Many Older Americans Feel Prepared for Aging
from Tumblr http://bit.ly/1SqoeB5
Why are men, in their early 30s, losing hair?
Doctors say that the major reasons for hair loss are iron deficiency, lack of sunlight (vitamin D-3), stress, irregular diets, hormonal changes and related diseases like thyroid and diabetes.
After a particularly hectic Saturday morning when Dr Narendra Patwardhan checked as many as 11 patients with hair loss, he simply deferred the remaining appointments and wished he could take on a more challenging case. The number of patients with hair loss has increased over the years and out of 10 new patients at least eight are men. What is disturbing is that a sizeable number of them are in their 20s and 30s seeking hair restoration surgery, says the president of the Association of Hair Restoration Surgeons of India.

Telogen Effluvium – a typical hair loss condition among youngsters is characterised by diffused hair shedding. It is a reactive process caused by a metabolic condition or hormonal stress or by medications. Generally, the recovery is spontaneous, occuring within six months. However, the vast majority of hair loss cases fall into the male (androgenetic) or female (pseudoandrogenetic) pattern baldness. This is caused by the effect of the hormone that leads to gradual and progressive hair loss. While medication like minoxidil does help, hair transplants or hair restoration surgeries are now the norm.
With 60-70 patients being examined for hair loss on a daily basis, Patwardhan says the major reasons are iron deficiency, lack of sunlight (vitamin D-3), stress, irregular diets, hormonal changes and related diseases like thyroid and diabetes. There has been a rise in the number of young men with hair loss. They are mainly from the IT sector. Out of 100 patients, at least 30 are from this group and the ages vary from 25 to 35 years. I have had frantic parents calling me several times to provide some solution, he adds.
In a month I do take on six-eight patients for hair restoration surgery but this is a tedious method and, like pregnancy, patients need to wait for the hair to grow, he explained. The surgery process could take around six hours under local anaesthesia for the follicular unit transplant (FUT). A small strip of hair bearing scalp is removed from the back and side of the head and these hair usually grow throughout a lifetime.
The donor region is stitched in such a way that a narrow scar is produced but is hidden by overlying hair. Special instruments are used to make small slits in the bald area and the grafts are then inserted. The growth of the transplanted hair starts in about six weeks and continues for nine months to a year.
Another technique, the follicular unit extraction (FUE), too, is fast evolving and is being adopted quite regularly. In this, a small round punch is used to extract follicular units from a patient’s bald resistant donor areas one at a time. These 1, 2, 3 and 4 groupings (called follicular unit grafts) are then transplanted into a patient’s balding areas. It may cost Rs 80/100 per graft in the FUE technique method while the Strip (FUT) method may cost Rs 80,000 onwards.
It is normal to lose 50-100 strands in a day. But the patient may have lost at least 30-60,000 hair by the time they require a hair transplant, says Dr Rajesh Rajput, founder president of the Association of Hair Restoration Surgeons of India and who has performed more than 5,000 hair transplants in the last 20 years.
Dr Rajput has, however, also done a study which shows cyclical medicine helped in improving hair count and hair calibre and in which control of hair loss was better. Promoting hair growth requires supplementation of certain minerals, vitamins, amino acids, and antioxidants, as well as control of sebum secretion and anti-dandruff treatment. However, there are drawbacks to using vitamins, minerals, and amino acids together. Excess of vitamin A and E lead to improper keratinization of hair and cause hair loss. Absorption of minerals and vitamins is dependent on their relative deficiency in the body; iron and calcium given together reduce the absorption of one another, he explained.
In a study of 500 patients, Dr Rajput combined the use of antioxidants, iron, calcium, zinc, amino acids and Vitamins E, D and C with minoxidil and finasteride to control hair loss, reverse miniaturization and achieve new hair growth within two to four months. The study was published in Hair Transplant International Forum and showed the combination treatment of drugs worked. The patients were followed up for two years and there was a definite improvement, he said.
Everyone wants to look good and advertisements promising that crowning glory and increased confidence at work lure several potential customers. This has also led to several mushrooming hair transplant clinics. There is simply no data and no checks on this, says Patwardhan who admits that the association receives complaints about non allopathic doctors who have been performing these surgeries. ens

Rigorous exercise may cut arthritis risk
Patients with arthritis often have reduced endurance and are at an increased risk of cardiovascular disease. (Source: Thinkstock Images)
High-intensity exercise may help ease symptoms of arthritis, a chronic disease that causes inflammation in the joints, says a new study.
Patients with arthritis often have reduced endurance and are at an increased risk of cardiovascular disease.
“This is why it is especially important for arthritis patients to keep fit and work on their cardiovascular endurance,” said one of the researchers Anja Bye from the Norwegian University of Science and Technology.
The study involved 18 women between the ages of 20-49.
Twenty sessions of hard training on a spinning bike was conducted for ten weeks.
The results showed a tendency to have less inflammation and the participants also experienced significant increase in maximum oxygen intake, meaning that they reduced their risk of cardiovascular disease.
The participants saw a small reduction in body mass index as well as an increase in muscle mass as a result of the training.
The study was published in European Journal of Applied Physiology.
Arthritis affects about one percent of the population, and about three times as many women as men. Mostly adults are affected, but the disease can occur in children as well.

New anti-obesity drug could block fat absorption
Researchers have developed a new class of compounds that could prevent fat particles from getting absorbed in the body and thus potentially reduce weight gain.
Researchers have developed a new class of compounds that could prevent fat particles from getting absorbed in the body and thus potentially reduce weight gain.
In tests, mice administered these compounds called “micelle sequestrant polymers”, or MSPs, had nine to 10 times the amount of triglycerides — the main dietary fat — in their faeces than the control animals.
Additionally, because the MSPs pass through the body unabsorbed, the researchers said these compounds could provide a safe approach for long-term treatment.
“MSPs may serve as a novel approach to weight loss that inhibits excess caloric intake by preventing absorption of excess dietary triglycerides,” the study said.
Currently available drugs to fight obesity can have serious side effects, including increased risk of cardiovascular disease and depression.
So Cory Berkland from the University of Kansas in the US, and colleagues set out to find new kinds of pharmaceuticals to fight weight gain.
Targeting the body’s process of absorbing fat, the researchers designed a class of polymers that capture fat particles called micelles in the intestines so they can not be digested.
Instead, they pass through the gut and are excreted.
The findings appeared in the journal Biomacromolecules.

Get up for your heart health and move for your waistline
An extra two hours per day spent walking rather than sitting is associated with approximately 2 percent lower average fasting blood sugar levels and 11 percent lower average triglycerides. (Source: Thinkstock Images)
Regular walking and running not only improve your heart but also enable you shed extra kilos around your waistline resulting in a healthy body mass index (BMI), researchers say.
“We found that time spent walking rather than sitting was significantly associated with lower levels of blood sugar and blood fats,” said Dr Genevieve Healy, senior research fellow at the University of Queensland.
Replacing sitting time with stepping out was also associated with a significant reduction in waistline and BMI.
For the study, the researchers gave activity monitors to 782 men and women aged 36-80 years.
The monitors were capable of determining how long each participant spent sleeping, sitting or lying down, standing and stepping (which includes walking and running).
An extra two hours per day spent walking rather than sitting was associated with approximately 2 percent lower average fasting blood sugar levels and 11 percent lower average triglycerides (fats in the blood).
Extra standing time was also associated with higher average levels of the “good” HDL cholesterol.
Replacing two hours a day of sitting time with stepping was associated with an approximately 11 percent lower average BMI and a 7.5cm smaller average waist circumference.
“In addition, average blood sugar levels fell by approximately 11 percent and average triglycerides by 14 percent for every two hours spent walking rather than sitting,” the authors noted.
“The finding provide important preliminary evidence that strategies to increase the amount of time spent standing or walking rather than sitting may benefit the heart and metabolism of many people,” Dr Healy explained.
“Get up for your heart health and move for your waistline,” he advised in a paper appeared in the European Heart Journal.

New blood cancer drug enters phase II clinical trials
Promising to eliminate blood cancer in its first human tria by a drug is now in phase II clinical trials, a new study says. (Source: Thinkstock Images)
A new drug found promising for treating blood cancer in its first human trial is now in phase II clinical trials, a new study says.
The drug coaxes dormant cancer stem cells, residing in the bone marrow, to begin differentiating and exit into the blood stream where they can be destroyed by chemotherapy agents.
“This drug gets that unwanted house guests to leave and never come back,” said the study’s senior author Catriona Jamieson, associate professor of medicine at University of California, San Diego School of Medicine in the US.
“It is a significant step forward in treating people with refractory or resistant myeloid leukemia, myelodysplastic syndrome and myelofibrosis,” Jamieson said.
“It is a bonus that the drug can be administered as easily as an aspirin, in a single, daily oral tablet,” Jamieson noted.
For the first-in-human study conducted between 2010-2012, the drug called PF-04449913 was tested in 47 adults with blood and marrow cancer.
They received escalating daily doses of the drug in 28-day cycles.
Treatment cycles were repeated until a participant experienced unacceptable adverse effects without evidence of clinical improvement.
The drug elicited clinical activity sufficient to establish proof-of-concept for the treatment in 23 individuals, or nearly half the study participants.
Given the promising results, the drug’s efficacy as a treatment for different types of blood cancer is now being investigated in five phase II clinical trials.
“Our hope is that this drug will enable more effective treatment to begin earlier and that with earlier intervention, we can alter the course of disease and remove the need for, or improve the chances of success with, bone marrow transplantation,” Jamieson said.
The study was published online in the journal The Lancet Haematology.

Gut bacteria can trigger depression
Bacteria has a crucial role in resulting anxiety and depression including abnormal behavior. (Source: Thinkstock Images)
Intestinal bacteria plays a key role in inducing anxiety and depression that can lead to early life stress, scientists from McMaster University in Canada have discovered.
“We have shown for the first time in a mouse model of anxiety and depression that bacteria play a crucial role in inducing this abnormal behaviour,” said Premysl Bercik, associate professor of medicine with McMaster University’s Michael G. DeGroote School of Medicine.
“It is not only bacteria but the altered bi-directional communication between the stressed host — mice subjected to early life stress — and its microbiota, that leads to anxiety and depression,” he explained.
In this study, researchers subjected mice to early life stress. Newborn mice were separated for three hours each day from their mothers and then put back with them.
Mice with complex microbiota, which had been maternally separated, displayed anxiety and depression-like behaviour, with abnormal levels of the stress hormone corticosterone.
These mice also showed gut dysfunction based on the release of a major neurotransmitter called acetylcholine.
Then, they repeated the same experiment in germ-free conditions and found that in the absence of bacteria, mice which were maternally separated still have altered stress hormone levels and gut dysfunction.
“Neonatal stress leads to increased stress reactivity and gut dysfunction that changes the gut microbiota which, in turn, alters brain function,” Bercik noted in a paper published in the journal Nature Communications.
The data show that relatively minor changes in microbiota profiles or its metabolic activity induced by neonatal stress can have profound effects on host behaviour in adulthood.

Healthy dose of adventure can ‘treat’ children with cancer
Children with cancer may benefit from a different kind of treatment – a healthy dose of adventure such as dog sledding, suggests new research (Source: Thinkstock Images)
Children with cancer may benefit from a different kind of treatment – a healthy dose of adventure such as dog sledding, suggests new research.
The study followed eleven children aged 10-18 years, and five chaperones including doctors and nurses, on a dog sledding expedition to Canada organised by the French non-profit organisation Sourire a la Vie.
“What I learned from this study is that we doctors have the false belief that kids with cancer cannot practice sport because they are too tired or weak from their treatments,” said corresponding author of the study Nicolas Andre from Assistance Publique Hopitaux de Marseille, France.
Share This Article
“These perceptions are at least partly wrong,” Andre said.
“Adapted physical activities can be performed by most children with cancer even during their treatment and can bring a lot to children,” Andre noted.
All of the eleven children received adapted physical training and exercises before the expedition.
The children successfully completed the programme without harm – and they demonstrated statistically significant improvement in both physical and psychological health.
The findings appeared in the journal ecancermedicalscience.
Based on the success of this study, the researchers said they would initiate a randomised trial to evaluate the benefits of adapted physical activities for children with cancer.

Skipping breakfast may be bad for diabetics
Diabetes patients who miss their morning meal have higher-than-usual surges in blood sugar after lunch and dinner, the study found. (Source: Thinkstock Images)
People with type 2 diabetes who skip breakfast and fast until noon may have blood sugar spikes throughout the day, a small study suggests.
When 22 patients with type 2 diabetes missed their morning meal, they had higher-than-usual surges in blood sugar after lunch and dinner, the study found.
Skipping breakfast was also linked to less efficient processing of glucose by the body, or a reduced ability to convert blood sugar into energy.
The researchers had expected that skipping breakfast wouldn’t be healthy. But they were surprised at the extent to which glucose metabolism suffered, simply because participants hadn’t eaten breakfast, said lead author Daniela Jakubowicz of Tel Aviv University.
“This means reducing the amount of starch and sugars in lunch and dinner will have no effect on reducing elevated glucose levels if patients also skip breakfast,” she said by email.
Globally, about one in 10 adults have diabetes, according to the World Health Organization. Like the patients in this study, most have type 2 diabetes, which is associated with obesity and aging and occurs when the body can’t make or process enough of the hormone insulin.
Previous research has linked skipping breakfast to an increased risk for weight gain and diabetes, Jakubowicz and colleagues note in the journal Diabetes Care.
The current study involved 12 men and 10 women who were about 57 years old on average, and overweight.
On test days, patients were asked to fast overnight, then come to the clinic for blood tests and either two or three meals, depending on which part of the experiment they were completing.
Participants consumed the same balanced meal with the same number of calories for lunch and dinner.
Two to four weeks later, they repeated the process, but switching to either eat or skip breakfast – whatever they hadn’t done in the first phase.
On test days when patients skipped breakfast, their blood sugar was 40 percent higher after lunch and 25 percent higher after dinner than on the days when they had three meals.
Skipping breakfast may have made it difficult for the pancreas to produce the right amount of insulin to properly control blood sugar, Jakubowicz said. Normally, beta cells in the pancreas release insulin in response to elevated levels of sugar in the blood.
Missing the morning meal may cause the beta cells to “forget their vital role,” she said, delaying the release of insulin and allowing blood sugar levels to remain high for longer periods of time after lunch and dinner.
Because the study only included people with diabetes, it’s not clear whether healthy people would experience similar blood sugar spikes after skipping breakfast, the researchers acknowledge. It’s also unclear how long the blood sugar spikes might last.
It’s also possible that the last meal the night before might influence blood sugar the following day regardless of whether or not they ate breakfast, said Tanya Zilberter, a researcher in metabolic diseases with the Institut de Neurosciences des Systèmes in Marseille, France.
A late dinner might lead to high blood sugar the next day, Zilberter, who wasn’t involved in the study, said by email.
“It might be that the duration of the overnight fast matters more than the timing of the first meal of the day,” Zilberter said.

‘Leaky’ vaccines could make diseases more deadly: study
More harmful viruses can evolve from the use of so-called “leaky” vaccines, researchers, including one of Indian-origin, have confirmed for the first time.
More harmful viruses can evolve from the use of so-called “leaky” vaccines, researchers, including one of Indian-origin, have confirmed for the first time.
Scientific experiments with the herpesvirus such as the one that causes Marek’s disease in poultry have confirmed the highly controversial theory that some vaccines could allow more-virulent versions of a virus to survive, putting unvaccinated individuals at greater risk of severe illness.
“The challenge for the future is to identify other vaccines that also might allow more-virulent versions of a virus to survive and possibly to become even more harmful,” said Andrew Read, an author of the paper published in the journal PLoS Biology, from the Penn State University.
“When a vaccine works perfectly, as do the childhood vaccines for smallpox, polio, mumps, rubella, and measles, it prevents vaccinated individuals from being sickened by the disease, and it also prevents them from transmitting the virus to others,” Read said.
These vaccines are a type that is “perfect” because they are designed to mimic the perfect immunity that humans naturally develop after having survived one of these diseases.
“Our research demonstrates that another vaccine type allows extremely virulent forms of a virus to survive – like the one for Marek’s disease in poultry, against which the poultry industry is heavily reliant on vaccination for disease control,” said Venugopal Nair, who led the research team in the UK where the experimental work was carried out.
“These vaccines also allow the virulent virus to continue evolving precisely because they allow the vaccinated individuals, and therefore themselves, to survive,” said Nair, who is the head of the Avian Viral Diseases programme at the Pirbright Institute in UK.
Less-than-perfect vaccines create a ‘leaky’ barrier against the virus, so vaccinated individuals sometimes do get sick, but typically with less-virulent symptoms.
Because the vaccinated individuals survive long enough to transmit the virus to others, the virus also is able to survive and to spread throughout a population.
“In our tests of the leaky Marek’s-disease virus in groups of vaccinated and unvaccinated chickens, the unvaccinated died while those that were vaccinated survived and transmitted the virus to other birds left in contact with them,” Nair said.
“Our research demonstrates that the use of leaky vaccines can promote the evolution of nastier ‘hot’ viral strains that put unvaccinated individuals at greater risk,” he said.
The World Health Organisation recently reported laboratory-confirmed cases in China of human infection with the avian influenza virus, researchers said.
“We humans never have experienced any contagious disease that kills as many unvaccinated hosts as these poultry viruses can, but we now are entering an era when we are starting to develop next-generation vaccines that are leaky because they are for diseases that do not do a good job of producing strong natural immunity – diseases like HIV and malaria,” Read added.

Eat slowly to feel fuller: Study
Previous studies have found that slow eaters have lower Body Mass Index than those who gobble down their morsels. (Source: Thinkstock Images)
Go slow while eating your food as people who eat slowly feel fuller and think they have eaten more than those who eat quickly, shows research.
Previous studies have found that slow eaters have lower Body Mass Index (BMIs) than those who gobble down their morsels. But the reasons were not well understood.
To investigate whether how quickly we eat influences how hungry we feel afterwards, researchers from the University of Bristol fed volunteers Sainsbury’s tomato soup through a tube into their mouths, Daily Mail reported.
This set-up prevented the researchers from judging visually how much soup had been eaten. The participants then had 400 ml of soup put into their mouths at two rates. One was at a fast rate of 11.8 ml for two seconds, followed by a four second pause.
The other, the slow rate, was 5.4 ml of soup for one second followed by a 10-second pause. The volunteers were then asked how full they felt at the end of the meal and two hours after.
Those who took the soup more slowly said they felt fuller than the fast eaters both immediately after the test and two hours later.

Is your food really ‘chemical-free’?
Bananas contain more chemicals than some sweets and is the dosage of chemical, rather than the chemical itself, which often causes problems, Daily Mail reported. (Source: Thinkstock Images)
Are you obsessed with detox food products that are supposedly free from chemicals? Well, there is no such thing as a “chemical free” food, shows a research.
No matter what the companies selling detox products say, in reality chemicals are in everything we eat — though all may not be unhealthy, a video created by a Toronto-based web portal ASAP Science shows.
It shows how bananas, for example, contain more chemicals than some sweets and explains that it is the dosage of chemical, rather than the chemical itself, which often causes problems, Daily Mail reported.
In the video, scientists explain that while many people will advise against eating food which contains chemicals that are hard to pronounce, yet a single blueberry contains chemicals like methylbutyrate and oleic acid benzaldehyde, among many more.
And in some cases, healthy foods contain more chemicals than processed sweets. In an example, a banana is shown containing more than 50 chemicals from riboflavin to histidine.
“Everything around us is made up of chemicals from the water you drink to the air you breathe, which is why it is frustrating when companies consistently tout their foods as chemical-free,” scientists said.
“Seriously, we can break down any food to look like a confusing long list of foreign ingredients,” scientists added.
The video continues that even non-harmful chemicals in food have the potential to become harmful at higher doses.

Are you consuming enough fiber?
Recommended amount of dietary fiber per day is 38 grams for men and 25 grams for women. (Source: Thinkstock Images)
Are you consuming enough fiber? A new study has revealed that the people, who get fiber from natural sources and manufactured sources, may benefit more than those who limit their intake to a single type.
Julie Miller Jones, a professor emeritus at St. Catherine University, has found that Americans fall short of the recommended amount of dietary fiber per day that is 38 grams for men and 25 grams for women. Men typically get around 18 grams and women get around 15 grams.
She cited a 2014 study that found a decline in the number of Americans, who said they are trying to eat more fiber, from 73 percent in 2010 to 53 percent in 2014.
Jones said that the real problem was that we don’t know we have a problem.
She added that when people don’t know they have a problem, they don’t know how to address it.
Jones further said that thirty-five percent of the people in America think that they are getting enough fiber, adding that it is a big job in terms of informing people about not getting enough fiber.
Jones said that consumers should strive for a mix of fiber sources, including fiber that has been added to food in the manufacturing process.
In addition, Jones noted that each type of fiber carries its own unique benefits.

Grandma’s tip: Fat burner is right in your backyard
Health effects of Garcinia Indica, popularly known as kokum, include anti-obesity and anti-cancer.
The demand for fat burning pills seems to be growing, for obvious reasons. What seems to have been missed is the fact that the most sought after popular fat burner — Garcinia Indica — is available right in our backyards.
Popularly known as kokum in India, Garcinia Indica has been used for centuries in Asian countries for culinary purposes as a condiment and flavoring agent in place of tamarind and lemon. It’s used in juices, pickles and to add sourness to curries.
Kokum tree is predominantly grown in the tropical humid rainforests of Western Ghats in South India. The fruits are green when raw and red to dark purple when fully ripe. Kokum is widely used as a beverage and also has been used as a medicine in traditional Indian Ayurveda.
A myriad of health effects have been attributed to Garcinia, which range from anti-obesity effects, anti-inflammatory, anticancer to digestive benefits. The anti-obesity effects of Garcinia Indica come specifically from its hydroxycitric acid (HCA), and have been elucidated in several studies over the past few decades. However, there are controversial results regarding its efficacy and safety as an anti-obesity dietary supplement. Despite this, the market is flooded with a plethora of over-the-counter slimming aid containing Garcinia & HCA.
A typical reduction of food appetite is reported and increased availability of mood enhancing neuro-transmitter Serotonin has been observed in animal and human studies with Garcinia. Besides this effect, it helps to enhance fat oxidation, reduces the tendency to store fat and leptin resistance. In other words, it suppresses fatty acid synthesis, formation of fat cells, food intake and induces weight loss. While several studies report strong evidence, others show negative anti-obesity effects.
Besides weight loss, it is also found to be useful in treating obesity-related complications such as inflammation, oxidative stress and insulin resistance.
Kokum has been associated with several other nutritional and health benefits owing to its phytochemicals like anthocyanins and several other phenolic components. A recent animal study published in 2014 in the Journal of Biomedicine & Aging Pathology, reported that intake of Garcinia improved ulcers, owing to its underlying antioxidant activity.
Another useful component of kokum is Garcinol, which has been found to be neuro-protective, contributing to brain health and preventing Alzheimer’s.
Different parts of this plant, including its fruit, rind and seed, have different applications in food and medicine. Rind is typically used for food and in pharma industry, while the kokum seeds are used to prepare butter, which is often used in cosmetics and medicines.
While it is clear that kokum and various parts of the plant have a role to play in weight loss and obesity management, it must be emphasised that there is no miracle or magic about it. A carefully planned diet and exercise are key to obesity management. Fat burners, be it herbs, vitamins or minerals, can only be supportive and work as adjuncts. It will be wise to take any of these in its natural form as food. A glass of kokum juice is a cooling digestive beverage and certainly needs no prescription.

Why physicians prescribe costly medicines
The kind of medicines (cheaper or costly) a doctor prescribes is influenced by the prescriptions made by senior physicians who supervised them during the training, says a study. (Source: Thinkstock Images)
Does your doctor often prescribe costly, big brand medicines? The decision may have to do with his training.
The kind of medicines (cheaper or costly) a doctor prescribes is influenced by the prescriptions made by senior physicians who supervised them during the training, says a study.
The results represent an opportunity for improvement in graduate medical education at a time when in India the government is emphasising on physicians prescribing generic medicines instead of brand names to make healthcare more affordable for the masses.
The study, published online in the Journal of General Internal Medicine, found that physicians-in-training are twice as likely to order a costly brand-name statin (used to lower blood cholesterol levels) when supervised by senior physicians who prefer those medications in their own practice.
These results document a link between low-value prescribing and graduate medical training, which physicians undergo after completing medical school but before they can practice independently.
The study found that the probability of a resident prescribing a costly brand-name statin increased from 22.6 percent when residents were supervised by attending physicians who mostly prescribed cheaper generic statins, to 41.6 percent when they were supervised by an attending who mostly prescribed expensive brand name statins.
The linkage was strongest for the most junior resident physicians in training.
“These results provide early empirical evidence that low-value practices among physicians are transferred from teachers to trainees, highlighting the importance of re-design of graduate medical education,” said Kira Ryskina, a general internal medicine fellow at University of Pennsylvania.
“We observed considerable variation in the prescribing practices of both attending physicians and residents, suggesting room to improve cost-effectiveness,” Ryskina said.

World’s first malaria vaccine gets go-ahead from EU regulators
Malaria killed an estimated 584,000 people in 2013, the vast majority of them in sub-Saharan Africa. More than 80 percent of malaria deaths are in children under the age of five. (Source: Thinkstock Images)
The world’s first malaria vaccine got a green light on Friday from European drugs regulators who recommended it should be licensed for use in babies in Africa at risk of the mosquito-borne disease.
The shot, called RTS,S or Mosquirix and developed by British drugmaker GlaxoSmithKline in partnership with the PATH Malaria Vaccine Initiative, would be the first licensed human vaccine against a parasitic disease and could help prevent millions of cases of malaria in countries that use it.
Recommendations for a drug license made by the European Medicines Agency (EMA) are normally endorsed by the European Commission within a couple of months.
Mosquirix, also part-funded by the Bill & Melinda Gates Foundation, will also now be assessed by the World Health Organization, which has promised to give its guidance on when and where it should be used before the end of this year.
Malaria killed an estimated 584,000 people in 2013, the vast majority of them in sub-Saharan Africa. More than 80 percent of malaria deaths are in children under the age of five.
Andrew Witty, GSK’s chief executive, said EMA’s positive recommendation was a further important step toward making the world’s first malaria vaccine available for young children.
“While RTS,S on its own is not the complete answer to malaria, its use alongside those interventions currently available such as bed nets and insecticides would provide a very meaningful contribution to controlling the impact of malaria on children in those African communities that need it the most,” he said in a statement.
Global health experts have long hoped scientists would be able to develop an effective malaria vaccine, and researchers at GSK have been working on RTS,S for 30 years.
Hopes that this shot would be the final answer to wiping out malaria were dampened when trial data released in 2011 and 2012 showed it only reduced episodes of malaria in babies aged 6-12 weeks by 27 percent, and by around 46 percent in children aged 5-17 months.
EMA’s recommendation is that the shot should nevertheless be licensed for use in babies in the full age range covered in the trials — from 6 weeks to 17 months.
Some malaria specialists have expressed concern that the complexities and potential costs of deploying this first vaccine when it only provides partial protection make it less attractive and more risky.
However Joe Cohen, a GSK scientist who has led the development of Mosquirix since 1987, said on Friday he has no doubt the vaccine could significantly reduce the toll of sickness and death caused by the malaria among African children.
“I have absolutely no reservations in terms of rolling this vaccine out,” he told Reuters. “Why? Because the efficacy, when translated into cases averted and deaths averted, is just tremendous. It will have an enormously significant public health impact.”

Two cheap generic drugs can cut breast cancer deaths
“The studies provide really good evidence that the inexpensive, generic drugs can help to reduce breast cancer mortality in postmenopausal women”. (Source: Thinkstock Images)
Two different classes of inexpensive generic drugs can each improve survival prospects for post-menopausal women with early breast cancer, researchers have reported in two studies.
About two-thirds of all women with breast cancer are post-menopausal.
The two types of drugs – aromatase inhibitors (AIs) and bisphosphonates – can be used together, increasing the benefits while also decreasing some side-effects, the findings published in the journal The Lancet showed.
“These studies provide really good evidence that both of these inexpensive, generic drugs can help to reduce breast cancer mortality in postmenopausal women,” said lead statistician for both studies Richard Gray, professor at University of Oxford.
“The drugs are complementary, because the main side effect of aromatase inhibitors is an increase in bone loss and fractures, while bisphosphonates reduce bone loss and fractures as well as improving survival,” Gray pointed out.
The first study analysed data from 30,000 post-menopausal women who participated nine randomised trials.
The researchers found that compared to standard therapy, taking AIs for five years further reduced the likelihood of the cancer recurring by about a third, and the risk of dying from breast cancer by around 15 percent throughout the decade after beginning treatment.
The researchers estimated that, compared to no endocrine treatment, the risk of dying from breast cancer for women who took AIs would be reduced by around 40 percent in the decade after beginning treatment.
The second study found that two-five years of treatment with a class of drugs called bisphosphonates, which are usually used to treat osteoporosis, reduces the risk of breast cancer recurring in post-menopausal women, and also significantly extends survival. However, bisphosphonate treatment appears to have little effect in premenopausal women.
The most common site for breast cancers to spread to is bone and the researchers found that bisphosphonates treatment resulted in 17 percent reduction in recurrence of cancer in the bone.
However, among post-menopausal women, bisphosphonate treatment produced larger reduction in bone recurrence of 28 percent and also reduced the risk of dying from breast cancer by 18 percent during the first decade after diagnosis.

Whole fat butter may control diabetes in humans
“Butter may have both good and bad saturated fats but it is always best to check with your physician before making changes to your diet,” the authors concluded. (Source: Thinkstock images)
A unique saturated fat found in fish and whole fat daily products can reverse diabetes, researchers have reported after discovering that dolphins suffering from prediabetes were cured when fed with a modified diet rich in the saturated fat.
The researchers are hopeful that controlled doses of this saturated fat called heptadecanoic acid may help reverse prediabetes in humans soon.
Because of the popularity of fish-based omega-3 fatty acids as a human health supplement, the team from the US National Marine Mammal Foundation (NMMF) assessed fatty acid blood levels in 49 dolphins as well as in their dietary fish.
“We were surprised to find that among the 55 fatty acids studied, the saturated fat heptadecanoic acid appeared to have had the most beneficial impact on dolphin metabolism,” said Stephanie Venn-Watson, director of NMMF’s translational medicine and research programme.
Dolphins with higher levels of heptadecanoic acid in their blood had lower insulin and triglycerides, he said.
The study also showed that while some fish have high levels of heptadecanoic acid other fish types had none.
Six dolphins with low heptadecanoic acid were then fed fish high in this fatty acid.
Within six months on the new diet, indicators of metabolic syndrome in dolphins, including elevated insulin, glucose, and triglycerides normalised.
Key to this surprising outcome was reversal of high ferritin, an underlying precursor to metabolic syndrome.
“We saw blood ferritin levels decrease in all six dolphins within three weeks on the new diet,” Venn-Watson said.
Heptadecanoic acid, also called margaric acid, is found in dairy fat, rye and some fish.
The fish with the highest heptadecanoic acid content was mullet.
“We hypothesise that widespread movement away from whole fat dairy products in human populations may have created unanticipated heptadecanoic acid deficiencies,” Venn-Watson contended.
“This dietary deficiency may be playing a role in the global diabetes pandemic,” he warned in a paper that appeared in the journal PLOS ONE.
Does this mean that we can now eat butter without guilt?
“Butter may have both good and bad saturated fats but it is always best to check with your physician before making changes to your diet,” the authors concluded.

Say no to dandruff trouble this monsoon
Combining an anti-dandruff shampoo containing active ingredients with a mild conditioner formulated for greasy hair. (Source: Thinkstock Images)
Hair care during monsoon becomes a herculean task and one of the most common woes during the rainy season is dandruff. From using a diet low in sugar and high in antioxidants to opting for light conditioner can help in getting rid of such problems, says an expert.
Sangeeta Velaskar, vice president and head, Medical Services and R&D, Kaya India has a few tips to help control dandruff:
* Use an effective anti-dandruff shampoo specially formulated with active ingredients such as zinc pyrithione or piroctone olamine, which control the fungus and yeasts. Such a shampoo can be used as often as required — once, twice or even thrice weekly. Combine it with a mild conditioner formulated for greasy hair.
* It is important to keep the scalp dry. In case your hair gets wet in the rain, make sure you wash it thoroughly with a mild cleanser and use a conditioner thereafter. Remember to dry your hair completely before leaving the house.
* If you have sticky hair, just opt for a light conditioner that is suited for limp and oily hair. The trick is to pick the right product. The conditioner should be applied to the hair ends and not on the scalp. Application on the scalp may increase dandruff, especially during monsoon.
* Recognise your severity. If you are suffering more than moderate flaking and itching, be sure to find the right product. There are products that include intensive solutions targeted at severe dandruff sufferers. Do visit a dermatologist if the problem persists.
* A diet low in sugar and high in antioxidants will reduce inflammation and could help in controlling dandruff.

Successful people at extra risk of harmful drinking
Harmful drinking is a “middle-class phenomenon” that may be a hidden health and social problem in otherwise successful older people, said researchers. (Source: Thinkstock Images)
People who are in their 50s and are “successful agers” – healthy, active, sociable and well off – are more at the risk of harmful drinking than their less successful peers, researchers have warned.
Harmful drinking is a “middle-class phenomenon” that may be a hidden health and social problem in otherwise successful older people, they added.
“We can sketch the problem of harmful drinking among people aged 50 or over as a ‘middle class phenomenon’. These are healthy people with higher income, higher educational attainment, socially more active and are more likely to drink at harmful levels,” the authors wrote in the BMJ Open journal.
Higher risk of harmful drinking was not linked to feelings of loneliness or depression but it was more likely among men living on their own, including those who were separated or divorced.
Caring responsibilities lowered the probability of being at higher risk among women, but religious belief did not – for either sex.
Employment status did not seem to be a significant factor but women who had retired were more likely to be at higher risk, the study noted.
Income was associated with a higher risk but only among women while smoking, higher educational attainment and good health were all linked to heightened risk in both sexes.
The authors analysed over 9000 responses to the English Longitudinal Survey of Ageing (ELSA) – a long term study of a representative sample of those aged 50 and above living independently at home in England.
They used national guidance to define increasing risk of harmful drinking at 22-50 weekly units for men and 15 to 35 weekly units for women.
“The results show that the current group of over 50s may be carrying on levels of higher consumption, developed in their younger years, in later life,” the researchers concluded.
