    O câncer é considerado um evidente problema de saúde pública, com causas primárias ainda não estão totalmente esclarecidas. Dentre os tipos de câncer existentes, o câncer de mama teve um aumento de sua incidência tanto no Brasil como em países subdesenvolvidos e desenvolvidos. Objetivou-se analisar o consumo alimentar e o estado nutricional, além da relação entre conhecimento nutricional e perfil antropométrico, de mulheres com câncer de mama em tratamento quimioterápico. A amostra contou com 14 mulheres maiores de 19 anos em tratamento quimioterápico no Centro Prudentino de Oncologia, da cidade de Presidente Prudente, SP. Os fatores de risco eram 7,14% menarca precoce; 7,14%, menopausa tardia; 42,85%, nuliparidade; 14,28% usavam terapia de reposição hormonal; 14,28% fumavam; 42,85% acima do peso e 28,57% sedentárias. O peso aumentou em 21,43% após o diagnóstico e 78,57% apresentaram moderado conhecimento nutricional, não correlacionando com o IMC (p=0,9). Destas, 64,3% estavam acima do peso; 71,43% apresentaram deficiente consumo de vitamina A, vitamina E (78,57%) e 71% possuíam consumo inadequado de fibras. Observou-se consumo de 24±9,6 kcal/kg/P e 0,7±0,4 g/kg de proteína. Conclui-se que o consumo alimentar está aquém de ser adequado e o excesso de peso ainda é prevalente nesse grupo de mulheres. Apesar de não ter havido correlação entre o conhecimento nutricional e o IMC, é importante incentivar estratégias de educação nutricional para adquirirem hábitos alimentares saudáveis, e prática regular de atividade física, a fim de evitar o desenvolvimento de doenças e a diminuição da qualidade de vida, além da recidiva do câncer de mama

    Get PDF
    Este trabalho teve como objetivo evidenciar e discutir se há alguma conduta mais adequada para a terapia nutricional enteral em pacientes em cuidados paliativos. Para responder a questão da pesquisa, foram selecionados descritores relacionados com os itens da estratégia PICO, sendo utilizados com os Descritores em Ciências da Saúde. A pesquisa foi embasada em oito artigos, todos publicados entre o ano de 2017 à 2021, encontrados nas seguintes bases de dados: PubMed, LILACS e Scielo. A maioria dos estudos provou que há uma grande incerteza de como agir na alimentação do paciente em cuidados paliativos e até onde ir com esse paciente. Sendo assim, o nutricionista é indispensável nesse momento, definindo a melhor conduta nutricional juntamente com a equipe multidisciplinar. Portanto a TNE deve ser individualizada, visando o conforto e a qualidade de vida em primeiro lugar

    Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

    This study evaluated the effect of probiotics supplementation with or without Zinc (Zn), added to the mineral mixture, in humoral immune response in sheep vaccinated with a single dose of rabies vaccines. Forty-five malecrossbred rams Santa Inês, aged 6 months were randomly divided into 3 groups (15 animals / group): Control group (CG) received 10 grams of mineral / animal / day, the probiotics group (GP) received 10 grams of mineral added 4 grams of probiotics / animal / day and Probiotics and Zinc group (GPZn) received 10 grams of mineral added 4 grams of probiotics and 14.4 mg of zinc sulfate per animal per day added to the probiotics. The individual titles of neutralizing antibodies were determined using the technique of neutralization-based Rapid Fluorescent Focus Inhibition Test (RFFIT) and Fluorescent Inhibition Microtest (FIMT). There were no statistically significant differences between the mean serum concentrations between groups. It was concluded that the probiotics administration with or without zinc did not improve the immune humoral response of antibody rabies

    To evaluate the effect of a probiotic on the aggressiveness of a chemically induced colorectal tumor in rats. Twenty-five male Fisher 344 rats, 250 g, provided with feed and water ad libitum, were randomly divided into 5 groups (5 rats/group): GControl, no treatment; GTumor, tumor induction; GTumor+5FU, tumor induction, 5-Fluorouracil applied; GTumor+Prob, induction of the tumor, supplemented with probiotic; GTumor+5-FU+Prob, tumor induction, 5-Fluorouracil applied, supplemented with probiotic. For tumor induction 20 mg/kg of 1,2-dimethylhydrazine was applied intraperitoneally over 4 weeks, followed by an interval of 15 days, and then repeated for a further 4 weeks. Five weeks after the final dose of the carcinogen, treatment was initiated with 5-Fluorouracil (15 mg/kg, intraperitoneally/week) and a commercial probiotic (1 × 109 CFU, daily/gavage). Data were analyzed by One Way Variance Analysis and means compared by Dunnett's test. GraphPad Prism statistical software was used. The histopathological analyzes were evaluated by the chi-square test. A 5% type-I error was considered statistically significant. Compared with the GTumor, the GTumor+Prob (p < 0.0373) and GTumor+5-FU+Prob (p < 0.0003) demonstrated an attenuated effect on the aggressiveness of the colorectal tumor, with a reduction in the count of Aberrant Crypt foci; and a lower percentage of malignant neoplastic lesions in the GTumor+Prob (40% low grade tubular adenoma, 40% carcinoma in situ, 20% low grade adenocarcinoma) and GTumor+5-FU+Prob (40% low grade tubular adenoma and 60% carcinoma in situ). Probiotic supplementation has the potential to decrease the formation of aberrant crypts and ameliorate tumor malignancy, enhancing the antitumor effect of 5-Fluorouracil chemotherapy in colic segments237The authors would like to thank the NANOBIOSS/UNICAMP Laboratories, INOMAT/UNICAMP, the NANOREG-MCTIC Program, and the Surgery Science Program/UNICAMP and University of Western São Paulo for financial support and research viabilit
