The role of peer communication in the socialization of adolescents' pain experiences: a qualitative investigation.

BACKGROUND: Recurrent pain is a common complaint among adolescents. Children learn to resolve or cope with pain largely through family dynamics, particularly maternal influences. By adolescence, young people possess an array of pain behaviors, the culmination of multiple opportunities for modeling and reinforcement of attitudes and beliefs about pain. Adolescence is a time of increased autonomy characterized by, among other complex factors, significant increases in peer influence. Although peers are influential in health-risk behavior, little is known how peers impact adolescents' pain experience. The present study explored the role of peers in adolescents' attitudes toward pain, pain behaviors and over-the-counter analgesics. METHODS: Sixty-minute focus groups were conducted with a sample 24 junior high school students from Halifax, Nova Scotia, Canada (11 male: mean age = 13.45 years, range = 12-15 years; 13 female: mean age = 13.31 years, range = 12-15 years). Participants were randomly assigned to one of five same-gender focus groups designed to explore a wide breadth and depth of information. Sessions were run until theoretical data saturation. Textual data, from transcribed audiotapes, were analyzed with the constant comparative method. RESULTS: Peer influences were apparent in how adolescents communicate about pain and how those communications effect pain expression. Overt pain responses to injury were primarily contextual and depended on perceived threats to peer-time and pain severity. Adolescents were intolerant of peers' pain behaviors when the cause was perceived as not severe. These attitudes impacted how adolescents responded to their own pain; males were careful not to express embarrassing pain in front of peers, females felt no restrictions on pain talk or pain expression. Evidence for peer influence on attitudes toward OTC analgesics was apparent in perceptions of over-use and ease of access. Findings are discussed within the context of social information-processing and gender role expectations. CONCLUSION: Little research has addressed how young people experience pain within the context of the psychosocial influences that dominate during adolescence. The findings provide some insight into the role of peer influences via verbal and non-verbal communication, in adolescents' pain experience. This exploratory study is a necessary first step in understanding the socialization of adolescents' pain experiences

Optimizing memory function in temporal lobe epilepsy

PURPOSE: The study aimed to assess whether engagement in a memory training programme and performing internet brain training exercises improve memory function in people with temporal lobe epilepsy (TLE). METHODS: Seventy-seven people with TLE, complaining of memory difficulties, completed the study. Participants ranged in age from 19 to 67 years and 40 had left TLE. Participants were randomised to one of four conditions; Group 1: traditional memory training, Group 2: Lumosity, an on-line cognitive training programme, Group 3: traditional memory training and Lumosity, and Group 4: no training. Memory efficiency and mood were assessed at baseline and three months later. RESULTS: Group analyses indicated improved verbal recall after training (p<0.001) and improved subjective ratings (p<0.007). More participants reported a lessening of the memory burden (p<0.007) after training; differences were significant between Groups 1 and 3 compared to Group 4. Lumosity use was not associated with changes in the memory outcome measures but there was a relationship with depression ratings and the number of memory games played (p<0.01). Conventional memory training, IQ, and post-surgical status were associated with positive memory outcomes. CONCLUSIONS: The study indicates traditional memory rehabilitation techniques can help reduce the burden of memory impairment in TLE. There was no evidence that Lumosity the on-line cognitive training programme had specific advantages. Positive change was not universal and larger studies will be required to explore factors associated with successful outcomes

Medium energy ion scattering (MEIS) study from the five-fold surface of icosahedral Ag-In-Yb quasicrystal

Medium energy ion scattering (MEIS) is employed to characterize the composition and structure of the five-fold surface of the icosahedral Ag42In42Yb16 quasicrystal. The composition of the surface after sputtering is dominated by Ag and In, and when the surface is annealed at temperatures approaching 430°C, Yb is restored at the surface. The composition is that expected from the bulk structure if the surface is formed at bulk planes involving the centre of rhombic triacontahedral clusters, the building blocks of the system. Structural analysis of MEIS results are also consistent with a surface after annealing that is in close agreement with bulk truncation intersecting the cluster centre

Fine sediment reduces vertical migrations of Gammarus pulex (Crustacea: Amphipoda) in response to surface water loss

Surface and subsurface sediments in river ecosystems are recognized as refuges that may promote invertebrate survival during disturbances such as floods and streambed drying. Refuge use is spatiotemporally variable, with environmental factors including substrate composition, in particular the proportion of fine sediment (FS), affecting the ability of organisms to move through interstitial spaces. We conducted a laboratory experiment to examine the effects of FS on the movement of Gammarus pulex Linnaeus (Crustacea: Amphipoda) into subsurface sediments in response to surface water loss. We hypothesized that increasing volumes of FS would impede and ultimately prevent individuals from migrating into the sediments. To test this hypothesis, the proportion of FS (1–2 mm diameter) present within an open gravel matrix (4–16 mm diameter) was varied from 10 to 20% by volume in 2.5% increments. Under control conditions (0% FS), 93% of individuals moved into subsurface sediments as the water level was reduced. The proportion of individuals moving into the subsurface decreased to 74% at 10% FS, and at 20% FS no individuals entered the sediments, supporting our hypothesis. These results demonstrate the importance of reducing FS inputs into river ecosystems and restoring FS-clogged riverbeds, to promote refuge use during increasingly common instream disturbances

Engaging stakeholders in rehabilitation research: a scoping review of strategies used in partnerships and evaluation of impacts

Abstract: Purpose: To describe how stakeholder engagement has been undertaken and evaluated in rehabilitation research. Methods: A scoping review of the scientific literature using five search strategies. Quantitative and qualitative analyses using extracted data. Interpretation of results was iteratively discussed within the team, which included a parent stakeholder. Results: Searches identified 101 candidate papers; 28 were read in full to assess eligibility and 19 were included in the review. People with disabilities and their families were more frequently involved compared to other stakeholders. Stakeholders were often involved in planning and evaluating service delivery. A key issue was identifying stakeholders; strategies used to support their involvement included creating committees, organizing meetings, clarifying roles and offering training. Communication, power sharing and resources influenced how stakeholders could be engaged in the research. Perceived outcomes of stakeholder engagement included the creation of partnerships, facilitating the research process and the application of the results, and empowering stakeholders. Stakeholder engagement outcomes were rarely formally evaluated. Conclusions: There is a great interest in rehabilitation to engage stakeholders in the research process. However, further evidence is needed to identify effective strategies for meaningful stakeholder engagement that leads to more useful research that positively impacts practice. Implications for Rehabilitation Using several strategies to engage various stakeholders throughout the research process is thought to increase the quality of the research and the rehabilitation process by developing proposals and programs responding better to their needs. Engagement strategies need to be better reported and evaluated in the literature. Engagement facilitate uptake of research findings by increasing stakeholders' awareness of the evidence, the resources available and their own ability to act upon a situation. Factors influencing opportunities for stakeholder engagement need to be better understood

High density lipoproteins improve insulin sensitivity in high-fat diet-fed mice by suppressing hepatic inflammation

Obesity-induced liver inflammation can drive insulin resistance. HDL has anti-inflammatory properties, so we hypothesized that low levels of HDL would perpetuate inflammatory responses in the liver and that HDL treatment would suppress liver inflammation and insulin resistance. The aim of this study was to investigate the effects of lipid-free apoAI on hepatic inflammation and insulin resistance in mice. We also investigated apoAI as a component of reconstituted HDLs (rHDLs) in hepatocytes to confirm results we observed in vivo. To test our hypothesis, C57BL/6 mice were fed a high-fat diet (HFD) for 16 weeks and administered either saline or lipid-free apoAI. Injections of lipid-free apoAI twice a week for 2 or 4 weeks with lipid-free apoAI resulted in: i) improved insulin sensitivity associated with decreased systemic and hepatic inflammation; ii) suppression of hepatic mRNA expression for key transcriptional regulators of lipogenic gene expression; and iii) suppression of nuclear factor κB (NF-κB) activation. Human hepatoma HuH-7 cells exposed to rHDLs showed suppressed TNFα-induced NF-κB activation, correlating with decreased NF-κB target gene expression. We conclude that apoAI suppresses liver inflammation in HFD mice and improves insulin resistance via a mechanism that involves a downregulation of NF-κB activation.

Healthcare professionals' perceptions of pain in infants at risk for neurological impairment

BACKGROUND: To determine whether healthcare professionals perceive the pain of infants differently due to their understanding of that infant's level of risk for neurological impairment. METHOD: Neonatal Intensive Care Units (NICU's) at two tertiary pediatric centers. Ninety-five healthcare professionals who practice in the NICU (50 nurses, 19 physicians, 17 respiratory therapists, 9 other) participated. They rated the pain (0–10 scale and 0–6 Faces Pain Scale), distress (0–10), effectiveness of cuddling to relieve pain (0–10) and time to calm without intervention (seconds) for nine video clips of neonates receiving a heel stick. Prior to each rating, they were provided with descriptions that suggested the infant had mild, moderate or severe risk for neurological impairment. Ratings were examined as a function of the level of risk described. RESULTS: Professionals' ratings of pain, distress, and time to calm did not vary significantly with level of risk, but ratings of the effectiveness of cuddling were significantly lower as risk increased [F (2,93) = 4.4, p = .02]. No differences in ratings were found due to participants' age, gender or site of study. Physicians' ratings were significantly lower than nurses' across ratings. CONCLUSION: Professionals provided with visual information regarding an infants' pain during a procedure did not display the belief that infants' level of risk for neurological impairment affected their pain experience. Professionals' estimates of the effectiveness of a nonpharmacological intervention did differ due to level of risk
