    Abstract Background: Sexually transmitted diseases (STDs) are a serious issue worldwide. With the popularity of the internet, online health information-seeking behavior (OHISB) has been widely adopted to improve health and prevent disease.
    Objective: This study aimed to investigate the short-term and long-term effects of different types of OHISBs on STDs, including syphilis, gonorrhea, and AIDS due to HIV, based on the Baidu index.
    Methods: Multisource big data were collected, including case numbers of STDs, search queries based on the Baidu index, provincial total population, male-female ratio, the proportion of the population older than 65 years, gross regional domestic product (GRDP), and health institution number data in 2011-2018 in mainland China. We categorized OHISBs into 4 types: concept, symptoms, treatment, and prevention. Before and after controlling for socioeconomic and medical conditions, we applied multiple linear regression to analyze associations between the Baidu search index (BSI) and Baidu search rate (BSR) and STD case numbers. In addition, we compared the effects of 4 types of OHISBs and performed time lag cross-correlation analyses to investigate the long-term effect of OHISB.
    Results: The distributions of both STD case numbers and OHISBs presented variability. For case number, syphilis, and gonorrhea, cases were mainly distributed in southeastern and northwestern areas of China, while HIV/AIDS cases were mostly distributed in southwestern areas. For the search query, the eastern region had the highest BSI and BSR, while the western region had the lowest ones. For 4 types of OHISB for 3 diseases, the BSI was positively related to the case number, while the BSR was significantly negatively related to the case number (P<.05). Different categories of OHISB have different effects on STD case numbers. Searches for prevention tended to have a larger impact, while searches for treatment tended to have a smaller impact. Besides, due to the time lag effect, those impacts would increase over time.
    Conclusions: Our study validated the significant associations between 4 types of OHISBs and STD case numbers, and the impact of OHISBs on STDs became stronger over time. It may provide insights into how to use internet big data to better achieve disease surveillance and prevention goals.

    Abstract Background: This study views sustainability after the exit of development assistance for health (DAH) as a shared responsibility between donors and recipients and sees transitioning DAH-supported interventions into domestic health policy as a pathway to this sustainability. It aims to uncover and understand the reemergent aspects of the donor-recipient dynamic in DAH and how they contribute to formulating domestic health policy and post-DAH sustainability.
    Methods: We conducted a case study on two DAH-supported interventions: medical financial assistance in the Basic Health Services Project supported by the World Bank and UK (1998-2007) and civil society engagement in the HIV/AIDS Rolling Continuation Channel supported by the Global Fund (2010-2013) in China. From December 2021 to December 2022, we analyzed 129 documents and interviewed 46 key informants. Our data collection and coding were guided by a conceptual framework based on Walt and Gilson's health policy analysis model and the World Health Organization's health system building blocks. We used process tracing for analysis.
    Results: According to the collected data, our case study identified three reemergent, interrelated aspects of donor-recipient dynamics: different preferences and compromise, partnership dialogues, and responsiveness to the changing context. In the case of medical financial assistance, the dynamic was characterized by long-term commitment to addressing local needs, on-site mutual learning and understanding, and local expertise cultivation and knowledge generation, enabling proactive responses to the changing context. In contrast, the dynamic in the case of HIV/AIDS civil society engagement marginalized genuine civil society engagement, lacked sufficient dialogue, and exhibited a passive response to the context. These differences led to varying outcomes in transnational policy diffusion and sustainability of DAH-supported interventions between the cases.
    Conclusions: Given the similarities in potential alternative factors observed in the two cases, we emphasize the significance of the donor-recipient dynamic in transnational policy diffusion through DAH. The study implies that achieving post-DAH sustainability requires a balance between donor priorities and recipient ownership to address local needs, partnership dialogues for mutual understanding and learning, and collaborative international-domestic expert partnerships to identify and respond to contextual enablers and barriers.

    Abstract Background: Risky sexual behavior (RSB), the most direct risk factor for sexually transmitted infections (STIs), is common among college students. Thus, identifying relevant risk factors and predicting RSB are important to intervene and prevent RSB among college students.
    Objective: We aim to establish a predictive model for RSB among college students to facilitate timely intervention and the prevention of RSB to help limit STI contraction.
    Methods: We included a total of 8794 heterosexual Chinese students who self-reported engaging in sexual intercourse from November 2019 to February 2020. We identified RSB among those students and attributed it to 4 dimensions: whether contraception was used, whether the contraceptive method was safe, whether students engaged in casual sex or sex with multiple partners, and integrated RSB (which combined the first 3 dimensions). Overall, 126 predictors were included in this study, including demographic characteristics, daily habits, physical and mental health, relationship status, sexual knowledge, sexual education, sexual attitude, and previous sexual experience. For each type of RSB, we compared 8 machine learning (ML) models: multiple logistic regression (MLR), naive Bayes (BYS), linear discriminant analysis (LDA), random forest (RF), gradient boosting machine (GBM), extreme gradient boosting (XGBoost), deep learning (DL), and the ensemble model. The optimal model for both RSB prediction and risk factor identification was selected based on a set of validation indicators. An MLR model was applied to investigate the association between RSB and identified risk factors through ML methods.
    Results: In total, 5328 (60.59%) students were found to have previously engaged in RSB. Among them, 3682 (41.87%) did not use contraception every time they had sexual intercourse, 3602 (40.96%) had previously used an ineffective or unsafe contraceptive method, and 1157 (13.16%) had engaged in casual sex or sex with multiple partners. XGBoost achieved the optimal predictive performance on all 4 types of RSB, with the area under the receiver operator characteristic curve (AUROC) reaching 0.78, 0.72, 0.94, and 0.80 for contraceptive use, safe contraceptive method use, engagement in casual sex or with multiple partners, and integrated RSB, respectively. By ensuring the stability of various validation indicators, the 12 most predictive variables were then selected using XGBoost, including the participants' relationship status, sexual knowledge, sexual attitude, and previous sexual experience. Through MLR, RSB was found to be significantly associated with less sexual knowledge, more liberal sexual attitudes, single relationship status, and increased sexual experience.
    Conclusions: RSB is prevalent among college students. The XGBoost model is an effective approach to predict RSB and identify corresponding risk factors. This study presented an opportunity to promote sexual and reproductive health through ML models, which can help targeted interventions aimed at different subgroups and the precise surveillance and prevention of RSB among college students through risk probability prediction.

    Abstract Background: Women and children bear a substantial burden of morbidity and mortality due to armed conflict. Life-saving maternal and child health (MCH) services are low-quality in most conflict-affected regions. Previous studies on armed conflict and MCH services have been mostly cross-sectional, and a causal relationship between armed conflict and MCH services utilisation cannot be inferred.
    Methods: First, we constructed a utility equation for maternal health-seeking behaviour. Next, we extracted MCH data from the Multiple Indicator Cluster Survey led by the UNICEF. Armed conflict data were obtained from the Uppsala Conflict Data Programme; 55 683 women aged 15-49 from Chad, the Central African Republic, the Democratic Republic of Congo (DRC) and the Republic of Iraq were selected as participants. We fitted a difference-in-differences (DID) model, taking before or after the conflict started as an exposure variable to estimate the effects of armed conflict on maternal health-seeking behaviours.
    Results: According to the results of the DID model, in the regional sample, armed conflict had a positive effect on tetanus vaccination (β=0.055, 95% CI 0.004 to 0.106, p<0.05), and had a negative effect on antenatal care at least eight visits (ANC8+) (β=-0.046, 95% CI -0.078 to -0.015, p<0.01). And, the effects of armed conflict on ANC, ANC4+, institutional delivery and early initiation of breast feeding (EIB) were not statistically significant. As for the country sample, we found that armed conflict had a negative effect on EIB (β=-0.085, 95% CI -0.184 to 0.015, p<0.1) in Chad. In Iraq, armed conflict had positive impacts on ANC (β=0.038, 95% CI -0.001 to 0.078, p<0.1) and tetanus vaccination (β=0.059, 95% CI 0.012 to 0.107, p<0.05), whereas it had a negative effect on ANC8+ (β=-0.039, 95% CI -0.080 to 0.002, p<0.1). No statistically significant associations were discovered in DRC based on the DID model.
    Conclusions: There might be a mixed effect of armed conflict on maternal health-seeking behaviours. In the absence of humanitarian assistance, armed conflict reduces certain maternal health-seeking behaviours, such as ANC8+. When practical humanitarian health assistance is provided, the damage can be alleviated, and even the prevalence of maternal health-seeking behaviours can be improved, such as tetanus vaccination. Providing humanitarian assistance to conflict-affected regions improved the accessibility of MCH services for women living in those areas. However, the goals of saving lives and alleviating suffering still need to be achieved. In conflict-affected regions, humanitarian assistance on ANC, institutional delivery and breast feeding need strengthening.

    Abstract The development of efficient photocathodes is of critical importance for the constructions of promising tandem photo-electrochemical cells. Most known dye-sensitized photocathodes are prepared with the conventional carboxylic or phosphonic acid anchors and require the presence of other terminal linking groups to connect catalysts; they suffer from high synthetic difficulty and low adsorption stability in aqueous media. Here, a compact bilayer photocathode has been prepared by using a pyrene-based photosensitizer with multiple terminal pyridine moieties as both the anchoring and linking groups to connect a Co hydrogen-evolution catalyst to the NiO substrate. The catalyst and dye molecule are assembled in a layer-by-layer manner on NiO through the metal-pyridine coordination. This photocathode exhibits good dye adsorption stability in aqueous media.

    Abstract Objective: Malnutrition in the Democratic Republic of the Congo (DRC) has declined over the past 2 decades. However, malnutrition inequality persists. Evaluating trends of socioeconomic disparities in malnutrition among children under 5 y of age in the DRC can help target meaningful interventions.
    Method: Data from the Multiple Indicator Cluster Survey (2001, 2010, 2018) assessed the prevalence of underweight, stunting, and wasting among children under 5. The Slope Index of Inequality (SII) and the Relative Index of Inequality (RII) measured socioeconomic inequalities. We evaluated trends in the entire national sample and stratified subsamples based on place of residence and wealth index quintiles. The final sample included 42 976 children.
    Results: The national prevalence of underweight and wasting decreased from 31% to 26% and 13% to 6% in rural and urban areas. However, trends in stunting prevalence varied between the two areas. Nutritional disparity widened between low- and high-income families (stunting RIIs: 0.61 in 2001, 0.37 in 2018; stunting SIIs: -0.20 in 2001, -0.40 in 2018; underweight RIIs: 0.53 in 2001, 0.35 in 2018; underweight SIIs: -0.21 in 2001, -0.28 in 2018). Urban areas experienced greater inequality than rural areas (stunting in urban RIIs: 0.41 in 2001, 0.33 in 2010, 0.25 in 2018).
    Conclusion: Despite progress in reducing malnutrition, persistent socioeconomic disparities, particularly in urban areas, remain a serious public health concern in the DRC. Addressing the root causes of malnutrition and ensuring socioeconomically equitable access to nutrition is critical to promote the full potential of children.

    Abstract Background: Ulcer colitis (UC) is a chronic, nonspecific, and noninfectious inflammatory bowel disease. Recently, Toll-like receptors (TLRs) have been found to be closely associated with clinical inflammatory diseases. Achieving complete remission in patients with intermittent periods of activity followed by dormancy is challenging. Moreover, no study has explored the mechanism by which Kuicolong-yu enema decoction retains traditional Chinese medicine enemas to attenuate the inflammatory response in UC.
    Aim: To explore the mechanism by which Kuicolong-yu enema decoction retains traditional Chinese medicine enemas to attenuate the inflammatory response in UC.
    Methods: This prospective clinical study included patients who met the exclusion criteria in 2020 and 2021. The patients with UC were divided into two groups (control and experimental). The peripheral blood of the experimental and control groups were collected under aseptic conditions. The expression of TLR4 protein, NF-κB, IL-6, and IL-17 was detected in the peripheral blood of patients in the experimental group and control group before and 1 month after taking the drug. Linear correlation analysis was used to analyze the relationship between the expression level of TLR4 protein and the expression levels of downstream signal NF-κB and inflammatory factors IL-6 and IL-17, and
    Results: There were no significant differences in the patient characteristics between the control and experimental groups. The results showed that the expression levels of TLR4 and NF-κB in the experimental group were significantly lower than those in the control group (
    Conclusion: Kuicolong-yu enema decoction retains traditional Chinese medicine enema attenuates the inflammatory response of UC through the TLR4/NF-κB signaling pathway.

    Abstract Background: Preadolescents, who are in a transitional phase of development, may experience higher exposure to heterosexual interactions while facing higher risks regarding misinformation in sexual knowledge and unsafe engagement in sexual activities. There is a deficiency in the availability of qualified educators and age-appropriate teaching materials for sexuality education in China.
    Methods: We implemented an animation-based comprehensive sexuality education package among preadolescents aged 9 to 12 years from eight schools in Anhui, China. The first round of intervention included 1,835 participants, lasting 2 months from September to November 2020. A total of 374 participants, accounting for 52% of the intervention group, received a second round of intervention in September 2021. Participants completed immediate follow-up assessment and 1-year follow-up assessment to assess changes in their sexual knowledge, attitudes, and other outcomes. Propensity score matching and difference-in-difference analysis were performed to determine the short- and long-term impacts.
    Results: Significant improvements were observed for both sexual knowledge and sexual attitudes in the immediate follow-up. There was no significant effect on pornography-seeking behavior or awareness of experiencing sexual abuse. After 1 year, the effect was sustained for sexual knowledge, but slightly declined for sexual attitudes. The second intervention significantly improved sexual knowledge; however, no significant change in sexual attitudes, pornography-seeking behavior, or awareness of experiencing sexual abuse was observed.
    Conclusions: Our comprehensive sexuality education package was effective in improving sexual knowledge both immediately and 1 year after the intervention. Repeated intervention can be an effective strategy for promoting preadolescent health development regarding comprehensive sexuality education.
