Ultra-processed foods? Just say no

2 metal shopping carts, one filled with ultraprocessed foods and one filling with colorful, healthy fruits and vegetables

Americans love their ultra-processed foods, whether they come as cereal (like Cap’n Crunch, a favorite of mine as a kid), snack foods (like Cheetos), entr’es (like hot dogs), or desserts (like Twinkies). Sure, loading your plate with vegetables, fruits, fish, healthful oils, and grains in a Mediterranean-style diet boosts heart and brain health. But if you also eat some ultra-processed foods, is that bad for your brain health?

What to know about this new study

A new study appears to deliver resounding yes: eating ultra-processed foods is linked to a greater risk of cognitive impairment and strokes.

This well-designed observational study examined data from the REGARDS (REasons for Geographic And Racial Differences in Stroke) project, a longitudinal study of non-Hispanic Black and white Americans ages 45 years and older. Study participants were initially enrolled between 2003 and 2007 and were given a number of questionnaires evaluating health, diet, exercise, body mass index, education, income, alcohol use, mood, and other factors. In addition, tests of memory and language were administered at regular intervals.

To examine the risk of stroke and cognitive impairment, data from 20,243 and 14,175 participants, respectively, were found usable based on the quality of the information from the questionnaires and tests. Approximately one-third of the sample identified as Black and the majority of the remaining two-thirds identified as white.

The results of the study

  • According to the authors’ analysis, increasing the intake of ultra-processed foods by just 10% was associated with a significantly greater risk of cognitive impairment and stroke.
  • Intake of unprocessed or minimally processed foods was associated with a lower risk of cognitive impairment.
  • The effect of ultra-processed foods on stroke risk was greater for individuals who identified as Black compared to individuals who identified as white.

Study participants who reported following a healthy diet (like a Mediterranean, DASH, or MIND diet) and consumed minimal ultra-processed foods appeared to maintain better brain health compared to those who followed similar healthy diets but had more ultra-processed foods.

Why might ultra-processed foods be bad for your brain?

Here are some biologically plausible reasons:

  • UPFs are generally composed of processed carbohydrates that are very quickly broken down into simple sugars, equivalent to eating lots of candy. These sugar loads cause spikes of insulin, which can alter normal brain cell function.
  • Eating ultra-processed foods is associated with a higher risk of metabolic syndrome and obesity, well-established conditions linked to high blood pressure, abnormal blood lipid levels, and type 2 diabetes.
  • There are unhealthy additives in ultra-processed foods to change the texture, color, sweetness, or flavor. These additives disrupt the microbiome in the gut and can lead to gut inflammation that can cause
    • the production of microbiome-produced metabolites that can affect brain function (such as short-chain fatty acids and lipopolysaccharides)
    • leaky gut, allowing toxins and inflammatory molecules to enter the bloodstream and go to the brain
    • altered neurotransmitter function (such as serotonin) that can impact mood and cognition directly
    • increased cortisol levels that mimic being under chronic stress, which can directly impact hippocampal and frontal lobe function, affecting memory and executive function performance, respectively
    • an increased risk for Alzheimer’s, Parkinson’s, and other neurodegenerative diseases due to inflammatory molecules traveling from the gut to the brain.
  • Because ultra-processed foods have poor nutritional value, people will often be hungry shortly after eating them, leading to overeating and its consequences.

The take-home message

Avoid processed foods, which can include chips and other snack foods, industrial breads and pastries, packaged sweets and candy, sugar-sweetened and diet sodas, instant noodles and soups, ready-to-eat meals and frozen dinners, and processed meats such as hot dogs and bologna. Eat unprocessed or minimally processed foods, which — when combined with a healthy Mediterranean menu of foods — include fish, olive oil, avocados, whole fruits and vegetables, nuts and beans, and whole grains.

Health care should improve your health, right?

Illutration of older man in brown and gray top and black pants wobbling on a tightrope against turquoise background; concept is balancing risks

It’s undeniable: modern medicine offers ever-expanding ways to heal and prevent disease. But it’s also true that health care can cause harm. One analysis found that about 6% of health care encounters caused preventable harm, leading to thousands of deaths each year. And it’s not just errors that cause trouble. Highly skilled health care providers can cause harm even when they do everything right.

So, how can you reduce your chances of being harmed? Understanding what you can do to lessen the possibility of harm and what’s beyond your control are good first steps.

Whatever happened to “first do no harm”?

Fortunately, it remains a central tenet of medical care. Yet our health care system is complex and fragmented. Each year new medications are added to an ever-growing list, and people live longer with more chronic medical conditions than happened in the past. So in one sense, the successes of modern medical care may contribute to the high rate of health care–related harm.

These harms are often due to our complicated system of health care rather than one individual’s mistake. Harm due to substandard or negligent care is known as medical malpractice. Both health care providers and health care systems have important roles to play in preventing harm to patients.

Are there harms that cannot be prevented?

An enormous volume of scientific research teaches the best ways to diagnose, treat, and prevent disease. Yet people can react to treatments in completely unpredictable ways.

For example, a common and standard antibiotic treatment (think penicillin) can cause anaphylaxis, a life-threatening allergic reaction. Fortunately this is rare, but unless you or your doctor know to avoid it due to past side effects, there’s always a small chance of a severe reaction.

Often less dramatic — yet also unpreventable — harms are:

  • Medication side effects. Every medicine comes with potential side effects, such as nausea, sleepiness, or rash.
  • Misdiagnosis. Because no one has perfect diagnostic skills, even the most skillful health care provider can be wrong. This can result in unnecessary or delayed treatment.
  • Inaccurate test results. Just as no health care provider is perfect, no test is either. False-positive results (indicating an abnormality when none is present) and false-negative results (normal results when disease is present) are common in medical practice. These results can lead to unnecessary treatment or false reassurance.

Which harms can be prevented?

Preventable harms can be dramatically reduced. They’re often due to mistakes that can be caught and corrected. Frequently, it takes a combination of things to go wrong for harm to occur.

The “Swiss cheese model” is often applied here: imagine you’re a fly trying to travel through several chunks of Swiss cheese. (I know it’s an odd scenario, but stick with me here.) It’s impossible to fly through the cheese unless the holes line up just so.

Frequently in health care, several factors must line up for an error to sneak through — for example, giving a hospitalized patient a medication to which they are allergic. For that to happen, the wrong drug has to get past the prescribing doctor, the computerized ordering system, the hospital pharmacist, the nurse giving the medication, and the patient. That’s a lot of layers, so most often an error like this will be caught.

What can you do to avoid preventable harms?

Where do you fit in? In these three scenarios, here’s what you can do to avoid preventable harms.

The problem: Taking medicines you no longer need or more medicines than necessary.

It might not seem like a big deal to keep taking a medicine if it isn’t causing any problems. But all medicines can cause side effects that you’d do better to avoid if you can safely stop taking it or reduce the dose. Plus, harmful interactions can occur if another medicine is added to your list.

What you can do: Make sure you know why you need to take each of your medicines. Ask the providers who prescribe each medicine if it is still necessary to take it or if the dose can be safely reduced. Reducing a dose may reduce the risk of side effects and the likelihood of a harmful interaction.

The problem: Taking the wrong medicine or the wrong dose.

What you can do: At your doctors’ visits, take notes or bring a friend or family member to help you remember medicine instructions. Ask whether you can record the medication instructions your doctor gives you. Take a photo of the instructions you’re given in case you lose the written version. Double-check details of your medicine list with your pharmacist. And ask questions if you’re unsure about the medicines recommended to you.

The problem: Wrong site surgery.

Despite efforts to make this a “never error,” surgery on the wrong part of the body still happens.

What you can do: Make sure you and your surgeon agree on what part of your body and which side requires surgery. Most surgeons now mark the site with a special pen before surgery and ask you to confirm the site by adding your initials. (The ink doesn’t come off easily with skin cleaners applied prior to surgery).

Some of these tips require time or resources that aren’t available to everyone: you might not be able to bring another person with you to medical visits or have a recording device. But asking questions — and getting answers you understand — should be routine.

Where does malpractice fit in?

When the topic of health care–related harm comes up, malpractice may be the first thing you think about. Yet, the approximately 10,000 malpractice payments made each year in the US likely represent only a small portion of all harm related to health care.

There are several reasons for this, including:

  • Even when negligent or substandard care occurs, it doesn’t always cause major or long-lasting harm that leads to a malpractice claim.
  • Many people who could file malpractice suits elect not to, or may not even realize that they’ve experienced negligent care. Past studies suggest that less than 5% of people experiencing harm related to medical care file malpractice claims.
  • Increasingly, health care providers and health care systems accept responsibility for preventable harm occurring on their watch, and offer compensation rather than waiting for a legal claim to be filed.

The bottom line

It’s an unfortunate reality that some harms due to health care are inevitable. But there are steps you can take to avoid preventable harm and lessen the chances that the person harmed is you.

Prostate cancer: Brachytherapy linked to long-term risk of secondary malignancies

photo of a patient undergoing radiation therapy treatment for cancer; he is seen lying on his back on the bed of a machine with a large white armature hovering above him

When cancer patients are treated with radiation, it’s possible that the therapy itself may cause new tumors to form in the body later. Radiation kills cancer cells by damaging their DNA, but if the treatments cause genetic damage to normal cells near the radiation target, there’s a small risk that these secondary malignancies may arise over time.

Just over 10 years ago, Canadian researchers set out to assess the risk of secondary malignancy among men with prostate cancer who were treated with a type of radiation called brachytherapy. Unlike radiation delivered from sources outside the body, brachytherapy is accomplished by implanting dozens of radioactive pellets, or “seeds,” directly into the tumor site. Those seeds, which are never removed, emit radiation at a dose that declines toward zero over the course of a year.

Brachytherapy has the advantage of convenience. Instead of traveling for repeat sessions of radiation, men need only one treatment, usually given in an outpatient setting. But brachytherapy is also falling out of favor, in part because newer types of external beam radiation deliver high-precision doses with fewer side effects.

Study methodology and results

The Canadian study compared rates of secondary malignancies in the pelvis among men treated either with brachytherapy or with surgery to remove the prostate. All the treatments took place in British Columbia between 1998 and 2000. The brachytherapy group included 2,418 men with an average age of 66, while the surgically-treated group contained 4,015 men whose average age was 62. Within that group, 2,643 men had been treated with surgery alone, and 1,372 men with surgery plus external beam radiation given later.

After median follow-ups of between 5.8 years (brachytherapy) and 6.4 years (surgery), the study team reported in 2014 that there was no difference in rates of secondary malignancies between the groups, or with cancer incidence in the general population.

But that’s no longer the case: In April 2024, the researchers published updated findings. This time, rates of new cancers in the pelvis — including the bladder and rectum — were higher in the brachytherapy group. Specifically, 6.4% of brachytherapy-treated men had secondary malignancies at 15 years of follow-up, increasing to 9.8% after 20 years. By contrast, 3.2% and 4.2% of surgically-treated men developed secondary pelvic malignancies over the same durations. There was no difference in deaths from secondary malignancies between the groups.

The strength of the association with bladder cancer in particular is “similar to that seen with smoking,” wrote the author of an accompanying editorial. Results from the study “should be considered when treating men with localized prostate cancer who have a long life expectancy,” the authors concluded.

Commentary from experts

“I do believe that this study reveals a dark truth about radiation for prostate cancer that has been long suspected,” says Dr. Anthony Zietman, a professor of radiation oncology at Harvard Medical School and Massachusetts General Hospital, and a member of the advisory and editorial board for the Harvard Medical School Guide to Prostate Diseases. “As the decades pass after radiation therapy of any kind — brachytherapy or external beam — the risk for radiation-induced malignancies rises.

“These malignancies are usually in adjacent organs like the bladder and rectum, or within the prostate itself. They may be very curable, and thus the survival rates are the same for radiation or surgically treated patients, but there is little doubt that, for these patients, they represent a ‘sting in the tail’ long after the radiation has been given and forgotten. This data certainly gives us pause when offering radiation to very young men with several decades of life expectancy ahead of them, and it also reminds us of the value of follow-up visits.”

“The fact that second cancers arise in the area where radiation was given is not surprising, but the magnitude of the long-term increases is concerning,” added Dr. Marc Garnick, the Gorman Brothers Professor of Medicine at Harvard Medical School and Beth Israel Deaconess Medical Center, and editor in chief of the Harvard Medical School Guide to Prostate Diseases. “There are other common and troublesome urinary side effects of brachytherapy — independent of second cancers — that patients should fully consider before selecting it as a treatment option. This is especially true given the availability of other convenient and similarly effective prostate cancer therapies.”

Life can be challenging: Build your own resilience plan

Colorful paper cutouts of a thunderstorm at sea with dark clouds, lightening, fish jumping, and a red and white boat bobbing in the waves; concept is resilience

Nantucket, a beautiful, 14-mile-long island off the coast of Massachusetts, has a 40-point resiliency plan to help withstand the buffeting seas surrounding it as climate change takes a toll. Perhaps we can all benefit from creating individual resilience plans to help handle the big and small issues that erode our sense of well-being. But what is resilience and how do you cultivate it?

What is resilience?

Resilience is a psychological response that helps you adapt to life’s difficulties and seek a path forward through challenges.

“It’s a flexible mindset that helps you adapt, think critically, and stay focused on your values and what matters most,” says Luana Marques, an associate professor of psychiatry at Harvard Medical School.

While everyone has the ability to be resilient, your capacity for resilience can take a beating over time from chronic stress, perhaps from financial instability or staying in a job you dislike. The longer you’re in that situation, the harder it becomes to cope with it.

Fortunately, it’s possible to cultivate resilience. To do so, it helps to exercise resiliency skills as often as possible, even for minor stressors. Marques recommends the following strategies.

Shift your thoughts

In stressful situations, try to balance out your thoughts by adopting a broader perspective. “This will help you stop using the emotional part of your brain and start using the thinking part of your brain. For example, if you’re asking for a raise and your brain says you won’t get it, think about the things you’ve done in your job that are worthy of a raise. You’ll slow down the emotional response and shift your mindset from anxious to action,” Marques says.

Approach what you want

“When you’re anxious, stressed, or burned out, you tend to avoid things that make you uncomfortable. That can make you feel stuck,” Marques says. “What you need to do is get out of your comfort zone and take a step toward the thing you want, in spite of fear.”

For example: If you’re afraid of giving a presentation, create a PowerPoint and practice it with colleagues. If you’re having conflict at home, don’t walk away from your partner — schedule time to talk about what’s making you upset.

Align actions with your values

“Stress happens when your actions are not aligned with your values — the things that matter most to you or bring you joy. For example, you might feel stressed if you care most about your family but can’t be there for dinner, or care most about your health but drink a lot,” Marques says.

She suggests that you identify your top three values and make sure your daily actions align with them. If being with family is one of the three, make your time with them a priority — perhaps find a way to join them for a daily meal. If you get joy from a clean house, make daily tidying a priority.

Tips for success

Practice the shift, approach, and align strategies throughout the week. “One trick I use is looking at my calendar on Sunday and checking if my actions for the week are aligned with my values. If they aren’t, I try to change things around,” Marques says.

It’s also important to live as healthy a lifestyle as possible, which will help keep your brain functioning at its best.

Healthy lifestyle habits include:

  • getting seven to nine hours of sleep per night
  • following a healthy diet, such as a Mediterranean-style diet
  • aiming for at least 150 minutes of moderate-intensity activities (such as brisk walking) each week — and adding on strength training at least twice a week
  • if you drink alcohol, limiting yourself to no more than one drink per day for women and two drinks per day for men
  • not smoking
  • staying socially connected, whether in person, by phone or video calls, social media, or even text messages.

Need resilience training?

Even the best athletes have coaches, and you might benefit from resilience training.

Consider taking an online course, such as this one developed by Luana Marques. Or maybe turn to a therapist online or in person for help. Look for someone who specializes in cognitive behavioral therapy, which guides you to redirect negative thoughts to positive or productive ones.

Just don’t put off building resilience. Practicing as you face day-to-day stresses will help you learn skills to help navigate when dark clouds roll in and seas get rough.

Is there a good side to drug side effects?

995e707c-a427-4a53-b9d7-9985fb18e65a

Drug side effects are common, and often quite troublesome.

Major side effects, such as severe or even life-threatening allergic reactions, require immediate treatment and discontinuation of the drug. More minor symptoms may be tolerable when weighed against drug benefits. And sometimes, these go away on their own as the body gets used to the drug.

But there’s another type of side effect you hear much less about: ones that are beneficial. Though uncommon, they’re worth keeping in mind when you’re starting a new medicine.

Aren’t all side effects bad?

The term side effect is usually assumed to be a bad thing. And that’s typically true. But that leaves out the “good” side effects. Relatively little is published on this, so it’s not clear how common they are. But four notable examples include:

  • Minoxidil (Rogaine, Gainextra, other brands). Developed in the 1970s for high blood pressure, this drug also increased hair growth in study subjects. What was initially considered a bothersome side effect eventually became its primary use: topical forms of this drug are commonly used to treat hair loss.
  • Diphenhydramine (Benadryl or generic versions). This common treatment for allergic conditions has the side effect of drowsiness. For adults with allergy issues and trouble sleeping, the sedative effect can be helpful. Regular, long-term use of diphenhydramine is not recommended, as it may increase the risk of dementia.
  • Sildenafil (Viagra or generic versions). Originally developed as a treatment for high blood pressure and angina, it didn’t take long for male users to realize the drug could trigger erections within 30 to 60 minutes. The makers of sildenafil recognized that under the right circumstances, this could be a highly beneficial side effect. In 1998 it was approved as a treatment for erectile dysfunction.
  • Semaglutide (Ozempic, Wegovy, Rybelsus). This drug was developed to treat diabetes, but early users noticed reduced appetite and significant weight loss. Now, several formulations of these related drugs are approved for diabetes and/or weight loss.

In the best study I’ve read on the topic, researchers found more than 450 reports of serendipitous beneficial effects of various drugs since 1991. And that may be an underestimation, since report forms did not specifically ask for or label this type of side effect, according to the study authors.

Silver linings: Repurposing and repackaging drugs

While the discovery of helpful drugs can arise unexpectedly, drug developers are increasingly using a more intentional approach: using side effect profiles to look for new uses.

For example:

  • A drug reported to cause reduced sweating as a side effect may be effective for hyperhidrosis, a condition marked by excessive sweating.
  • Drugs reported to cause low blood pressure as a side effect might be effective treatments for high blood pressure (hypertension).
  • New treatments for breast cancer may include older medicines that have a similar side effect profile as known anti-cancer drugs.

The availability of large side effect registries has made this method of identifying drugs for repurposing a more realistic option. So, even negative side effects can have a silver lining.

Bad side effects and the nocebo effect

While side effects can be positive, most are not. Medication side effects are a common reason people give for not taking prescribed drugs regularly. And adverse reactions to medicines prompt up to 8% of hospital admissions, according to one analysis.

To make matters worse, in some cases the expectation of side effects seems to make them more likely to occur. Called the nocebo effect, it increases the chances of experiencing a negative side effect and seems due, at least in part, to expectations. Contrast this with the placebo effect, where a sugar pill or another inactive treatment can lead to benefit.

The bottom line

Many people avoid taking medications because they fear possible side effects. That’s understandable. But not taking a medication can mean missing out on its benefits. And anticipation or expectation of side effects can increase the chances you’ll have them.

So, while it’s important to be aware of the most common side effects caused by the medicines you take, it’s also important not to overestimate your chances of experiencing them. And remember: there’s always a chance you’ll have a side effect you actually welcome.

5 great tips for sustainable summer living

illustration of a set of rounded-corner app-style icons on the theme of summer, showing ice cream, thermometer, sunglasses, beach ball, cold drink, flip-flops, starfish, and many others

Sustainable living treads lightly on natural resources and follows a rethink, reuse, repurpose mantra to minimize waste.

Big and small wallet-friendly tips can help you save money and befriend our planet this summer, says Dr. Wynne Armand, a primary care physician at Harvard-affiliated Massachusetts General Hospital, and associate director of the Mass General Center for the Environment and Health. Here are five great tips to get you started.

1. Embrace the 5 Rs

Refuse, reduce, reuse, repurpose, and only then recycle is a well-laid out sustainability strategy promoted online by the Cincinnati Recycling and Reuse Hub. Do you really want or need a shiny new object? Where can you share tasks or tools? What could you swap, give away, or buy used? How could you slim down your recycling stream?

Give yourself permission to start here: Nobody is perfect. We all have preferences and sustainability blind spots, fumbles, and “sorry, just no” feelings. Start where you are and add on when you can.

2. Cut down on cooling energy

Summer heat can endanger your health, and paring back on energy use isn’t always possible or wise. Still, it may be possible to:

  • Stay cooler naturally. Pull down shades during daytime hours to block out hot sun. Open windows at night if the temperature cools down, and to capture cross breezes if possible. Dress in loose cotton clothes and wear a shading hat when outdoors. Remember that sun bounces off lighter colors and is soaked up by black or darker colors. Make your own shade by carrying an umbrella on sunny — not just rainy — days. Prepare meals that don’t require cooking or baking, since that saves resources and keeps your home cooler,” advises Dr. Armand.
  • Seek shade and cool spots. If you don’t have air conditioning or you worry about the bills, green, leafy spaces like parks can help cool you down. Cities and towns often open cooling centers, splash pads, and public pools. Public buildings like libraries and malls are available during daytime hours for anyone trying to beat the heat.
  • Turn up the temperature. On air conditioning, that is. If you’re fortunate enough to have air conditioning at home, follow natural cues. When you’re shivering, sweater-seeking, or tucked up under blankets, push the temperature up to save energy and money.

3. Save resources

A sharp eye for energy savings may help pare down bills, too.

  • Electrify. Shrink your carbon footprint and help cut air pollution by using electric grills, mowers, and other landscaping tools. When tools or appliances need to be replaced, consider electric options.
  • Conserve energy. Turn off electrical equipment that is not in use in the office and at home, such as lights, TVs, computers, copiers, and printers. 
  • Go low when demand is high. “During peak electricity demand, ensuring stability of the grid is essential to public health,” says Dr. Armand. “Avoid using appliances like dishwashers, washers, or dryers during periods of high demand. Instead, do these chores — and charge your electric car, if you have one — late at night.” Some energy-hogging appliances have timers to help with this.
  • Sign up for Shave the Peak alerts. Know when to curb your electricity use to avoid times when your local electric grid is relying on nonrenewable, expensive, polluting fossil fuels.

4. Stay heat-aware and hydrated

Saving resources is a worthy goal, but not at the expense of staying safe and healthy when summer temperatures spike.

  • Make plans to stay cool. When summer swelters, having an affordable, personal plan to cool down — especially during heat waves — can be lifesaving.
  • Watch out for signs of dehydration. Drinking plenty of water and eating water-rich foods like lettuce, cucumbers, melon, and citrus fruits can help you stay well hydrated. Water-filling stations for reusable bottles cut down on single-use plastic bottles and help save money at the grocery store.
  • Know how to treat heat rash and more serious heat-related illnesses. The small, itchy red or darkened bumps of heat rash (prickly heat) occur when sweat ducts become blocked or inflamed. This makes it harder for children and adults to cool their bodies down. Generally, too much heat can harm our bodies, particularly if we work outdoors, take certain medicines, or have certain illnesses.

5. Kickstart sharing circles

Sharing circles can help you expand a wardrobe, tool shed, or taste in foods — all while building community.

  • Start local, then consider expanding. Brainstorm with a few friends on what you all might like to share or swap. Think seasonal: gardening tools, outside décor, summer sports (because not everyone needs to own a paddleboard). Local clubs, block associations, or public spaces like libraries and schools may be willing to host community swaps and shares. Some communities have swap sheds and some libraries loan gadgets and even appliances like a portable induction cooktop burner, tech and home-improvement tools, games, and much more.
  • Summer supper club. Perfect for those overloaded with summer harvests from window boxes, community gardens, or a CSA share. Build a theme around what’s fresh, local, and low-cost. Plant-forward menus are good for health and for the planet. Cultural inspiration always helps. And having one person cook — or stressing no-cook recipes — saves resources.
  • Cut your clothing allowance. Tired of your wardrobe? Gather friends for a summer clothes and accessories swap. Be sure to agree on rules: gently-used, carefully washed, no stains, and so on.
  • Hot spots. “Gathering at a friend’s or neighbor’s home for fun games and festivities on hot days is a great way to build community while saving on energy costs for cooling. And rotate for that next hot day!” says Dr. Armand.

How health care leaders can prioritize health equity for the LGBTQIA2+ community

illustration of multiple arms in shades of white, black, and gray raised upward against a dark red background; each arm's hand has a red heart on the palm

Editor's note: Health inequities have long been an issue for people in the LGBTQ+ community. We're pleased to share a post from our colleagues in Corporate Learning at Harvard Medical School focusing on solutions that health care leaders can champion.

Health care business professionals can improve patient outcomes and reduce health inequities by championing the health care needs of the lesbian, gay, bisexual, transgender, queer and/or questioning, intersex, asexual, and two-spirit (LGBTQIA2+) community. These issues are an important priority for health care professionals year-round, not just during Pride Month.

Research shows that the LGBTQIA2+ community faces disproportionate adverse health conditions due to health inequities. It’s important for those working in the health care industry to be aware of the challenges the LGBTQIA2+ community faces to help make systemic changes and improve health outcomes.

The LGBTQIA2+ community — which is less likely to trust the health care system — is a rising part of the population. The 2022 national Gallup survey shows that at least 20% of Gen Z identifies as LGBTQIA2+. This includes our coworkers, customers, and clients, says Dr. Alex Keuroghlian, a psychiatrist at Massachusetts General Hospital and faculty advisor for LGBT and Allies at Harvard Medical School (LAHMS).

“LGBTQIA2+ people experience pervasive stigma and discrimination, as well as numerous adverse social determinants of health, all of which negatively impact health outcomes,” says Dr. Keuroghlian. “Health care professionals, organizations, and governmental agencies need to intentionally provide clinical care and design health systems and policies, in a manner that is culturally responsive and improves health outcomes for LGBTQIA2+ people.”

Due to the politicized nature of these issues, health care providers around the world, including in several U.S. states, face limitations and backlash when providing gender-affirming care. In some places, Dr. Keuroghlian says, “legal restrictions on access to gender-affirming care create challenges for clinicians to deliver this care and for transgender and gender diverse people to safely receive it.”

Everyone in health care — including health care business professionals — can work to improve health outcomes and decrease inequities. “It is critical for all businesses to offer welcoming, inclusive, and affirming work environments and service delivery for LGBTQIA2+ people,” Dr. Keuroghlian says.

Supporting LGBTQIA2+ health begins in the workplace

With thoughtful action, health care business professionals can contribute to greater health equity for these underserved individuals. Some ways to do so include:

1. Take an active interest in better understanding the needs and perspectives of the LGBTQIA2+ community.

Conducting research, including surveys and consumer focus groups, is a good way to help better understand specific health needs and priorities. “This community has historically been excluded from studies and research that would be very helpful in understanding their needs and their challenges,” says Dr. Enrique Caballero, an endocrinologist at Brigham and Women’s Hospital and the faculty director of International Innovation Programs in the HMS Office for External Education. “We need to get to know the population better.”

2. Prioritize inclusive language.

Whether you are involved directly in care delivery or other aspects of health care, pay attention to the words you use — for both customers and employees. Gendered language in job postings, informational or marketing materials, and even casual conversation can be off-putting. That means lost opportunities for organizations and LGBTQIA2+ individuals. Slight shifts in language and conscious efforts like adding pronouns to your email signature speak volumes.

3. Train staff to be community allies.

Gaining awareness of our unconscious biases and making shifts in our everyday language doesn’t happen overnight. Health care industry businesses can help their staff be better allies to the LGBTQIA2+ community by providing access to workshops delivered by community members.

“No one becomes fully competent after one conversation, lecture, or video,” Dr. Caballero says. “It’s a lifelong process in which we all learn how to be more respectful, inclusive, and to embrace diversity.”

4. Support companies and community organizations that focus on LGBTQIA2+ health.

Show, don’t tell. Making financial contributions to organizations already on the ground and working with this population demonstrates that you aren’t just concerned about the bottom line. You are truly dedicated to helping the LGBTQ+ population access good health care.

5. Hire LGBTQIA2+ staff.

The best way to ensure your company is prioritizing health equity is by having a diverse group at the decision-making table. It is crucial to have employees that represent the diversity of your customer base — not only diversity in gender expression and sexuality, but also diversity in race, ethnicity, age, ability, and beyond.

“Part of our obligation is to really open the doors for everybody,” Dr. Caballero says. “Talent is not exclusive to a particular group, and I think that is important to embrace as an organization.”

6. Include LGBTQIA2+ representation in all communications.

Diverse representation is key. Make a pointed effort to include same-sex couples, non-traditional family units, and transgender and non-binary individuals in all kinds of communications, participating in everyday activities.

7. Acknowledge any missteps.

On an institutional level, company acknowledgments can go a long way in rebuilding trust with the LGBTQIA2+ community. Within the organization, it’s valuable to encourage ongoing communication about company culture.

“All organizations should have a system in place for people to provide feedback on how things are going and to report anything that they want to call the leadership team's attention to,” Dr. Caballero says. “Having a system that truly listens to members of the organization — and being sure that follow-up action is taken — is very important.”

8. Make action consistent beyond Pride Month.

Embracing the LGBTQIA2+ community consistently and with commitment all year long “is truly an opportunity for everyone,” Dr. Caballero says. “This is not good just for the members of the community, but for everybody that works in a place that embraces diversity, equity, and inclusion.”

One surprising effect of wildfires: Itchy, irritated skin

Are you finding yourself with itchy, irritated skin that you can’t stop scratching? Or have you wondered why your child’s eczema is suddenly worse and so hard to control? Mounting evidence suggests that wildfires, which are increasing in intensity and frequency, contribute to skin problems, including eczema flares.

What is eczema?

Eczema is a common chronic skin condition that affects about one in 10 people in the US. Its hallmarks are inflamed and dry, itchy patches of skin.

Atopic dermatitis is the most common type of eczema. It can run in families, often beginning in childhood. Typically, in the northern hemisphere, it grows worse during the winter season when the weather is cold and drying. Now some experts are seeing that pattern change. At Massachusetts General Hospital, for example, one dermatologist noted an unusual spike last summer in patients with flare-ups of eczema.

Why is eczema getting worse during summer?

In 2023, Canada experienced more than 6,000 wildfires that burned over 16 million hectares of land — an area larger than the entire state of Georgia. While far away from the devastation, the smoke reached across the US and more than 2,000 miles to Europe. Poor air quality from these distant wildfires caused eye and throat irritation and difficulty breathing.

In Boston, Dr. Arianne Shadi Kourosh, a dermatologist at Massachusetts General Hospital, also began to notice skin symptoms. Normally the dermatology clinics would see fewer than 20 people during a summer month for eczema, including atopic dermatitis. Suddenly that jumped to 160.

Looking back at summer month records from the last four years, her research showed that the number of visits for these skin complaints tracked with the severity of air pollution. These findings are consistent with other research noting an uptick in eczema flares and psoriasis flares associated with wildfire pollution. But why?

Researchers theorize that airborne pollutants might set off a cascade of effects within the body by activating an oxidative stress pathway. This damages the skin barrier and prompts an inflammatory response. This cascade also may play a role in the development of eczema.

What can you do to protect your skin?

Air pollutants in wildfire smoke may harm multiple organs — not just your heart and lungs, but also our skin, it seems. So, when outdoor air quality is bad due to wildfires, limiting your exposure can help reduce health risks. While we can say the same for industrial air pollution, wildfire pollution is likely worse due to its additional toxic particles.

  • Seek help if you’re itching. Check with a dermatologist or your health team if you think wildfire smoke or other forms of air pollution might be affecting your skin.
  • Check local air quality.AirNow.gov shares local, real-time air quality information and activity guidance. When recommended, stay indoors if possible. Shut doors, windows, and any outdoor air intake vents.
  • Protect your skin. When you’re outdoors, wear a mineral-based sunscreen containing zinc or titanium. While most other sunscreens work through a chemical reaction to absorb the ultraviolet (UV) rays that damage skin, zinc and titanium sunscreens help by forming a barrier over skin that reflects off UV rays. The barrier also reduces the amount of pollutant particles getting to the skin to set off the inflammatory cascade. Wearing sunscreen protects against skin cancer, as well.
  • Wash up. After coming back inside, cleansing your skin and applying a hypoallergenic moisturizer will help keep it healthy. If you do have eczema, choose cleansers and moisturizing products recommended by your dermatologist or health care provider.

Shining light on night blindness

A dangerously blurry view of cars, streetlights, headlights through a car window at night; concept is night blindness

Animals renowned for their outstanding night vision include owls, cats, tarsiers (a tiny primate in Southeast Asia) — and even the dung beetle.

But humans? Not so much.

Over time, many people suffer from night blindness, also known as nyctalopia. This condition makes seeing in dim or dark settings difficult because your eyes cannot adjust to changes in brightness or detect light.

What are the dangers for those experiencing night blindness?

Night blindness is especially problematic and dangerous when driving. Your eyes cannot adjust between darkness and the headlights of oncoming vehicles, other cars may appear out of focus, and your depth perception becomes impaired, which makes it difficult to judge distances.

Night blindness also may affect your sight at home by making it hard for your vision to quickly adjust to a dark room after turning off the lights. “This can cause people to bump into furniture or trip and suffer an injury,” says Dr. Isabel Deakins, an optometrist with Harvard-affiliated Massachusetts Eye and Ear.

What happens in the eye to create night blindness?

The ability to see in low-light conditions involves two structures in the eye: the retina and the iris.

The retina, located in the back of the eye, contains two types of light-detecting cells called cones and rods. The cones handle color vision and fine details while the rods manage vision in dim light.

The iris is the colored part of your eye. It contains muscles that widen or narrow the opening of your pupil to adjust how much light can enter your eyes.

If your irises don’t properly react, the pupils can dilate and let in too much light, which causes light sensitivity and makes it hard to see in bright light. Or your pupils may remain too small and not allow in enough light, making it tough to see in low light.

What causes night blindness?

Night blindness is not a disease but a symptom of other conditions. “It’s like having a bruise on your body. Something else causes it,” says Dr. Deakins.

Several conditions can cause night blindness. For instance, medications, such as antidepressants, antihistamines, and antipsychotics, can affect pupil size and how much light enters the eye.

Eye conditions that can cause night blindness include:

  • glaucoma, a disease that damages the eye’s optic nerves and blood vessels
  • cataracts, cloudy areas in the lens that distort or block the passage of light through the lens
  • dry eye syndrome.

However, one issue that raises the risk of night blindness that you can’t control is age. “Our eyes react more slowly to light changes as we age, and vision naturally declines over time,” says Dr. Deakins.  “The number of rods in our eyes diminish, pupils get smaller, and the muscles of the irises weaken.”

What helps if you have night blindness?

If you notice any signs of night blindness, avoid driving and get checked by an eye care specialist like an optometrist or ophthalmologist. An eye exam can determine if your eyeglass prescription needs to be updated.

“Often, a prescription change is enough to reduce glare when driving at night," says Dr. Deakins. “You may even need separate glasses with a stronger eye prescription that you wear only when driving at night.”

Adding an anti-reflective coating to your lens may help to cut down on the glare of the headlights of an oncoming car. However, skip the over-the-counter polarized driving glasses sold at many drug stores. "These may help cut down on glare, but they don't address the causes of night blindness," says Dr. Deakins.

An eye exam also will identify glaucoma or cataracts, which can be treated. Glaucoma treatments include eyedrops, laser treatment, or surgery. Cataracts are corrected with surgery to replace the clouded lens with an artificial one. Your eye care specialist can also help identify dry eye and recommend treatment.

Ask your primary care clinician or a pharmacist if any medications that you take may cause night blindness. If so, it may be possible to adjust the dose or switch to another drug.

Three more ways to make night driving safer

You also can take steps to make night driving safer. For example:

  • Wash the lenses of your glasses regularly. And take them to an optician to buff out minor scratches.
  • Keep both sides of your front and rear car windshields clean so that you can see as clearly as possible.
  • Dim your dashboard lights, which cause glare, and use the night setting on your rearview mirror.

Ever read your medical record? Here’s why you should

Do you ever read the notes written by your doctor or health practitioner during a medical visit? If not, you might want to check them out. Usually, these medical notes are full of helpful insights about your health and reminders of recommendations discussed. And there’s medicalese, of course: hard-to-pronounce illnesses, medications, and technical terms.

But you may be surprised to see incorrect information or unexpected language, tone, or even innuendo. Was your past medical history really that “unremarkable”? Did you actually “deny” drinking alcohol? Did the note describe you as “unreliable”?

Here’s how to decipher unfamiliar lingo, understand some surprising descriptions, and flag any errors you find.

What’s in a medical note?

A standard medical note has several sections. These include

  • a description of current symptoms
  • past medical problems
  • a list of medications taken
  • family medical history
  • social habits such as smoking, drinking alcohol, or drug use
  • details of the physical examination
  • test results
  • a discussion of the big picture, along with recommendations for further evaluation or treatment.

Notes tend to be more complete for a new patient or annual exam. Follow-up notes may not cover all of these points.

What’s potentially confusing about medical notes?

Most medical notes aren’t written using plain language because they aren’t intended primarily for a nonmedical audience. So it’s common to run across:

  • Medical jargon: You had an upset stomach and a fever. Doctors may say “dyspepsia” (upset stomach) and “febrile” (fever).
  • Complicated disease names: Ever heard of “multicentric reticulohistiocytosis” or “progressive multifocal leukoencephalopathy?” These are just two of thousands of examples.
  • Use of common language in uncommon ways: For example, your medical history might be called “unremarkable” and test results called "within normal limits” rather than “normal.”
  • Abbreviations: You might see “VSS” and “RRR,” meaning “vital signs stable” with a pulse that has a “regular rate and rhythm.”

If you’re having trouble deciphering a note or understanding your health issues, tests, and recommendations, check in with your doctor’s office for clarifications. The more you understand about your health and your options for care, the better.

What if a medical note is incorrect?

Minor errors in medical notes are not rare: maybe you had your tonsils removed 30 years ago, not 10 years ago. But there can be more important errors: stating that arthritis in your left knee is severe when it’s actually the right knee that’s severe could lead to having x-rays (or even surgery!) on the wrong side. And not properly recording a family history of cancer or heart disease could mean missing out on timely screening tests or preventive treatments.

In an era of ever-increasing time pressure, use of voice recognition software, electronic record templates, drop-down menus, and ability to copy and paste text, it’s easier than ever for health care providers to make (and perpetuate) errors in the medical record.

If you do see an important error that could affect your health, ask your provider to amend it.

What if the language in a medical note seems offensive?

Numerous studies have highlighted the problem of stigmatizing language in medical notes that can leave people feeling judged or offended. Negative attitudes can affect the quality of our health care and willingness to seek care, and can also widen health disparities. One study linked stigmatizing language to higher rates of medical errors. Of note, this study found higher rates of stigmatizing language and medical error among black patients.

Examples include:

  • Depersonalization: A note might describe a patient as “a drug abusing addict” rather than a person struggling with drug addiction.
  • Insulting or inappropriate descriptors: Notes might contain subjective descriptions that paint the patient in an unflattering light without providing context. For example, the note might say “the patient is unkempt and is drug-seeking” rather than “the patient is experiencing homelessness and has severe, chronic pain.” If a person’s recall of medical events from the past is hazy, they may be called “unreliable.”
  • Dismissiveness: A medical note may suggest a symptom is not real or is exaggerated, rather than taking the complaint seriously.
  • An untrusting tone: Language such as “she claims she never drinks” or “he denies alcohol use” may suggest mistrust by the physician.

Why might this happen, anyway?

How does such language make its way into medical notes? (To be clear, these possible explanations are not justifications.)

  • Tradition and training: Medical trainees, like other learners, tend to follow the lead of their mentors. So if stigmatizing language is used by an instructor, trainees may do the same.
  • Time pressure: With medical documentation (as in most everything else), mistakes are more common if you’re rushing.
  • Bias: Like everyone else, doctors have biases, including ones they aren’t aware of. How we are taught to think about people — by family, by society — can spill over into every area of life, including work.
  • Frustration: Doctors may feel frustrated by patients who don’t follow their recommendations. That frustration can be reflected in their medical notes. For example, a note may say, “As expected, the patient’s blood sugar is high; he is still not checking his blood sugar or following the diet recommended by his nutritionist.”

If the language in a note is confusing or bothersome, ask about it. The Open Notes movement and federal legislation have given most of us much better access to our medical records. This has worthy goals — greater transparency and better communication with people about their medical care — and unintended consequences.

Is changing language in notes that health practitioners once shared mainly with each other a positive consequence? Mostly. Yet some doctors worry that notes will become less specific, accurate, or useful since they may leave out information that might upset a patient.

The bottom line

I encourage you to read your health providers’ notes about your care. If there is a substantial error or something you find confusing or objectionable, ask about it. By the way, a signed medical note cannot usually be revised. However, your doctor can make clarifications or correct mistakes in an addendum at the end of the note.

As more and more patients read their medical notes, it’s likely that health providers will be more conscientious about the language they use. So, wide access to medical notes may improve not only people’s understanding of their health, but also the quality of notes over time.

It's worth remembering that the medical note is not the most important thing that happens during a visit to your doctor. A great note isn’t the same as great care, and vice versa. Still, your medical notes can be a valuable source of health information that differs from all others, including trusted health sites and social media: they’re written by your doctor and they’re all about you.
