The Promise of 3D Printing in Healthcare

In healthcare, it’s the elusive breakthrough to a cure for diseases like cancer that has us all hoping. But sometimes it’s the bit-by-bit advancements, rarely getting headings, that make for greater impact. An example is the field of 3D printing, not even a medical technology by inception, but now a major disruptive force in the healthcare industry.

Also known as additive manufacturing, 3D printing allows the construction of physical objects based on three-dimensional digital models. A futuristic notion until recently, such printers are now commonly found in high schools, university libraries and labs, and also in a fabulous array of high-tech companies producing medical devices, and yes, body parts of all kinds.

Is It Safe to Have an Alcoholic Drink Before Dinner?

No one in our family has ever needed to cling to a telephone pole on the way home after drinking too much alcohol. Rather, we have long held that moderate amounts of alcohol can be healthy. But are we right? Now, a new Canadian report claims more than one or two drinks a week increases the risk of health problems, such as heart disease, stroke and cancer.

Professor Dan Malleck of Brock University, who specializes in alcohol regulation, and who has written several books on this topic, is skeptical of these generalized guidelines. He says they remind him of the Temperance Movement of long ago. Moreover, he states, the study used relative rather than absolute risk. This means that just three ounces and a half of alcohol shockingly increases the risk of larynx cancer by nearly 100 per cent! But this cancer is known to be primarily related to the smoking of tobacco.

Magic Mushrooms Are Moving Mainstream

You may have preconceived ideas that magic mushrooms are the party drugs of days past. However, in Canada and other countries, regulations are starting to ease on these prohibited psychedelics. The impetus stems from clinical trials showing remarkable results in treating post-traumatic stress disorder (PTSD) and treatment-resistant depression. The question begs, when should you plan for a mind-altering trip? "Magic mushrooms" grow naturally in many parts of the world. They contain psilocybin, which produces hallucinogenic effects when eaten.

Edema Is a Common Problem Often Ignored

What is one of the most common health problems that develops in people as they age, and also one of the least discussed? The answer is chronic swelling of the legs. At best, it’s a natural consequence of aging. But also known as peripheral edema, there can be medical, nutritional, or lifestyle causes and serious health consequences. Edema is a general term meaning swelling. Peripheral edema occurs in the legs, ankles, feet, as well as arms and hands. Swelling in other parts of the body include pulmonary edema (in the lungs), cerebral edema (in the brain), and macular edema (in the eye). It’s a medical emergency when the lungs or brain are affected, and a life-altering condition when vision is impacted.

Aging Well at Home

It’s been said that parents should be nice to their children. “After all, they are going to choose your nursing home.” So it is punishment or reward when children choose to help their parents stay living in their own homes? Some lifestyle choices are clear as night and day. Don’t smoke. Do exercise. Don’t lose sleep. Do eat a nutritious diet. But there is no clear answer to the question of where it is best to live out the senior years of life, with significant consequences for everyone in the family. Factors affecting in the decision are plentiful. Healthcare needs and cost of care. Housing suitability and safety considerations. Family location and friend groups. Availability of transportation and other services. And there’s no mistaking that as one gets older, these factors change in unpredictable ways.

Think Twice Before Shoveling the Snow

What should we conclude when health experts say people over 45 should not shovel snow? That’s a young age! What could be so threatening about clearing the snow to people in the prime of life? A winter storm may inspire some to curl up under a blanket. But for others, it’s a call to arms. Driveways must be cleared. Sidewalks too. And there’s no point in doing only half the job.

All Stuffed Up for the Holidays

There’s a lot of “stuff” this time of year – the stuffing in the turkey, for example, or all the meaningless commercial stuff we buy for the holidays that ends up in landfills. The holidays are a good time to look around and assess what is good stuff and what is bad. It might disappoint some readers to learn that this week the “stuff” we are choosing to look at is the mucus in your nose. There can be quite a volume of this sticky, or runny, or plugged up stuff at this time of year. A very stuffed up nose can be symptom of trouble. Our thoughts are with the many anxious families dealing with young children battling respiratory syncytial virus (RSV).

What A Dog’s Nose Knows

What a wonderful world if people could be as generous to humankind as dogs. Regardless of our faults, dogs provide unfailing loving care. A new study suggests dogs may be able to use their sniffing powers to know when someone is having a really bad day. Who knew there is an aroma to being stressed, but dogs seem to detect it. In this, they have a huge advantage over humans. The nose of a dog has 220 million smell cells compared to a meagre 5 million in humans.

Sarcopenia, Not Cancer, But a Deadly Word

Can you improve muscle mass even as you age? As Mickey Mantle, star player of the New York Yankees, remarked, “If I knew I was going to live this long, I’d have taken better care of myself.” Such is my worry in my 99th year. I was recently having more difficulty getting up from chairs and recalling patients who admitted they could no longer stand up from the toilet seat. They had slowly developed “sarcopenia”, weakened muscles from aging that robs one’s independence. Sarcopenia begins at about age 45 and causes skeletal muscle mass and strength decline at a rate of about one percent a year. By age 65, people who spend most of their time inactive on the sofa watching television have lost half of their muscle tissue! Losing muscle mass equates to getting weaker.

What Have We Learned in 30 Years?

This week entails a visit to the Gifford-Jones archives. What follows is an excerpt from a column on diabetes published thirty years ago. What has changed in society? You be the judge. November 1992:

Diabetes results from an abnormal handling of food by the body. Normally some food is converted into a sugar called glucose. This stimulates the secretion of the hormone, insulin, which acts as a "key" to allow glucose to enter the cells. Glucose is then used as "fuel" to provide energy.

Game On for Video Games

Wandering poorly prepared into a discussion about video games is ill-advised. Yet, people who don’t play video games commonly argue that long hours spent focused on digital playthings, especially by children, rot their brains. It is an uninformed point of view. There are plentiful misconceptions about video games. That label itself is outdated. Video games have evolved in many different directions and “gamification” is rapidly becoming part of the most important aspects of society, from education and healthcare to banking and retail.

Poor Sleep Can Lead to Inflammatory Problems

An old Irish proverb says, “A good laugh and a long sleep are the best cures in the doctor’s book.” But research suggests it would be wiser to think of good sleep as an ingredient of wellbeing – a starting point for health, not a fixer-upper. Sleep is an essential building block of good health, along with quality nutrition, moderate exercise, socioeconomic connectivity, mindfulness, and ample good luck.

Bright Promise for the Dark Disease of Glaucoma

Beware the “silent thief of sight”. Glaucoma sneaks up on people causing irreparable vision loss before diagnosis. Over 3 million North Americans have glaucoma – about half don’t know it. For society, the economic and social consequences of stolen sight is large. For sufferers, when glaucoma progresses to blindness, it is life changing. But is a cure in sight? The field of stem cell research is moving at lighting speed. In the search for a cure to glaucoma, adult stem cells, as opposed to the more controversial embryonic stem cells, are the focus. There are two types of adult stems cells. One type comes from tissues such as the brain, skin, or bone marrow. This type only makes more of the same. A stem cell from the liver only makes more liver cells.

The Right Omega-3 Reduces Risk of Heart Disease

How many readers still neglect to reduce their risk of heart attack? Can’t cut the sugar and salt? Still addicted to tobacco? Must have those harmful fatty foods, and moderate exercise is just too tough? This column has been like a broken record repeating the same song for years. “If you keep going to hell, you will eventually get there.”

Loneliness Among Men

Loneliness is worse for health than obesity – as bad as smoking 15 cigarettes a day. It can increase the risk of death by 26 percent and of cognitive decline on the way. But a recent story on the Good News Network offered a heart-warming take on loneliness among older men. At 67 years of age, “Phillip Jackson moved back to England from Australia,” the story reads, “and immediately felt like a stray dog in his native town.” He may have felt out of place, but he should not have felt alone. There is an abundance of people who feel isolated, even when they are living in vibrant communities.

We Are Not Ready for AI

Artificial intelligence (AI) is transforming healthcare at an astounding pace. Vantage Market Research, an American firm specializing in emerging markets, estimates the global AI market in health will climb from US$6.6 billion in 2021 to US$95.7 billion by 2028. That’s an astounding 46.1% compound annual growth. What’s does this mean for the healthcare consumer? Henry Ford advised, “Before everything else, getting ready is the secret to success.” He lived in a different time, when his assembly lines operated in a simple operational sequence, one workstation after another. Today, getting ready for anything doesn’t seem to be an option. In healthcare, the pace at which AI technologies are reshaping the sector is both exciting and inscrutable.

Rake Up the Leaves this Fall

What’s the most absurd image of healthy living? It’s a picture of a young woman using a leaf blower to clean up leaves in her yard while wearing ear protection, eye protection, and a mask covering her nose and mouth. The only thing that makes good sense is the mask. It’s the leaf blower that is most offensive. The first offense is the condoning of laziness. A leaf blower nearly eliminates the physical effort needed to clean up the leaves. In the past, we may have looked upon this as a good thing. Less work equals better life. False!

A Different Kind of Sickness

It’s a despicable human who preys on people to defraud them of money. What kind of sickness drives a person to such lows? It’s a sad fact that every year, millions of seniors fall victim to fraud. They are prime targets because they tend be trusting, have savings and good credit, and struggle to identify scoundrels posing as government agencies, tech support, repair people, or even family members.

Constipation Causes More Trouble Than You Think

Now and again, friends confide in friends that they have big problems. Dreaded are the occasions when the problem is a serious medical diagnosis. But when the problem is persistent constipation, it’s better to air the issue and not suffer in silence. Drug store remedies for constipation can fail to have effect. For many sufferers, the ailment involves days without a bowel movement. Ignoring the problem can lead to disturbing complications, to be avoided at all costs.

A Windfall of Science on Apples

We write about natural remedies we believe are good for human health. Why this focus? It’s not to encourage avoidance of pharmaceutical drugs when medical care is an imperative. To the contrary, Canadians and Americans have the luxury of the world’s best doctors, medicinal drugs, and healthcare facilities. But health systems are overwhelmed. To ease the crush, people who are not yet ill should take up responsibility to stay healthy.
