We show here that computer game players can build high-quality crystal structures. Introduction of a new feature into the computer game Foldit allows players to build and real-space refine structures into electron density maps. To assess the usefulness of this feature, we held a crystallographic model-building competition between trained crystallographers, undergraduate students, Foldit players and automatic model-building algorithms. After removal of disordered residues, a team of Foldit players achieved the most accurate structure. Analysing the target protein of the competition, YPL067C, uncovered a new family of histidine triad proteins apparently involved in the prevention of amyloid toxicity. From this study, we conclude that crystallographers can utilize crowdsourcing to interpret electron density information and to produce structure solutions of the highest quality.

Purpose: To investigate the feasibility, acceptability, and preliminary efficacy of a 6-session music therapy protocol on self-efficacy, quality of life, and coping skills in adults with sickle cell disease (SCD). Patients and Methods: Using a mixed-methods intervention design, adults with SCD (ages 21-57; mean age 32.33) were randomized (1:1) to either 1) a 6-session music therapy (MT) intervention (n = 12) or 2) waitlist control (WLC) (n = 12) using stratified randomization where factors were age in years (≤30 vs >30), and sex (male, female). All participants completed two weeks of daily electronic pain diary entries and self-efficacy, quality of life, and coping skills measures before and after their assigned study condition to explore preliminary efficacy. MT participants were taught music exercises accessed via smartphone and subsequently interviewed to determine feasibility and acceptability. Results: The enrollment rate was 89%. All study measures were completed, with high rates of electronic pain diary completion at baseline (70%) and 2-week follow-up (66%). Interviews revealed two overall themes related to MT participants' experience: 1) participants learned new self-management skills and 2) MT improved participants' ability to cope with pain. MT participants demonstrated 100% attendance. In preliminary analyses, MT participants demonstrated significant improvements (means ± SD) in self-efficacy (5.42 ± 5.43, p = 0.008, d = 1.20), PROMIS sleep disturbance (−1.49 ± 6.68, p = 0.023, d = −0.99), PROMIS pain interference (−2.10 ± 4.68, p = 0.016, d = −1.06), and ASCQ-Me social functioning impact scores (2.97 ± 6.91, p = 0.018, d = 1.05) compared to WLC participants. Conclusion: Preliminary findings support the feasibility and acceptability of music therapy for home use in adults with SCD. While music therapy may assist adults with SCD in improving self-efficacy and quality of life, subsequent, fully-powered clinical research is needed to determine its efficacy.

Sickle cell disease (SCD) is a group of genetic disorders primarily affecting individuals of African descent. Adults with SCD experience both acute and chronic pain. Data on music preferences, resources, and music-based pain strategies of adults with SCD are needed to tailor future music therapy interventions to the unique needs of adults with SCD. The purpose of this study was to (1) gather descriptive data related to music use in adults with SCD and (2) explore associations between participants’ music use, pain interference, and perceived helpfulness of music for reducing pain. In total, 100 adults with SCD participated in this survey during outpatient clinic visits. Results indicate a population that: (1) faces significant challenges related to pain interference (M = 61.13, SE = 0.76); (2) perceives music as being helpful for managing challenges, including mood (57%), sleep (48%), stress (47%), and pain (37%); (3) purposefully engages in music listening to manage pain (74%); and (4) would be interested in participating in music therapy services in inpatient (88%) and outpatient (81%) settings. Participants selected songs in genres, such as Hip-Hop/Rap and R&B/Soul, that contrast with previously reported characteristics of music for pain management. There was a moderate positive correlation (rs = 0.516, p < .001) between the number of strategies used alongside music and the perceived helpfulness of music for reducing pain. Findings inform the clinical use of music therapy and support future music therapy research with this population to address quality of life.
