Antemortem studies pertaining to the manatee cardiovascular and cardiopulmonary systems are limited despite reports of cardiac disease in postmortem specimens. The objective of this project was to develop a technique for echocardiography in the Florida manatee (Trichechus manatus latirostris). Because of their unique anatomy, a ventral approach was employed by use of an echocardiography table designed specifically for this study. Fourteen clinically healthy, free-ranging and captive Florida manatees underwent echocardiography between the fall of 2011 and winter of 2012. Eight females and six males of various age categories were included in the study. Clear visualization of all valves and chambers was accomplished, and length and width measurements of the left atrium, peak aortic flow velocity, and ejection fraction percentage were calculated in most animals. Abnormalities observed during the study included atrioventricular regurgitation and severe right-atrial enlargement. Based on the results of this study, echocardiography in the Florida manatee is possible, which has both clinical and research implications in larger epidemiologic studies evaluating diseases of the cardiopulmonary and cardiovascular systems.

A revolutionary transformation in biomedical imaging is unfolding with the advent of aggregation-induced emission luminogens (AIEgens). These cutting-edge molecules not only overcome the limitations of traditional fluorescent probes but also improve the boundaries of high-contrast imaging. Unlike conventional fluorophores suffering from aggregation-caused quenching, AIEgens exhibit enhanced luminescence when aggregated, enabling superior imaging performance.

Study Objectives: Sleep disorders and/or disordered sleep represent common clinical presentations of pediatric acute-onset neuropsychiatric syndrome (PANS), occurring in up to 80% of affected children, with REM sleep motor disinhibition being a prevalent feature. To date, limited polysomnographic (PSG) studies have been conducted. Therefore, the objective of this study was to evaluate the PSG characteristics of a cohort of children with PANS, focusing particularly on REM sleep without atonia (RSWA) as assessed by the REM atonia index (RAI), and to compare these characteristics with those of a control group.

It has been observed that diseases such as rhinitis and asthma not only affect the physical health of individuals but can also significantly impact their psychological well-being. The aim of this study is to analyze the relationship between allergic rhinitis (AR), non-allergic rhinitis (NAR), and asthma with symptoms of depression in adults. Comparative cross-sectional study.

Purpose To explore the diffusion characteristics of hypertrophic cardiomyopathy (HCM) using in vivo cardiac diffusion-tensor imaging (cDTI) and to determine whether cDTI could help identify abnormal myocardium beyond cardiac MRI findings of fibrosis and hypertrophy. Materials and Methods In this prospective study conducted from April to August 2023, participants with HCM and healthy volunteers were enrolled for cardiac MRI evaluation, including cine, late gadolinium enhancement (LGE), T1 mapping, and cDT imaging, using a 3.0-T scanner.

People living with HIV (PLWH) beginning antiretroviral therapy (ART) retain a high burden of cytomegalovirus (CMV). CMV has been implicated in atherosclerosis in healthy adults, and a role in PLWH is plausible. Atherosclerosis has also been linked with γδ T cells and CMV seropositivity with altered γδ T cell profiles in other populations.
