Introduction: Physical exercise is one of de fundamental pillars in the treatment of people with diabetes. Adjusting the therapeutic regimen allows safe participation and high performance of physical activity. Aim: To describe the effects and importance of physical exercise in people with diabetes mellitus. Method: A documentary investigation was carried out. It was used as a search engine for scientific information Google Academic. Books, research and review articles from different databases were evaluated: LILACS, PubMed, SciElo, Cochrane and web pages in Spanish, English and Portuguese. Results: In people with diabetes, aerobic physical exercises are recommended, they increase insulin sensitivity and have a favorable influence on metabolic control. Resistance exercises are also beneficial in order to improve muscle strength. Before developing an exercise program, the person with diabetes mellitus must undergo a detailed medical evaluation. The indication of the type of exercise, its intensity and duration must be personalized. Glycemic control before, during and after exercise is essential. Encouraging play in young children is the best way to ensure enjoyable physical activity. Conclusions: The physical exercise should be indicated in people with diabetes mellitus due to its multiple health- related benefits; its indication must be individualized.

Effect of the COVID-19 quarantine on metabolic control in children and adolescents with type 1 diabetes.

INTRODUCTION: Metabolic control in type 1 diabetes (T1D) depends on many factors such as eating habits, exercise and lifestyle. The objective of this study was to investigate how these factors were affected during the coronavirus disease 2019 (COVID-19) lockdown and impacted metabolic control in children with T1D. MATERIALS AND METHOD: One hundred children with T1D were enrolled in the study. Anthropometric measurements, snack and meal frequency, carbohydrate consumption, HbA1c levels, and exercise patterns were recorded and compared before and after the lockdown. Subjects were divided into two subgroups-patients with decreased and patients with increased HbA1c levels after the lockdown-and comparisons of the same parameters were also made between these two subgroups. RESULTS: In the overall group, the mean HbA1c level was significantly higher after the lockdown compared to before (p=0.035). Meal schedules changed due to delayed sleep and waking times, and total daily carbohydrate consumption increased in the subgroup with increased HbA1c while it decreased in the subgroup with decreased HbA1c (p<0.001 for both). CONCLUSION: Our study supports the notion that blood sugar management in children with T1D worsened during the COVID-19 pandemic. Although it is not possible to explain this with any one factor, some behavioral changes observed in our study, such as inactivity, irregular meal frequency and timing, and irregular sleep and waking patterns appeared to be associated with blood sugar management.

Introduction: the lock down during the COVID-19 pandemic meant great changes in the care of patients with diabetes, which could affect metabolic control. Objectives: to assesse whether there were changes in metabolic control in children under 18 years of age with type 1 diabetes followed up in the Nutrition and Diabetes Service of the Pedro de Elizalde Children's General Hospital (HGNPE), after the social isolation measures implemented during the COVID-19 pandemic and estimate the frequency of acute complications and the variation of the Z-score of Body Mass Index (BMI). Materials and methods: longitudinal, retrospective, observational study. Patients aged 1 to 18 years old with type 1 diabetes of more than one year of evolution, with regular follow-up in the HGNPE, who had been evaluated, with determination of glycosylated hemoglobin, between December 2019 and March 2020 (pre-quarantine) and between December 2020 and March2021. Of these patients, those who attended a subsequent control between December 2020 and March 2021 were considered for a comparative analysis. Results: 88 patients were included, of which 59 underwent a control in the second period. The initial HbA1c was 8,8% (IIC 25-75 = 7,42-9,4) and the subsequent one was 8,3% (IIC 25-75 = 7,2-9,95), the z-score of initial BMI was 0,35 ± 1,02 and the subsequent one was 0,37 ± 0,97, with non-significant differences in both cases. 15% (n = 9) of the patients had acute complications. Conclusion: no significant changes were found in HbA1c and BMI z-score between the periods compared

A dietary pattern high in full-fat dairy and sweetened beverages is associated with glycated hemoglobin and weight in Mexican patients with type-2 diabetes / Un patrón dietético con alto contenido de lácteos enteros y bebidas azucaradas se asocia con la hemoglobina glicosilada y el peso en pacientes mexicanos con diabetes de tipo 2

Objective the aim of this study was to identify dietary patterns in a sample of patients with type-2 diabetes, and to evaluate their association with markers of metabolic control. Methods: a cross-sectional study in 395 patients with type-2 diabetes in primary care was conducted. Fasting blood levels of glycated hemoglobin (A1c), glucose, total cholesterol, low- (LDL-c) and high-density lipoprotein cholesterol (HDL-c), and triglycerides were measured. Waist circumference, body mass index (BMI), and blood pressure were evaluated. Dietary intake was assessed by a food frequency questionnaire, and dietary patterns were derived by cluster analysis. Three dietary patterns were identified: ‘fruits and vegetables', ‘dairy and sweetened beverages', and ‘diverse with alcohol'. Results: an association between the ‘dairy and sweetened beverages' dietary pattern and A1c levels was identified (ß = 0.61; 95 % CI; 0.09, 1.12, p = 0.021), considering the ‘fruits and vegetables' dietary pattern as the reference group. We also observed a trend towards an adjusted increased risk of A1c ≥ 7 % (odds ratio [OR]: 1.56; 95 % CI: 0.92, 2.64; p = 0.099) and an increased risk of BMI ≥ 25 kg/m2 (OR: 2.62, 95 % CI: 1.20, 5.71, p = 0.015) among patients in the ‘dairy and sweetened beverages' dietary pattern as compared to the reference group. Conclusions a dietary pattern characterized by a high intake of full-fat dairy and sweetened beverages was associated with higher A1c levels and increased risk of high glucose and BMI when compared to a dietary pattern with a higher consumption of fruits and vegetables (AU)

Clinical characteristics and management of type 1 diabetes in Spain. The SED1 study.

OBJECTIVES: To determine the sociodemographic and clinical profile of a representative sample of people with type 1 diabetes mellitus (DM1) in Spain and identify factors associated with glycemic control. MATERIAL AND METHODS: A cross-sectional observational study was carried out in adults and children with DM1 treated in 75 Spanish public hospitals, geographically distributed in order to be representative of the Spanish population. Within each center, the patients were included on a consecutive basis as they visited the clinic. They were interviewed, and their clinical histories were reviewed. A descriptive statistical analysis was made, and factors associated with HbA1c were analysed using multivariate linear regression analysis. RESULTS: A total of 647 patients were included: 55.3% females, aged 36.6 ±â€¯14.4 years, 97.2% Caucasians, BMI 24.7 ±â€¯4.4 kg/m2 (12.1% ≥ 30 kg/m2), and 74.0% had secondary / university education. A total of 20.2% were active smokers. The mean time from the diagnosis of DM1 was 17.9 ±â€¯12.0 years. A total of 48.7% presented comorbidities: 19.3% retinopathy and 16.4% hypothyroidism. As regards treatment for DM1, 76.5% received basal-bolus insulin therapy and 20.7% continuous subcutaneous insulin infusion (CSII); 51.0% of the patients used an insulin/carbohydrate ratio (ICR), with 4.6 ±â€¯1.6 self-monitored capillary blood glucose (SMCBG) measurements a day, and 24.8% used continuous glucose monitoring (CGM). The mean HbA1c value was 7.6 ±â€¯1.1% (30% below 7%). Metabolic control improved (lower HbA1c) with more daily SMCBG (B = -0.053; p = 0.009), a higher educational level (B = 0.461; P < 0.001), greater number of hypoglycemia episodes (B = -0.253; P = 0.018) and carbohydrate counting (B = -0.190; P = 0.048), and worsened the longer the duration of the disease (B = 0.010; P = 0.010), higher total dose of insulin (B = 0.010; P < 0.0001), poorer adherence to diet (B = 0.650; P < 0.0001) and a family history of DM (B = -0.233; P = 0.007). CONCLUSIONS: The management of patients with DM1 in Spain, as well as the treatment they receive, is similar to that seen in other Western countries. Blood glucose control is associated with educational level, disease duration, and the characteristics of treatment and self-care.

Experiencia en el uso de fibrina rica en plaquetas en pacientes con pie diabético / Experience in the use of platelet-rich fibrin in patients with diabetic foot

Resumen Objetivos: Describir las características clínicas y de laboratorio de los pacientes diabéticos tipo 2 (DM2) en tratamiento con fibrina rica en plaquetas (FRP) en el Hospital Clínico Herminda Martín entre los años 2014 y 2016. Materiales y Método: Se revisaron las fichas clínicas de todos los pacientes tratados con FRP en el policlínico de biomateriales en busca de los valores de HbA1c y glicemia, además de otras variables clínicas y de laboratorio que pudieren estar relacionadas con la evolución de las heridas de pie diabético. Se estableció tres grupos de comparación según el tiempo de cicatrización en cicatrización rápida (tiempo percentil 75). Resultados: De un universo de 147 pacientes con DM2 se reportan resultados de 85 (58%). El promedio de edad fue de 61 años, con una glicemia promedio de 243 g/dL y HbA1c de 9,4%. Presentaron un contaje plaquetario dentro de los parámetros normales (promedio 279 plaquetas/mm3). Se encontraron diferencias estadísticas en la escala de valoración de heridas, específicamente en la valoración del puntaje total, así como los parámetros como extensión, profundidad, y dolor entre los grupos de cicatrización rápida y lenta. No se evidenciaron diferencias en el nivel de HbA1c o glicemia en los grupos de cicatrización rápida o lenta, como tampoco en otras variables como edad, creatinina, recuento de plaquetas. Conclusión: No se encontró una asociación entre la velocidad de cicatrización y el nivel de HbA1c en individuos tratados con FRP.

Aims: To describe the clinical and laboratory characteristics of type 2 diabetic patients (DM2) treated with Platelet Rich Fibrin (FRP) at Hospital Clínico Herminda Martín between 2014 and 2016. Materials and Method: Analytical study that includes information from a secondary database. The clinical records of all patients treated with FRP at the Biomaterials Polyclinic were reviewed to search the HbA1c and glycemia values, as well as other clinical and laboratory variables that could be related to the evolution of diabetic foot wounds. Three comparison groups were established according to the healing time in rapid (time 75th percentile). Results: From a universe of 147 patients with DM2, results of 85 (58%) are reported. The average age in the included patients was 61 years. They had an average glycaemia of 243 g/dL, and HbA1c of 9.4%. They presented a platelet count within normal range (average 279 platelets/mm3). Statistical differences between the fast and slow healing groups were found in the wound assessment scale, specifically in the assessment of the total score, extension, depth, and pain. There were no differences in the HbA1c or glycemia level in the fast or slow healing groups, nor in other variables such as age, creatinine, and platelet count. Conclusion: No association was found between healing speed and HbA1c level in individuals treated with FRP.

The presence of microvascular complications is associated with a poor evolution of metabolic control in patients with type 1 diabetes mellitus.

OBJECTIVE: To report the evolution of metabolic control and to assess the clinical and metabolic factors associated with the presence of microvascular complications in patients with type 1 diabetes mellitus (T1DM). MATERIAL AND METHODS: This was a retrospective, observational study analysing clinical, laboratory, and therapeutic data from a registry of patients with T1DM created in 2010. RESULTS: Data recorded from 586 patients (males: 50.2%; mean age: 36.1±13.5 years; T1DM duration: 18.0±12.1 years) followed for a mean of 6.0±3.1 years were assessed, and 8133 HbA1c levels (13.2±7.6 measurements/patient) were analysed, with a mean evolutionary HbA1c of 7.9%±1.2%. The mean annual HbA1c level gradually improved from 8.6%±1.6% in 2010 to 7.5%±1.4% in 2019, with 34.3% and 69.0% of patients having HbA1c levels ≤7% and ≤8% respectively. Patients with T1DM duration of <10 years and ≥20 years, non-smokers, CSII users, and those using the insulin/carbohydrate ratio had better current and evolutionary HbA1c levels. The presence of microvascular complications was independently associated with T1DM lasting ≥20 years, the presence of HBP, and evolutionary HbA1c≥7.0%. CONCLUSION: A progressive but still inadequate improvement in metabolic control over 10 years was seen in patients with T1DM. Poor metabolic control (mean HbA1c over 10 years ≥7%) was independently associated with the presence of microvascular complications.

Acute panendothelial retinal leakage in a patient with diabetes mellitus type 1 with a poor metabolic control.

Ophthalmological diabetic complications are one of the main causes of blindness worldwide, so careful diagnostic and management is important. The screening plans implemented in our population made possible an early diagnosis and treatment, trying to reduce the consequences. Diabetic retinopathy is widely known, however we present the case of a rare retinal condition, acute panedothelial retinal leakage. It typically affects patients with type 1 DM and poor glycemic control. Its diagnosis is important since a strict metabolic control is sufficient for its resolution, avoiding aggressive therapies.

¿Por qué asociar la enfermedad periodontal inmunoinflamatoria crónica con el descontrol metabólico del paciente diabético? / Why to link the chronic immune-mediated inflammatory disease with the absence of metabolic control of a patient suffering from diabetes?

Introducción: La asociación entre la diabetes mellitus y las periodontopatías se ha reportado en numerosos estudios. Se acepta que la interrelación entre ambas es bidireccional. Un alto porcentaje de los estudios epidemiológicos, así como de los estudios en animales de experimentación, sugieren que la presencia de una condición tiende a aumentar el riesgo y la severidad de la otra. Objetivo: Consolidar núcleos teóricos y evidencias clínicas que esclarezcan la relación entre la enfermedad periodontal inmunoinflamatoria crónica y el descontrol metabólico del paciente diabético. Métodos: Se realizó una revisión de la literatura disponible a través de la búsqueda automatizada en las bases de datos: PubMed, Scielo y Google Académico, en el período de enero - junio de 2020. La estrategia de búsqueda se realizó a nivel de título, resumen y palabras clave de los artículos, con el uso de conectores lógicos. Se evaluaron artículos de revisión, de investigación, metaanálisis, de autores cubanos e internacionales que hicieran referencia específicamente al tema de estudio a través del título. Resultados: Fueron seleccionados 29 textos científicos, escritos en idioma español e inglés, publicados entre el año 2005 y el 2019, de los cuales 27 eran artículos científicos de revistas y 2 libros de texto. Conclusiones: La mayor parte de las publicaciones revisadas sobre el tema, avalan la relación entre enfermedad periodontal y descontrol metabólico diabético, basados en estudios clínicos y hemoquímicos. Existen investigadores que sugieren continuidad de estudios para perfeccionar metodologías, esclarecer teorías y sobredimensionamiento de la asociación. La valoración de las periodontopatías, como factor de riesgo para el descontrol metabólico del diabético, debe pasar de una interrogante a una estrategia promocional, preventiva y terapéutica(AU)

Introduction: The association between Diabetes Mellitus and periodontopathies has been reported in numerous studies. It is accepted that the interrelation between the two is bidirectional. A high percentage of epidemiological studies, as well as studies in experimental animals, suggest that the presence of one condition tends to increase the risk and severity of the other. Objective: Consolidate theoretical nuclei and clinical evidence that clarify the relationship between chronic immune-mediated inflammatory periodontal disease and the metabolic decontrol of the diabetic patient. Methods: A review of the available literature was performed through the automated search in the following databases: PubMed, Scielo and Google Scholar, in the period January-June 2020. The search strategy was carried out through the title, abstract and keywords levels of the articles, with the use of logic connectors. Review, research and meta-analysis articles and by Cuban and international authors ones were assessed and that make specific reference to the studied topic through the title. Results: 29 scientific texts were selected; those were written in Spanish and English, published between 2005 and 2019, of which 27 were articles from a scientific journal and 2 were textbooks. Conclusions: Most of the publications reviewed on the subject endorse the relation between periodontal disease and diabetic metabolic decontrol, based on clinical and hemochemical studies. There are researchers who suggest continuity of studies to improve methodologies, clarify theories and oversize the association. The evaluation of periodontopathies as a risk factor for the metabolic decontrol of the diabetic must go from a question to a promotional, preventive and therapeutic strategy(AU)

Effect of the COVID-19 quarantine on metabolic control in children and adolescents with type 1 diabetes.

INTRODUCTION: Metabolic control in type 1 diabetes (T1D) depends on many factors such as eating habits, exercise and lifestyle. The objective of this study was to investigate how these factors were affected during the coronavirus disease 2019 (COVID-19) lockdown and impacted metabolic control in children with T1D. MATERIALS AND METHOD: One hundred children with T1D were enrolled in the study. Anthropometric measurements, snack and meal frequency, carbohydrate consumption, HbA1c levels, and exercise patterns were recorded and compared before and after the lockdown. Subjects were divided into two subgroups-patients with decreased and patients with increased HbA1c levels after the lockdown-and comparisons of the same parameters were also made between these two subgroups. RESULTS: In the overall group, the mean HbA1c level was significantly higher after the lockdown compared to before (p=0.035). Meal schedules changed due to delayed sleep and waking times, and total daily carbohydrate consumption increased in the subgroup with increased HbA1c while it decreased in the subgroup with decreased HbA1c (p<0.001 for both). CONCLUSION: Our study supports the notion that blood sugar management in children with T1D worsened during the COVID-19 pandemic. Although it is not possible to explain this with any one factor, some behavioral changes observed in our study, such as inactivity, irregular meal frequency and timing, and irregular sleep and waking patterns appeared to be associated with blood sugar management.

Evaluación del control metabólico de personas con diabetes mellitus tipo 2 participantes de una intervención educativa grupal. Resultados de un análisis de conglomerados / Evaluation of metabolic control of patients with type 2 diabetes mellitus participating in a group educational intervention; results of a cluster analysis

Resumen Objetivo: evaluar los resultados de una intervención educativa grupal en diabetes mellitus tipo 2 (DM2) para determinar la capacidad de las personas participantes en el control metabólico de la enfermedad. Metodología: se realizaron diferentes análisis estadísticos; a saber, un análisis de correlación y de conglomerados mediante tres procedimientos (K medias con valores estandarizados de las variables involucradas, análisis jerárquico con variables estandarizadas) y una combinación de análisis factorial con K medias. Además, se llevó a cabo un análisis de normalización para determinar la efectividad del Programa de Intervención Nutricional en Enfermedades Crónicas. Resultados: completaron la intervención educativa 702 personas con diabetes, de las cuales la mayoría son mujeres, con edades entre 40 y 64 años. Las variables que resultaron estadísticamente significativas (p<0,001) para el análisis de conglomerados fueron glicemia posprandial, glicemia en ayunas, hemoglobina glicosilada, colesterol total y triglicéridos, donde los valores promedio disminuyeron en todas las pruebas clínicas después de la intervención educativa. Por medio de la combinación del análisis factorial y el análisis de conglomerados se generaron tres grupos: DM2 control bajo, DM2 control medio y DM2 control alto. En el análisis de normalización, se determinó que la intervención educativa del Programa de Intervención Nutricional en Enfermedades Crónicas fue efectiva. Conclusión: los resultados de estudio permitirán enfocar los objetivos terapéuticos de la intervención educativa mediante acciones propias y de seguimiento del tratamiento de una manera más certera.

Abstract Objective: Evaluate the results of a group educational intervention in type 2 diabetes mellitus (DM2) to determine the capacity of the participants in the metabolic control of the disease. Methodology: Different statistical analyzes were performed: correlation and cluster analysis using three procedures (K means with standardized values of the variables involved, hierarchical analysis with standardized variables) and a combination of factor analysis with K means. In addition, a normalization analysis was carried out to determine the effectiveness of the Nutritional Intervention Program in Chronic Diseases. Results: 702 people with diabetes completed the educational intervention, of which the majority are women, ages between 40 and 64 years old. The variables that were statistically significant (p <0.001) for the cluster analysis were postprandial glycemia, fasting glycemia, glycated hemoglobin, total cholesterol and triglycerides, where the average values decreased in all the clinical tests after the educational intervention. Three groups were generated by combining factorial analysis and cluster analysis: low control DM2, medium control DM2 and high control DM2. In the normalization analysis, it was determined that the educational intervention of the Nutritional Intervention Program in Chronic Diseases was effective. Conclusion: The results of this study will allow us to focus on the therapeutic objectives of the educational intervention through our own actions and by monitoring the treatment in a more accurate way.

Clinical characteristics and management of type 1 diabetes in Spain. The SED1 study. / Características clínicas y manejo de la diabetes tipo 1 en España. Estudio SED1.

OBJECTIVES: To determine the sociodemographic and clinical profile of a representative sample of people with type 1 diabetes mellitus (DM1) in Spain and identify factors associated with glycemic control. MATERIAL AND METHODS: A cross-sectional observational study was carried out in adults and children with DM1 treated in 75 Spanish public hospitals, geographically distributed in order to be representative of the Spanish population. Within each center, the patients were included on a consecutive basis as they visited the clinic. They were interviewed, and their clinical histories were reviewed. A descriptive statistical analysis was made, and factors associated with HbA1c were analyzed using multivariate linear regression analysis. RESULTS: A total of 647 patients were included: 55.3% females, aged 36.6±14.4 years, 97.2% Caucasians, BMI 24.7±4.4kg/m2 (12.1% ≥30kg/m2), and 74.0% had secondary / university education. A total of 20.2% were active smokers. The mean time from the diagnosis of DM1 was 17.9±12.0 years. A total of 48.7% presented comorbidities: 19.3% retinopathy and 16.4% hypothyroidism. As regards treatment for DM1, 76.5% received basal-bolus insulin therapy and 20.7% continuous subcutaneous insulin infusion (CSII); 51.0% of the patients used an insulin/carbohydrate ratio (ICR), with 4.6±1.6 self-monitored capillary blood glucose (SMCBG) measurements a day, and 24.8% used continuous glucose monitoring (CGM). The mean HbA1c value was 7.6±1.1% (30% below 7%). Metabolic control improved (lower HbA1c) with more daily SMCBG (B=-0.053; p=0.009), a higher educational level (B=0.461; P<0.001), greater number of hypoglycemia episodes (B=-0.253; P=0.018) and carbohydrate counting (B=-0.190; P=0.048), and worsened the longer the duration of the disease (B=0.010; P=0.010), higher total dose of insulin (B=0.010; P<0.0001), poorer adherence to diet (B=0.650; P<0.0001) and a family history of DM (B=-0.233; P=0.007). CONCLUSIONS: The management of patients with DM1 in Spain, as well as the treatment they receive, is similar to that seen in other Western countries. Blood glucose control is associated with educational level, disease duration, and the characteristics of treatment and self-care.

Asociación entre sentido de coherencia y control glucémico en personas con Diabetes Mellitus tipo 2 / Associação entre Senso de Coerência e controle glicêmico em pessoas com Diabetes Mellitus Tipo 2 / Association between Sense of Coherence and glycemic control in people with Type 2 Mellitus Diabetes

Objetivo: Evaluar la asociación entre sentido de coherencia y control glucémico en adultos con Diabetes Mellitus tipo 2. Métodos: Estudio de tipo transversal desarrollado durante el año 2018 en el cual fueron encuestados 220 diabéticos de tres unidades de Salud de la Secretaría de Salud del Estado de Jalisco en Ciudad Guzmán, México. Se les aplicó el instrumento SOC-13 para sentido de coherencia y el control glucémico se evaluó por medio del nivel de hemoglobina glucosilada que se obtuvo del expediente médico. Los datos se analizaron por medio del análisis de regresión logística. Resultados: Se obtuvieron resultados con un total de 220 participantes en un rango de edad entre 23 y 69 años de los que el 67% presentó control glucémico inadecuado y el 33% control glucémico adecuado; de los encuestados con control glucémico inadecuado el 24% refirió puntuaciones bajas de sentido de coherencia, mientras que el 96% de quienes tienen control glucémico adecuado obtuvo puntuaciones medio/alta de sentido de coherencia. Los análisis de regresión logística arrojan que el sentido de coherencia se asocia significativamente con el control glucémico (OR = 7.2; 95% C.I: 2.0-24.7; p = 0.002) después de ajustar los análisis por diversas variables confusoras como sexo, apego al plan alimenticio, actividad física, ausencia de complicaciones y ausencia de tabaquismo. Conclusión: Los diabéticos con puntuaciones medio/altas de sentido de coherencia tienen hasta 7 veces más probabilidad de tener control glucémico adecuado que diabéticos con puntuaciones bajas de sentido de coherencia independientemente de variables intervinientes.

Objetivo: Avaliar a associação entre senso de coerência e controle glicêmico em adultos com diabetes mellitus tipo 2. Métodos: Estudo transversal desenvolvido durante 2018, com 220 diabéticos de três unidades de saúde da Secretaria de Saúde do Estado de Jalisco na cidade de Guzmán, México. Aplicou-se o instrumento SOC-13 para senso de coerência, e avaliou-se o controle glicêmico por meio do nível de hemoglobina glicosada obtido nos prontuários. Assim, obtiveram-se os dados por análise de regressão logística. Resultados: Os 220 participantes tinham faixa etária de 23 a 69 anos, dos quais 148 (67%) apresentavam controle glicêmico inadequado e 72 (33%) controle glicêmico adequado; 24% dos pesquisados com controle glicêmico inadequado relataram escores baixos para senso de coerência, enquanto 96% daqueles com controle glicêmico adequado obtiveram escores médios/ altos para senso de coerência. As análises de regressão logística mostram que o senso de coerência está significativamente associado ao controle glicêmico (OR=7,2; IC 95%: 2,0-24,7; p=0,002) após ajustar as análises para variáveis de confusão, como sexo, adesão ao plano alimentar, atividade física, ausência de complicações e ausência de tabagismo. Conclusão: Diabéticos, com escores médios/altos de senso de coerência, têm até 7 vezes mais chances de apresentar controle glicêmico adequado do que diabéticos com baixos escores de senso de coerência, independentemente das variáveis intervenientes.

Objective: To evaluate the association between a sense of coherence and glycemic control in adults with type 2 Mellitus Diabetes. Methods: Cross-sectional study, developed during 2018, 220 diabetics from three health units of the Secretaria de Salud del Estado de Jalisco in Ciudad Guzmán, Mexico, the SOC-13 instrument was applied for a sense of coherence, glycemic control was evaluated through the level of glycosylated hemoglobin obtained from the medical record, the data was analyzed through logistic regression analysis. Results: Results were obtained with a total of 220 participants in an age range of 23 to 69 years of which 67% presented inadequate glycemic control and 33% adequate glycemic control; 24% of those surveyed with inadequate glycemic control reported low scores for a sense of coherence, while 96% of those with adequate glycemic control obtained medium/high scores for a sense of coherence. The logistic regression analyzes show that the sense of coherence is significantly associated with glycemic control (OR=7.2; 95% CI: 2.0-24.7; p=0.002) after adjusting the analyzes for various confounding variables such as sex, adherence to eating plan, physical activity, absence of complications and absence of smoking. Conclusion: Diabetics with medium/high scores of coherence sense are up to 7 times more likely to have adequate glycemic control than diabetics with low scores of coherence sense regardless of intervening variables.

Acute panendothelial retinal leakage in a patient with diabetes mellitus type 1 with a poor metabolic control. / Capilaropatía edematosa aguda en un paciente con diabetes mellitus tipo 1 con mal control metabólico.

Ophthalmological diabetic complications are one of the main causes of blindness worldwide, so careful diagnostic and management is important. The screening plans implemented in our population made possible an early diagnosis and treatment, trying to reduce the consequences. Diabetic retinopathy is widely known, however we present the case of a rare retinal condition, acute panedothelial retinal leakage. It typically affects patients with diabetes mellitus (DM) type 1 and poor glycemic control. Its diagnosis is important since a strict metabolic control is sufficient for its resolution, avoiding aggressive therapies.

Caracterización del estado inmunometabólico de los pacientes con diagnóstico de pie diabético / Characterization of the immunometabolic status of patients with diagnosis of diabetic foot

Introducción: El pie diabético es una alteración clínica inducida por la hiperglucemia mantenida, con o sin isquemia y previo traumatismo, lesión y/o ulceración del pie. La hiperglucemia favorece las infecciones, pero no potencia el crecimiento bacteriano, lo que sugiere la participación del sistema inmune en esta susceptibilidad. Objetivo: Caracterizar el estado inmunometabólico de los pacientes con diagnóstico pie diabético. Métodos: Se realizó un estudio descriptivo de corte transversal en 25 pacientes ingresados con diagnóstico de pie diabético, entre septiembre y diciembre de 2018 en el Hospital Universitario "Manuel Ascunce Domenéch". Las variables estudiadas fueron: edad, sexo, formas clínicas de presentación del pie diabético, complementos 3 y 4, inmunoglobulinas G y A, y hemoglobina glucosilada. Se empleó la estadística descriptiva para el análisis de los datos. Resultados: El sexo femenino representó el 60 por ciento y los pacientes con más de 70 años el 40 por ciento. La inmunoglobulina G sérica se encontró disminuida en un 28 por ciento de los pacientes con pie diabético y aumentada en otro 28 por ciento. La hemoglobina glucosilada reflejó un desbalance en el 48 por ciento de los casos. De los pacientes con descontrol metabólico, 8 (32 por ciento) mostraron alteraciones de la inmunoglobulina G y 2 del componente C3. Conclusiones: Existió un grupo de pacientes con pie diabético que presentaron alteraciones inmunológicas variables y/o descontrol metabólico. Estos podrían beneficiarse con un manejo integral a partir del uso de inmunoterapia y la prevención de complicaciones infecciosas del pie diabético(AU)

Introduction: Diabetic foot is a clinic alteration induced by persistent hyperglycemias, with or without ischemia and previous trauma, lesion and/or ulceration of the foot. Hyperglycemia favours infections, but it does not increase the bacterial growth which suggests the participation of the immune system in this sensitivity. Objective: To characterize the immunometabolic status of patients with diagnosis of diabetic foot. Methods: It was carried out a descriptive, cross-sectional study in 25 patients hospitalized with diagnosis of diabetic foot among September and December, 2018 in "Manuel Ascunce Domenech" University Hospital. The studied variables were: age, sex, clinical forms of diabetic foot, complement 3 and 4, G and A, immunoglobulins and glycosylated hemoglobine. It was used descriptive statistic for data analysis. Results: Females represented the 60 percent and patients older than 70 years were the 40 percet. Seric G immunoglobulin was found as decreased in 28 percent of the patients with diabetic foot and increased in the 28 percent. Glycosylated hemoglobine presented unbalanced in 48 percent of the cases. From the patients with metabolic decontrol, 8 (32 percent) showed alterations of G immunoglobulin and 2 in the component C3. Conclusions: There was a group of patients with diabetic foot who presented variable immunological alterations and/or metabolic decontrol. Those patients can benefit with an integral management using immunotherapy and the prevention of infectious complications of the diabetic foot(AU)

Feeding behavior pattern and glycosylated hemoglobin in people with type 2 diabetes at the beginning and end of an educational intervention. / Comportamiento del patrón de alimentación y de la hemoglobina glicosilada en personas con diabetes tipo 2, al inicio y final de una intervención educativa.

OBJECTIVE: To assess the changes in food consumption pattern and glycosylated hemoglobin levels in patients with type 2 diabetes after an educational intervention. MATERIALS AND METHODS: A descriptive study in people over 18 years of age with type 2 diabetes receiving the educational intervention provided by the health facilities of the Costa Rican Social Security. Sociodemographic, biochemical, and anthropometric variables were collected. Glycemic control was classified as good (≤7%), fair (7.1-8%), and poor (>8%). The usual daily diet record was used to assess the food consumption pattern based on the 11 criteria, divided into the following categories: poor compliance (0-3 criteria), fair compliance (4-7 criteria), and good compliance (8-11 criteria). Data collected were processed using SPSS version 16 software. A Student's t test was used for dependent samples. The impact of the educational intervention on metabolic control and food consumption pattern was determined using a McNemar test with a level of significance of 5% for hypothesis testing. RESULTS: The study sample consisted of 702 patients with a mean age of 54.5±11.6 years, 73.8% females. Mean initial glycosylated hemoglobin level was 8.8±2.14%, while final level was 7.8±1.78% (P<.05). Glycosylated hemoglobin levels less than 7% were found in 23.9% of the population at study start and in 41.3% at study end. As regard the food consumption pattern, the mean number of criteria met was 6±3 at study start and 9±2 at study end (P<.000). Mean glycosylated hemoglobin level showed at the start of intervention a similar behavior in all 3 categories of the food consumption pattern, and at the end the changes in glycosylated hemoglobin in the poor and fair compliance categories were statistically significant (P<.022 and P<.000 respectively), unlike in the good compliance category (P<.065). At the end of the intervention, of the 75.6% of the population with good compliance, 41.3% had good metabolic control (P<.0001). The educational intervention was significant (P<.000) using the McNemar test. CONCLUSION: The educational intervention approach to nutritional therapy had a positive impact on the food consumption pattern and glycosylated hemoglobin levels, showing that therapeutic education is part of the treatment of diabetes to achieve the objectives.

Education with a multimedia web platform improves knowledge and HbA1c of Mexican patients with type 2 diabetes. Open clinical trial. / La educación con una plataforma multimedia en web mejora los conocimientos y la HbA1c de pacientes mexicanos con diabetes tipo 2. Ensayo clínico abierto.

INTRODUCTION: The patient with diabetes mellitus type requires to receive education about the disease aimed at improving knowledge and skills for their control. The objective of this study is to evaluate the efficacy of nutritional therapy and education through a multimedia site on the level of knowledge and metabolic control in patients with type 2 diabetes. PATIENTS AND METHODS: Open-label clinical trial of 12 months of follow-up in 161 patients with type 2 diabetes. A total of 101 patients were assigned to the intervention group with nutrition therapy (TN) + Nutriluv (multimedia site in diabetes), 80 patients to the TN control group. The glycosylated hemoglobin (HbA1c), glucose, cholesterol, triglycerides, LDL and HDL cholesterol were measured at the beginning and end. Weight, waist circumference, percentage of fat, systolic blood pressure and diastolic blood pressure were recorded. The level of knowledge was measured with the Diabetes Knowledge Questionnaire (DKQ24). RESULTS: The knowledge in diabetes improved in the group with TN+Nutriluv compared with the TN group (P<0.05). HbA1c, HDL, diastolic blood pressure and waist circumference, improved in the group with TN+Nutriluv (P<0.05). In the group with TN, cholesterol HDL, diastolic blood pressure, waist circumference and the fat percentage was increased (P<0.05). They had a higher risk of having an HbA1c>7% who had more years of diagnosis of diabetes. CONCLUSIONS: The use of a multimedia site with education in diabetes, improves knowledge, HbA1c, and other indicators of cardiovascular risk in diabetes type 2 patients.
