Dedicated severe asthma services improve healthcare utilisation and quality of life.
Systematic assessment of severe asthma can be used to confirm the diagnosis, identify comorbidities, and address adherence to therapy. However, the prospective usefulness of this approach is yet to be established. The objective of this study was to determine whether the systematic assessment of severe asthma is associated with improved quality of life (QoL) and health-care use and, using prospective data collection, to compare relevant outcomes in patients referred with severe asthma to specialist centers across the United Kingdom. ⋯ To our knowledge, this is the first time that a prospective study has shown that a systematic assessment at a dedicated severe asthma center is associated with improved QoL and asthma control and a reduction in health-care use and oral steroid burden.

Resective Epilepsy Surgery for Tuberous Sclerosis in Children: Determining Predictors of Seizure Outcomes in a Multicenter Retrospective Cohort Study.
There are no established variables that predict the success of curative resective epilepsy surgery in children with tuberous sclerosis complex (TSC). ⋯ In this large consecutive cohort of children with TSC and medically intractable epilepsy, a greater extent of resection (more than just the tuber) is associated with a greater probability of seizure freedom. This suggests that the epileptogenic zone may include the cortex surrounding the presumed offending tuber.

Can 360-Degree Reviews Help Surgeons? Evaluation of Multisource Feedback for Surgeons in a Multi-Institutional Quality Improvement Project.
Medical organizations have increased interest in identifying and improving behaviors that threaten team performance and patient safety. Three hundred and sixty degree evaluations of surgeons were performed at 8 academically affiliated hospitals with a common Code of Excellence. We evaluate participant perceptions and make recommendations for future use. ⋯ Three hundred and sixty degree evaluations can provide a practical, systematic, and subjectively accurate assessment of surgeon performance without undue reviewer burden. The process was found to result in beneficial behavior change, according to surgeons and their coworkers.

Consensus on how best to express bronchodilator reversibility (BDR) is lacking. We tested different BDR criteria against the null hypotheses that BDR should show no sex or size bias. To determine the best criterion for defining BDR, we hypothesized that clinically important BDR should be associated with better survival in respiratory patients compared with that of patients without BDR. ⋯ We have shown that expressing FEV1 BDR as % predicted avoids sex and size bias. FEV1 BDR > 8% predicted showed optimal survival advantage and may be the most appropriate criterion to define clinically important reversibility.

Targeting CD38 with Daratumumab Monotherapy in Multiple Myeloma.
Multiple myeloma cells uniformly overexpress CD38. We studied daratumumab, a CD38-targeting, human IgG1κ monoclonal antibody, in a phase 1-2 trial involving patients with relapsed myeloma or relapsed myeloma that was refractory to two or more prior lines of therapy. ⋯ Daratumumab monotherapy had a favorable safety profile and encouraging efficacy in patients with heavily pretreated and refractory myeloma.
