AI Article Synopsis
- The study explored the relationship between Type D Personality (TDP) and prehospital delay time (PHT) in 256 acute myocardial infarction (AMI) patients in China, revealing how psychological traits influence health behaviors.
- Female patients with TDP experienced significantly shorter PHT compared to non-TDP females, while no such effect was observed in males.
- Negative affectivity (NA) was negatively correlated with PHT, indicating that emotional responses could impact decision-making during health emergencies, though this effect diminished when accounting for other psychological factors.
Article Abstract
Background: The Type D Personality (TDP) has been specifically linked to acute myocardial infarction (AMI). However, the impact on prehospital delay of AMI patients is unclear. The aim of this study was to assess the relationship between TDP and pre-hospital delay time (PHT) in a Chinese population.
Methods: A total of 256 AMI patients (47 women and 209 men) were taken from the Multicenter Delay in Patients Experiencing AMI in Shanghai (MEDEA FAR-EAST) study. Sociodemographic and psycho-behavioral characteristics were assessed by bedside interviews and questionnaires. TDP was evaluated according to the Type D Personality Scale (DS14) subdivided in social inhibition (SI) and negative affectivity (NA). Based on a significant interaction analysis of TDP and sex on PHT, all analyses were stratified by sex.
Results: PHT of female patients with TDP were substantially shorter compared to non-TDP female patients (108 281 min, P=0.029). In male patients, no effect of TDT on PHT was found. Spearman correlation analysis suggests that NA was negatively correlated with PHT (r=-0.358, P=0.014). Further age-adjusted logistic regression analyses showed that female patients with TDP were generally less likely to prehospital delay compared with non-TDP patients (OR =0.28; 95% CI, 0.08-0.98) and had a lower risk of PHT >360 minutes (OR =0.10; 95% CI, 0.01-0.91). However, statistical significance disappeared after adjustment for psychological factors (anxiety, depression, suboptimal wellbeing, cardiac denial and stress event).
Conclusions: TDP is associated with less prehospital delay in female patients during AMI-an effect which may be particularly mediated by NA.

Community-onset pediatric status epilepticus: Barriers to care and outcomes in a real-world setting.

Objective: Status epilepticus (SE) is a neurological emergency in childhood, often leading to neuronal damage and long-term outcomes. The study aims to identify barriers in the pre-hospital and in-hospital management of community-onset pediatric SE and to evaluate the effectiveness of pediatric scores on outcomes prediction.
Methods: This monocentric observational retrospective cohort study included patients treated for community-onset pediatric SE in a tertiary care hospital between 2010 and 2021.
Background: Despite decades of educational efforts, patients with acute ischemic stroke (AIS) remain delayed in seeking medical care, which becomes the greatest obstacle to the successful management of the condition.
Objective: To systematically explore the incidence and influencing factors of pre-hospital care-seeking delay in acute ischemic stroke patients.
Methods: We systematically searched the PubMed, Embase, Cochrane Library, Web of Science, and Cumulative Index to Nursing and Allied Health Literature from database inception to September 30, 2023.
Characterizing TIA and stroke symptomatology in a population-based study: implications for and diagnostic value of FAST-based public education.

Background: Urgent medical treatment is crucial after stroke and transient ischemic attack (TIA), but hindered by extensive prehospital delays. Public education campaigns based on FAST (Face-Arm-Speech-Time) have improved response after major stroke, but not minor stroke and TIA. We aimed to provide strategies to improve public education on a national level, by characterizing TIA and stroke symptoms in a population-based cohort, and extrapolating findings to the general Dutch population.

Background: Administering intravenous thrombolysis (IVT) as soon as possible after symptom onset impacts on the functional outcome for patients with acute ischaemic stroke. The study aimed to assess whether the distance from hospital impacts on the access to IVT for acute ischaemic stroke at the University Hospital of North Norway in Tromsø (UNN Tromsø).
Material And Method: This prospective quality study included 231 patients admitted with acute ischaemic stroke to UNN in the period 1 January 2019-31 December 2019.
Language barriers in emergency ambulance calls for cardiac arrest: Cases of missing vital information.

In medical emergencies, phoning the ambulance service constitutes a high-stakes interaction. Call-takers rely on callers to provide information about the patient so they can promptly recognise the medical problem and take swift action to remedy it. When a language barrier exists between the call-taker and caller, this can add a further challenge, given that third-party interpreters are rarely engaged, especially for time-critical conditions such as cardiac arrest.
