WHAT During recent large-scale disasters, including the COVID-19 pandemic and major hurricanes, many hospitals and health care systems have activated their Hospital Incident Command System (HICS) to clarify roles and responsibilities and offer a clear organizational structure during a crisis. While forms of these systems have existed since the 1980s, one key element has been missing from HICS national guidelines: a focus on equity.

In a new editorial published in AJPH, Clark and Goralnick, both from the Brigham, and their co-author Richard Serino, NREMT-P, from the Harvard T.H. Chan School of Public Health, make the case for why a structural change is needed in the national HICS guidelines to ensure inclusion of an Equity Officer and subject matter experts in health care equity.

"The absence of equity as an emergency management principle in responses to COVID-19 has resulted in a slow and incomplete hospital response to the disproportionate mortality and morbidity in several historically marginalized populations," the authors write. "Defining an Equity Officer as a mandatory, core member of the command and general staff is a first step in mitigating inequities."

The authors describe the experience at the Brigham, where a diversity, equity and community health response team was established during the COVID-19 pandemic. Results from an after-action review helped identify strengths and weaknesses of the Brigham's HICS response.

"Many of those involved in the process acknowledged that we are at the beginning and have much work to do to ensure that equity is a core function of our response during the COVID pandemic and in future disasters," the authors write. "On the basis of our observations, we recommend a structural change to the national HICS guidelines: including an Equity Officer and embedded health equity specialists within each section."

Gender inequality study shows women under-represented on marketing academic journal boards

Research identifies structural systemic and institutional biases that perpetuate inequality for female academics

UNIVERSITY OF BATH

Research News

 

Women are significantly underrepresented in the editorial boards of marketing academic journals, and awards and recognition favour men, new research from the University of Bath School of Management has found.

In their study 'It's hard to be what you can't see - gender representation in marketing's academic journals', Professor Andrea Prothero of Business and Society at University College Dublin and co-researcher Professor Pierre McDonagh examined gender representation in 20 marketing academic journals through three areas - the gender composition of editorial boards, special issue celebrations and the awards process.

The research found that since 2017 the number of women in editorial board roles had grown by 4.5% and that the number of female editors-in-chief had risen to 39 percent from 18 percent over the same period. But men still held 68% of all editorial board roles and the discrepancy was even greater at the advisory board level.

"The results are stark, disappointing and somewhat shocking. I think many people might expect both marketing and academia to be progressive areas but in 2021 it is simply not acceptable for example, that 88% of advisory board members within our journals are men, or that some journals in our field have never had a female editor-in-chief," McDonagh said.

Prothero said she and McDonagh were moved to study this issue as they believed many scholars were not aware of the scale of the gender discrimination problem in marketing academic journals or of the particular challenges around awards and celebrations of academic achievement.

"Our research also highlighted how journal celebrations also favour men. Special issues for example include reflections from previous editors (who are mostly men), and invited commentaries (who are mostly men). And, where journals and/or their related associations celebrate outstanding research through awards processes, those awards which are named after leading figures in the field are all named after men!" she said.

McDonagh said he and Prothero were not arguing that women are deliberately excluded from awards and recognition, but that structural, systemic and institutional biases meant male colleagues were privileged over women.

"And this of course, also means that injustice and inequality for female academics are perpetuated. Our goal is to get scholars in the marketing academy to think differently about things that are hidden in plain sight. We also want them to join us in asking for meaningful change with respect to existing gender discrimination in the marketing journals," he said.

McDonagh said publishing houses and editors should take four steps towards tackling gender representation issues.

Firstly, build diversity into existing journal review boards, and second, introduce a quota system to ensure diversity of people across advisory boards, manuscript review boards, and in roles such as associate editors, co-editors, and editors-in-chief. Publishing houses in particular, have been discussing more inclusive and diverse editorial boards across academia, but Prothero said it was important to move beyond talk and implement new policies. And, while this study focused on gender representation, other dimensions such as race were equally as important.

"As a third step, we should ask awkward questions of the leaders in our field - why do the majority of named awards in our field honour white men? We request awards which also honour the leading people of colour and females in our field, he said.

Finally, Prothero and McDonagh urged editors-in-chief to celebrate those less visible to others.

"We have female role models for younger scholars to inspire them to greatness, but they are not celebrated or included either in editorial boards or in special issue celebrations to the same extent as men. Let's rectify this. Quite simply the current status quo is an injustice - not everyone is a white male academic, so why do they dominate everything?" he asked.

Fewer breast cancer cases between screening rounds with 3D-mammography

LUND UNIVERSITY

Research News

 

3D-mammography reduces the number of breast cancer cases diagnosed in the period between routine screenings, when compared with traditional mammography, according to a large study from Lund University in Sweden. The results are published in the journal Radiology.

"Our results indicate that 3D-mammography, or digital breast tomosynthesis, possibly detects cancers that would otherwise have been diagnosed later at a more advanced stage", says Kristin Johnson, doctoral student at Lund University and radiology resident at Skåne University Hospital.

A large prospective screening study conducted at Skåne University Hospital in Malmö (Malmö Breast Tomosynthesis Screening Trial) between 2010 and 2015 included almost 15,000 women who received both 3D-mammography and traditional mammography. In 2018, the researchers published results from the trial showing that 3D-mammography detects just over 30 percent more cases of breast cancer compared to traditional mammography.

This time, the researchers compared cancers detected in between screenings, so called interval cancers. The women who received 3D-mammography were matched by age and screening date with women in a control group who were screened using regular mammography. A total of 13,369 women were included in the study and 26,738 women in the control population.

The number of interval cancer cases can be used to assess a screening method's effectiveness in detecting cancer and potential to reduce breast cancer mortality in the long run, and is one of the most important outcome measures to take into account in discussions about possibly switching to 3D-mammography as a screening method. The researchers also compared the types of breast cancer involved as well as the extent of the spread of cancer in the patients.

"Among the study participants who received 3D-mammography, we found that it was less likely, 40 percent lower odds, to get interval cancer compared to the control group that was screened with regular mammography. Interval cancer cases generally have a relatively aggressive biological profile with faster growing tumors than in screening-detected breast cancer. However, the study did not show any major differences between the groups regarding the biological profile, says Kristin Johnson.

Kristin Johnson clarifies that the women who were screened with both 3D-mammography and 2D-mammography thus received two radiological assessments, in contrast to the control group. This may have had some effect on the fewer number of cases of interval cancer in the study group.

Several European studies have shown that 3D-mammography detects more cases of breast cancer, although the scientific basis for using 3D-mammography in screening is considered weak due to lack of information on effects on interval cancer rates. Therefore, today's overall European guidelines are still vague. In addition, the guidelines for screening programs differ between countries within as well as outside Europe.

The researchers believe that their results, which so far are the only ones published that show a reduced interval cancer rate, further support that 3D-mammography can supplement or replace mammography in screening. In the long run, they can also help strengthen the European recommendations.

"Screening with 3D-mammography shows potential in reducing interval cancers. However, we need to see more studies pointing in the same direction", concludes Kristin Johnson.

Digital twin can protect physical systems and train new users

CHINESE ASSOCIATION OF AUTOMATION

Research News

 

It is more complicated than copy and paste, but digital twins could be way of future manufacturing according to researchers from the University of Kentucky. They developed a virtual environment based on human-robot interactions that can mirror the physical set up of a welder and their project. Called a digital twin, the prototype has implications for evolving manufacturing systems and training novice welders. They published their work in the IEEE/CAA Journal of Automatica Sinica (Volume 8, Issue 2, February 2021).

"This human-robot interaction working style helps to enhance the human users' operational productivity and comfort; while data-driven welder behavior analysis benefits further novice welder training," said paper author YuMing Zhang, James R. Boyd Professor in electrical engineering at the University of Kentucky.

The researchers had a human demonstrate welder operations using a manual welding torch and a motion tracker. Their movements are transmitted to a machine that is actually welding. Sensors in the physical welding environment feedback data to the human. The physical environment, and incoming data, is accessible via an augmented virtual reality in which the human can make adjustments accordingly.

"In current developed digital twins, humans are the observers of the physical systems --information flow is one way," Zhang said. "For processes where intelligence from humans is needed, like precise welding, human-robot interaction needs to be integrated with the digital twins such that the humans' operative ability can be enhanced and the roles they play transmit from observers to dominators."

The researchers also tracked the behavior of six welders with different experience levels in the digital twin system. All welders were able to complete the same welding task, to varying levels of satisfaction. Analysis revealed the distinct patterns in the skilled and unskilled welders' operating behaviors and, ultimately, their work.

"The successful pattern recognition in skilled welder operations should help accelerate novice welder training," Zhang said.

The digital twin environment could, for example, provide a safe space for novice welders to practice techniques without the risk of dangerous or costly damages, as the system could be trained to recognize potentially harmful patterns and shut down.

"In future work, we plan to investigate efficient novice welder training based on this developed human-robot interactive welding with the recognized patterns from skilled welders and also upgrade the system to support multi-robot collaboration such that some more complex welding operations can be completed by this system," Zhang said. "As such, the system applicability can be increased greatly."

Estimating costs of uterine transplantation

UNIVERSITY OF GOTHENBURG

Sweden's acclaimed research on uterine transplants has taken a new step forward: into the field of health economics. Now, for the first time, there is a scientifically based estimate of how much implementing the treatment costs.

The current research is based on the nine uterine transplants from living donors carried out in 2013, under the leadership of Mats Brännström, Professor of Obstetrics and Gynecology at Sahlgrenska Academy, University of Gothenburg, and Chief Physician at Sahlgrenska University Hospital.

The transplants were performed within the scope of the world's first systematic, scientifically based study in the field. After the first birth in Gothenburg in 2014, there were a further seven births before a woman outside Sweden had a baby after a uterine transplant.

Now that the survey of costs is complete, the results have been reported with certain reservations. First, the number of cases studied is restricted to nine; second, the treatment has taken place as part of a research project, subject to the requirements this has entailed. Nonetheless, the study represents an initial indication of costs.

The researchers arrived at a total average sum per transplant, now reported in the journal Human Reproduction, of EUR 74,564 in current monetary value. This figure comprises costs relating to the recipient and donor alike.

The total includes, first, screening examinations and treatments, such as in vitro fertilization (IVF), in the year preceding the transplant; second, the actual operations on the donor and recipient; and third, costs in the two months after the transplant, including sick leave.

Sick leave (25.7%) was the single largest item in the cost calculation. The other categories were postoperative inpatient care (17.8%), surgery (17.1%), preoperative examinations (15.7%), anesthesia (9.7%), medication (7.8%), postoperative testing (4.0%), and readmission to hospital (2.2%).

The total is described as relatively high, due partly to the extensive scientific requirements. In a future clinical setting, the researchers say, aggregate transplant costs would likely be lower.

Thomas Davidson, Associate Professor in the area of Health Economics and Health Technology Assessment at Linköping University, and first author of the study, puts the matter in perspective.

"In terms of priorities, this study is important because it contributes key data for deciding whether to offer uterine transplants within publicly funded health care. A cost estimate is the starting point for upcoming assessment of whether the intervention is cost-effective."

Cost-effectiveness is usually measured in terms of cost per quality-adjusted life year (QALY) gained -- a yardstick that combines economic aspects with longevity and quality of life.

"In assessing cost-effectiveness, we have to relate both costs and effects, preferably measured in QALYs, to those of alternative treatments," Davidson says.

Lars Sandman -- Professor of Health Care Ethics, head of the Centre for Priority Setting in Health Care at Linköping University, and the study's co-author -- adds his comments.

"There are still essential issues we want to keep investigating. One is how we should regard the effects of a uterine transplant. Should the QALY gain generated include only the benefit to the mother of getting pregnant, giving birth and being the child's parent? Or should the benefit of a child being born and living on for a number of years, adding QALYs, be included as well? It makes a big difference in terms of the cost-effectiveness of the intervention, which is an important factor in the priority-setting context."

Professor Mats Brännström, corresponding author, sums up.

"All the costs of investigation, staff, and hospital care were funded through research grants. The grand total is close to what we'd calculated, and comparable to the current cost of kidney transplantation from a living donor. In all probability, future uterine transplantation will be more cost-effective thanks to the robot-assisted surgical technique we've developed, which means shorter hospital stays and patients returning to work sooner."

A novel way to pinpoint and illuminate bone damage promises to make X-rays more efficient at diagnosing bone and other injuries, Flinders University researchers say.

The new technique, looking at potential biomedical applications of an ancient inorganic salt-based aggregation induced emission (AIE) radio-luminescence material, could open new frontiers in medicine including X-ray dosimetry, bioimaging and advanced applications such as optogenetics, says Professor Youhong Tang, from Flinders University's College of Science and Engineering.

The review article, published by Professor Tang, postdoctoral student Dr Javad Tavokoli, colleagues in Hong Kong and Australian technology company Micro-X and, examined the potential of the AIEgen luminogens (AIEgens) in deep tissue imaging. The study used X-ray testing provided by Adelaide-based Micro-X.

"We were able to use Micro-X advanced X-ray machines at the Tonsley Innovation District to show the benefits of this AIEgen system which can be excited by X-ray (as the radioluminescence emitter) and UV light (as the photoluminescence emitter) compared to current AIEgens which mostly only act as the photoluminescence emitter," he says.

"The study highlighted the disadvantages of autofluorescence, poor signal-to-noise radio, and poor tissue penetration depth of traditional photoluminescence emitters which could be elegantly solved by these radioluminescence luminogens," says Professor of Mechanical and Materials Engineering, Dr Tang.

"Not only do they pinpoint bone and soft tissue damage for better diagnosis and treatment but we suggest further studies could see these AIE-based materials with multifunctionalities used for improved drug delivery, biosensors, bioimaging, and tissue engineering."

Lead author on the journal article in Aggregate, Dr Tavokoli, how based at the Centre for Health Technologies at University of Technology Sydney, says the next generation of fluorescent gels could also capitalise on additional light-emitting properties making them attractive for different applications.

The latest work not only explores a series of inorganic AIE systems but also "fundamentally helps to understand both the unconventional organic and inorganic clusteroluminescence phenomena, Professor Tang concludes.

Scientists develop eco-friendly pollen sponge to tackle water contaminants

A team of scientists led by Nanyang Technological University, Singapore (NTU Singapore) has created a reusable, biodegradable sponge that can readily soak up oil and other organic solvents from contaminated water sources, making it a promising alternative for tackling marine oil spills.

Made of sunflower pollen, the sponge is hydrophobic - it repels water - thanks to a coat of natural fatty acid on the sponge. In lab experiments, the scientists showed the sponge's ability to absorb oil contaminants of various densities, such as gasoline and motor oil, at a rate comparable to that of commercial oil absorbents.

Oil spills are difficult to clean up, and result in severe long-lasting damage to the marine ecosystem. Conventional clean-up methods, including using chemical dispersants to break oil down into very small droplets, or absorbing it with expensive, unrecyclable materials, may worsen the damage. 

So far, the researchers have engineered sponges that measure 5 cm in diameter. The research team, made up of scientists from NTU Singapore and Sungkyunkwan University in South Korea, believes that these sponges, when scaled up, could be an eco-friendly alternative to tackle marine oil spills.

Professor Cho Nam-Joon from the NTU School of Materials Science and Engineering, who led the study, said: "By finetuning the material properties of pollen, our team successfully developed a sponge that can selectively target oil in contaminated water sources and absorb it. Using a material that is found abundantly in nature also makes the sponge affordable, biodegradable, and eco-friendly."

This study builds on NTU's body of work on finding new uses for pollen, known as the diamond of the plant kingdom for its hard exterior, by transforming its tough shell into microgel particles. This soft, gel-like material is then used as a building block for a new category of environmentally sustainable materials. 

Last year, Prof Cho, together with NTU President Professor Subra Suresh, led a research team to create a paper-like material from pollen as a greener alternative to paper created from trees. This 'pollen paper' also bends and curls in response to changing levels of environmental humidity, a trait that could be useful for soft robots, sensors, and artificial muscles. 

Prof Cho, who also holds the Materials Research Society of Singapore Chair in Materials Science and Engineering, added: "Pollen that is not used for plant pollination is often considered biological waste. Through our work, we try to find new uses for this 'waste' and turn it into a natural resource that is renewable, affordable, and biodegradable. Pollen is also biocompatible. It does not cause an immunological, allergic or toxic reaction when exposed to body tissues, making it potentially suitable for applications such as wound dressing, prosthetics, and implantable electronics."

The findings were published in the scientific journal Advanced Functional Materials in March.

Building a sponge from pollen

To form the sponge, the NTU team first transformed the ultra-tough pollen grains from sunflowers into a pliable, gel-like material through a chemical process akin to conventional soap-making. 

This process includes removing the sticky oil-based pollen cement that coats the grain's surface, before incubating the pollen in alkaline conditions for three days. The resulting gel-like material was then freeze-dried.

These processes resulted in the formation of pollen sponges with 3D porous architectures. The sponges were briefly heated to 200°C - a step that makes their form and structure stable after repeatedly absorbing and releasing liquids. Heating also led to a two-fold improvement in the sponge's resistance to deformation, the scientists found.

To make sure the sponge selectively targets oil and does not absorb water, the scientists coated it with a layer of stearic acid, a type of fatty acid found commonly in animal and vegetable fat. This renders the sponge hydrophobic while maintaining its structural integrity.

The scientists performed oil-absorption tests on the pollen sponge with oils and organic solvents of varying densities, such as gasoline, pump oil, and n-hexane (a chemical found in crude oil). 

They found that the sponge had an absorption capacity in the range of 9.7 to over 29.3 g/g . This is comparable to commercial polypropylene absorbents, which are petroleum derivatives and have an absorption capacity range of 8.1 to 24.6 g/g.

They also tested the sponge for its durability and reusability by repeatedly soaking it in silicone oil, then squeezing the oil out. They found that this process could go on for at least 10 cycles. 

In a final proof-of-concept experiment, the team tested the ability of a sponge 1.5cm in diameter and 5mm in height to absorb motor oil from a contaminated water sample. The sponge readily absorbed the motor oil in less than 2 minutes. 

"Collectively, these results demonstrate that the pollen sponge can selectively absorb and release oil contaminants and has similar performance levels to commercial oil absorbents while demonstrating compelling properties such as low cost, biocompatibility, and sustainable production," said Prof Cho, the corresponding author of this study. 

Going forward, the researchers plan to scale up the size of pollen sponges to meet industry needs. They are also looking to collaborate with non-governmental organisations and international partners to conduct pilot tests with pollen sponges in real-life environments. 

"We hope our innovative pollen materials can one day replace widely-used plastics and help to curb the global issue of plastic pollution," said Prof Cho.

The opportunities and risks of digitalization for sustainable development

A systemic focus on risks and benefits of digital technologies

INSTITUTE FOR ADVANCED SUSTAINABILITY STUDIES E.V. (IASS)

Research News

 

Digitalisation can support transitions towards a more sustainable society if technologies and processes are designed in line with suitable criteria. This requires a systemic focus on the risks and benefits of digital technologies across the three dimensions of sustainable development: the environment, society, and the economy. This is the conclusion of a study prepared by a team of researchers at the Institute for Advanced Sustainability Studies (IASS) in Potsdam. Applying this precautionary approach to digitalisation requires the active involvement of developers, users, and regulators.

Digitalisation is a complex and dynamic process often regarded as the fourth major innovation cycle in human history. The use of a systemic risk-benefit perspective could shed light on the links and interdependencies between digital technologies and the environmental, economic, and social dimensions of sustainability, emphasise the team of researchers at the IASS.

The flexibility of digital services creates important opportunities for efforts to achieve sustainability goals. However, this can also lead to path dependencies that are difficult to reverse or otherwise correct unless they are discovered at an early stage. These closely intertwined opportunities and risks call for informed and judicious decision-making in order to foster sustainable development.

Digital innovations will not deliver the 17 UN Sustainable Development Goals (SDGs) as a matter of course; instead, the development of digital innovations must be guided by:

• a systemic perspective that acknowledges the connections and interdependencies between their environmental, economic and socio-cultural impacts,
• a professional technology assessment informed by interdisciplinary insights, and
• an inclusive decision-making style that facilitates broad participation in the development of digital services.

Digital products help reduce demand for energy and raw materials

What else will it take to foster more sustainable outcomes? Co-author and research group leader at the IASS, Pia-Johanna Schweizer, explains: "Ensuring that all sectors of society have access to digital media and possess the digital literacy needed to use them is vital to delivering an inclusive digital transformation. We also need fast and reliable Internet access nationwide - including in rural areas." Similarly, targeted support is needed for small and medium-sized enterprises as they modernize their processes.

The development of digital products and production processes that reduce energy and material demand are also important building blocks for a sustainable digital future, says co-author Grischa Beier. As Pia-Johanna Schweizer explains "Above all, it is crucial to establish clear rules for data security and data sovereignty. If these challenges are not adequately addressed, acceptance of digital innovations is likely to erode and efforts towards a sustainable digitalisation process may be jeopardized."

Finally, new societal initiatives are needed to help shape an enabling environment for the development of sustainable digital technologies and services. The three authors recommend a participatory process in which stakeholders co-design the objectives, rules and regulations for a governance structure that engages with the Sustainable Development Goals of the United Nations.

Study finds late night snacks may hurt your workplace performance

NORTH CAROLINA STATE UNIVERSITY

Research News

 P

A recent study finds that unhealthy eating behaviors at night can make people less helpful and more withdrawn the next day at work.

"For the first time, we have shown that healthy eating immediately affects our workplace behaviors and performance," says Seonghee "Sophia" Cho, corresponding author of the study and an assistant professor of psychology at North Carolina State University. "It is relatively well established that other health-related behaviors, such as sleep and exercise, affect our work. But nobody had looked at the short-term effects of unhealthy eating."

Fundamentally, the researchers had two questions: Does unhealthy eating behavior affect you at work the next day? And, if so, why?

For the study, researchers had 97 full-time employees in the United States answer a series of questions three times a day for 10 consecutive workdays. Before work on each day, study participants answered questions related to their physical and emotional well-being. At the end of each workday, participants answered questions about what they did at work. In the evening, before bed, participants answered questions about their eating and drinking behaviors after work.

In the context of the study, researchers defined "unhealthy eating" as instances when study participants felt they'd eaten too much junk food; when participants felt they'd had too much to eat or drink; or when participants reporting having too many late-night snacks.

The researchers found that, when people engaged in unhealthy eating behaviors, they were more likely to report having physical problems the next morning. Problems included headaches, stomachaches and diarrhea. In addition, when people reported unhealthy eating behaviors, they were also more likely to report emotional strains the next morning - such as feeling guilty or ashamed about their diet choices. Those physical and emotional strains associated with unhealthy eating were, in turn, related to changes in how people behaved at work throughout the day.

Essentially, when people reported physical or emotional strains associated with unhealthy eating, they were also more likely to report declines in "helping behavior" and increases in "withdrawal behavior." Helping behavior at work refers to helping colleagues and going the extra mile when you don't have to, such as assisting a co-worker with a task that is not your responsibility. Withdrawal behavior refers to avoiding work-related situations, even though you're at your workplace.

The researchers also found that people who were emotionally stable - meaning people who are better able to cope with stress because they're less emotionally volatile - suffered fewer adverse effects from unhealthy eating. Not only were emotionally stable people less likely to have physical or emotional strains after unhealthy eating, their workplace behaviors were also less likely to change even when they reported physical or emotional strains.

"The big takeaway here is that we now know unhealthy eating can have almost immediate effects on workplace performance," Cho says. "However, we can also say that there is no single 'healthy' diet, and healthy eating isn't just about nutritional content. It may be influenced by an individual's dietary needs, or even by when and how they're eating, instead of what they're eating.

"Companies can help to address healthy eating by paying more attention to the dietary needs and preferences of their employees and helping to address those needs, such as through on-site dining options. This can affect both the physical and mental health of their employees - and, by extension, their on-the-job performance."

The researchers also pointed to a variety of research questions that could be addressed moving forward.

"One confounding variable is that the way our questions were phrased, we may be capturing both unhealthy eating behaviors and unhealthy drinking behaviors related to alcohol," Cho says.

"That's something we will want to tease out moving forward. And while we focused on evening diet, it would be interesting to look at what people are eating at other times of day. Are there specific elements of diet that affect behavioral outcomes - such as sugar or caffeine content? Can there be positive effects of unhealthy eating, such as when people eat comfort foods to help cope with stress? This promises to be a rich field of study."
