An experimental study of participants' response to the sudden appearance of a fire emergency in a virtual environment (VE) and of the adaptivity of their response pattern is presented. A VE has been built in which participants meet two situations regarding the unexpected outbreak of fire.

More than 10 years ago, Tart (1990) described virtual reality (VR) as a technological model of consciousness offering intriguing possibilities for developing diagnostic, inductive, psychotherapeutic, and training techniques that can extend and supplement current ones. To exploit and understand this potential is the overall goal of the "Telemedicine and Portable Virtual Environment in Clinical Psychology"—VEPSY UPDATED—a European Community– funded research project (IST-2000-25323, www.cybertherapy.info). Particularly, its specific goal is the development of different PC-based virtual reality modules to be used in clinical assessment and treatment of social phobia, panic disorders, male sexual disorders, obesity, and eating disorders. The paper describes the clinical and technical rationale behind the clinical applications developed by the project. Moreover, the paper focuses its analysis on the possible role of VR in clinical psychology and how it can be used for therapeutic change. [ABSTRACT FROM AUTHOR]

Many of us grew up with the naive assumption that couches are the best used therapeutic tools in psychotherapy. But tools for psychotherapy are evolving in a much more complex environment than a designer's chaise lounge. In particular, virtual reality (VR) devices have the potential for appearing soon in many consulting rooms. The use of VR in medicine is not a novelty. Applications of virtual environments for health care have been developed in the following areas: surgical procedures (remote surgery or telepresence, augmented or enhanced surgery, and planning and simulation of procedures before surgery); preventive medicine and patient education; medical education and training; visualization of massive medical databases; and architectural design for health care facilities. However, there is a growing recognition that VR can play an important role in clinical psychology, too. To exploit and understand this potential is the main goal of the Telemedicine and Portable Virtual Environment in Clinical Psychology - VEPSY Updated - a European Community-funded research project (IST-2000-25323, http://www.vepsy.com). The project will provide innovative tools - telemedicine and portable - for the treatment of patients, clinical trials to verify their viability, and action plans for dissemination of its results to an extended audience - potential users and influential groups. The project will also develop different personal computer (PC)-based virtual reality modules to be used in clinical assessment and treatment. In particular, the developed modules will address the following pathologies: anxiety disorders; male impotence and premature ejaculation; and obesity, bulimia, and binge-eating disorders.

Objectives: The non-oncological population is relatively under-represented among end-of-life (EOL) patients managed by palliative care (PC) services, and the effects of different PC delivery models are understudied in this population.This retrospective observational study on routinely collected data aimed at evaluating the effects of the extension from workday-only to 24/7 mixed hands-on and advisory home PC service on emergency department (ED) access and emergency medical services (EMS) interventions needed by non-oncological patients during their last 90 days of life, and their probability to die in hospital., Methods: A before-and-after design was adopted comparing preimplementation and postimplementation periods (2018-2019 and 2021-22).We used a difference-in-differences approach to estimate changes in ED access and EMS intervention rates in the postintervention period through binomial negative regression. The oncological population, always exposed to 24/7 PC, was used as a control. A robust Poisson regression model was adopted to investigate the differences regarding hospital mortality. The analyses were adjusted for age, sex and disease grouping by the system involved. Results were reported as incidence rate ratios (IRRs) and ORs., Results: A total of 2831 patients were enrolled in the final analysis.After the implementation of 24/7 home PC, both ED admissions (IRR=0.390, p<0.001) and EMS interventions (IRR=0.413, p<0.001) dropped, as well as the probability to die in hospital (OR=0.321, p<0.001)., Conclusions: The adoption of a 24/7 mixed hands-on and advisory model of home PC could have relevant effects in terms of ED access and EMS use by non-oncological EOL patients under PC., Trial Regisration Number: NCT05640076., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Various regional anesthesia techniques have been studied for blunt chest wall trauma over the past decades, but their impact on patient outcomes remains unclear. This systematic review and Bayesian network meta-analysis aimed to identify the most effective regional anesthesia techniques for different outcomes in blunt thoracic trauma patients., Methods: We searched Medline, EMBASE, Scopus, and Cochrane databases for randomized controlled trials comparing regional anesthesia techniques (thoracic epidural, erector spinae plane block, serratus anterior plane block, intercostal block, paravertebral block, intrapleural block, retrolaminar block) and standard intravenous analgesia. Eligible studies reported at least one of the following outcomes: pain control, ICU and hospital length of stay, mechanical ventilation duration, pneumonia incidence, and additional analgesic use. Bayesian network meta-analysis models were created for each outcome, and confidence in results was assessed using the CINeMA framework., Results: We included 27 randomized controlled trials with 1586 patients. Thoracic epidural consistently showed efficacy in reducing pain at 24 h, mechanical ventilation duration, and ICU and hospital stays. The erector spinae plane block also reduced pain and hospital stay. Confidence in these results was low to moderate, primarily due to imprecision., Conclusions: Various locoregional techniques are being investigated for managing pain in blunt thoracic trauma, with thoracic epidural showing consistent positive effects on pain and other key outcomes. Fascial blocks are emerging as potential alternatives with similar pain relief, though evidence on other outcomes is limited. Future studies should compare the efficacy of these techniques on more definitive endpoints., Competing Interests: Declaration of competing interest The Authors have no conflicts of interest to disclose., (Copyright © 2024 Elsevier Inc.

Background: The contemporary management of mass casualty incidents (MCIs) relies on the effective application of predetermined, dedicated response plans based on current best evidence. Currently, there is limited evidence regarding the factors influencing the accuracy of first responders (FRs) in applying the START protocol and the associated prehospital times during the response to MCIs. The objective of this study was to investigate factors affecting FRs' accuracy in performing prehospital triage in a series of simulated mass casualty exercises. Secondly, we assessed factors affecting triage-to-scene exit time in the same series of exercises., Methods: This retrospective study focused on simulated casualties in a series of simulated MCIs Full Scale Exercises. START triage was the triage method of choice. For each Full-Scale Exercise (FSEx), collected data included exercise and casualty-related information, simulated casualty vital parameters, simulated casualty anatomic lesions, scenario management times, and responder experience., Results: Among the 1090 casualties included in the primary analysis, 912 (83.6%) were correctly triaged, 137 (12.6%) were overtriaged, and 41 (3.7%) were undertriaged. The multinomial regression model indicated that increasing heart rate (RRR = 1.012, p = 0.008), H-AIS (RRR = 1.532, p < 0.001), and thorax AIS (T-AIS) (RRR = 1.344, p = 0.007), and lower ISS (RRR = 0.957, p = 0.042) were independently associated with overtriage. Undertriage was significantly associated with increasing systolic blood pressure (RRR = 1.013, p = 0.005), AVPU class (RRR = 3.104 per class increase), and A-AIS (RRR = 1.290, p = 0.035). The model investigating the factors associated with triage-to-scene departure time showed that the assigned prehospital triage code red (TR = 0.841, p = 0.002), expert providers (TR = 0.909, p = 0.015), and higher peripheral oxygen saturation (TR = 0.998, p < 0.001) were associated with a reduction in triage-to-scene departure time. Conversely, increasing ISS was associated with a longer triage-to-scene departure time (TR = 1.004, 0.017)., Conclusions: Understanding the predictors influencing triage and scene management decision-making by healthcare professionals responding to a mass casualty may facilitate the development of tailored training pathways regarding mass casualty triage and scene management., (© 2024.

Trauma is a leading cause of death and disability worldwide across all age groups, with traumatic cardiac arrest (TCA) presenting a significant economic and societal burden due to the loss of productive life years. Despite TCA's high mortality rate, recent evidence indicates that survival with good and moderate neurological recovery is possible. Successful resuscitation in TCA depends on the immediate and simultaneous treatment of reversible causes according to pre-established algorithms. The HOTT protocol, addressing hypovolaemia, oxygenation (hypoxia), tension pneumothorax, and cardiac tamponade, forms the foundation of TCA management. Advanced interventions, such as resuscitative thoracotomy and resuscitative endovascular balloon occlusion of the aorta (REBOA), further enhance treatment. Contemporary approaches also consider metabolic factors (e.g. hyperkalaemia, calcium imbalances) and hemostatic resuscitation. This narrative review explores the advanced management of TCA and peri-arrest states, discussing the epidemiology and pathophysiology of peri-arrest and TCA. It integrates classic TCA management strategies with the latest evidence and practical applications., (© 2024. The Author(s).)

Background: Out-of-hospital cardiac arrest (OHCA) is a major health concern in Europe, leading to significant morbidity and mortality. Survivors often suffer from cognitive deficits, anxiety, and depression, that affect significantly their quality of life. Current post-discharge care is inconsistent and frequently overlooks subtle but disabling symptoms. The ENFORCER trial aims to significantly enhance the health and quality of life of OHCA survivors by providing a comprehensive, accessible, and user-friendly internet-based lifestyle intervention., Methods: ENFORCER is a multicentre, parallel group randomized controlled trial involving OHCA survivors aged 18-80 years with cognitive impairment or anxiety/depression measured through validated instruments.Participants will be randomized 1:1 to the intervention or the control group. The intervention group will receive a one-year program via a secure web application, offering cognitive, emotional, and physical rehabilitation support. The control group will receive standard care.The primary outcome is the difference in the proportion of patients without cognitive or emotional symptoms between the two groups after one year.Secondary outcomes include changes in the level of patients' cognitive and emotional symptoms, quality of life, sleep quality, sexual interest and satisfaction, and caregivers' burden, quality of life, sleep quality and emotional symptoms in the two groups., Discussion: The trial addresses the need for consistent post-discharge care, and the timely detection and treatment of cognitive and emotional problems. The internet-based approach allows to potentially reach many patients, ensuring cost-effectiveness and high adherence rates.The study results could establish a standard for post-OHCA care, improving long-term recovery and quality of life for survivors.Trial registration.The trial is registered at clinicaltrials.gov (NCT06395558)., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

Venovenous bypass (VVB) use during liver transplantation (LT) is notably variable among the centres and it is actually restricted to surgically complex cases, severely unstable recipients or grafts from high-risk donors. Historically, VVB was associated with the classical LT with caval cross clamping, while not much is known about the safety of this technique applied to piggyback LT. This retrospective observational study evaluated the effects of VVB applied to piggyback LT on mortality, hospital outcomes, postoperative graft and other organ dysfunction. We retrospectively collected data about recipient status, surgical complexity and graft quality of all the piggyback LTs performed at the Transplant Unit of IRCCS Azienda Ospedaliero-Universitaria di Bologna, Italy, from January 2012 to December 2022. A propensity score (PS) was built taking into account the variables possibly associated with either VVB choice and the investigated outcomes with the average treatment overlap method. PS-weighted general linear models (GLMs) were developed to investigate the adjusted effect of VVB use on the selected outcomes. The final analysis included 874 LT cases, of whom 74 (8.5%) underwent VVB. The effective sample sizes after PS-weighting were 280.2 and 64.3 patients in the no-VVB and VVB groups, respectively. PS-weighted GLMs did not show any differences regarding hospital and graft-related outcomes. However, significantly higher odds ratios for serum creatinine > 2 mg/dL and AKIN stage 2 or 3 during the first 24 h after ICU admission together with a higher renal replacement therapy need during ICU stay were reported for VVB exposure in the weighted analyses. This study suggests similar mortality and length of stay but a higher risk for postoperative acute kidney injury in patients undergoing piggyback LT with VVB., (© 2024.

Trauma teams play a vital role in providing prompt and specialized care to trauma patients. This study aims to provide a comprehensive description of the presence and organization of trauma teams in Italy. A nationwide cross-sectional epidemiological study was conducted between July and October 2022, involving interviews with 137 designated trauma centers. Centers were stratified based on level: higher specialized trauma centers (CTS), intermediate level trauma centers (CTZ + N) and district general hospital with trauma capacity (CTZ). A standardized structured interview questionnaire was used to gather information on hospital characteristics, trauma team prevalence, activation pathways, structure, components, leadership, education, and governance. Descriptive statistics were used for analysis. Results showed that 53 % of the centers had a formally defined trauma team, with higher percentages in CTS (73 %) compared to CTZ + N (49 %) and CTZ (39 %). The trauma team activation pathway varied among centers, with pre-alerts predominantly received from emergency medical services. The study also highlighted the lack of formally defined massive transfusion protocols in many centers. The composition of trauma teams typically included airway and procedure doctors, nurses, and healthcare assistants. Trauma team leadership was predetermined in 59 % of the centers, with anesthesiologists/intensive care physicians often assuming this role. The study revealed gaps in trauma team education and governance, with a lack of specific training for trauma team leaders and low utilization of simulation-based training. These findings emphasize the need for improvements in trauma management education, governance, and the formalization of trauma teams. This study provides valuable insights that can guide discussions and interventions aimed at enhancing trauma care at both local and national levels in Italy., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Out-of-hospital cardiac arrest (OHCA) is a major public health concern with low survival rates. First responders (FRs) and public access defibrillation (PAD) programs can significantly improve survival, although barriers to response activation persist. The Emilia Romagna region in Italy has introduced a new system, the DAE RespondER App, to improve the efficiency of FR dispatch in response to OHCA. The study aimed to evaluate the association between different logistic factors, FRs' perceptions, and their decision to accept or decline dispatch to an OHCA scene using the DAE RespondER App. A cross-sectional web survey was conducted, querying 14,518 registered FRs using the DAE RespondER app in Emilia Romagna. The survey explored logistic and cognitive-emotional perceptions towards barriers in responding to OHCAs. Statistical analysis was conducted, with responses adjusted using non-response weights. 4,644 responses were obtained (32.0% response rate). Among these, 1,824 (39.3%) had received at least one dispatch request in the past year. Multivariable logistic regression showed that being male, having previous experience with OHCA situations, and having an automated external defibrillator (AED) available at the moment of the call were associated with a higher probability of accepting the dispatch. Regarding FRs' perceptions, logistic obstacles were associated with mission rejection, while higher scores in cognitive-emotional obstacles were associated with acceptance. The study suggests that both logistical and cognitive-emotional factors are associated with FRs' decision to accept a dispatch. Addressing these barriers and further refining the DAE RespondER App can enhance the effectiveness of PAD programs, potentially improving survival rates for OHCA. The insights from this study can guide the development of interventions to improve FR participation and enhance overall OHCA response systems., (© 2023.

Introduction: Guidelines recommend teaching resuscitation from school age; however, little is known about the best methods to provide it. We devised a blended learning program for primary and secondary students (Kids Save Lives - KSL) consisting of brief lectures, practical training with mannequins, and virtual reality. We aimed to evaluate its impact on students' attitudes towards intervening during cardiac arrest and their knowledge about basic life support., Methods: This observational, prospective, before-and-after study assessed attitudes and basic life support knowledge in primary and secondary school children exposed to the KSL program. 20 events were conducted in the metropolitan area of Bologna, Italy. A multiple-choice test (before and after the course) explored attitude, knowledge and perceptions of realism, engagement, and agreement with the virtual reality method., Results: A total of 1,179 students (response rate 81.4%) were included in the final analysis, with 12.89% from primary schools, 5.94% from middle schools, and 81.17% from high schools. Students' willingness to intervene during a cardiac arrest rose from 56.9% to 93.1% (p < 0.001) post-course. The course's realism, engagement, and future prospects received positive feedback, with median scores notably higher in primary schools compared to secondary schools., Conclusion: The blended learning method improved students' understanding of basic life support techniques and their attitude to act during cardiac arrest situations. The positive reception of the virtual reality component underscores technology's potential to bolster engagement and should be further explored for basic life support teaching in schoolchildren., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Introduction: As a result of Industry 5.0's technological advancements, collaborative robots (cobots) have emerged as pivotal enablers for refining manufacturing processes while re-focusing on humans. However, the successful integration of these cutting-edge tools hinges on a better understanding of human factors when interacting with such new technologies, eventually fostering workers' trust and acceptance and promoting low-fatigue work. This study thus delves into the intricate dynamics of human-cobot interactions by adopting a human-centric view. Methods: With this intent, we targeted senior workers, who often contend with diminishing work capabilities, and we explored the nexus between various human factors and task outcomes during a joint assembly operation with a cobot on an ergonomic workstation. Exploiting a dual-task manipulation to increase the task demand, we measured performance, subjective perceptions, eye-tracking indices and cardiac activity during the task. Firstly, we provided an overview of the senior workers' perceptions regarding their shared work with the cobot, by measuring technology acceptance, perceived wellbeing, work experience, and the estimated social impact of this technology in the industrial sector. Secondly, we asked whether the considered human factors varied significantly under dual-tasking, thus responding to a higher mental load while working alongside the cobot. Finally, we explored the predictive power of the collected measurements over the number of errors committed at the work task and the participants' perceived workload. Results: The present findings demonstrated how senior workers exhibited strong acceptance and positive experiences with our advanced workstation and the cobot, even under higher mental strain. Besides, their task performance suffered increased errors and duration during dual-tasking, while the eye behavior partially reflected the increased mental demand. Some interesting outcomes were also gained about the predictive power of some of the collected indices over the number of errors committed at the assembly task, even though the same did not apply to predicting perceived workload levels. Discussion: Overall, the paper discusses possible applications of these results in the 5.0 manufacturing sector, emphasizing the importance of adopting a holistic human-centered approach to understand the human-cobot complex better., Competing Interests: Authors AR and LM were employed by BNP Srl.

Background: Evolving research on resuscitative endovascular balloon occlusion of the aorta (REBOA) as an adjunct treatment for out-of-hospital cardiac arrest mandates uniform recording and reporting of data. A consensus on which variables need to be collected may enable comparing and merging data from different studies. We aimed to establish a standard set of variables to be collected and reported in future REBOA studies in out-of-hospital cardiac arrest., Methods: A four-round stepwise Delphi consensus process first asked experts to propose without restraint variables for future REBOA research in out-of-hospital cardiac arrest. The experts then reviewed the variables on a 5-point Likert scale and ≥75% agreement was defined as consensus. First authors of published papers on REBOA in out-of-hospital cardiac arrest over the last five years were invited to join the expert panel., Results: The data were collected between May 2022 and December 2022. A total of 28 experts out of 34 primarily invited completed the Delphi process, which developed a set of 31 variables that might be considered as a supplement to the Utstein style reporting of research in out-of-hospital cardiac arrest., Conclusions: This Delphi consensus process suggested 31 variables that enable future uniform reporting of REBOA in out-of-hospital cardiac arrest., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: [Guillaume L.

Importance: While the relationship between persistent elevations in intracranial pressure (ICP) and poorer outcomes is well established for patients with traumatic brain injury (TBI), there is no consensus on how ICP measurements should drive treatment choices, and the effectiveness of ICP monitoring remains unknown., Objective: To evaluate the effectiveness of ICP monitoring on short- and mid-term outcomes of patients with TBI., Design, Setting, and Participants: CREACTIVE was a prospective cohort study that started in March 2014 and lasted 5 years. More than 8000 patients with TBI were enrolled at 83 intensive care units (ICUs) from 7 countries who joined the CREACTIVE Consortium. Patients with TBI who met the Brain Trauma Foundation guidelines for ICP monitoring were selected for the current analyses, which were performed from January to November 2022., Exposure: Patients who underwent ICP monitoring within 2 days of injury (exposure group) were propensity score-matched to patients who were not monitored or who underwent monitoring 2 days after the injury (control group)., Main Outcome and Measure: Functional disability at 6 months as indicated by Glasgow Outcome Scale-Extended (GOS-E) score., Results: A total of 1448 patients from 43 ICUs in Italy and Hungary were eligible for analysis. Of the patients satisfying the ICP-monitoring guidelines, 503 (34.7%) underwent ICP monitoring (median [IQR] age: 45 years [29-61 years]; 392 males [77.9%], 111 females [22.1%]) and 945 were not monitored (median [IQR] age: 66 years [48-78 years]; 656 males [69.4%], 289 females [30.6%]). After matching to balance the variables, worse 6-month recovery was observed for monitored patients compared with nonmonitored patients (death/vegetative state: 39.2% vs 40.6%; severe disability: 33.2% vs 25.4%; moderate disability: 15.7% vs 14.9%; good recovery: 11.9% vs 19.1%, respectively; P = .005). Monitored patients received medical therapies significantly more frequently., Conclusions and Relevance: In this cohort study, ICP monitoring was associated with poorer recovery and more frequent medical interventions with their relevant adverse effects. Optimizing the value of ICP monitoring for TBI requires further investigation on monitoring indications, clinical interventions, and management protocols.

Digital health assistants (DHAs) are conversational agents incorporated into health systems' interfaces, exploiting an intuitive interaction format appreciated by the users. At the same time, however, their conversational format can evoke interactional practices typical of health encounters with human doctors that might misguide the users. Awareness of the similarities and differences between novel mediated encounters and more familiar ones helps designers avoid unintended expectations and leverage suitable ones. Focusing on adherence apps, we analytically discuss the structure of DHA-patient encounters against the literature on physician-patient encounters and the specific affordances of DHAs. We synthesize our discussion into a design checklist and add some considerations about DHA with unconstrained natural language interfaces.

Background: In adults with refractory out-of-hospital cardiac arrest, when conventional cardiopulmonary resuscitation (CPR) alone does not achieve return of spontaneous circulation, extracorporeal CPR is attempted to restore perfusion and improve outcomes. Considering the contrasting findings of recent studies, we conducted a meta-analysis of randomized controlled trials to ascertain the effect of extracorporeal CPR on survival and neurological outcome., Methods: Pubmed via MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were searched up to February 3, 2023, for randomized controlled trials comparing extracorporeal CPR versus conventional CPR in adults with refractory out-of-hospital cardiac arrest. Survival with a favorable neurological outcome at the longest follow-up available was the primary outcome., Results: Among four randomized controlled trials included, extracorporeal CPR compared with conventional CPR increased survival with favorable neurological outcome at the longest follow-up available for all rhythms (59/220 [27%] vs. 39/213 [18%]; OR = 1.72; 95% CI, 1.09-2.70; p = 0.02; I 2  = 26%; number needed to treat of 9), for initial shockable rhythms only (55/164 [34%] vs. 38/165 [23%]; OR = 1.90; 95% CI, 1.16-3.13; p = 0.01; I 2  = 23%; number needed to treat of 7), and at hospital discharge or 30 days (55/220 [25%] vs. 34/212 [16%]; OR = 1.82; 95% CI, 1.13-2.92; p = 0.01; I 2  = 0.0%). Overall survival at the longest follow-up available was similar (61/220 [25%] vs. 34/212 [16%]; OR = 1.82; 95% CI, 1.13-2.92; p = 0.59; I 2  = 58%)., Conclusions: Extracorporeal CPR compared with conventional CPR increased survival with favorable neurological outcome in adults with refractory out-of-hospital cardiac arrest, especially when the initial rhythm was shockable., Review Registration: PROSPERO CRD42023396482., (© 2023 The Authors.

Background: First responder programs were developed to speed up access to cardiopulmonary resuscitation and defibrillation for out-of-hospital cardiac arrest (OHCA) victims. Little is known about the factors influencing the efficiency of the first responders arriving before the EMS and, therefore, effectively contributing to the chain of survival., Objectives: The primary objective of this retrospective observational study was to identify the factors associated with first responders' arrival before EMS in the context of a regional first responder program arranged to deliver automated external defibrillators on suspected OHCA scenes., Methods: Eight hundred ninety-six dispatches where FRs intervened were collected from 2018 to 2022. A robust Poisson regression was performed to estimate the role of the time of day, the immediate availability of a defibrillator, the type of first responder, distances between the responder, the event and the dispatched vehicle, and the nearest available defibrillator on the probability of responder arriving before EMS. Moreover, a geospatial logistic regression model was built., Results: Responders arrived before EMS in 13.4% of dispatches and delivered a shock in 0.9%. The immediate availability of a defibrillator for the responder (OR = 3.24) and special categories such as taxi drivers and police (OR = 1.74) were factors significantly associated with the responder arriving before EMS. Moreover, a geospatial effect suggested that first responder programs may have a greater impact in rural areas., Conclusions: When dispatched to OHCA scenes, responders already carrying defibrillators could more probably reach the scene before EMS. Special first responder categories are more competitive and should be further investigated., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Background: Focused assessment sonography for trauma (FAST) performed in the prehospital setting may improve trauma care by influencing treatment decisions and reducing time to definitive care, but its accuracy and benefits remain uncertain. This systematic review evaluated the diagnostic accuracy of prehospital FAST in detecting hemoperitoneum and its effects on prehospital time and time to definitive diagnosis or treatment., Methods: We systematically searched PubMed, Embase, and Cochrane library up to November 11th, 2022. Studies investigating prehospital FAST and reporting at least one outcome of interest for this review were considered eligible. The primary outcome was prehospital FAST diagnostic accuracy for hemoperitoneum. A random-effect meta-analysis, including individual patient data, was performed to calculate the pooled outcomes with 95% confidence intervals (CI). Quality of studies was assessed using the QUADAS-2 tool for diagnostic accuracy., Results: We included 21 studies enrolling 5790 patients. The pooled sensitivity and specificity of prehospital FAST for hemoperitoneum were 0.630 (0.454 - 0.777) and 0.970 (0.957-0.979), respectively. Prehospital FAST was performed in a median of 2.72 (2.12 - 3.31) minutes without increasing prehospital times (pooled median difference of 2.44 min [95% CI: -3.93 - 8.81]) compared to standard management. Prehospital FAST findings changed on-scene trauma care in 12-48% of cases, the choice of admitting hospital in 13-71%, the communication with the receiving hospital in 45-52%, and the transfer management in 52-86%. Patients with a positive prehospital FAST achieved definitive diagnosis or treatment more rapidly (severity-adjusted pooled time ratio = 0.63 [95% CI: 0.41 - 0.95]) compared with patients with a negative or not performed prehospital FAST., Conclusions: Prehospital FAST had a low sensitivity but a very high specificity to identify hemoperitoneum and reduced time-to-diagnostics or interventions, without increasing prehospital times, in patients with a high probability of abdominal bleeding. Its effect on mortality is still under-investigated., Competing Interests: Declaration of competing interest LG, TS, MT, VC, CAM, CL, DA, CC, GG, and EB report no conflict of interest., (Copyright © 2023.

Physical inactivity is a plague for public health, especially in Western Countries. Among the countermeasures, mobile applications promoting physical activity seem particularly promising, thanks to the spread and adoption of mobile devices. However, the dropout rates of users are high, thereby calling for strategies to increase retention rates. Moreover, user testing can be problematic, because it is typically conducted in a laboratory, leading to a limited ecological validity. In the present research, we developed a custom mobile app to promote physical activity. Three versions of the app were implemented, each featuring a different pattern of gamification elements. Moreover, the app was designed to work as a self-managed experimental platform. A remote field study was conducted to investigate the effectiveness of the different versions of the app. Behavioral log data of physical activity and interaction with the app were collected. Our results show the feasibility of using a mobile app running on personal devices as an independently managed experimental platform. Moreover, we found that gamification elements per se do not ensure higher retention rates, rather it emerged that the richer combination of gamified elements was effective.

Introduction: Predicting hearing outcome in sudden sensorineural hearing loss (SSNHL) is challenging, as well as detecting the underlying pathomechanisms. SSNHL could be associated with vestibular damage since cochleo-vestibular structures share the same vascularization, along with being in close anatomical proximity. Whereas viral inflammations and autoimmune/vascular disorders most likely represent the involved aetiologies, early-stage Menière's disease (MD) can also present with SSNHL. Since an early treatment could beneficially influence hearing outcome, understanding the possible etiology plays a pivotal role in orienting the most appropriate treatment. We aimed to evaluate the extent of vestibular damage in patients presenting with SSNHL with or without vertigo, investigate the prognostic role of vestibular dysfunctions on hearing recovery and detect specific lesion patterns related to the underlying pathomechanisms., Methods: We prospectively evaluated 86 patients with SSNHL. Audio-vestibular investigation included pure-tone/speech/impedance audiometry, cervical/ocular-VEMPs, vHIT and video-Frenzel examination. White matter lesions (WML) were evaluated on brain-MRI. Patients were followed-up and divided into "SSNHL-no-vertigo," "SSNHL+vertigo" and "MD" subgroups., Results: Hearing was more impaired in "SSNHL+vertigo" patients who exhibited either down-sloping or flat-type audiograms, and was less impaired in "MD" where low frequencies were mostly impaired ( p < 0.001). Otolith receptors were more frequently involved than semicircular canals (SCs). Although the "SSNHL-no-vertigo" subgroup exhibited the lowest vestibular impairment ( p < 0.001), 52% of patients developed otolith dysfunctions and 72% developed nystagmus. Only "MD" subjects showed anterior SC impairment and upbeating spontaneous/positional nystagmus. They more frequently exhibited cervical-VEMPs frequency tuning ( p = 0.036) and ipsilesional spontaneous nystagmus ( p < 0.001). "SSNHL+vertigo" subjects presented with more frequently impaired cervical-VEMPs and posterior SC and with higher number of impaired receptors ( p < 0.001). They mainly exhibited contralesional spontaneous and vibration-induced nystagmus ( p < 0.05) and only they showed the highest WML score and "vascular" lesion patterns ( p < 0.001). Concerning the outcomes, hearing was better in "MD" and worse in "SSNHL+vertigo" ( p < 0.001). Hearing recovery was mostly affected by cervical-VEMPs impairment and the number of involved receptors ( p < 0.05). Patients with "vascular" lesion patterns presented with the highest HL degree and WML score ( p ≤ 0.001), while none of them exhibited a complete hearing recovery ( p = 0.026)., Conclusions: Our data suggest that vestibular evaluation in SSNHL can provide useful information on hearing recovery and underlying aetiologies., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Castellucci, Botti, Delmonte, Bettini, Lusetti, Brizzi, Ruberto, Gamberini, Martellucci, Malara, Armato, Renna, Ghidini and Bianchin.)

Among the plethora of instruments present in healthcare environments, the hospital bed is undoubtedly one of the most important for patients and caregivers. However, their design usually follows a top-down approach without considering end-users opinions and desires. Exploiting Human-centered design (HCD) permits these users to have a substantial role in the final product outcome. This study aims to empower caregivers to express their opinion about the hospital bed using a qualitative approach. For a holistic vision, we conducted six focus groups and six semi-structured interviews with nurses, nursing students, social-health operators and physiotherapists belonging to many healthcare situations. We then used thematic analysis to extract the themes that participants faced during the procedures, providing a comprehensive guide to designing the future electrical medical bed. These work results could also help overcome many issues that caregivers face during their everyday working life. Moreover, we identified the User Experience features that could represent the essential elements to consider.

Introduction: Data on out-of-hospital cardiac arrest (OHCA) is limited in Italy, and there has never been a comprehensive systematic appraisal of the available evidence. Therefore, this review aims to explore the incidence, characteristics, and outcome of OHCA in Italy., Methods: We systematically searched PubMed, Embase, Google Scholar, ResearchGate, and conference proceedings up to September 23, 2022. Studies investigating OHCA in Italy and reporting at least one outcome related to cardiac arrest were considered eligible. The primary outcome was survival at the longest follow-up available. Risk of bias was assessed using the Joanna Briggs Institute critical appraisal tool. A random-effects model proportion meta-analysis was performed to calculate the pooled outcomes with 95% confidence interval (CI)., Results: We included 42 studies (43,042 patients) from 13 of the 20 Italian regions published between 1995 and 2022. Only five studies were deemed to be at low risk of bias. The overall average incidences of OHCA attended by emergency medical services and with resuscitation attempted were 86 (range: 10-190) and 55 (range: 6-108) per 100,000 populations per year, respectively. Survival at the longest follow-up available was 9.0% (95% CI, 6.7-12%; 30 studies and 15,195 patients) in the overall population, 25% (95% CI, 21-30%; 16 studies and 2,863 patients) among patients with shockable rhythms, 28% (95% CI, 20-37%; 8 studies and 1,292 patients) among the Utstein comparator group. Favourable neurological outcome was 5.0% (95% CI, 3.6-6.6%; 16 studies and 9,675 patients). Return of spontaneous circulation was achieved in 19% (95% CI, 16-23%; 40 studies and 30,875 patients) of cases. Bystanders initiated cardiopulmonary resuscitation in 26% (95% CI, 21-32%; 33 studies and 23,491 patients) of cases but only in 3.2% (95% CI, 1.9-4.9%; 9 studies and 8,508 patients) with an automated external defibrillator. The mean response time was 10.2 (95% CI, 8.9-11.4; 25 studies and 23,997 patients) minutes., Conclusions: Survival after OHCA in Italy occurred in one of every ten patients. Bystanders initiated cardiopulmonary resuscitation in only one-third of cases, rarely with a defibrillator. Different areas of the country collected data, but an essential part of the population was not included. There was high heterogeneity and large variation in outcomes results and reporting, limiting the confidence in the estimates of incidence and outcome. Creating and maintaining a nationwide registry is a priority., (© 2022 The Authors.)

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare channelopathy involving cardiac calcium metabolism that often shows up at an early age with misleading clinical symptoms such as emotion or exercise-related syncope with a normal resting ECG, however, if misdiagnosed, CPVT can lead to cardiac arrest in children or young adults. We describe the case of a 27-year-old woman with several misdiagnosed syncopal episodes leading to out-of-hospital cardiac arrest (OHCA). Her previous medical history, combined with automatic external defibrillator records (AED) and clinical data, strongly suggested the diagnosis of CPVT. Thus beta blocker therapy was immediately started and targeted genetic test undertaken, revealing a previously unreported heterozygous variant in the ryanodine receptor-2 (RYR2) gene., Competing Interests: Declaration of Competing Interest None for authors., (Copyright © 2022 Elsevier Inc.

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. A multivariable logistic regression analysis was performed to find the factors associated with the decision to access ALS. A subgroup analysis was performed on patients with a predicted probability of ALS between 35% and 65%. The single physician's behaviour was compared to that predicted by the model taking into account the entire agency., Results: Age, location of event, bystander cardiopulmonary resuscitation and EMS-witnessed event were independent factors influencing physicians' choices about ALS. Non-medical OHCA, younger patients, less experienced physicians, presence of breath activity at the emergency call and a longer time for ALS arrival were more frequent among cases with an expected higher variability in behaviours with ALS. Significant variability was detected between physicians., Conclusions: Significant inter-physician variability in access to ALS could be present within the same EMS, especially among less experienced physicians, non-medical OHCA and in presence of signs of life during emergency call. This arbitrariness has been observed and should be properly addressed by EMS team members as it raises ethical issues regarding the disparity in treatment., (Copyright © 2022 Elsevier B.V.

Background: Prone positioning is a complex, time-consuming task, involving significant intensive care unit staff. The increased workload during the COVID-19 pandemic and the reduced staffing boosted the burden of intensive care unit nurses, which might have a negative impact on patients' safety and outcomes., Methods: Retrospective chart review, analysing the hourly distribution of pronation and supination procedures in mechanically ventilated critically ill patients during the first and the second wave of the COVID-19 pandemic (March 2020-May 2021)., Results: 303 procedures were analysed: 77 pronation manoeuvres out of 156 (49.3%) and 82 supination out of 147 (55.8%) were performed in dedicated time slots in the afternoon (15.30-19.00) and in the morning (9.30-12.30) shifts, when the nursing staff was increased. At least five healthcare providers performed pronation manoeuvres. Six device displacements were registered., Conclusions: Planning complex activities such as prone positioning needs an effective strategy to optimize nursing staff workload in the intensive care unit. This organization allowed to perform pronation cycles with a duration of at least 16 h, according to current clinical recommendations., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 Elsevier Ltd.

Purpose of Review: Technology is being increasingly implemented in the fields of cardiac arrest and cardiopulmonary resuscitation. In this review, we describe how recent technological advances have been implemented in the chain of survival and their impact on outcomes after cardiac arrest. Breakthrough technologies that are likely to make an impact in the future are also presented., Recent Findings: Technology is present in every link of the chain of survival, from prediction, prevention, and rapid recognition of cardiac arrest to early cardiopulmonary resuscitation and defibrillation. Mobile phone systems to notify citizen first responders of nearby out-of-hospital cardiac arrest have been implemented in numerous countries with improvement in bystanders' interventions and outcomes. Drones delivering automated external defibrillators and artificial intelligence to support the dispatcher in recognising cardiac arrest are already being used in real-life out-of-hospital cardiac arrest. Wearables, smart speakers, surveillance cameras, and artificial intelligence technologies are being developed and studied to prevent and recognize out-of-hospital and in-hospital cardiac arrest., Summary: This review highlights the importance of technology applied to every single step of the chain of survival to improve outcomes in cardiac arrest. Further research is needed to understand the best role of different technologies in the chain of survival and how these may ultimately improve outcomes., (Copyright © 2022 Wolters Kluwer Health, Inc.

Introduction: Major haemorrhage after injury is the leading cause of preventable death for trauma patients. Recent advancements in trauma care suggest damage control resuscitation (DCR) should start in the prehospital phase following major trauma. In Italy, Helicopter Emergency Medical Services (HEMS) assist the most complex injuries and deliver the most advanced interventions including DCR. The effect size of DCR delivered prehospitally on survival remains however unclear., Methods and Analysis: This is an investigator-initiated, large, national, prospective, observational cohort study aiming to recruit >500 patients in haemorrhagic shock after major trauma. We aim at describing the current practice of hypotensive trauma management as well as propose the creation of a national registry of patients with haemorrhagic shock., Primary Objective: the exploration of the effect size of the variation in clinical practice on the mortality of hypotensive trauma patients. The primary outcome measure will be 24 hours, 7-day and 30-day mortality. Secondary outcomes include: association of prehospital factors and survival from injury to hospital admission, hospital length of stay, prehospital and in-hospital complications, hospital outcomes; use of prehospital ultrasound; association of prehospital factors and volume of first 24-hours blood product administration and evaluation of the prevalence of use, appropriateness, haemodynamic, metabolic and effects on mortality of prehospital blood transfusions., Inclusion Criteria: age >18 years, traumatic injury attended by a HEMS team including a physician, a systolic blood pressure <90 mm Hg or weak/absent radial pulse and a confirmed or clinically likely diagnosis of major haemorrhage. Prehospital and in-hospital variables will be collected to include key times, clinical findings, examinations and interventions. Patients will be followed-up until day 30 from admission. The Glasgow Outcome Scale Extended will be collected at 30 days from admission., Ethics and Dissemination: The study has been approved by the Ethics committee 'Comitato Etico di Area Vasta Emilia Centro'. Data will be disseminated to the scientific community by abstracts submitted to international conferences and by original articles submitted to peer-reviewed journals., Trial Registration Number: NCT04760977., Competing Interests: Competing interests: JBH is a consultant with Cellphire, Hemostatics and Arsenal, is co-founder, co-CEO and on the Board of Directors of Decisio Health, on the Board of Directors of QinFlow, Zibrio and Oxyband and a co-inventor of the Junctional Emergency Tourniquet Tool.

Background: The role of prehospital focused assessment sonography for trauma (FAST) is still under debate and no definitive recommendations are available in actual guidelines, moreover, the availability of ultrasound machines in emergency medical services (EMS) is still inhomogeneous. On the other hand, time to definitive care is strictly related to survival in bleeding trauma patients. This study aimed at investigating if a positive prehospital FAST in abdominal trauma patients could have a role in reducing door-to-CT scan or door-to-operating room (OR) time., Methods: This retrospective observational study included all the patients affected by an abdominal trauma with an abdominal abbreviated injury score ≥ 2 and a spleen or liver injury admitted to Maggiore Hospital Carlo Alberto Pizzardi, a level 1 trauma centre between 2014 and 2019. Prehospital and emergency department (ED) clinical and laboratory variables were collected, as well as in-hospital times during the diagnostic and therapeutic pathways of these patients., Results: 199 patients were included in the final analysis. Of these, 44 had a prehospital FAST performed and in 27 of them, peritoneal free fluid was detected in the prehospital setting, while 128 out of 199 patients had a positive ED-FAST. Sensitivity was 62.9% (95% CI: 42.4%-80.6%) and specificity 100% (95% CI: 80.5% - 100%). Patients with a positive prehospital FAST reported a significantly lower door-to-CT or door-to-OR median time (46 vs 69 min, p < 0.001). Prehospital hypotension and Glasgow coma scale, first arterial blood lactate, ISS, age, positive prehospital and ED FAST were inserted in a stepwise selection for a multivariable Cox proportional regression hazards model. Only ISS and prehospital FAST resulted significantly associated with a reduction in the door-to-CT scan or door-to-operating theatre time in the multivariable model., Conclusion: Prehospital FAST information of intraperitoneal free fluid could significantly hasten door-to-CT scan or door-to-operating theatre time in abdominal trauma patients if established hospital response protocols are available., Level of Evidence: III, (Therapeutic / Care Management)., Competing Interests: Decleration of Competing Interest None., (Copyright © 2021 Elsevier Ltd.

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. Discrimination was assessed with the area under the ROC curve (AUROC), while the calibration belts were used for the comparison of observed versus expected ROSC rates. The AUROCs from our cohort and other validation cohorts were compared using a studentized range test., Results: The AUROC for the study population was 0.691, comparable to that described by previous validation studies. Despite an acceptable overall calibration, we found a poor calibration for asystole and low pROSC ranges in PEA and shockable rhythms. The model showed a good calibration for patients aged over 80, while no differences in performance were found when evaluating events before and after the implementation of 2015 ERC guidelines., Conclusions: Despite AUROC values being similar in different validation studies for RACA score, we suggest separating the different rhythms when assessing ROSC probability with the RACA score, especially for asystole., (© 2022 The Author(s).)
