    The effectiveness of the influenza vaccine used in the 2001-2002 influenza season in Japan was investigated in a large-scale, geographically widely distributed, Internet-based study. Data were collected from 8841 of 9902 subjects registered by 38 clinics prior to the start of influenza season. Subjects were categorized into three groups by vaccination regimen: unvaccinated, vaccinated once, and vaccinated twice. Efficacy was also analyzed for three age groups: 0-15, 16-64, and 65-104 years. Influenza-like illness (ILI) was diagnosed according to Ministry of Health (MWH, Labor and Welfare in Japan) criteria. Laboratory-confirmed influenza cases were analyzed separately. The respective vaccine efficacy in the 0-15 years group for the one- and two-dose regimens was 67.6 and 84.5% for ILI and 54.0 and 79.8% for laboratory-confirmed influenza. Influenza vaccination was also shown to be effective in subjects 16-64 years. Vaccine effectiveness was not able to be determined for the over 65 years group, probably due to an insufficient number of infected patients. These results suggest that influenza vaccination is effective for children and adults and that a two-dose regimen is superior to a single dose in children 0-15 years.

The primary objective of this study was to investigate the rate of referrals and returning medical reports between optometrists and health care professionals in Norway. The secondary objectives were to investigate the conformity of diagnoses in referrals and medical reports, the extent of optometric follow-up examinations and the use of ophthalmic diagnostic drugs in optometric practice.Materials and methods: This study is an ongoing prospective electronic survey administered on the Internet between November 2014 and December 2017. Optometrists in private optometric practice are eligible. Participants register data for up to 1 year, including examinations and the use of ophthalmic diagnostic drugs; referrals, including International Classification of Primary Care, second edition (ICPC-2 codes; medical reports, including the ICD-10 codes; and optometric follow-up enquiries. Analysis of agreement between referred and diagnosed conditions was made possible by encoding patients’ ID.Results: Seventeen months into the study, 67 optometrists were included (Female: 60%, mean age: 41 years.. There were 49,510 registered examinations (60% general, 28% contact lens, 12% auxiliary. Diagnostic drugs were used in 4% of these and in 14% of the examinations that resulted in a referral. There were 1,779 referrals (97% to ophthalmologists. Top three diagnoses were cataract (36%, glaucoma (11%, and age-related macular degeneration (7%. There were 1,036 returned medical reports, of which 76% could be linked with registered referrals. Diagnostic agreement was observed in 80% of the cases (74% for

    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.

    Internet-based data collection relies on well-designed and validated questionnaires. The theory behind designing and validating questionnaires is well described, but few practical examples of how to approach validation are available in the literature. We aimed to validate data collected in an ongoing Internet-based longitudinal health study through direct visits to participants and recall of their health records. We demonstrate that despite extensive pre-planning, social desirability can still affect data in unexpected ways and that anticipation of poor quality data may be confounded by positive validation. Dogslife is a large-scale, Web-based longitudinal study of canine health, in which owners of Labrador Retrievers were recruited and questioned at regular intervals about the lifestyle and health of their dogs using an Internet-based questionnaire. The Dogslife questionnaire predominantly consists of closed-answer questions. In our work, two separate validation methodologies were used: (1) direct interviews with 43 participants during visits to their households and (2) comparison of owner-entered health reports with 139 historical health records. Our results indicate that user-derived measures should not be regarded as a single category; instead, each measurement should be considered separately as each presents its own challenge to participants. We recommend trying to ascertain the extent of recall decay within a study and, if necessary, using this to guide data collection timepoints and analyses. Finally, we recommend that multiple methods of communication facilitate validation studies and aid cohort engagement. Our study highlighted how the theory underpinning online questionnaire design and validation translates into practical data issues when applied to Internet-based studies. Validation should be regarded as an extension of questionnaire design, and that validation work should commence as soon as sufficient data are available. We believe that validation is a

    With its ever-growing penetration of remote regions of the world, the Internet provides great opportunity for conducting research. Beyond clear advantages such as increased cost-effectiveness and efficiency in collecting large samples, Internet-based research has proven particularly useful in reaching hidden or marginalized populations who engage in illegal or deviant behaviors. However, this new medium for research raises important and complex legal, ethical, and methodological/technological issues that researchers must address, particularly when studying undetected criminal behaviors. The current paper chronicles various issues that were encountered in the implementation of an active Internet-based pilot research study of child pornography (CP) users. Moreover, this study was undertaken to address a critical gap in the existing research on CP offending, which has to date primarily focused on incarcerated or convicted samples. The Internet provides the optimal medium for studying community populations of CP users, given that it has become the primary market for CP distribution. This paper is designed to serve as a guide for researchers interested in conducting Internet-based research studies on criminal and sexually deviant populations, particularly CP offenders. Several recommendations are offered based on our own experiences in the implementation of this study. Copyright 2009 John Wiley & Sons, Ltd.

    Background 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. Objective To report on our experience with Internet-based recruitment to an online depression prevention intervention and pass on lessons we learned. Methods 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. Results 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. Conclusions 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. Trial Registration ACTRN

    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.

    This article evaluates an Internet-based early intervention combining online cognitive-behavioral therapy (CBT) with electronic peer-to-peer support intended to promote mental health and well-being among combat veterans. We conducted a phase 1 clinical trial of 50 Iraq and Afghanistan veterans using a pre and post single-arm design. We evaluated feasibility and changes in mental health symptoms (depression and posttraumatic stress disorder [PTSD]), functional status, and attitudes toward treatment seeking at baseline and weeks 4, 8, and 12. A diverse group of veterans was enrolled (26% ethnic minority, 90% male, 66% with income <$30,000/year, 88% with no prior treatment for depression). Participants completed a mean of 4 of 6 lessons (standard deviation = 2.54). From baseline to week 12, there were significant declines in the Center for Epidemiologic Studies-Depression scale score (effect size [ES] = 0.41) and PTSD Checklist-Military version score (ES = 0.53). There were significant improvements in willingness to accept diagnosis (ES = 1.08) and perceived social norms and stigma regarding friends (ES = 1.51). Although lack of a control group is a limitation, the Internet-based program combining CBT-based coping skills training and peer-to-peer support demonstrated potential feasibility and evidenced benefit in symptom remediation for depression and PTSD.

    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.

    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.

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. 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.

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

    2015-09-01

    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.

    2016-01-01

    Older adults are at risk for greater chronic stress and cognitive decline. Training in mindfulness meditation (MM) may help reduce stress and, thus, cognitive decline in older adults, but little research has explored that hypothesis. The current study's primary aim was to evaluate the feasibility and acceptability for use by older adults of the Internet Mindfulness Meditation Intervention (IMMI), a program that had been developed by the research team, as well as of an Internet-based health-and-wellness education program, the control. The secondary aim was to collect preliminary pre- and postintervention data on mood and cognitive function. The study was a randomized, controlled trial (RCT), a pilot study, with participants randomized either to the meditation group or the education group. Participants obtained access to the programs from their homes, and the baseline and endpoint assessments occurred in their homes as well. Older adults aged 65-90 y were recruited from the Portland, OR, metropolitan area. Twenty-one people enrolled in the study. Participants in both groups took part in a 1-h online session each week for 6 wk, with 30 min of daily home practice. Feasibility and acceptability were assessed through measures of adherence to the protocol and a client satisfaction questionnaire. Mood and cognitive outcomes were also evaluated before and after the interventions. Sixteen participants completed the study, 8 in each group, and 5 dropped out, for a 76% completion rate. Participants' mean age was 76.2 y; 88% were Caucasian, and 50% were female. Acceptability was high for the interventions, based on above-average scores on the client satisfaction questionnaire. The IMMI participants completed (1) 4.25 ± 2.4 sessions, with a range of 0-6; (2) 604 ± 506 home-practice minutes, with a range 0-1432; and (3) 21.3 ± 15.5 d of practice, with a range of 0-46.

    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 prevalence of depression is high and results in huge costs for society. Internet-based cognitive behavioural treatment (ICBT) has been suggested for use in primary care and has been shown to be more effective when combined with human support. However, non-completion rates remain a challenge. Current recommendations state that steps to improve persistence with ICBT should be determined and the impact of therapist support on persistence explored. A few earlier studies have explored motivations to persist with ICBT without face-to-face therapist support. The present study explored the motivation to persist as experienced by a group of patients who sought help in primary care and used "blended care", i.e. ICBT supported by short face-to-face consultations. To elucidate motivation in an everyday context and the meaning of patients' experiences we chose a phenomenological hermeneutical approach. We interviewed participants in the intervention group of a randomized controlled trial that evaluated the efficacy of an ICBT programme called MoodGYM, an eHealth intervention used to treat depression. Fourteen participants, both completers and non-completers, went through individual, semi-structured interviews after they ended their treatment. Hope of recovery and a desire to gain control of one's life were identified as intrinsic motivators. The feeling of being able to freely choose how, when and where to complete the ICBT modules was identified as an important supporting condition and satisfied the participants' need for autonomy. Furthermore, the importance of a sense of belonging towards partners, friends or family was essential for motivation as was the ability to identify with ICBT content. Another supporting condition was the experience of connectedness when met with acknowledgement, flexibility and feedback from a qualified therapist in the face-to-face consultations. A key finding was that participants were motivated to persist with ICBT when their overall need for

    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. 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. 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.

    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.

    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.

    This paper constructs a model of the consensus formation in Internet based on the directed graph after analyzing the classical models of the social consensus formation, sets up the rules for the evolvement of opinions of agents and induces the evolving algorithm of consensus in Internet. The paper presents some key parameters such as the influence area of the mainstream media, the average influence of the mainstream media, the average self-persisting ability of agents and etc. Simulation results on a small-world networks show that the less the average self-persisting capability of the agents is, the easier the guidance of the media will be. The stronger the average influence of the main stream media is, the easier the mainstream media guides the consensus. These results reflect the formation law of the network consensus and are consistent approximately with the real circumstance.

    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 practice of interventional cardiology differs between countries and regions. In this study we report the results of the first nation-wide long-term comparison of interventional cardiology in two countries using a common web-based registry. The Swedish Coronary Angiography and Angioplasty Registry (SCAAR) was used to prospectively and continuously collect background-, quality-, and outcome parameters for all coronary angiographies (CA) and percutaneous coronary interventions (PCI) performed in Iceland and Sweden during one year. The rate of CA per million inhabitants was higher in Iceland than in Sweden. A higher proportion of patients had CA for stable angina in Iceland than in Sweden, while the opposite was true for ST elevation myocardial infarction. Left main stem stenosis was more commonly found in Iceland than in Sweden. The PCI rate was similar in the two countries as was the general success rate of PCI, achievement of complete revascularisation and the overall stent use. Drug eluting stents were more commonly used in Iceland (23% vs. 19%). The use of fractional flow reserve (0.2% vs. 10%) and the radial approach (0.6% vs. 33%) was more frequent in Sweden than in Iceland. Serious complications and death were very rare in both countries. By prospectively comparing interventional cardiology in two countries, using a common web based registry online, we have discovered important differences in technique and indications. A discovery such as this can lead to a change in clinical practice and inspire prospective multinational randomised registry trials in unselected, real world populations.

    Background 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. Methods 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. Results 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 < 0.001). Access to textbooks and printed journals, however, did not change over the 4-year study period. In addition, there were significant relationships between the usage of 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. Conclusions 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. PMID:23289500

    Previously, behavioural scientists seeking to create Internet-based behaviour change interventions have had to rely on computer scientists to actually develop and modify web interventions. The LifeGuide software was designed to enable behavioural researchers to develop and adapt Internet-based behavioural interventions themselves. This article reports a qualitative case study of users' experiences and perceptions of the LifeGuide software. The aim was to explore users' experiences and their perceptions of the benefits and limitations of this approach to intervention development. Twenty LifeGuide users took part in semi-structured interviews and one provided feedback via email. Thematic analysis identified three overarching themes: 'Recognising LifeGuide's potential', 'I'm not a programmer' and 'Knowledge sharing - the future of LifeGuide'. Users valued LifeGuide's potential to allow them to flexibly develop and modify interventions at little cost. However, users noted that their lack of programming experience meant that they needed to learn new skills for using the software, and they varied in the extent to which they felt able to develop interventions without any input from programmers. Respondents saw the potential of using the LifeGuide Community Website to share technical support and examples of intervention components to support their use of LifeGuide.

    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.

    Full Text Available Our previous studies have demonstrated that histidine supplementation significantly ameliorates inflammation and oxidative stress in obese women and high-fat diet-induced obese rats. However, the effects of dietary histidine on general population are not known. The objective of this Internet-based cross-sectional study was to evaluate the associations between dietary histidine and prevalence of overweight/obesity and abdominal obesity in northern Chinese population. A total of 2376 participants were randomly recruited and asked to finish our Internet-based dietary questionnaire for the Chinese (IDQC. Afterwards, 88 overweight/obese participants were randomly selected to explore the possible mechanism. Compared with healthy controls, dietary histidine was significantly lower in overweight (p < 0.05 and obese (p < 0.01 participants of both sexes. Dietary histidine was inversely associated with body mass index (BMI, waist circumference (WC and blood pressure in overall population and stronger associations were observed in women and overweight/obese participants. Higher dietary histidine was associated with lower prevalence of overweight/obesity and abdominal obesity, especially in women. Further studies indicated that higher dietary histidine was associated with lower fasting blood glucose (FBG, homeostasis model assessment of insulin resistance (HOMA-IR, 2-h postprandial glucose (2 h-PG, tumor necrosis factor-α (TNF-α, interleukin-1β (IL-1β, interleukin-6 (IL-6, C-reactive protein (CRP, malonaldehyde (MDA and vaspin and higher glutathione peroxidase (GSH-Px, superoxide dismutase (SOD and adiponectin of overweight/obese individuals of both sexes. In conclusion, higher dietary histidine is inversely associated with energy intake, status of insulin resistance, inflammation and oxidative stress in overweight/obese participants and lower prevalence of overweight/obesity in northern Chinese adults.

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

    Directory of Open Access Journals (Sweden)

    Alexander Rozental

    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

    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.

    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.

    Internet-based interventions open a chance to improve the sustainability of rehabilitation in general and of exercise therapy in particular. The internet can be the sole intervention component on the one hand as well as a supportive tool for a traditional "Face-to-Face" intervention on the other hand. In this article, 2 studies in the setting of health promotion are outlined. Those studies evaluated an e-Training program in different administration forms. Study 1: 90 adults with a sedentary lifestyle were randomized into 3 treatment groups: Group fitness ("Face-to-Face"), individually supervised training ("Face-to-Face") and e-Training (internet-based). The respective intervention took place across 3 months and each continued for a maintenance phase of 4 months. Muscular fitness, sports activities and health-related quality of life were assessed at 3 points in time: right before the intervention, after the first 3 months, and finally, after the maintenance -phase. Study 2: 509 adults with a high self-rated risk of recurrent back pain participated in the intervention "Rückengesundheit ERlangen", which lasted for 6 months: a combined program with its content delivered "Face-to-Face" and via e-Training. The analysis was conducted in a pre-post design without control group. Several psychosocial outcome variables were assessed (e.g., fear-avoidance beliefs/FABQ-D) and the cardio-pulmonary endurance capacity. In study 1 and in study 2, significant improvements over time in all intervention groups were measured in nearly all of the dependent variables, with the exception of the physical component summary of health-related quality of life (HRQL) (SF-36) in study 1, as well as its mental component summary (SF-36) and the endurance capacity in study 2. In study 1, the graphical comparison (confidence interval) of e-Training with the "Face-to-Face" interventions shows a similar efficacy of both of them. A gender-specific evaluation reveals that the mental component of HRQL

    The purpose of this qualitative study was to improve understanding of family caregivers' use of Web-based intervention support by integrating three theoretical models. The study applied the Anderson's model of health service utilization, Venkatesh's theory of technology acceptance, and Chatman's and Wilson's information behavior theories. This qualitative study is part of a larger study. An interpretive grounded theory approach was used to conduct in-depth interviews with Chinese caregivers of family members with dementia. The caregivers received Internet-based information support and personalized e-mail intervention. A purposive sample of fourteen caregivers was selected to participate in the interviews. Constant comparison, analytic memoing, case analysis, and concept mapping were used to conduct theoretical triangulation analysis. Three main factors influenced the use of the intervention: (a) caregiver needs, which are influenced by personal capacity, social support available, and caregiving belief; (b) information communication technology (ICT) factors, including accessibility barriers and perceived efforts to use the technology; and (c) style of using the technology, such as preference for using e-mail or the customized Website. The personal capacity of caregivers was influenced by many factors, including computer and language proficiency, health service knowledge, caregiving competence and competing roles and responsibilities. Social support available for caregivers included available computer, language or caregiving support and health service knowledge. Caregiving belief included traditional belief of giving care, and health belief of the illness. New caregivers needed a different kind of support intervention compared with experienced caregivers. Caregivers with different amounts of experience tended to have different learning styles, with new caregivers preferring interactive intervention and more experienced caregivers preferring more reflective learning

    Body integrity identity disorder (BIID)-a strong desire for amputation or paralysis-is often accompanied by feelings and cognitions of sexual arousal, although this sexual component has been largely neglected in the recent literature. To examine the presence of BIID-related sexual arousal in subjects with BIID and explore clinical and demographic variables of subjects with BIID who do and do not possess this sexual arousal. Eighty individuals with BIID responded to an internet-based survey we created. For all subjects, restoring identity was the primary motivation for preferred body modification. We collected data about respondents' demographic, clinical, and sexual characteristics. Based on responses to questions about BIID-specific sexual desires, subjects were assigned to the group with BIID-related sexual feelings (S-BIID; n = 57) or the group without such feelings (NS-BIID; n = 23). Differences in clinical, demographic, and sexual characteristics between S-BIID and NS-BIID groups. Of the respondents, 71.3% endorsed S-BIID. Subjects with S-BIID were significantly more often men, religious, and of a homosexual identity compared with the NS-BIID group. Subjects with S-BIID also significantly more often reported a change in localization and/or intensity of their BIID feelings over time. Furthermore, 66.7% of subjects with S-BIID reported S-BIID as an additional motivation for body modification. Seven of the 57 subjects with S-BIID achieved their preferred body modification through (self)-amputation, whereas none of the subjects with NS-BIID did. BIID is a heterogeneous disorder in which subjects who self-reported comorbid sexual arousal more often resorted to (self-induced) amputation. This study contains the largest BIID cohort presented in the literature and is the first to genuinely research sexuality in BIID. The first limitation is the lack of face-to-face interviews with the subjects, so no clinical diagnoses could be made. Moreover, there is an

    The aim was (1) to describe the development of a guided internet-based CBT (ICBT) program adapted to patients with heart failure (HF) and (2) to evaluate the feasibility of the ICBT program in regard to depressive symptoms, the time used by health care providers to give feedback, and participants' perceptions of the ICBT program. A multi-professional team developed the program and seven HF patients with depressive symptoms were recruited to the study. The Patient Health Questionnaire-9 (PHQ-9) and the Montgomery Åsberg Depression Rating-Self-rating scale (MADRS-S) were used to measure depression, and patients were interviewed about their perceptions of the program. Based on research in HF and CBT, a nine-week program was developed. The median depression score decreased from baseline to the end of the study (PHQ-9: 11-8.5; MADRS-S: 25.5-16.5) and none of the depression scores worsened. Feedback from health care providers required approximately 3h per patient. Facilitating perceptions (e.g. freedom of time) and demanding perceptions (e.g. part of the program demanded a lot of work) were described by the patients. The program appears feasible and time-efficient. However, the program needs to be evaluated in a larger randomized study. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    In this study, 1386 children aged between 6 and 16years, from schools throughout the UK, logged on to a web site before lunch during Farmhouse Breakfast Week 2004. They answered a number of questions concerning their food and drink consumption that day and performed cognitive tests of attention and episodic memory. Children who had had breakfast showed superior performance on tests of attention and memory, confirming a previous laboratory based study using the same cognitive tests. This study adds weight to the growing body of literature indicating that breakfast plays a positive role in maintaining cognitive function during the morning. Copyright © 2012 Elsevier Ltd.

    2011-12-01

    As the frequency of internet-based research has increased, it is important for researchers to consider how the conditions in which data are collected may influence the risks to participants. In particular, because internet-based data collection often occurs outside a clinical or research setting, there may be unintentional disclosures of a participant's involvement in a research study of which the researcher is unaware. The current analysis examined the responses of men who have sex with men participating in an internet-based HIV behavioural risk study when queried about the possible disclosure of their participation in the study. Fewer than 2% of participants indicated that their participation in the research study was disclosed, and all but one indicated no negative outcomes associated with the disclosure. As the field of online research continues to expand, it is important to consider risks that are unique to internet-based research, and to monitor these risks to ensure that the confidentiality of research subjects is maintained.

  13. The psychosexual profile of sexual assistants: an internet-based explorative study.

    Erika Limoncin

    Full Text Available Sexual assistance may have some aspects that resemble prostitution and others that might lead one to think of sexual assistants as similar to a group of subjects whose sexual object is disability (devotees. In this study, we investigate whether a rigorous selection and training process on the part of specialised organisations may reduce the risk of training subjects with an atypical sexual interest and behaviours resembling prostitution.The study population consisted of 152 subjects defining themselves as sexual assistants. Subjects were initially contacted on websites specifically dedicated to sexual assistants and prostitutes. One hundred and twenty subjects were selected, by propensity score analysis, and studied by means of a modified version of a semi-structured questionnaire previously developed to investigate a population of subjects attracted by disability.The study group was composed of 80 trained and 40 untrained sexual assistants, with mean ages of 41.5 (SD +/-12.58 and 44.5 (SD +/-11.62, respectively. A significant number of untrained subjects affirmed that their motivation in carrying out sexual assistance was of a remunerative nature, while this number was lower among the trained assistants (p = 0.001. Nearly all untrained subjects claimed to do one or more of the following activities during sexual assistance: sexual intercourse, oral sex, and masturbation. Among the trained subjects, however, only 47.5% claimed to do one or more of these activities, which means that there is a significant gap between trained and untrained assistants (p<0.0001. The existence of an atypical sexual interest was more evident between untrained rather than between trained subjects (p<0.0001.Sexual assistance represents a way through which people affected by disabilities may attain the right to explore their sexuality in a safe setting. This can be guaranteed only if sexual assistants are trained and carefully selected by specialised organisations.

    Internet-based support groups for cancer patients have been studied extensively; very few have focused on gynecologic cancer. We pilot-tested a web-based support group for gynecologic cancer patients and assessed women's perceptions of the intervention. Twenty-seven gynecologic cancer patients were randomized to an immediate intervention or a waitlist control group. Women participated in a 12-week, web-based support group focusing on sexuality-related topics. Semi-structured interviews were conducted to investigate the feasibility and efficacy of the intervention. Women reported benefits to participating in the intervention, including receiving support from group members and moderators, increased emotional well-being, improved feelings of body image and sexuality, and comfort in discussing sexuality online. Web-based support groups are both feasible and accepted by gynecologic cancer patients with psychosexual distress. The online format provided women with easy access to the support group and anonymity in discussing psychosexual concerns. Women with gynecologic cancer may benefit from participating in online support groups which provide an environment of relative anonymity to discuss psychosexual concerns.

    We developed a user-friendly Internet-based tool for patients undergoing total hip replacement (THR) due to osteoarthritis to predict their pain and function after surgery. In the first step, the key questions were identified by statistical modelling in a data set of 375 patients undergoing THR. Based on multiple regression, we identified the two most predictive WOMAC questions for pain and the three most predictive WOMAC questions for functional outcome, while controlling for comorbidity, body mass index, age, gender and specific comorbidities relevant to the outcome. In the second step, a pilot study was performed to validate the resulting tool against the full WOMAC questionnaire among 108 patients undergoing THR. The mean difference between observed (WOMAC) and model-predicted value was -1.1 points (95% confidence interval, CI -3.8, 1.5) for pain and -2.5 points (95% CI -5.3, 0.3) for function. The model-predicted value was within 20% of the observed value in 48% of cases for pain and in 57% of cases for function. The tool demonstrated moderate validity, but performed weakly for patients with extreme levels of pain and extreme functional limitations at 3 months post surgery. This may have been partly due to early complications after surgery. However, the outcome-prediction tool may be useful in helping patients to become better informed about the realistic outcome of their THR.

    2013-05-01

    This study aims to examine the feasibility and acceptability of an Internet-based chat support group for parents implementing family-based treatment (FBT). Participants (N = 13) were parents of adolescents with eating disorder who participated in 15 weekly online therapist-guided chat sessions. Sessions focused on encouraging and supporting parental efforts to help their child overcome an eating disorder. Chat programme satisfaction ratings were high (91.7%). Participants reported looking forward to chat sessions and would recommend the chat to others. The vast majority reported that the chat helped them cope with their child's eating disorder and to implement FBT. Participants reported feeling that they could talk openly and honestly in sessions and had a sense of belonging to the group. Relatively few technical problems were reported, and the chat was rated as accessible, convenient and easy to use. Findings provide preliminary support for the utility of an online parent chat as an adjunct to FBT. Copyright © 2012 John Wiley & Sons, Ltd and Eating Disorders Association.

    In the past 20 years, war and human rights violations have led to high rates of exposure to traumatic events among the Iraqi population. Due to the ongoing violence, many physicians and mental health professionals have left Iraq in recent years. The Internet offers new possibilities for the psychological treatment of posttraumatic stress disorder (PTSD) in conflict areas. A therapist-supported cognitive-behavioral treatment manual that has been evaluated in Western countries was translated into Arabic and culturally adapted. The treatment was conducted via the Internet by Arabic-speaking therapists and was evaluated in an uncontrolled pilot study with 15 participants. Main outcome measures were PTSD (Posttraumatic Diagnostic Scale (PDS)), depression, anxiety (Hopkins Symptom Check List-25 (HSCL-25)), and quality of life (EUROHIS). The intervention resulted in a highly significant decrease in symptoms of PTSD, depression, and anxiety. Quality of life was higher at posttreatment. All treatment effect sizes were in the large range, indicating a significant improvement in mental health symptoms and quality of life. Preliminary clinical evidence indicates that new technologies can be used to provide humanitarian aid in the form of e-mental health services, even in areas that remain highly unstable. © 2011 Elsevier Ltd.

    Trichotillomania (TTM) is characterized by recurrent hair-pulling that results in substantial hair loss. A previous pilot study demonstrated that the online self-help intervention 'decoupling' (DC) might be effective at reducing hair-pulling symptoms, with a stronger effect than progressive muscle relaxation (PMR). We aimed to extend these findings using a more robust randomized clinical trial design, including diagnostic interviews by phone, a 6-month follow-up and e-mail support. One hundred five adults with TTM were recruited online and randomly allocated to either DC (n = 55) or PMR (n = 50). The intervention lasted 4 weeks, with severity of TTM assessed at 3 time points (before intervention, immediately after intervention and at the 6-month follow-up) using the Massachusetts General Hospital Hair-Pulling Scale (MGH-HPS). Both intention-to-treat and completer analyses were conducted. Intention-to-treat analysis demonstrated highly significant and comparable symptom reductions (MGH-HPS) in both the DC and PMR groups (p < 0.001, partial x03B7;2 = 0.31) that persisted through 6 months of follow-up. Participants' subjective appraisals favoured DC in some areas (e.g. greater satisfaction with DC than PMR). Completer analyses demonstrated the same pattern as the intention-to-treat analyses. Despite subjective appraisals in favour of DC, symptom reduction was comparable in the two groups. While the results suggest that even short Internet-based interventions like DC and PMR potentially help individuals with TTM, a partial effect of unspecific factors, like regression towards the mean, cannot be ruled out. Therefore, longitudinal studies with non-treated controls are warranted. © 2015 S. Karger AG, Basel.

    The aim of this randomized controlled trial (RCT) was to investigate the effects of internet-based cognitive behavior therapy (ICBT) treatment for depression compared to treatment-as-usual (TAU) on improving work ability and quality of life in patients with mild-to-moderate depression. We also examined whether patients treated with ICBT returned to work more rapidly, that is, had fewer days of sick leave, than patients treated with TAU. This study is based on material from the PRIM-NET RCT that took place between 2010 and 2013. Primary care centers in Region Vastra Gotaland, Sweden, population about 1.6 million. A total of 77 patients with depression randomized to either ICBT (46 patients) or TAU (31 patients). Mean age of participants was 35.8 years, and 67.5% were women. Work ability was measured with the Work Ability Index, depressive symptoms with Montgomery Asberg Depression Rating Scale - self-rating version (MADRS-S), quality of life with EuroQoL-5D (EQ-5D), and number of sick leave days. Both groups showed an association between improved work ability and reduction of depressive symptoms and between improved work ability and better quality of life. ICBT could not be shown to improve work ability more than TAU among patients with mild-to-moderate depression. There were no differences between the groups concerning number of patients with sick leave or number of sick leave days. Our study indicates that a high level of work ability has an association with high health-related quality of life in patients with mild-to-moderate depression, whether they are treated with ICBT or TAU. ICBT has previously been found to be cost-effective and can be seen as a good alternative to TAU. In addition to the ICBT, an intervention oriented toward the work place might improve work ability and reduce the number of sick leave days among patients with depression.

    To date, no research has evaluated the efficacy of a stand-alone, smartphone-based intervention for individuals with an alcohol use disorder. The current pilot study evaluated the short-term outcomes of a smartphone-based intervention for alcohol use disorders compared with an Internet-based brief motivational intervention plus bibliotherapy. Adults (18 to 45 years old) with an alcohol use disorder received either the Location-Based Monitoring and Intervention for Alcohol Use Disorders (LBMI-A; n = 28), a smartphone-based intervention, or the online Drinker's Check-up plus bibliotherapy (DCU + bib; n = 26). These groups were compared using the Timeline Followback interview for percent days abstinent (PDA), percent heavy drinking days (PHDD), and drinks per week (DPW) from baseline to 6 weeks after the introduction of the interventions. Multilevel models revealed that the LBMI-A resulted in a significant increase in PDA over the course of the study, whereas the DCU + bib did not. Effect sizes for change from baseline for PDA suggest that the DCU + bib resulted in moderate a decrease, whereas the LBMI-A resulted in a large increase in PDA. Both interventions resulted in significant decreases in PHDD and DPW. The LBMI-A produced larger reductions in the first 3 to 4 weeks after the intervention was introduced than the DCU + bib. On weeks with greater LBMI-A usage, participants reported less DPW and PHDD. Both interventions resulted in significant decreases in alcohol use over the 6-week trial, which is promising for stand-alone technology-based intervention systems aimed at individuals with an alcohol use disorder.

    To describe the study protocol for a study of the effectiveness of an internet-based learning program on venous leg ulcer nursing care (eVLU) in home health care. The prevalence of venous leg ulcers is increasing as population age. The majority of these patients are treated in a municipal home healthcare setting. However, studies show nurses' lack of knowledge of ulcer nursing care. Quasi-experimental study with pre- and postmeasurements and non-equivalent intervention and comparison groups. During the study, nurses taking care of patients with a chronic leg ulcer in home health care in one Finnish municipality will use the eVLU. Nurses working in home health care in another Finnish municipality will not use it providing standard care. Nurses will complete three questionnaires during the study and they will also be observed three times at patients' homes. Nurses' perceived and theoretical knowledge is the primary outcome of the study. Funding for this study was received from the Finnish Foundation for Nursing Education in 2014. Data from this study will provide information about the effectiveness of an internet-based educational program. After completing the program nurses will be accustomed to using internet-based resources that can aid them in the nursing care of patients with a VLU. Nurses will also have better knowledge of VLU nursing care. This study is registered with the International Clinical Trials Registry, identifier NCT02224300. © 2015 John Wiley & Sons Ltd.

    2017-06-01

    When considering barriers to chronic pain treatment, there is a need to deliver nonpharmacological therapies in a way that is accessible to all individuals who may benefit. To conduct feasibility testing using a guided, Internet-based intervention for individuals with chronic pain, a novel, Internet-based, chronic pain intervention (ICPI) was developed, using concepts proven effective in face-to-face interventions. This study was designed to assess usability of the ICPI and feasibility of conducting larger-scale research, and to collect preliminary data on effectiveness of the intervention. Data were collected at baseline, after each of the six intervention modules, and 12 weeks after intervention completion. Forty-one participants completed baseline questionnaires, and 15 completed the 12-week postintervention questionnaires. At baseline, all participants reported satisfaction with the structure of the intervention and ease of use. Internet-based platforms such as Facebook aided in accrual of participants, making further large-scale study of the ICPI feasible. There is preliminary evidence suggesting that the ICPI improves emotional function but not physical function, with a small but significant decrease in pain intensity and pain interference. Most participants felt they benefited at least minimally as a result of using the ICPI. The ICPI was well received by participants and demonstrated positive outcomes in this preliminary study. Further research with more participants is feasible and necessary to fully assess the effect of this intervention. Copyright © 2016 American Society for Pain Management Nursing.

    Objectives Cognitive–behavioural therapy (CBT) is an effective treatment for body dysmorphic disorder (BDD). However, most sufferers do not have access to this treatment. One way to increase access to CBT is to administer treatment remotely via the Internet. This study piloted a novel therapist-supported, Internet-based CBT program for BDD (BDD-NET). Design Uncontrolled clinical trial. Participants Patients (N=23) were recruited through self-referral and assessed face to face at a clinic specialising in obsessive–compulsive and related disorders. Suitable patients were offered secure access to BDD-NET. Intervention BDD-NET is a 12-week treatment program based on current psychological models of BDD that includes psychoeducation, functional analysis, cognitive restructuring, exposure and response prevention, and relapse prevention modules. A dedicated therapist provides active guidance and feedback throughout the entire process. Main outcome measure The clinician-administered Yale-Brown Obsessive Compulsive Scale for BDD (BDD-YBOCS). Symptom severity was assessed pretreatment, post-treatment and at the 3-month follow-up. Results BDD-NET was deemed highly acceptable by patients and led to significant improvements on the BDD-YBOCS (p=<0.001) with a large within-group effect size (Cohen's d=2.01, 95% CI 1.05 to 2.97). At post-treatment, 82% of the patients were classified as responders (defined as≥30% improvement on the BDD-YBOCS). These gains were maintained at the 3-month follow-up. Secondary outcome measures of depression, global functioning and quality of life also showed significant improvements with moderate to large effect sizes. On average, therapists spent 10 min per patient per week providing support. Conclusions The results suggest that BDD-NET has the potential to greatly increase access to CBT, at least for low-risk individuals with moderately severe BDD symptoms and reasonably good insight. A randomised controlled trial of BDD-NET is warranted

    Full Text Available Abstract Background Internet based self-help for panic disorder (PD has proven to be effective. However, studies so far have focussed on treating a full-blown disorder. Panic symptoms that do not meet DSM-IV criteria are more prevalent than the full-blown disorder and patients with sub-clinical panic symptoms are at risk of developing PD. This study is a randomised controlled trial aimed to evaluate an Internet based self-help intervention for sub-clinical and mild PD compared to a waiting list control group. Methods Participants with mild or sub-clinical PD (N = 128 will be recruited in the general population. Severity of panic and anxiety symptoms are the primary outcome measures. Secondary outcomes include depressive symptoms, quality of life, loss of production and health care consumption. Assessments will take place on the Internet at baseline and three months after baseline. Discussion Results will indicate the effectiveness of Internet based self-help for sub-clinical and mild PD. Strengths of this design are the external validity and the fact that it is almost completely conducted online.

    Emotional disorders (ED) are among the most prevalent mental disorders. However, less than 50% of people suffering from ED receive the appropriate treatment. This situation has led to the development of new intervention proposals based on the transdiagnostic perspective, which tries to address the underlying processes common to ED. Most of these programs focus primarily on down-regulating negative affectivity, rather than increasing strengths and up-regulating positive affectivity. The data suggest the existence of disturbances in positive affectivity in these disorders, and so new interventions focusing on these problems are greatly needed. It is also essential to provide assistance to all the people in need. Information and Communication Technologies can be very useful. This study aims to evaluate the efficacy of a transdiagnostic Internet-based treatment for ED in a community sample. The protocol includes traditional CBT components, as well as a specific component to address positive affect. We intend to test this protocol, including this specific component or not, versus a waiting list control group. Moreover, we aim to test the differential effect of this specific component, and study the effectiveness (in terms of patients' acceptance) of using a self-applied Internet-based program. This paper presents the study protocol. The study is a randomized controlled trial. 207 participants will be randomly assigned to: a)Transdiagnostic Internet-based protocol (TIBP), b)Transdiagnostic Internet-based protocol + positive affect component (TIBP + PA), or c)a Waiting List control group (WL). Primary outcomes measures will be the BDI-II, the BAI, and the PANAS. Secondary outcomes will include diagnosis-specific measures of the principal disorder. Participants' treatment acceptance will also be measured. Participants will be assessed at pre-, post-treatment, and 3- and 12- month follow-ups. The data will be analyzed based on the Intention-to-treat principle. Per

    Emergency Department (ED) overcrowding is a national crisis with few prospective data to document its occurrence. The objective of this study was to prospectively collect data on variables involved in Emergency Department overcrowding (EMDOC) using an Internet-based data entry model. A prospective observational Internet-based study involving 18 hospitals over a 13-month period was designed. Investigators input data into the EmDOC Internet site at 10:00 p.m. on 7 random days each month. The study found that the primary reason for ED overcrowding was lack of inpatient beds. Important means were: patient-to-nurse ratio = 2.85, diversion was 7.4 h/24 h, and hospital census was 83%. From ED waiting room to an ED bed took a mean time of 209 min. The mean number of makeshift beds was 3.1. There was no single variable that was noted to define or predict overcrowding. Documentation of factors involved in ED overcrowding found that overcrowding was not just an ED problem, but a problem that occurs due to overcrowding in the entire institution.

    Young Onset Dementia (YOD), defined by first symptoms of cognitive or behavioral decline occurring before the age of 65 years, is relatively rare compared to dementia of later onset, but it is associated with diagnostic difficulty and heavy burden on affected individuals and their informal carers. Existing health and social care structures rarely meet the needs of YOD patients. Internet-based interventions are a novel format of delivering health-related education, counseling, and support to this vulnerable yet underserved group. The RHAPSODY (Research to Assess Policies and Strategies for Dementia in the Young) project is a European initiative to improve care for people with YOD by providing an internet-based information and skill-building program for family carers. The e-learning program focuses on managing problem behaviors, dealing with role change, obtaining support, and looking after oneself. It will be evaluated in a pilot study in three countries using a randomized unblinded design with a wait-list control group. Participants will be informal carers of people with dementia in Alzheimer's disease or behavioral-variant Frontotemporal degeneration with an onset before the age of 65 years. The primary outcome will be caregiving self-efficacy after 6 weeks of program use. As secondary outcomes, caregivers' stress and burden, carer health-related quality of life, caring-related knowledge, patient problem behaviors, and user satisfaction will be assessed. Program utilization will be monitored and a health-economic evaluation will also be performed. The RHAPSODY project will add to the evidence on the potential and limitations of a conveniently accessible, user-friendly, and comprehensive internet-based intervention as an alternative for traditional forms of counseling and support in healthcare, aiming to optimize care and support for people with YOD and their informal caregivers.

    Marital bereavement and separation or divorce are among the most stressful critical life events in later life. These events require a dissolution of social and emotional ties, adjustments in daily routine and changes in identity and perspectives for the future. After a normative grief or distress reaction, most individuals cope well with the loss. However, some develop a prolonged grief reaction. Internet-based self-help interventions have proved beneficial for a broad range of disorders, including complicated grief. Based on the task model and the dual-process model of coping with bereavement, we developed a guided internet-based self-help intervention for individuals who experienced marital bereavement, separation or divorce at least 6 months prior to enrolment. The intervention consists of 10 text-based self-help sessions and one supportive email a week. The primary purpose of this study is the evaluation of the feasibility and efficacy of the intervention compared with a waiting control group. The secondary purpose is to compare the effects in bereaved and separated participants. Furthermore, we aim to analyze other predictors, moderators and mediators of the outcome, such as age, psychological distress and intensity of use of the intervention. The design is a randomized controlled trial with a waiting control condition of 12 weeks and a 24-weeks follow-up. At least 72 widowed or separated participants will be recruited via our study website and internet forums. Primary outcomes are reductions in grief symptoms, depression and psychological distress. Secondary outcome measures are related to loneliness, satisfaction with life, embitterment and the sessions. The trial will provide insights into the acceptance and efficacy of internet-based interventions among adults experiencing grief symptoms, psychological distress and adaptation problems in daily life after spousal bereavement, separation or divorce. Findings will add to existing knowledge by (1) evaluating

    Guided Internet-based cognitive-behavioral therapy (ICBT) has been found to be effective for social anxiety disorder (SAD) by several independent research groups. However, since the extent of clinically significant change demonstrated leaves room for improvement, new treatments should be developed and investigated. A novel treatment, which has generally been found to be effective, is cognitive bias modification (CBM). This study aims to evaluate the combination of CBM and ICBT. It is intended that two groups will be compared; one group randomized to receiving ICBT and CBM towards threat cues and one group receiving ICBT and control training. We hypothesize that the group receiving ICBT plus CBM will show superior treatment outcomes. Participants with SAD (N = 128), will be recruited from the general population. A composite score combining the scores obtained from three social anxiety questionnaires will serve as the primary outcome measure. Secondary measures include self-reported depression and quality of life. All treatments and assessments will be conducted via the Internet and measurement points will be baseline, Week 2, post-treatment, and 4 months post-treatment. There is no direct evidence of the effects of combining CBM and ICBT in SAD. Adding attention-training sessions to ICBT protocols could increase the proportion of participants who improve and recover through Internet-based self-help. ClinicalTrials.gov: NCT01570400.

    Full Text Available The Internet offers a new chance for health professionals to reach population groups not usually reached through traditional information channels, for example, migrants. Criticism has, however, been raised that most health information on the Internet is not easy to read and lacks cultural sensitivity. We developed an Internet-based bilingual health assistant especially for Turkish migrants in Germany, tested its acceptance, and evaluated its usability in a participatory research design with families with and without Turkish migrant background. The interactive health assistant covered the following: nutrition, physical activity, overweight, diabetes, as well as pregnancy and pregnancy support. The idea of an Internet-based health assistant was generally accepted by all participants of the evaluation study, as long as it would be incorporated in existing appliances, such as smartphones. The bilingual nature of the assistant was welcomed especially by first generation migrants, but migrant participants also indicated that not all health information needed to be made available in a culture-specific way. The participants were least satisfied with the nutrition component, which they felt should include recipes and ingredients from the culture of origin, as well as specific aspects of food preparation.

    Web-based multicenter study. The aim of the study was to assess and compare the management strategy for traumatic thoracolumbar fractures between German and Dutch spine surgeons. To date, there is no evidence-based treatment algorithm for thoracolumbar spine fractures, thereby an international controversy concerning optimal treatment exists. In this web-based multicenter study (www.spine.hostei.com), computed tomography scans of traumatic thoracolumbar fractures (T12-L2) were evaluated by German and Dutch spine surgeons. Supplementary case-specific information such as age, sex, height, weight, neurological status, and injury mechanism were provided.By using a questionnaire, fractures were classified according to the AO-Magerl Classification, followed by 6 questions concerning the treatment algorithm. Data were analyzed using SPSS (Version 21, 76, Chicago, IL). The interobserver agreement was determined by using Cohen κ. Statistical significance was defined as P spine surgeons was found. Overall German spine surgeons had a lower threshold concerning the indication for surgical treatment (Ger 87% vs. NL 30%; P < 0.05). There was a consensus about operative stabilization of AO Type B and C injuries and injuries with neurologic deficit, whereas a discrepancy in the therapeutic algorithm for AO Type A fractures was observed. This difference was most pronounced regarding the indication for posterior (Ger 96.6%; NL 41.2%; P < 0.05) and circumferential stabilization (Ger 53.4%; NL 0%; P < 0.05) for burst fractures. There is a consensus to stabilize AO Type B and C fractures, whereas country-specific differences in the treatment of Type A fractures, especially in case of burst fractures, occur. Prospective, controlled multicenter outcome studies may provide more evidence in optimal treatment for thoracolumbar fractures. 2.

    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.

    Mental ill-health has become a large health problem and it is important for caregivers to provide effective treatment alternatives. REGASSA is a randomized controlled study performed in primary care to study the effects of 12 weeks of Internet-based cognitive behaviour therapy (ICBT) and physical exercise (PE) compared with treatment as usual (TAU) in patients with mild-to-moderate mental ill-health. The present study aimed to examine the results of these treatment alternatives on psychological functioning, stress, and sleep disturbances. The study comprised 879 patients with mental ill-health taking part in the REGASSA study. Data were collected by Interactive Voice Response (IVR), a computerized, automated telephone technique. The treatments were compared at baseline, twice during treatment, at the end of treatment and at three follow-ups after treatment. Measures used were the Outcome Questionnaire-45, the short versions of the Perceived Stress Scale, and the Karolinska Sleep Questionnaire. Linear mixed models showed that the patients in ICBT and PE had better results than in TAU on psychological functioning and sleep disturbances, p mental ill-health in improving psychological functioning, stress, and sleep disturbances and could be useful alternatives in primary care. Internet-based cognitive behaviour therapy and physical exercise proved to be effective treatment alternatives for mental ill-health patients in primary care. Automated techniques (Interactive Voice Response) could be useful for following treatment course in large groups of patients in the health care. It is important to use measures that capture different aspects of patients' health problems. The recruitment of participants was based on patients' interest and inclusion criteria which may have affect the generalizability. © 2016 The British Psychological Society.

    Bipolar disorder is a chronic condition with recurring episodes that often lead to suffering, decreased functioning, and sick leave. Pharmacotherapy in the form of mood stabilizers is widely available, but does not eliminate the risk of a new depressive or (hypo)manic episode. One way to reduce the risk of future episodes is to combine pharmacological treatment with individual or group psychological interventions. However, access to such interventions is often limited due to a shortage of trained therapists. In unipolar depression there is now robust evidence of the effectiveness of Internet-based psychological interventions, usually comprising psychoeducation and cognitive behavioral therapy (CBT). Internet-based interventions for persons suffering from bipolar disorder could increase access to psychological treatment. The aim of this study was to investigate the feasibility of an Internet-based intervention, as well as its effect on residual depressive symptoms in persons diagnosed with bipolar disorder type II (BP-II). The most important outcomes were depressive symptoms, treatment adherence, and whether the patient perceived the intervention as helpful. A total of 7 patients diagnosed with bipolar disorder type II at a Swedish psychiatric outpatient clinic were offered the opportunity to participate. Of the 7 patients, 3 (43%) dropped out before treatment began, and 4 (57%) were treated by means of an online, Internet-based intervention based on CBT (iCBT). The intervention was primarily aimed at psychoeducation, treatment of residual depressive symptoms, emotion regulation, and improved sleep. All patients had ongoing pharmacological treatment at recruitment and established contact with a psychiatrist. The duration of BP-II among the treated patients was between 6 and 31 years. A single-subject design was used and the results of the 4 participating patients were presented individually. Initiating treatment was perceived as too demanding under current life

    The aim of this cross-sectional study among Swedish hunters was to examine the association between shooting history and presence of high-frequency hearing impairment (HFHI). All hunters registered with an e-mail address in the membership roster of the Swedish Hunters' Association were invited via e-mail to a secure website with a questionnaire and an Internet-based audiometry test. Associations, expressed as prevalence ratio (PR), were multivariately modelled using Poisson regression. The questionnaire was answered by 1771 hunters (age 11-91 years), and 202 of them also completed the audiometry test. Subjective severe hearing loss was reported by 195/1771 (11%), while 23/202 (11%) exhibited HFHI upon testing with Internet-based audiometry. As many as 328/1771 (19%) had never used hearing protection during hunting. In the preceding 5 years, 785/1771 (45%), had fired >6 unprotected gunshots with hunting rifle calibers. The adjusted PR of HFHI when reporting 1-6 such shots, relative to 0, was 1.5 [95% confidence interval (CI) 1.1-2.1; P = 0.02]. We could not verify any excessive HFHI prevalence among 89 hunters reporting unprotected exposure to such gunshot noise >6 times. Nor did the total number of reported rifle shots seem to matter. These findings support the notion of a wide variation in individual susceptibility to impulse noise; that significant sound energy, corresponding to unprotected noise from hunting rifle calibers, seems to be required; that susceptible individuals may sustain irreversible damage to the inner ear from just one or a few shots; and that use of hearing protection should be encouraged from the first shot with such weapons.

IPv6 is used over low power WPAN (wireless personal area network which is run by 6LoWPAN technology on the LoWPAN devices. In order to establish seamless connection of two heterogeneous networks, that is, WSN and IPv6 network, this paper proposes an improved energy conservation and interconnection scheme (ECIS based on the analysis of the current schemes. Detailed design of each functional component in the new scheme is proposed, and an expansion of the SSCS module in NS2 802.15.4 simulator is examined. Comprehensive experiments on the simulation platform show that the newly proposed scheme is advantageous over existing results.

  2. Internet-based instruction in college teaching

    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

    Background The use of the Internet has the potential to increase access to evidence-based mental health services for a far-reaching population at a low cost. However, low take-up rates in routine care indicate that barriers for implementing Internet-based interventions have not yet been fully identified. Objective The aim of this study was to evaluate the preference for Internet-based psychological interventions as compared to treatment delivered face to face among individuals without past or current use of mental health treatment delivered online. A further aim was to investigate predictors of treatment preference and to complement the quantitative analyses with qualitative data about the perceived advantages and disadvantages of Internet-based interventions. Methods Two convenience samples were used. Sample 1 was recruited in an occupational setting (n=231) and Sample 2 consisted of individuals previously treated for cancer (n=208). Data were collected using a paper-and-pencil survey and analyzed using mixed methods. Results The preference for Internet-based psychological interventions was low in both Sample 1 (6.5%) and Sample 2 (2.6%). Most participants preferred psychological interventions delivered face to face. Use of the Internet to search for and read health-related information was a significant predictor of treatment preference in both Sample 1 (odds ratio [OR] 2.82, 95% CI 1.18-6.75) and Sample 2 (OR 3.52, 95% CI 1.33-9.29). Being born outside of Sweden was a significant predictor of preference for Internet-based interventions, but only in Sample 2 (OR 6.24, 95% CI 1.29-30.16). Similar advantages and disadvantages were mentioned in both samples. Perceived advantages of Internet-based interventions included flexibility regarding time and location, low effort, accessibility, anonymity, credibility, user empowerment, and improved communication between therapist and client. Perceived disadvantages included anonymity, low credibility, impoverished

    Internet-based self-help psychotherapy (IBT) could be an important alternative or supplement to ordinary face-to-face therapy. The findings of randomised controlled trials indicate that the effects of various IBT programmes for anxiety disorders seem better than no intervention and in some instances are equivalent to usual therapy. In Denmark, IBT is part of future treatment plans in mental health care services, but the verification level of the current clinical scientific knowledge is insufficient. The objective of this trial is feasibility assessment of benefits and harms of the Internet-based cognitive behavioural therapy (ICBT) programme FearFighter™ versus no intervention for anxiety disorders in adults. We will conduct an investigator-initiated, feasibility randomised controlled trial. Sixty-four participants are expected to be recruited via an advertisement posted on the homepage of the Student Counselling Service in Denmark. The inclusion criterion for participation in the trial will be the presence of anxiety disorder as assessed with the Mini International Neuropsychiatric Interview. The exclusion criteria will be suicidal risk, an ongoing episode of bipolar disorder or psychosis, concurrent psychological treatment for the anxiety disorder, considered unable to attend the intervention as planned (due to vacation, work/study placement, sickness, or similar occurrences), or lack of informed consent. The intervention group will be offered nine sessions with the ICBT programme FearFighter™ and a weekly telephone contact to support compliance. The control group will receive no intervention. We define the feasibility outcomes as follows: the fraction of randomised participants out of the eligible people (the lower 95 % confidence interval (CI) ≥ 50 %); and the fraction of compliant participants (those receiving at least six out of nine sessions) in the intervention group (the lower 95 % CI ≥ 60 %). The exploratory clinical outcomes are the

    The diagnosis and management of urinary tract infections (UTI) vary widely across countries and practices. The objective of this study was to gain insight into general practitioners' (GP) perceptions on the current management of UTIs and asymptomatic bacteriuria in Spain. Cross-sectional, internet-based questionnaire study answered from July to September 2013. GPs affiliated with the largest Spanish scientific society in primary care (Sociedad Española de Medicina Familiar y Comunitaria) were invited to participate in the study. They were asked about the tests ordered in both uncomplicated and complicated UTIs and about the management in three clinical scenarios, depicting a 50-year woman with: 1. An uncomplicated UTI, 2. A complicated UTI, and 3. An asymptomatic bacteriuria. The questionnaire was completed by 1,239 GPs (6.7%). Urine cultures were reportedly requested by 26.3% of the GPs in uncomplicated UTIs and by 71.8% of the cases corresponding to the complicated UTIs whereas it was declared that dipsticks were the preferred tests in only uncomplicated UTIs (38.2%). A total of 22% and 13.2% of the GPs stated that they would withhold antibiotic therapy in patients with low-count and high-count asymptomatic bacteriuria, respectively. GPs have important misconceptions as to the indications for ordering urine cultures and in interpreting the definitions of common UTIs and treating UTIs and asymptomatic bacteriuria. The unnecessary use of antibiotics in patients with asymptomatic bacteriuria is considerable in Spain.

    The aim of this study was to investigate the risk factors for absenteeism due to mental health problems with regard to company characteristics and systems for return to work in Japan. This was an Internet-based unmatched case-control study. Two hundred and fifty-eight workers who experienced over 28 days of sick leave due to mental health problems (cases) and 258 workers who have not taken sick leave (controls) were recruited. Company characteristics and the awareness and presence of systems for return to work were analysed as indicators of absenteeism. A total of 501 workers were included in the analysis. Females were less likely to experience absenteeism when adjustments were made for both the awareness and presence of systems [odds ratio (OR) = 0.51 and 0.41, respectively]. Large companies showed an increased risk of having absentee workers than small companies. The awareness of a gradual resumption system and the presence of a sick pay system were related to absenteeism (OR = 2.75 and 2.40, respectively). The awareness and presence of systems for return to work are related to the long-term absenteeism. The predictors of sex and company size are also related to the experience of the long-term absenteeism. To understand the effect of systems for return to work on absenteeism due to mental problems, further studies are needed.

    Adolescent depression is both common and burdensome, and while evidence-based strategies have been developed to prevent adolescent depression, participation in such interventions remains extremely low, with less than 3% of at-risk individuals participating. To promote participation in evidence-based preventive strategies, a rigorous marketing strategy is needed to translate research into practice. To develop and pilot a rigorous marketing strategy for engaging at-risk individuals with an Internet-based depression prevention intervention in primary care targeting key attitudes and beliefs. A marketing design group was constituted to develop a marketing strategy based on the principles of targeting, positioning/competitor analysis, decision analysis, and promotion/distribution and incorporating contemporary models of behavior change. We evaluated the formative quality of the intervention and observed the fielding experience for prevention using a pilot study (observational) design. The marketing plan focused on "resiliency building" rather than "depression intervention" and was relayed by office staff and the Internet site. Twelve practices successfully implemented the intervention and recruited a diverse sample of adolescents with > 30% of all those with positive screens and > 80% of those eligible after phone assessment enrolling in the study with a cost of $58 per enrollee. Adolescent motivation for depression prevention (1-10 scale) increased from a baseline mean value of 7.45 (SD = 2.05) to 8.07 poststudy (SD = 1.33) (P = .048). Marketing strategies for preventive interventions for mental disorders can be developed and successfully introduced and marketed in primary care.

    National guidelines emphasize healthy eating to promote wellbeing and prevention of non-communicable diseases. The perceived healthiness of food is determined by many factors affecting food intake. A positive perception of healthy eating has been shown to be associated with greater diet quality. Internet-based methodologies allow contact with large populations. Our present study aims to design and evaluate a short nutritional perception questionnaire, to be used as a screening tool for assessing nutritional status, and to predict an optimal level of personalisation in nutritional advice delivered via the Internet. Data from all participants who were screened and then enrolled into the Food4Me proof-of-principle study (n = 2369) were used to determine the optimal items for inclusion in a novel screening tool, the Nutritional Perception Screening Questionnaire-9 (NPSQ9). Exploratory and confirmatory factor analyses were performed on anthropometric and biochemical data and on dietary indices acquired from participants who had completed the Food4Me dietary intervention (n = 1153). Baseline and intervention data were analysed using linear regression and linear mixed regression, respectively. A final model with 9 NPSQ items was validated against the dietary intervention data. NPSQ9 scores were inversely associated with BMI (β = -0.181, p nutritional status and to tailor nutritional advice. NCT01530139 .

    The current study sought to conduct a preliminary investigation of the effectiveness and feasibility of a novel, self-guided online self-compassion training for reducing psychological distress and increasing self-compassion and happiness among psychology trainees. A 6-week online self-compassion cultivation program was developed and delivered to Australian psychology trainees (n = 37), and a pre-experimental repeated-measures design was used to collect change data on self-compassion, happiness, perceived stress, emotion regulation difficulties as well as symptoms of depression, anxiety, and stress. Participants reported significant increases in self-compassion and happiness and significant decreases in depression, stress, and emotion regulation difficulties between pretest and posttest, with the majority of changes maintained at 3-month follow up.  This study provides preliminary evidence supporting the effectiveness and acceptability of online self-compassion training as a positive, integrated, and meaningful way of reducing distress and promoting self-compassion and happiness among trainee psychologists. © 2016 Wiley Periodicals, Inc.

    High postpartum weight retention is a strong independent risk factor for lifetime obesity, cardiovascular disease, and type 2 diabetes in women. Interventions to promote postpartum weight loss have met with some success but have been limited by high attrition. Internet-based treatment has the potential to overcome this barrier and reduce postpartum weight retention, but no study has evaluated the effects of an internet-based program to prevent high postpartum weight retention in women. Fit Moms/Mamás Activas targets recruitment of 12 Women, Infants and Children (WIC) Supplemental Nutrition Program clinics with a total of 408 adult (>18 years), postpartum (internet-based weight loss intervention. The intervention includes: monthly face-to-face group sessions; access to a website with weekly lessons, a web diary, instructional videos, and computer-tailored feedback; four weekly text messages; and brief reinforcement from WIC counselors. Participants are assessed at baseline, six months, and 12 months. The primary outcome is weight loss over six and 12 months; secondary outcomes include diet and physical activity behaviors, and psychosocial measures. Fit Moms/Mamás Activas is the first study to empirically examine the effects of an internet-based treatment program, coupled with monthly group contact at the WIC program, designed to prevent sustained postpartum weight retention in low-income women at high risk for weight gain, obesity, and related comorbidities. This trial was registered with Clinicaltrials.gov (identifier: NCT01408147 ) on 29 July 2011.

    Full Text Available Anatabine is a Solanaceae plant family alkaloid marketed in the United States as a dietary supplement. It has demonstrated anti-inflammatory effects in vivo and in vitro, and may be useful for musculoskeletal aches and pains. The purpose of this internet-based survey study was to provide more information about anatabine users who report benefits for joint pain or stiffness. Of the 282 survey respondents, 232 (82% reported a benefit from anatabine supplementation for one or more joint pain conditions, most commonly the knee, wrists/hands/fingers, shoulder, and back, most often due to osteoarthritis or injury to the joint. Mean scores of joint pain and stiffness were significantly ( P < 0.0001 reduced after starting anatabine supplementation, and for most respondents joint pain was virtually eliminated. Around 90% of all individuals rated the effect of anatabine supplementation as good or excellent for joint pain, stiffness, functionality, and overall effects. These results provide evidence that anatabine supplementation can lead to substantial improvement of musculoskeletal aches, pains, and stiffness, and can provide benefits in some individuals for various medical conditions in multiple joint locations.

    The aim of this study was to determine the current usage, relevance, and preferences for electronic health information (EHI) in the participant surgeons' clinical, research, and teaching activities. The Internet-Based Health Information Survey (IBHIS) was conducted from August to December 2003. Thirty-seven doctors (primarily practicing in East Africa) participated, all of whom had been using the Ptolemy resources for at least 6 months. Survey questions concerned time spent reading medical literature, preferred information sources, preferred type of publication, relevance, preference for western versus local medical literature, and academic productivity. Among the 75 eligible participants, 37 (48%) responded. From these responses it was found that African surgeons with access to EHI read more than articles than they did before they had such access, and they find that the information obtained is highly relevant to their clinical, teaching, and research activities. They prefer electronic journals to textbooks and are more inclined to change their practice based on information found in western journals than local journals. Ptolemy resources helped the respondents who reported academic work write a total of 33 papers for presentation or publication. Overall, access to EHI enables doctors in Africa to read more, is relevant, and contributes directly to academic productivity; thus Western medical literature is useful in the developing world, and EHI delivery should continue to expand.

    Full Text Available This is a report of the role of Distance education (DE in enhancing education and training in developing countries. As countries compete in an ever more challenging international marketplace, they recognize the need to continually train and upgrade their citizenry. As national leaders struggle to cope with increasing populations and decreasing budgets, DE can be an additional and often essential tool in accomplishing this goal.This paper is a case study of the efforts of one college in Vietnam, Fisheries College Number 4, to develop a plan to introduce a small distance education offering to its regular courses. Its purpose was to better serve farmers in remote regions. The first author, Ramona Materi, through her company, Ingenia Consulting, carried out the work on behalf of the International Development Research Centre (IDRC, a public corporation created by the Parliament of Canada to help researchers and communities in the developing world to find solutions to their social, economic, and environmental problems. Materi’s assignment was to work with College officials to develop the DE plan and funding proposal.The paper begins with a brief description of the role of information and communications technology (ICT in education and development, particularly in South East Asia. It then provides an overview of Vietnam and its current activities in DE. The next section offers a detailed examination of the challenges the College faced in developing a plan for DE on the Internet. The paper concludes with Materi’s personal observations and commentary on lessons learned.

    The advent of electronic learning, the so-called e-learning, offers new possibilities for instruction in addition to the traditional face-to-face teaching in the education of medical students. To evaluate the additional educational value of a voluntary e-learning module in a nuclear medicine course for third-year medical students. Twenty exemplary nuclear medicine patient cases from our department were developed for e-learning purposes and presented on the internet using the web-based training program ‘CaseTrain’. Subsequently, three selected test cases were handled and evaluated by an unselected population of third-year medical students. One hundred and twenty-eight students studied the three patient cases and filled out the evaluation questionnaire completely. The most important result is that both the interest in and the subjective feeling of the knowledge level regarding the specialized field of nuclear medicine had increased significantly after working through the three e-learning cases. Ninety-seven percent of the evaluating students considered the use of computer-based learning useful. The subjective grading of the content of the cases and the handling of the software were graded with high marks by the participants, 1.9 and 2.0, respectively, on a linear scale with 1 being the best and 6 being the worst. The addition of e-learning to face-to-face teaching as a form of ‘blended learning’ is highly appreciated by medical students, and will provide an effective medium for bringing better understanding of nuclear medicine to future colleagues.

    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.

    Amblyopia is a common childhood condition, which affects 2%-3% of the population. The efficacy of conventional treatment in amblyopia seems not to be high and recently perceptual learning has been used for treating amblyopia. The aim of this study was to address the efficacy of Internet-based perceptual learning in treating amblyopia. A total of 530 eyes of 341 patients with amblyopia presenting to the outpatient department of West China Hospital of Sichuan University between February 2011 and December 2011 were reviewed. A retrospective cohort study was conducted to compare the efficacy of Internet-based perceptual learning and conventional treatment in amblyopia. The efficacy was evaluated by the change in visual acuity between pretreatment and posttreatment. The change in visual acuity between pretreatment and posttreatment by Internet-based perceptual learning was larger than that by conventional treatment in ametropic and strabismic amblyopia (pInternet-based perceptual learning was larger for patients with amblyopia not younger than 7 years (pInternet-based perceptual learning was 3.06 ± 1.42 months, while conventional treatment required 3.52 ± 1.67 months to reach the same improvement (pInternet-based perceptual learning can be considered as an alternative to conventional treatment. It is especially suitable for ametropic and strabismic patients with amblyopia who are older than 7 years and can shorten the cure time of amblyopia.

    Problem drinking is an important global health concern, causing premature mortality and morbidity. Only few problem drinkers seek professional care, unfortunately, because of multiple barriers such as insufficient change motivation, fear of stigmatization or limited access to care. The aim of this study will be to examine the effectiveness of a novel Internet intervention termed Vorvida, which was developed based on established cognitive-behavioral therapy techniques with the aim of reducing problematic alcohol consumption. A two-arm randomized control trial (RCT) will be conducted to determine whether using Vorvida results in greater reductions in self-reported problem drinking, compared with a care-as-usual/waitlist (CAU/WL) control group. There will be a baseline assessment (t0) and follow-up assessments after three (t1) and six months (t2). Inclusion criteria will be: minimum age of 18, an average consumption of alcohol >24/12 g (men/women) per day and an AUDIT-C score ≥ 3, as well as informed consent. Participants will be randomly assigned to the intervention or control condition at a ratio of 1:1. Recruitment, informed consent, randomization and assessment will be Internet-based. Primary outcome will be change in self-reported alcohol consumption between t0 and t1. Secondary outcomes will be self-reported drinking behavior, expectancies of effects of alcohol use, abstinence and relapse tendencies, self-efficacy and motivation to change. This study is expected to establish the extent to which a novel Internet intervention could contribute to reducing problem drinking among adults with mild to severe alcohol use disorders who may or may not seek or access a traditional treatments. Potentially, this program could be an effective and efficient tool to help reduce problem drinking on a population level because a great number of users can be reached simultaneously without adding burden to treating clinicians.

    The automatic tendency to attend to and focus on substance-related cues in the environment (attentional bias), has been found to contribute to the persistence of addiction. Attentional bias modification (ABM) interventions might, therefore, contribute to treatment outcome and the reduction of relapse rates. Based on some promising research findings, we designed a study to test the clinical relevance of ABM as an add-on component of regular intervention for alcohol and cannabis patients. The current protocol describes a study which will investigate the effectiveness and cost-effectiveness of a newly developed home-delivered, multi-session, internet-based ABM (iABM) intervention as an add-on to treatment as usual (TAU). TAU consists of cognitive behavioural therapy-based treatment according to the Dutch guidelines for the treatment of addiction. Participants (N = 213) will be outpatients from specialized addiction care institutions diagnosed with alcohol or cannabis dependency who will be randomly assigned to one of three conditions: TAU + iABM; TAU + placebo condition; TAU-only. Primary outcome measures are substance use, craving, and rates of relapse. Changes in attentional bias will be measured to investigate whether changes in primary outcome measures can be attributed to the modification of attentional bias. Indices of cost-effectiveness and secondary physical and psychological complaints (depression, anxiety, and stress) are assessed as secondary outcome measures. This randomized control trial will be the first to investigate whether a home-delivered, multi-session iABM intervention is (cost-) effective in reducing relapse rates in alcohol and cannabis dependency as an add-on to TAU, compared with an active and a waiting list control group. If proven effective, this ABM intervention could be easily implemented as a home-delivered component of current TAU. Netherlands Trial Register, NTR5497 , registered on 18th September 2015.

    Innovative strategies are required to improve access to evidence-based tinnitus interventions. A guided Internet-based cognitive behavioural therapy (iCBT) intervention for tinnitus was therefore developed for a U.K. Initial clinical trials indicated efficacy of iCBT at reducing tinnitus severity and associated comorbidities such as insomnia and depression. The aim of this phase III randomised controlled trial is to compare this new iCBT intervention with an established intervention, namely face-to-face clinical care for tinnitus. This will be a multi-centre study undertaken across three hospitals in the East of England. The design is a randomised, two-arm, parallel-group, non-inferiority trial with a 2-month follow-up. The experimental group will receive the guided iCBT intervention, whereas the active control group will receive the usual face-to-face clinical care. An independent researcher will randomly assign participants, using a computer-generated randomisation schedule, after stratification for tinnitus severity. There will be 46 participants in each group. The primary assessment measure will be the Tinnitus Functional Index. Data analysis will establish whether non-inferiority is achieved using a pre-defined non-inferiority margin. This protocol outlines phase III of a clinical trial comparing a new iCBT with established face-to-face care for tinnitus. If guided iCBT for tinnitus proves to be as effective as the usual tinnitus care, it may be a viable additional management route for individuals with tinnitus. This could increase access to evidence-based effective tinnitus care and reduce the pressures on existing health care systems. ClinicalTrials.gov identifier: NCT02665975 .

    Diet contributes to the increasing incidence of chronic diseases. Thus, fast, accurate, and convenient dietary assessment tools are in demand. We designed an internet-based diet and lifestyle questionnaire for Chinese (IDQC). The objective of this study was to validate its applicability and assess the dietary habits of Chinese college students.Six hundred forty-four college students from northern China were recruited and asked to complete the IDQC for the last 4 months (135 food items) and 3-day diet records (3DDRs). Food and nutrient intakes recorded in the IDQC were validated against those in the 3DDRs using the Wilcoxon matched-pairs t test, correlation analysis, and cross-classification. The Student t and χ tests were used in the dietary assessment.There were significantly positive correlations in the dietary intakes of 9 food groups and 23 nutrients between the IDQC and 3DDRs. All participants consumed low levels of fruits, vegetables, legumes, dairy, and certain micronutrients (ie, vitamin A, vitamin B1, vitamin B2, folic acid, vitamin C, calcium, selenium, and iodine), and high levels of iron and manganese. Male students consumed higher intakes of the food groups and nutrients than female students.The IDQC represents an accurate and convenient dietary assessment tool that can be used in large populations. Inadequate and excessive nutrition co-existed in college students, and more fruits, vegetables, legumes, dairy, and various vitamins and minerals were needed in this population's daily diet. The IDQC is free of access at www.yyjy365.org/diet.

    Major depression and depressive symptoms are common in patients with a recent myocardial infarction (MI), and depression is associated with adverse cardiovascular outcomes. Anxiety post-MI is less studied, but occurs commonly in patients with heart disease, and is also considered a risk factor for recurrence of cardiac events. Cognitive behavior therapy (CBT) is an established therapy for depression and anxiety disorders. To the best of our knowledge, there have not been any studies to determine if internet-based CBT (iCBT) can reduce the symptoms of depression and anxiety in patients with a recent MI. The main aim of the U-CARE Heart trial is to evaluate an iCBT intervention for patients with a recent MI. This is a randomized, controlled, prospective study with a multicenter design. A total of 500 participants will be randomized at a 1:1 ratio, around two months after an acute MI, to either iCBT or to a control group. Both groups will receive an optimal standard of care according to guidelines. The intervention consists of a self-help program delivered via the internet with individual online support from a psychologist. Treatment duration is 14 weeks. The primary outcome is change in patients' self-rated anxiety and depression symptoms from baseline to end of treatment. An internal pilot study was conducted indicating sufficient levels of study acceptability and engagement in treatment. The present study is designed to evaluate an iCBT intervention targeting symptoms of depression and anxiety in a post-MI population. If effective, iCBT has several advantages, and will potentially be implemented as an easily accessible treatment option added to modern standard of care. This trial was registered with Clinicaltrials.gov (identifier: NCT01504191 ) on 19 December 2011.

    Mindfulness-based interventions have shown to reduce psychological distress in cancer patients. The accessibility of mindfulness-based interventions for cancer patients could be further improved by providing mindfulness using an individual internet-based format. The aim of this study is to test the effectiveness of a Mindfulness-Based Cognitive Therapy (MBCT) group intervention for cancer patients in comparison with individual internet-based MBCT and treatment as usual (TAU). A three-armed multicenter randomized controlled trial comparing group-based MBCT to individual internet-based MBCT and TAU in cancer patients who suffer from at least mild psychological distress (Hospital Anxiety and Depression Scale (HADS) ≥ 11). Measurements will be conducted prior to randomization (baseline), post-treatment and at 3 months and 9 months post-treatment. Participants initially allocated to TAU are subsequently randomized to either group- or individual internet-based MBCT and will receive a second baseline measurement after 3 months. Thus, the three-armed comparison will have a time span of approximately 3 months. The two-armed intervention comparison includes a 9-month follow-up and will also consist of participants randomized to the intervention after TAU. Primary outcome will be post-treatment psychological distress (HADS). Secondary outcomes are fear of cancer recurrence (Fear of Cancer Recurrence Inventory), rumination (Rumination and Reflection Questionnaire), positive mental health (Mental Health Continuum - Short Form), and cost-effectiveness (health-related quality of life (EuroQol -5D and Short Form-12) and health care usage (Trimbos and iMTA questionnaire on Costs associated with Psychiatric illness).

    The network requirements of control systems in industrial applications increase day by day. The Internet based control system and various fieldbus systems have been designed in order to meet these requirements. This paper describes an Internet based control system with wireless fieldbus communication designed for distributed processes. The system was implemented as an experimental setup in a laboratory. In industrial facilities, the process control layer and the distance connection of the distributed control devices in the lowest levels of the industrial production environment are provided with fieldbus networks. In this paper, the Internet based control system that will be able to meet the system requirements with a new-generation communication structure, which is called wired/wireless hybrid system, has been designed on field level and carried out to cover all sectors of distributed automation, from process control, to distributed input/output (I/O). The system has been accomplished by hardware structure with a programmable logic controller (PLC), a communication processor (CP) module, two industrial wireless modules and a distributed I/O module, Motor Protection Package (MPP) and software structure with WinCC flexible program used for the screen of Scada (Supervisory Control And Data Acquisition), SIMATIC MANAGER package program ("STEP7") used for the hardware and network configuration and also for downloading control program to PLC.

    The management of whiplash associated disorders is one of the most complicated challenges with high expenses for the health care system and society. There are still no general guidelines or scientific documentation to unequivocally support any single treatment for acute care following whiplash injury. The main purpose of this study is to try a new behavioural medicine intervention strategy at acute phase aimed to reduce the number of patients who have persistent problems after the whiplash injury. The goal is also to identify which of three different interventions that is most cost-effective for patients with whiplash associated disorders. In this study we are controlling for two factors. First, the effect of behavioural medicine approach is compared with standard care. Second, the manner in which the behavioural medicine treatment is administered, Internet or face-to-face, is evaluated in it's effectiveness and cost-effectiveness. The study is a randomized, prospective, experimental three-group study with analyses of cost-effectiveness up to two-years follow-up. Internet - based programme and face-to-face group treatment programme are compared to standard-treatment only. Patient follow-ups take place three, six, twelve and 24 months, that is, short-term as well as long-term effects are evaluated. Patients will be enrolled via the emergency ward during the first week after the accident. This new self-help management will concentrate to those psychosocial factors that are shown to be predictive in long-term problems in whiplash associated disorders, i.e. the importance of self-efficacy, fear of movement, and the significance of catastrophizing as a coping strategy for restoring and sustaining activities of daily life. Within the framework of this project, we will develop, broaden and evaluate current physical therapy treatment methods for acute whiplash associated disorders. The project will contribute to the creation of a cost-effective behavioural medicine

    Internet-based self-management (IBSM) support cost-effectively improves asthma control, asthma related quality of life, number of symptom-free days, and lung function in patients with mild to moderate persistent asthma. The current challenge is to implement IBSM in clinical practice. This study is a three-arm cluster randomized trial with a cluster pre-randomisation design and 12 months follow-up per practice comparing the following three IBSM implementation strategies: minimum strategy (MS): dissemination of the IBSM program; intermediate strategy (IS): MS + start-up support for professionals (i.e., support in selection of the appropriate population and training of professionals); and extended strategy (ES): IS + additional training and ongoing support for professionals. Because the implementation strategies (interventions) are primarily targeted at general practices, randomisation will occur at practice level.In this study, we aim to evaluate 14 primary care practices per strategy in the Leiden-The Hague region, involving 140 patients per arm. Patients aged 18 to 50 years, with a physician diagnosis of asthma, prescription of inhaled corticosteroids, and/or montelukast for ≥3 months in the previous year are eligible to participate. Primary outcome measures are the proportion of referred patients that participate in IBSM, and the proportion of patients that have clinically relevant improvement in the asthma-related quality of life. The secondary effect measures are clinical outcomes (asthma control, lung function, usage of airway treatment, and presence of exacerbations); self-management related outcomes (health education impact, medication adherence, and illness perceptions); and patient utilities. Process measures are the proportion of practices that participate in IBSM and adherence of professionals to implementation strategies. Cost-effective measurements are medical costs and healthcare consumption. Follow-up is six months per patient. This study

    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.

    Despite evidence of successful weight loss for bariatric surgery patients, some patients experience considerable weight regain over the long term. Given the strong association between post-surgery health behaviors and outcomes, aftercare intervention to address key behaviors appears to be a reasonable relapse-prevention strategy. As the burden of obesity rates increases in healthcare centers, an internet-based program appears to be a reasonable strategy for supporting bariatric surgery patients in the long term. The primary purpose of the current project is to develop and test the efficacy and perceived utility of APOLO-Bari. This study is a randomized control trial, which will be conducted in two hospital centers in the North of Portugal; it includes a control group receiving treatment as usual and an intervention group receiving the APOLO-Bari program for one year in addition to treatment as usual. A total of 180 male and female participants who underwent bariatric surgery (gastric sleeve or gastric bypass surgery) for 12 to 20 months will be recruited. Both groups will complete a similar set of questionnaires at baseline, every 4 months until the end of the intervention, and at 6 and 12 months follow-up. Assessment includes anthropometric variables and psychological self-report measures. The primary outcome measure will be weight regain measured at the end of treatment, and at 6 and 12 months follow-up. The secondary aims are to test the cost-effectiveness of the intervention and to investigate psychological predictors and trajectories of weight regain. APOLO-Bari was developed to address the weight regain problem in the bariatric population by offering additional guidance to bariatric patients during the postoperative period. The program includes: (a) a psychoeducational cognitive-behavioral-based self-help manual, (b) a weekly feedback messaging system that sends a feedback statement related to information reported by the participant, and (c) interactive chat

    There are multiple ways in which community pharmacies can present themselves on the Internet, e.g., as a platform for drug information or as an advertising platform for their services. To estimate the number of Swiss community pharmacies on the Internet over the period of 32 months (2000-2003), to describe their current e-commerce services, and to explore the experiences and plans these pharmacies have with regard to their Internet presence. A longitudinal study was performed to determine the number of Swiss German pharmacies on the Internet by conducting Internet searches in 2000, 2001, and 2003. In April 2002, a cross-sectional Internet-based survey was administered to explore the pharmacies' experiences and plans regarding their Web sites. As of April 2003, 373 (44%) of 852 community pharmacies from the German speaking part of Switzerland were on the Internet. One hundred eighty four listed an e-mail address and were asked to complete a questionnaire. Of the 107 pharmacies answering the survey questions (58% response rate): 46% had been on the Internet for 1 to 2 years; 33% of the Web sites are part of a pharmacy group's Web portal; 31% of the pharmacies plan to expand their Internet appearance in the future; 74% provide e-commerce services, with 81% of those pharmacies filling five or less orders per month; and 12% plan on expanding their e-commerce services in the future. The number of community pharmacies offering Internet services steadily increased over 32 months. Given the importance of the Internet as a tool for information, communication, and advertising for pharmacy products and services, it can be expected that the increase will continue. Pharmacy-group portals are important promoters of pharmacies on the Internet. For many community pharmacies, Internet portals that provide an Internet presence for the pharmacies and provide regularly-updated content (e.g., health news, tips, drug information) seem to be the most effective solutions.

    During the last decade online interventions have emerged as a promising approach for patients with mild/moderate depressive symptoms, reaching at large populations and representing cost-effective alternatives. The main objective of this double-blind, randomized controlled trial is to examine the efficacy of an internet-based self-management tool (iFightDepression) for mild to moderate depression as an add-on to treatment as usual (TAU) versus internet-based psychoeducation plus TAU. A total of 310 participants with major depression disorder (MDD) will be recruited at four different mental-health facilities in Spain. Participants will be randomly allocated to one of two study arms: iFightDepression (iFD) tool + TAU vs. internet-based psychoeducation + TAU. Both interventions last for 8 weeks and there is a 12 weeks follow up. The primary outcome measure is changes in depressive symptoms assessed with the Hamilton Depression Rating Scale. Additionally, pre-post interventions assessments will include socio-demographic data, a brief medical and clinical history and self-reported measures of depressive symptoms, quality of life, functional impairments and satisfaction with the iFD tool. iFightDepression is an easy-prescribed tool that could increase the efficacy of conventional treatment and potentially reach untreated patients, shortening waiting lists to receive psychological treatment. Confirming the efficacy of the iFD internet-based self-management tool as an add-on treatment for individuals with mild to moderate depression will be clinically-relevant.

    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

    Discussion: This study will contribute to the evidence base of internet-based pain interventions and provide valuable information about the treatment success and cost-effectiveness regarding the intervention's level of guidance (self-help only vs. guided self-help. If ACTonPain is shown to be effective, investigations in different healthcare settings should follow, to examine possible ways of implementing ACTonPain into existing healthcare systems. The implementation of ACTonPain could help to shorten waiting times, expand access to pain treatment and, potentially, also reduce treatment costs.

    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.

    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.

    This randomized controlled trial aimed at evaluating the efficacy of an internet-based cognitive behavioral stress management program (IB-CBSM) for pregnant women with preterm labor (PTL) on birth outcome and stress-related psychological and biological parameters. 93 pregnant women with PTL (gestational age 18-32) were assigned to either the IB-CBSM (n=50) or a control group (CG) based on distraction (n=43). Participants in both groups worked through six weekly modules. Birth outcome measures included gestational age, neonatal weight and length at birth and the rate of preterm birth (PTB). Questionnaires assessed psychological wellbeing and the activity of the HPA-axis was measured with the cortisol awakening reaction (CAR), both before (T1) and after the intervention (T2). Birth outcome and psychological wellbeing did not differ between IB-CBSM and CG. However, psychological wellbeing was higher after both interventions (PSS: η p 2 =0.455, STAIX1: η p 2 =0.455, STAIX2: η p 2 =0.936, PRAT: η p 2 =0.465, EPDS: η p 2 =0.856). Cortisol levels were stable and did not alter differently between groups from T1 to T2. Higher cortisol levels were associated with lower gestational age at birth, whereas no significant correlations were found between weight and length at birth. Although there were no significant differences between the two groups and birth outcome, psychological and biological parameters, both interventions (CBSM and CG) showed equivalent effects and proved to be beneficial with regard to psychosocial distress and well-being. Further research is needed to investigate CBSM and distraction interventions for pregnant women at risk for PTB together with a non-intervention control condition. Copyright © 2017 Elsevier Inc.

    Full Text Available Although the effectiveness of therapist-guided internet-based cognitive behaviour therapy (ICBT for treating depression has been well documented, knowledge of outcome predictors and risk factors associated with lower treatment response is limited, especially when the treatment has been conducted within a naturalistic clinical setting. Identification of such factors is important for clinicians when making treatment recommendations.Data from a large cohort (N = 1738 of adult outpatients having been treated with ICBT for depression at an outpatient psychiatric clinic were analysed. A multilevel modelling approach was used to identify patient and treatment variables associated with the speed of recovery during treatment using weekly measurements of the Montgomery Åsberg Depression Rating Scale Self-Rated (MADRS-S.Adhering to the treatment, perceiving it as credible and working full-time emerged as predictors of a faster pace of recovery and were also associated with a lower level of depression at the end of treatment. Higher pre-treatment depression and sleep problems were associated with a greater improvement rate, but predicted higher depression after treatment. Having a history of psychotropic medication was associated with both slower improvement and higher post-treatment depression.Perceived credibility of ICBT is a strong predictor of treatment response. Assessing patient beliefs and expectations may be a useful aid for clinicians when identifying those who are more or less likely to benefit from ICBT. Helping patients improve expectations prior to treatment may be an important goal for clinicians during the initial assessment phase.

    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.

    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

    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.

    The project 'Internet-Based Discourse' is supposed to pave the way for a more intense usage of discourse within the medium Internet. In this context a constitutive element of the method is to try out an Internet-Based Discourse in combination of real and Internet-based communication. This new method fully fulfilled the expectations put into it, which are a higher commitment of participation, the avoidance of communication pathologies and the initiation and support of group processes. As long as the distribution of access to the Internet has not reached that of the telephone, the person organising social discourses of technology assessment inevitably has to provide access to the Internet for reasons of a democratic chance of equal opportunities for social groups to participate. In the interest of a continuous discussion, unlimited access to the Internet is necessary. This goal cannot be reached sufficiently by a joint use of computer rooms in the evenings, as is already the case at night schools. Additional co-operations with Internet-cafes, libraries, communes and other pursuers of public access to the Internet could help at this point. This pilot-study did not apply multimedia elements (video, sound, animation) as to limit the expenditure of making and to avoid too great demands on the capacity of the public net access in use. However, Internet-Discourses laid out on a larger scale to justify a higher expenditure for the preparation of material. Therefore, for further Internet-Based Discourses multimedia-elements should find use only where it makes sense didactically and where it helps to clarify the facts. To bring the various discussion groups together, it makes sense to apply a moderator for the Internet-Forum. The moderator should be present at the introductory meetings to be known personally by the discourse participants. Further group meetings may be organised and moderated by a member of the group on the spot. Although, one has to make sure by

    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 information and communication technology (ICT) is a tool of development for acting or prospective teachers. In geography, however, this competence often needs directed improvement, especially for the students less information and motivation for using the full potential of this tool. In the MA program for prospective teachers of geography there is a course held by one of the authors (PTI) to introduce the students into all possibilities of ICT. The course is focused at and widely illustrated by the GEOGRAPHY nEtQUIPMENT, which is a homepage, first published in Hungarian still in 2006 (http://netszkozkeszlet.ektf.hu), to help in orientation among the rapidly growing information on the Internet. The main objective of the GEOGRAPHY nEtQUIPMENT is to convey structured information to teachers and pupils, as well as, professors and students of geography. It can be used free after registration. The homepage counts ca. three thousand registered users. The English version is available from the same entry. The set of appliances is based on Dreamweaver MX program. Development of the students' ICT-competence was measured in 2008 during the course. Before the course 38 students answered 110 questions and, after the course, the same questions were answered by 29 students. The questions were related to their attitude to ICT, technical abilities in using a PC and projections on application in a school environment. In 31 cases the answers fell into one category not allowing the chi2 test. From the 79 remained questions, there where not any which were reflected significant step-back in the ICT-competence. At the same time, significant improvement of the competence appeared in 29, 41 and 48 % of the questions at the 1, 5 and 10 % level. The course and the homepage also improved their ability to (i) memorise and reconstruct the pieces of knowledge, (ii) reconstruct the patterns in space from their 2D-images, (iii) explain the images and documents in their own words, and (iv) co

    To review the characteristics and effects Internet-based youth smoking prevention and cessation programs. Systematic review of published articles in peer-reviewed journals in the past 10 years, focused on Internet-based youth smoking prevention and cessation programs. Twelve articles were selected based on the following criteria: studies reporting the outcomes of Internet-based smoking cessation or prevention intervention programs for adolescents who are younger than 24 years. The components of youth Internet-based smoking intervention programs are analyzed based on study features (i.e., sample, design, theoretical basis, analysis, outcome measures) and program characteristics (i.e., focus, setting, frequency, duration, intensity, and different components) that make the programs effective. The most common components of effective Internet-based programs are identified as the following: the use of multimedia, tailored approaches, personalized feedback, and interactive features. The characteristics and effects of the programs vary, but most programs show positive results in youth smoking prevention and cessation in spite of the studies' limitations. The evidence from this review provides useful information of recent efforts related to Internet-based youth smoking prevention and cessation programs, which can have significant clinical implications in developing future innovative youth smoking prevention and intervention programs. © 2014 Sigma Theta Tau International.

    Lattice and Avellino's dystrophies among dystrophies and Salzmann's nodular degeneration showed specific stromal deposits making them easily diagnosable at histopathology, whereas the rest showed non-specific stromal changes mandating correlation with clinical findings. Seven regraft corneas showed stromal fibrosis making identification of primary dystrophy impossible. However, transmural vascularization and lymphocytic stromal infiltrate were prominently noted in failed grafts though their numbers were few. Conclusion: This histopathologic study characterizes classic features of macular, Avellino's, lattice corneal dystrophies and Salzmann's degeneration for their microscopic diagnosis, while the rest showed non-specific changes. Stromal edema was prominently noted in degenerations than in dystrophies. Degree of stromal vascularization and type of cellular infiltrate need attention in regrafts.

    Depression and anxiety are common and co-morbid disorders that affect a significant proportion of students. Innovative prevention strategies targeting both conditions are needed to reduce their health burden and costs. ICare Prevent is such an innovative strategy and contains a transdiagnostic individually tailored Internet-based and mobile-supported intervention. It addresses common risk factors of depression and anxiety as part of a large EU-funded multi-country project* (ICare). Little is known about the clinical and cost-effectiveness of this type of intervention compared to care as usual (CAU) for college students. We hypothesize that ICare Prevent will be more (cost-)effective than CAU in the reduction of symptoms of depression and anxiety. A three-arm, parallel, randomized controlled superiority trial will be conducted comparing a guided and an unguided version of ICare Prevent with a control group receiving CAU. The trial will be open-label but outcome assessors will be blinded. A total of 252 college students (age ≥ 16 years) with subclinical symptoms of depression defined as a score ≥ 16 on the Center for Epidemiological Studies Depression Scale (CES-D), and/or anxiety, defined as a score ≥ 5 on the Generalized Anxiety Disorder scale (GAD-7), will be included. Those meeting diagnostic criteria for a depressive or anxiety disorder will be excluded. The primary outcome is change in disorder specific symptom severity from baseline to post-intervention. Secondary endpoints include self-reported depression and anxiety symptoms as well as time to onset of a mood or anxiety disorder until 12-month follow-up. Societal costs and quality of life will be assessed to estimate the intervention's cost-effectiveness compared to CAU. Transdiagnostic individually tailored Internet-based prevention could be a (cost-)effective approach to tackle the disease burden of depression and anxiety among college students.

    Internet-based patient portals are intended to improve access and quality, and will play an increasingly important role in health care, especially for diabetes and other chronic diseases. Diabetes patients with limited health literacy have worse health outcomes, and limited health literacy may be a barrier to effectively utilizing internet-based health access services. We investigated use of an internet-based patient portal among a well characterized population of adults with diabetes. We estimated health literacy using three validated self-report items. We explored the independent association between health literacy and use of the internet-based patient portal, adjusted for age, gender, race/ethnicity, educational attainment, and income. Among 14,102 participants (28% non-Hispanic White, 14% Latino, 21% African-American, 9% Asian, 12% Filipino, and 17% multiracial or other ethnicity), 6099 (62%) reported some limitation in health literacy, and 5671 (40%) respondents completed registration for the patient portal registration. In adjusted analyses, those with limited health literacy had higher odds of never signing on to the patient portal (OR 1.7, 1.4 to 1.9) compared with those who did not report any health literacy limitation. Even among those with internet access, the relationship between health literacy and patient portal use persisted (OR 1.4, 95% CI 1.2 to 1.8). Diabetes patients reporting limited health literacy were less likely to both access and navigate an internet-based patient portal than those with adequate health literacy. Although the internet has potential to greatly expand the capacity and reach of health care systems, current use patterns suggest that, in the absence of participatory design efforts involving those with limited health literacy, those most at risk for poor diabetes health outcomes will fall further behind if health systems increasingly rely on internet-based services.

    This study aims to examine the association between the ratio of dietary branched chain amino acids (BCAA) and risk of obesity among young northern Chinese adults. A total of 948 randomly recruited participants were asked to finish our internet-based dietary questionnaire for the Chinese (IDQC). Associations between dietary BCAA ratio and prevalence of overweight/obesity and abdominal obesity were analyzed. Furthermore, 90 subjects were randomly selected to explore the possible mechanism. Dietary BCAA ratio in obese participants was significantly lower than non-obese participants. We found negative correlations between the ratio of dietary BCAA and body mass index (BMI) (r = -0.197, p obesity were 0.508 (0.265-0.972) and 0.389 (0.193-0.783), respectively (all p obesity, the multivariable-adjusted OR (95% CI) of the 3rd and 4th quartile of dietary BCAA ratio were 0.351 (0.145-0.845) and 0.376 (0.161-0.876), respectively (all p obesity, postprandial glucose and status of inflammation in young northern Chinese adults.

    The objective of this study was to clarify the relationship between sickness presenteeism and the degree of awareness of company regulations regarding financial compensation for absenteeism. An Internet-based survey of 258 full-time workers who had more than 28 days of sickness absence due to mental health problems was conducted. Workers were categorized as having either low or high sickness presenteeism, and awareness and presence or absence of systems for return to work and duration of financial compensation were compared between groups. The following factors were significantly related to high sickness presenteeism based on logistic regression analyses: working for a private company (odds ratio [OR]=2.57; 95% confidence interval [CI]=1.10-5.99); recognition of a gradual resumption system (OR=3.89, 95% CI=1.02-14.81); and awareness regarding the duration of financial compensation (OR=1.04, 95% CI=1.01-1.07). No relationship was found between mental sickness presenteeism and presence or absence of systems for return to work in our multivariate analysis; however, a relationship was apparent between sickness presenteeism and characteristics of the workers' companies. These results are expected to contribute to research involving human resources and occupational health.

    Evidence-based psychological treatments, such as cognitive behavior therapy (CBT), have been found to be effective in treating several anxiety and mood disorders. Nevertheless, issues regarding adherence are common, such as poor patient compliance on homework assignments and therapists' drifting from strictly evidence-based CBT. The development of Internet-delivered CBT (ICBT) has been intensive in the past decade and results show that guided ICBT can be as effective as face-to-face CBT but also indicate a need to integrate the two forms of CBT delivery. In this study, we developed and tested a new treatment format in which ICBT and face-to-face therapy were blended. We designed a support system accessible via the Internet (using a computer or an Apple iPad) for patients and therapists delivering CBT face-to-face. The support system included basic CBT components and a library of interventions gathered from existing ICBT manuals. The study involved 15 patients with mild to moderate anxiety or depression (or both). Eight therapists conducted the treatments. All participants were interviewed after the nine-week intervention. Further, patients provided self-reports on clinical measures pre- and post-trial, as well as at a 12-month follow-up. A reduction was found in symptom scores across all measures. The reliable change index ranged from 60% to 87% for depression and anxiety. Large effect sizes (Cohen's d) ranging from 1.62 (CI 95% 0.59-2.66) to 2.43 (CI 95% 1.12-3.74) were found. There were no missing data and no treatment dropouts. In addition, the results had been maintained at the 12-month follow-up. Qualitative interviews revealed that the users perceived the support system as beneficial. The results suggest that modern information technology can effectively blend with face-to-face treatments and be used to facilitate communication and structure in therapy, thus reducing therapist drift.

    Recent research has examined the context in which preference for specific online activities arises, leading researchers to suggest that excessive Internet users are engaged in specific activities rather than 'generalized' Internet use. The present study aimed to partially replicate and expand these findings by addressing four research questions regarding (i) participants' preferred online activities, (i) possible expected changes in online behavior in light of hypothetical scenarios, (iii) perceived quality of life when access to Internet was not possible, and (iv) how participants with self-diagnosed Internet addiction relate to intensity and frequency of Internet use. A cross-sectional design was adopted using convenience and snowball sampling to recruit participants. A total of 1057 Internet users with ages ranging from 16 to 70 years (M age  = 30 years, SD = 10.84) were recruited online via several English-speaking online forums. Most participants indicated that their preferred activities were (i) accessing general information and news, (ii) social networking, and (iii) using e-mail and/or online chatting. Participants also reported that there would be a significant decrease of their Internet use if access to their preferred activities was restricted. The study also found that 51% of the total sample perceived themselves as being addicted to the Internet, while 14.1% reported that without the Internet their life would be improved. The context in which the Internet is used appears to determine the intensity and the lengths that individuals will go to use this tool. The implications of these findings are further discussed.

    The America on the Move (AOM) Family Intervention Program has been shown to prevent excess weight gain in overweight children. Providing intervention materials via the internet would have the potential to reach more families but may increase sedentary behavior. The purpose was to evaluate whether delivering the AOM Family Intervention via the internet versus printed workbook would have a similar impact on sedentary behaviors in children. 131 children (age 8-12) were randomized to receive the AOM Family Intervention via the internet or workbook for 12 weeks. Changes in objectively measured sedentary time and moderate-to vigorous physical activity (MVPA) as well as self-reported screen time were compared between groups. There were no significant differences between groups in screen time, sedentary time, or MVPA at the end of the 12 week intervention. Families receiving the intervention via the internet were more likely to remain in the study (98% vs. 82%, P = .016). Using the internet to deliver the lifestyle intervention did not increase sedentary behavior in children. Attrition rates were lower when the program was delivered by internet versus via printed materials. These results provide support for using the internet to deliver healthy lifestyle programs for children.

    This article reports a pilot study of a new smoking cessation website ('StopAdvisor'), which has been developed on the basis of PRIME theory, evidence, web-design expertise and user-testing. The aims were to i) evaluate whether cessation, website usage and satisfaction were sufficiently high to warrant a randomised controlled trial (RCT) and ii) assess whether outcomes were affected by socio-economic status. This was an uncontrolled pilot study. Two hundred and four adult daily smokers willing to make a serious quit attempt were included. All participants received support from 'StopAdvisor', which recommends a structured quit plan and a variety of evidence-based behaviour change techniques for smoking cessation. A series of tunnelled sessions and a variety of interactive menus provide tailored support for up to a month before quitting through until one-month post-quit (http://www.lifeguideonline.org/player/play/stopadvisordemonstration). The primary outcome was self-report of at least 1month of continuous abstinence collected at 2months post-enrolment and verified by saliva cotinine or anabasine. Usage was indexed by log-ins and page views. Satisfaction was assessed by dichotomous ratings of helpfulness, personal relevance, likelihood of recommendation and future use, which were collected using an online questionnaire at 2months post-enrolment. Outcomes according to socio-economic status were assessed. At 8weeks post-enrolment, 19.6% (40/204) of participants were abstinent according to the primary outcome criteria (95% C.I.=14.1% to 25.1%). Participants viewed a mean of 133.5 pages (median=71.5) during 6.4 log-ins (median=3). A majority of respondents rated the website positively on each of the four satisfaction `ratings (range=66.7% to 75.3%). There was no evidence of an effect of socio-economic status on abstinence (OR=1.01, C.I.=0.50-2.07), usage (page-views, t(202)=0.11, p=.91; log-ins, t(202)=0.21, p=.83), or satisfaction (helpfulness, OR=1.09, C.I.=0

    Anxiety, depressive and substance use disorders account for three quarters of the disability attributed to mental disorders and frequently co-occur. While programs for the prevention and reduction of symptoms associated with (i) substance use and (ii) mental health disorders exist, research is yet to determine if a combined approach is more effective. This paper describes the study protocol of a cluster randomised controlled trial to evaluate the effectiveness of the CLIMATE Schools Combined intervention, a universal approach to preventing substance use and mental health problems among adolescents. Participants will consist of approximately 8400 students aged 13 to 14-years-old from 84 secondary schools in New South Wales, Western Australia and Queensland, Australia. The schools will be cluster randomised to one of four groups; (i) CLIMATE Schools Combined intervention; (ii) CLIMATE Schools - Substance Use; (iii) CLIMATE Schools - Mental Health, or (iv) Control (Health and Physical Education as usual). The primary outcomes of the trial will be the uptake and harmful use of alcohol and other drugs, mental health symptomatology and anxiety, depression and substance use knowledge. Secondary outcomes include substance use related harms, self-efficacy to resist peer pressure, general disability, and truancy. The link between personality and substance use will also be examined. Compared to students who receive the universal CLIMATE Schools - Substance Use, or CLIMATE Schools - Mental Health or the Control condition (who received usual Health and Physical Education), we expect students who receive the CLIMATE Schools Combined intervention to show greater delays to the initiation of substance use, reductions in substance use and mental health symptoms, and increased substance use and mental health knowledge. This trial is registered with the Australian and New Zealand Clinical Trials registry, ACTRN12613000723785.

    Full Text Available Abstract Background Gambling disorders affect about one percent of adults. Effective treatments are available but only a small proportion of affected individuals will choose to attend formal treatment. As a result, self-directed treatments have also been developed and found effective. Self-directed treatments provide individuals with information and support to initiate a recovery program without attending formal treatment. In previous research we developed an telephone-based intervention package that helps people to be motivated to tackle their gambling problem and to use basic behavioral and cognitive change strategies. The present study will investigate the efficacy of this self-directed intervention offered as a free online resource. The Internet is an excellent modality in which to offer self-directed treatment for gambling problems. The Internet is increasingly accessible to members of the public and is frequently used to access health-related information. Online gambling sites are also becoming more popular gambling platforms. Method/Design A randomized clinical trial (N=180 will be conducted in which individuals with gambling problems who are not interested in attending formal treatment are randomly assigned to have access to an online self-directed intervention or to a comparison condition. The comparison condition will be an alternative website that offers a self-assessment of gambling involvement and gambling-related problems. The participant’s use of the resources and their gambling involvement (days of gambling, dollars loss and their gambling problems will be tracked for a twelve month follow-up period. Discussion The results of this research will be important for informing policy-makers who are developing treatment systems. Trial registration ISRCTN06220098

    To examine the feasibility of an online self-esteem enhancement group program for women with disabilities. A sample of 19 racially and ethnically diverse, community-living women with physical disabilities, 22 to 61 years old, participated in a 7-session interactive group intervention (extending Hughes et al., 2004) in the 3-D, immersive, virtual environment of SecondLife.com, using avatars with voice and text communication. Baseline and postintervention questionnaires were administered online. Criteria for determining feasibility were (a) enrollment, (b) engagement, (c) acceptability, and (d) improvement on measures of self-esteem, depression, self-efficacy, and social support. We attained our enrollment goal and engagement exceeded expectations. Acceptability was positive; participants gave "helpful" and "enjoyable" ratings of 3.21 and 3.27, respectively, (mean on a 1 to 4 Likert scale, where 4 = high) to 5 intervention components-session materials, group sharing and discussion, relaxation exercises, action planning, and group excursions. Significant increases from baseline to postintervention were found on the Rosenberg Self-Esteem Scale (p = .02; Cohen's d = .60) and the Center for Epidemiologic Studies Depression Scale-10 (p = .005; Cohen's d = .74), with a trend toward significance on the Generalized Self-Efficacy Scale (p = .08; Cohen's d = .42). The intervention did not significantly affect the measure of social support. An intervention to enhance self-esteem may have a corollary benefit on depressive symptomatology. Offering psycho-educational, small group interventions using online virtual worlds shows promise for circumventing disability-related and environmental barriers to accessing mental health services experienced by women with mobility limitations, and should undergo further development and testing.

    Full Text Available Health education, which also includes medicine education, promotes social sustainability in society. Through the context of Internet-based intervention, this study reports on fourth graders’ (N = 51, aged 10–11 years perspectives on medicines, their use with common diseases and medicine-related information sources. The study was qualitative by nature. Data was collected in spring 2010, by audio recording students’ group discussions during the study process and group interviews. After intervention, students were well aware of the proper use of medicines and how to find information both on medicines and health issues. The main challenge was finding websites that provide reliable and confidential information. The results of this study raise awareness of a concrete pedagogical approach to health education. The pedagogical approach conducted in the intervention could, to some extent, be transferred to any school setting. This study underlies the promotion of Internet-based health literacy and criteria, for evaluating online health information in the primary school context.

    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.

    Although there is growing evidence of the positive effects of Internet-based patient-provider communication (IPPC) services for both patients and health care providers, their implementation into clinical practice continues to be a challenge. The 3 aims of this study were to (1) identify and compare barriers and facilitators influencing the implementation of an IPPC service in 5 hospital units using the Consolidated Framework for Implementation Research (CFIR), (2) assess the ability of the different constructs of CFIR to distinguish between high and low implementation success, and (3) compare our findings with those from other studies that used the CFIR to discriminate between high and low implementation success. This study was based on individual interviews with 10 nurses, 6 physicians, and 1 nutritionist who had used the IPPC to answer messages from patients. Of the 36 CFIR constructs, 28 were addressed in the interviews, of which 12 distinguished between high and low implementation units. Most of the distinguishing constructs were related to the inner setting domain of CFIR, indicating that institutional factors were particularly important for successful implementation. Health care providers' beliefs in the intervention as useful for themselves and their patients as well as the implementation process itself were also important. A comparison of constructs across ours and 2 other studies that also used the CFIR to discriminate between high and low implementation success showed that 24 CFIR constructs distinguished between high and low implementation units in at least 1 study; 11 constructs distinguished in 2 studies. However, only 2 constructs (patient need and resources and available resources) distinguished consistently between high and low implementation units in all 3 studies. The CFIR is a helpful framework for illuminating barriers and facilitators influencing IPPC implementation. However, CFIR's strength of being broad and comprehensive also limits its

    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.

    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)

    In New Zealand (NZ), 20% of adults report a disability, of which one-third is caused by injury. No prospective epidemiological studies of predictors of disability following all-cause injury among New Zealanders have been undertaken. Internationally, studies have focused on a limited range of predictors or specific injuries. Although these studies provide useful insights, applicability to NZ is limited given the importance of NZ's unique macro-social factors, such as NZ's no-fault accident compensation and rehabilitation scheme, the Accident Compensation Corporation (ACC). (1) To quantitatively determine the injury, rehabilitation, personal, social and economic factors leading to disability outcomes following injury in NZ. (2) To qualitatively explore experiences and perceptions of injury-related outcomes in face-to-face interviews with 15 Māori and 15 other New Zealanders, 6 and 12 months after injury. Four geographical regions within NZ. Prospective cohort study with telephone interviews 1, 4 and 12 months after injury. 2500 people (including 460 Māori), aged 18-64 years, randomly selected from ACC's entitlement claims register (people likely to be off work for at least 1 week or equivalent). Telephone interviews, electronic hospital and ACC injury data. Exposures include demographic, social, economic, work-related, health status, participation and/or environmental factors. Primary: disability (including WHODAS II) and health-related quality of life (including EQ-5D). Secondary: participation (paid and unpaid activities), life satisfaction and costs. Separate regression models will be developed for each of the outcomes. Repeated measures outcomes will be modelled using general estimating equation models and generalised linear mixed models.

    Psychiatric patients are at high risk of becoming victim of a violent crime compared to the general population. Although most research has focused on patients with severe mental illness, depressed patients have been demonstrated to be prone to victimization as well. Victimization is associated with more severe symptomatology, decreased quality of life, and high risk of revictimization. Hence, there is a strong need for interventions that focus on preventing violent revictimization. Since emotion dysregulation is associated with both victimization and depression, we developed an internet-based Emotion Regulation Training (iERT) to reduce revictimization in depressed patients. This study aims to evaluate the clinical and cost-effectiveness of iERT added to Treatment As Usual (TAU) in reducing incidents of violent revictimization among depressed patients with a recent history of victimization. Furthermore, this study aims to examine secondary clinical outcomes, and moderators and mediators that may be associated with treatment outcomes. In a multicenter randomized controlled trial with parallel group design, patients with a major depressive disorder and a history of violent victimization over the past three years (N = 200) will be allocated to either TAU + iERT (N = 100) or TAU only (N = 100), based on computer-generated stratified block randomization. Assessments will take place at baseline, 8 weeks, 14 weeks, and 6 months after start of treatment, and 12, 24, and 36 months after baseline. The primary outcome measure is the total number of violent victimization incidents at 12 months after baseline, measured with the Safety Monitor: an adequate self-report questionnaire that assesses victimization over the preceding 12 months. Secondary outcome measures and mediators include emotion dysregulation and depressive symptomatology. An economic evaluation with the societal perspective will be performed alongside the trial. This study is the first to

    Despite the health benefits of regular physical activity, most children are insufficiently active. Schools are ideally placed to promote physical activity; however, many do not provide children with sufficient in-school activity or ensure they have the skills and motivation to be active beyond the school setting. The aim of this project is to modify, scale up and evaluate the effectiveness of an intervention previously shown to be efficacious in improving children's physical activity, fundamental movement skills and cardiorespiratory fitness. The 'Internet-based Professional Learning to help teachers support Activity in Youth' (iPLAY) study will focus largely on online delivery to enhance translational capacity. The intervention will be implemented at school and teacher levels, and will include six components: (i) quality physical education and school sport, (ii) classroom movement breaks, (iii) physically active homework, (iv) active playgrounds, (v) community physical activity links and (vi) parent/caregiver engagement. Experienced physical education teachers will deliver professional learning workshops and follow-up, individualized mentoring to primary teachers (i.e., Kindergarten - Year 6). These activities will be supported by online learning and resources. Teachers will then deliver the iPLAY intervention components in their schools. We will evaluate iPLAY in two complementary studies in primary schools across New South Wales (NSW), Australia. A cluster randomized controlled trial (RCT), involving a representative sample of 20 schools within NSW (1:1 allocation at the school level to intervention and attention control conditions), will assess effectiveness and cost-effectiveness at 12 and 24 months. Students' cardiorespiratory fitness will be the primary outcome in this trial. Key secondary outcomes will include students' moderate-to-vigorous physical activity (via accelerometers), fundamental movement skill proficiency, enjoyment of physical education and

    Violence in families affects children. Exposure to violence is seen as child abuse. Figures show that about one third of children exposed to violence become victim or perpetrator in their adult life: known as intergenerational transmission. Violence also affects sexual and reproductive health. To prevent problems in adult life, children need help and support. However, while trying to protect their parents, children often do not seek help, or perceive the threshold as too high. Since almost all children of the current generation have access to the internet, an online intervention will make help better available for this target group. In 2011, an internet-based self-support method for children, adolescents and young adults exposed to family violence was developed in the Netherlands: "Feel the ViBe". The intervention was developed in close collaboration with the target group. This article describes the protocol of the RCT to study the effectiveness of this intervention. This study is a randomized controlled trial using the method of minimization to randomize the participants in two parallel groups with a 1:1 allocation ratio, being an intervention group, having access to "Feel the ViBe" and usual care (UC), and a control group, having access to minimally enhanced usual care (mEUC) followed by access to the intervention after twelve weeks. Outcomes are measured with questionnaires on PTSD symptoms, mental health and sexual and reproductive health. Routine Outcome Measurement (ROM) will be used to measure a direct effect of participating in the intervention. Data from a web evaluation questionnaire (WEQ), user statistics and qualitative analysis of online data will be used to support the findings. To compare results Cohen's d effect sizes will be used. A RCT and process evaluation will test effectiveness and provide information of how the effects can be explained, how the intervention meets the expectation of participants and which possible barriers and facilitators for

    This is a cross-sectional study. The purpose of this study is to evaluate the content of information available on the Internet regarding minimally invasive spine surgery (MISS). Patients look to the Internet for quick and accessible information on orthopedic procedures to help guide their personal decision making process regarding the care they receive. However, the quality of internet-based orthopedic education material varies significantly with respect to accuracy and readability. The top 50 results were generated from each of 3 search engines (Google, Yahoo!, and Bing) using the search term "minimally invasive spine surgery." Results were categorized by authorship type and evaluated for their description of key factors such as procedural benefits, risks, and techniques. Comparisons between search engines and between authorship types were done using the Freeman-Halton extension for the Fisher exact test. The content of websites certified by Health on the Net Foundation (HONcode) was compared with those not HONcode certified. Of the 150 websites and videos, only 26% were authored by a hospital or university, whereas 50% were by a private physician or clinic. Most resources presented some benefits of MISS (84%, 126/150), but only 17% presented risks of the procedure (26/150). Almost half of all resources described the technique of MISS, but only 27% had thorough descriptions that included visual representations while 26% failed to describe the procedure. Only 12 results were HONcode certified, and 10 (83%) of these were authored by a medical industry company. Internet-based resources on MISS provide inconsistent content and tend to emphasize benefits of MISS over risks.

    Introduction As a consequence of sepsis and intensive care, considerable proportions of patients but also of their spouses develop a post-traumatic stress disorder (PTSD). However, only a very small number receive psychotherapeutic treatment. Internet-based cognitive–behavioural writing therapy (IB-CBWT) has proven to be an effective treatment option for PTSD. It seems to fit the specific needs of this cohort and to overcome treatment barriers. Aim of the REPAIR trial is to examine the efficacy, safety and applicability of IB-CBWT for PTSD in patients and their spouses after intensive care for sepsis. Methods and analysis Participants will be assigned randomly either to a treatment or a wait-list (WL) control group. The treatment group receives IB-CBWT for PTSD, actively involving the partners of the participants. IB-CBWT will be guided by a therapist and comprises two written assignments per week over a 5 week period. After completing the assignments, the participants obtain individual responses from the therapist. Participants of the WL control group will receive treatment after a waiting period of 5 weeks. The primary outcome is PTSD symptom severity in self-rated PTSD Checklist for Diagnostic and Statistical Manual Fifth Edition at the end of treatment and waiting time, respectively. Secondary outcomes are remission of PTSD, depression, anxiety, and somatisation measured by the Brief Symptom Inventory-18, marital satisfaction measured by the Relationship Assessment Scale, health-related quality of life measured by the EQ-5D-5L, and the feasibility of IB-CBWT for this cohort (ie, dropout rate). Statistical analysis will be performed according to the intent-to-treat principle. Ethics and dissemination The study is conducted according to the principles of Good Clinical Practice and has been approved by the ethics committee of the Friedrich-Schiller University Jena, Germany. Results will be disseminated at scientific conferences, published in peer

    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.

    Rand, Debbie; Lee Ben-Haim, Keren; Malka, Rachel; Portnoy, Sigal

    The Executive Function Performance Test (EFPT) is a reliable and valid performance-based tool to assess executive functions (EFs). This study's objective was to develop and verify two Internet-based tasks for the EFPT. A cross-sectional study assessed the alternate-form reliability of the Internet-based bill-paying and telephone-use tasks in healthy adults and people with subacute stroke (Study 1). It also sought to establish the tasks' criterion reliability for assessing EF deficits by correlating performance with that on the Trail Making Test in five groups: healthy young adults, healthy older adults, people with subacute stroke, people with chronic stroke, and young adults with attention deficit hyperactivity disorder (Study 2). The alternative-form reliability and initial construct validity for the Internet-based bill-paying task were verified. Criterion validity was established for both tasks. The Internet-based tasks are comparable to the original EFPT tasks and can be used for assessment of EF deficits. Copyright © 2018 by the American Occupational Therapy Association, Inc.

    Adolescents and young adults (AYAs) are of special interest in a group of children exposed to family violence (FV). Past-year prevalence of exposure to FV is known to be highest in AYAs and has severe consequences. Peer support is an effective approach to behavior change and the Internet is considered suitable as a mode of delivery. The study aimed to evaluate both effectiveness and feasibility of a randomized controlled trial (RCT) and feasibility study of the Internet-based self-support method "Feel the ViBe" (FtV) using mixed-methods approach to fully understand the strengths and weaknesses of a new intervention. AYAs aged 12-25 years and exposed to FV were randomized in an intervention group (access to FtV + usual care) and a control group (minimally enhanced usual care) after they self-registered themselves. From June 2012 to July 2014, participants completed the Impact of Event Scale (IES) and Depression (DEP) and Anxiety (ANX) subscales of the Symptom CheckList-90-R (SCL-90) every 6 weeks. The Web Evaluation Questionnaire was completed after 12 weeks. Quantitative usage data were collected using Google analytics and content management system (CMS) logs and data files. A univariate analysis of variance (UNIANOVA) and mixed model analysis (intention-to-treat [ITT], complete case) were used to compare groups. Pre-post t tests were used to find within-group effects. Feasibility measures structurally address the findings. The CONsolidated Standards Of Reporting Trials of Electronic and Mobile HEalth Applications and onLine TeleHealth (CONSORT-EHEALTH) checklist was closely followed. In total, 31 out of 46 participants in the intervention group and 26 out of 47 participants in the control group started FtV. Seventeen participants (intervention: n=8, control: n=9) completed all questionnaires. Mixed model analysis showed significant differences between groups on the SCL-90 DEP (P=.04) and ANX (P=.049) subscales between 6 and 12 weeks after participation started

    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.

    Bronchiolitis is the most common lower respiratory infection in children under 2 years old. Respiratory syncytial virus (RSV) is the most frequently involved etiologic agent. To identify different viruses causing bronchiolitis and try to correlate them with demographic and clinical variables. To analyze diagnostic and therapeutic approache. We conducted a prospective study, between November 2008 and March 2009 (5 months), including children bronchiolitis. Screening for RSV, parainfluenza 1-3 and adenovirus used immunofluorescence tests and screening for influenza A and B, human metapneumovirus (MPvh), human bocavirus (hBoV) and RSV used polymerase chain reaction (PCR) techniques. Data were analysed by using SPSS®. We included 78 children with 8.5 months mean age (83% physiotherapy. Viral testing was positive in 59/75 children: RSV (69.3%), BoVh (22.7%), MPVh (4%), parainfluenza 3 (27%) and influenza A (2.6%). Co-infection with two viruses was detected in 23% of children. In 88% of children with positive samples for BoVh it has been detected RSV infection simultaneously. Children with co-infection (RSV + BoVh) required more often hospitalization compared with children infected with RSV alone (80% vs 60%, p=0.028), without significant differences in oxygen supplementation need and length of disease. RSV was the main etiologic agent and oxygen supplementation requirement justified the majority of hospitalizations. There was a high rate of co-infection with RSV and BoVh, but without longer disease. BoVh infection alone was uncommon.

  5. Internet-based learning and applications for critical care medicine.

    2012-01-01

    Recent changes in duty hour allowances and economic constraints are forcing a paradigm shift in graduate medical education in the United States. Internet-based learning is a rapidly growing component of postgraduate medical education, including the field of critical care medicine. Here, we define the key concepts of Internet-based learning, summarize the current literature, and describe how Internet-based learning may be uniquely suited for the critical care provider. A MEDLINE/PubMed search from January 2000 to July 2011 using the search terms: "e-learning," "Web-based learning," "computer-aided instruction," "adult learning," "knowledge retention," "intensive care," and "critical care." The growth of the Internet is marked by the development of new technologies, including more user-derived tools. Nonmedical fields have embraced Internet-based learning as a valuable teaching tool. A recent meta-analysis described Internet-based learning in the medical field as being more effective than no intervention and likely as efficacious as traditional teaching methods. Web sites containing interactive features are aptly suited for the adult learner, complementing the paradigm shift to more learner-centered education. Interactive cases, simulators, and games may allow for improvement in clinical care. The total time spent utilizing Internet-based resources, as well as the frequency of returning to those sites, may influence educational gains. Internet-based learning may provide an opportunity for assistance in the transformation of medical education. Many features of Web-based learning, including interactivity, make it advantageous for the adult medical learner, especially in the field of critical care medicine, and further work is necessary to develop a robust learning platform incorporating a variety of learning modalities for critical care providers.

  6. Neurocutaneous syndrome: A prospective study

    2011-01-01

    Full Text Available Background: Neurocutaneous syndromes (NCS are a group of genetic disorders that produce a variety of developmental abnormalities of the skin along with an increased risk of neurological complications. Cutaneous manifestations usually appear early in life and progress with time, but neurological features generally present at a later age. There is a paucity of data regarding the evolution of skin lesions and their correlation with the central nervous system involvement in children. Aim: The primary objective was to track the course of skin lesions in various forms of NCS in the pediatric age group. Our secondary aim was to assess whether there was any predictive value of the lesions in relation to the neurological manifestations. Materials and Methods: This prospective longitudinal study was conducted at a tertiary care pediatric dermatology referral clinic of the Institute of Child Health, Kolkata, West Bengal. Children between the age group 0 and 12 years were included in the study on the basis of standard diagnostic criteria for different NCS, during the period from March, 2000 to February, 2004, and each of the enrolled cases were followed up for a duration of six years. Results: The study population comprised of 67 children (35 boys, 32 girls.The mean age of presentation was 33.8±27.8 months (range 10 days to 111 months. The various forms of NCS observed was neurofibromatosis 1(NF1 (n=33, tuberous sclerosis complex (TSC (n=23, Sturge Weber syndrome (n=6, ataxia telangiectasia (n=2, PHACE syndrome (n=1, incontinentia pigmenti (n=1, and hypomelanosis of Ito (n=1. The presentations were varied, ranging from predominantly cutaneous to primarily neurological, depending on the disease entity and age group concerned. There was a significant increase in the number of café au lait macules (CALMs with time (P=0.0002 in NF1, unlike that of hypopigmented macules of TSC (P=0.15. Statistically, no relation was documented between the evolution of skin

    Internet-based cognitive behavior therapy (CBT) for severe health anxiety can be effective, but not all patients achieve full remission. Under these circumstances, knowledge about predictors is essential for the clinician in order to make reliable treatment recommendations. The primary aim of this study was to investigate clinical, demographic, and therapy process-related predictors of Internet-based CBT for severe health anxiety. We performed three types of analyses on data from a sample comprising participants (N = 81) who had received Internet-based CBT in a randomized controlled trial. Outcomes were a) end state health anxiety, b) improvement in health anxiety (continuous change scores), and c) clinically significant improvement. Outcomes were assessed at six-month follow-up. The results showed that the most stable predictors of both end state health anxiety and improvement were baseline health anxiety and depressive symptoms. Treatment adherence, i.e. the number of completed treatment modules, also significantly predicted outcome. Notably, health anxiety at baseline was positively associated with symptom improvement while depressive symptoms was negatively related to improvement. Demographic factors were largely without significant impact on end state symptoms or improvement. We conclude that baseline symptom burden and adherence to treatment have strong predictive effects in Internet-based CBT for severe health anxiety. Copyright © 2013 Elsevier Ltd.

    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.

    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

    Full Text Available Abstract Background The management of Whiplash Associated Disorders is one of the most complicated challenges with high expenses for the health care system and society. There are still no general guidelines or scientific documentation to unequivocally support any single treatment for acute care following whiplash injury. The main purpose of this study is to try a new behavioural medicine intervention strategy at acute phase aimed to reduce the number of patients who have persistent problems after the whiplash injury. The goal is also to identify which of three different interventions that is most cost-effective for patients with Whiplash Associated Disorders. In this study we are controlling for two factors. First, the effect of behavioural medicine approach is compared with standard care. Second, the manner in which the behavioural medicine treatment is administered, Internet or face-to-face, is evaluated in it's effectiveness and cost-effectiveness. Methods/Design The study is a randomized, prospective, experimental three-group study with analyses of cost-effectiveness up to two-years follow-up. Internet – based programme and face-to-face group treatment programme are compared to standard-treatment only. Patient follow-ups take place three, six, twelve and 24 months, that is, short-term as well as long-term effects are evaluated. Patients will be enrolled via the emergency ward during the first week after the accident. Discussion This new self-help management will concentrate to those psychosocial factors that are shown to be predictive in long-term problems in Whiplash Associated Disorders, i.e. the importance of self-efficacy, fear of movement, and the significance of catastrophizing as a coping strategy for restoring and sustaining activities of daily life. Within the framework of this project, we will develop, broaden and evaluate current physical therapy treatment methods for acute Whiplash Associated Disorders. The project will

    2009-12-01

    Social networking sites such as MySpace and virtual communities such as on-line support groups can be a rich source of data for researchers. These sites can be an effective way of reaching and researching young people in order to address their particular health needs. Internet-based research is also potentially risky and exploitative. There is some guidance for conducting research online, but there are no detailed or universally accepted ethics guidelines for research of webspaces such as MySpace or virtual communities in which young people participate. One question that arises is--If MySpace is a public webspace, can research be done without consent? In this paper I investigate ethical issues surrounding young people's consent in cyber research. I identify issues that help determine whether consent is needed, offer suggestions for dealing with consent in cyberspace and add my voice to the call for a resource of case studies--indispensible in the development of guidelines and the education of researchers and research ethics committees.

  15. 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.

    Full Text Available Abstract Background Educational courses for doctors and medical students are increasingly offered via the Internet. Despite much research, course developers remain unsure about what (if anything to offer online and how. Prospective learners lack evidence-based guidance on how to choose between the options on offer. We aimed to produce theory driven criteria to guide the development and evaluation of Internet-based medical courses. Methods Realist review - a qualitative systematic review method whose goal is to identify and explain the interaction between context, mechanism and outcome. We searched 15 electronic databases and references of included articles, seeking to identify theoretical models of how the Internet might support learning from empirical studies which (a used the Internet to support learning, (b involved doctors or medical students; and (c reported a formal evaluation. All study designs and outcomes were considered. Using immersion and interpretation, we tested theories by considering how well they explained the different outcomes achieved in different educational contexts. Results 249 papers met our inclusion criteria. We identified two main theories of the course-in-context that explained variation in learners' satisfaction and outcomes: Davis's Technology Acceptance Model and Laurillard's model of interactive dialogue. Learners were more likely to accept a course if it offered a perceived advantage over available non-Internet alternatives, was easy to use technically, and compatible with their values and norms. 'Interactivity' led to effective learning only if learners were able to enter into a dialogue - with a tutor, fellow students or virtual tutorials - and gain formative feedback. Conclusions Different modes of course delivery suit different learners in different contexts. When designing or choosing an Internet-based course, attention must be given to the fit between its technical attributes and learners' needs and

    The increasing use of Internet-based learning in health professions education may be informed by a timely, comprehensive synthesis of evidence of effectiveness. To summarize the effect of Internet-based instruction for health professions learners compared with no intervention and with non-Internet interventions. Systematic search of MEDLINE, Scopus, CINAHL, EMBASE, ERIC, TimeLit, Web of Science, Dissertation Abstracts, and the University of Toronto Research and Development Resource Base from 1990 through 2007. Studies in any language quantifying the association of Internet-based instruction and educational outcomes for practicing and student physicians, nurses, pharmacists, dentists, and other health care professionals compared with a no-intervention or non-Internet control group or a preintervention assessment. Two reviewers independently evaluated study quality and abstracted information including characteristics of learners, learning setting, and intervention (including level of interactivity, practice exercises, online discussion, and duration). There were 201 eligible studies. Heterogeneity in results across studies was large (I(2) > or = 79%) in all analyses. Effect sizes were pooled using a random effects model. The pooled effect size in comparison to no intervention favored Internet-based interventions and was 1.00 (95% confidence interval [CI], 0.90-1.10; P Internet formats, the pooled effect sizes (positive numbers favoring Internet) were 0.10 (95% CI, -0.12 to 0.32; P = .37; n = 43) for satisfaction, 0.12 (95% CI, 0.003 to 0.24; P = .045; n = 63) for knowledge, 0.09 (95% CI, -0.26 to 0.44; P = .61; n = 12) for skills, and 0.51 (95% CI, -0.24 to 1.25; P = .18; n = 6) for behaviors or patient effects. No important treatment-subgroup interactions were identified. Internet-based learning is associated with large positive effects compared with no intervention. In contrast, effects compared with non-Internet instructional methods are heterogeneous and

  2. Internet-based screening for dementia risk.

    Directory of Open Access Journals (Sweden)

    Jason Brandt

    Full Text Available The Dementia Risk Assessment (DRA is an online tool consisting of questions about known risk factors for dementia, a novel verbal memory test, and an informant report of cognitive decline. Its primary goal is to educate the public about dementia risk factors and encourage clinical evaluation where appropriate. In Study 1, more than 3,000 anonymous persons over age 50 completed the DRA about themselves; 1,000 people also completed proxy reports about another person. Advanced age, lower education, male sex, complaints of severe memory impairment, and histories of cerebrovascular disease, Parkinson's disease, and brain tumor all contributed significantly to poor memory performance. A high correlation was obtained between proxy-reported decline and actual memory test performance. In Study 2, 52 persons seeking first-time evaluation at dementia clinics completed the DRA prior to their visits. Their responses (and those of their proxy informants were compared to the results of independent evaluation by geriatric neuropsychiatrists. The 30 patients found to meet criteria for probable Alzheimer's disease, vascular dementia, or frontotemporal dementia differed on the DRA from the 22 patients without dementia (most other neuropsychiatric conditions. Scoring below criterion on the DRA's memory test had moderately high predictive validity for clinically diagnosed dementia. Although additional studies of larger clinical samples are needed, the DRA holds promise for wide-scale screening for dementia risk.

    The Dementia Risk Assessment (DRA) is an online tool consisting of questions about known risk factors for dementia, a novel verbal memory test, and an informant report of cognitive decline. Its primary goal is to educate the public about dementia risk factors and encourage clinical evaluation where appropriate. In Study 1, more than 3,000 anonymous persons over age 50 completed the DRA about themselves; 1,000 people also completed proxy reports about another person. Advanced age, lower education, male sex, complaints of severe memory impairment, and histories of cerebrovascular disease, Parkinson's disease, and brain tumor all contributed significantly to poor memory performance. A high correlation was obtained between proxy-reported decline and actual memory test performance.

    The identification of individuals who are at high risk of dementia may lead to earlier detection and diagnosis. In this study, we describe the development and preliminary validation of a very brief, Internet-based risk assessment tool. The Dementia Risk Assessment collected information on demographic, neurologic, and medical risk factors; perceived cognitive functioning; and emotional symptoms. Participants answered questions pertaining to themselves ("patient page") or to a relative or friend ("proxy page"). Patients also completed a novel short-delayed recognition memory test. Subjects received personalized feedback about their risk factors and were advised to seek clinical evaluation for concerning symptoms. By November 2009, 500 respondents completed the patient page. The 352 respondents aged 50 years or older (M = 62 years) included a high percentage of women (72%) and college graduates (67%). Among the respondents, only 10% complained of having severe memory problems, whereas 38% reported having a first-degree relative who experienced severe memory loss. The prevalence of major neurologic risk factors was low. Although the delay interval for the recognition memory test averaged around 2 minutes, there was sufficient variability in performance. Individuals with scores ≤10th percentile were significantly older and more likely to be men, have hypertension, and report having severe memory problems. History of major dementia risk factors can be ascertained through the Internet, and several of these factors are shown to be moderately predictive of performance on a brief test of episodic memory. These data provide preliminary validation of the Dementia Risk Assessment for identifying current cognitive impairment, and suggest its potential for assessing future dementia risk. Ongoing studies will further establish the validity of these findings against proxy reports of cognitive and functional decline, the results of more detailed cognitive assessments, and formal

    The Boeing prospective study was reviewed. The Boeing prospective study, comprising two articles, was a large field study that explored why workers would or would not report occupational back pain problems. The most immediate objective was to determine the extent to which conclusions drawn from the Boeing prospective study withstand critical examination. The ultimate purpose of this review was to develop guidelines for field studies of back pain in industry. For more than a century, researchers have noted great variability among individuals in the reporting of back pain, but the explanations posed for this variability have been inconsistent. Because findings gain credibility roughly to the extent that they bear on the world outside the laboratory, field studies in particular hold great potential for clarifying the underlying explanation for individual variability in back pain reporting. The Boeing prospective study was a large and ambitious field study that examined this issue. The Boeing prospective study was examined through the lens of research conducted since it was published. The review used both the methodological and substantive literature. The Boeing prospective study, based on a minority of workers originally solicited to participate in it (33-41%), accounted for 7% of the variation in why workers would or would not report a back pain problem. A number of issues that may have biased its results toward the null are examined. The highlighting of the Boeing prospective study's limitations may be instructive not so much to criticize this one particular study but, rather, to anticipate problems that in general may be encountered in field studies of back pain in industry. Looking beyond the Boeing prospective study, the following guidelines for the conduct of such studies may be proposed: 1) Study designs should be based on explanations from which testable hypotheses may be derived; 2) Subgroups within the more general category of "back pain" should be

    Conclusions: Guidance is a beneficial feature of Internet-based interventions, although its effect is smaller than reported before when compared to unguided interventions. The qualification of the e-coaches seems of minor importance. However, methodological limitations need to be considered when interpreting these findings. Overall, the number of studies was small and mainly limited to depression and social phobia restricting the generalizability of the findings.

    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. 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. 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. 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. 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. © 2014 Sigma Theta Tau International.

    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.

    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.

    Internet-based screening for vaginal sexually transmitted infections (STI) has been shown to reach high-risk populations. Published studies of internet-based screening for rectal STIs in women are needed. Our objectives were to describe the female users of a rectal internet-based screening intervention and assess what factors correlated with rectal positivity for STIs. The website http://www.iwantthekit.org offers free STI testing via home self-sampling kits. Women could order vaginal and rectal kits, both containing questionnaires. Rectal and vaginal swabs were tested for Chlamydia trachomatis, Neisseria gonorrhoeae and Trichomonas vaginalis using nucleic acid amplification tests. Data were analysed from 205 rectal kits from January 2009 through February 2011. Self-reported characteristics of participants were examined, and correlates of rectal STI positivity were analysed. Of the 205 rectal samples returned and eligible for testing, 38 (18.5%) were positive for at least one STI. The women were young (mean age 25.8 years), mostly African-American (50.0%), and only 14.0% always used condoms. After adjusting for age and race, Black race (AOR=3.06) and vaginal STI positivity (AOR=40.6) were significantly correlated with rectal STI positivity. Of women testing positive for rectal STIs who also submitted vaginal swabs, 29.4% were negative in the vaginal sample. Internet-based rectal screening can reach populations that appear to be at high risk for rectal STIs (18.5% prevalence) and led to the diagnosis of STIs in women who would not have been diagnosed vaginally. Black race and vaginal STI positivity were highly correlated with rectal STI positivity. Published by the BMJ Publishing Group Limited.

    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.

    When trying to access interventions to improve their well-being and quality of life, family caregivers face many challenges. Internet-based interventions provide new and accessible opportunities to remotely support them and can contribute to reducing their burden. However, little is known about the link existing between the components, the use of behavior change techniques, and the outcomes of these Internet-based interventions. This study aimed to provide an update on the best available evidence about the efficacy of Internet-based interventions for caregivers of older adults. Specifically, the components and the use of behavior change techniques and how they impact on the efficacy of the intervention were sought. A systematic review searched primary source studies published between 2000 and 2015. Included studies were scored with a high level of evidence by independent raters using the GRADE criteria and reported caregiver-specific outcomes about interventions delivered through the Internet for caregivers of people aged 50 years and older. A narrative synthesis identified intervention components (eg, content, multimedia use, interactive online activities, and provision of support), behavior change techniques, and caregiver outcomes (eg, effects on stressors, mediators, and psychological health). The risk of bias within the included studies was assessed. A total of 2338 articles were screened and 12 studies describing 10 Internet-based interventions were identified. Seven of these interventions led to statistically significant improvements in caregiver outcomes (eg, reducing depression or anxiety, n=4). These efficacious interventions used interactive components, such as online exercises and homework (n=4) or questionnaires on health status (n=2) and five of them incorporated remote human support, either by professionals or peers. The most frequently used behavior change techniques included in efficacious interventions were provision of social support (n=6) and

    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.

    Despite effective treatment approaches, relapses are frequent in eating disorders. Posttreatment care is essential to enhance continuous recovery and prevent deterioration. This study evaluated the effects of an Internet-based intervention following routine care. One hundred five women who received treatment for bulimia nervosa and related eating disorders not otherwise specified were randomly assigned either to an immediate Internet-based support program (EDINA) over 4 months or to a 4-month waiting-list treatment as usual (TAU) control condition. The primary outcome was eating disorder-related attitudes at baseline and after 4 months assessed by the Eating Disorder Examination Questionnaire (EDE-Q). The program proved feasible and was well accepted. A significant reduction in eating disorder-related attitudes could be shown for both groups at the end of the 4 months. There was a tendency for participants of the aftercare intervention to show better results on all outcome measures. In total, 40.6% (13/32) of the EDINA participants and 24.4% (10/41) of the TAU participants showed statistically reliable improvement on the EDE-Q total score by the end of the intervention period [χ(2)(1)=2.195, p=0.138]. The Internet-based support program was feasible and well accepted but did not prove efficacious in a heterogeneous sample of patients following routine care.

    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.

    Physical activity promotes health in children and adolescents, but activity levels are low. The Internet offers opportunities for physical activity interventions because children and adolescents are widely exposed to the web and enjoy being online. This review investigated the success of Internet-based interventions designed to increase physical activity in children and adolescents. Of the 13 studies we included, five reported that Internet-based interventions had significant effects on most physical activities. Internet-based physical activity interventions in children and adolescents are potentially successful, but interdisciplinary, child-centred collaboration is needed to design interventions that align with their Internet experiences and preferences. ©2015 Foundation Acta Paediatrica.

    The objective of this paper is to investigate the experiences of using a digital marketing platform to promote the use of an internet based health encyclopedia in Saudi Arabia. Key informant interviews, meeting documentation, and Google Analytics were the data collection sources used in the study. Findings show that using a digital marketing platform led to a significant increase in the number of visitors to the health encyclopedia. The results demonstrate that digital marketing platforms are effective tools to be used for promoting internet based health education interventions. Future work will examine long-term educational impacts and costs in using digital marketing platforms to promote online healthcare sites in Saudi Arabia.

    A total of 162 participants were included in the study and 94 and 84 participants completed the post and follow-up measurements respectively. Participants in all conditions improved significantly on the main outcome measures, and the different levels of Presentation or therapist Support did not significantly affect treatment outcome. Registered number of completed exercises was a predictor of better treatment outcome, but this effect was independent of treatment condition. Enhancing internet based interventions by improving presentations and the quality of support may thus not be the best way to further improve the effect of internet based interventions. More specific knowledge of the mechanisms that affect outcomes in online psychotherapy is needed.

    Obsessive-compulsive disorder (OCD) is a disabling anxiety disorder, but most individuals delay seeking treatment. Internet-based cognitive behavioural therapy (iCBT) is an innovative service delivery method that may help to improve access to care, but the acceptability to consumers of such programs has not yet been established. People with symptoms of OCD were invited to complete an online survey enquiring about demographic characteristics, symptom severity, and acceptability of Internet-based treatment. Demographic and symptom severity data were compared with people with OCD identified in a national epidemiological survey and with a sample of patients with OCD from a specialist outpatient anxiety clinic. 129 volunteers to an online Internet survey, 135 patients at a specialist anxiety disorders outpatient clinic, and 297 cases identified in a national epidemiological survey. Demographic characteristics, and severity of symptoms as measured by the Kessler 10-Item scale, the 12-item World Health Organisation Disability Assessment Schedule-Second Edition and the Yale Brown Obsessive Compulsive Scale-Self Report Version. The Internet sample was similar demographically but reported more severe symptoms than the comparison groups, although had similar severity of symptoms of OCD compared with other clinical samples reported in the literature. Participants reported Internet-based treatment for OCD would be highly acceptable. Internet-based treatment may reduce barriers to accessing treatment to people with OCD. Individuals in this study were similar demographically to other samples and had similar severity of symptoms as those identified in other clinical samples, suggesting that Internet-based treatment using techniques employed in face-to-face treatment may be effective in this group. Internet-based treatments for OCD need to be developed and evaluated.

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.

    The majority of internet-based anxiety and depression intervention studies have targeted adults. An increasing number of studies of children, youth, and young adults have been conducted, but the evidence on effectiveness has not been synthesized. The objective of this research is to systematically review the most recent findings in this area and calculate overall (pooled) effect estimates of internet-based anxiety and/or depression interventions. We searched five literature databases (PubMed, EMBASE, CINAHL, PsychInfo, and Google Scholar) for studies published between January 1990 and December 2012. We included studies evaluating the effectiveness of internet-based interventions for children, youth, and young adults (age internet-based intervention vs. waitlist control and internet-based intervention vs. face-to-face intervention. We also calculated pooled remission rate ratio and 95% CI. We included seven studies involving 569 participants aged between 7 and 25 years. Meta-analysis suggested that, compared to waitlist control, internet-based interventions were able to reduce anxiety symptom severity (standardized mean difference and 95% CI = -0.52 [-0.90, -0.14]) and increase remission rate (pooled remission rate ratio and 95% CI =3.63 [1.59, 8.27]). The effect in reducing depression symptom severity was not statistically significant (standardized mean difference and 95% CI = -0.16 [-0.44, 0.12]). We found no statistical difference in anxiety or depression symptoms between internet-based intervention and face-to-face intervention (or usual care). The present analysis indicated that internet-based interventions were effective in reducing anxiety symptoms and increasing remission rate, but not effective in reducing depression symptom severity. Due to the small number of higher quality studies, more attention to this area of research is encouraged. PROSPERO registration: CRD42012002100.

  12. Generating Explanations for Internet-based Business Games

    2007-06-01

    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.

    Conducting and analyzing clinical studies of cough and cold medications is challenging due to the rapid onset and short duration of the symptoms. The use of Internet-based surveillance tools is a new approach in clinical studies that is gradually becoming popular and may become a useful method of recruitment. As part of an initiative to assess the safety and efficacy of cough and cold ingredients in children 6-11 years of age, a surveillance program was proposed as a means to identify and recruit pediatric subjects for clinical studies. The objective of the study was to develop an Internet-based surveillance system and to assess the feasibility of using such a system to recruit children for common cold clinical studies, record the natural history of their cold symptoms, and determine the willingness of parents to have their children participate in clinical studies. Healthy potential subjects were recruited via parental contact online. During the 6-week surveillance period, parents completed daily surveys to record details of any cold symptoms in their children. If a child developed a cold, symptoms were followed via survey for 10 days. Additional questions evaluated the willingness of parents to have their children participate in a clinical study shortly after onset of symptoms. The enrollment target of 248 children was reached in approximately 1 week. Children from 4 distinct geographic regions of the United States were recruited. Parents reported cold symptoms in 163 children, and 134 went on to develop colds. The most prevalent symptoms were runny nose, stuffed-up nose, and sneezing. The most severe symptoms were runny nose, stuffed-up nose, and sore/scratchy throat. The severity of most symptoms peaked 1-2 days after onset. Up to 54% of parents expressed willingness to bring a sick child to a clinical center shortly after the onset of symptoms. Parents found the Internet-based surveys easy to complete. Internet-based surveillance and recruitment can be useful

    To evaluate quality and readability of Internet-based information on halitosis. An Internet search through 3 engines (Google, Yahoo, and Bing) was done with the terms ("bad breath," "halitosis," "oral malodor," "foul breath," "mouth malodor," "breath malodor," "fetor ex ore," "fetor oris," "ozostomia," and "stomatodysodia"). The first 50 websites from each engine resulting from each search term were screened. Included websites were evaluated using Health on the Net (HON) criteria, Journal of American Medical Association (JAMA) benchmarks, DISCERN, Ensuring Quality Information for Patients (EQIP), Flesch Reading Ease (FRE) score, and Flesch-Kincaid Grade level. A total of 101 websites were included. HON, DISCERN, EQIP, and FRE score were 42.9%, 37.6%, 37.4%, and 51.9% of the maximum score, respectively. Fewer than 50% of sites displayed attribution, disclosure, and currency according to JAMA benchmarks. HON score, DISCERN score, and EQIP score had significant correlation with each other and were significantly higher in sites displaying the HON seal. The current quality and readability of informative websites on halitosis are generally low and poorly organized. Clinicians should be able to assess the Internet-based information on halitosis, as well as give accurate advice and guide patients concerning this issue. Copyright © 2017 Elsevier Inc.

    In the past decade, the use of internet-based cognitive behavioral treatments (internet-based CBT) for a wide range of patients has grown intensively. Incorporating the patients' opinions and perspective into new health care innovations might improve the quality and applicability of these innovations, as high dropout rates and low attrition are the often-reported concerns in E-health research. Most studies to date have examined patient perspectives on specific internet-based interventions that patients had participated in, and not the views of the general public. The current paper explores the perspective of patients with rheumatoid arthritis and psoriasis on internet-based CBT for these patient groups. In total, 100 patients (55 % male) participated in a semi-structured telephone interview about internet-based CBT, including questions about possible advantages and disadvantages and the readiness to participate in this kind of treatment. Most patients (78 %) were prepared to participate in internet-based CBT. Patients endorsed the advantages (57 %) more often than the disadvantages (34 %). The ease of internet-based CBT and the time saved were especially appealing to patients. Main disadvantages according to patients are that not all patients will be reached due to computer illiteracy and the lack of face-to-face interaction with the therapist. The results suggest that, from the patients' perspective, internet-based CBT is a promising health care development. Further research into aspects such as therapist interaction and enhancing computer literacy might contribute to an effective way of E-health care delivery in the future.

    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.

    The internet-based assessment of response time (RT) and error rate (ERR) has recently become a well-validated alternative to traditional laboratory-based assessment, because methodological research has provided evidence for negligible setting- and setup-related differences in RT and ERR measures of central tendency. However, corresponding data on potential differences in the variability of such performance measures are still lacking, to date. Hence, the aim of this study was to conduct internet-based mental chronometry in both poorly standardized domestic and highly standardized laboratory environments and to compare the variabilities of the corresponding performance measures. Using the Millisecond Inquisit4Web software, 127 men and women completed three different RT-based cognitive paradigms (i.e., go/no-go, two-back, and number-letter). Each participant completed all paradigms in two environments (i.e., at home and in the laboratory), with a time lag of seven days and in a counterbalanced order. Mixed-effects modeling was employed to estimate the between-setting variability across a comprehensive set of performance measures, including conventional measures of central tendency (i.e., mean RT and ERR) and further measures characterizing the joint distribution of RT/ERR. The latter measures were estimated using the diffusion model. The results suggested negligible differences between the domestic and laboratory settings. Thus, this study provides novel evidence suggesting that the statistical power of internet-based mental chronometry is commonly not compromised by increased environmental variance. The within- and between-session reliabilities were in a satisfactory range-that is, comparable to performance measures collected offline in laboratory settings. In consequence, our results support the broad applicability, robustness, and cost efficiency of mental chronometry assessment using the internet.

    The prevalence of overweight and obesity is increasing worldwide at an alarming rate. An Internet-based weight-loss programme has the potential to reach larger numbers of people than traditional face-to-face programmes. A growing body of evidence supports the use of low glycaemic load (GL) diets for weight loss. The present study aimed to investigate the efficacy of an Internet-based weight-loss programme that included foods with a low GL. One hundred and three volunteers, with a body mass index (BMI) ≥28 kg m(-2) , enrolled into an Internet weight-loss programme. A dietitian counselled participants over the Internet via weekly interactive chat rooms and monthly e-mails. Participants self-recorded body weight and food intake directly on to the Internet site. Weight, BMI and waist circumference were measured, and dietary data collected, at baseline and 6 months. Seventy participants completed the 6-month weight-loss programme. Among these, mean weight, BMI and waist circumference significantly decreased by 3.5 kg (95% CI = 2.3-4.7), 1.2 kg m(-2) (95% CI = 0.8-1.7) and 4.8 cm (95% CI = 2.8-6.8), of baseline values respectively (P 5% of initial body weight). This descriptive study has shown that an Internet-based weight-loss programme with low GL principles can promote weight loss. This type of intervention and approach could be used to enhance other weight-loss strategies. © 2010 The Authors. Journal compilation © 2010 The British Dietetic Association Ltd.

    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

    We studied the learning preferences of 160 respiratory specialists from four European countries who participated in ten internet-based learning modules and answered linked survey questions. Specialists were enthusiastic for internet learning amongst all national groups and particularly wanted to access material for teaching others. The value of social interactive learning was acknowledged but British and German subjects appeared more reluctant to participate. Internet delivered distance learning is well perceived amongst respiratory specialists. There is potential for both individual and group learning that could be realized by developing Europe-wide continuing professional development communities.

    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 psychology course.

    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.

    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.

    This study offers data about the efficacy of "Talk to Me," an Internet-based telepsychology program for the treatment of fear of public speaking that includes the most active components in cognitive-behavior therapy (CBT) for social phobia (exposure and cognitive therapies). One hundred twenty-seven participants with social phobia were randomly assigned to three experimental conditions: (a) an Internet-based self-administered program; (b) the same program applied by a therapist; (c) a waiting-list control group. Results showed that both treatment conditions were equally efficacious. In addition, Talk to Me and the same treatment applied by a therapist were more efficacious than the waiting-list condition. Treatment gains were maintained at 1-year follow-up. The results from this study support the utility of Internet-delivered CBT programs in order to reach a higher number of people who could benefit from CBT. Internet-delivered CBT programs could also play a valuable role in the dissemination of CBT.

    Obesity is a worldwide disease affecting 13% of the world's adult female population. The reasons and the fetal risk are still unclear. The effect of weight loss as a result of bariatric surgery seems to induce an improvement in fertility in obese women. The main purpose of this prospective study is to demonstrate if there is an association between bariatric surgery-induced weight loss and an improvement in the fertility of women at reproductive age. From June 2013 to April 2016, all bariatric female patients from our institutes were prospectively evaluated for suitability in this study. A pool of 52 eligible patients was extracted from our database in the recruitment period. Of these, 28 underwent bariatric surgery and 24 did not. Both groups were observed for two-year follow-up. During follow-up, anthropometrics parameters, blood analysis, and comorbidities were checked and a gynaecological consultation was prescribed. Fifty participants were studied. Twenty-seven successfully underwent bariatric surgery with a percentage of excess weight loss (EWL) >70% at 24 months, while 23 accepted the observation and control for 24 months as an integral part of the pre-surgical bariatric program. The contingency table analysis showed an extremely significant association (Pbariatric surgery) and event (pregnancy), with a relative risk (RR) = 15.33 and confidence interval (CI) 95%=2.213 to 106.26. Bariatric surgery improves fertility in obese women at two years' postoperative. Every obese woman with difficulties becoming pregnant should undergo a bariatric surgery consultation. Further studies are necessary to confirm our results.

    The purpose of the present study was to evaluate whether improvement in physical activity of students following a 4-month intervention of a university course was maintained 8 months later. Data on 77 students who responded to our scheduled inquiries completely through 1 year were analyzed. Participants of the intervention group (n=49) using the internet-based physical activity program exhibited significant increases in energy expenditures measured by IPAQ compared with the no-treatment control group (n=28) through 1 year. Participants who did not engage in regular university sports activities (baseline: 450±351kcalday(-1); post: 587±320kcalday(-1); 8-month follow-up: 580±394kcalday(-1)) only exhibited significant increases in energy expenditures compared with those of the control group (baseline: 498±341kcalday(-1); post: 414±242kcalday(-1); 8-month follow-up: 347±275kcalday(-1)). These results suggested that an internet-based interactive intervention could become a helpful tool in promoting and maintaining physical activity in the long term.

Evaluate the feasibility and effectiveness of an Internet-based psychological intervention treating comorbid mood disorder in adults with spinal cord injury (SCI). Improved mood and satisfaction with life were primary outcomes. Victoria, Australia. Electronic Personal Administration of Cognitive Therapy (ePACT). Depression, Anxiety and Stress Scale-Short Form (DASS21), Personal Well-being Index, Helplessness subscale of the Spinal Cord Lesion Emotional Well-being Scale v1 Australia, at each time point.Participant qualifying criteria:Adults (18-70 years), chronic SCI, attend SCI review clinic at Austin or Caulfield Hospital and score above normative threshold of the Depression, Anxiety and Stress Scale-Short Form (DASS21). Forty-eight participants completed Time 2 post intervention (n=23) or time equivalent for waitlist control group (n=25) telephone interviews. The measures were repeated a third time (Time 3) for a small subgroup (n=12) at 6 months post intervention within the study implementation time frame. Univariate within group analyses revealed significant improvement in mood in the intervention group at Time 2: (lower depression (effect size (ES)=0.4), anxiety (ES=0.4) and stress (ES=0.3)) and higher satisfaction with life (ES=0.2). Waitlist control group improved in depression only (ES=0.3) by Time 2. Multilevel variance components analyses, although not as positive, were still encouraging. Improvement in mood symptoms was maintained in the small group reinterviewed at Time 3. Although Internet-based interventions for mental health issues in SCI not a solution for all, our results indicate that they are a potentially valuable addition to the currently available options.

    Increasing HIV testing among men who have sex with men (MSM) is a major policy goal in the UK. Social marketing is a common intervention to increase testing uptake. We used an online panel of MSM to examine rates of HIV testing behaviour and the impact of a social marketing intervention on them. MSM in England were recruited to a longitudinal internet panel through community websites and a previous survey. Following an enrolment survey, respondents were invited to self-complete 13 surveys at monthly intervals throughout 2011. A unique alphanumeric code linked surveys for individuals. Rates of HIV testing were compared relative to prompted recognition of a multi-part media campaign aiming to normalise HIV testing. Of 3386 unique enrolments, 2047 respondents were included in the analysis, between them submitting 15,353 monthly surveys (equivalent to 1279 years of follow-up), and recording 1517 HIV tests taken, giving an annual rate of tests per participant of 1.19 (95% CI 1.13 to 1.25). Tests were highly clustered in individuals (61% reported no test during the study). Testing rates were higher in London, single men and those aged 25-34 years. Only 7.6% recognised the intervention when prompted. After controlling for sociodemographic characteristics and exposure to other health promotion campaigns, intervention recognition was not associated with increased likelihood of testing. Higher rates of testing were strongly associated with higher number of casual sexual partners and how recently men had HIV tested before study enrolment. This social marketing intervention was not associated with increased rates of HIV testing. More effective promotion of HIV testing is needed among MSM in England to reduce the average duration of undiagnosed infection. Published by the BMJ Publishing Group Limited.

    In an effort to reduce preventable injuries resulting from family fireworks displays, the Explosives Regulatory Division of Natural Resources Canada is developing a client service regulatory package - EXPLONET - which will be made available on the Internet. EXPLONET includes several components which address industry and public concerns. The initial component described here is the family educational safety module, designed to deal with the safe use of family fireworks. The objective is to reduce injuries to elementary school-age children through the delivery of an Internet-based lesson plan. The lesson plan is expected to be implemented on a pilot program basis to reach the target audience during the 1998 Halloween season when the use of fireworks is high. The lesson plan consists of four units and will be delivered over a period of four weeks prior to Hallo wen. Students will be active participants in the web-based sessions. The sessions will cover off-aspects of mathematics, history and science clustered around the central theme of fireworks safety, presented in a way to keep the children interested. The lesson will also include follow-up queries after Hallo wen, providing the children (and teachers) the opportunity to comment on what they have learned, and to identify product or safety improvements. Provision is also made for parent involvement. The module will be implemented on a pilot project basis in two schools, one in Nova Scotia and one in British Columbia. 6 refs., 1 tab., 10 figs.

    2017-01-01

    Background Major depressive disorders are common among adolescents and can impact all aspects of their daily life. Traditional therapies, cognitive behavioral therapy (CBT), and interpersonal psychotherapy (IPT) have been delivered face-to-face. However, Internet-based (online) delivery of these therapies is emerging as an option for adolescents. Internet-based CBT and IPT involve therapeutic content, interaction between the user and the system, and different technological features embedded into the online program (eg, multimedia). Studies of Internet-based CBT and IPT for adolescent depression differ on all three aspects, and variable, positive therapy effects have been reported. A better understanding of the treatment conditions that influence therapy outcomes is important to designing and evaluating these novel therapies. Objective Our aim was to examine the technological and program delivery features of Internet-based CBT and IPT for adolescent depression and to document their potential relation to treatment outcomes and program use. Methods We performed a realist synthesis. We started with an extensive search of published and gray literature. We included intervention studies that evaluated Internet-based CBT or IPT for adolescent depression. We included mixed-methods and qualitative studies, theoretical papers, and policy/implementation documents if they included a focus on how Internet-based psychological therapy is proposed to work for adolescents with depression/depressive symptoms. We used the Mixed-Methods Appraisal Tool to assess the methodological quality of studies. We used the Persuasive System Design (PSD) model as a framework for data extraction and analysis to examine how Internet-based CBT and IPT, as technology-based systems, influence the attitudes and behaviors of system users. PSD components described for the therapies were linked to reported outcomes using a cross-case comparison method and thematic synthesis. Results We identified 19

    Full Text Available The purpose of this study was to explore the question: Is a service member’s post-deployment marital satisfaction correlated with frequency and mode of communication during deployment? This study used an anonymous exploratory design with a sample of 119 Operation Iraqi Freedom (OIF or Operation Enduring Freedom (OEF married veterans. Service members who communicated daily during deployment with their spouses had higher marital satisfaction scores than those who communicated less than once per week. Additionally, participants who used US mail had the highest marital satisfaction scores compared to telephone and internet-based communication. This study expands the overwhelmingly qualitative current literature to include quantitative analysis of this topic. This study also depicts the veterans’ experiences since many of the previous studies of this topic used samples of spouses.

Today, otologists have a wide array of tools from which to choose, but may find it difficult to know which middle ear implant works best.   Materials and Methods: A prospective study of 80 patients who underwent ossiculoplasty was performed in the ear, nose, and throat (ENT department at a tertiary health care facility from 2011 to 2013. Patients with chronic suppurative otitis media with an air-bone gap (ABG of >25 dB with ossicular involvement were included in the study. Total ossicular replacement prosthesis (TORP, partial ossicular replacement prosthesis (PORP, and refashioned incus were used. Success was defined as ABG   Results: The majority patients were of middle age with moderate conductive hearing loss. Incus was the most susceptible ossicle. Overall success rate in this study was 80.0% with an average change of 15.76 dB in ABG.   Conclusion:  With continuing advances in our understanding of middle ear mechanics, the results of ossiculoplasty are improving and results can be very rewarding in experienced hands. Severity of preoperative ear discharge, preoperative mastoid cellularity, presence of disease, and surgical procedure proved to be significant prognostic factors. Autograft incus and PORP fared better when the malleus handle was present while TORP gave better results when the malleus handle was eroded.

    Context 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. Evidence Acquisition 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. Evidence Synthesis 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. Conclusion 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.

    Objectives To determine the proportion of diabetic patients who develop adverse glycaemic events when fasting regularly. Design Prospective observational study conducted at a tertiary care hospital in South Asia. Five hundred and twenty-three patients were assessed for eligibility, and 150 were included in the final analysis. Diabetic patients over 18 years of age who were willing to fast regularly and make a chart of their daily blood sugar levels were included in the study. The main outcome measures were hypoglycaemic and hyperglycaemic events. Frequencies and percentages were calculated for quantitative variables, while mean±SD were documented for qualitative variables. Relative risk was calculated as a measure of association. Results Of a total of 150 individuals, 10% experienced hypoglycaemia, while 3.3% reported hyperglycaemic episodes. Only 8.7% of the participants discontinued one or more fasts; however, none of them required hospitalisation. There is a negative association between a visit to a physician by diabetic patients before they begin to fast regularly and the risk of developing hypoglycaemia (relative risk 0.73). Conclusions Many diabetic patients who fast regularly are at high risk of adverse glycaemic events. Most diabetics do not consult their physicians before fasting to adjust medications and lifestyle. Various strategies should be planned and implemented for the awareness and education of such patients to avoid adverse glycaemic events and subsequent complications. PMID:28588932

    We conducted a one-year prospective study involving a prehospital Emergency Medical Service in the Netherlands to investigate the incidence of failed or difficult prehospital endotracheal intubation. During the study period the paramedics were asked to fill in a registration questionnaire after every endotracheal intubation. Of the 26,271 patient contacts, 256 endotracheal intubations were performed by paramedics in one year. Endotracheal intubation failed in 12 patients (4.8%). In 12.0% of 249 patients, a Cormack and Lehane grade III laryngoscopy was reported and a grade IV laryngoscopy was reported in 10.4%. The average number of endotracheal intubations per paramedic in one year was 4.2 and varied from zero to a maximum of 12. The median time between arrival on the scene and a positive capnograph was 7 min.38 s in the case of a Cormack and Lehane grade I laryngoscopy and 14 min.58 s in the case of a Cormack and Lehane grade 4 laryngoscopy. The incidence of endotracheal intubations performed by Dutch paramedics in one year was low, but endotracheal intubation was successful in 95.2%, which is comparable with findings in international literature. Early capnography should be used consistently in prehospital airway management.

    Monomelic neurogenic syndromes are rare. Their classification and prognostic features have not been addressed in the European population. A prospective study of 17 patients with monomelic neurogenic amyotrophy, of upper or lower limb onset, with progression limited to one limb for three or more years. Clinical and neurophysiological studies were performed in the subsequent 3 or more years. Fifteen patients were of European origin and two were Asian. Those presenting with proximal monomelic weakness or with involvement of the posterior compartment of the lower leg showed no further progression after the initial period of development of the syndrome. Brisk reflexes in wasted muscles did not predict progression. Electromyographic signs of denervation in the opposite limb at presentation did not predict later progression. Transcranial magnetic stimulation (TMS) features of corticospinal dysfunction were a useful predictor of subsequent progression (p=0.01). One patient with lower limb onset developed conduction block with weakness in an upper limb nine years after presentation, and this upper limb weakness responded to IVIg therapy. This adult-onset European group of patients is different as compared with juvenile-onset Asian cases. The clinical syndromes appear heterogeneous, but neurophysiological investigations, in particular TMS, can be helpful in determining prognosis. Multifocal motor neuropathy should be considered when there is progression, even years after onset.

    Full Text Available Background: Africa has very few neurosurgeons. These are almost exclusively in urban centers. Consequently, people in rural areas, most of the African population, have poor or no access to neurosurgical care. We have recently pioneered rural neurosurgery in Nigeria. Objectives: This report details our initial experiences and the profile of neurosurgical admissions in our center. Methods: A prospective observational study of all neurosurgical patients managed at a rural tertiary health institution in Nigeria from December 2010 to May 2012 was done. Simple descriptive data analysis was performed. Results: A total of 249 males (75.2% and 82 females (24.8% were managed. The median age was 37 years (range: Day of birth – 94 years. Trauma was the leading cause of presentation with 225 (68.0% and 35 (10.6% having sustained head and spinal injuries, respectively. Operative intervention was performed in 54 (16.3%. Twenty-four (7.2% patients discharged against medical advice, mostly for economic reasons. Most patients (208, 63.4% had satisfactory outcome while 30 (9.1% died. Conclusion: Trauma is the leading cause of rural neurosurgical presentations. There is an urgent need to improve access to adequate neurosurgical care in the rural communities.

    A prospective study of pedalcycle accident morbidity and mortality was carried out from February to mid-November 1983 because of the high frequency of child cyclist injuries that were occurring on the relatively flat Redcliffe Peninsula. These injuries were apparently associated with the large number of young children who use a bicycle as their main mode of transport to and from school. The schools were surveyed for the extent of bicycle use and cyclists were surveyed for the amount of protective clothing that was worn while involved in cycling. It was found that a disturbingly large number of young children made regular bicycle trips on public roads with the minimal use of safety helmets or any other form of protective clothing. Nearly 40% of on-road accidents involved children of less than 12 years of age, and over 10% of these involved children of six years of age or less. No child in our series of on-road accidents was, at the time of injury, wearing a safety helmet or any other form of protective clothing. No bicycle accidents occurred on the exclusive cycle track of approximately 1 km in length on the Peninsula.

    Although Internet-based surveys are becoming more common, little is known about agreement between administrative claims data and Internet-based survey self- and proxy-reported health care resource utilization (HCRU) data. This analysis evaluated the level of agreement between self- and proxy-reported HCRU data, as recorded through an Internet-based survey, and administrative claims-based HCRU data. The Child and Household Influenza-Illness and Employee Function study collected self- and proxy-reported HCRU data monthly between November 2007 and May 2008. Data included the occurrence and number of visits to hospitals, emergency departments, urgent care centers, and outpatient offices for a respondent's and his or her household members' care. Administrative claims data from the MarketScan® Databases were assessed during the same time and evaluated relative to survey-based metrics. Only data for individuals with employer-sponsored health care coverage linkable to claims were included. The Kappa (κ) statistic was used to evaluate visit concordance, and the intraclass correlation coefficient was used to describe frequency consistency. Agreement for presence of a health care visit and the number of visits were similar for self- and proxy-reported HCRU data. There was moderate to substantial agreement related to health care visit occurrence between survey-based and claims-based HCRU data for inpatient, emergency department, and office visits (κ: 0.47-0.77). There was less agreement on health care visit frequencies, with intraclass correlation coefficient values ranging from 0.14 to 0.71. This study's agreement values suggest that Internet-based surveys are an effective method to collect self- and proxy-reported HCRU data. These results should increase confidence in the use of the Internet for evaluating disease burden. Copyright © 2012 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

    The aim of the study was to investigate the feasibility and preliminary efficacy of an Internet-based guided self-help intervention for posttraumatic stress symptoms (PTSS) and related symptoms in parents of children on cancer treatment. Parents of children on cancer treatment, who fulfilled the modified symptom criteria on the PTSD Checklist, were randomly allocated to the intervention or to a wait-list control condition. The intervention group accessed a 10-week guided self-help program via the Internet based on principles from cognitve behavior therapy. The primary outcome PTSS and the secondary outcomes depression and anxiety were assessed by self-report preintervention and postintervention. Seven hundred forty-seven parents were approached and informed about the study, 92 were assessed for eligibility, and 58 were included and randomized to the intervention (n = 31) or wait list (n = 27). Eightteen participants completed the intervention. Intention-to-treat analyses indicated a significant effect of the intervention on PTSS with a large between-group effect size at postassessment (Cohen's d = 0.88). The intervention group reported reductions in PTSS with a large within-group effect size (d = 1.62) compared with a minimal reduction in the wait-list group (d = 0.09). There was a significant intervention effect on depression and anxiety and reductions in the intervention group with large within-group effect sizes (d = 0.85-1.09). Findings indicate a low enrollment rate and considerable attrition but also that Internet-based guided self-help shows promise for parents of children on cancer treatment who report a high level of PTSS and would like to take part in an Internet-based intervention. © 2015 The Authors.

    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.

Aims: Study on quality of newborn care in rural areas.  Settings and Design: This is a prospective study in the field practice areas of J.N. Medical College and areas under primary health centre of public health care system in Wardha district.  Methods and Material: Modified quality check list on the basis of PHC MAP module guidelines for assessing the quality of service-module 6-user’s guide was prepared. Face to face interview with 205 (group-A/104 nos + group-B/101 nos mother of newborn was method to collected information in three postnatal visits.  Statistical analysis: Quality (verbal response of each service was quantified as acceptable, average and worst.  Quality of both the groups was compared by calculating P-value after utilizing Z-test.  Results: Over all acceptable quality of medical history was 30.03%, physical examination was 21.73%, preventive service was 91.17% and counseling was 24.83%. Significant difference between two groups were found on history taking for (cry, breathing and body movement of baby, recording weight and counseling regarding exclusive breast feeding for first 6 month of life. Worst quality in this study were observed in history for anything applying to eyes, umbilical cord stump and complication of baby for which appropriate management was taken. Except for weight recording and examination of head and fontanels all other variables under physical examination were not acceptable. Counseling regarding high risk condition of baby was only 13.66%. Conclusion: Existing newborn services except immunization is inadequate and needs to be strengthened especially physical examination and counseling services.

    Full Text Available Internet-based problem-solving training (IPST effectively reduces depressive symptoms in employees. Yet, it is unknown which employees benefit most from this particular treatment. The study aimed to identify predictors and moderators of treatment outcome in IPST offered to employees with depressive symptoms. Within a randomized controlled trial (N = 150, designed to test the effectiveness of IPST, variables that predict and moderate the effects of IPST when compared with a waitlist control group (WLC were explored. The outcome was change in depression severity, assessed using the Center for Epidemiological Studies Depression Scale (CES-D. Both depression severity and other psychopathological symptoms and potential predictors/moderators were assessed as self-reports at baseline (t1 and in follow-up assessments after seven weeks (t2, three months (t3 and six months (t4. Higher depression severity at baseline predicted improvement in depressive symptomology in follow-up assessments after seven weeks, and three- and six months. Depression severity moderated the effectiveness of IPST assessed at six-month follow-up. Simple slope analyses revealed that the long-term effectiveness of the intervention was more pronounced among participants with high (CES-D range: 33–44, M = 37.0, SD = 3.2 and moderate (CES-D range: 14–32, M = 23.1, SD = 5.6 depression baseline scores, compared to participants displaying low depression baseline scores (CES-D range: 5–13, M = 9.0, SD = 2.2. No indication was found that participants presenting low depression severity at baseline significantly benefitted from IPST in the long-term. IPST might be appropriate for employees with a wide range of different characteristics. While there appears to be no reason to exclude employees with severe depression from Internet-based occupational mental health interventions, for employees low in depression severity, watchful waiting or potentially no intervention should

    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.

    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.

    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.

  1. Personality change following internet-based cognitive behavior therapy for severe health anxiety.

    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.

    Most approaches to the detection of presymptomatic or prodromal Alzheimer's disease require the costly collection and analysis of biological samples or neuroimaging measurements. The Dementia Risk Assessment (DRA) was developed to facilitate this detection by collecting self-report and proxy-report of dementia risk variables and episodic memory performance on a free Internet website. We now report two validation studies. In Study 1, 130 community-residing older adults seeking memory screening at senior health fairs were tested using the Mini-Cog, and were then observed while taking the DRA. They were compared to a demographically-matched subsample from our anonymous Internet sample. Participants seeking memory screening had more dementia risk factors and obtained lower scores on the DRA's recognition memory test (RMT) than their Internet controls. In addition, those who failed the Mini-Cog obtained much lower scores on the RMT than those who passed the Mini-Cog. In Study 2, 160 older adults seeking evaluation of cognitive difficulties took the DRA prior to diagnostic evaluations at outpatient dementia clinics. Patients who ultimately received the diagnosis of a dementia syndrome scored significantly lower on the RMT than those diagnosed with other conditions or deemed normal. Lower education, family history of dementia, presence of hypercholesterolemia and diabetes, and memory test score distinguished the dementia and no-dementia groups with around 82% accuracy. In addition, score on the RMT correlated highly with scores on other instruments widely used to detect cognitive decline. These findings support the concurrent validity of the DRA for detecting prevalent cognitive impairment. Prospective studies of cognitively normal persons who subsequently develop dementia will be necessary to establish its predictive validity.

    In the 20th century, catatonia was usually deemed a subtype of schizophrenia. Recently, the nature and classification of catatonia are being reconsidered. This study is the first to describe catatonia using prospectively collected data and to examine how catatonic schizophrenia differs from, or resembles, other types of schizophrenia. Data were analyzed in a cohort of 90,079 offspring followed from birth till ages 29-41 years. Proportional hazards models were used, calculating time to first psychiatric hospital admission, to compare risk factors for catatonic schizophrenia vs "other schizophrenia." Of 568 cases of schizophrenia, 43 (7.6%) had catatonic schizophrenia. The sexes were equally at risk for catatonic schizophrenia in contrast to other schizophrenia, for which the incidence was higher in males (1.70, 1.42-2.03, P catatonic schizophrenia in contrast to other schizophrenia, in which the risk to offspring of fathers age 35+ was 1.27 (1.03-1.57, P = .03) compared with those of younger fathers. Those with catatonic schizophrenia were somewhat more likely to have older mothers (aged 35+) (relative risk = 2.14, 0.85-5.54) while maternal age was not related to other schizophrenia. Both were equally affected by parental history of schizophrenia. Patients with catatonia were significantly more likely to attempt suicide (P = .006). Patients with catatonic schizophrenia show a somewhat different profile of risk factors from those with other types of schizophrenia in this cohort and are more likely to attempt suicide. This lends some support to the hypothesis that catatonic schizophrenia may have a distinct etiology.

    The Great East Japan Earthquake occurred on March 11, 2011. Tokyo and Osaka, which are located 375 km and 750 km, respectively, from the epicenter, experienced tremors of 5.0 lower and 3.0 seismic intensity on the Japan Meteorological Agency scale. The Great East Japan Earthquake was the fourth largest earthquake in the world and was accompanied by a radioactive leak at a nuclear power plant and a tsunami. In the aftermath of a disaster, some affected individuals presented to mental health facilities with acute stress disorder (ASD) and/or post-traumatic stress disorder (PTSD). However, few studies have addressed mental stress problems other than ASD or PTSD among the general public immediately after a disaster. Further, the effects of such a disaster on residents living at considerable distances from the most severely affected area have not been examined. This study aimed to prospectively analyze the effect of a major earthquake on the prevalence of insomnia among residents of Tokyo and Osaka. A prospective online questionnaire study was conducted in Tokyo and Osaka from January 20 to April 30, 2011. An Internet-based questionnaire, intended to be completed daily for a period of 101 days, was used to collect the data. All of the study participants lived in Tokyo or Osaka and were Consumers' Co-operative Union (CO-OP) members who used an Internet-based food-ordering system. The presence or absence of insomnia was determined before and after the earthquake. These data were compared after stratification for the region and participants' age. Multivariate analyses were conducted using logistic regression and a generalized estimating equation. This study was conducted with the assistance of the Japanese CO-OP. The prevalence of insomnia among adults and minors in Tokyo and adults in Osaka increased significantly after the earthquake. No such increase was observed among minors in Osaka. The overall adjusted odds ratios for the risk of insomnia post-earthquake versus pre

    Mindfulness-based interventions have proven effective for the transdiagnostic treatment of heterogeneous anxiety disorders. So far, no study has investigated the potential of mindfulness-based treatments when delivered remotely via the Internet. The current trial aims at evaluating the efficacy of a stand-alone, unguided, Internet-based mindfulness treatment program for anxiety. Ninety-one participants diagnosed with social anxiety disorder, generalized anxiety disorder, panic disorder, or anxiety disorder not otherwise specified were randomly assigned to a mindfulness treatment group (MTG) or to an online discussion forum control group (CG). Mindfulness treatment consisted of 96 audio files with instructions for various mindfulness meditation exercises. Primary and secondary outcome measures were assessed at pre-, posttreatment, and at 6-months follow-up. Participants of the MTG showed a larger decrease of symptoms of anxiety, depression, and insomnia from pre- to postassessment than participants of the CG (Cohen's d(between)=0.36-0.99). Within effect sizes were large in the MTG (d=0.82-1.58) and small to moderate in the CG (d=0.45-0.76). In contrast to participants of the CG, participants of the MTG also achieved a moderate improvement in their quality of life. The study provided encouraging results for an Internet-based mindfulness protocol in the treatment of primary anxiety disorders. Future replications of these results will show whether Web-based mindfulness meditation can constitute a valid alternative to existing, evidence-based cognitive-behavioural Internet treatments.

    Hearing impairment is most accurately measured by a clinical pure-tone audiogram. This method is not suitable for large-scale, population-based epidemiological studies as it requires that study participants visit a clinic with trained personnel. An alternative approach to measuring hearing ability is self-estimation through questionnaires, but the correlation to clinical audiometric tests varies. To evaluate an Internet-based hearing test pilot compared to a question about self-estimated hearing and the feasibility of using an Internet-based hearing test and an Internet-based questionnaire in a population of 560 members of the Swedish Hunters' Association in the age group 20-60 years. An invitation was mailed to the participants in March 2007 together with the URL to the study Web site, a personal username, and a password. The Web site included the questionnaire, the hearing test, and instructions for participating in the study. The hearing test resembles a clinical audiogram presenting 6 tones between 500 and 8000 Hz. Tones are presented between 0 and 60 dB, and the participant responds to the tones by pressing the space bar. The hearing test requires headphones and is based on JAVA programming. Before the participant can start the hearing test, it has to be calibrated against a reference person with good hearing between 15 and 35 years of age. After 5 months, 162 out of 560 (29%) had answered the questionnaire, out of which 88 (16%) had completed the hearing test. Those who actively declined participation numbered 230 out of 560 (41%). After removing duplicates and hearing tests calibrated by unreliable reference data, 61 hearing tests remained for analysis. The prevalence of hearing impairment from the Internet-based hearing test was 20% (12 out of 61), compared to 52% (32 out of 61) from the self-estimated question. Those who completed the hearing test were older than the non-participants, and more had headphones (P = .003) and the correct version of the JAVA

    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 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.

    The cardiovascular disease (CVD) is the leading cause of disability and premature death around the world. The ongoing publication of systematic and critical literature reviews has contributed to generate a kaleidoscope of guidelines by different scientific organizations. We investigated the accordance among the most popular web-based CVD risk calculators on the Internet. We carried out a simple study, by estimating the risk of CVD using the most popular Internet-based calculators available on the Internet. A Google search was performed, using the keyword "cardiovascular risk calculator", to identify the first 10 websites providing free on-line CVD risk calculators. We arbitrarily selected the cardiovascular profile of two subjects of a typical Western family: a 55-year man at a likely intermediate cardiovascular risk and a 45-year woman at a probable low risk. The score calculated according to the two arbitrary CVD risk profiles, one of whom was supposed to be at intermediate risk and the other at lower risk, was extremely variable. More specifically, the 10-year CVD risk of the 55-year old man varied from 3% to over 25% (median value, 12.9%, interquartile range [IQR], 10.7-19.0%), whereas that of the 45-year women varied between 0% and 4% (median value, 1.2%; IQR, 0.4-2.2%), thus displaying a nearly 10-fold variation in both cases. We concluded from our analysis of 11 different Internet-based CVD risk calculators that the final 10-year risk score can be extremely different, especially for the 55-year old man at predictably intermediate risk.

    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 (puse 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.

    The study aim was to evaluate the long-term efficacy of Internet-based cognitive behavioral therapy (CBT) for sexual dysfunctions in 84 breast cancer survivors. The positive effects of the intervention on overall sexual functioning, sexual desire, sexual arousal, vaginal lubrication, discomfort during sex, sexual distress, and body image observed immediately posttreatment were maintained at three- and nine-month follow-ups. Although sexual pleasure decreased during follow-up, it did not return to baseline levels. Our findings provide evidence that Internet-based CBT has a sustained, positive effect on sexual functioning and body image of breast cancer survivors with a sexual dysfunction.

    Full Text Available Abstract Background The clinical effectiveness of complementary and alternative medicines (CAMs is widely debated because of a lack of clinical trials. The internet may provide an effective and economical approach for undertaking randomised controlled trials (RCTs of low-risk interventions. We investigated whether the internet could be used to perform an internet-based RCT of a CAM fulfilling the revised CONSORT (Consolidated Standards of Reporting Trials statement quality checklist for reporting of RCTs. A secondary aim was to examine the effect of probiotics compared to placebo in terms of well-being over 12 weeks. Methods People aged ≥18 years with confirmed spondyloarthropathy living in the United Kingdom with internet access were invited to participate in an internet-based RCT of probiotic compared to placebo for improving well-being and bowel symptoms. The intervention was a probiotic containing 4 strains of live bacteria or identical placebo taken by mouth daily for 3 months. The primary outcome measure was the performance of the trial according to the revised CONSORT statement. Results 147 people were randomised into the trial. The internet-based trial of the CAM fulfilled the revised CONSORT statement such as efficient blinding, allocation concealment, intention to treat analysis and flow of participants through the trial. Recruitment of the required number of participants was completed in 19 months. Sixty-five percent (96/147 completed the entire 3 months of the trial. The trial was low cost and demonstrated that in an intention to treat analysis, probiotics did not improve well-being or bowel symptoms. Conclusion The internet-based RCT proved to be a successful and economical method for examining this CAM intervention. Recruitment, adherence and completion rate were all similar to those reported with conventional RCTs but at a fraction of the cost. Internet-based RCTs can fulfil all the criteria of the revised CONSORT statement and

    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, Padvertising and branding (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

    The aim of this paper is to advance rigorous Internet-based HIV/STD Prevention quantitative research by providing guidance to fellow researchers, faculty supervising graduates, human subjects' committees, and review groups about some of the most common and challenging questions about Internet-based HIV prevention quantitative research. The authors represent several research groups who have gained experience conducting some of the first Internet-based HIV/STD prevention quantitative surveys in the US and elsewhere. Sixteen questions specific to Internet-based HIV prevention survey research are identified. To aid rigorous development and review of applications, these questions are organized around six common criteria used in federal review groups in the US: significance, innovation, approach (broken down further by research design, formative development, procedures, sampling considerations, and data collection); investigator, environment and human subjects' issues. Strategies promoting minority participant recruitment, minimizing attrition, validating participants, and compensating participants are discussed. Throughout, the implications on budget and realistic timetabling are identified.

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.

    Full Text Available Abstract Background Despite the health benefits of regular physical activity, most children are insufficiently active. Schools are ideally placed to promote physical activity; however, many do not provide children with sufficient in-school activity or ensure they have the skills and motivation to be active beyond the school setting. The aim of this project is to modify, scale up and evaluate the effectiveness of an intervention previously shown to be efficacious in improving children’s physical activity, fundamental movement skills and cardiorespiratory fitness. The ‘Internet-based Professional Learning to help teachers support Activity in Youth’ (iPLAY study will focus largely on online delivery to enhance translational capacity. Methods/Design The intervention will be implemented at school and teacher levels, and will include six components: (i quality physical education and school sport, (ii classroom movement breaks, (iii physically active homework, (iv active playgrounds, (v community physical activity links and (vi parent/caregiver engagement. Experienced physical education teachers will deliver professional learning workshops and follow-up, individualized mentoring to primary teachers (i.e., Kindergarten – Year 6. These activities will be supported by online learning and resources. Teachers will then deliver the iPLAY intervention components in their schools. We will evaluate iPLAY in two complementary studies in primary schools across New South Wales (NSW, Australia. A cluster randomized controlled trial (RCT, involving a representative sample of 20 schools within NSW (1:1 allocation at the school level to intervention and attention control conditions, will assess effectiveness and cost-effectiveness at 12 and 24 months. Students’ cardiorespiratory fitness will be the primary outcome in this trial. Key secondary outcomes will include students’ moderate-to-vigorous physical activity (via accelerometers, fundamental movement

    Social anxiety disorder (SAD) is highly prevalent and associated with a substantial societal economic burden, primarily due to high costs of productivity loss. Cognitive behavior group therapy (CBGT) is an effective treatment for SAD and the most established in clinical practice. Internet-based cognitive behavior therapy (ICBT) has demonstrated efficacy in several trials in recent years. No study has however investigated the cost-effectiveness of ICBT compared to CBGT from a societal perspective, i.e. an analysis where both direct and indirect costs are included. The aim of the present study was to investigate the cost-effectiveness of ICBT compared to CBGT from a societal perspective using a prospective design. We conducted a randomized controlled trial where participants with SAD were randomized to ICBT (n=64) or CBGT (n=62). Economic data were assessed at pre-treatment, immediately following treatment and six months after treatment. Results showed that the gross total costs were significantly reduced at six-month follow-up, compared to pre-treatment in both treatment conditions. As both treatments were equivalent in reducing social anxiety and gross total costs, ICBT was more cost-effective due to lower intervention costs. We conclude that ICBT can be more cost-effective than CBGT in the treatment of SAD and that both treatments reduce societal costs for SAD. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background Binge eating disorder (BED is a prevalent clinical eating disorder associated with increased psychopathology, psychiatric comorbidity, overweight and obesity, and increased health care costs. Since its inclusion in the DSM-IV, a few randomized controlled trials (RCTs have suggested efficacy of book-based self-help interventions in the treatment of this disorder. However, evidence from larger RCTs is needed. Delivery of self-help through new technologies such as the internet should be investigated in particular, as these approaches have the potential to be more interactive and thus more attractive to patients than book-based approaches. This study will evaluate the efficacy of an internet-based guided self-help program (GSH-I and cognitive-behavioral therapy (CBT, which has been proven in several studies to be the gold standard treatment for BED, in a prospective multicenter randomized trial. Methods The study assumes the noninferiority of GSH-I compared to CBT. Both treatments lasted 4 months, and maintenance of outcome will be assessed 6 and 18 months after the end of treatment. A total of 175 patients with BED and a body mass index between 27 and 40 kg/m2 were randomized at 7 centers in Germany and Switzerland. A 20% attrition rate was assumed. As in most BED treatment trials, the difference in the number of binge eating days over the past 28 days is the primary outcome variable. Secondary outcome measures include the specific eating disorder psychopathology, general psychopathology, body weight, quality of life, and self-esteem. Predictors and moderators of treatment outcome will be determined, and the cost-effectiveness of both treatment conditions will be evaluated. Results The methodology for the INTERBED study has been detailed. Conclusions Although there is evidence that CBT is the first-line treatment for BED, it is not widely available.

    Purpose Internet-based treatments have been tested for several psychological disorders. However, few studies have directly assessed the acceptability of these self-applied interventions in terms of expectations, satisfaction, treatment preferences, and usability. Moreover, no studies provide this type of data on Internet-based treatment for flying phobia (FP), with or without therapist guidance. The aim of this study was to analyze the acceptability of an Internet-based treatment for FP (NO-FEAR Airlines) that includes exposure scenarios composed of images and real sounds. A secondary aim was to compare patients’ acceptance of two ways of delivering this treatment (with or without therapist guidance). Patients and methods The sample included 46 participants from a randomized controlled trial who had received the self-applied intervention with (n = 23) or without (n = 23) therapist guidance. All participants completed an assessment protocol conducted online and by telephone at both pre- and posttreatment. Results Results showed good expectations, satisfaction, opinion, and usability, regardless of the presence of therapist guidance, including low aversiveness levels from before to after the intervention. However, participants generally preferred the therapist-supported condition. Conclusion NO-FEAR Airlines is a well-accepted Internet-based treatment that can help enhance the application of the exposure technique, improving patient acceptance and access to FP treatment.

    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

    Full Text Available PURPOSE: The Internet expands the range and flexibility of teaching options and enhances the ability to process the ever-increasing volume of medical knowledge. The aim of this study is to describe and discuss our experience with transforming a traditional medical training course into an Internet-based course. METHOD: Sixty-nine students were enrolled for a one-month course. They answered pre- and post-course questionnaires and took a multiple-choice test to evaluate the acquired knowledge. RESULTS: Students reported that the primary value for them of this Internet-based course was that they could choose the time of their class attendance (67%. The vast majority (94% had a private computer and were used to visiting the Internet (75% before the course. During the course, visits were mainly during the weekends (35% and on the last week before the test (29%. Thirty-one percent reported that they could learn by reading only from the computer screen, without the necessity of printed material. Students were satisfied with this teaching method as evidenced by the 89% who reported enjoying the experience and the 88% who said they would enroll for another course via the Internet. The most positive aspect was freedom of scheduling, and the most negative was the lack of personal contact with the teacher. From the 80 multiple-choice questions, the mean of correct answers was 45.5, and of incorrect, 34.5. CONCLUSIONS: This study demonstrates that students can successfully learn with distance learning. It provides useful information for developing other Internet-based courses. The importance of this new tool for education in a large country like Brazil seems clear.

    Within recent years, public health interventions have become technology 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 (EBIs). The US National HIV/AIDS Strategy states that people living with HIV should have access to EBIs such as 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 and disadvantages of home or CBO 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.

    Full Text Available Abstract Background The internet is becoming a widely used source of accessing medical research through various on-line databases. This instant access to information is of benefit to busy clinicians and service users around the world. The population of the Arab World is comparable to that of the United States, yet it is widely believed to have a greatly contrasting output of randomised controlled trials related to mental health. This study was designed to investigate the existence of such research in the Arab World and also to investigate the availability of this research on-line. Methods Survey of findings from three internet-based potential sources of randomised trials originating from the Arab world and relevant to mental health care. Results A manual search of an Arabic online current contents service identified 3 studies, MEDLINE, EMBASE, and PsycINFO searches identified only 1 study, and a manual search of a specifically indexed, study-based mental health database, PsiTri, revealed 27 trials. Conclusion There genuinely seem to be few trials from the Arab world and accessing these on-line was problematic. Replication of some studies that guide psychiatric/psychological practice in the Arab world would seem prudent.

    To test the effectiveness of an Internet-based education programme about venous leg ulcer nursing care on perceived and theoretical knowledge levels and attitudes among nurses working in home health care. Nurses have been shown to have knowledge gaps in venous leg ulcer nursing care. Internet-based learning could offer a means for flexible continuing education for home healthcare environment. Quasi-experimental study with pre- and postmeasurements and nonequivalent intervention and comparison groups. Nurses (n = 946) in home health care in two Finnish municipalities were invited to participate in the study and divided into intervention and comparison groups. The intervention group received education programme about venous leg ulcer nursing care, while the comparison group did not. Data were collected at baseline, at six weeks and at 10 weeks to test the hypotheses: nurses using education programme about venous leg ulcer nursing care will have higher level of knowledge and more positive attitudes than those not using education programme about venous leg ulcer nursing care. An analysis of variance and mixed models with repeated measures were used to test differences in knowledge and attitudes between and within the groups. There were statistically significant increases in knowledge levels in the intervention group from baseline to the first and second follow-up measurements. In the comparison group, the knowledge levels remained unchanged during the study. Attitude levels remained unchanged in both groups. Nurses' perceived and theoretical knowledge levels of venous leg ulcer nursing care can be increased with Internet-based education. However, this increase in knowledge levels is short-lived, which emphasises the need for continuous education. Internet-based education about venous leg ulcer nursing care is recommended for home healthcare nurses. Education programme about venous leg ulcer nursing care provides flexible method for nurses' learning with feasible

    Internet-delivered self-help with minimal therapist guidance has shown promising results for a number of diagnoses. Most of the evidence comes from studies evaluating standardized disorder-specific treatments. A recent development in the field includes transdiagnostic and tailored Internet-based treatments that address comorbid symptoms and a broader range of patients. This study evaluated an Internet-based tailored guided self-help treatment, which targeted symptoms of social anxiety disorder, panic disorder with or without agoraphobia, and generalized anxiety disorder. The tailored treatment was compared both with standardized disorder-specific Internet-based treatment and with a wait-list control group. Both active treatment conditions were based on cognitive-behavioral therapy and lasted for 8 weeks. A total of 132 individuals meeting diagnostic criteria for at least one of the anxiety disorders were randomly assigned to 1 of the 3 conditions. Both treatment groups showed significant symptom reductions as compared with the wait-list control group on primary disorder-unspecific measures of anxiety, depression, and general symptomatology and on secondary anxiety disorder-specific measures. Based on the intention-to-treat sample, mean between-group effect sizes were d = 0.80 for the tailored treatment and d = 0.82 for the standardized treatment, versus wait-list controls. Treatment gains were maintained at 6-month follow-up. No differences were found between the 2 active treatment conditions on any of the measures, including a telephone-administered diagnostic interview conducted at posttreatment. The findings suggest that both Internet-based tailored guided self-help treatments and Internet-based standardized treatments are promising treatment options for several anxiety disorders.

    2013-03-01

    This study aims to assess potential risk factors for Chlamydia trachomatis infection among users of an Internet-based testing service in Sweden. Users of an Internet-based C. trachomatis testing service sent in home urine samples by post which were analysed for C. trachomatis and answered a questionnaire regarding their socio-demographic background, sexual risk behaviour, and sexual health. Potential risk factors for C. trachomatis were determined by logistic regression models. The questionnaire response rate was 86% (6025/6978) with a male and female response rate of 77% and 93%, respectively. 5763 subjects both answered questionnaire and supplied urine sample. Mean age was 24.4 years (range 15-67 years) and 62% were women. The participants'C. trachomatis prevalence in men was 8.0% (73/2163) and 5.6% in women (201/3600). Compared to non-infected individuals, the C. trachomatis infected men and women were younger, had a higher number of sexual partners, more intercourse without condom (only men). After adjusting for age, civil status, and geographical region, the risk factors significantly associated with C. trachomatis infection were multiple partners during the previous year, non-condom usage, and having symptoms (only men). A novel finding was that, in women, believing to be infected and having been requested to be tested by a sexual partner, was associated with an increased risk of having a C. trachomatis infection. The Internet-based C. trachomatis testing service reaches a risk group of men and women. The results emphasise the value of self-risk assessment for C. trachomatis infection and the importance of easy accessible and simple sexual transmitted infection testing services.

    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.

    Investigating the impact of climate change on human health requires the development of efficient tools that link patient symptoms with changing environmental variables. We developed an internet-based hay fever diary linked to simultaneously recorded pollen load and weather variables in Canberra, Australia over spring 2010. We recruited 42 hay fever sufferers to complete a simple online pollen diary daily over a period of 60 days. In conjunction, daily airborne pollen load was counted and meteorological data collected simultaneously. We focused on the relationships between temperature, rainfall, pollen count and rhinoconjunctivitis symptoms. Pollen load increased after a peak rainfall event until the end of the study. Compliance was high, averaging 79% of days per person. Nasal rhinoconjunctivitis symptoms increased in concert with increasing pollen load, and then remained high. Mucosal itching increased more gradually and strongly coincided with increased daily maximum temperature. Our study successfully demonstrated the feasibility of linking pollen load and climate variables to symptoms of rhinoconjunctivitis in the Australian community. However, a larger study would better explore the nature of associations between these variables. Similar online methods could be used to monitor a range of health responses to our changing environment.

    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

    Despite pharmacological treatment of bipolar affective disorder has many advantages; only drug treatment remains insufficiently beneficial to many patients. The combination of pharmacotherapy and internet psychoeducation seems to be the effective way how to improve remission. Internet-based therapy programs offer an exclusive chance for large underserved parts of the population to make evidence-based treatment without the need of full-time therapist. Our goal was to create a psychoeducational program for patients suffering from bipolar disorder that can be used in Czech Republic. There were identified studies through Web of Science, PUBMED, and Scopus databases as well as existing reviews were used in development of comprehensive internet psychoeducational program for patients with bipolar disorder. The search terms included "bipolar disorder", "psychoeducation", and "internet psychoeducation". The search was performed with no language or time restrictions. The internet psychoeducational program was developed in accordance to the data from the literature review. The aim of the Internet psychoeducational program of the Department of Psychiatry University Hospital in Olomouc is to familiarize patients with the fundamental nature of bipolar affective disorder, the character and principles of pharmacotherapy, the recognition of the warning signs of relapse, inappropriate and stressful stereotypes in communication within families, and finally the practice of social skills. Information from studies can help to prepare comprehensive psychoeducational program for bipolar patients.

    The objective of this study is to develop a phonocardiogram (PCG) acquisition and analysis instrument using virtual instrumentation technology and investigate its Internet-based application. The PCG instrument was developed using a Pentium 200 computer, a data acquisition board, and a two-channel custom designed bio-signal preamplifier. LabVIEW was used to create the instrument's front panels. Spectral and joint time-frequency analyses were implemented into the instrument. This instrument can be used to display the PCG and to analyze the individual heart sound and murmur for the detection of heart valve diseases. Using a test-bed, the PCG data acquisition and analysis were performed remotely over the Internet. Through the main PCG panel, an operator can control the acquisition and analysis of PCG signals. In the remote test, real-time transmission of the PCG signal over the Internet was possible. Remote operators were able to view smoothly scrolling PCG waveforms and could control all the acquisition parameters and perform spectral and time-frequency analyses on the acquired heart sound. This study demonstrated that a LabVIEW-based medical virtual instrument provides a low-cost and flexible solution for data acquisition and analysis of PCG. It also showed that the current Internet supports the transmission of real-time PCG signals. Compared with other telemedicine systems, this application transfers not only the medical data, but also the virtual instrument and its signal processing capability through the Internet.

    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.].

  10. 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.

    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/.

    2017-08-29

    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.

    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.

    Major depressive disorders are common among adolescents and can impact all aspects of their daily life. Traditional therapies, cognitive behavioral therapy (CBT), and interpersonal psychotherapy (IPT) have been delivered face-to-face. However, Internet-based (online) delivery of these therapies is emerging as an option for adolescents. Internet-based CBT and IPT involve therapeutic content, interaction between the user and the system, and different technological features embedded into the online program (eg, multimedia). Studies of Internet-based CBT and IPT for adolescent depression differ on all three aspects, and variable, positive therapy effects have been reported. A better understanding of the treatment conditions that influence therapy outcomes is important to designing and evaluating these novel therapies. Our aim was to examine the technological and program delivery features of Internet-based CBT and IPT for adolescent depression and to document their potential relation to treatment outcomes and program use. We performed a realist synthesis. We started with an extensive search of published and gray literature. We included intervention studies that evaluated Internet-based CBT or IPT for adolescent depression. We included mixed-methods and qualitative studies, theoretical papers, and policy/implementation documents if they included a focus on how Internet-based psychological therapy is proposed to work for adolescents with depression/depressive symptoms. We used the Mixed-Methods Appraisal Tool to assess the methodological quality of studies. We used the Persuasive System Design (PSD) model as a framework for data extraction and analysis to examine how Internet-based CBT and IPT, as technology-based systems, influence the attitudes and behaviors of system users. PSD components described for the therapies were linked to reported outcomes using a cross-case comparison method and thematic synthesis. We identified 19 Internet-based CBT programs in 59 documents

    2012-01-01

    Background This article presents an overview of the concept of social capital, reviews prospective multilevel analytic studies of the association between social capital and health, and discusses intervention strategies that enhance social capital. Methods We conducted a systematic search of published peer-reviewed literature on the PubMed database and categorized studies according to health outcome. Results We identified 13 articles that satisfied the inclusion criteria for the review. In general, both individual social capital and area/workplace social capital had positive effects on health outcomes, regardless of study design, setting, follow-up period, or type of health outcome. Prospective studies that used a multilevel approach were mainly conducted in Western countries. Although we identified some cross-sectional multilevel studies that were conducted in Asian countries, including Japan, no prospective studies have been conducted in Asia. Conclusions Prospective evidence from multilevel analytic studies of the effect of social capital on health is very limited at present. If epidemiologic findings on the association between social capital and health are to be put to practical use, we must gather additional evidence and explore the feasibility of interventions that build social capital as a means of promoting health.

    Mastalgia is an important symptom affecting approximately 70% of women and it disrupts the quality of life especially due to the worry of having cancer. In our study, the type and severity of mastalgia symptom of patients who presented to the outpatient clinic with mastalgia complaint were assessed along with their physical examination findings and radiology results. The purpose of the study is to demonstrate the relationship between mastalgia and malignity when assessed in combination with the risk factors of patients. The age, family history, menopausal status, age at the first childbirth, menarche, presence/absence of hormone replacement therapy, type of mastalgia, comorbidities and examination findings of 104 patients, who presented to the General Surgery outpatient clinic with mastalgia symptom, were recorded and assessed in the light of radiological study results. With respect to the mastalgia types of the patients, 38.5% had cyclic pain, 57.7% non-cyclic pain and 3.8% other types of pain. Mild mastalgia was present in 46.2% of the patients, moderate mastalgia in 24% and severe mastalgia in 29.8% of them. According to the BIRADS category, 48.1% of the patients were identified to have BIRADS 1 mass lesions, 39.4% BIRADS 2, 9.6% BIRADS 3 and 2.9% BIRADS 5 mass lesions. The patients who were identified to have BIRADS 5 mass lesions described non-cyclic and severe pain in the post-menopausal period. They had palpable masses along with the pain symptom. Our study suggests that mastalgia symptom does not per se result in suspicion of malignancy, but physical examination and radiological imaging should also be used as needed for confirmation. Studies with a larger patient population are needed to shed light on the mastalgia epidemiology and its relationship with cancer.

    Intaranont, K

    1997-12-01

    Ergonomics studies in Thailand began in 1967 after Professor Kovit Satavuthi graduated from the University of Birmingham, where he worked with Professor Nigel Corlett. Ergonomics was offered as an elective in the IE curriculum at Chulalongkorn University. Professor Satavuthi was later invited to teach manufacturing process and system at the Department of Occupational Health and Safety, School of Public Health, Mahidol University. He then added the ergonomics concept to the class as part of his lectures. The first international conference was organized by the Central Coordinating Board of SEAMEO-TROPMED Project, and it was held in Bangkok from 19-23 June 1972, thus bringing ergonomics into public attention. Most participants came from medical science and public health fields, however. Ergonomics popularity has begun to gain momentum in the past 4-5 years. This could be the result of more universities paying serious consideration to provide ergonomics knowledge to their students. It is also well-accepted that ergonomics is a multidisciplined subject. It requires knowledge from medical sciences, sociology, psychology, public health, and engineering. The results of ergonomics studies will have greater chances of success if they are concluded from all disciplines of knowledge. This paper reports some previous studies in Thailand and discuss how to build up an ergonomics team and to produce reasonable results with a sound application plan.

    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.

    Increasing home cooking while decreasing the consumption of food prepared away from home is a commonly recommended weight management strategy, however research on where individuals obtain ideas about meals to cook at home is limited. This study examined the characteristics of individuals who reported using traditional and Internet-based resources for meal ideas. 583 participants who were ≥50% responsible for household meal planning were recruited to approximate the 2014 United States Census distribution on sex, age, race/ethnicity, and household income. Participants reported demographic characteristics, home cooking frequency, and their use of 4 traditional resources for meal ideas (e.g., cookbooks), and 7 Internet-based resources for meal ideas (e.g., Pinterest) in an online survey. Independent samples t-tests compared home cooking frequency by resource use. Association rule learning identified those demographic characteristics that were significantly associated with resource use. Family and friends (71%), food community websites (45%), and cookbooks (41%) were the most common resources reported. Cookbook users reported preparing more meals at home per week (M = 9.65, SD = 5.28) compared to non-cookbook users (M = 8.11, SD = 4.93; t = -3.55, p < 0.001). Resource use was generally higher among parents and varied systematically with demographic characteristics. Findings suggest that home cooking interventions may benefit by modifying resources used by their target population. Copyright © 2016 Elsevier Ltd. All rights reserved.

The data on final CPR exam grades, collected both groups trained physicians, were obtained for a total of 80 physicians in 2011. An independent sample t-test analysis indicated that participants in the IBL format reported significantly higher mean ratings for this format (62.5 ±2.32 than TCL format (54.6±2.18 (p=.001. There were no significant differences between the two groups in cognitive gains (p<0.05. well-designed IBL content can be effective or a supplement component to CME.

    Experimental studies of criticality safety are under way using STACY and TRACY in NUCEF. Collection of fundamental data on criticality in a solution system is undergoing with STACY to confirm that the likelihood of criticality safety in the system constructed on the assumption of apparatuses in a reprocessing plant is enough large. Whereas some experiments simulating criticality accidents in a reprocessing plant using TRACY were designed to investigate the behaviors of fuel solution and radioactive matters in order to clarify whether it is possible to safely shut them in the facility even if a critical accident occurs. Both STACY and TRACY reached the criticality in 1995. Up to now a series of criticality experiments have been done using STACY with a core tank φ60 cm and the first periodical examination is now under way. On the other hand, we have a plan using TRACY to investigate the behaviors of nuclear heat solution at a criticality accident, and the releasing, transfer and deposition of radioactive materials. After reaching the criticality for the first, the performance verification test has been conducted. The full-scale study using TRACY is planned to begin in the second half of 1996. (M.N.)

    Managing chronic tinnitus is challenging, and innovative ways to address the resulting health-care burden are required. Internet-based cognitive behavioral therapy (iCBT) for tinnitus shows promise as a cost-effective treatment option. The feasibility and effectiveness of iCBT in the United Kingdom are yet to be explored. Furthermore, it is not known if iCBT can be supported by an audiologist rather than a psychologist. This study aimed to determine the feasibility of guided iCBT using audiological support on tinnitus distress and tinnitus-related comorbidities. Furthermore, it aimed to establish the feasibility of iCBT for tinnitus distress in the United Kingdom, by determining recruitment, attrition, and compliance rates. Finally, it aimed to identify which aspects of the protocol require refinement for subsequent clinical trials. A single-group open trial design was implemented. This study would serve as a prerequisite study, to identify barriers, before undertaking effectiveness trials. Participants consisted of 37 adults (18 males, 19 females), with an age range of between 50 and 59 yr. The mean preintervention tinnitus severity rating was 56.15 (standard deviation = 18.35), which is categorized as "severe tinnitus" as measured by the Tinnitus Functional Index (TFI). Five participants withdrew during the study, and 29 of the remaining participants completed the postintervention questionnaire. The guided iCBT intervention ran over an eight-week period and consisted of 16 obligatory modules and five optional modules. The intervention was designed to be interactive, interesting, and stimulating. A key element was the provision of support from an audiologist throughout the program. Online questionnaires were used throughout the study. These were administered at baseline and postintervention to determine attrition and compliance rates and to facilitate sample size estimates for further clinical trials. Outcome measures for tinnitus severity, hearing handicap

    The purpose of this research was to design and realize a real-time tele-monitoring system with multiphysiological parameters using the Internet. Both the Client/Server (C/S) mode and Peer-to-Peer (P2P) mode were used in the system's network communication. The C/S mode is used to upload, retrieve, and download physiological data. The P2P mode provides realtime tele-monitoring and video chatting between doctors and patients. Experiment results show that P2P technology could efficiently improve the transmission speed of the physiological parameters. This study demonstrates an effective method of remote monitoring of physiological parameters in real time.

    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.

    1996-01-15

    Prospective studies often involve rare events as study outcomes, and a primary concern is to identify risk factors and risk groups associated with the outcomes. We discuss practical solutions to risk factor analyses in prospective studies and address strategies to determine tree structures, to estimate relative risks, and to manage missing data in connection with some important epidemiologic problems. Some of the basic ideas for our strategies follow from work of Breiman, Friedman, Olshen, and Stone, although we propose extensions to their methods to resolve some practical problems that arise in implementation of these methods in epidemiologic studies. To illustrate these ideas, we analyse low birthweight associated risk factors with use of a data set from the Yale Pregnancy Outcome Study.

    2014-01-01

    Information-intensive Web services such as price comparison sites have recently been gaining popularity. However, most users including novice shoppers have difficulty in browsing such sites because of the massive amount of information gathered and the uncertainty surrounding Web environments. Even conventional price comparison sites face various problems, which suggests the necessity of a new approach to address these problems. Therefore, for this study, an intelligent product search system was developed that enables price comparisons for online shoppers in a more effective manner. In particular, the developed system adopts linguistic price ratings based on fuzzy logic to accommodate user-defined price ranges, and personalizes product recommendations based on linguistic product clusters, which help online shoppers find desired items in a convenient manner.

    Alcoholics Anonymous is not yet fully employed by the medical community as a means to enhance patient outcome. The purpose of this study was to evaluate visitors' use of an Internet course on Alcoholics Anonymous, and to compare how various disciplines learned about, gained access to and participated in the course. Demographic information was collected from 414 visitors to the course. 64% of the 414 respondents received their last educational degree within the last 10 years, and had an interest in the topic of addiction prior to their accessing the site. 294 (71%) of those who accessed the course completed it, and those who accessed it learned about it from various sources other than print advertisement in professional journals. Within the 230 physician respondents, 143 (62%) were psychiatrists, 82 (78%) of whom learned about the Internet course via professional journal. Given the need for further training among physicians in the use of Alcoholics Anonymous, the Internet can be utilized to make information available to a large number of people. Because it allows the user to access information outside the traditional means, the barriers to its use are minimal, and it has the potential to effectively convey useful clinical information.

    Song, In Ho; Kim, Kyung Don; Chung, Sung Chong

    2008-01-01

    This paper proposes a design methodology for a Web-based collaborative system applicable to reverse engineering processes in a distributed environment. By using the developed system, design reviewers of new products are able to confirm geometric shapes, inspect dimensional information of products through measured point data, and exchange views with other design reviewers on the Web. In addition, it is applicable to verifying accuracy of production processes by manufacturing engineers. Functional requirements for designing this Web-based dimensional verification system are described in this paper. ActiveX-server architecture and OpenGL plug-in methods using ActiveX controls realize the proposed system. In the developed system, visualization and dimensional inspection of the measured point data are done directly on the Web: conversion of the point data into a CAD file or a VRML form is unnecessary. Dimensional verification results and design modification ideas are uploaded to markups and/or XML files during collaboration processes. Collaborators review the markup results created by others to produce a good design result on the Web. The use of XML files allows information sharing on the Web to be independent of the platform of the developed system. It is possible to diversify the information sharing capability among design collaborators. Validity and effectiveness of the developed system has been confirmed by case studies

    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.

    The aim of this randomised controlled trial (RCT) was to evaluate the efficacy of a guided internet-based stress management intervention (iSMI) among distressed managers compared with a attention control group (AC) with full access to treatment-as-usual. A total sample of 117 distressed managers, mainly employed in the healthcare, IT, communication and educational sector, were randomised to either iSMI (n=59) or an AC group (n=58). The iSMI consisted of eight modules including cognitive behavioural stress management and positive management techniques. Participants received a minimal and weekly guidance from a psychologist or master-level psychology student focusing on support, feedback and adherence to the intervention. Self-report data were assessed at pre, post and 6 months after the intervention. The primary outcome was perceived stress (Perceived Stress Scale-14). The secondary outcomes included mental and work-related health outcomes. Participants in the iSMI intervention reported significantly less symptoms of perceived stress (d=0.74, 95% CI 0.30 to 1.19) and burnout (d=0.95, 95% CI 0.53 to 1.37) compared with controls, at postassessment. Significant medium-to-large effect sizes were also found for depression, insomnia and job satisfaction. Long-term effects (6 months) were seen on the mental health outcomes. This is one of the first studies showing that iSMIs can be an effective, accessible and potentially time-effective approach of reducing stress and other mental-related and work-related health symptoms among distressed managers. Future studies are needed addressing distressed managers and the potential of indirect effects on employee stress and satisfaction at work. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    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.

    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.

    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

    Tuberculosis (TB) is considered to be a disease of poverty, since its incidence is exacerbated by socioeconomic factors, inconsistent or partial treatment practices, and immigration from endemic countries. A prospective country level study, using a comprehensive dataset of TB incidence and prevalence taken from countries within the World Health Organization (WHO) European region, was conducted. We employed quintile regression to investigate the prospective association between baseline (measured in 2000) and a nation's wealth, level of egalitarianism, migration rate, health-related lifestyle and social capital with TB incidence and prevalence over a 10-yr period (2000-2009). We found that ∼50% of TB variation is accounted for by a nation's wealth and level of egalitarianism. We observed a negative prospective association between logged gross domestic product and TB rates, and a positive prospective association between income inequality and TB. National income levels per capita and income inequality are important predictors for TB incidence and prevalence in the WHO European region. They account for 50% of country-level variation, indicating the importance of a combined absolute and relative socioeconomic disadvantage in the development of TB. These findings also provide a tool for forecasting potential fluctuations in the level of TB epidemics in the WHO European region, with respect to socioeconomic changes.

    International Nuclear Information System (INIS)

    Wagner, H.N. Jr.

    1984-01-01

    All living systems are characterized by an S-shaped growth curve, representing a lag phase, a phase of exponential growth and a plateau. Nuclear medicine is no exception. In one sense, medical imaging modalities, such as plain film and contrast studies, computerized tomography (CT), ultrasound, digital subtraction angiography, conventional nuclear imaging, and PET, are competitive. They compete for space, funds, people, enthusiasm, and interest. For example, in the 1970s the use of radionuclide brain scans dropped sharply in hospitals when CT became available; ultrasound and nuclear medicine studies of the biliary system led to a significant decrease in the use of oral cholecystograpy and intravenous cholangiography. Some predict that nuclear magnetic resonance (NMR) and digital radiography may have a significant impact on CT scanning by 1990, because current NMR images are comparable in anatomic resolution to CT without bone artifacts and, especially important in the 1980s, without ionizing radiation. In the face of all this competition, the continued growth and well-being of the field of nuclear medicine will depend on the degree to which the field can adapt itself to the changing circumstances of medical practice and research in the 1980s. The forces that will shape the future of nuclear medicine will continue to come from both within and outside the field

    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.

    In two previous randomized controlled trials Titov et al. demonstrated significant benefit from an Internet- and email-based treatment programme for social phobia. The present study (Shyness 3) explores whether participants are able to complete this programme independently. A total of 98 individuals with social phobia were randomly assigned to a clinician-assisted computerized cognitive behavioural treatment (CaCCBT) group, a self-guided computerized CBT (CCBT) group, or to a waitlist control group. CaCCBT group participants completed the usual Shyness programme consisting of six online lessons, cognitive behavioural homework assignments, email contact with a therapist, and participation in an online discussion forum. CCBT group participants accessed the same resources except for therapist emails. An intention-to-treat model was used for data analyses. A total of 77% of CaCCBT and 33% of CCBT group participants completed all lessons. Significant differences were found after treatment between CaCCBT and control groups (mean between-groups effect size (ES) for the social phobia measures=1.04), and between the CaCCBT and CCBT groups (mean between-groups ES for the social phobia measures=0.66). No significant differences were found after treatment between the CCBT and control groups (mean between-groups ES for the social phobia measures=0.38). CCBT participants, however, who completed the six lessons made good progress (mean within-group ES for the social phobia measures=0.62). Quantitative and qualitative data indicate that both the CaCCBT and CCBT procedures were acceptable to participants. The reliability of this Internet-based treatment programme for social phobia has been confirmed. The therapist-guided condition was superior to the self-guided condition, but a subgroup of participants still benefited considerably from the latter. These data confirm that self-guided education or treatment programmes for common anxiety disorders can result in significant

    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 related to mammography are written well above the recommended sixth-grade level and likely reflect other IPEMs in diagnostic radiology.

    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.

    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.

    A recent systematic review (2008) described the effectiveness of Internet-based learning (IBL) in health professions education. A comprehensive synthesis of research investigating how to improve IBL is needed. This systematic review sought to provide such a synthesis. The authors searched MEDLINE, CINAHL, EMBASE, Web of Science, Scopus, ERIC, TimeLit, and the University of Toronto Research and Development Resource Base for articles published from 1990 through November 2008. They included all studies quantifying the effect of IBL compared with another Internet-based or computer-assisted instructional intervention on practicing and student physicians, nurses, pharmacists, dentists, and other health professionals. Reviewers working independently and in duplicate abstracted information, coded study quality, and grouped studies according to inductively identified themes. From 2,705 articles, the authors identified 51 eligible studies, including 30 randomized trials. The pooled effect size (ES) for learning outcomes in 15 studies investigating high versus low interactivity was 0.27 (95% confidence interval, 0.08-0.46; P = .006). Also associated with higher learning were practice exercises (ES 0.40 [0.08-0.71; P = .01]; 10 studies), feedback (ES 0.68 [0.01-1.35; P = .047]; 2 studies), and repetition of study material (ES 0.19 [0.09-0.30; P or=89%) in most analyses. Meta-analyses for other themes generally yielded imprecise results. Interactivity, practice exercises, repetition, and feedback seem to be associated with improved learning outcomes, although inconsistency across studies tempers conclusions. Evidence for other instructional variations remains inconclusive.

    2015-01-01

    Background Current estimates from objective accelerometer data suggest that American adults are sedentary for ~7.7h/day. Historically, sedentary behaviour was conceptualized as one end of the physical activity spectrum but is increasingly being viewed as a behaviour distinct from physical activity. Methods Prospective studies examining the associations between screen time (watching television, watching videos and using a computer) and sitting time and fatal and non-fatal cardiovascular disease (CVD) were identified. These prospective studies relied on self-reported sedentary behaviour. Results The majority of prospective studies of screen time and sitting time has shown that greater sedentary time is associated with an increased risk of fatal and non-fatal CVD. Compared with the lowest levels of sedentary time, risk estimates ranged up to 1.68 for the highest level of sitting time and 2.25 for the highest level of screen time after adjustment for a series of covariates, including measures of physical activity. For six studies of screen time and CVD, the summary hazard ratio per 2-h increase was 1.17 (95% CI: 1.13–1.20). For two studies of sitting time, the summary hazard ratio per 2-h increase was 1.05 (95% CI: 1.01–1.09). Conclusions Future prospective studies using more objective measures of sedentary behaviour might prove helpful in quantifying better the risk between sedentary behaviour and CVD morbidity and mortality. This budding science may better shape future guideline development as well as clinical and public health interventions to reduce the amount of sedentary behaviour in modern societies. PMID:22634869

    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

    Full Text Available The purpose of this study is to investigate awareness of librarian’s job prospects, and to do this a survey was conducted with 502 college students in 14 Departments of Library and Information Science around Korea and 753 librarians in libraries and related agencies. The study results are as follows. First, satisfaction with educational curriculum was higher in students than librarians. Second, both students and librarians regarded workplace based practical training as employment requirements and also evaluated certifications and academic performance as important requirements. Third, both groups asked that information on employment rates be available in a timely manner, and perceived that the librarian’s job prospects were not bright. Therefore, in order to improve employment of librarians, it will be necessary to establish a job information system, reorganize the current educational curriculum into a practice-oriented curriculum, and introduce the national curriculum statements (NCS-based curriculum.

    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.

    This study aimed to describe the sleep quantity, sleep quality, and daily rest periods (DRPs) of Japanese permanent daytime workers. Information about the usual DRP, sleep quantity, and sleep quality (Japanese version of the Pittsburgh Sleep Quality Index: PSQI-J) of 3867 permanent daytime workers in Japan was gathered through an Internet-based survey. This information was analyzed and divided into the following eight DRP groups: sleep durations for workers in the sleep duration. The PSQI-J scores for the sleep quality. This study described sleep quantity, sleep quality, and DRP in Japanese daytime workers. It was found that a shorter DRP was possibly associated with poorer sleep quantity as well as quality.

    ABSTRACTThe aim of this study was to assess the usability of a new Internet-based Caregiver Support Service (ICSS) and evaluate its effects on health outcomes of Chinese Canadians who cared for a family member with dementia. Demographic and questionnaire data were collected from 28 participants, and in-depth interviews were conducted with 10 participants. Results showed that non-users reported higher levels of burden post-intervetion, and frequent users showed post-intervention reduction in experienced burden. Traditional beliefs shaped caregivers' needs; also, ethno-cultural-linguistic contexts affected system usability and were associated with usage behaviour. This study indicates that caregivers can benefit from receiving professional support via asynchronous e-mails and a dedicated information web site. The ICSS is a feasible approach for supporting caregivers who prefer an alternative service model. This emerging service requires more research in: enhanced technology design, service delivery models for immigrant caregivers, and evaluation of effectiveness and cost-effectiveness.

    The aim of this study is to investigate whether the Big Five personality traits predict the outcome of Internet-based cognitive behavioural therapy (ICBT) and whether they moderate the outcome between ICBT and face-to-face group cognitive behavioural therapy (GCBT). This study investigated the Big Five personality traits as predictors and moderators of the outcome (tinnitus handicap) in a trial comparing ICBT and GCBT for chronic tinnitus. N = 84 patients with chronic tinnitus were randomised to either ICBT (n = 41) or GCBT (n = 43). A multilevel model for discontinuous change was performed. Higher scores on the "openness" scale of the Big Five Personality Inventory (BFI-10) predicted a lower tinnitus handicap (Tinnitus Handicap Inventory, THI) at post-treatment in ICBT (p self-motivation by the patient in order to have an impact.

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

    2015-02-01

    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.

    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.

    This randomized controlled trial evaluated the efficacy of an Internet-based intervention, which aimed to improve recovery from work-related strain in teachers with sleeping problems and work-related rumination. In addition, mechanisms of change were also investigated. A sample of 128 teachers with elevated symptoms of insomnia (Insomnia Severity Index [ISI] ≥ 15) and work-related rumination (Cognitive Irritation Scale ≥ 15) was assigned to either an Internet-based recovery training (intervention condition [IC]) or to a waitlist control condition (CC). The IC consisted of 6 Internet-based sessions that aimed to promote healthy restorative behavior. Self-report data were assessed at baseline and again after 8 weeks. Additionally, a sleep diary was used starting 1 week before baseline and ending 1 week after postassessment. The primary outcome was insomnia severity. Secondary outcomes included perseverative cognitions (i.e., work-related rumination and worrying), a range of recovery measures and depression. An extended 6-month follow-up was assessed in the IC only. A serial multiple mediator analysis was carried out to investigate mechanisms of change. IC participants displayed a significantly greater reduction in insomnia severity (d = 1.37, 95% confidence interval: 0.99-1.77) than did participants of the CC. The IC was also superior with regard to changes in all investigated secondary outcomes. Effects were maintained until a naturalistic 6-month follow-up. Effects on insomnia severity were mediated by both a reduction in perseverative cognitions and sleep effort. Additionally, a greater increase in number of recovery activities per week was found to be associated with lower perseverative cognitions that in turn led to a greater reduction in insomnia severity. This study provides evidence for the efficacy of an unguided, Internet-based occupational recovery training and provided first evidence for a number of assumed mechanisms of change.

This study includes the cost comparisons with the other means of power production and takes into consideration the environmental costs. The study is shared into five chapters dealing with: 1 - the legacy of the past: todays park of nuclear plants, economical and material status; 2 - the international evolution: the dynamics of nuclear policies worldwide (existing parks and R and D programs), the rise of environmental problems worldwide (CO{sub 2} and the climate convention, nuclear risks, attempts of including environment in the power costs), the choices made for the management of spent fuels in the main countries; 3 - the technological prospects for the power production and use: technologies for the mastery of power demand (residential, industrial and tertiary sectors, power transportation), technologies of power production (production from nuclear, fossil and renewable energies); 4 - prospective scenarios for France: two demand scenarios at the year 2050 vista (energy, electric power), power supply (supply structure with respect to scenarios, nuclear parks, power capacities), environmental aspects (CO{sub 2} emissions, plutonium and minor actinides production); 5 - the economical status of the different scenarios: data preparation, fossil fuel price scenarios, investment and operation costs of the different power production means (nuclear, fossil and renewable energies, natural gas and power distribution networks), comparison between fluxes and cumulated economic costs linked with the different scenarios (investments, exploitation, fuels, R and D, status for 2000 to 2050), time structure of expenditures with respect to the different scenarios (chronology, statuses, kWh costs, sensitivity with respect to the rate of discount, valorization of existing parks in 2050

    Depression is common and treatable with cognitive behavior therapy (CBT), for example. However, access to this therapy is limited. Internet-based interventions have been found to be effective in reducing symptoms of depression. The International Society for Research on Internet Interventions has highlighted the importance of translating effective Internet programs into multiple languages to enable worldwide dissemination. The aim of the current study was to determine if it would be cost effective to translate an existing English-language Internet-based intervention for use in a non-English-speaking country. This paper reports an evaluation of a trial in which a research group in Norway translated two English-language Internet-based interventions into Norwegian (MoodGYM and BluePages) that had previously been shown to reduce symptoms of depression. The translation process and estimates of the cost-effectiveness of such a translation process is described. Estimated health effect was found by using quality-adjusted life years (QALY). Conservative estimates indicate that for every 1000 persons treated, 16 QALYs are gained. The investment is returned 9 times and the cost-effectiveness ratio (CER) is 3432. The costs of the translation project totaled to approximately 27% of the estimated original English-language version development costs. The economic analysis shows that the cost-effectiveness of the translation project was substantial. Hopefully, these results will encourage others to do similar analyses and report cost-effectiveness data in their research reports.

    The Internet currently enables unprecedented ease of access for direct-to-consumer (DTC) genetic testing, with saliva collection kits posted directly to consumer homes from anywhere in the world. This poses new challenges for local jurisdictions in regulating genetic testing, traditionally a tightly-regulated industry. Some Internet-based genetic tests have the capacity to cause significant confusion or harm to consumers who are unaware of the risks or potential variability in quality. The emergence of some online products of questionable content, unsupported by adequate scientific evidence, is a cause for concern. Proliferation of such products in the absence of regulation has the potential to damage public trust in accredited and established clinical genetic testing during a critical period of evidence generation for genomics. Here, we explore the challenges arising from the emergence of Internet-based DTC genetic testing. In particular, there are challenges in regulating unaccredited or potentially harmful Internet-based DTC genetic testing products. In Australia, challenges exist for the Therapeutic Goods Administration, which oversees regulation of the genetic testing sector. Concerns and challenges faced in Australia are likely to reflect those of other comparable non-US jurisdictions. Here, we summarize current Australian regulation, highlight concerns, and offer recommendations on how Australia and other comparable jurisdictions might be more proactive in addressing this emerging public health issue.

    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.

    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.

    Internet-based interventions to prevent depression during adolescence have been implemented in Western countries, but there is a lack of research about its adaptation for use in other countries. Project Competent Adulthood Transition with Cognitive-Behavioral, Humanistic and Interpersonal Training (CATCH-IT) is an Internet-based intervention targeting teens at risk for developing depression. This study explored cultural adaptation of the intervention for use in Mainland China. A pilot study using the English version of CATCH-IT was conducted in Wuhan, China, with adolescents from the Wuhan School of Medicine in 2013. Participants completed a feedback survey to evaluate the format and socio-cultural relevance for each component of the intervention. Twenty students were surveyed (age range 19-23 years). In 2014, Chinese physicians evaluated CATCH-IT and completed a feedback questionnaire. Data obtained were collected and analyzed for recurrent themes. Both groups recommended new modules focusing on Chinese-relevant themes like pressure for academic excellence, filial piety, and balancing school and social life. Physicians agreed to retain the cognitive behavior therapy (CBT) and behavioral activation (BA) modules, and were split on the use of interpersonal therapy (IPT). All experts recommended translation of the content into Mandarin and a majority suggested interactive features and less text. All agreed the Internet serves well as a delivery model; however, dissemination through schools was preferred. The results support cultural adaptation of basic facets of the intervention like language and visuals, and also deeper aspects like IPT and the delivery model. Development of an adaptation should build upon the findings from this study and work to maintain fidelity.

    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

    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

    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.

    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. White was the most common ethnicity (46/75, 61%) of advertisements. It was found that 20-29 years of age accounted for 32 of the 51 advertisements that provided age. Escort, the only legal business title, was the most common role title used (48/75, 64%). In total, 85% (64/75) of advertisements detailed lists of sexual services provided and 41% (31/75) of advertisements noted never offering uncovered services (ie, no condom). Gender and the

    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

    There is little known about the association between breastfeeding and long-term child psychopathology. This study aimed to examine the impact of breastfeeding on child mental health and problem behavior at 14 years and whether this association is confounded by other variables. Data were from a pre-birth prospective study that included mothers and their children followed up from pregnancy to 14 years of the child's age in Brisbane, Australia. The child's anxiety/depression, withdrawal problems, somatic complaints, social problems, thought problems, attention problems, aggression, and delinquency were measured using the Achenbach Youth Self Report at 14 years. Breastfeeding was prospectively assessed at the 6-month follow-up of the study. The analysis was based on 4,502 adolescents who responded to the YSR questionnaire and for whom prospective data were available on breastfeeding. Breastfeeding as reported by mothers when the child was 6 months old predicted reduced symptoms of child mental health and problem behavior at 14 years. The impact of breastfeeding on the child's social problems, attention problems, and aggressive behavior remained statistically significant after controlling for the effect of other variables, such as unplanned pregnancy, maternal mental health, and substance use during pregnancy. Our data suggest that breastfeeding for at least 4 months can have a significant protective effect on a child's social, attention, and aggression problems in early adolescence. Given the limitations of the existing evidence, further research is needed to investigate the robustness of the findings of this study and the mechanisms of long-term association between breastfeeding and reduced social, attention, and aggression problems of the offspring in adolescence.

    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

    We sought to identify predictors of symptomatic recovery in vestibular neuritis. Forty VN patients were prospectively studied in the acute phase (median = 2 days) and 32 in the recovery phase (median = 10 weeks) with vestibulo-ocular reflex, vestibular-perceptual, and visual dependence tests and psychological questionnaires. Clinical outcome was Dizziness Handicap Inventory score at recovery phase. Acute visual dependency and autonomic arousal predicted outcome. Worse recovery was associated with a combination of increased visual dependence, autonomic arousal, anxiety/depression, and fear of bodily sensations, but not with vestibular variables. Findings highlight the importance of early identification of abnormal visual dependency and concurrent anxiety.

    The frequency of urinary tract infection before and during pelvic radiotherapy was studied prospectively in 172 patients who were not catherised and had not had instrumentation for at least 4 weeks prior to radiotherapy. The incidence of urinary tract infection prior to radiotherapy was 17% and a further 17% of patients develped a urinary tract infection during radiotherapy. Mid-stream specimens of urine (MSU) should be examined for infection on a weekly basis during pelvic radiotherapy not only to identify this additional 17% of patients but also to detect those patients who have persistent urinary tract infection in spite of treatment with appropriate antibiotics.

    Few prospective studies, and none in Asians, have systematically evaluated the relationship between blood metabolites and colorectal cancer risk. We conducted a nested case-control study to search for risk-associated metabolite biomarkers for colorectal cancer in an Asian population using blood samples collected prior to cancer diagnosis. Conditional logistic regression was performed to assess associations of metabolites with cancer risk. In this study, we included 250 incident cases with colorectal cancer and individually matched controls nested within two prospective Shanghai cohorts. We found 35 metabolites associated with risk of colorectal cancer after adjusting for multiple comparisons. Among them, 12 metabolites were glycerophospholipids including nine associated with reduced risk of colorectal cancer and three with increased risk [odds ratios per standard deviation increase of transformed metabolites: 0.31-1.98; p values: 0.002-1.25 × 10 -10 ]. The other 23 metabolites associated with colorectal cancer risk included nine lipids other than glycerophospholipid, seven aromatic compounds, five organic acids and four other organic compounds. After mutual adjustment, nine metabolites remained statistically significant for colorectal cancer. Together, these independently associated metabolites can separate cancer cases from controls with an area under the curve of 0.76 for colorectal cancer. We have identified that dysregulation of glycerophospholipids may contribute to risk of colorectal cancer. © 2018 UICC.

    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.

    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.

    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

    To asses the indications and complications of temporary loop ileostomy. This was a prospective cohort study conducted at Isra University Hospital, Hyderabad, Pakistan between February 2003 and August 2006. All patients who had temporary loop ileostomy during that period were included in this study. The indications and various postoperative complications were noted during postoperative hospital stay and subsequently during follow up till stoma were closed. Fifty six patients fulfilled the selection criteria during the study period. Typhoid (enteric) perforation was the most common indication of loop ileostomy accounting for about two thirds of all cases. Other indications were iatrogenic, covering ileostomy for rectal cancers, following resection anastomosis, tuberculosis, blunt abdominal trauma, anastomosis leak and rectovaginal fistula. Post operative skin excoriation was the most common complication while poor siting, transient edema, retraction and high output were other less common complications. Temporary loop ileostomy is the stoma of choice for temporary faecal diversion as most of its complications are manageable conservatively. (author)

    Oculomotor abnormalities, especially slow saccades, have long been recognized in Huntington's disease (HD). To study prospectively horizontal saccade velocity by videonystagmography in 21 patients with genetically confirmed HD. The study included a baseline analysis and a second evaluation after 18.8 +/- 7.1 months. We included a control group of 15 subjects. HD group exhibited decreased saccade velocity when compared with that from a control group (for predictive and unpredictive target). HD patients showed decreased saccade velocity with the passage of time (for predictive target, p < 0.01). Finally we found statistical significant correlation between saccade velocity and triplet length. The measurement of saccade velocity might be an objective method to study the natural evolution of HD, and thus evaluate the effectiveness of future therapies.

    We conducted a prospective study to determine the types of bone anomalies observed in different types of dental agenesia. This prospective series included 30 patients who attended our pluridisciplinary clinic since 1988. There were 22 cases of non syndromal agenesia and 8 cases of syndromal agenesia. Patients consulted for a variety of reasons, no specific sign was found. The diagnosis was based on the panoramic x-ray and confirmed at the genetic consultation. Results were systemized by localization of the agenesia. In all cases, the height of the bone crest was preserved compared with the adjacent teeth. In the anterior part of the maxillary, the bone crest was thin showing a water drop aspect. In the posterior maxillary, there was a decrease in the subsinusal height due to invagination of the floor of the sinus. In the anterior part of the mandible, the crest had a knife blade aspect but no loss of height and in the posterior part, a preserved distance between the residual crest rim and the dental canal. In 60% of the solitary agenesias in the anterior part of the maxillary, augmentation was not required. A sinus graft was required in all cases involving the posterior maxillary. Multiple anterior or lateral agenesias were treated with a parietal graft.

    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)

    Full Text Available Abstract Background Teen mothers face many challenges to successful breastfeeding and are less likely to breastfeed than any other population group in the U.S. Few studies have investigated this population; all prior studies are cross-sectional and collect breastfeeding data retrospectively. The purpose of our qualitative prospective study was to understand the factors that contribute to the breastfeeding decisions and practices of teen mothers. Methods This prospective study took place from January through December 2009 in Greensboro, North Carolina in the U.S. We followed the cohort from pregnancy until two weeks after they ceased all breastfeeding and milk expression. We conducted semi-structured interviews at baseline and follow-up, and tracked infant feeding weekly by phone. We analyzed the data to create individual life and breastfeeding journeys and then identified themes that cut across the individual journeys. Results Four of the five teenagers breastfed at the breast for nine days: in contrast, one teen breastfed exclusively for five months. Milk expression by pumping was associated with significantly longer provision of human milk. Breastfeeding practices and cessation were closely connected with their experiences as new mothers in the context of ongoing multiple roles, complex living situations, youth and dependency, and poor knowledge of the fundamentals of breastfeeding and infant development. Breastfeeding cessation was influenced by inadequate breastfeeding skill, physically unpleasant and painful early experiences they were unprepared to manage, and inadequate health care response to real problems. Conclusions Continued breastfeeding depends on a complex interplay of multiple factors, including having made an informed choice and having the skills, support and experiences needed to sustain the belief that breastfeeding is the best choice for them and their baby given their life situation. Teenagers in the US context need to have

    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. 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. 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. 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. 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.

    An increasing number of parents and practitioners use the Internet for health related purposes, and an increasing number of models are available on the Internet for predicting spontaneous resolution rates for children with vesicoureteral reflux. We sought to determine whether currently available Internet based calculators for vesicoureteral reflux resolution produce systematically different results. Following a systematic Internet search we identified 3 Internet based calculators of spontaneous resolution rates for children with vesicoureteral reflux, of which 2 were academic affiliated and 1 was industry affiliated. We generated a random cohort of 100 hypothetical patients with a wide range of clinical characteristics and entered the data on each patient into each calculator. We then compared the results from the calculators in terms of mean predicted resolution probability and number of cases deemed likely to resolve at various cutoff probabilities. Mean predicted resolution probabilities were 41% and 36% (range 31% to 41%) for the 2 academic affiliated calculators and 33% for the industry affiliated calculator (p = 0.02). For some patients the calculators produced markedly different probabilities of spontaneous resolution, in some instances ranging from 24% to 89% for the same patient. At thresholds greater than 5%, 10% and 25% probability of spontaneous resolution the calculators differed significantly regarding whether cases would resolve (all p calculators. For certain patients, particularly those with a lower probability of spontaneous resolution, these differences can significantly influence clinical decision making.

    On May 7, 1999 an economical study of the overall nuclear file, and in particular, of the back-end part of the fuel cycle and including the reprocessing, was requested by the French Prime Minister. This study includes the cost comparisons with the other means of power production and takes into consideration the environmental costs. The study is shared into five chapters dealing with: 1 - the legacy of the past: todays park of nuclear plants, economical and material status; 2 - the international evolution: the dynamics of nuclear policies worldwide (existing parks and R and D programs), the rise of environmental problems worldwide (CO 2 and the climate convention, nuclear risks, attempts of including environment in the power costs), the choices made for the management of spent fuels in the main countries; 3 - the technological prospects for the power production and use: technologies for the mastery of power demand (residential, industrial and tertiary sectors, power transportation), technologies of power production (production from nuclear, fossil and renewable energies); 4 - prospective scenarios for France: two demand scenarios at the year 2050 vista (energy, electric power), power supply (supply structure with respect to scenarios, nuclear parks, power capacities), environmental aspects (CO 2 emissions, plutonium and minor actinides production); 5 - the economical status of the different scenarios: data preparation, fossil fuel price scenarios, investment and operation costs of the different power production means (nuclear, fossil and renewable energies, natural gas and power distribution networks), comparison between fluxes and cumulated economic costs linked with the different scenarios (investments, exploitation, fuels, R and D, status for 2000 to 2050), time structure of expenditures with respect to the different scenarios (chronology, statuses, kWh costs, sensitivity with respect to the rate of discount, valorization of existing parks in 2050), cost overruns

    The purpose of this study was to characterize the neuropsychiatric profile of elderly patients with schizophrenia and establish a patient registry for prospective ante-mortem and post-mortem studies. Medical records of all chronically institutionalized patients in eight state hospitals who were over the age of 65 and had a chart diagnosis of schizophrenia (N = 528) were reviewed. Of the potential subjects, 192 were excluded because of clinical histories inconsistent with a diagnosis of schizophrenia, 56 because of insufficient information to establish a psychiatric diagnosis, and 122 because of family members' refusal to give consent for autopsy in the event of death. To date, 81 of the remaining 158 patients have undergone neuropsychiatric evaluation with standard assessment instruments. Mini-Mental State scores of the 81 patients indicated severe dementia, and Functional Assessment Scale scores showed that patients required assistance with activities of daily living. All patients were rated as severely ill on the Brief Psychiatric Rating Scale. Ratings on the Scale for the Assessment of Negative Symptoms and the Scale for the Assessment of Positive Symptoms indicated a predominance of negative symptoms over positive. Of 30 patients who have died to date, research autopsies have been conducted on 26. Establishing a well characterized, prospective patient registry for clinicopathologic studies of schizophrenia is feasible but labor intensive. Diagnosis of schizophrenia with a high degree of confidence can be achieved by means of detailed chart review and assessment of current neuropsychiatric functioning with standard rating instruments. These data provide a basis for correlations of clinicopathologic factors.

    Reducing health and economic burdens from diagnostic delay of psychogenic nonepileptic seizures (PNES) requires prompt referral for video electroencephalography (VEEG) monitoring, the diagnostic gold standard. Practitioners make VEEG referrals when semiology suggests PNES, although few semiological signs are supported by well-designed studies, and most VEEG studies neglect to concurrently measure how accurately seizure witnesses can ascertain semiology. In this study, we estimate the value of eyewitness-reported and video-documented semiology for predicting PNES, and we measure accuracy of eyewitness reports. We prospectively interviewed eyewitnesses of seizures in patients referred for VEEG monitoring, to inquire about 48 putative PNES and ES signs. Multiple, EEG-blinded, epileptologists independently evaluated seizure videos and documented the presence/absence of signs. We used generalized estimating equations to identify reliable video-documented PNES and ES signs, and we compared eyewitness reports with video findings to assess how accurately signs are reported. We used logistic regression to determine whether eyewitness reports could predict VEEG-ascertained seizure type. We analyzed 120 seizures (36 PNES, 84 ES) from 35 consecutive subjects. Of 45 video-documented signs, only 3 PNES signs ("preserved awareness," "eye flutter," and "bystanders can intensify or alleviate") and 3 ES signs ("abrupt onset," "eye-opening/widening," and postictal "confusion/sleep") were significant and reliable indicators of seizure type. Eyewitness reports of these 6 signs were inaccurate and not statistically different from guessing. Consequentially, eyewitness reports of signs did not predict VEEG-ascertained diagnosis. We validated our findings in a second, prospective cohort of 36 consecutive subjects. We identified 6 semiological signs that reliably distinguish PNES and ES, and found that eyewitness reports of these signs are unreliable. We offer suggestions to improve the

    Mental illness is common among prisoners, but little evidence exists regarding changes in symptoms in custody over time. To investigate the prevalence and predictors of psychiatric symptoms among prisoners during early custody. In a prospective cohort study, 3079 prisoners were screened for mental illness within 3 days of reception. To establish baseline diagnoses and symptoms, 980 prisoners were interviewed; all remaining in custody were followed up 1 month and 2 months later. Symptom prevalence was highest during the first week of custody. Prevalence showed a linear decline among men and convicted prisoners, but not women or remand prisoners. It decreased among prisoners with depression, but not among prisoners with other mental illnesses. Overall, imprisonment did not exacerbate psychiatric symptoms, although differences in group responses were observed. Continued discussion regarding non-custodial alternatives for vulnerable groups and increased support for all during early custody are recommended.

    This study reports on a prospective pilot trial of intensive hypnotherapy for smoking cessation. The hypnotherapy involved multiple individual sessions (8 visits) over approximately 2 months, individualization of hypnotic suggestions, and a supportive therapeutic relationship. Twenty subjects were randomly assigned to either an intensive hypnotherapy condition or to a wait-list control condition. The target quitting date was 1 week after beginning treatment. Patients were evaluated for smoking cessation at the end of treatment and at Weeks 12 and 26. Self-reported abstinence was confirmed by a carbon-monoxide concentration in expired air of 8 ppm or less. The rates of point prevalence smoking cessation, as confirmed by carbon-monoxide measurements for the intensive hypnotherapy group, was 40% at the end of treatment; 60% at 12 weeks, and 40% at 26 weeks (p < .05).

    Full Text Available Background: Considering the important role of pituitary gland in regulating various endocrine axes and its unique anatomical location, various postoperative complications can be anticipated resulting from surgery on pituitary tumors. We examined and categorized the immediate postoperative complications according to various tumor pathologies. Materials and Methods: We carried out a prospective study in 152 consecutive patients and noted various postoperative complications during neurosurgical intensive care unit stay (within 48 hrs of hospital stay in patients undergoing transsphenoidal removal of pituitary tumors. Results: In our series, various groups showed different postoperative complications out of which, cerebrospinal fluid leak was the commonest followed by diabetes insipidus, postoperative nausea and vomiting, and hematoma at operation site. Conclusion: Various immediate postoperative complications can be anticipated in transsphenoidal pituitary surgery even though, it is considered to be relatively safe.

    Full Text Available Marine microorganisms produce a series of promising enzymes that have been widely used or are potentially valuable for our daily life. Both classic and newly developed biochemistry technologies have been broadly used to study marine and terrestrial microbiological enzymes. In this brief review, we provide a research update and prospects regarding regulatory mechanisms and related strategies of acyl-homoserine lactones (AHL lactonase, which is an important but largely unexplored enzyme. We also detail the status and catalytic mechanism of the main types of polysaccharide-degrading enzymes that broadly exist among marine microorganisms but have been poorly explored. In order to facilitate understanding, the regulatory and synthetic biology strategies of terrestrial microorganisms are also mentioned in comparison. We anticipate that this review will provide an outline of multiple strategies for promising marine microbial enzymes and open new avenues for the exploration, engineering and application of various enzymes.

    We conducted a prospective, randomized study on 84 consecutive patients with 88 acute, traumatic femoral shaft fractures using 32 Grosse-Kempf nails, 29 Russell-Taylor nails, and 27 Synthes nails. Although total operative times and proximal and distal locking times were similar for the three groups, the procedure was faster with the Grosse-Kempf nail. Three proximal fractures could not be locked with the Synthes nail. At first follow-up, we found no significant difference in terms of pain, limp, range of motion, or time to union; however, we removed fewer Synthes nails to resolve patient complaints of pain. Three delayed unions were attributed to fracture distraction. We conclude that all three nails are suitable for the treatment of almost all femoral shaft fractures. A careful analysis of intraoperative technique and instrumentation indicates that all three nails can be used safely and easily once experience is gained. Clinical outcome is similar regardless of the nail chosen.

    During an infection or inflammation, several drug-metabolizing enzymes in the liver are down-regulated, including cytochrome P450 iso-enzymes. Since voriconazole is extensively metabolized by cytochrome P450 iso-enzymes, the metabolism of voriconazole can be influenced during inflammation via reduced clearance of the drug, resulting in higher voriconazole trough concentrations. To investigate prospectively the influence of inflammation on voriconazole metabolism and voriconazole trough concentrations. A prospective observational study was performed at the University Medical Center Groningen. Patients were eligible for inclusion if they were ≥18 years old and treated with voriconazole. Voriconazole and voriconazole-N-oxide concentrations were determined in discarded blood samples. To determine the degree of inflammation, C-reactive protein (CRP) concentrations were used. Subsequently, a longitudinal data analysis was performed to assess the effect of inflammation on the metabolic ratio and voriconazole trough concentration. Thirty-four patients were included. In total 489 voriconazole trough concentrations were included in the longitudinal data analysis. This analysis showed that inflammation, reflected by CRP concentrations, significantly influenced the metabolic ratio, voriconazole trough concentration and voriconazole-N-oxide concentration (all P voriconazole metabolism. The metabolic ratio was decreased by 0.99229 N and the voriconazole-N-oxide concentration by 0.99775 N , while the voriconazole trough concentration was increased by 1.005321 N , where N is the difference in CRP units (in mg/L). This study shows that voriconazole metabolism is decreased during inflammation, resulting in higher voriconazole trough concentrations. Therefore, frequent monitoring of voriconazole serum concentrations is recommended during and following severe inflammation. © The Author 2016.

    Preeclampsia is associated with increased cardiovascular and renal risk. The aim of this prospective cohort study was to characterize the early postpartum blood pressure (BP) profile after preeclampsia. We enrolled 115 women with preeclampsia and 41 women with a normal pregnancy in a prospective cohort study. At 6 to 12 week postpartum, we assessed the prevalence of different hypertensive phenotypes using 24-hour ambulatory BP monitoring (ABPM), as well as the risk of salt sensitivity and the variability of BP derived from ABPM parameters. Among patients with preeclampsia, 57.4% were still hypertensive at the office. Daytime ABP was significantly higher in the preeclampsia group (118.9±15.0/83.2±10.4 mm Hg) than in controls (104.8±7.9/71.6±5.3 mm Hg; P preeclampsia women remained hypertensive on ABPM in the postpartum, of whom 24.3% were still under antihypertensive treatment; 17.9% displayed a white-coat hypertension and 11.6% had masked hypertension. In controls, 2.8% had white-coat hypertension; none had masked hypertension or needed hypertensive treatment. The prevalence of nondippers was similar 59.8% in the preeclampsia group versus 51.4% in controls. High-risk class of salt sensitivity of BP was increased in preeclampsia women (48.6%) compared with controls (17.1%); P preeclampsia. This finding may help identify women who should be included in a postpartum cardiovascular risk management program. URL: https://www.clinicaltrials.gov.

    Internet-based surveys provide a potentially important tool for Inflammatory Bowel Disease (IBD) research. The advantages include low cost, large numbers of participants, rapid study completion and less extensive infrastructure than traditional methods. The aim was to determine the accuracy of patient self-reporting in internet-based IBD research and identify predictors of greater reliability. 197 patients from a tertiary care center answered an online survey concerning personal medical history and an evaluation of disease specific knowledge. Self-reported medical details were compared with data abstracted from medical records. Agreement was assessed by kappa (κ) statistics. Participants responded correctly with excellent agreement (κ=0.96-0.97) on subtype of IBD and history of surgery. The agreement was also excellent for colectomy (κ=0.88) and small bowel resection (κ=0.91), moderate for abscesses and fistulas (κ=0.60 and 0.63), but poor regarding partial colectomy (κ=0.39). Time since last colonoscopy was self-reported with better agreement (κ=0.84) than disease activity. For disease location/extent, moderate agreements at κ=69% and 64% were observed for patients with Crohn's disease and ulcerative colitis, respectively. Subjects who scored higher than the average in the IBD knowledge assessment were significantly more accurate about disease location than their complementary group (74% vs. 59%, p=0.02). This study demonstrates that IBD patients accurately report their medical history regarding type of disease and surgical procedures. More detailed medical information is less reliably reported. Disease knowledge assessment may help in identifying the most accurate individuals and could therefore serve as validity criteria. Internet-based surveys are feasible with high reliability about basic disease features only. However, the participants in this study were engaged at a tertiary center, which potentially leads to a bias and compromises generalization to

    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

    Full Text Available Abstract Background Even though depression and anxiety are highly prevalent in adolescence, youngsters are not inclined to seek help in regular healthcare. Therapy through the Internet, however, has been found to appeal strongly to young people. The main aim of the present study is to examine the efficacy of preventive Internet-based guided self-help problem-solving therapy with adolescents reporting depressive and anxiety symptoms. A secondary objective is to test potential mediating and moderating variables in order to gain insight into how the intervention works and for whom it works best. Methods/design This study is a randomized controlled trial with an intervention condition group and a wait-list control group. The intervention condition group receives Internet-based self-help problem-solving therapy. Support is provided by a professional and delivered through email. Participants in the wait-list control group receive the intervention four months later.
