further exploration for children with MB to be considered for late-effect sparing approaches.
Reducing the radiation boost volume in average-risk MB is safe and does not compromise survival. Reducing CSI dose in young children with average-risk MB results in inferior outcomes, possibly in a subgroup-dependent manner, but is associated with better neurocognitive outcome. Molecularly informed patient selection warrants further exploration for children with MB to be considered for late-effect sparing approaches.Aim Plasma and serum are widely used blood-derived biofluids for metabolomics and lipidomics assays, but analytes that are present in high concentrations in blood cells cannot be evaluated in those samples and isolating serum or plasma could introduce additional variability in the data. Materials & methods In this study, we provide a comprehensive method for quantification of the whole blood (WB) sphingolipidome, combining a single-phase extraction method with LC-high-resolution mass spectrometry. Results We were able to quantify more than 150 sphingolipids, and when compared with paired plasma, WB contained higher concentration of most sphingolipids and individual variations were lower. These findings suggest that WB could be a better alternative to plasma, and potentially guide the evaluation of the sphingolipidome for biomarker discovery.
Clinical outcomes of patients with neuroblastoma range from spontaneous tumor regression to fatality. UGT8-IN-1 Hence, understanding the mechanisms that cause tumor progression is crucial for the treatment of patients. In this study, we show that
activation identifies a subset of neuroblastoma tumors with unfavorable outcome and we investigate the mechanism how FOXR2 relates to poor outcome in patients.

We analyzed three independent transcriptional data sets of in total 1030 primary neuroblastomas with full clinical annotation. We performed immunoprecipitation for FOXR2 and MYCN and silenced FOXR2 expression in two neuroblastoma cell lines to examine the effect on cellular processes, transcriptome, and MYCN protein levels. Tumor samples were analyzed for protein levels of FOXR2 and MYCN.

In three combined neuroblastoma data sets, 9% of tumors show expression of
but have low levels of
mRNA.
expression identifies a group of patients with unfavorable outcome, showing 10-year overall survival rates of 53%OXR2 expression identifies another subset of neuroblastoma patients with unfavorable clinical outcome.Although stress due to racial and ethnic differences can negatively impact life satisfaction, there is a lack of focus on the differences between minority and nonminority older adults in how stress and coping skills impact life satisfaction. The objectives of this study are to explore (a) the differences between minority and nonminority older adults in their levels of life satisfaction, stress, and coping skills; and (b) the mediating effects of coping skills on the relationship between perceived stress and life satisfaction among both groups. Cross-sectional data from the Well Elderly 2 study (N = 460) were utilized in bivariate and mediation analyses. Minority older adults reported higher levels of stress and prioritized different coping skills. Mediation was not supported for either group. These findings enable practitioners to focus on the coping skills more frequently identified by clients' racial/ethnic grouping, as well as to target the primary stressors identified.Objectives. To examine homicide rates in Cali, Colombia, during the 1993-2018 period, using information derived from an interagency surveillance system. Methods. We used homicide data from Cali's Epidemiological Surveillance System to examine homicide trends by victim's age and sex, time, and type of method used. We estimated trend changes and the annual percentage changes using joinpoint regression analyses. Results. Homicide rates per 100 000 inhabitants dropped from 102 in 1993 to 47.8 in 2018. We observed reductions in homicide rates across age and sex groups. Most homicide victims were men aged 20 to 39 years from poor, marginalized areas. Firearms were used in 84.9% of all cases. The average annual percentage change for the entire period was -3.6 (95% confidence interval = -6.7, -0.4). Conclusions. Fluctuations in homicide rates in Cali show a clear epidemic pattern, occurring concurrently with the "crack epidemic" in different countries. Reliable and timely information provided by an Epidemiological Surveillance System allowed opportune formulation of public policies to reduce the impact of violence in Cali.Objectives. To explore whether beneficial health care policies, when implemented in the context of gender inequality, yield unintended structural consequences that stigmatize and ostracize women with HIV from "what matters most" in local culture. Methods. We conducted 46 in-depth interviews and 5 focus groups (38 individuals) with men and women living with and without HIV in Gaborone, Botswana, in 2017. Results. Cultural imperatives to bear children bring pregnant women into contact with free antenatal services including routine HIV testing, where their HIV status is discovered before their male partners'. National HIV policies have therefore unintentionally reinforced disadvantage among women with HIV, whereby men delay or avoid testing by using their partner's status as a proxy for their own, thus facilitating blame toward women diagnosed with HIV. Gossip then defines these women as "promiscuous" and as violating the essence of womanhood. We identified cultural and structural ways to resist stigma for these women. Conclusions. Necessary HIV testing during antenatal care has inadvertently perpetuated a structural vulnerability that propagates stigma toward women. Individual- and structural-level interventions can address stigma unintentionally reinforced by health care policies.Peripheral artery disease is an atherosclerotic disorder which, when present, portends poor patient outcomes. Low diagnosis rates perpetuate poor management, leading to limb loss and excess rates of cardiovascular morbidity and death. Machine learning algorithms and artificially intelligent systems have shown great promise in application to many areas in health care, such as accurately detecting disease, predicting patient outcomes, and automating image interpretation. Although the application of these technologies to peripheral artery disease are in their infancy, their promises are tremendous. In this review, we provide an introduction to important concepts in the fields of machine learning and artificial intelligence, detail the current state of how these technologies have been applied to peripheral artery disease, and discuss potential areas for future care enhancement with advanced analytics.
