Broccoli compound may combat COPD

In chronic obstructive pulmonary disease (COPD), damage to immune cells limits the lungs’ ability to fight off bacterial infections. According to a new study, boosting the activity of a specific molecule in these cells can restore their defensive powers. In patients with COPD, immune cells called macrophages lose their ability to engulf and remove bacteria, making the lungs more vulnerable to infection. Until now, no one knew how to reverse this damage to the macrophages.

A team of scientists at Johns Hopkins University, led by Drs. Shyam Biswal and Robert Wise, investigated why macrophages don’t work properly in COPD patients. Previous research suggested that a process called oxidative stress might be to blame. Oxidative stress occurs when the body can’t effectively neutralize damaging compounds called peroxides and free radicals.

A molecule called Nrf2 can cause cells to make more antioxidants, which neutralize these harmful compounds. Previous studies found reduced Nrf2 activity in severe COPD. The scientists suspected that increasing Nrf2 activity might restore the ability of macrophages to remove bacteria. To test their theory, the team used a chemical called sulforaphane, which is known to activate Nrf2. A precursor of sulforaphane is found in broccoli. The research was cosponsored by NIH’s National Heart, Lung and Blood Institute (NHLBI) and National Institute of Environmental Health Sciences (NIEHS). The results appeared in the April 13, 2011, issue of Science Translational Medicine.

The researchers first took macrophages from the lungs of patients with moderate COPD. When they treated these macrophages with sulforaphane, they saw higher Nrf2 levels in the cells. Sulforaphane treatment also boosted the ability of cultured macrophages to clear 2 of the major types of bacteria that infect COPD patients. Macrophage uptake of bacteria rose 300% after treatment, whether the cells came from smokers or non–smokers. Experiments in mouse and human cells revealed that sulforaphane, through Nrf2, increases levels of a receptor called MARCO on macrophages. MARCO activity was necessary for macrophages to engulf bacteria after sulforaphane treatment. Mice exposed to smoke had lower levels of MARCO. Furthermore, smoke-exposed mice genetically engineered to lack Nrf2 had more lung inflammation and higher levels of bacteria.

The team gave sulforaphane with a nebulizer to mice exposed to smoke and found that the mice’s lungs showed reduced inflammation and bacterial burden. The researchers also gave human COPD patients broccoli sprout extract enriched with sulforaphane for 2 weeks. The patients taking the extract had higher levels of MARCO and Nrf2–controlled antioxidants in their blood cells. A NHLBI–sponsored clinical trial is now being conducted to test if sulforaphane can provide relief to patients with COPD. (Source NIH)

Timing of treatment for relapsed ovarian cancer

For most women, second–line treatment for relapsed ovarian cancer be initiated at the time when signs or symptoms of a disease recurrence are detected, rather than on the basis of an asymptomatic elevation in the CA–125 level. However, this decision should be individualized and based upon an active discussion between physicians and patients of the risks and benefits of early versus delayed treatment. (October 8, 2010)

Chemical Castration
Dr. Anil Goyal, Sr. Consultant Urologist

Chemical castration is the administration of medication designed to reduce libido and sexual activity, usually in the hope of preventing rapists, child molesters and other sex offenders from repeating their crimes. Unlike surgical castration, where the testes or ovaries are removed through an incision in the body, chemical castration does not actually castrate the person, nor is it a form of sterilization. For this reason, the term "chemical castration" has been called a misnomer. Chemical castration is generally considered reversible when treatment is discontinued, although permanent effects in body chemistry can sometimes be seen, as in the case of bone density loss increasing with length of use of Depot medroxyprogesterone acetate (DMPA). Castration has, from time to time, been used as an instrument of public and/or judicial policy despite concerns over human rights and possible side effects.

Application: Chemical castration involves the administration of anti-androgen drugs, such as cyproterone or the birth-control drug DMPA, which is given as an injection every three months, making compliance easier to track.

Effects: When used on men, these drugs can reduce sex drive, compulsive sexual fantasies, and capacity for sexual arousal. Life-threatening side effects are rare, but some users show increases in body fat and reduced bone density, which increase long-term risk of cardiovascular disease and osteoporosis. They may also experience other "feminizing" effects such as gynecomastia, reduced body hair, and loss of muscle mass.

Ethical objections: Although some people consider chemical castration as a humane alternative to life-long imprisonment or surgical castration, the American Civil Liberties Union opposes the coerced administration of any drug, including antiandrogen drugs for sex offenders. They argue that forced chemical castration is a "cruel and unusual punishment", and therefore should be constitutionally prohibited by the Eighth Amendment. They also stated that it interfered with the right to procreate, and could expose users to various health problems. It has also been argued that, based on the Fourteenth Amendment, the procedure fails to guarantee equal protection - although the laws mandating the treatment do so without respect to gender, the actual effect of the procedure falls disproportionately upon men. In the case of voluntary statutes, the ability to give informed consent is also an issue: in 1984, the US state of Michigan's Court of Appeals held that mandating chemical castration as a condition of probation was unlawful, on the grounds that the drug medroxyprogesterone acetate had not yet gained acceptance as being safe and reliable and also due to the difficulty of obtaining informed consent under these circumstances.

Studies: In 1981, in an experiment by P. Gagne, 48 males with long standing histories of sexually deviant behavior were given medroxyprogesterone acetate for as long as 12 months. Forty of those subjects were recorded as to have diminished desires for deviant sexual behaviour, less frequent sexual fantasies, and greater control over sexual urges. The research recorded a continuation of this more positive behaviour after the administration of the drug had ended, with no evidence of adverse side effects, and recommended medroxyprogesterone acetate along with counselling as a successful method of treatment for serial sex offenders.

History and use by country: The first use of chemical castration occurred in 1944, when diethylstilbestrol was used with the purpose of lowering men's testosterone.

United States: In 1966, John Money prescribed medroxyprogesterone acetate (MPA, the base ingredient now used in Depo Provera) as a treatment for a patient dealing with pedophilic urges, becoming the first American to employ chemical castration. Since then, the drug has become a mainstay of chemical castration in America. Despite its long history and established use, the drug has never been approved by the FDA for use as a treatment for sexual offenders. California was the first U.S. state to specify the use of chemical castration as a punishment for child molestation, following the passage of a modification to Section 645 of the California penal code in 1996. This law stipulates that anyone convicted of child molestation with a minor under 13 years of age may be treated with Depo Provera if they are on parole if it is their second offense and offenders may not reject the treatment.

The passage of this law led to similar laws in other states, such as Florida's Statute Section 794.0235 which was passed into law in 1997. As in California, treatment is mandatory after a second offense.
Besides California and Florida, at least seven other states, including Georgia, Iowa, Louisiana, Montana, Oregon, Texas and Wisconsin, have experimented with chemical castration. In Iowa, as in California and Florida, offenders may be sentenced to chemical castration in all cases involving serious sex offenses. On June 25, 2008 Louisiana Governor Bobby Jindal signed Senate Bill 144, allowing Louisiana judges to sentence convicted rapists to chemical castration.

Europe: The drug cyproterone acetate has been commonly used for chemical castration throughout Europe. It is similar to the drug MPA used in America. In the United Kingdom, computer scientist Alan Turing, famous for his contributions to mathematics and computer science, was a homosexual who chose to undergo chemical castration in order to avoid imprisonment in 1952. At the time, homosexuality was still illegal and considered to be a mental illness that could be treated with chemical castration. Turing experienced side effects such as breast enlargement and bloating of the physique. Two years later, he committed suicide. In 2009, the British Prime Minister, Gordon Brown, issued a public apology for the British government's "appalling" actions after an online petition seeking the same gained 30,000 signatures and international recognition. In the 1960s, German physicians used antiandrogens as a treatment for sexual paraphilia.

On September 25, 2009 Poland passed legislation for forcible chemical castration of child molesters. This law came into effect on June 9, 2010 so in Poland "anyone guilty of raping a child under the age of 15 can now be forced to submit to chemical and psychological therapy to reduce sex drive at the end of a prison term". On April 30, 2010 a man in the United Kingdom found guilty of attempting to murder a 60-year-old woman in order to abduct and rape her two granddaughters, agreed to undergo chemical castration as part of the terms of his sentence. On March 4th, 2011 a 66-year-old man in Germany was found guilty of molesting 400 children while he knew he had AIDS. He got a 9 year prison penalty and chemical castration is a part of his sentence.

Israel: In May 2009, two brothers from Haifa, convicted child molesters, agreed to undergo chemical castration to avoid committing further crimes.

Argentina: In March 2010, Mendoza, a province in Argentina, approved a new law which rules the use of chemical castration for rapists, but they must voluntarily undergo it.

NIF launches biscuits using traditional recipe

AHMEDABAD: In what would come as a boon to people who observe religious fasting, National Innovation Foundation (NIF) along with the Future Group launched a range of nutritional biscuits based on traditional recipes on Wednesday. The biscuits are made from natural ingredients such as arrowroot (shingora) and buckwheat (kuttu) which are eaten in fasts, kodra millet, corn and different varieties of grains which are traditionally known to have medicinal and other beneficial properties. While NIF scouted the knowledge of these traditional recipes from villages in the state, the royalty will benefit the communities that grow these varieties of crops. Talking about how the rural communities will benefit from this initiative executive vice chairperson at NIF, Anil Gupta said, "It is a knowledge that belongs to the community which grows the crop. These crops are grown in more than one village in the state and the royalty from the product will benefit the communities which will lead to the future growth." (Source; TOI, Apr 28, 2011)

To defund or not to defund?

The U.S. House will vote on whether to defund the Prevention and Public Health Fund created under the health care reform bill last year. The $15 billion dollar fund was designed to enable state and local governments, community organizations and nonprofits to create physical activity programs at the community level, incentivize workplace wellness and increase healthy food options in schools. The Fund has been subject to a flurry of back and forth among lawmakers over the past several months on whether to cut it or keep it. Last week, the Energy and Commerce Committee voted in favor of repeal. It now goes to the House Floor for a full vote.

Biomarker predicts colon cancer survival in obese patients

A protein biomarker may predict better chances of survival for obese patients with colorectal cancer, but the biomarker held no prognostic value for nonobese patients, researchers found (April 27 issue of the Journal of the American Medical Association). Patients with a body mass index of 30 kg/m2 or more were 76% less likely to die from colorectal cancer when positive for cadherin–associated protein beta–1 (CTNNB1 or beta–catenin, P<0.001 for interaction) in analysis of nearly 1,000 prospectively–followed patients.

Stress fracture risk higher for girls who run and jump

High–impact physical activity increases the risk of stress fractures for adolescent girls, researchers reported. In a large prospective study that followed nearly 7,000 girls for seven years, the increase in risk was driven by running, playing basketball, and taking part in cheerleading or gymnastics, according to Alison Field, ScD, of Harvard Medical School, and colleagues. On the other hand, there was no link between stress fractures and such low–and moderate–impact activities as swimming, skating, aerobics, and karate, Field and colleagues reported online in Archives of Pediatrics & Adolescent Medicine.

    An Inspirational Story

(Dr Prachi Garg)

The obstacle in our path

In ancient times, a king had a boulder placed on a roadway. Then he hid himself and watched to see if anyone would remove the huge rock. Some of the king’s wealthiest merchants and courtiers came by and simply walked around it. Many loudly blamed the king for not keeping the roads clear, but none did anything about getting the big stone out of the way. Then a peasant came along carrying a load of vegetables. On approaching the boulder, the peasant laid down his burden and tried to move the stone to the side of the road. After much pushing and straining, he finally succeeded. As the peasant picked up his load of vegetables, he noticed a purse lying in the road where the boulder had been. The purse contained many gold coins and a note from the king indicating that the gold was for the person who removed the boulder from the roadway. The peasant learned what many others never understand. Every obstacle presents an opportunity to improve one’s condition.

The Mental Capacity Act, 2005 United Kingdom-Aruna case

Provision relating to persons who lack capacity and to determine what is in their best interests and the power to make declaration by a special Court of Protection as to the lawfulness of any act done in relation to a patient

  • The withdrawal of nutrition by stopping essential food by means of nasogastric tube is not the same as unplugging a ventilator which artificially breathes air into the lungs of a patient incapable of breathing resulting in instant death. In case of discontinuance of artificial feeding, the patient will as a result starve to death with all the sufferings and pain and distress associated with such starving. This is a very relevant consideration in a PVS patient like Aruna who is not totally unconscious and has sensory conditions of pain etc. unlike Antony Bland in Airedale vs. Director MHD (1993) 2 WLR 316 who was totally unconscious. Would the doctor be able to avoid such pain or distress by use of sedatives etc.? In such a condition would it not be more appropriate to continue with the nasogastric feeding but not take any other active steps to combat any other illness which she may contract and which may lead to her death?
  • 34. Mr. Andhyarujina further submitted that in a situation like that of Aruna, it is also necessary to recognize the deep agony of nurses of the hospital who have with deep care looked after her for over 37 years and who may not appreciate the withdrawal of the life support. It may be necessary that their views should be considered by the Court in some appropriate way.

    Rabies Update

Dr A K Gupta, Author of "RABIES – the worst death"

What should be done with severe animal bite wounds that would, with most other types of injury, be closed by primary suture?

If possible, avoid suturing of the bite wound as it may risk inoculation of the virus deep into the wound. However, if the wound has to be sutured, it should be done after infiltration of RIGs into and around wounds. Any surgical manipulations of possibly rabies-infected animal bite wounds increase the risk of death.

Can modern vaccines be diluted with tetanus toxoid or water or any other diluents and injected?

Diabesity A deadly new cocktail of sugar and fat

Under the new International Diabetes Federation (IDF) guidelines, patients with type 2 diabetes warrant bariatric surgery when their body mass index is 35 kg/m2 or higher, or when it is between 30 and 35 kg/m2 and their diabetes cannot be controlled by medicine and lifestyle changes. This latter indication is even stronger when there are other major cardiovascular risk factors, including hypertension, hyperlipidemia, and a history of heart attacks, said Dr. Rubino, chief of the Gastrointestinal Metabolic Surgery Program at New York–Presbyterian Hospital/Weill Cornell Medical Center. The body mass index action points can be reduced by 2.5 kg/m2 for Asians. The guidelines were drawn up by an IDF taskforce of diabetologists, endocrinologists, surgeons, and public health experts who met in December 2010.

The use of bariatric surgery to treat diabetes has sparked controversy in healthcare circles. Critics question the wisdom of wielding a scalpel to solve a medical problem, especially when clinicians have more drugs at their disposal to deal with diabetes. The IDF taskforce calls for randomized controlled trials to compare different bariatric procedures for diabetes between themselves, "as well as emerging non–surgical therapies."

  1. Dear Dr Aggarwal, I appreciate the interest you have in Sanskrit and the detailed notes on different samadhis. Your spirituality is quite amazing. Regarding Dr Bhatnagar’s conflict of not ending the lady’s life as per her wish I think he is justified in practising euthanasia. Each of us has our own moral responsibility to the society and God. No legislation would mitigate the sufferings of millions of poor Indians spending their lives in a vegetative condition for years. I may sound like a rebel but we are scientists. Euthanasia cannot be legalized but practised by individual doctors on the merit of the case. Dr. R Mani, Psychiatrist.
  2. Hello Sir, If a government hospital provides a separate sitting/personal room to one physiotherapist with a name plate hanging on the door Dr. -XYZ & provides additional area for physiotherapy procedures and does not provide a room to any medical officer. Then is this wrong or not? How can a paramedic use a nameplate bearing the sign ‘Doctor’ in a government hospital? Why he/she is given a separate personal room when doctors are not given any room? What action can a doctor take against this? If government has decided to allow physiotherapists to be considered as Doctors then why not Nurses too? They are more clinical then physiotherapist. Some physiotherapist even prescribing drugs to the patients in government hospital. Some even say that they do better job then orthopedicians. What is this sir? What can be done? Please reply. Dr Lalit Tanwar.

Women who eat lot of meat prone to weight gain

Women who eat a lot of meat are apt to weigh more than those who do not, said Padma Shri & Dr. B.C. Roy National Awardee Dr. KK Aggarwal, President, Heart Care Foundation of India.

Previous studies have consistently shown that vegetarians are lighter and have a lower body mass index than their omnivorous counterparts.

Dr. Garrett Hoy and co-investigator Larry A. Tucker evaluated 284 premenopausal women, aged an average of 40 years old and did not smoke. The researchers separated the women into groups classified by low, moderate, and high meat intake per 1,000 calories consumed per day.

Over the 7-day study, the investigators found that the low-intake group ate less than 1.9 three-ounce servings of meat per day, as opposed to more than 3.18 servings for the high-intake group.

More than half (52.8 percent) of the women classified as having a high meat intake were obese, defined in this study as having greater than 35 percent body fat. Conversely, 37.3 percent of women in the moderate meat intake group were obese and only 15.6 percent of those in the low meat intake group were obese.

"This was a cross-sectional study, so our findings do not show that meat causes obesity. While that could be the case, it could also be that obesity caused women to eat more meat -- like more obese women following the Atkins diet," which is rich in meat,” Hoyt said.

There are a number of physiological mechanisms by which meat could fuel weight gain. Meat proteins, may elevate insulin levels, and thereby growth factors, that could influence weight and percent body fat. It has also been shown that consumption of saturated fat - most of which comes from animal products - is associated with obesity.

It may be worth recognizing that eating less meat may be beneficial in a weight management program. It is possible to eat a healthy diet that is limited in meat. Alternative protein sources such as lentils, nuts and legumes can provide sufficient protein and actually be beneficial in dieting.
