ABSTRACT

RATIONALE: Few isolated case reports and case series have reported arterial and venous thromboembolism related to adenomyosis; however, the underlying mechanism remains unclear.

PATIENT CONCERNS: A 47-year-old woman presented with dizziness, nausea, vomiting, and loss of consciousness after red blood cell transfusion. She was being treated for menorrhagia and severe anemia.

DIAGNOSES: Magnetic resonance imaging showed multiple infarctions in right cerebellum and bilateral frontal, parietal, and occipital lobes. Echocardiography performed during the evaluation for the source of emboli revealed multiple echogenic masses on the tricuspid aortic valve. There was no evidence of infection, and the masses on the aortic valve were diagnosed as nonbacterial thrombotic endocarditis. The levels of autoimmune antibodies and tumor markers except for carbohydrate antigen 19-9 and cancer antigen 125 were within the normal range. Uterine ultrasound showed a large adenomyosis. The patient was diagnosed with multiple cerebral and cerebellar infarctions due to nonbacterial thrombotic endocarditis, and hormone therapy and anticoagulation with warfarin were initiated.

INTERVENTIONS: The patient did not develop recurrent infarction during anticoagulant therapy; however, menorrhagia worsened requiring total hysterectomy.

OUTCOMES: The patient did not experience recurrent infarction despite the absence of anticoagulant therapy during the 3-year follow-up period.

LESSONS: The present case adds to the limited number of previously reported cases and supports that, albeit rare, adenomyosis can be associated with embolic infarction and suggests that nonbacterial thrombotic endocarditis might be the link between adenomyosis and embolic infarction.

Body Mass Index (BMI) Related Morbidity with Thyroid Surgery

Laryngoscope. 2023 Jun 2. doi: 10.1002/lary.30789. Online ahead of print.

ABSTRACT

OBJECTIVES: The increase in incidence of thyroid cancer correlates with strict increases in body mass index (BMI) and obesity in the United States. Thyroid hormone dysregulation has been shown to precipitate circulatory volume, peripheral resistance, cardiac rhythm, and even cardiac muscle health. Theoretically, thyroid surgery could precipitate injury to the cardiopulmonary system.

METHODS: The American College of Surgery National Quality Improvement Program database was queried for thyroidectomy cases in the 2007-2020 Participant User files. Continuous and categorical associations between BMI and cardiopulmonary complications were investigated as reported in the database.

RESULTS: The query resulted 186,095 cases of thyroidectomy procedures in which the mean age was 51.3 years and sample was 79.3% female. No correlation was evident in univariate and multivariate analyses between BMI and the incidence of postoperative stroke or myocardial infarction. The incidence of complications was extremely low. However, risk of deep venous thrombosis correlated with BMI in the categorical, univariate, and multivariate (OR 1.036, CI 1.014-1.057, p < 0.01) regression analysis. Additionally, increased BMI was associated with increased risk of pulmonary embolism (PE) (OR 1.050 (1.030, 1.069), p < 0.01), re-intubation (OR 1.012 (1.002, 1.023), p = 0.02), and prolonged intubation (OR 1.031 (1.017, 1.045), p < 0.01).

CONCLUSION: Despite the rarity of cardiopulmonary complications during thyroid surgery, patients with very high BMI carry a significant risk of deep venous thrombosis, PE, and prolonged intubation.

Prevention of venous thromboembolism in patients with cancer

BMJ. 2023 Jun 1;381:e072715. doi: 10.1136/bmj-2022-072715.

ABSTRACT

Venous thromboembolism (VTE) is a major cause of both morbidity and mortality in patients with cancer. Venous thromboembolism, which includes both deep vein thrombosis and pulmonary embolism, affects a sizable portion of patients with malignancy and can have potentially life threatening complications. Accurate assessment of risk as well as diagnosis and treatment of this process is paramount to preventing death in this high risk population. Various risk models predictive of venous thromboembolism in patients with cancer have been developed, and knowledge of these rubrics is essential for the treating oncologist. Subgroups of particular interest are inpatients receiving chemotherapy, postoperative patients after surgical debulking, and patients undergoing radiotherapy. Numerous newer drugs have become available for the prevention of venous thromboembolism in patients with cancer who are at high risk of developing the disease. These include the class of drugs called direct oral anticoagulants, (DOACs) which do not require the same monitoring that other modalities have previously required and are taken by mouth, preventing the discomfort associated with subcutaneous strategies. The appropriate risk stratification and intervention to prevent venous thromboembolism are vital to the treatment of patients with cancer.

Accuracy of the Physicians' Intuitive Risk Estimation in the Diagnostic Management of Pulmonary Embolism: An Individual Patient Data Meta-Analysis

J Thromb Haemost. 2023 May 30:S1538-7836(23)00438-5. doi: 10.1016/j.jtha.2023.05.023. Online ahead of print.

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.

Thrombotic Complications in Children with COVID-19 and MIS-C

J Thromb Haemost. 2023 May 31:S1538-7836(23)00434-8. doi: 10.1016/j.jtha.2023.05.020. Online ahead of print.

ABSTRACT

Coronavirus disease 2019 (COVID-19) associated coagulopathy is multifactorial and involves inflammation driven hypercoagulability, endothelial dysfunction, platelet activation and impaired fibrinolysis. Hospitalized adults with COVID-19 are at an increased risk of both venous thrombo-embolism (VTE) and ischemic stroke, resulting in adverse outcomes including mortality. While children with COVID-19 follow a less severe course, both arterial and venous thrombosis have been reported in hospitalized children with COVID-19. Additionally, some children develop a post-infectious, hyper-inflammatory illness termed Multisystem Inflammatory Syndrome of Childhood (MIS-C), which is also associated with hypercoagulability and thrombosis. Several randomized trials have evaluated the safety and efficacy of antithrombotic therapy in adults with COVID-19, though similar pediatric data are lacking. In this narrative review we discuss the postulated pathophysiology of COVID-19 coagulopathy, and summarize principal findings of the recently completed adult trials of antithrombotic therapy. We provide an up-to-date summary of pediatric studies investigating the rate of VTE and ischemic stroke in COVID-19 and MIS-C, in addition to reviewing the findings of the single, non-randomized pediatric trial investigating the safety of prophylactic anticoagulation. Lastly, we outline the adult and pediatric consensus guidelines on the use of antithrombotic therapy in this cohort. A detailed discussion of the practical implementation and current limitations of published data will hopefully address knowledge deficits surrounding the use of antithrombotic therapy in children with COVID-19, and generate hypotheses for future research.

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.

Long COVID syndrome after SARS-CoV-2 survival in patients with pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension

Pulm Circ. 2023 May 31;13(2):e12244. doi: 10.1002/pul2.12244. eCollection 2023 Apr.

ABSTRACT

Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) patients have a more severe COVID-19 course than the general population. Many patients report different persistent symptoms after SARS-CoV-2 infection. The aim of our study is to analyze the prevalence of long COVID-19 symptoms and assess if COVID-19 affects pulmonary hypertension (PH) prognosis. PAH/CTEPH patients who survived COVID-19 for at least 3 months before visiting the PH centers were included in the study. The patients were assessed for symptoms in acute phase of SARS-CoV-2 infection and persisting in follow-up visit, WHO functional class, 6-min walk distance, NT-proBNP concentration. The COMPERA 2.0 model was used to calculate 1-year risk of death due to PH at baseline and at follow-up. Sixty-nine patients-54 (77.3%) with PAH and 15 (21.7%) with CTEPH, 68% women, with a median age of 47.5 years (IQR 37-68)-were enrolled in the study. About 17.1% of patients were hospitalized due to COVID-19 but none in an ICU. At follow-up (median: 155 days after onset of SARS-CoV-2 symptoms), 62% of patients reported at least 1 COVID-19-related symptom and 20% at least 5 symptoms. The most frequently reported symptoms were: fatigue (30%), joint pain (23%), muscle pain (17%), nasal congestion (17%), anosmia (13%), insomnia (13%), and dyspnea (12%). Seventy-two percent of PH patients had a low or intermediate-low risk of 1-year death due to PH at baseline, and 68% after COVID-19 at follow-up. Over 60% of PAH/CTEPH patients who survived COVID-19 suffered from long COVID-19 syndrome, but the calculated 1-year risk of death due to PH did not change significantly after surviving mild or moderate COVID-19.
