Development of an eHealth Intervention Prototype to Prevent Health Risk Behaviors Among Hispanic Adolescents: A User-Centered Formative Study.

Health risk behaviors continue to disproportionately affect Hispanic youth. Despite the existence of successful family and school-based interventions, there is a need for developing and testing individually-based preventive interventions that are easily accessed and widely disseminated. Therefore, this study aimed to develop a prototype (proof of concept) for an individual-level mobile application (app), informed by Hispanic parents and adolescents, to prevent/reduce drug use and sexual risk behaviors among Hispanic youth.

Contribution of malnutrition to infant and child deaths in Sub-Saharan Africa and South Asia.

Introduction: Malnutrition contributes to 45% of all childhood deaths globally, but these modelled estimates lack direct measurements in countries with high malnutrition and under-5 mortality rates. We investigated malnutrition's role in infant and child deaths in the Child Health and Mortality Prevention Surveillance (CHAMPS) network.

Methods: We analysed CHAMPS data from seven sites (Bangladesh, Ethiopia, Kenya, Mali, Mozambique, Sierra Leone and South Africa) collected between 2016 and 2023.

Familias con Orgullo: Pilot Study of a Family Intervention for Latinx Sexual Minority Youth to Prevent Drug Use, Sexual Risk Behavior, and Depressive Symptoms.

Families are key in the healthy development of Latinx sexual minority youth (Latinx SMY), a group that experiences behavioral, mental, and sexual health disparities. Despite this, there are no family-based interventions for Latinx SMY and their families to prevent drug use, sexual risk behaviors, and depressive symptoms. The purpose of this pilot study was to evaluate the preliminary impact (i.

Early return to work is possible after transoral robotic surgery (TORS) in carefully selected patients with oropharyngeal squamous cell carcinoma.

Introduction: The aims of this study were to investigate the rate and time to return to work (RTW) after transoral robotic surgery (TORS) for oropharyngeal squamous cell carcinoma (OPSCC) and to explore the impact of disease or work-related factors leading to variations in RTW outcomes.

Methods: Cross-sectional survey of disease, socioeconomic, work-related and health-related quality of life (HR-QOL). Qualitative analysis of responses for facilitators and barriers to RTW.

Safety, reactogenicity, and immunogenicity of ZR-202-CoV and ZR-202a-CoV recombinant vaccines compared with Comirnaty: A randomized, observer-blind, controlled, phase 1 study.

Objectives: ZR-202-CoV and ZR-202a-CoV are novel recombinant vaccines containing 25 µg of the prototype (Wuhan strain) or B.1.351 strain (Beta variant) SARS-CoV-2 S-protein expressed in CHO cells, respectively, adjuvanted with Al(OH) and CpG-ODN.

Coronavirus awareness, prevention, and household hardship survey data for the CHAMPS HDSS network: Data collected between August and September of 2022 from the Bamako HDSS, Mali.

Data were gathered through a collaborative initiative to investigate impacts of the COVID-19 pandemic and related lockdowns on child and maternal health, economic hardships, and access to care for children and pregnant women by the Child Health and Mortality Prevention Surveillance (CHAMPS) Network. The data were gathered in Bamako, the capital city of Mali (population ∼2.9 million) between August and September of 2022 through a Health and Demographic Surveillance System (HDSS).

Neurological Symptoms and Cause of Death Among Young Children in Low- and Middle-Income Countries.

Importance: The emergence of acute neurological symptoms in children necessitates immediate intervention. Although low- and middle-income countries (LMICs) bear the highest burden of neurological diseases, there is a scarcity of diagnostic and therapeutic resources. Therefore, current understanding of the etiology of neurological emergencies in LMICs relies mainly on clinical diagnoses and verbal autopsies.

Association Between SARS-CoV-2 Viral Load and COVID-19 Vaccination in 4 Phase 3 Trials.

Coronavirus disease 2019 (COVID-19) vaccines reduce severe disease and mortality and may lessen transmission, measured by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral load (VL). Evaluating vaccine associations in VL at COVID-19 diagnosis in 4 phase 3 randomized, placebo-controlled vaccine trials, July 2020 to July 2021, VL reductions were 2.78 log10 copies/mL (95% confidence interval [CI], 1.

Comparison of causes of stillbirth and child deaths as determined by verbal autopsy and minimally invasive tissue sampling.

In resource-limited settings where vital registration and medical death certificates are unavailable or incomplete, verbal autopsy (VA) is often used to attribute causes of death (CoD) and prioritize resource allocation and interventions. We aimed to determine the CoD concordance between InterVA and CHAMPS's method. The causes of death (CoDs) of children <5 were determined by two methods using data from seven low- and middle-income countries (LMICs) enrolled in the Child Health and Mortality Prevention Surveillance (CHAMPS) network.

Innovative Approach to Accelerate Wound Healing: Synthesis and Validation of Enzymatically Cross-Linked COL-rGO Biocomposite Hydrogels.

In this study, an innovative conductive hybrid biomaterial was synthetized using collagen (COL) and reduced graphene oxide (rGO) in order for it to be used as a wound dressing. The hydrogels were plasticized with glycerol and enzymatically cross-linked with horseradish peroxidase (HRP). A successful interaction among the components was demonstrated by FTIR, XRD, and XPS.

Clinicopathological discrepancies in the diagnoses of childhood causes of death in the CHAMPS network: An analysis of antemortem diagnostic inaccuracies.

Introduction: Determining aetiology of severe illness can be difficult, especially in settings with limited diagnostic resources, yet critical for providing life-saving care. Our objective was to describe the accuracy of antemortem clinical diagnoses in young children in high-mortality settings, compared with results of specific postmortem diagnoses obtained from Child Health and Mortality Prevention Surveillance (CHAMPS).

Methods: We analysed data collected during 2016-2022 from seven sites in Africa and South Asia.

An extremely fast neural mechanism to detect emotional visual stimuli: A two-experiment study.

Defining the brain mechanisms underlying initial emotional evaluation is a key but unexplored clue to understanding affective processing. Event-related potentials (ERPs), especially suited for investigating this issue, were recorded in two experiments (n = 36 and n = 35). We presented emotionally negative (spiders) and neutral (wheels) silhouettes homogenized regarding their visual parameters.

Contrasting magma chemistry in the Candelaria IOCG district caused by changing tectonic regimes.

Iron oxide-copper-gold (IOCG) deposits are a vital source of copper and critical elements for emerging clean technologies. Andean-type IOCG deposits form in continental arcs undergoing extension, and they have a temporal relationship with magmatism although they do not exhibit a close spatial relation with the causative intrusions. The processes required to form IOCG deposits and their potential connections to iron oxide-apatite (IOA)-type mineralization remain poorly constrained, as well as the characteristics of magmatism linked to both deposit types.
