Immunogenicity and safety of varying dosages of a fifth-wave influenza A/H7N9 inactivated vaccine given with and without AS03 adjuvant in healthy adults.

Background: Human infections with the avian influenza A(H7N9) virus were first reported in China in 2013 and continued to occur in annual waves. In the 2016/2017 fifth wave, Yangtze River Delta (YRD) lineage viruses, which differed antigenically from those of earlier waves, predominated.

Methods: In this phase 2 double-blinded trial we randomized 720 adults ≥ 19 years of age to receive two injections of a YRD lineage inactivated A/Hong Kong/125/2017 fifth-wave H7N9 vaccine, given 21 days apart, at doses of 3.

Factors Associated With Anal High-Grade Intraepithelial Lesions and Carcinoma Among Young Men Who Have Sex With Men and Transgender Women With HIV in Atlanta.

Objective: This study aimed to evaluate factors associated with anal high-grade intraepithelial lesions (HSIL) and anal carcinoma among young men who have sex with men (MSM) and transgender women (TW) with HIV in Atlanta, GA, to better inform screening guidelines and preventative measures.

Materials And Methods: Cross-sectional retrospective chart review was completed for cisgender MSM and TW with HIV aged 13-25 years at the Grady Ponce and Family Youth Clinic in Atlanta, GA, from 2009 to 2020. High-grade anal disease was defined as anal intraepithelial neoplasia (AIN) 2, 3, or anal carcinoma (AIN 2+).

"An Extra Variable to Consider"-Vaccine-Induced Seropositivity and Adolescent HIV Vaccine Clinical Trials.

Our study explores the understanding of vaccine-induced seropositivity (VISP) and its potential impact on US adolescents' and caregivers' willingness to participate in adolescent HIV vaccine clinical trials. Findings from in-depth interviews suggest that addressing concerns about VISP will be essential for future pediatric HIV vaccine trials in the United States.

Raltegravir-associated Drug-Reaction With Eosinophilia and Systemic Symptoms Syndrome in a Pediatric Patient Without Characteristic Human Leukocyte Antigen B*57:01 or B*53:01 alleles.

We present the first published case of raltegravir-associated drug-reaction with eosinophilia and systemic symptoms (DRESS) syndrome in a child without characteristic human leukocyte antigen haplotypes HLA-B*57:01 or HLA-B*53:01. A 4-year-old African American female with perinatally acquired human immunodeficiency virus infection was hospitalized for DRESS after starting a raltegravir-based antiretroviral regimen.

Innovations in HIV-1 Vaccine Design.

Purpose: The field of HIV-1 vaccinology has evolved during the last 30 years from the first viral vector HIV gene insert constructs to vaccination regimens using a myriad of strategies. These strategies now include germline-targeting, lineage-based, and structure-guided immunogen design. This narrative review outlines the historical context of HIV vaccinology and subsequently highlights the scientific discoveries during the last 6 years that promise to propel the field forward.

Performance of Interferon-Gamma Release Assays for Tuberculosis Screening in Pediatric Inflammatory Bowel Disease.

Objectives: The aim of the study was to analyze the diagnostic accuracy and utility of QuantiFERON-TB Gold In-Tube, an interferon-gamma release assay (IGRA), as a screening tool for latent tuberculosis infection (LTBI) in pediatric patients with inflammatory bowel disease (IBD) undergoing treatment with anti-tumor necrosis factor (anti-TNF) medications. To describe cases of tuberculosis in the pediatric IBD population, TB treatment courses, outcomes, and their effect on IBD management.

Methods: A single-center, retrospective cohort study of pediatric IBD patients who underwent tuberculosis screening.

Prevalence of Anal Squamous Intraepithelial Lesions in HIV-1-Infected Young Men Who Have Sex With Men and Transwomen.

Objective: Anal cancer rates are increasing among HIV-infected persons. Although an efficacious human papillomavirus (HPV) vaccine is available, HPV vaccination rates remain low. Therefore, providers perform anal cancer screening, but there is no consensus on the optimal methods or timing of screening.

Gram-Positive Rods on a Cerebrospinal Fluid Gram Stain.

Cerebrospinal fluid (CSF) access device placement in the pediatric population presents challenges due to the development of infections following placement, access or revision, and/or shunt malfunctions. Here we report an unusual pediatric case of ventriculitis/VP shunt (VPS) infection and associated pseudocyst with an emphasis on the importance of VPS removal in clearing the infection due to biofilm formation.

Regular Marijuana Use is Associated with Poor Viral Suppression in HIV-Infected Adolescents and Young Adults.

There is a paucity of data regarding the impact of drug use on HIV suppression and care retention among adolescents and young adults (AYAs). We recruited a clinic-based sample of HIV infected AYAs to assess the prevalence of self-reported drug use. Clinical data, including retention and viral suppression, were abstracted from the electronic medical record.
