  • New blood biomarkers identified to predict cardiovascular risk in rheumatoid arthritis patients

    New blood biomarkers identified to predict cardiovascular risk in rheumatoid arthritis patients

    [ad_1]

    Rheumatoid arthritis impacts approximately 2 million people in the United States and is associated with increased risk of cardiovascular disease. However, assessing cardiovascular risk is difficult in patients with rheumatoid arthritis because standard clinical assessments based on factors like age, cholesterol, and smoking status tend to underestimate cardiovascular risk in individuals with rheumatoid arthritis. 

    In a new study published in the Journal of the American Heart Association, a research team led by physicians at Mass General Brigham with expertise in rheumatology and cardiovascular disease identified six blood biomarkers that are associated with cardiovascular risk in patients with rheumatoid arthritis and whose measurements improved the researchers’ ability to predict a future increase in arterial inflammation. The biomarkers hold the potential to clinically assess an individual patient’s risk of cardiovascular disease, but more research is needed to determine whether they are associated with cardiovascular events such as heart attack or stroke.

    We think these biomarkers might improve our ability to predict risk and intervene early to help our patients. The idea is that if we measure biomarkers that are specific to rheumatoid arthritis, we might be able to better identify those at highest risk of cardiovascular events.”


    Daniel H. Solomon, MD, MPH, first author, chief of the Section of Clinical Sciences in the Division of Rheumatology and Matthew H. Liang Distinguished Chair at Brigham and Women’s Hospital, founding member of the Mass General Brigham healthcare system

    To identify rheumatoid arthritis-specific biomarkers of cardiovascular risk, the researchers assembled a panel of 24 candidate biomarkers that had been previously shown to be associated with rheumatoid arthritis and systemic inflammation. Then, they measured the concentration of these biomarkers in 109 patients with rheumatoid arthritis who were taking part in a randomized clinical trial (the TARGET Trial) to compare the efficacy of two different treatments for rheumatoid arthritis at preventing cardiovascular disease. The researchers measured the biomarkers at the beginning of the study and six months later, imaging the patients’ arteries at each time to assess their arterial inflammation-;an indicator of cardiovascular risk.

    “Arterial inflammation can predict future cardiovascular disease risk,” said cardiologist and co-author Ahmed Tawakol, MD, the director of Nuclear Cardiology and co-director of the Cardiovascular Imaging Research Center at Massachusetts General Hospital, a founding member of the Mass General Brigham healthcare system. “If you take a snapshot of a person’s blood vessels, the more inflammation that is measured there, the greater the likelihood the person will have progression of their disease, and the greater likelihood that they will have a stroke or a myocardial infarction.”

    Six of the 24 biomarkers were associated with increased cardiovascular risk and using them in predictive models improved the researchers’ ability to predict increases in arterial inflammation compared to standard clinical indices such as the Framingham Risk Score, which is based on factors such as age, sex, cholesterol, blood pressure, diabetes, and smoking.

    “This is an important step towards using blood samples to measure changes in cardiovascular risk with the treatment of rheumatoid arthritis,” said Solomon.

    The study showcases the strength of ongoing collaborations between Brigham and Women’s Hospital and Massachusetts General Hospital, said Solomon and Tawakol, who trained together as residents at the Brigham around 30 years ago. “Having two really great institutions collaborating in the same organization meant we could leverage the strengths of the respective institutions and teams,” said Solomon.

    Now, the team is working to test these biomarkers in a larger and more long-term cohort of rheumatoid arthritis patients, the Brigham and Women’s Rheumatoid Arthritis Sequential Study (BRASS), which has been following over 1,000 patients with rheumatoid arthritis since 2003. This follow-up study will allow the researchers to not only test associations between the biomarkers and arterial inflammation, but also assess whether the biomarkers can predict future cardiovascular events such as heart attack or stroke.

  • Better cognition and academic performance are associated with Mediterranean diet adherence

    Better cognition and academic performance are associated with Mediterranean diet adherence

    [ad_1]

    In a recent study published in Nutrients, researchers investigated the relationship between various Mediterranean-style eating patterns and cognitive and academic performance among adolescent residents of Chile.

    Background

    The Mediterranean diet (MedDiet) is a healthy eating pattern associated with higher cognitive and academic success among teenagers in developing nations.

    It consists of high extra-virgin olive oil, vegetable, fruit, grain, nut, and legume consumption, moderate fish, meat, and dairy product consumption, and low egg and sweet consumption. The MedDiet promotes reducing the intake of processed and sugary foods, alcohol, and smoking.

    The Western diet (WD), which includes ultra-processed foods, refined carbohydrates, and sugar, has been associated with cognitive decline in youngsters. In contrast, the MedDiet increases well-being and increased cognitive function.

    However, the association between MedDiet and academic and cognitive abilities in teenagers has not been thoroughly explored in Latina communities.

    About the study

    In the present study, researchers explored the association between different Mediterranean-style eating patterns and cognitive and academic ability in Chilean adolescents.

    The study was part of the Cogni-Action Project, which ran from March 2017 to October 2019 and involved 1,296 Chilean adolescents (males and females in a 1:1 ratio) aged 10 to 14 years from private, public, and subsidized (government-funded) schools in Chile.

    The researchers performed a cluster analysis to uncover dietary trends and mixed modeling to examine the associations of diet clusters with cognition and academics.

    The researchers used the MedDiet Quality Index to measure MedDiet adherence in children and adolescents and the NeuroCognitive Performance Test (NCPT) to assess cognitive performance.

    They used principal component analysis (PCA) to uncover four cognitive domains: cognitive flexibility (CF), working memory (WM), fluid reasoning (FR), and inhibitory control (IC).

    They assessed CF basis Trail-making tests A and B and Digit coding symbol tasks. WM tasks included memory forward and memory reverse, and the IC and FR assessments included the Go/No-Go and problem-solving tasks, respectively.

    The researchers assessed academic success across five school disciplines (English, Language, Science, History, and Mathematics), including the Academic-Programme for International Student Assessment (PISA) score calculated as the mean of Mathematics, Science, and Language scores.

    The study consisted of two sessions of participant evaluation spread over eight days. The first session evaluated body weight, height, waist circumference, eating habits, sociodemographic information, and a cognitive battery. The second session evaluated physical fitness using three factors (sex, maturity, and global fitness score).

    Results

    The team identified the following diet patterns: Western diet (WD, 4.3%), low fruits and vegetables, high-sugar diet (LFV-HSD, 28%), low fruits and vegetables, low-sugar diet (LFV-LSD, 42%), and MedDiet (25%).

    There was a remarkable difference among the dietary clusters, primarily related to ultra-processed food, sugar, vegetable, and fruit intake.

    Individuals in the Mediterranean diet group scored better in all cognitive domains compared to the Western diet, LFV-LSD, and LFV-HSD groups. The Western diet group underperformed academically in all assessments compared to other groups.

    The Mediterranean diet was unique, attaining positive differences among all subjects compared to the LFV-HSD and Western diet groups.

    The WD group exhibited lower performance across all cognitive domains than the MedDiet group except for inhibitory control. The MedDiet group showed positive differences in total cognitive performance, cognitive flexibility, inhibitory control, and working memory compared to the LFV-LSD cluster. However, fluid reasoning was not significantly different.

    The Western diet group individuals underperformed in academic analyses than those in other groups. The Mediterranean diet cluster showed a significant difference in school students compared to the LFV-HSD and WD groups.

    The MedDiet group scored better across all academic subjects than their LFV-LSD group counterparts; however, the differences did not attain statistical significance.

    Conclusions

    The study findings showed that Mediterranean-style eating patterns and higher-quality food preferences are related to superior adolescent academic and cognitive outcomes.

    The study highlighted four dietary patterns: Western diet, LFV-LSD, LFV-HSD, and MedDiet, determined by adolescent adherence to or lack of particular MedDiet components. These clusters had significant disparities in the intakes of fruits, vegetables, junk food items, sugar, and fish.

    The study implies that implementing total and intermediate adherence to MedDiet patterns in non-Mediterranean teenagers might be a viable first step in nutrition and public health, with superior outcomes in brain health and academic attainment.

    A complete Mediterranean-style diet was associated with better academics and cognitive status than the Western diet.

  • Associations between food additive emulsifiers and cancer risk

    Associations between food additive emulsifiers and cancer risk

    In a recent study published in PLoS Medicine, researchers assessed associations between food emulsifier intake and cancer risk among NutriNet-Santé study participants.

    Background

    Emulsifiers, common in industrially processed foods, have been linked to chronic inflammation and an increased risk of cancer. These additives help stabilize lipid-containing food preparations, which account for a considerable amount of dietary energy consumption.

    Recent research shows that unfavorable consequences, such as changes in the gut microbiota and increased inflammation, may raise the risk of gut diseases and chronic diseases such as extraintestinal malignancies. Large-scale epidemiological studies are required to determine the long-term influence on human health.

    About the study

    In the present population-based prospective cohort study, researchers investigated whether consuming food additive emulsifiers increases cancer risk.

    The French NutriNet-Santé study involved 92,000 adult participants without prevalent cancer at recruitment, aged 45 years, and 79% female. They completed five questionnaires querying their dietary intake, health, anthropometric data, physical activity, sociodemographic data, and lifestyle data.

    The team followed the participants for seven years and estimated food additive emulsifier intakes for those with three or more 24-hour dietary records over two weeks during their initial two years of follow-up. They excluded individuals underreporting total calorie intake (17%, n=21,423).

    The researchers matched the food items consumed in specific dietary records against three databases to determine food additive presence: Observatoire de la qualité de l’alimentation (OQALI), Mintel Global New Products Database (GNPD), and Open Food Facts. They estimated the number of additives consumed based on ad hoc assays, generic food groups, and doses, following the European Food Safety Authority (EFSA) and Codex General Standard for Food Additives (GSFA) guidelines.

    Among food additive substances quantified from participant dietary records, the team identified 60 as emulsifying salts or emulsifiers and summed their intakes to determine the total food emulsifier exposure. They totaled individual emulsifier substances with those having identical chemical bonds into eight groups: lactylates, phosphates, polyglycerol ester molecules of fatty acids (FAs, monoglycerides, and diglycerides), carrageenans, celluloses, alginates, and modified starches.

    The researchers asked participants to report health occurrences on an online interface, verified by expert physicians after evaluating participant medical records and gathering additional data from hospitals and their treating doctors when required. They used the International Classification of Diseases, Clinical Modification Codes (ICD-CM, 10th revision) to classify cancers.

    The team conducted a study on primary cancer cases diagnosed two years after enrollment through 5 October 2021, using multivariable Cox regression modeling to determine the hazard ratios (HRs) for the association between food emulsifiers and cancer risk. They adjusted the model for factors such as age, sex, BMI, height, physical activity, smoking status, educational level, dietary records, family history of cancer, energy intake without alcohol, daily alcohol intake, lipids, sugars, sodium, fiber, consumption levels of fruits and vegetables, red and processed meats, and dairy products.

    Results

    The mean age of the study participants was 45 years. They provided six dietary records; on average, 99.8% of the study participants consumed one or more food emulsifiers. Compared to individuals with low emulsifiers, those with high intake were younger and showed a lower likelihood of smoking, lower alcohol intake, higher body mass index, educational attainment, physical exercise levels, dietary calorie intake, and ultra-processed food proportion in their diets.

    The team reported 2,604 new-onset cancer cases over two years of follow-up, including 90 lymphomas, 110 squamous cell carcinomas, 124 lung cancers, 162 melanomas, 207 colorectal, 322 prostate cancers, and 750 breast cancers. Increased monoglyceride and diglyceride fatty acid intake (especially E471) was related to higher cancer risk (hazard ratio, 1.2 for high versus low category), breast malignancy (HR, 1.2), and prostate tumors (HR, 1.5).

    Additionally, the team observed associations with the risk of breast cancer for increased total carrageenan intake (HR, 1.3) and E407 carrageenan consumption (HR, 1.3). They found no significant link between emulsifier intake and colorectal cancer incidence, and although they identified some links with other food emulsifiers, none were robust in the sensitivity analyses.

    The most common breast cancers were of the estrogen-positive (ER+, 85%) and progesterone-positive (PR+, 75%) types, while triple-negative breast cancers denoted 10% of all breast cancer cases. At diagnosis, 69.6% of breast cancers were local, 28.9% were advanced, and the remaining were metastatic. Regarding prostate cancers, 42%, 45%, and 13% were low-risk, intermediate-risk, and high-risk, respectively, as assessed using Gleason scores.

    Conclusion

    Overall, the study findings showed exposure to seven food emulsifiers was associated with an increased risk of cancer in French individuals. The findings may lead to changes in food industry laws on emulsifier use.

    The researchers also discovered links between greater consumption of carrageenans and fatty acid monoglycerides and diglycerides and overall prostate and breast cancer risk. To ensure consumer safety, public health officials advocate restricting cosmetic additive intake. Further research is required to replicate these findings in different populations.

  • Healthy lifestyles linked to specific metabolic markers, large study finds

    Healthy lifestyles linked to specific metabolic markers, large study finds

    [ad_1]

    In a recent study published in the journal Med, researchers used a collated dataset comprising four American sample cohorts to identify the metabolomic markers of a healthy lifestyle and, potentially, the mechanisms underlying their production. They used a combination of analytical techniques, particularly liquid chromatography-mass spectrometry, on the 13,056 datasets and observed that the healthy lifestyle metabolomic signature was largely reflective of lipid metabolism pathways.

    Shorter and more saturated di—and triacylglycerol metabolite sets were found to be inversely associated with healthy lifestyles, while phosphatidylcholine plasmalogens and cholesteryl esters were directly associated with the condition. Encouragingly, the relative concentrations of these biomarkers accounted for a 17% lower risk of all-cause mortality, a 19% reduced risk of cardiovascular disease-related mortality, a 17% lower risk of cancer-related mortality, and a 25% improved probability of attaining longevity.

    Study: Plasma metabolites of a healthy lifestyle in relation to mortality and longevity: Four prospective US cohort studies

    The relationship between lifestyle choices and metabolic health

    Chronic, non-transmissible disease prevalence is currently higher than it has ever been and has primarily been attributed to the increased adoption of sub-optimal health behavioral choices, including diets (e.g., the Western-style diet) and physical activity levels (e.g., the sedentary lifestyle). Previous research has highlighted the profound benefits of adopting a healthy lifestyle, with research on American cohorts revealing 55-71% reduced all-cause mortality risk in individuals who maintained their body mass index (BMI) between 18.5-24.9 kg/m2, consumed alcohol in moderation, partook in physical activity, and abstained from smoking.

    Unfortunately, the mechanisms underpinning these interactions remain largely unknown. Some studies have suggested that individuals’ health behavior components such as body weight, diet, alcohol consumption, physical activity, and smoking may have associated metabolomic signatures indicative of their current and historical health. Still, these hypotheses have rarely been tested within a scientific framework. The limited information in the field, despite being at times confounding, suggests that polyunsaturated fatty acids (PUFAs), phosphatidylcholines (PCs), and glutamate and similar amino acids (AAs) are associated with improved health outcomes, while triacylglycerols (TAG), sphingomyelins (SMs), and carnitines are associated with suboptimal ones.

    “However, most studies only examined diet and physical activity factors, with small sample sizes and limited sets of metabolites profiled. Thus, a comprehensive understanding of the metabolic pathways underlying healthy lifestyle behaviors remains to be discovered. By studying several modifiable lifestyle factors simultaneously, a better understanding of the common biological mechanisms as well as the key differences may be acquired.”

    About the study

    In the present study, researchers used lifestyle, metabolomic, and clinical information from four American cohorts comprising more than 13,000 individuals to compute a metabolomic-based combined healthy lifestyle score during mid-life and further examine the relationship between this score and mortality and longevity outcomes. Outcome follow-up was extensive and had a mean duration of 28 years. The cohorts included the Nurses’ Health Study (NHS; 1976), the second iteration of the same prospective cohort (NHSII; 1989), the Women’s Health Initiative (WHI; 1993), and the Health Professionals Follow-up Study (HPFS; 1986). They comprised primarily middle-aged (mean 54.3 years) women (85.8%) belonging to the White ethnicity (96.7%).

    Lifestyle information was participant-reported, clinical information was obtained from the prospective cohort database, and metabolomic information was derived from (fasting) blood plasma samples obtained at the time of study initiation and subsequent follow-up. Individuals lacking data on measured outcomes (BMI, alcohol consumption, metabolomic profiling, diets, physical activity levels, smoking status) were excluded. The WHI cohort was used as an external validation cohort for results obtained from the three remaining cohorts.

    Plasma metabolomic profiling was carried out using acetonitrile/methanol/formic acid extraction followed by hydrophilic interaction liquid chromatography (HILIC) and positive ionization mass spectrometry (MS) for polar compounds (e.g., amino acids) and isopropanol extraction followed by octyl high-performance liquid chromatography (HPLC) and positive ionization MS for lipids. The Metabolite Standard Initiative (MSI) database was used to identify obtained metabolites.

    Lifestyle factors (treatments) were of five main categories – diet, alcohol consumption, physical activity, smoking, and BMI, and were assessed using questionnaires and the Alternative Healthy Eating Index (AHEI). Mortality and longevity (outcomes) were obtained from family-member reports (for death), State statistics records, and the National Death Index database. Multivariable linear regressions, logistic regression, and elastic linear regressions were used for statistical data analyses. Cox proportional hazard ratios were computed to translate these results into relative disease risk.

    Study findings

    Results reveal that the metabolomic signature most reflective of healthy lifestyles is the lipid metabolism pathway comprising PC, TAG, CE, and DAG metabolite families. Diet composition and BMI were found to be the best predictors of positive metabolite signatures. Metabolite characterization identified more than 400 metabolites associated with lifestyle choices. Elastic regression analyses identified 187 of these metabolites as descriptive of healthy lifestyle behaviors – 58 were positively associated, while 129 were inversely associated with beneficial mortality and longevity outcomes.

    “…the MSEA revealed CEs, mainly of PUFAs, and PCs as the most enriched metabolite sets positively associated with a healthy lifestyle. CEs serve as a mean for the storage and transportation of cholesterol and other lipids in the blood and were shown to be reflective of dietary fat intake. PCs are naturally found in the body but also in foods such as eggs, fatty fish, and soybeans. They are well known for their essential role in cell membranes and membrane signaling.”

    Animo acids and metabolites involved in purine metabolism were also highlighted as signatures of healthy lifestyles. Vegetarian diets that are rich in circulating glycine, trigonelline, asparagine, hippurate, and glutamine and poor in valine, isoleucine, and leucine were found beneficial over dietary intakes of red meats, chicken, and energy drinks.

    Outcome analyses revealed a surprising fact – the metabolomic signatures identified herein were more accurate predictors of mortality and longevity than patient-reported fitness and health levels.  

    “Indeed, the metabolomic signature explained 38.0% of the association between the self-reported healthy lifestyle score and mortality, pointing to unique biological pathways captured by metabolomics. Consistent with the literature and with our mortality results, we found an association of the healthy lifestyle metabolomic signature with longevity, and the signature explained 48.6% of the association between self-reported healthy lifestyle score and longevity.”

    Conclusion

    The present study uses a large combined American cohort comprising more than 13,000 participants to identify metabolomic signatures associated with positive mortality and longevity outcomes as a consequence of healthy lifestyle and dietary choices. Study findings reveal that more than 100 metabolites are associated with (positive or negative) health lifestyle outcomes, most of which are involved in the lipid metabolism pathways.

    “…our findings suggest that greater adherence to a healthy lifestyle may lead to alterations in the metabolome that are associated with lower premature mortality risk and higher likelihood of longevity. We identified a metabolomic signature associated with a combined healthy lifestyle in US adults that is strongly reflective of lipid metabolism pathways. We found that those with a higher multimetabolite score had a lower risk of total and cause-specific mortality and a greater likelihood of living longer.”

  • Prenatal Mediterranean diet reduces offspring obesity

    Prenatal Mediterranean diet reduces offspring obesity

    [ad_1]

    In a recent study published in Nutrients, researchers determined the relationship between maternal Mediterranean diet (MedDiet) adherence during gestation and overweight or obese offspring risk at four years.

    Study: Close Adherence to a Mediterranean Diet during Pregnancy Decreases Childhood Overweight/Obesity: A Prospective Study. Image Credit: Marian Weyo/Shutterstock.comStudy: Close Adherence to a Mediterranean Diet during Pregnancy Decreases Childhood Overweight/Obesity: A Prospective Study. Image Credit: Marian Weyo/Shutterstock.com

    Background

    The childhood obesity epidemic is a global health concern affecting millions of children under five, causing psychological comorbidities, low self-esteem, behavioral and emotional disorders, and long-term cardiovascular morbidity and cancer.

    In addition, the World Health Organization’s (WHO) report emphasizes the importance of antenatal nutritional balance in preventing childhood obesity. 

    Close maternal adherence to a Mediterranean-style diet during gestation could be a promising strategy for determining potential obesity risks in childhood. Greater adherence to the diet has multiple health benefits for both mother and child.

    However, studies examining the impact of prenatal diet on offspring obesity are scarce and yield varied results, warranting further research.

    About the study

    In the present study, researchers investigated whether maternal MedDiet adherence was associated with offspring obesity at four years and evaluated the impact of maternal factors on the association.

    The team included 272 mother-child dyads from the Ensayo CLInico Para Suplementar con Hierro a EmbarazadaS (ECLIPSES) study for analysis.

    The primary study outcome was offspring overweight or obese based on sex- and age-specific body mass index (BMI) z-scores above the 85th percentile using the WHO child growth standards.

    The researchers obtained baseline maternal data from questionnaires during face-to-face interviews at recruitment, including medical history, age, educational level, socioeconomic status, physical activity, smoking status, and alcohol intake.

    In addition to the gestational age at birth and delivery type, they obtained data on child-related variables, including sex, length, and weight at birth.

    The team assessed prenatal diet using standardized 45-component food-frequency questionnaires (FFQs) at gestational weeks 12, 24, and 36 and calculated relative MedDiet (rMedDiet) scores. They measured offspring height and weight at four years.

    They estimated the total daily calorie intake using the REGAL food table and determined household socioeconomic status using the Catalan classification of occupations (CCO-2011).

    The researchers assessed physical exercise using the International Physical Activity Questionnaire (IPAQ) and categorized gestational weight gain (GWG) using the 2009 Institute of Medicine (IOM) recommendations.

    They performed multivariate logistic regression modeling to determine the odds ratios (OR) for the association between prenatal diet and childhood obesity.

    The ECLIPSES randomized clinical trial was conducted in Tarragona, Spain, from 2013 to 2017 to evaluate the efficacy of maternal iron supplementation in different dosages, adjusting for the initial hemoglobin levels during early gestation, on maternal iron status at the end of gestation.

    Primary care midwives recruited 791 expecting women aged ≥18 years for the study during the initial prenatal visit (before week 12 of gestation).

    Results

    The mean maternal age was 32; 70% were aged ≥30, and 42% were obese or overweight, with body mass index values ≥25 kg m-2.

    Most (86%) mothers were from Spain, 44% received university-level education, 22% had high socioeconomic status, and 17% practiced smoking during pregnancy. Among the mothers, 29% showed low MedDiet adherence, whereas 23% were highly adherent.

    The mean prenatal rMedDiet score was 9.80, and 26% of offspring were overweight or obese at four years, with a higher obesity prevalence among males (63%) than females (37%).

    The team found significant anthropometric differences (height, weight, and body mass index) by sex. The mean body mass index and body weight of offspring at four years were 16 kg m-2 and 18 kg, respectively.

    Males had higher weight (19 versus 17 kg), BMI (16 versus 15.6), weight-for-age z scores (0.5 versus 0.1), and body mass index z-scores (0.7 versus 0.2) than females.

    Overweight/obesity was less prevalent among offspring of mothers with university-level education, higher socioeconomic status, and higher gestational rMedDiet scores.

    After adjusting for potential confounding variables, the team found higher prenatal MedDiet adherence related to a reduced risk of offspring being overweight or obese (OR for the highest versus lowest quartile, 0.3).

    They obtained similar findings, stratifying by maternal age, early gestational BMI, educational attainment, smoking status, socioeconomic status, and GWG.

    After confounder adjustment, the team found that each point increase in the prenatal MedDiet was associated with a 19% lower risk of children being overweight or obese at four years (OR, 0.8).

    Smoking (OR, 2.5), pre-pregnancy overweight (OR, 2.5) or obesity (OR, 2.6), and excessive GWG (OR, 2.9) were considerably associated with offspring overweight or obese at four years.

    The protective effects of MedDiet on offspring weight were higher among expecting women aged below 30 years with overweight or obese during initial gestation, those who did not smoke, and those with low socioeconomic status.

    Conclusion

    Overall, the study findings showed higher prenatal MedDiet adherence associated with lower reduced offspring overweight/obesity at four years, especially among university-educated mothers aged below 30 years from low socioeconomic backgrounds who did not smoke. Future studies could investigate whether the association persists across life stages.

  • Early detection may help Kentucky tamp down its lung cancer crisis

    Early detection may help Kentucky tamp down its lung cancer crisis

    [ad_1]

    Anthony Stumbo’s heart sank after the doctor shared his mother’s chest X-ray.

    “I remember that drive home, bringing her back home, and we basically cried,” said the internal medicine physician, who had started practicing in eastern Kentucky near his childhood home shortly before his mother began feeling ill. “Nobody wants to get told they’ve got inoperable lung cancer. I cried because I knew what this meant for her.”

    Now Stumbo, whose mother died the following year, in 1997, is among a group of Kentucky clinicians and researchers determined to rewrite the script for other families by promoting training and boosting awareness about early detection in the state with the highest lung cancer death rate. For the past decade, Kentucky researchers have promoted lung cancer screening, first recommended by the U.S. Preventive Services Task Force in 2013. These days the Bluegrass State screens more residents who are at high risk of developing lung cancer than any state except Massachusetts — 10.6% of eligible residents in 2022, more than double the national rate of 4.5% — according to the most recent American Lung Association analysis.

    The effort has been driven by a research initiative called the Kentucky LEADS (Lung Cancer Education, Awareness, Detection, and Survivorship) Collaborative, which in 2014 launched to improve screening and prevention, to identify more tumors earlier, when survival odds are far better. The group has worked with clinicians and hospital administrators statewide to boost screening rates both in urban areas and regions far removed from academic medical centers, such as rural Appalachia. But, a decade into the program, the researchers face an ongoing challenge as they encourage more people to get tested, namely the fear and stigma that swirl around smoking and lung cancer.

    Lung cancer kills more Americans than any other malignancy, and the death rates are worst in a swath of states including Kentucky and its neighbors Tennessee and West Virginia, and stretching south to Mississippi and Louisiana, according to data from the Centers for Disease Control and Prevention.

    It’s a bit early to see the impact on lung cancer deaths because people may still live for years with a malignancy, LEADS researchers said. Plus, treatment improvements and other factors may also help reduce death rates along with increased screening. Still, data already shows that more cancers in Kentucky are being detected before they become advanced, and thus more difficult to treat, they said. Of total lung cancer cases statewide, the percentage of advanced cases — defined as cancers that had spread to the lymph nodes or beyond — hovered near 81% between 2000 and 2014, according to Kentucky Cancer Registry data. By 2020, that number had declined to 72%, according to the most recent data available.

    “We are changing the story of families. And there is hope where there has not been hope before,” said Jennifer Knight, a LEADS principal investigator.

    Older adults in their 60s and 70s can hold a particularly bleak view of their mortality odds, given what their loved ones experienced before screening became available, said Ashley Shemwell, a nurse navigator for the lung cancer screening program at Owensboro Health, a nonprofit health system that serves Kentucky and Indiana.

    “A lot of them will say, ‘It doesn’t matter if I get lung cancer or not because it’s going to kill me. So I don’t want to know,’” said Shemwell. “With that generation, they saw a lot of lung cancers and a lot of deaths. And it was terrible deaths because they were stage 4 lung cancers.” But she reminds them that lung cancer is much more treatable if caught before it spreads.

    The collaborative works with several partners, including the University of Kentucky, the University of Louisville, and GO2 for Lung Cancer, and has received grant funding from the Bristol Myers Squibb Foundation. Leaders have provided training and other support to 10 hospital-based screening programs, including a stipend to pay for resources such as educational materials or a nurse navigator, Knight said. In 2022, state lawmakers established a statewide lung cancer screening program based in part on the group’s work.

    Jacob Sands, a lung cancer physician at Boston’s Dana-Farber Cancer Institute, credits the LEADS collaborative with encouraging patients to return for annual screening and follow-up testing for any suspicious nodules. “What the Kentucky LEADS program is doing is fantastic, and that is how you really move the needle in implementing lung screening on a larger scale,” said Sands, who isn’t affiliated with the Kentucky program and serves as a volunteer spokesperson for the American Lung Association.

    In 2014, Kentucky expanded Medicaid, increasing the number of lower-income people who qualified for lung cancer screening and any related treatment. Adults 50 to 80 years old are advised to get a CT scan every year if they have accumulated at least 20 pack years and still smoke or have quit within the past 15 years, according to the latest task force recommendation, which widened the pool of eligible adults. (To calculate pack years, multiply the packs of cigarettes smoked daily by years of smoking.) The lung association offers an online quiz, called “Saved By The Scan,” to figure out likely eligibility for insurance coverage.

    Half of U.S. patients aren’t diagnosed until their cancer has spread beyond the lungs and lymph nodes to elsewhere in the body. By then, the five-year survival rate is 8.2%.

    But regular screening boosts those odds. When a CT scan detects lung cancer early, patients have an 81% chance of living at least 20 years, according to data published in November in the journal Radiology.

    Some adults, like Lisa Ayers, didn’t realize lung cancer screening was an option. Her family doctor recommended a CT scan last year after she reported breathing difficulties. Ayers, who lives in Ohio near the Kentucky border, got screened at UK King’s Daughters, a hospital in far eastern Kentucky. The scan didn’t take much time, and she didn’t have to undress, the 57-year-old said. “It took me longer to park,” she quipped.

    She was diagnosed with a lung carcinoid tumor, a type of neuroendocrine cancer that can grow in various parts of the body. Her cancer was considered too risky for surgery, Ayers said. A biopsy showed the cancer was slow-growing, and her doctors said they would monitor it closely.

    Ayers, a lifelong smoker, recalled her doctor said that her type of cancer isn’t typically linked to smoking. But she quit anyway, feeling like she’d been given a second chance to avoid developing a smoking-related cancer. “It was a big wake-up call for me.”

    Adults with a smoking history often report being treated poorly by medical professionals, said Jamie Studts, a health psychologist and a LEADS principal investigator, who has been involved with the research from the start. The goal is to avoid stigmatizing people and instead to build rapport, meeting them where they are that day, he said.

    “If someone tells us that they’re not ready to quit smoking but they want to have lung cancer screening, awesome; we’d love to help,” Studts said. “You know what? You actually develop a relationship with an individual by accepting, ‘No.’”

    Nationally, screening rates vary widely. Massachusetts reaches 11.9% of eligible residents, while California ranks last, screening just 0.7%, according to the lung association analysis.

    That data likely doesn’t capture all California screenings, as it may not include CT scans done through large managed care organizations, said Raquel Arias, a Los Angeles-based associate director of state partnerships at the American Cancer Society. She cited other 2022 data for California, looking at lung cancer screening for eligible Medicare fee-for-service patients, which found a screening rate of 1%-2% in that population.

    But, Arias said, the state’s effort is “nowhere near what it needs to be.”

    The low smoking rate in California, along with its image as a healthy state, “seems to have come with the unintended consequence of further stigmatizing people who smoke,” said Arias, citing one of the findings from a 2022 report looking at lung cancer screening barriers. For instance, eligible patients may be reluctant to share prior smoking habits with their health provider, she said.

    Meanwhile, Kentucky screening efforts progress, scan by scan.

    At Appalachian Regional Healthcare, 3,071 patients were screened in 2023, compared with 372 in 2017. “We’re just scratching the surface of the potential lives that we can have an effect on,” said Stumbo, a lung cancer screening champion at the health system, which includes 14 hospitals, most located in eastern Kentucky.

    The doctor hasn’t shed his own grief about what his family missed after his mother died at age 51, long before annual screening was recommended. “Knowing that my children were born, and never knowing their grandmother,” he said, “just how sad is that?”

  • Smoking, infection, and BMI found to significantly sway immune response, study shows

    Smoking, infection, and BMI found to significantly sway immune response, study shows

    [ad_1]

    In a recent study published in the journal Nature, researchers explored the factors influencing cytokine release, a critical component of the host immunological response.

    The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic emphasized the wide variation in immunological responses between populations, with age, sex, and genetic variables all playing vital roles. However, therapy and vaccine development often disregard immunological diversity. The Milieu Intérieur research project has contributed to understanding immune homeostasis by quantitatively evaluating the impacts of age, gender, cellular composition, and genetics on immune-related gene transcript levels and those of age, gender, smoking, and cytomegalovirus (CMV) infections on leukocyte distribution in blood. Further study might help us better understand the elements that influence immune responses and how they affect clinical outcomes.

    About the study

    In the present study, researchers investigated environmental variables associated with cytokine responsiveness to immunological activation.

    The team measured the levels of several cytokines [C‐X‐C motif chemokine ligand 5 (CXCL5), colony-stimulating factor 2 (CSF2), interferon-gamma (IFNγ), interleukin-1 beta (IL-1β), IL-2, 6, 8, 10, 12p70, 13, 17, 23, and tumor necrosis factor (TNF)] after 22 hours of whole-blood stimulations with 11 immunological agonists for 1,000 Milieu Intérieur project donors and in an unstimulated (control) condition. They categorized the stimulations as microbial, viral, T-lymphocyte activated, and cytokines.

    Heat maps and principal component analyses (PCA) of 13 cytokine molecules investigated in 12 immunological stimulations revealed the individual cytokines generated by every independent condition. The team performed hierarchical clustering evaluations of log mean variations in cytokine levels to identify groups corresponding to stimulation types.

    The researchers compiled 136 environmental, socio-demographic, nutritional, and clinical variables from the digital case report forms and tested for their relationships with cytokines induced in every stimulation using likelihood ratio tests (LRTs) with age, experimental batch, and gender as covariates. They also investigated human leukocyte antigen (HLA) as a predictor of immune response variability, particularly in antigen-specific responses. The team investigated whether smoking-cytokine correlations continued when particular subsets of circulating immune cells were included in their models, as these cells are related to cytokine elevations. They evaluated the biological impact of smoking on cytokine production, calculating the effect sizes for the smoking variables in the linear models and assessing the influence of 326 soluble proteins in sera obtained from 400 donors.

    The researchers investigated whether epigenetic pathways contribute to the impact of smoking on adaptive immune responses. They analyzed deoxyribonucleic acid (DNA) methylation at more than 850,000 CpG sites and investigated whether the levels may explain the association between smoking and cytokine levels following SEB stimulation. The study was especially well-suited to identifying response protein quantitative trait loci (pQTLs) since it tested 5,699,237 high-quality imputed single nucleotide polymorphisms (SNPs) for relationships with the cytokines elicited by each stimulation.

    Results

    The team identified smoking, CMV latent infection, and body mass index (BMI) as the most significant drivers of cytokine response variability. Smoking impacts innate and adaptive immune responses, with the influence on innate responses diminishing after quitting and associated with serum carcinoembryonic antigen-related cell adhesion molecule 6 (CEACAM6) levels. However, the impact on adaptive responses lasts long after smoking cessation and is associated with epigenetic memory.

    The study highlighted eleven factors related to one or more cytokines in the immune stimulations, with BMI being the most prevalent. Smoking-related factors were related to interleukin-2 and interleukin-13 (adaptive immunity) in Staphylococcus aureus enterotoxin B superantigen (SEB), anti-cluster of differentiation 3 (anti-CD3) and anti-CD28 immune stimulations, and CXCL5 following Escherichia coli infections or innate immunological stimulations. The findings indicate that smoking causes inflammation and reduces immunity against bacterial infections.

    Cytomegalovirus latent infection was associated with TNF, CSF2, and IFNγ cytokines secreted by adaptive immune cells. BMI-related factors were related to CXCL5 following Bacillus Calmette-Guérin (BCG) immune stimulation, and interleukin-2 following SEB stimulation demonstrated obesity dysregulation. The team found no significant association between major histocompatibility complex (MH) class II, DQ beta 1, and HLA.DBQ1.1P, and IL-6 in the control condition.

    The study found 2,416 CpG locations related to smoking in the Milieu Intérieur sample, with 129 significantly associated with IL-2 in SEB stimulation. However, 11 CpGs abolished the relationship between smoking and IL-2 and IL-13. Current smokers had lower DNA methylation than non-smokers, but former smokers had an intermediate methylation level. The number of years smoked, total cigarettes smoked, and IL-2 levels in SEB stimulation were adversely linked with DNA methylation, although the number of years after smoking typically correlated positively.

    Overall, the study findings identified three novel factors, i.e., smoking status, CMV latent infection, and BMI, associated with variability in cytokine secretion following immunological stimulation. These characteristics may have clinical consequences for the risk of contracting infections, cancer, or autoimmune diseases. Smokers have a heightened inflammatory response after bacterial activation, which promptly decreases after quitting. However, the impacts on adaptive immunity last for years after stopping. The link between smoking and long-lived B and T cell subsets and DNA methylation offers a potential for long-term consequences in the adaptive response.

  • Research uncovers link between reproductive factors and COPD risk in women

    Research uncovers link between reproductive factors and COPD risk in women

    [ad_1]

    A range of reproductive factors, including age when periods first start and an early menopause, are all linked to a heightened risk of COPD—the umbrella term for progressive lung conditions that cause breathing difficulties—finds research published online in the journal Thorax.

    Miscarriage, stillbirth, infertility, and having 3 or more children are also associated with a heightened risk of COPD, which includes emphysema and chronic bronchitis, the findings show.

    Recent evidence indicates substantial gender  differences in susceptibility to, and severity of, COPD, note the researchers. Women seem to develop severe COPD at younger ages than men. And while smoking is a major risk factor, non-smokers with COPD are more likely to be women, they add.

    Previously published studies looking at the potential influence of female hormones on COPD risk have been hampered by methodological flaws, note the researchers. To try and get round these issues, they drew on the International Collaboration for a Life Course Approach to Reproductive Health and Chronic Disease Events (InterLACE) consortium.

    This is a collection of 27 observational studies, pooling individual level data from more than 850,000 women in 12 countries.

    For the purposes of the current study, the researchers included three groups of women (283,070; average age 54) with data on reproductive factors and COPD: the Australian Longitudinal Study on Women’s Health 1946-51 (ALSWH-mid); the UK Biobank; and the Swedish Women’s Lifestyle and Health Study (WLH).

    In the ALSWH-mid and UK Biobank groups, women were tracked until the end of December 2019. Women in WLH were tracked up to the end of 2010.

    Information on reproductive factors was collected at study entry or at subsequent data collection points, along with potentially influential factors: birth year (before or after 1950), ethnicity, educational level, duration of smoking, asthma (never and ever), and weight (BMI).

    COPD was retrospectively and prospectively identified through self-report and medical records, which included prescriptions, hospital admissions, emergency care visits, and death registry data.

    The women’s health was monitored for an average of 11 years. During this time, 10,737 (4%) women developed COPD at an average age of 63. 

    Women with COPD were more likely to be older when recruited to their studies, to have fewer than 10 years of formal education, to be obese, to have smoked for at least 10 years, and to have asthma-all risk factors for the condition. Some 53, 205 (16%) women were excluded because of missing data.

    Several reproductive factors were associated with the risk of COPD, including age when periods first started; number of children; a history of infertility, miscarriage or stillbirth, especially multiple miscarriages or stillbirths; and age at menopause.

    A U-shaped pattern emerged for the age at which periods first started. Those who began menstruating before or at the age of 11 were 17% more likely to develop COPD than those who did so at the age of 13; after the age of 16, the risk was 24% higher.

    Women with children were at higher risk of COPD than childless women. Compared with having 2 children, more than 3 was associated with a 34% higher risk, while women with one child were at 18% higher risk.

    Women who experienced infertility also had a 13% higher risk of COPD than women who were fertile. 

    And among those who had ever been pregnant, a history of miscarriage was associated with a 15% higher risk of COPD, with the risk rising in tandem with the number of miscarriages: 28% higher for 2; and 36% higher for 3 or more.

    Similarly, stillbirth was associated with a 42% overall higher risk of COPD, with the risk rising in tandem with the number of stillbirths.

    Menopause before the age of 40 was associated with a 69% higher risk, compared with those experiencing it naturally at the age of 50-51, while the risk was 21% lower for those who went through it at or after the age of 54.

    This is an observational study, so can’t establish cause, and the researchers acknowledge various limitations to their findings, including potentially influential factors. 

    For example, they had no detailed information on hormonal contraception and HRT use, and data on parental history of COPD, childhood respiratory infections, secondhand smoking or occupational exposures, weren’t available for all 3 of the groups. 

    But by way of an explanation for their findings, they suggest that the female hormone estrogen is likely to have a key role in COPD risk in women, because of its various effects on the lung. 

    “The overall effect of estrogen might differ depending on the timing,” they suggest. “In the early or middle reproductive stage, long or higher accumulated exposure to estrogen would be detrimental to the lung, leading to a higher risk of COPD among women with early menarche or multiple live births. 

    “In the later stage, estrogen may be protective, since earlier age at menopause or [ovary removal] (indicates shorter exposure to estrogen) were associated with a higher risk of COPD.” 

    Other factors, including autoimmune disease, such as type 1 diabetes, and social and environmental factors, such as air pollution, underweight, and socioeconomic deprivation, might also be influential, they add.

  • Smoking Alters Your Immune System for Years After You Quit

    Smoking Alters Your Immune System for Years After You Quit

    [ad_1]

    To figure out why and how the effect lasts for years after someone smokes their last cigarette, Duffy’s team turned to their donors’ DNA. Seemingly everything from wildfire smoke to your parents’ trauma has been linked to epigenetic changes—physical manipulations of the DNA molecule that switch genes on or off. Sure enough, the long-term effect of smoking on the immune response also appears to be linked to epigenetics.

    Duffy admits that interpreting these effects can get weird. It’s tempting to think of the more reactive immune system seen in smokers as “good”—when you’re injured or sick, short-term inflammation helps your body heal. But an overblown response that lingers once the threat is gone can lead to chronic inflammation or autoimmune disease.

    Giving up smoking brings the inflammatory response back to where it would have been without cigarettes, but smoking-related epigenetic changes may be tougher to reverse, suspects Sheena Cruickshank, an immunologist at the University of Manchester. The affected immune cells are long-lived, sticking around in the bloodstream for years. Ex-smokers may have to carry traces of their past cigarettes with them until those cells die.

    Of course, smoking behavior doesn’t happen in a vacuum. All 1,000 donors in this study live widely varied lives shaped by a dizzying number of things beyond cigarettes. “We’re exposed to so many different things that it’s difficult to tease them apart,” says Adam Lacy-Hulbert, an immunologist at the Benaroya Research Institute in Seattle, Washington. This study corrected for age and sex, but that certainly doesn’t account for everything. Cruickshank says that, while the effect of any individual environmental factor—smoking included—may be modest, these effects can pile on top of each other and lead to big changes to the immune system.

    These results may have important implications for vaccine delivery. We already tailor vaccine recommendations to specific age groups because inflammation is known to increase as we get older (immunologists even have a term for this: “inflammaging”). Lacy-Hulbert wonders whether we ought to consider environmental factors like people’s smoking habits (past and present) when planning the timing or formulation of their vaccinations. “Immune age, like regular old age, just marches on—things get worse and worse over time,” Lacy-Hulbert says. If smoking is associated with roughly the same degree of change to the immune response as aging, he speculates, “You might imagine that smoking could add years to your immunological age.”

    Duffy and his colleagues at the Milieu Intérieur project already have multiple follow-up projects underway, gathering data from donors in Africa and Asia as well as from children and adults over 75 years old. They’re also preparing a 10-year follow-up report with 415 of the original 1,000 donors sampled in the Nature study to see how changes to their lifestyle affected their immune response over that decade. Moving forward, Tsang hopes that future studies run specific experiments to test some of these associations in the lab, to dig into how our environment and behavior shapes our immune system.

    In the meantime, Cruickshank says, the best way to keep your immune system healthy is to follow the basic advice you’ve probably been told a thousand times: eat a varied, minimally processed diet; move your body; destress; and get plenty of sleep. “In terms of being healthy, smoking is probably the worst thing you can do,” Duffy adds.

    While we still don’t know exactly how long-lived the impact of smoking is, or whether it can be reversed, there’s some good news: After quitting, the effect of smoking on the immune response seems to fade with time. “The best time to stop smoking is now,” Duffy says. “It’s always a good time.”

  • Managing migraines and menopausal symptoms to reduce cardiovascular risks in middle-aged women

    Managing migraines and menopausal symptoms to reduce cardiovascular risks in middle-aged women

    [ad_1]

    For middle-aged women plagued by migraines, or hot flashes and night sweats, another worry may linger in the backs of their minds: whether these experiences have set them up for a heart attack, a stroke or another cardiovascular crisis.

    After all, past research suggesting such a link during and after menopause has gotten a lot of attention.

    But a pair of new studies in the journal Menopause suggest that most of them don’t need to worry as much, especially if they don’t have both migraines and long-term hot flashes and night sweats.

    Instead, they should focus on tackling the other factors that can raise their cardiovascular risk by getting more sleep, exercise and healthy foods, quitting tobacco, and minding their blood pressure, blood sugar, cholesterol and weight.

    For women who have experienced both migraines and hot flashes or night sweats over many years, one of the new studies does suggest an extra level of cardiovascular risk. That makes heart disease and stroke prevention even more important in this group, says study leader Catherine Kim, M.D., M.P.H., of the University of Michigan.

    And for women currently in their 20s and 30s who experience migraines, the new research suggests that they might be heading for a higher risk of long-term menopause-related symptoms when they get older.

    Long-term study yields important insights

    Kim and her colleagues at Michigan Medicine, U-M’s academic medical center, published the new pair of studies based on an in-depth analysis of data from a long-term study of more than 1,900 women who volunteered to have regular physical exams and blood tests, and to take yearly health surveys, when they were in their late teens to early 30s.

    Those women, now in their 50s and 60s, have provided researchers with a priceless view of what factors shape health in the years leading up to menopause and beyond, through their continued participation in the CARDIA study.

    “The anxiety and dread that women with migraines and menopausal symptoms feel about cardiovascular risk is real – but these findings suggest that focusing on prevention, and correcting unhealthy habits and risk factors, could help most women,” said Kim, who is an associate professor of internal medicine at U-M and a primary care physician.

    “For the subgroup with both migraines and early persistent hot flashes and night sweats, and for those currently experiencing migraines in their early adulthood, these findings point to an added need to control risks, and address symptoms early,” she adds.

    Just over 30% of the middle-aged women in the study reported they had persistent hot flashes and night sweats, which together are called vasomotor symptoms or VMS because they relate to changes in the diameter of blood vessels.

    Of them, 23% had reported also having migraines. This was the only group for whom Kim and her colleagues found extra risk of stroke, heart attack or other cardiovascular events that couldn’t be explained by other risk factors that have long been known to be linked to cardiovascular problems.

    In addition to those with persistent vasomotor symptoms starting in their 40s or before, 43% of the women in the study had minimal levels of such symptoms in their 50s, and 27% experienced an increase in VMS over time into their 50s and early 60s.

    The latter two groups had no excess cardiovascular risk once their other risk factors were taken into account, whether or not they had migraines. Use of hormone-based birth control and estrogen to address medical issues did not affect this risk.

    Controlling destiny

    In the study of data from the same women in their earlier stages of life, the researchers found that the biggest factors in predicting which ones would go on to have persistent hot flashes and night sweats were having migraines, having depression, and smoking cigarettes, as well as being Black or having less than a high school education.

    These two studies, taken together, underscore that not all women have the same experiences as they grow older, and that many can control the risk factors that might raise their chances of heart disease and stroke later in life. In other words, women can do a lot to control their destiny when it comes to both menopause symptoms and cardiovascular diseases.”


    Catherine Kim, M.D., M.P.H., University of Michigan

    She notes that the American Heart Association calls these risk factors the “Essential 8” and offers guides for what women, men and even children and teens can do to address them.

    Evolving knowledge and treatment

    The long-term study that the two new findings come from was specifically designed to look at cardiovascular risks when it launched in the mid-1980s. CARDIA stands for Coronary Artery Risk Development in Young Adults.

    Back in the 80s, knowledge about the biology of blood vessels, down to the cellular and molecular level, was nowhere near where it is today. Both vasomotor symptoms in menopause and migraines have to do with blood vessel contraction and dilation.

    But decades of research has shown the microscopic impacts on blood vessels of years of smoking, poor sleep, poor eating habits and lack of activity, as well as a person’s genetic inheritance, life experiences and hormonal history.

    Newer injectable migraine medications called calcitonin gene-related peptide (CGRP) antagonists have reached the market in recent years.

    Using monoclonal antibodies, they target a key receptor on the surface of blood vessel cells to prevent migraines and cluster headaches. But they are expensive and not covered by insurance for all people with migraines.

    While the new study is based on data from years before these medications became available, Kim said she recommends them to her patients with persistent migraines, as well as working with them to understand what triggers their migraines and how to use other medications including pain relievers and antiseizure medications to prevent them.

    She also notes that the paper on future risk of persistent hot flashes and night sweats echoes the recent trend of using antidepressant medications to try to ease these menopause effects.

    Kim also says that evidence has grown about the importance of healthy sleep habits for reducing hot flashes, as well the short-term use of estradiol-based hormone therapy patches, which have not been shown to have a link to cardiovascular risk. And, she notes that research has not shown any over-the-counter supplement or herbal remedy to be effective, and that these are far less regulated than medications.
