Factors influencing prehospital physicians' decisions to initiate advanced resuscitation for asystolic out-of-hospital cardiac arrest patients.

Background: The decision to initiate or continue advanced life support (ALS) in out-of-hospital cardiac arrest (OHCA) could be difficult due to the lack of information and contextual elements, especially in non-shockable rhythms. This study aims to explore factors associated with clinicians' decision to initiate or continue ALS and the conditions associated with higher variability in asystolic patients.

Methods: This retrospective observational study enrolled 2653 asystolic patients on whom either ALS was attempted or not by the emergency medical services (EMS) physician.

Stenting versus balloon dilatation in patients with tracheal benign stenosis: The STROBE trial.

Background: It is well known that benign tracheal stenosis represents an obstacle to open surgery, and that its treatment could be challenging. Two endoscopic techniques have so far been adopted to restore tracheal patency: balloon dilatation (BA) through laryngoscopy, and tracheal stenting (ST) with rigid bronchoscopy. The main objective of this study was to compare the efficacy of BA and ST to treat benign tracheal stenosis not eligible for surgery.

Risk Factors for Pulmonary Air Leak and Clinical Prognosis in Patients With COVID-19 Related Acute Respiratory Failure: A Retrospective Matched Control Study.

Background: The role of excessive inspiratory effort in promoting alveolar and pleural rupture resulting in air leak (AL) in patients with SARS-CoV-2 induced acute respiratory failure (ARF) while on spontaneous breathing is undetermined.

Methods: Among all patients with COVID-19 related ARF admitted to a respiratory intensive care unit (RICU) and receiving non-invasive respiratory support, those developing an AL were and matched 1:1 [by means of PaO2/FiO2 ratio, age, body mass index-BMI and subsequent organ failure assessment (SOFA)] with a comparable population who did not (NAL group). Esophageal pressure (ΔP) and dynamic transpulmonary pressure (ΔP) swings were compared between groups.

External validation and insights about the calibration of the return of spontaneous circulation after cardiac arrest (RACA) score.

Background: The return of spontaneous circulation (ROSC) after cardiac arrest (RACA) score was developed as a tool to predict ROSC probability (pROSC) based on easily available information and it could be useful to compare the performances of different EMS agencies or the effects of eventual interventions.We performed an external validation of the RACA score in a cohort of out of hospital cardiac arrest (OHCA) patients managed by the EMS of the metropolitan city of Bologna, Italy.

Methods: We analyzed data from 2,310 OHCA events prospectively collected between January 2009 and June 2021.

Molecular Mechanisms and Physiological Changes behind Benign Tracheal and Subglottic Stenosis in Adults.

Laryngotracheal stenosis (LTS) is a complex and heterogeneous disease whose pathogenesis remains unclear. LTS is considered to be the result of aberrant wound-healing process that leads to fibrotic scarring, originating from different aetiology. Although iatrogenic aetiology is the main cause of subglottic or tracheal stenosis, also autoimmune and infectious diseases may be involved in causing LTS.

Changes in Clinical Characteristics and Outcomes of Patients Admitted to Inpatient Cardiac Rehabilitation.

Aims: Cardiac rehabilitation (CR) has proven to be effective and beneficial in middle-aged and older patients. However, solid data in large cohorts of elderly individuals are yet to be explored. This retrospective study investigated the general characteristics, outcomes, and the level of response of patients referred to CR over 13 consecutive years.

Pulmonary Stretch and Lung Mechanotransduction: Implications for Progression in the Fibrotic Lung.

Lung fibrosis results from the synergic interplay between regenerative deficits of the alveolar epithelium and dysregulated mechanisms of repair in response to alveolar and vascular damage, which is followed by progressive fibroblast and myofibroblast proliferation and excessive deposition of the extracellular matrix. The increased parenchymal stiffness of fibrotic lungs significantly affects respiratory mechanics, making the lung more fragile and prone to non-physiological stress during spontaneous breathing and mechanical ventilation. Given their parenchymal inhomogeneity, fibrotic lungs may display an anisotropic response to mechanical stresses with different regional deformations (micro-strain).

A retrospective review of the role of B-mode and color Doppler ultrasonography in the investigation of primary hyperparathyroidism: Features that differentiate benign from malignant lesions.

Purpose: To identify the variant features encountered in parathyroid abnormalities and document those suggesting malignant change.

Materials And Methods: Data were collected from a cohort of patients who underwent investigation for primary hyperparathyroidism over a 10-year period. Ultrasonographic features: shape, presence of calcification, cystic changes, heterogeneous echogenicity, vascularity, capsular thickening, local invasion, and vascularity were reviewed retrospectively and were used to correlate with final histological findings.

Incidental finding of bronchial diverticula in a non-smoker population: evaluation on thin-section CT.

Bronchial diverticula have been described as a common radiological finding in smoker patients with COPD, but the specificity of this sign should be further investigated. Thus, the aim of our study was to evaluate the prevalence of diverticula in a cohort of non-smoker subjects. Between February and July 2012, 2438 patients were admitted to our Radiology Unit to undergo a chest CT.

Predictive outcome indexes in neonatal Congenital Diaphragmatic Hernia.

Objective: We examined the reliability of the main prenatal and postnatal prognosis-related indexes that can be used to evaluate congenital diaphragmatic hernia (CDH) outcome.

Methods: Seventy-seven neonates with CDH were analyzed according to CDH prognosis-related factors, divided into prenatal findings, postnatal clinical values and postnatal predictive outcome scores applied at birth and within the first 12-24 h. The data are compared between two groups: survivors and non-survivors.

Update of recommendations for Analgosedation in pediatric intensive care unit.

Effective and adequate therapy to control pain and stress are essential in managing children in Pediatric Intensive Care Unit (PICU) undergoing painful invasive procedures, this should be, but is not yet, one of our main aims. Aware that this difficult mission must be pursued in a systematic, multimodal and multitasking way, the Studying Group on Analgosedation in PICU from the Italian Society of Neonatal and Paediatric Anesthesia and Intensive Care (SARNePI) is providing its recommendations.

Preoperative evaluation in infants and children: recommendations of the Italian Society of Pediatric and Neonatal Anesthesia and Intensive Care (SARNePI).

Background: The preoperative assessment involves the process of evaluating the patient's clinical condition, which is intended to define the physical status classification, eligibility for anesthesia and the risks associated with it, thus providing elements to select the most appropriate and individualized anesthetic plan. The aim of this recommendation was provide a framework reference for the preoperative evaluation assessment of pediatric patients undergoing elective surgery or diagnostic/therapeutic procedures.

Methods: We obtained evidence concerning pediatric preoperative evaluation from a systematic search of the electronic databases MEDLINE and Embase between January 1998 and February 2012.

Neurally adjusted ventilatory assist in weaning of neonates affected by congenital diaphragmatic hernia.

Objective: The aim of the study is to evaluate the application of neurally adjusted ventilatory assist (NAVA) in the respiratory weaning of patients affected by congenital diaphragmatic hernia (CDH).

Methods: We analyzed the NAVA weaning in 12 neonates affected by CDH, relating the effectiveness of the electrical activation of the diaphragm (EAdi) signal to the type of CDH repair (with or without patch), the size of the patch, the stomach and His angle position, and the trend evaluation of some cardiorespiratory parameters with NAVA compared to pressure-support-ventilation (PSV).

Results: 5 neonates submitted to primary repair showed a regular EAdi signal and were successfully weaned with NAVA.

Neonatal congenital diaphragmatic hernia: respiratory and blood-gas derived indices in choosing surgical timing.

Background: Congenital diaphragmatic hernia (CDH) still has a high mortality despite advanced assistance techniques. The aim of this study is to verify the validity of five respiratory and blood-gas-derived indices in defining presurgical stabilization: the oxygenation index (OI), the alveolar-arterial O(2) gradient (A-aDO(2)), the arterial-alveolar O(2) tension ratio (a/AO(2)), the arterial pH and the PaCO(2).

Methods: The study involved 73 neonates with CDH where the accuracy of stabilization was assessed through the survival percentage and the contemporary behaviour of mean arterial pressure (MAP), ductal shunting, urine output and lactate levels.

Cardiocirculatory intraoperative assessment during single-shot caudal anaesthesia in children: comparison between levobupivacaine and ropivacaine.

Background: Caudal block with levobupivacaine or ropivacaine is the most commonly used regional anaesthesia in children.

Methods: The aim of study was to compare the cardiocirculatory profile induced in two matched groups of young patients, submitted to caudal anaesthesia with levobupivacaine or ropivacaine for an elective subumbilical surgery. Sixty children were enrolled: thirty received levopubivacaine 0.

Effects of epidural analgesia on labor length, instrumental delivery, and neonatal short-term outcome.

Purpose: We aimed to clarify whether the short-term adverse neonatal outcomes associated with epidural analgesia are due to the epidural analgesia itself or to the instrumental delivery.

Methods: A retrospective case-control study was conducted to evaluate the relationship between epidural analgesia, labor length, and perinatal outcomes. A total of 350 pregnant women at term who delivered under epidural analgesia (cases) were compared with 1400 patients without epidural analgesia (controls).

Combined left pulmonary artery sling transposition and tracheal lobe resection through a median sternotomy: a case report.

Introduction: The aim of this paper was to report the management of a very rare malformative association of Left Pulmonary Artery (LPA) sling and Tracheal Lobe which is not still reported in scientific literature.

Materials And Methods: The Authors describe the clinical case of a 6 years old girl that was admitted for chronic respiratory symptoms associated with recurrent upper respiratory infections. The CT-scan with virtual bronchoscopy showed an ectopic bronchus arising from the right side of the upper third of the trachea and ending in an accessory pulmonary lobe, covered by normal pleura, located in the upper mediastinum.

Acute liver failure associated with a prolonged course of acetaminophen at recommended dosages in paediatric age.

Acetaminophen is considered as a safe analgesic and antipyretic drug in paediatric age. The main problem in the use of acetaminophen is acute liver failure after an overdose or an acute intoxication. We report a case of fulminant liver failure and spontaneous recovery in a patient treated with a prolonged course of acetaminophen at recommended dosages.

Hydroxyethyl starch 130/0.42/6:1 for perioperative plasma volume replacement in children: preliminary results of a European Prospective Multicenter Observational Postauthorization Safety Study (PASS).

Background: Several clinical studies have shown that hydroxyethyl starch (HES) may be as effective and safe as, but less expensive than, albumin when used for perioperative plasma volume replacement (PVR) in children. The new third generation HES 130/0.42 solution was designed to reduce adverse drug reactions (ADRs) and improve safety while maintaining efficacy.

Rhabdomyolysis and respiratory failure: rare presentation of carnitine palmityl-transferase II deficiency.

Carnitine palmityl-transferase (CPT) II deficiency is a rare disorder of the fatty acid beta-oxidation cycle. CPT II deficiency can be associated with rhabdomyolysis in particular conditions that increase the requirement for fatty acid oxidation, such as low-carbohydrate and high-fat diet, fasting, exposure to excessive cold, lack of sleep and prolonged exercise. The best known CPT II deficiency is the muscular form with episodic muscle necrosis and paroxysmal myoglobinuria after prolonged exercise.
