Some methodological reflections about the study of religions on video sharing websites

This article offers an overview of methodological difficulties that arise in the study of religions on video sharing websites (VSW). We suggest how to put these difficulties in perspective and how to overcome them. A typology lists the various forms of religions represented on this type of website. We will also try to understand why some religious groups have created their own video sharing websites. Finally we will give possible interpretations of this phenomenon and suggest some ways to use this type of material in academic research and teaching about religions. Cet article propose une vue d'ensemble des difficultés méthodologiques rencontrées dans l'étude des religions sur les sites web de partage de vidéos. Il propose des pistes pour relativiser et surmonter ces difficultés. Une typologie présente les différentes formes sous lesquelles on trouve des religions dans ce type de sites web. Nous tentons aussi de comprendre pourquoi certains groupes religieux ont créé leurs propres sites de partages de vidéos. Enfin, nous donnerons des possibles interprétations du phénomène et suggérerons comment on pourrait utiliser de ce type de matériel dans la recherche et l'enseignement académiques sur les religions.

Validation of the post-delivery perceived stress inventory

This article presents the post-delivery perceived stress inventory (PDPSI) and its psychometric properties. This inventory is unique in that it links the measurement of perceived stress to events experienced during and after delivery. A total of 235 French-speaking, primiparous mothers completed the PDPSI two days after their delivery. To evaluate the predictive validity of the PDPSI on anxiety and depression, participants also completed the EPDS and the STAI two days and six weeks postpartum. The exploratory analysis revealed a 16-item structure divided into five factors: F1: relationship with the child; F2: delivery; F3: fatigue after delivery; F4: breastfeeding; and F5: relationship with the caregivers. The PDPSI demonstrated good internal consistency. Moreover, confirmatory factor analysis produced excellent indices, indicating that the complexity of the PDPSI was taken into account and its fit to the sample. The discriminant analysis showed that the PDPSI was not sensitive to specific changes in the sample making the inventory generalizable to other populations. Predictive validity showed that the scale significantly predicted depression and anxiety in the early postpartum period as well as anxiety six weeks postpartum. Overall, the PDPSI showed excellent psychometric qualities, making it a useful tool for future research-evaluating interventions related to perceived stress during the postpartum period.

Photodynamic drug delivery enhancement in tumours does not depend on leukocyte-endothelial interaction in a human mesothelioma xenograft model.

OBJECTIVES: The pre-treatment of tumour neovessels by low-level photodynamic therapy (PDT) improves the distribution of concomitantly administered systemic chemotherapy. The mechanism by which PDT permeabilizes the tumour vessel wall is only partially known. We have recently shown that leukocyte-endothelial cell interaction is essential for photodynamic drug delivery to normal tissue. The present study investigates whether PDT enhances drug delivery in malignant mesothelioma and whether it involves comparable mechanisms of actions. METHODS: Human mesothelioma xenografts (H-meso-1) were grown in the dorsal skinfold chambers of 28 nude mice. By intravital microscopy, the rolling and recruitment of leukocytes were assessed in tumour vessels following PDT (Visudyne(®) 400 μg/kg, fluence rate 200 mW/cm(2) and fluence 60 J/cm(2)) using intravital microscopy. Likewise, the distribution of fluorescently labelled macromolecular dextran (FITC-dextran, MW 2000 kDa) was determined after PDT. Study groups included no PDT, PDT, PDT plus a functionally blocking anti-pan-selectin antibody cocktail and PDT plus isotype control antibody. RESULTS: PDT significantly enhanced the extravascular accumulation of FITC-dextran in mesothelioma xenografts, but not in normal tissue. PDT significantly increased leukocyte-endothelial cell interaction in tumour. While PDT-induced leukocyte recruitment was significantly blunted by the anti-pan-selectin antibodies in the tumour xenograft, this manipulation did not affect the PDT-induced extravasation of FITC-dextran. CONCLUSIONS: Low-level PDT pre-treatment selectively enhances the uptake of systemically circulating macromolecular drugs in malignant mesothelioma, but not in normal tissue. Leukocyte-endothelial cell interaction is not required for PDT-induced drug delivery to malignant mesothelioma.

Effect of epinephrine on oxygen consumption and delivery during progressive hemorrhage.

OBJECTIVE: To determine whether, during hemorrhagic shock, the effect of epinephrine on energy metabolism could be deleterious, by enhancing the oxygen requirement at a given level of oxygen delivery (DO2). DESIGN: Prospective, randomized, control trial. SETTING: Experimental laboratory. SUBJECTS: Two groups of seven mongrel dogs were studied. The epinephrine group received a continuous infusion of epinephrine (1 microgram/min/kg) while the control group received saline. INTERVENTION: Dogs were anesthetized with pentobarbital, and shock was produced by stepwise hemorrhage. MEASUREMENTS AND MAIN RESULTS: Oxygen consumption (VO2) was continuously measured by the gas exchange technique, while DO2 was independently calculated from cardiac output (measured by thermodilution) and blood oxygen content. A dual-lines regression fit was applied to the DO2 vs. VO2 plot. The intersection of the two regression lines defined the critical value of DO2. Values above critical DO2 belonged to phase 1, while phase 2 occurred below critical DO2. In the control group, VO2 was independent of DO2 during phase 1; VO2 was dependent on DO2 during phase 2. In the epinephrine group, the expected increase in VO2 (+19%) and DO2 (+50%) occurred under normovolemic conditions. During hemorrhage, VO2 immediately decreased, and the slope of phase 1 was significantly (p < .01) different from zero, and was significantly (p < .05) steeper than in the control group (0.025 +/- 0.005 vs. 0.005 +/- 0.010). However, the critical DO2 (8.7 +/- 1.7 vs. 9.7 +/- 2.4 mL/min/kg), the critical VO2 (5.6 +/- 0.5 vs. 5.5 +/- 0.9 mL/min/kg), and the slope of phase 2 (0.487 +/- 0.080 vs. 0.441 +/- 0.130) were not different from control values. CONCLUSIONS: The administration of pharmacologic doses of epinephrine significantly increased VO2 under normovolemic conditions due to the epinephrine-induced thermogenic effect. This effect progressively decreased during hemorrhage. The critical DO2 and the relationship between DO2 and VO2 in the supply-dependent phase of shock were unaffected by epinephrine infusion. These results suggest that during hemorrhagic shock, epinephrine administration did not exert a detrimental effect on the relationship between DO2 and VO2.

Optimization of the piggyBac Transposon Using mRNA and Insulators: Toward a More Reliable Gene Delivery System.

Integrating and expressing stably a transgene into the cellular genome remain major challenges for gene-based therapies and for bioproduction purposes. While transposon vectors mediate efficient transgene integration, expression may be limited by epigenetic silencing, and persistent transposase expression may mediate multiple transposition cycles. Here, we evaluated the delivery of the piggyBac transposase messenger RNA combined with genetically insulated transposons to isolate the transgene from neighboring regulatory elements and stabilize expression. A comparison of piggyBac transposase expression from messenger RNA and DNA vectors was carried out in terms of expression levels, transposition efficiency, transgene expression and genotoxic effects, in order to calibrate and secure the transposition-based delivery system. Messenger RNA reduced the persistence of the transposase to a narrow window, thus decreasing side effects such as superfluous genomic DNA cleavage. Both the CTF/NF1 and the D4Z4 insulators were found to mediate more efficient expression from a few transposition events. We conclude that the use of engineered piggyBac transposase mRNA and insulated transposons offer promising ways of improving the quality of the integration process and sustaining the expression of transposon vectors.

Neurological conditions: involvement to improve service delivery

A major, ongoing Public Health Agency led consultation exercise has identified 12 recommendations to improve the lives of the 48,000 people, and their carers, who experience neurological conditions across Northern Ireland. These recommendations will form the basis of an action plan to improve service delivery and support for those experiencing a range of conditions, such as epilepsy, Huntington's Disease, Parkinson's Disease, progressive supranuclear palsy (PSP) and multiple sclerosis (MS).The recommendations cover four areas:accurate information and diagnosis;control and choice, particularly self-management and person-centred services;day-to-day living and independence, including finance, employment, social life and ability to get out and about;emotional and psychological impact on individuals and families, eg the support available to deal with stress, fear, frustration, isolation, loss and vulnerability associated with living with a neurological condition.The report was launched at a regional workshop, held in Cookstown (today) and co-ordinated through the Neurological Conditions Network, which was established to develop this work.Speaking before the workshop, Health Minister Edwin Poots said: "Neurological conditions give rise to complex needs, which require support from a wide range of professionals. They also change lives, both for those directly affected and for their families and carers, and it is so important not to lose sight of this if we are to successfully address the challenges in tackling neurological conditions."Last week, I visited the home of Beth McCune, who suffers from motor neurone disease. I was invited to see for myself the daily challenges faced by Beth and her husband and carer, Arthur, and to hear of their experiences. While I was struck by their courage and patience, this visit underlined again for me the severe life-changing impact of the disease."At present, there are some 48,000 people in Northern Ireland living with neurological conditions. It was in recognition of the needs of men and women like Beth that my department requested the establishment of the Neurological Conditions Network and provided the necessary funding to support it."Michelle Tennyson, PHA Assistant Director and Chair of the Neurological Conditions Network, said: "This detailed engagement exercise was undertaken to get the views and quality of life experiences of those affected by these conditions. We tried to ensure everyone who wanted to contribute could, by providing support through helplines, the internet and face-to-face events. I am honoured that so many people have trusted us with their experiences to help us make a difference and was privileged to be invited into the home of Beth and Arthur McCune for the same reason."The recommendations cover a range of conditions and their implementation will need cooperation and action from professionals, service users, voluntary organizations and others, across many sectors and agencies. The network is looking forward to delivering on these challenging new ways of working to improve the lives of all those affected by neurological conditions."The workshop attracted service users and carers along with delegates from across Northern Ireland's community, voluntary and statutory sectors.If you have a neurological condition, or care for someone who does, and want to share your experiences, please go to: www.publichealth.hscni.net/ncnsurveyYou can also contact Julie Mawhinney, Tel: 028 9032 1313.

Chronic delivery of antibody fragments using immunoisolated cell implants as a passive vaccination tool.

BACKGROUND: Monoclonal antibodies and antibody fragments are powerful biotherapeutics for various debilitating diseases. However, high production costs, functional limitations such as inadequate pharmacokinetics and tissue accessibility are the current principal disadvantages for broadening their use in clinic. METHODOLOGY AND PRINCIPAL FINDINGS: We report a novel method for the long-term delivery of antibody fragments. We designed an allogenous immunoisolated implant consisting of polymer encapsulated myoblasts engineered to chronically release scFv antibodies targeted against the N-terminus of the Aβ peptide. Following a 6-month intracerebral therapy we observed a significant reduction of the production and aggregation of the Aβ peptide in the APP23 transgenic mouse model of Alzheimer's disease. In addition, functional assessment showed prevention of behavioral deficits related to anxiety and memory traits. CONCLUSIONS AND SIGNIFICANCE: The chronic local release of antibodies using immunoisolated polymer cell implants represents an alternative passive vaccination strategy in Alzheimer's disease. This novel technique could potentially benefit other diseases presently treated by local and systemic antibody administration.

Loss to follow-up of HIV-infected women after delivery : The Swiss HIV Cohort Study and the Swiss Mother and Child HIV Cohort Study

INTRODUCTION: HIV-infected pregnant women are very likely to engage in HIV medical care to prevent transmission of HIV to their newborn. After delivery, however, childcare and competing commitments might lead to disengagement from HIV care. The aim of this study was to quantify loss to follow-up (LTFU) from HIV care after delivery and to identify risk factors for LTFU. METHODS: We used data on 719 pregnancies within the Swiss HIV Cohort Study from 1996 to 2012 and with information on follow-up visits available. Two LTFU events were defined: no clinical visit for >180 days and no visit for >360 days in the year after delivery. Logistic regression analysis was used to identify risk factors for a LTFU event after delivery. RESULTS: Median maternal age at delivery was 32 years (IQR 28-36), 357 (49%) women were black, 280 (39%) white, 56 (8%) Asian and 4% other ethnicities. One hundred and seven (15%) women reported any history of IDU. The majority (524, 73%) of women received their HIV diagnosis before pregnancy, most of those (413, 79%) had lived with diagnosed HIV longer than three years and two-thirds (342, 65%) were already on antiretroviral therapy (ART) at time of conception. Of the 181 women diagnosed during pregnancy by a screening test, 80 (44%) were diagnosed in the first trimester, 67 (37%) in the second and 34 (19%) in the third trimester. Of 357 (69%) women who had been seen in HIV medical care during three months before conception, 93% achieved an undetectable HIV viral load (VL) at delivery. Of 62 (12%) women with the last medical visit more than six months before conception, only 72% achieved an undetectable VL (p=0.001). Overall, 247 (34%) women were LTFU over 180 days in the year after delivery and 86 (12%) women were LTFU over 360 days with 43 (50%) of those women returning. Being LTFU for 180 days was significantly associated with history of intravenous drug use (aOR 1.73, 95% CI 1.09-2.77, p=0.021) and not achieving an undetectable VL at delivery (aOR 1.79, 95% CI 1.03-3.11, p=0.040) after adjusting for maternal age, ethnicity, time of HIV diagnosis and being on ART at conception. CONCLUSIONS: Women with a history of IDU and women with a detectable VL at delivery were more likely to be LTFU after delivery. This is of concern regarding their own health, as well as risk for sexual partners and subsequent pregnancies. Further strategies should be developed to enhance retention in medical care beyond pregnancy.

Cognitive behavioural skills for practice a model for delivery in the Irish mental health service.

This publication outlines a model of delivery for introductory level Cognitive Behavioural Therapy (CBT) training in the Mental Health Service, HSE South (Carlow, Kilkenny, South Tipperary, Waterford, Wexford). This model has proved useful in guiding the development of four introductory programmes during 2009 and 2010. As a result of this experience, we have amended and updated our programme delivery strategies. We see this process as organic and ever changing, thus these reflections are a snap shot of our current thinking which we have no doubt will evolve as we proceed with future programmes. This booklet will act as a guide for our upcoming programmes in 2010 and 2011 and we believe it may also offer guidance to others who will be involved in the delivery of CBT training within the Irish Mental Health Service.This resource was contributed by The National Documentation Centre on Drug Use.
