The weekend course Time to be young? gathers young carers, aiming to support them to cope with their challenges in everyday life. The aim of this study was to explore their role as a caregiver and the experienced impact of the course on their strategies of coping in their everyday life.Participants and Methods: The study had a qualitative descriptive design inspired by Lindseth and Norberg’s phenomenological hermeneutical method, using individual semi-structured interviews for data collection. The participants were recruited from former participants of the course Time to be young?, and the final sample included eight participants.Results: Through the analysis, four main themes were identified: 1) Help to accept the situation, 2) A sense of community, 3) The need for information and 4) The need to live one’s own life. The study found that attendance at Time to be young? for young adults having a parent with dementia affected their coping strategies in their situation as a young care.Conclusion: The study demonstrated the importance of courses like Time to be young?, and need for a meeting place, tailored information about dementia, and an opportunity to share and reflect upon their experiences as a young carer.Keywords: dementia, young carers, young adults, course, information

Due to toxicity, not all patients are eligible for this treatment leading to different treatment intensities. Here, we aim to analyze the impact of treatment intensity on survival in patients previously treated with rituximab and chemotherapy, and, furthermore, to analyze the association between socioeconomic position and treatment intensity, defined as palliation, non-salvage, and salvage regimens. Materials and methods: We identified patients with refractory or relapsed DLBCL diagnosed in 2000–2015 in the Danish National Lymphoma Registry (n=1,228). We analyzed the impact of treatment intensity on survival in patients previously treated with rituximab (n=277) using a Cox proportional hazards model. Multinomial regression analyses were performed to identify associations between socioeconomic factors and treatment intensity for the entire cohort. Results: In the rituximab era, the 5-year overall survival (OS) was 31% for patients receiving salvage regimens (n=194), and 17% for patients receiving non-salvage regimens (n=83). In the adjusted analysis, HR was 1.88, 95% CI: 0.9–3.9 for patients receiving salvage regimens. Patients living alone were significantly less likely to receive salvage regimens, as were patients with two or more comorbidities.Conclusion: We observed a better OS in patients treated with salvage regimens compared with non-salvage regimens; however, the adjusted analysis contradicts this. Furthermore, our results indicate that there is a chance of remission for patients not eligible for ASCT.

Mads K Rasmussen, Jakob Nielsen, Rasmus B Kjellerup, Stine M Andersen, Anne H Rittig, Claus Johansen, Lars Iversen, Borbala Gesser Department of Dermatology, Aarhus University Hospital, Aarhus, Denmark Objectives: P90 ribosomal S6 kinase (RSK) 1 and 2 are serine/threonine protein kinases believed to mediate proliferation and apoptosis via the extracellular signal-regulated kinases (ERK1/2) signaling pathway. Macrophage migration inhibitory factor (MIF) and epidermal growth factor (EGF) are activators of this pathway and are elevated in the serum of patients with psoriasis compared with healthy controls. Studies on COS-7 cell cultures have shown that protein phosphatase 2Cδ (PP2Cδ) decreases the activity of RSK2 following EGF stimulation. We therefore hypothesize that PP2Cδ regulates RSK2 activity in psoriasis. Methods: In paired biopsies from nonlesional (NL) and lesional (L) skins, we analyzed the level of RSK1, 2 phosphorylation and the expression of PP2Cδ isoforms, integrin-linked kinase-associated serine/threonine phosphatase (ILKAP) and wild-type p53-induced phosphatase 1 (Wip1) by Western blotting, immunofluorescence and coimmunoprecipitation with monoclonal antibody for RSK2. The induction of Wip1 by MIF or EGF was studied in cultured normal human keratinocytes.Results: The protein level of RSK1, 2 phosphorylated at T573/T577 was significantly increased in L compared with NL psoriatic skin, while phosphorylation at S380/S386 was reduced in L compared with NL psoriatic skin when assayed by Western blotting and immunofluorescence microscopy. ILKAP expression was significantly higher in L than in NL skin, whereas Wip1 was expressed in similar amounts but showed increased coimmunoprecipitation with RSK2 in L compared with NL psoriatic skin. In cultured normal human keratinocytes stimulated with MIF, Wip1 phosphorylation and Wip1 expression were increased after 24 hours, but not when costimulated with dimethyl fumarate (DMF). The increased coimmunoprecipitation of Wip1 with RSK2 was significantly induced by EGF or MIF activation at 24 hours and could be significantly inhibited by DMF or the ERK1/2 inhibitor PD98059. Conclusion: The complex formation of Wip1 with RSK2 indicates a direct interaction reducing P-RSK2 (S386) activation in L skin and indicates that Wip1 has a role in the pathogenesis of psoriasis.

The treatment is mainly considered for younger patients still available for the work market. In this study, social outcomes after ASCT in terms of return to work (RTW) are described.Patients and methods: Information from national administrative registers was combined with clinical information on patients, who received ASCT for relapse of DLBCL or TIL between 2000 and 2012. A total of 164 patients were followed until RTW, disability or old-age pension, death, or December 31, 2015, whichever came first. A total of 205 patients were followed with disability pension as the event of interest. Cox models were used to determine cause-specific hazards. Results: During follow-up, 82 (50%) patients returned to work. The rate of returning to work in the first year following ASCT was decreased for patients being on sick leave at the time of relapse (hazard ratio [HR] 0.3 [0.2;0.5]) and increased for patients aged ≥55 years (HR 1.9 [1.1;3.3]). In all, 56 (27%) patients were granted disability pension. Being on sick leave at the time of relapse was positively associated with receiving a disability pension in the first 2 years after ASCT (HR 3.7 [1.8;7.7]). Conclusion: Patients on sick leave at the time of relapse have a poorer prognosis regarding RTW and have a higher rate of disability pension. Furthermore, patients >55 are more likely to RTW compared to younger patients. These results indicate an unmet need for focused social rehabilitation.
