Meditation was linked to lower cardiovascular risk in a data analysis by Veterans Affairs researchers and colleagues.
The results appeared online June 30 in the American Journal of Cardiology.
Previous studies have suggested that meditation may have beneficial effects on a number of conditions. A 2017 American Heart Association scientific statement suggests that meditation may be of benefit for cardiovascular risk reduction. Data show that it may help with blood pressure, cholesterol level, quitting smoking, and overall cardiovascular health. However, this connection is far from definitive. By using a large national database with many participants, the authors of the new study sought further evidence on how meditation impacts cardiovascular risk.
Lead researcher Dr. Chayakrit Krittanawong--of the Michael E. DeBakey VA Medical Center, Baylor College of Medicine, and the Icahn School of Medicine at Mount Sinai--and his colleagues studied data from the National Health Interview Survey, conducted annually by the National Center for Health Statistics. It collects information on a wide range of health topics from a nationally representative sample.
The researchers looked at data on more than 61,000 survey participants. Of those, almost 6,000 (nearly 10%) said they participated in some form of meditation.
The researchers found that people who meditated had lower rates of high cholesterol, high blood pressure, diabetes, stroke, and coronary artery disease, compared with those who did not meditate.
The greatest difference was in coronary artery disease. Those who meditated were 51% as likely as those who didn't to have the disease. The prevalence of other cardiovascular risks in the meditation group compared with the non-meditation group was 65% for high cholesterol, 70% for diabetes, 76% for stroke, and 86% for high blood pressure.
The researchers controlled for other factors connected to cardiovascular risk, such as age, sex, cigarette smoking, and body mass index. After adjusting for these factors, the effect of meditation was still significant.
Many types of meditation exist. Most focus on attention and awareness. Meditation has been shown to increase physical and mental relaxation. "I believe in meditation, as it can give us a sense of calm, peace, and stress reduction, leading to improvement of our emotional well-being," explained Krittanawong.
Practicing meditation has been linked to decreased stress, greater mindfulness, and improved psychological health. It may even lead to long-term functional and anatomical changes in the brain. Meditation is also simple, cost-effective, and low-risk.
Krittanawong and colleagues did note several limitations to the study. First, the survey did not capture what type of meditation people were using. Some types of meditation may offer more cardiovascular benefit than others, say the researchers. The survey also did not ask about the duration or intensity of that meditation. It is possible that those who practice longer and more frequently will get more benefit, but the study cannot measure these effects.
Also, the researchers cannot definitively say that meditation directly decreases cardiovascular risk. It could be that people who are in better cardiovascular health to begin with are more likely to practice meditation, rather than the other way around.
Other life activities might also obscure the link between meditation and cardiovascular health. The researchers found factoring in alcohol consumption and physical activity lowered the significance of the relationship between meditation and cardiovascular risk.
Considering all these factors, the researchers concluded that meditation is "probably" associated with lower prevalence of cardiovascular risk. Krittanawong notes that, while the results suggest that meditation can improve cardiovascular health, "we would need a powerful study such as a clinical trial to determine whether meditation could benefit cardiovascular health in veterans."
Meanwhile, the study adds to a growing body of research on the potential benefits of meditation, they say.

Pickled capers activate proteins important for human brain and heart health

New study reveals how a compound found in capers regulates proteins that control important bodily processes

Irvine, CA - July 13, 2020 - A compound commonly found in pickled capers has been shown to activate proteins required for normal human brain and heart activity, and may even lead to future therapies for the treatment of epilepsy and abnormal heart rhythms.
Researchers from the University of California, Irvine School of Medicine have discovered that a compound named quercetin, commonly consumed when eating capers, can directly regulate proteins required for bodily processes such as the heartbeat, thought, muscular contraction, and normal functioning of the thyroid, pancreas and gastrointestinal tract.
Published in Communications Biology, the discovery was made by the laboratory of Geoffrey Abbott, PhD, a professor in the Department of Physiology and Biophysics at the University of California, Irvine School of Medicine. Kaitlyn Redford, a graduate student in the Abbott Lab, was first author of the study titled, "The ubiquitous flavonoid quercetin is an atypical KCNQ potassium channel activator."
The Abbott Lab found that quercetin, a plant-derived bioflavonoid, modulates potassium ion channels in the KCNQ gene family. These channels are highly influential in human health and their dysfunction is linked to several common human diseases, including diabetes, cardiac arrhythmia, and epilepsy.
The study revealed that quercetin modulates the KCNQ channels by directly regulating how they sense electrical activity in the cell, suggesting a previously unexpected mechanism for the therapeutic properties of capers. The mechanism may extend to other quercetin-rich foods in our diet, and quercetin-based nutritional supplements.
"Now that we understand how quercetin controls KCNQ channels," said Abbott, "future medicinal chemistry studies can be pursued to create and optimize quercetin-related small molecules for potential use as therapeutic drugs."
The Abbott Lab screened plant extracts for the ability to alter activity of KCNQ channels and found that one percent extract of pickled capers activated channels important for normal human brain and heart activity. Further studies revealed the molecular mechanism - quercetin from the caper extract binds to a region of the KCNQ channel required for responding to electrical activity, and in doing so, tricks the channel into opening when it would normally be closed.
"Increasing the activity of KCNQ channels in different parts of the body is potentially highly beneficial," said Abbott. "Synthetic drugs that do this have been used to treat epilepsy and show promise in preventing abnormal heart rhythms."
Archaeological evidence for human caper consumption dates back as far as 10,000 years, according to archaeological findings from Mesolithic soil deposits in Syria and late Stone Age cave dwellings in the Greece and Israel. Capers have traditional been used as folk medicine for hundreds if not thousands of years and are in current use or study for their potential as anti-cancer, anti-diabetic and anti-inflammatory properties, and their possible circulatory and gastrointestinal benefits.

Study links attraction to 'tyrannical' leaders to dysfunctional family dynamics

Adolescent family conflict could play a role in the types of leaders people follow as adults
SAN FRANCISCO STATE UNIVERSITY
Ever wonder how some leaders in business or politics who appear selfish, manipulative and domineering still manage to amass a following? A recent study in the Journal of Leadership & Organizational Studies by San Francisco State University Assistant Professor of Management Dayna Herbert Walker found a connection between a person's childhood family environment and the types of leaders they're drawn to as grown-ups.
Using data from the Fullerton Longitudinal Study, a long-term study that began tracking families in 1979, Herbert Walker and three other researchers noticed a correlation between adolescents who reported a high level of conflict at home and those who later identified socially undesirable traits as ideal leadership qualities.
"We see it all the time -- where the obnoxious leader rises to the top, but we don't know much about why," Herbert Walker said. "Tyrants, whether they be in the boardroom or in politics, wouldn't have the power they do if followers didn't support them. We often look to leaders to explain leadership, but we should also be looking to followers."
The survey, which tracked 130 individuals at various points of their life, gave researchers details about participants' home lives and the leadership traits they valued most. Researchers studied data gathered in 1996, when participants were 17 years old. Two decades later, as part of another round of data collection for the Fullerton Longitudinal Study, researchers asked the same individuals questions about ideal leadership qualities.
The 1996 survey asked participants about their family dynamics, such as whether people at home raised their voices, criticized one another or were physically violent. Twenty years later, those respondents were asked to measure on a scale whether 10 qualities researchers defined as tyrannical (domineering, pushy, dominant, manipulative, power-hungry, conceited, loud, selfish, obnoxious and demanding) were characteristics present in their image of an ideal leader.
"It's critical that we asked about ideal leadership and not just leadership in general," Herbert Walker said, "because we really wanted to get at a person's favored leadership image, the characteristics they ideally want to see in their leaders."
Herbert Walker and the study's other authors then compared the data from 2016 and 1996 and found a strong positive connection between those who reported living with a high level of conflict at home and those whose ideal image of a leader possessed these negative traits. A person who experiences high conflict in adolescence is 20% more likely than chance to prefer a tyrannical model of leadership, controlling for other known factors that shape leadership preferences like sex and personality. When adolescent family environments contain a high amount of dysfunctional conflict, it's likely that some tyrannical behavior is on display and that role modeling can shape the way a person views leadership, Herbert Walker explains.
The findings shed new light on what ideal leadership can look like for some followers, illuminating why some of us are drawn to tyrants despite their harsh approach.
Herbert Walker says another group could learn important lessons from the findings, as well: bad bosses. For instance, a manager who believes leaders should be overbearing or manipulative could end up acting out those traits.
"The first step is getting them to question their assumptions about why they do what they do," she said. "Maybe they'll realize that they believe this, because that's how their dad behaved and he was successful in business. And so they believe that's how they're supposed to act."

PHILADELPHIA (July 14, 2020) - As a rapid influx of patients overwhelmed health systems during the coronavirus pandemic, palliative nurses played dual roles supporting patients, patient families, and colleagues. Two researchers at the University of Pennsylvania School of Nursing (Penn Nursing) are among those detailing the important role palliative care has in responding during the COVID-19 pandemic and in future public health crises.
Advancing Palliative Care During COVID-19 Pandemic
As history proves, nursing science and scholarship have consistently improved patient care and outcomes throughout history's most daunting times. Today, nurse scientists and scholars have a unique opportunity to translate lessons learned about the shortcomings of health care during COVID-19 into strategic actions and investigations that reflect the needs of a rapidly changing society.
"Investing in the global culture of palliative care scholarship for nurses and health professionals across practice domains is one of the most accessible approaches to ensuring health care reflects a person-centered and value concordant ethos in the face of a future public health crisis," write William E. Rosa, PhD, MBE, NP-BC, FAANP, FAAN, a Robert Wood Johnson Foundation Future of Nursing Scholar and Salimah H. Meghani, PhD, MBE, RN, FAAN, Professor of Nursing & Term Chair of Palliative Care and Associate Director of the NewCourtland Center for Transitions and Health. They are two of the co-authors of a guest editorial in the Journal of Nursing Scholarship.
Their editorial provides a palliative care perspective on advancing patient care globally during COVID-19 and beyond. It provides recommendations to develop a research agenda rooted in a palliative care philosophy and ethos to meet the current global population health needs and anticipated future health crises.
The editorial, "Opportunities for Nursing Science to Advance Patient Care in the Time of COVID-19:A Palliative Care Perspective" is available online. Co-authors of the editorial include Patricia W. Stone, PhD, RN, FAAN, CIC of the Columbia University School of Nursing; and Betty R. Ferrell, PhD, RN, FAAN, FPCN, of the City of Hope Medical Center.
Optimizing the Palliative Nursing Role
Palliative nurses play a primary and significant role in supporting the broader health care system. As the pandemic continues to evolve, it has become clear that the work of the palliative nurse is indispensable as issues surrounding serious illness, dying, and death are no longer taboo but have become continuous threads of daily mainstream media, politics, and policy-making.
"This crisis offers an opportunity to reimagine the benefits of full palliative care integration to mitigate the effects of this and future health crises for patients, families, and communities," write Rosa and Meghani, two of the co-authors of an article in the Journal of Hospice & Palliative Nursing.
The authors share how best to leverage and integrate the palliative nursing role throughout health care settings. The article has implications for clinical nurses, nurse practitioners, clinical nurse specialists, and multidisciplinary stakeholders and includes resources for self-care and education.

Robert Graham Center: First steps towards gender parity in academic authorship

Trends in the gender ratio of authorship at the Robert Graham Center
AMERICAN ACADEMY OF FAMILY PHYSICIANS
Researchers affiliated with the Robert Graham Center for Policy Studies in Family Medicine and Primary Care conducted a descriptive bibliometric analysis to determine the gender ratio of scholarly authorship on publications by its researchers between 2008 and 2018. While the average gender ratio of RGC researchers across this period was 46.3 percent female to 56.4 percent male, gender disparities in authorship were much starker. For example, roughly two-thirds of 229 publications listed a male first author, and almost all had at least one male author. While the RGC team recognizes the limitations of a single-case study, their intention is to broaden the discussion about gender parity in authorship among academic medical researchers.

Gemini Observatory's quick reflexes capture fleeting flash

The international Gemini Observatory detects optical afterglow of short gamma-ray burst within hours
ASSOCIATION OF UNIVERSITIES FOR RESEARCH IN ASTRONOMY (AURA)
Rapid follow-up of the optical afterglow from one of the most distant confirmed short gamma-ray bursts (SGRB), thought to be the merger of two neutron stars, is casting new light on these enigmatic objects. The observations, made by the international Gemini Observatory, a Program of NSF's NOIRLab, confirmed the object's distance and placed it squarely in the epoch of cosmic high noon, when the Universe was in its "teenage years" and rapidly forming stars. The appearance of an SGRB so early in the history of the Universe could alter theories about their origin, in particular how long it takes two neutron stars to merge to produce these powerful events. Precisely-localized SGRBs are rare, typically only 7-8 are detected per year, and this is the most distant high-confidence SGRB with an optical afterglow detection.
Researchers have used the 8.1-meter Gemini North telescope to measure the optical afterglow of one of the most distant short gamma-ray bursts (SGRB) ever studied. Thought to result from the merger of two neutron stars, SGRBs are cataclysmic events that are almost unfathomable in terms of their basic properties, emitting huge amounts of energy in about one second [1]. Gemini observations of a new, distant SGRB now suggest that this process could occur surprisingly quickly for some systems -- with massive binary star systems surviving supernova explosions to become neutron star binaries, and the binaries then spiraling together in less than a billion years to create an SGRB. The research will be published in he Astrophysical Journal Letters.
This object, named GRB181123B because it was the second burst discovered on 23 November 2018 -- Thanksgiving night -- was initially detected by NASA's Neil Gehrels Swift Observatory. When the alert of an event from the Swift satellite was broadcast around the world, several telescopes trained their view on it. Within hours, a team from Northwestern University used the Gemini Multi-Object Spectrograph (GMOS), which is also an imager, on the Gemini North telescope on Maunakea in Hawai'i to record the very faint afterglow of the object.
"We took advantage of the unique rapid-response capabilities and exquisite sensitivity of Gemini North and its GMOS imager to obtain deep observations of the burst mere hours after its discovery," said Kerry Paterson of the Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA) at Northwestern University, USA, who led the research team. "The Gemini images were very sharp, and allowed us to pinpoint the location to a specific galaxy."
"This is a wonderful example of time-domain astronomy, involving extremely rapid follow-up of a quickly evolving event," said Hans Krimm of the US National Science Foundation. "Gemini's rapid response was critical to catching this event swiftly, and the optical and infrared data add to the excitement of multi-messenger astronomy -- where observations of light, gravitational waves, neutrinos and cosmic rays come together to tell a compelling story."
Along with the Gemini observations, the team made follow-up observations using the W. M. Keck Observatory in Hawai'i and the Multi-Mirror Telescope (MMT), located at the Fred Lawrence Whipple Observatory on Mount Hopkins in Arizona. The researchers then utilized the Gemini South infrared camera and spectrograph, FLAMINGOS-2, in Chile to obtain a spectrum of the host galaxy to pin down the SGRB's distance. The object was found to be some 10 billion light-years away, making it the second most distant confirmed SGRB, and the most distant high-confidence SGRB with an optical afterglow detection [2]. Compared to the detections of gravitational waves from merging neutron stars in the very nearby Universe, SGRBs are distant analogs.
"The identification of certain patterns in the spectrum, together with the colors of the galaxy from the three observatories, allowed us to precisely constrain the distance and solidify it as one of the most distant SGRBs to date in 16 years of Swift operations," said Paterson.
Rapid follow-up of the burst discovery from Swift was essential. Many SGRBs cannot be observed with a telescope in time to catch the optical light. The light from the afterglow fades quickly and it can take a correspondingly long time for a large, sensitive telescope to interrupt its normal observing plan and move to the new target to begin its follow-up observations.
Once the optical detection of the SGRB was made with Gemini, and its host galaxy was identified, the team was able to determine key properties of the parent stellar population within the galaxy that produced the SGRB.
"Performing 'forensics' to understand the local environment of SGRBs and what their home galaxies look like can tell us a lot about the underlying physics of these systems, such as how SGRB progenitors form and how long it takes for them to merge," said Wen-fai Fong of Northwestern University and co-author on the study. "We certainly did not expect to discover an extremely distant SGRB, as they are very rare and faint, but we were pleasantly surprised! This motivates us to go after every one that we possibly can."
The majority of the 43 high-confidence SGRBs used in the study that have had their distances measured to date have been found closer to home. Distant SGRBs offer a unique way to study the same types of events when the Universe was much younger -- a busy period in the Universe when stars were rapidly forming and galaxies were growing fast [3]. The addition of another very distant SGRB to the population could change astronomers' understanding of these events -- in particular, how long it takes two neutron stars to merge, and the rate of neutron star mergers during this epoch of the Universe's history. "Finding an SGRB so early in the Universe's history suggests that at least some neutron star pairs might need to come together relatively rapidly," according to Fong.
"With the proper telescopic resources and dedicated follow-up facilities, such as the Gemini Observatory, we can open a new era of discovery of distant SGRBs, motivating further follow-up studies of past events and similarly intense follow-up of future ones," said Paterson.
###
Notes
[1] Despite their spectacular nature, the formation pathway to a SGRB is unknown. Astronomers believe they are likely formed from a pair of massive stars that were born together and "die" together as neutron stars before merging.
[2] The measured redshift is z=1.754.
[3] This era is analogous to the Universe's teenage years -- a lot is happening, everything is kind of messy, and galaxies are growing fast and haven't settled down into the maturity of their later years.

COVID-19 makes clear the need to address social determinants of health

An opportunity to emphasize equity, social determinants, and prevention in primary care
AMERICAN ACADEMY OF FAMILY PHYSICIANS

University of Michigan public health experts Julia Wolfson and Cindy Leung argue that the COVID-19 pandemic has made glaringly apparent the structural conditions that underlie inequities in our nation's health. Race and ethnicity, housing, income, occupation and chronic health conditions are all key factors that influence one's ability to safely weather highly infectious disease pandemics like COVID-19. Unlike the novel coronavirus strain, these social, economic and structural factors are not new. The authors argue, "An opportunity exists to use the unfolding crisis to advocate for structural changes to a system that has long perpetuated disparities." Wolfson and Leung draw together four articles in the July-August 2020 issue of the Annals of Family Medicine that emphasize social determinants of health and highlight the calls to action for primary care.

International conference on social determinants of health identified change needs

Improving Equity Through Primary Care: Proceedings of the 2019 Toronto International Conference on Quality in Primary Care
AMERICAN ACADEMY OF FAMILY PHYSICIANS
In November 2019, clinicians, health administrators, educators and researchers from around the world gathered in Toronto to discuss how to best address social determinants of health from a primary care perspective. Participants developed starting points for accessible and feasible actions to improve health equity in their own primary care setting. They emphasized strategies to incorporate community members, especially those with lived experiences of discrimination, in the health care design team. Additionally, they highlighted the need to address structural determinants of health, including racism, capitalism and colonialism.

LGBT-friendly medical practices improve STD/HIV screening rates for vulnerable populations

Transforming primary care for lesbian, gay, bisexual, and transgender people: a collaborative quality improvement initiative
AMERICAN ACADEMY OF FAMILY PHYSICIANS
This report--describing the first national quality improvement collaborative focused on providing culturally affirming care for LGBT people--finds that making primary care practices more LGBT-friendly and inclusive may improve STD and HIV screening rates among this vulnerable population. The goal of the Transforming LGBT Care program was to help highly motivated community health centers implement LGBT-affirming care by providing infrastructure for training, collaboration, knowledge sharing, leadership buy-in and practice change. Ten federally qualified health centers were selected to participate in the year-long program. Small care teams were formed at each site, and those teams received coaching, training and facilitation from the program's staff, much of which was conducted virtually. By the end of the program, estimated HIV screening of LGBT patients at eight of the reporting sites rose from 14.8 percent to 30.5 percent, with increases in STD screenings as well. Most participating centers had improved their electronic health record system to allow for sexual orientation and gender identity documentation, but very few reported improvements in documenting the sexual histories of LGBT patients. The authors of the program's quality improvement study note, "Ultimately, federally qualified health centers and other primary care organizations have an opportunity and a responsibility to provide equitable care to people of all sexual orientations and gender identities. Even small changes to health care practices may make a large difference for people burdened by health disparities and discrimination."

Experts' high-flying study reveals secrets of soaring birds

New research has revealed when it comes to flying the largest of birds don't rely on flapping to move around. Instead they make use of air currents to keep them airborne for hours at a time.
The Andean condor - the world's heaviest soaring bird which can weigh in at up to 15kg - actually flaps its wings for one per cent of its flight time.
The study is part of a collaboration between Swansea University's Professor Emily Shepard and Dr Sergio Lambertucci in Argentina, that uses high-tech flight-recorders on Andean condors. These log each and every wingbeat and twist and turn in flight as condors search for food.
The team wanted to find out more about how birds' flight efforts vary depending on environmental conditions. Their findings will help to improve understanding about large birds' capacity for soaring and the specific circumstances that make flight costly.
During the study, the researchers discovered that more than 75 per cent of the condors' flapping was associated with take-off.
However, once in the sky condors can sustain soaring for long periods in a wide range of wind and thermal conditions - one bird managed to clock up five hours without flapping, covering around 172 km or more than 100 miles.
The findings are revealed in a new paper Physical limits of flight performance in the heaviest soaring bird, which has just been published by Proceedings of the National Academy of Sciences.
Dr Hannah Williams, now at the Max Planck Institute for Animal Behaviour, said: "Watching birds from kites to eagles fly, you might wonder if they ever flap.
"This question is important, because by the time birds are as big as condors, theory tells us they are dependent on soaring to get around.
"Our results revealed the amount the birds flapped didn't change substantially with the weather.
"This suggests that decisions about when and where to land are crucial, as not only do condors need to be able to take off again, but unnecessary landings will add significantly to their overall flight costs."
Professor Shepard, who is part of Swansea Lab for Animal Movement, said as all the birds they studied were immature, it demonstrated that low investment in flight is possible even in the early years of a condor's life.
Closer examination showed the challenges the birds faced as they moved between weak thermals. The condors were seen to flap more as they reached the end of the glides between thermals when they were likely to be closer to the ground.
Dr Lambertucci explained: "This is a critical time as birds need to find rising air to avoid an unplanned landing. These risks are higher when moving between thermal updrafts.
"Thermals can behave like lava lamps, with bubbles of air rising intermittently from the ground when the air is warm enough. Birds may therefore arrive in the right place for a thermal, but at the wrong time."
"This is a nice example of where the behaviour of the birds can provide insight into the behaviour of the air."
