Can Diet Alter the Intestinal Barrier Permeability in Healthy People? A Systematic Review.

Dietary factors can modify the function of the intestinal barrier, causing permeability changes. This systematic review analyzed evidence on the link between diet or dietary interventions and changes in intestinal barrier permeability (IBP) in healthy individuals. A systematic search for primary studies was conducted using the virtual databases EMBASE, PubMed, Web of Science, CINAHL, and Scopus. This review adhered to PRISMA 2020 guidelines, assessing the methodological quality using the Newcastle-Ottawa scale for observational studies and ROB 2.0 for randomized clinical trials. Out of 3725 studies recovered, 12 were eligible for review. Chicory inulin and probiotics reduced IBP in adults with a moderate GRADE level of evidence. The opposite result was obtained with fructose, which increased IBP in adults, with a very low GRADE level of evidence. Only intervention studies with different dietary components were found, and few studies evaluated the effect of specific diets on the IBP. Thus, there was no strong evidence that diet or dietary interventions increase or decrease IBP in healthy individuals. Studies on this topic are necessary, with a low risk of bias and good quality of evidence generated, as there is still little knowledge on healthy populations.

Normal Values and Associated Factors in Highresolution Anorectal Manometry in Healthy Vietnamese Adults / Valores normais e fatores associados na manometria anorretal de alta resolução em adultos vietnamitas saudáveis

Abstract Introduction The present study aims to identify normal high-resolution anorectal manometry (HRAM) values and related factors in healthy Vietnamese adults. Methods The present cross-sectional study was conducted at the Viet Duc hospital, Hanoi, Vietnam, during April and May 2019. Healthy volunteers were recruited to participate in the study. Anorectal measurement values from the digestive tract, including pressure, were recorded. Results A total of 76 healthy volunteers were recruited. The mean functional anal canal length was 4.2 ± 0.5 cm, while the mean anal high-pressure zone length was 3.4 ± 0.5 cm. Themean defecation index was 1.4 ± 0.8, with values ranging from 0.3 to 5.0. The mean threshold volume to elicit the rectoanal inhibitory reflex (RAIR) was 18.1 mL. The mean rectal sensation values were 32.4mL, 81.6mL, and 159 mL for first sensation, desire to defecate, and urge to defecate, respectively. Dyssynergic patterns occurred in ~ 50% of the study participants and included mainly types I (27.6%) and III (14.6%). There were significant differences between male and female patients in terms of maximum anal squeeze pressure, maximum anal cough pressure, maximum anal strain pressure, maximum rectal cough pressure, and maximum rectal strain pressure (all p<0.01). Conclusions The present study establishes normal HRAM values in healthy Vietnamese adults, particularly regarding normal values of anorectal pressure and rectal sensation. Further studies that include larger sample sizes should be conducted to further confirm the constants and their relationships.

Predicting Maintenance of Any Breastfeeding from Exclusive Breastfeeding Duration: A Replication Study.

OBJECTIVES: To predict the duration of any breastfeeding using the duration of exclusive breastfeeding in a socioeconomically heterogeneous sample of mothers using receiver operator characteristic (ROC) analysis. STUDY DESIGN: The Mother Baby Health Survey, a birth certificate-linked cross-sectional survey was sent at 4-5 months postpartum to a stratified random sample of socioeconomically and racially diverse women in upstate New York; 797 mothers who initiated exclusive breastfeeding were included in this study. Split-sample validation was employed; eligible subjects were divided into training or test samples at random (80% and 20%, respectively). ROC curves were constructed using the training sample and optimal exclusive breastfeeding duration thresholds were tested using the remaining test sample. Logistic regression using the training sample provided estimates of the predictive ability (sensitivity, specificity, positive predictive value) of thresholds in both unadjusted and adjusted analyses (covariates: age, education, parity, marital status, and race). RESULTS: The ROC analysis in this sample demonstrated that 9 weeks of exclusivity was required for maintenance of breastfeeding at 3 months, and 14.9 weeks of exclusivity was required for maintenance at 20 weeks. Unadjusted and adjusted models yielded similar results; women who exclusively breastfed for at least 9 weeks had 2.2 times the risk (95% CI 1.7-2.8) of maintaining any breastfeeding at 3 months. CONCLUSIONS: These results are similar to our previous results, from a less diverse cohort, and support that these thresholds may be useful in clinical settings for helping mothers achieve breastfeeding duration goals.

Breastfeeding Trends Among Very Low Birth Weight, Low Birth Weight, and Normal Birth Weight Infants.

OBJECTIVE: To examine the change in breastfeeding behaviors over time, among low birth weight (LBW), very low birth weight (VLBW), and normal birth weight (NBW) infants using nationally representative US data. STUDY DESIGN: Univariate statistics and bivariate logistic models were examined using the Early Child Longitudinal Study-Birth Cohort (2001) and National Study of Children's Health (2007 and 2011/2012). RESULTS: Breastfeeding behaviors improved for infants of all birth weights from 2007 to 2011/2012. In 2011/2012, a higher percentage of VLBW infants were ever breastfed compared with LBW and NBW infants. In 2011/2012, LBW infants had a 28% lower odds (95% CI, 0.57-0.92) of ever breastfeeding and a 52% lower odds (95% CI, 0.38-0.61) of breastfeeding for ≥6 months compared with NBW infants. Among black infants, a larger percentage of VLBW infants were breastfed for ≥6 months (26.2%) compared with LBW infants (14.9%). CONCLUSIONS: Breastfeeding rates for VLBW and NBW infants have improved over time. Both VLBW and NBW infants are close to meeting the Healthy People 2020 ever breastfeeding goal of 81.9%. LBW infants are farther from this goal than VLBW infants. The results suggest a need for policies that encourage breastfeeding specifically among LBW infants.

Are the U.S. territories lagging behind in diabetes care practices?

AIMS: Although U.S. territories fall within the mandate outlined by Healthy People 2020, they remain neglected in diabetes care research. We compared the prevalence and secular trends of four recommended diabetes care practices in the U.S. territories of Guam, Puerto Rico, and the U.S. Virgin Islands to the 50 United States and D.C. ("U.S. States") in 2001-2015. METHODS: Data were from 390,268 adult participants with self-reported physician diagnosed diabetes in the Behavioral Risk Factor Surveillance System. Diabetes care practices included biannual HbA1c tests, attendance of diabetes education classes, daily self-monitoring of blood glucose, and receipt of annual foot examination. Practices were compared by U.S. territory and between territories and U.S. states. Multivariable models accounted for age, sex, education, and year. RESULTS: Of adults with diagnosed diabetes, 7% to 11% in the U.S. territories engaged in all four recommended diabetes care practices compared with 25% for those, on average, in U.S. states. Relative to the U.S. states, on average, the proportion achieving biannual HbA1c testing was lower in Guam and the U.S. Virgin Islands (45.6% and 44.9% vs. 62.2%), while annual foot examinations were lower in Puerto Rico (45.9% vs 66.1% in the U.S. states). Diabetes education and daily glucose self-monitoring were lower in all three territories. CONCLUSIONS: U.S. territories lag behind U.S. states in diabetes care practices. Policies aimed at improving diabetes care practices are needed in the U.S. territories to achieve Healthy People 2020 goals and attain parity with U.S. states.

Electrocardiographic Findings in Brazilian Adults without Heart Disease: ELSA-Brasil / Medidas Eletrocardiográficas de Adultos Brasileiros sem Cardiopatia Estabelecida: ELSA-Brasil

Abstract Background: The electrocardiogram (ECG) is widely used in population-based studies. However, there are few studies on electrocardiographic findings in Latin America and in Brazil. The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) comprised 15,105 participants (35-74 years) from six Brazilian capitals. Objectives: To describe electrocardiographic findings in Brazilian adults without heart disease, stratified by sex, age and race/skin color. Methods: Cross-sectional study with baseline data of 11,094 adults (44.5% men) without heart disease from ELSA-Brasil. The ECGs were recorded with the Burdick Atria 6100 machine and stored at the Pyramis System. ECG analysis was automatically performed using the Glasgow University software. A descriptive analysis of heart rate (HR), P, QRS and T waves' duration, PR and QT intervals, and P, R and T axes was performed. After stratification by sex, race/color and age, the groups were compared by the Wilcoxon and Kruskal-Wallis test at a significance level of 5%. Linear regression models were used to evaluate the behavior of electrocardiographic parameters over age. Major electrocardiographic abnormalities defined by the Minnesota code were manually revised. Results: Medians values of the electrocardiographic parameters were different between men and women: HR 63 vs. 66 bpm, PR 164 vs.158 ms, QT corrected 410 vs. 421 ms, QRS duration 92 vs. 86 ms, P-wave duration 112 vs. 108 ms, P-wave axis 54 vs. 57 degrees, R-wave axis 35 vs. 39 degrees, T-wave axis 39 vs. 45 degrees (p < 0.001 for all). The 2nd and the 98th percentiles of each variable were also obtained, and graphs were constructed to illustrate the behavior of the electrocardiographic findings over age of participants stratified by sex and race/skin color. Conclusions: The values for the electrocardiographic measurements herein described can be used as reference for Brazilian adults free of heart disease, stratified by sex. Our results suggest that self-reported race/skin color have no significant influence on electrocardiographic parameters.

Resumo Fundamento: O eletrocardiograma (ECG) é amplamente utilizado em estudos de base populacional. Porém, poucos desses estudos descrevem achados eletrocardiográficos na América Latina e particularmente no Brasil. O Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil) incluiu 15105 participantes (35-74 anos) de seis capitais brasileiras. Objetivos: Descrever as medidas eletrocardiográficas em adultos brasileiros não cardiopatas, estratificados por sexo, raça/cor e idade. Métodos: Estudo transversal com dados da linha de base do ELSA-Brasil (n=11094, 44,5% homens) de participantes sem doença cardiopatia prevalente. Os ECGs foram obtidos no aparelho Burdick Atria 6100 e armazenados pelo Sistema Pyramis. A análise dos ECGs foi realizada automaticamente utilizando-se o software da Universidade de Glasgow. Realizou-se análise descritiva da frequência cardíaca, da duração das ondas P, QRS e T, dos intervalos (i) PR e QT, e dos eixos de P, R e T. A comparação dos grupos estratificados por sexo, raça/cor e idade, foi feita pelos testes de Wilcoxon e Kruskal-Wallis com nível de significância definido em 5%. O comportamento das medidas eletrocardiográficas ao longo da idade foi avaliado por modelos de regressão linear. Alterações eletrocardiográficas definidas como maiores pelo código de Minnesota foram revisadas manualmente. Resultados: As medianas das mensurações foram diferentes entre homens e mulheres: FC 63 vs 66 bpm, iPR 164 vs 158 ms, iQT corrigido 410 vs. 421 ms, QRS 92 vs 86 ms, onda P 112 vs 108 ms, eixo da onda P 54 vs 58, eixo da onda R 35 vs 39 e eixo da onda T 39 vs 45 (p < 0,001 para todas). Os percentis 02 e 98 foram obtidos para cada variável analisada, assim como gráficos demonstrando o comportamento dos parâmetros eletrocardiográficos ao longo da idade dos participantes estratificados por sexo e raça/cor. Conclusões: Os valores descritos para as medidas eletrocardiográficas analisadas poderão ser utilizados como referência para adultos brasileiros sem cardiopatia prevalente, estratificados por sexo. Os resultados sugerem que não existe grande influência da raça/cor autodeclarada nas mensurações eletrocardiográficas realizadas.

Sedentarismo, deporte y la presión biopolítica de vivir saludable: análisis del discurso del sistema elige vivir sano en Chile / Sedentary lifestyle, sports and biopolitical pressure for healthy living: discourse analysis on the “choose to live healthy” system in Chile / Sedentarismo, esporte e a pressão biopolítica por uma vida saudável: análise do discurso do programa “escolha uma vida saudável”, do Chile

En la actualidad es cada vez más común escuchar a autoridades gubernamentales comentando acerca de cuál es la forma adecuada de “vivir bien” o de cómo se puede “vivir sano”. En Chile, en el año 2013 se creó la Ley Elige Vivir Sano (EVS), la cual propone generar un cambio cultural de la población, promoviendo el deporte y la actividad física como promotores de salud. Bajo un marco de referencia de la biopolítica y de la gubernamentalidad, en esta investigación se realiza un análisis de discurso a diversos documentos oficiales que construyen el discurso de EVS. Los resultados muestran que la construcción discursiva de EVS promueve una individualización del cuidado de la salud junto con la promoción del deporte y la actividad física acordes a la ideología neoliberal. Asimismo se discute respecto al tiempo libre y a las condiciones materiales que permiten o no llevar una vida sana.

It is increasingly common to hear governmental authorities commenting on the proper way to “live well” or how to “live healthy”. The so-called Choose to Live Healthy Law (Elige Vivir Sano, EVS) was created in Chile in 2013. It proposes cultural change for the population by advancing sport and physical activity as health promoters. Under a biopolitics and governmentality framework, this study uses discourse analysis to understand several official documents that build the EVS discourse. The results show that the EVS discursive construction promotes individualization of health care while advancing sport and physical activity in line with neoliberal ideology. It also discusses spare time and material conditions may allow a healthy life or not.

Na atualidade, é cada vez mais comum ouvir autoridades governamentais opinando sobre qual seria a maneira correta de se “viver bem” ou como se pode levar uma “vida saudável”. No Chile, em 2013 foi criada a Lei “Escolha uma Vida Saudável” (EVS), que propõe uma mudança cultural à população, estimulando o esporte e a atividade física como promotores de saúde. A partir de um quadro de referências relativas à biopolítica e à governamentalidade, esta pesquisa realiza uma análise do discurso de vários documentos oficiais que constroem o discurso de EVS. Os resultados mostram que a construção discursiva de EVS promove uma individualização dos cuidados de saúde, juntamente com uma promoção do esporte e da atividade física em conformidade com a ideologia neoliberal. O trabalho também discute o tempo livre e as condições materiais que permitem ou não levar-se uma vida saudável.

Gestión de gobiernos locales en la calidad de la atención de la salud para niños / Local government management regarding the quality of children's healthcare

Objetivo Evaluar el componente de calidad de los programas de atención en salud dirigidos a niños, niñas y adolescentes establecidos por los gobiernos locales de Colombia en cumplimiento de las normas legales. Métodos Estudio descriptivo en el que se evaluó la evidencia de rectoría de los sistemas de calidad y del cumplimiento de los atributos de accesibilidad, oportunidad, seguridad, continuidad y pertinencia como indicadores de la calidad en la prestación de servicios. Resultado No se encontró evidencia que demuestre que los gobiernos locales examinados desarrollen programas de salud orientados a la niñez que sean específicos a su realidad epidemiológica. Las actividades que se ejecutan corresponden al mínimo legal y no son evaluados en su componente de calidad, por tanto no hay un enfoque de mejoramiento en los mismos. Conclusión Se proponen estos resultados como línea base y dado que la función de los gobiernos locales, en materia de calidad en salud, va desde la planeación, pasando por la rectoría y el control de la calidad de los prestadores, se hace inaplazable la implementación de programas de gestión de la calidad antes que nuevos programas de atención.

Objective Assessing the quality of healthcare programs aimed at children and adolescents set by Colombian local governments in compliance with current legal standards. Methods This was a descriptive study which evaluated the evidence regarding surveillance of quality systems and compliance with accessibility, opportunity, safety, continuity and relevance as indicators of quality concerning service delivery. Results No evidence was found showing that the local governments so examined were developing child-orientated health programs specifically addressing epidemiological reality. Ongoing activities complied with minimum legal requirements and were not being evaluated regarding their quality, meaning that an approach aimed at improvement was not being adopted. Conclusion The above results are thus proposed as a working baseline and, given that the role of local government in terms of healthcare quality ranges from planning, to surveillance and quality control concerning providers, quality management programs must be implemented before new healthcare programs are introduced.

Health status of southern Arizona border counties: a Healthy Border 2010 midterm review / Situación de salud de los condados de la frontera sur de Arizona: examen a mitad de período del programa "Frontera saludable 2010"

OBJECTIVE: The region on the United States (US) side of the US-Mexico border consists of 44 counties in four states; populations on both sides of the border have similar health problems. Healthy Border 2010: An Agenda for Improving Health on the US-Mexico Border (HB 2010) is a binational agenda of health promotion and disease prevention for individuals in the region. This study reports on the health status of the four southern Arizona border counties. METHODS: Data on health indicators for Cochise, Pima, Santa Cruz, and Yuma Counties were collected from the Arizona Department of Health Services Vital Records and Statistics. Progress was calculated as a percentage made toward or away from the 2010 target. Comparisons were made between the border counties and Arizona. RESULTS: Progress toward the HB 2010 targets varied among the border counties. All border counties made progress toward the targets with the cervical cancer, hepatitis A, and teenage birthrate objectives. Most border counties moved toward the goals for breast cancer, diabetes mortality, tuberculosis, motor vehicle crashes, infant mortality from congenital abnormalities, and prenatal care. Border counties moved away from the target with the human immunodeficiency virus and infant mortality objectives. CONCLUSIONS: Assessment of the HB 2010 objectives provided a comprehensive description of the health status of the population. Although the southern Arizona border counties have shown improvement in some areas, monitoring is still needed to identify the disparities that remain.

OBJETIVO: La región estadounidense de la frontera entre México y los Estados Unidos consta de 48 condados distribuidos en cuatro estados, y las poblaciones que viven a uno y otro lado de la frontera tienen problemas de salud similares. El programa binacional "Frontera saludable 2010" está destinado a las poblaciones de la región y se propone mejorar la situación sanitaria en la frontera entre México y los Estados Unidos mediante actividades de promoción de la salud y prevención de enfermedades. Este estudio es un informe sobre la situación sanitaria de los cuatro condados de la frontera sur de Arizona. MÉTODOS. Los datos acerca de los indicadores de salud de los condados de Cochise, Pima, Santa Cruz y Yuma se obtuvieron del registro civil y estadísticas del Departamento de Servicios de Salud de Arizona. Se calculó el progreso mediante un porcentaje que refleja la cercanía o la lejanía del objetivo propuesto para el año 2010. Se compararon los datos correspondientes a los condados fronterizos con los del estado de Arizona. RESULTADOS: El progreso hacia los objetivos del programa "Frontera saludable 2010" no fue uniforme en los distintos condados fronterizos. Los cuatro condados lograron avances hacia los objetivos propuestos en materia de cáncer cervicouterino, hepatitis A y tasa de natalidad entre las adolescentes. La mayoría de los condados fronterizos están más próximos a cumplir con los objetivos en materia de cáncer de mama, mortalidad por diabetes, tuberculosis, colisiones de vehículos automotores, mortalidad infantil por anomalías congénitas y atención prenatal. Sin embargo, ninguno de los cuatro condados se está acercando al objetivo propuesto en cuanto al virus de la inmunodeficiencia humana y la mortalidad infantil. CONCLUSIONES: La evaluación de los objetivos del programa "Frontera saludable 2010" brindó una descripción integral de la situación de salud de la población. Aunque los condados de la frontera sur de Arizona han logrado avances en algunos aspectos, sigue siendo necesario mantener la vigilancia con el fin de detectar las disparidades aún presentes.
