ABSTRACT

Resumo Estudo transversal avaliou a associação entre deficiência de zinco sérico e declínio cognitivo em 591 idosos da comunidade residentes nos municípios de Campinas, Limeira e Piracicaba-SP. A cognição foi avaliada pelo Instrumento de Triagem de Habilidades Cognitivas-CASI-S considerando declínio pontuação <23 em idosos de 60-69 anos e <20 em idosos ≥70 anos. Considerou-se deficiência de zinco sérico valor de <70 µg/dL para mulheres e 74 µg/dL para homens. Entre os domínios cognitivos, idosos com deficiência de zinco tiveram pontuação média significativamente menor no teste de memória (p=0,018). A prevalência da deficiência de zinco foi de 3,9%, e de 9,4% de declínio cognitivo, sendo significativamente maior em idosos com deficiência de zinco do que os que não tinham (26,1% e 8,8%, respectivamente). Em análise de regressão logística múltipla ajustada, os fatores que permaneceram associados ao declínio cognitivo foram deficiência de zinco (OR=3,80; IC95%=1,30-11,12), baixa escolaridade (OR=3,12; IC95%=1,49-6,50), não ter companheiro (OR=1,88; IC95%=1,04-3,42), risco de desnutrição (OR=3,98; IC95%=2,36-6,71), e histórico de acidente vascular encefálico (OR=2,70; IC95%=1,04-6,98). A deficiência de zinco foi associada ao declínio cognitivo em idosos. Ações na atenção básica de saúde são necessárias para prevenir a deficiência deste nutriente.


Abstract This is a cross-sectional study evaluating the association between zinc deficiency and cognitive decline in 591 community-dwelling older adults living in the cities of Campinas, Limeira, and Piracicaba-SP. Cognitive status was evaluated using the Cognitive Abilities Screening Instrument-CASI-S, considering a decline for scores <23 for those aged 60-69 and <20 for those aged ≥70 years. Among the evaluated cognitive domains, older adults with zinc deficiency had significantly lower mean scores on the memory test (p=0.018). For zinc deficiency, values below 70 µg/dL were considered for women and 74 µg/dL for men. The prevalence of zinc deficiency was 3.9%, and cognitive deficit was 9.4%, being significantly higher in those with zinc deficiency compared with those with normal serum zinc concentrations. In adjusted multiple logistic regression analysis, the factors that remained associated with cognitive decline were zinc deficiency (OR=3.80; 95%CI=1.30-11.12), low schooling level (OR=3.12; 95%CI=1.49-6.50), lack of a partner (OR=1.88; 95%CI=1.04-3.42), risk of malnutrition (OR=3.98; 95%CI=2.36-6.71), and a history of encephalic vascular accident (OR=2.70; 95%CI=1.04-6.98). Zinc deficiency was associated with the presence of cognitive decline in older adults. Actions in primary health care are necessary to prevent the deficiency of this nutrient.

ABSTRACT

Abstract AIMS The aims of this study were to investigate and characterize the anthropometric, nutritional, genetic, psychological and sleep variables of slalom kayakers, and to verify the correlation of these variables with the slalom kayakers' performance. METHODS Ten elite Brazilian team slalom kayakers participated of this study. Nutritional analysis was made by the Food Record (three days), 24 Hour Dietary Recall and Food Frequency Questionnaire. The ACE I/D, AGTMet235Thr, ACTN3R577X and BDKRB2+9/-9 were genotyped for genetic profile. The Profile of Mood States (POMS) and Sports Competition Anxiety Test (SCAT) were applied to investigate the psychological variables. The Pittsburgh Sleep Quality Index (PSQI), Epworth Sleep Scale (ESS) and Morningness-eveningness questionnaire (MEQ) were used for sleep traits analysis. Performance trials were performed on a white-water course with 24 gates, and finish time was considered as the variable related to performance. RESULTS Significant correlations were obtained between Performance Time Trial and %Fat (r=0.77), Energy (r=-0.75), Protein (r=-0.76), Carbohydrate (r=-0.72), Vitamin B6 (r=-0.87), Vitamin A (r=-0.82), Thiamine (r=-0.77), Riboflavin (r=-0.71), Magnesium (r=-0.86) and Phosphorus (r=-0.74) intake, besides the Fatigue mood domain (r=0.73) and the SCAT score (r=0.67). Athletes genotyped with the I, T, R and +9 alelle also presented better performances. CONCLUSIONSIn summary, the novel results provided by this study reinforce the necessity of considering several aspects during athlete development in order to achieve better performance in competitions.

ABSTRACT

BACKGROUND: Recently, mesenteric fat has been proposed to play a role in the pathophysiology of Crohn's disease (CD), as fat hypertrophy is detected close to the affected intestinal area; however, there are few studies regarding autophagy and creeping fat tissue in CD. OBJECTIVE: Evaluate autophagy-related proteins and proinflammatory cytokines in intestinal mucosa and mesenteric fat in patients with CD and controls. PATIENTS AND METHODS: Ten patients with CD, eight with non-inflammatory disease who underwent surgery, and eight with normal ileocolonoscopy were studied. The expression of LC3-II, TNF-alpha and IL-23 was determined by immunoblot of protein extracts. In addition, total RNA of LC3 and Atg16-L1 were determined using RT-PCR. RESULTS: The expression of LC3-II was significantly lower in the mesenteric tissue of CD when compared to controls (p < 0.05). In contrast, the intestinal mucosa of the CD group had higher levels of LC3-II (p < 0.05). However, mRNA expression of autophagy-related proteins was similar when compared to mesenteric fat groups. TNF-alpha and IL-23 expressions were higher in intestinal mucosa of CD than in control (p < 0.05). CONCLUSION: These findings suggest a defect in the autophagic activity of the creeping fat tissue in CD, which could be involved with the maintenance of the inflammatory process in the intestinal mucosa.

INTRODUÇÃO: Recentemente, tem se proposto que o tecido mesenterial possa participar da fisiopatologia da DC, uma vez que é notória a hipertrofia da gordura mesenterial próxima ao segmento intestinal afetado pela doença. Entretanto, há poucos estudos relacionando autofagia e tecido mesenterial na DC. OBJETIVO: Avaliar autofagia e citocinas na mucosa intestinal e no mesentério de pacientes com DC. PACIENTES E MÉTODOS: Dez pacientes com DC, oito sem doença inflamatória intestinal que foram submetidos à cirurgia, e oito com ileocolonoscopia normal, foram estudados. As expressões de LC3-II, TNF-alfa e IL-23 foram determinadas por imunoblot de extrato protéico total. Além disso, expressão gênica de LC3 e de Atg16-L1 foi realizada por RT-PCR. RESULTADOS: A expressão de LC3-II foi significativamente menor no tecido mesenterial de pacientes com DC quando comparada à dos controles (p < 0,05); as amostras de tecido intestinal do grupo DC apresentaram maior expressão de LC3-II (p < 0,05). Entretanto, as expressões gênicas relacionadas à autofagia foram similares nos grupos de tecido mesenterial. Os níveis de TNF-alfa e de IL-23 foram maiores na mucosa intestinal do grupo CD (p < 0,05). CONCLUSÃO: Estes achados sugerem alteração da autofagia no mesentério na DC, o que pode estar envolvido com a manutenção da inflamação na mucosa intestinal. (AU)

ABSTRACT

A inflamação inespecífica do reservatório ileal (RI) após retocolectomia total é a complicação pós-operatória mais comum nos doentes operados por retocolite ulcerativa inespecífica (RCUI). Os mecanismos imunológicos envolvidos na etiologia não são totalmente conhecidos. OBJETIVO: Avaliar a ativação de STAT-1 e a expressão da citocina INF-gama em mucosa de RI endoscópica e histologicamente normal, de doentes operados por RCUI e PAF, assintomáticos. CASUISTICA E MÉTODOS: Estudou-se 18 doentes submetidos à retocolectomia total com RI em (J), sendo nove com RCUI e nove com polipose adenomatosa familiar (PAF). Realizou-se biópsias da mucosa dos RI e de íleo terminal. As expressões de INF-gama e a ativação de STAT-1 foram avaliadas por meio de imunoblot de extrato protéico total. RESULTADOS: A ativação de STAT-1 foi maior em mucosa de RI de doentes operados por RCUI, quando comparada aos grupos PAF e Controle (p menor que 0.05). A expressão de INF-gama foi maior no grupo RCUI quando comparada ao grupo Controle (p menor que 0.05), mas não em relação ao grupo PAF (p maior que 0.05). CONCLUSÃO: Estes achados podem justificar a maior susceptibilidade dos doentes com RCUI à inflamação inespecífica do RI quando comparados aos portadores de PAF, sendo a principal via inflamatória similar à verificada na RCUI.


Pouchitis after total retocolectomy is the most common complication in ulcerative colitis (UC). The immunological mechanisms involved in the genesis of pouchitis are unclear. PURPOSE: To evaluate STAT-1 activation and IFN-gama expression in normal ileal pouch mucosa. METHODS: Eighteen asymptomatic patients submitted to total retocolectomy and J pouch, were evaluated, being nine with UC and nine with FAP. The activation of STAT-1 and expressions of the cytokine were determined by immunoblot of total protein extracts from pouch mucosal biopsies. RESULTS: STAT-1 activation was increased in UC, when compared to FAP and controls. Higher levels of IFN-gama expression were observed in UC when compared to control group, but was similar to FAP. CONCLUSIONS: These findings could explain a higher susceptibility to this inflammatory complication in UC when compared to FAP, which may be similar to UC disease.

ABSTRACT

A ileíte do reservatório pós retocolectomia total constitui uma das complicações mais comuns nos doentes com RCUI, apresentando pequena freqüência nos doentes com PAF. OBJETIVO: Avaliar a atividade inflamatória em mucosa de reservatórios ileais endoscopicamente normais, através da expressão de TNF-alfa, NF-kapaB e IL-1beta. CASUíSTICA E MÉTODOS: Selecionaram-se 20 doentes submetidos à retocolectomia total com reservatório ileal em "J" pelo Grupo de Coloproctologia da UNICAMP, sendo 10 doentes com RCUI e 10 com PAF. O grupo controle foi constituído por íleo terminal de intestino normal. Realizadas biópsias da mucosa do reservatório ileal e do íleo terminal normal, e congeladas em nitrogênio líquido. A expressão de TNF-alfa e IL-1beta foi analisada por extrato total e de NF-kB por meio de imunoprecipitado. A separação protéica foi feita por eletroforese em gel de poliacrilamida. RESULTADOS: Expressão de TNF-alfa e IL-1beta apresentaram níveis maiores nos doentes com RCUI, quando comparados àqueles com PAF (p<0.05). Por outro lado, a expressão de NF-kapaB foi maior nos doentes com RCUI, porém sem diferença estatística em relação aos de PAF. O grupo controle apresentou pequena expressão de TNF-alfa (p<0.01) e expressão de NF-kapaB (p>0.1) e IL-1beta (p > 0.05) sem diferença estatística em relação aos demais grupos. CONCLUSÃO: Os doentes com RCUI apresentaram maiores níveis de expressão das citocinas estudadas, mesmo sem evidência clínica e endoscópica de ileíte do reservatório, podendo justificar maior suscetibilidade dos doentes com RCUI a esta complicação.


Pouchitis after total retocolectomy is one of the most common complication of patients with ulcerative colitis (UC), while its frequency is quite rare in familial adenomatous polyposis (FAP). PURPOSE: To evaluate the inflammatory activity in endoscopicaly normal mucosa of the ileal pouch, by determining the expression of TNF-alpha and IL-1beta, and the activation of NF-kappaB. METHODS AND PATIENTS: Twenty patients with "J" pouch after total retocolectomy were studied, being 10 patients with UC and 10 with FAP. The control group was constituted by biopsies from terminal ileum take during normal colonoscopy examination. Biopsies from mucosa of the pouch and from normal ileum were done, and they were snap-frozen in liquid nitrogen. The expression of TNF-alpha and IL-1beta were analyzed by total extract, and NF-kappaB was evaluated by immunoprecipitation and immunoblot. RESULTS: Expression of TNF-alpha and IL-1beta was increased in patients with UC, when it was compared with FAP (p<0.05). Conversely, the expression of NF-kappaB was increased in patients with UC, witch was not different from FAP. The control group had little expression of TNF-alpha (p<0.01). The activation of NF-kappaB (p>0.1) and the expression of IL-1beta (p>0.05) were similar, when comparing UC and FAP with control group. CONCLUSION: The patients with UC presented increased levels of the studied cytokines, even without clinic and endoscope evidence of pouchitis. These findings could be a suggestion of higher susceptibility to this complication among patients with UC.
