Montgomery County, Md. Initiative Could Improve Health, Reduce Costs

COLLEGE PARK, Md. – An intervention to connect low-income uninsured and Medicaid patients to a reliable source of primary health care shows promise for reducing avoidable use of hospital emergency departments in Maryland. A University of Maryland School of Public Health study evaluating the results of the intervention was published this week in the May issue of the journal Health Affairs

For twenty years, use of hospital emergency departments has been on the rise in the United States, particularly among low-income patients who face barriers to accessing health care outside of hospitals, including not having an identifiable primary health care provider. Almost half of emergency room visits are considered “avoidable.” The Emergency Department-Primary Care Connect Initiative of the Primary Care Coalition, which ran from 2009 through 2011, linked low-income uninsured and Medicaid patients to safety-net health clinics. 

“Our study found that uninsured patients with chronic health issues – such as those suffering from hypertension, diabetes, asthma, COPD, congestive heart failure, depression or anxiety – relied less on the emergency department after they were linked to a local health clinic for ongoing care,” says Dr. Karoline Mortensen, assistant professor of health services administration at the University of Maryland School of Public Health and senior researcher. “Connecting patients to primary care and expanding the availability of these safety-net clinics could reduce emergency department visits and provide better continuity of care for vulnerable populations.”  

Funded by a grant from the Centers for Medicare & Medicaid Services and the Maryland Department of Health and Mental Hygiene, the initiative engaged all five of the hospitals operating in Montgomery County, Maryland at the time, and four safety-net clinics serving low-income patients. Using “patient navigators,” individuals trained to help patients find the care they need and can afford, these hospitals referred more than 10,000 low-income, uninsured and Medicaid patients who visited emergency departments to four local primary care clinics, with the goal of encouraging them to establish an ongoing relationship with the clinic and reduce their reliance on costly emergency department care. 

Two hospitals in Montgomery County who participated in the intervention continued the program after the initial grant period concluded because of the benefits they saw for patients and for reducing emergency department visits and associated costs. These hospitals are currently testing a new version of the intervention specifically deigned to link emergency department patients with behavioral health conditions to appropriate community-based services. 

While hospital administrators and health policy experts throughout the country are recognizing that access to primary care improves continuity of care for patients and reduces avoidable use of emergency departments, the implications of this project are particularly important for hospitals in Maryland, which are now operating under a unique all-payer model for hospital payments. Within this new payment structure, Maryland hospitals will have to meet ambitious spending, quality of care, and population health goals. Reducing avoidable use of emergency departments can help in reaching these goals.

The project provides promise not only for hospitals in Maryland but throughout the nation to improve health care experiences and outcomes for their patients. Shared learning systems were an integral component of the project so participants were learning from each other and sharing best practices throughout the project and that learning has now been documented and can be replicated in other communities.

“This was an incredibly rewarding project to work on,” says Barbara H. Eldridge, Manager of Quality Improvement at the Primary Care Coalition. “We created a learning system that permits us to sustain improved communication between patients and their providers, between hospital discharge planners and community based clinics, and across five hospitals operating in Montgomery County.” The initiative has proven successful in Montgomery County, Maryland and is being replicated in communities in other parts of the country.

UMD Researchers Study Brain Circuits and Social Interactions in Children with Autism

Psychology faculty awarded $2.6 million to study brain pathways associated with social interactions in autism

COLLEGE PARK, Md. — A research team from the University of Maryland Department of Psychology received a $2.6 million grant from the National Institutes of Mental Health (NIMH) to investigate whether certain brain networks in children with autism spectrum disorders make social interaction more difficult than for typically developing children.

“While it is clear that atypical social interaction plays an important role in autism, we still do not understand what may be going on in the brain to account for these difficulties,” said Dr. Elizabeth Redcay, an assistant professor of psychology, who is leading the five-year study.

While other researchers have attempted to answer this question using more traditional methods, Dr. Redcay and her team will use an innovative, interactive approach to examine how brain circuits change during social interactions in real-time while children are undergoing a functional MRI scan.

Both typically developing children and children with autism spectrum disorders between the ages of seven and 14 will visit UMD to complete activities and games in the Developmental Social Cognitive Neuroscience Lab, and then to undergo a brain scan at the university’s Neuroimaging Center. Researchers will spend a significant amount of time prior to the scans getting to know the children and making them comfortable with the process by having them practice lying still inside a mock scanner decorated to resemble a spaceship. Once inside the real machine, children will be able to hear and see an experimenter through an image projected onto a mirror. As the experimenter and child engage in back-and-forth conversation and go through various scenarios, researchers will be watching for changes in various areas of the brain.

“We actually have children receive live feedback from a social partner (the experimenter) so if they do something like perform a task quickly enough, such as pushing a button to answer a question, then they can see their social partner come online and give them a positive thumbs up or some kind of positive reward,” Dr. Redcay explained. “This way we can study these brain networks and how these brain networks are interacting with each other when children are actually having social interactions.”

Gaining a better understanding of the systems underlying social interaction could lead to the development of new strategies to help children on the autism spectrum overcome social challenges, which may improve other aspects of life as well.

“The amount that a child shares with others and that motivation to engage with others in social settings is important to forming friendships and close personal relationships, but it’s much more than that too,” Redcay said. “It’s directly related to how many words a child learns, how good they are at understanding people even years later so basically that fundamental ability of being able to engage in social interactions successfully is really important early in development in autism but continues to be important throughout the life span.

Collaborators on Dr. Redcay’s research team include UMD Psychology Professor Dr. Luiz Pessoa, Dr. Audrey Thurm from the National Institutes of Health and several UMD graduate and undergraduate students.

Use it or Lose it: UMD Study Shows Stopping Exercise Decreases Brain Blood Flow

August 29, 2016

AthleteCOLLEGE PARK, Md. - We all know that we can quickly lose cardiovascular endurance if we stop exercising for a few weeks, but what impact does the cessation of exercise have on our brains? New research led by University of Maryland School of Public Health researchers examined cerebral blood flow in healthy, physically fit older adults (ages 50-80 years) before and after a 10-day period during which they stopped all exercise. Using MRI brain imaging techniques, they found a significant decrease in blood flow to several brain regions, including the hippocampus, after they stopped their exercise routines.

“We know that the hippocampus plays an important role in learning and memory and is one of the first brain regions to shrink in people with Alzheimer’s disease,” says Dr. J. Carson Smith, associate professor of kinesiology and lead author of the study, which is published in Frontiers in Aging Neuroscience in August 2016. “In rodents, the hippocampus responds to exercise training by increasing the growth of new blood vessels and new neurons, and in older people, exercise can help protect the hippocampus from shrinking. So, it is significant that people who stopped exercising for only 10 days showed a decrease in blood flow to brain regions that are important for maintaining cognitive health.”

The study participants were all “master athletes,” defined as people between the ages of 50 and 80 (average age was 61) who have at least 15 years history of participating in endurance exercise and who have recently competed in an endurance event. Their exercise regimens must have entailed at least four hours of high intensity endurance training each week. On average, they were running ~36 miles (59 km) each week or the equivalent of a 10K run a day! Not surprisingly, this group had a V02 max above 90% for their age. This is a measure of the maximal rate of oxygen consumption of an individual and reflects their aerobic physical fitness.

Dr. Smith and colleagues measured the velocity of blood flow in brain with an MRI scan while they were still following their regular training routine (at peak fitness) and again after 10 days of no exercise. They found that resting cerebral blood flow significantly decreased in eight brain regions, including the areas of the left and right hippocampus and several regions known to be part of the brain’s “default mode network” – a neural network known to deteriorate quickly with a diagnosis of Alzheimer’s disease. This information adds to the growing scientific understanding of the impact of physical activity on cognitive health.

“We know that if you are less physically active, you are more likely to have cognitive problems and dementia as you age,” says Dr. Smith. “However, we did not find any evidence that cognitive abilities worsened after stopping exercising for just 10 days. But the take home message is simple - if you do stop exercising for 10 days, just as you will quickly lose your cardiovascular fitness, you will also experience a decrease in blood brain flow.”

Dr. Smith believes that this could have important implications for brain health in older adults, and points to the need for more research to understand how fast these changes occur, what the long term effects could be, and how fast they could be reversed when exercise is resumed.

Department of Energy funds UMD research on safer, better lithium-ion battery technology as part of a
$57 million investment to improve vehicle efficiency

COLLEGE PARK, Md. – A team of researchers at the University of Maryland Energy Research Center (UMERC) recently was awarded a $1.25 million grant from the Department of Energy (DOE) for research to develop better, safer Lithium-ion battery technology. 

Credit: Department of EnergyUMD’s award is part of a total of $57 million in DOE funding for 35 projects aimed at reducing the cost and improving the efficiency of plug-in electric, alternative fuel, and conventional vehicles.  The Department of the Army is contributing an additional $2.2 million through the Advanced Vehicle Power Technology Alliance to support projects specifically focused on advanced high-voltage electrolytes for batteries and advanced engine and powertrain technologies to improve vehicle fuel efficiency.  The UMERC project and most of the other 34 projects will support the goals of EV Everywhere, a DOE program that aims to make plug-in electric vehicles (PEVs) as affordable and convenient as gasoline-powered vehicles by 2022.

UMD’s DOE-funded project is to design “self‐healing, 3‐D conformal solid state electrolytes to prevent dendrite formation and achieve high battery cycle life.” Researchers have long known that lithium-ion batteries that currently power electric vehicles, laptops and smartphones could have significantly higher energy if their graphite anodes (electrodes) were replaced by lithium metal anodes. Hampering this change, however, has been the so-called dendrite problem. Over the course of several battery charge/discharge cycles microscopic fibers of lithium, called “dendrites,” sprout from the surface of the lithium electrode and spread like kudzu across the electrolyte solution until they reach the battery’s other electrode (cathode). An electrical current passing through these dendrites can short-circuit the battery, causing it to rapidly overheat and in some instances catch fire.

UMERC researchers already are rapidly developing safer, higher capacity and longer lasting lithium batteries based on a number of different technological approaches. The new DOE-funded project will build on technology developed by UMERC Director Eric Wachsman and Department of Materials Science and Engineering professors Liangbing Hu and Yifei Mo

This team has already shown breakthroughs in developing the first flexible, solid-state, ion-conducting membrane based on a 3D Li-ion conducting ceramic nanofiber network. In June in the Proceeding of the National Academy of Sciences (PNAS), they published research on the development of a flexible solid battery electrolyte with superior thermal stability and electrochemical stability to high voltage. 

“This technology is unique in its ability to replace current flammable organic liquid electrolyte systems in lithium-ion batteries with a solid electrolyte that enables both higher energy density lithium-metal anodes and the use of conventional battery manufacturing facilities,” says Wachsman.

Hu adds that “the 3D interconnected network with percolated garnet nanofibers can lead to high ion conductivity and great flexibility, which are important for safe, solid state battery fabrications and operations.”

COLLEGE PARK, Md. - The University of Maryland has been named to Campus Pride’s 2016 “Best of the Best” Top 30 list of LGBTQ-friendly colleges and universities. The listing highlights the positive efforts UMD and other top institutions have made to promote diversity, inclusion and safety for LGBTQ students.

Campus Pride is the leading national educational organization for LGBTQ and ally college students and campus groups building future leaders and safer, more LGBTQ-friendly colleges and universities. For eight years, the list has highlighted the most LGBTQ-inclusive colleges and universities when it comes to policy, program and practice in higher education.

“We are truly honored by this recognition,” said Luke Jensen, Director of the Lesbian, Gay, Bisexual and Transgender Equity Center at UMD. “By naming the University of Maryland among the ‘best of the best’ for the fifth time, Campus Pride acknowledges the many campus collaborations at UMD needed to create an LGBTQ-friendly campus and the continuing effort necessary to maintain our national leadership in LGBTQ campus inclusion.”

The “Best of the Best” list is based on ratings from the Campus Pride Index, a national benchmarking tool which self-assesses LGBTQ-friendly policies, programs and practices. Each campus updates their index annually and uses the Campus Pride benchmarking tool to make improvements for LGBTQ life on campus. In order to be in the top 30, an institution has to score the highest percentages in the LGBTQ-friendly benchmarks. UMD was the only Maryland/Washington, D.C.-area university to make the 2016 list.

“Prospective students and their families today expect colleges to be LGBTQ-friendly.  They want to know what LGBTQ programs, services and resources are available on the campus - and which are the 'Best of the Best,'” said Shane Windmeyer, executive director of Campus Pride and creator of the Campus Pride Index. “Now more than ever, there are colleges that are recruiting LGBTQ youth - and they are investing in a campus that is fully supportive of LGBTQ students. This Top 30 list showcases those campuses leading the way.”

During the 2015-2016 academic year, UMD launched two new initiatives, including Q-TEAM (Queer Training, Education And Mindfulness) and the LGBT Sports Summit. Spearheaded by the LGBT Equity Center, Q-TEAM was a year-long series of sessions led by experts on the health and wellness needs of LGBTQA+ communities. The LGBT Sports Summit, an initiative of the Department of Intercollegiate Athletics, focused on LGBT inclusion in intercollegiate sports. 

In addition to UMD’s nationally recognized LGBT Studies Program, continuing programs during the past year included Quelcome, the annual welcome event at the beginning of each academic year; Hearth (formerly Queer Camp), an annual fall weekend retreat attended primarily by incoming students; an Alternate Spring Break to New York City concentrated on LGBTQ youth; Lavender Leadership Honor Society and the spring Lavender Leadership Retreat, groundbreaking programs building and supporting LGBTQ student leaders; and the 18th annual Lavender Graduation celebrating UMD’s LGBTQ graduates.

Partnership offers affordable, local housing to students and alumni who are ambitiously pursuing university-affiliated companies

COLLEGE PARK, Md. – The University of Maryland has partnered with several student and alumni startup companies to create the area’s first “Startup Village.” Part of the university’s Greater College Park initiative to rapidly revitalize the Baltimore Avenue corridor and academic campus, the Startup Village was created to help bridge the gap for student and alumni entrepreneurs as they grow their business ideas on campus and work toward launching them in the market.

After spending hours commuting from out of state to College Park every day, a group of UMD entrepreneurs were on the lookout for affordable housing options close to the university to give them more time to work on their startups. Through a partnership with UMD, the students and alumni worked together to renovate a house just on the edge of campus and create the Startup Village. Starting as one house with the potential to grow, the current residents of the Startup Village include The Q Truck, Javazen, Ready Box and David Mitchell Clothing. On any given day, several other businesses can be collaborating or working out of the flexible space.

“At the University of Maryland, the spirit of entrepreneurship extends well beyond graduation,” said Ken Ulman, the university’s chief strategy officer for economic development. “We see more and more that alumni want to stay in the area because they recognize the role UMD is playing in the innovation economy. Being part of the Startup Village allows these entrepreneurs to not only work on growing their companies, but contribute to their community as well.”

The Startup Village is an informal living-learning experience for UMD alumni and current students who are in the processing of launching a business or currently run a business. Living together helps the entrepreneurs create a robust support and resource network of operations experts, legal advisors, accountants and business professionals.

“Startup Village allows everyone to focus fully on their companies without the hassle of commuting,” says UMD alumnus David Engle, co-founder of The Q Truck. “Our self-care and self-starter attitudes are what we work to foster in a house of entrepreneurs living together – a culture which the Startup Village aims to incubate and spread to the wider community.” Engle co-founded the Startup Village with Eric Golman, co-founder of Javazen.

“College Park is a strong supporter of local businesses and we are thrilled to welcome these new and innovative companies into our community,” said College Park Mayor Patrick L. Wojahn. “I look forward to finding creative ways to partner with these entrepreneurs to make the Startup Village a growing part of our city’s culture.”

Front page of Maryland Free Press (Hagerstown, Md., November 21, 1862) featuring an account of General George McClellan’s farewell to his soldiers after he was removed from command of the Union Armies. The masthead reads “Common consent is the only legitimate basis of government.”COLLEGE PARK, Md. – The University of Maryland Libraries received a grant of $250,000 from the National Endowment for the Humanities (NEH) to extend its successful project to digitize historic Maryland newspapers.

The grant was one of only 14 awarded through the NEH’s National Digital Newspaper Program, which grants funds to make the nation's historic newspapers broadly and freely accessible. This is the third such grant the University Libraries have received to support this effort.

Since being awarded its first NEH newspaper grant in 2012, the University of Maryland Libraries have digitized more than 200,000 pages from Baltimore, Hagerstown and Cumberland newspapers, with efforts well under way to represent every region of Maryland. The project has received a total of $865,000 from the NEH.

Project leaders plan to digitize approximately 100,000 newspaper pages over a two-year period. 

Published between 1690 and 1963, the newspapers reflect the political, economic and cultural history of Maryland.  One noteworthy example is the Frostburg Mining Journal, a prominent union publication from western Maryland.

Advertisement for “The Wonder Car” featuring what “any sane man wants when he buys an automobile:” a promise to take him anywhere and bring him back. Cost for the automobile (without electric starter) was $695.  (The Democratic advocate, Westminster, Md., April 20, 1915.)“Support of this program is especially meaningful because it points to a partnership with the Maryland State Archives and Frostburg State University, both of which are providing access to either the newspapers themselves or microfilm copies,” said Babak Hamidzadeh, Dean of University Libraries. “Together we are able to expand access to these historic documents citizens of the state and researchers around the world.” 

The newspaper project reflects Hamidzadeh’s efforts to showcase the technical know-how of the University Libraries, which are home to information managers, programmers, systems analysts and digitization experts.

“Ongoing support from NEH parallels the increased growth of our digitization program,” said Robin Pike, who manages the digitization and conversion operations throughout the University Libraries. “It is an honor to receive the third grant from this major federal granting agency. We’ve demonstrated that we have the expertise and capacity to continue expanding this project.”

Pike’s staff, sometimes in concert with external vendors, digitize numerous formats including books, posters, archival manuscripts, photographs, slides, negatives and audiovisual media, such as the Liz Lerman Dance Exchange video collection and UMD football films.

The National Digital Newspaper Program, a partnership between NEH and Library of Congress, is a long-term effort to develop an internet-based, searchable database of U.S. newspapers. The Maryland newspapers are added to a growing collection of more than 10 million digitized newspaper pages freely available to the public at Chronicling America

Wood Windows are Cooler than Glass

UMD study shows natural microstructures in transparent wood key to lighting and insulation advantages

COLLEGE PARK, Md. – Engineers at the A. James Clark School of Engineering at the University of Maryland demonstrate in a new study that windows made of transparent wood could provide more even and consistent natural lighting and better energy efficiency than glass.    

Wood composite as an energy efficient building material: Guided sunlight transmittance and effective thermal insulation. In a paper published in the peer-reviewed journal Advanced Energy Materials, the team, headed by Liangbing Hu of UMD’s Department of Materials Science and Engineering and the Energy Research Center lay out research showing that their transparent wood provides better thermal insulation and lets in nearly as much light as glass, while eliminating glare and providing uniform and consistent indoor lighting.  The findings advance earlier published work on their development of transparent wood.  

The transparent wood lets through just a little bit less light than glass, but a lot less heat, said Tian Li, the lead author of the new study.  “It is very transparent, but still allows for a little bit of privacy because it is not completely see-through. We also learned that the channels in the wood transmit light with wavelengths around the range of the wavelengths of visible light, but that it blocks the wavelengths that carry mostly heat,” said Li. 

The team’s findings were derived, in part, from tests on tiny model house with a transparent wood panel in the ceiling that the team built. The tests showed that the light was more evenly distributed around a space with a transparent wood roof than a glass roof.

The channels in the wood direct visible light straight through the material, but the cell structure that still remains bounces the light around just a little bit, a property called haze. This means the light does not shine directly into your eyes, making it more comfortable to look at. The team photographed the transparent wood’s cell structure in UMD’s Advanced Imaging and Microscopy (AIM) Lab.

Transparent wood still has all the cell structures that comprised the original piece of wood. The wood is cut against the grain, so that the channels that drew water and nutrients up from the roots lie along the shortest dimension of the window. The new transparent wood uses theses natural channels in wood to guide the sunlight through the wood.   

As the sun passes over a house with glass windows, the angle at which light shines through the glass changes as the sun moves. With windows or panels made of transparent wood instead of glass, as the sun moves across the sky, the channels in the wood direct the sunlight in the same way every time. 

"This means your cat would not have to get up out of its nice patch of sunlight every few minutes and move over," Li said. "The sunlight would stay in the same place. Also, the room would be more equally lighted at all times."

Working with transparent wood is similar to working with natural wood, the researchers said.  However, their transparent wood is waterproof due to its polymer component. It also is much less breakable than glass because the cell structure inside resists shattering. 

The research team has recently patented their process for making transparent wood.  The process starts with bleaching from the wood all of the lignin, which is a component in the wood that makes it both brown and strong.  The wood is then soaked in epoxy, which adds strength back in and also makes the wood clearer.  The team has used tiny squares of linden wood about 2 cm x 2 cm, but the wood can be any size, the researchers said.
