AbstractPortal vein thrombosis (PVT) is a rare condition, and malignancies account for up to a quarter of cases. Malignant PVT is an advanced stage in the neoplastic process, which affects survival. In addition, portal venous obstruction can result in portal hypertension and associated complications. There are a few reports on the surgical and nonsurgical management of this condition. We herein aim to present an overview of these management options and discuss the factors affecting the outcomes after each. We will also discuss gaps in knowledge and the possible areas for future research.

SummaryA high incidence of post-discharge venous thromboembolism in orthopaedic surgery patients has been recently reported drawing further attention to the unresolved issue of the optimal duration of the pharmacological prophylaxis. We performed an overview analysis in order to evaluate the incidence of late occurring clinically overt venous thromboembolism in major orthopaedic surgery patients discharged from the hospital with a negative venography and without further pharmacological prophylaxis. We selected the studies published from January 1974 to December 1995 on the prophylaxis of venous thromboembolism after major orthopaedic surgery fulfilling the following criteria: 1) adoption of pharmacological prophylaxis, 2) performing of a bilateral venography before discharge, 3) interruption of pharmacological prophylaxis at discharge in patients with negative venography, and 4) post-discharge follow-up of the patients for at least four weeks. Out of 31 identified studies, 13 fulfilled the overview criteria. The total number of evaluated patients was 4120. An adequate venography was obtained in 3469 patients (84.1%). In the 2361 patients with negative venography (68.1%), 30 episodes of symptomatic venous thromboembolism after hospital discharge were reported with a resulting cumulative incidence of 1.27% (95% C.I. 0.82-1.72) and a weighted mean incidence of 1.52% (95% C.I. 1.05-1.95). Six cases of pulmonary embolism were reported. Our overview showed a low incidence of clinically overt venous thromboembolism at follow-up in major orthopaedic surgery patients discharged with negative venography. Extending pharmacological prophylaxis in these patients does not appear to be justified. Venous thrombi leading to hospital re-admission are likely to be present but asymptomatic at the time of discharge. Future research should be directed toward improving the accuracy of non invasive diagnostic methods in order to replace venography in the screening of asymptomatic post-operative deep vein thrombosis.

Consumer behavior research seems to play an big role in determining the wants and needs of an industry. This research helps to shape the way we market to the consumers and helps make marketing strategies more effective. In the 1950s grocery stores began to sell horticulture products in order to alleviate the growers' surplus. Supermarkets now have seem to found their niche in this market due to the fact that they can influence their consumers to buy their flowers right along with their bread, and get all of their shopping done at once. This new type of sale, commonly referred to as the impulse sale, can relate directly to how well the store is merchandised and maintained. A study was conducted at a local supermarket, to determine the following: good locations for impulse sales items, special conditions affecting impulse sales items, and what types of things could affect demand for impulse items. It was discovered that certain locations make better sales than other locations. Locations that were front and center and allowed easy access to seeing the mixed flower bouquet without having to touch it yielded the best results. The variables used to show a change in demand showed little to some variability and has raised some questions which may be used to conduct future research.

Abstract Background Phony peach disease (PPD) is caused by the plant pathogenic bacterium Xylella fastidiosa subsp. multiplex (Xfm). Historically, the disease has caused severe yield loss in Georgia and elsewhere in the southeastern United States, with millions of PPD trees being removed from peach orchards over the last century. The disease remains a production constraint, and management options are few. Limited research has been conducted on PPD since the 1980s, but the advent of new technologies offers the opportunity for new, foundational research to form a basis for informed management of PPD in the U.S. Furthermore, considering the global threat of Xylella to many plant species, preventing import of Xfm to other regions, particularly where peach is grown, should be considered an important phytosanitary endeavor. Main topics We review PPD, its history and impact on peach production, and the eradication efforts that were conducted for 42 years. Additionally, we review the current knowledge of the pathogen, Xfm, and how that knowledge relates to our understanding of the peach—Xylella pathosystem, including the epidemiology of the disease and consideration of the vectors. Methods used to detect the pathogen in peach are discussed, and ramifications of detection in relation to management and control of PPD are considered. Control options for PPD are limited. Our current knowledge of the pathogen diversity and disease epidemiology are described, and based on this, some potential areas for future research are also considered. Conclusion There is a lack of recent foundational research on PPD and the associated strain of Xfm. More research is needed to reduce the impact of this pathogen on peach production in the southeastern U.S., and, should it spread internationally, wherever peaches are grown.

AbstractIntroduction: We describe a technique we call “Meso-transjugular intrahepatic portosystemic shunt (MTIPS)” for relief of portal hypertension secondary to portal vein thrombosis (PVT) using combined surgical and endovascular technique. Materials and Methods: Nine adult patients with PVT underwent transjugular intrahepatic portosystemic shunt through a combined transjugular and mesenteric approach (MTIPS), in which a peripheral mesenteric vein was exposed through a minilaparotomy approach. The right hepatic vein was accessed through a transjugular approach. Mechanical thrombectomy, thrombolysis, and angioplasty were performed when feasible to clear PVT. Results: All patients had technically successful procedures. Patients were followed up for a mean time of 13.3 months (range: 8 days to 3 years). All patients are still alive and asymptomatic. Conclusion: We conclude that MTIPS is effective for the relief of portal hypertension secondary to PVT.

Введение. Тромбозы глубоких вен (ТГВ) являются нередким осложнением течения и лечения у детей с заболеваниями крови и требуют проведения антитромботической терапии и профилактики для снижения количества повторных тромботических эпизодов. Цель исследования: анализ частоты и определение факторов риска повторных ТГВ у детей, госпитализированных для лечения заболеваний крови. Материалы и методы. Проведен ретроспективный анализ электронной базы данных пациентов в возрасте от 0 до 17 лет включительно, которым проводили стационарное лечение гемобластозов и синдромов костномозговой недостаточности в период 01.0.2012 по 31.12.2017. В анализ вошли только те пациенты, у которых было зарегистрировано более 1 случая тромбоза. Результаты. Рецидивы тромбозов наблюдали у 13,3 детей с асимптоматическими (аТГВ) и у 5,4 с симптоматическими (сТГВ) ТГВ. Рецидивы аТГВ при остром лимфобластном лейкозе (ОЛЛ) выявлены у 14,5, при остром миелобластном лейкозе (ОМЛ) у 8,9, при лимфоме у 11,9. У детей с сТГВ рецидивы тромбоза выявлены при ОЛЛ у 8,2, при ОМЛ у 8,3, при лимфоме у 2,8 пациентов. Медиана возраста пациентов с единственным эпизодом сТГВ составила 10 лет, с рецидивом сТГВ 9 лет, при аТГВ 7 лет для пациентов с единственным эпизодом и 6 лет с рецидивом аТГВ. Некорректно проведенная терапия была зарегистрирована у 50 детей. Заключение. Рецидивирующее течение тромбоза у детей, госпитализированных для лечения заболеваний крови, уста новлено у 5,4 детей с сТГВ и у 13,3 детей с аТГВ, причем 1/3 часть сТГВ является потенциально жизнеугрожающей. Полученные данные подчеркивают необходимость проведения вторичной антитромботической профилактики у детей с ТГВ и ставят вопрос о необходимости и целесообразности проведения таковой у пациентов с аТГВ. Introduction. Deep vein thrombosis (DVT) remains a common complication of hematological diseases in children and requires antithrombotic therapy and prophylaxis of recurrent thrombotic events. Aim: to determine incidence and risk factors of recurrent DVT for hospitalized children with blood diseases. Materials and methods. Medical records of patients hospitalized with oncohematological diseases and bone marrow aplasia, aged from 0 to 17 years, were analyzed retrospectively. Only patients with more than one DVT were taken into this analysis. Results. Recurrent DVT was diagnosed in 13.27 children with asymptomatic DVT (aDVT) and in 5.41 with symptomatic DVT (sDVT). Recurrent DVT was found in 14.49 children with acute lymphoblastic leukemia (ALL), in 8.89 with acute myeloblastic leukaemia (AML), in 11.86 with lymphomas. Incidence of recurrent thrombosis in children with sDVT was 8.16 for ALL, 8.33 for AML, 2.78 for lymphomas. Age analysis of patients with the single episode and recurrent thrombosis showed that age median with single sDVT was 10 years, recurrent DVT 9 years, in case of single asymptomatic or incidental (aDVT) episode 7 years, recurrent DVT 6 years. Incorrect therapy was registered for 50 of children with recurrent sDVT. Conclusion. Recurrent DVT in hospitalized children with blood diseases occurred in 5.41 children with sDVT and in children 13.33 with aDVT 1/3 episodes of sDVT was lifethreatening. In conclusion, secondary prophylaxis is needed for children with DVT and future research should be done for prophylaxis in those with aDVT.

Superior ophthalmic vein thrombosis is extremely rare and is often associated with orbital inflammation/infection, systemic/local tumors, hypercoagulable states, autoimmune conditions, and rarely carotid cavernous fistula. Clinical features include abrupt onset of painful proptosis, chemosis, ophthalmoplegia, and diminished visual acuity. Prompt diagnosis and treatment are essential to prevent permanent blindness. Management options for this medical emergency include antibiotics, steroids, and/or anticoagulation. We present a case of superior ophthalmic vein thrombosis with left cavernous sinus thrombosis in the setting of newly diagnosed malignancy.

ObjectiveLimited data are available on the prevention of variceal rebleeding in cirrhotic patients with portal vein thrombosis (PVT). This study aimed to compare transjugular intrahepatic portosystemic shunt (TIPS) with covered stents versus endoscopic band ligation (EBL) plus propranolol for the prevention of variceal rebleeding among patients with cirrhosis and PVT.DesignConsecutive cirrhotic patients (94% Child-Pugh class A or B) with PVT who had variceal bleeding in the past 6 weeks were randomly assigned to TIPS group (n=24) or EBL plus propranolol group (EBL+drug, n=25), respectively. Primary endpoint was variceal rebleeding. Secondary endpoints included survival, overt hepatic encephalopathy (OHE), portal vein recanalisation and rethrombosis, other complications of portal hypertension and adverse events.ResultsDuring a median follow-up of 30 months in both groups, variceal rebleeding was significantly less frequent in the TIPS group (15% vs 45% at 1 year and 25% vs 50% at 2 years, respectively; HR=0.28, 95% CI 0.10 to 0.76, p=0.008), with a significantly higher portal vein recanalisation rate (95% vs 70%; p=0.03) and a relatively lower rethrombosis rate (5% vs 33%; p=0.06) compared with the EBL+drug group. There were no statistically significant differences in survival (67% vs 84%; p=0.152), OHE (25% vs 16%; p=0.440), other complications of portal hypertension and adverse events between groups.ConclusionCovered TIPS placement in patients with PVT and moderately decompensated cirrhosis was more effective than EBL combined with propranolol for the prevention of rebleeding, with a higher probability of PVT resolution without increasing the risk of OHE and adverse effects, but this benefit did not translate into improved survival.Trial registration numberClinicalTrials.gov: NCT01326949.
