Late Follow-up Of Gastrectomized Patients For Peptic Ulcer: Clinical, Endoscopic And Histopathological Aspects [avaliação Tardia De Doentes Gastrectomizados Por úlcera Péptica: Aspectos Clínicos, Endoscópicos E Histopatológicos]

Background - The gastrectomy is an uncommon procedure because the proton bomb inhibitors associated to the antibiotic outlines used to eradicate the Helicobacter pylori changed the focus of the peptic ulcer treatment. Aims - Later evaluation on those patients who underwent partial gastrectomy as a treatment for peptic ulcer, at that time when any drug to eradicate the Helicobacter pylori was not used. The clinical evaluation included the late postoperative symptoms and postgastrectomy syndromes like dumping, diarrhea, alkaline gastritis and nutritional aspects. The upper digestive endoscopy analysed the surgery reconstruction and the gastric stump, the duodenum and the jejunum mucosa aspects. The histopathological evaluation included looking for Helicobacter pylori by using two different methods: histology and urease test. Casuistic and Methods - Fifty-nine patients, 44 (74.6%) male, median age 55.5 years old (range from 31 to 77 years old), who underwent a clinical interview and an upper digestive endoscopy. Paraffin blocks from the surgical specimen were reviewed in order to find out if the patients did have or did not have Helicobacter pylori before surgery. Results - The final results show that most of the patients had very good and good clinical evolution (Visick I e II) in 96%. The most common symptoms on late postoperative are mild dyspepsia with or without Helicobacter pylori, and diarrhea, anemia and dumping occurred in, respectively, 11 (18.6%), 2 (3.4%) and 2 (3.4%) cases. The Billroth I reconstruction had the best clinical results on statistical rate. The endoscopic finding showed normal results in the most number of cases, and reflux alkaline gastritis or erosive gastritis in a few cases. Ulcer recurrences were diagnosed in two patients (3.4%), and both had positive Helicobacter pylori. Most of the patients had Helicobacter pylori (86%) before surgery and also in the postoperative time (89.9%). Conclusions - The patients had a very good clinical evolution after the gastrectomy. The Billroth I reconstruction had the best clinical results. The Helicobacter pylori is still present on gastric stump in late postoperative time, and we believe that it does not bring any negative influence to surgical results.423146152Andreollo, N.A., (1994) Contribuição à Etiologia do Câncer do Coto Gástrico - Estudo Experimental, , [tese].

Presença de Campylobacter spp. em macacos-de-cheiro (Saimiri spp.) assintomáticos cativos e sua correlação com as condições de manejo Campylobacter spp. in asymptomatic captive squirrel monkeys (Saimiri spp.) and its correlation with the handling conditions

Avaliou-se a circulação de Campylobacter spp. em uma criação de primatas neotropicais macacos-de-cheiro (Saimiri spp.), clinicamente saudáveis, utilizados em investigações biomédicas. A análise foi feita no decorrer de sete anos não consecutivos, de 1995 a 1999, 2002 e 2003. Os resultados revelaram um maior índice de positividade no ano de 1996, em contraste com a ausência do agente em 2003. Os dados sugerem que as alterações realizadas no manejo animal, ao longo deste estudo, foram eficazes para a eliminação do Campylobacter spp. na criação de macacos-de-cheiro, levando os animais a uma melhor qualidade de vida e, consequentemente, obtendo-se um melhor produto para fins de pesquisas.The circulation of Campylobacter spp. in a breeding colony of clinically healthy neotropical primates squirrel monkeys (Saimiri spp.) used in biomedical investigation was evaluated. Analyses were undertaken during seven non-consecutive years: 1995 to 1999, 2002 and 2003. Results revealed a higher rate of positivity in 1996, in contrast to the absence of the agent in 2003. The data suggest that the changes made in the animal management during this study were effective for the Campylobacter spp. elimination of the squirrel monkeys breeding colony, leading to a better quality of life and, hence, resulting in a better animal for research

Características físicas, físico-químicas e sensoriais da água de frutos de coqueiro anão verde oriundo de produção convencional e orgânica Physical, physical-chemical and sensorial characteristics of coconut water from green-dwarfed coconut palm from conventional and organic production

Neste trabalho, objetivou-se comparar a qualidade da água de coco obtida de frutos de coqueiro anã verde, produzidos em dois sistemas distintos de produção: convencional e orgânico, mediante as análises físicas (cor da casca, peso, volume, comprimento e diâmetro), físico-químicas (sólidos totais, acidez titulável, pH, turbidez, açúcares solúveis totais e redutores) e os minerais: (Ca, Mg, Na, K, Fe, Mn, P, sulfato, cloreto e C.E.); e análise sensorial. Foram realizados os seguintes parâmetros sensoriais: avaliação global, turbidez, doçura e sabor. Os frutos utilizados nesse experimento encontravam-se com 210 dias após a polinização das inflorescências e foram provenientes de dois plantios comerciais do município de Trairí- Ceará. O experimento foi desenvolvido no laboratório de Fisiologia e Tecnologia de Pós-Colheita da Embrapa Agroindústria Tropical, Fortaleza-CE. Foi observado, a partir dos resultados das análises físicas, que o coco produzido em sistema convencional é melhor do que os produzidos organicamente. Para todas as variáveis estudadas, porém apenas as medições de comprimento e peso mostraram diferenças importantes por meio do teste Tukey em um nível de 5% de probabilidade. Nas análises físico-químicas e análise sensorial não houve diferença significativa para os tratamentos.<br>This work aimed to assess and compare the quality of coconut water produced in two different systems: standard and organic. The physical characteristics of the fruit were described (skin color, weight, water volume, length, and diameter), the physical-chemical characteristics of the water were assessed (total solid content, total titrable acidity, pH, turbidity, reducing and total soluble sugars), the mineral content was checked (Fe, P, K, Na, Ca, Mg, Mn, sulphate, chloride, and C.E.), and the sensory analysis was conducted assessing the following parameters: overall evaluation, turbidity, sweetness, and flavor. The fruits used in this experiment were harvested 210 days after the pollination of the flowers and were from two commercial plantations at the municipality of Trairí-Ceara.The experience was developed at the Physiology and Technology Post-Harvest Laboratory of Embrapa Tropical Agroindustry, Fortaleza-CE. We observed, from the results of the physical analysis, that the coconut produced in the standard system is better than that produced organically, for all of the studied variables. However, only the measurements of length and weight showed important differences through the Tukey test at the level of 5% probability. The physical-chemical and sensory analysis did not show significant differences between the treatments

Search for magnetically-induced signatures in the arrival directions of ultra-high-energy cosmic rays measured at the Pierre Auger Observatory

We search for signals of magnetically-induced effects in the arrival directions of ultra-high-energy cosmic rays detected at the Pierre Auger Observatory. We apply two different methods. One is a search for sets of events that show a correlation between their arrival direction and the inverse of their energy, which would be expected if they come from the same point-like source, they have the same electric charge and their deflection is relatively small and coherent. We refer to these sets of events as "multiplets". The second method, called "thrust", is a principal axis analysis aimed to detect the elongated patterns in a region of interest. We study the sensitivity of both methods using a benchmark simulation and we apply them to data in two different searches. The first search is done assuming as source candidates a list of nearby active galactic nuclei and starburst galaxies. The second is an all-sky blind search. We report the results and we find no statistically significant features. We discuss the compatibility of these results with the indications on the mass composition inferred from data of the Pierre Auger Observatory. © 2020 IOP Publishing Ltd and Sissa Medialab
