Wide-Antral Pulmonary Vein Isolation in Atrial Fibrillation Ablation with a Single-shot Technique (WIDER-PVI)

Ablation has become a first-line therapy in the rhythm control strategy for atrial fibrillation (AF). Pulmonary vein electrical isolation (PVI) is the cornerstone of ablation therapy, based on its efficacy profile, safety and lack of alternatives. Single shot techniques have been increasingly used as the initial approach for PVI, employing cryoablation, i.e. release of cryoenergy into the endocardium via an inflatable catheter, to achieve isolation. The most commonly used diameter in cryoablation is 28 mm. These generate antral isolation whose profile depends on the distance between veins. When the application is made with larger devices, as has been observed with the cryoballoon with an expandable diameter of 31 mm or ablation devices using pulsed electric fields, the isolation is also antral at the level of the carina, making the result of PVI more similar to that obtained when ablation is performed with a Wide Antral Circumferential Ablation (WACA) strategy using point-to-point radiofrequency (the gold standard for PVI). The WIDER-PVI study aims to answer the question of whether single-shot ablation with a 31 mm diameter device is superior to conventional ablation with a 28 mm diameter device. The answer to this question is relevant in the context of the development of new, larger devices and concerns about the impact of larger ablation on atrial function.

Multicenter Study Comparing AI-Based Navicam vs. Conventional Pillcam in Small Bowel Pathology

This is a prospective, multicenter, randomized, observational study involving multiple hospitals across Spain. At each site, patients will ingest both the Pillcam SB3 and Navicam capsules in a randomized order. Reading times, transit times, and diagnostic yield will be compared between the two devices. A central reading committee of experienced gastroenterologists will conduct blinded evaluations of both explorations using predefined criteria. The primary endpoint is the diagnostic concordance between Navicam's AI-driven ProScan™ system and the conventional reading of Pillcam SB3, measured by Cohen's kappa index. The secondary endpoints include to assess the correlation in lesion detection, video download times, gastric and small bowel transit times, total reading times, and adverse events. The sample size is 147 patients, accounting for an expected 10% dropout rate, based on previous studies showing a diagnostic concordance kappa index of 0.6. This study aims to establish that the AI-based Navicam capsule is at least as effective as the conventional Pillcam SB3 in diagnosing small bowel lesions, with potentially reduced reading times, thus enhancing clinical efficiency in small bowel diagnostics.

Registry of Patients in Shock Treated With Vasopressin

The main objective is to characterise the routine clinical practice of vasopressin use in the context of shock in a multicentre observational study. By collecting clinical, analytical and echocardiographic data in a uniform manner, describing the time sequence of vasopressin and/or noradrenaline use; how long vasopressin is used; and which vasoconstrictor is more frequently withdrawn earlier: vasopressin or noradrenaline. The secondary objectives are: - to assess what motivated the decision to initiate AVP: type of shock, perfusion parameters, noradrenaline dose; - to define the impact of initiating AVP on noradrenaline dose (whether the dose can be reduced or not), on cardiac function (whether echocardiographic data improve or worsen) and on perfusion data (whether laboratory and clinical data such as lactate, capillary refill time, mottling score or diuresis improve or worsen); - estimate what is the dose range of AVP used and what is the maximum dose used in routine clinical practice; - observe when AVP is stopped, how (abruptly or progressively); - describe the incidence of side effects of AVP, whether it is related to the dose of AVP and the comorbidities of the patients; - assess medium/long-term outcomes: 28- and 90-day mortality, ICU and hospital stay, days of vasopressor support, days of mechanical ventilation, days of renal replacement.

Immunological Characteristics of Preclinical IBD

This is a prospective, observational, multicenter, collaborative research project that will explore the earlier stages of IBD, before the onset of the first symptoms of the disease. This novel approach constitutes an innovative strategy on the research on the natural history of the disease. The study will be carried out based on colorectal cancer screening colonoscopies, recruiting all patients with a new diagnosis of IBD in this setting. These patients will undergo follow-up visits every 6 months for 10 years and the clinical information will be enriched with longitudinal multi-omic analyses. Two additional control groups will be identified, including patients with new-onset symptomatic IBD in the last 3 months and healthy controls (with normal screening colonoscopy).
