Large tumor thrombus extending into the right atrium through the inferior vena cava due to hepatocellular carcinoma: A case report.

This is a case report of a 54-year-old patient with hepatocellular cancer under palliative chemotherapy who admitted with dyspnea on minimal exertion and peripheral oedema over the past 5 days. Echocardiogram revealed a large echogenic mass in the right atrial cavity which did not enhance with intravenous echo contrast agent, and a distended inferior vena cava (IVC) which was occluded by echogenic material with no signs of flow. To distinguish with accuracy if the thrombus was a bland or tumor thrombus, contrast-enhanced Computed Tomography (CT) was performed.

Effect of FluoRoquinolones on Aortic Growth, aortic stIffness and wave refLEctionS (FRAGILES study).

: The widespread use of fluoroquinolones has been associated with the formation, dissection, and rupture of aortic aneurysms. Arterial biomarkers are established predictors of cardiovascular events. The present study was designed to investigate the effect of quinolones on arterial stiffness and aortic size for the first time.

Vaccine challenges in CLL: a comprehensive exploration of efficacy of SARS-CoV-2 immunization for patients with chronic lymphocytic leukemia.

Chronic lymphocytic leukemia (CLL) is characterized by disease- and treatment-related immunosuppression. Patients with CLL comprise a vulnerable population to coronavirus disease 2019 (COVID-19), while the protective effect of COVID-19 vaccination remains uncertain.We conducted a systematic review to evaluate published data reporting response to COVID-19 vaccination in patients with CLL.

Venetoclax Combination Treatment of Acute Myeloid Leukemia in Adolescents and Young Adult Patients.

Over the past two decades, the prognosis in adolescents and young adults (AYAs) diagnosed with acute myeloid leukemia (AML) has significantly improved. The standard intensive cytotoxic treatment approach for AYAs with AML, consisting of induction chemotherapy with anthracycline/cytarabine combination followed by consolidation chemotherapy or stem cell transplantation, has lately been shifting toward novel targeted therapies, mostly in the fields of clinical trials. One of the most recent advances in treating AML is the combination of the B-cell lymphoma 2 (Bcl-2) inhibitor venetoclax with hypomethylating agents, which has been studied in elderly populations and was approved by the Food and Drug Administration (FDA) for patients over 75 years of age or patients excluded from intensive chemotherapy induction schemas due to comorbidities.

Multimodality imaging approach in a case of vascular toxicity caused by cabozantinib.

Vascular toxicity caused by cancer treatment can present as vasospasm, arterial thrombosis, and accelerated atherosclerosis. We report a case of a 60-year-old man with metastatic renal cell carcinoma under cabozantinib treatment for 3 years who presented to the hospital with relapsing episodes of rest angina. Due to the presence of ST depression in the 12-lead electrocardiogram and elevated troponin, a non-ST-segment elevation myocardial infarction was suspected.

New-onset aplastic anemia after SARS-CoV-2 vaccination.

Aplastic anemia (AA) is a rare autoimmune disease. Drugs, viruses, and radiation are among the most common etiologic factors, and most cases have immune pathophysiology. SARS-CoV-2 vaccines have been linked with rare side effects, including cases of acquired aplastic anemia.

A Panorama of Immune Fighters Armored with CARs in Acute Myeloid Leukemia.

Acute myeloid leukemia (AML) is a devastating disease. Intensive chemotherapy is the mainstay of treatment but results in debilitating toxicities. Moreover, many treated patients will eventually require hematopoietic stem cell transplantation (HSCT) for disease control, which is the only potentially curative but challenging option.

Telomere biology: from disorders to hematological diseases.

Variations in the length of telomeres and pathogenic variants involved in telomere length maintenance have been correlated with several human diseases. Recent breakthroughs in telomere biology knowledge have contributed to the identification of illnesses named "telomeropathies" and revealed an association between telomere length and disease outcome. This review emphasizes the biology and physiology aspects of telomeres and describes prototype diseases in which telomeres are implicated in their pathophysiology.

Evidence that platelets from transfusion-dependent β-thalassemia patients induce T cell activation.

A hypercoagulable state leading to increased risk for thrombotic events represents one of the most common complications observed in transfusion-dependent β-thalassemia (TDT) patients. TDT patients have increased frequencies of circulating activated platelets. However, there is no information so far if platelets from TDT patients can activate T cells.

Effects of Chemotherapy on Aortic 18-Fluorodeoxyglucose Uptake in Patients With Hodgkin and Non-Hodgkin Lymphoma.

Background: Despite advances in the treatment of oncology patients, therapy-related side effects may lead to premature morbidity. Inflammatory activation that has been linked to cardiovascular disease is crucial for the pathogenesis of both Hodgkin (HL) and non-Hodgkin lymphoma (NHL).

Objectives: The purpose of this study was to assess the vascular effects of chemotherapy in patients with HL and NHL by positron emission tomography/computed tomography with 18-fluorodeoxyglucose (18-FDG PET/CT) and to investigate interactions with systemic inflammation as assessed by circulating inflammatory markers.

Acute Lymphoblastic Leukemia and Invasive Mold Infections: A Challenging Field.

Acute lymphoblastic leukemia (ALL) patients comprise a highly immunocompromised group due to factors associated either with the treatment or the disease itself. Invasive mold infections (IMIs) are considered to be responsible for higher morbidity and mortality rates in patients with hematologic malignancies, including ALL. Defining the exact incidence of IMIs in ALL patients has been rather complicated.

Real world data on the prognostic significance of monocytopenia in myelodysplastic syndrome.

Monocytopenia is a common finding in patients with myelodysplastic syndrome (MDS), but although monocytes may exhibit prognostic significance in MDS due to their role in innate immunity, they have not been incorporated in any prognostic scoring system for MDS. In this study, we analyzed national registry data from 1719 adults with MDS. Monocytopenia was present in 29.

Time-related aortic inflammatory response, as assessed with F-FDG PET/CT, in patients hospitalized with severely or critical COVID-19: the COVAIR study.

Aim: Arterial involvement has been implicated in the coronavirus disease of 2019 (COVID-19). Fluorine 18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) imaging is a valuable tool for the assessment of aortic inflammation and is a predictor of outcome. We sought to prospectively assess the presence of aortic inflammation and its time-dependent trend in patients with COVID-19.

Immune response and adverse events after vaccination against SARS-CoV-2 in adult patients with transfusion-dependent thalassaemia.

Patients with transfusion-dependent thalassaemia (TDT) are considered an at increased-risk population for severe and/or morbid coronavirus disease 2019 (COVID-19) infection. Timely vaccination is the main preventive method for severe COVID-19. Different adverse events and reactions after vaccination have been reported, with severe ones being extremely rare.

The effect of an mRNA vaccine against COVID-19 on endothelial function and arterial stiffness.

To fight the COVID-19 pandemic, messenger RNA (mRNA) vaccines were the first to be adopted by vaccination programs worldwide. We sought to investigate the short-term effect of mRNA vaccine administration on endothelial function and arterial stiffness. Thirty-two participants (mean age 37 ± 8 years, 20 men) who received the BNT162b2 mRNA COVID-19 vaccine were studied in three sessions in a sequence-randomized, sham-controlled, assessor-blinded, crossover design.

Engineering CAR-NK cells to secrete IL-15 sustains their anti-AML functionality but is associated with systemic toxicities.

Background: The prognosis of patients with recurrent/refractory acute myelogenous leukemia (AML) remains poor and cell-based immunotherapies hold promise to improve outcomes. Natural Killer (NK) cells can elicit an antileukemic response via a repertoire of activating receptors that bind AML surface ligands. NK-cell adoptive transfer is safe but thus far has shown limited anti-AML efficacy.
