Month: January 2022

I grew up in India with my loving family, living in a 1,000-square-foot room. I was fearless and often experienced the bumps and bruises of an active boyhood. I always got up, dusted myself off, and walked again. I learned resilience and was a happy child.

Throughout my work as a physician, the importance of resilience has resonated. I lead research on the effects of consciousness, meditation, yoga, and spirituality on health. Little did I know my understanding of these issues was going to hit close to home.

Becoming a patient: A transformative day

It was an ordinary day. After long hours at work, I went home to enjoy dinner with my family. I did my daily exercise on the treadmill and relaxed, watching television with my son.

Suddenly, I experienced crushing pain. At first I didn’t want to take it seriously, but this pain was too much to bear and I fell on my knees. My wife quickly called 911, thinking it was a food allergy. When the EMTs arrived, I asked them to take me to the hospital where I work. There wasn’t time for that, they told me.

Those were the last words I heard.

Mindful awareness: Pain, but no suffering

I woke next to the squeaking sound of the bed wheels. I heard my best friend screaming, “I am here!” I felt a severe pain on my left shin. At that moment, I was simply aware of what was happening. The “watching myself” began. Was this a spiritual self-awareness, or the meta-awareness described by neuroscientists?

For the next few hours in the ICU, I had the range of disconcerting symptoms that accompanies a severe heart attack — the type of heart attack that only 5% of people survive. Yet it was like I was watching myself in a movie. While I was aware of profound discomforts that should have been terrifying, I felt no suffering. This experience stands out to me even today.

During my heart attack, I experienced a distance between myself, my body, and my mind. I was the witness of the event, not its victim. I believe that this is the result of a regular yoga and meditation practice that transformed my life forever. The type of yoga I practice emphasizes this distance between mind and body, but such benefits are not unique to any single type of yoga or method of meditation. My personal preference is Sadhguru yoga — you can try a simple Sadhguru meditation exercise here.

Bringing intention to illness

My experience is a powerful reminder that aligning spirituality with health not only can help you stay well, but can help you weather “dis-ease” with more intention.

Facing our own mortality can shake us into acknowledging that our time on this earth is indeed short. It serves up a strong reminder to prioritize the things that matter the most in your life. Before the heart attack, my life was driven primarily through intellectual knowledge. But now, I experientially know that there is much more to life than what my intellect perceives. I ask myself: Have I lived my life to the fullest? What impact have I had on the people around me, the city I live in, and the planet I walk on?

We have no control over what life throws at us. But we have a lot of say over what happens within us. I am grateful to the unbroken chain of resuscitation, science, and, I believe, my spiritual practices. As the new year begins, I’d encourage you to consider making spirituality — however you define it — a part of your health goals.

Just about everyone experiences knee pain at some point in their lives. Most of the time, it follows an injury or strenuous exercise and resolves in a few days, but knee pain can last months or even years, depending on the cause. A new study suggests telehealth programs designed for people with knee osteoarthritis may help ease pain, improve ability to function, and possibly even lead to weight loss.

What is osteoarthritis of the knee?

Osteoarthritis (OA) — the age-related, “wear-and-tear” degeneration of the knee joint — is the number one cause of chronic knee pain, affecting nearly a quarter of people age 40 or older. It’s responsible for most of the 600,000 knee replacements in the US each year, and more than $27 billion in annual healthcare spending.

How is it treated?

No treatment for knee OA is ideal or works in every case. Standard approaches to treatment include pain management, exercise, and loss of excess weight.

For pain, people with knee OA may consider

• anti-inflammatory drugs that are rubbed on the skin, such as diclofenac gel
• anti-inflammatory medicines, such as ibuprofen
• pain relievers, such as acetaminophen
• injections of corticosteroids.

Opiates, arthroscopic surgery, and other injected treatments are not routinely recommended due to risks, lack of proven benefit, or both. Knee replacement surgery has a high success rate for knee OA, but is generally considered a last resort because it’s major surgery that requires significant recovery time.

Virtual visits can help

Before the COVID-19 pandemic, many people with knee OA regularly saw their healthcare providers to

• monitor their pain and ability to function
• consider changes in treatment
• check for treatment side effects
• determine if other problems are contributing to symptoms.

It turns out, much of this can be done virtually. The pandemic made it a necessity. And a new study suggests it works.

What did the study on knee osteoarthritis find?

The study demonstrated that telehealth visits are a good way to provide care to people with knee OA. The researchers enrolled nearly 400 participants who had knee OA and were overweight or obese. They were divided into three groups:

• Group 1 was given access to a website that provided information about OA, including pain medications, exercise, weight loss, and pain management.
• Group 2 received the same information as group 1, and also engaged in six exercise sessions with a physical therapist by videoconference. These sessions lasted 20 to 45 minutes and included advice about self-management, behavioral counseling, and education about choosing exercise equipment.
• Group 3 followed the same format as group 2, and also had six consults by videoconference with a dietitian about weight loss, nutrition, and behavioral resources. These sessions also lasted 20 to 45 minutes.

After six months, participants in groups 2 and 3 reported pain relief compared to Group 1. On a pain scale of 1 to 10:

• group 3 improved more than group 1 by 1.5 points
• group 2 improved more than group 1 by about 1 point.

People in groups 2 and 3 also had better scores for function compared to group 1. All of these improvements were considered meaningful and held up for at least 12 months.

In addition, those assigned to group 3 lost about 20 pounds over the course of the study, while the other groups’ weights were nearly unchanged. That’s an important finding, because excess weight can worsen osteoarthritis of the knee. Losing excess weight can improve symptoms and help prevent the arthritis from getting worse.

Since there was no comparison with in-person care, it’s impossible to say whether these virtual visits were better, worse, or similar to an office visit. In addition, this study did not report the costs of these virtual sessions, the long-term impact of virtual visits, or whether repeated virtual visits could maintain the improvements people reported.

The bottom line

The pandemic is giving researchers an opportunity to seriously study the potential value and limitations of virtual care on a large scale. If these visits are as good as or better than in-person visits for certain conditions and the costs are no greater, that’s a big deal. A virtual visit can eliminate time spent in travel and the waiting room, and possible parking fees that can make a brief doctor’s visit an expensive undertaking that takes half the day. Virtual care also has the potential to reach patients who otherwise cannot get to their doctor’s office.

Of course, telehealth isn’t equally available to everyone due to language barriers, technical abilities, health insurance plans, or simply not having access to smartphones, computers, or data plans. Some states are letting emergency measures supporting telehealth services expire. And some insurers may resort to pre-pandemic rules about coverage or physician licensing that create uncertainty about the future of telehealth.

This study and others suggest that it may be a mistake to curb telehealth just when it’s catching on. More studies like the one described here may make the case to insurers, regulatory agencies, healthcare providers, and patients that the future of medical care should rely on more, not less, virtual healthcare, and encourage approaches that overcome barriers to its use.

Last winter, my wife shooed the dog and visiting toddlers away from our poinsettia plants, saying "they’re poisonous, you know."

I did not know. But it turns out that the belief that poinsettias are deadly is widespread. The same could be said for mistletoe and holly. But are their reputations for danger well-deserved? Since these plants are especially popular to brighten up homes or give as gifts during the holidays, I decided to look into it.

The risks of poinsettia

Could a plant so common and so well-liked in the winter holidays also be so dangerous? If it is dangerous, what problems does it cause? Must it be eaten to cause problems, or is it harmful to just be nearby? And if it’s not dangerous, why does the myth live on?

The answers to these questions are not easy to find. In fact, the bad reputation may have started in 1919, when an army officer’s child reportedly died after eating part of a poinsettia plant. It is unclear if the plant was responsible, though: many other reports describe mild symptoms, such as nausea or vomiting, but no deaths.

Decades ago, a study in the American Journal of Emergency Medicine analyzed nearly 23,000 cases of people eating poinsettia and found

• no fatalities
• nearly all cases (96%) required no treatment outside the home
• most cases (92%) developed no symptoms at all.

According to one estimate, a 50-pound child would have to eat more than 500 poinsettia leaves to approach a dose that could cause trouble. Similarly, pets may develop gastrointestinal symptoms after eating poinsettia, but these plants pose no major threat to animals.

The risks of mistletoe

The story is much the same for mistletoe. It’s not particularly dangerous, but may cause an upset stomach if eaten. In fact, mistletoe has been used for centuries as a remedy for arthritis, high blood pressure, infertility, and headache. The evidence isn’t high-quality for any of these uses, though.

Interest also centers on this plant’s potential as an anticancer treatment. Some extracts of mistletoe contain chemicals shown to kill cancer cells in the laboratory and to stimulate human immune cells. For example, a substance called alkaloids has similar properties as certain chemotherapy drugs used in the past to fight leukemia and other forms of cancer. However, a two-part 2019 review found that adding mistletoe extracts to conventional cancer treatments did not improve survival or quality of life.

No one suggests it's a good idea to eat this plant, accidentally or otherwise. But eating one to three berries or one or two leaves is unlikely to cause serious illness, according to the authors of a 1986 review of multiple studies. And no significant symptoms or deaths were described in one report of more than 300 cases of eating mistletoe. However, some sources warn that serious problems or even death may occur if enough is ingested. The specific dose required to cause death is unknown but, fortunately, it appears to be so high that consuming enough to be lethal is extremely rare.

The risks of holly

This plant can be dangerous to people and pets. The berries of holly plants are poisonous. If eaten, they may cause crampy abdominal pain, drowsiness, vomiting, and diarrhea. While no one would recommend eating holly, it is unlikely to cause death. And for at least one type of holly, knowing the Latin name would be enough to discourage ingestion: the yaupon holly is also called Ilex vomitoria.

The bottom line

No one should eat poinsettias, mistletoe, and holly, but if small amounts are consumed, they are unlikely to cause serious illness. It seems to me that the dangers of these plants appear to be vastly overestimated.

Perhaps the most dangerous thing about mistletoe and poinsettias is the choking hazard the berries pose for young kids, although that risk is not unique to plants: any small object poses similar risks. Try to keep holiday plants out of the reach of small children and pets. And keep in mind that berries may fall from these plants and wind up on the floor.

If a child or pet eats leaves or berries from these holiday plants, or any other plants, check in with poison control, your pediatrician, or your veterinarian. But unless a particularly large "dose" is consumed, don’t be surprised if the recommendation is to simply watch and wait.

Still concerned even if you know the risks are low? You can always regift holiday plants you receive to friends with no children or pets, or find other ways to decorate your home for the holidays.
