Common COVID-19 Misconceptions Linger Three Years Later

, , COVID

It’s been three years since the first cases of COVID-19 were diagnosed in the U.S., but our concierge primary care doctors in Jupiter are still hearing comments from friends, acquaintances, and even some of our patients that are just plain incorrect.

For instance, we were talking to someone the other day whose wife was very sick with COVID-like symptoms: body aches, severe cough, fever, chills, and so on. When we asked if she’d been tested for COVID-19, he replied, “No, she’s already had it.”

We happen to know that her previous infection was a year ago when the delta variant was the predominant strain. Today, it’s the XBB.1.5 subvariant of the omicron variant. And as with the flu, which is also a virus, it is possible to get COVID-19 more than once, even if you’ve been vaccinated (which she hasn’t).

The problem with his not knowing this is that she could have received the antiviral pill Paxlovid or similar medication early on to lessen her symptoms, instead of spending over two miserable weeks in bed. By the time we talked, it was too late—you must receive the treatment within the first five days.

Understandable Confusion

Of course, much misinformation spreads wildly on social media. And it’s not just misinformation, but dangerous, outright fabrications. For example, Dr. Anish Agarwal, an emergency physician in Philadelphia, recently told the New York Times he’s still seeing patients who believe what he called “crazy” claims that the COVID vaccines “will insert robots into their arms.”

“We battle that every single day,” he told the paper.

We believe our patients are savvy enough to discount such craziness and hope they will check with us if they read something like this that concerns them.

But many of the misconceptions we hear arise because people are busy and don’t have time to keep track of all the news about the coronavirus, or they make assumptions based on misunderstandings like our acquaintances did.

So here’s a capsule summary of the facts we know about COVID-19 and the vaccines. Again, we hope you’ll contact us with any questions.

COVID-19 Facts

Yes, COVID-19 is still a threat, in some regions of the country more than others, especially the Northeast and Midwest. Hospitalizations, including here in Florida, have declined in recent weeks. But according to an NBC News tracker, the U.S. is still averaging 524 deaths from COVID-19 every day, including 63 Floridians.

And of course, hundreds of thousands of Americans are still dealing with the devastating effects of long COVID, and while we’re learning more all the time, we still don’t have a cure or effective treatments.

Despite a recent study that seemed to question the effectiveness of wearing face masks in public places, numerous studies have found they do work, not only to help prevent the spread of COVID-19 but also to protect the wearer.

The most recent study, conducted by the California Department of Public Health and published in the CDC’s journal Morbidity and Mortality Weekly Report, showed that those who reported wearing masks were about half as likely to become infected than those who didn’t. The analysis found the odds were even lower for those who reported masking “all of the time” vs. “some” or “most of the time.”

Other studies conducted over the course of the pandemic showed infection reductions from wearing well-fitting masks as high as 70-80 percent.

Vaccine Facts

COVID-19 vaccines are safe and effective. Adverse events connected with the vaccines are infrequent:

  • Myocarditis (inflammation of the heart muscle) associated with the mRNA vaccines occurred in 1,626 people out of 192,405,448 participants in one study.
  • Thrombosis (blood clots) associated with the Johnson & Johnson vaccine occurred in four out of one million people who received the vaccine.
  • And cases of both myocarditis and thrombosis were higher in those who contracted COVID-19 and hadn’t been vaccinated.

Vaccines often don’t prevent minor or even severe symptoms, but they do reduce the chance of serious disease and death. A research report by the Commonwealth Fund estimated that vaccines prevented 3.2 million deaths and 18.5 million hospitalizations in the U.S. between December 2020 and November 2022.

A primary series (two doses of the mRNA vaccine) plus a booster dose is more effective than a primary series alone; a second booster dose increases protection even better, and so on, because vaccine protection against serious illness begins to wane within four to five months after inoculation. 

Pfizer-BioNTech’s newer bivalent vaccine is more effective against both the original strain and the newer omicron and XBB variants than the original vaccine, according to a November 2022 study.

One 2022 study also found that vaccination reduces the risk of developing long COVID.

Vaccines also help to prevent transmission of the virus, as a November 2022 study found. In January, Forbes reported that those who had received the vaccine were 24 percent less likely to infect close contacts than those who were unvaccinated; those who had been previously infected were 32 percent less like to spread the virus; and those who had been vaccinated and previously infected were 41 percent less likely to transmit the virus. 

Keep in mind that even after three years of experience with the novel coronavirus, there’s still much we don’t know. But what we do know is based on solid, extensive, worldwide research, not on wild supposition or hearsay passed along on the Internet.

Here’s to Your Heart Health

, , , Disease, Health Basics, Healthy Living, Nutrition, Preventative Health

In recognition of American Heart Month in February, our primary care concierge doctors in Jupiter thought we’d share some facts with you about your heart, and what you can do to keep it healthy.

Surprising Heart Facts

First, from the Cleveland Clinic, here are a few interesting things you may not know about your heart.

Your heart is about the size of your two hands clasped together.
It beats 100,000 times a day.
The beating sound is the clap of valve leaflets opening and closing.
A woman’s average heartbeat is faster than a man’s by almost eight beats a minute.
Every cell in your body gets blood from your heart, except for your corneas.
The heart pumps blood through 60,000 miles of blood vessels.
A normal heart pumps approximately four tablespoons of blood with each beat.
Each minute, your heart pumps 1.5 gallons of blood.
Your heart has its own electrical supply and will continue to beat when separated from your body.
Heart cancer is very rare because heart cells stop dividing early in life.

About Heart Disease

Heart disease is the leading cause of death for men, women, and people of most racial and ethnic groups in the U.S. About 697,000 people in the U.S. died from heart disease in 2020 (the most recent figures available). And every year about 805,000 people in the U.S. have a heart attack; over 600,000 of those are first heart attacks.

According to the Centers for Disease Control and Prevention (CDC), the term “heart disease” refers to several types of heart conditions.

The most common type of heart disease in the U.S. is coronary artery disease (CAD), which affects blood flow to the heart. Decreased blood flow can cause a heart attack. In 2020, about 20 percent of deaths from CAD occurred in adults below the age of 65, known as an “early cardiac event.”

Common Symptoms of Heart Disease Include:

Heart attack: chest pain or discomfort, upper back or neck pain, pain in the jaw or throat, indigestion, heartburn, nausea or vomiting, extreme fatigue, upper body discomfort, dizziness, a cold sweat, and shortness of breath
Arrhythmia: fluttering feelings in the chest (palpitations)
Heart failure: shortness of breath, fatigue, or swelling of the feet, ankles, legs, abdomen, or neck veins

The Cleveland Clinic’s Dr. Curtis Rimmerman, a cardiologist, emphasizes that symptoms of a heart attack can vary widely, but adds that the discomfort is usually unrelenting, typically lasting five minutes or more.

“Regardless of where the pain is, people typically can’t find a position that relieves the pain,” he says. “Nor do they find relief by taking a drink of water, popping antacids or taking deep breaths.”

That means it’s time to call 911, he adds.

Increasing Risk

Unfortunately, about one in every five heart attacks are “silent”—that is, the damage is done, but the person is not aware of it.

That’s why it’s important to know your risk factors and what you can do about them.

About half of all Americans (47 percent) have at least one of the three key risk factors for heart disease: high blood pressure, high cholesterol, and smoking.

In addition, several other medical conditions and lifestyle choices also put people at a higher risk for heart disease, the CDC reports, including:

diabetes
overweight and obesity
unhealthy diet
physical inactivity
excessive alcohol use

In addition, a 2021 study published in the journal Heart found that those who used illicit substances, including amphetamines, cocaine, and cannabis, were far more likely to experience an early cardiac event than those who didn’t.

And another study, published in the Journal of the American Heart Association (AHA) in 2020, found that the chances of developing cardiovascular disease (CVD) were 19 times higher in women who consumed one or more sugary drinks a day. This included everything from fruit juices to soft drinks (not diet) to coffee with sugar.

Lowering Risk

Some risk factors cannot be controlled, such as age or family history of heart disease, but you can take steps to lower your risk by changing the factors you can control.

Have your blood pressure, cholesterol, and triglycerides checked regularly.
Ask us whether you should be tested for diabetes.
Quit smoking.
Limit the alcohol you consume to one drink a day.
Learn how to manage stress levels by finding healthy ways to cope with stressful events.

In addition, there are two other ways that have been shown to dramatically reduce your risk for heart disease.

The first is exercise. According to the Cleveland Clinic, regular moderate-intensity exercise for at least 150 minutes is the single most important—and free—key to heart health.

The second is diet, specifically a plant-based diet. This doesn’t necessarily mean going totally vegetarian, just making plant foods vs. animal foods the main component of your diet.

“I’ve seen people whose diabetes, angina, or blood pressure goes into remission [on a plant-based diet],” Andrew Freeman, a cardiologist and the co-founder of the Nutrition and Lifestyle Work Group at the American College of Cardiology, told The Washington Post.

“I’ve seen autoimmune diseases go away when you cut inflammation,” he said. “The best way to do that is with a plant-based diet, and people get better.”

Is a Neti Pot Right for You?

, , Health Basics, Healthy Living, Lifestyle, Preventative Health

Because our concierge primary care doctors in Jupiter have been receiving more questions about the effectiveness of Neti pots for various sinus conditions, we thought we’d take some time to explore their usefulness—and to reiterate a special warning about their use.

What is a neti pot?

Neti pots are one type of nasal irrigation device that use a saline or saltwater solution to treat congested sinuses, colds, allergies, and congestion from flu and COVID-19.

These devices include the teapot-looking container that originated with Ayurvedic medicine in India, along with bulb syringes, squeeze bottles, and more expensive motorized pulsed water devices.

In general, these devices all introduce salt water (saline) into the nostrils to flush out mucus, allergens, and bacteria. The saline helps thin the mucus, making it easier to expel.

The U.S. Food and Drug Administration (FDA) says that such saline rinsing “can remove dust, pollen, and other debris, as well as help to loosen thick mucus. It can also help relieve nasal symptoms of sinus infections, allergies, colds, and flu.

“Plain water can irritate your nose,” the agency says. “The saline allows the water to pass through delicate nasal membranes with little or no burning or irritation.”

How do they work?

 “There are various ways to deliver saline to the nose,” says Eric A. Mann, M.D., and Ph.D., a doctor at the FDA.

“Nasal spray bottles deliver a fine mist and might be useful for moisturizing dry nasal passages. But irrigation devices are better at flushing the nose and clearing out mucus, allergens, and bacteria,” he says.

Information that comes with each device can give more specific instructions, but in general, the FDA says they all work basically the same way:

  • Leaning over a sink, tilt your head sideways with your forehead and chin roughly level to avoid liquid flowing into your mouth.
  • Breathing through your open mouth, insert the spout of the saline-filled container into your upper nostril so that the liquid drains through the lower nostril.
  • Clear your nostrils. Then repeat the procedure, tilting your head sideways to the other side.

While some people experience immediate relief from their symptoms, for others it may take a few days to begin breathing more freely.

And experts caution that—like oral decongestants—nasal irrigation devices are simply a treatment for a symptom, not a cure for the underlying cause.

Some Cautions

Although the FDA says that neti pots and other similar nasal irrigation devices are generally safe, they may not be right for everyone. If your immune system isn’t working properly, the agency advises checking with your healthcare provider before using any nasal irrigation system.

A few users report ear discomfort, nasal irritation, a burning or stinging sensation, and even nosebleeds. But in general, the FDA considers them safe to use, even for children aged two and up.

The most significant warning, however, concerns the type of water used in them. 

“Tap water isn’t safe for use as a nasal rinse because it’s not adequately filtered or treated,” the FDA cautions.

“Some tap water contains low levels of organisms—such as bacteria and protozoa, including amoebas—that may be safe to swallow because stomach acid kills them. But in your nose, these organisms can stay alive in nasal passages and cause potentially serious infections.”

They can even be deadly, the Centers for Disease Control and Prevention (CDC) reports. Since 1993, there have been at least 70 cases of “brain-eating” amoeba infections in the U.S., which are “almost uniformly fatal,” the agency reports.

Safe Use

The safety of neti pots and other such nasal irrigation devices—including the motorized versions—depends on the type of water used and how meticulously the containers are cleaned after each use.

The FDA lists the following types of water as safe to use for neti pots and similar devices:

  • Distilled or sterile water, which you can buy in stores. The label will state “distilled” or “sterile.”
  • Boiled and cooled tap water—boiled for three to five minutes, then cooled until it is lukewarm. Previously boiled water can be stored in a clean, closed container for use within 24 hours.
  • Water passes through a filter designed to trap potentially infectious organisms. The CDC has information on these filters here. 

To safely use and care for your device:

  • Wash and dry your hands.
  • Check that the device is clean and completely dry.
  • Prepare the saline rinse, either with the prepared mixture supplied with the device, or one you make yourself.
  • Follow the manufacturer’s directions for use.
  • Wash the device, and dry the inside with a paper towel or let it air dry between uses.

Does it Work?

Most people who use neti pots to relieve nasal congestion and allergies swear by them, especially if they want to avoid using over-the-counter decongestants. 

“Just about any condition that causes irritants and mucus to build up inside the nose will benefit from saltwater rinsing with a net pot or similar device,” Richard Orlandi, a nasal and sinus specialist and professor of surgery at the University of Utah Health in Salt Lake City, told Consumer Reports (CR).

“These include allergies, nonallergic nose irritation, colds, and sinus inflammation and infections,” he said.

The World Health Organization (WHO) reports that rinsing your nose with saline does not prevent COVID-19, by the way.

If saline rinsing doesn’t relieve your symptoms, or if you have a fever, nosebleeds, or headaches while using the devices, let us know.

Nature Can Heal in More Ways Than One

, , , , , , , , Environment, Health Basics, Healthy Living, Lifestyle, Motivation, News, Preventative Health, Uncategorized

Humans evolved in the natural world. We may have retreated to caves or huts to protect ourselves from the elements, but we spent much of our time outdoors, hunting, gathering, cooking, telling stories, and so on. Our lives these days, though, are largely spent cut off from nature.

This way of life has sparked a wealth of studies showing that our loss of contact with nature—dubbed “nature deficit disorder”—has a real impact on our physical and mental health.

So our primary care concierge doctors in Jupiter weren’t too surprised to learn of a new study published this month in the journal Occupational & Environmental Medicine, which found that enjoying nature up to four times a week reduced the odds of needing mental health medications by 33 percent.

It also reduced the odds of using blood pressure pills by 36 percent and asthma medications by 26 percent.

The Study

Researchers interviewed about 6,000 people who live in large cities in Finland, asking about their access to and use of green and blue spaces, including parks, zoos, rivers, lakes, or the sea. 

They also asked subjects whether they could see views of nature from their homes, how often they spent time outdoors as well as how much they exercised while outdoors.

The study also accounted for other possible factors such as traffic-related outdoor air pollution and noise, which have been proven to have an adverse effect on health.

Respondents were then asked about their use of medications for depression, anxiety, high blood pressure, asthma, or insomnia, and correlated these with time spent in nature.

As noted above, the results were markedly better for those who were regularly exposed to green or blue spaces. Notably, those who lived in areas with a lot of green spaces or who simply looked at nature from their windows showed no improvement in any of these categories.

“Frequent green space visits, but not the amounts of residential green or blue spaces, or green and blue views from home, were associated with less frequent use of psychotropic, antihypertensive, and asthma medication in urban environments,” the study authors wrote.

Confirming Prior Research

Numerous earlier studies have found significant benefits from spending time in nature.

One meta-review of 143 other studies published in the journal Environmental Research, for example, found that people with access to green space generally had a slower heart rate, lower blood pressure, and fewer blood levels of the stress hormone cortisol. Researchers also found significantly fewer cases of diabetes and lower rates of mortality from heart disease in the group regularly exposed to nature.

An American Institutes for Research (AIR) study in 2005 found that sixth-grade students who attended three outdoor education programs showed marked improvement in conflict resolution skills.

Another study in China in 2013 involved 60,000 children between the ages of two and 17. It showed that regular exposure to nature, or “greenness” around their schools, reduced the incidence of attention deficit/hyperactivity disorder (ADHD). A more recent study at the University of Illinois produced similar results.

And a 2016 study of nearly 100,000 women conducted over eight years found that having access to the greenest space not only improved the subjects’ mental health but also reduced their death rate by 12 percent.

Nature Deprivation Hurts

Author Richard Louv coined the phrase Nature Deficit Disorder (NDD) in his 2005 book “Last Child in the Woods: Saving Our Children from Nature Deficit Disorder.” In it, he argued that elements of our urbanized lifestyle, including few natural spaces, a car-focused culture, more screen time, changes in the perception of risk (e.g., fear of “stranger danger”), less leisure time, and increased time pressure from work or school, combine to decrease or even eliminate contact with nature for both adults and children, according to the National Institutes for Health (NIH).

“The average young American now spends practically every minute—except for the time in school—using a smartphone, computer, television, or electronic device,” Tamar Lewin reported in a Kaiser Family Foundation study on the subject.

According to the Children and Nature Network (C-NN), which was co-founded by Louv, an expanding body of scientific evidence suggests that nature-deficit disorder contributes to:

  • diminished use of the senses
  • attention difficulties
  • conditions of obesity, and
  • higher rates of emotional and physical illnesses

Make the Connection

Unfortunately, to get back to nature, you may need to make a specific effort, because in our harried lives trapped indoors, focused on our screens, we have very little time for real relaxation.

Therefore, it’s often necessary to add nature breaks to our schedules the same way we schedule everything else.

One way is to undertake the Japanese practice known as “forest bathing,” or shinrin-yoku. As Kaiser Permanente’s’ online Thrive explains, “Heading out to a heavily wooded area isn’t required. You could take a trip to a nearby park, your favorite local trail, the beach, or any natural setting. Just be sure to turn off or silence your phone or other devices.”

Psychology Today explains, “Forest bathing is an antidote to pinging distractions, impending deadlines, and never-ending obligations . . . . The idea is to immerse yourself in a natural environment and soak up the many health benefits of being in the green woods.”

However, you manage it, for the sake of your overall health we recommend you take the time to reconnect with the natural world as often as possible.

There’s a Reason Why You’re Feeling SAD

, , , , , , , , , Environment, Health Basics, Healthy Living, Lifestyle, News, Preventative Health

If you’ve been feeling down, sleepy, or hopeless, even with all the holiday merriment going on around you, our primary care concierge doctors in Jupiter want you to know you’re not alone. Health experts estimate that seasonal affective disorder (SAD), or the “winter blues,” affects about five percent of the U.S. population.

SAD is more than just the “winter blues,” according to the American Psychiatric Association (APA). The symptoms can be distressing and overwhelming, and can interfere with daily functioning, the APA reports. 

Affecting more than 10 million Americans, symptoms of the condition usually begin in October or November and begin to subside in March or April. However, some patients don’t feel fully back to normal until early May.

SAD may begin at any age, but it typically starts when a person is between the ages of 18 and 30 and seems to affect women more than men.

Symptoms

The APA lists the following symptoms associated with SAD:

  • fatigue, even with excessive amounts of sleep
  • weight gain associated with overeating and carbohydrate cravings
  • feelings of sadness or depressed mood
  • marked loss of interest or pleasure in activities once enjoyed
  • loss of energy
  • an increase in restless activity (e.g., hand-wringing or pacing)
  • slowed movements and speech
  • feeling worthless or guilty
  • trouble concentrating or making decisions
  • thoughts of death or suicide or attempts at suicide.

The severity of such symptoms can vary from person to person, and not everyone will experience all these symptoms.

Likely Causes

While no one is certain what causes SAD, the lower amounts of sunlight in fall and winter are believed to lead to a biochemical imbalance in the brain, impacting the body’s circadian clock, which triggers sleep and wake cycles.

This process affects the output of serotonin, the so-called “mood” hormone. Studies have shown that the circadian-related output of serotonin drops markedly with the decrease in light during the winter. It also increases the level of melatonin, a hormone secreted by the pineal gland that regulates the sleep cycle.

The cause of SAD may have an ancient survival connection, as humans learned to restrict activity when food sources were scarce. The tendency may still be hardwired into our biology, and people can experience symptoms on a sliding scale from barely noticeable to full-blown clinical depression.

Risk factors include a family history of SAD or another form of depression, having major depression or bipolar disorder, and having lower levels of vitamin D. Vitamin D is believed to promote serotonin production.

Treatment

SAD can be effectively treated in a number of ways, including through the use of light-box therapy, which employs specially built full-spectrum lamps to alleviate symptoms. The NIMH reports that this type of therapy has been a mainstay for treating SAD since the 1980s.

In this treatment, a person sits in front of a very bright lightbox (10,000 lux) every day for about 30 to 45 minutes, usually first thing in the morning, from fall to spring. The light boxes, which are about 20 times brighter than ordinary indoor light, filter out the potentially damaging UV light, making this treatment safe for most people.

However, those with certain eye diseases or people taking certain medications that increase their sensitivity to sunlight might need other treatment types.

Other approaches include the use of antidepressants such as Paxil and Prozac, or cognitive behavioral therapy (CBT), a type of talk therapy aimed at helping individuals learn how to cope with difficult situations. In addition, the U.S. Food and Drug Administration (FDA) has also approved another type of antidepressant specifically for SAD: bupropion. In extended-release form, it is taken daily from fall to spring to prevent major depressive episodes.

Self-care

Meanwhile, there are steps you can take to help mitigate milder cases.

1. Stay active outdoors

Exposure to early morning light has been shown to be the most effective at reducing symptoms, as has regular exercise. An early morning walk or run might be all you need to help alleviate your symptoms.

2. Let in the light

If you can’t get outside, at least let the sunshine in as much as possible. Open blinds and drapes first thing in the morning, and keep them open all day. If you can, arrange your home or office so you’re exposed to as much sunlight as possible during the day (but remember that the sun’s harmful UV rays can penetrate glass, so use sunscreen if you’re actually sitting in the sun all day).

3. Eat right

Simple carbs and sugars wreak havoc with your blood sugar, thereby affecting your mood. Lean meats, fruits, vegetables, nuts, and complex carbohydrates will help to keep your brain functioning properly.

4. Take it easy

Don’t try to do too much, which can add to feelings of being overwhelmed. Do what you can, and postpone the rest, or ask friends and family for help with your to-do list.

5. Stay connected

Studies have shown that connecting with others helps improve mood: volunteering, getting together with friends and family, and participating in group activities, are some possibilities.

If your symptoms are interfering with your daily life, let us know. We can help evaluate your symptoms and recommend the right therapy.

The Risk of Salmonella in Backyard Chickens

If you’ve been buying cage-free eggs, or eggs from your local farmer, or even raising your own chickens to lower your risk of salmonella, our concierge doctors in Jupiter have some unhappy news for you: Most chickens, ducks, and turkeys carry some form of the more than 2,000 types of salmonella, according to Craig Coufal, Texas A&M AgriLife Extension Service poultry specialist.
