Lipidomic changes were causally linked to metabolic diseases, but the scenario for colorectal cancer (CRC) is less clear. We investigated the CRC lipidome for putative tumor-specific alterations through analysis of 3 independent retrospective patient cohorts from 2 clinical centers, to derive a clinically useful signature.
Quantitative comprehensive lipidomic analysis was performed using direct infusion electrospray ionization coupled with tandem mass spectrometry (ESI-MS/MS) and high-resolution mass spectrometry (HR-MS) on matched nondiseased mucosa and tumor tissue in a discovery cohort (n= 106). Results were validated in 2 independent cohorts (n= 28, and n= 20), associated with genomic and clinical data, and lipidomic data from a genetic mouse tumor model (Apc
).
Significant differences were found between tumor and normal tissue for glycero-, glycerophospho-, and sphingolipids in the discovery cohort. Comparison to the validation collectives unveiled that glycerophospholipids showed high interpatienncer-associated glycerolipid and sphingolipid metabolism may lead to novel therapeutic strategies.
To describe the value of integrating phenotype/genotype data, disease staging, and evaluation of functional vision in patient-centered management of retinal dystrophies.
(1) Cross-sectional structure-function and retrospective longitudinal studies to assess the correlations between standard fundus autofluorescence (FAF), optical coherence tomography, visual acuity (VA), and perimetry (visual field [VF]) examinations to evaluate photoreceptor functional loss in a cohort of patients with rod-cone dystrophy (RCD); (2) flood-illumination adaptive optics (FIAO) imaging focusing on photoreceptor misalignment and orientation of outer segments; and (3) evaluation of the impact of visual impairment in daily life activities, based on functional (visual and mobility) vision assessment in a naturalistic environment in visually impaired subjects with RCD and subjects treated with Luxturna® for RPE65-related Leber congenital amaurosis before and after therapy.
The results of the cross-sectional transversal study showvel. 4SC-202 in vivo At high illumination level (235 lux), VF was a predictor for all mobility performance models. Under low illumination (1 and 2 lux), VF was the most significant predictor of mobility performance variables, while CS best explained the number of collisions and segments. In subjects treated with Luxturna®, a very favorable impact on travel speed and reduction in the number of collisions, especially at low luminance, was observable 6 months following injection, in both children and adults.
Our results suggest the benefit of development and implementation of quantitative and reproducible tools to evaluate the status of photoreceptors and the impact of both visual impairment and novel therapies in real-life conditions.

To reach this goal, the monolayers and bilayers composed of phosphatidylcholine, phosphatidyethanol amine and ergosterol, differing in the concentration of sterol, were used as model membrane systems. The impact of the essential oil and its major terpenes on one component ergosterol film was also investigated. It was found that pure isolated terpenes, in contrast to the hop oil being the mixture of them, do not incorporate into pure ergosterol membrane, however, they cause the loss of monolayer material from the interface. These results are in contrast to the effect of these terpenes on phospholipid films reported previously and they may suggest a strong effect of ergosterol on the behavior of terpenes in the mixed systems. Surprisingly, for model membranes, the effect of myrcene was qualitatively similar to the effect of the hop oil and ergosterol was found to regulate the incorporation of both these substances into the film. In contrast, very strong correlation between ergosterol content and the action of humulene was found. Namely, the ability of humulene to change model membrane properties was found to increase with ergosterol concentration. Additionally, the differentiating effect of ergosterol on humulene action in membranes was much more pronounced than for myrcene or the hop oil. Interestingly, at the highest ergosterol level the influence of humulene was even stronger than the effect of the hop oil. This is very important finding suggesting that ergosterol may regulate the sensitivity of particular membrane to the impact of humulene. Summarizing, ergosterol substantially differentiates the effect of the hop oil, myrcene and humulene on the lipid systems and it can be the molecule important for antifungal effect of the essential oil and terpenes.
To characterize elective, post-neonatal operative circumcision at US children's hospitals, in the context of established sociodemographic disparities in access to neonatal circumcision.
A retrospective cohort study was performed of boys undergoing elective, operative circumcision at the 23 Pediatric Health Information System (PHIS) hospitals who contributed data from 2004-2018. Boys >=36 months' and those with congenital anomalies of the penis were excluded. Bivariate statistics were used to compare the circumcision cohort to a referent cohort of boys undergoing other ambulatory surgery or having an observational hospital stay.
The annual median number of operative circumcisions per hospital increased during the study (72 [IQR 54-162] to 136 [IQR 88-266], P=.003). Boys undergoing circumcision were mostly non-Hispanic White (46.7%) or non-Hispanic Black (30.9%), in the lowest income quartile (26.6%), from the Southern US (51.5%), and publicly-insured (60.5%). When compared to the reference cohort, boys undergoing circumcision were more likely to be non-Hispanic Black (30.9 vs 15.7%, P = .001) and publicly-insured (60.5 vs 45.9%, P = . 001).
The number of post-neonatal operative circumcisions performed at US children's hospitals nearly doubled from 2004 to 2018. Study findings suggest an emerging healthcare disparity, with non-Hispanic Black boys of lower socioeconomic status undergoing more post-neonatal operative circumcisions that are more expensive and higher risk.
