Rheumatoid arthritis is an autoimmune systemic disease characterized mainly by inflammatory compromise of diarthrodial joints. Multiple drug therapies have been developed to control the activity of rheumatoid arthritis, among them, the first line of disease-modifying antirheumatic drugs (DMARD), and novel drug therapies such as the anti-TNF alpha therapy, with satisfactory clinical outcomes.Despite this positive fact, the use of this therapy implies the risk of producing negative effects due to its mechanism of action, which has been associated with multiple infections, especially tuberculosis, making it necessary to use screen tests before resorting to this kind of drugs...

Symptom management in older adults, including pain and distressing non-pain symptoms, can be challenging. Medications can cause side effects that worsen quality of life or create other symptoms, and polypharmacy itself can be detrimental in older adults. Cannabinoids may offer a way of managing selected symptoms with fewer side effects. Medical marijuana is an important area of study for older adults because of the side effects of other medications. It is also important for Baby Boomers, who are likely to have more experience with marijuana than older adults of previous generations...

Infants who have graduated from a neonatal intensive care unit require close follow-up because they have a greater chance of experiencing later motor and cognitive difficulties; however, these difficulties are often challenging to identify at an early age. The General Movement Assessment is a low-cost and highly reliable tool that can indicate abnormal neurological development in young high-risk infants, but it has not yet been widely implemented in the United States. In this review, we discuss the literature about the use of the General Movement Assessment in high-risk infants and how to implement the tool in a clinical setting...

REVIEW
Lauren E Kelly, Yashwant Sinha, Charlotte I S Barker, Joseph F Standing, Martin Offringa
Pharmacodynamic (PD) endpoints are essential for establishing the benefit-to-risk ratio for therapeutic interventions in children and neonates. This article discusses the selection of an appropriate measure of response, the PD endpoint, which is a critical methodological step in designing pediatric efficacy and safety studies. We provide an overview of existing guidance on the choice of PD endpoints in pediatric clinical research. We identified several considerations relevant to the selection and measurement of PD endpoints in pediatric clinical trials, including the use of biomarkers, modeling, compliance, scoring systems, and validated measurement tools...
