In the multivariable model adjusting for 11 confounders, higher presenting sRAGE level was associated with significantly lower risk of intensive care use (OR for each one-log increment, 0.39; 95%CI 0.16-0.91; P=0.03) and significantly lower rate of recurrent wheeze (HR 0.58; 95%CI 0.36-0.94; P=0.03). In mediation analysis, the direct effect was significant (HR 0.60; 95%CI 0.37-0.97; P=0.04) while the indirect effect was not (P=0.30).

Serum sRAGE levels were inversely associated with acute and chronic morbidities of bronchiolitis. Effect of sRAGE on development of recurrent wheeze is potentially driven through pathways other than acute severity of bronchiolitis.

We examined the health disparities of older adults (age 50 and older) in California at the intersection of sexual identity and Latinx ethnicity, by comparing the prevalence of health outcomes of four groups LGB (lesbian, gay, and bisexual) Latinx, straight Latinx, LGB non-Latinx, and straight non-Latinx older adults.

Data were from the 2015-2016 California Health Interview Survey. Multivariate logistic regressions tested differences among the four groups and the effect of covariates on prevalence of mental and physical health outcomes. We compared LGB and straight people within the same ethnic groups and Latinx and non-Latinx people within the same sexual identity groups to understand the intersectional effect of Latinx ethnicity and LGB identity.

Tests by sexual identity showed that among Latinx older adults, more LGB than non-LGB people experienced serious psychological distress. Among non-Latinx older adults, there were no health disparities due to sexual identity. Tests by Latinx ethnicity showed theting LGB older adults should take a comprehensive approach to understand their experiences as ethnic minorities.Cellular heterogeneity is a hallmark of advanced cancers and has been ascribed in part to a population of self-renewing, therapeutically resistant cancer stem cells (CSCs). Glioblastoma (GBM), the most common primary malignant brain tumor, has served as a platform for the study of CSCs. In addition to illustrating the complexities of CSC biology, these investigations have led to a deeper understanding of GBM pathogenesis, revealed novel therapeutic targets, and driven innovation towards the development of next-generation therapies. While there continues to be an expansion in our knowledge of how CSCs contribute to GBM progression, opportunities have emerged to revisit this conceptual framework. In this review, we will summarize the current state of CSCs in GBM using key concepts of evolution as a paradigm (variation, inheritance, selection, and time) to describe how the CSC state is subject to alterations of cell intrinsic and extrinsic interactions that shape their evolutionarily trajectory. We identify emerging areas for future consideration, including appreciating CSCs as a cell state that is subject to plasticity, as opposed to a discrete population. These future considerations will not only have an impact on our understanding of this ever-expanding field but will also provide an opportunity to inform future therapies to effectively treat this complex and devastating disease.

A simple, rapid and sensitive method coupling ultrasound-assisted dispersive liquid-liquid microextraction (DLLME) with ultra-high performance liquid chromatography-tandem mass spectrometry was developed for the simultaneous determination of malachite green (MG) and crystal violet (CV) in different water samples.

In ultrasound-assisted DLLME procedure, several parameters affecting the extraction efficiency, including pH, type and volume of the extraction and dispersive solvents, extraction time, ionic strength, were optimized to improve the accuracy and precision of this method.

MG and CV were extracted and preconcentrated using dichloromethane and acetonitrile as the extraction and dispersive solvents, respectively.

Under the optimum conditions, the proposed method affords good linearity in the range of 0.40-20.0ng/L, and the limit of detections were 0.21 and 0.32ng/L for MG and CV, respectively. The recoveries of the method at three spiked levels were in the range of 83.4-94.2% with relative standard deviations lower than 4.7% (n=3).

Satisfactorily, no significant matrix effect has been found as the data ranged between 68% and 102%.

IDH-wildtype (IDHwt) grade II gliomas are a rare and heterogeneous entity. Survival and prognostic factors are poorly defined.

We searched retrospectively all patients diagnosed with diffuse WHO grade II and III gliomas at our center (1989-2020).

Out of 517 grade II gliomas, 47 were "diffuse astrocytomas, IDHwt". Tumors frequently had fronto-temporo-insular location (28/47, 60%) and infiltrative behavior. We found TERT promoter mutations (23/45, 51%), whole chromosome 7 gains (10/37, 27%), whole chromosome 10 losses (10/41, 24%), and EGFR amplifications (4/43, 9%) but no TP53 mutations (0/22, 0%). Median overall survival (OS) was 59 months (vs. 19 months for IDHwt grade III gliomas (p< 0.0001). check details Twenty-nine patients (29/43, 67%) met the definition of molecular glioblastoma according to cIMPACT-NOW update3. Median OS in this subset was 42 months, which was shorter compared to patients with IDHwt grade II gliomas not meeting this definition (median OS 57 months), but substantially longer compared to IDHwt grade III gliomas meeting the definition for molecular glioblastoma (median OS 17 months, p<0.0001). Most patients with IDHwt grade II gliomas met cIMPACT criteria because of isolated TERT promoter mutations (16/26, 62%), which were not predictive of poor outcome (median OS 88 months). Actionable targets, including 5 gene fusions involving FGFR3, were found in 7 patients (24%).

Our findings highlight the importance of histological grading and molecular profiling for the prognostic stratification of IDHwt gliomas and suggest some caution when assimilating IDHwt grade II gliomas to molecular glioblastomas, especially those with isolated TERT promoter mutation.
