TOPLINE:

For older adults with obesity, bariatric surgery does not appear to significantly reduce the risk for obesity-related cancer and cardiovascular disease (CVD), as it does in younger adults.

METHODOLOGY:

  • Bariatric surgery has been shown to decrease the risk for obesity-related cancer and CVD but is typically reserved for patients aged < 60 years. Whether the same holds for patients who undergo surgery at older ages is unclear.
  • Researchers analyzed nationwide data from three countries (Denmark, Finland, and Sweden) to compare patients with no history of cancer or CVD and age ≥ 60 years who underwent bariatric surgery against matched controls who received nonoperative treatment for obesity.
  • The main outcome was obesity-related cancer, defined as a composite outcome of breast, endometrial, esophageal, colorectal, and kidney cancer. The secondary outcome was CVD, defined as a composite of myocardial infarction, ischemic stroke, and cerebral hemorrhage.
  • Analyses were adjusted for diabetes, hypertension, peripheral vascular disease, chronic obstructive pulmonary disease, kidney disease, and frailty.

TAKEAWAY:

  • Of the 15,300 patients (66.4% women) included, 2550 underwent bariatric surgery (including gastric bypass in 1930) and 12,750 matched controls received nonoperative treatment for obesity.
  • During a median 5.8 years of follow-up, 658 (4.3%) people developed obesity-related cancer and 1436 (9.4%) developed CVD.
  • Bariatric surgery in adults aged ≥ 60 years was not associated with a reduced risk for obesity-related cancer (hazard ratio [HR], 0.81) or CVD (HR, 0.86) compared with matched nonoperative controls.
  • Bariatric surgery appeared to be associated with a decreased risk for obesity-related cancer in women (HR, 0.76).
  • There was a decreased risk for both obesity-related cancer (HR, 0.74) and CVD (HR, 0.82) in patients who underwent gastric bypass.

IN PRACTICE:

“The findings from this study suggest a limited role of bariatric surgery in older patients for the prevention of obesity-related cancer or cardiovascular disease,” the authors wrote, noting that this “may be explained by the poorer weight loss and resolution of comorbidities observed in patients who underwent surgery at an older age.”

SOURCE:

The study, with first author Peter Gerber, MD, PhD, Department of Surgery, Capio St Göran’s Hospital, Stockholm, Sweden, was published online in JAMA Network Open.

LIMITATIONS:

Data on smoking status and body mass index were not available. The observational design limited the ability to draw causal inferences. The null association between bariatric surgery and outcomes may be due to limited power.

DISCLOSURES:

The study was funded by the Swedish Society of Medicine. The authors reported no conflicts of interest.

Current Hydroxychloroquine Use in Lupus May Provide Protection Against Cardiovascular Events

Article Type

Wed, 09/11/2024 - 14:33

 

TOPLINE:

Current use of hydroxychloroquine is associated with a lower risk for myocardial infarction (MI), stroke, and other thromboembolic events in patients with systemic lupus erythematosus (SLE). This protective effect diminishes after discontinuation of hydroxychloroquine treatment.

METHODOLOGY:

  • Researchers used a nested case-control design to evaluate the association between exposure to hydroxychloroquine and the risk for cardiovascular events in patients with SLE.
  • They included 52,883 adults with SLE (mean age, 44.23 years; 86.6% women) identified from the National System of Health Databases, which includes 99% of the French population.
  • Among these, 1981 individuals with composite cardiovascular conditions were matched with 16,892 control individuals without cardiovascular conditions.
  • Patients were categorized on the basis of hydroxychloroquine exposure into current users (last exposure within 90 days before a cardiovascular event), remote users (91-365 days before), and nonusers (no exposure within 365 days).
  • The study outcomes included a composite of cardiovascular events, including MI, stroke (including transient ischemic attack), and other thromboembolic events such as phlebitis, thrombophlebitis, venous thrombosis, venous thromboembolism, and pulmonary embolism.

TAKEAWAY:

  • Current hydroxychloroquine users had lower odds of experiencing a composite cardiovascular outcome than nonusers (adjusted odds ratio [aOR], 0.63; 95% CI, 0.57-0.70).
  • The odds of MI (aOR, 0.72; 95% CI, 0.60-0.87), stroke (aOR, 0.71; 95% CI, 0.61-0.83), and other thromboembolic events (aOR, 0.58; 95% CI, 0.48-0.69) were also lower among current users than among nonusers.
  • No significant association was found for remote hydroxychloroquine exposure and the risk for composite cardiovascular events, MI, stroke, and other thromboembolic events.

IN PRACTICE:

“These findings support the protective association of hydroxychloroquine against CV [cardiovascular] events and underscore the importance of continuous hydroxychloroquine therapy for patients diagnosed with SLE,” the authors wrote.

SOURCE:

The study was led by Lamiae Grimaldi-Bensouda, PharmD, PhD, Department of Pharmacology, Hospital Group Paris-Saclay, Assistance Publique-Hôpitaux de Paris, France. It was published online on August 30, 2024, in JAMA Network Open.

LIMITATIONS:

The observational nature of the study may have introduced confounding. Current hydroxychloroquine users were younger than nonusers, with an average age difference of almost 5 years. Current hydroxychloroquine users had a twofold longer duration of onset of SLE and had a higher prevalence of chronic kidney disease compared with nonusers.

DISCLOSURES:

This study was funded by the Banque pour l’Investissement, Deeptech. Some authors declared having financial ties with various institutions and companies outside of the current study.

Eating the Right Fats May Help Patients Live Longer

Article Type
Changed
Wed, 09/11/2024 - 13:58

 

A diet in which the primary source of fat is plant sources is associated with decreased mortality. Animal fat, on the other hand, is associated with an increased risk for death. These are the results of a study published in JAMA Internal Medicine that followed more than 600,000 participants over 2 decades.

Bin Zhao, PhD, of the National Clinical Research Center for Metabolic Diseases at the Key Laboratory of Diabetes Immunology in Changsha, China, and colleagues concluded from these data that consuming plant-based fats instead of animal fats could be beneficial for health and improve survival.

It may not be so simple, however. “We are one step ahead of the publication: We no longer just distinguish between animal and plant fats but mainly consider the composition,” said Stefan Lorkowski, PhD, chair of biochemistry and physiology of nutrition at the Institute of Nutritional Sciences at the University of Jena in Germany, in response to inquiries from this news organization.
 

What’s in a Fat?

Although Dr. Zhao and colleagues studied the effect of different plant and animal fat sources (eg, grains, nuts, legumes, plant oils, red and white meat, dairy, eggs, and fish), they did not consider the composition of the fatty acids that they contained. “It matters which dairy products, which plant oils, and which fish are consumed,” said Dr. Lorkowski.

The data analyzed in the Chinese study come from a prospective cohort study (NIH-AARP Diet and Health Study) conducted in the United States from 1995 to 2019. At the beginning, the 407,531 study participants (average age, 61 years) filled out dietary questionnaires once. They were then followed for up to 24 years for total and cardiovascular mortality.

During this period, 185,111 study participants died, including 58,526 from cardiovascular diseases. Participants who consumed the most plant-based fats, according to the dietary questionnaires filled out in 1995, had a lower risk for death than those who consumed the least plant-based fats. Their overall mortality risk was 9% lower, and their cardiovascular mortality risk was 14% lower. This finding was especially noticeable when it came to plant fats from grains or plant oils.
 

Animal Fat and Mortality

In contrast, a higher intake of animal fat was associated with both a higher overall mortality risk (16%) and a higher cardiovascular mortality risk (14%). This was especially true for fat from dairy products and eggs.

A trend towards a reduced overall and cardiovascular mortality risk was observed for fat from fish. “The fact that only a trend towards fish consumption was observed may be due to the study having many more meat eaters than fish eaters,” said Dr. Lorkowski.

Another imbalance limits the significance of the study, he added. The two groups, those who primarily consumed plant fats and those who primarily consumed animal fats, were already distinct at the beginning of the study. Those who consumed more plant fats were more likely to have diabetes, a higher body mass index (BMI), higher energy intake, and higher alcohol consumption but consumed more fiber, fruits, and vegetables and were more physically active. “They may have been trying to live healthier because they were sicker,” said Dr. Lorkowski.
 

Potential Confounding

Dr. Zhao and his team adjusted the results for various potential confounding factors, including age, gender, BMI, ethnicity, smoking, physical activity, education, marital status, diabetes, health status, vitamin intake, protein, carbohydrates, fiber, trans fats, cholesterol intake, and alcohol consumption. However, according to Dr. Lorkowski, “statistical adjustment is always incomplete, and confounding cannot be completely ruled out.”

Nevertheless, these results provide relevant insights for dietary recommendations that could help improve health and related outcomes, according to the authors. “Replacement of 5% energy from animal fat with 5% energy from plant fat, particularly fat from grains or vegetable oils, was associated with a lower risk for mortality: 4%-24% reduction in overall mortality and 5%-30% reduction in cardiovascular disease mortality.”
 

Fat Composition Matters

Animal fat, however, should not simply be replaced with plant fat, said Dr. Lorkowski. “Cold-water fish, which provides important long-chain omega-3 fatty acids, is also considered animal fat. And palm and coconut fat, while plant-based, contain unhealthy long-chain saturated fats. And the type of plant oils also makes a difference, whether one uses corn germ or sunflower oil rich in omega-6 fatty acids or flaxseed or rapeseed oil rich in omega-3 fatty acids.

“A diet rich in unsaturated fats, with sufficient and balanced intake of omega-3 and omega-6 fatty acids, that is also abundant in fiber-rich carbohydrate sources and plant-based protein, is always better than too much fat from animal sources.”

TOPLINE:

— Elevated interleukin (IL) 6 levels are associated with an increased risk for obesity-related cancers in patients newly diagnosed with type 2 diabetes (T2D), potentially enabling the identification of higher-risk individuals through a simple blood test.

METHODOLOGY:

  • T2D is associated with an increased risk for obesity-related cancers, including breast, renal, uterine, thyroid, ovarian, and gastrointestinal cancers, as well as multiple myeloma, possibly because of chronic low-grade inflammation.
  • Researchers explored whether the markers of inflammation IL-6, tumor necrosis factor alpha (TNF-alpha), and high-sensitivity C-reactive protein (hsCRP) can serve as predictive biomarkers for obesity-related cancers in patients recently diagnosed with T2D.
  • They identified patients with recent-onset T2D and no prior history of cancer participating in the ongoing Danish Centre for Strategic Research in Type 2 Diabetes cohort study.
  • At study initiation, plasma levels of IL-6 and TNF-alpha were measured using Meso Scale Discovery assays, and serum levels of hsCRP were measured using immunofluorometric assays.

TAKEAWAY:

  • Among 6,466 eligible patients (40.5% women; median age, 60.9 years), 327 developed obesity-related cancers over a median follow-up of 8.8 years.
  • Each SD increase in log-transformed IL-6 levels increased the risk for obesity-related cancers by 19%.
  • The researchers did not find a strong association between TNF-alpha or hsCRP and obesity-related cancers.
  • The addition of baseline IL-6 levels to other well-known risk factors for obesity-related cancers improved the performance of a cancer prediction model from 0.685 to 0.693, translating to a small but important increase in the ability to predict whether an individual would develop one of these cancers.

IN PRACTICE:

“In future, a simple blood test could identify those at higher risk of the cancers,” said the study’s lead author in an accompanying press release.

SOURCE:

The study was led by Mathilde D. Bennetsen, Steno Diabetes Center Odense, Odense University Hospital, Odense, Denmark, and published online on August 27 as an early release from the European Association for the Study of Diabetes (EASD) 2024 Annual Meeting.

LIMITATIONS:

No limitations were discussed in this abstract. However, the reliance on registry data may have introduced potential biases related to data accuracy and completeness.

DISCLOSURES:

The Danish Centre for Strategic Research in Type 2 Diabetes was supported by grants from the Danish Agency for Science and the Novo Nordisk Foundation. The authors declared no conflicts of interest.

Remedies for Menopause Symptoms Show Short-Term Benefit, Need Long-Term Data

Article Type

Wed, 09/11/2024 - 12:49

 

A more definitive picture of how some hormones and moisturizers can offer relief to women experiencing vaginal dryness or painful intercourse during menopause was published in a recent systematic review in Annals of Internal Medicine. However, researchers noted scant long-term data on the safety of these products.

Vaginal dryness and challenges with intercourse and urination are among the symptoms of genitourinary syndrome of menopause (GSM). Hormones such as vaginal estrogen, vaginal dehydroepiandrosterone (DHEA), or oral ospemifene are common treatments, along with moisturizers.

“The main finding is that commonly used therapies are likely to be effective for the common symptoms people have for GSM,” particularly vaginal dryness and painful intercourse, said Elisheva Danan, MD, MPH, a primary care physician and health services researcher at the Minneapolis VA Health Care System and assistant professor of medicine at the University of Minnesota Medical School in Minneapolis, who was the lead study author.

Many women might recognize hot flashes as connected to menopause, Dr. Danan said, as these tend to occur with the cessation of the menstrual cycle. However, genitourinary effects may not manifest until a few years later and worsen over time, when the connection to menopause is less clear.

“Women might not bring it up or think there’s a treatment that can work,” Dr. Danan said.

The systematic review may provide clinicians with more evidence of specific treatments to recommend. However, most of the trials included in the analysis studied treatment periods of 12 weeks or less, so the safety of long-term use is unclear.

“One question that hasn’t been answered yet in clinical trials is whether there could be a risk of uterine cancer with extended use of any of these treatments,” Dr. Danan said, because vaginal estrogen or ospemifene could stimulate growth of the uterine lining.

The studies Dr. Danan and colleagues found showed no increased risk for uterine cancer, but Dr, Danan noted that the maximum follow-up was 1 year, and study participants had a low risk for cancer to begin with. She advised that clinicians closely monitor women with risk factors if they use hormones to treat GSM indefinitely.
 

Forty-Six Randomized Controlled Trials, Many Open Questions

Dr. Danan and her colleagues conducted a systematic review of 46 randomized controlled trials, meant to inform an upcoming clinical practice guideline from the American Urological Association on treatment of GSM. Dr. Danan’s work was funded by the Patient-Centered Outcomes Research Institute.

Studies evaluated vaginal estrogen (22), other hormones such as vaginal oxytocin or vaginal testosterone (16), vaginal moisturizers (4), and multiple interventions (4).

Included trials lasted at least 8 weeks and included at least 20 postmenopausal women; most treatments lasted 12 weeks or less. Studies used varying definitions of GSM, and no head-to-head trials of different treatments were found.

Researchers used the Core Outcomes in Menopause (COMMA) framework, developed in 2021 to standardize outcomes research in menopause care and to understand treatment effectiveness. They applied this framework retroactively, as almost all the studies in the review were written before the COMMA framework existed.

Hormonal treatments were associated with reduced pain during intercourse and decreased vaginal dryness; moisturizers were linked to reduced dryness.

Vaginal estrogen did not reduce pain during intercourse as consistently as DHEA or oral ospemifene, per the review. Dr. Danan and her coauthors said this could be because the DHEA and ospemifene trials were larger and more uniformly conducted than those for vaginal estrogen. Even so, vaginal estrogen outperformed placebo at reducing painful intercourse.

But given the short timeframe of most studies and the differing definitions of GSM symptoms, Dr. Danan cautioned that all their conclusions have low certainty.

Few studies examined whether these treatments reduced vaginal itchiness or difficulties with urination. And the authors found no evidence for the benefit of oral DHEA, raloxifene, bazedoxifene, vaginal oxytocin, or vaginal testosterone for GSM treatment.

In an accompanying report, the researchers found no evidence for the benefits of treatments such as vaginal testosterone or vaginal laser therapy.

Stephanie Faubion, MD, MBA, medical director for the North American Menopause Society and director of the Mayo Clinic Center for Women’s Health, Rochester, Minnesota, wrote an accompanying editorial noting that the patients represented in the GSM treatment clinical trials were not diverse and that the exclusion criteria generally meant that women with cardiovascular challenges or cancer were not included.

“That’s one of the biggest questions — what is the safety in women with cardiovascular risk factors or history of a blood clot or history of a cancer? The data is just completely absent there,” Dr. Faubion said.
 

 

 

The Connection Between GSM and Urinary Tract Infections (UTIs)

“Genitourinary syndrome of menopause is not just a little bit of vaginal dryness that can be cured with moisturizers and lubricants, but the syndrome can lead to recurrent urinary tract infections, which are extremely harmful and dangerous to our patients and cost the healthcare system a lot of money,” said Rachel Rubin, MD, a urologist and sexual medicine specialist in Bethesda, Maryland.

Lubricants and moisturizers can all help with the symptoms of GSM, at least in the short term, Dr. Rubin noted. But only hormones can get to the root of the problem and reduce the risk for a recurrent UTI (rUTI), Dr. Rubin added, noting that the American Urological Association recommends the use of vaginal estrogen to reduce the risk for rUTIs and is developing the clinical practice guidelines for GSM.

Dr. Danan’s review did not address the association between UTIs and GSM, but Dr. Rubin said she sees the link in clinical practice.

“Recurrent urinary tract infections occur because of GSM, because of the lack of hormones to the tissue,” sometimes when a woman is in her 60s or 70s and thinks menopause is long over, Dr. Rubin said.

The reality is that women may need to take hormones for decades to reduce the risk for UTIs, another reason longer-term safety data are needed, Dr. Rubin said.

Dr. Danan, Dr. Faubion, and Dr. Rubin reported no relevant financial relationships.

Not Kidding: Yellow Dye 5 May Lead to Invisibility

Article Type
Changed
Tue, 09/10/2024 - 12:16

 

The same dye that gives Twinkies their yellowish hue could be the key to invisibility. 

Applying the dye to lab mice made their skin temporarily transparent, allowing Stanford University researchers to observe the rodents’ digestive system, muscle fibers, and blood vessels, according to a study published in Science.

“It’s a stunning result,” said senior author Guosong Hong, PhD, who is assistant professor of materials science and engineering at Stanford University in California. “If the same technique could be applied to humans, it could offer a variety of benefits in biology, diagnostics, and even cosmetics.” 

The work drew upon optical concepts first described in the early 20th century to form a surprising theory: Applying a light-absorbing substance could render skin transparent by reducing the chaotic scattering of light as it strikes proteins, fats, and water in tissue. 

A search for a suitable light absorber led to FD&C Yellow 5, also called tartrazine, a synthetic color additive certified by the Food and Drug Administration (FDA) for use in foods, cosmetics, and medications. 

Rubbed on live mice (after areas of fur were removed using a drugstore depilatory cream), tartrazine rendered skin on their bellies, hind legs, and heads transparent within 5 minutes. With the naked eye, the researchers watched a mouse’s intestines, bladder, and liver at work. Using a microscope, they observed muscle fibers and saw blood vessels in a living mouse’s brain — all without making incisions. Transparency faded quickly when the dye was washed off.

Someday, the concept could be used in doctors’ offices and hospitals, Dr. Hong said. 

“Instead of relying on invasive biopsies, doctors might be able to diagnose deep-seated tumors by simply examining a person’s tissue without the need for invasive surgical removal,” he said. “This technique could potentially make blood draws less painful by helping phlebotomists easily locate veins under the skin. It could also enhance procedures like laser tattoo removal by allowing more precise targeting of the pigment beneath the skin.”
 

From Cake Frosting to Groundbreaking Research

Yellow 5 food dye can be found in everything from cereal, soda, spices, and cake frosting to lipstick, mouthwash, shampoo, dietary supplements, and house paint. Although it’s in some topical medications, more research is needed before it could be used in human diagnostics, said Christopher J. Rowlands, PhD, a senior lecturer in the Department of Bioengineering at Imperial College London, England, where he studies biophotonic instrumentation — ways to image structures inside the body more quickly and clearly. 

But the finding could prove useful in research. In a commentary published in Science, Dr. Rowlands and his colleague Jon Gorecki, PhD, an experimental optical physicist also at Imperial College London, noted that the dye could be an alternative to other optical clearing agents currently used in lab studies, such as glycerol, fructose, or acetic acid. Advantages are the effect is reversible and works at lower concentrations with fewer side effects. This could broaden the types of studies possible in lab animals, so researchers don’t have to rely on naturally transparent creatures like nematodes and zebrafish. 

The dye could also be paired with imaging techniques such as MRI or electron microscopy. 

“Imaging techniques all have pros and cons,” Dr. Rowlands said. “MRI can see all the way through the body albeit with limited resolution and contrast. Electron microscopy has excellent resolution but limited compatibility with live tissue and penetration depth. Optical microscopy has subcellular resolution, the ability to label things, excellent biocompatibility but less than 1 millimeter of penetration depth. This clearing method will give a substantial boost to optical imaging for medicine and biology.”

The discovery could improve the depth imaging equipment can achieve by tenfold, according to the commentary. 

Brain research especially stands to benefit. “Neurobiology in particular will have great use for combinations of multiphoton, optogenetics, and tissue clearing to record and control neural activity over (potentially) the whole mouse brain,” he said.
 

Refraction, Absorption, and The Invisible Man

The dye discovery has distant echoes in H.G. Wells’ 1897 novel The Invisible Man, Dr. Rowlands noted. In the book, a serum makes the main character invisible by changing the light scattering — or refractive index (RI) — of his cells to match the air around him.

The Stanford engineers looked to the past for inspiration, but not to fiction. They turned to a concept first described in the 1920s called the Kramers-Kronig relations, a mathematical principle that can be applied to relationships between the way light is refracted and absorbed in different materials. They also read up on Lorentz oscillation, which describes how electrons and atoms inside molecules react to light. 

They reasoned that light-absorbing compounds could equalize the differences between the light-scattering properties of proteins, lipids, and water that make skin opaque. 

With that, the search was on. The study’s first author, postdoctoral researcher Zihao Ou, PhD, began testing strong dyes to find a candidate. Tartrazine was a front-runner. 

“We found that dye molecules are more efficient in raising the refractive index of water than conventional RI-matching agents, thus resulting in transparency at a much lower concentration,” Dr. Hong said. “The underlying physics, explained by the Lorentz oscillator model and Kramers-Kronig relations, reveals that conventional RI matching agents like fructose are not as efficient because they are not ‘colored’ enough.”
 

What’s Next

Though the dye is already in products that people consume and apply to their skin, medical use is years away. In some people, tartrazine can cause skin or respiratory reactions. 

The National Science Foundation (NSF), which helped fund the research, posted a home or classroom activity related to the work on its website. It involves painting a tartrazine solution on a thin slice of raw chicken breast, making it transparent. The experiment should only be done while wearing a mask, eye protection, lab coat, and lab-quality nitrile gloves for protection, according to the NSF.

Meanwhile, Dr. Hong said his lab is looking for new compounds that will improve visibility through transparent skin, removing a red tone seen in the current experiments. And they’re looking for ways to induce cells to make their own “see-through” compounds. 

“We are exploring methods for cells to express intensely absorbing molecules endogenously, enabling genetically encoded tissue transparency in live animals,” he said.

Someday, the concept could be used in doctors’ offices and hospitals, Dr. Hong said. 

“Instead of relying on invasive biopsies, doctors might be able to diagnose deep-seated tumors by simply examining a person’s tissue without the need for invasive surgical removal,” he said. “This technique could potentially make blood draws less painful by helping phlebotomists easily locate veins under the skin. It could also enhance procedures like laser tattoo removal by allowing more precise targeting of the pigment beneath the skin.”
 

From Cake Frosting to Groundbreaking Research

Yellow 5 food dye can be found in everything from cereal, soda, spices, and cake frosting to lipstick, mouthwash, shampoo, dietary supplements, and house paint. Although it’s in some topical medications, more research is needed before it could be used in human diagnostics, said Christopher J. Rowlands, PhD, a senior lecturer in the Department of Bioengineering at Imperial College London, England, where he studies biophotonic instrumentation — ways to image structures inside the body more quickly and clearly. 

But the finding could prove useful in research. In a commentary published in Science, Dr. Rowlands and his colleague Jon Gorecki, PhD, an experimental optical physicist also at Imperial College London, noted that the dye could be an alternative to other optical clearing agents currently used in lab studies, such as glycerol, fructose, or acetic acid. Advantages are the effect is reversible and works at lower concentrations with fewer side effects. This could broaden the types of studies possible in lab animals, so researchers don’t have to rely on naturally transparent creatures like nematodes and zebrafish. 

The dye could also be paired with imaging techniques such as MRI or electron microscopy. 

“Imaging techniques all have pros and cons,” Dr. Rowlands said. “MRI can see all the way through the body albeit with limited resolution and contrast. Electron microscopy has excellent resolution but limited compatibility with live tissue and penetration depth. Optical microscopy has subcellular resolution, the ability to label things, excellent biocompatibility but less than 1 millimeter of penetration depth. This clearing method will give a substantial boost to optical imaging for medicine and biology.”

The discovery could improve the depth imaging equipment can achieve by tenfold, according to the commentary. 

Brain research especially stands to benefit. “Neurobiology in particular will have great use for combinations of multiphoton, optogenetics, and tissue clearing to record and control neural activity over (potentially) the whole mouse brain,” he said.
 

Refraction, Absorption, and The Invisible Man

The dye discovery has distant echoes in H.G. Wells’ 1897 novel The Invisible Man, Dr. Rowlands noted. In the book, a serum makes the main character invisible by changing the light scattering — or refractive index (RI) — of his cells to match the air around him.

The Stanford engineers looked to the past for inspiration, but not to fiction. They turned to a concept first described in the 1920s called the Kramers-Kronig relations, a mathematical principle that can be applied to relationships between the way light is refracted and absorbed in different materials. They also read up on Lorentz oscillation, which describes how electrons and atoms inside molecules react to light. 

They reasoned that light-absorbing compounds could equalize the differences between the light-scattering properties of proteins, lipids, and water that make skin opaque. 

With that, the search was on. The study’s first author, postdoctoral researcher Zihao Ou, PhD, began testing strong dyes to find a candidate. Tartrazine was a front-runner. 

“We found that dye molecules are more efficient in raising the refractive index of water than conventional RI-matching agents, thus resulting in transparency at a much lower concentration,” Dr. Hong said. “The underlying physics, explained by the Lorentz oscillator model and Kramers-Kronig relations, reveals that conventional RI matching agents like fructose are not as efficient because they are not ‘colored’ enough.”
 

What’s Next

Though the dye is already in products that people consume and apply to their skin, medical use is years away. In some people, tartrazine can cause skin or respiratory reactions. 

The National Science Foundation (NSF), which helped fund the research, posted a home or classroom activity related to the work on its website. It involves painting a tartrazine solution on a thin slice of raw chicken breast, making it transparent. The experiment should only be done while wearing a mask, eye protection, lab coat, and lab-quality nitrile gloves for protection, according to the NSF.

Meanwhile, Dr. Hong said his lab is looking for new compounds that will improve visibility through transparent skin, removing a red tone seen in the current experiments. And they’re looking for ways to induce cells to make their own “see-through” compounds. 

“We are exploring methods for cells to express intensely absorbing molecules endogenously, enabling genetically encoded tissue transparency in live animals,” he said.

The same dye that gives Twinkies their yellowish hue could be the key to invisibility. 

Applying the dye to lab mice made their skin temporarily transparent, allowing Stanford University researchers to observe the rodents’ digestive system, muscle fibers, and blood vessels, according to a study published in Science.

“It’s a stunning result,” said senior author Guosong Hong, PhD, who is assistant professor of materials science and engineering at Stanford University in California. “If the same technique could be applied to humans, it could offer a variety of benefits in biology, diagnostics, and even cosmetics.” 

The work drew upon optical concepts first described in the early 20th century to form a surprising theory: Applying a light-absorbing substance could render skin transparent by reducing the chaotic scattering of light as it strikes proteins, fats, and water in tissue. 

A search for a suitable light absorber led to FD&C Yellow 5, also called tartrazine, a synthetic color additive certified by the Food and Drug Administration (FDA) for use in foods, cosmetics, and medications. 

Rubbed on live mice (after areas of fur were removed using a drugstore depilatory cream), tartrazine rendered skin on their bellies, hind legs, and heads transparent within 5 minutes. With the naked eye, the researchers watched a mouse’s intestines, bladder, and liver at work. Using a microscope, they observed muscle fibers and saw blood vessels in a living mouse’s brain — all without making incisions. Transparency faded quickly when the dye was washed off.

Being An Outsider

Article Type
Changed
Fri, 09/06/2024 - 16:44

Our son works for a Maine-based company that produces and sells clothing and outdoor recreation equipment. One of its tag lines is “Be an Outsider.” In his role as chief marketing officer, he was recently given an app for his phone that can calculate how many minutes he spends outside each day. He assured me: “Dad, you don’t need one of these on your phone. Your weather-beaten skin says you are already logging in way more than enough minutes outdoors.”

But, it got me thinking about several avenues of research where an app like that would be useful. As luck would have it, the following week I stumbled across a paper describing just such a study.

Dr. William G. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years.
Dr. William G. Wilkoff

Researchers in Shanghai, China, placed smartwatches with technology similar to my son’s phone on nearly 3000 children and found “that outdoor exposure patterns characterized by a continuous period of at least 15 minutes, accompanied by a sunlight intensity of more than 2000 lux, were associated with less myopic shift.” In other words, children getting more time outside were less likely to become nearsighted.” Whether this was an effect of being outside instead of staring at a screen indoors is an interesting question.

I have alway suspected that being outdoors was important for wellness and this paper meshed nicely with an article I had recently read in The Washington Post titled, “How time in nature builds happier, healthier and more social children” (Jamie Friedlander Serrano, 2024 Aug 4). The reporter quotes numerous experts in child health and includes links to several articles that tout the benefits of outdoor experiences, particularly ones in a natural environment. There are the vitamin D effects on growth and bone health. There are studies suggesting that being out in nature can reduce stress, anxiety, and aggression, and improve working memory and attention.

In this country there is a small but growing group of schools modeling themselves after the “Forest kindergartens” that have become popular in Europe in which a large portion of the students’ days are spent outside surrounded by nature. It will be interesting to see how robustly this trend grows here in the United States. However, in a nation like ours in which the Environmental Protection Agency estimates that the average American spends 90% of his day indoors, it’s going to require a seismic shift in our societal norms.

I think my mother always knew that being outdoors was healthy for children. I also suspect that she and most my friends’ mothers were primarily motivated by a desire to have the house to themselves. This was primarily to allow them to get the housework done unimpeded by pestering children. But, there may have been times when a busy housewife simply needed to sit down with a book in the peace and quiet of a childless environment. We kids were told to get out of the house and return for lunch and dinner, hopefully not in the tow of a police officer. There were few rules and for the most part we were left to invent our own amusement.

Yes, you’ve heard this old-fogey legend before. But it was true. Those were the halcyon days of the 1950s in a small suburban town of 5000 of a little more than 1 square mile with its own swimming pool. My particular idyll was aptly named Pleasantville but I know we were not alone as the only community where children were allowed – or let’s say “encouraged” – to be outdoors if they weren’t in school. It was a different time.

I am not so naive to believe that we will ever return to those good old days when children roamed free, but it is worth considering what has changed to drive children inside and away from all the health benefits of being outdoors. Is there anything we can do to reverse this unfortunate trend?

First, we must first face up to the reality that our society has become so focused on the potential downsides of everything that we seem to be driven primarily by risk avoidance. We hear how things can go terribly wrong in the world outside, a world we can’t control. Although the data from the pandemic don’t support it, more of us believe children are safer indoors. Parents in particular seem to worry more now than they did 75 years ago. I don’t think we can point to a single event such as the tragedies of September 11 to explain the shift.

While bad news has always traveled fast, today (with communication being almost instantaneous) a story about a child abduction at 6 in the morning in Nevada can be on my local TV channel by lunchtime here in Maine. Parents worry that if bad stuff can happen to a child in Mount Elsewhere, it could happen to my child playing in the backyard across the street.

I think we pediatricians should consider how large a role we may be playing in driving parental anxiety with our frequent warnings about the dangers a child can encounter outdoors whether they come in the form of accidents or exposure to the elements.

While parents have grown more hesitant to send their children outside to play, as a society we have failed to adequately acknowledge and respond to the role that unhealthy attraction of indoor alternatives to outdoor play may be contributing to indoorism. Here we’re talking about television, smartphones, and the internet.

So, what can we do as pediatricians to get our patients outside? First, we can set an example and cover our office walls with pictures of ourselves and our families enjoying the outdoors. We can be vocal advocates for creating and maintaining accessible outdoor spaces in our community. We can advocate for more outside time during recess in school and encourage the school officials to consider having more courses taught outside.

We can be more diligent in asking families about their screen use and not be afraid to express our concern when we hear how little outdoor time their child is getting. Finally, we can strive for more balance in our messaging. For example for every warning we give about playing outside on poor air quality days there should be a reminder of the health benefits of being outdoors on the other days. Every message about the importance of sunscreen should be preceded by a few sentences promoting outdoor activities in wooded environments where sun exposure is less of a concern.

We should all be looking for ways in which our communities can remove the barriers that prevent our patients for reaping the health benefits of being outdoors. Being an outsider is just as important as getting enough sleep, eating the right food and staying physically active.

Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.

High Breast Cancer Risk With Menopausal Hormone Therapy & Strong Family History

Article Type
Changed
Fri, 09/06/2024 - 12:04

 

TOPLINE:

The use of menopausal hormone therapy (MHT) increases breast cancer risk in women with a strong family history of breast cancer. These women have a striking cumulative risk of developing breast cancer (age, 50-80 years) of 22.4%, according to a new modelling study of UK women.

METHODOLOGY:

This was a modeling study integrating two data-sets of UK women: the BOADICEA dataset of age-specific breast cancer risk with family history and the Collaborative Group on Hormonal Factors in Breast Cancer, which covers relative risk for breast cancer with different types and durations of MHT.

Four different breast cancer family history profiles were:

  • “Average” family history of breast cancer has unknown affected family members;
  • “Modest” family history comprises a single first-degree relative with breast cancer at the age of 60 years.
  • “Intermediate” family history comprises a single first-degree relative who developed breast cancer at the age of 40 years.
  • “Strong” family history comprises two first-degree relatives who developed breast cancer at the age of 50 years.

TAKEAWAY:

  • The lowest risk category: “Average” family history with no MHT use has a cumulative breast cancer risk (age, 50-80 years) of 9.8% and a risk of dying from breast cancer of 1.7%. These risks rise with 5 years’ exposure to MHT (age, 50-55 years) to 11.0% and 1.8%, respectively.
  • The highest risk category: “Strong” family history with no MHT use has a cumulative breast cancer risk (age, 50-80 years) of 19.6% and a risk of dying from breast cancer of 3.2%. These risks rise with 5 years’ exposure to MHT (age, 50-55 years) to 22.4% and 3.5%, respectively.

IN PRACTICE:

The authors concluded that, “These integrated data will enable more accurate estimates of absolute and attributable risk associated with MHT exposure for women with a family history of breast cancer, informing shared decision-making.”

SOURCE:

The lead author is Catherine Huntley of the Institute of Cancer Research, London, England. The study appeared in the British Journal of General Practice.

LIMITATIONS:

Limitations included modeling study that did not directly measure individuals with combined risks.

DISCLOSURES:

The study was funded by several sources including Cancer Research UK. The authors reported no conflicts of interest.

  • “Modest” family history comprises a single first-degree relative with breast cancer at the age of 60 years.
  • “Intermediate” family history comprises a single first-degree relative who developed breast cancer at the age of 40 years.
  • “Strong” family history comprises two first-degree relatives who developed breast cancer at the age of 50 years.

TAKEAWAY:

  • The lowest risk category: “Average” family history with no MHT use has a cumulative breast cancer risk (age, 50-80 years) of 9.8% and a risk of dying from breast cancer of 1.7%. These risks rise with 5 years’ exposure to MHT (age, 50-55 years) to 11.0% and 1.8%, respectively.
  • The highest risk category: “Strong” family history with no MHT use has a cumulative breast cancer risk (age, 50-80 years) of 19.6% and a risk of dying from breast cancer of 3.2%. These risks rise with 5 years’ exposure to MHT (age, 50-55 years) to 22.4% and 3.5%, respectively.

IN PRACTICE:

The authors concluded that, “These integrated data will enable more accurate estimates of absolute and attributable risk associated with MHT exposure for women with a family history of breast cancer, informing shared decision-making.”

SOURCE:

The lead author is Catherine Huntley of the Institute of Cancer Research, London, England. The study appeared in the British Journal of General Practice.

LIMITATIONS:

Limitations included modeling study that did not directly measure individuals with combined risks.

DISCLOSURES:

The study was funded by several sources including Cancer Research UK. The authors reported no conflicts of interest.

TOPLINE:

The use of menopausal hormone therapy (MHT) increases breast cancer risk in women with a strong family history of breast cancer. These women have a striking cumulative risk of developing breast cancer (age, 50-80 years) of 22.4%, according to a new modelling study of UK women.

METHODOLOGY:

This was a modeling study integrating two data-sets of UK women: the BOADICEA dataset of age-specific breast cancer risk with family history and the Collaborative Group on Hormonal Factors in Breast Cancer, which covers relative risk for breast cancer with different types and durations of MHT.

Four different breast cancer family history profiles were:

  • “Average” family history of breast cancer has unknown affected family members;
  • “Modest” family history comprises a single first-degree relative with breast cancer at the age of 60 years.
  • “Intermediate” family history comprises a single first-degree relative who developed breast cancer at the age of 40 years.
  • “Strong” family history comprises two first-degree relatives who developed breast cancer at the age of 50 years.

TAKEAWAY:

  • The lowest risk category: “Average” family history with no MHT use has a cumulative breast cancer risk (age, 50-80 years) of 9.8% and a risk of dying from breast cancer of 1.7%. These risks rise with 5 years’ exposure to MHT (age, 50-55 years) to 11.0% and 1.8%, respectively.

Breast Cancer Hormone Therapy May Protect Against Dementia

Article Type
Changed
Fri, 09/06/2024 - 11:14

 

TOPLINE:

Hormone-modulating therapy for breast cancer may protect older women from Alzheimer’s disease and related dementias, although the protective effect varies by age and race, with the greatest benefit seen in younger Black women.

METHODOLOGY:

  • Hormone-modulating therapy is widely used to treat hormone receptor–positive breast cancer, but the cognitive effects of the treatment, including a potential link to dementia, remain unclear.
  • To investigate, researchers used the SEER-Medicare linked database to identify women aged 65 years or older with breast cancer who did and did not receive hormone-modulating therapy within 3 years following their diagnosis.
  • The researchers excluded women with preexisting Alzheimer’s disease/dementia diagnoses or those who had received hormone-modulating therapy before their breast cancer diagnosis.
  • Analyses were adjusted for demographic, sociocultural, and clinical variables, and subgroup analyses evaluated the impact of age, race, and type of hormone-modulating therapy on Alzheimer’s disease/dementia risk.

TAKEAWAY:

  • Among the 18,808 women included in the analysis, 66% received hormone-modulating therapy and 34% did not. During the mean follow-up of 12 years, 24% of hormone-modulating therapy users and 28% of nonusers developed Alzheimer’s disease/dementia.
  • Overall, hormone-modulating therapy use (vs nonuse) was associated with a significant 7% lower risk for Alzheimer’s disease/dementia (hazard ratio [HR], 0.93; P = .005), with notable age and racial differences.
  • Hormone-modulating therapy use was associated with a 24% lower risk for Alzheimer’s disease/dementia in Black women aged 65-74 years (HR, 0.76), but that protective effect decreased to 19% in Black women aged 75 years or older (HR, 0.81). White women aged 65-74 years who received hormone-modulating therapy (vs those who did not) had an 11% lower risk for Alzheimer’s disease/dementia (HR, 0.89), but the association disappeared among those aged 75 years or older (HR, 0.96; 95% CI, 0.90-1.02). Other races demonstrated no significant association between hormone-modulating therapy use and Alzheimer’s disease/dementia.
  • Overall, the use of an aromatase inhibitor or a selective estrogen receptor modulator was associated with a significantly lower risk for Alzheimer’s disease/dementia (HR, 0.93 and HR, 0.89, respectively).

IN PRACTICE:

Overall, the retrospective study found that “hormone therapy was associated with protection against [Alzheimer’s/dementia] in women aged 65 years or older with newly diagnosed breast cancer,” with the decrease in risk relatively greater for Black women and women younger than 75 years, the authors concluded.

“The results highlight the critical need for personalized breast cancer treatment plans that are tailored to the individual characteristics of each patient, particularly given the significantly higher likelihood (two to three times more) of Black women developing [Alzheimer’s/dementia], compared with their White counterparts,” the researchers added.
 

SOURCE:

The study, with first author Chao Cai, PhD, Department of Clinical Pharmacy and Outcomes Sciences, University of South Carolina, Columbia, was published online on July 16 in JAMA Network Open.

LIMITATIONS:

The study included only women aged 65 years or older, limiting generalizability to younger women. The dataset lacked genetic information and laboratory data related to dementia. The duration of hormone-modulating therapy use beyond 3 years and specific formulations were not assessed. Potential confounders such as variations in chemotherapy, radiation, and surgery were not fully addressed.

DISCLOSURES:

Support for the study was provided by the National Institutes of Health; Carolina Center on Alzheimer’s Disease and Minority Research pilot project; and the Dean’s Faculty Advancement Fund, University of Pittsburgh, Pennsylvania. The authors reported no relevant disclosures.

False-Positive Mammography Results Linked to Reduced Rates of Future Screenings

Article Type
Changed
Mon, 09/09/2024 - 14:43

 

TOPLINE:

Women who received false-positive mammography results were less likely to return for future screenings.

METHODOLOGY:

  • Researchers analyzed more than three million screening mammograms from more than one million women aged between 40 and 73 years at nearly 200 facilities in the Breast Cancer Surveillance Consortium between 2005 and 2017.
  • Mammography results were classified as true negative or false positive; women who received false-positive results were either asked to come back for additional imaging, a short interval follow-up or biopsy recommendations.
  • The primary outcome was the probability of returning for routine screening within 9-30 months after a false-positive or true-negative result, adjusted for race, ethnicity, age, and time since the last mammogram.
  • Women with two screening mammograms within 5 years were also analyzed to evaluate the probability of returning for a third screening based on combinations of true-negative and false-positive results.

TAKEAWAY:

  • Nearly 10.0% (95% CI, 9.1%-10.5%) of women who received screening mammograms got a false-positive result, 5.8% (95% CI, 5.5%-6.2%) of whom needed immediate additional imaging, 2.7% (95% CI, 2.3%-3.2%) needed short-interval follow-up, and 1.3% (95% CI, 1.1%-1.4%) were recommended for a biopsy.
  • Women were more likely to return for screening after a true-negative result (76.9%) than after a false positive to obtain more data through additional imaging (72.4%), short-interval follow-ups (54.7%), or biopsy (61.0%).
  • Asian and Hispanic/Latinx women who received a false-positive result were much less likely to return for a screening than women of the same groups who received a true-negative result, with recommendations for short interval follow-up (decrease of 20-25 percentage points) or biopsy (decrease of 13-14 percentage points).
  • For women who had two screening mammograms within 5 years, receiving a false-positive result on the second was linked to a lower likelihood of returning for a third screening, regardless of results for the first.

IN PRACTICE:

“Physicians should educate their patients about the importance of continued screening after false-positive results, especially given the associated increased future risk for breast cancer,” study authors wrote.

SOURCE:

The study was led by Diana L. Miglioretti, PhD, of the Department of Public Health Sciences at the University of California, Davis, and published online on September 3 in Annals of Internal Medicine.

LIMITATIONS:

Women could receive care at facilities outside of the trial, which may have affected the accuracy of return rates. The study did not track a complete history of false-positive results. The study did not have information about how often physicians recommend screenings and did not account for other health conditions.

DISCLOSURES:

One coauthor reported receiving grants from the National Institutes of Health and the American Cancer Society, as well as consulting fees from the University of Florida, Gainesville.
