Research explains how we live in harmony with friendly gut bacteria


By Bill Hathaway; Stability in the composition of the hundred trillion bacterial cells in the human gastrointestinal tract is crucial to health, but scientists have been perplexed how our microbiota withstands an onslaught of toxins, dietary changes, and immune response to infections or antibiotics with little change.

Research from Yale published in the Jan. 9 issue of the journal Science identifies a strategy that commensal, or non-harmful, gut bacteria employ to preserve this stable relationship with their host during inflammation.

“It has been a puzzle that many immune responses target all bacteria,” said Andrew Goodman, assistant professor of microbial pathogenesis and a member of the Microbial Sciences Institute at Yale’s West Campus. “Yet healthy individuals maintain the same beneficial microbes for decades even when exposed to a host of environmental disturbances.’’

Research has shown that disruptions in the gut microbiome can lead to severe health consequences, including obesity, recurrent infections, and diseases such as irritable bowel syndrome. Instability in the microbiome has been linked to diseases as diverse as autism and cancer. Doctors may one day be able to manipulate the microbiome to treat patients, but scientists first need to understand the molecular machinery of the vast gut microbiome, which contains a hundred times more genes than the human genome.

The new study represents a first step, Goodman said. The Yale team found that in mice and humans, microbiome stability is maintained by a single gene that allows bacteria to resist high levels of inflammation-associated antimicrobial peptides. Commensal bacteria that lack this mechanism were promptly removed from the gut during inflammation in mice.

“We were surprised that a single factor could have such a large effect,” Goodman said. “This study opens the door for new approaches to understand how commensal bacteria interact with their hosts.”

Thomas W. Cullen of Yale is the lead author of the study.

Primary funding for the work was provided by the National Institutes of Health.

CHAWL-INSPIRED - Centre to provide houses on rent to migrant workers
New Delhi:


Local authorities providing rental housing facilities to migrant workforce and employees will be one of the main focus areas under the government's ambitious scheme to provide `Housing for All' in urban areas. The flagship scheme is likely to be cleared by the Cabinet this week, which also envisages building at least two crore affordable houses for the poor in cities and towns with an investment of Rs 13 lakh crore by 2022.Though this won't be modelled exactly on the lines of “chawls“ in Mumbai, government sources said the inspiration for this scheme has come from chawls, which were constructed in abundance in the early 1900s to house the people migrating to Mumbai because of its booming cotton mills and overall strong economy .
Sources said the scheme got a go ahead from the expenditure finance committee last week. “The rental housing scheme would be run by the local authorities, including municipal bodies. There can be individual flats for families and dormitories-like facilities for others. Such accommodation would be provided for a limited period, say two-three years,“ said an official.
The official said the scheme will be beneficial for those whose monthly earning is in the Rs 15,000 and Rs 20,000 bracket and can't buy flats in urban areas. “While Centre will provide some funding for this scheme, one section of investment would come from allocation of corporates under their corporate social responsibility. Base survey would be conducted in cities to identify the requirement and how such accommodation facilities can be provided expeditiously . We are not setting any targets,“ another housing ministry official said.
Another big component of the `Housing for All' scheme is to construct at least two crore affordable housing in urban areas.

SC notice on moral science in schools
New Delhi:
TIMES NEWS NETWORK


The Supreme Court on Monday issued notice to the Centre and CBSE on a PIL seeking its direction to include moral science as a compulsory subject in the school curriculum.A bench headed by CJI H L Dattu sought a response from the government on the issue raised by a practising advocate, Santosh Singh, who said that moral science must be taught at schools to inculcate values in students. “The state is under a constitutional obligation to endeavour to provide educational facilities which inculcate moral values from primary education to secondary education. But the state has failed in this primary and vital task of making students good human beings and (in) turn good citizens,“ she said in her petition.
She said that its non-inclusion as a compulsory subject in the school curriculum violates the very spirit of Article 25 of the Constitution.

Ahimsa-loving Jain doctors promote ‘veg’ medicines


Doctors following Jain religion have come together to promote ‘vegetarian’ medicines. From suggesting alternatives to gelatine-coated capsules, and promoting milk-derived calcium, these doctors are going an extra mile to stick to their religious teachings that call for ahimsa or noninjury.“People who follow our religion, or ahimsa in general, often don’t know that capsules are made of gelatin that is derived out of intestinal fibres of mammals sourced from slaughter houses. Majority of calcium tablets contain calcium derived out of oysters. There is no reason why one should be forced with medicines containing animal products if the alternatives are available,” said paediatrician Dr Bharat Parmar, the president of the Jain Doctors Federation (JDF).
The group is promoting the concept of ‘Ahimsak Chikitsa’ by spreading awareness about medicines containing animal products.
“The medicine packaging does not mention the use of animal products. Thus, most doctors, including Jains, are unaware about this. We are popularising the concept through group chats, online forums, conferences and seminars,“ said Parmar, adding that all medicines in capsule form are also available in tablet form.
“Doctors deal with lives and we don’t want the concept to come in between life-saving measures. But we are asking our doctors to use alternatives as far as possible,” said Parmar, adding that JDF has 15,000 doctors as members in India and more than 2,000 in Mumbai.
For example, all hormonal medicines are now made with synthetic sources but a particular hormone, which is a widely-used blood thinner, is still derived from animals. “We cannot ask anyone not to prescribe this medicine,” said Parmar.
“If the doctors can, they should tell the patient about animal products in the prescribed medicine. Also, since the information is not available handy, we are encouraging doctors to search about raw materials used in the medicines, so that there is increased awareness,” said Dr Mangal Jain, associate professor, department of phar macology, Grant Medical College.
He added that medical practitioners need to study the preparation in detail, including the drugs’ principal ingredients and additives.
Jain said drug manufacturers, too, should provide detailed information about their products, including raw material and its source. He said besides gelatine and glycerine used for binding, tallow used for shining, cochineal used for colouring and several flavour enhancers used in medicines contain animal products.
Meanwhile, vice-president of the Indian Pharmaceutical Association, Manjiri Gharat, said it is very unlikely for doctors to think on these lines.
“But it is true that all drugs available in capsule forms are made in tablet form too. There are a few exceptions, wherein the drugs are oil based and a capsule shell becomes a must,” said Gharat, adding there may be price variations, too, depending on the drugs.

Obesity could lead to cancer, finds study


Indians At Risk; Docs Advise Dietary Changes To Reduce Threat
Nearly everyone knows that obesity is a major cause of cardiovascular problems and diabetes. But what many do not know is that extra kilos can also lead to that emperor of maladies -cancer.Obesity is now pandemic and researchers have noted a statistically increased risk of developing cancers, especially that of the breast, endometrium, colon and rectum, among overweight people. Several studies including one by National Cancer Institute, USA, indicate that there is a direct link between obesity and cancer. Doctors who conducted these studies say unless obese individuals make appropriate dietary changes, obesity could soon overtake tobacco as the top cause of cancer.
The Overseas Development Institute, an independent think tank, found that Indians constitute a huge chunk of the one in three adults who are obese, a total of up to 1.46 billion across the world. Simultaneously ,a 16-year-long study published in the New England Journal of Medicine, which followed 90,000 American adults, revealed that the heaviest participants were more likely to develop and die from cancer than participants with healthy weight.
“Though there are no Indian studies on the subject, research done abroad is relevant to us as well as we are increasingly aping the West in terms of diet. The number of obese people in India has increased exponentially ,“ Rigid Lifeline Hospitals surgical gastroenterologist Dr J S Rajkumar said.
The surgeon recently submitted a paper to the Journal of Obesity and Metabolic Research exposing the link between cancer and obesity . He said though the answer to how obesity causes cancer may be different for each type of cancer, the overall explanation is that obesity triggers changes in bodily functions, which can lead to harmful cell growth and cell division.
Explaining the link, senior diabetologist Dr A Ramakrishnan said the link between obesity and cancer is insulin resistance.“Both obesity and cancer result from body losing its ability to burn fat as fuel. Obesity is linked to excess levels of insulin circulating in blood and this can stimulate harmful cell proliferation. It also increases oxidative stress levels in overweight people, increasing risk of cancer,“ he said.
Stressing on the link between obesity and breast, colon and endometrial cancer, oncologist Dr Deb Narayan Dutta of Apollo Hospitals said excess fat cells, when partially metabolised, become carcinogenic.
“In women, obesity exposes them to higher estrogen levels because estrogen is produced in fat tissue. Obese women therefore have more estrogen, which can lead to insulin resistance and the development of more fat tissue, which produces even more estrogen, making it a vicious cycle that raises the risk of estrogen-sensitive cancers,“ he said.
Dr Rajkumar said overweight people can significantly reduce the risk of developing cancer through behavioural, pharmaceutical and surgical strategies.
