Furthermore, the BPQ and subscales of the MAIA predicted neuroticism in different directions suggesting the two measures assess different constructs and thus strengthened support for a multidimensional consideration of interoception. The results have clinical implications, including the targeting of contemplative training approaches for individuals demonstrating high interoceptive sensibility and neurotic traits to improve the mental well-being of healthy individuals and clinical populations.This article offers a legal-ethical analysis of recent UK and Dutch proposals to regulate surrogacy proactively through a national system of pre-conception authorization of surrogacy agreements. Within such a system, authorities are already before conception called upon to examine and assess contractual arrangements between the intending parents and the prospective surrogate mother. This regulatory approach is presented by its advocates as a win-win for all parties involved; as bringing family law in line with the changed social reality of creating families; and as maintaining a non-permissive approach toward commercial surrogacy. In this article, we critically examine these claims. Our analysis suggests that the proposed systems may result in the facilitation of surrogacy practices with commercial, commodifying and exploitative dimensions. Moreover, although these frameworks are presented as merely regulating something that is already taking place, they silently introduce a radically new and, as we shall argue, highly problematic legal-ethical approach to surrogacy.Background Chest radiograph (CXR) is typically obtained early in patients admitted with COVID-19 and may help guide prognosis and initial management decisions. Objective To assess the performance of a severity scoring system on admission CXR in predicting hospital outcomes in patients admitted with COVID-19. Methods This retrospective study included 240 patients (142 men, 98 women; median age 65 [50-80]) admitted to the hospital from 3/16/2020 to 4/30/2020 with COVID-19 confirmed by real-time reverse transcriptase-polymerase chain reaction and who underwent CXR within 24 hours of admission. Three chest radiologists and three radiology residents independently scored patients' admission CXR using a 0 to 24-point composite scale (sum of 0-3 scores for extent and severity of disease in upper and lower lung zones). The score's interrater reliability score was assessed using Kendall's W statistic. The six readers' scores were averaged for further analyses. Demographic variables, clinical characteristics, and admissdecision making early in the disease course of COVID-19.BACKGROUND An association in children between linear gadolinium-based contrast agents and intracranial gadolinium retention is recognized; the relationship with macrocyclic gadolinium-based contrast agent (mcGBCAs) remains incompletely understood. OBJECTIVE To assess whether 10 or more administrations of the mcGBCA gadobutrol is associated with increased signal intensity (SI) in the dentate nucleus (DN) and globus pallidus (GP) on unenhanced T1-weighted imaging (T1WI) in children and to explore clinical variables potentially associated with T1 hyperintensity. METHODS Twenty-five children (13 boys, 12 girls; mean age 7±4 years, range 2-18 years) who underwent at least 10 (mean 15±6; range 10-34) contrast-enhanced MRI examinations using exclusively gadobutrol, and 25 age- and sex-matched control patients without gadolinium exposure who underwent MRI, were identified. Two observers in consensus assessed visual T1 hyperintensity in the DN and GP using a 3-point scale. One observer placed ROIs on T1WI in the DN, G, p=0.36; r=0.047, p=0.82), or cumulative mcGBCA dose (r=0.434, p=0.07; r=0.270, p=0.19). Interobserver and intraobserver agreement was substantial for DN-to-MCP SI and GP-to-TH SI ratios (Ro 0.931-0.974). CONCLUSION Ten or more serial gadobutrol administrations was not associated with T1 hyperintensity in the DN or GP in children. CLINICAL IMPACT Selection of gadobutrol as an MRI contrast agent may reduce risk of gadolinium retention in children. The findings may help guide practices for GBCA administration in children.The American College of Radiology (ACR) Thyroid Imaging Reporting and Data System (TI-RADS) is an ultrasound-based risk stratification system (RSS) for thyroid nodules that was released in 2017. Since publication, research has shown that ACR TI-RADS has a higher specificity than other RSSs and reduces the number of unnecessary biopsies of benign nodules compared with other systems by 19.9-46.5%. The risk of missing significant cancers using ACR TI-RADS is mitigated by the follow-up recommendations for nodules that do not meet criteria for biopsy. In practice, after a nodule's ultrasound features have been enumerated, the ACR TI-RADS points-based approach leads to clear management recommendations. Practices seeking to implement ACR TI-RADS must engage their radiologists in understanding how the system addresses the problems of thyroid cancer overdiagnosis and unnecessary surgeries by reducing unnecessary biopsies. This review compares ACR TI-RADS to other RSSs and explores key clinical questions faced by practices considering its implementation. We also address the challenge of reducing interobserver variability in assigning ultrasound features. Finally, we highlight emerging imaging techniques and recognize the ongoing international effort to develop a system that harmonizes multiple RSSs, including ACR TI-RADS.Mitochondrial dysfunction is an early, imminent event in neurodegenerative disorders including Parkinson disease (PD) and Alzheimer disease (AD). The enzymatic pair PINK1 and PRKN/Parkin recognize and transiently label damaged mitochondria with ubiquitin (Ub) phosphorylated at Ser65 (p-S65-Ub) as a signal for degradation via the autophagy-lysosome system (mitophagy). Despite its discovery in cell culture several years ago, robust and quantitative detection of altered mitophagy in vivo has remained challenging. MRTX849 cost Here we developed a sandwich ELISA targeting p-S65-Ub with the goal to assess mitophagy levels in mouse brain and in human clinical and pathological samples. We characterized five total Ub and four p-S65-Ub antibodies by several techniques and found significant differences in their ability to recognize phosphorylated Ub. The most sensitive antibody pair detected recombinant p-S65-Ub chains in the femtomolar to low picomolar range depending on the poly-Ub chain linkage. Importantly, this ELISA was able to assess very low baseline mitophagy levels in unstressed human cells and in brains from wild-type and prkn knockout mice as well as elevated p-S65-Ub levels in autopsied frontal cortex from AD patients vs.
