Summary: This study investigates the use of capnography, a method that monitors CO2 concentration in respiratory gases, for the differential diagnosis of PE. The results suggest that the capnographic curve can be used to predict the occurrence of PE based on the etCO2 values. The study findings provide potential clinical significance for the use of capnography in everyday practice.

Summary: The incidence of acute pulmonary embolism (APE) has been increasing annually, and the diagnosis of APE is a challenge for clinicians. This study evaluated multiple diagnostic indicators and found that lung imaging had the highest diagnostic value, followed by D-dimer, Geneva rules, and Wells rules. Clinical trials are recommended to establish an early decision-making model for the diagnosis of pulmonary embolism.

Summary: Nontrombotic pulmonary embolism refers to the embolization of different types of materials into pulmonary circulation. Its clinical presentation and laboratory findings are nonspecific, leading to misdiagnosis as pulmonary thromboembolism. Understanding the risk factors and specific symptoms is crucial for rapid and correct diagnosis.

Summary: This study evaluated the feasibility and accuracy of using CT pulmonary angiography (CTPA) for diagnosing acute heart failure (HF) in emergency department patients. The results showed that both HUratio and HUdiff had a high sensitivity for diagnosing HF, indicating their potential as viable diagnostic markers.

Summary: This study suggests that a Doppler index, TRPG/AcT, improves the assessment of symptomatic pulmonary embolism (PE) survivors. TRPG/AcT > 0.6 indicates a high probability of chronic thromboembolic pulmonary hypertension (CTEPH) or chronic thromboembolic pulmonary disease (CTED), while TRPG/AcT < 0.6 allows for the safe exclusion of CTEPH + CTED in patients with a low echocardiographic probability of pulmonary hypertension (PH).

Summary: This study assessed the role of ventilation imaging in COVID-19 patients undergoing lung scintigraphy for suspected pulmonary embolism (PE). The findings showed that in this population, only 57% of patients could confidently exclude PE without ventilation imaging, while 31% of patients required ventilation imaging to rule out PE. The study also revealed a low prevalence of PE (12%).

Summary: Pulmonary embolism (PE) is a common cause of maternal morbidity and mortality during pregnancy, but diagnosing it in pregnant women is difficult. Two prospective studies have demonstrated the safety of using clinical probability assessment, D-dimer, venous compression ultrasonography, and CT angiography to exclude PE without chest imaging. Implementing these validated diagnostic strategies in clinical practice should be a high priority goal, as pregnant women are at a high risk of inappropriate diagnostic management.

Summary: This study evaluated the clinical care provided to cancer patients hospitalized for acute pulmonary embolism and assessed the association between type of cancer, in-hospital care, and clinical outcomes. The results showed that cancer patients were less likely to receive invasive management compared to non-cancer patients. Cancer patients had higher odds of mortality, with lung cancer patients having the highest mortality and hemorrhagic stroke risk, while colorectal cancer patients had the highest bleeding risk.

Summary: Heart transplantation is the standard therapy for end-stage heart failure, but patients with submassive pulmonary embolism and heart failure typically need to wait for extended periods of time before being eligible for transplant surgery. In some cases, successful simultaneous pulmonary thromboendarterectomy and heart transplantation have been reported.

Summary: Venous thromboembolism (VTE) is a common complication in cancer patients, but its clinical presentation and prognosis are not well understood. A retrospective study analyzed 259 patients treated for pulmonary embolism (PE) and found that PE was often incidentally diagnosed among cancer patients and had a lower severity compared to non-cancer patients. Despite lower PE severity, cancer patients had higher D-dimer levels at discharge and poorer prognosis during follow-up. Active malignancy was associated with major adverse cardiovascular events (MACE) and major bleeding. D-dimer at discharge was an independent predictor of mortality, even after adjusting for malignancy.

Summary: A study based on a multicenter registry found that there was no significant difference in the long-term risk of recurrent VTE among patients with different severities of PE at initial diagnosis beyond 3 months, although patients with massive PE were more likely to develop severe recurrent PE events.

Summary: The management of suspected pulmonary embolism in pregnant women in the emergency department raises numerous issues. The physiological changes during pregnancy increase the number of emergency visits for symptoms such as chest pain, dyspnea, and faintness, which may interfere with the assessment of pulmonary embolism probability. The elevated D-dimers and inconclusive chest imaging further complicate the diagnostic pathway. However, it is crucial not to miss a diagnosis of pulmonary embolism during pregnancy while minimizing unnecessary exposure to chest imaging for the patient and her fetus. Two validated strategies have been developed for decision making in pregnant women. The first strategy is based on the Geneva score, which includes performing a proximal compression ultrasound in patients with high probability or a D-dimer level greater than 500 ng/mL. The second strategy is based on the YEARS algorithm, with ultrasound performed only in patients with symptoms suggestive of associated lower limb venous thrombosis, followed by D-dimer testing with a threshold of 500 or 1,000 ng/mL based on clinical probability. The safety of both strategies has been demonstrated. The advantage of the first strategy lies in its reliance on objective data, while the second strategy benefits from using a decision threshold of 1,000 ng/mL in patients without any of the YEARS criteria.

Summary: This study aimed to evaluate the efficacy and safety of extended perioperative thromboprophylaxis with low molecular weight heparin in patients undergoing resection for colorectal cancer. The study found that extended duration thromboprophylaxis did not improve disease-free survival or overall survival in these patients compared to in-patient postoperative thromboprophylaxis alone. The incidences of venous thromboembolism and postoperative major bleeding were low and similar between groups.

Summary: This study aims to assess the differences in clinical benefits, harms, and costs of stopping versus continuing anticoagulant therapy indefinitely for a first unprovoked venous thromboembolism (VTE). A probabilistic Markov model will be developed to estimate life-years, quality-adjusted life-years, costs, and incremental cost-effectiveness ratios. The results will be disseminated through conferences and a peer-reviewed journal.

Summary: The study validates a new diagnostic strategy for suspected pulmonary embolism, aiming to reduce the use of CTPA. The PEGeD algorithm can exclude the possibility of PE based on low and moderate clinical pretest probabilities, combined with D-dimer levels. The study demonstrates the external validation of the PEGeD algorithm in an independent cohort.

Summary: This study evaluated the association between obesity and body mass index (BMI) with confirmed pulmonary embolism (PE) in patients with suspected PE and assessed the efficiency and safety of the age-adjusted D-dimer strategy in obese patients. The results showed that BMI and obesity were not associated with confirmed PE. The use of the age-adjusted D-dimer strategy increased the proportion of obese patients in whom PE was considered ruled out without imaging.

Summary: This study aimed to develop and evaluate an automated threshold method based on total lung function for the delineation of lung functional volumes using Gallium-68 MAA lung PET/CT imaging. The results showed that the WLF threshold method provided more reliable and consistent functional volumes, especially in patients with normal PFTs, as compared to the pmax method. This new approach, relatively unaffected by the presence of hot spots, is clinically meaningful for clinicians.

Summary: This study found that diabetes and high CRP level were risk factors for arterial and venous thromboses in COVID-19 pneumonia patients hospitalized in general wards. Obesity was not associated with a higher risk of thrombosis. Higher doses of anticoagulants could be considered in these high-risk patients, opening up opportunities for interventional studies.
