Artificial intelligence-adjudicated spatiotemporal dispersion: A patient-unique fingerprint of persistent atrial fibrillation.

Background: Spatiotemporal dispersion-guided ablation is a tailored approach for patients in persistent atrial fibrillation (PsAF). The characterization of dispersion extent and distribution and its association with common clinical descriptors of PsAF patients has not been studied.

Objectives: Artificial intelligence-adjudicated dispersion extent and distribution (AI-DED) was obtained with a machine/deep learning classifier (VX1 Software, Volta Medical) in PsAF patients undergoing ablation.

Artificial intelligence software standardizes electrogram-based ablation outcome for persistent atrial fibrillation.

Introduction: Multiple groups have reported on the usefulness of ablating in atrial regions exhibiting abnormal electrograms during atrial fibrillation (AF). Still, previous studies have suggested that ablation outcomes are highly operator- and center-dependent. This study sought to evaluate a novel machine learning software algorithm named VX1 (Volta Medical), trained to adjudicate multipolar electrogram dispersion.

The novelties of the regulation on health technology assessment, a key achievement for the European union health policies.

Health technology assessment is a key tool for ensuring healthcare quality, accessibility, and sustainability. The novel European Union (EU) Health Technology Assessment (HTA) regulation of 15 December 2021, in harmonizing the laws of the Member States about the procedures and criteria for the evaluation of health technologies (i.e.

Preoperative diagnosis and surgical treatment for giant retroperitoneal liposarcoma: A case report.

Introduction: The purpose of this article is to present the diagnostic and surgical approach for a giant retroperitoneal sarcoma and to highlight the difficulty of a precise preoperative diagnosis and the extention of surgical resection.

Presentation Of Case: A 63-year-old female patient was admitted at our department with light diffuse abdominal pain, fever and gradual increase of abdominal girth. A CT scan showed a giant fatty tumor occupying left hemiabdomen and indirect findings of renal damage, probably sustained by ureter stretching and urine stasis.

The effectiveness of Hemopatch™ in preventing postoperative distal pancreatectomy fistulas.

Objectives: Postoperative fistula after distal pancreatectomy (DP) is still a significant complication, although many tools and tips have been utilized to try to reduce its elevated frequency. This paper focuses on the role of a sealing hemostatic device, Hemopatch™, to prevent postoperative pancreatic fistula (POPF) after DP.

Methods: Retrospectively we divided our sampling of 57 patients submitted to DP into two groups according to the availability of the device: 18 patients without Hemopatch™ and 39 patients using Hemopatch™.

Correction to: Acute acalculous cholecystitis determining Mirizzi syndrome: case report and literature review.

Following publication of the original article [1], the authors reported that one of the authors' names is spelled incorrectly.

AF Ablation Guided by Spatiotemporal Electrogram Dispersion Without Pulmonary Vein Isolation: A Wholly Patient-Tailored Approach.

Background: The use of intracardiac electrograms to guide atrial fibrillation (AF) ablation has yielded conflicting results.

Objectives: The authors evaluated the usefulness of spatiotemporal dispersion, a visually recognizable electric footprint of AF drivers, for the ablation of all forms of AF.

Methods: The authors prospectively enrolled 105 patients admitted for AF ablation.

Electrogram Fractionation-Guided Ablation in the Left Atrium Decreases the Frequency of Activation in the Pulmonary Veins and Leads to Atrial Fibrillation Termination: Pulmonary Vein Modulation Rather Than Isolation.

Objectives: This study sought to evaluate the impact of a complex fractionated atrial electrogram (CFAE)-guided ablation strategy on atrial fibrillation (AF) dynamics in patients with persistent AF.

Background: It is still unclear whether complete pulmonary vein isolation (PVI) is required or if the ablation of well-delineated pulmonary vein (PV) subregions could achieve similar outcomes in persistent AF.

Methods: CFAE-guided ablations were performed in 76 patients (65.

Acute acalculous cholecystitis determining Mirizzi syndrome: case report and literature review.

Background: Although Mirizzi syndrome is widely reported in literature, little is known about acute acalcholous cholecystitis determinig the findings of a Mirizzi syndrome.

Case Presentation: We report a case of MRCP-confirmed Mirizzi syndrome in acute acalculous cholecystitis resolved by surgery.

Conclusion: Acute acalcholosus cholecystitis determinig a Mirizzi Syndrome should be included in the Mirizzi classification as a type 1.

Bariatric surgery is not contraindicated in obese patients suffering from glycogen storage disease type IXa. A case report with follow-up at three years.

Introduction: Glucose storage disease type IXa (GSD IXa) is an uncommon condition presenting with childhood onset hepatomegaly, growth retardation, and often, fasting ketosis and hypoglycemia. Despite its benign course, the lack of dietary counseling may favor uncontrolled weight gain. We investigated the efficacy of bariatric surgery in one 17 years old female suffering from GSD IXa and morbid obesity.

Bariatric surgery in elderly patients. A comparison between gastric banding and sleeve gastrectomy with five years of follow up.

Introduction: The prevalence of obesity is rising progressively, even among elderly patients. Many studies investigated about safety and efficacy of bariatric surgery among aged obese patients. The objective of this review is to assess the benefits relative to risks of weight loss that may be obtained by performing two common bariatric procedures in obese elderly patient.

Laparoscopic sleeve gastrectomy: efficacy of fibrin sealant in reducing postoperative bleeding. A randomized controlled trial.

Staple line leakage and bleeding are worrisome complications of laparoscopic sleeve gastrectomy (LSG). Solutions such as buttressing, oversewing or roofing the staple line with gelatin matrix have been proposed with controversial results. Because the use of fibrin sealant has shown a possible benefit in reducing the reoperation rate due to early complication in patients (pts) undergoing laparoscopic Roux-en-Y gastric bypass (LRYGBP), this solution has been tested in 100 consecutive pts undergoing LSG.

An early onset of acute renal failure in a young woman with obesity and infertility who underwent gastric balloon positioning. A case report.

Introduction: Although intragastric balloons have been in use for several years to achieve weight reduction in obese patients, acute renal failure after gastric balloon positioning is reported in few studies

Case Report: A 32-year-old white infertile woman undergone Bioenterics Intragastric Balloon (BIB) positioning in an attempt to weight loss and improve her fertility status. After only six days of persisting vomiting acute renal failure was found. A complete recovery of renal function was obtained after 14 days.

Wernicke encephalopathy in subjects undergoing restrictive weight loss surgery: a systematic review of literature data.

The use of weight loss surgery is progressively increasing, and in recent years, restrictive bariatric surgery procedures have been more often used. Although thought to be associated with a lower incidence of post-operative side effects than malabsorpitive surgery, some cases of micronutrients deficiency have been reported because of an acquired thiamine deficiency; in this clinical setting, some cases of Wernicke encephalopathy (WE) have been described. Major determinants and predictors of this major neurological complication are currently unknown.

Active or passive pulmonary vein in atrial fibrillation: is pulmonary vein isolation always essential?

Background: The role of pulmonary veins (PVs) in persistent atrial fibrillation (AF) perpetuation appears less important than in paroxysmal AF. Electrogram-based substrate ablation is not widely performed as a stand-alone strategy.

Objective: To evaluate PV activity in AF perpetuation and efficacy of our patient-tailored ablation strategy (electrogram-based substrate ablation with or without pulmonary vein isolation [PVI]).
