India heading for diabetes explosion
India leads the world in the looming epidemic of diabetes, the 20th annual World Diabetes Congress of the International Diabetic
Federation (IDF) was told here on Monday.

In its annual report, the IDF said India currently has the highest number of 50.8 million people suffering from diabetes, followed by China with 43.2 million and the US with 26.8 million. The report projected 58.7 million diabetes cases in India by 2010 - almost 7 per cent of its adult population.

By 2030, over 8.4 per cent of the Indian adult population will suffer from diabetes, thanks to the increasing life expectancy and urbanisation, the report said.

Warning Indian policy makers, the report said, "Evidence suggests that in more affluent parts of the country, the rural prevalence is higher than in less affluent rural areas, indicating that increasing economic growth will raise diabetes prevalence in India even more than these possibly conservative estimates have indicated."

The rampaging diabetes will impose a huge economic burden on India and other countries, it added. Apart from losing billions in lost productivity, the report said, India will also be spending $2.8 billion annually on diabetes control
measures by 2010.

There are estimated to be 285 million diabetes cases worldwide, accounting for seven per cent of the world's population.

Diabetes, along with cardiovascular disease, cancer and chronic respiratory diseases, accounts for 60 per cent ff all deaths worldwide.

"Diabetes imposes a large economic burden on the individual, national healthcare system and economy. Healthcare expenditures on diabetes are expected to account for 11.6 per cent of the total healthcare expenditure in the world in 2010," the report said.

"Estimated global healthcare expenditures to treat and prevent diabetes and its complications are expected to total at least $376 billion in 2010."

Addressing the congress, Martin Silink, outgoing president of the International Diabetic Federation, said the epidemic of diabetes will increase from 7 million new cases a year in 2007 to 10 million new cases this year.

The epidemic is getting out of control, said incoming IDF president Jean-Claude Mbanya. He said if the trend continues unchecked, there will be 435 million people with diabetes worldwide by 2030.

More than 12,000 delegates and 400 speakers from around the world are attending the congress.

Multi-vitamins could trigger health risks
Vitamin supplements do nothing to stave off illness and could even lead to cancer, a leading expert
has warned.

Professor Martin Wiseman, medical and scientific adviser for the World Cancer Research Fund, has pointed out that people who regularly take vitamin and mineral supplements instead of eating a balanced diet are at greater risk.

"Many people think they can reduce their cancer risk by taking supplements, but the evidence does not support this," the Daily Express quoted Wiseman as saying. "Just because a dietary pattern that provides a relatively high level of a particular nutrient might protect against cancer, it does not mean taking it in tablet form will have the same effect.

"In fact, at high doses the effect of these micronutrients is unpredictable and can be harmful to health,"Wiseman added. Research suggests that vitamins A and E can actually cause illness. Wiseman said: "There are studies that show high doses of some supplements can increase risk of some cancers."

Rich nations should lead in combating climate change
Beijing: India has asked developing countries to maintain steadfast unity on the issue of climate change to ensure that developed nations take due responsibility for scaling down greenhouse gas emissions.

With the world gearing up to meet for a major climate summit in Copenhagen this December, union health minister Ghulam Nabi Azad said that developing countries were not responsible for concentration of green house gases in the atmosphere and hence Western nations should take lead in combating climate change.

Azad said that the countries of the 'south', whose per capita emissions are still very low, should unite to ensure that these obligations are met by the developed countries.

"We, the countries of the south should maintain steadfast unity to ensure that these obligations are met by the developed countries," he said while addressing the 5th Asia Pacific Conference on Reproductive and Sexual Health and Rights (APCRSHR).

"The United Nations Framework Convention on Climate Change has specifically recognised that parties should take action to protect the climate system on the basis of equity and in accordance with their common but differentiated responsibilities and respective capabilities," he said.

He said that accordingly the developed country parties should take the lead in combating climate change and the adverse effects thereof.

Washing hands can save 400 children everyday
Diarrhoea kills nearly 1,000 children below the age of five everyday in India, but washing hands with soap and water can save the lives of at least 400 of these kids, a UN agency said Thursday on the occasion of Global Handwashing Day.

'In India, diarrhoea is a major killer with about 1,000 children below 5 years dying every day due to diarrhoea alone. Handwashing with soap can reduce diarrhoeal deaths in children by 40 percent and is one of the most inexpensive ways to prevent diarrhoeal disease,' the Unicef said.

The agency said that proper handling and safe storage of water reduces incidences of diarrhoea by nearly half.

'Toilet use can reduce presence of diarrhoea causing agents but toilet usage in India is still very low. In 2006, toilet usage in India was 28 percent but this is showing an upward trend because of the government of India's flagship programme - Total Sanitation Campaign. Nirmal Gram Purashkar has led to more than 18,020 Panchayats being declared free of open defecation,' Unicef said.

'Yet, despite its life-saving potential, handwashing with soap is seldom practised and is not always easy to promote,' the agency added.

The UN agency said every one can make a difference in the 'Clean hands save lives' campaign. Each year, diarrhoeal diseases and acute respiratory infections are responsible for the deaths of more than 3.5 million children under the age of five.

The second annual Global Handwashing Day, being celebrated Thursday, puts the spotlight on the importance of washing hands with soap and water as one of the most effective and affordable health interventions.

Placebo effect starts in the spine
If you thought the placebo effect was all in the mind, think again. Scientists have solved the mystery of why some people benefit from remedies that do not contain any active pain-relief ingredients.

Research suggests that placebos work, in part, by blocking pain signals in the spinal cord from arriving at the brain in the first place.

When patients expect a treatment to be effective the brain area responsible for pain control is activated, causing the release of natural endorphins.

The endorphins send a cascade of instructions down to the spinal cord to suppress incoming pain signals and patients feel better whether or not the treatment had any direct effect.

The sequence of events in the brain closely mirrors the way opioid drugs, such as morphine, work - adding weight to the view that the placebo effect is grounded in physiology.

The finding strengthens the argument that many established medical treatments derive part of their effectiveness from the patients' expectation that the drugs will make them better.

The latest studies on antidepressants suggest that at least 75 per cent of the benefit comes from the placebo effect. GPs also observe that patients report feeling better only days after being prescribed antidepressants, even though the direct effects take several weeks to kick in.

In the study, published today in the journal Science, the spinal cords of 15 healthy volunteers were scanned using functional magnetic resonance imaging (MRI). The scan homed in on an area called the dorsal horn, which transmits pain signals coming up through the spinal cord into the pain-related areas in the brain.

During the scan, the volunteers received laser "pinpricks" to their hands. The volunteers were told that a pain-relief cream had been applied to one of their hands and a control cream to the other. But unknown to the volunteers, an identical control cream was administered to both hands.

When people believed that they had received the active cream, they reported feeling 25 per cent less pain and showed significantly reduced activity in the spinal cord pathway that processes pain.

Previously, it has been shown that placebo causes the release of natural opioids in areas of the brain involved in pain control, such as the rostral anterior cingulate cortex. However, it was not known whether the natural opioids acted on the spinal cord in the same way as artificial painkillers or whether they simply changed people's tolerance or interpretation of pain.

"We've shown that psychological factors can influence pain at the earliest stage of the central nervous system, in a similar way to drugs like morphine," said Falk Eippert, of the University Medical Centre Hamburg-Eppendorf, who led the study.

Until now, the difficulty of obtaining MRI images of the spinal cord, because of its small size and its being surrounded by airways and pulsating arteries, prevented this question from being addressed. However, advances in image processing allowed the Hamburg team to obtain high resolution scans of the region.

The advance in imaging techniques is likely to have important applications for drug development.

Pharmaceutical companies are working to develop new anaesthetic drugs that target the pain pathways in the spinal cord. Being able to image this area of the body provides a direct way of testing whether the drugs are working as intended.

Swine flu may cause blood clotting in lungs: Study
A Michigan study states that all those severely down with the H1N1 influenza, swine flu, are at a higher risk of developing blood clots in their lungs.

A blood clot in lungs is usually called pulmonary [pertains to lungs and respiratory system] embolism, a condition that occurs when one or more arteries in the lungs gets blocked.

The findings of the study suggested that in the wake of H1N1 virus's potential complications, medical practitioners, especially the radiologists, will have to be more aware to look closely for the risks of pulmonary embolism in severely sick patients.

Experts say that a blood clot in lung can also cause low oxygen levels in the blood and damage vital organs in the body because of lack of oxygen. The patient can feel light headed or chest pain and can also die as a result. However, they say that blood-thinning drugs can reduce the risk of death in such conditions.

Study and its findings
Researchers based at the University of Michigan, U.S., examined the medical condition
of 66 patients diagnosed with the H1N1 swine flu. Of these, 14 patients were severely ill with the H1N1 infection. Due to their severe medical condition, they had to be admitted to the intensive-care unit.

In order to identify the risk caused by the lethal H1N1 virus, all 66 patients underwent CT [a non-invasive procedure that takes cross-sectional images of the brain or other internal organs; to detect any abnormalities that may not show up on an ordinary x-ray.] scans--medical imaging method using computer processing--to look for any complications caused by the pandemic flu.

Reports of the CT scans detected pulmonary embolisms in five of the 14 intensive-care unit patients. However, the researchers maintained that initial standard chest X-rays were normal in more than half of the patients with H1N1 infections.

"These findings indicate that imaging studies would have to be repeated in severely ill patients to monitor disease progression," said study co-author Dr. Ella Kazerooni, director of the University of Michigan's division of cardiothoracic radiology. "It's important to heighten awareness not only among the radiologists, but also among the referring clinicians."

The researchers noted that more sophisticated CT scans are needed to diagnose the potentially fatal condition since the standard chest X-rays cannot effectively scan the lungs.

A report by World Health Organisation (WHO) also warns that the H1N1 might return for a second strike in winters in a more mutated form, infecting the lungs deeper this time.

Green tea may curb risk of some cancers
Drinking green tea may lower your risk of developing certain blood cancers, but it will take about 5 cups a day, according to a study from Japan.

Drinking green tea has been associated with lower risk of dying and heart disease deaths, Dr. Toru Naganuma, at Tohoku University School of Medicine in Sendai, Japan told Reuters Health in an email correspondence.

The current study, Naganuma said, suggests drinking green tea may have a favorable effect "for particular cancers."

After gathering information on the diets and green tea drinking habits of a large group of Japanese adults aged 40 to 79 years old, Naganuma and colleagues followed the group for development of blood and "lymph system" cancers. The lymph system is a major component of the body's immune system.

The 19,749 men and 22,012 women who participated in the study had no previous history of cancer, Naganuma and colleagues note in the American Journal of Epidemiology.

During 9 years of follow up, 157 blood, bone marrow, and lymph system cancers developed in the study group.

Naganuma's team found that the overall risk for blood cancers was 42 percent lower among study participants who drank 5 or more, versus 1 or fewer, cups of green tea daily.

Drinking 5 or more cups of green tea daily was also associated with 48 percent lower risk for lymph system cancers.

These associations held up in analyses that allowed for age, gender, education, smoking status and history, alcohol use, and fish and soybean consumption.

The researchers also observed reduced risk for blood-related cancers among obese study participants, who are "considered to have higher risk of these cancers," Naganuma said.

The investigators say further studies are needed to confirm the health benefits of drinking green tea, and to determine whether daily consumption might prevent certain cancers.

UNICEF, WHO launch report on 2nd greatest killer of children
Despite the existence of inexpensive and efficient means of treatment, diarrhoea kills more children than AIDS, malaria and measles combined, according to a report issued here Wednesday by the UN Children's Fund (UNICEF) and the World Health Organization (WHO).

The report, titled "Diarrhoea: Why Children Are Still Dying and What Can Be Done," includes information on the causes of diarrhoea,data on access to means of prevention and treatment, and a seven-point plan to reduce diarrhoea deaths.

"It is a tragedy that diarrhoea, which is little more than an inconvenience in the developed world, kills an estimated 1.5 million children each year," said UNICEF Executive Director, Ann M.Veneman. "Inexpensive and effective treatments for diarrhoea exist, but in developing countries only 39 per cent of children with diarrhoea receive the recommended treatment."

Margaret Chan, Director-General of WHO, said: "We know where children are dying of diarrhoea. We know what must be done to prevent those deaths. We must work with governments and partners to put this seven-point plan into action."

Diarrhoea is a common symptom of gastrointestinal infection, which can have a variety of sources. However just a handful of organisms are responsible for most acute cases of diarrhoea and one, Rotavirus, is responsible for more than 40 per cent of all diarrhoea-related hospital admissions of children under five. A new vaccine for Rotavirus has been found to be safe and effective but is still largely unavailable in most developing countries.

Though most episodes of childhood diarrhoea are mild, acute cases can lead to significant fluid loss and dehydration. This dehydration can lead to death unless fluids are quickly replaced.

Oral rehydration therapy is the cornerstone of fluid replacement and the new low-osmolarity formula of oral rehydrationsalts (ORS) is a simple, inexpensive and life-saving remedy that prevents dehydration in children suffering diarrhoea.

Some 88 percent of diarrhoeal deaths worldwide are attributable to unsafe water, inadequate sanitation and poor hygiene. As of 2006, an estimated 2.5 billion people around the world were not using adequate sanitation facilities, and about 1 in 4 people in developing countries practised open defecation.

Access to clean water and good hygiene practices are extremely effective in preventing childhood diarrhoea. Hand washing with soap has been shown to reduce the incidence of diarrhoeal disease by over 40 percent, making it one of the most cost-effective interventions for reducing child deaths caused by this neglected killer. Thursday October 15 is annual Global Handwashing Day when millions of children and adults in over 80 countries will take part in activities to highlight this key intervention.

The overall health and nutrition of children is also critical to their susceptibility to diarrhoea and the damage it can cause. Undernourished children are at higher risk of suffering more frequent, severe and prolonged episodes of diarrhoea, and repeated bouts of diarrhoea also place children at greater risk of worsening nutritional status.

The seven point plan to save the lives of children stricken by diarrhoea includes two treatment and five prevention elements.

The two treatment elements are:

1. fluid replacement to prevent dehydration; and

2. zinc treatments, which decrease the severity and duration ofthe attack.

The five prevention elements are:

1. immunization against rotavirus and measles;

2. early and exclusive breastfeeding and vitamin A supplementation;

3. handwashing with soap;

4. improved water supply quantity and quality; and

5. promoting community-wide sanitation.

Campaigns targeting childhood diarrhoea in the 1970s and 1980s achieved success by educating caregivers and scaling up oral rehydration therapy to prevent dehydration.

The campaigns delivered promising results but following that success, focus shifted to other health problems. There is now an urgent need to shift attention and resources back to treating and preventing diarrhoea, UNICEF officials said.

Risk factors for catching cancer
Cancer used to be thought one of those diseases that you couldn't get from anyone else. If you got it, it was the fault of your genes. But as time has gone on, it has become obvious that lifestyle is at least as big a factor, and that alongside drinking, smoking and eating too much, which can all be implicated, the viruses that we pass from one to another can raise our risk.

Transmission of cancer from mother to child is incredibly rare and has now been shown to have genetic triggers. The baby's immune system should have blocked the cancer, but it did not recognise the enemy. As far as we know, there was nothing in the mother's lifestyle that made cancer more likely.

But usually cancer is a combination of genetic propensity and environmental circumstances. Risk factors for many cancers include obesity. Cervical cancer is caused by a virus - the human papillomavirus (HPV), for which we now have a vaccine. HPV is sexually transmitted. But most women come into contact with it at some point in their lives and most women clear it from their bodies without knowing it. Only in a very small proportion of cases does it cause cancer.

Viruses may well trigger other cancers. There are theories around leukaemia and childhood infections. But Mel Greaves of the Institute of Cancer Research, who led the present study, earlier showed through analysing heel-prick blood from newborns that many already have cell damage that can lead to cancer. Cancer cannot be caught like a cold. The most positive message of the new study is that it affects some people whose immune systems are not working as well as they should. That could lead to treatments to boost the immune systems of people who are known to be at genetic risk or who have already had cancer.

Exercise does make you feel sexier
Feeling lighter now that you have been gymming for a week? Convinced the pounds have started melting, improving your looks? It's all in your mind.

It's the exercise and not higher levels of fitness that is improving your body image, says a study by Heather Hausenblas, an exercise psychologist from the University of Florida, and her student Anna Campbell. After analysing 57 studies to see how physical activity impacts an individual's body image, they found even if exercise didn't improve fitness levels, it did make people feel better about themselves.

What's more, it wasn't how hard you exercises, or how much but just that you did.

One study showed no difference in body image improvement between people who exercised minimum 30 minutes a day, five days a week and those who didn't. "We would have thought that people exercising this amount would have felt better about their bodies than those who did not work out as much," Hausenblas said.

In another study, women were found to feel slightly better about their bodies than were men if they sweated it out. "We believed the gap would be much bigger, but what could be coming into play is the rise of body image issues among men. We're seeing more media portrayals of the ideal physique for men rather than the overriding emphasis on women we did in the past," Hausenblas said.

And the older you get, the better exercise impacts you psychologically perhaps because older people are more concerned about their bodies as physical activity among them is lower than younger people.

Low body image is becoming something of an epidemic across the world due to unrealistic images being flashed in the media. "Body dissatisfaction is a huge problem in our society and is related to all sorts of negative behaviour including yo-yo dieting, smoking, taking steroids and undergoing cosmetic surgery. It affects men and women and all ages, starting with kids who are as young as five years old saying they don't like how their bodies look," said Hausenblas. The analysis has been detailed in Journal of Health Psychology.

If you don't like what you see in the mirror, time to switch to the mirror in the gym. Mind matters.
