Portal vein thrombosis (PVT) was for a long time considered a barrier to liver transplantation. The aim of this study is to demonstrate the surgical technical options for portal vein reconstruction during liver transplantation in patients with PVT in which thrombectomy was not possible. Between September 1991 and March 2009, 420 liver transplanted patients were retrospectively analyzed, identifying 29 cases with PVT (6.9%). Preoperative diagnosis, preoperative risk factors, surgical technique options to treat various forms (grades) of PVT, postoperative recurrence and actuarial survival rates were studied. In three cases of PVT grade II and in one case PVT grade III the thrombectomy was insufficient, requiring some surgical technique options (13.79%). In two cases placement of iliac vein graft was performed, in one an anastomosis of the portal vein with collateral splenorenal vein and in the other with left gastric varicose. The actuarial survival rate for patients without PVT and patients with PVT and effective thrombectomy was 73.8% while those with PVT who needed some type of surgical option was 75%. Our results suggest that actuarial survival rates were similar among patients with PVT or PVT with effective thrombectomy when compared with PVT that required some surgical options.

The increasing volume of data in the area of environmental sciences needs analysis and interpretation. Among the challenges generated by this “data deluge”, the development of efficient strategies for the knowledge discovery is an important issue. Here, statistical and tools from computational intelligence are applied to analyze large data sets from meteorology and climate sciences. Our approach allows a geographical mapping of the statistical property to be easily interpreted by meteorologists. Our data analysis comprises two main steps of knowledge extraction, applied successively in order to reduce the complexity from the original data set. The goal is to identify a much smaller subset of climatic variables that might still be able to describe or even predict the probability of occurrence of an extreme event. The first step applies a class comparison technique: p-value estimation. The second step consists of a decision tree (DT) configured from the data available and the p-value analysis. The DT is used as a predictive model, identifying the most statistically significant climate variables of the precipitation intensity. The methodology is employed to the study the climatic causes of an extreme precipitation events occurred in Alagoas and Pernambuco States (Brazil) at June/2010.

AIM: To compare the ability of model for end-stage liver disease(MELD)-Na and Maddrey discrimination function index(DFI) to predict mortality at 30 and 90 d in patients with alcoholic hepatitis(AH).METHODS: We prospectively assessed 52 patients with AH. Demographic, clinical and laboratory parameters were obtained. MELD-Na and Maddrey DFI were calculated on admission. Short-term mortality was assessed at 30 and 90 d. Receiver operating characteristic curve analysis was performed. RESULTS: Thirty-day and 90-d mortality was 44% and 58%, respectively. In the univariate analysis, sodium levels was associated with mortality at 30 and 90 d(P = 0.001 and P = 0.03). Child stage, encephalopathy, ascites, or types of treatment were not associated with mortality. MELD-Na was the only predictive factor for mortality at 90 d. For 30-d mortality area under the curve(AUC) was 0.763(95%CI: 0.63-0.89) for Maddrey DFI and 0.784 for MELD-Na(95%CI: 0.65-0.91, P = 0.82). For 90-d mortality AUC was 0.685(95%CI: 0.54-0.83) for Maddrey DFI and 0.8710 for MELD-Na(95%CI: 0.76-0.97, P = 0.041). CONCLUSION: AH is associated with high shortterm mortality. Our results show that MELD-Na is a more valuable model than DFI to predict short-term mortality.

The adoption by health professionals to the practice of patient isolation is a decision that reduces patients’ risks of occupational exposure to potentially contaminated biological material and prevents nosocomial infections. Verify the compliance of health professionals to the practices of contact precautions in patients colonized by microorganisms in a teaching hospital. This was a prospective observational cohort study in a special-sized hospital located in southeastern Brazil. The observation of health professionals in delivery of health care to patients with contact precaution was performed regarding hand hygiene, use of overcoat, glove, and mask. We carried out 1502 observations involving the following professional categories: nursing technicians and/or nursing assistants (n = 1028;68.4%), nurses (n = 200;13.3%), physical therapists (n = 185;12.3%), and physicians (n = 89;5.9%), totaling 971.8 hours. Regarding the level of compliance of professionals to contact precaution practices with hand hygiene after the procedures, the use of overcoats, gloves, and masks, all were statistically significant (p Klebsiella pneumoniae was the most positive pathogen identified in laboratory tests. This study provided the mapping of the compliance of health professionals to the practices of contact precautions in order to support a safer management of patient care reducing the risks of Healthcare-Associated Infections (HAI). This study also showed that health professionals are using practice management to deal with their behavior to protect their health.

Background: Cardiac involvement and the consequences of inflammation induced by SARS-CoV2 infection could have catastrophic long-term consequences. Left ventricular mechanics could identify a specific pattern of myocardial fiber damage in patients infected with COVID-19. To our knowledge there are no publications referring to the global description of ventricular mechanics in patients with COVID-19. Objective: To describe left ventricular mechanics in hospitalized patients with COVID-19. Methods: In this cross-sectional study, we included 40 hospitalized patients with confirmed diagnostic of COVID-19, from April 11, 2020, to September 6, 2020. Demographic and laboratory data, clinical and echocardiographic characteristics were collected, as well as events during hospitalization. Left ventricular deformation was analyzed and reported. Results: Subclinical dysfunction was observed in 82.5% (left ventricular longitudinal strain [LVGLS] -17.05% and global circumferential strain [GCS] -18.6%) of the patients, likewise, the mean twist and apical rotation were preserved, and even increased as part of the compensating mechanism to maintain the ejection fraction. Conclusion: In patients hospitalized with COVID-19, despite having a normal left ventricular ejection fraction, subclinical myocardial damage was found, manifested by a decrease in Global Longitudinal Strain (GLS) and Global Circumferential Strain (GCS). This behavior is similar to that of cardiomyopathies in the early stage of the disease, and given the pathophysiological mechanisms involved in the disease, its long-term consequences should be monitored and evaluated.

The genetic diversity from species of the genus Jatropha collected from Costa Rica was analyzed by AFLP (amplified fragments length polymorphism). The study consisted of 114 accessions from 15 populations of 4 different species: J. curcas, J. costaricensis, J. gossypifolia and J. stevensii. These were collected from different locations in Costa Rica. Three different primers were used, resulting in 428 loci, and they were classified in three categories: unique and double bands (UBD), rare bands (RB) and shared bands (SB). The UBD were excluded for a total of 339 polymorphic loci used for the UPGMA dendrogram and principal component analysis (PCA). The species that obtained the highest average of polymorphic loci was J. curcas, which obtained the highest percentage of polymorphic loci (80.24%), followed by J. gossypifolia (79.35%), J. costaricensis (78.76%), and finally J. stevensii (40.71%). The average for the polymorphic loci was of 69.76%. Thus, the phylogeny of the Jatropha species in Costa Rica was elucidated, showing J. curcas more related to J. stevensii and this one with J. costaricensis, and J. gossypifolia as the most distant member of the genus. For the best of our knowledge this is the first report of a genetic analysis of J. costaricensis and J. stevensii. The obtained molecular evidence showed high levels of polymorphisms in the present study compared with reports from Africa, India, and China. The molecular diversity estimated in our analysis, together with agronomical or morphological data, can be very useful for plant breeding programs, given the importance of Jatropha species in oil production. Interestingly, Central American Jatropha material can be used to increase the genetic base of J. curcas populations localized in Asia and Africa, where reduced genetic diversity has been reported.

The main goal is to compare the antioxidant potential of rosemary and oregano natural extracts in precooked beef burger by assessing the lipid oxidation extent and sensory analysis. Five formulations (F) of hamburger were prepared from beef and mechanically separated as follows: meat containing sodium erythorbate (F1);deodorized rosemary extract (F2);oregano extract (F3);rosemary plus oregano extracts (F4) and without antioxidant addition, denominated control formulation (CF). The samples were frozen at ?18°C for 24 hours, then submitted to heat treatment in an electric oven with internal controlled temperature of 75°C, and again frozen for a period of 30 days. The lipid oxidation extent (determined by thiobarbituric acid reactive substances— TBRS) was evaluated at 0, 15 during 30 days. After heating in plate to temperature of 75°C, the samples were submitted to color, taste and odor evaluation by 40 untrained tasters. The formulations F1, F2 and F4 presented lower concentrations of TBRS, whereas CF at day zero already showed very high values, indicating oxidation of the product. The samples showed good acceptance in the sensorial analysis.
