- BACKGROUND: The Internet should be suitable for delivery of interventions targeting young cancer patients. Young people are familiar with the technologies, and this patient group is small and geographically dispersed. Still, only few psycho-educational Web-based interventions are designed for this group. Young cancer patients consider reproductive health, including sexuality, an area of great importance and approximately 50% report sexual problems and fertility-related concerns following cancer treatment. Therefore, we set out to develop a self-help Web-based intervention, Fex-Can, to alleviate such problems. To improve its quality, we decided to involve patients and significant others as research partners. The first 18 months of our collaboration are described in this paper. The intervention will subsequently be tested in a feasibility study followed by a randomized controlled trial.OBJECTIVE: The study aims to describe the development of a Web-based intervention in long-term collaboration with patient research partners (PRPs).METHODS: Ten former cancer patients and two significant others participated in building the Web-based intervention, using a participatory design. The development process is described according to the design step in the holistic framework presented by van Gemert-Pijnen et al and evaluates the PRPs' impact on the content, system, and service quality of the planned intervention.RESULTS: The collaboration between the research group and the PRPs mainly took place in the form of 1-day meetings to develop the key components of the intervention: educational and behavior change content, multimedia (pictures, video vignettes, and audios), interactive online activities (eg, self-monitoring), and partial feedback support (discussion forum, tailored feedback from experts). The PRPs influenced the intervention's content quality in several ways. By repeated feedback on prototypes, the information became more comprehensive, relevant, and understandable. The PRPs gave suggestions concerning the number of exercises and pointed out texts and pictures needing revision (eg, experienced as normative or stereotypical) to increase the persuasiveness of the program. The system quality was improved by PRPs' feedback on design, technical malfunctions, and navigation on the website. Based on feedback about availability of professional support (technical problems and program content), the organization for support was clarified, which increased service quality. The PRPs also influenced the research project on an overall level by suggesting modifications of inclusion criteria for the RCT and by questioning the implementation plan.CONCLUSIONS: With suggestions and continuous feedback from PRPs, it was possible to develop a Web-based intervention with persuasive design, believed to be relevant and attractive for young persons with cancer who have sexual problems or fertility distress. In the next step, the intervention will be tested in a feasibility study, followed by an RCT to test the intervention's effectiveness in reducing sexual problems and fertility distress.TRIAL REGISTRATION: International Standard Randomized Controlled Trial Number (ISRCTN): 36621459; http://www.isrctn.com/ISRCTN36621459 (Archived by WebCite at http://www.webcitation.org/6gFX40F6T).

- Toll-like receptor 2 (TLR2) expressed on antigen presenting cells evokes a series of critical cytokines, which favor the development of tumor-specific cytotoxic T lymphocytes (CTLs). Therefore, TLR2 represents an attractive cancer immunotherapeutic target. Here, a synthetic library of 14 000 compounds together with a series of newly developed compounds for NF-κB activation using HEK-Blue hTLR2 cells is initially screened. Following further screening in a variety of cells including HEK-Blue hTLRs reporter cells, murine, and human macrophage cell lines, a potent small molecule agonist 23 (SMU-Z1) is identified, which specifically activates TLR2 through its association with TLR1, with a EC50 of 4.88 ± 0.79 × 10-9 m. Toxicology studies, proinflammatory cytokines (e.g., TNF-α, IL-1β, IL-6, and nitric oxide) and target-protein based biophysical assays demonstrate the pharmacologically relevant characteristics of SMU-Z1. In addition, SMU-Z1 promotes murine splenocyte proliferation and upregulates the expression of CD8+ T cells, NK cells and DCs, which results in a significant antitumor effect in a murine leukemia model. Finally, the induced tumors in three out of seven mice disappear after administration of SMU-Z1. Our studies thus identify a novel and potent TLR1/2 small molecule agonist, which displays promising immune adjuvant properties and antitumor immunity.

- OBJECTIVE: 5-alpha reductase inhibitors (5ARIs) decrease the androgen levels in vivo and are currently used for the treatment of benign prostatic hyperplasia (BPH) in men. However, these inhibitors can also increase the risk of gynecomastia, breast tenderness, and breast cancer. Hence, we did a systematic review and meta-analysis to evaluate the rate of breast-related diseases in men treated with 5ARIs.MATERIALS AND METHODS: PubMed, Embase, Cochrane, and CNKI databases were searched for randomized controlled trials using 5ARIs in patients with BPH. Data were analyzed by using Cochrane Collaboration review manager program and Stata 12.0 software.RESULTS: In total, 14 studies were included in the meta-analysis. Gynecomastia was significantly more common with 5ARIs treatment when compared with placebo (3.30% vs. 1.84%; P < .00001) or alpha blockers (ABs) monotherapy (2.33% vs. 1.00%; P = .0009). Both dutasteride (2.03% vs. 0.90%; P < .00001) and finasteride (4.08% vs. 2.43%; P < .00001) are associated with significantly higher risk of gynecomastia than placebo. Risk for breast tenderness was elevated in 5ARIs users (0.83% vs. 0.25%; P = .01) or in users having combination therapy with ABs (2.48% vs. 0.58%; P < .0001). Finasteride is associated with significantly higher risk of breast tenderness than placebo (0.80% vs. 0.25%; P = .02).CONCLUSION: In male patients with BPH, 5ARIs have significantly increased the risk of gynecomastia and breast tenderness but may be not to the breast cancer. In addition, combination therapy is significantly associated with higher risk of breast tenderness compared to single ABs monotherapy. © 2019 Elsevier Inc. All rights reserved.

- Purpose: Improved survival rates of pediatric cancer have drawn attention on how to best facilitate long-term follow up and transition from pediatric to adult care. The transition process is multifactorial and necessitates the joint involvement of the patient, the family and the healthcare providers. The purpose of this study was to explore the experiences of support from healthcare services during the transition from adolescence to adulthood described by young adult survivors of pediatric cancer.Methods: A mixed method with a convergent parallel design was used to evaluate the experiences of receiving support from healthcare services (eg pediatric oncology and pediatric clinic) during transition from adolescence to adulthood described by young adult survivors of pediatric cancer (n = 213) in a nation wide cross-sectional survey.Results: A quantitative assessment of the experienced extent and satisfaction of support from healthcare services to handle physical, mental and social changes to continue life after the disease showed that a majority of the participants had received insufficient support. The qualitative analysis indicated a need for equal roles in healthcare to promote participation, a need to manage and process consequences of the disease, and a need for continuous support.Conclusions: During transition to adulthood, there's a need for a personalized care plan that takes a holistic approach towards supporting the young cancer survivor in managing life in the best way. Identifying and handling the individual needs of pediatric cancer survivors is important for providing the resources and support required to increase the likelihood of successful transition to adulthood. © 2016 Elsevier Ltd.
