The non-coding RNome after splenectomy.

Splenectomy is a common surgical procedure performed in millions of people worldwide. Epidemiologic data show that splenectomy is followed by infectious (sepsis) and non-infectious complications, with unknown mechanisms. In order to explore the role of the non-coding transcripts involved in these complications, we analysed a panel of circulating microRNAs (miRNAs), which were previously reported to be deregulated in sepsis, in the plasma of splenectomized patients.

Stress-Induced Cardiomyopathy in Cancer Patients.

Takotsubo syndrome, also known as stress-induced cardiomyopathy (SC), is underrecognized in cancer patients. This study aims to investigate the incidence, natural history, and triggers of SC in cancer patients and its impact on cancer therapy and overall survival. A total of 30 subjects fulfilled the diagnostic criteria for SC at MD Anderson Cancer Center over a 6-year period.

Association between ibrutinib and mid-cavitary Takotsubo cardiomyopathy: a case report and a review of chemotherapy-induced Takostubo's cardiomyopathy.

Takotsubo cardiomyopathy (TC) is a rare but increasingly recognized phenomenon, which can occur as a side effect of cancer treatment. We report an interesting case of a 53-year-old woman with non-small-cell lung cancer, who developed TC after chemotherapy with ibrutinib. Echocardiography revealed marked left ventricular dysfunction with apical hyperkinesis and mid-ventricular hypokinesia.

Management of CAD in Patients with Active Cancer: the Interventional Cardiologists' Perspective.

Purpose Of Review: Coronary artery disease in patients with active cancer presents particular challenges for clinicians, as optimum management is required in order to treat the underlying malignancy and to reduce morbidity and mortality associated with cardiovascular diseases. Special considerations must be made in respect to either primary or secondary thrombocytopenia, the presence of coagulopathies and the propensity of bleeding, vascular access complications, and increased risk of stent thrombosis.

Recent Findings: In presence of acute coronary symptoms, the cardio-oncology team has to make a complex decision between conservative medical management or early angiography (within 24 h) and revascularization.

Plasma Viral miRNAs Indicate a High Prevalence of Occult Viral Infections.

Prevalence of Kaposi sarcoma-associated herpesvirus (KSHV/HHV-8) varies greatly in different populations. We hypothesized that the actual prevalence of KSHV/HHV8 infection in humans is underestimated by the currently available serological tests. We analyzed four independent patient cohorts with post-surgical or post-chemotherapy sepsis, chronic lymphocytic leukemia and post-surgical patients with abdominal surgical interventions.

Ischemic Heart Disease: Special Considerations in Cardio-Oncology.

The interplay and balance between the competing morbidity and mortality of cardiovascular diseases and cancer have a significant impact on both short- and long-term health outcomes of patients who survived cancer or are being treated for cancer. Ischemic heart disease in patients with cancer or caused by cancer therapy is a clinical problem of emerging importance. Prompt recognition and optimum management of ischemic heart disease mean that patients with cancer can successfully receive therapies to treat their malignancy and reduce morbidity and mortality due to cardiovascular disease.

Cancer as a Risk Factor for Cardiovascular Disease.

Improvements in early diagnosis and cancer treatments have contributed to high survival rates for many cancer patients. However, these patients often die of cardiovascular disease rather than recurrence of their cancer. Heart disease manifesting after cancer may be due to several mechanisms: shared cardiovascular risks between cancer and cardiovascular disease, inflammatory states associated with malignancies, and/or cardiotoxic effects of cancer therapy.

Cellular and viral microRNAs in sepsis: mechanisms of action and clinical applications.

Regardless of its etiology, once septic shock is established, survival rates drop by 7.6% for every hour antibiotic therapy is delayed. The early identification of the cause of infection and prognostic stratification of patients with sepsis are therefore important clinical priorities.

microRNA and Chronic Lymphocytic Leukemia.

Expression profiling of microRNAs identified important differences in microRNA expression between CLL samples and normal CD5+ B-cells. Researchers have first discussed the dual role of miRNAs working as tumor suppressors (inhibiting malignant potential) or as oncogenes (activating malignant potential) in CLL pathogenesis. Understanding the roles of miRNAs in leukemic cells brings information on a new layer of gene regulation and also provides new markers for improved diagnosis and prognosis, as well as novel therapeutic options for CLL patients.

Key principles of miRNA involvement in human diseases.

Although rapid progress in our understanding of the functions of miRNA has been made by experimentation and computational approach, a considerable effort still has to be done in determining the general principles that govern the miRNA's mode of action in human diseases. We will further discuss how these principles are being progressively approached by molecular studies, as well as the importance of miRNA in regulating different target genes and functions in specific biological contexts. There is a great demand to understand the principles of context - specific miRNA target recognition in order to design future experiments and models of normal developmental and disease states.

Robotic splenectomy: what is the real benefit?

Background: The laparoscopic approach to a difficult splenectomy requires a longer total operative time and is frequently associated with an increased risk of bleeding and a high conversion rate.

Methods: A total of 418 elective splenectomies were registered in the Department of General Surgery and Liver Transplantation of Fundeni Clinical Institute between January 1995 and June 2012, of which 299 splenectomies (212 laparoscopic and 77 robotic) were performed by a single surgical team and retrospectively documented. The effect of the learning curve and the relative complexity of each type of procedure were analyzed using the Minimally Invasive Splenectomy Score, which further allowed categorizing the splenectomies as simple or difficult.

MicroRNAs and ceRNAs: therapeutic implications of RNA networks.

Introduction: A new concept of gene regulation, in which competitive endogenous RNAs (ceRNAs) compete for common microRNAs (miRNAs), suggests that mRNA targets have an active role as key elements in the regulation of miRNA availability within cells. ceRNAs are considered to be natural decoys of miRNA activity and can influence the expression of multiple miRNAs.

Areas Covered: A new complex network of indirect interaction among the RNA transcripts competing for the same pool of miRNAs has been described; in this network, the nodes are the targets, and the links between the nodes are the miRNAs the targets have in common, which form smaller subnetworks.

Morphometrical differences between resectable and non-resectable pancreatic cancer: a fractal analysis.

Background/aims: Pancreatic cancer is a highly aggressive cancer with a rising incidence and poor prognosis despite active surgical treatment. Candidates for surgical resection should be carefully selected. In order to avoid unnecessary laparotomy it is useful to identify reliable factors that may predict resectability.
