Dogs may accurately sniff out cancer in blood

Published

on

Dogs can use their highly evolved sense of smell to pick out human blood samples with cancer with almost 97% accuracy, according a a study that may lead to inexpensive and non-invasive screening approaches for the deadly disease.

Dogs have smell receptors 10,000 times more accurate than humans, making them highly sensitive to odours we can’t perceive, said researchers who presented the study at the American Society for Biochemistry and Molecular Biology annual meeting in Florida, US.

“Although there is currently no cure for cancer, early detection offers the best hope of survival,” said Heather Junqueira, lead researcher at the US-based healthcare company BioScentDx.

“A highly sensitive test for detecting cancer could potentially save thousands of lives and change the way the disease is treated,” Junqueira said in a statement.

The researchers used a form of clicker training to teach four beagles to distinguish between normal blood serum and samples from patients with malignant lung cancer.

Although one beagle was unmotivated to perform, the other three dogs correctly identified lung cancer samples 96.7% of the time and normal samples 97.5% of the time.

“This work is very exciting because it paves the way for further research along two paths, both of which could lead to new cancer-detection tools,” said Junqueira.

“One is using canine scent detection as a screening method for cancers, and the other would be to determine the biologic compounds the dogs detect and then design cancer-screening tests based on those compounds,” she said.

BioScentDx plans to use canine scent detection to develop a non-invasive way of screening for cancer and other life-threatening diseases.

Low fitness may increase depression and anxiety: Study

Published

on

Researchers have found that people with low aerobic and muscular fitness are nearly twice as likely to experience depression.

Low fitness levels also predicted a 60 per cent greater chance of anxiety, over a seven-year follow-up, according to the study published in the journal BMC Medicine.

“Here we have provided further evidence of a relationship between physical and mental health, and that structured exercise aimed at improving different types of fitness is not only good for your physical health, but may also have mental health benefits,” said study author Aaron Kandola from University College London (UCL) in the UK.

The study involved 152,978 participants aged between 40 and 69 years.

Their baseline aerobic fitness at the start of the study period was tested by using a stationary bike the increasing resistance, while their muscular fitness was measured with a grip strength test.

They also completed a questionnaire gauging depression and anxiety symptoms.

Seven years later they were tested again for depression and anxiety symptoms, and the researchers found that high aerobic and muscular fitness at the start of the study was associated with better mental health seven years later.

People with the lowest combined aerobic and muscular fitness had 98 per cent higher odds of depression, 60 per cent higher odds of anxiety, and 81 per cent higher odds of having either one of the common mental health disorders, compared to those with high levels of overall fitness.

“Our findings suggest that encouraging people to exercise more could have extensive public health benefits, improving not only our physical health but our mental health too,” said study author Joseph Hayes from UCL.

Improving fitness through a combination of cardio exercise and strength and resistance training appears to be more beneficial than just focusing on aerobic or muscular fitness, according to the study.

“Other studies have found that just a few weeks of regular intensive exercise can make substantial improvements to aerobic and muscular fitness, so we are hopeful that it may not take much time to make a big difference to your risk of mental illness,” the authors wrote.

What causes your digestive system weak and unhealthy?

Published

on

A healthy digestive system can be good for your physical and mental health. Digestive system is made up of digestive tract, liver, pancreas and gall bladder. There are many good bacteria in our digestive tract which helps in digesting food. These bacteria break down the food and turn nutrients into things our body can use. In addition, they keep a check on bad bacteria by multiplying themselves so often that the unhealthy kind do not have space to grow.

Digestion is an important process which provides your body with nutrients from foods and drinks to work properly and stay healthy. Digestive system breaks nutrients into parts which are small enough for your body to absorb and use for energy, growth and cell repair. However, we do not take enough care of our digestive system and ignore its health unknowingly. Here are a few major causes of an unhealthy digestive system:

Unhealthy diet: Eating processed food, junk food or a diet that comprises of high amount of carbohydrates, refined sugar, salt and fats can lead to unhealthy digestive system. This kind of food is low in nutrients, fibre and water content. Thus it slows down the digestion process making the stomach bloated. When food is absorbed by intestine, it requires fibre as well as water to excrete. But due to lack of these two contents, these foods lead to poor digestion and irritable bowel syndrome.

Overeating: Overeating slows down the digestive process. It means the food you eat will remain in the stomach for a longer period of time and be more likely to turn into fat. It can prevent your food from breaking down and digesting properly. Insufficient digestion will further result in various problems like heartburn and acid reflux, vomiting and nausea.

Insufficient water intake: Dehydration is one of the leading causes of unhealthy digestive system. It can lead to constipation, gastritis and acid reflux because the stomach does not have enough water to produce digestive acid. Studies have shown that drinking eight to 10 glasses of water a day can help limit the serious symptoms of acid reflux.

Lack of physical activity: If you do not exercise in your daily routine, the risk of harming your digestive system increases. Encourage walking, cycling, working out at gym, exercising at home, doing yoga, or any dance activity etc. in your daily routine. A regular exercise regimen can help treat constipation and promote healthy digestion.

Not giving your body the proper time to digest food that you have eaten before exercising: It is because if you have just eaten before exercising, you may suffer from heartburn, abdominal pain, vomiting and tiredness.

Lack of vegetables and fruits intake: If you eat less fruits and vegetables, your risk of suffering from constipation and other digestive ailments increases. Being high in dietary fibre and cellulose, fruits and vegetables prevent constipation, stimulate the gastrointestinal tract muscle and strengthen digestive system.

Lack of sleep: Not sleeping enough and sound may lead to gastroesophageal reflux disease, irritable bowel syndrome and functional dyspepsia. These all health issues are related to unhealthy digestive system. A poor sleep can negatively affect your gut microbiome, which can, in turn, lead to additional digestive and health issues.

Your overall health, including the health of your immune system depends upon good digestion. Neglecting your digestive system can cause major harm to your health. If your digestive system does not work properly, it will stress and overload your body. Incorporate a healthy regimen in your lifestyle to protect your digestive system.
