Dr Art Hister – Yet Another Reason to Exercise

A terrific talk on aging I heard a while ago pointed out something that I had never considered but which seems to be quite true, and it’s a very depressing thought.

This aging expert pointed out that although you often see pictures of a 70-year-old doing something quite amazing like climbing Mount Kilimanjaro, for example, but you never see an 85-year-old doing something similar.

That’s because, he said, of age-related frailty, meaning that we lose our muscle strength as we grow older.
Thus, it’s commonly said that we lose roughly 1 % of our muscle mass every year beyond the age of 40, and eventually – sometime between 75 and 85 for nearly all of us – we reach a tipping point of lost muscle mass when we can’t do so many – or even any – of the things we used to do so easily years before.

So the great news is that maybe that doesn’t have to happen.

In a study with terrifically hopeful possibilities, researchers at the University of Pittsburgh examined 40 competitive athletes – runners, cyclists, swimmers – between the ages of 40 and 81, and the researchers found that – quite to their surprise – that not only did those athletes have as much muscle tissue as people decades younger than them, they also remained nearly as strong as many people a couple of decades younger than them.

Now, clearly these were elite athletes and very few of us are able to train as much as these people do.

But this isn’t an all-or-none situation so seems to me that even some regular exercise can delay or postpone that heretofore seemingly inevitable frailty that the elderly suffer and which condemns so many seniors to having to give up their independence.

And honestly, doesn’t some exercise done a few times a week seem like a small price to pay for raising your chances to live a longer independent life down the line?

The Facts About Cholesterol

Cholesterol is an important substance in our bodies that, for the most part, occurs naturally. It helps our bodies make hormones, process vitamin D, build cells and create substances that help us digest food. Cholesterol can become dangerous, though, when the levels in our blood stream get too high.
Most of the cholesterol in our bodies—about 80%—is made by our liver. The other 20% comes from the foods we eat. A person can’t tell if his or her cholesterol levels are too high, as there aren’t any noticeable symptoms. To determine your cholesterol levels you need to have a blood test done by your doctor involving a tiny sample of blood.
The test will analyze the two main components of cholesterol—low-density lipoprotein (LDL) and high-density lipoprotein (HDL).
LDL is sometimes referred to as “bad” cholesterol, because at high levels it builds up and can block our arteries, preventing blood moving freely through our bodies. HDL is usually called “good” cholesterol, because its job is to carry excess cholesterol from other parts of our bodies, including the arteries, back to the liver. Not only does the liver produce cholesterol, it also removes it from our bodies.
Your doctor may also assess your triglyceride and C-reactive protein levels. These are other indicators found in your blood test that could signal an increased risk of heart attack or stroke.

Lowering Cholesterol

The first step is to make a lifestyle change, and a big part of lifestyle is eating a healthier diet. Here are some things you should reduce or avoid to maintain healthy cholesterol levels:
  • Saturated fats—These are found in animal-based foods such as meat and dairy products, and in some plant foods such as coconut oil, palm oil, and cocoa butter. Avoid or limit deli meats. Choose lean cuts of meat, or replace with fish and legumes (lentils, beans) instead.
  • Trans fats—These are a form of man-made fat that is created during a process called hydrogenation. This is where liquid oils are turned into solid fat (such as some margarines.) While technically unsaturated, these facts act like saturated fats and raise blood levels of LDL (“bad”) cholesterol. Choose oils high in mono-and polyunsaturated fats such as canola, corn, or soya oil. Use in moderation.
  • Avoid dairy products with high milk fat—choose 1% MF (milk fat) or cheeses with 15% MF or lower.
There are things you can add to or change in your diet which help the body eliminate excess blood cholesterol.
  • Soluble fibre—This is found in oat bran, fruits, and vegetables.
  • Unsaturated fats—These are found in vegetable oils, nuts, seeds, and fatty fish.
  • Cooking—More often than not, opt to broil, bake, poach, or even microwave food instead of frying.

Other tips to beat “bad” cholesterol

Keeping active and maintaining a healthy body weight will also help reduce cholesterol levels. And finally, quit smoking. It’s been found that tobacco reduces your level of HDL, “good” cholesterol, and raises your total blood cholesterol levels—which makes the perfect combination for increasing your total risk of having a heart attack.
If your doctor feels you need to be on cholesterol-lowering medication, it’s important to take it exactly as directed. For more information on cholesterol, or advice on making different lifestyle choices, come by the pharmacy and ask your London Drugs pharmacist.

Dr Art Hister – Watchful Waiting and Prostate Cancer

Yet another study (published in the Journal of Clinical Oncology) has concluded that for many cases of prostate cancer, “watchful waiting”, that is, doing nothing at all and just letting nature take its course, is as good a tactic as getting any of the most advanced therapies we have to offer.

In this study of 769 patients with a median age of 66 who had been diagnosed with the kind of prostate cancer that should not be overly aggressive (and remember, that’s the vast majority of prostate cancers), 1/3 of the men opted – as one would expect – for some kind of therapy, either radiation or surgery.

But 2/3 of these men opted for watchful waiting instead.

At the end of 10 years, the researchers concluded that doing nothing “caused no apparent harm,” meaning that the men who chose “watchful waiting” were just as likely to be alive and just as likely to not having had their malignancy spread as were the men who had opted for intervention.

Yet the key difference is that the no-treatment guys were way better off on average since they had clearly not suffered any side effects or complications from doing nothing as opposed to the men who had chosen radiation or surgery, both of which come with risks attached.

The bottom line: prostate cancer is very common but only kills or harms a small portion of the men who end up with that malignancy, especially if the men are over age 65, and although all of us are always eager to “treat” a cancer, sometimes that treatment should be “nothing”.

Preventable warns of the dangers of mixing medications during this flu season.

With the cooler weather and flu season upon us, the Community against Preventable Injuries (Preventable) is partnering up with London Drugs to raise awareness about the dangers of mixing medications and self-medicating.

Tragically, unintentional poisoning is among the top three causes of death and hospitalization in BC. In BC alone, hospital emergency departments treat an estimated 210,000 patients each year for adverse drug events.1 Drugs or medicinal agents are the predominant substances that result in poisoning deaths and hospitalizations, accounting for approximately 84 per cent. According to the BC Drug and Poison Information Centre (DPIC) data, the majority of calls were related to non-prescription (22.8 per cent) and prescription medications (22.2 per cent)2.

“No one expects to have a serious drug interaction or that mixing medications could lead to death…but it does happen,” says Dr. Ian Pike, spokesperson for Preventable. “The key to reducing preventable injuries including the unintentional mixing of medications is behaviours and attitudes. This fall, we’re pleased to partner with London Drugs again to raise awareness about the scope and magnitude of preventable injuries in this province, and to encourage people to have a word with themselves, and their pharmacists before self-medicating and mixing medications.”

As part of this Preventable campaign, signs will be placed in London Drugs stores across BC with the message “You’re not expecting mixing medications to make you feel worse.” In addition, Preventable will be airing 15-second television spots featuring London Drugs’ Vice President of Pharmacy, John Tse, with the same message. The television spots and signage will also be supported by a social media campaign to further help raise awareness about this important issue, and to encourage British Columbians to talk to their health care provider.

Preventable and London Drugs hope to make a difference by raising awareness and getting British Columbians to think differently about their current attitudes and behaviours toward preventable injuries.

London Drugs has provided a list of suggestions to help prevent people from mixing medications:

  • Provide your medication list to your doctor and pharmacist. Make certain it contains the herbal medications and OTC medications you are taking, since these may react with prescription medications.
  • Throw away old medications, and always keep medications in their original container.
  • Always read drug labels carefully.
  • Learn about the warnings for all the drugs you take.
  • Ask your doctor what you need to avoid when you are prescribed a new medication. Ask about food, beverages, dietary supplements, and other drugs.
  • Use one pharmacy for all of your drug needs.

Dr Art Hister – An Easy way to lower your risk of diabetes

Here’s an easy and very welcome way to lower your risk of diabetes: just sleep more.

More accurately, make sure to get just the right amount of good quality sleep.

At least that’s what a study published in the journal Diabetes Care found was the case for obese teenagers, and what’s true for those kids is very likely also true for other people as well, including even healthy adults.

In this study, researchers looked at 62 obese teenagers (average age 14) and they found that both “insufficient” and “excessive” sleep were linked to abnormal blood glucose levels (and too little sleep was also linked to abnormal insulin levels).

Why?

Probably because proper sleep helps regulate hormonal function, and one of the most important hormones, of course, is insulin.

That’s also why some experts believe that our obesity epidemic is partly a function of the lack of adequate sleep we are all suffering from these days.

Bottom line: good quality sleep is very important for good health (not just for weight control) so don’t cheat on your sleep.

 

Preventing Colds & Flu

As soon as children return to school, colds and other ‘back to school’ ills begin in earnest, quickly spreading to parents and older siblings, through workplaces and other communities.

The tendency to gather indoors during the colder months hastens the spread of viruses, culminating in the dreaded ‘flu season’ at the end of the year…

Although it’s hard to think of cold prevention during those warm September days that mark the end of summer, this is the time of year we need to get started on our prevention strategy for winter ills.

“Every year like clockwork, two weeks after kids go back to class, the cough and cold season starts with a bang,” says Dr. Alan Kaplan, Chairperson of the Family Physician Airways Group of Canada (FPAGC) and executive member of of the International Primary Care Respiratory Group (IPCRG).

“It’s no surprise that respiratory infections spike when people suddenly change their routines, diets and sleeping patterns – which makes them more susceptible to infection – and then gather together in small rooms for hours on end,” Dr. Kaplan explains. He references a research project on hygiene in schools, led by Dr. Charles Gerba, a professor of environmental microbiology, which found that 50% of the classroom surfaces examined were hosting some sort of virus.

“With those kinds of opportunities for transmission, it’s no wonder that, on average, 200,000 schooldays are missed because of illness in Canada every month,” says Dr. Kaplan.

How Viruses Spread
Of course, it’s not just young children who become sick shortly after school starts (although the closeness of little ones, and sharing behaviors – especially with food and drink – tend to get the viral ball rolling). Students of all ages bring home germs they’ve picked up in school, to share with their families. Family members then go on to share them with friends, coworkers and other members of their various communities.

“People infected with rhinovirus or influenza are contagious starting about 12 hours before they even start to feel any symptoms, making it very difficult to prevent spreading those viruses around,” says Dr. Kaplan.

The Best Prevention
The very best way to prevent colds and flu is to wash your hands often and teach your children to do the same. You should wash your hands before and after shopping trips (most supermarkets and drug stores now provide gel dispensers or wipes for this purpose), and always before eating/preparing food and after blowing your nose, or wiping your child’s. You can purchase hand santizers at London Drugs. Here are a few more pointers:

  • Remember to wash your hands after touching elevator buttons, keypads, public phones, doorknobs and stair rails.
  • Avoid handshakes whenever possible, and go wash your hands afterwards if you do greet someone this way. (Meet-and-greet events, cocktail parties and similar gatherings where food is offered are prime environments for viruses to spread.)
  • If someone coughs or sneezes near you, move quickly away and/or cover your nose and mouth. If you have a cough or cold, be sure to use a tissue or sneeze into the crook of your arm.
  • For adults and children over 12 years of age, consider taking an immune-supporting supplement like non-drowsy COLD-FX® or COLD-FX® Extra Capsules.COLD-FX® may be taken preventatively as well as to reduce the duration of a cold.
  • Be sure to attend to the basics of good health and a strong immune system: get a minimum seven hours of sleep nightly, be physically active every day, and eat lots of healthy fruits and vegetables, low-fat protein and whole grains.

Although there are no guaranteed ways to prevent catching a cold, with a strong prevention strategy, you increase your chances of staying healthy throughout the winter months.

Dr Art Hister – Keep Medications Away from Kids

A recent review of accidental poisonings among American kids under the age of 5 found that the rate of such poisonings has increased by 22 % from 2001 to 2008, the last year for which adequate data is available. This is a startlingly large increase given the fact that the number of kids in that age group has only increased by about 8% over the same time span.

Why have such poisonings risen so sharply?

Lots of reasons, but one stands out: there are just so many more medications out there and so many more of us are using at least one drug, and often, of course, several at a time.

Accidental use of drugs is a completely preventable problem, so if you have any kids in the house, or if any are ever likely to visit, be sure to put all your medications in a safe place that is very hard, if not impossible, for a young person to access.

And as a new grandparent myself, I make this special plea to other grandparents because that’s one special situation – a grandchild visiting a grandparent – where extra caution is often needed.
