Under the right living arrangement, disease-resistant corals can help “rescue” corals that are more vulnerable to disease, found a study from the University of California, Davis, that monitored a disease outbreak at a coral nursery in Little Cayman, Cayman Islands. 

The study, published in the journal Scientific Reports, found that when people grow corals of the same genotype — or genetic makeup — together, those corals are more vulnerable to disease than corals that grow among a mixture of genotypes. The study further found that some vulnerable corals can be “rescued” by resistant genotypes.

“We saw that some corals were more resistant to disease just by being around other corals that were particularly resistant,” said lead author Anya Brown, an assistant professor at the UC Davis Bodega Marine Laboratory in the Department of Evolution and Ecology. “Proximity to these resistant genotypes helped buffer the susceptible corals from the effects of the disease.”

The findings provide further evidence that genetic diversity can help reduce disease transmission among corals, while also showing that it’s important to consider how corals are arranged in nurseries and reef restoration projects to prevent the spread of disease.

Coral exam

After an outbreak of white band disease spread through its coral nursery in Little Cayman, the nonprofit Central Caribbean Marine Institute worked together with the study’s academic authors to monitor its population of endangered Caribbean staghorn coral, A. cervicornis.

Before the outbreak, the nursery had attached coral fragments to plastic PVC frames to propagate them. Some frames held coral from a single donor colony. Other frames hosted corals from multiple donor colonies representing a mixture of genotypes.

After tracking the presence of the disease across 650 coral fragments for more than five months, the researchers found that corals living on frames with a mixture of genotypes were substantially more resistant to white band disease, a devastating bacterial disease that nearly wiped out A. cervicornis in the 1980s.

Diversity and disease resistance

The ability of resistant coral to help protect vulnerable individuals is similar to how vaccinations work among humans: Vaccinated individuals resist a disease, erecting a barrier that weakens its ability to move through them and on to the next susceptible person. 

As for the genetic diversity piece, agricultural lands provide another comparison: Monocrops, where the same crop is planted in the same place each year, tend to be more susceptible to disease than diverse systems. This research suggests a similar dynamic is at play among the ocean’s coral reefs.

An ideal arrangement

Brown hopes these concepts and this study will be integrated into coral nursery and reef restoration projects.

“I hope people working with coral nurseries use this as a springboard to see how this influences the spread of disease,” Brown said. “Nurseries that intentionally arrange corals with mixtures of genotypes can help corals vulnerable to disease thrive. This can help build coral resilience by repopulating reefs with a diverse genetic mixture of corals.”

The study’s co-authors include Dagny-Elise Anastasiou, Sophia MacVittie and Carrie Manfrino of Central Caribbean Marine Institute; Monica Schul, Lindsay Spiers and Julie Meyer of University of Florida; and Thomas Frazer of University of South Florida.

The study was financially supported by the John H. and Katherine C. Ewel Fellowship, the University of Florida and the Central Caribbean Marine Institute.

1. Internal medicine physicians call for improved access and quality in health care for incarcerated patients
Abstract: https://www.acpjournals.org/doi/10.7326/M22-2370

Note: Sound bites from ACP President Ryan Mire, MD, MACP available for download at https://www.dssimon.com/MM/ACP-Incarceration
Adequately funded policies and procedures are needed to reduce health care disparities in access to, and quality of, health care for the U.S. jail and prison population says the American College of Physicians (ACP). Health Care During Incarceration: A Policy Position Paper of the American College of Physicians details recommendations to improve the health and wellbeing of individuals incarcerated in adult correctional facilities. The paper is published in Annals of Internal Medicine.

ACP’s recommendations include adequate funding for, and timely access to, necessary health care services that are evidence-based and meet community standards. They also recommend measures to ensure adequate nutrition; opportunity for physical activity; smoke-free policies and smoking cessation interventions; and access to recommended preventive health services. ACP further calls for policies to adequately treat both chronic noncommunicable diseases and infectious diseases. This should include infectious disease prevention and control programs developed with public health authorities. In addition, all persons entering correctional facilities should be screened for substance use disorders and behavioral health conditions and provided with treatment if necessary. ACP also supports policies that promote the treatment of patients with substance use disorders as an alternative incarceration.

The paper also details recommendations for population segments within correctional facilities. This includes recommendations for how to better meet the needs of incarcerated women; LGBTQ+ patients; aging patients and those living with disabilities or life-limiting illnesses; and immigrant populations.

Lastly, the paper details how health care needs must be included in community re-entry planning for individuals who are released from jail or prison, so that they are able to continue to access health care and social services once they return to their communities. ACP specifically makes recommends for policies that would help to facilitate or reinstate state Medicaid enrollment.

2. Climate change contributing to an expected rise in fungal pathogens over the next decade
Abstracthttps://www.acpjournals.org/doi/10.7326/M22-2371
URL goes live when the embargo lifts
Endemic mycoses, or fungal pathogens that lead to a wide range of diseases in humans, are expected to become more common in the coming decade, partly due to climate change. The increasing spread of these pathogens increases the possibility that clinicians without familiarity of the mycoses may encounter them in daily practice. This is important because endemic mycoses may be erroneously diagnosed as bacterial infections, leading to inappropriate use of antibiotics and other prescriptions that provide no relief to the patient. The commentary is published in Annals of Internal Medicine.

Stopping the spread of fungal pathogens is a public health priority being increasingly recognized by international public health efforts. In October 2022, the World Health Organization (WHO) announced the creation of the WHO fungal priority pathogens list (WHO FPPL), a new effort to “systematically prioritize fungal pathogens, considering their unmet research and development (R&D) needs and perceived public health importance.”

Authors from the University of California-Davis and the Centers for Disease Control and Prevention highlight the increasing spread of blastomycosis, coccidioidomycosis, and histoplasmosis, the endemic mycoses that are most prevalent in North America. All three pathogens have been traced outside of their original endemic regions due to both climate change and more thorough identification. The authors highlight the current lack of guidelines for testing and treatment of mycoses, unlike when clinicians encounter infections like community-acquired pneumonia. Patients who have been infected with these pathogens may experience long periods of illness between initial infection and diagnosis, leading to increased healthcare costs and frequent antibiotic overprescription. The authors say that improvements in our epidemiologic understanding of disease and the ability to capture changes in disease incidence at the county level would enable directed educational efforts, public health campaigns, and quality improvement initiatives to reduce the time to diagnosis and receipt of appropriate antifungal therapy.

3. More than half of pivotal FDA trials recruit from lower middle income countries, but country enrollment is rarely reported
Abstract: https://www.acpjournals.org/doi/10.7326/M22-1857
URL goes live when the embargo lifts
An analysis of 144 pivotal trials for U.S. Food and Drug Administration (FDA)-approved medications in cancer, cardiovascular disease, and neurology has found that more than half of the studies recruit patients from low- and middle-income countries (LMIC). However, available country data for trials are sparse, contributing to problems with both study verification and participant recruitment ethics. The analysis is published in Annals of Internal Medicine.

Drugs sold in North America are often tested abroad, including LMICs. Recruitment from LMICs for trials intended to inform North American health care has scientific and ethical implications. Drug effects can vary because of geographic differences in patient baseline characteristics, diet, and comorbid conditions. Recruitment in LMICs also raises ethical issues. Trials require extra clinic visits, procedures, and exposure to unproven treatments, including unknown risks. The FDA does not require sponsors to report or publicly disclose which countries participants are recruited from.

Researchers from the Department of Equity, Ethics and Policy, McGill University, conducted a cross-sectional analysis of 66 new drugs and 144 pivotal clinical trials. The authors evaluated 29 approved cardiovascular trials, 26 approved neurologic trials, and 61 approved cancer trials. They found that among all analyzed trials, 56 percent in cancer, 79 percent in cardiovascular disease, and 56 percent in neurology recruited from LMICs. The authors also report that country-level enrollment figures were not available for 55 percent of multi-country trials. According to the authors, although recruitment is often reported by region or continent, such groupings can obscure important differences among host countries. They emphasize that sporadic availability of country enrollment can frustrate the valid interpretation of pivotal trial findings. It can also limit the ability to monitor and hold research sponsors accountable for fair participant selection. They urge journals, regulators, and ClinicalTrials.gov to establish policies that require public reporting of country-level information on recruitment.

Physicians urged to consider fungal infections as possible cause for lung inflammation

Climate change widens spread of Valley fever, other fungal diseases beyond typical hot spots

Peer-Reviewed Publication

UNIVERSITY OF CALIFORNIA - DAVIS HEALTH

Infectious diseases expert George Thompson has been studying and treating fungal diseases for over two decades. He monitors their spread, symptoms and relative risks. Lately, he has been more concerned about a rising threat:  the spread of disease-causing fungi outside of their traditional hot spots.

In a commentary published in Annals of Internal Medicine, Thompson and his co-author from the Mycotic Diseases Branch at the Centers for Disease Control and Prevention Tom Chiller raised the alarm. They noted the expanding presence and emerging risks from three endemic fungal diseases: histoplasmosis, blastomycosis and coccidioidomycosis (Valley fever).

“These three fungal diseases usually inhabit specific U.S. regions conducive to their survival,” said Thompson. He is a professor at the UC Davis School of Medicine in the Department of Internal Medicine, Division of Infectious Diseases, and the Department of Medical Microbiology and Immunology. “Recently, we are finding more cases of these diseases outside their known areas, taking clinicians and patients by surprise.”

Fungal infections are an emerging global threat

Fungi are microorganisms found abundantly in nature. They include yeasts, molds, mushrooms and more. While most fungi are harmless to humans, some can cause diseases (known as mycoses) that could wreak havoc on patients and the health system.

Recently, the World Health Organization (WHO) released its fungal priority pathogens list, identifying the most concerning fungi that can cause infections for which drug resistance or other treatment challenges exist. These pathogens are projected to lead to even more problems over the next decade.

Climate change increasing spread of fungal infections

Endemic fungi have traditionally had distinct geographic distributions. Climate changes in temperature and rain are affecting where these fungi thrive.

The authors noted the expanding regions hosting the endemic fungi. Valley fever, for example, was found in Nebraska, way east of its traditional hot spots in California and Arizona.

“The organisms are probably much more widespread than we originally thought. There is an increasing likelihood that clinicians who are not familiar with these organisms will encounter them during their daily practice,” Thompson said.

Clinicians commonly miss fungal infection diagnosis

The three endemic mycoses have many symptoms, including fever, chills, cough, night sweats and fatigue. They may also cause lung infections that mimic pneumonia. As such, they can easily be mistaken for more common viral and bacterial lung infections.

Current guidelines on pneumonia from the American Thoracic Society and the Infectious Diseases Society of America do not offer specific testing or treatment recommendations for endemic mycosis. Most practitioners may have little experience in the recognition and treatment of these fungal lung infections.

About 20% of pneumonia cases in some parts of California and Arizona are caused by Valley fever. Yet, it usually takes more than three weeks after symptoms start to get the right diagnosis. It might take even longer to diagnose histoplasmosis and blastomycosis.

Fungal infections are also commonly misdiagnosed as bacterial. When this misdiagnosis happens, the patient is prescribed antibiotics that are ineffective for fungal diseases. This also exposes them to unneeded medications and contributes to the rise of antimicrobial resistance in the community. The authors urged physicians to take a thorough travel history and run more testing to rule out fungal infection before giving patients a second round of antibiotics.

“In regions where these fungal diseases flourish, doctors need to consider the diagnosis and testing for mycoses in all patients with suggestive illness,” Thompson recommended.

The authors identified several factors that might contribute to these diagnostic and treatment delays. One is the variation in clinicians’ knowledge of disease diagnosis and management. Another is the lack of point-of-care diagnostics. Panels typically used for the diagnosis of respiratory infections do not include the endemic mycoses. Serum antibody and urinary antigen tests for the endemic mycoses are typically available only from certain laboratories.

Plan of action to deal with endemic mycoses

The authors see an opportunity to improve fungal diagnostic and treatment practices through better surveillance and continuing medical education on these regional infections. They suggested a multifaceted approach to help with the preventive efforts and the timely recognition and treatment of these diseases. They called for:

1) national surveillance and disease reporting of endemic mycoses in both humans and animals

2) educational efforts for patients and providers

3) inclusion of endemic mycoses in future pneumonia guidelines

4) development of point-of-care diagnostic tools

5) exploration of a pan-endemic mycoses vaccine to prevent infection

CHICAGO—A team of Illinois Institute of Technology students has won the top prize in the Keysight Innovation Challenge 2022 for their novel “Tree of Life” technology—an Internet of Things device that will monitor soil and atmospheric conditions to help users decide which plants to grow to best sequester carbon and combat climate change.

The team of six Illinois Tech students presented their design to a panel of esteemed judges in Santa Rosa, California, on October 29, 2022, as part of the annual competition organized by Keysight Technologies Inc. The Illinois Tech team came in first out of 52 teams from around the globe and won $30,000 in cash, plus $10,000 worth of Keysight test equipment for Illinois Tech.

The team includes Chloe Rubinowicz (EE, M.S. EE 5th Year), Saurabh Saluja (CPE, M.S. CPE 5th Year), Colin Prochnow (CCSE, M.S. CPE 5th Year), Kaya Jones (CS 2nd Year), Anthony Banuelos (CCSE, M.A.S. CYF 5th Year), and Katarzyna Staron (ME, M.S. ME 5th Year).

“Our team learned and experienced more from this project than anything else we’ve done before,” says Chloe Rubinowicz (EE, M.S. EE 5th Year). “This has served as a pivotal moment for us, learning to work with a team to develop an idea and actualize it. Winning this competition has been surreal, and we’re so excited to see where our team goes from here.”

The team says Tree of Life was designed as a response to the urgent need for solutions to curb carbon emissions. 

“If we don’t act now, the consequences will be irreversible,” says Rubinowicz, lead of the Illinois Tech team. 

True to its name, the team’s groundbreaking device resembles a small tree. It’s “planted” in soil, where the in-ground sensor measures moisture level, electrical conductivity, temperature, nitrogen, phosphorus, potassium, and pH. Above ground, the device reads temperature, humidity, and carbon dioxide concentration, as well as GPS data and images from four cameras. Using that data and a database of more than 2,000 trees, an algorithm will determine what plants will grow best in the environment and remove the most CO2 from the atmosphere. The analyses and recommendations provided can also be scaled to large areas using additional inputs such as satellite imagery.  

“According to NASA, it would take 500 billion trees to offset the carbon emissions since 1990, which is a great undertaking. Luckily with our device, we can decrease the amount of trees by 30 percent,” says Saurabh Saluja (CPE, M.S. CPE 5th Year). “There’s no better time to start than now.”

The team has also built a website for the device that provides further analysis of the data collected including the estimated impact of planted trees, cost estimates, and recommendations of local nurseries where recommended trees can be purchased.

“At Illinois Tech, students are called  to be purpose-driven citizens. Our university was born to liberate the collective power of difference to drive innovation for all,” says Illinois Tech President Raj Echambadi. “The team’s fantastic work in producing this innovation to tackle one of the grand challenges of our time perfectly exemplifies the kind of drive to discovery we aim to develop in our students.”

The Keysight Innovation Challenge is a design competition challenging graduate and undergraduate engineering and computer science students to conceptualize an Internet of Things (IoT) device or network of devices that will provide carbon neutrality monitoring at the community or corporate level. The contest supported Keysight's goal to achieve carbon neutrality within its Corporate Social Responsibility policies. It aimed to inspire innovation to help the world reach net zero by 2050 and required each team to be woman-led to encourage gender diversity in STEM.

“It was fascinating to see the wide range of innovative solutions each student team created when posed the same challenge: to design an IoT device that will help the world reach net zero,” said Jeff Harris, vice president of portfolio and corporate marketing at Keysight, who also served as a judge and co-sponsor of the Keysight Innovation Challenge. “Each team looked at the question from a different angle and formed a unique solution. I’m excited for the future when we see this level of innovation and enthusiasm from our next generation of engineers.”

A panel of eight semifinal judges evaluated teams on metrics such as sensor effectiveness, AI capabilities, and cybersecurity resilience, with device prototypes evaluated by Keysight’s IoT Security Assessment software. The general public also played a role in judging by voting for their favorite design entries. These votes contributed to 10 percent of each entrant’s overall score.

Blood pressure highly likely to cause neurotic personality trait

Keeping it under control can help curb neuroticism, anxiety, and cardiovascular disease

Peer-Reviewed Publication

BMJ

Diastolic blood pressure—the lower of the two numbers in a blood pressure reading—is highly likely to cause neurotic personality trait, finds research published in the open access journal General Psychiatry.

And keeping it under control can help curb neurotic behaviours, anxiety, and heart and circulatory diseases, conclude the researchers.

High blood pressure is a major risk for cardiovascular disease and thought to be associated with psychological factors, such as anxiety, depression, and neuroticism—a personality trait characterised by susceptibility to negative emotions, including anxiety and depression. 

But which causes which isn’t entirely clear.

In a bid to find out, the researchers used a technique called Mendelian randomisation. This uses genetic variants as proxies for a particular risk factor—in this case, blood pressure—to obtain genetic evidence in support of a causal relationship, reducing the biases inherent in observational studies. 

Between 30% and 60% of blood pressure is down to genetic factors, and over 1000 genetic single nucleotide polymorphisms, or SNPs for short, are associated with it. SNPs help predict a person's response to certain drugs, susceptibility to environmental factors, and their risk of developing diseases.

The researchers drew on 8 large-scale study datasets containing whole genome DNA extracted from blood samples from people of predominantly European ancestry (genome-wide association studies).

They applied Mendelian randomisation to the 4 traits of blood pressure—systolic blood pressure (736,650 samples), diastolic blood pressure (736,650), pulse pressure (systolic minus diastolic blood pressure; 736,650), and high blood pressure (above 140/90 mm Hg; 463,010) with 4 psychological states—anxiety (463,010 samples), depressive symptoms (180,866), neuroticism (170,911) and subjective wellbeing (298,420).

The analysis revealed that high blood pressure and diastolic blood pressure had significant causal effects on neuroticism, but not on anxiety, depressive symptoms, or subjective wellbeing. 

But after adjusting for multiple tests, only diastolic blood pressure was significantly associated with neuroticism (over 90%), based on 1074 SNPs.  

The researchers acknowledge certain limitations to their findings. For example, it wasn’t possible to completely exclude pleiotropy–where one gene can affect several traits. And the findings may not be more widely applicable beyond people of European ancestry. 

But blood pressure links the brain and the heart, and so may promote the development of personality traits, they explain. 

“Individuals with neuroticism can be sensitive to the criticism of others, are often self-critical, and easily develop anxiety, anger, worry, hostility, self-consciousness, and depression. 

“Neuroticism is viewed as a key causative factor for anxiety and mood disorders. Individuals with neuroticism more frequently experience high mental stress, which can lead to elevated [blood pressure] and cardiovascular diseases,” they write.

And they suggest: “Appropriate surveillance and control of blood pressure can be beneficial for the reduction of neuroticism, neuroticism-inducing mood disorders, and cardiovascular diseases.”

Consumers feel left out of national debate on cyber attacks and data security

Australian public want more active role in detection and digital resilience

Peer-Reviewed Publication

FLINDERS UNIVERSITY

Illegal cyber attacks on thousands of citizens’ personal data in Australia has heightened awareness of the hazards of insecure digital systems – and Flinders University researchers say consumers want to play a more active role in building more resilient systems to reduce risks caused by hacking, online deception, bots and other threats.

Their study of a nationally representative sample of 1500 Australian citizens in 2020 – and focus groups comprising 62 people in three states – investigated attitudes to institutional trust, understanding of resilience, digital literacy and perceptions of cyber threats.

Even before the escalation in recent cyber breaches of Optus and Medibank Private customer bases, citizens in the surveys were clearly not confident or optimistic that Australia is keeping pace with cyber threats and interference in the country’s economy, politics or society.

“Not only are these citizens concerned about the technological capabilities of government – often citing poor experiences using online government services – but they also showed doubts about investment in skills and commitments to cybersecurity among businesses,” says Flinders University researcher Dr Josh Holloway.

“Quite reasonably, they tended to have little awareness of which public institutions and authorities are taking leadership in managing cyber threats and, collectively, expressed broad scepticism of social media and tech companies, media organisations, the federal government and public service generally.”

While survey participants wanted more capability and responsibility from the public sector and corporations, their trust in this process was low.

The findings, published in the journal Defence Studies, highlights the gap between Australian citizens’ knowledge and engagement and the broad response to cyber threats from top-down, technocratic and elite-driven agencies.

Co-author Associate Professor Robert Manwaring says Australian citizens’ confusion and lack of trust is not necessarily their fault.

“There’s generally little meaningful strategic effort to engage citizens in government-led responses, overlooking what’s often called the ‘social layer’ of cybersecurity,” says Associate Professor Manwaring. 

“We need to encourage a genuinely whole-of-society approach – something which like Sweden and Finland are making considerable inroads.”

The media also should play a greater role in informing the public and public debate around cyber threats.

“There’s clear scope for more nuanced, regular coverage of cyber risks – and one that is less focused on international ‘spectacle’ and reactive coverage.

“Australians need to be informed of the reality of cyber risk, and given the tools and information to participate in strategic efforts to enhance Australia’s cyber resilience, rather than just hearing about the fallout of successful cyber-attacks.”

The article, ‘Resilience to cyber-enabled foreign interference: citizen understanding and threat perceptions’ 2022 by Rob Manwaring and Josh Holloway has been published in Defence Studies DOI: 10.1080/14702436.2022.2138349.

DECRIMINALIZE DRINKING AT HOME

Tell UK government to raise legal at-home drinking age from 5 for kids, doctors urged

And dispel French drinking myth that early exposure staves off alcohol problems in later life

Peer-Reviewed Publication

BMJ

Children’s doctors in the UK need to take a much stronger and more visible steer in helping to ward off future alcohol problems by, among other things, campaigning to raise the legal at-home drinking age for kids from 5, argues an independent health education lecturer in a personal viewpoint, published online in the Archives of Disease in Childhood.

And they need to do far more to educate parents about the potential harms of early exposure to alcohol, including dispelling the French family drinking myth that childhood acculturation drives responsible drinking later on, argues Dr Aric Sigman. It doesn’t. 

Figures from the World Health Organization show that individual alcohol consumption in France and years of life lost are higher, while alcohol’s contribution to the overall death rate is 26% higher, than in the UK, he points out. 

Figures like these have prompted the French authorities to raise the legal drinking age and move to ‘denormalise’ drinking in a bid to curb the toll taken by alcohol on the nation’s health.

Alcohol is particularly problematic for the young, highlights the author. Globally, it remains the leading risk factor for premature death and disability among 15–49 year olds, and is a causal factor in more than 200 disease and injury conditions, including “staggering increases in liver disease mortality over the last 40 years, especially in the UK,” he points out.

Delaying the age at which children and young people take their first drink, even small sips, may lower their subsequent risk of becoming problem drinkers, he says.

Preliminary research suggests that introducing children to alcohol may sensitise the neurocircuitry of addiction by inducing neuroadaptations in brain regions involved in reward and addiction. Teen drinking may also lead to changes in gene expression that could influence drinking behaviour in adulthood, he adds.

“A more visible position by the paediatric profession is required which wrests ownership from that of alcohol initiation being a cultural issue to being a formal medical issue presided over by paediatric medicine—not the national culture,” he insists.

Doctors can educate parents about role modelling. Rather like tobacco, children who see their parents drink are more likely to try it themselves, and that includes using alcohol to ‘self medicate,’ he says.

And doctors can highlight the ‘normalising’ influence of the alcohol industry on school teaching materials, including lesson plans, fact sheets, and films, through their charities, youth education projects, and education trusts, he suggests.

And they can lobby the government to raise the at-home drinking age from 5—not as an attempt “to criminalise parents, but as a signal to reset the alcohol cultural landscape through formal gesture”accompanied by the inclusion of mandatory warnings on all alcohol products and health promotion materials, stating that delaying the drinking age may reduce children’s lifetime risk of alcohol use disorders, he suggests.

“It is time we join the dots and take a far broader and more long-term approach to prevent and reduce future alcohol-related morbidity and mortality,” he writes.

“The paediatric profession has the respect and the authority to tell society not what it is interested in hearing, but what is in its children’s best interests,” he concludes.

Put the kettle on! How black tea (and other favorites) may help your health later in life


Thanks to flavonoids, a daily cup could help you to enjoy better cardiovascular health late in life — however if you’re not a tea drinker, there are other things you can add to your diet

Peer-Reviewed Publication

EDITH COWAN UNIVERSITY

A daily cup of tea could help you to enjoy better health late in life — however if you’re not a tea drinker, there are other things you can add to your diet.

The key is flavonoids, which are naturally occurring substances found in many common foods and beverages such as black and green tea, apples, nuts, citrus fruit, berries and more.

They have long been known to have many health benefits — however new Edith Cowan University (ECU) research shows they may be even better for us than previously thought.

The Heart Foundation supported a study of 881 elderly women (median age of 80), which found they were far less likely to have extensive build-up of abdominal aortic calcification (AAC) if they consumed a high level of flavonoids in their diet.

AAC is the calcification of the abdominal aorta — the largest artery in the body which supplies oxygenated blood from the heart to the abdominal organs and lower limbs — and is a predictor of cardiovascular risk such as heart attack and stroke.

It has also been found to be a reliable predictor for late-life dementia.

ECU Nutrition and Health Innovation Research Institute researcher and study lead Ben Parmenter said while there were many dietary sources of flavonoids, some had particularly high amounts.

“In most populations, a small group of foods and beverages—uniquely high in flavonoids—contribute the bulk of total dietary flavonoid intake,” he said.

“The main contributors are usually black or green tea, blueberries, strawberries, oranges, red wine, apples, raisins/grapes and dark chocolate.” 

The flavonoid family

There are many different types of flavonoids, such as flavan-3-ols and flavonols, which the study indicated appear to also have a relationship with AAC.

Study participants who had a higher intake of total flavonoids, flavan-3-ols and flavonols were 36-39 per cent less likely to have extensive AAC.

Black tea was the study cohort’s main source of total flavonoids and was also associated with significantly lower odds of extensive AAC.

Compared with respondents who didn’t drink tea, participants who had two-to-six cups per day had 16-42 per cent less chance of having extensive AAC.

However, some other dietary sources of flavonoids such as fruit juice, red wine and chocolate, did not show a significant beneficial association with AAC.

Not just tea

Though black tea was the main source of flavonoids in the study — likely due to the age of the participants — Mr Parmenter said people could still benefit from flavonoids without putting the kettle on.

“Out of the women who don’t drink black tea, higher total non-tea flavonoid intake also appears to protect against extensive calcification of the arteries,” he said.

“This implies flavonoids from sources other than black tea may be protective against AAC when tea is not consumed.”

Mr Parmenter said this was important as it allows non-tea drinkers to still benefit from flavonoids in their diet.

“In other populations or groups of people, such as young men or people from other countries, black tea might not be the main source of flavonoids,” he said.

“AAC is a major predictor of vascular disease events, and this study shows intake of flavonoids, that could protect against AAC, are easily achievable in most people’s diets.”

‘Higher habitual dietary flavonoid intake associates with less extensive abdominal aortic calcification in a cohort of older women’ was published in Arteriosclerosis, Thrombosis, and Vascular Biology.
