Study protocol for a multi-center stepped-wedge cluster randomized trial to explore the usability and outcomes among young people living with HIV in Kiambu and Kirinyaga counties of Kenya, using an online health portal.

While the incidence of Human Immunodeficiency Virus (HIV) infection is decreasing in most age groups worldwide, it is rising among adolescents and young adults, who also face a higher rate of HIV-related deaths. This tech-savvy demographic may benefit from an online patient portal designed to enhance patient activation-empowering them to manage their health independently. However, the effectiveness of such digital health interventions on young HIV patients in Kenya remains uncertain.

Neutralizing antibody correlate of protection against severe-critical COVID-19 in the ENSEMBLE single-dose Ad26.COV2.S vaccine efficacy trial.

Assessment of immune correlates of severe COVID-19 has been hampered by the low numbers of severe cases in COVID-19 vaccine efficacy (VE) trials. We assess neutralizing and binding antibody levels at 4 weeks post-Ad26.COV2.

Conspiracy mentality in autistic and non-autistic individuals.

Background: Belief in conspiracy theories has emerged across times and cultures. While previous accounts attributed conspiracy beliefs to mental health conditions, accumulating research suggests that conspiracy theories are common among the general population. In the present study we examined whether conspiracy mentality - that is, a general predisposition to believe conspiracy theories - differed between a group of autistic adults and a general population sample.

Pre- and post-Ad26.COV2·S booster dose antibody levels predict COVID-19 disease risk.

Identifying immune correlates of risk following COVID-19 vaccine boosters has become paramount as a result of the challenges in generating additional efficacy data. The trial data described here was collected in the United States, with a large part of the study conduct coinciding with the emergence of the SARS-CoV-2 Omicron BA.1 variant.

Unraveling clonal CD8 T cell expansion and identification of essential factors in γ-herpesvirus-induced lymphomagenesis.

Alcelaphine gammaherpesvirus 1 (AlHV-1) asymptomatically persists in its natural host, the wildebeest. However, cross-species transmission to cattle results in the induction of an acute and lethal peripheral T cell lymphoma-like disease (PTCL), named malignant catarrhal fever (MCF). Our previous findings demonstrated an essential role for viral genome maintenance in infected CD8 T lymphocytes but the exact mechanism(s) leading to lymphoproliferation and MCF remained unknown.
