Mitochondrial DNA sequencing demonstrates clonality of peritoneal implants of borderline ovarian tumors.

Borderline ovarian tumors are rare low malignant potential neoplasms characterized by the absence of stromal invasion, whose main prognostic factors are stage and type of peritoneal implants. The latter are defined as invasive when cell proliferation invades the underlying tissue (peritoneal surface, omentum and intestinal wall), or noninvasive. It is still unknown if these implants are metastatic spread from the primary ovarian mass or a neoplastic transformation de novo of the peritoneal surface.

Molecular and metabolic features of oncocytomas: Seeking the blueprints of indolent cancers.

Oncocytic tumors are a peculiar subset of human neoplasms in which mitochondria have been proven to have a prominent role. A number of paradoxes render these clinical entities interesting from the translational research point of view. Most oncocytic tumors are generally metabolically constrained due to the impaired respiratory capacity and lack of the ability to respond to hypoxia, yet they maintain features that allow them to strive and persist in an indolent form.

Intracranial hemorrhage recurrence on vitamin K antagonist: severity of the first episode and HASBLED score fail to identify high-risk patients from the CHIRONE study.

The most feared complication of vitamin K antagonists (VKAs) treatment is intracranial hemorrhage (ICH). The previously published CHIRONE Study fails to identify risk factors associated with ICH recurrence after VKAs resumption. The aim of this secondary analysis of the study is to evaluate if patients who need surgery or with severe neurological sequelae after the first episode show a higher risk of ICH recurrence.

Bronchial artery embolization for the treatment of haemoptysis in pulmonary hypertension.

Purpose: To test the efficacy of bronchial artery embolization (BAE) to treat haemoptysis in pulmonary hypertension (PH).

Methods: 33 patients were treated by BAE for haemoptysis associated with PH (PH group = 21) or non-associated with PH (control group = 12). The details of procedure, outcome, and rate of relapse were compared between the two groups.

Assessment of the neutron dose field around a biomedical cyclotron: FLUKA simulation and experimental measurements.

In the planning of a new cyclotron facility, an accurate knowledge of the radiation field around the accelerator is fundamental for the design of shielding, the protection of workers, the general public and the environment. Monte Carlo simulations can be very useful in this process, and their use is constantly increasing. However, few data have been published so far as regards the proper validation of Monte Carlo simulation against experimental measurements, particularly in the energy range of biomedical cyclotrons.

Multicentric survey on dose reduction/interruption of cancer drug therapy in 12.472 patients: indicators of suspected adverse reactions.

Antiblastic drugs have a high number of potential side-effects. Paradoxically, according to the National Network of Pharmacovigilance, the number of reported adverse reactions to these agents is proportionally lower than that registered for non antiblastic drugs. Critical phenomena such as treatment interruptions and significant dose reductions within the first two months of use may be indicators of adverse drug reactions.

Gender differences in outcomes following isolated coronary artery bypass grafting: long-term results.

Background: The main purpose of this study was to evaluate the impact of gender on outcomes after isolated coronary artery bypass grafting, in terms of 5-year rates of overall death, cardiac-related death, myocardial infarction, re-hospitalization, repeat percutaneous or surgical revascularization, stroke, new pacemaker implantation, postoperative renal failure, heart failure and need for long-term care.

Results: In the matched cohort, males received significantly more bypass grafts (3.

An update on the pharmaceutical management of thrombosis.

Anticoagulants such as heparins and vitamin K antagonists (VKA) are effective for thrombosis prevention and treatment, but are associated with the risk of bleeding and other limitations, spurring the search for improved drugs. Areas covered: to evaluate the newer anticoagulants, focusing on those tested in phase III clinical trials such as direct oral anticoagulants (DOACs), antisense oligonucleotides (ASO) and warfarin analogues. DOACs such as dabigatran, rivaroxaban, apixaban and edoxaban are licensed for stroke prevention in atrial fibrillation and treatment of venous thromboembolism, dabigatran, rivaroxaban and apixaban for postoperative thromboprophylaxis in patients undergoing elective hip or knee arthroplasty and rivaroxaban for secondary prevention of acute coronary syndromes.

Ultrasound Characteristics of Calf Deep Vein Thrombosis and Residual Vein Obstruction After Low Molecular Weight Heparin Treatment.

Objective/background: Calf deep vein thrombosis (CDVT) is frequently found in symptomatic outpatients, but CDVT ultrasound diagnostic criteria are still debated. It has been proposed that only clots with ≥5 mm maximum diameter can be considered as CDVT.

Aims: To assess clot diameters and characteristics of CDVT, and to assess the recanalization rate of CDVT after anticoagulant treatment.

Diagnostic Accuracy of a New d-Dimer Assay (Sclavo Auto d-Dimer) for Exclusion of Deep Vein Thrombosis in Symptomatic Outpatients.

In patients presenting non-high clinical pretest probability (PTP), a negative d-dimer can exclude venous thromboembolism without imaging tests. However, each d-dimer assay should be validated in prospective studies. We evaluated an automated d-dimer immunoassay using the Sclavo Auto d-dimer (Sclavo Diagnostics Int, Sovicille, Italy) provided by Dasit Diagnostica (Cornaredo, Milan, Italy).

Materials And Methods: Subjects were enrolled in the three large prospective multicentre studies: PROLONG (NEJM 2006) PROLONG II (Blood 2010) and DULCIS (Blood 2014).

Gastroduodenal Disorders.

Symptoms that can be attributed to the gastroduodenal region represent one of the main subgroups among functional gastrointestinal disorders. A slightly modified classification into the following 4 categories is proposed: (1) functional dyspepsia, characterized by 1 or more of the following: postprandial fullness, early satiation, epigastric pain, and epigastric burning, which are unexplained after a routine clinical evaluation; and includes 2 subcategories: postprandial distress syndrome that is characterized by meal-induced dyspeptic symptoms and epigastric pain syndrome that does not occur exclusively postprandially; the 2 subgroups can overlap; (2) belching disorders, defined as audible escapes of air from the esophagus or the stomach, are classified into 2 subcategories, depending on the origin of the refluxed gas as detected by intraluminal impedance measurement belching: gastric and supragastric belch; (3) nausea and vomiting disorders, which include 3 subcategories: chronic nausea and vomiting syndrome; cyclic vomiting syndrome; and cannabinoid hyperemesis syndrome; and (4) rumination syndrome.

In this study, the frequency and the reporting rate of cardiovascular findings in chest CT examinations were retrospectively assessed.

Materials And Methods: This study was approved by the institutional review board of each participating center.

Prognostic Evaluation of Disease Outcome in Solid Tumors Investigated With 64Cu-ATSM PET/CT.

Purpose: Cu-ATSM is a very promising PET radiopharmaceutical for tumor imaging of hypoxia. One of the advantages of this compound compared with other hypoxia-avid tracers is the high tumor-to-background signal offered, which guaranties facilitated tumor delineation. This study analyzes optimal semiquantitative and quantitative parameters obtained by Cu-ATSM PET/CT in the same cohort of patients with special focus on their correlation to disease outcome.

Experimental measurement and Monte Carlo assessment of Argon-41 production in a PET cyclotron facility.

In a medical cyclotron facility, (41)Ar (t1/2 = 109.34 m) is produced by the activation of air due to the neutron flux during irradiation, according to the (40)Ar(n,γ)(41)Ar reaction; this is particularly relevant in widely diffused high beam current cyclotrons for the production of PET radionuclides. While theoretical estimations of the (41)Ar production have been published, no data are available on direct experimental measurements for a biomedical cyclotron.

An 82-year-old female with an untreated right femoral neck fracture, and a severe aortic valve stenosis was admitted to a cardiac surgery department for surgical treatment of the valve disease.

Cardiac resynchronization therapy and cardiac sympathetic function.

Background: Cardiac resynchronization therapy (CRT) is an established therapy for advanced congestive heart failure, improving both survival and hospitalization. The mechanism beneath these improvements still needs to be defined as about one-third of the patients do not benefit from resynchronization. Restoration of sympatho-vagal function can play a significant role in the process, but available data are limited.

High-throughput genotyping of high-risk Human Papillomavirus by MALDI-TOF Mass Spectrometry-based method.

A high-throughput matrix-assisted laser desorption ionisation-time of flight (MALDI-TOF) mass spectrometry (MS)-based method was here developed to genotype 16 high-risk human papillomavirus (HPV) types in cervical cytology specimens. This method was compared to a commercial kit, the Inno-LiPA HPV genotyping assay, which detects a broad spectrum of HPV types. HPV DNA was assessed by the two methods in a total of 325 cervical cytology specimens collected in PreservCyt® solution.
