Abstract
INTRODUCTION Prevalence of non-communicable diseases (NCDs) is increasing globally, with the greatest projected increases in low-income and middle-income countries. We sought to quantify the proportion of Cochrane evidence relating to NCDs derived from such countries. METHODS We searched the Cochrane database of systematic reviews for reviews relating to NCDs highlighted in the WHO NCD action plan (cardiovascular, cancers, diabetes and chronic respiratory diseases). We excluded reviews at the protocol stage and those that were repeated or had been withdrawn. For each review, two independent researchers extracted data relating to the country of the corresponding author and the number of trials and participants from countries, using the World Bank classification of gross national income per capita. RESULTS 797 reviews were analysed, with a reported total number of 12 340 trials and 10 937 306 participants. Of the corresponding authors 90% were from high-income countries (41% from the UK). Of the 746 reviews in which at least one trial had met the inclusion criteria, only 55% provided a summary of the country of included trials. Analysis of the 633 reviews in which country of trials could be established revealed that almost 90% of trials and over 80% of participants were from high-income countries. 438 (5%) trials including 1 145 013 (11.7%) participants were undertaken in low-middle income countries. We found that only 13 (0.15%) trials with 982 (0.01%) participants were undertaken in low-income countries. Other than the five Cochrane NCD corresponding authors from South Africa, only one other corresponding author was from Africa (Gambia). DISCUSSION The overwhelming body of evidence for NCDs pertains to high-income countries, with only a small number of review authors based in low-income settings. As a consequence, there is an urgent need for research infrastructure and funding for the undertaking of high-quality trials in this area.

Abstract
OBJECTIVES To determine the feasibility and reliability of an online patient completed Aberdeen Varicose Vein Questionnaire (AVVQ) as a tool to guide specialist referral. METHODS This was a prospective qualitative and quantitative study. One hundred and six patients completed an online questionnaire. Some 43 (40%) completed the AVVQ questionnaire at home and 63 (60%) did it immediately before their appointment. Venous Clinical Severity Score (VCSS) and CEAP grades were assigned by a consultant vascular surgeon. In 11 patients, the questionnaire was repeated at the time of surgery to assess reproducibility and bias. RESULTS The AVVQ correlated with the specialist's VCSS scores (Spearman coefficient 0.795; p < 0.01) and similarly with CEAP grade (P < 0.01, ANOVA test). AVVQ was reproducible with close agreement (Spearman coefficient 0.89; p < 0.01) between both 1st AVVQ score of 21.61 (sd 10.26; range 6.12-40.14) and 2nd AVVQ score of 21.03 (sd 10.50 range 4.51-42.57). Patients' feedback about the online AVVQ was positive. CONCLUSIONS An online questionnaire is acceptable to patients, correlates with clinical findings and using a threshold value could be used by healthcare Commissioners to guide varicose vein referrals.

Abstract
Epithelial-mesenchymal transition (EMT) is an initiating event in tumor cell invasion and metastasis. It has been shown to occur in resistance to a range of cancer therapies, including tamoxifen. MicroRNAs (miRNAs) have been associated with EMT as well as resistance to standard therapies. To investigate the role of miRNAs in the development of resistance to tamoxifen as well as accompanying EMT-like properties, we established a tamoxifen-resistant (TamR) model by continually exposing MCF-7 breast cancer cells to tamoxifen. In addition to the molecular changes known to be involved in acquired tamoxifen resistance, TamR cells displayed mesenchymal features and had increased invasiveness. Genome-wide miRNA microarray analysis revealed that miRNA-375 was among the top downregulated miRNAs in resistant cells. Re-expression of miR-375 was sufficient to sensitize TamR cells to tamoxifen and partly reversed EMT. A combination of mRNA profiling, bioinformatics analysis and experimental validation identified metadherin (MTDH) as a direct target of miR-375. Knockdown of MTDH partially phenocopied the effects of miR-375 on the sensitivity to tamoxifen and the reversal of EMT. We observed an inverse correlation between the expression of miR-375 and its target MTDH in primary breast cancer samples, implying the pathological relevance of targeting. Finally, tamoxifen-treated patients with higher expression of MTDH had a shorter disease-free survival and higher risk of relapse. As most cancer-related deaths occur because of resistance to standard therapies and metastasis, re-expression of miR-375 or targeting MTDH might serve as potential therapeutic approaches for the treatment of TamR breast cancer.

Abstract
There are assumptions that leg length discrepancy (LLD) may cause low back pain by creating pelvis obliquity and lumbar scoliosis. Although individuals with LLD develop compensatory movements in the lower limbs and pelvis during walking, few investigations have attempted to identify kinematic variables of the upper body. This study aims to gain an understanding of how simulated LLD influences three-dimensional motion of the pelvis and spine. Seven male participants were required to walk barefoot at a preferred speed. Three LLD conditions (1, 2, and 3cm) were simulated using modified pieces of high density EVA attached to the right foot. An optoelectronic motion analysis system was used to record kinematic data of the pelvis and spine (lumbar, lower and upper thoracic segments) for each condition. Differences in range of motion and patterns of movement for the pelvis and lumbar spine were minimal between barefoot and LLD conditions. These observations could be attributed to various kinematic compensatory strategies within the lower limbs which require further in-depth investigation.

Abstract
BACKGROUND AND PURPOSE Interleukin-15 (IL-15) is important in the activation and proliferation of lymphocytic cell populations and is implicated in inflammatory disease. We report the characterization of a novel monoclonal antibody DISC0280 which is specific for human IL-15. EXPERIMENTAL APPROACH DISC0280 was characterized in a direct binding assay of IL-15 with IL-15 receptor α (IL-15Rα) and by its ability to alter IL-15 mediated proliferation of a range of cell lines (cytotoxic T lymphocyte line-2, M-07e, KIT225). A pharmacodynamic model injecting male C57/BL6 mice with IL-15 or IL-15/IL-15Rα, with or without DISC0280, and assessing changes in lymphocytic cell populations and serum cytokines was utilized. KEY RESULTS DISC0280 inhibited the binding of IL-15 to IL-15Rα and also potently inhibits IL-15 dependent proliferation of cells expressing IL-15Rα, shared interleukin 2/ interleukin 15 receptor β chain (IL-15Rβ) and common gamma chain (γ(c) ). DISC0280 also inhibited the IL-15 dependent proliferation of M-07e cells that only express IL-15Rβ/γ(c) subunits. Human IL-15 injected into mice caused an increase in NK1.1(+) and CD3(+) cells in the spleen and peripheral blood and these effects were unexpectedly potentiated by giving DISC0280 with human IL-15. This increase in cells caused by DISC0280/IL-15 co-administration was greater than that observed when IL-15 was administered complexed with soluble IL-15Rα. CONCLUSIONS AND IMPLICATIONS The ability of DISC0280 to bind to the IL-15Rα-binding site on IL-15 allows trans-presentation of IL-15 by DISC0280 in vivo, similar to the trans-presentation by soluble IL-15Rα. DISC0280 may be therefore suitable as a clinical substitute for IL-15.
