The Delivery of Person-Centered Care for People Living With Dementia in Residential Aged Care: A Systematic Review and Meta-Analysis

BACKGROUND AND OBJECTIVES

Person-centered care is the gold standard of care for people living with dementia, yet few systematic reviews have detailed how it is delivered in practice. This mixed-methods review aimed to examine the delivery of person-centered care, and its effectiveness, for people living with dementia in residential aged care.

RESEARCH DESIGN AND METHODS

A systematic review and meta-analysis. Eligible studies were identified across 4 databases. Quantitative and qualitative studies containing data on person-centered care delivered to people with dementia living in residential aged care were included. Meta-analysis using a random-effects model was conducted where more than 3 studies measured the same outcome. A narrative meta-synthesis approach was undertaken to categorize verbatim participant quotes into representative themes. Risk of bias was undertaken using quality appraisal tools from the Joanna Briggs Institute.

RESULTS

41 studies were identified for inclusion. There were 34 person-centered care initiatives delivered, targeting 14 person-centered care outcomes. 3 outcomes could be pooled. Meta-analyses demonstrated no reduction in agitation (standardized mean difference -0.27, 95% confidence interval [CI], -0.58, 0.03), improvement in quality of life (standardized mean difference -0.63, 95% CI: -1.95, 0.70), or reduced neuropsychiatric symptoms (mean difference -1.06, 95% CI: -2.16, 0.05). Narrative meta-synthesis revealed barriers (e.g., time constraints) and enablers (e.g., staff collaboration) to providing person-centered care from a staff perspective.

DISCUSSION AND IMPLICATIONS

The effectiveness of person-centered care initiatives delivered to people with dementia in residential aged care is conflicting. Further high-quality research over an extended time is required to identify how person-centered care can be best implemented to improve resident outcomes.

Effectiveness of a hand hygiene training intervention in improving knowledge and compliance rate among healthcare workers in a respiratory disease hospital

Background

Practicing hand hygiene (HH) is a crucial element of infection control, with healthcare workers (HCWs) playing a vital role in preventing the spread of infection. However, inadequate knowledge and non-compliance to HH protocols pose significant challenges in healthcare settings. This study aimed to evaluate the effectiveness of an HH training intervention in enhancing knowledge and staff compliance within a respiratory disease hospital.

Method

A pre-and post-training study was conducted among the healthcare workers in a respiratory disease treatment facility. The intervention comprised a series of 3-hour training sessions conducted over five days, focusing on the World Health Organization's (WHO) recommended guideline "Your Five Moments For Hand Hygiene." These sessions covered proper HH techniques and underscored the repercussions of inadequate compliance. Educational materials related to HH were displayed in prominent locations throughout the facility. The knowledge levels and compliance rate were assessed before and after the intervention.

Result

The intervention significantly improved HH knowledge levels and compliance rates among the participants. Marking a significant improvement, the compliance rate of HH protocols increased from 66.0% to 88.3% during the pre-to post-training period, with a concurrent increase in the mean knowledge score from 68.6% to 78.9%.

Conclusion

This study underscores the potential of training and education in elevating HH compliance and knowledge among healthcare workers. The findings advocate that healthcare facilities routinely incorporate such interventions into their infection control programs, ultimately improving patient and healthcare worker safety.

Use of behavior change techniques in physical activity programs and services for older adults: findings from a rapid review

BACKGROUND

Understanding behavior change techniques (BCTs) used in randomized controlled trials (RCTs) of physical activity programs/services for older adults can help us to guide their implementation in real-world settings.

PURPOSE

This study aims to: (a) identify the number and type of BCTs used in physical activity programs/services for older adults evaluated in large, good quality RCTs and (b) explore the impact of different BCTs on different outcome domains.

METHODS

This is a secondary data analysis of a WHO-commissioned rapid review of physical activity programs/services for older adults. Fifty-six trials testing 70 interventions were coded for the type and number of BCTs present using a published BCT taxonomy. The proportion of positive effects found from physical activity interventions using the most common BCTs was calculated for the outcomes of physical activity, intrinsic capacity, functional ability, social domain, cognitive and emotional functioning, and well-being and quality of life.

RESULTS

Thirty-nine of the 93 possible BCTs were identified in the included trials and 529 BCTs in total (mean 7.6, range 2-17). The most common BCTs were "action planning" (68/70 interventions), "instructions on how to perform a behavior" (60/70), "graded tasks" (53/70), "demonstration of behavior" (44/70), and "behavioral practice/rehearsal" (43/70). Interventions that used any of the most common BCTs showed overwhelmingly positive impacts on physical activity and social domain outcomes.

CONCLUSION

Consideration of which BCTs are included in interventions and their impact on outcomes can improve the effectiveness and implementation of future interventions. To enable this, providers can design, implement, and evaluate interventions using a BCT taxonomy.

One research question, two meta-analyses, three conclusions: Commentary on "A systematic review with meta-analysis of Cognitive Bias Modification interventions for anger and aggression"

Recently two independent meta-analyses on the efficacy of Cognitive Bias Modification of Interpretation (CBM-I) to reduce aggressive behavior came to different conclusions: Ciesinski et al. (2023) concluded that "CBM demonstrates efficacy for the treatment of aggressive behavior" (Abstract), whereas our research team concluded that "findings show limited support for the efficacy of CBM-I to reduce aggressive behavior" (AlMoghrabi et al., 2023, Discussion). How can similar meta-analyses reach such different conclusions? In this commentary, we raise awareness concerning how 1) seemingly identical research questions can be based on meaningfully different definitions of the intervention and outcomes; 2) intervention efficacy conclusions can depend on outcome assessment type; and 3) the interpretation of underpowered moderator analyses should not depend on statistical significance. We end our commentary with a third, more nuanced conclusion that can reconcile the two disparate conclusions: that current CBM-I is an effective experimental manipulation to modify interpretation biases, but not an effective stand-alone treatment to reduce aggressive behavior.

Development and evaluation of a concise nurse-driven non-pharmacological delirium reduction workflow for hospitalized patients: An interrupted time series study

We created a concise nurse-driven delirium reduction workflow with the aim of reducing delirium rates and length of stay for hospitalized adults. Our nurse-driven workflow included five evidence-based daytime "sunrise" interventions (patient room lights on, blinds up, mobilization/out-of-bed, water within patient's reach and patient awake) and five nighttime "turndown" interventions (patient room lights off, blinds down, television off, noise reduction and pre-set bedtime). Interventions were also chosen because fidelity could be quickly monitored twice daily without patient interruption from outside the room. To evaluate the workflow, we used an interrupted time series study design between 06/01/17 and 05/30/22 to determine if the workflow significantly reduced the unit's delirium rate and average length of stay. Our workflow is feasible to implement and monitor and initially significantly reduced delirium rates but not length of stay. However, the reduction in delirium rates were not sustained following the emergence of the COVID-19 pandemic.

Evaluating the efficacy of auricular acupuncture for chemotherapy-induced taste alterations: A pilot randomized controlled trial

PURPOSE

Irrespective of the development of acupuncture-based interventions, clinical evidence regarding their efficacy remains controversial owing to issues with the study design and an unclear risk of bias. This study aimed to evaluate the efficacy of auricular acupuncture in managing taste alterations in patients with cancer undergoing platinum-based chemotherapy.

METHODS

We conducted a pilot randomized controlled trial involving 73 patients randomly assigned to an auricular acupuncture or a control group. The primary outcome was the severity of chemotherapy-induced taste alterations, and the secondary outcomes included quality of life and negative emotions of the patients.

RESULTS

A total of 49 participants completed the study. Compared to the control group, patients in the auricular acupuncture group showed significant reductions in discomfort, general taste alterations, and total scores on the Chemotherapy-induced Taste Alteration Scale (all p < 0.05). Furthermore, we observed significant improvements in quality of life, including physical function (p = 0.007), role function (p = 0.006), emotional function (p = 0.016), nausea and vomiting (p = 0.021), appetite loss (p = 0.046), and significant improvements in anxiety and depression (p < 0.01).

CONCLUSIONS

Our findings suggest that auricular acupuncture may be a beneficial intervention for managing chemotherapy-induced taste alterations in patients with cancer receiving platinum-based chemotherapy. It may also contribute to improvements in quality of life and negative emotions. However, these results are preliminary, and further evaluation with larger randomized controlled trials is necessary.

Interventions to reduce falls in community-dwelling adults with intellectual disability: a systematic review

BACKGROUND

People with intellectual disability have a high risk of falls and falls-related injuries. Although people with intellectual disability are at increased risk of falls, there is a need to better understand the efficacy of interventions that can help reduce falls and address risk factors in this population. This systematic review aimed to evaluate the type, nature and effectiveness of interventions undertaken to reduce falls with community-dwelling adults with intellectual disability and the quality of this evidence.

METHOD

Four electronic databases were searched: Ovid MEDLINE, PsycINFO, CINAHL Plus and the Cochrane Library. Studies were included if they involved people aged 18 years or over, at least 50% of study participants had intellectual disability, participants were community-dwelling, and the study evaluated any interventions aiming to reduce falls. Study quality was assessed using the National Institutes of Health study quality assessment tools. Reporting of the review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

RESULTS

Seven studies were eligible for review, with a total of 286 participants and mean age of 50.4 years. As only one randomised trial was identified, a narrative synthesis of results was undertaken. Five studies evaluated exercise interventions, one evaluated a falls clinic programme, and one evaluated stretch fabric splinting garments. Methodological quality varied (two studies rated as good, four as fair, and one as poor). Exercise interventions varied in terms of exercise type and dosage, frequency and intensity, and most did not align with recommendations for successful falls prevention exercise interventions reported for older people. While the majority of studies reported reduced falls, they differed in methods of reporting falls, and most did not utilise statistical analyses to evaluate outcomes.

CONCLUSION

This review identified a small number of falls prevention intervention studies for people with intellectual disability. Although several studies reported improvements in fall outcomes, ability to draw conclusions about intervention effectiveness is limited by small sample sizes and few studies. Further large-scale research is required to implement and evaluate falls prevention interventions specifically for adults with intellectual disability.

Recruitment and retention challenges and strategies in randomized controlled trials of psychosocial interventions for children with cancer and their parents: a collective case study

In pediatric oncology there are few examples of successful recruitment and retention strategies in psychosocial care research. This study aims to summarize experiences, challenges, and strategies for conducting randomized controlled trials (RCTs) of psychosocial intervention studies among children with cancer and their parent(s). We conducted a collective case study. To identify the cases, Pubmed and two trial registries were searched for ongoing and finished RCTs of psychosocial intervention studies for children with cancer and their parents. Online semi-structured expert interviews discussing recruitment and retention challenges and strategies were performed with principal investigators and research staff members of the identified cases. Nine studies were identified. Investigators and staff from seven studies participated, highlighting challenges and strategies within three major themes: eligibility, enrollment and retention. Regarding eligibility, collaborating constructively with healthcare professionals and involving them before the start of the study were essential. Being flexible, training the research staff, enabling alignment with the participants' situation, and providing consistency in contact between the research staff member and the families were important strategies for optimizing enrollment and retention. All studies followed a stepped process in recruitment.  Conclusion: Although recruitment and retention in some selected studies were successful, there is a paucity of evidence on experienced recruitment and retention challenges in pediatric psychosocial research and best practices on optimizing them. The strategies outlined in this study can help researchers optimize their protocol and trial-implementation, and contribute to better psychosocial care for children with cancer and their parents.  Trial Registration: This study is not a clinical trial. What is Known: • Performing RCTs is challenging, particularly in pediatric psychosocial research when both the child and parent are targeted. Recruitment and retention are common concerns. In pediatric oncology, there are few examples of successful recruitment and retention strategies in psychosocial care research. What is New: • Key strategies to collaborate constructively with healthcare professionals were outlined. Being flexible, training the research staff, alignment with the participant's situations and providing consistency in contact between the research staff member and the families were considered as essential strategies.

Effects of Therapeutic Intervention on Spatiotemporal Gait Parameters in Adults With Neurologic Disorder: Systematic Review and Meta-analysis

OBJECTIVE

This systematic review and meta-analysis aimed to review and quantify the changes in gait parameters after therapeutic intervention in adults with neurologic disorders.

DATA SOURCES

A keyword search was performed in 4 databases: PubMed, CINAHL, Scopus, and Web of Science (01/2000-12/2021). We performed the search algorithm including all possible combinations of keywords. Full-text articles were examined further using forward/backward search methods.

STUDY SELECTION

Studies were thoroughly screened using the following inclusion criteria: Study design: randomized controlled trial; adults ≥55 years old with a neurologic disorder; therapeutic intervention; spatiotemporal gait characteristics; and language: English.

DATA EXTRACTION

A standardized data extraction form was used to collect the following methodological outcome variables from each of the included studies: author, year, population, age, sample size, and spatiotemporal gait parameters such as cadence, step length, step width, or double limb support. A meta-analysis was performed among trials presenting with similar characteristics, including study population and outcome measure. If heterogeneity was >50%, a random plot analysis was used; otherwise, a fixed plot analysis was done.

DATA SYNTHESIS

We included 25 out of 34 studies in our meta-analysis that examined gait in adults with neurologic disorders. All analyses used effect sizes and standard error and a P<.05(denoted by *) threshold was considered statistically significant. Overall, we found that sensory (SS) and electrical stimulation (ES) had the most significant effect on step length (SS: z=5.44*, ES: z=2.42*) and gait speed (SS: z=6.19*, ES: z=7.38*) in adults with Parkinson disease (PD). Although balance or physical activity interventions were not found to be effective in modifying step length in adults with PD, they showed a significant effect on gait speed. Further, physical activity had the most significant effect on cadence in adults with PD (z=2.84*) relative to sensory stimulation effect on cadence (z=2.59*). For stroke, conventional physical therapy had the most significant effect on step length (z=3.12*) and cadence (z=3.57*).

CONCLUSION

Sensory stimulation such as auditory and somatosensory stimulation while walking had the most significant effect on step length in adults with PD. We also found that conventional physical therapy did improve spatial gait parameters relative to other physical activity interventions in adults with PD and stroke.

Non-pharmacological interventions for self-management of fatigue in adults: An umbrella review of potential interventions to support patients recovering from critical illness

PURPOSE

Fatigue is a common symptom after critical illness. However, evidence-based interventions for fatigue after critical illness are lacking. We aimed to identify interventions to support self-management of fatigue caused by physical conditions and assess their effectiveness and suitability for adaptation for those with fatigue after critical illness.

MATERIALS AND METHODS

We conducted an umbrella review of systematic reviews. Databases included CINAHL, PubMed, Medline, PsycINFO, British Nursing Index (BNI), Web of Science, Cochrane Database of Systematic Reviews (CDSR), JBI Evidence Synthesis Database, and PROSPERO register. Included reviews were appraised using the JBI Checklist for Systematic Reviews and Research Syntheses. Results were summarised narratively.

RESULTS

Of the 672 abstracts identified, 10 met the inclusion criteria. Reviews focused on cancer (n = 8), post-viral fatigue (n = 1), and Systemic Lupus Erythematosus (SLE) (n = 1). Primary studies often did not address core elements of self-management. Positive outcomes were reported across all reviews, and interventions involving facilitator support appeared to be most effective.

CONCLUSIONS

Self-management can be effective at reducing fatigue symptoms and improving quality of life for physical conditions and has clear potential for supporting people with fatigue after critical illness, but more conclusive data on effectiveness and clearer definitions of self-management are required.

Effect of distinct psychological interventions on changes in self-reported distress, depression and loneliness among older adults during COVID-19

BACKGROUND

Older adults have been considered a primary at-risk population during the coronavirus disease 2019 (COVID-19) pandemic, and many efforts have been and still are directed toward supporting them and enhancing their capacity to cope with the pandemic. Evidence shows that by enhancing proactive coping abilities through psychological interventions, in which cognitive-behavioral and mindfulness techniques are taught and practiced effectively, these interventions have supported older adults throughout the pandemic. However, the underlying mechanisms by which specific intervention components affect various mental states such as distress, depression and loneliness among older adults remain unclear and warrant investigation.

AIM

To determine the effect of an intervention using cognitive-behavioral and mindfulness techniques on changes in distress, depression and loneliness.

METHODS

We performed a secondary analysis on data from a previous study in which community-dwelling older adults attended a short-term, internet-based intervention during the first COVID-19 wave in Israel. The intervention included seven sessions during which various cognitive-behavioral and mindfulness techniques were learned and practiced. In-session changes in psychological distress were measured using the Subjective Units of Distress Scale (SUDS), which participants rated at the beginning and end of each session. Participants also filled out questionnaires that evaluated levels of depression [Patient Health Ques-tionnaire (PHQ-9)] and loneliness (UCLA loneliness Scale) prior to and after the entire intervention process. The effect of in-session changes in the SUDS on changes in post-intervention depression and loneliness levels were assessed, as a proxy for distinct technique effectiveness.

RESULTS

The findings indicated in-session differences in terms of a decrease in psychological distress (SUDS). Sessions that included relaxation exercises and guided imagery, as well as sessions that included cognitive restructuring and mindfulness meditation, demonstrated the largest decreases in in-session psychological distress (≥ 35%). Two multivariate regression models, one for levels of post-intervention depression (PHQ-9 score) and the other for levels of post-intervention loneliness (UCLA loneliness score), were fitted. The results revealed two statistically significant explanatory variables for depression: The SUDS difference for sessions in which cognitive restructuring and mindfulness meditation were practiced, beta = -0.25, 95%CI: -1.23 to -0.1, and the pre-intervention level of depression, beta = 0.62, 95%CI: 0.37-0.75. The second model for loneliness revealed only one significant explanatory variable: The SUDS difference for sessions in which relaxation and guided imagery were practiced, beta = 0.41, 95%CI: 0.14-0.65.

CONCLUSION

Different psychological techniques seem to have different effects on distress, loneliness and depression. Understanding the pathways by which distinct techniques affect negative mental symptoms has implications for future intervention design.

Prevention of type 2 diabetes through remotely-administered lifestyle programs: A systematic review

BACKGROUND

Although effective in reducing the risk of type 2 diabetes (T2D), in-person lifestyle modification programs have been underutilized. To minimize barriers related to convenience and accessibility, recent research has focused on developing virtual or remote interventions that may have comparable or greater efficacy in promoting lifestyle changes and reducing the risk of T2D. We conducted a systematic review to evaluate the efficacy of remotely-administered lifestyle interventions on preventing T2D.

METHODS

We searched an electronic database by using keywords, and a web-based software platform was used to screen articles and extract data in duplicate. We included articles with adolescent/adult participant populations who had prediabetes or were at elevated risk of diabetes, remotely-administered lifestyle interventions on T2D prevention, and changes in glycemic traits. We excluded trials of patients with prevalent T2D, interventions that included medications, and those not relevant to our outcomes of interest.

RESULTS

A total of 8 publications were included in this systematic review. Six papers indicated significant reductions in weight and/or glycemic biomarkers such as HbA1c and fasting glucose. All studies reported that remotely-administered interventions were convenient for participants, and one publication reported that participation of the online DPP group was significantly higher than the in-person DPP.

CONCLUSION

These findings suggest that remotely-administered lifestyle interventions for T2D prevention could be a promising participant-friendly alternative to in-person programs, with efficacy for reducing weight and glycemic biomarkers.

The professional network underlying cerebral palsy intervention research based on systematic reviews and meta-analyses published in international journals: authors' communities, institutional networks, and international collaboration

Cerebral palsy (CP) is a well-researched area of medical science, health science and special education. The growing number of publications every year makes difficult to monitor the progress of this research domain, therefore there is a broad interest for conducting systematic reviews and meta-analyses of interventions in international peer-reviewed scientific journals. Our goal is to analyze the scientific activity of authors who published systematic reviews and meta-analyses of CP intervention studies. To identify the active researchers, institutions, and countries, we used scientometric and bibliometric indicators that assess their productivity, collaborations, and the citations (utilization/usefulness of their studies), also paying attention to the institutional background and the network structure of national and international collaboration. We used Scopus to search for articles and included systematic reviews and meta-analyses of intervention studies, a total of 180 works, in our sample. Our results showed active and large communities of prolific authors and groups of authors with diverse institutional background. Most institutions are universities, hospitals, but we found various other organizations among them. Most of the universities are leading educational institutions according to international rankings; some of them are among the top-ranking ones. In geographical terms, the North American, Australian, and European regions are the most active and most interconnected ones. We assume organizations other than scientific collaboration networks also play a major role in the productivity and dissemination of scientific knowledge in this research area. As an example, we could mention the network, including the US, Australian and European registers. Authors living and working in the Far East, the Middle East or in South America also started to publish relevant articles in the 2010s. The research network structuring scientific knowledge in this area is flourishing.

Effects of exercise on symptoms of anxiety in primary care patients: A randomized controlled trial

BACKGROUND

There is a need for high-quality research regarding exercise interventions for persons with anxiety disorders. We investigate whether a 12-week exercise intervention, with different intensities, could reduce anxiety symptoms in patients with anxiety disorders.

METHODS

286 patients were recruited from primary care in Sweden. Severity of symptoms was self-assessed using the Beck Anxiety Inventory (BAI) and the Montgomery Åsberg Depression Rating Scale (MADRS-S). Participants were randomly assigned to one of two group exercise programs with cardiorespiratory and resistance training and one control/standard treatment non-exercise group, with 1:1:1 allocation.

RESULTS

Patients in both exercise groups showed larger improvements in both anxiety and depressive symptoms compared to the control group. No differences in effect sizes were found between the two groups. To study a clinically relevant improvement, BAI and MADRS-S were dichotomized with the mean change in the control group as reference. In adjusted models the odds ratio for improved symptoms of anxiety after low-intensity training was 3.62 (CI 1.34-9.76) and after moderate/high intensity 4.88 (CI 1.66-14.39), for depressive symptoms 4.96 (CI 1.81-13.6) and 4.36 (CI 1.57-12.08) respectively. There was a significant intensity trend for improvement in anxiety symptoms.

LIMITATIONS

The use of self-rating measures which bears the risk of an under- or overestimation of symptoms.

CONCLUSIONS

A 12-week group exercise program proved effective for patients with anxiety syndromes in primary care. These findings strengthen the view of physical exercise as an effective treatment and could be more frequently made available in clinical practice for persons with anxiety issues.

Preventing railway suicides through level crossing removal: a multiple-arm pre-post study design in Victoria, Australia

PURPOSE

Rail level crossing removals to improve transport performance across metropolitan Melbourne (state of Victoria) resulted in new rail fencing and grade-separation of tracks from the surrounding environment at several sites. These design changes restricted pedestrian access to the rail tracks, which is a countermeasure known to prevent railway suicide in other settings. We examined whether any such suicide prevention effect followed the removals.

METHODS

We used a multiple-arm pre-post design to test whether a decrease in monthly frequency of railway suicides occurred at level crossing removal sites (intervention sites), compared to randomly matched sites where level crossings had not yet been removed (control sites). We used data available in the Victorian Suicide Register covering the period 1st January 2008 to 30th June 2021.

RESULTS

The mean monthly number of railway suicides decreased by 68% within a 500 m radius of intervention sites (RR: 0.32; CI 95% 0.11-0.74) and by 61% within a 1000 m radius of intervention sites (RR: 0.39; CI 95% 0.21-0.68). There was no evidence that the mean monthly number of railway suicides changed at the control sites, either within a 500 m radius (RR: 0.88; CI 95% 0.47-1.56) or a 1000 m radius (RR: 0.82; CI 95% 0.52-1.26).

CONCLUSION

The reduction in railway suicides at locations where level crossings were removed, demonstrates the suicide prevention benefits that can be derived from a major infrastructure project even if not initially intended. Planning for major infrastructure projects should include consideration of these benefits, with designs incorporating features to maximise suicide prevention impact.

The use of the mannitol test as an outcome measure in asthma intervention studies: a review and practical recommendations

BACKGROUND

The mannitol test is an indirect bronchial challenge test widely used in diagnosing asthma. Response to the mannitol test correlates with the level of eosinophilic and mast cell airway inflammation, and a positive mannitol test is highly predictive of a response to anti-inflammatory treatment with inhaled corticosteroids. The response to mannitol is a physiological biomarker that may, therefore, be used to assess the response to other anti-inflammatory treatments and may be of particular interest in early phase studies that require surrogate markers to predict a clinical response. The main objectives of this review were to assess the practical aspects of using mannitol as an endpoint in clinical trials and provide the clinical researcher and respiratory physician with recommendations when designing early clinical trials.

METHODS

The aim of this review was to summarise previous uses of the mannitol test as an outcome measure in clinical intervention studies. The PubMed database was searched using a combination of MeSH and keywords. Eligible studies included intervention or repeatability studies using the standard mannitol test, at multiple timepoints, reporting the use of PD₁₅ as a measure, and published in English.

RESULTS

Of the 193 papers identified, 12 studies met the inclusion criteria and data from these are discussed in detail. Data on the mode of action, correlation with airway inflammation, its diagnostic properties, and repeatability have been summarised, and suggestions for the reporting of test results provided. Worked examples of power calculations for dimensioning study populations are presented for different types of study designs. Finally, interpretation and reporting of the change in the response to the mannitol test are discussed.

CONCLUSIONS

The mechanistic and practical features of the mannitol test make it a useful marker of disease, not only in clinical diagnoses, but also as an outcome measure in intervention trials. Measuring airway hyperresponsiveness to mannitol provides a novel and reproducible test for assessing efficacy in intervention trials, and importantly, utilises a test that links directly to underlying drivers of disease.

Outcomes of Team-Centered, Occupational Adaptation-Based Versus Traditional Dementia Workforce Training : Résultats comparés d'une formation axée sur l'équipe et l'adaptation occupationnelle et de l'approche de formation traditionnelle pour le personnel travaillant auprès des personnes atteintes de démence

Background. Dementia workforce training aligned with Occupational Adaptation (OA) theory may facilitate teams resolving challenges in the care environment more than traditional skills-based (SB) training, although comparisons are needed. Purpose. This pilot study compared effectiveness of an OA and SB program on relative mastery and team development for dementia care teams at a continuing care retirement community. Method. In a quasi-experimental study, employees underwent nine sessions in an OA or SB program. Relative Mastery Measurement Scale and Team Development Measure results were collected pre-, mid-, post-intervention. A 3 × 2 ANOVA determined differences in group score changes across time. Findings. Data from 28 employees (14/group) showed group-by-time interaction reached statistical significance for both relative mastery (F = 3.17, df = 2, p = .05) and team development (F = 8.38, df = 2, p = .001). Implications. OA-based training may improve dementia care teams' collaborative mastery over real-world challenges. While preliminary findings inform program developers, further research must explore clinical effectiveness.

Anonymous online cognitive behavioral therapy for sleep disorders in shift workers-a study protocol for a randomized controlled trial

Background

Many shift workers suffer from sleep issues, which negatively affect quality of life and performance. Scientifically evaluated, structured programs for prevention and treatment are scarce. We developed an anonymous online cognitive behavioral therapy for insomnia (CBT-I) program. After successful completion of a feasibility study, we now start this prospective, randomized, controlled superiority trial to compare outcomes of two parallel groups, namely an intervention group and a waiting-list control-group. Additionally, we will compare these outcomes to those of a face-to-face CBT-I outpatient sample.

Methods

Collaborating companies will offer our anonymous online intervention to their shift-working employees. Company physicians and counseling services will screen those interested for inclusion and exclusion criteria. Participants will receive access to our online service, where they will complete psychometric assessment and receive random assignment to either the intervention group or the waiting-list control group. Participants and providers will be aware of the group assignment. We aim to allocate at least N = 60 participants to the trial. The intervention consists of psychoeducation, sleep restriction, stimulus control, relaxation techniques, and individual feedback delivered via four e-mail contacts. During the intervention, as well as during the waiting period, participants will fill out weekly sleep diaries. Immediately after completion of the program, the post-intervention assessment takes place. Participants in the control group will be able to participate in the program after all study assessments. To recruit an additional sample, collaborating outpatient sleep clinics will provide six sessions of standard face-to-face CBT-I to an ad hoc sample of shift working patients. We expect both the online and the face-to-face CBT-I interventions to have beneficial effects compared to the control group on the following primary outcomes: self-reported symptoms of depression and insomnia, sleep quality, and daytime sleepiness.

Conclusions

The online intervention allows shift workers to follow a CBT-I program independently of their working schedule and location. Forthcoming results might contribute to further improvement of prevention and therapy of sleep issues in shift workers.

Study Registration for the Field of Prevention Science: Considering Options and Paths Forward

The practice of prospectively registering the details of intervention studies in a public database or registry is gaining momentum across disciplines as a strategy for increasing the transparency, credibility, and accessibility of study findings. In this article, we consider five registries that may be relevant for registration of intervention studies in the field of prevention science: ClinicalTrials.gov, the American Economic Association Registry of Randomized Controlled Trials (AEA RCT Registry), the Open Science Framework Preregistration (OSF Preregistration), the Registry for International Development Impact Evaluations (RIDIE), and the Registry of Efficacy and Effectiveness Studies (REES). We examine the five registries in terms of substantive focus, study designs, and contents of registry entries. We consider two paths forward for prospective registration of intervention studies in the field of prevention science: Path A: register all studies in ClinicalTrials.gov and Path B: allow individual researchers to select the registry with the "best fit." Lastly, we consider how the field might begin to establish norms around registration.

Longitudinal effect of nutritional intervention on body weight: A randomized controlled trial

OBJECTIVES

This study evaluates, in the medium and long term (12, 36, and 48 mo), the effect of an intervention to promote consumption of fruit and vegetables on the body weight of Brazilian primary health care users.

METHODS

A follow-up with participants (n = 3414) in a controlled randomized trial was performed in a primary health care service. Those in the control group performed the service's usual intervention (guided physical exercise 3 times/wk), and those in the intervention group additionally participated for 7 mo in collective activities to promote consumption of fruit and vegetables. Sociodemographic, health, and body weight data were collected by face-to-face interview at baseline and after 12 mo. At 36 and 48 mo, weight was obtained by telephone interview and was validated. Adherence to the intervention was assessed by the presence of the actions. Weight change (Δ) was measured by subtracting the weight at each follow-up time from the baseline measurement.

RESULTS

Participants in both groups had a minor weight loss of about 0.1 kg over 12, 36, and 48 mo. The addition of an intervention for consumption of fruit and vegetables did not enhance this effect. Higher weight loss was observed in individuals with obesity classes II and III with low adherence in the intervention and after 36 mo (Δ = -27.1 kg; P = 0.024).

CONCLUSIONS

Participating in the primary health care service contributed to a small reduction in weight, and the intervention for consumption of fruit and vegetables did not enhance this effect. However, greater weight loss was observed in participants with obesity and those who adhered to the intervention.

The (cost-)effectiveness of an implemented fall prevention intervention on falls and fall-related injuries among community-dwelling older adults with an increased risk of falls: protocol for the in balance randomized controlled trial

Background

Falls and fall-related injuries among older adults are a serious threat to the quality of life and result in high healthcare and societal costs. Despite evidence that falls can be prevented by fall prevention programmes, practical barriers may challenge the implementation of these programmes. In this study, we will investigate the effectiveness and cost-effectiveness of In Balance, a fourteen-week, low-cost group fall prevention intervention, that is widely implemented in community-dwelling older adults with an increased fall risk in the Netherlands. Moreover, we will be the first to include cost-effectiveness for this intervention. Based on previous evidence of the In Balance intervention in pre-frail older adults, we expect this intervention to be (cost-)effective after implementation-related adjustments on the target population and duration of the intervention.

Methods

This study is a single-blinded, multicenter randomized controlled trial. The target sample will consist of 256 community-dwelling non-frail and pre-frail adults of 65 years or older with an increased risk of falls. The intervention group receives the In Balance intervention as it is currently widely implemented in Dutch healthcare, which includes an educational component and physical exercises. The physical exercises are based on Tai Chi principles and focus on balance and strength. The control group receives general written physical activity recommendations. Primary outcomes are the number of falls and fall-related injuries over 12 months follow-up. Secondary outcomes consist of physical performance measures, physical activity, confidence, health status, quality of life, process evaluation and societal costs. Mixed model analyses will be conducted for both primary and secondary outcomes and will be stratified for non-frail and pre-frail adults.

Discussion

This trial will provide insight into the clinical and societal impact of an implemented Dutch fall prevention intervention and will have major benefits for older adults, society and health insurance companies. In addition, results of this study will inform healthcare professionals and policy makers about timely and (cost-)effective prevention of falls in older adults.

Effects of a self-monitoring intervention in breast cancer patients suffering from taste alterations induced by chemotherapy: A randomized, parallel-group controlled trial

PURPOSE

This study evaluates the effect of a self-monitoring intervention on taste alterations in breast cancer patients undergoing outpatient chemotherapy.

METHODS

The study was a randomized controlled trial. Thirty-four participants were divided into two groups: a self-monitoring (SMG) group (n = 17) and a control group (CG) (n = 17). A conceptual framework was developed with reference to the components of self-management, cognitive behavioral therapy, and the concepts of self-monitoring. Interventions were based on this framework. SMGs recorded their taste symptoms as homework and worked with the researcher to set goals and provide feedback four times every three weeks. In the feedback, the researcher actively listened to the SMG about their feelings and coping strategies during the taste changes, and gave approval and praise for these. The implementation period was 9 weeks for each participant; the CG was provided with conventional nursing support. The intervention was evaluated by comparing the items of symptom improvement, quality of life (QOL), and self-efficacy between the groups before and after the start of the intervention using a scale score. Scale scores were also compared for recognition of taste changes, concerns during treatment, distress, and impacts on each treatment day.

RESULTS

SMG had significantly lower scores than CG for perceived change in taste (p = 0.009), and there was an interaction with CG (p = 0.008). SMG had also significantly lower scores than CG in concern during treatment (p = 0.015).

CONCLUSION

This study showed that a self-monitoring intervention reduced negative cognition of taste alterations and reduced discomfort. The results suggest that the self-monitoring intervention is effective nursing support for chemotherapy-induced taste alterations.

Effects of a theory of planned behavior-based intervention on breastfeeding behaviors after cesarean section: A randomized controlled trial

Objectives

To examine the efficacy of an intervention based on the theory of planned behavior (TPB) in improving breastfeeding behavior among women with cesarean sections (C-sections).

Methods

This research was a randomized controlled trial. Women with planned elective C-sections were recruited to participate in a randomized controlled trial between June and September 2020. One hundred thirty-two women were divided randomly into the intervention (n = 66) and control group (n = 66) by systematic random sampling. In the intervention group, an intervention project was implemented after the C-section to establish positive breastfeeding attitudes, cultivate supportive subjective norms, enhance perceived behavioral control, and strengthen breastfeeding intention to change behaviors. Those in the control group received routine pre-and post-delivery care. Exclusive breastfeeding rate and breast problem were collected at 5 days, 2 weeks, and 1 month after C-section. The modified Breastfeeding Attrition Prediction Tool (BAPT) on the first day in the hospital, two weeks, and one month after C-section and Numerical Rating Scale (NRS) 24 h postoperatively were used to compare the intervention effect between the two groups.

Results

After the intervention, the intervention group had significantly higher exclusive breastfeeding rates than the control group at five days (86.4% vs. 60.6%), two weeks (77.3% vs. 57.6%), and one month (74.2% vs. 50.0%) after the C-section. Besides, the intervention group was less likely to have sore nipples at five days (6.1% vs. 18.2% in the control group, P < 0.05) and two weeks (9.1% vs. 12.1% in the control group, P < 0.05). After two weeks of intervention, attitude scores (90.64 ± 8.31 vs. 87.20 ± 8.15, P < 0.05), subjective norm scores (88.07 ± 24.65 vs. 79.42 ± 19.47, P < 0.05）and behavior control scores in the intervention group were significantly higher than those in the control group. After one month of intervention, attitude scores (90.34 ± 10.35 vs. 84.22 ± 10.51, P < 0.05) and behavior control scores (43.13 ± 5.02 vs. 39.15 ± 4.69, P < 0.05）in the intervention group were significantly higher than those in the control group, which resulted in the higher breastfeeding intention in the intervention group.

Conclusion

This study indicated that the TPB-based interventions effectively improved women's breastfeeding behaviors after C-sections.

Efficacy of the Cognitive Orientation to daily Occupational Performance (CO-OP) approach with and without parental coaching on activity and participation for children with developmental coordination disorder: A randomized clinical trial

BACKGROUND

Cognitive Orientation to daily Occupational Performance (CO-OP) is recommended for its effectiveness in improving activity performance in children with Developmental Coordination Disorder (DCD). Since parental support is a key element in CO-OP, parental coaching seems relevant to be investigated.

AIMS

Compare the efficacy of the CO-OP Approach with and without additional parental coaching to improve activity and participation in children with DCD.

METHODS AND PROCEDURES

Randomized clinical trial with 7-12-years-old children with DCD, randomly assigned to experimental (E-group) or active control (AC-group) groups, with 11 children each. Both groups received traditional CO-OP, E-group received four additional parental group-coaching sessions. Occupational performance and satisfaction on intervention goals were measured at baseline, post-intervention, and follow-up. Participation, motor performance and executive function were assessed at baseline and post-intervention.

OUTCOMES AND RESULTS

CO-OP with and without additional parental coaching resulted in improved occupational performance according to children, parents, and external evaluators. Children showed statistically significant gains in motor performance and cognitive flexibility. Participation measures did not change.

CONCLUSIONS AND IMPLICATIONS

As coaching did not add additional gains, parent's required participation in CO-OP might be enough to support children's occupational performance.

Indoor Nature Interventions for Health and Wellbeing of Older Adults in Residential Settings: A Systematic Review

BACKGROUND AND OBJECTIVES

Having contact with nature can be beneficial for health and wellbeing, but many older adults face barriers with getting outdoors. We conducted a systematic review of quantitative studies on health and wellbeing impacts of indoor forms of nature (both real and simulated/artificial), for older adults in residential settings.

RESEARCH DESIGN AND METHODS

Search terms relating to older adults and indoor nature were run in 13 scientific databases (MEDLINE, CINAHL, AgeLine, Environment Complete, AMED, PsychINFO, EMBASE, HMIC, PsychARTICLES, Global Health, Web of Knowledge, Dissertations and Theses Global, and ASSIA). We also pursued grey literature, global clinical trials registries, and a range of supplementary methods.

RESULTS

Of 6,131 articles screened against eligibility criteria, 26 studies were accepted into the review, and were quality-appraised using the Effective Public Health Practice Project (EPHPP) tool. The participants were 930 adults aged over 60. Nature interventions and health/wellbeing outcomes were heterogeneous, which necessitated a narrative synthesis. The evidence base was generally weak, with 18 of 26 studies having a high risk of bias. However, several higher-quality studies found indoor gardening and horticulture programs were effective for cognition, psychological wellbeing, social outcomes, and life satisfaction.

DISCUSSION AND IMPLICATIONS

There is inconsistent evidence that indoor nature exposures are beneficial for older care residents. We expect that successful interventions were, at least partly, facilitating social interaction, supporting feelings of autonomy/control, and promoting skill development, that is, factors not necessarily associated with nature per se. Higher-quality studies with improved reporting standards are needed to further elucidate these mechanisms.

Interventions to increase uptake of Human Papillomavirus (HPV) vaccination in minority populations: A systematic review

•

Nine studies intervened on vaccination in racial/ethnic and sexual and gender minorities.

•

Education and reminders increased HPV vaccine series initiation and completion.

•

Lack of high-quality, adequately powered studies warrants further investigation.

Minority youth represent a unique population for public health interventions given the social, economic, and cultural barriers they often face in accessing health services. Interventions to increase uptake of Human Papillomavirus (HPV) vaccination in minority youth have the potential to reduce disparities in HPV infection and HPV-related cancers. This systematic review assesses the effectiveness of interventions to increase HPV vaccine uptake, measured as vaccine series initiation and series completion, among adolescents and young adults, aged 9–26 years old, identifying as a racial and ethnic minority or sexual and gender minority (SGM) group in high-income countries.

Of the 3013 citations produced by a systematic search of three electronic databases (PubMed, Embase, and Web of Science) in November 2018, nine studies involving 9749 participants were selected for inclusion. All studies were conducted in the United States and were published from 2015 to 2018. Interventions utilized education, vaccine appointment reminders, and negotiated interviewing to increase vaccination. Participants were Black or African American (44.4%), Asian (33.3%), Hispanic or Latinx (22.2%), American Indian or Alaska Native (11.1%), and SGM (22.2%). Studies enrolled parent–child dyads (33.3%), parents alone (11.1%), and youth alone (55.6%). Vaccine series initiation ranged from 11.1% to 84% and series completion ranged from 5.6% to 74.2% post-intervention. Educational and appointment reminder interventions may improve HPV vaccine series initiation and completion in minority youth in the U.S. Given the lack of high quality, adequately powered studies, further research is warranted to identify effective strategies for improving HPV vaccine uptake for minority populations.

Status and future directions of clinical trials in Parkinson's disease

Novel therapies are needed to treat Parkinson's disease (PD) in which the clinical unmet need is pressing. Currently, no clinically available therapeutic strategy can either retard or reverse PD or repair its pathological consequences. l-DOPA (levodopa) is still the gold standard therapy for motor symptoms yet symptomatic therapies for both motor and non-motor symptoms are improving. Many on-going, intervention trials cover a broad range of targets, including cell replacement and gene therapy approaches, quality of life improving technologies, and disease-modifying strategies (e.g., controlling aberrant α-synuclein accumulation and regulating cellular/neuronal bioenergetics). Notably, the repurposing of glucagon-like peptide-1 analogues with potential disease-modifying effects based on metabolic pathology associated with PD has been promising. Nevertheless, there is a clear need for improved therapeutic and diagnostic options, disease progression tracking and patient stratification capabilities to deliver personalized treatment and optimize trial design. This review discusses some of the risk factors and consequent pathology associated with PD and particularly the metabolic aspects of PD, novel therapies targeting these pathologies (e.g., mitochondrial and lysosomal dysfunction, oxidative stress, and inflammation/neuroinflammation), including the repurposing of metabolic therapies, and unmet needs as potential drivers for future clinical trials and research in PD.

Proactive outreach tobacco treatment for socioeconomically disadvantaged smokers with serious mental illness

Smokers with serious mental illness (SMI) face individual, interpersonal, and healthcare provider barriers to cessation treatment utilization and smoking abstinence. Proactive outreach strategies are designed to address these barriers by promoting heightened contact with smokers and facilitating access to evidence-based treatments. The present study examined the effect of proactive outreach among smokers with SMI (n = 939) who were enrolled in the publicly subsidized Minnesota Health Care Programs (MHCP) and compared this effect to that observed among MHCP smokers without SMI (n = 1382). Relative to usual care, the intervention increased treatment utilization among those with SMI (52.1% vs 40.0%, p = 0.002) and without SMI (39.3% vs 25.4%, p < 0.001). The intervention also increased prolonged smoking abstinence among those with SMI (14.9% vs 9.4%, p = 0.010) and without SMI (17.7% vs 13.6%, p = 0.09). Findings suggest that implementation of proactive outreach within publicly subsidized healthcare systems may alleviate the burden of smoking in this vulnerable population.

The transtheoretical model is an effective weight management intervention: a randomized controlled trial

Background

Given the current worldwide epidemic of obesity, there is a demand for interventions with higher impact, such as those carried out in the primary health care (PHC) setting. Here we evaluate the effect of intervention performed according to the stages of change of the transtheoretical model (TTM) for weight management.

Methods

This randomized controlled trial in Brazilian PHC offered free physical exercise and nutrition education. The participants were women, aged 20 years or older who were obese or overweight, users in PHC service. The intervention group (IG, n = 51) received the same orientation as the comparison group (CG, n = 35) plus individual health counseling based on the TTM aimed at weight loss, which lasted 6 months. The outcome measures were anthropometric, food, and nutrient profiles. Inflammatory parameters were evaluated in a random subsample. The inter-group and intra-group differences were evaluated using interntion-to-treat analysis, and analysis of covariance (ANCOVA) used to assess intervention effectiveness.

Results

There was a difference between groups of − 1.4 kg (CI95%: − 2.5; − 0.3) in body weight after the intervention. About 97% of women in the IG reported benefits of the intervention and presented positive changes in diet, biochemical markers, and anthropometry. The IG showed better body mass index, resistine, and blood glucose results compared to the CG during follow-up.

Conclusion

The individualized TTM-based intervention, combined with usual care, was an effective strategy in PHC. These results should encourage the use of interdisciplinary practices; nevertheless, research to identify additional strategies is needed to address barriers to weight maintenance among obese low-income women.

Trial registration

The trial is registered with Brazilian clinical trials under the code: RBR-8t7ssv, Registration date: 12/12/2017 (retrospectively registered).

[Real world study of influenza vaccination intervention among key population of chronic disease management in Shanghai community]

Objective: To analyze the effect of influenza vaccination intervention among key populations of chronic disease management in communities of Shanghai. Methods: A total of 50 787 patients aged ≥60 with diabetes, hypertension and chronic obstructive pulmonary disease (COPD) in Huangpu, Yangpu, Baoshan and Qingpu districts of Shanghai from January 2013 to August 2017 were selected as the intervention group, and 52 268 people from key populations with chronic disease management in Xuhui, Hongkou, Jiading and Fengxian districts were selected as the control group according to the geographical location and economic level. The intervention group accepted follow-up and health education of influenza vaccination via chronic disease outpatient based on information system. The implementation time of the intervention was from September 2017 to January 2018. The basic information and diagnosis information of two groups, and intervention completion of the intervention group were obtained from Shanghai chronic disease management information system and hospital record system. Results: The age of the intervention group and the control group were (76.76±8.33) and (77.97±8.51) years old, respectively (P<0.001); and there were statistical differences in gender, occupational and influenza vaccination rate between the two groups (P<0.001). A total of 28 644 (56.40%) subjects of the intervention group received intervention. There was no significant difference in age composition between finished and unfinished intervention groups (P=0.095), and there was significant difference in gender composition (P=0.044). Before the intervention, the vaccination rate of the intervention group was 0.75% (382 subjects) which was lower than that of the control group with 1.02% (533 subjects) (χ(2)=20.96, P<0.001). After the intervention, the vaccination rate of the intervention group was 1.73% (496 subjects) which was higher than that of the control group with 1.42% (744 subjects) (χ(2)=11.65, P=0.001). Subjects that were male, younger, uptake of influenza vaccine before the intervention, received intervention and professional and technical personnel were more likely to take influenza vaccine, with OR (95%CI) 1.29 (1.13-1.47), 0.97 (0.96-0.98), 260.30 (215.21-314.83), 1.85 (1.61-2.11) and 1.48 (1.10-1.99), respectively. Conclusion: Influenza vaccination intervetion raised the vaccination rate of key population of chronic disease management. Male, younger, those who had been vaccinated before the intervention, who received the intervention, and professional and technical personnel were more likely to be vaccinated.

[Effectiveness of peer-supported self-management group intervention in patients with type 2 diabetes]

Objective: To assess the effectiveness of peer-supported diabetes self-management group intervention and explore a community-based diabetes health management model. Methods: From September to December in 2016, patients with type 2 diabetes were recruited from 6 streets (townships) in Binhu and Xishan district of Wuxi, Jiangsu Province. According to a structured diabetes self-management course, guidance was provided by community health workers and peer volunteers. Self-management group intervention was led by type 2 diabetes patients. A self-control design was used to collect information on self-management behavior, fasting blood glucose, and health care utilization at baseline and after 4-month intervention, and compare the difference of these indicators before and after the intervention. Results: Compared with the baseline, 147 participants aged from 30 to 80 years old had more increases in proportions of salt control (78.2% vs 60.5%, P<0.001) and oil control (79.6% vs 58.5%, P<0.001) in daily diet. The P(50) (P(25), P(75)) of scores of symptom management and consultation list increased from 6 (0, 11) and 0 (0, 2) to 9 (4, 13) and 1 (0, 2) (P<0.05) after 4-month intervention. Fasting blood glucose significantly decreased from (8.8±2.9) mmol/L at baseline to (7.6±1.9) mmol/L and the control rate of blood glucose significantly increased from 29.3% to 44.2% (P<0.05) after 4-month intervention. The proportion of outpatient visited decreased from 42.2% to 12.9% and the proportion of hospitalized decreased from 10.2% to 4.1% (P<0.05) after 4-month intervention. Conclusion: Peer-supported diabetes self-management group intervention could effectively improve behavior and blood glucose control of patients with type 2 diabetes.

Child Development Outcomes of DIR/Floortime TM-based Programs: A Systematic Review

BACKGROUND

Occupational therapy is often part of the multi-disciplinary approach within the Developmental, Individual-differences, Relationship-based (DIR) FloortimeTM Model. The model addresses the emotional development of children, which is considered to be critical for the other child developmental areas.

PURPOSE

This review serves to inform practitioner decision-making about the use of this model, as no systematic reviews exist on child development outcomes.

METHODS

The systematic search included Medline, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, and Cochrane. For critical appraisal, the McMaster Critical Review was utilized.

FINDINGS

Nine studies were identified with varying quality levels. Outcomes were mostly reported for increased socio-emotional development.

IMPLICATIONS

The evidence base for this model is emerging from a published research perspective. It is recommended that the use of this model be supported by sound clinical reasoning processes, intervention fidelity, use of valid outcome measures, and regular monitoring. Higher quality research is urgently needed to progress the research base for this intervention.

[Effectiveness evaluation of health belief model-based health education intervention for patients with hypertension in community settings]

Objective: To evaluate the effectiveness of health belief model-based health education intervention in improving blood pressure control of patients with hypertension in community settings. Methods: From September 2016 to September 2017, 400 newly diagnosed patients with hypertension were recruited from 6 community healthcare centers with comparable population size and health services in the Shunyi District of Beijing. All community healthcare centers were randomly assigned to the intervention group (206 patients) and the control group (194 patients). Patients in the intervention group received 3 lectures (20-30 min for each) of health belief model-based health education. Patients in the control group received usual care. The basic characteristics, health beliefs, and health literacy were collected, and blood pressure was measured before and after the intervention, respectively. The difference-in-difference model was used to analyze the change of blood pressure and the influencing factors between two groups before and after the intervention. Results: A total of 134 patients in the intervention group and 129 patients in the control group completed the study. After adjusting for the age, gender, family income, medical insurance, chronic diseases and family history, the score of perceived barriers was increased by 1.65 (P=0.016), and perceived seriousness was decreased by 0.73 (P=0.018). The systolic blood pressure of patients was decreased by 7.37 mmHg (1 mmHg=0.133 kPa, P=0.001) and diastolic blood pressure was decreased by 4.07 mmHg (P=0.014), respectively. The β (95%CI) values were -7.37 (-11.88,-2.86) and -4.07 (-7.30, -0.84). The perceived susceptibility and self-efficacy had a significant influence on the blood pressure of patients (P<0.05). Conclusion: Health belief model-based health education intervention could significantly improve the blood pressure control of patients with hypertension in the community settings.

Parent adoption and implementation of obesity prevention practices through building children's asking skills at family child care homes

BACKGROUND

Early childhood education programs provide a setting to reach children and parents to modify home environments to prevent obesity. The Healthy Opportunities for Physical Activity and Nutrition Home (HOP'N) Home project was a novel approach that linked Family Child Care Homes (FCCH) to home environments by developing children's asking skills for healthful home environmental change through curricular activities.

OBJECTIVE

To evaluate the feasibility of engaging parents in obesity prevention practices through building children's asking skills at FCCH.

METHODS

FCCHs (n = 5 settings) and children (n = 25; aged 3-5 years; female = 36 %; non-Hispanic white = 91 %; low socioeconomic status = 28 %; overweight/obese = 52 %) and parents (n = 25) participated in a pre-post cohort design. We assessed children's body mass index and self-report variables at three time points. HOP'N Home included continuous staff training, group time, dramatic play, meal prompts, songs, and home activities.

RESULTS

FCCH providers implemented 83%-100% of intervention activities. All parents (100 %) adopted the program, most (87 %) returned completed homework activities to FCCHs, and over 90 % implemented changes in the home. Percent of overweight/obese children decreased from pre-intervention (50 %) to post-intervention (29 %,p = 0.06) and follow-up (38 %,p = 0.06).

CONCLUSIONS

It is feasible to build children's asking skills and pair this strategy with home activities to engage parents to prevent obesity.

Association between intensive health guidance focusing on eating quickly and metabolic syndrome in Japanese middle-aged citizens

PURPOSE

The purpose of this intervention study was to investigate whether intensive health guidance focusing on eating quickly can prevent metabolic syndrome (MetS) more effectively than standard routine guidance in Japanese citizens living in rural areas.

METHODS

This controlled, non-randomized, intervention study analyzed 141 participants with MetS at baseline. Participants in the intervention group received health guidance focusing on eating quickly and standard health guidance about MetS in accordance with the guidelines of the Ministry of Health, Labour and Welfare in Japan, whereas participants in the control group received only standard health guidance about MetS. The primary study outcome was the prevalence of MetS at a 1-year follow-up.

RESULTS

At 1-year follow-up, the prevalence of MetS in the intervention group was significantly lower than that in the control group (p = 0.003). The decreases in body weight, body mass index, waist circumference and triglycerides from baseline to 1 year were significantly greater in the intervention group than in the control group (p < 0.05).

CONCLUSION

Intensive health guidance focusing on eating quickly is more effective for improving MetS than standard Japanese health guidance alone.

Effects of Church-Based Parent-Child Abstinence-Only Interventions on Adolescents' Sexual Behaviors

PURPOSE

The aim of the study was to evaluate the efficacy of faith-based and nonfaith-based parent-child abstinence-only interventions in reducing sexual risk behavior among young African American adolescents.

METHODS

Randomized controlled trial recruiting 613 African American parent-adolescent dyads from urban African American Baptist churches and randomizing them to one of three parent-child interventions: faith-based abstinence-only intervention emphasizing delaying or reducing sexual intercourse drawing on Biblical scriptures; nonfaith-based abstinence-only emphasizing intervention delaying or reducing sexual intercourse without referencing scriptures; or attention-matched control intervention targeting health issues unrelated to sexual behavior. Primary outcome was the self-reported frequency of condomless sexual intercourse in the past 3 months assessed periodically through 18 months postintervention. Secondary outcomes were frequency of sexual intercourse, number of sexual partners, consistent condom use and, among sexually inexperienced adolescents, sexual debut.

RESULTS

Generalized estimating equations analyses revealed that nonfaith-based abstinence-only intervention reduced the frequency of condomless sexual intercourse, frequency of sexual intercourse, and number of sexual partners compared with the attention-matched control intervention, whereas faith-based abstinence-only intervention did not. Neither intervention affected consistent condom use or sexual debut.

CONCLUSIONS

Parent-child abstinence-only interventions can reduce condomless sexual intercourse among young African American adolescents in church settings. Linking the abstinence message to Biblical scriptures may not be efficacious.

Recruitment and retention of fathers with young children in early childhood health intervention research: a systematic review and meta-analysis protocol

BACKGROUND

Fathers are under-represented in research and programs addressing early childhood health and development. Recruiting fathers into these interventions can be hampered for multiple reasons, including recruitment and retention strategies that are not tailored for fathers. The primary aim of this systematic review and meta-analysis is to determine the effectiveness of recruitment and retention strategies used to include fathers of children (from conception to age 36 months) in intervention studies. The secondary aim is to investigate study-level factors that may influence recruitment and retention.

METHODS

We will conduct searches for scholarly peer-reviewed randomized controlled trials, quasi-experimental studies, and pre-post studies that recruited fathers using the following databases: MEDLINE (Ovid), EMBASE (Ovid), PsycINFO (Ovid), and CINAHL. English-language articles will be eligible if they recruited self-identified fathers of children from conception to age 36 months for health-promoting interventions that target healthy parents and children. Two reviewers will independently screen titles/abstracts and full texts for inclusion, as well as grading methodological quality. Recruitment and retention proportions will be calculated for each study. Where possible, we will calculate pooled proportional effects with 95% confidence intervals using random-effects models and conduct a meta-regression to examine the impact of potential modifiers of recruitment and retention.

DISCUSSION

Findings from this review will help inform future intervention research with fathers to optimally recruit and retain participants. Identifying key factors should enable health researchers and program managers design and adapt interventions to increase the likelihood of increasing father engagement in early childhood health interventions. Researchers will be able to use this review to inform future research that addresses current evidence gaps for the recruitment and retention of fathers. This review will make recommendations for addressing key target areas to improve recruitment and retention of fathers in early childhood health research, ultimately leading to a body of evidence that captures the full potential of fathers for maximizing the health and wellbeing of their children.

Barriers to and facilitators for adherence to nutritional intervention: Consumption of fruits and vegetables

OBJECTIVES

The aim of this study was to investigate the barriers and facilitators for the adherence of participants to a nutritional intervention.

METHODS

A randomized controlled trial was carried out with participants from the Health Academy Program in Belo Horizonte, MG, Brazil. The intervention (7 mo) was based on the Transtheoretical Model and on Paulo Freire's pedagogy and offered 12 education activities with the purpose of promoting the consumption of fruits and vegetables. Adherene was determined by calculating the participation percentage (attendance at activities/number of activities).

RESULTS

In all, 1483 individuals participated and the average adherence was 58.3%. Low adherence was demonstrated by 24.3%, medium adherence by 26.5%, and high adherence by 49.2% of the participants. Adherence was associated with aging (odds ratio [OR], 1.97; 95% CI, 1.33-2.94), being unemployed (OR, 0.75; 95% CI, 0.58-0.95), not being under psychiatric treatment (OR, 0.77; 95% CI, 0.63-0.95), participant body satisfaction (OR, 1.27; 95% CI, 1.02-1.58) and participant attendance at the Health Academy Program for >1 y (OR, 2.78; 95% CI, 2.17-3.56). The qualitative analysis revealed the following facilitators for adherence: service structure, intervention methodology, bond-building among users and professionals, family support, and patient-associated aspects. The barriers to adherence included work, self-care, and care for another.

CONCLUSION

Adherence to the intervention was high, and the patient-associated aspects, the logistics of the Health Academy Program, and the methodology appeared to contribute to adherence. However, the timetable was a barrier for those who were working and for those who support their families.

[The design of interrupted time series and its analytic methods]

Interrupted time series (ITS) is a statistical method for the quasi-experimental design specific to the outcome of time series, in which the effectiveness of an intervening measure is evaluated by examining change in slope and immediate change in level. The key feature of ITS is that the secular trend of time series prior to the intervention can be effectively controlled so as to accurately estimate the intervention effect. The design principle and statistical method for ITS were illustrated by an example of evaluating halving policy for the expert registration fee in the general hospital of a city. The segmented linear regression was used to fit the above time series data and the results were explained in detail. Meanwhile, the study design and model fitting along with explanations of the results with respect to the effects of two types of successive interventions and on different time-points of an intervention were illustrated as well in this paper. The existed upward or downward trend should be taken into account in order to accurately estimate the intervention effect as it exists in most of the public health surveillance data. Two parameters, known as change in slope and immediate change in level, were employed to evaluate the effect of the intervention. The ITS analysis can be widely applied to the program evaluation as it could enrich methods of the evaluation compared to the traditional model of the program evaluation.

Study Protocol for a Randomized Controlled Trial Evaluating the Efficacy of an Evidence-Based iPad-App for Cognitive Rehabilitation in Patients with Primary Brain Tumors

BACKGROUND

Many patients with primary brain tumors suffer from cognitive deficits, which negatively impact their quality of life. However, cognitive rehabilitation programs for these patients are scarce. We developed an iPad-based cognitive rehabilitation program for brain tumor patients, which was based on our effective face-to-face cognitive rehabilitation program. After successful completion of a feasibility study, a randomized controlled trial has been started.

OBJECTIVE

To evaluate the immediate and long-term effects of the iPad-based program on cognitive performance and patient-reported outcome measures (PROMs) in patients with primary brain tumors in an early stage of the disease.

METHODS

Prior to surgery, patients with presumed low-grade glioma and meningioma are included. Before surgery and 3 mo after surgery, neuropsychological assessments are conducted. After the second neuropsychological assessment, patients are assigned to the intervention group or waiting-list control group. The intervention consists of psychoeducation, compensation training, and retraining. Patients are advised to spend 3 h per week on the program for 10 wk. Immediately after completion of the program and a half-year thereafter, postintervention assessments take place. Patients in the control group are offered the opportunity to follow the program after all study assessments.

EXPECTED OUTCOMES

We expect that early cognitive rehabilitation has beneficial effects on cognitive performance and PROMs in brain tumor patients.

DISCUSSION

The iPad-based program allows brain tumor patients to follow a cognitive rehabilitation program from their homes. Forthcoming results may contribute to further improvement of supportive care for brain tumor patients.

[Effects of short-term intervention of walking on body mass index, waist circumference, and related indicators of working population]

Objective: To quantify the effects of short-term walking intervention on body mass index (BMI), waist circumference, and related indicators of working population. Methods: The China Motivational Healthy Walking Program in 2016 recruited 29 224 individuals from 139 demonstration areas for comprehensive prevention and control of chronic and non-communicable diseases at the national level and 70 areas at the provincial level. All subjects volunteered to participate into this program. The intervention lasted 100 days from June to September 2016. The walking behavior, height, weight and waist circumference of subjects were measured using a uniform pedometer, body composition tester, height tester and waist-to-hip caliper before and after the intervention. Daily average steps, daily average effective steps, and the percent of fulfilling continuous walking per day were used as main indicators in this study. Self-administered questionnaires were used to collect demographic characteristics, behaviors and chronic diseases. With the adjustment of potential confounding factors, multilevel regression was used to quantify the effect of walking on BMI and waist circumference, and multilevel logistic regression was used to quantify the effect on overweight or obesity and central obesity. Results: A total of 12 368 subjects completed walking interventions and all measurements included in this study. The mean±SD age of all subjects was (41.19±8.99) years, and 5 155 (59.17%) of them were women. After 100-day intervention, all outcome variables decreased significantly. For every additional 1 000 steps per day, subjects would have extra decrease in BMI of 0.023 kg/m(2) [β (95%CI): -0.023 (-0.030, -0.017)], in waist circumference of 0.046 cm [β (95%CI): -0.046 (-0.071, -0.020)], and the likelihood for becoming overweight or obesity was 0.97 times [OR (95%CI): 0.97 (0.95, 0.98)] that of before intervention. With additional 1 000 effective steps per day, the difference between baseline and endpoint increased by 0.028 kg/m(2) [β (95%CI): -0.028 (-0.035, -0.020)] in BMI and 0.062 cm [β (95%CI): -0.062 (-0.091, -0.033)] in waist circumference. The likelihood of progressing into overweight or obesity was 0.97 times [OR (95%CI): 0.97(0.95, 0.98)] that of before-intervention, and the likelihood of becoming central obesity was 0.98 times [OR (95%CI): 0.98(0.96, 0.99)] that of before-intervention. Compared to subjects with low level percent of fulfilling continuous walking per day, those with high level would have an extra decrease in BMI by 0.150 kg/m(2) [β (95%CI): -0.150 (-0.22, -0.079)], in waist circumference by 0.340 cm [β (95%CI): -0.340 (-0.620, -0.064)], and the likelihood of becoming overweight or obesity decreased to 0.74 times that of the low level group [OR (95%CI): 0.74(0.62, 0.89)] and the likelihood of becoming central obesity decreased to 0.78 times that of the low level group [OR (95%CI): 0.78 (0.68, 0.91)]. Conclusion: Strengthening walking exercise in the short term has a positive effect on promoting working population to reduce BMI and waist circumference, and prevent overweight, obesity and central obesity.

[The impact evaluation of a community-based intervention supporting type 2 diabetes mellitus patients in their self-management of the disease]

Objective: To evaluate the effect of a community-based intervention supporting type 2 diabetes mellitus patients in their self-management of the disease. Methods: This research was a randomized controlled trial conducted in communities in Fangshan District, Beijing, China. Adult patients with type 2 diabetes from 17 communities in 4 sub-district of Fangshan District were randomly assigned to either the intervention or control group. Participants in the intervention group participated in a three-month group-based diabetes self-management intervention service. Data were collected both in intervention and control group at baseline and after the intervention to evaluate the effect of the intervention. A questionnaire survey was completed by all participants to collect their demographic information, diabetes related health behaviors and skills. A physical examination and lab testing including height, weight, blood pressure, and waist circumference as well as HbA1c, fasting blood glucose, lipid profile were conducted before and after the intervention. Results: A total of 500 valid questionnaires were received, including 259 in the intervention group and 241 in the control group. Patients in the intervention group who learned how to conduct the self-monitoring of blood glucose increased from 56.76% (n=147) to 87.26% (n=226) after the intervention, higher than that of control group (63.07%, n=152) (P<0.001). 69.50% (n=180) patients in intervention group had blood glucose monitor at home, which was 60.62% (n=157) prior to the intervention and higher than that of control group (57.68%, n=139) (P=0.004). After the intervention, 3.09% (n=8) patients in intervention group ceased to take medicine by themselves, which was 16.22% (n=42) before the intervention, while the control group was 8.30% (n=20) after the intervention (P=0.009). Patients in the intervention group made significant improvements in implementing self monitoring on blood glucose (SMBG), which was increased from one day per week to 2 days per week, and foot self-examination, which increased from 2 days per week to 7 days per week. The body weight of patients in the intervention group reduced 1.62 kg on average after the intervention, while it increased 0.88 kg in the control group. Similar improvement was found in waist circumstance between the intervention and control group (-0.83 cm vs -0.16 m). There was a significant reduction on body weight and waist circumstance in the intervention group (P<0.05). Conclusion: The group activities focusing on people with type 2 diabetes resulted in improvement in their lifestyle and self management behaviors, as well as their body weight and waist circumstance.

Behavioral interventions promoting HIV serostatus disclosure to sex partners among HIV-positive men who have sex with men: a systematic review

OBJECTIVES

This review aimed to identify intervention components which were effective to promote disclosure of HIV status among men have sex with men (MSM) living with HIV, particularly from a theoretical perspective.

METHODS

A systematic review was performed through searching electronic databases, HIV-related conferences websites, and registered ongoing randomized controlled trials. Studies were included if they reported intervention evaluation results related to HIV disclosure and published before December 31, 2017. Two independent reviewers collected studies and extracted data.

RESULTS

Eight studies met the inclusion criteria and were summarized. Interventions appeared effective in promoting HIV disclosure to their sex partners among MSM living with HIV if they were theory based (e.g., consequence theory and social cognitive theory). Key elements of effective interventions consisted of increasing disclosure self-efficacy, highlighting disclosure benefits, assisting risk assessment, developing disclosure strategy, and using messages under social influence.

CONCLUSIONS

Findings of this review imply that future interventions are more likely to succeed if they apply consequence theory, social cognitive theory, and trans-theoretical model of behavior change and include multiple key intervention components.

A systematic review of non-pharmacological interventions to improve therapeutic adherence in tuberculosis

BACKGROUND

Reviews examining non-pharmacological interventions to improve therapeutic adherence in tuberculosis have several limitations (design, quality assessment…). Consequently, for clinical practice, it is important to generate a review containing all the information to improve patient adherence, solving the previous issues.

OBJECTIVES

To examine non-pharmacological interventions to improve therapeutic adherence in tuberculosis through clinical trials.

METHODS

A systematic review in MEDLINE/EMBASE was performed.

RESULTS

Thirty seven papers were analysed. The disease treatment interventions were disparate, grouped into: education, psychological interventions, new technologies, directly observed treatment, incentives and improved access to health services. In the treatment of latent infection, the majority of studies were conducted in the marginal population (drug addicts, homeless individuals and prisoners) and were based mainly on the provision of incentives. Study quality was generally low.

CONCLUSIONS

Great variability exists in the studies comparing strategies for identifying interventions, objectives and effects. The designs carried out generally have methodological deficits.

[Evaluation on the effect of salt reduction intervention among fourth-grade primary school students and their parents in Shandong Province]

In order to evaluate the intervention effect of the school-based salt reduction model, 28 primary schools were selected in Shandong Province in September 2014 and randomly divided into intervention group (1 361 students, 1 306 parents) and control group (1 364 students,1 340 parents). A series of "small hands and big hands" salt reduction intervention activities were conducted in intervention group for 8 months. After the intervention, the total awareness rate of salt reduction knowledge, the total holding rate of related beliefs and the total reporting rate of related behaviors were 70.65%, 80.30% and 67.03% among students, and 85.66%, 93.77% and 87.93% among parents, in the intervention group, which were higher than those in the control group (37.12%, 66.52% and 50.07% among students; 55.11%, 87.52% and 57.96% among parents) (all P values <0.05). The school-based salt reduction model is effective and feasible.

Effects of physical activity interventions in frail and prefrail community-dwelling people on frailty status, muscle strength, physical performance and muscle mass-a narrative review

Background

Frailty is a geriatric syndrome, which is highly prevalent in community-dwelling older adults and is associated with a variety of unwanted health outcomes, including dependency and institutionalization. Physical activity (PA) interventions may be of great importance in frail people to improve the frailty status, muscle strength, physical performance and muscle mass.

Methods

A narrative review of randomized-controlled trails was performed, including frail and prefrail community-dwelling older adults. Included were studies with different PA interventions, such as aerobic activity, strength and balance training, stretching, and a combination of these methods.

Results

Overall, 14 studies were included. The PA interventions led to a significant reduction in the frailty status (3/5 studies), to an increase in muscle strength (4/8 studies), to improved physical performance (7/11 studies), and to an increase in muscle mass (1/4 studies), when compared to the control group. The studies analyzed differed in various aspects of study protocols (training protocol, intensity, frequency, follow-up time, measuring tools) and delivery method of intervention (health professionals, lay volunteers, at home in health care institutions).

Conclusions

Although it was not consistently reported in the studies that PA interventions are successful in increasing muscle mass in frail and prefrail older people, the results support the effectiveness of PA interventions on the reduction of frailty, and the increase in muscle strength and physical performance.

Effectiveness Evaluation of It's Your Game: Keep It Real, a Middle School HIV/Sexually Transmitted Infection/Pregnancy Prevention Program

PURPOSE

This study assessed the effectiveness of the HIV/sexually transmitted infection/pregnancy prevention program, It's Your Game: Keep It Real (IYG).

METHODS

IYG was implemented by classroom teachers in 24 urban middle schools from 2012 to 2015. Using a quasi-experimental design, each year we surveyed ninth-grade students in 10 high schools that were selected based on feeder patterns from project middle schools. We compared two groups of students (n = 4,562): (1) students whose middle school grade cohorts did not receive IYG ("No-IYG"), and (2) students whose middle school grade cohorts received IYG ("IYG"). Multilevel analyses examined differences between the two groups in the initiation of any type of sexual activity (oral, vaginal, or anal sex), presexual behaviors, and psychosocial mediators.

RESULTS

Students in the IYG group were less likely to report initiation of sexual activity by ninth grade compared to students in the No-IYG group (odds ratio .77; 95% confidence interval .66-.90). The IYG group was significantly less likely to have engaged in presexual behaviors, including having been on a date, had a boyfriend/girlfriend, and touched or been touched on private body parts. The IYG group had better outcomes on 11 of 19 psychosocial variables, including knowledge; beliefs about abstinence, sex, friends' beliefs, norms, and behaviors; reasons for not having sex; personal limits; exposure to risky situations; self-efficacy; and quality of dating relationships.

CONCLUSIONS

The results suggest that IYG, when implemented on a large scale by trained classroom teachers in urban public schools, had positive impacts on students' behaviors, beliefs, and knowledge.

(Outcome) Measure for (Intervention) Measures: A Guide to Choosing the Appropriate Noninvasive Clinical Outcome Measure for Intervention Studies in Celiac Disease

There is an unmet need for diagnostic and treatment interventions for celiac disease. Both clinical trials and real-world studies require careful selection of clinical outcome measures. Often, neither serology nor histology is an appropriate primary outcome. This article reviews various measures of intestinal function and nutrition, patient-reported outcome measures for symptoms and for health-related quality of life, and measures of sickness burden as they apply to intervention studies for celiac disease. A series of case studies is presented to illustrate key considerations in selecting outcome measures for dietary interventions, pharmacologic interventions, and real-world studies.

Pregnancy and Lactation: A Window of Opportunity to Improve Individual Health

Human and animal studies indicate that obesity during pregnancy adversely impacts both maternal health and offspring phenotype predisposing them to chronic diseases later in life including obesity, dyslipidemia, type 2 diabetes mellitus, and hypertension. Effective interventions during human pregnancy and/or lactation are needed to improve both maternal and offspring health. This review addresses the relationship between adverse perinatal insults and its negative impact on offspring development and presents some maternal intervention studies such as diet modification, probiotic consumption, or maternal exercise, to prevent or alleviate the negative outcomes in both the mother and her child.
