The African region remains the world's most affected region in the HIV epidemic. A related consequence of HIV/AIDS in sub-Saharan Africa (SSA), including in Uganda, is the high prevalence of children and adolescents who have lost one or both parents to this virus or who have been perinatally infected. Guided by the Practical, Robust Implementation and Sustainability (PRISM) framework, this paper describes the strategies by which we have engaged community and government partners in research using three NIH-funded randomized clinical trials testing an evidence-based combination intervention aimed at improving health and mental health outcomes among children and adolescents impacted by HIV/AIDS in Uganda. We specifically lay out four strategies that have been used to facilitate stakeholder engagement, namely consultative meetings, stakeholder accountability meetings, training of key players (task-shifting), and policymaker engagement. We emphasize that community collaborations and partnerships are especially critical when implementing combination interventions that require a high level of communication and coordination among multiple implementation partners. We underline that building and sustaining long-term relationships and communication with the stakeholders can allow the researchers to successfully design rigorous studies that are responsive to local needs and can make a difference especially in low-resource settings. Finally, we highlight that the process of engagement and collaboration can be guided by conceptual frameworks.

Electronic cigarettes (e-cigarettes) are commonly used devices by adolescents and young adults. Since their introduction, the popularity of e-cigarettes has increased significantly with close to twenty percent of United States high school students reporting current use in 2020. As the number of e-cigarette users has increased, so have reports of vaping related health complications. Overall, respiratory tract infections remain one of the top ten leading causes of death in the US for every age group. Specific to the pediatric population, lower respiratory tract infections are the leading cause for hospitalization. This review highlights the current evidence behind e-cigarette exposure and its association with impaired innate immune function and the risk of lower respiratory tract infections. To date, various preclinical models have evaluated the direct effects of e-cigarette exposure on the innate immune system. More specifically, e-cigarette exposure impairs certain cell types of the innate immune system including the airway epithelium, lung macrophage and neutrophils. Identified effects of e-cigarette exposure common to the lung's innate immunity include abnormal mucus composition, reduced epithelial barrier function, impaired phagocytosis and elevated systemic markers of inflammation. These identified impairments in the lung's innate immunity have been shown to increase adhesion of certain bacteria and fungi as well as to increase virulence of common respiratory pathogens such as influenza virus, Staphylococcus aureus or Streptococcus pneumoniae. Information summarized in this review will provide guidance to healthcare providers, policy advocates and researchers for making informed decisions regarding the associated respiratory health risks of e-cigarette use in pediatric and young adults.
