BACKGROUND: Upper gastrointestinal bleeding (UGIB) is a common condition in gastroenterology, but "Downhill Varices" (DHV) or varices of the upper oesophagus are an uncommon cause of UGIB, with different aetiology from lower third oesophageal varices and different therapeutic implications. CASE REPORT: A 28-year-old male patient, with a history of chronic kidney failure secondary undergoing haemodialysis and superior vena cava syndrome (SCVS) due to multiple catheter replacements, was admitted to the Emergency Department with haematemesis secondary to a varicose vein rupture in the proximal third of oesophagus, treated initially with ethanolamine...

MicroRNAs (miRNAs) have been identified as a new class of regulatory molecules that influence many biological functions, including metabolism, adipocyte differentiation. To determine the role of adipogenic miRNAs in the adipocyte differentiation process, we used microarray technology to monitor miRNA levels in human adipose-derived mesenchymal stem cells (hMSCs-Ad), human stromal vascular cells (SVCs) and differentiated adipocytes. 79 miRNAs were found to be differentially expressed, most of which are located in obesity related chromosomal regions but have not been previously linked to adipocyte differentiation process...

Superior vena cava syndrome (SVCS) is a relatively common sequela of mediastinal malignancies and may cause significant patient distress. SVCS is a medical emergency if associated with laryngeal or cerebral edema. The etiologies and management of SVCS have evolved over time. Non-malignant SVCS is typically caused by infectious etiologies or by thrombus in the superior vena cava and can be managed with antibiotics or anti-coagulation therapy, respectively. Radiation therapy (RT) has long been a mainstay of treatment of malignant SVCS...

Seminal vesicle cysts (SVCs) associated with other genitourologic abnormalities are rare. Often associated with ipsilateral renal agenesis in a symptomatic patient. In symptomatic patients open surgical excision is the treatment of choice. The laparoscopic approach is a less invasive option. Recently robot-assisted management has gained a primary role for the treatment of this condition.

The Azerbaijan State Veterinary Control Service (SVCS) has conducted active serological surveillance for avian influenza (AI) in poultry since 2006, when the first outbreak of AI H5N1 occurred in Azerbaijan. Samples are collected from September to May annually and tested using a hemagglutination inhibition (HI) assay to detect antibodies against H5 AI viruses. HI testing is also performed for Newcastle disease virus (NDV) upon request, but since this method cannot distinguish between natural infections and immune responses to vaccination, all positive results require follow-up epidemiological investigations...

Lipomatous hypertrophy of the interatrial septum (LHIS) is an uncommon cause of superior vena cava syndrome (SVCS). Fibrosing mediastinal lymphadenopathy is another cause of SVCS. We present a 65-year-old female patient with a history of tuberculosis (TB) and the coexistence of LHIS and fibrosing mediastinitis due to TB of the lung. Fibrosing or sclerosing mediastinitis is a rare entity with few cases published in the western literature. She presented with mild symptomatology of SVCS and she underwent on transthoracic and transesophageal echocardiography, computed tomography scan, magnetic resonance imaging, and venography...

The treatment of some subsets of patients having both right-sided superior vena cava (SVC) and left-sided SVC may be very challenging. We performed the SVC integration (SVCI) technique with end-to-side anastomoses between the two SVCs on 4 such patients (age, 5 to 11 months; body weight, 5.4 to 10.2 kg) with excellent outcomes. In 2 patients, we performed intrapulmonary artery septation with SVCI; in 1 patient, pulmonary artery sling repair with SVCI; and in 1 patient with supramitral stenosis related to persistent left-sided SVC, repeated Blalock-Taussig shunt (BTS) with SVCI...

In this study, an optimisation of extraction of sulphur volatile compounds (SVCs) has been performed using Central Composite Design. The conditions of the highest amount of eluated peaks and total peaks area have been treated. Factors such as coating of fiber for SPME (Solid Phase Microextraction), extraction temperature and extraction time have been optimised. The SVCs have shown the optimal extraction using a DVB/CAR/PDMS (divinylbenzene/carboxen/polydimethylsiloxane) fiber at 73 °C during 50 min. Furthermore, a pre-incubation step lasting 20 min at the extraction temperature has been used...

AIM: Vascular access (VA) dysfunction limits hemodialysis delivery, which increases morbidity and mortality. The most com mon cause of VA failure is thrombosis, due to flow limiting stenosis resulting from neointimal hyperplasia. This occurs not only due to hemodynamic factors but also by systemic ones related to vascular atherosclerosis, inflammation and calcification, which has developed a simple vascular calcification score (SVCS) predictor of vascular calcification and arterial stiffness...

INTRODUCTION: Substernal goiter may rarely cause superior vena cava syndrome (SVCS) owing to venous compression, and cause acute respiratory failure due to tracheal compression. Obstructive sleep apnea syndrome (OSAS) may rarely occur when there is a narrowing of upper airway by edema and vascular congestion resulting from SVCS. CASE PRESENTATION: We presented the clinical course and treatment of acute respiratory failure (ARF) developed in a patient with SVCS and OSAS due to substernal goiter...

Approximately 10% of small cell lung cancer (SCLC) cases develop superior vena cava syndrome (SVCS). Many SCLC patients with SVCS have relatively limited disease, requiring curative rather than palliative treatment. Besides chemotherapy, radiotherapy is important for treating SCLC with SVCS. We retrospectively evaluated the influence of radiotherapy dose on the prognosis of 57 patients with SCLC with SVCS treated with concurrent chemoradiotherapy. The mean biological equivalent radiation dose was 71.5 Gy. We administered etoposide/cisplatin as sequential and concurrent chemotherapy...

BACKGROUND: Superior vena cava syndrome (SVCS) is the result of the direct obstruction of the superior vena cava by malignancy and/or mediastinal lymphadenopathy. Our aim is to propose a diagnostic algorithm for undiagnosed superior vena cava syndrome patients and compare the diagnostic value, mortality and morbidity rates in patients diagnosed by mediastinoscopy. METHODS: Ninety-seven patients with SVCS underwent diagnostic management starting with the least invasive technique and proceeding to more advanced and invasive methods between January 2000 and June 2013...

BACKGROUND: Low superior vena cava (SVC) blood flow has recently been identified as a marker for bidirectional superior cavopulmonary connection (SCPC) failure and death. Prior innominate vein occlusion is considered a significant anatomic risk factor for SCPC failure. We therefore evaluated the outcomes of infants who underwent SCPC with known upper-body venous obstruction. METHODS: Between February 1995 and June 2014, SCPC was carried out in 8 patients who had either a single SVC with known prior occlusion of the innominate vein (n = 6) or bilateral SVCs without a bridging vein with occlusion of one SVC (n = 2)...

BACKGROUND: Obese patients display differences in vancomycin drug disposition, which may complicate attainment of appropriate serum vancomycin concentrations (SVCs). This study was conducted to determine if obesity leads to trough SVCs above the therapeutic range. METHODS: This retrospective cohort study sought to determine the rate and predictors of high (i.e. >20 mg/L) serum trough levels according to level of obesity. RESULTS: Increasing BMI predicted SVCs > 20 mg/L after controlling for dose, age, and serum creatinine...

OBJECTIVE: Inflammation is critical for the development of obesity-associated metabolic disorders. This study aims to investigate the role of mitogen-activated protein kinase phosphatase 2 (MKP-2) in inflammation during macrophage-adipocyte interaction. METHODS: White adipose tissues (WAT) from mice either on a high-fat diet (HFD) or normal chow (NC) were isolated to examine the expression of MKP-2. Murine macrophage cell line RAW264.7 stably expressing MKP-2 was used to study the regulation of MKP-2 in macrophages in response to saturated free fatty acid (FFA) and its role in macrophage M1/M2 activation...

Obesity is accompanied by chronic inflammation of VAT, which promotes metabolic changes, and purinergic signaling has a key role in a wide range of inflammatory diseases. Therefore, we addressed whether fat inflammation could be differentially modulated by this signaling pathway in the MUO and in individuals who remain MHO. Our results show that the necrotized VAT of both groups released greater levels of ATP compared with lean donors. Interestingly, MUO tissue SVCs showed up-regulation and engagement of the purinergic P2X7R...

Among juvenile offenders, those who commit the greatest number and the most violent offenses are referred to as serious, violent, and chronic (SVC) offenders. However, current practices typically identify SVC offenders only after they have committed their prolific and costly offenses. While several studies have examined risk factors of SVCs, no screening tool has been developed to identify children at risk of SVC offending. This study aims to examine how effective the adverse childhood experiences index, a childhood trauma-based screening tool developed in the medical field, is at identifying children at higher risk of SVC offending...
