Efectos de Cinnamomum zeylanicum en niveles glucémicos en pacientes con diabetes tipo 2: ensayo clínico aleatorizado / Effects of Cinnamomum zeylanicum on glycemic levels in patients with type 2 diabetes: Randomized clinical trial

Objetivo: Evaluar el efecto del consumo de suplemento de Cinnamomum zeylanicum (canela) en los niveles glucémicos de adultos mexicanos con diabetes tipo 2. Métodos: Se realizó un ensayo clínico aleatorizado simple ciego con 30 pacientes >18 años con diabetes tipo 2, se aleatorizaron en los grupos: intervención y control; donde consumieron cápsulas con 2 gramos de C. zeylanicum o harina de trigo (placebo) diario por 12 semanas y se midieron variables antropométricas y bioquímicas (HbA1c, GPa, triglicéridos, colesterol total, HDL y LDL). Se utilizó el software IBM SPSS versión 23 y se aplicó la prueba T-Student y U-Mann Withney para muestras independientes (según el comportamiento de la variable) para las diferencias entre grupos, valores p<0.05 fueron considerados estadísticamente significativos. Resultados: No se observaron cambios significativos en HbA1c entre grupos (p>0.05). Sin embargo, post-tratamiento el grupo intervención disminuyó significativamente HbA1c al compararlo con su línea base (-0.41%, p=0.01) mientras que no se encontraron diferencias en el grupo control (+0.03%, p=0.64). No hubo diferencias significativas en variables antropométricas ni bioquímicas. Conclusiones: El consumo de 2 g de C. zeylanicum en mexicanos con diabetes tipo 2 no produjo cambios significativos entre grupos. Se sugieren nuevos estudios donde se evalúe el suplemento de canela con una muestra mayor. ClinicalTrials.gov; NCT04023539. (AU)

Objective: To evaluate the effect of Cinnamomum zeylanicum (cinnamon) supplement use on the glycemic levels of Mexican adults with type 2 diabetes. Methods: A single-blind randomized clinical trial was conducted with 30 patients over 18 years of age with type 2 diabetes. They were randomized into intervention and control groups where they took 2-gram capsules of Cinnamomum zeylanicum or wheat flour (placebo) daily for 12 weeks; then the anthropometric and biochemical variables HbA1c, FPG, triglycerides, total cholesterol, HDL and LDL were measured. IBM SPSS version 23 software was used and the Student's t-test and Mann-Whitney U test for independent samples (according to the behavior of the variable) were applied for differences between groups, p-values <0.05 were considered statistically significant. Results: No significant changes in HbA1c were seen between the two groups (p>0.05). However, post-treatment, the HbA1c value in the intervention group decreased significantly when compared to their baseline (-0.41%, p=0.01), while no differences were found in the control group (+0.03%, p=0.64). There were no significant differences in the anthropometric or biochemical variables. Conclusions: The consumption of 2 g of Cinnamomum zeylanicum in Mexican people with type 2 diabetes did not produce significant changes between the groups. New studies evaluating cinnamon supplementation on a larger sample size are suggested. ClinicalTrials.gov; NCT04023539. (AU)

Effects of the COVID-19 pandemic on gestational diabetes in Castilla-La Mancha (Spain).

SUBJECT-MATTER: To assess the effect of the 2019 coronavirus (COVID-19) pandemic on gestational diabetes (GDM). MATERIAL AND METHODS: In this retrospective, multicentre, non-interventional study carried out in Castilla-La Mancha, Spain, we compared 663 women with GDM exposed to the pandemic (pandemic group), with 622 women with GDM seen one year earlier (pre-pandemic group). The primary endpoint was a Large for Gestational Age (LGA) newborn as an indicator of poor GDM control. Secondary endpoints included obstetric and neonatal complications. RESULTS: During the pandemic, the gestational week at diagnosis (24.2 ±â€¯7.4 vs 22.9 ±â€¯7.7, p = 0.0016) and first visit to Endocrinology (26.6 ±â€¯7.2 vs 25.3 ±â€¯7.6, p = 0.0014) were earlier. Face-to-face consultations were maintained in most cases (80.3%). The new diagnostic criteria for GDM were used in only 3% of cases. However, in the pandemic group, the final HbA1c was higher (5.2 ±â€¯0.48 vs 5.29 ±â€¯0.44%, p = 0.047) and there were more LGA newborns (8.5% vs 12.8%, p = 0.015). There were no differences in perinatal complications. CONCLUSIONS: Care for GDM in our Public Health System did not significantly deteriorate during the COVID-19 pandemic. However, this did not prevent a higher number of LGA newborns.

Objetivo: analizar la correlación entre el tiempo en rango y la hemoglobina glicosilada de personas que viven con diabetes mellitus y realizan la monitorización continua de la glucemia o el automonitoreo de la glucemia capilar Método: revisión sistemática de etiología y riesgo basada en las directrices del JBI e informada según los Preferred Reporting Items for Systematic Reviews and Meta-Analyses, abarcando seis bases de datos y la literatura gris. La muestra incluyó 16 estudios y la calidad metodológica fue evaluada utilizando las herramientas del JBI. Protocolo registrado en Open Science Framework, disponible en https://doi.org/10.17605/OSF.IO/NKMZB. Resultados: tiempo en rango (70-180 mg/dl) mostró una correlación negativa con la hemoglobina glicosilada, mientras que el tiempo por encima del rango (>180 mg/dl) mostró una correlación positiva. Los coeficientes de correlación variaron entre -0,310 y -0,869 para el tiempo en rango, y entre 0,66 y 0,934 para el tiempo por encima del rango. Un estudio se realizó en una población que hacía el automonitoreo. Conclusión: hay una correlación estadísticamente significativa entre el tiempo en rango y el tiempo por encima del rango con la hemoglobina glicosilada. Cuanto mayor sea la proporción en el rango glucémico adecuado, más cerca o por debajo del 7% estará la hemoglobina glicosilada. Se necesitan más estudios que evalúen esta métrica con datos del automonitoreo de la glucemia.

Objective: to analyze the correlation between time on target and glycated hemoglobin in people living with diabetes mellitus and carrying out continuous blood glucose monitoring or self-monitoring of capillary blood glucose. Method: systematic review of etiology and risk based on JBI guidelines and reported according to Preferred Reporting Items for Systematic Reviews and Meta- Analyses, covering six databases and grey literature. The sample included 16 studies and methodological quality was assessed using JBI tools. Protocol registered in the Open Science Framework, available at https://doi.org/10.17605/OSF.IO/NKMZB. Results: time on target (70-180 mg/dl) showed a negative correlation with glycated hemoglobin, while time above target (>180 mg/dl) showed a positive correlation. Correlation coefficients ranged between -0.310 and -0.869 for time on target, and between 0.66 and 0.934 for time above target. A study was carried out on a population that performed self-monitoring. Conclusion: there is a statistically significant correlation between time on target and time above target with glycated hemoglobin. The higher the proportion in the adequate glycemic range, the closer to or less than 7% the glycated hemoglobin will be. More studies are needed to evaluate this metric with data from self-monitoring of blood glucose.

El control glicémico perioperatorio: principal factor en la disminución de complicaciones postoperatorias en pacientes diabéticos

La incidencia y prevalencia de la diabetes mellitus ha aumentado exponencialmente a nivel mundial en las últimas décadas. Los pacientes diabéticos presentan mayor probabilidad de sufrir graves complicaciones, en los procedimientos quirúrgicos en relación a la población general. El presente artículo tiene como objetivo, describir la repercusión del estado hiperglucémico perioperatorio en la etapa postoperatoria en pacientes diabéticos. Para el logro del objetivo planteado se realizó la consulta de diversas obras, que abarcan los resultados de investigación con diferentes modalidades relacionadas con la temática. Se pudo apreciar que la hiperglucemia perioperatoria se vincula con resultados adversos en pacientes a los que se les realiza cirugía general y que padecen diabetes mellitus, sin embargo, en los pacientes que se ha logrado control glicémico con terapia insulínica antes de la intervención, no presentaron mayor riesgo, que el que aparece en sujetos con buen control metabólico. La regulación de la glucosa en la etapa perioperatoria es un parámetro importante en el paciente diabético, que reduce considerablemente las complicaciones en los procedimientos quirúrgicos, las prolongadas estancias en las Unidades de Cuidados Intensivos, e incluso, la muerte.

The incidence and prevalence of diabetes mellitus has increased exponentially worldwide in recent decades. Diabetic patients are more likely to suffer serious complications in surgical procedures compared to the general population. The objective of this article is to describe the repercussion of the perioperative hyperglycemic state in the post-surgical stage in diabetic patients. In order to achieve the stated objective, various works were consulted, which include the results of research with different modalities related to the subject. It was possible to appreciate that perioperative hyperglycemia is associated with adverse results in general surgery patients with diabetes mellitus, however, in patients who have achieved glycemic control with insulin therapy before the intervention, they did not present a greater risk than that which appears in subjects with good metabolic control. Glucose regulation in the perioperative stage is an important parameter in diabetic patients, which considerably reduces complications in surgical procedures, long stays in Intensive Care Units, and even death.

Regional differences in the degree of glycaemic diabetes control in Spain and associated factors. IBERICAN study.

BACKGROUND AND OBJECTIVE: The prevalence of type 2 diabetes (T2D) is high, it is increasing and its degree of control seems to be improvable with important social and health consequences. The objective of this study is to determine the regional differences in the degree of glycaemic control of T2D in Spain and its associated factors. MATERIAL AND METHODS: Cross-sectional, multicentre, observational study in patients with T2D between 18 and 85 years of age selected by consecutive sampling between 2014 and 2018. The population was divided into four regions: north, centre, Mediterranean and south-east. The main variable was the value of glycated haemoglobin (HbA1c). Sociodemographic and clinical variables, presence or absence of other risk factors and treatment were recorded. RESULTS: A total of 1587 patients with T2D were analysed, with a mean age of 65.93 years (standard deviation [SD] 10.14); 54.5% were men; the mean duration of T2D was 8.63 years (SD 6.64) and the mean HbA1c value was 7.05%. Of the total, 59.8% had an HbA1c value ≤ 7% (north 59.5%, centre 59.5%, Mediterranean 60.6% and south-east 59.8%; P=.99). The factors for poor control were: in the north, duration of T2D and being sedentary; in the centre, duration of T2D and having a low income; in the Mediterranean, duration of T2D; and in the south-east, duration of T2D and having a low level of education or income. Overall, 76.2% of the subjects had hypertension, 75.1% dyslipidaemia, and 51.7% obesity, with significant differences between regions only being observed in the case of dyslipidaemia (P<.001). CONCLUSIONS: No differences were observed in the degree of diabetes control in the different regions, with the percentage of patients needing intensification in their control being high in all of them. The factors associated with poor control were the duration of the disease, a low level of education or income, and a sedentary lifestyle.

Glucometrics in the first week of critical illness and its association with mortality / Glucometría en la primera semana de enfermedad crítica y su asociación con la mortalidad

Objective Evaluation of glucometrics in the first week of ICU stay and its association with outcomes. Design Prospective observational study. Setting Mixed ICU of teaching hospital. Patients Adults initiated on insulin infusion for 2 consecutive blood glucose (BG) readings ≥180mg/dL. Main variables of interest Glucometrics calculated from the BG of first week of admission: hyperglycemia (BG>180mg/dL) and hypoglycemia (BG<70mg/dL) episodes; median, standard deviation (SD) and coefficient of variation (CV) of BG, glycemic lability index (GLI), time in target BG range (TIR). Factors influencing glucometrics and the association of glucometrics to patient outcomes analyzed. Results A total of 5762 BG measurements in 100 patients of median age 55 years included. Glucometrics: hyperglycemia: 2253 (39%), hypoglycemia: 28 (0.48%), median BG: 169mg/dL (162–178.75), SD 31mg/dL (26–38.75), CV 18.6% (17.1–22.5), GLI: 718.5 [(mg/dL)2/h]/week (540.5–1131.5) and TIR 57% (50–67). Diabetes and higher APACHE II score were associated with higher SD and CV, and lower TIR. On multivariate regression, diabetes (p=0.009) and APACHE II score (p=0.016) were independently associated with higher SD. Higher SD and CV were associated with less vasopressor-free days; lower TIR with more blood-stream infections (BSI). Patients with higher SD, CV and GLI had a higher 28-day mortality. On multivariate analysis, GLI alone was associated with a higher mortality (OR 2.99, p=0.04). Conclusions Glycemic lability in the first week in ICU patients receiving insulin infusion is associated with higher mortality. Lower TIR is associated with more blood stream infections (AU)

Objetivo Evaluación de la glucometría en la primera semana de estancia en la UCI y su asociación con los resultados. Diseño Estudio observacional prospectivo. Ámbito UCI mixta de hospital docente. Pacientes Adultos que iniciaron una infusión de insulina para dos lecturas consecutivas de glucosa en sangre (GS) ≥180mg/dl. Principales variables de interés Glucometría calculada a partir de la GS de la primera semana de ingreso: episodios de hiperglucemia (GS >180mg/dl) e hipoglucemia (GS <70mg/dl); mediana, desviación estándar (DE) y coeficiente de variación (CV) de GS, índice de labilidad glucémica (ILG), tiempo en el rango objetivo de GS (TIR). Resultados Se incluyeron un total de 5.762 GS en 100 pacientes con una mediana de edad de 55años. Glucometría: hiperglucemia: 2.253 (39%), hipoglucemia: 28 (0,48%), mediana GS: 169mg/dl, DE 31mg/dl, CV 18,6%, ILG: 718,5 [(mg/dl)2/h]/semana, TIR 57%. La diabetes y una puntuación APACHEII más alta se asociaron con una DE y un CV más altos y una TIR más baja. En la regresión multivariada, la diabetes (p=0,009) y la puntuación APACHEII (p=0,016) se asociaron de forma independiente con una DE más alta. La DE y el CV más altos se asociaron con menos días sin vasopresores; menor TIR, con más infecciones del torrente sanguíneo (ITS). En el análisis multivariado, el ILG solo se asoció con una mayor mortalidad (OR: 2,99, p=0,04). Conclusiones La labilidad glucémica en la primera semana en pacientes de UCI que reciben infusión de insulina se asocia con mayor mortalidad. Una TIR más baja se asocia con más ITS (AU)

Inadequate diabetes knowledge is associated with poor glycemia control in patients with type 2 diabetes / El conocimiento inadecuado de la diabetes se asocia con un control glucémico deficiente en pacientes con diabetes de tipo 2

Objective: To identify the association between glycemia control with level of diabetes knowledge, diabetes education, and lifestyle variables in patients with type 2 diabetes. Design: Cross-sectional analytical study. Site: Clinics of the Mexican Institute of Social Security (IMSS), Mexico. Participants: Patients with type 2 diabetes. Main measurements: Glycated hemoglobin (HbA1c), glucose, and lipid profile levels were measured from fasting venous blood samples. Assessment of disease knowledge was performed using the Diabetes Knowledge Questionnaire (DKQ-24). Systolic and diastolic blood pressure was measured. Weight and abdominal circumference were measured, as well as body composition using bioimpedance. Sociodemographic, clinical, and lifestyle variables were obtained. Results: A total of 297 patients were included, sixty-seven percent (67%) were women with a median of six years since the diagnosis of diabetes. Only 7% of patients had adequate diabetes knowledge, and 56% had regular knowledge. Patients with adequate diabetes knowledge had a lower body mass index (p=0.016), lower percentage of fat (p=0.008), and lower fat mass (p=0.018); followed a diet (p=0.004) and had received diabetes education (p=0.002), and to obtain information about their illness (p=0.001). Patients with low levels of diabetes knowledge had a higher risk of HbA1c≥7% (OR: 4.68; 95% CI: 1.48,14.86; p=0.009), as well as those who did not receive diabetes education (OR: 2.17; 95% CI: 1.21–3.90; p=0.009) and those who did not follow a diet (OR: 2.37; 95% CI: 1.01,5.55; p=0.046). Conclusion: Inadequate knowledge of diabetes, lack of diabetes education, and dietary adherence are associated with poor glycemia control in patients with diabetes.(AU)

Effects of lockdown by COVID-19 on glycemic control of Cuban children and adolescents with type 1 diabetes mellitus / Efectos del confinamiento por COVID-19 sobre el control glucémico de niños y adolescentes con diabetes mellitus tipo 1 / Efeitos do confinamento COVID-19 no controle glicêmico de crianças e adolescentes com diabetes mellitus tipo 1

Introduction: The purpose of this study was to determine the impact of confinement due to COVID-19 on glycemic control in children and adolescents with type 1 diabetes mellitus. Material and methods: An observational, descriptive study with a prospective design was carried out in Cuba, between November 2020 and May 2021. The sample consisted of 41 children and adolescents from a Provincial Center for Care and Education for Diabetic Patients. Anthropometric measurements (weight, height, and BMI) were obtained from the patients' medical records at the time of debut and at the time of the follow-up visit during the study period. Glycemic control was determined from the value of glycosylated hemoglobin (HbA1c). The comparison of the means between independent groups of variables was carried out using the ANOVA analysis of variance of a Kruskal-Wallis factor when quantitative variables were brought, and Pearson's Chi square in the case of categorical variables. Results: It was shown that during confinement, 78.05% of the patients had poor glycemic control. In addition, the requirements for higher total doses of insulin (p=0.005), both fast-acting (p=0.011) and slow-acting (p=0.008), and the highest dosage by weight in kilograms (p=0.003), and the highest evolution time (p=0.011) were significantly related to poor glycemic control. Most of the variables that were associated with poor glycemic control during confinement were also associated before said period. Conclusions: The confinement had a negative impact on the glycemic control of children and adolescents with type 1 diabetes mellitus in Cuba, since during this period the patients required higher doses of insulin and showed higher HbA1c figures.

Introducción: El propósito de este estudio fue determinar el impacto del confinamiento por COVID-19 en el control glucémico de niños y adolescentes con diabetes mellitus tipo 1. Material y métodos: Se realizó un estudio observacional, descriptivo con diseño prospectivo en Cuba, entre noviembre de 2020 y mayo de 2021. La muestra estuvo constituida por 41 niños y adolescentes de un Centro Provincial de Atención y Educación al Paciente Diabético. Las mediciones antropométricas (peso, talla e IMC) fueron obtenidas de las historias clínicas de los pacientes al momento del debut y al momento de la consulta de seguimiento durante el periodo del estudio. El control glucémico fue determinado a partir del valor de la hemoglobina glucosilada (HbA1c). La comparación de las medias entre grupos de variables independientes fue llevada a cabo mediante el análisis de varianza ANOVA de un factor de Kruskal-Wallis cuando se trataba de variables cuantitativas, y Chi cuadrado de Pearson en el caso de las variables categóricas. Resultados: Se observó que durante el confinamiento el 78,05 % de los pacientes presentaban un mal control glucémico. Además, los requerimientos de mayores dosis totales de insulina (p=0,005), tanto de acción rápida (p=0,011) como lenta (p=0,008), y la mayor dosificación por peso en kilogramos (p=0,003), y el mayor tiempo de evolución (p=0,011) se relacionaron significativamente con el mal control glucémico. La mayoría las variables que se asociaron a un mal control glucémico durante el confinamiento, también lo hacían antes de dicho período. Conclusiones: El confinamiento tuvo un impacto negativo sobre el control glucémico de niños y adolescentes con diabetes mellitus tipo 1 en Cuba, ya que durante este período los pacientes requirieron mayores dosis de insulina y mostraron mayores cifras de HbA1c.

Introdução: O objetivo deste estudo foi determinar o impacto do confinamento devido ao COVID-19 no controle glicêmico em crianças e adolescentes com diabetes mellitus tipo 1. Material e métodos: Estudo observacional, descritivo, com desenho prospectivo, realizado em Cuba, entre novembro de 2020 e maio de 2021. A amostra foi composta por 41 crianças e adolescentes de um Centro Provincial de Atenção e Educação para Diabéticos. As medidas antropométricas (peso, altura e IMC) foram obtidas dos prontuários dos pacientes no momento da estreia e no momento da consulta de acompanhamento durante o período do estudo. O controle glicêmico foi determinado a partir do valor da hemoglobina glicosilada (HbA1c). A comparação das médias entre grupos de variáveis ​​independentes foi realizada por meio da análise de variância ANOVA de um fator de Kruskal-Wallis no caso de variáveis ​​quantitativas e do Qui-quadrado de Pearson no caso de variáveis ​​categóricas. Resultados: Observou-se que durante o confinamento, 78,05% dos pacientes apresentaram mau controle glicêmico. Além disso, as necessidades de maiores doses totais de insulina (p=0,005), tanto de ação rápida (p=0,011) quanto de ação lenta (p=0,008), e a maior dosagem por peso em quilogramas (p=0,003), e o maior tempo de evolução (p=0,011) relacionaram-se significativamente com o mau controle glicêmico. A maioria das variáveis ​​que se associaram ao mau controle glicêmico durante o confinamento também se associaram antes desse período. Conclusões: O confinamento teve um impacto negativo no controle glicêmico de crianças e adolescentes com diabetes mellitus tipo 1 em Cuba, pois durante esse período os pacientes necessitaram de doses mais altas de insulina e apresentaram valores de HbA1c mais elevados.

Estrategias alternativas al uso de la hemoglobina glicosilada en la monitorización del estado glucémico de los pacientes diabéticos con enfermedad renal crónica terminal / Alternative strategies to the use of glycosylated hemoglobin in monitoring the glycemic status of diabetic patients with end-stage renal disease

Introducción: La diabetes mellitus (DM) es una de las principales causas de enfermedad renal crónica terminal. Un óptimo control glucémico es básico para prevenir las comorbilidades asociadas a la enfermedad, siendo la hemoglobina glicosilada (HbA1c) el marcador glucémico recomendado. No obstante, en pacientes en hemodiálisis (HD) este marcador presenta importantes limitaciones, lo que ha llevado a buscar marcadores alternativos como albúmina glicosilada (AG), fracción lábil de la hemoglobina glicosilada (LHbA1c) o índices de glicación.Pacientes y métodosSe reclutaron 47 pacientes en HD, 23 con DM, obteniéndose muestras para la determinación de AG, HbA1c y LHbA1c. Los índices de glicación, que permiten estimar el valor de HbA1c mediante glucosa, AG o LHbA1c, se calcularon incluyendo un grupo control compuesto por 75 pacientes diabéticos sin enfermedad renal.ResultadosLos pacientes diabéticos en HD presentaron valores medios significativamente mayores que los pacientes sin DM para glucosa [160 (44) vs. 96 (12) mg/dL], HbA1c [6,4 (1,0) vs. 4,9 (0,3)%], AG [16,0 (5,1) vs. 12,9 (1,6)%] y LHbA1c [2,0 (0,3) vs. 1,7 (0,2)%].La HbA1c calculada mediante los índices de glicación fue significativamente superior a la medida en todos los pacientes en HD, indistintamente del marcador empleado para su estimación.ConclusionesLos marcadores glucémicos evaluados (glucosa, AG y LHbA1c) parecen reflejar una posible subestimación del estado glucémico real por la HbA1c debido a las limitaciones que presenta en los pacientes en HD. El uso de marcadores alternativos, teniendo en cuenta también sus limitaciones, podría mejorar el seguimiento de los pacientes en HD y disminuir, por tanto, el riesgo del desarrollo de complicaciones asociadas a DM2.

Background:Diabetes mellitus (DM) is one of the leading causes of end-stage renal disease. Glycosylated hemoglobin (HbA1c) is the recommended glycemic marker to achieve an optimal glycemic control that is essential to prevent comorbidities associated with the disease. However, in patients on haemodialysis (HD) this marker has important limitations, this reason has led us to search alternative markers such as glycosylated albumin (AG), labile fraction of glycosylated hemoglobin (LHbA1c) or glycation indices.Patients and methodsWe enrolled 47 patients in HD, 23 with DM, obtaining samples for the determination of de AG, HbA1c y LHbA1c. Glycation indices, which allow estimated the HbA1c using glucose, AG or LHbA1c, were calculated including a control group composed of 75 diabetic patients without kidney disease.ResultsDiabetic patients in HD had significantly higher mean values than patients without DM for glucose [160 (44) vs 96 (12)mg/dL], HbA1c [6,4 (1,0) vs 4,9 (0,3)%], AG [16,0 (5,1) vs 12,9 (1,6)%] and LHbA1c [2,0 (0,3) vs 1,7 (0,2)%].HbA1c calculated using glycation indices was significantly higher than measured in all HD patients, regardless of the marker used for the estimation.ConclusionsThe glycemic markers evaluated (glucose, AG and LHbA1c), could reflect a possible underestimation of the real glycemic state by HbA1c because of the limitations of this marker in HD patients. The use of alternative markers, knowing their limitations, could improve the monitoring of patients on HD and, therefore, reduce the risk of developing DM2 complications. (AU)

Glucometrics in the first week of critical illness and its association with mortality.

OBJECTIVE: Evaluation of glucometrics in the first week of ICU stay and its association with outcomes. DESIGN: Prospective observational study. SETTING: Mixed ICU of teaching hospital. PATIENTS: Adults initiated on insulin infusion for 2 consecutive blood glucose (BG) readings ≥180mg/dL. MAIN VARIABLES OF INTEREST: Glucometrics calculated from the BG of first week of admission: hyperglycemia (BG>180mg/dL) and hypoglycemia (BG<70mg/dL) episodes; median, standard deviation (SD) and coefficient of variation (CV) of BG, glycemic lability index (GLI), time in target BG range (TIR). Factors influencing glucometrics and the association of glucometrics to patient outcomes analyzed. RESULTS: A total of 5762 BG measurements in 100 patients of median age 55 years included. Glucometrics: hyperglycemia: 2253 (39%), hypoglycemia: 28 (0.48%), median BG: 169mg/dL (162-178.75), SD 31mg/dL (26-38.75), CV 18.6% (17.1-22.5), GLI: 718.5 [(mg/dL)2/h]/week (540.5-1131.5) and TIR 57% (50-67). Diabetes and higher APACHE II score were associated with higher SD and CV, and lower TIR. On multivariate regression, diabetes (p=0.009) and APACHE II score (p=0.016) were independently associated with higher SD. Higher SD and CV were associated with less vasopressor-free days; lower TIR with more blood-stream infections (BSI). Patients with higher SD, CV and GLI had a higher 28-day mortality. On multivariate analysis, GLI alone was associated with a higher mortality (OR 2.99, p=0.04). CONCLUSIONS: Glycemic lability in the first week in ICU patients receiving insulin infusion is associated with higher mortality. Lower TIR is associated with more blood stream infections.

Glycemic variability and mortality in oncologic intensive care units / Variabilidade glicêmica e mortalidade em unidades de terapia intensiva oncológicas / Variabilidad glucémica y mortalidad en unidades de cuidados intensivos oncológicos

ABSTRACT Objective: This study aimed to investigate the association between glycemic variability and mortality in patients admitted to oncologic intensive care units. Methods: A retrospective cohort study was conducted using a convenience sample of 30 medical records of patients over 18 years of age of both sexes. Glycemic variability was measured using the standard deviation and general amplitude. Statistical analysis was performed using the receiver operating characteristic (ROC) curve and the area under the curve (AUC). The significance level (α) was set at 5% with a confidence interval (CI) of 95%. Results: The study included 14 male patients (46.67%) with a mean age of 60±15 years. A total of 1503 blood glucose samples were collected. The AUC analysis for the standard deviation did not show a statistically significant result (p=.966; 95% CI=[0.283, 0.726]). In contrast, the general amplitude had a statistically significant association with mortality (p=.049; 95% CI=[0.514, 0.916]). Conclusions: This study found that glycemic variability measured by the general amplitude was significantly associated with patient mortality in oncologic intensive care units. These findings suggest that monitoring glycemic variability may be an important factor in the management of critically ill patients in oncologic intensive care units.

Objetivo: analisar a produção científica acerca do conhecimento, atitude e prática de gestantes sobre o controle glicêmico. Métodos: revisão integrativa da literatura, a partir de artigos publicados no período de 2016 a 2022, nas bases de dados CINAHL, Medline e Web of Science e nas ferramentas de busca PubMed, BVS e Google Scholar. Dos 686 artigos identificados, 19 foram selecionados para compor a presente revisão. Resultados: O conhecimento das gestantes sobre controle glicêmico se mostrou satisfatório quando associado às que já sabiam do diagnóstico da doença. Os Conteúdos mais abordados nos estudos foram manejo da glicemia, efeito materno-fetal, seguimento da dieta, fatores de risco, definição da doença e tratamento. A atitude e a prática foram insatisfatórias na maioria dos achados, com preocupações centradas na incapacidade de viver uma vida normal no futuro. As principais práticas no manejo da diabetes por gestantes estão relacionadas ao uso da insulina. Conclusão: investimentos em educação em saúde sobre diabetes mellitus gestacional são essenciais para favorecer o autocuidado desde o diagnóstico até o acompanhamento pós-parto, podendo contribuir a prevenção de complicações durante o período gestacional e parto.

Objective: to analyze the scientific production about the knowledge, attitude and practice of pregnant women about glycemic control. Method: integrative review of the literature, based on articles published from 2016 to 2022, in the CINAHL, Medline and Web of Science databases and in the search engines PubMed, VHL and Google Scholar. Of the 686 articles identified, 14 were selected to make up the present review. Results: The knowledge of pregnant women about glycemic control was satisfactory when associated with those who already knew about the diagnosis of the disease. The contents most addressed in the studies were glucose management, maternal- fetal effect, diet follow-up, risk factors, disease definition and treatment. Attitude and practice were unsatisfactory in most findings, with concerns centered on the inability to live a normal life in the future. The main practices in the management of diabetes by pregnant women are related to the use of insulin. Conclusion: investments in health education on gestational diabetes mellitus are essential to favor self-care from diagnosis to postpartum follow-up, and may contribute to the prevention of complications during pregnancy and delivery.

Effect of personality on blood glucose control in patients with type 1 diabetes.

OBJECTIVE: The diagnosis of type 1 diabetes mellitus (DM1) has a major impact on young people and their families. Psychosocial factors, patient motivation, participation and acceptance of the disease are essential to achieve good blood glucose control. Our aims were to analyse personality traits and how they are related to blood glucose control in patients with DM1. METHODS: Sixty-two patients with DM1 over 18 years of age, with at least one-year disease duration and absence of advanced chronic complications were studied. Clinical, biological and personality parameters were measured. The Millon Index of Personality Styles was administered for personality assessment. RESULTS: Significant correlations between different personality variables and glycated haemoglobin (HbA1c) values were found. Individuals with poor blood glucose control had significantly higher scores on the Feeling-guided (53.6±25.7 vs 36.2±26.8, p=0.021), Innovation-seeking (36.7±24.1 vs 21.9±21.4, p=0.025), Dissenting (41.1±24.4 vs 15.6±16.6, p=0.001), Submissive (41.5±25.1 vs 28.3±14.7, p=0.038) and Dissatisfied (37.5±27.5 vs 19.5±20.2, p=0.015) scales. This psychological profile is characterised by greater focus on emotions and personal values (feeling-guided), the tendency to reject conventional ideas (innovation-seeking), an aversion to complying with norms and a preference for autonomy (unconventional/dissenting), labile self-confidence (submissive/yielding) and expressed disagreement with others (dissatisfied/complaining). Factor analysis based on the main components of the variance yielded four factors. Factor characterised as related to rebelliousness or independent judgement and action was correlated with poor blood glucose control (r=0.402, p<0.05). CONCLUSION: The rebellious or non-conformist personality type is closely associated with poor blood glucose control in patients with DM1.

Comportamento glicêmico de pacientes em pós-operatório de cirurgia cardíaca: estudo de coorte / Glycemic behavior of patients in the postoperative period of heart surgery: cohort study / Comportamiento glucémico de pacientes en postoperatorio de cirugía cardíaca: estudio de cohorte

Objetivo: comparar o comportamento glicêmico dos pacientes em pós-operatório de cirurgia cardíaca valvar e de revascularização do miocárdio, submetidos ao mesmo protocolo de controle glicêmico, e avaliar a incidência de hipoglicemia e mortalidade intra-hospitalar dessa população. Método: estudo de coorte, retrospectivo, quantitativo, que avaliou 354 prontuários de cirurgias realizadas em 2016. Resultados: pacientes revascularizados apresentaram maiores médias glicêmicas (149,14±36,03), maior uso de insulina e coeficiente de variação (23,30%). Entretanto, a incidência de hipoglicemia foi maior entre valvares (35,32%), mais acometidos por lesão renal aguda (6,58%), terapia de substituição renal (11,97%) e mortalidade hospitalar (6,58%). Conclusão: evidenciou-se uma população heterogênea com desfechos clínicos que caracterizaram os valvares como mais criticos, devido a maior número de portadores de fibrilaçao atrial, maior tempo de CEC, e maior uso de vasoaminas e corticosteroides. Logo, é necessário conhecer as particularidades de cada população, para gerenciar protocolos específicos de controle glicêmico para diferentes perfis epidemiológicos.

Objective: to compare the glycemic behavior of patients in the postoperative period of valve heart surgery and myocardial revascularization, submitted to the same glycemic control protocol and to assess the incidence of hypoglycemia and mortality and in-hospital mortality in this population. Method: cohort, retrospective, quantitative study that evaluated 354 medical records of surgeries performed in 2016. Results: revascularized patients had higher blood glucose means (149,14±36.03), greater use of insulin and higher coefficient of variation (23.30%). However, the incidence of hypoglycemia was higher (35.32%) valve patients, more affected by acute kidney injury (6.58%), renal replacement therapy (11.97%) and hospital mortality (6.58%). Conclusion: a heterogeneous population with clinical outcomes that characterized the valves as more critical, due to a greater number of patients with atrial fibrillation, longer CEC time, and greater use of vasoamines and corticosteroids. It is necessary to know the particularities of each population, in order to manage specific glycemic control protocols for different epidemiological profiles.

Objetivo: comparar el comportamiento glucémico de pacientes en postoperatorio de cirugía valvular y revascularización miocárdica, sometidos al mismo protocolo de control glicémico y evaluar la incidencia de hipoglucemia y mortalidad hospitalaria en esta población. Método: estudio de cohorte, retrospectivo, cuantitativo que evaluó 354 historias clínicas, entre agosto y octubre de 2020, de cirugías realizadas en 2016. Resultados: pacientes revascularizados presentaron mayores medias de glucemia (149,14±36,03), mayor uso de insulina y mayor coeficiente de variación (23,30%). Aunque, la incidencia de hipoglucemia fue mayor (35,32%) entre las válvulas, que se vieron más afectadas por daño renal agudo (6,58%), terapia de reemplazo renal (11,97%) y mortalidad hospitalaria (6,58%). Conclusión: el estudio mostró una población heterogénea con resultados clínicos que caracterizaron a las válvulas como más críticas, debido a un mayor número de pacientes con fibrilación auricular, mayor tiempo de CEC y mayor uso de vasoaminas y corticoides. Por tanto, es necesario conocer las particularidades de cada población, para gestionar el control glucémico con protocolos específicos para diferentes perfiles epidemiológicos.

Glycaemic control during the COVID-19 pandemic: A catastrophe or a sign of hope for the person with type 1 Diabetes Mellitus?

INTRODUCTION: In a person with type 1 diabetes, any change concerning daily routine may lead to changes in glycaemic control. This study aimed to evaluate the impact of work and lockdown on glycaemic control in adults with type 1 diabetes. MATERIAL AND METHODS: A retrospective cohort was stratified into three activity groups (g1-students/telework/laid-off; g2-unemployed/retired; g3-work without lockdown). Continuous and categorical variations (reductions≥0.4%) in glycated haemoglobin were obtained in 2020 (t3:December/2019-March/2020; t4:April/2020-July/2020) and in homologous periods of 2019. Intragroup comparisons between years and intergroups in the same year were made. Regression models were developed to predict the variation of glycated haemoglobin in 2020. RESULTS: 241 participants were included, with a significant reduction between t4 and t3 (vs. t2 and t1) in g1 (p<0.001) and g2 (p=0.025) and in 2020 in g1 (vs. g2, p<0.001; vs. g3, p<0.001). Only g1 presented superiority in the reduction ≥0.4% in glycated haemoglobin in 2020 (vs. 2019, p<0.001; vs. g2, p<0.001; vs. g3, p<0.001). The insulin regimens were comparable and the development of hypoglycaemia was found to be superimposed between t3 and t4, except for g1, which was higher at t3 (p=0.029). G1 correlated with continuous reductions (vs. g2, p=0.001; vs. g3, p<0.001) and ≥0.4% in glycated haemoglobin in 2020 (vs. g2, OR 3.6, p<0.001; vs. g3, OR 12.7, p<0.001), regardless of the age and duration of type 1 diabetes. CONCLUSIONS: A more stable and better glycaemic control was observed in participants who transitioned from face-to-face work to total lockdown.

Metabolic control and treatment regimens in patients with type 1 diabetes in Castilla-La Mancha, 10 years later: The 2020 DIACAM1 study.

OBJECTIVE: To evaluate degree of metabolic control and treatment regimens in patients with type 1 diabetes mellitus (T1DM) enrolled in the DIACAM1 study, after 10 years of follow-up under routine clinical practice conditions. PATIENTS AND METHODS: A total of 1,465 patients enrolled in the DIACAM1 study, a multicentre, cross-sectional study conducted in Castilla-La Mancha in 2010, were analysed. Of these patients, 58 (4%) died during the 10-year follow-up period. Anthropometric, clinical, laboratory and treatment data were reviewed for 1,121 (76.5%) patients in active follow-up. RESULTS: Mean glycosylated haemoglobin (HbA1c) levels were 7.66% lower than in 2010 (p<0.001), 26% of patients achieved HbA1c levels <7%, 24.4% were obese, 51.7% had dyslipidaemia and 33.6% had hypertension. The following were found to be predictive factors for good glycaemic control (HbA1c<7%): good glycaemic control in 2010 (odds ratio [OR] 4.8); the use of intensified insulin regimens, including the Institute for Clinical Systems Improvement (ICSI) guideline and glucose monitoring (OR 2.8); no hyperlipidaemia (OR 1.97); and higher levels of education (OR 1.4). The recommended targets for lipid and blood pressure control were met by 76% of patients; 40% of the patients enrolled required drug treatment. CONCLUSIONS: Glycaemic control in patients with T1DM in Castilla-La Mancha improved after 10 years of follow-up. The use of intensified insulin regimens and technology applied to diabetes care appear to be determining factors in achieving this improvement. Despite the increase in the prevalence of cardiovascular risk factors, the majority of the patients achieved good lipid and blood pressure control.
