Combined left atrial appendage occlusion and catheter ablation for atrial fibrillation versus isolated left atrial appendage occlusion: A systematic review and meta-analysis.

Background: Data on the effects of combined left atrial appendage occlusion (LAAO) and catheter ablation (CA) for atrial fibrillation (AF) remain limited. We aimed to perform a systematic review and meta-analysis comparing LAAO and CA versus isolated LAAO.

Methods: We systematically searched PubMed, Embase, and Cochrane Library for studies comparing combined LAAO and CA versus isolated LAAO in patients with atrial fibrillation.

Genetic ancestry in Puerto Rican afro-descendants illustrates diverse histories of African diasporic populations.

Objectives: Genetic studies of contemporary Puerto Ricans reflect a demographic history characterized by admixture between Indigenous American, African, and European peoples. While previous studies provide genetic perspectives on the general Puerto Rican population, less is known about the island's sub-populations, specifically Afro-Puerto Ricans.

Materials And Methods: In this study, the genetic ancestry of Afro-Puerto Ricans is characterized and compared to other Caribbean populations.

The Eye of the Beholder: Attitudes toward divorced parents and perception of children's happiness in Peru and Spain.

Studies of divorce's effects on children have been oriented toward the parents' characteristics, ignoring their extended families. In the current study we collected data from 414 participants, both divorced parents and the children's extended families in Peru (155) and Spain (259). Participants completed a questionnaire on attitudes toward the parents, and the Short Dark Tetrad questionnaire.

Patients with Thyroid Dyshormonogenesis and Variants: Molecular and Clinical Description and Genotype-Phenotype Correlation.

Thyroid dyshormonogenesis (THD) is a heterogeneous group of genetic diseases caused by the total or partial defect in the synthesis or secretion of thyroid hormones. Genetic variants in can cause partial to total iodination organification defects and clinical heterogeneity, from transient to permanent congenital hypothyroidism. The aim of this study was to undertake a molecular characterization and genotype-phenotype correlation in patients with THD and candidate variants in .

Bio-Based Materials as a Sustainable Solution for the Remediation of Contaminated Marine Sediments: An LCA Case Study.

Contaminated sediments may induce long-term risks to humans and ecosystems due to the accumulation of priority and emerging inorganic and organic pollutants having toxic and bio-accumulation properties that could become a secondary pollution source. This study focused on the screening of novel bio-based materials to be used in the decontamination of marine sediments considering technical and environmental criteria. It aimed to compare the environmental impacts of cellulose-based adsorbents produced at lab scale by using different syntheses protocols that involved cellulose functionalization by oxidation and branching, followed by structuring of an aerogel-like material via Soxhlet extraction and freeze-drying or their combination.

Best practices for user consultation in flow cytometry shared resource laboratories.

This "Best Practices in User Consultation" article is the result of a 2022 International Society for the Advancement of Cytometry (ISAC) membership survey that collected valuable insights from the shared research laboratory (SRL) community and of a group discussion at the CYTO 2022 workshop of the same name. One key takeaway is the importance of initiating a consultation at the outset of a flow cytometry project, particularly for trainees. This approach enables the improvement and standardization of every step, from planning experiments to interpreting data.

Distal versus traditional radial access in patients undergoing emergency coronary angiography or percutaneous coronary intervention: a systematic review and meta-analysis.

Background: Distal radial access (DRA) is a well-tolerated and effective alternative to traditional radial access (TRA) for coronary procedures. However, the comparative value of these modalities remains unknown in the emergency setting, particularly in patients with ST-elevation myocardial infarction (STEMI).

Objective: To compare DRA versus TRA for emergency coronary procedures through a meta-analysis.

Torsemide versus Furosemide in the Treatment of Heart Failure: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Furosemide is the most used diuretic for volume overload symptoms in patients with heart failure (HF). Recent data suggested that torsemide may be superior to furosemide in this setting. However, whether this translates into better clinical outcomes in this population remains unclear.

Clinical and molecular study of patients with thyroid dyshormogenesis and variants in the gene.

Introduction: Defects in any thyroid hormone synthesis steps cause thyroid dyshormonogenesis (THD). THD due to () gene variants is a cause of congenital hypothyroidism (CH) with a wide clinical spectrum, ranging from mild to severe permanent hypothyroidism. We present high-throughput sequencing results of patients with variants.

Antibodies Against ZSCAN1 in Pediatric and Adult Patients With Non-Paraneoplastic ROHHAD Syndrome.

Objectives: To report the association of zinc finger and SCAN domain containing 1 antibodies (ZSCAN1-abs) with rapid-onset obesity, hypothalamic dysfunction, hypoventilation, and autonomic dysregulation (ROHHAD) syndrome in patients without tumor.

Methods: Patients with symptoms compatible with ROHHAD syndrome but without an associated tumor were selected from our database. Serum and CSF samples were examined for the presence of ZSCAN1-abs by an in-house cell-based assay.

Immunogenicity, safety and dual DIVA-like character of a recombinant candidate vaccine against neosporosis in cattle.

Neosporosis is the major infectious cause of abortion and reproductive losses in cattle worldwide; however, there are no available vaccines or drugs to control this disease. Recently, a dual (positive and negative) DIVA-like (Differentiation of Infected from Vaccinated Animals) vaccine was evaluated in a pregnant mouse model of neosporosis, showing promising immunogenic and protective results. The current report aimed to study the safety, the dose-dependent immunogenicity and the dual DIVA-like character of a recombinant subunit vaccine composed of the major surface antigen from Neospora caninum (rNcSAG1) and the carrier/adjuvant Heat shock protein 81.

Phase 3 Trial of Crinecerfont in Pediatric Congenital Adrenal Hyperplasia.

Background: Children with classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency require treatment with glucocorticoids, usually at supraphysiologic doses, to address cortisol insufficiency and reduce excess adrenal androgens. However, such treatment confers a predisposition to glucocorticoid-related complications. In 2-week phase 2 trials, patients with CAH who received crinecerfont, a new oral corticotropin-releasing factor type 1 receptor antagonist, had decreases in androstenedione levels.

Phosphate Uptake and Its Relation to Arsenic Toxicity in Lactobacilli.

The use of probiotic lactobacilli has been proposed as a strategy to mitigate damage associated with exposure to toxic metals. Their protective effect against cationic metal ions, such as those of mercury or lead, is believed to stem from their chelating and accumulating potential. However, their retention of anionic toxic metalloids, such as inorganic arsenic, is generally low.

Catheter ablation for atrial fibrillation in heart failure with reduced ejection fraction patients: A meta-analysis.

Background: The optimal treatment of atrial fibrillation (AF) in patients with heart failure with reduced ejection fraction (HFrEF) remains unsettled.

Objective: The purpose of this study was to assess the efficacy of catheter ablation (CA) and medical therapy compared to medical therapy alone in patients with AF and HFrEF.

Methods: We performed a systematic review of randomized controlled trials (RCTs) comparing CA with guideline-directed medical therapy for AF in patients with HFrEF (left ventricular ejection fraction [LVEF] ≤ 40%).

Chromosome-Y haplogroups in Asturias (Northern Spain) and their association with severe COVID-19.

The main objective of this study was to determine whether the common Y-haplogroups were be associated with the risk of developing severe COVID-19 in Spanish male. We studied 479 patients who required hospitalization due to COVID-19 and 285 population controls from the region of Asturias (northern Spain), They were genotyped for several polymorphisms that define the common European Y-haplogroups. We compared the frequencies between patients and controls aged ≤ 65 and >65 years.
