I did it! I took a chance, followed my gut, and launched something brand new. I told myself what I always tell you guys…Risk It! or Regret It! Introducing my brand-new short-form syndicated radio feature: “Keeping the ‘Live' in Alive! with Debbie Nigro” Proudly sponsored by NativePath Collagen — the stuff that's got me hiking again, baby! For the past 6 months, I've been secretly developing this new ‘thing''. Figuring out what it should be, how it should sound, and who would be open enough to collaborate with me.   Why this, why now? Lately, I've found myself diving into wellness like never before. Not just for fun (though some of it is hilarious), but because my biological clock feels more like a ticking time bomb these days. I'm trying to maximize my remaining time on this planet as are many other people I know. I'm constantly researching and talking about mental wellness, physical wellness, nutrition, longevity, and all the weird and wonderful science behind staying vibrant and ALIVE. And sharing it all on my “Wellness Wednesday” segments of The Debbie Nigro Show just wasn't enough anymore. So, I created this new feature — fast-moving, funny, and full of fascinating wellness info — to syndicate nationwide. AND I'm testing it out in real time.    The Launch

Biophilia was coined from a theory of the biologist, E. O. Wilson, who stated that human beings have an innate and even genetically determined affinity to nature. In other words, it is important that this connection is kept to facilitate wellness. In this episode, Dr. Vanessa Champion, editor and founder of The Journal of Biophilic Design, joins Lori to review initiatives which can be taken in senior living environments in response to this very human need... and why these interventions are necessary.

Une étude récente publiée dans Nature Aging par des chercheurs de l'Université de Washington a mis en lumière le rôle crucial des cellules immunitaires du cerveau, appelées microglies, dans le développement de la maladie d'Alzheimer. Traditionnellement considérées comme les gardiennes du système nerveux central, les microglies jouent un rôle essentiel dans la surveillance et la protection du cerveau. Cependant, cette étude révèle que, dans certaines conditions, ces cellules peuvent contribuer à la progression de la neurodégénérescence.Les microglies sont des cellules immunitaires résidant dans le cerveau, capables de détecter et de répondre rapidement aux anomalies, telles que les dépôts de protéines bêta-amyloïdes caractéristiques de la maladie d'Alzheimer. En temps normal, elles phagocytent ces dépôts pour protéger les neurones. Toutefois, l'étude de l'Université de Washington a découvert qu'une sous-population de microglies, lorsqu'elle est suractivée par le stress lié au processus dégénératif, libère des lipides toxiques qui aggravent la neurodégénérescence. Cette suractivation entraîne une réponse inflammatoire excessive, contribuant à la progression de la maladie.Les chercheurs ont observé ce phénomène chez des modèles murins atteints de la maladie d'Alzheimer. Ils ont également identifié la présence de ces microglies suractivées dans le tissu cérébral de personnes décédées avec la maladie. Ces découvertes suggèrent que, bien que les microglies aient un rôle protecteur initial, leur suractivation peut devenir délétère, exacerbant les dommages neuronaux.Cette étude souligne l'importance de réguler l'activité microgliale pour prévenir ou ralentir la progression de la maladie d'Alzheimer. Des approches thérapeutiques visant à moduler la réponse des microglies pourraient offrir de nouvelles perspectives dans le traitement de cette pathologie neurodégénérative. Par exemple, des stratégies visant à réduire la libération de lipides toxiques par les microglies suractivées ou à inhiber leur suractivation pourraient être explorées.En conclusion, les microglies jouent un rôle double dans la maladie d'Alzheimer : protectrices en phase initiale, elles peuvent devenir nuisibles lorsqu'elles sont suractivées. Comprendre les mécanismes qui régulent cette transition est essentiel pour développer des interventions thérapeutiques efficaces. Les travaux de l'Université de Washington apportent une contribution significative à cette compréhension, ouvrant la voie à de nouvelles recherches sur le rôle des cellules immunitaires du cerveau dans les maladies neurodégénératives.

What the dinosaurs left behind tells the story of their rise to dominanceBones aren't the only thing we can use to understand the dinosaurs. A new study of a rich trove of fossilized feces and vomit is telling the story of how dinosaurs diversified and came to dominate the planet starting 230 million years ago. Paleontologist Martin Qvarnström from Uppsala University in Sweden said it appears that the secret to dinosaurs' success is in their ability to adapt to their changing environment. Their research is published in the journal Nature. A new kind of ‘walking' shorts could help with mobilityScientists have incorporated artificial tendons and electric motors into shorts to provide support and assistance to the hip flexor muscles that are critical for walking. In both young and old people the shorts improved performance and so could make a difference for those whose mobility has been compromised. Enrica Tricomi, a visiting researcher at the Technical University of Munich, co-developed this prototype. The study was published in the journal Nature.Shining a bright light on a new way to discourage shark attacksSharks attacks on humans are often a result of mistaken identity, when they mistake a swimming human or a surfboard for a seal or sea lion.

But according to a new study by S. Jay Olshansky, those gains have started to flatline in recent years. By looking at the countries with the longest lifespans, Olshansky and his colleagues found that we have traded childhood diseases for age-related diseases like cancers and Alzheimer's, and so we shouldn't expect to make many more gains in human lifespan using our current methods. Instead, he says, we should focus on improving the quality of the extra years we've gained so far. His work was published in the journal Nature Aging.We also speak with William Mair, a Professor of Molecular Metabolism at the Harvard School of Public Health. He is part of a new field of study called Geroscience, which looks at slowing down the process of aging as a whole. In his lab he has been able to extend the lifespan of simpler creatures like nematode worms and mice, and says while we have no proof we can extend a human's maximum lifespan at this time, that doesn't mean it won't be possible in the future.

Don’t expect human life expectancy to grow much more, researcher says

Humanity is hitting the upper limit of life expectancy, according to a new study. Advances in medical technology and genetic research—not to mention larger numbers of people making it to age 100—are not translating into marked jumps in lifespan overall, according to researchers who found shrinking longevity increases in countries with the longest-living populations. “We have to recognize there's a limit” and perhaps reassess assumptions about when people should retire and how much money they'll need to live out their lives, said S. Jay Olshansky, a University of Illinois-Chicago researcher who was lead author of the study published by the journal Nature Aging. “We are reaching a plateau” in life expectancy, he agreed. It's always possible some breakthrough could push survival to greater heights, “but we don't have that now,” said Mark Hayward, a University of Texas researcher. Life expectancy is one of the world's most important health measures, but it is also imperfect: It is a snapshot estimate that cannot account for deadly pandemics, miracle cures, or other unforeseen developments that might kill or save millions of people. In the new research, Olshansky and his research partners tracked life expectancy estimates for the years 1990 to 2019, drawn from a database administered by the Max Planck Institute for Demographic Research. The researchers focused on eight of the places in the world where people live the longest—Australia, France, Hong Kong, Italy, Japan, South Korea, Spain, and Switzerland. The study suggests that there's a limit to how long most people live, and we've about hit it, Olshansky said. “We're squeezing less and less life out of these life-extending technologies. And the reason is, aging gets in the way,” he said. It may seem common to hear of a person living to 100. In 2019, a little over 2% of Americans made it to 100, compared with about 5% in Japan and 9% in Hong Kong, Olshansky said. It's likely that the ranks of centenarians will grow in the decades ahead, experts say, but that's because of population growth. The percentage of people hitting 100 will remain limited, likely with fewer than 15% of women and 5% of men making it that long in most countries, Olshansky said.

A new study says humanity is hitting the upper limit of life expectancy. 一项新的研究表明,人类正在达到预期寿命的上限。 Developments in medical technology and genetic research are not leading to major increases in lifespan overall, the researchers said. 研究人员表示,医疗技术和基因研究的发展并没有导致整体寿命的大幅延长。 The study was published recently in Nature Aging. 该研究最近发表在《自然衰老》杂志上。 “We have to recognize there's a limit” and possibly change ideas about when people should retire and how much money they will need to live out their lives, said S. Jay Olshansky of the University of Illinois-Chicago. Olshansky was the lead writer of the study. 伊利诺伊大学芝加哥分校的 S. Jay Olshansky 表示,“我们必须认识到这是有限制的”,并可能改变人们关于何时退休以及需要多少钱来度过余生的想法。奥尔尚斯基是这项研究的主要作者。 Mark Hayward of the University of Texas was not involved in the study. However, he called it “a valuable addition to the mortality literature.” 德克萨斯大学的马克·海沃德没有参与这项研究。然而,他称其为“对死亡率文献的宝贵补充”。 “We are reaching a plateau” in life expectancy, he said. 他说,预期寿命“我们正在达到一个平台期”。 It is always possible that some new development could push survival to greater lengths, “but we don't have that now,” Hayward said. 海沃德说,一些新的发展总是有可能将生存推向更大的长度,“但我们现在还没有这样的能力”。Life expectancy is an estimate of the average number of years a baby born in a particular year might expect to live. The measurement assumes death rates at the time of birth do not change. 预期寿命是对特定年份出生的婴儿预期寿命的平均年数的估计。该测量假设出生时的死亡率没有变化。 Life expectancy is one of the world's most important health measures. Still the life expectancy measurement has problems. For example, life expectancy is an estimate that cannot include new developments or changes that might affect the length of people's lives. 预期寿命是世界上最重要的健康指标之一。预期寿命的测量仍然存在问题。例如,预期寿命是一种估计值,不能包括可能影响人们寿命长度的新发展或变化。 These unknown developments could include pandemics or new treatments for diseases. 这些未知的发展可能包括流行病或疾病的新疗法。 In the recent study, Olshansky and other researchers followed life expectancy estimates for the years 1990 to 2019. They took information from a database administered by the Max Planck Institute for Demographic Research. 在最近的研究中,奥尔尚斯基和其他研究人员跟踪了 1990 年至 2019 年的预期寿命估计。他们从马克斯·普朗克人口研究所管理的数据库中获取信息。 The researchers paid special attention to eight of the places in the world where people live the longest: Australia, France, Hong Kong, Italy, Japan, South Korea, Spain and Switzerland.研究人员特别关注了世界上人们寿命最长的八个地方:澳大利亚、法国、香港、意大利、日本、韩国、西班牙和瑞士。 The United States does not rank in the top 40, but it was included in the study because the researchers live in the U.S. Also, some experts have made estimates that life expectancy in the U.S. would increase greatly in the 2000s, Olshansky said. 奥尔尚斯基表示,美国并未进入前40名,但由于研究人员居住在美国,因此被纳入研究范围。此外,一些专家估计,美国的预期寿命将在2000年代大幅增加。Women continue to live longer than men. Female life expectancy improvements are still happening — but at a slower rate, the researchers found. In 1990, the average amount of improvement was about 2.5 years every 10 years. In the 2010s, it was 1.5 years — but almost zero in the United States. 女性的寿命仍然比男性长。研究人员发现,女性预期寿命仍在延长,但速度较慢。1990年,平均每10年改善2.5年左右。2010 年代,这个数字是 1.5 年——但在美国几乎为零。 Life expectancy measurements in the U.S. are more difficult. The country is affected by a number of causes of early death. Examples include drug overdoses, shootings, weight problems and uneven health care services. 美国的预期寿命测量更加困难。该国受到多种早逝原因的影响。例子包括药物过量、枪击、体重问题和医疗保健服务不均衡。But in one calculation, the researchers estimated what would happen in all nine places if all deaths before age 50 were prevented. The increase at best was still only 1.5 years, Olshansky said. 但在一项计算中,研究人员估计了如果 50 岁之前的所有死亡都被避免的话,所有九个地方将会发生什么。奥尔尚斯基说,最好的情况是增加了 1.5 年。 The study suggests that there is a limit to how long most people live, and we have almost hit it, Olshansky said. 奥尔尚斯基说,这项研究表明,大多数人的寿命是有极限的,而我们几乎已经达到了极限。 “We're squeezing less and less life out of these life-extending technologies. And the reason is, aging gets in the way,” he said. “我们从这些延长生命的技术中榨取的生命越来越少。原因是,衰老会成为障碍,”他说。 It may seem common to hear of a person living to 100. Former U.S. President Jimmy Carter, for example, recently celebrated his 100th birthday. 听说有人活到 100 岁似乎很常见。例如,美国前总统吉米·卡特 (Jimmy Carter) 最近庆祝了他的 100 岁生日。 In 2019, a little over two percent of Americans made it to 100, compared to about five percent in Japan and nine percent in Hong Kong, Olshansky said. 奥尔尚斯基说,2019 年,略高于 2% 的美国人达到了 100 岁,而日本和香港的这一比例约为 5% 和 9%。 It is likely that the number of people who reach 100 will grow in the years ahead, experts say, but that is because of population growth. The percentage of people hitting 100 will remain limited, likely with fewer than 15 percent of women and 5 percent of men making it that long in most countries, Olshansky said. 专家表示,未来几年,活到 100 岁的人数可能会增加,但这是因为人口增长。奥尔尚斯基表示,活到 100 岁的人口比例仍然有限,在大多数国家,能活到 100 岁的女性和男性可能只有不到 15% 和 5%。

Subscribe to our channel: https://www.youtube.com/@optispan How much longer might humans live? This question has fascinated scientists, philosophers, and dreamers for centuries. The average human lifespan has already increased dramatically over the past hundred years thanks to advances in medicine, public health, and technology, and the prospect of radically extending human life remains one of humanity's most compelling frontiers. A recent paper published in the scientific journal Nature Aging argues that radical life extension is unlikely to happen in the 21st century. The paper has sparked fascinating conversation in the longevity industry around topics such as realistic deliverables for the field, the predictive value of past technological trajectories, the reasons behind lifespan decreases in the western world, incremental versus bold research goals, and where we should go from here. Matt and Nick discuss the paper and provide their own take on the prospect of radical life extension and what we can realistically expect to see in the coming decades.

Feeling like you've aged 10 years in just a few months? New research published in Nature Aging might offer some insight. The study involved 108 volunteers aged between 25 and 75, who provided blood, stool, skin, oral, and nasal samples every few months over a period of up to seven years. Researchers measured levels of 135,000 different molecules, including RNA, proteins, and metabolites, as well as bacteria, fungi, and viruses present on the skin and in the gut. Rather than observing a gradual aging process, the researchers identified two distinct spikes where aging accelerates - one around age 44 and another at age 60. The first spike, at age 44, was linked to changes in molecules associated with cardiovascular disease, as well as a reduced ability to metabolise caffeine, alcohol, and fats. Interestingly, these shifts occurred in both men and women, debunking the notion that they were solely related to perimenopause in women. The second spike, at age 60, was connected to changes in molecules linked to immune function, kidney function, and carbohydrate metabolism. Both age-related spikes also showed significant changes in molecules related to skin and muscle aging. These findings align with the noticeable increase in certain diseases at specific ages, such as cardiovascular disease starting around age 40, and Parkinson's and Alzheimer's diseases becoming more common after age 60. While the study didn't offer strategies to slow down these rapid aging changes, the researchers did suggest that these ages might be key milestones to monitor our health closely. Booking a full medical check-up around these times could be a smart move for preventive care. LISTEN ABOVESee omnystudio.com/listener for privacy information.

The public discussion in a number of countries around the world expresses worries about what is called an aging society. These countries anticipate a future with fewer younger people who are active members of the economy, and a growing number of older people who need to be supported by the people still in the workforce. It's an inversion of the usual demographic pyramid, with less at the bottom, and more at the top.However, our guest in this episode recommends a different framing of the future – not as an aging society, but as a longevity society, or even an evergreen society. He is Andrew Scott, Professor of Economics at the London Business School. His other roles include being a Research Fellow at the Centre for Economic Policy Research, and a consulting scholar at Stanford University's Center on Longevity.Andrew's latest book is entitled “The Longevity Imperative: Building a Better Society for Healthier, Longer Lives”.

Today we're diving into some groundbreaking research that could potentially change the game when it comes to aging. Our spotlight is on a recent study published in Nature Aging by Cold Spring Harbor Laboratory, and it's all about using a "living" drug called chimeric antigen receptor(CAR) T Cells to tackle those pesky senescent cells. But before we get into the nitty-gritty, let's break it down for you in simple terms. Imagine your body as a city and senescent cells are like those old, rundown buildings that just refuse to budge. They don't function properly, and worse, they release signals that can negatively affect the surrounding healthy cells. These cells are dysfunctional and shoot out signals that wreak havoc on their healthy neighbors. Now, the researchers at CSHL is proposing a superhero-like solution: CAR T Cells.

They explore how graph neural networks were trained on screening data to evaluate large chemical spaces and identify new senolytic molecules with medicinal properties superior to those of previously known compounds.Key topics:What cellular senescence is and why selectively eliminating senescent cells may have therapeutic benefits for aging and age-related diseasesLimitations of traditional high-throughput screening approaches and the vastness of chemical spaceHow graph neural networks work and how Felix's team trained them on senolytic screening dataApplying the models to search much larger chemical libraries and identify promising new senolytic scaffoldsExperimental validation and characterization of hits from the AI screeningThe potential to use this machine learning approach more broadly for phenotypic drug discoveryFelix's new company Integrated Biosciences and their mission to control cellular stress responses using synthetic biology and AIQuotes:Quotes have been lightly edited for clarity."We found that machine learning models might allow us to more productively search chemical space and increase our working hit rates.""What was fascinating to us about senescence cells is that, unlike other pathologies or diseases, these cells are not really characterized by a single target.""The quality of any machine learning model is limited by the quality of the training data. And that in turn is limited by how good your screens are, and how good your understanding of the biology is."“That's really what machine learning is doing, trying to think about things in a very high dimensional manner. And then trying to build models that help to separate what is positive and what is negative.”“So what ideally we would want is for any model to be able to generalize, to be able to predict chemical scaffolds that the model has not previously seen, and positively identify those scaffolds as new senolytics.”"Ideally, we would like to treat aging and age-related diseases, just like how antibiotics treat bacterial infections."“At Integrated, we're trying to kind of look at these stress responses holistically.

Eating fewer calories appears to slow the pace of aging and increase longevity in healthy adults, according to a study published in the journal Nature Aging. The study, which was funded by the National Institute on Aging, part of the National Institutes of Health, is the first-ever randomized controlled trial that looked at the long-term impact of calorie restriction. It adds to an already large body of evidence that a calorie-restricted diet can provide substantial health benefits, including delayed aging, said the study's senior author, Dan Belsky, who is assistant professor of epidemiology at Columbia University's Mailman School of Public Health in New York City. Wellness Expert, Speaker & Author Dr. Mary Warren joins JT to discuss this new study.

Last Thursday, scientists at Columbia University published a new study finding that cutting down on calories could lead to longer lives. In the phase 2 trial, 220 healthy people without obesity dropped their calories significantly, and a test of their biological age showed that their rate of aging slowed by 2 to 3 percent in over a couple of years. Small though that may seem, it amounts to a decline of about 10 percent in the risk of death as people get older, according to the researchers' estimate. That's basically the same as quitting smoking.Previous research has shown that restricting calories results in longer lives for mice, worms and flies. This research is unique because it applies those findings to people. It was published in Nature Aging.But what did the researchers actually show? Does the new paper point to anything people should be doing to have longer, healthier lives? Spoiler alert: Maybe, but first, you'd want to consult a medical expert about it. I had the chance to chat with someone with inside knowledge of the research -- Dr. Evan Hadley, director of the National Institute of Aging's Division of Geriatrics and Clinical Gerontology, which funded the study. Dr. Hadley describes how the research participants went about reducing their calories, as well as the risks and benefits involved. He also explains the "aging clocks" used to measure the benefits.Leaps.org is a not-for-profit initiative that publishes award-winning journalism, popularizes scientific progress on social media, and hosts events about bioethics and the future of humanity.

Please join author Subodh Verma and Guest Editor Christopher Granger as they discuss the article "Empagliflozin and Left Ventricular Remodeling in People Without Diabetes: Primary Results of the EMPA-HEART 2 CardioLink-7 Randomized Clinical Trial." Dr. Carolyn Lam: Welcome to Circulation on the Run, your weekly podcast summary and backstage pass to the journal and its editors. We're your co-host. I'm Dr. Carolyn Lam, associate editor from the National Heart Center and Duke National University of Singapore. Dr. Peder Myhre: And I'm Dr. Peder Myhre, social media editor and doctor at Akershus University Hospital at University of Oslo in Norway. Dr. Carolyn Lam: Peder, I am so excited to be discussing this issue. So many great articles and a feature discussion coming up on the SGLT2 inhibitor, empagliflozin. And do you think it's got effects on left ventricular remodeling in people without diabetes? Very interesting question. Dr. Peder Myhre: That is so interesting, Carolyn. I can't wait to hear this discussion. Dr. Carolyn Lam: Yep, I agree, but we got to wait till we discuss the other papers in today's issue. I want to go first. So we know that non-vitamin K oral anticoagulants, or NOACs, they've become the standard therapy for preventing stroke and ischemic thromboembolism in most patients with atrial fibrillation. But, what is the effectiveness and safety of NOACs in patients on dialysis? That is hemodialysis. The AXADIA-AFNET 8 study sought to test the hypothesis that apixaban would be non-inferior to vitamin K antagonists in these very patients undergoing hemodialysis. Dr. Peder Myhre: Oh wow. This is really a gap of knowledge that we've been waiting to hear more about. NOACs in patients with hemodialysis. Tell us about this trial, Carolyn. Dr. Carolyn Lam: Sure. So this is from corresponding author, Dr. Reinecke, and colleagues, from University of Munster in Germany. And it's an investigator initiated prospective randomized open-blinded outcome assessment of 97 patients with atrial fibrillation on chronic hemodialysis randomized to either apixaban 2.5 mg BID, or a vitamin K antagonist, aiming for an INR between 2 and 3. Over a median follow-up time of 429 days for apixaban, and 506 days for the vitamin K antagonist, the composite primary safety outcome of first, major bleeding, clinically relevant, non-major bleeding, or all cause death, occurred in 46% of patients on apixaban, and 51% of patients on the vitamin K antagonist. That would be a hazard ratio of 0.91, with a p for non-inferiority being 0.157. How about the primary efficacy outcome? While this was a composite of ischemic stroke, all cause death, myocardial infarction, or deep vein thrombosis, and/or pulmonary embolism, and that occurred in 21% of patients on apixaban and 31% of patients on the vitamin K antagonists. Again, no difference when there was testing. So, in summary, Peder, there were no differences in the safety or efficacy observed between apixaban and vitamin K antagonists in patients with atrial fibrillation on chronic hemodialysis. Of note, however, even receiving oral anticoagulations, these patients remain at very high risk of cardiovascular events. So these data really support the consideration of apixaban for prevention of cardiovascular complications in patients with atrial fibrillation on chronic hemodialysis, but larger studies are definitely needed. Dr. Peder Myhre: Oh wow, Carolyn, that is so clinically relevant. And the next paper is also a clinically relevant paper. And it comes to us from the SPRINT authors. And to remind you, the SPRINT study was a study of intensive systolic blood pressure lowering compared to standard blood pressure lowering. And the results demonstrated that there was a robust reduction in both heart failure endpoints and all cause mortality. And in this sub-study that comes to us from corresponding author Jarett Berry from University of Texas Tyler School of Medicine, these authors look at the mechanisms through which intensive blood pressure lowering reduces the risk of these endpoints. And given the important role of cardiac injury and neurohormonal activation in the pathways leading from hypertension to heart failure, and strong association that has been observed between hypertension and levels of cardiac troponin and NT-proBNP, the authors hypothesized that intensive systolic blood pressure lowering would decrease levels of high sensitivity cardiac troponin T and NT-proBNP. Dr. Carolyn Lam: Cool. That's interesting. So how did they do this, and what did they find? Dr. Peder Myhre: So, as expected, Carolyn, the authors found that increases in troponin and NT-proBNP from baseline to 1 year were associated with a higher risk of heart failure and death. And there were really no significant interaction by treatment assignment. But let's look at the changes in troponin. And these results showed that randomization to intensive blood pressure lowering versus standard blood pressure lowering resulted in a significant 3% increase in cardiac troponin T level over 1 year follow up, and a higher proportion of participants with more than 50% increase, and that's with an odds ratio of 1.47. And Carolyn, in contrast, NT-proBNP decreased by 10% in intensive blood pressure arm. And these patients had substantially lower probability of increasing more than 50% in NT-proBNP, with an odds ratio of 0.57 compared to the standard arm. And now, to the most interesting part of this analysis, Carolyn, the association of randomized treatment assignment on changes in troponin was completely attenuated after accounting for changes in eGFR during the follow up, whereas the association of treatment with NT-proBNP changes were completely attenuated after adjusting for changes in systolic blood pressure. So Carolyn, the authors highlight in their discussion the importance of non-cardiac factors influencing variation in cardiac biomarkers, and raise questions about the potential role of cardiac troponin T as a surrogate marker for heart failure or death in blood pressure lowering studies. Dr. Carolyn Lam: Wow, very interesting. Thanks, Peder. Can I tell you now about a preclinical study? Very interesting, because it shows that cardiac inflammation and hypertrophy are regulated by a heart-brain interaction. Dr. Peder Myhre: Wow, Carolyn, a heart-brain interaction. I'm excited to hear more about this. Please explain. Dr. Carolyn Lam: I'd love to, but first some background. Interleukin-1 beta, now that is a pro-inflammatory cytokine that causes cardiac hypertrophy and heart failure. I need to familiarize you with this, the nucleotide-binding domain leucine-rich containing family, pyrin domain-containing-3, NLRP3 for short, which is an inflammasome, which is a cytosolic multiprotein complex that mediates active interleukin-1 beta production. Okay? So you know these terms, and now I want to tell you about the study. This is an elegant series of experiments performed by co-corresponding authors, Dr. Higashikuni, from University of Tokyo, and Dr. Sata, from Tokushima University Graduate School of Medicine, and their colleagues. They first showed that genetic disruption of the NLRP3 inflammasome resulted in significant loss of interleukin-1 beta production, cardiac hypertrophy, and contractile function during pressure overload. Next, a bone marrow transplantation experiment revealed an essential role of NLRP3 inflammasome in cardiac non-immune cells in myocardial interleukin-1 beta production and the cardiac phenotype. It was extracellular ATP released from sympathetic nerve terminals that induced the hypertrophic changes of cardiac cells in an NLRP3 and interleukin-1 beta dependent manner in vitro. And finally, depletion of ATP release from sympathetic efferent nerves, or ablation of cardiac afferent nerves, or a lipophilic beta-blocker, all reduced cardiac extracellular ATP, and inhibited the NLRP3 inflammasome activation, the interleukin-1 beta production, and the adaptive cardiac hypertrophy during pressure overload. So all of this suggests that controlling the neuronal brain signals might have therapeutic potential for the treatment of hypertensive heart disease. Neat, huh? Dr. Peder Myhre: Oh, that is so interesting. The heart and brain interaction. And, Carolyn, we're going to stay in the field of preclinical science. And now we're going to talk about another field that is really interesting, and that is regeneration of cardiomyocytes. Because, Carolyn, developmental cardiac tissue holds remarkable capacity to regenerate after injury, and consists of regenerative mononuclear and deployed cardiomyocytes. Whether reprogramming metabolism promotes persistence of these regenerative mononuclear and deployed cardiomyocytes that enhance cardiac function in repair after injury is unknown. Therefore, these researcher, led by corresponding author, Mohsin Khan, from Temple University School of Medicine, investigated whether the RNA binding protein, LIN28a, which is a master regulator of cellular metabolism, plays a role in cardiac repair following injury. Dr. Carolyn Lam: Wow. That is always, always interesting, regeneration and repair following injury. So what did the authors find? Dr. Peder Myhre: Well, Carolyn, through a number of elegant experiments, the authors made the following key findings. For the first time, they documented a role for RNA binding protein LIN28A in regulating cardiomyocyte turnover in the postnatal and adult heart. And LIN28a overexpression promotes cardiomyocyte cell cycle activity during postnatal development and extends cardiac regenerative ability of the mammalian heart to postnatal day 7. And in the adult heart, the authors could demonstrate that LIN28a drives new myocyte formation, augmenting cardiac structure and function after myocardial injury. And Carolyn, I'm sure you're going to ask the clinical implications of this study. Dr. Carolyn Lam: Indeed. Dr. Peder Myhre: And that is that these results may suggest a novel translational role for LIN28a based strategy to replenish cardiomyocytes in the adult heart after injury. Dr. Carolyn Lam: Very nice, Peder. Thank you. Also in the issue is a Research Letter by Dr. Bick on interleukin-6 receptor polymorphism attenuates clonal hematopoiesis mediated coronary artery disease risk among many individuals in the UK Biobank. There's also Cardiology News by Tracy Hampton, where she highlights few really interesting things, like aging cardiomyocytes accumulate new genetic mutations that was published in Nature Aging, cytokines promote tissue repair after a heart attack in mice, and that was published in Science, and scientists identifying molecular alterations in a failing heart at a single cell resolution, which was published in Nature. Dr. Peder Myhre: And there are a couple of other papers also in this issue, Carolyn. And there's first, an exchange of letters by Drs. Halushka, Lu, and Mayr, regarding the article "Circulating MicroRNA-122-5p is Associated with a Lack of Improvement in Left Ventricular Function after TAVR and Regulates Viability of Cardiomyocytes Through Extracellular Vesicles." And finally, we have an "On My Mind" piece by doctors Monda and Limongelli entitled "An Integrated Sudden Cardiac Risk Prediction Model for Patients with Hypertrophic Cardiomyopathy." Dr. Carolyn Lam: Oh, nice. Nice full issue. Thank you, Peder. Let's go to our feature discussion now. Shall we? Dr. Peder Myhre: Let's go. Dr. Greg Hundley: Welcome listeners to this feature discussion on January 24th. And we have with us Dr. Subodh Verma, from St. Michael's University in Toronto, Canada. And a guest editor, Dr. Christopher Granger, from Duke University in Durham, North Carolina. Welcome gentlemen. Well, Subodh, we will start with you. Can you describe for us some of the background information that went into the preparation of your study, and what was the hypothesis that you wanted to address? Dr. Subodh Verma: First, my great pleasure to be here, and thank you very much for the opportunity to discuss this paper with your viewers. As you know, SGLT2 inhibitors have been truly transformative therapies. From a heart failure perspective, we know that they prevent incident heart failure in people with diabetes who have vascular disease or risk factors. They also have been shown to treat prevalent heart failure in people with heart failure and either a reduced, mildly reduced, or preserved ejection fraction independent of glycemic status. And really, these have been the basis of very strong recommendations to use these agents in the prevention of heart failure in people with diabetes, and also in the treatment of prevalent heart failure in people with and without diabetes. Now, the fact that these drugs have such broad effects in people with heart failure has led to a theory that maybe these drugs could be introduced earlier on in the natural history of heart failure in people who neither have diabetes nor have significant heart failure, the so-called sort of stage A or stage B patient. But there really have been no clinical trials evaluating this question. There've been a lot of translational randomized trials that have provided some mechanistic insights about LV remodeling in people with diabetes or in people with prevalent heart failure. And we hypothesized that maybe the first step to evaluate whether SGLT2 inhibitors may have favorable effects on cardiac remodeling in people without diabetes or without heart failure would be to conduct a randomized double-blind control trial looking at indices of left ventricular remodeling in a population that I've just described. Dr. Greg Hundley: Very nice, Subodh. So you've started us into your study design. Maybe describe that a little more fully, and then who was included in your study population? Dr. Subodh Verma: So EMPA-HEART 2 CardioLink was a multi-center double-blind placebo control randomized trial in which we studied the effects of empagliflozin, an SGLT2 inhibitor, at a dose of 10 mg per day versus placebo in people who did not have type 2 diabetes or significant heart failure. We included people who were adults between the age of 40 and 80 who met 1 of 2 entry criteria. Either they had to have one major criteria, which was an increase in left ventricular mass index by specific echo criteria or MRI criteria, or they could have increased LVH as identified by ECG or by intraventricular septal or posterior wall thickness. They could also get in if they had resistant hypertension, hypertension despite being on 3 antihypertensive agents, or the second strata was entry through 2 minor criteria, which included a history of myocardial infarction, a GFR between 30 or 60, or evidence of overweight or obesity. Dr. Greg Hundley: And how many subjects did you randomize? Dr. Subodh Verma: So we randomized, of the 318 that we screened, 169 were randomized to receive empagliflozin 10 mg or a placebo. Patients had a baseline cardiac MRI done, and then the exposure was 6 months. They had a follow-up MRI at the end of 6 months. And the primary outcome measure was a 6-month change in left ventricular mass index from baseline to 6 months between the two groups. Dr. Greg Hundley: Very nice. And so , Subodh, can you describe for us now, what did you find? What were your study results? Dr. Subodh Verma: So, first and foremost, what we found in terms of baseline characteristics was that we enrolled a population of people with a mean age of around 60 with a BMI of around 30 kg/m2, predominantly men, about 80% or so were men. These were patients who did not have significant heart failure. The NT-proBNP at baseline was around 50 pg/mL. The eGFR was around 80 mL/minute, and the vast majority of these patients actually had a history of hypertension. Of course, none of them had diabetes by definition. The hemoglobin A1C was around 5.8%. Now what we found was, despite the fact that we went after patients who we thought would be enriched for a baseline increase in LV mass indices, the baseline LV mass index was mildly elevated, was around 63 g/m2. And over the course of 6 months, we did not find any significant difference in terms of LV mass regression between the placebo and empagliflozin groups. In fact, the adjusted treatment effect was minus 0.30 g/m2, which was not statistically significant. No other differences were found in terms of other indices of a remodeling, including left ventricular and diastolic or end systolic volume indices or in terms of left ventricular ejection fraction. There was a 2% increase in ejection fraction, and the p-value for that was 0.07, but really was not statistically significant. Dr. Greg Hundley: And very nice. And realizing that women may have smaller LV masses, any stratified analysis that evaluated effects on men versus women? And then what about, perhaps in the higher quartile versus lower quartile, of age? Dr. Subodh Verma: Right. So, Greg, we actually did look at various subgroups and covariates, including gender, including age. And age or gender did not really influence the overall result that we obtained. There was really a neutral result in empagliflozin, irrespective of these 2 covariates. We also looked at baseline blood pressure, baseline NT-proBNP, LV mass indices, the presence or absence of heart failure, chronic kidney disease. So for the covariates that we have evaluated over a short term of 6 months in this relatively low risk population, we did not find any heterogeneity the result, per se. Dr. Greg Hundley: Very good. Well, Subodh, thank you so much for that beautiful presentation. And listeners, now we're going to turn to our guest editor, Dr. Chris Granger. And Chris is an expert in the field of heart failure. Also, a lot of familiarity with HFpEF, which sounds a little bit, we're looking at precursors. We don't have HFpEF yet, but maybe trying to inhibit this from happening using empagliflozin. How do you put these results in the context with other studies that have emphasized utilizing SGLT2 inhibitors in patients with sort of a preserved ejection fraction and absence of diabetes? Dr. Christopher Granger: Yeah. Well thanks, Greg. And again, congratulations, Subodh, to your study. And I think you framed some of the context here as these drugs, the SGLT2 inhibitors, as being transformative, which I think is exactly right. And it's such a fascinating story. Right? These drugs, which we thought originally, with their cause of glucose spilling in the urine, and a modest decrease in blood glucose, might have a role for modestly improving glucose control in diabetes. And low and behold, they've turned out to be one of the great stories I think in recent, across all of medicine, in terms of their consistent and substantial improving clinical outcomes for patients with heart failure, with diabetes and cardiovascular disease, and now even kidney protection, and much broader implications. And their well tolerated, and they don't have dose titration. So there's some practical appeal to this class of drugs in terms of their benefits, in terms of clinical outcomes. But we're left with having this amazing evidence-based generated without really understanding why are these drugs so effective? And what are they doing? And you've provided, I think, an important piece to the puzzle. We did have the data from patients with diabetes and heart failure, with diabetes and left ventricular hypertrophy, that there is a modest reduce in LV mass with SGLT2 inhibitors. And what you've shown is that for patients that with mild LVH, with risk for LVH, that we simply don't see a substantial reduction in LV mass with the use of these drugs. So I think that provides this evidence that that's not a major cause of benefit, at least in this earlier phase of development of heart failure. And I think it really underscores the fact that there's a lot of work to do still to understand. We know that the renal effects are obvious place that these drugs have such an important benefit. And then the linkage of renal disease and cardiac performance is one of the areas, I think, that's a very exciting aspect of a probable contribution of the mechanism of these drugs. But I think in the end, we're left with still not really understanding why these drugs are so beneficial. But understanding that, I think, will be important, both for opening new avenues of targeting pathways, as well as being able to tell the clinical community, okay, you have these important benefits, but people do want to also know why are we seeing these benefits. Dr. Greg Hundley: Very nice. Well, listeners, we're going to turn back to Dr. Verma here. Subodh, what do you see is the next study to be performed in this sphere of research? Dr. Subodh Verma: Well, first, my thanks to Professor Granger, Chris, for handling this paper and for his very thoughtful comments. And he's absolutely right. We have such wonderful clinical data, and these results, of course, should not in any way take away from the importance of using empagliflozin or other SGLT2 inhibitors in the prevention of heart failure in people with diabetes, or in the treatment of HFpEF or HFrEF. But we're struggling with trying to understand what is the dominant mechanism of action here. And, in the previous precursor to EMPA-HEART 2, we did EMPA-HEART 1 in people with diabetes, and we saw a modest effect that was statistically significant of reduction in LV mass index. And we did not see this, of course, in a lower risk population without diabetes. And that tells me that remodeling may be occurring to a modest effect, it may require a longer time to actually show its benefits, but that this is unlikely a dominant sort of mechanism through which these drugs are working. And I do share Chris's thoughts that one of the key mechanisms of benefit that needs to be further explored is looking at the renal cardiac axes. We know that these drugs are profoundly renal protective, and that the benefits may actually be secondary to improvements in renal hemodynamics, improvements in renal function. And I think that is a population that needs to be, that's a mechanism that needs to be studied further. So I think the next generation of translational mechanistic studies need to really tease out the renal cardiac axes, maybe tease out populations that are at risk but have more significant left ventricular hypertrophy, maybe evaluate patients for a longer duration of treatment, or select people who truly have significant hypertension at baseline. I think those are groups and questions that need further exploration. And, of course, the translational science needs to be also studied in the context of larger completed clinical trials, where biomarkers are currently available and they can be linked, of course, to the outcomes in those trials. So those are some of my thoughts as to where the field could move towards. Dr. Greg Hundley: Very nice. And Chris, do you have anything to add? Dr. Christopher Granger: Subodh, I think that was a great summary. And I might just make a comment on the other end of the spectrum. That is, we have these drugs and the evidence of their benefit, and yet they're grossly underused in the populations that have proven to have benefit. Now it takes some time to educate, to get people familiar with, and get them to integrate these treatments into practice, but there's an enormous opportunity, and I think there is a linkage here. I think when people understand the mechanism, and when they're thoughtful about how these drugs may be working, that that really helps to make the case that the drug should be used, and that people are on board with using them. So I think there's this linkage here, there's the need to both better understand mechanism, and there's the need to have systems of care where these treatments are integrated to provide the benefit that's been so clearly shown in the randomized trials. Dr. Greg Hundley: Very nice. Well, listeners, we want to thank Dr. Subodh Verma, from St. Michael's University in Toronto, and our guest editor, Dr. Chris Granger, from Duke University in Durham, North Carolina, for bringing this paper highlighting that among people with neither diabetes nor significant heart failure but with risk factors for adverse cardiac remodeling, that SGLT2 inhibition with empagliflozin did not, did not, result in a meaningful reduction in LV mass index after 6 months. Well, on behalf of Carolyn, Peder, and myself, we want to wish you a great week, and we will catch you next week on the run. This program is copyright of the American Heart Association 2023.

VIDEOS: The fight for water | DW Documentary   New study shows Rhodiola rosea root might be beneficial for managing type 2 diabetes University of California at Irvine, August 15, 2022 A team of researchers led by the University of California, Irvine has discovered that treatment with an extract from the roots of the Rhodiola rosea plant might be effective for helping manage type 2 diabetes, showing promise as a safe and effective non-pharmaceutical alternative. The study, recently published online in Scientific Reports, found that in a mouse model of human type 2 diabetes, Rhodiola rosea lowered fasting blood sugar levels, improved response to insulin injections, modulated the composition of bacteria in the gastrointestinal tract and decreased several biomarkers of inflammation. The team utilized a genetically engineered mouse model that develops obesity, insulin resistance and high blood sugar, similar to advanced human type 2 diabetes, to test whether Rhodiola rosea could improve glucose homeostasis. In the study, cohorts of age-matched male and female mice were randomly assigned to one of two groups: control, which received water, or experimental, which received Rhodiola rosea extract. (NEXT) Meta-analysis concludes benefits for selenium supplementation in cognitively impaired individuals Instituto de Pesquisa Pelé Pequeno Príncipe (Brazil), August 15 2022.  A systematic review and meta-analysis published  in Nutrients found that supplementing with selenium was associated with improved levels of the mineral and the antioxidant enzyme glutathione peroxidase, as well as better cognitive function among patients with mild cognitive impairment (MCI) or Alzheimer disease (AD).  “For the first time, our study demonstrated, through a systematic review and meta-analysis, the possible benefits of selenium supplementation on selenium levels in patients with MCI or AD, as well as on markers of oxidative stress and on cognitive test performance,” Meire Ellen Pereira and colleagues wrote. Among studies that evaluated the effects of selenium without other nutrients, selenium measured in plasma, serum, red blood cells or cerebrospinal fluid increased among participants who received the mineral while remaining essentially the same or lower in the control groups. The meta-analysis determined that supplementing with selenium increased selenium levels by an average of 4 times in plasma, 1.88 times in serum, 3.73 times in red blood cells and 2.18 times in cerebrospinal fluid.  (NEXT) Skip the elevator: A 15-minute walk can help your brain fight off Alzheimer's German Center for Neurodegenerative Disease, August 15 2022 Older people can stave off Alzheimer's disease with a daily 15-minute walk or other physical activities, according to new research. Researchers in Germany say moderate physical activity boosts all areas of the brain, especially those involved in memory. Staying active also benefits people over 70 the most. They see the biggest increase in grey matter, compared to their “couch potato” peers. “Our study results indicate that even small behavioral changes, such as walking 15 minutes a day or taking the stairs instead of the elevator, may have a substantial positive effect on the brain and potentially counteract age-related loss of brain matter and the development of neurodegenerative diseases. In particular, older adults can already profit from modest increases of low intensity physical activity.” (NEXT) Antioxidants in fruit boosts immunity and protects thymus gland  Scripps Research Institute, August 8, 2022 Eating fruit and vegetables or taking antioxidant supplements may combat one of the most harmful aspects of aging by protecting a vital immune system organ, research suggests. Scientists demonstrated how ageing sabotaged the thymus gland, weakening the immune system and putting the elderly at greater risk of infection. But the irreversible damage could be reduced by the action of antioxidants such as vitamin C. Experiments showed that antioxidants – which are abundant in many fruits and vegetables – cut down the destruction wrought by a highly reactive by-product of normal metabolism. In studies on mice, animals given vitamin C and another antioxidant used in human medicine experienced significantly less age-related deterioration of the thymus. US lead scientist Dr Howard Petrie, from the Scripps Research Institute in San Diego, California, said: “The thymus ages more rapidly than any other tissue in the body, diminishing the ability of older individuals to respond to new immunologic challenges, including evolving pathogens and vaccines. Its function is to manufacture T-cells, essential immune system cells in the front-line of the body's defences against harmful foreign invaders and cancer. (NEXT) Modern Processed Diets Are Coding DNA and Gut Bacteria To Pass On Poor Immune Functions To Our Children Yale University and Erlangen-Nuremberg University, August 6, 2022 A team of scientists from Yale University in the U.S and the University of Erlangen-Nuremberg, in Germany, has said that junk food diets could be partly to blame for the sharp increase in autoimmune diseases such as multiple sclerosis, including alopecia, asthma and eczema. The new stark warnings come in a review published in Nutrition Journal, which analysed the impact that the modern Western diet has on immune function and risk of ill-health related to poor immunity and inflammation."While today's modern diet may provide beneficial protection from micro- and macronutrient deficiencies, our over abundance of calories and the macronutrients that compose our diet may all lead to increased inflammation, reduced control of infection, increased rates of cancer, and increased risk for allergic and auto-inflammatory disease," warned Myles in his review. Each person harbors a unique and varied collection of bacteria that's the result of life history as well as their interactions with the environment, diet and medication use. Western diet and lifestyles consisting of fast and processed foods are leading to a lower diversity of bacteria in the gut, say researchers. Of potentially greatest concern, our poor dietary behaviours are encoded into both our DNA scaffolding and gut microbiome, and thus these harmful immune modifications are passed to our offspring during their most critical developmental window. (NEXT) The aging heart accumulates mutations—while losing the ability to repair them Children's Hospital Boston, August 12, 2022 Why does the risk of heart disease go up as we age? Known risk factors such as hypertension or high cholesterol don't explain all cases. A first-of-its-kind study from Boston Children's Hospital now shows that the cells that make up our heart muscle accumulate new genetic mutations over time—while losing the ability to repair them. The findings were published in the journal Nature Aging. The research team, led by Sangita Choudhury, Ph.D., and August Yue Huang, Ph.D., in the Division of Genetics and Genomics at Boston Children's, sequenced the entire genomes of 56 individual heart muscle cells, known as cardiomyocytes, from 12 people across the age spectrum—from infancy to 82 years—who had died from causes unrelated to heart disease.

Researchers study preventing cancer and diabetes with the maqui berry NOVA Southeastern University of Florida, May 27, 2021 Aristotelia chilensis, also known as maqui berry, is a fruit-bearing shrub native to South America.  According to a study published in the journal Phytochemical Analysis, maqui berries are rich in anthocyanins, which give the fruits their dark purple color. Anthocyanins are plant pigments that possess many remarkable biological properties, such as antioxidant, anti-inflammatory, anti-viral and anti-cancer activities. In a recent study, researchers at NOVA Southeastern University in Florida discussed the potential of Chilean maqui berry for use as a nutritional supplement that can help treat hyperinsulinemia and related diseases. Hyperinsulinemia, or higher-than-normal insulin levels, is often caused by insulin resistance, which is said to be the precursor to diabetes. Chronic hyperinsulinemia also promotes cancer growth by allowing insulin to exert its oncogenic effects, which include enhancing growth factor-dependent cell proliferation, among others. The researchers discussed how Chilean maqui berry can help with insulin resistance and reduce cancer risk in an article published in the journal Food Science and Human Wellness. The medicinal benefits of Chilean maqui berry Researchers have long considered nutritional supplementation to be a possible alternative or adjunct treatment to conventional therapies for common ailments and diseases. According to recent studies, maqui berries can reduce postprandial insulin levels by as much as 50 percent and are just as effective as metformin at increasing insulin sensitivity and stabilizing blood glucose levels. Maqui berries’ mechanism of action involves inhibiting sodium-dependent glucosetransporters in the small intestine and slowing the rate of entry of glucose in the bloodstream. Thanks to these actions, maqui berries can effectively reduce the likelihood of blood sugar spikes and prevent the corresponding rise in insulin levels that follows.  At the same time, maqui berries contribute to cancer prevention since chronically high blood glucose levels — besides chronic hyperinsulinemia — are also linked to the development of cancer. In fact, numerous studies have shown that diabetics and prediabetics have an elevated risk of developing cancerous growths. Based on the findings of previous studies, the researchers believe that consistent supplementation with Chilean maqui berries could indirectly reduce the risk of cancer and other diseases that are promoted by hyperglycemia (high blood sugar) and hyperinsulinemia.     Studies reveal that social isolation and quarantine throughout the COVID-19 pandemic may have a detrimental impact on physical and mental health of people living with pre-existing conditions University of Naples (Italy) and Teva Pharmaceuticals, May 30, 2021   Abstract 803: Impact of social isolation and quarantine on the course of diabetes mellitus and its complications during Covid 19 pandemic in Adjara Region Country of Georgia Abstract 1337: Psychological distress in patients with hypocortisolism during mass quarantine for Covid-19 epidemic in Italy Studies reveal that social isolation and quarantine throughout the COVID-19 pandemic may have a detrimental impact on people living with pre-existing conditions.  Social isolation and quarantine can have a detrimental impact on physical and mental health of people living with pre-existing conditions, according to two studies being presented at the 23rd European Congress of Endocrinology (e-ECE 2021)  The studies bring together research on the impact of social isolation and quarantine for people living with diabetes in the Adjara Region of Georgia, and on patients with hypocortisolism in Italy. Both studies reported that social isolation during the pandemic caused significant psychological and/or physical distress on the observed individuals.  Data from the first study revealed that the impact of quarantine on people living with diabetes in the Adjara Region caused blood pressure (BP) levels to increase in 88.2% of patients with 50% of these cases resulting in high BP hospitalisation. In addition to these physical factors, increased feelings of anxiety and fear were observed on 82% of patients. In the second study, patients with hypocortisolism experienced increased anxiety and depression, associated with a dissatisfaction feeling of self and a reduced resiliency, when compared with Italian healthy controls. As these are all contributing factors to overall health deterioration, these findings suggest further research is required to allow patients with pre-existing conditions to remain fit and healthy during the current pandemic. In the Adjara Region study, Dr Liana Jashi and the research team disseminated an online questionnaire and collected answers from 16 endocrinologists and 22 family and general practice doctors. The study confirmed the negative, indirect effects social isolation and quarantine had on people living with diabetes. It reported a list of negative effects such as the reduced access to medical care, weight gain and increased cigarette and alcohol consumption. Physical activity decreased by 29.8%, a vital preventative to further physical and psychological problems.  "This study highlights that people living with diabetes require greater support during pandemics to maintain exercise and protect their physical and mental health. National health services should use these data and future studies to implement better social care around supporting people with pre-existing conditions," commented Dr Jashi. In the second study, Dr Chiara Simeoli at the University of Naples reported data collected during the last three weeks of the mass quarantine lasted 2 months in Italy, in a web-survey-based, multicenter, case- control research involving 12 different Italian centres. The study confirmed that a large cohort of 478 patients with hypocortisolism, and particularly, 363 with adrenal insufficiency and 115 with congenital adrenal hyperplasia, adequately treated with glucocorticoids, showed higher anxiety and depression, associated with a dissatisfaction feeling of self and a reduced resiliency, when compared with Italian healthy controls, suggesting the detrimental impact of social isolation on mental health of these patients, particularly frail and vulnerable to infections and stress. Moreover, patients with adrenal insufficiency reported a worse quality of life than patients with congenital adrenal hyperplasia.  "These findings confirmed that beyond the huge impact on physical health, COVID-19 epidemic, social isolation and mass quarantine represent significant psychological stressors, causing severe effects on mental health, even more on people with pre-existing conditions. An empowerment of psychological counselling for these vulnerable patients during COVID-19 should be considered by national health-care services," adds Dr Simeoli.  Both studies indicate that additional larger studies over a longer period of time are needed for further investigation.       Researchers discover link between local oxygen depletion in the brain and Alzheimer's disease University of Seville (Spain), May 24, 2021 The study, published in the journal Nature Aging and led by the laboratories of Dr. Alberto Pascual (CSIC), from the Neuronal Maintenance Mechanisms Group, and Prof. Javier Vitorica (University of Seville/CIBERNED) of the Physiopathology of Alzheimer's Disease Group at IBiS, demonstrates for the first time that low oxygen levels in the so-called senile plaques in the brain reduces the immune system's defensive capacity against the disease. The study also suggests that this lack of oxygen in the brain enhances the action of disorders associated with Alzheimer's disease that are characterized by low systemic oxygen levels, such as atherosclerosis and other cardiovascular diseases. What happens in the brain? A characteristic feature of Alzheimer's patients is the accumulation of highly toxic substances in their brains, known as senile plaques. The brain has an immune system whose main component are the microglial cells, which were first described and named 100 years ago by Pío del Río Hortega, a disciple of Ramón y Cajal. In the absence of damage, these cells facilitate the neurons' function. In response to Alzheimer's disease, microglia defend neurons by surrounding senile plaques, preventing their spread in the brain and decreasing damage. Alzheimer's disease is aggravated by other pathologies, such as cardiovascular diseases, which cause a decrease in oxygen levels in the body. This study has revealed reduced oxygen levels around senile plaques, compromising microglial activity (Image, center). When this is compounded by reduced oxygen supply to the brain due to other systemic pathologies, the microglia are unable to provide protection and there is an increase in the pathology associated with the disease. Relevance Alzheimer's disease is the leading cause of dementia in Spain and around the world. In Spain, its incidence is increasing dramatically as the population ages. Unfortunately, the origin of the disease remains unknown. The mechanism proposed in this study is mediated by the expression of the HIF1 molecule, whose discoverers received the Nobel Prize in Physiology or Medicine in 2019. Increased HIF1 levels compromise the mitochondrial activity of microglial cells and limit their protective capacity against disease. This study opens new lines of research to improve the metabolic capacity of microglia, which would enable a sustained response over time against the disease. Indirectly, the study supports previous work highlighting the importance of maintaining good cardiovascular health for healthy aging.   Effect of different doses of melatonin on learning and memory deficit in Alzheimer model Guilan University of Medical Sciences (Iran), May 21, 2021   According to news reporting out of Rasht, Iran, research stated, “Alzheimer Disease (AD) is an age-related neurodegenerative disorder with a progressive impairment of cognitive function. The pineal gland hormone melatonin (MEL) has been known as a protection agent against AD.” Our news reporters obtained a quote from the research from Guilan University of Medical Sciences: “However, the effect of melatonin in various doses is inconsistent. In this study, we aimed to investigate two doses of MEL on learning and memory in the amyloid-beta (Ab)-induced AD in the rats. Forty-eight male Wistar rats were used in the experiment and randomly divided control, sham, vehicle, AD, AD+MEL10 mg/kg, and AD+MEL 20 mg/kg groups. Intracerebroventricular injection of Ab1-42 was used to develop the animal model of AD. Also, MEL-treated groups received an intraperitoneal injection of MEL for 4 next weeks. The Morris Water Maze (MWM) and Passive Avoidance Learning (PAL) tests were used to examine animals’ learning and memory. The brain of animals was removed for immunohistochemistry for anti- Amyloid Precursor Protein (APP). Intra-peritoneal injection of MEL significantly improve learning and memory in MWM (P=0.000) and PAL test (P=0.000), but there were no significant changes in the two groups that received the melatonin (P>0.05). Histopathological analysis revealed that the clearance of APP deposition in the AD+MEL20 group was considerable compared with the AD+MEL10 group (P=0.000).” According to the news editors, the research concluded: “Our findings indicate that 10 and 20 mg/kg doses of melatonin have similar results on learning and memory in the AD model. But 20 mg/kg of melatonin has significantly more effect on the clearance of APP deposition.”     Effects of flaxseed on blood pressure, body mass index, and total cholesterol in hypertensive patients: A randomized clinical trial Lorestan University of Medical Sciences (Iran), May 25, 2021 Objectives Given the antioxidant properties of flaxseed and its biologically active ingredients, this study was conducted to determine the effects of flaxseed supplementation on body mass index (BMI), blood pressure, and total cholesterol levels in patients with hypertension. Methods In this triple-blind clinical trial, 112 patients, with an age range of 35 to 70 years, were randomized to 2 groups receiving 10 g (n=45) and 30 g (n=45) of flaxseed supplementation and 1 group receiving placebo (n=45) for 12 weeks by stratified block randomization. They were evaluated in terms of systolic (SBP) and diastolic blood pressure (DBP), BMI, and total serum cholesterol. Physical activity was measured using the International Physical Activity Questionnaire–Short Form (IPAQ–SF) and food intake was assessed using the Food Frequency Questionnaire (FFQ). The data were analyzed with SPSS, version 22, using the chi-square, Kruskal–Wallis, repeated measures analysis, ANOVA, and ANCOVA tests. Results The interaction effects among the study groups and time on the mean SBP (p = 0.001), DBP (p = 0.001), total cholesterol level (p = 0.032), and BMI (p < 0.001) were significant. During the study, the 30-g group achieved the best results, so that a 13.38-unit decrease in SBP was observed compared to a 1.72 unit increase in the placebo group and a 5.6-unit decrease in DBP was measured compared to a 2.39 unit increase in the placebo group. BMI decreased by 0.86 units compared to 0.06 units in the placebo group. Total cholesterol also decreased by 20.4 units compared to 11.86 units in the placebo group. Conclusion The results of this study showed that flaxseed can be effective in reducing blood pressure, total cholesterol, and body mass index in hypertensive patients in a twelve-week period.     Study: Don't count on caffeine to fight sleep deprivation Michigan State University, May 27, 2021 Rough night of sleep? Relying on caffeine to get you through the day isn't always the answer, says a new study from Michigan State University. Researchers from MSU's Sleep and Learning Lab, led by psychology associate professor Kimberly Fenn, assessed how effective caffeine was in counteracting the negative effects of sleep deprivation on cognition. As it turns out, caffeine can only get you so far. The study -- published in the most recent edition of Journal of Experimental Psychology: Learning, Memory, & Cognition -- assessed the impact of caffeine after a night of sleep deprivation. More than 275 participants were asked to complete a simple attention task as well as a more challenging "placekeeping" task that required completion of tasks in a specific order without skipping or repeating steps. Fenn's study is the first to investigate the effect of caffeine on placekeeping after a period of sleep deprivation. "We found that sleep deprivation impaired performance on both types of tasks and that having caffeine helped people successfully achieve the easier task. However, it had little effect on performance on the placekeeping task for most participants," Fenn said. She added: "Caffeine may improve the ability to stay awake and attend to a task, but it doesn't do much to prevent the sort of procedural errors that can cause things like medical mistakes and car accidents."  Insufficient sleep is pervasive in the United States, a problem that has intensified during the pandemic, Fenn said. Consistently lacking adequate sleep not only affects cognition and alters mood, but can eventually take a toll on immunity.  "Caffeine increases energy, reduces sleepiness and can even improve mood, but it absolutely does not replace a full night of sleep, Fenn said. "Although people may feel as if they can combat sleep deprivation with caffeine, their performance on higher-level tasks will likely still be impaired. This is one of the reasons why sleep deprivation can be so dangerous." Fenn said that the study has the potential to inform both theory and practice.  "If we had found that caffeine significantly reduced procedural errors under conditions of sleep deprivation, this would have broad implications for individuals who must perform high stakes procedures with insufficient sleep, like surgeons, pilots and police officers," Fenn said. "Instead, our findings underscore the importance of prioritizing sleep."     Parkinson's disease more likely in people with depression, study suggests Umea University (Sweden), May 21 2021     People with depression may be more likely to develop the movement disorder Parkinson's disease, according to new research published in Neurology.   According to the authors of the study, depression is more common in people with Parkinson's disease than those without the movement disorder. "We saw this link between depression and Parkinson's disease over a timespan of more than 2 decades, so depression may be a very early symptom of Parkinson's disease or a risk factor for the disease," says study co-author Prof. Peter Nordström, at Umeå University in Sweden. Parkinson's disease is a progressive disorder of the nervous system that affects how a person moves, including how they speak and write. As well as problems with movement, Parkinson's disease can also cause cognitive problems, neurobehavioral problems and sensory difficulties. The authors of the study state that depression is more common in patients with Parkinson's disease than in members of the general population. The mood disorder has a major influence on health-related quality of life and could also be involved in more rapid deterioration of cognitive and motor functions. However, few studies have investigated this association for periods of longer than 10 years, with any long-term findings so far inconclusive. For the study, the researchers used a cohort consisting of all Swedish citizens aged 50 years and above as of December 31st, 2005. From this group, they then took the 140,688 people diagnosed with depression . These individuals were each matched with three control participants (a total of 421,718 controls) of the same age and sex who had not been diagnosed with depression. The participants were then followed for up to 26 years. A total of 1,485 people with depression (1.1%) developed Parkinson's disease during this time, compared with 1,775 of those who did not have depression (0.4%). On average, Parkinson's disease was diagnosed 4.5 years after the beginning of the study, with the likelihood of the disorder developing decreasing over time. No sibling link found for depression and Parkinson's disease The researchers calculated that participants with depression were 3.2 times more likely than those without depression to develop Parkinson's disease within a year of the study beginning. After 15-25 years, the researchers found participants with depression were almost 50% more likely to develop the condition. If a participant's depression was severe, their likelihood of developing Parkinson's disease was also higher. For example, those who had been hospitalized for depression five or more times were 40% more likely to develop Parkinson's disease than participants who had been hospitalized for depression just once. In addition to these observations, the researchers examined siblings. No link was found between one sibling having Parkinson's disease and the other having depression. "This finding gives us more evidence that these two diseases are linked," says Prof. Nordström. "If the diseases were independent of each other but caused by the same genetic or early environmental factors, then we would expect to see the two diseases group together in siblings, but that didn't happen." The authors suggest there are a number of mechanisms that could explain their findings. Depression or antidepressive treatment could increase the risk of Parkinson's disease, depression could be an early symptom of Parkinson's disease, or that the two conditions could share environmental causative factors. In the paper, the authors acknowledge that they are unable to evaluate the potential role of substances used in antidepressive treatment as risk factors for Parkinson's disease. The study is an observational one and cannot determine causation. "Our findings suggest a direct association between depression and subsequent [Parkinson's disease], supported by a time-dependent hazard ratio, a dose-response pattern for recurrent depression, and a lack of evidence for coaggregation among siblings," the authors conclude. "Given that the association was significant over more than two decades of follow-up, depression may be a very early prodromal symptom of or a causal risk factor for [Parkinson's disease]." Elsewhere, a study published in December previously suggested that users of methamphetamine are at three times more risk of getting Parkinson's disease than people who do not use illegal drugs.
