Evaluating the Genetic Overlap Between Congenital Heart Disease and Neuroblastoma Risk

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Children with congenital heart disease (CHD) have elevated neuroblastoma (NB) risk, potentially due to shared neural crest origins. We analyzed rare exonic de novo single‐nucleotide variants in 702 CHD and 454 NB trios from the Neuroblastoma Epidemiology in North America Study, Gabriella Miller Kids First Program, and a published cohort. Seven

Asymptotic distributions of degenerated U-statistics

Statistical Theory and Related Fields
A degenerated U-statistic with rank 2 is known to converge in distribution to a weighted sum of independent chi-square random variables. However, a result for the asymptotic distribution of a degenerated U-statistic with rank higher than 2 is not ...

On a Less Cumbersome Method of Estimation of Parameters of Type III Generalized Logistic Distribution by Order Statistics

Statistica, 2015
In this work we have derived appropriate U-statistics from a sample of any size exceeding a specified integer to estimate the location and scale parameters of Type III generalized logistic distribution without the knowledge or by evaluation of the means,

Clinical Correlates of Anxiety and Depression After Diagnosis of a Pediatric Brain Tumor

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background The prevalence and clinical correlates of symptoms of anxiety and depression in pediatric patients with brain tumors are not well described. We aimed to identify clinical characteristics that are correlated with elevated symptoms of anxiety and depression following initial diagnosis.

Preoperative Cytopenia in Patients Affected by High‐Risk Neuroblastoma: Just a Matter of Platelets?

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims In patients affected by high‐risk neuroblastoma (HR‐NB), complete macroscopic resection (CMR) is associated with better outcomes. These patients are often cytopenic due to intensive induction regimens. The aim of the present study is to assess the impact of preoperative cytopenia on surgical outcome in patients with HR‐NB ...

DELP Treatment on Vision and Retinal Microcirculation in Patients With Acute Ischemic Stroke: Report of Five Cases and Literature Review

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background The delipid extracorporeal lipoprotein filter from plasma (DELP) treatment can effectively reduce blood lipid, increase blood flow, and improve neurological deficits in patients with acute ischemic stroke (AIS). However, its effect on vision and retinal microcirculation in stroke patients has never been reported.

New Algorithms for $M$-Estimation of Multivariate Scatter and Location [PDF]

, 2015
We present new algorithms for $M$-estimators of multivariate scatter and location and for symmetrized $M$-estimators of multivariate scatter. The new algorithms are considerably faster than currently used fixed-point and related algorithms. The main idea

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Limit theorems for nonparametric conditional U-statistics smoothed by asymmetric kernels

AIMS Mathematics
$ U $-statistics represent a fundamental class of statistics used to model quantities derived from responses of multiple subjects. These statistics extend the concept of the empirical mean of a $ d $-variate random variable $ X $ by considering sums over

Approximations for multivariate U-statistics

Journal of Multivariate Analysis, 1987
Let \(X_ 1,X_ 2,..\). be independent, identically distributed random variables with values in a measurable space (\({\mathcal X},{\mathcal F})\) and let \(H: {\mathcal X}\times {\mathcal X}\to {\mathbb{R}}^ k\) be measurable and symmetric. The author derives a Berry-Esseen type approximation and an Edgeworth expansion of order up to \(o(N^{-})\) of the
