INTRODUCTION: Treatment of multidrug-resistant Gram-positive infections caused by Staphylococcus aureus remains as a clinical challenge due to emergence of new resistance mechanisms. Tedizolid is a next-generation oxazolidinone, recently approved for skin and soft tissues infections. We conducted a study to determine in vitro susceptibility to vancomycin, daptomycin, linezolid, and tedizolid in MRSA clinical isolates from adult patients with skin and soft tissue infections. MATERIAL AND METHODS: Methicillin-resistant S...

The purpose of this study is to measure the hemodynamics on the effect of Valsalva maneuver aiming at pulmonary thromboembolism (PTE) using 2-dimensional (2D) phase contrast imaging of magnetic resonance image (MRI), Philips Ingenia 3.0-tesla (T). The maximal inspiration reduced the blood flow rate in various degrees at all measurement positions, superior vena cava (SVC), inferior vena cava (IVC), pulmonary artery (PA), ascending aorta (AA), and descending aorta (DA). This result suggests that the contrast effect in the PA might become weak during general PA phase to give a substantial influence of Valsalva maneuver in the condition after maximum inspiration...

Nutcracker syndrome is a clinical entity leading to renal venous hypertension due to extrinsic compression of the left renal vein by the superior mesenteric artery. Current surgical therapy involves placement of an oversized renal vein stent with partial protrusion into the inferior vena cava (IVC) to relieve stenosis and prevent stent migration. Here, we present a patient with intractable pain and hematuria secondary to nutcracker syndrome who underwent left renal vein stent placement and developed recurrent symptoms due to flow-limiting kinking at the left renal hilum, with partial obstruction of the IVC from pseudointimal hyperplasia...

Here, we present a case report of a 60-year-old female with a 5-cm tumor in the inferior vena cava (IVC) that was positive for c-kit and CD34 expression. Thus, we considered this to be an extragastrointestinal c-kit-positive stromal tumor (EGIST). To the best of our knowledge, no primary EGISTs of the IVC have been described thus far. The potential occurrence of EGISTs outside the tubular gastrointestinal tract should be recognized in the differential diagnosis of tumors of the great vessels. Thus, we concluded that primary c-kit-positive stromal tumors of the IVC do indeed occur...

PURPOSE: The inferior vena cava (IVC) is one of the vital veins inside the human body. Accurate segmentation of the IVC from contrast-enhanced CT images is of great importance. This extraction not only helps the physician understand its quantitative features such as blood flow and volume, but also it is helpful during the hepatic preoperative planning. However, manual delineation of the IVC is time-consuming and poorly reproducible. METHODS: In this paper, we propose a novel method to segment the IVC with minimal user interaction...

We encountered a 45-year-old Japanese man who suffered from pulmonary thromboembolism and huge right ventricular thrombus after inferior vena cava (IVC) filter implantation without apparent thrombus in either the deep veins or inside the IVC filter. The biochemical data showed a discrepancy in the level of fibrinogen between the immunological and thrombin time methods, suggesting hypodysfibrinogenemia. The sequencing of the fibrinogen γ-chain gene (FGG) revealed a novel heterozygous missense mutation in exon 8 - a TGT to TCT transversion in codon 326 - resulting in an amino acid substitution of serine for cysteine (γCys326Ser)...

The mechanism of ultrasound thrombolysis (UT) is generally attributed to cavitation. The insufficiency of microbubbles (MB) to serve as cavitation nuclei in the vessel-obstructing thrombi significantly reduces the effectiveness of UT. Taking advantage of the widely performed catheter-directed therapy (CDT), in a thrombo-embolized rabbit IVC model with a simultaneous catheter directed rt-PA thrombolysis procedure, guided moderate mechanical index longer pulses from a modified diagnostic ultrasound transducer, combined with an intraclot infusion of MB, significantly accelerated the thrombolysis process...

The effects of epidermal growth factor (EGF) concentrations (0, 10, 50, and 100ng/ml) on in vitro culture (IVC) of equine preantral follicles were evaluated using histology, estradiol and reactive oxygen species (ROS) production and metabolomics. After IVC, the percentage of normal follicles was lower (P<0.05) for all treatments when compared to non-cultured control. EGF 50ng/ml treatment had more (P<0.05) normal follicles at Day 7 of culture when compared with EGF 0 and 100ng/ml. EGF 50ng/ml had more (P<0...

Although anticoagulation remains the mainstay of therapy for patients with venous thromboembolism, guidelines recommend the use of inferior vena cava (IVC) filters in those who fail anticoagulation or have contraindications to its use. Short-term use of filters has proven effective in reducing the rate of pulmonary embolism. However, their extended use is associated with a variety of complications such as thrombosis, filter migration, or caval perforation, thus making a case for timely filter retrieval. This is the case of a 68-year-old female with a history of chronic oral anticoagulation use for multiple deep venous thrombi (DVT) and pulmonary emboli (PE) who required cervical and thoracic spinal intervention for spondylosis and foramina stenosis...

Ample studies have shown that housing can affect the health, welfare and behavior of mice and therefore, the outcomes of certain experiments. The aim of this study was to investigate if three widely used housing systems, Open Top Cages (OTC), Motor Free Ventilated Cages (MFVC) and Individually Ventilated Cages (IVC) may affect exploratory and anxiety-related behaviors in mice. Subjects were 8week-old male C57Bl/6J mice (n=36) divided into three groups, OTC, IVC and MFVC groups, respectively. The experimental procedure consisted of two behavioral tests: the open field and the elevated plus maze test...

OBJECTIVE: Advanced renal cell carcinoma (RCC) has a significant predisposition to vascular invasion. Tumor vascular invasion and thrombus are found in the renal vein and the inferior vena cava (IVC) in up to 10% to 25% of patients. This study reviewed the current status of radical nephrectomy with IVC thrombectomy for advanced RCC. METHODS: A two-level search strategy of the literature (MEDLINE, PubMed, The Cochrane Library, and Google Scholar) for relevant articles listed between January 2000 and December 2015 was performed...

BACKGROUND: Major vascular involvement (IVC or portal vein) for intrahepatic cholangiocarcinoma (ICC) has traditionally been considered a contraindication to resection. We sought to define perioperative outcomes and survival of ICC patients undergoing hepatectomy with major vascular resection in a large international multi-institutional database. METHODS: A total of 1087 ICC patients who underwent curative-intent hepatectomy between 1990 and 2016 were identified from 13 institutions...

BACKGROUND: Classic caval reconstruction during liver transplantation involves complete cross-clamping and resection of the recipient inferior vena cava (IVC) followed by donor IVC interposition. Other techniques preserve the IVC, with piggyback (PB) to the hepatic veins or side-to-side (SS) caval anastomosis. Avoidance of cross-clamping may be beneficial for minimizing hemodynamic instability and transfusion requirements. METHODS: Retrospective review of a provincial transplant database (2007-2011)...

BACKGROUND: The aim of fluid resuscitation is to increase stroke volume, yet this effect is observed in only 50% of patients. Prediction of fluid responsiveness may allow fluid resuscitation to be administered to those most likely to benefit. The aim of this study was to systematically review the test characteristics of respiratory variation in inferior vena cava (IVC) diameter as a predictor of fluid responsiveness in patients with acute circulatory failure. METHODS: Electronic searches combined with reference review of identified studies...

Despite the application of numerous supplements to improve in vitro culture (IVC) conditions of mammalian cells, studies regarding the effect of fetal bovine serum (FBS) on mammalian early embryogenesis, particularly in relation to redox homeostasis, are lacking. Herein, we demonstrated that early development of in vitro-produced (IVP) porcine embryos highly depends on the combination of FBS supplementation timing and embryonic reactive oxygen species (ROS) requirements. Interestingly, FBS significantly reduced intracellular ROS levels in parthenogenetically activated (PA) embryos regardless of the developmental stage...

BACKGROUND: The prognosis of advanced liver malignancy with inferior vena cava (IVC) thrombi is poor. Many therapeutic policies are challenging for long-term prognosis. We performed the modified effective technique of transdiaphragmatic intrapericardial IVC isolation for curative resection of IVC tumors and prolonged survival time. METHODS: Between 2003 and 2015, 10 patients, sustained liver malignancy with IVC thrombi, underwent surgical intervention. Liver resection with thrombectomy under total hepatic vascular exclusion via the transdiaphragmatic intrapericardial IVC isolation method was performed for these 10 patients...

This study investigated the effects of early induction of autophagy on embryonic development in pigs. For this, oocytes or embryos were treated with an autophagy inducer, rapamycin (RP), during post-activation (Pa), in vitro fertilization (IVF) and/or in vitro culture (IVC). When parthenogenesis (PA) embryos were untreated (control) or treated with various concentrations of RP for 4 hr during Pa, 100 nm RP showed a higher blastocyst formation (48.8 ± 2.7%) than the control (34.6 ± 3.0%). When PA embryos were treated during the first 24 hr of IVC, blastocyst formation was increased (p < ...
