Are Food Emulsifiers Associated With Increased Cancer Risk?
Food emulsifiers are among the most widespread food additives.
Ultraprocessed foods constitute a significant part of our diet, representing approximately 30% of energy intake in France.
Large epidemiologic studies have already linked diets rich in ultraprocessed products to an increased risk for cardiovascular diseases, diabetes, obesity, and mortality. Possible explanations for this association include the presence of additives, particularly emulsifiers. These additives are intended to improve the texture and shelf life of foods.
Recent experimental studies have shown that emulsifiers alter the gut microbiota and may lead to low-grade inflammation. Dysbiosis and chronic inflammation not only increase the risk for inflammatory bowel diseases but are also implicated in the etiology of several other chronic pathologies and certain extraintestinal cancers.
The NutriNet-Santé study provided extensive information on the dietary habits of > 100,000 French participants. A new analysis was conducted, examining the possible link between the presence of emulsifiers in the diet and cancer occurrence. Data from 92,000 participants (78.8% women) were utilized. They covered an average follow-up of 6.7 years, during which 2604 cancer cases were diagnosed, including 750 breast cancers, 322 prostate cancers, and 207 colorectal cancers.
In this cohort, the risk for cancer increased with a higher presence in the diet of products containing certain emulsifiers widely used in industrial food in Europe: Carrageenans (E407), mono- and diglycerides of fatty acids (E471), pectins (E440), and sodium carbonate (E500).
Notably, the highest consumption of mono- and diglycerides of fatty acids (E471) was associated with a 15% increase in the risk for all types of cancer, a 24% increase in breast cancer risk, and a 46% increase in prostate cancer risk. The highest consumption of carrageenans (E407) was associated with a 28% increase in breast cancer risk.
In an analysis by menopausal status, the risk for breast cancer before menopause was associated with high consumption of diphosphates (E450; 45% increase), pectins (E440; 55% increase), and sodium bicarbonate (E500; 48% increase). No link was found between emulsifier consumption and colorectal cancer risk. While some associations were observed for other emulsifiers, they did not persist in sensitivity analyses.
The European Food Safety Agency recently evaluated the risks of emulsifiers, however, and found no safety issues or need to limit daily consumption of several of them, notably E471.
It is certain that cancer is multifactorial, and a single factor (here, exposure to emulsifiers) will not significantly increase the risk. However, while not essential to human health, emulsifiers are widely prevalent in the global market. Therefore, if causality is established, the increased risk could translate into a significant number of preventable cancers at the population level. Confirmation of this causal link will need to be obtained through experimental and epidemiological studies.

Oxaliplatin in Older Adults With Resected Colorectal Cancer: Is There a Benefit?
This transcript has been edited for clarity.
Our group, the QUASAR Group, made a very significant contribution in terms of trials and knowledge in this field. One of the things that we still need to discuss and think about in our wider community is the impact of adjuvant chemotherapy in older patients.
Colorectal cancer is a disease of the elderly, with the median age of presentation around 72. We know that, at presentation, more than 50% of patients are aged 65 or over and one third of patients are 75 or over. It’s a disease predominantly of the elderly. Are we justified in giving combination chemotherapy with oxaliplatin to high-risk resected colorectal cancer patients?
There’s a very nice report of a meta-analysis by Dottorini and colleagues that came out recently in the Journal of Clinical Oncology. It’s an excellent group. They did their meta-analytical work according to a strict, rational protocol. Their statistical analyses were on point, and they collected data from all the relevant trials.
According to the results of their study, it could be concluded that the addition of oxaliplatin to adjuvant therapy for resected high-risk colorectal cancer in older patients — patients older than 70 — doesn’t result in any statistically significant gain in terms of preventing recurrences or saving lives.
When we did our QUASAR trials, initially we were looking at control vs fluoropyrimidine chemotherapy. Although there was an overall impact on survival of the whole trial group (the 5000 patients in our study), when we looked by decile, there was a significant diminution of benefit even to fluoropyrimidine therapy in our trial in patients aged 70 or above. I think this careful meta-analysis must make us question the use of oxaliplatin in elderly patients.
What could the explanation be? Why could the well-known and described benefits of oxaliplatin, particularly for stage III disease, attenuate in older people? It may be to do with reduction in dose intensity. Older people have more side effects; therefore, the chemotherapy isn’t completed as planned. Although, increasingly these days, we tend only to be giving 3 months of treatment.
Is there something biologically in terms of the biology or the somatic mutational landscape of the tumor in older people? I don’t think so. Certainly, in terms of their capacity, in terms of stem cell reserve to be as resistant to the side effects of chemotherapy as younger people, we know that does attenuate with age.
Food for thought: The majority of patients I see in the clinic for the adjuvant treatment are elderly. The majority are coming these days with high-risk stage II or stage III disease. There is a real question mark about whether we should be using oxaliplatin at all.
Clearly, one would say that we need more trials of chemotherapy in older folk to see if the addition of drugs like oxaliplatin to a fluoropyrimidine backbone really does make a difference. I’ve said many times before that we, the medical community recommending adjuvant treatment, need to have better risk stratifiers. We need to have better prognostic markers. We need to have better indices that would allow us to perhaps consider these combination treatments in a more focused group of patients who may have a higher risk for recurrence.
Have a look at the paper and see what you think. I think it’s well done. It’s certainly given me pause for thought about the treatment that we will offer our elderly patients.
Have a think about it. Let me know if there are any comments that you’d like to make. For the time being, over and out.

Poor Quality of Cancer Content on Social Media
This transcript has been edited for clarity.
I’m delighted to talk about a very interesting topic in this commentary. This is an area that we generally don’t discuss, but it’s one that’s obviously very topical, which includes the question of social media.
The paper I’m referring to is entitled, “More Than a Song and Dance”: Exploration of Patient Perspectives and Educational Quality of Gynecologic Cancer Content on TikTok. The paper was published in Gynecologic Oncology in 2023.
They had a total of 466.7 million views. They looked at 430 of the 500 top posts that were eligible, looked at 11 central themes, did an objective analysis of educational content based on published strategy for looking at this.
What they found, unfortunately but not surprisingly, overall was that the educational quality and reliability were quite poor. They also noticed considerable differences in disparities based on racial background and really emphasized in their analysis not only how common it is for individuals to look at this content on TikTok but also concerns about what it is that the public, patients, and their families are actually seeing.
This, of course, specifically relates to gynecologic cancers, but almost certainly relates to other cancers as well. Clearly, this is a topic that needs to be discussed widely. It’s very complex and very controversial, but when you think about the information that might be provided to our patients and their families going to social media, it’s important that we understand what they’re seeing, what they’re hearing, what they’re viewing, and the impact this might have on their care and outcomes.
I encourage you to read this very interesting paper if you have an interest in this topic. Again, it was recently published in Gynecologic Oncology. I thank you for your attention.

Vaccinated People Have Up to 58% Lower Risk of Long COVID
, a new study from Michigan shows.
The findings were published in the journal Annals of Epidemiology. Researchers analyzed data for 4695 adults in Michigan, looking for people reporting COVID symptoms for more than 30 or more than 90 days after infection. They then looked at whether people had completed a full, initial vaccination series or not. Vaccinated people were 58% less likely than unvaccinated people to have symptoms lasting at least 30 days, and they were 43% less likely to have symptoms for 90 days or more.
The researchers did their study because previous estimates of how much vaccination protects against long COVID have varied widely due to different ways of doing the research, such as mixed definitions of long COVID or including a limited set of people in the unvaccinated comparison group. The researchers wrote that their study offers more certainty because the people who took part in it more widely represent the general population. All of the people in the study had lab test-confirmed infections of SARS-CoV-2 (the virus that causes COVID) between March 2020 and May 2022.
Among vaccinated and unvaccinated people combined, 32% of infected people said they had symptoms for at least 30 days, and nearly 18% said they had symptoms for 90 days or more, according to a summary of the study published by the Center for Infectious Disease Research and Policy at the University of Minnesota. The researchers compared vaccinated and unvaccinated people multiple ways and consistently showed at least a 40% difference in long COVID.
In 2022, 6.9% of US adults self-reported that they had had long COVID, which researchers defined as symptoms for at least 3 months after testing positive or being diagnosed by a doctor, according to a report last week from the CDC. That report also showed that the states with the highest rates of long COVID in 2022 were Alabama, Montana, North Dakota, Oklahoma, Tennessee, West Virginia, and Wyoming. West Virginia had the highest rate of self-reported long COVID, at 10.6% of adults.
People with long COVID may have one or more of about 20 symptoms, including tiredness, fever, and problems that get worse after physical or mental effort. Other long-term signs are respiratory and heart symptoms, thinking problems, digestive issues, joint or muscle pain, rashes, or changes in menstrual cycles. The problems can be so severe that people may qualify for disability status.
About 8 in 10 US adults got the initial round of COVID vaccines, but just 22% of people reported receiving the latest version that became available in the fall of 2023.
The authors of the Michigan study wrote that “COVID-19 vaccination may be an important tool to reduce the burden of long COVID.”

Is It Possible to Change a Slow Metabolism?
Many patients with obesity blame weight gain on their metabolism. The reality is that metabolism can be blamed for weight regain after people try to lose weight! As we age, our metabolism does slow down; sometimes we think it stops working.
What happens to our metabolism when we try to lose weight? Let’s first discuss what metabolism is.
What Is Metabolism?
Metabolism refers to the chemical reactions in the body’s cells that convert food into energy for sustaining life, cellular processes, and as storage for a rainy day.
Total energy expenditure (TEE) is broken down into resting energy expenditure (REE), thermic effect of food (TEF), and nonresting expenditure (NREE) or physical activity, and is made up of: TEE = 60% REE + 10% TEF + 30% NREE.
An elegant study performed by Dr. Rudy Leibel explored the effects of weight loss or weight gain on metabolism in 23 lean and 18 patients with obesity who were placed in a metabolic chamber. Weight loss of 10% or 20% body weight led to a decrease in TEE roughly equal to about 300 kcal/d, and an increase in body weight of 10% caused an increase in TEE of about 500 kcal/d. These changes led to the patient reverting to the prior weight (before weight loss or gain). In other words, Dr. Leibel postulated a feedback mechanism for the effect of fat mass decrease or increase on energy metabolism. The feedback mechanism or signal from fat was subsequently found to be leptin.
In a later study, Dr. Leibel and colleagues investigated the effects of body fat mass change on TEE and found that a 10% reduction in weight caused a decrease of TEE by 21%, comprising a decrease in NREE of 37.5% and a decrease in REE of 11.6%.
Therefore, the biggest change in TEE comes from NREE or exercise energy expenditure. The 35% variance in NEE change was accounted for by a decrease in muscle work efficiency in generating 10 watts or low levels of work such as walking.
In other words, when persons with obesity or lean persons lose weight, the efficiency of muscle at low levels of work increases such that one burns less energy when walking than one normally would. This helps conserve energy and tends to cause the body to go back to the higher weight.
So, How Can One Change Metabolism?
Let’s say one did lose weight and wants to counteract this TEE loss and increased muscle efficiency at low levels of work.
To counteract this effect, one should increase muscle work beyond low level so that more energy is expended. Another way would be to increase muscle mass so that there is more muscle that can do work.
This is exactly how metabolism can be altered or increased. What can be changed most readily, and what we have the most power over in our bodies, is the NREE.
To do this, muscles need anabolic power — the power to heal and build muscle mass. Anabolic power comes from eating healthy protein sources such as lean chicken, fish, beef, and eggs as well as dry beans, tofu, and dairy products.. It seems that older adults (> 60 years) need more protein than younger adults to build muscle mass, due to the body’s natural aging process which leads to sarcopenia. How much more? Studies show between 1.2 and 1.5 g/kg of body weight per day, whereas younger persons need 0.80 g/kg.
Developing sarcopenia with age involves muscle losing the ability to use protein and amino acids to rebuild injured tissue.
Let’s put this in perspective for treating obesity.
Obesity is brought on by the body’s defense of a higher body weight by interaction with the environment of highly processed foods that work on the reward pathway, leading to weight gain and resistance to satiety. Weight loss via diet, exercise, and medications works, but this weight loss is also accompanied by a decrease in TEE.
Weight loss is primarily fat mass loss, but depending on the degree of protein intake and muscle resistance training, 20%-50% of the total weight loss is muscle mass loss. Therefore, higher-protein diets and resistance exercise can be useful in preserving muscle mass and counteracting the decrease in TEE, maintaining energy expenditure. In older patients, an additional factor is the muscle’s lack of ability to use protein as an anabolic agent to protect muscle mass and thus the need for higher protein loads to do this.
All in all, can doctors help patients boost their metabolism, especially as they lose weight and maintain that loss? Yes — through protein intake and resistance exercise training.
Here are some tips to help your patients get cardio and resistance exercise into their routine.
First find out whether your patient prefers a social exercise interaction or solo training. If social, then the gym or classes such as cycling or boot camps at those gyms may work for them, especially if they can go with a friend. If solo is better, than a gym in the home might work. Peloton bikes are expensive but the interaction is all on the website!
A personal trainer may help motivate the patient if they know someone is waiting for them.
Let’s hit the gym!
Another note: There are agents in the obesity treatment pipeline that purport to change body composition while helping patients lose weight. Some of these agents are myostatin antagonists and antibodies that inhibit the activity of myostatin to break down muscle. These agents have been found to build muscle mass, but whether the quality of the muscle mass leads to an increase in muscle strength or functionality remains controversial. The next frontier in obesity treatment will be about decreasing fat mass and increasing muscle mass while making sure that increased muscle mass leads to improved functionality.
In the meantime, aside from new agents on the horizon, the best and healthiest way to keep metabolism on the up and up is to eat healthy lean proteins and exercise. How much exercise? The recommendation is 30-60 minutes of moderate to vigorous physical activity at least 5 days per week; plus 20 minutes of resistance exercise training 2-3 days per week for upper- and lower-extremity and core strength.
Again, let’s hit the gym!

Communicating Bad News to Patients
Communicating bad news to patients is one of the most stressful and challenging clinical tasks for any physician, regardless of his or her specialty. This task is more frequent for physicians caring for oncology patients and can also affect the physician’s emotional state.
The manner in which bad news is communicated plays a significant role in the psychological burden on the patient, and various communication techniques and guidelines have been developed to enable physicians to perform this difficult task effectively.
Revealing bad news in person whenever possible, to address the emotional responses of patients or relatives, is part of the prevailing expert recommendations. However, it has been acknowledged that in certain situations, communicating bad news over the phone is more feasible.
Since the beginning of the COVID-19 pandemic, the disclosure of bad news over the phone has become a necessary substitute for in-person visits and an integral part of clinical practice worldwide. It remains to be clarified what the real psychological impact on patients and their closest relatives is when delivering bad news over the phone compared with delivering it in person.
Right and Wrong Ways
The most popular guideline for communicating bad news is SPIKES, a six-phase protocol with a special application for cancer patients. It is used in various countries (eg, the United States, France, and Germany) as a guide for this sensitive practice and for training in communication skills in this context. The SPIKES acronym refers to the following six recommended steps for delivering bad news:
- Setting: Set up the conversation.
- Perception: Assess the patient’s perception.
- Invitation: Ask the patient what he or she would like to know.
- Knowledge: Provide the patient with knowledge and information, breaking it down into small parts.
- Emotions: Acknowledge and empathetically address the patient’s emotions.
- Strategy and Summary: Summarize and define a medical action plan.
The lesson from SPIKES is that when a person experiences strong emotions, it is difficult to continue discussing anything, and they will struggle to hear anything. Allowing for silence is fundamental. In addition, empathy allows the patient to express his or her feelings and concerns, as well as provide support. The aim is not to argue but to allow the expression of emotions without criticism. However, these recommendations are primarily based on expert opinion and less on empirical evidence, due to the difficulty of studies in assessing patient outcomes in various phases of these protocols.
A recent study analyzed the differences in psychological distress between patients who received bad news over the phone vs those who received it in person. The study was a systematic review and meta-analysis.
The investigators examined 5944 studies, including 11 qualitative analysis studies, nine meta-analyses, and four randomized controlled trials.
In a set of studies ranging from moderate to good quality, no difference in psychological distress was found when bad news was disclosed over the phone compared with in person, regarding anxiety, depression, and posttraumatic stress disorder.
There was no average difference in patient satisfaction levels when bad news was delivered over the phone compared with in person. The risk for dissatisfaction was similar between groups.
Clinical Practice Guidelines
The demand for telemedicine, including the disclosure of bad news, is growing despite the limited knowledge of potential adverse effects. The results of existing studies suggest that the mode of disclosure may play a secondary role, and the manner in which bad news is communicated may be more important.
Therefore, it is paramount to prepare patients or their families for the possibility of receiving bad news well in advance and, during the conversation, to ensure first and foremost that they are in an appropriate environment. The structure and content of the conversation may be relevant, and adhering to dedicated communication strategies can be a wise choice for the physician and the interlocutor.

FDA Authorizes Sleep Apnea App
The Food and Drug Administration has granted De Novo classification to a sleep apnea feature developed by Samsung for use via the Health Monitor app, according to a company press release.
The sleep apnea feature will be available on watches in Samsung’s Galaxy series in the third quarter of 2024, according to the press release.
The sleep apnea feature allows individuals older than 22 years to track their sleep twice for more than 4 hours within a 10-day period. The feature identifies breathing disruptions.
The feature “is expected to help more people proactively detect moderate or severe forms of OSA and, as a result of the detection, seek medical care to reduce the possibility of health-related complications,” according to the company.
Health-related complications associated with poor sleep include increased risk for hypertension, coronary artery disease, heart failure, and stroke, as well as fatigue, decreased mental and emotional well-being, and problems in personal relationships, according to the release.
The feature is not meant for use by individuals with a sleep apnea diagnosis, nor should it replace traditional sleep apnea assessment and diagnosis by qualified clinicians, the company noted.
The feature on the app was approved by Korea’s Ministry of Food and Drug Safety in October 2023.

‘Where Have My Orgasms Gone?’ Sex Medicine and Older Women
“She’s, like, 90 years old. I’m not going to ask her about sex!” says the cringing resident. “She’s older than my grandmother!”
Well, my young friend, our 80- and 90-year-old patients were in their 20s and 30s in the 1960s. You can bet some of them were pretty groovy! A Swedish study of septuagenarians revealed a shift in sexual attitudes: from 5% of 70-year-old women in the 1970s citing sex as a positive aspect of life, to 78% in 2000. Those of us in practice who came of age during the AIDS era and alongside the purity movement of the 1990s can be more sexually reserved than our grandparents. We might need to catch up. In fact, in another study, 82% of 97-year-old female participants felt that being asked about their sexuality in healthcare settings was positive.
Given the high prevalence of dementia among this population, it may be useful to know that positive sexual expression may delay cognitive decline. We also have evidence that sexual satisfaction is important for relational health, which in turn helps predict physical health.
Shed the Dysfunction Mindset
Our medical bias has been that a fulfilling sexual life requires a hard penis and a lubricated vagina. This view of the range of healthy and satisfying sexual expression is lamentably limited. Older adults may have more problems with physiologic arousal in the form of more erectile dysfunction and decreased vaginal lubrication, but these issues may lead to partnerships in which there is less insertive/receiving sexual play and more oral sex, cuddling, kissing, and other forms of partnered sexual play. Older adults may focus less on performance and more on intimacy. In fact, as heterosexual couples encounter these physiologic changes, their sexual behavior may begin to focus more attention to female pleasure. Good news for older women!
As described by Dutch sexuality and aging expert Woet Gianotten, MD, older adults have a lot going for them in their sex lives. Many are retired with more time available, less work stress, greater comfort and familiarity with their partners, and less insecurity about their bodies.
Common Concerns
Many older adults are having satisfying sexual play and are less bothered by changes in their sexual physiology. Still, for those who aren’t happy with their sex lives, clinicians must be ready to address these concerns.
Nancy, an 87-year-old patient whose husband died 5 years ago after 59 years of marriage, has just met someone new. When they are intimate physically, she’s not feeling aroused in the way she recalls, and wonders, Where have my orgasms gone?
A host of physical changes among older women can affect the sexual experience, including the vulvovaginal changes of genitourinary syndrome of menopause (GSM), incontinence, uterine prolapse, diminished sensation, and reduced overall mobility. Although aging is responsible for some of these changes, chronic diseases and medical treatments can play an even larger role.
GSM is a major contributor to sexual pain, genital irritation, and reduced arousal and orgasm. It’s crazy that we don’t ask about and treat GSM. Beyond the sexual impact, the vaginal dryness of GSM can contribute to urinary tract infections, which can lead to sepsis and even death! Vaginal estrogens and other GSM treatments are safe and effective in the vast majority of women. Vaginal moisturizers, vaginal dilators, and increasing genital blood flow also help improve GSM.
Vaginal dilators are used in the management of vaginal stenosis, when the vaginal skin has contracted as a result of GSM or pelvic radiation to treat cancer. Dilators are also used to treat some forms of high-tone pelvic floor dysfunction. For expert guidance and coaching on the use of dilators, seek out sexual medicine specialists and pelvic floor physical therapists. Pelvic floor physical therapy is important in the management of a wide range of sexual concerns, from reduced arousal and orgasm to almost any kind of sexual pain.
For postmenopausal women who are distressed by hypoactive sexual desire disorder, transdermal low-dose testosterone may be considered when other causes of low libido have been ruled out.
Due to changes in nerve fiber sensitivity over time, older age is an ideal phase of life to incorporate higher-intensity vibration and other sexual devices into solo and partner sex. Mobility limitations and joint pain can be addressed with devices designed specifically for this purpose or with the use of pillows and other supports.
As Betty Dodson, a staunch advocate for women’s pleasure until her death in 2020 at 91, wisely said, “Masturbation will get you through childhood, puberty, romance, marriage, and divorce, and it will see you through old age.” We can encourage women to see sexual play and pleasure flexibly, as a lifelong process of self-knowledge and discovery.
Basic Tips for Patients
- More “fiction and friction,” as coined by sex therapist Barry McCarthy, is necessary. As bodies age, more stimulation, both mental and physical, is necessary and often requires more direct physical stimulation of genitals.
- More time: Everything seems to take more time as we age; sex is no different.
- Incontinence concerns can be addressed by open communication and collaboration with partners, and being prepared with waterproof pads for the bed and towels.
- Ask about medical intervention–related sexual side effects. A wide range of medications can decrease desire and arousal and delay orgasm. If a change in sexual function occurred with starting a medication, it may be worthwhile investigating alternatives or, if possible, discontinuing a medication. Surgical and procedural changes to the anatomy also can affect sexual function. While correction may be impossible once certain changes have occurred, clinicians can provide patients with both validation about the problem and hope that, for the most part, with creativity and flexibility, pleasurable sexual experience is possible in all bodies.

Study IDs Immune Abnormality Possibly Causing Long COVID
Swiss scientists have identified immune system abnormalities in patients with long COVID that might open the door to new diagnostic tests and treatments.
The researchers found that a group of proteins in the blood that are part of the body’s immune response called the “complement system” are not working properly in patients with long COVID.
Blood samples turned up important differences between those who recovered from COVID and those who did not. These differences might be used as biomarkers to diagnose long COVID and might even point the way to new treatments for the condition, the researchers said.
By testing for 6500 blood proteins in about 300 patients, the Swiss researchers found that dysfunctional complement system proteins could possibly explain fatigue and “smoldering inflammation,” said Onur Boyman, MD, a professor of immunology from University Hospital Zurich in Zurich, Switzerland.
Long COVID has been linked to hundreds of symptoms including brain fog, chronic fatigue, pain, and digestive issues. Various factors drive the condition and likely work with one another other, said David Putrino, PhD, from the Icahn School of Medicine at Mount Sinai in New York City. The Swiss study is useful because “we’re trying to best understand how we can explain all of this far-reaching pathobiology,” he said.
Testing Across Continents
Dr. Boyman’s team collected blood samples from people with COVID in Europe and New York and tracked them. They compared those who developed long COVID with those who did not. One protein that was most unique to patients with long COVID is a blood complement that activates the immune system, Dr. Boyman said. But in people with long COVID, the immune response stays activated after the virus is gone. He described the response as “smoldering inflammation” in multiple organs, including the lungs and the gastrointestinal system.
The complement system also plays a role in clearing the body of dead cells. If the cells “lie around too much,” they can trigger an immune response, he said.
That may explain exercise intolerance in people with long COVID, Dr. Boyman said. Some people with long COVID have inflammation in the epithelium — the inner layer of their blood vessels. This would make it harder for the circulatory systems to recover from exercise, Dr. Boyman said.
“We think this regulated complement system is actually quite a central piece of the puzzle,” he said.
The Microclot Connection
The findings also support past research linking blood clots to long COVID. He suggested that clinicians and researchers consider testing drugs that regulate or inhibit the complementary system as a treatment of long COVID. Dr. Boyman said they are currently used for rare immune diseases.
Resia Pretorius, PhD, a professor of physiological sciences at Stellenbosch University in Stellenbosch, South Africa, said scientists studying the role of microclots in patients with long COVID often see complementary proteins inside the clots, so it has already been associated with long COVID. But she likened this clotting process to a garbage can that “just rolls along and collects everything that gets in its way. I think they are actively driving inflammation and disease.”
One factor complicating long COVID diagnosis and treatment is that it is a complex condition that involves multiple organ systems. That’s why the latest research suggests an underlying driver for the multiple symptoms of long COVID, Dr. Putrino said.
“Not every person has every symptom; not every person has every organ system affected,” Dr. Putrino said. “Whatever is happening is decided across the whole body.”
Research Offers New Direction
The Swiss paper contributes to the effort to identify systemic issues contributing to long COVID. It gives researchers one more thing to test for and link to specific, long COVID symptoms, opening the door to new treatments, Dr. Putrino said.
He doesn’t think the study supports treating the complement dysfunction if researchers don’t know what’s driving it. It may be complicated by the body’s failure to clear the virus completely, he said.
Dr. Pretorius recommended doctors test patients with long COVID for specific symptoms that may be treated using existing therapies. “If you think your patient had vascular pathology, you can test for it,” she said.
Some patients have found certain supplements and over-the-counter products helpful, she said. Among them: Coenzyme Q 10 and clot-busters such as streptokinase and Nattokinase (though she noted some doctors may not be comfortable with supplements).
“It’s the only thing we have until we’ve got trials,” she said.
Dr. Putrino said more research is needed to identify potential root causes and symptoms. A common refrain, but the only thing that will lead to specific treatments.

Boosting Vitamin E Intake May Protect Against MASLD
TOPLINE:
, particularly in adults without hyperlipidemia, new data showed.
METHODOLOGY:
- MASLD (formerly known as nonalcoholic fatty liver disease) is a common chronic liver disease, and its severe form — metabolic dysfunction–associated steatohepatitis (formerly nonalcoholic steatohepatitis) — is associated with oxidative stress. As an antioxidant, vitamin E may protect against MASLD.
- Researchers analyzed data for 6122 adults from the National Health and Nutrition Examination Survey from 2017 to 2020.
- Information on dietary, supplementary, and total vitamin E intake was obtained from two 24-hour dietary recall interviews.
- The extent of hepatic steatosis was measured by liver ultrasound transient elastography, with MASLD defined as a controlled attenuated parameter threshold of ≥ 288 dB/m.
TAKEAWAY:
- After adjustment for sociodemographic characteristics, adults with MASLD had lower dietary and total intake of vitamin E, and dietary and total vitamin E intake was inversely associated with MASLD outcome.
- Adults in the top quartile of dietary vitamin E intake had approximately 40% lower odds of MASLD (odds ratio [OR], 0.60; P = .0091).
- Vitamin E supplement use was associated with 34% reduced odds of MASLD (OR, 0.66; P = .0249), whereas adults in the top quartile of total vitamin E intake had a 33% lower likelihood of MASLD (OR, 0.67; P = .0538).
- The findings were robust to sensitivity analysis, and the effects were stronger in those without hyperlipidemia.
IN PRACTICE:
“Increasing dietary sources of vitamin E is beneficial for preventing [MASLD], particularly in individuals without hyperlipidemia,” the researchers concluded.
SOURCE:
The study, with first author Xiangjun Qi, Guangzhou University of Chinese Medicine, Guangzhou, China, was published online in Scientific Reports.
LIMITATIONS:
Causality cannot be determined due to the cross-sectional study design. Dietary recalls may not fully reflect the dietary status of participants, which may influence assessment of exposure to some extent.
DISCLOSURES:
The study had no specific funding. The authors declared no conflicts of interest.

- After adjustment for sociodemographic characteristics, adults with MASLD had lower dietary and total intake of vitamin E, and dietary and total vitamin E intake was inversely associated with MASLD outcome.
- Adults in the top quartile of dietary vitamin E intake had approximately 40% lower odds of MASLD (odds ratio [OR], 0.60; P = .0091).
- Vitamin E supplement use was associated with 34% reduced odds of MASLD (OR, 0.66; P = .0249), whereas adults in the top quartile of total vitamin E intake had a 33% lower likelihood of MASLD (OR, 0.67; P = .0538).
- The findings were robust to sensitivity analysis, and the effects were stronger in those without hyperlipidemia.
IN PRACTICE:
“Increasing dietary sources of vitamin E is beneficial for preventing [MASLD], particularly in individuals without hyperlipidemia,” the researchers concluded.

The study, with first author Xiangjun Qi, Guangzhou University of Chinese Medicine, Guangzhou, China, was published online in Scientific Reports.
LIMITATIONS:
Causality cannot be determined due to the cross-sectional study design. Dietary recalls may not fully reflect the dietary status of participants, which may influence assessment of exposure to some extent.
DISCLOSURES:
The study had no specific funding. The authors declared no conflicts of interest.
