Adequate antenatal care attendance and facility birth rates are increasing in Ethiopia but remain well below national goals and global recommendations. Group ANC (G-ANC), when implemented at higher level facilities, is associated with improved quality and experience of ANC, and increased ANC retention and facility-based delivery. The objectives of the study are to assess the feasibility, acceptability, and impact of G-ANC implemented at lower-level facilities (health posts) on ANC continuation and facility-based delivery. Methods G-ANC will first be piloted in five purposively selected health posts. The study will then use a stepped-wedge design in 36 health posts under six health centers, with randomization of the order of the start of the intervention done at the health center level (clusters). The design will include three time periods: first is a six-month control period with no G-ANC implementation, followed by another six months period where G-ANC will be introduced in half (n=18) of the study health posts, then final six months where G-ANC will be implemented in the remaining 18 health posts. Quantitative and qualitative data collection approaches will be used. The study has “pause and reflect” points designed to iterate on the intervention before rolling out to the next set of sites. Qualitative research will be conducted using in-depth interviews with pregnant women, health care workers, facility managers, and regional health managers. 770 women will be enrolled across all phases. Conclusions The study will inform decision makers locally and globally on whether G-ANC is a feasible service delivery model at the health post level. Effectiveness of G-ANC at increasing ANC retention and facility-based delivery will be reported, as well as its acceptability to pregnant women and Health Extension Workers.

Such labels are usually made with commercial software, which are often inaccessible to under-funded research programs in developing countries. The availability of free fit-for-purpose label design software to under-funded research programs in developing countries would address one of the main roadblocks to modernizing agricultural research. The goal was to develop a new open-source software with design features well-suited for field trials and other agricultural experiments. We report here qrlabelr, a new software for creating print-ready plot labels that builds on the foundation of an existing open-source program. The qrlabelr software offers more flexibility in the label design steps, guarantees true string fidelity after QR encoding, and provides faster label generation to users. The new software is available as an R package and offers customizable functions for generating plot labels. For non-R users or beginners in R programming, the package provides an interactive Shiny app version that can be launched from R locally or accessed online at https://bit.ly/3Sud4xy. The design philosophy of this new program emphasizes the adoption of best practices in plot label design to enhance reproducibility, tracking, and accurate data curation in agricultural research and development studies.","PeriodicalId":504483,"journal":{"name":"Gates Open Research","volume":"86 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140376065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lees","doi":"10.12688/gatesopenres.15399.1","DOIUrl":"https://doi.org/10.12688/gatesopenres.15399.1","url":null,"abstract":"This article addresses the evolving challenges in evaluating insecticide-based tools for vector control. In response to the emergence of insecticide resistance in major malaria vectors, novel chemistries and products are coming to market, and there is a need to review the available testing methodologies. Commonly used methods for evaluating insecticides, such as the World Health Organization (WHO) cone bioassay, are inadequate for the diverse range of tools now available. Innovation to Impact (I2I) has studied the variability in laboratory methods, with the aim of identifying key factors that contribute to variation and providing recommendations to tighten up protocols. The I2I Methods Landscape is a living document which presents a review of existing methods for evaluating vector control tools, with the scope currently extending to insecticide-treated nets (ITNs) and indoor residual sprays (IRS). The review reveals a lack of validation for many commonly used vector control methods, highlighting the need for improved protocols to enhance reliability and robustness of the data that is generated to make decisions in product development, evaluation, and implementation. A critical aspect highlighted by this work is the need for tailored methods to measure endpoints relevant to the diverse modes of action of novel insecticides. I2I envisage that the Methods Landscape will serve as a decision-making tool for researchers and product manufacturers in selecting appropriate methods, and a means to prioritise research and development. We call for collective efforts in the pro-active development, validation, and consistent implementation of suitable methods in vector control to produce the data needed to make robust decisions.","PeriodicalId":504483,"journal":{"name":"Gates Open Research","volume":"213 S699","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140222976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In developing countries like Bangladesh, there has been limited progress in reducing the burden of anaemia in pregnancy. This community-based survey will provide insight into the prevalence and determinants of anaemia during the second and third trimesters of pregnancy. Methods This cross-sectional survey will be conducted in three Upazilas (sub-districts) in rural Bangladesh. A total of 1,500 pregnant women will be recruited in second and third trimester, calculated from last menstrual period. The primary outcome is to determine the prevalence of anaemia (Hb<11 g/dL); haemoglobin will be measured in venous blood by HemoCue. The association between iron deficiency and anaemia will be determined, and the role of drinking water iron level in anaemia aetiology will be explored. Key secondary outcomes include the prevalence of moderate (Hb <10 g/dL) and severe anaemia (Hb <7 g/dL), iron deficiency (ferritin <15 mg/L), and iron deficiency anaemia (concurrent iron deficiency and anaemia). Detailed information on socioeconomic status, current and past pregnancies, knowledge on nutrition and anaemia, water-sanitation-hygiene and maternal mental health status will be collected. Conclusions This study will provide comprehensive information on the prevalence and determinants of anaemia in second and third trimester of pregnancy, and inform anaemia intervention strategies to improve maternal and child health outcomes.

Representative survey data on gender norms are needed to test this assumption. Methods General-population survey participants in Manicaland, Zimbabwe (ages≥15, N=9803) were asked if they agreed/disagreed with statements on gender norms. AGYW at risk of HIV infection were asked whether community views discouraged condom use. Multivariable logistic regression was used to measure variations in community members’ views and associations between AGYW’s perceiving negative gender norms and condom HIV prevention cascades. Results 57% of men and 70% of women disagreed that ‘If I have a teenage daughter and she has sex before marriage, I would be ok with this’; and 41% of men and 57% of women disagreed that ‘If I have a teenage daughter, I would tell her about condoms’. 32% and 69% of sexually-active HIV-negative unmarried AGYW, respectively, said negative community views were important in decisions to use condoms and their friends were not using condoms. In each case, those who agreed had lower motivation to use condoms. Fewer of those with friends not using condoms reported using condoms themselves (39% vs. 68%; p<0.001). 21% of men and 32.5% of women found condom use in marriage acceptable. 74% and 93% of married AGYW at risk, respectively, said negative community views influenced their decisions to use condoms and their friends did not use condoms. Fewer married AGYW reporting friends not using condoms were motivated to use condoms but there was no difference in reported condom use (4.1% vs. 6.9%; p=0.48). Conclusions Negative gender norms can form a barrier to motivation to use condoms in unmarried and married AGYW at risk of HIV infection, and, for unmarried AGYW, to condom use.","PeriodicalId":504483,"journal":{"name":"Gates Open Research","volume":"39 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140077120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Zambia, donor support to the voluntary medical male circumcision (VMMC) program, which previously funded non-governmental organizations as implementing partners, is increasingly being directed through government structures instead. We developed a framework to understand how the behaviors of individual decision-makers within the government could be barriers to this transition. We interviewed key stakeholders from the national, provincial, and district levels of the Ministry of Health, and from donors and partners funding and implementing Zambia’s VMMC program, exploring the decisions required to attain a sustainable VMMC program and the behavioral dynamics involved at personal and institutional levels. Using pattern identification and theme matching to analyze the content of the responses, we derived three core decision-making phases in the transition to a sustainable VMMC program: 1) developing an alternative funding strategy, 2) developing a policy for early-infant (0-2 months) and early-adolescent (15-17 years) male circumcision, which is crucial to sustainable HIV prevention; and 3) identifying integrated and efficient implementation models. We formulated a framework showing how, in each phase, a range of behavioral dynamics can form barriers that hinder effective decision-making among stakeholders at the same level (e.g., national ministries and donors) or across levels (e.g., national, provincial and district). Our research methodology and the resulting framework offer a systematic approach for in-depth investigations into organizational decision-making in public health programs, as well as development programs beyond VMMC and HIV prevention. It provides the insights necessary to map organizational development and policy-making transition plans to sustainability, by explaining tangible factors such as organizational processes and systems, as well as intangibles such as the behaviors of policymakers and institutional actors.","PeriodicalId":504483,"journal":{"name":"Gates Open Research","volume":"118 42","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140088354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While there is a growing consensus that more financing and resources are needed to address these impacts, information on how to direct funding and support adaptation is dispersed and difficult to find. Agricultural development stakeholders and investors can leverage increasingly available data from a range of online sources to inform their climate smart agriculture investments, but it is not always clear which data tools are easily accessible and which can support different aspects of their programs. Methods This analysis aims to inform stakeholders how different tools can inform their climate smart investments. Hundreds of interactive tools were reviewed from multiple sources and a set of criteria was developed to simplify and elucidate the landscape of resources available that support adaptation and GHG mitigation for agricultural producers in low-income countries. The search strategy included a literature review, discussions with key stakeholders, and a review of existing databases of tools (e.g., NDC Partnership Toolbox). Results Ultimately 29 tools were identified and compared in terms of how they address both climate risk, adaptation, and mitigation. The data sources behind the tools were also compared, and illustrative user groups were identified. Many valuable, easy-to-use tools exist offering non-climate experts’ opportunities to gain insights into the relationship between climate and small-scale farming systems. However, the tools available are insufficient and should not be relied upon exclusively for informing investments. Conclusions This review provides a valuable resource for those looking to inform investments and programming in small-scale agriculture. This set of tools can provide insights that can be leveraged in various ways for a wide range of users, but they also have considerable limitations. This review can help users understand how these tools can be useful and the types of additional context-specific and local information that should be sought.","PeriodicalId":504483,"journal":{"name":"Gates Open Research","volume":" 535","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140092365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Improving calcium intake has benefits not only for bone health but also helps to prevent pregnancy hypertension disorders. Calcium concentration of tap water is usually low The aim of the present study was to determine the maximum amount of calcium that can be added to tap water while complying with drinking water local regulations. Methods Tap water samples were collected from the Province of Buenos Aires (Argentina). Physicochemical properties and saturation index were measured. Different incremental concentrations of calcium chloride were added to the experimental aliquots. Results Baseline water had a mean calcium concentration of 22.00 ± 2.54 mg/L, water hardness of 89.9 ± 6.4 mg/L CaCO3, and a saturation index of -1.50 ± 0.11. After the addition of 0.4554 ± 0.0071 g of salt, water hard-ness reached 355.0 ± 7.1 mg/L CaCO3, a calcium concentration of 140.50 ± 2.12 mg/L, and a saturation index -0.53 ± 0.02.
