Evaluating a childhood obesity program with the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework.

Primary care providers can use behavioral lifestyle interventions to effectively treat children with overweight and obesity, but implementing these interventions is challenging. Most childhood obesity intervention evaluation studies focus on effectiveness. Few studies describe implementation. Our goal was to evaluate critical components of a childhood obesity intervention in primary care. We conducted a pilot implementation study of an existing structured lifestyle intervention in the Canton of Bern, Switzerland from 2013 to 2015. The intervention consisted of 10 sessions, led by a primary care physician. It included children aged 6-8 years old, with BMI over the 90th age-adjusted percentile. We used the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) evaluation framework to describe the pilot implementation study. We stratified description of RE-AIM components at the patient- and physician-level. For Reach: 864 children were screened; 65 were overweight; 394 physicians were invited to participate in the study. For Effectiveness: BMI z-score significantly decreased (-5.6%, p = 0.01). For Adoption: 14 participating physicians treated 26 patients. Implementation: the mean number of consultations was 8. For Maintenance: 9 (35%) children discontinued the intervention; 7 (50%) of physicians continued to apply at least one component of the intervention. The summarized components of the program within the RE-AIM framework suggest the program was successful. Stakeholders can use our results if they intend to disseminate and evaluate similar interventions in different settings

Suspicious axillary lymph nodes in patients with unremarkable imaging of the breast

The aim of this study was to evaluate the pathological findings and the method of tissue harvesting in those patients who have both suspicious axillary lymph nodes and normal imaging of the breast

Crystal Structure of Bicc1 SAM Polymer and Mapping of Interactions between the Ciliopathy-Associated Proteins Bicc1, ANKS3, and ANKS6

Head-to-tail polymers of sterile alpha motifs (SAM) can scaffold large macromolecular complexes. Several SAM-domain proteins that bind each other are mutated in patients with cystic kidneys or laterality defects, including the Ankyrin (ANK) and SAM domain-containing proteins ANKS6 and ANKS3, and the RNA-binding protein Bicc1. To address how their interactions are regulated, we first determined a high-resolution crystal structure of a Bicc1-SAM polymer, revealing a canonical SAM polymer with a high degree of flexibility in the subunit interface orientations. We further mapped interactions between full-length and distinct domains of Bicc1, ANKS3, and ANKS6. Neither ANKS3 nor ANKS6 alone formed macroscopic homopolymers in vivo. However, ANKS3 recruited ANKS6 to Bicc1, and the three proteins together cooperatively generated giant macromolecular complexes. Thus, the giant assemblies are shaped by SAM domains, their flanking sequences, and SAM-independent protein-protein and protein-mRNA interactions
