Is It Time To Quarantine Air Travelers?



My wife and I just got back from Alaska on August 10, 2015 and within a few days became progressively symptomatic with an influenza-like illness that appears to be peaking today on day 5.  I know exactly how we were infected.  There were several ill passengers, particularly in close proximity who had not mastered coughing into the crook of the arm and who were actually coughing and sneezing over the top of the arm.  The plane was packed as usual.  We had paid an extra $100 to be able to sit in "economy comfort class".  In fairness there was about an extra 4 inches between my knees and the back of the seat in front of me (and I m 5'10'' on a good day).  Even that could not make up for the severe ergonomic problems of airplane seating.  I would quickly describe those as a lack of upright, even in the upright position.  Upright is at least 15-20 degrees from upright and over the course of a 5 hour flight that can create quite a bit of pain in anyone with a back problem.  This problem has been studied to some extent as evidenced by bullet point 3 on this web page.  The economy comfort class also comes with free alcoholic beverages, and I saw one passenger who was clearly uncomfortable rapidly down 4 drinks.  The other ergonomic problem is an ill defined seat.  It felt like sitting on 5 or 6 tennis balls all the way.

But back to the focus on viruses.  From discussing the problem with friends and family it is almost a universal experience that people get viral illnesses on their flight back from a recreational or work destination.

When I boarded a cruise ship recently I was screened for GI symptoms and asked if I had any recent illnesses as part of the check-in procedure.  That did not happen at any point when I got on either of the direct flight to or from Minneapolis.  In addition to the screening procedures there was hand sanitizer being actively and passively dispensed throughout the ship and on the ships TV channel the following message played continuously on a 24/7 basis:

Please wash your hands often and use the sanitizer stations provided throughout the ship especially when you are coming from ashore.  Always use a fresh cup when using beverage dispensers and refrain from using personal containers directly or on common beverage stations.  To stay healthy wash your hands with soap and warm water frequently.

 In comparing respiratory infections from air travel to Norovirus infections on cruise ships there are important differences.  The Norovirus infections occur in a well defined captive population in  very specific time period.  If an outbreak occurs it can become widely known, to the public relations detriment of that cruise line.  If a respiratory virus is contracted on a flight, everyone leaves the plane after arrival in a few hours and the total number of people infected is unknown.  There have been studies that look at the attack rates of people who have been on a flight where there is an index case of influenza and also the effects of using masks prophylactically when there are known index cases onboard.  There are no cautions to the passengers about how to prevent the spread of respiratory infections and (to my knowledge) no easy way for them to cancel in the event that they develop an acute upper respiratory in infection.  The CDC has some limited guidance on air travel, including some information on influenza transmission cabin air conditioning including the fact that it is partially recirculated and HEPA filtered 15-20 times per hour.  The most interesting study in microbial diversity in commercial aircraft that I could find was by Osman, et al (1) who compared conventional culture techniques to available molecular probes in 2008 in samples from 16 domestic and international flights.  They conclude that the molecular probe techniques demonstrated a much greater microbial diversity than culture techniques and that microbes varied significantly from domestic to international flights.  The molecular probe techniques identified 12 classes and 100 species of bacteria in cabin air, but in sufficiently low concentrations to not present a health hazard.  I am aware of studies in the past that have done viral cultures for respiratory viruses on filters in buildings but could not find similar data for commercial aircraft.  There have already been simulations about what happens when a person sneezes on an commercial aircraft, and those results are eye-opening.  I posted that in a look at the issue of hand washing and respiratory viruses.

Rather than go into excessive detail about the limited research that has been done so far, let me summarize a few facts and my conclusions.  Respiratory viruses can be transmitted during commercial air travel.  The attack rate for influenza virus has been estimated to be 2 - 4%.  There has been at least one study that shows masks can prevent infection.  There have been several simulations of how air travel potentially increases the world wide spread of airborne viral infections and some of these infections like corona virus and SARS outbreaks puts a significant burden on the international public health community.  Furthermore, the public health burden in terms of both morbidity and mortality is huge.  Influenza virus alone kills about 20,000 people annually in the United States or the equivalent of 5 large cruise ships in terms of total lives.  By comparison, there if far more press coverage of a Norovirus outbreak on a cruise ship and that virus is much less fatal.  Every American contracts about 2 - 3 respiratory viruses per year of varying severity.  That probably amounts to about 2-6 weeks of illness per year, associated with a disruption of work and daily activities as well as increased infection risk for those in the sphere of that person's routine.  There is also a risk for exacerbation of chronic illnesses like asthma and chronic obstructive pulmonary disease.

All of these considerations lead me to suggest (at the minimum) - the following measures:

1.  Intensification of study of airborne diseases especially respiratory viruses:  The technology is certainly there and there is no reason that molecular technologies cannot be applied to samples from commercial aircraft and I think that the HEPA filters are a logical place to start.  I would really like to see this become a focus of a private research fund, because it seems like the federal government has created numerous monitoring systems but no practical ways to detect high risk scenarios and disrupt disease transmission.  It seems like that is likely to occur only after an outbreak of a highly fatal respiratory virus occurs.

2.  Passenger education is critical:  The airline industry needs to adopt the methodologies that are currently employed in the cruise industry - educating everyone on the plane, screening for passengers at risk and quarantining them if necessary.  A critical piece of the education process is that while hand washing is necessary, it is not sufficient to prevent the spread of airborne respiratory viruses.  That public needs more awareness of that concept and what else can be done.  The method of quarantine is debatable and would probably need some flexibility based on passenger needs and acceptability and the severity of the problem.  It could include grounding until the infection clears, use of masks to block airborne infection, or possibly a section of the passenger cabin with more intensive HEPA filtering (altering air flow and humidity can affect the likelihood of virus transmission).

3.  Developing a culture to reduce the risk of respiratory virus infection:  Everywhere that I look we have practices in place that encourage the transmission of respiratory viruses.  Most Americans do not let respiratory viruses stop them from carrying on their business as usual.  In the past few days, I have personally walked through clouds of sneezed droplets because I happened to be following a fellow customer or coworker too closely at the wrong time.  I can't recall exactly when it happened, but getting rid of sick and vacation time and replacing it with paid time off or PTO days is an incentive for going to work sick.  Most of that sickness is respiratory viruses.

The American attitude to the common cold is far too casual.  It does not take into account the spectrum of symptom severity and the fact that many of these viruses can cause influenza-like illnesses and very severe syndromes.  Even a cold of moderate severity generally curtails a lot of activities and produces significant morbidity.  I don't understand how the medical and consumer community has come to this level of acceptance and denial of this collection of more-than-just-a-nuisance pathogens, but I would like to see it stop.

The American attitude toward the bad ergonomics of airline seating is another issue.  I think it is unfortunate that most passengers these days have never flown on a 747.  I may be overidealizing the flying of my youth, but planes today seem like dismal narrow aluminum tubes by comparison.

Regret




If you talk with people experiencing anxiety and depression for any length of time, one the the common recurring themes is regret.  Regret is one of those complex psychological dimensions that spills over into everyday life.  It is a significant disappointment somewhere on the trajectory of life associated with negative emotions.  It is such a common experience that friends and family members will sometime talk about their regrets, or the regrets of another friend or family member.  It is a universal human experience that can make you sad or anxious and also amplify those emotions when they are part of a more phasic mood disturbance.

In the above classic movie scene a young Marlon Brando playing Terry Malloy, a dock worker who is dealing with corruption and crime in that setting.  He had been a promising boxer until his brother Charley in this scene (played by Rod Steiger) convinced him to throw a fight in order to favor Charley's boss at the time.  Charley is also trying to dissuade Terry from testifying against that same boss in this scene.  Those are parts of a more complex plot, but it contains all of the detail that is relevant as Terry and his brother discuss the incident in this famous scene.  Terry seems to be expressing regret at two levels - one for throwing the fight and the effect it had on his reputation but more importantly for having an older brother who does not look out for his best interests and does not treat him well.  Charley seems to be treating him well in this scene only as a form of bribery.  He is offering him a paying job only to buy his silence.

People tend to regret a lot of things in the course of a lifetime - lost relationships, past behavior, missed opportunities, repetitive patterns of behavior that they don't seem to be able to break out of, and in some case entire periods of their life.  Common examples from the late teens to young adulthood include missed opportunities in relationships, school, and work.  It is very common to hear people complaining that they regret not applying themselves in school.  In some cases they regret choosing a particular career path and worry about whether it is too late to change.  There are myriad regrets possible just considering the family structure and the emotional reactions and expectations that people have of one another.  It can be combined with blame as in: "I wish you would have forced me to keep up those piano lessons."  At times people predict what might lead to regret in the future.  A common prediction is: "Your grandparents are not going to be around forever.  You might regret not going on this visit to see them."  In this era of social media, there are always posts about what you will regret on your death bed.  Apparently it won't be not spending enough time at work.  When I was a junior in high school, one of my friends predicted that I would regret not going to the prom.  In the decades since, I have had very few thoughts about high school and none on that dance.

One of the many questions that I find myself pondering in my down time is;  "What is the best conceptualization of regret?'  What is the best way to make sense of it?  What is the best way to adapt to it?  Does it make sense to think about getting over it?  At one point in my early 20s,  I took a harsh approach to some emotional thought patterns that could be troublesome.  My credo became "No guilt, no shame."  I started to spread the word.  I encouraged people to be proactive which is really the best approach.  If you make decisions on a daily basis that will not result in guilt or shame, what could be better?  No regret would be a welcomed by product.  Of course there were sacrifices along the way - spontaneity and risk taking being a couple of good examples.  You run the risk of being a "stick in the mud".  There is also the very real issue that you can just be wrong and despite your best intentions there are regrets along the way.

Regret is one of those concepts that seems to crossover from psychiatry to literature and English professors may do  better job of analyzing and appreciating it.  In Moby Dick, Melville introduces Captain Ahab's family in order to point out the contrast between an obsessive, all consuming pursuit of the white whale and time spent away from his family.  After casting a single tear of regret into the sea, a tear described as in the following passage:

"From beneath his slouched hat Ahab dropped a tear into the sea; nor did all the Pacific contain such wealth as that one wee drop."

Ahab launches into this soliloquy that is an ode to regret:  "Oh, Starbuck! it is a mild, mild wind, and a mild looking sky.  On such a day—very much such a sweetness as this—I struck my first whale—a boy-harpooneer of eighteen!  Forty—forty—forty years ago!—ago!  Forty years of continual whaling! forty years of privation, and peril, and storm-time! forty years on the pitiless sea! for forty years has Ahab forsaken the peaceful land, for forty years to make war on the horrors of the deep!  Aye and yes, Starbuck, out of those forty years I have not spent three ashore.  When I think of this life I have led; the desolation of solitude it has been; the masoned, walled-town of a Captain's exclusiveness, which admits but small entrance to any sympathy from the green country without—oh, weariness! heaviness!  Guinea-coast slavery of solitary command!—when I think of all this; only half-suspected, not so keenly known to me before—and how for forty years I have fed upon dry salted fare—fit emblem of the dry nourishment of my soil!—when the poorest landsman has had fresh fruit to his daily hand, and broken the world's fresh bread to my mouldy crusts—away, whole oceans away, from that young girl-wife I wedded past fifty, and sailed for Cape Horn the next day, leaving but one dent in my marriage pillow—wife? wife?—rather a widow with her husband alive! Aye, I widowed that poor girl when I married her, Starbuck; and then, the madness, the frenzy, the boiling blood and the smoking brow, with which, for a thousand lowerings old Ahab has furiously, foamingly chased his prey—more a demon than a man!—aye, aye! what a forty years' fool—fool—old fool, has old Ahab been!......." (Chapter 132).

His chief-mate Starbuck tries to talk him into ending the pursuit, but we all know how that turns out.  Even world class regret does not necessarily lead to self correction.  Similar statements cut across clinical and non-clinical settings.  I don't consider regret to be a symptom of any psychiatric disorder per se, but it will typically make things worse and in some cases be an unexpected point of focus.  What might be useful points for discussion?  A standard supportive approach would look at how human consciousness operates.  Whether you are a boy harpooner of 18 or a prize fighter in your early 20's, you are likely to make decisions at those times in your life that will not be the same decisions that you make 5 or 10 or 20 years later.  Eighteen year olds are energetic, eager to prove themselves, at their physical peak, and to a large degree see themselves as being invincible.  They are bound to make decisions much different than a 60 year who has battled life for 40 years and is left feeling spiritually withered.  Not being the same person at 60 as you were at 18, is not necessarily that intuitive in areas of life apart from the physical ones.  I think it illustrates that the situation remains dynamic and there is no reason to expect that different decisions can't occur.  In modern society, the decision to retire is a key decision that activates some of these thought patterns and associated regrets.

Physicians are professionals with some of the highest degree of regret.  There is the phenomenon of physician burnout fueled largely by the fact that they have limited control over what happens in clinical settings and that the people with more control don't know anything about medicine.  Many of the burnout surveys have to do with regret about going into medicine.  But there are also the inevitable mistakes in patient care.  I heard a neurosurgeon describe some of his regrets on public radio including a case where he tried to resect an additional amount of tumor that resulted in the patient being in a persistent vegetative state.  I was personally in a discussion of a transnasal resection of a growth hormone secreting pituitary adenoma that was wrapped around the internal carotid artery. The discussant was a neurosurgeon who had probably done more of this procedure by far than any other surgeon in the world.  That discussion went something like this: "This is the tumor and this is the artery (pointing to areas on an MRI coronal view of the pituitary gland and sphenoid sinus).  I am going to try to remove as much of the tumor as possible.  If I accidentally nick the carotid artery in this area, there is nothing that can be done about it.  That complication happens and I know good neurosurgeons  who have had that happen to them.  I can assure you I will remove only as much tumor as possible.  I will remove only as much as I would remove if you were one of my family members."  Since I heard that conversation, now 6 years ago, I have come to realize that it was more than just an informed consent discussion of the worst possible complications.  It was also a way that this surgeon had learned to set limits on himself and the drive to completely remove a tumor, even at a point where the risk may be  increasing exponentially.  I have seen good physicians who approached medicine as a science, who were not able to adapt to the inevitable mistakes or adverse outcomes.  Many ended up paralyzed with regret and needing to take time away from the field.  Some left for good.  I don't think we do a very good job with medical students and trainees in helping them develop a realistic view of the field.  A view that might temper them against the inevitable regrets.

As psychiatrists, we all need the vocabulary for discussing regret with our patients, because it is one of those things that crops up and takes over an appointment scheduled for another purpose.  We suddenly find ourselves in a supportive or psychodynamic or cognitive-behavioral or mindfulness mode dealing with the crisis.  Everything we had planned to do in that session, including assessing the patient's progress with their primary problem has gone out the window.  More importantly regret is part of life and not an error in thought or emotion.  Normalizing that experience will go a long way toward helping the person in crisis.

The New APA Practice Guideline




















I got a link to the new American Psychiatric Association (APA) Practice guideline today in my Facebook feed.  It was entitled Practice Guidelines for the Psychiatric Evaluation of Adults.  It is an updated version of a previous guideline by the same name.  I have pointed out on this blog that the APA seems to have all but abandoned the production of these guidelines with the exception of some extensive work for CMS to determine whether or not administrative guidelines about billing and coding were adequate.   When I complained to APA officials about the fact that they were not producing any new or updated guidelines I was told two things.  The first was to wait for this current guideline.  The second was that guideline production and updating did not seem to be a wise use of limited resources.  My interpretation of that remark was that it was defeatist and probably related to the fact that everyone is currently producing guidelines.  I guess that nobody at the APA recognizes the need to set limits on pro-business and pro-government guidelines that actively discriminate against psychiatrists and their patients.  Apart from a single APA President, that seems to have been the conventional wisdom that they have been using for the past 30 years.

I read the entire relevant section of the Guideline and that involves the first 52 of 170 pages.  The last section includes references, abstracts and methodology like bar graphs showing how many experts agreed that a certain type of assessment needed to be done in an initial assessment.  The introductory release explained that the guideline was based on an Institute of Medicine (IOM) publication entitled Clinical Practice Guidelines We Can Trust.   I have not been impressed with some of the work done by the IOM in the past and after reading three of their previous books wonder if it makes sense to read a fourth.  There are additional references on the methodology in the introductory sections of the document.  The release describes the guideline as modular so that each of the nine different modules can be updated regularly and separately.   That is a good idea that will hopefully add timeliness to the process.  One of the goals is to have the guideline widely disseminated.  Apparently anyone can download the document and read it.  There are the usual legal qualifiers pointing out the limitations of a broad document like this one and why it cannot be considered a standard of care.  I did not see the most obvious reason mentioned and that is that this concept is a legal one used for the determination of medical malpractice and that it really has no application in medicine.  Guidelines are referenced in Gutheil and Appelbaum's text:  "Third, another source of information about standards of care is the growing number of practice guidelines.........  It must be remembered, however, that even well-designed guidelines  do not necessarily address all possible approaches to a clinical issue." (1).  So the guideline disclaimer is clearly debatable in court.

As I read through the guidelines several things jumped out at me.

1.  It was not clear that this guideline was written for psychiatrists -  Some may say that this is implicit, but I am bothered by the fact that in the first 52 pages the word "clinician" pops up 34 times and the word "psychiatrist" pops up 17 times.  What would prevent any clinician from claiming that they have done everything listed in this document and therefore their evaluation is the equivalent of a psychiatrist's evaluation.  This is more than a guild or political issue as I will elaborate below.

2.  It was not clear what type of expertise was necessary to use the guideline - I suppose this is a minor variation of the first point, but technical expertise to me has always been a critical issue.  The guideline gets around this by saying it is not a "comprehensive" document.  I would not consider the recognition of acute medical and neurological problems or even chronic ones to be beyond the scope of a psychiatric evaluation.  I would not consider an abbreviated list of these conditions to necessarily render this a comprehensive document and it would certainly have more clinical value than a tedious list of all of the survey results.  The document also discusses tests in terms of the optimal ordering of tests and also specific kinds of tests.  What about who interprets those tests?  As a very basic example, I would go back to the days of the oral board exam in psychiatry and frequent questions about the use of lithium.  Board examiners were interested in what tests needed to be ordered to initiate and follow lithium maintenance therapy.  The goal of that exercise was to certify a safe practitioner of psychiatry.  In today's world, there is a much larger number of tests, interpretations and plans based on those tests.  This is a critical line of demarcation in some practice settings that seek to limit the medical role of psychiatrists.

It is apparent that the APA wants this guideline to be widely disseminated.  A related concern is that they may have not learned much from the wide dissemination of the DSMs over the years.  Although there is a partial financial incentive with DSM releases, the APA may be oblivious to the downside of everyone having a copy of this manual.  The pre-DSM-5 release rhetoric illustrates that a lot of critics had a very poor understanding of what the DSM-5 was and how it would be used.  Wide dissemination of a vaguely written practice guideline may have the same effect.  There is a common bias than anyone with a social brain who can speculate about the motivations and goals of others can do what psychiatrists do.  There are endless examples of various writers speculating about which public figure may have Asperger's or narcissistic personality disorder.  The sentiment in some circles seems to be: "If I have a copy of the DSM - I can diagnose people."  What is to prevent a similar co-opting of the Practice Guideline?

3.  There is nothing really surprising in the document - The assessment techniques are either obvious things that psychiatrists and psychiatric trainees do on a regular basis.   There are so many qualifiers that many approaches can be taken.  For example, the issue of coming back to an initial point to clarify the diagnosis if it could not be appropriately done in the initial interview was mentioned several times.  That is useful in cases when a patient is embarrassed or defensive about a particular aspect of their history.  In this regard, the document represents both content and process variables of the interview.  

4.  Tip of the cap to evidence based medicine - even when it is not needed - A common refrain throughout the guideline was:  The strength of research evidence supporting X is low, where X is the guideline of interest.  I summarized the guidelines and statements in the table below.  The numerical and letter designations can be translated as follows.  The numeral 1 is a recommendation.  The numeral 2 is a suggestion.  The letters A, B, and C are degrees of evidence reflecting high moderate or low degrees of evidence respectively.  The table basically reads as a recommendation or a suggestion backed by low degrees of evidence.




Using research evidence as a criteria for standard clinical methods is taking evidence based medicine to its absurd conclusion.   I am not talking about refinements in the way the history and physical has been done over the years, but the basic idea that a physician has to make a diagnosis and come up with a treatment plan.  Is there really any question that there are currently thousands of clinical trials that document positive treatment effects based on inclusion criteria that include a standard evaluation of the patient and the recognition of certain medical exclusion criteria?  The Guideline includes an explanation about why it is unethical to do certain double blind placebo controlled trials such as the study of suicide and aggression.  It does not comment on the important clinical question: "When does the anecdotal become statistical?"  To illustrate, if I am currently an inpatient psychiatrist and 100% of the patients I see are admitted for suicidal/aggressive ideation/behavior and my post discharge complication rate is very low (1 incident of suicidal or aggressive behavior every 500 discharges) - what is the likelihood that I am no more effective than placebo?  Do I really need a clinical trial to prove that I am doing something?  Are there any statisticians out there willing to speculate on that problem?    

5.  The information aspects of the evaluation - this critical aspect of the evaluation has not been studied in the field and the lack of these studies leads to a number of vagaries in the guideline.  It should be possible to illustrate the range of information exchange across a number of interviews and the optimal amount of information exchange in terms of diagnostic yield and enhancing the diagnostic and therapeutic aspects of the interview.   It is a way to advance the technical aspects of the field without deference to neuroscience.  Psychiatry has been stuck in essentially the same interview technology since the 1940s with no significant advances.  Looking at the information exchange that occurs in the interview is a long standing omission and it is probably the best way to advance this central part of clinical practice.

6.  A well deserved shot at the electronic health record  - After about two decades of hearing nothing but praise for the EHR and how it will revolutionize the practice of medicine and "save" us all hundreds of billions of dollars, its shortcomings are so obvious and so severe that even the APA gets it.  From page 44 of the Guideline:

"With the increasing use of electronic record systems, the structured but fragmented information that is common in electronic record notes can increase cognitive workload and reduce the quality of communication among those caring for the patient..."

That is a diplomatic way of saying that if you follow the suggestions for collateral information in the Guideline and are unfortunate enough to get either a printout or have direct access to an EHR, you might spend hours reading through hundreds of pages only to discover that the document has no discharge date, that it contains minimal information or that (in the case of lab testing) you can't determine the dates that any of the testing was done.  You will probably also encounter an EHR template approach to documentation that provides a series of "yes-no" responses where real information is traditionally used.  The current EHR is a plague on those specialists who require high quality information and plenty of it.  It should be apparent from the general requirements of this guideline that psychiatry is at the top of the list.

7.  Inconsistencies are present in many places - One of the better examples is several qualifier paragraphs that point out how descriptions may be necessarily vague and how to negotiate that in the assessment itself.  There are terms having to do with time as well as clinical descriptions.  The guideline says that it does not encourage stereotypical questions to complete the assessment, but at the same time suggests "quantitative measures" like standard checklists.  I cringe when I see that term because it was a term that was included in the Joint Commissions 2000 statement on pain assessment and treatment and we all know how that turned out.  To an old chemist, asking a person where they are on a ten point scale that rates pain or depression or anxiety is far from a quantitative measurement.  At some point, psychiatrists and physicians lost sight of the fact that certain organ systems (the brain in particular) by its very structure,  precludes quantitative analysis - and that is a good thing.  The authors of this guideline should at least attempt to explain how an obviously subjective and flexible evaluation can eventually lead to rigid "quality" measures that are also being used as if they are quantitative.  At some point, some professional organization needs to point out that most if not all of these measures are fabrications of the business community and government and they have little to do with medicine or science.  If the APA can say that about all of the points in their guideline, why can't they point out that the same "quantitative measures" are used in collaborative care and they mean the same thing.

8.  The serious dimension of the diagnosis - There are a lot of reasons why patients and families tend not to take a psychiatric diagnosis as serious as they should.  It took me a number of years in clinical practice before I realized that any informed consent discussion I have with a person should include whether or not that diagnosis is life threatening to them.  In some cases like talking with a survivor of a near lethal suicide attempt it is obvious.  In other cases like a major psychiatric disorder and a number of close calls due to a substance use disorder, it is less obvious.  I will tell a person that the condition they have is life-threatening and the treatment plan and their part in the overall treatment needs to take that into account.  There may be an associated discussion of voluntary and involuntary treatment as well as a clarification of my position in the patient's treatment and the associated rationale.  I think it is critical that this assessment is made and carefully documented for continuity of care purposes.

These are a few of my initial comments.  The new treatment guidelines is far from perfect but it is a start to get the APA back on track again to establish reasonable guidelines written by psychiatrists about the practice of psychiatry.  The introductory material suggests that the method will be to modify the various sections, but what is needed is another section or probably a new guideline on treatment planning and how that interfaces with the Evaluation Guideline.

A North American Cruise



Not going on a cruise was a always a high priority on my bucket list.  I am reporting that (for many reasons) I have failed in that pursuit.  My wife and I just got back from an 10 day excursion into Alaska by sea and out by land.  The first leg was a 6 day cruise from Vancouver, British Columbia to Juneau, Alaska and overland from there to Denali (Mt. McKinley) and back to Anchorage with a direct flight back to Minneapolis.  I started typing this as we left Ketchikan, Alaska headed for Icy Straight Point, Alaska. There is a mountain range silhouetted by the sunset outside my window.  The shore line seems to pass by at a rate much faster than the reported 16 knots, but that is not bad for a vessel weighing 93,000 tons.

Cruise ships these days are engineering marvels.  The one that I was on was 11 stories high.  It had a walking/running track on the top deck (200 meters/lap) with extensive spa and gym facilities.  The technical details of this ship are hard to find, but a little research showed that it was powered by 2 x 19 MW azimuth thrusters rather than propellers.  That explained the easy maneuverability of this nearly 1,000 ft long ship.  In front of the Hubbard Glacier, the captain was able to spin the boat in a circle for a couple of revolutions.  Sitting on the aft deck, the propulsion units have enough thrust to create prop wash that extends to the horizon.  A tour of these capabilities and the engineering involved would have been fascinating (for a few of us) but I understand the security constraints.

In the 5 months leading up to September each year about a million cruise ship passengers make this journey. As a psychiatrist who likes to keep track of cultural phenomena, this was one that I had missed.  The ship lines involved have created ports along the way with excursions to highlight the area resources and make the natural attractions readily available to a number of interests. A few examples include excursions into the world’s largest temperate rain forest capped off by a meal of fresh Alaskan crab. On that excursion today I learned some interesting facts. Ketchikan and the surrounding area on the island have a total population of about 10,000 people during tourist season, but when that is over the whole lower town built around the cruise industry shuts down and many people leave until next year. It rains almost 7 days a week in Ketchikan and the total annual rainfall is about 13 feet. One of the natives told me that people need to take Vitamin D and volunteered the typical dosing ranges of 2,000-5,000 IU per day. Some of the outliers were taking 10,000 IU. She said nothing about levels being drawn or cases of toxicity. The weather for this cruise was outstanding - generally sunny with temps in the 70s except for the period next to the glacier.   The town itself seemed to be organized like many small American towns.  The government buildings and fire department were most prominent.  I wondered what it might be like to be a psychiatrist in Ketchikan.  But I did not have too long to think about it, because in 4 hours we were back on the boat headed for Icy Straight Point.

In the meantime, I am nearly at the 50 day point of walking about 12,000 steps per day.  I decided to head up to the running track on the 11th floor of the ship and cover some ground.  This is the third day I am doing it.  There are a lot of people huddled in deck chairs in the bright sunlight. Even though the air temp is in the high 50s to low 60s, there is a stiff breeze blowing directly over the bow.  The only reasonable wear is heavy fleece or a windbreaker and a sweater.  I decided to sample my fellow passengers as I walked using an old survey method from wildlife biology.  From a demographic standpoint about 25% of the population was less than 40 years of age and half of that sample was less than 18.  At one point the cruise line had a special activity for the younger adults. Despite the age structure of the crowd, in the warmer climate pulling out of Vancouver, there was a steady loud beat of dance music on this deck, all compiled by a young disk jockey.  With this mix of ages there are always a number of clashes between the generations.  The energetic 10-15 year olds running randomly around the deck among the older folks.  A few grumbling old folks commenting negatively on the number of tattoos, especially on younger women.  Tall, thin, spectacled and silent post-adolescent girls are walking around in Converse high top basketball shoes.  Boys in that same age group are swaggering, swearing, and discussing Ivy League fashion.  The majority of the crowd was older and very well mannered.  There were a couple of groups celebrating anniversaries and weddings.  I had learned from another physician from a similar cruise that there were several people who required dialysis and there was a nephrologist on board to monitor that treatment.  The place was crawling with extraverts.  At times it was difficult to avoid conversations.  I saw a fellow introvert bundled up on a deck chair, facing away from the crowd and reading a book in the bright sunlight.  I could feel his pain.

Like most inescapable public gatherings the cruise creates quite a bit of tension within me.  At one point in my life I was a very active outdoorsman.  I was a tree hugger of the highest degree.  I was a white water kayaker and canoeist.  I nearly drowned three times in one day on the Montreal River in Upper Michigan and went back for more white water kayaking after that.  But at some point, all of that changed.  The landscapes seemed to be the same.  Hawaii was like Wisconsin with volcanoes. Colorado was like Wisconsin with mountains.  The terrain always looked better on television.  Alaska present thousands of miles of coastal mountains, some of which have the highest number of peaks greater than 10,000 feet of any mountain range in North America.  The glaciers were also unique, especially glaciers coming right out to the edge of the ocean, breaking off and creating waves, ice floes, and icebergs.  The ship navigated right into this area among the chunks of ice and spun around a few times before heading to Seward.
Polychrome Pass - Denali National Park

In everyday life I am still out there and very active, but the conditions have to be right and I have to be able to measure everything – miles, heart rate, cadence, speed, and all of the derivatives.  I avoid the hours from 10 AM to 3 PM or whenever my shadow on the ground is shorter than my actual height – a standard Dermatology tip on avoiding skin cancer.  I am no longer cycling in the rain.  The goals were more complicated.  I can no longer go out in the woods and plant trees with a grub hoe ignoring the biting flies and mosquitoes.  The parallel dimension was the demands of inpatient psychiatry.  There were decades of complicated problems, no solutions and confronting aggression and hostility at all levels on an almost daily basis.  I lived to go home, shut the door and enjoy the solitude.  Being stuck on a cruise ship where nearly everyone is an extrovert and trying to engage me in conversation is the antithesis of the last 25 years of my existence.  I am quite happy to be ignored but on a cruise ship it is common to encounter at least 10 crew members all of whom meet you very cheerily and begin with some variation: “Good morning sir. How are you today? Can I help you with anything?” I am sure that is standard cruise training is designed and implemented by extroverts.  Extroverts seem to dominate the customer relations fields and that’s why there is all of this unnecessary talk.  If I was consulting I might suggest an I (Introvert) Badge that translates to “You don’t have to ask me – if I have a problem I will ask you.” Or in the case of extreme Introverts “You don’t have to greet me – we are cool and I don’t think I am better than you.”

The entire cruise atmosphere was a study in contrasts for me.  On the one hand we were cruising through some of the most desolate places on the planet, ideal turf for introverts wanting solitude.  On the other we brought a party with us and even a party director who seemed bent on providing the maximum number of activities and entertainment per day.  That led me to think about people who might be stressed by the cruise.  Did anyone have anxiety or panic attacks?  I never made it down to talk with the ship's doctor about those problems, but it was easy to see how they might occur.  I also had the thought about people getting on the boat who were already depressed.  Would it lead to any adverse outcomes.  According to Wikipedia, there was at least one reported incident of a person who had gone missing on a cruise and who was seen jumping overboard when the security camera footage was reviewed.  I could find only one article on this phenomenon in Medline.  There is an associated literature that suggests that the mental health of seafarers in general, but primarily on merchant ships, may be poor as evidenced by suicides as a percentage of total deaths or deaths due to illness.  That author also suggests the numbers may be significantly higher if disappearances at sea are counted.  Suicide was also a topic during the tour.  Our tour guide said that Alaska had the highest suicide rate among the 50 states.  According to the CDC that is not strictly true but they do have the second highest rate at 23/100,000 or roughly double the age-adjusted suicide rate for the entire country.  They also have ready access to firearms.  Any Alaskan can carry a firearm concealed or unconcealed without a special permit.  One of our guides took a temporary break from the work to do a stint transporting mentally ill Alaskans to hospitals for treatment.  At this point, I can look back and see the opportunity to do a lot of good in Alaska if you are a psychiatrist who likes winter weather and are motivated to the point where you don't need a lot of collegial support.  But it is definitely a job for a younger person than I am.

Food is always a big point of discussion on cruises.  I can understand the advantages of not having to purchase or prepare it.  But the usual commentary is on how abundant it is and how good it is.  I am a very finicky eater and give it mixed reviews.  It was clearly abundant with large cafeteria style dining available all day long.  There were typically many entrees available followed by many deserts and pastries.  There was an ice cream bar and other specialty (pasta, eggs Benedict, pizza) stations on the side.  Food consumption there was unlimited and there were no additional charges.  You just walk into the cafeteria as many times a day as you like and you don’t have to pay anything for food.  In addition, there were two formal dining areas that needed reservations with more limited but high end entrees and appetizers.  Food consumption in those venues was limited to the standard restaurant style meal at no additional charge.  Finally there were four more restaurants that required additional payment for additional high end cuisine with consumption limited to that meal.  Beverage packages required the use of a pass card and prepayment of various beverage packages.  It should come as no surprise that cruises are risky for people trying to control their weight.  Before getting on this cruise a coworker told me that when her mother came back from a cruise she was almost “unrecognizable” due to weight gain.  Unless there is a conscious plan to limit consumption and exercise weight gain must be the rule on most cruises.

As far as the quality of the food, I give mixed reviews.  I am not much of a carnivore, but I do consider myself to be an expert in breakfast type foods, pizza, pasta, chicken, fish, and desserts.  If I compare the meals from the specialty sit down restaurants with restaurants within a 10 mile radius of my home it is clearly inferior.  That is not to say it was not good, just not excellent.  Almost everybody on a cruise raves about the food.  Their opinions may be biased by the overall cost of the cruise, the emphasis on food onboard (galley tours, discussions with the chef, wine tastings, etc), availability to well past the satiation point, and the ease of availability by no acquisition or preparation time by the onboard guest.  In addition, one of the few consistent television programs available onboard was Top Chef and it was on 24/7.  It has been trendy in the press to slam Americans for gluttony and obesity, but I won’t go there.  About 90% of the guests were Americans and Europeans from various ethnic origins, followed by Asians from various countries and then guests from Spanish speaking countries.   The cuisine was a mixture of American, Thai, Indian, and Japanese foods and it got good reviews from people originating from those countries.   I don’t think anyone was in an eating frenzy, just consistent consumption.  The majority of the food selections were very healthy and the main problem for consumers was portion control and limiting carbohydrates.

Alcohol consumption also seemed well controlled.  There were hierarchies in the beverage packages, most cost for the high end package containing alcoholic beverages.  There was a shopping area that sold expensive alcoholic beverages in large bottles with a duty free advantage, but I never saw anyone in that shop. Most of the drinking occurred in the deck and spa areas and with meals.  There was a meeting listed for anyone who was a friend to Bill W.  That may not be the rule on all cruises.  I listen to a morning talk show on the way to work and heard that the people on that show were aware of some "rock and roll" cruises that needed to make extra stops to pick up more alcoholic beverages.  This was a cruise that seemed to target families and multiple generations.

There is a curious tradition of formal dining that persists to this day.  I have been told that early cruises had assigned seating in the dining areas and at times that involved eating with the captain.  In those days everyone had to be dressed formally for it – for men that meant a sport coat and tie.  That tradition persists today but only on 2 days of the cruise.  It seems an unnecessary artifact to me.  The captain doesn’t eat with the guests.  I was told by one of the crew that they believe it encourages more socially appropriate behavior and a classier atmosphere.  My guess it that it probably has no more impact than the “no shirt, no shoes, no service” rules posted in various part of their literature. The extra attire takes up valuable room in the suitcase of nothing is really added.  My guess would be that all of this window dressing is the work of Extroverts (“Isn’t dressing up in formal attire fun?”).

After looking at a number of other comparisons like entertainment, electronic devices and Internet access, total cost of the cruise and associated excursions – I realized that an obsessive approach could be taken in the analysis. There are several web sites that take this approach.  The overriding question for me was what are the real differences between people who like cruises and people who don’t.  Whenever I give my opinion there is a general outcry that I am unreasonable and that my wife is a saint for putting up with me.  How could I not like a cruise?  And like most things it is a question of preferences.  My preference for eating carbohydrates dates back to an early age and I know the correlates and I think I know how all of that works at some level.  I also realize that those same mechanisms can produce preferences in billions of my fellow humans that are not my preferences and in this case it means that (at least on the surface) many more people seem to prefer cruises more than I do.

Supplementary 1:  This post was originally completed aboard a cruise ship sailing for Glacier Bay, Alaska - just off the coast from Gustavus, Alaska about 48 miles west of Juneau.



That is me holding up the sign to Yukon (formerly known as the Yukon Territories) just north of Juneau and 600 miles south of the city of Dawson (formerly known as Dawson City).  My ancestors were given the name Dawson on Ellis Island, because their name was not pronounceable, so the founder of Dawson City is not a relative.

Supplementary 2:  Sometime after posting this, I discovered that the late David Foster Wallace had been interviewed by Terry Gross on her public radio program Fresh Air.  In that interview he talks about an article he wrote on going on a cruise and discusses that about 1/4 of the way down in the transcript.  He also wrote a piece called Shipping Out: On the (nearly lethal) comforts of a luxury cruise.  All of that writing can be found by search engines.  David Foster Wallace is an acclaimed writer and his writing about cruises is both accurate and entertaining.  It has an added dimension (especially in the Fresh Air transcript) of considering whether fun and enjoyment can be managed.

Admission, Discharge and Readmission Policies - No Better Example Of Business Driven Pseudoscience


One of the recurrent themes of this blog is that the application of science to medicine, especially at the public policy level has plummeted over the past three decades.  That has been directly attributable to the influence of business on all levels of government.  One of the more pervasive themes is that the behavior of health professionals is best accomplished by incentivization.  In other words financially punish physicians to get them to change their behaviors that you don't want or financially reward the behaviors that you want them to produce.  I haven't looked at the scorecard lately, but my guess is that the punishments greatly outweigh the rewards.  Maybe my perspective has been skewed by working for an HMO for many years that considered it a reward if they "held back" part of your salary and then gave it to you if all of the physicians in your group met the desired productivity targets.  I am sure it took the MBAs a while to dream that one up.  The equation seems to be as simple as -  "OK here is what we want the goal to be.  We don't want to pay out any rewards anymore.  Let's just penalize people for not meeting the goal until eventually everyone is compliant with the goal."  There is probably no better example than the Medicare Hospital Readmissions Program.

A recent editorial in JAMA notes that the 2013 readmission rates for Medicare patients is about 18% within 30 days (1).  That is associated with a potential cost of $26 billion.  Since 2010 Congress has levied a 3% of Medicare reimbursement penalty on hospitals who have readmission rates that are considered too high.  The problem is that 80% of hospitals are being penalized are safety-net hospitals or those that have a disproportionate share of low income patients.  Those hospitals are more likely to be penalized all three years since the penalty started  and they are more likely to be the hospitals with the lowest operating margins.  The likelihood of penalty also correlates with the percentage of patients treated who are elderly and live with poverty or disability.  

The authors opine that hospitals should not be penalized "because of the demographic characteristics of their patients."  They point out that the evidence suggests that is exactly what is happening and they conclude:  “Targeting hospitals for penalties, even if indirectly, simply because those hospitals care for more poor people is not good policy”.  They use this as a foundation to build their argument for a proposed policy initiative – The Hospital Readmissions Program Accuracy and Accountability Act of 2014.  It builds in safeguards for hospitals treating patients from a disadvantaged socioeconomic status.   

The obvious problem with the authors’ logic here is that they seem to not realize that discrimination against patients of the lowest socioeconomic status has been institutionalized and occurring for decades.  The people I am referring to are those people with addictions and severe psychiatric problems.  The facts are clear.  For the past 30 years, even though psychiatric disabilities rank as some of the top 10 disabilities by any measure, they get a much smaller fraction of the health care dollar for care.  I have used the example of a middle-aged man or woman being hospitalized through the emergency department for acute chest pain.  I don’t know the fraction of those people who are discharged the next day.  But consider that basic scenario if the evaluation of chest pain turns out to be non-cardiogenic.  In the hospital where I have worked that generally means an evening on telemetry and serial troponins and either a stress echocardiogram the next day or an echocardiogram and a stress test.  Price tag about $25-30,000 for less than 48 hours in the hospital.  On the other hand,  let’s say a person has an exacerbation of an affective psychosis and is not able to function at home or has put themselves at risk.  The will be hospitalized in a very low tech psychiatric unit, the goal of which is to discharge them when they are no longer “dangerous” or to discharge them upon request if they cannot be held involuntarily.  Irrespective of the price tag for this care the best available data I have on the DRG reimbursement for this care is about $4,800 irrespective of length of stay.  The economic incentives all line up to rarely provide them with the discharge resources they require to maintain even a subsistence life style and remain stable enough to stay out of emergency departments or jails.  Furthermore in many cases, states previously charged patients a for a portion of their medication costs per month out of their disability income.  The direct and indirect costs incurred by patients and families with severe mental illness and addictions are a travesty of the highest magnitude.  The rationing mechanisms that have been in place for the past three decades have results in care that is subpar relative to any other medical specialty.  It has created an entire population to patients with chronic illnesses that are discriminated against.  The financing of care for them has set a number of perverse incentives that would seem to be more destabilizing such as an incentive for hospital discharge in order to beat the designated days in the diagnosis related group (DRG) and readmit them if necessary.  If the entire DRG incentivization for admissions and discharges is pseudoscientific sleight-of-hand based on very crude demographic variables - why would we expect readmissions policies to be any different?

The second dimension of this care is just how unscientific care based on demographic factors is in the first place.  I was previously in a practice where “consultants” who had never practiced medicine came in and commented on the “complexity” of our patients.  At the time I was caring for many patients who I knew would never be admitted to other general psychiatric units in any other hospital in the state due to their medical complexity.  The consultants concluded that my patients were no more complex than any other patients in the state even though they could not define the measures they used to make that determination.  Nobody mentioned the inherent conflict of interest when a pro-discharge administration hires consultants that agree with their world view - discharge patients as soon as possible.

In another scenario and on a committee, I asked if the demographic determined characteristics and time lines for treating community acquired pneumonia led to any differences in mortality or complications – and nobody knew.  The original Big Data approach in medicine looked at HEDIS variables.  Any practicing physician knows this is an incredibly crude approach that in many cases is meaningless.  There is no better example than saying that treating acute and chronic psychosis in a few days makes no difference in outcomes, when nobody knows the best treatment approach and practically no hospital screens for functional or cognitive capacity - two well known areas of psychiatric disability.  In the outpatient sphere, it is the equivalent of saying that 10 or 20 minutes three or four times a year with an emphasis on medications that are not likely being taken by the patient can possibly affect their real life outcome.

In the case of patients with addictions the treatment is more dire.  When a person using heroin, alcohol, and excessive amounts of benzodiazepines cannot get admitted for detoxification or they cannot get admitted for residential treatment, society and its representative governments at all levels are saying that this is a situation where we can ignore conditions that are clearly life-threatening and in many cases fatal.  We can ignore them because businesses and governments say that this is a collection of disabling and life-threatening diseases that we can ignore so that they can either make money or divert money to treat more socially acceptable life-threatening and disabling diseases.  

This is all a clear pattern of discrimination that not only affects the elderly but anyone with a psychiatric disability or addiction.  If the authors want to do something about that – I say let’s start by reversing over 30 years of discrimination against those with psychiatric and substance use problems that is clearly based on socioeconomics especially the lack of a vocal political constituency, very poor research based on demographic variables rather than complexity, and a lack of innovative research based on poor resource allocation.

Silence on Pro Publica's Recent Big Pharma Payment Disclosures















OK silence as far as psychiatry goes.

For the past ten years we have heard both individual psychiatrists and monolithic psychiatry maligned for accepting Big Pharma cash for presentations, expert consultations, or whatever.  The implications being twofold - that there were no legitimate reasons why a physician seeing patients should be in the employ of a pharmaceutical company and (courtesy of the Institute of Medicine) that since you can't really tell what is a real conflict of interest versus the appearance conflict of interest without some additional leg work that we should just consider any potential conflict of interest an actual conflict of interest.  At that point, the body in the US with the most real conflicts of interest that I can think of (Congress) decided that all payments from pharmaceutical companies and device makers should be catalogued in a data base for everyone to see.  When I accessed the database, it was a clear example of government information technology (IT) at its worst.  There are numerous examples of government IT projects being abandoned as unusable after an investment of hundreds of millions of dollars.  The recent hacks exposing the private information of millions of government employees and millions of classified documents are good examples of the lack of quality in government IT.  Why expect any higher bar with payment disclosures to physicians?

Rather than navigate the unnavigable, a better approach is to look at secondary data sources who have the time and staff required to translate the data like Pro Publica.  On their opening web page there is a small window half way down that asks:  "Has Your Health Professional Received Drug Company Money?"  I plugged in my name as a double check on the system and it returned 27 results with either a first or last name George or a last name Dawson.  None of them was me (which is accurate).  Only one of them was a psychiatrist and that physician had received a total of $88.  The remaining physicians had received anywhere from 0 to $18,450.  I would certainly not be very happy if I was included in this database for receiving zero dollars and wonder how often that mistake is made?

The bar graph of what types of fees were paid by the industry is instructive.  The largest single group of payments were for "Royalty or License" and number of current brand name chemotherapy and antiviral drugs were mentioned.  The next category was "Promotional Speaking".  I can't imagine that rheumatologists, endocrinologists, and cardiologists are not in demand to speak to primary care physicians about the latest developments in their fields.  I have spoken at Primary Care Updates in psychiatry for primary care physicians.  Are those presentations classified as "Promotional Speaking" if a pharmaceutical company sponsors it and the speaker does not mention one of their products by name?  I have similar questions about "Consulting Fee".  If a physician has a specific expertise and is paid by the private company for that expertise, in my opinion they are no different than any other University faculty in similar positions.  The idea that a physician's entire life is encompassed in relationship with patients and that this is somehow a sacred trust is a myth that is perpetrated by concerns who are quite willing to exploit all physicians on that basis.  They are all listed in various places on this blog.

One of their lead stories is A Pharma Payment A Day Keeps Docs’ Finances Okay.  In that article they focus on a neurologist who received $594,363 from 29 different pharmaceutical companies.  They looked at the top rated physician and concluded that she received payments from pharmaceutical companies on 286 days out of the year.  14,600 doctors received payments on at least 100 days per year.  A total of 606,000 doctors received payments, but then again there are people listed in my first search who apparently did not receive any money.  And then there was this excerpt:

"The nation's 3,900 rheumatologists in the data averaged 40 days of interactions with drug and device companies, more than doctors in any other large specialty. They were followed closely by endocrinologists, electrophysiologists and interventional cardiologists...."  In my home state of Minnesota they list the top 20 physicians receiving money from pharmaceutical and device companies and 19/20 are surgeons (orthopedic, spine, eye) and one is a cardiologist.

No psychiatrists?

That is a curious phenomenon considering how frequently psychiatrists are maligned for financial conflicts of interest in the popular media and blogosphere.  No Senate investigations of rheumatologists, endocrinologists, neurologists, or cardiologists?  No attacks on their professional organizations?  No suggestions that their diagnoses, interventions, prescriptions, publications or professional behavior are questionable based on their reimbursement from private industry?  Why is that exactly?  I certainly have plenty of good ideas.

In order to clarify the real picture here, I sent an e-mail to Charles Ornstein, the lead author of the  "A Pharma Payment A Day..." article.  I asked him to post the statistics by specialty including the percentages of physicians getting some payment, per capita payments or by whatever metric they chose.  Considering the scope of payments suggested by these tables, my speculation is that there will be several physicians in the tens of millions of dollars category and that none of them will be psychiatrists.   But I am content to wait to see if he posts those results.   

Until then, don't ever believe that what you read about psychiatrists is a random event free from the usual antipsychiatry biases.

No matter what happens with the Pro Publica data - don't believe that anyway.

Depression and the Genetics Of Large Combinations










from:  CONVERGE consortium.  Nature. 2015 Jul 15. doi: 10.1038/nature14659. [Epub ahead of print] - see complete reference 1 below.         



This is an interesting effort from a large number of researchers looking at candidate genes in major depression. The authors studied major depressive disorder (MDD) in 5,303 Han Chinese women selected for recurrent major depression compared with 5,337 Han Chinese women screened to rule out MDD. The depressed subjects were all recruited from provincial mental health centers and psychiatric departments of general hospitals in China. The controls were recruited from patients undergoing minor surgical procedures in general hospitals or from local community centers. All of the subjects were Han Chinese women between the ages of 30 and 60 with four Han Chinese grandparents. The MDD sample had two episodes of MDD by DSM-IV criteria. The diagnoses were established by computerized assessments conducted by postgrad medical students, junior psychiatrists, or senior nurses trained by the CONVERGE team. The interview was translated into Mandarin. Exclusion criteria included other serious medical of psychiatric morbidity (see details in ref 1). 

Whole genome sequences were acquired from the subjects and 32,781, 340 SNPs were identified, 6,242,619 were included in genome-wide association studies (GWAS). Figure 1 above is the quantile-quantile plot for the GWAS analysis resulting from "a linear mixed model with genetic relatedness matrix (GRM) as a random effect and principle components from eigen-decomposition of the GRM as fixed effect covariates." I won't pretend to know what that methodology is, even after reading the Methods, Supplementary Notes section. I expect that it would take a more detailed explanation and in the era of essentially unlimited online storage capacity, I would like to see somebody post it with examples. Without it, unless you are an expert in this type of analysis you are forced to accept it at face value. I am skeptical of manipulations of data points that provide a hoped for result and can cite any number of problems related to this approach. On the other hand information of this magnitude probably requires a specialized approach. 

In this case the authors found two loci on chromosome 10 that contributed to the risk of MDD. They replicated the findings in an independent sample. 



One of the features that I liked about this paper was the focus on patients with severe depression. I have lost count of the number of papers I have read where the depression rating scores were what I consider to be low to trivial. Many rating systems used in clinics seem to use these same systems for determining who gets an antidepressant and who does not.  Whenever I see that, I am always reminded of the "biological psychiatry versus psychotherapy" debates that existed when I was in training in the 1980s.  Once of my favorite authors at the time was Julien Mendlewicz and anything he would publish in the Journal of Clinical Endocrinology and Metabolism (4-6).  There is a table in one of his studies with the HAM-D scores of the patients with unipolar depression he was seeing that ranged from 30-57 with a mean of 41+/- 10.  For bipolar patients in the same study the range was 30-43 with a mean of 36 +/- 5.  One of those patients could not be rated initially because of severe psychomotor retardation.  These are levels of depression that are not typically seen in depression research from either the standpoint of basic science and probably never for psychopharmacological research.  Much of the research that I am aware of allows for the recruitment of patients with HAM-D scores in the high teens and low 20s.  I don't think that is the best way to run experiments on biologically based depressions or antidepressant medications, but there is rarely any commentary on it.  The CONSORT group in this paper finally comments on this factor as being a useful experimental approach even though Mendlewicz was using it in the 1980s.

The second issue that crops up in the paper is replication.  The authors validate their original work by running a second sample for validation.  That is the approach we would use in analytic chemistry.  If we were using a new technique we would run samples in triplicate or in extreme cases in sets of 5 to make sure we could replicate the analysis.  It reminded of one of the first great genetic marker papers in the field that was published in the New England Journal of Medicine by Elliot Gershon's lab in 1984 (2).  It was an exciting proposition to consider that fibroblasts could be grown from a skin biopsy and the muscarinic cholinergic receptor in those fibroblasts would be a marker for familial affective disorder.   The general observation in this pilot study of 18 patients was that they had an increased muscarinic receptor density in fibroblasts compared to controls and that the relatives with histories of minor depression had receptor densities that were more similar to the subjects with mood disorders than normal controls.  The subjects with familial affective disorder were defined as subjects with bipolar I, bipolar II, or major depression according to Research Diagnostic Criteria (RDC).  No rating of depression severity was made acutely or on a historical basis.  These findings could not be replicated, in the end even by the original lab.  That process played out in the pages of the New England Journal of Medicine (3) and the original findings were withdrawn.  It would be interesting to look at how often a similar debate occurs in a prestigious journal these days.  Estimates of non-replicable findings by the pharmaceutical industry suggests that it should happen a lot more often.   

In terms of the original paper, the sheer amount of information involved in the genetic code is staggering.  Just looking at the 130 millions base pairs on Chromosome 10 and thinking about combinations of 2, 3, 4, 5, or 6 base pairs yields the numbers in the table below entitled "Combinations of 130 million base pairs."  The exponential notation ranges from 1015 to 1045 or a quadrillion  to a quattuordecillion combinations.  Figuring out the best way to determine which combinations are relevant in illnesses with polygenic inheritance will be an interesting process.
