Mediclim Forecasts help reduce sickness related absenteeism from work
Soumis par john bart le dim, 01/22/2012 - 17:47.We have taken care to position ourselves as a tool that can be used to reduce health related absenteeism from work. In the long run we know this can only benefit employees and employers.
Here is some background information that speaks to the value of our initiative:
REFLECTIONS.. the Pill, AIDS, mediclim, the internet and patient empowerment.
Soumis par john bart le lun, 01/02/2012 - 04:39.I qualified as a physician in 1969. That's a long time ago. I'm happy to say I'm still working as a family doc. It's great. I now treat the children of children I first met in 1973 when I moved to Toronto the Good and, really and truly, my job is its own reward.
But things have changed. Have they ever. For instance:
When I started out the sister on a ward was queen. If she said jump everyone, and I mean everyone, from professors of medicine to medical and nursing students, jumped. The only question was how high.
Are we worth our salt?
Soumis par john bart le dim, 11/27/2011 - 16:53.In times past salt was a commodity as precious as gold. Whole fortunes were made from the salt trade and at least one city, Salzburg in Germany, owes its name and early prosperity to it.
circadian rhythms in the human body.
Soumis par john bart le dim, 10/23/2011 - 20:38.I thought you might like to know what the results of circadian rhythms are on our bodies, so here goes.
0200 our deepest sleep
0430 our lowest body temperature
0645 the sharpest rise in our blood pressure
0730 Melatonin secretion stops
0830 bowel movement likely
0900 highest testosterone secretion in males
1430 best coordination
1530 fastest reaction time
1700 greatest cardiovascular efficiency and muscle strength
1830 highest blood pressure
1900 highest body temperature
2100 Melatonin secretion starts
2230 bowel movements suppressed
2400 coach turns into a pumpkin
GM foods---food as a drug---food as a poison.
Soumis par john bart le mer, 10/12/2011 - 21:06.I've been a family doc for 40 years. Among the things I've learnt is the strong belief that a person's lifestyle is the most important determinant of his or her longevity and good health.
What does lifestyle mean? In the context of the developed world it means what you eat, how much you exercise and how much stress you can handle over and above the routine amount to get you up and at 'em each day.
How sunlight affects the way the body treats medicines
Soumis par john bart le ven, 09/30/2011 - 19:19.Check this out! Vitamin D, which is produced by the skin on sunny days (20,000 units in half an hour if you sit in the sun in a bathing suit) boosts the expression of a gene for the liver enzyme CYP3A4... for the untechnical this means more Vit D is produced.
This enzyme metabolizes over half the drugs we use. The more the gene is boosted, the more of CYP3A4 there is, the quicker medications are metabolized, which results in less of the drug circulating in our blood stream... and so less is available to do what we want.
Radioactive Iodine, the thyroid gland and what happens to people at a distance from a nuclear reactor (think Japan, Chernobyl)
Soumis par john bart le mer, 08/31/2011 - 21:03.Radionucleotides such as radioactive iodine are released into the atmosphere after catastrophes like these. People can then ingest these particles in different ways... in aerosol form, from contaminated water, from vegetation (eat your greens or you'll get no pudding) dairy products (because cows feeding on Radioactive Iodine contaminated grass secrete it in their milk) or from meat (beef/pork/veal/lamb...).
Generic versus brand-name drugs.
Soumis par john bart le dim, 04/24/2011 - 23:00.Patients worry that generic drugs are not the equivalent of the original brand-name drugs which many of them were first given when the drug came on the market.
Well, it's hard to gainsay what people feel unless there are stats to say otherwise. There's a lot riding on this, for patients, physicians and drug companies. So what are the stats to date? Let's take different groups of drugs:
Beta Blockers.. in randomized controlled trials (the gold standard) clinical outcomes (=how did the patients do?) were NO better with brand names versus generics. (7 out of 7 clinical trials)
The skinny on sunscreens...how, what, when and why
Soumis par john bart le lun, 04/04/2011 - 11:48.HOW... sunscreens contain chemicals that block ultraviolet A and B rays from the sun. These photoage the skin and, as experience has shown, overexposure to them is associated with cancers of the skin...melanoma and squamous cell cancers. The wavelength of UVA1 is 340-400nm, UVA2 is 320-340nm and UVB is 290-320nm.
We measure sunscreens by their Sun Protection Factor... SPF... This represents the fraction of redness (erythematous) producing ultraviolet light that gets through to the skin after they've been applied.
