BACKGROUND: Glioblastoma, the most common adult primary malignant brain tumor, confers poor prognosis (median survival of 15 months) notwithstanding aggressive treatment. Combination chemotherapy including carmustine (BCNU) or temozolomide (TMZ) with the MGMT inhibitor O6-benzylguanine (O6BG) has been used, but has been associated with dose-limiting hematopoietic toxicity. OBJECTIVE: To assess safety and efficacy of a retroviral vector encoding the O6BG-resistant MGMTP140K gene for transduction and autologous transplantation of hematopoietic stem cells (HSCs) in MGMT unmethylated, newly diagnosed glioblastoma patients in an attempt to chemoprotect bone marrowduring combination O6BG/TMZ therapy. METHODS: Three patients have been enrolled in the first cohort. Patients underwent standard radiation therapy without TMZ followed by G-CSF mobilization, apheresis, and conditioning with 600 mg/m2 BCNU prior to infusion of gene-modified cells. Posttransplant, patients were treated with 28-day cycles of single doseTMZ (472 mg/m2) with 48-hour intravenous O6BG (120 mg/m2 bolus, then 30 mg/m2/d). RESULTS: The BCNU dose was nonmyeloablative with ANC ,500/mL for ≤3 d and nadir thrombocytopenia of 28,000/mL. Gene marking in pre-infusion colony forming units (CFUs) was 70.6%, 79.0%, and 74.0% in Patients 1, 2, and 3, respectively, by CFU-PCR. Following engraftment, gene marking in white blood cells and sorted granulocytes ranged between 0.37-0.84 and 0.33-0.83 provirus copies, respectively, by real-time PCR. Posttransplant gene marking in CFUs from CD34-selected cells ranged from 28.5% to 47.4%. Patients have received 4, 3, and 2 cycles of O6BG/TMZ, respectively, with evidence for selection of gene-modified cells. One patient has received a single dose-escalated cycle at 590 mg/m2 TMZ. No additional extra-hematopoietic toxicity has been observed thus far and all three patients exhibit stable disease at 7-8 months since diagnosis CONCLUSIONS: We believe that these data demonstrate the feasibility of achieving significant engraftment of MGMTP140K-modified cells with a well-tolerated dose of BCNU. Further follow-up will determine whether this approach will allow for further dose escalation of TMZ and improved survival.

This study aimed at identifying the best ovitrap installation sites for gravid Aedes aegypti in Mirassol, state of São Paulo, Brazil. Ovitraps were installed in ten houses per block over ten blocks. Four ovitraps were placed per residence, one in the bedroom, one in the living room, and two outdoors with one in a sheltered area and one in an outside site. Each week for eleven weeks, visits were made to examine the ovitraps and to change the paddles used for egg-laying. Eggs were analyzed according to the trap location. The results showed that the outdoor sites received significantly more oviposition than indoor sites. Additionally, in respect to the outdoor sites, the outside site received significantly more oviposition than the sheltered site. A b correlation was observed between positive traps and egg numbers. The results are discussed with respect to the best installation site of the traps and their implications in surveillance and control of dengue vectors.

This third and final report of the CEMACH national diabetes programme comes at an important time in the national drive to improve services for women with diabetes in pregnancy. The National Service Framework (NSF) for Diabetes requires the NHS to develop, implement and monitor policies that seek to empower and support women with diabetes to optimise the outcomes of their pregnancy. The CEMACH report shows that, whilst progress has been made in improving services for women with diabetes and their babies, there is much still to be done to meet the standards recommended by the NSF. Too many women continue to be poorly prepared for pregnancy in the critical areas of glycaemic control and folic acid supplementation. The report underlines the need for an increased focus on diabetes preconception care services and the development of strategies to educate women with diabetes of childbearing age. The growing proportion of women with type 2 diabetes during pregnancy, many of whom are from minority ethnic groups, presents an additional challenge for health services in developing responsive and accessible services.This CEMACH report has identifi ed several areas of good clinical practice during pregnancy in women with pre-existing diabetes. However, there continue to be areas where there is room for improvement, including antenatal fetal surveillance, glycaemic control during labour and delivery and postnatal diabetes care. The National Institute for Health and Clinical Excellence (NICE) is currently in the fi nal stages of development of its new guideline for the management of diabetes in pregnancy. This guideline, when taken together with the CEMACH report, will provide local health services with an unprecedented wealth of material on which to base their development of improved services for women with diabetes in pregnancy.��

A report on the potential to transform disadvantaged communities in Lisburn through early intervention.This feasibility study and consultation was commissioned from Barnardo's with funding from the Public Health Agency, by Resurgam Development Trust representing community and youth organisations in disadvantaged communities in the City of Lisburn, including Old Warren, Hilden, Hillhall, Tonagh, Knockmore and Lagan Valley. It involved consultations with a very wide range of community organisations, schools and professional agencies working in Lisburn. It also included research into: the needs of the target areas; the desired outcomes for children and young people; the evidence and arguments for taking an early intervention approach to the issues; the public policy context and the extent that it might support an early intervention approach; and the evidence of the potential impact of delivering particular proven programmes in the target areas of Lisburn. Researched and written by Dr Roger Courtney.

BACKGROUND: Despite the progress over recent decades in developing community mental health services internationally, many people still receive treatment and care in institutional settings. Those most likely to reside longest in these facilities have the most complex mental health problems and are at most risk of potential abuses of care and exploitation. This study aimed to develop an international, standardised toolkit to assess the quality of care in longer term hospital and community based mental health units, including the degree to which human rights, social inclusion and autonomy are promoted. METHOD: The domains of care included in the toolkit were identified from a systematic literature review, international expert Delphi exercise, and review of care standards in ten European countries. The draft toolkit comprised 154 questions for unit managers. Inter-rater reliability was tested in 202 units across ten countries at different stages of deinstitutionalisation and development of community mental health services. Exploratory factor analysis was used to corroborate the allocation of items to domains. Feedback from those using the toolkit was collected about its usefulness and ease of completion. RESULTS: The toolkit had excellent inter-rater reliability and few items with narrow spread of response. Unit managers found the content highly relevant and were able to complete it in around 90 minutes. Minimal refinement was required and the final version comprised 145 questions assessing seven domains of care. CONCLUSIONS: Triangulation of qualitative and quantitative evidence directed the development of a robust and comprehensive international quality assessment toolkit for units in highly variable socioeconomic and political contexts

L’objectiu d’aquest projecte és analitzar la qualitat literària dels best sellers i observar les limitacions d’aquest anàlisi. Deguda la complexitat del fenòmen best seller, i tot i ser conscients de que són obres que s’han d’abordar des d’una perspectiva pluridisciplinar, vam decidir començar aquest projecte analitzant tres best sellers espanyols des de la metodologia de l’estilística i de la narratologia. Les obres analitzades són 'La sombra del viento' de Carlos Ruiz Zafón, 'Un milagro en equilibrio', de Lucía Etxevarría, i 'El capitán Alatriste', de Pérez Reverte, i l’anàlisi és de tipus quantitatiu, de les estructures emprades per a l’expressió de lo metafòric, dels personatges, trames i tòpics. Les conclusions varen ser que, des d’un punt de vista estilístic, es pot demostrar la mala qualitat literària d’aquestes obres, així com la seva relació amb la tradició del gènere del folletí, amb el que comparteixen moltes característiques. Tanmateix, una altra de les conclusions de l’estudi fou que abordar el best seller des de l’estilística no ofereix una visió completa d’aquest fenòmen. Aquest projecte doncs, que té per títol “Estudio estilístico de tres casos de best seller en el ámbito español: 'La sombra del viento', 'Un milagro en equilibrio' y 'El capitán Alatriste'” ha d’ampliar-se en catàleg i en metodologia, adoptant vàries perspectives simultàneament, que ofereixin una visió adecuada de la complexitat del fenòmen. El catàleg s’ha extès a 15 obres en l’àmbit espanyol, i a 15 més en l’àmbit francès, durant el 2008, i la perspectiva multidisciplinar engloba estudis culturals, de recepció i sociologia. Des d’aquesta nova base metodològica i teòrica, s’han realitzat 500 enquestes a lectors a Barcelona i a París, en diferents punts de venta de llibres, durant el 2010.

BACKGROUND: To improve the efficacy of first-line therapy for advanced non-small cell lung cancer (NSCLC), additional maintenance chemotherapy may be given after initial induction chemotherapy in patients who did not progress during the initial treatment, rather than waiting for disease progression to administer second-line treatment. Maintenance therapy may consist of an agent that either was or was not present in the induction regimen. The antifolate pemetrexed is efficacious in combination with cisplatin for first-line treatment of advanced NSCLC and has shown efficacy as a maintenance agent in studies in which it was not included in the induction regimen. We designed a phase III study to determine if pemetrexed maintenance therapy improves progression-free survival (PFS) and overall survival (OS) after cisplatin/pemetrexed induction therapy in patients with advanced nonsquamous NSCLC. Furthermore, since evidence suggests expression levels of thymidylate synthase, the primary target of pemetrexed, may be associated with responsiveness to pemetrexed, translational research will address whether thymidylate synthase expression correlates with efficacy outcomes of pemetrexed. METHODS/DESIGN: Approximately 900 patients will receive four cycles of induction chemotherapy consisting of pemetrexed (500 mg/m2) and cisplatin (75 mg/m2) on day 1 of a 21-day cycle. Patients with an Eastern Cooperative Oncology Group performance status of 0 or 1 who have not progressed during induction therapy will randomly receive (in a 2:1 ratio) one of two double-blind maintenance regimens: pemetrexed (500 mg/m2 on day 1 of a 21-day cycle) plus best supportive care (BSC) or placebo plus BSC. The primary objective is to compare PFS between treatment arms. Secondary objectives include a fully powered analysis of OS, objective tumor response rate, patient-reported outcomes, resource utilization, and toxicity. Tumor specimens for translational research will be obtained from consenting patients before induction treatment, with a second biopsy performed in eligible patients following the induction phase. DISCUSSION: Although using a drug as maintenance therapy that was not used in the induction regimen exposes patients to an agent with a different mechanism of action, evidence suggests that continued use of an agent present in the induction regimen as maintenance therapy enables the identification of patients most likely to benefit from maintenance treatment.
