The title, of course, is a nod to how by cell count, we are only about 10% human, and the other 90% are assorted microbes.

Dr. Collen starts with the premise that “all diseases begin in the gut” which is perhaps a little bold, but as a general rule of thumb, the gut is, in fairness, implicated in most things—even if not being the cause, it generally plays at least some role in the pathogenesis of disease.

The book talks us through the various ways that our trillions of tiny friends (and some foes) interact with us, from immune-related considerations, to nutrient metabolism, to neurotransmitters, and in some cases, direct mind control, which may sound like a stretch but it has to do with the vagus nerve “gut-brain highway”, and how microbes have evolved to tug on its strings just right. Bearing in mind, most of these microbes have very short life cycles, which means evolution happens for them so much more rapidly than it does for us—something that Dr. Collen, with her PhD in evolutionary biology, has plenty to say about.

There is a practical element too: advice on how to avoid the many illnesses that come with having our various microbiomes (it’s not just the gut!) out of balance, and how to keep everything working together as a team.

The style is quite light pop-science and, once we get past the first chapter (which is about the history of the field), quite a pleasant read as Dr. Collen has an enjoyable and entertaining tone.

Bottom line: if you’d like to understand more about all the things that come together to make us functionally 100% human, then this book is an excellent guide to that.

  • Ending Aging – by Dr. Aubrey de Grey

    We know about how to slow aging. We know about diet, exercise, sleep, intermittent fasting, and other lifestyle tweaks to make. But how much can we turn back the clock, according to science?

    Dr. Aubrey de Grey’s foundational principle is simple: the body is a biological machine, and aging is fundamentally an engineering problem.

    He then outlines the key parts to that problem: the princple ways in which cells (and DNA) get damaged, and what we need to do about that in each case. Car tires get damaged over time; our approach is to replace them within a certain period of time so that they don’t blow out. In the body, it’s a bit similar with cells so that we don’t get cancer, for example.

    The book goes into detail regards each of the seven main ways we accumulate this damage, and highlights avenues of research looking to prevent it, and in at least some cases, the measures already available to so.

    Bottom line: if you want a hard science overview of actual rejuvenation research in biogerontology, this is a book that presents that comprehensively, without assuming prior knowledge.

  • Horse Sedative Use Among Humans Spreads in Deadly Mixture of ‘Tranq’ and Fentanyl

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    TREASURE ISLAND, Fla. — Andrew McClave Jr. loved to lift weights. The 6-foot-4-inch bartender resembled a bodybuilder and once posed for a photo flexing his muscles with former pro wrestler Hulk Hogan.

    “He was extremely dedicated to it,” said his father, Andrew McClave Sr., “to the point where it was almost like he missed his medication if he didn’t go.”

    But the hobby took its toll. According to a police report, a friend told the Treasure Island Police Department that McClave, 36, suffered from back problems and took unprescribed pills to reduce the pain.

    In late 2022, the friend discovered McClave in bed. He had no pulse. A medical examiner determined he had a fatal amount of fentanyl, cocaine, and xylazine, a veterinary tranquilizer used to sedate horses, in his system, an autopsy report said. Heart disease was listed as a contributing factor.

    McClave is among more than 260 people across Florida who died in one year from accidental overdoses involving xylazine, according to a Tampa Bay Times analysis of medical examiner data from 2022, the first year state officials began tracking the substance. Numbers for 2023 haven’t been published.

    The death toll reflects xylazine’s spread into the nation’s illicit drug supply. Federal regulators approved the tranquilizer for animals in the early 1970s and it’s used to sedate horses for procedures like oral exams and colic treatment, said Todd Holbrook, an equine medicine specialist at the University of Florida. Reports of people using xylazine emerged in Philadelphia, then the drug spread south and west.

    What’s not clear is exactly what role the sedative plays in overdose deaths, because the Florida data shows no one fatally overdosed on xylazine alone. The painkiller fentanyl was partly to blame in all but two cases in which the veterinary drug was included as a cause of death, according to the Times analysis. Cocaine or alcohol played roles in the cases in which fentanyl was not involved.

    Fentanyl is generally the “800-pound gorilla,” according to Lewis Nelson, chair of the emergency medicine department at Rutgers New Jersey Medical School, and xylazine may increase the risk of overdose, though not substantially.

    But xylazine appears to complicate the response to opioid overdoses when they do happen and makes it harder to save people. Xylazine can slow breathing to dangerous levels, according to federal health officials, and it doesn’t respond to the overdose reversal drug naloxone, often known by the brand name Narcan. Part of the problem is that many people may not know they are taking the horse tranquilizer when they use other drugs, so they aren’t aware of the additional risks.

    Lawmakers in Tallahassee made xylazine a Schedule 1 drug like heroin or ecstasy in 2016, and several other states including Pennsylvania, Ohio, and West Virginia have taken action to classify it as a scheduled substance, too. But it’s not prohibited at the federal level. Legislation pending in Congress would criminalize illicit xylazine use nationwide.

    The White House in April designated the combination of fentanyl and xylazine, often called “tranq dope,” as an emerging drug threat. A study of 20 states and Washington, D.C., found that overdose deaths attributed to both illicit fentanyl and xylazine exploded from January 2019 to June 2022, jumping from 12 a month to 188.

    “We really need to continue to be proactive,” said Amanda Bonham-Lovett, program director of a syringe exchange in St. Petersburg, “and not wait until this is a bigger issue.”

    ‘A Good Business Model’

    There are few definitive answers about why xylazine use has spread — and its impact on people who consume it.

    The U.S. Drug Enforcement Administration in September said the tranquilizer is entering the country in several ways, including from China and in fentanyl brought across the southwestern border. The Florida attorney general’s office is prosecuting an Orange County drug trafficking case that involves xylazine from a New Jersey supplier.

    Bonham-Lovett, who runs IDEA Exchange Pinellas, the county’s anonymous needle exchange, said some local residents who use drugs are not seeking out xylazine — and don’t know they’re consuming it.

    One theory is that dealers are mixing xylazine into fentanyl because it’s cheap and also affects the brain, Nelson said.

    “It’s conceivable that if you add a psychoactive agent to the fentanyl, you can put less fentanyl in and still get the same kick,” he said. “It’s a good business model.”

    In Florida, men accounted for three-quarters of fatal overdoses involving xylazine, according to the Times analysis. Almost 80% of those who died were white. The median age was 42.

    Counties on Florida’s eastern coast saw the highest death tolls. Duval County topped the list with 46 overdoses. Tampa Bay recorded 19 fatalities.

    Cocaine was also a cause in more than 80 cases, including McClave’s, the Times found. The DEA in 2018 warned of cocaine laced with fentanyl in Florida.

    In McClave’s case, Treasure Island police found what appeared to be marijuana and a small plastic bag with white residue in his room, according to a police report. His family still questions how he took the powerful drugs and is grappling with his death.

    He was an avid fisherman, catching snook and grouper in the Gulf of Mexico, said his sister, Ashley McClave. He dreamed of being a charter boat captain.

    “I feel like I’ve lost everything,” his sister said. “My son won’t be able to learn how to fish from his uncle.”

    Mysterious Wounds

    Another vexing challenge for health officials is the link between chronic xylazine use and open wounds.

    The wounds are showing up across Tampa Bay, needle exchange leaders said. The telltale sign is blackened, crusty tissue, Bonham-Lovett said. Though the injuries may start small — the size of a dime — they can grow and “take over someone’s whole limb,” she said.

    Even those who snort fentanyl, instead of injecting it, can develop them. The phenomenon is unexplained, Nelson said, and is not seen in animals.

    IDEA Exchange Pinellas has recorded at least 10 cases since opening last February, Bonham-Lovett said, and has a successful treatment plan. Staffers wash the wounds with soap and water, then dress them.

    One person required hospitalization partly due to xylazine’s effects, Bonham-Lovett said. A 31-year-old St. Petersburg woman, who asked not to be named due to concerns over her safety and the stigma of drug use, said she was admitted to St. Anthony’s Hospital in 2023. The woman, who said she uses fentanyl daily, had a years-long staph infection resistant to some antibiotics, and a wound recently spread across half her thigh.

    The woman hadn’t heard of xylazine until IDEA Exchange Pinellas told her about the drug. She’s thankful she found out in time to get care.

    “I probably would have lost my leg,” she said.

  • Navigating the health-care system is not easy, but you’re not alone.

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Hello, dear reader!

    This is my first column for Healthy Debate as a Patient Navigator. This column will be devoted to providing patients with information to help them through their journey with the health-care system and answering your questions.

    Here’s a bit about me: I have been a patient partner at The Ottawa Hospital and Ottawa Hospital Research Institute since 2017, and have joined a variety of governance boards that work on patient and caregiver engagement such as the Patient Advisors Network, the Ontario Health East Region Patient and Family Advisory Council and the Equity in Health Systems Lab.

    My journey as a patient partner started much before 2017 though. When I was a teenager, I was diagnosed with a cholesteatoma, a rare and chronic disease that causes the development of fatty tumors in the middle ear. I have had multiple surgeries to try to fix it but will need regular follow-ups to monitor whether the tumor returns. Because of this, I also live with an invisible disability since I have essentially become functionally deaf in one ear and often rely on a hearing aid when I navigate the world.

    Having undergone three surgeries in my adolescent years, it was my experience undergoing surgery for an acute hand and wrist injury following a jet ski accident as an adult that was the catalyst for my decision to become a patient partner. There was an intriguing contrast between how I was cared for at two different health-care institutions, my age being the deciding factor at which hospital I went to (a children’s hospital or an adult one).

    The most memorable example was how, as a teenager or child, you were never left alone before surgery, and nurses and staff took all the time necessary to comfort me and answer my (and my family’s) questions. I also remember how right before putting me to sleep, the whole staff initiated a surgical pause and introduced themselves and explained to me what their role was during my surgery.

    None of that happened as an adult. I was left in a hallway while the operating theater was prepared, anxious and alone with staff walking by not even batting an eye. My questions felt like an annoyance to the care team; as soon as I was wheeled onto the operating room table, the anesthetist quickly put me to sleep. I didn’t even have the time to see who else was there.

    Now don’t get me wrong: I am incredibly appreciative with the quality of care I received, but it was the everyday interactions with the care teams that I felt could be improved. And so, while I was recovering from that surgery, I looked for a way to help other patients and the hospital improve its care. I discovered the hospital’s patient engagement program, applied, and the rest is history!

    Since then, I have worked on a host of patient-centered policy and research projects and fervently advocate that surgical teams adopt a more compassionate approach with patients before and after surgery.

    I’d be happy to talk a bit more about my journey if you ask, but with that out of the way … Welcome to our first patient navigator column about patient engagement.

    Conceptualizing the continuum of Patient Engagement

    In the context of Canadian health care, patient engagement is a multifaceted concept that involves active collaboration between patients, caregivers, health-care providers and researchers. It involves patients and caregivers as active contributors in decision-making processes, health-care services and medical research. Though the concept is not new, the paradigm shift toward patient engagement in Canada started around 2010.

    I like to conceptualize the different levels of patient engagement as a measure of the strength of the relationship between patients and their interlocutors – whether it’s a healthcare provider, administrator or researcher – charted against the duration of the engagement or the scope of input required from the patient.

    Defining different levels of Patient Engagement

    Following the continuum, let’s begin by defining different levels of patient engagement. Bear in mind that these definitions can vary from one organization to another but are useful in generally labelling the level of patient engagement a project has achieved (or wishes to achieve).

    Patient involvement: If the strength of the relationship between patients and their interlocutors is minimal and not time consuming or too onerous, then perhaps it can be categorized as patient involvement. This applies to many instances of transactional engagement.

    Patient advisory/consulting: Right in the middle of our continuum, patients can find themselves engaging in patient advisory or consulting work, where projects are limited in scope and duration or complexity, and the relationship is not as profound as a partnership.

    Patient partnership: The stronger the relationship is between the patient and their interlocutor, and the longer the engagement activity lasts or how much input the patient is providing, the more this situation can be categorized as patient partnership. It is the inverse of patient involvement.

    Examples of the different levels of Patient Engagement

    Let’s pretend you are accompanying a loved one to an appointment to manage a kidney disease, requiring them to undergo dialysis treatment. We’ll use this scenario to exemplify what label could be used to describe the level of engagement.

    Patient involvement: In our case, if your loved one – or you – fills out a satisfaction or feedback survey about your experience in the waiting room and all that needed to be done was to hand it back to the clerk or care team, then, at a basic level, you could likely label this interaction as a form of patient involvement. It can also involve open consultations around a design of a new look and feel for a hospital, or the understandability of a survey or communications product. Interactions with the care team, administrators or researchers are minimal and often transactional.

    Patient advisory/consulting: If your loved one was asked for more detailed information about survey results over the course of a few meetings, this could represent patient advisory/consulting. This could mean that patients meet with program administrators and care providers and share their insights on how things can be improved. It essentially involves patients providing advice to health-care institutions from the perspective of patients, their family members and caregivers.

    Patient advisors or consultants are often appointed by hospitals or academic institutions to offer insights at multiple stages of health-care delivery and research. They can help pilot an initiative based on that feedback or evaluate whether the new solutions are working. Often patient advisors are engaged in smaller-term individual projects and meet with the project team as regularly as required.

    Patient partnership: Going above and beyond patient advisory, if patients have built a trusting relationship with their care team or administrators, they could feel comfortable enough to partner with them and initiate a project of their own. This could be for a project in which they study a different form of treatment to improve patient-centered outcomes (like the time it takes to feel “normal” following a session); it could be working together to identify and remove barriers for other patients that need to access that type of care. These projects are not fulfilled overnight, but require a collaborative, longstanding and trusting relationship between patients and health-care providers, administrators or researchers. It ensures that patients, regardless of severity or chronicity of their illness, can meaningfully contribute their experiences to aid in improving patient care, or develop or implement policies, pilots or research projects from start to finish.

    It is leveraging that lived and living experience to its full extent and having the patient partner involved as an equal voice in the decision-making process for a project – over many months, usually – that the engagement could be labeled a partnership.

    Last words

    The point of this column will be to answer or explore issues or questions related to patient engagement, health communications or even provide some thoughts on how to handle a particular situation.

    I would be happy to collect your questions and feedback at any time, which will help inform future columns. Just email me at max@le-co.ca or connect with me on social media (Linked In, X / Twitter).

  • Hoisin Sauce vs Teriyaki Sauce – Which is Healthier?

    Our Verdict

    When comparing hoisin sauce to teriyaki sauce, we picked the teriyaki sauce.

    Why?

    Neither are great! But spoonful for spoonful, the hoisin sauce has about 5x as much sugar.

    Of course, exact amounts will vary by brand, but the hoisin will invariably be much more sugary than the teriyaki.

    On the flipside, the teriyaki sauce may sometimes have slightly more salt, but they are usually in approximately the same ballpark of saltiness, so this is not a big deciding factor.

    As a general rule of thumb, the first few ingredients will look like this for each, respectively:

    Hoisin:

    • Sugar
    • Water
    • Soybeans

    Teriyaki:

    • Soy sauce (water, soybeans, salt)
    • Rice wine
    • Sugar

    In essence: hoisin is a soy-flavored syrup, while teriyaki is a sweetened soy sauce

    Wondering about that rice wine? The alcohol content is negligible, sufficiently so that teriyaki sauce is not considered alcoholic. For health purposes, it is well under the 0.05% required to be considered alcohol-free.

    For religious purposes, we are not your rabbi or imam, but to our best understanding, teriyaki sauce is generally considered kosher* (the rice wine being made from rice) and halal (the rice wine being de-alcoholized by the processing, making the sauce non-intoxicating).

    *Except during passover

    Sleep: 6 Dimensions And 24 Hours!

    A woman with dark hair, planning ahead for better sleep, against a white background.

    This is Dr. Lisa Matricciani, a sleep specialist from the University of South Australia, where she teaches in the School of Health Sciences.

    What does she want us to know?

    Healthy sleep begins before breakfast

    The perfect bedtime routine is all well and good, but we need to begin much earlier in the day, Dr. Matricciani advises.

    Specifically, moderate to vigorous activity early in the day plays a big part.

    Before breakfast is best, but even midday/afternoon exercise is associated with better sleep at night.

    Plan your time well to sleep—but watch out!

    Dr. Matricciani’s research has also found that while it’s important to plan around getting a good night’s sleep (including planning when this will happen), allocating too much time for sleep results in more restless sleep:

    ❝Allocating more time to sleep was associated with earlier sleep onsets, later sleep offsets, less efficient and more consistent sleep patterns for both children and adults.❞

    (this was very large study involving 1,168 children and 1.360 adults, mostly women)

    What counts as good sleep quality? Is it just efficiency?

    It is not! Although that’s one part of it. You may remember our previous main feature:

    The 6 Dimensions Of Sleep (And Why They Matter)

    Dr. Matricciani agrees:

    ❝Everyone knows that sleep is important. But when we think about sleep, we mainly focus on how many hours of sleep we get, when we should also be looking at our sleep experience as a whole❞

    We Think You Might Like The Sound Of This…

    We’ve written before about the benefits of mindfulness meditation, and how to do it.

    We also reviewed a great book on a related topic:

    This is Your Brain On Music – by Dr. Daniel Levitin

    (yes, that’s the same neuroscientist that we featured as an expert talking about The Five Keys of Aging Healthily)

    But what happens when we combine the two?

    Mantra meditation & music

    Most scientific studies that have been undertaken with regard to meditation tend to focus on mindfulness meditation. It’s easy, effective, and (which makes a difference when it comes to publication bias) is a very safe bet when it comes to funding.

    However, today we’re going to look at mantra meditation, which has a lot in common, neurologically speaking, with music. Indeed, when the two were compared separately in a randomized control trial:

    ❝Daily mantra meditation or classical music listening may be beneficial for cognitive outcomes and quality of life of breast cancer survivors with cancer-related cognitive impairment.

    The cognitive benefits appear to be sustained beyond the initial intervention period.❞

    ~ Dr. Ashley Henneghan et al.

    One possible reason for some of the similar benefits is the vagus nerve—whether intoning a mantra, or humming along to music, the vibrations can stimulate the vagus nerve, which in turn activates the parasympathetic nervous system, resulting in body-wide relaxation:

    The Vagus Nerve (And How You Can Make Use Of It)

    How effective is mantra meditation?

    According to a large recent narrative review, it depends on your goal:

    ❝Based on the studies in the four important areas presented, there is no doubt of a strong connection between mantra meditation and human health.

    Strong evidence has been found that practicing mantra meditation is effective in relieving stress and in coping with hypertension.

    For the other two areas: anxiety and immunity, the evidence is inconclusive or not strong enough to firmly support the claim that the mantra meditation can be used to reduce anxiety or to improve immunity. ❞

    ~ Dr. Dr. Ampere Tseng

    this is a very interesting read if you do have the time!

    How do I practice mantra meditation?

    The definition is broad, but the critical criteria are:

    1. You meditate
    2. …using a mantra

    Lest that seem flippant: those really are the two key points!

    Meditation comes in various forms, and mantra meditation is a form of focussed meditation. While some focussed meditation forms may use a candle or some other focal point, in mantra meditation, the mantra itself provides the focus.

    You may be wondering: what should the mantra be?

    Classic and well-tested mantras include such simple things as the monosyllabic Sanskrit “Om” or “Ham”. We’re a health science newsletter, so we’ll leave esoteric meanings to other publications as they are beyond our scope, but we will say that these result, most naturally, in the humming sound that we mentioned earlier stimulates the vagus nerve.

    But that’s not the only way. Practitioners of religions that have repetitive prayer systems (e.g. anything that uses prayer beads, for example) also provide the basis of focused meditation, using a mantra (in this case, usually a very short oft-repeated prayer phrase).

    How long is needed for benefits?

    Most studies into mantra meditation have used timed sessions of 15–30 minutes, with 20 minutes being a commonly-used session length, once per day. However…

    • Vagus nerve benefits should appear a lot more quickly than that (under 5 minutes) in the case of mantras that cause that vibration we mentioned.
    • Repetitive spoken prayers (or similar repeated short phrases, for the irreligious) will generally effect relaxation in whatever period of time it takes for your brain to be fully focused on what you are doing now, instead of what you were thinking about before. If using counting beads, then you probably already know what number works for you.

    (again, as a health science publication, we cannot comment on any otherworldly benefits, but the worldly benefits seem reason enough to consider these practices for their potential therapeutic effects)

    10almonds tip: for any meditative practice that you want to take approximately a given period of time, we recommend investing in a nice sand timer like this one, as this will not result in a jarring alarm going off!
