Collegiate athletes with ADHD have an increased prevalence rate of diagnosed sport-related concussions compared to those without ADHD; however, this developmental disorder may not influence injury nondisclosure decisions.Intestinal permeability is an important diagnostic marker, yet its determination by established tests, which measure the urinary excretion of orally administered tracer molecules, is time consuming and can only be performed prospectively. Here, we aim to validate proposed surrogate biomarkers, which allow measuring intestinal permeability more easily. In this cross-sectional study, we included two independent cohorts comprising nonobese (Healthy cohort, n = 51) and individuals with obesity (Obesity cohort, n = 27). The lactulose/mannitol (lac/man) ratio was determined in all individuals as an established marker of intestinal permeability. Furthermore, we measured six potential surrogate biomarkers, being albumin, calprotectin, and zonulin, measured in feces, as well as intestinal fatty acid binding protein (I-FABP), lipopolysaccharide binding protein (LBP) and zonulin, measured in plasma. Correlation analyses and multiple linear regression models were conducted to assess possible associations between the estaracer-based tests may not be feasible.The prevalence of problem gambling in the correctional system is about 10 times higher than in the general population, but programming for gambling problems in the correctional system is scarce. Examined barriers to treatment for problem gamblers in the correctional system, sex or gender differences, and options for program design. We conducted interviews with 16 experts who had worked with problem gamblers in the correctional system and analyzed the data in terms of themes. For barriers, the experts discussed a lack of awareness about problem gambling, as well as stigmatization and lockdowns. Experts described the content of current programs as equally applicable to both men and women, but that emotional components were more important for women. Finally, the experts had mixed views on whether programming should be integrated with other programs such as substance abuse. Programming implications for this population are discussed.In vitro biomarkers to assess cystic fibrosis transmembrane conductance regulator activity are desirable for precision modulator selection and as a tool for clinical trials. Here, we describe an organoid swelling assay derived from human nasal epithelia using commercially available reagents and equipment and an automated imaging process. Cells were collected in nasal brush biopsies, expanded in vitro, and cultured as spherical organoids or as monolayers. Organoids were used in a functional swelling assay with automated measurements and analysis, whereas monolayers were used for short-circuit current measurements to assess ion channel activity. Clinical data were collected from patients on modulators. Relationships between swelling data and short-circuit current, as well as between swelling data and clinical outcome measures, were assessed. The organoid assay measurements correlated with short-circuit current measurements for ion channel activity. The functional organoid assay distinguished individual responses as well as differences between groups. The organoid assay distinguished incremental drug responses to modulator monotherapy with ivacaftor and combination therapy with ivacaftor, tezacaftor, and elexacaftor. The swelling activity paralleled the clinical response. In conclusion, an in vitro biomarker derived from patients' cells can be used to predict responses to drugs and is likely to be useful as a preclinical tool to aid in the development of novel treatments and as a clinical trial outcome measure for a variety of applications, including gene therapy or editing.Electronic (e-) cigarettes are growing in popularity despite uncertainties regarding their long-term health implications. selleck inhibitor The link between cigarette smoking and initiation of chronic lung disease took decades to unpick so in vitro studies mimicking e-cigarette exposure aim to detect early indicators of harm. In response to e-cigarette exposure, alveolar macrophages adopt a pro-inflammatory phenotype of increased secretion of proinflammatory cytokines, reduction in phagocytosis and efferocytosis and reactive oxygen species generation. These effects are largely driven by free radical exposure, changes in PI3K/Akt signalling pathways, nicotine-induced reduction in phagocytosis receptors and impaired lipid homeostasis leading to a foam-like lipid laden phenotype. Neutrophils exhibit disrupted chemotaxis and transmigration to chemokines, reduced phagocytosis and bacterial killing and an increase in protease secretion without corresponding antiproteases in response to e-cigarette exposure. This is driven by an altered ability to respond and polarise towards chemoattractants, an activation of the p38 MAPK signalling pathway and inability to assemble NADPH oxidase. E-cigarettes induce lung epithelial cells to display decreased ciliary beat frequency and ion channel conductance as well as changes in chemokine secretion and surface protein expression. Changes in gene expression, mitochondrial function and signalling pathways have been demonstrated in lung epithelial cells to explain these changes. Many functional outputs of alveolar macrophages, neutrophils and lung epithelial cells have not been fully explored in the context of e-cigarette exposure, and the underlying driving mechanisms are poorly understood. This review discusses current evidence surrounding the effects of e-cigarettes on alveolar macrophages, neutrophils and lung epithelial cells with particular focus on the cellular mechanisms of change.The renin-angiotensin system (RAS) is fundamental to COVID-19 pathobiology, due to the interaction between the SARS-CoV-2 virus and the angiotensin-converting enzyme 2 (ACE2) coreceptor for cellular entry. The prevailing hypothesis is that SARS-CoV-2-ACE2 interactions lead to an imbalance of the RAS, favoring proinflammatory angiotensin II (ANG II)-related signaling at the expense of the anti-inflammatory ANG-(1-7)-mediated alternative pathway. Indeed, multiple clinical trials targeting this pathway in COVID-19 are underway. Therefore, precise measurement of circulating RAS components is critical to understand the interplay of the RAS on COVID-19 outcomes. Multiple challenges exist in measuring the RAS in COVID-19, including improper patient controls, ex vivo degradation and low concentrations of angiotensins, and unvalidated laboratory assays. Here, we conducted a prospective pilot study to enroll 33 patients with moderate and severe COVID-19 and physiologically matched COVID-19-negative controls to quantify the circulating RAS.
