The effect of caffeine ingestion on perception of muscle pain during a sustained submaximal isometric contraction of the quadriceps
Background: The purpose of this study was to determine the effects of an acute dose of 5 mg/kg of caffeine on perceived pain of the quadriceps during a sustained submaximal isometric contraction.
Methods: A total of 15 low caffeine consuming college aged women (20.5 ± 1.4 y, 66.0 ± 9.0 kg; mean ± SD) participated in this study. 2–7 d after a familiarization trial subjects ingested, in a double blind random crossover manner, either 5 mg/kg caffeine (Caf) or a placebo (P), 1 h prior to performing a 2 min isometric leg extension at 45% of peak torque using visual cues to maintain force production. Every 15 s subjects rated their level of pain using the Borg CR10 pain scale. Subjects returned to the lab 2–7 d later to repeat the testing with the other condition. Data were analyzed using a repeated measures ANOVA with a Tukey\u27s HSD post hoc.
Results: Caffeine ingestion resulted in a lower pain score at all time points during the 2 min isometric contraction. This difference approached significance at 90 s (Caf = 3.2 ± 1.4, P = 4.1 ± 1.4; p \u3c 0.10), and became significantly different at 105 s (Caf = 3.8 ± 1.2, P = 4.9 ± 1.5; p \u3c 0.05) and at 120 s (Caf = 4.4 ± 1.5, P = 5.4 ± 1.5; p \u3c 0.05).
Conclusion: Acute caffeine ingestion attenuates perception of muscle pain in the quadriceps during a sustained submaximal isometric contraction. This effect become
Ordinary memory processes in the design of referring expressions
How do speakers produce referential descriptions that satisfy addressees’ informational needs during real-time conversation? A recent proposal is that ordinary memory processes can serve as a proxy for the consideration of common ground. But this is only possible if speakers encode and access sufficiently detailed memory representations. We tested this proposal by having speakers describe referents in contexts varying in perceptual similarity to previous contexts in the dialogue. Based on the analysis of a total of 4,817 descriptions from 112 speakers over three experiments, we found little evidence that contextual similarity modulated the informational content of speakers’ descriptions, regardless of whether that similarity was based on configurational cues (Exps. 1 and 2), or on the perceptual experience of interacting with a conversational partner (Exp. 3). In contrast, speakers did modulate their descriptions when their beliefs about the addressee changed, even when the perceptual match between encoding and retrieval contexts was identical. This suggests that the episodic representations accessed during message generation may be too impoverished to serve as an effective proxy for common ground

Rehabilitation and reintegration programming adjunct to female genital fistula surgery: A systematic scoping review.
Female genital fistula is associated with significant physical, psychological, and economic consequences; however, a knowledge and practice gap exists around services adjunct to fistula surgery.To examine rehabilitation and reintegration services provided adjunct to genital fistula surgery, map existing programming and outcomes, and identify areas for additional research.We searched the published and grey literature from January 2000 to June 2019. Two reviewers screened articles and extracted data using standardized methods.Research and programmatic articles describing service provision in addition to female genital fistula surgery were included.Of 3047 published articles and 2623 unpublished documents identified, 26 and 55, respectively, were analyzed.Programming identified included combinations of health education, physical therapy, social support, psychosocial counseling, and economic empowerment, largely in sub-Saharan Africa. Improvements were noted in physical and psychosocial health.Existing literature supports holistic fistula care through adjunct reintegration programming. Improving the evidence base requires implementing robust study designs, increasing reporting detail, and standardizing outcomes across studies. Increased financing for holistic fistula care is critical for developing and supporting programming to ensure positive outcomes

Rehabilitation and reintegration programming adjunct to female genital fistula surgery: a scoping review protocol
Introduction Female genital fistula is a debilitating traumatic injury, largely birth-associated, globally affecting up to 2 million women, mostly in sub-Saharan Africa. Fistula has significant physical, psychological and economic consequences. Women often face challenges in reintegrating and resuming prior roles despite successful surgery. Synthesising the evidence on services adjunct to fistula surgery and their outcomes is important for developing the evidence base for best practices and identifying research priorities. This scoping review seeks to examine the range of rehabilitation and reintegration services provided as adjunct to genital fistula surgery, map the existing programming and outcomes, and identify areas for additional research.Methods and analysis Our scoping review is informed by existing methodological frameworks and will be conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses-ScR guidelines. The search strategy will be applied to nine biomedical, public health and social science databases. The initial search was completed on 27 September 2018. Grey literature will be identified through targeted Google searches and from organisational websites identified as relevant by the United Nations Population Fund (UNFPA) Campaign to End Fistula. We will iteratively build our search strategy through term harvesting and review, and search reference lists of reports and articles to identify additional studies. Two reviewers will independently screen titles and abstracts, followed by full-text screening of all potentially relevant articles and standardised data extraction. Articles eligible for inclusion will discuss research or programmatic efforts around service provision in adjunct to surgery among females with genital fistula. Data will be presented in summary tables accompanied by narrative description.Ethics and dissemination Ethics approval is not required for a scoping review. Our results can be used to inform policy, serve as support for funding and development of reintegration programmes and highlight areas for subsequent research. Results will be disseminated at relevant conferences and published in a peer-reviewed journal
