TL;DR: For individuals with no cardiovascular risk factors as well as for those with 1 or more risk factors, those who are obese in middle age have a higher risk of hospitalization and mortality from CHD, cardiovascular disease, and diabetes in older age than those who is normal weight.

TL;DR: The Compression of Morbidity hypothesis—positing that the age of onset of chronic illness may be postponed more than the age at death and squeezing most of the morbidity in life into a shorter period with less lifetime disability—is reviewed.

TL;DR: Criteria for the classification of hypersensitivity vasculitis were developed by comparing 93 patients who had this disease with 714 control patients with other forms of vasculopathy, finding that the presence of 3 or more of these criteria was associated with a sensitivity of 71.0% and a specificity of 83.9%.

TL;DR: The American College of Rheumatology Subcommittee on Classification of Vasculitis of the Diagnostic and Therapeutic Criteria Committee developed classification criteria for 7 forms of vasculitis: polyarteritis nodosa, Churg-Strauss syndrome, Wegener's granulomatosis, hypersensitivity vasculopathy, Henoch-Schönlein purpura, giant cell (temporal) arteritis, and Takayasu arteritis.

TL;DR: Assessing self-reported physical function/disability with the Health Assessment Questionnaire Disability Index and other instruments has become central in arthritis research and item response theory and computerized adaptive testing techniques can increase reliability and statistical power.
