    There is a growing number of Internet-based approaches that offer young people screening for sexually transmitted infections. This paper explores young men's views towards the barriers and facilitators of implementing an Internet-based screening approach. The study sought to consider ways in which the proposed intervention would reach and engage men across ages and socioeconomic backgrounds. This qualitative study included 15 focus groups with 60 heterosexual young men (aged 16-24 years) across central Scotland, drawn across age and socioeconomic backgrounds. Focus groups began by obtaining postcode data to allocate participants to a high/low deprivation category. Focus group discussions involved exploration of men's knowledge of chlamydia, use of technology, and views toward Internet-based screening. Men were shown sample screening invitation letters, test kits, and existing screening websites to facilitate discussions. Transcripts from audio recordings were analyzed with "Framework Analysis". Men's Internet and technology use was heterogeneous in terms of individual practices, with greater use among older men (aged 20-24 years) than teenagers and some deprivation-related differences in use. We detail three themes related to barriers to successful implementation: acceptability, confidentiality and privacy concerns, and language, style, and content. These themes identify ways Internet-based screening approaches may fail to engage some men, such as by raising anxiety and failing to convey confidentiality. Men wanted screening websites to frame screening as a serious issue, rather than using humorous images and text. Participants were encouraged to reach a consensus within their groups on their broad design and style preferences for a screening website; this led to a set of common preferences that they believed were likely to engage men across age and deprivation groups and lead to greater screening uptake. The Internet provides opportunities for re-evaluating how we

    The objective of the Get Tested Why Not campaign is to increase access to chlamydia and gonorrhea testing and sexual health information, with specific focus on youth. Individuals between the ages of 15-29 are most affected by chlamydia and gonorrhea infections in Ottawa and were identified as the target population. Youth from the target population were engaged in the development and launch of the campaign. Development of the campaign began in 2009 and led to a launch on March 21, 2011. Social media promotion as well as traditional advertising approaches developed awareness of the campaign within the target population. The campaign consists of a bilingual, youth-friendly website and texting service. After assessing appropriateness of testing, clients can download a requisition form for urine-based chlamydia and gonorrhea testing and submit a sample at one of 26 laboratories across Ottawa. During year 1 of the campaign, there were 13,385 website hits and 104 specimens submitted for chlamydia and gonorrhea testing. The majority (57.6%, n=60) of requisitions were submitted by members of the target population (age 15-29). Of the requisitions submitted, 95 (91.3%) were negative, 4 (3.9%) were positive and 5 (4.8%) were cancelled due to lab errors. The campaign is reaching the target population and has demonstrated a positive impact on knowledge and intended behaviours of users. The use of technology has expanded testing options, thereby potentially broadening Ottawa Public Health's reach to clients who may be less likely to test through traditional testing approaches.

    Full Text Available Abstract Background Chlamydia trachomatis is an obligate intracellular bacterial parasite, which causes several severe and debilitating diseases in humans. This study uses comparative genomic analyses of 12 complete published C. trachomatis genomes to assess the contribution of recombination and selection in this pathogen and to understand the major evolutionary forces acting on the genome of this bacterium. Results The conserved core genes of C. trachomatis are a large proportion of the pan-genome: we identified 836 core genes in C. trachomatis out of a range of 874-927 total genes in each genome. The ratio of recombination events compared to mutation (ρ/θ was 0.07 based on ancestral reconstructions using the ClonalFrame tool, but recombination had a significant effect on genetic diversification (r/m = 0.71. The distance-dependent decay of linkage disequilibrium also indicated that C. trachomatis populations behaved intermediately between sexual and clonal extremes. Fifty-five genes were identified as having a history of recombination and 92 were under positive selection based on statistical tests. Twenty-three genes showed evidence of being under both positive selection and recombination, which included genes with a known role in virulence and pathogencity (e.g., ompA, pmps, tarp. Analysis of inter-clade recombination flux indicated non-uniform currents of recombination between clades, which suggests the possibility of spatial population structure in C. trachomatis infections. Conclusions C. trachomatis is the archetype of a bacterial species where recombination is relatively frequent yet gene gains by horizontal gene transfer (HGT and losses (by deletion are rare. Gene conversion occurs at sites across the whole C. trachomatis genome but may be more often fixed in genes that are under diversifying selection. Furthermore, genome sequencing will reveal patterns of serotype specific gene exchange and selection that will generate important

    Koekenbier Rik H

    2010-10-01

    Full Text Available Abstract Background Implementing Chlamydia trachomatis screening in the Netherlands has been a point of debate for several years. The National Health Council advised against implementing nationwide screening until additional data collected from a pilot project in 2003 suggested that screening by risk profiles could be effective. A continuous increase in infections recorded in the national surveillance database affirmed the need for a more active approach. Here, we describe the rationale, design, and implementation of a Chlamydia screening demonstration programme. Methods A systematic, selective, internet-based Chlamydia screening programme started in April 2008. Letters are sent annually to all 16 to 29-year-old residents of Amsterdam, Rotterdam, and selected municipalities of South Limburg. The letters invite sexually active persons to login to http://www.chlamydiatest.nl with a personal code and to request a test kit. In the lower prevalence area of South Limburg, test kits can only be requested if the internet-based risk assessment exceeds a predefined value. Results We sent invitations to 261,025 people in the first round. One-fifth of the invitees requested a test kit, of whom 80% sent in a sample for testing. The overall positivity rate was 4.2%. Conclusions This programme advances Chlamydia control activities in the Netherlands. Insight into the feasibility, effectiveness, cost-effectiveness, and impact of this large-scale screening programme will determine whether the programme will be implemented nationally.

    The Internet has become a regular part of daily life for the majority of people in many parts of the world. It now offers an additional means of effecting changes to behaviour such as smoking. To determine the effectiveness of Internet-based interventions for smoking cessation. We searched the Cochrane Tobacco Addiction Group Specialized Register, with additional searches of MEDLINE, EMBASE, CINAHL, PsycINFO, and Google Scholar. There were no restrictions placed on language of publication or publication date. The most recent search was in June 2010. We included randomized and quasi-randomized trials. Participants were people who smoked, with no exclusions based on age, gender, ethnicity, language or health status. Any type of Internet-based intervention was eligible. The comparison condition could be a no-intervention control or a different Internet site or programme. Methodological and study quality details were extracted using a standardised form. We selected smoking cessation outcomes at short term (one to three months) and long term (6 months or more) follow up, and reported study effects as a risk ratio with 95% confidence intervals. Only limited meta-analysis was performed, as the heterogeneity of the data for populations, interventions and outcomes allowed for very little pooling. Twenty trials met the inclusion criteria. There were more female than male participants. Some Internet programmes were intensive and included multiple outreach contacts with participants, whilst others relied on participants to initiate and maintain use.Ten trials compared an Internet intervention to a non-Internet based smoking cessation intervention or to a no intervention control. Six of these recruited adults, one recruited young adult university students and three recruited adolescents. Two trials of the same intensive automated intervention in populations of adult who smoked showed significantly increased cessation compared to printed self-help materials at 12 months. In one

    Calgary Laboratory Services, Alberta, Canada, provides microbiology services via a centralized laboratory to the Calgary Health Region. A selective genital Chlamydia trachomatis (CT)/Neisseria gonorrhoeae (GC) testing policy for women >35 years was implemented. The changes in physician ordering practice, the rate of detection of infections, and the test turnaround times were monitored. The volume of tests, the cost/test, and the total service costs accrued in the year before and after this policy change were compared. An immediate impact was a 30% decrease in tests performed due to the laboratory rejecting samples from older women. Subsequently, physicians' practice changed so that tests were ordered when test criteria were met. Detection rates did not change in any age group. A 27.9% decrease in the total service costs resulted in a labor reduction of 0.2 FTE. Selective testing of women >35 years with a low prevalence of CT/GC infection is clinically relevant and cost-effective.

    Avian chlamydiosis is a zoonotic disease occurring in humans, poultry, and exotic birds. It has been suggested that some wild bird species play an important role as reservoirs for Chlamydia, especially Chlamydia psittaci. Whereas C. psittaci is the predominant chlamydial agent in birds, in the present study we have determined the prevalence of different species of Chlamydia among selected wild bird species in Poland using a rapid and sensitive real-time PCR method. In total, 369 free-living birds from 35 bird species and 15 orders were examined. Samples from 27 birds (7.3%) were positive for chlamydial DNA in the PCR; 22 positive samples (81.5%) belonged to C. psittaci, three to Chlamydia trachomatis (11.1%), and two (7.4%) classified only to the genus Chlamydia. Most of C. psittaci-positive samples belonged to five orders: Anseriformes, Columbiformes, Gruiformes, Phasianiformes, and Passeriformes. All C. trachomatis samples were obtained from Eurasian coots (Gruiformes). Two Chlamydia-positive samples not classified to any Chlamydia species were obtained from a common wood pigeon (Columbiformes) and a common buzzard (Accipitriformes). Detection of C. psittaci and C. trachomatis in free-living bird populations force to think on significance of birds as reservoir of varied Chlamydia species and their epidemiological importance.

    Internet-based carbon calculators have the potential to be powerful tools for helping people to understand their personal energy use derived from fossil fuels and to take action to reduce the related carbon emissions. This paper reviews twenty-three calculators concluding that in most cases this environmental learning tool is falling short of giving people the ability to accurately monitor their energy use; to receive meaningful feedback and guidance for altering their energy use; or to connect with others also going through the same learning process of saving energy and conserving carbon. This paper presents the findings of research into the accuracy and effectiveness of carbon calculators. Based on the assessment of the calculators the paper discusses the opportunities Internet technology could be offering for engagement, communication, encouragement and guidance on low-carbon lifestyle choices. Finally, recommendations are made for the development of accurate, informative and social Internet-based carbon calculators.

    The core of the computer program STRMDEPL08 that estimates streamflow depletion by a pumping well with one of four analytical solutions was re-written in the Javascript software language and made available through an internet-based interface (web page). In the internet-based interface, the user enters data for one of the four analytical solutions, Glover and Balmer (1954), Hantush (1965), Hunt (1999), and Hunt (2003), and the solution is run for constant pumping for a desired number of simulation days. Results are returned in tabular form to the user. For intermittent pumping, the interface allows the user to request that the header information for an input file for the stand-alone executable STRMDEPL08 be created. The user would add the pumping information to this header information and run the STRMDEPL08 executable that is available for download through the U.S. Geological Survey. Results for the internet-based and stand-alone versions of STRMDEPL08 are shown to match.

  8. Internet-based instruction in college teaching

    Flickinger, Kathleen Anne

    Distance education and Internet instruction are increasingly being used in college science teaching. In an effort to reach more students, Iowa State University's Human Anatomy and Physiology course was offered via Internet as well as via traditional lecture format. To assess the educational ramifications of this offering, three studies were conducted. In the first study, a collective case study approach was utilized to describe the learning environment created by an Internet-based college science course. In this study, three students were followed as they worked their way through the course. Collective case study methodologies were used to provide a rich description of the learning environment experienced by these students. Motivation, computer savvy, and academic and personal self-confidence appeared to impact the satisfaction level of the students enrolled in the class. To evaluate the effectiveness of the learning environment offered through the Internet-based science course, a quantitative comparison study was undertaken. In this study a comparison of achievement scores and study habits between students enrolled in the Internet-based class and those enrolled in the traditional section was made. Results from this study indicated that content understanding and retention did not appear to be effected by the type of instruction. Desirable study habits were reportedly used more frequently in the Internet section of the class than in the traditional class. To complete the description of the Internet course experience, a qualitative examination of Internet instructors' time commitment and level of teaching satisfaction was conducted. Data for this study consisted of interviews and researcher observations. Instructor time-on-task was initially quite high, and remained above the average spent on average face-to-face instruction in subsequent semesters. Additionally the role of the faculty member changed dramatically, causing some lessening of job satisfaction. Taken as

    : The main limitation of this report is that we relied only on published results. Most of research has been conducted in countries other than Germany. The fulfilment of the criteria for introduction of screening depends on contextual factors. More data from Germany are needed in order to answer the main questions concerning acceptance, use of selection criteria to identify subgroups and economical aspects of screening for Chlamydia trachomatis in Germany. Conclusions: The criteria for introduction of screening for Chlamydia trachomatis are partially fulfilled. The available evidence indicates that the success of a screening programme for Chlamydia trachomatis will depend on the implementation of strategies for uptake enhancement and probably on the participation of men as well. A pilot project should be conducted in order to assess cost-effectiveness, acceptance and feasibility of different screening strategies in Germany. On the light of the available evidence, the inclusion of screening for Chlamydia trachomatis in the benefit basket without embedding it in a multifaceted programme targeting primary prevention of sexually transmitted diseases and participation in screening cannot be recommende.

    Few data exist on potential harms of chlamydia screening. We assessed the psychosocial impact of receiving a positive Chlamydia trachomatis test result. We prospectively studied women ≥16 years of age undergoing chlamydia testing in 2 Midwestern family planning clinics. We surveyed women at baseline and about 1 month after receiving test results, using 9 validated psychosocial scales/subscales and chlamydia-specific questions. Changes in scale scores were calculated for each woman. Mean percent changes in scores for chlamydia-positive and -negative women were compared using a t test. We enrolled 1807 women (response rate, 84%). Of the 1688 women with test results, 149 (8.8%) tested positive. At follow-up, chlamydia-positive women (n = 71) had a 75% increase in anxiety about sexual aspects of their life on the Multidimensional Sexual Self-Concept Questionnaire (P < 0.001), significantly greater than the 26% increase among 280 randomly selected chlamydia-negative women (P = 0.02). There were no differences for the other 8 scales/subscales, including general measures of anxiety, depression, and self-esteem. Chlamydia-positive women were more likely than chlamydia-negative women to be "concerned about chlamydia" (80% vs. 40%, P < 0.001) and to report breaking up with a main partner (33% vs. 11%, P < 0.001) at follow-up. Women testing positive reported a range of chlamydia-specific concerns. Chlamydia-positive women had significant increases in anxiety about sex and concern about chlamydia, but did not have marked changes in more general measures of psychosocial well-being about 1 month after diagnosis. Chlamydia diagnoses were associated with some disruption of relationships with main partners. Chlamydia-specific concerns may guide counseling messages to minimize psychosocial impact.

    Tobacco use is estimated to kill 7 million people a year. Nicotine is highly addictive, but surveys indicate that almost 70% of US and UK smokers would like to stop smoking. Although many smokers attempt to give up on their own, advice from a health professional increases the chances of quitting. As of 2016 there were 3.5 billion Internet users worldwide, making the Internet a potential platform to help people quit smoking. To determine the effectiveness of Internet-based interventions for smoking cessation, whether intervention effectiveness is altered by tailoring or interactive features, and if there is a difference in effectiveness between adolescents, young adults, and adults. We searched the Cochrane Tobacco Addiction Group Specialised Register, which included searches of MEDLINE, Embase and PsycINFO (through OVID). There were no restrictions placed on language, publication status or publication date. The most recent search was conducted in August 2016. We included randomised controlled trials (RCTs). Participants were people who smoked, with no exclusions based on age, gender, ethnicity, language or health status. Any type of Internet intervention was eligible. The comparison condition could be a no-intervention control, a different Internet intervention, or a non-Internet intervention. To be included, studies must have measured smoking cessation at four weeks or longer. Two review authors independently assessed and extracted data. We extracted and, where appropriate, pooled smoking cessation outcomes of six-month follow-up or more, reporting short-term outcomes narratively where longer-term outcomes were not available. We reported study effects as a risk ratio (RR) with a 95% confidence interval (CI).We grouped studies according to whether they (1) compared an Internet intervention with a non-active control arm (e.g. printed self-help guides), (2) compared an Internet intervention with an active control arm (e.g. face-to-face counselling), (3) evaluated the

    The Internet is now an indispensable part of daily life for the majority of people in many parts of the world. It offers an additional means of effecting changes to behaviour such as smoking. To determine the effectiveness of Internet-based interventions for smoking cessation. We searched the Cochrane Tobacco Addiction Group Specialized Register. There were no restrictions placed on language of publication or publication date. The most recent search was conducted in April 2013. We included randomized and quasi-randomized trials. Participants were people who smoked, with no exclusions based on age, gender, ethnicity, language or health status. Any type of Internet intervention was eligible. The comparison condition could be a no-intervention control, a different Internet intervention, or a non-Internet intervention. Two authors independently assessed and extracted data. Methodological and study quality details were extracted using a standardized form. We extracted smoking cessation outcomes of six months follow-up or more, reporting short-term outcomes where longer-term outcomes were not available. We reported study effects as a risk ratio (RR) with a 95% confidence interval (CI). Clinical and statistical heterogeneity limited our ability to pool studies. This updated review includes a total of 28 studies with over 45,000 participants. Some Internet programmes were intensive and included multiple outreach contacts with participants, whilst others relied on participants to initiate and maintain use.Fifteen trials compared an Internet intervention to a non-Internet-based smoking cessation intervention or to a no-intervention control. Ten of these recruited adults, one recruited young adult university students and two recruited adolescents. Seven of the trials in adults had follow-up at six months or longer and compared an Internet intervention to usual care or printed self help. In a post hoc subgroup analysis, pooled results from three trials that compared

    2003-01-01

    This paper describes an Internet based remote experimental setup of a double lined pendulum mechanism for students experiments at the M. Sc. Level. Some of the first year experience using this web-based setup in classes is referred. In most of the courses given at the division of mechanical engineering systems at Linkoeping Institute of Technology we provide experimental setups to enhance the teaching Of M.Sc. students. Many of these experimental setups involve mechatronical systems. Disciplines like fluid power, electronics, and mechanics and also software technologies are used in each experiment. As our campus has recently been split into two different cities some new concepts for distance learning have been studied. The one described here tries to implement remotely controlled mechatronic setups for teaching basic programming of real-time operating systems and analysis of the dynamics of mechanical systems. The students control the regulators for the pendulum through a web interface and get measurement results and a movie back through their email. The present setup uses a double linked pendulum that is controlled by a DC-motor and monitored through both camera and angular position sensors. All software needed is hosted on a double-processor PC running the RedHat 7.1. distribution complemented with real-time scheduling using DIAPM-RTAI 1.7. The Internet site is presented to the students using PHP, Apache and MySQL. All of the used software originates from the open source domain. The experience from integrating these technologies and security issues is discussed together with the web-camera interface. One of the important experiences from this project so far is the need for a good visual feedback. This is both in terms of video speed but also in resolution. It has been noticed that when the students makes misstates and wants to search the failure they want clear, large images with high resolution to support their personal believes in the cause of the failure.

    The aim of this study was to examine the impact on dementia caregivers' experienced stress and health status of 2 Internet-based intervention programs. Ninety-one dementia caregivers were given the choice of being involved in either an Internet-based chat support group or an Internet-based video conferencing support group. Pre-post outcome measures focused on distress, health status, social support, and service utilization. In contrast to the Chat Group, the Video Group showed significantly greater improvement in mental health status. Also, for the Video Group, improvements in self-efficacy, neuroticism, and social support were associated with lower stress response to coping with the care recipient's cognitive impairment and decline in function. The results show that, of 2 Internet-based intervention programs for dementia caregivers, the video conferencing intervention program was more effective in improving mental health status and improvement in personal characteristics were associated with lower caregiver stress response.

  9. Internet based remote cooperative engineering system for NSSS system design

    Kim, Y. S.; Lee, S. L.

    2000-01-01

    Implementation of information technology system through the nuclear power plant life cycle which covers site selection, design, construction, operation and decommission has been suggested continually by the reports or guidelines from NIRMA, INPO, NUMARC, USNRC and EPRI since late 1980's, and some of it has been actually implemented and applied partially to the practical design process. However, for the NSSS system design, a high level activity of nuclear power plant design phase, none of the effects has been reported with regard to implementing the information system. In Korea, KAERI studied NuIDEAS(Nuclear Integrated Database and Design Advancement System) in 1995, and KAERI (Korea Electric Power Research Institute) worked with CENP (Combustion Engineering Nuclear Power) for KNGR IMS(Information Management System) in 1997 as trials to adopt information system for NSSS system design. In this paper, after reviewing the pre-studied two information system, we introduce implementation of the information system for NSSS system design which is compatible with the on-going design works and can be used as means of concurrent engineering through internet. With this electronic design system, we expect increase of the design efficiency and productivity by switching from hard copy based design flow to internet based system. In addition, reliability and traceability of the design data is highly elevated by containing the native document file together with all the review, comment and resolution history in one database

  10. Contingent approach to Internet-based supply network integration

    Ho, Jessica; Boughton, Nick; Kehoe, Dennis; Michaelides, Zenon

    2001-10-01

    The Internet is playing an increasingly important role in enhancing the operations of supply networks as many organizations begin to recognize the benefits of Internet- enabled supply arrangements. However, the developments and applications to-date do not extend significantly beyond the dyadic model, whereas the real advantages are to be made with the external and network models to support a coordinated and collaborative based approach. The DOMAIN research group at the University of Liverpool is currently defining new Internet- enabled approaches to enable greater collaboration across supply chains. Different e-business models and tools are focusing on different applications. Using inappropriate e- business models, tools or techniques will bring negative results instead of benefits to all the tiers in the supply network. Thus there are a number of issues to be considered before addressing Internet based supply network integration, in particular an understanding of supply chain management, the emergent business models and evaluating the effects of deploying e-business to the supply network or a particular tier. It is important to utilize a contingent approach to selecting the right e-business model to meet the specific supply chain requirements. This paper addresses the issues and provides a case study on the indirect materials supply networks.

  11. Using Internet-Based Videos as Pedagogical Tools in the Social Work Policy Classroom

    Directory of Open Access Journals (Sweden)

    Sarabeth Leukefeld

    2011-11-01

    Full Text Available Students often feel disconnected from their introductory social welfare policy courses. Therefore, it is important that instructors employ engaging pedagogical methods in the classroom. A review of the literature reveals that a host of methods have been utilized to attempt to interest students in policy courses, but there is no mention of using internet-based videos in the social welfare policy classroom. This article describes how to select and use appropriate internet-based videos from websites such as YouTube and SnagFilms, to effectively engage students in social welfare policy courses. Four rules are offered for choosing videos based on emotional impact, brevity, and relevance to course topics. The selected videos should elicit students’ passions and stimulate critical thinking when used in concert with instructor-generated discussion questions, writing assignments, and small group dialogue. Examples of the process of choosing videos, discussion questions, and student reactions to the use of videos are provided.

    2016-12-01

    Internet-based interventions have emerged as a new treatment and intervention modality for psychological disorders. Given their features of treatment flexibility, anonymity and confidentiality, this modality may be well suited in the management of addictive behaviours. A systematic literature review of the effectiveness and treatment outcomes of Internet-based interventions for smoking cessation, problematic alcohol use, substance abuse and gambling was performed. Studies were included if they met the following criteria: clients received a structured therapeutic Internet-based intervention for a problematic and addictive behaviour; included more than five clients; effectiveness was based on at least one outcome; outcome variables were measured before and immediately following the interventions; had a follow-up period; and involved at least minimal therapist contact over the course of the program. Sixteen relevant studies were found; nine addressed the effects of Internet-based interventions on smoking cessation, four on gambling, two on alcohol and one on opioid dependence. All studies demonstrated positive treatment outcomes for their respective addictive behaviours. The current review concluded that Internet-based interventions are effective in achieving positive behavioural change through reducing problematic behaviours. This mode of therapy has been found to have the capacity to provide effective and practical services for those who might have remained untreated, subsequently reducing the barriers for help-seekers. This in turn provides imperative information to treatment providers, policy makers, and academic researchers.

    2014-02-01

    Emerging infectious diseases present a complex challenge to public health officials and governments; these challenges have been compounded by rapidly shifting patterns of human behaviour and globalisation. The increase in emerging infectious diseases has led to calls for new technologies and approaches for detection, tracking, reporting, and response. Internet-based surveillance systems offer a novel and developing means of monitoring conditions of public health concern, including emerging infectious diseases. We review studies that have exploited internet use and search trends to monitor two such diseases: influenza and dengue. Internet-based surveillance systems have good congruence with traditional surveillance approaches. Additionally, internet-based approaches are logistically and economically appealing. However, they do not have the capacity to replace traditional surveillance systems; they should not be viewed as an alternative, but rather an extension. Future research should focus on using data generated through internet-based surveillance and response systems to bolster the capacity of traditional surveillance systems for emerging infectious diseases.

    2017-11-28

    The aim of this study was to evaluate the quality and value of web-based information on advance directives. Internet-based information on advance directives was selected because, if it is inaccurate or difficult to understand, patients risk making decisions about their care that may not be followed in practice. Two validated health information evaluation tools, the Suitability Assessment of Materials and DISCERN, and a focus group were used to assess credibility, user orientation and effectiveness. Only one of the 34 internet-based information items on advance directives reviewed fulfilled the study criteria and 30% of the sites were classed as unreadable. In terms of learning and informing, 79% of the sites were considered unsuitable. Using health literacy tools to evaluate internet-based health information highlights that often it is not at a functional literacy level and neither informs nor empowers users to make independent and valid healthcare decisions. ©2017 RCN Publishing Company Ltd.

    2015-04-16

    The aim of the current project was to develop an Internet-based recruitment system for HIV and sexually transmitted infection (STI) screening for men who have sex with men (MSM) in Estonia in order to collect biological samples during behavioural studies. In 2013, an Internet-based HIV risk-behaviour survey was conducted among MSM living in Estonia. After completing the questionnaire, all participants were offered anonymous and free-of-charge STI testing. They could either order a urine sample kit by post to screen for chlamydia infections (including lymphogranuloma venereum (LGV)), trichomoniasis, gonorrhoea and Mycoplasma genitalium infections, or visit a laboratory for HIV, hepatitis A virus, hepatitis B virus,hepatitis C virus and syphilis screening. Of 301 participants who completed the questionnaire, 265 (88%),reported that they were MSM. Of these 265 MSM,68 (26%) underwent various types of testing. In the multiple regression analysis, Russian as the first language,previous HIV testing and living in a city or town increased the odds of testing during the study. Linking Internet-based behavioural data collection with biological sample collection is a promising approach. As there are no specific STI services for MSM in Estonia,this system could also be used as an additional option for anonymous and free-of-charge STI screening.

    Only limited information is available on the presence of Chlamydiaceae in wildlife, a deficit that is particularly acute concerning mammalian wildlife in Africa. In a retrospective analysis of organ material from an earlier study on wild mammals from the Seregenti National Park, 521 samples from 54 animals of 14 mammalian species were investigated. The presence of Chlamydiaceae was analyzed using molecular methods and immunohistochemistry. Chlamydial DNA was detected by real-time polymerase chain reaction in formalin-fixed and paraffin-embedded tissues from large ruminants (African buffaloes, Syncerus caffer, n=4) and a large predator (spotted hyena, Crocuta crocuta, n=1). Microarray results revealed Chlamydia abortus in all cases, confirmed by sequencing of selected samples, and a mixed infection with Chlamydia abortus and Chlamydia pneumoniae in an African buffalo. This is the first report of Chlamydiaceae in African wildlife of the Serengeti area.

    combinations of instructions to guide behavior change and barrier identification (n=5). The design and aim of the included studies did not permit determining exactly which component and/or behavior change technique was more efficacious in producing positive outcomes in caregivers. The risk for selection bias was low for all the studies, and low to high for performance, detection, and attrition biases. In sum, Internet-based interventions that incorporate professional and social support, and provide instructions to change behavior and problem solve in an interactive manner appear to lead to positive outcomes in caregivers. Studies isolating the specific effect of components are needed to improve our understanding of the underlying mechanism of action. ©Cassioppée Guay, Claudine Auger, Louise Demers, W Ben Mortenson, William C Miller, Dominique Gélinas-Bronsard, Sara Ahmed.

    There is a growing need for patient education and an evaluation of its outcomes. The aim of this study was to compare ambulatory orthopaedic surgery patients' knowledge with Internet-based education and face-to-face education with a nurse. The following hypothesis was proposed: Internet-based patient education (experiment) is as effective as face-to-face education with a nurse (control) in increasing patients' level of knowledge and sufficiency of knowledge. In addition, the correlations of demographic variables were tested. The patients were randomized to either an experiment group (n = 72) or a control group (n = 75). Empirical data were collected with two instruments. Patients in both groups showed improvement in their knowledge during their care. Patients in the experiment group improved their knowledge level significantly more in total than those patients in the control group. There were no differences in patients' sufficiency of knowledge between the groups. Knowledge was correlated especially with patients' age, gender and earlier ambulatory surgeries. As a conclusion, positive results concerning patients' knowledge could be achieved with the Internet-based education. The Internet is a viable method in ambulatory care.

    Full Text Available It is widely established debriefing in business games is important and influences the students' learning performance. Most games only support game statistics instead of explaining solution paths. We suggest the automatic generation of explanations for internet-mediated business games to improve the debriefing quality. As a proof of concept we developed a prototype of an internet-based auction game embedding an open simulation model and an automatic explanation component helping students and teachers to analyse the decision making process. This paper describes the usefulness of automated explanations and the underlying generic software architecture.

    Full Text Available Abstract Background The advent of urine testing for Chlamydia trachomatis has raised the possibility of large-scale screening for this sexually transmitted infection, which is now the most common in the United Kingdom. The purpose of this study was to investigate the effect of an invitation to be screened for chlamydia and of receiving a negative result on levels of anxiety, depression and self-esteem. Methods 19,773 men and women aged 16 to 39 years, selected at random from 27 general practices in two large city areas (Bristol and Birmingham were invited by post to send home-collected urine samples or vulvo-vaginal swabs for chlamydia testing. Questionnaires enquiring about anxiety, depression and self-esteem were sent to random samples of those offered screening: one month before the dispatch of invitations; when participants returned samples; and after receiving a negative result. Results Home screening was associated with an overall reduction in anxiety scores. An invitation to participate did not increase anxiety levels. Anxiety scores in men were lower after receiving the invitation than at baseline. Amongst women anxiety was reduced after receipt of negative test results. Neither depression nor self-esteem scores were affected by screening. Conclusion Postal screening for chlamydia does not appear to have a negative impact on overall psychological well-being and can lead to a decrease in anxiety levels among respondents. There is, however, a clear difference between men and women in when this reduction occurs.

    2012-11-01

    The ubiquity of the Internet has led to the widespread availability of health-related information to the public, and the subsequent empowerment of patients has fundamentally altered the patient-physician relationship. Among several concerns of physicians is the possibility that patients may be misinformed by information obtained from the Internet. One opportunity for health care providers to address this problem exists within Internet-based patient education materials (IPEMs). According to recent research in Otolaryngology-Head and Neck Surgery, IPEMs found within professional otolaryngology websites are written at the 8th- to 18th-grade reading comprehension level, essentially unchanged over the past 3 years. This greatly exceeds the fourth- to sixth-grade reading level recommended by the National Institutes of Health. Benefits, strategies, and challenges to improving the readability of IPEMs are discussed.

    2013-09-01

    The transition through adolescence places adolescents at increased risk of depression, yet care-seeking in this population is low, and treatment is often ineffective. In response, we developed an Internet-based depression prevention intervention (CATCH-IT) targeting at-risk adolescents. We explore CATCH-IT program costs, especially safety costs, in the context of an Accountable Care Organization as well as the perceived value of the Internet program. Total and per-patient costs of development were calculated using an assumed cohort of a 5,000-patient Accountable Care Organization. Total and per-patient costs of implementation were calculated from grant data and the Medicare Resource-Based Relative Value Scale (RBRVS) and were compared to the willingness-to-pay for CATCH-IT and to the cost of current treatment options. The cost effectiveness of the safety protocol was assessed using the number of safety calls placed and the percentage of patients receiving at least one safety call. The willingness-to-pay for CATCH-IT, a measure of its perceived value, was assessed using post-study questionnaires and was compared to the development cost for a break-even point. We found the total cost of developing the intervention to be USD 138,683.03. Of the total, 54% was devoted to content development with per patient cost of USD 27.74. The total cost of implementation was found to be USD 49,592.25, with per patient cost of USD 597.50. Safety costs accounted for 35% of the total cost of implementation. For comparison, the cost of a 15-session group cognitive behavioral therapy (CBT) intervention aimed at at-risk adolescents was USD 1,632 per patient. Safety calls were successfully placed to 96.4% of the study participants. The cost per call was USD 40.51 with a cost per participant of USD 197.99. The willingness-to-pay for the Internet portion of CATCH-IT had a median of USD 40. The break-even point to offset the cost of development was 3,468 individuals. Developing Internet-based

    In this online study we examined the retention of recent personal events using an Internet-based diary technique. Each participant (N=878) recorded on a website one recent personal event and was contacted after a retention interval that ranged between 2 and 46 days. We investigated how well the participants could recall the content, time, and details of their recorded event. We found a classic retention function. Details of the events were forgotten more rapidly than the content and the time of the events. There were no differences between the forgetting rates of the "who", "what" and "where" elements of the content component. Reminiscing, social sharing, pleasantness, and frequency of occurrence aided recall, but surprisingly importance and emotionality did not. They were, however, strongly associated with reminiscing and social sharing.

    Within the last few years, a host of value-based metrics like EVA, MVA, TBR, CFORI, and TSR have evolved. This paper attempts to analyze the validity and applicability of EVA and Balanced Scorecard for Internet based organizations. Despite the collapse of the dot-com model, the firms engaged in e- commerce continue to struggle to find new ways to account for customer-base, technology, employees, knowledge, etc, as part of the value of the firm. While some metrics, like the Balance Scorecard are geared towards internal use, others like EVA are for external use. Value-based metrics are used for performing internal audits as well as comparing firms against one another; and can also be effectively utilized by individuals outside the firm looking to determine if the firm is creating value for its stakeholders.

  5. Serological diagnosis of Chlamydia infections: proposal of a cost-effective approach

    2008-06-01

    Full Text Available Infections caused by genus Chlamydia are challenging for phisicians, as a results of a complicated pathogenesis and a variable clinical picture. Furthermore, potential sequelae following Chlamydia trachomatis, Chlamydia pneumoniae, Chlamydia psittaci infections are of clinical relevant interest. Serodiagnosis is a clue tool when the direct antigen research or the bacteria fragments detection is impaired. Some serological tests such as the ELISA or the indirect micro-immunofluorescence methods are routinely performed. To improve the diagnostic efficiency of these tests, a selective coating of specie-specific reactive antigens on microwells or on microscopic slides is proposed.A highly selective coating is essential to generate a specific immune response for each Chlamydia species and high levels of distinct IgA, IgG, IgM antibody classes.The goal of serology is the diagnostic value of results, therefore the correct choice of the best screening and confirmation test is of extreme relevance due to the clinical impact of results for the therapeutical approach and management of acute and chronic infections. In conclusion, a quantitative specific anti-Chlamydia IgG and IgA antibody detection is a useful method to improve the follow up of complicated chronic clinical sequelae.

    Quality of life (QoL) measurement relies upon participants providing meaningful responses, but not all respondents may pay sufficient attention when completing self-reported QoL measures. This study examined the impact of careless responding on the reliability and validity of Internet-based QoL assessments. Internet panelists (n = 2000) completed Patient-Reported Outcomes Measurement Information System (PROMIS®) short-forms (depression, fatigue, pain impact, applied cognitive abilities) and single-item QoL measures (global health, pain intensity) as part of a larger survey that included multiple checks of whether participants paid attention to the items. Latent class analysis was used to identify groups of non-careless and careless responders from the attentiveness checks. Analyses compared psychometric properties of the QoL measures (reliability of PROMIS short-forms, correlations among QoL scores, "known-groups" validity) between non-careless and careless responder groups. Whether person-fit statistics derived from PROMIS measures accurately discriminated careless and non-careless responders was also examined. About 7.4% of participants were classified as careless responders. No substantial differences in the reliability of PROMIS measures between non-careless and careless responder groups were observed. However, careless responding meaningfully and significantly affected the correlations among QoL domains, as well as the magnitude of differences in QoL between medical and disability groups (presence or absence of disability, depression diagnosis, chronic pain diagnosis). Person-fit statistics significantly and moderately distinguished between non-careless and careless responders. The results support the importance of identifying and screening out careless responders to ensure high-quality self-report data in Internet-based QoL research.

    A substantial amount of consumer health-related information is available on the Internet. Studies suggest that consumer comprehension may be compromised if content exceeds a 7th-grade reading level, which is the average American reading level identified by the United States Department of Health and Human Services (USDHHS). To determine the readability of Internet-based consumer health information offered by organizations that represent the top 5 medical-related causes of death in America. We hypothesized that the average readability (reading grade level) of Internet-based consumer health information on heart disease, cancer, stroke, chronic obstructive pulmonary disease, and diabetes would exceed the USDHHS recommended reading level. From the Web sites of the American Heart Association, American Cancer Society, American Lung Association, American Diabetes Association, and American Stroke Association we randomly gathered 100 consumer-health-information articles. We assessed each article with 3 readability-assessment tools: SMOG (Simple Measure of Gobbledygook), Gunning FOG (Frequency of Gobbledygook), and Flesch-Kincaid Grade Level. We also categorized the articles per the USDHHS readability categories: easy to read (below 6th-grade level), average difficulty (7th to 9th grade level), and difficult (above 9th-grade level). Most of the articles exceeded the 7th-grade reading level and were in the USDHHS "difficult" category. The mean +/- SD readability score ranges were: SMOG 11.80 +/- 2.44 to 14.40 +/- 1.47, Flesch-Kincaid 9.85 +/- 2.25 to 11.55 +/- 0.76, and Gunning FOG 13.10 +/- 3.42 to 16.05 +/- 2.31. The articles from the American Lung Association had the lowest reading-level scores with each of the readability-assessment tools. Our findings support that Web-based medical information intended for consumer use is written above USDHHS recommended reading levels. Compliance with these recommendations may increase the likelihood of consumer comprehension.

  8. Efficacy of interventions to increase the uptake of chlamydia screening in primary care: a systematic review

    Full Text Available Abstract Background As most genital chlamydia infections are asymptomatic, screening is the main way to detect and cases for treatment. We undertook a systematic review of studies assessing the efficacy of interventions for increasing the uptake of chlamydia screening in primary care. Methods We reviewed studies which compared chlamydia screening in the presence and the absence of an intervention. The primary endpoints were screening rate or total tests. Results We identified 16 intervention strategies; 11 were randomised controlled trials and five observational studies, 10 targeted females only, five both males and females, and one males only. Of the 15 interventions among females, six were associated with significant increases in screening rates at the 0.05 level including a multifaceted quality improvement program that involved provision of a urine jar to patients at registration (44% in intervention clinics vs. 16% in the control clinic; linking screening to routine Pap smears (6.9% vs. 4.5%, computer alerts for doctors (12.2% vs. 10.6%; education workshops for clinic staff; internet-based continuing medical education (15.5% vs. 12.4%; and free sexual health consultations (16.8% vs. 13.2%. Of the six interventions targeting males, two found significant increases including the multifaceted quality improvement program in which urine jars were provided to patients at registration (45% vs. 15%; and the offering by doctors of a test to all presenting young male clients, prior to consultation (29 vs. 4%. Conclusions Interventions that promoted the universal offer of a chlamydia test in young people had the greatest impact on increasing screening in primary care.

    Terho, P

    1978-01-01

    Chlamydia trachomatis was isolated from 58.5% of 159 patients with non-specific urethritis (NSU) using irradiated McCoy cell cultures. Patients with persistent Chlamydia-positive NSU remained Chlamydia-positive each time they were examined before treatment and patients with Chlamydia-negative NSU remained Chlamydia-negative during the course of the illness. Neither the duration of symptoms of urethritis nor a history of previous urethritis affected the chlamydial isolation rate significantly. Of 40 patients with severe discharge 30 (75%) harboured C. trachomatis. One-third of the Chlamydia-positive patients had a severe urethral discharge, while this was present in only 15% of Chlamydia-negative patients. Complications--such as conjunctivitis, arthritis, and epididymitis--were more severe in men with Chlamdia-positive NSU than in those with Chlamydia-negative NSU. Of 64 men matched for sexual promiscuity but without urethritis, none harboured C. trachomatis in his urethra. This differs significantly (P less than 0.001) when compared with patients with NSU. C. trachomatis was isolated from the urogenital tract in 24 (42%) out of 57 female sexual contacts of patients with NSU. The presence of C. trachomatis in the women correlated significantly (P less than 0.001) with the isolation of the agent from their male contacts. These findings give further evidence for the aetiological role of C. trachomatis in non-specific urethritis and its sexual transmission. PMID:678958

    2018-05-30

    Resilience is associated with a positive and resource-oriented perspective. Therefore, it seems especially attractive for health promotion and prevention. In recent years, interventions to foster resilience have been increasingly developed, which train resilience factors and are mainly conducted in a face to face group format. The question is raised what potential internet-based interventions (i-interventions) that train resilience factors have for health promotion and prevention. Based on a narrative overview, the possibilities for i‑interventions that train resilience factors for health promotion and prevention are investigated and the state of research is described. The effects of the i‑interventions presented here, which aim at fostering resilience, on measures of mental health and well-being are heterogeneous and vary between low to high effects. Stronger evidence for the efficacy of these measures exists for more general i‑interventions that also train resilience factors but are conceptualized for the prevention of specific disorders, such as depression or for stress reduction. Given the heterogeneous nature of intervention contents, theoretical foundations and therapeutic methods used, the heterogeneity of the evidence is discussed. In addition, perspectives for the further development of resource-oriented resilience interventions are outlined.

  14. A robust internet-based auction to procure electricity forwards

    International Nuclear Information System (INIS)

    Woo, C.K.; Lloyd, D.; Borden, M.; Warrington, R.; Baskette, C.

    2004-01-01

    Securing forward contracts to manage procurement-cost risk is an intuitively appealing and economically reasonable strategy for a load-serving local distribution company (LDC) in today's volatile electricity marketplace. However, knowing what to buy does not guarantee least-cost implementation. The forward-contract price quoted by a prospective seller may not be the 'best deal' that an LDC could have obtained, especially when the forward contract desired by the LDC is not actively traded. This paper reports the results from five internet-based auctions for electricity forward contracts with non-firm delivery and varying hourly quantities held monthly by a Florida municipal utility (MU) from September 2002 to January 2003. The results confirm that a multi-round auction design is robust in realizing competitive price offers made by credit-worthy sellers, time-efficient contracting, and consistent cost savings to the MU. Thus, the Anglo-Dutch auction described herein is a reasonable substitute for generation ownership by an LDC. (author)

    2008-11-01

    Full Text Available This article aims at giving an example of how practical, clinical knowledge can be explored by the use of a tailor-made Information and Communication Technology (ICT-tool: Physio-Net. In constructing content to this particular internet- based resource used for bachelor students at Tromsø University College, a clinician expert physiotherapist contributed with a detailed analysis of her own practice and its underpinning rationale, displayed by film and text simultaneously. The clinician was interviewed about how the work had affected later practice and why, and her experiences are discussed in terms of reflective practice. Internalised ways of thinking and acting were changed; she became more aware of the importance of taking the patient’s perspective, of the interaction in the situation, and made more careful conclusions in the clinical reasoning process. Time, observation, writing and guidance were important clues to this learning process and outcome. It is concluded that looking into one’s own practice amongst “critical friends”, mediated in a transparent mode as the Internet tool provides, constitutes a valuable learning potential for the individual and might contribute towards making professional practice more open and easier to discuss and develop.

    Many patients suffering from trichotillomania (TTM) have never undergone treatment. Without treatment, TTM often presents with a chronic course. Characteristics of TTM individuals who have never been treated (untreated) remain largely unknown. Whether treatment history impacts Internet-based interventions has not yet been investigated. We aimed to answer whether Internet-based interventions can reach untreated individuals and whether treatment history is associated with certain characteristics and impacts on the outcome of an Internet-based intervention. We provided Internet-based interventions. Subjects were characterized at three time points using the Massachusetts General Hospital Hairpulling Scale, Hamilton Depression Rating Scale, and the World Health Organization Quality of Life questionnaire. Of 105 individuals, 34 were untreated. Health-related quality of life (HRQoL) was markedly impaired in untreated and treated individuals. Symptom severity did not differ between untreated and treated individuals. Nontreatment was associated with fewer depressive symptoms ( P =0.002). Treatment history demonstrated no impact on the outcome of Internet-based interventions. Results demonstrate that Internet-based interventions can reach untreated TTM individuals. They show that untreated individuals benefit as much as treated individuals from such interventions. Future Internet-based interventions should focus on how to best reach/support untreated individuals with TTM. Additionally, future studies may examine whether Internet-based interventions can reach and help untreated individuals suffering from other psychiatric disorders.

    Internet-based technologies are increasingly being used for research studies. However, it is not known whether Internet-based approaches will effectively engage participants from diverse racial and socioeconomic backgrounds. A total of 967 participants were recruited and offered genetic ancestry results. We evaluated viewing Internet-based genetic ancestry results among participants who expressed high interest in obtaining the results. Of the participants, 64% stated that they were very or extremely interested in their genetic ancestry results. Among interested participants, individuals with a high school diploma (n = 473) viewed their results 19% of the time relative to 4% of the 145 participants without a diploma (P Internet-based research was low despite high reported interest. This suggests that explicit strategies should be developed to increase diversity in Internet-based research.Genet Med 19 2, 240-243.

  3. Genital Chlamydia trachomatis: An update

    Directory of Open Access Journals (Sweden)

    Meenakshi Malhotra

    2013-01-01

    Full Text Available Chlamydia trachomatis is the most common cause of curable bacterial sexually transmitted infection (STI worldwide. It manifests primarily as urethritis in males and endocervicitis in females. Untreated chlamydial infection in man can cause epididymitis and proctitis. Though most women with Chlamydia infection are asymptomatic or have minimal symptoms, some develop salpingitis, endometritis, pelvic inflammatory disease (PID, ectopic pregnancy and tubal factor infertility. It is associated with an increased risk for the transmission or acquisition of HIV and is also attributed to be a risk factor for the development of cervical carcinoma. Early diagnosis and treatment of infected individuals is required to prevent the spread of the disease and severe sequelae. Traditionally, tissue culture was considered the gold standard for the diagnosis. However, with the availability of newer diagnostic techniques particularly molecular methods which are not only highly sensitive and specific but are cost-effective also, the diagnosis has became fast and easy. The purpose of this review is to study the various aspects of genital C. trachomatis infection. Also the advances related to the clinical picture, various diagnostic modalities, prevention, treatment, drug resistance and control measures will be dealt with.

The experience of creation the Internet-based information system of digital geological data providing, and also previous works, including the developing of web-service of NGKIS-system, allows to tell, that technological realization of presenting Russian geological-cartographical data with using of international standards is possible. While realizing, it could be some difficulties, associated with geological material depth. Russian informational geological model is more deep and wide, than foreign. This means the main problem of using international standards and formats: Russian geological data presentation is possible only with decreasing the data detalisation. But, such a problem becomes not very important, if the service publishes also Russian vocabularies, not associated with international vocabularies. In this case, the international format could be the interchange format to change data between Russian users. The integration into the international projects reaches developing of the correlation schemes between Russian and foreign classificators and vocabularies.

    Internet-based interventions are more cost-effective than conventional interventions and can provide immediate, easy-to-access, and individually tailored support for behavior change. Waist circumference is a strong predictor of an increased risk for a host of diseases, such as hypertension, diabetes, and dyslipidemia, independent of body mass index. To date, no study has examined the effect of Internet-based lifestyle interventions on waist circumference change. This study aimed to systematically review the effect of Internet-based interventions on waist circumference change among adults. This meta-analysis reviewed randomized controlled trials (N=31 trials and 8442 participants) that used the Internet as a main intervention approach and reported changes in waist circumference. Internet-based interventions showed a significant reduction in waist circumference (mean change -2.99 cm, 95% CI -3.68 to -2.30, I(2)=93.3%) and significantly better effects on waist circumference loss (mean loss 2.38 cm, 95% CI 1.61-3.25, I(2)=97.2%) than minimal interventions such as information-only groups. Meta-regression results showed that baseline waist circumference, gender, and the presence of social support in the intervention were significantly associated with waist circumference reduction. Internet-based interventions have a significant and promising effect on waist circumference change. Incorporating social support into an Internet-based intervention appears to be useful in reducing waist circumference. Considerable heterogeneity exists among the effects of Internet-based interventions. The design of an intervention may have a significant impact on the effectiveness of the intervention.

    Full Text Available BACKGROUND: Evidences support the possible involvement of microorganisms such as Chlamydia pneumonia in the pathogenesis of ischemic heart diseases through a chronic inflammatory process. The aim of this study was to determine the relation between Chlamydia pneumoniae seropositivity with acute myocardial infarction and its related risk factors.    METHODS: In this case-control study, 88 patients admitted in CCU with a diagnosis of acute coronary syndrome, without a history of chronic diseases including cancers were selected as cases and 49 surgical patients without an evidence of cardiovascular disease according to clinical examinations and ECG were selected as controls. Demographic characteristics and background risk factors were obtained using a questionnaire by expert nurses. Venous blood sample was obtained from participants for measuring the anti Chlamydia IgG and IgM antibodies using ELISA method. The prevalence of antibodies was compared in both groups and its relation with coronary syndrome was evaluated.    RESULTS: 88 and 49 patients were enrolled in case and control groups, respectively. Mean age of patients and the controls was 14 ± 59.7 and 13 ± 56.9 years, respectively (P = 0.26. Anti Chlamydia IgG seropositivity rate was 63(71.9% and 23(46.9% in case and controlcontrol groups, respectively (P < 0.01; OR: 2.85; CI 95%: 1.38 - 5.9. Anti Chlamydia IgM was positive in 1 patient and 1 control. Anti Chlamydia IgG seropositivity rate was higher in patients older than 50 years old than those younger than 50 years old (OR: 2.83; CI 95%: 1.31 -1.14. There was a significant relation between BMI, smoking and Anti Chlamydia IgG seropositivity.    CONCLUSION: Considering the relation between anti Chlamydia antibody IgG seropositivity with BMI and myocardial infarction, it seems that appropriate diagnosis and treatment of these prone patients can be benefical.

    Full Text Available The purpose of this research was to compare group-based and internet-based physical activity interventions in terms of desirability, participant characteristics, exercise self-efficacy, and barrier self-efficacy. Pretest questionnaires were completed prior to voluntary enrollment into either of the ten-week physical activity interventions. Both interventions were based on Social Cognitive Theory and the Transtheoretical Model. Interventions were followed with posttest questionnaires. Results demonstrated that the internet intervention attracted more participants, but only the group-based participants showed significant increases in exercise and barrier self-efficacy. At pretest, participants who selected the internet intervention were significantly lower in life and job satisfaction than those who selected the group intervention. Results suggest that traditional group-based exercise interventions are helpful for improving cognitions associated with exercise behavior change (e.g., exercise self-efficacy and that the internet intervention may help employees who fall into an "unhappy employee" typology

    Although there are a number of highly efficacious in-person treatments designed to ameliorate relationship distress, only a small proportion of distressed couples seek out in-person treatment. Recently developed internet-based interventions based on these in-person treatments are a promising way to circumvent common barriers to in-person treatment and give more distressed couples access to these efficacious interventions. The overarching aims of this review are to provide couple and family therapists with a broad overview of the available internet-based interventions and provide suggestions about how these interventions might be utilized before, during, or after in-person treatment. First, we review internet-based interventions targeting individual psychopathology (e.g. anxiety and depression). These interventions would be particularly useful as an adjunctive resource for in-person couple or family therapy when referrals for a concurrent in-person individual therapist are not feasible (because of time, financial, or geographic constraints). The majority of the review centers on internet-based interventions for distressed couples and covers four distinct types of resources: relationship advice websites, assessment/feedback interventions, enrichment interventions for satisfied couples, and interventions targeting at-risk or distressed couples. We close with a case study of one couple's journey through a newly developed intervention targeting at-risk couples, OurRelationship.com, and provide two appendices with information on currently available internet-based interventions.

    Internet data is introduced into public health arena under the features of fast updating and tremendous volume. Mining and analyzing internet data, researchers can model the internet-based surveillance system to assess the distribution of health-related events. There are two main types of internet-based surveillance systems, i.e. active and passive, which are distinguished by the sources of information. Through passive surveillance system, information is collected from search engine and social media while the active system gathers information through provision of the volunteers. Except for serving as a real-time and convenient complementary approach to traditional disease, food safety and adverse drug reaction surveillance program, Internet-based surveillance system can also play a role in health-related behavior surveillance and policy evaluation. Although several techniques have been applied to filter information, the accuracy of internet-based surveillance system is still bothered by the false positive information. In this article, we have summarized the development and application of internet-based surveillance system in public health to provide reference for a better surveillance program in China.

  19. Association between recruitment methods and attrition in Internet-based studies.

    Directory of Open Access Journals (Sweden)

    Paolo Bajardi

    Full Text Available Internet-based systems for epidemiological studies have advantages over traditional approaches as they can potentially recruit and monitor a wider range of individuals in a relatively inexpensive fashion. We studied the association between communication strategies used for recruitment (offline, online, face-to-face and follow-up participation in nine Internet-based cohorts: the Influenzanet network of platforms for influenza surveillance which includes seven cohorts in seven different European countries, the Italian birth cohort Ninfea and the New Zealand birth cohort ELF. Follow-up participation varied from 43% to 89% depending on the cohort. Although there were heterogeneities among studies, participants who became aware of the study through an online communication campaign compared with those through traditional offline media seemed to have a lower follow-up participation in 8 out of 9 cohorts. There were no clear differences in participation between participants enrolled face-to-face and those enrolled through other offline strategies. An Internet-based campaign for Internet-based epidemiological studies seems to be less effective than an offline one in enrolling volunteers who keep participating in follow-up questionnaires. This suggests that even for Internet-based epidemiological studies an offline enrollment campaign would be helpful in order to achieve a higher participation proportion and limit the cohort attrition.

    2017-01-01

    Full Text Available Free Talk is recognized as an effective approach to teaching college English in China to improve students’ English speaking. With the popularity of Internet around the world, the Internet-based Free Talk demonstrates more advantages in motivating students to engage in English learning. In this paper, the author compares the main features of the Internet-based Free Talk with the five components of the MUSIC Model of Motivation synthesized from current research and theory in the field of motivation. Furthermore, the author illustrates how Internet facilitates Free Talk through online writing service system and online QQ community. The comparison reveals that the success of the Internet-based Free Talk is consistent with the key motivation principles. This paper indicates that professors and researchers in higher education could design and evaluate their instruction according to the components of the MUSIC model of motivation.

  3. Utility and potential of rapid epidemic intelligence from internet-based sources.

    2017-10-01

    Rapid epidemic detection is an important objective of surveillance to enable timely intervention, but traditional validated surveillance data may not be available in the required timeframe for acute epidemic control. Increasing volumes of data on the Internet have prompted interest in methods that could use unstructured sources to enhance traditional disease surveillance and gain rapid epidemic intelligence. We aimed to summarise Internet-based methods that use freely-accessible, unstructured data for epidemic surveillance and explore their timeliness and accuracy outcomes. Steps outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist were used to guide a systematic review of research related to the use of informal or unstructured data by Internet-based intelligence methods for surveillance. We identified 84 articles published between 2006-2016 relating to Internet-based public health surveillance methods. Studies used search queries, social media posts and approaches derived from existing Internet-based systems for early epidemic alerts and real-time monitoring. Most studies noted improved timeliness compared to official reporting, such as in the 2014 Ebola epidemic where epidemic alerts were generated first from ProMED-mail. Internet-based methods showed variable correlation strength with official datasets, with some methods showing reasonable accuracy. The proliferation of publicly available information on the Internet provided a new avenue for epidemic intelligence. Methodologies have been developed to collect Internet data and some systems are already used to enhance the timeliness of traditional surveillance systems. To improve the utility of Internet-based systems, the key attributes of timeliness and data accuracy should be included in future evaluations of surveillance systems. Copyright © 2017 The Authors.

  4. A Comparison of Internet-Based Participant Recruitment Methods: Engaging the Hidden Population of Cannabis Users in Research

    Directory of Open Access Journals (Sweden)

    Elizabeth Clare Temple

    2011-01-01

    Full Text Available While a growing number of researchers are embracing Internet-based data collection methods, the adoption of Internet-based recruitment methods has been relatively slow. This may be because little is known regarding the relative strengths and weaknesses of different methods of Internet-based participant recruitment, nor how these different recruitment strategies impact on the data collected. These issues are addressed in this article with reference to a study comparing the effectiveness of three Internet-based strategies in recruiting cannabis users for an online study. Consideration of the recruitment data leads us to recommend that researchers use multipronged Internet-based recruitment campaigns with appropriately detailed recruitment messages tailored to the population of interest and located carefully to ensure they reach the intended audience. Further, we suggest that building rapport directly with potential participants, or utilising derived rapport and implicit endorsements, is an important aspect of successful Internet-based participant recruitment strategies.

    Internet-based mental health services increase rapidly. However, national surveys are incomplete and the consequences for such services are poorly discussed. This study describes characteristics of 60 Internet-based mental health services in Norway and Sweden and discusses their social consequences. More than half of the services were offered by voluntary organisations and targeted towards young people. Professionals answered service users' questions in 60% of the services. Eight major themes were identified. These characteristics may indicate a shift in the delivery of mental health services in both countries, and imply changes in the understanding of mental health.

    Urbano, L.

    2005-12-01

    We have developed and tested an internet based application that facilitates the creation of animations for use in lectures and permits movie production by students in laboratory classes. Animation have been found to be extremely useful educational aids in the geosciences, particularly relating to topics requiring comprehension of geospatial relationships. With this program, instructors are able to assemble and caption animations using an online video clip catalogue and present these movies through a standard internet browser. Captioning increases student comprehension by increasing the multimodality of information delivery. For student use, we developed an exercise for introductory, undergraduate, laboratory class sections that was informed by learning pedagogy, particularly as related to game-based learning. Students were asked to assemble video clips and captions into a coherent movie to explain geospatial concepts, with questions such as "Explain why we have seasons?" The affinity of students to digital technology, particularly computer games and digital media, makes this type of exercise particularly captivating to the typical undergraduate. The opportunity to select and arrange video clips (and add background music) into a unique production offers students a greater degree of ownership of the learning process and allows unique non-linear pathways for accomplishing learning objectives. Use in a laboratory section permitted rapid feedback from the instructor. The application was created using open-sourced software and the database populated with video clips and music contributed by faculty and students under a non-commercial-use license. This tool has the potential to permit the wider dissemination of scientific research results given the increasing use animations for scientific visualization, because it eases the creation of multiple presentations targeted to various audiences and allows user participation in the creation of multimedia.

    Full Text Available Background: The prevalence of anxiety disorders among children and adolescents are found to be approximately between 8–12 and 5–10, respectively, and the long-lasting effects of such disorders can expose the sufferers to impairment and dysfunction in several areas of life the examples of which are poor educational performance, low self-esteem, and depression. The present study aims to evaluate the efficacy of internet-based, cognitive-behavioral therapy (ICBT in treating the anxiety disorders among adolescent females. Materials and Methods: The sample included thirty girls aged between 10 and 18 years suffering from a variety of anxiety disorders, under pharmaceutical therapy and referred to clinics of child and adolescent psychiatry specialists in Isfahan. The sample was selected through diagnostic interviews by psychiatrists based on the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision; afterward, they were randomly assigned to either the experimental or the control groups. To evaluate the efficacy of an ICBT in reducing anxiety disorder symptoms, Screen for Child Anxiety Related Emotional Disorders questionnaire was administered among the patients both before and 4 weeks after the treatment. Results: The covariance analysis results aimed to compare the anxiety disorder score variations between the two groups which demonstrate the fact that anxiety disorder scores in these two groups differ from one another (P < 0.001. Conclusions: This study is comprised of two Conclusions.the significant reduction in the mean of anxiety disorders scores in the experimental group compared to those in control group can be indicative of the efficacy of ICBT. In addition the significant reduction in the average of anxiety disorders symptoms' scores according to the type of anxiety disorders in the experimental group, compared to those in control group, can be indicative of the efficacy of ICBT.

    This review considers the roles of Chlamydia spp. and newly identified Chlamydia-like organisms in miscarriage, stillbirths and preterm labour in both animals and humans. The cause of miscarriage, stillbirth and preterm labour often remains unexplained. Intracellular bacteria that grow either poorly or not at all on media used routinely to detect human pathogens could be the aetiological agents of these obstetrical conditions. There is growing evidence that Chlamydia trachomatis, Chlamydophila abortus, Chlamydophila psittaci and Chlamydophila pneumoniae infections may result in adverse pregnancy outcomes in humans and/or animals. Waddlia, a Chlamydia-like organism first isolated from an aborted bovine, has emerged as an agent of abortion in cattle. Recently, Waddlia was also implicated in human foetal death. Moreover, Parachlamydia acanthamoebae is also abortigenic in ruminants. Whether additional novel Chlamydia-like organisms, such as Protochlamydia amoebophila, Neochlamydia hartmanellae, Criblamydia sequanensis, Rhabdochlamydia crassificans and Simkania negevensis, are involved in foetal loss or premature delivery remains to be determined. This review provides an update on the consequences of chlamydial infection during pregnancy and summarizes current evidence suggesting that some Chlamydia-related organisms are probably emerging obstetrical pathogens.

    Full Text Available Background. Focus upon depression and prevention of its occurrence among adolescents is increasing. Novel ways of dealing with this serious problem have become available especially by means of internet-based prevention and treatment programs of depression and anxiety. The use of Internet-based intervention programs among adolescents has revealed some difficulties in implementation that need to be further elucidated. The aim of this study is to investigate the association between personality and adolescent depression and the characteristics of users of an Internet-based intervention program. Method. The Junior Temperament and Character Inventory (JTCI, the General Self-Efficacy scale (GSE and the Centre for Epidemiological Studies-Depression scale (CES-D have been administered to a sample (=1234 of Norwegian senior high-school students. Results. Multiple regression analysis revealed associations between depression and gender, and several JTCI domains and facets. In line with previous findings in adults, high Harm Avoidance and low Self-Directedness emerged as the strongest predictors of adolescent depressive symptoms. Further, in logistic regression analysis with the covariates JTCI, GSE and CES-D, the only significant variables predicting use/non-use were the CES-D and the temperament domain Reward Dependence. Conclusion. The results in this study revealed level of depressive symptoms as the strongest predictor of the use of the Internet based intervention and that personality might provide useful information about the users.

    2004-01-01

    The objective was to review the effect of Internet-based continuing medical education (CME) interventions on physician performance and health care outcomes. Data sources included searches of MEDLINE (1966 to January 2004), CINAHL (1982 to December 2003), ACP Journal Club (1991 to July/August 2003), and the Cochrane Database of Systematic Reviews (third quarter, 2003). Studies were included in the analyses if they were randomized controlled trials of Internet-based education in which participants were practicing health care professionals or health professionals in training. CME interventions were categorized according to the nature of the intervention, sample size, and other information about educational content and format. Sixteen studies met the eligibility criteria. Six studies generated positive changes in participant knowledge over traditional formats; only three studies showed a positive change in practices. The remainder of the studies showed no difference in knowledge levels between Internet-based interventions and traditional formats for CME. The results demonstrate that Internet-based CME programs are just as effective in imparting knowledge as traditional formats of CME. Little is known as to whether these positive changes in knowledge are translated into changes in practice. Subjective reports of change in physician behavior should be confirmed through chart review or other objective measures. Additional studies need to be performed to assess how long these new learned behaviors could be sustained. eLearning will continue to evolve as new innovations and more interactive modes are incorporated into learning.

    Health risk assessments are becoming more popular as a tool to conveniently and effectively reach community-dwelling adults who may be at risk for serious chronic conditions such as coronary heart disease (CHD). The use of such instruments to improve adults' risk factor awareness and concordance with clinically measured risk factor values could be an opportunity to advance public health knowledge and build effective interventions. The objective of this study was to determine if an Internet-based health risk assessment can highlight important aspects of agreement between respondents' self-reported and clinically measured CHD risk factors for community-dwelling adults who may be at risk for CHD. Data from an Internet-based cardiovascular health risk assessment (Heart Aware) administered to community-dwelling adults at 127 clinical sites were analyzed. Respondents were recruited through individual hospital marketing campaigns, such as media advertising and print media, found throughout inpatient and outpatient facilities. CHD risk factors from the Framingham Heart Study were examined. Weighted kappa statistics were calculated to measure interrater agreement between respondents' self-reported and clinically measured CHD risk factors. Weighted kappa statistics were then calculated for each sample by strata of overall 10-year CHD risk. Three samples were drawn based on strategies for treating missing data: a listwise deleted sample, a pairwise deleted sample, and a multiple imputation (MI) sample. The MI sample (n=16,879) was most appropriate for addressing missing data. No CHD risk factor had better than marginal interrater agreement (κ>.60). High-density lipoprotein cholesterol (HDL-C) exhibited suboptimal interrater agreement that deteriorated (eg, κInternet-based health risk assessments such as Heart Aware may contribute to public health surveillance, but they must address selection bias of Internet-based recruitment methods.

    There are numerous barriers that limit access to evidence-based treatment for posttraumatic stress disorder (PTSD). Internet-based guided self-help is a treatment option that may help widen access to effective intervention, but the approach has not been sufficiently explored for the treatment of PTSD. Forty two adults with DSM-5 PTSD of mild to moderate severity were randomly allocated to internet-based self-help with up to 3 h of therapist assistance, or to a delayed treatment control group. The internet-based program included eight modules that focused on psychoeducation, grounding, relaxation, behavioural activation, real-life and imaginal exposure, cognitive therapy, and relapse prevention. The primary outcome measure was reduction in clinician-rated traumatic stress symptoms using the clinician administered PTSD scale for DSM-V (CAPS-5). Secondary outcomes were self-reported PTSD symptoms, depression, anxiety, alcohol use, perceived social support, and functional impairment. Posttreatment, the internet-based guided self-help group had significantly lower clinician assessed PTSD symptoms than the delayed treatment control group (between-group effect size Cohen's d = 1.86). The difference was maintained at 1-month follow-up and dissipated once both groups had received treatment. Similar patterns of difference between the two groups were found for depression, anxiety, and functional impairment. The average contact with treating clinicians was 2½ h. Internet-based trauma-focused guided self-help for PTSD is a promising treatment option that requires far less therapist time than current first line face-to-face psychological therapy. © 2017 Wiley Periodicals, Inc.

    The Internet is increasingly being applied in health education worldwide; however there is little knowledge of its use in Chinese higher education institutions. The present study provides the first review and highlights the deficiencies and required future advances in Chinese Internet-based health education. Two authors independently conducted a duplicate Internet search in order to identify information regarding Internet-based health education in China. The findings showed that Internet-based education began in China in September 1998. Currently, only 16 of 150 (10.7%) health education institutions in China offer fee-based online undergraduate degree courses, awarding associates and/or bachelors degrees. Fifteen of the 16 institutions were located in the middle or on the eastern coast of China, where were more developed than other regions. Nursing was the most popular discipline in Internet-based health education, while some other disciplines, such as preventive medicine, were only offered at one university. Besides degree education, Chinese institutions also offered non-degree online training and free resources. The content was mainly presented in the form of PowerPoint slides or videos for self-learning. Very little online interactive mentoring was offered with any of the courses. There is considerable potential for the further development of Internet-based health education in China. These developments should include a focus on strengthening cooperation among higher education institutions in order to develop balanced online health curricula, and on enhancing distance education in low- and middle-income regions to meet extensive learning demands.

  19. PREFERENCES ON INTERNET BASED LEARNING ENVIRONMENTS IN STUDENT-CENTERED EDUCATION

    Full Text Available Nowadays, educational systems are being questionned to find effective solutions to problems that are being encountered, and discussions are centered around the ways of restructuring systems so as to overcome difficulties. As the consequences of the traditional teaching approach, we can indicate that the taught material is not long-lasting but easily forgotten, that students do not sufficiently acquire the knowledge and skills that are aimed at developing, and that students lack transferring their knowledge to real life. In our current situation, individuals prefer to use educational resources where and when they want, based on their individual skills and abilities. Throughout the world, because the internet infrastructure has developed quite rapidly, it has been offered as an alternative way for a rich learning and teaching environment. This study aims at determining teacher candidates’ preferences regarding internet-based learning environments in student-centered education by involving the teacher candidates enrolled at Osmangazi University, Faculty of Education, Primary School Teaching, Mathematics Teaching and Computer and Educational Technologies Education programmes. This study is a descriptive study. The data collection scale consists of the “Constructivist Internet-based Education of Science Scale (CILES-S”. The sample group of teacher candidates in the study showed differences with respect to their preferences regarding internet-based learning in student-centered education. The candidates scored higher in the internet-based learning environments of Cognitive Development and Critical Judgement. The lowest average scores of the sample group were observed in the internet-based learning environment of Episthemologic awareness.

  20. [Chlamydia pneumoniae--etiology of ophthalmia neonatorum].

    The authors observed mucous discharge in palpebral aperture, accompanied by a different degree of effusion of eyelids and chemosis of conjunctivae, particularly the tarsal ones, in 12 physiological newborns. Chlamydia pneumoniae proved to be the etiological agent in the newborn ophthalmia. The eye infection was not detected in the same period of time and in the same maternity hospital in the period of observation from September 1999 to March 2001. The detection of Chlamydia pneumoniae was performed in conjunctiva smears. The impression films on slides were examined by the method of indirect immunofluorescence with the use of specific monoclonal antibodies (medac, Germany). In the early stages the secretion included a sanguineous component, which was then changing into a mucoid or mucopurulent form. The character of conjunctival symptoms was changing in the course of inflammation. Effusion of the lower transitory fold (plica) was gradually accompanied by a picture of pseudofollicular changes on the tarsal conjunctiva. Clarithromycin in the form of syrup at daily doses of 15 mg/kg/day for the period of two weeks offered an efficient therapy of the affection. Control smears after 14 days were always negative and, at the same time, the pathological finding on the conjunctivae disappeared. The nasolacrimal obstruction was the only complication of this chlamydia infection, taking place in seven sucklings, i.e. in 58%. The passage through lacrimal drainage system reappeared in all the affected infants until they reached one year of age. The remaining question to be answered is the way the newborns encountered the infection. A nosocomial infection may be the case, but Chlamydia pneumoniae could also be present in the urogenital tract of mothers and transferred to the newborn via the birth canal similarly as is the case of Chlamydia trachomatis infection. The mode of infection deserves further investigation.

    Chlamydia comprises a group of obligate intracellular bacterial parasites responsible for a variety of diseases in humans and animals, including several zoonoses. Chlamydia trachomatis causes diseases such as trachoma, urogenital infection and lymphogranuloma venereum with severe morbidity. Chlamydia pneumoniae is a common cause of community-acquired respiratory tract infections. Chlamydia psittaci, causing zoonotic pneumonia in humans, is usually hosted by birds, while Chlamydia abortus, causing abortion and fetal death in mammals, including humans, is mainly hosted by goats and sheep. We used multi-locus sequence typing to asses the population structure of Chlamydia. In total, 132 Chlamydia isolates were analyzed, including 60 C. trachomatis, 18 C. pneumoniae, 16 C. abortus, 34 C. psittaci and one of each of C. pecorum, C. caviae, C. muridarum and C. felis. Cluster analyses utilizing the Neighbour-Joining algorithm with the maximum composite likelihood model of concatenated sequences of 7 housekeeping fragments showed that C. psittaci 84/2334 isolated from a parrot grouped together with the C. abortus isolates from goats and sheep. Cluster analyses of the individual alleles showed that in all instances C. psittaci 84/2334 formed one group with C. abortus. Moving 84/2334 from the C. psittaci group to the C. abortus group resulted in a significant increase in the number of fixed differences and elimination of the number of shared mutations between C. psittaci and C. abortus. C. psittaci M56 from a muskrat branched separately from the main group of C. psittaci isolates. C. psittaci genotypes appeared to be associated with host species. The phylogenetic tree of C. psittaci did not follow that of its host bird species, suggesting host species jumps. In conclusion, we report for the first time an association between C. psittaci genotypes with host species.

    Synthesis of protein by the obligate intracellular parasitic bacteria Chlamydia psittaci (6BC) and Chlamydia trachomatis (serovar L2) isolated from host cells (host-free chlamydiae) was demonstrated for the first time. Incorporation of [ 35 S]methionine and [ 35 S]cysteine into trichloroacetic acid-precipitable material by reticulate bodies of chlamydiae persisted for 2 h and was dependent upon a exogenous source of ATP, an ATP-regenerating system, and potassium or sodium ions. Magnesium ions and amino acids stimulated synthesis; chloramphenicol, rifampin, oligomycin, and carbonyl cyanide p-trifluoromethoxyphenylhydrazone (a proton ionophore) inhibited incorporation. Ribonucleoside triphosphates (other than ATP) had little stimulatory effect. The optimum pH for host-free synthesis was between 7.0 and 7.5. The molecular weights of proteins synthesized by host-free reticulate bodies closely resembled the molecular weights of proteins synthesized by reticulate bodies in an intracellular environment, and included outer membrane proteins. Elementary bodies of chlamydiae were unable to synthesize protein even when incubated in the presence of 10 mM dithiothreitol, a reducing agent which converted the highly disulfide bond cross-linked major outer membrane protein to monomeric form

    The capacity to advertise via the Internet continues to contribute to the shifting dynamics in adult commercial sex work. eHealth interventions have shown promise to promote Internet-based sex workers' health and safety internationally, yet minimal attention has been paid in Canada to developing such interventions. Understanding the information communicated in Internet-based sex work advertisements is a critical step in knowledge development to inform such interventions. The purpose of this content analysis was to increase our understanding of the health and safety information within the Internet advertisements among women, men, and transgender sex workers and to describe how this information may be utilized to inform eHealth service development for this population. A total of 75 Internet-based sex worker advertisements (45 women, 24 men, and 6 transgender persons) were purposefully selected from 226 advertisements collected as part of a larger study in Western Canada. Content analysis was employed to guide data extraction about demographic characteristics, sexual services provided, service restrictions, health practices and concerns, safety and security, and business practices. Frequencies for each variable were calculated and further classified by gender. Thematic analysis was then undertaken to situate the communications within the social and commercialized contexts of the sex industry. Four communications themes were identified: (1) demographic characteristics; (2) sexual services; (3) health; and (4) safety and security.

    The objective of the study was to identify experiences and attitudes of German and Norwegian general practitioners (GPs) towards Internet-based remote consultation solutions supporting communication between GPs and patients in the context of the German and Norwegian healthcare systems. Interviews with four German and five Norwegian GPs were conducted. The results were qualitatively analyzed. All interviewed GPs stated they would like to make use of Internet-based remote consultations in the future. Current experiences with remote consultations are existent to a limited degree. No GP reported to use a comprehensive remote consultation solution. The main features GPs would like to see in a remote consultation solution include asynchronous exchange of text messages, video conferencing with text chat, scheduling of remote consultation appointments, secure login and data transfer and the integration of the remote consultation solution into the GP's EHR system.

  13. Going Multi-viral: Synthedemic Modelling of Internet-based Spreading Phenomena

    Full Text Available Epidemics of a biological and technological nature pervade modern life. For centuries, scientific research focused on biological epidemics, with simple compartmental epidemiological models emerging as the dominant explanatory paradigm. Yet there has been limited translation of this effort to explain internet-based spreading phenomena. Indeed, single-epidemic models are inadequate to explain the multimodal nature of complex phenomena. In this paper we propose a novel paradigm for modelling internet-based spreading phenomena based on the composition of multiple compartmental epidemiological models. Our approach is inspired by Fourier analysis, but rather than trigonometric wave forms, our components are compartmental epidemiological models. We show results on simulated multiple epidemic data, swine flu data and BitTorrent downloads of a popular music artist. Our technique can characterise these multimodal data sets utilising a parsimonous number of subepidemic models.

    The in vitro activity of six synthetic peptides against 36 strains of Chlamydia from different origins was investigated. Clavanin MO (CMO) proved to be the most active peptide, reducing the inclusion number of all Chlamydia strains from eight different species tested by ≥50% at 10 µg mL -1 . Mastoparan L showed an equal activity against C. trachomatis, C. pneumoniae, C. suis, and C. muridarum, but did not exert any inhibitory effect against C. psittaci, C. pecorum, C. abortus, and C. avium even at 80 µg mL -1 . These data suggest that CMO could be a promising compound in the prevention and treatment of chlamydial infections. © 2017 Wiley Periodicals, Inc.

    Full Text Available This is the case of encephalitis associated with chlamydia infection of central nervous system. The diagnostic protocol of the patient included: a careful observation of somatic and neurological status, laboratory tests of blood and cerebrospinal fluid, neurovisualization. The results of the diagnostic protocol suggest that laboratory tests blood and cerebrospinal fluid possess low sensitivity and specificity. The MRI study has revealed the localization and inflammatory character of the changes in brain tissue; it has also helped to choose the most favorable area for the stereotaxic biopsy. The obtained tissue was evaluated by means of light (immunohistochemistry and electronic microscopy. The active chlamydia infection was estimated. The subsequent antibacterial etiotropic therapy resulted in the regression of the neurologic symptoms and remission.The intravitalpathomorphology study of the brain could be recommended for the management of the severe encephalitis of the unknown origin.

    Full Text Available Background: Chlamydia psittaci is an intracellular bacterium primarily causing respiratory diseases in birds but may also be transmitted to other animals, including humans. The prevalence of the pathogen in wild birds in Sweden is largely unknown. Methods: DNA was extracted from cloacae swabs and screened for C. psittaci by using a 23S rRNA gene PCR assay. Partial 16S rRNA and ompA gene fragments were sequence determined and phylogenies were analysed by the neighbour-joining method. Results and conclusion: The C. psittaci prevalence was 1.3% in 319 Peregrine Falcons and White-tailed Sea Eagles, vulnerable top-predators in Sweden. 16S rRNA and ompA gene analysis showed that novel Chlamydia species, as well as novel C. psittaci strains, are to be found among wild birds.

    A 27 kDa Chlamydia trachomatis Mip-like protein with homology of a 175-amino-acid C-terminal fragment to the surface-exposed Legionella pneumophila mip-gene product has previously been described. In this paper the entire chlamydia Mip-like sequence of C. trachomatis serovar L2 (lymphogranuloma...... venereum (LGV) biovar) is presented. The sequence shows high similarity to the legionella Mip protein and its C-terminal region, like that of the legionella Mip, has high amino acid similarity to eukaryotic and prokaryotic FK506-binding proteins. The chlamydial mip-like gene was detected by polymerase...... chain reaction (PCR) in other C. trachomatis serovars and by sequencing of the mip-like genes of serovars B and E (trachoma biovar) was shown to be highly conserved within the two major biovars of C. trachomatis. Monoclonal and polyclonal antibodies raised against the recombinant Mip-like protein failed...

    Recruiting participants to randomized controlled trials of health interventions can be very difficult. Internet-based recruitment is becoming an increasingly important mode of recruitment, yet there are few detailed accounts of experiences recruiting participants to mental health interventions. To report on our experience with Internet-based recruitment to an online depression prevention intervention and pass on lessons we learned. Participants were recruited to the Mood Memos study, an online preventive depression intervention, purely through Internet-based sources. The study was targeted to adults with subthreshold depression symptoms from several English-speaking countries. A variety of online recruitment sources were trialed, including search engine advertising (Google, Yahoo!, Bing), Facebook advertising, posts in forums and online noticeboards, and promotion through relevant websites and email newsletters of mental health organizations. The study website received visits from 94,808 individuals over the 14-month recruitment period. The recruitment target was reached with 1699 individuals signing up to the randomized controlled trial and 1326 fully enrolling. Most visitors arrived via Google advertising, which promoted a depression-screening questionnaire. Google advertising accounted for nearly half of the total participants who signed up to the study, at an average cost of AUD $12 per participant. Promoting the study through trustworthy organizations and websites known to participants was also effective. Recruitment techniques that were less effective were contacting forums, email groups, and community noticeboards. Several techniques, including Google advertising, were successful in recruiting participants to a trial evaluating an online depression intervention. Results suggest that Internet-based recruitment to mental health interventions is feasible and can be relatively affordable. ACTRN12609000925246.

    Noise-induced hearing loss is a significant occupational injury for firefighters exposed to intermittent noise on the job. It is important to educate firefighters about using hearing protection devices whenever they are exposed to loud noise. Computer technology is a relatively new health education approach and can be useful for tailoring specific aspects of behavioral change training. The purpose of this study is to present the development process of an Internet-based tailored intervention program and to assess its efficacy. The intervention programs were implemented for 372 firefighters (mean age = 44 years, Caucasian = 82%, male = 95%) in three states (California, Illinois, and Indiana). The efficacy was assessed from firefighters' feedback through an Internet-based survey. A multimedia Internet-based training program was developed through (a) determining program content and writing scripts, (b) developing decision-making algorithms for tailoring, (c) graphic design and audio and video productions, (d) creating computer software and a database, and (e) postproduction quality control and pilot testing. Participant feedback regarding the training has been very positive. Participants reported that they liked completing the training via computer (83%) and also that the Internet-based training program was well organized (97%), easy to use (97%), and effective (98%) and held their interest (79%). Almost all (95%) would recommend this Internet training program to other firefighters. Interactive multimedia computer technology using the Internet was a feasible mode of delivery for a hearing protection intervention among firefighters. Participants' favorable feedback strongly supports the continued utilization of this approach for designing and developing interventions to promote healthy behaviors.

    Purpose The incidence of sexually transmitted infections (STIs) and human immunodeficiency virus (HIV) is high among young Chilean women, and there are no STI or HIV prevention interventions available to them that incorporate technology. The purpose of this study was to investigate the preliminary efficacy of an Internet-based STI and HIV prevention intervention (I-STIPI) for Chilean young women on measures of STI- and HIV-related information, motivation, behavioral skills, and preventive behaviors. Design This is a pretest-posttest study. Forty young Chilean women between 18 and 24 years of age participated in an investigation of the I-STIPI’s preliminary efficacy on STI and HIV prevention-related outcomes between baseline and a postintervention assessment. The intervention consisted of four online modules. Data collection was conducted in Santiago, Chile. Paired-samples t test analysis was used to determine whether there were significant differences in each of the outcome variables. Findings After receiving I-STIPI, women reported a significant increase in levels of STI- and HIV-related knowledge, attitudes toward the use of condoms and perceived self-efficacy, and a reduction of risky sexual behaviors with uncommitted partners. Conclusions The I-STIPI showed promise as an Internet-based intervention that can reduce barriers to accessing preventive interventions and increase STI and HIV preventive behaviors in young Chilean women. Clinical Relevance The study provided important information about the ability of an Internet-based intervention to reduce young women’s risk factors and to provide positive preliminary efficacy on STI- and HIV-related outcomes. Internet-based interventions can eliminate many barriers to receiving prevention interventions and may prove to be cost effective. PMID:25410132

    Chlamydia infections in women cause pelvic inflammatory disease, which often results in devastating consequences of infertility, ectopic pregnancy, or chronic pelvic pain. The infection is largely asymptomatic. To determine the seroprevalence of Chlamydia trachomatis in Enugu, South Eastern Nigeria. A population-based prospective study comprising female residents of Enugu, South Eastern Nigeria. Indirect solid phase enzyme immunoassay of Chlamydia antibodies was done using ImmunoComb C0. Trachomatis IgG Kit (Orgenics). The population comprised 136 female undergraduate students and 150 non-student women. The overall prevalence of C. trachomatis in the population studied was 29.4%. The percentage of subjects who admitted to be having multiple sexual partners was higher among the student population (71.2%) compared to those from the non-student population (28.8%). The highest percentage of seroprevalence was 28 (33.3%) in the age group of 20-24 years for the student population and 18 (21.4%) in the age group of 25-29 years for the non-student population. The highest seroprevalence of C. trachomatis antibodies (69.0%) in both populations was observed in females without any history of infection. Females that had pelvic inflammatory disease, sexually transmitted infection, and secondary infertility assayed for C. trachomatis had seroprevalence levels of 19%, 9.5%, and 2.4%, respectively. There was a positive correlation between positive Chlamydia assay and the type of subject population (student or non-student) with r2 value of 1.55 at P Nigeria.

    Technological advancements allow new approaches to psychotherapy via electronic media. The eating disorder literature currently contains no studies on internet intervention in anorexia nervosa (AN). This study presents a RCT on an internet-based relapse prevention program (RP) over nine months after inpatient treatment for AN. The sample comprised 258 women, randomized to the RP or treatment as usual (TAU). Expert- and self-ratings were evaluated by intent-to-treat analyses. Concerning age, age at onset and comorbidity, both groups were comparable at randomization. During the RP, the intervention group gained weight while the TAU group had minimal weight loss. RP completers gained significantly more body weight than patients in the TAU condition. Group-by-time comparisons for eating-related cognitions and behaviors and general psychopathology showed a significantly more favorable course in the RP program for "sexual anxieties" and "bulimic symptoms" (interview), and "maturity fears" and "social insecurity" (EDI-2). General psychopathology showed no significant group-by-time interaction. Important factors for successful relapse prevention were adherence to the intervention protocol and increased spontaneity. Considering the unfavorable course and chronicity of anorexia nervosa (AN), internet-based relapse prevention in AN following inpatient treatment appears a promising approach. Future internet-based programs may be further improved and enhanced. Copyright © 2012 Elsevier Ltd. All rights reserved.

    To investigate the effect of Internet-based training (IBT), with and without supervision, on therapists' (N = 61) cognitive-behavioral therapy (CBT) skills in routine clinical practice. Participants were randomized into 3 conditions: (1) Internet-based training with use of a consultation worksheet (IBT-CW); (2) Internet-based training with CBT supervision via Skype (IBT-S); and (3) "delayed-training" controls (DTs), who did not receive the training until all data collection was completed. The IBT participants received access to training over a period of 3 months. CBT skills were evaluated at pre-, mid- and posttraining/wait using assessor competence ratings of recorded therapy sessions. Hierarchical linear analysis revealed that the IBT-S participants had significantly greater CBT competence at posttraining than did IBT-CW and DT participants at both the mid- and posttraining/wait assessment points. There were no significant differences between IBT-CW and the delayed (no)-training DTs. IBT programs that include supervision may be a scalable and effective method of disseminating CBT into routine clinical practice, particularly for populations without ready access to more-traditional "live" methods of training. There was no evidence for a significant effect of IBT without supervision over a nontraining control, suggesting that merely providing access to IBT programs may not be an effective method of disseminating CBT to routine clinical practice.

    Full Text Available Finance faculty are increasingly encouraged to use internet-based technologies in teaching. This paper examines students’ perceptions of finance faculty who use internet-based technologies and the impact on their learning experiences in undergraduate introductory corporate finance, investments, and MBA investments courses. The results suggest that offering all course materials online may enhance students’ learning experiences, however, the technologies may be best thought of as teaching tools. A better methodology for a finance course delivery may be that of in-classroom interactions between an instructor and the students while all the pertinent course materials are available online throughout the semester. There is a statistically significant difference between MBA (Master of Business Administration students and undergraduate business students in terms of their desire to use the internet for learning finance. Consistent with previous research, results indicate that it may not be common practice among faculty to use internet-based technologies, and that assistant professors tend to use technologies in teaching more often than their higher-ranked colleagues do.

    Physical inactivity is a modifiable risk factor for breast cancer. Physical activity interventions that can be delivered through the Internet have the potential to increase participant reach. The efficacy of an Internet-based physical activity intervention was tested in a sample of women at an elevated risk for breast cancer. A total of 55 women with at least 1 first-degree relative with breast cancer (but no personal history of breast cancer) were randomized to a 3-month theoretically grounded Internet-based physical activity intervention or an active control arm. Minutes of moderate to vigorous physical activity, psychosocial mediators of physical activity adoption and maintenance, as well as worry and perceived risk of developing breast cancer were assessed at baseline, 3-month, and 5-month follow up. Participants were on average 46.2 (SD = 11.4) years old with a body mass index of 27.3 (SD = 4.8) kg/m2. The intervention arm significantly increased minutes of moderate to vigorous physical activity compared to the active control arm at 3 months (213 vs. 129 min/week) and 5 months (208 vs. 119 min/week; both ps Internet-based physical activity intervention may substantially increase physical activity in women with a family history of breast cancer.

    Social network analysis (SNA) is based on a conceptual network representation of social interactions and is an invaluable tool for conservation professionals to increase collaboration, improve information flow, and increase efficiency. We present two approaches to constructing internet-based social networks, and use an existing traditional (survey-based) case study to illustrate in a familiar context the deviations in methods and results. Internet-based approaches to SNA offer a means to overcome institutional hurdles to conducting survey-based SNA, provide unique insight into an institution's web presences, allow for easy snowballing (iterative process that incorporates new nodes in the network), and afford monitoring of social networks through time. The internet-based approaches differ in link definition: hyperlink is based on links on a website that redirect to a different website and relatedness links are based on a Google's "relatedness" operator that identifies pages "similar" to a URL. All networks were initiated with the same start nodes [members of a conservation alliance for the Calumet region around Chicago ( n = 130)], but the resulting networks vary drastically from one another. Interpretation of the resulting networks is highly contingent upon how the links were defined.

    Adjustment disorder is one of the most diagnosed mental disorders. However, there is a lack of studies of specialized internet-based psychosocial interventions for adjustment disorder. We aimed to analyze the outcomes of an internet-based unguided self-help psychosocial intervention BADI for adjustment disorder in a two armed randomized controlled trial with a waiting list control group. In total 284 adult participants were randomized in this study. We measured adjustment disorder as a primary outcome, and psychological well-being as a secondary outcome at pre-intervention (T1) and one month after the intervention (T2). We found medium effect size of the intervention for the completer sample on adjustment disorder symptoms. Intervention was effective for those participants who used it at least one time in 30-day period. Our results revealed the potential of unguided internet-based self-help intervention for adjustment disorder. However, high dropout rates in the study limits the generalization of the outcomes of the intervention only to completers.

    Self-control resources can be defined in terms of "energy." Repeated attempts to override desires and impulses can result in a state of reduced self-control energy termed "ego depletion" leading to a reduced capacity to regulate future self-control behaviors effectively. Regular practice or "training" on self-control tasks may improve an individual's capacity to overcome ego depletion effectively. The current research tested the effectiveness of training using a novel Internet-based smartphone application to improve self-control and reduce ego depletion. In two experiments, participants were randomly assigned to either an experimental group, which received a daily program of self-control training using a modified Stroop-task Internet-based application delivered via smartphone to participants over a 4-week period, or a no-training control group. Participants assigned to the experimental group performed significantly better on post-training laboratory self-control tasks relative to participants in the control group. Findings support the hypothesized training effect on self-control and highlight the effectiveness of a novel Internet-based application delivered by smartphone as a practical means to administer and monitor a self-control training program. The smartphone training application has considerable advantages over other means to train self-control adopted in previous studies in that it has increased ecological validity and enables effective monitoring of compliance with the training program.

    Chlamydia is the most common notifiable sexually transmissible infection in Australia. Left untreated, it can develop into pelvic inflammatory disease and infertility. The majority of notifications come from general practice and it is ideally situated to test young Australians. The Australian Chlamydia Control Effectiveness Pilot (ACCEPt) was a multifaceted intervention that aimed to reduce chlamydia prevalence by increasing testing in 16- to 29-year-olds attending general practice. GPs were interviewed to describe the effectiveness of the ACCEPt intervention in integrating chlamydia testing into routine practice using Normalization Process Theory (NPT). GPs were purposively selected based on age, gender, geographic location and size of practice at baseline and midpoint. Interview data were analysed regarding the intervention components and results were interpreted using NPT. A total of 44 GPs at baseline and 24 at midpoint were interviewed. Most GPs reported offering a test based on age at midpoint versus offering a test based on symptoms or patient request at baseline. Quarterly feedback was the most significant ACCEPt component for facilitating a chlamydia test. The ACCEPt intervention has been able to moderately normalize chlamydia testing among GPs, although the components had varying levels of effectiveness. NPT can demonstrate the effective implementation of an intervention in general practice and has been valuable in understanding which components are essential and which components can be improved upon.

    Ensuring rapid access to high quality sexual health services is a key public health objective, both in the United Kingdom and internationally. Internet-based testing services for sexually transmitted infections (STIs) are considered to be a promising way to achieve this goal. This study will evaluate a nascent online STI testing and results service in South East London, delivered alongside standard face-to-face STI testing services. The aim of this study is to establish whether an online testing and results services can (1) increase diagnoses of STIs and (2) increase uptake of STI testing, when delivered alongside standard face-to-face STI testing services. This is a single-blind randomized controlled trial. We will recruit 3000 participants who meet the following eligibility criteria: 16-30 years of age, resident in the London boroughs of Lambeth and Southwark, having at least one sexual partner in the last 12 months, having access to the Internet and willing to take an STI test. People unable to provide informed consent and unable to read and understand English (the websites will be in English) will be excluded. Baseline data will be collected at enrolment. This includes participant contact details, demographic data (date of birth, gender, ethnicity, and sexual orientation), and sexual health behaviors (last STI test, service used at last STI test and number of sexual partners in the last 12 months). Once enrolled, participants will be randomly allocated either (1) to an online STI testing and results service (Sexual Health 24) offering postal self-administered STI kits for chlamydia, gonorrhoea, syphilis, and HIV; results via text message (short message service, SMS), except positive results for HIV, which will be delivered by phone; and direct referrals to local clinics for treatment or (2) to a conventional sexual health information website with signposting to local clinic-based sexual health services. Participants will be free to use any other interventions

    Full Text Available Abstract Background Depression is a highly prevalent condition, affecting more than 15% of the adult population at least once in their lives. Guided self-help is effective in the treatment of depression. The purpose of this study is to investigate the effectiveness of two Internet-based guided self-help treatments with adults reporting elevated depressive symptoms. Other research questions concern the identification of potential mediators and the search for subgroups who respond differently to the interventions. Methods This study is a randomized controlled trial with three conditions: two treatment conditions and one waiting list control group. The two treatment conditions are Internet-based cognitive behavior therapy and Internet-based problem-solving therapy. They consist of 8 and 5 weekly lessons respectively. Both interventions are combined with support by e-mail. Participants in the waiting list control group receive the intervention three months later. The study population consists of adults from the general population. They are recruited through advertisements in local and national newspapers and through banners on the Internet. Subjects with symptoms of depression (≥ 16 on the Center for Epidemiological Studies Depression scale are included. Other inclusion criteria are having sufficient knowledge of the Dutch language, access to the Internet and an e-mail address. Primary outcome is depressive symptoms. Secondary outcomes are anxiety, quality of life, dysfunctional cognitions, worrying, problem solving skills, mastery, absence at work and use of healthcare. We will examine the following variables as potential mediators: dysfunctional cognitions, problem solving skills, worrying, anxiety and mastery. Potential moderating variables are: socio-demographic characteristics and symptom severity. Data are collected at baseline and at 5 weeks, 8 weeks, 12 weeks and 9 months after baseline. Analyses will be conducted on the intention

    Background: The impact of Chlamydia trachomatis (chlamydia) control on the incidence of pelvic inflammatory disease (PID) is theoretically limited by the proportion of PID caused by chlamydia. We estimate the population excess fraction (PEF) of treated chlamydia infection on PID at 12-months...... in settings with widespread chlamydia control (testing and treatment) and compare this to the estimated PEF of untreated chlamydia. Methods: We used two large retrospective population-based cohorts of women of reproductive age from settings with widespread chlamydia control to calculate the PEF of treated...... chlamydia on PID at 12-months. We undertook a systematic review to identify further studies that reported the risk of PID in women who were tested for chlamydia (infected and uninfected). We used the same method to calculate the PEF in eligible studies then compared all estimates of PEF. Results...

    The advances in molecular biology of the last decades have dramatically improved the field of diagnostic bacteriology. In particular, PCR-based technologies have impacted the diagnosis of infections caused by obligate intracellular bacteria such as pathogens from the Chlamydiacae family. Here, we describe a real-time PCR-based method using the Taqman technology for the diagnosis of Chlamydia pneumoniae, Chlamydia psittaci, and Chlamydia abortus infection. The method presented here can be applied to various clinical samples and can be adapted on opened molecular diagnostic platforms.

    Rose, Susan; Dhandayudham, Arun

    2014-06-01

    Compulsive and addictive forms of consumption and buying behaviour have been researched in both business and medical literature. Shopping enabled via the Internet now introduces new features to the shopping experience that translate to positive benefits for the shopper. Evidence now suggests that this new shopping experience may lead to problematic online shopping behaviour. This paper provides a theoretical review of the literature relevant to online shopping addiction (OSA). Based on this selective review, a conceptual model of OSA is presented. The selective review of the literature draws on searches within databases relevant to both clinical and consumer behaviour literature including EBSCO, ABI Pro-Quest, Web of Science - Social Citations Index, Medline, PsycINFO and Pubmed. The article reviews current thinking on problematic, and specifically addictive, behaviour in relation to online shopping. The review of the literature enables the extension of existing knowledge into the Internet-context. A conceptual model of OSA is developed with theoretical support provided for the inclusion of 7 predictor variables: low self-esteem, low self-regulation; negative emotional state; enjoyment; female gender; social anonymity and cognitive overload. The construct of OSA is defined and six component criteria of OSA are proposed based on established technological addiction criteria. Current Internet-based shopping experiences may trigger problematic behaviours which can be classified on a spectrum which at the extreme end incorporates OSA. The development of a conceptual model provides a basis for the future measurement and testing of proposed predictor variables and the outcome variable OSA.

    Genital Chlamydia Trachomatis infection is one of the most common sexually transmitted infections with more than 50 million new cases occurred globally every year. Underdiagnosed and untreated, it can generate long term severe complications including PID, infertility, ectopic pregnancy and chronic pelvic pain. Among 20 patients diagnosed with PID and infertility in our medical office during one year, we selected a study group of 10 patients with genital Chlamydia Trachomatis infection. The diagnostic methods used were anamnesis, clinical examination, Pap smear, bacteriological and serological tests, ultra sound examination. The group of patients selected was monitored for one year. The treatment took into account general measures for both partners and specific measures (antibiotic treatment and focused laser therapy). The initial group was split in two, group A treated only with antibiotics and group B treated with both antibiotics and laser therapy. All the 5 patients of group B presented an improvement of the clinical manifestations and 3 of them ended up with pregnancy. On the other hand, in group B, only one patient manifested total disappearance of pains and the infertility persisted for all. It is noteworthy that the association of laser therapy in the treatment of Chlamydia Trachomatis infection has brought significant improvement in the inflammatory processes of internal genitalia (PID) and in the fertility of the couple.

    Background The increases in STI rates since the late 1990s in Canada have occurred despite widespread primary care and targeted public health programs and in the setting of universal health care. More innovative interventions are required that would eliminate barriers to STI testing such as internet-based or mail-in home and community service testing for patients that are hard to reach, who refuse to go for clinician-based testing, or who decline an examination. Jurisdictions such as New Zealand and some American states currently use self-collected sampling, but without the required evidence to determine whether self-collected specimens are as accurate as clinician-collected specimens in terms of chlamydia and gonorrhea diagnostic accuracy. The objective of the review is to compare self-collected vaginal, urine, pharyngeal and rectal samples to our reference standard - clinician-collected cervical, urethral, pharyngeal and rectal sampling techniques to identify a positive specimen using nucleic acid amplification test assays. Methods The hierarchical summary receiver operating characteristic and the fixed effect models were used to assess the accuracy of comparable specimens that were collected by patients compared to clinicians. Sensitivity and specificity estimates with 95% confidence intervals (CI) were reported as our main outcome measures. Findings We included 21 studies based on over 6100 paired samples. Fourteen included studies examined chlamydia only, 6 compared both gonorrhea and chlamydia separately in the same study, and one examined gonorrhea. The six chlamydia studies comparing self-collection by vaginal swab to a clinician-collected cervical swab had the highest sensitivity (92%, 95% CI 87-95) and specificity (98%, 95% CI 97-99), compared to other specimen-types (urine/urethra or urine/cervix). Six studies compared urine self-samples to urethra clinician-collected samples in males and produced a sensitivity of 88% (95% CI 83-93) and a specificity of

  8. Twenty years of Internet-based research at SCiP: A discussion of surviving concepts and new methodologies.

    Wolfe, Christopher R

    2017-10-01

    This discussion of the symposium 20 Years of Internet-Based Research at SCiP: Surviving Concepts, New Methodologies compares the issues faced by the pioneering Internet-based psychology researchers who presented at the first symposia on the topic, at the 1996 annual meeting of the Society for Computers in Psychology, to the issues facing researchers today. New methodologies unavailable in the early days of Web-based psychological research are discussed, with an emphasis on mobile computing with smartphones that is capitalizing on capabilities such as touch screens and gyro sensors. A persistent issue spanning the decades has been the challenge of conducting scientific research with consumer-grade electronics. In the 1996 symposia on Internet-based research, four advantages were identified: easy access to a geographically unlimited subject population, including subjects from very specific and previously inaccessible target populations; bringing the experiment to the subject; high statistical power through large sample size; and reduced cost. In retrospect, it appears that Internet-based research has largely lived up to this early promise-with the possible exception of sample size, since the public demand for controlled psychology experiments has not always been greater than the supply offered by researchers. There are many reasons for optimism about the future of Internet-based research. However, unless courses and textbooks on psychological research methods begin to give Web-based research the attention it deserves, the future of Internet-based psychological research will remain in doubt.

    This study aimed to estimate the population-attributable risks (PARs) of 9 major risk factors for stroke in Korea through a case-control study and to test the feasibility and validity of internet-based control recruitment. From April 2008 to September 2009, controls were enrolled via internet after providing consent for participation through a web-based survey. The cases included patients who were admitted to the participating centers due to acute stroke or transient ischemic attack within 7 days of onset during the study period. Each control was age- and sex-matched with 2 cases. Adjusted odd ratios, age-standardized prevalence, and PARs were estimated for the 9 major risk factors using the prevalence of risk factors in the control group and the age and sex characteristics from Korea's national census data. In total, 1041 controls were matched to 2082 stroke cases. Because of a shortage of elderly controls in the internet-based recruitment, 248 controls were recruited off-line. The PARs were 23.44%, 10.95%, 51.32%, and 6.35% for hypertension, diabetes, smoking, and stroke history, respectively. Hypercholesterolemia, atrial fibrillation, obesity, coronary heart disease, and a family history of stroke were not associated with stroke. Comparison with education and religion of the control group with that mentioned in the national census data showed a notable difference. The study results imply that internet-based control recruitment for a case-control study requires careful selection of risk factors with high self-awareness and effective strategies to facilitate the recruitment of elderly participants.

    Parent training programs promote positive parenting and benefit low-income children, but are rarely used. Internet-based delivery may help expand the reach of parent training programs, although feasibility among low-income populations is still unclear. We examined the feasibility of internet-based parent training, in terms of internet access/use and engagement, through two studies. In Study 1, 160 parents recruited from Women, Infants, and Children (WIC) centers completed a brief paper survey regarding internet access and use (all parents received government aid). We found high levels of access, openness, and comfort with the internet and internet-enabled devices. In Study 2, a pilot study, we assessed use of an online parenting program in a project with a sample of 89 predominately low-income parents (75% received government aid). Parents learned about a new, online parenting program (the "5-a-Day Parenting Program") and provided ratings of level of interest and program use 2-weeks and 4-weeks later. Local website traffic was also monitored. At baseline, parents were very interested in using the web-based program, and the majority of parents (69.6%) reported visiting the website at least once. However, in-depth use was rare (only 9% of parents reported frequent use of the online program). Results support the feasibility of internet-based parent training for low-income parents, as most parent were able to use the program and were interested in doing so. However, results also suggest the need to develop strategies to promote in-depth program use.

    Advances in Internet technology now enable unprecedented global collaboration and collective knowledge exchange. Up to this time, there have been limited efforts to use these technologies to actively promote knowledge exchange across the global pediatric critical care community. To develop an open-access, peer-reviewed, not-for-profit Internet-based learning application, OPENPediatrics, a collaborative effort with the World Federation of Pediatric Intensive and Critical Care Societies, was designed to promote postgraduate educational knowledge exchange for physicians, nurses, and others caring for critically ill children worldwide. Description of program development. International multicenter tertiary pediatric critical care units across six continents. Multidisciplinary pediatric critical care providers. A software application, providing information on demand, curricular pathways, and videoconferencing, downloaded to a local computer. In 2010, a survey assessing postgraduate educational needs was distributed through World Federation of Pediatric Intensive and Critical Care Societies to constituent societies. Four hundred and twenty-nine critical care providers from 49 countries responded to the single e-mail survey request. Respondents included 68% physicians and 28% nurses who care for critically ill children. Fifty-two percent of respondents reported accessing the Internet at least weekly to obtain professional educational information. The five highest requests were for educational content on respiratory care [mechanical ventilation] (48% [38%]), sepsis (28%), neurology (25%), cardiology (14%), extracorporeal membrane oxygenation (10%), and ethics (8%). Based on these findings, and in collaboration with researchers in adult learning and online courseware, an application was developed and is currently being used by 770 registered users in 60 countries. We describe here the development and implementation of an Internet-based application which is among the first

    Explore employees' perceptions of ability to follow the Mediterranean diet (MedDiet), preferences for setting goals if asked to follow the MedDiet, and expectations of an Internet-based, workplace MedDiet intervention. Seven focus groups to guide intervention development. Four workplaces (business/professional services, government branches) in Southwest England. Employees (n = 29, 51.7% women), ages 24-58 years. Ability to follow the MedDiet; preferences for goal-setting if asked to follow the MedDiet; intervention content. Data were analyzed with the use of thematic analysis. Participants perceived that adhering to some MedDiet recommendations would be challenging and highlighted cost, taste, and cooking skills as adherence barriers. Behavior change preferences included a tailored approach to goal-setting, reviewing goal progress via a website/smartphone app, and receiving expert feedback via an app/website/text/face-to-face session. Desirable features of an Internet-based MedDiet application included recipes, interactivity, nutritional information, shopping tips, cost-saving information, and a companion smartphone app. Engaging in social support was deemed important to facilitate adherence. An Internet-based, workplace MedDiet intervention should address adherence barriers, utilize a tailored approach to setting and reviewing goals, and activate social support to facilitate adherence. These findings provide insights to planning to promote the MedDiet in non-Mediterranean regions. Copyright © 2016 Society for Nutrition Education and Behavior. Published by Elsevier Inc.

    While there have been several reviews exploring the outcomes of various eHealth studies, none have been gastroenterology-specific. This paper aims to evaluate the research conducted within gastroenterology which utilizes internet-based eHealth technology to promote physical and psychological well-being. A systematic literature review of internet-based eHealth interventions involving gastroenterological cohorts was conducted. Searched databases included: EbSCOhost Medline, CINAHL, and PsycINFO. Inclusion criteria were studies reporting on eHealth interventions (both to manage mental health problems and somatic symptoms) in gastroenterology, with no time restrictions. Exclusion criteria were non-experimental studies, or studies using only email as primary eHealth method, and studies in language other than English. A total of 17 papers were identified; seven studies evaluated the efficacy of a psychologically oriented intervention (additional two provided follow-up analyses exploring the original published data) and eight studies evaluated disease management programs for patients with either irritable bowel syndrome, inflammatory bowel disease (IBD) or celiac disease. Overall, psychological eHealth interventions were associated with significant reductions in bowel symptoms and improvement in quality of life (QoL) that tended to continue up to 12 months follow up. The eHealth disease management was shown to generally improve QoL, adherence, knowledge about the disease, and reduce healthcare costs in IBD, although the studies were associated with various methodological problems, and thus, this observation should be confirmed in well-designed interventional studies. Based on the evidence to date, eHealth internet-based technology is a promising tool that can be utilized to both promote and enhance gastrointestinal disease management and mental health.

    We evaluate the value of an internet-based educational animated video designed to prepare children for MRI scans, and whether this video reduces scan-related anxiety in children with a neurological disorder, and healthy controls. Participants completed a pre- and post-scan questionnaire evaluating participant online viewing behaviour, understanding of the MRI procedure, anxiety regarding the MRI, impact of animation in preparing the child and whether the child's expectation of the MRI scan matched their experience. 21 children were recruited (12 healthy controls) ranging in age from 6.5 to 11.5 years. The animation was successfully accessed by participants on a range of digital devices and had high levels of approval. Children who viewed the animation had a good understanding of the MRI procedure and low anxiety levels prior to the scan, and reported that their expectations broadly matched the real-life MRI experience. Children reported that the animation positively impacted on their preparation with similar ratings before and after the scan, and the impact on preparation was rated greater by younger children. There were no group differences between healthy children and those with the neurological disorder for ratings of anxiety, impact on preparation and expectation of the experience. This evaluation demonstrates accessibility, acceptability and relevance of internet-based educational animation for typically developing children, and children with a neurodisability aged 6 to 11 years, with positive impact on preparation for MRI. Advances in knowledge: The internet-based educational animation provides a widely accessible tool to support preparation of children for non-sedated MRI.

    The effectiveness and practicality of the "Luftikids" (www.luftikids.de) structured, internet-based asthma refresher course was evaluated in a pilot study with 53 patients (ages 8 - 14 years). All patients had previously participated in either an inpatient or outpatient asthma education program. This prospective study examined the effect of a 4-week refresher course on parameters such as asthma symptoms (coughing, dyspnea), the number of unscheduled doctor's visits, use of on-demand medications, number of days absent from school, and asthma monitoring using the Asthma Control Questionnaire (ACQ) and lung function tests. The duration of program use and the number of logins was used to investigate acceptance of the game format. Data were collected at the beginning of the study and at 4 - 6 months after the end of the online refresher course. Significant changes were shown with regard to the decrease in intensity of asthma symptoms such as coughing (p = 0.001) and dyspnea (p = 0.007), reduction in the number of unscheduled doctor's visits (p = 0.005), the use of on-demand medications (4.0 ± 6.5 vs. 1.5 ± 4.9, p = children and adolescents derived "much" to "very much" benefit. Only 7.5% reported no effect. Participation in the "Luftikids" internet-based asthma refresher course resulted in fewer asthma symptoms, a decrease in unscheduled doctor's visits, reduction in the use of on-demand medications, decrease in the number of days absent from school, and improved asthma knowledge. No effect in lung function could be demonstrated. The results support the effectiveness and good acceptance of an outpatient, internet-based asthma refresher course. Young asthma patients in particular can succeed with and be motivated by this form of refresher course. © Georg Thieme Verlag KG Stuttgart · New York.

    Introduction: Knowledge regarding the importance of sleep in health and performance and good sleep hygiene practices is low, especially among adolescents and young adults. It is important to improve sleep literacy. Introductory psychology is one of the most highly enrolled courses at colleges and universities. This study tested the impact of an Internet-based learning module on improving sleep literacy in this venue. Methods: An Internet-based supplementary learning module containing sleep physiology and hygiene information was developed using content from the Harvard Medical School sleep educational website http://www.understandingsleep.org. Access to the module was provided as an extra credit activity for 2 of 4 sections (Supplemental Sleep, SS, N = 889) of an introductory college psychology course during their standard instruction on sleep and dreaming. The remaining 2 sections (Standard Instruction, SI, N = 878) only were encouraged to visit the website without further direction. Level of knowledge was assessed before and after availability to the module/website and at the end of the semester. Students were asked to complete a survey at the end of the semester inquiring whether they made any changes in their sleep behaviors. Results: Two hundred fifty students participated in the extra credit activity and had data available at all testing points. Students in the SS Group had a significant improvement in sleep knowledge test scores after interacting with the website in comparison to the SI group (19.41 ± 3.15 vs. 17.94 ± 3.08, p sleep habits after participation in the extra credit sleep activity (p sleep learning module has the potential to enhance sleep literacy and change behavior among students enrolled in an introductory college psychology course.

    To establish the long-term efficacy of a universal internet-based alcohol and cannabis prevention programme in schools. A cluster-randomized controlled trial was conducted to assess the effectiveness of the Climate Schools: Alcohol and Cannabis Course. The evidence-based course, aimed at reducing alcohol and cannabis use, is facilitated by the internet and consists of 12 novel and curriculum consistent lessons delivered over 6 months. A total of 764 year 8 students (13 years) from 10 Australian secondary schools were allocated randomly to the internet-based prevention programme (n = 397, five schools), or to their usual health classes (n = 367, five schools). Participants were assessed at baseline, immediately post, and 6 and 12 months following completion of the intervention, on measures of alcohol and cannabis knowledge, attitudes, use and related harms. This paper reports the final results of the intervention trial, 12 months following the completion of the Climate Schools: Alcohol and Cannabis Course. The effectiveness of the course 6 months following the intervention has been reported previously. At the 12-month follow-up, compared to the control group, students in the intervention group showed significant improvements in alcohol and cannabis knowledge, a reduction in average weekly alcohol consumption and a reduction in frequency of drinking to excess. No differences between groups were found on alcohol expectancies, cannabis attitudes or alcohol- and cannabis-related harms. The course was found to be acceptable by teachers and students as a means of delivering drug education in schools. Internet-based prevention programs for school-age children can improve student's knowledge about alcohol and cannabis, and may also reduce alcohol use twelve months after completion.

    Inefficient transfer of personal health records among providers negatively impacts quality of health care and increases cost. This multicenter study evaluates the implementation of the first Internet-based image-sharing system that gives patients ownership and control of their imaging exams, including assessment of patient satisfaction. Patients receiving any medical imaging exams in four academic centers were eligible to have images uploaded into an online, Internet-based personal health record. Satisfaction surveys were provided during recruitment with questions on ease of use, privacy and security, and timeliness of access to images. Responses were rated on a five-point scale and compared using logistic regression and McNemar's test. A total of 2562 patients enrolled from July 2012 to August 2013. The median number of imaging exams uploaded per patient was 5. Most commonly, exams were plain X-rays (34.7%), computed tomography (25.7%), and magnetic resonance imaging (16.1%). Of 502 (19.6%) patient surveys returned, 448 indicated the method of image sharing (Internet, compact discs [CDs], both, other). Nearly all patients (96.5%) responded favorably to having direct access to images, and 78% reported viewing their medical images independently. There was no difference between Internet and CD users in satisfaction with privacy and security and timeliness of access to medical images. A greater percentage of Internet users compared to CD users reported access without difficulty (88.3% vs. 77.5%, P Internet-based image-sharing system is feasible and surpasses the use of CDs with respect to accessibility of imaging exams while generating similar satisfaction with respect to privacy.

    Researchers studying physical activity often face challenges dealing with recruitment and resources, particularly when conducting longitudinal Internet-based research. Commonly raised methodological problems such as minority recruitment, participant commitment, and participant-staff involvement are addressed through a theoretically driven recruitment and adherence protocol in The Women's Exercise Injuries: Incidence and Risk Factors (WIN) Internet-based study. The objectives of this paper were to review and suggest solutions to problems of: (1) low recruitment of diverse samples, (2) low adherence, and (3) staffing needs. We recruited 1303 community-dwelling women and followed them through a multiple-phase, longitudinal, Internet-based study. Recruitment and adherence data were analyzed through descriptive methods and logistic regressions to examine participant adherence and sociodemographic factors and predictors of who entered the long-term phase of the study. We successfully retained 71.6% of the sample through 4 recruitment phases. Twenty-seven percent of the initially recruited sample was racial/ethnically diverse, 24% began the long-term phase, and 23% completed. Several strategies to enhance participant commitment were successfully used during the practice phase, providing a successful, low staff to participant ratio. Logistic regression indicated being married, being older, and having greater Internet skills were predictive of successfully entering the long-term phase of the study. Recruitment and compliance protocols were successful in meeting overall and racial/ethnic enrollment and recruitment goals. The theoretically based practice phase techniques were successful in re-engaging noncompliant participants. Strategies for minority enrollment and compliance are evaluated.

    We developed a novel Internet-based blended learning programme that allows busy health care professionals to attain core competency in clinical research. This study details the educational strategies and learning outcomes of the programme. This study was conducted at Kyoto University and seven satellite campuses from September 2009 to March 2010. A total of 176 health care professionals who had never attempted to attain core competency in clinical research were enrolled. The participants were supplied with a novel programme comprising the following four strategies: online live lectures at seven satellite campuses, short examinations after each lecture, an Internet-based feedback system and an end-of-course examination. We assessed the proportion of attendance at the lectures as the main outcome. In addition, we evaluated interaction via the feedback system and scores for end-of-course examination. Of the 176 participants, 134 (76%) reported working more than 40 hours per week. The mean proportion of attendance over all 23 lectures was 82%. A total of 156 (89%) participants attended more than 60% of all lectures and were eligible for the end-of-course examination. A total of the participants accessed the feedback system 3564 times and asked 284 questions. No statistically significant differences were noted in the end-of-course scores among medical doctors, pharmacists, registered nurses and other occupations. We developed an Internet-based blended learning programme providing core competency in clinical research. Most busy health care professionals completed the programme successfully. In addition, the participants could attain the core competency effectively, regardless of their occupation. © 2011 Blackwell Publishing Ltd.

    that are in agreement with the primary annotation. Forty two genes from the primary annotation are not predicted by EasyGene. The majority of these genes are listed as hypothetical in the primary annotation. The 15 novel predicted genes all overlap with genes on the complementary strand. We find homologues of several...... of the novel genes in C. trachomatis Serovar A and Chlamydia muridarum. Several of the genes have typical gene-like and protein-like features. Furthermore, we confirm transcriptional activity from 10 of the putative genes. The combined evidence suggests that at least seven of the 15 are protein coding genes...

    Internet-based testing programs are being increasingly used to reduce testing barriers for individuals at higher risk of infection, yet the population impact and potential for exacerbation of existing health inequities of these programs are not well understood. We used a large online sample of men who have sex with men (MSM) in Canada to measure acceptability of Internet-based testing and perceived advantages and disadvantages of this testing approach. We asked participants of the 2011/2012 Sex Now Survey (a serial online survey of gay and bisexual men in Canada) whether they intended to use Internet-based testing and their perceived benefits and disadvantages of use. We examined whether intention to use was associated with explanatory variables spanning (A) sociodemographics, (B) Internet and technology usage, (C) sexually transmitted infections (STI)/ human immunodeficiency virus (HIV) and risk, and (D) health care access and testing, using multivariable logistic regression (variable selection using Bayesian information criterion). Overall, intention to use was high (5678/7938, 71.53%) among participants with little variation by participant characteristics. In our final model, we retained the variables related to (B) Internet and technology usage: use of Internet to cruise for sex partners (adjusted odds ratio [AOR] 1.46, 95% CI 1.25-1.70), use of Internet to search for sexual health information (AOR 1.36, 95% CI 1.23-1.51), and mobile phone usage (AOR 1.19, 95% 1.13-1.24). We also retained the variables for (D) health care access and testing: not "out" to primary care provider (AOR 1.24, 95% CI 1.10-1.41), delayed/avoided testing due to privacy concerns (AOR 1.77, 95% CI 1.49-2.11), and delayed/avoided testing due to access issues (AOR 1.65, 95% CI 1.40-1.95). Finally, we retained the variable being HIV positive (AOR 0.56, 95% CI 0.46-0.68) or HIV status unknown (AOR 0.89, 95% CI 0.77-1.01), age Internet-based testing were privacy (2249/8388, 26.81%), general

  7. The Chlamydia type III secretion system C-ring engages a chaperone-effector protein complex.

    Full Text Available In Gram-negative bacterial pathogens, specialized chaperones bind to secreted effector proteins and maintain them in a partially unfolded form competent for translocation by type III secretion systems/injectisomes. How diverse sets of effector-chaperone complexes are recognized by injectisomes is unclear. Here we describe a new mechanism of effector-chaperone recognition by the Chlamydia injectisome, a unique and ancestral line of these evolutionarily conserved secretion systems. By yeast two-hybrid analysis we identified networks of Chlamydia-specific proteins that interacted with the basal structure of the injectisome, including two hubs of protein-protein interactions that linked known secreted effector proteins to CdsQ, the putative cytoplasmic C-ring component of the secretion apparatus. One of these protein-interaction hubs is defined by Ct260/Mcsc (Multiple cargo secretion chaperone. Mcsc binds to and stabilizes at least two secreted hydrophobic proteins, Cap1 and Ct618, that localize to the membrane of the pathogenic vacuole ("inclusion". The resulting complexes bind to CdsQ, suggesting that in Chlamydia, the C-ring of the injectisome mediates the recognition of a subset of inclusion membrane proteins in complex with their chaperone. The selective recognition of inclusion membrane proteins by chaperones may provide a mechanism to co-ordinate the translocation of subsets of inclusion membrane proteins at different stages in infection.

    There are numerous reports linking Chlamydia infection to human coronary atherosclerosis. However, there is a lack of data regarding this correlation in dogs and cats, and there are no reports investigating coronary arteriosclerosis and Chlamydia in these species. The aim of the present study was to examine whether there is a correlation between canine and feline spontaneous atherosclerosis or arteriosclerosis and the presence of Chlamydia. Archived histopathological samples of dogs (n = 16) and cats (n = 13) with findings of atherosclerosis or arteriosclerosis in heart tissue were examined for the presence of Chlamydiaceae using real-time PCR, ArrayTube Microarray and immunohistochemistry. Additionally, arteriosclerotic lesions of all cases were histologically classified and graded. Both canine atherosclerotic cases, and all 14 canine arteriosclerotic cases were negative for Chlamydia. Only one of the 13 arteriosclerotic feline cases was positive for Chlamydia by real-time PCR, revealing C. abortus by ArrayTube Microarray. To our knowledge, this is the first description of C. abortus in a cat. Overall, the type and grade of canine and feline arteriosclerotic lesions revealed similarities, and were predominantly moderate and hyperplastic. These findings suggest that there is no obvious correlation between canine and feline coronary arteriosclerosis and the presence of Chlamydia. In order to draw final conclusions about the correlation between Chlamydia and canine atherosclerosis, examination of more samples is required.

    A common measure to save energy in buildings is the adjustment of the operating time of the building service facilities to the busy time of the building (i.e. lowering period). For lack of better resources, the general lowering periods in irregularly occupied buildings often are reduced to a minimum or the adjustment of the operating time is completely missing. In order to adjust the operating time optimally to the actual busy time, an internet-based booking system has been developed, which allows users to register a room assignment online. This booking system is linked with the building service facilities. This ensure the optimal setting of the lowering periods and therefore allows saving energy. The technical implementation resulted from a programmable logic controller (PLC) that can be accessed via a web browser. Temperature offset boxes have been added as interface between the PLC and the existing facilities in order that the system is applicable in existing buildings too. The booking system has been installed in two test objects and has also been successfully tested with the responsible staff (caretaker, real estate management). The booking system may be contemplated online: http://www.hetag.ch. (author)

    Patients often have to sustain long waiting periods between the time they first apply for psychotherapy and the actual uptake of the treatment. To support patients who are on a wait-list for inpatient psychosomatic treatment an Internet-based preparatory treatment (VORSTAT) was developed. In a randomized controlled trial, VORSTAT proved to increase treatment motivation prior to intake and to accelerate the accommodation phase at the beginning of inpatient treatment. No impact of VORSTAT on inpatient treatment outcome was found. The aim of the present study was to investigate the effectiveness of VORSTAT after implementing the service into routine care. A large naturalistic observational study comparing VORSTAT participants (N=911) against non-participants (N=1721) was conducted. Propensity scores were used to control for potential confounding variables due to the non-randomized group allocation. Reliable improvement of self-reported impairment achieved during inpatient treatment was used as outcome measure. VORSTAT participants showed higher rates of reliable improvement in physical impairment (50.8% vs. 44.9%), psychological impairment (41.2% vs. 29.9%), and social problems (22.3% vs. 15.2%). An Internet-based preparation for psychotherapy is an effective approach to improve outcome of inpatient psychosomatic treatment. Copyright © 2015 Elsevier Inc. All rights reserved.

  14. Internet-Based Asthma Education -- A Novel Approach to Compliance: A case Report

    Cindy O'hara

    2006-01-01

    Full Text Available Asthma costs Canadians over $1.2 billion per annum and, despite advances, many asthmatic patients still have poor control. An action plan, symptom diary and measurement of peak expiratory flow have been shown to improve clinical outcomes. Effective educational interventions are an important component of good care. However, many rural sites lack not only access to education but physician care as well. It is reasonable, therefore, that an Internet-based asthma management program may be used as an approach. In the present case report, a novel approach that may increase access in these poorly serviced areas is presented. In an Internet-based asthma management program, patients are reviewed by a physician, receive education and are given a unique password that provides program access. Patients record symptoms and peak expiratory flow rates. The present case report shows that a patient can be assisted through an exacerbation, thus averting emergency intervention and stabilizing control, even when travelling on another continent.

    Full Text Available Background: Internet-based media coverage to explore the extent of awareness of a disease and perceived severity of an outbreak at a national level can be used for early outbreak detection. Dengue has emerged as a major public health problem in Sri Lanka since 2009. Objective: To compare Internet references to dengue in Sri Lana with references to other diseases (malaria and influenza in Sri Lanka and to compare Internet references to dengue in Sri Lanka with notified cases of dengue in Sri Lanka. Design: We examined Internet-based news media articles on dengue queried from HealthMap for Sri Lanka, for the period January 2007 to November 2015. For comparative purposes, we compared hits on dengue with hits on influenza and malaria. Results: There were 565 hits on dengue between 2007 and 2015, with a rapid rise in 2009 and followed by a rising trend ever since. These hits were highly correlated with the national epidemiological trend of dengue. The volume of digital media coverage of dengue was much higher than of influenza and malaria. Conclusions: Dengue in Sri Lanka is receiving increasing media attention. Our findings underpin previous claims that digital media reports reflect national epidemiological trends, both in annual trends and inter-annual seasonal variation, thus acting as proxy biosurveillance to provide early warning and situation awareness of emerging infectious diseases.

    Approximately 400,000 adolescents give birth in the USA annually. Although one-half experience depressive symptoms, less than 25% comply with referrals for depression evaluation and treatment. The current study tested the effectiveness of an Internet-based depression intervention on seeking depression treatment. Based upon the theory of planned behavior (TPB), the intervention included vignettes, questions and answers, and resources. Before the intervention, immediately after the intervention, and 2 weeks later the adolescent mothers (n = 151) answered questions related to TPB variables and depression treatment. Data were compared to adolescent mothers (n = 138) in the control group. Data were collected in community organizations or home visits for the control group. Adolescent mothers in the intervention group answered questions and completed the intervention from a computer of their choice. The adolescents were primarily African American (89.2%), less than high school educated (51.7%), had given birth in last year (97.1%), with a mean age 18.2 years. The intervention led to significant changes in attitude, perceived control, intention to seek mental health treatment, and actually seeking depression treatment. Untreated postpartum depression dramatically impacts a mother's relationship with her child, her functioning at work and school, health care-seeking behaviors, mothering skills, and her development as well as the development of her child. An Internet-based depression intervention is an inexpensive method to increase rates of depression treatment.

    The main objective of the current investigation was to assess the readability of Internet-based patient education materials related to the field of anesthesiology. We hypothesized that the majority of patient education materials would not be written according to current recommended readability grade level. Online patient education materials describing procedures, risks, and management of anesthesia-related topics were identified using the search engine Google (available at www.google.com) using the terms anesthesia, anesthesiology, anesthesia risks, and anesthesia care. Cross-sectional evaluation. None. Assessments of content readability were performed using validated instruments (Flesch-Kincaid Grade Formulae, the Gunning Frequency of Gobbledygook, the New Dale-Chall Test, the Fry graph, and the Flesch Reading Ease score). Ninety-six Web sites containing Internet patient education materials (IPEMs) were evaluated. The median (interquartile range) readability grade level for all evaluated IPEMs was 13.5 (12.0-14.6). All the evaluated documents were classified at a greater readability level than the current recommended readability grade, P Internet-based patient education materials related to the field of anesthesiology are currently written far above the recommended readability grade level. High complexity of written education materials likely limits access of information to millions of American patients. Redesign of online content of Web sites that provide patient education material regarding anesthesia could be an important step in improving access to information for patients with poor health literacy.

    Numerous professional societies, clinical practices, and hospitals provide Internet-based patient education materials (PEMs) to the general public, but not all of this information is written at a reading level appropriate for the average patient. The National Institutes of Health and the US Department of Health and Human Services recommend that PEMs be written at or below the sixth-grade level. Our purpose was to assess the readability of endoscopic sinus surgery (ESS)-related PEMs available on the Internet and compare readability levels of PEMs provided by three sources: professional societies, clinical practices, and hospitals. A descriptive and correlational design was used for this study. The readability of 31 ESS-related PEMs was assessed with four different readability indices: Flesch-Kincaid Grade Level (FKGL), Flesch Reading Ease Score (FRES), Simple Measure of Gobbledygook (SMOG), and Gunning Frequency of Gobbledygook (Gunning FOG). Averages were evaluated against national recommendations and between each source using analysis of variance and t tests. The majority of PEMs (96.8%) were written above the recommended sixth-grade reading level, based on FKGL (P Internet-based PEMs related to ESS, regardless of source type, were written well above the recommended sixth-grade level. Materials from the hospitals/university-affiliated websites had lower readability scores, but were still above recommended levels. Web-based PEMs pertaining to ESS should be written with the average patient in mind. Copyright © 2012 The American Laryngological, Rhinological, and Otological Society, Inc.

    Dropout from self-help cognitive-behavioral therapy for insomnia (CBT-I) potentially diminishes therapeutic effect and poses clinical concern. We analyzed the characteristics of subjects who did not complete a 6-week internet-based CBT-I program. Receiver operator characteristics (ROC) analysis was used to identify potential variables and cutoff for predicting dropout among 207 participants with self-report insomnia 3 or more nights per week for at least 3 months randomly assigned to self-help CBT-I with telephone support (n = 103) and self-help CBT-I (n = 104). Seventy-two participants (34.4%) did not complete all 6 sessions, while 42 of the 72 (56.9%) dropped out prior to the fourth session. Significant predictors of non-completion are total sleep time (TST) ≥ 6.82 h, Hospital Anxiety and Depression Scale depression score ≥ 9 and Insomnia Severity Index score dropout. Longer TST and less severe insomnia predict dropout in this study of self-help CBT-I, in contrast to shorter TST as a predictor in 2 studies of face-to-face CBT-I, while greater severity of depression predicts dropout in both this study and a study of face-to-face CBT-I. Strategies for minimizing dropout from internet-based CBT-I are discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Chlamydia is an obligate intracellular and gram negative coccobacilli and one of the most important causes of abortion in ruminants especially in ewes. This investigation was performed with the purpose of molecular study and sequencing of Chlamydia abortus isolated from aborted sheep fetuses of Alborz Province. In this study, DNA extraction was performed on 100 samples from aborted fetuses of 32 sheep flocks from different areas of Alborz province. Then using specific primers of gene IGS-Sr- RNA, polymerase chain reaction was conducted and 10 samples were selected randomly from the positive cases were sent to Macrogene company in Korea for sequencing. In this study, 37 samples from a total of 100 aborted fetuses were positive for Chlamydia abortus. After sequencing, more than 99 percent of the positive samples were similar with sequences in gene bank. The sequencing results indicated that the samples were very similar to isolates LN554882/1, AF051935/1 and CR848038/1 of the gene bank and were in the same cluster. Also, this investigation indicated that Chlamydia abortus is one of the main reasons of ewe abortion in Alborz province.

  1. The laboratory diagnosis of Chlamydia trachomatis infections

    Full Text Available Lower genital tract infections with Chlamydia trachomatis are predominantly asymptomatic in men and women. Diagnostic technology has provided several approaches to the diagnosis of C trachomatis. Outside of cells, Chlamydia can die or degrade without optimal storage and transportation. Because some of the other assays perform better on certain specimen types, it is important for laboratories to recognize these differences and provide advice to physicians and nurses collecting patient specimens, with the objective of diagnosing lower genital tract infections to prevent transmission and upper tract damage. Most invasive specimens, such as cervical or urethral swabs, may be collected for culture, antigen or nucleic acid detection. Noninvasive samples such as first-void urine and vaginal swabs can be easily collected by the patient; these samples must be tested by more sensitive nucleic acid amplification tests. These newer investigative strategies should enable implementation of screening programs to identify and treat partners. Serology has not been particularly useful for the diagnosis of acute C trachomatis infections in adults. Presently, it appears that antibiotic-resistant C trachomatis is not a clinical problem. Laboratories providing C trachomatis diagnosis require participation in continuous quality improvement programs.

    Internet-based applications are potentially useful and effective interventions to reach and support adolescents with mental health problems. Adolescents' commitment to the use of a new Internet-based intervention is closely related to the support they receive from healthcare professionals. This study describes nurses' experiences of the use of an Internet-based support system for adolescents with depressive disorders. Qualitative descriptive study design including individual interviews with nine nurses at two psychiatric outpatient clinics. The Technology Acceptance Model (TAM) was used as the theoretical background of the study. Nurses described several benefits of using the Internet-based support system in the care of adolescents with depressive disorders if the nurses integrate it into daily nursing practices. As perceived disadvantages the nurses thought that an adolescent's mental status might be a barrier to working with the support system. Perceived enablers could be organizational support, nurses' attitudes, and technology-related factors. Nurses' attitudes were identified as a barrier to supporting adolescents' use of the Internet-based support system. The findings suggest that the implementation plan and support from the organization, including that from nurse managers, are crucial in the process of implementing a technology-based support system.

    To report our experience with an Internet-based multicentre database that enables tumour documentation, as well as the collection of quality-related parameters and follow-up data, in surgically treated patients with prostate cancer. The system was used to assess the quality of prostate cancer surgery and to analyze possible time-dependent trends in the quality of care. An Internet-based database system enabled a standardized collection of treatment data and clinical findings from the participating urological centres for the years 2005-2009. An analysis was performed aiming to evaluate relevant patient characteristics (age, pathological tumour stage, preoperative International Index of Erectile Function-5 score), intra-operative parameters (operating time, percentage of nerve-sparing operations, complication rate, transfusion rate, number of resected lymph nodes) and postoperative parameters (hospitalization time, re-operation rate, catheter indwelling time). Mean values were calculated and compared for each annual cohort from 2005 to 2008. The overall survival rate was also calculated for a subgroup of the Berlin patients. A total of 914, 1120, 1434 and 1750 patients submitted to radical prostatectomy in 2005, 2006, 2007 and 2008 were documented in the database. The mean age at the time of surgery remained constant (66 years) during the study period. More than half the patients already had erectile dysfunction before surgery (median International Index of Erectile Function-5 score of 19-20). During the observation period, there was a decrease in the percentage of pT2 tumours (1% in 2005; 64% in 2008) and a slight increase in the percentage of patients with lymph node metastases (8% in 2005; 10% in 2008). No time trend was found for the operating time (142-155 min) or the percentage of nerve-sparing operations (72-78% in patients without erectile dysfunction). A decreasing frequency was observed for the parameters: blood transfusions (1.9% in 2005; 0.5% in 2008

  8. Towards an understanding of Internet-based problem shopping behaviour: The concept of online shopping addiction and its proposed predictors

    Science.gov (United States)

    ROSE, SUSAN; DHANDAYUDHAM, ARUN

    2014-01-01

    Background: Compulsive and addictive forms of consumption and buying behaviour have been researched in both business and medical literature. Shopping enabled via the Internet now introduces new features to the shopping experience that translate to positive benefits for the shopper. Evidence now suggests that this new shopping experience may lead to problematic online shopping behaviour. This paper provides a theoretical review of the literature relevant to online shopping addiction (OSA). Based on this selective review, a conceptual model of OSA is presented. Method: The selective review of the literature draws on searches within databases relevant to both clinical and consumer behaviour literature including EBSCO, ABI Pro-Quest, Web of Science – Social Citations Index, Medline, PsycINFO and Pubmed. The article reviews current thinking on problematic, and specifically addictive, behaviour in relation to online shopping. Results: The review of the literature enables the extension of existing knowledge into the Internet-context. A conceptual model of OSA is developed with theoretical support provided for the inclusion of 7 predictor variables: low self-esteem, low self-regulation; negative emotional state; enjoyment; female gender; social anonymity and cognitive overload. The construct of OSA is defined and six component criteria of OSA are proposed based on established technological addiction criteria. Conclusions: Current Internet-based shopping experiences may trigger problematic behaviours which can be classified on a spectrum which at the extreme end incorporates OSA. The development of a conceptual model provides a basis for the future measurement and testing of proposed predictor variables and the outcome variable OSA. PMID:25215218

    Full Text Available Relevance. Peripheral neuropathy (PNP in urogenital chlamydia reactive arthritis (CRA is described as single observations, and many clinical and pathogenetic aspects of this lesion of the nervous system remain unclear. Objective of the study: to evaluate the incidence and nature of the clinical course of PNP in CRA, the connection of the nerve and joint injuries, to explore the questions of pathogenetic constructions of this neuropathy, to identify risk factors. Material and methods. We observed 101 patients with CRA, mean age of them was 32 years, disease duration — 4 years, and the male to female ratio — 1 : 1. In 90 % of CRA cases, Chlamydia trochamatis was found in prostatic secretions, in scraps from the urethra, the cervix, the vaginal wall, in 83 % — positive serologic tests for chlamydia infection. Results. Signs of PNP in CRA were in 19 % of patients in the ratio of mononeuropathy to polyneuropathy as 1 : 1, with motor, sensory and mixed disorders in a ratio of 1 : 3 : 6, the presence of autonomic changes in every second patient and more frequent distal localization of the process in the hands, which is influenced by the severity of the articular syndrome, high levels of antichlamydia antibodies in the blood, and the axonal and demyelinating indicators of electroneuromyography — by the severity of urogenital lesions and the presence of Guillain-Barre syndrome. A high rate of arthritis progression is a prognosis-negative sign of PNP course in patients with CRA. The pathogenic constructions of PNP involve the inflammatory immune proteins, disturbances of vascular endothelial function and physicochemical surface rheological pro­perties of the serum. Conclusion. PNP takes place in every fifth patient with CRA, correlates with clinical and laboratory signs of joint disease, and in the future will be useful to identify actively this pathology of the nervous system for the subsequent timely rehabilitation, and CRA

    Chlamydia abortus is the most common known infectious cause of ovine abortion worldwide but is rarely linked with bovine abortion. The reasons for this differential pathogenesis are unknown but may involve differences in innate immune recognition and immune responsiveness. This is supported by the observation that chlamydial abortion in sheep is associated with an inflammatory cytokine/chemokine cascade that is not commonly observed in cattle.

    2017-03-01

    Full Text Available Bacteria of the phylum Chlamydiae infect a diverse range of eukaryotic host species, including vertebrate animals, invertebrates, and even protozoa. Characteristics shared by all Chlamydiae include their obligate intracellular lifestyle and a biphasic developmental cycle. The infectious form, the elementary body (EB, invades a host cell and differentiates into the replicative form, the reticulate body (RB, which proliferates within a membrane-bound compartment, the inclusion. After several rounds of division, RBs retro-differentiate into EBs that are then released to infect neighboring cells. The consequence of this obligatory transition between replicative and infectious forms inside cells is that Chlamydiae absolutely depend on the viability and functionality of their host cell throughout the entire infection cycle. We recently conducted a forward genetic screen in Chlamydia trachomatis, a common sexually transmitted human pathogen, and identified a mutant that caused premature death in the majority of infected host cells. We employed emerging genetic tools in Chlamydia to link this cytotoxicity to the loss of the protein CpoS (Chlamydia promoter of survival that normally localizes to the membrane of the pathogen-containing vacuole. CpoS-deficient bacteria also induced an exaggerated type-1 interferon response in infected cells, produced reduced numbers of infectious EBs in cell culture, and were cleared faster from the mouse genital tract in a transcervical infection model in vivo. The analysis of this CpoS-deficient mutant yielded unique insights into the nature of cell-autonomous defense responses against Chlamydia and highlighted the importance of Chlamydia-mediated control of host cell fate for the success of the pathogen.

    Procedures used to induce affect in a laboratory are effective and well-validated. Given recent methodological and technological advances in Internet research, it is important to determine whether affect can be effectively induced using Internet methodology. We conducted a meta-analysis and systematic review of prior research that has used Internet-based affect induction procedures, and examined potential moderators of the effectiveness of affect induction procedures. Twenty-six studies were included in final analyses, with 89 independent effect sizes. Affect induction procedures effectively induced general positive affect, general negative affect, fear, disgust, anger, sadness, and guilt, but did not significantly induce happiness. Contamination of other nontarget affect did not appear to be a major concern. Video inductions resulted in greater effect sizes. Overall, results indicate that affect can be effectively induced in Internet studies, suggesting an important venue for the acceleration of affective science.

    The Leibniz Institute for Applied Geosciences (GGA-Institut) is setting up an internet based information system on geothermal resources in close collaboration with partners. For a start, the geothermal information system will contain data about hydrogeothermal resources only. The project aims at an improvement of quality in the planning of geothermal plants and at a minimization of exploration risks. The key parameters for this purpose are production rate (Q) and temperature (T). The basis for the estimation of subsurface hydraulic properties comes from the information system on hydrocarbons. This information system provides permeability and porosity values derived from the analyses of drilling cores. The IT targets will be realised by a relational database providing all data relevant to the project. A 3D model of the ground provides the basis for visualisation and calculation of geothermal resources. As a prototype, a data-recall facility of geothermal sites in Germany is available online.

    2011-11-01

    Biotin is an essential water-soluble vitamin crucial for maintaining normal body functions. The importance of biotin for human health has been under-appreciated but there is plenty of opportunity for future research with great importance for human health. Currently, carrying out predictions of biotin metabolism involves tedious manual manipulations. In this paper, we report the development of BiotinNet, an internet based program that uses Bayesian networks to integrate published data on various aspects of biotin metabolism. Users can provide a combination of values on the levels of biotin related metabolites to obtain the predictions on other metabolites that are not specified. As an inherent feature of Bayesian networks, the uncertainty of the prediction is also quantified and reported to the user. This program enables convenient in silico experiments regarding biotin metabolism, which can help researchers design future experiments while new data can be continuously incorporated.

    Before launching a new study pilot testing is often recommended, however, it is seldom described in depth. Here, we report extensively on a pilot study using the internet as a new method for recruitment and data collection in a prospective cohort study of women planning a pregnancy.We aimed to enroll 2500 participants in six months and attained more than 75 % after 12 months follow up. To test data completeness and validity we randomized participants to fill either a long or a short version of the baseline questionnaire and compared self reported data with registry based data.We succeeded in enrolling 2288 participants, and participation rate was 82 % after 12 months. We found high correlations (0.96) for self-reported vs. registry based data and no difference in participation rate or data completeness according to questionnaire length. Overall, the internet based methods seem promising and we plan to launch the full study.

    To compare the effectiveness of small-group training in correct inhaler technique with self-directed Internet-based training. Pharmacy students were randomly allocated to 1 of 2 groups: small-group training (n = 123) or self-directed Internet-based training (n = 113). Prior to intervention delivery, all participants were given a placebo Turbuhaler and product information leaflet and received inhaler technique training based on their group. Technique was assessed following training and predictors of correct inhaler technique were examined. There was a significant improvement in the number of participants demonstrating correct technique in both groups (small group training, 12% to 63%; p training, 9% to 59%; p groups in the percent change (n = 234, p > 0.05). Increased student confidence following the intervention was a predictor for correct inhaler technique. Self-directed Internet-based training is as effective as small-group training in improving students' inhaler technique.

    Internet-based surveillance methods for vector-borne diseases (VBDs) using "big data" sources such as Google, Twitter, and internet newswire scraping have recently been developed, yet reviews on such "digital disease detection" methods have focused on respiratory pathogens, particularly in high-income regions. Here, we present a narrative review of the literature that has examined the performance of internet-based biosurveillance for diseases caused by vector-borne viruses, parasites, and other pathogens, including Zika, dengue, other arthropod-borne viruses, malaria, leishmaniasis, and Lyme disease across a range of settings, including low- and middle-income countries. The fundamental features, advantages, and drawbacks of each internet big data source are presented for those with varying familiarity of "digital epidemiology." We conclude with some of the challenges and future directions in using internet-based biosurveillance for the surveillance and control of VBD.

    To assess the use of Internet-based portals among families of children with chronic diseases and to describe characteristics of portal registrants and users. Retrospective observational study. Cincinnati Children's Hospital Medical Center, Cincinnati, Ohio, using data from September 1, 2003, through February 29, 2008. Patients/ Parents of children with diabetes mellitus, juvenile idiopathic arthritis, or cystic fibrosis. Parents of children with a chronic disease were given the opportunity to access health-related information for their children via an Internet-based portal. Percentage of families who obtained a portal account (registered), used the portal for the first time within 3 months and again 3 to 6 months after registration, number of times logged in, and session length. Of 1900 families, 27.9% obtained a portal account. Of those, 47.8% used the portal within 3 months of registration and 15.9% continued to use the portal 3 to 6 months after registration. Families of African American patients and of patients insured by Medicaid were less likely to obtain a portal account. More outpatient visits and having private health insurance coverage were associated with increased portal registration and use. Understanding the feasibility of portal use by parents is an important first step to using portals for improving self-management, patient-provider interactions, and outcomes for children with chronic diseases. Subsequent studies should address parent perceptions of the value portals add to the management of the chronic disease of their child and ways to increase that value. Barriers to using portals among racial minorities and publicly insured families should also be studied to address disparities.

    The aim of this paper was to describe the process of developing an Internet-based empowering patient education program for breast cancer patients and to evaluate the quality of the program from the perspective of patients. In this program, the patient pathway was used as an educational tool. The Breast Cancer Patient Pathway (BCPP) was developed and tested at one Finnish university hospital in 2005-2007. Thirty-eight newly diagnosed breast cancer patients used the program during their treatment process until the end of all treatments (average 9 months) in 2008-2010. After the treatments the patients evaluated the content, language and structure, instructiveness, external appearance and technical characteristics of the web site as subcategories with the Evaluating Internet Pages of Patient Education instrument, which is a 37-item Likert scale (1-4) questionnaire. Comparison between the subcategories was done with Friedman's test. Dependencies between demographic variables and evaluation values were tested with Pearson correlation coefficients. The mean value of all evaluation criteria was 3.40. However, patients' evaluations between different subcategories varied, being the highest in language and structure (mean 3.48) and lowest in content (mean 3.13). Language and structure, external appearance and technical characteristics were significantly better than content, and language and structure better than instructiveness. Significant correlations were not found between demographic variables and evaluation values. Patients evaluated the quality of the BCPP to be best in language and structure and weakest in content. In terms of future development of the BCPP, the most improvement is needed in content and instructiveness. There is also a need for further development and study of Internet-based patient education.

    Erik Hedman

    Full Text Available Personality traits have traditionally been viewed as stable, but recent studies suggest that they could be affected through psychological treatment. Internet-based cognitive behavior therapy (ICBT for severe health anxiety (DSM-IV hypochondriasis has been shown to be effective in reducing health anxiety, but its effect on measures of personality traits has not been investigated. The main aim of this study was to investigate the impact of ICBT on personality traits in the three broad dimensions--neuroticism, extraversion and aggression. We hypothesized that participants in ICBT would reduce their level of neuroticism compared to controls that did not receive the active treatment. No specific predictions were made regarding extraversion and aggression. Data from a randomized controlled trial were used in which participants were allocated to 12 weeks of ICBT (n = 40 or to a basic attention control condition (n = 41. Personality traits were assessed with the Swedish Universities Scales of Personality and the primary outcome of health anxiety was the Health Anxiety Inventory. There was a significant interaction effect of group and time on neuroticism-related scales, indicating larger pre- to post-treatment reductions in the Internet-based CBT group compared to the control condition. Analyses at 6-month follow-up showed that changes were stable. Traits relating to extraversion and aggression were largely unchanged. This study is the first to demonstrate that a brief ICBT intervention for severe health anxiety causes long-term changes in measures of personality traits related to neuroticism. The treatment thus has a broader impact than just reducing health anxiety.Clinicaltrials.gov (ID NCT00828152.

    The uses of internet-based technologies (e.g. patient portals, websites and applications) by cancer patients could be strong drive for change in cancer care coordination practices. The goal of this study was to assess the current utilisation of internet-based technologies (IBT) among cancer patients, and their willingness to use them for their health, as well as analyse the influence of socio-demographics on both aspects. A questionnaire-based survey was conducted in June 2013, over seven non-consecutive days within seven outpatient departments of Gustave Roussy, a comprehensive cancer centre (≈160,000 consultations yearly), located just outside Paris. We computed descriptive statistics and performed correlation analysis to investigate patients' usage and attitudes in correspondence with age, gender, socioeconomic status, social isolation, and place of living. We then conducted multinomial logistic regressions using R. The participation level was 85% (n=1371). The median age was 53.4. 71% used a mobile phone everyday and 93% had access to Internet from home. Age and socioeconomic status were negatively associated with the use of IBT (p<0.001). Regarding patients' expected benefits, a wide majority valued its use in health care, and especially, the possibility to enhance communication with providers. 84% of patients reported feeling comfortable with the use of such technologies but age and socioeconomic status had a significant influence. Most patients used IBTs every day. Overall, patients advocated for an extended use of IBT in oncology. Differences in perceived ease of use corresponding to age and socioeconomic status have to be addressed. Copyright © 2014 Elsevier Ltd. All rights reserved.

  4. The emergence of internet-based virtual private networks in international safeguards

    Full text: The costs associated with secure data transmission can be an obstacle to International Safeguards. Typical communication methods are priced by distance and may include telephone lines, frame relay, and ISDN. It is therefore costly to communicate globally. The growth of the Internet has provided an extensive backbone for global communications; however, the Internet does not provide intrinsic security measures. Combining the Internet with Virtual Private Network technology, which encrypts and authenticates data, creates a secure and potentially cost-effective data transmission path, as well as achieving other benefits such as reliability and scalability. Access to the Internet can be achieved by connecting to a local Internet Service Provider, which can be preferable to installing a static link between two distant points. The cost-effectiveness of the Internet-based Virtual Private Network is dependent on such factors as data amount, current operational costs, and the specifics of the Internet connection, such as user proximity to an Internet Service Provider or existing access to the Internet. This paper will introduce Virtual Private Network technology, the benefits of Internet communication, and the emergence of Internet-based Virtual Private Networks throughout the International Safeguards community. Specific projects to be discussed include: The completed demonstration of secure remote monitoring data transfer via the Internet between STUK in Helsinki, Finland, and the IAEA in Vienna, Austria; The demonstration of secure remote access to IAEA resources by traveling inspectors with Virtual Private Network software loaded on laptops; The proposed Action Sheets between ABACC/DOE and ARN/DOE, which will provide a link between Rio de Janeiro and Buenos Aires; The proposed use at the HIFAR research reactor, located in Australia, to provide remote monitoring data to the IAEA; The use of Virtual Private Networks by JRC, Ispra, Italy.

    Problem or pathological gambling has been a worldwide concern in the recent years, especially so with the advances in the technology, facilitating easier access to various means of gambling. Along with the advances in web-based and smartphone technologies, these technologies have been recently applied as adjunctive clinical tools to help gamblers. Taking into careful consideration the existing evidence base for Internet based interventions for pathological gambling, it seemed that the current published literature has demonstrated largely the efficacy of a personalized feedback intervention for pathological gambling; and further studies are still under-going to try and demonstrate the clinical feasibility of online web-based cognitive behavioral interventions for pathological gamblers. Given this, the aims of the current study are to (a) replicate an online personalized feedback intervention and determine its receptiveness in an Asian cohort of gamblers; and (b) to identify the demographics and characteristics of Asian gamblers who would utilize an online intervention. The workgroup at the National Addiction Management Service, Singapore conceptualized the online personalized feedback intervention for gamblers. The English version was launched on the 31st of March 2014 and the Chinese version was launched on the 30th of September 2014. A cumulative total of 708 participants took part with rhe mean age of the participants being 32.70 (SD = 11.638), with 89.1% males and 10.9% females. The mean problem gambling severity score (PGSI) was 10.80 (SD = 8.13), with the vast majority participating in Casino gambling on board a cruise (36.0%). Of significance, approximately 59.2% of the participants who sought help with our online e-intervention did have a diagnosis of problem gambling. This is one of the first few studies to demonstrate and replicate the potential use of an Internet based intervention for non-problem and problem gamblers. The current study has demonstrated

    Objective Preliminary evidence suggests that omega-3 fatty acids may reduce hyperactivity in children with autism spectrum disorder (ASD). We sought to examine the feasibility of a novel, internet-based clinical trial design to evaluate the efficacy of this supplement. Method E-mail invitations were sent to parents of children aged 5-8 enrolled in the Interactive Autism Network. All study procedures, including screening, informed consent, and collection of outcome measures took place over the internet. The primary outcome measures were parent- and teacher-rated changes in hyperactivity on the Aberrant Behavior Checklist. Results During the 6-week recruitment period, 57 children from 28 states satisfied all eligibility criteria and were randomly assigned to 1.3 grams of omega-3 fatty acids or an identical placebo daily for 6 weeks. Outcome assessments were obtained from all 57 participants and 57 teachers, and the study was completed in 3 months. Children in the omega-3 fatty acid group had a greater reduction in hyperactivity (-5.3 points) compared to the placebo group (-2.6 points), but the difference was not statistically significant (1.9 point greater improvement in the omega-3 group, 95% CI -2.2 to 5.2). Side effects were rare and not associated with omega-3 fatty acids. Participant feedback was positive. Conclusion Internet-based randomized controlled trials of therapies in children with ASD are feasible and may lead to marked reductions in the time and cost of completing trials. A larger sample size is required to definitively determine the efficacy of omega-3 fatty acids.

    2015-04-01

    Full Text Available Background: Posttraumatic stress disorder (PTSD develops in approximately 20% of people exposed to a traumatic event, and studies have shown that cognitive-behavioral therapy (CBT is effective as a treatment for chronic PTSD. It has also been shown to prevent PTSD when delivered early after a traumatic event. However, studies have shown that uptake of early treatment is generally low, and therefore, the need to provide interventions through other mediums has been identified. The use of technology may overcome barriers to treatment. Objective: This paper describes a randomized controlled trial that will examine an early CBT intervention for PTSD. The treatment incorporates virtual reality (VR as a method for delivering exposure-based elements of the treatment. The intervention is Internet based, such that the therapist and patient will “meet” in a secure online site. This site will also include multi-media components of the treatment (such as videos, audios, VR that can be accessed by the patient between sessions. Method: Two hundred patients arriving to a Level 1 emergency department following a motor vehicle accident will be randomly assigned to either treatment or control groups. Inclusion criteria are age 18–65, PTSD symptoms 2 weeks posttrauma related to current trauma, no suicidality, no psychosis. Patients will be assessed by telephone by a team blind to the study group, on four occasions: before and after treatment, and 6 and 12 months posttreatment. The primary outcome is PTSD symptoms at follow up. Secondary outcomes include depression and cost effectiveness. Analyses will be on an intention-to-treat basis. Discussion: The results will provide more insight into the effects of preventive interventions, in general, and Internet-based early interventions, in particular, on PTSD, in an injured population, during the acute phase after trauma. We will discuss possible strengths and limitations.

    Knowledge regarding the importance of sleep in health and performance and good sleep hygiene practices is low, especially among adolescents and young adults. It is important to improve sleep literacy. Introductory psychology is one of the most highly enrolled courses at colleges and universities. This study tested the impact of an Internet-based learning module on improving sleep literacy in this venue. An Internet-based supplementary learning module containing sleep physiology and hygiene information was developed using content from the Harvard Medical School sleep educational website http://www.understandingsleep.org. Access to the module was provided as an extra credit activity for 2 of 4 sections (Supplemental Sleep, SS, N = 889) of an introductory college psychology course during their standard instruction on sleep and dreaming. The remaining 2 sections (Standard Instruction, SI, N = 878) only were encouraged to visit the website without further direction. Level of knowledge was assessed before and after availability to the module/website and at the end of the semester. Students were asked to complete a survey at the end of the semester inquiring whether they made any changes in their sleep behaviors. Two hundred fifty students participated in the extra credit activity and had data available at all testing points. Students in the SS Group had a significant improvement in sleep knowledge test scores after interacting with the website in comparison to the SI group (19.41 ± 3.15 vs. 17.94 ± 3.08, p students enrolled in an introductory college psychology course.

    Use of the World Wide Web (WWW) and electronic media to facilitate medical care has been the subject of many reports in the popular press. However, few reports have documented the results of implementing electronic health portals for essential medical tasks, such as prescription refills and appointments. At Walter Reed Army Medical Center, "Search & Learn" medical information, Internet-based prescription refills and patient appointments were established in January 2001. A multiphase retrospective analysis was conducted to determine the use of the "Search & Learn" medical information and the relative number of prescription refills and appointments conducted via the WWW compared with conventional methods. From January 2001 to May 2002, there were 34,741 refills and 819 appointments made over the Internet compared with 2,275,112 refills and approximately 500,000 appointments made conventionally. WWW activity accounted for 1.52% of refills and 0.16% of appointments. There was a steady increase in this percentage over the time of the analysis. In April of 2002, the monthly average of online refills had risen to 4.57% and online appointments were at 0.27%. Online refills were projected to account for 10% of all prescriptions in 2 years. The "Search & Learn" medical information portion of our web site received 147,429 unique visits during this same time frame, which was an average of 326 visitors per day. WWW-based methods of conducting essential medical tasks accounted for a small but rapidly increasing percentage of total activity at Walter Reed Army Medical Center. Subsequent phases of analysis will assess demographic and geographic factors and aid in the design of future systems to increase use of the Internet-based systems.

    Procrastination can be a persistent behavior pattern associated with personal distress. However, research investigating different treatment interventions is scarce, and no randomized controlled trial has examined the efficacy of cognitive-behavior therapy (CBT). Meanwhile, Internet-based CBT has been found promising for several conditions, but has not yet been used for procrastination. Participants (N = 150) were randomized to guided self-help, unguided self-help, and wait-list control. Outcome measures were administered before and after treatment, or weekly throughout the treatment period. They included the Pure Procrastination Scale, the Irrational Procrastination Scale, the Susceptibility to Temptation Scale, the Montgomery Åsberg Depression Rating Scale-Self-report version, the Generalized Anxiety Disorder Assessment, and the Quality of Life Inventory. The intention-to-treat principle was used for all statistical analyses. Mixed-effects models revealed moderate between-groups effect sizes comparing guided and unguided self-help with wait-list control; the Pure Procrastination Scale, Cohen's d = 0.70, 95% confidence interval (CI) [0.29, 1.10], and d = 0.50, 95% CI [0.10, 0.90], and the Irrational Procrastination Scale, d = 0.81 95% CI [0.40, 1.22], and d = 0.69 95% CI [0.29, 1.09]. Clinically significant change was achieved among 31.3-40.0% for guided self-help, compared with 24.0-36.0% for unguided self-help. Neither of the treatment conditions was found to be superior on any of the outcome measures, Fs(98, 65.17-72.55) .19. Internet-based CBT could be useful for managing self-reported difficulties due to procrastination, both with and without the guidance of a therapist. (c) 2015 APA, all rights reserved).

    A prospective study of 505 unselected women presenting for induced abortion was undertaken to determine the prevalence of Chlamydia trachomatis and to determine if cervical isolation of C trachomatis before abortion increases the risk of postabortal endometritis. A comparison of direct fluorescent antibody (slide) test with tissue culture for diagnosing C trachomatis infection also was evaluated in this population. C trachomatis was identified by culture in 89 patients (17.6%) and by direct slide test in 85 patients (16.8%). Six of 17 patients with postabortal endometritis were culture positive for C trachomatis, with a significant correlation between C trachomatis infection and development of endometritis observed (P less than .05). These data suggest C trachomatis may play an important role in postabortal endometritis.

    Full Text Available There is a well-known correlation between Herpes simplex (HSV infection and erythema multiforme (EM. More recently, in Japan, it was found that Chlamydia pneumoniae (Cp may promote the development of EM. All cases of Cp infection-associated EM that had been diagnosed in our clinic over the past two years (from 2011 to 2012 were analyzed. Cp infection was diagnosed on the basis of a significant increase (>2.00 in anti-Cp IgM titers, as measured by the HITAZYME-ELISA test. There were 7 cases of Cp-EM, one male and 6 females. Median age was 13 years (range 3-29 years. It is recommended that the possible involvement of Cp infection, besides HSV or Mycoplasma pneumoniae infections, should be considered in all cases of EM.

  13. Laboratory Diagnosis of Chlamydia Pneumoniae Infections

    Rosanna W Peeling

    1995-01-01

    Full Text Available Chlamydia pneumoniae is an important cause of respiratory illness. There is a need for accurate and rapid laboratory diagnostic methods that will lead to improved patient care, appropriate use of antimicrobial therapy and a better understanding of the epidemiology of this emerging pathogen. Culture is highly specific but is technically demanding, expensive, has a long turnaround time and its sensitivity is highly dependent on transport conditions. Antigen detection tests such as enzyme immunoassay and direct fluorescent antibody assay, and molecular detection methods such as the polymerase chain reaction assay, may provide a rapid diagnosis without the requirement for stringent transport conditions. The results of these tests should be interpreted with caution until more thorough evaluation is available. Serology remains the method of choice. The limitations of different serological methods for the laboratory diagnosis of C pneumoniae are discussed.

    Results from clinical trials indicate that Internet-based psychological pain interventions are effective in treating chronic pain. However, little is known about patients' acceptance of these programs and how to positively influence patients' intention to engage in them. Therefore, the present study aimed (1) to assess patients' acceptance of Internet-based interventions, and (2) to examine whether patients' acceptance can be increased by an acceptance facilitating intervention. A total of 104 patients with chronic pain from 2 pain units were randomly allocated to an intervention group (IG) and a no-intervention control group (CG). The IG was shown a short informational video about Internet-based psychological pain interventions before receiving a questionnaire on patients' acceptance of Internet-based psychological pain interventions and predictors of acceptance (performance expectancy, effort expectancy, social influence, facilitating conditions, Internet usage, and Internet anxiety). The CG filled out the questionnaire immediately. Patients' acceptance was measured with a 4-item scale (sum score ranging from 4 to 20). Baseline acceptance of Internet-based interventions was reported as low (sum-score:4-9) by 53.8%, moderate (10 to 15) by 42.3%, and high (16 to 20) by 3.9% of the patients with chronic pain in the CG. The IG showed a significantly higher acceptance (M = 12.17, SD = 4.22) than the CG (M = 8.94, SD = 3.71) with a standardized mean difference of d = 0.81 (95% CI, 0.41, 1.21). All predictor variables were significantly improved in the IG compared with the CG, except for Internet usage. Patients with chronic pain display a relatively low acceptance of Internet-based psychological pain interventions, which can be substantially increased by a short informational video.

    Bacterial vaginosis is a frequent dysbiosis, where the normal lactobacillus-dominated flora is replaced by an anaerob/aerob polymicrobial flora. Bacterial vaginosis increases the risk of acquiring sexually transmitted infections (STI) including the most frequent Chlamydia trachomatis infections. Intravaginal antiseptics are part of the bacterial vaginosis treatment, and ideally they should also inhibit the bacterial vaginosis-related STI. Therefore, we tested the antichlamydial activity of four antiseptics: iodine aqueous solution, povidone-iodine, chlorhexidine and borax. First, we measured the impact of antiseptics on the viability of the HeLa cervical epithelial cells, and calculated the maximum nontoxic concentrations. Next, we infected the cells with C. trachomatis preincubated for 1 h with the particular antiseptic. The chlamydial growth was measured by direct quantitative PCR (qPCR) of the infected cells. The minimal inhibitory concentrations (MIC) of chlorhexidine and povidone-iodine were 3·91 and 97 μg ml(-1) respectively; however, the MIC of chlorhexidine was close to its maximum nontoxic concentration. The iodine aqueous solution and the borax showed no antichlamydial activity. Our in vitro studies showed that chlorhexidine and particularly povidone-iodine are potentially able to limit the bacterial vaginosis-related C. trachomatis infection. We measured the antichlamydial effects of various antiseptics. These antiseptics are being used for the treatment of bacterial vaginosis, but their effect on the bacterial vaginosis-related sexually transmitted infections, particularly the most frequent Chlamydia trachomatis (C. trachomatis) infections has not been investigated. We showed that povidone-iodine (Betadine) inhibited the chlamydial growth in concentrations that was not toxic to the epithelial cells. We concluded that due to its additional antichlamydial effect, povidone-iodine could be a preferable antiseptic in bacterial vaginosis treatment.

    Full Text Available Objective To evaluate the effectiveness of internet-based cognitive behavior therapy (CBT-I on blood pressure in patients with hypertension comorbid with insomnia. Methods One hundred and six patients met the JNC-8 diagnostic criteria for hypertension and DSM-5 diagnostic criteria for insomnia were selected, and randomly assigned to CBT-I group (n=53 and regular treatment group (n=53. All the patients accepted relevant treatment for 8 consecutive weeks. Changes of systolic blood pressure (SBP, diastolic blood pressure (DBP, the sleep parameters and the anxiety and depression levels were observed between baseline and 8 weeks of follow-up. Results Compared with pre-treatment, SBP and DBP decreased significantly in both CBT-I group and regular treatment group (P<0.01, the decrease was more significant in CBT-I group than in regular treatment group (P<0.01. The sleep latency, sleep efficiency, bed time and rating anxiety scale were improved more significantly in CBT-I group than in regular treatment group (44.49±22.75min vs. 55.50±34.96min; 72.31%±9.15% vs. 57.70%±11.53%; 302.65±43.76min vs. 262.70±50.64min and 17.14±6.45 vs. 21.02±6.64, respectively, the differences were of statistical significance (P<0.05. In addition, no significant difference was found in the level of depression between CBT-I group and regular treatment group. Conclusion CBT-I can effectively shorten sleep latency, improve sleep efficiency, extend bed time and improve anxiety, meanwhile effectively lower the blood pressure of patients with hypertension comorbid with insomnia by optimizing sleep quality.

    To provide oral healthcare for patients of all ages, dental welfare environments and technical aspects of dentistry have evolved and developed and dental education must also diversify. Student-centered voluntary education and establishment of a life-long self-learning environment are becoming increasingly important in the changing world of dental education. In this article, we introduce a new process for the construction of a web-mediated database containing internet-based teaching files on the normal radiological anatomy of panoramic radiographs and CT images of the oral and maxillofacial regions, as well as a system for the delivery of visual learning materials through an intra-faculty local network. This process was developed by our 5th-year undergraduate students. Animated CT scan images were produced using Macintosh Iphoto and Imovie animation software. Normal anatomical images of panoramic radiographs and CT scans were produced using Adobe Illustrator CS and Adobe Photoshop CS. The web database was constructed using Macromedia Dreamweaver MX and Microsoft Internet Explorer. This project was the basis of our participation in the Student Clinician Research Program (SCRP). At Kyushu Dental College, we developed a new series of teaching files on the web. Uploading these teaching files to the internet allowed many individuals to access the information. Viewers can easily select the area of study that they wish to examine. These processes suggest that our laboratory practice is a useful tool for promoting students' motivation and improving life-long self learning in dental radiology. We expect that many medical and dental students, practitioners and patients will be able to use our teaching files to learn about the normal radiological anatomy of the oral and maxillofacial regions.(author)

    Full Text Available Published in 1996, the Standards far Foreign Language Learning (Standards, define knowledge and abilities that foreign language learners should acquire in the U.S. The Internet is believed to facilitate standards-based instruction because of its capabilities as a communication medium, information provider, and publication tool. This paper presents one part of a study that investigated this claim through examining an Internet-based newspaper project in an advanced-level college Japanese course in light of the Japanese Standards. Six students were selected to serve as case studies, with their experiences in relation to this project analyzed in depth. The results show that the students found using the Internet to read authentic materials with the help of an online dictionary to be a positive experience. This then resulted in their actively using Japanese for personal enjoyment outside the classroom. These results suggest that the project was particularly successful in two goal areas: Communication and Communities.

    Full Text Available Chlamydia causes infertility and increases risk of HIV infection, and population-based studies provide essential information for effective infection control and prevention. This study examined Chlamydia trachomatis prevalence and risk factors among a representative sample of 18-49-year-old residents in Hong Kong.Census boundary map of 412 constituency areas was used as primary sampling units to construct the sampling frame and, residential buildings and units were randomly selected using geospatial modelling. A questionnaire on sexual practice and health was conducted, and polymerase chain reaction was used to test the urine for genital chlamydial infection. Invitation letters were sent to the selected households and a team of interviewers were sent to recruit one subject per household. Prevalence data was weighted according to the 2011 census and risk factors identified through logistic regression.Among 881 participants (response rate of 24.5%, the overall Chlamydia trachomatis prevalence was low at 1.4% (95%CI 0.8-2.5% but sexually active young (18-26 years women had relatively high prevalence (5.8%, 95%CI 1.7-18.2% in Hong Kong. A unique U-shape disease burden was observed with peaks in younger and older (40-49 years women. Amongst the sexually active women, the risk factors of Chlamydia trachomatis infection were: younger age (aOR = 25.4, 95% CI 2.81-230; living alone (aOR = 8.99, 95% CI 1.46-55.40; and, among all the sexually active participants, males (including the male partners of the female participants who had travelled out of Hong Kong in the previous 12 months had higher risks of infection (aOR = 5.35; 95% CI 1.25-22.8. A core-peripheral geographical distribution of Chlamydia trachomatis prevalence was also observed.Young and older sexually active women in Hong Kong have high prevalence of chlamydia. Routine screening for sexually active women and young men should be considered. Further research on testing feasibility and linkage

    Full Text Available Introduction: Internet-based guided self-help and face-to-face CBT have shown to be effective in the treatment of depression, but both approaches might not be an available treatment option for all patients. A treatment which blends internet-based guided self-help with video-based psychotherapy might reduce potential disadvantages of both approaches, while maintaining major advantages such as being location-independent. Additionally, it could provide a stronger focus on patient empowerment and lower resource use compared to traditional face-to-face treatment. Aim: The aim of this study is to evaluate patient's experiences with blended internet- and video-based CBT (blended iCBT treatment and to derive suggestions for the improvement of such services. Methods: Semi-structured interviews were conducted with 15 participants of the blended iCBT treatment as part of the European MasterMind trial. Participants included adults suffering from Major Depressive Disorder. The interview guide assessed patient's experiences regarding the four treatment components program, 1. face-to-face diagnostic interviews, 2. video-based synchronous therapy sessions (VTS, 3. online self-help treatment modules (OTM as well as 4. behaviour diaries and symptom monitoring. Interviews were analyzed using the framework method and outcomes regarding connections within and between participants and categories were generated by counting the statements within relevant themes. Results: Overall, patients indicated to have been satisfied with all components of the treatment, highlighting the option to independently work from home in their own pace. While the OTMs allowed for a deeper reflection of the content, the VTS with the therapist were mentioned to provide the personal character of the service. The working alliance with the therapist was experienced as fostering the individual fit of the treatment. Patients reported a high self-perceived treatment effectiveness. Negative effects

    Internet-based interventions moderated by community nurses have the potential to improve support offered to new mothers, many of whom now make extensive use of the Internet to obtain information about infant care. However, evidence from population-based randomized controlled trials is lacking. The aim of this study was to test the non-inferiority of outcomes for mothers and infants who received a clinic-based postnatal health check plus nurse-moderated, Internet-based group support when infants were aged 1-7 months as compared with outcomes for those who received standard care consisting of postnatal home-based support provided by a community nurse. The design of the study was a pragmatic, preference, non-inferiority randomized control trial. Participants were recruited from mothers contacted for their postnatal health check, which is offered to all mothers in South Australia. Mothers were assigned either (1) on the basis of their preference to clinic+Internet or home-based support groups (n=328), or (2) randomly assigned to clinic+Internet or home-based groups if they declared no strong preference (n=491). The overall response rate was 44.8% (819/1827). The primary outcome was parenting self-competence, as measured by the Parenting Stress Index (PSI) Competence subscale, and the Karitane Parenting Confidence Scale scores. Secondary outcome measures included PSI Isolation, Interpersonal Support Evaluation List-Short Form, Maternal Support Scale, Ages and Stages Questionnaire-Social-Emotional and MacArthur Communicative Development Inventory (MCDI) scores. Assessments were completed offline via self-assessment questionnaires at enrolment (mean child age=4.1 weeks, SD 1.3) and again when infants were aged 9, 15, and 21 months. Generalized estimating equations adjusting for post-randomization baseline imbalances showed that differences in outcomes between mothers in the clinic+Internet and home-based support groups did not exceed the pre-specified margin of

    Internet has become a major tool for patients to search for health-related information and to communicate on health. We currently lack data on how patients with psychiatric disorders access and use Internet to search for information on their mental health. This study aimed to assess, in patients followed for a psychiatric disorder (schizophrenia, bipolar disorder, mood and anxiety disorder, substance-related and addictive disorders and eating disorders), prevalence of Internet access and use, and patient expectations and needs regarding the use of Internet to search for mental-health information depending on the psychiatric disorder. We conducted this cross-sectional study between May 2013 and July 2013 in 648 patients receiving psychiatric care in 8 hospitals from the Region Centre, France. We used multivariate logistic regression adjusted for age, gender, socio-educational level and professional status to compare use, expectations and needs regarding Internet-based information about the patient's psychiatric disorder (65-items self-administered questionnaires) as a function of the psychiatric disorders. We identified patients clusters with multiple correspondence analysis and ascending hierarchical classification. Although 65.6% of our population accessed Internet at home, prevalence for Internet access varied depending on the type of psychiatric disorder and was much more related to limited access to a computer and low income than to a lack of interest in the Internet. Most of the patients who used Internet were interested in having access to reliable Internet-based information on their health (76.8%), and most used Internet to search for Internet based health-information about their psychiatric disorder (58.8%). We found important differences in terms of expectations and needs depending on the patient's psychiatric disorder (e.g., higher interest in Internet-based information among patients with bipolar disorder, substance-related and addictive disorders

    Adjustment Disorder (AjD) is a common and disabling mental health problem. The lack of research on this disorder has led to the absence of evidence-based interventions for its treatment. Moreover, because the available data indicate that a high percentage of people with mental illness are not treated, it is necessary to develop new ways to provide psychological assistance. The present study describes a Randomized Controlled Trial (RCT) aimed at assessing the effectiveness and acceptance of a linear internet-delivered cognitive-behavioral therapy (ICBT) intervention for AjD. A two-armed RCT was designed to compare an intervention group to a waiting list control group. Participants from the intervention group will receive TAO, an internet-based program for AjD composed of seven modules. TAO combines CBT and Positive Psychology strategies in order to provide patients with complete support, reducing their clinical symptoms and enhancing their capacity to overcome everyday adversity. Participants will also receive short weekly telephone support. Participants in the control group will be assessed before and after a seven-week waiting period, and then they will be offered the same intervention. Participants will be randomly assigned to one of the 2 groups. Measurements will be taken at five different moments: baseline, post-intervention, and three follow-up periods (3-, 6- and 12-month). BDI-II and BAI will be used as primary outcome measures. Secondary outcomes will be symptoms of AjD, posttraumatic growth, positive and negative affect, and quality of life. The development of ICBT programs like TAO responds to a need for evidence-based interventions that can reach most of the people who need them, reducing the burden and cost of mental disorders. More specifically, TAO targets AjD and will entail a step forward in the treatment of this prevalent but under-researched disorder. Finally, it should be noted that this is the first RCT focusing on an internet-based

    Responding to national science education reform documents calling for students to have more opportunities for authentic research experiences, several national projects have developed online telescope networks to provide students with Internet-access to research grade telescopes. The nature of astronomical observation (e.g., remote sites, expensive equipment, and odd hours) has been a barrier in the past. Internet-based robotic telescopes allow scientists to conduct observing sessions on research-grade telescopes half a world away. The same technology can now be harnessed by STEM educators to engage students and reinforce what is being taught in the classroom, as seen in some early research in elementary schools (McKinnon and Mainwaring 2000 and McKinnon and Geissinger 2002), middle/high schools (Sadler et al. 2001, 2007 and Gehret et al. 2005) and undergraduate programs (e.g., McLin et al. 2009). This project looks at the educational value of using Internet-based robotic telescopes in a general education introductory astronomy course at the undergraduate level. Students at a minority-serving institution in the midwestern United States conducted observational programs using the Global Telescope Network (GTN). The project consisted of the use of planetarium software to determine object visibility, observing proposals (with abstract, background, goals, and dissemination sections), peer review (including written reviews and panel discussion according to NSF intellectual merit and broader impacts criteria), and classroom presentations showing the results of the observation. The GTN is a network of small telescopes funded by the Fermi mission to support the science of high energy astrophysics. It is managed by the NASA E/PO Group at Sonoma State University and is controlled using SkyNet. Data includes course artifacts (proposals, reviews, panel summaries, presentations, and student reflections) for six semesters plus student interviews. Using a grounded theory approach

    Full Text Available Introduction: The clinical presentation of genital Chlamydia trachomatis infection (chlamydia in women is often indistinguishable from a urinary tract infection. While merited in the setting of dysuria, emergency department (ED clinicians do not routinely test for chlamydia in women. The primary aim of our study was to evaluate the frequency of chlamydia testing among women presenting to the ED with dysuria. Methods: We conducted a retrospective chart review of women 19-25 years of age presenting with dysuria to an urban ED and who had been coded with urinary tract infection (UTI as their primary diagnosis (ICD-9 599.0 from October 2005 to March 2011. We excluded women who were pregnant, had underlying anatomical or neurological urinary system pathology, had continuation of symptoms from UTI or a sexually transmitted infection (STI diagnosed elsewhere, or were already on antibiotics for a UTI or STI. We identified the rates of sexual history screening, pelvic examination and chlamydia assay testing and evaluated predictors using univariate and multivariate analyses. Results: Of 280 women with dysuria and a UTI diagnosis, 17% were asked about their sexual history, with 94% reporting recent sexual activity. Pelvic examination was performed in 23%. We were unable to determine the overall chlamydia prevalence as only 20% of women in the cohort were tested. Among the 20% of women tested for chlamydia infection, 21% tested positive. Only 42% of chlamydia-positive women were prescribed treatment effective for chlamydia (azithromycin or doxycycline at their visit; the remaining were prescribed UTI treatment not effective against chlamydia. Predictors of sexual history screening included vaginal bleeding (OR 5.4, 95% CI=1.5 to 19.6 and discharge (OR 2.8, 95% CI=1.1 to 6.9. Predictors of a pelvic examination being performed included having a complaint of vaginal discharge (OR 11.8, 95% CI=4.2 to 32.9, a sexual history performed (OR 2.5, 95% CI=1.1 to 5

    Since legislation prohibiting tobacco advertising in traditional media, online communication platforms and social media have become one of the few avenues for the tobacco industry to promote its products to Australians. Little is currently known about the exposure of young people to these new media promotions. To measure exposure to Internet-based tobacco advertising and branding among Australian youth, identify common formats of branding encountered, and examine the association between exposure and smoking susceptibility. The Tobacco Promotion Impact Study is a repeat cross-sectional telephone survey of young people (12-24 years) in 2 Australian states, conducted yearly from 2010 to 2013 (total n=8820). The survey included questions about past-month exposure to Internet-based tobacco advertising and tobacco company branding. Changes in levels of exposure, characteristics of exposed youth, and the association between exposure and smoking susceptibility were explored. Past-month exposure to Internet-based tobacco advertising and branding among young people increased over the years of the survey (advertising: 21% in 2010 to 29% in 2013; branding: 20% in 2010 to 26% in 2013). The participants who were younger, female, from lower socioeconomic status, and never-smokers were more likely to report exposure. Facebook was the most commonly cited platform for encountering tobacco branding in 2013 (22% of all branding). Compared with young people interviewed in 2013, participants in 2010 were significantly less likely to report exposure to tobacco branding on social media (odds ratio [OR] 0.26, 95% CI 0.20-0.33, Pbranding (OR 1.32, 95% CI 1.11-1.57, P=.002) or branding alone (OR 1.39, 95% CI 1.10-1.77, P=.007) were significant predictors of smoking susceptibility. Ensuring tobacco advertising bans are inclusive of Internet-based media is essential. Given the global nature of Internet-based content, cooperation among signatory nations to the World Health Organization

    Full Text Available Background: To date, little is known about treatment preferences for depression concerning new media. This study aims to (1 investigate treatment preferences for depression including internet-based interventions and (2 examine subgroup differences concerning age, gender and severity of depression as well as patient-related factors associated with treatment preferences.Methods: Data were derived from the baseline assessment of the @ktiv-trial. Depression treatment preferences were assessed from n = 641 primary care patients with mild to moderate depression regarding the following treatments: medication, psychotherapy, combined treatment, alternative treatment, talking to friends and family, exercise, self-help literature, and internet-based interventions. Depression severity was specified by GPs according to ICD-10 criteria. Ordinal logistic regression models were conducted to identify associated factors of treatment preferences.Results: Patients had a mean age of 43.9 years (SD = 13.8 and more than two thirds (68.6% were female. About 43% of patients had mild depression while 57% were diagnosed with moderate depression. The majority of patients reported strong preferences for psychotherapy, talking to friends and family, and exercise. About one in five patients was very likely to consider internet-based interventions in case of depression. Younger patients expressed significantly stronger treatment preferences for psychotherapy and internet-based interventions than older patients. The most salient factors associated with treatment preferences were the patients' education and perceived self-efficacy.Conclusions: Patients with depression report individually different treatment preferences.Our results underline the importance of shared decision-making within primary care. Future studies should investigate treatment preferences for different types of internet-based interventions.

    Internet-based interventions for depression may be a valuable resource to reduce the treatment gap for those living in developing countries. However, evidence comes mainly from developed countries. This systematic review summarized the evidence on preventive or therapeutic Internet-based interventions for depression for people who reside in developing countries. CINAHL, EMBASE, PubMed, SciELO Citation Indexes, the Journal of Medical Internet Research, and the Telemedicine and e-Health journal, were searched up to June 2017, to identify feasibility or effectiveness studies of preventive or therapeutic Internet-based interventions for depression, with or without human support. Studies included subjects residing in developing countries, and were published in English or Spanish. Study protocols were included. Risk of bias and/or quality of the reporting of the studies included was assessed. Five feasibility studies, aimed at the prevention of depression, and a study protocol were included in this systematic review. Reports came mostly from the Americas (n = 4). Internet-based interventions aimed at the prevention of depression presented low levels of human support, were useful and acceptable to their users, and require further design refinements to improve their use and retention. No gray literature was searched or included in this systematic review. Searches were limited to English and Spanish languages. Internet-based interventions aimed at the prevention of depression in people who reside in developing countries are in an early phase of development, limiting the generalizability of the results. Future studies must employ persuasive designs to improve user retention, incorporating larger samples and a control group to conclusively determine feasibility. Copyright © 2018 Elsevier B.V.

    Nongonococcal urethritis is the most common sexually transmitted infection in men, with vast majority of the etiological agents such as Chlamydia trachomatis, followed by urogenital mycoplasmas. The aim of this study was to determine the prevalence of Chlamydia trachomatis, Ureaplasma urealyticum and Mycoplasma hominis in nongonococcal urethritis in men, and to examine infections associated with these agents. Material and methods 299 sexually active, heterosexual men with nongonococcal urethritis were included into the study. Urethral samples were taken with a dacron swab placed into the urethra up to 2-3 cm. The Direct immunofluorescence technique was performed for identification of Chlamydia trachomatis. Ureaplasma urealyticum and Mycoplasma hominis were detected with Mycoplasma IST assay. Chlamydia trachomatis was detected in 22.75%, Uraeplasma urealyticum in 21.08% and Mycoplasma hominis in 8.02% cases. We found no significant differences in prevalence between Chlamydia trachomatis and Ureaplasma urealyticym (p > 0.05). Monoinfections were found in 51.85% with significantly higher rate (p urethritis with prevalence of 51.85% in monoinfections and 11.70% in associated infections. In 36.45% of cases the etiology of urethritis was not elucidated. These results suggest that more sensitive diagnostic tool should be applied when searching for the derailed etiology of nongonococcal urethritis.

  16. Thinking about online sources: Exploring students' epistemic cognition in internet-based chemistry learning

    Dai, Ting

    This dissertation investigated the relation between epistemic cognition---epistemic aims and source beliefs---and learning outcome in an Internet--based research context. Based on a framework of epistemic cognition (Chinn, Buckland, & Samarapungavan, 2011), a context--specific epistemic aims and source beliefs questionnaire (CEASBQ) was developed and administered to 354 students from college--level introductory chemistry courses. A series of multitrait--multimethod model comparisons provided evidence for construct convergent and discriminant validity for three epistemic aims--- true beliefs, justified beliefs, explanatory connection, which were all distinguished from, yet correlated with, mastery goals. Students' epistemic aims were specific to the chemistry topics in research. Multidimensional scaling results indicated that students' source evaluation was based on two dimensions--- professional expertise and first--hand knowledge, suggesting a multidimensional structure of source beliefs. Most importantly, online learning outcome was found to be significantly associated with two epistemic aims---justified beliefs and explanatory connection: The more students sought justifications in the online research, the lower they tended to score on the learning outcome measure, whereas the more students sought explanatory connections between information, the higher they scored on the outcome measure. There was a significant but small positive association between source beliefs and learning outcome. The influences of epistemic aims and source beliefs on learning outcome were found to be above and beyond the effects of a number of covariates, including prior knowledge and perceived ability with online sources.

  17. Fast Lemons and Sour Boulders: Testing Crossmodal Correspondences Using an Internet-Based Testing Methodology

    Full Text Available According to a popular family of hypotheses, crossmodal matches between distinct features hold because they correspond to the same polarity on several conceptual dimensions (such as active–passive, good–bad, etc. that can be identified using the semantic differential technique. The main problem here resides in turning this hypothesis into testable empirical predictions. In the present study, we outline a series of plausible consequences of the hypothesis and test a variety of well-established and previously untested crossmodal correspondences by means of a novel internet-based testing methodology. The results highlight that the semantic hypothesis cannot easily explain differences in the prevalence of crossmodal associations built on the same semantic pattern (fast lemons, slow prunes, sour boulders, heavy red; furthermore, the semantic hypothesis only minimally predicts what happens when the semantic dimensions and polarities that are supposed to drive such crossmodal associations are made more salient (e.g., by adding emotional cues that ought to make the good/bad dimension more salient; finally, the semantic hypothesis does not explain why reliable matches are no longer observed once intramodal dimensions with congruent connotations are presented (e.g., visually presented shapes and colour do not appear to correspond.

    The purpose of the study was to evaluate an Internet-based cognitive behavioral therapy (iCBT) program targeting difficulties and impairments associated with adult ADHD. Forty-five adults diagnosed with ADHD were randomized to either self-help (iCBT self-help format [iCBT-S]), self-help with weekly group sessions (iCBT group-therapy format [iCBT-G]), or a waiting-list control group. Treatment efficacy was measured at pre- and posttreatment and at 6-month follow-up. Intention-to-treat (ITT) analysis showed a significant reduction in ADHD symptoms for the iCBT-S group in comparison with the waiting-list controls at posttreatment, with a between-group effect size of d = 1.07. The result was maintained at 6-month follow-up. No significant difference was found at posttreatment or 6-month follow-up between the iCBT-S and iCBT-G groups. The findings show that a CBT treatment program administered through the Internet can be a promising treatment for adult ADHD. Limitations of the study design and directions for future research are discussed.

    UniNet is an Internet-based thematic network for a virtual community of users (VCU). It supports one multidisciplinary community of doctoral students, who receive most of the courses on the network. The evident advantages of distance learning by Internet, in terms of costs, comfort, etc., require a previous evaluation of the system, focusing on the learning outcomes of the student. The aim was to evaluate the real learning of the students of doctorate courses, by comparing the effectiveness of distance learning in UniNet with traditional classroom-based teaching. Five doctorate courses were taught simultaneously to two independent groups of students in two ways: one, through the UniNet Network, and the other in a traditional classroom. The academic knowledge of students was evaluated at the beginning and end of each course. The difference in score was considered as a knowledge increase. The comparison was made using Student's t-test for independent groups. There were no significant statistical differences in the outcomes of the two groups of students. This suggests that both teaching systems were equivalent in increasing the knowledge of the students. Both educational methods, the traditional system and the online system in a thematic network, are effective and similar for increasing knowledge.

    Depression is among the most prevalent disorders worldwide. In view of numerous treatment barriers, internet-based interventions are increasingly adopted to "treat the untreated". The present trial (registered as NCT01401296) was conducted over the internet and aimed to assess the efficacy of an online self-help program for depression (Deprexis). In random order, participants with elevated depression symptoms received program access or were allocated to a wait-list control condition. After eight weeks, participants were invited to take part in an online re-assessment. To compensate for common problems of online studies, such as low completion rates and unclear diagnostic status, reminders and incentives were used, and clinical diagnoses were externally confirmed in a subgroup of 29% of participants. Relative to the wait-list group, program users experienced significant symptom decline on the Beck Depression Inventory (BDI; primary outcome), the Dysfunctional Attitudes Scale (DAS), the Quality of Life scale (WHOQOL-BREF) and the Rosenberg Self-Esteem Scale (RSE). Compared to wait-list participants, symptom decline was especially pronounced among those with moderate symptoms at baseline as well as those not currently consulting a therapist. Completion (82%) and re-test reliability of the instruments (r = .72-.87) were good. The results of this trial suggest that online treatment can be beneficial for people with depression, particularly for those with moderate symptoms. Copyright © 2012 Elsevier Ltd.

    Since early 1950s fracture mechanics has brought significant impact on structural integrity assessment in a wide range of industries such as power, transportation, civil and petrochemical industries, especially in nuclear power plant industries. For the last two decades, significant efforts have been devoted in developing defect assessment procedures, from which various fitness-for-purpose or fitness-for-service codes have been developed. From another aspect, recent advances in IT (Information Technologies) bring rapid changes in various engineering fields. IT enables people to share information through network and thus provides concurrent working environment without limitations of working places. For this reason, a network system based on internet or intranet bas been appeared in various fields of business. Evaluating the integrity of structures is one of the most critical issues in nuclear industry. In order to evaluate the integrity of structures, a complicated and collaborative procedure is required including regular in-service inspection, fracture mechanics analysis, etc. And thus, experts in different fields have to cooperate to resolve the integrity problem. In this paper, an internet-based cooperative system for integrity evaluation system which adapts IT into a structural integrity evaluation procedure for reactor pressure vessel is introduced. The proposed system uses Virtual Reality (VR) technique, Virtual Network Computing (VNC) and agent programs. This system is able to support 3-dimensional virtual reality environment and to provide experts to cooperate by accessing related data through internet

    Full Text Available Major depression is among the most common and debilitating disorders worldwide, associated with large societal and individual costs. Effective treatments exist, but accessibility is scarce. Guided Internet-Based Cognitive Behavioral Therapy (guided iCBT is a promising approach to reach more people in need of help. In the present pilot study, we investigated the outcome of a guided iCBT program for mild and moderate depression when disseminated from Sweden to Norway. The guided iCBT intervention was implemented within a university-based outpatient clinic by six student therapists under supervision. Twenty-two participants with mild and moderate depression were included in the study. Large treatment effects were found for depressive symptoms, whereas small to medium effects were observed for anxiety symptoms. More than half (55% of the participants were classified as recovered at post-treatment and more than a third (41% at follow-up. No participants had a significant deterioration from pre- to post-treatment, but two reported a significant deterioration from post-treatment to 6-month follow-up. Benchmarking the present results against those reported in the four original Swedish studies, we found that the treatment effect in the Norwegian study was slightly higher at post-treatment and slightly lower at 6-month follow-up compared to the outcome in the Swedish studies. The results should be interpreted with caution, as our sample was small and had no control group.

    Factors influencing engagement with self-managed rehabilitation are not well understood, but evidence suggests they may change over time. Despite increasing digitalisation of self-managed interventions, little is known about the role of internet-based interventions in patients' experiences of self-directed rehabilitation. This longitudinal qualitative study investigated individuals' ongoing experiences of internet-guided, self-managed rehabilitation within the context of rehabilitation for dizziness. Eighteen adults aged fifty and over who experienced dizziness used the 'Balance Retraining' internet intervention for six weeks. Participants took part in semi-structured telephone interviews at two-week intervals to explore their experiences. Data were inductively thematically analysed. The internet intervention was reported to facilitate engagement with rehabilitation exercises, providing motivation to continue through symptom reduction and simple but helpful strategies. It was perceived as informative, reassuring, visually pleasing and easy to use. Barriers to engagement included practicalities, symptoms and doubts about exercise efficacy. Participants' perceptions did not always remain consistent over time. The internet intervention may be a feasible method of supporting self-managed vestibular rehabilitation. More generally, longitudinal findings suggest that appearance-related perceptions of online interventions may be especially important for initial engagement. Furthermore, intervention features targeting self-efficacy seem important in overcoming barriers to engagement.

    To evaluate the effect of an intelligent Internet-based information system upon optimising the management of patients diagnosed with type 2 diabetes mellitus (T2DM). In 2015, a T2DM information system was introduced to optimise the management of T2DM patients for 1 year in Fangzhuang community of Beijing, China. A total of 602 T2DM patients who were registered in the health service centre of Fangzhuang community were enrolled based on an isometric sampling technique. The data from 587 patients were used in the final analysis. The intervention effect was subsequently assessed by statistically comparing multiple parameters, such as the prevalence of glycaemic control, standard health management and annual outpatient consultation visits per person, before and after the implementation of the T2DM information system. In 2015, a total of 1668 T2DM patients were newly registered in Fangzhuang community. The glycaemic control rate was calculated as 37.65% in 2014 and significantly elevated up to 62.35% in 2015 ( p information system, the rate of standard health management was increased from 48.04% to 85.01% ( p information system optimised the management of T2DM patients in Fangzhuang community and decreased the outpatient numbers in both community and general hospitals, which played a positive role in assisting T2DM patients and their healthcare providers to better manage this chronic illness.

    This review article is an overview of the effectiveness of internet-based cognitive behavioral therapy (ICBT) in the treatment of psychiatric disorders. ICBT's effectiveness has been investigated in treating and managing conditions like depression, generalized anxiety disorder (GAD), panic disorder, obsessive compulsive disorder (OCD), post-traumatic stress disorder (PTSD), adjustment disorder, bipolar disorder, chronic pain, and phobias. ICBT's role in the treatment of medical conditions such as diabetes mellitus with comorbid psychiatric illnesses was also explored. Furthermore, this study elaborates on its cost-effectiveness and its impact in rural areas. We conducted a thorough literature search using PubMed and Google Scholar with no restrictions on the date. ICBT's role in treating and controlling psychiatric illnesses has been established in the literature. From the data compiled, we conclude that ICBT is useful in treating mental health and medical illnesses with psychiatric comorbidities. It has also been found to be cost-effective for patients and society. ICBT is a potential tool emerging with modern day technological advancements and is useful in rural and urban settings, across various languages and cultures, and on a global scale. Larger randomized control trials on its use in clinical practice and in reaching rural populations are bound to shed more light on the effectiveness of this tool along with spreading awareness among physician and patient communities.

    Full Text Available Abstract Background Cognitive behavior therapy (CBT is widely regarded as an effective treatment for obsessive compulsive disorder (OCD, but access to CBT therapists is limited. Internet-based CBT (ICBT with therapist support is a way to increase access to CBT but has not been developed or tested for OCD. The aim of this study was to evaluate ICBT for OCD. Method An open trial where patients (N = 23 received a 15-week ICBT program with therapist support consisting of psychoeducation, cognitive restructuring and exposure with response prevention. The primary outcome was the Yale-Brown Obsessive Compulsive Scale (Y-BOCS, which was assessed by a psychiatrist before and immediately after treatment. Secondary outcomes were self-rated measures of OCD symptoms, depressive symptoms, general functioning, anxiety and quality of life. All assessments were made at baseline and post-treatment. Results All participants completed the primary outcome measure at all assessment points. There were reductions in OCD symptoms with a large within-group effect size (Cohen's d = 1.56. At post-treatment, 61% of participants had a clinically significant improvement and 43% no longer fulfilled the diagnostic criteria of OCD. The treatment also resulted in statistically significant improvements in self-rated OCD symptoms, general functioning and depression. Conclusions ICBT with therapist support reduces OCD symptoms, depressive symptoms and improves general functioning. Randomized trials are needed to confirm the effectiveness of this new treatment format. Trial Registration ClinicalTrials.gov: NCT01348529

    Full Text Available Objective  To evaluate the effectiveness of internet-based cognitive behavioral therapy (ICBT for the treatment of insomnia by comparison of sleep parameters, degrees of anxiety and depression of the ICBT, with traditional face-to-face cognitive behavioral therapy (CBT and pharmacotherapy for insomnia. Methods  Seventy-nine cases meeting proposed DSM-5 criteria for insomnia disorder were randomly assigned to ICBT (n=27, CBT (n=26, and pharmacotherapy (n=26 group, and treated accordingly for 8 consecutive weeks. The sleep parameters, the levels of anxiety and depression in the 3 groups were compared and analyzed before, 4 weeks after and the termination of treatment. Results  Comparing to that of pre-treatment, the sleep parameters were significantly improved, anxiety and depression levels obviously decreased after treatment for 4 and 8 consecutive weeks, the differences were statistically significant (P0.05 was found in sleep parameters and anxiety level between ICBT group and CBT group. Conclusion  ICBT may display a slower effect on improving speed in falling asleep than the pharmacotherapy does, but the efficacy of ICBT is better than that of pharmacotherapy after treatment, and there is no significant difference compared to traditional face-to-face CBT.

    National dietary surveys are needed and difficult to conduct in China. The current study aims to develop and validate an internet-based diet questionnaire for Chinese (IDQC) to assess intakes in Northern China. We recruited 292 city residents by email and telephone in Harbin to obtain the IDQC and 3-day diet diaries. The food group and nutrient intakes from the IDQC were validated against those from the 3-day diet diaries. Paired sample t-tests were used to compare the methodological differences, and repeatability was estimated using Pearson's correlations. Cross-classification was used to calculate the percentage agreement in quartiles for all food groups and nutrients. Positive correlations were found between the IDQC and 3-day diet diaries for all food groups after energy adjustment (from 0.28 for seeds and nuts to 0.63 for dairy products). Positive correlations were observed for all nutrients between the IDQC and 3-day diet diaries, with correlations ranging from 0.37 for folic acid to 0.98 for iodine. The overall agreements for food groups and nutrients were above 69.2%, indicating satisfactory consistency between the IDQC and 3-day diet diaries. The IDQC can be used to estimate the food and nutrient intakes in a Northern China population for both clinical nutrition epidemiological and public health nutritional purposes. The questionnaire system IDQC (v1.0) is freely available at http://www.yyjy365.org/diet/.

    Information has become a commodity particularly important to industry, science, and politics. Information becomes critical because of its rapid change. The basis and the catalyst of this change in information are the information technologies now available, and the Internet with its varied contents. This makes the Internet a new market place which, although it is open, can quickly turn into an information maze because of its sheer volume. Also the nuclear industry must find its way through this maze. eNICE was created in order to build a bridge between the flood of information in the Internet and the information really needed in a specific case. eNICE (e stands for electronic, and NICE stands for Nuclear Information Compendium Europe), a living Internet-based nuclear compendium in the English language, is a unique combination of a broad spectrum of information and data about the use of nuclear power in Europe. The information and data contained in eNICE are interconnected with the World Wide Web in such a way that structured searching for nuclear information is possible quickly and efficiently. This avoids the difficulties sometimes encountered in searches in the Internet as a consequence of the unstructured volume of information. A monthly update of eNICE ensures that the data available are up to date and reliable. eNICE also offers direct access to the library used by RWE NUKEM for internal purposes. (orig.) [de

    Despite caring for large numbers of older adults, prehospital emergency medical services (EMS) providers receive minimal geriatrics-specific training while obtaining their certification. Studies have shown that they desire further training to improve their comfort level and knowledge in caring for older adults, but continuing education programs to address these needs must account for each EMS provider's specific needs, consider each provider's learning styles, and provide an engaging, interactive experience. A novel, Internet-based, video podcast-based geriatric continuing education program was developed and implemented for EMS providers, and their perceived value of the program was evaluated. They found this resource to be highly valuable and were strongly supportive of the modality and the specific training provided. Some reported technical challenges and the inability to engage in a discussion to clarify topics as barriers. It was felt that both of these barriers could be addressed through programmatic and technological revisions. This study demonstrates the proof of concept of video podcast training to address deficiencies in EMS education regarding the care of older adults, although further work is needed to demonstrate the educational effect of video podcasts on the knowledge and skills of trainees. © 2012, Copyright the Authors Journal compilation © 2012, The American Geriatrics Society.

    Patient care problems arise when health care consumers and professionals find health information on the Internet because that information is often inaccurate. To mitigate this problem, nurses can develop Web literacy and share that skill with health care consumers. This study evaluated a Web-literacy intervention for undergraduate nursing students to find reliable Web-based health information. A pre- and postsurvey queried undergraduate nursing students in an informatics course; the intervention comprised lecture, in-class practice, and assignments about health Web site evaluation tools. Data were analyzed using Wilcoxon and ANOVA signed-rank tests. Pre-intervention, 75.9% of participants reported using Web sites to obtain health information. Postintervention, 87.9% displayed confidence in using an evaluation tool. Both the ability to critique health Web sites (p = .005) and confidence in finding reliable Internet-based health information (p = .058) increased. Web-literacy education guides nursing students to find, evaluate, and use reliable Web sites, which improves their ability to deliver safer patient care. [J Nurs Educ. 2017;56(2):110-114.].

    2012-09-01

    Full Text Available Abstract Background In a recent exploratory randomised trial we found that a novel, internet-based psychoeducation programme for bipolar disorder (Beating Bipolar was relatively easy to deliver and had a modest effect on psychological quality of life. We sought to explore the experiences of participants with respect to feasibility, acceptability and impact of Beating Bipolar. Methods Participants were invited to take part in a semi-structured interview. Thematic analysis techniques were employed; to explore and describe participants’ experiences, the data were analysed for emerging themes which were identified and coded. Results The programme was feasible to deliver and acceptable to participants where they felt comfortable using a computer. It was found to impact upon insight into illness, health behaviour, personal routines and positive attitudes towards medication. Many participants regarded the programme as likely to be most beneficial for those recently diagnosed. Conclusions An online psychoeducation package for bipolar disorder, such as Beating Bipolar, is feasible and acceptable to patients, has a positive impact on self-management behaviours and may be particularly suited to early intervention. Alternative (non-internet formats should also be made available to patients.

  15. Diagnostic Procedures to Detect Chlamydia trachomatis Infections

    Directory of Open Access Journals (Sweden)

    2016-08-01

    Full Text Available The intracellular life style of chlamydia and the ability to cause persistent infections with low-grade replication requires tests with high analytical sensitivity to directly detect C. trachomatis (CT in medical samples. Nucleic acid amplification tests (NAATs are the most sensitive assays with a specificity similar to cell culture and are considered the method of choice for CT detection. In addition, NAATs can be performed on various clinical specimens that do not depend on specific transport and storage conditions, since NAATs do not require infectious bacteria. In the case of lower genital tract infections, first void urine and vaginal swabs are the recommended specimens for testing males and females, respectively. Infections of anorectal, oropharyngeal and ocular epithelia should also be tested by NAAT analysis of corresponding mucosal swabs. In particular, anorectal infections of men who have sex with men (MSM should include evaluation of lymphogranuloma venereum (LGV by identification of genotypes L1, L2 or L3. Detection of CT antigens by enzyme immunoassay (EIAs or rapid diagnostic tests (RDTs are unsuitable due to insufficient sensitivity and specificity. Recent PCR-based RDTs, however, are non-inferior to standard NAATs, and might be used at the point-of-care. Serology finds application in the diagnostic work-up of suspected chronic CT infection but is inappropriate to diagnose acute infections.

    Chlamydiosis is a common infectious disease of koalas (Phascolarctos cinereus), but Chlamydia spp. have not yet been demonstrated to cause pneumonia in these animals. A juvenile male koala died following an episode of respiratory disease. At necropsy examination, the lung tissue was consolidated. Microscopical lesions in the lung included pyogranulomatous bronchopneumonia, proliferation of bronchiolar and alveolar epithelium and interstitial fibrosis. Hyperplastic bronchiolar epithelial cells contained aggregates of small basophilic punctate organisms, which were confirmed as chlamydiae by transmission electron microscopy and immunohistochemistry. Real-time polymerase chain reaction identified these as Chlamydia pecorum. This report provides the best evidence to date of chlamydial infection causing pneumonia in a koala, and the first evidence that C. pecorum is capable of infecting the bronchiolar epithelium of the koala.

    Internet-based cognitive behavior therapy (CBT) has been shown to be a promising method to disseminate cognitive behavior therapy for social anxiety disorder (SAD). Several trials have demonstrated that Internet-based CBT can be effective for SAD in the shorter term. However, the long-term effects of Internet-based CBT for SAD are less well known. Our objective was to investigate the effect of Internet-based CBT for SAD 5 years after completed treatment. We conducted a 5-year follow-up study of 80 persons with SAD who had undergone Internet-based CBT. The assessment comprised a diagnostic interview and self-report questionnaires. The main outcome measure was the Liebowitz Social Anxiety Scale-Self-Report (LSAS-SR). Additional measures of social anxiety were the Social Interaction Anxiety Scale (SIAS) and the Social Phobia Scale (SPS). Attrition rates were low: 89% (71/80) of the participants completed the diagnostic interview and 80% (64/80) responded to the questionnaires. Mixed-effect models analysis showed a significant effect of time on the three social anxiety measures, LSAS-SR, SIAS, and SPS (F(3,98-102) = 16.05 - 29.20, P < .001) indicating improvement. From baseline to 5-year follow-up, participants' mean scores on the LSAS-SR were reduced from 71.3 (95% confidence interval [CI] 66.1-76.5) to 40.3 (95% CI 35.2 - 45.3). The effect sizes of the LSAS-SR were large (Cohen's d range 1.30 - 1.40, 95% CI 0.77 - 1.90). Improvements gained at the 1-year follow-up were sustained 5 years after completed treatment. Internet-based CBT for SAD is a treatment that can result in large and enduring effects.

    Full Text Available Abstract Background Engaging practicing physicians in educational strategies that reinforce guideline adoption and improve the quality of healthcare may be difficult. Push technologies such as email offer new opportunities to engage physicians in online educational reinforcing strategies. The objectives are to investigate 1 the effectiveness of email announcements in engaging recruited community-based primary care physicians in an online guideline reinforcement strategy designed to promote Chlamydia screening, 2 the characteristics of physicians who respond to email announcements, as well as 3 how quickly and when they respond to email announcements. Methods Over a 45-week period, 445 recruited physicians received up to 33 email contacts announcing and reminding them of an online women's health guideline reinforcing CME activity. Participation was defined as physician log-on at least once to the website. Data were analyzed to determine participation, to compare characteristics of participants with recruited physicians who did not participate, and to determine at what point and when participants logged on. Results Of 445 recruited physicians with accurate email addresses, 47.2% logged on and completed at least one module. There were no significant differences by age, race, or specialty between participants and non-participants. Female physicians, US medical graduates and MDs had higher participation rates than male physicians, international medical graduates and DOs. Physicians with higher baseline screening rates were significantly more likely to log on to the course. The first 10 emails were the most effective in engaging community-based physicians to complete the intervention. Physicians were more likely to log on in the afternoon and evening and on Monday or Thursday. Conclusions Email course reminders may enhance recruitment of physicians to interventions designed to reinforce guideline adoption; physicians' response to email reminders may

    How can science teachers become more familiar with emerging technology, excite their students and give students a taste of astronomy research? Astronomy teachers do not always have research experience, so it is difficult for them to convey to students how researchers use telescopes. The nature of astronomical observation (e.g., remote sites, expensive equipment, and odd hours) has been a barrier to providing teachers with insight into the process. Robotic telescopes (operated automatically with queued observing schedules) and remotely controlled telescopes (controlled by the user via the Internet) allow scientists to conduct observing sessions on research-grade telescopes half a world away. The same technology can now be harnessed by STEM educators to engage students and reinforce what is being taught in the classroom, as seen in some early research in elementary schools (McKinnon and Mainwaring 2000 and McKinnon and Geissinger 2002), and middle/high schools (Sadler et al. 2001, 2007 and Gehret et al. 2005). However, teachers need to be trained to use these resources. Responding to this need, graduate students and faculty at the University of Wyoming and CAPER Center for Astronomy & Physics Education Research are developing teacher professional development programs using Internet-based telescopes. We conducted an online course in the science education graduate program at the University of Wyoming. This course was designed to sample different types of Internet-based telescopes to evaluate them as resources for teacher professional development. The 10 participants were surveyed at the end of the course to assess their experiences with each activity. In addition, pre-test/post-test data were collected focusing specifically on one of the telescopes (Gershun, Berryhill and Slater 2012). Throughout the course, the participants learned to use a variety of robotic and remote telescopes including SLOOH Space Camera (www.slooh.com), Sky Titan Observatory (www

    Cognitive behavioral therapy (CBT) is an evidence-based method for treating specific phobias, but access to treatment is difficult, especially for children and adolescents with dental anxiety. Psychologist-guided Internet-based CBT (ICBT) may be an effective way of increasing accessibility while maintaining treatment effects. The aim of this study was to test the hypothesis that psychologist-guided ICBT improves school-aged children's and adolescents' ability to manage dental anxiety by (1) decreasing avoidance and affecting the phobia diagnosis and (2) decreasing the dental fear and increasing the target groups' self-efficacy. The study also aimed to examine the feasibility and acceptability of this novel treatment. This was an open, uncontrolled trial with assessments at baseline, posttreatment, and the 1-year follow-up. The study enrolled and treated 18 participants. The primary outcome was level of avoidance behaviors, as measured by the picture-guided behavioral avoidance test (PG-BAT). The secondary outcome was a diagnostic evaluation with the parents conducted by a psychologist. The specific phobia section of the structured interview Kiddie-Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime (K-SADS-PL) was used. Other outcome measures included level of dental anxiety and self-efficacy. The ICBT, which employed exposure therapy, comprised 12 modules of texts, animations, dentistry-related video clips, and an exercise package (including dental instruments). Participants accessed the treatment through an Internet-based treatment platform and received Web-based guidance from a psychologist. Treatment also included training at dental clinics. Feasibility and acceptability were assessed by measures of engagement, adherence, compliance, completed measures, patient and parent satisfaction scale, and staff acceptability. The level of avoidance (according to the primary outcome measure PG-BAT) and dental anxiety decreased

    period, albeit without therapist contact. Results The current study is believed to result in three important findings. First, a CBT intervention is assumed to be beneficial for people suffering from problems caused by procrastination. Second, the degree of therapist contact will have a positive effect on treatment outcome as procrastination can be partially explained as a self-regulatory failure. Third, an Internet based CBT intervention is presumed to be an effective way to administer treatment for procrastination, which is considered highly important, as the availability of adequate care is limited. The current study is therefore believed to render significant knowledge on the treatment of procrastination, as well as providing support for the use of Internet based CBT for difficulties due to delayed tasks and commitments. Conclusions To our knowledge, the current study is the first clinical trial to examine the effects of CBT for procrastination, and is assumed to render significant knowledge on the treatment of procrastination, as well as investigating whether it can be delivered via the Internet.

    Human rights advocates play a critical role in promoting respect for human rights world-wide, and engage in a broad range of strategies, including documentation of rights violations, monitoring, press work and report-writing, advocacy, and litigation. However, little is known about the impact of human rights work on the mental health of human rights advocates. This study examined the mental health profile of human rights advocates and risk factors associated with their psychological functioning. 346 individuals currently or previously working in the field of human rights completed an internet-based survey regarding trauma exposure, depression, posttraumatic stress disorder (PTSD), resilience and occupational burnout. PTSD was measured with the Posttraumatic Stress Disorder Checklist-Civilian Version (PCL-C) and depression was measured with the Patient History Questionnaire-9 (PHQ-9). These findings revealed that among human rights advocates that completed the survey, 19.4% met criteria for PTSD, 18.8% met criteria for subthreshold PTSD, and 14.7% met criteria for depression. Multiple linear regressions revealed that after controlling for symptoms of depression, PTSD symptom severity was predicted by human rights-related trauma exposure, perfectionism and negative self-appraisals about human rights work. In addition, after controlling for symptoms of PTSD, depressive symptoms were predicted by perfectionism and lower levels of self-efficacy. Survey responses also suggested high levels of resilience: 43% of responders reported minimal symptoms of PTSD. Although survey responses suggest that many human rights workers are resilient, they also suggest that human rights work is associated with elevated rates of PTSD and depression. The field of human rights would benefit from further empirical research, as well as additional education and training programs in the workplace about enhancing resilience in the context of human rights work.

  4. An Internet-Based Real-Time Audiovisual Link for Dual MEG Recordings.

    Full Text Available Most neuroimaging studies of human social cognition have focused on brain activity of single subjects. More recently, "two-person neuroimaging" has been introduced, with simultaneous recordings of brain signals from two subjects involved in social interaction. These simultaneous "hyperscanning" recordings have already been carried out with a spectrum of neuroimaging modalities, such as functional magnetic resonance imaging (fMRI, electroencephalography (EEG, and functional near-infrared spectroscopy (fNIRS.We have recently developed a setup for simultaneous magnetoencephalographic (MEG recordings of two subjects that communicate in real time over an audio link between two geographically separated MEG laboratories. Here we present an extended version of the setup, where we have added a video connection and replaced the telephone-landline-based link with an Internet connection. Our setup enabled transmission of video and audio streams between the sites with a one-way communication latency of about 130 ms. Our software that allows reproducing the setup is publicly available.We demonstrate that the audiovisual Internet-based link can mediate real-time interaction between two subjects who try to mirror each others' hand movements that they can see via the video link. All the nine pairs were able to synchronize their behavior. In addition to the video, we captured the subjects' movements with accelerometers attached to their index fingers; we determined from these signals that the average synchronization accuracy was 215 ms. In one subject pair we demonstrate inter-subject coherence patterns of the MEG signals that peak over the sensorimotor areas contralateral to the hand used in the task.

    Translational research requires taking basic science observations and developing them into clinically useful tests and therapeutics. We have developed a process to develop molecular biomarkers for diagnosis and prognosis by integrating tissue microarray (TMA) technology and an internet-database tool, Profiler. TMA technology allows investigators to study hundreds of patient samples on a single glass slide resulting in the conservation of tissue and the reduction in inter-experimental variability. The Profiler system allows investigator to reliably track, store, and evaluate TMA experiments. Here within we describe the process that has evolved through an empirical basis over the past 5 years at two academic institutions. The generic design of this system makes it compatible with multiple organ system (e.g., prostate, breast, lung, renal, and hematopoietic system,). Studies and folders are restricted to authorized users as required. Over the past 5 years, investigators at 2 academic institutions have scanned 656 TMA experiments and collected 63,311 digital images of these tissue samples. 68 pathologists from 12 major user groups have accessed the system. Two groups directly link clinical data from over 500 patients for immediate access and the remaining groups choose to maintain clinical and pathology data on separate systems. Profiler currently has 170 K data points such as staining intensity, tumor grade, and nuclear size. Due to the relational database structure, analysis can be easily performed on single or multiple TMA experimental results. The TMA module of Profiler can maintain images acquired from multiple systems. We have developed a robust process to develop molecular biomarkers using TMA technology and an internet-based database system to track all steps of this process. This system is extendable to other types of molecular data as separate modules and is freely available to academic institutions for licensing.

    Prior research has shown that the Sadness Program, a technician-assisted Internet-based cognitive behavioral therapy (iCBT) intervention developed in Australia, is effective for treating major depressive disorder (MDD). The current study aimed to expand this work by adapting the protocol for an American population and testing the Sadness Program with an attention control group. In this parallel-group, randomized controlled trial, adult MDD participants (18-45 years) were randomized to a 10-week period of iCBT (n = 37) or monitored attention control (MAC; n = 40). Participants in the iCBT group completed six online therapy lessons, which included access to content summaries and homework assignments. During the 10-week trial, iCBT and MAC participants logged into the web-based system six times to complete self-report symptom scales, and a nonclinician technician contacted participants weekly to provide encouragement and support. The primary outcome was the Hamilton Rating Scale for Depression (HRSD), and the secondary outcomes were the Patient Health Questionnaire-9 and Kessler-10. Intent-to-treat analyses revealed significantly greater reductions in depressive symptoms in iCBT compared with MAC participants, using both the self-report measures and the clinician-rated HRSD (d = -0.80). Importantly, iCBT participants also showed significantly higher rates of clinical response and remission. Exploratory analyses did not support illness severity as a moderator of treatment outcome. The Sadness Program led to significant reductions in depression and distress symptoms. With its potential to be delivered in a scalable, cost-efficient manner, iCBT is a promising strategy to enhance access to effective care. © 2016 Wiley Periodicals, Inc.

    Evolving information technology has raised the possibility of new methods of data collection in multiple sclerosis (MS) research. An anonymous, self-report, Internet-based survey was developed, which asked people with MS their opinion on how various extrinsic factors affected their condition. From September 2001 to July 2002, a total of 2529 people completed the questionnaire. The demographic and clinical profiles of the anonymous respondents indicated that most were likely to have MS. Common factors reported as beneficial were cannabis, cold baths, meditation and dietary factors. Common adverse factors reported were high stress, exposure to high temperatures and viral infections. There was an increasing report of high temperatures as being adverse with increasing respondent age (test for trend, P < 0.001). The adverse report of high temperatures correlated significantly with the report of strong sunlight apparently making MS worse (r = 0.35, P < 0.0001). In Australia, high temperatures were more likely to be reported as adverse in warmer, lower latitude regions. The association between strong sunlight as adverse and age or region did not persist after adjustment for high temperatures. Thus, this apparent adverse factor appeared to relate to solar heat, not solar light. People with MS may risk vitamin D deficiency because of sun avoidance due to heat-related fatigue or intolerance. This is of clinical significance not only for bone health but because vitamin D may have beneficial immunomodulatory properties. The present study provides new information from people with MS on factors that may influence symptoms or clinical course. This information will now be used in the design of formal epidemiological cohort studies.

    AZ Technology has been working with NASA MSFC (Marshall Space Flight Center) to find ways to make it easier for remote experimenters (RPI's) to monitor their International Space Station (ISS) payloads in real-time from anywhere using standard/familiar devices. That effort resulted in a product called 'EZStream' which is in use on several ISS-related projects. Although the initial implementation is geared toward ISS, the architecture and lessons learned are applicable to other space-related programs. This paper begins with a brief history on why Internet-based real-time data is important and where EZStream or products like it fit in the flow of data from orbit to experimenter/researcher. A high-level architecture is then presented along with explanations of the components used. A combination of commercial-off-the-shelf (COTS), Open Source, and custom components are discussed. The use of standard protocols is shown along with some details on how data flows between server and client. Some examples are presented to illustrate how a system like EZStream can be used in real world applications and how care was taken to make the end-user experience as painless as possible. A system such as EZStream has potential in the commercial (non-ISS) arena and some possibilities are presented. During the development and fielding of EZStream, a lot was learned. Good and not so good decisions were made. Some of the major lessons learned will be shared. The development of EZStream is continuing and the future of EZStream will be discussed to shed some light over the technological horizon.

    The objective of this study was to assess the source, quality, accuracy, and completeness of Internet-based information for shoulder arthritis. A web search was performed using three common Internet search engines and the top 50 sites from each search were analyzed. Information sources were categorized into academic, commercial, non-profit, and physician sites. Information quality was measured using the Health On the Net (HON) Foundation principles, content accuracy by counting factual errors and completeness using a custom template. After removal of duplicates and sites that did not provide an overview of shoulder arthritis, 49 websites remained for analysis. The majority of sites were from commercial (n = 16, 33%) and physician (n = 16, 33%) sources. An additional 12 sites (24%) were from an academic institution and five sites (10%) were from a non-profit organization. Commercial sites had the highest number of errors, with a five-fold likelihood of containing an error compared to an academic site. Non-profit sites had the highest HON scores, with an average of 9.6 points on a 16-point scale. The completeness score was highest for academic sites, with an average score of 19.2 ± 6.7 (maximum score of 49 points); other information sources had lower scores (commercial, 15.2 ± 2.9; non-profit, 18.7 ± 6.8; physician, 16.6 ± 6.3). Patient information on the Internet regarding shoulder arthritis is of mixed accuracy, quality, and completeness. Surgeons should actively direct patients to higher-quality Internet sources.

  10. Internet-based wide area measurement applications in deregulated power systems

    Khatib, Abdel-Rahman Amin

    Since the deregulation of power systems was started in 1989 in the UK, many countries have been motivated to undergo deregulation. The United State started deregulation in the energy sector in California back in 1996. Since that time many other states have also started the deregulation procedures in different utilities. Most of the deregulation market in the United States now is in the wholesale market area, however, the retail market is still undergoing changes. Deregulation has many impacts on power system network operation and control. The number of power transactions among the utilities has increased and many Independent Power Producers (IPPs) now have a rich market for competition especially in the green power market. The Federal Energy Regulatory Commission (FERC) called upon utilities to develop the Regional Transmission Organization (RTO). The RTO is a step toward the national transmission grid. RTO is an independent entity that will operate the transmission system in a large region. The main goal of forming RTOs is to increase the operation efficiency of the power network under the impact of the deregulated market. The objective of this work is to study Internet based Wide Area Information Sharing (WAIS) applications in the deregulated power system. The study is the first step toward building a national transmission grid picture using information sharing among utilities. Two main topics are covered as applications for the WAIS in the deregulated power system, state estimation and Total Transfer Capability (TTC) calculations. As a first step for building this national transmission grid picture, WAIS and the level of information sharing of the state estimation calculations have been discussed. WAIS impacts to the TTC calculations are also covered. A new technique to update the TTC using on line measurements based on WAIS created by sharing state estimation is presented.

    To obtain information on the types of Australian horses, how they are kept and their activities. An invitation to participate in an opt-in, internet-based survey was sent to 7000 people who had registered an email address to receive information from the Australian Horse Industry Council Inc. There were 3377 (48%) useable responses from owners of 26,548 horses. Most horses were kept on small properties (usually 2-8 ha) in paddocks in rural areas of Queensland, New South Wales and Victoria. Most horses were female or geldings and the most common of 54 different activities was breeding. Owners reported 19,291 horses were used in different activities and 6037 (23%) horses were not kept for any stated purpose or activity. Owners used an average of 1.95 horses in 2.9 different types of activities. The most common of the 43 breeds were Thoroughbred, Australian Stock Horse and Australian Quarter Horse. Only 1% of the total numbers of Thoroughbreds and Standardbreds in this survey were used in horse racing, indicating there is a demand for these breeds in non-racing activities. Microchip was the most favoured method of horse identification and 36% favoured compulsory registration of horses. Most respondents reported owning some other animal species. There is a wide variation in horse breeds used in different activities by Australian horse owners. There are regional differences in various management systems. There needs to be considerable improvement in the collection and recording of information to improve the validity and reliability of horse industry data. © 2016 Australian Veterinary Association.

    Even though there is an increasing number of studies on the efficacy of Internet-based interventions (IBI) for depression, experimental trials on the benefits of added guidance by clinicians are scarce and inconsistent. This study compared the efficacy of semistandardized feedback provided by psychologists with fully standardized feedback in IBI. Participants with mild-to-moderate depression (n = 1,089, 66% female) from the client pool of a health insurance company participated in a cognitive-behavioral IBI targeting depression over 6 weeks. Individuals were randomized to weekly semistandardized e-mail feedback from psychologists (individual counseling; IC) or to automated, standardized feedback where a psychologist could be contacted on demand (CoD). The contents and tasks were identical across conditions. The primary outcome was depression; secondary outcomes included anxiety, rumination, and well-being. Outcomes were assessed before and after the intervention and 3, 6, and 12 months later. Changes in outcomes were evaluated using latent change score modeling. Both interventions yielded large pre-post effects on depression (Beck Depression Inventory-II: dIC = 1.53, dCoD = 1.37; Patient Health Questionnaire-9: dIC = 1.20, dCoD = 1.04), as well as significant improvements of all other outcome measures. The effects remained significant after 3, 6, and 12 months. The groups differed with regard to attrition (IC: 17.3%, CoD: 25.8%, p = 0.001). Between-group effects were statistically nonsignificant across outcomes and measurement occasions. Adding semistandardized guidance in IBI for depression did not prove to be more effective than fully standardized feedback on primary and secondary outcomes, but it had positive effects on attrition. © 2018 S.

    Full Text Available Dengue is a common and growing problem worldwide, with an estimated 70-140 million cases per year. Traditional, healthcare-based, government-implemented dengue surveillance is resource intensive and slow. As global Internet use has increased, novel, Internet-based disease monitoring tools have emerged. Google Dengue Trends (GDT uses near real-time search query data to create an index of dengue incidence that is a linear proxy for traditional surveillance. Studies have shown that GDT correlates highly with dengue incidence in multiple countries on a large spatial scale. This study addresses the heterogeneity of GDT at smaller spatial scales, assessing its accuracy at the state-level in Mexico and identifying factors that are associated with its accuracy. We used Pearson correlation to estimate the association between GDT and traditional dengue surveillance data for Mexico at the national level and for 17 Mexican states. Nationally, GDT captured approximately 83% of the variability in reported cases over the 9 study years. The correlation between GDT and reported cases varied from state to state, capturing anywhere from 1% of the variability in Baja California to 88% in Chiapas, with higher accuracy in states with higher dengue average annual incidence. A model including annual average maximum temperature, precipitation, and their interaction accounted for 81% of the variability in GDT accuracy between states. This climate model was the best indicator of GDT accuracy, suggesting that GDT works best in areas with intense transmission, particularly where local climate is well suited for transmission. Internet accessibility (average ∼ 36% did not appear to affect GDT accuracy. While GDT seems to be a less robust indicator of local transmission in areas of low incidence and unfavorable climate, it may indicate cases among travelers in those areas. Identifying the strengths and limitations of novel surveillance is critical for these types of data to

    Lifetime exposure to physical activity is an important construct for evaluating associations between physical activity and disease outcomes, given the long induction periods in many chronic diseases. The authors' objective in this study was to evaluate the measurement properties of the Lifetime Physical Activity Questionnaire (L-PAQ), a novel Internet-based, self-administered instrument measuring lifetime physical activity, among Canadian men and women in 2005-2006. Reliability was examined using a test-retest study. Validity was examined in a 2-part study consisting of 1) comparisons with previously validated instruments measuring similar constructs, the Lifetime Total Physical Activity Questionnaire (LT-PAQ) and the Chasan-Taber Physical Activity Questionnaire (CT-PAQ), and 2) a priori hypothesis tests of constructs measured by the L-PAQ. The L-PAQ demonstrated good reliability, with intraclass correlation coefficients ranging from 0.67 (household activity) to 0.89 (sports/recreation). Comparison between the L-PAQ and the LT-PAQ resulted in Spearman correlation coefficients ranging from 0.41 (total activity) to 0.71 (household activity); comparison between the L-PAQ and the CT-PAQ yielded coefficients of 0.58 (sports/recreation), 0.56 (household activity), and 0.50 (total activity). L-PAQ validity was further supported by observed relations between the L-PAQ and sociodemographic variables, consistent with a priori hypotheses. Overall, the L-PAQ is a useful instrument for assessing multiple domains of lifetime physical activity with acceptable reliability and validity.

    Various professional societies, clinical practices, hospitals, and health care-related Web sites provide Internet-based patient education material (IPEMs) to the general public. However, this information may be written above the 6th-grade reading level recommended by the US Department of Health and Human Services. The purpose of this study is to assess the readability of facial fracture (FF)-related IPEMs and compare readability levels of IPEMs provided by four sources: professional societies, clinical practices, hospitals, and miscellaneous sources. Analysis of IPEMs on FFs available on Google.com. The readability of 41 FF-related IPEMs was assessed with four readability indices: Flesch-Kincaid Grade Level (FKGL), Flesch Reading Ease Score (FRES), Simple Measure of Gobbledygook (SMOG), and Gunning Frequency of Gobbledygook (Gunning FOG). Averages were evaluated against national recommendations and between each source using analysis of variance and t tests. Only 4.9% of IPEMs were written at or below the 6th-grade reading level, based on FKGL. The mean readability scores were: FRES 54.10, FKGL 9.89, SMOG 12.73, and Gunning FOG 12.98, translating into FF-related IPEMs being written at a "difficult" writing level, which is above the level of reading understanding of the average American adult. IPEMs related to FFs are written above the recommended 6th-grade reading level. Consequently, this information would be difficult to understand by the average US patient.

    The US Department of Health and Human Services (USDHHS) recommends that Internet-based patient education materials (IPEMs) be written below the sixth-grade reading level to target the average American adult. This study was designed to determine the readability of IPEMs regarding mammography for breast cancer screening. Three-hundred mammography-related Web sites were reviewed for IPEMs. Forty-two IPEMs that met the Health on the Net Foundation Code of Conduct were assessed for readability level with four readability indices that use existing algorithms based on word and sentence length to quantitatively analyze Internet sources for language intricacy including the following: Flesch-Kincaid Grade Level (FKGL), Flesch Reading Ease Score (FRES), Simple Measure of Gobbledygook (SMOG), and Gunning Frequency of Gobbledygook (Gunning FOG; GFOG). Results were compared to national recommendations, and intergroup analysis was performed. No IPEMs (0%) regarding mammography were written at or below the sixth-grade reading level, based on FKGL. The mean readability scores were as follows: FRES, 49.04 ± 10.62; FKGL, 10.71 ± 2.01; SMOG, 13.33 ± 1.67; and Gunning FOG, 14.32 ± 2.18. These scores indicate that the readability of mammography IPEMs is written at a "difficult" level, significantly above the recommended sixth-grade reading level (P < .05) determined by the USDHHS. IPEMs related to mammography are written well above the recommended sixth-grade level and likely reflect other IPEMs in diagnostic radiology. Copyright © 2015 AUR. Published by Elsevier Inc.

    The increase within the energy and effect consumption in Norway, parallel with a small development of new power production has resulted in an increased focus on the end user flexibility. An efficient utilisation of the end user flexibility assumes that the market mechanisms are adapted/developed so that the user has economical incentives for reducing the consumption in periods with energy and effect shortage. Furthermore the technological solutions within the information and communication technology (ICT) open new possibilities for acquiring energy and effect reducing potentials at the end users. The Internet is an universal communication channel which opens new possibilities for communication between the power market and the end users. The unique properties of the internet particularly the easy access and low costs for upgrading and maintenance, makes a considerable potential for the use of new products and services which will increase the flexibility in the use of energy and effect. The report presents a survey of existing products and services which are offered on the Internet in the power sector. The report emphasises particularly on a comparison of these solutions regarding purpose, functionality, user friendliness and limitations of these products. The appendix includes a glossary of works and expressions which is related to the ICT. This report is published as a part of a sub project ''Internet based services for customers with current communication'' in a research project. ''Consumer flexibility and efficient use of ICT''. The project is financed by the Norges Forskningsraad, EBL Kompetanse AS and others and is carried out at the SINTEF Energiforskning AS. This project has been started from results and experiences from earlier projects as ''End user market'' and ''Information and communication systems for the energy sector''

  18. Mental Health Functioning in the Human Rights Field: Findings from an International Internet-Based Survey.

    Full Text Available Human rights advocates play a critical role in promoting respect for human rights world-wide, and engage in a broad range of strategies, including documentation of rights violations, monitoring, press work and report-writing, advocacy, and litigation. However, little is known about the impact of human rights work on the mental health of human rights advocates. This study examined the mental health profile of human rights advocates and risk factors associated with their psychological functioning. 346 individuals currently or previously working in the field of human rights completed an internet-based survey regarding trauma exposure, depression, posttraumatic stress disorder (PTSD, resilience and occupational burnout. PTSD was measured with the Posttraumatic Stress Disorder Checklist-Civilian Version (PCL-C and depression was measured with the Patient History Questionnaire-9 (PHQ-9. These findings revealed that among human rights advocates that completed the survey, 19.4% met criteria for PTSD, 18.8% met criteria for subthreshold PTSD, and 14.7% met criteria for depression. Multiple linear regressions revealed that after controlling for symptoms of depression, PTSD symptom severity was predicted by human rights-related trauma exposure, perfectionism and negative self-appraisals about human rights work. In addition, after controlling for symptoms of PTSD, depressive symptoms were predicted by perfectionism and lower levels of self-efficacy. Survey responses also suggested high levels of resilience: 43% of responders reported minimal symptoms of PTSD. Although survey responses suggest that many human rights workers are resilient, they also suggest that human rights work is associated with elevated rates of PTSD and depression. The field of human rights would benefit from further empirical research, as well as additional education and training programs in the workplace about enhancing resilience in the context of human rights work.

    To evaluate risk factors for gastric dilatation-volvulus (GDV) in a large number of privately owned dogs across a wide geographic area. Internet-based, cross-sectional study. 2,551 privately owned dogs. A questionnaire addressed dog-specific, management, environmental, and personality-associated risk factors for GDV in dogs. Respondents were recruited through the posting of the electronic link to the questionnaire on websites for dog owners; the information was also disseminated at meetings of dog owners and via newsletters, e-mail lists for dog owners and breeders, owner-oriented dog publications, and e-mails forwarded by participants. Descriptive statistics and logistic regression analysis were performed. Factors significantly associated with an increased risk of GDV were being fed dry kibble, anxiety, residence in the United Kingdom, being born in the 1990s, being a family pet, and spending at least 5 hours a day with the owner. Factors associated with a decreased risk of GDV were playing with other dogs and running the fence after meals, fish and egg dietary supplements, and spending equal time indoors and outdoors. A significant interaction between sex and neuter status was observed, with sexually intact females having the highest risk for GDV. In dogs with a high risk of GDV, regular moderate daily and postprandial activity appeared to be beneficial. Feeding only commercial dry dog food may not be the best choice for dogs at risk; however, supplements with fish or eggs may reduced this risk. The effect of neuter status on GDV risk requires further characterization.

  20. Experiences of undergoing Internet-based cognitive behavior therapy for procrastination: A qualitative study

    Full Text Available Internet interventions constitute a promising and cost-effective treatment alternative for a wide range of psychiatric disorders and somatic conditions. Several clinical trials have provided evidence for its efficacy and effectiveness, and recent research also indicate that it can be helpful in the treatment of conditions that are debilitating, but do not necessarily warrant more immediate care, for instance, procrastination, a self-regulatory failure that is associated with decreased well-being and mental health. However, providing treatment interventions for procrastination via the Internet is a novel approach, making it unclear how the participants themselves perceive their experiences. The current study thus investigated participants' own apprehension of undergoing Internet-based cognitive behavior therapy for procrastination by distributing open-ended questions at the post-treatment assessment, for instance, “What did you think about the readability of the texts”, “How valuable do you believe that this treatment has been for you?”, and “The thing that I am most displeased with (and how it could be improved is …”. In total, 75 participants (50% responded, and the material was examined using thematic analysis. The results indicate that there exist both positive and negative aspects of the treatment program. Many participants increased their self-efficacy and were able to gain momentum on many tasks and assignments that had been deferred in their everyday life. Meanwhile, several participants lacked motivation to complete the exercises, had too many conflicting commitments, and were unable to keep up with the tight treatment schedule. Hence, the results suggest that Internet interventions for procrastination could profit from individual tailoring, shorter and more manageable modules, and that the content need to be adapted to the reading comprehension and motivational level of the participant.

    As much as 10-15% of new mothers experience depression postpartum. An Internet-based intervention (Mamma Mia) was developed with the primary aims of preventing depressive symptoms and enhancing subjective well-being among pregnant and postpartum women. A secondary aim of Mamma Mia was to ease the transition of becoming a mother by providing knowledge, techniques, and support during pregnancy and after birth. The aim of the paper is to provide a systematic and comprehensive description of the intervention rationale and the development of Mamma Mia. For this purpose, we used the intervention mapping (IM) protocol as descriptive tool, which consists of the following 6 steps: (1) a needs assessment, (2) definition of change objectives, (3) selection of theoretical methods and practical strategies, (4) development of program components, (5) planning adoption and implementation, and (6) planning evaluation. Mamma Mia is a fully automated Internet intervention available for computers, tablets, and smartphones, intended for individual use by the mother. It starts in gestational week 18-24 and lasts up to when the baby becomes 6 months old. This intervention applies a tunneled design to guide the woman through the program in a step-by-step fashion in accordance with the psychological preparations of becoming a mother. The intervention is delivered by email and interactive websites, combining text, pictures, prerecorded audio files, and user input. It targets risk and protective factors for postpartum depression such as prepartum and postpartum attachment, couple satisfaction, social support, and subjective well-being, as identified in the needs assessment. The plan is to implement Mamma Mia directly to users and as part of ordinary services at well-baby clinics, and to evaluate the effectiveness of Mamma Mia in a randomized controlled trial and assess users' experiences with the program. The IM of Mamma Mia has made clear the rationale for the intervention, and linked

    Chlamydia trachomatis (CT) is the most commonly reported sexually transmitted infection (STI) in the US and timely, correct treatment can reduce CT transmission and sequelae. Emergency departments (ED) are an important location for diagnosing STIs. This study compared recommended treatment of CT in EDs to treatment in physician offices. Five years of data (2006-2010) were analyzed from the National Ambulatory Medical Care Survey, and the National Hospital Ambulatory Medical Care Surveys (NHAMCS), including the Outpatient survey (NHAMCS-OPD) and Emergency Department survey (NHAMCS-ED). All visits with a CT diagnosis and those with a diagnosis of unspecified venereal disease were selected for analysis. Differences in receipt of recommended treatments were compared between visits to physician offices and emergency departments using Chi square tests and logistic regression models. During the 5 year period, approximately 3.2 million ambulatory care visits had diagnosed CT or an unspecified venereal disease. A greater proportion of visits to EDs received the recommended treatment for CT compared to visits to physician offices (66.1 vs. 44.9 %, p < .01). When controlling for patients' age, sex and race/ethnicity, those presenting to the ED with CT were more likely to receive the recommended antibiotic treatment than patients presenting to a physician's office (OR 2.16; 95 % CI 1.04-4.48). This effect was attenuated when further controlling for patients' expected source of payment. These analyses demonstrate differences in the treatment of CT by ambulatory care setting as well as opportunities for increasing use of recommended treatments for diagnosed cases of this important STI.

    Executive Summary Objective The objective of this Medical Advisory Secretariat (MAS) report was to conduct a systematic review of the available published evidence on the safety, effectiveness, and cost-effectiveness of Internet-based device-assisted remote monitoring systems (RMSs) for therapeutic cardiac implantable electronic devices (CIEDs) such as pacemakers (PMs), implantable cardioverter-defibrillators (ICDs), and cardiac resynchronization therapy (CRT) devices. The MAS evidence-based review was performed to support public financing decisions. Clinical Need: Condition and Target Population Sudden cardiac death (SCD) is a major cause of fatalities in developed countries. In the United States almost half a million people die of SCD annually, resulting in more deaths than stroke, lung cancer, breast cancer, and AIDS combined. In Canada each year more than 40,000 people die from a cardiovascular related cause; approximately half of these deaths are attributable to SCD. Most cases of SCD occur in the general population typically in those without a known history of heart disease. Most SCDs are caused by cardiac arrhythmia, an abnormal heart rhythm caused by malfunctions of the heart’s electrical system. Up to half of patients with significant heart failure (HF) also have advanced conduction abnormalities. Cardiac arrhythmias are managed by a variety of drugs, ablative procedures, and therapeutic CIEDs. The range of CIEDs includes pacemakers (PMs), implantable cardioverter-defibrillators (ICDs), and cardiac resynchronization therapy (CRT) devices. Bradycardia is the main indication for PMs and individuals at high risk for SCD are often treated by ICDs. Heart failure (HF) is also a significant health problem and is the most frequent cause of hospitalization in those over 65 years of age. Patients with moderate to severe HF may also have cardiac arrhythmias, although the cause may be related more to heart pump or haemodynamic failure. The presence of HF, however

    Certain risk factors associated with overweight and obesity may lead to reduced productivity in the workforce (i.e., increased absenteeism and presenteeism). Participants in a large, Internet-based worksite weight loss intervention, who were present at follow-up (N = 1,030), completed a self-reported productivity measure (World Health Organization’s Health and Work Performance Questionnaire) at baseline and postintervention. Twenty-two percent of the participants lost a clinically meaningful amount of weight (≥5% weight loss). There were no statistically significant (p absenteeism or for absolute or relative presenteeism. Within a modestly successful Internet-based, worksite weight loss intervention, weight loss did not improve self-reported absenteeism or presenteeism. Further studies are needed to explore the sensitivity of the World Health Organization’s Health and Work Performance Questionnaire and the long-term effects of weight loss on productivity.

    2013-01-01

    Chlamydia trachomatis replicates in a parasitophorous membrane-bound compartment called an inclusion. The inclusions corrupt host vesicle trafficking networks to avoid the degradative endolysosomal pathway but promote fusion with each other in order to sustain higher bacterial loads in a process known as homotypic fusion. The Chlamydia protein IncA (Inclusion protein A) appears to play central roles in both these processes as it participates to homotypic fusion and inhibits endocytic SNARE-mediated membrane fusion. How IncA selectively inhibits or activates membrane fusion remains poorly understood. In this study, we analyzed the spatial and molecular determinants of IncA's fusogenic and inhibitory functions. Using a cell-free membrane fusion assay, we found that inhibition of SNARE-mediated fusion requires IncA to be on the same membrane as the endocytic SNARE proteins. IncA displays two coiled-coil domains showing high homology with SNARE proteins. Domain swap and deletion experiments revealed that although both these domains are capable of independently inhibiting SNARE-mediated fusion, these two coiled-coil domains cooperate in mediating IncA multimerization and homotypic membrane interaction. Our results support the hypothesis that Chlamydia employs SNARE-like virulence factors that positively and negatively affect membrane fusion and promote infection.

    Balance disorders are common in multiple sclerosis. Aim of the study is to investigate the effectiveness of an Internet-based home training program (e-Training) to improve balance in patients with multiple sclerosis. A randomized, controlled study. Academic teaching hospital in cooperation with the therapeutic riding center Gut Üttingshof, Bad Mergentheim. Eighteen multiple sclerosis patients (mean EDSS 3,5) took part in the trial. Outcome of patients using e-Training (N.=9) was compared to the outcome of patients receiving hippotherapy (N.=9), which can be considered as an advanced concept for the improvement of balance and postural control in multiple sclerosis. After simple random allocation patients received hippotherapy or Internet-based home training (balance, postural control and strength training) twice a week for 12 weeks. Assessments were done before and after the intervention and included static and dynamic balance (primary outcome). Isometric muscle strength of the knee and trunk extension/flexion (dynamometer), walking capacity, fatigue and quality of life served as secondary outcome parameters. Both intervention groups showed comparable and highly significant improvement in static and dynamic balance capacity, no difference was seen between the both intervention groups. However looking at fatigue and quality of life only the group receiving hippotherapy improved significantly. Since e-Training shows even comparable effects to hippotherapy to improve balance, we believe that the established Internet-based home training program, specialized on balance and postural control training, is feasible for a balance and strength training in persons with multiple sclerosis. We demonstrated that Internet-based home training is possible in patients with multiple sclerosis.

    The internet is gaining popularity as a means of delivering employee-based cardiovascular (CV) wellness interventions though little is known about the cardiovascular health outcomes of these programs. In this review, we examined the effectiveness of internet-based employee cardiovascular wellness and prevention programs. We conducted a systematic review by searching PubMed, Web of Science and Cochrane library for all published studies on internet-based programs aimed at improving CV health among employees up to November 2012. We grouped the outcomes according to the American Heart Association (AHA) indicators of cardiovascular wellbeing--weight, BP, lipids, smoking, physical activity, diet, and blood glucose. A total of 18 randomized trials and 11 follow-up studies met our inclusion/exclusion criteria. Follow-up duration ranged from 6-24 months. There were significant differences in intervention types and number of components in each intervention. Modest improvements were observed in more than half of the studies with weight related outcomes while no improvement was seen in virtually all the studies with physical activity outcome. In general, internet-based programs were more successful if the interventions also included some physical contact and environmental modification, and if they were targeted at specific disease entities such as hypertension. Only a few of the studies were conducted in persons at-risk for CVD, none in blue-collar workers or low-income earners. Internet based programs hold promise for improving the cardiovascular wellness among employees however much work is required to fully understand its utility and long term impact especially in special/at-risk populations.

    Child pedestrian injury is a preventable global health challenge. Successful training efforts focused on child behavior, including individualized streetside training and training in large virtual pedestrian environments, are laborious and expensive. This study considers the usability and feasibility of a virtual pedestrian environment “game” application to teach children safe street-crossing behavior via the internet, a medium that could be broadly disseminated at low cost. Ten 7- and 8-year-old children participated. They engaged in an internet-based virtual pedestrian environment and completed a brief assessment survey. Researchers rated children's behavior while engaged in the game. Both self-report and researcher observations indicated the internet-based system was readily used by the children without adult support. The youth understood how to engage in the system and used it independently and attentively. The program also was feasible. It provided multiple measures of pedestrian safety that could be used for research or training purposes. Finally, the program was rated by children as engaging and educational. Researcher ratings suggested children used the program with minimal fidgeting or boredom. The pilot test suggests an internet-based virtual pedestrian environment offers a usable, feasible, engaging, and educational environment for child pedestrian safety training. If future research finds children learn the cognitive and perceptual skills needed to cross streets safely within it, internet-based training may provide a low-cost medium to broadly disseminate child pedestrian safety training. The concept may be generalized to other domains of health-related functioning such as teen driving safety, adolescent sexual risk-taking, and adolescent substance use. PMID:24678263

    New technology offers increased opportunities for weight control. However, it is not clear whether older people with less computer training can make use of this tool. Our objective was to examine how members above the age of 65 years performed in an internet-based behavioral weight loss program, compared to younger members. Data from members (n = 23,233) of an internet-based behavioral weight loss program were analyzed. We restricted our study to active participants accessing the weight club, during a 6-month period (n = 4,440). The number of logins, food intake, and weight records were examined. Participants were divided into age tertiles separately for men and women. The oldest tertile was further subdivided into two groups: above and below the age of 65 years. Participants aged 65 or older were more likely to remain active in the weight club for at least 6 months compared to younger age groups. They had the highest frequency of recordings of food intake and current weight. Among women, those older than 65 years had on average the highest percentage of weight loss (5.6 kg, 6.8%). Men above 65 years of age had the highest number of logins, on average 161 times during the 6-month period. Older participants are performing equally well or even better in an internet-based behavioral weight loss program than younger participants. Internet-based programs could be a promising and attractive option for older adults requiring assistance in losing weight. 2009 S. Karger AG, Basel.

    To conduct a pilot trial of internet-based, cancer-adapted yoga for women receiving breast cancer treatment. Women undergoing radiation or chemotherapy for breast cancer were recruited for 12, 75-min, biweekly, cancer-adapted yoga classes delivered via internet-based, multipoint videoconferencing. Data were collected on feasibility and acceptability, including qualitative feedback from participants and the yoga instructor. Among 42 women approached, 13 declined eligibility screening, and 23 were ineligible. All 6 women who were eligible provided consent, but 2 withdrew prior to beginning yoga classes. The remaining 4 participants attended 1-11 of 12 online yoga classes. In post-intervention interviews, participants and the instructor agreed that internet-based yoga classes hold great potential for increasing access and improving psychological outcomes in adults with cancer. Qualitative feedback from participants revealed suggestions for future trials of internet-based, cancer-adapted yoga classes, including: continued use of group format; offering more varied class times to accommodate patients' demanding schedules and fluctuating symptoms; enrolling patients after they have acclimated to or completed cancer treatment; streamlining the technology interface; and careful attention to participant burden when designing surveys/forms. The instructor recommended closed session courses, as opposed to rolling enrollment; teaching the same modified poses for all participants, rather than individual tailoring; and using a large screen to allow closer monitoring of students' class experience. Internet delivery may increase patients' access to cancer-adapted yoga classes, but cancer-related and technological barriers remain. This study informs how to optimally design yoga classes, technology, and research procedures to maximize feasibility and acceptability in future trials. Copyright © 2018 Elsevier Ltd.

    Full Text Available Abstract Background Depression in MS patients is frequent but often not treated adequately. An important underlying factor may be physical limitations that preclude face-to-face contact. Internet-based treatment showed to be effective for depressive symptoms in general and could thus be a promising tool for treatment in MS. Methods/design Here, we present a study protocol to investigate the effectiveness of a 5 week Internet-based self-help problem solving treatment (PST for depressive symptoms in MS patients in a randomized controlled trial. We aim to include 166 MS patients with moderate to severe depressive symptoms who will be randomly assigned to an Internet-based intervention (with or without supportive text-messages or waiting list control group. The primary outcome is the change in depressive symptoms defined by a change in the sum score on the Beck Depression Inventory (BDI-II. Secondary outcomes will include measures of anxiety, fatigue, cognitive functioning, physical and psychological impact of MS, quality of life, problem solving skills, social support, mastery, satisfaction and compliance rate. Assessments will take place at baseline (T0, within a week after the intervention (T1, at four months (T2 and at ten months follow-up (T3: only the intervention group. The control group will be measured at the same moments in time. Analysis will be based on the intention-to-treat principle. Discussion If shown to be effective, Internet-based PST will offer new possibilities to reach and treat MS patients with depressive symptoms and to improve the quality of care.

    Since the beginning of 2007, the National Health Research Institutes has been promoting the dissemination of evidence-based medicine (EBM). The current study examined longitudinal trends of behaviors in how hospital-based physicians and nurses have searched for medical information during the spread of EBM. Cross-sectional postal questionnaire surveys were conducted in nationally representative regional hospitals of Taiwan thrice in 2007, 2009, and 2011. Demographic data were gathered concerning gender, age, working experience, teaching appointment, academic degree, and administrative position. Linear and logistic regression models were used to examine predictors and changes over time. Data from physicians and nurses were collected in 2007 (n = 1156), 2009 (n = 2975), and 2011 (n = 3999). There were significant increases in the use of four Internet-based resources - Web portals, online databases, electronic journals, and electronic books - across the three survey years among physicians and nurses (p Internet-based resources and users' characteristics. Age and faculty position were important predictors in relation to the usage among physicians and nurses, while academic degree served as a critical factor among nurses only. Physicians and nurses used a variety of sources to look for medical information. There was a steady increase in use of Internet-based resources during the diffusion period of EBM. The findings highlight the importance of the Internet as a prominent source of medical information for main healthcare professionals.

    Internet-based cancer risk assessment tools might serve as a strategy for translating epidemiological risk prediction research into public health practice. Understanding how such tools affect key social-cognitive precursors of behavior change is crucial for leveraging their potential into effective interventions. To test the effects of a publicly available, Internet-based, breast cancer risk assessment tool on social-cognitive precursors of physical activity. Women (N = 132) aged 40-78 with no personal cancer history indicated their perceived risk of breast cancer and were randomly assigned to receive personalized ( www.yourdiseaserisk.wustl.edu ) or nonpersonalized breast cancer risk information. Immediately thereafter, breast cancer risk perceptions and physical activity-related behavioral intentions, self-efficacy, and response efficacy were assessed. Personalized information elicited higher intentions, self-efficacy, and response efficacy than nonpersonalized information, P values Internet-based risk assessment tools can produce beneficial effects on important social-cognitive precursors of behavior change, but lingering skepticism, possibly due to defensive processing, needs to be addressed before the effects can be maximized.

    The overall goal of this study was to produce a user-friendly and high quality Internet-based patient education program for adolescents with psychosis. To achieve this, we ascertained the adolescents' and health care professionals' needs and expectations of patient education using Internet and the improvement proposals for an existing MentalNet program originally developed for adults with schizophrenia. The research process was conducted in two phases. First, adolescents' and healthcare professionals' needs for patient education and Internet were ascertained by interviewing adolescents and in two educational sessions with staff members (Phase I). Second, the preliminary evaluation of the Internet-based patient education program MentalNet was gathered from adolescents by an iterative process (see cyclic, recurring, repeating method), in one educational session with staff members and a questionnaire via email from other health care professionals (Phase II). The needs and expectations of adolescents and health care professionals were related to the content, usability, design and realization of Internet-based patient education. Based on the information obtained the MentalNet program was modified to satisfy adolescents' needs. The usefulness and effectiveness of the program will require scrutiny in future studies.

    Evidence shows that internet-based self-help interventions are effective in reducing symptoms for a wide range of mental disorders. To date, online interventions treating psychotic disorders have been scarce, even though psychosis is among the most burdensome disorders worldwide. Furthermore, the implementation of cognitive-behavioral therapy (CBT) for psychosis in routine health care is challenging. Internet-based interventions could narrow this treatment gap. Thus, a comprehensive CBT-based online self-help intervention for people with psychosis has been developed. The aim of this study is the evaluation of the feasibility and efficacy of the intervention compared with a waiting list control group. The intervention includes modules on delusion, voice hearing, social competence, mindfulness, and seven other domains. Participants are guided through the program by a personal moderator. Usage can be amended by an optional smartphone app. In this randomized controlled trial, participants are allocated to a waiting list or an intervention of eight weeks. Change in positive psychotic symptoms of both groups will be compared (primary outcome) and predictors of treatment effects will be assessed. To our knowledge, this project is one of the first large-scale investigations of an internet-based intervention for people with psychosis. It may thus be a further step to broaden treatment options for people suffering from this disorder. NCT02974400 (clinicaltrials.gov), date of registration: November 28th 2016.

    Changes in thoracoabdominal motion are highly prevalent in patients with chronic respiratory diseases. Home care services that use telemedicine techniques and Internet-based monitoring have the potential to improve the management of these patients. However, there is no detailed description in the literature of a system for Internet-based monitoring of patients with disturbed thoracoabdominal motion. The purpose of this work was to describe the development of a new telemedicine instrument for Internet-based home monitoring of thoracoabdominal movement. The instrument directly measures changes in the thorax and abdomen circumferences and transfers data through a transmission control protocol/Internet protocol connection. After the design details are described, the accuracy of the electronic and software processing units of the instrument is evaluated by using electronic signals simulating normal subjects and individuals with thoracoabdominal motion disorders. The results obtained during in vivo studies on normal subjects simulating thoracoabdominal motion disorders showed that this new system is able to detect a reduction in abdominal movement that is associated with abnormal thoracic breathing (p telemedicine scenarios, which can reduce the costs of assistance offered to patients with respiratory diseases.

    BACKGROUND: The impact of Chlamydia trachomatis (chlamydia) control on the incidence of pelvic inflammatory disease (PID) is theoretically limited by the proportion of PID caused by chlamydia. We estimate the population excess fraction (PEF) of treated chlamydia infection on PID at 12-months......: The systematic review identified a single study, a randomised controlled trial of chlamydia screening (POPI-RCT). In the presence of testing and treatment PID at 12-months was attributable to treated (baseline) chlamydia infections (Manitoba: 8.86%(95%CI 7.15-10.75); Denmark: 3.84%(3.26-4.45); screened...... in settings with widespread chlamydia control (testing and treatment) and compare this to the estimated PEF of untreated chlamydia. METHODS: We used two large retrospective population-based cohorts of women of reproductive age from settings with widespread chlamydia control to calculate the PEF of treated...

    2011-01-01

    Full Text Available Our aims were to genotype Chlamydia trachomatis strains present in urogenital samples and to investigate the occurrence of the Swedish new variant of C. trachomatis in Finland. We genotyped 160 C. trachomatis positive samples with ompA real-time PCR and analyzed 495 samples for the new variant. The three most prevalent genotypes were E (40%, F (28%, and G (13%. Only two specimens containing bacteria with the variant plasmid were detected. It seems that in Finland the percentage of infections due to genotypes F and G has slightly increased during the last 20 years. Genotypes E and G appear to be more common, and genotypes J/Ja and I/Ia appear to be less common in Europe than in the USA. Although the genotype E was the most common genotype among C. trachomatis strains, the new variant was rarely found in Finland.

    Full Text Available Abstract Background The metabolic syndrome together with insulin resistance and their consequences are basic factors in pathogenesis of atherosclerosis. Chronic infections with herpes simplex virus type 1 (HSV-1, cytomegalovirus (CMV, and Chlamydia pneumoniae are associated with the development of atherosclerosis and coronary heart disease. The infectious aspects of metabolic syndrome have not been investigated. Methods In a cross-sectional, population-based study, we used National Cholesterol Education Program (NCEP-Adult Treatment Panel (ATP-III criteria in 1791 subjects, aged 25 years and over, selected by cluster random sampling in three Iranian ports in the northern Persian Gulf. Sera were analyzed for IgG antibodies to Chlamydia pneumoniae, HSV-1, Helicobacter pylori (H. pylori and CMV using ELISA. Results In multiple logistic regression analysis, of the infectious agents, CMV [OR = 1.81 (1.05–3.10; p = 0.03], H. pylori [OR = 1.50 (1.12–2.00; p = 0.007] and Chlamydia pneumoniae [OR = 1.69 (1.27–2.25; p Conclusion The metabolic syndrome, which occurs very frequently in the general population, has a significant association with prior infection with Chlamydia pneumoniae, Helicobacter pylori, cytomegalovirus and herpes simplex virus type 1. Hypothesis about participation of infection in pathogenesis of metabolic syndrome should be investigated.

    Parrots are one of the most popular pet birds in China, and can harbour Chlamydia which has significance for human and animal health. We investigated, by indirect haemagglutination assay, the seroprevalence of Chlamydia infection in four species of parrots, namely budgerigars (Melopsittacus undulatus), lovebirds (Agapornis sp.), cockatiels (Nymphicus hollandicus) and Alexandrine parakeets (Psittacula eupatria) that were collected from Weifang and Beijing cities, North China and explored the association between potential risk factors and chlamydial seropositivity. We further determined the genotype of Chlamydia in 21 fresh faecal samples based on the ompA sequence by reconstruction of phylogenetic relationships. Of the 311 parrots examined, 35·37% (95% confidence interval 30·06-40·68) were seropositive, and species, gender, age, season and geographical location were identified as risk factors. Two PCR-positive samples represented Chlamydia psittaci genotype A. The occurrence of C. psittaci genotype A in the droppings of two pet parrots in China suggests potential environmental contamination with Chlamydiaceae and may raise a public health concern.

  9. Primary endosymbiosis: have cyanobacteria and Chlamydiae ever been roommates?

    Full Text Available Eukaryotes acquired the ability to process photosynthesis by engulfing a cyanobacterium and transforming it into a genuine organelle called the plastid. This event, named primary endosymbiosis, occurred once more than a billion years ago, and allowed the emergence of the Archaeplastida, a monophyletic supergroup comprising the green algae and plants, the red algae and the glaucophytes. Of the other known cases of symbiosis between cyanobacteria and eukaryotes, none has achieved a comparable level of cell integration nor reached the same evolutionary and ecological success than primary endosymbiosis did. Reasons for this unique accomplishment are still unknown and difficult to comprehend. The exploration of plant genomes has revealed a considerable amount of genes closely related to homologs of Chlamydiae bacteria, and probably acquired by horizontal gene transfer. Several studies have proposed that these transferred genes, which are mostly involved in the functioning of the plastid, may have helped the settlement of primary endosymbiosis. Some of these studies propose that Chlamydiae and cyanobacterial symbionts coexisted in the eukaryotic host of the primary endosymbiosis, and that Chlamydiae provided solutions for the metabolic symbiosis between the cyanobacterium and the host, ensuring the success of primary endosymbiosis. In this review, I present a reevaluation of the contribution of Chlamydiae genes to the genome of Archaeplastida and discuss the strengths and weaknesses of this tripartite model for primary endosymbiosis.

    Voigt, Anja; Schöfl, Gerhard; Saluz, Hans Peter

    2012-01-01

    Chlamydiaceae are a family of obligate intracellular pathogens causing a wide range of diseases in animals and humans, and facing unique evolutionary constraints not encountered by free-living prokaryotes. To investigate genomic aspects of infection, virulence and host preference we have sequenced Chlamydia psittaci, the pathogenic agent of ornithosis. A comparison of the genome of the avian Chlamydia psittaci isolate 6BC with the genomes of other chlamydial species, C. trachomatis, C. muridarum, C. pneumoniae, C. abortus, C. felis and C. caviae, revealed a high level of sequence conservation and synteny across taxa, with the major exception of the human pathogen C. trachomatis. Important differences manifest in the polymorphic membrane protein family specific for the Chlamydiae and in the highly variable chlamydial plasticity zone. We identified a number of psittaci-specific polymorphic membrane proteins of the G family that may be related to differences in host-range and/or virulence as compared to closely related Chlamydiaceae. We calculated non-synonymous to synonymous substitution rate ratios for pairs of orthologous genes to identify putative targets of adaptive evolution and predicted type III secreted effector proteins. This study is the first detailed analysis of the Chlamydia psittaci genome sequence. It provides insights in the genome architecture of C. psittaci and proposes a number of novel candidate genes mostly of yet unknown function that may be important for pathogen-host interactions.

    Given the lack of information concerning the role of Chlamydia trachomatis in male fertility, the aim of this study was to ascertain and analyze the quality of Chlamydiae-positive and -negative semen. Sperm count was performed according to the 1999 World Health Organization (WHO) laboratory manual for examination of human semen and sperm-cervical mucus interaction, and sperm survival was assessed by a 120-min test. The evaluation of the morphological examination of ejaculates was carried out using the sasmo (strict morphological analysis of ejaculates) computer program. Chlamydiae were detected by immunofluorescent reaction using the Progen Biotechnik GmbH diagnostic set. Fisher's exact test and the chi-quadrate test were used for statistical analysis. Of the total of 627 sperm samples examined, Chlamydiae were detected in 136 cases (21.7%). Sperm analysis showed significant differences between Chlamydiae-positive and -negative samples. The Chlamydiae-contaminated group showed normal sperm morphology 14.4% lower, volume 6.4% lower, concentration 8.3% lower, motility 7.8% and velocity 9.3% lower than in Chlamydiae-negative samples. The average values for normal spermatozoa and motility in the Chlamydiae-positive group were also significantly reduced. Chlamydia trachomatis was found to be a possible factor in sperm pathology. These results could help to elucidate the role of Chlamydia trachomatis in male infertility.

    Background Since legislation prohibiting tobacco advertising in traditional media, online communication platforms and social media have become one of the few avenues for the tobacco industry to promote its products to Australians. Little is currently known about the exposure of young people to these new media promotions. Objective To measure exposure to Internet-based tobacco advertising and branding among Australian youth, identify common formats of branding encountered, and examine the association between exposure and smoking susceptibility. Methods The Tobacco Promotion Impact Study is a repeat cross-sectional telephone survey of young people (12-24 years) in 2 Australian states, conducted yearly from 2010 to 2013 (total n=8820). The survey included questions about past-month exposure to Internet-based tobacco advertising and tobacco company branding. Changes in levels of exposure, characteristics of exposed youth, and the association between exposure and smoking susceptibility were explored. Results Past-month exposure to Internet-based tobacco advertising and branding among young people increased over the years of the survey (advertising: 21% in 2010 to 29% in 2013; branding: 20% in 2010 to 26% in 2013). The participants who were younger, female, from lower socioeconomic status, and never-smokers were more likely to report exposure. Facebook was the most commonly cited platform for encountering tobacco branding in 2013 (22% of all branding). Compared with young people interviewed in 2013, participants in 2010 were significantly less likely to report exposure to tobacco branding on social media (odds ratio [OR] 0.26, 95% CI 0.20-0.33, Pbranding (OR 1.32, 95% CI 1.11-1.57, P=.002) or branding alone (OR 1.39, 95% CI 1.10-1.77, P=.007) were significant predictors of smoking susceptibility. Conclusions Ensuring tobacco advertising bans are inclusive of Internet-based media is essential. Given the global nature of Internet-based content, cooperation among signatory

    To evaluate the efficacy of therapist guided internet based cognitive behavioural therapy (CBT) programme for body dysmorphic disorder (BDD-NET) compared with online supportive therapy. A 12 week single blind parallel group randomised controlled trial. Academic medical centre. 94 self referred adult outpatients with a diagnosis of body dysmorphic disorder and a modified Yale-Brown obsessive compulsive scale (BDD-YBOCS) score of ≥ 20. Concurrent psychotropic drug treatment was permitted if the dose had been stable for at least two months before enrolment and remained unchanged during the trial. Participants received either BDD-NET (n=47) or supportive therapy (n=47) delivered via the internet for 12 weeks. The primary outcome was the BDD-YBOCS score after treatment and follow-up (three and six months from baseline) as evaluated by a masked assessor. Responder status was defined as a ≥ 30% reduction in symptoms on the scale. Secondary outcomes were measures of depression (MADRS-S), global functioning (GAF), clinical global improvement (CGI-I), and quality of life (EQ5D). The six month follow-up time and all outcomes other than BDD-YBOCS and MADRS-S at 3 months were not pre-specified in the registration at clinicaltrials.gov because of an administrative error but were included in the original trial protocol approved by the regional ethics committee before the start of the trial. BDD-NET was superior to supportive therapy and was associated with significant improvements in severity of symptoms of body dysmorphic disorder (BDD-YBOCS group difference -7.1 points, 95% confidence interval -9.8 to -4.4), depression (MADRS-S group difference -4.5 points, -7.5 to -1.4), and other secondary measures. At follow-up, 56% of those receiving BDD-NET were classed as responders, compared with 13% receiving supportive therapy. The number needed to treat was 2.34 (1.71 to 4.35). Self reported satisfaction was high. CBT can be delivered safely via the internet to patients with body

    Internet-based developmental screening is being implemented in pediatric practices across the United States. Little is known about the application of this technology in poor urban populations. We describe here the results of focus groups, surveys, and in-depth interviews during home visits with families served by an urban safety-net organization to address the question of whether it is possible to use Internet or e-mail communication for medical previsit engagement in a population that is majority Hispanic, of low socioeconomic status, and has many non-English-speaking families. This study included families in 4 clinics within a safety-net health care system. The study design included the use of (1) parental surveys (n = 200) of a convenience sample of parents whose children received primary care in the clinics, (2) focus groups (n = 7 groups) with parents, and (3) in-depth interviews during home visits with 4 families. We used χ(2) and multivariate analyses to compare Internet access in English- and Spanish-speaking families. Standard qualitative methods were used to code focus-group texts and identify convergent themes. In multivariate analysis, independent factors associated with computer use were English versus Spanish language (odds ratio: 3.2 [95% confidence interval: 1.4-6.9]) and education through at least high school (odds ratio: 4.7 [95% confidence interval: 2.3-9.7]). In focus groups, the concept of parental previsit work, such as developmental screening tests, was viewed favorably by all groups. However, many parents expressed reservations about doing this work by using the Internet or e-mail and stated a preference for either paper or telephone options. Many Spanish-speaking families discussed lack of access to computers and printers. In this economically disadvantaged population, language and maternal education were associated with access to the Internet. Given the potential power of previsit work to tailor well-child visits to the needs of

    Full Text Available Abstract Background Pain variability in acute LBP has received limited study. The objectives of this pilot study were to characterize fluctuations in pain during acute LBP, to determine whether self-reported 'flares' of pain represent discrete periods of increased pain intensity, and to examine whether the frequency of flares was associated with back-related disability outcomes. Methods We conducted a cohort study of acute LBP patients utilizing frequent serial assessments and Internet-based data collection. Adults with acute LBP (lasting ≤3 months completed questionnaires at the time of seeking care, and at both 3-day and 1-week intervals, for 6 weeks. Back pain was measured using a numerical pain rating scale (NPRS, and disability was measured using the Oswestry Disability Index (ODI. A pain flare was defined as 'a period of increased pain lasting at least 2 hours, when your pain intensity is distinctly worse than it has been recently'. We used mixed-effects linear regression to model longitudinal changes in pain intensity, and multivariate linear regression to model associations between flare frequency and disability outcomes. Results 42 of 47 participants (89% reported pain flares, and the average number of discrete flare periods per patient was 3.5 over 6 weeks of follow-up. More than half of flares were less than 4 hours in duration, and about 75% of flares were less than one day in duration. A model with a quadratic trend for time best characterized improvements in pain. Pain decreased rapidly during the first 14 days after seeking care, and leveled off after about 28 days. Patients who reported a pain flare experienced an almost 3-point greater current NPRS than those not reporting a flare (mean difference [SD] 2.70 [0.11]; p ß [SE} 0.28 (0.08; p = 0.002. Conclusions Acute LBP is characterized by variability. Patients with acute LBP report multiple distinct flares of pain, which correspond to discrete increases in pain intensity. A

    The NASA Glenn Research Center successfully demonstrated a transmission-control-protocol/ Internet-protocol- (TCP/IP) based approach to the command and control of onorbit assets over a secure network. This is a significant accomplishment because future NASA missions will benefit by using Internet-standards-based protocols. Benefits of this Internet-based space command and control system architecture include reduced mission costs and increased mission efficiency. The demonstration proved that this communications architecture is viable for future NASA missions. This demonstration was a significant feat involving multiple NASA organizations and industry. Phillip Paulsen, from Glenn's Project Development and Integration Office, served as the overall project lead, and David Foltz, from Glenn's Satellite Networks and Architectures Branch, provided the hybrid networking support for the required Internet connections. The goal was to build a network that would emulate a connection between a space experiment on the International Space Station and a researcher accessing the experiment from anywhere on the Internet, as shown. The experiment was interfaced to a wireless 802.11 network inside the demonstration area. The wireless link provided connectivity to the Tracking and Data Relay Satellite System (TDRSS) Internet Link Terminal (TILT) satellite uplink terminal located 300 ft away in a parking lot on top of a panel van. TILT provided a crucial link in this demonstration. Leslie Ambrose, NASA Goddard Space Flight Center, provided the TILT/TDRSS support. The TILT unit transmitted the signal to TDRS 6 and was received at the White Sands Second TDRSS Ground Station. This station provided the gateway to the Internet. Coordination also took place at the White Sands station to install a Veridian Firewall and automated security incident measurement (ASIM) system to the Second TDRSS Ground Station Internet gateway. The firewall provides a trusted network for the simulated space

    Posttraumatic stress disorder (PTSD) develops in 10-20% of injury patients. We developed a novel, self-guided Internet-based intervention (called Trauma TIPS) based on techniques from cognitive behavioral therapy (CBT) to prevent the onset of PTSD symptoms. To determine whether Trauma TIPS is effective in preventing the onset of PTSD symptoms in injury patients. Adult, level 1 trauma center patients were randomly assigned to receive the fully automated Trauma TIPS Internet intervention (n=151) or to receive no early intervention (n=149). Trauma TIPS consisted of psychoeducation, in vivo exposure, and stress management techniques. Both groups were free to use care as usual (nonprotocolized talks with hospital staff). PTSD symptom severity was assessed at 1, 3, 6, and 12 months post injury with a clinical interview (Clinician-Administered PTSD Scale) by blinded trained interviewers and self-report instrument (Impact of Event Scale-Revised). Secondary outcomes were acute anxiety and arousal (assessed online), self-reported depressive and anxiety symptoms (Hospital Anxiety and Depression Scale), and mental health care utilization. Intervention usage was documented. The mean number of intervention logins was 1.7, SD 2.5, median 1, interquartile range (IQR) 1-2. Thirty-four patients in the intervention group did not log in (22.5%), 63 (41.7%) logged in once, and 54 (35.8%) logged in multiple times (mean 3.6, SD 3.5, median 3, IQR 2-4). On clinician-assessed and self-reported PTSD symptoms, both the intervention and control group showed a significant decrease over time (PInternet-based early intervention in the prevention of PTSD symptoms for an unselected population of injury patients. Moreover, uptake was relatively low since one-fifth of individuals did not log in to the intervention. Future research should therefore focus on innovative strategies to increase intervention usage, for example, adding gameplay, embedding it in a blended care context, and targeting high

    Full Text Available This article is a reflection on the problems, challenges and strengths of network-based distance learning in archaeology. Based on the experience of one project - the PATOIS (Publications and Archives Teaching with Online Information Systems Project - it looks at how archaeologists might best respond (and by implication how they ought not to respond to the use of information technology in teaching. The PATOIS project is an attempt on behalf of a consortium of UK higher education institutions and allied research bodies to tell students about the information tools that are emerging in archaeology, and which are changing the culture of scholarship. Funded by the Joint Information Systems Committee (JISC and led by the Archaeology Data Service (ADS, PATOIS presents students with these new research tools and novel forms of academic literacy by direct exposure to 'primary' datasets. The PATOIS project is producing a set of Internet-based tutorials that lead students through different datasets and show how they may be deployed in research. This article describes the institutional and intellectual background to the project, and reports on the content of the tutorials themselves. Perhaps more importantly, it looks at the process through which PATOIS was developed, reviewing the challenges and constraints that the development team faced. Thereafter, we turn to the implementation of PATOIS in real teaching scenarios and look at how and when these have been successful as well as the challenges that remain unanswered. The project is not yet complete, so at this stage we can come to no firm conclusions about the long-term impact of PATOIS in facilitating change in undergraduate research training. Nonetheless, from the perspective of development work, the project has largely been completed, so those conclusions that may be drawn are most appropriately addressed to developers hoping or planning to undertake similar work in the future, or academics looking to

    The Southern California Seismic Network (SCSN), operated by Caltech and USGS, leverages modern Internet-based computing technologies to provide timely earthquake early warning for damage reduction, event notification, ShakeMap, and other data products. Here we present recent and ongoing innovations in telemetry, security, cloud computing, virtualization, and data analysis that have allowed us to develop a network that runs securely and efficiently.Earthquake early warning systems must process seismic data within seconds of being recorded, and SCSN maintains a robust and resilient network of more than 350 digital strong motion and broadband seismic stations to achieve this goal. We have continued to improve the path diversity and fault tolerance within our network, and have also developed new tools for latency monitoring and archiving.Cyberattacks are in the news almost daily, and with most of our seismic data streams running over the Internet, it is only a matter of time before SCSN is targeted. To ensure system integrity and availability across our network, we have implemented strong security, including encryption and Virtual Private Networks (VPNs).SCSN operates its own data center at Caltech, but we have also installed real-time servers on Amazon Web Services (AWS), to provide an additional level of redundancy, and eventually to allow full off-site operations continuity for our network. Our AWS systems receive data from Caltech-based import servers and directly from field locations, and are able to process the seismic data, calculate earthquake locations and magnitudes, and distribute earthquake alerts, directly from the cloud.We have also begun a virtualization project at our Caltech data center, allowing us to serve data from Virtual Machines (VMs), making efficient use of high-performance hardware and increasing flexibility and scalability of our data processing systems.Finally, we have developed new monitoring of station average noise levels at most stations

    The Internet could provide a means of delivering secondary prevention programmes to people with coronary heart disease (CHD). To determine the effectiveness of Internet-based interventions targeting lifestyle changes and medicines management for the secondary prevention of CHD. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, in December 2014. We also searched six other databases in October 2014, and three trials registers in January 2015 together with reference checking and handsearching to identify additional studies. Randomised controlled trials (RCTs) evaluating Internet-delivered secondary prevention interventions aimed at people with CHD. Two review authors independently assessed risk of bias and extracted data according to the Cochrane Handbook for Systematic Reviews of Interventions. We assessed evidence quality using the GRADE approach and presented this in a 'Summary of findings' table. Eighteen trials met our inclusion criteria. Eleven studies are complete (1392 participants), and seven are ongoing. Of the completed studies, seven interventions are broad, targeting the lifestyle management of CHD, and four focused on physical activity promotion. The comparison group in trials was usual care (n = 6), minimal intervention (n = 3), or traditional cardiac rehabilitation (n = 2).We found no effects of Internet-based interventions for all-cause mortality (odds ratio (OR) 0.27, 95% confidence interval (CI) 0.04 to 1.63; participants = 895; studies = 6; low-quality evidence). There was only one case of cardiovascular mortality in a control group (participants = 895; studies = 6). No incidences of non-fatal re-infarction were reported across any of the studies. We found no effects for revascularisation (OR 0.69, 95% CI 0.37 to 1.27; participants = 895; studies = 6; low-quality evidence).We found no effects for total cholesterol (mean difference (MD) 0.00, 95% CI -0.27 to 0.28; participants = 439; studies = 4; low

    The Kodak Surecell Chlamydia test, a rapid enzyme immunoassay, has been reported to be highly sensitive (93%) and specific (96%) for detecting chlamydial lipopolysaccharide antigen in conjunctival specimens from infants, but has not been evaluated previously in adult conjunctival specimens. This study was designed to determine the efficacy of the Kodak Surecell Chlamydia test for the laboratory diagnosis of adult inclusion conjunctivitis. Twenty Chlamydia culture-positive conjunctival specimens from adults (true-positives) and 20 true-negative specimens were tested with the Kodak Surecell Chlamydia test. The Kodak Surecell Chlamydia test was 40% (8/20) sensitive, 100% (20/20) specific, and 70% (28/40) efficient. This study indicates that the Kodak Surecell Chlamydia test, though highly specific, is less sensitive in its ability to diagnose chlamydial conjunctivitis in adults than has been reported previously in infants.

    We used serology to estimate the prevalence of exposure to chlamydiae in Italian populations of wild boars (Sus scrofa). Sera from 173 hunter-killed wild boars harvested during the 2006-2009 hunting seasons in three Italian regions were tested for antibodies to Chlamydia suis, Chlamydophila pecorum, Chlamydophila abortus, and Chlamydophila psittaci by the microimmunofluorescence test. Antibody titers to chlamydiae ≥ 1:32 were detected in 110 of the 173 samples tested (63.6%). Specific reactivity could be assessed only in 44 sera with antibody titers to C. suis that were two- to threefold higher than antibody titers against the other chlamydial species; the other 66 sera had similar reactivity against all the chlamydia species tested. Antibody to C. suis was detected in sera from wild boar populations with rare or no known contact with domestic pigs. These results suggest that the wild boar could be a chlamydia reservoir and may acquire chlamydiae independent of contacts with the domestic pig.

    Full Text Available Trachoma control programs utilize mass azithromycin distributions to treat ocular Chlamydia trachomatis as part of an effort to eliminate this disease world-wide. But it remains unclear what the community-level risk factors are for infection.This cluster-randomized, controlled trial entered 48 randomly selected communities in a 2×2 factorial design evaluating the effect of different treatment frequencies and treatment coverage levels. A pretreatment census and examination established the prevalence of risk factors for clinical trachoma and ocular chlamydia infection including years of education of household head, distance to primary water source, presence of household latrine, and facial cleanliness (ocular discharge, nasal discharge, and presence of facial flies. Univariate and multivariate associations were tested using linear regression and Bayes model averaging.There were a total of 24,536 participants (4,484 children aged 0-5 years in 6,235 households in the study. Before treatment in May to July 2010, the community-level prevalence of active trachoma (TF or TI utilizing the World Health Organization [WHO] grading system was 26.0% (95% CI: 21.9% to 30.0% and the mean community-level prevalence of chlamydia infection by Amplicor PCR was 20.7% (95% CI: 16.5% to 24.9% in children aged 0-5 years. Univariate analysis showed that nasal discharge (0.29, 95% CI: 0.04 to 0.54; P = 0.03, presence of flies on the face (0.40, 95% CI: 0.17 to 0.64; P = 0.001, and years of formal education completed by the head of household (0.07, 95% CI: 0.07 to 0.13; P = 0.03 were independent risk factors for chlamydia infection.

    Tobacco smoking leads to death or disability and a drain on national resources. The literature suggests that cigarette smoking continues to be a major modifiable risk factor for a variety of diseases and that smokers aged 18-30 years are relatively resistant to antismoking messages due to their widely held belief that they will not be lifelong smokers. To conduct a randomized controlled trial (RCT) of a computer-generated photoaging intervention to promote smoking cessation among young adult smokers within a community pharmacy setting. A trial was designed with 80% power based on the effect size observed in a published pilot study; 160 subjects were recruited (80 allocated to the control group and 80 to the intervention group) from 8 metropolitan community pharmacies located around Perth city center in Western Australia. All participants received standardized smoking cessation advice. The intervention group participants were also digitally photoaged by using the Internet-based APRIL Face Aging software so they could preview images of themselves as a lifelong smoker and as a nonsmoker. Due to the nature of the intervention, the participants and researcher could not be blinded to the study. The main outcome measure was quit attempts at 6-month follow-up, both self-reported and biochemically validated through testing for carbon monoxide (CO), and nicotine dependence assessed via the Fagerström scale. At 6-month follow-up, 5 of 80 control group participants (6.3%) suggested they had quit smoking, but only 1 of 80 control group participants (1.3%) consented to, and was confirmed by, CO validation. In the intervention group, 22 of 80 participants (27.5%) reported quitting, with 11 of 80 participants (13.8%) confirmed by CO testing. This difference in biochemically confirmed quit attempts was statistically significant (χ(2) 1=9.0, P=.003). A repeated measures analysis suggested the average intervention group smoking dependence score had also significantly dropped

    Internet-based health programs have been shown to be effective in reducing risk for cardiovascular disease. However, their rates of enrollment and engagement remain low. It is currently unclear whether rewards from established loyalty programs can serve as a conditioned stimulus to improve the use of a freely available Internet-based program. The objectives of the study were to (1) examine enrollment rates and levels of engagement with the My Health eSupport program between a Conditioned Reward group and a Control group, and (2) investigate the influence of loyalty rewards and participant characteristics on levels of enrollment and program engagement. The study sample (n=142,726) consisted of individuals who were offered enrollment in an Internet-based health intervention (My Health eSupport) after completing the Heart&Stroke Risk Assessment on the Heart and Stroke Foundation website. My Health eSupport programs provided encouragement and tips for lifestyle change. This is a free, self-guided, fully automated program that proactively delivers tailored email messages at 2-week intervals based on the participant's stage of motivational "readiness" and priority for lifestyle change. Participants in the Conditioned Reward group were offered a single exposure of 20 loyalty reward points from the Air Miles loyalty program for completing the Heart&Stroke Risk Assessment (10 reward points) and enrolling in the Internet-based program (10 reward points). Meanwhile, no rewards were given to the Control group participants. All data were collected between February 1, 2011 and February 10, 2012. In total, 51.38% (73,327/142,726) of individuals in the Conditioned Reward group and 48.62% (69,399/142,726) of individuals in the Control group completed the Heart&Stroke Risk Assessment. Subsequently, significantly more individuals from the Conditioned Reward group (52.96%, 38,835/73,327) enrolled in the My Health eSupport program than Controls (4.07%, 2826/69,399).

    Innovative approaches are needed to promote physical activity among young adult overweight and obese African American women. We sought to describe key elements that African American women desire in a culturally relevant Internet-based tool to promote physical activity among overweight and obese young adult African American women. A mixed-method approach combining nominal group technique and traditional focus groups was used to elicit recommendations for the development of an Internet-based physical activity promotion tool. Participants, ages 19 to 30 years, were enrolled in a major university. Nominal group technique sessions were conducted to identify themes viewed as key features for inclusion in a culturally relevant Internet-based tool. Confirmatory focus groups were conducted to verify and elicit more in-depth information on the themes. Twenty-nine women participated in nominal group (n = 13) and traditional focus group sessions (n = 16). Features that emerged to be included in a culturally relevant Internet-based physical activity promotion tool were personalized website pages, diverse body images on websites and in videos, motivational stories about physical activity and women similar to themselves in size and body shape, tips on hair care maintenance during physical activity, and online social support through social media (eg, Facebook, Twitter). Incorporating existing social media tools and motivational stories from young adult African American women in Internet-based tools may increase the feasibility, acceptability, and success of Internet-based physical activity programs in this high-risk, understudied population.

    Full Text Available Chlamydia spp. are obligate intracellular bacteria distributed all over the world, known to cause various forms of diseases in animals and humans. In the present study, a serological survey was conducted to detect the seroprevalence and risk factors associated with rabbit chlamydiosis in northeast China, including Liaoning province, Jilin province, Heilongjiang province, and Inner Mongolia Autonomous Region. Antibodies to Chlamydia were determined by indirect hemagglutination assay (IHA. The overall seroprevalence was estimated at 17.88% in total of 800 blood samples. The Chlamydia seroprevalence varied in domestic rabbits from different factors, and genders of domestic rabbits were considered as major risk factors associated with Chlamydia infection. Our study revealed a widespread and high prevalence of Chlamydia infection in domestic rabbits in northeast China, with higher exposure risk in female domestic rabbits. These findings suggested the potential importance of domestic rabbits in the transmission of zoonotic Chlamydia infection, and thus Chlamydia should be taken into consideration in diagnosing rabbit diseases. To our knowledge, there is no report of Chlamydia infection in domestic rabbits in China and the results extend the host range for Chlamydia, which has important implications for public health and the local economy.

  4. Chlamydia species-dependent differences in the growth requirement for lysosomes.

    Full Text Available Genome reduction is a hallmark of obligate intracellular pathogens such as Chlamydia, where adaptation to intracellular growth has resulted in the elimination of genes encoding biosynthetic enzymes. Accordingly, chlamydiae rely heavily on the host cell for nutrients yet their specific source is unclear. Interestingly, chlamydiae grow within a pathogen-defined vacuole that is in close apposition to lysosomes. Metabolically-labeled uninfected host cell proteins were provided as an exogenous nutrient source to chlamydiae-infected cells, and uptake and subsequent labeling of chlamydiae suggested lysosomal degradation as a source of amino acids for the pathogen. Indeed, Bafilomycin A1 (BafA1, an inhibitor of the vacuolar H(+/ATPase that blocks lysosomal acidification and functions, impairs the growth of C. trachomatis and C. pneumoniae, and these effects are especially profound in C. pneumoniae. BafA1 induced the marked accumulation of material within the lysosomal lumen, which was due to the inhibition of proteolytic activities, and this response inhibits chlamydiae rather than changes in lysosomal acidification per se, as cathepsin inhibitors also inhibit the growth of chlamydiae. Finally, the addition of cycloheximide, an inhibitor of eukaryotic protein synthesis, compromises the ability of lysosomal inhibitors to block chlamydial growth, suggesting chlamydiae directly access free amino acids in the host cytosol as a preferred source of these nutrients. Thus, chlamydiae co-opt the functions of lysosomes to acquire essential amino acids.

    Low levels of engagement in Internet-based interventions are common. Understanding users' experiences with these interventions is a key to improving efficacy. Although qualitative methods are well-suited for this purpose, few qualitative studies have been conducted in this area. In the present study, we assessed experiences with an Internet-based intervention among cancer survivors who made minimal use of the intervention. Semi-structured interviews were conducted with 25 cancer survivors who were minimally engaged (i.e., spent around 1 h total on website) with the online intervention, health-space.net. The intervention was a 12-week, facilitated support group with social and informational components. Interviews were analyzed using an interpretive descriptive design. Three broad categories, consisting of 18 specific themes, were identified from the interviews, which included connecting with similar others, individual expectations, and problems with the site (Κ = 0.88). The 'similar others' category reflected the significance of interacting with relatable survivors (i.e., same cancer type), the 'individual expectations' category reflected the significance of participants' expectations about using online interventions (i.e., personally relevant information), and the 'problems with the site' category reflected the significance of study procedures (i.e., website structure). The data indicate that minimally engaged participants have high variability regarding their needs and preferences for Internet-based interventions. Using qualitative methodologies to identify and incorporate these needs into the next generation of interventions has the potential to increase engagement and outcomes. The current study provides a foundation for future research to characterize survivors' needs and offer suggestions for better meeting these needs. Copyright © 2013 John Wiley & Sons, Ltd.

    Background Interventions using sustained aerobic exercise programs to aid smoking cessation have resulted in modest, short-term cessation rates comparable to conventional cessation methods. No smoking cessation trial to date has prescribed intermittent bouts of exercise in response to nicotine cravings. Objectives This pilot randomized controlled trial examined the feasibility and efficacy of an Internet-based smoking cessation program alone (CON) vs. the same Internet-based program + intermittent exercise in response to cigarette cravings (EX). Study population Participants (N = 38; mean age = 43.6 [SD = 11.5]; 60.5% women) were generally healthy, inactive adult smokers who desired to quit. Results The overall retention rate was 60.5% (n = 23), and no significant retention rate differences were found between groups (EX vs. CON). Although retained participants achieved a higher cessation rate (26.1%) than all enrolled participants (15.8%), adjusted intent-to-treat and per-protocol binary logistic regression analyses revealed no significant cessation rate differences between EX and CON groups. Linear regression results indicated that additional days of self-reported exercise on the study website during the intervention phase predicted significantly higher reduction rates among EX group participants, F(2, 16) = 31.08, p exercise in the presence of the apparently valuable Internet-based smoking cessation program. The results support findings from related research and underscore the need for additional investigation into both the mechanisms underlying the effect of exercise on cigarette cravings and the challenges of poor adherence in the context of exercise-based smoking cessation interventions.

    Binge-eating disorder (BED) is a prevalent health condition associated with obesity. Few people with BED receive appropriate treatment. Personal barriers include shame, fear of stigma, geographic distance to mental health services, and long wait-lists. The aims of this study were to examine the efficacy of an Internet-based cognitive-behavioral intervention for adults with threshold BED (DSM-IV) and to examine the stability of treatment effects over 12months. Participants were randomly assigned to a 16-week Internet-based cognitive-behavioral intervention (n=69) or a wait-list condition (n=70). Binge-eating frequency and eating disorder psychopathology were measured with the Eating Disorder Examination-Questionnaire and the Eating Disorder Examination administered over the telephone. Additionally, body weight and body mass index, depression, and anxiety were assessed before and immediately after treatment. Three-, 6-, and 12-month follow-up data were recorded in the treatment group. Immediately after the treatment the number of binge-eating episodes showed significant improvement (d=1.02, between group) in the treatment group relative to the wait-list condition. The treatment group had also significantly reduced symptoms of all eating psychopathology outcomes relative to the wait-list condition (0.82≤d≤1.11). In the treatment group significant improvement was still observed for all measures 1year after the intervention relative to pretreatment levels. The Internet-based intervention proved to be efficacious, significantly reducing the number of binge-eating episodes and eating disorder pathology long term. Low-threshold e-health interventions should be further evaluated to improve treatment access for patients suffering from BED. Copyright © 2016. Published by Elsevier Ltd.

    Within recent years public health interventions have become technologically based to reflect the digital age we currently live in and appeal to the public in innovative and novel ways. The Internet breaks down boundaries distance imposes and increases our ability to reach and connect with people. Internet-based interventions have the potential to expand access to effective behavioral interventions. The US National HIV/AIDS Strategy states that people living with HIV should have access to effective behavioral interventions like Healthy Relationships (HR) to help them develop safe sex and disclosure skills. However, access to HR is limited across the country, especially for people in remote or rural areas. Internet-based Healthy Relationships Video Groups (HR-VG) delivered at home or community based organizations (CBOs) can possibly expand access. This study assesses the preferences of women living with HIV (WLH) for participation in HR-VG among 21 WLH who participated in a randomized control trial (RCT) testing HR-VG and completed open-ended semi-structured telephone interviews. Transcripts were thematically analyzed to determine advantages, disadvantages and overall preference for home or agency delivery of HR-VG. Themes relating to convenience, technology access, privacy, distractions, HIV serostatus disclosure and social opportunities were identified as advantages or disadvantages to participating in HR-VG at each location. Overall privacy was the most salient concern of accessing HR-VG at home or at a CBO. Considering the concerns expressed by WLH, further studies are needed to assess how an Internet-based intervention delivered at home for WLH can maintain privacy while being cost effective.

    Background Young Chilean women between 18 and 24 years of age are at high risk of contracting sexually transmitted infection (STI) and human immunodeficiency virus (HIV). The literature shows a shortage of STI–HIV prevention interventions focused on this specific high-risk population and a unique set of barriers to receiving prevention messages. Internet-based interventions are promising for delivering STI–HIV prevention interventions and avoiding barriers to services. Aims The study aimed to develop a culturally informed Internet-based STI–HIV prevention intervention for Chilean women between 18 and 24 years of age, to investigate its feasibility and acceptability, and to compile recommendations on what would make the intervention more acceptable and feasible for these women. Methods The development of the Internet intervention was facilitated by a process that featured consultation with content and technology experts. A pre-post test design was used to test the acceptability and feasibility of the intervention with 40 young Chilean women between 18 and 24 years of age. Results The intervention website consisted of four modules of content and activities that support learning. The intervention was feasible and acceptable for young Chilean women between 18 and 24 years of age. Discussion and conclusion This study demonstrated the value of engaging multiple expert panels to develop culturally informed and technology-based interventions. The results of this study support the feasibility and acceptability of conducting an Internet-based intervention with multiple sessions, yielding high participation rates in a population in which there are barriers to discussion of STI–HIV prevention and sex-related content. Implications for nursing and health policy The outcomes have implications for nursing education and clinical practice and they can be used for the legal and judicial systems to promote or reinforce policies that encourage STI–HIV prevention strategies

    Full Text Available Obesity is an increasing public health problem affecting young people. The causes of obesity are multi-factorial among Chinese youth including lack of physical activity and poor eating habits. The use of an internet curriculum and cell phone reminders and texting may be an innovative means of increasing follow up and compliance with obese teens. The objectives of this study were to determine the feasibility of using an adapted internet curriculum and existing nutritional program along with cell phone follow up for obese Chinese teens.This was a randomized controlled study involving obese teens receiving care at a paediatric obesity clinic of a tertiary care hospital in Hong Kong. Forty-eight subjects aged 12 to 18 years were randomized into three groups. The control group received usual care visits with a physician in the obesity clinic every three months. The first intervention (IT group received usual care visits every three months plus a 12-week internet-based curriculum with cell phone calls/texts reminders. The second intervention group received usual care visits every three months plus four nutritional counselling sessions.The use of the internet-based curriculum was shown to be feasible as evidenced by the high recruitment rate, internet log-in rate, compliance with completing the curriculum and responses to phone reminders. No significant differences in weight were found between IT, sLMP and control groups.An internet-based curriculum with cell phone reminders as a supplement to usual care of obesity is feasible. Further study is required to determine whether an internet plus text intervention can be both an effective and a cost-effective adjunct to changing weight in obese youth.Chinese Clinical Trial Registry ChiCTR-TRC-12002624.

    The high prevalence rate of asthma represents a major societal burden. Advancements in information technology continue to affect the delivery of patient care in all areas of medicine. Internet-based solutions, social media, and mobile technology could address some of the problems associated with increasing asthma prevalence. This review evaluates Internet-based asthma interventions that were published between 2004 and October 2014 with respect to the use of behavioral change theoretical frameworks, applied clinical guidelines, and assessment tools. The search term (Asthma AND [Online or Internet or Mobile or Application or eHealth or App]) was applied to six bibliographic databases (Ovid MEDLINE, PubMed, BioMed Central, ProQuest Computing, Web of Knowledge, and ACM Digital Library) including only English-language articles published between 2004 and October 2014. In total, 3932 articles matched the priori search terms and were reviewed by the primary reviewer based on their titles, index terms, and abstracts. The matching articles were then screened by the primary reviewer for inclusion or exclusion based on their abstract, study type, and intervention objectives with respect to the full set of priori inclusion and exclusion criteria; 331 duplicates were identified and removed. A total of 85 articles were included for in-depth review and the remaining 3516 articles were excluded. The primary and secondary reviewer independently reviewed the complete content of the 85 included articles to identify the applied behavioral change theories, clinical guidelines, and assessment tools. Findings and any disagreement between reviewers were resolved by in-depth discussion and through a consolidation process for each of the included articles. The reviewers identified 17 out of 85 interventions (20%) where at least one model, framework, and/or construct of a behavioral change theory were applied. The review identified six clinical guidelines that were applied across 30 of the 85

    Full Text Available Pelvic inflammation has been implicated in the genesis of ovarian cancer. We conducted serologic measurements of Chlamydia trachomatis antibodies as a surrogate marker of chlamydial pelvic inflammatory disease. Women with ovarian cancer (n=521 and population-based controls (n=766 were tested. IgG antibodies to serovar D of chlamydia elementary bodies (EBs were detected using an ELISA assay. The odds of having ovarian cancer among women with the highest titers (≥0.40 OD units were 0.6 (95% CI 0.4–0.9. These data do not support our earlier finding of elevated titers for antibodies to C. trachomatis among women with ovarian cancer.

    Chlamydia trachomatis is the leading cause of preventable blindness and the most common bacterial sexually transmitted infection. Remarkable progress in vaccine research over the past six decades has led to the advancement of novel C. trachomatis vaccine candidates into clinical trials. However, many questions regarding the role of specific cellular populations and molecular mechanisms in protective immunity against human C. trachomatis genital tract infections remain unanswered. Biomarkers of vaccine induced protective immunity are elusive in humans, while a cautionary message on the translatability of data obtained from current animal models has emanated from vaccine research and development efforts against other important human pathogens. In this commentary, we highlight recent advances in Chlamydia vaccine development and discuss their implications in the context of a rational approach to the design of a human C. trachomatis vaccine.

    Little is known about potential harmful effects as a consequence of self-guided internet-based cognitive behaviour therapy (iCBT), such as symptom deterioration rates. Thus, safety concerns remain and hamper the implementation of self-guided iCBT into clinical practice. We aimed to conduct an individual participant data (IPD) meta-analysis to determine the prevalence of clinically significant deterioration (symptom worsening) in adults with depressive symptoms who received self-guided iCBT compared with control conditions. Several socio-demographic, clinical and study-level variables were tested as potential moderators of deterioration. Randomised controlled trials that reported results of self-guided iCBT compared with control conditions in adults with symptoms of depression were selected. Mixed effects models with participants nested within studies were used to examine possible clinically significant deterioration rates. Thirteen out of 16 eligible trials were included in the present IPD meta-analysis. Of the 3805 participants analysed, 7.2% showed clinically significant deterioration (5.8% and 9.1% of participants in the intervention and control groups, respectively). Participants in self-guided iCBT were less likely to deteriorate (OR 0.62, p guided iCBT has a lower rate of negative outcomes on symptoms than control conditions and could be a first step treatment approach for adult depression as well as an alternative to watchful waiting in general practice.

    Elevation of plasma sulfur-containing amino acids (SAAs) is generally associated with higher body mass index (BMI) and unfavorable lipid profiles. It is not known how dietary SAAs relate to these associations in humans. A convenient tool named internet-based dietary questionnaire for Chinese (IDQC) was used to estimate dietary SAAs intake. A total of 936 participants were randomly recruited and asked to complete the IDQC. Furthermore, 90 subjects were randomly selected to perform a subgroup study. The associations between dietary SAAs and prevalence of obesity, lipid profiles, and status of insulin resistance (IR), inflammation and oxidative stress were assessed. Dietary total SAAs and cysteine of overweight/obese participants were significantly higher. Dietary total SAAs and cysteine were positively associated with BMI and waist circumference. Higher dietary total SAAs were associated with higher prevalence of overweight/obesity. Higher dietary total SAAs and cysteine also associated with higher serum triglyceride (total cholesterol), low density lipoprotein, fasting blood glucose, 2 h-postprandial glucose, and homeostasis model assessment of IR. In the subgroup study, positive associations between dietary SAAs and inflammation biomarkers were also observed. Dietary SAAs are associated with higher prevalence of overweight/obesity, unfavorable lipid profiles and status of IR, and inflammation. © 2018 S. Karger AG, Basel.

    Access to evidence-based interventions for common mental health conditions is limited due to geographic distance, scheduling, stigma, and provider availability. Internet-based self-care programs may mitigate these barriers. However, little is known about internet-based self-care program implementation in US health care systems. The objective of this study was to identify determinants of practice for internet-based self-care program use in primary care by eliciting provider and administrator perspectives on internet-based self-care program implementation. The objective was explored through qualitative analysis of semistructured interviews with primary care providers and administrators from the Veterans Health Administration. Participants were identified using a reputation-based snowball design. Interviews focused on identifying determinants of practice for the use of internet-based self-care programs at the point of care in Veterans Health Administration primary care. Qualitative analysis of transcripts was performed using thematic coding. A total of 20 physicians, psychologists, social workers, and nurses participated in interviews. Among this group, internet-based self-care program use was relatively low, but support for the platform was assessed as relatively high. Themes were organized into determinants active at patient and provider levels. Perceived patient-level determinants included literacy, age, internet access, patient expectations, internet-based self-care program fit with patient experiences, interest and motivation, and face-to-face human contact. Perceived provider-level determinants included familiarity with internet-based self-care programs, changes to traditional care delivery, face-to-face human contact, competing demands, and age. This exploration of perspectives on internet-based self-care program implementation among Veterans Health Administration providers and administrators revealed key determinants of practice, which can be used to develop

    Chlamydial abortion in small ruminants is usually associated with Chlamydia abortus infection. Although Chlamydia pecorum has been detected in aborted ruminants and epidemiological data suggests that C. pecorum is abortigenic in these species, published descriptions of lesions in fetuses are lacking. This work describes fetoplacental lesions in a caprine abortion with C. pecorum infection, and further supports the abortigenic role of C. pecorum in ruminants. A 16-month-old Boer goat aborted twin fetuses at ~130 days of gestation. Both fetuses (A and B) and the placenta of fetus A were submitted for postmortem examination and diagnostic workup. At autopsy, the fetuses had moderate anasarca, intermuscular edema in the hindquarters (A), and brachygnathia and palatoschisis (B). In the placenta, the cotyledons were covered by yellow fibrinosuppurative exudate that extended into the adjacent intercotyledonary areas. Histologically, there was severe suppurative and necrotizing placentitis with vasculitis (arteriolitis) and thrombosis, multifocal lymphohistiocytic and neutrophilic hepatitis (A), and fibrinosuppurative enteritis in both fetuses. Chlamydia antigen was detected in the placenta by the direct fluorescent antibody test and in fetal intestines by immunohistochemistry. Nested polymerase chain reaction of DNA extracted from formalin-fixed, paraffin-embedded sections of placenta and intestine amplified 400 bp of the Chlamydia 16S rRNA gene that was sequenced and found to be 99% identical to C. pecorum by BLAST analysis. Other known abortigenic infectious agents were ruled out by specific testing. It is concluded that C. pecorum infection is associated with fetoplacental lesions and sporadic abortion in goats. © 2015 The Author(s).

    In the literature, studies of Chlamydia infection in birds have usually been confined to the search for Chlamydia (C., formerly Chlamydophila) psittaci, so that little is known about the presence of other chlamydial agents. In the present study, cloacal swabs and faeces samples of urban pigeons have been examined by real-time PCR, DNA microarray assays and partial ompA sequencing. Whilst C. psittaci was the predominant chlamydial agent in this pigeon population (75.8% of all Chlamydiaceae positives), the combined use of highly specific and sensitive molecular assays facilitated the detection of atypical serovars of C. psittaci, as well as other species of Chlamydia, such as C. abortus. Detection of C. pecorum and C. trachomatis from an avian host is reported here for the first time. Rather unexpectedly, 19.5% of all Chlamydiaceae-positive cases turned out to be infected with non-classified organisms. The considerable prevalence of these novel agents raises the question of their epidemiological importance and possible role as pathogens. Future surveys in domestic and wild birds will have to take the extended variety of chlamydial organisms into account. Copyright © 2012 Elsevier B.V. All rights reserved.

  3. Characterization of interactions between inclusion membrane proteins from Chlamydia trachomatis

    Full Text Available Chlamydiae are obligate intracellular pathogens of eukaryotes. The bacteria grow in an intracellular vesicle called an inclusion, the membrane of which is heavily modified by chlamydial proteins called Incs (Inclusion membrane proteins. Incs represent 7-10% of the genomes of Chlamydia and, given their localization at the interface between the host and the pathogen, likely play a key role in the development and pathogenesis of the bacterium. However, their functions remain largely unknown. Here, we characterized the interaction properties between various Inc proteins of C. trachomatis, using a bacterial two-hybrid (BACTH method suitable for detecting interactions between integral membrane proteins. To validate this approach, we first examined the oligomerization properties of the well-characterized IncA protein and showed that both the cytoplasmic domain and the transmembrane region independently contribute to IncA oligomerization. We then analyzed a set of Inc proteins and identified novel interactions between these components. Two small Incs, IncF and Ct222, were found here to interact with many other Inc proteins and may thus represent interaction nodes within the inclusion membrane. Our data suggest that the Inc proteins may assemble in the membrane of the inclusion to form specific multi-molecular complexes in an hierarchical and temporal manner. These studies will help to better define the putative functions of the Inc proteins in the infectious process of Chlamydia.

    Anxiety, depression and stress, often co-occurring, are the psychological problems for which university students most often seek help. Moreover there are many distressed students who cannot, or choose not to, access professional help. The present study evaluated the efficacy of an internet-based guided self-help program for moderate anxiety, depression and stress. The program was based on standard cognitive behavior therapy principles and included 5 core modules, some of which involved options for focusing on anxiety and/or depression and/or stress. Trained student coaches provided encouragement and advice about using the program via e-mail or brief weekly phone calls. Sixty-six distressed university students were randomly assigned to either Immediate Access or a 6-week Delayed Access condition. Sixty-one percent of Immediate Access participants completed all 5 core modules, and 80% of all participants completed the second assessment. On the Depression, Anxiety and Stress Scales-21, Immediate Access participants reported significantly greater reductions in depression (ηp(2)=. 07), anxiety (ηp(2)=. 08) and stress (ηp(2)=. 12) in comparison to participants waiting to do the program, and these improvements were maintained at a six month follow-up. The results suggest that the provision of individually-adaptable, internet-based, self-help programs can reduce psychological distress in university students. Copyright © 2013 Elsevier Ltd.

    Full Text Available The mental health of young people is decreasing. It is therefore important to develop early interventions for young people with mental health problems. One previous randomized controlled trial on tailored Internet-based treatment for young adults with minimal therapist guidance has shown promising results for anxiety symptoms. The purpose of this study was to investigate the effects of tailored internet-administered CBT for young adults (16–25 years old with anxiety, depression and possible comorbidity in regular care. Participants were recruited from a youth health care centre (n = 15. Screening consisted of online questionnaires followed by a semi-structured interview. A total of 10 participants completed pre and post measurement. The treatment consisted of individually prescribed CBT text modules with online therapist guidance. All dependent measures improved significantly immediately following treatment and the within-group effect based on pre- to post measurement on the primary outcome measure, the Beck Anxiety Inventory, was d = 1.50, the within-group effect on the secondary outcome measures, Montgomery Åsberg Depression Rating Scale-Self-Rated, Clinical Outcomes in Routine Evaluation and Quality of Life Inventory showed large improvement. Tailored internet-based treatment can be an approach in the treatment of anxiety symptoms and comorbid depressive symptoms in youth care.

    An Internet-based field experiment was conducted to examine potential hiring discrimination based on sexual orientation; specifically, the "first contact" between job applicants and employers was looked at. In response to Internet job postings on CareerBuilder.com®, more than 4,600 resumes were sent to employers in 4 U.S. cities: Philadelphia, Chicago, Dallas, and San Francisco. The resumes varied randomly with regard to gender, implied sexual orientation, and other characteristics. Two hypotheses were tested: first, that employers' response rates vary by the applicants' assumed sexuality; and second, that employers' Response Rates by Sexuality vary by city. Effects of city were controlled for to hold constant any variation in labor market conditions in the 4 cities. Based on employer responses to the applications, it was concluded that there is no evidence that gay men or lesbians are discriminated against in their first encounter with employers, and no significant variation across cities in these encounters was found. Implications of these results for the literature on hiring discrimination based on sexual orientation, the strengths and limitations of the research, and the potential for the Internet-based field experiment design in future studies of discrimination are discussed.

    As adolescents with hemophilia approach adulthood, they are expected to assume responsibility for their disease management. A bilingual (English and French) Internet-based self-management program, "Teens Taking Charge: Managing Hemophilia Online," was developed to support adolescents with hemophilia in this transition. This study explored the usability of the website and resulted in refinement of the prototype. A purposive sample (n=18; age 13-18; mean age 15.5 years) was recruited from two tertiary care centers to assess the usability of the program in English and French. Qualitative observations using a "think aloud" usability testing method and semi-structured interviews were conducted in four iterative cycles, with changes to the prototype made as necessary following each cycle. This study was approved by research ethics boards at each site. Teens responded positively to the content and appearance of the website and felt that it was easy to navigate and understand. The multimedia components (videos, animations, quizzes) were felt to enrich the experience. Changes to the presentation of content and the website user-interface were made after the first, second and third cycles of testing in English. Cycle four did not result in any further changes. Overall, teens found the website to be easy to use. Usability testing identified end-user concerns that informed improvements to the program. Usability testing is a crucial step in the development of Internet-based self-management programs to ensure information is delivered in a manner that is accessible and understood by users.

    Factors and mechanisms determining the differences in virulence and host specificity between the zoonotic agents Chlamydia psittaci and Chlamydia abortus are still largely unknown. In the present study, two strains were compared for their invasiveness, virulence, and capability of eliciting an immune response in chicken embryos. On breeding day 10, embryonated chicken eggs were inoculated with 5 × 10(4) inclusion-forming units. As shown by immunohistochemistry and quantitative real-time PCR, C. psittaci displayed a significantly better capability of disseminating in the chorioallantoic membrane (CAM) and internal organs than C. abortus. The higher infectious potential of C. psittaci in birds was underlined by significantly higher mRNA expression rates of essential chlamydial genes, such as incA, groEL (in CAM, liver, and spleen), cpaf, and ftsW (in CAM). Although the immune responses to both pathogens were similar, C. psittaci elicited higher macrophage numbers and a stronger expression of a subset of immune-related proteins. The data imply that invasiveness of Chlamydia spp. and propagation in the host are not solely dependent on the level of host immune response but, even to a greater extent, on the expression of bacterial factors related to virulence. The fact that C. psittaci has coped far better than C. abortus with the avian embryo's response by upregulating essential genes may be a key to understanding the mechanisms underlying host adaptation and etiopathology.

    We detected Chlamydia pecorum in two koalas ( Phascolarctos cinereus ) from a closed island population in Victoria, Australia, previously free of Chlamydia infection. The ompA and multilocus sequence type were most closely related to published isolates of livestock rather than koala origin, suggesting potential cross-species transmission of C. pecorum .

    Chlamydia infection is known to impact the health of koalas (Phascolarctos cinereus) in New South Wales (NSW) and Queensland, but the clinical significance of Chlamydia infections in Victorian koalas is not well described. We examined the prevalence of Chlamydia infection and assessed associated health parameters in two Victorian koala populations known to be Chlamydia positive. The same testing regimen was applied to a third Victorian population in which Chlamydia had not been detected. We examined 288 koalas and collected samples from the urogenital sinus and conjunctival sacs. Detection and differentiation of Chlamydia species utilized real-time PCR and high-resolution melting curve analysis. Chlamydia pecorum was detected in two populations (prevalences: 25% and 41%, respectively) but only from urogenital sinus swabs. Chlamydia was not detected in the third population. Chlamydia pneumoniae was not detected. Chlamydia pecorum infection was positively associated with wet bottom (indicating chronic urinary tract disease) in one Chlamydia-positive population and with abnormal urogenital ultrasound findings in the other Chlamydia-positive population. The prevalence of wet bottom was similar in all populations (including the Chlamydia-free population), suggesting there is another significant cause (or causes) of wet bottom in Victorian koalas. Ocular disease was not observed. This is the largest study of Chlamydia infection in Victorian koalas, and the results suggest the potential for epidemiologic differences related to Chlamydia infections between Victorian koalas and koalas in Queensland and NSW and also between geographically distinct Victorian populations. Further studies to investigate the genotypes of C. pecorum present in Victorian koalas and to identify additional causes of wet bottom in koalas are indicated.

    Sex-related infections are a global problem. Such infections may lead to acute or chronic diseases. Chlamydia trachomatis is a dangerous and widespread pathogenicity factor that is not sensitive to conventional drugs and has no obvious symptoms. Protein CPAF is leading factor of pathogenesis. This protein inhibits the signaling pathways of host cell and supports long survival of the pathogen in the host cell. The goal of this work was to review general properties of the proteasome Chlamydia protein CPAF, its functions, and role in pathology. The role of protein CPAF in the anti-chlamydia immune reaction is discussed. The prospects of the development of promising anti-chlamydia vaccine, as well as new effective anti-chlamydia drugs are also discussed.

    The humoral immune response to Chlamydia outer membrane protein 2 (Omp2) was studied. Omp2 is a highly genus-conserved structural protein of all Chlamydia species, containing a variable N-terminal fragment. To analyze where the immunogenic parts were localized, seven highly purified truncated...... fusion proteins constituting different regions of the protein were produced (Chlamydia pneumoniae-Omp2aa23-aa93, Chlamydia psittaci-Omp2aa23-aa94, and Chlamydia trachomatis-Omp2aa23-aa84, aa87-aa547, aa23-aa182, aa167-aa434, aa420-aa547). By an enzyme-linked immunosorbent assay with serologically defined...... patient sera, Omp2 was found to be a major immunogen of both C. pneumoniae and C. trachomatis infections (P species-specific anti-Omp2 immunoglobulins were detected....

    Pregnant ewes have been widely used to test vaccines against Chlamydia abortus. However, this model entails many disadvantages such as high economic costs and long periods of pregnancy. The murine model is very useful for specific studies but cannot replace the natural host for the later stages of vaccine evaluation. Therefore, a non-pregnant model of the natural host might be useful for a vaccine trial to select the best vaccine candidates prior to use of the pregnant model. With this aim, two routes of infection were assessed in young non-pregnant sheep, namely, intranasal (IN) and intratracheal (IT). In addition, groups of non-vaccinated sheep and sheep immunised with an inactivated vaccine were established to investigate the suitability of the model for testing vaccines. After the experimental infection, isolation of the microorganism in several organs, with pathological and immunohistochemical analyses, antibody production assessment and investigation by PCR of the presence of chlamydia in the vagina or rectum were carried out. Experimental IT inoculation of C. abortus induced pneumonia in sheep during the first few days post-infection, confirming the suitability of the IT route for testing vaccines in the natural host. The course of infection and the resulting pathological signs were less severe in vaccinated sheep compared with non-vaccinated animals, demonstrating the success of vaccination. IN infection did not produce evident lesions or demonstrate the presence of chlamydial antigen in the lungs and cannot be considered an appropriate model for testing vaccines.

    WHO recommendations for starting and stopping mass antibiotic distributions are based on a clinical sign of trachoma, which is indirectly related to actual infection with the causative agent, Chlamydia trachomatis. This study aimed to understand the effect of SAFE (surgery, antibiotics, facial cleanliness, and environmental improvement) interventions on ocular chlamydia in Amhara, Ethiopia by describing the infection prevalence in a population-based sample of children ages 1-5 years. Population-based trachoma surveys were conducted in all districts of Amhara, from 2011 to 2015 following approximately 5 years of SAFE. Ocular swabs were collected from randomly selected children whose households were included in the surveys to estimate the zonal prevalence of chlamydial infection. The Abbott Realtime PCR assay was used to detect C. trachomatis DNA using the m2000 system. A total of 15,632 samples were collected across the 10 zones of Amhara. The prevalence of chlamydial infection in children ages 1-5 years was 5.7% (95% Confidence Interval: 4.2-7.3), zonal range 1.0% to 18.5%. Chlamydial infection and trachomatous-inflammation intense (TI) among children ages 1-9 were highly correlated at the zonal level, Spearman correlation(r)= 0.93; P<0.001, while chlamydial infection and trachomatous-inflammation follicular (TF) among children ages 1-9 years were moderately correlated, r= 0.57; P=0.084. After 5 years of SAFE there is appreciable ocular chlamydial infection in children ages 1-5 years, indicating that transmission has not been interrupted, and that interventions should continue. The sign TI was highly correlated with chlamydial infection and can be used as a proxy indicator of infection.

    Confinement to an in-patient hospital ward impairs patients' sense of social support and connectedness. Providing the means, through communication technology, for patients to maintain contact with friends and family can potentially improve well-being at the end of life by minimizing social isolation and facilitating social connection. This study aimed to explore the feasibility of introducing internet-based communication and information technologies for in-patients and their families and to describe their experience in using this technology. A cross-sectional survey design was used to describe patient and family member experiences in using internet-based communication technology and health care provider views of using such technology in palliative care. Participants included 13 palliative in-patients, 38 family members, and 14 health care providers. An iPad or a laptop computer with password-protected internet access was loaned to each patient and family member for about two weeks or they used their own electronic devices for the duration of the patient's stay. Quantitative and qualitative data were collected from patients, families, and health care providers to discern how patients and families used the technology, its ease of use and its impact. Descriptive statistics and paired sample t-tests were used to analyze quantitative data; qualitative data were analyzed using constant comparative techniques. Palliative patients and family members used the technology to keep in touch with family and friends, entertain themselves, look up information, or accomplish tasks. Most participants found the technology easy to use and reported that it helped them feel better overall, connected to others and calm. The availability of competent, respectful, and caring technical support personnel was highly valued by patients and families. Health care providers identified that computer technology helped patients and families keep others informed about the patient's condition, enabled

Patients and methods: An Internet-based program was used to teach adaptive ways to cope with depressive symptoms and daily problems. A total of 124 participants who were experiencing at least one stressful event that caused interference in their lives, many of whom had clinically significant depressive symptoms, were randomly assigned into either an intervention group with ICT support (automated mobile phone messages, automated emails, and continued feedback through the program; an intervention group with ICT support plus human support (brief weekly support phone call without clinical content; or a waiting-list control. At pre-, post-, and 12-month follow-up, they completed depression, anxiety, positive and negative effect, and perceived stress measures. Results were analyzed using both intention-to-treat and completers data. The majority were women (67.7%, with a mean age of 35.6 years (standard deviation =9.7. Results: The analysis showed that the two intervention groups improved significantly pre- to posttreatment, compared with the control group. Furthermore, improvements were maintained at the 12-month follow-up. Adherence and satisfaction with the program was high in both conditions. Conclusion: The Internet-based program was effective and well

    In October 2012, a freely available, internet-based cleft simulator was created in partnership between academic, nonprofit, and industry sectors. The purpose of this educational resource was to address global disparities in cleft surgery education. This report assesses demographics, usage, and global effect of our simulator, in its fifth year since inception. Evaluate the global effect, usage, and demographics of an internet-based educational digital simulation cleft surgery software. Simulator modules, available in five languages demonstrate surgical anatomy, markings, detailed procedures, and intraoperative footage to supplement digital animation. Available data regarding number of users, sessions, countries reached, and content access were recorded. Surveys evaluating the demographic characteristics of registered users and simulator use were collected by direct e-mail. The total number of simulator new and active users reached 2865 and 4086 in June 2017, respectively. By June 2017, users from 136 countries had accessed the simulator. From 2015 to 2017, the number of sessions was 11,176 with a monthly average of 399.0 ± 190.0. Developing countries accounted for 35% of sessions and the average session duration was 9.0 ± 7.3 minutes. This yields a total simulator screen time of 100,584 minutes (1676 hours). Most survey respondents were surgeons or trainees (87%) specializing in plastic, maxillofacial, or general surgery (89%). Most users found the simulator to be useful (88%), at least equivalent or more useful than other resources (83%), and used it for teaching (58%). Our internet-based interactive cleft surgery platform reaches its intended target audience, is not restricted by socioeconomic barriers to access, and is judged to be useful by surgeons. More than 4000 active users have been reached since inception. The total screen time over approximately 2 years exceeded 1600 hours. This suggests that future surgical simulators of this kind may be sustainable by

    Difficulties with vaginal penetration can severely affect a woman's desire to have sexual intercourse, her sexual and general well-being, or her partnership. However, treatment opportunities for vaginismus are scarce. To evaluate the efficacy of an internet-based guided self-help intervention for vaginismus in a randomized controlled pilot trial. Seventy-seven women with vaginismus (primary inclusion criterion = no intercourse ≥ 6 months) were randomly assigned to an intervention group (IG) and a waitlist control group (WCG). The intervention consisted of 10 sessions involving psychoeducation, relaxation exercises, sensate focus, and gradual exposure with dilators. Participants received written feedback on completed sessions from an eCoach. The primary outcome was successful sexual intercourse. Secondary outcomes were non-intercourse penetration, fear of coitus, sexual functioning, and dyadic coping. Self-reported assessments were scheduled at baseline, 10 weeks, and 6 months. More participants (10 of 40, 34.48%) in the IG had intercourse compared with those in the WCG (6 of 37, 20.69%) at least once at 10 weeks or 6 months (odds ratio = 2.02). The difference was not significant (χ 2 1  = 1.38, P = .38), but in the IG, there was a significant increase in intercourse penetration from baseline to 6 months (d = 0.65). No such increase was found in the WCG (d = 0.21). There were significant between-group effects concerning non-intercourse penetration (self-insertion of a finger or dilator or insertion by the partner) in favor of the IG. Fear of coitus and dyadic coping significantly decreased in the IG. Overall satisfaction with the training was high. This randomized controlled trial showed promising effects of an internet-based intervention by increasing participants' ability to have intercourse and non-intercourse penetration while experiencing high treatment satisfaction. The WCG also showed improvement, although participants had vaginismus for an average

    Many studies have provided evidence for the effectiveness of Internet-based stand-alone interventions for mental disorders. A newer form of intervention combines the strengths of face-to-face (f2f) and Internet approaches (blended interventions). The aim of this review was to provide an overview of (1) the different formats of blended treatments for adults, (2) the stage of treatment in which these are applied, (3) their objective in combining face-to-face and Internet-based approaches, and (4) their effectiveness. Studies on blended concepts were identified through systematic searches in the MEDLINE, PsycINFO, Cochrane, and PubMed databases. Keywords included terms indicating face-to-face interventions ("inpatient," "outpatient," "face-to-face," or "residential treatment"), which were combined with terms indicating Internet treatment ("internet," "online," or "web") and terms indicating mental disorders ("mental health," "depression," "anxiety," or "substance abuse"). We focused on three of the most common mental disorders (depression, anxiety, and substance abuse). We identified 64 publications describing 44 studies, 27 of which were randomized controlled trials (RCTs). Results suggest that, compared with stand-alone face-to-face therapy, blended therapy may save clinician time, lead to lower dropout rates and greater abstinence rates of patients with substance abuse, or help maintain initially achieved changes within psychotherapy in the long-term effects of inpatient therapy. However, there is a lack of comparative outcome studies investigating the superiority of the outcomes of blended treatments in comparison with classic face-to-face or Internet-based treatments, as well as of studies identifying the optimal ratio of face-to-face and Internet sessions. Several studies have shown that, for common mental health disorders, blended interventions are feasible and can be more effective compared with no treatment controls. However, more RCTs on effectiveness and

    Postpartum weight retention increases lifetime risk of obesity and related morbidity. Few effective interventions exist for multicultural, low-income women. To test whether an internet-based weight loss program in addition to the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC program) for low-income postpartum women could produce greater weight loss than the WIC program alone over 12 months. A 12-month, cluster randomized, assessor-blind, clinical trial enrolling 371 adult postpartum women at 12 clinics in WIC programs from the California central coast between July 2011 and May 2015 with data collection completed in May 2016. Clinics were randomized to the WIC program (standard care group) or the WIC program plus a 12-month primarily internet-based weight loss program (intervention group), including a website with weekly lessons, web diary, instructional videos, computerized feedback, text messages, and monthly face-to-face groups at the WIC clinics. The primary outcome was weight change over 12 months, based on measurements at baseline, 6 months, and 12 months. Secondary outcomes included proportion returning to preconception weight and changes in physical activity and diet. Participants included 371 women (mean age, 28.1 years; Hispanic, 81.6%; mean weight above prepregnancy weight, 7.8 kg; mean months post partum, 5.2 months) randomized to the intervention group (n = 174) or standard care group (n = 197); 89.2% of participants completed the study. The intervention group produced greater mean 12-month weight loss compared with the standard care group (3.2 kg in the intervention group vs 0.9 kg in standard care group, P income postpartum women, an internet-based weight loss program in addition to the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC program) compared with the WIC program alone resulted in a statistically significant greater weight loss over 12 months.

    The Internet has increasingly become an intrinsic part of everyday life, offering countless possibilities for education, services, recreation, and more. In fact, an entire virtual life within the digitalized World Wide Web is possible and common among many Internet users. Today's psychiatrists must therefore incorporate this dimension of human life into clinical practice, to achieve an adequate assessment of the tools and risks available to the patient. We focus on the Internet as a portal for the trade of and access to substances of abuse. We review the legal regulations that may inform care and standards of practice and analyze the difficulties that arise in assessment and monitoring of the current situation. We consider the potential impact of Internet-based narcotics trade on addiction morbidities and the practice of clinical psychiatry, as well as on the potential legal implications that the forensic expert may face.

    Hospitalized palliative patients need to keep in touch with their loved ones. Regular social contact may be especially difficult for individuals on palliative care in-patient units due to the isolating nature of hospital settings. Technology can help mitigate isolation by facilitating social connection. This study aimed to explore the acceptability of introducing internet-based communication and information technologies for patients on a palliative care in-patient unit. In the first phase of the Keep in Touch (KIT) project, a diverse group of key informants were consulted regarding their perspectives on web-based communication on in-patient palliative care units. Participants included palliative patients, family members, direct care providers, communication and information technology experts, and institutional administrators. Data was collected through focus groups, interviews and drop-in consultations, and was analyzed for themes, consensus, and major differences across participant groups. Hospitalized palliative patients and their family members described the challenges of keeping in touch with family and friends. Participants identified numerous examples of ways that communication and information technologies could benefit patients' quality of life and care. Patients and family members saw few drawbacks associated with the use of such technology. While generally supportive, direct care providers were concerned that patient requests for assistance in using the technology would place increased demands on their time. Administrators and IT experts recognized issues such as privacy and costs related to offering these technologies throughout an organization and in the larger health care system. This study affirmed the acceptability of offering internet-based communication and information technologies on palliative care in-patient units. It provides the foundation for trialing these technologies on a palliative in-patient unit. Further study is needed to confirm the

  14. Group versus Internet-based cognitive-behavioral therapy for procrastination: Study protocol for a randomized controlled trial

    2014-04-01

    Full Text Available Procrastination is defined as a voluntarily delay of an intended course of action despite expecting to be worse-off for the delay, and is considered a persistent behavior pattern that can result in major psychological suffering. About one-fifth of the adult population and half of the student population are presumed having substantial difficulties due to recurrent procrastination in their everyday lives. However, chronic and severe procrastinators seldom receive adequate care due to preconceptions and the lack of understanding regarding procrastination and the treatment interventions that are assumed beneficial. Cognitive-behavioral therapy is often deemed a treatment of choice, although the evidence supporting its use is scarce, and only one randomized controlled trial has been performed. The primary aim of the proposed study is therefore to test the efficacy of cognitive-behavioral therapy delivered as either a group intervention or via the Internet. Participants will consist of students recruited through the Student Health Centre at Karolinska Institutet. A randomized controlled trial with a sample size of 100 participants divided into blocks of thirty will be used, comparing an eight-week Internet-based cognitive-behavioral therapy intervention, and an eight-week group cognitive-behavioral therapy based intervention. It is believed that the proposed study will result in two important findings. First, different treatment interventions in cognitive-behavioral therapy are assumed to be helpful for people suffering from problems caused by procrastination. Second, both an Internet-based cognitive-behavioral therapy intervention and a group intervention are presumed suitable for administering treatment for procrastination, which is considered important as the availability of adequate care is limited, particularly among students. The proposed study will increase the knowledge regarding the efficacy of different treatments of procrastination, as well

    To understand current awareness of, and views on, treatment of alcohol dependence in Japan. (a) Nationwide internet-based survey of 520 individuals, consisting of 52 diagnosed alcohol-dependent (AD) persons, 154 potentially alcohol-dependent (ADP) persons, 104 family members and 106 friends/colleagues of AD persons, and 104 general individuals, derived from a consumer panel where the response rate was 64.3%. We enquired into awareness about the treatment of alcohol dependence and patient pathways through the healthcare network. (b) Nationwide internet-based survey of physicians (response rate 10.1% (2395/23,695) to ask 200 physicians about their management of alcohol use disorders). We deduced that 10% of alcohol-dependent Japanese persons had ever been diagnosed with alcohol dependence, with only 3% ever treated. Regarding putative treatment goals, 20-25% of the AD and ADP persons would prefer to attempt to abstain, while 60-75% preferred 'reduced drinking.' A half of the responding physicians considered abstinence as the primary treatment goal in alcohol dependence, while 76% considered reduced drinking as an acceptable goal. AD and ADP persons in Japan have low 'disease awareness' defined as 'understanding of signs, symptoms and consequences of alcohol use disorders,' which is in line with the overseas situation. The Japanese drinking culture and stigma toward alcohol dependence may contribute to such low disease awareness and current challenging treatment environment. While abstinence remains the preferred treatment goal among physicians, reduced drinking seems to be an acceptable alternative treatment goal to many persons and physicians in Japan. © The Author 2014.

    A large proportion of individuals with alcohol problems do not seek psychological treatment, but access to such treatment could potentially be increased by delivering it over the Internet. Cognitive behavior therapy (CBT) is widely recognized as one of the psychological treatments for alcohol problems for which evidence is most robust. This study evaluated a new, therapist-guided internet-based CBT program (entitled ePlus) for individuals with alcohol use disorders. Participants in the study (n = 13) were recruited through an alcohol self-help web site ( www.alkoholhjalpen.se ) and, after initial internet screening, were diagnostically assessed by telephone. Eligible participants were offered access to the therapist-guided 12-week program. The main outcomes were treatment usage data (module completion, treatment satisfaction) as well as glasses of alcohol consumed the preceding week, measured with the self-rated Timeline Followback (TLFB). Participant data were collected at screening (T0), immediately pre-treatment (T1), post-treatment (T2) and 3 months post-treatment (T3). Most participants were active throughout the treatment and found it highly acceptable. Significant reductions in alcohol consumption with a large within-group effect size were found at the three-month follow-up. Secondary outcome measures of craving and self-efficacy, as well as depression and quality of life, also showed significant improvements with moderate to large within-group effect sizes. Therapist-guided internet-based CBT may be a feasible and effective alternative for people with alcohol use disorders. In view of the high acceptability and the large within-group effect sizes found in this small pilot, a randomized controlled trial investigating treatment efficacy is warranted.

    Clinicians in developing countries have had limited access to continuing education (CE) outside major cities, and CE strategies have had limited impact on sustainable change in performance. New educational tools could improve CE accessibility and effectiveness. The objective of this study was to evaluate an interactive Internet-based CE course on Sexually Transmitted Diseases (STDs) management for clinicians in Peru. Participants included physicians and midwives in private practice drawn from a census of 10 Peruvian cities. The CE included a three-hour workshop for improving Internet skills, followed by a 22-hour online course on STD-syndrome-management, with subsequent educational support. The course used case-based clinical vignettes tailored to local STD problems. Knowledge and reported practices on STD management were assessed before, immediately after and at four months after completion of the course. Statistical analysis included parametric tests-linear regression multivariate analysis, paired t-test and repeated measures ANOVA using SPSS 14.0. Of 1,071 eligible clinicians, 510 agreed to participate, as did an additional 132 public sector clinicians. Of these 642 participants, 619 (96.4%) completed the course, and 596 (96.3%) took the four-month follow-up evaluation.

    2011-11-01

    Full Text Available Background: Injured trauma victims are at risk of developing Posttraumatic Stress Disorder (PTSD and other post-trauma psychopathology. So far, interventions using cognitive behavioral techniques (CBT have proven most efficacious in treating early PTSD in highly symptomatic individuals. No early intervention for the prevention of PTSD for all victims has yet proven effective. In the acute psychosocial care for trauma victims, there is a clear need for easily applicable, accessible, cost-efficient early interventions. Objective: To describe the design of a randomized controlled trial (RCT evaluating the effectiveness of a brief Internet-based early intervention that incorporates CBT techniques with the aim of reducing acute psychological distress and preventing long-term PTSD symptoms in injured trauma victims. Method: In a two armed RCT, 300 injured trauma victims from two Level-1 trauma centers in Amsterdam, the Netherlands, will be assigned to an intervention or a control group. Inclusion criteria are: being 18 years of age or older, having experienced a traumatic event according to the diagnostic criteria of the DSM-IV and understanding the Dutch language. The intervention group will be given access to the intervention's website (www.traumatips.nl, and are specifically requested to login within the first month postinjury. The primary clinical study outcome is PTSD symptom severity. Secondary outcomes include symptoms of depression and anxiety, quality of life, and social support. In addition, a cost-effectiveness analysis of the intervention will be performed. Data are collected at one week post-injury, prior to first login (baseline, and at 1, 3, 6 and 12 months. Analyses will be on an intention-to-treat basis. Discussion: The results will provide more insight into the effects of preventive interventions in general, and Internet-based early interventions specifically, on acute stress reactions and PTSD, in an injured population, during the

    Full Text Available Background: Tinnitus is a common medical symptom that can affect an individual’s emotional and functional quality of life. Psychological therapies are acknowledged as beneficial to people with tinnitus, however, they are not always readily accessible. With their global reach, internet-based interventions have the potential to reduce the disparity in access to psychological support which people with tinnitus currently experience. Aim: This research will explore users’ reactions to and interactions with the Tinnitus E-Programme, an internet-based intervention for the self-management of tinnitus that is currently available online. Methods: Ten people with tinnitus have completed the programme and taken part in a semi-structured interview to date. Participants also completed a relaxation log to explore how well they were able to implement the skills they learnt during the programme in their everyday lives. The interview data will be presented. Results: Thematic analysis revealed that, overall, the programme was highly acceptable to its target population. Users valued the provided education about tinnitus and its management, relaxation skills training and cognitive restructuring training. Usage of the tools to self-monitor levels of tinnitus distress was variable and few people reported joining or participating in the online support group. Participants appreciated being able to work flexibly with the programme and engaging with the materials ‘offline’. Usability issues meant that some essential programme components were often missed. Conclusions: Findings suggest that the programme offers an acceptable form of tinnitus management for its target group. However, this work also highlighted some key opportunities to improve the programme. In future work, these qualitative findings will be triangulated with the relaxation log data and the findings from a parallel online survey with past users who have used the programme in the real

    2013-01-01

    Background As adolescents with hemophilia approach adulthood, they are expected to assume responsibility for their disease management. A bilingual (English and French) Internet-based self-management program, “Teens Taking Charge: Managing Hemophilia Online,” was developed to support adolescents with hemophilia in this transition. This study explored the usability of the website and resulted in refinement of the prototype. Methods A purposive sample (n=18; age 13–18; mean age 15.5 years) was recruited from two tertiary care centers to assess the usability of the program in English and French. Qualitative observations using a “think aloud” usability testing method and semi-structured interviews were conducted in four iterative cycles, with changes to the prototype made as necessary following each cycle. This study was approved by research ethics boards at each site. Results Teens responded positively to the content and appearance of the website and felt that it was easy to navigate and understand. The multimedia components (videos, animations, quizzes) were felt to enrich the experience. Changes to the presentation of content and the website user-interface were made after the first, second and third cycles of testing in English. Cycle four did not result in any further changes. Conclusions Overall, teens found the website to be easy to use. Usability testing identified end-user concerns that informed improvements to the program. Usability testing is a crucial step in the development of Internet-based self-management programs to ensure information is delivered in a manner that is accessible and understood by users.

    Many older spouse caregivers are tied to the home by their caring duties and feel isolated. The values of supporting older caregivers are well known. In rural areas with long distances and decline in essential services, attending caregiver support groups can be difficult. Using Internet-based services can provide an opportunity for rural caregivers to participate in caregiver support, regardless of geographical distances and without the need for physical presence. This study aimed to explore how Internet-based caregiver support may influence the experience of isolation among older spouse caregivers in rural areas. An intervention study where 63 older rural caregivers received an Internet-based caregiver support service. A qualitative interview study based on 31 interviews with open-ended questions, analysed using latent content analysis. Two themes represent the findings from the study: Expanding the concept of place and Developing networks. Even though participants still spent their days in the house, they experienced that daily life was being spent in a variety of places, both physically, virtually and emotionally. The Internet-based support service provided them with a tool to reconnect with family and develop new friends. Internet-based caregiver support may reduce the experience of isolation for spouse caregivers in rural areas. Nurses played a crucial part in the development, by encouraging, educating and inspiring caregivers and supporting their independence. Internet-based services ought to be an option for caregiver support in rural areas as it may reduce feelings of isolation for older spouse caregivers. © 2014 John Wiley & Sons Ltd.

    Chlamydia trachomatis (CT) is the most prevalent cause of sexually transmitted diseases. Although the prevalence of chlamydial infection is similar in men and women, current research and screening are still focused on women, who develop the most severe complications, leaving the study of male genital tract (MGT) infection underrated. Herein, we reviewed the literature on genital CT infection with special focus on the MGT. Data indicate that CT certainly infects different parts of the MGT such as the urethra, seminal vesicles, prostate, epididymis and testis. However, whether or not CT infection has detrimental effects on male fertility is still controversial. The most important features of CT infection are its chronic nature and the presence of a mild inflammation that remains subclinical in most individuals. Chlamydia antigens and pathogen recognition receptors (PRR), expressed on epithelial cells and immune cells from the MGT, have been studied in the last years. Toll-like receptor (TLR) expression has been observed in the testis, epididymis, prostate and vas deferens. It has been demonstrated that recognition of chlamydial antigens is associated with TLR2, TLR4, and possibly, other PRRs. CT recognition by PRRs induces a local production of cytokines/chemokines, which, in turn, provoke chronic inflammation that might evolve in the onset of an autoimmune process in genetically susceptible individuals. Understanding local immune response along the MGT, as well as the crosstalk between resident leukocytes, epithelial, and stromal cells, would be crucial in inducing a protective immunity, thus adding to the design of new therapeutic approaches to a Chlamydia vaccine.

    A historical review is provided of the various methods used for half a century to differentiate and type Chlamydia trachomatis strains. Typing of C. trachomatis is an important tool for revealing transmission patterns in sexual networks, and enabling association with clinical manifestations......, insufficient epidemiological resolution is achieved by characterization of both MOMP and omp1. This calls for new high-resolution genotyping methods applying for example a multilocus variable number tandem repeat assay (MLVA) or multilocus sequence typing (MLST).

    Reproductive disease was investigated in Iberian pigs on an extensive farrow-to-finish farm in the southwest of Spain. Chlamydia abortus was isolated in cell culture and C. abortus-specific PCR products were detected in placental and fetal tissues. In one batch of 14 sows, the percentage of sera positive for C. abortus specific antibodies increased from 35.7% to 85.7% in the period of 2 weeks following abortion. C. abortus may play a role in abortion in extensively reared Iberian sows. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Objectives The objective of this project was to determine whether intervention mapping is a suitable strategy for developing an Internet- and text message-based smoking cessation intervention. Method We used the Intervention Mapping framework for planning health promotion programs. After a needs assessment, we identified important changeable determinants of cessation behavior, specified objectives for the intervention, selected theoretical methods for meeting our objectives, and operationalized change methods into practical intervention strategies. Results We found that "social cognitive theory," the "transtheoretical model/stages of change," "self-regulation theory," and "appreciative inquiry" were relevant theories for smoking cessation interventions. From these theories, we selected modeling/behavioral journalism, feedback, planning coping responses/if-then statements, gain frame/positive imaging, consciousness-raising, helping relationships, stimulus control, and goal-setting as suitable methods for an Internet- and text-based adult smoking cessation program. Furthermore, we identified computer tailoring as a useful strategy for adapting the intervention to individual users. Conclusion The Intervention Mapping method, with a clear link between behavioral goals, theoretical methods, and practical strategies and materials, proved useful for systematic development of a digital smoking cessation intervention for adults. © 2016 Society for Public Health Education.

    Technological advances have sparked the development of computer- and smartphone-based self-help programs for depressed people, but these programs' efficacy is uncertain. This randomized controlled trial evaluated an intervention called SuperBetter (SB), which is accessed via smartphone and/or the SB Web site. Online, we recruited 283 adult iPhone(®) (Apple, Cupertino, CA) users with significant depression symptoms according to the Center for Epidemiological Studies Depression questionnaire (CES-D). They were randomly assigned to one of three conditions: (a) a version of SB using cognitive-behavioral therapy and positive psychotherapy strategies to target depression (CBT-PPT SB); (b) a general SB version focused on self-esteem and acceptance (General SB); or (c) a waiting list control group (WL). The two SB groups were instructed to use SB for 10 minutes daily for 1 month. All participants completed psychological distress and well-being measures online every 2 weeks through follow-up. An intent-to-treat analysis was conducted using hierarchical linear modeling. As hypothesized, SB participants achieved greater reductions in CES-D scores than WL participants by posttest (Cohen's d=0.67) and by follow-up (d=1.05). Contrary to prediction, CBT-PPT SB did not perform better than General SB; both versions of SB were more effective than the WL control. Differences between SB versions favored General SB but were not statistically significant. These large effect sizes should be interpreted cautiously in light of high attrition rates and the motivated, self-selected sample. Nonetheless, smartphone-based/Internet-based self-help may play an important role in treating depression.

    Full Text Available As points of interest (POIon the internet, exists widely incomplete addresses and inconsistent literal expressions, a fast standardization processing method of network POIs address information based on spatial constraints was proposed. Based on the model of the extensible address expression, first of all, address information of POI was segmented and extracted. Address elements are updated by means of matching with the address tree layer by layer. Then, by defining four types of positional relations, corresponding set are selected from standard POI library as candidate for enrichment and amendment of non-standard address. At last, the fast standardized processing of POI address information was achieved with the help of backtracking address elements with minimum granularity. Experiments in this paper proved that the standardization processing of an address can be realized by means of this method with higher accuracy in order to build the address database.

    Vacuolated amniotic epithelium with lipid droplets in gastroschisis placentas is an unusual finding. Mass spectrometry of lipid droplets identified triglycerides, ester-linked to an unusual pattern of fatty acids. We hypothesize that these findings result from a Chlamydia trachomatis infection during the periconceptional period. The rising incidence of chlamydia infections has paralleled the increasing prevalence of gastroschisis among women less than 25 years of age. Histologically, young women are at greatest risk for a chlamydia infection due to their immature columnar epithelium, the preferential site for attachment of Chlamydia trachomatis infectious particle (elementary body). Chlamydia trachomatis survive in an inclusion, relying on its host to acquire essential nutrients, amino acids, and nucleotides for survival and replication. If essential nutrients are not available, the bacteria cannot replicate and may be trafficked to the lysosome for degradation or remain quiescent, within the inclusion, subverting innate immunologic clearance. Chlamydiae synthesize several lipids (phosphatidylethanolamine, phosphatidylserine, and phosphoatidylglycerol); however, their lipid content reveal eukaryotic lipids (sphingomyelin, cholesterol, phosphatidylcholine, and phosphatidylinositol), evidence that chlamydiae "hijack" host lipids for expansion and replication. The abnormal amniotic epithelial findings are supported by experimental evidence of the trafficking of host lipids into the chlamydiae inclusion. If not lethal, what harm will elementary bodies inflict to the developing embryo? Do these women have a greater pro-inflammatory response to an environmental exposure, whether cigarette smoking, change in partner, or a pathogen? Testing the hypothesis that Chlamydia trachomatis is responsible for amniotic epithelium vacuoles will be a critical first step.

    Chlamydia infections are common in both men and women, are often asymptomatic and can cause serious complications. Repeat testing in high-risk groups is therefore indicated. In the Netherlands, guidelines on repeat chlamydia testing differ between testing facilities, and knowledge on repeat testing behaviour is limited. Here, we analyse the current repeat testing behaviour of heterosexual STI clinic visitors, and aim to identify groups for which repeat testing advice could be advantageous. Longitudinal surveillance data from all Dutch STI outpatient clinics were used, which included all STI clinic consultations carried out among heterosexual men and women between June 2014 and December 2015. Repeat testing was defined as returning to the same STI clinic between 35 days and 12 months after initial consultation. We calculated chlamydia positivity at repeat test stratified by initial test result and time between consultations. Logistic regression analyses were used to identify predictors of repeat testing, and predictors of having a chlamydia positive repeat test. In total, 140,486 consultations in 75,487 women and 46,286 men were available for analyses. Overall, 15.4% of women and 11.1% of men returned to the STI clinic within the study period. Highest chlamydia positivity at repeat test was seen 3-5 months after initial positive test. Among both women and men, repeat testing was associated with non-Western ethnicity, having had more than two sex partners in the past 6 months, reporting STI symptoms, having a history of STI, and having a chlamydia positive initial test. Among repeat testers, chlamydia positive repeat test was most strongly associated with younger age, followed by a chlamydia positive initial test. Repeat testing most often resulted in a positive test result among young heterosexuals (<25) and heterosexuals of any age with a chlamydia infection at the initial consultation. Further efforts are needed to determine optimal repeat testing strategies.

    Full Text Available Brandie D Taylor, Catherine L HaggertyUniversity of Pittsburgh, Department of Epidemiology, Pittsburgh, PA, USAAbstract: Chlamydia trachomatis is a prevalent sexually transmitted infection that can lead to serious reproductive morbidity. Management and control of C. trachomatis is a challenge, largely due to its asymptomatic nature and our incomplete understanding of its natural history. Although chlamydia screening programs have been implemented worldwide, several countries have observed increasing rates of reported chlamydia cases. We reviewed the literature relating to the long-term complications of C. trachomatis, as well as screening strategies, treatment, and prevention strategies for reducing chlamydia in the population. Articles from 1950–2010 were identified through a Medline search using the keyword “Chlamydia trachomatis” combined with “screening”, “pelvic inflammatory disease”, “endometritis”, “salpingitis”, “infertility”, "ectopic pregnancy”, “urethritis”, “epididymitis”, “proctitis”, “prostatitis”, “reinfection”, “cost-effectiveness”, “treatment”, “vaccines”, or “prevention”. Progression of C. trachomatis varies, and recurrent infections are common. Currently, there is limited evidence on the effectiveness of chlamydia screening. Higher quality studies are needed to determine the efficacy of more frequent screening, on a broader range of sequelae, including infertility and ectopic pregnancy, in addition to pelvic inflammatory disease. Studies should focus on delineating the natural history of recurrent infections, paying particular attention to treatment failures. Furthermore, alternatives to screening, such as vaccines, should continue to be explored.Keywords: Chlamydia trachomatis, sexually transmitted disease, chlamydia screening, chlamydia treatment

  16. Chlamydiae in febrile children with respiratory tract symptoms and age-matched controls, Ghana

    Full Text Available Members of the Chlamydiales order are obligate intracellular pathogens causing acute and chronic infectious diseases. Chlamydiaceae are established agents of community- and zoonotically acquired respiratory tract infections, and emerging pathogens among the Chlamydia-related bacteria have been implicated in airway infections. The role of both in airway infections in Africa is underexplored. We performed a case -control study on the prevalence of Chlamydiaceae and Chlamydia-related emerging pathogens in children with febrile respiratory tract infections in West Africa, Ghana. Using a pan-Chlamydiales broad-range real-time PCR, we detected chlamydial DNA in 11 (1.9% of 572 hospitalized febrile children with respiratory tract symptoms and in 24 (4.3% of 560 asymptomatic age-matched controls (p 0.03. Chlamydiaceae were found to be common among both symptomatic and healthy Ghanaian children, with Chlamydia pneumoniae being the most prevalent species. Parachlamydiaceae were detected in two children without symptoms but not in the symptomatic group. We identified neither Chlamydia psittaci nor Simkania negevensis but a member of a new chlamydial family that shared 90.2% sequence identity with the 16S rRNA gene of the zoonotic pathogen Chlamydia pecorum. In addition, we found a new Chlamydia-related species that belonged to a novel family sharing 91.3% 16S rRNA sequence identity with Candidatus Syngnamydia venezia. The prevalence and spectrum of chlamydial species differed from previous results obtained from children of other geographic regions and our study indicates that both, Chlamydiaceae and Chlamydia-related bacteria, are not clearly linked to clinical symptoms in Ghanaian children.

    Lawrence Livermore National Laboratories` Zephyr System provides a showcase for the ways in which emerging technologies can help streamline procurement processes and improve the coordination between participants in engineering projects by allowing collaboration in ways that have not been possible before. The project also shows the success of a highly pragmatic approach that was initiated by the end user community, and that intentionally covered standard situations, rather than aiming at also automating the exceptions. By helping push purchasing responsibilities down to the end user, thereby greatly reducing the involvement of the purchasing department in operational activities, it was possible to streamline the process significantly resulting in time savings of up to 90%, major cost reductions, and improved quality. Left with less day-to- day purchasing operations, the purchasing department has more time for strategic tasks such as selecting and pre-qualifying new suppliers, negotiating blanket orders, or implementing new procurement systems. The case shows once more that the use of information technologies can result in major benefits when aligned with organizational adjustments.

    Cervico vaginal smears of women with uterine carcinoma treated with radiotherapy are analyzed in the present work. A series of such smears showed morphological changes suggestive of Chlamydia infection with the Papanicolaou stain. Confirmation of the presence of such agent was done using an avidin-biotin peroxidase technique. A higher prevalence of Chlamydia in the group of patients with carcinoma of the uterus treated with irradiation than in the population without ionizing treatment was verified. The presence of cells with radiotherapic changes infected by Chlamydia is a new finding in cytology. (author)

    Semen specimens from 21 men with urethral infection with Chlamydia trachomatis were tested for the presence of the organism before and after cryopreservation for 3 weeks of storage at -196 degrees C. Five specimens were chlamydia-positive before preservation and four of them were still positive...... after storage when examined by enzyme immunoassay (Chlamydiazyme). When examined by cell culture, four proved chlamydia- positive before storage and two afterwards. The results indicate that testing for C. trachomatis has to be performed from the urethra of all donors of semen used for artificial...

    Full Text Available Background: Urogenital infection caused by Chlamydia trachomatis (CT is among more common curable sexually transmitted diseases (STD in Slovenia; however, the data on the prevalence of asymptomatic infections are insufficient. The purpose of the study was to determine the prevalence of asymptomatic chlamydia infection among male and female young adults in various Slovenian urban environments and to determine the risk factors for the infection.Methods: The study took place between October 15 and November 15 2004 in selected medical centres in Ljubljana, Maribor and Izola. Subjects were volunteers and were sexually active healthy males and females who appeared to be healthy and were aged between 18 and 35. All subjects gave consent to participation in the study. All participants filled in an anonymous questionnaire which included questions on education, sexual behaviour patterns, use of contraceptives and contraceptive methods and history of STDs. The presence of CT in urine samples was determined by the nucleic acid amplification test PCR. All positive subjects were appropriately treated. Significant risk factors were determined by logistic regression.Results: 2027 volunteers participated in the study. They gave a urine sample and filled in the questionnaire. The prevalence of chlamydia infection was 5.8 %. Age analysis showed a 6.5 % prevalence among subjects under 25 years of age and, among subjects above 25, 4.8 %. Both groups revealed similarities in sexual behaviour patterns and use of barrier contraceptives which was 10.9 % in younger and 9.1 % in older participants. Independent factors related to the asymptomatic chlamydia infection were shown to be the number of sexual partners in the past (p = 0.008, more than one sexual partner in the last three months (p = 0.000 and improper use of condoms (p = 0.032.Conclusions: Relatively high prevalence of chlamydia infection among asymptomatic participants demonstrates that the problem is
