RDMD for IBM patients

A partnership with RDMD for those with IBM

RDMD helps rare disease patients retrieve, access, and accelerate research with their medical records. They work with your hospitals so you can be in control of your medical records data. If you choose to participate in research, de-identified information from your records can be shared with researchers to advance the understanding of your condition. And, you are in control of the sharing of these records at all times through informed consent and opting in-or-out of sharing.

NEW: Live Video Session with RDMD. See details.

Identification of Predictors for Interstitial Lung Disease in Myositis Patients: A Systematic Review

Interstitial lung disease (ILD) is a well-recognized complication in the spectrum of diseases known as the idiopathic inflammatory myopathies (IIM). Individual studies of IIM-associated ILD have shown variation in the progression of the disease and, because of small sample sizes, prognostic factors seem to be difficult to identify. Prognostic factors are those characteristics or conditions that can be used to estimate or predict outcomes of disease.

New Myositis Support Community

Introducing the NEW Myositis Support Community! The Myositis Support Community is similar to Facebook, however, it provides a more safe and secure environment for the sensitive topics we discuss as people living with, and those caring for people with, myositis (idiopathic inflammatory myopathies).

Education and Support are key

We have hosted several myositis experts to lead live, online video sessions throughout 2018. All sessions were held online with live participation. These sessions were recorded and we hope you will take advantage of the educational opportunities these provide for you and your family members.

Find the videos on our YouTube page and share with your loved ones.
