Urgent findings in CT chest examinations: Radiography and medical students' capabilities and learning perspectives - a preliminary study.

Introduction: Radiography and medical students (RMS), upon graduation, require capabilities to provide life-saving care through identification and communication of urgent findings on radiological imaging. This preliminary study investigated RMS' ability to identify and categorise urgent findings on CT examinations. It also explored their experiences of image interpretation education.

Immunogenicity and Safety According to Immunosuppressive Drugs and Different COVID-19 Vaccine Platforms in Immune-Mediated Disease: Data from SAFER Cohort.

Background/objectives: The effectiveness of COVID-19 vaccine in patients with immune-mediated inflammatory diseases (IMID) depends on the underlying disease, immunosuppression degree and the vaccine regimens. We evaluate the safety and immunogenicity of different COVID-19 vaccine schedules.

Methods: The SAFER study: "Safety and effectiveness of the COVID-19 Vaccine in Rheumatic Disease", is a Brazilian multicentric prospective observational phase IV study in the real-life.

Fannyhessea vaginae and clearance of Lactobacillus iners are associated with incident non-chlamydial non-Mycoplasma genitalium urethritis in men who have sex with women.

Background: The etiology of nongonococcal urethritis (NGU) is incompletely understood. We sought to determine if genitourinary bacterial diversity or specific taxa were associated with incident NGU.

Methods: From August 2014-July 2018, men who have sex with women attending a sexual health clinic were clinically evaluated, including Mycoplasma genitalium (MG) and Chlamydia trachomatis (CT) testing, at enrollment and six monthly visits.

ERH Enables Early Embryonic Differentiation and Overlays H3K9me3 Heterochromatin on a Cryptic Pluripotency H3K9me3 Landscape in Somatic Cells.

Enhancer of Rudimentary Homolog (ERH) is an evolutionarily conserved protein originally characterized in fission yeast and recently shown to maintain H3K9me3 in human fibroblasts . Here, we find that ERH depletion in fibroblasts reverts the H3K9me3 landscape to an embryonic stem cell (ESC) state and enables activation of naïve and pluripotency genes and transposable elements during induced pluripotent stem cell (iPSC) reprogramming. We find that ERH similarly represses totipotent and alternative lineage programs during mouse preimplantation development and is required for proper segregation of the inner cell mass and trophectoderm cell lineages.

Time-dependent Changes in Shrimp Armor and Escape Kinematics under Ocean Acidification and Warming.

Pandalid shrimp use morphological and behavioral defenses against their numerous fish and invertebrate predators. Their rapid tail-flip escape and rigid exoskeleton armor may be sensitive to changes in ocean temperature and carbon chemistry in ways that alter their efficacy and impact mortality. Here we tested the hypothesis that ocean warming and acidification conditions affect the antipredator defenses of Pandalus gurneyi.
