Distribution of cases of congenital heart disease in a hospital in Oeste Paulista / Distribuição dos casos de cardiopatias congênitas em um hospital do Oeste Paulista

The aim of this research was to conduct a comprehensive spatial-temporal analysis of the population affected by congenital heart anomalies assisted at the Pediatric Cardiology Outpatient Department at the distinguished Western Paulista reference hospital. We conducted a retrospective study involving the analysis of electronic database records and patient medical charts for individuals diagnosed with congenital heart disease during the period from July 2013 to July 2018. A total of 298 medical records were selected for the analysis of variables encompassing the ICD-10 codes, gender, spatial distribution, and temporal trends. It was possible to observe that septal defects were the most prevalent congenital heart abnormalities, and there was no gender-based difference. An increase in diagnoses was noted from 2014, coinciding with the implementation of the "heart test," and 51% of the cases were from Presidente Prudente, with a higher concentration of cases in the industrial park area. There is an association between cardiac congenital malformations and an adverse environmental context. The findings can inform public health policies aimed at reducing the exposure of the most vulnerable population in pursuit of improving health indicators (AU).

O objetivo deste trabalho foi analisar a distribuição espaço-temporal dos pacientes com cardiopatias congênitas aten-didos no Ambulatório de Cardiologia Pediátrica do Hospital de referência do Oeste Paulista. Realizamos um estudo retrospectivo com análise de dados de base eletrônica e prontuários dos pacientes diagnosticados com cardiopatia congênita entre os períodos de julho de 2013 a julho de 2018. Foram selecionados 298 prontuários para análise das variáveis de CID-10, gênero, distribuição espacial e série temporal. Foi possível observar que os defeitos septais foram as cardiopatias mais prevalentes, não houve diferença entre os gêneros. Notou-se aumento do diagnóstico a partir de 2014, com implementação do teste do coraçãozinho e 51% dos casos eram da cidade de Presidente Prudente, com maior concentração de casos na região do parque industrial. Há uma relação na incidência das malformações cardíacas com o meio ambiente desfavorável. Os resultados encontrados podem guiar políticas de saúde pública, visando reduzir a exposição da população mais vulnerável, na busca da melhora nos índices de saúde (AU).

Antibacterial activity of barbatimão (Stryphnodendron adstringens) against periodontopathogens and cytotoxic effects on fibroblasts.

This in vitro study aimed to evaluate the growth-inhibitory effects against periodontal disease-causing bacteria and cytotoxic effects against mouse fibroblast cells of the Stryphnodendron adstringens (barbatimão) hydroalcoholic extract. The contents of phenols and tannins in the extract were determined. The growth-inhibitory activity of the barbatimão was evaluated by determining the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). The viability of fibroblast cells was analyzed using the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide assay at 24 and 48 h post-treatment. The MIC values of the extract against Prevotella intermedia, Porphyromonas gingivalis, and Fusobacterium nucleatum were 0.05, 0.125, and 2 mg mL-1, respectively, while the MBC values were 4, 2, and 2 mg mL-1, respectively. The viability rate of barbatimão (0.25 mg mL-1)-treated L929 cells was higher than that of chlorhexidine (0.12%)-treated L929 cells at 48 h post-treatment. The contents of total phenolics and total tannins in the extract were 837.39 ± 0.10 and 785.82 ± 0.14 mg of tannic acid equivalent per gram of the extract, respectively. These findings indicate that the barbatimão hydroalcoholic extract, which exerted potent growth-inhibitory effects against the test microbial species and low cytotoxic effects on fibroblasts, has potential applications in the development of novel mouthwash products.

Cooking processes increase bioactive compounds in organic and conventional green beans.

The influence of cooking methods on chlorophyl, carotenoids, polyamines, polyphenols contents and antioxidant capacity were analyzed in organic and conventional green beans. The initial raw material had a higher content of chlorophyl and total phenolics in conventional green beans, whereas organic cultive favored flavonoid content and antioxidant capacity. Polyamines and carotenoids were similar for the two crop systems. After the cooking process, carotenoids (ß-carotene, lutein and zeaxanthin) increased. Microwave heating favored the enhancement of some polar compounds, whereas pressure cooking favored carotenoids. When we used the estimation of the radical scavenging activity by electron spin resonance (ESR) spectroscopy, a reduction of the DPPH radical signal in the presence of green bean extracts was observed, regardless of the mode of cultivation. The highest reduction of the ESR signal ocurred for microwave cooking in organic and conventional green beans, indicating a higher availability of antioxidants with this type of heat treatment.

Caracterização da polpa de pêssegos produzidos em São Manuel-SP / Characterization of peach fleshes produced in São Manuel, State of São Paulo

Os benefícios do consumo de frutas e hortaliças sempre foram associados à presença de vitaminas e fibras. Entretanto, outros compostos são importantes e muitos exercem função antioxidante, destacando-se os polifenóis e pigmentos. Neste trabalho, foram caracterizadas as polpas de sete cultivares de pêssegos, duas de polpa branca e cinco de polpa amarela, utilizando-se frutas no ponto de consumo (frutos com coloração de fundo amarela). Foi avaliada a concentração de vitamina C, polifenóis, pigmentos e a capacidade antioxidante. O delineamento experimental utilizado foi o inteiramente casualizado, constando de sete tratamentos e três repetições, sendo cada repetição composta por seis frutos. O teor de vitamina C variou de 7,74 a 17,31mg em 100g-1 de polpa; a concentração de polifenóis variou de 53,33 a 141,77mg de ácido gálico em 100g-1 de polpa; o conteúdo de clorofila 'A' variou de 11,59 a 44,61ug em 100g-1 de polpa; o conteúdo de clorofila 'B' variou de 69,69 a 411,37ug em 100g-1 de polpa; os carotenóides totais variaram de 28,69 a 81,58ug em 100g-1 de polpa; as antocianinas variaram de 85,13 a 336,05ug em 100g-1 de polpa. A atividade antioxidante variou de 35,81 a 65,39mg de DPPH reduzido 100g-1 de polpa. Foi verificada correlação positiva significativa entre vitamina C e atividade antioxidante.

The benefits of fruit and vegetable consumption have been always associated with the presence of vitamins and fiber. However, other compounds are important and many exert antioxidant function, especially the polyphenols and pigments. In this study, fleshes of seven peach cultivars were characterized, two from white flesh cultivars and five of yellow flesh, all from fruits at the point of consumption (fruits with yellow background color). It was evaluated the concentration of vitamin C, polyphenols, pigments and antioxidant capacity. The experimental design was completely randomized, consisting of seven treatments and three replications, with six fruits per plot. The vitamin C content ranged from 7.74 to 17.31mg of vitamin C 100g-1 flesh, the concentration of polyphenols ranged from 53.33 to 141.77mg of gallic acid 100g1 flesh, the chlorophyll 'A' content ranged from 11.59 to 44.61ug chlorophyll 'A' 100g-1 flesh, the chlorophyll 'B' content ranged from 69.69 to 411.37ug chlorophyll 'B' 100g-1 flesh; carotenoids ranged from 28.69 to 81.58ug-1 carotenoids 100g flesh; anthocyanins ranged from 85.13 to 336.05ug-1 antocyanins 100g flesh. The antioxidant activity ranged from 35.81 to 65.39mg of reduced DPPH- 100g-1 flesh. Significant positive correlation was found between vitamin C and antioxidant activity.

Qualidade microbiológica da melancia minimamente processada com diferentes métodos de sanitização / Microbiological quality of minimally processed watermelon with different methods of sanitization

Este trabalho teve como objetivo verificar o efeito da sanitização com cloro antes e após o corte da melancia minimamente processada e da irradiação na sua qualidade microbiológica. Após a colheita os frutos foram transportados para o Laboratório de Frutas e Hortaliças da FCA/UNESP, onde foram limpos, selecionados e classificados de acordo com a sua maturação e sanidade.(...) Ao final do período de armazenamento verificou-se que os produtos vegetais sanitizados antes do corte, o tratamento com a dose de 500ppm apresentaram a menor contagem microbiana, porém os produtos com as doses de 300 e 400ppm se conservaram por 8,0 e 8,3 dias respectivamente. Para os produtos vegetais sanitizados após o corte, verificou-se que os do tratamento com 200ppm, apresentaram a menor carga microbiana, o tratamento com a dose de 50ppm os produtos vegetais se conservaram por 8,8 dias. Os produtos vegetais irradiados com as doses de 0,4 e 0,5 kGy apresentaram a menor contaminação microbiana e se conservaram por 9,7 e 8,5 dias respectivamente. Logo, pode-se concluir que a irradiação na dose de 0,4 kGy foi o tratamento mais indicado para a melancia minimamente processada.
