Ultraprocessed food intake and body mass index change among youths: a prospective cohort study.

Background: Suboptimal diets may promote undesired weight gain in youths, with high ultraprocessed food (UPF) intake becoming a significant concern in the United States.

Objectives: We evaluated the association between UPF intake and body mass index [BMI (in kg/m)] change in large United States youth cohorts.

Methods: Participants included children and adolescents (7-17 y) from the Growing Up Today Study (GUTS1 and GUTS2) who completed baseline and ≥1 follow-up diet and anthropometrics assessment (GUTS1 1996-2001: N = 15,797; GUTS2 2004-2011: N = 9720).

Combination of locoregional radiotherapy with a TIM-3 aptamer improves survival in diffuse midline glioma models.

Pediatric diffuse midline gliomas (DMG) with altered H3-K27M are aggressive brain tumors that arise during childhood. Despite advances in genomic knowledge and the significant number of clinical trials testing new targeted therapies, patient outcomes are still poor. Immune checkpoint blockades with small molecules, such as aptamers, are opening new therapeutic options that represent hope for this orphan disease.

Identification of a pathogenic mutation in in patients with amyotrophic lateral sclerosis.

Background And Objective: Between 5% and 10% of amyotrophic lateral sclerosis (ALS) cases have a family history of the disease, 30% of which do not have an identifiable underlying genetic cause after a comprehensive study of the known ALS-related genes. Based on a significantly increased incidence of ALS in a small geographical region from Spain, the aim of this work was to identify novel ALS-related genes in ALS cases with negative genetic testing.

Methods: We detected an increased incidence of both sporadic and, especially, familial ALS cases in a small region from Spain compared with available demographic and epidemiological data.

Gliomatosis cerebri in children: A poor prognostic phenotype of diffuse gliomas with a distinct molecular profile.

Background: The term gliomatosis cerebri (GC), a radiology-defined highly infiltrating diffuse glioma, has been abandoned since molecular GC-associated features could not be established.

Methods: We conducted a multinational retrospective study of 104 children and adolescents with GC providing comprehensive clinical and (epi-)genetic characterization.

Results: Median overall survival (OS) was 15.

The heterogeneous sensitivity of pediatric brain tumors to different oncolytic viruses is predicted by unique gene expression profiles.

Despite decades of research, the prognosis of high-grade pediatric brain tumors (PBTs) remains dismal; however, recent cases of favorable clinical responses were documented in clinical trials using oncolytic viruses (OVs). In the current study, we employed four different species of OVs: adenovirus Delta24-RGD, herpes simplex virus rQNestin34.5v1, reovirus R124, and the non-virulent Newcastle disease virus rNDV-F0-GFP against three entities of PBTs (high-grade gliomas, atypical teratoid/rhabdoid tumors, and ependymomas) to determine their efficacy.

Development of a Short Version of the ADHD Rating Scale-IV.es (sADHD-RS-IV.es).

Objective: To develop a short version of the Spanish 18-item ADHD-Rating Scale IV.es (sADHD-RS-IV.es) to be used as a potential screening tool in pediatric population.

Meeting muscle-strengthening recommendation is associated with lower adiposity, higher physical fitness and healthier lifestyle in adolescents: The EHDLA study.

Aim: To determine the prevalence of adolescents who meet muscle-strengthening activities (MSA) recommendation and their associations with anthropometric variables, physical fitness, and lifestyle behaviours in a sample of Spanish adolescents aged 12-17 years.

Methods: This was a cross-sectional study using data from The Eating Healthy and Daily Life Activities (EHDLA) Study. Participants reported the days on which they engaged in MSA (≥3 days per week were considered to meet World Health Organization recommendation).

Characterization of immune populations in the tumor microenvironment of diffuse midline glioma orthotopic mouse models by flow cytometry.

The immune response is a fundamental process in the treatment of solid tumors. Here, we present a protocol for implanting diffuse midline glioma cells in the brain of immune-competent mice and characterizing the different immune populations in the tumor microenvironment in a flow cytometry panel. We describe steps for processing of brain tumors, isolating the immune cells, and subsequent staining with antibodies for flow cytometry.

Promises of oncolytic viral therapy for adult and children with brain glioma.

Purpose Of Review: The purpose of this review is to give an overview of early clinical studies addressing the safety and efficacy of oncolytic immunovirotherapy in adults and children with brain gliomas, and to highlight the extensive potential for the development of this therapeutic alternative.

Recent Findings: The lack of curative treatments and poor prognosis of high-grade glioma patients warrants research on innovative therapeutic alternatives such as oncolytic immunovirotherapy. Engineered modified oncolytic viruses exert both a direct lytic effect on tumor cells and a specific antitumor immune response.

A deep learning image analysis method for renal perfusion estimation in pseudo-continuous arterial spin labelling MRI.

Accurate segmentation of renal tissues is an essential step for renal perfusion estimation and postoperative assessment of the allograft. Images are usually manually labeled, which is tedious and prone to human error. We present an image analysis method for the automatic estimation of renal perfusion based on perfusion magnetic resonance imaging.

Clinical Efficacy of ONC201 in H3K27M-Mutant Diffuse Midline Gliomas Is Driven by Disruption of Integrated Metabolic and Epigenetic Pathways.

Unlabelled: Patients with H3K27M-mutant diffuse midline glioma (DMG) have no proven effective therapies. ONC201 has recently demonstrated efficacy in these patients, but the mechanism behind this finding remains unknown. We assessed clinical outcomes, tumor sequencing, and tissue/cerebrospinal fluid (CSF) correlate samples from patients treated in two completed multisite clinical studies.

Oncolytic viruses as treatment for adult and pediatric high-grade gliomas: On the way to clinical success.

High-grade gliomas (HGGs) are the most common and aggressive primary brain tumors in both adult and pediatric populations. Despite the multimodal treatment modality currently available for HGG, the prognosis is dismal, with a low overall survival rate at two years after diagnosis. In the last decade, oncolytic virotherapy has emerged as a promising and feasible therapeutic tool in management of these tumors due to its oncolytic and immunostimulatory properties.

Objectives: The aim of this study was to develop and validate a feasible prediction model and score to facilitate the diagnosis of ATTR-CA.

Methods: This retrospective multicenter study enrolled consecutive patients who underwent Tc-DPD scintigraphy for suspected ATTR-CA.

Determinants and impact of splanchnic vein thrombosis in acute pancreatitis.

Background: Splanchnic vein thrombosis (SVT) is a well-recognised though little-studied complication in acute pancreatitis (AP). SVT risk factors, its clinical consequences and the role of anticoagulation (AC) therapy is scarce.

Aims: To evaluate the incidence and natural history of SVT in AP.

Local treatment in oligometastasis from breast cancer: an overview.

Oligometastasic breast cancer (OMBC) consists of breast cancer patient with a limited number of systemic metastases (≤ 5), all of them candidates for local ablative treatment with the intention of achieving long-term control of the metastasis and, eventually, an increase in survival The first consensus for the management of patients with oligometastatic breast cancer (OMBC) was published in 2007, establishing that a more aggressive multidisciplinary strategy is recommended in order to increase the survival while maintaining a good quality of life. The current scientific evidence is based on observational studies, mainly retrospective, systematic reviews and meta-analyses, and only a randomized nonexclusive study of oligometastatic (OM) published. All trials with Stereotactic Body Radiation Therapy (SBRT) in OM cancer have shown excellent tolerance and good local control, although first trials on Lung SBRT did not prove so excellent tolerance and had some deaths due to bronchus irradiation and secondary hemoptysis.

Oncolytic virotherapy for the treatment of pediatric brainstem gliomas.

Diffuse intrinsic pontine glioma (DIPG) is the most frequent brainstem glioma and the most lethal brain tumor in childhood. Despite transient benefit with radiotherapy, the prognosis of children with this disease remains dismal with severe neurological morbidity and median survival less than 12months. Oncolytic immunovirotherapy is emerging as a potential therapeutic approach in neuro-oncology.

What is the role of adherence to 24-hour movement guidelines in relation to physical fitness components among adolescents?

Background: Physical inactivity, excessive sedentary time, and lack of sleep time have been independently associated with lower health-related physical fitness. However, little is known about the combined association between 24-h movement guidelines (i.e.

Targeted siRNA lipid nanoparticles for the treatment of KRAS-mutant tumors.

K-RAS is a highly relevant oncogene that is mutated in approximately 90% of pancreatic cancers and 20-25% of lung adenocarcinomas. The aim of this work was to develop a new anti-KRAS siRNA therapeutic strategy through the engineering of functionalized lipid nanoparticles (LNPs). To do this, first, a potent pan anti-KRAS siRNA sequence was chosen from the literature and different chemical modifications of siRNA were tested for their transfection efficacy (KRAS knockdown) and anti-proliferative effects on various cancer cell lines.
