ABSTRACT

BACKGROUND: In patients clinically suspected of pulmonary embolism (PE), physicians often rely on an intuitive estimation ('gestalt') of PE presence. Although shown to be predictive, gestalt is criticized for its assumed variation across physicians and lack of standardization.

OBJECTIVES: To assess the diagnostic accuracy of gestalt in diagnosing PE and gain insight into its possible variation.

METHODS: We performed an individual patient data meta-analysis including patients suspected of PE. The primary outcome was the diagnostic accuracy of gestalt for diagnosing PE, quantified as a risk ratio (RR) between gestalt and PE from a two-stage random-effect log-binomial meta-analysis regression as well as gestalts' sensitivity and specificity. Variability of these measures was explored across different healthcare settings, publication period, PE prevalence, patient subgroups (sex, heart failure, chronic lung disease, and items of the Wells score other than gestalt), and age.

RESULTS: We analysed 20,770 patients suspected of PE from 16 original studies. The prevalence of PE in patients with and without a positive gestalt was 28.8% versus 9.1%, respectively. The overall RR was 3.02 (95%CI 2.35, 3.87) and overall sensitivity and specificity were 74% (95%CI 68-79%) and 61% (95%CI 53-68%). Although variation was observed across individual studies (I2-90.63%), diagnostic accuracy was consistent across all subgroups and healthcare settings.

CONCLUSIONS: A positive gestalt was associated with a threefold increased risk of PE in suspected patients. Although variation was observed across studies, the RR of gestalt was similar across prespecified subgroups and healthcare settings, exemplifying its diagnostic value for all patients suspected of PE.

Current status and hotspots evolution in myeloproliferative neoplasm: a bibliometric analysis from 2001 to 2022

Eur Rev Med Pharmacol Sci. 2023 May;27(10):4510-4519. doi: 10.26355/eurrev_202305_32457.

ABSTRACT

OBJECTIVE: In the last 20 years, the field of myeloproliferative neoplasm (MPN) has changed dramatically. This study aims to provide new ideas for the scientific research of MPN by systematically combing the literature.

MATERIALS AND METHODS: CiteSpace and VOSviewer were used to carry out a bibliometric analysis of MPN papers to visualize the development process, research hotspots, and cutting-edge trends in clinical practice, mechanisms, and management strategies related to MPN.

RESULTS: 1,099 authors from 736 institutions in 113 countries/regions published 11,922 papers in 1,807 academic journals. The United States and Italy were in the leading positions in this research field. Mayo Clinic is the institution with the largest number of publications. Only a few countries and institutions have shown active cooperation. Ayalew Tefferi and Ruben A. Mesa are outstanding contributors to the field. Blood and Leukemia are considered influential journals based on publications and citations. In this field, the research of MPN mainly focuses on the occurrence and progress mechanism of MPN, the clinical significance of non-driving gene mutation, optimization of primary and secondary thromboprophylaxis, clinical research of long-acting interferon and JAK2 inhibitors, and exploration of better therapies for myelofibrosis (primary and secondary) and post-MPN acute myeloid leukemia (AML).

CONCLUSIONS: The research is in a stage of rapid development. The collaboration between different institutions or countries (regions) still has room to grow. The hotspot analysis shows that the research of MPN mainly focuses on gene mutation, thrombosis, new drug applications, disease progression, etc.
