The meta-analysis foundthat in patients getting 800 units of vitamin D and more than 1,000 mgof calcium a day, there was a 21% reduction in risk of fracturecompared to placebo.<br></blockquote>The new report was a <a title="Wikipedia link" href="http://en.wikipedia.org/wiki/Meta-analysis"><i>meta-analysis</i></a>,meaning that the authors pooled the results of several studies.&nbsp;As seen in Wikipedia:<br><blockquote>In <a href="http://en.wikipedia.org/wiki/Statistics" title="Statistics">statistics</a>, a <b>meta-analysis</b>combines the results of several studies that address a set of relatedresearch hypotheses. The first meta-analysis was performed by <a href="http://en.wikipedia.org/wiki/Karl_Pearson" title="Karl Pearson">Karl Pearson</a> in 1904, in anattempt to overcome the problem of reduced <a href="http://en.wikipedia.org/wiki/Statistical_power" title="Statistical power">statistical power</a> instudies with small sample sizes; analyzing the results from a groupof studies can allow more accurate data analysis.</blockquote>To give an idea of why the meta-analysis might be more valid than theother studies, the authors point out:<br><blockquote>For one thing, he said, neither study had enoughstatistical power to find an effect. For instance, he said, the RECORDtrial, looking at hip fractures, had 2,649 participants and only 93events. By contrast, Dr. Boonen said, he and his colleagues had apatient pool of 16,978 individuals and 812 fractures.<br></blockquote>I'm not sophisticated enough with statistics to be able to give anopinion of the validity of this particular analysis, and the report Iam citing here has not yet been subjected to peer review.&nbsp;Therefore, the results are to be considered to bepreliminary. &nbsp;<br><br>What is interesting is the list of reasons given, for why themeta-analysis gives results that are different than thepreviously-reported studies. &nbsp;It turns out that the positiveeffect is seen only in those patients who actually had a deficiency ofeither calcium or vitamin D. &nbsp;If the patient's regular dietprovides enough of those nutrients, there is no effect fromsupplements. &nbsp; Some patients in the studies did not take dosesthat were high enough. &nbsp;Some did not take both the calcium andthe vitamin D. &nbsp;Also, the prior reports included in theanalysis patients who did not actually take the supplements at all:<br><blockquote>Dr. Boonen told reporters after his presentation thatclinicians need to pay attention to four factors. They must prescribe acombination of calcium and vitamin D, the doses must be high enough,the patients must be in need of the supplements, and finally they mustactually take their medication.<br></blockquote>It seems kind of obvious to say that the patients actually have to takethe supplements in order to see an effect, but in daily practice, noncomplianceturns out to be a common problem. &nbsp;Sometimes the factors thatseem too obvious to even consider, are the ones that turn out to beimportant.</div></content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114974738938794238'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114974738938794238'/><link rel='alternate' type='text/html' href='http://corpus-callosum.blogspot.com/2006/06/they-must-actually-take-their.html' title='"They Must Actually Take Their Medication"'/><author><name>: Joseph j7uy5</name><uri>http://www.blogger.com/profile/12806669663107445151</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='//blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVJBzauYzPUXYT0CJ_mAitRBt8G2SDKkcSagvAIpSw_EcqJl25b8N1K8POIiJiWSnjyddZqzRGp4FbixU8DgRDf7TP7ZJuGSsKRZIM0DQbfGclkbqiZ1kNiJKeUs1ylA/s220/j7uy5.jpg'/></author></entry><entry><id>tag:blogger.com,1999:blog-6281085.post-114948416952699754</id><published>2006-06-05T01:09:00.000-04:00</published><updated>2006-06-05T01:09:29.560-04:00</updated><title type='text'>Is This One For Real?</title><content type='html'><div id="Science">The LA Times (free registration required) has an article on thepossibility of a shortage of physicians in the USA:<br><blockquote><b><a href="http://www.latimes.com/business/la-fi-doctors4jun04,0,1528090.story">PhysicianShortage Looms, Risking a Crisis, as Demand for Care Explodes</a></b><br> <b><small>An aging America needs more doctors, but supplyisn't keeping up. Experts fear worsening quality and dangerously longwaits for appointments.</small></b><br> <small>By Lisa Girion, Times Staff Writer<br>June 4, 2006</small><br> <br>A looming doctor shortage threatens to create a national healthcarecrisis by further limiting access to physicians, jeopardizing qualityand accelerating cost increases.<br> <br>Twelve states &mdash; including California, Texas and Florida&mdash; report some physician shortages now or expect them within afew years. Across the country, patients are experiencing or soon willface shortages in at least a dozen physician specialties, includingcardiology and radiology and several pediatric and surgicalsubspecialties.<br> <br>The shortages are putting pressure on medical schools to boostenrollment, and on lawmakers to lift a cap on funding for physiciantraining and to ease limits on immigration of foreign physicians, whoalready constitute 25% of the white-coated workforce.<br> <br>But it may be too late to head off havoc for at least the next decade,experts say, given the long lead time to train surgeons and otherspecialists. [...]<br></blockquote>The biggest issue there is the funding for medical training.&nbsp;It is incredibly expensive to train physicians. &nbsp;Irecall that when I was in medical school, and students were complainingabout double-digit increases in tuition, one of the administrators toldus that our tuition only covered about one-third of the actual cost oftraining. &nbsp;As an <a href="http://www.med.umich.edu/medschool/facts_faces/index.htm#tuition">historicalaside</a>:<br><blockquote><a href="http://www.flickr.com/photos/jyaroch/160615766/"><img alt="First UM Medical building" title="First UM Medical building" src="http://static.flickr.com/47/160615766_2a0812a0ef_o.jpg" align="right" border="0" height="86" width="120"></a>Whenthe Medical School first opened in 1850, students paid only a $10registration or matriculation fee.<br> <br>By 1891, the matriculation fee was $10 for Michigan residents and $25for students from out of state. Over the next 50 years, tuition roseslowly until it was $250 in 1940. In the early part of the twentiethcentury, students were required to pay laboratory and demonstrationfees totaling $136 over the four years. None of this takes into accountroom and board. The average cost of room and board in 1893 was $3-$5 aweek; 1931: $12-15 a week. In 2003, tuition and fees for Michiganresidents were $20,526 (out of state, $31,526) and estimated livingexpenses were $20,300 a year. Currently, the average student debt forsomeone receiving an M.D. degree from the University of Michigan isclose to $100,000. <br></blockquote>Medical schools are allowed to charge more for services, based upon therecognition of the fact that training costs are high. &nbsp;But thefederal government has balked at these higher fees, so there have beencaps. &nbsp;This debatable policy has made it more difficult formedical schools to expand enrollment.<br><br>There have been dire warnings of physician shortages before, but thistime it seems more credible to me. &nbsp;The key factor is the factthat the average age of the US population is increasing.&nbsp;Obviously, older people require more doctoring than youngerpeople. &nbsp;But there is another factor:<br><blockquote>At the same time, younger male physicians and women&mdash; who constitute half of all medical students &mdash; areless inclined to work the slavish hours that long typified theprofession. As a result, the next generation of physicians is expectedto be 10% less productive, Edward Salsberg, director of the Assn. ofAmerican Medical Colleges' Center for Workforce Studies, told acongressional committee in May.<br></blockquote>I expect that the trend toward fewer work hours will bring up somecontroversy, and possibly some resentment. &nbsp;Some physicianswill be negatively judgmental about those who choose to work fewerhours. &nbsp;Others will face pressures to delay their retirement.&nbsp;At the same time, it will be increasingly difficult forphysicians to keep up-to-date with their skills and knowledge base.&nbsp;Every hour spent on continuing education is an hour that isnot devoted to patient care. &nbsp;There is a risk that the demandfor more patient-care hours could lead to doctors devoting less time tocontinuing education, which obviously would have a detrimental effecton quality.<br><br>It seems likely that the prediction of a shortage of physicians isaccurate. &nbsp;That will pose new challenges for physicians, interms of managing stress. &nbsp;It occurs to me as I write this,that it may be desirable to make a point of educating medical studentsabout these pressures, and how to deal with them. &nbsp;As soon asI figure out how to deal with them, I will post that information here. </div></content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114948416952699754'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114948416952699754'/><link rel='alternate' type='text/html' href='http://corpus-callosum.blogspot.com/2006/06/is-this-one-for-real.html' title='Is This One For Real?'/><author><name>: Joseph j7uy5</name><uri>http://www.blogger.com/profile/12806669663107445151</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='//blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVJBzauYzPUXYT0CJ_mAitRBt8G2SDKkcSagvAIpSw_EcqJl25b8N1K8POIiJiWSnjyddZqzRGp4FbixU8DgRDf7TP7ZJuGSsKRZIM0DQbfGclkbqiZ1kNiJKeUs1ylA/s220/j7uy5.jpg'/></author></entry><entry><id>tag:blogger.com,1999:blog-6281085.post-114945540600864470</id><published>2006-06-04T17:01:00.000-04:00</published><updated>2006-06-04T17:14:42.266-04:00</updated><title type='text'>What To Do On 6/6/6</title><content type='html'>There is still time to make your plans:<blockquote><b><a href="http://www.suntimes.com/output/news/cst-nws-party04.html">Hell plans devil of a time on 6/6/06</a><br></b><br>June 4, 2006<br><br>HELL, Mich. -- They're planning a hot time in Hell on Tuesday.<br><br>The day bears the date 6/6/06 -- abbreviated as 666, it is the "number of the beast" according to the Bible's Book of Revelation, often linked to the devil or the Antichrist.<br><br>And there's not a snowball's chance in Hell the day will go unnoticed in the unincorporated hamlet 60 miles west of Detroit.<br><br>Nobody seems more fired up than John Colone, the town's self-styled mayor and owner of a souvenir shop.<br><br>''I've got '666' T-shirts and mugs.

[...]<br> <br>Sildenafil was associated with significantly improved arousal, orgasm,and enjoyment compared with baseline (p &lt; 0.001 for each).Comparedwith placebo, the experience of arousal (p &lt; 0.01) and orgasm (p&lt; 0.05) were better during active treatment.

shouldnot make medical decisions based upon small studies that are identifiedas pilot studies. &nbsp;Doing so, one is likely to expose patientsto risks that have not been justified by sufficient research. <br><br>Second, it is important to examine critically the outcome measures usedin the study. &nbsp;Specifically, it is necessary to look beyondthe measures of statistical significance. &nbsp;The statistics inthis study look reasonably impressive, at first glance.&nbsp;However, those numbers do not tell you what you really wantto know. &nbsp;Remember, <i>statistical</i>significance

type='text'>Accelerated Knoppix</title><content type='html'>I know I've written about this before, so if you've read one of myprior posts on the topic, or if you already are familiar with theconcept of a live CD, just skip to <a href="#The_bottom_line">thebottom line</a> for the info that is specific to AcceleratedKnoppix. &nbsp;<br><blockquote>&nbsp;&nbsp;&nbsp; We affirm that theworld's magnificence<br>&nbsp;&nbsp;&nbsp; has been enriched by a new beauty:<br>&nbsp;&nbsp;&nbsp; the beauty of speed.<br> <br>Filippo Tommaso Marinetti - Manifesto of Futurism -<br></blockquote>That quote is on the <a href="http://www.alpha.co.jp/biz/rdg/ac-knoppix/index_en.html">homepage</a>for the Accelerated <a rel="tag" href="http://distrowatch.com/table.php?distribution=knoppix">Knoppix</a>project. &nbsp;What that means is that computer userscan boot from the CD and get a complete operating system and a complexset of applications, ready to use. &nbsp; It boots if the harddrive has crashed. &nbsp;It even boots if there is no hard drivein the computer at all. &nbsp;<br><br>There are several uses for a <a title="Wikipedia link" href="http://en.wikipedia.org/wiki/Live_CD">live CD</a>.&nbsp;Probably the mostobvious is that it enables a user to try an operating system or anapplication without having to install the application on the harddrive. &nbsp;So if you've never used <a title="Wikipedia link" href="http://en.wikipedia.org/wiki/Linux">Linux</a>before, and want to giveit a try, you can use alive CD to try it out, with minimal effort, andwith no risk of messing anything up. &nbsp;Or, if you've heardabout OpenOffice -- the free alternative to Microsoft Office -- andwant to see if itreally will

Wasserman, PhD, from Dermatologyand Cosmetic Surgery Associates in Greenbelt, Maryland, and Chevy ChaseCosmetic Center in Maryland. "There is a body of evidence that suggeststhat the facial expression of emotion may play a causal role in thesubjective experience of emotion. We initiated a small open pilot trialto determine whether inhibiting the expression of facial frowningcommonly associated with depression could help ameliorate depressivesymptoms."<br></blockquote>This was an extremely small study, involving only ten patients,without, and with double- or single-blind condition. &nbsp;Thatmeans that it is not possible to draw any valid conclusions, other thatto say that a larger, double-blind, placebo-controlled study might beworthwhile. &nbsp;<br><br>The idea is not without precedent. &nbsp;It is known that peoplewith anxiety tend to be overly vigilant concerning somatic symptomsthat are correlated with anxiety. &nbsp;When they notice suchsymptoms, it tends to increase their anxiety, which increases thesymptoms: a classic positive feedback loop. &nbsp;Sometimes,patients with anxiety disorders can learn to interrupt the feedbackloop, resulting in clinical improvement. &nbsp;As far as I know,nobody has tried anything like that with mood disorders, until now.<br><blockquote>A total of 10 patients who met Diagnostic andStatistical Manual of Mental Disorders, Fourth Edition, criteria forongoing major depression refractory to pharmacologic orpsychotherapeutic treatment were evaluated with the Beck DepressionInventory II (BDI-II) before receiving botulinum toxin A to theirglabellar frown lines.<br> <br>Two months later, all patients were reevaluated clinically and with theBDI-II.

&nbsp;<br><br>Perhaps the serotonin boost is not at all related to the clinicaleffect. &nbsp;It could be an&nbsp;<a title="Wikipedia link" href="http://" rel="tag">epiphenomenon</a>.&nbsp;Physicians generally know about epiphenomena, and arecautious about overinterpreting them. &nbsp;Pointing out the fact,that there is not necessarily a causal connection, is tiresome.&nbsp;Thus, when a skeptic takes pains to point it out, it merelyshows that the skeptic is not aware of how obvious it is tomedically-educated people.<br><br>As an aside, it occurs to me that epiphenomena are roughly analogous to<a title="Wikipedia link" href="http://en.wikipedia.org/wiki/Spandrel">spandrels</a>.&nbsp;If I felt like getting tediously philosophical, I could writea post outlining that analogy. &nbsp;Another time, perhaps.&nbsp;(A hint: just as a feature that evolves as a spandrel canturn out to be useful, sometimes side effects of mediation can beuseful.)<br><br>Sometimes it is difficult to avoid getting tediously philosophical.&nbsp;Oh well. &nbsp;It occurs to me also that this is anexample of how a good understanding of evolutionary theory can behelpful in understanding medicine, as Orac is <a href="http://scienceblogs.com/insolence/2006/03/medicine_and_evolution_part_i.php">fondof pointing out</a>. &nbsp;(As is my former residencydirector, <a href="http://www.sciencemag.org/cgi/content/summary/311/5764/1071?maxtoshow=&amp;HITS=10&amp;hits=10&amp;RESULTFORMAT=&amp;fulltext=medicine+needs+evolution&amp;searchid=1&amp;FIRSTINDEX=0&amp;resourcetype=HWCIT">RandyNesse</a>.) &nbsp;This is true regardless of whether youbelieve that evolution is responsible for the origin of species.<br><br>Putting that aside aside, and getting back to the point: Because it istiresome to hear skeptics harp on that string (the lack of afully-delineated connection between serotonin and depression) I wassurprised to see this article in a well-regarded journal:<br><a href="http://medicine.plosjournals.org/perlserv?request=get-document&amp;doi=10.1371/journal.pmed.0020392"><i>Serotoninand Depression: A Disconnect between the Advertisements and theScientific Literature</i></a>, by Jeffrey R.

Pharmaceuticalcompanies that disseminate advertising incompatible with theserequirements can receive warning letters and can be sanctioned. TheIrish equivalent of the FDA, the Irish Medical Board, recently bannedGlaxoSmithKline from claiming that paroxetine corrects a chemicalimbalance even in their patient information leaflets [29]. Should theFDA take similar action against consumer advertisements of SSRIs?<br></blockquote>Curiously, the authors devote several paragraphs to debunking theserotonin hypothesis, even though, in my opinion, their purpose couldhave been served with one or two citations. &nbsp;What is even morecurious is that they do not go on to draw a specific conclusion thatanswers the question they pose: they never answer directly the questionabout whether the FDA should take action against the pharmaceuticalcompanies that refer to the serotonin hypothesis in theiradvertisements. &nbsp;<br><br>In fact, they do make a good case against the pharmaceutical companies,and I happen to agree. &nbsp;It appears to be true, based upontheir argument, that pharmaceutical companies are not following FDAregulations regarding DTC advertisements. &nbsp;Moreover, theauthors make several other good points, such as this one:<br><blockquote>Patients who are convinced they are suffering from aneurotransmitterdefect are likely to request a prescription for antidepressants, andmay be skeptical of physicians who suggest other interventions, such ascognitive-behavioral therapy [<a href="http://medicine.plosjournals.org/perlserv?request=get-document&amp;doi=10.1371/journal.pmed.0020392#JOURNAL-PMED-0020392-B48">48</a>],evidence-based or not.<br></blockquote>I personally have spent a lot of time in the office, with patients,trying to undo the misinformation contained in DTCA. &nbsp;Itbothers me that I have to do that. &nbsp;I would much rather spendthe time providing good education, not undoing bad education.&nbsp;I would prefer to not have to deal with direct-to-consumeradvertising at all; but if we have to have it, companies really oughtto be held to the standards that exist to ensure balance and accuracy.</div></content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114816542652747583'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114816542652747583'/><link rel='alternate' type='text/html' href='http://corpus-callosum.blogspot.com/2006/05/serotonin-and-depression-disconnect.html' title='Serotonin and Depression: A Disconnect'/><author><name>: Joseph j7uy5</name><uri>http://www.blogger.com/profile/12806669663107445151</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='//blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVJBzauYzPUXYT0CJ_mAitRBt8G2SDKkcSagvAIpSw_EcqJl25b8N1K8POIiJiWSnjyddZqzRGp4FbixU8DgRDf7TP7ZJuGSsKRZIM0DQbfGclkbqiZ1kNiJKeUs1ylA/s220/j7uy5.jpg'/></author></entry><entry><id>tag:blogger.com,1999:blog-6281085.post-114810689413182953</id><published>2006-05-20T02:32:00.000-04:00</published><updated>2006-05-20T02:34:54.176-04:00</updated><title type='text'>Impeachment Update</title><content type='html'><div id="Politics">Howard Kurtz, <a href="http://www.washingtonpost.com/wp-dyn/content/linkset/2005/04/11/LI2005041100587.html">writing</a>on the <i>Washington Post</i> column, <i>Media Notes</i>,has an update on the brewing impeachment issue. &nbsp;It turns outthat some Republican strategists have been hyping the threat ofimpeachment. &nbsp;Apparently, they believe that the possibility ofimpeachment of the President might motivate some voters to go to thepolls and vote for Republican congressional candidates.<br><br>Personally, I do not see the problem with impeachment hearings, evenlooking at it from the Republican perspective. &nbsp;After all,with regard to the domestic spying operations, the Administration keepstelling us that if we haven't done anything wrong, we have nothing tofear. &nbsp;Certainly, the same principle applies to theAdministration itself.</div></content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114810689413182953'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114810689413182953'/><link rel='alternate' type='text/html' href='http://corpus-callosum.blogspot.com/2006/05/impeachment-update.html' title='Impeachment Update'/><author><name>: Joseph j7uy5</name><uri>http://www.blogger.com/profile/12806669663107445151</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='//blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVJBzauYzPUXYT0CJ_mAitRBt8G2SDKkcSagvAIpSw_EcqJl25b8N1K8POIiJiWSnjyddZqzRGp4FbixU8DgRDf7TP7ZJuGSsKRZIM0DQbfGclkbqiZ1kNiJKeUs1ylA/s220/j7uy5.jpg'/></author></entry></feed>If you would like to create a banner that links to this page (i.e. this validation result), do the following:
