Doctors eye chemicals for rise in child cancers

By Agence France-Presse
Wednesday, January 26th, 2011 -- 11:03 pm

WASHINGTON — A mom whose four-year-old died after losing a battle to a brain tumor called Wednesday for tougher US regulation of chemicals suspected of being behind a rise in childhood cancers.
"There's growing evidence linking toxic chemicals and carcinogens in the environment with childhood cancer," Christine Brouwer told a telephone news conference as she described losing a child to cancer.
"I'll most likely never know what caused my daughter's cancer, but researchers are finding more and more links between the hazardous substances in our homes and workplaces and cancer and other diseases."
Brouwer's daughter Mira underwent several operations and endured painful and nauseating treatments to try to beat the cancer she was diagnosed with just before her second birthday, on January 27, 2004.
After several rounds of surgery and months of treatment, Mira's cancer went into remission and she seemed to have won her fight against the ailment.
But it came back on her fourth birthday, killing her weeks later.
Her family questioned why the child was struck by such a serious illness so young, and Brouwer's suspicions turned toward the chemicals found in cleaning fluids for the floors that babies crawl on, in the plastic of the bottles they drink from and in some of the foods they and their parents eat.
Boston University professor of environmental health Richard Clapp said the incidence of childhood cancer in the United States has grown about one percent a year for the past two decades.
"It's clear that at least one component of the cause is environmental chemical exposure," he said.
Epidemiologists have linked chlorinated solvents to childhood leukemia and other solvents to brain cancer in children, said Clapp, who served as director of the Massachusetts Cancer Registry for 10 years in the 1980s.
Pediatrician Sean Palfrey said doctors suspect chemicals and other environmental pollutants are behind a rise in everything from cancer to allergies to asthma in children.
"The problem with our current situation is that we are putting so many chemicals out into our environment, and our bodies have no idea how to detoxify them, don't know how to prevent them being absorbed," he said, calling for tougher US laws on chemicals.
Brouwer, Clapp and Palfrey were participating in a news conference organized by the Safer Chemicals, Healthy Families advocacy group, which says the 35-year-old Toxic Substances Control Act does not cover the vast majority of chemicals in US consumer products and urgently needs an overhaul.

COMMENT: YES, "the 35-year-old Toxic Substances Control Act does not cover the vast majority of chemicals in US consumer products and urgently needs an overhaul", AND I am sorry this woman's daughter died.


HOWEVER... how much vit C was she getting? How much vit D? How much iodine? How much (organic) animal fat, nut fat, and fruit fat? Did she go to bed before midnight, sleep in darkness and quiet, and not get up til after dawn?

Conversely, how much grain and sugar was she consuming?

The five most powerful heart disease prevention strategies
Dr. William Davis
The Heart Scan Blog 
Sunday, January 23, 2011

You've seen such lists before: 5 steps to prevent heart disease or some such thing. These lists usually say things like "cut your saturated fat," eat a "balanced diet" (whatever the heck that means), exercise, and don't smoke.

I would offer a different list. You already know that smoking is a supremely idiotic habit, so I won't repeat that. Here are the 5 most important strategies I know of that help you prevent heart disease and heart attack:

1) Eliminate wheat from the diet--Provided you don't do something stupid, like allow M&M's, Coca Cola, and corn chips to dominate your diet, elimination of wheat is an enormously effective means to reduce small LDL particles, reduce triglycerides, increase HDL, reduce inflammatory measures like c-reactive protein, lose weight (inflammation-driving visceral fat), reduce blood sugar, and reduce blood pressure. I know of no other single dietary strategy that packs as much punch. This has become even more true over the past 20 years, ever since the dwarf variant of modern wheat has come to dominate.

2) Achieve a desirable 25-hydroxy vitamin D level--Contrary to the inane comments of the Institute of Medicine, vitamin D supplementation increases HDL, reduces small LDL, normalizes insulin and reduces blood sugar, reduces blood pressure, and exerts potent anti-inflammatory effects on c-reactive protein, matrix metalloproteinase, and other inflammmatory mediators. While we also have drugs that mimic some of these effects, vitamin D does so without side-effects.

3) Supplement omega-3 fatty acids from fish oil--Omega-3 fatty acids reduce triglycerides, accelerate postprandial (after-meal) clearance of lipoprotein byproducts like chylomicron remnants, and have a physical stabilizing effect on atherosclerotic plaque.

4) Normalize thyroid function--Start with obtaining sufficient iodine. Iodine is not optional; it is an essential trace mineral to maintain normal thyroid function, protect the thyroid from the hundreds of thyroid disrupters in our environment (e.g., perchlorates from fertilizer residues in produce), as well as other functions such as anti-bacterial effects. Thyroid dysfunction is epidemic; correction of subtle degrees of hypothyroidism reduces LDL, reduces triglycerides, reduces small LDL, facilitates weight loss, reduces blood pressure, normalizes endothelial responses, and reduces oxidized LDL particles.

5) Make exercise fun--Not just exercise for the sake of exercise, but physical activity or exercise for the sake of having a good time. It's the difference between resigning yourself to 30 minutes of torture and boredom on the treadmill versus engaging in an activity you enjoy and look forward to: go dancing, walk with a friend, organize a paintball tournament outdoors, Zumba class, plant a new garden, etc. It's a distinction that spells the difference between finding every excuse not to do it, compared to making time for it because you enjoy it.

Note what is not on the list: cut your fat, eat more "healthy whole grains," take a cholesterol drug, take aspirin. That's the list you'd follow if you feel your hospital needs your $100,000 contribution, otherwise known as coronary bypass surgery.

Study: Many college students not learning to think critically

last updated: January 17, 2011 04:52:23 PM

NEW YORK — An unprecedented study that followed several thousand undergraduates through four years of college found that large numbers didn't learn the critical thinking, complex reasoning and written communication skills that are widely assumed to be at the core of a college education.
Many of the students graduated without knowing how to sift fact from opinion, make a clear written argument or objectively review conflicting reports of a situation or event, according to New York University sociologist Richard Arum, lead author of the study. The students, for example, couldn't determine the cause of an increase in neighborhood crime or how best to respond without being swayed by emotional testimony and political spin.

Arum, whose book "Academically Adrift: Limited Learning on College Campuses" (University of Chicago Press) comes out this month, followed 2,322 traditional-age students from the fall of 2005 to the spring of 2009 and examined testing data and student surveys at a broad range of 24 U.S. colleges and universities, from the highly selective to the less selective.

Forty-five percent of students made no significant improvement in their critical thinking, reasoning or writing skills during the first two years of college, according to the study. After four years, 36 percent showed no significant gains in these so-called "higher order" thinking skills.
Combining the hours spent studying and in class, students devoted less than a fifth of their time each week to academic pursuits. By contrast, students spent 51 percent of their time — or 85 hours a week — socializing or in extracurricular activities.

The study also showed that students who studied alone made more significant gains in learning than those who studied in groups.

"I'm not surprised at the results," said Stephen G. Emerson, the president of Haverford College in Pennsylvania. "Our very best students don't study in groups. They might work in groups in lab projects. But when they study, they study by themselves."

The study marks one of the first times a cohort of undergraduates has been followed over four years to examine whether they're learning specific skills. It provides a portrait of the complex set of factors, from the quality of secondary school preparation to the academic demands on campus, which determine learning. It comes amid President Barack Obama's call for more college graduates by 2020 and is likely to shine a spotlight on the quality of the education they receive.

"These findings are extremely valuable for those of us deeply concerned about the state of undergraduate learning and student intellectual engagement," said Brian D. Casey, the president of DePauw University in Greencastle, Ind. "They will surely shape discussions about curriculum and campus life for years to come."

Some educators note that a weakened economy and a need to work while in school may be partly responsible for the reduced focus on academics, while others caution against using the study to blame students for not applying themselves.

Howard Gardner, a professor at Harvard's Graduate School of Education known for his theory of multiple intelligences, said the study underscores the need for higher education to push students harder.
"No one concerned with education can be pleased with the findings of this study," Gardner said. "I think that higher education in general is not demanding enough of students — academics are simply of less importance than they were a generation ago."

But the solution, in Gardner's view, shouldn't be to introduce high-stakes tests to measure learning in college because, "The cure is likely to be worse than the disease."

Arum concluded that while students at highly selective schools made more gains than those at less selective schools, there are even greater disparities within institutions.

"In all these 24 colleges and universities, you have pockets of kids that are working hard and learning at very high rates," Arum said. "There is this variation across colleges, but even greater variation within colleges in how much kids are applying themselves and learning."

For that reason, Arum added, he hopes his data will encourage colleges and universities to look within for ways to improve teaching and learning.

Arum co-authored the book with Josipa Roksa, an assistant professor of sociology at the University of Virginia. The study, conducted with Esther Cho, a researcher with the Social Science Research Council, showed that students learned more when asked to do more.

Students who majored in the traditional liberal arts — including the social sciences, humanities, natural sciences and mathematics — showed significantly greater gains over time than other students in critical thinking, complex reasoning and writing skills.
Students majoring in business, education, social work and communications showed the least gains in learning. However, the authors note that their findings don't preclude the possibility that such students "are developing subject-specific or occupationally relevant skills."

Greater gains in liberal arts subjects are at least partly the result of faculty requiring higher levels of reading and writing, as well as students spending more time studying, the study's authors found. Students who took courses heavy on both reading (more than 40 pages a week) and writing (more than 20 pages in a semester) showed higher rates of learning.
That's welcome news to liberal arts advocates.
"We do teach analytical reading and writing," said Ellen Fitzpatrick, a history professor at the University of New Hampshire.

The study used data from the Collegiate Learning Assessment, a 90-minute essay-type test that attempts to measure what liberal arts colleges teach and that more than 400 colleges and universities have used since 2002. The test is voluntary and includes real world problem-solving tasks, such as determining the cause of an airplane crash, that require reading and analyzing documents from newspaper articles to government reports.

The study's authors also found that large numbers of students didn't enroll in courses requiring substantial work. In a typical semester, a third of students took no courses with more than 40 pages of reading per week. Half didn't take a single course in which they wrote more than 20 pages over the semester.
The findings show that colleges need to be acutely aware of how instruction relates to the learning of critical-thinking and related skills, said Daniel J. Bradley, the president of Indiana State University and one of 71 college presidents who recently signed a pledge to improve student learning.

"We haven't spent enough time making sure we are indeed teaching — and students are learning — these skills," Bradley said.

Christine Walker, a senior at DePauw who's also student body president, said the study doesn't reflect her own experience: She studies upwards of 30 hours a week and is confident she's learning plenty. Walker said she and her classmates are juggling multiple non-academic demands, including jobs, to help pay for their education and that in today's economy, top grades aren't enough.

"If you don't have a good resume," Walker said, "the fact that you can say, 'I wrote this really good paper that helped my critical thinking' is going to be irrelevant."

Thirteen catheterizations later

Dr. William Davis 
The Heart Scan Blog
Thursday, January 20, 2011

When I first met her, Janet couldn't stop sobbing. She'd just been through her 10th heart catheterization in two years.

It started with chest pains at age 56, prompting her first heart catheterization that uncovered severe atherosclerotic blockages in all three coronary arteries. Her cardiologist advised a bypass operation.

Six months after the bypass operation, Janet was back with more chest pains, just as bad as before. Another heart catherization showed that two of the three bypass grafts had failed. The third bypass graft contained a severe blockage that required a stent, along with multiple stents in the two now unbypassed arteries.

In the ensuing 18 months, Janet returned for 8 additional catheterizations, each time leaving the hospital with one or more stents.

Janet's doctor was puzzled as to why her disease was progressing so aggressively despite Lipitor and the low-fat diet provided by the hospital dietitian. So he had Janet undergo lipoprotein testing (NMR):

LDL particle number: 3363 nmol/L
Small LDL particle number: 2865 nmol/L
HDL cholesterol: 32 mg/dl
Triglycerides: 344 mg/dl
Fasting blood glucose 118 mg/dl
HbA1c 5.8%

Unfortunately, Janet's doctor didn't understand what these values meant. He pretty much threw his arms up in frustration. That's when I met Janet.

From her lipoprotein panel and other values, it was clear to me that Janet was miserably carbohydrate-sensitive and carbohydrate-indulgent, as demonstrated by the extravagant quantity (2865 nmol/L) and proportion (2865/3363, or 85%) of small LDL, the form of LDL particles created by carbohydrate exposure. Janet struggled with depression over the years and had been using carbohydrate foods as "comfort" foods, often resorting to cookies, pies, cakes, breads, and other wheat-containing foods for emotional solace.

It took a bit of persuasion to convince Janet that it was low-fat, "healthy whole grains," as well as comfort foods, that had led her down this path. I also helped Janet correct her severe vitamin D deficiency, mild thyroid dysfunction, and lack of omega-3 fatty acids.

Since meeting Janet and instituting her new prevention program, she has undergone three additional catheterizations (performed by another cardiologist), all performed for chest pain symptoms that struck during periods of emotional stress. All showed . . . no significant blockage. (Apparently, the repeated "need" for stents triggered a Pavlovian response: chest pain = "need" for yet more stents.)

In short, correction of the causes of coronary atherosclerotic plaque--small LDL, vitamin D deficiency, omega-3 fatty acid deficiency, and thyroid dysfunction--and Janet's disease essentially ground to a halt.

Imagine, instead, that Janet had undergone 1) a heart scan to identify hidden coronary plaque 5-10 years before her first heart procedure, then 2) corrected the causes before they triggered symptoms and posed danger. She might have been spared an extraordinary amount of life crises, hospital procedures, expense (nearly $1 million), and emotional suffering.

Night owls may want to dim their lights 


Study finds that that night-time lighting reduces hormone associated with sleep and health
Web edition : Wednesday, January 12th, 2011

People who spend their evenings in relatively bright light run the risk of stressing their bodies by ratcheting down the production of melatonin. Produced in the brain's pineal gland, this hormone plays a pivotal role in setting the body’s biological clock – and, potentially, in limiting the development of certain cancers. More than 100 young adults volunteered for a roughly 10-day research trial during which each took turns living in a light-controlled room at Brigham and Women’s Hospital in Boston. From midnight until 8 a.m. the room was totally dark. At other times, researchers from Harvard Medical School tinkered with the room’s lighting.
On most evenings, the illumination averaged 200 lux (or roughly the brightness of a normal living room at night); on other evenings, it was no brighter than 3 lux (what might be expected from three candles burning at a distance of 1 meter.)
When their room’s lighting had been bright, the participants made, on average, 71 percent less melatonin in the hours before sleep. Their bodies also commenced production of the hormone substantially later on nights when the lighting was brighter – just 23 minutes before scheduled sleep time (midnight) versus almost 2 hours before bedtime when the lighting had been dim.
What’s more, the body didn’t fully catch up for any late start on melatonin synthesis. The day's production fell short by about 12.5 percent after an evening when the lighting was bright.
And it gets worse if people pull all-nighters, Joshua J. Gooley and his colleagues found. In a second, smaller trial involving just 12 volunteers, they let the participants spend a few days adjusting to a normal day-night lighting routine in the test room. Then came a 40-hour cycle of constant light at the 200 lux level.
Eleven people went through this ordeal once. The twelfth endured it twice. And in 11 of the 13 trials, the recruits sustained a dramatic reduction in melatonin production – of at least 51 percent; in six trials the hormone shortfall ranged from 76.9 to 92.5 percent. This experiment established that “exposure to room light in participants who were kept awake during the usual hours of sleep suppressed melatonin by more than half the amount measured during sleep in darkness,” Gooley’s team reports in the Journal of Clinical Endocrinology & Metabolism.
 Their paper, slated to appear in March, has been posted early online.
“Given that chronic light suppression of melatonin has been hypothesized to increase risk for some types of cancer and that melatonin-receptor genes have been linked to type 2 diabetes, our findings could have important health implications for shift workers who are exposed to indoor light at night over the course of many years,” Gooley says.
Richard Stevens of the University of Connecticut Health Center, in Farmington, goes farther. “I think – hope – that this paper will be seen as a turning point.” For what? For the possibility that the typical nighttime illumination to which almost all people in the modern world (not just shift workers) are exposed might actually pose a health risk, especially for breast cancer.”
Until a seminal 1980 paper in Science, “it was thought that humans, unlike other animals, were insensitive to light during the night,” Stevens says. Seven years later, when he published a paper hypothesizing that light at night might foster breast cancer, plenty of people scoffed. Indeed, he recalls, “Nobody thought room light from electric bulbs was adequate to suppress melatonin.”
The JCEM paper, he says, now suggests that indoor lighting at night not only lowers melatonin, but also alters the rhythmic cycles of the body’s clock. And that, he contends, means that light at night “could be a problem for any malady for which [those] circadian rhythms might matter -- like breast cancer.”


-------------------------------------------------------------
COMMENT: Despite the sometimes valid criticisms of Wikipedia, their article on Phase Response Curve is actually quite good. Basically, dim light two hours before bedtime, sleep in complete darkness, then bright light within the two hours after you get up. The link in that article to light therapy may be helpful.

Fox shoots man

– Thu Jan 13, 2:50 pm ET MOSCOW (Reuters) – A wounded fox shot its would be killer in Belarus by pulling the trigger on the hunter's gun as the pair scuffled after the man tried to finish the animal off with the butt of the rifle, media said Thursday.
The unnamed hunter, who had approached the fox after wounding it from a distance, was in hospital with a leg wound, while the fox made its escape, media said, citing prosecutors from the Grodno region.
"The animal fiercely resisted and in the struggle accidentally pulled the trigger with its paw," one prosecutor was quoted as saying.
Fox-hunting is popular in the picturesque farming region of northwestern Belarus which borders Poland.

COMMENT: Humans are predator animals; we have eyes in the front of our heads - giving up wider field of vision for depth perception - and, although we eat some plant food, we definitely need to eat some animal food to be healthy. PREDATORS ARE NOT PREY. Hunting foxes - our fellow predator animals - is COMPLETELY unacceptable.


Those who cannot tell the difference between predators and prey are not fit for existence.

Cause of schizophrenia found?

Press Trust Of India
Posted on Jan 12, 2011 at 03:07pm IST
 
Washington: In what could be a possible cause of schizophrenia, scientists claim to have found a link between the condition and trapped brain cells that are unable to reach the cortex, the brain's outer part.
A new study, led by University of New South Wales, has claimed that brain cells might become "stuck" in their journey during brain development to the outer "thinking" layer of the brain, which could be a cause of schizophrenia.
The scientists have found that in people with schizophrenia, brain cells destined for the cortex - the outer part of the brain associated with thinking and other cognitive abilities - could get trapped in the layer below.
"We think brain cells might be trapped while in the process of migrating to the cortex while the brain develops. This process of neuronal migration to the cortex doesn't stop at birth. It's robust in infants and may continue in teenage
years and beyond.
"We know that brain development is derailed somehow in people with schizophrenia, and this study helps us understand how," said lead scientist Professor Cyndi Shannon Weickert.
The next step is to understand why these neurons are failing to complete their journey to the cortex, according to the scientists.
"Then maybe we can develop a therapy that encourages the neurons to keep moving to the finish line. Our hope is that this would reduce symptoms or even prevent schizophrenia from developing at all," she said.
The findings have been published in the latest edition of the 'Biological Psychiatry' journal. 

------------------------------------------------------------------
COMMENT: Oh, Jesus Christ. 

FIRST, Drs. Abram Hoffer and Carl Pfeiffer already found the causeS and cureS of the schizophreniaS back in the 1960's and 1970's. Niacin, vit C, and either a low- or high-copper diet (as appropriate in each case) are proven safe and effective. The Medical BUSINESS is threatened by nutrition, and simply lies about it.

SECOND, some of the people who develop schizophrenia are those who could become shamans; when they show this "developmental potential", the Control System freaks out. Hence, the desperate attempt to prevent it from happening. The U.S.A., for example, is a tribe of over 300 million - and zero shamans; no wonder everyone's going insane.
