Randomised evaluation of the Italian medicines use review provided by community pharmacists using asthma as a model (RE I-MUR)

Background The Italian Ministry of Health decided to introduce community professional services in 2010. This trial provides an opportunity to evaluate the outcomes of a new professional pharmacy service: Italian Medicines Use Review (I-MUR) aimed at reducing the severity of asthma and its associated costs. Methods/Design This is a cluster randomised controlled trial of the I-MUR service. Data will be collected over time before, during and after pharmacists’ intervention. Fifteen Italian regions will be involved and it is aimed to recruit 360 community pharmacists and 1800 patients. Each pharmacist will receive training in medicines use review, recruit five patients, administer the Asthma Control Test and provide the I-MUR service. Pharmacists will be allocated to different groups, one group will be trained in and provide the I-MUR service immediately after completion of the baseline ACT score, the other group will receive training in the I-MUR and provide this service three months later. Group allocation will be random, after stratification by region of Italy. The I-MUR service will involve gathering data following each patient consultation including demographic details, patients regular medications, including those used for asthma, their attitude towards their medications and self-reported adherence to treatments. In addition, pharmacists will identify and record pharmaceutical care issues and any advice given to patients during the I-MUR, or recommendations given to doctors. Pharmacists will upload trial data onto a web platform for analysis. The primary outcome measure is the severity of asthma before, during and after the I-MUR assessed using the Asthma Control Test score. Secondary measures: number of all active ingredients used by patients during and after the I-MUR, number of pharmaceutical care issues identified during the I-MUR, patients’ self-reported adherence to asthma medication during and after the I-MUR, healthcare costs based on the severity of asthma, before, during and after the I-MUR service provision. Discussion This study has been developed because of the need for a new way of working for pharmacists and pharmacies; it is the first trial of any community pharmacy-based pharmaceutical care intervention in Italy. The results will inform future policy and practice in Italian community pharmacy. Trial registration number ISRCTN72438848.

A genome-wide association study of marginal zone lymphoma shows association to the HLA region

Marginal zone lymphoma (MZL) is the third most common subtype of B-cell non-Hodgkin lymphoma. Here we perform a two-stage GWAS of 1,281 MZL cases and 7,127 controls of European ancestry and identify two independent loci near BTNL2 (rs9461741, P=3.95 × 10−15) and HLA-B (rs2922994, P=2.43 × 10−9) in the HLA region significantly associated with MZL risk. This is the first evidence that genetic variation in the major histocompatibility complex influences MZL susceptibility

Regulated gene insertion by steroid-induced ΦC31 integrase

Nonviral integration systems are widely used genetic tools in transgenesis and play increasingly important roles in strategies for therapeutic gene transfer. Methods to efficiently regulate the activity of transposases and site-specific recombinases have important implications for their spatiotemporal regulation in live transgenic animals as well as for studies of their applicability as safe vectors for genetic therapy. In this report, strategies for posttranslational induction of a variety of gene-inserting proteins are investigated. An engineered hormone-binding domain, derived from the human progesterone receptor, hPR891, and specifically recognized by the synthetic steroid mifepristone, is fused to the Sleeping Beauty, Frog Prince, piggyBac and Tol2 transposases as well as to the Flp and ΦC31 recombinases. By analyzing mifepristone-directed inducibility of gene insertion in cultured human cells, efficient posttranslational regulation of the Flp recombinase and the ΦC31 integrase is documented. In addition, fusion of the ΦC31 integrase with the ERT2 modified estrogen receptor hormone-binding domain results in a protein, which is inducible by a factor of 22-fold and retains 75% of the activity of the wild-type protein. These inducible ΦC31 integrase systems are important new tools in transgenesis and in safety studies of the ΦC31 integrase for gene therapy applications

Dynamics and control of a VTOL quad-thrust aerial robot

Some possible useful applications for Vertical Take-Off & Landing (VTOL) Unmanned Aerial Vehicles (UAVs) include remote video surveillance by security personnel, scouting missions or munitions delivery for the military, filming sports events or movies from almost any angle and transporting or controlling equipment. This paper describes the design, control and performance of a low-cost VTOL quadrotor UAV, known as the QTAR (Quad Thrust Aerial Robot)

Treatment of mucosa-associated lymphoid tissue lymphoma of the stomach with radiation alone.

PURPOSE Mucosa-associated lymphoid tissue (MALT) lymphoma of the stomach (MLS) has recently been defined as a distinct clinicopathologic entity, often associated with Helicobacter pylori infection. Many regard antibiotic therapy as the primary treatment of MLS, but in the absence of H pylori infection, or when salvage of antibiotic failures is required, gastrectomy and/or chemotherapy have frequently been used. This study evaluates the efficacy of low-dose radiotherapy alone as an alternative to surgery. PATIENTS AND METHODS Seventeen patients with stage I to II(2) low-grade MLS without evidence of H pylori infection or with persistent lymphoma after antibiotic therapy of associated H pylori infection were included in this series. Median age was 69 years (range, 39 to 84). Median total radiation dose was 30 Gy (range, 28.5 to 43.5 Gy) delivered in 1.5-Gy fractions within 4 weeks to the stomach and adjacent lymph nodes. Following treatment, all patients underwent endoscopic evaluation and biopsy at a median of 4 months, at 6-month intervals to 2 years, and annually thereafter. RESULTS All obtained a biopsy-confirmed complete response. At a median follow-up time of 27 months (range, 11 to 68) from completion of radiotherapy, event-free survival was 100%. Treatment was well tolerated, with no significant acute side effects. All remained asymptomatic at last follow-up. CONCLUSION These results suggest that effective treatment of MLS with low-dose radiation therapy alone is feasible and safe, and allows stomach preservation. Longer follow-up evaluation is required to determine the long-term efficacy of this treatment approach and its side effects. Further studies should clarify the indications for radiotherapy in H pylori-negative or antibiotic-resistant cases of MLS. </jats:sec

EBV-positive lymphoma patients have a selective deficiency in EBV immunity

21032 Background: Epstein-Barr virus (EBV) asymptomatically establishes persistent infections in more than 90% of the adult population. However, due to effective immune control, only a minority of infected carriers develops spontaneous EBV-associated lymphomas. Since EBV nuclear antigen-1 (EBNA1) is the only protein expressed in all proliferating EBV infected cells we hypothesize that EBNA1 specific immune response is critical in preventing EBV-positive lymphomas. Methods: After informed consent, peripheral blood from healthy volunteers and lymphoma patients (prior to therapy- no evidence of cytopenia) were stimulated (ex vivo) with overlapping peptides covering the immunogenic EBNA1 (aa400–641) sequence. Frequency of EBNA1-specific T-cells were assessed by intracellular cytokine staining and flow cytometric proliferation assays. Cytokine pattern, surface marker phenotype and functional reactivity against EBV specific and control antigens were analyzed. Results: Patient and volunteer immune responses to control antigens and other viruses were assessed and statistically indistinguishable. EBNA1 specific CD4+ T cell responses were detected among 18 of 20 healthy carriers, and among 10 of 16 patients with EBV-negative lymphoma (relative to healthy volunteers p=0.145 via paired student T test). None of the patients with EBV-positive lymphomas (n=8) had a detectable EBNA1-specific CD4+ T-cell response (p&lt;0.003 relative to healthy volunteers and patients with EBV-negative lymphomas). Conclusions: Healthy volunteers and patients with EBV-negative lymphoma have statistically similar EBNA1-specific CD4+ T cell responses. Although patients with EBV-positive lymphoma have intact immune responses to common viruses and antigens, they selectively lack an EBNA1-specific CD4+ T cell response. An intact EBNA1 specific immune response among patients with EBV-negaitve lymphoma implies that lymphoma is not a cause of a selective immune deficiency. On the contrary, these findings suggest that EBNA1-specific CD4+ T cells are critical in the prevention of EBV mediated lymphomas, and a defect in EBNA1 specific immunity may leave EBV carriers suseptible to EBV-positive lymphomas. EBNA1- specific CD4+ T cell function may be a new target for therapies of EBV-associated malignancies. No significant financial relationships to disclose. </jats:p
