Resumo Fundamento A estratificação ode risco é uma importante etapa na avaliação perioperatória. No entanto, os principais escores de risco não incorporam biomarcadores em seus conjuntos de variáveis. Objetivo Avaliar o poder incremental da troponina à estratificação de risco tradicional. Métodos Um total de 2230 pacientes admitidos na unidade de terapia intensiva após cirurgia não cardíaca foram classificados de acordo com três tipos de risco: Risco Cardiovascular (RCV), Índice de Risco Cardíaco Revisado (IRCR), e Risco Inerente da Cirurgia (RIC). O principal desfecho foi mortalidade por todas as causas. A regressão de Cox foi usada, assim como a estatística C antes e após a adição de troponina ultrassensível (pelo menos uma medida até três dias após a cirurgia). Finalmente, o índice de reclassificação líquida e a melhoria de discriminação integrada foram usadas para avaliar o poder incremental da troponina para a estratificação de risco. O nível de significância usado foi de 0,05. Resultados A idade média dos pacientes foi 63,8 anos e 55,6% eram do sexo feminino. A prevalência de lesão miocárdica após cirurgia não cardíaca (MINS) foi 9,4%. Pacientes com um RCV elevado apresentaram uma maior ocorrência de MINS (40,1% x 24,8%, p<0,001), bem como pacientes com alto RIC (21,3 x 13,9%, p=0,004) e aqueles com IRCR≥3 (3,0 x 0,7%, p=0,009). Pacientes sem MINS, independentemente do risco avaliado, apresentaram taxa de mortalidade similar. A adição de troponina à avaliação de risco melhorou a capacidade preditiva de mortalidade em 30 dias e de mortalidade em um ano em todas as avaliações de risco. Conclusão A prevalência de MINS é mais alta na população de alto risco. No entanto, sua prevalência na população de risco mais baixo não é desprezível e causa um maior risco de morte. A adição da troponina ultrassensível melhorou a capacidade preditiva da avaliação de risco em todos os grupos. perioperatória entanto variáveis tradicional 223 RCV, , (RCV) IRCR, IRCR (IRCR) RIC. .

Abstract Background Risk stratification is an important step in perioperative evaluation. However, the main risk scores do not incorporate biomarkers in their set of variables. Objective Evaluate the incremental power of troponin to the usual risk stratification Methods A total of 2,230 patients admitted to the intensive care unit after non-cardiac surgery were classified according to three types of risk: cardiovascular risk (CVR), Revised Cardiac Risk Index (RCRI); and inherent risk of surgery (IRS). The main outcome was all-cause mortality. Cox regression was used as well as c-statistics before and after addition of high-sensitivity troponin (at least one measurement up to three days after surgery). Finally, net reclassification index and integrated discrimination improvement were used to assess the incremental power of troponin for risk stratification. Significance level was set at 0.05. Results Mean age of patients was 63.8 years and 55.6% were women. The prevalence of myocardial injury after non-cardiac surgery (MINS) was 9.4%. High CVR-patients had a higher occurrence of MINS (40.1 x 24.8%, p<0.001), as well as high IRS-patients (21.3 x 13.9%, p=0.004) and those with a RCRI≥3 (3.0 x 0.7%, p=0.009). Patients without MINS, regardless of the assessed risk, had similar mortality rate. The addition of troponin to the risk assessment improved the predictive ability of death at 30 days and at 1 year in all risk assessments. Conclusion The prevalence of MINS is higher in the high-risk population. However, its prevalence in lower-risk population is not negligible and causes a higher risk of death. The addition of high-sensitivity troponin increased the predictive ability of risk assessment in all groups. evaluation However variables 2230 2 230 2,23 noncardiac non cardiac CVR, CVR , (CVR) RCRI (RCRI) IRS.

ABSTRACT Campomanesia adamantium (Cambess.) O. Berg (guavira) is a native plant of the Cerrado and Pantanal, which has several medicinal activities and fruits with a unique flavor rich in vitamin C. The species does not have defined cultivation methods, requiring studies to increase biomass production. An alternative is the use of organic residues that can influence the chemical, physical and biological characteristics of soils and consequently increase plant production. Thus, the objective was to evaluate the effect of different organic residues and bokashi, on the biomass production of plants and on the levels of phenols, flavonoids and antioxidant activity of tea from the leaves of guavira. Five substrates were studied in pots and protected environment: soil; soil + rice husk chicken manure; soil + sawdust chicken manure; soil + castor bean cake; soil + Organosuper® with or without the use of Bokashi in a 5x2 factorial scheme, in a randomized block experimental design. It was observed that the rice husk chicken manure can be used to increase the initial growth and biomass production of guavira keeping the leaves antioxidant activity tea stable. The use of bokashi benefits the growth of guavira only when no other organic residue is added to soil. Cambess. Cambess (Cambess.

Abstract The segment of isotonic beverages has been expanding its market, introducing new flavors and meeting the growing demand for new products. Cajuína, a drink for which Piaui holds a geographical indication certificate, was used in the development of a new sports drink. This work aimed to evaluate the shelf life of isotonic cajuína beverages conditioned at room temperature and under refrigeration, by analyzing the physicochemical, sensorial, and microbiological parameters. The analyzed samples had stable pH (< 3.0), titratable total acidity (0.18 g/100 mL), and °Brix (6.1 °Brix), and presented an acceptable soluble solids total/total titratable acidity (SST/ATT) ratio during storage. There was a vitamin C reduction of 83.3% and 75.27% from the initial amount in the beverage samples stored at room temperature and under refrigeration, respectively. Sensory analysis using the 9-point hedonic scale indicated good acceptance of the sports drink, and good buying intention. The sports drink also demonstrated high microbiological quality, with the absence of total coliforms, E. coli, molds, yeasts and Salmonella sp. The data from the stability study indicated that the isotonic cajuína drink retains its quality and safety, and can thus be consumed, for up to 150 days of storage.

Com o objetivo de contribuir para um melhor conhecimento do envolvimento das infecções pelos vírus das hepatites B e C, na etioepidemiologia do CHC na Amazônia Oriental, estudou-se 36 pacientes em Belém-PA. Foram avaliados marcadores sorológicos e a pesquisa do HBV-DNA e HCV-RNA pela reação em cadeia da polimerase. Observou-se etilismo em 33,3% e cirrose em 83,3%. Marcadores sorológicos das infecções pelo HBV e HCV foram encontrados respectivamente em 88,9% e 8,3%. O HBsAg foi encontrado em 58,3%; anti-HBc em 86%; anti-HBe em 85,7; HBeAg em 9,5%; anti-HBc IgM em 57,1%. O HBV-DNA foi detectado em 37,7% e em 65% dos HBsAg positivos; o HCV-RNA em 8,5% e em 100% dos anti-HCV positivos. AFP esteve alterada em 88,9% e acima de 400ng/ml em 75% dos casos. Conclui-se que a infecção pelo HBV parece ter importância na etiologia do CHC e ressalta-se a importância de implementar programas de vacinação e detecção precoce do tumor.

In order to contribute to a better understanding of the possible role of hepatits B and C in the etiopathogenis of HCC in the East Amazon, there were studied 36 patients in Belém/PA. Serological hepatitis markers were evaluated and polymerase chain reaction assays were used to detect HBV-DNA and HCV-RNA. Alcohol abuse was observed in 33.3% and cirrhosis in 83.3%. In 88.9% of the sample, one or more hepatitis B markers were positive. Also, 8.3% those patients had anti-HCV simultaneously positive. The HBsAg serological test was positive in 58.3%; anti-HBc in 86%; anti-HBe in 85.7%; anti-HBe in 9.5%; IgM anti-HBc in 57.1%. The HBV DNA was found in 37.7% and in 65% of the HBsAg positive. The HCV RNA was detected in 8.5% and in 100% of' the patients positive to anti-HCV. The AFP was above the normal value in 88.9% of patients, with levels up to 400ng/ml in 75% of them. In conclusion, hepatitis B virus infection seems to be important in the etiology of HCC and improving measures such immunization and screening in the risk population should be emphasyzed.

A infecção pelo virus da hepatite B apresenta amplo espectro de manifestações clínicas. Objetivando conhecer os genótipos do HBV mais prevalentes e determinar a ocorrência da mutação pré-core A-1896, em uma população da Amazônia oriental, correlacionando com o diagnóstico clínico, foram selecionados 51 pacientes portadores crônicos de HBsAg e HBV-DNA positivos e divididos em três grupos: grupo A (n=14, pacientes assintomáticos); grupo B (n=20, sintomáticos HBeAg positivos) e grupo C (n=17, sintomáticos HBeAg negativos), sendo usado o sequenciador automático ABI modelo 377 para identificação de genótipos e mutantes pré-core. Os resultados evidenciaram o genótipo A como o mais prevalente, 81,8%, 89,5% e 93,7%, nos grupos A, B e C, respectivamente. A mutação pré-core A-1896 foi encontrada em 11,5% (3/26), sendo todos assintomáticos. Concluiu-se que na população estudada o genótipo A foi o mais prevalente e houve baixa ocorrência do mutante pré-core A-1896, ambos não se constituindo fatores agravantes da doença hepática.

Hepatitis B virus (HBV) infection presents itself with a variety of clinical manifestations. The present work aims to describe the prevalence of HBV genotypes and the occurrence of precore mutation A-1896 in a population group of the Eastern Amazon region of Brazil and to correlate them with the clinical presentation of chronic HBV infection. 51 HBsAg carriers (HBV-DNA positive) were selected and divided into three groups: A (14 asymptomatic subjects), B (20 HBeAg positive symptomatic patients) and C (17 HBeAg negative symptomatic patients). Using an automa ed DNA sequencer ABI model 377 by sequencing for determined of genotypes and precore mutation. The results showed that the genotype A was the most commonly found (81,1%, 89,5% and 93,7% in groups A, B and C, respectively) and precore mutation A-1896 was described in 11,5% (3/26) of group A subjects. Genotype A of HBV was the most prevalent (89,1%) and low occurrence of precore mutation A-1896, both not associate with the worst outcome of the chronic infection of HBV.
