Patients who overstay in the ICU after being deemed transfer-ready are unlikely to be benefiting from critical care, but impact hospital throughput and resource utilization. Prospective investigation into this practice may provide further confirmation of its feasibility and safety.
The practice of directly discharging MICU patients home does not negatively influence patient outcomes. Patients who overstay in the ICU after being deemed transfer-ready are unlikely to be benefiting from critical care, but impact hospital throughput and resource utilization. Prospective investigation into this practice may provide further confirmation of its feasibility and safety.Chronic infection with human immunodeficiency virus (HIV) can cause progressive loss of immune cell function, or exhaustion, which impairs control of virus replication. However, little is known about the development and maintenance, as well as heterogeneity of immune cell exhaustion. Here, we investigated the effects of HIV infection on immune cell exhaustion at the transcriptomic level by analyzing single-cell RNA sequencing of peripheral blood mononuclear cells from four healthy subjects (37,847 cells) and six HIV-infected donors (28,610 cells). We identified nine immune cell clusters and eight T cell subclusters, and three of these (exhausted CD4+ and CD8+ T cells and interferon-responsive CD8+ T cells) were detected only in samples from HIV-infected donors. An inhibitory receptor KLRG1 was identified in a HIV-1 specific exhausted CD8+ T cell population expressing KLRG1, TIGIT, and T-betdimEomeshi markers. Ex-vivo antibody blockade of KLRG1 restored the function of HIV-specific exhausted CD8+ T cells demonstrating the contribution of KLRG1+ population to T cell exhaustion and providing an immunotherapy target to treat HIV chronic infection. These data provide a comprehensive analysis of gene signatures associated with immune cell exhaustion during HIV infection, which could be useful in understanding exhaustion mechanisms and developing new cure therapies.Neutrophils infected with Mycobacterium tuberculosis (Mtb) predominate in tuberculosis patients' lungs. Neutrophils phagocytose the pathogen, but the mechanism of pathogen elimination is controversial. Macroautophagy/autophagy, a crucial mechanism for several neutrophil functions, can be modulated by immunological mediators. The costimulatory molecule SLAMF1 can act as a microbial sensor in macrophages being also able to interact with autophagy-related proteins. Here, we demonstrate for the first time that human neutrophils express SLAMF1 upon Mtb-stimulation. Furthermore, SLAMF1 was found colocalizing with LC3B+ vesicles, and activation of SLAMF1 increased neutrophil autophagy induced by Mtb. Finally, tuberculosis patients' neutrophils displayed reduced levels of SLAMF1 and lower levels of autophagy against Mtb as compared to healthy controls. Altogether, these results indicate that SLAMF1 participates in neutrophil autophagy during active tuberculosis.

Extending this work to pediatric anxiety, we report two studies utilising eye tracking (Study 1) and functional magnetic resonance imaging (Study 2). Both studies use a visual search paradigm to examine anxiety-related differences in the impact of threat on attentional control at varying levels of task difficulty. In Study 1, youth ages 8-18 years (N = 109), completed the paradigm during eye tracking. Results indicated that youth with more severe anxiety took longer to fixate on and identify the target, specifically on difficult trials, compared to youth with less anxiety. However, no anxiety-related effects of emotional distraction (faces) emerged. In Study 2, a separate cohort of 8-18-year-olds (N = 72) completed a similar paradigm during fMRI. Behaviourally, youth with more severe anxiety were slower to respond on searches following non-threatening, compared to threatening, distractors, but this effect did not vary by task difficulty. The same interaction emerged in the neuroimaging analysis in the superior parietal lobule and precentral gyrus-more severe anxiety was associated with greater brain response following non-threatening distractors. Theoretical implications of these inconsistent findings are discussed.
Adenovirus infection can cause severe pneumonia even in immunocompetent adults. However, there is limited data on the benefits of cidofovir treatment in severe adenovirus pneumonia. The objective of this study was to evaluate the association of cidofovir treatment with clinical improvement in immunocompetent adult patients with severe adenovirus pneumonia.

We evaluated 22 male patients who admitted to intensive care unit (ICU) with severe adenovirus pneumonia between January 2014 and December 2019. read more The patients were divided into 2 groups, patients treated with cidofovir or not. Clinical outcomes including time to defervescence and stopping of oxygen supplement, length of stay in ICU and hospital, and the need for mechanical ventilation (MV) and extracorporeal membrane oxygenation (ECMO) were compared between the 2 groups.

Among 22 patients, 13 patients (59%) were treated with cidofovir and 9 (41%) were not. The difference in mean time (95% confidence interval [CI]) to defervescence and stopping of oxygen supplement between cidofovir group and no cidofovir group was 2.
