Aerobic Training Helps Blood Pressure Medications Do Their Job

We are always looking for ways to stay healthy with less medicine.  Miguel Ramirez-Jiminez, PhD of the  University of Castilla-La Mancha, Toledo, Spain presented a paper to the American College of Sports Medicine recently week and addressed this topic.

His group looked at 36 obese and overweight adults who normally did less than 120-minutes of physical activity per week. Ages ranged from 53 – 65 years with 22% postmenopausal women. They had all been taking blood pressure medications for at least eight years and all met the criteria for having the metabolic syndrome which includes hypertension, elevated blood glucose, elevated triglycerides and a large waist.

The group was randomly divided into a placebo group whose medication was stopped or a trial group who continued their antihypertensive medications for the next three days. All participants then underwent 24-hour ambulatory blood pressure monitoring. All the participants were then entered into a four-month cycling program three times a week. 

After completing the four months of cycling training the placebo group again did not receive their medications for three days while the trial group did.  Twenty-four-hour ambulatory blood pressure was then checked in both groups.

The group exercising plus taking their medications saw an average drop in blood pressure of 3-5 mm Hg in addition to the 5mm Hg noted just from the medication’s pre-exercise training. When the exercise program stopped, the extra drop in blood pressure additionally dropped. There is a phenomenon known as “post exercise hypotension” that can reduce your blood pressure for up to 24 hours after training. This is the reason experts advise 3-5 exercise sessions per week.  

The study also revealed that if you exercise aggressively, and hope to permanently stop your blood pressure medications, your pressure usually rises above acceptable levels.  Exercise is not a substitute for prescribed blood pressure medicines. The article can be found at www.medscape.com  

A New Device To Protect the Brains of Athletes From Head Impact

As a parent of athletic girls who played competitive soccer and other sports that involved using your head to control a kicked or thrown ball, I always knew that studies of the brain of European professional soccer players showed much of the same brain injuries seen in professional boxers. We also saw several goalies diving to prevent a ball from entering the goal collide and hitting their heads with the goal’s metal side supports or with an opposing player. Several of the team parents and I tried to design a protective helmet for youth soccer but we never came up with anything that FIFA, the soccer world’s governing body, would allow to be worn during a game.

I played high school football, and a year in college, once suffering a concussion requiring an overnight hospital stay. Later in life as a physician I have followed the discovery of traumatic brain injuries and long-term permanent brain damage in football players, hockey players, soccer players and our military in combat. I wondered when the same creative humans who can send men to the moon and back would design items to protect the brains of competitive athletes.

Q30 Sports Science, LLC apparently has. They received FDA approval for their Q Collar which is designed to prevent deep tissue brain injury from head impacts. The Q Collar is already being marketed and used by athletes in Canada.

The Q Collar is a neck brace worn for up to four hours a day. It was designed after looking at woodpeckers head battering rams and trying to determine why, with all the head trauma they sustain, they do not develop CTE or other permanent traumatic brain injuries. Human brains are suspended in protective fluid inside a bony skull. The force of our head neck and shoulders colliding with a person or object allows our brains to slosh around unrestrained inside the skull and often hitting the extremely hard bony skull bones.

The Q collar increases the blood volume in our internal jugular veins causing a much tighter fit of the brain within the skull and preventing the movement or slosh. By reducing the movement of the brain within the skull it protects the brain from head impact injuries.

The collar was tested on a high school football team who wore state of the art football helmets plus an accelerometer which measured every impact the head sustained during play and practice. There were 284 participants with 139 athletes wearing the Q collar and 145 did not. Each athlete underwent a preseason specialized MRI study of the brain and a post season study. This allowed researchers to look to deep tissue brain injury that occurred over the course of that season. Significant changes were found in the deep tissue of brains on 106 of the 145 (73%) of the participants in the non-Q collar groups. No significant changes were found in 107 of 139 (77%) of the group who wore the Q collar.

The Q collar can be worn for four hours at a time and should be replaced every two years. No pricing data have been released but the intention is to sell the device directly to consumers. The National Institute of Neurological Disorders and Stroke states that in any year there are 1.6 million to 3.8 million traumatic brain injuries related to competitive and recreational sports.

As a parent I would want my child to be wearing this type of device when they engaged in sports that had head impact injuries as a potential side effect. It will remain to be seen just how effective this type of device will be in other recreational activities such as skiing, snowboarding, biking, riding scooters or skating and; will it have an impact in the military on blast injuries? Will insurance companies require such a device for contact sports?

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.

Do Cipro and Levaquin Cause Abdominal Aortic Aneurysms?

Melina Kibbe, MD, of the University of North Carolina Medical Center at Chapel Hill published an article in JAMA Surgery reviewing any possible relationship between taking fluoroquinolones antibiotics such as Cipro or Levaquin and the subsequent development of an abdominal aortic aneurysm.  An aneurysm is a weakening in the wall of a blood vessel that balloons out like the defect on a damaged tire or basketball and has the potential to rupture causing exsanguination and sudden death. Dr Kibbe is also the editor of JAMA Surgery.

The study looked at health insurance company data on antibiotics and aneurysm diagnosis and repair.  They found that 7.5 aneurysms formed per 10,000 fluoroquinolone prescriptions filled at 90 days. This was significantly higher than the 4.6. per 10,000 aneurysms formed after patients took non-fluroquinolone antibiotics.  Patients filling fluroquinolone prescriptions were more likely to undergo repair of aneurysms than those who took other types.

The study used data from IBM MarketScan health insurance claims from 2005 to 2017 in adults aged 18-64.  The study included data on 27,827,254 individuals. The data did not include smoking or hypertensive history or family history of vascular disease. The authors were hoping the FDA would require a warning or caution to high-risk individuals for developing an aneurysm.

We already see an increase in ruptured tendons in patients taking fluroquinolones – especially women who have taken corticosteroids. They are also associated with C difficile colitis, nerve damage, emotional health issues and low blood sugar events. 

Despite these known draw backs to these medications, patients continually demand to have Cipro or Levaquin on hand in case they develop a urine infection or upper respiratory infection or are travelling and concerned about traveler’s diarrhea. 

More research is needed to determine the exact risk of prescribing these medications. Should we be doing scans on patients with hypertension and or smoking history who frequently use these drugs to screen for an abdominal aortic aneurysm?  This is a question that will be addressed by a study soon.  While the research is in process, we need to make sure that our prescribing of these antibiotics is the safest choice for our patients.

The COVID-19 Vaccine Is Becoming More Available. Exercise Patience.

COVID-19 vaccine preparations are arriving in South Florida with several hospital systems opening appointments for men and women 65 and older to receive their first injection. Some will receive the Pfizer product, others the Moderna product. If you wish to travel to Dade County go to https://jacksonhealth.org/keeping-you-safe/  and sign up for the vaccine. They are taking appointments.  West Boca Medical Center and Boca Regional Hospital have opened appointments for non-employed medical staff members and their office staffs to receive vaccine with the hint that the week of January 11, 2021 they will start vaccinating community members.  

There is a sense of urgency and panic in the community about not having access to the vaccines. That is unnecessary and raising the stress level inappropriately.

After you receive your first vaccine dose you will still need to avoid crowds, social distance, wear masks and practice impeccable hand washing hygiene because you will not be immune. Twenty-one to 28 days later you will receive your booster shot and it will take about two weeks before we can detect antibodies to COVID-19 if you develop immunity.  You will have peace of mind, but won’t know if the vaccine prevents individuals from catching COVID-19 when exposed completely?  Will they get COVID-19  and have a very mild case because of the vaccine prevention?  Will these people be contagious to others? We do not know the answers to these questions yet.

If you get the vaccine, develop immunity and are exposed to someone with COVID-19, will you possibly transmit the virus to others without you yourself becoming ill?  No one knows the answer to that question yet either.  If everything goes perfectly well, and you develop a protective shield of immunity like a comic book superhero shield or cape, how long will that last?  Nobody knows that answer either.

The point is the vaccine is coming.  Once vaccinated we will still have to behave the same as before until the answers to these questions are known!  Please be patient.

COVID-19 Vaccine Availability

Update January 4, 2021

Last week the Florida Department of Health discussed providing the Moderna vaccine to our office for staff members who wished to receive the vaccine. Our office manager, Judi Stanich, requested enough vaccine to cover the entire practice. We were told we would have a confirmation this morning.

This morning we learned the vaccine isn’t available yet. The vaccine comes in vials of 10 shots. The vials are kept frozen and can remain active in that state or in a refrigerator for 30 days. Once a vaccine vial is opened the entire vial must be used in under six hours or it degrades.

Moderna and the Florida Department of Health require patients to complete legal release forms for the vaccine. They must then be registered into the Florida Shots data bank and a national data bank. That is one of the reasons patients are asked to bring their driver’s license with them.

If you have had a severe allergic reaction to any medication the Pfizer and Moderna mRNA vaccines may not be best for you. If you have ever had to use an Epi Pen or have been treated for anaphylaxis these shots are not for you. The Astra Zeneca Oxford vaccine and the Johnson and Johnson vaccine are thought to be more suitable for those individuals

After receiving your shot, you will need to be observed by medical staff for 15 minutes to look for adverse reactions. You will be given an instructional sheet on how to register with V-SAFE which is a CDC vaccine monitoring app. Every day, at about 2:00 p.m., you will receive a text message with questions about how you feel related to the vaccine.

Medical malpractice insurance companies have not yet formally announced whether physician insurance policies will cover administration of this vaccine in their offices because none have been FDA approved. The Pfizer and Moderna vaccines have received FDA Emergency Utilization Authorization (EUA) which is not the same as approval.

Currently the only avenue to obtaining the vaccine in Palm Beach County is to try and get through on the 561.625.5180 phone number or leave your demographics on an email at CHD50Feedback@Flhealth.gov. Baptist Health System is planning on opening reservations for seniors 65 years of age and older the week of January 11 working with Boca Regional Hospital, Bethesda Hospital and the FAU Schools of Medicine, Nursing and their EMT program. They have not announced how to make a reservation or if they will be using the data from the Palm Beach County Department of Health through the phone number and email address provided above.

I suspect that by the middle of February there will be plenty of vaccine available locally including the Astra Zeneca Oxford product and the Johnson and Johnson products. In the meantime, remain patient and continue to avoid crowds and continue to social distance, wear suitable face masks and keep up the hand hygiene. Please remember that after you complete your vaccinations (two shots for the Pfizer and Moderna Products) we will not know how much immunity the shots will provide and for how long.

We additionally do not know if successfully vaccinated individuals are completely immune or partially immune if they are exposed to the virus. Furthermore, we don’t yet know if you are vaccinated whether you can carry the virus and transmit it to someone else even if you don’t have any symptoms.

Getting the vaccine will not be a reason to resume activities at crowded gyms, crowded bars or go on that cruise ship just yet. The hope is that by the summer 2021 we will have the answers to the many unknowns.

Keep Your Guard Up As The New Year Approaches

As we head into the last work week of the horrendous year 2020, my advice to my patient population is keep your guard up. Most of you have social distanced, worn masks, washed your hands until they are raw and avoided close contact in a social setting with friends and relatives to avoid contracting or transmitting the coronavirus to others.

I have been receiving phone calls for the last several weeks now from patients who have younger family traveling to Florida by commercial airlines or driving by car for the holidays and they ask me about how to stay safe. I applaud them for their common sense and decency after months in virtual isolation and advise them to continue their social distancing, hand hygiene and wearing masks.

If your family members do not have 14 days to self-quarantine from you upon their arrival, and prior to their visit, then there is a risk of contracting the disease from an unknowing asymptomatic carrier. Make sure the visit is outside in a well-ventilated area with at least 10 feet between individuals and you are all wearing up to date functioning face masks. If a meal is involved, make sure not to serve buffet style and don’t share food from each other’s plates.

If your visitors are feeling well and have no symptoms of illness and wish to try the short seven-day quarantine with testing for COVID, I suggest the standard nasopharyngeal or saliva PCR tests sent to a lab because they are more accurate in this situation than the quick tests. The test sites at FAU (they take walk-ins but are closed on Mondays) or the Town Center Parking Lot test site are professional.

In a few weeks, the Ellume home test kit should start to appear in pharmacies and its results even in asymptomatic individuals is remarkably accurate and quick. That test is a game changer.

Many of us have stayed out of restaurants and bars, avoided theaters and shows, postponed travel and worn masks now since late February. The vaccines are beginning to appear in the area and there will be an opportunity over the next few weeks to receive it. I will provide more details when they are made available to me.

Happy New Year to you all. May 2021 be sweet – filled with joy and health.  But please, until we have you vaccinated, stay strong and keep your guard up!

Will I Be Able to Choose My COVID-19 Vaccine?

There are currently four vaccines to prevent COVID-19 in the pipeline. I have been asked numerous times when am I going to have the vaccine in my office and which vaccine should individuals take? This question was addressed by MedPage Today, an online health care periodical on 11/27/2020. The same question was asked of National Institute of Health “chief” Francis Collins, MD, PhD last week at a press briefing. Dr Collins responded there will not be enough vaccine available in December for the whole country and “people who get offered one should feel quite happy about that.” Leana Wen, MD, of George Washington University responded to the same question saying, “Initially there won’t be nearly enough vaccines for hundreds of millions of Americans. We will probably take whatever we are able to get access to.”

If you are a healthcare worker, or in the more vulnerable groups, you are most likely to be offered one of the nRNA vaccines from Pfizer/BioNtech or Moderna because they are further along in completing the FDA required trials and application process for approval. Younger healthier individuals having less priority may get to choose.

Larry Corey, MD, a viral expert at Fred Hutchinson Cancer Institute in Seattle and a leader of the COVID-19 Prevention Network Vaccine Program broke down the numbers at a November 18, 2020 meeting of the American Public Health Association and National Academy of Medicine:

  1. The US Government has contracts for 100 million doses of the Pfizer/BioNTech and Moderna vaccines with production producing the 200 million doses by the spring of 2021. That should cover the highest risk groups including healthcare personnel, nursing home residents, essential workers and the medically vulnerable per the CDC Advisory Committee on Immunization Practices (ACIP) guidelines. The vaccine will be shipped to 50 states, the District of Columbia, 8 territories and five large urban health departments including NYC and Chicago. Who receives it first, and where they receive, it will be decided by the local jurisdictions. This process should take until the end of March 2021 leaving some 200 million Americans waiting for a vaccine. Dr. Corey was clear that “We need other vaccines for the rest of the population.”
  2. In addition to the Moderna and Pfizer/BioNTech mRNA vaccines, there are products from Oxford/AstraZeneca, Janssen/Johnson &Johnson, Merck, Sanofli/Glaxo SmithKline and Novavax. Jay Butler, MD, deputy director for infectious disease at the CDC expects there to be mass vaccinations run by public health agencies and possibly some vaccination programs at community pharmacies. No mention was made of supplying physician offices or clinics.
  3. If there are no major delays, seven different vaccines should be available by the spring of 2021. Naor Bar-Zeev, PhD, of the International Vaccine Access Center at Johns Hopkins University in Baltimore said it is too soon to compare the products because there are no studies comparing them head-to-head. He reminded us that different vaccines might be better suited for different patient populations with pediatric patients, the elderly, the immunocompromised likely to do better with some and not others.

Despite the lack of detail to date, Moncef Slaoui, MD, head of the federal Operation Warp Speed, told CNN that he expects 70% of the US population to be vaccinated by May 2021.

New Drug Shows Weight Loss Promise – Just in Time for the Holidays

Thomas Walden, PhD of the Department of Psychiatry, Perelman School of Medicine, University of Pennsylvania presented data on weight loss at a Bariatric Medicine meeting held remotely called ObesityWeek. It was reported this week on Medscape Medical News.

Using the diabetic drug semaglutide (Ozempic), they demonstrated that 75% of the 611 participants lost 10 % or more of their baseline body weight. When they used the higher diabetic dosage, 55% of the participants lost more than 15% of their initial body weight and 36% lost greater than 20%.

Diabetic drugs have been used off-label for years for weight loss. Byetta and Trulicity work to reduce weight as well. The real problem with these medications is cost – with a month of Ozempic costing $800 – $900 while the other two (Trulicity and Byetta) are more expensive than that.

We know weight loss helps diabetics and hypertensives improve their control and health but there are a limited number of drugs you can safely give a 55 year-old with these types of medical conditions. I was surprised and perplexed when a local bariatric specialist started my 64 year-old patient on an amphetamine for three weeks with their heart rate accelerating and blood pressure elevating characteristics.

In patients, 55 or older, I believe in nutritional counseling first. We have experienced dietitians locally both at our hospitals and private practice who will teach you how to eat correctly and work you to develop a personal weight loss plan.

The retail diets like Weight Watchers, Jenny Craig and NutriSystem work and are safe. However, not all retail diets provide behavioral coaching which is a crucial component for losing weight safely and maintaining the weight loss (not yo-yo dieting).

I have twice now experienced great success with OPTAVIA.  The program incorporates Healthy Habits which is an innovative and proven lifestyle approach which gets your mind and body working together.  A health coach provides you with personalized guidance for maximum effectiveness.

Their plan uses five of their “fueling meals” plus one “lean and green meal” you prepare per day.  Following their plan, I have lost more than 35 pounds, in just three months.

I have recently signed up to be an OPTAVIA coach for those patients interested in this program and requiring help and encouragement along the way. Losing the weight is always easier than keeping it off for a “foodaholic” like me but with their maintenance program, and hopefully some discipline, I will keep it off this time.

Happy Holidays to all my patients, colleagues and friends. If you would like to shed those extra pounds, and live healthier, just give me a call. We will discuss the program and how you would benefit from it.

Advances in Prostate Cancer

Should we get a routine PSA on men at risk for prostate cancer? This debate has been raging for the past few years with the United State Preventive Task Force coming out against screening men for prostate cancer because if the PSA is elevated the subsequent diagnostic testing is painful , expensive and comes with many complications.

The specialty societies representing urologists, especially amongst European physicians, show a drop in deaths from prostate cancer since they started annual screening using PSA blood tests in senior men. When we find an elevated PSA, ultimately, the gold standard was the ultrasound guided biopsy through the rectum performed by urologists in their offices, which was both uncomfortable and accompanied by a post procedure infection at times. That has changed with the introduction of the MRI of the prostate which can detect prostate cancer. If the MRI is negative, then, in most cases, even if there is microscopic prostate cancer present, it would be treated with watchful waiting not surgery or radiation. If something is seen, biopsy interventional radiologists are now able to biopsy the prostate through the perineum under local anesthesia which is less painful and carries fewer post procedure complications.

If prostate cancer is found and the pathology and grading of the specimen indicates a significant risk of spread of disease we now have the capability of using the PET scan with gallium 68 PSMA-11 which targets prostate specific membrane antigen and highlights metastatic disease. This agent was approved by the FDA recently after studies at UCLA Medical Center and University of California San Francisco were reviewed. It has a second use in detecting recurrent disease in men already treated for prostate cancer who now have a chemical increase of their PSA but no detectable mass or lesion on imaging studies.

Radiologists have been using F-18 fluciclovine and or C-11 Choline as imaging enhancers, but these were not as effective as the Ga-68-PSMA just approved. By identifying areas of recurrent disease, it may allow physicians to locally treat the recurrent areas directly. Trial investigator Jeremie Calais, MD, of UCLA feels “Because the PSMA PET scan has proven to be more effective in locating these tumors, it should be the new standard of care for men who have prostate cancer, for initial staging or localization of recurrence.” Peter Carrol , MD, of the University of California, San Francisco added, “I believe PSMA PET imaging in men with prostate cancer is a game changer because its use will lead to better, more efficient and precise care.”
