ABSTRACT

Introducción: La estrecha relación que existe entre diabetes mellitus tipo 2 y obesidad ha dado lugar a la creación del término "diabesidad", considerándose la nueva enfermedad del siglo XXI. La dupla entre estas produce grave lesión en el tejido hepático, músculo esquelético y sistema cardiovascular. Es importante un estilo de vida saludable y buena adherencia farmacológica para combatir esta pandemia. Objetivo: Describir aspectos generales acerca de la fisiopatología y el tratamiento de la diabesidad. Método: Se realizó una búsqueda bibliográfica no sistemática en las bases de datos Science Direct, EMBASE, LILACS, Redalyc, SciELO y PubMed. Los criterios de inclusión fueron publicaciones en inglés y español, en las que el título, palabras clave o resumen incluyen información pertinente al objetivo de estudio, periodicidad no mayor de cinco años. En la búsqueda se obtuvieron 50 artículos, de los cuales fueron seleccionados 35. Conclusión: La insulinorresistencia es el factor determinante para la progresión hacia diabetes mellitus tipo 2, en calidad de respuesta del tejido adiposo frente a altos niveles de ácidos grasos libres (lipotoxicidad), consecuencia de la obesidad, obligando al páncreas a secretar grandes cantidades de insulina, que con el tiempo compromete su funcionalidad. En la actualidad, existen diversas alternativas no farmacológicas, farmacológicas y quirúrgicas para el abordaje de la diabesidad, donde la prevención representa un aspecto de vital importancia(AU)


Introduction: The close relation among diabetes mellitus type 2 and obesity has led to the creation of the term "diabesity," considering it the new disease of XXI century. The fusion of these two diseases produces severe lesions in the hepatic tissue, the skeletal muscle and the cardiovascular system. It is important a healthy lifestyle and a good pharmacological adherence to fight this so called pandemic. Objective: Describe general aspects related to the physiopathology and treatment of diabesity. Method: It was carried out a non-systematic bibliographic search in databases like Science Direct, EMBASE, LILACS, Redalyc, SciELO and PubMed. The inclusion criteria were publications in English and Spanish language, with a periodicity of no more than 5 years, in which the title, keywords and abstract included information that will be relevant for the objective of the study. In the search 50 articles were found, of which 35 were selected. Conclusions: Insulin resistance is the key factor for the progression towards diabetes mellitus type 2, as a response of the adipose tissue to high levels of free fatty acids (lipotoxicity), which is a consequence of obesity, and obligates the pancreas to secrete big amounts of insulin that as time goes by compromises its functionality. Nowadays, there are different non-pharmacological, pharmacological and surgical alternatives to address the diabesity, in which prevention represents an aspect of vital importance(AU)

ABSTRACT

La diabetes mellitus tipo 2 (DM2) representa un problema de salud pública, debido a su alta incidencia y prevalencia en el mundo. Un método para evaluar el riesgo de desarrollar DM2 es la escala Latin American Finnish Diabetes Risk Score (LA FINDRISC). La DM2 es un factor de riesgo de enfermedad arterial periférica (EAP) la cual puede ser diagnosticada mediante el índice tobillo-brazo (ITB). Objetivo: evaluar la presencia y severidad de enfermedad arterial periférica mediante ITB y relacionarlo con el riesgo de desarrollar DM2 según LA FINDRISC. Métodos: estudio descriptivo, correlacional, de corte transversal. Se evaluaron 134 personas y se les midió glicemia capilar para descartar diabetes. Posteriormente, se realizó el LA FINDRISC y el ITB. Resultados: El puntaje LA FINDRISC y la glicemia alteradas en ayunas aumentaron proporcionalmente (R2=0,5). Esta relación no se observó entre LA FINDRISC y el ITB arrojado por la población general. Sin embargo, al seleccionar los pacientes con vasos no comprimibles aparece una correlación positiva (R2=0,36) entre los dos instrumentos diagnósticos. Conclusión: LA FINDRISC y el ITB son instrumentos de diagnósticos no invasivo, sencillos y válidos para detectar riesgo de desarrollar DM2, y detectar presencia y severidad de enfermedad arterial periférica, respectivamente(AU)


Type 2 diabetes mellitus (DM2) represents a public health problem, due to its high incidence and prevalence in the world. One method to assess the risk of developing DM2 is the Latin American Finnish Diabetes Risk Score (LA FINDRISC) scale. DM2 is a risk factor for peripheral arterial disease (PAD) which can be diagnosed using the ankle-brachial index (ABI). Objective: to evaluate the presence and severity of peripheral arterial disease using ABI and to relate it to the risk of developing DM2 according to LA FINDRISC. Methods: descriptive, correlational, cross-sectional study. 134 people were evaluated, and capillary glycemia was measured to rule out diabetes. Subsequently, the LA FINDRISC and the ITB were held. Results: The LA FINDRISC score and impaired fasting blood glucose increased proportionally (R2 = 0.5). This relationship was not observed between LA FINDRISC and the ITB showed by the general population. However, when selecting patients with non-compressible vessels, a positive correlation (R2 = 0.36) appears between the two diagnostic instruments. Conclusion: FINDRISC and ITB are simple and valid non-invasive diagnostic instruments to detect the risk of developing DM2, and detect the presence and severity of peripheral arterial disease, respectively(AU)

ABSTRACT

Social vulnerability has proved to be an independent risk factor for hypoglycemia in patients with diabetes. In some countries, patients who are in a vulnerable situation are assisted in the public health system which provides free medical care. This study compares the prevalence of hypoglycemia among patients with type 2 diabetes (T2D), in public versus private sector and its relationship with social vulnerability. This multicentric descriptive study included 600 patients with T2D from public and private care institutions of Argentina. Socioeconomic level (SEL) was evaluated through the Marketing Argentinean Association survey. Number of severe, documented symptomatic and asymptomatic hypoglycemias were registered. Among the patients included, 66% were assisted in the public sector. The 41% of patients (n = 246) registered at least 1 episode of any hypoglycemia event being more prevalent in the public sector compared to the private sector (50% vs. 22%). In the adjusted analysis it was observed a greater risk of hypoglycemia in public sector (OR 4, 95% CI 2.65-6.04) and in patients that did not have diabetological education (OR 2.28 95% CI 1.35-3.84). Similarly, unemployment (OR 5.04 95% CI 2.69-9.46), and marginal SEL (OR 60.79 95% CI 14.89-248.13) increased the risk of hypoglycemia. Several factors related to social vulnerability as unemployment, marginal SEL and poor sanitary education showed a significant increase in the hypoglycemia risk. Professionals working with people with diabetes must take into account these factors for a safe treatment of the disease.


La vulnerabilidad social ha demostrado ser un factor de riesgo independiente de hipoglucemia en pacientes con diabetes. Los pacientes que se encuentran en situación de vulnerabilidad social reciben asistencia en el sistema de salud pública que brinda atención médica gratuita. Este estudio compara la prevalencia de hipoglucemia en pacientes con diabetes tipo 2 en el sector público frente al privado y su relación con la vulnerabilidad social. Se realizó un estudio multicéntrico descriptivo que incluyó 600 pacientes con diabetes tipo 2 de instituciones de atención pública y privada de Córdoba. El nivel socioeconómico se evaluó a través de la encuesta de la Asociación Argentina de Marketing que evalúa la dimensión social, educativa y económica para estratificar el nivel socioeconómico. Se registró el número de hipoglucemias graves, documentadas sintomáticas y asintomáticas. El 66% de los pacientes pertenecían al sector público. El 41% de los pacientes (n = 246) registró al menos 1 episodio de cualquier evento de hipoglucemia. En el análisis ajustado, se observó un mayor riesgo de hipoglucemia en el sector público (OR 4, 95% CI 2.65-6.04), en pacientes que no tenían educación diabetológica previa (OR 2.28, 95% CI 1.35-3.84), en desempleados (OR 5.04, 95% CI 2.69-9.46) y en aquellos con nivel socioeconómico marginal (OR 60.79 95% CI 14.89-248.13). Factores relacionados con la vulnerabilidad social como el desempleo, el nivel socioeconómico marginal y educación sanitaria deficiente mostraron un aumento en el riesgo de hipoglucemia. Los profesionales que trabajan con personas con diabetes deben tener en cuenta estos factores para un tratamiento seguro de la enfermedad.

ABSTRACT

La diabetes tipo 2 es una enfermedad relevante debido al aumento de su prevalencia en mayores de 50 años. Objetivo: Determinar la participación familiar en la prevención de complicaciones de pacientes con diabetes tipo 2 que ingresan en la Unidad de Cuidados Intensivos - Hospital General IESS Mila-gro, enero a junio del 2019. Metodología: tuvo un enfoque cuantitativo, descriptivo-deductivo, no experimental de corte transversal. Se diseñó un formulario con 13 preguntas que responde a los objetivos del estudio. Del universo de 210 pacientes ingresados se tomó una muestra conformada por 68 pacientes con sus respectivos familiares, seleccionada mediante muestreo no probabilístico, de los cuales el 64.7% pertenecen a género masculino, siendo las edades más afectadas los de 61 a 80 años, que viven en la zona rural (33.82%). Resultados: demostraron que el desconocimiento de los familiares sobre la enfermedad y sus complicaciones es uno de los factores más relevantes, con el 85.29%; el tiempo de evolución de la enfermedad es de seis a ocho años (52.94%); la participación en la administración de medicamentos es mayoritariamente proporcionada por su cónyuge (38,24%); la situación laboral es la limitante principal en el cuidado del paciente (55.88%), siendo el nivel de de-pendencia moderada-severa el principal problema (44.12%); el incumplimiento de las indicaciones médicas representada por el 54.41%, presentando la hiperglicemia (44.12%), y la nefropatía (65.45%), la hipertensión (43.75%) como las complicaciones más relevantes; el índice de mortalidad es de 27.94%. Conclusión: Se encontró que la participación familiar in-fluye de manera significativa en el cuida-do de estos pacientes, ya que permiten prevenir las complicaciones por diabetes tipo 2, como parte de las estrategias de salud pública para enfrentar las enfermedades crónicas no transmisibles(AU)


Type 2 diabetes is a relevant disease due to the increase in its pre-valence in people over 50 years of age. Objective: To determine the family partici-pation in the prevention of complications in patients with type 2 diabetes admitted to the Intensive Care Unit - General Hos-pital IESS Milagro, January to June 2019. Methodology: it had a quantitative, des-criptive-deductive, non-experimental cross-sectional approach. A form with 13 questions in order to answers the objec-tives of the study, was designed. From the universe of 210 admitted patients, a sample was made up of 68 patients with their respective relatives, selected by means of non-probability sampling, of which 64.7% belong to the male gender, the most affected ages being those be-tween 61 and 80 years of age, who live in the rural area (33.82%). Results: they showed that the ignorance of the relatives about the disease and its complications is one of the most relevant factors, with 85.29%. The evolution time of the disease is six to eight years (52.94%). Your spou-se (38.24%), mostly provides participa-tion in the administration of medications. The labor situation is the main limitation in patient care (55.88%), with the level of moderate-severe dependency being the main problem (44.12%); non-complian-ce with medical indications represented by 54.41%, presenting hyperglycemia (44.12%), and kidney disease (65.45%), hypertension (43.75%) as the most rele-vant complications; the mortality rate is 27.94%. Conclusion: It was found that family participation significantly influences the care of these patients, since they allow preventing complications from type 2 diabetes, as part of public health strate-gies to deal with chronic non-communicable diseases(AU)

ABSTRACT

SUMMARY In diabetics, foot deformities are risk factors that increase the risk of amputation as a result of developing ulcers. However, knowledge of the influence of plantar stiffness is still limited. The main objective was to describe connections between the degree of stiffness of the ankle, atypical amputation, and the Foot Posture Index (FPI). METHODS 62 diabetic patients, 58 with type 2 and 4 with type 1 (average age 63.35 years) were included. Records of foot deformities were included; A range of motion test of the ankle joint was used to determine the degree of stiffness. An exploratory analysis of the association of foot position and the degree of rigidity was performed. RESULTS The dorsal flexion range of the ankle was 9.6 ± 5.1 0, 13.8 ± 5.9 0 and 17.2 ± 6.5 0 and 20.5 ± 6.8 0 to 45, 67, 89 and 111 N respectively in the amputated feet., And 14 patients (22.58%) had a high level of pronation of IPF with an average value of 3.7 ± 2.629, CI (3.032.-4.367) in amputated feet compared to non-amputees. We use the device "Iowa ankle range of motion" (IAROM) to determine the differences in ankle stiffness. Proper IPF was associated with the presence of amputation and an increase in stiffness CONCLUSIONS There was an increase in the degree of limitation of movement of the ankle, as a greater force was applied. Comparing FPI between the groups, there was a higher frequency of prone feet in the group of amputees


RESUMO Nos diabéticos, as enfermidades nos pés são fatores de risco, que aumentam o risco de sofrerem uma amputação, como resultado do desenvolvimento de úlceras. Contudo, o conhecimento sobre a influência da rigidez plantar ainda é limitado. O objetivo principal foi descrever conexões entre o grau de rigidez do tornozelo, a amputação atípica e o Foot Posture Index (FPI). MÉTODOS 62 diabéticos, 58 com tipo 2; e 4 com tipo 1 (idade média de 63.35 anos). Incluindo o registro de deformidades do pé; teste de classificação do movimento da articulação do tornozelo, para determinar o grau de rigidez. Realizou-se uma análise exploratória da associação da posição do pé com o grau de rigidez. RESULTADO A classificação de flexão dorsal do tornozelo foi de 9.6 ± 5.1 0, 13.8 ± 5.9 0 e de 17.2 ± 6.5 0 e 20.5 ± 6.8 0 a 45, 67, 89 e 111 N respectivamente nos pés amputados, e 14 pacientes (22.58%) teve alto nível de pronação de FPI com um valor médio de 3.7 ±2.629, IC(3.032.-4.367) em pés amputados com relação aos não amputados. Utilizamos o dispositivo "Iowa ankle range of motion" (IAROM) para determinar as diferenças de rigidez do tornozelo. O FPI pronado foi associado à presença de amputação e um aumento da rigidez. CONCLUSÕES Aumento do grau de limitação do movimento do tornozelo; à medida que se aplicava uma força maior. Comparando FPI entre os grupos existentes maior frequência de pés pronados no grupo de amputados.

ABSTRACT

Resumen La diabetes mellitus es una enfermedad crónica, compleja, multifactorial, que se caracteriza por alteración en el metabolismo de la glucosa, las grasas y las proteínas. Los pacientes que la padecen con frecuencia cursan con hiperglucemia y la enfermedad arterial coronaria es la principal causa de muerte. Las comorbilidades que se asocian a la diabetes son: sobrepeso y obesidad, hipertensión arterial sistémica, dislipidemia aterogénica y en algunos pacientes enfermedad vascular periférica, daño renal, neuropatía y retinopatía. El descontrol crónico de la enfermedad se asocia a mayor susceptibilidad a infecciones, las cuales generalmente cursan con pocos síntomas, pero generalmente se magnifica la hiperglucemia, lo cual empeora el curso de las infecciones. Desde diciembre de 2019, cuando se identificó la enfermedad producida por uno de los coronavirus (coronavirus 2 del síndrome respiratorio agudo grave, SARS-CoV-2) y que ha sido llamada enfermedad por coronavirus 2019 (COVID-19), ha habido algunos reportes que asocian la presencia de diabetes con un mayor riesgo de mortalidad. En este artículo de revisión nos hemos enfocado en cuatro puntos específicos: 1) epidemiología de la prevalencia y de la mortalidad de COVID 19 en la población general y en la población con diabetes mellitus tipo 2; 2) fisiopatología relacionada con la unión del SARS-CoV-2 a los receptores en sujetos con diabetes; 3) la respuesta inmunológica inducida por el SARS-CoV-2, y 4) el tratamiento ambulatorio y hospitalario que se recomienda en los pacientes con diabetes que se infectan con SARS-CoV-2.


Abstract Diabetes mellitus is a complex, multifactorial, chronic disease characterized by impaired metabolism of glucose, fats and proteins. Patients who suffer from it frequently have hyperglycemia and coronary artery disease is the leading cause of death. The comorbidities associated with diabetes are overweight and obesity, systemic arterial hypertension, atherogenic dyslipidemia and in some patients peripheral vascular disease, kidney damage, neuropathy and retinopathy. Chronic lack of control of the disease is associated with increased susceptibility to infections, which generally have few symptoms, but hyperglycemia is generally magnified, which worsens the course of infections. Since December 2019, when the disease caused by one of the coronaviruses (coronavirus 2 of severe acute respiratory syndrome, SARS-CoV-2) was identified and has been called coronavirus disease 2019 (COVID-19), there have been some reports that associate the presence of diabetes with an increased risk of mortality. In this review article we have focused on four specific points: 1) epidemiology of the prevalence and mortality of COVID 19 in the general population and in the population with type 2 diabetes mellitus; 2) pathophysiology related to the binding of SARS-CoV-2 to receptors in subjects with diabetes; 3) the immune response induced by SARS-CoV-2, and 4) the outpatient and hospital treatment recommended in patients with diabetes who become infected with SARS-CoV-2.

ABSTRACT

Abstract: Gingivitis and periodontitis are associated with a negative impact on Oral Health Related Quality of Life (OHRQoL), exerting a significant influence on aspects related to the patients' function and esthetics. Periodontitis has been associated with several systemic conditions, including adverse pregnancy outcomes, cardiovascular diseases, type 2 diabetes mellitus (DM), respiratory disorders, fatal pneumonia in hemodialysis patients, chronic renal disease and metabolic syndrome. The aim of this paper was to review the results of different periodontal treatments and their impacts on patients' OHRQoL and systemic health. Non-surgical and surgical periodontal treatments are predictable procedures in terms of controlling infection, reducing probing pocket depth and gaining clinical attachment. In addition, the treatment of periodontitis may significantly improve OHRQoL and promote a reduction in the levels of systemic markers of inflammation, including some cytokines associated with cardiovascular diseases. Studies have also suggested that periodontal treatment may improve glycemic control in patients with DM. Strategies and actions for preventing the onset and recurrence of periodontitis, and the challenges facing the field of periodontology in the XXI century are presented in this review.

ABSTRACT

Abstract The evidence is inconclusive regarding the effect of periodontal treatment on glycemic control and systemic inflammation in patients with type 2 diabetes (T2D) and periodontitis Objective: To evaluate the effect of scaling and root planing (SRP) on the metabolic control and systemic inflammation of patients with type 2 diabetes (T2D). Methodology: A literature search was conducted using the MEDLINE database via PubMed and the Cochrane Central Register of Controlled Trials, from their oldest records up to July 2018. Only randomized clinical trials (RCT) were considered eligible for evaluating the effect of periodontal treatment on markers of metabolic control [glycated hemoglobin (HbA1C)] and systemic inflammation [C-reactive protein (CRP)] in patients with T2D. The quality of the studies was evaluated using the Cochrane Collaboration risk assessment tool. Meta-analyses were performed for HbA1c and CRP using random effects models. The size of the overall intervention effect was estimated by calculating the weighted average of the differences in means (DM) between the groups in each study. Heterogeneity was assessed using the Q-statistic method (x2 and I²). The level of significance was established at p<0.05. Results: Nine RCT were included. SRP was effective in reducing HbA1c [DM=0.56 (0.36-0.75); p<0.01] and CRP [DM=1.89 (1.70-2.08); p<0.01]. No heterogeneity was detected (I2=0%, p>0.05). Conclusions: SRP has an impact on metabolic control and reduction of systemic inflammation of patients with T2D.

ABSTRACT

SUMMARY INTRODUCTION Type 2 diabetes mellitus compromises physical, psychological, economic, and social life. OBJECTIVES To identify and compare the quality of life, depression, functional performance, and physical activity in patients with type 2 diabetes mellitus who use insulin or not. METHODS A observational, descriptive, cross-sectional, comparative study involving 100 patients (50 use insulin and 50 do not) from a Teaching Hospital. Questionnaires used: Identification and Socioeconomic Profile; SF-36; Hospital Anxiety and Depression Scale; Visual Analogue Scale for Pain; Canadian Occupational Performance Measure, and International Physical Activity Questionnaire. RESULTS Sample composed predominantly by middle-aged, female, married, retired, and with incomplete elementary school individuals. There is impairment in all domains of quality of life, being more intense in functional capacity, physical limitations, pain, social aspects, limitation by emotional aspects, and mental health (P<0.05). There is a significant prevalence of anxiety or depressive symptoms in the groups, especially in those using insulin. However, the occurrence of the corresponding psychiatric disorders is unlikely (P<0.05). There was no significant difference in neuropathic pain between the groups (P=0.2296). Functional impairment is similar in both groups regarding self-care activities (P=0.4494) and productivity (P=0.5759), with a greater deterioration of leisure time in patients on insulin (P=0.0091). Most of them practice physical activity, predominantly walking, with no significant difference when comparing the groups (P>0.05), as well as in the other modalities. CONCLUSION Insulinized patients present greater impairment of functional capacity and socialization, as well as greater neuropathic pain, anxiety, and depressive symptoms.


RESUMO INTRODUÇÃO Diabetes mellitus tipo 2 compromete física, psicológica, econômica e socialmente. OBJETIVOS Identificar e comparar qualidade de vida, depressão, desempenho funcional e exercício físico em pacientes com diabetes mellitus tipo 2 insulinizados ou não. MÉTODOS Estudo individuado, observacional, descritivo, transversal, comparativo envolvendo 100 pacientes (50 utilizam insulina e 50 não) em um hospital escola. Instrumentos utilizados: Ficha de Identificação e Perfil Socioeconômico; SF-36; Escala Hospitalar de Ansiedade e Depressão; Escala Visual Analógica de Dor; Medida Canadense de Desempenho Ocupacional e Questionário Internacional de Atividade Física. RESULTADOS Amostra composta, predominantemente, por indivíduos de meia-idade, sexo feminino, casados, ensino fundamental incompleto e aposentados. Há comprometimento de todos os domínios da qualidade de vida, sendo mais intenso nos insulinizados em capacidade funcional, limitação por aspectos físicos, dor, aspectos sociais, limitação por aspectos emocionais e saúde mental (P<0,05). Importante prevalência de sintomas ansiosos ou depressivos nos grupos, principalmente nos em uso de insulina, porém a ocorrência dos transtornos psiquiátricos correspondentes é improvável (P<0,05). Não houve diferença significativa da DNP entre os grupos (P=0,2296). O prejuízo da funcionalidade é semelhante em relação a atividades de autocuidado (P=0,4494) e produtividade (P=0,5759) nos dois grupos, havendo maior deterioração do lazer em usuários de insulina (P=0,0091). A maioria pratica atividade física, tendo a caminhada a maior adesão, sem diferença significativa ao comparar os grupos (P>0,05), repetindo-se nas demais modalidades. CONCLUSÃO Pacientes insulinizados apresentaram maior prejuízo da capacidade funcional e na socialização, assim como referem maiores dores neuropáticas e sintomas ansiosos e depressivos.

ABSTRACT

ABSTRACT Purpose: To evaluate the usefulness of fundus autofluorescence imaging of diabetic patients without retinopathy to investigate early retinal damage. Methods: Fundus autofluorescence images of patients with type 2 diabetes mellitus without retinopathy (diabetic group) and age-sex matched healthy patients (control group) were recorded with a CX-1 digital mydriatic retinal camera after detailed ophthalmologic examinations. MATLAB 2013a software was used to measure the average pixel intensity and average curve width of the macula and fovea. Results: Fifty-six eyes of 28 patients, as the diabetic group, and 54 eyes of 27 healthy patients, as the control group, were included in this study. The mean aggregation index was 168.32 ± 37.18 grayscale units (gsu) in the diabetic group and 152.27 ± 30.39 gsu in the control group (p=0.014). The mean average pixel intensity value of the fovea was 150.87 ± 35.83 gsu the in diabetic group and as 141.51 ± 31.10 gsu in the control group (p=0.060). The average curve width value was statistically higher in the diabetic group than in the control group (71.7 ± 9.2 vs. 59.4 ± 8.6 gsu, respectively, p=0.03). Conclusion: Fundus autofluorescence imaging analysis revealed that diabetic patients without retinopathy have significant fluorescence alterations. Therefore, a noninvasive imaging technique, such as fundus autofluorescence, may be valuable for evaluation of the retina of diabetic patients without retinopathy.


RESUMO Objetivo: Avaliar a utilidade da autofluorescência do fundo de olho de pacientes diabéticos sem retinopatia para investigar lesões precoces na retina. Métodos: Imagens de autofluorescência do fundo de olho de pacientes com diabetes mellitus do tipo 2 sem retinopatia (grupo diabético) e indivíduos saudáveis pareados por idade e sexo (grupo controle) foram registrados com uma câmera retiniana digital midriática CX-1 após exames oftalmológicos detalhados. O software MATLAB 2013a foi usado para medir a intensidade média do pixel e a largura média da curva da mácula e fóvea. Resultados: Cinquenta e seis olhos de 28 pacientes, como o grupo diabético, e 54 olhos de 27 indivíduos saudáveis, como grupo controle, foram incluídos neste estudo. O índice médio de agregação foi de 168,32 ± 37,18 unidades de escala de cinza (gsu) no grupo diabético e em 152,27 ± 30,39 gsu no grupo controle (p = 0,014). O valor médio da intensidade de pixel na fóvea foi de 150,87 ± 35,83 gsu no grupo diabético e de 141,51 ± 31,10 gsu no grupo controle (p=0,060). O valor médio da largura da curva foi estatisticamente maior no grupo diabético do que no grupo controle (71,7 ± 9,2 vs. 59,4 ± 8,6 gsu, respectivamente; p = 0,03). Conclusão: A análise por imagens de autofluorescência de fundo de olho revelou que pacientes diabéticos sem retinopatia apresentam alterações significativas de fluorescência. Portanto, uma técnica de imagem não invasiva, como a autofluorescência de fundo de olho, pode ser valiosa para a avaliação da retina de pacientes diabéticos sem retinopatia.

ABSTRACT

ABSTRACT Objective We denote the four major factors related to the development of type 2 diabetes (T2D) as "diabetes factor" (DF); increased insulin resistance (IR); decreased glucose effectiveness (GE); and the first-and-second-phase of insulin secretion (FPIS, SPIS). The level of hemoglobin (Hb) was found to be related to IR and FPIS, but no-known studies focused on its role in relation to SPIS and GE. In this study, we aim to evaluate the relationships between Hb and all four DFs in the same individual. Subjects and methods We randomly enrolled 24,407 men and 24,889 women between 30 and 59 years old. IR, FPIS, SPIS and GE were measured according to equations published in our previous studies. To compare the slopes between Hb and the four DFs with different units, we converted their units to percent of change per unit of increased Hb. Results Age, HDL-cholesterol and GE were higher in women; BMI, blood pressure, LDL-cholesterol, TG, Hb, FPIS, SPIS and IR were higher in men. After they were converted into percentage, the closeness of their relationships to Hb, from the highest to the lowest, were GE, IR, FPIS and SPIS for women and IR, GE, FPIS and SPIS for men. GE was the only one negatively related to Hb. Conclusions Our data showed that IR, FPIS and SPIS were both positively and, GE negatively, related to the Hb in adult Chinese. For women, GE had the closest association with Hb; for men, it was IR. Both phases of insulin secretion had relatively weaker relationships than IR and GE.

ABSTRACT

Abstract Background: Myocardial performance index (MPI), demonstrates both systolic and diastolic functions of the left ventricle. Presystolic wave (PSW) is frequently detected on Doppler examination of the left ventricular outflow tract and possible mechanism of PSW is impaired LV compliance and left ventricular stiffness. Objective: To investigate the relationship between PSW and MPI in type 2 diabetic patients. Method: A total of 129 type 2 diabetic patients were included in this study. Patients were divided into two groups according to the presence of PSW on Doppler echocardiography. There were 90 patients (38 male, mean age 57.77 ± 10.91 years) in the PSW-positive group and 39 patients (13 male; mean age: 55.31 ± 11.29 years) in the PSW-negative group. The p values of < 0.05 were considered statistically significant. Results: MPI was higher in PSW- positive group (0.63 ± 0.17vs 0.52 ± 0.13, p < 0.001). In addition, subclinical left ventricle dysfunction (LVD) was higher in the PSW- positive group (p = 0.029). Univariate analysis showed that the presence of PSW associated with abnormal MPI (p = 0.031). Pearson correlation analysis showed that PSW velocity correlated with MPI (r: 0.286, p = 0.006). Conclusion: Presence of the PSW on Doppler examination was associated with subclinical LV dysfunction in patients with DM type 2. This easy-to-perform echocardiographic parameter may be related to subclinical LVD among patients with type 2 DM.


Resumo Fundamento: O índice de performance miocárdica (IPM) avalia as funções sistólica e diastólica do ventrículo esquerdo. A onda pressistólica (OPS) é geralmente detectada no exame Doppler da via de saída do ventrículo esquerdo e seus possíveis mecanismos são complacência prejudicada e rigidez do ventrículo esquerdo. Objetivo: Investigar a relação entre OPS e IPM em pacientes com diabetes tipo 2. Método: 129 pacientes com diabetes tipo 2 foram incluídos no estudo. Os sujeitos foram alocados em dois grupos, com base na presença de OPS no exame ecocardiográfico com Doppler. Foram incluídos 90 pacientes (38 homens, idade média 57,77 ± 10,91 anos) no grupo OPS-positiva e 39 pacientes (13 homens; idade média 55,31 ± 11,29 anos) no grupo OPS-negativa. Valor de p < 0,05 foi considerado para significância estatística. Resultados: O IPM foi mais alto no grupo OPS-positiva (0,63 ± 0,17 vs 0,52 ± 0,13, p < 0,001). Além disso, a disfunção ventricular esquerda subclínica (DVE) foi maior no grupo OPS-positiva (p = 0,029). Análise univariada mostrou associação de OPS com IPM anormal (p = 0,031), assim como o coeficiente de correlação de Pearson mostrou correlação entre velocidade de OPS e IPM (r: 0,286, p = 0,006). Conclusão: Presença de OPS na ecocardiografia com Doppler foi associada à DVE subclínica em pacientes com diabetes tipo 2. Esse exame ecocardiográfico de fácil execução pode ser relacionado à DVE subclínica entre pacientes com diabetes tipo 2.

ABSTRACT

ABSTRACT Objective Type 2 diabetes (T2DM) is characterized by the progressive deterioration of pancreatic islet β-cell function over time and insulin resistance. Knowing more about the differences in pancreatic islet function in T2DM patients who have had diabetes for different lengths of time can help improve therapy for T2DM. Subjects and methods We conducted a cross-sectional study to compare islet β-cell function and insulin resistance in T2DM patients (n = 3,254) who had had diabetes for different lengths of time and those in normal controls (n = 794) using ANOVA and LSD analysis. Results We found that compared with that in normal controls, HOMA-β in T2DM patients with a history of diabetes of less than 1 year was lower (approximately 52% of that of normal controls, p = 0.003), while HOMA-IR in these patients was higher (approximately 50% of that of normal controls, p = 0.007). Compared with that in other diabetic patients, HOMA-β in patients with a history of diabetes of more than 30 years was the lowest. HOMA-IR in patients with a history of diabetes of between 20 and 30 years was lower than that in other diabetic patients (p < 0.05). Conclusions There were obvious decreases in HOMA-β and increases in HOMA-IR in T2DM patients with a history of diabetes of less than 1 year compared with those in normal controls. Therefore, early screening and intervention for T2DM might help improve islet function and delay the progression of diabetes.

ABSTRACT

RESUMO O objetivo deste trabalho foi comparar o pico de torque e flexibilidade dos membros inferiores de indivíduos com e sem diabetes mellitus tipo 2 (DM2). O método foi o estudo com grupos expostos e não expostos ao DM2. Foram incluídos indivíduos com diagnóstico médico de DM2, encaminhados para eletroneuromiografia, e não expostos ao DM2. Foram excluídos da pesquisa indivíduos com idade superior a 70 anos ou que, por algum motivo, não conseguiram realizar um ou dois dos testes. A amostra foi não probabilística, composta por 64 indivíduos: 34 (53,1%) expostos ao DM2 e 30 não expostos; 50 (78,1%) eram do sexo feminino, a idade média era de 60,7±7,1 anos, e o membro inferior dominante era o direito em 57 (89,1%) dos indivíduos. Comparando indivíduos com e sem diagnóstico de DM2, observou-se redução do torque de flexão à esquerda, em velocidade angular de 120° (25,94±2,26 vs. 33,79±2,4nm, p=0,027, respectivamente). Relatou-se menor valor do torque de dorsiflexão à direita, em velocidade angular de 60°, dos diabéticos em relação aos não diabéticos (10,95±0,89 vs. 13,95±0,96nm, p=0,033, respectivamente). Ao comparar indivíduos com DM2, com e sem diagnóstico de neuropatia diabética periférica (NDP), notou-se maior déficit de flexão entre os indivíduos neuropatas em comparação com não neuropatas (46,57±9,47 vs. 11,63±13,85nm, p=0,049, respectivamente). Não foram encontradas diferenças estatisticamente significativas ao comparar os grupos de expostos e não expostos ao DM2 e diabéticos neuropatas e não neuropatas.

El método fue el estudio con grupos expuestos y no expuestos al DM2. Se incluyeron individuos con diagnóstico médico de DM2, encaminados para electroneuromiografía, y no expuestos al DM2. Se excluyeron de la investigación a individuos mayores de 70 años o que, por algún motivo, no pudieron realizar una o dos de las pruebas. La muestra fue no probabilística, compuesta por 64 individuos: 34 (53,1%) expuestos al DM2 y 30 no expuestos; 50 (78,1%) eran de sexo femenino, la edad media era de 60,7±7,1 años, y el miembro inferior dominante era el derecho en 57 (89,1%) de los individuos. En comparación con individuos con y sin diagnóstico de DM2, se observó reducción del torque de flexión a la izquierda, en velocidad angular de 120° (25,94±2,26 frente a 33,79±2,4nm, p=0,027, respectivamente). Se ha reportado un menor valor del torque de dorsiflexión a la derecha, en velocidad angular de 60°, de los diabéticos con relación a los no diabéticos (10,95±0,89 frente a 13,95±0,96nm, p=0,033, respectivamente). Al comparar individuos con DM2, con y sin diagnóstico de neuropatía diabética periférica (NDP), se notó mayor déficit de flexión entre los individuos neuropáticos en comparación con no neuropáticos (46,57±9,47 vs. 11,63±13,85nm, p=0,049, respectivamente). No se encontraron diferencias estadísticamente significativas al comparar los grupos de expuestos y no expuestos al DM2 y los diabéticos neuropáticos y no neuropáticos.


ABSTRACT To compare the muscle strength and flexibility of the lower limbs of individuals with and without T2DM. The method was a study of the types exposed and unexposed to T2DM. Individuals diagnosed with T2DM, individuals referred to electromyography, and those unexposed to T2DM were included. The exclusion criteria were: individuals over 70 years old; those who for some reason failed to complete one or both tests. The study population consisted of 64 individuals; 34 (53.1%) exposed to DM and 30 unexposed, 50 (78.1%) were female, the mean age was 60.7±7.1 and the dominant lower limb was right in 57 (89.1%) individuals. Comparing individuals with and without a diagnosis of DM, one observed a reduction in the flexion torque on the left at a 120 ° angular velocity in diabetics individuals compared with nondiabetic patients, 25.94±2.26 vs 33.79±2, 4nm, p=0.027, respectively. The reduction in dorsiflexion torque on the right, at a 60 ° angular velocity was observed in diabetics compared with nondiabetic patients, 10.95±0.89 vs. 13.95±0.96nm, p=0.033, respectively. When comparing diabetic individuals with and without a diagnosis of PDN, one observed a greater flexion deficit among neuropathic individuals when compared with non-neuropathic individuals, 46.57±9.47 vs 11.63±13.85nm, p=0.049, respectively. No statistically significant differences were found when comparing groups exposed and unexposed to T2DM, and neuropathic and non-neuropathic diabetics.

ABSTRACT

La neuropatía autonómica cardiovascular en el paciente diabético (NACD) se define como una complicación crónica de la diabetes de tipo microangiopática, que se expresa en disautonomía del sistema cardiovascular. Se realizó un estudio descriptivo transversal cuyo objetivo fue la caracterización epidemiológica y clínica de los pacientes diabéticos tipo 2 con NACD que acudieron a la Unidad de Diabetes del CCR-ASCARDIO de la ciudad de Barquisimeto, estado Lara durante el mes de diciembre del año 2014. La muestra estuvo conformada por 68 individuos diabéticos tipo 2, con una prevalencia de NACD según la prueba de RV del 63,2%, por ortostatismo de 45,6% y por taquicardia sinusal inapropiada de 8,8%. Hubo un predominio del género femenino y un mayor porcentaje de pacientes con NACD no tenían control metabólico de la diabetes y tenían más de 5 años con la enfermedad. En conclusión, se sugiere el diagnóstico precoz de la DM así como la identificación temprana de síntomas que sugieran el desarrollo de disautonomía por deterioro neuropático del sistema cardiovascular en estos pacientes(AU)


Cardiovascular autonomic neuropathy in diabetic patients (CAN) is defined as a chronic complication of diabetes (DM) of the microangiopathic type, which is expressed as dysautonomia of the cardiovascular system. We performed an observational descriptive cross-sectional study to characterize clinically and epidemiologically type 2 diabetic patients with CAN that were attended in December 2014 at the Unidad de Diabetes of CCR-ASCARDIO in Barquisimeto, Lara state. The sample consisted of 68 type 2 diabetic patients with a prevalence of CAN according to the RINES VALCARDI (RV) test of 63.2%, by orthostatism of 45.6% and by the presence of inappropriate sinus tachycardia of 8.8%. In patients with CAN, there was female predominance and a greater percentage of patients had more than five years with diabetes and no metabolic control their disease. In conclusion, it is important to make an early diagnosis of diabetes and clearly identify symptoms that suggest dysautonomia in these patients(AU)

ABSTRACT

Physical training is recommended in several studies and guidelines for the control of type 2 diabetes mellitus (DM2) and its complications. We performed a systematic review about the effects of aerobic training (AT), resistance (RT) or the combination of both (AT/ RT), on glycated hemoglobin (HbA1c) in patients with DM2. Therefore, we included 15 clinical trials with at least 12 weeks duration about training program or recommendations of physical exercise, that evaluated the reduction in HbA1c levels in patients with DM2. Information was obtained on training modality (AT, RT or AT / RT), training parameters, duration and weekly training frequency. The results showed increases in peak or maximal oxygen uptake, exercise tolerance time and muscle strength, depending on the type of training, and a reduction in HbA1c levels. We conclude that exercise training is associated with reductions of HbA1c in patients with DM2. Thus, it can be a complementary tool in the management of these patients.

ABSTRACT

ABSTRACT Objectives: The aims of this study are to investigate which of the seven selected predictive equation for estimating basal metabolic rate (BMR) is the best alternative to indirect calorimetry (IC) and to evaluate the dietary energy intake in patients with type 2 diabetes. Subjects and methods: Twenty-one patients with type 2 diabetes participated in this diagnostic test study. Clinical and laboratorial variables were evaluated as well as body composition by absorptiometry dual X-ray emission (DXA) and BMR measured by IC and estimated by prediction equations. Dietary intake was evaluated by a quantitative food frequency questionnaire. Data were analyzed using Bland-Altman plots, paired t-tests, and Pearson's correlation coefficients. Results: Patients were 62 (48-70) years old, have had diabetes for 8 (2-36) yeas, and 52.4% were females. The mean body composition comprised a fat-free mass of 49.8 ± 9.4 kg and a fat mass of 28.3 ± 7.2 kg. The energy intake was 2134.3 ± 730.2 kcal/day and the BMR by IC was 1745 ± 315 kcal/day. There was a wide variation in the accuracy of BMR values predicted by equations when compared to IC BMR measurement. Harris-Benedict, Oxford, FAO/WHO/UNO equations produced the smallest differences to IC, with a general bias of < 8%. The FAO/WHO/UNO equation provided the best BMR prediction in comparison to measured BMR. Conclusion: In patients with type 2 diabetes, the equation of the FAO/WHO/UNO was the one closest to the BMR values as measured by IC.

ABSTRACT

Type 2 diabetes mellitus (T2D) is a common endocrine and metabolic disorder, and poses threats to human health worldwide. Recently, microRNAs (miRNAs) have been suggested to play important roles in the pathophysiology of T2D. In this study, we explored the role of miR-3666 in T2D. miR-3666 was significantly down-regulated in the serum of T2D patients when compared to that of healthy volunteers, and miR-3666 expression level was negatively correlated with blood glucose levels of T2D patients. Overexpression of miR-3666 inhibited cell proliferation, reduced insulin secretion, and promoted cell apoptosis of pancreatic β-cell line (INS-1 cells). On the other hand, knockdown of miR-3666 had the opposite effects in INS-1 cells. The bio-informatics analysis using TargetScan revealed that adiponectin (ADIPOQ) was a downstream target of miR-3666, and the interaction between miR-3666 and ADIPOQ was validated by luciferase reporter assay. In addition, miR-3666 negatively regulated the mRNA and protein expression of ADIPOQ. Overexpression of ADIPOQ promoted insulin secretion after glucose stimulation, promoted cell proliferation, inhibited cell apoptosis, and partially abolished the effects of miR-3666 overexpression on insulin secretion, cell proliferation, and cell apoptosis of INS-1 cells. In conclusion, our results revealed that miR-3666 inhibited pancreatic cell proliferation, reduced insulin sensitivity, and promoted apoptosis by targeting ADIPOQ.

ABSTRACT

Las complicaciones crónicas de la diabetes mellitus pueden resultar en una baja calidad de vida, por lo cual la aplicación de un índice pronóstico puede ser una herramienta útil para mejorar esta situación.Objetivo: Asociar la presencia actual de complicaciones crónicas de la Diabetes Mellitus tipo 2, con las presentes 10 años antes aplicando la formula RECODE. Métodos: estudio observacional, analítico, longitudinal, retro-prospectivo en pacientes mayores de 30 años, se evaluaron las complicaciones crónicas en el presente y se aplicó la formula RECODE tomando los datos de la historia anterior. Tratamiento estadístico: estadística descriptiva para cada variable a través de análisis de frecuencia y porcentaje, además de la formula RECODE. Resultados: Se evaluaron 593 pacientes, con 308 exclusiones. El promedio de edad fue 63 años ± 15,5 DE. Hubo leve predominio de mujeres en 55%. En 75% de los pacientes había hipertensión. Las complicaciones crónicas encontradas fueron: nefropatía diabética 44%, neuropatía en 41% y afección cardiovascular en 14%. La mortalidad fue de 2%. Al confrontar las complicaciones crónicas que predice la formula RECODE en la actualidad, con los resultados de la fórmula con datos de 10 años previos, se encontró que todos los eventos ya estaban presentes durante la evaluación actual y la fórmula estimaba una menor frecuencia de los hallazgos documentados, con excepción de la cardiopatía isquémica o enfermedad cerebrovascular. Conclusión: La presencia de complicaciones crónicas actuales fue mayor a la que estimada según RECODE 10 años antes; aún así se concluye que dicha fórmula es útil para el cálculo de riesgo de complicaciones crónicas(AU)

Objective: To associate the present chronic complications of Type 2 Diabetes Mellitus, with the result of the application of the RECODE formula in the recent past. Methods: observational, analytical, longitudinal, retro-prospective study of patients older than 30 years. the chronic complications were assesed in the clinical record and at the present time using the RECODE formula as well as for the former 10 years Statistics:descriptive statistics for each variable through frequency and percentage analysis, in addition to the RECODE formula. Results: 593 patients were evaluated, with 308 exclusions. The average age was 63 years ± 15.5 SD. There was a slight predominance of women in 55%. Hypertension was present in 75%. Among the chronic complications found were: diabetic nephropathy 44%, followed by neuropathy in 41% and cardiovascular disease in 14%. Mortality was 2%. When comparing the present chronic complications predicted by the RECODE formula, with the results of the formula dated 10 years before we found that all the events were already present during the current evaluation and the formula estimated a lower frequency of the documented findings, with the exception of ischemic heart disease or cerebrovascular disease in 10 patients. Conclusion: The presence of current chronic complications was greater than estimated according to RECODE 10 years before.(AU)

ABSTRACT

The study was performed to estimate the association of hypertension and dyslipidaemia with increasing body weight and obesity in Type II diabetics of Lahore, Pakistan. An observational study was conducted by enrolling 2708 obese diabetics from four diabetes care centres of Lahore, Pakistan. Data was collected for a period of 7 months. Associations were estimated using chi-square, binary and multinomial logistic regression. Data suggested that blood pressure, systolic and diastolic, exhibited continual increase with increasing body weight and obesity class in diabetes patients with 41.8% increase in the prevalence of hypertension in obesity class III subjects (OR; 1.91, p=0.02). Likewise, triglycerides and total cholesterol exhibited continual increase in their mean values with increasing obesity, i-e., an overall increase in the prevalence of dyslipidaemia of 27.2% in obesity class 3 subjects (OR; 1.94, p=0.29). Taken together, this data suggested that hypertension is potentially associated with increasing obesity in diabetics, while dyslipidaemia demonstrated plausible association only with obesity class 3.
