Mutation-specific reporter for optimization and enrichment of prime editing

Prime editing is a versatile genome-editing technique that shows great promise for the generation and repair of patient mutations. However, some genomic sites are difficult to edit and optimal design of prime-editing tools remains elusive. Here we present a fluorescent prime editing and enrichment reporter (fluoPEER), which can be tailored to any genomic target site. This system rapidly and faithfully ranks the efficiency of prime edit guide RNAs (pegRNAs) combined with any prime editor variant. We apply fluoPEER to instruct correction of pathogenic variants in patient cells and find that plasmid editing enriches for genomic editing up to 3-fold compared to conventional enrichment strategies. DNA repair and cell cycle-related genes are enriched in the transcriptome of edited cells. Stalling cells in the G1/S boundary increases prime editing efficiency up to 30%. Together, our results show that fluoPEER can be employed for rapid and efficient correction of patient cells, selection of gene-edited cells, and elucidation of cellular mechanisms needed for successful prime editing.

Development of an Intervention to Create a Supportive Work Environment for Employees with Chronic Conditions: An Intervention Mapping Approach

Purpose This study describes the development of an evidence-based intervention to create a supportive work environment for employees with chronic conditions. Occupational physicians (OPs) play an important role in guiding organizations in this process of organizational change. Supportive work environments can aid in preventing work-related problems and facilitate sustainable employment. Current workplace interventions for employees with chronic conditions are mainly focused on return to work or a reduction in sick leave at the individual worker's level. This study contributes to the literature an organizational-level intervention which utilizes a preventive approach. Methods Intervention mapping (IM) is a six-step, structured protocol that was used to develop this intervention. In step 1, a needs assessment was conducted to define the problem and explore the perspectives of all stakeholders involved. The program outcomes and the performance objectives of employees with chronic conditions and occupational physicians were specified in step 2. In step 3, appropriate methods and practical applications were chosen. Step 4 describes the actual development of the intervention, consisting of (1) a training for occupational physicians to teach them how to guide organizations in creating a supportive work environment; (2) a practical assignment; and (3) a follow-up meeting. The intervention will be implemented in a pilot study in which occupational physicians will put their acquired knowledge and skills into practice within one of their organizations, which is delineated in step 5. Conclusions IM proved to be a valuable and practical tool for the development of this intervention, aiming to facilitate sustainable employment for employees with chronic conditions.

[Bone growth stimulators for fractures; sensible or not?]

More and more patients with fractures are asking for bone growth stimulators. There are currently 2 types of bone growth stimulators on the market: stimulators using pulsed electromagnetic fields (PEMF) and stimulators using low-intensity pulsed ultrasound (LIPUS). There is insufficient evidence that LIPUS bone growth stimulator treatment is useful in patients with fresh fractures; the effects of LIPUS bone growth stimulation for delayed-union and non-union fractures need more in-depth investigation. There is also insufficient evidence that PEMF bone growth stimulation has beneficial effects on the healing of fresh fractures and delayed-union and non-union fractures. We do not recommend routine use of bone growth stimulators, partly because of the significant costs involved.

Measuring Goal Setting in School-Aged Children: Studying the Effects of Demographic Variables in Regression-Based Norms

The aim of the study was to establish demographically representative norms for tasks measuring goal setting, and more specifically planning and reasoning in children. Three tasks were administered to n = 195 Ukrainian children aged 5.10 to 14.5 years old: the Spatial Working Memory (SWM), the Stockings of Cambridge (SOC) test, and the Naglieri Nonverbal Ability Test (NNAT). Main outcome per test was accuracy: i.e., the total number correct for the SOC and NNAT, and the total amount of incorrect responses for the SWM. Correlations among accuracy measures varied from − 0.51 to 0.60, indicating these tasks measure related but at the same time unique constructs. Higher age was associated with more accurate test performances on all outcome measures. On the NNAT, we found a curvilinear association between age and accuracy, indicating that younger children’s NNAT accuracy scores increased more with age compared with older children. We found a cubic age effect on accuracy for the SWM and SOC: i.e., test scores were relatively stable at younger and older ages, with a curvilinear increase in test scores in the other age groups. Demographically corrected norms were calculated and presented per test. These indicated that sex was not associated with accuracy scores on any of the tests. Last, a higher level of parental education (LPE) was associated with higher accuracy scores, but only on the NNAT. We conclude that demographic variables in norm analyses enhance insight in the scores and allow for application in clinical settings and research.

Perceptions of Alcohol and Alcohol Use among Community Members and Young Adults in Ukraine

Background: Unhealthy alcohol use is a public health issue, prioritized by the World Health Organization (WHO) for prevention and reduction. Ukraine falls in the highest WHO category of "years of life lost" due to alcohol use. Objective: To investigate perceptions of alcohol consumption in a sample of youth and adults in western Ukraine. Methods: In-depth semi-structured interviews were conducted with 38 adult stakeholders (aged 21-63 years), and 81 adolescents and young adults (aged 12-21 years) completed paper-and-pencil open-ended questions. A combined deductive-inductive thematic analysis of these qualitative data resulted in an initial coding scheme for both parts of the data. These initial codes were organized into patterns, which were further condensed to four themes. Results: The four themes that were developed are: (1) The general historical, socio-economic-political situation and its relation to alcohol use, (2) Alcohol in the home and daily environment, (3) Alcohol use, related feelings, peers, family, and burden to health, and (4) Perceptions of the consequences of alcohol (mis)use. Conclusions: Respondents indicated awareness that daily consumption, also in youth, as well as binge drinking and childhood sipping constitute a risk to health. These risks were described in the context of easy availability, low pricing, and peer pressure. The respondents mentioned awareness that alcohol dependence (AD) of parents affected families with the risk of disadvantageous child development. Interventions may include targeting current norms, stigmatizing beliefs and supporting subjects in developing coping skills.

Measuring Visual, Spatial, and Visual Spatial Short-Term Memory in Schoolchildren: Studying the Influence of Demographic Factors and Regression-Based Normative Data

The study aims to establish demographically corrected norms for three computerized tasks measuring different aspects of visual short-term memory (VSTM) in Ukrainian schoolchildren. These tasks measure respectively visual STM (the Pattern Recognition Memory (PRM) test), spatial STM (the Spatial Span (SSP) task), and visual spatial STM (the Paired Associates Learning (PAL) task). All tasks were administered to n = 186 children aged 5.10 years to 14.5 years old to evaluate the influence of demographic variables. Relevant demographic factors that influence task scores (VSTM), i.e., age and level of parental education, are identified and in keeping with the current literature. No sex differences were found. Based on these data, regression-based, demographically corrected norms were established per task. This approach to constructing norms differs from how (worldwide) PRM, SSP, and/or PAL norms have been constructed traditionally. In the latter approach, norms are calculated for each age group separately and without correcting for level of parental education, whereas in the regression-based normative method, multiple regression models are used to compute the expected test scores of an individual (rather than the subgroup means that are used in the traditional approach). Consequently, the regression-based norms for the PRM, SSP, and PAL presented in this paper are individualized, taking into account the unique characteristics of the individual that is tested on these tasks. Last, the confidence intervals of the PRM scores of the Ukrainian schoolchildren and the western norm group largely overlapped, except for the youngest age group, which adds to the literature about cultural effects on cognition.

Interventions Developed with the Intervention Mapping Protocol in Work Disability Prevention: A Systematic Review of the Literature

Purposes Intervention mapping (IM) is a protocol for developing effective behavior change interventions. It has been used for 10 years to develop work disability prevention (WDP) interventions, but it is not known to what extent and with what success. The main objective of this study was to review the effectiveness of these interventions. Secondary objectives were to review their fidelity to the IM protocol, their theoretical frameworks and their content. Methods A search strategy was conducted in MEDLINE, Web of Science, PsycINFO, Pascal, Francis, and BDSP. All titles and abstracts were reviewed. A standardized extraction form was developed. All included studies were reviewed by two reviewers blinded to each other. Results Eight WDP interventions were identified aimed at return to work (RTW; n = 6) and self-management at work (n = 2). RTW interventions targeted workers with stress-related mental disorders (n = 1), low back pain (n = 1), musculoskeletal disorders (n = 1), cancer (n = 2) and gynecological surgery (n = 1). The fidelity to the IM protocol was weaker for the participatory planning group. Matrices of change, change methods, and applications were systematically reported. The main theoretical frameworks used were the attitude-social influence-self efficacy model (n = 4) and the theory of planned behavior (n = 2). Half of the interventions included a workplace component (n = 4). Two interventions were reported as effective, and one partially effective. Conclusion The IM protocol is used in WDP since 2007. The participative dimension appears underused. Few theoretical frameworks were used. Implications are to better consider the stakeholders involvement, and mobilize theoretical frameworks with greater attempts to intervene on the work environment.

Strength exercises during physical education classes in secondary schools improve body composition: a cluster randomized controlled trial

BACKGROUND

Metabolic health in people with obesity is determined by body composition. In this study, we examined the influence of a combined strength exercise and motivational programme -embedded in the school curriculum- on adolescents body composition and daily physical activity.

METHODS

A total of 695 adolescents (11-15y) from nine Dutch secondary schools participated in a one year cluster randomised controlled trial (RCT). In the intervention schools, physical education teachers were instructed to spend 15-30 min of all physical education lessons (2× per week) on strength exercises. Monthly motivational lessons were given to stimulate students to be more physically active. Control schools followed their usual curriculum. The primary outcome measure was body composition assessed by the deuterium dilution technique. Daily physical activity and sedentary behaviour measured by accelerometry served as a secondary outcome.

RESULTS

After 1 year, a 1.6% fat mass difference was found in favour of the intervention group (p = .007). This reflected a 0.9 kg difference in fat free mass (intervention>control; p = .041) and 0.7 kg difference in fat mass (intervention

CONCLUSION

In 11-15 year olds, the combination of strength exercises plus motivational lessons contributed to an improvement in body composition and a smaller decrease in physical activity level.

Changing distribution and abundance of the malaria vector Anopheles merus in Mpumalanga Province, South Africa

Background: The malaria vector Anopheles merus occurs in the Mpumalanga Province of South Africa. As its contribution to malaria transmission in South Africa has yet to be ascertained, an intensification of surveillance is necessary to provide baseline information on this species. The aim of this study was therefore to map An. merus breeding sites in the Ehlanzeni District of Mpumalanga Province and to assess qualitative trends in the distribution and relative abundance of this species over a 9-year period. Methods: The study was carried out during the period 2005-2014 in the four high-risk municipalities of Ehlanzeni District. Fifty-two breeding sites were chosen from all water bodies that produced anopheline mosquitoes. The study data were extracted from historical entomological records that are captured monthly. Results: Of the 15 058 Anopheles mosquitoes collected, 64% were An. merus. The abundance and distribution of An. merus increased throughout the four municipalities in Ehlanzeni District during the study period. Conclusion: The expanded distribution and increased abundance of An. merus in the Ehlanzeni District may contribute significantly to locally acquired malaria in Mpumalanga Province, likely necessitating the incorporation of additional vector control methods specifically directed against populations of this species.

Women Who Love: An Explorative Study on Experiences of Lesbian and Bisexual Women with a Mild Intellectual Disability in The Netherlands

Empirical research that addresses sexual orientation in people with an intellectual disability (ID) is limited, and very little is known regarding the personal experiences of lesbian and bisexual women with ID. This study set out to answer the question: What are the experiences of lesbian and bisexual women with a mild intellectual disability in the Netherlands? Ten lesbian and bisexual women (average age of 33 years) with a mild intellectual disability took part in our study comprising of semi-structured interviews. Participants reported that they had found it hard to talk to others about sensitive subjects such as their sexuality, and had been left to figure out information regarding their sexual orientation without support or guidance. Our results point to a lack of information, sexual education and role models when it comes to lesbian sex and women with an intellectual disability. Social contact was often limited, and participants experienced difficulties finding a partner. Furthermore, participants often had to cope with mental health problems and had struggled with loneliness, depression and addiction. Last but not least, our participants reported that they had been discriminated against. Coming out (revealing your sexual orientation) is not easy when you have an intellectual disability. To enable women with ID who have lesbian or bisexual feelings to understand and secure their sexual rights in their daily lives is important. Therefore, it is necessary to provide support in the following domains: sexual education and training, social contact and assertiveness.

Sexuality and individual support plans for people with intellectual disabilities

BACKGROUND

Sexual rights and sexuality are important aspects of quality of life, also for people with intellectual disabilities (IDs). However, providing support in this area to people with ID poses some challenges. In this study, the content of individual support plan (ISP) documents was analysed to determine the extent to which sexuality and sexual rights are addressed in part of the ISP documents.

METHOD

Content analysis was carried out on a sample of 187 ISP documents from seven different service provider organisations in the Netherlands. First, we conducted a lexical search using terms related to sexuality and sexual health. The retrieved segments were then analysed.

RESULTS

A total of 159 ISP documents (85%) of 60 men and 99 women contained some reference to aspects of sexuality. However, these references were mostly descriptive and offered little guidance in terms of providing support. Moreover, these notations mostly described negative or problematic aspects of sexuality. References to sexual education, treatment, intervention programs or support strategies were rarely found in the ISP documents.

CONCLUSIONS

Although sexuality is addressed in most ISP documents, there is little information available about the provision of professional support in this area that would give people the opportunity to exert sexual rights. As sexuality and exerting sexual rights are important for people with ID as well as for other people, it is recommended that issues surrounding proactive sex education, shared decision-making and the implementation of sexual healthcare plans are addressed in the ISP.

Let's talk about sex: A qualitative study exploring the experiences of HIV nurses when discussing sexual risk behaviours with HIV-positive men who have sex with men

BACKGROUND

Despite prevention efforts, the incidence of sexually transmitted infection among HIV-positive men who have sex with men remains high, which is indicative of unchanged sexual risk behaviour. Discussing sexual risk behaviour has been shown to help prevent sexually transmitted infections among HIV-positive men who have sex with men.

OBJECTIVES

The aim of this study was to identify factors that influence whether - and how - specialised HIV nurses discuss sexual risk behaviour with HIV-positive men who have sex with men. Identifying these factors could indicate how best to improve the frequency and quality of discussions about sexual risk behaviour, thereby reducing sexual risk behaviour and sexually transmitted infections.

DESIGN

Qualitative study, focus groups among HIV nurses.

SETTING

Dutch HIV treatment centres.

PARTICIPANTS

A purposive sample was taken of 25 out of 87 HIV nurses working in one of the 26 specialised HIV treatment centres in the Netherlands. Of the 25 HIV nurses we approached, 22 participate in our study.

METHODS

Three semi-structured focus group interviews were held with 22 HIV nurses from 17 hospitals. Interviews were transcribed verbatim, and thematic analysis was performed.

RESULTS

HIV nurses agreed that discussing sexual risk behaviour is important, but barriers were experienced in relation to doing so. In accordance with the theory of planned behaviour, attitudes, perceived norms and perceived behavioural control were all found to be relevant variables. Barriers to discussing sexual risk behaviour were identified as: dealing with embarrassment, the changing professional role of an HIV nurse, time constraints, and the structure of the consultation.

CONCLUSIONS

To improve the frequency and quality of discussions about sexual risk behaviour with HIV-positive men who have sex with men, our data suggests it would be beneficial to support HIV nurses by developing tools and guidelines addressing what to discuss and how. Using a related topic as a conversational 'bridge' may help nurses to broach this subject with their patients. This would allow HIV nurses to discuss possible risk reduction strategies, such as pre-exposure prophylaxis for HIV-negative partners, condom use, strategic positioning, or sero-sorting.

People with Intellectual Disabilities Talk About Sexuality: Implications for the Development of Sex Education

Existing sex education programmes have failed in involving people with intellectual disabilities in the development of these programmes. Not involving the target population decreases the likelihood that the sex education programme will be effective. This study was conducted to assess the perspectives of people with intellectual disabilities on several sexuality-related topics. Semi-structured interviews were held with 20 people with intellectual disabilities covering topics such as: sex education, relationships, sex, social media, parenthood and support. The reported frequency of sex education the participants receive is low. Their knowledge regarding sex education is mainly limited to topics such as safe sex, contraception and STI's and tends to be superficial. Additionally, knowledge on safe sex does not always translate to safe sex behaviour. Finally, relationships are important for most participants; mainly because they don't want to be alone. Findings from both this study and literature shows that there seems to be a need for high quality sex education. Topics to consider to include are: online relationships, social media and parenthood. It would also be beneficial to focus on sexuality-related skills. Finally, to increase the effectiveness of a sex education programme, it is advisable that a theory-and evidence-based framework, such as Intervention Mapping, is used for its development.

Fetal Alcohol Spectrum Disorders (FASD): an Approach to Effective Prevention

PURPOSE OF REVIEW

The objective of the current contribution is to propose an evidence-based, six-step approach to develop effective programs for prevention of fetal alcohol spectrum disorders.

RECENT FINDINGS

Despite widespread campaigns aimed to reduce prenatal alcohol exposure, the number of affected children continues to be high. Current strategies to reduce prenatal alcohol exposure may be ineffective or counterproductive. However, proven principles of health promotion could be applied to reduce drinking in pregnancy. One such approach is Intervention Mapping (IM), a six-step procedure based on proven principles to change behaviors.

SUMMARY

FASD affects all communities and is an underestimated problem worldwide. Programs based on proven principles of behavior change are warranted. Program developers can use pre-existing protocols and strategies from evidence-based practice, such as Intervention Mapping. Developers who plan their preventive programs in a systematic and evidence-based manner increase the chances of success in reducing prenatal alcohol exposure and FASD.

The Dutch 'Focus on Strength' intervention study protocol: programme design and production, implementation and evaluation plan

BACKGROUND

Overweight youngsters are better in absolute strength exercises than their normal-weight counterparts; a physiological phenomenon with promising psychological impact. In this paper we describe the study protocol of the Dutch, school-based program 'Focus on Strength' that aims to improve body composition of 11-13 year old students, and with that to ultimately improve their quality of life.

METHODS

The development of this intervention is based on the Intervention Mapping (IM) protocol, which starts from a needs assessment, uses theory and empirical research to develop a detailed intervention plan, and anticipates program implementation and evaluation. This novel intervention targets first year students in preparatory secondary vocational education (11-13 years of age). Teachers are the program implementers. One part of the intervention involves a 30 % increase of strength exercises in the physical education lessons. The other part is based on Motivational Interviewing, promoting autonomous motivation of students to become more physically active outside school. Performance and change objectives are described for both teachers and students. The effectiveness of the intervention will be tested in a Randomized Controlled Trial in 9 Dutch high schools.

DISCUSSION

Intervention Mapping is a useful framework for program planning a school-based program to improve body composition and motivation to exercise in 11-13 year old adolescents by a "Focus on Strength".

The Three-Month Effect of Mobile Internet-Based Cognitive Therapy on the Course of Depressive Symptoms in Remitted Recurrently Depressed Patients: Results of a Randomized Controlled Trial

Background: Internet-based cognitive therapy with monitoring via text messages (mobile CT), in addition to treatment as usual (TAU), might offer a cost-effective way to treat recurrent depression. Method: Remitted patients with at least 2 previous episodes of depression were randomized to mobile CT in addition to TAU (n = 126) or TAU only (n = 113). A linear mixed model was used to examine the effect of the treatment condition on a 3-month course of depressive symptoms after remission. Both an intention-to-treat analysis (n = 239) and a completer analysis (n = 193) were used. Depressive symptoms were assessed using the Inventory of Depressive Symptomatology (IDS-SR₃₀) at baseline and 1.5 and 3 months after randomization. Results: Residual depressive symptoms showed a small but statistically significant decrease in the intention-to-treat group over 3 months in the mobile CT group relative to the TAU group (difference: -1.60 points on the IDS-SR₃₀ per month, 95% CI = -2.64 to -0.56, p = 0.003). The effect of the treatment condition on the depressive symptomatology at the 3-month follow-up was small to moderate (Cohen's d = 0.44). All analyses among completers (≥5 modules) showed more pronounced treatment effects. Adjustment for unequally distributed variables did not markedly affect the results. Conclusions: Residual depressive symptoms after remission showed a more favorable course over 3 months in the mobile CT group compared to the TAU group. These results are a first indication that mobile CT in addition to TAU is effective in treating recurrently depressed patients in remission. However, demonstration of its long-term effectiveness and replication remains necessary. © 2015 S. Karger AG, Basel.

Ageing with an intellectual disability: the impact of personal resources on well-being

BACKGROUND

The population of ageing people with mild and moderate intellectual disabilities (ID) is growing rapidly. This study examines how personal resources (physical health, mental health and social networks) impact the well-being of ageing people with ID.

METHODS

Longitudinal survey data on 667 people with a mild or moderate ID were acquired via interviews in 2006 and 2010. Indicators of personal resources (physical health, mental health and social networks) were assessed, as were indicators of well-being (satisfaction with life, happiness and loneliness). Additionally, data on background characteristics and autonomy were gathered.

RESULTS

The results show that age is positively related to decreased mobility and auditory disabilities and negatively related to independent living, autonomy in how one spends one's leisure time and autonomy in decision-making. Longitudinal analyses demonstrated that, with the exception of health that deteriorated, and social satisfaction that improved, almost all variables remained stable over the 4-year period. Further, good physical health in 2006 predicted happiness in 2010.

CONCLUSION

Despite the fact that age is associated with poorer physical and mental health and a smaller social network, this study showed that older people with ID have relatively high levels of well-being. Findings are discussed in the light of coping with ageing and impact of life events.

Prevalence, risk factors and quality of life in Turkish women with urinary incontinence: a synthesis of the literature

BACKGROUND

Urinary incontinence (UI) is not a life threatening condition but it adversely affects physical and mental health, sexual function and quality of life in women.

AIM

To review the related literature to identify prevalence, risk factors and quality of life among only Turkish women.

METHODS

Computerized searches on PubMed, Turkish Medline, EBSCO Host; articles from indexed journals related to the topics in this review and published between 1996 and 30 April 2012 were evaluated. After completion of database searches, a final total of 20 studies were identified that fitted the inclusion criteria.

RESULTS

This review revealed that the prevalence of UI among Turkish women was reported by 16 studies ranged from 16.4% to 49.7%. The most common risk factors were age, number of births, body mass index > 25 kg/m(2), recurrent urinary infection, diabetes mellitus and vaginal delivery. The effect of UI on the quality of life was mild to moderate.

CONCLUSIONS

We found that the prevalence of UI of Turkish women showed a wide range. It is important for health professionals to be aware of the high prevalence of UI in women and to ask about its possible presence. Improving the quality of life in women with UI is an important issue and nurses should direct women to seek psychosocial support. The findings of this review could serve as a source of information for health systems that deal with UI, and it may help to inform health professionals and women with UI on early diagnosis, treatment and management.

Homosexuality among people with a mild intellectual disability: an explorative study on the lived experiences of homosexual people in the Netherlands with a mild intellectual disability

BACKGROUND

Empirical research on homosexuality among people with an intellectual disability (ID) is limited and, to date, very little is known regarding the personal experiences of gay and lesbian people with an ID. This study set out to answer the question: What are the lived experiences of a specific cohort of homosexual people with an intellectual disability living in the Netherlands?

METHOD

To answer this question, a qualitative study was performed in which 21 people with a mild ID were interviewed via semi-structured interviews. In this study, 19 participants were men and two were women (average age = 40.5 years).

RESULTS

Participants reported positive and negative experiences, and talked about their gay or lesbian identity. Almost half of the participants (n = 10) reported that they had experienced sexual abuse including partner violence (n = 6). Additionally, they indicated that there was a lack of support for homosexual people with an ID.

CONCLUSION

Specific problems impact the lives of homosexual people with ID, namely the high prevalence of negative sexual experiences, the lack of support, training and sex education, and their search for a suitable partner.

Determinants of condom use among HIV-positive men who have sex with men

The main objectives of this study were to identify the determinants of condom use among HIV-positive men having anal sex with HIV-negative men or men of unknown HIV status and moderators of the intention-behaviour relationship. A cohort of 237 sexually active HIV-positive men having sex with men was followed over a period of six months. The cognitive variables measured were guided by an extended version of the theory of planned behaviour. Results indicated that past behaviour (odds ratio [OR] = 9.75; 95% confidence interval [CI]: 4.48-21.26), intention (OR = 3.13; 95% CI: 1.25-7.81), self-efficacy (OR = 3.62; 95% CI: 1.40-9.37) and use of sex drugs (OR = 0.16; 95% CI: 0.06-0.45) contributed to the prediction of 100% condom use. Self-efficacy also interacted with intention as a significant moderator of the intention-behaviour relationship (OR = 20.96; 95% CI: 2.90-151.51). Interventions promoting condom use should increase self-efficacy to use condoms and target users of sex drugs.

Evaluation of a risk assessment questionnaire to assist hepatitis C screening in the general population

Many individuals with hepatitis C virus (HCV) infection are undiagnosed. This study evaluates a risk assessment questionnaire, developed for use online to target blood-screening for HCV. Two hundred and eighty-nine patients with known HCV status completed a written questionnaire on prominent HCV risk factors. Questionnaires generated advice to seek testing if at least one risk factor was reported. Agreement of the testing advice with the HCV status of respondents was evaluated. Subsequently, we validated our questionnaire among 985 patients of an outpatient clinic for sexually transmitted infections. The post-test-probability-of-disease (PTPD) and diagnostic gain (PTPD minus prior probability of disease) were calculated. The questionnaire's sensitivity and specificity were 84.6% and 63.8%, respectively, and higher in the STI clinic patients. The PTPD of positive testing advice was 72.5% given HCV prevalence of 53.0%, yielding a diagnostic gain of 19.5%. Applying the estimated prevalence in the general Dutch population (0.1-0.4%), and the anticipated prevalence in the online project (1.0-6.0%), yielded diagnostic gains of 0.13-0.53% and 1.3-7.0%, respectively. We conclude that our questionnaire succeeded in selecting at-risk individuals as its testing advice agreed well with the HCV status. We suggest that the questionnaire be used online as a selection tool for HCV blood-screening in the general population.

Social-cognitive determinants of HIV risk-taking intentions among men who date men through the Internet

The present study was set up to investigate social-cognitive determinants of HIV-risk precautionary intentions among men who have sex with men (MSM), who meet sex partners on the Internet. Participants were enrolled through the major gay chat room in The Netherlands, www.chatboy.nl, and were asked to complete an online questionnaire. Theory of Planned Behaviour variables attitude, subjective norm, and perceived control explained 55% of the variance in intention to use condoms for anal sex with future e-dates. Adding descriptive norm, personal norm and anticipated regret explained 70%. Sexual fantasies and HIV-status had unique effects on intentions. Differences between high and lower intenders are presented. Limitations of the study are discussed and objectives for an intervention to promote condom use are given.

Theory- and evidence-based intervention to improve adherence to antiretroviral therapy among HIV-infected patients in the Netherlands: a pilot study

The objectives of this study were to describe and pilot-test a theory- and evidence-based intervention to improve adherence of HIV-infected patients with antiretroviral medication. Twenty-six treatment-experienced patients (>6 months on treatment) participated in a within-subject comparison design. Adherence was measured electronically with Medication Event Monitoring System (MEMS) caps for at least 5 months: 2 months before the intervention and 3 months during the intervention. MEMS data were used to measure the outcome of the intervention, but also served as feedback to participants during the intervention. Mean adherence during the month before intervention was compared to mean adherence during the third month of intervention. Data for the process evaluation were gathered through direct observation and semi-structured interviews. Adherence improved significantly during the intervention (Z = -2.1, p < 0.05). Mean adherence (percentage of prescribed doses taken within correct time interval) before the intervention was 81.8% compared to 92.5% during the third month of the intervention. More than 65% of the nonadherent patients (<95% adherence) before the intervention were adherent during the third month of the intervention. Both health care professionals and patients positively evaluated the intervention protocol and the electronic measurement of adherence. The only critique from some patients was the lack of userfriendliness of the MEMS cap and its medication container (size and shape). It can be concluded that the proposed intervention fits in standard care procedures, can be executed by trained HIV nurses, seems to improve adherence to antiretroviral medication, and is positively evaluated by the users. Large-scale and long-term research is warranted.

Process evaluation of two environmental nutrition programmes and an educational nutrition programme conducted at supermarkets and worksite cafeterias in the Netherlands

INTRODUCTION

This article describes the process evaluation of two environmental programmes and an educational nutrition programme, implemented at supermarkets and worksite cafeterias. Studies conducted earlier, indicated that the programmes had no effect on consumers' eating behaviour. Consequently, the more specific purpose of the present study was to identify explanations for the ineffectiveness of the programmes and to formulate recommendations for future programmes.

MATERIALS AND METHODS

The environmental programmes included labelling of healthy products and increasing the range of healthy foods on offer. The education programme consisted of several elements, such as brochures and a self-help guide. Semi-structured interviews were conducted with 21 managers of supermarkets and worksite cafeterias where the programmes were implemented.

RESULTS

Although materials were not always entirely compatible with the different supermarkets and worksite cafeterias, the degree of implementation was satisfactory. According to the managers, the programmes were not striking enough, the labelling would have been more effective if it had discriminated between different brands of a product, and the number of new products was too small compared with the total range of foods on offer.

CONCLUSIONS

The findings suggest that programmes should be promoted intensively. Furthermore, the relevant manufacturers and wholesalers supplying worksite cafeterias should be encouraged to increase their range of suitable low-fat products. Finally, the feasibility and possible effects of brand-specific labelling should be investigated further.

Designing a quality improvement intervention: a systematic approach

Most quality improvement or change management interventions are currently designed intuitively and their results are often disappointing. While improving the effectiveness of interventions requires systematic development, no specific methodology for composing intervention strategies and programmes is available. This paper describes the methodology of systematically designing quality of care improvement interventions, including problem analysis, intervention design and pretests. Several theories on quality improvement and change management are integrated and valuable materials from health promotion are added. One method of health promotion-intervention mapping-is introduced and applied. It describes the translation of knowledge about barriers to and facilitators of change into a concrete intervention programme. Systematic development of interventions, although time consuming, appears to be worthwhile. Decisions that have to be made during the design process of a quality improvement intervention are visualised, allowing them to serve as a starting point for a systematic evaluation of the intervention.

Predicting condom use with casual and steady sex partners among drug users

In many Western societies, drug users are accountable for heterosexual transmission of HIV. Although various studies have shown that safe sex is not a common practice among drug users, we still have little understanding of the factors that determine their use of condoms in their sexual relationships with steady or casual partners. The objective of this study is to gain more insight into the determinants of drug users' condom use with steady and casual sex partners. In a study conducted among 103 Dutch drug users, the participants indicated their intentions, vulnerability, attitude, personal norms, subjective norms, descriptive norms, self-efficacy and response efficacy regarding condom use with steady and casual partners. The results showed that some drug users had borrowed used syringes and that most drug users practise unsafe sex, especially with steady partners. Most drug users were hardly motivated to start using condoms. The study further showed that antecedents of condom use differ with regard to steady sex partners and casual sex partners. Self-efficacy and subjective norms were predictors of intentions to use condoms with steady partners; intention to use condoms with casual partners was only predicted by self-efficacy. These differences should be taken into account when designing AIDS prevention interventions to encourage use of condoms.

The additional value of anticipated regret and psychopathology in explaining intended condom use among drug users

Abstract In this study we examine determinants of intended condom use with casual and steady sex partners among drug users. Our aim was to find out whether anticipated regret and psychopathology represent additional factors in explaining condom use behaviour, on top of the constructs defined in traditional psychosocial models of behaviour. A questionnaire measuring intentions, attitude, beliefs, personal norm, subjective norm, descriptive norm, self-efficacy and anticipated regret toward condom use with steady and casual sex partners, and the Symptom Checklist '90 (to measure dimensions of psychopathology) were handed out to 150 Dutch drug users. The results showed that intended condom use with steady sex partners was mainly predicted by self-efficacy, personal norm and anticipated regret (total R2 = 0.41). Lower feelings of hostility and a more positive personal norm, subjective norm and attitude significantly predicted intended condom use with casual sex partners (total R2 = 0.24). The results also showed that intended condom use with steady sex partners seems to result from anticipating possible barriers, whereas condom use with casual sex partners is largely a matter of having safe sex norms. Practical implications of this study for Aids-preventive campaigns are also discussed.

Public reactions to people with HIV/AIDS in The Netherlands

A national telephone survey was conducted to (a) assess present-day public reactions to people with HIV/AIDS in the Netherlands, (b) measure how knowledge about highly active antiretroviral therapy (HAART) is related to public reactions to people with HIV/AIDS, and (c) investigate determinants of willingness to have personal contact with people with HIV/AIDS. Dutch adults (N = 751) participated in a telephone interview conducted to measure cognitive, emotional, and behavioral reactions to people with HIV/AIDS. This study has shown that public reactions to people with HIV/AIDS seem to be moderately positive in the Netherlands. Knowledge about HAART is related to lower risk perceptions, a positive attitude toward homosexuals, less fear, and more willingness to have personal contact with people with HIV/AIDS. In particular, cognitive and emotional factors are meaningfully related to willingness to have personal contact with people with HIV/AIDS. Implications for Dutch AIDS educational campaigns aimed at stigma reduction are discussed.

Evoked fear and effects of appeals on attitudes to performing breast self-examination: an information-processing perspective

The effect of fear arousal on attitude toward participating in early detection activities [i.e. breast self-examination (BSE)] was studied from an information-processing perspective. It was hypothesized that fear arousal motivates respondents to more argument-based processing of fear-relevant persuasive information. Respondents first read information about breast cancer in which fear was manipulated. After measuring fear arousal, respondents read a persuasive message about performing BSE. Analyses with reported fear, but not manipulated fear, found support for the hypothesis. Respondents who reported mild fear of breast cancer based their attitude toward BSE more on the arguments provided than respondents who reported low fear of breast cancer. This finding suggests that the use of fear arousal may be an efficient tool in health education practice. However, alternative interpretations are provided, in addition to the suggestion to be careful with using fear arousal in health education messages.

The determinants of health care seeking behaviour of adolescents attending STD clinics in South Africa

The study investigated the determinants of delay behaviour in health care seeking in a sample of 292 adolescent patients (20 years and younger) with STD symptoms. Fifty six percent (56%) of the adolescents sought health care within the first 6 days of noticing symptoms, 23% waited between 7 to 10 days and 21% waited longer than 10 days before seeking health care. Early health care seeking was determined by perceived seriousness of STDs, an absence of self treatment prior to seeking care and positive attitudes regarding personal autonomy in condom use behaviour. Facilitation of early health care seeking remain critical in curbing the threat of AIDS among the South African youth.

Health care seeking behaviour of patients with sexually transmitted diseases: determinants of delay behaviour

The study aimed to determine the factors associated with a delay in seeking health care for symptoms of sexually transmitted diseases (STDs) among a sample of 1482 patients attending STD clinics. Of the sample 78% were male, 58% sought help from the clinic within the first 6 days of noticing symptoms, 24% waited between 7 and 10 days and 17% waited longer than 10 days before seeking health care. Patients who delayed were those who treated themselves prior to seeking health care, who were female, whose friends waited before seeking treatment, who held misconceptions regarding the cause of STDs, who perceived STDs not to be serious and who valued personal autonomy in sexual behaviours less and had less positive outcome expectations of refusing sex. The data suggest that targeted interventions should be directed specifically at women and the youth. Early health care seeking could be facilitated through improved basic knowledge regarding STDs, control over one's own sexual behaviour and social support for early health care seeking.

Impact of HIV-positive speakers in a multicomponent, school-based HIV/STD prevention program for inner-city adolescents

Qualitative and quantitative data from Safer Choices, a school-based multicomponent HIV prevention program, were examined to determine the impact of HIV-positive speakers on inner-city adolescents' HIV risk perception and empathy for people with HIV or AIDS. Inductive analyses were used to assess student reactions to speakers. Multilevel regression modeling techniques were used to analyze student survey data (n = 1,491) to determine the effect of speakers alone, as well as in combination with the multicomponent intervention, and a knowledge-based curriculum (comparison condition). Results showed that speakers were highly popular with students and teachers, and had a positive short-term impact on students' attitudes. Although not statistically significant, the combination of intervention and speakers had the greatest impact on outcome variables. Integrating HIV-positive speakers into multicomponent programs may have a positive impact on inner-city youth. Utilizing speakers without other educational components may have minimal effects. Strategies for training and utilizing HIV-positive speakers in school settings are included.

Determinants of condom-use behaviour among STD clinic attenders in South Africa

This cross-sectional study analyses determinants of condom-use behaviour among patients attending dedicated STD clinics in South Africa. A structured interviewer-administered survey was conducted among 1473 patients. Patients' beliefs and attitudes towards condom use in general, as well as their personal condom-use behaviour were measured. Their perceptions, regarding the social influence of their partners and friends on their condom use, and of their self-efficacy in using condoms, while infected with an STD were also measured. Condom use, as a dependent variable, was examined and patients were placed in a pre-contemplation stage if they had never used a condom, contemplation if they had seriously thought of using a condom, some action stage if they sometimes used a condom and regular action stage if they used a condom every time. The relationships between the stages of change, as dependent variables, and the independent variables were investigated for both those patients with steady partners and those with outside partners. This was performed by stepwise multiple regression analyses. The variables that significantly explained stages of change were similar for patients with steady partners and those with outside partners. In both partner groups communication was the variable most strongly associated with the use of condoms. General self-efficacy in condom use, self-efficacy in condom use with a partner and attitudes towards the use of condoms played a role in determining patients' different stages of change.

[How effective are smoking cessation campaigns?]

An important risk factor, single as well as combined with other factors, for the development of cancer is tobacco smoking. In the Netherlands 37% of the adult men smoke, and 30% of the women. It is estimated that 20% of the now living population will eventually die from the consequences of smoking. Besides stimulating youngsters not to take up smoking, helping smokers to stop is preventative for the evolution of cancer. However, how effective are the attempts that are currently accomplished in this field? In this contribution, the quit-rates that the different methods produce will be described, over and above the 5% of smokers who yearly succeed in quitting on their own. These rates vary from 5% among the general population resulting from a mass media led campaign. Finally, some critical comments will be given on governmental policies.

STD-related knowledge, beliefs and attitudes of Xhosa-speaking patients attending STD primary health-care clinics in South Africa

The primary aim of this study was to describe patients at sexually transmitted disease (STD) clinics in Cape Town, South Africa, in terms of gender, education and age differences relative to their STD knowledge and beliefs, their condom use, as well as their attitudes towards condom use and their condom-use behaviour. The information was collected with a view to developing a health education intervention. Structured interviews were conducted with 2978 randomly sampled Xhosa-speaking STD clinic attenders about their knowledge, beliefs and practices regarding STDs and related behaviours. More males (75%) than females (25%) presented for STD treatment. The majority of patients (92%) were younger than 35 years. Female patients were found to be more aware than male patients of the sexual nature of STD transmission, valued personal autonomy in sexual behaviour and expressed a greater need to use condoms. Males perceived STD symptoms to be more serious, had more misconceptions about the cause of STDs and also more negative beliefs and attitudes towards condom use. Only 34.9% of the patients reported using condoms in the last 6 months while only 24.5% reported regular use. Those who reported condom use were more knowledgeable about the sexual transmission of STDs and the effects of STDs on the neonate. They also had fewer misconceptions about the causes of STDs and perceived STD symptoms to be more serious, attached greater value to personal autonomy in sexual behaviour and condom use and had more positive outcome expectancies of refusing sex than those who never used condoms. The data suggest that targeted interventions directed at males will have to address their inadequate knowledge regarding STDs in terms of transmission, causes, consequences, prevention and cure. Their negative beliefs and attitudes towards condoms will need special attention, especially in view of their multiple partner behaviour. Interventions directed at females will need to improve their knowledge regarding STD consequences, causes, recognition of symptoms as well as improve their knowledge of aspects of prevention and cure. All interventions must facilitate personal autonomy in decision making about sexual behaviour and condom use for both men and women, through skills development programmes that promote self-efficacy in the individual and instil a culture of mutual respect of such in the community.

Evidence-based nursing practice: both state of the art in general and specific to pressure sores

The importance of research-based practice in nursing has been frequently stressed, and a number of nursing studies have been conducted whose results enable nursing to improve knowledge and practice. This study reports a literature review in which the current status of knowledge and research utilization with regard to pressure sores is described. This review first gives an overview of studies on knowledge utilization in general and shows that the spontaneous diffusion of knowledge is inappropriate. Furthermore, an overview of planned research utilization activities focusing on pressure sore prevention and treatment in nursing is presented. The results of these studies show that planned research utilization activities performed in individual organizations lead to positive outcomes in almost all cases. Therefore, it could be concluded that implementing planned research utilization activities in individual health care institutions seems to be an effective strategy to decrease pressure sore incidence and prevalence rates.

Targeted prevention for people with HIV/AIDS: feasible and desirable?

People with HIV/AIDS are rarely chosen as a target group for prevention activities. In this paper we look at empirical and theoretical evidence for the feasibility and desirability of directing preventive interventions at HIV-positives. Research data on the behaviour and motivation of HIV-positives suggests that the differences between HIV-positives and HIV-negatives and those who are unaware of their HIV-status are not large. However, specific determinants of behaviour, such as responsibility for others or the risk of superinfection, have seldom been measured. Effective interventions targeting at HIV-positives and focussing on prevention are lacking. Fear of increased stigmatization has been used as an argument against focussing prevention activities at HIV-positives. Theoretically that argument is probably not correct: positive coping with HIV may invite positive reactions. The conclusion is that HIV-positives should be chosen as a special target group for additional planned preventive interventions. Because people need to be aware of their HIV status, testing and treatment sites are adequate settings. Effective interventions should be developed on the basis of theory and evidence about the specific determinants of risk behaviour of HIV-positives: protecting oneself for superinfection and protecting one's partner.

Health education in television entertainment--Medisch Centrum West: a Dutch drama serial

World-wide a number of groups have sought ways to incorporate health messages into television entertainment like popular drama and soap serials. In the Netherlands, the Heart Foundation incorporated its cardiovascular health message in several episodes of a popular Dutch hospital serial called Medisch Centrum West. To obtain greater insight into the impact of this so-called 'entertainment-education (E & E) strategy', an evaluation study was carried out. Medisch Centrum West was both entertaining and informative at the same time. Although viewers were well aware that the programme included a health message, they did not find it intrusive to their enjoyment of the storyline. It was interesting to learn that fans were more tolerant and positive towards the E & E strategy than non-fans. Age, sex and education level explained only 5% of the variance.

The learning curve: health education in STI clinics in South Africa

This qualitative study aims to assess health education practice in sexually transmitted infection (STI) clinics in South Africa with a view to develop improved health education programs in such clinics. Health workers' knowledge of and attitudes towards health education practice, their perceived health education skills, the content of health education in STI clinics and the organizational structure as context for health education were investigated. In-depth interviews were conducted with 18 health care workers practicing in the area of STI control. A lack in knowledge and skills required for effective health education practice was reported. The constraints posed by health workers' current knowledge and skills around health education and the organizational structure in terms of the absence of policy and protocols to govern health education, limited time, space and resources, impede on the actual practice of health education. It seems that these obstacles to health education facilitate a biomedical approach to STI management. This approach is further portrayed in the power dynamics between the health workers as well as between health workers and patients. The data suggest that a health education intervention needs to be directed at an individual level namely at health workers and at the organizational level, i.e. the clinic that provides the context for health education. The newly adopted district health system which equally embraces medical care and health promotion augers well for a holistic management of STIs in South Africa. This would ensure the recognition of all categories of health workers' contributions to health education within their own functions, strengths and time limitations.
