ABSTRACT

In addition to unemployment, poor living and housing conditions and increased morbidity, precarious living situations are often characterized by a lack of or inadequate health insurance. In the Federal Republic of Germany, there is a difficult-to-quantify number of people who, for various reasons, have only limited health insurance coverage or none at all. Those affected include German citizens, EU citizens, and non-EU-citizens who are frequently homeless and/or undocumented. Health care for those groups is predominantly provided outside the German health care system by voluntary non-governmental and welfare organizations. Several German states and municipalities together with non-governmental organizations have addressed this problem by establishing clearing centers often combined with cost reimbursement for medical treatment. In this article, five of these projects are analysed and compared with each other with regard to their structure and mode of operation. The results show that many people can be helped in this way, but in order to meet the high and increasing demand, effort must be put towards more comprehensive solutions as well as on the expansion and sustainability of these projects. At the same time, there is an urgent need to improve statistical and epidemiological data.

ABSTRACT

BACKGROUND: Metastatic breast cancer carries a poor prognosis despite the success of newly targeted therapies. Treatment options remain especially limited for the subtype of triple negative breast cancer (TNBC). Several signaling pathways, including NF-κB, are altered in TNBC, and the complexity of this disease implies multi-faceted pathway interactions. Given that IKKε behaves as an oncogene in breast cancer, we hypothesized that IKKε regulates NF-κB signaling to control diverse oncogenic functions in TNBC. METHODS: Vector expression and RNA interference were used to investigate the functional role of IKKε in triple-negative breast cancer cells. Viability, protein expression, NF-κB binding activity, invasion, anoikis, and spheroid formation were examined in cells expressing high or low levels of IKKε, in conjunction with p52 RNA interference or MEK inhibition. RESULTS: This study found that non-canonical NF-κB p52 levels are inversely proportional to ΙΚΚε, and growth of TNBC cells in anchorage supportive, high-attachment conditions requires IKKε and activated MEK. Growth of these cells in anchorage resistant conditions requires IKKε and activated MEK or p52. In this model, IKKε and MEK cooperate to support overall viability whereas the p52 transcription factor is only required for viability in low attachment conditions, underscoring the contrasting roles of these proteins. CONCLUSIONS: This study illustrates the diverse functions of IKKε in TNBC and highlights the adaptability of NF-κB signaling in maintaining cancer cell survival under different growth conditions. A better understanding of the diversity of NF-κB signaling may ultimately improve the development of novel therapeutic regimens for TNBC.

ABSTRACT

OBJECTIVE: A meeting was convened by the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) and Outcome Measures in Rheumatology (OMERACT) to further the development of consensus among physicians and patients regarding composite disease activity measures and targets in psoriatic arthritis (PsA). METHODS: Prior to the meeting, physicians and patients completed surveys on outcome measures. A consensus meeting of 26 rheumatologists, dermatologists, and patient research partners reviewed evidence on composite measures and potential treatment targets plus results of the surveys. The meeting consisted of plenary presentations, breakout sessions, and group discussions. International experts including members of GRAPPA and OMERACT were invited to the meeting, including the developers of all of the measures discussed. After discussions, participants voted on proposals for use, and consensus was established in a second survey. RESULTS: Survey results from 128 health care professionals and 139 patients were analyzed alongside a systematic literature review summarizing evidence. A weighted vote was cast for composite measures. For randomized controlled trials, the most popular measures were the PsA disease activity score (40 votes) and the GRAPPA composite index (28 votes). For clinical practice, the most popular measures were an average of scores on 3 visual analog scales (45 votes) and the disease activity in PsA score (26 votes). After discussion, there was no consensus on a composite measure. The group agreed that several composite measures could be used and that future studies should allow further validation and comparison. The group unanimously agreed that remission should be the ideal target, with minimal disease activity (MDA)/low disease activity as a feasible alternative. The target should include assessment of musculoskeletal disease, skin disease, and health-related quality of life. The group recommended a treatment target of very low disease activity (VLDA) or MDA. CONCLUSION: Consensus was not reached on a continuous measure of disease activity. In the interim, the group recommended several composites. Consensus was reached on a treatment target of VLDA/MDA. An extensive research agenda was composed and recommends that data on all PsA clinical domains be collected in ongoing studies.

ABSTRACT

Understanding the mechanisms supporting tumor-initiating cells (TIC) is vital to combat advanced-stage recurrent cancers. Here, we show that in advanced ovarian cancers NFκB signaling via the RelB transcription factor supports TIC populations by directly regulating the cancer stem-like associated enzyme aldehyde dehydrogenase (ALDH). Loss of RelB significantly inhibited spheroid formation, ALDH expression and activity, chemoresistance, and tumorigenesis in subcutaneous and intrabursal mouse xenograft models of human ovarian cancer. RelB also affected expression of the ALDH gene ALDH1A2 Interestingly, classical NFκB signaling through the RelA transcription factor was equally important for tumorigenesis in the intrabursal model, but had no effect on ALDH. In this case, classical signaling via RelA was essential for proliferating cells, whereas the alternative signaling pathway was not. Our results show how NFκB sustains diverse cancer phenotypes via distinct classical and alternative signaling pathways, with implications for improved understanding of disease recurrence and therapeutic response.

ABSTRACT

OBJECTIVE: To rank outcomes identified as important to patients with psoriatic arthritis (PsA) and examine their representation in existing composite measures. METHODS: Seven nominal group technique (NGT) meetings took place at 4 hospital sites. Two sorting rounds were conducted to generate a shortlist of outcomes followed by a group discussion and final ranking. In the final ranking round, patients were given 15 points each and asked to rank their top 5 outcomes from the shortlist. The totals were summed across the 7 NGT groups and were presented as a percentage of the maximum possible priority score. RESULTS: Thirty-one patients took part: 16 men and 15 women; the mean age was 54 years (range 24-77; SD 12.2), the mean disease duration was 10.3 years (range 1-40; SD 9.2), and mean Health Assessment Questionnaire was 1.15 (range 0-2.63; SD 0.7). The highest-ranked outcomes that patients wished to see from treatment were pain with 93 points (20.0%), fatigue 62 (13.3%), physical fitness 33 (7.1%), halting/slowing damage 32 (6.9%), and quality of life/well-being 29 (6.2%). Reviewing existing composite measures for PsA demonstrated that no single measure adequately identifies all these outcomes. CONCLUSION: Pain and fatigue were ranked as the outcomes most important to patients receiving treatment for PsA and are not well represented within existing composite measures. Future work will focus on validating composite measures modified to identify outcomes important to patients.

ABSTRACT

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA)-Outcome Measures in Rheumatology (OMERACT) Psoriatic Arthritis (PsA) Core Set working group recently published the updated 2016 psoriatic arthritis (PsA) core domain set, a set of disease features that should be measured in all clinical trials. At the GRAPPA annual meeting in July 2016, the PsA working group presented the updated PsA core domain set endorsed by 90% of participants at OMERACT in May 2016 and drafted a roadmap for the development of the PsA core outcome measurement set. In this manuscript, we review the development process of the PsA core domain set and the ongoing and proposed work streams for development of a PsA core measurement set.

ABSTRACT

Objectives: To determine the effect of medical treatment on work disability in patients with active PsA in a real-world setting. Methods: Four hundred patients with active PsA commencing or switching to anti-TNF or conventional synthetic DMARD (csDMARD) were recruited to a multicentre UK prospective observational cohort study. Work disability was measured using the work productivity and activity-specific health problem instrument and peripheral joint activity was measured with the disease activity in PsA composite measure. Results: Four hundred patients were recruited, of whom 229 (57.25%) were working (of any age). Sixty-two patients of working age (24%) were unemployed. At 6 months there was a 10% improvement in presenteeism ( P = 0.007) and a 15% improvement in work productivity ( P = 0.001) among working patients commenced on csDMARDs ( n = 164) vs a larger and more rapid 30% improvement in presenteeism ( P < 0.001) and 40% improvement in work productivity ( P < 0.001) among those commenced on anti-TNF therapy ( n = 65). Clinical response was poor among patients commenced on a csDMARD ( n = 272), with an 8.4 point improvement in disease activity in PsA ( P < 0.001) vs those commenced on anti-TNF therapy ( n = 121), who had a 36.8 point improvement ( P < 0.001). Conclusion: We report significant and clinically meaningful improvements in both work disability and clinical outcomes after commencement of anti-TNF therapy in a real-world setting. Improvements in all outcomes among those commencing csDMARDs were slower and of a smaller magnitude.

ABSTRACT

BACKGROUND: Topotecan (TPT) is a therapeutic option for women with platinum-resistant or -refractory ovarian cancer. However, the dose-limiting toxicity of TPT is myelosuppression. This led us to seek a combination treatment to augment TPT anti-cancer activity in a cancer-targeted manner. Ovarian serous cancers, a major subtype, show dysregulated DNA repair pathway and often display a high level of CHEK1 (CHK1), a cell cycle regulator and DNA damage sensor. CHEK1 inhibitors are a novel approach to treatment, and have been used as single agents or in combination chemotherapy in many cancers. METHODS: We evaluated the cellular effects of TPT in a panel of high grade serous (HGS) and non-HGS ovarian cancer cells. We then determined IC50s of TPT in the absence and presence of CHEK1 inhibitor, PF477736. Synergism between TPT and PF477736 was calculated based on cellular viability assays. Cytotoxic effect of the combined treatment was compared with apoptotic activities by Caspase3/7 activity assay and Western blotting of cleaved-PARP1 and γH2AX. RESULTS: Non-HGS ovarian cancer cells were generally more sensitive to TPT treatment compared to HGS ovarian cancer cells. When combined with CHEK1 inhibitor, TPT potently and synergistically inhibited the proliferation of HGS ovarian cancer cells. This dramatic synergism in cellular toxicity was consistent with increases in markers of apoptosis. CONCLUSIONS: Our findings suggest that the addition of CHEK1 inhibitor increases the response of ovarian cancer cells to TPT. Furthermore, reduced dosages of both drugs achieved maximal cytotoxic effects by combining TPT with CHEK1 inhibitor. This strategy would potentially minimize side effects of the drugs for extended clinical benefit.

ABSTRACT

Newly formed centrioles in cycling cells undergo a maturation process that is almost two cell cycles long before they become competent to function as microtubule-organizing centers and basal bodies. As a result, each cell contains three generations of centrioles, only one of which is able to form cilia. It is not known how this long and complex process is regulated. We show that controlled Plk1 activity is required for gradual biochemical and structural maturation of the centrioles and timely appendage assembly. Inhibition of Plk1 impeded accumulation of appendage proteins and appendage formation. Unscheduled Plk1 activity, either in cycling or interphase-arrested cells, accelerated centriole maturation and appendage and cilia formation on the nascent centrioles, erasing the age difference between centrioles in one cell. These findings provide a new understanding of how the centriole cycle is regulated and how proper cilia and centrosome numbers are maintained in the cells.

ABSTRACT

For the first time, 8 patients with psoriatic arthritis (PsA) participated as full delegates at the 2013 Annual Meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA). Patients were invited to provide their perspective for different sessions of the conference program. Before the conference, the patient delegates had a separate meeting to familiarize themselves with the conference program and to gain a better understanding of the vision and objectives of GRAPPA. During the conference, the patient group discussed options for increased involvement in research projects. Herein we summarize the presentations on patient participation in research, the experiences of the patient group, and plans to enhance the patient perspective in psoriasis and PsA research.

ABSTRACT

Psoriatic arthritis (PsA) is a heterogeneous inflammatory arthritis with a varied clinical phenotype. There has been considerable international collaboration over recent years to develop and prioritise appropriate disease domains and outcome measures to capture all aspects of this complex disease. It has been recognised that patient-reported measures and physician assessments are complementary and, when used together, allow an improved reflection of disease burden. Taking this concept one step further, the experience in rheumatoid arthritis has demonstrated benefits of incorporating the patient perspective in the development of outcome measures. We report a systematic review demonstrating (1) that there has been little incorporation of the patient perspective in the development of outcome measures and domains in PsA, (2) the proceedings from the preliminary patient involvement in outcome measures for PsA (PIOMPSA) meetings, and (3) a proposed roadmap for improving patient involvement.
