Item Open Access Investigating Mosquitoes’ Behavior for Malaria Prevention in Webuye, Western Kenya(2019) Liao, HuipengInsecticide-treated bed nets (ITNs) are widely used in Kenya to prevent the mosquitoes, which can transmit malaria, from biting people at night. However, there is a concern that mosquitoes become resistant to the ITN environment by changing their feeding behavior. The research goal was to observe the current feeding behavior of female Anopheles in Webuye, Western Kenya. Prokopack aspirators, CDC light traps, and sticky barrier screens were used for mosquito collection during May – July 2018. 662 collected female Anopheles, most of which were Anopheles gambiae sensu lato, were included. Descriptive and statistical analyses were applied, and the results show that the feeding proportion was 79.3% in mornings and 13.7% at nights, which was not significantly affected by the frequency of bed net use. 35.9% and 4.3% of the female Anopheles were human and Plasmodium (P.) Falciparum gDNA positive, respectively. Most of the P.falciparum positives were also fed and human gDNA positive, meaning that most of the infected or infectious mosquitoes had human blood meals and may have already attended malaria transmission. The study failed to observe outdoor feeding behavior by sticky barrier screens, and behavioral adaptation may not be responsible for most of the persistence of transmission. The study implicates a full investigation of ITN condition, more research on chemical resistance, and further surveillance of mosquito biting time.
Item Open Access Prevention of childhood unintentional injuries in low- and middle-income countries: A systematic review.(PloS one, 2020-01) Tupetz, Anna; Friedman, Kaitlyn; Zhao, Duan; Liao, Huipeng; Isenburg, Megan Von; Keating, Elizabeth M; Vissoci, Joao Ricardo Nickenig; Staton, Catherine A; Staton, Catherine AInjuries are a leading cause of death and disability among children. Numerous injury prevention strategies have been successful in high-income countries, but the majority of unintentional injuries happen to children living in low- and middle-income countries (LMICs). This project aims to delineate the childhood injury prevention initiatives in LMICs. For inclusion, peer-reviewed articles needed to address unintentional injury, include children <18, assess a prevention-related intervention, contain a control group, and be published after 1988. Two pairs of reviewers evaluated articles independently to determine study eligibility. 74 articles were included. 30 studies addressed road traffic injuries, 11 drowning, 8 burns, 3 falls, 8 poisonings, and 21 an unspecified injury type. The findings show positive effects on injury outcome measures following educational interventions, the need for longer follow-up periods after the intervention, the need for effectiveness trials for behavior change, and the need for an increase in injury prevention services in LMICs. This is the first systematic review to summarize the prevention initiatives for all types of childhood unintentional injuries in LMICs. Increased attention and funding are required to go beyond educational initiatives with self-reported measures and little follow-up time to robust interventions that will reduce the global burden of unintentional injuries among children.
