Gastric disorders of cattle in western Rio Grande do Sul State, Brazil / Distúrbios gástricos de bovinos no Oeste do Rio Grande do Sul

A retrospective study of gastric disorders in autopsied cattle in the Western region of Rio Grande do Sul State, was performed. The exam reports of bovine necropsy of the Veterinary Pathology Laboratory, Unipampa, were analyzed in the period from 2010 to 2018. All cases in which death was primarily caused by disturbance in the gastric chambers were included. During the period evaluated, 141 cattle were necropsied. Of those, 25 had gastric disorders. Of those, 53% had alterations in the rumen, followed by abomasum (17%), involvement of two chambers (13%) and reticulum (9%). Most cases corresponded to beef cattle raised in an extensive system and most them for calf production and fattening with an average age of approximately three years. The cases occurred in farms of four different municipalities. Bullous bloat by excessive Trifolium repens ingestion was the gastric disturbance with the highest number of dead cattle observed in this study, especially in irrigated áreas of livestock farms. Cases such as lactic acidosis, ruminal alkalosis due to excessive urea ingestion and Baccharis coridifolia poisoning were also important gastric disturbances in necropsied cattle, associated especially with poor management and period of scarcity of good quality fodder. Cases of Clostridium perfringens infection were also observed in young cattle suggesting that it is an important infectious agent in the evaluated cattle herds, also showing failures in vaccination of the herds. As observed, gastric disturbances in cattle in the western region of Rio Grande do Sul have several causes. Metabolic/toxic and infectious disturbances were important causes of mortality in the herds, inducing considerable economic losses. Based on this study, it is clear that the majority of outbreaks or isolated cases occurred due to errors in the management of the properties and the vast majority of them could have been avoided with improvements in the technical qualification of the workers and simple adjustments in the farming methods. It is also emphasized the importance of the conclusive diagnosis to control these disorders, once after the orientation to the producers, was observed significant decrease in cattle losses in the farms.(AU)

Foi realizado estudo retrospectivo dos distúrbios gástricos em bovinos necropsiados na região Oeste do Rio Grande do Sul. Foram analisados os relatórios de exame de necropsia de bovinos do Laboratório de Patologia Veterinária (LPV) da Universidade Federal do Pampa (Unipampa), Rio Grande do Sul, no período de 2010 a 2018. Foram incluídos todos os casos nos quais a morte foi causada primariamente pelo distúrbio nas câmaras gástricas. De um total de 141 bovinos necropsiados, 25 corresponderam a distúrbios gástricos. Dentre esses, 53% apresentaram alterações no rúmen, seguido de abomaso 17%, acometimento concomitante de duas câmaras 13% e retículo 9%. A maioria dos casos ocorreram em bovinos de corte criados em sistema extensivo e a maioria destinados à produção de bezerros e engorda com média de idade de aproximadamente três anos. Os casos ocorreram em propriedades rurais de quatro municípios da região Oeste do estado. O timpanismo bolhoso por ingestão excessiva de Trifolium repens foi o distúrbio gástrico com maior número de bovinos mortos observados nesse estudo, especialmente em propriedades com criação de animais em áreas de irrigação. Casos como acidose láctica, alcalose ruminal por intoxicação por ureia e intoxicação por Baccharis coridifolia também foram importantes distúrbios gástricos nos bovinos necropsiados e percebeu-se sua associação a falhas no manejo e à época de escassez de forragem de boa qualidade. Foram observados ainda casos de infecção por Clostridium perfringens em bovinos jovens o que sugere também tratar-se de um importante agente infeccioso nos rebanhos bovinos avaliados, demonstrando ainda falhas na vacinação dos rebanhos. Conforme observado, diversos são os distúrbios gástricos em bovinos na região Oeste do Rio Grande do Sul, tendo como importantes causas de mortalidades os distúrbios metabólicos/tóxicos e infecciosos, induzindo consideráveis perdas econômicas. Com base nesse levantamento, percebe-se que a maioria dos surtos ou casos isolados estudados ocorreram por erros no manejo nas propriedades e, na sua grande maioria, poderiam ter sido evitados com especialização da mão de obra e ajustes simples. Ressalta-se ainda a importância do diagnóstico conclusivo para controle desses distúrbios, uma vez que, após a orientação aos produtores, observou-se significativa diminuição das perdas de bovinos nas propriedades.(AU)

Interleukin 8 (-251 T>A) polymorphism in children and teenagers infected with Helicobacter pylori

Abstract Background Helicobacter pylori (H. pylori) is a gram-negative bacterium that colonizes the human stomach and causes a variety of gastric diseases. This study evaluated the correlations between the -251 (T>A) (rs4073) polymorphism of interleukin-8 (IL-8), the etiology of gastric disease, and H. pylori infection in pediatric and adolescent patients. Methods DNA samples were obtained from 285 gastric biopsies from pediatric patients. H. pylori was detected by PCR, whereas PCR-RFLP was used to characterize the -251 (T>A) polymorphism of IL-8. Results The histological analysis revealed the presence of gastritis in 158 patients (55.44%). H. pylori was found in 71 samples (24.9%). The -251 (T>A) polymorphism revealed that 58 (29.47%) samples were TT, 143 (50.18%) samples were TA, and 84 (20.35%) samples were AA. Conclusions Our findings suggest that IL8-251 A allele may be an important risk factor for the development of gastric disease when associated with H. pylori infection.

Immune function of red blood cells in chronic gastritis and duodenal ulcer disease / 中国综合临床

Objective To explore changes of the immune function of red blood cells in gastric disease.Methods RBC C3b receptor rosette(RBCC3bRR)and RBC immune complex rosette(RBCICR)were tested in chronic gastritis group(n =103),duodenal ball ulcer group(n =75)and control group(n =30)to evaluate the immune function of RBC.Results RBCC3bRR were(20.83 ± 5.16)％ in the control group,(16.26 ±5.17)％ in the chronic gastritis group and(13.65 ± 5.19)％ in the duodenal ball ulcer group.RBCICR were respectively(7.63 ± 4.09)％,(10.59 + 4.45)％ and(10.04 ± 4.13)％ in these three groups.RBCC3bRR of chronic gastritis and duodenal ball ulcer were lower than control group(P ＜0.0l),while RBCICR were higher than normal control group(P ＜0.05 and P ＜0.01 respectively).There was no significant difference on RBCC3bRR and RBCICR between HP negative chronic gastritis and HP negative duodenal ball ulcer and between HP positive chronic gastritis and HP positive duodenal ball ulcer(P ＞ 0.05).RBCC3bRR of HP positive chronic gastritis and duodenal ball ulcer was significantly lower than that of HP negative(P ＜ 0.05and P ＜ 0.01 respectively),RBCICR significantly higher than that of HP negative(P ＜ 0.01).After HP eradication,RBCC3bRR of patients with chronic gastritis and duodenal ball ulcer was increased significantly (P＜0.05 and P ＜ 0.01 respectively).RBCICR was significantly lower than before treatment(P ＜ 0.01).Conclusion HP infection,chronic gastritis and duodenal ulcer can decrease the immune function of red blood cells.

A Structural Model Based on Pender's Model for Quality of Life of Chronic Gastric Disease / 간호학회지

This study was designed to construct a structural model for quality of life of chronic gastric disease. The hypothetical model was developed based on the literature review and Pender's health promotion model. Data were collected by questionnaires from 459 patients with chronic gastric disease in a General Hospital from July 1999 to August 2000 in Seoul. Data analysis was done with SAS 6.12 for descriptive statistics and PC-LISREL 8.13 Program for Covariance structural analysis. The results are as follows : 1. The fit of the hypothetical model to the data was moderate, thus it was modified by excluding 1 path and including free parameters and 2 path to it. The modified model with path showed a good fitness to the empirical data (Chi2=934.87, p<.0001, GFI=0.88, AGFI=0.83, NNFI=0.86, RMSR =0.02, RMSEA=0.07). 2. The perceived barrier, health promoting behavior, self-efficacy, and self-esteem were found to have significant direct effects on the quality of life. 3. The health concept, health perception, emotional state, and social support were found to have indirect effects on quality of life of chronic gastric disease. In conclusion, the derived model in this study is considered appropriate in explaining and predicting quality of life of chronic gastric disease. Therefore it can effectively be used as a reference model for further studies and suggested direction in nursing practice.
