RESUMEN
BACKGROUND: One-third of preschool children in Myanmar were stunted in 2015-2016, and three-quarters of children 6-23 mo had inadequate diet diversity. In response, a large-scale nutrition-sensitive social protection program was implemented over 2016-2019. In 2020, however, Myanmar's economy was hit hard by the COVID-19 pandemic and harder still by a military takeover in 2021. OBJECTIVE: The objective of this study was to examine whether former beneficiaries of this program experienced better food security, food consumption, and diet diversity outcomes in the wake of major economic shocks. METHODS: In a previous cluster-randomized controlled trial conducted over 2016-2019, pregnant women and their children aged <2 y were randomly assigned to either: 1) CASH; 2) CASH + social and behavioral change communication (SBCC); or 3) a control group. Subsamples of these former participants were then resurveyed 10 times from June 2020 to December 2021 during Myanmar's protracted economic crisis. Randomized treatment exposure was used in a regression analysis to test for postprogram impacts on Food Insecurity Experience Scale indicators, household food consumption, and maternal and child diet diversity. We also examined the impacts on household income as a secondary outcome and potential impact pathway. RESULTS: Both intervention arms reported lower food insecurity, more frequent consumption of nutritious foods, and more diverse maternal and child diets compared with households in the control group. However, the improved dietary outcomes were larger for mothers and children exposed to CASH+SBCC compared with CASH, as was their monthly household income. CONCLUSIONS: The findings suggest that a program combining cash transfers with nutrition-related education can yield sustained benefits 1-2 y after the program was completed. This strengthens the evidence to support the expansion and scale-up of nutrition-sensitive social welfare programs to redress chronic malnutrition and enhance nutritional resilience in the face of a severe economic crisis.

This paper uses novel micro-data on natural resources and administrative health data in Brazil to study how economic booms in minerals affect health at birth. By implementing a reduced-form estimation of shift-share research designs, the identification strategy relies on the exogeneity of global commodity prices to municipality-specific health outcomes. I find that, following changes in international prices, municipalities with historically more endowments have a higher number of premature births and births with low Appearance, Pulse, Grimace, Activity, Respiration scores. The impacts are primarily driven by metallic minerals. Instead, industrial minerals do not appear to have any effect on birth outcomes. Even though booms in metallic minerals generate benefits through resource windfalls-by increasing wealth and generating economic opportunities-the investigation of mechanisms reveals that they also result in costs-due to pollution-which seem to prevail. Hence, some metallic minerals remain a curse more than a blessing.

BACKGROUND: The entire population of Mozambique is at risk for malaria, which remains one of the leading causes of death. The 2017-2022 National Malaria Strategic Plan focuses on reducing malaria morbidity and mortality in high- and low-transmission areas. This study aimed to estimate the costs and health benefits of six variations of the World Health Organization's "test-and-treat" strategy among children under five. METHODS: A decision tree model was developed that estimates the costs and health outcomes for children under five. Data on probabilities, costs, weights for disability-adjusted life years (DALYs), and quality-adjusted life years (QALYs) were based on peer-reviewed, grey literature, and primary data analysis of the 2018 Malaria Indicator Survey. Six scenarios were compared to the status quo and calculated the incremental cost-effectiveness ratio (ICER) in terms of cost per QALY gained, DALY averted, and life saved. Deterministic and probabilistic sensitivity analyses were conducted to understand the effect of parameter uncertainty on the findings. RESULTS: In the base case, reaching the target of 100% testing with rapid diagnostic tests (RDTs; Scenario 1) is more cost-effective than improving the testing rate alone by 10% (Scenario 2). Achieving a 100% (Scenario 3) or a 10% increase in treatment rate (Scenario 4) have ICERs that are lower than Scenarios 1 and 2. Both Scenarios 5 and 6, which represent combinations of Scenarios 1-4, have lower ICERs than their constituent strategies on their own, which suggests that improvements in treatment are more cost-effective than improvements in testing alone. These results held when DALYs averted or lives saved were used as health outcomes. Deterministic and probabilistic sensitivity analyses revealed that the cost-effectiveness of Scenarios 1-6 are subject sensitive to parameter uncertainty, though Scenarios 4 and 5 are the optimal choice when DALYs averted or QALYs gained were used as the measure of health outcomes across all cost-effectiveness thresholds. CONCLUSIONS: Improving testing rates alone among children at risk for malaria has the potential to improve health but may not be the most efficient use of limited resources. Instead, small or large improvements in treatment, whether alone or in conjunction with improvements in testing, are the most cost-effective strategies for children under five in Mozambique.

BACKGROUND: Savings and Internal Lending Communities (SILCs) are a type of informal microfinance mechanism widely adapted in Zambia. The benefits of SILCs paired with other interventions have been studied in many countries. However, limited studies have examined SILCs in the context of maternal health. This study examined the association between having access to SILCs and: 1) household wealth, 2) financial preparedness for birth, and 3) utilization of various reproductive health services (RHSs). METHODS: Secondary analysis was conducted on baseline and endline household survey data collected as part of a Maternity Waiting Home (MWH) intervention trial in 20 rural communities across seven districts of Zambia. Data from 4711 women who gave birth in the previous year (baseline: 2381 endline: 2330) were analyzed. The data were stratified into three community groups (CGs): CG1) communities with neither MWH nor SILC, CG2) communities with only MWH, and CG3) communities with both MWH and SILC. To capture the community level changes with the exposure to SILCs, different women were randomly selected from each of the communities for baseline and endline data, rather than same women being surveyed two times. Interaction effect of CG and timepoint on the outcome variables - household wealth, saving for birth, antenatal care visits, postnatal care visits, MWH utilization, health facility based delivery, and skilled provider assisted delivery - were examined. RESULTS: Interaction effect of CGs and timepoint were significantly associated only with MWH utilization, health facility delivery, and skilled provider delivery. Compared to women from CG3, women from CG1 had lower odds of utilizing MWHs and delivering at health facility at endline. Additionally, women from CG1 and women from CG2 had lower odds of delivering with a skilled provider compared to women from CG3. CONCLUSION: Access to SILCs was associated with increased MWH use and health facility delivery when MWHs were available. Furthermore, access to SILCs was associated with increased skilled provider delivery regardless of the availability of MWH. Future studies should explore the roles of SILCs in improving the continuity of reproductive health services. TRIAL REGISTRATION: NCT02620436.

BACKGROUND: Although use of malaria diagnostic tests has increased in recent years, health workers often prescribe anti-malarial drugs to individuals who test negative for malaria. This study investigates how health worker adherence to malaria case management guidelines influences individuals' beliefs about whether their illness was malaria, and their confidence in the effectiveness of artemisinin-based combination therapy (ACT). METHODS: A survey was conducted with 2065 households in Western Kenya about a household member's treatment actions for a recent febrile illness. The survey also elicited the individual's (or their caregiver's) beliefs about the illness and about malaria testing and treatment. Logistic regressions were used to test the association between these beliefs and whether the health worker adhered to malaria testing and treatment guidelines. RESULTS: Of the 1070 individuals who visited a formal health facility during their illness, 82% were tested for malaria. ACT rates for malaria-positive and negative individuals were 89 and 49%, respectively. Overall, 65% of individuals/caregivers believed that the illness was "very likely" malaria. Individuals/caregivers had higher odds of saying that the illness was "very likely" malaria when the individual was treated with ACT, and this was the case both among individuals not tested for malaria [adjusted odds ratio (AOR) 3.42, 95% confidence interval (CI) [1.65 7.10], P = 0.001] and among individuals tested for malaria, regardless of their test result. In addition, 72% of ACT-takers said the drug was "very likely" effective in treating malaria. However, malaria-negative individuals who were treated with ACT had lower odds of saying that the drugs were "very likely" effective than ACT-takers who were not tested or who tested positive for malaria (AOR 0.29, 95% CI [0.13 0.63], P = 0.002). CONCLUSION: Individuals/caregivers were more likely to believe that the illness was malaria when the patient was treated with ACT, regardless of their test result. Moreover, malaria-negative individuals treated with ACT had lower confidence in the drug than other individuals who took ACT. These results suggest that ensuring health worker adherence to malaria case management guidelines will not only improve ACT targeting, but may also increase patient/caregivers' confidence in malaria testing and treatment.

As part of a randomized controlled trial conducted in Myanmar between 2016 and 2019, we explore the performance of a maternal cash transfer program across villages assigned to different models of delivery (by government health workers vs loan agents of a non-governmental organization) and identify key factors of success. Measures include enrolment inclusion and exclusion errors, failures in payment delivery to enrolled beneficiaries (whether beneficiaries received any transfer, fraction of benefits received and whether there were delays and underpayment of benefit amounts) and whether beneficiaries remained in the program beyond eligibility. We find that women in villages where government health workers delivered cash transfers received on average two additional monthly transfers, were 19.7% more likely to receive payments on time and in-full and were 14.6% less likely to stay in the program beyond eligibility. With respect to the primary health objective of the program-child nutrition-we find that children whose mother received cash by government health workers were less likely to be chronically malnourished compared to those whose mother received cash by loan agents. Overall, the delivery of cash transfers to mothers of young children by government health workers outperforms the delivery by loan agents in rural Myanmar. Qualitative evidence suggests two key factors of success: (1) trusted presence and past interactions with targeted beneficiaries and complementarities between government health workers' expertise and the program; and (2) performance incentives based on specific health objectives along with top-down monitoring. We cannot exclude that other incentives or intrinsic motivation also played a role.

Microbial communities inhabiting the Antarctic Ocean show psychrophilic and halophilic adaptations conferring interesting properties to the enzymes they produce, which could be exploited in biotechnology and bioremediation processes. Use of cold- and salt-tolerant enzymes allows to limit costs, reduce contaminations, and minimize pretreatment steps. Here, we report on the screening of 186 morphologically diverse microorganisms isolated from marine biofilms and water samples collected in Terra Nova Bay (Ross Sea, Antarctica) for the identification of new laccase activities. After primary screening, 13.4 and 10.8% of the isolates were identified for the ability to oxidize 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and the dye azure B, respectively. Amongst them, the marine Halomonas sp. strain M68 showed the highest activity. Production of its laccase-like activity increased six-fold when copper was added to culture medium. Enzymatic activity-guided separation coupled with mass spectrometry identified this intracellular laccase-like protein (named Ant laccase) as belonging to the copper resistance system multicopper oxidase family. Ant laccase oxidized ABTS and 2,6-dimethoxy phenol, working better at acidic pHs The enzyme showed a good thermostability, with optimal temperature in the 40-50°C range and maintaining more than 40% of its maximal activity even at 10°C. Furthermore, Ant laccase was salt- and organic solvent-tolerant, paving the way for its use in harsh conditions. To our knowledge, this is the first report concerning the characterization of a thermo- and halo-tolerant laccase isolated from a marine Antarctic bacterium.
RESUMEN
We combine data on beliefs about the origin of the 2014 Ebola outbreak with two supervised machine learning methods to predict who is more likely to be misinformed. Contrary to popular beliefs, we uncover that, socio-demographic and economic indicators play a minor role in predicting those who are misinformed: misinformed individuals are not any poorer, older, less educated, more economically distressed, more rural, or ethnically different than individuals who are informed. However, they are more likely to report high levels of distrust, especially towards governmental institutions. By distinguishing between types of beliefs, distrust in the central government is the primary predictor of individuals assigning a political origin to the epidemic, while Muslim religion is the most important predictor of whether the individual assigns a supernatural origin. Instead, educational level has a markedly higher importance for ethnic beliefs. Taken together, the results highlight that government trust might play the most important role in reducing misinformation during epidemics.
RESUMEN
AIM: To assess the direct and opportunity costs involved in utilising maternity waiting homes. METHOD: A cross-sectional admission survey administered to women who used ten maternity waiting homes across two rural districts in Zambia. A total of 3,796 women participated in the survey. Descriptive analysis was conducted on three domains of the data: demographic characteristics of women, direct costs, and opportunity costs. FINDINGS: Waiting to deliver (86.3%), safe birth (70.8%), and distance (56.0%) were the most frequent reasons women reported for using a maternity waiting home. In terms of direct costs, roughly 65% of the women brought seven days or fewer days' worth of food to the maternity waiting homes, with salt, mealie meals, and vegetables being the most frequently brought items. Only 5.8% of the women spent money on transport. More than half of the women reported paying user fees that ranged from 1 to 5 or more kwacha (US$0.10- 0.52). In terms of opportunity costs, 52% of the women participated in some form of income generating activities (IGAs) when at home. Approximately 35% of the women reported they lost earned income (1 to 50 or more kwacha) by staying at a maternity waiting home. CONCLUSION: A large proportion of women paid for food and user fees to access a maternity waiting home, while a low number of women paid for transport. Even though it is difficult to assign monetary value to women's household chores, being away from these responsibilities and the potential loss of earned income appear to remain a cost to accessing maternity waiting homes. More research is needed to understand how to overcome these financial constraints and assist women in utilising a maternity waiting home.

Savings and Internal Lending Communities (SILCs) are a type of informal microfinance mechanism adapted in many low- and middle-income countries (LMICs) to improve financial resources for poor and rural communities. Although SILCs are often paired with other health and non-health-related interventions, few studies have examined SILCs in the context of maternal health. This study examined the association between SILC participation, household wealth and financial preparedness for birth. The study also examined the association between sex and financial preparedness for birth. A secondary analysis was conducted on individual survey data collected from SILC participants in two rural districts of Zambia between October 2017 and February 2018. A convenience sample of 600 participants (Lundazi: n = 297; Mansa: n = 303) was analysed. Descriptive analyses were run to examine SILC participation and household wealth. Multiple binary logistic regression models were fit to assess the unadjusted and adjusted relationship between (1) SILC participation and household wealth, (2) SILC participation and financial preparedness for birth and (3) sex and financial preparedness for birth. The results show that SILC participation led to an average increase of 7.32 items of the 13 household wealth items. SILC participants who had their most recent childbirth after joining SILCs were more likely to be financially prepared for birth [adjusted odds ratio (AOR): 2.99; 95% confidence interval (95% CI): 1.70-5.26; P < 0.001] than participants who had their most recent childbirth before joining SILCs. Females were more likely to be financially prepared for birth than males if they had their most recent birth before joining an SILC (AOR: 1.79; 95% CI: 1.16-2.66; P < 0.01). SILC participation is shown to increase household wealth and financial preparedness for birth for both men and women. SILCs are a promising intervention that can help poor and rural populations by increasing financial resources and financially preparing parents for birth.

This article describes similarities and differences in the response of governments and the international community to the current 2019 coronavirus disease (COVID-19) and the 2014 West African Ebola epidemic. It expresses the opinion that the speed and scale of the response to COVID-19 are affected by the important role that China plays in the global economy. By contrast, insufficient and less timely action was initially undertaken in West African countries during the 2014 Ebola epidemic. It concludes by stating why preparedness for and response to all disease outbreaks, also in countries of lower economic importance, should become a priority in the global health agenda.

A major puzzle in malaria treatment remains the dual problem of underuse and overuse of malaria medications, which deplete scarce public resources used for subsidies and lead to drug resistance. One explanation is that health behaviour, especially in the context of incomplete information, could be driven by beliefs, pivotal to the success of health interventions. The objective of this study is to investigate how population beliefs change in response to an experimental intervention which was shown to improve access to rapid diagnostic testing (RDT) through community health workers (CHWs) and to increase appropriate use of anti-malaria medications. By collecting data on individuals' beliefs on malaria testing and treatment 12 and 18 months after the experimental intervention started, we find that the intervention increases the belief that a negative test result is correct, and the belief that the first-line anti-malaria drugs (artemisinin-based combination therapies or ACTs) are effective. Using mediation analysis, we also explore some possible mechanisms through which the changes happen. We find that the experience and knowledge about RDT and experience with CHWs explain 62.4% of the relationship between the intervention and the belief that a negative test result is correct. Similarly, the targeted use of ACTs and taking the correct dose-in addition to experience with RDT-explain 96.8% of the relationship between the intervention and the belief that the ACT taken is effective. As beliefs are important determinants of economic behaviour and might guide individuals' future decisions, understanding how they change after a health intervention has important implications for long-term changes in population behaviour.

When making decisions under uncertainty, individuals may form subjective expectations about probabilities of events relevant for their choice. Accurate measurement of subjective expectations is critical for high-quality data needed to analyze individual behavior. This paper reports the development and validity of a new method of eliciting point subjective expectations in developing countries. We developed a touchscreen-based application that combines an animated slider along with dynamic images that change relative sizes based on the probability indicated by the respondent. We compare our method to the more traditional approach of using beans as visual aids. First, we find that respondents have a sound understanding of basic concepts of probability. Second, we test for equality of the distributions elicited with the different methods and find them highly comparable. Third, we provide evidence that respondents report a more favorable opinion about the slider method and more willingness to complete long surveys using the slider rather than beans. Our findings suggest that the slider could be a viable elicitation method for empirical researchers who aim to collect data on subjective expectations in developing countries.

In many developing countries, male circumcision has been promoted as an effective HIV prevention strategy, and medical randomized controlled trials have indeed shown a causal link. However, there is limited empirical evidence to support this conclusion in countries where individuals can voluntary opt for different types of circumcision. The present study considers male circumcision in Lesotho, where HIV prevalence is among the highest in the world (23%). Here, men can opt for one of two types of circumcision: traditional male circumcision in initiation schools, or the medical option in health clinics. This paper investigates whether the former has medical effects on individual HIV status that are as beneficial as those shown for the latter. Controlling for the potential individual behavioral response after the operation, it was found that circumcision performed in initiation schools wholly offset the medical benefits of the surgical procedure. This supports anecdotal evidence that the operation performed by traditional circumcisers does not have the same protective effect against HIV transmission as the medical operation. No evidence of "disinhibition" behavior among circumcised men was found, nor differential risky sexual behavior among men circumcised, traditionally or medically. Considering that, in Lesotho, traditional male circumcision is undertaken by more than 90% of circumcised men, the findings highlight the need for further research into how the operation in initiation schools is performed and its medical benefits.
