[PMID: 38920675 PMCID: PMC11201463 DOI: 10.3390/cells13121047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2024] [Revised: 05/30/2024] [Accepted: 06/07/2024] [Indexed: 06/27/2024] Open
Abstract
BACKGROUND Ischemic post-conditioning (IPoC) has been shown to improve outcomes in limited pre-clinical models. As down-time is often unknown, this technique needs to be investigated over a range of scenarios. As this tool limits reperfusion injury, there may be limited benefit or even harm after short arrest and limited ischemia-reperfusion injury. METHODS Eighteen male Wistar rats underwent 7 min of asphyxial arrest. Animals randomized to IPoC received a 20 s pause followed by 20 s of compressions, repeated four times, initiated 40 s into cardiopulmonary resuscitation. If return of spontaneous circulation (ROSC) was achieved, epinephrine was titrated to mean arterial pressure (MAP) of 70 mmHg. Data were analyzed using t-test or Mann-Whitney test. Significance set at p ≤ 0.05. RESULTS The rate of ROSC was equivalent in both groups, 88%. There was no statistically significant difference in time to ROSC, epinephrine required post ROSC, carotid flow, or peak lactate at any timepoint. There was a significantly elevated MAP with IPoC, 90.7 mmHg (SD 13.9), as compared to standard CPR, 76.7 mmHg (8.5), 2 h after ROSC, p = 0.03. CONCLUSIONS IPoC demonstrated no harm in a model of short arrest using a new arrest etiology for CPR based IPoC intervention in a rat model.

Abstract
BACKGROUND Out-of-hospital cardiac arrest (OHCA) is a leading cause of death worldwide. AIM To explore factors influencing prehospital return of spontaneous circulation (P-ROSC) in patients with OHCA and develop a nomogram prediction model. METHODS Clinical data of patients with OHCA in Shenzhen, China, from January 2012 to December 2019 were retrospectively analyzed. Least absolute shrinkage and selection operator (LASSO) regression and multivariate logistic regression were applied to select the optimal factors predicting P-ROSC in patients with OHCA. A nomogram prediction model was established based on these influencing factors. Discrimination and calibration were assessed using receiver operating characteristic (ROC) and calibration curves. Decision curve analysis (DCA) was used to evaluate the model's clinical utility. RESULTS Among the included 2685 patients with OHCA, the P-ROSC incidence was 5.8%. LASSO and multivariate logistic regression analyses showed that age, bystander cardiopulmonary resuscitation (CPR), initial rhythm, CPR duration, ventilation mode, and pathogenesis were independent factors influencing P-ROSC in these patients. The area under the ROC was 0.963. The calibration plot demonstrated that the predicted P-ROSC model was concordant with the actual P-ROSC. The good clinical usability of the prediction model was confirmed using DCA. CONCLUSION The nomogram prediction model could effectively predict the probability of P-ROSC in patients with OHCA.

Abstract
Background Traumatic retropharyngeal hematoma followed by airway obstruction is extremely rare. In this report, we show unique images from two cases of out-of-hospital cardiac arrest due to airway obstruction caused by massive retropharyngeal hematoma after a minor facial injury. Case presentation Case 1: A 78-year-old man was transferred to our emergency department due to cardiac arrest. He presented with respiratory insufficiency after a ground level fall. His neck was swollen, and the attending physician performed an emergent cricothyroidotomy to secure his airway and administered intravenous adrenaline. Computed tomography revealed a massive retropharyngeal hematoma and severe hypoxic encephalopathy. Despite a temporary return of spontaneous circulation (ROSC), the patient died on the admission day.Case 2: A 68-year-old woman presented with dyspnea, prompting her family to call an ambulance. On the way to the hospital, the ambulance crew determined the patient was in cardiac arrest. The patient's history revealed a ground level fall in which she hit her face. Computed tomography revealed a massive retropharyngeal hematoma compressing her upper airway. Although ROSC was obtained, the patient died on the 12th day of hospitalization due to hypoxic encephalopathy.Extension views of cervical spine images identified angular instability without cervical bone fracture in both cases, suggesting that possible injuries of the anterior longitudinal ligament contributed to the retropharyngeal hematoma. Conclusions Patients presenting with asphyxia after a simple ground level fall accompanied by minor facial injuries should be assessed by emergency physicians for the possibility of a retropharyngeal hematoma. In both cases presented here, unique images indicate possible injuries of the anterior longitudinal ligament.

Abstract
AIMS The risk, characteristics, and outcome of out-of-hospital cardiac arrest (OHCA) in patients with congenital heart disease (CHD) remain scarcely investigated. METHODS AND RESULTS An epidemiological registry-based study was conducted. Using time-dependent Cox regression models fitted with a nested case-control design, hazard ratios (HRs) with 95% confidence intervals of OHCA of presumed cardiac cause (2001-19) associated with simple, moderate, and severe CHD were calculated. Moreover, using multiple logistic regression, we investigated the association between pre-hospital OHCA characteristics and 30-day survival and compared 30-day survival in OHCA patients with and without CHD. Overall, 43 967 cases (105 with simple, 144 with moderate, and 53 with severe CHD) and 219 772 controls (median age 72 years, 68.2% male) were identified. Any type of CHD was found to be associated with higher rates of OHCA compared with the background population [simple CHD: HR 1.37 (1.08-1.70); moderate CHD: HR 1.64 (1.36-1.99); and severe CHD: HR 4.36 (3.01-6.30)]. Pre-hospital cardiopulmonary resuscitation and defibrillation were both associated with improved 30-day survival in patients with CHD, regardless of CHD severity. Among patients with OHCA, simple, moderate, and severe CHD had a similar likelihood of 30-day survival compared with no CHD [odds ratio 0.95 (0.53-1.69), 0.70 (0.43-1.14), and 0.68 (0.33-1.57), respectively]. CONCLUSION A higher risk of OHCA was found throughout the spectrum of CHD. Patients with and without CHD showed the same 30-day survival, which relies on the pre-hospital chain of survival, namely cardiopulmonary resuscitation and defibrillation.

Outcomes after out-of-hospital cardiac arrest in immigrants vs natives in Denmark. Resuscitation 2023; 190:109872. [PMID: 37327849 DOI: 10.1016/j.resuscitation.2023.109872] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Revised: 06/05/2023] [Accepted: 06/07/2023] [Indexed: 06/18/2023]
Abstract
AIMS Ethnic disparities subsist in out-of-hospital cardiac arrest (OHCA) outcomes in the US, yet it is unresolved whether similar inequalities exist in European countries. This study compared survival after OHCA and its determinants in immigrants and non-immigrants in Denmark. METHODS Using the nationwide Danish Cardiac Arrest Register, 37,622 OHCAs of presumed cardiac cause between 2001 and 2019 were included, 95% in non-immigrants and 5% in immigrants. Univariate and multiple logistic regression was used to assess disparities in treatments, return of spontaneous circulation (ROSC) at hospital arrival, and 30-day survival. RESULTS Immigrants were younger at OHCA (median 64 [IQR 53-72] vs 68 [59-74] years; p < 0.05), had more prior myocardial infarction (15% vs 12%, p < 0.05), more diabetes (27% vs 19%, p < 0.05), and were more often witnessed (56% vs 53%; p < 0.05). Immigrants received similar bystander cardiopulmonary resuscitation and defibrillation rates to non-immigrants, but more coronary angiographies (15% vs 13%; p < 0.05) and percutaneous coronary interventions (10% vs 8%, p < 0.05), although this was insignificant after age-adjustment. Immigrants had higher ROSC at hospital arrival (28% vs 26%; p < 0.05) and 30-day survival (18% vs 16%; p < 0.05) compared to non-immigrants, but adjusting for age, sex, witness status, first observed rhythm, diabetes, and heart failure rendered the difference non-significant (odds ratios (OR) 1.03, 95% confidence interval (CI) 0.92-1.16 and OR 1.05, 95% CI 0.91-1.20, respectively). CONCLUSIONS OHCA management was similar between immigrants and non-immigrants, resulting in similar ROSC at hospital arrival and 30-day survival after adjustments.

Abstract
BACKGROUND Data on out-of-hospital cardiac arrest are still scarce, very varied, and indicate a poor prognosis for traumatic events. OBJECTIVES To describe the out-of-hospital/in-hospital survival, survival time, and neurological conditions of those treated by advanced life support units and submitted to cardiopulmonary resuscitation and compare the results of clinical and traumatic cardiac arrests. METHODS This is a cohort study carried out in three stages; in the first two, data were collected from the Mobile Emergency Care Service forms and medical records; then, the Brain Performance Category Scale was applied in the third stage. The sample consisted of resuscitated victims aged ≥18 years. Fisher's and log-rank tests were used to compare the causes, considering a significance level of 5%. RESULTS 852 patients were analyzed; 20.66% were hospitalized, 4.23% survived until transfer or discharge, and 58.33% had a favorable outcome one year after arrest. There was an association between pre/in-hospital survival and the nature of the occurrence (p=0.026), but there was no difference between the survival curves (p=0.6). CONCLUSIONS Survival of hospitalization after out-of-hospital cardiac arrest was low; however, most who survived to be discharged achieved a favorable outcome after one year. The survival time of those hospitalized after clinical and traumatic events were similar, but pre-hospital survival was higher among trauma patients.

Abstract
BACKGROUND Out-of-hospital cardiac arrest (OHCA) remains a health problem worldwide, carrying a high mortality rate. Comparison of emergency department (ED) return of spontaneous circulation (ROSC) after OHCA in relation to emergency medical services (EMS) and non-EMS modes of transportation to the hospital was conducted to assess the impact points of the EMS system in Thailand. METHODS This retrospective observational study enrolled all OHCA patients who visited the ED of Ramathibodi Hospital, a tertiary university hospital in Bangkok, between January 1, 2008, and May 31, 2020. Patients were differentiated into EMS and non-EMS groups according to mode of transportation to the ED. Patients' characteristics and comorbidities, witnessed arrests, bystander chest compression, initial rhythm, and resuscitation treatment were documented. ED-sustained ROSC, ED survival, 30-day survival, and 30-day survival with good cerebral performance category (CPC) scores were monitored and recorded. Multivariate logistic analyses were performed to assess factors influencing clinical outcomes. RESULTS A total of 339 patients were enrolled, 117 (34.51%) of whom were in the EMS transport group. There were no differences between the EMS and non-EMS groups in ED-sustained ROSC (adjusted odds ratio [aOR], 0.99; 95% confidence interval [CI], 0.58-1.70; P = 0.98), or ED survival (aOR, 0.99; 95% CI, 0.57-1.71; P = 0.97). There were also no differences in 30-day survival or 30-day survival with good CPC score between the two groups. CONCLUSIONS In our cohort data of OHCA, ED-sustained ROSC and ED survival outcomes were not superior in the EMS transportation group. Evidence to show that EMS transportation affected 30-day survival and 30-day good CPC score was also lacking. Thus, public promotion of Thailand's EMS system is advocated with a simultaneous improvement of EMS response to enhance OHCA outcomes.

External validation of the simple NULL-PLEASE clinical score in predicting outcomes of out-of-hospital cardiac arrest in the Danish population - A nationwide registry-based study.

Abstract
AIM The NULL-PLEASE score (Nonshockable rhythm, Unwitnessed arrest, Long no-flow or Long low-flow period, blood pH < 7.2, Lactate > 7.0 mmol/L, End-stage renal disease on dialysis, Age ≥85 years, Still resuscitation, and Extracardiac cause) may identify patients with out-of-hospital cardiac arrest (OHCA) unlikely to survive. We aimed to validate the NULL-PLEASE score in a nationwide setting. METHODS We used Danish nationwide registry data from 2001 to 2019 and identified OHCA survivors with return of spontaneous circulation (ROSC) or ongoing cardiopulmonary resuscitation at hospital arrival. The primary outcome was 1-day mortality. Secondary outcomes were 30-day mortality and the combined outcome of 1-year mortality or anoxic brain damage. The risks of outcomes were estimated using logistic regression with a NULL-PLEASE score of 0 as reference (range 0-14). The predictive ability of the score was examined using the area under the receiver operating characteristics (AUCROC) curve. RESULTS A total of 3,881 patients were included in the analyses. One-day mortality was 35%, 30-day mortality was 61%, and 68% experienced the combined outcome. For a NULL-PLEASE score ≥9 (n = 244) the absolute risks were: 1-day mortality: 80.7% (95% confidence interval [CI]: 75.8-85.7%); 30-day mortality: 98.0% (95% CI: 96.2-99.7%); and the combined outcome: 98.4% (95% CI: 96.8-100.0%). Corresponding AUCROC values were 0.800 (95% CI: 0.786-0.814) for 1-day mortality, 0.827 (95% CI: 0.814-0.840) for 30-day mortality, and 0.828 (95% CI: 0.815-0.841) for the combined outcome. CONCLUSIONS In a nationwide OHCA-cohort, AUCROC values for the predictive ability of NULL-PLEASE were high for all outcomes. However, some survived even with high NULL-PLEASE scores.

Moll-Khosrawi P, Falb A, Pinnschmidt H, Zöllner C, Issleib M. Virtual reality as a teaching method for resuscitation training in undergraduate first year medical students during COVID-19 pandemic: a randomised controlled trial. BMC MEDICAL EDUCATION 2022; 22:483. [PMID: 35733135 PMCID: PMC9214467 DOI: 10.1186/s12909-022-03533-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Accepted: 06/03/2022] [Indexed: 05/30/2023]
Abstract
BACKGROUND Virtual reality (VR) is a computer-generated simulation technique which yields plenty of benefits and its application in medical education is growing. This study explored the effectiveness of a VR Basic Life Support (BLS) training compared to a web-based training during the COVID-19 pandemic, in which face-to-face trainings were disrupted or reduced. METHODS This randomised, double-blinded, controlled study, enrolled 1st year medical students. The control group took part in web-based BLS training, the intervention group received an additional individual VR BLS training. The primary endpoint was the no-flow time-an indicator for the quality of BLS-, assessed during a structural clinical examination, in which also the overall quality of BLS (secondary outcome) was rated. The tertiary outcome was the learning gain of the undergraduates, assessed with a comparative self-assessment (CSA). RESULTS Data from 88 undergraduates (n = 46 intervention- and n = 42 control group) were analysed. The intervention group had a significant lower no-flow time (p = .009) with a difference between the two groups of 28% (95%-CI [8%;43%]). The overall BLS performance of the intervention group was also significantly better than the control group with a mean difference of 15.44 points (95%-CI [21.049.83]), p < .001. In the CSA the undergraduates of the intervention group reported a significant higher learning gain. CONCLUSION VR proved to be effective in enhancing process quality of BLS, therefore, the integration of VR into resuscitation trainings should be considered. Further research needs to explore which combination of instructional designs leads to deliberate practice and mastery learning of BLS.

Globally, GDP Per Capita Correlates Strongly with Rates of Bystander CPR. Ann Glob Health 2022; 88:36. [PMID: 35651970 PMCID: PMC9138810 DOI: 10.5334/aogh.3624] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Accepted: 05/03/2022] [Indexed: 11/27/2022] Open
Abstract
Introduction: Bystander CPR is vital in improving outcomes for out-of-hospital cardiac arrest. There has been ample literature describing disparities in bystander CPR within specific countries, such as the United States, Australia, and the Netherlands. However, there has not been significant literature describing such disparities between countries. Methods: We examined various studies published between 2000 and 2021 that reported rates of bystander CPR in various countries. These bystander CPR rates were correlated with the GDP per capita of that country during the time the study was conducted. The correlation between GDP per capita and rates of bystander CPR was assessed. Results: A total of 29 studies in 35 communities across 25 countries were examined. Reported rates of bystander CPR ranged from 1.3% to 72%. From this, a strong and significant correlation between GDP per capita and rates of bystander CPR was apparent; 0.772 (p < .01), r2 = 0.596. Conclusions: GDP per capita can be thought of as a composite endpoint that takes into account various aspects of a country’s social and economic well-being. Socioeconomically-advantaged communities likely have a better ability to provide CPR education to community members, and our findings mirror localized analyses comparing socioeconomic status and rates of bystander CPR. Future studies should continue to elucidate transnational disparities in cardiac arrest, and efforts should be directed at providing CPR education to communities with low rates of bystander CPR; low-and-middle-income countries may represent attractive targets for such interventions. However, it may be possible that rates of bystander CPR may not improve unless significant upstream improvements to socioeconomic factors take place.

Outcomes of prolonged dual anti-platelet therapy in patients with acute coronary syndrome undergoing percutaneous coronary intervention: A nationwide registry-based study. Am Heart J 2022; 245:81-89. [PMID: 34902311 DOI: 10.1016/j.ahj.2021.11.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Revised: 09/29/2021] [Accepted: 11/20/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND Randomized controlled trials have shown a reduced risk of ischemic events and an increased risk of bleeding in patients treated with prolonged dual anti-platelet therapy (DAPT) beyond 12 months following acute coronary syndrome (ACS). We aimed to investigate outcomes of prolonged DAPT vs aspirin monotherapy (ASA) in a real-world population. METHODS AND RESULTS Using nationwide registries, we identified all patients with ACS who underwent percutaneous coronary intervention and received 12-month DAPT between January 2013 and October 2016. Patients still on DAPT were compared to patients on ASA at index date (15 months after ACS-date) and followed for up to 2 years. Cox regression models were employed to calculate standardized risks of all-cause mortality, major adverse cardiovascular event (MACE), and major bleeding. The study included 7,449 patients, 1,901 on DAPT (median age 66, 72.1% male) and 5,548 on ASA (median age 65, 75.1% male). Standardized absolute 2-year risk of all-cause mortality, MACE, and major bleeding was 2.7%, 3.7%, and 5.4% for DAPT vs 2.2%, 3.8%, and 1.3% for ASA. DAPT was not associated with a significant standardized 2-year risk difference (SRD) of all-cause mortality (SRD: 0.5%, 95% confidence interval [CI]: -0.9 to 1.7) or MACE (SRD: -0.1%, 95% CI -1.8 to 1.6), but a significantly higher risk of major bleeding (SRD: 4.1%, 95% CI 1.8-6.6). CONCLUSIONS In a nationwide cohort of ACS patients undergoing percutaneous coronary intervention, prolonged DAPT was not significantly associated with a reduced risk of all-cause mortality or MACE, but an increased risk of major bleeding. Future randomized controlled trials should investigate the optimal anti-platelet regimen in this patient group.

Abstract
Background It remains challenging to identify patients at risk of out-of-hospital cardiac arrest (OHCA). We aimed to examine health care contacts in patients before OHCA compared with the general population that did not experience an OHCA. Methods and Results Patients with OHCA with a presumed cardiac cause were identified from the Danish Cardiac Arrest Registry (2001-2014) and their health care contacts (general practitioner [GP]/hospital) were examined up to 1 year before OHCA. In a case-control study (1:9), OHCA contacts were compared with an age- and sex-matched background population. Separately, patients with OHCA were examined by the contact type (GP/hospital/both/no contact) within 2 weeks before OHCA. We included 28 955 patients with OHCA. The weekly percentages of patient contacts with GP the year before OHCA were constant (25%) until 1 week before OHCA when they markedly increased (42%). Weekly percentages of patient contacts with hospitals the year before OHCA gradually increased during the last 6 months (3.5%-6.6%), peaking at the second week (6.8%) before OHCA; mostly attributable to cardiovascular diseases (21%). In comparison, there were fewer weekly contacts among controls with 13% for GP and 2% for hospital contacts (P<0.001). Within 2 weeks before OHCA, 57.8% of patients with OHCA had a health care contact, and these patients had more contacts with GP (odds ratio [OR], 3.17; 95% CI, 3.09-3.26) and hospital (OR, 2.32; 95% CI, 2.21-2.43) compared with controls. Conclusions The health care contacts of patients with OHCA nearly doubled leading up to the OHCA event, with more than half of patients having health care contacts within 2 weeks before arrest. This could have implications for future preventive strategies.

Opioid use is associated with increased out-of-hospital cardiac arrest risk among 40 000-cases across two countries. Br J Clin Pharmacol 2021; 88:2256-2266.

Abstract
Aims Opioid use has substantially increased in the last decade and is associated with overdose mortality, but also with increased mortality from cardiovascular causes. This finding may partly reflect an association between opioids and out‐of‐hospital cardiac arrest (OHCA). Therefore, we aimed to investigate OHCA‐risk of opioids in the community. Methods We conducted 2 population‐based case–control studies separately in the Netherlands (2009–2018) and Denmark (2001–2015). Cases were individuals who experienced OHCA of presumed cardiac cause. Each case was matched with up to 5 non‐OHCA‐controls according to age, sex and OHCA‐date. Conditional logistic regression analysis was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs). Results We included 5473 OHCA‐cases matched with 21 866 non‐OHCA‐controls in the Netherlands, and 35 017 OHCA‐cases matched with 175 085 non‐OHCA‐controls in Denmark. We found that use of opioids (the Netherlands: cases: 5.4%, controls: 1.8%; Denmark: cases: 11.9%, controls: 4.4%) was associated with increased OHCA‐risk in both regions (the Netherlands: OR 2.1 [95% CI 1.8–2.5]; Denmark: OR 1.8 [95% CI 1.5–2.1]). The association was observed in both sexes, and in individuals with cardiovascular disease (the Netherlands: OR 1.8 [95% CI 1.5–2.1]; Denmark: OR 1.6 [95% CI 1.5–1.7]) or without (the Netherlands: OR 3.4 [95% CI: 2.4–4.8], Pinteraction < .0001; Denmark: OR 2.3 [95% CI: 2.0–2.5], Pinteraction < .0001). Conclusion Use of opioids is associated with increased OHCA‐risk in both sexes, independently of concomitant cardiovascular disease. These findings should be considered when evaluating the harms and benefits of treatment with opioids.

Abstract
Societal lockdowns during the first wave of the coronavirus disease 2019 pandemic were associated with decreased admission rates for acute cardiovascular conditions worldwide. In this nationwide Danish study of the first five weeks of a second pandemic lockdown, incidence of new-onset heart failure and atrial fibrillation remained stable, but there was a significant drop in new-onset ischemic heart disease and ischemic stroke during the fourth week of lockdown, which normalized promptly. The observed drops were lower compared to the first Danish lockdown in March 2020; thus, our data suggest that declines in acute cardiovascular disease admission rates during future lockdowns are avoidable.

Blood Cultures and Appropriate Antimicrobial Administration after Achieving Sustained Return of Spontaneous Circulation in Adults with Nontraumatic Out-of-Hospital Cardiac Arrest. Antibiotics (Basel) 2021; 10:antibiotics10070876. [PMID: 34356797 PMCID: PMC8300804 DOI: 10.3390/antibiotics10070876] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Revised: 07/12/2021] [Accepted: 07/13/2021] [Indexed: 11/17/2022] Open
Abstract
We aimed to determine the incidence of bacteremia and prognostic effects of prompt administration of appropriate antimicrobial therapy (AAT) on nontraumatic out-of-hospital cardiac arrest (OHCA) patients achieving a sustained return of spontaneous circulation (sROSC), compared with non-OHCA patients. In the multicenter case-control study, nontraumatic OHCA adults with bacteremia episodes after achieving sROSC were defined as case patients, and non-OHCA patients with community-onset bacteremia in the emergency department were regarded as control patients. Initially, case patients had a higher bacteremia incidence than non-OHCA visits (231/2171, 10.6% vs. 10,430/314,620, 3.3%; p < 0.001). Compared with the matched control (2288) patients, case (231) patients experienced more bacteremic episodes due to low respiratory tract infections, fewer urosepsis events, fewer Escherichia coli bacteremia, and more streptococcal and anaerobes bacteremia. Antimicrobial-resistant organisms, such as methicillin-resistant Staphylococcus aureus and extended-spectrum beta-lactamase-producing Enterobacteriaceae, were frequently evident in case patients. Notably, each hour delay in AAT administration was associated with an average increase of 10.6% in crude 30-day mortality rates in case patients, 0.7% in critically ill control patients, and 0.3% in less critically ill control patients. Conclusively, the incidence and characteristics of bacteremia differed between the nontraumatic OHCA and non-OHCA patients. The incorporation of blood culture samplings and rapid AAT administration as first-aids is essential for nontraumatic OHCA patients after achieving sROSC.

Abstract
The authors report five forensic autopsy cases involving individuals who experienced cardiopulmonary arrest immediately after sustaining minor head injuries. Heartbeat was restored in two patients after resuscitation by paramedics. During autopsy, three patients exhibited high blood alcohol levels indicating severe intoxication, two had an unknown blood alcohol status, and all five exhibited parietal bruising of the head. In addition to alcohol intoxication, blunt force impact to the parietal area of the head was believed to be related to the occurrence of cardiopulmonary arrest immediately after head trauma. The absence of secondary brain damage in patients who die from cardiopulmonary arrest immediately after head trauma should be taken into account when diagnosing the cause of death. Additionally, indications for bystander cardiopulmonary resuscitation should be considered for individuals who experience cardiopulmonary arrest due to head trauma.

Abstract
OBJECTIVE Patients with bipolar disorder and schizophrenia are at high cardiovascular risk; yet, the risk of out-of-hospital cardiac arrest (OHCA) compared with the general population remains scarcely investigated. METHODS We conducted a nested case-control study using Cox regression to assess the association of bipolar disorder and schizophrenia with the HRs of OHCA of presumed cardiac cause (2001-2015). Reported are the HRs with 95% CIs overall and in subgroups defined by established cardiac disease, cardiovascular risk factors and psychotropic drugs. RESULTS We included 35 017 OHCA cases and 175 085 age-matched and sex-matched controls (median age 72 years and 66.9% male). Patients with bipolar disorder or schizophrenia had overall higher rates of OHCA compared with the general population: HR 2.74 (95% CI 2.41 to 3.13) and 4.49 (95% CI 4.00 to 5.10), respectively. The association persisted in patients with both cardiac disease and cardiovascular risk factors at baseline (bipolar disorder HR 2.14 (95% CI 1.72 to 2.66), schizophrenia 2.84 (95% CI 2.20 to 3.67)) and among patients without known risk factors (bipolar disorder HR 2.14 (95% CI 1.09 to 4.21), schizophrenia HR 5.16 (95% CI 3.17 to 8.39)). The results were confirmed in subanalyses only including OHCAs presenting with shockable rhythm or receiving an autopsy. Antipsychotics-but not antidepressants, lithium or antiepileptics (the last two only tested in bipolar disorder)-increased OHCA hazard compared with no use in both disorders. CONCLUSIONS Patients with bipolar disorder or schizophrenia have a higher rate of OHCA compared with the general population. Cardiac disease, cardiovascular risk factors and antipsychotics represent important underlying mechanisms.

Background EVapp (Emergency Volunteer Application) is a Belgian smartphone application that mobilizes volunteers to perform cardiopulmonary resuscitation (CPR) and defibrillation with publicly available automatic external defibrillators (AED) after an emergency call for suspected out of hospital cardiac arrest (OHCA). The aim is to bridge the time before the arrival of the emergency services. Methods An accessible model was developed, using literature data, to simulate survival and cost-effectiveness of nation-wide EVapp implementation. Initial validation was performed using field data from a first pilot study of EVapp implementation in a city in Flanders, covering 2.5 years of implementation. Results Simulation of nation-wide EVapp implementation resulted in an additional yearly 910 QALY gained over the current baseline case scenario (worst case 632; best case 3204). The cost per QALY associated with EVapp implementation was comparable to the baseline scenario, i.e., 17 vs 18 k€ QALY−1. Conclusions EVapp implementation was associated with a positive balance on amount of QALY gained and cost of QALY. This was a consequence of both the lower healthcare costs for patients with good neurological outcome and the more efficient use of yet available resources, which did not outweigh the costs of operation.
