What proteins should you eating?

Our body is made up mostly of protein that is constantly being broken down, so it’s vital to replace it by eating high protein foods that are lean, low fat or fat free

Poultry: Chicken or turkey is great choices – just skip legs and thighs and go with skinless breasts.

Beef: Lean cuts include round steaks and roasts, top loin and sirloin, chuck shoulder and arm roasts, and extra lean ground beef.

Pork: For flavor and leanness go with pork loin, tenderloin, center loin cuts.

Eggs: The yolk holds about 80 percent of an egg’s calories. Stick to just the whites and you can eat more. Two whole eggs have 150 calories and 10g fat versus 10 egg whites which have 140 calories and zero fat.

Fish: Canned salmon and tuna are convenient protein choices; of the two salmon is higher in omega 3’s and calcium.

Nuts: A single serving of nuts is about 1.5 ounces; the number of nuts you get depends on  the nut you choose:  Pistachios 47-49; Almonds 20-24; Cashews 16-18; Walnuts 10-14 halves; Macadamias 10-12; Brazil nuts 6-8.

Tofu: This low-fat, low-calorie protein is super-versatile because it absorbs flavors easily. Go with tofu steeped in a low-calorie, low-sodium marinade and stir-fry with your favorite vegetables.

Scientists find possible new way of fighting high blood pressure

Researchers at Britain’s Bristol University removed nerve links between the brain and the carotid body blood pressure fell and remained low.

Scientists experimenting with rats have found that de-activating certain nerves in the neck can effectively treat high blood pressure – a discovery that could be an advance in tackling one of the world’s biggest silent killers.

Researchers at Britain’s Bristol University found that in rats with high blood pressure, when they removed nerve links between the brain and the carotid body – a nodule about the size of a grain of rice on the side of each carotid artery – the animals’ blood pressure fell and remained low.

The researcher’s results, published in the journal Nature Communications on Tuesday, have already led the team on to conduct a small human trial of the technique, with results expected at the end of this year.

Hypertension, or high blood pressure, is referred to by the World Health Organization as one of the world’s biggest silent killers because most people who have it can’t feel or see it.

It affects around one in three people worldwide and can cause stroke, heart attacks and kidney failure.

After diagnosis, treatment of high blood pressure needs to lifelong and many patients are able to manage their condition with anti-hypertension drugs. But experts say that for around 1 in 50 of them, medication does not help.

Julian Paton, who led this latest study at Bristol’s school of physiology and pharmacology, said while scientists already knew of a link between the carotid organs and hypertension, until now them “had absolutely no idea that they contributed so massively to the generation of high blood pressure.”

Tim Chico, as consultant cardiologist at the University of Sheffield who was not directly involved in the research, described the technique as “exciting and innovative” but cautioned that more work was needed to assess its effectiveness and safety before it could be considered for use in patients.

Normally, Paton explained, the carotid body acts to regulate the amount of oxygen and carbon dioxide in the blood.

It is stimulated when oxygen levels fall in the blood – such as when someone is holding their breath. This then causes a dramatic increase in breathing and blood pressure until blood oxygen levels are restored.

Having established that this response comes about through a nerve connection between the carotid body and the brain, Paton’s team decided to block the nerve endings in the neck and found that it swiftly brought their blood pressure down.

Jeremy Pearson, associate medical director at the British Heart Foundation, which part-funded this latest research, said all eyes are now on the human trial aiming to find out whether the treatment might work in people with high blood pressure who don’t get better with current drugs.

Tony Heagerty, a professor of medicine at Manchester University who was not involved in the study, said it was an interesting development which could “potentially avoid the use of drugs which have to be taken on a daily basis for many years.”

European men grow 11cm in a century

The average height of European men grew by a surprising 11 centimeters from the early 1870s to 1980, reflecting significant improvements in health across the region, according to new research published on Monday.

Contrary to expectations, the study also found that average height accelerated in the period spanning the two World Wars and the Great Depression, when poverty, food rationing and hardship of war might have been expected to limit people’s growth.

The swift advance may have been due to people deciding to have fewer children in this period, the researchers said, and smaller family size has previously been found to be linked to increasing average height.

“Increases in human stature are a key indicator of improvements in the average health of populations,” said Timothy Hatton, a professor economics at Britain’s University of Essex who led the study.

He said the evidence – which shows the average height of a European male growing from 167 cm to 178 cm in a little over a 100 years – suggests an environment of improving health and decreasing disease “is the single most important factor driving the increase in height”.

The study, published online in the journal Oxford Economic Papers, analyzed data on average men’s height at around the age of 21 from the 1870s up to around 1980 in 15 European countries.

The study only looked at men, the researchers said, because extensive historical data on women’s heights is hard to come by.

For the most recent decades, the data on men were mainly taken from height-by-age surveys, while for the earlier years the analysis used data for the heights of military conscripts and recruits.

On average, men’s height had grown by 11 centimeters (cm) in just over a century, the researchers found, but there were differences from country to country.

In Spain, for example, average male height rose by around 12 cm from just under 163 cm in 1871-1875 to just under 175 cm in 1971-5, while in Sweden, men’s average height increased by 10 cm from just over 170 cm to almost 180 cm in the same period.

The researchers found that in many European countries – including Britain and Ireland, the Scandinavian countries, Netherlands, Austria, Belgium and Germany – there was a “distinct quickening” in the pace of advance in the period spanning the two World Wars and the Great Depression.

“This is striking because the period largely predates the wide implementation of major breakthroughs in modern medicine and national health services,” they wrote.

Hatton said one possible reason, alongside the decline in infant mortality, for the rapid growth of average male height in this period was that there was a strong downward trend in fertility at the time – and smaller family sizes have previously been found to be linked to increasing height.

Other height-boosting factors included higher per capita incomes, more sanitary housing and living conditions, better education about health and nutrition and better social services and health systems

Researchers discover potential epilepsy drug using zebrafish

An antihistamine used to treat itching may be the key to preventing seizures in children with a rare, yet severe form of epilepsy known as Dravet Syndrome.

The discovery was made by screening hundreds of government-approved drugs in animals with the same genetic mutation as children with the disorder.  But instead of using rodents – the typical animal model for drug screenings – researchers used an unlikely test subject for their experiment: zebrafish.

According to the researchers, the antihistamine known as clemizole could be the first line approach for reducing the effects of Dravet Syndrome – a condition with very limited treatment options.

“Dravet Syndrome is a catastrophic form of childhood epilepsy, and it often leads to severe symptoms and death,” Scott Baraban, a professor of neurological surgery at the University of California, San Francisco and William K. Bowes Jr. Endowed Chair in neuroscience research, told FoxNews.com.  “Within the first year of life, children will start to have seizures and have several hundred per day.  They’ll have delays in speech, cognitive problems, ataxia, which is trouble standing… And while there are drugs that are given that reduce the effects, there aren’t too many treatment options for these kids.”

Baraban first pioneered the idea of using the small, translucent zebrafish to test drugs for epilepsy in 2005, as the zebrafish’s genome is 80 percent identical to the human genome. In order to better understand the effects of a certain drug, researchers place zebrafish larvae – which are no longer than a human eyelash – into petri dish baths filled with that drug.  Since the larvae require the water for respiration, the drug immediately enters their systems through the bath, allowing researchers to quickly observe how the fish respond.

“The fact that fish are permeable to the drug – that’s a huge advantage for drug screening,” Baraban said. “Most drugs are tested using a cell-based culture, but when drugs move on to next stage in the animal model, they’re often toxic.  So the advantage with zebrafish is we can test effectiveness and toxicity of the drug at the same time.”

Baraban decided to use this drug screening method for Dravet Syndrome after he came across a zebrafish with a mutation in the SCN1A gene, the same genetic mutation commonly associated with the epileptic disorder.  The SCN1A gene codes for a voltage activated sodium channel, which allows ions to pass through the membranes of neurons and regulate how they fire.  In Dravet Syndrome, these channels allow too many ions to pass through the neural membranes, causing the neurons to fire excessively.

Zebrafish with the SCN1A gene mutation showed the same developmental pattern as children with the mutation, moving around in erratic patterns whenever they experienced a seizure.  Just as children with Dravet Syndrome begin having seizures one year after birth, the fish began experiencing seizures three days after fertilization.  And though the fish typically died after just 10 to 12 days, Baraban said they are extremely easy to breed, yielding incredibly large cohorts for testing.

“One breeding pair will give 100 pairs of eggs, so one quarter of the offspring will have the mutation we’re interested in – and they’ll have spontaneous seizures,” Baraban said. “We decided to do a hyper approach screening, where we take a library of commercially available drugs and screened them to see if they stop the seizures in fish.”

Baraban’s team tested a random assortment of 320 compounds in a chemical library of drugs that had already been approved by the Food and Drug Administration.  Through this indiscriminate testing, they stumbled upon the antihistamine clemizole, which eliminated the seizure activity in the fish within 10 minutes of application.

The reason behind clemizole’s efficacy remains a mystery, especially since antihistamines can sometimes make seizures worse.  The researchers even tested 10 other antihistamines on the fish, but none was successful at blocking the seizures.  Baraban theorized that another biological mechanism in clemizole, apart from its antihistamine properties, is responsible for the therapeutic effects.

Because clemizole is already FDA-approved, Baraban hopes it can soon be tested in small clinical trials of people suffering from Dravet Syndrome and that it will produce little to no side effects.  He is also fairly confident the drug will be effective in humans, since the mutant zebrafish so closely mirrored humans with the condition.

“We screened (the zebrafish) with epilepsy drugs already given to kids with Dravet Syndrome, and the fish predicted the same compounds,” Baraban said.  “So the drugs that work in humans also worked in fish, and the drugs that didn’t work in humans didn’t work in the fish.  So it suggests that clemizole could be directly applicable.”

Not only is Baraban’s research inspiring for people suffering from Dravet Syndrome, but his zebrafish method could be used to find therapeutic agents for various other conditions caused by mutations in a single gene.  He said this technique offers a much more tailored approach to drug screening.

“There’s no reason you couldn’t model lots of different genetic disorders in zebrafish,” Baraban said. “So genetic forms of Alzheimer’s, Parkinson’s, they can all be modeled in zebrafish and used in drug screening.  And in the epilepsy field this is just one example.  So if you’re child has a gene mutation, we can make fish with that specific gene mutation and screen for drugs that are effective for your children.”

The research was published online in the journal Nature Communications.

How to keep your kidneys healthy

caring for your kidneys is very important because when it becomes damaged, the waste products and fluid get assembled in the body and can cause several illnesses leading to fatal conditions later in life.

Kidneys are essential in the urinary system and serve the body as a natural filter of the blood. They remove wastes and excess fluid thus cleansing your blood in your body. Kidneys maintain the balance of salt and minerals in your blood and help regulate blood pressure.

Taking care of your kidneys will help you to take care of the rest of your body. Kidneys are two small organs located at the rear of the abdominal cavity in the retroperitoneum performing several life-sustaining roles.

Therefore, caring for your kidneys is very important because when it becomes damaged, the waste products and fluid get assembled in the body and can cause several illnesses leading to fatal conditions later in life.

Chronic kidney disease (CKD), also known as chronic renal disease is dangerous and is characterised by a steady loss in renal function over time.

Chronic kidney disease (CKD) is classified into five stages with stage 1 being the mildest and usually causing few symptoms and stage 5 being a severe illness with poor life expectancy if untreated. The last stage is also called end stage renal disease (ESRD) or end stage renal failure (ESRF) where a patient needs dialysis or transplants to stay alive.
The most common causes of CKD are diabetes, heart disease, hypertension and a family history of kidney failure. Other risks include: obesity, autoimmune diseases, urinary tract infections and systemic infections.

The National Kidney Foundation of India, an NGO, ranked kidney diseases as third amongst life-threatening diseases (after Cancer and Cardiac ailments) in the country. It also estimates that 100 people in a million succumb to kidney ailments and around 90,000 kidney transplants are required annually in India.

Below are some tips to help you keep your kidneys healthy:

– Follow a healthy diet by choosing foods that are healthy for your heart such as fresh fruits and vegetables, whole grains, low-fat dairy foods, etc.
– Do not smoke.
– Limit your alcohol intake.
– Exercise regularly.
– Maintain a healthy weight to avoid overweight.
– Reduce salt in your diet.
– Keep your blood pressure and cholesterol under control.
– Do not overuse over-the-counter painkillers or NSAIDs.
– Drink plenty of fluids/water
– Seek medical help or talk to your doctor if you think you are at risk of for CKD.

BMI has no role in cardiovascular disease in a healthy woman

obese women have a window of opportunity to lose weight and avoid developing a metabolic disorder, which would increase their CVD risk.

Metabolically healthy women have same cardiovascular disease risk regardless of their having different BMIs, according to a study.

Dr Soren Skott Andersen and Dr Michelle Schmiegelow from Denmark findings in more than 260,000 subjects suggest that obese women have a window of opportunity to lose weight and avoid developing a metabolic disorder, which would increase their CVD risk.

The study used Danish national health databases and followed 261,489 women who had given birth during 2004-2009 with no prior history of cardiovascular disease. The women were divided into four categories according to their pre-pregnancy body mass index (BMI, kg/m2) and presence of metabolic disorders (present/not present). The women`s mean age was 31 years.

The women were followed for an average of 5 years following childbirth. Discharge diagnoses and data on cause of death were used to determine if the women had a heart attack, a stroke, or died.

The researchers found that being overweight ( BMI=25 kg/m2) but metabolically healthy was not associated with an increased risk of a heart attack, stroke or a combination of heart attack/stroke/death in comparison with normal weight, metabolically healthy women.

The investigators found that the metabolically unhealthy, overweight women had an almost 7-fold increased risk of heart attack and a 4-fold increased risk of stroke.

 

Ovarian tissue transplant – A new hope for female cancer survivors

Healthy ovarian cortical tissue is removed using laparoscopic surgery from the woman about to undergo cancer treatment.

Cancer treatments, like chemotherapy or radiation therapy, highly hinder both hormonal production and reproductive potential in women, as the treatments attack fast growing cells in the body.

However, with an Australian woman, rendered infertile by ovarian cancer treatment, expecting twins after successfully undergoing ovarian tissue transplantation, doctors are expecting that the new technique could revolutionize fertility treatment.

Though the procedure had been carried out previously, this is for the first time that the tissue has been successfully transplanted into the abdomen instead of the ovaries.

Ovarian tissue transplant: How it is done

Healthy ovarian cortical tissue is removed using laparoscopic surgery (keyhole surgery) from the woman about to undergo cancer treatment. The minimally invasive procedure lasts approximately 1 hour and requires general anesthesia.

The ovary`s cortex is cut into tiny 1 millimeter thick strips and then frozen to be used for future transplantation.

Once the patient goes into remission post cancer treatment and plans to have a baby several slices of the previously frozen ovarian tissue can then be thawed and implanted near the fallopian, either orthotopic (on the natural location) or heterotopic (on the abdominal wall).

The cortex tissue strips contain immature follicles, once implanted back into the body start producing hormones and eggs like a normal ovary following which a woman starts to ovulate and can try for pregnancy either naturally or through in vitro fertilization (IVF) technique.

The low cost technology saves premature babies

GE Healthcare created the Lullaby baby-warmer, to help to save lives in a country

Premature babies have very little body fat and are unable to regulate body temperature. Every year more than 20 million babies are born prematurely or with low birth weight – and an estimated 450 of them die each hour.

Yet most of these deaths could be avoided by simply keeping them warm.

“A new-born baby wailing can generally be heard outside the room – even across the hallway. But not my baby Mine can only whimper,” says Jayalakshmi Devi.

She’s standing outside the neo-natal intensive care unit (ICU) staring at the glass box where her baby son is kept.

Born too soon, her baby boy weighs less than 1.2 pounds (0.54kgs). Doctors have given him around a 40% chance of survival.

Having lost two babies already, Jayalakshmi didn’t want to take a chance this time. After delivering her child in a rural healthcare centre three hours outside Bangalore, she brought the baby to the state run hospital in the city.

At Vanivilas hospital, the neo-natal ICU sees scores of premature babies. Most are born at home, in far off rural areas and are brought here in critical condition.

Row after row, the transparent boxes creates warmth to hold the tiny, bare-bodied babies with only an oversized diaper around them. Some of the babies are small enough to fit into your palm.

Life-saving warmth

A baby’s body temperature drops as soon as it is outside the controlled environment of the mother’s womb. So just after labor, it’s important to regulate the temperature.

The babies need incubators to help keep them alive – equipment which state-run hospitals like this one often cannot afford.

So, GE Healthcare created the Lullaby baby-warmer, to help to save lives in a country that has the highest rate of pre-term baby deaths in the world.

Low-cost innovation

It was developed in Bangalore and launched in 2009. The baby warmer costs $3,000 (£1,900) in India, 70% cheaper than traditional models.

The design includes pictorial warnings and color coding, so that even illiterate rural healthcare workers can operate the machine.

The Lullaby warmer also consumes less power than most incubators, which means cost savings for the healthcare centre.

“Where better to make a baby warmer than here – India produces a baby nearly every second,” says GE Healthcare’s Ravi Kaushik.

He believes India is an ideal innovation centre when it comes to products like this, because 70% of the population is rural and 30% is urban, and within this you all different stratas of society.

“So you can have very great world class hospitals that want and require world class medical equipment that America or Europe would require. But at the same time there is a population in rural space that would require same kind of medical attention,” says Mr Kaushik.

Where better to make a baby warmer than here -India produces a baby nearly every second”

Ravi Kaushik GE Healthcare

“So when you design a product, you have to cater to the entire plethora of needs. That allows you to almost hit the entire world because India is a small representation of that.”

Engineers at GE’s technology centre are stripping down lifesaving, high tech medical devices of all their frills to understand how to create products that are affordable.

This project is now widely quoted as an example of “reverse innovation”.

This is where large global companies design products in developing markets like India and then take the successful creation back to international markets to sell.

After success in the domestic market, GE now sells the warmer in more than 80 countries.

Bundled up

While this works for healthcare centers on a budget, it still needs continuous electricity to run.

But go further down the population pyramid, and the problems get more complex.

Women in villages give birth at home and have little access to basic healthcare or electricity.

For them, keeping babies warm means wrapping them in layers of fabric and hot water bottles, or putting them under bare light bulbs.

Many of them don’t survive.

But now a low cost baby bag is saving thousands of young lives. Called the Embrace, it emerged out of a class assignment at Stanford’s Institute of Design in 2007.

Four graduate students – Jane Chen, Linus Liang, Naganand Murty, and Rahul Panicker – were challenged to come up with a low-cost incubator design that could help save premature babies born into poverty.

The team created a sleeping bag with a removable heating element.

Using high school physics, they used phase-change material (PCM), a waxy substance that, as it cools from melted liquid to solid, maintains the desired temperature of 37 degrees Celsius (98.6 F) for up to six hours.

The end product looks like a quilted sleeping bag that is durable and portable. It requires only 30 minutes of electricity to warm up using a portable heater that comes with the product.

More importantly for mothers, it allows for increased contact with their child, unlike traditional incubators.

So it also encourages Kangaroo care, a technique practiced on newborn, especially pre-term infants, which promotes skin-to-skin contact to keep the baby warm and facilitate breastfeeding and bonding.

The infant warmer costs about $200 to make, is inexpensive to distribute, and is reusable.

Embrace is a non-profit venture. The product is not sold, but is donated to impoverished communities in need.

The invention is thought to have helped save the lives of more than 22,000 low birth-weight and premature infants.

Taking the program forward, the organization has developed a new version designed for at-home use by mothers. The model has been successfully prototyped and is currently undergoing clinical testing in India.

The organization has also set up educational program to address the root causes of hypothermia.

“We provide intensive, side-by-side training to mothers, caretakers, and healthcare workers,” says Alejandra Villalobos, director of development at Embrace.

“We develop long-term partnerships with local governments and non-profits in every community where we work.

“We believe that increased access to both technology and education is necessary to achieve our ultimate vision: that every woman and child has an equal chance for a healthy life.”
