A review of the use of dual-energy X-ray absorptiometry (DXA) in rheumatology.

The principal use of dual-energy X-ray absorptiometry (DXA) is to diagnose and monitor osteoporosis and therefore reduce fracture risk, associated morbidity, and mortality. In the field of rheumatology, DXA is an essential component of patient care because of both rheumatologists' prescription of glucocorticoid treatment as well as the effects of rheumatological diseases on bone health. This review will summarize the use of DXA in the field of rheumatology, including the concern for glucocorticoid-induced osteoporosis, as well as the association of osteoporosis with a sampling of such rheumatologic conditions as rheumatoid arthritis (RA), systemic lupus erythematosus, ankylosing spondylitis, juvenile idiopathic arthritis, and scleroderma or systemic sclerosis.

Improving access to mental health care for children: the Massachusetts Child Psychiatry Access Project.

Background: Inadequate access to care for mentally ill children and their families is a persistent problem in the United States. Although promotion of pediatric primary care clinicians (PCCs) in detection, management, and coordination of child mental health care is a strategy for improving access, limitations in training, time, and specialist availability represent substantial barriers. The Massachusetts Child Psychiatry Access Project (MCPAP), publicly funded with 6 regional consultation teams, provides Massachusetts PCCs with rapid access to child psychiatry expertise, education, and referral assistance.

Online batch recipe adjustments for product quality control using empirical models: application to a nylon-6,6 process.

The application of batch profile characterization tools to enhance process understanding by uncovering the signature of the primary disturbances on the profiles and its effect on the product quality is illustrated on a nylon-6,6 process. The historical profile data for the fixed recipe operation are systematically studied to understand the primary disturbances affecting the process, and it is shown that good online predictions of the final product quality are possible much before the completion of the batch from the available measurement profiles. A simple online recipe adjustment strategy based on the predicted quality deviation from the target is proposed.

Pulmonary immunoreactive calcitonin in the African green monkey (Cercopithecus aethiops): Anatomic distribution.

The hormone calcitonin, which occurs predominantly within the C cells of the mammalian thyroid gland, is also found within the pulmonary endocrine cells of the epithelium of the tracheobronchial tree. A study was made of the distribution of immunoreactive calcitonin (iCT) in the African green monkey. Using two different region-specific antisera, the total respiratory iCT comprised 2.
