Norovirus - Avoid It If You Can

 

Norovirus is an Increasing Problem

Norovirus is a non-enveloped single strand RNA virus.  One of the critical features of Norovirus is infectivity.  Infected individuals secrete the virus in feces, saliva, and oral mucus.  Virus can be detectable in the saliva for up to 2 weeks after infection even though most of the guidelines for food preparers suggests that they can go back to work 2-3 days after the acute illness has passed.  The infective dose for Norovirus is as little as 18 viral particles (1).  An infected person is excreting billions of these particles. For comparison, influenza virus requires a dose of about 1.95-3.0 x 10³ infectious particles, and most common respiratory viruses including SARS-CoV-2 are on par with Norovirus. 

The clinical syndrome develops rapidly after exposure resulting in abdominal cramping, vomiting and diarrhea.  It creates significant mortality and morbidity causing an estimated 213,000 deaths world-wide (2).  In the US 900 people die per year out of 21 million infections. Most of the fatalities occur in the elderly and immunocompromised. Rapid fluid loss and dehydration is most likely a causative factor especially in the case of pre-existing medical problems. There is a bias toward advising all people like they are healthy young adults and that this syndrome is a self-limited 2-3 day episode of stomach flu.

There is an asymptomatic carrier state with anywhere from 11.6-49.2% of measured populations carrying the virus. This also extends to 1-3.4% of food handlers.  Humans were previously the only known reservoir for this virus, but a recent review looked at modern data and concluded that it may be a reverse zoonosis with human to animal transmission in lab animals and the wild (3, 4). 

Outbreaks of the virus are getting more common especially in environments where there is close contact and contact with contaminated surfaces like schools, universities, elderly homes, and cruise ships.  In the US there are about 2,500 outbreaks per year and poor granularity in terms of geographic locations. In other words, unless a local news channel picks up the story of an outbreak – you probably will not know until you get there.  The distribution of outbreaks over the calendar year for the last 4 years is given at the top of this post.  Outbreaks tend to intensify in the winter months where there is more aggregation.   

The most common advice given to prevent Norovirus infection is hand washing and cleaning contaminated surfaces.  The virus remains physically stable in pH 3-7 condition and temperatures up to 60 degrees C (140 degrees Fahrenheit) but that conventional wisdom may not be enough.  The virus is aerosolized presumably by coughing, sneezing, and toilet flushing and has been detected in the air around hospitalized patients (8). The particles detected were in the droplet nuclei/aerosol range but that may be an artificial dichotomy (9).  The main point in this research is that the droplets detected contained sufficient virus to cause infection. Current CDC precautions for Norovirus do not include masking except where there is a risk of “splashes to the face during the care of patients, particularly among those who are vomiting.”  This is reminiscent of the reluctance to declare respiratory viruses including SARS-CoV-2 and influenza airborne. 

6.6% of the US population are immunosuppressed based on taking immunosuppressant drugs or having a health condition that affects immunity and that number is increasing (10).  Women are more likely to be affected than men. In addition to the immunocompromised - 39% of the population has at least one serious chronic illness any number of which can affect innate immunity (11).  In addition, many of these diseases or their management can end up compromised by severe acute gastroenteritis.  Common examples would be blood glucose management in diabetes mellitus and electrolyte and fluid management in hypertension, arrhythmias, and renal disease.  Since 42% of the population has 2 or more chronic conditions it is highly likely that recommended management of rehydration will need to be personalized to that patient.  

There are also nebulous recommendations about the quarantine necessary following an episode of this illness.  The CDC web site provides an example, in order:

“Most people with norovirus illness get better within 1 to 3 days; but they can still spread the virus for a few days after.”

“You can still spread norovirus for 2 weeks or more after you feel better.”

“Stay home when sick for 2 days (48 hours) after symptoms stop.”

Apparently, Norovirus has been detected in saliva for up to 2 weeks after infection – leading to this mixed recommendation. There is some additional information at a public health link – but not much more. This link has interesting information on clinical criteria without biological confirmation that a probable Norovirus outbreak is occurring. In a 2013 review, Norovirus was the second most common infection disease outbreak affecting psychiatric hospitals (13).  This review looks at infection control procedures that may be unique to psychiatry as well as those that address the difficult to destroy nature of the virus.  It is resistant to common hand sanitizers and the need for contact cleaning with hypochlorite while be masked and gowned to prevent infection of staff.  The reference on the possible airborne nature of the virus also applies. A description of a psychiatric hospital with 4 previous Norovirus outbreaks and how that was stopped by a specific infection control program is also described (14).

That is currently the state-of-the-art on Norovirus. I have some additional information posted below.  The best defense at this point is to know that this is a highly infectious virus that is nothing to fool around with, especially if you are elderly, have chronic medical conditions, or are immunocompromised.  I don’t think it is my place to make specific rehydration recommendations because of the complexity I describe in the above paragraphs – but your personal physician certainly can.  No matter what you read – avoiding dehydration is the most important aspect.  Your physician can best describe how to do that given any other medical conditions. 

There are currently no vaccines or antiviral medications for Norovirus.  Vaccines are complicated by several factors discussed in this paper (15) that projected vaccine availability 5-10 years out from 2014.  Here we are 10 years out. Like the current SARS-CoV-2 vaccines early trials show a limited duration of immunity, but that can eliminate many cases in more vulnerable populations.

For 2025 – I decided to separate out my anecdotal experience from the published scientific data.   Readers of this blog know that my intent is generally to include it as additional relevant information and I have joked about trying to learn more about diseases by trying to get most of them.  That is no different with Norovirus.  The actual clinical syndrome I have seen many times dating back to my days as a Peace Corps volunteer travelling in East Africa.  It was referred to as “Traveler’s Diarrhea” and the theory was that it was caused by “enterotoxigenic E. Coli.”  Various remedies were suggested including Pepto Bismol (bismuth salicylate) or a prophylactic course of sulfamethoxazole/trimethoprim (SMX/TMP) – an antibiotic that I subsequently prescribed many times as an intern and resident.  

All Peace Corps volunteers were issued a medical kit and the two primary medications were a large bottle of Lomotil (diphenoxylate/atropine) and another large bottle of Benadryl (diphenhydramine).  So most acute diarrheal diseases were treated with Lomotil.  We also got IM cholera vaccines that interestingly were discontinued shortly after my Peace Corps tour because “they were more painful than protective.”  The only currently approved cholera vaccine is an oral vaccine.

My wife recently had a complicated course of appendicitis and there was concern about the possibility of an intraabdominal abscess.  As she recovered slowly from the surgery she had residual right upper quadrant pain and suddenly developed an acute illness again very similar to the appendicitis. I convinced her to go to free-standing emergency department where she was treated for nausea and rapidly given 1 liter of normal saline in less than 30 minutes. She was hypotensive and had a lot of vomiting and diarrhea in the hours before this assessment.  A CT scan of the abdomen was negative and a PCR test of a stool sample confirmed no C. difficile toxin and positive for Norovirus (see test panel below).

Returning home she recovered over the next two days – but I contracted it and am recovering on day 3.  I will post the symptom course in this note when I am fully recovered.  I will note that my wife has had 2 episodes of SARS-CoV-2 infections in the past 3 years and I did not get them from the airborne route but was masked and using a UV air cleaner at the time.  This time I was not masked – but I was using all of the CDC recommended contact precautions, the same UV air cleaner, and handwashing.

Sometimes it pays to be a hoarder. I found this book in my auxiliary library today.  It was sent to me by a friend who was attending Harvard Medical School when he heard I was definitely headed to Africa.  I regaled my Peace Corps colleagues with tales of possible infections in Africa. The most interesting section for this post is that it provides an anchor point for diarrheal disease classification in 1975. It lists invasive and enteropathogenic E. coli as the primary pathogens detectable by culture and bioassay or an assay set up to detect the toxin.  Epidemic viral gastroenteritis is attributed to Norwalk virus in the same book.  The name originated from immune electron microscopy of a viral particle identified as a causative agent in Norwalk, Ohio.  Episodic viral gastroenteritis at the time was attributed to rotavirus, duovirus, and orbivirus.

Supplementary 3:

I resumed working out on day #7 and have charted the symptoms using my invention of a malaise index.  Note that APAP here means acetaminophen that I take for symptoms that are generally caused by cytokines from the inflammatory response caused by viral and bacterial infections.  The index itself is included below the graphic of the course of the illness to explain what was rated.  For research purpose a Likert scale approach for every item would probably be used.  Even though the symptom descriptions are fairly basis - the underlying pathophysiology is not.  There are also some symptoms that I experienced that were not included like a sensory lack of taste for food.

Long Term Use of ADHD Medication and Cardiovascular Outcomes

 

 

I have several posts on this blog about prescribing ADHD medications with a goal of minimizing adverse psychiatric and medical side effects.  Like all medical treatments, close follow-up and monitoring is required to assure efficacy while reducing the risk of adverse effects.  To a trained physician it does not take much effort other than being rigorous in examinations and discussions with patients. In the area of ADHD, there is the frequent assumption that patients are young, healthy, and can probably tolerate medications better than older populations. With the increasing diagnosis of adult ADHD, all the comorbidities need to be carefully addressed and a recommendation of no treatment also needs to be considered.

Who have I advised against treatment? Older adults with obvious cardiovascular problems that are inadequately treated or controlled who may or may not have ADHD.  I do not really care if you are 60 years old and I think you really have ADHD, I am not going to start treatment if your blood pressure is not in good control or if you have other unstable conditions like angina, congestive heart failure, cardiomyopathy, or arrhythmias.

The commonest reason for not treating people was hypertension, measured by me in the office.  In some cases, there was an abnormal ECG showing a previously unknown arrhythmia. It can be difficult to tell a patient that you will not treat them because of a medical condition – but that is just the way it is.  Even if treatment is started – blood pressure monitoring needs to occur at every visit.  In some cases, I recommend that the patient purchase a home blood pressure monitor and send me the results.  Referring the patient to their primary care physician or cardiologist is useful to let that physician know that their patient wants stimulant treatment and provide feedback on what your assessment of their cardiac status was.  It is common for physicians prescribing adequate does of antihypertensives to not know that their patient is still hypertensive. It is always clear that the decision to prescribe stimulants is made by me and does not depend on the opinion of another physician.

White coat hypertension (WCH) is not an exception.  WCH is the idea that people get hypertensive related to the stress of being in physician’s office.  Conventional wisdom was that resolved when the patient left the office and therefore this was a being condition. The problem with that assessment is that it depends on knowing that the blood pressure did normalize away from the office.  That lead to a more modern definition that required ambulatory blood pressure measurements away from the office and subsequent more detailed definitions. As an example, the European Society of Hypertension recommends the following:  subjects with office systolic/diastolic blood pressure readings of ≥140/90 mm Hg and a 24-hour blood pressure <130/80 mm Hg.

In the most recent review, the authors do an excellent job pointing out some of the flaws in the early research that led to no significant differences between subjects with WCH and controls.  The control subjects often had cardiovascular disease or were treated with antihypertensives.  They also make the distinction between white coat effect (WCE) and white coat hypertension (WCH). WCE is defined as “an alerting reaction working through reflex activation of the sympathetic nervous system.”  A standard research technique to assess stress effects on blood pressure is to ask subjects to do mental arithmetic and it generally leads to a blood pressure effect like what the authors describe in this paper of 20 mm systolic or 10 mm diastolic.  The authors provide guidance on differentiating the various combinations of white coat hypertension and hypertension as well as providing guidance for future research.  In the office for the purpose of prescribing stimulants the key question is whether there is a white coat effect, white coat hypertension, and whether it occurs in the context of treated or untreated hypertension. Short of ambulatory blood pressure measurements other sources can provide some additional guidance.  Access to the electronic health record can show long term trends.  If indicated - I would not hesitate to suggest that the patient consult with their primary care physicians or hypertension specialist for ambulatory BP measurement.         

Studies have shown that patients who continue to exhibit a reactive blood pressure problem at home have similar cardiovascular risks to hypertensive individuals.  On the flip side, I have assessed many distressed patients in inpatient settings who were normotensive.  Based on this experience, I do not dismiss elevated blood pressure readings in the office especially if I am going to prescribe a medication that may elevate blood pressure.  

That brings me to the paper that led me to write this post (1).  This is a nested case control study of registry data in Sweden that looked at 10,388 cases of ADHD and 51,672 matched controls (aged 6-64 years old).  Exclusion criteria included pre-existing cardiovascular disease, previous use of ADHD medication, and emigration or death before baseline (defined as day of first ADHD medication or diagnosis – whichever came first).  This study design basically looks at the defined illness (in this case ADHD) and then matches the selected cases to controls from the same cohort – in this case up to 5 controls without known cardiovascular disease.  The exposure in this case was ADHD medications including study period, including methylphenidate, amphetamine] dexamphetamine lisdexamfetamine, atomoxetine, and guanfacine.  The last two medications are nonstimulants and guanfacine has also been used as an antihypertensive medication.  The cardiovascular outcomes included: Ischemic heart disease, cerebrovascular disease, hypertension, heart failure, arrhythmias, thromboembolic disease, and arterial disease.  The statistics of interest were adjusted odds rations comparing cases to controls.  The authors also did a brief literature review in both the introduction and discussion sections of the existing literature in this area and what can be described as mixed results.

Their main finding was that only two cardiovascular conditions – arterial disease and hypertension were significantly associated with stimulant medication use but not with atomoxetine or lisdexamfetamine use.  Risk also increased at a level of 1.5 DDD (defined daily doses) of stimulant medication.  Those specific doses except for guanfacine can be found at this link. 

The authors do a good job of interpreting the limitations of their data including the possibilities of under detection of the true rate of cardiovascular disease at baseline, the possibility of mediation nonadherence and underestimating the effects of medication exposure, and confounding by severity could be an issue through the effect for more severe ADHD on lifestyle factors important in the genesis of cardiovascular disease (CVD). Finally, since the study eliminated subjects with existing CVD – stimulant exposure was not measured at all in that population. The authors advise very cautious treatment and monitoring of those individuals.

All things considered, this was a good approach to studying the effects of ADHD medication exposure and the development of cardiovascular disease on a significant sample.  It was a convenience sample from a pre-existing registry.  The authors point out that some treatment groups were very small and advocated for a similar study with a larger N.   Just looking at the trends in their tables, there is clearly significant cardiovascular disease in both the test and control subjects.  The odds ratios for medication exposure were low when they were significant.  Few medical variables were controlled for (obesity, Type 2 diabetes mellitus, dyslipidemia, and sleep disorders) and of those 3 out of 4 are more common in patient with ADHD (3).  More subtle forms of effects from ADHD like whether there are affective changes (typically irritability and anger) leading to hypertension or a white coat effect are unknown currently.

That leads me back to the need for close monitoring for cardiovascular risk factors and conditions before any medication is considered. The group with pre-existing cardiovascular disease is at highest risk and they have not been studied. My speculation is that even using a large health plan database those numbers (patients with cardiovascular disease started on ADHD medication) will be small.  Any real world clinical scenario where this is being considered should be approached as cautiously as possible and monitored the same way.

Social Media Discovers Managed Care and Rages - Or Not?

I watched TMZ last night and they were fascinated about the homicide of Brian Thompson the CEO of United Healthcare in New York City the night before.  The hosts could not approach that topic directly so they brought on Taylor Lorenz who they described as a social media expert.  She made some posts about healthcare companies.  She claims that the “entire internet left and right” was united in celebrating the death of this CEO because “Somebody stood up to this barbaric, evil, cruel violent system.”  Her rational is that if you see a loved one die because an insurance company denied care it is natural to want to see that person dead and this is not advocating homicide. It is a justice fantasy.  She went on to say that United Healthcare has murdered tens of thousands of Americans by denying healthcare.  She sees this as a revolution and it is a problem that should be addressed without violence.  She suggests letter writing and possibly politicians and journalists getting a clue and seeking to correct this imbalance. 

I have been aware of United Healthcare for at least 30 years.  They are renowned in Minnesota for their initial emphasis on not funding psychiatric care and moving on from there.  Physicians like me have been railing against United Healthcare and other managed care companies for decades.  And nobody - and I mean nobody cares. No politicians, nobody in the media, and nobody in physician professional organizations.  There has been an occasional activist state Attorney General suing these companies into a temporary correction that they can easily wait out.   The American Medical Association just recently came out against prior authorization one of the main forms of managed care denial – just a few years ago.  It has been in place along with utilization review – the other main form of denial for at least 40 years.

These business practices have transformed the practice of medicine into a high productivity and low-quality enterprise where medical judgment is replaced by the judgment of middle managers with no medical training and company profit in mind. Physicians have been displaced in their roles in managing the treatment environment and now it is staffed by business people concerned only about the bottom line. If a company decides it is not going to cover a medication or a procedure or a hospitalization – the general message to the patient is “you are out of luck.”  I worked at the same hospital for 22 years and during that time we went from providing care to anyone who walked in the door to care based on businesses telling us what to do.  At one point to make things less contentious (and after we were bought out by a managed care company) – the external review was replaced by the same kind of decisions made by internal staff.  Some physicians became "managed care friendly" in order to move up the corporate ladder.

How did these organizations get so much power over healthcare?  A lot of it depended on lying to gullible politicians.  The original sales job was that physicians were just too expensive.  They order too many tests.  They were going to close down or buy out the expensive specialists and greatly expand primary care.  That primary care expansion would lead to more prevention and reduce the overall costs of medicine. But once these organizations were granted all the power they wanted, they began acquiring specialists and providing their own specialty care.  They also greatly expanded middle management to micromanage staff and basically tell them to work harder.  The result is a system that is much more expensive rather than more cost effective.  Shareholder profits and CEO salaries require a lot of denied care to fund.  This article about the company is an indication of the amount of money that we are discussing. We are talking about executives that are making tens of millions of dollars in an organization that rations health care.

Of course, people are angry about the situation of rationed health care. But it is more about how things are organized and all the associated politics. I think we can all agree that there do not seem to be many bright politicians out there and that low bar took an even more precipitous drop in the last election. Even managed care companies know more than to ration vaccines or give everyone hydroxychloroquine for COVID.

 Politicians have invented this system at every step of the way and made it impossible for the average citizen to get any satisfaction when their health care is denied. Federal and state governments both side with healthcare companies to support the denial of care and (incredibly) indemnify them from liability when their denials result in bad outcomes.  Death is just one of many bad outcomes. 

The press does not get it. I am tired of writing about it for physicians.  The only bright idea that group seems to have come up with is not contracting with these companies and either charging cash or asking the patient to seek their own insurance reimbursement after paying their bill. This obviously has limited application and doesn't work if the patient needs more resources like operating rooms or rehab facilities.  So - Ms. Lorenz’s solution of writing letters certainly will not work.

Some news services seemed to connect a policy reversal by Anthem Blue Cross/Blue Shield (ABCBS) to the homicide. Some of the original stories claimed that anesthesia time per procedure would be limited and the patient might need to pay the balance. Subsequent stories state that the insurance company planned to pay the time allotment indicated in the estimated relative value units (RVUs) for the surgery.  They claim their reversal was based on misinformation. RVUs are another form of rationing – paying only a set amount irrespective of the complexity of the case.  It is another way that psychiatric services were also rationed by reduced reimbursement.  In some cases, it leads clinics to stop seeing all the patients from a particular insurer based on low reimbursement to the physicians and providers.  Lorenz posted a caption of the ABBCBS story with the additional line:  ‘And people wonder why we want these execs dead.'     

This is the state of medicine in the US today. We have just had an election that puts the most rational parts of the fragmented healthcare system (the ACA or Obamacare, Medicare, and Medicaid) at risk.  The party in power espouses gun extremism and uses political tactics that direct violence and aggression toward specific individuals or groups. The party in power favors the top wage earners rather than production or knowledge workers. That includes large healthcare conglomerates that all function by rationing care and access to medications and procedures. And in that context, we have a social media expert claiming that we now have bipartisan rage against these health care companies who have murdered tens of thousands of people by denying their care.  I certainly know many people who have been harmed by the denial of care.  In some cases, I spent hours advocating for them and trying to get the care they needed but I was simply ignored.   

At this point, the crime is being analyzed like it is just another true crime TV show. Endless analysis about the perpetrator’s behavior and possible motivations.  It is all highly speculative but made as controversial as possible.  All the analyses I have seen so far seem way off the mark – but I am not going to add mine at this point.  I am more than a little suspect about all the social media rage. Is it real or just generated by a few provocative trolls?  Will it lead to a typical Congressional show hearing where members manufacture outrage and nothing changes. One thing is for sure – the current state of events is not a good sign.  It is a sign of just how corrupt, ignorant, and not self-correcting the American political system is - and just how much those politicians collude with businesses.

In the end, Americans end up paying top dollar for a healthcare system that may refuse to treat them, an airline system that may refuse to fly them, a financial system with excessive charges and minimal interest payments on savings, and a system for workers that disproportionately pays the people who do not do any of the brain or physical work.  Is it any wonder that 4 people in the US possess more wealth than 50% and that 50% are essentially left hoping for changes that never come.

As any reader of this blog can attest – I do not consider homicide as a solution to any problem.  The two main features of homicide that I consistently observe on this blog is homicide as a primitive value and a primitive solution.  It has no place in civil society.  In the anthropological literature homicide as a solution dates to prehistoric times when minor conflicts escalated from individuals to entire villages.  Modern man has not uniformly progressed very far as evidenced by every active war in the world right now and ever.  The shooting of Brian Thompson is no exception. Given everything, I have listed in the above post – it changes nothing.  It was a cowardly, immoral act, and unlawful act. I hope that the perpetrator is caught and punished.  I hope that the privacy of Brian Thompson’s family is respected.  

The Importance of Malaise...

About a year ago – a good friend of mine shared his observations about death and dying. 

“I have known 5 people who told me that they ‘felt the worst they had ever felt in their life’ and by that afternoon – they were dead.”  The “people” were all men.

He went on to describe what happened to our long-time mutual acquaintance and what he said on that fateful morning.  He described a man who went to work at a local factory despite his wife’s suggestion that he stay home and see a doctor. In every case the “worst I have ever felt in my life” predicted death in a few hours and did not deter these men from their usual daily routine.  Most of these men died of heart attacks.  They had atypical symptoms rather than chest pain – but my friend is not a physician and was not interested in the details only what they all said on the morning of their deaths.

The only time I felt that badly was when I sustained a ruptured and gangrenous appendix at age 18.  I had a very complicated course that included a Penrose drain being placed in my side to drain the remnants of the necrotic appendix. Even as I was healing, I felt horrible. I felt so badly that I did not care if I lived or died at that point. I was not depressed, nauseated, or in pain – just a very intense sick feeling.

That may be why I have had an interest in malaise as a syndrome.  I equate malaise with flu-like illnesses and that feeling you get from a severe case of the flu or flu-like viruses.  I had malaria once back in the 1970s and was very ill for several days.  That bout of illness was characterized by low energy, fever, and severe chills associated with the fever.  I can remember crawling across the floor of my house draped in a sleeping bag and into a tub of hot water just to warm up.  That was about 6 years after the appendicitis and the disease features were clearly different, but again not nausea, depression, or pain. 

Steadman’s medical dictionary defines malaise as:  A feeling of general discomfort or uneasiness, an out-of-sorts feeling, often the first indication of infection or other disease.  That definition captures the general experience but not the intensity.  I could tell that something was wrong in the early stages of appendicitis.  But in the space of 2 or 3 hours something was really wrong and the sick feeling was amplified a hundred-fold.  Are they both malaise?  Can malaise occur during a chronic condition – can you have acute and chronic malaise?  This semantic confusion may be why not many people seem interested in using the term. 

Interestingly there is a Malaise Inventory and it is in the psychiatric literature (1-3).  It was originally conceived by Michael Rutter as a measure of psychological well-being and the associated physical components.  It was adapted from the 195-item Cornell Medical Index Health Questionnaire.  The inventory itself consists of 24 self-competed questions and can be viewed here.  Many of the items (eg. Do you often feel miserable or depressed?) decrease item specificity.  Many of the items (eg. Do you often get worried about things?) are not specific for physical illnesses.  That may be why some authors found that psychological dimensions accounted for the more variance than physical ones.  It has generated very little research interest and is generally referenced once or twice a year in PubMed except for the year 2021 where there were 10 references.  In more recent studies it is used as a measure of psychological distress rather than malaise associated with a physical illness.

Why might it be important to have a more physically defined malaise? It could lead to earlier recognition of serious physical illnesses.  Based on what we currently know about pathophysiology – I would not be surprised if there were subtypes of malaise.  For example, the severe illnesses I have experienced were all most likely related to inflammatory signaling and the well documented effects of some of those molecules like cytokines. On the other hand, hyperadrenergic states associated with acute cardiovascular diseases could produce a different type of illness feeling.  We are generally limited by knowing the possible presentations (typical and atypical) to not miss a serious problem without reference to any non-specific illness feeling.  It may also allow for treatment of those associated symptoms. One of the striking features of the modern approach to appendicitis is rapid symptomatic treatment or pain and nausea. Are there better ways to treat acute infectious inflammatory conditions than NSAIDs and acetaminophen?  Are there better ways to treat chronic malaise?

My proposed analysis of malaise does not replace the need for common sense and recognizing the dangers of denial.  I am fully aware of the difficulty getting timely emergency care in the US health care system unless you need a trauma surgeon or interventional cardiologist.  But – if you are experiencing the “worst I have ever felt in my life” feeling you owe it to yourself and your family to get it checked out as soon as possible.  EMTs are called for a lot less.  I have talked to too many people who in retrospect would have called the EMTs instead of driving themselves to the hospital while they were having a heart attack.

Science and Politics…..With A Lesson from Psychiatry

 

I started reading this week’s edition of Science and was surprised to find several editorials about the relationship between science and politics. In addition to the editorials, news items like “Will Trump upend public health?” and “Trump picks lawyer for EPA.” Were no less alarming.

Marcia McNutt, President of the National Academy of Sciences wrote the first essay (3).  She correctly discusses science as a rational neutral process that by its very nature is apolitical.  She describes the peril of citizens ignoring scientific reality by quoting a 26% increased mortality rate in areas of the US where political leaders dismissed the importance of the COVID-19 vaccine.  She makes the point that science must define the body of information that policy should be based on - but it should not actually dictate policy.  She advocates for a role of listening to the affected people and fighting the disinformation that affects them.  Unfortunately, the process of active listening will not do anything toward fighting misinformation – especially when things get to the wide dissemination and meme stage. 

H. Holden Thorp, Editor-in-Chief of Science journals wrote the second essay (4) and it was more specific to the current political situation.  After commenting on the win for Trump he provides the following qualifier:

“Although his success stems partly from a willingness to tap into xenophobia, racism, transphobia, nationalism, and disregard for the truth, his message resonates with a large part of the American populace who feel alienated from America’s governmental, social, and economic institutions.”

The first clause in this sentence is accurate – but there are problems with the second.  Are xenophobia, racism, transphobia, nationalism, and dishonesty really symptoms of an underlying problem or do they represent the real problem of an opportunistic politician successfully scapegoating a portion of the population to gain the support of the electorate with these biases?  That has immediate relevance for the author’s proposed solutions of decreasing scientific misconduct to enhance public trust.  He points out that an animated defense on X/Twitter by scientists was not successful (how could it be based on the platform’s structure, biases and conflicts of interest?). He ends by correctly predicting that the attacks on science and scientists will go on unabated into the future and would like to see a response by the scientific community that makes them less successful.

The essay by Jaffrey Mervis (2) highlights concerns that research advocates have for the Trump agenda that is described at one point as defunding research to reduce taxes.  Any analysis of the tax plan shows that the savings are disproportionately awarded to the top 1% of wage earners.  A research physicist points out that there is no good news for science in the Trump agenda and that also translates to no good news to the tech industry that depends on government funded research for innovation.  Three areas from the Biden administration that may suffer are the Chips and Science Act, climate change, and research collaboration with China. 

The essay by Jocelyn Kaiser (1) focuses on the possible impact on the National Institutes of Health (NIH).  In this essay there is clear focus on Robert F. Kennedy, Jr. as a danger to the NIH and health related basic science research.  That danger on the one hand describes him with the euphemism “vaccine skeptic” and on the other quotes former NIH Director Harold Varmus as saying: ”enormous risks especially if [Trump] placed someone as unhinged as [Kennedy] into a position of responsibility.”  There is a lot of room between skeptic and unhinged.  Trying to present an even-handed description in this case is a clear error when responding to RFK’s rhetoric. It is not a stretch to say that his rhetoric may replace science as the guiding principle behind the NIH.  That is a problem regarding the role of science advising policy makers and a boundary problem on the part of rhetoricians.  Simply put – if you are an administrator with no science background and you are making science up – stay in your lane.

Another clear example of potential problems with a Republican Congress is still based on the COVID-19 pandemic and insistence that the bat coronavirus research was the source of the pandemic virus.  This has reached meme status in the MAGA community fueled by rhetoric from both Trump and members of Congress who have directly attacked NIH scientists.  In some cases those verbal attacks have resulted in threats of violence to those same scientists. All of that happening even though the origins of SARS-CoV-2 are not settled science - but most recent reports suggest origins in the wild like practically all pandemic viruses. Some politicians want to reform the NIH and that is typically a code word for changing an institution to something more like the one they want.  In the case of the Trump administration that can include banning fetal tissue research and I would expect other issues related to women’s reproductive health that the religious right objects to.

The final essay by Rachel Vogel (5) is focused primarily on the implications of Trump’s threat to leave the World Health Organization (WHO). The author reminds us that Trump started this process in July 2020 based on the false claim that “WHO had helped China cover up the spread of the virus in the early days of the pandemic.”  The Biden administration came in and stopped that process.  WHO member states are bracing for a second withdrawal or a reduction in funding to key programs that many think would be catastrophic.  Cuts could also be made to the US Agency for International Development (USAID) that administers many of these programs and other agencies funded to research and treat tuberculosis, malaria, and AIDS.  Political and religious ideology may also be a factor.  A program for AIDS relief started by George W. Bush is a possible target for indirect support of abortions and the use of language that right wing religious groups consider offensive including “transgender people” and “sex workers”.  It is likely that a “gag rule” on the dissemination of abortion information will be reinstated and the penalty will be withdrawal of funding.  Like aspects of the other essays, the author is hopeful that there will be ways to compensate for the Trump worst case scenario. Reform of the NIH has been talked about in the past.  Europe and other countries could compensate for the lack of US support.  Competitive funding sources like the BRICS group (Brazil, Russia, India, China, and South Africa) could also come to the forefront.  The amount of funding available from BRICS and what those countries would require in return is speculation at this point.    

The 5 essays highlight real problems and given Trump’s current nominations for the Director of HHS and NIH probably minimize them.  Suggested solutions to the problem seem to be the time-honored stay out of politics, present the data, and take the high road.  This is really an inadequate plan.  How do I know this?  The valuable lesson is that this is what psychiatry has done for decades.  Ever since Thomas Szasz began his repetitive rhetoric that there was no such thing as mental illness, or that psychiatric diagnoses were like drapetomania (later modified to drapetomania was somehow a psychiatric diagnosis) we have had to tolerate nonsensical criticism while major physician and psychiatric groups were silent.  The many leaders in the field who did respond and had excellent responses were eventually ignored as the neo-Szaszians continue to repeat this nonsense decades later.  An experiment by Rosenhan that was exposed as fraudulent continues to serve as an anchor point for antipsychiatrists – even though what happened clearly did not impact the field (deinstitutionalization had already started and the neo-Kraepelinians were already at work on reliable and valid diagnostic criteria).  The result of this rhetoric is significant hangover on the field. It is difficult to make a direct connection but common sense dictates that psychiatric resources probably takes a hit from all the repetitive negative rhetoric. That is the risk to all of medicine, public health, and scientific research with the current MAGA rhetoric.

Science typically considers itself above rhetoric and politics at least until the competition for grant funding heats up.  The editorials all fail to comment on this.  Instead, they suggest that leading by example, being available for consultation, and generally taking the higher ground will somehow correct corrosive politics.  That is both a naïve and losing strategy.  We currently have a party that has lied and misinformed the public repeatedly and at record levels.  It is supported by a large mainstream media organization with the same goals providing a constant diet of misinformation. It is funded by billionaires. The effects of all those dynamics are easily observed in attitudes toward real science and scientists.  Experts on autocracy and authoritarianism point out that the effect of constant lies on any group of citizens is that eventually they don’t believe anything – even if it happens to be the truth.  A standard authoritarian tactic is to attack expertise and pretend that it does not exist.   

At no recent point in history have legitimate scientists, physicians, and public health officials been threatened with violence by people who have no clear idea of what they do.  In many cases these professionals have been responsible for saving thousands of lives. That situation should be intolerable to any scientist or modern citizen who can evaluate the effects of science.  Furthermore, it should not be supported at any level by the government, but it currently is.  The same party that that supports lies also supports threats and violence at various levels up to an including an attempt to overthrow the US government. With the current election there is the expectation that attempt will be whitewashed as a protest further eroding the rule of law.

The curious aspect of this process is that it is right out there in the open. The repetitive lies are picked up by social media.  Proxies of that ideology begin to amplify them to the point that they become memes rapidly assimilated by true believers in the same ideology.  At that point they become part of that culture and resistant to change from rational arguments and additional information. There is no evidence that I am aware of that change is possible at that point and the most recent Presidential election is solid evidence.     

There is a semi rational basis to politics at best.  The current election illustrates this at many levels.  Major questions of character, intellect, and policy were ignored. The fact checking mode of the fourth estate was minimized.  Some media outlets were mere propaganda arms and provided no information for voters to make an informed decision. 

The only rational course is to continuously counter the repetitive propaganda being put out in social media.  There is no comprehensive strategy for doing this but it must be done.  It will take more than a few editors from Science journals.  A starting point may be a coalition of editors of science and medical journals with their own website dedicated to refuting misinformation and posting the real science. The time has come to stand up for what is science and what it not and protect people under attack for doing the right thing.

The Most Important Thing I Learned in the 8th grade….

 

I grew up in the northernmost regions of Wisconsin on the shore of Lake Superior. I also grew up a relatively long time ago. There were no wealthy people around – you were either a working-class family with a regular pay check or a working-class family with an irregular paycheck. It all depended on the work.  My father was a railroad fireman (he shoveled coal in steam engines) and later an engineer on diesel locomotives.  Even though he was in his forties work was very irregular due to the seniority system used by railroads.  The oldest people got their selection of jobs and there were more people than jobs. Many people at the top refused to retire creating a lot of anger and controversy by younger people wanting to work more hours.

The entire population of my home town was from European ancestry – everyone was white. Irish and Scandinavian derived families clustered on the west side of town and eastern European, German and Polish families on the east side of town.  We lived on the east side about 7 blocks from the lake.  

The town was located between two reservations inhabited by the Red Cliff and Bad River Tribes of the Lake Superior Chippewa. It was rare to encounter anyone of Native American ancestry unless you played sports and competed against some of those teams or until you were in middle school or high school. I used to fish on the Bad River Reservation with my grandfather and we got to known some of the men who ran a local boat landing.

Racism was overt and it was everywhere.  That may sound odd given my description of the place, but it would not take much to set people off.  An image on television like Muhammad Ali talking in his usual provocative manner or Willy Mays showboating in center field was all that it took. Racial epithets followed at a rate and intensity that was quite unbelievable.  There were a few cooler heads.  My grandmother was one.  All that she could do was to insist that people not talk like that in her presence.  As a boy – it was a mystery to me that the rest room facilities on trains were segregated – even though we were practically in Canada and there were no black people around.  I asked my father why the porter had to have a separate bathroom and he could not give me an answer.  At the time I had never seen a porter.    

The time frame of my youth coincided with the American Civil Rights Movement (1954-1968) but there was no discussion of it in schools, churches, or the public discourse.  The only place where it came up at all was in my 8^th grade biology course.   On a day back in 1965 – I learned the best lesson I ever learned in high school and possibly in my life.

I was a definite nerd back then and extremely interested in science – especially biology.  It was the only class that seemed to be interesting.  That was probably fueled by being a neurotic kid and always wondering if I had an undiagnosed disease or not.  My imagined symptoms at the time seemed limitless and I would find myself in the library researching rabies and various cancers primarily.  It seemed that cancer was always a dinner table topic for my parents.  A relative with exploratory surgery and the ultimate ending: “They just sewed him back up – there was nothing more they could do.”  There was not a lot available to an 8^th grader with those interests so I ended up picking up a lot of biology on the side. That could be useful or not depending on who the teacher was – so I kept most of it to myself.

I can still recall the excitement of learning that our biology course had been changed to Modern Biology and there was a new textbook (1). Our teacher told us the course would be more relevant and it could also form the basis for a college trajectory.  All I can remember about it today is frog dissections, the genetics of taste testing and tongue rolling, and the idea that race was a social construct that had nothing to do with biology.

That’s right – the social construct bomb was dropped in the middle of the Great White North in 1965 and it did not make a sound. There was no emphasis about it.  There were no lessons seeking to connect it to the culture at the time and the Civil Rights Movement.  There was no controversy at school board meetings. It was right there in the book.  A biological definition of races and a description that the isolated groups that were called races would probably intermix at some point and the artificial, color-based designations would just disappear.  We would all be one big happy Homo sapiens family. That information was as rational as it was profound when I read it the first time and witnessed how the idea was repeatedly violated over the next 50 years.  I had seen it violated so many times I went back and found the original biology text that I read in the 8^th grade.         

Some of the key quotes from that text are on the following graphic.  The basic idea is that the species originated and subpopulations migrated over thousands of years and were geographically isolated. During that isolation mutations occurred in those populations that led to some alterations in physical appearance but the genome wide similarities were still much greater than any between population differences. One standard species definition is the ability to interbreed between populations and that was sustained.  Even though populations were named by different physical characteristics they were biologically identical. In the modern era, the longstanding physical barriers to population mixing are no longer present and we should expect a more homogeneous population over time.

Flash forward to 2024.  I just read a paper (2) that should be read by everyone and combined with my personal experience is the impetus for this post. The additional impetus is the recent election in the US and a political cultural movements that are overtly racist, anti-racist, and anti-anti-racist. There are some common interests.  As a clear example, the overtly racist and anti-anti-racist movements coalesce around the central idea that the white race will be “replaced” by non-white races and this will result in significant loss of political advantage. That theory is called the Great Replacement Theory and it plays out at several levels not the least of which is the claim that one party seeks to use it to their advantage to get more voters and they will do this by illegal immigration. Never mind the fact that non-citizens cannot vote.  And never mind the fact that the current political landscape is a small blip in geological time. 

The paper is written by two evolutionary and theoretical biologists.  Expectedly it contains an abundance of modern theory about human genetics, evolution, and most importantly modes of transmission between individuals in populations. The most interesting focus for biologists and physicians is that there are ways to transmit behaviors between generations that are outside genetic transmission and that there are potential interactions between these modes and individual genetics.  The authors use an example of dairy farming and the persistence of lactase alleles.  Dairy farming can select for those alleles in the population but cultural adaption like the use of milk fermentation can also be successful in the absence of lactase persistence.  The main drivers of non-genetic inheritance are depicted in the graphic at the top of this post from the authors’ paper. 

In the body of the paper, they discuss cultural evolution (CE) and gene culture coevolution (GCC) models.  The lactase allele in the context of dairy farming is an example of GCC.  They discuss common errors made in suggesting that race is biologically based and introduce how cultural factors explain some of the differences attributed to genetics.  Intellectual differences are cited as one early example that was attributed to genetics – but modern genetic studies and combining cultural factors shows that there are no clear genetic differences between comparison populations and that all of the differences in educational achievement can be attributed to cultural factors like cultural role models, parental expectations, resources, social roles, and environmental niche.  Negative factors like racial discrimination and adverse life experiences can also play a role.  This paper is a reminder to carefully look for other sources of variance in large in genome wide association studies (GWAS) and whether cultural factors were studied.  My speculation is that the commonest cultural factor in play these days is childhood trauma because the Adverse Childhood Experiences (ACE) checklist is available and considered a measure. This paper would suggest that is only part of the story.      

So here it is nearly 60 years after I read that race has no biological basis and that it is a social construct - it is still being used to divide citizens, suppress the vote, ration resources, stereotype people, direct violence at people, and actively discriminate against them.  I don’t know if reading this paper will be helpful at all so I provided the slides comparing my 8^th grade biology text and a current state of the art paper in abbreviated form.

I did not touch on the rhetoric involved and that is long, detailed, and discussed in other places on this blog.  Very briefly – philosophers and other rhetoricians have taken an anti-science stand in the past because they believed that science was given too much power.  That came about as philosophical musings gave way to more predictable scientific explanations. The problem is that science is an evolving process rather than a book of clearcut answers with some areas less evolved than others.  Eugenics and even more recent claims that race and associated cultural characteristics and endpoints are genetically based could be considered part of that process.  But many of these arguments still persist and like other areas of science have been politicized.  The authors here present all the reasons those arguments about race as a biological property are wrong.      

It was known in 1963 and it’s even more well known today.

Supplementary 1:  In terms of cultural factors and educational attainment I was reminded of one from my background - the Medical College Admissions Test (MCAT).  Back when I took it there was a general knowledge section that was supposed to show that the applicant had a knowledge base outside of science.  It was heavily weighted to the arts and humanities.   It was eventually eliminated because it was shown to favor students in large cities where there was access to art galleries and museums.  The closest museum was 200 miles away.  My family rarely left town.  When they did it was usually to pick up my father from a train station about 30 miles away.  

Supplementary 2:  It is interesting to consider the political rhetoric of the last election as it applies to the concept of race as a social construct.  It was common to see minority groups that in some cases were extremely small being scapegoated for political purposes.  Some of it had to do with long standing racism and some of it had to do with cultural factors.  The whole point of this blog post is how can any of that be acceptable if we are all members of the same race with trivial differences in appearance and behavior?
