Sexual violence occurs throughout the world. A simple definition is any sexual act for which consent is not obtained or freely given, according to the Centers for Disease Control and Prevention (CDC). Rape, sexual coercion, and unwanted sexual contact are a few examples.

While many people heal fully in time, traumatic events like these may contribute to long-lasting health issues such as heart disease, gastrointestinal disorders, and certain mental health conditions. Being aware of these possibilities can help you — and your health care clinicians, if you choose to share with them — identify and respond to health issues promptly.

Our trauma doesn’t have to define us. Knowing how to get proper treatment and support can help people who have experienced sexual violence live fulfilling, healthy lives.

Who is affected by sexual violence?

Statistics vary on different forms of sexual violence. One in four women and one in 26 men in the US report rape or attempted rape during their lifetime, for example.

Anyone can experience sexual violence. But it disproportionately impacts certain groups, such as women, people who are racially or ethnically marginalized or who identify as LGBTQ+, and people with low incomes.

Possible emotional effects of sexual violence: What to know

Most people who experience sexual assault report that it affects their mental health. Depression and anxiety are very common after sexual assault. So is post-traumatic stress disorder (PTSD). A review of multiple studies estimates that 75% of people have symptoms of PTSD within a month of the incident, and about 40% continue to have PTSD one year after the incident.

PTSD symptoms may include

• flashbacks
• distressing or intrusive memories or nightmares
• severe anxiety
• dissociation.

People with PTSD may feel numb, angry, helpless, or overwhelmed. They may also avoid triggers that remind them of the traumatic event, like certain places, smells, or objects.

Remember, your mental health is an important part of your overall health and well-being. Consider finding or asking for a referral for a mental health specialist who specializes in trauma-focused psychotherapy. This might include cognitive processing therapy, exposure-based therapy, or eye movement desensitization and reprocessing (EMDR) therapy.

Possible health effects following sexual violence: What to know

Sexual violence can have immediate health effects, of course, and reaching out to get help is important.

Yet weeks, months, or even years later, some — though not all — people develop health issues related to their trauma. Research suggests sexual violence may increase risk for some chronic health conditions, such as

• heart disease
• diabetes
• high blood pressure
• chronic pain, including pelvic pain
• frequent headaches or migraines
• irritable bowel syndrome
• substance use disorder, including opiate use.

Seeking treatment can support your healing and well-being. Consider talking to your health care provider if you think you may be experiencing any of these symptoms or conditions.

How do I talk to my doctor about my history of sexual assault?

It’s important to feel safe and comfortable with your health provider. Here are four helpful tips to consider when seeking health care:

• Ask about trauma-informed care. While sometimes your choice of provider is limited, you may be able to ask to see a clinician who provides trauma-informed care. Trauma-informed care acknowledges how trauma impacts our health and promotes an individual’s sense of safety and control.
• Share as little or as much as you like. If you’re comfortable, you can tell your clinician you have a history of sexual assault or trauma. It is your choice whether you want to discuss your trauma history with your health professional. If you choose not to, you can still seek care for any health issues related to your sexual assault. This is a confidential part of your medical record, like any other part of your medical history.
• Starting a conversation. If you decide to share, you can start the conversation with one of these examples:
  • “I want you to know I have a history of trauma.”
  • “My trauma continues to affect my health today in [insert ways].”

If the provider asks follow-up questions about your traumatic experience, know that you can provide as little or as much detail as you feel comfortable sharing.

• Medical record confidentiality. Ask if your health care institution provides any extra levels of confidentiality for your medical record. Sometimes, this includes additional access restrictions or passwords to enter your health record. This can be especially important if you have an abusive partner, or another person that you are concerned will try to inappropriately gain access to your medical records.

How can you prepare for a physical exam and talk to a clinician?

• Know that you have choices. A physical exam may help you get care you want or need to address a health issue. Yet sometimes people who have been sexually assaulted find physical exams stressful, difficult, or even traumatic. If your clinician would like to perform a physical exam, know that you can always decline or schedule it for another day or time.
• Consider having a support person present. Sometimes a support person like a good friend may make you more comfortable during your visit or exam. You can also ask the provider to have a second staff member in the room, and request a gender preference.
• Ask the provider to explain things before each step. Before the exam, you can ask the clinician to make sure you understand the steps of the exam. Remember, you can choose to pause or stop the exam at any time.
• Your consent matters. No matter the setting, you always have the right to decide how and when your body is examined and/or touched. All health care providers are held to professional and ethical standards to protect your rights. If a clinician violates this, you have the right to report the incident to the health care employer and/or local law enforcement, and to seek care elsewhere.

A few final thoughts

Sexual violence is never okay under any circumstances. If this has happened to you, know that it is not your fault.

Traumatic experiences like sexual assault can affect the body and mind. They may increase the risk of long-term health issues such as PTSD, depression, substance use disorder, high blood pressure, and chronic pelvic pain. Yet all health conditions related to sexual assault can be effectively treated. And most people who experience trauma heal and go on to live meaningful, fulfilling lives.

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.

Early in the new year, promises to reboot your health typically focus on diet, exercise, and weight loss. And by now you may have begun making changes — or at least plans — to reach those goals. But consider going beyond the big three.

Below are 10 often-overlooked, simple ideas to step up personal health and safety. And most won’t make you break a sweat.

Review your health portals

Your medical information is kept in electronic records. You have access to them through the patient portal associated with your doctor’s office. Set aside time to update portal passwords and peruse recent records of appointments, test results, and notes your doctor took during your visits.

“Many studies have shown that when patients review the notes, they remember far better what went on during interactions with their clinicians, take their medicines more effectively, and pick up on errors — whether it’s an appointment they forgot to make or something their doctor, nurse, or therapist got wrong in documenting an encounter,” says Dr. Tom Delbanco, the John F. Keane & Family Professor of Medicine at Harvard Medical School and cofounder of the OpenNotes initiative, which led shared clinician notes to become the new standard of care.

Doing this can help you become more engaged in your care. “We know from numerous studies that engaged patients who share decisions with those caring for them have better outcomes,” he adds.

Ask about health insurance freebies

Your insurance plan may offer perks that can lead to better health, such as:

• weight loss cessation programs
• quit-smoking programs
• free or reduced gym memberships.

Some insurers even offer breastfeeding counseling and equipment. Call your insurance company or take a close look at their website to find out if there’s anything that would help you.

Get rid of expired medications

Scour your cabinets for expired or unneeded drugs, which pose dangers for you and others. Look for prescription and over-the-counter medications (pills, potions, creams, lotions, droppers, or aerosol cans) as well as supplements (vitamins, minerals, herbs).

Bring your finds to a drug take-back site, such as a drugstore or law enforcement office, or a medical waste collection site such as the local landfill.

As a last resort, toss medications into the trash, but only after mixing them with unappealing substances (such as cat litter or used coffee grounds) and placing the mixture in a sealable plastic bag or container.

Invest in new sneakers

The wrong equipment can sabotage any exercise routine, and for many people the culprit is a worn pair of sneakers. Inspect yours for holes, flattened arch support, and worn treads. New sneakers could motivate you to jazz up your walking or running routine.

For example, if it’s in the budget, buy a new pair of walking shoes with a wide toe box, cushy insoles, good arch support, a sturdy heel counter (the part that goes around your heel), stretchy uppers, and the right length — at least half an inch longer than your longest toe.

Cue up a new health app

There are more than 350,000 health apps geared toward consumer health. They can help you with everything from managing your medications or chronic disease to providing instruction and prompts for improving diet, sleep, or exercise routines, enhancing mental health, easing stress, practicing mindfulness, and more.

Hunt for apps that are free or offer a free trial period for a test drive. Look for good reviews, strong privacy guardrails, apps that don’t collect too much information from you, and those that are popular — with hundreds of thousands or millions of downloads.

Make a schedule for health screenings and visits

Is it time for a colonoscopy, mammogram, hearing test, prostate check, or comprehensive eye exam? Has it been a while since you had a dermatologist examine the skin on your whole body? Should you have a cholesterol test or other blood work — and when is a bone density test helpful?

If you’re not sure, call your primary care provider or any specialists on your health team to get answers.

Four more simple healthy steps

The list of steps you can take this year to benefit your health can be as long as you’d like it to be. Jot down goals any time you think of them.

Here are four solid steps to start you off:

• Take some deep breaths each day. A few minutes of daily slow, deep breathing can help lower your blood pressure and ease stress.
• Get a new pair of sunglasses if your old ones have worn lenses. Make sure the new pair has UV protection (a special coating) to block the sun’s ultraviolet (UV) light, which can cause eye damage and lead to permanent vision loss.
• Make a few lunch dates or phone dates with friends you haven’t seen in a while. Being socially connected wards off loneliness and isolation, which can help lower certain health risks.
• Do a deep cleaning on one room in your home per week. Dust and mold can trigger allergies, asthma, and even illness.

You don’t have to do all of these activities at once. Just put them on your to-do list, along with the larger resolutions you’re working on. Now you’ll have a curated list of goals of varying sizes. The more goals you reach, the better you’ll feel. And that will make for a very healthy year, indeed.

Several evenings a week, as Tyler VanderWeele gathers around the dinner table with his wife and two young kids, the family deliberately pauses during the meal to do something simple but profound. Each member shares several things for which they’re grateful — an act that VanderWeele, co-director of the Initiative on Health, Spirituality, and Religion at the Harvard T.H. Chan School of Public Health, feels changes his family dynamic for the better.

“I do think it makes a difference and can be a very powerful practice,” he says. “Even on those bad days where life seems difficult, that effort is worthwhile.”

Gratitude, health, and longevity

How can the power of gratitude affect our lives? Recent research has pointed to gratitude’s myriad positive health effects, including greater emotional and social well-being, better sleep quality, lower depression risks, and favorable markers of cardiovascular health. Now, new data from the long-term Nurses’ Health Study shows that it may extend lives.

“Gratitude has been one of the most widely studied activities contributing to well-being, but we couldn’t find a single prior study that looked at its effects on mortality and longevity, much to our surprise,” says VanderWeele, co-author of the new research.

What did the study look at?

Published July 2024 in JAMA Psychiatry, the new study drew on data from 49,275 women enrolled in the Nurses’ Health Study. Their average age was 79. In 2016, participants completed a six-item gratitude questionnaire in which they ranked their agreement with statements such as, “I have so much in life to be thankful for,” and “If I had to list everything I felt grateful for, it would be a very long list.”

Four years later, researchers combed through participants’ medical records to determine who had died. There were 4,608 deaths from all causes, as well as from specific causes such as cardiovascular disease, cancer, respiratory diseases, neurodegenerative disease, infection, and injury. Deaths from cardiovascular disease — a top killer of women and men in the United States — were the most common cause.

What did the researchers find?

Participants with gratitude scores in the highest third at the study’s start had a 9% lower risk of dying over the following four years than participants who scored in the bottom third. This did not change after controlling for physical health, economic circumstances, and other aspects of mental health and well-being. Gratitude seemed to help protect participants from every cause of death studied — including cardiovascular disease.

But what does this actually mean?

“A 9% reduction in mortality risk is meaningful, but not huge,” VanderWeele says. “But what’s remarkable about gratitude is that just about anyone can practice it. Anyone can recognize what’s around them and express thanks to others for what’s good in their life.”

While the study couldn’t pinpoint why gratitude is associated with longer life, VanderWeele believes several factors may contribute.

“We know that gratitude makes people feel happier. That in itself has a small effect on mortality risk,” he says. “Practicing gratitude may also make someone a bit more motivated to take care of their health. Maybe they’re more likely to show up for medical appointments or exercise. It may also help with relationships and social support, which we know contribute to health.”

What are the study’s limitations and strengths?

The study was observational. This means it can’t prove that gratitude helps people live longer — only that an association exists. And the particular sample of people analyzed is both the biggest strength and limitation of the research, VanderWeele says. All were older female nurses with high socioeconomic status. The vast majority were white.

“Does the longevity effect extend to men, to those who are younger, and to those with lower socioeconomic resources?” VanderWeele asks. “Those are all open questions.”

On the plus side, he says, the study sample’s large size is one of its biggest strengths. So is the extensive data gathered on potential confounding factors such as participants’ physical health, social characteristics, and other aspects of psychological well-being.

“Between the quality of the data and the size of the sample, we were able to provide reasonable evidence for this modest longevity effect,” he says.

Try this: Six questions to evoke gratitude

Not feeling especially grateful today? You have the power to change that. Asking yourself certain questions can evoke gratitude, such as

• What happened today that was good?
• What am I taking for granted that I can be thankful for?
• Which people in my life am I grateful for?
• What is the last book I read or movie, show, or social media clip I saw that I really appreciated, and why?
• What am I most looking forward to this week, month, and year, and why?
• What is the kindest thing someone has said or done lately?

Similarly, a few simple actions can infuse gratitude into your days. Try VanderWeele’s family routine of regularly expressing gratitude around the dinner table. Another well-known practice — that’s perhaps becoming forgotten in this digital age — is penning thank-you notes.

“I do think writing a thank-you note or gratitude letter gets your mind to dwell on something positive for a longer period, to think more deeply about it, because you have to put it not just in words, but in writing,” VanderWeele says. “It also deepens the relationship and builds that bond.”

One less-recognized but valuable gratitude practice is called a “savoring exercise,” which builds on aspects of mindfulness. All that’s required is “pausing, looking around you, and taking in and enjoying everything that’s good in your current setting,” VanderWeele says. “It’s not a big leap to go from recognizing the good to expressing gratitude for what you have.”

Balance is a skill you don’t think about until you really need it — like when you lose your footing and have to perform an exotic improv dance to keep from hitting the ground. But don’t wait until your sense of balance fails before you give it proper attention. As we age, balance can sharply decline, often with little warning. An exercise program called BEEP can help.

How you keep your balance

While keeping proper balance may seem simple, it involves a complex system with many moveable parts. Whenever you move, your eyes and brain process information about your surroundings. Your feet detect changes in the terrain. Your arms swing to keep you stable, and your lower-body muscles and joints generate rapid power so you can move forward, stop, and change directions.

Unfortunately, this system works less effectively over time. The sensation of our bodies moving through space is not as crisp, and information travels more slowly between the body and brain. Muscles become weaker, and joints lose flexibility.

Any breakdown in your balance system increases your risk of falls, which can cause hip fractures, broken bones, and head injuries.

“Doing more balance exercises and activities can keep your sense of balance in good shape, but you also want to focus on multifaceted movements that work on all the elements of your balance system,” says Dr. Brad Manor, associate director of the Mobility and Falls Translational Research Center with Harvard-affiliated Hebrew SeniorLife.

There are many kinds of balance exercises. Science has not tapped any specific ones as the best; however, some have stood out in many balance-related studies.

For instance, a 2016 study in the journal Gerontology and Geriatric Medicine found that a specific Balance-Enhancing Exercise Program (called BEEP for short) improved balance skills among adults ages 60 to 80. Study participants did better on both solid and uneven surfaces, and increased their walking speed and overall confidence.

Focus on three exercises to improve balance

The BEEP program focused on three exercises: squats, heel and calf raises, and one-legged standing. “These types of exercises increase both the physical and cognition skills needed for better balance,” says Dr. Manor. “Plus, they mimic movements of everyday life.”

He recommends adding these to your regular workouts or doing them daily on their own.

Squats. Stand with your feet shoulder-width apart. Bend your knees and imagine you are sitting down on a stool. Lower down until your thighs are parallel to the ground, or as far as is comfortable. Keep your weight on your heels. Extend your arms forward or place your hands on a chair, counter, or table for stability. Pause for a second or two, then rise back to the starting position. Do this up to 10 times.

Heel and calf raises. Stand with your arms crossed over your chest and lift your heels, so you rise up on your toes. Hold this position for up to 10 seconds, or as long as possible, and then lower your heels. Do this five to 10 times. If you need support, hold on to a door frame, a table, or another sturdy object. You also can place your hands flat on a wall.

One-legged standing. Stand tall and place your hands on your hips or hold on to a table or chair for stability. Then raise one leg, so your foot is about six to 12 inches above the floor. Keep your gaze straight ahead. Hold for 20 to 30 seconds. Repeat on the other leg. Go back and forth three to five times.

You also can perform these exercises with your eyes closed to work on coordination and concentration. Another option is to “distract” yourself by doing unrelated cognitive tasks — count backward, name words that begin with the same letter, or make a mental supermarket list.

“Balance is definitely a use-it-or-lose-it skill,” says Dr. Manor. “But if you work on your balance continuously, you are almost guaranteed to see improvements.”

Roughly one in six men will be diagnosed with prostate cancer at some point in their lives, but these cancers usually aren’t life-threatening. Most newly diagnosed men have Grade Group 1 (GG1) prostate cancer, which can linger for years without causing significant harms.

Prostate cancer is categorized according to how far it has spread and how aggressive it looks under the microscope. Pure GG1 prostate cancer is the least risky form of the disease. It occurs frequently with age, will not metastasize to other parts of the body, and it doesn’t require any immediate treatment.

So, should we even call it cancer? Many experts say no.

Dr. Matthew Cooperberg, who chairs the department of urology at the University of California, San Francisco, says men wouldn’t suffer as much anxiety — and would be less inclined to pursue unneeded therapies — if their doctors stopped referring to low-grade changes in the prostate as cancer. He recently co-chaired a symposium where experts from around the world gathered to discuss the pros and cons of giving GG1 cancer another name.

Treatment discrepancies

GG1 cancer is typically revealed by PSA screening. The goal with screening is to find more aggressive prostate cancer while it’s still curable, yet these efforts often detect GG1 cancer incidentally. Attendees at the symposium agreed that GG1 disease should be managed with active surveillance. With this standard practice, doctors monitor the disease with periodic PSA checks, biopsies, and imaging, and treat the disease only if it shows signs of progression.

But even as medical groups work to promote active surveillance, 40% of men with low-risk prostate cancer in the United States are treated immediately. According to Dr. Cooperberg, that’s in part because the word “cancer” has such a strong emotional impact. “It resonates with people as something that spreads and kills,” he says. “No matter how much we try to get the message out there that GG1 cancer is not an immediate concern, there’s a lot of anxiety associated with a ‘C-word’ diagnosis.”

A consequence is widespread overtreatment, with tens of thousands of men needlessly suffering side effects from surgery or radiation every year. A cancer diagnosis has other harmful consequences: studies reveal negative effects on relationships and employment as well as “someone’s ability to get life insurance,” Dr. Cooperberg says. “It can affect health insurance rates.”

Debate about renaming

Experts at the symposium proposed that GG1 cancer could be referred to instead as acinar neoplasm, which is an abnormal but nonlethal growth in tissue. Skeptics expressed a concern that patients might not stick with active surveillance if they aren’t told they have cancer. But should men be scared into complying with appropriate monitoring? Dr. Cooperberg argues that patients with pure GG1 “should not be burdened with a cancer diagnosis that has zero capacity to harm them.”

Dr. Cooperberg does caution that since biopsies can potentially miss higher-grade cancer elsewhere in the prostate, monitoring the condition with active surveillance is crucial. Moreover, men with a strong family history of cancer, or genetic mutations such as BRCA1 and BRCA2 that put them at a higher risk of aggressive disease, should be followed more closely, he says.

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, agrees. Dr. Garnick emphasized that a name change for GG1 cancer needs to consider a wide spectrum of additional testing. “This decision can’t simply be based on pathology,” he says. “Biopsies only sample a miniscule portion of the prostate gland. Genetic and genomic tests can help us identify some low-risk cancers that might behave in a more aggressive fashion down the road.”

Meanwhile, support for a name change is gaining momentum. “Younger pathologists and urologists are especially likely to think this is a good idea,” Dr. Cooperberg says. “I think the name change is just a matter of time — in my view, we’ll get there eventually.”

Metastatic prostate cancer can progress in different ways. In some men the disease advances rapidly, while other men have slower-growing cancer and a better prognosis. Researchers are developing various tools for predicting how fast prostate cancer might progress. Among the most promising are assays that count circulating tumor cells (CTCs) in blood samples.

Prostate cancer spreads by shedding CTCs into the bloodstream, so higher counts in blood generally reflect worse disease. Sometimes referred to as a liquid biopsy, the CTC assay can help doctors decide if patients should get standard or more aggressive treatment. Just one CTC assay is currently on the market for prostate cancer. Called CellSearch, its use is so far limited to men with late-stage metastatic cancer for whom hormonal therapies are no longer effective.

Using CTC data

Hormonal therapies block testosterone, a hormone that drives prostate tumors to grow. Research shows that high CTC counts predict poorer survival and faster disease progression among patients with metastatic prostate cancer who become resistant to this form of treatment. But new research shows CTC counts are also predictive for early-stage metastatic prostate cancer that still responds to hormonal therapy.

Why is that important? Because the earlier doctors can predict a cancer’s trajectory, the better their ability to select patients who could benefit from more powerful (and potentially more aggressive) drug combinations or a clinical trial. Conversely, men who are older or frail might be treated less aggressively if doctors had better insights into their prognosis.

How the study was done

The investigators collected blood samples from 503 newly-diagnosed patients with hormonally-sensitive metastatic prostate cancer who had enrolled in a clinical trial with experimental hormonal therapies. The team collected baseline samples at trial registration, and then another set of samples after the treatments were no longer working. CTC counts were divided in three categories:

• more than 5 CTCs per 7.5 milliliters (mLs) of blood
• between 1 and 4 CTCs per 7.5 mLs of blood
• zero CTCs per 7.5 mLs of blood.

What the research showed

Results showed that men with higher baseline CTC counts fared worse regardless of which cancer drugs they were taking. Median survival for men with 5 or more CTCs per sample was 27.9 months compared to 56.2 months in men with 1 to 4 CTCs. There weren’t enough patient deaths among those with 0 CTCs to calculate a survival rate.

Similarly, higher CTC counts predicted faster onset of resistance to hormonal therapy: 11.3 months for men in the highest CTC category, compared to 20.7 months and 59 months for men with 1 to 4 and zero CTCs respectively. Importantly, higher CTC counts correlated with measures of prostate cancer severity, including PSA levels, numbers of metastases in bone, and other indicators.

Observations and comments

“This research emphasizes the continued emergence of CTCs in helping to determine outcomes and potentially treatment options for men with metastatic prostate cancer,” said 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.

“Still to be determined is how this type of testing compares with more traditional evaluations of disease advancement, such as x-rays, bone scans, and other types of imaging. Ready access to cancer cells in blood that, in turn, eliminate the need for more invasive biopsy procedures of metastatic deposits will be a welcome addition — especially if future studies show that CTCs inform more precise treatment choices.”

Dr. David Einstein, a medical oncologist specializing in genitourinary cancers at Beth Israel Deaconess Medical Center and assistant professor at Harvard Medical School, agreed with that assessment. “But the Holy Grail is finding predictive biomarkers [like CTCs] that tell you if patients will or will not benefit from particular treatments,” he added. “Answering these types of questions requires randomized clinical trials.”

News flash: What we eat can play a pivotal role in warding off — or treating — disease and enhancing quality of life. You may already believe this, and certainly mounting evidence supports that idea. But on the cluttered shelf of diets claiming top health benefits, which one ranks as the absolute best?

That’s a trick question. In fact, there is no single best diet. A good diet for me may be different from what’s best for you. And for either of us, there may be several good choices with no clear winner.

How can you choose the right diet for you?

When thinking about what diet might be best for you, ask yourself:

• What goals are most important? A goal might be weight loss, improved health, avoiding disease, or something else.
• How do you define “best”? For some people, best means the diet with the highest number of health benefits. For others, it may focus on one specific health benefit, such as lowering cholesterol. Still other people may prefer a diet that delivers the greatest benefit for the lowest cost. Or a diet that is healthy and also easy to stick with.
• What health problems do you have? One diet may have an advantage over another depending on whether you have cancer, cardiovascular disease, diabetes, or none of these.
• Which foods do you like best? Your tastes, culture, and location may shape your dietary preferences, and powerfully affect how likely you are to stick with a specific diet.

Which diets are high in health benefits?

Two very well studied diets demonstrate clear benefit, including lowering risk for heart disease and stroke and reducing high blood pressure: the Mediterranean diet and the DASH diet.

But the portfolio diet may be as good as or better than these plans, at least for combatting cardiovascular disease that contributes to clogged blood vessels, heart attacks, and stroke. What? You’ve never heard of the portfolio diet? You’re not alone.

What is the portfolio diet?

Just as a financial advisor may recommend having a diverse investment portfolio — not just stocks, not just bonds — the portfolio diet follows suit. This largely plant-based diet focuses on diverse foods and food groups proven to lower harmful blood lipids, including LDL (so-called bad cholesterol) and triglycerides.

If you choose to follow this eating pattern, you simply need to learn which foods have a healthy effect on blood lipids and choose them in place of other foods. For some people, this only requires small tweaks to embrace certain foods while downplaying other choices. Or it may call for a bigger upheaval of longtime eating patterns.

Which foods are encouraged in the portfolio diet?

Below are the basics. Eating more of these foods regularly may help lower levels of harmful blood lipids:

• plant-based proteins such as soy, beans, tofu, peas, nuts, and seeds
• high-fiber foods such as oats, barley, berries, apples, and citrus fruit; other examples include bran, berries, okra, and eggplant
• phytosterols, which are a natural compound in plant-based foods such as whole grains, fruits, vegetables, and nuts (other sources are foods fortified with phytosterols or dietary supplements)
• plant-based oils high in monounsaturated fat such as olive oil, avocado oil, safflower oil, and peanut oil.

See? Some of your favorite foods make the cut. That’s a major strength of this approach: the list of recommended foods is long. So, it’s likely that you’re already eating and enjoying some of the recommended foods.

Which foods are not part of the portfolio diet?

It’s worth highlighting foods that are not on this list, such as

• red meat
• highly processed foods
• refined grains and added sugar, which may contribute to chronic inflammation
• butter, cream, and other dairy products high in saturated fat and cholesterol.

What can the portfolio diet do for you?

Researchers have shown that the portfolio diet can improve blood lipids. But can it also lower the risk of heart attack, stroke, and other cardiovascular problems?

Yes, according to a 2023 study published in Circulation. More than nearly 17,000 people kept careful food diaries for 30 years. Those who most closely followed the portfolio diet, compared with those who followed it the least, were more likely to have favorable lipids and inflammation. They were also 14% less likely to have a heart attack, and 14% less likely to have a stroke.

This was true even after accounting for factors that could affect cardiovascular disease risk, such as taking cholesterol-lowering medications, exercise, smoking, or having diabetes or a family history of cardiovascular disease.

Because this was an observational study, it can’t conclusively prove that the portfolio diet, rather than another factor, was responsible for the observed cardiovascular benefits. And we don’t know how much benefit came from reducing or eliminating certain types of foods, rather than from the specific foods eaten.

Does the portfolio diet help people lose weight or deliver other health advantages?

What about the portfolio diet for weight loss? Although some people lose weight on the portfolio diet, it’s not billed as a weight-loss diet. Understanding its potential benefit for other conditions such as obesity, cognitive decline, diabetes, and cancer awaits further research.

Go beyond diet to boost health

Of course, diet is not the only way to improve cardiovascular health and your overall health. You’ll stay healthier by

• not smoking
• getting regular exercise
• maintaining a healthy blood pressure and weight
• preventing diabetes when possible, or getting good medical care to treat it if necessary
• taking prescribed medications such as cholesterol-lowering drugs.

The bottom line

It’s probably best to move past the idea of there being a single best diet. The overall pattern of your diet and your portion sizes are probably more important. For most people, it’s also a good idea to move away from restrictive diets that are nearly impossible to stick with and toward healthier overall eating patterns. The portfolio diet checks both those boxes.

There’s a lot of overlap between the portfolio diet and other healthy diets. So, no one should be suggesting it’s the best diet ever. But if you’re trying to eat healthier, it’s a great place to start.

The holiday season is one of the hardest times of the year to resist salty, fatty, sugary foods. Who doesn’t want to enjoy the special dishes and treats that evoke memories and meaning — especially during the pandemic? Physical distancing and canceled gatherings may make you feel that indulging is a way to pull some joy out of the season.

But stay strong. While it’s okay to have an occasional bite or two of marbled roast beef, buttery mashed potatoes, or chocolate pie, gorging on them frequently can lead to weight gain, and increased blood pressure, blood sugar, and “bad” LDL cholesterol.

Instead, skip the butter, cream, sugar, and salt, and flavor your foods with herbs and spices.

The bounty of nature’s flavor-makers go beyond enticing tastes, scents, and colors. Many herbs and spices contain antioxidants, flavonoids, and other beneficial compounds that may help control blood sugar, mood, and inflammation.

Amp up holiday foods with herbs and spices

Try flavoring your foods with some of the herbs and spices in the list below. Play food chemist and experiment with combinations you haven’t tried before. The more herbs and spices you use, the greater the flavor and health rewards. And that’s a gift you can enjoy all year through.

Allspice: Use in breads, desserts, and cereals; pairs well with savory dishes, such as soups, sauces, grains, and vegetables.

Basil: Slice into salads, appetizers, and side dishes; enjoy in pesto over pasta and in sandwiches.

Cardamom: Good in breads and baked goods, and in Indian dishes, such as curry.

Cilantro: Use to season Mexican, Southwestern, Thai, and Indian foods.

Cinnamon: Stir into fruit compotes, baked desserts, and breads, as well as Middle Eastern savory dishes.

Clove: Good in baked goods and breads, but also pairs with vegetable and bean dishes.

Cumin: Accents Mexican, Indian, and Middle Eastern dishes, as well as stews and chili.

Dill weed: Include in potato dishes, salads, eggs, appetizers, and dips.

Garlic: Add to soups, pastas, marinades, dressings, grains, and vegetables.

Ginger: Great in Asian and Indian sauces, stews, and stir-fries, as well as beverages and baked goods.

Marjoram: Add to stews, soups, potatoes, beans, grains, salads, and sauces.

Mint: Flavors savory dishes, beverages, salads, marinades, and fruits.

Nutmeg: Stir into fruits, baked goods, and vegetable dishes.

Oregano: Delicious in Italian and Mediterranean dishes; it suits tomato, pasta, grain dishes, and salads.

Parsley: Enjoy in soups, pasta dishes, salads, and sauces.

Pepper (black, white, red): Seasons soups, stews, vegetable dishes, grains, pastas, beans, sauces, and salads.

Rosemary: Try it in vegetables, salads, vinaigrettes, and pasta dishes.

Sage: Enhances grains, breads, dressings, soups, and pastas.

Tarragon: Add to sauces, marinades, salads, and bean dishes.

Thyme: Excellent in soups, tomato dishes, salads, and vegetables.

Turmeric: Essential in Indian foods; pairs well with soups, beans, and vegetables.

Looking for gifts to give or donate this year? Climate-conscious gifts come in many guises. They may directly support our environment, for example, or aim to reduce fossil fuel use and electronic, textile, and food waste. Or they might offer enjoyable, creative ways to connect, reuse, and recycle — and possibly even regift.

“Our purchases and choices impact our climate and planet,” notes Dr. Wynne Armand, a physician and associate director of the Massachusetts General Hospital Center for the Environment and Health. Small steps like these do help, she says, even when the complex issues of climate change leading to health-compromising pollution, extreme weather, and a stressed planet feel so large and overwhelming.

“Unquestionably, we need bold, strong leaders to seek policy changes that address these problems at a systems level. But, as individuals we can make a difference through small steps,” says Dr. Armand. “Our choices help drive cultural and market shifts that hopefully push our neighbors, businesses, and policy leaders in the right direction.”

Four climate-conscious principles for gifting

• Channel the 5 Rs. Refuse, reduce, reuse, repurpose, and only then recycle. Say no to excess. Comic sections from print newspapers or beautiful images from last year’s calendars or magazines make great envelopes and gift wrap. If you’re choosing clothes, consider buying upcycled clothing or at resale shops, as appropriate.
• Beware of greenwashing. Eco-consciousness is big business, and the benefits of what you buy may be questionable. If you have a small lawn that needs infrequent maintenance, says Dr. Armand, keeping a trusty (albeit gas-fueled) mower could be a better choice for the planet than buying an electric mower, when factoring in upstream costs of natural resources and the carbon footprint required to manufacture and ship the new — and toss out the not-so-old. (Alternatively, maybe it’s time to replant that lawn with wildflowers and vegetables?)
• Skip what’s not needed. A new backpack crafted from water bottles? Another sweater to add to a closetful? If there’s no apparent need, think twice about purchases.
• Double down on experiences and connection. Think concert tickets, museum passes, or energetic options like rock-climbing gym passes and outdoor skills classes. “Gifts of experience are great, especially for people who already have all they need. If you buy for two or try a skills swap you also get to enjoy that time together,” says Dr. Armand.

25 climate-conscious gifts

Below are 25 suggestions for climate-conscious giving intended to work with many budgets.

Small but mighty climate-conscious gifts

1. Soft, warm sweaters, thick socks, or puffer vests can help people turn down the heat, saving energy resources and money.

2. Rechargeable batteries reduce materials and packaging waste.

3. An electric kettle, induction hot plate, or toaster oven can help limit indoor pollutants from gas stoves.

4. Perfectly Good Food: A Totally Achievable Zero Waste Approach to Home Cooking aims to pare back food waste and is available online.

5. Shop local artisans and craft fairs rather than buying online.

6. Plants brighten any room and help scrub the air: choose easy-care varieties, such as succulents, colorful coleus, and some herbs.

7. Protect the natural world: birds, bees, and other insects could use your help. Consider a small bird feeder that attaches to a window, a bee house, gardening tools, or seeds for a pollinator garden of colorful flowers.

8. Donate to national or worldwide climate or environmental organizations, local green spaces, and local conservation groups.

9. Gift green bonds for companies that support renewable energy — do your research, though, because greenwashing can be an issue.

10. Secret gifter-giftee swaps with large groups save sanity and throttle back waste.

Bigger splurges on climate-conscious gifts

11. When appliances reach the end of useful life, consider replacing gas stoves, water heaters, washers, dryers, and similar items with electric versions.

12. Plan a week of nearby tours and events with friends or family instead of flights and faraway travel.

13. Gift clothes and tools to enjoy the natural world: for example, warm, waterproof clothing and hiking boots, cross-country skis or skates, good binoculars for bird-watching.

14. Composters (or a weekly composting service subscription) recycle food scraps and organic waste into soil-enriching “black gold.”

15. Electric bikes may be a boon if they reduce reliance on vehicles using fossil fuels.

16. Help fund energy-efficient heat pumps or renewable solar energy.

17. Substantial donations and sustaining donor gifts to climate-conscious organizations can help in many ways.

No-cost climate-conscious gifts

18. Offer to gather information on big-ticket items in the big splurges section, including state and federal rebates and 0% loans for heat pumps, energy-efficient furnaces, solar panels, and energy-efficient appliances.

19. Teach a skill one-on-one, such as home repair, skating, chess, training for a mud run, knitting, cooking, orienteering, or gardening, or organize skills swaps with friends.

20. Gift the human power needed to replant portions of a lawn with vegetables or pollinator plants, or make a rain garden (note: automatic download) to help divert storm water.

21. Combine a no-cost reminder of the environmental benefits of no-mow May and leave the leaves campaigns with an offer to help peel back these layers come spring.

22. Friends often want to gift one another — costly generosity that can prompt last-minute candle-buying. As an alternative, gather a small group of friends for a clothing, accessories, and candle swap of new, never-took-the-price-tag-off, nearly new, and well-loved items.

23. Offer a DIY nature or bird walk for two. Try the free Pl@ntnet and Merlin apps if you can’t tell a pin oak from a petunia or a robin from a California condor.

24. If you buy for a ton of people, buy in bulk and figure out how to parcel it out in more sustainable packaging.

25. Make dinner, fudge, or another treat with friends — not completely free, but always a great way to gather your community.
