[Radiofrequency transcatheter ablation of the left lateral Kent bundle in a premature newborn after 28 weeks of pregnancy with prenatal diagnosis of incessant tachycardia: 28-year follow-up].

A case of incessant tachycardia diagnosed at the seventh month of pregnancy conditioning hydrops fetalis is described. Delivery was induced by caesarean section. Atrioventricular reciprocating tachycardia was due to the involvement of a left lateral accessory pathway refractory to multiple antiarrhythmic drugs and was often associated with ipsilateral left bundle branch block at a slower rate.

Severe COVID-19 ARDS Treated by Bronchoalveolar Lavage with Diluted Exogenous Pulmonary Surfactant as Salvage Therapy: In Pursuit of the Holy Grail?

Background: Severe pneumonia caused by coronavirus disease 2019 (COVID-19) is characterized by inflammatory lung injury, progressive parenchymal stiffening and consolidation, alveolar and airway collapse, altered vascular permeability, diffuse alveolar damage, and surfactant deficiency. COVID-19 causes both pneumonia and acute respiratory distress syndrome (COVID-19 ARDS). COVID-19 ARDS is characterized by severe refractory hypoxemia and high mortality.

Beyond false belief: theory of mind in young, young-old, and old-old adults.

Theory of mind (ToM) refers to humans' ability to recognize the existence of mental states, such as beliefs, emotions, and desires. The literature on ToM in aging and on the relationship between ToM and other cognitive functions, like executive functions, is not homogenous. The aim of the present study was to explore the course of ToM and to investigate the role of working memory, inhibition, and language on the possible age differences in ToM.

Improving Parkinson's disease identification through evolutionary-based feature selection.

Parkinson's disease (PD) automatic identification has been actively pursued over several works in the literature. In this paper, we deal with this problem by applying evolutionary-based techniques in order to find the subset of features that maximize the accuracy of the Optimum-Path Forest (OPF) classifier. The reason for the choice of this classifier relies on its fast training phase, given that each possible solution to be optimized is guided by the OPF accuracy.

Longitudinal effects of theory of mind on later peer relations: the role of prosocial behavior.

Children's peer relations represent a key aspect of school adjustment. However, little is known about their social-cognitive precursors. To address this gap, the authors followed 70 children across the transition to primary school.

Reading minds: the relation between children's mental state knowledge and their metaknowledge about reading.

The relation between children's mental state knowledge and metaknowledge about reading was examined in 2 studies. In Study 1, 196 children (mean age = 9 years) were tested for verbal ability (VA), metaknowledge about reading, and mental state words in a story task. In Study 2, the results of Study 1 were extended by using a cross-lagged design and by investigating older children (N = 71, mean ages = 10 years at Time 1 and 11 years at Time 2) for mental state knowledge, metaknowledge about reading, and VA.

Aging and everyday memory: the beneficial effect of memory training.

The authors investigated elderly people's ability to benefit from specific memory training. Empirical evidence of cognitive aging shows a deterioration in working memory ability but also suggests that elderly people maintain the ability to acquire new information and strategies. The aim of the present study was to investigate the effects of two different mnemonic strategies (Loci mnemonic vs.

[Single lung transplantation retrospective analysis of intraoperative cardiovascular problems].

Background: Analysis of haemodynamic problems during single-lung transplantation and of methodologies employed for their treatment.

Design Of The Study: clinical retrospective study.

Setting: General University Hospital.

Monitoring aspects during port-access cardiac surgery.

Objective: To report the experience gained at our Cardiosurgical Centre with the recently introduced port-access technique.

Experimental Design: Prospective collection of data from the month of October 1997.

Setting: Regional University HospitaL Patients: Adult patients undergoing coronary bypass graft or mitral valve surgery.

[Risk management from the psychological point of view].

Main directions of psychological research in risk factors and risk reducing interventions in work settings are discussed. Cognitive and social communication components that enhance or reduce risk behaviours are stressed. The author states that knowing and valuing risks are only a portion of the cognitive factors implied in the process, not sufficient to explain phenomena.

[Current views on the use of vasodilators in pulmonary hypertension].

Vasodilators represent one of the main steps for the medical treatment of pulmonary hypertension; the rationale for their use is the reversibility of the pulmonary vasoconstriction, to be tested with a correct pharmacological trial. In this report the authors consider the use of calcium-channel blockers, prostaglandin and nitric oxide. Calcium blockers, the only drugs active when administered orally, provide a satisfactory clinical response in 25-30% of treated patients.

Management of anesthesia during dynamic cardiomyoplasty.

Study Objective: To review experience with anesthetic management in ten patients undergoing dynamic cardiomyoplasty (CMPL), a new surgical technique that serves as an alternative to heart transplantation.

Design: Retrospective clinical study.

Setting: Cardiothoracic operating room at a university hospital.

[Comparison between propofol and isoflurane in patients undergoing aorto-coronary bypass. Effect on systemic and coronary circulation].

The Authors report their experience with the use of two different anaesthetic techniques (propofol-fentanil versus isoflurane-fentanyl) for induction and maintenance of anaesthesia in patients undergoing coronary artery surgery. Haemodynamic data (regarding systemic and coronary circulation) showed an almost similar pattern of change after induction, intubation, skin incision and sterotomy, except for a greater decrease of systemic vascular resistances after induction in patients who received propofol. Cardiac output decreased more in the isoflurane group while changes in coronary sinus flow were equal in the two groups.

Biochemical changes induced in the myocardial cell during cardioplegic arrest supplemented with creatine phosphate.

The purpose of this work was to evaluate the biochemical changes in the myocardial cell using cardioplegia supplemented with creatine phosphate (CP). Many previous studies have demonstrated the beneficial effect of CP on the ischemic myocardium and its mechanism of action has been assumed to be mainly extracellular. Based on the assumption that CP could also exert some influence on myocardial cellular metabolism, this investigation was carried out.

[Pseudoaneurysm of the left ventricle. Description of a clinical case].

The paper describes a case of pseudoaneurysm of the left ventricle following an earlier operation to close a post-infarction interventricular defect. The nosological entity is described paying particular attention to preoperative functional tests and intraoperative anesthesiological procedures. The careful monitoring of refilling pressure and cardiac load represents an essential for the correct infusion of drugs and optimal volemic refilling.

[Role of creatine phosphate in myocardial protection in heart surgery].

The Authors report their experience with the use of Creatine Phosphate (CP) in cardiac surgery. Forty patients undergoing mitral valve replacement are randomly divided into two groups: the former is treated with plain cardioplegia, the latter with CP-enriched cardioplegia at a concentration of 10 mmol/l. A sample of papillary muscle, obtained from the removed valve, is studied by means of spectrophotometric analysis in order to assess the enzyme activities and the intermediate metabolites of the different biochemical pathways of the myocardial cell.
