Evaluation of knowledge, attitude, practices and effectiveness of menstrual hygiene interventions in rural schools from Lilongwe, Malawi.

BACKGROUND: Menstrual hygiene management (MHM) is associated with the menstrual process in women and adolescent girls who face cultural and financial challenges in rural areas of many developing countries. As part of the pilot study, we assessed the sustainability and effectiveness of the approaches and lessons learned from the MHM project intervention in rural areas of Lilongwe, Malawi. METHODS: Rural primary schools (n = 4) were purposively selected where an MHM intervention was implemented in Lilongwe, Malawi. The study employed a mixed-method research design. Assessments and data collection were performed through surveys of learners, literature reviews, key informant interviews (KIIs) (n = 90), and 20 focus group discussions (FGDs). The study participants included boys and adolescent girls (n = 100, 11-19 years; grades 5-8), teachers, mother groups, and community leaders from the selected schools. RESULTS: All the schools had water sanitation and hygiene facilities and latrines (45% improved, 54% ventilated improved pit latrines - VIPs) that promoted menstrual hygiene for adolescent girls. However, two of the schools studied (50%, n = 4) did not have separate washrooms for changing sanitary materials. There was a slight increase in latrine coverage in Kabuthu zone communities (90% at baseline versus 93.4% at midterm). However, the coverage dropped to 85.7% at the final evaluation, which was attributed to too much rain received in the area that damaged most of the latrines. There was a significant reduction (p < 0.05) in the number of girls failing to attend classes due to menstruation (70% at baseline versus 14% at final evaluation). Furthermore, the project resulted in the majority of girls (94.4%) having access to school. There was a strong uptake and adoption of sanitary products (reusable pads and menstrual cups) among adolescent girls of all age groups. The study has demonstrated that the inclusion of key stakeholders such as health workers, parents, mother groups and community leaders promoted the uptake and sustainability of reusable pads and menstrual cups and MHM interventions and programs. CONCLUSION: The MHM project implementation improved adolescent girls' education in the area. The inclusion of boys and other key stakeholders in the health education talks addressed issues of stigma and discrimination. The study, therefore, calls for comprehensive training on MHM and hygiene education to remove discrimination and harmful cultural practices.

A brief instrument measuring the water, sanitation and hygiene domain of menstrual health among women who inject drugs.

BACKGROUND: Domains of adequate menstrual health (MH) include access to water, sanitation, and hygiene (WASH). People who menstruate with social disadvantages-such as homelessness or drug injection practices-often face barriers to WASH access. However, validated instruments to measure MH are limited among marginalized populations, and available instruments involve lengthy surveys. We developed and evaluated psychometric properties of a novel 'MH WASH Domain Scale-12' among people who menstruate and who inject drugs in the Tijuana-San Diego region and identified correlates of MH access using this scale. METHODS: We constructed a MH-scale based on access to twelve WASH-related items: (1) menstrual products, (2) body hygiene (bathing per week), (3) water sources for bathing, (4) improved, (5) non-shared, (6) available, (7) private, (8) nearby, (9) and safe sanitation facilities, (10) availability of soap, (11) water source for handwashing, and (12) handwashing facilities with soap/water. Variables were dichotomized and summed, with scores ranging from 0-12 points and higher scores indicating better MH access. We assessed the scale's reliability and construct and content validity using data from a binational cross-sectional study. The sample included people who inject drugs (PWID) who had ever menstruated in their lifetime and were 18+ during 2020-2021. MH-WASH items were described, and the scale was further used as an outcome variable to identify correlates. RESULTS: Among 125 (124 cis-female and 1 trans-male) PWID that reported menstruating, our 'MH WASH Domain Scale-12' was reliable (Cronbach's alpha = 0.81, McDonald's Omega total = 0.83) and valid. We identified two sub-domains: Factor-1 included items describing 'WASH availability' and Factor-2 contained items related to 'WASH security'-encompassing physical and biological safety. Scale scores were significantly lower among participants experiencing unsheltered homelessness compared to participants experiencing sheltered homelessness or living in permanent housing. CONCLUSION: We constructed and validated a novel and reliable scale to measure MH-related WASH access that can be used to assess MH among marginalized populations in English- and Spanish-speaking contexts. Using this scale we identified disparities in MH-WASH access among PWID and who menstruate in the US-Mexico border region.

Transgender persons and structural intersectionality: Towards menstrual justice for all menstruators in India.

Government policies concerning access to menstrual hygiene primarily focus on adolescent girls and women, leaving out transgender individuals. Addressing access to menstrual hygiene for transgender persons will require two key steps: first, their inclusion in current policies, and second, framing additional policies to address specific needs. Due to the absence of specific studies on this subject, this commentary relies on personal narratives and international studies. Improving access to menstrual hygiene among transgender individuals will require the enhancing of the availability of menstrual hygiene products, mitigating of stigma and fear of harassment, sensitising of healthcare workers, and ensuring the availability of proper washrooms. In addition, addressing the menstrual injustice experienced by transgender persons involves addressing socioeconomic factors such as caste, poverty, and access to education. Using the lens of structural intersectionality, this article undertakes a review of oppressive systems causing menstrual injustice. This approach is intended to enable policymakers and researchers to consider the multifaceted identities of menstruators, fostering a holistic understanding that will inform their approach towards achieving menstrual equality.

A study to evaluate WASH interventions and risk factors of diarrhoea among children under five years, Anloga district, Ghana: A research protocol.

INTRODUCTION: Good Water, Sanitation and Hygiene (WASH) practices, introduction of Rotavirus vaccination, zinc supplementation and improved nutrition have contributed significantly to the reduction of diarrhoea morbidity and mortality globally by 50%. In spite of these gains, diarrhoea still remains a leading cause of morbidity and mortality in children under-five. Causes of diarrhoea are multifaceted with many factors such as seasonality, behaviour, pathogenicity, epidemiology, etc. However, assessments on the causes of diarrhoea have generally been tackled in silos over the years focusing only on particular causes. In this study, we describe an integrated approach (evaluating WASH interventions implantation processes, assessing epidemiolocal risk factors, and identifying pathogens causing diarrhoea) for assessing determinants of diarrhoea. METHODS: The study has ethical approval from the Ghana Health Service Ethical Review Committee (GHSERC:020/07/22). It will employ three approaches; a process evaluation and a case-control study and laboratory analysis of diarrhoea samples. The process evaluation will assess the detailed procedures taken by the Anloga district to implement WASH interventions. A desk review and qualitative interviews with WASH stakeholders purposively sampled will be done. The evaluation will provide insight into bottlenecks in the implementation processes. Transcribed interviews will be analysed thematically and data triangulated with reviews. A 1:1 unmatched case-control study with 206 cases and 206 controls to determine risk factors associated with diarrhoea in children under-five will also be done. Odds ratios at 5.0% significance level would be calculated. Stool samples of cases will be taken and tested for diarrhoea pathogens using Standard ELISA and TAQMAN Array Card laboratory procedures. EXPECTED OUTCOME: It is expected that this framework proposed would become one of the robust approaches for assessing public health community interventions for diseases. Through the process evaluation, epidemiological case-control study and pathogen identification, we would be able to identify the gaps in the current diarrhoea assessments, come up with tailored recommendations considering the existing risk and assumptions and involve the relevant stakeholders in reducing the diarrhoea burden in a coastal setting in Ghana.

Water, sanitation, and hygiene access among people who inject drugs in Tijuana and San Diego in 2020-2021: a cross-sectional study.

BACKGROUND: Water, sanitation, and hygiene (WASH) access is critical to public health and human dignity. People who inject drugs (PWID) experience stigma and structural violence that may limit WASH access. Few studies have assessed WASH access, insecurity, and inequities among PWID. We describe WASH access, social and geographic inequalities, and factors associated with WASH insecurity among PWID in the Tijuana-San Diego metropolitan area. METHODS: In this cross-sectional binational study, we interviewed PWID (age 18+) in 2020-2021 about WASH access and insecurity. City of residence (Tijuana/San Diego) and housing status were considered as independent variables to describe key WASH access outcomes and to assess as factors associated with WASH insecurity outcomes. Measures of association between outcomes and independent variables were assessed using log modified-Poisson regression models adjusting for covariates. RESULTS: Of 586 PWID (202 Tijuana; 384 San Diego), 89% reported basic access to drinking water, 38% had basic hand hygiene, 28% basic sanitation, and 46% access to bathing, and 38% reported recent open defecation. Participants residing in Tijuana reported significantly higher insecurity in accessing basic drinking water (aRR: 1.68, 95%CI: 1.02-2.76), basic hygiene (aRR: 1.45, 95%CI: 1.28-1.64), and bathing (aRR: 1.21, 95%CI: 1.06-1.39) than those living in San Diego. Participants experiencing unsheltered homelessness experienced significantly higher insecurity in accessing basic drinking water (aRR: 2.03, 95%CI: 1.07-3.86), basic sanitation (aRR: 1.68, 95%CI: 1.48, 1.92), bathing (aRR: 1.84, 95%CI: 1.52-2.22), and improved water sources for cleaning wounds (aRR: 3.12, 95%CI: 1.55-6.29) and for preparing drugs (aRR: 2.58, 95%CI: 1.36-4.89) than participants living in permanent housing. CONCLUSION: WASH access among PWID in the Tijuana-San Diego metropolitan area was low by international standards and lower than the national averages in both countries. Homelessness was significantly associated with WASH insecurity in this population. Concentrated efforts are needed to guarantee continuously available WASH services for PWID-especially those who are unsheltered.

Comparison of two approaches to measuring clean faces as part of the facial cleanliness component of the SAFE trachoma elimination strategy.

BACKGROUND: The Alliance for the Global Elimination of Trachoma (GET) endorses the full SAFE strategy to eliminate trachoma; Surgery (for trichiasis), Antibiotics (to reduce the community pool of infection, Facial cleanliness, and Environmental improvement (to decrease transmission). There is no accepted measure of facial cleanliness. This study compared two possible metrics for facial cleanliness. METHOD/FINDINGS: Metric one: Clean face was defined as observed absence of ocular and nasal discharge on the face. Metric two: observing a grade of dirtiness (scale 10 = lightest to 0 = darkest) on a standard facial wipe. The reliability of grading a child's face or grading a facial wipe was determined in children in Kongwa Tanzania. We also observed both measurements in a cohort of 202 children ages 1 to <7years prior to face cleaning, immediately afterwards, and 4 hours afterwards. Fifty of the children did not have face cleaning and were controls. Intra-and interobserver reliability was similar for both measures, the latter = 0.53 for observing a clean face and 0.52 for grading a facial wipe. There was no correlation between the two. Both measures detected facial cleaning, compared to control children who were not cleaned, immediately after cleaning; control children with 53% clean faces and wipe score of 6.7 compared to cleaned children with 88% clean faces and wipe score of 8 (p = .0001, p = < .0001, respectively). Both measures also detected face washing 4 hours previously compared to controls. CONCLUSIONS: The two metrics were equally reliable, and both measured the behavior of face washing. They measure different aspects of a clean face; one measures the amount of dirt on wiped area and the other measures ocular and nasal discharge. Both measurements appear to capture the behavior of facial cleaning, and the choice of metric would appear to rest on the measurement that captures the stated objective of the behavior, consideration of costs, training, logistics, and implementation.

The state of reporting context and implementation in peer-reviewed evaluations of water, sanitation, and hygiene interventions: A scoping review.

INTRODUCTION: To accurately assess evidence from environmental and public health field trials, context and implementation details of the intervention must be weighed with trial results; yet these details are under and inconsistently reported for water, sanitation, and hygiene (WASH), limiting the external validity of the evidence. METHODS: To quantify the level of reporting of context and implementation in WASH evaluations, we conducted a scoping review of the 40 most cited evaluations of WASH interventions published in the last 10 years (2012-2022). We applied criteria derived from a review of existing reporting guidance from other sectors including healthcare and implementation science. We subsequently reviewed main articles, supplements, protocols, and other associated resources to assess thoroughness of context and implementation reporting. RESULTS: Of the final 25 reporting items we searched for, four-intervention name, approach, location, and temporality-were reported by all studies. Five items-theory, implementer qualifications, dose intensity, targeting, and measured fidelity-were not reported in over a third of reviewed articles. Only two studies (5%) reported all items in our checklist. Only 74% of items were found in the main article, while the rest were found in separate papers (7%) or not at all (19%). DISCUSSION: Inconsistent reporting of WASH implementation illustrates a major challenge in the sector. It is difficult to know what interventions are actually being evaluated and how to compare evaluation results. This inconsistent and incomplete implementation reporting limits the ability of programmers and policy makers to apply the available evidence to their contexts. Standardized reporting guidelines would improve the application of the evidence for WASH field evaluations.

Physical activity levels in various university majors amidst the COVID-19 pandemic: a comparative study / Nivel de actividad física en varias carreras universitarias en medio de la pandemia de COVID-19: Un estudio comparativo / Níveis de atividade física em várias carreiras universitárias em meio à pandemia de COVID-19: Um estudo comparativo

This study determined levels of physical activity in students by comparing them based on gender, faculty, and major among university students during the Covid-19 pandemic. The research followed a quantitative approach with a descriptive-comparative design. The study was conducted once per student, with the participation of 582 students of both genders. The International Physical Activity Questionnaire (IPAQ) was administered to the students using Google Forms, distributed through their institutional emails. The collected data were analyzed using the statistical software SPSS V.22.0. The independent samples t-test was employed to compare the energy expenditure between males and females, along with Cohen's d statistic to assess the effect size. Prior to these analyses, the Kolmogorov-Smirnov normality test and Levene's test were conducted. Results were considered significant when the p-value was <0.05. The findings indicate that males allocate more time to work than females. Additionally, it was observed that males exhibit a higher level of physical activity than females within the engineering field. Lastly, majors with the highest levels of physical activity per week were Physical Education and Nutrition. These outcomes shed light on the reality of physical activity levels among Chilean university students based on faculty and major. University authorities should consider promoting physical activity programs, particularly emphasizing women and majors such as engineering, architecture, and mathematics, which have shown lower levels of physical activity.

Adicionalmente, observou-se que os homens apresentam um nível mais elevado de atividade física do que as mulheres no campo da engenharia. Por fim, os cursos com os níveis mais altos de atividade física por semana foram Educação Física e Nutrição. Estes resultados lançam luz sobre a realidade dos níveis de atividade física entre estudantes universitários chilenos com base na faculdade e no curso. As autoridades universitárias devem considerar a promoção de programas de atividade física, especialmente enfatizando as mulheres e os cursos como engenharia, arquitetura e matemática, que mostraram níveis mais baixos de atividade física.

Determinants of malaria infections among children in refugee settlements in Uganda during 2018-2019.

BACKGROUND: While 5% of 247 million global malaria cases are reported in Uganda, it is also a top refugee hosting country in Africa, with over 1.36 million refugees. Despite malaria being an emerging challenge for humanitarian response in refugee settlements, little is known about its risk factors. This study aimed to investigate the risk factors for malaria infections among children under 5 years of age in refugee settlements in Uganda. METHODS: We utilized data from Uganda's Malaria Indicator Survey which was conducted between December 2018 and February 2019 at the peak of malaria season. In this national survey, household level information was obtained using standardized questionnaires and a total of 7787 children under 5 years of age were tested for malaria using mainly the rapid diagnostic test. We focused on 675 malaria tested children under five in refugee settlements located in Yumbe, Arua, Adjumani, Moyo, Lamwo, Kiryadongo, Kyegegwa, Kamwenge and Isingiro districts. The extracted variables included prevalence of malaria, demographic, social-economic and environmental information. Multivariable logistic regression was used to identify and define the malaria associated risk factors. RESULTS: Overall, malaria prevalence in all refugee settlements across the nine hosting districts was 36.6%. Malaria infections were higher in refugee settlements located in Isingiro (98.7%), Kyegegwa (58.6%) and Arua (57.4%) districts. Several risk factors were significantly associated with acquisition of malaria including fetching water from open water sources [adjusted odds ratio (aOR) = 1.22, 95% CI: 0.08-0.59, P = 0.002], boreholes (aOR = 2.11, 95% CI: 0.91-4.89, P = 0.018) and water tanks (aOR = 4.47, 95% CI: 1.67-11.9, P = 0.002). Other factors included pit-latrines (aOR = 1.48, 95% CI: 1.03-2.13, P = 0.033), open defecation (aOR = 3.29, 95% CI: 1.54-7.05, P = 0.002), lack of insecticide treated bed nets (aOR = 1.15, 95% CI: 0.43-3.13, P = 0.003) and knowledge on the causes of malaria (aOR = 1.09, 95% CI: 0.79-1.51, P = 0.005). CONCLUSIONS: The persistence of the malaria infections were mainly due to open water sources, poor hygiene, and lack of preventive measures that enhanced mosquito survival and infection. Malaria elimination in refugee settlements requires an integrated control approach that combines environmental management with other complementary measures like insecticide treated bed nets, indoor residual spraying and awareness.

Safe Drinking Water, Sanitation and Mother's Hygiene Practice as Stunting Risk Factors: A Case Control Study in a Rural Area of Ciawi Sub-district, Tasikmalaya District, West Java, Indonesia.

Background: Stunting is associated with disorders of the small intestines caused by environmental factors and poor hygiene practices. Prevention of stunting should be conducted in the first 1,000 days of life; namely, from conception until the child is two years old. This research aimed to analyze the relationship between environmental risk factors and maternal personal hygiene with the incidence of stunting in children aged 6-23 months. Methods: This study was conducted using a case-control design, with a total sample of 212 (106 cases and 106 controls) enrolled purposively. Data were collected through interviews using a questionnaire. The analysis used chisquare tests and multiple logistic regression. Results: The results of multivariate analysis showed the independent variables that have a significant association on the incidence of stunting are access to safe drinking water and maternal hygiene practices. The external variables that have a significant relationship is birth length and feeding practice. Conclusion: Having no access to safe drinking water, not proper sanitation, and poor maternal hygiene practices have a higher risk of stunting in children aged 6-23 months. The implications of this research include the need for increased access to a safe environment and improvement of mother's behavior as essential efforts to prevent stunting.

Determinants of bather hygiene in public swimming pools: a mixed-methods analysis of online discussion comments.

Swimming in public pools can expose bathers to microbiological (e.g., Cryptosporidium) and chemical (e.g., disinfection by-product) hazards, which can lead to recreational water illness. Adequate hygienic behaviours among bathers are important to reduce these risks. However, prior studies have found low compliance with pre-swim showering and avoidance of urinating in pools. We conducted a mixed-methods analysis of online discussion comments to identify key determinants of these two behaviours. We identified relevant discussion threads on Reddit, Quora, and swimming forums. Identified comments were classified as having a positive or negative sentiment towards the behaviour, and they were thematically analyzed according to the Theoretical Domains Framework (TDF). We analyzed 986 comments from 45 threads; 49.8% of comments were classified as expressing a positive sentiment towards the behaviour. Positive sentiments were more commonly expressed towards pre-swim showering compared to avoidance of urinating in pools (60.1 vs. 47.1%). Eleven themes were identified across the following eight TDF domains: beliefs about consequences (n = 362 comments), social influences (n = 298), beliefs about capabilities (n = 240), social/professional role and identity (n = 144), knowledge (n = 138), emotions (n = 137), reinforcement (n = 78), and environmental context and resources (n = 33). Results can help to inform targeted educational and outreach strategies with bathers to encourage increased adoption of hygienic behaviours.

Assessment of hygiene practices and microbial safety of milk supplied by smallholder farmers to processors in selected counties in Kenya.

Smallholder farmers dominate the Kenyan dairy sector producing 95% of the total milk. However, several concerns have been raised on the quality and safety of the milk they produce. This study assessed the hygienic practices and microbial safety of milk supplied by smallholder farmers to processors in Bomet, Nyeri, and Nakuru counties in Kenya. Interviews and direct observations were carried out to assess hygiene and handling practices by farmers and a total of 92 milk samples were collected along four collection channels: direct suppliers, traders, cooperatives with coolers, and cooperatives without coolers. Microbial analysis was done following standard procedures and data analysed using GenStat and SPSS. This study revealed that farmers did not employ good hygienic practices in their routine dairy management. They used plastic containers for milking and milk storage (34.2%); they did not clean sheds (47.9%) and did not set aside cows that suffered from mastitis factors (83.6%), resulting in poor microbial quality of raw milk along the collection channels. The highest mean total viable counts (8.72 log10 cfu/ml) were recorded in Nakuru while Nyeri had the highest mean E. coli counts (4.97 log10 cfu/ml) and Bomet recorded the highest mean counts of 5.13 and 5.78 log10 cfu/ml for Staphylococcus aureus and Listeria monocytogenes respectively. Based on all above-mentioned parameters, the microbial load in most samples from all three counties exceeded the set Kenyan standards. Farmer training, improving road infrastructure, use of instant coolers at cooperatives, and quality-based payment systems are recommended as measures to curb microbial growth.

Prevalence of Tungiasis and its risk factors of among children of Mettu woreda, southwest Ethiopia, 2020.

Tungiasis is caused by the flea tunga penetrans and results in painful skin lesions, skin infections, and permanent disability. However, limited information is available that shows the magnitude of the problem and its risk factors that help for intervention in Ethiopia. The goal of this study was to determine the prevalence and risk factors of tungiasis in children aged 5 to 14 in Mettu woreda in 2020. A community based cross sectional study was conducted among randomly selected kebeles of Mettu woreda, in Southwest Ethiopia. To select study participants, multistage sampling was used. The data were collected through physical examination of the children, interview of parents/guardians of the children, and observation of the home environment using checklists and questionnaires. The descriptive analysis was done for socio-demographic characteristics, prevalence of tungiasis, and housing conditions. A logistic regression analysis was performed, and variables in multivariable regression reported odds ratios and their 95% confidence intervals once the variables were identified using a p-value of 0.05 as a risk factor of statistical significance. The prevalence of tungiasis among children 5-14 years of age in Mettu rural woreda was 52 percent (n = 821). As a risk factor, large family size (AOR: 2.9, 95% CI: 2.13, 4.40); school attendance (AOR: 1.5, 95% CI: 1.02, 2.18), floor inside the house (AOR: 3.8, 95% CI: 1.76, 8.43); having sleeping bed (AOR: 0.16, 95% CI: 0.03, 0.82); access to protected water sources (AOR: 0.24, 95% CI: 0.15, 0.39); access to improved toilet facilities(AOR: 0.63: 95% CI: 0.44, 0.89); access to electric services (AOR: 0.30, 95% CI: 0.15, 0.62); and lack of own farmland (AOR: 0.36, 95% CI: 0.26, 0.50) were found. Therefore, planning and implementation of interventions focus on those risk factors that are particularly important. Water, sanitation and hygiene interventions, and livelihood improvement interventions are required to solve the problem in the setting.

Menstrual hygiene practice among adolescent girls in Ethiopia: A systematic review and meta-analysis.

BACKGROUND: Adolescent girls face several challenges relating to menstruation and its proper management. Lack of adequate sanitary products, inadequate water supply, and privacy for changing sanitary pads continue to leave adolescent girls with limited options for safe and proper menstrual hygiene in many low-income settings, including Ethiopia. These situations are also compounded by societal myths, stigmas surrounding menstruation, and discriminatory social norms. This systematic review and meta-analysis aimed to estimate the pooled proportion of safe menstrual hygiene management among adolescent girls in Ethiopia using the available studies. METHODS: We searched PubMed, Google Scholar, African Journal Online (AJOL), Hinari, Science Direct, ProQuest, Direct of Open Access Journals, POPLINE, and Cochrane Library database inception to May 31, 2021. Studies reporting the proportion of menstrual hygiene management among adolescent girls in Ethiopia were considered. The Cochrane Q test statistics and I2 tests were used to assess the heterogeneity of the included studies. Since the included studies revealed considerable heterogeneity, a random effect meta-analysis model was used to estimate the pooled proportion of menstrual hygiene management (MHM). RESULTS: Of 1,045 identified articles, 22 studies were eligible for analysis (n = 12,330 participants). The pooled proportion (PP) of safe MHM in Ethiopia was 52.69% (95%CI: 44.16, 61.22). The use of commercial menstrual absorbents was common 64.63% (95%CI: 55.32, 73.93, I2 99.2%) followed by homemade cloth 53.03% (95%CI: 22.29, 83.77, I2 99.2%). Disposal of absorbent material into the latrine was the most common practice in Ethiopia 62.18% (95%CI: 52.87, 71.49, I2 98.7%). One in four girls reported missing one or more school days during menstruation (PP: 32.03%, 95%CI: 22.65%, 41.40%, I2 98.2%). CONCLUSION: This study revealed that only half of the adolescent girls in Ethiopia had safe MHM practices. To ensure that girls in Ethiopia can manage menstruation hygienically and with dignity, strong gender-specific water, sanitation, and hygiene (WASH) facilities along with strong awareness creation activities at every level are needed.

Water, sanitation, and hygiene for control of trachoma in Ethiopia (WUHA): a two-arm, parallel-group, cluster-randomised trial.

BACKGROUND: WHO promotes the SAFE strategy for the elimination of trachoma as a public health programme, which promotes surgery for trichiasis (ie, the S component), antibiotics to clear the ocular strains of chlamydia that cause trachoma (the A component), facial cleanliness to prevent transmission of secretions (the F component), and environmental improvements to provide water for washing and sanitation facilities (the E component). However, little evidence is available from randomised trials to support the efficacy of interventions targeting the F and E components of the strategy. We aimed to determine whether an integrated water, sanitation, and hygiene (WASH) intervention prevents the transmission of trachoma. METHODS: The WASH Upgrades for Health in Amhara (WUHA) was a two-arm, parallel-group, cluster-randomised trial in 40 rural communities in Wag Hemra Zone (Amhara Region, Ethiopia) that had been treated with 7 years of annual mass azithromycin distributions. The randomisation unit was the school catchment area. All households within a 1·5 km radius of a potential water point within the catchment area (as determined by the investigators) were eligible for inclusion. Clusters were randomly assigned (at a 1:1 ratio) to receive a WASH intervention either immediately (intervention) or delayed until the conclusion of the trial (control), in the absence of concurrent antibiotic distributions. Given the nature of the intervention, participants and field workers could not be masked, but laboratory personnel were masked to treatment allocation. The WASH intervention consisted of both hygiene infrastructure improvements (namely, construction of a community water point) and hygiene promotion by government, school, and community leaders, which were implemented at the household, school, and community levels. Hygiene promotion focused on two simple messages: to use soap and water to wash your or your child's face, and to always use a latrine for defecation. The primary outcome was the cluster-level prevalence of ocular chlamydia, measured annually using conjunctival swabs in a random sample of children aged 0-5 years from each cluster at 12, 24, and 36 month timepoints. Analyses were done in an intention-to-treat manner. This trial is ongoing and is registered at ClinicalTrials.gov, NCT02754583. FINDINGS: Between Nov 9, 2015, and March 5, 2019, 40 of 44 clusters assessed for eligibility were enrolled and randomly allocated to the trial groups (20 clusters each, with 7636 people from 1751 households in the intervention group and 9821 people from 2211 households in the control group at baseline). At baseline, ocular chlamydia prevalence among children aged 0-5 years was 11% (95% CI 6 to 16) in the WASH group and 11% (5 to 18) in the control group. At month 36, ocular chlamydia prevalence had increased in both groups, to 32% (24 to 41) in the WASH group and 31% (21 to 41) in the control group (risk difference across three annual monitoring visits, after adjustment for prevalence at baseline: 3·7 percentage points; 95% CI -4·9 to 12·4; p=0·40). No adverse events were reported in either group. INTERPRETATION: An integrated WASH intervention addressing the F and E components of the SAFE strategy did not prevent an increase in prevalence of ocular chlamydia following cessation of antibiotics in an area with hyperendemic trachoma. The impact of WASH in the presence of annual mass azithromycin distributions is currently being studied in a follow-up trial of the 40 study clusters. Continued antibiotic distributions will probably be important in areas with persistent trachoma. FUNDING: National Institutes of Health-National Eye Institute.

Caracterização molecular de Staphylococcus aureus isolados de queijos artesanais da Serra da Canastra / Molecular characterization of Staphylococcus aureus isolated from artisanal cheeses from Serra da Canastra

O queijo Minas Artesanal da Canastra é produzido na Serra da Canastra (MG), utilizando leite cru, coalho e pingo, que é uma cultura endógena natural de cada queijaria. Devido ao uso de leite cru, o produto pode veicular microrganismos causadores de doenças veiculadas por alimentos, como Staphylococcus aureus. A caracterização molecular é uma ferramenta importante para avaliar a população microbiana do alimento e direcionar a aplicação de medidas de controle na produção. Este estudo caracterizou a diversidade genética, o potencial de virulência e determinou o perfil de susceptibilidade a antimicrobianos de S. aureus isolados de queijos produzidos na Serra da Canastra. Para o estudo transversal foram analisados 248 isolados de queijos que tinham um tempo de maturação de 22 dias, provenientes de 83 propriedades. Por outro lado, no estudo longitudinal foram analisados outros 197 isolados coletados ao longo do processo de maturação, provenientes de três propriedades. Os isolados foram submetidos a testes bioquímicos para confirmação do gênero e para a confirmação da espécie de S. aureus, foi identificado o gene nuc por meio da técnica de PCR. Além disso, foi pesquisado o gene mecA para a detecção de S. aureus Resistente a Meticilina (MRSA). Após os testes de confirmação, 144 isolados do estudo transversal e 159 do estudo longitudinal foram positivos para o gene nuc, específico para S. aureus. Posteriormente, o perfil clonal foi determinado por Eletroforese de Campo Pulsado (PFGE) utilizando a enzima SmaI e tipagem do locus agr por PCR multiplex. A análise por PFGE foi realizada no programa BioNumerics. A técnica PCR foi realizada para identificar a presença de genes que codificam a produção de hemolisinas, toxina TSST-1, enterotoxinas SEs (SEA, SEB, SEC, SED, SEE, SEG, SEH, SEI, SEJ, SEO, SEM), formação de biofilme e Componentes Microbianos de Superfície que Reconhecem a Matriz de Moléculas Adesivas (MSCRAMMs). Os isolados foram submetidos ao teste de susceptibilidade a antimicrobianos por disco de difusão. Por último, a formação de biofilme em microplaca de 96 poços, em caldo TSB a 37°C, foi verificada pela metodologia de Cristal Violeta. O gene mecA foi detectado em 1,9% dos 445 isolados. A tipagem agrrevelou que 83 (27,4%) dos isolados são do tipo agr-I, 95 (31,4%) agr-II e 43 (14,2%) agr-III, sendo que não foram detectados isolados classificados como agr-IV. A tipagem por PFGE revelou um total de 54 perfis. Assim, um isolado representativo de cada perfil foi utilizado nos demais testes que mostraram a presença dos genótipos spa mais frequentes t127 e t605 (20,58%); t002 (14,70%), seguidos pelos tipos t267 (8,82%); t1234 e t693 (5,8%) e t021, t177, t306, t321, t359, t442, t521, t693 e t5493 (2,9%). Além disso, encontramos a presença dos genes do grupo SEs, sea 1 (1,8%), seh 11 (20,3%), sei 10 (18,5%), sej 7 (12,9%), seg e seo 14 (25,9%), sem 8 (14,8%), e os genes seb, sec, sed, see e tst não foram detectados. Para os genes das hemolisinas, hla foi positivo em todos os isolados e hlb foi positivo em 53 (98,1%) isolados. Os genes positivos para MSCRAMMS foram fnbA, fnbB 18 (33,3%), clfA, clfB e eno 53 (98,1%), fib 44 (81,4%), bbp 4 (7,4%), cna 17 (31,4%) e ebps 10 (18,5%). Por último, os genes de formação de biofilme icaA e icaD estiveram presentes em 38 (70,3%) e 25 (46,2%) dos isolados, respectivamente. Na avaliação de susceptibilidade a antibióticos dos 54 isolados escolhidos, 25 (46,3%) apresentaram maior resistência a penicilina e 13 (24,0%) a tetraciclina. Em menor porcentagem (1,8%), 1 isolado cada foi resistente a eritromicina, cefoxitina, clindamicina, gentamicina, cotrimazol, azitromicina e trimetropim. Além disso, 8 isolados (14,8%) apresentaram resistência intermediaria a tetraciclina, 3 (5,5%) a gentamicina e 1 (1,8%) a tobramicina. No teste para a determinação da formação de biofilme por cristal violeta, 13,7%, foram classificados em isolados não formadores, 60,8% em fracamente formadores, 25,5% moderadamente formadores e nenhum como fortemente formador. A alta diversidade de cepas de S. aureus observada neste estudo mostrou que existem vários tipos de linhagens circulando na região da Canastra. A caracterização revelou uma elevada frequência de genes de virulência e que mais estudos são necessários para avaliar o potencial de produção de enterotoxinas nos queijos artesanais. A melhora dos procedimentos de higienização durante todas as etapas de produção pode ser uma solução para a redução dos níveis de contaminação por S. aureus

Canastra Minas Artesanal cheese is produced in Serra da Canastra (MG), using raw milk, rennet and a natural endogenous culture called pingo. Due to the use of raw milk, the product can carry microorganisms that cause foodborne diseases, such as Staphylococcus aureus. Molecular characterization is an important tool to assess the microbial population of food and guide the application of control measures in production. This study characterized the genetic diversity, virulence potential and determined the antimicrobial susceptibility profile of S. aureus isolated from cheeses produced in Serra da Canastra. A total of 248 isolates from 22 days ripened cheeses were obtained from 83 properties (cross sectional study). Another 197 isolates were collected during maturation (longitudinal study), in three properties. The isolates were submitted to biochemical tests to confirm the genus and to confirm the S. aureus species, the nuc gene was identified by PCR. In addition, the detection of mecA gene was performed for the detection of Methicillin Resistant S. aureus (MRSA). After confirmation tests, 144 isolates from the cross-sectional study and 159 from the longitudinal study were positive for the nuc gene, specific for S. aureus. Subsequently, the clonal profile of the isolates was determined by Pulsed Field Gel Electrophoresis (PFGE) using the SmaI enzyme and typing of the agr locus by multiplex PCR. PFGE analysis was performed using the BioNumerics program. PCR was performed to identify the presence of genes encoding the production of hemolysins, TSST-1 toxin, enterotoxins SEs (SEA, SEB, SEC, SED, SEE, SEG, SEH, SEI, SEJ, SEO, SEM), biofilm formation and microbial surface components recognizing adhesive matrix molecules (MSCRAMMs). The isolates were submitted to the antimicrobial susceptibility test by disc diffusion. Finally, biofilm formation in a 96-well microplate in TSB broth at 37°C was verified by the Cristal Violeta method. The mecA gene was detected in 1.9% of the 445 isolates. Agr typing revealed that 83 (27.4%) of the isolates are agr-I, 95 (31.4%) agr-II and 43 (14.2%) agr-III, and no isolate was classified as agr-IV. PFGE typing revealed a total of 54 profiles. Thus, a representative isolate of each profile was used in the other tests that showed the presence of the most frequent spagenotypes t127, t605 (20.58%); t002 (14.70%), followed by types t267 (8.82%); t1234, t693 (5.8%) e t021, t177, t306, t321, t359, t442, t521, t693 and t5493 (2.9%). In addition, we found the presence of the genes of the SEs group: sea 1 (1.8%), seh 11 (20.3%), sei 10 (18.5%), sej 7 (12.9%), seg and seo 14 (25.9%), sem 8 (14.8%), while seb, sec, sed, see and tst genes were not detected. For hemolysin genes, hla was positive in all isolates and hlb was positive in 53 (98.1%) isolates. The positive genes for MSCRAMMS were: fnbA, fnbB 18 (33.3%), clfA, clfB e eno 53 (98.1%), fib 44 (81.4%), bbp 4 (7.4%), cna 17 (31.4%) and ebps 10 (18.5%). Finally, the biofilm formation genes icaA and icaD were present in 38 (70.3%) and 25 (46.2%) of the isolates, respectively. In the evaluation of antibiotic susceptibility of the 54 isolates, 25 (46.3%) showed greater resistance to penicillin and 13 (24.0%) to tetracycline. In a lower percentage (1.8%), 1 isolate each was resistant to erythromycin, cefoxitin, clindamycin, gentamicin, contrimazole, azithromycin and trimethoprim. In addition, 8 isolates (14.8%) showed intermediate resistance to tetracycline, 3 (5.5%) to gentamicin and 1 (1.8%) to tobramycin. In the test for the determination of biofilm formation by crystal violet, 13.7% were classified as non-forming isolates, 60.8% as weakly forming, 25.5% moderately forming and none as strongly forming. The high diversity of S. aureus strains observed in this study showed that there are several types of strains circulating in the Canastra region. The characterization revealed a high frequency of virulence genes and that further studies are needed to assess the potential for enterotoxin production in artisanal cheeses. The improvement of hygiene procedures during all stages of production can be a solution for reducing the levels of contamination by S. aureus

An Application of the Integrated Behavioral Model for Water, Sanitation and Hygiene to Assess Perceived Community Acceptability and Feasibility of the Biosand Filter among Maasai Pastoralists in Rural Tanzania.

In addition to diarrheal disease risk, lack of access to safe water may have other indirect effects throughout one's life, such as school and workplace absenteeism, leading to less economic productivity. In contexts with scarce resources and unsafe drinking water, household water treatment and safe storage options such as the Biosand filter (BSF) allows households to directly reduce contamination and increase the quality of their drinking water. This study aimed to develop an understanding of perceived community acceptability and feasibility related to pre- and post-implementation of a BSF pilot project in rural Maasai households in the Ngorongoro Conservation Area (NCA), Tanzania. The study was guided by the Integrated Behavioral Model for Water Sanitation and Hygiene interventions (IBM-WASH) to understand the various factors influencing end-user perceptions of the BSF. In-depth interviews, group discussions and think tanks were conducted among a cross-section of community members, stakeholders, and other actors from May 2016 to September 2017. The data were analyzed using a thematic content analysis approach. A range of perceived contextual, technological, and psychosocial factors were found to potentially affect the acceptability and feasibility of BSF adoption in the NCA, highlighting the complex layers of influences in the setting. Whilst the BSF is seemingly an accepted option to treat water within the NCA, the community identified key barriers that may lower BSF adoption. The application of the IBM-WASH model served as a useful framework for evaluating the introduction of the BSF, identifying insights into contextual, technological, and psychosocial community factors.

Cholera risk in cities in Uganda: understanding cases and contacts centered strategy (3CS) for rapid cholera outbreak control.

INTRODUCTION: in the recent past, cities in sub-Saharan Africa have reported serious cholera outbreaks that last for several months. Uganda is one of the African countries where cities are prone to cholera outbreaks. Studies on cholera in Bangladesh show increased risk of cholera for the immediate household members (contacts) yet the control interventions mainly target cases with little or no focus on contacts. This study aimed to describe the rapid control of cholera outbreaks in Kampala and Mbale cities, Uganda, using, "Cases and Contacts Centered Strategy (3CS)" that consisted of identification and treatment of cases, promotion of safe water, sanitation, hygiene (WaSH) and selective chemoprophylaxis for the contacts. METHODS: a cross-sectional study was conducted in 2015-2016 in the Kampala and Mbale cities during cholera outbreaks. Cholera cases were treated and 816 contacts from 188 households were listed and given cholera preventive packages. Data were collected, cleaned, analysed and stored in spreadsheet. Comparison of categories was done using Chi-Square test. RESULTS: a total of 58 and 41 confirmed cholera cases out of 318 and 153 suspected cases were recorded in Kampala and Mbale cities respectively. The outbreaks lasted for 41 days in both cities. Case fatality rates were high; 12.1% (5/41) for Mbale city and 1.7% (1/58) for Kampala city. Fifty-five percent (210/379) of stool samples were tested by culture to confirm V. choleraeO1. No contacts listed and given cholera preventive package developed cholera. Both sexes and all age groups were affected. In Kampala city, the males were more affected than the females in the age groups less than 14 years, p-value of 0.0097. CONCLUSION: this study showed that by implementing 3CS, it was possible to rapidly control cholera outbreaks in Kampala and Mbale cities and no cholera cases were reported amongst the listed household contacts. The findings on 3CS and specifically, selective antibiotic chemoprophylaxis for cholera prevention, could be used in similar manner to oral cholera vaccines to complement the core cholera control interventions (disease surveillance, treatment of cases and WaSH). However, studies are needed to guide such rollout and to understand the age-sex differences in Kampala city.
