The Moral Dilemma Of Alcohol Exposure

Before anyone schools me about Prohibition - I give lectures on Prohibition. I know it doesn't work and I know the reasons why. I also know that talking about restricting intoxicants in any way is counter to the current zeitgeist of liberalizing their availability.

I also treat alcoholics and I know how that works. When I see Minnesota's largest and most famous retailer opening up large and attractive liquor stores where there used to be not so attractive foods courts and positioning it right across from the cash registers - I know that will be a problem for a lot of people trying to stay sober. I know that for many people in recovery - an attractive liquor store in their favorite retail store or grocery store creates a very high probability of relapse - even if they know that relapse may result in death or severe disability. In Minnesota liquor stores hours is another issue. In states where liquor sales are prohibited like Minnesota, it is incentive to drive across the border into bordering states in order to buy alcohol. A modification is the availability of low alcohol content beer from grocery stores and gas stations.

Another proxy measure for relapse risk would be the total number of bars in each state.  That data is harder to get.  I have information from a tavern owner that the business organization representing them sets the maximum number at 1 tavern or bar per 500 people, but the actual limits are subject to local jurisdiction.  In reality the maximum tavern/bar concentrations occur in North Dakota, Montana, Wisconsin, and South Dakota ranging from 1621 - 2268 people per tavern/bar.  At the lower end Virginia ranks 50th at 64,773 people per tavern/bar. (US Census Bureau Data per The Forum).

Are retailers that desperate that they all need to compete in this low margin business? Why are governments in this business at all? I know that there are vocal people everywhere who argue for their unalienable right to intoxicants. One of the main arguments has always been that the vast majority of people can drink and not incur any problems from it. What about the people who cannot? Binge drinking, alcohol poisoning, and excessive alcohol use are all major public health problems according to the CDC. The direct and indirect cost of excessive drinking in the US is about $249 billion in direct and indirect costs.

One of the main arguments of cannabis advocates is how dangerous alcohol is. Alcohol costs $1.90 per drink according to the CDC in complications from drinking. That cost is probably artificially low because treatment and detoxification from alcohol is rationed and most people don't get anywhere near the level of treatment they need. In Twin Cities metro hospitals - drug and alcohol use can account for up to 60% of admissions. Potential consumer advocates in this case belong to an organization that values anonymity and as far as I know has not been very politically active.

The CDC (Community Preventive Services Task Force) suggests that alcohol excise taxes need to be increased, alcohol outlet density needs to be decreased, hours of sales need to be decreased rather than increased, and retailers need to be held liable for damages caused by underage or intoxicated drinkers. The tax suggestion reminds me of the general theory of sin taxes and why they really don't work from a governing standpoint. It basically generates money for politicians to spend and is typically diverted away from any stated use that involves treating complications of the activity.

To me the alcohol issue is much bigger than who sells it, but governments have a big problem at the moral and public health levels. Just carrying forward the CDC recommendations invites rhetorical response about prohibition or temperance. I have found myself in illogical arguments with both individuals and families about the right to drink oneself to death. Make no mistake about it, the issue was not suicide - just continuing to drink with advanced liver disease and repeated hospitalizations for bleeding problems and encephalopathy due to advancing liver disease and the associated anatomical and physiological changes.

At its base, the alcohol problems and tolerating excessive alcohol use is a cultural problem. In the Midwest where binge drinking is most prominent, teenagers start drinking in middle school. In many areas it is a rite of passage. Even though the majority of people don't drink. It is very difficult to find social settings that are alcohol free. Alcohol use in most settings is promoted as the social norm with the exception of a few subcultures. Barring a widespread cultural movement that promotes moderation or abstinence, it appears that the usual educational measures about the dangers of alcohol use will be the primary intervention point. Secondary and tertiary prevention depends on a robust system of care for alcohol use and that currently does not exist. In some cases close monitoring by the correctional system for people with DWI infractions can be effective, but that does not address either the group of people who do not come to legal attention or those for which legal intervention is not a deterrent.  It also does not provide long term solutions to the problem of continued alcohol use.

Despite all of the current hype about how some intoxicants are wonder drugs and the ongoing arguments about legalization of all or most intoxicants - I can't help but see this as another moral dilemma. The will of the many basically writing off the serious problems of the few. This often plays out in families where one member clearly has a severe drinking problem and the others (usually a spouse) refuses to not drink in front of them or not have alcohol available in the home.  It all comes down to the rationalization that everyone can control their drinking or that drinking can be seen as bad behavior and that is obviously not true.

The moral dilemma of increasing alcohol availability or the government sanctioned availability of any intoxicant is the same.  It is based on the theory that people in general can use these intoxicants without damaging other members of society or themselves to the point that they do not become a cost to the rest of society.  That essentially writes off the group of people with uncontrolled use who cannot do that.  American society traditionally handles that problem by punishment and rationing availability of treatment and detox services.  Functional detox services staffed by physicians are practically unheard of.  Contrary to that guy in your freshman philosophy course who doubted the meaning of everything - moral philosophers can also add a perspective here.  Consider this quote from Blackburn about the nature of moral knowledge:

"There are countless small unpretentious things that we know with perfect certainty.  Happiness is preferable to misery, and dignity is better than humiliation.  It is bad that people suffer and worse if a culture turns a blind eye to their suffering.  Death is worse than life; the attempt to find a common point of view is better than a manipulative contempt for it." (1).

The availability and treatment of alcohol related problems in American society on one hand and the motivation to profit from it on the other hand seems to stand Blackburn's quote on its ear.  In the US there is a clear blind eye approach to alcoholism.

It may be time to come up with a better plan for living.

Basic Models

In order to bring some clarity into the discussion of why neuroscience is important for psychiatrists, I thought I would get back to the basics.  I have three models in the above graphic that I think represent the basic conceptualizations of the brain in my lifetime.  They are very basic models, but I think reasonable jumping off points for further discussion.  They also serve to make my point about the importance of neuroscience.  I realize that there is a natural human tendency to be argumentative.  When I mention neuroscience or even science it seems that many psychiatrists and interestingly their detractors both get irritated.  I can understand why the detractors are irritated since many of them are at the level of Black Box thinking in the above diagram.  I will elaborate further, but many of them seem to consider the brain an amalgam of various qualities that either defy understanding or are unnecessary to understand because the brain may be involved at the very periphery of human behavior if at all.  But I don't understand any attitude on the part of brain professionals like psychiatrists that doubt the importance of neuroscience. With that let me proceed with the three levels of thought about the brain in the above diagram.

The Black Box embodies what people have thought about the brain since the beginning of time.  The brain is a mystery on the one hand and immutable on the other.  The reality of that situation could not be denied for long.  It was obvious that people with clear brain damage who survived the initial insult could have a number of changes in cognition, personality, and social behavior.  The black box view eventually gave way to mind-body dualism that held there were a number of mental phenomenon that could not be explained  by physical properties alone.  That is really the last refuge of the Black Box and that is that the conscious human state has not been explained in terms of how it arises from the neural correlates of consciousness.  It is an active area of research in the Clear Box area today.  It is always interesting in terms of who adheres to Black Box thinking these days.  I can't think of any legitimate science that occurs using this model.  Pre-modern and modern neuroscience if anything has clearly dispelled black box and most mind-body duality.  Some philosophers and antipsychiatrists are at this level.

In the Grey Box Box things got clearer.  The transition from Black to Grey to Clear is not a well defined boundary.  The best example that I can think of is German neuropsychiatry at the beginning of the 20th century.  Much of that movement was focused in asylums.  There is a famous picture of giants in the field like Kraepelin. Alzheimer, Nissl, Binswanger and others who were active at the time.  These psychiatrists made good phenomenological observations but they were also focused on gross neuroanatomy.  In the case of some illnesses like Alzheimer disease some observations could be made at autopsy.  In the case of schizophrenia and bipolar disorder, gross anatomical changes were not evident.  Although that is a negative finding. it is a finding that propelled a century of more sophisticated neuroanatomy, neurophysiology and the beginnings of a much more sophisticated molecular  biological approach to functional mental illnesses or illnesses with no gross anatomical or physiological markers.

While neuroscience was moving forward at a slow pace, there was some slight progress on the fronts of diagnosis and treatment.  The DSM is always a controversial document, largely because there is never any shortage of self-proclaimed experts in psychiatry.  Psychiatrists know the limitations, what can be tested for, what physical illnesses are important to rule out, and what states can be cause by drug or alcohol intoxication, chronic use and withdrawal.  These medical and intoxicant induced states are all clear medical illnesses by any definition as well as the associated syndromes.  There is a disclaimer in the DSM about who should be using it.  Training is required to conduct the appropriate evaluations and make the appropriate diagnosis.  Further training is required to assure that patients can be safely treated.  Associated medical conditions need to be recognized and diagnosed.  All of this came about as a result of a medical focus that was reemphasized with the advent of the DSM.  Prior to that there was an overemphasis on psychoanalysis and psychodynamic psychotherapy.  A darker Grey Box consisted of a brain full of psychoanalytic constructs and the diagnosis and treatment was overly dependent on this model.

DSM technology was a required step in refocusing psychiatry on medicine and the brain as an organ.  But that occurred 40 years ago.  During that time, psychiatrists diagnoses and treat people based on clinical experience and general patterns that they recognize in the course of their training and practice.  In some cases the DSM has very clear criteria that are very helpful - like the definition of a manic episode.  In other cases - like the difference between anxiety and depression there are problems.  The same patients can endorse predominately anxious symptoms one week and predominately depressive symptoms the next.  The severity of the illness can typically lead to a clearer diagnosis and that is most likely due to the fact that the boundary between a clinical case and normal is arbitrarily defined as impairment in functioning.  More impairment should lead to clearer diagnosis.  Better markers to classify illness and hopefully predict treatment response are needed.  The search for these markers is an active area of investigation.  Psychiatry will remain in the Grey Box without these markers and more clear-cut treatments that address the underlying biological changes.

A lot of pharmacological research was done during the DSM era.  There was a lot of discussion about neurotransmitter and receptor pharmacology and the implications for scientific treatment.  Like all science, receptor pharmacology and post synaptic cell signalling mechanisms do not stand still.  There are many theories of receptor and drug pharmacology that have stood the test of time.  With a focus on the pathological nobody could hope that drugs that were often accidentally discovered would lead to highly effective treatments or a more comprehensive theory of mental illness or normal brain  function.  Clinical trials of psychiatric drugs and studies of pharmacology and physiology are are also limited by research subject heterogeneity.  That is a problem with research on any complex polygenic illness.  In the case of pure mental  illness where any medical cause has been ruled out, the DSM criteria alone are a poor filter for selecting homogeneous populations for research.

Drug and psychotherapy research in the Grey Box have both suffered from treatments being applied to heterogeneous populations.  There is no researcher that I know who thinks that any two people with a DSM diagnosis are similar to the point that drug or medication response would be high or necessarily reproducible.  Apart from the diagnostic problem, the DSM suggests homogeneity in a context where any seasoned clinician knows differently.

The Clear Box is the goal here.  The knowledge needed to get to this box is much more comprehensive.  It recognizes brain complexity and the importance of the conscious state rather than just a collection of DSM descriptors. Despite the fact that many of the basic mechanisms were elucidated over 40 years ago neuroscience has detractors just like psychiatry.  A common strategy of neuroscience detractors is to take either a research finding or a media quote and "debunk" it with fanfare in the popular media.  Ulterior motives are often suggested for connecting neuroscience primarily with psychiatric disorders.  Many of these detractors depend on their own characterization of the original research and the cultural phenomenon of piling on with negative criticism to score what appears to be a victory with the vocal and like minded.  They use the same strategy in claiming that mental illness or addictions are "not diseases" like "real" diseases - despite the fact that the general population considers them to be equivalent.  I find nothing compelling about critiques of ongoing science and medicine by the unqualified.  The main problem is that the people truly qualified to produce the criticism are ignored in favor of what amounts to unscientific criticism.  There is a secondary problem with the proliferation of journals, especially opinion pieces rather than scientific papers.  
                                   
Another interesting thought that I had about the Clear Box is that many people have no difficulty at all in recognizing that machine intelligence is improving and that at some point it might exceed human intelligence.  They don't seem to have any problem in figuring out whether a computer may have negotiated the Turing Test and seem indistinguishable from another human being.  Many people seem to have difficulty recognizing the computational capacity of the human brain and the result of that complexity.  Despite some philosophical arguments - that is a possible reason for not seeing the Clear Box as the preferred state of brain knowledge.

I have tried to point out many times that one key element of the  mischaracterization of neuroscience in psychiatry is a basic lack of understanding of science.  Science is a process and a dialogue.  Medical science is more of a process and a dialogue than physical science - the processes involved are more complicated and the experiments involve proportionally fewer relevant variables.  There are no differential equations based on a few variables that explain how the brain works.  Entire blocks of research can end up partially true or a dead end.  That does not mean there is some grand conspiracy - that just means it is time to move on to a new paradigm.

KFF / Washington Post Survey Of Opioid Users

The Kaiser Family Foundation and the Washington Post have released a survey of prescription opioid users to the general public.  Reading through this survey and the accompanying explanations does not seem to match a few realities about the ongoing opioid epidemic.   Some important dimensions of addictive drugs are left out.  It is not  clear to me who designed the survey.  My only intent here is to critique it from the standpoint of an addiction psychiatrist and the current literature on what may have been more comprehensive questions.  The key dimension with opioids and any other potentially addictive drug is that a drug is being prescribed and a certain part of the population will over administer as a result of their biology.   The exact percentage of people with that tendency is unknown.  After reading through the survey results, this survey suggests the number of people is about a 30% - but there are some red flags.  Other literature suggests that the number is lower. The current opioid epidemic correlates with wider availability of these medications.

In order to understand the right questions to ask in a survey to detect problems with opioid use a brief review of the reinforcing effects of opioids are in order.  On the positive reinforcing side many people feel and intense euphoria with first use.  Many report increased energy and a sense of well being. In some cases people feel that they are thinking more clearly and in the extreme that their personality has been transformed.  Many people report that they feel like they have been transformed into the person they thought that they could always be.  All of these perceptions of the effect of opioids are highly reinforcing of future use.  It also highlights the problem when opioids are given for minor injuries in that a susceptible population is being exposed to these effects.  Another area of concern is post operative use.  A significant number of people continue to take opioids long after surgical procedures are done and wound healing is accomplished.

Another source of positive reinforcement is what has been considered self medication.  When a medication has the properties noted in the previous paragraph, it can take on magical qualities.  In American culture illicit drugs and opioids in particular take on magical qualities.  They are seen as the silver bullet for acute and chronic pain - when neither case is true.  When that belief is widespread  and the medication reinforces its own use - people begin to use it for insomnia, anxiety, depression, and as a general solution to stress. Some people will report that they just "don't want to feel anything" and will take enough of the drug to do that.  Taking the medication for these secondary effects can also reinforce use and lead to escalation of the dose.

Negative reinforcement is another aspect of addictive drugs.  In the case of negative reinforcement, the frequency of any behavior to decrease the response to an aversive stimulus increases.  With opioids the aversive stimulus is opioid withdrawal and the early symptoms are associated with cravings to use opioids and continue the addiction.  During that phase of addiction there is typically a tolerance to the euphorigenic and other positive reinforcing effects of opioids.  People are using opioids at this time primarily to prevent withdrawal but now the withdrawal has a host of associated effects like insomnia. anxiety, and depression that also must be avoided.  

That landscape of addiction, tolerance, withdrawal, positive reinforcement and negative reinforcement does not make this an easy problem to study.  There is an even larger problem and that is that decision-making is compromised in the direction of continuing the addiction.  That translates to dishonesty about use and in many cases dishonest behavior necessary to acquire and use drugs.  That dishonesty in the service of addiction is a major problem in studying addiction and providing clinical services.  It is the reason for toxicological testing, collateral information, and establishing sober environments with no access to intoxicants.  Any survey of patients with potential addictions should address how this issue has been handled in the sample.  Studies have been done on the predictive value of specific behaviors with opioids like purposeful oversedation, lost prescriptions, mixing alcohol with opioids, early prescription renewals, etc. but many of these stuides also depend on self report.

How does the KFF/Washington Post survey do?  First off the random sample is a combination of people using prescription opioids (N=807) or in the household where a person uses opioids (N=187).  The indication for opioid use is chronic noncancer pain.  The threshold was using for two months in the past 2 years.    Only 55% of the respondents were currently taking opioids.  The study was all done by telephone interview.  The respondents ranked prescription painkiller abuse as a serious problem (84%) and only slightly less serious than obesity, cancer, heart disease, alcohol abuse or heroin abuse (89-95%).  The lowest ranking of seriousness in that category was heroin abuse at 89%.  25% of the respondents began taking opioids for postoperative pain and 44% for chronic pain.

The section on motivation for using opioids indicated that pain relief was the major reason people were taking opioids and 92% or people ranked pain relief as either "very well or somewhat well".  Secondary reasons included dealing with stress, to get high, or to relieve tension (12-34%).  Of the secondary reasons getting high has the highest ranking of 34%.  There are several chronic pain studies that suggest that for chronic neuropathic pain - the relief from opioids is on par with pain relief from non-opioid medications for the same application.

Physicians did not get rated very highly in the survey with only 2/3 of them warning patients about the addictive potential of opioids or talking about non-opioid strategies for treating pain.  Only 1/3 of physicians had a plan to get people off opioids.  Physicians did better in terms of warning patients not to use alcohol concurrently with opioids and discussing side effects but only slightly better in terms of advising patients on keeping opioids out of the hands of others.

In medical practice, especially with electronic health record systems there is often an emphasis on pre-existing alcohol or substance use disorders.  The closest this survey comes is to ask about the number of alcohol drinks per week.  About 22% of respondents had more than one drink per day.  There is a lot of room on the high side.  There is also a dissociation between known addictive disorders and opioid prescriptions.  Many physicians believe that people with a known addictive disorder to a non-opioid including alcohol can control their use of opioids for pain.  They are often reassured by these patients who tell them that they have never had a problem with opioids.  

Only 18% of respondents had difficulty getting their prescriptions refilled.  That contrasts with the 1/3  of patients taking the medication to get high.

The degree of polypharmacy in the sample was striking with 32% taking 7 or more prescription drugs and 25% taking 4-6 prescription drugs.  Slightly over half of the sample were taking medications for insomnia, depression or anxiety.  Benzodiazepines and z-drugs were not specified.  The survey did ask about alcohol use while taking opioids and it is a clear problem.  In addition practice it is common to see patients who are using benzodiazepines and z-drugs with opioids.   It is also common to see people taking one, both and both in combination with alcohol.  In addiction practice it is important to determine if anxiety, depression, and insomnia are primary, caused by the addiction, or associated with chronic intoxication or withdrawal states.

On the specific question of risk of addiction 2/3 of respondents said that "The benefits of pain relief outweigh the risk of addiction."  One third of the sample said they were dependent on the drugs and would find them hard to stop.  When that question was rephrased with the description "addicted" 23% thought they were addicted to the painkillers.  Of the respondents who thought they were dependent or addicted - 1/3 sought treatment and 2/3 did not.  An interesting study might look at videotapes of the informed consent procedure and what information the patient recalls  after that procedure.  My experience suggests that a large percentage of people who are actively using opioids and alcohol do not recall what was said in the initial consultation by comparison with the documentation.

The survey attempts to parse blame  for the prescription painkiller epidemic and in that series of questions the groups ranging from most to least blame (61% to 15%) were ranked the patients themselves > doctors > drug companies > government > hospitals > law enforcement > pharmacies and pharmacists.  The key elements here are wider access to opioid medications as a result of an initiative to treat chronic pain and a movement away from gatekeepers.  

Given the limitations of a survey, I thought that the self assessment of the number of people who though they were dependent or addicted to painkillers was striking.  The number  of people seeking treatment though low is much higher than what has been estimated using other methodologies like the NSDUH survey.  It may suggest that survey technologies alone or in combination with other corroborative methods may be useful in further studies of this phenomenon.  One of the real questions out there is the number of people in the wild who are at high risk for the initial highly reinforcing properties of opioids.  If I had to guess, I would put that number at about 40% of the population.  There is a significant and slightly smaller group who get immediate negative effects and do not tolerate opioids at  all.  By definition, there may be a safe third portion of the population who can benefit from opioids with very low addiction risk.  Clearly defining that population, hopefully with biological markers would have a significant impact on the problem of addiction to opioids.  It would also have implications for a more elaborate diagram of the neurobiology of opioid addiction.

For physicians the problem is as clear as ever.  The vast majority of this sample (95%) got prescription pain relievers to alleviate their acute or chronic pain and 1/3 end up using the drug for other reasons including getting high.  That is due to the inherent properties of addictive compounds.  The practical problem is how to address that risk in medical practice.

Thinking and Shoveling the Snow

I got a late start today.  It was 1:30 in the afternoon but the sun was already low in the sky.  That violates one of the cardinal rules of snow shoveling.  If you are  shoveling light snow  and can get most of it up off the concrete - the sun will do the rest of the work and melt it off.  If it is too cold to melt on a dark surface sublimation can occur and it will transition directly from a solid to a vapor.  At this temperature and sun angle - I would be lucky to get 2 hours of melting.

One of the other cardinal rules of snow shoveling is that timing is everything.  I was up briefly at 7AM today.  It was still dark out, but there was plenty of activity in the neighborhood.  People shoveling, snowblowing, and plowing.  It was still snowing lightly at the time.  If you clear off the snow too early, there will be another inch or two of snow on top of your concrete.  If that happens consistently you might not see concrete again until the spring thaw.  I looked around and that had happened to several neighbors.  I also noticed that one of my neighbors had cleared off about 90% of the heavy snow from my driveway with his snowplow.  I am very appreciative of that.  At a psychological level it is a mixed blessing.  In my 20s, 30s, 40s, and even 50s I was a snow shoveling machine.  I would attack any depth or distance of snow with a thin steel scoop shovel and dispatch it as fast as I could.  Now I am becoming the old guy down the street who might be overdoing it.  Maybe they are right - decreasing snow shoveling vigor may be just another sign of heading toward decrepitude.

I have the inevitable associations to learning how to shovel snow from my father.  The theory of extending the shoveled surface out onto the grass for an inch or two so that any run off does not pool on the concrete and freeze.  Today for the first time, I realized why we used steel scoop shovels with short handles.  These were the shovels my old man used to shovel coal into a steam engine locomotive boiler when he started out as a fireman on the railroad.  He let me watch him once in a switchyard near our house.  I was only 5 or 6 at the time, but he was shoveling coal the size of softballs into that boiler.  You could only do that job with a light steel short handled shovel.  I have the usual associations about knowing my father for only 16 years or less than half the time I knew my father-in-law.  Today I had the thought that all of my interactions with and reactions to my father were the product of a brain that was 10-15 years away from neuroanatomical maturity.  What would it have been to know him as a mature adult?  How has that affected me?  If I had a son myself - what would I try to pass on to him about snow shoveling?  At this point - not having a son I will never know.  The snow shoveling knowledge of the Dawson clan dies with me.  Even the most liberal college will probably not have a "Snow Shoveling 101" for the curious.

I drag out the snowblower and fire it up.  There is still an uneven 3 - 8 inches of snow to clear up.  The snowblower is about 20 years old.  It was a birthday present to my wife.  Believe it or not she requested it - but she might have not disclosed her real motive for that.  She was probably concerned about me throwing snow around with that scoop shovel like a blender and thought: "OK - how long can he keep doing that before something bad happens?"  She tells me to use the electric starter so it doesn't freeze up and I oblige.  I start snowblowing in an arc over 90 degrees back and forth blowing all of the snow to the eastern side of my driveway.  I realize that my driveway alone has more area than all of the concrete that my father and I used to shovel at the family home.  I wish that I knew more about graph theory.  The pattern that I use to shovel the driveway could probably be optimized by graph theory.

After that I get out a shovel.  It is no longer a scoop shovel.  It is an  all plastic shovel with a 90 degree bend in the middle.  They sell a lot of these shovels these days.  I am very skeptical of the  mechanical advantage, but it does allow a more erect posture in the process.  I am using it because I have to shovel on a textured concrete sidewalk and can't use steel shovel or a snowblower without scratching the surface.  I shovel a scoop wide margin up the right hand side of my walkway and then come back cross cutting the width of the side walk.  Swing the shovel from left to right and throwing the snow off the end - the same way my father used to shovel coal.  It takes 30 swipes and I am clear.  I check my heart rate and it hasn't budged.  The last time I shoveled a week ago it was up about 20%.  As I was shoveling I thought of an exercise device that would mimic snow shoveling.  In many ways it is a whole body work out.  Kind of like a kettle bell at the end of a longer handle.

I also fantasize about high tech approaches.  For some reason I have become more and more fascinated with tractors.  I was watching the Discovery Channel late one night and saw a small Swedish tractor that was designed to clear airport runways.  They were using it to build an ice castle.  It was designed to eject large amounts of snow directly over the front of the drivers cab.  I think about what a great time it would be to drive this tractor all day long - moving tons and tons of snow.  I conclude it is a narcissistic snow shoveling fantasy - a probable reaction to my concerns about becoming a less competent snow shoveler.  Still it would be nice to drive that tractor even for a day or two...

I come back to the main driveway and decide that I need to go over it with a shovel it see if I can expose more of the concrete surface to the sun.  This time I create several shovel widths down the west side and cross cut from west to east about 60 times.  I look at my activity monitor and notice that it has only taken about 3000 steps to do the entire job.  I have the thought that with the exception of some time I spent in East Africa, I have been shoveling snow for 50 years.  I also recall that in the famous Halloween blizzard/storm of the century my father-in-law and brother-in-law shoveled a foot of snow away from my old Chevy Chevette, crawled under it, and dropped in a new starter motor.  It was parked on the street at the time, it was nighttime, and it was 5 below.  They had to run a hundred yards of extension cord out to the street to do the work.                    

You might say that I am emotionally connected to the snow and shoveling it.  There is a lot of meaning there and in my 50th years of shoveling it - that meaning is not diminished.  It might explain why I have no interest in moving to warmer climates. Thinking a lot about things has always worked for me.  Shoveling snow is time to think and reflect.

I occasionally think of the limitations to all of this thinking.

Driving motorcycles is just one example.  I stay off of them.

Alcohol Overuse After Gastric Bypass Surgery

Alcohol use disorders after gastric bypass procedures are a significant complication of this surgery.  I typically see people who have developed the disorder after the gastric bypass procedure.  The majority of those procedures these days are Roux-en-Y (RYGB).  The surgical mechanics of RYGB are widely available and I am not going to review them here.  This post is about how the procedure can change a person into a problem drinker endangering both their health and in some cases leading to substantial weight gain after initial losses from the bypass procedure.  Although there are other surgical techniques used for gastric bypass that also lead to this complication RYGB is the most common technique and is more likely to be studied.  In the figures above, blood alcohol levels are determined in individuals who had undergone RYGB surgery after ingestion of alcohol.

One of the well known principles in addiction medicine is that overuse of any potentially addictive substance generally follows pharmacological principles especially as tolerance to a drug develops.  Other factors such as economics, whether a drug can be used by a particular route, and biologically determined sensitivities to drugs can modify that basic concept.  To illustrate, most current opioid users with addiction problems started by using prescription painkillers.  They may have modified the original prescription pills by crushing them and either smoking or snorting them.  In some cases, they crush the pills, dissolve them, crudely filter them and inject them.  In this case they are trying to optimize the time to peak drug concentration Tmax and maximum drug concentration Cmax for maximum effect.  In the case of alcohol, it is generally too dangerous to use by the inhaled or intravenous route.  The effects are limited by absorption and elimination by zero order kinetics.

The graphics at the top of this page are from reference 1. It shows the results of blood alcohol concentration of 5 RYGB patients after drinking a solution of 40% vodka and orange juice calculated to contain 0.3 gram per kilogram body weight. The vodka and orange juice mixture was adjusted to contain a 50:50 mix of vodka:orange juice. Mean dose of ethanol given was 26.9 ± 2.3 grams or about 2 standard drinks consumed over a period of 5 minutes. On the graphs alcohol concentration is given as mg/dl. In the US, the current legal driving limit is 80 mg/dl or 0.08%. The researchers decided to look at the time from 0-10 minutes apart from 0-60 minutes because previous work started the measurements at 10 minutes.  The other point to notice in these graphs is that there is no control group.  That is unfortunate given the variable methods (alcohol dose and consumption time) that are used to determine the pharmacokinetics of alcohol in research papers that look at this question.

A comparison with control subjects in the literature can be done, but I could not find any studies that used a dose of 0.3 g/kg of ethanol.  Many studies used a dose of 0.6 g/kg.  The study used in the comparison below used a dose of 0.8 g/kg ingested over 30 minutes.   Comparing Tmax and Cmax for the study on RYGB patients to a study of 12 healthy male controls shows the following differences:

	Male controls (n=12)	RYGB patients (N=5)
Cmax (mg/dl)	106	138.4
Tmax (min)	60	5.4

Experimental differences aside. the Cmax and Tmax for alcohol in the RYGB patients are markedly different.  The time to peak alcohol levels was only 5.4 minutes in the RYGB group and at that time the average Cmax easily exceeded the legal driving limit on what amounts to 2 standard drinks.  Although the study did not correlate the rapid peak of alcohol with effects, they are readily observed by any clinician interested in how intoxicants affect the conscious state of the patient.  People typically tell me that they feel immediate intoxication or in some cases blackout.  The intoxication is a rapid sense of euphoria combined with an immediate cessation of negative mood states.  In the case of blacking out, this is a frequent end point with severe alcohol addiction.  Many people are self professed "black out drunks" and that is their preferred endpoint of acute intoxication and the goal of subsequent drinking sessions.  These states are highly reinforcing for susceptible people and probably explain the greater than expected occurrence of alcohol related disorders following RYGB surgery.  Looking at the prevalence of alcohol use disorder (AUD) before and after RYGB surgery, Mitchell, et al found that 8% had AUD within the 3 year post op period including 48% who had no prior history of AUD.  Including a more permissive screening tool the number increased to 18.4% and 40.6% respectively.  A previous study  showed that the prevalence of AUD symptoms was greater in year 2 post gastric bypass surgery (9.6%) and was associated with a number of preoperative variables including RYGB, male sex, smoking, and regular alcohol consumption before the procedure.

The studies that look at the prevalence of alcohol use are interesting.  From the perspective of an addiction psychiatrist who only sees patients selected for addiction, observing the effect of scale is significant.  As an example, the patients who I see with this problem are predominantly women and practically all of them did not have an alcohol use problem prior to surgery.  In many cases they did not drink alcohol.  Practically all had undergone RYGB but there were also people with other bypass procedures. 

An additional research question has been whether the anatomic changes in RYGB lead to changes in the brain and central nervous system that changes addictive behavior.  The model used for these investigations have been obese rats that have undergone RYGB and intravenous self administration of alcohol and drugs.  That model would eliminate pharmacokinetic considerations from oral administration with rapid increases in plasma concentration in a short while.   Rats with RYGB self administer intravenous alcohol and opioids at a higher rat than rats that have not had gastric bypass surgery suggesting a centrally mediated mechanism more independent of gut absorption (5,6).  One set of authors (5) proposed that in obesity there is blunted dopamine and ghrelin signalling.  They make the case that leptin and ghrelin both affect dopaminergic signalling in the reward system. (see diagram - click to enlarge).  

Despite being well known to eating disorder and addiction specialists, I don't think the phenomenon of alcohol overuse in gastric bypass patients is well known.  It has implications for informed consent for this surgical procedure, some risk factor modification, and follow up.  It also may have implications for the diagnosis and treatment of alcohol use disorders.  As an example, binge drinkers and blackout drinkers are a known subset the population of people with alcohol use disorders.  Does this group have any similarities with the population of RYGB patients who develop alcohol use disorders?  What would pharmacokinetic studies of alcohol in this group show?  If a profile of peptide hormone changes in the RYGB group is defined - should that be studied in binge and blackout drinkers as well?

These might lead to useful endophenotypes for alcohol use disorder that could lead to treatment interventions.

Brandolini’s Law

There was an informative editorial in Nature this week by Phil Williamson - a scientific expert on ocean acidification.  I like the concept of bullshit and have referred to Professor Harry Frankfurt's classic essay on it many times.  I was not familiar with Brandolini's Law until I read the essay.  Simply stated:

Brandolini’s Law: “The amount of energy needed to refute bullshit is an order of magnitude bigger than to produce it.”

It is also more simply known as the The Bullshit Asymmetry Principle.

Williamson uses a political example from a libertarian web site.  The central piece of that article was that ocean pH was not decreasing and that climate change would lead to reduced carbon dioxide in the oceans.   Because the climate is not changing there is no worry that the ocean pH would change.  The original publication denied Williamson's rebuttal.  An opinion piece in a professional journal led the author of libertarian piece to write online that his work should be "squashed like a slug".  Nothing like elite scientific dialogue is there?

In the UK there is apparently a press watchdog called UK Independent Press Standards Organization (IPSO).  Williamson filed a complaint with them about the factual accuracy of the piece and is awaiting their verdict.  He goes on to illustrate how Brandolini's Law comes in to play in this situation.  The original author these days can essentially be anyone from a journalist to a blogger.  He points out that online journalism "seems to be subject to few if any rules."  That leaves anyone in the position of responding to a factually inaccurate claim at a distinct disadvantage.  There may not be any formal complaint procedure and there is probably no editorial hierarchy.  Many web sites count on bloggers and writers to produce content that they can attach advertising to and this content seem to have very little oversight in terms of accuracy.  Much of this content on social web sites makes up what has been referred to as fake news.

Williamson's position is very clear.  He thinks that these inaccuracies need to be responded to and corrected.  He accurately points out that the audience for the correction is not the authors, but readers who are interested in accuracy and science.  I don't think that the division is that clear for a number of reasons.  A large number of people really don't care.  They are involved in the emotion generated by the issue and don't make decisions based on facts.  That general attitude is promulgated by the political process in most countries.  This is rarely a rational discussion of the main issues of the day.  I think this goes a lot deeper than generating rebuttals.  There needs to be education on the difference between science and everything else.  A good example is Creationist based rhetoric and the denial of evolution.  Creationist advocates do not seem to recognize that they are engaged in a process that is nothing like science and therefore cannot scientifically prove anything.  They fail to recognize the basic issue that science is a process and not an immutable collection of writings written by ancient prophets and subject to many interpretations.  That failure of recognition also leads to a failure to recognize that they are  completely outside the field of science. They fail to recognize where they are and that the best critics of a scientific theory are the scientists in the field.

This failure of recognition is much wider than Creationists.  Journalists produce many examples, not the least of which is a consistent bias against psychiatry.  That bias is present whether or not there is editorial oversight.  A great example is the journalistic tendency to propose what psychiatry is and then proceed to attack that straw man.  And interestingly these outsiders with no training in medicine or psychiatry are often joined by insiders pushing the same arguments.  In one case a prominent journal editor came out and endorsed an anti-psychiatry book, proclaiming legitimate criticism when in fact the book was rhetorical.  I would not presume that medical editors are without common biases.  There are many forces producing misinformation.

I diverge a bit with Williamson's approach on refuting the misinformation and hoping for the best.  I think that there are additional considerations.  One thing is very clear - the head-in-the-sand approach taken by physician professional organizations in response to misinformation is clearly not a good idea and is sure to lose in the current propaganda war of misinformation and political corruption.  If there is a lesson with the current Presidential campaign it is that there is a very small margin between a typical fact less campaign and one where anything at all can be said whether it is true of not - and nobody seems to care about it.

That is foreboding for all levels of public policy, especially when the political spoils includes being able to appoint agency heads with not only a lack of basic footing in science but also a lack of knowledge about what constitutes science.  For the country to run and maintain some standards in science, technology, and engineering there needs to be a basic understanding of these fields in all branches of government and at the highest levels.  There is currently no better example of what happens when the unscientific manage the store than what has happened to American medicine.  We are not only cursed by work rules that are made up as we go and have little to do with the practice of medicine, but we we have to live with pseudo-scientific management practices that affect our work flow and and detract from the lifelong task of learning the science of medicine.  A few strategies I can offer as a blogger follow.  I also have additional strategies that I am going to keep to myself until just the right time.

1.  Don't feel compelled to engage - Twitter is an excellent example of how this principle is applied. Suddenly you are being given the third degree by some poster. That turns into misinterpretations of your statements and positions and before you know it personal attacks.  But it doesn't stop there. A new account pops up and mysteriously continues the attack.  Call them trolls or whatever you like but recognize the tactic. They don't really care what you have to say and are quite happy to waste your time.  Don't engage. Twitter gives you the option to block them and that works the best.

2.  Present the facts but counter the rhetoric - It is important to recognize the common forms of rhetoric without being pedantic.  The best way to do that is by pointing out the erroneous aspects of the argument and the overall form without naming the fallacy.  This sounds easy and it should be - but physicians and psychiatrists seem to be spellbound at times by the simplest arguments.  One common example is anytime a business executive shows up and talks about "cost effectiveness" - everybody shuts down.  Nobody seems to understand that this is just business rhetoric.  It should be as obvious as the fact that with 30 years of intensive management and "cost effectiveness" - per capita health care costs are 40% higher than the country with the next highest per capita expenditures and health care is certainly no better.  In the case of treating mental illnesses and substance use disorders it is much worse.  Somebody needs to stand up and say: "We are doing our part - when are you going to start to do yours." or "Get out of the way and let us do our work." or "Give us the resources to provide the adequate service or shut it down."   Rationing is clearly a very ineffective and costly way to provide health care services.

3.  Recognize bullshit no matter where it comes from -  Many of the arguments for health care reform are just plain erroneous.  And why wouldn't they be.  We now have a continuous supply of what are essentially blogposts on the front of our most respected medical journals.  How could anyone expect that 12 or 52 health care reform ideas each year for years would be worth anything?  All of the top posts that they have been implemented like the electronic health record, managed care as business intermediaries for government purchasers, pharmaceutical benefit managers, creating various financial incentives - have all been progressively worse ideas.  Sifting through the misinformation to correct what is false, what are lies, and what is bullshit is a tedious but necessary task.  As long as medical journals legitimize this constant stream of unscientific information - countering it will remain an onerous task.  The sources of bullshit go far beyond blogs and traditional journalism.

4.  Don't let anyone define you - A common strategy these days is that detractors tend to jump in and set the stage with false criticism.  It was easy to see this in political debates.  In medicine and psychiatry the same process happens and I have pointed out the dynamic on this blog.  I also posted a recent summary of how the release of the DSM-5 was a major source of misinformation, lies, and bullshit in 2015 but there are many more examples in psychiatry.

5.  Don't let the barbarians at the gate get you down - I tell aspiring physicians and aspiring psychiatrists the same thing - don't let the detractors or in these days trolls - get you down.  Psychiatry is a tough field because there will always be a lot of people blaming you for their problems.  This is where Brandolini's Law really applies.  There are numerous dialogues on web sites available where the game is to post as much misinformation, bullshit and lies about psychiatry in particular.  Entire web sites exist for that purpose.  Entering into that discussion and taking the opposite side of the argument can be more futile than the Law suggests.  It may take several orders of magnitude of effort and even then it may be futile.  The best approach is to just get the information out there in cyberspace in an independent forum where you know that it can be safely viewed.   That is one of the reasons that this  blog exists.

6.  The Internet is still the Wild West and that will probably never change in its current form - Williamson suggests that it may be possible to "harness the collective power of the Internet to improve its quality."  He suggests the global scientific community reviewing sites and rating them like film rating sites.  I am far less optimistic.  The first problem is the scope of that project.  The second would be consistency in ratings.  The third is that a rating in some sense is legitimizing.  It is a far better approach to ignore the ignorant.  The reality is that reputation protection web sites basically work by generating a lot of information designed to bury the obnoxious web site.  Most people find that if they contact a search engine about a web site that may be slandering them that they are met with a a relatively hostile response and a complete lack of interest in correcting anything.  That is true for even the largest search engines.  Google for example, clearly doesn't give a damn about your reputation.

7.  Brandolini's Law is a significant deterrent to keeping professionals engaged in educating the public - Physicians certainly find this out in a hurry if they decide to post a rebuttal in political or media forums that are populated by the ignorant, trolls, or those with a specific agenda.  That is more true of psychiatrists than any other specialty.  That has a dual effect of limiting feedback to those who might be interested and eliminating the most informed criticism.  It also has the added effect of adding professionals who may have legitimate criticism to antipsychiatry web sites where scientific criticism is clearly not the agenda.  It is a dangerous path of least resistance when legitimate professionals start posting on web sites dedicated to the destruction of the profession.

 These are just a few ideas about Brandolini's Law.  I did not write the most important one down and that is you can always just go off the grid.  Even then there are problems.  I talked with a psychiatrist about 10 years ago who was asked to give presentations at local churches on depression.  He eventually gave up because there were people in the audience who for various reasons were so disruptive that it prevented him from giving the interested people the information that they wanted.  Only psychiatrists could end up being heckled in church.  Bullshit can be presented in person just as easily as is can by typed online.

Williamson refers to a "rising tide of populism threatens the future of evidence-based government."  I don't think that we have ever had evidence based government in the US.  I see it as mostly a power dynamic here - influencing people by emotional ideas and shouting them down.

The only reason why that Brandolini's Law doesn't work in reality in the case of psychiatry is that at the end of the day, there are still people with severe mental illness - no matter who tries to deny it and a group of people called psychiatrists who are interested in helping them.  That is not necessarily enough to prevent the widespread demoralization of a profession.

My brother saw this post and commented that Brandolini's Law has "never been more true."

I reflected on that true statement and the continued widespread ignorance of science and came up with the following observation that might have been made by Casey Stengel:

"Good science cancels out bullshit and vice versa."

That probably captures why misinformation grows as exponentially as scientific information in any society.  It levels the playing field (to some degree) between the informed and the uniformed.

Is The FDA Contraindication On Bupropion Wrong?

Since moving to a strictly outpatient consulting practice, I have been amazed at the number of women who are taking bupropion despite the above contraindication.  I have probable seen 50 women who were under my care in this situation.  In other words, I did not prescribe the bupropion and before seeing this would not have considered prescribing against an FDA contraindication.  The patients I see often have additional contraindications including a history of seizures, sedative hypnotic drug withdrawal, or alcohol withdrawal.  Seizures are the final common pathway for this subset of contraindications.  I have never really observed a seizure from bupropion and the vast majority of the patients with the contraindications have never had a seizure.  I have certainly observed and treated seizures in inpatient settings and understand that there is a low but significant risk of mortality with seizures.  I have also not observed a significant complication of seizures, but at the time I worked in an inpatient hospital environment with rapid access to nursing staff, medications, and experts.  None of the patients that I have initiated treatment on with bupropion have reported seizures, but I was strictly following the contraindication as listed in the FDA package insert.

My dilemma in this situation is always whether or not to continue the bupropion, especially when the patient tells me that it is the only medication that has been effective for them.  Patients who are seen in their late thirties or later generally have been tried on numerous antidepressants from several classes and that complicates the clinical picture.  Most of them have never seen a  psychiatrist and all of the medication trials have been done by primary care physicians.  It is common to see SSRI and bupropion combinations initiated by nonpsychiatrists.   In my current capacity, I am not treating any of these patients long term.  I see them anywhere from 1 to 3 months and at that time they return to see their personal physician or psychiatrist.  I try to contact their personal psychiatrist about the issue but communication among physicians is often difficult to complete.

As I began to see more and more of these patients my first question was a scientific one.  I was aware of the the trials that lead to the decision about eating disorders.  There were all based on immediate release preparations rather than the sustained release (SR) or extended release (XL) versions.  It certainly is possible that I am only seeing the success stories and that the patients with seizure related complications never come to my attention, but the practice of prescribing bupropion to a population that the FDA considers high risk seemed to be on the rise rather than decreasing.  Is it possible that all of the other prescribers had also not heard of this complication.  I knew that most of the patients were never apprised of the contraindication.  I know that because I had them read the contraindication section of the package insert for themselves.  Most would say that nobody have ever told them about this especially the part about any prior diagnosis of anorexia nervosa or bulimia.  It is difficult to tell a 45 year old woman who had bulimia nervosa in college and recovered that the bupropion that she has been taking for the last 10 years without any side effects needs to be stopped because of this contraindication.  The psychiatrists I talked with all minimized the wording in the warning.  They ignored the part about "prior diagnosis".  In fact some initiated treatment as the patient was completing treatment in a specialized eating disorders program.

I turned to the FDA web site for additional guidance on the agencies definition of contraindication.  Was it as relative as these psychiatrists were telling me?  It turns out the definitions used by the FDA in package inserts are defined in the Code of Federal Regulations (CFR).  The section defining contraindications follows (p. 6 of 18):

(5) 4 Contraindications. This section must describe any situations in which the drug should not be used because the risk of use (e.g., certain potentially fatal adverse reactions) clearly outweighs any possible therapeutic benefit. Those situations include use of the drug in patients who, because of their particular age, sex, concomitant therapy, disease state, or other condition, have a substantial risk of being harmed by the drug and for whom no potential benefit makes the risk acceptable. Known hazards and not theoretical possibilities must be listed (e.g., if severe hypersensitivity to the drug has not been demonstrated, it should not be listed as a contraindication). If no contraindications are known, this section must state "None."

People seem to think that there is room for interpreting this definition of contraindication and it does beyond the APA Ethics Committee.  I got the same opinion from an attorney.  I also consulted a national expert on eating disorders.  That expert opined that the contraindication was relative in both  a history of eating disorders and acute eating disorders.  The expert also had inside knowledge of why the FDA might have issued the contraindication in the context of scant evidence.

I have previously posted that the FDA seems to exhibit some biases when it comes to psychiatric disorders.  In some cases they seem to not consider the severity of the the disorder in considering contraindications.  There should be no question that eating disorders and depression are very serious conditions, serious enough that therapeutic options may include some risk.

In the meantime, I have decided to take some action.  The FDA web site is a wall with no way in for people like me with a legitimate problem.  I sent letters out to the US Senators from my state to try to find a way in.  My goal is to get this contraindication taken out so it reflects current clinical practice and the experience of depressed patients with both a past history of an eating disorder or an eating disorder.

If you are a person with that history or a psychiatrist who prescribes bupropion in the face of this contraindication, please join me in advocating for this change.
