Portal vein thrombosis (PVT) is common in patients with cirrhosis undergoing transjugular intrahepatic portosystemic shunt (TIPS). This study had 3-fold aims: to assess risk factors for PVT; to determine the efficacy of anticoagulant therapy; to investigate the impact of PVT on clinical outcomes in TIPS-treated cirrhosis.Between June 2012 and February 2016, 126 TIPS-treated patients with cirrho...
Occlusive PVT concurrent with chronic liver disease is a common clinical entity among pediatric patients referred for transplantation. The natural history of PVT is unknown. Our aim was to determine, using a retrospective cohort design, if children under 13 yr with chronic liver disease and concomitant PVT have an increased mortality risk prior to and after transplantation. A total of 203 patie...
خلاصهسابقه و هدف: بیماران تالاسمی که تحت ترانسفوزیون خون قرار میگیرند، در صورت نیاز به بیش از 20 سی سی خون به ازای هر کیلو گرم وزن بدن، نیاز به طحالبرداری دارند. یکی از عوارض خطرناک و کشنده در بیماران طحالبرداری شده ترومبوز ورید پورت (Portal Vein Thrombosis, PVT) میباشد. پیگیری این بیماران برای تشخیص به موقع PVT و درمان مناسب آن نقش مهمی در بقای این بیماران دارد. این مطالعه به منظور بررسی فرا...
BACKGROUND AND AIMS Most portal vein thromboses (PVT) in cirrhotics are discovered incidentally. While case series demonstrate improved portal vein patency with anti-coagulation, there is little information on impact of PVT on morbidity and mortality. This study aimed to compare morbidity and mortality in cirrhotics with untreated PVT with those without PVT. MATERIAL AND METHODS Cirrhotics ev...
In this study, we evaluated the sensitivity of a 5-min personal digital assistant-psychomotor vigilance test (PDA-PVT) to severe sleep loss. Twenty-one participants completed a 10-min PVT-192 and a 5-min PDA-PVT at two hourly intervals during 62 h of sustained wakefulness. For both tasks, response speed and number of lapses (RTs > 500) per minute significantly increased with increasing hours of...
LAMOND N, DAWSON D, ROACH GD. Fatigue assessment in the field: validation of a hand-held electronic psychomotor vigilance task. Aviat Space Environ Med 2005; 76:486–9. Introduction: In recent years, there has been an increasing need for a reliable and practical tool for assessing fatigue-related impairment in the field. This study investigated the sensitivity of one potential tool, a 5-min vers...
Chromosomal translocations in Burkitt lymphoma and mouse plasmacytomas typically lie within or near the protooncogene MYC. In some instances, however, these tumors contain variant translocations with breakpoints located more distant from and downstream of MYC, in a domain commonly known as pvt-1. Until now, there has been no evidence that pvt-1 marks the location of a functional gene. Here we r...
Background & Aims. It is unclear whether portal vein thrombosis (PVT) unrelated to malignancy is associated with reduced survival or it is an epiphenomenon of advanced cirrhosis. The objective of this study was to assess clinical outcome in cirrhotic patients with PVT not associated with malignancy and determine its prevalence. MATERIAL AND METHODS Retrospective search in one center from Jun...
The lack of effective pharmacotherapies to prevent relapse to drug taking emphasizes the importance of fully characterizing the brain pathways responsible for this behavior (Kalivas and McFarland, 2003). Recently, there have been attempts to more fully understand the brain circuitry responsible for drug-seeking behavior, beyond the well-characterized nodes such as the prefrontal cortex (PFC), n...
BACKGROUND Thrombolysis (T) is an effective therapy for prosthetic valve thrombosis (PVT). Debate still exists as to which clinical or noninvasive finding best predict the result of T. The aim of the study was to investigate the role of fluoroscopy (F) to predict efficacy of T in pts with mitral PVT. METHODS We evaluated 17 consecutive pts with bileaflet mitral PVT. F criteria for PVT were: a...
