DR. C’S JOURNAL: CAUSES & SYMTPOMS OF INSOMNIA

Sleep has many functions, among which are clearing the body of toxins and consolidating memory. The exact amount we need is determined by age, and genetics among another things. From what I’ve read, eight hours is required, plus or minus an hour.

That being said, there are a few  among us who are super sleepers. Going back in history this probably included Mozart and Thomas Edison: They could live healthy, productive lives with as few as three or four hours of sleep. Genetic mutations, including changes to the Orexin Gene receptor account for true super-sleepers.

Familial fatal insomnia is a genetic disease operating through prion proteins, and does not illuminate the problem of insomnia. In most people  there are two major forces which determine the onset of sleep, the circadian rhythm, and sleep pressure.

The TIMING of the sleep varies from morning larks to night owls. These shifts in the circadian rhythm is also genetic, involving many genes, including PER and CRY. Diurnal rhythm can apparently be changed, But with difficulty.

The sleep pressure is caused by the gradual daily accumulation of adenosine in the system, apparently resulting from the stripping away of the phosphate groups from the energy currency, ATP.  This can be assuaged by caffeine containing drinks, such as tea or coffee. Caffeine temporally blocks the effect of adenosine, but when it wears off, you usually go right back to your fatigue state.

INSOMNIA occurs when you do not get as much sleep as you need, and are tired in the daytime. This is a major problem for a lot of people.

Insomnia has many causes. Stress will cause an increase in Cortisone in the bloodstream which interferes with sleep. Caffeinated drinks nicotine and other stimulants can cause you to have difficulty falling asleep, and alcohol will help you fall asleep but will often result in awakening in the middle of the night when the alcohol is metabolized.

Depression, Parkinson’s, chronic pain, gastroesophageal reflux and any other medical conditions can interfere with sleep. Sleep apnea, often associated with overweight and heavy snoring, is a special problem that sometimes needs the help of a sleep specialist.

Some poor habits such as reading in bed, doing work in bed, eating at bedtime, and heavy exercise just before bed can also be a problem.
A regular routine of Preparing for sleep, such as brushing and flossing and taking a warm shower are also helpful; you can get more details by looking up “sleep hygiene”.

A lot of people take a nap, but this can cause some difficulty in going to sleep. Among things you can do to prevent insomnia include living an active life, making your bedroom comfortable for sleep, and using your bedroom ONLY for sex and sleep.

VIEWS: IS U.S. HEALTHCARE SYSTEM BROKEN? (HARVARD)

Here’s a question that’s been on my mind and perhaps yours: Is the US healthcare system expensive, complicated, dysfunctional, or broken? The simple answer is yes to all.

Below are 10 of the most convincing arguments I’ve heard that our system needs a major overhaul. And that’s just the tip of the iceberg. Remember, an entire industry has evolved in the US just to help people navigate the maddeningly complex task of choosing a health insurance plan.

The cost is enormous

  • High cost, not highest quality. Despite spending far more on healthcare than other high-income nations, the US scores poorly on many key health measures, including life expectancy, preventable hospital admissions, suicide, and maternal mortality. And for all that expense, satisfaction with the current healthcare system is relatively low in the US.
  • Financial burden. High costs combined with high numbers of underinsured or uninsured means many people risk bankruptcy if they develop a serious illness. Prices vary widely, and it’s nearly impossible to compare the quality or cost of your healthcare options — or even to know how big a bill to expect. And even when you ask lots of questions ahead of time and stick with recommended doctors in your health insurance network, you may still wind up getting a surprise bill. My neighbor did after knee surgery: even though the hospital and his surgeon were in his insurance network, the anesthesiologist was not.

Access is uneven

  • Health insurance tied to employment. During World War II, healthcare was offered as a way to attract workers since employers had few other options. Few people had private insurance then, but now a layoff can jeopardize your access to healthcare.
  • Healthcare disparities. The current US healthcare system has a cruel tendency to delay or deny high-quality care to those who are most in need of it but can least afford its high cost. This contributes to avoidable healthcare disparities for people of color and other disadvantaged groups.
  • Health insurers may discourage care to hold down costs. Many health insurance companies restrict expensive medications, tests, and other services by declining coverage until forms are filled out to justify the service to the insurer. True, this can prevent unnecessary expense to the healthcare system — and to the insurance company. Yet it also discourages care deemed appropriate by your physician.

Dr. C Commentary:

Please refer to the DWWR Posting on “concierge doctors” for my rant on the current healthcare system, which I will not repeat.

The truth is more nuanced. All countries are having trouble of one sort or another with their healthcare systems. This is due to the inherent expense of today’s top flight medicine. The very best care requires costly high technology and drugs that are intrinsically hard to produce. And you have to know where to look. I am very thankful for my medical degree, and that I have kept up with current advances.

You would probably need a Government entirely of physicians to develop the willpower to do something for health, which always starts with PREVENTATIVE MEDICINE, A hard sell, given that you must spend money and effort to block something which will probably, but may not always, occur.

There is low hanging fruit. Why are sugary drinks not heavily taxed, since they produce obesity which causes a lot of costly medical disorders, such as diabetes, inflammatory diseases, and cancer, but not everybody all the time?

Why is efficiency of telehealth not more widely embraced, but stymied by moneymaking lobbiests and lawyer powered difficulties, in addition to Patient’s and doctor’s old habits?

And then there are the jealously guarded  American freedoms to do stupid things, such as avoid vaccines and masks, even in a prodigiously expensive and dangerous Covid  epidemic.

Given human nature, a complete solution would seem to be impossible, and we should content ourselves with minor victories wherever they can be attained.

Embrace sleep, diet, and exercise, and KEEP HEALTHY.

DR. C’S JOURNAL: BENEFITS OF PARATHYROID HORMONE

Hormones, Vitamins, and minerals all have extensive interactions in the give-and-take of the bodies’ ballet of homeostasis. No where is this more clear-cut than the interplay of parathyroid hormone, vitamin D, and calcium.

Although it has many other actions in the body, calcium is best known as the prime component of our bones. It is essential for making them healthy and strong. The bones act as a storehouse or vault for the bodies calcium. The parathyroid hormone is the key that unlocks the vault to release the calcium so it can perform its many other roles in the body. An elevation of the calcium in the blood stream shuts down the parathyroid Glands.

Parathyroid hormone also acts to instruct the body to absorb more vitamin D, just as the vitamin D causes the intestinal tract to absorb more calcium. The parathyroid glands are in the upper poles of the thyroid which as we mentioned before sits astride the windpipe.
Sometimes the parathyroid gland develops an adenoma which causes too much secretion of parathyroid hormone.

This results in an excess of calcium in the body and a variety of symptoms, such as joint pain muscle weakness, fatigue, nausea and vomiting. One of the technicians in my medical practice developed hyperparathyroidism. It was detected by a metabolic panel, which showed an elevation of serum calcium.

This discovery, early in my practice, made me a big fan of metabolic panels when patients have general symptoms. Her condition, a parathyroid adenoma, was cured by surgery. Conversely, surgery for an overactive thyroid can sometimes accidentally remove the parathyroid glands if the surgeon isn’t careful. The parathyroid glands are tiny, but they perform a huge function.

Covid-19: ‘mRNA Vaccine – How It Works’ (Video)

Its decision time for Covid vaccines, especially for 88-year olds. The choice is among live-attenuated vaccines, whole virus vaccines, Split virus vaccines, and RNA vaccines, and I prefer the latter because of its simplicity. It delivers just the mRNA coding for covid spike protein, without the risk of a live vaccine, and the extra substances in whole and split- virus vaccines.

mRNA utilization for a vaccine is not new technology. The idea has been floating around for decades in cancer immunotherapy research. The sophisticated understanding of the technology is reassuring. It has a high efficacy, approaching 95%. Between the Pfizer and Moderna mRNA vaccines, I prefer the Moderna vaccine, because the Company was already working on a mRNA platform for MERS, a Covid-family virus, and has developed their own lipid capsule as a vector.

The Moderna vaccine does not require the extremely low storage temperatures like the Pfizer product. With all production located within the company, Moderna will be ready to go if a new strain nullifies covid 19 vaccines, or if another virus spreads worldwide. Timing is important. The mRNA vaccine requires 2 doses. I intend to take the first Moderna dose when I can get it locally without standing in line.

Since I intend to continue Masking and Distancing until the cases in my community are low, I will probably delay the second dose until summer, to increase my likelihood of effective antibody levels this coming fall and winter. Also, there will be more information by that time on the Vaccine’s effectiveness and duration in the Elderly.

The pathogenicity of the English, or any other newly mutant strain will be hopefully known by Summer. The rapid Covid test using sputum, and outpatient treatment with monoclonal and convalescent antibodies for early cases will then be available. I want a treatment plan in case I get infected. This is a treacherous, nasty infection.

Dr. C’s Journal: ‘Mutation’

Mutation is engrained in the very nature of life. Even if there were no X-rays, free radicals or toxic chemicals, mutation still would take place because of errors in the replication of DNA that occasionally escapes the proofreading mechanisms of meiosis and mitosis.

The majority of germline mutations produce LOSS OF FUNCTION, and are weeded out by evolution. In vertebrates, mutation is vital in producing the random changes in the DNA of germ cells of the ovaries and testes. If the mutation is beneficial, involving a GAIN OF FUNCTION, environmental selection acts to preserve the change, producing the diversity of organisms in the world, each exploiting a different environmental niche.

It is the rare species so versatile, like the shark, that can remain almost the same over eons without dying out. In the teeming unicellular world, mutation in the genome is similarly useful in allowing for variations which often prove useful for survival. The mutations thrive if the proper environment presents itself. For instance, antibiotic resistance may be encoded in a few members of a bacterial species, which become the dominant members in an infected patient on antibiotic treatment, and crowd out family members without the mutation.

In Viruses, RNA is often the Memory nucleotide. RNA is less stable than DNA. The resulting instability allows more mutations, and sometimes greater success. An example is the English Covid variant in the spike protein which leads to greater contagion. Hopefully, the spike protein change will not be so successful as to interfere with the effectiveness of vaccine-produced protective antibodies.

The Mutations we have been discussing refer to GERMLINE mutations, which occur in the gonads. In higher animals, germline mutations affect the offspring, which then carry the mutation. A GAIN OF FUNCTION mutation may confer greater adaptability and survivability, and perhaps may lead even to a different species, if the troop number is small and the environment demanding. Non-germ SOMATIC cell mutation may lead to undesirable effects like cancer, which is another discussion.

‘INFECTIONS’: HOW WE EXPERIENCE INTERACTIONS WITH MICROORGANISMS

The RNA molecule is central to life. It is the information molecule of the Pandemic SARS CoV 2 virus, whose Messenger RNA specifying Spike proteins is the basis of 2 recently-released vaccines.

“RNA Life” is the leading theory for the Origin of Life itself, more than 3 Billion years ago. DNA evolved as the blueprint information molecule in cellular life, but the ubiquitous RNA may well have become the first viruses.

The stage was set for the ongoing battle of life: Parasite vs. Host, Pathogen vs. Target, but recent research reveals a much more nuanced picture. Viruses and bacteria can be BENEFICIAL as well as deleterious. We now speak of the MICROBIOME, usually referring to our host of resident BACTERIA, and the VIROME referring to all of our indwelling VIRUSES.

INFECTION is how we experience our interaction with microorganisms, their benefits unseen. Bacteria, viruses and parasites have always been with us, increasing in impact as Paleolithic man crowded into agricultural settlements.

Enlarging cities became more dense, favoring spread of infection and PLAGUES. The Bacterium, Yersinia Pestis,emerged in Roman times,
causing the Justinian plague, and resurfaced in the 14th C. as the Black Death. Viral Plagues, including Smallpox, were devastating during European adventures into the New World.

Malaria, a one-cell Eukaryotic Parasite, may be the greatest killer of all time. Modern Sanitation and improving medication have lately pushed bacterial infections into the background.

Viral infections such as Influenza and most recently Covid have become the Modern face of infection. Many Viruses reduce Immunity, however, paving the way for bacteria to invade: Haemophilus influenzae, a bacterium, may have caused much of the mortality of the 1817-1918
Flu epidemic.

IV drug usage has facilitated the spreading of the viruses causing Hepatitis and AIDS. The immune-compromising nature of the latter has reinvigorated TB and Syphilis, both bacterial infections. Only a few years ago, bacterial infection was thought to be conquered by antibiotics, and viral infection contained by Vaccines.

Microorganisms are constantly evolving, however, and often share their resistance factors. Infection is no more a thing of the past than War. The Battle continues.

DR. C’S JOURNAL: VACCINES, ADAPTIVE & INNATE IMMUNE SYSTEM AND HERD IMMUNITY

The adaptive immune system is the “big gun”, later evolved, big brother of the innate immune system. The innate immune system acts a little like prejudice does in society. There is INSTANT RECOGNITION of a salient characteristic of many common disease-producing organisms, that are not present in the person being infected.

For instance, ENDOTOXIN is a lipopolysaccharide present in many bacteria, and is immediately recognized by Toll-like Receptors (TLR-4) on dendritic cells and macrophages. This triggers the Natural Killer (NK) cells to destroy the invader. The problem is that the innate immune system is indiscriminate, reacting against whole classes of molecules like a shotgun, and may produce unwanted damage. It also fails to recognize many genuine threats.

The ADAPTIVE immune system is more complex, discriminant, and SPECIFIC, but is SLOWER to gear up, and takes several days to be effective. Once engaged, however, it has a MEMORY for the infection that is SPECIFIC to the organism involved. This memory makes a SECOND EXPOSURE response much more rapid and comprehensive, AMPLIFIED as it is BY ANTIBODIES.

This first experience can be PROPHYLACTICALLY accomplished by VACCINES, so that the second, real exposure generates a RAPID PROTECTIVE RESPONSE. ATTENUATED vaccines are weakened, but LIVING ORGANISMS, and usually provide a more DURABLE immunity, but because they are living, they are more worrisome.

SPLIT-PRODUCT Vaccines are safer, but expose the immune system to a narrower range of pathogen markers, and may therefore be less Protective.. The FDA is very dedicated to SAFETY. Like all Bureaucracies, it is relatively independent of Political pressure, of which I am increasingly appreciative.

When the COVID-19 VACCINE, for example, is released to the general public, it WILL BE SAFE. The vaccine-deniers are mis-informed people who should not, in my opinion, be allowed to interfere with the HERD IMMUNITY that comes with having a supermajority of the population vaccinated.
