Background: Basic life support (BLS) is a life-saving link in the out-of-hospital cardiac arrest chain of survival. Most members of the public are capable of providing BLS but are more likely to do so confidently and effectively if they undertake BLS training. Lay members of the public comprise diverse and specific populations and may benefit from tailored BLS training. Data on this topic are scarce, and it is completely unknown if there are any benefits arising from tailored courses or for whom course adaptations should be developed. Methods: The primary objective of this scoping review was to identify and describe differences in patient, clinical, and educational outcomes when comparing tailored versus standard BLS courses for specific layperson populations. This review was undertaken as part of the continuous evidence evaluation process of the International Liaison Committee on Resuscitation. Results: A primary search identified 1307 studies and after title, abstract, and full-text screening, we included eight publications reporting on tailored courses for specific populations. There were no studies reporting direct comparisons between tailored and standardized training. Seven (88%) studies investigated courses tailored for individuals with a disability, and only one study covered another specific population group (refugees). Overall, the quality of evidence was low as the studies did not compare tailored vs. non-tailored approaches or consisted of observational or pre–post-designed investigations. Conclusions: Tailored BLS education for specific populations is likely feasible and can include such groups into the pool of potential bystander resuscitation providers. Research into comparing tailored vs. standard courses, their cost-to-benefit ratio, how to best adapt courses, and how to involve members of the respective communities should be conducted. Additionally, tailored courses for first responders with and without a duty to respond could be explored.

Background Cardiopulmonary resuscitation (CPR) manikins typically appear white, lean and male. However, internationally, this does not represent the overall population or those who are at greatest risk of cardiac arrest. Diverse demographic groups including people of colour, women and obese people are known to be less likely to receive bystander CPR, public access defibrillation and suffer less favourable outcomes. It is plausible that failure to represent women, racially diverse and non-lean manikins can contribute to poor clinical outcomes in these populations. The aim of this scoping review was to summarise the current evidence for adaptations of manikins used for layperson Basic Life Support (BLS) training. Methods We searched MEDLINE, Embase, PsycINFO, CINAHL, ERIC, Web of Science, Infromit, Scopus and Cochrane Central Register of Controlled Trials to identify all empirical studies describing or evaluating CPR manikin diversity. Data on participant characteristics, manikin adaptations, study design, and key findings of included studies describing or evaluating CPR manikin diversity were extracted. Results Initially, 2719 studies were identified, and 15 studies were finally included and were grouped into (1) studies analysing adaptions of ‘standard’ manikins used in training (n=11) and (2) studies evaluating CPR manikin diversity used for online learning and on social media (n=4). Six of the studies analysing different adaptations reported the influence of the manikins’ sex on comfort in performing CPR, quality of chest compression, automated external defibrillator use and removing clothes; four the effects of obese manikins; and one an ethnically diverse manikin. Seven of the studies used do-it-yourself adaptions. Racial and gender diversity of CPR manikins found in educational videos was limited, with only 5% of educational videos featuring non-white manikins and 1% featuring female manikins. Conclusion Adaptations of manikins used for BLS CPR training for laypersons still do not represent the diversity of communities most people are living in, internationally. There are hints that using diverse racial manikins has the potential to improve engagement in CPR training. Reported barriers hindering the use of adapted manikins were high costs and availability of these manikins.

Background: The highly β1-selective beta-blocker Landiolol is known to facilitate efficient and safe rate control in non-compensatory tachycardia or dysrhythmia when administered continuously. However, efficacy and safety data of the also-available bolus formulation in critically ill patients are scarce. Methods: We conducted a retrospective cross-sectional study on a real-life cohort of critical care patients, who had been treated with push-dose Landiolol due to sudden-onset non-compensatory supraventricular tachycardia. Continuous hemodynamic data had been acquired via invasive blood pressure monitoring. Results: Thirty patients and 49 bolus applications were analyzed. Successful heart rate control was accomplished in 20 (41%) cases, rhythm control was achieved in 13 (27%) episodes, and 16 (33%) applications showed no effect. Overall, the heart rate was significantly lower (145 (130–150) vs. 105 (100–125) bpm, p < 0.001) in a 90 min post-application observational period in all subgroups. The median changes in blood pressure after the bolus application did not reach clinical significance. Compared with the ventilation settings before the bolus application, the respiratory settings including the required FiO₂ after the bolus application did not differ significantly. No serious adverse events were seen. Conclusions: Push-dose Landiolol was safe and effective in critically ill ICU patients. No clinically relevant impact on blood pressure was noted.

Background and Objectives: Cardiovascular diseases are prevalent entities, especially in emergency patients. Arterial stiffness is a known predictor of cardiovascular risk and mortality and is quantified by carotid-femoral pulse wave velocity (cfPWV). It is caused in part by vascular calcification, but exact details of the underlying mechanisms are yet to be elucidated, and current data suggest endocrine influences. This study thus aimed to assess the associations of endocrine parameters, particularly thyroid and parathyroid hormones, calcium, inorganic phosphate, and vitamin D, with cfPWV as a surrogate for arterial stiffness. Materials and Methods: Adults presenting to a single tertiary care emergency department in Vienna between 2018 and 2023 were prospectively enrolled. CfPWV was measured non-invasively, and levels of thyroid and parathyroid hormones and 25-hydroxyvitamin D, calcium, and inorganic phosphate were assessed. Results: In total, data from 827 patients, predominantly male (57%) and around 60 (47–72) years of age, were assessed. We observed a significant worsening of cfPWV with increasing parathyroid hormone levels (p < 0.001) and TSH levels (p = 0.03). No significant influences of calcium, inorganic phosphate, or 25-hydroxyvitamin D were observed. Conclusions: Thyroid and parathyroid hormone levels are associated with arterial stiffness in emergency department patients, suggesting a need for a comprehensive workup in patients at risk because of comorbidities and age. Additional prospective studies are needed to further elucidate the role of endocrinology in arterial stiffness and the subsequent relevance in emergency medicine.

Background: Long-distance running impacts many organ systems. Aside from musculoskeletal and cardiopulmonary events, the gastrointestinal and renal system as well as metabolic homeostasis and electrolyte balance can be affected. A respective medical support strategy enabling rapid diagnosis, triage, and treatment in the context of large sports events is thus of utmost importance. Incidents can be assessed and graded via point-of-care (POC) blood gas analysis (BGA). We thus aimed to evaluate the feasibility and benefits of its use during a large sports event. Methods: All documented patient contacts during the race of the Vienna City Marathon (VCM) 2023 were retrospectively assessed. Additionally, the BGAs conducted in all patients requiring intravenous access were analyzed. Data are presented in a descriptive manner. Results: There were 39,871 participants at the VCM 2023. Of these, 277 (0.7%) required medical support, localized most commonly in the finishing area of the race (n = 239, 86% of all incidents). Fifty-eight (20.9%) patients had to be hospitalized. The most frequent chief complaints were syncope or collapse (24.9%), followed by general pain (20.6%) and trauma (14.8%). Five patients (1.8%) suffered from seizures, and one experienced (0.4%) from spontaneous pneumothorax. Thirty-one patients (11.2%) received venous blood gas analyses, showing mean creatinine levels of 1.82 (±0.517) mg/dL, mean lactate concentrations of 6.03 (±4.5) mmol/L, mean pH of 7.42 (±0.0721), and a mean base excess of −0.72 (±3.72) mmol/L. No cases of hyponatremia occurred in the documented samples. In eight cases (25.8%), sodium concentrations were above 145 mmol/L, with a maximum of 149 mmol/L. No cardiac arrests occurred. Conclusions: The physical exertion during the assessed long-distance running race resulted in numerous contacts with the medical support teams. The use of POC BGA at a large-scale marathon event was shown to be easy and feasible, allowing for more extensive diagnostics on-site. It can be integrated into a medical support strategy and might be beneficial for decision-making regarding patient triage, treatment, hospitalization, or patient discharge.
