Requirements for a successful Enhanced Recovery After Surgery (ERAS) program: a multicenter international survey among ERAS nurses

Introduction Nurses are the linchpin of any Enhanced Recovery After Surgery (ERAS) program, as they are in direct contact with patients and various caregivers. The aim of the present survey was to assess ERAS key factors and challenges from a nurse's perspective. Methods A qualitative study among ERAS dedicated nurses and ERAS Interactive Audit System (EIAS) administrators using an online questionnaire (Survey Monkey (R), Palo Alto, CA, United States) comprising 29 questions. The survey focused on challenges and drawbacks encountered during ERAS training, implementation and daily clinical practice. Closed multiple-choice and open-end questions and semantic differential scales (0-10) were used. Those invited to participate received three reminders within 4 and 8 weeks after invitation. Results Of 306 nurses invited, 123 completed the survey (response rate 40%). Overall, the success of the institutional ERAS program was rated as 6.9 +/- 2/10. Improving both patient outcomes (90%) and satisfaction (69%) were rated as main motivators for ERAS implementation, while time restraints (50%) and logistics (43%) were identified as the main barriers. The study revealed a wide heterogeneity in coordination and management strategies (ERAS meetings, work models, teaching strategies). Sustained staff education before (9.1/10) and after (9.1/10) implementation, a dedicated ERAS coordinator (8.9/10) and regular meetings (8.3/10 scale) were rated as key factors for a successful program. Difficulty of implementation, maintenance and data acquisition were all rated > 5/10. Conclusion Despite heterogeneity in coordination and management, the ERAS program is evaluated as successful from a nurse's perspective. Continuous staff education and coordination beyond the implementation period appear to be of the utmost importance for a sustained program

Chromosomal contacts connect loci associated with autism, BMI and head circumference phenotypes

Copy number variants (CNVs) are major contributors to genomic imbalance disorders. Phenotyping of 137 unrelated deletion and reciprocal duplication carriers of the distal 16p11.2 220 kb BP2-BP3 interval showed that these rearrangements are associated with autism spectrum disorders and mirror phenotypes of obesity/underweight and macrocephaly/microcephaly. Such phenotypes were previously associated with rearrangements of the non-overlapping proximal 16p11.2 600 kb BP4-BP5 interval. These two CNV-prone regions at 16p11.2 are reciprocally engaged in complex chromatin looping, as successfully confirmed by 4C-seq, fluorescence in situ hybridization and Hi-C, as well as coordinated expression and regulation of encompassed genes. We observed that genes differentially expressed in 16p11.2 BP4-BP5 CNV carriers are concomitantly modified in their chromatin interactions, suggesting that disruption of chromatin interplays could participate in the observed phenotypes. We also identified cis- and trans-acting chromatin contacts to other genomic regions previously associated with analogous phenotypes. For example, we uncovered that individuals with reciprocal rearrangements of the trans-contacted 2p15 locus similarly display mirror phenotypes on head circumference and weight. Our results indicate that chromosomal contacts’ maps could uncover functionally and clinically related genes
