RAS pathway mutations as a predictive biomarker for treatment adaptation in pediatric B-cell precursor acute lymphoblastic leukemia
RAS pathway mutations have been linked to relapse and chemotherapy resistance in pediatric B-cell precursor acute lymphoblastic leukemia (BCP-ALL). However, comprehensive data on the frequency and prognostic value of subclonal mutations in well-defined subgroups using highly sensitive and quantitative methods are lacking. Targeted deep sequencing of 13 RAS pathway genes was performed in 461 pediatric BCP-ALL cases at initial diagnosis and in 19 diagnos

Impact of comorbid conditions on asthmatic adults and children
Comorbid conditions (comorbidities) can complicate the diagnosis and management of asthma. In different age groups, comorbid conditions can present varying challenges, including diagnostic confusion due to mimicking asthma symptoms, exacerbation of asthma symptoms, therapy for comorbid conditions affecting asthma or therapy for asthma affecting these conditions. This review aims to summarise some common comorbid conditions with asthma, such as rhinitis, vocal cord dysfunction, gastro-oesophageal reflux, psychiatric disorders, obesity and obstructive sleep apnoea, and discuss their prevalence, symptoms, diagnosis and treatment, highlighting any differences in how they impact children and adults. Overall, there is a lack of data on the impact of treating comorbid conditions on asthma outcomes and further studies are needed to guide age-appropriate asthma management in the presence of these conditions.This article is freely available via Open Access.

On extremal dependence : some contributions
The usual coefficients of tail dependence are based on exceedances of high
values. These extremal events are useful and widely used in literature but an adverse
situation may also occur with the upcrossing of a high level. In this context we define
upcrossings-tail dependence coefficients and analyze all types of dependence coming
out. We will prove that these coefficients are related to multivariate tail dependence
coefficients already known in literature. We shall see that the upcrossings-tail dependence
coefficients have the interesting feature of congregating both “temporal” and
“spatial” dependence.
The coefficients of tail dependence can also be applied to stationary sequences and
hence measure the tail dependence in time. Results concerning connections with the
extremal index and the upcrossings index as well as with local dependence conditions
will be stated. Several illustrative examples will be exploited and a small note on
inference will be given by presenting estimators derived from the stated results and
respective properties.Fundação para a Ciência e a Tecnologia (FCT
Extremes of multivariate ARMAX processes
We define a new multivariate time series model by generalizing the ARMAX
process in a multivariate way. We give conditions on stationarity and analyze
local dependence and domains of attraction. As a consequence of the obtained results,
we derive new multivariate extreme value distributions.We characterize the extremal
dependence by computing the multivariate extremal index and bivariate upper tail dependence
coefficients. An estimation procedure for the multivariate extremal index is
presented. We also address the marginal estimation and propose a new estimator for
the ARMAX autoregressive parameter.Fundação para a Ciência e a Tecnologia (FCT
