Effectiveness of Integrated Social and Behavior Change Communication Interventions in Mass Drug Administration Campaigns in Enhancing Knowledge, Perceptions, and Preventive Practices for Neglected Tropical Diseases in Jimma.

Background: Despite control efforts, including mass drug administration (MDA), neglected tropical diseases (NTDs) continue to pose a significant public health threat, particularly in rural Ethiopia. Integrating social and behavior change communication (SBCC) into MDA is essential for success. This study aimed to evaluate the effectiveness of tailored SBCC integrated into MDA campaigns to enhance community knowledge, perception, and preventive behaviors regarding targeted NTDs in the Jimma, Ethiopia. Methods: A community-based study was conducted using a pre-test post-test design. A multistage sampling technique was employed for surveys, while for qualitative insights, purposive sampling was employed. SBCC interventions tailored to local needs were implemented. Changes in knowledge, perception, and practices were evaluated using Cohen's d. Additionally, a score for key outcome variables comparisons were made to examine variations based on socio-demographic factors, employing suitable statistical tests. Qualitative data were analyzed thematically using Atlas.ti 7.1.5. Results: The prevalence of SBCC exposure was 88.8%. The intervention had a more significant impact on improving knowledge and preventive practices related to Onchocerciasis (OC) compared to Soil-transmitted helminthes (STH). Specifically, most OC outcomes showed moderate to large effect sizes. In contrast, the effect on STH was more limited, with only knowledge of consequences improving moderately and preventive practices showing a small effect size. The mean score for OC preventive practices varied by educational level and sex, while the median score for STH perception varied among educational level and marital status. Additionally, score variation was observed across districts for all key outcome variables. Conclusion: The majority of the population was exposed to SBCC resulting in improvements in knowledge, perception, and preventive behaviors regarding OC and knowledge of consequences of STH and its prevention behavior. This highlights the importance of incorporating well-designed SBCC activities in to MDA campaigns to optimize the control and eventual elimination of targeted NTDs.

Diet Quality Among Mothers and Children in India: Roles of Social and Behavior Change Communication and Nutrition-Sensitive Social Protection Programs.

BACKGROUND: Limited evidence exists on determinants of maternal and child diet quality. OBJECTIVES: This study examined the role of social and behavior change communication (SBCC) and nutrition-sensitive social protection (NSSP) programs on maternal and child diet quality. METHODS: Data were from cross-sectional phone survey on 6627 Indian mothers that took place in late 2021. The Diet Quality Questionnaire (DQQ) was used to measure maternal and child diet quality, including minimum dietary diversity (MDD), dietary diversity scores (DDSs), noncommunicable disease (NCD)-protect and NCD-risk scores, adherence to dietary guidelines (All-5 and India-All-6), and unhealthy child feeding. Multivariate regression models were used to explore the association between diet indicators and coverage of SBCC and NSSP programs. RESULTS: Maternal and child diet quality was suboptimal, with more mothers (57%) achieving MDD than children (23%). SBCC was positively associated with healthy food consumption in children (odds ratio [OR]: 2.14 for MDD; ß: 0.60 for DDS and 0.54 for NCD-protect) and mothers (ß: 0.38 for DDS and 0.43 for NCD-protect). Cash transfers were associated with healthier diets in mothers (OR: 1.45 for MDD, 1.86 for All-5, and 2.14 for India-All-6; ß: 0.43 for DDS and 0.26 for NCD-protect), but less associations noted for children (ß: 0.14 for NCD-protect). Receiving food was associated not only with healthier diets in mothers (OR: 1.47 for MDD; ß: 0.27 for DDS and 0.33 for NCD-protect) and children (ß: 0.19 for DDS and 0.15 for NCD-protect) but also with unhealthy food in children (OR: 1.34). Exposure to multiple programs showed stronger associations with diet quality. CONCLUSIONS: SBCC has greater positive impact on child feeding than food and cash transfers, while cash has a stronger association with improved maternal diets. Food and cash are also associated with unhealthy food consumption. Our study underscores the importance of interventions that combine education, resource provision, and targeted support to promote maternal and child diet quality.

Effect of social and behavioral change interventions on minimum dietary diversity among pregnant women and associated socio-economic inequality in Rajasthan, India.

BACKGROUND: Maternal dietary diversity is a key to improving the birth and child health outcomes. Besides socio-economic factors, the nutrition specific program- Social and Behavioural Change Communication (SBCC) interventions aimed to improve maternal dietary diversity has varied levels of impact on the socio-economic groups in poor resource setups. OBJECTIVE: To measure the factors associated with the minimum dietary diversity (MDD) among pregnant women in selected districts of Rajasthan with special emphasis on the SBCC components. Additionally, it measures the socio-economic gaps in the behaviour of consumption of diversified diet during pregnancy. METHODS: Data from a cross sectional survey of 6848 pregnant women, who have received a continuous SBCC counselling and registered under a state introduced conditional cash transfer program, during May to June, 2023, in five intervention districts -Banswara, Baran, Dunagrpur, Pratapgarh and Udaipur in Rajasthan was used. A 24 h recall based food consumption behaviour has been gathered to measure the MDD of pregnant women. Study has used descriptive statistics, multivariate regressions, and multivariate decomposition analysis to address the research objectives. RESULTS: Study finds that only 55.2% of pregnant women are consuming diverse diet in the study duration with mean dietary diversity score is 4.8 (+/- 1.5). Logistic regression finds that SBCC components such as frontline workers (aOR = 1.3, CI: 1.1-1.4), community motivators (aOR = 1.9, CI: 1.7-2.1), and participation in MCHND (aOR = 1.0, CI: 0.9-1.2) have significant and higher likelihood on consumption of MDD food on previous day. A higher education and belonging from richer wealth quintile also show higher association for consumption of MDD. Multivariate decomposition shows, among richest and poorest wealth categories there is 19% point difference (58% difference due to coefficient vs. 42% difference due to composition) in MDD consumption. This is positively contributed by the caste and educational categories of women. CONCLUSION: Despite a predominant vegetarian diet consuming population, better maternal dietary diversity was observed among those exposed to higher dose of SBCC intervention package. Educational status and caste of the respondent were significantly associated with minimum dietary diversity and contributed to the socio-economic inequality highlighting the importance of tailored and sustained SBCC interventions.

Social and behavior change communication competency among front-line healthcare system actors in Ethiopia: a cross-sectional study.

INTRODUCTION: Social and Behavior Change Communication (SBCC) plays a critical role in improving behavior and health outcomes across the continuum of healthcare. Failing to implement tailored SBCC strategies continues to pose a risk of ill health, increase disease burden, and impact the quality life of people. In Ethiopia, front-line healthcare system actors' knowledge and skills about SBCC have not been rigorously assessed. Thus, the current study aimed to assess healthcare system actors' competencies in designing, implementing, monitoring, and evaluating SBCC interventions in Ethiopia. METHODS: A cross-sectional study was conducted between 01 August and 31 October, 2020. Five hundred twenty-eight frontline healthcare system actors in SBCC in Ethiopia were included using simple random sampling technique. Data was collected using a self-administered structured questionnaire adopted from Communication for Change; SBCC capacity assessment tool. Descriptive analysis frequencies, percentages, mean, median, standard deviation (SD), interquartile range (IQR) were employed. Besides correlations and linear regression with robust standard errors were carried out. A 95% confidence interval and a p-value of less than 0.05 were used to declare significant statistical association. RESULTS: A total of 488 frontline workers participated in the study, with a response rate of 92.4%. The mean SBCC knowledge score was 13.2 ± standard deviation (SD) 3.99 and 59.2% scored below 60% of the expected maximum score. The standard mean score of overall skill in SBCC intervention was 2.36 (SD ± 0.98) and 52.6% of them scored below mean score. The SBCC knowledge was significantly predicted by the service year and the regional variation. On the other hand, SBCC skills was significantly predicted by sex, service year, profession, regional variation, and SBCC knowledge. The regional variation was the main predictor of both knowledge and skill on SBCC. The regression models explained 23.1% and 50.2% of the variance in knowledge and skill of SBCC, respectively. CONCLUSION: Front-line healthcare system actors in Ethiopia has low knowledge and skills in SBCC. Variations in SBCC knowledge and skill were observed based on demographic and professionals experience related characteristics. Hence, continuous capacity building activities need to be given to frontline healthcare system actors to enhance their knowledge and skill on SBCC program and achieve the intended health results.

COVID-19 Prevention Behaviours and Vaccine Acceptability, and Their Association with a Behaviour Change Campaign in Somalia: Analysis of a Longitudinal Cohort.

Somalia experienced its first wave of COVID-19 infections in March 2020 and has experienced fluctuating infection levels since. Longitudinal data on suspected cases of COVID-19, attitudes, and behaviours were collected by telephone interviews of cash-transfer programme beneficiaries from June 2020-April 2021. A multi-media Social and Behaviour Change Communication (SBCC) campaign was designed and implemented from February 2021 to May 2021. Between the end of the first wave and the onset of the second the perceived threat from COVID-19 increased, with the proportion of respondents viewing it as a major threat increasing from 46% to 70% (p = 0.021). Use of face coverings increased by 24% (p < 0.001) and hand shaking and hugging for social greeting decreased, with 17% and 23% more people abstaining from these practices (p = 0.001). A combined preventative behaviour score (PB-Score) increased by 1.3 points (p < 0.0001) with a higher score in female respondents (p < 0.0001). During wave 2, vaccine acceptance was reported by 69.9% (95% CI 64.9, 74.5), overall. Acceptance decreased with increasing age (p = 0.009) and was higher in males (75.5%) than females (67.0%) (p = 0.015). Awareness of the SBCC campaign was widespread with each of the 3 key campaign slogans having been heard by at least 67% of respondents. Awareness of 2 specific campaign slogans was independently associated with an increased use of face coverings (aOR 2.31; p < 0.0001) and vaccine acceptance (aOR 2.36; p < 0.0001). Respondents reported receiving information on the pandemic from a wide range of sources with mobile phones and radio the most common. Trust in different sources ranged widely.

The Impact of a Large-Scale Social and Behavior Change Communication Intervention in the Lake Zone Region of Tanzania on Knowledge, Attitudes, and Practices Related to Stunting Prevention.

BACKGROUND: Large-scale social and behavioral change communication (SBCC) approaches can be beneficial to achieve improvements in knowledge, attitudes, and practices (KAP). Addressing Stunting in Tanzania Early (ASTUTE) included a significant SBCC component and targeted precursors to stunting including KAP related to maternal and child health, antenatal care, WASH, childhood development, and male involvement. METHODS: Baseline, midline, and endline surveys were conducted for a total of 14,996 female caregivers and 6726 male heads of household in the Lake Zone region of Tanzania. Regression analyses were used to estimate differences in KAP from baseline to midline and endline. RESULTS: Women's knowledge of handwashing and infant/child feeding practices, and attitudes related to male involvement, consistently improved from baseline to midline and baseline to endline. Women's practices related to antenatal care, breastfeeding, and early child development improved from baseline to midline and baseline to endline. Improvements in KAP among male heads of household were varied across indicators with consistent improvement in practices related to child feeding practices from baseline to midline and baseline to endline. CONCLUSION: Many changes in KAP were observed from baseline to midline and baseline to endline and corresponded with SBCC programming in the region. These results provide support for the value of large SBCC interventions. Public health efforts in settings such as Tanzania may benefit from adopting these approaches.

Acceptability of peer learning and education approach on malaria prevention (PLEA-malaria) through primary schools communities in rural Ethiopia: peer educators' perspectives.

BACKGROUND: Evidence on peer educators' experiences of implementing the school-based educational interventions on malaria prevention would be used as inputs for malaria eliminating efforts. This study explored the acceptability of the school-based peer-learning and education approach on malaria prevention (PLEA-malaria) among peer educators in Ethiopia. METHODS: This process evaluation study was aimed to examine the success of the school-based PLEA-malaria that was implemented in 75 primary schools in Jimma from 2017 to 2019. A mixed research method was employed to collect post-intervention data from 404 peer educators and key stakeholders. Data were collected using a structured questionnaire and interview guide. Multivariable linear regression modelling was performed using SPSS software version 26.0. Atlas ti 7.5 for windows was used to analyse the qualitative data. The result was presented by triangulating the findings of the qualitative and quantitative methods. RESULTS: The mean score (M, range = R) of acceptability of PLEA-malaria was (M = 20.20, R = 6-30). The regression modelling showed that age; (ß = 0.264, 95% CI 0.266 to 0.632), GPA; (ß = 0.106, 95% CI 0.008 to 0.074), parental readiness for malaria education; (ß = 0.184, 95% CI 0.711 to 2.130), frequency of peer education; (ß = 0.232, 95% CI 1.087 to 2.514) and team spirit; (ß = 0.141, 95% CI 0.027 to 0.177) were positively associated with the acceptability while this relationship was negative for the number of ITN in the household; (ß = - 0.111, 95% CI - 1.182 to -0.13) and frequency of parent-student communication; (ß = - 0.149, 95% CI - 1.201 to - 0.293). The qualitative study identified facilitators of PLEA-malaria (e.g. team formation process, outcome efficacy, presence of schools' structures, schools priority, and support) and barriers (e.g. low commitments, threat appraisal, response efficacy, and PLEA-malaria implementation gaps). CONCLUSION: The results suggested that the acceptability of the school-based PLEA-malaria was higher implying the strategy is promising in promoting malaria prevention in primary schools. Considering factors related to personal, access to malaria preventive services, school system, and social support in education and behaviour change interventions would be important to improve the acceptability. The relationship about how an improvement in the level of acceptability would in turn influences malaria preventive behaviours among the students should be investigated.

Acceptability and feasibility of the school-engaged social and behavior change communication approach on malaria prevention in Ethiopia: implications for engagement, empowerment, and retention (EER) of education sectors in malaria elimination efforts.

BACKGROUND: Evidence on process outcomes such as acceptability, and feasibility of behavior change communication interventions are important in program evaluation to understand how, and why such a program works. However; documented evidence on the issue is not available as far as the social and behavior change communication (SBCC) on malaria is concerned. Enrolling the frontline providers this study measured the acceptability and feasibility of the school-engaged SBCC strategy on malaria prevention in malaria-endemic settings of Ethiopia. METHODS: A school-engaged SBCC strategy involving various communication and capacity-building interventions aimed to advance malaria preventive practices in primary schools in Jimma were implemented from 2017 to 2019. A cross-sectional study was conducted with 205 key stakeholders at the end of the intervention. Both acceptability and feasibility were measured using standardized tools. Data were collected using a structured questionnaire and filled by the study participants. The SPSS version 26 was used to analyze the data. Multivariate general linear modeling was performed to identify the predictors of acceptability and feasibility of the program. P-value < 5% was considered to decide statistical significance. RESULTS: The result showed the mean scores (M, range = R) of acceptability and feasibility of the program were (M = 25.63, R = 6 to 30) and (M = 19.35, R = 5 to 25) respectively. The multivariate linear modeling showed acceptability was affected by self-efficacy; (ß = 0.438, P < 0.001), community support; (ß = 0.417, P < 0.001), school climate; (ß = - 0.16; P = 0.003), perceived malaria threat; (ß = 0.40, P < 0.001) and knowledge; (ß = 0.229, P = 0.013). Similarly, feasibility was influenced by self-efficacy; (ß = 0.352, P < 0.001), community support; (ß = 0.591, P < 0.001), school climate; (ß = - 0.099, P-value < 0.030) and perceived malaria threat; (ß = 0.172, P = 0.002). CONCLUSION: With a considerably high level of acceptability, the school-engaged SBCC strategy to enhance malaria preventive practices seems feasible. The SBCC strategy targeting personal factors such as malaria threat perceptions, knowledge and skills on the program, and contextual factors that include school social climate and community support would be fruitful to facilitate the implementation of the program. The result implicates the benefit of intensifying such a strategy to engage, empower, and retain the education sectors in malaria elimination efforts and beyond.

Teachers' perspective on implementation of menstrual hygiene management and puberty education in a pilot study in Bangladeshi schools.

OBJECTIVE: To assess the perspectives of Bangladeshi teachers on the feasibility of delivery and potential for long-term sustainability of puberty and menstruation education in urban and rural schools. METHOD: We developed a multi-module puberty and menstrual hygiene management education curriculum that teachers piloted for six months in four urban and rural government and private schools in Bangladesh. We conducted monthly assessments during piloting, discussion for manual revision and four group discussions with 20 participating teachers to understand perceived benefits, barriers, and sustainability of puberty and menstruation education among school children. RESULTS: Teachers acknowledged the importance of school-based puberty and menstruation education to improve students' perception and preparedness. They found that the training and instructors' manual they received were useful tools for effectively communicating with students. Teachers noted school and community pressure to de-emphasize educational content not included on nationally standardized examinations, and insufficient time and pre-service training for teaching sensitive topics served as barriers to implementing the pilot curriculum. CONCLUSION: Pressure from school authorities and community may hinder the successful long-term delivery of school-based puberty and menstruation education programs that are external to the national curriculum. Our findings indicate that feasibly and sustainably improving education on these topics in Bangladeshi classrooms should be achieved through 1) revision of the current national curriculum to incorporate more comprehensive puberty and menstruation information including its physiology, management, and social context, 2) adequate training and support for teachers to deliver the content, and 3) incorporation of puberty and menstruation content into students' national examinations which may better ensure teachers are given the tools and opportunity to prioritize teaching this content.

Perceived sustainability of the school-based social and behavior change communication (SBCC) approach on malaria prevention in rural Ethiopia: stakeholders' perspectives.

BACKGROUND: Evidence on what makes the school-engaged social and behavior change communication (SBCC) interventions on malaria prevention more sustainable are limited in literature partly due to its recent emergence. Enrolling the key stakeholders, this study explored the perceived sustainability of the SBCC interventions on malaria prevention through primary school communities in rural Ethiopia. METHODS: The SBCC interventions were implemented from 2017 to 2019 in 75 primary schools and villages in rural Jimma to promote malaria preventive practices. As a part of program evaluation, this study employed a mixed-method to collect qualitative and quantitative data from 205 stakeholders following the end of the program. Data were collected using interview guides and structured questionnaires. The SPSS version 26 and Atlas ti7.1 software were used to analyze the data. Multivariable linear regression modeling was used to identify predictors of the perceived sustainability of the program (SOP). RESULTS: The mean score of SOP was 25.93 (SD = 4.32; range 6-30). Multivariable linear regression modeling showed that the perceived risk to malaria (ß = 0.150; P = 0.029), self-efficacy (ß = 0.192; P = 0.003), and perceived fidelity of implementation (ß = 0.292; P = 0.000) and degree of adoption (ß = 0.286; P = 0.000) were positively predicted the perceived SOP. The qualitative result identified various barriers and opportunities to sustaining the program that summarized under three themes which include perceptions about the quality of program delivery (e.g inadequate involvement of stakeholders and staffs, concerns over short project life, immature sustainability efforts), school settings (e.g schools' malaria priority, schools' climate and quality of coaching) and the outer settings (e.g existing structures in the health and education systems). CONCLUSION: The study identified key predictive variables such as stakeholders' perceived risk to malaria, self-efficacy, perceived fidelity of implementation and degree of adoption that could help to improve the sustainment of the school-based SBCC approach on malaria prevention and control. Further longitudinal study should be conducted to examine the rate of decline in program components over time and how improved sustainability would contribute to the effectiveness on malaria preventive behaviors among students.

Effectiveness of the school-based social and behaviour change communication interventions on insecticide-treated nets utilization among primary school children in rural Ethiopia: a controlled quasi-experimental design.

BACKGROUND: School-based behaviour change communication interventions could help to achieve behavioural changes in the school and enhance the enrollment of the students and teachers as health messengers to local communities. Evidence on the impacts of the school-engaged malaria preventive interventions are limited as far as the social and behaviour change communication (SBCC) is concerned. This study examined the effectiveness of the school-based SBCC approach on insecticide-treated nets (ITNs) utilization among primary school students in malaria-endemic settings of Ethiopia. METHODS: Various participatory, educational, and communication interventions were implemented from 2017 to 2019 in 75 primary schools and respective villages in Jimma to promote malaria preventive practices. A quasi-experimental design was conducted with randomly selected 798 students (i.e. 399 intervention and 399 control groups). Data were collected by trained interviewers using structured questionnaires. The SPSS version 26 software was used to analyse the data. Propensity score matching analysis was performed to control for possible confounding biases. The average effects of the intervention were estimated using multivariate general linear modelling to estimate for mean differences and odds ratio based on the nature of data. RESULTS: The result showed that the ITNs utilization was 6.857 folds in the intervention groups compared to the counterpart; (OR = 6.857; 95% CI: (4.636, 10.1430); effect size = 39%). A mean differences (MD) of self-efficacy (MD = 15.34; 95% CI: 13.73 to 16.95), knowledge (MD = 5.83; 95% CI: 5.12 to 6.55), attitude (MD = 6.01; 95% CI: 5.26 to 6.77), perceived malaria risk (MD = 2.14; 95% CI: 1.53 to 2.76), and perceived family supports (MD = 6.39; 95% CI: 5.57 to 7.22) were observed favoring the intervention. Multivariable logistic regression modelling results showed that knowledge (ß = 0.194, 95% CI: 1.09 to 1.35) and perceived family supports (ß = 0.165, 95% CI: 1.11 to 1.25) and self-efficacy (ß = 0.10, 95% CI: 1.22 to 2.32) predicted the ITN utilization among the school children. CONCLUSIONS: The finding of this study suggested that the school-based SBCC approach combined with peer education activities advanced the malaria-related knowledge, attitude, self-efficacy, risk perceptions, and family supports and ultimately improved the sustained use of ITNs among school-going children. Further research should be conducted to understand the mechanism of these effects given the influences of social, health services, and school systems are considered.

"This Is Not Our Disease": A Qualitative Study of Influencers of COVID-19 Preventive Behaviours in Nguenyyiel Refugee Camp (Gambella, Ethiopia).

The COVID-19 pandemic has infected more than 263 million people and claimed the lives of over 5 million people worldwide. Refugees living in camp settings are particularly vulnerable to infection because of the difficulty implementing preventive measures and lack of medical resources. However, very little is known about the factors that influence the behavioural response of refugees towards COVID-19. There is an urgent need for field evidence to inform the design and implementation of a robust social and behaviour change communication strategy to respond to the threat posed by COVID-19 in humanitarian settings. This study examines factors influencing COVID-19-related behavioural decisions in the Nguenyyiel refugee camp located in Gambella, Ethiopia using data collected from focus group discussions and key informant interviews in September 2020. The evidence suggests that while a number of factors have been facilitating the adoption of COVID-19 prevention measures, including good general knowledge about the virus and the necessary preventive strategies and the active engagement by community leaders and non-governmental organisations, important structural and cultural factors have hindered the uptake of COVID-19 prevention measures. These include: difficultly staying at home to minimise physical contact; overcrowding in the camp and within home dwellings; a lack of hand sanitizers and masks and of funds to purchase these; inconsistent use of facemasks when available; COVID-19 denial and misconceptions about the disease, and other cultural beliefs and habits. Overall, the study found that refugees perceived COVID-19 to pose a low threat (susceptibility and severity) and had mixed beliefs about the efficacy of preventive behaviours. This study identified gaps in the existing information education and communication strategy, including a lack of consistency, inadequate messaging, and a limited use of communication channels. While awareness of COVID-19 is a necessary first step, it is not sufficient to increase adoption of prevention measures in this setting. The current communication strategy should move beyond awareness raising and emphasise the threat posed by COVID-19 especially among the most vulnerable members of the camp population. This should be accompanied by increased community support and attention to other barriers and incentives to preventive behaviours.

Growth rate of clinically diagnosed superficial basal cell carcinoma and changes in dermoscopic features over time.

BACKGROUND/OBJECTIVES: Basal cell carcinoma (BCC) is the most commonly occurring skin cancer. BCCs have been found to generally grow slowly. Data are limited on how the dermoscopic characteristics of BCCs evolve. We set out to determine the growth rate of superficial BCCs (sBCC) and assess the change in dermoscopic features over time. METHODS: A retrospective review was performed of clinically diagnosed sBCC. Images, demographic and dermoscopic data were collected by a melanographer. Mixed effects linear regression models were used to investigate sBCC growth and associations between size and dermoscopic/demographic variables. We tested differences in trends over time in dermoscopic features using non-parametric trend tests. RESULTS: 100 individual sBCC were evaluated in 70 patients (mean age 62; 59% male), 69% had Fitzpatrick skin phototype 1 or 2, and 81% had some degree of actinic damage. sBCC were present on the back in 58% and 22% of men and women, respectively. The median surface area was 41.9 mm2 with a growth rate of 0.81 mm2 /month. Males had larger sBCC than females. There was no association between sBCC size and Fitzpatrick skin phototype, history of skin cancer or family history of melanoma. There is some evidence larger sBCC gain shiny white structures (P = 0.053) over time. CONCLUSIONS: sBCC grow at a rate unlikely to adversely affect patient outcomes associated with long wait times. Our data suggest that dermoscopy can aid in appropriate treatment selection for sBCC.

Facebook Powered Measurement and Evaluation for Iron Folic Acid Health Intervention in India.

As the media landscape changes and billions of people around the world turn to Facebook, Instagram, WhatsApp, and other social media platforms for information and social interactions, the need to develop effective methods of leveraging social media for social behavior change communication (SBCC) becomes increasingly important. Yet, in order for the public health sector to embrace social media for SBCC, we must have methods for measuring the impact of social media-based SBCC. In this letter, we share a new approach for measurement and evaluation of social media-based SBCC campaigns. The approach was developed as part of an iron-folic acid health intervention targeting young women in two states in northern India; Uttar Pradesh and Maydar Pradesh.

Mechanism of DNA End Sensing and Processing by the Mre11-Rad50 Complex.

DNA double-strand breaks (DSBs) threaten genome stability throughout life and are linked to tumorigenesis in humans. To initiate DSB repair by end joining or homologous recombination, the Mre11-nuclease Rad50-ATPase complex detects and processes diverse and obstructed DNA ends, but a structural mechanism is still lacking. Here we report cryo-EM structures of the E. coli Mre11-Rad50 homolog SbcCD in resting and DNA-bound cutting states. In the resting state, Mre11's nuclease is blocked by ATP-Rad50, and the Rad50 coiled coils appear flexible. Upon DNA binding, the two coiled coils zip up into a rod and, together with the Rad50 nucleotide-binding domains, form a clamp around dsDNA. Mre11 moves to the side of Rad50, binds the DNA end, and assembles a DNA cutting channel for the nuclease reactions. The structures reveal how Mre11-Rad50 can detect and process diverse DNA ends and uncover a clamping and gating function for the coiled coils.

Use of short message service for monitoring Zika-related behaviors in four Latin American countries: lessons learned from the field.

BACKGROUND: Effective response to widespread epidemics relies in part on rapidly changing information from affected communities as individuals react to emergency response efforts. The short message service (SMS) approach was used to monitor knowledge, prevention, and behavior during an outbreak of Zika cases in Honduras, El Salvador, the Dominican Republic, and Guatemala in 2017. SMS methods supported collection of monitoring data at a time of heightened reliance on communication via mobile phones, and when the use of phones for epidemic-related communication was amplified. SMS methods were used to collect monitoring data on knowledge of Zika risk and prevention, and behaviors to prevent Zika infection. METHODS: Serial SMS surveys were conducted over a seven-month period to capture changing community perceptions of risk and behaviors to prevent Zika during the epidemic. This article discusses the development of the SMS surveys, from planning and designing tools to collecting the data, and the unique experiences encountered during survey implementation. RESULTS: Special considerations for the effective use of SMS for data collection are described, including market penetration of mobile phones, predominant phone types in use, preparation of communities and the target audience, options for tailoring questionnaires to the available technology, relationships with telecommunication companies, and supporting participants' ability to complete questionnaires. The article discusses issues related to the development of the questionnaires, context-specific challenges before and during implementation of the surveys, and creative strategies to overcome barriers. Lessons learned, and recommendations to increase opportunities for a successful SMS survey, are included. CONCLUSIONS: Understanding the social and economic context of mobile phone use in the target area and careful crafting of SMS questionnaires can produce useful data that may rival information captured through other approaches, such as Knowledge, Attitudes and Practices (KAP) surveys. Despite the challenges experienced, there is room for more consistent and widespread use of SMS for data collection in Latin America.

How does a Social and Behavioral Change Communication Intervention Predict Menstrual Health and Hygiene Management: A Cross-Sectional Study.

BACKGROUND: Interventions in India to improve menstrual health and hygiene management (MHHM) have been implemented at the national, state, district and school level. However, evaluations of these interventions have been scarce. The objective of the study was to determine if a social and behavioral change communication (SBCC) intervention (GARIMA) had a relationship with knowledge, attitudes, interpersonal communication, restrictions and MHHM using a comparison group post-test only design among 2206 adolescent girls. METHODS: Intervention villages and adolescent girls were selected through stratified random sampling based on where GARIMA was implemented. Villages and adolescent girls in comparison villages were matched socio-demographically to intervention villages and adolescent girls. Multi-level logistic regressions assessed the relationship between the encoded exposure, mediators and MHHM. RESULTS: The results showed that the encoded exposure predicted all behaviors corresponding to MHHM. Additionally, adolescent girls in the high encoded exposure group had significantly higher knowledge about puberty and reproductive parts (AOR: 2.03 (95% CI: 1.31 - 3.15)), positive attitudes towards gender (AOR: 1.48 (95% CI: 1.02 - 2.16)) and higher levels of some discussion and dialogue (AOR: 1.41 (95% CI: 1.04 - 1.92)). CONCLUSIONS: Future programs should use SBCC to improve MHHM behavior but involve families, peers and community members to a greater extent in order to improve attitudes towards menstruation, attitudes towards restrictions, attitudes towards absorbent use and reduce restrictions within the community.

The SbcC and SbcD homologs of the cyanobacterium Anabaena sp. strain PCC7120 (Alr3988 and All4463) contribute independently to DNA repair.

The ubiquitous SbcCD exonuclease complex has been shown to perform an important role in DNA repair across prokaryotes and eukaryotes. However, they have remained uncharacterized in the ancient and stress-tolerant cyanobacteria. In the cyanobacterium Anabaena sp. strain PCC7120, SbcC and SbcD homologs, defined on the basis of the presence of corresponding functional domains, are annotated as hypothetical proteins, namely Alr3988 and All4463 respectively. Unlike the presence of sbcC and sbcD genes in a bicistronic operon in most organisms, these genes were distantly placed on the chromosome in Anabaena, and found to be negatively regulated by LexA. Both the genes were found to be essential in Anabaena as the individual deletion mutants were non-viable. On the other hand, the proteins could be individually overexpressed in Anabaena with no effect on normal cell physiology. However, they contributed positively to enhance the tolerance to different DNA damage-inducing stresses, such as mitomycin C and UV- and γ-radiation. This indicated that the two proteins, at least when overexpressed, could function independently and mitigate the damage caused due to the formation of DNA adducts and single- and double-strand breaks in Anabaena. This is the first report on possible independent in vivo functioning of SbcC and SbcD homologs in any bacteria, and the first effort to functionally characterize the proteins in any cyanobacteria.

Framework for evaluating external and internal parameters associated with Sea Based Container Culture (SBCC): Towards understanding rearing success in European lobsters (Homarus gammarus).

Sea Based Container Culture (SBCC) is a mariculture technique that relies on the natural maintenance of environmental conditions, such as Dissolved Oxygen (DO) concentration and feed availability. This paper discusses a framework to evaluate the rearing success of European Lobsters (Homarus gammarus) in SBCC based on temporal and spatial variations of external parameters, including current velocity, wave velocity, turbulent fluctuations and dissolved oxygen concentrations. The temporal variations considered annual changes to the environment and the effect of biofouling growth, and the spatial variations considered the geographical location (case study of Falmouth bay, Cornwall) and vertical position in the water column. The internal parameters of the containers were modelled using transfer functions derived from previous experimental data. The internal parameters were compared to rearing limitations selected from available literature, which included foraging and mobility behaviours, and DO consumption. The time that internal parameters exceeded the rearing limitations was quantified, allowing rearing success to be predicted. This paper uses a case study of external parameters measured in Cornish waters, UK, to demonstrate the framework methodology. The framework showed that in situ measurements of current, wave and turbulence could be used to predict the internal parameters of SBCC containers, which can be used to predict theoretical rearing success based on rearing limitations. The framework indicated that DO concentrations within the containers should not affect rearing success; however, the foraging and mobility limits were exceeded by 0 to 30% of the time (depending on vertical position in the water column and assessment method). The paper aims to demonstrate the generic framework methodology and understands its limitations in predicting rearing success. The framework provides a tool to optimise the SBCC design for spatial and temporal varying conditions related to a geographical location or (vice versa) identify suitable mariculture sites based on SBCC design and environmental conditions. Additionally, the framework can optimise the vertical position of the SBCC in the water column and identify, from parameters considered, those that are most likely to affect rearing success.

Accuracy of dermoscopic criteria for discriminating superficial from other subtypes of basal cell carcinoma.

BACKGROUND: The management of basal cell carcinoma (BCC) depends, among other factors, on its histopathologic subtype. Although dermoscopic criteria of BCC have been investigated, the possible role of dermoscopy in predicting the tumor subtype remains unclear. OBJECTIVES: We sought to assess the diagnostic accuracy of dermoscopic criteria for differentiating superficial BCC (sBCC) from other BCC subtypes. METHODS: Dermoscopic images of histopathologically confirmed BCCs were retrospectively evaluated for the presence of predefined criteria. Univariate and adjusted odds ratios were calculated. Discriminant functions were used to plot receiver operating characteristic curves. RESULTS: In all, 77 sBCCs and 258 non-sBCCs were included. Maple leaf-like areas, short fine superficial telangiectasia, multiple small erosions, and shiny white-red structureless areas were potent predictors of sBCC, each making its diagnosis over 5-fold more likely. Conversely, the presence of arborizing vessels, blue-gray ovoid nests, and ulceration gave 11-fold, 15-fold, and 3-fold increased possibility for the diagnosis of non-sBCCs, respectively. Based on the results of the multivariate analysis, we propose a diagnostic algorithm that can predict the diagnosis of sBCC with a sensitivity of 81.9% and a specificity of 81.8%. LIMITATIONS: The retrospective design and the inclusion of only Caucasian patients are limitations. CONCLUSION: Dermoscopy is reliable in differentiating sBCC from other BCC subtypes.
