Numerical Investigation on the Structural Behavior of a Short-Span Cable-Stayed Bridge with Steel and CFRP Hybrid Cables.

In this paper, a thorough investigation is presented on the static and dynamic behaviors of a short-span cable-stayed bridge (CSB) incorporating steel and carbon fiber reinforced polymer (CFRP) hybrid cables. The study focuses on the world's largest span and China's first highway, CFRP CSB. The performance of the CSB was compared using numerical simulations under four different cable patterns: steel cables, CFRP cables, and steel, and two types of hybrid cables with different structural arrangements. The results indicate that the use of the use of CFRP cables in the long cable region in the short-span CSB project investigated in this study offers improved performance in terms of stability, seismic response, and reduced displacements. In comparison to CFRP cables, hybrid cables have demonstrated a reduction of 12% in the maximum vertical displacement of the main girder. On the other hand, the hybrid cables result in reduced maximum internal forces and longitudinal and lateral displacements of the main girders and towers compared to steel cables. The difference in the arrangement of CFRP cables in the long cable region or short cable region is not obvious under dead loads, but significant differences still exist between the CFRP cable bridges in the short cable region and the long cable region in terms of live load effects, temperature effects, and dynamic characteristics.

Associations between parental adherence to healthy lifestyles and cognitive performance in offspring: A prospective cohort study in China.

BACKGROUND: Previous studies have reported associations of specific maternal and paternal lifestyle factors with offspring's cognitive development during early childhood. This study aimed to investigate the prospective associations between overall parental lifestyle and offspring's cognitive performance during adolescence and young adulthood in China. METHODS: We included 2531 adolescents aged 10-15 years at baseline in 2010 from the China Family Panel Studies. A healthy parental lifestyle score (ranged 0-5) was constructed based on the following five modifiable lifestyle factors: Smoking, drinking, exercise, sleep, and diet. Generalized estimating equation models were used to examine the association between baseline parental healthy lifestyle scores and offspring's fluid and crystallized intelligence in subsequent years (2012, 2014, 2016, and 2018). RESULTS: Offspring in the top tertile of parental healthy lifestyle scores performed better in overall fluid intelligence (multivariable-adjusted ß = 0.53, 95% confidence interval [CI]: 0.29-0.77) and overall crystallized intelligence (multivariable-adjusted ß = 0.35, 95% CI: 0.16-0.54) than those in the bottom tertile of parental healthy lifestyle scores. The results were similar after further adjustment for the offspring's healthy lifestyle scores and persisted across the subgroups of parental socioeconomic status. Additionally, maternal and paternal healthy lifestyle scores were independently associated with better offspring's cognitive performance, with significant contribution observed for paternal never-smoking, weekly exercise, and diversified diet. When both parents and offspring adhered to a healthier lifestyle, we observed the highest level of the offspring's overall crystallized intelligence. CONCLUSIONS: Our study indicates that parental adherence to a healthier lifestyle is associated with significantly better offspring's cognitive performance during adolescence and early adulthood, regardless of socioeconomic status. These findings highlight the potential cognitive benefits of promoting healthy lifestyles among parents of adolescents.

The association of a disability-targeted cash transfer programme with disability status and health-care access: a quasi-experimental study using a nationwide cohort of 4·3 million Chinese adults living with severe disabilities.

BACKGROUND: Cash transfer is a crucial policy tool to address inequality. The objective of this study was to investigate the association between China's disability-targeted cash transfer programme and disability status, as well as equitable access to rehabilitation and medical services. METHODS: For this quasi-experimental study, we drew data from the nationwide administrative cohort of individuals with disabilities between Jan 1, 2015, and Dec 31, 2019. Individuals were enrolled in the cohort if they were aged 18 years or older, had severe disabilities as defined by the Chinese Government, and had available cash transfer information for at least 4 consecutive years, without having started receiving cash transfer benefits at the time of enrolment. We used a quasi-experimental design with propensity score matching to estimate the effects of cash transfers on disability status, access to rehabilitation services, and access to medical treatment. The primary outcomes were development of new disability and reduction of existing disabilities. Secondary outcomes were use of rehabilitation services, financial barriers as a major obstacle to accessing rehabilitation services, use of medical services by individuals who had an illness in the previous 2 weeks, and financial barriers as a major obstacle to accessing medical services. FINDINGS: From an initial pool of 51 356 125 individuals with disabilities registered in the administrative system, 2 686 024 individuals were eligible for analysis, of whom 2 165 335 (80·6%) were cash transfer beneficiaries and 520 689 (19·4%) non-beneficiaries. After propensity score matching, the cohort included 4 330 122 adults with severe disabilities. Cash transfer beneficiaries had significantly lower odds of developing new disabilities over time than non-beneficiaries (odds ratio [OR] 0·90, 95% CI 0·86-0·94; p<0·0001) and higher odds of having a reduced number of disabilities over time (1·17, 1·10-1·25; p<0·0001). Compared with non-beneficiaries, cash transfer beneficiaries were more likely to use rehabilitation services (2·12, 2·11-2·13; p<0·0001) and medical services (1·74, 1·69-1·78; p<0·0001), and less likely to report financial hardship to access rehabilitation services (0·53, 0·52-0·54; p<0·0001) and medical services (0·88, 0·84-0·93; p<0·0001) at the study endpoint. INTERPRETATION: The receipt of cash transfers was associated with improved disability status and increased access to disability-related services. The findings suggest that cash transfers could be a potential method for promoting universal health coverage among individuals living with disabilities.

Prevalence and changes of intimate partner violence against women aged 15 to 49 years in 53 low-income and middle-income countries from 2000 to 2021: a secondary analysis of population-based surveys.

BACKGROUND: In low-income and middle-income countries (LMICs), intimate partner violence poses a substantial barrier to accomplishing target 5.2 of the Sustainable Development Goals: to eliminate all forms of violence against women and girls. Our study aimed to assess the prevalence and changes of intimate partner violence against women in LMICs. We also explored the association between women's empowerment and intimate partner violence. METHODS: In this secondary analysis of population-based surveys, we obtained data from the nationally representative Demographic and Health Surveys conducted in LMICs between 2000 and 2021. We selected countries with available data on the domestic violence module, and women aged 15 to 49 years who currently or formerly had a husband or partner, and who had provided information about intimate partner violence, were included in the analysis. We first estimated the weighted prevalence of intimate partner violence in LMICs with available data, and then we assessed the average annual rate of change using Poisson regression with robust error variance in a subset of countries with at least two surveys. We used multilevel analysis to investigate the association between intimate partner violence and women's empowerment measured at both the country and individual levels. Country-level empowerment was measured by gender inequality index, while individual-level empowerment considered social independence, decision making, and attitude to violence. FINDINGS: A total of 359 479 women aged 15 to 49 years were included from 53 LMICs. 336 811 women from 21 countries with two surveys provided data for assessing the trends of intimate partner violence. The weighted prevalence of any type of intimate partner violence was 37·2% (95% CI 36·6 to 37·8). A significant overall decline in the prevalence of any type of intimate partner violence was observed with an average annual rate of change of -0·2% (95% CI -0·4 to -0·03); however six countries showed significant increasing trends, with average annual rates of change ranging from 1·2% (95% CI 0·7 to 1·7) in Nigeria to 6·6% (5·3 to 7·8) in Sierra Leone. Notably, the prevalence of psychological intimate partner violence has risen (average annual rate of change, 2·3% [95% CI 2·1 to 2·6]), reflected in increased rates across eight countries. Higher levels of country-level women's empowerment were associated with a lower risk of intimate partner violence: women from countries with the highest tertile of gender inequality index had an increased odds of any type of intimate partner violence (odds ratio 1·58 [95% CI 1·12 to 2·23]). Similarly, better individual-level women's empowerment also showed significant associations with a lower risk of intimate partner violence. INTERPRETATION: The prevalence of intimate partner violence remains high, and some countries have shown an increasing trend. The strong relationship between both country-level and individual-level women's empowerment and the prevalence of intimate partner violence suggests that accelerating women's empowerment could be one strategy to further reduce intimate partner violence against women.

Financial burden of prostate cancer in the Iranian population: a cost of illness and financial risk protection analysis.

BACKGROUND: Prostate cancer is the second most common cancer in males worldwide and the third most common among Iran's male population. However, there is a lack of evidence regarding its direct and indirect costs in low and middle-income countries. This study intends to bridge the gap using a cost of illness approach, assessing the costs of prostate cancer from the perspectives of patients, society, and the insurance system. METHODS: Two hundred ninety seven patients were included in the study. Data for a 2-month period were obtained from patients registered at two hospitals (Tabriz, Tehran) in Iran in 2017. We applied a prevalence-based, bottom-up approach to assess the costs of the illness. We used the World Health Organization methods to measure the prevalence and investigate the determinants of catastrophic and impoverishing health expenditures. RESULTS: We determined the total costs of the disease for the patients to be IRR 68 million (PPP $ 5,244.44). Total costs of the disease from the perspective of the society amounted to IRR 700,000 million (PPP $ 54 million). Insurance companies expended IRR 20 million (PPP $ 1,558.80) per patient. Our findings show that 31% of the patients incurred catastrophic health expenditure due to the disease. Five point forty-four percent (5.44%) of the patients were impoverished due to the costs of this cancer. CONCLUSION: We found an alarmingly high prevalence of catastrophic health expenditures among prostate cancer patients. In addition, prostate cancer puts a substantial burden on both the patients and society.

Assessing household financial burdens for preprimary education and associated socioeconomic inequalities: a case study in China.

BACKGROUND: Providing young children with universal access to preprimary education (PPE) is considered a powerful tool for human capital development and eliminating the intergenerational transmission of poverty. To remove household financial barrier for achieving universal PPE, this study proposed a measure to identify households incurring 'heavy financial burdens from paying for PPE' (HBPPE) and conducted a case study in China. METHODS: Using nationally representative data in 2019, we estimated the percentage of households with HBPPE (spent 7% or more of their total annual expenditure) and associated socioeconomic inequalities. We also applied a three-level logit regression model to investigate the factors associated with the probabilities of households incurring HBPPE. RESULTS: Half of the sampled households spent 7% or more of their expenditures on PPE. Households in the lowest wealth quintile (54%) or households with children attending private PPE (55%) had higher percentages of HBPPE than households in other wealth quintiles (eg, 51% in the highest wealth quintile) or households with children attending public kindergartens (41%). Logit regression analysis shows that the poorest households and households with children attending private kindergarten were more likely to incur HBPPE than their counterparts. CONCLUSION: To ensuring universal access to PPE in China, future policy should consider increasing the enrolment of children from low-income families in public kindergartens and increasing governmental investments in low-income households by subsidising children attending PPE.

Development of a flat conical chamber-based non-dispersive infrared CO2 gas sensor with temperature compensation.

In order to accurately monitor CO2 concentration based on the non-dispersive infrared technique, a novel flat conical chamber CO2 gas sensor is proposed and investigated by simulation analysis and experimental verification. First, the optical design software and computational fluid dynamics method are utilized to theoretically investigate the relationship between the energy distribution, absorption efficiency of infrared radiation, and chamber size. The simulation results show that the chamber length has an optimal value of 8 cm when the cone angle is 5° and the diameter of the detection surface is 1 cm, which makes infrared absorption efficiency optimal. Then, the flat conical chamber CO2 gas sensor system is developed, calibrated, and tested. The experimental results indicate that the sensor can accurately detect CO2 gas concentrations in the range of 0-2000 ppm at 25 °C. It is found that the absolute error of calibration is within 10 ppm, and the maximum repeatability and stability errors are 5.5 and 3.5%, respectively. Finally, the genetic neural network algorithm is presented to compensate for the output concentration of the sensor to solve the problem of temperature drift. Experimental results demonstrate that the relative error of the compensated CO2 concentration is varied from -0.85 to 2.32%, which is significantly reduced. The study has reference significance for the structural optimization of the infrared CO2 gas sensor and the improvement of the measurement accuracy.

Family play, reading, and other stimulation and early childhood development in five low-and-middle-income countries.

This paper used longitudinal data from five studies conducted in Bangladesh, Bhutan, Cambodia, Ethiopia, and Rwanda to examine the links between family stimulation and early childhood development outcomes (N = 4904; Mage = 51.5; 49% girls). Results from random-effects and more conservative child-fixed effects models indicate that across these studies, family stimulation, measured by caregivers' engagement in nine activities (e.g., reading, playing, singing), predicted increments in children's early numeracy, literacy, social-emotional, motor, and executive function skills (standardized associations ranged from 0.05 to 0.11 SD). Study-specific models showed variability in the estimates, with null associations in two out of the five studies. These findings indicate the need for additional research on culturally specific ways in which caregivers may support early development and highlight the importance of promoting family stimulation to catalyze positive developmental trajectories in global contexts. RESEARCH HIGHLIGHTS: Research on the links between family stimulation and early childhood development in low-and-middle-income countries (LMICs) is limited. We used longitudinal data from studies conducted in five LMICs to examine the links between family stimulation and early childhood development outcomes. Results suggest that family stimulation predicted increments in children's numeracy, literacy, social-emotional, motor, and executive function skills. We found variability in the observed estimates, with null associations in two out of the five studies, suggesting the need for additional research in LMICs.

The effect of a disability-targeted cash transfer program on universal health coverage and universal access to education: a nationwide cohort study of Chinese children and adolescents with disabilities.

Background: To achieve improved outcomes for children and adolescents with disabilities, it is central to have universal health coverage (UHC) and universal access to education. This study investigates whether a disability-targeted cash transfer (CT) program is associated with improved access to healthcare and education for children and adolescents with disabilities. Methods: We used nationwide survey data of two million children and adolescents living with disabilities, who aged 8-15 years when entering the cohort between January 1, 2015, and December 31, 2019. With a quasi-experimental study design, we compared the outcomes between CT beneficiaries who newly received CT benefits during the study period and non-beneficiaries who were disabled but never received CT using logistic regressions after propensity score matching with a 1:1 ratio. Outcomes of interest were utilization of rehabilitation services in the past year, medical treatment if the individual had illness in the past two weeks, school attendance if not in school at the start of the study, and reported financial hardship to access these services. Findings: Of the total cohort, 368,595 children and adolescents fit the inclusion criteria, including 157,707 new CT beneficiaries and 210,888 non-beneficiaries. After matching, CT beneficiaries showed 2.27 (95% confidence interval [CI]: 2.23, 2.31) higher odds of utilizing rehabilitation services and 1.34 (95% CI: 1.23, 1.46) higher odds of getting medical treatment compared to non-beneficiaries. CT benefits were also significantly associated with less report of financial barrier to access rehabilitation services (odds ratio [OR]: 0.63, 95% CI: 0.60, 0.66) and medical treatment (OR: 0.66, 95% CI: 0.57, 0.78). Moreover, CT program was associated with higher odds of school attendance (OR: 1.99, 95% CI: 1.85, 2.15) and lower odds of reporting financial difficult to access education (OR: 0.41, 95% CI: 0.36, 0.47). Interpretation: Our results suggest that the receipt of CT was associated with improved access to health and educational resources. This finding provides supporting evidence for the identification of efficient and feasible interventions to move toward UHC and universal education under the Sustainable Development Goals.

Tracking Population-Level Anxiety Using Search Engine Data: Ecological Study.

BACKGROUND: Anxiety disorders are the most prevalent mental disorders globally, with a substantial impact on quality of life. The prevalence of anxiety disorders has increased substantially following the COVID-19 pandemic, and it is likely to be further affected by a global economic recession. Understanding anxiety themes and how they change over time and across countries is crucial for preventive and treatment strategies. OBJECTIVE: The aim of this study was to track the trends in anxiety themes between 2004 and 2020 in the 50 most populous countries with high volumes of internet search data. This study extends previous research by using a novel search-based methodology and including a longer time span and more countries at different income levels. METHODS: We used a crowdsourced questionnaire, alongside Bing search query data and Google Trends search volume data, to identify themes associated with anxiety disorders across 50 countries from 2004 to 2020. We analyzed themes and their mutual interactions and investigated the associations between countries' socioeconomic attributes and anxiety themes using time-series linear models. This study was approved by the Microsoft Research Institutional Review Board. RESULTS: Query volume for anxiety themes was highly stable in countries from 2004 to 2019 (Spearman r=0.89) and moderately correlated with geography (r=0.49 in 2019). Anxiety themes were predominantly long-term and personal, with "having kids," "pregnancy," and "job" the most voluminous themes in most countries and years. In 2020, "COVID-19" became a dominant theme in 27 countries. Countries with a constant volume of anxiety themes over time had lower fragile state indexes (P=.007) and higher individualism (P=.003). An increase in the volume of the most searched anxiety themes was associated with a reduction in the volume of the remaining themes in 13 countries and an increase in 17 countries, and these 30 countries had a lower prevalence of mental disorders (P<.001) than the countries where no correlations were found. CONCLUSIONS: Internet search data could be a potential source for predicting the country-level prevalence of anxiety disorders, especially in understudied populations or when an in-person survey is not viable.

Association Between Parental Education and Simultaneous Malnutrition Among Parents and Children in 45 Low- and Middle-Income Countries.

Importance: Parental education is known to be associated with the health status of parents and their offspring. However, the association between parental education and the simultaneous manifestation of multiple forms of malnutrition within households remains underinvestigated globally. Objective: To assess the association between parental education and the simultaneous manifestation of malnutrition of both parent and child (either overnutrition or undernutrition)-referred to as the double burden of malnutrition (DBM)-at the household level in mother-child and father-child pairs in low- and middle-income countries (LMICs). Design, Setting, and Participants: This cross-sectional study used data from the US Agency for International Development Demographic and Health Surveys (January 1, 2010, to December 31, 2021) to identify mother-child pairs and father-child pairs from LMICs. The eligibility criteria were as follows: (1) children aged 0 to 59 months; (2) nonpregnant mothers at the time of the survey in the sample of mother-child pairs; and (3) valid measures of the weight, height, and hemoglobin level for the child and at least 1 of their parents. Exposures: Highest level of parental education obtained and number of years of education completed. Main Outcomes and Measures: Four sets of multivariable logistic regression models were constructed to assess the association between parental education and DBM, and analysis was performed between March 10 and May 15, 2022. Results: This study included 423 340 mother-child pairs from 45 LMICs and 56 720 father-child pairs from 16 LMICs. The mean (SD) age of the mother-child pairs was 28.2 (6.1) and 1.9 (1.4) years, respectively; 48.8% of the children were female. We observed that 49.0% of mother-child pairs experienced DBM. Compared with mother-child pairs with no maternal education, higher maternal education was associated with a lower risk of DBM. For example, the odds ratio (OR) for tertiary maternal education was 0.71 (95% CI, 0.67-0.74). However, the association differed by DBM subtypes: higher maternal education was associated with a lower risk of both mothers and children being undernourished but with a higher risk of almost all DBM subtypes involving overnutrition. For example, compared with mother-child pairs with no maternal education, those with secondary education were less likely to develop simultaneous maternal and child undernutrition (OR, 0.83 [95% CI, 0.80-0.86]) but were more likely to experience simultaneous maternal and child overnutrition (OR, 2.20 [95% CI, 1.61-3.00]); similar results were observed for pairs with primary and tertiary education. The results in mother-child pairs remained consistent after controlling for paternal education. Among the father-child pairs, 26.5% had DBM, with fathers with tertiary education significantly more likely to experience simultaneous paternal overnutrition and child undernutrition (OR, 1.55 [95% CI, 1.23-1.95]) compared with pairs with no paternal education; they were also less likely to have both paternal and child undernutrition (OR, 0.70 [95% CI, 0.59-0.84]). Conclusions and Relevance: In this study, maternal education and paternal education were independently associated with DBM, and the associations differed by DBM subtypes. These findings suggest that the different risks of malnutrition faced by households with various levels of education should thus be considered in policy evaluation.

Independent and cumulative effects of risk factors associated with stillbirths in 50 low- and middle-income countries: A multi-country cross-sectional study.

Background: Early identification of high-risk pregnancies could reduce stillbirths, yet remains a challenge in low- and middle-income countries (LMICs). This study aims to estimate the associations between easily observable risk factors and stillbirths, and construct a risk score which could be adopted in LMICs to identify pregnancies with high risk of stillbirths. Methods: Using the most recent Demographic and Health Surveys from 50 low- and middle-income countries (LMICs) with available data between January 1, 2010 and December 31, 2021, we analysed a total of 22 factors associated with stillbirths in a series of single-adjusted and mutually adjusted logistic regression models. Upon identification of the risk factors with the strongest associations, we constructed a risk score on the basis of the magnitude of the ß coefficient to examine the cumulative effects of risk factors on stillbirths. To assess whether the associations between risk scores and stillbirths were moderated by protective factors, we added an interaction term between the identified protective factor and risk scores to the regression model. We also conducted two sets of subgroup analyses for previous history of pregnancy and maternal age at pregnancy and four sets of supplementary analyses to test the robustness of the results. Findings: Among the 795,642 women identified for analysis with at least one pregnancy within the five years before the survey, the most recent pregnancy of 8968 (1.13%) ended as stillbirths. Using a mutually adjusted regression model, we found that the top factors showing the strongest associations with stillbirths were short maternal height (odds ratio [OR]: 1.99, 95% confidence interval [CI]: 1.48-2.67, P < 0.001), interpregnancy interval less than six months (OR: 1.84, 95% CI: 1.42-2.38, P < 0.001), previous stillbirth history (OR: 1.55, 95% CI: 1.07-2.26, P < 0.020), low maternal education (OR: 1.50, 95% CI: 1.01-2.24, P = 0.045), and lowest household wealth (OR: 1.32, 95% CI: 1.08-1.61, P = 0.008). A female household head was a protective factor with an OR of 0.71 (95% CI: 0.55-0.90, P = 0.005). Single-adjusted models, subgroup analyses, and sensitivity analyses showed generally consistent results. We also found that the odds of stillbirths increased with a larger risk score with a P trend <0.001. Compared with women without any risk factors, women with a risk score of 5 or more were 4.11 (95% CI: 2.83-5.97, P < 0.001) times more likely to have their pregnancies ending up as stillbirths. However, these associations were weakened if the head of household was female. Interpretation: Our study suggested that short maternal height, low socioeconomic status, previous stillbirth history, low maternal education, and very short interpregnancy interval had the strongest associations with stillbirths. The construction of risk scores using easily observable risk factors could be an effective way to identify high-risk pregnancies in resource-poor settings.

Enhancing Nutrition and Antenatal Infection Treatment (ENAT) study: protocol of a pragmatic clinical effectiveness study to improve birth outcomes in Ethiopia.

INTRODUCTION: The WHO Nutrition Target aims to reduce the global prevalence of low birth weight by 30% by the year 2025. The Enhancing Nutrition and Antenatal Infection Treatment (ENAT) study will test the impact of packages of pregnancy interventions to enhance maternal nutrition and infection management on birth outcomes in rural Ethiopia. METHODS AND ANALYSIS: ENAT is a pragmatic, open-label, 2×2 factorial, randomised clinical effectiveness study implemented in 12 rural health centres in Amhara, Ethiopia. Eligible pregnant women presenting at antenatal care (ANC) visits at <24 weeks gestation are enrolled (n=2400). ANC quality is strengthened across all centres. Health centres are randomised to receive an enhanced nutrition package (ENP) or standard nutrition care, and within each health centre, individual women are randomised to receive an enhanced infection management package (EIMP) or standard infection care. At ENP centres, women receive a regular supply of adequately iodised salt and iron-folate (IFA), enhanced nutrition counselling and those with mid-upper arm circumference of <23 cm receive a micronutrient fortified balanced energy protein supplement (corn soya blend) until delivery. In standard nutrition centres, women receive routine counselling and IFA. EIMP women have additional screening/treatment for urinary and sexual/reproductive tract infections and intensive deworming. Non-EIMP women are managed syndromically per Ministry of Health Guidelines. Participants are followed until 1-month post partum, and a subset until 6 months. The primary study outcomes are newborn weight and length measured at <72 hours of age. Secondary outcomes include preterm birth, low birth weight and stillbirth rates; newborn head circumference; infant weight and length for age z-scores at birth; maternal anaemia; and weight gain during pregnancy. ETHICS AND DISSEMINATION: ENAT is approved by the Institutional Review Boards of Addis Continental Institute of Public Health (001-A1-2019) and Mass General Brigham (2018P002479). Results will be disseminated to local and international stakeholders. REGISTRATION NUMBER: ISRCTN15116516.

Assessing the prevalence of young children living in households prepared for COVID-19 in 56 low- and middle-income countries.

BACKGROUND: The COVID-19 pandemic and governments' attempts to contain it are negatively affecting young children's health and development in ways we are only beginning to understand and measure. Responses to the pandemic are driven largely by confining children and families to their homes. This study aims to assess the levels of and associated socioeconomic disparities in household preparedness for protecting young children under the age of five from being exposed to communicable diseases, such as COVID-19, in low- and middle-income countries (LMICs). METHODS: Using data from nationally representative household surveys in 56 LMICs since 2016, we estimated the percentages of young children under the age of five living in households prepared for communicable diseases (e.g., COVID-19) and associated residential and wealth disparities at the country- and aggregate-level. Preparedness was defined on the basis of space for quarantine, adequacy of toilet facilities and hand hygiene, mass media exposure at least once a week, and phone ownership. Disparities within countries were measured as the absolute gap in two domains-household wealth and residential area - and compared across regions and country income groups. RESULTS: The final data set included 766,313 children under age five. On average, 19.4% of young children in the 56 countries lived in households prepared for COVID-19, ranging from 0.6% in Ethiopia in 2016 to 70.9% in Tunisia in 2018. In close to 90% of countries (50), fewer than 50% of young children lived in prepared households. Young children in rural areas or in the poorest households were less likely to live in prepared households than their counterparts. CONCLUSIONS: A large portion of young children under the age of five in LMICs were living in households that did not meet all preparedness guidelines for preventing COVID-19 and caring for patients at home. This study highlights the need to ensure all families in LMICs have the means to prevent the spread of the pandemic or other communicable illnesses to young children during pandemics.

Impact of out-of-pocket expenses for surgical care on households in rural Haiti: a mixed-methods study.

OBJECTIVES: This study aimed to report household catastrophic spending on surgery and the experiences of patients and families seeking surgical care in rural Haiti. DESIGN: The study used an explanatory, sequential mixed-methods approach. We collected both quantitative and qualitative data from the participants through interviews. SETTING: A rural tertiary hospital (St. Boniface Hospital) in southern Haiti. PARTICIPANTS: There were 200 adult Haitian surgical patients who entered the study. Of these, 41 were excluded due to missing variables or health expenditure outliers. The final sample included 159 participants. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcomes were (1) direct and indirect payments for surgical care; (2) the rate of catastrophic health expenditure (CHE) (as defined by the Sustainable Development Goals (10% of total household expenditure) and WHO (10%, 20%, 30% and 40% of household capacity to pay)) due to surgical care; and (3) common themes across the lived experiences of households of surgical patients seeking care. RESULTS: The median household expenditure on surgery-related expenses was US$385.6, slightly more than half of per capita gross domestic product in Haiti (US$729.3). Up to 86% of households experienced CHE, as defined by the Sustainable Development Goals, due to receiving surgical care. Patients commonly paid for surgical costs through loans and donations (69.8%). The qualitative analysis revealed prominent themes related to barriers to care including the burden of initiating care-seeking, care-seeking journeys and social suffering. CONCLUSIONS: CHE is common for Haitian surgical patients, and the associated care-seeking experiences are often arduous. These findings suggest that low, flat fees in non-profit hospital settings may not be sufficient to mitigate the costs of surgical care or the resulting challenges that patients experience.

RAB26 contributes to the progression of non-small cell lung cancer after being transcriptionally activated by SMAD3.

Non-small cell lung cancer (NSCLC) accounts for 85% of all cases of lung cancer, which constitutes the leading cause of cancer mortality. RAB26, a member of Rab GTPase superfamily, has been suggested to play a role in the tumorigenesis of NSCLC. The present work aimed to explore whether and how RAB26 contributed to the progression of NSCLC. NSCLC cell line A549 was transfection with short hairpin RNA (shRNA) or overexpression (Ov) vector to knockdown RAB26 or overexpress SMAD3, respectively. Then the malignant processes of A549 cells including proliferation, migration, invasion and apoptosis were evaluated by CCK-8, colony formation, wound-healing, transwell and TUNEL assays, respectively. Expression of proteins involved in these processes was measured by western blot. A549 xenograft mice model was established to confirm the effect of RAB26 silence on NSCLC progression in vivo. The relationship between RAB26 and SMAD3 was analyzed by bioinformatics and then verified by dual-luciferase reporter and chromatin immunoprecipitation (ChIP) assays. We found that silence of RAB26 inhibited the proliferation, migration and invasion but promoted apoptosis of A549 cells. In vivo studies revealed that the tumor growth of A549 xenograft was markedly suppressed upon RAB26 silence. Moreover, it was confirmed that SMAD3 bound to the promoter of RAB26 and enhance its expression. Finally, we observed that overexpression of SMAD3 significantly blocked the inhibitory effect of RAB26 silence on NSCLC progression. Collectively, RAB26 may contribute to the progression of NSCLC after being transcriptionally activated by SMAD3.

Assessing the long-term effects of Basic Medical Insurance on catastrophic health spending in China.

Many developing countries have implemented social health insurance programmes to protect their citizens against the financial risks of seeking healthcare. While many studies have explored how individual insurance enrolments affect catastrophic health spending (CHS) in the short term, there is a lack of evidence on the long-term macro-level effects of social health insurance on CHS in low- and middle-income countries. This study examines the long-term effects of Basic Medical Insurance (BMI) on individual CHS in China, a middle-income country that has witnessed one of the highest worldwide increases in CHS rates despite its remarkable achievement of universal health insurance coverage. Specifically, we used existing longitudinal data from 1989 to 2015, therein assessing BMI policy effects by constructing two macro-level indicators, including the year of BMI presence at the prefectural level and number of years relative to BMI introduction. We employed a three-level difference-in-differences approach for the estimation. There were two main findings. First, BMI policy did not significantly reduce the probability of incurring CHS for BMI enrollees over time. Years after BMI was introduced, the policy even predicted a significant increase in the probability of incurring CHS for individuals who shifted their enrolments from traditional insurance to BMI. Second, BMI policy had spillover effects on the increase in the probability of incurring CHS for non-BMI individuals a few years after its inception. We believe there are three possible explanations for these findings: (1) shrinking BMI service coverage compared to pre-existing government-funded insurance schemes, (2) a profit-driven hospital reform that induces the overuse of expensive medicines and diagnostic tests and (3) the absence of strategic purchasing among local BMI agencies. We also discuss how relevant policy interventions may alleviate insurance-driven financial risks.

Economic evaluation and costs of telepsychiatry programmes: A systematic review.

OBJECTIVE: Telepsychiatry involves use of telecommunications technology to deliver psychiatric care and offers promise to reduce costs and increase access to mental health services. This systematic review examined cost reporting of telepsychiatry programmes for mental healthcare. METHODS: We systematically searched electronic databases for studies reporting costs, including economic evaluations such as cost-effectiveness analyses, or costs of developing telepsychiatry programmes for clinical care of mental disorders. Included studies enrolled participants with mental disorders and involved telepsychiatry for depression, anxiety disorders, serious mental illnesses including schizophrenia spectrum disorders and bipolar disorder, post-traumatic stress disorder, dementia or epilepsy. RESULTS: Twenty-six unique studies met inclusion criteria (17,967 participants), with most targeting depression (n = 7; 27%), general mental disorders and screening (n = 7; 27%), child mental health (n = 4; 15%) and geriatric mental health (n = 4; 15%). Nearly all studies (n = 25; 96%) compared telepsychiatry programme costs with either standard in-person consultation or usual care, with 15 (60%) reporting that telepsychiatry programmes were less expensive, and 8 (32%) showing telepsychiatry programmes were more expensive. Three studies reported cost-effectiveness analyses, favouring telepsychiatry programmes, but at highly elevated cost-effectiveness thresholds. Few studies reported costs of developing or delivering telepsychiatry programmes. CONCLUSION: Costs of telepsychiatry programmes varied widely, with substantial heterogeneity in how costs were defined and reported. Some programmes cost less than in-person services while others cost more. Therefore, rigorous cost-effectiveness studies following established standards in economic evaluation are needed to inform implementation and sustainability of these programmes in health systems.
