Amyloid deposition in and around the joints is usually associated with underlying conditions such as multiple myeloma, chronic infections or inflammation (secondary amyloidosis).
Should we continue to use animal models for the purpose of drug development, the reproducibility of any improvement in outcome should be addressed more extensively in animals with different genetic background and underlying conditions such as age or co-morbidities and by using various infection models.
The at-risk groups include pregnant and post partum women, children under two years old, and people with underlying conditions such as respiratory problems.
Our use of microspheres was aimed at simulating increases in pulmonary vascular resistance, the common pathway for pathophysiologic mechanisms underlying conditions such as PVD[29].
This may be associated with underlying conditions such as polyps, ulcerative colitis, hemorrhoids and malignancy.
Fourthly, in our study underlying conditions, such as COPD, diabetes and lifestyle risk factors such as smoking, were often present.

However, the clinical signs and symptoms of bacterial and viral pneumonia can overlap and are often confounded by underlying conditions such as immunosuppression and extrapulmonary complications [ 7- 9].
Whether these delayed deaths are associated with underlying conditions such as HIV, SCD or other immune defects have not been formally investigated.
Second, we were only able to evaluate the role of underlying conditions such as SCD and HIV only in those who have an established diagnosis.
