It's time to include the assessment of the aberrant right subclavian artery
as screening test on ultrasound examination at 18–21 weeks of gestation
Authors: M.V. Medvedev, A.Yu. Blinov, N.A. Altynnik et all
Published: April 2019

Aberrant right subclavian artery (ARSA) is the most common embryologic abnormality of the aortic arch.
3973 fetuses were examined by ultrasound at 12–34 weeks of gestation and 34 fetuses with ARSA (mean gestational age: 20.2 weeks) was identified in our centre. ARSA was assessed in the axial plane on the level of three
vessels and trachea view. ARSA was an isolated finding in 19 (55.9%) fetuses and non-isolated in 15 (44.1 %)
fetuses. 6 (17.6 %) of these of 34 were aneuploidies: Trisomy 21 was diagnosed in 5 fetuses, Trisomy 18 in 1 fetus.
22q11 microdeletion was detected in 1 fetus. No cases with chromosomal abnormalities were detected in all
19 fetuses with isolated ARSA. Isolated ARSA does not seem to be associated with a significantly increased risk
of aneuploidy. When ARSA is identified a detailed anatomy scan should be recommended. An invasive procedure with genetic diagnosis should be discussed when additional ultrasound abnormalities or risk factors for
aneuploidy are found. Prenatal ultrasound diagnosis of ARSA based on previously published cases are discussed.
Identification of resilience characteristics of a regional agricultural water resources system based on index optimization and improved support vector machine
Authors: Liu Dong , Xu Lei , Fu Qiang , Li Mo , Faiz Muhammad Abrar
Published: April 2019

In order to solve the gap and accuracy in the analytical methods of the resilience of a regional agricultural water resources system, a suitable evaluation index system based on the optimal index model was introduced and applied to the 15 farms in the Jiansanjiang Administration of Heilongjiang Province of China. An improved support vector machine (SVM) was used to analyze the resilience level of each farm for the selected time period. The test results showed that the indicator optimization model had the advantage of eliminating redundant indicators and ensuring the maximum content of screening indicators. The indicator system reflected all original information by 34% of initial indicators. The results showed that the particle swarm optimization-support vector machine (PSO-SVM) model had higher accuracy for the evaluation of agricultural water resource resilience through the analysis of stability and reliability of each model. The spatial pattern of resilience over selected farms was generally characterized by ‘low in the southwest and high in the northeast’. The research achievements may provide technical and theoretical support for solving problems of index optimization and analysis methods of system resilience, and have an important theoretical and practical significance for promoting the sustainable development of regional agricultural water resources systems.
Microbial ecological processes in MBBR biofilms for biological phosphorus removal from wastewater
Authors: Rudi Knut , Goa Inger Andrea , Saltnes Torgeir , Sørensen Gjermund , Angell Inga Leena , Eikås Sondre
Published: April 2019

Phosphorus is both a major environmental pollutant and a limiting resource. Although enhanced biological phosphorus removal (EBPR) is used worldwide for phosphorus removal, the standard activated sludge-based EBPR process shows limitations with stability and efficiency. Recently, a new EBPR moving bed biofilm reactor (MBBR) process has been developed at HIAS (Hamar, Norway), enabling a phosphorus removal stability above 90% during a whole year cycle. To increase the knowledge of the HIAS (MBBR) process the aim of the current work was to characterize the MBBR microbiota and operational performance weekly for the operational year. Surprisingly, we found a major succession of the microbiota, with a five-fold increase in phosphorus accumulating organisms (PAOs), and major shifts in eukaryote composition, despite a stable phosphorus removal. Temperature was the only factor that significantly affected both phosphorus removal and the microbiota. There was a lower phosphor removal during the winter, coinciding with a higher microbiota alpha diversity, and a lower beta diversity. This differs from what is observed for activated sludge based EBPR. Taken together, the knowledge gained from the current microbiota study supports the efficiency and stability of MBBR-based systems, and that knowledge from activated sludge-based EBPR approaches cannot be translated to MBBR systems.

Impact of Cardiovascular Factors on Pulse Wave Velocity and Total Vascular Resistance in Different Age Group Patients with Cardiovascular Disorders
Authors: Ghosh Amit , Dharmarajan Abhijith , Swain Prafulla K. , Das Debasish , Verma Poonam , Tripathy Prabhas R.
Published: April 2019

Background:

Pulse Wave Velocity (PWV) is the propagation speed of the wave-induced
along the aorta and arterial tree, each time the heart beats. PWV increases with increased arterial
stiffness, thus establishing it as a reliable prognostic marker for cardiovascular morbidity and mortality.
On the other hand, Total Vascular Resistance (TVR) is the overall resistance offered by systemic
circulation and pulmonary circulation. This resistance needs to be overcome in order to create
the flow of blood through the circulatory system. The goal of this study was to investigate the influence
of different cardiovascular factors on arterial stiffness and vascular resistance in CVD patient
from eastern India population.

Methods:

Total of 782 patients with Cardiovascular Disease (CVD) like hypertension, Ischemic
heart disease, Congestive cardiac failure and peripheral arterial disease were included to evaluate
the cardiovascular hemodynamic and non-hemodynamic parameter by oscillometric method and
investigated those factors on PWV and TVR in subjects of both sexes aged between 15 to 87 years.

Results:

The old age (> 55 years) was found to have greatest impact on PWV as compared with
younger age group. Systolic Blood Pressure (SBP), Heart Rate (HR), augmentation pressure and
Body Surface Area (BSA) had a positive association with the PWV. Augmentation Index and Body
Mass Index (BMI) had a negative impact on the PWV.

Conclusion:

Despite the limitations, like unequal number of male and female participants, wide
variation of the age of the subjects and analyzing association of many factors at a time, our large
and community-based study show individual blood pressure and pulse pressure depending on complex
interaction between large arteries and arterioles. This study sheds light on the relationship between
proximal and distal part (PWV and TVR) of the arterial tree as well as their association with
different hemodynamic and non-hemodynamic parameters.
Ni/x%Nb2O5/Al2O3 Catalysts Prepared via Coprecipitation-Wet Impregnation Method for Methane Steam Reforming
Authors: Gonçalves Juliana F. , Souza Mariana M.V.M.
Published: April 2019

Background:

Hydrogen has been considered the energy source of the future and one of the
processes for its production is the methane steam reforming. The catalyst used industrially is Ni/Al2O3
and the addition of promoter oxides can be an alternative to improve the performance of this catalyst,
which suffers from coke formation and sintering.

Objective:

Evaluate the role of niobia on catalytic activity and stability.

Methods:

Ni/x%Nb2O5/Al2O3 (x = 5, 10 and 20) catalysts were synthesized via coprecipitation-wet impregnation
method and characterized by X-ray fluorescence (XRF), N2 adsorption-desorption, X-ray diffraction
(XRD), temperature- programmed reduction (TPR), temperature-programmed desorption of
ammonia (TPD-NH3), etc. Finally, the catalysts were tested for methane steam reforming reaction.

Results:

All niobia-doped catalysts presented similar values of methane conversion and when comparing
with Ni-Al, the addition of niobia slightly improved the methane conversion. In the stability test at
800oC, all doped and non-doped catalysts did not deactivate during the 24 h of reaction.

Conclusion:

The addition of 10 and 20 wt.% of niobia had a significant promoter effect over Ni/Al2O3
catalyst in terms of activity and stability at 800 oC and the sample with 20 wt.% of niobia presented
lower coke formation.

Published: April 2019

BACKGROUND

Among Latinas and Hispanics (henceforth referred to as Latinas), breast cancer is the most commonly diagnosed cancer and the leading cause of cancer-related deaths. However, few interventions have been developed to meet the needs of Latina women undergoing active treatment for breast cancer.

OBJECTIVE

This paper aims to describe the procedures and methods of My Guide for Breast Cancer Treatment and the plans for conducting a multisite randomized controlled trial to investigate the feasibility and preliminary efficacy of this smartphone-based app for Latina women in active treatment for breast cancer.

METHODS

Study participants will be randomized to the My Guide for Breast Cancer Treatment intervention or the enhanced usual care control condition for 12 weeks. Participants will have access to innovative features such as gamification via virtual awards to reinforce usage and an adaptive section that presents targeted material based on their self-reported concerns and needs. Using a stepped-care approach, intervention participants will also receive telecoaching to enhance their adherence to the app. Study outcomes and intervention targets will be measured at study enrollment (before randomization), 6 and 12 weeks after initial app use. General and disease-specific health-related quality of life (HRQoL) and symptom burden are the study’s primary outcomes, whereas anxiety, depression, fear of cancer recurrence, physical activity, and dietary intake are secondary outcomes.

RESULTS

Recruitment began in August 2019 and is expected to be completed by August 2020. We expect to submit study results for publication by fall 2020.

CONCLUSIONS

My Guide for Breast Cancer Treatment has the potential to improve HRQoL and reduce symptom burden, and increase access to supportive care resources among Latina breast cancer patients.

Hidden Communities of Practice in Social Media Groups: Mixed Methods Study (Preprint)
Authors: Skelton Kara , Evans Retta , LaChenaye Jenna
Published: April 2019

BACKGROUND

Although most US mothers initiate breastfeeding, suboptimal breastfeeding rates still exist. Although breastfeeding is a complex process, social support has been linked with increases in positive breastfeeding outcomes. Recent technological advances, including the development of social networking sites, provide mothers with convenient access to a unique array of audiences from which to seek advice about parenting, including breastfeeding. However, little is known about how the use of the sites—specifically groups centered around breastfeeding—influences breastfeeding knowledge, attitudes, or behaviors.

OBJECTIVE

This mixed methods study aimed to explore utilization of an existing probreastfeeding Facebook group and how utilization influences breastfeeding-related knowledge, attitudes, and behaviors.

METHODS

Participants were recruited online through Facebook wall posts from within the existing group. Mothers aged between 18 and 50 years who were pregnant and intended to breastfeed, were currently breastfeeding, or had recently weaned their infant in the past 3 years were eligible to participate. Participants engaged in online focus group discussions (n=21) and individual interviews (n=12). Inductive content analysis of qualitative data led to the conceptualization and contextualization of a breastfeeding community of practice (COP). Using qualitative results, a quantitative survey was then developed to assess the prevalence of qualities of a COP as well as how COP usage influenced breastfeeding-related attitudes and knowledge. A total of 314 mothers completed the online survey.

RESULTS

Qualitative findings showed an overall sense of community, with subthemes of group trust, interaction, and the promotion of breastfeeding. A majority (287/314, 91.5%) of mothers initiated breastfeeding, with 69.0% (216/314) of mothers reporting exclusive breastfeeding their infant at 6 months. Approximately 98.5% (309/314) of mothers reported that the Facebook group captured and stored knowledge; therefore, information could be easily accessed and applied. In addition, 96.2% (302/317) of mothers reported that the Facebook group motivated them to share breastfeeding-related knowledge.

CONCLUSIONS

The results suggest that this existing probreastfeeding Facebook group exhibits characteristics of an online COP, which was organically formed. Utilization of the Facebook group, in the context of an online COP, could be beneficial in impacting breastfeeding-related knowledge, attitudes, and behaviors. However, further examination and exploration of breastfeeding COPs, including using this type of model as a method of lactation support or as a telemedicine framework, is a clear need.

Authors: Burchartz Alexander , Manz Kristin , Anedda Bastian , Niessner Claudia , Oriwol Doris , Schmidt Steffen CE , Woll Alexander
Published: April 2019

BACKGROUND

Currently, no nationwide objective physical activity data exists for children and adolescents living in Germany. The German Health Interview and Examination Survey for Children and Adolescents (KiGGS) and the Motorik-Modul study (MoMo) is a national cohort study that has incorporated accelerometers in its most recent data collection wave (wave 2, since 2014). This wave 2 marks the first nationwide collection of objective data on the physical activity of children and adolescents living in Germany.

OBJECTIVE

The purpose of this protocol is to describe the methods used in the KiGGS and MoMo study to capture the intensity, frequency, and duration of physical activity with accelerometers.

METHODS

Participants (N=11,003, aged 6 to 31 years) were instructed to wear an ActiGraph GT3X+ or wGT3X-BT accelerometer laterally on the right hip. Accelerometers were worn on consecutive days during waking hours, including at least 4 valid weekdays and 1 weekend day (wear time >8 hours) in the evaluation. A nonwear time protocol was also implemented.

RESULTS

Data collection was completed by October 2017. Data harmonization took place in 2018. The first accelerometer results from this wave were published in 2019, and detailed analyses are ready to be submitted in 2020.

CONCLUSIONS

This study protocol provides an overview of technical details and basic choices when using accelerometers in large-scale epidemiological studies. At the same time, the restrictions imposed by the specified filters and the evaluation routines must be taken into account.

Evaluation of the Universal Prevention Program Klasse2000 in Fourth Grade Primary School Children: Protocol for a Propensity Score-Matching Approach (Preprint)
Authors: Kliem Sören , Krieg Yvonne , Lohmann Anna , Mößle Thomas
Published: April 2019

BACKGROUND

Klasse2000 is the most widely adopted school-based prevention program in Germany. It addresses health promotion, addiction, and violence prevention in primary schools. As a universal prevention program, it has reached more than 1.4 million German children in the past 25 years.

OBJECTIVE

The effectiveness of Klasse2000 will be evaluated with a large representative survey among students. Students who have participated in the prevention program (intervention group) will be compared with students who did not participate (control group). The comparison will cover the following outcome domains: well-being, self-esteem, emotion regulation, food habits, behavioral problems, and school and classroom atmosphere. Furthermore, victimization and perpetration regarding bullying, alcohol consumption, smoking, and media consumption are assessed.

METHODS

To control for potential group differences, treatment effects will be estimated using propensity score-matching, which matches students from the intervention and control groups based on an identical propensity score or a propensity score that does not differ by more than a previously defined distance. The treatment effect will then be estimated in the matched sample taking the matching process into account.

RESULTS

Enrollment of schools began in March 2017. A total of 6376 students participated in the survey (n=4005 in control group; n=2371 in Klasse2000). The parent survey was returned by 52.13% (3324/6376) of parents. Results are expected in mid-2020.

CONCLUSIONS

The results on the effectiveness of the Klasse2000 prevention program will form an empirical basis for legitimizing universal prevention programs and for planning future prevention approaches.

Understanding and Preventing Health Concerns About Emerging Mobile Health Technologies (Preprint)
Authors: Materia Frank T , Faasse Kate , Smyth Joshua M
Published: April 2019

UNSTRUCTURED

New technologies and innovations have often improved population well-being and societal function; however, these are also often initially accompanied by worry and fear. In some cases, such worries can impede, or even prevent entirely, the adoption of the technology. Mobile health (mHealth), a discipline broadly focused on employing ambulatory technologies to improve the affordability, reach, and effectiveness of health promotion and clinical intervention approaches, offers new innovations and opportunities. Despite emerging evidence supporting mHealth efficacy (eg, for improving health outcomes), some individuals have concerns about mHealth technology that may impede scalability, efficacy, and, ultimately, the public health benefits of mHealth. We present a review and conceptual framework to examine these issues, focusing on three overarching themes: biophysiological, psychological, and societal concerns. There are features of mHealth that lead to worries about the potential negative effects on an individual’s health (eg, due to exposure to electromagnetic or radio waves), despite evidence supporting the safety of these technologies. When present, such beliefs can lead to worry that gives rise to the experience of unpleasant and concerning physical symptoms—the nocebo effect. This may represent an important implementational barrier because of apprehension toward beneficial mHealth products (or features thereof, such as wireless charging, wearable or implantable sensors, etc) and may also have broader ramifications (eg, leading to economic, governmental, and legislative actions). In addition to reviewing evidence on these points, we provide a broad three-step model of implementation research in mHealth that focuses on understanding and preventing health concerns to facilitate the safe and effective scalability of mHealth (and that may be generalizable and applied to similar technologies): (1) evaluating and better discerning public perceptions and misperceptions (and how these may differ between populations), (2) developing theory-based public health communication strategies regarding the safety of mHealth, and (3) disseminating this messaging using evidence-based methods. Collectively, these steps converge on reviewing evidence regarding the potential role of worry and nocebo in mHealth and providing a model for understanding and changing attitudes and preventing unfounded negative perceptions related to mHealth technology.
A Brief Mobile-Augmented Suicide Prevention Intervention for People With Psychotic Disorders in Transition From Acute to Ongoing Care: Protocol for a Pilot Trial (Preprint)
Authors: Depp Colin , Ehret Blaire , Villa Jennifer , Perivoliotis Dimitri , Granholm Eric
Published: April 2019

BACKGROUND

People with serious mental illnesses (SMIs) are at exceptionally high risk for lifetime suicidal ideation and behavior compared with the general population. The transition period between urgent evaluation and ongoing care could provide an important setting for brief suicide-specific interventions for SMIs. To address this concern, this trial, SafeTy and Recovery Therapy (START), involves a brief suicide-specific cognitive behavioral intervention for SMIs that is augmented with mobile phone interactions.

OBJECTIVE

The primary aim of this pilot trial is to evaluate the feasibility, acceptability, and preliminary effectiveness of the intervention.

METHODS

A 6-month pilot trial with 70 participants with a diagnosis of bipolar disorder, schizophrenia or schizoaffective disorder, and current active suicidal ideation were randomized to START or START with mobile augmentation. START consists of 4 weekly sessions addressing early warning signs and triggers, symptoms influencing suicidal thinking, and social relationships. Recovery planning is followed by biweekly telephone coaching. START with mobile augmentation includes personalized automated cognitive behavioral therapy scripts that build from in-person content. Participants were evaluated at baseline, 4 weeks (end of in-person sessions), 12 weeks (end of telephone coaching), and 24 weeks. In addition to providing point estimates of feasibility and acceptability, the primary outcome of the trial was the change in severity of suicidal ideation as measured with the Scale for Suicide Ideation (SSI) and secondary outcome included the rate of outpatient engagement.

RESULTS

The trial is ongoing. Feasibility and acceptability across conditions will be assessed using t tests or Mann-Whitney tests or chi-square tests. The reduction of SSI over time will be assessed using hierarchical linear models.

CONCLUSIONS

The design considerations and results of this trial may be informative for adapted suicide prevention in psychotic disorders in applied community settings.

Optimizing the Impact of Public-Academic Partnerships in Fostering Policymakers’ Use of Research Evidence: Proposal to Test a Conceptual Framework (Preprint)
Authors: Kang-Yi Christina D
Published: April 2019

BACKGROUND

Previous research has reported that public-academic partnerships (PAPs) can effectively promote PAP leaders’ use of research evidence in improving youth outcomes. However, the existing literature has not yet clarified whether and how PAP leaders’ use of research evidence evolves along the PAP life cycle and whether PAP partners’ concordant perceptions of usefulness of their PAP has an impact on PAP leaders’ use of research evidence. Developing a conceptual framework that recognizes the PAP life cycle and empirically identifying contexts and mechanisms of PAPs that promote PAP leaders’ use of research evidence from the PAP life cycle perspective are imperative to guide researchers and policymakers to successfully lead PAPs and foster policymakers’ use of research evidence for improving youth outcomes.

OBJECTIVE

Utilizing an integrated framework of organizational life cycle perspective, a social partnership perspective, and a realist evaluation, this study examines the extent to which PAP development and PAP leaders’ use of research evidence can be characterized into life cycle stages and identifies PAP contexts and mechanisms that explain the progress of PAPs and PAP leaders’ use of research evidence through life cycle stages.

METHODS

Recruiting PAPs across the United States that aim to improve mental health and promote well-being of youth aged 12-25 years, the study conducts a document analysis and an online survey of PAPs to inform policymakers and academic researchers on the contexts and mechanisms to increase PAP sustainability and promote policymakers’ use of research evidence in improving youth outcomes.

RESULTS

Fifty-three PAPs that meet the recruitment criteria have been identified, and document review of PAPs and participant recruitment for the online survey of PAP experience have been conducted.

CONCLUSIONS

This paper will help policymakers and researchers gain a deeper knowledge of the contexts and mechanisms for each PAP life cycle stage in order to optimize PAP leaders’ use of research evidence in achieving positive youth outcomes.

Collective Empowerment in Online Health Communities: Scale Development and Empirical Validation (Preprint)
Authors: Atanasova Sara , Petric Gregor
Published: April 2019

BACKGROUND

The role of online health communities (OHCs) in patient empowerment is growing and has been increasingly studied in recent years. Research has focused primarily on individualistic conception of patients’ empowerment, with much less attention paid to the role of OHCs in the development of patients’ collective empowerment. Although OHCs have immense potential for empowerment that goes beyond the individual, the concept and scale of collective empowerment in OHCs have not yet been developed or validated.

OBJECTIVE

This study aimed to develop an instrument for measuring collective empowerment in online health communities (CE-OHC) and to test its quality by investigating its factorial structure, reliability, construct validity, and predictive validity.

METHODS

The CE-OHC scale was developed according to a strict methodology for developing valid and reliable scales. An initial set of 20 items was first tested in the pilot study conducted in 2016 using a sample of 280 registered users of Slovenia’s largest OHC. A refined version with 11 items was tested in the main study conducted in 2018 on a random sample of 30,000 registered users of the same OHC. The final sample comprised 784 users. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to investigate the factorial structure, discriminant validity, and convergent validity of the scale. Cronbach alpha coefficient was used to determine the CE-OHC scale’s internal consistency. To establish the predictive validity, ordinary least squares regression was performed to test the role of CE-OHC in users’ civic participation.

RESULTS

The EFA resulted in a two-factor solution, and the two factors—knowledge of resources and resource mobilization for collective action—together explain 63.8% of the variance. The second-order CFA demonstrated a good fit to the data (root mean square error of approximation=0.07) and the scale had a good internal consistency (alpha=.86). Although evidence of the scale’s convergent validity was partially provided, discriminant validity of the scale remained unconfirmed. Overall, CE-OHC was confirmed to be a predictor of users’ civic participation, but the influence was somewhat weak and inconsistent across two subscales.

CONCLUSIONS

The proposed CE-OHC scale is a reliable and relatively valid instrument and serves as a good baseline to advance the measurement of collective empowerment in OHC contexts. This is the first scale developed for this purpose, and future research should focus on the development of a clear nomological network of the collective empowerment construct in relation to the OHC settings.

Jaccard’s similarity index was utilized to identify terms most frequently co-occurring with each other. Latent Dirichlet Allocation was used for classifying papers into corresponding topics.

RESULTS

The number of studies applying AI to cancer during 1991-2018 has been grown with 3,555 papers covering therapeutics, capacities, and factors associated with outcomes. Topics with the highest volumes of publications include 1) Machine learning, 2) Comparative Effectiveness Evaluation of AI-assisted medical therapies, 3) AI-based Prediction. Noticeably, this classification has revealed topics examining the incremental effectiveness of AI applications, the quality of life and functioning of patients receiving these innovations. The growing research productivity and expansion of multidisciplinary approaches, largely driven by machine learning, artificial neutral network, and artificial intelligence in various clinical practices.

CONCLUSIONS

The research landscapes show that the development of AI in cancer is focused not only on improving prediction in cancer screening and AI-assisted therapeutics, but also other corresponding areas such as Precision and Personalized Medicine and patient-reported outcomes.
User-Driven Guidelines for Technology-Enabled Culinary Nutrition Education Program to Support Engaged Overweight and Obese Adolescents (Preprint)

Published: April 2019

BACKGROUND

Childhood overweight and obesity are major health challenges in the US. One of the recommendations to combat obesity is to maintain a healthy diet, which is often best supported by eating home cooked meals to control cooking methods, ingredients, and portions. Diet control through home cooking is challenged due to the decline of culinary skills in the population and a paucity of effective culinary nutrition education programs (CNE). Providing technology-enabled CNE (CNE-tech) to overweight and obese adolescents can equip them with life skills that can assist them in the future. Such skills can facilitate saving money, eating healthier, and creating social environments. In addition, CNE builds cooking confidence and food literacy that in turn can build adolescent self-efficacy, particularly towards managing their health behaviors.

OBJECTIVE

In this study, we aim to inform functionalities, design requirements, and the context of use for CNE-tech that could enhance overweight and obese adolescents’ healthy food literacy, cooking confidence, and general self-efficacy regarding self-management to ultimately, promote healthy lifestyle management.

METHODS

The design science study was completed in two distinct phases engaging overweight and obese adolescents, parents of overweight and obese adolescents, and providers that treat adolescents with these conditions. Phase 2, our primary source of data, involved user-centered design methods including: a) early stage prototype usability analysis, b) semi-structured interviews with 70 overweight or obese adolescents engaged in a healthy behavior program and c) semi-structured interviews with 10 healthcare providers. Data was analyzed using a constant comparison method to identify functionalities, design requirements, and inform the context of use of CNE-tech.

RESULTS

Data revealed specific desired functionalities for the CNE-tech related to cooking skill building, populated healthy recipes database, suggesting healthy alternatives, supports to construct a healthy plate, and the ability to share healthy recipes and cooking accomplishments. Moreover, adolescents provided design requirements pertaining to presentation (e.g., vivid colors, semi-realistic images, cooking sounds), use of multimedia, and gaming. Data further revealed contextual factors, such as shared experiences with family members and enhanced continued use.

CONCLUSIONS

We demonstrate the potentiality of creating CNE-tech that could effectively lead to better self-care and induce sustainable behavioral change as it facilitates skill building, self-efficacy, and a pathway that enables overweight and obese adolescents to influence cooking habits in their family home and future dwellings. Our CNE-tech proposed solution aligns with the goals of overweight and obese adolescents and also reflects existing theories about behavioral change.

BACKGROUND

The public’s understanding of science can be influential in a wide range of areas related to public health, including policy making and self-care. Through the digital and social media ecosystem, health scientists play a growing role in public science communication (SC).

OBJECTIVE

This review aimed to (1) synthesize the literature on SC initiated by health scientists targeting the public in the digital and social media ecosystem and (2) describe the SC strategies and communication channels used.

METHODS

This scoping review was based on the Joanna Briggs Institute Methodological Framework. A systematic search was performed in 6 databases (January 2000 to April 2018). Title and abstract screening, full-text review, data charting, and critical appraisal were performed independently by two review authors. Data regarding included studies and communication channels were synthesized descriptively. A typology of SC strategies was developed using a qualitative and inductive method of data synthesis.

RESULTS

Among 960 unique publications identified, 18 met inclusion criteria. A third of publications scored good quality (6/18, 33%), half scored moderate quality (9/18, 50%), and less than a fifth scored low quality (3/18, 16%). Overall, 75 SC strategies used by health scientists were identified. These were grouped into 9 types: content, credibility, engagement, intention, linguistics, planification, presentation, social exchange, and statistics. A total of 5 types of communication channels were identified: social networking platforms (eg, Twitter), content-sharing platforms (eg, YouTube), digital research communities (eg, ResearchGate), personal blogs and websites (eg, WordPress), and social news aggregation and discussion platforms (eg, Reddit).

CONCLUSIONS

Evidence suggests that multiple types of SC strategies and communication channels are used by health scientists concurrently. Few empirical studies have been conducted on SC by health scientists in the digital and social media ecosystem. Future studies should examine the appropriateness and effectiveness of SC strategies for improving public health–related outcomes and identify the barriers, facilitators, and ethical considerations inherent to the involvement of health scientists in the digital and social media ecosystem.
Impact of Training of Primary Health Care Centers’ Vaccinators on Immunization Session Practices in Wasit Governorate, Iraq: Interventional Study (Preprint)
Authors: Amily Ali Sadiq , Lami Faris , Khader Yousef
Published: April 2019

BACKGROUND

Immunization averts more than 2.5 million deaths of children annually. The World Health Organization (WHO) and the United Nations Children’s Fund estimates of immunization coverage in Iraq in 2015 revealed a 58% coverage for the third dose of the diphtheria-tetanus-pertussis vaccine and a 57% coverage for the measles vaccine. High-quality immunization session practices (ISPs) can ensure safer, more effective vaccination and higher coverage rates.

OBJECTIVE

The goal of this study was to assess the impact of training of primary health care centers’ (PHCs) vaccinators on the quality of ISPs.

METHODS

This was an interventional study conducted on 10 (18%) PHCs in Wasit Governorate. Two PHCs were randomly selected from each health district. ISPs were assessed by direct on-job observation, using modified WHO immunization session checklists. Findings were grouped into seven domains: vaccine and diluent management, cold chain management, session equipment, registration, communication, vaccine preparation and administration, and waste management. The vaccinators were enrolled in a one-day training session using the WHO module, “Managing an Immunization Session”, and one month later a second assessment was conducted using the same tools and techniques. We then calculated the median differences of the domains' scores.

RESULTS

A total of 42 vaccinators were trained, with 25 (60%) of them having graduated from technical health institutes, but only 15 (36%) having had previous training on standard ISPs. Following training, a significant improvement was noticed in three domains: vaccines and diluents management (P=.01), cold chain management (P=.01) and vaccine preparation and administration (P=.02).

CONCLUSIONS

The training of the PHCs' vaccinators for a single day was effective in improving some ISPs. We would recommend using this training module, or a more in-depth one, for other PHCs to improve utilization of immunization services.
