Catching Alzheimer’s early is key to slowing its progression; however, often, by the time memory loss becomes noticeable, the disease may already have progressed a long way.
Now, researchers at Mass General Brigham have taken a major step toward earlier detection — using the sense of smell.
Alzheimer’s currently affects nearly 7 million Americans, and that number is expected to double to 13.9 million by 2060. An even more shocking statistic is that around 90% of individuals with mild cognitive decline have never received a formal diagnosis.
Diagnosing Alzheimer’s disease in its early stages is challenging when symptoms can be subtle and easily overlooked. There is no single definitive test to distinguish normal age-related forgetfulness from the onset of cognitive decline. Early warning signs often include memory lapses, difficulty finding words, trouble with problem-solving, and changes in mood or behavior.
Studies have shown a connection between a declining sense of smell and dementia. The brain regions responsible for processing smells are often among the first to be impacted by Alzheimer’s, with changes beginning 15-20 years before memory issues surface.
Scientists at Mass General Brigham have now built on this knowledge to develop a simple, digital, at-home smell test called the AROMHA Brain Health Test (ABHT) that could detect Alzheimer’s years before traditional symptoms appear.
The ABHT can evaluate a person’s ability to identify, distinguish, remember, and gauge the strength of different odors to provide clues about brain health and potential early signs of cognitive decline.
“Early detection of cognitive impairment could help us identify people who are at risk of Alzheimer’s disease and intervene years before memory symptoms begin,” said lead study author Mark Albers, a neurologist at Massachusetts General Hospital, in a news release.
The researchers used ABHT on different groups, including cognitively normal individuals, those with subjective cognitive complaints, and those with mild cognitive impairment. Results showed that olfactory performance declined with age, and people with mild cognitive impairment had lower scores in odor identification and discrimination compared to cognitively normal individuals, regardless of age, sex, or education.
“Our results suggest that olfactory testing could be used in clinical research settings in different languages and among older adults to predict neurodegenerative disease and development of clinical symptoms,” Albers added.

Audio Practice: Use Your Hands to Explore Mindful Breathing
By Rose Felix Cratsley
Before starting the practice, find a blank piece of paper and something to draw with, like a marker or pencil.
Step 1: Get Comfortable. Find a comfortable seat, either on the floor or in a chair, and sit tall like a strong tree. You can rest your hands gently on your lap, or place them in front of you. Let your shoulders relax, and your body feel soft. You are in a safe place.
Step 2: Notice Your Hands. Take a moment to notice your hands. How do they feel? Are they warm or cool? Do they feel heavy or light? If you’re feeling nervous or anxious, that’s okay—just notice what’s happening in your hands without judgment. If you feel tense, give your hands a little shake and let the tension fall away.
Step 3: Trace Your Hands. Now, we’re going to trace our hands to create a picture of calm. Place your hand on a piece of paper and trace around it with a pencil or marker. While you trace, feel your fingers, the palm of your hand, and the space between your fingers. Let each stroke of the marker be a reminder that you are safe and in control.
As you trace your hands, know that you’re building something special. Your hands are your own calming tool, always available when you need to relax and feel grounded.
Step 4: Breathe with Your Hands. Now that your hands are traced, we’re going to use them to help us breathe deeply. Each finger will guide us through one breath. We will count from 1 to 10, one number for each finger. With each number, we’ll take a slow, deep breath in and out.
Start with your pinky and breathe in as you count “1.” Feel your chest and belly rise. Now, breathe out as you count “2.” Let the air flow out slowly and feel your body soften. Keep breathing slowly, one number for each finger. As you breathe in, feel your hands fill with calm. As you breathe out, feel your hands and body relax even more.
Step 5: Focus on the Sensation. As you go through each number, pay close attention to how your hands feel. Do they feel warm, soft, or tingly? Notice any changes as you breathe. Imagine your breath flowing through your hands, bringing calmness to every part of your body.
As your mind wanders, simply bring your attention back to your hands and your breath. Take your time, enjoying each breath as an opportunity to slow down and find peace.
Step 6: Feel Grounded and Safe. Take a moment to reflect on how your body feels now. Does your body feel more relaxed? Do your hands feel more calm and steady? Remember, this practice helps us feel grounded—like our feet are firmly planted in the earth, and we are in control of our breath and emotions. Your hands can always be a source of calm. If you ever feel anxious or upset, you can come back to this practice, take a deep breath, and find peace through your hands.
When you feel ready, come back to your day. Take one more deep breath in, and gently breathe out. Slowly bring your awareness back to the space around you. You are calm, centered, and ready to face whatever comes next. You can always return to your calming hands whenever you need them.
Shift Your Focus: How Gratitude Can Help You Navigate Life’s Challenges
Life can be unpredictable, and challenges are an inevitable part of our journey. We all face setbacks, disappointments, and even trauma at some point in our lives. However, it’s how we respond to these challenges that can make all the difference. One powerful tool for navigating life’s challenges is gratitude. Gratitude is more than just saying "thank you" for what we have – it’s a mindset that can shift our focus, change our perspective, and ultimately lead to greater happiness and well-being.
The Power of Gratitude
Gratitude is often overlooked as a strategy for coping with life’s challenges, but it’s a powerful tool that can have a profound impact on our lives. When we focus on what we’re grateful for, it can help us:
Reframe challenges: Instead of seeing challenges as threats or obstacles, we can reframe them as opportunities for growth and learning.
Shift our focus: Gratitude can shift our attention away from what’s lacking or what’s gone wrong and towards what’s still present and positive in our lives.
Cultivate resilience: Practicing gratitude can help us build resilience and bounce back more quickly from setbacks.
Improve relationships: Expressing gratitude towards others can strengthen relationships and foster deeper connections.
How to Practice Gratitude
Practicing gratitude is simple, but it requires intentional effort. Here are a few ways to incorporate gratitude into your daily life:
Keep a gratitude journal: Take a few minutes each day to write down three things you’re grateful for. Reflect on why they’re important to you and how they’ve made a positive impact in your life.
Share your gratitude: Express your gratitude towards others by writing a thank-you note, making a phone call, or sending a text message.
Take time to reflect: Set aside time each day to reflect on your gratitude. This can be as simple as taking a few deep breaths, looking out the window, or practicing a mindful moment.
Overcoming Obstacles to Gratitude
It’s not always easy to practice gratitude, especially when we’re facing difficult circumstances. Here are a few obstacles to overcome:
Feeling stuck: When we’re feeling stuck or stuck in a rut, it can be hard to see the positive. Remember that progress is not a straight line – it’s okay to take a step back or move forward slowly.
Focusing on what’s lacking: It’s easy to get caught up in what’s missing or what’s not working. Try to rebalance your focus by acknowledging what is working and what you’re grateful for.
Comparing yourself to others: Comparing yourself to others can lead to feelings of inadequacy and decreased gratitude. Focus on your own journey and what you’re grateful for, rather than comparing yourself to others.
Conclusion
Gratitude is a powerful tool for navigating life’s challenges. By shifting our focus away from what’s lacking and towards what’s still present and positive in our lives, we can cultivate resilience, build stronger relationships, and find greater happiness and well-being. Practicing gratitude is simple, but it requires intentional effort. By keeping a gratitude journal, sharing our gratitude with others, and taking time to reflect, we can cultivate a more grateful heart and a more fulfilling life.

Mindful Eating 101: Simple Tips to Slim Down and Savor Every Bite
In today’s fast-paced world, it’s easy to get caught up in the hustle and bustle of daily life and overlook one of the most important aspects of our well-being: eating. With the temptation of quick fixes and convenient packaged snacks, it’s no wonder many of us struggle with mindful eating. But what if we could rewire our relationship with food and transform our diets for the better? The good news is that it’s possible, and we’re here to guide you through the process.
Understanding Mindful Eating
Mindful eating is not just about nutrition or dieting; it’s about cultivating a deeper connection with our bodies and the food we put into them. It’s about savoring every bite, listening to our hunger and fullness cues, and honoring our unique relationship with food. By incorporating mindfulness techniques into our daily mealtime routine, we can develop a healthier and more fulfilling relationship with food.
Simple Tips to Slim Down and Savor Every Bite
Savor Your Food: Take small bites, close your eyes, and focus on the flavors, textures, and aromas of each mouthful. Pay attention to the sensations in your mouth, the way the food dissolves or crunches, and the burst of flavor released. By slowing down and truly savoring your food, you’ll not only enjoy it more but also feel more satisfied.
Eat with Your Senses: Engage your senses by paying attention to the colors, shapes, and presentation of your meal. Notice the aroma, the sound of utensils clinking, and the visual appeal of the dish. This mindfulness will help you appreciate the nuances of your food and reduce distractions.
Develop a Pre-Meal Routine: Before each meal, take a few deep breaths, and mentally prepare your body. This can be as simple as taking a few sips of water, doing some quick stretches, or sending a brief gratitude message to your body. This routine will help you shift gears and focus on the present moment.
Honor Your Hunger and Fullness Cues: Tune in to your body’s natural hunger and fullness signals. When you’re hungry, eat slowly, and stop when you’re satisfied. Don’t force yourself to eat when you’re not, and don’t skip meals. By honoring your body’s natural rhythms, you’ll develop a better relationship with food.
Practice Non-Judgment: Banish negative self-talk about food choices, body shape, and weight. Instead, focus on the present moment, the pleasure of eating, and the nourishment you’re receiving. By adopting a non-judgmental attitude, you’ll create a more positive and intuitive approach to eating.
Eat with Others: Share meals with others and engage in relaxing, pleasant conversations. Social eating can be a powerful way to slow down, savor, and enjoy the experience. Bonus points if you can turn off your phone and put away your devices!
Be Kind to Yourself: Remember that setbacks are inevitable, and it’s okay to make mistakes. Don’t beat yourself up over a slipped slip-up or overindulgence. Instead, acknowledge the event, and gently refocus on your mindful eating goals.
How Mindful Eating Can Help with Weight Loss
By incorporating mindful eating techniques into your daily routine, you’ll begin to notice significant changes in your overall well-being and weight management. Here are some key benefits:
Reduced Binge Eating: By eating when you’re hungry, stopping when you’re full, and savoring each bite, you’ll eliminate the need for emotional snacking and reduce the likelihood of overeating.
Increased Satiety: Mindful eating has been linked to reduced inflammation, improved gut health, and increased satisfaction from meals, leading to fewer calories consumed and more sustainable weight loss.
Improved Nutrient Intake: By paying attention to your food choices, you’ll prioritize nutrient-dense options, such as fruits, vegetables, whole grains, and lean protein sources, leading to a more balanced diet.
Enhanced Metabolism: By fueling your body with whole, nutrient-rich foods, you’ll boost your metabolism, supporting a healthy weight and overall well-being.
Conclusion
Mindful eating is not a diet; it’s a journey towards a more intentional relationship with food. By integrating these simple tips into your daily routine, you’ll experience a profound shift in your approach to eating, leading to lasting weight loss, improved health, and a deeper connection with your body. Remember, mindful eating is a skill that can be developed with practice, patience, and self-compassion.
Frequently Asked Questions
Q: I’m not sure where to start. How do I begin?
A: Start by taking small steps, like savoring a single bite or practicing deep breathing exercises during meals. Gradually build upon these habits, and you’ll be well on your way to developing a mindful eating routine.
Q: How do I deal with social eating situations, like parties or holidays?
A: Bring a small, healthy snack to share, and engage in conversations about topics other than food. Remember, it’s okay to politely decline seconds or try a small taste, if you’re not interested in more.
Q: What about snacks? Can I still have them?
A: Absolutely! Snacking can be an opportunity to savor and enjoy, but be mindful of portion sizes and nutritional density. Choose nutrient-dense options, like fruits, nuts, or veggies with hummus.
Q: What if I still struggle with disordered eating or body image issues? How do I rewire my feelings around food?
A: Seek professional help from a registered dietitian, therapist, or health coach, who can guide you through the process. Remember, developing a healthy relationship with food is a journey, and it’s okay to take it one step at a time.
Depending on the reason for your amputation and the state of your limb at the time of surgery, definitive closure of the wound may take place immediately or be delayed until a later date. Wound care involves multiple phases. Here, we will review two phases of the recovery process, talk about the goal of each phase, and discuss your role in managing your surgical wound and the skin of your residual limb.
Phase 1: Pre-Closure of the Residual Limb
The goal of wound management during this phase is to promote healing of the underlying soft tissue and to treat or reduce the risk of infections. In some instances, a drainage tube is inserted to remove fluids and aid in tissue repair. A member of your surgical team will do the dressing changes. Your role in wound management during this stage includes the following:
Notify your nurse if your dressing becomes soiled or you notice any leakage of drainage.
Wash your hands if you come in contact with drainage. Hand soap and hand sanitizers are available in your room.
Make sure everyone who comes in contact with your wound wears gloves and washes his or her hands before and after a dressing change.
In some instances, visitors may need to take special precautions to reduce the likelihood of transmitting an infection to others. In such cases, the nurses will review with you any special precautions for visitors. We are counting on you to see that these precautions are followed.
Exercise caution when moving in bed or getting in and out of bed so that you do not dislodge any dressings or drainage tubes. Notify the nursing staff if dressings become loose or dislodged.
Eat a healthy, well-balanced diet of foods rich in nutrients and vitamins. Tissues cannot heal if they are not provided with the necessary nutrition. Dietary supplements are often provided in addition to your meals to ensure that sufficient calories and protein are available to facilitate the healing process.
Inform members of your rehabilitation team if you experience pain during the care of your wound. By working together, you and your rehab team can establish a medication schedule that will minimize your discomfort during dressing changes.
Injuries that lead to amputation may also result in skeletal injuries to remaining limbs. As a result, you may have skeletal pins and/or an external fixator device applied to maintain bone alignment and promote healing of fractures. If you have one of these devices, your role in taking care of it and your skin will also include the following:
Wash your hands with soap and water.
Mix small amounts of sterile normal saline and hydrogen peroxide in a sterile container.
Saturate a sterile cotton swab applicator in the solution.
Using a circular, rolling motion of the cotton swab, cleanse the pin sites from the insertion site outward.
Avoid going over previously cleaned areas with a used swab.
Gently push down on the skin with the swab to prevent skin from adhering to the pin.
Leave the pin sites open to the air unless drainage is present. If drainage is present, pin sites can be covered with sterile gauze.
Notify a member of your rehabilitation team if you notice swelling, redness, pain, tenderness or a change in drainage from any of your pin sites.
Phase 2: Definitive Closure of the Residual Limb
The goal of wound management during this phase is to prepare your residual limb for prosthetic fitting. Initially, you will have sutures in place to close your surgical wound. These are usually removed in approximately 14-21 days. Your sutures will be covered with petroleum-impregnated gauze, and initially, bulky gauze dressings will be applied to provide additional protection. These dressings are typically changed twice daily, more if necessary. Once your sutures are removed, adhesive strips are applied as the final stage of your wound closure takes place. These strips will fall off naturally in about 5-7 days.
Throughout this stage in your wound-healing process, compression dressings will also be applied to reduce swelling and begin shaping your residual limb for prosthetic fitting. There are two types of compression dressings: rigid and soft. Rigid compression dressings are made from casting material and will be changed as the swelling in your residual limb decreases. Soft compression dressings are initially elastic bandages applied in a specific way to reduce the swelling at the lower portion of your residual limb. These bandages will need to be reapplied several times during the day to maintain proper compression. Members of the rehabilitation team will instruct you in the proper application of these bandages.
Your role in wound management now includes all of the previously listed items plus these additional responsibilities for rigid or soft dressings:
Rigid Compression Dressing
Keep the cast dry. Getting the cast material wet can weaken the cast, and damp padding can irritate your skin.
Avoid getting dirt or powder inside the cast.
Never stick objects inside the cast to scratch your skin. If itching persists, let your nurse know so other measures can be taken.
Notify a member of your rehabilitation team if you feel increased pain or numbness that may be caused by swelling or a cast that is too tight.
Elastic Bandage Compression Dressing
Do not pull at your sutures, even if the skin around the sutures itches.
Notify a member of your rehabilitation team if you notice any tearing or separation of the sutures.
Notify a member of your rehabilitation team if you notice that the skin around the sutures is red or swollen or if you notice any pus draining from the suture area.
Rewrap your residual limb several times during the day (usually at least 4-5 times) to maintain proper compression. This not only reduces the swelling and increases circulation and healing, but also reduces pain.
Obtain new elastic bandages if the ones you are using become soiled or lose elasticity.
Directions for Wrapping with an Elastic Bandage
(Below-knee, below-elbow and above-elbow amputations)
Using a 4-inch-wide elastic bandage, go over the end of the limb, slightly stretching the bandage.
Relax the stretch and secure the bandage by going around the limb once.
Increase the stretch and go to one side of the center.
Decreasing the stretch, go around back. Go up the other side of the center as you increase the stretch again.
Repeat this figure-eight pattern until the end is securely bandaged and then secure the bandage with Velcro or tape. (Do not secure bandages with pins.)
If the length below the knee or elbow is very short, you will need to make a similar figure-eight pattern above and below the joint and then secure the bandage.
(Above-knee amputations)
Use two 6-inch-wide elastic bandages. (Bandages can be sewn together.)
Wrap around the waist twice.
Wrap around the end of the limb.
Wrap back around the waist.
Wrap around the end of the limb.
Wrap around the waist and secure. (This is the anchor for the next bandage.)
Take another 6-inch-wide elastic bandage and, similar to the technique used for below-knee amputations, go over the end of the limb, slightly stretching the bandage.
Relax the stretch and secure the bandage by going around the limb once, then increase the stretch and go to one side of the center.
Decreasing the stretch, go around back, and then go up the other side of the center as you increase the stretch again. Repeat this figure-eight pattern until the end is securely bandaged, making sure to bandage all of the way up into the groin area. Secure the bandage with Velcro or tape. (Do not secure bandages with pins.)
Remember: For best results, you must reapply the elastic bandages whenever they loosen.
Wearing an Elastic Shrinker Sock
Using an elastic shrinker sock is another way to reduce swelling. These shrinker socks can be used alone or in combination with elastic bandages. If the limb is still very sensitive, it will be more comfortable to stretch the shrinker as it is being put on, either by using two pairs of hands or an appropriate-size ring made of a stiff material such as PVC.
Using Hands
With two people using all four of their hands (two can be the patient’s), put all of the fingers down to the bottom of the shrinker, thumbs on the outside, spare material scrunched down, and stretch out until the bottom of the shrinker is completely flat and stretched out.
Place the flat, inside part of the shrinker against the end of the amputated limb.
In one swift motion, keeping the stretch and letting the material slide from between the thumb and fingers, pull the shrinker up the limb.
There should be no gap between the end of the residual limb and the shrinker.
If this is for an above-knee amputee, make sure the long side is around the hip and the short side is all of the way into the groin.
Using a Ring
Make sure the chosen ring will slide easily all of the way to where the shrinker will end on the limb.
Stretch the shrinker over the ring until the end is flat.
Place the flat, inside part of the shrinker over the end of the limb and feed the shrinker up the limb until it is as high as needed.
Remove the ring.
Preparing for Prosthetic Training and Desensitizing Your Residual Limb
At this point in your rehabilitation, there are four techniques you can use to prepare your residual limb for prosthetic training: massage, tapping, desensitization and scar mobilization.
Massage and Tapping
Early massage and tapping of your residual limb will help you develop a tolerance in your residual limb to both touch and pressure. Both of these techniques can be performed through your soft compression dressings and when the soft compression dressing is off. Additionally, these techniques may help decrease your sensation of phantom pain.
Massage
Using one or two hands, massage your residual limb using a soft gentle kneading motion. Initially, be especially cautious when massaging over your sutured area.
Massage the entire residual limb.
Over time and once your sutures are removed, you can increase the pressure to massage the deeper soft tissues and muscles in your residual limb.
This should be done for at least 5 minutes, 3-4 times daily. It can be done more often if it is found to be helpful in reducing phantom pain.
Tapping
Tap your residual limb with your fingertips, being careful not to tap with your fingernails. Gentle tapping over the suture line is generally allowed even before your sutures are removed.
Over time and once your sutures are removed, you can increase to a slapping motion, using one or two hands.
Tapping should be done for 1-2 minutes, 3-4 times daily. It can be done more often if it is found to be helpful in reducing phantom pain.
Desensitization
Desensitization is the process of making your residual limb less sensitive. If you start with a soft material and progress to rougher materials, desensitization can help you increase your tolerance to touch in your residual limb.
This technique is done when you are not wearing your soft compression dressing. It should be done for 2-3 minutes twice daily and is usually done during bathing times.
Initially, start with a cotton ball and gently rub the skin of your residual limb, using a circular motion.
When you are able to tolerate it, progress to a rougher material such as a paper towel.
Finally, advance to a terry cloth towel.
This technique should be done until you can tolerate gentle friction from a terry cloth.
Scar Mobilization
This technique is done to keep the skin and scar tissue on your residual limb loose. Scar adherence to underlying tissue can be a source of pain when using your prosthesis and can also cause blistering. It is best performed when you are not wearing your compression dressing.
Place two fingers over a bony portion of your residual limb.
Press firmly and, keeping your fingertips in the same place on the skin, move your fingers in a circular fashion across the bone for about 1 minute. Continue this procedure on all of the skin and underlying tissue around the bone of your residual limb.
Once your incision is healed, use this procedure over your scar, moving your fingers in a circular fashion to loosen the scar tissue directly.
This technique should be done daily when you bathe.
Inspection of Your Residual Limb
Regular inspection of your residual limb, using a long-handled mirror, will help you identify skin problems early.
Initially, inspections should be done whenever you change your compression dressing. Later on, most amputees find daily inspection sufficient for the early identification of skin problems.
Inspect all areas of your residual limb. Remember to inspect the back and all skin creases and bony areas.
Report any unusual skin problems to a member of your rehabilitation team.
Showering
Permission to resume showering is based on a number of factors and is highly individualized. Your safety and other factors, such as the condition of other wounds and injuries, must all be considered. When you feel ready to resume showering, you should discuss the specifics of your situation with a member of your rehabilitation team. Ask questions about home adaptation, shower chairs and how family members can be trained on any assisted bathing or cleaning care if necessary.
Toilet
Some of the most embarrassing moments can occur while getting to or using the toilet. Discuss your options and limitations with your nurse or ask your peer visitor for advice and alternatives. Try to be patient; your new routine will be comfortable again soon.

Rare disease clinical trials are critical to advancing medicine but come with significant scientific, operational, and regulatory hurdles. Limited patient populations and complex approval pathways demand innovative methodologies, global collaboration, and strategic funding.
This article explores key challenges in rare disease research and strategies for successful trial execution.
1. Funding Rare Disease Research: Financial Innovation and Incentives
The high costs of rare disease trials, driven by small patient cohorts, require financial efficiency. Many governments offer incentives to offset expenses, such as Australia’s 43.5% R&D tax rebate and the U.S. Orphan Drug Act, which provides tax credits, fee waivers, and market exclusivity. However, securing these benefits demands careful planning, especially in multinational trials with varying funding sources.
Sponsors can optimize cash flow by strategically leveraging rebates and tax credits, allowing reinvestment in patient recruitment and advanced analytics while maintaining cost efficiency.
2. Rare Disease Patient Databases: Unlocking Global Access
Patient recruitment remains a major challenge. Registries and advocacy networks help connect researchers with eligible participants, while global patient databases—covering regions like the U.S., Europe, and India—broaden recruitment potential.
Decentralized clinical trial (DCT) models improve accessibility, reducing travel burdens and increasing participation. AI-powered tools further refine patient matching by analyzing clinical data, biomarkers, and genomic profiles across diverse populations.
3. Globalized Teams and Expertise
Rare disease trials require multidisciplinary teams across multiple regions. High-population, low-cost countries like India offer access to genetically diverse patients and cost-effective trial operations. Collaborations with local investigators enhance scalability while maintaining rigorous scientific and ethical standards.
Regulatory expertise is also crucial. Professionals familiar with FDA and EMA pathways help sponsors navigate orphan drug designations, expedited reviews, and global regulatory submissions, ensuring trials stay on track.
Patients with rare diseases are often geographically dispersed, making traditional trial participation difficult. DCT models—incorporating telemedicine, home-based assessments, and mobile health technology—help overcome these barriers.
Countries with strong digital infrastructure, such as India and Southeast Asia, provide cost-efficient DCT implementation, improving patient recruitment and retention while lowering operational expenses.
5. Leveraging Advanced Technologies in Rare Disease Trials
Cutting-edge technologies drive trial efficiency. AI-powered trial design tools optimize protocols and predict recruitment challenges. Real-world data (RWD) and real-world evidence (RWE) supplement traditional clinical data, helping bridge evidence gaps for small patient populations.
Adaptive trial designs further improve success rates by allowing mid-trial modifications based on interim analyses, reducing costs and resource waste.
6. Navigating Regulatory Complexities
Regulatory frameworks for rare diseases present both challenges and opportunities. Programs like the FDA’s Orphan Drug Designation (ODD) and the Rare Pediatric Disease Priority Review Voucher offer incentives but require expert guidance.
Early engagement with regulators ensures trial designs meet data quality and endpoint criteria while incorporating innovative methods such as RWE and surrogate endpoints. Aligning global submissions with FDA and EMA requirements accelerates approvals and minimizes delays.

There is a toxin in lychee fruit that can be harmful, but is it harmful only under certain circumstances?
Lychee fruits have been widely used in many cultures for the folk medicine treatment of everything from farting to testicular swelling. (Arsenic, mercury, and lead are also included in many “traditional” remedies.) Lychees have also apparently “been shown to exhibit numerous health benefits,” but the studies cited include ones like this: “Protective Effect of a Litchi [Lychee]…-Flower-Water-Extract on Cardiovascular Health in a High-Fat/Cholesterol-Dietary Hamsters.” What are we supposed to get from that? We don’t eat lychee flowers…and we aren’t hamsters. Hard to argue with this, though: “Flavor is sweet, fragrant, and delicious,” which is why I love them so much. I then saw this: “A child-killing toxin emerges from shadows. Scientists link mystery deaths…to the consumption of lychees.”
In Vietnam, it’s called “nightmare” encephalitis. There were unexplained outbreaks in children coinciding with lychee harvesting. Children go to bed feeling fine, but they wake up the next morning “seriously ill with brain function derangement and seizures”—if they wake up at all. The same in India, killing up to nearly two out of three kids affected in some places. We’re talking about thousands of kids, so it became “one of the most pressing public health emergencies in India.” It was one of the “three long-standing mystery diseases listed in Wikipedia” and remained a mystery for more than two decades.
All clinical samples were negative for known brain viruses. So, some investigators thought it was caused by an unknown virus, while others thought it might have been due to the pesticides used in the orchards. All we knew was that it seemed to coincide with the lychee harvest. So, might the fruits have attracted fruit bats, then mosquitos could have fed on the infected bats and transferred some new virus from bats to people? Maybe, but why would toddlers and babies be mostly spared? Mosquitoes bite infants, too.
So, were kids swapping spit with the fruit bats by eating half-eaten fruits? “The investigators noted colonies of fruit-eating bats and the tendency of children eating fruits to fall to the ground and suggested the possibility of a bat virus (through saliva contamination on fruits) as a cause of the disease.” Or maybe it was because it was summertime, and they were all just getting heat stroke? Maybe, but why weren’t the pesticides or the heat affecting adults, too?
One of the clues that finally helped investigators tease out the mystery was that the children consistently had low blood sugars—in some cases, fatally low blood sugars. That kind of sounds like “Jamaican vomiting sickness.” Two children “were perfectly well” when they went to bed, but, by “the next morning, they started to vomit and were weak,” then unconscious, then both dead within 48 hours. That was all due to eating unripe ackee fruit, which contains a toxin known as hypoglycin, which prevents our liver from churning out blood sugar all night long to keep our brains alive while we sleep. Ackee is a member of the soapberry family, just like the lychee is. Aha!
As I discuss in my video Lychee Fruit and Hypoglycin: How Many Are Too Many?, Muzaffarpur is a leading lychee producer, and experts at the National Center for Litchi claim they “completely refuted” the lychee link. Nevertheless, independent researchers found it: Lychee fruit contains methylene cyclopropyl-glycine, nearly the same hypoglycin toxin “present in ackee fruits, popular in Jamaica.”
So, in the setting of malnourished children who already have depleted energy stores in their livers “(due to missed meals and poverty-related starvation),” low blood sugar sets in, and, due to the excessive consumption of lychee fruits, the production of new energy is blocked, and the trouble starts. “It is a social tragedy that children have to die in the 21st century due to…hypoglycemia [low blood sugar], which is an easily treatable condition and involves minimal costs.” It’s just as tragic that hungry children are forced to binge on lychees falling on the ground to get a meal. It’s like something out of Grapes of Wrath.
The happy ending, though, is that rather than just focusing on better treatments, local public health workers instead sought to treat the cause by educating people “that no child should go to bed at night without eating a cooked meal and for parents to restrict children eating litchis in the evening to none or very few.” Thankfully, “by applying these recommendations, the disease incidence had been dramatically reduced and death almost completely prevented.” In hindsight, it appears China had already started warning citizens about the dangers of lychees a decade earlier, but word had apparently not gotten around.
What are the implications in the West? In the United States, the Food and Drug Administration tried to protect people against poisoning with this toxin (which is not destroyed by heating) by mandating that canned ackee fruits coming into the country test below a certain level, but there are no such regulations when it comes to importing lychees. “Fortunately, the high cost of these imported fruits and the likelihood that [they] would be eaten in small quantities by well-nourished consumers, suggests there is little reason for concern in the USA.” That’s quite an assumption. Small quantities? You don’t know how I eat lychees. I used to sneak big bags of them—pounds of them—into movie theaters to snack on during the film. How many are too many to eat?
In a series of a few hundred poisoning cases, people reported eating 300 grams to a kilogram of lychee fruits. Each lychee is about 10 grams, so that’s 30 to 100 fruits. Most of the cases were children, though, so we can probably safely say 30 to 100 lychees are too many at one time for kids. What about adults? In a self-experiment, a researcher ate some lychees and measured the hypoglycin levels in his blood and urine, which stayed below the levels seen in the affected children. He ate 5 grams of canned lychee for each kilogram of his body weight, equivalent to about 45 lychee for the average American male, and didn’t suffer any ill symptoms.
What a fascinating story! A lot of research went into just this one topic, but it was all news to me, so I wanted to share it with you.
Obesity has long been associated with an increased risk of health problems, including cancer. However, researchers have recently discovered that a specific body measurement in men could serve as a strong predictor of their cancer risk.
Although Body Mass Index (BMI) serves as a strong indicator of health adversities, a recent study published in The Journal of the National Cancer Institute suggests that waist circumference is an even stronger predictor of cancer risk in men.
The study found that with an additional 4-inch increase in waist size, the risk of cancer rises by 25 percent in men. In comparison, an increase in BMI by 3.7 kg/m² (like going from 24 to 27.7) only raised the risk by 19%. So, even when taking BMI into account, a large waist circumference was still linked to a higher risk of developing obesity-related cancers in men.
This is because unlike BMI, which only measures body size, waist circumference reflects abdominal fat, a key factor linked to increased health risks like insulin resistance, inflammation, and abnormal blood fat levels. This explains why even with the same BMI, differences in fat distribution can lead to varying cancer risks.
However, the study showed that for women, both waist circumference and BMI had similar effects on the risk of obesity-related cancers, but the link was weaker than for men. For example, a 12 cm increase in waist size (like going from 80 cm to 91.8 cm) or a 4.3 increase in BMI (like going from 24 to 28.3) both raised the risk by 13%.
Researchers attribute the difference in cancer risk between men and women to the way fat is distributed in the body. Men tend to accumulate more visceral fat around the abdomen, which is more metabolically active and linked to higher health risks, including cancer. On the other hand, women typically store fat more evenly in peripheral areas like the hips and thighs, where it poses a lower risk.
“Our study provides evidence that waist circumference is a stronger risk factor than BMI for obesity-related cancers in men, but not in women. Additionally, waist circumference appears to provide additional risk information beyond that conveyed by BMI in men,” the researchers wrote in the news release.
“Future research incorporating more precise measures of adiposity, along with comprehensive data on potential confounding factors, could further elucidate the relationship between body fat distribution and cancer risk,” they added.
Health disparities are largely preventable health differences that adversely affect populations who experience greater challenges to optimal health and are closely linked with intergenerational social, economic, and/or environmental disadvantages—primarily based on identification as an individual from a racial and/or ethnic minority group and/or by low socioeconomic status (SES) in society.
Health disparities may be observed in the risks, prevalence, or problems resulting from specific behaviors, as well as the incidence, prevalence, and mortality from conditions, diseases, and/or disorders. Health disparities also can be observed in health care access, quality, and utilization, and within the delivery of clinical care.
Understanding and Addressing Health Disparities
Racial and ethnic minority populations and low SES groups, on average, are facing high rates of most chronic diseases, medical comorbidities, and other health problems. These health disparities may be exacerbated by intersecting factors such as living in an underserved rural location, living with a disability, or identification with a sexual minority group. Intergenerational social disadvantages and discrimination are common threads that link all populations that experience health disparities.
Race and ethnicity are social constructs that should not be applied as a proxy for human genetic variation. The use of race and ethnicity as proxies for human genetic similarity can lead to conflation between social groups and genetic heritage.
SES is also a social construct with various indicators, such as educational attainment, employment, and income. There is a need for integrative and holistic research that provides explanations for the mechanisms by which structural, environmental, biological, and other contextual factors interact in additive and nonadditive ways to contribute to disease etiology and health outcomes.
Addressing health disparities in a meaningful way requires a comprehensive view of how health is maintained, improved, or worsened via modifiable influences, which include but are not limited to:
Factors such as barriers to high-quality health care and adverse environmental and macro-level exposures (physical, chemical, and/or community-related elements) that may impact individual level factors such as:
What Are Metrics of Health and Health Care Disparities?
Health disparities can be identified based on significantly greater or disproportionate morbidity or premature mortality that is preventable on one or more of the following measures:
Incidence and/or prevalence, including earlier onset of disease or higher prevalence of preclinical disease/biomarkers.
Premature or excessive mortality from specific conditions.
Population health disease metrics, such as life expectancy, disability adjusted life years, or health-related quality of life.
Condition-specific symptoms on validated self-reported measures that reflect daily functioning in physical, cognitive, or socio-emotional domains.
Prevalence of short-term and/or long-term preventable complications.
Prevalence of modifiable risks, health risk behaviors, and adverse clinical outcomes.
Inadequate, untimely, or differential access, utilization, or availability of high-quality health care services.
How Do Scientists Select an Appropriate Reference Population/Group in Racial and Ethnic Health Disparities Research*?
The choice of a reference population is important for benchmarking health outcomes and evaluating health disparities. The reference population in U.S. health disparities research has often utilized the racial majority group (i.e., White persons) as the reference group.
The traditional conceptual and analytic practices of using White persons as the reference, and thus, the standard, may perpetuate stereotypes through deficit-based hypotheses and/or interpretations. Moreover, White persons often do not have significantly better outcomes than all other populations.
The selected reference group in health disparities research must be chiefly guided by the scientific questions and potential for generalizable results. Reference group options include, but may not be limited to:
The majority population/group in the geographic context.
The population group with the best health outcome, lowest disease incidence/prevalence, lowest prevalence of risk factors, and/or lowest disease prevalence.
The population group with largest sample size (in the study), which is also referred to as the majority-referenced approach.
Setting absolute targets for outcomes based on societal goals, such as Healthy People 2030 goals, across all demographic groups, rather than focusing on variation across groups.
Using a positive deviance approach, which focuses on people within population groups or subgroups who are thriving or showing positive health-related outcomes despite social, economic, and/or environmental disadvantages, rather than those who are not.
