RESUMO: O Sapajus libidinosus é um primata do novo mundo pertencente à família Cebidae que habita os biomas da caatinga e cerrado do Brasil. Atualmente esta classificado como quase ameaçado pelos principais orgãos de proteção animal. O conhecimento da bioquímica sérica, proteína C reativa e proteinograma são importantes na preservação desta espécie. O nosso estudo tem como objetivo determinar os intervalos de referência para várias variáveis bioquímicas e proteinograma. Para isso, foram colhidas amostras de sangue de 50 macacos da espécie S. libidinosus (25 machos e 25 fêmeas) mantidos em cativeiro no estado da Paraíba, Brasil. A análise descritiva e os cálculos dos intervalos de referência foram estimados segundo as diretrizes da Sociedade Americana de Patologia Clínica Veterinária com o uso do software Reference Value Advisor 2.1. Na população total (n=50), considerando o factor idade, foram observadas diferenças significativas (P < 0,05) para a creatinina e proteínas totais (valores superiores nos adultos) e para a albumina e bilirrubina indirecta (valores superiores nos jovens). Foram encontradas diferenças associadas ao sexo (fêmeas versus machos, P < 0,05) para a ureia e creatinina séricas (valores superiores nos machos) e albumina e Beta-Globulinas (valores superiores nas fêmeas). Conclui-se que, tanto quanto é do conhecimento dos autores, os resultados deste estudo são inovadores e podem ser utilizados como intervalos de referência para avaliação do estado de higidez dos animais e é pioneiro na determinação da proteína C reativa nesta espécie. É importante salientar que o sexo e a faixa etária podem ter influência e devem ser levados em consideração pelos profissionais na interpretação dos exames.

ABSTRACT: Sapajus libidinosus is a New World primate belonging to the Cebidae family that lives in the caatinga and cerrado, which are known Brazilian biomes. It is currently classified as near threatened, almost endangered, by the main animal protection organizations. Knowledge of biochemistry, the C-reactive protein, and the proteinogram are important for the preservation of this species. Our study established reference intervals for several biochemical variables and the proteinogram. For this purpose, blood samples were collected from 50 S. libidinosus monkeys (25 males and 25 females) kept in captivity at the Brazilian state of Paraíba. Descriptive analysis and reference intervals were estimated following the guidelines of the American Society of Veterinary Clinical Pathology, using the Reference Value Advisor 2.1 software. In the overall population (n=50), significant differences (P < 0.05) were noted for creatinine and total proteins when considering the age factor (higher in adults), as well as for albumin and indirect bilirubin (higher in juveniles). Sex-associated differences (females versus males, P < 0.05) were reported for serum urea and creatinine (higher in males), as well as for albumin and Beta-Globulins (higher in females). In conclusion, to the authors’ best knowledge, the present results are innovative and can be used as reference intervals for assessing the animals’ health status. Moreover, it is also pioneer in determining the C-reactive protein in this species. It is important to emphasize that gender and age categories can have an influence and should be considered when interpreting the tests results.

Abstract Background Human Papillomavirus (HPV) is the main etiological factor for the development of cervical cancer. HPV 18 is the second most frequent type, accounting for up to 65% of all cases. HPV intratypic variation may influence the potential for progression to invasive cancer. The aim of this study was to evaluate the prevalence of human papillomavirus 18 intratypic variants in cervical cancer samples from women in the state of Maranhão, Brazil. Methods The study included 118 women over 18 years of age with a diagnosis of cervical cancer. Tumor fragments were collected and subjected to DNA extraction and Polymerase Chain Reaction (PCR) for HPV detection using the PGMY09/11 and GP+5/6 primers. Positive samples were submitted to automated sequencing for viral genotyping. To determine the HPV 18 lineages, positive samples were submitted to PCR, using specific primers to amplify the LCR and E6 regions of HPV 18 virus. Results HPV was present in 88 women (73.3%). Of those, 48 (54%) were HPV 16, the most prevalent, followed by 12 (13.6%) HPV 18. Histologically, squamous cell carcinoma was predominant (79.1%). Among the HPV 18 variants identified, 10 (80%) belonged to lineage A, and sublineages A1, A2, A3, and A4. Two (29%) HPV 18 B variant was also detected, with the sublineages B1 and B2. In this study, the C variant was not found. There was no statistically significant association between the HPV 18 lineages found and sociodemographic and lifestyle variables (p > 0.05). Conclusions A higher frequency of HPV 16 and 18 were found in women with cervical cancer in the state of Maranhão, Brazil, with a high prevalence of the lineage A among women with HPV 18.

Abstract: En | Text: En | PDF: En

ABSTRACT Immune exhaustion and senescence are scarcely studied in HIV-pediatric patients. We studied the circulatory CD8 T cells activation/exhaustion and senescent phenotype of children and adolescents vertically infected with HIV or uninfected controls based on the expression of human leukocyte antigen (HLA-DR), CD38, T cell immunoglobulin and immunoreceptor tyrosine-based inhibitory motif (ITIM) domain (TIGIT), programmed death 1 (PD-1) and CD57 by flow cytometry, during approximately one year. Eleven HIV-infected (HI) and nine HIV-uninfected (HU) children/adolescents who received two doses or one dose of meningococcal C conjugate vaccine (MenC), respectively, were involved in this study. Blood samples were collected before the immunization (T0), 1–2 months after the first dose (T1), and 1–2 months after the second dose (T2), which was administered approximately one year after the first one. HI patients not receiving combined antiretroviral therapy (cART) showed a higher frequency of CD8 T cells TIGIT+, PD-1+ or CD57+, as well as a higher frequency of CD8 T cells co-expressing CD38/HLA-DR/TIGIT or CD38/HLA-DR/PD-1 when compared to HI treated or HU individuals, at all times that they were assessed. CD8 T cells co-expressing CD38/DR/TIGIT were inversely correlated with the CD4/CD8 ratio but positively associated with viral load. The co-expression of CD38/DR/TIGIT or CD38/DR/PD-1 on CD8 T cells was also inversely associated with the CD4 T cells expressing co-stimulatory molecules CD127/CD28. The results showed a higher expression of exhaustion/senescence markers on CD8 T cells of untreated HI children/adolescents and its correlations with viral load.

BACKGROUND A positive Trypanosoma cruzi polymerase chain reaction (PCR) is associated with a worse prognosis in patients with chronic Chagas disease (CD). OBJECTIVES To study the association of clinical, electrocardiographic, and echocardiographic characteristics and biomarker blood levels with positive T. cruzi PCR in chronic CD. METHODS This is a single-centre observational cross-sectional study. Positive T. cruzi PCR association with clinical, electrocardiographic, and echocardiographic characteristics, and biomarker blood levels were studied by logistic regression analysis. p values < 0.05 were considered significant. FINDINGS Among 333 patients with chronic CD (56.4% men; 62 ± 10 years), T. cruzi PCR was positive in 41.1%. Stepwise multivariate logistic regression showed an independent association between positive T. cruzi PCR and diabetes mellitus {odds ratio (OR) 0.53 [95% confidence interval (CI) 0.30-0.93]; p = 0.03}, right bundle branch block [OR 1.78 (95% CI 1.09-2.89); p = 0.02], and history of trypanocidal treatment [OR 0.13 (95% CI 0.04-0.38); p = 0.0002]. Among patients with a history of trypanocidal treatment (n = 39), only four (10%) patients had a positive T. cruzi PCR. MAIN CONCLUSIONS Among several studied parameters, only diabetes mellitus, right bundle branch block, and history of trypanocidal treatment showed an independent association with positive T. cruzi PCR. History of trypanocidal treatment was a strong protective factor against a positive T. cruzi PCR.

Abstract Background: Recent studies suggest that follow-up paracentesis (FuP) in cases of spontaneous bacterial peritonitis (SBP) should only be performed if there is a clinical and/or analytic worsening. We aimed to evaluate which patients with SBP would benefit from the FuP. Métodos: This retrospective study included consecutive patients diagnosed with SBP between January 2011 and June 2018 in our tertiary center. Clinical and analytical data were obtained at baseline and on the third day of antibiotic therapy. An adequate response on the third day of treatment was defined by a decrease of ≥25% in the neutrophil count of the ascitic fluid (AF). Results: Ninety-six episodes of PBE in 75 patients (79% male sex, mean age 61 ± 11 years old) were included. At admission, a higher serum neutrophil count (p = 0.043), a lower level of serum total proteins (p = 0.040), a positive culture in AF (p < 0.001) and a previous diagnosis of diabetes mellitus (p = 0.035) were related to inadequate response (IR). At day 3, acute kidney injury (p = 0.023), C-reactive protein >100 mg/L (p < 0.001), the presence of fever (p = 0.047) and abdominal pain (p < 0.001) were also associated with IR. In multivariate analysis, the presence of respiratory insufficiency (OR = 16.403; 95% CI: 2.315-116.222; p = 0.005) and abdominal pain (OR = 10.381; 95% CI: 1.807-59.626; p = 0.009) at admission, serum white blood cell count >9 × 109 (OR = 5.832; 95% CI: 1.275-26.669; p = 0.023), and CRP >100 mg/L (OR = 5.043; 95% CI: 1.267-20.076; p = 0.022) at day 3 of antibiotic therapy were predictors of IR. The predictive model presented good accuracy [AUROC of 0.893 (p < 0.001)] - a cutoff of 0.090 had a sensitivity, specificity, positive predictive value, and negative predictive value for IR of 97, 46, 83, and 77%, respectively. Conclusions: The performance of FuP on day 3 after the beginning of empiric therapy should be individualized, according to clinical and analytic variables of this predictive model.

Resumo Introdução: Estudos recentes têm sugerido a realização de paracentese de seguimento ao 3º dia, na peritonite bacteriana espontânea (PBE), apenas em doentes com agravamento clínico e/ou analítico. Este trabalho pretende avaliar quais os doentes em que a paracenteses ao 3º dia se mantém essencial. Methods: Estudo retrospetivo realizado em centro terciário, com inclusão dos doentes com PBE entre janeiro de 2011 e junho de 2018. Dados clínicos e analíticos foram obtidos à data de admissão e ao 3° dia de antibioterapia. A resposta terapêutica foi considerada adequada quando a contagem de neutrófilos no líquido ascítico era ≥25%. Resultados: Foram incluídos 96 episódios de PBE correspondentes a 75 doentes (79% homens, com idade media de 61 ± 11 anos). À admissão, a presença de diabetes mellitus (p = 0.035), uma maior contagem de neurófilos séricos (p = 0.043), nível inferior de proteínas séricas totais (p = 0.040) e positividade nas culturas de líquido ascítico total (p < 0.001) relacionaram-se com inadequada resposta (IR). Ao 3° dia de antibioterapia, a presença de lesão renal aguda (p = 0.023), proteína C reativa >100 mg/L (p < 0.001), febre (p = 0.047) e dor abdominal (p < 0.001) foram também associados a IR. Na análise multivariada, a presença de insuficiência respiratória (OR = 16.403; 95% CI: 2.315-116.222; p = 0.005) e dor abdominal (OR = 10.381; 95% CI: 1.807-59.626; p = 0.009) à admissão, contagem séria de leucócitos >9 ×109 (OR = 5.832; 95% CI: 1.275-26.669; p = 0.023) e PCR >100 mg/L (OR = 5.043; 95% CI: 1.267-20.076; p = 0.022) ao 3° dia de antibioterapia foram preditores de IR. O modelo preditivo apresentado apresenta boa acuidade [AUROC de 0.893 (p < 0.001)] - para um cutoff de 0.090 tem uma sensibilidade, especificidade, valor preditivo positivo e valor preditivo negativo para IR de 97, 46, 83, e 77%, respetivamente. Conclusões: De acordo com o nosso modelo, a realização de paracenteses de seguimento ao 3 dia após início de antibioterapia empírica deverá ser individualizada, de segundo as variáveis clínicas e analíticas apresentadas.

ABSTRACT Objective: To analyze and compare COVID-19 patient characteristics, clinical management and outcomes between the peak and plateau periods of the first pandemic wave in Portugal. Methods: This was a multicentric ambispective cohort study including consecutive severe COVID-19 patients between March and August 2020 from 16 Portuguese intensive care units. The peak and plateau periods, respectively, weeks 10 - 16 and 17 - 34, were defined. Results: Five hundred forty-one adult patients with a median age of 65 [57 - 74] years, mostly male (71.2%), were included. There were no significant differences in median age (p = 0.3), Simplified Acute Physiology Score II (40 versus 39; p = 0.8), partial arterial oxygen pressure/fraction of inspired oxygen ratio (139 versus 136; p = 0.6), antibiotic therapy (57% versus 64%; p = 0.2) at admission, or 28-day mortality (24.4% versus 22.8%; p = 0.7) between the peak and plateau periods. During the peak period, patients had fewer comorbidities (1 [0 - 3] versus 2 [0 - 5]; p = 0.002) and presented a higher use of vasopressors (47% versus 36%; p < 0.001) and invasive mechanical ventilation (58.1 versus 49.2%; p < 0.001) at admission, prone positioning (45% versus 36%; p = 0.04), and hydroxychloroquine (59% versus 10%; p < 0.001) and lopinavir/ritonavir (41% versus 10%; p < 0.001) prescriptions. However, a greater use of high-flow nasal cannulas (5% versus 16%, p < 0.001) on admission, remdesivir (0.3% versus 15%; p < 0.001) and corticosteroid (29% versus 52%, p < 0.001) therapy, and a shorter ICU length of stay (12 days versus 8, p < 0.001) were observed during the plateau. Conclusion: There were significant changes in patient comorbidities, intensive care unit therapies and length of stay between the peak and plateau periods of the first COVID-19 wave.

RESUMO Objetivo: Analisar e comparar as características de pacientes críticos com a COVID-19, a abordagem clínica e os resultados entre os períodos de pico e de platô na primeira onda pandêmica em Portugal. Métodos: Este foi um estudo de coorte multicêntrico ambispectivo, que incluiu pacientes consecutivos com a forma grave da COVID-19 entre março e agosto de 2020 de 16 unidades de terapia intensiva portuguesas. Definiram-se as semanas 10 - 16 e 17 - 34 como os períodos de pico e platô. Resultados: Incluíram-se 541 pacientes adultos com mediana de idade de 65 [57 - 74] anos, a maioria do sexo masculino (71,2%). Não houve diferenças significativas na mediana de idade (p = 0,3), no Simplified Acute Physiology Score II (40 versus 39; p = 0,8), na pressão parcial de oxigênio/fração inspirada de oxigênio (139 versus 136; p = 0,6), na terapia com antibióticos na admissão (57% versus 64%; p = 0,2) ou na mortalidade aos 28 dias (24,4% versus 22,8%; p = 0,7) entre o período de pico e platô. Durante o período de pico, os pacientes tiveram menos comorbidades (1 [0 - 3] versus 2 [0 - 5]; p = 0,002); fizeram mais uso de vasopressores (47% versus 36%; p < 0,001) e ventilação mecânica invasiva na admissão (58,1% versus 49,2%; p < 0,001), e tiveram mais prescrição de hidroxicloroquina (59% versus 10%; p < 0,001), lopinavir/ritonavir (41% versus 10%; p < 0,001) e posição prona (45% versus 36%; p = 0,04). Entretanto, durante o platô, observou-se maior uso de cânulas nasais de alto fluxo (5% versus 16%; p < 0,001) na admissão, remdesivir (0,3% versus 15%; p < 0,001) e corticosteroides (29% versus 52%; p < 0,001), além de menor tempo de internação na unidade de terapia intensiva (12 versus 8 dias; p < 0,001). Conclusão: Houve mudanças significativas nas comorbidades dos pacientes, nos tratamentos da unidade de terapia intensiva e no tempo de internação entre os períodos de pico e platô na primeira onda da COVID-19.

ABSTRACT This work aimed to evaluate the efficacy of fungicides for controlling anthracnose (Colletotrichum gloeosporioides) on peach palm (Bactris gasipaesvar.gasipaes) seedlings in nursery beds and in newly planted peach palms in the field. The nursery experiment included two fungicide combinations: [thiophanate-methyl + chlorothalonil (TM + C) and pyraclostrobin + epoxiconazole (P + E)], three application intervals (7, 14, and 21 days), and an additional nontreated control. The two field experiments with newly planted peach palms tested the fungicide combinations TM + C at 15-day intervals for 12 months after transplanting, comparing to the control without fungicide application. The severity of anthracnose was assessed, and it was used for calculating the area under the disease progress curve (AUDPC). The fungicides TM + C and E + P applied at 7-days intervals were effective in the control of anthracnose in peach palm seedlings, resulting in the lowest severities and AUDPC. The fungicide TM + C reduced the maximum disease severity and AUDPC under field conditions. However, differences in the final severity of anthracnose and stem diameter were not significant compared to the control. Therefore, the use of fungicides for control of anthracnose in the field is not necessary.

RESUMO Contexto: Carcinoma hepatocelular (CHC) é o tipo mais comum de câncer de fígado. Os fatores de risco para CHC incluem infecção pelo vírus da hepatite C (VHC) e B (VHB), cirrose alcoólica e alterações genéticas que podem afetar diversas vias celulares. Objetivo: Este estudo teve como objetivo analisar a expressão gênica e proteica sérica de VEGF, AFP, CSTB, β-catenina e GPC3 em grupos com CHC, cirrose ou VHC e controles, e sua relação com o estadiamento clínico nos grupos CHC e cirrose, bem como sua valores de sensibilidade e especificidade. Métodos: Duzentos e trinta indivíduos foram distribuídos no Grupo 1 (G1) - 80 pacientes com CHC; Grupo 2 (G2) - 76 pacientes com cirrose de qualquer etiologia; Grupo 3 (G3) - 33 pacientes com VHC; Grupo 4 (G4 - Controles) - 41 indivíduos sem sinais clínicos ou bioquímicos de qualquer doença hepática. A expressão gênica foi analisada por qRT-PCR e as proteínas séricas foram realizadas pelo método ELISA. Resultados: Aumento da expressão de VEGF e AFP pode ser observado em pacientes BCLC estágio D em comparação com pacientes estágio B, e pacientes estágio C apresentaram maior expressão de CTNNB1, em comparação com pacientes estágio B (P<0,05). Para VEGF e GPC3, foi observado poder discriminatório entre pacientes com CHC e controles (AUC = 0,71; 0,82, respectivamente). O CSTB mostrou poder discriminatório na comparação entre pacientes com VHC e controles (AUC =0,74). Conclusão: O presente estudo confirma a sensibilidade do CSTB sérico no diagnóstico da hepatite C, e a expressão gênica de VEGF e GPC3 sérica conferem sensibilidade e especificidade para o diagnóstico de CHC.

ABSTRACT Background: Hepatocellular carcinoma (HCC) is the most common type of liver cancer. Risk factors for HCC include hepatitis C (HCV) and B (HBV) virus infection, alcoholic cirrhosis and genetic alterations that can affect several cellular pathways. Objective: This study purposed to analyze the gene and serum protein expression of vascular endothelial growth factor (VEGF), angiogenesis, alpha fetoprotein, cystatin B (CSTB), β-catenin and glypican-3 (GPC3) in groups with HCC, cirrhosis or HCV and controls, and their relation with clinical staging in the HCC and cirrhosis groups, as well its sensitivity and specificity values. Methods: A total of 230 individuals were distributed in Group 1 (G1) - 80 patients with HCC; Group 2 (G2) - 76 patients with cirrhosis due to any etiology; Group 3 (G3) - 33 patients with HCV; Group 4 (G4 - controls) - 41 individuals without clinical or biochemical signs of any liver disease. Gene expression was analyzed by qRT-PCR and serum proteins were performed using the ELISA method. Results: Increased VEGF and angiogenesis, alpha fetoprotein expression could be observed in BCLC stage-D patients compared to stage-B patients, and stage-C patients showed higher expression of β-catenin, compared to stage-B patients (P<0.05). For VEGF and GPC3, discriminatory power was observed between HCC patients and controls (AUC =0.71; 0.82, respectively). CSTB showed discriminatory power in the comparison between patients with HCV and controls (AUC =0.74). Conclusion The present study confirms the sensitivity of serum CSTB in the diagnosis of hepatitis C, and gene expression of VEGF and serum GPC3, confer both sensitivity and specificity for the diagnosis of HCC.

Resumo Esta revisão integrativa propôs-se a analisar na literatura da área estudos sobre fatores associados à adesão ao tratamento da hepatite C. Foram pesquisados artigos, publicados em inglês, espanhol e português, nas bases de dados Lilacs, Medline, PsycINFO, Web of Science, Scopus e CINAHL, entre os anos 2000 a 2019. Foram obtidas, inicialmente, 540 publicações e, posteriormente, aplicando-se os critérios de inclusão estabelecidos, foram selecionados 22 artigos. Constatou-se nos artigos analisados que a porcentagem de não adesão ao tratamento variou de 12% a 32%. Foram identificados como facilitadores da adesão: receber tratamento para transtornos psiquiátricos identificados durante o tratamento, ter conhecimento sobre os medicamentos e doença, receber tratamento menos complexo e com maior possibilidade de cura, apresentar menor número de eventos adversos, ter apoio social e bom vínculo com o médico. Foram identificadas como barreiras à adesão: presença de sintomas depressivos e de outros transtornos mentais, uso abusivo de álcool e substâncias psicoativas, baixa escolaridade, idade (ser mais jovem); etnia (afro-americanos), desemprego, não ter parceiro fixo, relatar estigma, distância do serviço de saúde, complexidade e eventos adversos do tratamento. Foram também identificadas lacunas nas pesquisas sobre adesão.

Abstract This integrative review examined factors associated with hepatitis C treatment adherence. The articles included were published in English, Spanish and Portuguese in the Lilacs, Medline, PsycINFO, Web of Science, Scopus and CINAHL databases, between 2000 and 2019. Initially, 540 publications were found and, after applying the study inclusion criteria, 22 articles were selected. Percentage non-adherence to treatment ranged from 12% to 32%. The variables identified as facilitating adherence were: receiving treatment for psychiatric disorders identified during treatment; knowing about medications and disease; receiving less complex treatment with greater likelihood of cure; fewer adverse events; social support; doctor-patient communication; and/or being in relationships. Barriers to adherence identified were: presence of depressive symptoms and other mental disorders; abuse of alcohol and psychoactive substances; education; age; ethnicity; unemployment; not having a steady partner; stigma; distance from health services; and the complexity and adverse effects of treatment. This review identified gaps in research on adherence.

Abstract: En | Text: En | PDF: En

Furanaphthoquinones are well known in medicinal chemistry for exhibiting relevant structural heterogeneity and bioactivities. In this work, it was synthesized a series of furanaphthoquinones through a tandem reaction between lawsone (8) and cyclic ketones in the presence of morpholine. This strategy provides an efficient and general method for synthesizing furanaphthoquinones with activity against the epimastigote form of Trypanosoma cruzi (T. cruzi), the parasite that causes Chagas disease. Compound 9b was the better prototype, and it exhibited high potency for causing parasite death, showed reduced acute toxicity towards mammalian cells, and was capable of rupturing the epimastigote plasma membrane and acting on sterol 14α-demethylase (CYP51). Additionally, 9b reduced trypomastigote viability by 99% after 24 h. Candidate 9b demonstrated the best and most promising profile when bound to CYP51.

RESUMO Contexto O transplante renal é o tratamento de escolha para pacientes com doença renal terminal e está associado a menor mortalidade quando comparado aos métodos dialíticos. O Brasil é o país com o segundo maior número de transplantes renais do mundo e, entre esses pacientes, observa-se que as alterações hepáticas são comuns. A frequência das alterações hepáticas varia de 20 a 50% pós-transplante e tem importante impacto na sobrevida e qualidade de vida desses pacientes. Existem poucos dados sobre a frequência, causas e características dessas alterações. Objetivo Determinar a prevalência das diferentes causas de anormalidades hepáticas em receptores de transplante renal, associar as características dessas anormalidades a variáveis demográficas, epidemiológicas e clínicas, comparar as características das alterações hepáticas entre diferentes etiologias e avaliar possíveis alterações no diagnóstico em dois períodos diferentes de tempo. Métodos Estudo epidemiológico descritivo, transversal, observacional, realizado no ambulatório “Hepato-Rim” do Hospital São Paulo (EPM/UNIFESP), centro de atendimento especializado a pacientes com anormalidades hepáticas e doenças renais de base. Resultados Quinhentos e oitenta e um pacientes transplantados foram avaliados. As etiologias mais prevalentes de anormalidades hepáticas foram hepatite C e B, sobrecarga de ferro, doença hepática gordurosa não alcoólica e lesão hepática induzida por drogas. A causa mais comum — hepatite C — foi analisada em maiores detalhes. Em comparação com as outras causas, essa infecção foi a mais frequente em pacientes mais velhos, pacientes do sexo feminino e pacientes com mais tempo de transplante e hemodiálise. A análise dos dois períodos mostrou que os pacientes do período 1 (P1 — 1993 a 2005) eram mais velhos e encaminhados com maior frequência devido à sorologia positiva; encaminhamento devido a anormalidades de aminotransferases predominou durante o período 2 (P2 — 2006 a 2018). Os diagnósticos predominantes foram hepatite C e B durante P1 e doença hepática gordurosa não alcoólica e lesão hepática induzida por drogas durante P2. Conclusão A avaliação das principais alterações hepáticas em receptores de transplante renal é importante, pois permite melhor manejo desses pacientes na investigação diagnóstica e no tratamento e contribui para a prevenção de complicações nesta população especial.

ABSTRACT Background Kidney transplant is the treatment of choice for patients with end-stage renal disease and is associated with lower mortality when compared to dialysis methods. Brazil is the country with the second largest number of kidney transplants in the world and among these patients it has been observed that liver abnormalities are common. The frequency of liver abnormalities ranges from 20-50% post-transplantation, and have an important impact on the survival and quality of life of these patients. There are scarce data about the frequency, causes and characteristics of these alterations. Objective To determine the prevalence of the different causes of hepatic abnormalities in kidney transplant recipients, to associate the characteristics of these abnormalities with demographic, epidemiological and clinical variables, to compare the characteristics of hepatic alterations between different etiologies, and to evaluate possible changes in diagnosis over two different periods of time. Methods Descriptive, cross-sectional observational, epidemiological study was conducted at the outpatient “Hepato-Rim”clinic of Hospital São Paulo (EPM/UNIFESP), a center providing specialized care for patients with hepatic abnormalities and underlying kidney diseases. Results Five-hundred eighty-one transplant patients were evaluated. The most prevalent etiologies of liver abnormalities were hepatitis C and B, iron overload, nonalcoholic fatty liver disease (NAFLD), and drug-induced liver injury (DILI). The most common cause — hepatitis C — was analyzed in greater detail. Compared to the other causes, this infection was more frequent in older patients, female patients, and patients with a longer time since transplantation and hemodialysis. Analysis of the two periods showed that patients of period 1 (P1 — 1993 to 2005) were older and were more frequently referred because of positive serology; referral due to aminotransferases abnormalities predominated during period 2 (P2 — 2006 to 2018). The predominant diagnoses were hepatitis C and B during P1 and NAFLD and DILI during P2. Conclusion Assessment of the main hepatic alterations in kidney transplant recipients is important because it permits better management of these patients in terms of diagnostic investigation and treatment and contributes to the prevention of complications in this special population.

RESUMO: Objetivou-se com este estudo verificar a eficiência do 1,4-dimetilnaftaleno na supressão da brotação e a consequente manutenção da qualidade de tubérculos de batata das cultivares Asterix e Challenger, em diferentes temperaturas e tempos de armazenamento. Foram testados seis tratamentos, com e sem 1,4-DNM, nas temperaturas de 8 °C e 20 °C. As avaliações foram feitas aos 0, 45, 90, 135 e 180 dias após a aplicação. Os parâmetros avaliados foram: número de brotos, teores de açúcares solúveis totais, teores de açúcares redutores, e não redutores, e coloração dos palitos de batata após a fritura. Os efeitos do 1,4-DMN no controle da qualidade das batatas resultaram no controle da brotação e em menores teores de açúcares solúveis totais e de açúcares redutores, sobretudo na cultivar Challenger e à temperatura de 20 ºC.

ABSTRACT: The aim of this study was to verify the efficiency of 1,4-dimethylnapthalene in suppressing sprouting and the consequent maintenance of the quality of potato tubers of Asterix and Challenger cultivars, at different temperatures and storage regimes. Six treatments were tested, with and without 1.4-DNM, at temperatures of 8 ° C and 20 ° C. Assessments were made at 0, 45, 90, 135 and 180 days after application. The parameters evaluated were: number of sprouts, levels of total soluble sugars, levels of reducing and non-reducing sugars and coloration of potato strips after frying. The effects of 1.4-DMN on the quality control of potatoes resulted in sprout control and lower levels of total soluble sugars and reducing sugars, especially in the Challenger cultivar and at a temperature of 20 ºC.

Abstract The banana is one of the most consumed fruits in the world, but it has little shelf life due to its high water activity. Drying is able to increase shelf life and pre-treatments can optimize the process. The objective was to study the solar drying kinetics and evaluate the effect of pre-treatments on the drying kinetics and physico-chemical quality of 'Prata' bananas. The drying was carried out in a solar dryer and the pre-treatments consisted of immersing the samples in solutions of water, citric acid (1%) and lemon juice (10%). Water loss, drying kinetics, mathematical models and physical-chemical and colorimetric characteristics of fresh and dried bananas were evaluated. The drying rate was higher at the beginning and stabilized after 20 hours. The mathematical model of Midilli and Kucuk was the one that best fit the experimental data. The water content, ascorbic acid and the parameters L *, b *, C * and h ° reduced after drying. Reducing sugars and a * coordinate increased and the acidity was not changed with drying. The solar drying of 'Prata' bananas is a sustainable and economical way to make a product available with a longer shelf life.
