Índice leucoglucémico como predictor de complicaciones en el infarto de miocardio: registro RECUIMA / Leuko-glycemic index as a predictor of complications in myocardial infarction: RECUIMA registry

Resumen Introducción: La evaluación sinérgica de la hiperglucemia y el leucograma, como índice leucoglucémico (ILG), se asocia a un mayor número de eventos adversos durante el internamiento en pacientes con infarto agudo de miocardio con elevación del ST (IAMCEST). Objetivo: Evaluar el valor predictivo del índice leucoglucémico (ILG) en la aparición de complicaciones intrahospitalarias en el infarto agudo de miocardio con elevación del segmento ST (IAMCEST). Materiales y método: Estudio multicéntrico, observacional analítico, de cohorte histórica, que incluyó a 1.133 pacientes insertados en el Registro Cubano de Infarto del Miocardio Agudo entre enero de 2018 y junio de 2021. Los pacientes fueron divididos en cuartiles y en grupos de acuerdo con el punto de corte calculado para el ILG. Resultados: El punto de corte óptimo del ILG para predecir complicaciones fue de 1188.4 (sensibilidad 61.4%; especificidad 57.3%; área bajo la curva 0.609; p < 0.001). La aparición de complicaciones intrahospitalarias se incrementó de manera significativa en los cuartiles del ILG, así como en los dos grupos de acuerdo con el punto de corte. El análisis de regresión logística reveló que el ILG era un predictor independiente de complicaciones intrahospitalarias (OR [IC 95%] = 1.27 [1.11-1.46]; p = 0.001). Al asociar el ILG al modelo multivariado se elevó su capacidad predictiva (área bajo la curva 0.813; p < 0.001). Las curvas de Kaplan-Meier mostraron diferencias significativas entre los grupos de pacientes (p = 0.030). Conclusiones: El ILG constituye un predictor independiente de aparición de complicaciones intrahospitalarias en el IAMCEST. La adición del ILG a un modelo basal de riesgo tiene un fuerte efecto positivo en la predicción de pronósticos adversos en pacientes con diagnóstico de IAMCEST.

Abstract Introduction: The synergetic evaluation of the hyperglycemia and the white blood count as leukoglycemic index (LGI) joins a bigger number of adverse events during the internment in patients with ST Elevation Myocardial Infarction (STEMI). Objective: To evaluate the predictive value of the leukoglycemic index (LGI) in the appearing of in-hospital complications in ST-elevation myocardial infarction (STEMI). Method: Multicentral and historic cohort study, which included 1133 patients inserted in the Cuban Registry of Acute Myocardial Infarction, among January 2018 and June 2021. Patients were divided in quartiles and in groups according to the optimal cut-point calculated for the LGI. Results: Optimal cut-point of the ILG to predict complications was 1188.4 (sensibility 61.4%; specificity 57.3%; area under curve 0.609; p < 0.001). The appearing of in-hospital complications was significantly increased in the LGI’s quartiles; as well as in the two groups according to cut-point. The analysis of logistic regression revealed that the LGI was an independent predictor of in-hospital complications (OR [IC 95%] = 1.27 [1.11-1.46]; p = 0.001). When the LGI was associated to the multivariate model, its predictive capability was rose (area under curve 0.813; p < 0.001). Kaplan Meier’s curves showed significant differences among groups of patient (p = 0.030). Conclusions: The LGI is an independent predictor of appearing of in-hospital complications in STEMI. The addition of the LGI to a basal model of risk has a strong positive effect in the prediction of adverse prognosis in patients with STEMI.

Effects of liquid extract from Plinia cauliflora fruits residues on Chinese hamsters biochemical parameters / Efeitos do extrato líquido de resíduos de frutos de Plinia cauliflora sobre os parâmetros bioquímicos de hamsters chineses

Plinia cauliflora (Mart.) Kausel, popularly known as jabuticaba, is rich in polyphenols. Phenolic compounds exhibit several biological properties, which reflect on biomarkers such as biochemical parameters. In the present study, we evaluated the plasmatic levels of glucose, total cholesterol, HDL-cholesterol, triglycerides, and uric acid of Chinese hamsters fed for 45 days with a regular diet or cholesterol-enriched diet supplemented with a liquid extract obtained from P. cauliflora fruits residues standardized in ellagic acid and total phenolic compounds. The results showed that the concentrated extract obtained from jabuticaba residues increased the glycemia of animals fed with a regular diet and reduced the plasmatic uric acid levels of animals fed with a cholesterol-enriched diet. Since hyperuricemia is considered to be a significant risk factor of metabolic disorders and the principal pathological basis of gout, the liquid extract from P. cauliflora fruits residues would be a promising candidate as a novel hypouricaemic agent for further investigation.

Association of salivary alpha-2-macroglobulin with glycemia and glycated hemoglobin in type 2 diabetes mellitus: a systematic review and meta-analysis study

Abstract BACKGROUND: Chronically elevated alpha-2-macroglobulin (A2MG) in the blood has been correlated with diabetes and the HbA1c profile; however, no systematic review has been conducted to evaluate the association of A2MG salivary levels and glycemia or HbA1c levels in diabetes mellitus type 2 (DM2) patients. OBJECTIVE: To evaluate whether A2MG salivary levels are related to the glycemia or HbA1c levels in DM2 patients. DESIGN AND SETTING: Systematic review developed at Universidade Federal de Uberlândia (UFU), Brazil. METHODS: Eight databases were used as research sources. The eligibility criteria included studies that reported data regarding mean salivary A2MG and the correlation between glycemia and/or HbA1c levels of DM2 subjects (uncontrolled and well-controlled) and non-diabetic subjects. The risk of bias of the studies selected was assessed using the Joanna Briggs Institute (JBI) critical appraisal tools for use in JBI systematic reviews. Pooled correlation coefficients were estimated using the Hunter-Schmidt method. Study estimates were weighted according to their sample size, and heterogeneity was calculated using the chi-square statistic. RESULTS: Four studies on DM2 patients were included in this systematic review after careful analysis of 1482 studies. Three studies compared A2MG with HbA1c and glycemia. Overall, the correlation between A2MG and HbA1c was strong (r = 0.838). In contrast, the correlation between A2MG and glycemia was low (r = 0.354). CONCLUSION: The strong association between HbA1C and salivary A2MG suggests that this salivary protein has the potential to be a surrogate for HbA1C, if corroboratory further evidence is obtained through large-scale studies.

Introdução: A hiperglicemia pode estar presente em até 38% dos pacientes hospitalizados.O controle glicêmico está associado a melhores desfechos clínicos. Objetivo: avaliar o comportamento da variabilidade glicêmica em pacientes hospitalizados com Diabetes Mellitus 2. Metodologia: Estudo transversal, composto por pacientes hospi-talizados com e sem diabetes, adultos e idosos, de ambos os gêneros, em terapia nutricional enteral. As glicemias foram medidas por testes de glicemia capilar e classificadas como normoglicemia, hiperglicemia e variabilidade glicêmica, avaliados a partir do desvio-padrão glicêmico e coeficiente de variação glicêmico. Foram avaliados dados bioquímicos como Proteína C-reativa. A análise de variância de duas vias (ANOVA) foi utilizada para comparar os grupos, além da correlação de Spearman. Resultados: Participaram 85 indivíduos, com diabetes mellitus 2 (20%; n= 17), e sem diabetes mellitus (80%; n = 68), sendo 34% (n = 29) adultos e 66% (n=56) idosos. Adultos e idosos com diabetes mellitus apresentaram hiperglicemia em relação aos pacientes não diabéticos (p<0,01), valores supe-riores de desvio-padrão glicêmico (p<0,01) e coeficiente de variação glicêmica em relação aos pacientes sem dia-betes (p= 0,03), no entanto, não foram classificados com variabilidade glicêmica. Os valores da Proteína C-reativa foram correlacionados com o desvio-padrão glicêmico (R= 0,29; p= 0,0065), no entanto, a quantidade de carboi-dratos infundida na dieta enteral não se correlacionou estatisticamente com as glicemias nem com a variabilidade glicêmica dos pacientes (p>0,05).

Introduction: Hyperglycemia may be present in up to 38% of hospitalized patients. Glycemic control is associated with better clinical outcomes. Objective: assess the behavior of glycemic variability in hospitalized patients with Diabetes Mellitus 2. Methodology: Cross-sectional study composed of hospitalized patients with and without diabetes, adults and elderly, of both genders, undergoing enteral nutritional therapy. Blood glucose was measured by capillary blood glucose tests and classified as normoglycemia, hyperglycemia, and glycemic variability, assessed from the glycemic standard deviation and glycemic variation coefficient. Biochemical data such as C-reactive protein were assessed. Two-way analysis of variance (ANOVA) was used to compare the groups, in addition to Spearman's correlation. Results: Eighty-five individuals with diabetes mellitus 2 (20%; n=17) and without diabetes mellitus (80%; n=68) participated in the study; 34% (n=29) were adults, and 66% (n=56) were elderly. Adults and elderly people with diabetes mellitus presented hyperglycemia concerning non-diabetic patients (p<0.01), higher values of glycemic standard deviation (p<0.01), and glycemic variation coefficient concerning patients without diabetes (p= 0.03); however, they were not classified with glycemic variability. The C-reactive protein values were correlated with the glycemic standard deviation (R= 0.29; p= 0.0065); however, the amount of carbohydrates infused in the enteral diet was not statistically correlated with glycemia or with the glycemic variability of patients (p>0.05). Conclusion: hospitalized patients with or without diabetes mellitus 2 did not show glycemic variability, demonstrating glycemic control during hospitalization. (AU)

Características farmacológicas y clínicas de insulina aspártica más rápida (Fiasp®) / Pharmacological and clinical characteristics of Insulin Faster Aspart (Fiasp®)

Resumen La insulina aspártica de acción rápida es una formulación más rápida de la insulina aspártica convencional, a la que se adicionan nicotinamida y L-arginina para lograr una absorción más rápida en el tejido celular subcutáneo. Estudios farmacocinéticos y farmacodinámicos demostraron un desplazamiento de las curvas de concentración sérica de insulina/tiempo hacia la izquierda en comparación con la formulación conven cional. Su perfil de eficacia se destaca en términos del control de la glucemia posprandial temprana. Además, la insulina aspártica de acción rápida aporta flexibilidad al tratamiento, ya que puede aplicarse al momento de la comida, inmediatamente antes o hasta 20 minutos después, lo que constituye una ventaja en cuanto a calidad de vida en los pacientes con diabetes en tratamiento con insulina prandial, especialmente en poblaciones como los niños, las embarazadas o los ancianos. El patrón de seguridad y tolerabilidad es comparable al de la insulina aspártica convencional.

Abstract Fast acting aspart insulin is a faster-acting formulation of aspart insulin, having nicotinamide and L-arginine added to the molecule, in order to achieve a faster absorption through the subcutaneous cellular tissue. Pharmacokinetic and pharmacodynamic studies showed a left-shifted mean serum concentration-time profile compared to the conventional formulation. Its efficacy profile is highlighted in terms of early postprandial glycemic control. In addition, fast acting aspart insulin allows a more flexible treatment schedule, as it may be administrated at mealtime, immediately before or up to 20 minutes after; this schedule represents an advantage regarding quality of life in patients with diabetes treated with prandial insulin, especially in populations such as children, pregnant women or elderly subjects. The safety and tolerability profiles are comparable to conventional aspart insulin.

Comparación de los valores de glucosa en caninos obtenidos con glucómetros portátiles y la prueba estándar de laboratorio / Comparação dos valores de glicose em caninos obtidos com glicômetros portáteis e o teste laboratorial padrão / Comparison of glucose values in dogs obtained with portable glucometers and the standard laboratory test

La medición de glucosa en caninos es un procedimiento habitual en la clínica diaria, actualmente este valor se puede obtener mediante dispositivos portátiles y pruebas laboratoriales. Se realizó esta investigación con el fin de aportar mayor conocimiento sobre la importancia de la medición de glucosa, ya que en los últimos años ha perdido valor entre las pruebas hematológicas a considerar debido a que solo se relaciona con determinadas patologías como la diabetes u otras enfermedades metabólicas. El presente trabajo tiene como objetivo comparar los valores de glucosa en caninos obtenidos mediante un glucómetro portátil de uso humano (Accu-chek® Active, Roche Diagnostic, Mannheim, Alemania); veterinario (aLcose® Vet Glu, jjPlus Corporation, New Taipei, Taiwán) y la prueba estándar de laboratorio, esto nos indicará la fiabilidad de los resultados obtenidos mediante estos métodos. Se realizó la toma de muestras de sangre de 50 caninos clínicamente sanos, de los cuales se obtuvo el resultado de glucemia mediante estos tres métodos. Los resultados de nuestra investigación evidenciaron que las tres formas de evaluación de la glucosa sanguínea en perros brindaban resultados estadísticamente diferentes (p < 0.05). Se obtuvo valores de glucosa diferentes entre los tres métodos de medición, teniendo como promedios finales 84.14 mg/dL, 101.12 mg/dL y 91.12 mg/dL correspondientes al glucómetro portátil de uso humano, veterinario y a la prueba estándar de laboratorio respectivamente. En conclusión, los glucómetros portátiles de uso humano subestiman los valores reales de glucosa, mientras que los de uso veterinario lo sobreestiman, comparados con la prueba estándar de laboratorio.

A medição de glicose nos cães é um procedimento habitual realizado no atendimento clínico. Atualmente este valor pode ser obtido por meio de dispositivos portáteis e testes laboratoriais. Esta pesquisa foi realizada com a finalidade de destacar a importância da medição de glicose, visto que nos últimos anos esta avaliação não tem sido muito valorada entre os testes hematológicos, sendo considerada relevante apenas em relação a patologias como a diabetes e outras doenças metabólicas. O presente estudo teve como objetivo comparar os valores de glicose em cães obtidos com glicômetro portátil de uso humano; veterinário e o teste padrão de laboratório. Esta comparação poderá indicar a confiabilidade dos resultados obtidos mediante os métodos avaliados. Foi realizada a amostragem do sangue de 50 caninos clinicamente sadios os quais foram submetidos a avaliação de glicose mediante os três métodos. Os resultados de nossa investigação evidenciaram que as três formas de avaliação da glicose sanguínea têm resultados estatisticamente diferentes (p < 0,05). Os valores de glicose tiveram medias finais de 84,14 mg/dL, 101,12 mg/dL e 91,12 mg/dL para o glicômetro portátil de uso humano (Accu-chek® Active, Roche Diagnostic, Mannheim, Alemanha), veterinário (aLcose® Vet Glu, jjPlus Corporation, Nova Taipei, Taiwan) e o teste padrão de laboratório, respectivamente. Ao concluir, os glicômetros portáteis de uso humano subestimam os valores reais de glicose e os de uso veterinário os superestimam quando comparados com o teste padrão de laboratório.

The measurement of glucose in canines is a common procedure in daily clinical practice. Currently this value can be obtained by use of portable devices and laboratory tests. This research was carried out in order to provide more knowledge about the importance of glucose measurement, since in recent years it has lost value among the hematological tests to be considered because it is only related to certain pathologies such as diabetes or other metabolic diseases. The present study aimed to compare the glucose values in dogs obtained with a portable glucometer for human use, veterinarian use, and the standard laboratory test. This comparison may indicate the reliability of the results obtained through the evaluated methods. A blood sampling of 50 clinically healthy canines was taken and submitted to glucose evaluation using the three methods. Our investigation showed that the three ways of assessing blood glucose have statistically different results (p < 0.05). Glucose values had final averages of 84.14 mg/dL, 101.12 mg/dL, and 91.12 mg/dL for the portable glucometer for human use (Accu-chek® Active, Roche Diagnostic, Mannheim, Germany), veterinary (aLcose® Vet Glu, jjPlus Corporation, New Taipei, Taiwan) and the standard laboratory test, respectively. In conclusion, portable glucometers for human use underestimate the glucose values, and those for veterinary use overestimate them compared to the standard laboratory test.

The effects of macronutrients composition on hormones and substrates during a meal tolerance test in drug-naive and sitagliptin-treated individuals with type 2 diabetes: a randomized crossover study

ABSTRACT Objectives: To evaluate the effect of sitagliptin treatment in early type 2 diabetes mellitus (T2DM) and the impact of different macronutrient compositions on hormones and substrates during meal tolerance tests (MTT). Materials and methods: Half of the drug-naive patients with T2DM were randomly assigned for treatment with 100 mg of sitagliptin, q.d., or placebo for 4 weeks and then submitted to 3 consecutive MTT intercalated every 48 h. The MTTs differed in terms of macronutrient composition, with 70% of total energy from carbohydrates, proteins, or lipids. After 4 weeks of washout, a crossover treatment design was repeated. Both patients and researchers were blinded, and a repeated-measures ANOVA was employed for statistical analysis. Results: Sitagliptin treatment reduced but did not normalize fasting and post-meal glucose values in the three MTTs, with lowered area-under-glucose-curve values varying from 7% to 15%. The sitagliptin treatment also improved the insulinogenic index (+86%) and the insulin/glucose (+25%), glucagon-like peptide-1/glucose (+46%) incremental area under the curves. Patients with early T2DM maintained the lowest glucose excursion after a protein- or lipid-rich meal without any major change in insulin, C-peptide, glucagon, or NEFA levels. Conclusion: We conclude that sitagliptin treatment is tolerable and contributes to better control of glucose homeostasis in early T2DM, irrespective of macronutrient composition. The blood glucose excursion during meal ingestion is minimal in protein- or fat-rich meals, which can be a positive ally for the management of T2DM. Clinical trial no: NCT00881543

Impacto del índice triglicéridos-glucemia en la mortalidad intrahospitalaria por infarto agudo del miocardio. Resultados del registro multicéntrico RECUIMA / Triglycerides-glucose index impact on in-hospital mortality in acute myocardial infarction. Results from the RECUIMA multicenter registry

Resumen Introducción: El índice triglicéridos-glucemia (ITG/G) es considerado un nuevo marcador de resistencia a la insulina y está relacionado con el desarrollo de enfermedades cardiovasculares. Objetivo: Evaluar la capacidad del ITG/G para predecir mortalidad intrahospitalaria en los pacientes con infarto agudo del miocardio con elevación del segmento ST. Métodos: Estudio multicéntrico de cohorte que incluyó a 1123 pacientes del Registro Cubano de Infarto del Miocardio Agudo entre enero de 2018 y junio de 2021. Resultados: El punto de corte óptimo del ITG/G para predecir mortalidad fue 8.96 (sensibilidad de 65.2 %, especificidad de 62.0 % y área bajo la curva de 0.636; p < 0.001). La mortalidad intrahospitalaria se incrementó significativamente en el grupo con ITG/G ≥ 8.96. El análisis de regresión logística reveló que el ITG/G fue un marcador predictor independiente de mortalidad (RM = 2.959, IC 95 % = 1.457-6.010, p = 0.003). El modelo multivariado que incluyó el ITG/G elevó su capacidad predictiva (área bajo la curva de 0.917, p < 0.001). Las curvas de Kaplan-Meier mostraron diferencias significativas entre los grupos de pacientes (p < 0.001). Conclusiones: El ITG/G constituye un factor de riesgo independiente de mortalidad intrahospitalaria por infarto agudo del miocardio con elevación del segmento ST.

Abstract Introduction: The triglycerides-glucose (TyG) index is considered a new marker of insulin resistance, and is associated with the development of cardiovascular diseases. Objective: To evaluate the capability of TyG index to predict in-hospital mortality in patients with acute ST-elevation myocardial infarction. Methods: Multicenter cohort study that enrolled 1123 patients included in the Cuban Registry of Acute Myocardial Infarction between January 2018 and June 2021. Results: TyG index optimal cutoff point to predict mortality was 8.96 (sensitivity, 65.2%; specificity, 62.0%; area under the curve; 0.636; p < 0.001). In-hospital mortality was significantly higher in the group with TyG index ≥ 8.96. The logistic regression analysis revealed that the TyG index was an independent mortality predictor (OR = 2.959; 95% CI = 1.457-6.010; p = 0.003). When the TyG index was included in the multivariate model, it increased its predictive capacity (area under the curve, 0.917, p < 0.001). Kaplan-Meier curves showed significant differences between patient groups (p < 0.001). Conclusions: The TyG index constitutes an independent risk factor of in-hospital mortality in patients with acute ST-elevation myocardial infarction.

Dynamic circadian fluctuations of glycemia in patients with type 2 diabetes mellitus

BACKGROUND: Diabetes mellitus (DM) has glucose variability that is of such relevance that the appearance of vascular complications in patients with DM has been attributed to hyperglycemic and dysglycemic events. It is known that T1D patients mainly have glycemic variability with a specific oscillatory pattern with specific circadian characteristics for each patient. However, it has not yet been determined whether an oscillation pattern represents the variability of glycemic in T2D. This is why our objective is to determine the characteristics of glycemic oscillations in T2D and generate a robust predictive model. RESULTS: Showed that glycosylated hemoglobin, glycemia, and body mass index were all higher in patients with T2D than in controls (all p < 0.05). In addition, time in hyperglycemia and euglycemia was markedly higher and lower in the T2D group (p < 0.05), without significant differences for time in hypoglycemia. Standard deviation, coefficient of variation, and total power of glycemia were significantly higher in the T2D group than Control group (all p < 0.05). The oscillatory patterns were significantly different between groups (p = 0.032): the control group was mainly distributed at 2-3 and 6 days, whereas the T2D group showed a more homogeneous distribution across 2-3-to-6 days. CONCLUSIONS: The predictive model of glycemia showed that it is possible to accurately predict hyper- and hypo-glycemia events. Thus, T2D patients exhibit specific oscillatory patterns of glycemic control, which are possible to predict. These findings may help to improve the treatment of DM by considering the individual oscillatory patterns of patients.

Análisis comparativo de respuesta glicémica y de péptido C, tras la ingesta de estevia y D-tagatosa, según habitualidad de consumo de edulcorantes no nutritivos y preferencias alimentarias reportadas por mujeres con resistencia a la insulina / Comparative analysis of glicemic response and c peptide, after comsumption of stevia and d tagatosa, according to regular compsumtion of not nutritive sweeteners andnourish preferences reported by woman with insuline resistance

INTRODUCCIÓN: El consumo de edulcorantes no nutritivos (ENN) ha ido en aumento. A pesar de ello, se desconoce el efecto entre el consumo habitual de ENN y las preferencias alimentarias con parámetros bioquímicos en pacientes con resistencia a la insulina. OBJETIVO: Comparar la respuesta glicémica y de péptido C, según habitualidad de consumo de edulcorantes y preferencias alimentarias reportados por mujeres con resistencia a la insulina tras la ingesta de estevia y D-tagatosa. MÉTODOS: Treinta y tres mujeres con RI se sometieron a una encuesta de opción múltiple sobre preferencias alimentarias y ETCC modificada de edulcorantes. Aleatoriamente recibieron una precarga de control o experimental (estevia y D-tagatosa) donde se midió glicemia y péptido C en los tiempos -10, 30, 60, 90, 120, 180. RESULTADOS: Se encontró un ABC de péptido C más alto después de la ingesta de D-tagatosa (p = 0,02) en pacientes que prefieren alimentos ricos en proteínas en comparación con aquellos que prefieren alimentos ricos en grasas o en carbohidratos simples. Se observó un mayor ABC de péptido C (p = 0,04) para la prueba control en quienes prefieren el sabor salado y consumen menor cantidad de ENN, sin diferencias significativas entre quienes prefirieron sabor dulce. CONCLUSIONES: Al comparar las respuestas glicémicas e insulinémicas entre habitualidad de consumo de edulcorantes y preferencias alimentarias reportados por las pacientes tras la ingesta de agua, estevia y D-Tagatosa, no se obtuvieron diferencias significativas. Salvo en quienes preferían alimentos ricos en proteínas tras la ingesta de D- tagatosa y quienes preferían sabor salado con menor consumo habitual de ENN tras ingesta control.

INTRODUCTION: The consumption of non-nutritive sweeteners (NNS) has been increasing. Despite this, the effect between the habitual consumption of ENN and food preferences with biochemical parameters in patients with insulin resistance is unknown. OBJECTIVE: To compare the glycemic and C-peptide response, according to the habitual consumption of sweeteners and food preferences reported by women with insulin resistance after ingesting stevia and D-tagatose. METHODS: Thirty-three women with IR underwent a multiple choice survey on food preferences and modified ETCC for sweeteners. They randomly received a control or experimental preload (stevia and D-tagatose) where glycemia and peptide C were measured at times -10, 30, 60, 90, 120, 180. RESULTS: A higher C-peptide AUC was found after ingestion of D-tagatose (p = 0.02) in patients who prefer foods rich in protein compared to those who prefer foods rich in fat or simple carbohydrates. A higher AUC of peptide C (p = 0.04) is performed for the control test in those who prefer a salty taste and consume a lower amount of ENN, without significant differences between those who prefer a sweet taste. CONCLUSION: When comparing the glycerol and insulin responses between the habitual consumption of sweeteners and the food preferences reported by the patients after the ingestion of water, stevia and D-Tagatose, no significant differences were obtained. Except in those who prefer foods rich in protein after ingesting D-tagatose and those who prefer salty taste with less habitual consumption of NNS after control intake.

A haplotype in the dipeptidyl peptidase 4 gene impacts glycemic-related traits of Brazilian older adults

Dipeptidyl peptidase 4 (DPP4) regulates various physiological pathways and has a pivotal role in glucose homeostasis. The objective of this study was to verify the association of a haplotype constituted by two single nucleotide polymorphisms (rs2268894 and rs6741949) in the DPP4 gene with type 2 diabetes mellitus (T2DM) and fasting glycemia-related variables in a sample of Brazilian older adults, taking serum levels and enzymatic activity of DPP4 into account. Clinical, biochemical, and anthropometric characteristics as well as DPP4 serum levels and enzymatic activity were determined in 800 elderly (≥60 years old) individuals. Assessment of polymorphic sites was performed by real-time PCR whereas haplotypes were inferred from genotypic frequencies. Statistical analyses compared measures and proportions according to T2DM diagnosis and DPP4 haplotypic groups. The most common haplotype consisted of the T-rs2268894/G-rs6741949 string, which was 20% more frequent among non-diabetics. Considering non-diabetic patients alone, carriers of the T/G haplotype had significantly lower levels of blood glucose, insulin, HOMA-IR index, and DPP4 activity. Among diabetic patients, the T/G haplotype was associated with lower DPP4 levels whereas glycemic scores were not affected by allelic variants. Our results suggested that the genetic architecture of DPP4 affects the glycemic profile and DPP4 serum levels and activity among elderly individuals according to the presence or absence of T2DM, with a possible implication of the T/G haplotype to the risk of T2DM onset.

Glycemic safety of a maximum aerobic test in type 1 diabetics and their correlation with health parameters / Segurança glicêmica de um teste aeróbico máximo em pessoas com diabetes tipo 1 e sua correlação com parâmetros de saúde

To verify the glycemic safety of a maximal cardiorespiratory test (V̇ O2max) in T1DM patients and correlate the maximum cardiorespiratory values with metabolic control parameters such as glycemia, glycated hemoglobin, time of diagnosis (TD), and fat (body [GC] and visceral [GV]). The cross-sectional study evaluated ten T1DM patients (age 24.9 ± 7.5 years; time of diagnosis 11.5 ± 7.4; body mass index 22 ± 2 kg/m2 ). Metabolic glycemic control variables (before and after), glycated hemoglobin (HbA1c), time since diagnosis and total and visceral fat were collected. The CENESP maximum test protocol was used on the treadmill with direct maximal oxygen uptake (V̇ O2max). Normality test, paired t-test and correlations (p <0.05) were performed. In the results, blood glucose pre 189 ± 67 mg/dL vs. post 172 ± 66 mg/dL (p = 0.140). The V̇ O2max with a regular average score for men and women (37.4 ± 6.6 ml.kg.min-1). There was a negative and almost perfect correlation with TD, GC and GV (p = 0.028, p <0.000, and p <0.000). We conclude that is possible to perform a CENESP maximal with glycemic safe in T1DM. However, TD, GC, and GV negatively interfere with cardiorespiratory fitness and should be verified before the test. (AU)

Verificar a segurança glicêmica de um teste cardiorrespiratório máximo (V̇ O2max) em pacientes com diabetes mellitus tipo 1 (DM1) e correlacionar os valores com parâmetros de controle metabólico como glicemia, hemoglobina glicada, tempo de diagnóstico (DT) e gordura (corporal[GC] e visceral[GV]). O estudo transversal avaliou dez DM1 (idade 24,9 ± 7,5 anos; tempo de diagnóstico 11,5 ± 7,4; índice de massa corporal 22 ± 2 kg/m2). Foram coletadas variáveis de controle glicêmico metabólico (antes e depois), hemoglobina glicada (HbA1c), tempo de diagnóstico e gordura total e visceral. O protocolo de teste máximo do CENESP foi utilizado na esteira com consumo máximo direto de oxigênio (V̇ O2max). Teste de normalidade, teste t pareado e correlações (p<0,05) foram realizados. Nos resultados, glicemia pré 189 ± 67 mg/dL vs. pós 172 ± 66 mg/dL (p = 0,140). O V̇ O2max com pontuação média regular para homens e mulheres (37,4 ± 6,6 ml.kg.min-1). Houve correlação negativa e quase perfeita com DT, GC e GV (p = 0,028; p < 0,000 e p < 0,000). Concluímos que é possível realizar um CENESP máximo com segurança glicêmica no DM1. No entanto, DT, GC e GV interferem negativamente na aptidão cardiorrespiratória e devem ser verificados antes do teste.

Glycoinsulinemic parameters associated with vitamin D status in patients with chronic kidney disease undergoing dialysis therapy

ABSTRACT Evidence indicates that the physiological role of vitamin D goes beyond regulating classical domains of minerals and hormones. It is reported that the low status of Vitamin D may contribute to the occurrence of metabolic disorders, with emphasis on insulin resistance, atherosclerotic events and metabolic syndrome. In this sense, this study aimed to verify the association between metabolic and anthropometric parameters and vitamin D status in patients with chronic kidney disease undergoing hemodialysis. This was a cross-sectional study conducted with 95 patients with chronic kidney disease treated at clinics in Teresina, Piaui, Brazil. Lipid and inflammatory profile, glycemia, insulin and vitamin D status were determined. Data were analyzed using STATA software, adopting significance level of p<0.05. The results pointed to a significant association between vitamin D concentrations and adiposity of patients. It was observed that the high blood glucose and HOMA-IR values presented statistical association with vitamin D concentrations, and conditioned greater chances of their inadequacy. There was no correlation between nutrient concentrations and cytokines evaluated in the study. Therefore, it was concluded that the increase in levels of glycoinsulinemic parameters (insulin and HOMA-IR) seems to influence vitamin D status in patients with chronic kidney disease.

RESUMEN La evidencia indica que el papel fisiológico de la vitamina D va más allá de regular los dominios clásicos del eje mineral y hormonal. Hay trabajos que muestran que el bajo nivel de vitamina D puede contribuir a la aparición de trastornos metabólicos, con énfasis en la resistencia a la insulina, eventos ateroscleróticos y síndrome metabólico. En este sentido, el objetivo de este estudio fue verificar la asociación entre parámetros metabólicos y antropométricos y el estado de vitamina D en pacientes renales crónicos en hemodiálisis. Se trata de un estudio transversal realizado con 95 pacientes con enfermedad renal crónica atendidos en consultas externas de Teresina, Piauí, Brasil. Se determinó el perfil lipídico e inflamatorio, la glicemia, la insulina y el estado de vitamina D. Los datos se analizaron utilizando programa STATA , con un nivel de significancia de p<0,05. Los resultados apuntaron a una asociación significativa entre las concentraciones de vitamina D y la adiposidad de los pacientes. Se observó que los valores elevados de glucosa en sangre y HOMA-IR se asociaron estadísticamente con las concentraciones de vitamina D y condicionaron mayores posibilidades de su insuficiencia. No hubo correlación entre las concentraciones de nutrientes y las citocinas evaluadas en el estudio. Por tanto, se concluyó que el aumento de los niveles de parámetros glucoinsulinémicos (insulina y HOMA-IR) parece influir en el estado de la vitamina D en pacientes con enfermedad renal crónica.

Adverse Pregnancy Outcomes Are Associated With Lower Cut-offs for Maternal Hyperglycemia in Malaysian Women: A Retrospective Cohort Study

@#Introduction: This cohort aimed to determine glycemia distribution of pregnant women and maternal glycemia categories and its correlation with adverse pregnancy outcomes among Malaysian women. Methods: A retrospective cohort study of normal glycemia pregnant women. Binary logistic regression was used to examine the associations between maternal glycemia categories and adverse outcomes. Results: Women with elevated fasting plasma glucose (FPG) were at lower risk of having SGA infants (aORFPG 4= 0.64, 95% CI= 0.47 – 0.85; aORFPG 6= 0.68, 95% CI= 0.43–0.98; aORFPG 7= 0.64, 95% CI= 0.42–0.96) than those women in category 1. Women in the higher 2-hour plasma glucose (2hPG) category had a nearly two-fold risk of having LBW and LGA infants. Hyperglycemia less severe than gestational diabetes mellitus (GDM) was associated with LGA (aOR= 1.22, 95% CI= 1.07 – 1.88) and caesarean delivery (aOR= 1.80, 95% CI= 1.20 – 2.69), in the meanwhile GDM was associated with caesarean delivery (aOR= 1.33, 95% CI= 1.02 –1.79). Conclusion: Cut-off points for FPG and 2hPG that relate to adverse pregnancy outcomes started at 4.9 – 5.0 mmol/l and 7.5 – 7.7 mmol/l. These cut-off points were lower than the current recommended criteria of Clinical Practice Guideline (CPG) of Malaysia for GDM diagnosis. Large-scale studies are required to identify the optimal GDM cut-off.

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)
