Inflammatory Monocytes Increase Prior to Detectable HIV-1 Rebound Viremia.

The persistence of HIV-1 proviruses in latently infected cells allows viremia to resume upon treatment cessation. To characterize the resulting immune response, we compare plasma proteomics and single-cell transcriptomics of peripheral blood mononuclear cells (PBMCs) before, during, and after detectable plasma viremia. We observe unique transcriptional signatures prior to viral rebound including a significant increase in CD16 monocytes with increased anti-viral gene expression.

Evaluating the psychosocial experiences of participants in HIV cure research before, during, and after analytical treatment interruptions: A longitudinal qualitative study in the United States.

The lack of socio-behavioral research on stress and psychosocial experiences among research participants who undergo analytical treatment interruption (ATI) in HIV cure studies underscores a critical gap in cure science. Existing literature acknowledges mixed and potentially adverse mental health impacts of ATIs among trial participants, but empirical insights before, during, and after clinical studies are scarce. We used longitudinal in-depth interviews with 11 participants in HIV cure-related research to explore their experiences with stress, coping, and psychological well-being before, during, and after an ATI.

Assessing the Agreement Between Diffusion Tension Imaging (DTI) and T2-Weighted MRI Sequence for Biometry of the Fetal Corpus Callosum.

Background/objectives: Little is known about the advantages of Diffusion Tensor Imaging (DTI) when evaluating the fetal corpus callosum (CC), a sensitive indicator for normal brain development. This study evaluates the contribution of DTI compared to T2-weighted imaging to assess fetal CC biometry.

Methods: Data from the fetal MRI exams of singleton pregnancies between July 2017 and 2019 were retrospectively analyzed.

2022 AAHA Canine Vaccination Guidelines (2024 Update).

Vaccination is a cornerstone of canine preventive healthcare and one of the most cost-effective ways of maintaining a dog's health, longevity, and quality of life. Canine vaccination also serves a public health function by forming a barrier against several zoonotic diseases affecting dogs and humans. Canine vaccines are broadly categorized as containing core and noncore immunizing antigens, with administration recommendations based on assessment of individual patient risk factors.
