Prognostic Factors, Incidence and Management for Acute Variceal Bleeding in the Liver Transplantation Era

Surgical Science 2011年第4期2卷 198-203页

Background: Gastroesophageal varices are the most common and clinically important part of the portosys-temic collaterals due to their tendency to rupture and cause massive gastrointestinal bleeding. Objective The aim of this work was to evaluate retrospectively the incidence and the factors of prediction for the treatment of bleeding by gastroesophageal varices in the patients attended in the Emergency Room of the Hospital State University of Campinas (Brazil) from the last ten years. Methods: The method used here consisted of a descriptive and retrospective study carried out from the analyses of the medical records of 769 patients with upper gastrointestinal bleeding of which 220 were admitted because of upper gastrointestinal bleeding caused by gastroesophageal varices during this same period. Results: The results showed that the gastroe-sophageal varices appeared in 28.6% of the patients and they were the second most common cause of upper gastrointestinal bleeding. While evaluating factors such as age, sex and the common individual records, it was proved that this disease occurs mainly among people between the third and the fifth decade of life, with the great majority of cases occurring in the fourth decade (29.2%), of which 76.8% were male. There was an association of hematemesis and melena in the admission of 57.7% of the patients and even ascites was a common diagnosis in 48.2% of them. Most of these patients (40%) were classified as Child class B at admis-sion. The early endoscopic exam was used for 96.8% of them and showed the presence of F3 varices in 38.5%, CB varices in 25.1% and RCS varices in 12.6%. Most of these varices (41.5%) were situated in the distal third of the esophagus. The most used pharmacological treatment was based on octreotide in 45.9% of the patients. They received 0.05 mg of intravenous octreotide and a maintenance dose of 1 mg per day in 98.6% of the cases, with efficacy in 74.2% of the patients. The tamponade with Sengstaken-Blakemo

Dear editor:We sincerely thank Matthew *** for his insightful commentary1 on our recent publication in the Journal of Sport and Health Science.2 Clarkson's pioneering work in the development and application of blood flow restriction (BFR) exercise protocols has undeniably laid the groundwork for subsequent investigations in this field,including our own.(3-6)His commentary not only highlights the relevance and timeliness of our study but also offers valuable perspectives on refining safety considerations for intradialytic BFR exercise among hemodialysis patients.

Sensors Applied to Plant Breeding: Leaf Reflectance Indices (LRIs) and Resistance to Anthracnose in Capsicum annuum L. var. annuum

引用

Advances in Remote Sensing 2024年第1期13卷 1-17页

作者： Rosimara Barboza Bispo Maria Do Socorro Bezerra Araújo Antônio André da silva Alencar Cláudia Pombo Sudré Rosana rodrigues Plant Breeding Laboratory Darcy Ribeiro North Fluminense State University Campos dos Goytacazes Brazil Plant Breeding Laboratory University of the State of Mato Grosso Cáceres Brazil

The present work investigated the efficiency of leaf reflectance indices in the identification of Capsicum annuum L. var. annuum resistant to anthracnose in the fruit. Twenty-five F5:6 families originating from contrasting parents were assessed;the parents were accession UENF 2285 (susceptible to anthracnose) and accession UENF 1381, a hot pepper resistant to anthracnose in the fruit. The experiment was carried out in an experimental field in Campos dos Goytacazes, Rio de Janeiro, Brazil, between May and October of 2021. The treatments were arranged in a randomized block design, with three replications and five plants per plot. Fifteen LRIs were estimated using a CI-710 portable mini leaf spectrometer. The assessments covered all plant growth after flowering, and a total of six assessments were performed at 15-days intervals, beginning at 35 and ending 120 days after flowering (daFs). Analysis of variance in a split-plot scheme was performed, as were tests of mean groupings and principal components analysis (PCA). The best period for evaluating leaf reflectance indices in C. annuum var. annuum is 120 days after flowering. The leaf reflectance indices PRI, CNDVI and Ctr2 stood out as effective in distinguishing between resistant and susceptible genotypes.
