Safety & Efficacy of Lowering Lipids in the Elderly

I am bombarded regularly by older patients, their adult children and various elements of the media with complaints that elderly are taking too many medicines. Poly pharmacy is the word they use and the first prescription medications they want eliminated are their cholesterol lowering drugs – either a statin (Lipitor, Zocor, Pravachol, Crestor , Livalo or their generic form), Zetia ( Eztimebe) or the newer injectable PCSK9 inhibitors Repatha and Praluent. Is there an age that we should stop these medications? Is there benefit in the elderly to continue taking them? Should we start these medications in the elderly if we discover they have high cholesterol and vascular disease?

A recent study was published in the prestigious Lancet medical journal. The authors looked at 29 trials with 244,090 patients. From this pool there were 21,492 patients who were at least 75 years old. Half of them were on oral statin drugs and the others were on Eztimebe or PCSK9 inhibitors. They were followed from 2 – 6 years.

The results showed that for every reduction of LDL cholesterol of 1mmol/L there was a 26% reduction of in major adverse vascular events. These numbers were similar to those in younger patients. The data also pointed out that these patients had a significant reduction in cardiovascular deaths, myocardial infarction (heart attacks), strokes and the need for heart surgical revascularizations. It was extremely clear that if you are on a cholesterol lowering drug you should stay on that medication despite your age!

A study in JAMA internal medicine, authored by LC Yourman, answered the question of whether you are too old to start on a cholesterol lowering drug. They found that it took 2.5 years before the cholesterol lowering medicine reduced your risk of a major cardiovascular event. Their conclusion was that if you are 70 or older, and your lifespan appears to be greater than 2.5 years, you should start the medicine.

Caffeine Before Exercise Helps You Burn Fat

Researchers at the University of Granada have published a research article in the Journal of the International Society of Sports Nutrition showing that drinking a caffeinated beverage 30-minutes before exercising in the afternoon is the best way to burn fat. Morning exercise with caffeine, or without, was less productive at burning fat than afternoon exercise. Fifteen men, with an average age 32, each completed an aerobic exercise test four times with seven days in between testing. On the days tested, they were given either a caffeine dose equivalent to a strong cup of coffee or a placebo. They then rested for 30-minutes and then completed the aerobic exercise. Their meals were standardized on test days. Researchers measured the participants for fat oxidation, maximum oxygen uptake and exercise intensity.

Caffeine increased fat oxidation by 10.7 % in the morning and 29% in the afternoon. Caffeine increased exercise intensity by 11% in the morning and 13% in the afternoon. Maximum oxygen uptake was higher in the afternoon.

Recent literature has shown the benefit of tea in lowering systolic blood pressure. I think I might try a stiff cup of tea 30-minutes before my after-work exercise regimens. Come to think of it, Ii will try some coffee prior to my weekend morning workouts as well.

The Pandemic, Snail Mail & Credit Reporting

Not a day goes by that I do not receive an unsolicited email offer to run my credit report for free.  It never occurred to me that while the pandemic was raging, and millions of people were out of work without a true source of income, business as usual was occurring at the three major credit reporting firms.   I have been extremely fortunate in that my wife and I have been able to pay our bills on time.

The only negative issues we have run into is the dreadfully slow journey first-class mail takes today.  Bills and invoices for services rendered arrive late routinely if they arrive at all. I mail my payments when I receive a bill or invoice well in advance of the due dates.  Sometimes they arrive. Sometimes they disappear off the face of the earth. They all have my return address on them, but none have been returned. I mail them from the local post office these days putting on a mask and gloves and dropping them in the stamped mail slot inside the post office. 

Last month I ran out of first-class stamps, so I went to the nearby Post Office on Banyan Road and bought stamps directly from a postal employee inside because the automated machine was out of order. I stamped my three envelopes and handed them back to the postal worker behind the counter.  Those were payments to FPL, Florida Public Utilities (gas company) and to my homeowner’s insurer Tower Hill.  Those payments never arrived. Those checks never cleared.  USPS is so slow that several companies I purchase from refer to US mail as “snail mail.”

My children tell me to “… pay your bills online by setting up an automatic deduction from your bank account”.  This comes a few days after another major cyberattack and hack – this time to Facebook.  I used the email address and app Facebook provided to see if my credentials were part of the stolen data and yes, they were.  I subscribe to LifeLock for help in protecting my identity, so I know my data flows on the “Dark Web”. Last month someone tried to use that stolen data to obtain unemployment insurance in the state of Illinois.  I squashed that quickly.

Credit scores are used today to evaluate job applicants. They are used to determine if you qualify for all forms of insurance, and how much you need to pay, including life insurance, auto insurance, homeowner’s insurance and possibly health insurance.  I can see checking a credit report if you are trying to buy something and are trying to obtain financing or a loan to pay for it. Even in that arena, this summer I leased a car from Acura.  I have leased a car from Acura using their finance company for twenty-five years now.  Did they need to run a credit report to determine if I pay my auto lease?

I think there should be a moratorium on credit reporting just like there is a moratorium on home evictions.  It should start in May 2021 and run until at least April 15, 2022.  Millions of people will be trying to get back on their feet as the vaccines take hold and people return to the workforce. They deserve a chance to rebuild their lives and their credit rating without the discrimination against them caused by the pandemic’s effects on the economy.

Put on a Mask and Just Stay Home!

I listened to the Governor of my home state, Florida, declare our state the freedom state because all the businesses are open and running full tilt.  He cited his success in keeping deaths from coronavirus low while keeping the economy running and jobs available.

I bring this up because on my way to visit my fully vaccinated adult children last weekend I passed by at least 20 overhead electronic road signs proclaiming, “Miami Beach Curfew 8PM – 6 AM Causeways Closed!”  Yes, here it was springtime with Passover and Easter on the horizon and the famed Miami Beach was closing at night.  We are at a critical point in the fight against the Sars2 COVID-19 coronavirus. We are trying to vaccinate enough people quickly so that the virus does not enter a vulnerable host and mutate to a form that the vaccine is less effective against.   We are so close to controlling this pathogen but human nature and failure to be able to delay gratification, and put off travel and group activities, is leading to a potential fourth surge of COVID-19 related illness and death.

My cell phone rang twice with patient calls on the 60-minute trip southward. The first was from a patient whose adult children came to visit him. His unvaccinated eighteen-year-old grandson was with them. After spending four days together they received a phone call that the grandson’s girlfriend was sick and tested positive for COVID-9. The next two calls were from patients who had been to two different Passover seders. One was outdoors, the other indoors with 20 plus guests. Both had been exposed to a person who called the next day to say they were COVID-19 positive.

I watched the director of the Center for Disease Control and Prevention (CDC), an experienced infectious disease and critical care physician, beg Americans to wear a mask and social distance while she was brought to tears by the thought of another wave of illness, death and prolonged restrictions. I listened to the President of the United States plead with state governments to maintain mask restrictions a bit longer to save lives and control the disease. I listened to the Vatican public relations division discuss not holding an Easter Service in St. Peters Square this coming weekend and wondered what it will take to convince people that we just are not ready to resume full activities.

The Governor of Florida is correct. Deaths are down due to vaccinations and the elderly staying home. I suspect if he tracks the cell phones of the tourists and spring breakers to their home states and countries three weeks from now, he will see an increase in hospitalizations and deaths.  Florida’s economy may boom but we certainly are maintaining it at the cost of illness and death elsewhere.

An Oral Medication To Stop Coronavirus?

Researchers have produced a pill that, taken twice a day at the 800 mg dosage for five consecutive days, seems to stop SARS-CoV-2 virus from multiplying and causing clinical symptoms. The work is quite early and needs to proceed through stage 2 and 3 clinical trial phases before it can be presented to the FDA for emergency utilization authorization.

The drug is called molnupirvir. It could be taken in the first few days of infection to prevent advancement to severe disease much like Tamiflu is used with influenza. In initial human trials, the virus was eliminated from the nasopharynx of 49 infected individuals.

Wendy Painter, MD, of Ridgeback Biotherapeutics presented the data at the Conference on Retroviruses and Opportunistic Infections. The drug works by interfering with the virus’s mode of reproducing and mutating – overloading the virus with replication and mutation until the virus burns itself out and can no longer make effective viral copies.

Their method of testing the drug was to administer it, or a placebo, to humans who were infected and in the early stages of symptomatic disease. They used three different dosages and swabbed the participants’ nose and cultured for the virus at different times during the experiment.

At day 5, after the onset of symptoms, there was no detectable infectious virus in the nasopharynx of participants who were treated with molnupiravir. Dr. Painter reminded everyone that the next test will be given to patients who are actually sick with COVID-19 and see if it works. This preliminary data should encourage us that when scientists are given the time and resources, they solve problems. Imagine in the near future a vaccinated society that has at its disposal accurate and reliable quick tests for COVID-19 and the availability of a pill taken twice a day, for five days, to prevent the disease from becoming severe and requiring hospitalization.

Obstructive Sleep Apnea Surgery vs. CPAP? Daytime Anti-Snoring Device?

Obstructive sleep apnea is now epidemic in a population where it runs hand-in-hand with obesity, which is also an epidemic. The consequences of untreated sleep apnea include daytime somnolence, cardiovascular, neurological and endocrine complications.   One of the hallmark signs of obstructive sleep apnea (OSA) is snoring. 

The US Food and Drug Administration (FDA) recently approved an oral device to be worn during the daytime to reduce and/or eliminate snoring. The device is called eXciteOSA made by Signifier Medical Technologies.  The device is a prescription item which will be used by sleep specialists, dentists and ENT physicians.  It has four electrodes that deliver a series of electrical stimuli to the tongue with rest periods in between. The stimulation over time improves tongue function preventing the tongue from collapsing backward into the airway and obstructing it during sleep.  The device is used for 20-minutes once a day, while awake, for six weeks and then once a week thereafter. It is designed to be used in adults 18 years of age or older with snoring and mild OSA. Think of it as physical therapy for the tongue.

The device was tested on 115 patients, 48 of whom had mild obstructive sleep apnea plus snoring. The others were all snorers. The snoring was reduced in volume by more than 20% in 87 of the 115 patients. In the group of patients with the diagnosis of OSA and snoring, the apnea-hypopnea index score was reduced by 48%

It is recommended that a thorough dental exam be performed prior to trying this device. The major side effects noted from its use were excessive saliva production, tongue discomfort or tingling, metallic taste, jaw tightening, tooth filling sensitivity.  No mention of the cost was included in the printed review.

The online journal Practice Update reviewed a JAMA Otolaryngology publication on the use of surgery to treat Obstructive Sleep Apnea versus using a CPAP machine. There are many patients who just can not wear the CPAP mask which is the first-line “gold standard” for treating OSA.  Most patients who spend 90-days adjusting to the mask sleep far better and look forward to using the device to obtain a restful night’s sleep. The study looked at patients who were at high risk for not being able to adhere to a CPAP use regimen. Soft tissue surgery to the uvula was found to reduce the rates of cardiovascular, neurological and endocrine systemic complications compared with prescriptions for CPAP in patients less likely to adhere to or use the CPAP mask. 

The takeaway message is clear. When a patient is unlikely to adhere to CPAP mask use offering soft tissue oral surgery should be offered early while treating the disease.

Tea Can Help Lower Your Blood Pressure

Researchers at the University of California, Irvine, led by George Abbott PhD and Kaitlyn Redford, published their findings in Cellular Physiology and Biochemistry explaining why and how tea lowers your blood pressure. They found that two flavonoid type compounds found in green and black tea activate a specific type of ion channel protein named KCNQ5 which allows potassium ions to diffuse out of cells to reduce cellular excitability. The two catechin type flavonoids acting on KCNQ5 in the smooth muscle of blood vessels relax these blood vessels.

Scientists have previously found that tea can reduce blood pressure by a small amount. Their discovery of the role of the KCNQ5 protein now gives pharmaceutical developers a target for future medications. Hypertension is present in one third of adults in the world.

Tea has been consumed for over 4,000 years and two billion cups a day are consumed worldwide. Next to water it is the most common liquid consumed on the planet. It all comes from the leaves of the evergreen species Camellia sinensis with a difference in the fermentation process producing either green, oolong or black teas.

In much of the world, tea is consumed with milk mixed in. Dr Abbott’s group found that in the laboratory when milk was added to the teas it negated the effects of the KCNQ5 protein. They additionally found different temperatures of the tea resulted in different effectiveness of the KCNQ5 protein. Professor Abbott noted however that in humans’ digestive tracts our stomach and intestines separate out the milk products from the active KCNQ5 protein allowing it to work. He also noted that with our body temperature being about 37 degrees centigrade, the positive effects of the tea continued to work independent of whether you consumed hot tea or iced tea.

The message from this research is that a cup or two of tea per day will help lower your blood pressure.

Foreign Dependence on the Drug Supply Chain

I have written often about the problems we have as a nation being dependent on foreign nations for the raw materials and manufacturing of common everyday drugs and supplies. The COVID-19 pandemic has only amplified that problem as the U.S. compete for supplies against nation states for needed drugs to treat the infected and prevent transmission. I have addressed how many common drugs are manufactured in China, India and Israel and, due to financial cutbacks for FDA inspections, production plants have not been inspected for years.

I have also addressed how a hurricane that destroyed Puerto Rico left the only intravenous solution producing factory in North or South America unable to function – leaving hospitals and the military short of vital materials for health care. We witnessed the shortage of personal protective materials including masks, face shields, gloves, sanitizers, etc. as the coronavirus spread through the Americas with businesses and states bidding against nations for a limited supply of products, preferentially kept in the nation they were manufactured in.

This past Wednesday, President Biden issued and signed an Executive Order directing Federal agencies to study ways to secure the supply chain for pharmaceutical goods and manufactured goods. The Executive Order will direct 100-day reviews for supply chains for pharmaceutical goods, computer chips, large capacity batteries like those used in electrical cars to prevent dependence on foreign governments. The studies call for “consulting with experts in private industry, academia, workers and communities”.

The hope is we will create manufacturing diversity and redundancy bringing some manufacturing home but insuring that one nation or one site will not be responsible for the total production of any vital product. In my view, this is a long overdue step in the right direction based on what has transpired in the recent past.

Vitamin D & Cardiovascular Health

The online journal Practice Update reviewed a publication in the Journal of the American College of Cardiology which basically says excessive calcium supplementation may harm your healthy heart. It was published at a pertinent time because it came while I was trying to convince my post-menopausal wife that between her Vitamin D pearls, calcium, Vitamin D pills and her multivitamin she was taking too much Vitamin D. Her measured 25-hydroxy Vitamin D level came back at 63.

Vitamin D is a fat-soluble vitamin like vitamins A and K. Extra doses of fat-soluble vitamins are stored in the body’s cells and can reach harmful and toxic levels. The normal level of Vitamin D measured by a standard blood test is considered to be 20 or greater by the World Health Organization. In North America it was originally higher at 28 then raised to 30. The Covid-19 Pandemic has raised issues about low levels of Vitamin D being a risk for catching the disease, and developing complications, but no one has defined what levels are considered unsafe.

The National Academy of Medicine, after reviewing this data, has set these limits and levels:

  1. Deficiency is less than or equal to 12ng/ml
  2. Inadequacy is 12-20 ng/ml
  3. Adequate is 20-50 ng/ml
  4. Risk of Adverse Effects occurs at > 50ng/ml

The data suggest avoiding supplementation unless the 25-hydroxy Vitamin D level is <20 and probably best reserved for <12 ng/ml.

Calcium is best absorbed when accompanied by Vitamin D .  Taking smaller doses like 500 mg plus 1000 of Vitamin D3 works. For osteoporotic patients they suggest 600mg of Calcium plus 1000 IU of Vitamin D3 daily. They want you to eat a diet that supplies another 600 mg of calcium a day plus walk for weight bearing exercise and get 15 or more minutes of sunlight daily. Of interest was the statement that calcium supplements may harm your heart, but any calcium obtained naturally through foods does not.

The article was reviewed and commented on by David Rakel, MD, FAAFP with the take home message being, “Eat a high-fiber, plant-based diet with some fish and go outside and play.”

Can Smartphones & Fitbits Interfere with your Pacemaker or Defibrillator?

The February 8th edition of Medpage Today, an online magazine, published the concerns of cardiologist and electrophysiologist Joshua Greenberg, MD, about the magnet arrays in the new Apple iPhone 12 interfering with the function of pacemakers and defibrillators.

When a patient goes to their doctor, cardiologist, electrophysiologist, etc., and the physician wishes to turn off their pacemaker to look at the heart’s normal electrical activity, they normally place a magnet over the implanted device to deactivate it. The new iPhone 12 apparently uses an array of magnets around a wireless charging coil.

Dr Greenberg used the iPhone 12 to disable a Medtronic ICD. Once he brought the phone over the patients left chest the device deactivated. His findings were published in January in a letter to the editor of the journal Heart Rhythm. “This is a big deal because if the patient were to go into ventricular tachycardia or fibrillation during this time, they would just drop dead without receiving a life-saving shock from the ICD.”

Separately, electrophysiologist M. Eskander, MD tweeted a video showing an iPhone12 shutting off a pacemaker as well as if a magnet had been placed over it. Wristband magnets in Fitbit and Apple iWatches have been reported to deactivate Medtronic ICDs from 0.9” away due to their wristband magnets.

Phil Mar, MD , an electrophysiologist at Saint Louis University School of Medicine agrees that this is a previously unrecognized issue that needs to be dealt with. He suggests patients with implanted pacemakers and ICDs avoid purchasing an iPhone with magnets. He encourages their spouses or bed partners to follow the same advice to prevent deactivation when they roll over and get close. He emphasizes that this was not an issue with earlier model iPhones which didn’t have an array of magnets and was not seen in Apple iWatches without the magnetic wrist bands for charging. He is concerned that any cell phone, wrist band or watch using wireless charging may cause the same deactivation.

The author of the article, Anthony Pearson, MD made the suggestion that patients with pacemakers and ICDs should have their cardiologist or electrophysiologist routinely test their cell phones, Fitbits and iWatches’ effect on their devices at a planned routine visit and certainly immediately after implantation. He reminded us this does not occur in devices that do not have a magnet array which is most cell phones and watches.

There has always been a recommendation that if you have a pacemaker or AICD you use your cellphone in the ear opposite your pacemaker or device pocket and never bring it within six inches of the device.
