Successful ablation of Purkinje-related ventricular ectopy leading to ventricular fibrillation in Emery-Dreifuss dilated cardiomyopathy.

Introduction: Mutations in EMD are related to an increased risk of ventricular arrhythmias and sudden cardiac death. There is a lack of data concerning ventricular arrhythmia ablation in Emery-Dreifuss patients.

Methods And Results: We present a case of successful ablation of a short-coupled ventricular ectopy (VE) triggering recurrent ventricular fibrillation (VF) episodes in a EMD patient with an intraseptal substrate.

Temperament Characteristics of Children in Residential Care and Perceived Acceptance/Rejection and Style of Discipline Used by Care Workers.

The ability to adapt interpersonal interactions to temperamental characteristics is essential for high-quality care. We analyzed how temperamental and self-regulation differences among children in residential care were related to the affective relationships and discipline styles of their caregivers. A total of 144 children aged 9-16 years (42.

Antibiotic-associated neutropenia is marked by the depletion of intestinal and associated metabolites in pediatric patients.

Prolonged antibiotic exposure causes dangerous hematologic side effects, including neutropenia, in up to 34% of patients. Murine studies established a link between the intestinal microbiota and hematopoiesis. To identify factors that predispose to neutropenia in pediatric patients, we evaluated changes in microbiota-derived metabolites and intestinal microbiota composition after prolonged courses of antibiotics.

Mix and measure II: joint high-energy laboratory powder diffraction and microtomography for cement hydration studies.

Portland cements (PCs) and cement blends are multiphase materials of different fineness, and quantitatively analysing their hydration pathways is very challenging. The dissolution (hydration) of the initial crystalline and amorphous phases must be determined, as well as the formation of labile (such as ettringite), reactive (such as portlandite) and amorphous (such as calcium silicate hydrate gel) components. The microstructural changes with hydration time must also be mapped out.

Standardizing the evaluation and management of iron deficiency anemia secondary to heavy menstrual bleeding in the emergency department.

Background: Comprehensive guidelines for the management of iron deficiency anemia (IDA) in adolescents with heavy menstrual bleeding (HMB) presenting to the emergency department (ED) are lacking, leading to variability in care. We aimed to standardize the evaluation and management of these patients through the development and implementation of an evidence-based algorithm using quality improvement methodology.

Methods: Baseline data of the target population identified variability across four key measures of clinical management: therapy choice and administration, laboratory evaluation, hematology service consultation, and patient disposition.

Effects of exercise on life satisfaction of people diagnosed with cancer: a systematic review and meta-analysis.

Purpose: A cancer diagnosis is commonly associated with a decline in patient's life satisfaction and more pessimistic expectations about the future. The identification of strategies to improve life satisfaction in patients with cancer is of great interest to health practitioners since it may be associated with a better prognosis of cancer and higher survival rates. Previous meta-analyses and reviews concluded that exercise could significantly improve health-related quality of life in this population, but the effects of exercise on life satisfaction are still not well-known.

Timing of coronary angiography and use of antiplatelet pretreatment in patients with NSTEACS in Spain.

Introduction And Objectives: The optimal timing of coronary angiography in patients admitted with non-ST-segment elevation acute coronary syndrome (NSTEACS) as well as the need for pretreatment are controversial. The main objective of the IMPACT-TIMING-GO registry was to assess the proportion of patients undergoing an early invasive strategy (0-24hours) without dual antiplatelet therapy (no pretreatment strategy) in Spain.

Methods: This observational, prospective, and multicenter study included consecutive patients with NSTEACS who underwent coronary angiography that identified a culprit lesion.

Effects of Caffeinated Coffee on Cross-Country Cycling Performance in Recreational Cyclists.

The ergogenic effects of acute caffeine intake on endurance cycling performance lasting ~1 h have been well documented in controlled laboratory studies. However, the potential benefits of caffeine supplementation in cycling disciplines such as cross-country/mountain biking have been rarely studied. In cross-country cycling, performance is dependent on endurance capacity, which may be enhanced by caffeine, but also on the technical ability of the cyclist to overcome the obstacles of the course.

Effect of Acute Caffeine Intake on Fat Oxidation Rate during Fed-State Exercise: A Systematic Review and Meta-Analysis.

Pre-exercise intake of caffeine (from ~3 to 9 mg/kg) has been demonstrated as an effective supplementation strategy to increase fat oxidation during fasted exercise. However, a pre-exercise meal can alter the potential effect of caffeine on fat oxidation during exercise as caffeine modifies postprandial glycaemic and insulinemic responses. Hypothetically, the effect of caffeine on fat oxidation may be reduced or even withdrawn during fed-state exercise.

Designing Weights for Quartet-Based Methods When Data are Heterogeneous Across Lineages.

Homogeneity across lineages is a general assumption in phylogenetics according to which nucleotide substitution rates are common to all lineages. Many phylogenetic methods relax this hypothesis but keep a simple enough model to make the process of sequence evolution more tractable. On the other hand, dealing successfully with the general case (heterogeneity of rates across lineages) is one of the key features of phylogenetic reconstruction methods based on algebraic tools.

Sensitisation to Pollen Allergens in Children and Adolescents of Different Ancestry Born and Living in the Same Area.

Background: Allergy can start at early ages, with genetic and environmental factors contributing to its development.

Aim: The study aimed to describe the pattern of sensitisation and allergy in children and adolescents of Spanish versus Moroccan ancestry but born in the same rural area of Spain.

Methods: Participants were children and adolescents (3-19 years) of Spanish or Moroccan descent, born in Blanca, Murcia (Spain).

Luminescent Citrate-Functionalized Terbium-Substituted Carbonated Apatite Nanomaterials: Structural Aspects, Sensitized Luminescence, Cytocompatibility, and Cell Uptake Imaging.

This work explores the preparation of luminescent and biomimetic Tb-doped citrate-functionalized carbonated apatite nanoparticles. These nanoparticles were synthesized employing a citrate-based thermal decomplexing precipitation method, testing a nominal Tb doping concentration between 0.001 M to 0.

Converter Phenotype: A New Profile That Is Not Exclusive to Taxanes.

Phenotype I hypersensitivity reactions are the most commonly reported drug reactions; however, precision medicine has made it possible to characterize new phenotypes. A recent communication proposed the existence of a "converter phenotype," which would affect patients who present non-immediate hypersensitivity reactions and in subsequent exposures develop immediate hypersensitivity reactions. This study aimed to describe the clinical characteristics of converter phenotype reactions and their evolution during desensitization to chemotherapeutic drugs and monoclonal antibodies.

Biomimetic Citrate-Coated Luminescent Apatite Nanoplatforms for Diclofenac Delivery in Inflammatory Environments.

Luminescent nanoparticles are innovative tools for medicine, allowing the imaging of cells and tissues, and, at the same time, carrying and releasing different types of molecules. We explored and compared the loading/release ability of diclofenac (COX-2 antagonist), in both undoped- and luminescent Terbium (Tb)-doped citrate-coated carbonated apatite nanoparticles at different temperatures (25, 37, 40 °C) and pHs (7.4, 5.
