The Psychological Science Accelerator: Advancing Psychology through a Distributed Collaborative Network

Concerns have been growing about the veracity of psychological research. Many findings in psychological science are based on studies with insufficient statistical power and nonrepresentative samples, or may otherwise be limited to specific, ungeneralizable settings or populations. Crowdsourced research, a type of large-scale collaboration in which one or more research projects are conducted across multiple lab sites, offers a pragmatic solution to these and other current methodological challenges. The Psychological Science Accelerator (PSA) is a distributed network of laboratories designed to enable and support crowdsourced research projects. These projects can focus on novel research questions, or attempt to replicate prior research, in large, diverse samples. The PSA\u27s mission is to accelerate the accumulation of reliable and generalizable evidence in psychological science. Here, we describe the background, structure, principles, procedures, benefits, and challenges of the PSA. In contrast to other crowdsourced research networks, the PSA is ongoing (as opposed to time-limited), efficient (in terms of re-using structures and principles for different projects), decentralized, diverse (in terms of participants and researchers), and inclusive (of proposals, contributions, and other relevant input from anyone inside or outside of the network). The PSA and other approaches to crowdsourced psychological science will advance our understanding of mental processes and behaviors by enabling rigorous research and systematically examining its generalizability

Impact of a program of physiotherapy and health education on the outcome of obstetric fistula surgery

Objective Surgery is the only successful treatment for most obstetric fistulae. The present study measured the impact of a structured program of pre- and postoperative physiotherapy and health education on the outcome of surgery for obstetric fistula. Methods We compared the postoperative outcomes of 2 consecutive groups of women with obstetric fistulae who were recruited and followed-up by 2 local nongovernmental organizations at a hospital in Tanguiéta, Benin. The first group of women (n = 99) had fistula repair using standardized techniques. The second group (n = 112) had a standardized surgical approach plus a structured program of pre- and postoperative health education and physiotherapy. Results The program had a significant positive impact on recovery in general and on urinary incontinence in particular. After physiotherapy, the odds of recovery were 2.72 times greater for women in the physiotherapy group than for control patients, and the probability of postoperative stress incontinence was considerably higher for patients in the control group than for those in the physiotherapy group (P < 0.001). Conclusion A structured program of health education and physiotherapy by experienced nurses and physiotherapists improves the likelihood of a successful outcome after surgical repair of obstetric fistula. © 2013 International Federation of Gynecology and Obstetrics

One-year follow-up of women who participated in a physiotherapy and health education program before and after obstetric fistula surgery

Objective To investigate whether the positive impact of a program of physiotherapy and health education on the outcome of obstetric fistula surgery was maintained after 1 year. Methods The present follow-up analysis included 108 women who underwent obstetric fistula surgery at a center in Tanguiéta, Benin, between March 2011 and March 2012, and who had received a structured program of physiotherapy and health education before and after surgery. After discharge, follow-up visits were made 3, 6, and 12 months after surgery. The Ditrovie scale was used to measure quality of life (QoL), and continence and performance of the physiotherapy exercises were assessed. Results Mean QoL score was 36.9 (range 16.0-49.0) before surgery. Overall, 84 women were followed up for 1 year. Their mean QoL score had improved significantly to 18.5 (range 10.0-47.0; P &lt; 0.001). Between hospital discharge and 1 year, the number of women with a closed fistula increased from 48 (57.1%) to 53 (63.1%) and the number with urinary stress incontinence reduced from 11 (13.1%) to 9 (10.7%). Conclusion Results obtained after surgery and physiotherapy were maintained at 1 year, and QoL had improved significantly. When women are encouraged to continue exercises, improvements are also seen in residual stress incontinence

dnajc2 is required for mouse early embryonic development

International audienceDNAJC2 protein, also known as ZRF1 or MPP11, acts both as chaperone and as chromatin regulator. It is involved in stem cell differentiation and its expression is associated with various cancer malignancies. However, the role of Dnajc2 gene during mouse embryogenesis has not been assessed so far. To this aim, we invalidated Dnajc2 gene in FVB/Nj mice using the CrispR/Cas9 approach. We showed that this invalidation leads to the early post-implantation lethality of the nullizygous embryos. Furthermore, using siRNAs against Dnajc2 in mouse 1-cell embryos, we showed that maternal Dnajc2 mRNAs may allow for the early preimplantation development of these embryos. Altogether, these data demonstrate for the first time the requirement of DNAJC2 for early mouse embryogenesis
