Background: Catheter ablation has obtained class 1 indication in ablation of young, healthy patients with symptomatic paroxysmal atrial fibrillation (AF). Anti-arrhythmic drugs (AADs) remain first-line therapy before ablating persistent AF (PersAF). We sought to evaluate the efficacy of a direct-to-catheter ablation approach against catheter ablation post AADs in PersAF.

Despite its effectiveness, significant sex-specific differences have been observed, which influence the outcomes of the procedure. This study explores these differences in a cohort of patients with persistent AF.

Aim: To study the relationships between food groups, diet quality and CRC risk, in an adult population of the Basque Country (North of Spain).
Methods: This observational study included 308 patients diagnosed with CRC and 308 age- and sex-matched subjects as controls.
Epidemiologic studies have revealed inconsistent evidence of gene-diet interaction in relation to colorectal cancer (CRC). The aim of this study was to analyze them in a sample of cases and controls from the population-based bowel cancer screening program of the Osakidetza/Basque Health Service. This study analyzed dietetic, genetic, demographic, socioeconomic factors and lifestyles.

We genotyped 230 CRC cases and 230 healthy controls for 48 previously reported CRC-susceptibility SNPs. Only the rs6687758 in DUPS10 exhibited a statistically significant association with CRC risk based on the crude analysis.

As it is a rare disease, its management in clinical practice remains largely unknown and heterogeneity of care remains a concern. The aim was to audit the management and evolution of a large series of low-grade gastric MALT lymphomas from thirteen Spanish hospitals.

It has been described that nematode larvae release venom allergen-like proteins among their excretion/secretion products.

The purpose of this study is to examine the TAS 24 and 72 h after glycerol injection in a model of myoglobinuric-ARF.
Experimental Design: The study was conduced in 28 Sprague-Dawley rats.
Oxygen metabolites play an important role in renal injury during myoglobinuric acute renal failure (ARF). This study was designed to determine the protective influence of N-acetylcysteine (NAC), a hydroxyl radical scavenger, and treatment in an experimental model of myoglobinuric-ARF induced by intramuscular injection of hypertonic glycerol in rats. The rats were randomly distributed into five groups: Group 0 (n = 10), was assigned to receive 2mL saline (0,9%) intraperitoneally (ip); Group 1 (n = 10), NAC ip in a dose of 0 mg/100 g of body weight 30 min before the intramuscular (im) injection of 50% glycerol (10 mg/kg); Group 2 (n = 10), received saline 0,9% ip in a equivalent volume of NAC in Group I before the im injection of glycerol; Group 3 (n = 10), received NAC ip in a dose of 10 mg/100 g after im injection of glycerol; Group 4 (n = 10), saline 0,9% ip in a equivalent volume of NAC of the Group 3 after im administration of glycerol.
