Estudos sorológicos e parasitologies na Amebíase e em outras infecções parasitárias intestinais em Recife e áreas circunvizinhas, nordeste do Brasil

Parasitological examinations were carried out during April to August, 1987, with 187 out-patients of the IMIP hospital, located in the center of Recife City, and 464 inhabitants of several villages around Cabo City, 50 Km southeast of Recife, Pernambuco, Brazil. Approximately 71% of the IMIP patients and 92% of the Cabo inhabitants were infected with at least one species of intestinal parasite. There was minimum difference in the prevalence rate of Trichuris trichiura between two areas, whereas the prevalence rates of Ascaris lumbricoides, hookworms, Strongyloides stercoralis, Schistosoma mansoni and Entamoeba histolytica were higher in the inhabitants of the Cabo City area. Only Giardia lamblia was more prevalent in the out-patients of IMIP hospital. Test tube cultivation revealed that the prevalence rate of Necator americanus in both areas was much higher than that of Ancylostoma duodenale , and also that the prevalence rate of S. stercoralis of the IMIP patients and Cabo inhabitants were 4.5% and 9.6%, respectively. Six hundred and fifteen sera were serologically examined for amoebiasis by the gel diffusion precipitation test (GDP) and enzyme linked immunosorbent assay (ELISA) using the antigen prepared from axenically cultured trophozoite of E. histolytica (strain HM-ITMSS). No positive reaction was observed in all of the sera as examined by GDP, while 32 out of 615 sera were positive on ELISA.Exames parasitológies foram realizados em 187 pacientes do Hospital do IMIP e 464 habitantes de vários vilarejos no município do Cabo, 50 Km à sudeste de Recife, durante os meses de abril a agosto. Aproximadamente 71% dos pacientes examinados do IMIP e 92% dos examinados do Cabo apresentavam-se infectados com, no mínimo, uma espécie de parasita intestinal. Houve uma diferença mínima na taxa de prevalência de Trichuris trichiura entre as duas áreas, entretanto a prevalência de Ascaris lumbricoides, família Ancylostomidae, Strongyloides stercoralis, Schistosoma mansoni e Entamoeba histolytica foi maior entre os habitantes do Cabo. Somente a Giardia lamblia apresentou uma taxa de prevalência maior nos pacientes do IMIP. O cultivo em tubo de ensaio revelou que a prevalência do Necator americanus em relação a do Ancylostoma duodenale era muito maior em ambas as áreas e que a do S. stercoralis entre os pacientes do IMIP e dos habitantes do Cabo era, respectivamente, 4.5% e 9.6%. A amebíase foi verificada através de exames sorológicos, imunodifusão em gel (GDP) e enzima imunoensaio (ELISA), usando como antígeno extrato bruto preparado a partir dos trofozoitos de E. histolytica (cepa HM-1: IMSS), realizados em 615 soros, onde nenhuma reação positiva aparente foi observada através da imunodifusão, contudo foram observados resultados positivos em 32 dos 615 casos através da enzima imunoensaio

Genealogies. Identitats tèxtils

Del 28 de gener al 25 de març de 2018. Espai Zero, Centre de Documentació i Museu Tèxtil de TerrassaLa present mostra està formada per un conjunt d’obres que parteixen de la matèria tèxtil per fer arribar visions plurals sobre les relacions de gènere a la nostra societat, desenvolupades dins de la Facultat de Belles Arts de la Universitat de Barcelona. Aquest tèxtil, que es confereix a l’entrellaçar fils independents, s’ubica en l’àmbit domèstic i l’engendra un sector femení durant molts segles; només des d’algunes dècades ençà s’inclou com a matèria partícip i reivindicada en l´art. Aquest canvi es produeix críticament amb la flongesa d’una roba que no encaixa amb els materials rígids ni amb els cànons tradicionals que aquest art havia establert fins aleshores; la seva aparició en una sala expositiva qüestiona, així, les bases dels seus estàndards històrics. Sense exaltar la seducció pel material, el punt de partida de la proposta es centra en el tèxtil com a recurs per posar en comú enfocaments antagònics sobre les necessitats de reconèixer identitats que es troben als marges d´un camí social comú; per treure a la llum aquestes presències implícites, o bé per esquerdar les jer arquies ja assentades sobre el gènere o la sexualitat. En totes les seves possibilitats apareixerà, el tèxtil, ajustat o amorf, fràgil o robust, tensat o tan alliberat com ho són els plantejaments conceptuals i artístics amb els quals s’enfilen les obres d’aquesta exposició

Parasitological and serological studies on Amoebiasis and other intestinal parasitic infections in Recife and its suburban area, northeast Brazil

Parasitological examinations were carried out during April to August, 1987, with 187 out-patients of the IMIP hospital, located in the center of Recife City, and 464 inhabitants of several villages around Cabo City, 50 Km southeast of Recife, Pernambuco, Brazil.

Effects of once-weekly exenatide on cardiovascular outcomes in type 2 diabetes

BACKGROUND: The cardiovascular effects of adding once-weekly treatment with exenatide to usual care in patients with type 2 diabetes are unknown. METHODS: We randomly assigned patients with type 2 diabetes, with or without previous cardiovascular disease, to receive subcutaneous injections of extended-release exenatide at a dose of 2 mg or matching placebo once weekly. The primary composite outcome was the first occurrence of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke. The coprimary hypotheses were that exenatide, administered once weekly, would be noninferior to placebo with respect to safety and superior to placebo with respect to efficacy. RESULTS: In all, 14,752 patients (of whom 10,782 [73.1%] had previous cardiovascular disease) were followed for a median of 3.2 years (interquartile range, 2.2 to 4.4). A primary composite outcome event occurred in 839 of 7356 patients (11.4%; 3.7 events per 100 person-years) in the exenatide group and in 905 of 7396 patients (12.2%; 4.0 events per 100 person-years) in the placebo group (hazard ratio, 0.91; 95% confidence interval [CI], 0.83 to 1.00), with the intention-to-treat analysis indicating that exenatide, administered once weekly, was noninferior to placebo with respect to safety (P<0.001 for noninferiority) but was not superior to placebo with respect to efficacy (P=0.06 for superiority). The rates of death from cardiovascular causes, fatal or nonfatal myocardial infarction, fatal or nonfatal stroke, hospitalization for heart failure, and hospitalization for acute coronary syndrome, and the incidence of acute pancreatitis, pancreatic cancer, medullary thyroid carcinoma, and serious adverse events did not differ significantly between the two groups. CONCLUSIONS: Among patients with type 2 diabetes with or without previous cardiovascular disease, the incidence of major adverse cardiovascular events did not differ significantly between patients who received exenatide and those who received placebo
