The effect of social media (#SoMe) on journal impact factor and parental awareness in paediatric urology.

BACKGROUND: Social media (SoMe) comprises a number of internet-based applications that have the capability to disseminate multimodal media and allow for unprecedented inter-user connectivity. The role of Twitter has been studied in conferences and education; moreover, there is increasing evidence that patients are more likely to use social media for their own health education. OBJECTIVE: The aim of this study was to assess the impact of social media platforms on the impact factor of both urological and paediatric journals that publish on paediatric urology, and to assess parental awareness of social media in paediatric urology. STUDY DESIGN: A filtered Journal of Citation Reports (JCR) search was performed for the period 2012-16 for journals that published articles on paediatric urology. Journals were ranked according to impact factor, and each individual journal website was accessed to assess for the presence of social media. Parents in paediatric urology clinics and non-paediatric urology patients also filled out a questionnaire to assess for awareness and attitudes to social media. All statistical analysis was performed using Prism 6 software (Prism 6, GraphPad Software, California, USA). RESULTS: Overall, there were 50 urological journals and 39 paediatric journals with a mean impact factor of 2.303 and 1.766, respectively. There was an overall average increase in impact factor across all urological journals between 2012 and 16. The presence of a Twitter feed was statistically significant for a rise in impact factor over the 4 years (P = 0.017). The cohort of parents was statistically more likely to have completed post-secondary education, to have and access to a social media profile, use it for health education, and use it to access journal/physician/hospital social media accounts. DISCUSSION: This study examined, for the first time, the role of social media in paediatric urology, and demonstrated that SoMe use is associated with a positive influence in impact factor, but also a parental appetite for it. Limitations included a non-externally validated questionnaire. There may also have been bias in larger journals that generate and maintain social media platforms such as Twitter, which may then in turn have an influence on impact factor. CONCLUSIONS: Social media use within paediatric urology was associated with a higher impact factor, which remained significant after 4 years of analysis. Parents were more likely to use a wide variety of social media to search for conditions and physicians/healthcare providers; therefore, journals and institutions need to embrace and endorse SoMe as a potential source of important clinical information.

The Patterns of Practice and Outcomes of Penile Cancer in Ontario.

AIMS: Penile cancer is a rare malignancy in Western countries. The management guidelines are mainly derived from retrospective studies as there are no randomised trials. The primary objective of this study was to assess patterns of practice and outcomes of penile squamous cell carcinoma in Ontario. Secondary objectives included examining trends in incidence, pathological characteristics and prognostic factors. MATERIALS AND METHODS: All patients diagnosed with penile cancer between 2000 and 2010 were identified from the Ontario Cancer Registry and all available pathology reports related to penile cancer during this period were reviewed. RESULTS: Pathology reports of 419 new cases of penile squamous cell carcinoma were reviewed. There was a significant improvement in completeness of the pathology reports in recent years. The age-adjusted incidence was 0.9 per 100 000 person-years. Most patients presented with a pT1 lesion (63%). A partial penectomy (40%) was the most common surgical procedure. Over 38% of patients identified to be eligible for organ-sparing surgery had a total or partial penectomy. Only 23% of the eligible patients identified to require lymph node dissection underwent the procedure. The 5 year disease-specific survival for stage 0, I, II, III were 94%, 93%, 74% and 52%, respectively. CONCLUSIONS: There is a significant variation in the patterns of practice in Ontario. A large proportion of patients in this cohort were probably overtreated for the primary malignancy and undertreated for the regional nodes.

The JAK3 inhibitor WHI-P154 prevents PDGF-evoked process outgrowth in human neural precursor cells.

The prospect of manipulating endogenous neural stem cells to replace damaged tissue and correct functional deficits offers a novel mechanism for treating a variety of CNS disorders. The aim of this study was to investigate pathways controlling neurite outgrowth in human neural precursor cells, in particular in response to platelet-derived growth factor (PDGF). PDGF-AA, -AB and -BB were found to initiate calcium signalling and produce robust increases in neurite outgrowth. PDGF-induced outgrowth of Tuj1-positive precursors was abolished by the addition of EGTA, suggesting that calcium entry is a critical part of the signalling pathway. Wortmannin and PD098059 failed to inhibit PDGF-induced outgrowth. Clostridium Toxin B increased the amount of PDGF-induced neurite branching but had no effect on basal levels. In contrast, WHI-P154, an inhibitor of Janus protein tyrosine kinase (JAK3), Hck and Syk, prevented PDGF-induced neurite outgrowth. PDGF activates multiple signalling pathways with considerable potential for cross-talk. This study has highlighted the complexity of the pathways leading to neurite outgrowth in human neural precursors, and provided initial evidence to suggest that calcium entry is critical in producing the morphological changes observed.
