No Meeting Week
Enclave Holiday Support Schedule
July 4th - July 8th
To help our community with a positive and productive workload, CD2H-N3C has scheduled several “No Meeting Weeks” throughout the year. The Next N3C No Meeting Week will beJuly 4th to July 8th.
Most meetings will be canceled. Impromptu meetings can still occur to push through action items as needed during no meeting week.
Workgroups and Domain Teams should check with their Leads to determine meeting schedules for that week.
N3C support will continue with regular operations. If you have any trouble logging on to the enclave, please contact [email protected].
Enclave support for the holiday weekend
Friday, July 1st:
- Level 1 support (e.g. basic platform and product-related questions) will operate at full capacity.
- Level 2 support (i.e. issues that require more hands-on help or knowledge of N3C contextual information will be off).
Friday July 4th:
- Enclave support will be off, but we will have an on-call rotation for platform outages and critical issues.
Future No Meeting Weeks:
4th Quarter: November 7-11
The Community Forum will not take place during these weeks

What the Research Community is Saying about N3C |

Johanna Loomba
iTHRIV CTSA Director of Informatics
N3C Logic Liaison Lead
N3C Neurological Domain Team Lead

"N3C has revolutionized public health research in the United States by providing data, technology, and organizational infrastructure to support agile and organic team science during a national crisis. Cross-institutional, interdisciplinary research teams have self-organized around important areas of investigation, proving that the harmonization and co-location of health record data not only supports local data cleaning and quality enhancements, but also results in cross-pollination of best practices. The Logic Liaison team emerged through cross-domain dialogue and resulted in a set of community code templates designed to streamline data synthesis and cleaning. The templates have resulted in greater analytic alignment across domain teams and supported rapid onboarding and training of students and experts alike. I look forward to watching the tools, environment and community continue to evolve." |

N3C's NLP (Natural Language Processing) Data Enhancement Status
810,000,000+ NLP Facts
617,000+ Patients
Across 4 Sites
|
|
Currently, four sites have successfully submitted NLP (Natural Language Processing) facts into the N3C Enclave. NLP facts are derived from processing clinical notes and only contain coded information. Sites process the text locally and only submit coded data to the N3C enclave. In total there are 810 million NLP facts from 617,000 patients that have been ingested. These numbers will continue to grow as additional sites successfully submit their NLP facts to the N3C Enclave. |

N3C on NPR's Marketplace Tech Interview |
|
Marketplace’s Meghan McCarty Carino speaks with Emily Pfaff, an assistant professor of medicine at the University of North Carolina at Chapel Hill who uses artificial intelligence to analyze electronic health records, looking for patterns that might better identify the syndrome and treat patients. Pfaff said some of the most common markers the algorithm detects are fatigue, shortness of breath, and frequent doctor visits.

Rare Diseases with Bryan Laraway, MS
With over 10,000 known rare diseases collectively affecting nearly 10% of the population, rare disease patient populations represent unique and varied cohorts for the study of COVID. Bryan Laraway and Melissa Haendel presented initial exploratory findings from their work to analyze the impact of SARS-CoV-2 infection on rare disease patients, including the prevalence of rare disease patients in the N3C enclave with and without SARS-CoV-2 infection, the COVID severity in SARS-CoV-2-positive rare disease patients, as well as the predicted incidence of long-COVID in those patients. Work is currently underway to identify and characterize additional rare disease populations within the enclave as well as more in-depth analyses examining the effect of pre-existing rare disease phenotypes on COVID severity and outcomes. Future analyses will leverage the diverse expertise of the research team and will utilize semantic technologies including ontologies, semantic similarity phenotype matching, and rare disease clustering.
While a regular meeting schedule is still being determined, those interested in joining the research team may contact Bryan Laraway at [email protected] for further details on joining the rare disease and COVID DUR.

N3C In the News
In this issue, Emily Pfaff and colleagues show that machine learning analysis of electronic health records could be crucial in diagnosing patients with long COVID.
TUESDAY, June 14, 2022 (HealthDay News) — Patients are at increased risk for new-onset psychiatric conditions in the early postacute phase of COVID-19 infection, according to a letter to the editor published in the June issue of World Psychiatry.
Scientists have urged patients and health care staff to be more proactive about addressing mental health concerns as a new study identifies a higher risk of psychiatric disorders among people suffering from COVID-19.
Covid-19 may increase the risk of developing a psychiatric disorders in the months after infection with the SARS-CoV-2 virus, according to a study conducted in the US.
The COVID-19 pandemic has demanded a huge effort to identify the risks associated with poor outcomes. The focus has been particularly relevant in patients with immune-mediated inflammatory diseases and those on therapies that suppress the immune system. Small early observational studies looked worrisome, but as data from larger studies became available a consistent picture became evident. Demographic risk factors such as age and comorbidity are really the salient factors, with some risk from underlying disease and a few specific therapeutic agents, such as rituximab.
COVID-19 patients were at a 25 percent greater risk of developing a psychiatric disorder in the months after infection than those who experienced other respiratory illnesses, according to a recent study.
COVID-19 may increase the risk of developing a psychiatric disorder in the months after infection with the SARS-CoV-2 virus, according to a study conducted in the US. Researchers at the Oregon State University (OSU) in the US found that COVID-19 patients had about 25 per cent increased risk of developing a psychiatric disorder in the four months following their infection, compared with people who had other types of respiratory tract infections.
A recent Oregon State University study found that COVID-19 patients had a roughly 25% increased risk of developing a psychiatric disorder in the four months following their infection, compared with people who had other types of respiratory tract infections.
As the number of people reporting persistent, and sometimes debilitating, symptoms from COVID-19 increases, researchers have struggled to pinpoint exactly how common so-called "long COVID" is, as well as how to clearly define exactly who has it or who is likely to get it.
A research team supported by the National Institutes of Health has identified characteristics of people with long COVID and those likely to have it.
A research team supported by the National Institutes of Health has identified characteristics of people with long COVID and those likely to have it.
Clinical scientists have explored de-identified electronic health record data in the National COVID Cohort Collaborative(N3C), a National Institutes of Health-funded national clinical database, using machine learning models to help decipher characteristics of individuals with long COVID and attributes that may help identify such patients using information from medical records.
Machine learning models may be able to predict who will develop Covid-19, FDA authorizes an at-home test to detect the coronavirus, flu, and respiratory syncytial virus (RSV), and more in this week's roundup of Covid-19 news.

N3C Domain Teams
N3C Domain Teams enable researchers with shared interests to analyze data within the N3C Data Enclave and collaborate more efficiently in a team science environment. They include multidisciplinary Clinical Domains composed of subject matter experts, statisticians, informaticists, and machine learning specialists who focus on clinical questions surrounding COVID-19's impact on health. Cross-Cutting Domains have a varied focus that applies to multiple domains. These teams provide an opportunity to collect pilot data for grant submissions, train algorithms on larger datasets, inform clinical trial design, learn how to use tools for large-scale COVID-19 data, and validate results. N3C encourages researchers of all levels to join a Domain Team that represents their interests, or to suggest new clinical areas to explore.

Offboarding
As we have recently crossed the 2-year mark for the COVID-19 pandemic, it is a good inflection point to identify colleagues who have completed their efforts with CD2H/N3C projects and have transitioned to other great opportunities. If this is you, or perhaps your colleague, we would like to ask that you complete this 2-minute form (Bit.ly/cd2h-offboarding-form) to offboard CD2H and or N3C projects. You can continue to just get the newsletter if you wish.
We thank you for your tireless efforts in CD2H/N3C projects and look forward to working with you on many other projects.
