Meaningful engagement of patients and families in a complex trial of advance care planning in primary care

Engagement of Patient and Family Advisors (PFAs) is increasingly recommended as best practice in research. During the design and conduct of a large trial of advance care planning (ACP) in primary care, we expanded on the funder’s (Patient-Centered Outcomes Research Institute®) requirement for an engagement plan and sought to develop an innovative approach to fostering and sustaining meaningful engagement of PFAs throughout all phases of the trial. Structures were developed that integrated PFAs into planning and provided the foundation for their ongoing participation. A continuous quality improvement approach became the framework for ongoing engagement. This involved setting goals; collecting data through surveys, interviews, and observations; and using data to inform revisions to the engagement approach. We also tracked PFA activities and ideas and documented how they impacted the trial. This article summarizes our experience and describes the challenges we faced and how we addressed them. We also outline key lessons learned about encouraging participation; approaches to preparation and coaching; fostering equity across PFAs and other roles in the trial team; creating a range of opportunities that match PFA skills, preferences, and expectations; the importance of regular feedback; and the need for training of all trial staff. Our experience demonstrates that successful and impactful engagement is possible but requires consistent commitment and intentional dedication of sufficient resources.

Animal origin of 13th-century uterine vellum revealed using noninvasive peptide fingerprinting

The source of this parchment, often called “uterine vellum,” has been a long-standing controversy in codicology. Use of the Latin term abortivum in many sources has led some scholars to suggest that the skin of fetal calves or sheep was used. Others have argued that it would not be possible to sustain herds if so many pocket Bibles were produced from fetal skins, arguing instead for unexpected alternatives, such as rabbit. Here, we report a simple and objective technique using standard conservation treatments to identify the animal origin of parchment. The noninvasive method is a variant on zooarchaeology by mass spectrometry (ZooMS) peptide mass fingerprinting but extracts protein from the parchment surface by using an electrostatic charge generated by gentle rubbing of a PVC eraser on the membrane surface. Using this method, we analyzed 72 pocket Bibles originating in France, England, and Italy and 293 additional parchment samples that bracket this period. We found no evidence for the use of unexpected animals; however, we did identify the use of more than one mammal species in a single manuscript, consistent with the local availability of hides. These results suggest that ultrafine vellum does not necessarily derive from the use of abortive or newborn animals with ultrathin hides, but could equally well reflect a production process that allowed the skins of maturing animals of several species to be rendered into vellum of equal quality and fineness.PostprintPeer reviewe

Academic Community Standards for Chronic Transfusion Therapy in Children with Sickle Cell Anemia and Stroke

Abstract Children with sickle cell anemia have a 5–10% incidence of primary stroke, after which they have a 50–90% risk of stroke recurrence. Monthly transfusions with a goal of maintaining sickle hemoglobin (HbS) 7 days after the scheduled date) occurring once in 22% and twice or more in 12% of children. The average pre-transfusion Hb was 9.0 ± 0.7 gm/dL. The average pre-transfusion %HbS was 35 ± 11 %, with a median %HbS value of 34%. Potential "cutoff " %HbS values for SWiTCH included 34% (50th percentile of reported values), 43% (75th percentile), and 52% HbS (90th percentile). These data indicate that transfusions to prevent recurrent stroke vary among academic pediatric institutions and 30% HbS may not be a realistic goal for this study. Although the goal for transfusions in the SWiTCH standard treatment arm will remain 30% HbS, maintaining an average pre-transfusion HbS value of ≤ 45% will be required to reflect the academic community standard

\u3ci\u3eDrosophila\u3c/i\u3e Muller F Elements Maintain a Distinct Set of Genomic Properties Over 40 Million Years of Evolution

The Muller F element (4.2 Mb, ~80 protein-coding genes) is an unusual autosome of Drosophila melanogaster; it is mostly heterochromatic with a low recombination rate. To investigate how these properties impact the evolution of repeats and genes, we manually improved the sequence and annotated the genes on the D. erecta, D. mojavensis, and D. grimshawi F elements and euchromatic domains from the Muller D element. We find that F elements have greater transposon density (25–50%) than euchromatic reference regions (3–11%). Among the F elements, D. grimshawi has the lowest transposon density (particularly DINE-1: 2% vs. 11–27%). F element genes have larger coding spans, more coding exons, larger introns, and lower codon bias. Comparison of the Effective Number of Codons with the Codon Adaptation Index shows that, in contrast to the other species, codon bias in D. grimshawi F element genes can be attributed primarily to selection instead of mutational biases, suggesting that density and types of transposons affect the degree of local heterochromatin formation. F element genes have lower estimated DNA melting temperatures than D element genes, potentially facilitating transcription through heterochromatin. Most F element genes (~90%) have remained on that element, but the F element has smaller syntenic blocks than genome averages (3.4–3.6 vs. 8.4–8.8 genes per block), indicating greater rates of inversion despite lower rates of recombination. Overall, the F element has maintained characteristics that are distinct from other autosomes in the Drosophila lineage, illuminating the constraints imposed by a heterochromatic milieu

American College of Cardiology; American Heart Association Task Force; European Society of Cardiology Committee for Practice Guidelines. ACC/AHA/ESC 2006 guidelines for management of patients with ventricular arrhythmias and the prevention of sudden cardiac death: a report of the American College of Cardiology/American Heart Association Task Force and the European Society of Cardiology Committee for Practice Guidelines (Writing Committee to Develop Guidelines for Management of Patients With Ventricular Arrhythmias and the Prevention of Sudden Cardiac Death).

The purpose this document is to update and combine the previously published recommendations into one source approved by the major cardiology organizations in the United States and Europe. We have consciously attempted to create a streamlined document, not a textbook, that would be useful specifically to locate recommendations on the evaluation and treatment of patients who have or may be at risk for ventricular arrhythmias. Thus, sections on epidemiology, mechanisms and substrates, and clinical presentations are brief, because there are no recommendations for those sections. For the other sections, the wording has been kept to a minimum, and clinical presentations have been confined to those aspects relevant to forming recommendations
