Question: Question: Are chronic obstructive pulmonary disease patients with psychiatric disorders at greater risk of exacerbations?
Answer: Patients with psychiatric disorders are at greater risk of exacerbations treated in an outpatient setting but not those treated in an inpatient setting. These outpatient-managed exacerbations account for a significant proportion of the healthcare burden for COPD, so interventions should target patients with psychiatric disorders to improve management of COPD.

Answer: yes


Question: Question: Are variants in TNFAIP3 , STAT4 , and C12orf30 loci associated with multiple autoimmune diseases also associated with juvenile idiopathic arthritis?
Answer: We have demonstrated associations between JIA and variants in the TNFAIP3, STAT4, and C12orf30 regions that have previously shown associations with other autoimmune diseases, including RA and systemic lupus erythematosus. Our results suggest that clinically distinct autoimmune phenotypes share common genetic susceptibility factors.

Answer: yes


Question: Question: Does 0.1 % bupivacaine reduce the requirement for epidural fentanyl infusion after major abdominal surgery?
Answer: In low concentrations (0.1%), bupivacaine did not reduce the titrated dose of epidural fentanyl required for adequate pain relief during forced inspiration after major abdominal surgery. The incidence and severity of adverse effects were also comparable whether or not low-dose bupivacaine infusion was used.

Answer:
no
