Making research relevant to policy-makers, development actors, and local communities: NCCR North-South report on effectiveness of research for development

Bridging the gap between research and policy is of growing importance in international development. The National Centre of Competence in Research (NCCR) North-South has rich experience in collaborating beyond academic boundaries to make their research relevant to various societal actors. This publication is the first to provide an overview of the effectiveness of NCCR North-South researchers’ efforts to interact with policy, practice, and local communities with a view to effecting a change in practices. A systematic assessment of researchers’ interactions with non-academic partners is presented, based on principles of monitoring and evaluation. On this basis, tools for collective learning and widespread adaptation are proposed. The report shows with what types of societal actors NCCR North-South researchers collaborate and analyses examples of how researchers conduct dialogue beyond academic boundaries, leading to specific outcomes. It also explains the frame conditions considered decisive for successful and sustainable policy dialogue and concludes with recommendations about how the NCCR North-South can increase the effectiveness of its research for development. The publication is a valuable source of inspiration for those interested in better understanding how to generate the multiple benefits of making science relevant to society.

Cell therapies for heart function recovery: focus on myocardial tissue engineering and nanotechnologies

Cell therapies have gained increasing interest and developed in several approaches related to the treatment of damaged myocardium. The results of multiple clinical trials have already been reported, almost exclusively involving the direct injection of stem cells. It has, however, been postulated that the efficiency of injected cells could possibly be hindered by the mechanical trauma due to the injection and their low survival in the hostile environment. It has indeed been demonstrated that cell mortality due to the injection approaches 90%. Major issues still need to be resolved and bed-to-bench followup is paramount to foster clinical implementations. The tissue engineering approach thus constitutes an attractive alternative since it provides the opportunity to deliver a large number of cells that are already organized in an extracellular matrix. Recent laboratory reports confirmed the interest of this approach and already encouraged a few groups to investigate it in clinical studies. We discuss current knowledge regarding engineered tissue for myocardial repair or replacement and in particular the recent implementation of nanotechnological approaches.

A patient-level pooled analysis assessing the impact of the SYNTAX (synergy between percutaneous coronary intervention with taxus and cardiac surgery) score on 1-year clinical outcomes in 6,508 patients enrolled in contemporary coronary stent trials

This study sought to assess the impact of the SYNTAX (Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery) score (SXscore) on clinical outcomes in patients undergoing percutaneous coronary intervention.

Predictors of Attitudes toward Lesbians and Transgender Women in Relationships on a College Campus

The purpose of this study was to gain a better understanding of the attitudes which perpetuate intolerance toward LGBT individuals, and to recognize, in particular, the unique attitudes transpeople face as a minority in the nation and even in the LGBT community. This research contributes to the bodies of research concerning the interrelatedness of intrinsic religiosity, political conservatism, sexism, the rape myth, lack of effective legal protection, and the intolerance of gender non-conformists. I have identified distinctions between attitudes on the part of both women and men, as well as toward different gender non-conformists. I have also taken research as a whole further by assessing the predictors of attitudes toward specific members of the LGBT community in public relationships. The implications of these findings are potentially as far reaching as to have an impact on policies effecting healthcare, education, anti-discrimination and employer rights legislation, on both local and national levels.

Comparing pneumococcal conjugate vaccine schedules based on 3 and 2 primary doses: systematic review and meta-analysis

Background Pneumococcal conjugate vaccines (PCV) were first licensed for use with 3 primary doses in infancy and a booster dose. The evidence for the effects of different schedules was examined in this systematic review and meta-analysis. Methods We searched 12 databases and trial registers up to March 2010. We selected randomised controlled trials (RCTs), cohort and case–control studies making direct comparisons between PCV schedules with (2p) or (3p) primary doses, with (+1) or without (+0) a booster dose. We extracted data on clinical, nasopharyngeal carriage and immunological outcomes and used meta-analysis to combine results where appropriate. Results Seropositivity levels (antibody concentration ≥0.35 μg/ml) following 3p and 2p PCV schedules were high for most serotypes (5 RCTs). Differences between schedules were generally small and tended to favour 3p schedules, particularly for serotypes 6B and 23F; between-study heterogeneity was high. Seropositivity levels following 3p+1 and 2p+1 schedules were similar but small differences favouring 3p+1 schedules were seen for serotypes 6B and 23F. We did not identify any RCTs reporting clinical outcomes for these comparisons. In 2 RCTs there was weak evidence of a reduction in carriage of S. pneumoniae serotypes included in the vaccine when 3p+0 schedules were compared to 2p+0 at 6 months of age. Conclusions Most data about the relative effects of different PCV schedules relate to immunological outcomes. Both 3p and 2p schedules result in high levels of seropositivity. The clinical relevance of differences in immunological outcomes between schedules is not known. There is an absence of clinical outcome data from RCTs with direct comparisons of any 2p with any 3p PCV schedule.

Bipolar disorder susceptibility region on chromosome 3q29 not confirmed in a case-control association study

We identified a bipolar disorder (BPD) susceptibility region on chromosome 3q29 in a genome-wide linkage scan (Bailer et al. 2002 (Biol Psychiatry 52: 40), NPL-score 4.09) and follow-up linkage analysis (Schosser et al. 2004 (J Psychiatr Res 38(3): 357), NPL-scores >3 with five markers). These findings were supported by further fine-mapping of this region (Schosser et al. 2007 (Eur Neuropsychopharmacol 17(6-7): 501)), finding NPL-scores >3.9 with SNPs (single nucleotide polymorphisms) spanning a region of 3.46 Mbp in BPD families. Since genetic association studies are more powerful than linkage studies for detecting susceptibility genes of small effect size, we aimed to replicate these findings in an independent case-control sample collected in London (UK) and Vienna (Austria).

Impact of testosterone on the expression of organic anion transporting polypeptides (OATP-1A2, OATP-2B1, OATP-3A1) in malignant and non-malignant human breast cells in vitro

Postmenopausal hormone therapy (HT) increases local estrogen formation in breast tissue. The enzymatic substrates depend on transmembrane anion transporting polypeptides (OATPs) to reach intracellular enzymes. The aim of this study was to investigate the effect of testosterone (T) on the expression of OATP-1A2, OATP-2B1, and OATP-3A1 in malignant (MCF-7, BT-474) and non-malignant (HBL-100) breast cells in vitro.

Peer Review Processes for Transdisciplinary Articles: A Reflection on Journal's Practices

Publishing is an essential means of validation and communication of research. This is no different in transdisciplinary research, where publishing also aims at contributing to the development of society through sharing of knowledge. In the scientific world, authors need to disseminate and validate results, reflect on issues, and participate in debates. On the other hand, institutions and individuals are assessed according to their publication record – as probably the most influential of all current evaluation criteria. Occupying the space between article production and counting impact factors, journal editors and reviewers play an important role in defining and using rules to assess and improve the work submitted to them. Publishing transdisciplinary research poses specific challenges, in particular with regard to peer-review processes, as it addresses different knowledge communities with different value systems and purposes.

Influence of Surface Roughness on Mechanical Properties of Two Computer-aided Design/Computer-aided Manufacturing (CAD/CAM) Ceramic Materials

SUMMARY The aim of this study was to evaluate the influence of surface roughness on surface hardness (Vickers; VHN), elastic modulus (EM), and flexural strength (FLS) of two computer-aided design/computer-aided manufacturing (CAD/CAM) ceramic materials. One hundred sixty-two samples of VITABLOCS Mark II (VMII) and 162 samples of IPS Empress CAD (IPS) were ground according to six standardized protocols producing decreasing surface roughnesses (n=27/group): grinding with 1) silicon carbide (SiC) paper #80, 2) SiC paper #120, 3) SiC paper #220, 4) SiC paper #320, 5) SiC paper #500, and 6) SiC paper #1000. Surface roughness (Ra/Rz) was measured with a surface roughness meter, VHN and EM with a hardness indentation device, and FLS with a three-point bending test. To test for a correlation between surface roughness (Ra/Rz) and VHN, EM, or FLS, Spearman rank correlation coefficients were calculated. The decrease in surface roughness led to an increase in VHN from (VMII/IPS; medians) 263.7/256.5 VHN to 646.8/601.5 VHN, an increase in EM from 45.4/41.0 GPa to 66.8/58.4 GPa, and an increase in FLS from 49.5/44.3 MPa to 73.0/97.2 MPa. For both ceramic materials, Spearman rank correlation coefficients showed a strong negative correlation between surface roughness (Ra/Rz) and VHN or EM and a moderate negative correlation between Ra/Rz and FLS. In conclusion, a decrease in surface roughness generally improved the mechanical properties of the CAD/CAM ceramic materials tested. However, FLS was less influenced by surface roughness than expected.

To assess the differential implications of cardiac biomarker type on peri-procedural myocardial infarction (PMI) reporting.

Toxicity of clopidogrel and ticlopidine on human myeloid progenitor cells: importance of metabolites

Ticlopidine and clopidogrel are thienopyridine derivatives used for inhibition of platelet aggregation. Not only hepatotoxicity, but also bone marrow toxicity may limit their use. Aims of the study were to find out whether non-metabolized drug and/or metabolites are responsible for myelotoxicity and whether the inactive clopidogrel metabolite clopidogrel carboxylate contributes to myelotoxicity. We used myeloid progenitor cells isolated from human umbilical cord blood in a colony-forming unit assay to assess cytotoxicity. Degradation of clopidogrel, clopidogrel carboxylate or ticlopidine (studied at 10 and 100 μM) was monitored using LC/MS. Clopidogrel and ticlopidine were both dose-dependently cytotoxic starting at 10 μM. This was not the case for the major clopidogrel metabolite clopidogrel carboxylate. Pre-incubation with recombinant human CYP3A4 not only caused degradation of clopidogrel and ticlopidine, but also increased cytotoxicity. In contrast, clopidogrel carboxylate was not metabolized by recombinant human CYP3A4. Pre-incubation with freshly isolated human granulocytes was not only associated with a myeloperoxidase-dependent degradation of clopidogrel, clopidogrel carboxylate and ticlopidine, but also with dose-dependent cytotoxicity of these compounds starting at 10 μM. In conclusion, both non-metabolized clopidogrel and ticlopidine as well as metabolites of these compounds are toxic towards myeloid progenitor cells. Taking exposure data in humans into account, the myelotoxic element of clopidogrel therapy is likely to be secondary to the formation of metabolites from clopidogrel carboxylate by myeloperoxidase. Concerning ticlopidine, both the parent compound and metabolites formed by myeloperoxidase may be myelotoxic in vivo. The molecular mechanisms of cytotoxicity have to be investigated in further studies.

General Protocol for the Culture of Cells on Plasma-Coated Electrospun Scaffolds

As opposed to culture on standard tissue-treated plastic, cell culture on three-dimensional scaffolds impedes additional challenges with respect to substrate preparation, cell seeding, culture maintenance, and analysis. We herewith present a general route for the culture of primary cells, differentiated cells, or stem cells on plasma-coated, electrospun scaffolds. We describe a method to prepare and fix the scaffolds in culture wells and discuss a convenient method for cell seeding and subsequent analysis by scanning electron microscopy or immunohistology.

Integrated care in patients with schizophrenia: results of trials published between 2011 and 2013 focusing on effectiveness and efficiency

Purpose of review: Overview on integrated care trials focusing on effectiveness and efficiency published from 2011 to 2013. Recent findings: Eight randomized controlled trials (RCTs) and 21 non-RCT studies were published from 2011 to 2013. Studies differed in several methodological aspects such as study population, psychotherapeutic approaches used, outcome parameters, follow-up times, fidelities, and implementation of the integrated care model and the nation-specific healthcare context with different control conditions. This makes it difficult to draw firm conclusions. Most studies demonstrated relevant improvements regarding symptoms (P = 0.001) and functioning (P = 0.01), quality of life (P = 0.01), adherence (P <0.05) and patient's satisfaction (P = 0.01), and reduction of caregiver's stress (P < 0.05). Mean total costs were favoring or at least equalizing costs but with positive effects found on subjective health favoring integrated care models. Summary: There is an increasing interest in the effectiveness and efficiency of integrated care models in patients with mental disorders, specifically in those with severe and persistent mental illness. To increase generalizability, future trials should exactly describe rationales and content of integrated care model and control conditions.
