Mobile technology access and use among youth in Nairobi, Kenya: implications for mobile health intervention design.

Background: Social media can be used to support the health of underserved youth beyond clinical settings. Young people are avid users of social media, but estimates of smartphone access among youth in sub-Saharan Africa are lacking, making it difficult to determine context-appropriateness of online and social media interventions.

Methods: We conducted a cross-sectional observational survey assessing technology access and use among youth aged 14-24 receiving general outpatient or human immunodeficiency virus (HIV) care in three hospitals in Nairobi, Kenya.

Prevalence of rotavirus among older children and adults with diarrhea: A systematic review and meta-analysis.

Background: Older children and adults are susceptible to rotavirus, but the extent to which rotavirus affects this population is not fully understood, hindering accuracy of global rotavirus estimations.

Objective: To determine what proportion of diarrhea cases are due to rotavirus among persons ≥ 5 years old and to estimate this proportion by age strata.

Methods: We conducted a systematic review and meta-analysis using the PRISMA guidelines.

Gastrointestinal manifestations of human immunodeficiency virus and coronavirus disease 2019: Understanding the intersecting regions between the two epidemics.

In March 2020, the World Health Organization declared coronavirus disease (COVID-19) a pandemic. As of February 2021, there were 107 million COVID-19 cases worldwide. As a comparison, there are approximately 38 million people living with human immunodeficiency virus (PLHIV) worldwide.

Human immunodeficiency virus (HIV) and coronavirus disease 2019; impact on vulnerable populations and harnessing lessons learnt from HIV programmes.

Coronavirus disease 2019 (COVID-19) can act as a dual prong attack against management of people living with human immunodeficiency virus (HIV); it induces harm on both individual and national levels. People living with HIV may show rapid deterioration in severe acute respiratory syndrome coronavirus 2 infection as a result of physiological or psychological vulnerability. Additionally, the spread of COVID-19-especially in low- and middle-income countries-may limit HIV control measures, delivery and linkage to HIV care and prevention.

Immunogenicity of Alternative Dosing Schedules for HPV Vaccines among Adolescent Girls and Young Women: A Systematic Review and Meta-Analysis.

Alternative dosing schedules for licensed human papilloma virus (HPV) vaccines, particularly single dose and extended intervals between doses (>12 months), are being considered to address vaccine shortages and improve operational flexibility. We searched PUBMED/MEDLINE for publications reporting immunogenicity data following administration of one of the licensed HPV vaccines (2vHPV, 4vHPV, and 9vHPV) to females aged 9-26 years. We conducted non-inferiority analyses comparing alternative to standard schedules using mixed effects meta-regression controlling for baseline HPV status and disaggregated by vaccine, subtype, time point, and age group (9-14 and 15-26 years).
