveness of oral vaccines that use the protein.

Use it or lose it: lots of sex may prevent erectile dysfunction
Frequent sexual intercourse may cut down on a man's chances of developing erectile dysfunction, Finnish researchers report.
"This is the same as any other part of the body. It's what we in vascular surgery refer to as the 'use it or lose it' concept," said Dr. Hossein Sadeghi-Nejad, an associate professor of urology at UMDNJ New Jersey Medical School Hackensack University Medical Center. "Sexual activity will promote maintenance of normal erectile function down the line."
The report was published in the July issue of The American Journal of Medicine.
In the study, led by Dr. Juha Koskimaki, from Tampere University Hospital's Department of Urology, researchers collected data on 989 Finnish men aged 55 to 75 years old.
The researchers found that men who said they had sexual intercourse less than once a week had twice the risk of developing erectile dysfunction, compared with men reporting having sexual intercourse once a week.
Among men who had sexual intercourse less than once a week, there were 79 cases of erectile dysfunction per 1,000 men. That number dropped to 32 cases per 1,000 among men who said they had sexual intercourse once a week, and it dropped even further, to 16 per 1,000, among men who said they had sexual intercourse three or more times a week, the researchers reported.
