Teachers can use popular media to address anti-Asian bias, KU research shows

Critical race media literacy effective approach, schools should use to address difficult topics, scholars argue

UNIVERSITY OF KANSAS

Research News

 

LAWRENCE -- Recent incidents of racial discrimination and violence against Asians and Asian-Americans in the United States have prompted critical discussions about how to talk about such biases with younger age groups. New research from the University of Kansas shows using critical race media literacy, or examining how race and gender are addressed in popular culture, can be an effective way to discuss those topics and engage students.

KU researchers published a study in which they observed an American teacher using critical race media literacy to discuss racism and sexism in superhero movies in English as a foreign language classes in a South Korean high school. They argued that successful implementation can provide a model for discussing social topics in K-12 classrooms in countries like the United States.

Hyesun Cho"I think now, more than ever, it's important for us educators to teach our students how to contest prejudice and discrimination against certain racial groups," said Hyesun Cho, associate professor of curriculum & teaching in KU's School of Education & Human Sciences.

The recent mass shooting of several Asian-American women in Atlanta made headlines, but the topic can be difficult to discuss in schools.

"Teachers often are hesitant to discuss race and gender in the classroom because they are understandably concerned about sounding too political," said Peter Johnson, doctoral candidate in curriculum & teaching and study co-author. "I think that is one roadblock that we need to address, and this approach can help do that."

The study was published in the International Journal of Multicultural Education and presented at the Second Language Research Forum 2020 Conference hosted by Vanderbilt University.

Cho has led a study abroad program with KU students since 2015, traveling to South Korea to gain experience working in high schools while teaching English. The researchers observed classes where students explored issues of racism or sexism in popular culture on their own. Several groups of students shared examples in popular movies like "Black Panther" and "Dr. Strange" to appeal to their classmates. Students made presentations in English about how the wildly popular films addressed race both in positive ways, such as empowering African characters in "Black Panther," and in more negative ways, including a white actor portraying an Asian character in the 2016 film "Doctor Strange." The students were highly effective at discussing critical race theory and other complex topics, the authors wrote, and using media that students find compelling is a key way to give students a safe, comfortable way to discuss difficult topics.

"Do not underestimate our students' intelligence and higher thinking skills. That's the argument we're making here, even if they are working in a second or third language," Cho said. "Discussing critical race media literacy worked very well in Korean classrooms, despite misconceptions that often exist about these students' English proficiency and cultural background. If the teacher gets to know students and their interests and creates a safe space for them to express their thoughts about social issues, this approach can work in other teaching contexts."

Not only can using topics relevant to students' interests help encourage their participation, but it can help teachers connect with students. Educators are more effective when they get to know their students, their communities, families, backgrounds and experiences, Cho and Johnson wrote. The teacher in the study was born in Thailand, raised in the United States and speaks English as a first language. However, he faced discrimination when applying for jobs at South Korean schools, as it was assumed he was not a "true, American English speaker" because he was not white. Sharing such experiences can help expand discussions of power structures beyond media representations.

South Korea, like the United States, has an educational culture highly focused on testing and assessment. A common argument is that topics like racism and sexism can't or shouldn't be covered in school because they take time away from focusing on testing areas. However, the students displayed high levels of critical thinking, use of language, technological savvy and other educational skills in their presentations. That success suggests adaptability to other settings and levels of curriculum, Cho and Johnson wrote.

Cho said she hoped to return to South Korea to study other implementations of critical race media literacy in classrooms to gauge their effectiveness and to form new recommendations for teachers to address the topics in their own classrooms. Both Cho and Johnson also encourage prospective educators they are currently teaching to consider such methods to engage their future students and empower them to take ownership of their education.

"We try to frame it for our future teachers so that they understand they are able to have a classroom where students feel comfortable to ask the questions they have on their minds," Johnson said. "It can be tough to strike a good balance, but this shows they can use media such as films students are interested in to get them to think about deeper issues."

While it can be difficult to discuss to racism, sexism or the recent violence against Asians and Asian-Americans in a classroom setting, the use of critical race media literacy works, the researchers said.

"This is a new imperative for survival in the current, racially contested world. Especially given the anti-Asian-American violence we have seen in the U.S., it is everyone's responsibility to address it," Cho said. "Students want to be heard, and this study shows it's not an impossible task to discuss these social issues and can be done in a way that uses content relevant and readily accessible to students throughout K-12 education."

THE SHOCKING TRUTH!

Degrees of happiness? Formal education does not lead to greater job satisfaction, study shows

UNIVERSITY OF NOTRE DAME

Research News

 

Education is considered one of the most critical personal capital investments. But formal educational attainment doesn't necessarily pay off in job satisfaction, according to new research from the University of Notre Dame.

In fact, there is almost no relationship between the two, according to "Does Educational Attainment Promote Job Satisfaction? The Bittersweet Trade-offs Between Job Resources, Demands and Stress," forthcoming in the Journal of Applied Psychology from Brittany Solomon (Hall), assistant professor of management, and Dean Shepherd, the Ray and Milann Siegfried Professor of Entrepreneurship, both at Notre Dame's Mendoza College of Business, along with Boris Nikolaev from Baylor University.

"Our study shows people who have invested in formal education do not tend to be more satisfied in their jobs," Solomon said. "We found that better-educated individuals do enjoy greater job-related resources including income, job autonomy and variety. But they also endure longer work hours and increased job pressure, intensity and urgency. On average, these demands are associated with increased stress and decreased job satisfaction, largely offsetting the positive gains associated with greater resources."

In supplemental analyses, the team found that women were more likely to experience an increased negative association between education and job satisfaction, and self-employed individuals experienced a reduced negative association.

"Women still face workplace adversity that can undermine the positive returns on their educational investment," Solomon said. "This dynamic is particularly important given the reversal of the gender gap in education, with more women completing higher education than men. We explored the notion that the education-job satisfaction link is negative and stronger for women and discovered that, compared to their highly educated male counterparts, highly educated women experience more stress at work and lower job satisfaction."

Relative to traditional occupations, self-employment offers considerable flexibility to organize one's work schedule, choose the work content and decide how to respond to job demands.

"We found that, compared to their wage-employed counterparts, those in self-employment seem to be more insulated from the adverse effects of education on job stress and satisfaction," Solomon said. "We believe illuminating this boundary condition is notable for the educated and organizations that value and want to retain their educated employees."

The researchers do not suggest avoiding higher education in an effort to achieve higher job satisfaction, but recommend a realistic calculation of trade-offs between "good" and "bad" working conditions and the associated stress and job satisfaction.

"Balancing those conditions that lead to both stress and job satisfaction may help workers recalibrate their values and ultimately make decisions that suit their priorities," Solomon said. "Leaders may also consider better ways to manage the greater demands encountered by their highly educated employees so that exploiting an organization's greatest human capital does not backfire. For example, by removing incentives for employees to take on excessive work hours, organizations can avoid inadvertently pressuring employees to incur stress that undermines job satisfaction.

"Many people pursue higher education to get a better job on paper, not realizing that this 'better job' isn't actually better due to the unanticipated effects of demands and stress over time," Solomon said. "It's good for people to be realistic about the career paths they pursue and what they ultimately value."

Remote monitoring could boost the use of nature-based solutions to safeguard against natural hazards

UNIVERSITY OF SURREY

Research News

 

Remote monitoring using airborne devices such as drones or satellites could revolutionise the effectiveness of nature-based solutions (NBS) that protect communities from devastating natural hazards such as floods, storms and landslides, say climate change experts from the University of Surrey.

Grey structural measures (a collective term for engineering projects that use concrete and steel) like floodgates, dams, dikes and sea walls are still the most common methods to guard against natural hazards. However, these 'grey measures' are expensive and lack the long-term flexibility and sustainability needed to help communities manage their growing population and address the planet's ongoing struggle against urbanisation and climate change. While NBS are cost-effective, their usability and reproducibility are often hindered by the lack of standard monitoring methods, tools and indicators.

In a comprehensive study published in the Earth-Science Reviews journal, researchers from Surrey's Global Centre for Clean Air Research (GCARE) collaborated with experts from across Europe* to analyse monitoring methods that measure the effectiveness of NBS - such as wetlands, forest restoration projects and installation of green walls.

In the paper, the team found that while there is a need for combining ground and remote monitoring methods for holistic assessment, the advances in remote monitoring techniques present a significant source of hope for routinely, continually and accurately measuring the effectiveness of NBS and quelling skepticism around choosing NBS over grey-engineered options. Remote monitoring offers the ability to cover large geographical areas, and high-resolution imagery could change the way farmers, scientists, hazard managers and other decision-makers view NBS usage and applicability.

However, the study also warns that the lack of globally accepted standards to gauge an NBS success hinders their progress and use and needs to be urgently addressed.

Professor Prashant Kumar, Associate Dean (International) and the Director of the GCARE at the University of Surrey, said: "Unfortunately we do expect a significant uptick in natural hazards, thanks to climate change. Therefore, our decisions on how we protect ourselves are crucial, and nature-based solutions have the advantages of being flexible and not adding to the damage caused to our environment.

"I hope that this review begins an urgent discussion on how we can move forward as a scientific community and start to develop an accepted framework for measuring the effectiveness of nature-based solutions."

Infants' language skills more advanced than first words suggest

Babies can recognize combinations of words even before they have uttered their first word, a study suggests, challenging ideas of how children learn language

UNIVERSITY OF EDINBURGH

Research News 

Babies can recognise combinations of words even before they have uttered their first word, a study suggests, challenging ideas of how children learn language.

Assessments in 11-12 month-olds show that infants at the cusp of talking are already processing multiword phrases such as 'clap your hands'.

Researchers say the study is the first to provide evidence that young children can pick up and understand multiword sequences before they can talk or begin producing such combinations themselves.

The findings suggest that babies learn individual words and more complex phrases at the same time, which challenges the perspective that they progress from single words to phrases and sentences, experts say.

It may also explain why adults who learn a new language in later life by focusing on individual words often do not achieve native-like proficiency.

Linguists at the University of Edinburgh assessed 36 infants' language learning behaviour in a series of attention tests using recorded adult speech.

They looked at how the babies responded to multiword combinations of three-word sequences used in parent-child conversations.

The researchers compared the infants' responses using a testing method called central fixation, which measures infants' looking behaviour in response to sounds.

They assessed if the babies could distinguish more frequently used three-word sequences such as 'clap your hands' from similar but less common phrases such as 'take your hands'.

On average, fixation times were longer for the frequently used phrases. This pattern was found in 23 of the 36 infants.

Researchers say this suggests babies who are still learning their first words are simultaneously learning word combinations.

This development happens months before parents hear their children's first attempts at sequences of words, experts say.

Dr Barbora Skarabela, of the School of Philosophy, Psychology and Languages Sciences, said: "Previous research has shown that young infants recognise many common words. But this is the first study that shows that infants extract and store more than just single words from everyday speech. This suggests that when children learn language, they build on linguistic units of varying sizes, including multiword sequences, and not just single words as we often assume. This may explain why adults learning a second language, who tend to rely on individual words, often fall short of reaching native-like proficiency in the way they string words together into phrases and sentences."

Doctors experiencing domestic abuse feel socially and professionally isolated

UNIVERSITY OF SOUTHAMPTON

Research News

 

Female doctors who suffer domestic abuse can feel unable to get help due to perceptions that it "should not happen to a doctor" and a judgemental culture in medical settings, a new study suggests.

Victim-survivors who work as doctors often do not feel able to talk about abuse confidentially and fear the consequences of reporting it.

Researchers from the University of Southampton interviewed twenty-one female doctors who had previously left an abusive relationship about their experience of domestic abuse, barriers they faced when seeking help, and the impact on their work. The findings have been published in the British Journal of General Practice.

Dr Emily Donovan, who led the study from the University of Southampton's Primary Care Research Centre said: "Domestic abuse is a huge problem for women from all walks of life but I was surprised to hear through conversations how prevalent it seemed to be in the medical profession. Despite this, very little has been written about doctors who are victims, all the research seems to focus on how doctors help other victims of domestic abuse. So I wanted to find out more about how it affected these women at work and their experiences of seeking support."

1. "It shouldn't happen to a doctor"

Several participants expressed embarrassment and felt that, as doctors, they "should have known better" and that they are "supposed to be intelligent, strong women who are not vulnerable." This could also lead them to question how they would be able to help their patients whilst feeling as though they could not look after themselves.

Despite the perceptions that it should not happen to them, many of the victim-survivors said that the nature of their job actually made them more vulnerable to persistent domestic abuse. Because they work hard every day to resolve problems for others, it was natural for this determination to 'keep going' to continue in their personal lives. For some participants, routinely dealing with difficult and demanding colleagues normalised the poor treatment that they experienced at home, causing them to persist with relationships even after they had become abusive.

2. Hard to disclose problems or seek help from fellow health professionals.

The study identified a number of barriers to disclosing and seeking help, the main concerns being confidentiality, for example having to speak to health professionals who they know personally or professionally.

Many participants said that not fitting the stereotype of a female suffering domestic abuse caused disbelief from health professionals from whom they sought help as a patient. Some victim-survivors felt that health or social care professionals were quick to shut the conversations down, whilst some were threatened with being reported to the General Medical Council (GMC).

Problems in disclosure were particularly prominent when the abusive partner was also a health professional, which often deterred the victim-survivor from reporting the abuse through fear that they would not be believed due to their partner's status.

3. A "judgemental" medical culture

A culture of presenteeism in medical settings and perception that weakness is not tolerated also made it difficult to get the time off needed to access domestic abuse services during working hours.

When victim-survivors were able to speak to health professionals who would listen and validate that they were experiencing domestic abuse, it made a huge difference. Peer support groups were also extremely valuable in helping them understand that they were not alone and inspiring them to take action.

Speaking about how the medical profession can support its workers, Dr Donovan said, "A designated confidential service for doctor victim-survivors would give them access to support without the risk of meeting their patients and colleagues.

"The medical profession also needs to change its culture so that its workers feel that they can talk to each other more and that they are being looked after as well as their patients."

 

Cardiorespiratory fitness improves grades at school

By confirming the link between children's cardiorespiratory fitness and their school results, researchers at the UNIGE underline the importance of physical education classes at school.

UNIVERSITÉ DE GENÈVE

Research News

 

Recent studies indicate a link between children's cardiorespiratory fitness and their school performance: the more athletic they are, the better their marks in the main subjects - French and mathematics. Similarly, cardiorespiratory fitness is known to benefit cognitive abilities, such as memory and attention. But what is the real influence of such fitness on school results? To answer this question, researchers at the University of Geneva (UNIGE), Switzerland tested pupils from eight Geneva schools. Their results, published in the journal Medicine & Science in Sport & Exercise, show that there is an indirect link with cardiorespiratory fitness influencing cognitive abilities, which in turn, influence school results.

Charles Hillman, a professor at Northeastern University in Boston and co-author of this study, has suggested in previous research that there is a link between children's cardiorespiratory fitness and their academic performance, as well as a beneficial effect of cardiorespiratory fitness on executive functions. "There are three main executive functions", explains Marc Yangüez, a researcher at the UNIGE's Faculty of Psychology and Educational Sciences (FPSE) and first author of the study. "The first is inhibition, i.e., our ability to inhibit intrusive or irrelevant behaviour or thoughts. The second is cognitive flexibility, which often called multitasking, and refers to our ability to flexibility move between tasks or responses based on task demands. Finally, the third is working memory, which is our ability to maintain information in our minds and manipulate it."

However, the link between fitness and academic skills does not seem obvious at first sight. This is why researchers at the UNIGE wanted to analyze it and observe how one influences the other and whether a specific cognitive process plays a predominant role.

Testing the physical and cognitive abilities of Geneva students

The Geneva investigators teamed up with eight schools in the canton of Geneva to conduct cognitive and physical tests on 193 pupils aged 8 to 12. First of all, children took a physical test known as the "shuttle run test": the children had to run back and forth between two lines 20 meters apart at an increasingly fast pace. "Combined with height, weight, age and sex, this test allows us to assess the child's cardiovascular fitness", says Marc Yangüez. "Following this, we used nine tasks that allow us to assess children's abilities in the three main executive functions - inhibition, cognitive flexibility and working memory - and we measured different indicators such as the precision and speed of their responses", explains Julien Chanal, researcher at the FPSE of the UNIGE. For example, one of the tests of inhibition presents students with images of fish swimming. The central fish can either swim in the same direction as the others or in the opposite direction. The students have to indicate as quickly and accurately as possible the direction in which the central fish is swimming when they are only shown the picture for 200 milliseconds. To measure cognitive flexibility, the students took three tests as well, one of the tests asked the students to connect in ascending order numbers and letters (1-A-2-B-3-C, etc.). In one of the working memory tests, the students had to memorize a sequence of numbers, such as 2 6 4 9 7, and then repeat them in the reverse order. In addition, at the end of the year, the teachers, with the parents' consent, transmitted the students' marks for the three terms of the year in mathematics, French 1 (comprehension and expression of text) and French 2 (grammar, spelling and vocabulary).

An indirect link between cardiorespiratory fitness and school results

By combining the data obtained, the psychologists found that there was a link between better cardiorespiratory fitness and higher marks in mathematics and French 2. "French 1 is probably less directly concerned, because the evaluation of the text and the writing depend more on subjective factors, which is less the case for mathematics or grammar, for which there is little subjectivity in the right or wrong answers", explains Marc Yangüez. In addition to the existence of a link between cardiorespiratory fitness and school results, the data obtained also confirm a link between cardiorespiratory fitness and executive functions. But does good cardiorespiratory fitness affect academic performance directly or indirectly through executive functions?

"By decomposing these effects via a statistical mediation model, we established that the link between cardiorespiratory fitness and academic performance was indirect. In fact, physical fitness is related to better executive functions, and it is indeed executive functions that influences school performance, more specifically cognitive flexibility", emphasizes Julien Chanal.

Important results for the planning of physical education in schools

The results of this study are important for the organization of school planning. "By demonstrating the link between physical capacities, such as cardiorespiratory capacity, cognitive abilities and grades, it underlines the importance of not reducing physical activity (and in particular physical education hours) in favour of other subjects, as this could ultimately have a negative impact on the development of the child as a whole", says Marc Yangüez. This study also challenges the idea of forcing children to study more and spend more time at their desks in order to succeed at school, depriving them of physical exercise. Finally, and all the more so in times of a pandemic, the Geneva psychologists stress the importance of not depriving children of movement, which would be detrimental to both their physical health and their cognitive health. "We would now like to carry out an intervention study into schools in different regions of Switzerland, in order to demonstrate on a large scale that when children's weekly physical activity increases, it has a positive impact on the development of executive functions, leading to a significant improvement in school results", concludes Julien Chanal.

A team of researchers from Graz University of Technology, Know-Center GmbH, Johannes Kepler University Linz, University of Innsbruck, Austria and University of Utrecht, the Netherlands, compared how accurate algorithm-generated music recommendations were for mainstream and non-mainstream music listeners. They used a dataset containing the listening histories of 4,148 users of the music streaming platform Last.fm who either listened to mostly non-mainstream music or mostly mainstream music (2,074 users in each group). Based on the artists music users' listened to most frequently, the authors used a computational model to predict how likely music users were to like the music recommended to them by four common music recommendation algorithms. They found that listeners of mainstream music appeared to receive more accurate music recommendations than listeners of non-mainstream music.

Algorithm to classify music listeners

The authors then used an algorithm to categorise the non-mainstream music listeners in their sample based on the features of the music they most frequently listened to. These groups were: listeners of music genres containing only acoustic instruments such as folk, listeners of high-energy music such as hard rock and hip-hop, listeners of music with acoustic instruments and no vocals such as ambient, and listeners of high-energy music with no vocals such as electronica. The authors compared the listening histories of each group and identified which users were the most likely to listen to music outside of their preferred genres and the diversity of music genres listened to within each group.

Those who mostly listened to music such as ambient were found to be most likely to also listen to music preferred by hard rock, folk or electronica listeners. Those who mostly listened to high-energy music were least likely to also listen to music preferred by folk, electronica or ambient listeners, but they listened to the widest variety of genres, for example hard rock, punk, singer/songwriter and hip-hop,

The authors then used users' listening histories and a computational model to predict how likely the different groups of non-mainstream music listeners were to like the music recommendations generated by the four common music recommendation algorithms. They found that those who listened to mostly high-energy music appeared to receive the least accurate music recommendations and those who mostly listened to music such as ambient appeared to receive the most accurate recommendations.

Biased music recommendation algorithms

Elisabeth Lex, the corresponding author, said: "As increasing amounts of music have become available via music streaming services, music recommendation systems have become essential to helping users search, sort and filter extensive music collections. Our findings suggest that many state-of-the-art music recommendation techniques may not provide quality recommendations for non-mainstream music listeners. This could be because music recommendation algorithms are biased towards more popular music, resulting in non-mainstream music being less likely to be recommended by algorithms."

"Further," added Elisabeth Lex, "our results indicate that the music preferences of those who mostly listen to music such as ambient can be more easily predicted by music recommendation algorithms than the preferences of those who listen to music such as hard rock and hip-hop. This means that they may receive better music recommendations.

The authors suggest that their findings could inform the creation of music recommendation systems that provide more accurate recommendations to non-mainstream music listeners. However, they caution that as their analyses are based on a sample of Last.fm users their findings may not be representative of all Last.fm users or users of other music streaming platforms.

This research area is anchored in the Field of Expertise "Information, Communication & Computing", one of five strategic foci of TU Graz.

Smokers motivated to 'quit for COVID' to ease burden on health system

GEORGE INSTITUTE FOR GLOBAL HEALTH

Research News

 

An international survey that included 600 smokers in the UK has found that cessation messaging focused on easing the burden on our health system is most effective in encouraging people to quit.

The research, which was conducted in April-May 2020, randomly assigned participants to view one of four quit smoking messages, two of which explicitly referenced health implications and COVID-19, one referred more vaguely to risk of chest infection, and one highlighted financial motivations for quitting.

"We wanted to explore the effectiveness of smoking cessation messaging at a time when health systems the world over are beleaguered, and all our lives have had to pivot into pandemic-response mode," said ProfessSimone Pettigrew (Head of Food Policy at The George Institute for Global Health), who led the research.

or All four messages were effective in terms of increasing participants' intentions to quit within a fortnight and prompting them to seek additional information around COVID-19 risk, with the two messages that specifically mentioned COVID-19 the most impactful:

MESSAGE A. By quitting now, you can reduce your chances of experiencing complications from the coronavirus if you become infected. This will help our overstretched health services to cope with the huge increase in patients.

MESSAGE B. Quit now - it's never too late. Smoking damages your lungs so they don't work as well. This means smokers are more likely to have severe complications if infected by the coronavirus.

Message A (referring to both personal consequences and to the impact on the functioning of the health system) landed best with participants, 34% of whom reported intention to quit and 44% sought additional information about the risks of COVID for smokers.

The latest figures from NHS England reflect a heavily loaded health system, with adult critical care bed occupancy at 67% across England. Public Health England is advising smokers to quit to improve their chances of avoiding infection and surviving COVID-19 if contracted.

This research can help tailor such communication for optimal impact, prioritising messages that reference COVID-related health risk.

Pandemic stress, boredom caused some PA residents to increase cigarette use

PENN STATE

Research News

 

HERSHEY, Pa. -- Stress, increased free time and feelings of boredom may have contributed to an increase in the number of cigarettes smoked per day during the early months of the COVID-19 pandemic by nearly a third of surveyed Pennsylvania smokers. Penn State College of Medicine researchers said understanding risk factors and developing new strategies for smoking cessation and harm reduction may help public health officials address concerning trends in tobacco use that may have developed as a result of the pandemic.

Jessica Yingst, assistant professor of public health sciences and Penn State Cancer Institute researcher, said smokers who increased the number of cigarettes they smoked per day could be at greater risk of dependence and have a more difficult time quitting.

Researchers asked 291 smokers about their tobacco use patterns before and during the early months of the pandemic including how frequently they used tobacco products, reasons why their use patterns changed and whether they attempted to quit. Nearly a third of smokers reporting increased use due to stress, increased free time and boredom. One participant stated, "Working at home allows me to smoke at will rather than being in a smoke-free environment for 8 hours per day." In contrast, 10% of participants decreased their tobacco use and attributed that to schedule changes, being around non-smokers such as children, and health reasons.

Nearly a quarter of participants reported attempting to quit smoking during the pandemic. A third of those who attempted to quit conveyed that they did so to reduce their risk of poor outcomes should they become infected with COVID-19. One participant stated, "I quit as soon as I came down with a fever and cough. Clearly, I am aware of how detrimental smoking is to my health; however, I did not consider how it could make me more vulnerable to COVID-19 and its effects. I was terrified and quit immediately." Ultimately, seven people were successful in quitting all tobacco use.

The research team also asked the participants about their perceptions of health risks during the pandemic. More than two-thirds of participants believed their risk of contracting COVID-19 was the same as non-tobacco users. However, more than half of those surveyed thought they were at higher risk to suffer serious complications from COVID-19. The results were published in the International Journal of Environmental Research and Public Health.

"Knowing the reasons for increased tobacco use and the motivations of those who successfully quit smoking can help us identify how to better address cessation efforts during the pandemic," Yingst said. "New methods like telemedicine and increasing public health messaging could encourage people to stop smoking in the absence of public support groups or other in-person interventions."

Fasting acts as diet catalyst

Research News

 

One in four Germans suffers from metabolic syndrome. Several of four diseases of affluence occur at the same time in this 'deadly quartet': obesity, high blood pressure, lipid metabolism disorder and diabetes mellitus. Each of these is a risk factor for severe cardiovascular conditions, such as heart attack and stroke. Treatment aims to help patients lose weight and normalise their lipid and carbohydrate metabolism and blood pressure. In addition to exercise, doctors prescribe a low-calorie and healthy diet. Medication is often also required. However, it is not fully clear what effects nutrition has on the microbiome, immune system and health.

A research group led by Dr Sofia Forslund and Professor Dominik N. Müller from the Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC) and the Experimental and Clinical Research Center (ECRC) has now examined the effect a change of diet has on people with metabolic syndrome. The ECRC is jointly run by the MDC and Charité Universitätsmedizin Berlin. "Switching to a healthy diet has a positive effect on blood pressure," says Andras Maifeld, summarising the results. "If the diet is preceded by a fast, this effect is intensified." Maifeld is the first author of the paper, which was recently published in the journal "Nature Communications".

Broccoli over roast beef

Dr Andreas Michalsen, Senior Consultant of the Naturopathy Department at Immanuel Hospital Berlin and Endowed Chair of Clinical Naturopathy at the Institute for Social Medicine, Epidemiology and Health Economics at Charité - Universitätsmedizin Berlin, and Professor Gustav J. Dobos, Chair of Naturopathy and Integrative Medicine at the University of Duisburg-Essen, recruited 71 volunteers with metabolic syndrome and raised systolic blood pressure. The researchers divided them into two groups at random.

Both groups followed the DASH (Dietary Approach to Stop Hypertension) diet for three months, which is designed to combat high blood pressure. This Mediterranean-style diet includes lots of fruit and vegetables, wholemeal products, nuts and pulses, fish and lean white meat. One of the two groups did not consume any solid food at all for five days before starting the DASH diet.

On the basis of immunophenotyping, the scientists observed how the immune cells of the volunteers changed when they altered their diet. "The innate immune system remains stable during the fast, whereas the adaptive immune system shuts down," explains Maifeld. During this process, the number of proinflammatory T cells drops, while regulatory T cells multiply.

A Mediterranean diet is good, but to also fast is better

The researchers used stool samples to examine the effects of the fast on the gut microbiome. Gut bacteria work in close contact with the immune system. Some strains of bacteria metabolise dietary fibre into anti-inflammatory short-chain fatty acids that benefit the immune system. The composition of the gut bacteria ecosystem changes drastically during fasting. Health-promoting bacteria that help to reduce blood pressure multiply. Some of these changes remain even after resumption of food intake. The following is particularly noteworthy: "Body mass index, blood pressure and the need for antihypertensive medication remained lower in the long term among volunteers who started the healthy diet with a five-day fast," explains Dominik Müller. Blood pressure normally shoots back up again when even one antihypertensive tablet is forgotten.

Blood pressure remains lower in the long term - even three months after fasting

Together with scientists from the Helmholtz Centre for Infection Research and McGill University, Montreal, Canada, Forslund's working group conducted a statistical evaluation of these results using artificial intelligence to ensure that this positive effect was actually attributable to the fast and not to the medication that the volunteers were taking. They used methods from a previous study in which they had examined the influence of antihypertensive medication on the microbiome. "We were able to isolate the influence of the medication and observe that whether someone responds well to a change of diet or not depends on the individual immune response and the gut microbiome," says Forslund.

If a high-fibre, low-fat diet fails to deliver results, it is possible that there are insufficient gut bacteria in the gut microbiome that metabolise fibre into protective fatty acids. "Those who have this problem often feel that it is not worth the effort and go back to their old habits," explains the scientist. It is therefore a good idea to combine a diet with a fast. "Fasting acts as a catalyst for protective microorganisms in the gut. Health clearly improves very quickly and patients can cut back on their medication or even often stop taking tablets altogether." This could motivate them to stick to a healthy lifestyle in the long term.

The Max Delbrück Center for Molecular Medicine (MDC)

The Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC) was founded in Berlin in 1992. It is named for the German-American physicist Max Delbrück, who was awarded the 1969 Nobel Prize in Physiology and Medicine. The MDC's mission is to study molecular mechanisms in order to understand the origins of disease and thus be able to diagnose, prevent and fight it better and more effectively. In these efforts the MDC cooperates with the Charité - Universitätsmedizin Berlin and the Berlin Institute of Health (BIH) as well as with national partners such as the German Center for Cardiovascular Research and numerous international research institutions. More than 1,600 staff and guests from nearly 60 countries work at the MDC, just under 1,300 of them in scientific research. The MDC is funded by the German Federal Ministry of Education and Research (90 percent) and the State of Berlin (10 percent), and is a member of the Helmholtz Association of German Research Centers. http://www.mdc-berlin.de

WASHINGTON, March 30, 2021 -- Emerging technologies can screen for cervical cancer better than Pap smears and, if widely used, could save lives both in developing nations and parts of countries, like the United States, where access to health care may be limited.

In Biophysics Reviews, by AIP Publishing, scientists at Massachusetts General Hospital write advances in nanotechnology and computer learning are among the technologies helping develop HPV screening that take the guesswork out of the precancer tests. That could mean better screening in places that lack highly trained doctors and advanced laboratories.

Cervical cancer is the world's fourth-most common cancer, with more than 500,000 cases diagnosed every year. Almost all cases of cervical cancer are caused by HPV, or human papillomavirus. Detecting precancer changes in the body gives doctors a chance to cure what could otherwise become a deadly cancer.

Pap smears, which were introduced in the 1940s, are subjective and not always reliable. The tests, which can detect about 80% of developing cervical cancer if given regularly, require high-quality laboratories, properly trained clinical doctors, and repeated screenings. These test conditions are not widely available in many countries or even in low-income and remote parts of wealthier nations.

"The Pap smear has done wonders in terms of reducing mortality from a cancer that is very treatable when caught early and almost invariably fatal when it is caught late," said author Cesar Castro, an oncologist at Massachusetts General Hospital and associate professor at Harvard Medical School. "And it is not even a great test. Part of its imperfection is that there is subjectivity to it. The trained eye is the limiting step in the process. The untrained eye, or relatively untrained eye, can miss cancers."

The subjectivity of the test has led to a much higher death rate from cervical cancer in lower-income countries. The authors highlight a list of existing and emerging technologies that can be used to close the testing gap in those areas. They range from existing DNA testing and other Pap smear alternatives to next-generation technologies that use recent advances in nanotechnology and artificial intelligence.

One technique involves screening with tiny beads made of biological material that form a diamond shape when they contact HPV. Those shapes can be detected with powerful microscopes. When those microscopes are not available, a mobile phone app, built through machine learning, can be used to read them.

"Similar to COVID-19 testing, we have great technology in places like the United States that does not work well enough in other countries," said author Hyungsoon Im, a biomedical engineer at Massachusetts General Hospital and assistant professor at Harvard Medical School. "This is why there is great motivation to find next-generation, affordable technology to address this problem."
