OBJECTIVE: Previous evidence suggested that intravascular ultrasound (IVUS) guidance could improve outcomes after drug-eluting stents (DES) placement, largely driven by data from observational studies. We, therefore, performed a meta-analysis and trial sequential analysis of randomized controlled trials to overcome this limitation. RESULTS: The retrieval process yielded 7 RCTs with 3,192 patients. Compared to the angiography guidance, IVUS-guided DES implantation was associated with a significant reduction in the major adverse cardiac events (MACE) (OR 0...

The pathological presence of tissue factor (TF) in cancer cells promotes tumor-initiated thrombosis and cancer metastasis. We found that TF is aberrantly present in large percentage of aggressive triple negative breast cancer (TNBC) and pancreatic adenocarcinoma (PaC), two most lethal forms of malignancy that urgently need effective treatment. TF expression in TNBC clustered with higher levels of vimentin, basal-type keratins KRT5/14 and caveolin-1 but lower levels of luminal-type biomarkers. We developed a novel and specific anti-TF therapeutic antibody SC1, which displayed an exceedingly high potency against TF extracellular domain (EC50: 0...

PURPOSE: Clinical indications are expanding for the use of fasciocutaneous free flaps in lower extremity traumatic reconstruction. We assessed the impact of muscle versus fasciocutaneous free flap coverage on reconstructive and functional outcomes. METHODS: A multicenter retrospective review was conducted on all lower extremity traumatic free flaps performed at Duke University (1997-2013) and the University of Pennsylvania (2002-2013). Muscle and fasciocutaneous flaps were compared in two subgroups (acute trauma and chronic traumatic sequelae), according to limb salvage, return to ambulation, flap outcomes, and secondary flap procedures...

The patient population with the need for oral anticoagulation to reduce stroke risk associated with atrial fibrillation (AF) and dual antiplatelet therapy to prevent stent thrombosis and myocardial infarction after percutaneous coronary intervention is increasing. However, patients treated with a triple therapy consisting of oral anticoagulation, aspirin, and a P2Y12 inhibitor have been demonstrated to be at high bleeding risk. The best combination of these agents and the duration of the different therapies are still uncertain...

Recently, time-of-flight (TOF) and gadolinium-enhanced MR angiography (MRA) imaging have been used to demonstrate subacute intramural hematoma in cervical artery dissection and to detect intraplaque haemorrhage. Our aim was to perform an exploratory study to analyse if venous thrombus-related signal changes (potentially showing iso- or hyperintensity) in cerebral venous sinus thrombosis (CVST) could be observed on 3D-TOF MRA imaging. We analysed retrospectively MRIs of CVST patients in whom both contrast-enhanced MR venography (CEMRV) and 3D-TOF sequences were performed in the acute/subacute phase (i...

BACKGROUND: Deep vein thrombosis (DVT) is a common complication of peripherally inserted central catheters (PICCs). PICCs are increasingly utilised in the management of cancer patients, a group which carries both additional risks for vascular thromboembolism as well as for complex morbidity. We analysed a cohort of cancer patients subjected to PICC insertion in a single cancer centre for the incidence of all-type vascular thromboembolism (VTE) and investigated relative risk factors. METHODS: In this clinical audit, the records of patients referred for PICC insertion in our centre in the period between 1/1/2011 and 1/4/2014 were retrospectively reviewed...

In the majority of patients with raised intracranial pressure, the papilledema is bilateral. Unilateral papilledema is rare in conditions causing intracranial hypertension, and it has been described in Foster-Kennedy syndrome and in some cases of idiopathic intracranial hypertension. It has never been reported in cerebral venous thrombosis. We report a young lady presenting with features of subacute onset of headache with seizures, on evaluation she had superior sagittal and bilateral lateral sinus thrombosis...

The diagnosis of deep vein thrombosis (DVT) and pulmonary embolism (PE) during pregnancy still relies on objective imaging. Ancillary testing such as clinical prediction rules and D-dimer testing may have a role in excluding both DVT and PE in these pregnant patients even as we await results from prospective management studies. The anatomical distribution of DVT in pregnancy differs from those in non-pregnant patient with a greater propensity for proximal iliac vein thrombosis. Using leg ultrasonography with compression maneuvers from the femoral vein to popliteal vein and doppler assessment of the iliac vein in a single examination, appears adequate in most pregnant women with suspected DVT, in excluding DVT...

On the effort to screen antibiotics against Methicillin resistant Staphylococcus aureus (MRSA), an actinomycete strain which can produce bactericidal compound was isolated from a marine sponge of Kanyakumari Coast, India. Two anti-MRSA compounds (PVI401 and PVI402) were isolated from the fermentation plates of Streptomyces pharmamarensis ICN40. TLC bioautography analysis yielded two active spots with Rf value of 0.75 (PVI401) and 0.8 (PVI402) from the crude extract. Both the compounds were characterized by HR-LC-MS analysis...
