ABSTRACT
Abstract INTRODUCTION: Patients with Chagas disease (CD), caused by Trypanosoma cruzi, present a higher risk of developing other chronic diseases, which may contribute to CD severity. Since CD is underreported in the southern state of Paraná, Brazil, we aimed to characterize clinical and epidemiological aspects of individuals chronically infected with T. cruzi in Southern Brazil. METHODS: A community hospital-based study was performed, recording clinical/demographic characteristics of 237 patients with CD from Southern Brazil. To estimate the association between different forms of CD and sociodemographic and clinical variables, multiple logistic regression models were built using the Akaike information criterion. RESULTS: Mean age was 57.5 years and 59% were females. Most patients' (60%) place of origin/birth was within Paraná and they were admitted to the CD outpatient clinic after presenting with cardiac/digestive symptoms (64%). The predominant form of CD was cardiac (53%), followed by indeterminate (36%), and digestive (11%). The main electrocardiographic changes were in the right bundle branch block (39%) and left anterior fascicular block (32%). The average number of comorbidities per patient was 3.9±2.3; systemic arterial hypertension was most common (64%), followed by dyslipidemia (34%) and diabetes (19%); overlapping comorbidities were counted separately. Male sex was associated with symptomatic cardiac CD (OR=2.92; 95%CI: 1.05-8.12; p=0.040). CONCLUSIONS: This study provided greater understanding of the distribution and clinical profile of CD patients in Southern Brazil, indicating a high prevalence of comorbidities among these patients who are a vulnerable group due to advanced age and substantial risk of morbidity.

A Dislipidemia causa diversas doenças cardiovasculares e metabólicas, e as estatinas são seu tratamento padrão. Alternativas para o tratamento têm sido estudadas para reduzir efeitos colaterais. O flavonoide quercetina mostrou um potencial efeito antioxidante e redutor de colesterol. Objetivou-se analisar a diferença entre o tratamento atual com sinvastatina e outro com quercetina. 25ratos Wistar foram divididos em 5 grupos: G1 com dieta padrão; G2 recebendo dieta hiperlipídica (DH); G3 DH e 10mg/Kg de sinvastatina; G4 DH e 2mg/Kg de quercetina após 10 dias da dieta; G5 DH e 2mg/Kg de quercetina desde o início. Todos foram mantidos por 90 dias até eutanásia, quando coletou-se tecidos e sangue para análise.Encontrou-se uma maior proporção de diabetes (GLI>6Mmol/dl) no G2 quando comparado ao G3 e G5. Além da glicemia, G2 teve maiores valores de triglicerídeos e do índice TG-HDL, porém não apresentaram diferença significativa entre os demais
Dyslipidemia causes diverse cardiovascular and metabolic diseases, and statins are its standard treatment. Alternatives treatments to reduce side effects are in study. The flavonoid quercetin showed a potential antioxidant and cholesterol lowering effect. The aim was to analyze the difference between the current treatment with simvastatin and other with quercetin. 25 Wistar rats were divided into 5 groups: G1 with standard diet; G2 receiving hyperlipidic diet (HD); G3 HDand 10mg / kg simvastatin; G4 HD and 2 mg / kg quercetin after 10 days of diet; G5 HD and 2mg / kg quercetin from the beginning. All groups were kept for 90 days until euthanasia, when tissue and blood were collected for analysis. A higher proportion of diabetes (GLI>6Mmol / dl) was found in G2 compared to G3 and G5. In addition, G2 had higher levels of triglycerides and TG-HDL, but lack a significant difference between the others
ABSTRACT
O objetivo desse estudo foi comparar efeitos de dietas balanceadas e hiperlipídicas e avaliar a ação do azeite de oliva extra virgem (AO) na distribuição e na quantidade de gordura corporal. 27 ratos machos Wistar, por 90 dias, foram divididos em grupos submetidos a alimentações balanceadas e hiperlipídica, associadas ou não ao AO. Dados antropométricos, tecido adiposo branco (TAB) e tecido adiposo marrom (TAM) foram coletados e analisados estatisticamente. Os resultados mostraram que o consumo de dieta hiperlipídica provocou alterações significativas no peso corporal e no peso do TAB. A administração contínua de dieta balanceada com AO mostrou-se com um potencial efeito benéfico no combate à obesidade e à deposição de gordura branca no organismo, não demostrando alterações significativas no TAM.
The aim of this study was to compare effects of balanced diet and hyperlipidemic diet and evaluate the effects of extra virgin olive oil (EV) in the distribution and amount of body fat. 27 male Wistar rats during 90 days were divided into groups fed balanced diet and hyperlipidemic diet, associated or not with AO. Anthropometric data, white adipose tissue (WAT) and brown adipose tissue (BAT) were collected and analyzed statistically. The results showed that consumption of fat diet has caused significant changes in body weight and TAB weight. Continuous administration of balanced diet with EV showed up with a potential beneficial effect in combating obesity and deposition of white fat in the body, without demonstrating significant changes in TAM.
ABSTRACT
The aim of the present study was to detect natural infection by Leishmania (Leishmania) infantum in Lutzomyia longipalpis captured in Barcarena, state of Pará, Brazil, through the use of three primer sets. With this approach, it is unnecessary to previously dissect the sandfly specimens. DNA of 280 Lu. longipalpis female specimens were extracted from the whole insects. PCR primers for kinetoplast minicircle DNA (kDNA), the mini-exon gene and the small subunit ribosomal RNA (SSU-rRNA) gene of Leishmania were used, generating fragments of 400 bp, 780 bp and 603 bp, respectively. Infection by the parasite was found with the kDNA primer in 8.6% of the cases, with the mini-exon gene primer in 7.1% of the cases and with the SSU-rRNA gene primer in 5.3% of the cases. These data show the importance of polymerase chain reaction as a tool for investigating the molecular epidemiology of visceral leishmaniasis by estimating the risk of disease transmission in endemic areas, with the kDNA primer representing the most reliable marker for the parasite.

Para verificar a dinâmica da resistência aos antimicrobianos em uma propriedade rural no município de Santa Maria da Boa Vista, PE, foram avaliados 14 isolados de Staphylococcus epidermidis de caprinos com mastite subclínica. O perfil de resistência aos antimicrobianos foi determinado pelo teste de difusão em disco. A genotipificação foi realizada empregando o marcador REP (Repetitive Extragenic Palindromic) - PCR, utilizando o primer RW3A, enquanto os graus de similaridade e o fenograma de agrupamento foram estabelecidos por meio do coeficiente de Sorensen-Dice (SD) do algoritmo UPGMA, programa NTSYS-pc, o qual permitiu a identificação de 4 padrões dos 14 isolados de S. epidermidis, sendo oito no perfil A, quatro no perfil B, um no perfil C e um no perfil D. Para todos os grupos, a resistência à penicilina foi observada, enquanto que, para os grupos A e C, esta foi associada à lincomicina, no grupo B, esta foi associada à tetraciclina.
To verify the dynamics of antimicrobial resistance in a property in Santa Maria da Boa Vista city - Pernambuco were evaluated 14 Staphylococcus epidermidis isolates from goats with subclinical mastitis. The profile of antimicrobial resistance was determined by disk diffusion test. The genotyping was performed using the marker REP (Repetitive Extragenic Palindromic) - PCR, using RW3A primer, where the degrees of similarity and clustering phenogram were established by means of the Sorensen-Dice coefficient (SD) algorithm UPGMA, program NTSYS-pc, which allowed the identification of 4 patterns of 14 S. epidermidis isolates, being eight in the profile A, four in a profile B, one in profile C and one in profile D. For all groups to penicillin resistance was observed, while for groups A and C this was associated with lincomycin, for group B this was associated with tetracycline.
