Coping with unpredictable environments: fine-tune foraging microhabitat use in relation to prey availability in an alpine species.

Microhabitat utilisation holds a pivotal role in shaping a species' ecological dynamics and stands as a crucial concern for effective conservation strategies. Despite its critical importance, microhabitat use has frequently been addressed as static, centering on microhabitat preference. Yet, a dynamic microhabitat use that allows individuals to adjust to fine-scale spatio-temporal prey fluctuations, becomes imperative for species thriving in challenging environments.

Analysis of road traffic accidents involving standing electric scooters reported in newspapers in Italy.

Objective: As the use of electric scooters increased in Italy in the last years, we aimed to estimate the burden of accidents caused by this micro-mobility vehicle and identify characteristics, severity, and type of injuries.

Methods: We conducted a case series analysis of news reports about electric scooter crashes occurring in Italy from January 1, 2019 to September 30, 2020. Events were included when a road traffic accident involved an electric scooter and caused damages or injuries to the driver or others.

Mechanical cardiopulmonary resuscitation in microgravity and hypergravity conditions: A manikin study during parabolic flight.

Introduction: Space travel is expected to grow in the near future, which could lead to a higher burden of sudden cardiac arrest (SCA) in astronauts. Current methods to perform cardiopulmonary resuscitation in microgravity perform below earth-based standards in terms of depth achieved and the ability to sustain chest compressions (CC). We hypothesised that an automated chest compression device (ACCD) delivers high-quality CC during simulated micro- and hypergravity conditions.

Hypothermic Cardiac Arrest With Full Neurologic Recovery After Approximately Nine Hours of Cardiopulmonary Resuscitation: Management and Possible Complications.

We describe full neurologic recovery from accidental hypothermia with cardiac arrest despite the longest reported duration of mechanical cardiopulmonary resuscitation (CPR) and extracorporeal life support (8 hours, 42 minutes). Clinical data and blood samples were obtained from emergency medical services (EMS) and the intensive care department. A 31-year-old man experienced a witnessed hypothermic cardiac arrest with a core temperature of 26°C (78.

Implementation of a mechanical CPR device in a physician staffed HEMS - a prospective observational study.

In this prospective, observational study we describe the incidence and characteristics of out of hospital cardiac arrest (OHCA) cases who received mechanical CPR, after the implementation of a mechanical CPR device (LUCAS 2; Physio Control, Redmond, WA, USA) in a physician staffed helicopter emergency medical service (HEMS) in South Tyrol, Italy. During the study period (06/2013-04/2016), 525 OHCA cases were registered by the dispatch centre, 271 (51.6%) were assisted by HEMS.

Mortality in Multicenter Critical Care Trials: An Analysis of Interventions With a Significant Effect.

Objectives: We aimed to identify all treatments that affect mortality in adult critically ill patients in multicenter randomized controlled trials. We also evaluated the methodological aspects of these studies, and we surveyed clinicians' opinion and usual practice for the selected interventions.

Data Sources: MEDLINE/PubMed, Scopus, and Embase were searched.

Full recovery after prolonged cardiac arrest and resuscitation with mechanical chest compression device during helicopter transportation and percutaneous coronary intervention.

Background: Despite early cardiopulmonary resuscitation (CPR) by bystanders and early advanced cardiac life support (ACLS) maneuvers, some patients present to the emergency department with persistent cardiac arrest caused by a coronary artery occlusion. Although emergency percutaneous intervention (PCI) has been shown to be effective in improving survival, transporting patients in cardiac arrest to the hospital is not considered to be effective, due to the poor quality of CPR in the ambulance. In the case reported here, a mechanical chest compression device was used while transporting the patient by helicopter emergency medical services (HEMS).

Effect of mild hypothermic cardiopulmonary bypass on the amplitude of somatosensory-evoked potentials.

Background: Several neurophysiological techniques are used to intraoperatively assess cerebral functioning during surgery and intensive care, but the introduction of hypothermia as a means of intraoperative neuroprotection has brought their reliability into question. The present study aimed to evaluate the effect of mild hypothermia on somatosensory-evoked potentials' (SSEPs) amplitude and latency in a cohort of cardiopulmonary bypass (CPB) patients as the temperature reached the steady-state.

Materials And Methods: The amplitude and latency of 4 different SSEP signals--N9, N13, P14/N18 interpeak, and N20/P25--were evaluated retrospectively in 84 patients undergoing CPB during normothermic (36°C±0.

Brain emboli distribution and differentiation during cardiopulmonary bypass.

Objective: Cardiopulmonary bypass (CPB) is a lifesaving practice in cardiac surgery, but its use frequently is associated with cerebral injury and neurocognitive dysfunctions. Despite the involvement of numerous factors, microembolism occurring during CPB seems to be one of the main mechanisms leading to such alterations. The aim of the present study was to characterize the occurrence of cerebral microembolism with reference to microembolic amount, nature, and distribution in different combinations of cardiac procedures and CPB on the microembolic load.

Pump flow changes do not impair sublingual microcirculation during cardiopulmonary bypass.

Objective: The flow rate of the cardiopulmonary bypass (CPB) pump used in cardiac surgery often undergoes inherent fluctuations ranging from 10% to 20% of its theoretic value. However, the effects of such alterations remain unknown. In the present study, the authors investigated whether such variations could induce changes in the microvascular flow, which is considered a primary indicator of poor perfusion.

Haemodynamics and oxygenation improvement induced by high frequency percussive ventilation in a patient with hypoxia following cardiac surgery: a case report.

Introduction: High frequency percussive ventilation is a ventilatory technique that delivers small bursts of high flow respiratory gas into the lungs at high rates. It is classified as a pneumatically powered, pressure-regulated, time-cycled, high-frequency flow interrupter modality of ventilation. High frequency percussive ventilation improves the arterial partial pressure of oxygen with the same positive end expiratory pressure and fractional inspiratory oxygen level as conventional ventilation using a minor mean airway pressure in an open circuit.

Microembolic signals and strategy to prevent gas embolism during extracorporeal membrane oxygenation.

Background: Extracorporeal membrane oxygenation (ECMO) supplies systemic blood perfusion and gas exchange in patients with cardiopulmonary failure. The current literature lacks of papers reporting the possible risks of microembolism among the complications of this treatment.In this study we present our preliminary experience on brain blood flow velocity and emboli detection through the transcranial Doppler monitoring during ECMO.
