Most diabetics falling short on healthy eating

Diabetes mellitus is a disease characterized by persistent hyperglycemia (high blood sugar levels), resulting either from inadequate secretion of the hormone insulin, an inadequate response of target cells to insulin, or a combination of these factors. Diabetes is a metabolic disease requiring medical diagnosis, treatment and lifestyle changes.

There are many causes and forms of diabetes known. The three most common patterns of diabetes have been recognized over the last thirty years as type 1, type 2 and gestational diabetes (or type 3)[1], although these three “types” of diabetes are more accurately considered patterns of pancreatic failure rather than single diseases. Each type can be produced by a variety of identifiable or yet-to-be-identified causes. There are some patients whose diabetes cannot be easily fit into one of these types, and some who display characteristics of more than one type at the same time.

Most Americans with diabetes are eating too much fat and sodium, and not enough fruits, vegetables, grains and low-fat dairy, a new study suggests.

The results, say researchers, indicate that many people with diabetes may need more education about the importance of nutrition in managing their condition.

Excess weight is one of the major risk factors for type 2 diabetes, a disorder in which the body can no longer properly use the blood sugar-regulating hormone insulin. Diet, exercise and weight loss are key to managing the disorder, and in some cases, weight loss can reverse the condition.

Yet in the new study, researchers found that of nearly 2,800 middle- aged and older U.S. adults with type 2 diabetes, nearly all were exceeding the daily recommended fat intake. When it came to artery-clogging saturated fat, 85 percent were consuming too much.

Similarly, 92 percent of study participants were consuming too much sodium, which can raise blood pressure and contribute to diabetics’ already elevated risks of heart disease and kidney disease. (See related Reuters Health story today.)

The researchers used a number of nutritional yardsticks, including the Food Guide Pyramid and recommendations by the Institute of Medicine. For example, experts recommend that adults get no more than 20 percent to 35 percent of their daily calories from fat, with less than 10 percent coming from saturated fat.

And if most study participants were getting too much of those nutrients, many were also not getting enough of certain healthy foods, the researchers report in the Journal of the American Dietetic Association.

Less than half were getting the minimum recommended servings of fruits, vegetables, dairy and grains each day.

“I thought we were going to find people who, because they have a chronic disease, were more educated about and more motivated than the average American to eat healthy, but that’s not the case,” lead researcher Dr. Mara C. Vitolins, of Wake-Forest University School of Medicine in Winston-Salem, North Carolina, said in a written statement.

Cancer drug crosses key hurdle in brain: study

An experimental drug appears to cross a protective barrier in the brain that screens out most chemicals, offering potentially better ways to treat brain tumors, U.S. researchers said on Sunday.

The drug, made by privately held Angiochem Inc of Montreal was safe and showed evidence it could shrink tumors in two separate early phase studies totaling more than 100 people with a brain cancer called glioblastoma.

It also worked among people whose cancers had spread or metastasized to the brain, the researchers reported at the annual meeting of the Society for Neuroscience in Chicago.

In both studies, tumors shrank in patients who got a higher dose of the drug, called ANG1005. The drug also showed signs of working in patients whose cancers resisted the chemotherapy drug taxane.

“It is highly encouraging to see that ANG1005 has shown the potential to be effective in metastatic brain cancers and against drug-resistant tumors,” Dr. Jan Drappatz of Dana-Farber Cancer Institute and Brigham and Women’s Hospital in Boston, who is studying the drug, said in a statement.

Drappatz said tumors shrank significantly in some patients and some neurological problems were reversed in several.

Studies of brain tumor samples showed concentrations of the drug in the tumors, proving it successfully crossed the blood-brain barrier and accumulated.

Made up of a network of blood vessels, the blood-brain barrier prevents 95 percent of all chemicals from leaving the bloodstream and entering the brain.

Psychic Surgery – Conclusion

[media id=27 width=500 height=400]

Psychic surgery

Psychic surgery is a procedure typically involving the apparent creation of an incision using only the bare hands, the apparent removal of pathological matter, and the seemingly spontaneous healing of the incision.

Psychic surgery has been condemned in many countries as a form of medical fraud. It has been denounced by the US Federal Trade Commission as a “total hoax “and the American Cancer Society maintains that psychic surgery may cause needless death by keeping the ill away from life-saving medical care.Medical professionals and skeptics consider it sleight of hand and any positive results a placebo effect.

It first appeared in the Spiritualist communities of the Philippines and Brazil in the mid-1900s, and it has taken different paths in those two countries.

Procedure

Although psychic surgery varies by region and practitioner, it usually follows some common lines. Without the use of a surgical instrument, a practitioner will press the tips of his/her fingers against the patient’s skin in the area to be treated. The practitioner’s hands appear to penetrate into the patient’s body painlessly and blood seems to flow. The practitioner will then show organic matter or foreign objects apparently removed from the patient’s body, clean the area, and then end the procedure with the patient’s skin showing no wounds or scars.

Most cases do not involve actual surgery although some practitioners make real incisions. The practitioners are using sleight of hand techniques to produce blood or blood-like fluids, animal tissue or substitutes, and/or various foreign objects from folds of skin of the patient as part of a confidence game for financial benefit of the practitioner.

Two psychic surgery practitioners provided testimony in an Federal Trade Commission trial that, to their knowledge, the organic matter apparently removed from the patients usually consists of animal tissue and clotted blood. In regions of the world where belief in evil spirits is prevalent, practitioners will sometimes exhibit objects, such as glass, explaining that the foreign bodies were placed in the patient’s body by evil spirits.

History

Accounts of psychic surgery started to appear in the Spiritualist communities of the Philippines and Brazil in the mid-1900s.

Philippines

In the Philippines, the procedure was first noticed in the 1940s, when performed routinely by Eleuterio Terte. Terte and his pupil Tony Agpaoa, who was apparently associated with the Union Espiritista Christiana de Filipinas (The Christian Spiritist Union of the Philippines), trained others in this procedure.

In 1959, the procedure came to the attention of the U. S. public after the publication of Into the Strange Unknown by Ron Ormond and Ormond McGill. The authors called the practice “fourth dimensional surgery,” and wrote “[we] still don’t know what to think; but we have motion pictures to show it wasn’t the work of any normal magician, and could very well be just what the Filipinos said it was — a miracle of God performed by a fourth dimensional surgeon.”

Alex Orbito, who became well-known in the U. S. through his association with actress Shirley MacLainewas one said practitioner of the procedure. On June 14, 2005, Orbito was arrested by Canadian authorities and indicted for fraud.

Psychic surgery made U.S. tabloid headlines in March 1984 when comedian Andy Kaufman, diagnosed with large cell carcinoma (a rare lung cancer), traveled to the Philippines for a six-week course of psychic surgery. Practitioner Jun Labo claimed to have removed large cancerous tumors and Kaufman declared to believe the cancer had been removed. Kaufman died from renal failure as consequence of a metastatic lung cancer, on May 16, 1984.

Brazil

The origins of the practice in Brazil are obscure; but by the late 1950s several “spiritual healers” were practicing in the country. Many of them were associated with Kardecism, a major spiritualistic movement in Brazil[, and claimed to be performing their operations merely as channels for spirits of deceased medical doctors. Others were following practices and rituals known as “Umbanda”, a shamanic ritualistic religion with mediumistic overtones inherited from the African slaves brought to the country in colonial times.

Medical and legal criticism

In 1975, the Federal Trade Commission declared that “‘psychic surgery’ “is nothing but a total hoax”.” Judge Daniel H. Hanscom, when granting the FTC an injunction against travel agencies promoting psychic surgery tours, declared: “Psychic surgery is pure and unmitigated fakery. The ‘surgical operations’ of psychic surgeons … with their bare hands are simply phony.”

In 1990, the American Cancer Society stated that it found no evidence that “psychic surgery” results in objective benefit in the treatment of any medical condition, and strongly urged individuals who are ill not to seek treatment by psychic surgery.

The British Columbia Cancer Agency “strongly urges individuals who are ill not to seek treatment by psychic surgeon.”

While not directly hazardous to the patient, the belief in the alleged benefits of psychic surgery may carry considerable risk for individuals with diagnosed medical conditions, as they may delay or forgo conventional medical help, sometimes with fatal consequences.

Accusations of fraud

According to stage magician James Randi, psychic surgery is a sleight-of-hand confidence trick. He has said that in personal observations of the procedure, and in movies showing the procedures, he can spot sleight-of-hand moves that are evident to experienced stage magicians, but might deceive a casual observer. Randi has replicated the appearance of psychic surgery himself through the use of sleight-of-hand. Professional magicians Milbourne Christopher and Robert Gurtler have also observed psychic surgeons at work, and claimed to have spotted the use of sleight-of-hand. On his A&E show Mindfreak in the episode “Sucker,” illusionist Criss Angel performed “Psychic Surgery,” showing first-hand how it may be done (fake blood, plastic bags and chicken livers were used).
