Diabetes tipo II. A terapia periodontal não cirúrgica pode favorecer o controle glicêmico do paciente? / Type II Diabetes. Does nonsurgical periodontal therapy improve glycemic control in patientes? / Diabetes tipo II. ¿Puede la terapia periodontal no quirúrgica mejorar el control glicémico del paciente?

Introdução:A doença periodontal corresponde àcondição que acomete os tecidos de proteção e/ou suporte do dente através de uma inflamação crônica causadapor patógenos.Estacondição pode ser modificada ou associada às doenças sistêmicas, como por exemplo, o diabetes mellitus tipo II (DM2).Objetivo:Avaliar quais os efeitos da terapia periodontal não cirúrgica sobre o controle glicêmico de pacientes diagnosticados com DM2.Metodologia:Revisão integrativa elaborada a partir de pesquisas clínicas randomizadas indexadas nas bases de dados Pubmed, Embase, Cochrane, Web of Science e BVS, na qual foram utilizados os descritores "periodontal diseases treatment", "glycemic control" e "metabolic control".Resultados:Dos trabalhos avaliados, seis foram selecionados para compor a revisão, tendo em vista os critérios de inclusão e exclusão estabelecidos. Logo, é notório que a terapia periodontal básica indica melhora no controle glicêmico dos pacientes com DM2, de acordo comanálise da HbA1c e PCR,portanto, com base nos resultados dessa pesquisa, o tratamento periodontal não cirúrgico parece contribuir para o controle metabólico. Apesar disso, alguns estudos se opõem aoresultadodo controle glicêmicodesses pacientes, reforçando a existência de variáveis que interferem nos resultados da pesquisa, como os níveis de hemoglobina, estágio da doença periodontal, amostra, dietae atividade física dos pacientes.Conclusões:O resultado deverá ser avaliado com maior cautela, tendo em vista as possibilidades de variáveis presentes nesse tipo de pesquisa. Por fim, ensaios controlados devem ser realizados para alcançar um maior esclarecimento a respeito dos efeitos da terapia periodontal não cirúrgica no controle glicêmico de pacientes com DM2 (AU).

Introduction:Periodontal disease is a condition in which protective or supportive tissues of the tooth are affected by chronic inflammation caused by pathogens. This condition may be modified or associated with systemic diseases such as type 2 diabetes mellitus (T2DM).Objective:To evaluate the effects of nonsurgical periodontal therapy on glycemic control in patients diagnosed with T2DM. Methodology:An integrative review was performed using randomized clinical trials indexed in PubMed, Embase, Cochrane, Web of Science, and BVS databases. The descriptors "periodontal disease treatment," "glycemic control," and "metabolic control" were used. Results:From the reviewed studies, six were selected for the review considering the established inclusion and exclusion criteria.Basic periodontal therapy improves glycemic control in patients with T2DM, as evidenced by analysis of glycated hemoglobin (HbA1c) and polymerase chain reaction (PCR). Therefore, based on the results of this research, nonsurgical periodontal treatment contributes to metabolic control. However, some studies contradict the effect of glycemic control in these patients, reinforcing the presence of variables that interfere with research results, such as hemoglobin levels, stage of periodontal disease, sample, dietand physical activity of patients. Conclusions:The results should be evaluated with more caution considering the potential variables present in this type of research. Finally, controlled trials should be conducted to understand better the effects of nonsurgical periodontal therapy on glycemic control in patients with T2DM (AU).

Introducción: La enfermedad periodontal es una condición en la cual los tejidos protectores o de soportedel diente se ven afectados por una inflamación crónica causada por patógenos. Esta condición puede modificarse o asociarse a enfermedades sistémicas como la diabetes mellitus tipo 2 (DM2). Objetivo: Evaluar los efectos de la terapia periodontal no quirúrgica en el control glucémico en pacientes diagnosticados con DM2. Metodología: Se realizó una revisión integradora utilizando ensayos clínicos aleatorizados indexados en las bases de datos de PubMed, Embase, Cochrane, Web of Science y BVS. Se utilizaron los descriptores "tratamiento de enfermedades periodontales", "control glucémico" y "control metabólico". Resultados: De los estudios revisados, se seleccionaron seis para la revisión, considerando los criterios de inclusión y exclusión establecidos. La terapia periodontal básica mejora el control glucémico en pacientes con DM2, como se evidencia en el análisis de la hemoglobina glicosilada (HbA1c) y la reacción en cadena de la polimerasa (PCR). Por lo tanto, basándose en los resultados de esta investigación, el tratamiento periodontal no quirúrgico contribuye al control metabólico. Sin embargo, algunos estudios contradicen el efecto del control glucémico en estos pacientes, lo que refuerza la presencia de variables que interfieren en los resultados de la investigación, como los niveles de hemoglobina, el estadio de la enfermedad periodontal, la muestra, la dieta y la actividad física de los pacientes. Conclusiones: Los resultados deben evaluarse con mayor precaución, considerando las posibles variables presentes en este tipo de investigación. Por último, se deben realizar ensayos controlados para comprender mejor los efectos de la terapia periodontal no quirúrgica en el control glucémico en pacientes con DM2 (AU).

ALULOSA COMO ENDULZANTE ALTERNATIVO PARA REDUCIR EL ÍNDICE GLUCÉMICO Y LAS CALORÍAS DE LOS ALIMENTOS: ASPECTOS BIOLÓGICOS, LEGALES Y TECNOLÓGICOS / ALLULOSE AS AN ALTERNATIVE SWEETENER TO REDUCE THE GLYCEMIC INDEX AND CALORIES OF FOODS: BIOLOGICAL, LEGAL AND TECHNOLOGICAL ASPECTS

La obesidad y la prevalencia de la diabetes han aumentado progresivamente en los últimos decenios, lo cual ha conllevado a diversas recomendaciones de la Organización Mundial de la Salud (OMS) para mejorar la dieta e incorporar hábitos saludables. Con el objetivo de limitar los azúcares agregados, reducir las calorías y modular la respuesta glucémica, la industria ha implementado distintas alternativas, entre las cuales ciertos azúcares raros presentan un gran potencial. La alulosa, como sustituto de azúcares tradicionales y edulcorantes, confiere características sensoriales similares a las de los productos con sacarosa y proporciona los beneficios nutricionales esperados. El objetivo de este trabajo fue revisar los conocimientos, hasta la fecha, sobre aspectos biológicos, legales y tecnológicos de la alulosa

The obesity and prevalence of type 2 diabetes have progressively increased in the recent decades, which has led to various recommendations from the World Health Organization (WHO) to improve diet and healthy habits. With the objective of limiting added sugars, reducing calories, and modulating the glycemic response, the industry has implemented different alternatives, among which certain rare sugars have great potential. Allulose as a substitute for traditional sugars and sweeteners confers sensory characteristics like those of products with sucrose and provides the expected nutritional benefits. The aim of this work was to look over the knowledge, to date, on biological, legal, and technological aspects of allulose

Association of glycemic index using HbA1c and sensorineural hearing loss in diabetes mellitus type 2 patients: A systematic review and meta-analysis

Objective@#To systematically review the available evidence on the association of HBA1c levels and development of sensorineural hearing loss and to quantitatively analyze the available data on HBA1c levels in patients with type 2 diabetes mellitus and sensorineural hearing loss to determine an HbA1c level that may be associated with the risk of having sensorineural hearing loss.@*Methods@#Design: Systematic Review and Meta-analysis Eligibility Criteria: Cross-sectional studies, or cohort studies which were limited to English language that investigated the correlation of glycemic index using HBA1c and sensorineural hearing loss among adult type 2 diabetic patients which were done from January 2010 to December 2021. Studies with no published outcome, incomplete data or that were ongoing as of August 1, 2022 were also excluded. Information Sources: MEDLINE (through PubMed), Cochrane Library, Scopus, Embase (through OVID@journal), Directory of Open Access Journals (DOAJ), Google Scholar and HERDIN Plus Risk of Bias: Risk of Bias was assessed using the Guidelines for Cochrane Collaboration Synthesis of Results: Results were presented using forest plots for representation.@*Results@#A total of 8 studies were reviewed with 2,103 participants in all. Six articles compared hearing loss incidence between diabetic and non-diabetic patients. Overall, there were a total of 881 diabetic patients and 1222 non-diabetic patients. There was a significantly lower incidence of sensorineural hearing loss in non-diabetic patients with a risk ratio of 1.89, 95% CI [1.65, 2.16]. Three articles compared the HbA1c levels of diabetic patients with or without sensorineural hearing loss. Diabetic patients without sensorineural hearing loss had significantly lower HbA1c levels compared to those with sensorineural hearing loss with mean difference of 1.04, 95%CI [0.82, 1.25].@*Conclusion@#In conclusion, this meta-analysis showed a higher prevalence rate of sensorineural hearing loss among patients with diabetes mellitus compared to non-diabetic patients. Moreover, poor glycemic control among diabetic patients with a glycemic index based on HbA1c of more than 8.3 (6.97-9.6) is associated with sensorineural hearing loss.

Estrategias para mitigar hipoglucemias y variabilidad glucémica / Strategies to mitigate hypoglycemia and glycemic variability

La última década se ha destacado por los importantes avances en el desarrollo de nuevas tecnologías para pacientes que viven con diabetes mellitus (DM). Las innovaciones han estado orientadas principalmente a: mejorar la calidad de vida, reducir el impacto que genera la ocurrencia de hipoglucemias y reducir la carga de la enfermedad colaborando en la toma diaria de decisiones1. El monitoreo continuo de glucosa (MCG) es una herramienta que ha experimentado un importante avance al aportar información dinámica del estado metabólico en los pacientes y permitir la toma de decisiones, demostrado por un control metabólico estable, menores excursiones glucémicas, y una reducción significativa en la aparición y gravedad de las hipoglucemias2-5. Las presentes recomendaciones tienen como objetivo brindar herramientas rápidas para la interpretación de datos metabólicos y la consiguiente toma de decisiones terapéuticas. A tal fin se realizó una exhaustiva revisión de las principales guías y recomendaciones vigentes; posteriormente, el Grupo de Trabajo adaptó esa información según una serie de preguntas con criterio clínico práctico. El avance de los MCG es innegable, no solo en el desarrollo tecnológico, sino que se han convertido en una herramienta educativa para las personas con DM, su entorno y el equipo de salud al posibilitar un ajuste dinámico del tratamiento, prevenir complicaciones agudas y mejorar la calidad de vida. En esta ecuación enfatizamos la importancia de la educación diabetológica continua de la persona con DM y su entorno, participando activamente en la toma de decisiones para, de esta manera, cumplir con los objetivos propuestos: mejorar la calidad de vida, reducir la carga de la enfermedad y disminuir las excursiones glucémicas agudas.

The last decade has been highlighted by important advances in the development of new technologies for patients living with diabetes. The innovations have been oriented above all to improve the quality of life, reduce the impact generated by the occurrence of hypoglycemia and reduce the burden of the disease by collaborating in daily decision-making1. Continuous glucose monitoring (CGM) is a tool that has undergone significant progress, providing dynamic information on the metabolic status of patients, allowing decision making, demonstrated by stable metabolic control, lower glycemic excursions and a significant reduction in the occurrence and severity of hypoglycemia2-5. The purpose of these recommendations, developed by members of the Innovation Committee of the Argentine Society of Diabetes, is to provide rapid tools for the interpretation of metabolic data and the subsequent therapeutic decisionmaking. To this end, an exhaustive review of the main current guidelines and recommendations has been carried out, later the working group adapted this information according to a series of questions with practical clinical criteria. The progress of CGMs is undeniable, not only in technological development, but it has become an educational tool for people with diabetes, their environment, and the health team, offering the possibility of a dynamic adjustment of treatment, prevention of acute complications and improving quality of life. In this equation, we emphasize the importance of continuous diabetes education for the person with diabetes and their environment, actively participating in decision-making, and in this way, meeting the proposed objectives: improving quality of life, reducing the burden of disease, and decreasing acute glycemic excursions.

Índice leucoglucémico en pacientes con infarto miocárdico con elevación del ST / Leuko-glycemic index in patients with ST elevation myocardial infarction

Introducción: la mortalidad asociada a infarto del miocardio (IM) no solo se debe a complicaciones cardiovasculares, sino también a complicaciones intrahospitalarias no cardiovasculares (CIHNC). El índice leuco-glucémico (ILG) se ha utilizado como un marcador pronóstico para el desarrollo de complicaciones cardiovasculares en el IM. Centramos este estudio en identificar el punto de corte de ILG para el desarrollo de CIHNC en pacientes con infarto de miocardio con elevación del segmento ST (IAMCEST). Material y métodos: en este diseño de un solo centro y transversal, incluimos pacientes con IAMCEST. El análisis bioquímico incluyó glucosa y leucocitos; se calculó ILG. Se realizaron análisis univariados y bivariados, curva ROC y análisis multivariado para el desarrollo de IAMCEST. Resultados: incluimos 1294 pacientes, 79.8% hombres y 20.2% mujeres. Las principales comorbilidades fueron: hipertensión arterial sistémica, diabetes mellitus y dislipidemia. Seiscientos cuarenta y cuatro pacientes (49.8%) presentaron CIHNC. El ILG > 1200 con área bajo la curva (AUC) 0.817 predice el desarrollo de CIHNC en pacientes con IAMCEST. Las variables que aumentaron el desarrollo de CIHNC fueron: ILG > 1200, creatinina > 0.91 mg/dL, diabetes mellitus y edad > 65 años. La neumonía intrahospitalaria y las complicaciones cardiovasculares aumentaron el riesgo de muerte entre los pacientes con IAMCEST. Conclusión: un LGI > 1200 aumentó más de nueve veces el riesgo de desarrollo de CIHNC en pacientes con IAMCEST.

Background: The myocardial infarction-associated (MI) mortality is not only due cardiovascular complications, but intrahospital non-cardiovascular complications (IHnCVCs). The leuko-glycemic index (LGI) has been used as a prognostic marker for the development of cardiovascular complications in MI. We focused this study on identifying the cut-off point of LGI for the IHnCVCs development in patients with ST-segment elevation myocardial infarction (STEMI).Material and methods: In this single-center and cross-sectional design, we included patients with STEMI. The biochemical analysis included glucose and leucocytes; with them we calculated the LGI. Receiver operating characteristic curve, univariate and bivariate analysis, and multivariate analysis for IHnCVCs development were performed. A p < 0.05 was considered statistically significant. Results: We included 1294 patients, 79.8% were men and 20.2% women. The main comorbidities were hypertension, diabetes mellitus and dyslipidemia. Six hundred forty-four (49.8%) patients presented IHNCVCs. The LGI > 1200 (AUC 0.817) predict the IHNCVCs development in STEMI patients. The variables that increased the IHNCVCs development were LGI > 1200, creatinine > 0.91 mg/dL, diabetes mellitus and age > 65 years. Hospital acquired pneumonia and cardiovascular complications increase the risk of death among STEMI patients. Conclusion: A LGI > 1200 increased, just over nine times, the risk of IHnCVC development in STEMI patients.

Avaliação do consumo de frutas em pacientes com diabetes mellitus tipo 2 / Fruit consumption in patients with type 2 diabetes mellitus

Introdução: O impacto do consumo de frutas sobre a saúde de pacientes com diabetes mellitus tipo 2 (DM2) requer investigações. O objetivo deste estudo foi avaliar o consumo de frutas em pacientes com DM2 e identificar a sua associação com parâmetros de controle glicêmico.Métodos: Foram incluídos 197 pacientes ambulatoriais com DM2, submetidos à avaliação clínica, sociodemográfica, antropométrica, laboratorial e de consumo alimentar. A ingestão alimentar total e o consumo de frutas foram avaliados por questionário quantitativo de frequência alimentar. Os pacientes com menor e maior consumo de frutas (de acordo com a mediana) foram comparados.Resultados: A média do consumo de frutas foi de 593,66 ± 330,74 g/dia. Entre os menores e maiores consumidores de frutas, os valores de glicemia (169,42 ± 70,83 vs. 158,62 ± 64,56 mg/dL; p = 0,273) e hemoglobina glicada (8,39 ± 1,68 vs. 8,68 ± 2,38%; p = 0,319) não foram diferentes, assim como as demais variáveis. Os pacientes com maior consumo de frutas apresentaram maior ingestão de energia (p < 0,001), carboidratos (p < 0,001) e fibras (p = 0,006) e uma menor ingestão de proteínas (p = 0,015), lipídeos totais (p = 0,040) e seus tipos. O grupo que mais consumiu frutas apresentou uma maior ingestão de vitamina C (p < 0,001) e potássio (p < 0,001) e um menor consumo de sódio (p = 0,001). Foi observado ainda uma correlação negativa entre o consumo de frutas e o índice glicêmico da dieta (p = 0,05).Conclusão: Não houve diferença na glicemia em jejum e no valor de hemoglobina glicada entre os pacientes com DM2 com maior e menor consumo de frutas.

Introduction: The impact of fruit consumption on the health of patients with type 2 diabetes mellitus (T2DM) warrants investigation. The aim of this study was to evaluate fruit consumption in patients with T2DM and to identify its association with glycemic control parameters.Methods: We included 197 outpatients with T2DM who underwent clinical, sociodemographic, anthropometric, laboratory, and food consumption assessments. A food frequency questionnaire was used to assess total food intake and fruit consumption. Patients with lower and higher fruit consumption (according to the median) were compared.Results: Average fruit consumption was 593.66 ± 330.74 g/day. Blood glucose (169.42 ± 70.83 vs. 158.62 ± 64.56 mg/dL; p = 0.273) and glycated hemoglobin (8.39 ± 1.68% vs. 8.68 ± 2.38%; p = 0.319) levels did not differ between the lower and higher fruit consumption groups, nor did the other variables. Patients with higher fruit consumption had a higher intake of energy (p < 0.001), carbohydrates (p < 0.001), and fibers (p = 0.006) but a lower intake of proteins (p = 0.015) and total and different types of lipids (p = 0.040). The higher consumption group had higher vitamin C (p < 0.001) and potassium (p < 0.001) intake and lower sodium intake (p = 0.001). We identified a negative correlation between fruit consumption and the diet's glycemic index (p = 0.05).Conclusion: Fasting blood glucose and glycated hemoglobin levels did not differ between the higher and lower fruit consumption groups.

Prognostic Value of the Leuko-Glycaemic Index in the Postoperative Period of Coronary Artery Bypass Grafting

Abstract Introduction: High leuko-glycaemic index (LGI) (> 2000) has been associated with poor prognosis in many critical care settings. However, there is no evidence of LGI's prognostic value in the postoperative period of coronary artery bypass grafting (CABG). This study aims to analyze the prognostic value of LGI in the postoperative period of CABG. Methods: Single-center retrospective analysis of prospectively collected data was performed. Consecutive adult patients undergoing CABG between 2007 and 2019 were included. Blood glucose levels and white blood cells count were evaluated in the immediate postoperative period. LGI was calculated by multiplying both values and dividing them by 1,000 and analyzed in quartiles. Receiver operating characteristic curve was used to determine the best cutoff value. The primary combined endpoint was in-hospital mortality, low cardiac output (LCO), or acute kidney injury (AKI). Secondary endpoints included in-hospital death, AKI, atrial fibrillation, and LCO. Results: The study evaluated 3,813 patients undergoing CABG (88.5% male, 89.8% off-pump surgery, aged 64.6 years [standard deviation 9.6]). The median of LGI was 2,035. Presence of primary endpoint significantly increased per LGI quartile (9.2%, 9.7%, 11.8%, and 15%; P<0.001). High LGI was associated with increased occurrence of in-hospital mortality, LCO, AKI, and atrial fibrillation. The best prognostic cutoff value for primary endpoint was 2,000. In a multivariate logistic regression model, high LGI was independently associated with in-hospital death, LCO, or AKI. Conclusion: High LGI was an independent predictor of in-hospital mortality, LCO, or AKI in postoperative period of CABG. It was also associated with higher in-hospital death.

El promedio del índice leucoglucémico fue de 1,578.41 ± 1,208.1 y el punto de corte establecido fue de 656.8, de acuerdo con la curva ROC, con sensibilidad del 95.8% y especificidad del 73% para la predicción de complicaciones intrahospitalarias, con OR de 7.89. Conclusión: Un índice leucoglucémico > 656.8 representa un riesgo de 7.89 veces de desarrollar complicaciones en la población estudiada.

Abstract Introduction: Leukoglycemic index is a poorly known and used prognostic factor that correlates blood glucose and leukocytes which are taken at hospital admission. Its importance lies in determining complications and mortality risks in patients with acute myocardial infarction. Objective: To establish the leukoglycemic index as a predictor of complications during the in-hospital evolution in patients with acute myocardial infarction. Methods: Epidemiological, observational, cross-sectional, crosssectional study on a cohort of patients admitted with acute myocardial infarction during a period of 1 year 3 months. Results: 205 patients with acute myocardial infarction were included in this study. The mean age was 62.99 ± 12.2 years old, more frequently in males by 69.3%. It was determined that acute myocardial infarction with ST elevation predominated both in frequency with 63.9%, as well as with a higher rate of complications (p < 0.001). The average of leukoglycemic index was 1578.41 ± 1208.1 and the cut-off point was 656.8, according to ROC curve, with sensitivity of 95.8% and specificity of 73% for the prediction of inhospital complications, OR 7.89. Conclusions: A leukoglycemic index greater than 656.8 represents a 7.89-fold risk of developing complications in the study population.

Subclinical ketosis risk prediction in dairy cows based on prepartum metabolic indices / [Previsão do risco de cetose subclínica em vacas de leite, baseado nos índices metabólicos pré-parto]

Ketosis can seriously impair cow performance. This study detected changes in prepartum blood metabolic parameters for predicting postpartum ketosis occurrence in dairy cows. Body condition score (BCS) was assessed before and after delivery. Blood samples of 63 cows were collected from 10 days before calving to 10 days after calving to measure metabolic parameters including ß-hydroxybutyric acid (BHBA), non-esterified fatty acid (NEFA), glucose (GLU), total bilirubin (TBIL), direct bilirubin (DBIL), indirect bilirubin (IBIL), total protein (TP), albumin (ALB), globulin (GLO), alanine aminotransferase (ALT), and aspartate aminotransferase (AST). There was a postpartum subclinical ketosis incidence of 42.25%. Compared with prepartum, plasma, levels of BHBA, AST, and NEFA significantly increased postpartum, and prepartum AST (R=0.57) and NEFA (R=0.45) showed a significant positive correlation with ketosis postpartum. Plasma GLU level significantly decreased postpartum and was significantly negatively correlated with ketosis (R=-0.21). Receiver operating characteristic curve analysis revealed prepartum BSC < 2.88, and prepartum plasma AST > 68.0 U/L, GLU < 3.97mmol/L, NEFA > 0.27mmol/L, and BHBA > 0.43mmol/L, indicating a high risk of subclinical ketosis postpartum. These levels can be used as risk indicators to predict the occurrence of subclinical ketosis in postpartum cows.(AU)

A cetose pode trazer sérios prejuízos ao desempenho da vaca. Este estudo detectou alterações nos parâmetros metabólicos do sangue pré-parto para prever a cetose pós-parto que ocorre em vacas leiteiras. O escore de condição corporal (ECC) foi avaliado antes e após o parto. Foram coletadas amostras de sangue de 63 vacas entre 10 dias antes e 10 dias após o parto para medir os parâmetros metabólicos, incluindo ácido ß-hidroxibutírico (BHBA), ácido graxo não esterificado (NEFA), glicose (GLU), bilirrubina total (TBIL), bilirrubina direta (DBIL), bilirrubina indireta (IBIL), proteína total (TP), albumina (ALB), globulina (GLO), alanina aminotransferase (ALT) e aspartato aminotransferase (AST). Houve uma incidência de cetose subclínica pós-parto de 42,25%. Em comparação com o pré-parto, o plasma, os níveis de BHBA, AST e NEFA aumentaram significativamente no pós-parto, e AST no pré-parto (R = 0,57) e NEFA (R = 0,45) mostraram uma correlação significativa positiva com cetose pós-parto. O nível plasmático de GLU diminuiu significativamente no pós-parto e foi negativamente correlacionado com a cetose de forma significativa (R = -0,21). A análise da curva característica de operação do receptor revelou BSC pré-parto <2,88 e AST plasmático pré-parto> 68,0 U / L, GLU <3,97mmol / L, NEFA> 0,27mmol / L e BHBA> 0,43mmol / L, indicando um alto risco de cetose subclínica pós-parto. Esses níveis podem ser usados ​​como indicadores de risco para prever a ocorrência de cetose subclínica em vacas no pós-parto.(AU)

The effects of kefir in mixed meals on appetite and food intake: a randomized cross-over trial / Os efeitos do quefir em refeições mistas sobre o apetite e a ingestão de alimentos: um estudo randomizado cruzado

ABSTRACT Objective The natural probiotic kefir is fermented milk, and may have effects on satiety and voluntary energy intake. This randomized crossover trial aimed to determine whether kefir, consumed with low- or high-glycemic index meals, affects appetite and subsequent food intake. Methods Twenty four healthy females aged 21-24 years, were recruited from Erciyes University and the surrounding community. The participants were submitted to three different breakfasts: a low glycemic index accompanied by milk, a low glycemic index with kefir, and a high glycemic index with kefir, with a 1-week washout period between meals. At 0, 15, 30, 60, 90, 120, 150, and 180 minutes after the meal, appetite ratings were measured by the visual analog scale, and then ad libitum lunch was served. Results No differences in appetite scores and voluntary energy intake were detected between the test meals. Furthermore, palatability ratings were similar between test meals, except for the higher score of high glycemic index kefir for overall palatability. Conclusion This study demonstrated that adding kefir to a high glycemic index meal may prevent increases in appetite and food intake, resulting in postprandial responses similar to those of a low glycemic index meal. These findings might enable the development of novel dietary strategies based on appetite regulation to treat or prevent obesity, particularly for Western societies. This trial was registered at ClinicalTrials.gov under the process NCT03636217.

RESUMO Objetivo O quefir probiótico natural é um leite fermentado, e pode ter alguns efeitos sobre a saciedade e a ingestão voluntária de energia. Este ensaio cruzado randomizado teve como objetivo determinar se o quefir consumido com uma refeição de baixo ou alto índice glicêmico teria afetado o apetite e a ingestão de alimentos subsequente. Métodos Vinte e quatro mulheres saudáveis, com idades entre 21 e 24 anos, foram recrutadas na Universidade de Erciyes e na comunidade circundante. Todas as participantes foram submetidas a três cafés da manhã diferentes: um baixo índice glicêmico e leite, um baixo índice glicêmico e quefir, e um alto índice glicêmico e quefir, com um período de lavagem de 1 semana entre as refeições. Aos 0, 15, 30, 60, 90, 120, 150 e 180 minutos após a refeição, as classificações de apetite foram medidas por escala analógica visual e, em seguida, o almoço ad libitum foi servido. Resultados Não foram detectadas diferenças nos escores do apetite e na ingestão voluntária de energia entre as refeições do teste. Além disso, as classificações de palatabilidade foram semelhantes entre as refeições de teste, exceto o maior escore de alto índice glicêmico quefir para palatabilidade geral. Conclusão Este estudo demonstrou que a adição de quefir a uma refeição com alto teor de índice glicêmico pode impedir o aumento do apetite e da ingestão de alimentos, resultando em respostas pós-prandiais semelhantes a uma refeição com baixo teor de índice glicêmico. Esses achados poderiam permitir o desenvolvimento de novas estratégias dietéticas baseadas na regulação do apetite para tratar ou prevenir a obesidade, particularmente para a sociedade ocidental. Esse julgamento foi registado na ClinicalTrials.gov como NCT03636217.

Inverted U-Shaped Associations between Glycemic Indices and Serum Uric Acid Levels in the General Chinese Population: Findings from the China Cardiometabolic Disease and Cancer Cohort (4C) Study / 生物医学与环境科学（英文）

Objective@#The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.@*Methods@#The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.@*Results@#A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).@*Conclusion@#An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

Valores de riesgo vascular de indicadores metabólicos en adolescentes y ancianos de La Habana / Vascular Risk Values of Metabolic Indicators in Adolescents and Elderlies from Havana

Introducción: Durante el ciclo de vida de los individuos son imprescindibles intervenciones para detectar y reducir el riesgo y las complicaciones de las enfermedades crónicas. Objetivo: Determinar la prevalencia de valores de riesgo vascular de los principales indicadores del metabolismo glucídico y lipídico en adolescentes y ancianos de La Habana. Métodos: Se realizó un estudio transversal en una muestra conformada por adolescentes (469 de 12-16 años) aparentemente sanos y ancianos (395 de 65-100 años) sin diagnóstico de enfermedades asociadas a la alteración marcada del estado nutricional y metabólico. Ambas poblaciones fueron evaluadas para glucosa, triglicéridos, colesterol total, colesterol de lipoproteinas de alta densidad y colesterol de lipoproteínas de baja densidad, séricos, mediante métodos enzimáticos convencionales. Se usaron rangos de riesgo referentes. Los resultados se analizaron mediante estadística descriptiva. Resultados: En los adolescentes evaluados, los triglicéridos (35,6 por ciento) y el colesterol total (23,9 por ciento) mostraron las mayores frecuencias de valores de riesgo. En las hembras ambos marcadores se mantuvieron como los más elevados en ese orden, mientras que, en los varones, la glucosa (25,5 por ciento) secundó a los triglicéridos como indicadores más alterados. En ancianos, al colesterol de lipoproteínas de baja densidad (58,2 por ciento) y al colesterol total (48,6 por ciento) correspondieron las mayores frecuencias de cifras de riesgo, patrón que se repitió en cada sexo. Los valores promedio de los indicadores fueron marcadamente superiores en ancianos que, en adolescentes, excepto para glucosa y colesterol de lipoproteínas de alta densidad. Conclusiones: Los resultados obtenidos muestran una elevada prevalencia de valores de riesgo vascular de varios indicadores metabólicos evaluados en adolescentes y ancianos, lo que sugiere la necesidad de monitorear los indicadores analizados e implementar intervenciones modificadoras de sus valores hacia la reducción del riesgo asociado, desde etapas tempranas, como las previas a la adolescencia(AU)

Introduction: During the life cycle of individuals, interventions are essential to detect and reduce the risk and complications of chronic diseases. Objective: To determine the prevalence of vascular risk values of the main indicators of carbohydrate and lipid metabolism in adolescents and elderlies in Havana. Methods: A cross-sectional study was carried out with a sample made up of apparently healthy adolescents (469; aged 12-16 years) and elderlies (395 aged 65-100 years) without a diagnosis of diseases associated with marked alteration of nutritional and metabolic status. Both populations were evaluated regarding serum glucose, triglycerides, total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol using conventional enzymatic methods. Reference risk ranges were used. The results were analyzed using descriptive statistics. Results: In the evaluated adolescents, triglycerides (35.6 percent) and total cholesterol (23.9 percent) showed the highest frequencies of risk values. In females, both markers remained the highest in that aspect; while in males, glucose (25.5 percent) accounted second after triglycerides as the most altered indicators. In the elderlies, low-density lipoprotein cholesterol (58.2 percent) and total cholesterol (48.6 percent) corresponded to the highest frequencies of risk values, a pattern that was repeated in each sex. The average values of the indicators were markedly higher in the elderlies than in adolescents, except for glucose and high-density lipoprotein cholesterol. Conclusions: The results obtained show high prevalence of vascular risk values of several metabolic indicators evaluated in adolescents and elderlies, which suggests the need to monitor the analyzed indicators and implement interventions to modify such values, in view of reducing the associated risk, from stages early, such as the pre-adolescence stage(AU)

Avaliação da correlação diagnóstica dos níveis de HbA1c e microalbuminúria em pacientes com Diabetes mellitus tipo 2 como marcador de prevenção de complicações renais / Evaluation of the diagnostic correlation of HbA1c and microalbuminuria levels in type 2 Diabetes mellitus patients as a marker of prevention of renal complications

Objetivo: Avaliar a correlação entre os níveis de hemoglobina glicada A1c (HbA1c) e os valores de microalbuminúria como parâmetro auxiliar no diagnóstico precoce de dano renal. Métodos: Analisaram-se 56 pacientes que apresentaram os exames de glicemia de jejum, HbA1c e microalbuminúria, durante o período de um ano em um laboratório do município de Videira-SC. A análise dos dados foi realizada pelo teste de correlação de Pearson's estabelecendo como valores estatisticamente significativos p < 0,05. Resultados: Os valores de glicose de jejum se apresentaram alterados em ambos os sexos e faixa etária. Na hemoglobina glicada indivíduos do sexo feminino com faixa etária de até 60 anos de idade demostraram maiores alterações no controle glicêmico. Para os resultados de micro­albuminúria, 68% dos participantes apresentaram valores normais e 32% exibiram valores acima dos de referência, indicando presença de microalbuminúria e possível dano renal. Os valores mostraram correlação entre microalbuminúria e HbA1c em mulheres e homens respectivamente (p < 0,0001). Conclusão: Quando os valores de HbA1c apresentaram-se aumentados consequentemente os valores de microalbuminúria também estavam elevados. Portanto, a utilização desses marcadores na busca de identificar danos renais é fundamental.

Objective:This study aimed to evaluate the correlation between the levels of glycated hemoglobin A1c (HbA1c) and the values of microalbuminuria as an auxiliary parameter in the early diagnosis of kidney damage. Methods: Fifty-six patients who had fasting blood glucose, HbA1c and microalbuminuria tests were analyzed during a period of one year in a laboratory in the municipality of Videira-SC. Data analysis was performed using Pearson's correlation test, establishing as statistically significant values p < 0.05. Results: Fasting glucose values were altered in both sexes and age groups. In glycated hemoglobin, female individuals aged up to 60 years old showed greater changes in glycemic control. For the results of microalbuminuria, 68% of the participants had normal values and 32% showed values above those of reference, indicating the presence of microalbuminuria and possible kidney damage. The values showed a correlation between microalbuminuria and HbA1c in women and men respectively (p <0.0001). Conclusion: When the HbA1c values were consequently increased, the microalbuminuria values were also high. Therefore, the use of these markers in the search to identify kidney damage is essential.

Restrição de carboidratos no manejo do diabetes mellitus tipo 2: revisão crítica de ensaios clínicos randomizados / Carbohydrate restriction in the management of diabetes mellitus type 2: critical review of randomized clinical tests

O diabetes mellitus tipo 2 (DM2) é considerado um dos principais distúrbios metabólicos relacionados ao desenvolvimento de doenças cardiovasculares e outras comorbidades, com elevada incidência e prevalência no Brasil e no mundo. Apesar dos avanços em seu tratamento, a projeção mundial é de aumento no número de diagnósticos. No Brasil, o total de pessoas com a doença cresceu mais de 60% em 10 anos. Como o manejo dietético é um dos pilares no tratamento do DM2, este trabalho objetivou analisar os estudos que compararam as dietas restritas em carboidratos com outras abordagens dietéticas a fim de elucidar se esta seria a opção mais adequada para os pacientes com DM2. Assim, fez-se uma revisão de ensaios clínicos randomizados por meio das plataformas de pesquisa PubMed e Cochrane Library em outubro de 2018, selecionando os estudos segundo a estratégia PICO de pesquisa. Dos 398 artigos encontrados, 19 atenderam os critérios de elegibilidade. Após a análise, demonstrou-se que as dietas restritas em carboidratos favorecem o controle glicêmico, melhora do perfil lipídico e redução dos medicamentos para DM2 em relação às outras opções dietéticas, no entanto, os trabalhos apresentam vieses metodológicos e são, em geral, de curto prazo. Sendo assim, é precipitado afirmar que essas dietas são mais efetivas para o tratamento do DM

Type 2 diabetes mellitus (T2DM) is considered one of the primary metabolic disorders related to the development of cardiovascular diseases and other comorbidities, with high incidence and prevalence in Brazil and in the world. Despite advances in its treatment, an increase in the number of diagnoses is estimated worldwide. In Brazil, the total number of people with the disease has grown more than 60% in 10 years. As dietary management is one of the mainstays in the treatment of T2DM, this study aimed to analyze the studies that compared carbohydrate-restricted diets with other dietary approaches to elucidate if this would be the most appropriate option for patients with T2DM. Thus, randomized clinical trials were reviewed through the PubMed and Cochrane Library research platforms in October 2018, selecting the studies according to the PICO research strategy. Of the 398 articles found, 19 met the eligibility criteria and had their data collected. After the analysis, it was demonstrated that carbohydrate-restricted diets support glycemic control, loss of body mass, improvement of lipid profile and reduction of medications for T2DM compared to other dietary options. However, a significant part of the studies has methodological biases and is generally short-term. Therefore, the level of evidence supporting dietary restriction of carbohydrates in the management of T2DM is considered moderate. Thus, according to the principle of the null hypothesis, it is unwise to affirm that these diets are superior in the treatment of DM2

Esteatosis hepática en pacientes con diabetes tipo 2 y su relación con el control glucémico / Hepatic steatosis in type 2 diabetes patients and its relationship with glycemic control

Introducción: La esteatosis hepática no alcohólica es la enfermedad con mayor frecuencia en el mundo, esta se asocia a diabetes mellitus tipo 2; padecimiento con gran impacto económico-social. Objetivo: Describir el comportamiento de esteatosis hepática en una población de pacientes con diagnóstico de diabetes mellitus tipo 2. Métodos: Se realizó un estudio observacional, descriptivo, transversal en 94 pacientes diabéticos atendidos en el Hospital Clínico Quirúrgico Hermanos Ameijeiras, en el periodo comprendido entre febrero 2016- febrero 2018. Resultados: La esteatosis fue leve en 42,6 por ciento, moderada (44,7 por ciento) y severa en 12,8 por ciento, en ambos casos, con un NAFLD score principalmente indeterminado (72,3 por ciento). Se detectó fibrosis F0-1 en 58,5 por ciento de los pacientes, F2 (29,8 por ciento) y significativa (F3 y F4) en 11,7 por ciento). Se detectó asociación entre ecogenicidad hepática aumentada, patrón hepático difuso y grado severo de esteatosis por ecografía con mayor grado de fibrosis según elastografía. Se detectó relación significativa de niveles elevados de HBA1C con fibrosis significativa medida tanto por NAFLD score como por elastografía. Conclusiones: La esteatosis hepática presente en los pacientes con diabetes mellitus fue principalmente leve a moderada con prevalencia de fibrosis leve, el grado de fibrosis significativa se asoció con ecogenicidad hepática aumentada, patrón hepático difuso, grado severo de esteatosis por ecografía y niveles elevados de hemoglobina glucosilada(AU)

Introduction: Non-alcoholic liver steatosis is the most frequent disease in the world. It is associated with type 2 diabetes mellitus, representing great economic-social impact. Objective: To describe the behavior of hepatic steatosis in a population of patients diagnosed with type 2 diabetes mellitus. Methods: An observational, descriptive, cross-sectional study was conducted in 94 diabetic patients treated at Hermanos Ameijeiras Clinical Surgical Hospital, from February 2016 to February 2018. Results: Steatosis was mild in 42.6 percent, moderate (44.7 percent) and severe in 12.8 percent, with a mainly indeterminate NAFLD score (72.3 percent). F0-1 fibrosis was detected in 58.5 percent of the patients, F2 (29.8 percent) and significant (F3 and F4) in 11.7 percent).

Significant relationship of elevated levels of HBA1C with significant fibrosis was detected, measured both by NAFLD score and by elastography. Conclusions: Hepatic steatosis present in patients with diabetes mellitus was mainly mild to moderate with prevalence of mild fibrosis, the degree of significant fibrosis was associated with increased liver echogenicity, diffuse liver pattern, severe degree of steatosis by ultrasound and high levels of hemoglobin. glycosylated(AU)

Daily intake of a bean-fiber fortified bar reduces oxidative stress

as been proposed that the consumption of common beans (Phaseolus vulgaris L.) reduces cardiovascular risk, and prevents and controls both chronic and degenerative diseases. The aim of this study was to compare the antioxidant capacity of a bean-fiber fortified bar (BFB) versus a commercial bar (CB) in 60 Mexican men and women (18-65 years old), who were randomly distributed in two groups: BFB or CB; individuals consumed a bar a day for one month. Anthropometric data, food intake and blood samples were collected. Glucose tolerance (GTT), lipid profile (PL), and lipid peroxidation (TBARS) tests were performed; carbonyls groups in serum oxidized proteins were also measured. GTT and PL were not different between both groups in either the 15 or 30-day follow-up of bar consumption assessments. There were no significant differences in either TBARS or carbonyl concentration between groups; BFB group showed higher levels of serum lipid peroxidation in basal and fifteen days measurements; these levels decreased at the final evaluation: No differences were detected on carbonyl levels between groups. In conclusion, 30 days of fiber bean bar consumption did not alter glucose or PL levels, while, in the BFF group, oxidative stress decreased within 30 days of the consumption of the fortified bar(AU)

Se ha propuesto que el consumo de frijol común (Phaseolus vulgaris L.) reduce el riesgo cardiovascular, y previene y controla las enfermedades crónicas y degenerativas. El objetivo del presente estudio fue comparar la capacidad antioxidante de una barra fortificada con fibra de frijol (BFB) versus una barra comercial (CB) en 60 hombres y mujeres mexicanos (18-65 años de edad), quienes aleatoriamente fueron distribuidos en dos grupos: El grupo BFB y el CB que consumieron la barras fortificada con frijol y la barra comercial, respectivamente, durante un mes. Se recopilaron datos antropométricos, ingesta de alimentos y muestras de sangre. Se realizó prueba de tolerancia a la glucosa (GTT), el perfil de lípidos (PL), la peroxidación de lípidos (TBARS) y la cuantificación de carbonilos en proteínas oxidadas como pruebas de bioquímica sanguínea. GTT y PL no fueron diferentes entre ambos grupos en la evaluación de seguimiento de 15 y 30 días del consumo de la barra. No hubo diferencias significativas en los TBARS o la concentración de carbonilo entre los grupos, el grupo BFB mostró niveles más altos de peroxidación de lípidos en suero en la fase basal y a los quince días del consumo de la barra; curiosamente, estos niveles disminuyeron en la evaluación final. No se detectaron diferencias en los niveles de carbonilo entre los grupos. En conclusión, 30 días de consumo de barras de fibra de frijol no alteraron los niveles de glucosa o PL; mientras que, en el grupo BFB, el estrés oxidativo disminuyó a los 30 días del consumo de la barra fortificada(AU)
