The CBPJPF aims to assist all seriously injured rugby players through donations made by individuals and organisations, including SA RUGBY. These seriously injured players form the CBPJPF ‘membership’ who often mention their appreciation for this lifeline. However, the founding member of the CBPJPF—Morne Du Plessis—is quick to say ‘we don’t want any new members’.5

- Description: Change-of-direction speed (CODS) is an important quality to performance in multi-direction sports. The purpose of this study was to examine two methods used by basketball players to change directions when playing defense to see if one technique was faster than the other. Within basketball, there are two commonly taught methods of changing directions when playing defense: the drop step and the hip turn. Fourteen female college basketball players participated in this study. The study used a 2×2 (movement x direction) within-subjects repeated measures ANOVA to analyze the average differences between the time to change directions using a drop step compared to a hip turn. There was a significant difference between the two techniques in a novel test, with the hip turn faster than the drop step (F = 117.568, p < .0001). These results suggest that the hip turn compared to the drop step may be a quicker means of changing directions for female basketball players when playing defense.

- Description: Stool samples were collected from 148 healthy adults living a traditional subsistence lifestyle in Papua New Guinea and screened for enteric pathogens using real-time RT-PCR/PCR assays. Enteric pathogens were detected in a high proportion (41%) of individuals. Clear differences were observed in the detection of pathogens between highland and lowland communities. In particular, there was a marked difference in detection rates of norovirus GII (20% and 0%, respectively) and Shigella sp. (15% and 0%, respectively). Analysis of the relationship between enteric pathogen carriage and microbial community composition of participants, using box plots to compare specific normal flora population numbers, did not suggest that gut microbial composition was directly associated with pathogen carriage. This study suggests that enteric pathogens are common in healthy individuals in Papua New Guinean highland communities, presumably acting as a reservoir of infection and thus contributing to a high burden of gastrointestinal illnesses.

- Description: Primary objective: To conduct the first video analysis of concussion in the Australian National Rugby League (NRL) and describe player and injury characteristics, situational factors and time to return to play.Research design: Descriptive, observational case series.Methods and procedures: Video analysis of 20 medically diagnosed concussions for three consenting clubs during the 2013 NRL season.Main outcome and results: Most concussions (83%) occurred during a high tackle, and all injured ball carriers were hit high. Loss of consciousness was observed in 30% of cases. Common observable signs of injury included clutching of the head, balance problems or wobbly legs and a blank or vacant state. There were no post-concussive seizures. All players with loss of consciousness were removed from play. However, only half of the total sample was removed from play and one athlete who was removed returned to play in the same match. Of the players who were removed from play, the large majority returned the following week. Illegal play accounted for 25% of all concussions.Conclusions: Video analysis may be a useful method to study the incidence, mechanism and management of concussion in sports such as Rugby League. Future studies may include larger numbers to validate this preliminary data and may also investigate other levels of play and age ranges. © 2015 Taylor and Francis Group, LLC.

- Description: Background: Higher levels of insomnia predict greater depression severity among older adults; however. The psychological mechanisms underlying this relationship are unclear. This study tested a path model that explored whether dysfunctional beliefs about sleep and hopelessness mediate. The relationship from insomnia to depression. It was hypothesized that insomnia would predict depression, both directly and indirectly, via dysfunctional beliefs about sleep and hopelessness. Methods: A community sample of 218 independent-living Australian older adults aged from 65 to 96 years completed a self-report questionnaire package. From the initial 218 participants, 171 completed a measure of depression three months later. Results: Path analysis demonstrated that maladaptive sleep beliefs and hopelessness partly explained how insomnia influenced depression, irrespective of the presence of obstructive sleep apnea and/or restless legs syndrome. Conclusions: An older adult's beliefs about sleep and sense of hopelessness were important psychological factors that helped explain how insomnia related to depression. © 2013 International Psychogeriatric Association.

- Description: Background Adjunctive psychosocial interventions are efficacious in bipolar disorder, but their incorporation into routine management plans are often confounded by cost and access constraints. We report here a comparative evaluation of two online programs hosted on a single website (www.moodswings.net.au). A basic version, called MoodSwings (MS), contains psychoeducation material and asynchronous discussion boards; and a more interactive program, MoodSwings Plus (MS-Plus), combined the basic psychoeducation material and discussion boards with elements of Cognitive Behavioral Therapy. These programs were evaluated in a head-to-head study design. Method Participants with Bipolar I or II disorder (n=156) were randomized to receive either MoodSwings or MoodSwings-Plus. Outcomes included mood symptoms, the occurrence of relapse, functionality, Locus of Control, social support, quality of life and medication adherence. Results Participants in both groups showed baseline to endpoint reductions in mood symptoms and improvements in functionality, quality of life and medication adherence. The MoodSwings-Plus group showed a greater number of within-group changes on symptoms and functioning in depression and mania, quality of life and social support, across both poles of the illness. MoodSwings-Plus was superior to MoodSwings in improvement on symptoms of mania scores at 12 months (p=0.02) but not on the incidence of recurrence. Limitations The study did not have an attention control group and therefore could not demonstrate efficacy of the two active arms. There was notable (81%) attrition by 12 months from baseline. Conclusion This study suggests that both CBT and psychoeducation delivered online may have utility in the management of bipolar disorder. They are feasible, readily accepted, and associated with improvement. © 2014 Elsevier B.V. All rights reserved.

- Description: Autism Spectrum Disorder (ASD) is a lifelong disability with no known cause or cure. Among the suggested etiologies, is Cannell's hypothesis of a deficiency in Vitamin D the main natural source of which is Solar Ultraviolet-B (UVB) radiation. The aim in this paper is to build on this hypothesis and explore the relationship of solar irradiance of which UVB is a component, by latitude with the prevalence rates of ASD. Twenty-five reports published between 2011 and 2016 using comparable diagnostic criteria were reviewed. The results suggest a tendency for the prevalence rates of ASD to be lowest in countries near the equator and for this rate to increase as the latitude increases. These findings provide some support not just for the Vitamin D hypothesis, but also for a new proposition that along with UVB radiation, the entire solar radiation spectrum which reaches the earth, may play a role in ASD. While these results are both novel and encouraging in terms of the potential efficacy of exposure to natural sunlight, further research is warranted before results can be considered definitive, and before the implications of the findings can be implemented clinically. © 2017 Elsevier Ltd

- Description: Despite the wealth of commercially available antibodies to human proteins, research is often hindered by their inconsistent validation, their poor performance and the inadequate coverage of the proteome. These issues could be addressed by systematic, genome-wide efforts to generate and validate renewable protein binders. We report a multicenter study to assess the potential of hybridoma and phage-display technologies in a coordinated large-scale antibody generation and validation effort. We produced over 1,000 antibodies targeting 20 SH2 domain proteins and evaluated them for potency and specificity by enzyme-linked immunosorbent assay (ELISA), protein microarray and surface plasmon resonance (SPR). We also tested selected antibodies in immunoprecipitation, immunoblotting and immunofluorescence assays. Our results show that high-affinity, high-specificity renewable antibodies generated by different technologies can be produced quickly and efficiently. We believe that this work serves as a foundation and template for future larger-scale studies to create renewable protein binders.

Our review has two main purposes. First, estimate the prevalence of postpartum depressive symptoms in Chinese immigrant women, and then determine risk factors for postpartum depressive symptoms among these women. Methods: The following databases: MEDLINE, Embase, Scopus, Web of Science, PsycINFO and PubMed were used in literature search from their commencements until November 21st 2017. The Joanna Briggs Institute (JBI) Critical Appraisal instruments were used to evaluate the quality of the article. Four studies met the inclusion criteria, contributed to our review and meta-analysis. Result: The prevalence of postpartum depression is high in Chinese immigrant women. Risk factors for postpartum depression in Chinese immigrant women were defined as lack of social support, unstable economic status, and acculturation. Conclusion: There have been few studies on postpartum depression among Chinese immigrant women. Existing studies have shown a high prevalence of postpartum depression in Chinese immigrant women. Moreover, there is an urgent need for studies on postpartum depression among Chinese immigrant women informing better understanding, programs of care and improving the perinatal health status of Chinese immigrant women.

- Description: Background: The definition of health incorporates the physical, social and mental domains, however the Physical Activity (PA) guidelines do not address social health. Furthermore, there is insufficient evidence about the levels or types of PA associated specifically with psychological health. This paper first presents the results of a systematic review of the psychological and social health benefits of participation in sport by adults. Secondly, the information arising from the systematic review has been used to develop a conceptual model of Health through Sport. Methods: A systematic review of 14 electronic databases was conducted in June 2012, and studies published since 1990 were considered for inclusion. Studies that addressed mental and/or social health benefits from participation in sport were included. Results: A total of 3668 publications were initially identified, of which 11 met the selection criteria. There were many different psychological and social health benefits reported, with the most commonly being wellbeing and reduced distress and stress. Sport may be associated with improved psychosocial health in addition to improvements attributable to participation in PA. Specifically, club-based or team-based sport seems to be associated with improved health outcomes compared to individual activities, due to the social nature of the participation. Notwithstanding this, individuals who prefer to participate in sport by themselves can still derive mental health benefits which can enhance the development of true-self-awareness and personal growth which is essential for social health. A conceptual model, Health through Sport, is proposed. The model depicts the relationship between psychological, psychosocial and social health domains, and their positive associations with sport participation, as reported in the literature. However, it is acknowledged that the capacity to determine the existence and direction of causal links between participation and health is limited by the cross-sectional nature of studies to date. Conclusion: It is recommended that participation in sport is advocated as a form of leisure-time PA for adults which can produce a range of health benefits. It is also recommended that the causal link between participation in sport and psycho-social health be further investigated and the conceptual model of Health through Sport tested. © 2013 Eime et al.; licensee BioMed Central Ltd.

- Description: Despite the improved quality of synthetic turf surfaces, players are still expressing their discontent with the perceived greater risk of sustaining abrasion injuries on them relative to natural turf. The validity of the current device, the Securisport®, used to measure the abrasiveness of synthetic turf playing surfaces has been challenged based on its unrealistic interaction with the surface throughout testing. It rotates on the surface at a speed of 40 ± 1 r/min. The aim of this study was to compare the abrasion measurements from the current Securisport device with those from a modified device. The modified device moved across the surface in a linear direction at a speed of 5 m/s, replicating a soccer slide tackle. Data were captured for three trials for each device on three different surfaces: sand-only infill, low-rubber infill and high-rubber infill. Overall, it was found that there was a significant mean abrasion difference of 51.7% between the two devices (p = 0.02) and also significant differences resided between the two devices at specific infill levels. The results of this study found that the specific modifications to the current Securisport device, substantially changed abrasion measurements on synthetic turf, therefore illustrating the need for further work to improve the validity of the Securisport. © IMechE 2015.

- Description: Dietary nitrate supplementation has been shown to increase nitric oxide (NO) metabolites, reduce blood pressure (BP) and enhance exercise performance. Acute exposure to ultraviolet (UV)-A light also increases NO bioavailability and reduces BP. We conducted a randomized, counterbalanced placebo-controlled trial to determine the effects of UV-A light alone and in combination with nitrate on the responses to sub-maximal steady-state exercise and time trial (TT) performance. Nine cyclists (VO2max 53.1 +/- 4.4 ml/kg/min) completed five performance trials comprising 10 min submaximal steady-state cycling followed by a 16.1 km TT. Following a familiarization the final four trials were preceded, in random order, by either (1) Nitrate gels (NIT) + UV-A, (2) Placebo (PLA) + UV-A, (3) NIT + Sham light (SHAM) and (4) PLA + SHAM (control). The NIT gels (2 x 60 ml gels, ~8.1 mmol nitrate) or a low-nitrate PLA were ingested 2.5 h prior to the trial. The light exposure consisted of 20 J/cm(2) whole body irradiation with either UV-A or SHAM light. Plasma nitrite was measured pre- and post-irradiation and VO2 was measured continuously during steady-state exercise. Plasma nitrite was higher for NIT + SHAM (geometric mean (95% CI), 332 (292-377) nM; P = 0.029) and NIT + UV-A (456 (312-666) nM; P = 0.014) compared to PLA + SHAM (215 (167-277) nM). Differences between PLA + SHAM and PLA + UV-A (282 (248-356) nM) were small and non-significant. During steady-state exercise VO2 was reduced following NIT + UVA (P = 0.034) and tended to be lower in NIT + SHAM (P = 0.086) but not PLA + UV-A (P = 0.381) compared to PLA + SHAM. Performance in the TT was significantly faster following NIT + UV-A (mean +/- SD 1447 +/- 41 s P = 0.005; d = 0.47), but not PLA + UV-A (1450 +/- 40 s; d = 0.41) or NIT + SHAM (1455 +/- 47 s; d = 0.28) compared to PLA + SHAM (1469 +/- 52 s). These findings demonstrate that exposure to UV-A light alone does not alter the physiological responses to exercise or improve performance in a laboratory setting. A combination of UV-A and NIT, however, does improve cycling TT performance in this environment, which may be due to a larger increase in NO availability.
