New service offers fast, standardized results for eating disorder experts

Eating disorder researchers at the University of Colorado Anschutz Medical Campus have developed a new procedure that takes detailed patient questionnaires and generates a fast, standardized score for mental health professionals.

The service is available free to doctors, psychologists and other health professionals working with patients who have eating disorders.

Dr. Guido Frank, associate professor of psychiatry, is an expert in eating disorders

“Despite all the research, the fact is we still have limited treatments available in the field of eating disorders,” said Guido Frank, MD, eating disorder expert and associate professor of psychiatry and neuroscience at the University of Colorado School of Medicine. “But if we clinicians use similar validated assessments across disciplines and providers, the field of eating disorders will be more cohesive and more evidence-based.”

Frank and his fellow researchers, developed a web-based service where therapists can sign in patients. The patients fill out questionnaires developed for those with disorders like anorexia nervosa, bulimia and binge eating. Using a computer program, the questionnaire is automatically scored with a number that health care providers can use to understand the nature of the illness. The scoring process keeps the patients anonymous.

“The therapist receives the results and can discuss them with the patient,” Frank said. “It is purely a free service in the hopes that it will help.”

Frank said the system is unique in offering a standardized scoring method while bringing the latest science to practitioners in the field.

“Sometimes the work we do is hard to translate into the real world so we trying to close that research gap,” he said. “This shared knowledge, I believe, will help us  personalize treatment and provide evidence-based interventions that are tailored to individual needs.”

Program reduces high ED use, increases primary care visits for most vulnerable patients

Researchers at the University of Colorado Anschutz Medical Campus  have found that a community-based program aimed at high users of hospital emergency departments (EDs), reduced ED visits and hospital admissions,  while increasing use of primary care providers.

“Many programs have tried to tackle the problem of high utilizers of hospital emergency departments. These are usually people who are on Medicaid,” said the study’s first author Roberta Capp, MD, an assistant professor of emergency medicine at the University of Colorado School of Medicine. “But this is the first program to show that care coordination actually works.”

The study was published October 2, 2017 in the journal Health Affairs http://bit.ly/2fJUIaq.

Dr. Roberta Capp, assistant professor of emergency medicine, is the first author on the study.

Capp and her fellow researchers implemented and evaluated Bridges to Care (B2C), an ED-initiated, community-based program. It was one of four sites funded by a Center for Medicare and Medicaid Innovations grant.

The program was led by Rutgers University Center for State Health Policy and developed in collaboration with four Colorado stakeholders including an urban academic hospital, a network of 13 local federally qualified health centers, a mental health clinic and a community advocacy organization.

Researchers compared participants in the B2C program, which focused on Medicaid eligible high ED users, with patients who had received standard care with respect to ED utilization, hospital admission and primary care use.

High ED users were identified as adults who had two or more ED visits or hospital admissions within the last 180 days.

During the six months after B2C enrollment, the participants had 29.7 percent fewer ED visits and 30 percent less hospitalizations. At the same time, they had 123 percent more primary care visits than the control subjects.

“There is a perspective from multiple stakeholders that high users of the ED are difficult patients,” Capp said. “But this study shows that patients use the ED because of there are serious barriers to care.

ED care makes up 5 – 6 percent of all healthcare expenses.

Previous studies have shown that providing care-coordination services and better access to primary care can reduce waste in healthcare spending. A number of programs addressing low-income, high users of EDs have been implemented with mixed results. Most were hospital-based with little community involvement.

But Capp said the B2C intervention is the first aimed at high users of EDs to combine active outreach in the ED with multidisciplinary, community-based services.

It offers intensive medical, behavioral health and social care coordination services. That includes providing a care coordinator, a health coach, a behavioral health specialist, a community health worker and frequent home visits.

Each patient was given a personally tailored, 60-day care plan that included, but was not limited to assistance with getting housing resources, refugee services, access to transportation, help with applying for insurance and disability benefits, setting up primary and specialty care and filling prescriptions.

“We believe that our success stems from bringing together different healthcare systems, breaking down silos between disciplines and focusing on continuity of care in the outpatient setting,” Capp said.

The study shows just how intense the services offered to this population must be to reduce their reliance on EDs. One reason is that they often have chronic diseases, including mental illness.

“We learned that active outreach in the ED is key to ensuring successful high utilizer and enrollment and engagement,” the study said.

For example, early in the study, the team used call back lists and enrolled only 80 patients in seven to eight months, but when a community health worker was embedded in the ED, enrollment over the same period of time tripled.

“For a program like B2C to be effective, behavioral health services must be provided to high utilizers to ensure comprehensive, multidisciplinary care,” Capp said.

She hopes federal lawmakers examining the Affordable Care Act will evaluate the program as a more cost efficient way of providing high quality care to the most vulnerable.

Co-authors of the study from CU Anschutz include Benjamin Honigman, MD, professor of emergency medicine; Jennifer Wiler, MD, associate professor of emergency medicine and Richard Lindrooth, PhD, professor in the department of health systems, management and policy.

An Epic Sprint to aid clinics

In February 2011, the University of Colorado Anschutz Medical Campus took a major step toward fundamentally changing its health care delivery. The change would eventually affect every provider, researcher and staff member on the campus and beyond – and the reverberations continue today.

The revolution began with a handful of ambulatory clinics at University of Colorado Hospital that began using the Epic electronic health record (EHR). The aim: shelve dozens of discrete applications and towering paper stacks in favor of a single system that would allow all providers to view a patient’s entire medical record online.

Sprint Team Conference Room

The Epic implementation included a massive training effort and a phased, multi-year rollout that ensconced the EHR on the Anschutz Medical Campus and at UCH satellite clinics. With the formation and growth of UCHealth, Epic now links hospitals and clinics up and down the Front Range and beyond.

But the challenges of ­working efficiently and effectively with an EHR remain. Memorizing sequences of clicks in record charting can be frustrating for providers focused on patient care. Patients now have an electronic conduit to their providers through My Health Connection; figuring out how best to route and respond to questions can be challenging and time-consuming for clinics. The basic Epic framework requires ongoing customization to meet the needs of dozens of specialists and subspecialists – most them with the CU School of Medicine – and their UCHealth patients.

These challenges help to explain why Epic training, in the form of tip sheets, webinars, emails, and other support, has never ended. The past year has produced a new twist: a dedicated team that gives clinic providers and staff focused, face-to-face help with making the most of the EHR.

On the run

The Sprint team, as it’s called, consists of Epic analysts, trainers, and a project manager, as well as a nurse and physicians who combine clinical and information technology skills. Together they help to define the clinical and operational needs of providers and staff and collaborate with IT, clinical and other experts to meet them. Their guiding principle: people learn best when they have face-to-face help from people who are interested in listening to them, answering their questions and solving their problems.

“It’s a collaborative effort,” said Christine Gonzalez, the Sprint team’s project manager. “When you need to make rapid changes, nothing beats live help. Providers and staff feel safe with working one-on-one.”

The Sprint team is a response to a problem that is both local and national, said Amber Sieja, MD, a physician informaticist for the Anschutz Medical Campus and an internist with the CU School of Medicine. Maintaining paper medical records might have been cumbersome, but for many providers meeting the demands of an electronic system has made practicing medicine more difficult than ever.

“The problem we face is that providers are burned out with their clinical practice,” Sieja said. She noted that in national surveys, providers routinely identify EHRs as a major contributor to that problem. “Locally, our providers have told us the EHR takes up too much time,” she added. “That’s our problem to solve.”

That’s a tall order, however. Epic is a dynamic tool that receives annual upgrades as well as ongoing customized changes for specific clinical areas. How to communicate the changes to the couple of thousand providers with the School of Medicine and UCHealth Medical Group? The Epic team has tried spreading the word with regularly scheduled Skype videos, newsletters, tip sheets, and open training sessions. It’s all fallen well short of reaching anywhere near most providers, Sieja said.

“The message we got is ‘we want somebody in our clinics,’” she said.

Left to right, back row: Amber Sieja, MD – physician informaticist; Todd Andrews – lead analyst; Dan Golightly – analyst; Rob Lewis – analyst; Dan Kroening – trainer; Diane Pruitt, RN – clinical informaticist. Left to right, front row: Scott Carpenter – lead trainer; Barbara Noble – trainer; Christine Gonzalez – project manager; Megan Cortez – analyst; Tally Talyai, PA – physician informaticist.

That demand spurred the creation of the first “Sprint” in 2016. Sieja, fellow physician informaticist Katie Markley, MD, and UCHealth Chief Medical Information Officer CT Lin, MD, put together a team that parachuted into the Endocrinology Clinic at UCH for a two-week, hands-on helping stint. Their work drew praise from both providers and staff for helping to decrease burnout, reduce charting time and improve patient care.

The Endocrinology pilot wasn’t perfect, Sieja said. Most importantly, it showed that future Sprint projects would need more lead time to prioritize clinic needs, schedule rooms and meeting times, identify potential new EHR builds, and so on. They settled on 90 days of preparation, said Sieja, who used that time to develop a curriculum for the Neurology Clinic at UCH.

The Sprint project in Neuro, which began in January 2017, represented a major challenge. Its nearly 100 providers handled more than 26,000 patient visits in 2016. It also includes eight subspecialties, all with specific patient care needs. A major part of the work involved meeting with “clinical content leaders” to identify priorities for new Epic builds, such as flowsheets to help ensure that patients with neuromuscular diseases like ALS (amyotrophic lateral sclerosis, or Lou Gehrig’s disease) and other complex neurologic conditions receive evidence-based standards of care.

“These are tools that allow us to track patients over time,” said Laura Strom, MD, an epilepsy specialist who helped to lead the Sprint effort in the Neurology Clinic. “They are invaluable in Epic.” The flowsheets, however, had to be built from scratch, a time-consuming process, she added. All told, seven subspecialties requested and received customized builds as part of the Sprint project.

The Sprint team spent a pair of two-week stints, separated by a one-week break, in the Neurology Clinic, wrapping up the work in February. Much of the effort focused on helping providers use Epic more efficiently for their basic work: pulling needed information from patient charts; ordering labs, imaging studies and other tests; responding to patient questions and referral requests; and preparing to address patients’ chief complaints in advance of the visit. Providers learned to use templates, preference lists, keywords and phrases, and other shortcuts to reduce the number of clicks – and therefore time – they spend at the keyboard, Sieja said.

Making work simpler

The key is to reduce frustration with practical help, said Gonzalez, who handles the planning, coordination and other logistical details of each Sprint mission.

“I feel we come in to take a good tool [Epic] that we already have and make it better,” Gonzalez said. Many providers on the Anschutz Medical Campus, she noted, have not had additional guidance in using Epic since the first go-live six-plus years ago.

“Who doesn’t need more training?” Gonzalez asked. She cited the example of a UCHealth Colorado Springs provider who was surprised when she found how much time she could save by using Epic’s Dragon voice-recognition software for her progress notes instead of typing. The shortcut helped her get home to her family earlier.

“She told us the change helped her to become a better mother,” Gonzalez said.

Strom said more than 90 percent of the Neurology Clinic’s providers received the Sprint training in some form. The attention generally helped to increase individuals’ confidence in using shortcuts in Epic to trim their documentation time, she said. One example: “dictionaries” Epic uses to translate shorthand for frequently used terms into the real word.

“People applauded the one-on-one teaching,” Strom said. Some critics of Epic who had viewed it as nothing more than a “billing tool,” she added, changed their minds after the Sprint initiative.

“They saw that Epic could be used to take better care of patients and to help to improve the growth of understanding about their disease,” Strom said. A post-intervention survey showed that both providers and staff viewed Epic in a more favorable light than they had before the Sprint team worked with them. For example, the percentages of those who agreed that the clinic improved its use of the EHR and the patient care it provided increased significantly in both groups.

The Sprint team followed the Neurology Clinic assignment with a regular schedule of visits to UCHealth facilities in Northern and Southern Colorado as well as the Anschutz Medical Campus. For example, they worked with the respective Hematology/Oncology practices at UCHealth’s Memorial Hospital in Colorado Springs and Poudre Valley Hospital in Fort Collins. They wrapped up a four-week stint with the OB/Gyn Clinic at UCH – another with close to 100 providers and several subspecialties – on July 21. They are booked on a two-week on, one-week off schedule through June 2018 (with some extra time off for the next Epic upgrade this October), Gonzalez said.

Important challenges remain, including how to ensure that the positive changes in clinics visited by Sprint continue. Sieja points to the importance of super users and clinical content leaders to “carry the improvements forward.” Sprint success also brings to light questions of “scalability,” said Chief Medical Information Officer Lin, noting that it could be increasingly difficult for a single Sprint team to meet clinic demand. For now, the team splits to work with clinics with fewer providers and subspecialists.

“We need people to bring along others at the basic level,” Strom agreed. “But the sense of what is possible with Epic is now much more keen. More people are saying, ‘We really can use this tool.’”

Researchers find creosote bush could treat Giardia and brain-eating amoeba infections

Compounds produced by the creosote bush, a desert shrub common to American Southwest, exhibit potent anti-parasitic properties against two deadly parasites responsible for Giardia infections (Giardia lamblia) and the amoeba that causes an often-lethal form of encephalitis (Naegleria fowleri), according to researchers at the Skaggs School of Pharmacy and Pharmaceutical Sciences at CU Anschutz and UC San Diego.

Daniel LaBarbera, PhD, associate professor of drug discovery and medicinal chemistry at Skaggs School of Pharmacy and Pharmaceutical Sciences.
Daniel LaBarbera, PhD, associate professor of drug discovery and medicinal chemistry at Skaggs School of Pharmacy and Pharmaceutical Sciences.

The findings, published online this month in PLOS Neglected Tropical Diseases, may give scientists the chance to widen their arsenal of antimicrobial agents effective against deadly parasitic infections. The current standard treatment for both infections involve antibiotics and anti-parasitic drugs.

The World Health Organization estimates giardiasis, a diarrheal illness, is linked to approximately 846,000 deaths worldwide each year. Infection usually occurs through ingestion of contaminated water or food. Though rarely lethal in the United States, it’s estimated there are more than a million cases of giardiasis in the country annually. Infections due to N. fowleri, sometimes called the `brain eating amoeba,’ are much less common than Giardia.

Compounds from the creosote bush may fight two deadly parasitic infections.

“However, it is a far deadlier parasite that is found in warm fresh waters and infects the central nervous systems of their victims through the nasal passages causing lethal brain damage known as primary amoebic meningoencephalitis (PAM),” said principal investigator Dan LaBarbera, PhD, associate professor of drug discovery and medicinal chemistry at the Skaggs School of Pharmacy and Pharmaceutical Sciences at CU Anschutz.

Due to its rapid infection cycle and high mortality rate, the CDC has been given special approval to provide the drug miltefosine to clinicians as a treatment option for N. fowleri infection. But it is still not FDA approved and has limited availability in the U.S. This new compound potentially provides a less expensive, more effective treatment option.

Scientists from CU Anschutz and UC San Diego collaborated as part of the Skaggs Scholars program, which matches investigators from Skaggs-funded schools of pharmacy with complementary expertise to discover potential drug breakthroughs. UC San Diego scientists provided expertise in parasitology, while the CU Skaggs School of Pharmacy provided expertise in natural products, compound libraries and active compounds from plants. The researchers investigated these tropical diseases because of their occurrence in Mexico and South America and found indigenous peoples treating infections with creosote compounds.

“The significance and intrigue about our study is that it shows the value of prospecting for new medicines from plants traditionally used by indigenous people as medicine,” said co-principal investigator Anjan Debnath, Ph.D., an assistant adjunct professor at Skaggs School of Pharmacy and Pharmaceutical Sciences at UC San Diego.

The creosote bush (Larrea tridentata), is a tough evergreen bush with small waxy leaves, yellow flowers and a distinctive turpentine-like scent. Native Americans in both the United States and Mexico have long used the plant for a variety of ailments, including intestinal complaints. There is also an existing body of scientific work documenting the plant’s pharmacologically active compounds, notably nordihydroguaiaretic acid (NDGA). NDGA has antiviral, antibacterial, anti-inflammatory and anticancer properties.  The study is the first to show that NDGA and five other compounds are active against both pathogenic parasites.

In other studies, NDGA has been shown to be a neuroprotective agent. It protects human monocytes and other cells and tissues through its powerful antioxidant activity.

“In our study the creosote natural product, NDGA, proved to be a more potent anti-parasitic agent against N. fowleri compared to miltefosine,” LaBarbera said. “Therefore, NDGA may lead to a more effective drug therapy option for N. fowleri infection.”

This research was funded in part, by a grant from The ALSAM Foundation and National Institutes of Health.

Major communication gaps between doctors and home health care nurses revealed

Researchers at the University of  Colorado Anschutz Medical Campus have found serious gaps in communication between physicians and home health care agencies (HHC) responsible for caring for often elderly patients discharged from hospitals. The problem, the study said, can contribute to hospital readmissions.

The research, published today in the Journal of General Internal Medicine, cites an array of communication challenges between HHC agencies and physicians following hospital discharge.

Dr. Christine Jones, assistant professor of medicine and lead author of the study.
Dr. Christine Jones, MD, MS, assistant professor of medicine and lead author of the study.

The study cited frequent discrepancies in medication lists, confusion over who was responsible to write patient care orders, inaccessible hospital records and resistance from clinicians and staff for accountability.

Led by Christine D. Jones, MD, MS, assistant professor at the University of Colorado School of Medicine, the researchers conducted six focus groups with HHC nurses from six different agencies in Colorado to ask about their general experience with caring for patients after discharge from any of their referring hospitals.

“We found that communication breakdowns can have consequences for patients,” said Jones, lead author of the study. “These are some of our most fragile patients, most are over 65, and more seamless communication is needed.”

Some of the HHC nurses interviewed complained of a lack of accountability, medical errors and difficulty in reaching doctors.

“As a general rule, I’ve been told you’re not to contact the hospitals. I actually got in trouble for contacting the hospital, trying to find out, get more information, trying to track a doctor down,” one nurse said in a focus group.

Another nurse said even if they reach a primary care physician, they often say they didn’t know the patient was in the hospital and they don’t have a report on them.

“The communication between the hospital and the primary care providers is just as bad as it is for us because the PCP’s don’t have the information,” the nurse said.

Dr. Jones said another complicating factor is that insurance often requires doctors to order HHC services. So if a nurse practitioner is providing primary care for a patient, obtaining HHC immediately becomes more difficult.

The researchers found another serious problem when it came to ordering medication. HHC nurses and staff said most of the medication lists they receive are incorrect due to the number of doctors and specialties involved.

“As hospitalists, we need to think about what happens beyond the hospital walls and how we can support our patients after discharge, especially when it comes to home health care patients who can be very vulnerable.” Jones said.

She noted that the study did not focus on any one specific hospital, but hospitals in general.

The study proposes a series of solutions to these problems including the following:

  • Hospitals and primary care physicians could provide HHC agencies direct access to Electronic Medical Records and direct phone lines to doctors.
  • Enact laws allowing nurse practitioners and physician’s assistants to write HHC orders. A bill was under consideration to do this but was not acted upon by Congress.
  • Clearly establishing accountability for hospital clinicians to manage HHC orders until a primary care physician can see a patient and help HHC nurses with questions.
  • Create better communication methods with PCPs to ensure safer transitions

“Our findings suggest that improvements to accountability and communication could address patient needs and goals, avoid medication discrepancies and ultimately improve safety for patients and HHC nurses,” Dr. Jones said.

Immune system may keep body from neutralizing HIV-1 virus

Researchers at the University of  Colorado Anschutz Medical Campus have discovered that a process protecting the body from autoimmune disease appears to prevent it from creating antibodies that can neutralize the HIV-1 virus, a finding that could possibly help lead to a vaccine that stimulates production of these antibodies.

Dr. Raul Torres, professor of immunology and microbiology at CU Anschutz
Raul Torres, PhD, professor of immunology and microbiology at the University of Colorado School of Medicine.

The study, led by Raul M. Torres, PhD, professor of immunology and microbiology at the University of Colorado School of Medicine, was published Tuesday in The Journal of Experimental Medicine.

Torres and his team sought to better understand how the body’s own immune system might be getting in the way of neutralizing the HIV-1 virus.

They knew that some patients infected with HIV-1 developed what are known as ‘broadly neutralizing antibodies,’ or bnAbs, that can protect against a wide variety of HIV-1 strains by recognizing a protein on the surface of the virus called Env. But the patients only develop these antibodies after many years of infection.

Because of shared features found in a number of HIV-1 bnAbs, researchers suspected the inability or delayed ability to make these type of protective antibodies against HIV was due to the immune system suppressing production of the antibodies to prevent the body from creating self-reactive antibodies that could cause autoimmune diseases like systemic lupus erythematosus.

At the same time, patients with lupus showed slower rates of HIV-1 infection. Scientists believe that’s because these autoimmune patients produce self-reactive antibodies that recognize and neutralize HIV-1.

The process by which the body prevents the creation of antibodies that can cause autoimmune disease is known as immunological tolerance.

Torres wanted to break through that tolerance and stimulate the production of antibodies that could neutralize HIV-1.

“We wanted to see if people could make a protective response to HIV-1 without the normal restraint imposed by the immune system to prevent autoimmunity,” Torres said.

The researchers first tested mice with genetic defects that caused lupus-like symptoms. They found that many of them produced antibodies that could neutralize HIV-1 after being injected with alum, a chemical that promotes antibody secretion and is often used in vaccinations.

Next, they treated normal mice with a drug that impairs immunological tolerance and found that they began producing antibodies capable of neutralizing HIV-1. The production of these antibodies was increased by alum injections. And if the mice were also injected with the HIV-1 protein Env, they produced potent broadly neutralizing antibodies capable of neutralizing a range of HIV-1 strains.

In every case, the production of these HIV-neutralizing antibodies correlated with the levels of a self-reactive antibody that recognizes a chromosomal protein called Histone H2A. The researchers confirmed these antibodies could neutralize HIV-1.

“We think this may reflect an example of molecular mimicry where the virus has evolved to mimic or look like a self protein,” Torres said.

Torres suggested that the difficulty in developing a vaccine against HIV-1 may be because of the ability of the virus to camouflage itself as a normal part of the body.

“But breaching peripheral immunological tolerance permits the production of cross-reactive antibodies able to neutralize HIV-1,” Torres said.

Since the research was done on animals, scientists must still determine its relevance for HIV-1 immunity in humans.

“The primary consideration will be determining whether immunological tolerance can be temporarily relaxed without leading to detrimental autoimmune manifestations and as a means to possibly elicit HIV-1 bnAbs with vaccination,” he said.

National study shows interventions like telephone calls can reduce suicides

In perhaps the largest national suicide intervention trial ever conducted, researchers at the University of  Colorado Anschutz Medical Campus and Brown University found that phone calls to suicidal patients following discharge from Emergency Departments led to a 30 percent reduction in future suicide attempts.

The study was published recently in JAMA Psychiatry.

The year-long trial, which involved 1,376 patients in eight locations nationwide, provided suicidal patients with interventions that included specialized screening, safety planning guidance and follow-up telephone calls.

Dr. Michael Allen, professor of psychiatry and emergency medicine at the Helen and Arthur E. Johnson Depression Center at CU Anschutz, co-authored the study.
Dr. Michael Allen, professor of psychiatry and emergency medicine at the Helen and Arthur E. Johnson Depression Center, co-authored the study.

“People who are suicidal are often disconnected and socially isolated,” said study co-author Dr. Michael Allen, MD, professor of psychiatry and emergency medicine at the Helen and Arthur E. Johnson Depression Center at CU Anschutz. “So any positive contact with the world can make them feel better.”

Allen is also medical director of Rocky Mountain Crisis Partners in Denver which has already implemented a similar program where counselors call suicidal patients following their discharge from Emergency Departments (EDs).

Suicide is the 10th leading cause of death in the U.S. In 2015, there were 44,193 deaths by suicide nationally. Over one million people attempt to take their own life every year.

Colorado routinely ranks among the top 10 states for suicide with about 1,000 deaths a year. Last year, it was number seven in the country. The state Legislature has set a goal of reducing suicides by 20 percent by 2024.

Allen said simply handing a suicidal patient a psychiatric referral when discharged isn’t enough.

“We call them up to seven times to check on them after discharge,” he said. “If they aren’t there we leave a message and call again. For many, this telephone call is all they get.”

The crisis center has worked with 17 of Colorado’s 88 EDs and is hoping to increase that number and eventually go statewide.

“We don’t need more brick and mortar buildings, we can reduce suicide risk by simply calling people on the phone,” Allen said.

Dr. Emmy Betz, associate professor of emergency medicine.
Dr. Emmy Betz, associate professor of emergency medicine.

His colleague and study collaborator Dr. Emmy Betz agreed.

“Telephone follow-up programs offer a great way to help bridge an ED visit to outpatient mental health care and hopefully save lives,” said Betz, an associate professor of emergency medicine at CU Anschutz who has conducted extensive research on suicide. “It would be great to see such programs become more widely implemented. Suicide is a leading cause of death, especially in Colorado, and a shortage of inpatient and outpatient mental health care options make innovative approaches like telephone counseling even more attractive.”

The study was led by Brown University and Butler Hospital psychologist Ivan Miller.

Miller, a professor of psychiatry and human behavior at the Warren Alpert Medical School of Brown University, said he was encouraged that they were able to impact suicide attempts among this population with a relatively limited intervention.

While suicide prevention efforts such as hotlines are well known, published controlled trials of specific interventions are much rarer, Miller said.

“We were happy that we were able to find these results,” he said.

This report was one of several from the Emergency Department Safety Assessment and Follow-up Evaluation (ED-SAFE) study led by Miller, Professor Edwin Boudreaux of the University of Massachusetts and Dr. Carlos Camargo of Massachusetts General Hospital and Harvard University.

Dr. Betz was the principal investigator for Colorado’s ED-SAFE site.

The trial took place in three phases to create three comparison groups. In the first phase, 497 patients received each ED’s usual treatment as a control group. In phase two universal screening was implemented and 377 patients received additional attention in the ED. In the third phase, 502 patients received the experimental intervention.

Those patients received the same Phase 2 care including additional suicide screening from ED physicians, suicide prevention information from nurses and a personal safety plan they could fill out to prepare for times when they might begin harboring suicidal thoughts again.

Over the next year, they also received periodic phone calls from trained providers at Butler Hospital in Providence, R.I., who would discuss suicide risk factors, personal values and goals, safety and future planning, treatment engagement, and problem solving.

The number of suicide attempts and the proportion of people attempting suicide declined significantly in the intervention group compared to treatment as usual. The middle group, which received only additional screening, did not show a significant drop compared to the treatment as usual group.

“This is a remarkably low cost, low tech intervention that has achieved impressive results,” Dr. Allen said.

Scientists use high tech microscope to find clue to an autoimmune disease

Using a unique microscope capable of illuminating living cell structures in great detail, researchers at the University of  Colorado Anschutz Medical Campus have found clues into how a destructive autoimmune disease works, setting the stage for more discoveries in the future.

The scientists were trying to visualize antibodies that cause neuromyelitis optica (NMO), a rare autoimmune disorder that causes paralysis and blindness. Using a custom STED (Stimulated Emission Depletion) microscope built at CU Anschutz, they were able to actually see clusters of antibodies atop astrocytes, the brain cell target of the autoimmune response in NMO.

Dr. Jeffrey Bennett, MD, PhD, is senior author of the study.

This could potentially correspond with their ability to damage the cells,” said Professor Jeffrey Bennett, MD, PhD, senior author of the study and associate director of Translational Research at the Center for NeuroScience at CU Anschutz. “We know that once antibody binds to the surface of the astrocyte, we are witnessing the first steps in the disease process.”

When that domino effect begins, it’s hard to stop. But Bennett said the ability to see the antibodies on the brain cells offers a chance to develop targeted therapies that do not suppress the body’s immune system like current treatments for the disease do.

“By applying this novel approach we can see firsthand how these antibodies work,” said the study’s lead author, John Soltys, a current student in the Medical Scientist Training Program at CU Anschutz. “We are looking at the initiation of autoimmune injury in this disease.”

The breakthrough was made possible with the STED microscope, a complex instrument that uses lasers to achieve extreme precision and clarity. It was built by physicist Stephanie Meyer, PhD, at CU Anschutz. This is the first time it has been used in a research project here.

“This would have been impossible to see with any kind of normal microscope,” said study co-author Professor Diego Restrepo, PhD, director of the Center for NeuroScience.  “We are inviting other scientists with research projects on campus to use the STED microscope.”

According to Meyer, lower resolution microscopes are blurrier than the STED due to diffraction of light. But the STED’s lasers illuminate a smaller area to acquire a higher resolution image . Unlike electron microscopes, STED users can see entire living cells at super high resolution, as they did in this study.

Restrepo said there are only a handful of STEDs in the nation and just one in Colorado.

The researchers said the discovery is the result of a unique partnership between clinical neurology, immunology and neuroscience coming together to solve a fundamental question of how antibodies can initiate targeted injury in an autoimmune disease.

“These are the building blocks that we can use to carry our research to the next level,” Bennett said.

The study was published this week in Biophysical Journal.

Cannabinoids may soothe certain skin diseases, say CU Anschutz researchers

Cannabinoids contain anti-inflammatory properties that could make them useful in the treatment of a wide-range of skin diseases, according to researchers at the University of Colorado Anschutz Medical Campus.

The new study, published online recently in the Journal of the American Academy of Dermatology, summarizes the current literature on the subject and concludes that pharmaceuticals containing cannabinoids may be effective against eczema, psoriasis, atopic and contact dermatitis.

Dr. Robert Dellavalle, associate professor of dermatology, is senior author of the study.

Currently, 28 states allow comprehensive medical cannabis programs with close to 1 in 10 adult cannabis users in the U.S. utilizing the drug for medical reasons. As researchers examine the drug for use in treating nausea, chronic pain and anorexia, more and more dermatologists are looking into its ability to fight a range of skin disease.

“Perhaps the most promising role for cannabinoids is in the treatment of itch,” said the study’s senior author Dr. Robert Dellavalle, MD, associate professor of dermatology at the University of Colorado School of Medicine.

He noted that in one study, eight of 21 patients who applied a cannabinoid cream twice a day for three weeks completely eliminated severe itching or pruritus. The drug may have reduced the dry skin that gave rise to the itch.

Dellavalle believes the primary driver in these cannabinoid treatments could be their anti-inflammatory properties.  In the studies he and his fellow researchers reviewed, they found that THC (tetrahydrocannabinol) the active ingredient in marijuana, reduced swelling and inflammation in mice.

At the same time, mice with melanoma saw significant inhibition of tumor growth when injected with THC.

“These are topical cannabinoid drugs with little or no psychotropic effect that can be used for skin disease,” Dellavalle said.

Still, he cautioned that most of these studies are based on laboratory models and large-scale clinical trials have not been performed. That may change as more and more states legalize cannabis.

Dellavalle said for those who have used other medications for itch and skin disease without success, trying a cannabinoid is a viable option especially if it has no psychotropic effect. He did not recommend such medications for cancer based on current evidence.

“These diseases cause a lot of problems for people and have a direct impact on their quality of life,” he said. “The treatments are currently being bought over the internet and we need to educate dermatologists and patients about the potential uses of them.”

The other authors of the study include Jessica S. Mounessa, BS, Julia A. Siegel, BA and Cory A. Dunnick, MD.
