Disentangling the neural underpinnings of response inhibition in disruptive behavior and co-occurring ADHD.

While impaired response inhibition has been reported in attention-deficit/hyperactivity disorder (ADHD), findings in disruptive behavior disorders (DBDs) have been inconsistent, probably due to unaccounted effects of co-occurring ADHD in DBD. This study investigated the associations of behavioral and neural correlates of response inhibition with DBD and ADHD symptom severity, covarying for each other in a dimensional approach. Functional magnetic resonance imaging data were available for 35 children and adolescents with DBDs (8-18 years old, 19 males), and 31 age-matched unaffected controls (18 males) while performing a performance-adjusted stop-signal task.

Palmitate potentiates the SMAD3-PAI-1 pathway by reducing nuclear GDF15 levels.

Nuclear growth differentiation factor 15 (GDF15) reduces the binding of the mothers' against decapentaplegic homolog (SMAD) complex to its DNA-binding elements. However, the stimuli that control this process are unknown. Here, we examined whether saturated fatty acids (FA), particularly palmitate, regulate nuclear GDF15 levels and the activation of the SMAD3 pathway in human skeletal myotubes and mouse skeletal muscle, where most insulin-stimulated glucose use occurs in the whole organism.

Comparison of the amyloid plaque proteome in Down syndrome, early-onset Alzheimer's disease, and late-onset Alzheimer's disease.

Down syndrome (DS) is strongly associated with Alzheimer's disease (AD) due to APP overexpression, exhibiting Amyloid-β (Aβ) and Tau pathology similar to early-onset (EOAD) and late-onset AD (LOAD). We evaluated the Aβ plaque proteome of DS, EOAD, and LOAD using unbiased localized proteomics on post-mortem paraffin-embedded tissues from four cohorts (n = 20/group): DS (59.8 ± 4.

Inter-Rater Disagreements in Applying the Montreal Classification for Crohn's Disease: The Five-Nations Survey Study.

Background: The Montreal classification has been widely used in Crohn's disease since 2005 to categorize patients by the age of onset (A), disease location (L), behavior (B), and upper gastrointestinal tract and perianal involvement. With evolving management paradigms in Crohn's disease, we aimed to assess the performance of gastroenterologists in applying the Montreal classification.

Methods: An online survey was conducted among participants at an international educational conference on inflammatory bowel diseases.

Role of Cytokines in Predicting Early Major Bleeding in Patients With Acute Pulmonary Embolism.

Introduction: Anticoagulant therapy is critical for venous thromboembolism (VTE) management, though bleeding remains a major concern, ranging from mild to fatal events. This study aimed to assess the predictive value of cytokines for major bleeding in patients with acute pulmonary embolism (PE).

Methods: In this prospective, observational study, patients aged ≥ 18 years with acute PE were enrolled from April 2021 to September 2022 and followed for 30 days.

Gender inequalities in prescribing and initiation patterns of guideline-recommended drugs after acute myocardial infarction.

Background: European guidelines recommend the prescription of certain drugs after acute myocardial infarction (AMI). The existence of gender differences in pharmacological treatment after an AMI has been described. This study aims to describe and analyse, using real-world data (RWD), whether there are gender differences in the prescribing patterns and initiation of treatment in secondary prevention after a first AMI, and which are the factors that explain these differences.

Genomic reanalysis of a pan-European rare-disease resource yields new diagnoses.

Genetic diagnosis of rare diseases requires accurate identification and interpretation of genomic variants. Clinical and molecular scientists from 37 expert centers across Europe created the Solve-Rare Diseases Consortium (Solve-RD) resource, encompassing clinical, pedigree and genomic rare-disease data (94.5% exomes, 5.

Epicardial adipose tissue, cardiac damage, and mortality in patients undergoing TAVR for aortic stenosis.

Computed tomography (CT)-derived Epicardial Adipose Tissue (EAT) is linked to cardiovascular disease outcomes. However, its role in patients undergoing Transcatheter Aortic Valve Replacement (TAVR) and the interplay with aortic stenosis (AS) cardiac damage (CD) remains unexplored. We aim to investigate the relationship between EAT characteristics, AS CD, and all-cause mortality.

Development of the Crisis and Emergency Intervention Skills Scale (CEISS) and an analysis of its psychometric properties.

Emergency psychology is a branch of psychology that, although it began several years ago due to dramatic events around the world, is increasingly being established in the day-to-day work of the emergency department. Due to the very specific nature of this type of intervention, it is essential that, in addition to proper training and experience, emergency psychologists have a series of competencies. In this study, we developed a questionnaire, the Crisis and Emergency Intervention Skills Scale (CEISS), ad hoc for this research, and we determined the relationship of the CEISS score with the most relevant competencies.

Oxytocin levels in response to CRH administration in hypopituitarism and hypothalamic damage: a randomized, crossover, placebo-controlled trial.

Increasing evidence supports the presence of oxytocin deficiency (OXT-D) in patients with hypopituitarism and hypothalamic damage (HHD), that might be associated with neuropsychological deficits and sexual dysfunction, leading to worse quality of life (QoL). Therefore, identifying a provocative test to diagnose an OXT-D will be important. Corticotropin-releasing hormone (CRH) is a candidate for such a test as it increases oxytocin secretion in animal models.

Discordance, accuracy and reproducibility study of pathologists' diagnosis of melanoma and melanocytic tumors.

Accurate melanoma diagnosis is crucial for patient outcomes and reliability of AI diagnostic tools. We assess interrater variability among eight expert pathologists reviewing histopathological images and clinical metadata of 792 melanoma-suspicious lesions prospectively collected at eight German hospitals. Moreover, we provide access to the largest panel-validated dataset featuring dermoscopic and histopathological images with metadata.

Quantitative pre-clinical imaging of hypoxia and vascularity using MRI and PET.

During hypoxia, tissues are subjected to an inadequate oxygen supply, disrupting the balance needed to maintain normal function. This deficiency can occur due to reduced oxygen delivery caused by impaired blood flow or a decline in the blood's ability to carry oxygen. In tumors, hypoxia and vascularization play crucial roles, shaping their microenvironments and influencing cancer progression, response to treatment and metastatic potential.

Enhanced thermogenesis in PAS Kinase-deficient male mice.

PAS domain-containing serine/threonine-protein kinase (PASK) is a nutrient and energy sensor regulated by fasting/refeeding conditions in hypothalamic areas involved in controlling energy balance. In this sense, PASK plays a role in coordinating the activation/inactivation of AMP-activated protein kinase (AMPK) and mechanistic target of rapamycin (mTOR) in response to fasting. PASK deficiency protects against the development of diet-induced obesity.

Preclinical models of soft tissue sarcomas - generation and applications to enhance translational research.

Soft tissue sarcomas (STS) represent a large group of rare and ultra-rare tumors distinguished by unique morphological, molecular and clinical features. Patients with such rare cancers are generally underrepresented in clinical trials which has limited the introduction of new treatment options and subsequent improvement of patient outcomes. Preclinical models of STS that recapitulate the human disease can aid progress in identifying new effective treatments.

Midline venous catheter: New insights for its use in hospitalized patients with diabetes.

In a prospective study we found that in hospitalized patients with diabetes the use of mid line venous catheter (MVC) resulted in a significantly lower rate of vascular complications than short cannulas. However, a special attention should be paid to catheter obstruction when MCV is used.

Outcomes after medical treatment for primary aldosteronism: an international consensus and analysis of treatment response in an international cohort.

Background: Primary aldosteronism can be treated medically but there is no standardised method to evaluate treatment outcomes. We aimed to develop criteria for assessing the outcomes of targeted medical treatment of primary aldosteronism, analyse outcomes across an international cohort, and identify factors associated with a complete treatment response.

Methods: An international panel of 31 primary aldosteronism experts used the Delphi method to reach consensus on the definition of complete, partial, or absent biochemical and clinical outcomes of medical treatment of primary aldosteronism.

Discovery of a DNA methylation profile in individuals with Sifrim-Hitz-Weiss syndrome.

Pathogenic heterozygous variants in CHD4 cause Sifrim-Hitz-Weiss syndrome, a neurodevelopmental disorder associated with brain anomalies, heart defects, macrocephaly, hypogonadism, and additional features with variable expressivity. Most individuals have non-recurrent missense variants, complicating variant interpretation. A few were reported with truncating variants, and their role in disease is unclear.

First-in-human trial of atrial fibrillation ablation using real time tissue optical assessment to predict pulsed field lesion durability.

Background: Loss of bipolar electrograms immediately after pulsed field ablation (PFA) makes lesion durability assessment challenging.

Objective: The aim of this trial (NCT06700226) was to evaluate a novel ablation system that can optically predict lesion durability by detecting structural changes in the tissue during ablation.

Methods: Patients with paroxysmal atrial fibrillation underwent pulmonary vein isolation (PVI) using PFA (AblaView®, MedLumics).

Objectives: To assess the recurrence rate and quality of life (QOL) in women with a history of borderline ovarian tumours (BOTs) based on the type of surgery (conservative vs non-conservative) in Spain.

Study Design: A retrospective analysis was conducted of 85 women treated for BOTs between 2007 and 2023 at two hospitals. QOL questionnaires were administered face-to-face to eligible patients.

A comprehensive GPS-based analysis of activity spaces in early and late pregnancy using the ActMAP framework.

Health implications of mobility during pregnancy entail a need to understand pregnant women's activity spaces. We present ActMAP, a framework for quantifying multiple aspects of activity spaces from distinct trips and stays derived from GPS data. We applied ActMAP to data from 238 pregnant women in Barcelona, Spain (2018-2020) and explored weekday, weekend and intraday associations between pregnancy trimester and activity spaces.

Acute physical exercise and ambulatory blood pressure in resistant hypertension.

Objectives: The effects of acute physical exercise in patients with resistant hypertension remain largely unexplored compared with hypertensive patients in general. We assessed the short-term effects of acute moderate-intensity (MICE) and high-intensity interval exercise (HIIE) on the clinic (BP) and 24-h ambulatory blood pressure (ABP) of patients with resistant hypertension.

Methods: Using a crossover randomized controlled design, 10 participants (56 ± 7 years) with resistant hypertension performed three experimental sessions: MICE, HIIE, and control.

Efficacy and safety of finerenone in patients with chronic kidney disease and type 2 diabetes by diuretic use: A FIDELITY analysis.
