    Pavla Fajtová

    Full Text Available Blood flukes of the genus Schistosoma cause schistosomiasis, a parasitic disease that infects over 240 million people worldwide, and for which there is a need to identify new targets for chemotherapeutic interventions. Our research is focused on Schistosoma mansoni prolyl oligopeptidase (SmPOP from the serine peptidase family S9, which has not been investigated in detail in trematodes.We demonstrate that SmPOP is expressed in adult worms and schistosomula in an enzymatically active form. By immunofluorescence microscopy, SmPOP is localized in the tegument and parenchyma of both developmental stages. Recombinant SmPOP was produced in Escherichia coli and its active site specificity investigated using synthetic substrate and inhibitor libraries, and by homology modeling. SmPOP is a true oligopeptidase that hydrolyzes peptide (but not protein substrates with a strict specificity for Pro at P1. The inhibition profile is analogous to those for mammalian POPs. Both the recombinant enzyme and live worms cleave host vasoregulatory, proline-containing hormones such as angiotensin I and bradykinin. Finally, we designed nanomolar inhibitors of SmPOP that induce deleterious phenotypes in cultured schistosomes.We provide the first localization and functional analysis of SmPOP together with chemical tools for measuring its activity. We briefly discuss the notion that SmPOP, operating at the host-parasite interface to cleave host bioactive peptides, may contribute to the survival of the parasite. If substantiated, SmPOP could be a new target for the development of anti-schistosomal drugs.

    This paper provides a framework for evaluating how market participants' beliefs about foreign exchange target zones change as they learn about central bank intervention policy. In order to examine this behavior, we first generalize the standard target zone model to allow for intra-marginal intervention. Intra-marginal intervention implies that the position of market participants' beliefs about the target zone can be determined from their beliefs about the likelihood of intervention. As an app...

    Schistosomosis has been recognised as one of the major parasitic diseases of livestock and human beings. Schistosoma spindale is the major cause of visceral schistosomosis among bovines of Kerala State. Besides pathology in animals, it has been long known that cercariae of S. spindale are a common cause of dermatitis in human beings in Asia. However, detection of this disease based on coprology has underestimated the prevalence of this economically important disease among cattle of the State. An efficient diagnostic tool providing unequivocal evidence of infection in living animals is perhaps, the key to formulate and deliver control measures to the target population. It is also crucial for an enhanced understanding of parasite epidemiology. The utility of excretory-secretory proteins as diagnostic and vaccine candidates for schistosomosis has been a focus of medical research since long. There exists a paucity of information with regard to analysis of ES proteins of S. spindale and their incorporation to develop sensitive and specific serodiagnostic tool. Hence a study was designed to evaluate the efficacy of Dot-ELISA incorporating different antigens of S. spindale and to validate the test under field conditions. PMID:27065623

    Full Text Available Abstract Background Targeting social isolation in older people is a growing public health concern. The proportion of older people in society has increased in recent decades, and it is estimated that approximately 25% of the population will be aged 60 or above within the next 20 to 40 years. Social isolation is prevalent amongst older people and evidence indicates the detrimental effect that it can have on health and wellbeing. The aim of this review was to assess the effectiveness of interventions designed to alleviate social isolation and loneliness in older people. Methods Relevant electronic databases (MEDLINE, EMBASE, ASSIA, IBSS, PsycINFO, PubMed, DARE, Social Care Online, the Cochrane Library and CINAHL were systematically searched using an extensive search strategy, for randomised controlled trials and quasi-experimental studies published in English before May 2009. Additional articles were identified through citation tracking. Studies were included if they related to older people, if the intervention aimed to alleviate social isolation and loneliness, if intervention participants were compared against inactive controls and, if treatment effects were reported. Two independent reviewers extracted data using a standardised form. Narrative synthesis and vote-counting methods were used to summarise and interpret study data. Results Thirty two studies were included in the review. There was evidence of substantial heterogeneity in the interventions delivered and the overall quality of included studies indicated a medium to high risk of bias. Across the three domains of social, mental and physical health, 79% of group-based interventions and 55% of one-to-one interventions reported at least one improved participant outcome. Over 80% of participatory interventions produced beneficial effects across the same domains, compared with 44% of those categorised as non-participatory. Of interventions categorised as having a theoretical basis, 87

    The human gut harbors >100 trillion microbial cells, which influence the nutrition, metabolism, physiology, and immune function of the host. Here, we review the quantitative and qualitative changes in gut microbiota of patients with CKD that lead to disturbance of this symbiotic relationship, how this may contribute to the progression of CKD, and targeted interventions to re-establish symbiosis. Endotoxin derived from gut bacteria incites a powerful inflammatory response in the host organism. Furthermore, protein fermentation by gut microbiota generates myriad toxic metabolites, including p-cresol and indoxyl sulfate. Disruption of gut barrier function in CKD allows translocation of endotoxin and bacterial metabolites to the systemic circulation, which contributes to uremic toxicity, inflammation, progression of CKD, and associated cardiovascular disease. Several targeted interventions that aim to re-establish intestinal symbiosis, neutralize bacterial endotoxins, or adsorb gut-derived uremic toxins have been developed. Indeed, animal and human studies suggest that prebiotics and probiotics may have therapeutic roles in maintaining a metabolically-balanced gut microbiota and reducing progression of CKD and uremia-associated complications. We propose that further research should focus on using this highly efficient metabolic machinery to alleviate uremic symptoms. PMID:24231662

  9. Transcription factors: molecular targets for prostate cancer intervention by phytochemicals.

    With increasing incidence of cancer at most of the sites, and growing economic burden and associated psychological and emotional trauma, it is becoming clearer that more efforts are needed for cancer cure. Since most of the chemotherapeutic drugs are non-selective because they are also toxic to the normal cells, new and improved strategies are needed that selectively target the killing of cancer cells. Since aberrant activation of numerous signaling pathways is a key element of cancer cell survival and growth, blocking all of them is not that practical, which leads to the step where most of them commonly converge; the transcription factors. Recent research efforts, therefore, are also directed on targeting the activity and activation of transcription factors, which ultimately control the expression of genes that are involved in almost all aspects of cell biology. One class of agents that is becoming increasingly successful, not only in targeting signaling cascades, but also transcription factors is phytochemicals present in diet and those consumed as supplement. The added advantage with these agents is that they are mostly non-toxic when compared to chemotherapeutic agents. This review focuses on the efficacy of various phytochemicals in targeting transcription factors such as AR, Sp1, STATs, E2F, Egr1, c-Myc, HIF-1 alpha, NF-kappaB, AP-1, ETS2, GLI and p53 in the context of prostate cancer intervention.

    Professional trainings through the use of webinar format are widely used, but participant feedback is seldom studied. In the spring of 2013, 83 nephrology social workers participated in weekly webinar trainings to learn how to implement Symptom Targeted Intervention (STI) into their clinical practice. At the end of the project, participants were asked to complete an online questionnaire to provide feedback on the perceived value and effectiveness of the trainings. Sixty-eight participants completed the questionnaire. The results indicate that social workers found the webinar trainings to be very useful and wanted the trainings to continue beyond the project. Based on participant feedback, clinical training and case presentation through the use of ongoing webinars is a useful education modality for nephrology professionals, but more research is indicated to evaluate how best to utilize webinars to maximize learning.

    The tumor microenvironment is known to play a pivotal role in driving cancer progression and governing response to therapy. This is of significance in pancreatic cancer where the unique pancreatic tumor microenvironment, characterized by its pronounced desmoplasia and fibrosis, drives early stages of tumor progression and dissemination, and contributes to its associated low survival rates. Several molecular factors that regulate interactions between pancreatic tumors and their surrounding stroma are beginning to be identified. Yet broader physiological factors that influence these interactions remain unclear. Here, we discuss a series of preclinical and mechanistic studies that highlight the important role chronic stress plays as a physiological regulator of neural-tumor interactions in driving the progression of pancreatic cancer. These studies propose several approaches to target stress signaling via the β-adrenergic signaling pathway in order to slow pancreatic tumor growth and metastasis. They also provide evidence to support the use of β-blockers as a novel therapeutic intervention to complement current clinical strategies to improve cancer outcome in patients with pancreatic cancer.

    RNA-Periostin LNCap cells growed slowly in vitro and in vivo. The tissues of xenografts as PCa were verificated by HE staining. Additionally, the weak positive Periostin expressed tumor cells could be seen in the tissues of 6 xenografts from the group of down-regulated Periostin LNCap cells which had a significant decrease of the amount of Periostin compared to the other two group. Furthermore, our results demonstrated that sliencing Periostin could inhibit migration of LNCap cells in vitro. Conclusions Our data indicates that Periostin as an up-regulated protein in PCa may be a promising target of therapeutical intervention for PCa in future.

  2. Intervention development to reduce musculoskeletal disorders: Is the process on target?

    Science.gov (United States)

    Oakman, Jodi; Rothmore, Paul; Tappin, David

    2016-09-01

    Work related musculoskeletal disorders remain an intractable OHS problem. In 2002, Haslam proposed applying the stage of change model to target ergonomics interventions and other health and safety prevention activities. The stage of change model proposes that taking into account an individual's readiness for change in developing intervention strategies is likely to improve uptake and success. This paper revisits Haslam's proposal in the context of interventions to reduce musculoskeletal disorders. Effective MSD interventions require a systematic approach and need to take into account a combination of measures. Research evidence suggests that in practice, those charged with the management of MSDs are not consistently adopting such an approach. Consequently, intervention development may not represent contemporary best practice. We propose a potential method of addressing this gap is the stage of change model, and use a case study to illustrate this argument in tailoring intervention development for managing MSDs.

  3. Alveolar bone loss: mechanisms, potential therapeutic targets, and interventions.

    2014-05-01

    This article reviews recent research into mechanisms underlying bone resorption and highlights avenues of investigation that may generate new therapies to combat alveolar bone loss in periodontitis. Several proteins, signaling pathways, stem cells, and dietary supplements are discussed as they relate to periodontal bone loss and regeneration. RGS12 is a crucial protein that mediates osteoclastogenesis and bone destruction, and a potential therapeutic target. RGS12 likely regulates osteoclast differentiation through regulating calcium influx to control the calcium oscillation-NFATc1 pathway. A working model for RGS10 and RGS12 in the regulation of Ca(2+) oscillations during osteoclast differentiation is proposed. Initiation of inflammation depends on host cell-microbe interactions, including the p38 mitogen-activated protein kinase (MAPK) signaling pathway. Oral p38 inhibitors reduced lipopolysaccharide (LPS)-induced bone destruction in a rat periodontitis model but showed unsatisfactory safety profiles. The p38 substrate MK2 is a more specific therapeutic target with potentially superior tolerability. Furthermore, MKP-1 shows anti-inflammatory activity, reducing inflammatory cytokine biosynthesis and bone resorption. Multipotent skeletal stem cell (SSC) populations exist within the bone marrow and periosteum of long bones. These bone-marrow-derived SSCs and periosteum-derived SSCs have shown therapeutic potential in several applications, including bone and periodontal regeneration. The existence of craniofacial bone-specific SSCs is suggested based on existing studies. The effects of calcium, vitamin D, and soy isoflavone supplementation on alveolar and skeletal bone loss in post-menopausal women were investigated. Supplementation resulted in stabilization of forearm bone mass density and a reduced rate of alveolar bone loss over 1 yr, compared with placebo. Periodontal attachment levels were also well-maintained and alveolar bone loss suppressed during 24 wk of

  7. Developing Internet interventions to target the individual impact of stigma in health conditions

    Directory of Open Access Journals (Sweden)

    Neil Thomas

    2015-09-01

    Full Text Available A number of health problems are associated with significant stigma, a social phenomenon in which individuals become the object of negative stereotypes. In addition to experiencing negative reactions from others, stigmatised individuals and groups can experience harmful consequences when they internalise these negative prevailing attitudes. The objective of this paper was to consider the potential to develop Internet-based health-related interventions explicitly targeting the effects of stigma on the individual. A review of the literature was conducted to synthesise current conceptualisations of stigma and self-stigma across a number of groups, and to identify current intervention developments. Self-stigma reduction strategies developed for in-person services include cognitive reframing, myth busting, contact with other members of the stigmatised group, and disclosure promotion. The development and provision of interventions targeting self-stigma within an online environment is in its infancy. Our review considers there to be particular potential of online interventions for this target, associated with the capacity of the Internet to promote having contact with peers within one’s stigmatised group, and for user interaction and empowerment. We conclude that self-stigma is a domain in which there is significant potential for innovation with health-related interventions, and provide a number of recommendations for online intervention development.

    2014-01-01

    Public health interventions comprising information dissemination to affect behavioral adjustment have long been a significant component of public health campaigns. However, there has been limited development of public health intervention systems to make use of advances in mobile computing and telecommunications technologies. Such developments pose significant challenges to privacy and security where potentially sensitive data may be collected. In our previous work we identified and demonstrated the feasibility of using mobile devices as anonymous public health data collection devices as part of a Health Participatory Sensing Network (HPSN). An advanced capability of these networks extended in this paper would be the ability to distribute, apply, report on and analyze the usage and effectiveness of targeted public health interventions in an anonymous way. In this paper we describe such a platform, its place in the HPSN and demonstrate its feasibility through an implementation. PMID:25570789

In this article, pilot evaluation findings for a targeted public health behavior change intervention, delivered via a website and web-app, aiming to increase uptake of sexual health services among 13-19-year olds are reported. A pre-post questionnaire-based design was used. Matched baseline and follow-up data were identified from 148 respondents aged 13-18 years. Outcome measures were self-reported service access, self-reported intention to access services and beliefs about services and service access identified through needs analysis. Objective service access data provided by local sexual health services were also analyzed. Analysis suggests the intervention had a significant positive effect on psychological barriers to and antecedents of service access among females. Males, who reported greater confidence in service access compared with females, significantly increased service access by time 2 follow-up. Available objective service access data support the assertion that the intervention may have led to increases in service access. There is real promise for this novel digital intervention. Further evaluation is planned as the model is licensed to and rolled out by other local authorities in the United Kingdom. PMID:26928566

    In the past decades, portion sizes of high-caloric foods and drinks have increased and can be considered an important environmental obesogenic factor. This paper describes a research project in which the feasibility and effectiveness of environmental interventions targeted at portion size was evaluated. The studies that we conducted revealed that portion size labeling, offering a larger variety of portion sizes, and proportional pricing (that is, a comparable price per unit regardless of the size) were considered feasible to implement according to both consumers and point-of-purchase representatives. Studies into the effectiveness of these interventions demonstrated that the impact of portion size labeling on the (intended) consumption of soft drinks was, at most, modest. Furthermore, the introduction of smaller portion sizes of hot meals in worksite cafeterias in addition to the existing size stimulated a moderate number of consumers to replace their large meals by a small meal. Elaborating on these findings, we advocate further research into communication and marketing strategies related to portion size interventions; the development of environmental portion size interventions as well as educational interventions that improve people's ability to deal with a 'super-sized' environment; the implementation of regulation with respect to portion size labeling, and the use of nudges to stimulate consumers to select healthier portion sizes.

    Disorders of posture, balance, and gait are debilitating motor manifestations of advancing Parkinson's disease requiring rehabilitation intervention. These problems often reflect difficulties with coupling or sequencing posture and locomotion during complex whole body movements linked with falls. Considerable progress has been made with demonstrating the effectiveness of exercise interventions for individuals with Parkinson's disease. However, gaps remain in the evidence base for specific interventions and the optimal content of exercise interventions. Using a conceptual theoretical framework and experimental findings, this perspective and review advances the viewpoint that rehabilitation interventions focused on separate or isolated components of posture, balance, or gait may limit the effectiveness of current clinical practices. It is argued that treatment effectiveness may be improved by directly targeting posture and locomotion coupling problems as causal factors contributing to balance and gait dysfunction. This approach may help advance current clinical practice and improve outcomes in rehabilitation for persons with Parkinson's disease. “. . .postural activity should be regarded as a function in its own right and not merely as a component of movement. . .” James Purdon Martin PMID:22295253

    The editorial of the new-year issue of Nature 2010 features "A decade for psychiatric disorders". The DALY estimation clearly shows that psychiatric disorders are the top source for burden of diseases to the individual life and society. Schizophrenia is a most devastating psychiatric disorder in which the onset is usually at youth and the cognitive dysfunction persists for life-long in some patients. Schizophrenia is associated with neurodevelopmental abnormalities. It has been unknown whether post-onset progressive pathology is also present in schizophrenia until the recent sophistication of in vivo neuroimaging techniques. Longitudinal neuroimaging studies on first-episode schizophrenia have shown a progressive deterioration of structure and function of neocortical regions in the early stage of the disorder. Insult to dendritic spines through glutamatergic dysfunction may underlie this process, which may in turn be a promising molecular target for intervention to improve the functional outcome of schizophrenia. More recently, the question of whether early intervention can be targeted at prodromal stage of schizophrenia has called special attention in psychiatry. In University of Tokyo, the integrative neuroimaging studies for schizophrenia targeting early intervention and prevention (IN-STEP) is ongoing. Through these efforts, we would like to contribute to the establishment of "youth mental health", where every youth in the community can know, prevent, and have easy access to needs- and value-based services, and pursue mental well-being and recovery.

  20. Why use of interventions targeting outdoor biting mosquitoes will be necessary to achieve malaria elimination

    2012-06-01

    Full Text Available By definition, elimination of malaria means permanent reduction to zero of locally incidence of infections. Achieving this goal among other reasons, it requires fully understanding on where and when persons are most exposed to malaria vectors as these are fundamental for targeting interventions to achieve maximum impact. While elimination can be possible in some settings with low malaria transmission intensity and dominated with late and indoor biting of vectors using Long Lasting Insecticidal Nets (LLIN and Indoor Residual Spraying (IRs, it’s difficult and even impossible in areas with high and where majority of human exposure to transmission occurs outside human dwellings. Recently in response to wide spread use of LLIN and IRS, human risk of exposure to transmission is increasingly spread across the entire night so that much of it occurs outdoors and before bed time. This modification of vector populations and behaviour has now been reported from across Africa, Asia and from the Solomon Islands. Historical evidence shows that even in areas with intervention coverage exceeding 90% of human population it was so hard to even push prevalence down below the pre elimination threshold of 1% being compromised mainly with the outdoor residual transmission. Malaria control experts must however continue to deliver interventions that tackle indoor transmission but considerable amount of resources that target mosquitoes outside of houses and outside of sleeping hours will therefore be required to sustain and go beyond existing levels of malaria control and achieve elimination.

    Full Text Available This study examined the impact of a targeted Irish early intervention program on children's emotional and behavioral development using multiple methods to test the robustness of the results. Data on 164 Preparing for Life participants who were randomly assigned into an intervention group, involving home visits from pregnancy onwards, or a control group, was used to test the impact of the intervention on Child Behavior Checklist scores at 24-months. Using inverse probability weighting to account for differential attrition, permutation testing to address small sample size, and quantile regression to characterize the distributional impact of the intervention, we found that the few treatment effects were largely concentrated among boys most at risk of developing emotional and behavioral problems. The average treatment effect identified a 13% reduction in the likelihood of falling into the borderline clinical threshold for Total Problems. The interaction and subgroup analysis found that this main effect was driven by boys. The distributional analysis identified a 10-point reduction in the Externalizing Problems score for boys at the 90th percentile. No effects were observed for girls or for the continuous measures of Total, Internalizing, and Externalizing problems. These findings suggest that the impact of this prenatally commencing home visiting program may be limited to boys experiencing the most difficulties. Further adoption of the statistical methods applied here may help to improve the internal validity of randomized controlled trials and contribute to the field of evaluation science more generally.ISRCTN Registry ISRCTN04631728.

    An increasing number of interventions targeting sedentary behaviour in children have emerged in recent years. Recently published reviews included sedentary behaviour and physical activity interventions. This review critically summarizes evidence on the effectiveness of intervention strategies that exclusively targeted reducing sedentary time in children and adolescents. We performed a systematic literature search in Pubmed, Embase and the Cochrane Library through November 2015. Two independent reviewers selected eligible studies, extracted relevant data and rated the methodological quality using the assessment tool for quantitative studies. We included 21 intervention studies, of which 8 studies scored moderate on methodological quality and 13 studies scored weak. Four out of eight moderate quality studies reported significant beneficial intervention effects.Although descriptions of intervention strategies were not always clearly reported, we identified encouragement of a TV turnoff week and implementing standing desks in classrooms as promising strategies. Due to a lack of high quality studies and inconsistent findings, we found no convincing evidence for the effectiveness of existing interventions targeting solely sedentary behaviour. We recommend that future studies apply mediation analyses to explore which strategies are most effective. Furthermore, to increase the effectiveness of interventions, knowledge of children's motives to engage in sedentary behavior is required, as well as their opinion on potentially effective intervention strategies.

    2008-03-01

    This paper reviews and reflects on six papers, which describe various early home visiting interventions that resulted in positive outcomes, particularly in relation to the mother-infant relationship. The papers were published in a special issue of the Infant Mental Health Journal in 2006. We provide a brief overview of each paper, highlighting the conclusions drawn across the six papers. Key learning points for health visitors in the UK are explored throughout. Suggestions are described for improvements to the way in which health visiting services in the UK are structured in order to further enhance mother-infant relationships. The overall finding is that mother-infant relationships and interactions can be improved through early home visiting interventions over a period of time, and that this prevents childhood problems later on. It is recommended that specific patient groups be targeted and offered tailored programmes of interventions that have a relevant theoretical base, by trained nursing staff who are supported by an infant mental health consultant.

  11. Targeted intervention strategies to optimise diversion of BMW in the Dublin, Ireland region

    International Nuclear Information System (INIS)

    Highlights: → Previous research indicates that targeted strategies designed for specific areas should lead to improved diversion. → Survey responses and GIS model predictions from previous research were the basis for goal setting. → Then logic modelling and behavioural research were employed to develop site-specific management intervention strategies. → Waste management initiatives can be tailored to specific needs of areas rather than one size fits all means currently used. - Abstract: Urgent transformation is required in Ireland to divert biodegradable municipal waste (BMW) from landfill and prevent increases in overall waste generation. When BMW is optimally managed, it becomes a resource with value instead of an unwanted by-product requiring disposal. An analysis of survey responses from commercial and residential sectors for the Dublin region in previous research by the authors proved that attitudes towards and behaviour regarding municipal solid waste is spatially variable. This finding indicates that targeted intervention strategies designed for specific geographic areas should lead to improved diversion rates of BMW from landfill, a requirement of the Landfill Directive 1999/31/EC. In the research described in this paper, survey responses and GIS model predictions from previous research were the basis for goal setting, after which logic modelling and behavioural research were employed to develop site-specific waste management intervention strategies. The main strategies devised include (a) roll out of the Brown Bin (Organics) Collection and Community Workshops in Dun Laoghaire Rathdown, (b) initiation of a Community Composting Project in Dublin City (c) implementation of a Waste Promotion and Motivation Scheme in South Dublin (d) development and distribution of a Waste Booklet to promote waste reduction activities in Fingal (e) region wide distribution of a Waste Booklet to the commercial sector and (f) Greening Irish Pubs Initiative.

    Complement dysregulation is increasingly recognized as an important pathogenic driver in a number of clinical disorders. Complement-triggered pathways intertwine with key inflammatory and tissue destructive processes that can either increase the risk of disease or exacerbate pathology in acute or chronic conditions. The launch of the first complement-targeted drugs in the clinic has undeniably stirred the field of complement therapeutic design, providing new insights into complement's contribution to disease pathogenesis and also helping to leverage a more personalized, comprehensive approach to patient management. In this regard, a rapidly expanding toolbox of complement therapeutics is being developed to address unmet clinical needs in several immune-mediated and inflammatory diseases. Elegant approaches employing both surface-directed and fluid-phase inhibitors have exploited diverse components of the complement cascade as putative points of therapeutic intervention. Targeting C3, the central hub of the system, has proven to be a promising strategy for developing biologics as well as small-molecule inhibitors with clinical potential. Complement modulation at the level of C3 has recently shown promise in preclinical primate models, opening up new avenues for therapeutic intervention in both acute and chronic indications fueled by uncontrolled C3 turnover. This review highlights recent developments in the field of complement therapeutics, focusing on C3-directed inhibitors and alternative pathway (AP) regulator-based approaches. Translational perspectives and considerations are discussed, particularly with regard to the structure-guided drug optimization and clinical advancement of a new generation of C3-targeted peptidic inhibitors.

    International Nuclear Information System (INIS)

    Objective: to investigate the clinical value of C-arm CT-guided targeted puncturing technique in performing non, vascular interventional biopsy or interventional therapy. Methods: Thirty, one patients, who were encountered in authors' hospital during the period from July 2010 to September 2010, were involved in this study. C-arm CT-guided percutaneous targeted puncturing biopsy or interventional therapy was performed in all 31 patients. All patients had complete clinical data. The complications and positive rate of biopsy were recorded and analyzed. Results: Under C-arm CT-guidance, percutaneous interventional therapy was carried out in 13 patients. The interventional procedures included radiofrequency ablation therapy for hepatic cellular carcinoma (n=2), pelvic abscess draining (n=1), hepatic abscess draining (n=1), ethanol injection for liver cancer (n=4), sclerotic therapy with ethanol injection for renal cyst (n=2), sclerotic therapy with ethanol injection for liver cyst (n=2) and catheter-indwelling drainage for pancreatic pseudocyst (n=1). percutaneous interventional biopsy was performed in the remaining 18 cases, including liver (n=4), lung (n=7), mediastinum (n=2), bone and soft tissue (n=4) and neck mass (n=1). All the procedures were successfully accomplished, no technique, related complications occurred during the operation. For biopsy examination in 18 cases, the positive rate was 94.4% (17/18) and false, negative results was seen in one case with lung lesion. Conclusion: The percutaneous targeted puncturing technique with C, arm CT-guidance combines the advantages of both CT scanning and fluoroscopy. The use of real, time road, mapping function can effectively guide the puncturing and therapeutic management, which can not only optimize the workflow, save the operation time, but also improve the success rate and technical safety. Therefore, it is of great value to popularize this targeted puncturing technique. (authors)

    IMPORTANCE Indwelling devices (eg, urinary catheters and feeding tubes) are often used in nursing homes (NHs). Inadequate care of residents with these devices contributes to high rates of multidrug-resistant organisms (MDROs) and device-related infections in NHs. OBJECTIVE To test whether a multimodal targeted infection program (TIP) reduces the prevalence of MDROs and incident device-related infections. DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial at 12 community-based NHs from May 2010 to April 2013. Participants were high-risk NH residents with urinary catheters, feeding tubes, or both. INTERVENTIONS Multimodal, including preemptive barrier precautions, active surveillance for MDROs and infections, and NH staff education. MAIN OUTCOMES AND MEASURES The primary outcome was the prevalence density rate of MDROs, defined as the total number of MDROs isolated per visit averaged over the duration of a resident's participation. Secondary outcomes included new MDRO acquisitions and new clinically defined device-associated infections. Data were analyzed using a mixed-effects multilevel Poisson regression model (primary outcome) and a Cox proportional hazards model (secondary outcome), adjusting for facility-level clustering and resident-level variables. RESULTS In total, 418 NH residents with indwelling devices were enrolled, with 34 174 device-days and 6557 anatomic sites sampled. Intervention NHs had a decrease in the overall MDRO prevalence density (rate ratio, 0.77; 95% CI, 0.62–0.94). The rate of new methicillin-resistant Staphylococcus aureus acquisitions was lower in the intervention group than in the control group (rate ratio, 0.78; 95% CI, 0.64–0.96). Hazard ratios for the first and all (including recurrent) clinically defined catheter-associated urinary tract infections were 0.54 (95% CI, 0.30–0.97) and 0.69 (95% CI, 0.49–0.99), respectively, in the intervention group and the control group. There were no reductions in new vancomycin

    There is increasing appreciation that complement dysregulation lies at the heart of numerous immune-mediated and inflammatory disorders. Complement inhibitors are therefore being evaluated as new therapeutic options in various clinical translation programs and the first clinically approved complement-targeted drugs have profoundly impacted the management of certain complement-mediated diseases. Among the many members of the intricate protein network of complement, the central component C3 represents a 'hot-spot' for complement-targeted therapeutic intervention. C3 modulates both innate and adaptive immune responses and is linked to diverse immunomodulatory systems and biological processes that affect human pathophysiology. Compelling evidence from preclinical disease models has shown that C3 interception may offer multiple benefits over existing therapies or even reveal novel therapeutic avenues in disorders that are not commonly regarded as complement-driven, such as periodontal disease. Using the clinically developed compstatin family of C3 inhibitors and periodontitis as illustrative examples, this review highlights emerging therapeutic concepts and developments in the design of C3-targeted drug candidates as novel immunotherapeutics for oral and systemic inflammatory diseases.

    Full Text Available Abstract Background Encouraging men to make more effective use of (preventive health services is considered one way of improving their health. The aim of this study was to appraise the available evidence of effective interventions aimed at improving men's health. Methods Systematic review of relevant studies identified through 14 electronic databases and other information resources. Results were pooled within health topic and described qualitatively. Results Of 11,749 citations screened, 338 articles were assessed and 27 met our inclusion criteria. Most studies were male sex-specific, i.e. prostate cancer screening and testicular self-examination. Other topics included alcohol, cardiovascular disease, diet and physical activity, skin cancer and smoking cessation. Twenty-three interventions were effective or partially effective and 18 studies satisfied all quality criteria. Conclusion Most of the existing evidence relates to male sex-specific health problems as opposed to general health concerns relevant to both men and women. There is little published evidence on how to improve men's uptake of services. We cannot conclude from this review that targeting men works better than providing services for all people. Large-scale studies are required to help produce evidence that is sufficiently robust to add to the small evidence base that currently exists in this field.

    2013-01-01

    Full Text Available Recent interest in the early course of schizophrenia accentuated altered cognition prior to the onset. Ultrahigh risk (UHR individuals with attenuated positive symptoms and transient psychotic episodes demonstrate neurocognitive deficits across multiple domains such as memory, executive functioning, and processing speed which are consistent with similar disturbances identified in patients with a first episode of schizophrenia. Cognitive remediation (CR approaches representing a broad set of activities are aimed to restore or improve cognitive functioning. CR proved to be effective in modulating the cognitive dysfunction in schizophrenia but is rarely used in ultrahigh risk individuals. From the clinical prospective, a better understanding of cognitive functioning in at-risk states is essential for the development of optimal early intervention models. In the review, we highlight the intervention targets, notably the specific cognitive deficits in at risk individuals which preceed the transition to psychosis and emphasize the need of the additional studies using CR approaches in UHR group aiming to enhance cognition and therefore mediate functional improvement.

    To apply the joint marketing principle as a new intervention approach for targeting men who have sex with men (MSM) who are often difficult to reach in societies with discrimination towards homosexuality and HIV/AIDS. A pilot intervention according to the principles of joint marketing was carried out by the CDC in Shenzhen, China, in MSM social venues. A self-designed questionnaire of HIV knowledge, condom use, and access to HIV-related services was used before and after the pilot intervention to evaluate its effectiveness. The CDC supported gatekeepers of MSM social venues in running their business and thereby increasing their respectability and income. In return, the gatekeepers cooperated with the CDC in reaching the MSM at the venues with health promotion messages and materials. Thus a win-win situation was created, bringing together two noncompetitive parties in reaching out to a shared customer, the MSM. The pilot intervention succeeded in demonstrating acceptability and feasibility of the joint marketing approach targeting MSM. HIV knowledge, the rate of condom use, and access to HIV-related services of participants in the pilot intervention increased significantly. The joint marketing intervention is an innovative way to create synergies between the gatekeepers of MSM social venues and public health officials for reaching and potentially changing HIV high-risk behaviors among MSM.

    Full Text Available BACKGROUND: Research on the biology of parasites requires a sophisticated and integrated computational platform to query and analyze large volumes of data, representing both unpublished (internal and public (external data sources. Effective analysis of an integrated data resource using knowledge discovery tools would significantly aid biologists in conducting their research, for example, through identifying various intervention targets in parasites and in deciding the future direction of ongoing as well as planned projects. A key challenge in achieving this objective is the heterogeneity between the internal lab data, usually stored as flat files, Excel spreadsheets or custom-built databases, and the external databases. Reconciling the different forms of heterogeneity and effectively integrating data from disparate sources is a nontrivial task for biologists and requires a dedicated informatics infrastructure. Thus, we developed an integrated environment using Semantic Web technologies that may provide biologists the tools for managing and analyzing their data, without the need for acquiring in-depth computer science knowledge. METHODOLOGY/PRINCIPAL FINDINGS: We developed a semantic problem-solving environment (SPSE that uses ontologies to integrate internal lab data with external resources in a Parasite Knowledge Base (PKB, which has the ability to query across these resources in a unified manner. The SPSE includes Web Ontology Language (OWL-based ontologies, experimental data with its provenance information represented using the Resource Description Format (RDF, and a visual querying tool, Cuebee, that features integrated use of Web services. We demonstrate the use and benefit of SPSE using example queries for identifying gene knockout targets of Trypanosoma cruzi for vaccine development. Answers to these queries involve looking up multiple sources of data, linking them together and presenting the results. CONCLUSION/SIGNIFICANCE: The SPSE

    In comparative effectiveness research (CER), often the aim is to contrast survival outcomes between exposure groups defined by time-varying interventions. With observational data, standard regression analyses (e.g., Cox modeling) cannot account for time-dependent confounders on causal pathways between exposures and outcome nor for time-dependent selection bias that may arise from informative right censoring. Inverse probability weighting (IPW) estimation to fit marginal structural models (MSMs) has commonly been applied to properly adjust for these expected sources of bias in real-world observational studies. We describe the application and performance of an alternate estimation approach in such a study. The approach is based on the recently proposed targeted learning methodology and consists in targeted minimum loss-based estimation (TMLE) with super learning (SL) within a nonparametric MSM. The evaluation is based on the analysis of electronic health record data with both IPW estimation and TMLE to contrast cumulative risks under four more or less aggressive strategies for treatment intensification in adults with type 2 diabetes already on 2+ oral agents or basal insulin. Results from randomized experiments provide a surrogate gold standard to validate confounding and selection bias adjustment. Bootstrapping is used to validate analytic estimation of standard errors. This application does the following: (1) establishes the feasibility of TMLE in real-world CER based on large healthcare databases; (2) provides evidence of proper confounding and selection bias adjustment with TMLE and SL; and (3) motivates their application for improving estimation efficiency. Claims are reinforced with a simulation study that also illustrates the double-robustness property of TMLE. PMID:24535915

    Full Text Available Abstract Background In view of the epidemiological expansion of dengue worldwide and the availability of new tools and strategies particularly for controlling the primary dengue vector Aedes aegypti, an intervention study was set up to test the efficacy, cost and feasibility of a combined approach of insecticide treated materials (ITMs alone and in combination with appropriate targeted interventions of the most productive vector breeding-sites. Methods The study was conducted as a cluster randomized community trial using “reduction of the vector population” as the main outcome variable. The trial had two arms: 10 intervention clusters (neighborhoods and 10 control clusters in the town of Poptun Guatemala. Activities included entomological assessments (characteristics of breeding-sites, pupal productivity, Stegomyia indices at baseline, 6 weeks after the first intervention (coverage of window and exterior doorways made of PermaNet 2.0 netting, factory treated with deltamethrin at 55 mg/m2, and of 200 L drums with similar treated material and 6 weeks after the second intervention (combination of treated materials and other suitable interventions targeting productive breeding-sites i.e larviciding with Temephos, elimination etc.. The second intervention took place 17 months after the first intervention. The insecticide residual activity and the insecticidal content were also studied at different intervals. Additionally, information about demographic characteristics, cost of the intervention, coverage of houses protected and satisfaction in the population with the interventions was collected. Results At baseline (during the dry season a variety of productive container types for Aedes pupae were identified: various container types holding >20 L, 200 L drums, washbasins and buckets (producing 83.7% of all pupae. After covering 100% of windows and exterior doorways and a small number of drums (where the commercial cover could be fixed in 970 study

  9. Head-and-Neck Target Delineation Among Radiation Oncology Residents After a Teaching Intervention: A Prospective, Blinded Pilot Study

    International Nuclear Information System (INIS)

    Purpose: We conducted this study to determine the feasibility of incorporating a teaching intervention on target delineation into the educational curriculum of a radiation oncology residency program and to assess the short-term effects on resident skills. Methods and Materials: The study schema consisted of a baseline evaluation, the teaching intervention, and a follow-up evaluation. At the baseline evaluation, the participants contoured three clinical tumor volumes (CTVs) (70 Gy, 59.4 Gy, and 54 Gy) on six contrast-enhanced axial computed tomography images of a de-identified patient with Stage T2N2bM0 squamous cell carcinoma of the right base of the tongue. The participants attended a series of head-and-neck oncology and anatomy seminars. The teaching intervention consisted of a didactic lecture and an interactive hands-on practical session designed to improve the knowledge and skills for target delineation in the head and neck. At the follow-up evaluation, the residents again contoured the CTVs. Results: Of the 14 eligible residents, 11 (79%) actually participated in the study. For all participants, but especially for those who had not had previous experience with head-and-neck target delineation, the teaching intervention was associated with improvement in the delineation of the node-negative neck (CTV 54 Gy contour). Regardless of clinical experience, participants had difficulty determining what should be included in the CTV 59.4 Gy contour to ensure adequate coverage of potential microscopic disease. Conclusion: Incorporating a teaching intervention into the education curriculum of a radiation oncology residency program is feasible and was associated with short-term improvements in target delineation skills. Subsequent interventions will require content refinement, additional validation, longer term follow-up, and multi-institutional collaboration

    Mast cells are important in the initiation of ocular inflammation, but the consequences of mast cell degranulation on ocular pathology remain uncharacterized. We induced mast cell degranulation by local subconjunctival injection of compound 48/80. Initial degranulation of mast cells was observed in the choroid 15 minutes after the injection and increased up to 3 hours after injection. Clinical signs of anterior segment inflammation paralleled mast cell degranulation. With the use of optical coherence tomography, dilation of choroidal vessels and serous retinal detachments (SRDs) were observed and confirmed by histology. Subconjunctival injection of disodium cromoglycate significantly reduced the rate of SRDs, demonstrating the involvement of mast cell degranulation in posterior segment disorders. The infiltration of polymorphonuclear and macrophage cells was associated with increased ocular media concentrations of tumor necrosis factor-α, CXCL1, IL-6, IL-5, chemokine ligand 2, and IL-1β. Analysis of the amounts of vascular endothelial growth factor and IL-18 showed an opposite evolution of vascular endothelial growth factor compared with IL-18 concentrations, suggesting that they regulate each other's production. These findings suggest that the local degranulation of ocular mast cells provoked acute ocular inflammation, dilation, increased vascular permeability of choroidal vessels, and SRDs. The involvement of mast cells in retinal diseases should be further investigated. The pharmacologic inhibition of mast cell degranulation may be a potential target for intervention. PMID:26166807

    Full Text Available Schistosoma flatworm parasites cause schistosomiasis, a chronic and debilitating disease of poverty in developing countries. Praziquantel is employed for treatment and disease control. However, its efficacy spectrum is incomplete (less active or inactive against immature stages of the parasite and there is a concern of drug resistance. Thus, there is a need to identify new drugs and drug targets.We show that RNA interference (RNAi of the Schistosoma mansoni ortholog of human polo-like kinase (huPLK1 elicits a deleterious phenotypic alteration in post-infective larvae (schistosomula or somules. Phenotypic screening and analysis of schistosomula and adult S. mansoni with small molecule inhibitors of huPLK1 identified a number of potent anti-schistosomals. Among these was a GlaxoSmithKline (GSK benzimidazole thiophene inhibitor that has completed Phase I clinical trials for treatment of solid tumor malignancies. We then obtained GSKs Published Kinase Inhibitor Sets (PKIS 1 and 2, and phenotypically screened an expanded series of 38 benzimidazole thiophene PLK1 inhibitors. Computational analysis of controls and PLK1 inhibitor-treated populations of somules demonstrated a distinctive phenotype distribution. Using principal component analysis (PCA, the phenotypes exhibited by these populations were mapped, visualized and analyzed through projection to a low-dimensional space. The phenotype distribution was found to have a distinct shape and topology, which could be elicited using cluster analysis. A structure-activity relationship (SAR was identified for the benzimidazole thiophenes that held for both somules and adult parasites. The most potent inhibitors produced marked phenotypic alterations at 1-2 μM within 1 h. Among these were compounds previously characterized as potent inhibitors of huPLK1 in cell assays.The reverse genetic and chemical SAR data support a continued investigation of SmPLK1 as a possible drug target and/or the prosecution of

    Over the past three decades, the potential effects of lifestyle interventions targeting changes in body weight and composition (weight, body mass index, fat mass, waist circumference) among adults with an intellectual disability (ID) have been examined in various systematic reviews. Nevertheless, since the middle of the 1980s, the potential effects of these interventions for youth with an ID remain an open question. The purpose of this article is to review the effects of lifestyle interventions targeting changes in body weight and composition among youth with an ID. This review will focus on changes in body weight and composition, healthy lifestyle, and secondary health conditions. A systematic review of English- and French-language studies, published between 1981 and 2013, was performed on Academic Search Complete, PsycARTICLES, Medline and Scopus. The nine studies included in this review focused mainly on: a sample with a wide age range (e.g., 7-22 years); males; overweight-obese youth having a mild-to-moderate ID with Down or Prader-Willi syndrome; physical activity interventions; cohort pre- and post-test designs with/without a control group; and changes in body weight and composition. Taken together, results from these studies suggest successful changes in weight, body mass index and fat mass. However, intervention effects on healthy lifestyle and secondary health conditions are scarce and inconclusive. Given the weaknesses of the reviewed studies, the present findings should be considered preliminary and indicative of the need for future research. PMID:24830882

  18. Enhancement of in situ biodegradation of organic compounds in groundwater by targeted pump and treat intervention

    International Nuclear Information System (INIS)

    Highlights: • Pumping reduces contaminant toxicity below levels which stimulate in situ biodegradation. • Pumping increases the mixing of background oxidants into the plume for anaerobic respiration. • Bacterial sulphate reduction is very sensitive to contaminant concentrations. • Stable isotope analysis confirms the contribution of different biodegradation processes. • Targeted pump and treatment can enhance the natural attenuation of complex plumes. - Abstract: This study demonstrates the value of targeted pump and treatment (PAT) to enhance the in situ biodegradation of organic contaminants in groundwater for improved restoration. The approach is illustrated for a plume of phenolic compounds in a sandstone aquifer, where PAT is used for hydraulic containment and removal of dissolved phase contaminants from specific depth intervals. Time-series analysis of the plume hydrochemistry and stable isotope composition of dissolved species (δ34S-SO4, δ13C-CH4, δ13C-TDIC (TDIC = Total Dissolved Inorganic Carbon)) in groundwater samples from high-resolution multilevel samplers were used to deduce changes in the relative significance of biodegradation processes and microbial activity in the plume, induced by the PAT system over 3 years. The PAT system has reduced the maximum contaminant concentrations (up to 6800 mg L−1 total phenols) in the plume by 50% to ∼70% at different locations. This intervention has (i) stimulated in situ biodegradation in general, with an approximate doubling of contaminant turnover based on TDIC concentration, which has increased from <200 mg L−1 to >350 mg L−1, (ii) enhanced the activity of SO4-reducing microorganisms (marked by a declining SO4 concentration with corresponding increase in SO4-δ34S to values >7–14‰V-CDT relative to background values of 1.9–6.5‰V-CDT), and (iii) where the TDIC increase is greatest, has changed TDIC-δ13C from values of −10 to −15‰V-PDB to ∼−20‰V-PDB. This indicates an

    In recent years water companies have started to adopt catchment management to reduce diffuse pollution in drinking water supply areas. The heterogeneity of catchments and the range of pollutants that must be removed to meet the EU Drinking Water Directive (98/83/EC) limits make it difficult to prioritise areas of a catchment for intervention. Thus conceptual frameworks are required that can disaggregate the components of pollutant risk and help water companies make decisions about where to target interventions in their catchments to maximum effect. This paper demonstrates the concept of generalising pollutants in the same framework by reviewing key pollutant processes within a source-mobilisation-delivery context. From this, criteria are developed (with input from water industry professionals involved in catchment management) which highlights the need for a new water industry specific conceptual framework. The new CaRPoW (Catchment Risk to Potable Water) framework uses the Source-Mobilisation-Delivery concept as modular components of risk that work at two scales, source and mobilisation at the field scale and delivery at the catchment scale. Disaggregating pollutant processes permits the main components of risk to be ascertained so that appropriate interventions can be selected. The generic structure also allows for the outputs from different pollutants to be compared so that potential multiple benefits can be identified. CaRPow provides a transferable framework that can be used by water companies to cost-effectively target interventions under current conditions or under scenarios of land use or climate change.

    Modern health care in the field of Medicine, Dentistry and Nursing is grounded in fundamental philosophy and epistemology of translational science. Recently in the U.S major national initiatives have been implemented in the hope of closing the gaps that sometimes exist between the two fundamental components of translational science, the translational research and translational effectiveness. Subsequent to these initiatives, many improvements have been made; however, important bioethical issues and limitations do still exist that need to be addressed. One such issue is the stakeholder engagement and its assessment and validation. Federal, state and local organizations such as PCORI and AHRQ concur that the key to a better understanding of the relationship between translational research and translational effectiveness is the assessment of the extent to which stakeholders are actively engaged in the translational process of healthcare. The stakeholder engagement analysis identifies who the stakeholders are, maps their contribution and involvement, evaluates their priorities and opinions, and accesses their current knowledge base. This analysis however requires conceptualization and validation from the bioethics standpoint. Here, we examine the bioethical dilemma of stakeholder engagement analysis in the context of the person-environment fit (PE-fit) theoretical model. This model is an approach to quantifying stakeholder engagement analysis for the design of patient-targeted interventions. In our previous studies of Alzheimer patients, we have developed, validated and used a simple instrument based on the PE-fit model that can be adapted and utilized in a much less studied pathology as a clinical model that has a wide range of symptoms and manifestations, the temporomandibular joint disorders (TMD). The temporomandibular joint (TMJ) is the jaw joint endowed with sensory and motor innervations that project from within the central nervous system and its dysfunction can

    This article presents a systematic review of qualitative studies focusing on human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) among Black men who have sex with men (BMSM) in the United States. We reviewed studies that were published between 1980 and 2014. Qualitative methods employed in the studies reviewed include in-depth interviews, focus groups, participant observation, and ethnography. We searched several databases (PubMed, PsychINFO, JSTOR, ERIC, Sociological Abstracts, and Google Scholar) for relevant articles using the following broad terms: "Black men" "Black gay/bisexual" or "Black men who have sex with men," and "qualitative" and/or "ethnography." We include 70 studies in this review. The key themes observed across studies were (1) heterogeneity, (2) layered stigma and intersectionality, (3) risk behaviors, (4) mental health, (5) resilience, and (6) community engagement. The review suggests that sexual behavior and HIV-status disclosure, sexual risk taking, substance use, and psychological well-being were contextually situated. Interventions occurring at multiple levels and within multiple contexts are needed to reduce stigma within the Black community. Similarly, structural interventions targeting religious groups, schools, and health care systems are needed to improve the health outcomes among BMSM. Community engagement and using community-based participatory research methods may facilitate the development and implementation of culturally appropriate HIV/AIDS interventions targeting BMSM.

    Full Text Available Background. Dropouts and compliance to exercise interventions targeting bone mineral density (BMD in adults are not well established. The purpose of this study was to address that gap. Methods. Meta-analysis of randomized controlled exercise intervention trials in adults ≥18 years of age. The primary outcomes were dropouts in the exercise and control groups as well as compliance to the exercise interventions. A random-effects model was used to pool results. Moderator analyses were conducted using mixed-effects ANOVA-like models and metaregression. Statistical significance was set at . Results. Thirty-six studies representing 3,297 participants (1,855 exercise, 1,442 control were included. Dropout rates in the exercise and control groups averaged 20.9% (95% CI 16.7%–25.9% and 15.9% (11.8%–21.1% while compliance to exercise was 76.3% (71.7%–80.3%. For both exercise and control groups, greater dropout rates were associated with studies conducted in the USA versus other countries, females versus males, premenopausal versus postmenopausal women, younger versus older participants, longer studies (controls only, and high- versus moderate-intensity training (exercisers only. Greater compliance to exercise was associated with being female, home- or facility-based exercise versus both, and shorter studies. Conclusion. These findings provide important information for researchers and practitioners with respect to exercise programs targeting BMD in adults.

    The purpose of the present study was to examine the effects of three computerized interventions on the reading skills of children with reading disabilities in Grade 2. This longitudinal intervention study included five test sessions over 1 year. Two test points occur before the intervention, and three afterwards. The last follow-up was conducted 1 year after the first measurement. One hundred thirty children in Grade 2 participated in the study. Three groups of children with reading difficulties received computerized training programmes: one aimed at improving word decoding skills and phonological abilities, the second focused on word and sentence levels and the third was a combination of these two training programmes. A fourth group received ordinary special instruction. In addition, there was one comparison group with age-matched typical readers. All groups improved their reading skills. The group that received combined training showed greater improvement than the one with ordinary special instruction and the group of typical readers at two follow-ups. The longitudinal results indicate additional positive results for the group that received the combined training, the majority of students from that group being no longer judged to be needing special education 1 year after the intervention.

    Community-based participatory research (CBPR) was used to design and evaluate the effectiveness of a culturally relevant, science-based intervention for the prevention of childhood obesity in the Commonwealth of the Northern Mariana Islands (CNMI), a US Commonwealth in the western Pacific. This cognitive behavioral lifestyle intervention, Project Familia Giya Marianas (PFGM), was offered during the 2005-2007 school years in all CNMI public elementary schools over eight sessions to primary caregivers of 3rd grade children (N = 407). A crossover design was utilized with half of the schools offering the intervention in the Fall term, while the other half delivered the sessions in the Spring term. The primary outcome measure was change in BMI z-score. There was an intervention-dependent effect on BMI z-score, with program impact being a function of baseline BMI and the number of lessons attended. This effect was most apparent in students whose baseline BMI z-score was in healthy range (>/=5 to solutions to address a complex condition such as childhood obesity. PFGM demonstrated that community participation can be successfully utilized in the development and implementation of childhood obesity prevention programs. PMID:19424164

    2011-06-15

    Elevated wintertime particulate concentrations in the New Zealand cities of Christchurch and Timaru are mostly attributed to the burning of wood and coal for residential heating. A carrot-and-stick approach was adopted for managing air quality in Christchurch, where strict intervention measures were introduced together with a residential heater replacement programme to encourage householders to change to cleaner forms of heating. A similar approach was only recently implemented for Timaru. This paper presents the results of a partial accountability analysis, where the impact of these measures on the target source, PM10 emissions, and PM10, concentrations are quantified. A statistical model was developed to estimate trends in the concentrations, which were tested for significance after accounting for meteorological effects, and to estimate the probability of meeting air quality targets. Results for Christchurch and Timaru are compared to illustrate the impacts of differing levels of intervention on air quality. In Christchurch, approximately 34,000 (76%) open fires and old solid fuel burners were replaced with cleaner heating technology from 2002 to 2009, and total open fires and solid fuel burner numbers decreased by 45%. Over the same time period, estimated PM10 emissions reduced by 71% and PM10 concentrations by 52% (maxima), 36% (winter mean), 26% (winter median) and 41% (meteorology-adjusted winter means). In Timaru, just 3000 (50%) open fires and old solid fuel burners were replaced from 2001 to 2008, with total open fire and solid fuel burner numbers reduced by 24%. PM10 emissions declined by 32%, with low reductions in the PM10 concentrations (maxima decreased by 7%, winter means by 11% and winter medians by 3%). These findings indicate that the combination of stringent intervention measures and financial incentives has led to substantial air quality improvements in Christchurch.

    Despite a high current standard of care in antiretroviral therapy for HIV, multidrug-resistant strains continue to emerge, underscoring the need for additional novel mechanism inhibitors that will offer expanded therapeutic options in the clinic. We report a new class of small molecule antiretroviral compounds that directly target HIV-1 capsid (CA) via a novel mechanism of action. The compounds exhibit potent antiviral activity against HIV-1 laboratory strains, clinical isolates, and HIV-2, and inhibit both early and late events in the viral replication cycle. We present mechanistic studies indicating that these early and late activities result from the compound affecting viral uncoating and assembly, respectively. We show that amino acid substitutions in the N-terminal domain of HIV-1 CA are sufficient to confer resistance to this class of compounds, identifying CA as the target in infected cells. A high-resolution co-crystal structure of the compound bound to HIV-1 CA reveals a novel binding pocket in the N-terminal domain of the protein. Our data demonstrate that broad-spectrum antiviral activity can be achieved by targeting this new binding site and reveal HIV CA as a tractable drug target for HIV therapy. PMID:21170360

    A variety of feeding issues and concerns, including food aversion, food selectivity, and complete food refusal, are not uncommon among children with autism spectrum disorder (ASD). Other underlying issues are often comorbid with the concerns for feeding and ASD. These may include food allergies, gastrointestinal issues, oral motor issues, and swallowing disorders. The refusal to consume particular foods coupled with the inability to tolerate, digest, and absorb these foods can compromise an individual's overall nutrition status. Therefore, a child's behavior toward food and feeding activities has great impact on dietary intake, nutritional status, and growth. This case report is the first to document combined medical, behavioral, and nutritional intervention for a toddler with ASD and comorbid feeding disorder. PMID:27051550

    2012-03-01

    Full Text Available Curcumin, a yellow pigment derived from Curcuma longa Linn, has attracted great interest in the research of cancer during the past decades. Extensive studies documented that curcumin attenuates cancer cell proliferation and promotes apoptosis in vivo and in vitro. Curcumin has been demonstrated to interact with multiple molecules and signal pathways, which makes it a potential adjuvant anti-cancer agent to chemotherapy. Previous investigations focus on the mechanisms of action for curcumin, which is shown to manipulate transcription factors and induce apoptosis in various kinds of human cancer. Apart from transcription factors and apoptosis, emerging studies shed light on latent targets of curcumin against epidermal growth factor receptor (EGFR, microRNAs (miRNA, autophagy and cancer stem cell. The present review predominantly discusses significance of EGFR, miRNA, autophagy and cancer stem cell in lung cancer therapy. Curcumin as a natural phytochemicals could communicate with these novel targets and show synergism to chemotherapy. Additionally, curcumin is well tolerated in humans. Therefore, EGFR-, miRNA-, autophagy- and cancer stem cell-based therapy in the presence of curcumin might be promising mechanisms and targets in the therapeutic strategy of lung cancer.

    Plasmodium falciparum is the parasite responsible for the most lethal form of malaria, an infectious disease that causes a large proportion of childhood deaths and poses a significant barrier to socioeconomic development in many countries. Although antimalarial drugs exist, the repeated emergence and spread of drug-resistant parasites limit their useful lifespan. An alternative strategy that could limit the evolution of drug-resistant parasites is to target host factors that are essential and universally required for parasite growth. Host-targeted therapeutics have been successfully applied in other infectious diseases but have never been attempted for malaria. Here, we report the development of a recombinant chimeric antibody (Ab-1) against basigin, an erythrocyte receptor necessary for parasite invasion as a putative antimalarial therapeutic. Ab-1 inhibited the PfRH5-basigin interaction and potently blocked erythrocyte invasion by all parasite strains tested. Importantly, Ab-1 rapidly cleared an established P. falciparum blood-stage infection with no overt toxicity in an in vivo infection model. Collectively, our data demonstrate that antibodies or other therapeutics targeting host basigin could be an effective treatment for patients infected with multi-drug resistant P. falciparum.

  7. Influence of the Target Vessel on the Location and Area of Maximum Skin Dose during Percutaneous Coronary Intervention

    International Nuclear Information System (INIS)

    Background: A number of cases involving radiation-associated patient skin injury attributable to percutaneous coronary intervention (PCI) have been reported. Knowledge of the location and area of the patient's maximum skin dose (MSD) in PCI is necessary to reduce the risk of skin injury. Purpose: To determine the location and area of the MSD in PCI, and separately analyze the effects of different target vessels. Material and Methods: 197 consecutive PCI procedures were studied, and the location and area of the MSD were calculated by a skin-dose mapping software program: Caregraph. The target vessels of the PCI procedures were divided into four groups based on the American Heart Association (AHA) classification. Results: The sites of the MSD for AHA no.1-3, AHA no.4, and AHA no.11-15 were located mainly on the right back skin, the lower right or center back skin, and the upper back skin areas, respectively, whereas the MSD sites for the AHA no. 5-10 PCI were widely spread. The MSD area for the AHA no. 4 PCI was larger than that for the AHA no. 11-15 PCI (P<0.0001). Conclusion: Although the radiation associated with PCI can be widely spread and variable, we observed a tendency regarding the location and area of the MSD when we separately analyzed the data for different target vessels. We recommend the use of a smaller radiation field size and the elimination of overlapping fields during PCI

  8. Androgen-targeted therapy induced epithelial mesenchymal plasticity and neuroendocrine transdifferentiation in prostate cancer: an opportunity for intervention

    2014-12-01

    Full Text Available Androgens regulate biological pathways to promote proliferation, differentiation and survival of benign and malignant prostate tissue. Androgen receptor targeted therapies exploit this dependence and are used in advanced prostate cancer to control disease progression. Contemporary treatment regimens involve sequential use of inhibitors of androgen synthesis or androgen receptor function. Although targeting the androgen axis has clear therapeutic benefit, its effectiveness is temporary, as prostate tumor cells adapt to survive and grow. The removal of androgens (androgen deprivation has been shown to activate both epithelial-to-mesenchymal transition (EMT and neuroendocrine transdifferentiation programs. EMT has established roles in promoting biological phenotypes associated with tumor progression (migration/invasion, tumor cell survival, cancer stem cell-like properties, resistance to radiation and chemotherapy in multiple human cancer types. Neuroendocrine transdifferentiation in prostate cancer is associated with resistance to therapy, visceral metastasis and aggressive disease. Thus, activation of these programs via inhibition of the androgen axis provides a mechanism by which tumor cells can adapt to promote disease recurrence and progression. Brachyury, Axl, MEK and aurora kinase A are molecular drivers of these programs, and inhibitors are currently in clinical trials to determine therapeutic applications. Understanding tumor cell plasticity will be important in further defining the rational use of androgen targeted therapies clinically and provides an opportunity for intervention to prolong survival of men with metastatic prostate cancer.

    2010-06-01

    Full Text Available Abstract Background Inequities in the utilization of maternal health services impede progress towards the MDG 5 target of reducing the maternal mortality ratio by three quarters, between 1990 and 2015. In Namibia, despite increasing investments in the health sector, the maternal mortality ratio has increased from 271 per 100,000 live births in the period 1991-2000 to 449 per 100,000 live births in 1998-2007. Monitoring equity in the use of maternal health services is important to target scarce resources to those with more need and expedite the progress towards the MDG 5 target. The objective of this study is to measure socio-economic inequalities in access to maternal health services and propose recommendations relevant for policy and planning. Methods Data from the Namibia Demographic and Health Survey 2006-07 are analyzed for inequities in the utilization of maternal health. In measuring the inequities, rate-ratios, concentration curves and concentration indices are used. Results Regions with relatively high human development index have the highest rates of delivery by skilled health service providers. The rate of caesarean section in women with post secondary education is about seven times that of women with no education. Women in urban areas are delivered by skilled providers 30% more than their rural counterparts. The rich use the public health facilities 30% more than the poor for child delivery. Conclusion Most of the indicators such as delivery by trained health providers, delivery by caesarean section and postnatal care show inequities favoring the most educated, urban areas, regions with high human development indices and the wealthy. In the presence of inequities, it is difficult to achieve a significant reduction in the maternal mortality ratio needed to realize the MDG 5 targets so long as a large segment of society has inadequate access to essential maternal health services and other basic social services.

    Directory of Open Access Journals (Sweden)

    Keith B Moore

    2015-01-01

    Full Text Available Both neurons and glia throughout the central nervous system are organized into networks by gap junctions. Among glia, gap junctions facilitate metabolic homeostasis and intercellular communication. Among neurons, gap junctions form electrical synapses that function primarily for communication. However, in neurodegenerative states due to disease or injury gap junctions may be detrimental to survival. Electrical synapses may facilitate hyperactivity and bystander killing among neurons, while gap junction hemichannels in glia may facilitate inflammatory signaling and scar formation. Advances in understanding mechanisms of plasticity of electrical synapses and development of molecular therapeutics to target glial gap junctions and hemichannels offer new hope to pharmacologically limit neuronal degeneration and enhance recovery.

    The purpose of the present study is to show that an independent group contingency (GC) combined with self-management strategies and randomized-reinforcer components can increase the amount of written work and active classroom responding in high school students. Three remedial reading classes and a total of 15 students participated in this study. Students used self-management strategies during independent reading time to increase the amount of writing in their reading logs. They used self-monitoring strategies to record whether or not they performed expected behaviors in class. A token economy using points and tickets was included in the GC to provide positive reinforcement for target responses. The results were analyzed through visual inspection of graphs and effect size computations and showed that the intervention increased the total amount of written words in the students’ reading logs and overall classroom and individual student academic engagement.

    2014-07-01

    Full Text Available While the overall trend in euthanasia has been decreasing nationally, large dogs are at a higher risk of euthanasia than other sized dogs in most animal shelters in the United States. We hypothesized one way to increase the lives saved with respect to these large dogs is to keep them home when possible. In order to develop solutions to decrease relinquishment, a survey was developed to learn more about the reasons owners relinquish large dogs. The survey was administered to owners relinquishing their dogs at two large municipal facilities, one in New York City and one in Washington, D.C. There were 157 responses between the two facilities. We found both significant similarities and differences between respondents and their dogs from the two cities. We identified opportunities to potentially support future relinquishers and found that targets for interventions are likely different in each community.

  15. Modulation of heat shock transcription factor 1 as a therapeutic target for small molecule intervention in neurodegenerative disease.

    Directory of Open Access Journals (Sweden)

    Daniel W Neef

    2010-01-01

    Full Text Available Neurodegenerative diseases such as Huntington disease are devastating disorders with no therapeutic approaches to ameliorate the underlying protein misfolding defect inherent to poly-glutamine (polyQ proteins. Given the mounting evidence that elevated levels of protein chaperones suppress polyQ protein misfolding, the master regulator of protein chaperone gene transcription, HSF1, is an attractive target for small molecule intervention. We describe a humanized yeast-based high-throughput screen to identify small molecule activators of human HSF1. This screen is insensitive to previously characterized activators of the heat shock response that have undesirable proteotoxic activity or that inhibit Hsp90, the central chaperone for cellular signaling and proliferation. A molecule identified in this screen, HSF1A, is structurally distinct from other characterized small molecule human HSF1 activators, activates HSF1 in mammalian and fly cells, elevates protein chaperone expression, ameliorates protein misfolding and cell death in polyQ-expressing neuronal precursor cells and protects against cytotoxicity in a fly model of polyQ-mediated neurodegeneration. In addition, we show that HSF1A interacts with components of the TRiC/CCT complex, suggesting a potentially novel regulatory role for this complex in modulating HSF1 activity. These studies describe a novel approach for the identification of new classes of pharmacological interventions for protein misfolding that underlies devastating neurodegenerative disease.

    Research on hygiene has been relatively limited in the current era of rigorous observational studies and clinical trials. We set out to investigate the perception and practices of genital hygiene among fishermen working on the beaches along Lake Victoria, targeted for a topical male microbicide hygiene intervention. We conducted 12 focus group discussions involving fishermen (n = 130), recording the discussions in Dholuo (the local language) and transcribing them verbatim before translating into English. Transcripts were double-coded and analysed using constant comparative analysis. Despite easy access to lake water and recognition of a link that may exist between poor genital hygiene and the risk of penile infection and poor sexual relationships, few fishermen regularly washed their genitalia due to fear/embarrassment from cleaning their genitalia in public, traditional Luo beliefs such as that washing with soap would reduce the fish catch, lack of time because of their busy schedules, laziness and lack of responsibility, and excessive consumption of alcohol and illicit drugs. Hygiene practices of the fishermen were poor and could contribute to genital infections including sexually transmitted infections. Given the fishermen's poor genital hygiene practices, they may benefit from hygiene intervention, including that provided by penile microbicides, which can be applied in the privacy of their bedrooms.

  17. Identification of BIRC6 as a novel intervention target for neuroblastoma therapy

    International Nuclear Information System (INIS)

    Neuroblastoma are pediatric tumors of the sympathetic nervous system with a poor prognosis. Apoptosis is often deregulated in cancer cells, but only a few defects in apoptotic routes have been identified in neuroblastoma. Here we investigated genomic aberrations affecting genes of the intrinsic apoptotic pathway in neuroblastoma. We analyzed DNA profiling data (CGH and SNP arrays) and mRNA expression data of 31 genes of the intrinsic apoptotic pathway in a dataset of 88 neuroblastoma tumors using the R2 bioinformatic platform. BIRC6 was selected for further analysis as a tumor driving gene. Knockdown experiments were performed using BIRC6 lentiviral shRNA and phenotype responses were analyzed by Western blot and MTT-assays. In addition, DIABLO levels and interactions were investigated with immunofluorescence and co-immunoprecipitation. We observed frequent gain of the BIRC6 gene on chromosome 2, which resulted in increased mRNA expression. BIRC6 is an inhibitor of apoptosis protein (IAP), that can bind and degrade the cytoplasmic fraction of the pro-apoptotic protein DIABLO. DIABLO mRNA expression was exceptionally high in neuroblastoma but the protein was only detected in the mitochondria. Upon silencing of BIRC6 by shRNA, DIABLO protein levels increased and cells went into apoptosis. Co-immunoprecipitation confirmed direct interaction between DIABLO and BIRC6 in neuroblastoma cell lines. Our findings indicate that BIRC6 may have a potential oncogenic role in neuroblastoma by inactivating cytoplasmic DIABLO. BIRC6 inhibition may therefore provide a means for therapeutic intervention in neuroblastoma

    Full Text Available Abstract Background Neuroblastoma are pediatric tumors of the sympathetic nervous system with a poor prognosis. Apoptosis is often deregulated in cancer cells, but only a few defects in apoptotic routes have been identified in neuroblastoma. Methods Here we investigated genomic aberrations affecting genes of the intrinsic apoptotic pathway in neuroblastoma. We analyzed DNA profiling data (CGH and SNP arrays and mRNA expression data of 31 genes of the intrinsic apoptotic pathway in a dataset of 88 neuroblastoma tumors using the R2 bioinformatic platform (http://r2.amc.nl. BIRC6 was selected for further analysis as a tumor driving gene. Knockdown experiments were performed using BIRC6 lentiviral shRNA and phenotype responses were analyzed by Western blot and MTT-assays. In addition, DIABLO levels and interactions were investigated with immunofluorescence and co-immunoprecipitation. Results We observed frequent gain of the BIRC6 gene on chromosome 2, which resulted in increased mRNA expression. BIRC6 is an inhibitor of apoptosis protein (IAP, that can bind and degrade the cytoplasmic fraction of the pro-apoptotic protein DIABLO. DIABLO mRNA expression was exceptionally high in neuroblastoma but the protein was only detected in the mitochondria. Upon silencing of BIRC6 by shRNA, DIABLO protein levels increased and cells went into apoptosis. Co-immunoprecipitation confirmed direct interaction between DIABLO and BIRC6 in neuroblastoma cell lines. Conclusion Our findings indicate that BIRC6 may have a potential oncogenic role in neuroblastoma by inactivating cytoplasmic DIABLO. BIRC6 inhibition may therefore provide a means for therapeutic intervention in neuroblastoma.

  19. BRCA1 and miRNAs: An Emerging Therapeutic Target and Intervention Tool in Breast Cancer

    Full Text Available Reduced BRCA1 activity, either by germ-line mutations in inherited breast cancer or by epigenetic down-regulation in sporadic cancers,represents a key pathway in tumour development and progression. Although best known for its role in the maintenance of chromosome integrity, BRCA1 has recently been found to play a role in chromatin remodelling and transcriptional regulation, as well as in mammary epithelial stem cell differentiation or mammary stem cell fate decision. While BRCA1 potentially plays a significant role in both mammary tumour development and malignant progression, its function connection to tumor development is poorly understood. Recent studies have uncovered a new role of BRCA1 in the regulation of small (~19-25 nucleotides non-coding microRNA (miRNA expression in breast cancer cells. Several studies have also shown that aggressive breast cancers and breast cancer stem cells exhibit distinctive profiles of miRNA expression, suggesting that BRCA1 associated differential expression of miRNAs can regulate important cellular functions facilitating the maintenance of breast cancer stem cells and/or promoting breast cancer aggression. In this context, we will review recent progress in the understanding of the BRCA1 function, with emphasis on the implication of the development and progression of breast cancer via differential expression of miRNAs and discuss how these studies can improve our understanding of breast cancer pathogenesis. We will also discuss the perspectives of BRCA1 function through miRNAs and the role of miRNAs in regulating BRCA1 in breast cancer, more specifically tumor suppressor, miR-125 and oncogene, mir-155 as diagnostic and prognostic tools in clinical practice, and as new avenues for therapeutic interventions.

  20. Connexins in neurons and glia:targets for intervention in disease and injury

    2015-01-01

    Both neurons and glia throughout the central nervous system are organized into networks by gap junctions. Among glia, gap junctions facilitate metabolic homeostasis and intercellular communication. Among neurons, gap junctions form electrical synapses that function pri-marily for communication. However, in neurodegenerative states due to disease or injury gap junctions may be detrimental to survival. Electrical synapses may facilitate hyperactivity and bystander killing among neurons, while gap junction hemichannels in glia may facilitate in-lfammatory signaling and scar formation. Advances in understanding mechanisms of plasticity of electrical synapses and development of molecular therapeutics to target glial gap junctions and hemichannels offer new hope to pharmacologically limit neuronal degeneration and en-hance recovery.

    Full Text Available Abstract Plaque angiogenesis may have an important role in the development of atherosclerosis. Vasa vasorum angiogenesis and medial infiltration provides nutrients to the developing and expanding intima and therefore, may prevent cellular death and contribute to plaque growth and stabilization in early lesions. However in more advanced plaques, inflammatory cell infiltration, and concomitant production of numerous pro-angiogenic cytokines may be responsible for induction of uncontrolled neointimal microvessel proliferation resulting in production of immature and fragile neovessels similar to that seen in tumour development. These could contribute to development of an unstable haemorrhagic rupture-prone environment. Increasing evidence has suggested that the expression of intimal neovessels is directly related to the stage of plaque development, the risk of plaque rupture, and subsequently, the presence of symptomatic disease, the timing of ischemic neurological events and myocardial/cerebral infarction. Despite this, there is conflicting evidence regarding the causal relationship between neovessel expression and plaque thrombosis with some in vivo experimental models suggesting the contrary and as yet, few direct mediators of angiogenesis have been identified and associated with plaque instability in vivo. In recent years, an increasing number of angiogenic therapeutic targets have been proposed in order to facilitate modulation of neovascularization and its consequences in diseases such as cancer and macular degeneration. A complete knowledge of the mechanisms responsible for initiation of adventitial vessel proliferation, their extension into the intimal regions and possible de-novo synthesis of neovessels following differentiation of bone-marrow-derived stem cells is required in order to contemplate potential single or combinational anti-angiogenic therapies. In this review, we will examine the importance of angiogenesis in complicated plaque

    Unauthorized use of natural resources is a key threat to many protected areas. Approaches to reducing this threat include law enforcement and integrated conservation and development (ICD) projects, but for such ICDs to be targeted effectively, it is important to understand who is illegally using which natural resources and why. The nature of unauthorized behavior makes it difficult to ascertain this information through direct questioning. Bwindi Impenetrable National Park, Uganda, has many ICD projects, including authorizing some local people to use certain nontimber forest resources from the park. However, despite over 25 years of ICD, unauthorized resource use continues. We used household surveys, indirect questioning (unmatched count technique), and focus group discussions to generate profiles of authorized and unauthorized resource users and to explore motivations for unauthorized activity. Overall, unauthorized resource use was most common among people from poor households who lived closest to the park boundary and farthest from roads and trading centers. Other motivations for unauthorized resource use included crop raiding by wild animals, inequity of revenue sharing, and lack of employment, factors that created resentment among the poorest communities. In some communities, benefits obtained from ICD were reported to be the greatest deterrents against unauthorized activity, although law enforcement ranked highest overall. Despite the sensitive nature of exploring unauthorized resource use, management-relevant insights into the profiles and motivations of unauthorized resource users can be gained from a combination of survey techniques, as adopted here. To reduce unauthorized activity at Bwindi, we suggest ICD benefit the poorest people living in remote areas and near the park boundary by providing affordable alternative sources of forest products and addressing crop raiding. To prevent resentment from driving further unauthorized activity, ICDs should be

    Full Text Available Objectives To investigate changing nutritional demographics of treated HIV-1-infected patients and explore causes of obesity, particularly in women of African origin.Methods We prospectively reviewed nutritional demographics of clinic attenders at an urban European HIV clinic during four one-month periods at 3-yearly intervals (2001, 2004, 2007, and 2010 and in two consecutive whole-year reviews (2010-11 and 2011-12. Risk-factors for obesity were assessed by multiple linear regression. A sub-study of 50 HIV-positive African female patients investigated body-size/shape perception using numerical, verbal and pictorial cues. Results We found a dramatic rise in the prevalence of obesity (BMI >30 kg/m2, from 8.5% (2001 to 28% (2011-12 for all clinic attenders, of whom 86% were on antiretroviral treatment. Women of African origin were most affected, 49% being obese, with a further 32% overweight (BMI 25-30 kg/m2, in 2012. Clinical factors strongly associated with obesity included female gender, black African ethnicity, non-smoking, age and CD4 count (all P<0.001; greater duration of cART did not predict obesity. Individual weight-time trends mostly showed slow long-term progressive weight gain. Investigating body weight perception, we found that weight and adiposity were underestimated by obese subjects, who showed a greater disparity between perceived and actual adiposity (P<0.001. Obese subjects targeted more obese target ideal body shapes (P<0.01, but were less satisfied with their body shape overall (P=0.02. Conclusions Seropositive African women on antiretroviral treatment are at heightened risk of obesity. Although multifactorial, bodyweight perception represents a potential target for intervention.

    also striking gender differences in environmental information processing and cell communication pathways. Many proteins encoded by GA genes are secreted by Brugia malayi, and these encode immunomodulatory molecules such as antioxidants and host cytokine mimics. Expression of many GA genes has been recently reported to be suppressed by tetracycline, which blocks reproduction in female Brugia malayi. Our localization of GA transcripts in filarial reproductive organs supports the hypothesis that these genes encode proteins involved in reproduction. CONCLUSIONS/SIGNIFICANCE: Genome-wide expression profiling coupled with a robust bioinformatics analysis has greatly expanded our understanding of the molecular biology of reproduction in filarial nematodes. This study has highlighted key molecules and pathways associated with reproductive and other biological processes and identified numerous potential candidates for rational drug design to target reproductive processes.

  10. A model of gene-gene and gene-environment interactions and its implications for targeting environmental interventions by genotype

    Directory of Open Access Journals (Sweden)

    Wallace Helen M

    2006-10-01

    Full Text Available Abstract Background The potential public health benefits of targeting environmental interventions by genotype depend on the environmental and genetic contributions to the variance of common diseases, and the magnitude of any gene-environment interaction. In the absence of prior knowledge of all risk factors, twin, family and environmental data may help to define the potential limits of these benefits in a given population. However, a general methodology to analyze twin data is required because of the potential importance of gene-gene interactions (epistasis, gene-environment interactions, and conditions that break the 'equal environments' assumption for monozygotic and dizygotic twins. Method A new model for gene-gene and gene-environment interactions is developed that abandons the assumptions of the classical twin study, including Fisher's (1918 assumption that genes act as risk factors for common traits in a manner necessarily dominated by an additive polygenic term. Provided there are no confounders, the model can be used to implement a top-down approach to quantifying the potential utility of genetic prediction and prevention, using twin, family and environmental data. The results describe a solution space for each disease or trait, which may or may not include the classical twin study result. Each point in the solution space corresponds to a different model of genotypic risk and gene-environment interaction. Conclusion The results show that the potential for reducing the incidence of common diseases using environmental interventions targeted by genotype may be limited, except in special cases. The model also confirms that the importance of an individual's genotype in determining their risk of complex diseases tends to be exaggerated by the classical twin studies method, owing to the 'equal environments' assumption and the assumption of no gene-environment interaction. In addition, if phenotypes are genetically robust, because of epistasis

    Full Text Available Obesity in chronic hepatitis C (CHC is associated with adverse hepatic and metabolic outcomes. This prospective study evaluates the agreement between self-perceived body weight (BW status and measured body mass index (BMI category and factors associated with its underestimation in CHC. Body size perception was measured with the Contour Drawing Rating Scale. Two hundred and seventy-three patients with CHC (overweight 45%, obese 18% participated in this study. Although both overweight and obese demonstrated good body size perception, agreement between perceived BW and measured BMI categories was poor (κ=0.315, 95% CI 0.231–0.399; 33% of overweight/obese respondents considered themselves normal or underweight. Male gender (OR 2.84 and overweight (OR 2.42 or obese BMI (OR 14.19 were associated with underestimation of BW category. Targeted interventions are needed to improve body weight perception, thereby enhancing the uptake of health advice on management of excess body weight in CHC.

    Highlights: • Inhibition of TAK1 kinase activity suppresses NF-κB activation and RCC cell survival. • TAK1 inhibitors induces apoptotic cytotoxicity against RCC cells. • RCC cells with TAK1 depletion show reduced cell viability and increased apoptosis. • TAK1 and p-NF-κB are both over-expressed in human RCC tissues. • Inhibition or depletion of TAK1 enhances the activity of vinblastine sulfate. - Abstract: Renal cell carcinoma (RCC) is common renal malignancy within poor prognosis. TGF-β-activated kinase 1 (TAK1) plays vital roles in cell survival, apoptosis-resistance and carcinogenesis through regulating nuclear factor-κB (NF-κB) and other cancer-related pathways. Here we found that TAK1 inhibitors (LYTAK1, 5Z-7-oxozeanol (5Z) and NG-25) suppressed NF-κB activation and RCC cell (786-O and A489 lines) survival. TAK1 inhibitors induced apoptotic cytotoxicity against RCC cells, which was largely inhibited by the broad or specific caspase inhibitors. Further, shRNA-mediated partial depletion of TAK1 reduced 786-O cell viability whiling activating apoptosis. Significantly, TAK1 was over-expressed in human RCC tissues, and its level was correlated with phosphorylated NF-κB. Finally, kinase inhibition or genetic depletion of TAK1 enhanced the activity of vinblastine sulfate (VLB) in RCC cells. Together, these results suggest that TAK1 may be an important oncogene or an effective target for RCC intervention.

    The border between Brazil and French Guiana is a place of economic, cultural, social and sexual exchange. Female sex workers represent a high risk population for HIV in this area where sexual tourism is particularly developed. HIV testing seems to be an important element in the fight against the epidemic. Indeed, early HIV testing gives access to treatments and prevention. An HIV/AIDS knowledge, attitudes, behaviors and practices survey was conducted in 2011 among sex workers along the border between Brazil and French Guiana. A total of 213 female sex workers were interviewed. One third (31.5%) of the interviewed had never tested for HIV. Factors associated with non HIV-testing were the lack of knowledge of places where to do an HIV test, to be 30 or older, feeling at risk of HIV, not evaluating one's own risk towards HIV, and living in Oiapoque. These results clearly suggest that targeted interventions are needed to encourage and assist female sex workers to get tested regularly. PMID:26375641

  16. Fate of challenge schistosomula in the murine anti-schistosome vaccine model

    International Nuclear Information System (INIS)

    Mice exposed to irradiated cercariae of Schistosoma mansoni develop a partial resistance to subsequent parasite challenge. In this study the authors utilized histopathologic methods to investigate the fate of both the immunizing and challenge cercariae in C57BL/6J mice. After immunization by percutaneous infection, a large number of the 50 Kr irradiated organisms could be detected in tissue sections of lung. However, as early as 2 weeks after immunization, the majority of these schistosomula apparently had died, leaving residual inflammatory foci. The numbers of these foci then gradually declined during the next 4 weeks of examination. Cercarial challenge of mice vaccinated 4 weeks previously provoked an intense eosinophil-enriched inflammatory response in percutaneously exposed ear pinnae. Despite these pronounced tissue reactions, no evidence of significant parasite damage or attrition was detected in this migration site. In contrast, schistosomula arriving in the lungs of vaccinated mice produced a greater number of residual inflammatory foci than did larvae appearing in the lungs of normal mice. In addition, challenge schistosomula were cleared from the lungs of vaccinated mice at a slower rate than they were from the lungs of control mice. These observations suggest that the lung is a major site of parasite attrition for both immunizing and challenge infections in the mouse irradiated vaccine model

    Full Text Available Abstract Background Avahan, the India AIDS Initiative has been a partner supporting targeted interventions of high risk populations under India’s National AIDS Control Organisation (NACO since 2004 in the state of Maharashtra. This paper presents an assessment of the Avahan program among female sex workers (FSWs in Maharashtra, its coverage, outcomes achieved and their association with Avahan program. Methods An analytical framework based on the Avahan evaluation design was used, addressing assessment questions on program implementation, intermediate outcomes and association of outcomes with Avahan. Data from routine program monitoring, two rounds of cross-sectional Integrated Behavioural and Biological Assessments (IBBAs conducted in 2006 (Round 1- R1 and 2009 (Round 2 – R2 and quality assessments of program clinics were used. Bi-variate and multivariate analysis were conducted using the complex samples module in SPSS 15® (IBM, Somers NY. Results The Avahan program achieved coverage of over 66% of FSWs within four years of implementation. The IBBA data showed increased contact by peers in R2 compared to R1 (AOR:2.34; p=0.001. Reported condom use with clients increased in R2 and number of FSWs reporting zero unprotected sex acts increased from 76.2% (R1 to 94.6% (R2 [AOR: 5.1, p=0.001]. Significant declines were observed in prevalence of syphilis (RPR (15.8% to 10.8%; AOR:0.54; p=0.001, chlamydia (8% to 6.2%; AOR:.0.65; p=0.010 and gonorrohoea (7.4% to 3.9; AOR:.0.60; p=0.026 between R1 and R2.

    2011-09-01

    Full Text Available Abstract Background Pain is one of the most frequent problems among patients diagnosed with cancer. Despite the availability of effective pharmacological treatments, this group of patients often receives less than optimal treatment. Research into nurses' pain management highlights certain factors, such as lack of knowledge and attitudes and inadequate procedures for systematic pain assessment, as common barriers to effective pain management. However, educational interventions targeting nurses' pain management have shown promise. As cancer-related pain is also known to have a negative effect on vital aspects of the patient's life, as well as being commonly associated with problems such as sleep, fatigue, depression and anxiety, further development of knowledge within this area is warranted. Methods/design A quasi-experimental study design will be used to investigate whether the implementation of guidelines for systematic daily pain assessments following a theory-based educational intervention will result in an improvement in knowledge and attitude among nurses. A further aim is to investigate whether the intervention that targets nurses' behaviour will improve hospital patients' perception of pain. Data regarding nurses' knowledge and attitudes to pain (primary outcome, patient perception regarding pain (secondary outcome, together with socio-demographic variables, will be collected at baseline and at four weeks and 12 weeks following the intervention. Discussion Nursing care is nowadays acknowledged as an increasingly complicated activity and "nursing complexity is such that it can be seen as the quintessential complex intervention." To be able to change and improve clinical practice thus requires multiple points of attack appropriate to meet complex challenges. Consequently, we expect the theory-based intervention used in our quasi-experimental study to improve care as well as quality of life for this group of patients and we also envisage that

    Full Text Available Small trials with short term follow up suggest pharmacists' interventions targeted at healthcare professionals can improve prescribing. In comparison with clinical guidance, contemporary statin prescribing is sub-optimal and achievement of cholesterol targets falls short of accepted standards, for patients with atherosclerotic vascular disease who are at highest absolute risk and who stand to obtain greatest benefit. We hypothesised that a pharmacist-led complex intervention delivered to doctors and nurses in primary care, would improve statin prescribing and achievement of cholesterol targets for incident and prevalent patients with vascular disease, beyond one year.We allocated general practices to a 12-month Statin Outreach Support (SOS intervention or usual care. SOS was delivered by one of 11 pharmacists who had received additional training. SOS comprised academic detailing and practical support to identify patients with vascular disease who were not prescribed a statin at optimal dose or did not have cholesterol at target, followed by individualised recommendations for changes to management. The primary outcome was the proportion of patients achieving cholesterol targets. Secondary outcomes were: the proportion of patients prescribed simvastatin 40 mg with target cholesterol achieved; cholesterol levels; prescribing of simvastatin 40 mg; prescribing of any statin and the proportion of patients with cholesterol tested. Outcomes were assessed after an average of 1.7 years (range 1.4-2.2 years, and practice level simvastatin 40 mg prescribing was assessed after 10 years.We randomised 31 practices (72 General Practitioners (GPs, 40 nurses. Prior to randomisation a subset of eligible patients were identified to characterise practices; 40% had cholesterol levels below the target threshold. Improvements in data collection procedures allowed identification of all eligible patients (n = 7586 at follow up. Patients in practices allocated to SOS were

    Full Text Available Abstract Background Increasing physical activity (PA among adolescents is an important health promotion goal. PA has numerous positive health effects, but the majority of Dutch adolescents do not meet PA requirements. The present paper describes the systematic development of a theory-based computer-tailored intervention, YouRAction, which targets individual and environmental factors determining PA among adolescents. Design The intervention development was guided by the Intervention Mapping protocol, in order to define clear program objectives, theoretical methods and practical strategies, ensure systematic program planning and pilot-testing, and anticipate on implementation and evaluation. Two versions of YouRAction were developed: one that targets individual determinants and an extended version that also provides feedback on opportunities to be active in the neighbourhood. Key determinants that were targeted included: knowledge and awareness, attitudes, self-efficacy and subjective norms. The extended version also addressed perceived availability of neighbourhood PA facilities. Both versions aimed to increase levels of moderate-to-vigorous PA among adolescents. The intervention structure was based on self-regulation theory, comprising of five steps in the process of successful goal pursuit. Monitoring of PA behaviour and behavioural and normative feedback were used to increase awareness of PA behaviour; motivation was enhanced by targeting self-efficacy and attitudes, by means of various interactive strategies, such as web movies; the perceived environment was targeted by visualizing opportunities to be active in an interactive geographical map of the home environment; in the goal setting phase, the adolescents were guided in setting a goal and developing an action plan to achieve this goal; in the phase of active goal pursuit adolescents try to achieve their goal and in the evaluation phase the achievements are evaluated.

    Full Text Available BACKGROUND: A large proportion of university students show symptoms of common mental disorders, such as depression, anxiety, substance use disorders and eating disorders. Novel interventions are required that target underlying factors of multiple disorders. AIMS: To evaluate the efficacy of a transdiagnostic trait-focused web-based intervention aimed at reducing symptoms of common mental disorders in university students. METHOD: Students were recruited online (n=1047, age: M=21.8, SD=4.2 and categorised into being at high or low risk for mental disorders based on their personality traits. Participants were allocated to a cognitive-behavioural trait-focused (n=519 or a control intervention (n=528 using computerised simple randomisation. Both interventions were fully automated and delivered online (trial registration: ISRCTN14342225. Participants were blinded and outcomes were self-assessed at baseline, at 6 weeks and at 12 weeks after registration. Primary outcomes were current depression and anxiety, assessed on the Patient Health Questionnaire (PHQ9 and Generalised Anxiety Disorder Scale (GAD7. Secondary outcome measures focused on alcohol use, disordered eating, and other outcomes. RESULTS: Students at high risk were successfully identified using personality indicators and reported poorer mental health. A total of 520 students completed the 6-week follow-up and 401 students completed the 12-week follow-up. Attrition was high across intervention groups, but comparable to other web-based interventions. Mixed effects analyses revealed that at 12-week follow up the trait-focused intervention reduced depression scores by 3.58 (p<.001, 95%CI [5.19, 1.98] and anxiety scores by 2.87 (p=.018, 95%CI [1.31, 4.43] in students at high risk. In high-risk students, between group effect sizes were 0.58 (depression and 0.42 (anxiety. In addition, self-esteem was improved. No changes were observed regarding the use of alcohol or disordered eating. CONCLUSIONS

    This randomized study examined the effectiveness of a preschool stimulation program created to teach words that had been selected by considering the needs of the target population of children. Twenty-two educators and their group of at-risk preschoolers (N = 222, M age = 4.27 years) were assigned to one of two conditions: control or intervention. In the latter condition, educators had to read specifically developed storybooks to their group and conduct stimulation activities. Despite the training and support they received, educators implemented the intervention with varying degrees of fidelity. Nonetheless, intent-to-treat comparison of the two conditions indicates that children in the intervention condition learned the meaning of a much greater number of words than their peers in the control condition. In addition, efficacy subset analyses that took into account fidelity of implementation show that the greatest gains were made by children who had an educator who had implemented the intervention reliably. Strategies for scaling up the intervention and optimizing its implementation are discussed. PMID:23543358

    USE OF GIS TECHNOLOGY IN SURFACE WATER MONITORING FOR TARGETED POLICY INTERVENTION IN A MOUNTAINOUS CATCHMENT IN ROMANIA The collection of information on surface water quality is a specific activity that takes place systematically and regularly at regional and national scale, and it is important for the assessment of the water quality as well as for water management policy-making. A data base information management using a Geographical Information System (GIS) forms an important aspect of environmental management, which provides the frame for processing and visualisation of water monitoring data and information as well as for the optimisation of monitoring concepts. This paper presents an architecture performed by a GIS which provides a grafic database and attributes the nesessary measurements of the water quality to different sections of the mountainous catchment of the Suceava river in the north of Romania. With this approach the location of the water sampling points can be optimised in terms of the selection and setting of the river sections. To facilitate the setting of the sampling locations in the various sections of water sampling in the river, the presented GIS system provides to the user different information layers with combined or isolated data according to the objectives. In the frame of the research were created 5 layers of information in the basin under study, underlying the determination of a new information layer, namely the "Hydrografic Network Graded to Hydrographic Sections". Practically, in the studied basin were established 8 sections for water sampling locations, and the water quality characterization was done by the consideration of 15 quality indicators. The GIS system presented in this research is a valuable, useful and adaptable to land use changes data base that can be exploited by any number of combinations, its capabilities justify it's role as "tool to support decision making." With this characteristics it supports the policy-making of

    Full Text Available Abstract Background Children of substance-abusing parents are at risk for developing psychosocial development problems. In Germany it is estimated that approx. 2.65 million children are affected by parental substance abuse or dependence. Only ten percent of them receive treatment when parents are treated. To date, no evaluated programme for children from substance-affected families exists in Germany. The study described in this protocol is designed to test the effectiveness of the group programme TRAMPOLINE for children aged 8-12 years with at least one substance-abusing or -dependent caregiver. The intervention is specifically geared to issues and needs of children from substance-affected families. Methods/Design The effectiveness of the manualised nine-session group programme TRAMPOLINE is tested among N = 218 children from substance-affected families in a multicentre randomised controlled trial. Outpatient counselling facilities across the nation from different settings (rural/urban, Northern/Southern/Eastern/Western regions of the country will deliver the interventions, as they hold the primary access to the target group in Germany. The control condition is a group programme with the same duration that is not addiction-specific. We expect that participants in the intervention condition will show a significant improvement in the use of adaptive coping strategies (in general and within the family compared to the control condition as a direct result of the intervention. Data is collected shortly before and after as well as six months after the intervention. Discussion In Germany, the study presented here is the first to develop and evaluate a programme for children of substance-abusing parents. Limitations and strengths are discussed with a special focus on recruitment challenges as they appear to be the most potent threat to feasibility in the difficult-to-access target group at hand (Trial registration: ISRCTN81470784.

    The risk of dying suddenly and unexpectedly is increased 24- to 28-fold among young people with epilepsy compared to the general population, but the incidence of sudden unexpected death in epilepsy (SUDEP) varies markedly depending on the epilepsy population. This article first reviews risk factors and biomarkers for SUDEP with the overall aim of enabling identification of epilepsy populations with different risk levels as a background for a discussion of possible intervention strategies. The by far most important clinical risk factor is frequency of generalized tonic-clonic seizures (GTCS), but nocturnal seizures, early age at onset, and long duration of epilepsy have been identified as additional risk factors. Lack of antiepileptic drug (AED) treatment or, in the context of clinical trials, adjunctive placebo versus active treatment is associated with increased risks. Despite considerable research, reliable electrophysiologic (electrocardiography [ECG] or electroencephalography [EEG]) biomarkers of SUDEP risk remain to be established. This is an important limitation for prevention strategies and intervention studies. There is a lack of biomarkers for SUDEP, and until validated biomarkers are found, the endpoint of interventions to prevent SUDEP must be SUDEP itself. These interventions, be they pharmacologic, seizure-detection devices, or nocturnal supervision, require large numbers. Possible methods for assessing prevention measures include public health community interventions, self-management, and more traditional (and much more expensive) randomized clinical trials.

    Full Text Available Abstract Background Frail elderly people need an integrated and coordinated care. The two-armed study "Continuum of care for frail elderly people" is a multi-professional and multidimensional intervention for frail community-dwelling elderly people. It was designed to evaluate whether the intervention programme for frail elderly people can reduce the number of visits to hospital, increase satisfaction with health and social care and maintain functional abilities. The implementation process is explored and analysed along with the intervention. In this paper we present the study design, the intervention and the outcome measures as well as the baseline characteristics of the study participants. Methods/design The study is a randomised two-armed controlled trial with follow ups at 3, 6 and 12 months. The study group includes elderly people who sought care at the emergency ward and discharged to their own homes in the community. Inclusion criteria were 80 years and older or 65 to 79 years with at least one chronic disease and dependent in at least one activity of daily living. Exclusion criteria were acute severely illness with an immediate need of the assessment and treatment by a physician, severe cognitive impairment and palliative care. The intention was that the study group should comprise a representative sample of frail elderly people at a high risk of future health care consumption. The intervention includes an early geriatric assessment, early family support, a case manager in the community with a multi-professional team and the involvement of the elderly people and their relatives in the planning process. Discussion The design of the study, the randomisation procedure and the protocol meetings were intended to ensure the quality of the study. The implementation of the intervention programme is followed and analysed throughout the whole study, which enables us to generate knowledge on the process of implementing complex interventions. The

    While much progress has been made in developing drugs against a few prominent viruses such as HIV, few examples exist for emerging infectious agents. In some cases broad spectrum anti-viral drugs, such as ribavirin, are effective, but for some groups of viruses, these show little efficacy in animal models. Traditional methods focus on screening small molecule libraries to identify drugs that target virus factors, with the intention that side-effects to the host can be minimized. However, this greatly limits potential drug targets and virus genes can rapidly mutate to avoid drug action. Recent advances in siRNA gene targeting technologies have provided a powerful tool to specifically target and suppress the expression of cell genes. Since viruses are completely dependent upon host cell proteins for propagation, siRNA screening promises to reveal novel cell proteins and signaling pathways that may be viable targets for drug therapy regimens. Here we used an siRNA screening approach to identify gene products that play critical roles in Ebola virus infection. By gene cluster analysis, proteins in phosphatidylinositol-3-kinase and calcium/calmodulin kinase related networks were identified as important for Zaire Ebola virus infection and prioritized for further evaluation. Key roles of each were confirmed by testing available drugs specific for members of each pathway. Interestingly, both sets of proteins are also important in cancer and subject to intense investigation. Thus development of new drugs against these cancer targets may also prove useful in combating Ebola virus. PMID:20930947

    Horodynski Mildred A

    2011-11-01

    Full Text Available Abstract Background Poor feeding practices during infancy contribute to obesity risk. As infants transition from human milk and/or formula-based diets to solid foods, these practices interfere with infant feeding self-regulation and healthy growth patterns. Compared with other socioeconomic groups, lower-income mothers are more likely to experience difficulty feeding their infants. This may include misinterpreting feeding cues and using less-than-optimal feeding styles and practices, such as pressuring infants during mealtimes and prematurely introducing solid food and sweetened beverages. The Healthy Babies trial aims to determine the efficacy of a community-based randomized controlled trial of an in-home intervention with economically and educationally disadvantaged mother-infant dyads. The educational intervention is being conducted during the infant's first 6 months of life to promote healthy transition to solids during their first year and is based on the theory of planned behavior. Methods/Design We will describe our study protocol for a multisite randomized control trial being conducted in Colorado and Michigan with an anticipated sample of 372 economically and educationally disadvantaged African American, Hispanic, and Caucasian mothers with infants. Participants are being recruited by county community agency staff. Participants are randomly assigned to the intervention or the control group. The intervention consists of six in-home visits by a trained paraprofessional instructor followed by three reinforcement telephone contacts when the baby is 6, 8, and 10 months old. Main maternal outcomes include a maternal responsiveness, b feeding style, and c feeding practices. Main infant outcome is infant growth pattern. All measures occur at baseline and when the infant is 6 and 12 months old. Discussion If this project is successful, the expected outcomes will address whether the home-based early nutrition education intervention is effective

The aim of this paper is to describe the 3-phase development of the Feeding Dynamics Intervention (FDI, an acceptability and feasibility study on implementing the feeding dynamic roles (Study 1, development of the FDI content (Study 2, and a pilot study on use of the 6-lesson FDI to promote behaviors consistent with a feeding dynamic approach (Study 3. Sample population was mothers with young children, 2–5 years old. An effect size (Hedges’ g greater than 0.20 was seen in more than half (57% of maternal feeding behaviors, with the largest effect sizes (Hedges’ g≥0.8 occurring with behaviors that represent the mother adopting her roles of determining what food is served, not using food as a reward, and not controlling her child’s intake. There was a significant decline in Pressure to Eat behaviors (2.9 versus 2.2, p<0.01 and Monitoring (4.1 versus 3.5, p<0.001. The FDI emerged as an acceptable and implementable intervention. Future studies need to investigate effects of the FDI on the child’s eating behaviors, self-regulation of energy intake, and anthropometrics.

    Full Text Available Abstract Background Public priorities for improvement often differ from those of clinicians and managers. Public involvement has been proposed as a way to bridge the gap between professional and public clinical care priorities but has not been studied in the context of quality-indicator choice. Our objective is to assess the feasibility and impact of public involvement on quality-indicator choice and agreement with public priorities. Methods We will conduct a cluster randomised controlled trial comparing quality-indicator prioritisation with and without public involvement. In preparation for the trial, we developed a 'menu' of quality indicators, based on a systematic review of existing validated indicator sets. Participants (public representatives, clinicians, and managers will be recruited from six participating sites. In intervention sites, public representatives will be involved through direct participation (public representatives, clinicians, and managers will deliberate together to agree on quality-indicator choice and use and consultation (individual public recommendations for improvement will be collected and presented to decision makers. In control sites, only clinicians and managers will take part in the prioritisation process. Data on quality-indicator choice and intended use will be collected. Our primary outcome will compare quality-indicator choice and agreement with public priorities between intervention and control groups. A process evaluation based on direct observation, videorecording, and participants' assessment will be conducted to help explain the study's results. The marginal cost of public involvement will also be assessed. Discussion We identified 801 quality indicators that met our inclusion criteria. An expert panel agreed on a final set of 37 items containing validated quality indicators relevant for chronic disease prevention and management in primary care. We pilot tested our public-involvement intervention with 27

In this study, we used the framework of the continuum of maternal and child care to evaluate the impact of interventions in Bauchi State focused on improved maternal and child health, and to ascertain progress towards the achievement of Millennium Development Goals (MDGs 4 and 5.At baseline (2012 and then at follow-up (2013, we randomly sampled 340 households from 19 random locations in each of the 20 Local Government Areas (LGA of Bauchi State in Northern Nigeria, using the Lot Quality Assurance Sampling (LQAS technique. Women residents in the households were interviewed about their own health and that of their children. Estimated LGA coverage of maternal and child health indicators were aggregated across the State. These values were then compared to the national figures, and the differences from 2012 to 2014 were calculated.For several of the indicators, a modest improvement from baseline was found. However, the indicators in the continuum of care neither reached the national average nor attained the 90% globally recommended coverage level. The majority of the LGA surveyed were classifiable as high priority, thus requiring intensified efforts and programmatic scale up.Intensive scale-up of programs and interventions is needed in Bauchi State, Northern Nigeria, to accelerate, consolidate and sustain the modest but significant achievements in the continuum of care, if MDGs 4 and 5 are to be achieved by the end of 2015. The intentional focus of LGAs as the unit of intervention ought to be considered a condition precedent for future investments. Priority should be given to the re-allocating resources to program areas and regions where coverage has been low. Finally, systematic

Women residents in the households were interviewed about their own health and that of their children. Estimated LGA coverage of maternal and child health indicators were aggregated across the State. These values were then compared to the national figures, and the differences from 2012 to 2014 were calculated. Results For several of the indicators, a modest improvement from baseline was found. However, the indicators in the continuum of care neither reached the national average nor attained the 90% globally recommended coverage level. The majority of the LGA surveyed were classifiable as high priority, thus requiring intensified efforts and programmatic scale up. Conclusions Intensive scale-up of programs and interventions is needed in Bauchi State, Northern Nigeria, to accelerate, consolidate and sustain the modest but significant achievements in the continuum of care, if MDGs 4 and 5 are to be achieved by the end of 2015. The intentional focus of LGAs as the unit of intervention ought to be considered a condition precedent for future investments. Priority should be given to the re-allocating resources to program areas and regions where coverage has been

    The Fc receptor I for IgA (FcαRI) down-regulates humoral immune responses and modulates the risk of autoimmunity. This study aimed to investigate whether FcαRI targeting can affect progression of pristine-induced lupus nephritis. In the first experiment (early intervention), four groups of animals were evaluated: untreated FcαRI/FcRγ transgenic (Tg) mice and Tg mice administered control antibody (Ctr Fab), saline and anti-FcαRI Fab [macrophage inflammatory protein (MIP)-8a], respectively, three times a week for 29 weeks, after being injected once intraperitoneally with 0·5 ml pristane. In the second experiment, antibody injection started after the onset of nephritis and was carried out for 2 months, with similar groups as described above. MIP-8a improved proteinuria, decreased the amounts of glomerular injury markers, serum interleukin (IL)-6, IL-1 and monocyte chemoattractant protein (MCP)-1, and F4/80 macrophages in the interstitium and glomeruli, in both experiments. When MIP-8a was used as early intervention, a decrease in mouse serum anti-nuclear antibody (ANA) titres and reduced deposition of immunoglobulins in glomeruli were observed. This effect was associated with reduced serum titres of immunoglobulin (Ig)G2a but not IgG1, IgG2b and IgG3. Furthermore, pathological analysis showed lower glomerular activity index and less fibronectin in MIP-8a treated mice. This study suggests that FcαRI targeting could halt disease progression and lupus activation by selective inhibition of cytokine production, leucocyte recruitment and renal inflammation. Our findings provide a basis for the use of FcαRI as a molecular target for the treatment of lupus. PMID:25907714

    Background US veterans report lower health-related quality of life (HRQoL) relative to the general population. Identifying behavioral factors related to HRQoL that are malleable to change may inform interventions to improve well-being in this vulnerable group. Purpose The current study sought to characterize HRQoL in a largely male sample of veterans in addictions treatment, both in relation to US norms and in association with five recommended health behavior practices: regularly exercising, managing stress, having good sleep hygiene, consuming fruits and vegetables, and being tobacco free. Methods We assessed HRQoL with 250 veterans in addictions treatment (96 % male, mean age 53, range 24–77) using scales from four validated measures. Data reduction methods identified two principal components reflecting physical and mental HRQoL. Model testing of HRQoL associations with health behaviors adjusted for relevant demographic and treatment-related covariates. Results Compared to US norms, the sample had lower HRQoL scores. Better psychological HRQoL was associated with higher subjective social standing, absence of pain or trauma, lower alcohol severity, and monotonically with the sum of health behaviors (all p management, and sleep hygiene. Regular exercise also related to better physical HRQoL. The models explained >40 % of the variance in HRQoL. Conclusions Exercise, sleep hygiene, and stress management are strongly associated with HRQoL among veterans in addictions treatment. Future research is needed to test the effect of interventions for improving well-being in this high-risk group. PMID:26886926

    An engineering evaluation has been initiated to investigate conceptual engineering methods for implementing a viable gas shield strategy in the Fusion Test Facility (FTF) target chamber. The employment of a low pressure noble gas in the target chamber to thermalize energetic helium ions prior to interaction with the wall could dramatically increase the useful life of the first wall in the FTF reactor1. For the purpose of providing flexibility, two target chamber configurations are addressed: a five meter radius sphere and a ten meter radius sphere. Experimental studies at Nike have indicated that a low pressure, ambient gas resident in the target chamber during laser pulsing does not appear to impair the ability of laser light from illuminating targets2. In addition, current investigations into delivering, maintaining, and processing low pressure gas appear to be viable with slight modification to current pumping and plasma exhaust processing technologies3,4. Employment of a gas fill solution for protecting the dry wall target chamber in the FTF may reduce, or possibly eliminate the need for other attenuating technologies designed for keeping He ions from implanting in first wall structures and components. The gas fill concept appears to provide an effective means of extending the life of the first wall while employing mostly commercial off the shelf (COTS) technologies. Although a gas fill configuration may provide a methodology for attenuating damage inflicted on chamber surfaces, issues associated with target injection need to be further analyzed to ensure that the gas fill concept is viable in the integrated FTF design5. In the proposed system, the ambient noble gas is heated via the energetic helium ions produced by target detonation. The gas is subsequently cooled by the chamber wall to approximately 800oC, removed from the chamber, and processed by the chamber gas processing system (CGPS). In an optimized scenario of the above stated concept, the chamber

    While much progress has been made in developing drugs against a few prominent viruses such as HIV, few examples exist for emerging infectious agents. In some cases broad spectrum anti-viral drugs, such as ribavirin, are effective, but for some groups of viruses, these show little efficacy in animal models. Traditional methods focus on screening small molecule libraries to identify drugs that target virus factors, with the intention that side-effects to the host can be minimized. However, this...

    It has been several years since the function of the non-neuronal cholinergic system was independently reported in cardiomyocytes by several research groups. Although these findings initially seemed to be negligible and insignificant, extraordinary findings about cardiomyocytes were subsequently reported in studies involving the knockdown of the non-neuronal cholinergic system. These studies provide the evidence that this system may be indispensable for maintaining principal cardiac functions. Despite the absence of an appropriate and reliable technology to detect cellular ACh in real time in cardiomyocytes, studies of this system have progressed, albeit very slowly, to gradually consolidate the significance of this system. Based on the many significant findings regarding this system, these will be critical to develop adjunctive intervention therapy against cardiovascular diseases, including peripheral artery disease and heart failure. In this study, previous studies focusing on the non-neuronal cholinergic system are reviewed along with our studies, both indicating the biologically significant roles of the cardiac non-neuronal acetylcholine system from a clinical perspective.

    The highly conserved abundant nuclear protein poly(ADP-ribose)polymerase1 (PARP1) functions at the center of cellular stress response and is mainly implied in DNA damage repair mechanism. Apart from its involvement in DNA damage repair, it does sway multiple vital cellular processes such as cell death pathways, cell aging, insulator function, chromatin modification, transcription and mitotic apparatus function. Since brain is the principal organ vulnerable to oxidative stress and inflammatory responses, upon stress encounters robust DNA damage can occur and intense PARP1 activation may result that will lead to various CNS diseases. In the context of soaring interest towards PARP1 as a therapeutic target for newer pharmacological interventions, here in the present review, we are attempting to give a silhouette of the role of PARP1 in the neurological diseases and the potential of its inhibitors to enter clinical translation, along with its structural and functional aspects.

    In response to a climate of constant change and increasing demand for services, general practice in the UK has undergone significant modification over the last 10 years. It has become a multi-disciplinary organisation encouraged by funding bodies to plan for service delivery using a more structured team based approach. In Tayside in 1996, practices were charged with producing formal Practice Development Plans (PDPs) which would focus on priority areas aligned with the Health Boards own strategic plan--those were teamwork, information management and technology, and clinical service delivery. The University of Dundee's Department of General Practice successfully applied for funding to develop ways of facilitating practices so that they could a) identify their own development priorities, and b) plan and implement action and learning to see these priorities through. Using action research methodology, the project attempted to create a climate for change, provide support and training to see the changes implemented, and ensure commitment to the changes from all members of the practice team. The Facilitator adopted a flexible style varying her role between expert, guide and support. Analysis of progress made by different practices, coupled with the Facilitator's in depth knowledge of them, suggested the importance of certain key aspects of practice organisation and culture. A practice characterisation model identified practices which were stable, currently coping, proactive and ready to face the challenge of change as best placed to engage in a full scale development programme. Other profiles suggested a range of alternative interventions as more likely to be acceptable and productive. PMID:11499046

    Cancer-associated fibroblasts (CAFs) constitute an important part of the tumor microenvironment and promote invasion via paracrine functions and physical impact on the tumor. Although the importance of including CAFs into three-dimensional (3D) cell cultures has been acknowledged, computational support for quantitative live-cell measurements of complex cell cultures has been lacking. Here, we have developed a novel automated pipeline to model tumor-stroma interplay, track motility and quantify morphological changes of 3D co-cultures, in real-time live-cell settings. The platform consists of microtissues from prostate cancer cells, combined with CAFs in extracellular matrix that allows biochemical perturbation. Tracking of fibroblast dynamics revealed that CAFs guided the way for tumor cells to invade and increased the growth and invasiveness of tumor organoids. We utilized the platform to determine the efficacy of inhibitors in prostate cancer and the associated tumor microenvironment as a functional unit. Interestingly, certain inhibitors selectively disrupted tumor-CAF interactions, e.g. focal adhesion kinase (FAK) inhibitors specifically blocked tumor growth and invasion concurrently with fibroblast spreading and motility. This complex phenotype was not detected in other standard in vitro models. These results highlight the advantage of our approach, which recapitulates tumor histology and can significantly improve cancer target validation in vitro. PMID:26375443

DNA damage is also therapeutically induced for cancer treatment with the aim to eliminate tumor cells. However, the effectiveness of radio- and chemotherapy is strongly hampered by tumor cell resistance. A major reason for radio- and chemotherapeutic resistances is the simultaneous activation of cell survival pathways resulting in the activation of the transcription factor nuclear factor-kappa B (NF-κB. Here, we present a Boolean network model of the NF-κB signal transduction induced by genotoxic stress in epithelial cells. For the representation and analysis of the model, we used the formalism of logical interaction hypergraphs. Model reconstruction was based on a careful meta-analysis of published data. By calculating minimal intervention sets, we identified p53-induced protein with a death domain (PIDD, receptor-interacting protein 1 (RIP1, and protein inhibitor of activated STAT y (PIASy as putative therapeutic targets to abrogate NF-κB activation resulting in apoptosis. Targeting these structures therapeutically may potentiate the effectiveness of radio- and chemotherapy. Thus, the presented model allows a better understanding of the signal transduction in tumor cells and provides candidates as new therapeutic target structures.Keywords: apoptosis, Boolean network, cancer therapy, DNA-damage response, NF-κB

    Androgen deprivation therapy leads to a number of adverse effects including deterioration of the musculoskeletal system and increased risk factors for cardiovascular and metabolic complications. The purpose of this study is to determine the effects, efficacy, retention and compliance of a physical exercise intervention in a large established cohort of prostate cancer patients from the Randomised Androgen Deprivation and Radiotherapy (RADAR) study. Specifically, we aim to compare short- and long-term effects of a prostate cancer-specific supervised exercise program to a standard public health physical activity strategy utilizing printed resources on cardiovascular and metabolic risk factors. Our primary outcomes are cardiorespiratory capacity, abdominal obesity, and lipid and glycemic control, while secondary outcomes include self-reported physical activity, quality of life and psychological distress. Multi-site randomized controlled trial of 370 men from the RADAR study cohort undergoing treatment or previously treated for prostate cancer involving androgen deprivation therapy in the cities of Perth and Newcastle (Australia), and Wellington (New Zealand). Participants will be randomized to (1) supervised resistance/aerobic exercise or (2) printed material comprising general physical activity recommendations. Participants will then undergo progressive training for 6 months. Measurements for primary and secondary endpoints will take place at baseline, 6 months (end of intervention), and at 6 months follow-up. This study uses a large existent cohort of patients and will generate valuable information as to the continuing effects of exercise specifically targeting cardiovascular function and disease risk, insulin metabolism, abdominal obesity, physical function, quality of life and psychological distress. We expect dissemination of the knowledge gained from this project to reduce risk factors for the development of co-morbid diseases commonly associated with androgen

    Full Text Available Abstract Background The major aim of this study was to investigate whether maternal risk factors associated with socioeconomic status and small for gestational age (SGA might be viable targets of interventions to reduce differential risk of SGA by socioeconomic status (socioeconomic SGA inequality in the metropolitan area of Vancouver, Canada. Methods This study included 59,039 live, singleton births in the Vancouver Census Metropolitan Area (Vancouver from January 1, 2006 to September 17, 2009. To identify an indicator of socioeconomic SGA inequality, we used hierarchical logistic regression to model SGA by area-level variables from the Canadian census. We then modelled SGA by area-level average income plus established maternal risk factors for SGA and calculated population attributable SGA risk percentages (PAR% for each variable. Associations of maternal risk factors for SGA with average income were investigated to identify those that might contribute to SGA inequality. Finally, we estimated crude reductions in the percentage and absolute differences in SGA risks between highest and lowest average income quintiles that would result if interventions on maternal risk factors successfully equalized them across income levels or eliminated them altogether. Results Average income produced the most linear and statistically significant indicator of socioeconomic SGA inequality with 8.9% prevalence of SGA in the lowest income quintile compared to 5.6% in the highest. The adjusted PAR% of SGA for variables were: bottom four quintiles of height (51%, first birth (32%, bottom four quintiles of average income (14%, oligohydramnios (7%, underweight or hypertension, (6% each, smoking (3% and placental disorder (1%. Shorter height, underweight and smoking during pregnancy had higher prevalence in lower income groups. Crude models assuming equalization of risk factors across income levels or elimination altogether indicated little potential change in relative

    Full Text Available Abstract Background Several studies suggest that the number of risk factors rather than their nature is key to mental health disorders in childhood. Method and design The objective of this multicentre randomized controlled parallel trial (PROBE methodology is to assess the impact in a multi-risk French urban sample of a home-visiting program targeting child mental health and its major determinants. This paper describes the protocol of this study. In the study, pregnant women were eligible if they were: living in the intervention area; able to speak French, less than 26 years old; having their first child; less than 27 weeks of amenorrhea; and if at least one of the following criteria were true: less than twelve years of education, intending to bring up their child without the presence of the child’s father, and 3 low income. Participants were randomized into either the intervention or the control group. All had access to usual care in mother-child centres and community mental health services free of charge in every neighbourhood. Psychologists conducted all home visits, which were planned on a weekly basis from the 7th month of pregnancy and progressively decreasing in frequency until the child’s second birthday. Principle outcome measures included child mental health at 24 months and two major mediating variables for infant mental health: postnatal maternal depression and the quality of the caring environment. A total of 440 families were recruited, of which a subsample of 120 families received specific attachment and caregiver behaviour assessment. Assessment was conducted by an independent assessment team during home visits and, for the attachment study, in a specifically created Attachment Assessment laboratory. Discussion The CAPEDP study is the first large-scale randomised, controlled infant mental health promotion programme to take place in France. A major specificity of the program was that all home visits were conducted by

    Full Text Available Abstract Background With increasing age and longevity, the rising number of frail elders with complex and numerous health-related needs demands a coordinated health care delivery system integrating cure, care and welfare. Studies on the effectiveness of such comprehensive chronic care models targeting frail elders show inconclusive results. The CareWell-primary care program is a complex intervention targeting community-dwelling frail elderly people, that aims to prevent functional decline, improve quality of life, and reduce or postpone hospital and nursing home admissions of community dwelling frail elderly. Methods/design The CareWell-primary care study includes a (cost- effectiveness study and a comprehensive process evaluation. In a one-year pragmatic, cluster controlled trial, six general practices are non-randomly recruited to adopt the CareWell-primary care program and six control practices will deliver ‘care as usual’. Each practice includes a random sample of fifty frail elders aged 70 years or above in the cost-effectiveness study. A sample of patients and informal caregivers and all health care professionals participating in the CareWell-primary care program are included in the process evaluation. In the cost-effectiveness study, the primary outcome is the level of functional abilities as measured with the Katz-15 index. Hierarchical mixed-effects regression models / multilevel modeling approach will be used, since the study participants are nested within the general practices. Furthermore, incremental cost-effectiveness ratios will be calculated as costs per QALY gained and as costs weighed against functional abilities. In the process evaluation, mixed methods will be used to provide insight in the implementation degree of the program, patients’ and professionals’ approval of the program, and the barriers and facilitators to implementation.

    Resistance of mice to challenge infections of Schistosoma mansoni was evaluated before and after elimination of their primary, established S. mansoni infections with the chemotherapeutic drug praziquantel. Mice treated after either 10 or 20 weeks of primary infection were challenged 6 or 10 weeks after treatment. Mice infected for for 10 weeks prior to treatment expressed progressively less resistance 6 and 10 weeks after treatment. By 10 weeks after treatment significant levels of protection were no longer observed. Resistance waned more slowly if mice were treated 20 weeks after infection, and there was still significant expression of resistance to challenge 10 weeks after treatment. A separate set of experiments evaluated the use of highly irradiated cercariae as a vaccine in mice that had been previously infected with S. mansoni and cured with praziquantel. It was observed that effective immunizations were possible in previously infected mice. These studies demonstrate that established resistance waned after treatment and the rate of loss of protection was dependent upon the duration of infection prior to treatment. Furthermore, the irradiated cercarial vaccine studies indicate that in the murine model induction of immunological resistance was feasible following chemotherapeutic treatment of infected populations.

    Longitudinal clinical investigations and biological measurements have determined not only progressive brain volumetric and functional changes especially around the onset of psychosis but also the abnormality of developmental pathways based on gene-environment interaction model. However, these studies have contributed little to clinical decisions on their diagnosis and therapeutic choices because of subtle differences between patients and healthy controls. A multi-modal approach may resolve this limitation and is favorable to explore the pathophysiology of psychosis. The integrative neuroimaging studies for schizophrenia targeting early intervention and prevention (IN-STEP) is a research project aimed at exploring the pathophysiological features of the onset of psychosis and investigating possible predictive biomarkers for the clinical treatment of psychosis. Since 2008, we have adopted blood sampling, neurocognitive batteries, neurophysiological assessment, structural imaging, and functional imaging longitudinally for help-seeking ultra-high-risk (UHR) individuals and patients with first-episode psychosis (FEP). Here, we intend to introduce the IN-STEP research study protocol and present preliminary clinical findings. Thirty-seven UHR individuals and 30 patients with FEP participated in this study. Six months later, there was no difference in objective and subjective scores between the groups, which suggests that young people having symptoms and functional deficits should be cared for regardless of their history of psychosis according to their clinical stages. The rate of transition to psychosis was 7.1%, 8.0%, and 35.3% (at 6, 12, and 24months, respectively). Through this research project, we expect to clarify the pathophysiological features around the onset of psychosis and improve the prognosis of psychosis through clinical application. PMID:23219075

    Full Text Available Abstract Background The prevalence of heavy drinking among college students and its associated health related consequences highlights an urgent need for alcohol prevention programs targeting 18 to 24 year olds. Nevertheless, current alcohol prevention programs in the Netherlands pay surprisingly little attention to the drinking patterns of this specific age group. The study described in this protocol will test the effectiveness of a web-based brief alcohol intervention that is aimed at reducing alcohol use among heavy drinking college students aged 18 to 24 years old. Methods/Design The effectiveness of the What Do You Drink web-based brief alcohol intervention will be tested among 908 heavy drinking college students in a two-arm parallel group randomized controlled trial. Participants will be allocated at random to either the experimental (N = 454: web-based brief alcohol intervention or control condition (N = 454: no intervention. The primary outcome measure will be the percentage of participants who drink within the normative limits of the Dutch National Health Council for low-risk drinking. These limits specify that, for heavy alcohol use, the mean consumption cannot exceed 14 or 21 glasses of standard alcohol units per week for females and males, respectively, while for binge drinking, the consumption cannot exceed five or more glasses of standard alcohol units on one drinking occasion at least once per week within one month and six months after the intervention. Reductions in mean weekly alcohol consumption and frequency of binge drinking are also primary outcome measures. Weekly Ecological Momentary Assessment will measure alcohol-related cognitions, that is, attitudes, self-efficacy, subjective norms and alcohol expectancies, which will be included as the secondary outcome measures. Discussion This study protocol describes the two-arm parallel group randomized controlled trial developed to evaluate the effectiveness of a web-based brief

    2016-01-01

    Background Mobile phone apps are increasingly used to deliver health interventions, which provide the opportunity to present health information via different communication modes. However, scientific evidence regarding the effects of such health apps is scarce. Objective In a randomized controlled trial, we tested the efficacy of a 6-month intervention delivered via a mobile phone app that communicated either textual or auditory tailored health information aimed at stimulating fruit and vegetable intake. A control condition in which no health information was given was added. Perceived own health and health literacy were included as moderators to assess for which groups the interventions could possibly lead to health behavior change. Methods After downloading the mobile phone app, respondents were exposed monthly to either text-based or audio-based tailored health information and feedback over a period of 6 months via the mobile phone app. In addition, respondents in the control condition only completed the baseline and posttest measures. Within a community sample (online recruitment), self-reported fruit and vegetable intake at 6-month follow-up was our primary outcome measure. Results In total, 146 respondents (ranging from 40 to 58 per condition) completed the study (attrition rate 55%). A significant main effect of condition was found on fruit intake (P=.049, partial η2=0.04). A higher fruit intake was found after exposure to the auditory information, especially in recipients with a poor perceived own health (P=.003, partial η2=0.08). In addition, health literacy moderated the effect of condition on vegetable intake 6 months later (Pbehaviors. Based on our results, it seems worthwhile to investigate additional ways to increase fruit and vegetable intake in recipients with low health literacy.

    Background.  Tuberculosis (TB) control is a public health priority with 3 million cases unrecognized by the public health system each year. We assessed the impact of improved TB diagnostics and on-site training on TB case detection and treatment outcomes in rural healthcare facilities. Methods.  Fluorescence microscopy, Xpert MTB/RIF, and on-site training were introduced at 10 healthcare facilities. Using quasi-experimental methods, these 10 intervention healthcare facilities were compared with 2 controls and their own performance the previous year. Results.  From January to October 2012, 186 357 and 32 886 outpatients were seen in the 10 intervention and 2 control facilities, respectively. The intervention facilities had a 52.04% higher proportion of presumptive TB cases with a sputum examination (odds ratio [OR] = 12.65; 95% confidence interval [CI], 5.60-28.55). After adjusting for age group and gender, the proportion of smear-positive patients initiated on treatment was 37.76% higher in the intervention than in the control facilities (adjusted OR [AOR], 7.59; 95% CI, 2.19-26.33). After adjusting for the factors above, as well as human immunodeficiency virus and TB retreatment status, the proportion of TB cases who completed treatment was 29.16% higher (AOR, 4.89; 95% CI, 2.24-10.67) and the proportion of TB cases who were lost to follow-up was 66.98% lower (AOR, 0.04; 95% CI, 0.01-0.09). When compared with baseline performance, the intervention facilities had a significantly higher proportion of presumptive TB cases with a sputum examination (64.70% vs 3.44%; OR, 23.95; 95% CI, 12.96-44.25), and these facilities started 56.25% more smear-positive TB cases on treatment during the project period (AOR, 15.36; 95% CI, 6.57-35.91). Conclusions.  Optimizing the existing healthcare workforce through a bundled diagnostics and on-site training intervention for nonphysician healthcare workers will rapidly improve TB case detection and outcomes towards global

    With increased migration, female genital mutilation (FGM) also referred to as female circumcision or female genital cutting is no longer restricted to Africa, the Middle East, and Asia. The European Parliament estimates that up to half a million women living in the EU have been subjected to FGM, with a further 180,000 at risk. Aware of the limited success of campaigns addressing FGM, the World Health Organization recommended a behavioural change approach be implemented in order to end FGM. To date, however, little progress has been made in adopting a behaviour change approach in strategies aimed at ending FGM. Based on research undertaken as part of the EU's Daphne III programme, which researched FGM intervention programmes linked to African communities in the EU (REPLACE), this paper argues that behaviour change has not been implemented due to a lack of understanding relating to the application of the two broad categories of behaviour change approach: individualistic decision-theoretic and community-change game-theoretic approaches, and how they may be integrated to aid our understanding and the development of future intervention strategies. We therefore discuss how these can be integrated and implemented using community-based participatory action research methods with affected communities. PMID:23983698

  2. Options for the deduction of target and intervention values for radon precursors of the 238U- and 232Th-series in soils

    International Nuclear Information System (INIS)

    Radiation protection policy in the Netherlands applies to human activities in which ionizing radiation presents a hazard, not to naturally occurring sources of radiation. The risk levels (maximum permissible risk and negligible risk) apply to sources of radiation that cause an additional risk. Translation of these levels into practical environmental quality objectives therefore implies that both the extent and the origin of the risk are determined. The distinction between the natural and the additional radiation dose is of particular interest. In this report various possibilities are described for measuring, explaining and predicting the naturally occurring concentrations of the precursors of the element radon in the two radioactive decay series starting with 238U and 232Th. Several methods are given that may be used to derive environmental quality objectives for the soil with respect to these radionuclides. These environmental quality objectives are an important basis for among other things the soil sanitation policy. The nature of the radionuclides considered may have consequences for the choice of sanitation techniques. Because possible sources and cases of soil pollution may have important consequences for the Dutch policy on soil sanitation, a short overview is given of data published on these subjects. The foundation and the control of intervention levels requires insight in the relative importance of pollution pathways. As a result, pathways have been given ample attention. 9 figs., 17 tabs., 66 refs

    Full Text Available The Sandy Lake Health and Diabetes Project (SLHDP was initiated in 1991 as a partnership between Sandy Lake First Nation and researchers interested in addressing the high rates of type 2 diabetes mellitus (T2DM in the community. Following the expressed wishes of the community, the SLHDP has encompassed a variety of community-wide interventions and activities including: community surveys to document T2DM prevalence and risk factors, the Northern Store program aimed at increasing the availability and knowledge of healthy food options, a home visit program for the prevention and management of T2DM, a local diabetes radio show, a school diabetes curriculum for grades 3 and 4, a community-wide walking trail to encourage increased physical activity, youth diabetes summer camps, and a variety of community events focusing on nutrition and physical activity. Over the twenty-two year existence of the SLHDP, the community has taken ownership of the program and activities have evolved in alignment with community needs and priorities. This paper discusses the history, implementation, evaluation and outcomes of the SLHDP and describes its sustainability. The SLHDP is a model of culturally appropriate participatory research that is iterative, with reciprocal capacity building for both key community stakeholders and academic partners.

    Background: Abciximab is beneficial in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI). However, the optimal administration route of the initial bolus of abciximab, that is, intravenous (IV) versus intracoronary (IC), has...... been questioned. Preliminary studies suggest that IC-bolus is superior, probably due to high local concentration. In this study, we assess the short-term efficacy and safety of IC compared to IV bolus of abciximab in patients with STEMI during pPCI. Methods: In 2006-2008, we randomized 355 STEMI...... patients who underwent pPCI and had indication for abciximab to either IV or IC bolus followed by a 12-hour IV infusion.

    Full Text Available Abstract Background Frailty is a term commonly used to describe the condition of an older person who has chronic health problems, has lost functional abilities and is likely to deteriorate further. However, despite its common use, only a small number of studies have attempted to define the syndrome of frailty and measure its prevalence. The criteria Fried and colleagues used to define the frailty syndrome will be used in this study (i.e. weight loss, fatigue, decreased grip strength, slow gait speed, and low physical activity. Previous studies have shown that clinical outcomes for frail older people can be improved using multi-factorial interventions such as comprehensive geriatric assessment, and single interventions such as exercise programs or nutritional supplementation, but no interventions have been developed to specifically reverse the syndrome of frailty. We have developed a multidisciplinary intervention that specifically targets frailty as defined by Fried et al. We aim to establish the effects of this intervention on frailty, mobility, hospitalisation and institutionalisation in frail older people. Methods and Design A single centre randomised controlled trial comparing a multidisciplinary intervention with usual care. The intervention will target identified characteristics of frailty, functional limitations, nutritional status, falls risk, psychological issues and management of chronic health conditions. Two hundred and thirty people aged 70 and over who meet the Fried definition of frailty will be recruited from clients of the aged care service of a metropolitan hospital. Participants will be followed for a 12-month period. Discussion This research is an important step in the examination of specifically targeted frailty interventions. This project will assess whether an intervention specifically targeting frailty can be implemented, and whether it is effective when compared to usual care. If successful, the study will establish a

    Glomerular hypertrophy is the main pathological characteristic in the early stage of diabetic nephropathy (DN), and its regulatory mechanism is closely related to mammalian target of rapamycin (mTOR) signaling pathway activity. mTOR includes mTOR complex 1 (mTORC1) and mTOR complex 2(mTORC2), in which, the upstream pathway of mTORC1 is phosphatidylinositol-3-kinase (PI3K)/serine-threonine kinase(Akt)/adenosine monophosphate activated protein kinase(AMPK), and the representative signaling molecules in the downstream pathway of mTORC1 are 4E-binding proteins(4EBP) and phosphoprotein 70 S6Kinase(p70S6K). Some Chinese herbal extracts could improve cell proliferation via intervening the expressions of the key molecules in the upstream or downstream of PIK/Akt/mTOR signaling pathway in vivo. As for glomerular mesangial cells(MC) and podocyte, mTOR plays an important role in regulating glomerular inherent cells, including adjusting cell cycle, energy metabolism and matrix protein synthesis. Rapamycin, the inhibitor of mTOR, could suppress glomerular inherent cell hypertrophy, cell proliferation, glomerular basement membrane (GBM) thickening and mesangial matrix deposition in model rats with DN. Some Chinese herbal extracts could alleviate glomerular lesions by intervening mTOR signaling pathway activity in renal tissue of DN animal models or in renal inherent cells in vivo and in vitro.

METHODS A prospective study and interventional methods were performed on surgical site in patients undergoing six surgeries in the hospital. Both single and multiple regression logistic analysis were executed with SPSS on the 10 factors including , on-site intervention in the risk factors. RESULTS Among 519 patients undergoing surgeries, the incidence rate of SSI was 1. 9%; the insulation measure and the surgical drainage had the most significant correlation with the SSI (P<0. 01) ;after the on-site intervention, the incidence rates of the SSI caused by colorectal surgery and gallbladder bile duct surgery decreased to 7. 1% and 6. 3% , respectively, the simple cholecystectomy decreased to 1. 6%; the utilization rale of the prophylactic antibiotics of the patients undergoing thyroidectomy or high ligation of the great saphenous vein decreased from 100. 0% to below 30. 0%. CONCLUSION The intraoperative low temperature,drainage,hospital stay are the high-risk factors for SSI, and the on-site intervention in the target monitoring is an powerful way to control the high-risk factors.%目的 探讨现场干预对外科手术部位感染(SSI)目标性监测的作用,降低SSI发生率.方法 采用干预性研究方法,对6种手术患者的手术部位感染及相关因素进行了目标性监测,对危险因素进行现场干预.结果 共监测手术患者519例,SSI发生率为1.9%;手术部位感染与年龄、保温措施、ASA评分、住院天数、是否引流有关(P<0.05);其中保温措施、外科引流与手术部位感染有显著关系(P<0.01);经过现场干预,直肠、结肠手术及胆囊、胆管手术的手术部位感染率分别下降至7.1%及6.3%,单纯胆囊切除术下降至1.6%;甲状腺切除术及大隐静脉高位结扎术患者预防性抗菌药物使用率从100.0%降至<30.0%.结论 术中低体温、

    MR guided interventional procedures have become useful clinical tools recently. In this article the authors discuss the usefulness and problems of MR-guided needle biopsy and MR-guided laser induced thermotherapy (LITT) for clinical cases. MR enabled optimal plane monitoring with desired image contrast during the procedure without X-ray irradiation for puncture and tissue sampling. Also only MR could non-invasively provide interstitial temperature information during laser ablation. Bone and soft tissue lesions are likely to be candidates for MR interventions because they are free from any physiological motions, and radiologists should compare MR-guidance with CT- or US guidance for individual cases in order to achieve a less invasive diagnosis or treatment.

    2000-01-01

    Historically, interventions to prevent STD/HIV transmission have been categorized by program methodology rather than defining the content and nature of the intervention. A new taxonomy is needed to help expand the scope of interventions that can be used to prevent STD and HIV transmission. The taxonomy defines two major types of interventions, individual-level and structural level. The former targets risk factors attributable to individuals. Structural interventions target conditions outside the control of the individual. Individual-level interventions focus on counseling, screening, and treatment. They include psychological and biological interventions. Structural-level interventions address accessibility of relevant consumer products (condoms, needles), physical structures (e.g. blighted and abandoned housing, lighting, design of social facilities), social structures (policies that facilitate or constrain behaviors such as supervision of youth, and enforcement of alcohol beverage laws); and media messages (messages and images in the broadcast and print media that portray high-risk behaviors as positive and without serious consequences). A new taxonomy not only clarifies the content of preventive interventions but highlights neglected strategies involving individual biological interventions and structural interventions to prevent STD/HIV transmission.

    In the last 2 decades, school bullying has become a topic of public concern and research around the world. This has led to action to reduce the problem. We review interventions targeted at the school level (for example, whole school policy, classroom climate, peer support, school tribunal, and playground improvement), at the class level (for example, curriculum work), and at the individual level (for example, working with specific pupils). Effectiveness of interventions has been sporadically assessed. We review several systematically evaluated, large-scale, school-based intervention programs. Their effectiveness has varied, and we consider reasons for this. We suggest ways to improve the evaluation and comparability of studies, as well as the effectiveness of future interventions.

    Grocery stores represent a context in which a majority of people's food purchases occur. Considering the nutrition quality of the population's food intake has dramatically decreased, understanding how to improve food choice in the grocery store is paramount to healthier living. In this work, we detail the type of financial resources from which shoppers could draw (i.e., personal income and benefits from government food assistance programs to low income populations) and explain how these financial resources are allocated in the grocery store (i.e., planned, unplanned, error). Subsequently, we identify a conceptual framework for shopper marketing nutrition interventions that targets unplanned fruit and vegetable purchases (i.e., slack, or willingness to spend minus list items). Targeting slack for fresh fruit and vegetable purchases allows retailers to benefit economically (i.e., fruit and vegetables are higher margin) and allows shoppers to improve their nutrition without increasing their budgets (i.e., budget neutrality). We also provide preliminary evidence of what in-store marketing of fresh fruits and vegetables could entail by modifying grocery carts and grocery floors to provide information of what is common, normal, or appropriate fruit and vegetable purchases. In each example, fresh fruit and vegetable purchases increased and evidence suggested shopper budget neutrality. To provide context for these results, we detail measurement tools that can be used to measure shopper behaviors, purchases, and consumption patterns. Finally, we address theoretical, practical, and policy implications of shopper marketing nutrition interventions. PMID:24726388

    2000-12-01

    Interventional radiology is now widely performed for the treatment of liver tumors, because surgery is sometimes limited by poor liver function. Transcatheter arterial chemoembolization(TACE) is an effective therapy for hepatocellular carcinoma. Lipiodol TACE shows a strong antitumor effect because of the overflow of excess iodized oil into the portal veins, and segmental TACE is recommended to avoid deteriorating liver function. Selective CT arteriography is performed in order to decide on the treatment area, and TACE under CT guidance leads to effective results in terms of dense accumulation of the chemotherapeutic drug in the individual tumors that are affected by the ischemic state and anticancer drugs. Percutaneous microwave or radiofrequency coagulation therapy is adequate for a few of the hypovascular tumors. Excessive coagulation through the needle tract is indispensable in these therapies, and precisely designed puncture is necessary to minimize damage to the liver parenchyma. Selective chemotherapy to the tumor-bearing organ is the first step in a number of liver tumors. Continuous intra-arterial infusion chemotherapy is performed for multiple liver metastases. The reservoir implantation technique is percutaneously achieved via the left subclavian artery under ultrasound guidance, without the exposure of an artery in the incision method, which can induce thrombus formation.

  7. Aortoiliac interventions

    International Nuclear Information System (INIS)

    Full text: Atheromatosis is a systemic disease that involves various vascular beds. The most known risk factors are smoking, diabetes mellitus, dyslipedemia, hypertension, advanced age, black gender and male sex. Occlusive aortoiliac disease is due to atheromatosis in the vast majority of cases and is a common distribution of that pathology. Historically aortoiliac occlusions were treated with surgery. Nowadays, the endovascular minimally invasive techniques have revolutionized the treatment of such lesions. The success rate is extremely high with a technical success of 96%. Long term (5 years) patency of the diseased vessel can be as high as 71%. These results combined to the advent of new materials and techniques have set the new standards for treating aortoiliac occlusive disease. The first TASC recommendations (TASC I) were recently revised (TASC II) and the new guidelines (TASC III) will be shortly published. On the other hand endovascular techniques are not always successful. Technical failure (inability to cross the lesion) is estimated to be approximately 5% in single short iliac occlusions and can rise up to 15- 20% in complex long or multiple occlusive lesions. Possible, although not very frequent, complications are dissection, rupture and distal embolization. In the case of total occlusions we can use different materials and techniques. For example in an acute or subacute total occlusion chemical (urokinase or rtPA), mechanical or aspiration thrombolysis can be implemented. These minimally invasive techniques are of the outmost importance if we consider that the majority of the patients are old with a high rate of cardiac and other co-morbidities and therefore cannot go into surgery. That is the reason why the risk of morbidity and mortality following open surgical intervention remains high (5 - 20%). In chronic lesions we can use rentry catheters, glidewires, laser or thrombolysis/thrombectomy (if the clot is not very 'old'). Nevertheless, it should

    Helicobacter species colonizes the stomach and are associated with the development of gastritis disease. Drugs for treatment of Helicobacter infection relieve pain or gastritis symptoms but they are not targeted specifically to Helicobacter pylori. Therefore, there is dire need for discovery of new drug targets and drugs for the treatment of H. pylori. The main objective of this study is to screen the potential drug targets by in silico analysis for the potent strains of H. pylori which include HpB38, HpP12, HpG27, Hpshi470 and HpSJM180. Genome and metabolic pathways of pathogen H. pylori and the host Homosapien sapiens are compared and genes which were unique to H. pylori were filtered and catalogued. These unique genes were subjected to gene property analysis to identify the potentiality of the drug targets. Among the total number of genes analysed in different strains of H. pylori nearly 558, 569, 539, 569, 567 number of genes in HpB38, HpP12, HpG27, Hpshi470 and HpSJM180 found qualified as unique molecules and among them 17 qualified as potential drug targets. Membrane fusion protein of hefABC efflux system, 50 S ribosomal protein L33, Hydrogenase expression protein/formation of HypD, Cag pathogenecity island protein X, Apolipoprotein N acyl transferase, DNA methyalse, Histone like binding protein, Peptidoglycan-associated lipoprotein OprL were found to be critical drug targets to H. pylori. Three (hefABC efflux system, Hydrogenase expression protein/formation of HypD, Cag pathogenecity island protein X) of the 17 predicted drug targets are already experimentally validated either genetically or biochemically lending credence to our unique approach.

  13. CERN: Fixed target targets

    International Nuclear Information System (INIS)

    Full text: While the immediate priority of CERN's research programme is to exploit to the full the world's largest accelerator, the LEP electron-positron collider and its concomitant LEP200 energy upgrade (January, page 1), CERN is also mindful of its long tradition of diversified research. Away from LEP and preparations for the LHC proton-proton collider to be built above LEP in the same 27-kilometre tunnel, CERN is also preparing for a new generation of heavy ion experiments using a new source, providing heavier ions (April 1992, page 8), with first physics expected next year. CERN's smallest accelerator, the LEAR Low Energy Antiproton Ring continues to cover a wide range of research topics, and saw a record number of hours of operation in 1992. The new ISOLDE on-line isotope separator was inaugurated last year (July, page 5) and physics is already underway. The remaining effort concentrates around fixed target experiments at the SPS synchrotron, which formed the main thrust of CERN's research during the late 1970s. With the SPS and LEAR now approaching middle age, their research future was extensively studied last year. Broadly, a vigorous SPS programme looks assured until at least the end of 1995. Decisions for the longer term future of the West Experimental Area of the SPS will have to take into account the heavy demand for test beams from work towards experiments at big colliders, both at CERN and elsewhere. The North Experimental Area is the scene of larger experiments with longer lead times. Several more years of LEAR exploitation are already in the pipeline, but for the longer term, the ambitious Superlear project for a superconducting ring (January 1992, page 7) did not catch on. Neutrino physics has a long tradition at CERN, and this continues with the preparations for two major projects, the Chorus and Nomad experiments (November 1991, page 7), to start next year in the West Area. Delicate neutrino oscillation effects could become

  18. Target capture and target ghosts

    Science.gov (United States)

    Auerbach, Steven P.

    1996-05-01

    Optimal detection methods for small targets rely on whitened matched filters, which convolve the measured data with the signal model, and whiten the result with the noise covariance. In real-world implementations of such filters, the noise covariance must be estimated from the data, and the resulting covariance estimate may be corrupted by presence of the target. The resulting loss in SNR is called 'target capture'. Target capture is often thought to be a problem only for bright targets. This presentation shows that target capture also arises for dim targets, leading to an SNR loss which is independent of target strength and depends on the averaging method used to estimate the noise covariance. This loss is due to a 'coherent beat' between the true noise and that portion of the estimated noise covariance due to the target. This beat leads to 'ghost targets', which diminish the target SNR by producing a negative target ghost at the target's position. A quantitative estimate of this effect will be given, and shown to agree with numerical results. The effect of averaging on SNR is also discussed for data scenes with synthetic injected targets, in cases where the noise covariance is estimated using 'no target' data. For these cases, it is shown that the so-called 'optimal' filter, which uses the true noise covariance, is actually worse than a 'sub-optimal' filter which estimates the noise from scene. This apparent contradiction is resolved by showing that the optimal filter is best if the same filter is used for many scenes, but is outperformed by a filter adapted to a specific scene.

    Interventional MRI is in its early stages of development. Nevertheless, the design of new interventional MRI scanners that allow maximum direct access to the patient combined with the development of new interventional MRI pulse sequences and localization systems, means that the archetypal operating rooms of the 21st century may well contain dedicated interventional MRI units for combined radiological and surgical procedures. The present article looks at the state of interventional MRI today and looks ahead to what may be forthcoming in the not-too-distant future.

  2. The experiment of interventional pulmonary lobectomy

    International Nuclear Information System (INIS)

    Objective: To study the feasibility of interventional pulmonary lobectomy by animal experiment. Methods: Twelve healthy dogs were divided into three groups randomly, with 4 in each. Group A: the target bronchus and alveoli were filled with emulsion of lipiodol and alveolar cells damage liquors and then the target bronchus was occluded with Polymethylmethacrylate (PMMA) . Group B: The target bronchus was only occluded with PMMA. Group C: Pulmonary lobe was resected surgically. Arterial blood gases were measured at the time of pre-procedure and post-procedure and then 1st, 2nd, 3rd and 4th week after the procedure respectively. Chest radiography histology and bacterial culture of tissue of target lung lobe were made after 4 weeks. Results: There was a significant difference in arterial blood-gas among 3 groups pre-procedure in comparison with those of post-procedure immediately (P0.05) in comparing with 1st, 2nd, 3rd and 4th week after the procedure. Atelectasis was shown radiologically with histological formation of fibrosis of target lung lobe but no bacteria grew in target tissue 4th week after the procedure. There were two cases of lung atelectasis but no pulmonary fibrosis occluded in group B. Conclusions: Interventional pulmonary lobectomy might be obtained after the target bronchus and pulmonary alveoli were filled with emulsion of lipiodol and alveolar cells damage liquors and then the target bronchus was occluded with PMMA.

    Anxiety and pain are common responses to surgery, and both can negatively affect patient outcomes. Music interventions have been suggested as a nonpharmacological intervention to alleviate pain and anxiety during surgical treatment. Although the data are somewhat mixed, the research suggests that music-based interventions are effective in reducing anxiety, pain perception, and sedative intake. The majority of studies have focused on interventions during the postoperative period and address pain reduction, with preoperative use of music targeting anxiety reduction the second most commonly cited objective. Most of the studies found in the literature involve passive music listening via headphones. The data suggest that researcher-selected music is most effective in reducing anxiety, primarily because it incorporates evidence-based parameters such as consistent tempo and dynamics, stable rhythms, and smooth melodic lines. Finally, the literature suggests that music therapists can serve as experts to help medical personnel identify effective implementation strategies. PMID:22948329

  5. Preventing Diabetes: Early Versus Late Preventive Interventions.

    Science.gov (United States)

    Tuomilehto, Jaakko; Schwarz, Peter E H

    2016-08-01

    There are a number of arguments in support of early measures for the prevention of type 2 diabetes (T2D), as well as for concepts and strategies at later intervention stages. Diabetes prevention is achievable when implemented in a sustainable manner. Sustainability within a T2D prevention program is more important than the actual point in time or disease process at which prevention activities may start. The quality of intervention, as well as its intensity, should vary with the degree of the identified T2D risk. Nevertheless, preventive interventions should start as early as possible in order to allow a wide variety of relatively low- and moderate-intensity programs. The later the disease risk is identified, the more intensive the intervention should be. Public health interventions for diabetes prevention represent an optimal model for early intervention. Late interventions will be targeted at people who already have significant pathophysiological derangements that can be considered steps leading to the development of T2D. These derangements may be difficult to reverse, but the worsening of dysglycemia may be halted, and thus the clinical onset of T2D can be delayed. PMID:27440823

  6. E-Health Interventions for Suicide Prevention

    2014-08-01

    Full Text Available Many people at risk of suicide do not seek help before an attempt, and do not remain connected to health services following an attempt. E-health interventions are now being considered as a means to identify at-risk individuals, offer self-help through web interventions or to deliver proactive interventions in response to individuals’ posts on social media. In this article, we examine research studies which focus on these three aspects of suicide and the internet: the use of online screening for suicide, the effectiveness of e-health interventions aimed to manage suicidal thoughts, and newer studies which aim to proactively intervene when individuals at risk of suicide are identified by their social media postings. We conclude that online screening may have a role, although there is a need for additional robust controlled research to establish whether suicide screening can effectively reduce suicide-related outcomes, and in what settings online screening might be most effective. The effectiveness of Internet interventions may be increased if these interventions are designed to specifically target suicidal thoughts, rather than associated conditions such as depression. The evidence for the use of intervention practices using social media is possible, although validity, feasibility and implementation remains highly uncertain.

  13. A Systematic Review of Physical Activity Interventions in Hispanic Adults

    International Nuclear Information System (INIS)

    Healthy People 2020 aims to achieve health equity, eliminate disparities, and improve the health of all groups. Regular physical activity (PA) improves overall health and fitness and has the capability to reduce risk for chronic diseases. Identifying barriers which relate to the Hispanic population is important when designing PA interventions. Therefore, the purpose was to review existing PA interventions targeting Hispanic adults published between 1988 and 2011. This paper was limited to interventions which included more than 35% Hispanic adults (n=20). Most of the interventions were community based (n=16), although clinical, family-based, and faith-based settings were also represented. Interventions incorporated theory (n=16), with social cognitive theory and trans theoretical model being used most frequently. Social support was integral, building on the assumption that it is a strong motivator of PA. Each of the interventions reported success related to PA, social support, and/or BMI. Lessons learned should be incorporated into future interventions.

    Increasing condom use to prevent sexually transmitted infections is a key public health goal. Interventions are more likely to be effective if they are theory- and evidence-based. The Behaviour Change Wheel (BCW) provides a framework for intervention development. To provide an example of how the BCW was used to develop an intervention to increase condom use in heterosexual men (the MenSS website), the steps of the BCW intervention development process were followed, incorporating evidence from the research literature and views of experts and the target population. Capability (e.g. knowledge) and motivation (e.g. beliefs about pleasure) were identified as important targets of the intervention. We devised ways to address each intervention target, including selecting interactive features and behaviour change techniques. The BCW provides a useful framework for integrating sources of evidence to inform intervention content and deciding which influences on behaviour to target. PMID:27528531

  15. Two Optimal Strategies for Active Learning of Causal Models from Interventions

    CERN Document Server

    Hauser, Alain

    2012-01-01

    From observational data alone, a causal DAG is in general only identifiable up to Markov equivalence. Interventional data generally improves identifiability; however, the gain of an intervention strongly depends on the intervention target, i.e., the intervened variables. We present active learning strategies calculating optimal interventions for two different learning goals. The first one is a greedy approach using single-vertex interventions that maximizes the number of edges that can be oriented after each intervention. The second one yields in polynomial time a minimum set of targets of arbitrary size that guarantees full identifiability. This second approach proves a conjecture of Eberhardt (2008) indicating the number of unbounded intervention targets which is sufficient and in the worst case necessary for full identifiability. We compare our two active learning approaches to random interventions in a simulation study.

  18. Percutaneous intervention in obstructive

    International Nuclear Information System (INIS)

    Percutaneous intervention procedures in obstructive uropathy include percutaneous nephrostomy tube placements, nephroureteral stents, percutaneous nephrostomy combined with ureteral embolization, percutaneous management of stone disease, suprapubic tube placements into the bladder, and perinephric/retroperitoneal urinomas/abscesses drainages. Percutaneous nephrostomy is performed to relieve urinary obstruction or divert the urinary stream away from the ureter or bladder. Patients are given preprocedure antibiotics. Percutaneous nephrostomies can be emergent cases because of risk of pyuria and sepsis from a stagnant urine collection. The procedure is performed using both ultrasound and fluoroscopy (or fluoroscopy alone using anatomic landmarks, or an internal radiopaque calculus, or delayed phase excretion of the contrast into the renal collecting system) under local anesthesia or conscious sedation. Ureteral stents are placed to bypass an obstructing stone or to stent across of an area of stricture or ureteral laceration. Stents may be placed by the urologist via a transurethral approach or by the interventional radiologist via a percutaneous approach. The decision as to method of stent placement is based upon the location and accessibility of the ureteral pathology. Ureteral embolization is performed in patients with unresectable tumors of the pelvis with long-standing nephrostomy tubes and distal urine leaks refractory to other treatments. Coils, gelfoam and liquid embolic materials can be used. Ureteral embolization for ureteral fistulas and incontinence is technically successful in 100% of the patients. Complications include bleeding, infection, ureteral or renal injury, and deployment (or movement) of the coils within the renal pelvis. Percutaneous management of stone disease, including renal, ureteral, and bladder stones requires close cooperation between the urologist and interventional radiologist, because of availability of sonographic lithotripsy

  19. Antiproton Target

    CERN Multimedia

    1980-01-01

    Antiproton target used for the AA (antiproton accumulator). The first type of antiproton production target used from 1980 to 1982 comprised a rod of copper 3mm diameter and 120mm long embedded in a graphite cylinder that was itself pressed into a finned aluminium container. This assembly was air-cooled and it was used in conjunction with the Van der Meer magnetic horn. In 1983 Fermilab provided us with lithium lenses to replace the horn with a view to increasing the antiproton yield by about 30%. These lenses needed a much shorter target made of heavy metal - iridium was chosen for this purpose. The 50 mm iridium rod was housed in an extension to the original finned target container so that it could be brought very close to the entrance to the lithium lens. Picture 1 shows this target assembly and Picture 2 shows it mounted together with the lithium lens. These target containers had a short lifetime due to a combination of beam heating and radiation damage. This led to the design of the water-cooled target in...

    Interobserver variability in the definition of target volumes (TVs) is a well-known confounding factor in (multicentre) clinical studies employing radiotherapy. Therefore, detailed contouring guidelines are provided in the prospective randomised multicentre PET-Plan (NCT00697333) clinical trial protocol. This trial compares strictly FDG-PET-based TV delineation with conventional TV delineation in patients with locally advanced non-small cell lung cancer (NSCLC). Despite detailed contouring guidelines, their interpretation by different radiation oncologists can vary considerably, leading to undesirable discrepancies in TV delineation. Considering this, as part of the PET-Plan study quality assurance (QA), a contouring dummy run (DR) consisting of two phases was performed to analyse the interobserver variability before and after teaching. In the first phase of the DR (DR1), radiation oncologists from 14 study centres were asked to delineate TVs as defined by the study protocol (gross TV, GTV; and two clinical TVs, CTV-A and CTV-B) in a test patient. A teaching session was held at a study group meeting, including a discussion of the results focussing on discordances in comparison to the per-protocol solution. Subsequently, the second phase of the DR (DR2) was performed in order to evaluate the impact of teaching. Teaching after DR1 resulted in a reduction of absolute TVs in DR2, as well as in better concordance of TVs. The Overall Kappa(κ) indices increased from 0.63 to 0.71 (GTV), 0.60 to 0.65 (CTV-A) and from 0.59 to 0.63 (CTV-B), demonstrating improvements in overall interobserver agreement. Contouring DRs and study group meetings as part of QA in multicentre clinical trials help to identify misinterpretations of per-protocol TV delineation. Teaching the correct interpretation of protocol contouring guidelines leads to a reduction in interobserver variability and to more consistent contouring, which should consequently improve the validity of the overall study

    Full Text Available Introduction: Opportunities for the early detection of disease are not sufficiently being taken advantage of. Specific interventions could increase the uptake of prevention programmes. A comprehensive analysis of effectiveness and cost-effectiveness of these interventions with reference to Germany is still needed. Objectives: This report aimed to describe and assess interventions to increase uptake in primary and secondary prevention and to explore the assessment of their cost-effectiveness. Methods: 29 scientific databases were systematically searched in a wide strategy. Additional references were located from bibliographies. All published systematic reviews and primary studies were assessed for inclusion without language restrictions. Teams of two reviewers identified the literature, extracted data and assessed the quality of the publications independently. Results: Four HTA reports and 22 systematic reviews were identified for the medical evaluation covering a variety of interventions. The economic evaluation was based on two HTA-reports, one meta-analysis and 15 studies. The evidence was consistent for the effectiveness of invitations and reminders aimed at users, and for prompts aimed at health care professionals. These interventions were the most commonly analysed. (Financial Incentives for users and professionals were identified in a small number of studies. Limited evidence was available for cost-effectiveness showing incremental costs for follow-up reminders and invitations by telephone. Evidence for ethical, social and legal aspects pointed to needs in vulnerable populations. Discussion: The material was heterogeneous regarding interventions used, study populations and settings. The majority of references originated from the United States and focused on secondary prevention. Approaching all target groups by invitations and reminders was recommended to increase uptake in prevention programmes in general. Conclusions: Further research

    Attention-deficit/hyperactivity disorder (ADHD) is the most common reason for referral to child and adolescent psychiatry clinics. Although stimulant medications represent an evidence-based approach to managing ADHD, psychosocial interventions for child/adolescent ADHD target functional impairments as the intervention goal, and rely heavily on behavioral therapy techniques and operant conditioning principles. Evidence-based psychosocial interventions for managing pediatric ADHD include behavioral parent training, school-based interventions relying on behavioral modification, teaching skills, and operant conditioning principles, and intensive summer treatment programs. The use of conjoint psychosocial treatments with ADHD medications may enable lower doses of each form of treatment. PMID:25455577

    The statistics profession is at a unique point in history. The need for valid statistical tools is greater than ever; data sets are massive, often measuring hundreds of thousands of measurements for a single subject. The field is ready to move towards clear objective benchmarks under which tools can be evaluated. Targeted learning allows (1) the full generalization and utilization of cross-validation as an estimator selection tool so that the subjective choices made by humans are now made by the machine, and (2) targeting the fitting of the probability distribution of the data toward the targe

    Full Text Available Abstract Background The workplace is an ideal setting for health promotion. Helping employees to be more physically active can not only improve their physical and mental health, but can also have economic benefits such as reduced sickness absence. The current paper describes the development of a three month theory-based intervention that aims to increase levels of moderate intensity physical activity amongst employees in sedentary occupations. Methods The intervention was developed using an intervention mapping protocol. The intervention was also informed by previous literature, qualitative focus groups, an expert steering group, and feedback from key contacts within a range of organisations. Results The intervention was designed to target awareness (e.g. provision of information, motivation (e.g. goal setting, social support and environment (e.g. management support and to address behavioural (e.g. increasing moderate physical activity in work and interpersonal outcomes (e.g. encourage colleagues to be more physically active. The intervention can be implemented by local facilitators without the requirement for a large investment of resources. A facilitator manual was developed which listed step by step instructions on how to implement each component along with a suggested timetable. Conclusion Although time consuming, intervention mapping was found to be a useful tool for developing a theory based intervention. The length of this process has implications for the way in which funding bodies allow for the development of interventions as part of their funding policy. The intervention will be evaluated in a cluster randomised trial involving 1350 employees from 5 different organisations, results available September 2009.

EUS provides accessto many organs and lesions which are in proximity tothe gastrointestinal tract and thus giving an opportunityto target them for therapeutic and diagnostic purposes.This modality also provides a real time opportunityto target the required area while avoiding adjacentvascular and other structures. Therapeutic EUS hasfound role in management of pancreatic fluid collections,biliary and pancreatic duct drainage in cases of failedendoscopic retrograde cholangiopancreatography,drainage of gallbladder, celiac plexus neurolysis/blockage,drainage of mediastinal and intra-abdominal abscessesand collections and in targeted cancer chemotherapyand radiotherapy. Infact, therapeutic EUS has emergedas the therapy of choice for management of pancreaticpseudocysts and recent innovations like fully coveredremovable metallic stents have improved resultsin patients with organised necrosis. Similarly, EUSguided drainage of biliary tract and pancreatic ducthelps drainage of these systems in patients with failedcannulation, inaccessible papilla as with duodenal/gastric obstruction or surgically altered anatomy. EUSguided gall bladder drainage is a useful emergentprocedure in patients with acute cholecystitis who arenot fit for surgery. EUS guided celiac plexus neurolysisand blockage is more effective and less morbid vis-à-visthe percutaneous technique. The field of interventionalEUS is rapidly advancing and many more interventionsare being continuously added. This review focuses onthe current status of evidence vis-à-vis the establishedindications of therapeutic EUS.

    Selecting the initial language of intervention for bilingual children at risk for language impairment is challenging for clinicians, as both the home and academic languages are important for children's successful communication. In this project, six Spanish-English bilingual first graders at risk for language impairment participated in an 8-week intervention program targeting vocabulary, morphosyntax, narrative, and literacy skills in both Spanish and English. Children completed 24 small-group sessions (three times a week). One group received Spanish intervention first, then English, and another group received English first, then Spanish. The systematic use of both languages in intervention resulted in overall gains in vocabulary and narrative skills in this short-term intervention. Language condition groups differed in performance on oral narratives and semantics. Clinical recommendations for selecting the initial language of intervention are discussed. PMID:25922998

  15. Interventional procedures for liver tumors: an overview

    International Nuclear Information System (INIS)

    Full text: Liver tumor interventions has a long story starts from the early '70s. The last 15 years show a significant speeding up by increasing the treatment numbers and by uprising of several promising technical solution on the endovascular and the ablative field as well. The interventional radiologist can hardly navigate their own practice by lacking the clear evidences about these new toys. On the other hand our potential target lesions have tremendous variability, by type, by biological behavior and treatment-sensitivity. As a third aspect, the economical and financial limits are more and more important for the communities. The multidisciplinary approach, the combination of different therapeutical options, using them in a well organised, pre-shaped and personalised fashion, seems to be the goal,which can lead us and our patients to the highest effectiveness. The lecture will overview the short history, the present and the possible future of liver tumor interventions from this point of view

    PURPOSE: Shift workers are exposed to more physical and psychosocial stressors in the working environment as compared to day workers. Despite the need for targeted prevention, it is likely that workplace interventions less frequently reach shift workers. The aim was therefore to investigate whether...... the reach of workplace interventions varied between shift workers and day workers and whether such differences could be explained by the quality of leadership exhibited at different times of the day. METHODS: We used questionnaire data from 5361 female care workers in the Danish eldercare sector. The...... workers were less likely to be reached by workplace interventions. For example, night workers less frequently reported that they had got more flexibility (OR 0.5; 95 % CI 0.3-0.7) or that they had participated in improvements of the working procedures (OR 0.6; 95 % CI 0.5-0.8).

    Tarrier, N; Barrowclough, C

    1990-10-01

    Studies that have attempted to reduce schizophrenic relapse by the use of family interventions are described. Results from studies that implemented behavioral family interventions with patients who were identified as high risk because of the expressed emotion status of their relatives have demonstrated that relapse rates can be significantly reduced over a 2-year postdischarge follow-up period. A number of ongoing studies, especially those that are investigating the interaction of family interventions and different medication regimes, are also discussed. Areas for further investigation are identified, for example: the use of multiple outcome measures, the use of single-case studies and the development of ideographic assessment measures, the interaction of biological and environmental influences, the alleviation of the burden of care, the involvement of the consumer in services, the development of behavioral formulations and analysis of family engagement and compliance, staff training in intervention methods, and the translation of research results into clinical practice.

    2006-12-01

    Full Text Available Sam J Lehman, Derek P ChewDepartment of Medicine, Flinders University, South Australia, AustraliaAbstract: Bivalirudin is a member of the direct thrombin inhibitor group of anticoagulants. It has been evaluated as an alternative to unfractionated and low-molecular-weight heparins in the settings of percutaneous coronary intervention (PCI and acute coronary syndrome (ACS. Results of clinical trials to date suggest bivalirudin is a viable alternative to the use of a heparin combined with a glycoprotein (GP IIb/IIIa inhibitor in these settings. Thrombin has a central role in coagulation and platelet activation in ACS and during PCI. Its direct inhibition is an attractive target for therapy in these settings. Bivalirudin is a 20 amino acid polypeptide hirudin analog. It displays bivalent and reversible binding to the thrombin molecule, inhibiting its action. Direct inhibition of thrombin with bivalirudin has theoretical pharmacokinetic and pharmacodynamic advantages over the indirect anticoagulants. A reduction in rates of bleeding without loss of anti-thrombotic efficacy has been a consistent finding across multiple clinical trials. There may be economic benefits to the use of bivalirudin if it permits a lower rate of use of the GP IIb/IIIa inhibitors. This article reviews the pharmacology of bivalirudin and clinical trial evidence to date. There are now data from multiple clinical trials and meta-analyses in the setting of ACS and PCI. Early results from the acute catheterization and urgent intervention strategy (ACUITY trial are discussed.

  6. Cultural Intervention in English and Chinese Translation

    Institute of Scientific and Technical Information of China (English)

    ZHONG Wei-he

    2002-01-01

    In this paper, the author defines translation as an act of communication in a cross-cultural context, the main aim of which is to establish communication between members of different cultures in accordance with previously determined communicative target purpose. He then discusses the unavoidable cultural intervention in the process of translation. Cases in aesthetic preference, political involvement and ethical tradition are studied to prove his proposition that translation is not only linguistic transfer, but also cultural transfer, and that "the more inclusive the target culture is, the closer the translation is to the source culture, the more exclusive the target culture is, the closer the translation must be to the target culture." In the last part of the paper, he proposes strategies of translation (especially for the translation between English and Chinese) with which we can tackle the cultural barriers in the process of translation, i.e. distortion,ignoring and coinage.

    Full Text Available Objective: To verify the effectiveness of nutrition intervention in changing dietary intake among school children aged 6 to 10 years old in private school, in the city of Itajaí - SC, Brazil. Methods: A non-randomized and uncontrolled intervention study, carried through four educational activities in the period from August to November, 2008 and food intake reassessed at the end. We evaluated the nutritional status by means of body mass index for age and sex, and waist circumference. The frequency of consumption before and after intervention was compared using the paired Student t test. Results: Joined in the survey 93 students (69.92% of whom 48 children (54.5% were normal weight, while 36 (40.9% were overweight or presented obesity. The most consumed food groups, before and after intervention were: crackers and pasta; rice and fruit juice. The average frequency of sweets intake decreased after the intervention (0.54 to 0.24 times per day, p <0.001, however increased the intake of fried potatoes (0.25 to 0.65, p <0.001, pizza and hamburger (0.30 to 0.46, p = 0.028. Among girls, the intake of sweets decreased after the educational activities (0.58 to 0.12, p <0.001. Conclusions: Nutritional interventions, despite the short period of time, were effective in changing the consumption of certain foods / food groups. The results reinforce the need to carry out interventions more often and for longer periods, to promote effective changes in food consumption.

    2014-12-01

    Over the last several years, there has been a substantial increase in the number of publications reporting on Internet interventions for mental health and addictions. This paper provides a summary of the recent research on Internet interventions for the most common mental health and addictions concerns-depression, anxiety, alcohol and smoking. There is considerable evidence for the effectiveness of Internet-based interventions targeting depression, anxiety disorders, alcohol use and smoking. Small to moderate effect sizes have been reported for interventions targeting depression, anxiety and alcohol use, and smoking interventions have shown large effects. The addition of human support to depression and anxiety interventions has generally resulted in larger treatments effects, but this trend has not been observed in trials of interventions targeting alcohol use. There is some evidence that online interventions can be as effective as face-to-face therapies, at least for anxiety disorders. Despite a proliferation of research activity in this area, gaps in knowledge remain. Future research should focus on the development and evaluation of interventions for different platforms (e.g. smartphone applications), examining the long-term impacts of these interventions, determining active intervention components and identifying methods for enhancing tailoring and engagement. Careful consideration should be given to the ongoing technical and clinical expertise required to ensure that Internet interventions are delivered safely and professionally in a rapidly changing technology environment.

    <正>With increasing attention given to the development and implementation of psychological interventions during the sport injury rehabilitation process,there is a need to document the effectiveness of these interventions.The purpose of this review was to summarize the empirical findings of the effects of psychological interventions in reducing post-injury psychological consequences and improving psychological coping during the injury rehabilitation process among competitive and recreational athletes.In February 2012,utilizing a comprehensive search strategy,we conducted electronic searches of multiple electronic databases for randomized and nonrandomized control trials that evaluated interventions targeting populations of injured competitive and recreational athletes age 17 years and older.We included interventions that directly intervene on injured athletes’ psychological outcomes(e.g.,psychological consequences,psychological coping and re-injury anxiety) and utilized psychological strategies including imagery,goal-setting,relaxation,and other common techniques during the post-injury rehabilitation period.Six studies,described in seven peer-reviewed published articles,met study inclusion criteria and were included in this review.Of those studies,two included randomized control trials,two used before and after study designs and two were case study designs.Two interventions utilized guided imagery and relaxation,two interventions utilized goal-setting and one each utilized microcounseling,written disclosure,and acceptance and commitment therapy.Guided imagery/relaxation was shown to be associated with improved psychological coping and reduced re-injury anxiety. Goal setting,however,was not directly associated with the reduction of negative psychological consequences.Other psychological techniques such as microcounseling skills,acceptance and commitment therapy,and written disclosure have demonstrated effectiveness in reducing negative psychological consequences

  18. Interventional MR imaging

    International Nuclear Information System (INIS)

    Most of the applications of MRI-guided interventional examinations require real-time or quasi real-time imaging. With sequences such as TFE (Turbo-Field-Echo), TSE (Turbo-Spin-Echo), EPI (Echo-Planar-Imaging), and GRASE (Gradient-and Spin-Echo), as well as with intelligent approaches such as LoLo (Local Look), data acquisition is alrady close to meeting these requirements. The specific advantages and drawbacks of these sequences are characterised in brief. Potential applications of MRI-guided techniques in interventional radiology, of which some have been tested to date in a small numer of patients, are: percutaneous biopsy, stereotactic emplacement of electrodes for deep encephalography, percutaneous interstitial therapy, percutaneous drainage, percutaneous application of focused ultrasound, and vascular interventions.

  19. Paediatric interventional radiology

    International Nuclear Information System (INIS)

    Paediatric interventional radiology (PIR) is a rapidly-growing subspecialty, which offers a wide range of procedures applicable to almost all areas of hospital paediatrics. There are many important differences between paediatric and adult practice in interventional radiology, including disease processes and treatment goals, anatomical considerations, periprocedural patient management, radiation exposure optimisation and legal aspects. The use of retrievable or absorbable interventional devices such as stents will probably become more widespread in PIR practice. Recent advances in the technology of imaging equipment have been accompanied by an increase in the complexity of the work done by the radiographer. These developments present challenges and opportunities related to training and maintenance of skills, staffing arrangements, and the potential for advanced practice. It is likely that specialisation in PIR will become a more common role for radiographers in the future

    2015-06-01

    Similar to other Middle Eastern countries, breast cancer is the most common cancer among women in Qatar with increasing incidence and mortality rates. High mortality rates of breast cancer in the Middle Eastern countries are primarily due to delayed diagnosis of the disease. Thus screening and early detection of breast cancer are important in reducing cancer morbidity and mortality. With the aim of updating knowledge on existing interventions and developing effective intervention programs to promote breast cancer screening in Arabic populations in Qatar, this review addresses the question: What interventions are effective in increasing breast cancer knowledge and breast cancer screening rates in Arabic populations in Arabic countries and North America? Systematic literature review was performed to answer the proposed question. As the result of the search, six research studies were identified and appraised. From the findings, we infer several insights: (a) a language-appropriate and culturally sensitive educational program is the most important component of a successful intervention regardless of the study setting, (b) multi-level interventions that target both women, men, health care professionals, and/or larger health care system are more likely to be successful than single educational interventions or public awareness campaigns, and (c) more vigorous, personal and cognitive interventions that address psychosocial factors are likely to be more effective than less personal and informative interventions. This review has important implications for health care providers, intervention planners, and researchers. PMID:23975014

    Full Text Available Abstract Background The prevalence of childhood obesity has increased during the past decades and is now considered an urgent public health problem. Although stabilizing trends in obesity prevalence have been identified in parts of Europe, preventive efforts in children are still needed. Using the socio-ecological approach as the underlying theoretical perspective, the IDEFICS project aimed to develop, implement and evaluate a community-based intervention for the prevention of childhood obesity in eight European countries. The aim of the present manuscript was to describe the content and developmental process of the IDEFICS intervention. Methods The intervention mapping protocol (IMP was used to develop the community-based intervention for the prevention of childhood obesity in 3 to 10 years old children. It is a theory- and evidence-based tool for the structured planning and development of health promotion programs that requires the completion of six different steps. These steps were elaborated by two coordinating centers and discussed with the other participating centers until agreement was reached. Focus group research was performed in all participating centers to provide an informed basis for intervention development. Results The application of the IMP resulted in an overall intervention framework with ten intervention modules targeting environmental and personal factors through the family, the school and the community. The summary results of the focus group research were used to inform the development of the overall intervention. The cultural adaptation of the overall intervention was realised by using country specific focus group results. The need for cultural adaptation was considered during the entire process to improve program adoption and implementation. A plan was developed to evaluate program effectiveness and quality of implementation. Conclusions The IDEFICS project developed a community-based intervention for the prevention of

    Full Text Available Abstract Treatment of patients with chronic diseases will be one of the main challenges of medicine in the future. This paper presents an overview of different origins, mechanism, and symptoms necessary for understanding new and different interventions that include a psychosomatic view. In a psychosomatic therapeutic intervention there are very different targets, such as psychological symptoms, personality traits, attitudes toward disease and life, risk behaviour, and social isolation and as biological targets the change of autonomic imbalance and of the effects of the psycho-endocrinological or psycho-immunological stress responses. And there are also different psychosomatic measures that influence the individual biological, psychological and sociological targets. There is a need to give different answer to different questions in the field of psychosomatic and behavioral medicine. Comparative effectiveness research is an important strategy for solving some methodological issues. What is the target of treatment for different diseases: Symptom reduction, healing, or limiting progression to the worst case - the death of patients. We know that, the patient-physician relationship is important for every medical/therapeutic action for patients with chronic diseases. This volume of BioPsychoSocial Medicine will present four different psychosomatic treatment studies from the clinical field in the sense of phase 2 studies: Reports of patients with obesity, anorexia nervosa, chronic somatoform pain and coronary artery disease were presented

    Background Many families rely on child care outside the home, making these settings important influences on child development. Nearly 1.5 million children in the U.S. spend time in family child care homes (FCCHs), where providers care for children in their own residences. There is some evidence that children in FCCHs are heavier than those cared for in centers. However, few interventions have targeted FCCHs for obesity prevention. This paper will describe the application of the Intervention M...

    Full Text Available Introduction: Globally, HIV-related stigma is prevalent in healthcare settings and is a major barrier to HIV prevention and treatment adherence. Some intervention studies have showed encouraging outcomes, but a gap continues to exist between what is known and what is actually delivered in medical settings to reduce HIV-related stigma. Methods: This article describes the process of implementing a stigma reduction intervention trial that involved 1760 service providers in 40 hospitals in China. Guided by Diffusion of Innovation theory, the intervention identified and trained about 15–20% providers as popular opinion leaders (POLs to disseminate stigma reduction messages in each intervention hospital. The intervention also engaged governmental support in the provision of universal precaution supplies to all participating hospitals in the trial. The frequency of message diffusion and reception, perceived improvement in universal precaution practices and reduction in the level of stigma in hospitals were measured at 6- and 12-month follow-up assessments. Results: Within the intervention hospitals, POL providers reported more frequent discussions with their co-workers regarding universal precaution principles, equal treatment of patients, provider-patient relationships and reducing HIV-related stigma. Service providers in the intervention hospitals reported more desirable intervention outcomes than providers in the control hospitals. Our evaluation revealed that the POL model is compatible with the target population, and that the unique intervention entry point of enhancing universal precaution and occupational safety was the key to improved acceptance by service providers. The involvement of health authorities in supporting occupational safety was an important element for sustainability. Conclusions: This report focuses on explaining the elements of our intervention rather than its outcomes. Lessons learned from the intervention implementation will

  16. Sedoanalgesia in interventional radiology

    International Nuclear Information System (INIS)

    Purpose: Development of a save and effective protocol for analgosedation of patients undergoing painful interventional procedures. Material and Methods: In a prospective trial a consecutive series of 72 adult patients underwent analgosedation during painful interventions. A radiologist performed the analgosedation, the patients received a combination of a shortly effective piperidine derivative (Alfentanil [Rapifen trademark ]; 7.5-15 μg/kg body weight) and Benzodiazepine (midazolam [Dormicum trademark ]; 20 μg/kg body weight). After pre-procedure oxygenation patients were continuously monitored. Pain and discomfort were scored using an established visual-analog pain score (0-10). A control group (n=24) had received midazolam, pentazocine or fentanyl according to the study protocol. Results: All procedures could be carried out by an interventional radiologist and a nurse and/or technologist only. In 69/72 cases adequate analgosedation could be achieved. Injection of alfentanil was titrated, with a rapid onset and short acting effect of the analgesia. Patients reported an average pain score of 2.6 vs. 4.5 in the control group. Over 55% experienced no or mild pain (score 0-3), in the control group only 8% reached this level. Conclusion: A combination of shortly effective alfentanil and midazolam allows interventional radiologists to perform major procedures alone under effective analgosedation. This medication scheme is superior to the medication upon demand. (orig.)

  2. Accuracy and speed of robotic assisted needle interventions using a modern cone beam computed tomography intervention suite: a phantom study

    International Nuclear Information System (INIS)

    To analyse the feasibility and accuracy of robotic aided interventions on a phantom when using a modern C-arm-mounted cone beam computed tomography (CBCT) device in combination with needle guidance software. A small robotic device capable of holding and guiding needles was attached to the intervention table. After acquiring a 3D data set the access path was planned on the CBCT workstation and shown on the intervention monitor. Then the robot was aligned to the live fluoroscopic image. A total of 40 punctures were randomly conducted on a phantom armed with several targets (diameter 2 mm) in single and double oblique trajectory (n = 20 each). Target distance, needle deviation and time for the procedures were analysed. All phantom interventions (n = 40) could be performed successfully. Mean target access path within the phantom was 8.5 cm (min 4.2 cm, max 13.5 cm). Average needle tip deviation was 1.1 mm (min 0 mm, max 4.5 mm), time duration was 3:59 min (min 2:07 min, max 10:37 min). When using the proposed robot device in a CBCT intervention suite, highly accurate needle-based interventional punctures are possible in a reasonable timely manner in single as well as in double oblique trajectories.

    2009-04-01

    Full Text Available Abstract Background In order to increase the chances of success in new interventions in healthcare, it is generally recommended to tailor the intervention to the target setting and the target professionals. Nonetheless, pre-intervention studies are rarely conducted or are very limited in scope. Moreover, little is known about how to integrate the results of a pre-intervention study into an intervention. As part of a project to develop an intervention aimed at improving care for the elderly in France, a pre-intervention study was conducted to systematically gather data on the current practices, issues, and expectations of healthcare professionals and managers in order to determine the defining features of a successful intervention. Methods A qualitative study was carried out from 2004 to 2006 using a grounded theory approach and involving a purposeful sample of 56 healthcare professionals and managers in Paris, France. Four sources of evidence were used: interviews, focus groups, observation, and documentation. Results The stepwise approach comprised three phases, and each provided specific results. In the first step of the pre-intervention study, we gathered data on practices, perceived issues, and expectations of healthcare professionals and managers. The second step involved holding focus groups in order to define the characteristics of a tailor-made intervention. The third step allowed validation of the findings. Using this approach, we were able to design and develop an intervention in elderly care that met the professionals' and managers' expectations. Conclusion This article reports on an in-depth pre-intervention study that led to the design and development of an intervention in partnership with local healthcare professionals and managers. The stepwise approach represents an innovative strategy for developing tailored interventions, particularly in complex domains such as chronic care. It highlights the usefulness of seeking out the

    Hobbis and Sutton (this issue) suggest that Cognitive Behavior Therapy (CBT) techniques can be used in interventions based on the Theory of Planned Behavior (TPB). Although this suggestion has merit, CBT is only one of many applicable methods for producing belief and behavior change. Moreover, CBT's primary purpose is to help people carry out intended behaviors, not to influence intentions, and that it is more useful in face-to-face than in community-level interventions. Contrary to Hobbis and Sutton's critique, TPB can accommodate core beliefs or fundamental assumptions, but the theory suggests that interventions targeted at such beliefs are less effective than interventions targeted at behavior specific beliefs.

    The rapid proliferation of community-based health education programs has out-paced the knowledge base of behavior change strategies that are appropriate and effective for public health interventions. However, experiences from a variety of large-scale studies suggest that principles and techniques of social marketing may help bridge this gap. This article discusses eight essential aspects of the social marketing process: the use of a consumer orientation to develop and market intervention techniques, exchange theory as a model from which to conceptualize service delivery and program participation, audience analysis and segmentation strategies, the use of formative research in program design and pretesting of intervention materials, channel analysis for devising distribution systems and promotional campaigns, employment of the "marketing mix" concept in intervention planning and implementation, development of a process tracking system, and a management process of problem analysis, planning, implementation, feedback and control functions. Attention to such variables could result in more cost-effective programs that reach larger numbers of the target audience. PMID:3056876

    Radiological interventions possess wide utilization in the diagnosis and treatment for pediatric patients. Pediatric interventional radiology is an important branch of interventional radiology and also an important branch of pediatric radiology. Pediatric interventional radiology has grown substantially over the last 30 years, radiologists closely cooperation with surgeons and other physicians providing a new horizon in the management of pediatric diseases in western countries. It includes pediatric cardiac interventional radiology, pediatric neuro-interventional radiology, pediatric vascular interventional radiology, pediatric nonvascular interventional radiology, pediatric tumor interventional radiology and others. In the United States, every children hospital which owns two hundred beds has to have special trained interventional radiologists in radiologic department installing with advanced digital subtraction angiographic equipment. Interventional therapeutic procedures and diagnostic angiography have been proceeding more and more for the congenital and acquired diseases of children. The promising results give use uprising and interventional therapy as an alternative or a replacement or supplement to surgical operation. Pediatric interventional radiology is rather underdeveloped in China with a few special pediatric interventional radiologist, lack of digital subtraction angiography equipment. Pediatric radiologists have no enough field for interventional procedures such as pediatric neuro-interventional radiology and pediatric vascular interventional radiology. In the contrary adult interventional radiologists do have better interventional jobs in China and Pediatric cardiologists also share the same trend. They perform angiocardiography for congenital heart diseases and treat congenital heart disease with interventional procedures including balloon dilation of valves and vessels, coil embolization of collaterals, patent ducts and other arterial fistulae

    Objective To understand the internet use and on-line behavior characters of men who have sex with men (MSM) , and explore the intention of internet-based intervention targeted to HIV high risk behaviors among them. Methods A cross-sectional study was carried out in MSM who were recruited in a gay website between December 2009 and January 2010. Data on demographic characteristics, surfing habits, HIV/AIDS related behavior, needs of information on HIV prevention and the way which they obtain the information were collected by online questionnaire survey. Chi-square test was used to determine the differences of the intention of internet-based intervention targeted to HIV high risk behaviors among MSM with different demographic characteristics and surfing habits. Results A total of 719 MSM finished the survey. Most of them were aged between 25 and 29 years (40. 61% ) , possessed high education level (78.30% ) , unmarried (87.34% ) , and identified themselves as homosexual (77.05% ). The percentage of using condom persistently when having the anal-intercourse with partners was 70.93% (510/719) during the last sex episode and 44.78% (322/719) in the last month. 29.62% of them (213/719) used to have sexual relationship with female, 57. 75% (123/213) of which used condom at last sex episode. 75. 24% of them (541/719) surfed the internet at home and 79.28% (570/719) surfed the internet everyday. 84.70% of the participants were willing to obtain information on HIV prevention through internet, while less than 30% were willing to obtain such information by face-to-face such as from CDC (28.37% , 204/719) or hospital (22.81% , 164/719).

    2015-10-01

    Full Text Available Recently, a number of procedures for interventional radiology diagnosis and treatment have been developed by the radiologists. The ‘Interventional Radiology’ refers to the therapeutic procedures performed under imaging guidance. The emergence of this specialty has been made possible by a lot of advances in the technology, imaging systems, and radiologists experience. Interventional radiologists are physicians who are experienced in minimally invasive procedures and targeted treatments which have less risk, less pain and less recovery time in comparison with the surgery. Minimizing the patient discomfort, avoid of general anesthesia, lower incidence of morbidity and mortality, and decreases the length and cost of hospitalization are some advantages of interventional radiology procedures. Similar to all medical fields, interventional procedures have been introduced and developed for the diagnosis and treatment of endocrinology procedures. In this article we aim to review and report our experience about the role of interventional radiology in venous sampling for endocrine diseases (such as parathyroid venous sampling, inferior petrosal sinus sampling, adrenal venous sampling, and venous sampling for islet cell tumors. In addition, interventional treatments of neuroendocrine cancer metastases to the liver, percutaneous ethanol injection therapy for secondary hyperparathyroidism, treatment of hyperfunctioning thyroid nodules by percutaneous ethanol injection, radiofrequency ablation of the adrenal gland neoplasms, and also establishing a cGMP pancreatic islet processing facility have been discussed in this article. Keywords: Interventional radiology, Endocrine diseases, Endovascular, Treatment

  16. DISABILITY AND EARLY INTERVENTION

    2015-04-01

    Full Text Available Disability is a present reality of our time, much discussed, opposite which attempts to implement school and social policy based on equal opportunities. Reactions to disability were over time many: from rejection and extermination to tolerance and acceptance. Being a person with disabilities involves many processes of adaptation and assimilation of those considered typical in the world and a key role in the success of these processes turns to therapeutic intervention. To cope successfully with the demands and the expectations of society, to achieve a good relationship individual-society, the child should benefit as early as possible from the therapeutic-rehabilitation process appropriate to its specific disability, to take part in group activities. Therapeutic-rehabilitation process represents the foundation pillar of harmonious development, adequate to social and school norms. Early intervention is very important and represents a big win in rehabilitation and integration of disabled children.

  17. Psychological interventions in dermatology

    Piyanjali de Zoysa

    2013-01-01

    Full Text Available The objective of this paper is to introduce and emphasize the importance of psychological interventions for those with dermatological conditions. In keeping with the current literature, the author envisages a two-tier approach in the provision of such psychological interventions. Firstly, most patients with dermatology conditions may not require psychological change. Instead, they could be approached with effective doctor-patient communication skills, within a context of empathy and positive regard. At the second tier, however, based on the clinical interview, some patients may require varying degrees of psychological change in order to better manage their illness. In such a context, a dermatologist with training in psychotherapy would be required. In the absence of such a person, the patient may be referred to a psychologist or another mental health professional trained in psychotherapy.

    International Nuclear Information System (INIS)

    Objective: To evaluate clinical application of arterial embolotherapy on hyperthyroidism. Methods: 11 patients with hyperthyroidism were performed with thyroid superior and inferior arterial super-selective arteriography and interventional embolization by polyvinyl alcohol (PVA), gelfoam particles and wool coil. Results: The procedures were succeeded in 11 patients. After the embolotherapy, the thyroid function gradually returned to normal level in 10 patients. The symptom was not controlled satisfactorily in 1 patient, who underwent the right thyroid inferior arteries super selective arteriography and interventional embolization, and then the thyroid function gradually returned to normal level. No serious complications occurred in all patients. Conclusions: Arterial embolotherapy is a safe, simple, symptomless, reliable and very effective for treatment of hyperthyroidism

  19. Cardiovascular and interventional radiology

    International Nuclear Information System (INIS)

    This year's cardiovascular section demonstrates a continued growth in the number of digests on cardivascular and general interventional topics and continued progress in MRI studies. The reader will also notice fewer digests on DSA and percutaneous stone removal compared with the 1985 and 1986 Year Books. While newer technology, such as extracorporeal shock wave lithotripsy, has significantly reduced the number of percutaneous procedures for renal calculi, other interventional procedures, such as those involving fibrinolysis, are increasing by leaps and bounds. A number of digests on benign and malignant bile duct strictures continue to shed light on the management of these difficult cases. While abscess drainage is growing and well accepted by most surgeons, articles on esophageal dilatations seem to be declining in the radiology literature, probably on the basis of fewer operations being performed by us and more being performed by endoscopists. Digests on MRI in the cardiovascular system continue to report excellent images of the aorta and of congenital heart disease

  1. Interventional radiology in urology

    International Nuclear Information System (INIS)

    Full text: Ever since starting X-rays use in medical practice, the first interventional methods used in urological practice have been applied. In modern times, based on the use of different sources for image acquisition, the interventional procedures are generally conducted under three types of image control: X-ray, including the CT, non-X-ray, including ultrasound and MRI, and mixed. On the other hand, based on the access used for carrying out the interventional procedure on the urinary tract, the procedures are divided into the following types: the percutaneous, intravascular and intraluminal. Percutaneous manipulations, the most widely used ones, include puncture and drainage of renal cysts and collections in the kidney area, drainage studies of the upper urinary tract, bladder percutaneous drainage and percutaneous nephrostomy are now routinely used. In modern times, more practical interest is percutaneous renal lithotripsy, especially in combination with extracorporeal lithotripsy and percutaneous ablation of renal tumors. Intravascular manipulation, especially after the massive use of CT angiography, are limited to therapeutic use, as in this respect the mainly use is in transluminal angioplasty and renal artery stenting, and embolization. The modern devices entering into the urological practice, allow a high degree of overlap and less invasive therapeutic methods, such as uretero renoscopy, that gradually become major therapeutic approaches to many of the most common urological diseases. It should be noted the role of retrograde ureteric pyelography and ureteral endoprosthesis in the development of these methods. Key elements to achieve maximum efficiency, as diagnostic as therapeutic, from the application of interventional procedures, especially widely used in urological practice than technical mastery of the methodology, is the use of the most appropriate methods or a combination of an exact display and good collaboration with the urologist as in

    By common consent there is a 'gold standard' in reference to which the efficacy of medical interventions needs to be evaluated. It is suggested in this paper that in educational research achievement of this gold standard is rarely possible. It does not follow, however, that research that falls short of this standard is therefore valueless; there may be many different kinds of good (and less good) reasons for accepting particular conclusions.

    Assisted reproductive technology has helped many childless couples. It has also raised questions about how appropriate the technology might be in different situations. How we understand parenthood is crucial in taking a stand on such scientific intervention. It is suggested that physicians should decide on offering artificial insemination, surrogacy and in-vitro fertilisation only after considering if the child will have good parents and if there will be legal complications from the use of the technology.

  8. Translating the Social-Ecological Perspective Into Multilevel Interventions for Family Planning: How Far Are We?

    Schölmerich, Vera L N; Kawachi, Ichiro

    Scholars and practitioners frequently make recommendations to develop family planning interventions that are "multilevel." Such interventions take explicit account of the role of environments by incorporating multilevel or social-ecological frameworks into their design and implementation. However, research on how interventions have translated these concepts into practice in the field of family planning-and generally in public health-remains scarce. This article seeks to review the current definitions of multilevel interventions and their operationalization in the field of family planning. First, we highlight the divergent definitions of multilevel interventions and show the persistent ambiguity around this term. We argue that interventions involving activities at several levels but lacking targets (i.e., objectives) to create change on more than one level have not incorporated a social-ecological framework and should therefore not be considered as "multilevel." In a second step, we assess the extent to which family planning interventions have successfully incorporated a social-ecological framework. To this end, the 63 studies featured in Mwaikambo et al.'s systematic review on family planning interventions were reexamined. This assessment indicates that the multilevel or social-ecological perspective has seldom been translated into interventions. Specifically, the majority of interventions involved some form of activity at the community and/or organizational level, yet targeted and measured intrapersonal change as opposed to explicitly targeting/measuring environmental modification.

    In the context of pre-interventional drug therapy, a premedication is given to patients who are known to have an allergy to contrast media, have renal impairment or hyperthyroidism. An already existing anticoagulation therapy, in anticipation of the planned intervention, must be reviewed and changed or even suspended as required. For peri-interventional drug therapy it is important to consider how strenuous the procedure will be as well as the general condition of the patient. Further discussion with anesthetists may be required for the planning of pain therapy or sedation during the procedure. These factors help to ensure maximum patient comfort as well as the success of the intervention. Post-interventional anticoagulation therapy, usually started peri-interventionally, plays an important role in minimizing the risk of acute thrombosis as well as in maintaining long-term functioning of the implanted material. The form of the anticoagulation therapy is set according to the type of intervention. PMID:26063076

    2016-01-01

    There is a growing emphasis on behavior change in intervention development programmes aimed at improving public health and healthcare professionals' practice. A number of frameworks and methodological tools have been established to assist researchers in developing interventions seeking to change healthcare professionals' behaviors. The key features of behavior change intervention design involve specifying the target group (i.e. healthcare professional or patient cohort), the target behavior and identifying mediators (i.e. barriers and facilitators) of behavior change. Once the target behavior is clearly specified and understood, specific behavior change techniques can then be used as the basis of the intervention to target identified mediators of behavior change. This commentary outlines the challenges for pharmacy practice-based researchers in targeting dispensing as a behavior when developing behavior change interventions aimed at pharmacists and proposes a definition of dispensing to consider in future research.

    Infections caused by meticillin-resistant Staphylococcus aureus (MRSA) remain a major problem worldwide. In England, the Department of Health set a target for decreasing MRSA bloodstream infections throughout the country by 50% by 2008, based on the 2003/2004 national figure. To aid hospitals in achieving their individual targets, guidance was provided in the form of care bundles, which were initially related to infection-control practices. Several studies have shown that decreasing the use of fluoroquinolones and/or cephalosporins results in a decrease in MRSA infection rates. In 2007 the Department of Health published guidance on antibiotic prescribing, following which the MRSA bloodstream infection rate dropped more rapidly than in 2006, and the target was met.

    Tenant evictions are a significant cause of homelessness. As evictions are a traumatic experience for those being evicted and involve high costs, preventing evictions is vital and should be part of local and national policy. In order to develop and implement preventive practices and policies, it is essential to know which interventions are effective in preventing evictions. However, little is known about these interventions. Therefore, a systematic search of the international literature, providing an overview of interventions to prevent evictions published in scientific journals and reporting on their (cost-)effectiveness, was conducted. Nine electronic databases and Google Scholar were searched for peer-reviewed and non-reviewed publications describing research into interventions to prevent tenant evictions published in English between January 1985 and May 2012. Two researchers reviewed titles, abstracts and full-text articles and eventually seven publications describing eight interventions to prevent tenant evictions were analysed. The eight interventions vary widely in terms of their target population, focus, type of support and duration, which makes comparison of results difficult. Only three effect studies on preventive interventions regarding tenant evictions were found; two researchers assessed their quality. One of these studies was of insufficient quality to assess the effectiveness of the intervention described. Legal assistance and debt advice are promising interventions that seem to be effective in decreasing the risk of eviction. The effectiveness of the other five interventions cannot be determined. More methodologically sound research into the prevention of tenant evictions is needed and future research will have to clarify what works for whom, in which context. PMID:26109137

    Objective To observe the effect of interventional targeting administration of Ad-p53 combined with ultrasound irradiation in rabbit models of hepatic VX2 tumors, as well as its impact on VEGF and MMP2. Methods Forty-two Chinchilla rabbits were collected and VX2 cancer cells were injected into the left lobe of liver on the observation in rabbits. The growth of cancer was monitored by ultrasound. Thirty rabbit models were successfully made and divided into 3 groups (each n=10) randomly. Fourteen days after transplantation of cancer cells, Ad-p53 was administrated through hepatic artery (in Ad-p53 group) or combined with ultrasound wave irradiation (in Ad-p53 + US group), while the same amount of saline was given for rabbits in control group. Three days later, the tumor size was observed with ultrasound, and then all rabbits were sacrificed, the serum VEGF level was measured by ELISA, the hepatic tissue expression of p53, MMP2 and VEGF were detected respectively by immunohistochemistry, and expression level of wild type p53 was measured using Western blot. Results No difference of tumor size was found between 3 groups before therapy. All tumor sizes increased, but the tumors in Ad-p53 + US group were relatively smaller. The efficiency of Ad-p53 transfection was improved in Ad-p53 group compared with control group, which was the highest in Ad-p53 + US group. Furthermore, the serum VEGF level decreased in Ad-p53 + US group, so did the expression of MMP2 and VEGF in Ad-p53 group and Ad-p53 + US group, more obviously in Ad-p53 + US group. Conclusion Ad-p53 can suppress the growth of hepatic VX2 tumors in rabbit models. The therapeutic efficacy of Ad-p53 can be improved by interventional targeting administration combining with ultrasound irradiation.%目的 探讨介入导向下联合超声辐照对兔VX2肝癌模型Ad-p53转染效率及该基因对VEGF、MMP2的影响.方法 青紫蓝兔42只,直视下手术,将VX2肿瘤细胞种植于肝左叶,以超声检测

    This paper examines the results of population-level interventions conducted in three settings: entire communities, worksites, and schools. Four major conclusions are discussed: (a) Directions for the next generation of community-based interventions include targeting multiple levels of influence; addressing social inequalities in disease risk; involving communities in program planning and implementation; incorporating approaches for "tailoring" interventions; and utilizing rigorous process evaluation. (b) In addition to randomized controlled trials, it is time to use the full range of research phases available, from hypothesis generation and methods development to dissemination research. (c) The public health research agenda may have contributed to observed secular trends by placing behavioral risk factors on the social and media agendas. (d) The magnitude of the results of community intervention trials must be judged according to their potential public health or population-level effects. Small changes at the individual level may result in large benefits at the population level. PMID:9611625

    Full Text Available Dana K Bagwell, Robin L WestDepartment of Psychology, University of Florida, Gainesville, FL, USAAbstract: Extensive research on memory interventions has confirmed their success with older adults, but the individual difference factors that predict successful training outcomes remain relatively unexplored. In the current intervention, trainees were identified as active (compliant with training regimens or inactive using trainer ratings based on attendance, homework completion, and class participation. The active group showed significantly greater training-related gains than the inactive group and the control group on most measures. Compliance was predicted by health, education, and self-efficacy. Specifically, active trainees were more likely to have advanced degrees and somewhat higher self-efficacy, and to have higher vitality and fewer functional limitations than the inactive trainees. This research may assist future investigators to target interventions to those who will show the most benefit.Keywords: compliance, memory training, aging, intervention

  2. Antibiotics in interventional radiology

    International Nuclear Information System (INIS)

    The range and number of interventional procedures is rapidly increasing each year. A major complication associated with many procedures is infection, which can result in serious adverse outcomes for the patient. Consequently, antibiotics are amongst the most common pharmaceuticals used by the interventionist, particularly for non-vascular procedures, yet almost no randomized controlled trial data exist to inform our decision when formulating appropriate antibiotic prophylaxis regimens. The purpose of this review is to provide an update on the utilization of antibiotics for common interventional radiology procedures, focusing on timing and duration of antibiotic prophylaxis. - Highlights: • Prophylaxis when necessary should be given immediately prior to the procedure for optimum effect. • Where possible single agents with a narrow spectrum of activity should be used. • Account should be taken of the clinical circumstances of the patient, including surgical history. • Continuous review of agents is necessary, ideally with input from the local microbiology department. • The importance of maximum sterile precautions cannot be overstated

    Advanced medical treatment options have improved pediatric survival but often require invasive vascular procedures or venous access. These procedures increase the risk for thromboembolism in children, and there has been a corresponding increase in the reported incidence of deep venous thrombosis and postthrombotic syndrome in the pediatric population. Percutaneous venous interventions using catheter-directed therapy (CDT), like mechanical thrombectomy and infusion thrombolysis, have been used much less frequently in children, even though they have shown good results in adults. A multidisciplinary team including pediatric hematology, interventional radiology, and intensive care unit is suggested for management of venous thrombosis in children. Indications and contraindications for CDT in children are similar to adults. Mechanical thrombectomy and infusion thrombolysis are some of the more commonly performed treatments. CDT in children requires adapting to patient size and locally available equipment. Ultrasound guidance for access, "cork" technique, appropriate dosing of tissue plasminogen activator for infusion/pharmacomechanical thrombolysis, and simultaneous administration of heparin, plasminogen (fresh frozen plasma), and deficient coagulation factors are some of the important variations of CDT technique in children. Postprocedure monitoring is very important for successful thrombolysis. Retrievable inferior vena cava filters are increasingly being used in children as well, for prophylaxis against pulmonary embolism (PE) if there is a significant risk of PE with/without contraindications to anticoagulation.

    Conservation of wildlife is especially challenging when the targeted species damage crops or livestock, attack humans, or take fish or game. Affected communities may retaliate and destroy wildlife or their habitats. We summarize recommendations from the literature for 13 distinct types of interventions to mitigate these human-wildlife conflicts. We classified eight types as direct (reducing the severity or frequency of encounters with wildlife) and five as indirect (raising human tolerance for encounters with wildlife) interventions. We analyzed general cause-and-effect relationships underlying human-wildlife conflicts to clarify the focal point of intervention for each type. To organize the recommendations on interventions we used three standard criteria for feasibility: cost-effective design, wildlife specificity and selectivity, and sociopolitical acceptability. The literature review and the feasibility criteria were integrated as decision support tools in three multistakeholder workshops. The workshops validated and refined our criteria and helped the participants select interventions. Our approach to planning interventions is systematic, uses standard criteria, and optimizes the participation of experts, policy makers, and affected communities. We argue that conservation action generally will be more effective if the relative merits of alternative interventions are evaluated in an explicit, systematic, and participatory manner.

    The existing literature suggests that theories and models can serve as valuable frameworks for the design and evaluation of health interventions. However, evidence on the use of theories and models in social marketing interventions is sparse. The purpose of this systematic review is to identify to what extent papers about social marketing health interventions report using theory, which theories are most commonly used, and how theory was used. A systematic search was conducted for articles that reported social marketing interventions for the prevention or management of cancer, diabetes, heart disease, HIV, STDs, and tobacco use, and behaviors related to reproductive health, physical activity, nutrition, and smoking cessation. Articles were published in English, after 1990, reported an evaluation, and met the 6 social marketing benchmarks criteria (behavior change, consumer research, segmentation and targeting, exchange, competition and marketing mix). Twenty-four articles, describing 17 interventions, met the inclusion criteria. Of these 17 interventions, 8 reported using theory and 7 stated how it was used. The transtheoretical model/stages of change was used more often than other theories. Findings highlight an ongoing lack of use or underreporting of the use of theory in social marketing campaigns and reinforce the call to action for applying and reporting theory to guide and evaluate interventions.

    Deborah D. DiLiberto

    2015-10-01

    Full Text Available Background: In Uganda, health system challenges limit access to good quality healthcare and contribute to slow progress on malaria control. We developed a complex intervention (PRIME, which was designed to improve quality of care for malaria at public health centres. Objective: Responding to calls for increased transparency, we describe the PRIME intervention's design process, rationale, and final content and reflect on the choices and challenges encountered during the design of this complex intervention. Design: To develop the intervention, we followed a multistep approach, including the following: 1 formative research to identify intervention target areas and objectives; 2 prioritization of intervention components; 3 review of relevant evidence; 4 development of intervention components; 5 piloting and refinement of workshop modules; and 6 consolidation of the PRIME intervention theories of change to articulate why and how the intervention was hypothesized to produce desired outcomes. We aimed to develop an intervention that was evidence-based, grounded in theory, and appropriate for the study context; could be evaluated within a randomized controlled trial; and had the potential to be scaled up sustainably. Results: The process of developing the PRIME intervention package was lengthy and dynamic. The final intervention package consisted of four components: 1 training in fever case management and use of rapid diagnostic tests for malaria (mRDTs; 2 workshops in health centre management; 3 workshops in patient-centred services; and 4 provision of mRDTs and antimalarials when stocks ran low. Conclusions: The slow and iterative process of intervention design contrasted with the continually shifting study context. We highlight the considerations and choices made at each design stage, discussing elements we included and why, as well as those that were ultimately excluded.

    Full Text Available Introduction. We describe our experience of using the Medical Research Council framework on complex interventions to guide the development and evaluation of an intervention to prevent obesity by modifying infant feeding behaviours. Methods. We reviewed the epidemiological evidence on early life risk factors for obesity and interventions to prevent obesity in this age group. The review suggested prevention of excess weight gain in bottle-fed babies and appropriate weaning as intervention targets; hence we undertook systematic reviews to further our understanding of these behaviours. We chose theory and behaviour change techniques that demonstrated evidence of effectiveness in altering dietary behaviours. We subsequently developed intervention materials and evaluation tools and conducted qualitative studies with mothers (intervention recipients and healthcare professionals (intervention deliverers to refine them. We developed a questionnaire to assess maternal attitudes and feeding practices to understand the mechanism of any intervention effects. Conclusions. In addition to informing development of our specific intervention and evaluation materials, use of the Medical Research Council framework has helped to build a generalisable evidence base for early life nutritional interventions. However, the process is resource intensive and prolonged, and this should be taken into account by public health research funders. This trial is registered with ISRTCN: 20814693 Baby Milk Trial.

    Surgical procedures often have the unfortunate side-effect of causing the patient significant trauma while accessing the target site. Indeed, in some cases the trauma inflicted on the patient during access to the target greatly exceeds that caused by performing the therapy. Heart disease has traditionally been treated surgically using open chest techniques with the patient being placed "on pump" - i.e. their circulation being maintained by a cardio-pulmonary bypass or "heart-lung" machine. Recently, techniques have been developed for performing minimally invasive interventions on the heart, obviating the formerly invasive procedures. These new approaches rely on pre-operative images, combined with real-time images acquired during the procedure. Our approach is to register intra-operative images to the patient, and use a navigation system that combines intra-operative ultrasound with virtual models of instrumentation that has been introduced into the chamber through the heart wall. This paper illustrates the problems associated with traditional ultrasound guidance, and reviews the state of the art in real-time 3D cardiac ultrasound technology. In addition, it discusses the implementation of an image-guided intervention platform that integrates real-time ultrasound with a virtual reality environment, bringing together the pre-operative anatomy derived from MRI or CT, representations of tracked instrumentation inside the heart chamber, and the intra-operatively acquired ultrasound images.

    Interventional pulmonology encompasses diagnostic and therapeutic bronchoscopic procedures, and pleural interventions. In the last 10 years older techniques have been refined and exciting new technologies have extended the reach and application of the instruments used. The main areas within pulmonary medicine for which these interventions have a role are malignant and nonmalignant airway disease, pleural effusion, pneumothorax, and artificial airways. There are no data from well-designed prospective trials to guide recommendations for interventional pulmonary procedures in pregnancy. The recommendations provided in this article are based on critical review of reported case series, opinion from recognized experts, and personal observations.

  5. Humanitarian Interventions: a Critical Approach

    Fernando José Ludwig

    2010-11-01

    Full Text Available This paper aims to confront the manifold aspects of “humanitarian” intervention along with the conceptualization of national sovereignty. It is argued that, among the many forms of humanitarian interventions (such as sanctions, material assistance, aid, etc., military intervention should always be the last resort when it comes to guaranteeing both the protection of human rights and regional stability. The discussion about intervention in a sovereign state has long been an inherently part of international studies. On one hand we have the Westphalian concept of sovereignty (therefore, the state-centrism perspective and the absolute rejection of external intervention without consent, and on the other hand, the consolidation of the concept of human rights, advocating that interventions are necessary where human abuses are practised. Merging them in order to verify the legitimacy of humanitarian intervention in a contemporary world has been the real challenge to many scholars in the field. It is argued that humanitarian intervention has very often been used as a fundamental key to serve transnational elites (within developed countries to impose their universal values. In spite of this, it is imperative to bear in mind the multifarious aspects of conflictuality and humanitarian interventions in the light of the past experiences and future challenges.

    The rationale and results for interstitial therapies via interventional MRI in the treatment of tumors in various regions are presented. Different interstitial treatment techniques are presented based on varying technologies both for tumor ablation and treatment monitoring. Data are presented based on 335 patients, 29-84 years of age (mean age 59 years, 196 men and 139 women) with a total of 932 liver tumors, 16 head and neck tumors and 14 abdominal recurrent pelvic and lymphatic tumors. All lesions had been treated with MR-guided laser-induced interstitial thermotherapy (LITT) via 2516 laser applications and 1856 cannulations. Data in the literature are extremely varying depending on author experience, treatment technique, and the included patient material. In our patient material we were able to achieve a local tumor control of 96.7 % depending on the size of the tumorous lesion, the topographical relationship, and the applied laser parameters. The overall cumulative survival rate of patients with liver metastases was 45.74 months (median 40.97 months, 95 % confidence interval 31.42-50.52). The cumulative survival rate of the patient group with hepatic metastases of colorectal carcinoma was 42.71 months (median 39.33 months, 95 % confidence interval 33.26-45.37). In patients with head and neck tumors a relevant reduction in clinically relevant symptoms such as pain, swallowing disorders, or nervous compression was achieved in 11 of 15 patients treated with LITT. In 14 soft tissue tumors, such as pelvic tumor recurrence and lymph node metastases, a local tumor control was obtained in 68 % of lesions. Interstitial therapies under interventional MRI guidance, such as LITT, results in a high local tumor control with an improved survival rate. (orig.) With 7 figs., 28 refs.

    2012-02-01

    Full Text Available The contributors to the Working Group that produced this paper are like countless others who are confronted by programme realities in developing countries, such as the pressure to respond to the challenge of stigma in environments of extreme poverty, the issues of scant resources and the requirements to adapt objectives accordingly, and the competing demands for relief and emergency aid. It is in such contexts that researchers have the responsibility of making evidence-based recommendations and yet, regarding stigma interventions, they are confronted by a domain almost devoid of reliable evidence. Without examples of comparable situations that can be reviewed, it may be possible to make progress only through recourse to theoretical concepts. Broad guidelines, based on respected theories, may prove to be a sound foundation on which intervention programmes can be designed. In this article, the discrete components of stigma that should be targeted in stigma intervention programmes are identified. It is also recommended that since stigma affects different levels in society simultaneously, stigma programmes should be multi-targeted and designed with an intention to adjust interactions between groups at different societal levels. This article lays the foundation for a companion article that presents a generally applicable method by which plans for stigma interventions can be assessed (Interventions for Stigma Reduction – Part 2: Practical Applications. DOI: 10.5463/dcid.v22i3.70

    2016-09-01

    Public policies, population health initiatives, and targeted behavioral change interventions for individuals at risk for developing diabetes are all essential for diabetes prevention in Latin American countries (LACs). This scoping review examines (1) the current evidence on diabetes prevention policies and interventions in LACs to identify components of effective diabetes prevention models in those countries and (2) effective diabetes prevention interventions targeting Latino populations in the USA to explore possible lessons from these interventions for LACs. Diabetes prevention programs in LACs evaluated to date consist of short-term health professional-led face-to-face behavioral counseling sessions. Intervention components of US-based programs for Latinos that might benefit diabetes prevention programs in Latin America include (1) deployment of community health workers ("promotoras") for diabetes screening and delivery of lifestyle modification programs, (2) multiple modes of program delivery beyond face-to-face sessions, (3) information technology to automate and enhance program delivery, (4) leveraging of pre-existing familial relationships to engage in and sustain lifestyle modifications, and (5) innovative environmental change strategies such as collaborations with local food stores and markets to promote healthy behaviors.

    2013-08-01

    Full Text Available Although restraint use has increased primarily in developed countries, vehicle accident-related injuries and deaths continue to be a problem. Alongside lack of restraint use, studies involving suboptimal restraint use have gained recent popularity. In this study we investigate the use of social influence forinterventions to counter emerging suboptimal restraint use in groups of agents.A multi-agent simulation model is provided where dominant individuals use randomly assigned influence rates to repeatedly alter the knowledge of lessinfluential group members. Cultural influence is implemented via a cultural algorithm and used to simulate individuals affected by beliefs in the community. Objectives include investigating the emergence of patterns of restraint selection and use as well as interventions targeted at more influential agents. Results demonstrate that prominent patterns of behaviour similar to the influentialmembers of the groups do emerge. Furthermore, interventions targeted at influential group members outperform interventions targeted at a percentage of the population at large. Interventions succeed at some level both in the presence and absence of cultural influence.

    2014-01-01

    Background The clinical management of intermittent exotropia has been discussed extensively in the literature, yet there remains a lack of clarity regarding indications for intervention, the most effective form of treatment and whether or not there is an optimal time in the evolution of the disease at which any treatment should be carried out. Objectives The objective of this review was to analyse the effects of various surgical and non-surgical treatments in randomised trials of participants with intermittent exotropia, and to report intervention criteria and determine the significance of factors such as age with respect to outcome. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library, Issue 4, 2012), MEDLINE (January 1966 to May 2012), EMBASE (January 1980 to May 2012), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to May 2012), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 4 May 2012. We are no longer searching the UK Clinical Trials Gateway (UKCTG) for this review. We manually searched the British Orthoptic Journal up to 2002, and the proceedings of the European Strabismological Association (ESA), International Strabismological Association (ISA) and American Academy of Paediatric Ophthalmology and Strabismus meeting (AAPOS) up to 2001. We contacted researchers who are active in the field for information about further published or unpublished studies. Selection criteria We included randomised controlled trials of any surgical or non-surgical treatment for intermittent exotropia. Data collection and

    The project for Petrobras in Brazil's Marlim field marked a milestone in the development of remotely operated vehicle (ROV) and remote intervention capabilities. The ability to provide remotely operated intervention support for these deep water operations was the result of a concerted 18-month programme to develop and acquire the necessary technologies. This paper describes that programme. (author)

    An extensive amount of research has demonstrated the effectiveness of psychosocial interventions for children with ADHD. Historically, the research has focused on interventions targeting problems in the home or school setting, but more recent research has highlighted the importance of family – school partnerships and conjoint approaches to intervention involving family and school. Effective approaches to psychosocial intervention consist of strategies to address performance deficits, promote adaptive behavior, and improve children’s self-control and academic and social skills. Considerable evidence exists to indicate that combined approaches are more effective in reducing ADHD symptoms and related academic and social impairments than separate treatments. PMID:22137818

  2. Intervention principles: Theory and practice

    International Nuclear Information System (INIS)

    After the Chernobyl accident, it became clear that some clarification of the basic principles for intervention was necessary as well as more internationally recognised numerical guidance on intervention levels. There was in the former USSR and in Europe much confusion over, and lack of recognition of, the very different origins and purposes of dose limits for controlling deliberate increases in radiation exposure for practices and dose levels at which intervention is prompted to decrease existing radiation exposure. In the latest recommendations from ICRP in its Publication 60, a clear distinction is made between the radiation protection systems for a practice and for intervention. According to ICRP, the protective measures forming a program of intervention, which always have some disadvantages, should each be justified on their own merit in the sense that they should do more good than harm, and their form, scale, and duration should be optimised so as to do the most good. Intervention levels for protective actions can be established for many possible accident scenarios. For planning and preparedness purposes, a generic optimisation based on generic accident scenario calculations, should result in optimised generic intervention levels for each protective measure. The factors entering such an optimisation will on the benefit side include avertable doses and avertable risks as well as reassurance. On the harm side the factors include monetary costs, collective and individual risk for the action itself, social disruption and anxiety. More precise optimisation analyses based on real site and accident specific data can be carried out and result in specific intervention levels. It is desirable that values for easily measurable quantities such as dose rate and surface contamination density be developed as surrogates for intervention levels of avertable dose. However, it is important that these quantities should be used carefully and applied taking account of local

    2015-12-01

    Full Text Available Introduction: Treatment as prevention has mobilized new opportunities in preventing HIV transmission and has led to bold new UNAIDS targets in testing, treatment coverage and transmission reduction. These will require not only an increase in investment but also a deeper understanding of the dynamics of combining behavioural, biomedical and structural HIV prevention interventions. High-income countries are making substantial investments in combination HIV prevention, but is this investment leading to a deeper understanding of how to combine interventions? The combining of interventions involves complexity, with many strategies interacting with non-linear and multiplying rather than additive effects. Discussion: Drawing on a recent scoping study of the published research evidence in HIV prevention in high-income countries, this paper argues that there is a gap between the evidence currently available and the evidence needed to guide the achieving of these bold targets. The emphasis of HIV prevention intervention research continues to look at one intervention at a time in isolation from its interactions with other interventions, the community and the socio-political context of their implementation. To understand and evaluate the role of a combination of interventions, we need to understand not only what works, but in what circumstances, what role the parts need to play in their relationship with each other, when the combination needs to adapt and identify emergent effects of any resulting synergies. There is little development of evidence-based indicators on how interventions in combination should achieve that strategic advantage and synergy. This commentary discusses the implications of this ongoing situation for future research and the required investment in partnership. We suggest that systems science approaches, which are being increasingly applied in other areas of public health, could provide an expanded vocabulary and analytic tools for

    In order to gain entry into cells, diverse viruses, including Ebola virus, SARS-coronavirus and the emerging MERS-coronavirus, depend on activation of their envelope glycoproteins by host cell proteases. The respective enzymes are thus excellent targets for antiviral intervention. In cell culture, activation of Ebola virus, as well as SARS- and MERS-coronavirus can be accomplished by the endosomal cysteine proteases, cathepsin L (CTSL) and cathepsin B (CTSB). In addition, SARS- and MERS-coron...

    The interventional procedures for disk herniation and protrusion by percutaneous techniques are decompressive such as chemodiscolysis with chimopapain, nucleo-discectomy introduced by Onik, LASER discectomy, and recently nucleoplasty, and decompressive and direct antinflammatory such as chemiodiscolysis with an Oxygen-ozone mixture. These techniques have minimized the invasive nature of surgery and avoid or decrease complications like infection linked to surgery. Reducing intervertebral disc size by mechanical aspiration of a part of the disc or partially dissolving the herniation by drying reduces the conic pressure on the torn annulus and creates the space necessary for retropulsion whenever the circular fibres of the annulus regain a minimum capacity to contain the disc under tension. The proposed suggestion in these techniques is that a small change in volume produces large change in pressure. The success rates reported in different studies vary from 65 to 80% of excellent or good results with chemonucleolysis and aspiration. Vertebroplasty (VP) is done by percutaneous injection of acrylic cement (polymethylmetacrylate-PMMA) into the vertebrae under fluoroscopic and/or CT control to achieve an antalgic effect and stabilize the vertebral body. VP has been used for vertebral collapses caused by osteoporosis, long-term steroid treatment, aggressive symptomatic angiomas and lytic metastasis. The reported figures in literature are 80-95% of pain relief, within 7 days after procedure, commonly on the same day.

  7. Interventional neuroradiology (surgical neuroanglography)

    International Nuclear Information System (INIS)

    The applications and effectiveness of surgical neuroangiography, or interventional neuroradiology of the head, neck, spine and brain are rapidly increasing. These procedures are used in the management of a variety of vascular lesions, either preoperatively or as the primary mode of treatment. Lesions that can be approached by the endovascular route, vascular neoplasms (benign or malignant), vasculas malformations (arterial, venous, or mixed), hemangiomas, arteriovenous fistulas, vessel lacerations, and extracranial or intracranial aneurysms are discussed, as are infusion chemotherapy and angioplasties of atherosclerotic or vasospastic extracranial or intracranial vessels. The various catheters or delivery systems and embolic agents, including conventional or special microcatheters, balloon catheters of various lumens, detachable balloons of silicone and latex, open-ended guide wires, and steerable microwires, as well as various embolic agents, either particulated or liquid, and including cytotoxic agents, are described. Functional vascular anatomy of the collateral circulation is reviewed, including extracerebral to intracerebral anastomases and the supply to the transcranial nerves. The use of chemical testing with Amytal and Xylocaine and electrophysiologic monitoring for safe embolization is demonstrated

    Full Text Available Abstract Background With the growing recognition that patients and partners react to a cancer diagnosis as an interdependent system and increasing evidence that psychosocial interventions can be beneficial to both patients and partners, there has been a recent increase in the attention given to interventions that target couples. The aim of this systematic review was to identify existing couple-based interventions for patients with cancer and their partners and explore the efficacy of these interventions (including whether there is added value to target the couple versus individuals, the content and delivery of couple-based interventions, and to identify the key elements of couple-based interventions that promote improvement in adjustment to cancer diagnosis. Method A systematic review of the cancer literature was performed to identify experimental and quasi-experimental couple-based interventions published between 1990 and 2011. To be considered for this review, studies had to test the efficacy of a psychosocial intervention for couples affected by cancer. Studies were excluded if they were published in a language other than English or French, focused on pharmacological, exercise, or dietary components combined with psychosocial components, or did not assess the impact of the intervention on psychological distress (e.g., depression, anxiety or quality of life. Data were extracted using a standardised data collection form, and were analysed independently by three reviewers. Results Of the 709 articles screened, 23 were included in this review. Couple-based interventions were most efficacious in improving couple communication, psychological distress, and relationship functioning. Interventions had a limited impact on physical distress and social adjustment. Most interventions focused on improving communication and increasing understanding of the cancer diagnosis within couples. Interventions were most often delivered by masters-level nurses or

    Full Text Available Introduction: Cardiovascular disease (CVD is a burden for developing countries, yet few CVD intervention studies have been conducted in developing countries such as Indonesia. This paper outlines the process of designing a community intervention programme to reduce CVD risk factors, and discusses experiences with regard to design issues for a small-scale intervention. Design process: The design process for the present community intervention consisted of six stages: (1 a baseline risk factor survey, (2 design of a small-scale intervention by using both baseline survey and qualitative data, (3 implementation of the small-scale intervention, (4 evaluation of the small-scale intervention and design of a broader CVD intervention in the Yogyakarta municipality, (5 implementation of the broader intervention and 6 evaluation of the broader CVD intervention. According to the baseline survey, 60% of the men were smokers, more than 30% of the population had insufficient fruit and vegetable intake and more than 30% of the population were physically inactive, this is why a small-scale population intervention approach was chosen, guided both by the findings in the quantitative and the qualitative study. Experiences: A quasi-experimental study was designed with a control group and pre- and post-testing. In the small-scale intervention, two sub-districts were selected and randomly assigned as intervention and control areas. Within them, six intervention settings (two sub-villages, two schools and two workplaces and three control settings (a sub-village, a school and a workplace were selected. Health promotion activities targeting the whole community were implemented in the intervention area. During the evaluation, more activities were performed in the low socioeconomic status sub-village and at the civil workplace.

    The public health impact of health behaviour interventions is highly dependent on large-scale implementation. Intermediaries-intervention providers-determine to a large extent whether an intervention reaches the target population, and hence its impact on public health. A cross-sectional study was performed to identify the correlates of intermediaries' intention to implement a computer-tailored physical activity intervention. According to theory, potential correlates are intervention characteristics, organisational characteristics, socio-political characteristics and intermediary characteristics. This study investigated whether intermediary characteristics mediated the association between the intervention, organisational and socio-political characteristics and intention to implement the intervention. Results showed that intervention characteristics (i.e., observability (B = 0.53; p = 0.006); relative advantage (B = 0.79; p = 0.020); complexity (B = 0.80; p responsibility (B = 0.66; p ≤ 0.001); capacity (B = 0.83; p social support received by intermediary organisations (B = 0.81; p strategy. Since self-efficacy and social norms perceived by the intermediary organisations partially mediated the effects of other variables on intention to implement the intervention (varying between 29% and 84%), these factors should be targeted to optimise the effectiveness of the implementation strategy.

    In Saxony, the consequences of demographic aging are observable already today. To manage the implications on the health sector, the Saxon Health Targets Steering Committee decided in March 2008 to develop a health target "Active Aging - Aging in Health, Autonomy, and Participation". Target development was based on a 7-level approach (fields of action, main goals, target areas, targets, strategies, intervention measures, indicators for evaluation). A quantitative content analysis was used to reveal 10 potential relevant fields of action, three of which were selected for target development. Targets were developed by 53 stakeholders in multiprofessional working groups. Criteria-based analyses were performed to assure appropriate scientific evidence and feasibility of targets and intervention measures. Over a period of 9 months, 24 targets were defined referring to the main goals "needs-based health care structures", "multiprofessional qualification", "self-rated health" and "intergenerational solidarity". Thirteen targets were developed into recommendations for specific intervention measures. Most of the proposed interventions aim to modify health-related structures or psychosocial determinants of health in the elderly. The best recommendations for intervention measures shall be implemented in cooperation with interested decision-makers. PMID:19565198

  13. Patient doses in interventional cardiology

    International Nuclear Information System (INIS)

    Cardiovascular diseases are the first cause of death in Spain. The most usual procedures in interventional cardiology are coronariography and PTCA. The first is a diagnostic technique, and the second one is interventional. Our goal has been to study procedures made during the first six months in the Interventional Cardiology Unit of the Juan Ramon Jimenez Hospital (Huelva-Spain), taking into account radiation protection issues. We have studied 178 patients; 145 of them underwent coronariography, and 33 of the patients had PTCA too. Every case was analyzed taking into account technical and dosimetric parameters. We show parameters values gathered: Diagnostic techniques (valvular and non-valvular patients), and interventional techniques (coronariography and PTCA in different or in the same intervention). Higher doses were obtained with valvular patients, although the number of frames was similar. Attending to therapeutic procedures, the highest values were gotten with the 'double' interventions. Interventional procedures exceed in 60% doses gotten in diagnostic studies: this is because of the number of series and number of frames per series. Similar values obtained by other authors have been gotten. (author)

    Full Text Available Abstract Background To develop more efficient programmes for promoting dietary and/or physical activity change (in order to prevent type 2 diabetes it is critical to ensure that the intervention components and characteristics most strongly associated with effectiveness are included. The aim of this systematic review of reviews was to identify intervention components that are associated with increased change in diet and/or physical activity in individuals at risk of type 2 diabetes. Methods MEDLINE, EMBASE, CINAHL, PsycInfo, and the Cochrane Library were searched for systematic reviews of interventions targeting diet and/or physical activity in adults at risk of developing type 2 diabetes from 1998 to 2008. Two reviewers independently selected reviews and rated methodological quality. Individual analyses from reviews relating effectiveness to intervention components were extracted, graded for evidence quality and summarised. Results Of 3856 identified articles, 30 met the inclusion criteria and 129 analyses related intervention components to effectiveness. These included causal analyses (based on randomisation of participants to different intervention conditions and associative analyses (e.g. meta-regression. Overall, interventions produced clinically meaningful weight loss (3-5 kg at 12 months; 2-3 kg at 36 months and increased physical activity (30-60 mins/week of moderate activity at 12-18 months. Based on causal analyses, intervention effectiveness was increased by engaging social support, targeting both diet and physical activity, and using well-defined/established behaviour change techniques. Increased effectiveness was also associated with increased contact frequency and using a specific cluster of "self-regulatory" behaviour change techniques (e.g. goal-setting, self-monitoring. No clear relationships were found between effectiveness and intervention setting, delivery mode, study population or delivery provider. Evidence on long

    Radiation-induced skin injuries to patients in interventional procedures have been reported since the early 1990's, but the number reported is far less than what might be occurring around the world. There is a gross lack of awareness resulting in patients suffering. A case of severe injury observed in multiple percutaneous coronary interventions for chronic total occlusion is reported in this paper. Further, the paper summarises the existing knowledge on radiation dosimetry in interventional procedures, factors involved in skin injury, guidance on detection, and avoidance and management of injury when it occurs. Information on a recently launched international anonymous reporting system of the International Atomic Energy Agency is also included. (authors)

    Pain is a significant burden for patients with cancer and is particularly prevalent among those with advanced cancer. Appropriate interventional cancer pain therapies complement conventional pain management by reducing the need for systemic opioid therapy and its associated toxicity; however, these therapies are often underutilized. This article reviews techniques, indications, complications, and outcomes of the most common interventional approaches for the management of cancer-related pain. These approaches include intrathecal drug delivery, vertebral augmentation, neurolysis of the celiac, superior hypogastric and ganglion impar plexus', image-guided tumor ablation, and other less commonly performed but potentially beneficial interventions.

    Paediatric interventional radiology plays a cornerstone role in the management of paediatric trauma. In the acute setting, interventional radiology techniques allow minimally invasive control of haemorrhage or re-establishment of blood flow. Percutaneous stenting and drainage can allow disruptions in urinary or biliary systems to heal without the need for further surgery. Interventional radiology techniques also have a significant role in treating delayed complications of trauma, including embolization of arterial pseudoaneurysms and pulmonary embolism prophylaxis in individuals immobilized due to the trauma or its operative treatment.

    The objective of this study is to understand the pathways through which social influence at the family level moderates the impact of childhood obesity interventions. We conducted a systematic review of obesity interventions in which parents' behaviours are targeted to change children's obesity outcomes, because of the potential social and environmental influence of parents on the nutrition and physical activity behaviours of children. PubMed (1966-2013) and the Web of Science (1900-2013) were searched, and 32 studies satisfied our inclusion criteria. Results for existing mechanisms that moderate parents' influence on children's behaviour are discussed, and a causal pathway diagram is developed to map out social influence mechanisms that affect childhood obesity. We provide health professionals and researchers with recommendations for leveraging family-based social influence mechanisms to increase the efficacy of obesity intervention programmes. © 2016 World Obesity.

    The present study examined the effectiveness of self-help (SH) interventions for individuals with anxiety problems. Thirty-three studies, targeting a variety of anxiety disorders and problems, met criteria for inclusion with 1,582 clinical and subclinical participants. Self-help formats included books, audio/videotapes, and computer/Internet-based programs. The average effect sizes (Cohen's ds) comparing SH interventions to control groups for target symptoms were .62 at posttreatment and .51 at follow-up. When compared to therapist-directed interventions (TDIs), the average effect sizes (Cohen's ds) for target problems were -.42 at posttreatment and -.36 at follow-up. Format of SH materials, type of target disorder, presence of minimal therapist contact, and other study parameters were examined for their effect on treatment outcome. The results were discussed from the perspective of a stepped-care approach for anxiety problems. PMID:16942965

    Various therapeutic interventions have been used in the management of children with cerebral palsy. Traditional physiotherapy and occupational therapy are widely used interventions and have been shown to be of benefit in the treatment of cerebral palsy. Evidence in support of the effectiveness of the neurodevelopmental treatment is equivocal at best. There is evidence to support the use and effectiveness of neuromuscular electrical stimulation in children with cerebral palsy. The effectiveness of many other interventions used in the treatment of cerebral palsy has not been clearly established based on well-controlled trials. These include: sensory integration, body-weight support treadmill training, conductive education, constraint-induced therapy, hyperbaric oxygen therapy, and the Vojta method. This article provides an overview of salient aspects of popular interventions used in the management of children with cerebral palsy. PMID:16391455

    International Nuclear Information System (INIS)

    Considerations about the relation between benefit and expenses are also gaining increasing importance in interventional radiology. This review aims at providing a survey about the published data concerning economical analyses of some of the more frequently employed interventions in radiology excluding neuroradiological and coronary interventions. Because of the relative scarcity of literature in this field, all identified articles (n=46) were included without selection for methodological quality. For a number of radiological interventions the cost-effectiveness has already been demonstrated, e.g., PTA of femoropopliteal and iliac artery stenoses, stenting of renal artery stenoses, placement of vena-cava filters, as well as metal stents in malignant biliary and esophageal obstructions. Conflicting data exist for the treatment of abdominal aortic aneurysms. So far, no analysis could be found that directly compares bypass surgery versus PTA+stent in iliac arteries. (orig.)

    BACKGROUND: Cerebrovascular intervention is a medical strategy to diagnose and treat cerebrovascular disease by intravascular intervention techniques. With the continual developments of computer technology, imageology, and angiography, cerebrovascular intervention techniques have developed rapidly.OBJECTIVE: To summarize and to evaluate vascular imaging diagnostic techniques, vascular intra-arterial thrombolysis, vascular intra-arterial angioplasty, and vascular embolization in clinical applications.RETRIEVAL STRATEGY: An online search was conducted in PubMed for English language reports, published from January 2002 to January 2008, containing the key words: intervention therapy, cerebral vascular disease, endovascular intervention and angioplasty. A total of 57 publications were identified. Inclusion criteria: articles about cerebrovascular intervention for cerebrovascular disease; articles published either in high impact factor journals or in recent years. Exclusion criteria: duplicated articles.LITERATURE EVALUATION: 30 articles were identified concerning intravascular intervention techniques and arterial angioplasty. Of those, 7 articles were reviews and 23 were clinical or basic studies.DATA SYNTHESIS: Carotid artery and basilar artery stenosis were important etiological factors for ischemic cerebrovascular disease. The mechanism of stenosis induction included atherosclerotic plaque exfoliation and stenosis could cause hemodynamic changes to induce cerebral infarction. Therefore, the treatment of carotid artery and basilar artery stenosis played a key role in preventing ischemic cerebral infarction. The international organization for subarachnoid hemorrhage aneurysm has conclusively shown that both relative and absolute risk factors of intravascular embolotherapy were reduced compared to those of surgical occlusion, demonstrating the important role of vascular embolization for the treatment of intracranial aneurysm. Endovascular stents were placed into the

    Models of influenza transmission have focused on the ability of vaccination, antiviral therapy, and social distancing strategies to mitigate epidemics. Influenza transmission, however, may also be interrupted by hygiene interventions such as frequent hand washing and wearing masks or respirators. We apply a model of influenza disease transmission that incorporates hygiene and social distancing interventions. The model describes population mixing as a Poisson process, and the probability of in...

    Recently, human papilloma virus has been implicated to cause several throat and oral cancers and hpv is established to cause most cervical cancers. A human papilloma virus vaccine has been proven successful to reduce infection incidence in FDA clinical trials and it is currently available in the United States. Current intervention policy targets adolescent females for vaccination; however, the expansion of suggested guidelines may extend to other age groups and males as well. This research takes a first step towards automatically predicting personal beliefs, regarding health intervention, on the spread of disease. Using linguistic or statistical approaches, sentiment analysis determines a texts affective content. Self-reported HPV vaccination beliefs published in web and social media are analyzed for affect polarity and leveraged as knowledge inputs to epidemic models. With this in mind, we have developed a discrete-time model to facilitate predicting impact on the reduction of HPV prevalence due to arbitrary age and gender targeted vaccination schemes.

    Full Text Available Abstract Background Insufficient PA has been shown to cluster with other CVD risk factors including insufficient fruit and vegetable intake, overweight, increased serum cholesterol concentrations and elevated blood pressure. This paper describes the development of Working on Wellness (WOW, a worksite intervention program incorporating motivational interviewing by wellness specialists, targeting employees at risk. In addition, we describe the evaluation the effectiveness of the intervention among employees at increased risk for cardiovascular disease. Methods The intervention mapping (IM protocol was used in the planning and design of WOW. Focus group discussions and interviews with employees and managers identified the importance of addressing risk factors for CVD at the worksite. Based on the employees’ preference for individual counselling, and previous evidence of the effectiveness of this approach in the worksite setting, we decided to use motivational interviewing as part of the intervention strategy. Thus, as a cluster-randomised, controlled control trial, employees at increased risk for CVD (N = 928 will be assigned to a control or an intervention group, based on company random allocation. The sessions will include motivational interviewing techniques, comprised of two face-to-face and four telephonic sessions, with the primary aim to increase habitual levels of PA. Measures will take place at baseline, 6 and 12 months. Secondary outcomes include changes in nutritional habits, serum cholesterol and glucose concentrations, blood pressure and BMI. In addition, healthcare expenditure and absenteeism will be measured for the economic evaluation. Analysis of variance will be performed to determine whether there were significant changes in physical activity habits in the intervention and control groups at 6 and 12 months. Discussion The formative work on which this intervention is based suggests that the strategy of targeting

    Currently, chemotherapy is an accredited, standard treatment for unresectable, advanced pancreatic cancer (PC). However, it has been still showed treatment-resistance and followed dismal prognosis in many cases. Therefore, some sort of new, additional treatments are needed for the better therapeutic results for advanced PC. According to the previous reports, it is obvious that interventional endoscopic ultrasonography (EUS) is a well-established, helpful and low-risky procedure in general. As the additional treatments of the conventional therapy for advanced PC, many therapeutic strategies, such as immunotherapies, molecular biological therapies, physiochemical therapies, radioactive therapies, using siRNA, using autophagy have been developing in recent years. Moreover, the efficacy of the other potential therapeutic targets for PC using EUS-fine needle injection, for example, intra-tumoral chemotherapeutic agents (paclitaxel, irinotecan), several ablative energies (radiofrequency ablation and cryothermal treatment, neodymium-doped yttrium aluminum garnet laser, high-intensity focused ultrasound), etc., has already been showed in animal models. Delivering these promising treatments reliably inside tumor, interventional EUS may probably be indispensable existence for the treatment of locally advanced PC in near future. PMID:26677434

  2. Endovascular interventions for multiple trauma

    International Nuclear Information System (INIS)

    In recent years interventional radiology has significantly changed the management of injured patients with multiple trauma. Currently nearly all vessels can be reached within a reasonably short time with the help of specially preshaped catheters and guide wires to achieve bleeding control of arterial und venous bleeding. Whereas bleeding control formerly required extensive open surgery, current interventional methods allow temporary vessel occlusion (occlusion balloons), permanent embolization and stenting. In injured patients with multiple trauma preinterventional procedural planning is performed with the help of multidetector computed tomography whenever possible. Interventional radiology not only allows minimization of therapeutic trauma but also a considerably shorter treatment time. Interventional bleeding control has developed into a standard method in the management of vascular trauma of the chest and abdomen as well as in vascular injuries of the upper and lower extremities when open surgical access is associated with increased risk. Additionally, pelvic trauma, vascular trauma of the superior thoracic aperture and parenchymal arterial lacerations of organs that can be at least partially preserved are primarily managed by interventional methods. In an interdisciplinary setting interventional radiology provides a safe and efficient means of rapid bleeding control in nearly all vascular territories in addition to open surgical access. (orig.)

    Intervention analysis techniques are described for identifying and statistically modelling trends which may be present in water quality time series. At the exploratory data analysis stage, simple graphical and modelling methods can be employed for visually detecting and examining trends in a time series caused by one or more external interventions. For instance, a plot of a robust locally weighted regression smooth through a graph of the observations over time may reveal trends and other interesting statistical properties contained in the time series. In addition, statistical tests, such as different versions of the nonparametric Mann-Kendall test, can be used to detect the presence of trends caused by unknown or known external interventions. To characterize rigorously and estimate trends which may be known in advance or else detected using exploratory data analysis studies, different parametric methods can be utilized at the confirmatory data analysis stage. Specifically, the time series modelling approach to intervention analysis can be employed to estimate the magnitudes of the changes in the mean level of the series due to the interventions. Particular types of regression models can also be used for estimating trends, especially when there are many missing observations. To demonstrate how intervention analysis methods can be effectively used in environmental impact assessment, representative applications to water quality time series are presented. PMID:24243172

    Interventions to reduce college student drinking, although efficacious, generally yield only small effects on behavior change. Examining mechanisms of change may help to improve the magnitude of intervention effects by identifying effective and ineffective active ingredients. Informed by guidelines for establishing mechanisms of change, we conducted a systematic review of alcohol interventions for college students to identify (a) which constructs have been examined and received support as mediators, (b) circumstances that enhance the likelihood of detecting mediation, and (c) the extent of evidence for mechanisms of change. We identified 61 trials that examined 22 potential mediators of intervention efficacy. Descriptive norms consistently mediated normative feedback interventions. Motivation to change consistently failed to mediate motivational interviewing interventions. Multiple active ingredient interventions were not substantially more likely to find evidence of mediation than single ingredient interventions. Delivering intervention content remotely reduced likelihood of finding support for mediation. With the exception of descriptive norms, there is inadequate evidence for the psychosocial constructs purported as mechanisms of change in the college drinking literature. Evidence for mechanisms will be yielded by future studies that map all active ingredients to targeted psychosocial outcomes and that assess potential mediators early, inclusively, and at appropriate intervals following interventions.

    Cyberbullying is an emerging form of bullying that takes place through contemporary information and communication technologies. Building on past research on the psychosocial risk factors for cyberbullying in this age group, the present study assessed a theory-driven, school-based preventive intervention that targeted moral disengagement, empathy and social cognitive predictors of cyberbullying. Adolescents (N = 355) aged between 16 and 18 years were randomly assigned into the intervention and the control group. Both groups completed anonymous structured questionnaires about demographics, empathy, moral disengagement and cyberbullying-related social cognitive variables (attitudes, actor prototypes, social norms, and behavioral expectations) before the intervention, post-intervention and 6 months after the intervention. The intervention included awareness-raising and interactive discussions about cyberbullying with intervention group students. Analysis of covariance (ANCOVA) showed that, after controlling for baseline measurements, there were significant differences at post-intervention measures in moral disengagement scores, and in favorability of actor prototypes. Further analysis on the specific mechanisms of moral disengagement showed that significant differences were observed in distortion of consequences and attribution of blame. The implications of the intervention are discussed, and guidelines for future school-based interventions against cyberbullying are provided. PMID:26350445

    Full Text Available Abstract Background We describe the use of a conceptual framework and implementation protocol to prepare effective health services interventions for implementation in community-based (i.e., non-academic-affiliated settings. Methods The framework is based on the experiences of the U.S. Centers for Disease Control and Prevention (CDC Replicating Effective Programs (REP project, which has been at the forefront of developing systematic and effective strategies to prepare HIV interventions for dissemination. This article describes the REP framework, and how it can be applied to implement clinical and health services interventions in community-based organizations. Results REP consists of four phases: pre-conditions (e.g., identifying need, target population, and suitable intervention, pre-implementation (e.g., intervention packaging and community input, implementation (e.g., package dissemination, training, technical assistance, and evaluation, and maintenance and evolution (e.g., preparing the intervention for sustainability. Key components of REP, including intervention packaging, training, technical assistance, and fidelity assessment are crucial to the implementation of effective interventions in health care. Conclusion REP is a well-suited framework for implementing health care interventions, as it specifies steps needed to maximize fidelity while allowing opportunities for flexibility (i.e., local customizing to maximize transferability. Strategies that foster the sustainability of REP as a tool to implement effective health care interventions need to be developed and tested.

    for tailoring family treatments to target family processes specific to each disorder. Investigators such as Patterson and Liddle have invested great effort in rigorously dismantling the treatment process, identifying and refining essential ingredients, and repackaging more potent treatment protocols. This process has paid off well. Programmatic treatment development is needed for many disorders to address myriad questions. What are the essential disorder-specific family processes that should be targeted by interventions? Hostility, criticism, communication, attachment and autonomy, attributional sets, and behavior management are important processes of family life, but each may have more relative importance for specific disorders. With a greater understanding of these processes, treatments could be tailored to target these mechanisms more efficiently and effectively. (ABSTRACT TRUNCATED) PMID:11449817

    Full Text Available Abstract Background To date, mental health problems and mental workload have been increasingly related to long-term sick leave and disability. However, there is, as yet, no structured protocol available for the identification and application of an intervention for stress-related mental health problems at the workplace. This paper describes the structured development, implementation and planning for the evaluation of a return-to-work intervention for sick-listed employees with stress-related mental disorders (SMDs. The intervention is based on an existing successful return-to-work intervention for sick-listed employees with low back pain. Methods The principles of Intervention Mapping were applied to combine theory and evidence in the development, implementation and planning for the evaluation of a participatory workplace intervention, aimed at an early return-to-work for sick-listed employees with SMDs. All stakeholders were involved in focus group interviews: i.e. employees recently sick-listed with SMDs, supervisors and occupational health professionals. Results The development of the participatory workplace intervention according to the Intervention Mapping principles resulted in a structured return-to-work intervention, specifically tailored to the needs of sick-listed employees with SMDs. Return-to-work was proposed as a behavioural change, and the Attitude – Social influence – self-Efficacy model was identified as a theoretical framework. Stakeholder involvement in focus group interviews served to enhance the implementation. The cost-effectiveness of the intervention will be evaluated in a randomised controlled trial. Conclusion Intervention Mapping was found to be a promising method to develop interventions tailored to a specific target group in the field of occupational health. Trial registration ISRCTN92307123

  10. Molecular Targets for Targeted Radionuclide Therapy

    International Nuclear Information System (INIS)

    Molecular targeted radionuclide cancer therapy is becoming of increasing importance, especially for disseminated diseases. Systemic chemotherapies often lack selectivity while targeted radionuclide therapy has important advantages as the radioactive cytotoxic unit of the targeting vector is specifically directed to the cancer, sparing normal tissues. The principle strategy to improve cancer selectivity is to couple therapeutic agents to tumour-targeting vectors. In targeted radionuclide therapy (TRT), the cytotoxic portion of the conjugates normally contains a therapeutic radiometal immobilised by a bifunctional chelator. The aim is therefore to use as ligand-targeted therapeutics vectors coupled to Auger-, alpha- and/or beta-emitting radionuclides. An advantage of using radiation instead of chemotherapeutics as the cytotoxic agent is the so called 'crossfire effect'. This allows sterilisation of tumour cells that are not directly targeted due to heterogeneity in target molecule expression or inhomogeneous vector delivery. However, before the targeting ligands can be selected, the target molecule on the tumour has to be selected. It should be uniquely expressed, or at least highly overexpressed, on or in the target cells relative to normal tissues. The target should be easily accessible for ligand delivery and should not be shed or down- regulated after ligand binding. An important property of a receptor (or antigen) is its potential to be internalized upon binding of the ligand. This provides an active uptake mechanism and allows the therapeutic agent to be trapped within the tumour cells. Molecular targets of current interest include: Receptors: G-protein coupled receptors are overexpressed on many major human tumours. The prototype of these receptors are somatostatin receptors which show very high density in neuroendocrine tumours, but there are many other most interesting receptors to be applied for TRT. The targeting ligands for these receptors are

  17. Correlates of the Intention to Implement a Tailored Physical Activity Intervention: Perceptions of Intermediaries

    Directory of Open Access Journals (Sweden)

    2014-02-01

    Full Text Available The public health impact of health behaviour interventions is highly dependent on large-scale implementation. Intermediaries—intervention providers—determine to a large extent whether an intervention reaches the target population, and hence its impact on public health. A cross-sectional study was performed to identify the correlates of intermediaries’ intention to implement a computer-tailored physical activity intervention. According to theory, potential correlates are intervention characteristics, organisational characteristics, socio-political characteristics and intermediary characteristics. This study investigated whether intermediary characteristics mediated the association between the intervention, organisational and socio-political characteristics and intention to implement the intervention. Results showed that intervention characteristics (i.e., observability (B = 0.53; p = 0.006; relative advantage (B = 0.79; p = 0.020; complexity (B = 0.80; p < 0.001; compatibility (B = 0.70; p < 0.001, organisational characteristics (i.e., type of organization (B = 0.38; p = 0.002; perceived task responsibility (B = 0.66; p ≤ 0.001; capacity (B = 0.83; p < 0.001, and the social support received by intermediary organisations (B = 0.81; p < 0.001 were associated with intention to implement the intervention. These factors should thus be targeted by an implementation strategy. Since self-efficacy and social norms perceived by the intermediary organisations partially mediated the effects of other variables on intention to implement the intervention (varying between 29% and 84%, these factors should be targeted to optimise the effectiveness of the implementation strategy.

    Human noroviruses are major causative agents of sporadic and epidemic gastroenteritis both in children and adults. Currently there are no licensed therapeutic intervention measures either in terms of vaccines or drugs available for these highly contagious human pathogens. Genetic and antigenic diversity of these viruses, rapid emergence of new strains, and their ability to infect a broad population by using polymorphic histo-blood group antigens for cell attachment, pose significant challenges for the development of effective antiviral agents. Despite these impediments, there is progress in the design and development of therapeutic agents. These include capsid-based candidate vaccines, and potential antivirals either in the form of glycomimetics or designer antibodies that block HBGA binding, as well as those that target essential non-structural proteins such as the viral protease and RNA-dependent RNA polymerase. In addition to these classical approaches, recent studies suggest the possibility of interferons and targeting host cell factors as viable approaches to counter norovirus infection. This review provides a brief overview of this progress. PMID:27318434

From a practical standpoint, this raises an important yet unanswered question: What is the optimal price index to target? This paper derives the optimal price level targeting index defined over the eight main components of the Consumer Price Index. It finds that such an index places a heavier weight, relative to the expenditure weight, on sectors with slow price adjustments....

    This study analyzes the accuracy of forecasted target prices within analysts’ reports. We compute a measure for target price forecast accuracy that evaluates the ability of analysts to exactly forecast the ex-ante (unknown) 12-month stock price. Furthermore, we determine factors that explain this accuracy. Target price accuracy is negatively related to analyst-specific optimism and stock-specific risk (measured by volatility and price-to-book ratio). However, target price accuracy is positive...

    An important question that firms face in advertising is developing effective media strategy. Major improvements in the quality of consumer information and the growth of targeted media vehicles allow firms to precisely target advertising to consumer segments within a market. This paper examines advertising strategy when competing firms can target advertising to different groups of consumers within a market. With targeted advertising, we find that firms advertise more to consumers who have a st...

    Review of the community-based CVD intervention programs suggests that a number of components have been successful using varying methods and materials for CVD risk reduction. It should be noted, however, that in multi-intervention programs it is often difficult to determine which components of the intervention were responsible for the overall success of the study. The community-based approach to CVD prevention is generalizable, cost-effective (because of the use of mass communication methods), and has the potential for modifying the environment and influencing health policies. Based on the experiences and successes of a number of community projects, recommendations have been proposed for developing future programs. Although they are not totally comprehensive, it has been suggested that a community-based intervention program should consider the following recommendations: 1) An understanding of the community: the needs and priorities of the community should be assessed, and close collaboration with individuals from the community, including community leaders, opinion leaders, community health care providers, and community organizations from various sectors of the community, should be consulted. Efforts should be focused on underserved and vulnerable populations. 2) Inclusion of community activities: these activities should be integrated within the context of the community environment, including primary health care services, voluntary organizations, grocery stores, restaurants, work sites, schools, and local media. 3) Inclusion mass media messages: the mass media can provide information and reinforcement of the behavior change. 4) Develop cost-effective interventions to assure that the community is exposed to an effective dose of the intervention. 5) Work with community organizations to help change social and physical environments to make them more conducive to health and healthy life-styles changes. 6) Develop a reliable monitoring and evaluation system: monitor the

  9. Occupational exposure in interventional radiology

    International Nuclear Information System (INIS)

    This study was conducted to survey of radiation safety control and to measure occupational radiation exposure dose of staff in interventional radiology in Korea. Interventioanl radiology requires the operator and assisting personnel to remain close to the patient, and thus close to primary beams of radiation. Therefore exposure doses of these personnel are significant from a radiological protection point of view. We surveyed the status of radiation safety on interventional radiology of 72 hospitals. The result were that 119 radiation equipments are using in interventional radiology and 744 staffs are composed of 307 radiologists, 116 residents of radiology, 5 general physicians, 171 radiologic technologists and 145 nurses. 81.4% and 20.2 % of operating physicians are using neck collar protector and goggle respectively. The average radiation dose was measured 0.46±0.15 mSv/10 hours fluoroscopy inside examination room in radiation protection facilities. Occupational radiation exposure data on the staff were assessed in interventional radiology procedures from 8 interventional radiology equipments of 6 university hospitals. The dose measurements were made by placing a thermoluminesent dosimeter(TLD) on various body surface of operation and assistant staff during actual interventional radiology. The measured points were the corner of the eyes, neck(on the thyroid) , wrists, chest(outside and inside of the protector), and back. Average radiation equivalent dose of the corner of left eye and left wrist of operating physicians were 1.19 mSv(0.11∼4.13 mSv)/100 minutes fluoroscopy and 4.32 mSv(0.16∼11.0 mSv)/100 minutes fluoroscopy respectively. Average exposure dose may vary depending on the type of procedure, personal skills and the quality of equipment. These results will be contributed to prepare the guide line in interventional radiology in Korea

    Full Text Available Abstract Background The registration of clinical trials has been promoted to prevent publication bias and increase research transparency. Despite general agreement about the minimum amount of information needed for trial registration, we lack clear guidance on descriptions of non-pharmacologic interventions in trial registries. We aimed to evaluate the quality of registry descriptions of non-pharmacologic interventions assessed in ongoing randomized controlled trials (RCTs of patient education. Methods On 6 May 2009, we searched for all ongoing RCTs registered in the 10 trial registries accessible through the World Health Organization International Clinical Trials Registry Platform. We included trials evaluating an educational intervention (that is, designed to teach or train patients about their own health and dedicated to participants, their family members or home caregivers. We used a standardized data extraction form to collect data related to the description of the experimental intervention, the centers, and the caregivers. Results We selected 268 of 642 potentially eligible studies and appraised a random sample of 150 records. All selected trials were registered in 4 registers, mainly ClinicalTrials.gov (61%. The median [interquartile range] target sample size was 205 [100 to 400] patients. The comparator was mainly usual care (47% or active treatment (47%. A minority of records (17%, 95% CI 11 to 23% reported an overall adequate description of the intervention (that is, description that reported the content, mode of delivery, number, frequency, duration of sessions and overall duration of the intervention. Further, for most reports (59%, important information about the content of the intervention was missing. The description of the mode of delivery of the intervention was reported for 52% of studies, the number of sessions for 74%, the frequency of sessions for 58%, the duration of each session for 45% and the overall duration for 63

  20. Interventional magnetic resonance imaging - non-invasive imaging for interventions

    International Nuclear Information System (INIS)

    As a prerequisite for MR-guidance of interventional procedures, instruments have to be well depicted in the MR image without obscuring or distorting the underlying anatomy. For non-vascular interventions the imaging speed has to be in the range of seconds while control of vascular interventions requires real time imaging speed. The imaging contrast has to be maintained as well as a high spatial resolution. Furthermore, sufficient patient access has to be provided by the MR scanner. Neither an ideal magnet nor the optimal single sequence are available to fulfill the above-mentioned criteria. The type of sequence - gradient echo versus spin echo - together with changing of the echo time and phase encording direction will ensure an appropriate size of the artifact and thereby of the appearance of the instrument in the MR image. The feasibility of non-vascular MR-guided interventions has been proved at field strengths ranging from 0.064 T to 1.5 T. Bone biopsies, soft tissue biopsies, drainages, and control of interstitial thermo- and cryotherapy have been reported. For vascular interventions, different real time MR strategies are currently under investigation. The development of dedicated catheters and guide wires has enabled MR-guided dilatations, stenting, placement of vena cava filters, and TIPS procedures. Considering the fast progress being made in this field, there can be no question that interventional MRI will become a well-accepted clinical tool offering potential advantages such as excellent soft tissue contrast, multiplanar imaging, flow measurements, high resolution imaging of vessel walls, and lack of ionizing radiation.
