Introduction: pulmonary embolism is a real public health problem because of its high morbidity and mortality rate. The purpose of this study is to evaluate the impact of PESI score on the prognosis of pulmonary embolism.
Methods: we conducted a retrospective study of 146 cases of formally confirmed embolism. Pulmonary embolism severity index (PESI) score was calculated for the entire study population. The patients were divided into 2 groups: a low-risk group (LR) comprising patients in risk classes I and II: 83 patients; a high-risk group (HR) comprising patients in risk classes III, IV and V: 63 patients; the primary endpoint of the study (MACE) was the occurrence of shock, the need for mechanical ventilation, and the occurrence of in-hospital death.
Results: total in-hospital mortality was 15.1%, significantly higher in the HR group (25.4% versus 7.2%, p=0.001). In logistic regression analysis, being in the HR group (OR=5.1; 95% CI: [1,637 - 16,093]; p=0.005)) and having renal impairment (OR=4.5; 95% CI: [1.457 - 14.075]; p=0.009) were the independent factors for the occurrence of MACE. After a mean follow-up of 18 ± 8 months, there were more deaths in the HR group (68.4% versus 33%, p=0.004).
Conclusion: the results of our study show that the PESI score is correlated with the severity of PE. This should encourage the widespread use of this risk score.

Background: The British Thoracic Society recommend that pulmonary embolism (PE) patients with low-risk Pulmonary Embolism Severity Index (PESI) scores are considered for outpatient (OP) management, in settings where robust pathways for follow-up and monitoring exist.
Methods: Retrospective cohort study. We reviewed the electronic records of 109 consecutive PE patients considered appropriate for OP management.

Suppression of Tumorigenicity 2 (ST2), a member of the interleukin-1 (IL-1) superfamily, is recognized as an important biomarker in inflammatory responses and cardiovascular diseases. Elevated serum levels of sST2 have prognostic value, particularly in cases of cardiac stress such as heart failure and acute pulmonary embolism (APE). We aimed to assess ST2 levels as a potential biomarker for right heart dysfunction in APE patients, particularly in the context of its limited predictive value for mortality and risk stratification.

Background: Accurate prediction of short-term mortality in patients with acute pulmonary embolism (PE) is critical for optimizing treatment strategies and improving patient outcomes. The Pulmonary Embolism Severity Index (PESI) is the current reference score used for this purpose, but it has limitations regarding predictive accuracy. Our aim was to develop a new short-term mortality prediction model for PE patients based on deep learning (DL) with multimodal data, including imaging and clinical/demographic data.

Increasing temperatures pose new challenges for track workers (TWs), who endure prolonged exposure to extreme heat and humidity. New methods are critically needed to assess their performance and heat tolerance, aiming to mitigate workplace accidents and long-term health consequences. This study aimed to investigate the physiological effects of heat exposure on TWs, using wearable sensors to monitor key physiological parameters under controlled environmental conditions.

Diagnosing acute pulmonary embolism (PE) is challenging due to its wide range of symptoms and numerous differential diagnoses. Medical professionals must balance performing all essential examinations and avoiding unnecessary testing. This study aimed to retrospectively audit the diagnosis and treatment of acute PE at a Swiss public teaching hospital to determine the adherence to current guidelines and to identify the factors associated with the delayed initiation of anticoagulation in PE patients.
