The skeptical cardiologist periodically updates the “header image” for this blog, typically uploading an iPhone “pani” of somethinng he considers beautiful, cool or quirky from one of his travels.
I can’t recall any comments on the header images so I had presumed that nobody really cares what is up there.
However, for my last header image (which at the time of this writing should still be above) I used a picture from my recent trip to Ecuador.
After returning from the Galapagos we drove north from Quito for 4 hours to Quilotoa and took the picture that is the current header image.
Quilotoa (Spanish pronunciation: [kiloˈto.a]) is a water-filled caldera and the most western volcano in the EcuadorianAndes. The 3-kilometre (2 mi)-wide caldera was formed by the collapse of this dacite volcano following a catastrophic VEI-6 eruption about 600 years ago.
A reader, commenting on my aspirin post, added the following cryptic words:
Also, I would be (very) interested to know about your ‘attachment’ / interest in Chang Bai Shan (‘Great White Mountain’ on the border of China / N Korea; one of the world’s largest stratovolcanoes)??? FWIW, we have(nick-)named one of our grandchildren (boy) with this name. My wife is Chinese/Taiwanese; my daughter has lived for 15? years in Beijing… All speak Mandarin (& English)…
I had no idea what he was talking about until I googled chang bai shan and looked at this image of “Heavenly Lake” which looks remarkably similar to the view we had over the Lagoon inside Quilotoa.
“Changbaishan Nature Reserve is the largest reserve in China, covering over 850 square miles. The rocks of Changbaishan supposedly have a white shimmer, giving the area its name (changbai means “ever white” in Chinese). The vast reserve comprises a collection of craggy peaks encircling Heavenly Lake, which occupies the crater of a long dormant volcano.”
This Chinese tourism site notes that a third of the Heavenly Lake lies in North Korea ” and its environs are considered sacred by both the Chinese and North Koreans; in Korean the area is known as Paektusan, and the North Korean leader Kim Jong Il claimed it as his “birthplace”. The imperial Qing dynasty, a Manchu family, revered Changbaishan as a holy land and the cradle of the Manchurian race.”
Despite the attraction of seeing the birthplace of Little Rocket Man, I have decided not to put Changbaishan on my bucket list because
Heavenly Lake’s cross-border status demands careful hiking – as recently as 1998 a British tourist was incarcerated for a month in North Korea for accidentally stepping across the poorly demarcated international line.
N.B. One of our party (who shall remain eternally nameless) experienced symptoms likely related to the rapid ascent to 13000 feet.
Acute mountain sickness is the most common type of high-altitude illness and occurs in more than one-fourth of people traveling to above 3500 m (11 667 ft) and more than one-half of people traveling to above 6000 m (20 000 ft). Symptoms include headache, fatigue, poor appetite, nausea or vomiting, light-headedness, and sleep disturbances. Symptoms usually occur 6 to 12 hours after ascent and can range from mild to severe.
The experience was exhilarating, enlightening and enchanting (therefore exhausting) and at some point I shall edit a brief movie/slideshow and post it somewhere for those interested.
Until then, here’s a red-footed booby I encountered on the island of Genovesa where a veritable cornucopia of exotic birds feed, nest and fly about, seemingly unconcerned about human visitors.
Charles Darwin did not visit Genovesa and none of the boobies (blue or red-footed or otherwise) played a role in his Theory of Evolution to my knowledge. They are not endemic or unique to the Galapagos.
The Song Of the Flightless Cormorant
There are many endemic animal species in the Galapagos which likely influenced Darwin’s thinking. On the youngest island,
Fernandina, I encountered the flightless cormorant. The Galapagos cormorant is the only flightless cormorant in existence.
Evolutionary biologist Patricia Parker (who is the senior scientist at the St. Louis Zoo) appears to be the leading researcher on endemic Galapagos bird species. She collected blood from the Galapagos cormorants, searching for mutations that might explain their useless wings.
She and her fellow researchers discovered about a dozen mutated genes in the Galapagos cormorants known to trigger rare skeletal disorders in humans called ciliopathies, often characterized by misshapen skulls, short limbs, and small ribcages. Since Galapagos cormorants have short wings and an unusually small sternum, the researchers suspected this link was significant.
The Sexual Attractiveness of The Male Blue-footed Booby
The blue-footed booby (BFB) is more famous on the Galapagos, primarily because of its mating dance but also because of its fascinating bright blue feet. During the mating dance the male booby prominently displays his sexy feet.
A fascinating study published in 2006 suggests that the brighter the blueness of the male booby feet, the healthier he is and the more likely he is to hook up with a female booby.
When male boobies were food deprived their feet became duller and when re-fed fresh fish the blueness brightened within 48 hours.
Variation of dietary carotenoids induced comparable changes in cell-mediated immune function and foot colour, suggesting that carotenoid-pigmentation reveals the immunological state of individuals.
In a second experiment the researchers captured male BFBs after their female mate had laid a first egg and painted a dull blue make-up on the male BFB feet. The females “decreased the size of their second eggs, relative to the second egg of control females, when the feet of their mates were experimentally duller. Since brood reduction in this species is related to size differences between brood mates at hatching, by laying lighter second eggs females are facilitating brood reduction.”
Another study in 2011 found that damage to the DNA of sperm increases with the age of male blue‐footed boobies. Furthermore, like humans sexual attractiveness (foot colour) declines with age in the BFB and is correlated with sperm DNA damage. The authors speculated that. “By choosing attractive males, females might reduce the probability of their progeny bearing damaged DNA.”
I will leave discussions on the technique for acquiring BFB sperm and for applying make-up to their feet to less squeamish authors. In the meantime we can all rest easy with the knowledge that female BFBs like their human counterparts prefer youngish males with brightish blue suede shoes.
While stocking up on key items for our Galapagos cruise, the eternal fiancée of the skeptical cardiologist (EFOSC) bought an item that set off the skeptical cardiologist’s (extremely sensitive) BS detector.
Once I began looking into the seasickness treatment options and science I soon realized that the vast majority of OTC medications, patches and devices offered are snake oil.
There is one highly effective treatment which requires a prescription, one possibly effective OTC treatment which will likely put you to sleep, and one very slightly effective treatment which will also likely put you to sleep.
First let’s look at the totally bogus patch Jen purchased.
It calls itself a “motion sickness patch.” It is manufactured in China. (Somebody should put a tariff on this junk!)
It also carries the allure of being natural which people (mistakenly) assume means free of side effects.
Since most people have heard of an effective motion sickness patch, they naturally assume that this is legitimate.
It appears to be highly rated on Amazon with 80% of over a thousand reviewers giving it 4 or 5 stars. However, 10% of reviewers give it 1 star, usually commenting that the MQ patches were useless and were purchased as they were cheaper than the prescription patch that worked for them before.
And it is no surprise that it doesn’t work for many because the ingredients would not be expected to have any effect on motion sickness.
Yes, in these patches you get the added bonus of “etc.” in the formulation!
In case you needed more explanation of how this works, check out the bizarre “working theory” of the mysterious ingredient’s efficacy:
1. Adjust the control of the vagal nerve to gastrointestinal tract, inhibit the motility of the gastrointestinal, thus preventing nausea and vomiting.
2. By expanding the capillaries of the skin, to improve the microcirculation of body and increase the amount of oxygen to brain, thus comes to the effect of refreshing your brain.
All I can say about those who have experienced relief with this MQ nostrum is “the placebo force is strong with you!”
Similarly, most of the sites on the internet which promise to give you the top 10 products in a certain area I have found to be bogus. For example, the amazingly useless MQ motion sickness patch is ranked #5 on the “Best Reviews” Guide to Motion Sickness.
The second product the EFOSC purchased online was the oddly-named Bonine. Bonine is the brand name for meclizine, a first-generation antihistamine with anti-cholinergic properties which is often prescribed for benign positional vertigo.
There is not much evidence supporting meclizine for sea sickness but it is widely used owing to its accessibility and marketing. Like all first-generation antihistamines, it will make you drowsy. Before the second generation, non-sedating antihistamines were introduced, I would walk around in a zombie-like state when my allergies required an antihistamine.
Keep in mind you can get a prescription for 30 tablets of meclizine 25 mg for about 12$.
More evidence that the placebo force is particularly strong in the motion sickness world is the widespread marketing, sales and testimonials to “acupressure” devices.
The EFOSC suffers from car sickness and several years ago purchased something called the Sea Band.
Wrist bands like the Sea Band claim to reduce nausea and other symptoms of seasickness through stimulation of the “P6/Neiguan” acupuncture point by applying acupressure or electrical acustimulation.
These work primarily through placebo effect and studies have shown a “sham” acupressure band works as well as a real one.
One fascinating study examined a self-fulfilling prophecy (SFP) approach to combating seasickness:
the authors experimentally augmented the self-efficacy of naval cadets by telling them that they were unlikely to experience seasickness and that, if they did, it was unlikely to affect their performance at sea. Naval cadets (N = 25) in the Israel Defense Forces were randomly assigned to experimental and control conditions. At the end of a 5-day training cruise, experimental cadets reported less seasickness and were rated as better performers by naive training officers than were the control cadets
The EFOSC is gravely concerned about debilitating seasickness during our 8 days on the Samba. To maximize the placebo force in her I should have emphasized how well the Sea Band and the MQ patch work. Hopefully she won’t read this post.
In Part 2 of the Best Seasickness Treatment I’ll discuss transdermal scopolamine and dramamine, the treatments with the best evidence for efficacy, safety and tolerability.
I’ll also examine the evidence for ginger.
What’s been your experience with sea sickness and treatments for sea sickness?
In preparation for our Voyage of the Samba in the Galapagos Islands I’ve been reading the chapter of Darwin’s Voyage of the Beagle that describes his 31 days in the archipelago.
Darwin felt the reptiles of the Galapagos gave the “most striking character to the zoology ” of the islands. He spends considerable time in his diary describing the creatures for whom the Spaniards named the islands. the giant tortoises.
A Galapagos giant tortoise can weight up to 600 pounds and live up to 150 years. A distinct species of tortoise developed on each separate island, adapting to differing environments.
On Charles Island (now Floreana) Darwin encountered the slowly
lumbering (4 miles per day) tortoises when they traveled to the central highlands to fill themselves with water. Prior to encountering humans the tortoises had had no natural predators and both the natives and the crews of whaling ships feasted on their easily obtained meat.
“the staple article of animal food is supplied by the tortoises. Their numbers have of course been greatly reduced in this island, but the people yet count on two days’ hunting giving them food for the rest of the week. It is said that formerly single vessels have taken away as many as seven hundred, and that the ship’s company of a frigate some years since brought down in one day two hundred tortoises to the beach.”
Natives savored both tortoise flesh and tortoise oil:
The flesh of this animal is largely employed, both fresh and salted; and a beautifully clear oil is prepared from the fat. When a tortoise is caught, the man makes a slit in the skin near its tail, so as to see inside its body, whether the fat under the dorsal plate is thick. If it is not, the animal is liberated and it is said to recover soon from this strange operation. In order to secure the tortoise, it is not sufficient to turn them”
Darwin also partook of tortoise:
“While staying in this upper region, we lived entirely upon tortoise-meat: the breast-plate roasted (as the Gauchos do carne con cuero), with the flesh on it, is very good; and the young tortoises make excellent soup; but otherwise the meat to my taste is indifferent.”
I’m pretty certain the passengers on the Samba will not be consuming any Giant tortoise meat this August but we will definitely encounter some of the surviving species on special farms and I will be listening for bellowing males:
During the breeding season, when the male and female are together, the male utters a hoarse roar or bellowing, which, it is said, can be heard at the distance of more than a hundred yards. The female never uses her voice, and the male only at these times; so that when the people hear this noise, they know that the two are together”
Perhaps I will be allowed to startle or ride a tortoise in the manner of Darwin:
“The inhabitants believe that these animals are absolutely deaf; certainly they do not overhear a person walking close behind them. I was always amused when overtaking one of these great monsters, as it was quietly pacing along, to see how suddenly, the instant I passed, it would draw in its head and legs, and uttering a deep hiss fall to the ground with a heavy sound, as if struck dead. I frequently got on their backs, and then giving a few raps on the hinder part of their shells, they would rise up and walk away; — but I found it very difficult to keep my balance.
Drinking FromThe Pericardium Of The Giant Tortoise
Finally, as this is a cardiology-oriented site I must take note of the following peculiar Darwinian observation:
“I believe it is well ascertained, that the bladder of the frog acts as a reservoir for the moisture necessary to its existence: such seems to be the case with the tortoise. For some time after a visit to the springs, their urinary bladders are distended with fluid, which is said gradually to decrease in volume, and to become less pure. The inhabitants, when walking in the lower district, and overcome with thirst, often take advantage of this circumstance, and drink the contents of the bladder if full: in one I saw killed, the fluid was quite limpid, and had only a very slightly bitter taste. The inhabitants, however, always first drink the water in the pericardium, which is described as being best.”
The pericardium is the sac around the heart. I am very familiar with the pericardium in humans as I look at it on every one of the many echocardiograms I read. Normally, it has only a very tiny bit of fluid in it, enough to lubricate the heart as it contracts and relaxes.
Thus, in a normal giant tortoise one would not expect more than an ounce of liquid in the pericardium-hardly worth butchering an ancient kind beast.
In the video below one can see a small to moderate sized pericardial effusion (the black crescent on the left of the heart) which corresponds to about 90 ml or 3 ounces.
I asked Jim Scharff, a cardiothoracic surgeon,who slices open the pericardium of humans on a daily basis what he typically encounters when the sac is opened. The question I texted him was:
“When you open the pericardium of someone without pericardial disease or effusion how much fluid do you typically encounter and what does it taste and look like?”
He responded “Usually 15-20 mL of serous looking fluid. I have no idea what it tastes like but it does not have any odor.”
Serous means ” typically pale yellow and transparent” and limpid, Darwin’s term, means transparent and clear.
Some diseases cause inflammation of the pericardium (pericarditis) and with this fluid (pericardial effusion) can build up in the pericardial sac. Large pericardial effusions compress the heart, impeding blood from entering it, and can cause shock and death (tamponade).
Pericardial effusions due to inflammation typically are not limpid as they contain blood cells and protein from the inflammation of the pericardium.
If the inhabitants were sometimes encountering significant amounts of tasty, yet limpid fluid in the pericardial sac of the giant tortoises was this normal or did it indicate the turtles had pericardial disease?
I was unable to find any indication that giant tortoises suffer unduly from pericardial disease but I did encounter one study which utilized ultrasound to document a pericardial effusion in an 80 year old spur-thighed tortoise which was suffering from pneumonia.
Consequently, I’m looking into taking a portable ultrasound device to take with me to the Galapagos to examine the hearts of the giant tortoises and answer once and for all the mystery of the giant tortoise pericardial fluid.
In August, the skeptical cardiologist and his eternal fiancée (and our friends Dave and Barb) will be visiting the Galapagos Islands on the 78 foot yacht, the Samba.
I’ve long wanted to visit this archipelago with its fascinating geographic and biologic features and its connection with Charles Darwin.
Darwin, born in 1809, was the son of a successful Shropshire physician and financier. By the age of 8, he writes in his Autobiography, “my taste for natural history, and more especially for collecting, was well developed. I tried to make out the names of plants and collected all sorts of things, shells, seals, franks, coins, and minerals. The passion for collecting, which leads a man to be a systematic naturalist, a virtuoso or a miser, was very strong in me, and was clearly innate, as none of my sisters or brother ever had this taste.”
After 2 years of studying medicine at Edinburgh University, Darwin writes, “my father perceived or he heard from my sisters, that I did not like the thought of being a physician, so he proposed that I should become a clergyman.”
In the course of obtaining the undergraduate degree needed to join the ministry, Darwin developed a passionate interest in natural history, and two books in particular, instilled in him the desire to be a scientist:
During my last year at Cambridge I read with care and profound interest Humboldt’s Personal Narrative. This work and Sir J. Herschel’s Introduction to the Study of Natural Philosophy stirred up in me a burning zeal to add even the most humble contribution to the noble structure of Natural Science.
After graduating Cambridge, Darwin, being recognized as “a young man of promising ability, extremely fond of geology, and indeed all branches of natural history,” was offered a position on a ship destined for a 5 year voyage around the world. This would profoundly influence his life and mankind’s vision of its origin.
The Voyage of the Beagle
In preparation for my visit to the Galapagos and our voyage on the Samba, I have been reading (from a free digital download) Darwin’s account of that historic voyage: “The Voyage of the Beagle” (originally entitled “Journal of researches into the natural history and geology of the countries visited during the voyage of HMS Beagle round the world,” published in 1839), which Darwin introduces thusly:
HIS MAJESTY’S ship, Beagle, under the command of Captain FitzRoy, was commissioned in July, 1831, for the purpose of surveying the southern parts of America, and afterwards of circumnavigating the world. In consequence of Captain FitzRoy having expressed a desire that some scientific person should be on board, and having offered to give up part of his own accommodations, I volunteered my services; and through the kindness of the hydrographer, Captain Beaufort, my appointment received the sanction of the Admiralty.
The Beagle was only 12 feet longer than the Samba motored sailing boat that we, along with 12 other adventurous passengers, 5 crew men and a guide, have selected for our Galapagos tour. However, Darwin’s vessel carried, in addition to Fitzroy and Darwin, 71 other passengers (whose names you can ponder here).
The Beagle Sets Sail
On the 27th of December, 1831, the Beagle sailed from Devonport with the object of completing:
“the survey of Patagonia and Tierra del Fuego, commenced under Captain King in 1826 to 1830, — to survey the shores of Chile, Peru, and of some islands in the Pacific — and to carry a chain of chronometrical measurements round the World. ”
The Beagle spent four years surveying the east coast of South American and didn’t reach the Galapagos until the fall of 1835, nearly 4 years after its launch. Darwin describes the islands as follows:
“SEPTEMBER 15th. — This archipelago consists of ten principal islands, of which five exceed the others in size. They are situated under the Equator, and between five and six hundred miles westward of the coast of America. They are all formed of volcanic rocks; a few fragments of granite curiously glazed and altered by the heat, can hardly be considered as an exception.
Darwin disembarked on San Cristóbal (September 17-22), Floreana (Charles)(September 24-27), Isabela (Albemarle)(September 29-October 2) and Santiago (James)(October 8-17).
FitzRoy and his officers developed updated charts of the archipelago, while Darwin collected geological and biological specimens on the islands.
(Our voyage below, visits the northwestern Galapagos, islands crossing paths with Darwin when we land in Isabella and Floreana
The Giant Tortoises of the Galapagos Islands
Darwin learned much on his voyage, not just about the geology and biology of the islands, but also about himself and the importance of reason and observation:
I discovered, though unconsciously and insensibly, that the pleasure of observing and reasoning was a much higher one than that of skill and sport. The primeval instincts of the barbarian slowly yielded to the acquired tastes of the civilized man.
Apparently his acutely observant father identified these changes in thinking just by looking at Charles:
That my mind became developed through my pursuits during the voyage, is rendered probable by a remark made by my father, who was the most acute observer whom I ever saw, of a sceptical disposition, and far from being a believer in phrenology; for on first seeing me after the voyage, he turned round to my sisters and exclaimed, “Why, the shape of his head is quite altered.”
So, dear friends and patients, pay close attention to the shape of my head upon my return from the Voyage of the Samba. You might assume the large occipital protuberance is a result of a nasty fall from the top of a giant tortoise when, in fact, it is the outward representation of all the brilliant observations and dangerous ideas I have acquired on my trip.
N.B. Of the many observations that Darwin made while he was on the Galapagos Islands, I found his comments on the pericardium of the giant tortoises the most intriguing. My next post on Darwin and the Galapagos will explore in detail this fascinating cardiologic observation.
The Skeptical Cardiologist and his eternal fiancee’ recently spent 5 days in the Netherlands trying to understand why the Dutch are so happy and heart healthy.
We were driven by Geo (former statin fence-sitter) from Bruges to Haarlem, a city of 150,000, which lies about 15 km west of Amsterdam and about 5 km east of the North Sea.
Haarlem is one of the most delightful towns I’ve ever stayed in.
I was struck by the beauty of its architecture, its canals and the happiness, height and friendliness of its inhabitants.
I was lucky enough to have a bike at my disposal. One day I set off randomly, and after 20 minutes of riding on delightfully demarcated bike lanes, I scrambled up a sand dune and looked out at the North Sea.
Just down the road was the beach resort of Zandvoort, where one can enjoy sunbathing, surfing or a fine meal while gazing at a glorious sunset.
Like Amsterdam, which is a 15 minute train ride away, bikes and biking abound in Haarlem, but unlike Amsterdamers, the Haarlemers were universally engaging, polite and friendly. Everything and everyone seemed clean, well-organized, relaxed and pretty…and, well, …happy.
The Dutch High Happiness Rating
The World Happiness Report 2017, which ranks 155 countries by their happiness levels, was released in March of this year at the United Nations at an event celebrating The International Day of Happiness.
The report notes that:
Increasingly, happiness is considered to be the proper measure of social progress and the goal of public policy
Norway was at the top of the happiness list but
All of the other countries in the top ten also have high values in all six of the key variables used to explain happiness differences among countries and through time – income, healthy life expectancy, having someone to count on in times of trouble, generosity, freedom and trust, with the latter measured by the absence of corruption in business and government.
The top 4 were closely bunched with Finland in 5th place, followed by the Netherlands, Canada, New Zealand, and Australia and Sweden all tied for the 9th position.
Despite the immense wealth of Americans, the report notes:
The USA is a story of reduced happiness. In 2007 the USA ranked 3rd among the OECD countries; in 2016 it came 19th. The reasons are declining social support and increased corruption and it is these same factors that explain why the Nordic countries do so much better.
Dutch children seem to be especially happy.
A UNICEF report from 2013 found that Dutch children were the happiest of the world’s 29 richest industrialized countries. America ranked 26th, barely beating out Lithuania and Latvia.
Cardiovascular Disease in The Netherlands
Ischemic heart disease (IHD) deaths are due to blockages in the coronary arteries. Typically, this comes from the build up of atherosclerotic plaques in the arterial system and in most countries heart attacks from this process are the major cause of death.
The Netherlands has the third lowest rate of IHD deaths in developed countries, only slightly higher than France and less than half the rate of the USA.
In all developed countries over the last thirty years we have seen a marked drop in deaths due to IHD. In The Netherlands it has dropped 70% and the rate in 2013 was nearly as low as France’s rate.
In addition, the Netherlands has a very low rate of deaths from hypertensive heart disease. This table from 2008 shows that they are second only to Japan and their mortality rate is a third of that in the US.
The current Dutch age-standardised mortality from circulatory disease is 147 per 100,000, and only Spain and France have lower cardiovascular mortality rates (143 and 126 per 100,000, respectively). In all other European countries, including for instance Switzerland and Greece, cardiovascular mortality is higher .
What factors could be causing all this happiness and heart healthiness?
The Seemingly Horrid Dutch Diet
We have been programmed to believe that heart attack rates are related to saturated fat in our diets.
The fact that the French consume lots of saturated fat and rank so low in IHD deaths has been called the French Paradox as it seems to contradict the expected association.
One thing is clear-the Dutch are not following a whole foods, plant-based diet. They are among the world leaders in consumption of both fat and sugar as the graph below indicates.
The recommendation to eat fish at least twice a week, of which at least once fatty fish such as salmon, herring or mackerel, is followed by a mere 14 percent of the population. Less than 25% of them meet the recommended daily amount of fish, fruit, and vegetable consumption.
They do catch and export a lot of fish and shellfish and are in the top 10 of seafood exporting countries (99% of all those mussels consumed in Belgium come from The Netherlands).
And, to my great surprise, they eat lots of French, or as I have started calling them, Flanders fries.
I personally witnessed massive amounts of cheese and butter consumption.
In fact, the Dutch average 15% of calories from saturated fat, which is far above the 10% recommended by the Dietary Guidelines for Americans.
The mean baseline intake of total saturated fatty acids (SFAs) in the population was 15.0% of energy. More than 97% of the population exceeded the upper intake limit of 10% of energy/d as recommended by the Health Council of the Netherlands.
The Dutch weren’t eating so-called healthy fats as “The main food sources of SFAs were cheese (17.4%), milk and milk products (16.6%), meat (17.5%), hard and solid fats (8.6%), and butter (7.3%).”
Surprisingly, the more saturated fat the Dutch consumed, the LOWER their risk of death from IHD:
After multivariable adjustment for lifestyle and dietary factors (model 4), a higher intake of energy from SFAs was significantly associated with a 17% lower IHD risk (HR per 5% of energy: 0.83; 95% CI: 0.74, 0.93)
The Dutch Paradox
Data shows that the Dutch are eating lots of saturated fat from dairy and meat, but it appears to be lowering their risk for heart attacks
Yes, despite 40 years of high saturated fat consumption, the Dutch have seen a 70% drop in mortality from heart attacks. Their rate of dying from ischemic heart disease is lower than the US and only slightly higher than the French.
Thus, rather than talk about a French paradox, we should be talking about the Dutch paradox.
For the French paradox many theories, both fanciful and serious, have been proposed
The one most laypeople remember (due to a 60 Minutes episode in 1991) is that the French are protected by their high red wine consumption. Although this theory proved a great boon to the red wine industry (sales rose 40% the year after Morley Safer made his presentation on 60 Minutes), it has never had any serious scientific credibility. Current thinking is that all forms of alcohol in moderation are equally protective.
Others have proposed garlic or onion or faux gras consumption. My own theory for the French is that it is fine cheese and chocolate consumption that protects them.
In subsequent posts I’ll lay out the evidence for my startling new theory to explain the Dutch paradox.
The skeptical cardiologist is about to embark on a two week vacation in Europe.
I and my Eternal Fiancee’ will fly into Paris and spend a few days there lapping up the Parisian food, booze and ambiance. Then we will take a train from Paris to Bruges, Belgium for another few days of sight-seeing.
The tour will end in Haarlem, The Netherlands (aka Holland) where the Eternal Fiancee’s parents (Wendy and Geo of “Are you on the fence about statin drugs ” fame) have swapped their house (and car) in Annapolis, Maryland (temporarily) for a house in Haarlem (and car and bikes!).
For a cardiologist, a two week vacation in Europe used to mean severing almost all communication with one’s practice. I can recall my first visit to France in 1987; there was no internet, no cell phone and no text messaging. A several minute phone call to talk to my children seemed prohibitively expensive.
For this trip, however, I am loaded up with a laptop, a cell phone and an ipad, anticipating the ability to stay in communication with everyone, everywhere.
This super-communicative status means I could do a whole lot of patient care on this European Vacation.
If I wanted to, I could log in to my hospital’s EHR and check on my patients. I could see what their latest blood pressure and weight was, or how low their potassium had dropped after diuretics. I could write orders to lower their diuretic dosage or for additional potassium.
For my outpatients, I could check labs results and send them messages. I could stop blood thinners prior to surgery or advise those having questions or problems.
If my patients have had diagnostic imaging studies, I could remotely read and report echocardiograms, nuclear stress tests, long term monitors, coronary calcium and CT angiograms.
In short, I could continue to keep an eye on my practice even while trying to vacation thousands of miles away.
Fortunately, I have an outstanding partner in my practice, Dr. Scott Brodarick and a wonderful medical assistant, Jenny Clancy, who will be covering me and handling the low potassiums and the surgical clearances and all the myriad unforeseen patient developments, making it possible for me to focus on being a skeptical tourist rather than a clinical cardiologist for two weeks.
