Confirming-and testing-bonds of trust: A mixed methods study exploring community health workers' experiences during the COVID-19 pandemic in Bangladesh, Haiti and Kenya.

Amidst the COVID-19 pandemic and national responses, trust (one's belief that a system acts in one's best interest) is important to consider. In community health systems, trust is embedded in relationships between clients, CHWs, and health system stakeholders. This mixed-methods study explores trust through the evolving COVID-19 crisis in Bangladesh, Haiti, and Kenya, where multi-country community health research was underway.

This study explored the roles and perspectives of CHWs within the government-led coronavirus disease (COVID-19) community health response in Bangladesh.

Methods: We conducted a mixed methods study to explore the government's response to COVID-19 and its association with community health programming through a telephone-based survey of 370 government-employed CHWs.

Review of Nitrification Monitoring and Control Strategies in Drinking Water System.

Nitrification is a major challenge in chloraminated drinking water systems, resulting in undesirable loss of disinfectant residual. Consequently, heterotrophic bacteria growth is increased, which adversely affects the water quality, causing taste, odour, and health issues. Regular monitoring of various water quality parameters at susceptible areas of the water distribution system (WDS) helps to detect nitrification at an earlier stage and allows sufficient time to take corrective actions to control it.

Development of an Optical Method to Monitor Nitrification in Drinking Water.

Nitrification is a common issue observed in chloraminated drinking water distribution systems, resulting in the undesirable loss of monochloramine (NHCl) residual. The decay of monochloramine releases ammonia (NH), which is converted to nitrite (NO) and nitrate (NO) through a biological oxidation process. During the course of monochloramine decay and the production of nitrite and nitrate, the spectral fingerprint is observed to change within the wavelength region sensitive to these species.

The Client Empowerment in Community Health Systems Scale: Development and validation in three countries.

Background: Effectively measuring client empowerment is critical for monitoring and supporting empowerment through interventions, including via community health workers (CHWs) on the front line. Yet a comprehensive measure capturing the multidimensional aspects of client empowerment is not currently available. We aimed to develop and validate the Client Empowerment in Community Health Systems (CE-CHS) Scale in three countries.

Measuring client trust in community health workers: A multi-country validation study.

Background: Client trust in community health workers (CHWs) is integral for improving quality and equity of community health systems globally. Despite its recognized conceptual and pragmatic importance across health areas, there are no quantitative measures of trust in the context of community health services. In this multi-country study, we aimed to develop and validate a scale that assesses trust in CHWs.

Development and validation of a multi-dimensional scale to assess community health worker motivation.

Background: Ensuring that Community Health Workers (CHWs) are motivated is critical to their performance, retention and well-being - and ultimately to the effectiveness of community health systems worldwide. While CHW motivation is as multi-dimensional construct, there is no multi-dimensional measure available to guide programming. In this study, we developed and validated a pragmatic, multi-dimensional measure of CHW motivation.

Measuring quality of care at the community level using the contraceptive method information index plus and client reported experience metrics in Bangladesh.

Background: Low rates of contraceptive continuation in Bangladesh are a symptom of poor quality family planning (FP) counseling. Improving family planning counseling by the country's community health care workers (CHWs) could improve contraceptive continuation. This study explores client experiences of care from CHWs, as measured by the method information index plus (MII+) and communication quality metric.

Pathways to service access for pre-eclampsia and eclampsia in rural Bangladesh: Exploring women's care-seeking.

Background: While women in low- and middle-income countries face a range of barriers to accessing care for hypertensive disorders of pregnancy, there is little understanding of the pathways taken to overcome these constraints and reach the services they need. This study explores the perspectives of women and communities on the influences that impact care-seeking decisions and pathways to health services.

Methods: To understand individual perspectives, we conducted 22 in-depth interviews (IDIs) with pre-eclampsia and eclampsia survivors (PE/E) in a tertiary hospital, where they received care after initiating PE/E services in different parts of the country.

Spectrophotometric Online Detection of Drinking Water Disinfectant: A Machine Learning Approach.

The spectra fingerprint of drinking water from a water treatment plant (WTP) is characterised by a number of light-absorbing substances, including organic, nitrate, disinfectant, and particle or turbidity. Detection of disinfectant (monochloramine) can be better achieved by separating its spectra from the combined spectra. In this paper, two major focuses are (i) the separation of monochloramine spectra from the combined spectra and (ii) assessment of the application of the machine learning algorithm in real-time detection of monochloramine.

Knowledge of pharmacy workers on antihypertensive and anticonvulsant drugs for managing pre-eclampsia and eclampsia in Bangladesh.

Background: Pharmacy workers in Bangladesh play an important role in managing pregnancy complications by dispensing, counselling and selling drugs to pregnant women and their families. This study examined pharmacy workers' drug knowledge and practice for pre-eclampsia and eclampsia (PE/E) management, including antihypertensives and anticonvulsants, and determine factors associated with their knowledge.

Methods: A cross-sectional survey with 382 pharmacy workers in public facilities (government) and private pharmacies and drug stores assessed their knowledge of antihypertensive and anticonvulsant drugs.

A primary health care model for managing pre-eclampsia and eclampsia in low- and middle- income countries.

Background: Hypertensive disorders in pregnancy, specifically pre-eclampsia and eclampsia (PE/E), are the second biggest killer of pregnant women globally and remains the least understood and most challenging maternal morbidity to manage. Although great strides were made in reducing maternal and newborn mortality between 1990 and 2015, this was clearly not enough to achieve the global health goals. To reduce maternal deaths: 1) early detection of PE needs to be improved; 2) effective management of PE/E needs to occur at lower health system levels and should encourage timely care-seeking; and 3) prioritizing the scale up of a comprehensive package of services near to where women live.

Understanding incentive preferences of community health workers using discrete choice experiments: a multicountry protocol for Kenya, Uganda, Bangladesh and Haiti.

Introduction: There is a renewed global interest in improving community health worker (CHW) programmes. For CHW programmes to be effective, key intervention design factors which contribute to the performance of CHWs need to be identified. The recent WHO guidelines recommends the combination of financial and non-financial incentives to improve CHW performance.

Investigation of the Antibacterial Activity and Cytotoxicity of Biogenic Silver Nanoparticles as Potent Therapeutics.

Biogenic nanoparticles are the smartest weapons to deal with the multidrug-resistant "superbugs" because of their broad-spectrum antibacterial propensity as well as excellent biocompatibility. The aqueous biogenic silver nanoparticles (Aq-bAgNPs) and ethanolic biogenic silver nanoparticles (Et-bAgNPs) were synthesized using aqueous and ethanolic extracts of stem, respectively, as reducing agents. Electron microscopic images confirmed the synthesis of almost spherical shaped biogenic silver nanoparticles (bAgNPs).
