Challenges and Opportunities in China’s Health Aid to Africa: Findings from Qualitative Interviews in Tanzania and Malawi
Background
China has played an increasing role in development aid across Africa. Most recently, China has increased its external investments through the Belt and Road Initiative, China’s signature infrastructure and trade drive to link China to Asia and Africa. This is likely to result in continuing growth of China’s investment in health in sub Saharan Africa. While conflicting opinions have been raised regarding the motivation and value of these investments, few data have been solicited from those directly involved in China-Africa health aid. We conducted a qualitative study to collect information on perceptions and opinions regarding Chinese-supported health related activities in Africa through in-depth interviews among local African and Chinese participants in Malawi and Tanzania.
Results
Our findings reveal shared experiences and views related to challenges in communication; cultural perspectives and historical context; divergence between political and business agendas; organization of aid implementation; management and leadership; and sustainability. Participants were broadly supportive and highly valued Chinese health aid. However, they also shared common insights that relate to challenging coordination between China and recipient countries; impediments to communication between health teams; and limited understanding of priorities and expectations. Further, they share perspectives about the need for shaping the assistance based on needs assessments as well as the importance of rigorous reporting, and monitoring and evaluation systems.
Summary
Our findings suggest that China faces similar challenges to those experienced by other longstanding development aid and global health donors. As it continues to expand cooperation across Africa and other regions, it will be important for China to consider the issues identified through our study to help inform collaborative and effective global health assistance programs. The insights garnered from this research are not only relevant to China’s engagement in Africa but for other global health assistance donors as well

Genome sequences reveal global dispersal routes and suggest convergent genetic adaptations in seahorse evolution
Seahorses have a circum-global distribution in tropical to temperate coastal waters. Yet, seahorses show many adaptations for a sedentary, cryptic lifestyle: they require specific habitats, such as seagrass, kelp or coral reefs, lack pelvic and caudal fins, and give birth to directly developed offspring without pronounced pelagic larval stage, rendering long-range dispersal by conventional means inefficient. Here we investigate seahorses’ worldwide dispersal and biogeographic patterns based on a de novo genome assembly of Hippocampus erectus as well as 358 re-sequenced genomes from 21 species. Seahorses evolved in the late Oligocene and subsequent circum-global colonization routes are identified and linked to changing dynamics in ocean currents and paleo-temporal seaway openings. Furthermore, the genetic basis of the recurring “bony spines” adaptive phenotype is linked to independent substitutions in a key developmental gene. Analyses thus suggest that rafting via ocean currents compensates for poor dispersal and rapid adaptation facilitates colonizing new habitats.Fil: Chunyan, Li.

Capability of IMERG V6 Early, Late, and Final Precipitation Products for Monitoring Extreme Precipitation Events
The monitoring of extreme precipitation events is an important task in environmental research, but the ability of the Integrated Multi-satellitE Retrievals for Global Precipitation Measurement (IMERG) precipitation products to monitor extreme precipitation events remains poorly understood. In this study, three precipitation products for IMERG version 6, early-, late-, and final-run products (IMERG-E, IMERG-L, and IMERG-F, respectively), were used to capture extreme precipitation, and their applicability to monitor extreme precipitation events over Hubei province in China was evaluated. We found that the accuracy of the three IMERG precipitation products is inconsistent in areas of complex and less complex topography. Compared with gauge-based precipitation data, the results reveal the following: (1) All products can accurately capture the spatiotemporal variation patterns in precipitation during extreme precipitation events. (2) The ability of IMERG-F was good in areas of complex topography, followed by IMERG-E and IMERG-L. In areas of less complex topography, IMERG-E and IMERG-L produced outcomes that were consistent with those of IMERG-F. (3) The three IMERG precipitation products can capture the actual hourly precipitation tendencies of extreme precipitation events. (4) In areas of complex topography, the rainfall intensity estimation ability of IMERG-F is better than those of IMERG-E and IMERG-L
A novel long-lasting antifouling membrane modified with bifunctional capsaicin-mimic moieties via in situ polymerization for efficient water purification
Capsaicin-mimic materials are promising candidates for antifouling membrane fabrication. However, the membrane fabrication is usually complicated and the long-term operation of the resulting membrane is unstable. In this work, we developed an "in situ polymerization-blending" technique to prepare capsaicin-containing polysulfone membranes. This facile one-pot synthesis applied a capsaicin derivative containing two carbon-carbon double bonds (N-(2-hydroxyl-3-methyl acrylamide-4,6-dimethyl benzyl) acrylamide, (HMDA)). The presence of carbon-carbon double bonds enabled the self-polymerization of HMDA, leading to stable anchoring of the capsaicin derivative on the membrane. The composite membrane exhibited higher pure water permeability (up to 3124.7 L m h MPa, over two times higher than that of the pure membrane) without compromising the humic acid rejection efficiency. In addition, the composite membranes also exhibited significantly improved resistance to organic fouling (humic acid) and bacteria (E. coli)/algae (Prorocentrum donghaiense) growth. The presence of unreacted carbon-carbon double bonds on HMDA also allowed gradual polymerization when exposed chronically to air or water environments, which ensured good operational stability over 2 months. The novel membrane fabrication technique in this work offers significant opportunities to exploit the unique properties of capsaicin derivatives in the fabrication of various separation membranes
Delayed Treatment for People Living with HIV in China, 2004–2016: An Analysis of An Observational Cohort
Early universal access to antiretroviral treatment (ART) is critical in the control of the HIV epidemic. However, prompt initiation of ART remains problematic in China. This study analyzed the late testing and lag time between HIV diagnosis and initiation of ART from 2004 to 2016 and identified the risk factors for delayed initiation of ART. Data from 16,957 people living with HIV were abstracted from a hospital electronic health record database and a case report database for AIDS prevention and control in Yunnan province. Reasons for delayed initiation of ART were categorized into late testing, defined as CD4 count of < 350 cells/μL at baseline HIV diagnosis, and delayed access, defined as a lag time of > 1 month between the diagnosis and initiation of ART. Binary logistic regression models were used to identify risk factors for late testing and delayed access. The CD4 counts at diagnosis increased from 201 ± 147 cells/μL (mean ± SD) in 2004 to 324 ± 238 cells/μL in 2016 (p = 0.024). The CD4 count was higher for persons < 45 years, unmarried, and men who have sex with men (MSM) (356, 357, and 409 cells/μL, respectively) compared to their peers in 2016 (p < 0.05). The lag time from diagnosis to initiation of ART was significantly reduced from 59.2 months in 2004 to 0.9 months in 2016 (p < 0.05). The shorter lag time over the years was consistent when analysis was stratified by sex, age, marital status, and transmission routes, even though the lag time for people using drugs was longest in 2016 (> 2 months versus 0.82 and 0.72 month of heterosexuals and MSM, respectively). Compared to their peers, married persons (AOR = 0.63, 95%CI: 0.57, 0.69) were less likely to have delayed access to ART, and drugs-using patients (AOR = 3.58, 95%CI: 2.95,4.33) were more likely to have delayed access to ART. Late testing rather than delayed access to ART after a diagnosis remains problematic in China, although improvements have been seen for both parameters from 2004 to 2016. Our data highlight the importance of continued efforts to promote early diagnosis of HIV to prevent transmission, morbidity, and early mortality in HIV infection

China’s health assistance to Africa: opportunism or altruism?
China has made substantial health commitments to Africa in the past several decades. However, while much has been written regarding China-Africa aid overall, relatively little attention has been given to China’s health aid. To better understand these investments, we provide an overview of the current framework and characteristics of China’s health aid to Africa. China’s health assistance has been perceived by some as opportunistic, largely as a demonstration of China’s engagement in “soft power” and an attempt to enhance its access to natural resources and political favors by African countries. Others have attributed altruistic intent, aiming to support the advancement of the health of populations in the African continent with a “no strings attached” approach. Our overview demonstrated that despite the magnitude of China’s health assistance, many questions remain regarding the scope of this aid, its effectiveness and the governance mechanisms that guide the conceptualization and implementation of such efforts. We also identified the need for a systematic and rigorous evaluation of the various elements of China’s health assistance to African countries in order to gain a deeper understanding of how priorities and allocations for health aid are determined, how such aid fits within the specific African country’s health strategies and to assess the effectiveness of such aid. Insights garnered through such an assessment could help determine future priorities for investment as well as inform efforts to optimize the value of China's aid for the populations of the recipient countries
Migration experiences and reported commercial and non-commercial sexual behaviors among newly diagnosed HIV infections in China: a cross-sectional study
Abstract Background Migration is known to influence human health. China has a high migration rate and a significant number of people who are HIV-positive, but little is known about how these factors intersect in sexual risk behaviors. Objective This study aimed to explore sexual risk behaviors between migrants and non-migrants among newly diagnosed HIV infections, and assess the changes of sexual risk behaviors with length of stay in the current city of migrants. Methods A cross-sectional questionnaire was conducted among people newly diagnosed with HIV from July 2018 to December 2020 who lived in Zhejiang Province. In the study, sexual risk behaviors included having multiple sexual partners and unprotected sexual behaviors (in commercial sexual behaviors, non-commercial sexual behaviors, heterosexual behaviors, and homosexual behaviors). Binary logistic regression models were employed to explore the influencing factors of sexual risk behaviors, measured by multiple sexual partners and unprotected sexual partners. Results A total of 836 people newly diagnosed with HIV/AIDS were incorporated in the study and 65.31% (546) were migrants. The percentages of non-commercial sexual behaviors among migrants were statistically higher than those of non-migrants. Commercial heterosexual behavior was higher among non-migrants compared with migrants. The proportion of study participants having unprotected sexual behaviors and multiple sexual partners with commercial/non-commercial partners was both higher among migrants compared with non-migrants. Among migrants, the likelihood of sexual risk behaviors in both commercial and non-commercial sex increased in the first 3 years and reduced after 10 years. Compared with non-migrants, migrants were statistically associated with multiple sexual partners [P = .007, odds ratio (OR) = 1.942]. However, migrants did not exhibit a significant difference in unprotected sexual behaviors compared with non-migrants. In addition, migrants aged between 18 and 45 years who relocated to the current city in the past 2–3 years tended to have multiple sexual partners (P < .05). Conclusions People newly diagnosed with HIV engaged in different sexual risk behaviors among migrants and non-migrants and more attention should be paid to migrants. For non-migrants, it is urgent to promote the prevention of commercial sexual behaviors. For migrants, prevention of non-commercial sexual behaviors and universal access to health care especially for new arrivals who migrated to the current city for 2–3 years are needed. Moreover, sexual health education and early HIV diagnosis are necessary for the entire population
