Effects of a video-feedback intervention on parenting behavior and state anxiety in mothers of children with neurodevelopmental disabilities.

Neurodevelopmental disability (ND) poses a significant challenge to infants' socio-emotional and cognitive development, as well as to caregiving dynamics, such as parental sensitivity and mother-infant interaction. Prior research highlights the crucial role of early parenting support interventions in enhancing parental behaviors, serving as a protective developmental factor for children at risk for or diagnosed with ND. This single-cohort, multicentric study aims to evaluate the efficacy of early video-feedback intervention (VFI) in improving maternal parenting behaviors.

Reproducible processing of TCGA regulatory networks.

Background: Technological advances in sequencing and computation have allowed deep exploration of the molecular basis of diseases. Biological networks have proven to be a useful framework for interrogating omics data and modeling regulatory gene and protein interactions. Large collaborative projects, such as The Cancer Genome Atlas (TCGA), have provided a rich resource for building and validating new computational methods resulting in a plethora of open-source software for downloading, pre-processing, and analyzing those data.

Higher-order correction of persistent batch effects in correlation networks.

Motivation: Systems biology analyses often use correlations in gene expression profiles to infer co-expression networks that are then used as input for gene regulatory network inference or to identify functional modules of co-expressed or putatively co-regulated genes. While systematic biases, including batch effects, are known to induce spurious associations and confound differential gene expression analyses (DE), the impact of batch effects on gene co-expression has not been fully explored. Methods have been developed to adjust expression values, ensuring conditional independence of mean and variance from batch or other covariates for each gene, resulting in improved fidelity of DE analysis.
