OHSU addiction researchers find opportunity for intervention

Honora EnglanderPatients with substance use disorders often suffer from and are hospitalized due to chronic illnesses that cause medical conditions such as abscesses and cardiovascular disease. Hospitalization temporarily disrupts drug use and can bring patients an increased awareness of mortality, the harmful effects of substance use, and its costs on relationships, including parenting.

Some evidence also suggests that initiating medication-assisted treatment during these hospitalizations can increase the likelihood of patients engaging in substance use disorder treatment after discharge. However, these interventions have shown high rates of attrition in treatment. Little research has been conducted on factors associated with these individuals’ readiness to change.

Now, a team of OHSU addiction medicine researchers has published in the Journal of General Internal Medicine findings that provide insights into the patient, provider, and health system factors that can be used to initiate and coordinate addiction care.

Addiction medicine specialist Honora Englander, M.D., associate professor in the School of Medicine Division of Hospital Medicine and medical director of the OHSU Community & Clinical Integration Medicine Teaching Service, led the research, which was designed to better understand factors that impact readiness to change.

The study used patient perspectives to identify influences on their motivation to change and to engage in treatment during hospitalization. Researchers interviewed hospitalized adults admitted to OHSU medical or surgical units who reported as high-risk for alcohol or drug use. The team found that while many participants were interested in treatment, the participants also saw significant barriers to obtaining care after discharge, including homelessness and trauma. Patients suggested higher success rates could be influenced by improved care coordination and more timely transition from inpatient to outpatient treatment. Participants valued providers who understood substance use disorders and the importance of treatment choice.

The research found that hospitalization provides an excellent opportunity for treatment of substance use disorders, and that understanding patient perspectives on treatment options might improve the outcomes of these interventions. The researchers reported that the patient’s voice is critical in shaping system improvements and best practices.

As part of the Springer Nature SharedIt initiative, the paper is available to the public.
In addition to Englander, the study was conducted by Todd Korthuis, M.D., M.P.H., associate professor in the OHSU-PSU School of Public Health and in the School of Medicine Division of Internal Medicine; Christine Velez Klug, M.S.W., instructor in Community & Clinical Integration and the PSU School of Social Work; and Christina Nicolaidis, M.D., M.P.H., professor and senior scholar in the PSU Social Determinants of Health Initiative and associate professor in the School of Medicine Division of Internal Medicine and OHSU-PSU School of Public Health.

OHSU research yields insight into aspirin’s anti-cancer effect

Acetylsalicylic acid, a.k.a. aspirin.

Acetylsalicylic acid, a.k.a. aspirin.

The anti-inflammatory and anti-platelet properties of aspirin have made it the subject of intensive investigation for over a century. More recently, aspirin use has been correlated with reduced long-term risk of some cancers, particularly colorectal cancer. The reasons remain unknown, as does the degree to which the effect comes from direct inhibition of cancer cells and how much is due to inhibition of platelet activation and function.

A study recently completed by a team of OHSU researchers and published in the American Journal of Physiology—Cell Physiology suggests the benefit of aspirin may be due to its effect on platelets rather than acting directly on tumor cells.

In a series of experiments with cultured cells, a team led by Owen McCarty, Ph.D., chair of the Department of Biomedical Engineering in the School of Medicine, showed that inhibition of platelets with low doses of aspirin cuts the signaling link between platelets and some cancer cells, which in turn knocks back cancer growth.

It is not yet known whether the cascade of effects observed in cell cultures works the same way in people. The new findings are not sufficient to justify taking aspirin solely to help prevent cancer. Aspirin has an effect mediated by platelets that may work in concert with aspirin’s anti-inflammatory properties to oppose malignant cell growth, and low doses of aspirin might eventually prove a safe and effective way to prevent cancer in patients at risk.

The research was supported by grants from the Altarum Institute, the National Institutes of Health, and the American Heart Association.

Supplemental funding available for research on sex/gender influences

The recently implemented NIH policy requiring grant applicants to consider sex as a biological variable in the design of basic and pre-clinical animal studies has prompted considerable discussion. Translating this policy into action is complex. For example, the cost associated with expanding the scope of a study to include additional cell lines or study animals is a pressing issue for many investigators.

The Office of Research on Women’s Health is responding to this concern by providing administrative supplements to support research highlighting the impact of sex/gender influences and/or sex and gender factors in basic, preclinical, clinical and behavioral studies. Supplemental applications, within the scope of the parent application, may include the following approaches:

  • Adding the opposite sex: Adding animal or human subjects, tissues or cells of the sex opposite to those used in the parent grant to allow sex/gender-based comparisons.
  • Increasing sample size: Adding more animal or human subjects, tissues or cells to a sample  to increase the power of a study for analysis of  sex/gender differences.
  • Conducting new experiments or comparative analyses: Developing new experimental approaches or comparative analyses of existing samples or datasets to investigate the role of sex/gender.

Supplemental applications must address at least one objective from Goals 1-3 of the NIH Strategic Plan for Women’s Health Research:

  1. Increase sex differences research in basic science studies.
  2. Incorporate findings of sex/gender in the design and development of new technologies, medical devices, and therapeutic drugs.
  3. Actualize personalized prevention, diagnostics, and therapeutics for girls and women.

The objectives of Goals 2 and 3 are of higher programmatic importance and applications studying one or more of these goals will be given higher consideration. For applications that address Goal 1, of special interest are studies to understand the influence of biological sex on cells, primary cell cultures, immortalized cell lines, transformed cells, and tissue explants.

The Office of Research on Women’s Health intends to commit $3,000,000 in FY 2017 to fund 30 awards. Supplemental application budgets are limited to $65,000 in direct costs but additional indirect costs may also be requested. The award project period is limited to one year. The parent grant must have at least 18 months of active support remaining from the supplement application due date, which is February 13, 2017. Guidelines on submitting your application can be found here. Still have questions? Contact your Grants and Contracts Administrator.

OHSU’s Erick Turner to present at next Data Jamboree, Dec. 16

Join the OHSU Library and Computational Biology Program for December’s Data Jamboree. This month’s event will focus on the role of open content and data in advancing biomedical research and human health. Erick Turner, M.D., Associate Professor at OHSU and Staff Psychiatrist at the Portland VA Medical Center, will introduce OpenTrialsFDA, a current finalist for the highly competitive Open Science Prize.

OpenTrialsFDA is a platform developed by Turner and associates that aims to increase access to and the utility of FDA drug approval packages that often contain information on clinical trials that have never been published.  When these data are integrated into a systematic review or meta-analysis, it can sometimes dramatically shift a drug’s risk-benefit ratio. Although the FDA makes the reviews available via its web portal Drugs@FDA, the documents are notoriously difficult to search and aggregate. As a consequence, they are rarely used by clinicians and researchers, despite their immense value. OpenTrialsFDA intends to change this by allowing researchers, clinicians, the public, developers, and third party platforms to access, search, and build upon this data.

Friday, Dec. 16
2:30 – 5:00 PM (hackathon will continue past 5:00)
Collaborative Life Sciences Building (CLSB), 3A003
Food & Drink provided

Turner’s keynote talk will be followed by an overview of the NIH’s new clinical trial data sharing requirements and two concurrent hands-on sessions:

  • Searching the OpenTrialsFDA website, understanding the contents of an FDA drug approval package, and how the data can benefit different use cases, such as meta-analysis and systematic reviews.
  • An OpenTrialsFDA hackathon using the OpenTrials API.  Attendees will have the opportunity to use their research, development, clinical, and visualization expertise (to name a few) to explore, present, and build upon the OpenTrials data and the OpenTrialsFDA application. Please note, no technical expertise is required, as there will be multiple ways of contributing.

All are welcome to attend, including OHSU faculty, students, and staff as well as Portland area science enthusiasts and developers!

Community Partnership Program funds 10 new cancer research projects across the state

OHSU researchers brought in $389 million in extramural funding in fiscal year 2016. But OHSU also funds projects across Oregon through mechanisms like the Knight Cancer Institute’s  Community Partnership Program.

The OHSU Knight Cancer Institute has announced grant funding for ten projects around the state that target communities’ cancer-related needs — from prevention through survivorship. These grants provide funding and resources to help develop programs and guide projects toward evidence-based practices and evaluation measures. The program also offers opportunities for networking and collaborating with OHSU faculty.

To date, Community Partnership Program grants have funded 52 projects in 33 of Oregon’s 36 counties, with 89 percent of projects targeting rural communities. The program has funded a variety of projects, including expanding cancer screenings, prevention through healthy behaviors, and survivorship support.

Carsten Schultz and lab develop new imaging platform for profiling cell signaling networks

Cellular development, tissue repair, immunity, and normal homeostasis rely on cells perceiving and appropriately responding to their microenvironment. While significant knowledge exists on the individual aspects of these cell signaling pathways, the question persists on how cell signaling networks integrate and process information from multiple extracellular cues. Understanding these processes may help develop therapies to more effectively treat diseases such as cancer and diabetes that result from errors in processing information.

A study published December 8 by Carsten Schultz, Ph.D., chair of the OHSU School of Medicine’s Department of Physiology and Pharmacology, in Cell Chemical Biology reports development of a new imaging platform for monitoring cell signaling network activity that may, when combined with gene expression studies, answer long-standing questions about how this complex communication system works.

Dr. Schultz and his team developed a method that allows comprehensive system-level analysis of multiple signaling pathway dynamics under identical conditions. Such a method supports research into how cellular signaling networks integrate information from the extracellular environment, how they evoke specific cellular responses, and, most importantly, how normal signaling is rewired over the course of a disease.

The team combined cell microarray technology with Förster resonance energy transfer (FRET) biosensors and live-cell imaging. The study demonstrated that the platform enabled multi-dimensional data generation in a single experiment and successfully demonstrated the effect of perturbing the network by drugs. They also found that crosstalk of two growth factors produces distinct activity patterns.

The platform may in the future be applied to develop comprehensive models of signaling networks and help investigate the mechanisms of action, as well as side effects of therapeutic treatments. The findings may provide information relevant to disease progression and prognosis, design of therapeutic treatment, and drug discovery.

The research team included Dmitry Kuchenov, Vibor Laketa, and Frank Stein from the European Molecular Biology Laboratory (EMBL) Cell Biology and Biophysics Unit in Heidelberg, Germany, and Florian Salopiata and Ursula Klingmüller of the Translational Lung Research Center Heidelberg, a German Center for Lung Research site. Schultz joined OHSU in the fall of 2016 as chair of the Department of Physiology and Pharmacology.

The work was supported by the Schultz team at the European Molecular Biology Laboratory, the German Federal Ministry of Education and Research, the DFG (SFB 1129), and the Joachim Herz Foundation. The Klingmüller group was supported by the German Federal Ministry of Education and Research through the LungSysII consortium, and the German Center for Lung Research.

OHSU’s Erick Turner and team finalists for Open Science Prize: voting open through Jan. 6

Alongside the growing availability of high-value open data for research are key obstacles — discoverability and the ability to access and use that data. The global science competition Open Science Prize was launched by the Wellcome Trust, US National Institutes of Health, and the Howard Hughes Medical Institute to encourage new ways to remove these obstacles. In the first phase of this new initiative, six international teams received prizes to develop prototypes. The teams presented their prototypes at the BD2K Open Data Science Symposium in Washington, D.C., on December 1.

A bigger picture

Contrasting the journal version of antidepressant trials with FDA information.

OpenTrialsFDA, one of the finalist prototypes, was presented by Erick Turner, MD, associate professor in the OHSU Psychiatry Department and staff psychiatrist at the Portland VAMC, along with collaborators Dr. Ben Goldacre, senior clinical research fellow in the Centre for Evidence Based Medicine at the University of Oxford, and Open Knowledge International.

The prototype is a new application of existing open data techniques and code designed to improve access to drug approval packages submitted to and made available by the Food and Drug Administration. These documents contain detailed information about the methods and results of clinical trials and often contain unpublished information on clinical trials.

The FDA databases are notoriously difficult to access, search, and aggregate. Much of the information in these packages is only available in image form and is not searchable. The OpenTrialsFDA application converts documents into searchable text, scrapes all the relevant data and documents from the FDA documents, runs Optical Character Recognition across all documents, links this information to other clinical trial data, and presents it through a user-friendly web interface.

The OpenTrialsFDA prototype definitely fits the Open Science Prize goal: to make the outputs from science and the research process more broadly accessible.

Voting is open from now until 6 January 2017. The public is invited to help select the most promising and innovative prototype from the six finalists. One prototype will receive the grand prize of $230,000.
