A longitudinal pre-post study: An evaluation of the Department of the Air Force bundled occupational fall prevention efforts.

INTRODUCTION: Fall injuries are the second leading cause of traumatic injury and death for all US workers and are a leading injury concern for the Department of the Air Force (DAF). Bundled interventions can improve the likelihood of injury reduction, especially in large, heterogeneous working populations. In 2013, the DAF implemented the "Air Force Fall Prevention Focus," a bundled intervention of prevention efforts designed to reduce occupational fall injury events among DAF members. The purpose of this study is to describe the burden and risk factors associated with fall injuries and evaluate the effectiveness of the Fall Prevention Focus in reducing the burden of fall injuries. METHODS: The National Institute for Occupational Safety and Health (NIOSH) partnered with the US Air Force Safety Center (AFSEC) to examine the impact of the Fall Prevention Focus as a bundled intervention. Injury events included a narrative description of the injury event, demographics, work environment, job tasks, and other structured details. Descriptive statistics and pre-post longitudinal modeling were used to evaluate changes in fall injury rates. RESULTS: The Fall Prevention Focus Implementation (2013-2018) resulted in an annual 10.4% (95% confidence interval [CI]: 8.5%, 12.2%) reduction, and a 6-year cumulative 48.3% (95% CI: 41.4%, 54.3%) reduction in fall injury event rates by 2018. DISCUSSION: Safety in the DAF involves a comprehensive approach. Documenting the impact of the Fall Prevention Focus may help translate these findings to improve fall prevention efforts in other sectors of the military and high fall-risk industries in the private sector, such as construction.

Introducing activation functions into segmented regression model to address lag effects of interventions.

The interrupted time series (ITS) design is widely used to examine the effects of large-scale public health interventions and has the highest level of evidence validity. However, there is a notable gap regarding methods that account for lag effects of interventions.To address this, we introduced activation functions (ReLU and Sigmoid) to into the classic segmented regression (CSR) of the ITS design during the lag period. This led to the proposal of proposed an optimized segmented regression (OSR), namely, OSR-ReLU and OSR-Sig. To compare the performance of the models, we simulated data under multiple scenarios, including positive or negative impacts of interventions, linear or nonlinear lag patterns, different lag lengths, and different fluctuation degrees of the outcome time series. Based on the simulated data, we examined the bias, mean relative error (MRE), mean square error (MSE), mean width of the 95% confidence interval (CI), and coverage rate of the 95% CI for the long-term impact estimates of interventions among different models.OSR-ReLU and OSR-Sig yielded approximately unbiased estimates of the long-term impacts across all scenarios, whereas CSR did not. In terms of accuracy, OSR-ReLU and OSR-Sig outperformed CSR, exhibiting lower values in MRE and MSE. With increasing lag length, the optimized models provided robust estimates of long-term impacts. Regarding precision, OSR-ReLU and OSR-Sig surpassed CSR, demonstrating narrower mean widths of 95% CI and higher coverage rates.Our optimized models are powerful tools, as they can model the lag effects of interventions and provide more accurate and precise estimates of the long-term impact of interventions. The introduction of an activation function provides new ideas for improving of the CSR model.

Guide Development for eHealth Interventions Targeting People With a Low Socioeconomic Position: Participatory Design Approach.

BACKGROUND: People with a low socioeconomic position (SEP) are less likely to benefit from eHealth interventions, exacerbating social health inequalities. Professionals developing eHealth interventions for this group face numerous challenges. A comprehensive guide to support these professionals in their work could mitigate these inequalities. OBJECTIVE: We aimed to develop a web-based guide to support professionals in the development, adaptation, evaluation, and implementation of eHealth interventions for people with a low SEP. METHODS: This study consisted of 2 phases. The first phase involved a secondary analysis of 2 previous qualitative and quantitative studies. In this phase, we synthesized insights from the previous studies to develop the guide's content and information structure. In the second phase, we used a participatory design process. This process included iterative development and evaluation of the guide's design with 11 professionals who had experience with both eHealth and the target group. We used test versions (prototypes) and think-aloud testing combined with semistructured interviews and a questionnaire to identify design requirements and develop and adapt the guide accordingly. RESULTS: The secondary analysis resulted in a framework of recommendations for developing the guide, which was categorized under 5 themes: development, reach, adherence, evaluation, and implementation. The participatory design process resulted in 16 requirements on system, content, and service aspects for the design of the guide. For the system category, the guide was required to have an open navigation strategy leading to more specific information and short pages with visual elements. Content requirements included providing comprehensible information, scientific evidence, a user perspective, information on practical applications, and a personal and informal tone of voice. Service requirements involved improving suitability for different professionals, ensuring long-term viability, and a focus on implementation. Based on these requirements, we developed the final version of "the inclusive eHealth guide." CONCLUSIONS: The inclusive eHealth guide provides a practical, user-centric tool for professionals aiming to develop, adapt, evaluate, and implement eHealth interventions for people with a low SEP, with the aim of reducing health disparities in this population. Future research should investigate its suitability for different end-user goals, its external validity, its applicability in specific contexts, and its real-world impact on social health inequality.

Assessing eating and swallowing in adults born with intellectual and motor disabilities: Face and content validity of a Swedish translation of the Dysphagia Assessment Package.

PURPOSE: Adults born with intellectual disabilities (ID) and motor disabilities (MD) have higher risk of dysphagia and should be assessed to decrease risk of severe complications. However, standardised assessment tools in Swedish are lacking. METHODS: The Dysphagia Assessment Package (DAP) was cross-culturally translated from English to Swedish (DAP-SE) and tested for content validity by an expert group. Face validity was assessed by five speech and language therapist (SLT) during meal observations (n = 10), and the clinical relevance was reported in a study-specific questionnaire. RESULTS: The DAP-SE was culturally adapted within the process of translation and was found to contain clinically relevant aspects to assess and suggest further interventions for adults with ID and MD. Face and content validity was confirmed by the expert group. CONCLUSION: This study, in which the DAP-SE was tested in a small sample size, provides the first indications of the instrument's validity with respect to evaluating mealtimes, swallowing function and swallowing safety in adults born with ID and MD. The study adds to the knowledge on how to translate and culturally adapt an assessment tool to clinically assess dysphagia on a complex and vulnerable patient group.

Training support workers about the overmedication of people with intellectual disabilities: an Australian pre-post pilot study.

BACKGROUND: There is evidence that psychotropic medications are overprescribed and overused to manage behaviours of concern for people with intellectual disabilities. Disability support workers and support staff lack education and training on the administration and safety of psychotropic medication use. This study aimed to test the applicability and preliminary efficacy of SPECTROM, an education programme developed in the UK, in an Australian context. METHODS: The training comprises two parts: Module 1 encompasses psychotropic medications, their use and side effects. Module 2 focuses on non-pharmacological interventions for supporting people with behaviours of concern. Thirty-three participants attended the training course and completed pre-training and post-training surveys on the Psychotropic Knowledge Questionnaire and Management of Aggression and Violence Attitude Scale-Revised at four time points: pre-training, 2 weeks, 3 months and 5 months post-training. RESULTS: Psychotropic Knowledge Questionnaire scores showed statistically significant post-training improvement at all post-training time points (P < 0.05). Management of Aggression and Violence Attitude Scale-Revised scores were high at pre-training and did not change significantly at any of the post-training survey time points. A 2-week post-training feedback questionnaire reported 80% agreement that the training programme was appropriate, useful and valid. Only 36% of participants completed questionnaires at all time points. CONCLUSIONS: SPECTROM training increased staff knowledge of psychotropic medications, yet loss of participants was high. Further refinement of the applicability of the training for the Australian context and evaluation of the feasibility of implementation, clinical and cost-effectiveness of the programme are required.

How does a school-based intervention impact students' social cognitions on reducing sedentary behavior over 14 months?

Despite sedentary behavior being ubiquitous in students and detrimental to health, interventions specifically targeting it are mostly restricted to leisure time screen time reduction. With six weekly sessions alongside a poster campaign and an additional teacher intervention, the Let's Move It trial delivered environmental and psychological strategies to increase physical activity (PA) and reduce sedentary behavior (SB) in vocational schools, an understudied environment for behavioral interventions. Participants in the intervention arm considerably reduced sedentary time post-intervention. To investigate how social cognitions about restricting SB, as defined by the Reasoned Action Approach, change in intervention and control arms, self-reported data on social cognitions was collected as part of a cluster-randomized controlled trial from 1166 students (59% female, mage = 18.7 years, range: 16-49) in six vocational schools before, post-intervention, and 14 months post-baseline. Data were analyzed using mixed between-within repeated measures ANOVA. We found greater improvements in intention (F(1, 833) = 9.69; η2p = 0.01; p = .018) and descriptive norms (F(1, 831) = 13.25; η2p = 0.016; p < .001) in the intervention than control arm, but these effects depended on the included control variables. Generally, intervention effects leveled off from post-intervention to follow-up. The Let's Move It intervention for SB reduction showed modest, short-lived effects on social cognitions, indicating that changes in behavior are likely due to other factors like changes to the classroom environment. Optimally, SB reduction interventions should not only change behavior but produce robust changes in conscious intentions to restrict one's sitting, so that positive effects generalize to other contexts.

A Reflection on the Tensions of Acting in Dual Roles of Doctoral Researcher and Practitioner when Evaluating a Lifestyle Intervention for Breast Cancer Patients.

This reflection was completed as part of a doctoral project to develop and trial a lifestyle intervention for people following the completion of their treatment for breast cancer. In this study the graduate student acted in the dual roles of nutrition practitioner and researcher. This article uses the experience, reflection, action (ERA) cycle of reflection to consider some of the tensions faced due to the divergent priorities and requirements of these two roles. One challenge occurred during study recruitment when a few potential participants did not meet the inclusion criteria for the study but still wished to attend the intervention sessions. It was also a challenge to mitigate the risks of distress of potentially vulnerable participants during group intervention sessions. In both instances there was a potential conflict between the needs of patients and research requirements. This reflection concluded that the obligations of both roles should be adhered to where possible, but if in doubt, the needs of the participants were paramount.

Innovative participatory evaluation methodologies to assess and sustain multilevel impacts of two community-based physical activity programs for women in Colombia.

BACKGROUND: Community-based physical activity (PA) programs are appealing to women in Latin America and show potential for improving women's health. This study aimed to engage healthy middle-aged women, breast cancer survivors and local stakeholders participating in two publicly funded community-based PA programs in Bogotá, Colombia (Recreovía and My Body) to assess and visually map the perceived barriers, facilitators, and outcomes to promote programs' improvement, scaling and sustainability. METHODS: We used two participatory action research methods, the 1) Our Voice citizen science method to capture data and drive local change in built and social environmental facilitators and barriers that influence women's engagement in community-based PA; and 2) Ripple Effects Mapping to visually map the intended and unintended outcomes of PA programs. We used thematic analysis to classify the results at the individual, social, and community levels. RESULTS: The stakeholders engaged in the participatory evaluation included cross-sector actors from the programs (N = 6) and program users (total N = 34) from the two programs (Recreovía N = 16; My Body N = 18). Program users were women with a mean age of 55.7 years (SD = 8.03), 65% lived in low-income neighborhoods. They identified infrastructure as the main feature affecting PA, having both positive (e.g., appropriate facilities) and negative (e.g., poorly built areas for PA) effects. Regarding program improvements, stakeholders advocated for parks' cleaning, safety, and appropriate use. The most highlighted outcomes were the expansion and strengthening of social bonds and the engagement in collective wellbeing, which leveraged some participants' leadership skills for PA promotion strategies in their community. The facilitated dialogue among program users and stakeholders fostered the sustainability and expansion of the community-based PA programs, even during the COVID-19 pandemic. CONCLUSIONS: The implementation of both participatory methodologies provided a multidimensional understanding of the programs' impacts and multisectoral dialogues that fostered efforts to sustain the community-based PA programs.

Evaluation of a guidelines implementation intervention to reduce work disability and sick leaves related to chronic musculoskeletal pain: a theory-informed qualitative study in occupational health care.

BACKGROUND: Guidelines for pain management and sick leave prescription were formulated and implemented in an occupational health services (OHS) in Finland to reduce work disability and sick leaves related to musculoskeletal pain. We investigated how the guidelines implementation intervention may have produced its effects, how the number of prescribed sick leave days varied before and after the launch of the guidelines, and which factors beyond physician behaviour were seen to influence sick leaves. METHODS: Seventeen physicians, two occupational physiotherapists and one occupational health care nurse were interviewed. Qualitative content analysis using both inductive and deductive approaches was performed, informed by Behaviour Change Wheel and Theoretical Domains Framework. Employees' sick leave days related to musculoskeletal disorders in 2015-2019 were drawn from the employer's register. RESULTS: Physicians' guidelines adherence was facilitated by psychological capability (e.g., having relevant knowledge, remembering to engage in recommended behaviours), reflective motivation (e.g., guidelines-related behaviours regarded as central part of one's professional role; beliefs in the positive consequences of recommended behaviours to employees and employers), and physical and social opportunities (e.g., adequate physical resources, culture of social support). Some physicians also described barriers to recommended behaviours (e.g., lack of knowledge or non-pharmacological pain treatment tools). The guidelines had served as sources of new knowledge, reminders of recommended practices and means of self-assessment. Considerable declining trend of prescribed sick leave days was detected, especially during the first years after the intervention, levelling off somewhat thereafter. OHS policies and structures were seen to enable professionals' focusing on preventing pain-related disability and prolonged sick leaves. The decline of sickness absences was also attributed to the municipal client organization's commitment and the employees' positive attitudes towards the alternatives to full-time sick leave. CONCLUSIONS: The guidelines implementation intervention was found successful. The study showed the importance of social and organizational environment supporting physicians' engagement in recommended practices.

The Barriers and Facilitators of eHealth-Based Lifestyle Intervention Programs for People With a Low Socioeconomic Status: Scoping Review.

BACKGROUND: Promoting health behaviors and preventing chronic diseases through a healthy lifestyle among those with a low socioeconomic status (SES) remain major challenges. eHealth interventions are a promising approach to change unhealthy behaviors in this target group. OBJECTIVE: This review aims to identify key components, barriers, and facilitators in the development, reach, use, evaluation, and implementation of eHealth lifestyle interventions for people with a low SES. This review provides an overview for researchers and eHealth developers, and can assist in the development of eHealth interventions for people with a low SES. METHODS: We performed a scoping review based on Arksey and O'Malley's framework. A systematic search was conducted on PubMed, MEDLINE (Ovid), Embase, Web of Science, and the Cochrane Library, using terms related to a combination of the following key constructs: eHealth, lifestyle, low SES, development, reach, use, evaluation, and implementation. There were no restrictions on the date of publication for articles retrieved upon searching the databases. RESULTS: The search identified 1323 studies, of which 42 met our inclusion criteria. An update of the search led to the inclusion of 17 additional studies. eHealth lifestyle interventions for people with a low SES were often delivered via internet-based methods (eg, websites, email, Facebook, and smartphone apps) and offline methods, such as texting. A minority of the interventions combined eHealth lifestyle interventions with face-to-face or telephone coaching, or wearables (blended care). We identified the use of different behavioral components (eg, social support) and technological components (eg, multimedia) in eHealth lifestyle interventions. Facilitators in the development included iterative design, working with different disciplines, and resonating intervention content with users. Facilitators for intervention reach were use of a personal approach and social network, reminders, and self-monitoring. Nevertheless, barriers, such as technological challenges for developers and limited financial resources, may hinder intervention development. Furthermore, passive recruitment was a barrier to intervention reach. Technical difficulties and the use of self-monitoring devices were common barriers for users of eHealth interventions. Only limited data on barriers and facilitators for intervention implementation and evaluation were available. CONCLUSIONS: While we found large variations among studies regarding key intervention components, and barriers and facilitators, certain factors may be beneficial in building and using eHealth interventions and reaching people with a low SES. Barriers and facilitators offer promising elements that eHealth developers can use as a toolbox to connect eHealth with low SES individuals. Our findings suggest that one-size-fits-all eHealth interventions may be less suitable for people with a low SES. Future research should investigate how to customize eHealth lifestyle interventions to meet the needs of different low SES groups, and should identify the components that enhance their reach, use, and effectiveness.

A Hybrid Evaluation-Optimization Trial to Evaluate an Intervention Targeting the Intersection of Alcohol and Sex in College Students and Simultaneously Test an Additional Component Aimed at Preventing Sexual Violence.

BACKGROUND: Using the multiphase optimization strategy (MOST), we previously developed and optimized an online behavioral intervention, itMatters, aimed at reducing the risk of sexually transmitted infections (STI) among first-year college students by targeting the intersection of alcohol use and sexual behaviors. PURPOSE: We had two goals: (a) to evaluate the optimized itMatters intervention and (b) to determine whether the candidate sexual violence prevention (SVP) component (included at the request of participating universities) had a detectable effect and therefore should be added to create a new version of itMatters. We also describe the hybrid evaluation-optimization trial we conducted to accomplish these two goals in a single experiment. METHODS: First year college students (N = 3,098) at four universities in the USA were individually randomized in a hybrid evaluation-optimization 2 × 2 factorial trial. Data were analyzed using regression models, with pre-test outcome variables included as covariates in the models. Analyses were conducted separately with (a) immediate post-test scores and (b) 60-day follow-up scores as outcome variables. RESULTS: Experimental results indicated a significant effect of itMatters on targeted proximal outcomes (norms) and on one distal behavioral outcome (binge drinking). There were no significant effects on other behavioral outcomes, including the intersection of alcohol and sexual behaviors. In addition, there were mixed results (positive short-term effect; no effect at 60-day follow-up) of the SVP component on targeted proximal outcomes (students' self-efficacy to reduce/prevent sexual violence and perceived effectiveness of protective behavioral strategies). CONCLUSIONS: The hybrid evaluation-optimization trial enabled us to evaluate the individual and combined effectiveness of the optimized itMatters intervention and the SVP component in a single experiment, conserving resources and providing greatly improved efficiency. TRIAL REGISTRATION: NCT04095065.

Do Combinations of Behavior Change Techniques That Occur Frequently in Interventions Reflect Underlying Theory?

BACKGROUND: Behavioral interventions typically include multiple behavior change techniques (BCTs). The theory informing the selection of BCTs for an intervention may be stated explicitly or remain unreported, thus impeding the identification of links between theory and behavior change outcomes. PURPOSE: This study aimed to identify groups of BCTs commonly occurring together in behavior change interventions and examine whether behavior change theories underlying these groups could be identified. METHODS: The study involved three phases: (a) a factor analysis to identify groups of co-occurring BCTs from 277 behavior change intervention reports; (b) examining expert consensus (n = 25) about links between BCT groups and behavioral theories; (c) a comparison of the expert-linked theories with theories explicitly mentioned by authors of the 277 intervention reports. RESULTS: Five groups of co-occurring BCTs (range: 3-13 BCTs per group) were identified through factor analysis. Experts agreed on five links (≥80% of experts), comprising three BCT groups and five behavior change theories. Four of the five BCT group-theory links agreed by experts were also stated by study authors in intervention reports using similar groups of BCTs. CONCLUSIONS: It is possible to identify groups of BCTs frequently used together in interventions. Experts made shared inferences about behavior change theory underlying these BCT groups, suggesting that it may be possible to propose a theoretical basis for interventions where authors do not explicitly put forward a theory. These results advance our understanding of theory use in multicomponent interventions and build the evidence base for further understanding theory-based intervention development and evaluation.

Addressing sickness absence among adolescents and young adults: an evaluation of the Medical Advice for Sick-reported Students intervention.

BACKGROUND: Sickness absence is associated with lower school achievements and early school leaving. The Medical Advice for Sick-reported Students (MASS) intervention is a proactive school-based intervention focused primarily on early identification and reduction of sickness absence. This study used a program evaluation framework to evaluate the MASS intervention among intermediate vocational education students and Youth Health Care professionals. Outcome indicators were primarily number of sick days, education fit, and school performance, and secondarily, seven health indicators. Process indicators were dose delivered and received, satisfaction, and experience. METHODS: The MASS intervention evaluation was conducted in ten intermediate vocational education schools. Students with extensive sickness absence from school in the past three months were included in either the intervention or control condition. Students completed a baseline and a six-month follow-up self-report questionnaire. Linear and logistic regression analyses were applied. Students and Youth Health Care professionals completed an evaluation form regarding their satisfaction and experience with the intervention. RESULTS: Participants (n = 200) had a mean age of 18.6 years (SD = 2.02) and 78.5% were female. The MASS intervention showed positive results on decreasing sickness absence in days (ß = -1.13, 95% CI = -2.22;-0.05, p < 0.05) and on decreasing depressive symptoms (ß = -4.11, 95% CI = -7.06;-1.17, p < 0.05). No effects were found for other health indicators (p > 0.05). A significant interaction revealed a decline in sickness absence in males (p < 0.05) but not in females (p > 0.05). Youth Health Care professionals found the application of the MASS intervention useful (n = 35 forms). The mean rating of students for the consultation within the MASS intervention was an 8.3 (SD = 1.3) out of 10 (n = 14 forms). CONCLUSIONS: Our study provides some indication that the MASS intervention has positive effects on decreasing both sickness absence and depressive symptoms among intermediate vocational education students. The Youth Health Care professionals who provided the consultation as part of the MASS intervention considered the intervention to be useful and stated that the consultation was delivered as intended in almost all cases. Students were generally satisfied with the intervention. We recommend that future research evaluates the MASS intervention in a large randomized controlled trial with a longer follow-up. TRIAL REGISTRATION: This study was prospectively registered in the Netherlands Trial Register under number NTR5556 , in October 2015.

Evaluating the feasibility of a nurse-led self-management support intervention for kidney transplant recipients: a pilot study.

BACKGROUND: To support effective self-management after kidney transplantation, a holistic nurse-led self-management support intervention was developed using the Intervention Mapping approach. The primary aim was to evaluate the feasibility, acceptability and fidelity of the intervention for kidney transplant recipients and professionals. The secondary aim was to explore preliminary effects on outcomes. METHODS: A pilot study was conducted in 2015-2017 to evaluate the intervention. Nurse Practitioners (NP) guided recipients in assessing 14 life areas using the Self-Management Web. Participants were supported in developing self-regulation skills which can be applied to self-management of the illness. Strategies included goal setting, action planning, and promotion of motivation and self-efficacy. Adult recipients from an outpatient clinic of a Dutch University Hospital who underwent their transplant at least 1 month ago, were invited to participate. NPs, nephrologists and recipients were interviewed to assess feasibility, fidelity and implementation experience. Consultations were videoed and analysed to assess fidelity. To assess the preliminary effects, the intervention group completed baseline (T0) and follow-up (T1) questionnaires on self-management behavior, self-efficacy, quality of life and quality of care. A historical control group of kidney transplant recipients completed the same questionnaires at T1. RESULTS: Twenty-seven recipients agreed to participate in the intervention group, of which 24 completed the intervention and 16 completed baseline and follow-up surveys. The control group consisted of 33 recipients. Professionals and recipients appraised the open, holistic focus of the intervention as a welcome addition to standard care and felt that this helped to build a relationship of trust. Recipients also felt they became more competent in problem-solving skills. The within-group analysis showed no significant increase in patients' self-management skills. The between-groups analysis showed significantly higher medication adherence among the intervention group (P = 0.03; G = 0.81). The within-groups analysis showed a significantly higher perceived quality of care (P = 0.02) in the intervention group. CONCLUSION: This holistic nurse-led self-management support intervention was found to be feasible and acceptable by professionals and recipients alike. This pilot had a small sample therefore further research is needed into the potential effects on self-management behavior and well-being of transplant recipients.

Evaluating Complex Health Interventions With Randomized Controlled Trials: How Do We Improve the Use of Qualitative Methods?

Qualitative methods are underutilized in health intervention evaluation, and overshadowed by the importance placed on randomized controlled trials (RCTs). This Commentary describes how innovative qualitative methods are being used as part of RCTs, drawing on articles included in a special issue of Qualitative Health Research on this topic. The articles' insights and a review of innovative qualitative methods described in trial protocols highlights a lack of attention to structural inequalities as a causal mechanism for understanding human behavior. We situate this gap within some well-known constraints of RCT methodologies, and a discussion of alternative RCT approaches that hold promise for bringing qualitative methods center stage in intervention evaluation, including adaptive designs, pragmatic trials, and realist RCTs. To address the power hierarchies of health evaluation research, however, we argue that a fundamental shift needs to take place away from a focus on RCTs and toward studies of health interventions.

Adaptation of a mental development assessment tool for the evaluation of the long-term effect of a successful nutrition intervention in Ghana.

This study adapted a cognitive assessment tool to be used in evaluating nutrition interventions in developing countries and assessed its reliability and validity in Ghana. The tool was used to evaluate the long-term effect of the Enhancing Child Nutrition through Animal Source Food Management (ENAM) project. The former ENAM participants' children were contacted (now 13 to 15 years old). The items in the Wechsler Abbreviated Scale of Intelligence-II were adapted, pretested, refined, and pretested again. Cross-sectional data collection was conducted with former ENAM participants (60 interventions and 51 comparison families) in one of ENAM's three sites (the Guinea Savanna zone). Data on participants' socio-economic status and food insecurity were collected, along with their children's intellectual functioning, dietary intake, school attainment, anthropometry, and symptoms of depression. Alpha coefficient of the verbal subscale improved between the first and second pretest (from .34 to .80). After controlling for age, the intelligence scores of the children were associated with their grade (r = .35, p = .001) and academic performance (r = .26 to .33, p < .05). The verbal scale was associated with their anthropometry (r = .24 to .27, p < .05). The intervention children still recorded a better dietary diversity score than controls (6.8 vs 5.8, p = .0001); however, significance was lost after adjusting for confounders. There were no significant group differences in growth or intellectual functioning. The adapted Wechsler Abbreviated Scale of Intelligence-II tool performed well in evaluating adolescent intellectual functioning in rural Ghana, and there were no long-term effects of ENAM intervention on child growth and development.

[Evaluation of long-term adverse cardiovascular events risk after elective percutaneous coronary intervention].

OBJECTIVE: The aim of our study was to analyze long-term outcomes, to identify their predictors and to develop a model for determining the risk of long-term adverse сardiovascular events after elective percutaneous coronary interventions (PCI). MATERIALS AND METHODS: A retrospective study included 151 patients 6 years after the elective PCI. Outcomes were assessed by analyzing medical records and telephone interviews. The primary composite end point of the study was a major adverse cardiovascular event (MACCE), including death from cardiovascular causes, acute coronary syndrome, acute cerebrovascular accident. RESULTS: Death from cardiovascular events was reported in 10.6 % of patients, acute coronary syndrome occurred in 34.4 %, stroke - in 6.6 %. Thus MAСCE occurred in 40.4 % of patients. MACCE predictors in the long-term period were chronic kidney disease, contrast-induced acute kidney injury, baseline C-reactive protein more than 5.5 mg/l. Restenosis of previously installed stents increases the risk of MACCE at 8.09 times, chronic obstructive pulmonary disease - 3.4 times PT - 2.84 times, family history for cardiovascular disease (CVD) - in 2.94 times, a very high risk of contrast-induced nephropathy (CIN) (≥11 points on the R. Mehran scale) - 2.15 times. The most significant MACCE's predictors identified using stepwise logistic regression and included in the developed model are: family history for СVD, statins reception during the procedure of PCI, the initial level of postprandial blood glucose, high risk of CIN (11-15 points on a scale of R. Mehran). AUC values for the found model was 0.852 [95 % CI 0.749-0.956]. CONCLUSION: The use of our model of risk stratification in patients after elective PCI allows, on the basis of simple clinical characteristics, to distinguish groups of patients with a high residual risk of adverse cardiovascular events that require the timely application of more active follow-up strategies.

An Appraisal of Social Network Theory and Analysis as Applied to Public Health: Challenges and Opportunities.

The use of social network theory and analysis methods as applied to public health has expanded greatly in the past decade, yielding a significant academic literature that spans almost every conceivable health issue. This review identifies several important theoretical challenges that confront the field but also provides opportunities for new research. These challenges include (a) measuring network influences, (b) identifying appropriate influence mechanisms, (c) the impact of social media and computerized communications, (d) the role of networks in evaluating public health interventions, and (e) ethics. Next steps for the field are outlined and the need for funding is emphasized. Recently developed network analysis techniques, technological innovations in communication, and changes in theoretical perspectives to include a focus on social and environmental behavioral influences have created opportunities for new theory and ever broader application of social networks to public health topics.

'Emotiplay': a serious game for learning about emotions in children with autism: results of a cross-cultural evaluation.

Children with autism spectrum conditions (ASC) experience difficulties recognizing others' emotions and mental states. It has been shown that serious games (SG) can produce simplified versions of the socio-emotional world. The current study performed a cross-cultural evaluation (in the UK, Israel and Sweden) of Emotiplay's SG, a system aimed to teach emotion recognition (ER) to children with ASC in an entertaining, and intrinsically motivating way. Participants were 6-9 year olds with high functioning ASC who used the SG for 8-12 weeks. Measures included face, voice, body, and integrative ER tasks, as well as parent-reported level of autism symptoms, and adaptive socialization. In the UK, 15 children were tested before and after using the SG. In Israel (n = 38) and Sweden (n = 36), children were randomized into a SG or a waiting list control group. In the UK, results revealed that 8 weeks of SG use significantly improved participants' performance on ER body language and integrative tasks. Parents also reported their children improved their adaptive socialization. In Israel and Sweden, participants using the SG improved significantly more than controls on all ER measures. In addition, parents in the Israeli SG group reported their children showed reduced autism symptoms after using the SG. In conclusion, Emotiplay's SG is an effective and motivating psycho-educational intervention, cross-culturally teaching ER from faces, voices, body language, and their integration in context to children with high functioning ASC. Local evidence was found for more generalized gains to socialization and reduced autism symptoms.

Reduction of excavation face collapse risk in tunnelling.

Two large road tunnels, recently developed near Florence, showed instabilities of the excavation face which subsequently caused sixteen collapses. Due to the risk for workers' safety, the public authority for occupational health and safety (ASL) has monitored the failure rate and other background variables in order to assess the possible correlations between risk reductions, its own actions, and those of the various safety actors involved. OBJECTIVES: To evaluate if the interventions carried out by the design team were able to reduce the risks of collapse and which of the ASL actions and/or which other factors were more effective in changing the attitudes of the parties involved, leading to a more expensive but safer project variant. RESULTS: After adoption of the second of two project variants, no more collapses were observed. No correlation was found between trend of ASL inspections and observed variation of collapse rate. Conversely, the adoption of strongly coercive measures and investigation reporting by local media coincided with periods of risk reduction, even if the low number of events does not allow for statistical evaluation. CONCLUSIONS: These findings appear to be coherent with the ratio of the cost of penalties related to health and safety infringements (thousands of euros) to the overall cost of the safer project variant (a hundred times greater).  The safer variant required 7% more labour but avoided forced interruptions caused by the collapses, allowing a 13% faster excavation rate.
