ABSTRACT

OBJECTIVES@#To investigate the prevalence of diabetes mellitus (DM) among Uygur children in Hotan Prefecture of Xinjiang, China, as well as the factors influencing the development of DM.@*METHODS@#The cluster random sampling method was used to select 5 308 children, aged 4-18 years, from the middle and primary schools and kindergartens in Hotan Prefecture of Xinjiang. The survey methods included questionnaire survey and the measurement of height and weight. All subjects were tested for fasting fingertip blood glucose to investigate the prevalence of DM and impaired fasting glucose (IFG).@*RESULTS@#A total of 5 184 valid questionnaires were collected. Fourteen children (0.27%) were found to have DM, among whom 8 had type 1 DM, 2 had type 2 DM, and 4 had unclassified DM. Twenty-nine children (0.56%) were found to have IFG. There was no significant difference in the prevalence rate of DM and IFG between boys and girls (P>0.05). The prevalence rate of DM was 0.18% in the 4-<10 years group, 0.47% in the 10-<15 years group, and 0.07% in the 15-18 years group (P=0.072).The prevalence rate of IFG in the above three age groups was 0.18%, 0.94%, and 0.42%, respectively, with a significant difference among groups (P=0.007). The proportion of family history of DM and the proportion of overweight/obesity in children with DM were significantly higher than those in children without DM (P<0.05), while the proportion of children with DM who preferred coarse grains was significantly lower than that in children without DM (P<0.05).@*CONCLUSIONS@#The prevalence of DM and IFG in Uyghur children in Hotan Prefecture of Xinjiang is relatively low. There is no significant difference in the prevalence of DM among children of different genders or age groups, but the prevalence of IFG in children of different age groups is different. A family history of DM, overweight or obesity, and low intake of coarse grains might be associated with the development of DM.

ABSTRACT

This study analyzed the molecular mechanism of Huangjing Qianshi Decoction(HQD) in the treatment of prediabetes based on network pharmacology and molecular docking. The active components of HQD were identified and screened based on Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP, http://Lsp.nwu.edu.cn/tcmsp.php) and then the targets of the components and the genes related to prediabetes were retrieved, followed by identifying the common targets of the decoction and the disease. The medicinal component-target network was constructed by Cytoscape to screen key components. The protein-protein interaction(PPI) network was established by STRING and hub genes were identified by Cytoscape-CytoNCA, followed by Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) of the hub genes with R-clusterProfi-ler. Thereby, the possible signaling pathways were predicted and the molecular mechanism was deduced. A total of 79 active components of HQD and 785 diabetes-related targets of the components were screened out. The hub genes mainly involved the GO terms of tricarboxylic acid cycle, peptide binding, amide binding, hydrolase activity, and kinase activity regulation, and the KEGG pathways of AGE-RAGE signaling pathway, TNF signaling pathway, AMPK signaling pathway, IL-17 signaling pathway, and insulin signaling pathway. Western blot result showed that HQD-containing serum significantly reduced the expression of AKT1, AGE, and RAGE proteins in insulin resistance model cells. HQD's treatment of prediabetes is characterized by multiple pathways, multiple targets, and multiple levels. The main mechanism is that the components zhonghualiaoine, baicalein, kaempferol, and luteolin act on AKT1 and inhibit the AGE-RAGE axis.

ABSTRACT

Objetivo: estimar el riesgo de prediabetes según los factores que presentan los participantes de un programa de ejercicio físico de la provincia de Chota, Perú. Metodología: estudio observacional, transversal y retrospectivo, desarrollado con 112 participantes pertenecientes a un programa de ejercicio físico. Se utilizó una guía de interpretación para analizar los factores de riesgo y la prediabetes en los participantes, la cual fue adaptada de una asociación norteamericana y dos instituciones de salud peruanas. Las pruebas estadísticas utilizadas fueron el odds ratio de prevalencia (ORP), la fracción etiológica poblacional (FEP) y el chi cuadrado de independencia. Resultados: el sedentarismo (ORP = 3,62), el exceso de triglicéridos (TGC) (ORP = 2,26) y el sobrepeso (ORP = 2,22) fueron los factores de riesgo identificados en los participantes. Según la FEP, si se interviene de manera adecuada y oportuna sobre estos factores, disminuiría la frecuencia de prediabetes en 8,57, 15,24 y 21,40 %, respectivamente. Conclusiones: los factores de riesgo de prediabetes en los usuarios estudiados fueron el sedentarismo, el exceso de TGC y el sobrepeso, resaltando al sedentarismo como el de mayor implicancia. Estos factores de riesgo, que reportaron una relación estadísticamente significativa con la prediabetes, pueden ser controlados y modificados. Por lo tanto, las intervenciones preventivas y promocionales en el primer nivel de atención deben fortalecerse y efectuarse mediante un trabajo integral y sostenible, con la finalidad de disminuir las cifras de prediabetes y condiciones conexas.


Objetivo: estimar o risco de prédiabetes de acordo com os fatores apresentados pelos participantes de um programa de exercícios físicos na província de Chota, Peru. Metodologia: estudo observacional, transversal, retrospectivo, desenvolvido com 112 participantes pertencentes a um programa de exercícios físicos. Um guia de interpretação foi utilizado para analisar os fatores de risco e o pré-diabetes nos participantes, o guia foi adaptado de uma associação norteamericana e duas instituições de saúde peruanas. Os testes estatísticos utilizados foram a razão de chances (odds ratio) de prevalência (ORP), a fração etiológica populacional (FEP) e o qui-quadrado de independência. Resultados: sedentarismo (ORP = 3,62), excesso de triglicerídeos (TGC) (ORP = 2,26) e sobrepeso (ORP = 2,22) foram os fatores de risco identificados nos participantes. De acordo com o FEP, se houver intervenção adequada e oportuna sobre esses fatores de risco a frequência de pré-diabetes diminuiria em 8,57 %, 15,24 % e 21,40 %, respectivamente. Conclusões: os fatores de risco para pré-diabetes nos usuários estudados foram sedentarismo, excesso de TGC e sobrepeso, destacando-se o sedentarismo como o de maior implicação. Esses fatores de risco que obtiveram relação estatisticamente significativa com o pré-diabetes podem ser controlados e modificados; portanto, as intervenções preventivas promocionais no primeiro nível de atenção devem ser fortalecidas e realizadas por meio de um trabalho abrangente e sustentável, a fim de reduzir o número de pré-diabetes e doenças relacionadas.


Objective: To estimate the risk of prediabetes in the participants of a physical exercise program in the province of Chota, Peru. Methodology: Observational, cross-sectional and retrospective study, developed with 112 participants in a physical exercise program. An interpretation guide was used to examine risk factors and prediabetes in the participants. This guide was adapted from a North American association and two Peruvian health institutions. The statistical tests used were the prevalence odds ratio (ORP), the population etiological fraction (PEF), and the chi square of independence. Results: A sedentary lifestyle (ORP = 3.62), the excess of triglycerides (TGC) (ORP = 2.26), and overweight (ORP = 2.22) were the main risk factors identified in participants. According to the FEP, if adequate and timely intervention is made over such factors, the frequency of prediabetes would decrease by 8.57, 15.24 and 21.40, respectively. Conclusions: Prediabetes risk factors in the studied population were a sedentary lifestyle, excess of TGC and overweight, highlighting sedentary lifestyle as that with the greatest effects on health. The identified risk factors, which reported a statistically significant relationship with prediabetes, can be controlled and modified. Therefore, promotional and preventive interventions at the first level of health care must be strengthened and carried out through comprehensive and sustainable work, in order to reduce the figures of prediabetes and its related conditions.

ABSTRACT

Introducción: el inicio de la prediabetes en edades pediá-tricas se ha convertido en un problema cada vez más frecuente, donde la obesidad juega un papel relevante. Los pacientes con prediabetes en la infancia presentan una alta prevalencia de señales aterogénicas tempranas (SAT), las cuales constituyen factores de riesgo para enfermedad cardiovascular, esto conduce a una alteración precoz de la función endotelial. Objetivo: determinar la asociación entre las SAT detectadas y la aterosclerosis subclínica en niños y adolescentes con diagnóstico reciente de prediabetes. Método: se realizó un estudio descriptivo y transversal con 31 niños y adolescentes entre 5 y 18 años de edad con diagnóstico reciente de prediabetes, atendidos en el Instituto de Endocrinología de Cuba, durante noviembre 2015 a noviembre 2016. Las principales variables estudiadas fueron: edad, sexo, antecedentes patológicos familiares y personales, presencia de obesidad abdominal, tensión arterial, lipidograma, resistencia a la insulina, disfunción endo-telial (DE) y grosor íntima media carotideo (GIMC). Resultados: predominaron los adolescentes, el sexo masculino, los antecedentes familiares de diabetes mellitus tipo 2 y personales de obesidad. La obesidad abdominal, tensión arterial normal, lipidograma normal y resistencia insulínica caracterizaron a los pacientes. Se detectó DE en el 19,3 % de los pacientes y GIMC aumentado en el 58 %. En los pacientes con DE y GIMC aumentado, predominó la obesidad abdominal y la resistencia a la insulina. Conclusiones: desde el momento del diagnóstico de la prediabetes puede existir aterosclerosis subclínica en niños y adolescentes que presentan varias SAT asociadas. (AU)


Introduction: The onset of prediabetes at pediatric ages has become in a frequent problem, where obesity plays a relevant role. Patients with prediabetes in childhood have a high prevalence of early atherogenic signs, wich are risk factors for cardiovascular disease and endothelial dysfunction. Objective: To determine the association between the early atherogenic signs and subclinical atherosclerosis in children and adolescents with a recent diagnosis of prediabetes. Method: A descriptive and cross-sectional study was conducted with 31 children and adolescents between 5 and 18 years of age with recent diagnosis (up to 3 months) of prediabetes, attended at the National Institute of Endocrinology of Cuba from November 2015 to November 2016. The mains variables studied were age, sex, family and personal pathological history, presence of abdominal obesity, blood pressure, lipidograma, insulin resistance, endothelial dysfunction (ED) and carotid intima-media thickness (CIMT). Results: The male adolescents, family history of type 2 diabetes and personal of obesity prevailed. Abdominal obesity, normal blood pressure, normal lipidograma and insulin resistance characterized the patients. ED was detected in 19, 3% of the patients and CIMT increased in 58%. Abdominal obesity and insulin resistance predominated in patients with ED and CIMT increased. Conclusions: From the time of diagnosis of prediabetes there may be subclinical atherosclerosis in children and adolescents with several early atherogenic signs associated.

ABSTRACT

Resumo O objetivo deste estudo foi avaliar a prevalência de pré-diabetes e hiperglicemia intermediária em adultos brasileiros, considerando diferentes critérios diagnósticos, e estabelecer fatores associados à sua ocorrência. Análise dos dados laboratoriais da Pesquisa Nacional de Saúde, coletados em 2014 e 2015. Foram calculadas as prevalências das condições conforme critérios da Associação Americana de Diabetes (ADA) - Hemoglobina Glicada (HbA1c) 5,7 a 6,4% - e da Organização Mundial de Saúde (OMS), de 6 - 6,4% entre aqueles que não tinham critério para diabetes. Razões de prevalência (RP) brutas e ajustadas e IC 95% foram calculados por regressão de Poisson com variância robusta. A prevalência de pré-diabetes pelo critério ADA foi de 18,5% e de 7,5% pelo critério da OMS. Verificou-se um gradiente de aumento das prevalências segundo a idade da população e presença de fatores de risco como hipertensão arterial, obesidade, circunferência abdominal elevada e baixo colesterol HDL. Os menos escolarizados e os declarados pretos apresentaram prevalências superiores. Este estudo aponta um intervalo entre 7,5 a 18,5% de adultos brasileiros que apresentam pré-diabetes e hiperglicemia intermediária, além de identificar um escore de risco para a ocorrência dessa condição.


Abstract This study aimed to evaluate the prevalence of prediabetes and intermediate hyperglycemia in Brazilian adults, according to different diagnostic criteria, and establish associated factors to its occurrence. We analyzed the National Health Survey laboratory data collected from 2014 to 2015. The prevalence of the conditions was calculated according to the American Diabetes Association (ADA) diagnostic criteria based on glycated hemoglobin (HbA1c) 5.7%-6.4%, and the World Health Organization (WHO) 6-6.4%, among those without criteria for diabetes. Crude and adjusted prevalence rates (PR) and 95% CI were calculated using Poisson regression with robust variance. The prevalence of prediabetes by ADA and WHO criteria was 18.5 and 7.5%, respectively. We observed a gradient of increased prevalence by the age of the population and risk factors, like arterial hypertension, obesity, elevated waist circumference, and low HDL cholesterol levels. Less educated people and the self-declared black had a higher prevalence. This study pointed out a range from 7.5 to 18.5% of Brazilian adults with prediabetes and intermediate hyperglycemia and identified a risk score to this condition's occurrence.

ABSTRACT

RESUMEN Introducción: En Cuba, no existe consenso acerca de qué valor del índice cintura/cadera debe ser considerado de riesgo para identificar disglucemias. Objetivos: Determinar el punto de corte del índice cintura/cadera como predictor de disglucemias para ambos sexos, en personas con sospecha de padecer diabetes mellitus. Métodos: Estudio descriptivo transversal con 975 personas, de ellas 523 mujeres y 452 hombres. La muestra no fue obtenida de población general y no fue aleatoria. A los sujetos se les realizó interrogatorio, examen físico y estudios complementarios. Se determinaron distribuciones de frecuencia de las variables cualitativas y cuantitativas. Se utilizó para el procesamiento estadístico el coeficiente de correlación de Pearson, análisis de regresión logística y el análisis de curvas Receiver Operator Characteristic. Se empleó la prueba Chi Cuadrado para evaluar la significación estadística. Resultados: En ambos sexos observamos una correlación directamente proporcional y significativa entre el índice cintura/cadera y las diferentes variables estudiadas, entre ellas: glucemia en ayunas y a las 2h, insulinemia en ayunas, triglicéridos, ácido úrico y el índice de resistencia a la insulina (HOMA-IR). El colesterol se comportó de la misma forma en los hombres, pero en las mujeres se verificó una correlación débil y no significativa. El punto de corte óptimo del índice cintura/cadera, como predictor independiente de disglucemias, fue de 0,85 en las mujeres y 0,93 en los hombres. El índice cintura/cadera presentó un buen poder predictivo para identificar a sujetos con y sin disglucemias para ambos sexos y superior al de la edad. Conclusiones: El punto de corte óptimo del índice cintura/cadera, como predictor independiente de disglucemias, es de 0,85 en las mujeres y 0,93 en los hombres. Su poder predictor de disglucemias fue bueno(AU)


ABSTRACT Introduction: In Cuba, there is no consensus about what value of the waist-hip ratio must be considered as a risk to identify dysglycemia. Objectives: To determine the cut-off point of the waist-hip ratio as a predictor of dysglycemias for both sexes, in people suspected of suffering from diabetes mellitus. Methods: Descriptive cross-sectional study with 975 people, including 523 women and 452 men. The sample was not obtained from general population and it was not random. The subjects underwent interrogation, physical examination and complementary studies. There were identified frequency distributions of qualitative and quantitative variables. It was used for the statistical processing the Pearson's correlation coefficient, logistic regression analysis and the curves analysis called Receiver Operator Characteristic. It was used the chi-square test to assess the statistical significance. Results: In both sexes, it was observed a directly proportional and significant correlation between the waist-hip ratio and the different variables studied, including: fasting and after 2 hours glycemia, fasting insulinemia, triglycerides, uric acid and the insulin resistance index (HOMA-IR). Cholesterol behaved the same way in men, but in women there was a weak and not significant correlation. The optimal cut-point of the waist-hip ratio, as an independent predictor of dysglycemia, was 0.85 in women and 0.93 in men. The waist-hip ratio presented a good predictive power to identify subjects with and without dysglycemia for both sexes and it was higher than that of the age. Conclusions: The optimal cut-point of the waist-hip ratio, as an independent predictor of dysglycemia, was 0.85 in women and 0.93 in men. Its power as predictor of dysglycemia was good(AU)

ABSTRACT

Excessive consumption of carbohydrate and fat increases the risk of cardiovascular disease. We sought to determine the potential ultrastructural alterations in large blood vessels induced by a high fat and fructose diet (HFD) in a rat model of prediabetes. Rats were either fed with HFD (model group) or a standard laboratory chow (control group) for 15 weeks before being sacrificed. The harvested thoracic aorta tissues were examined using transmission electron microscopy (TEM), and blood samples were assayed for biomarkers of pre-diabetes.TEM images showed that HFD induced profound pathological changes to the aortic wall layers, tunica intima and tunica media ultrastructures in the pre-diabetic rats as shown by apoptotic endothelial cells with pyknotic nuclei, damaged basal lamina, deteriorated smooth muscle cells that have irregular plasma membranes, shrunken nucleus with clumped nuclear chromatin, damaged mitochondria and few cytoplasmic lipid droplets and vacuoles. In addition, HFD significantly (p<0.05) decreased adiponectin and increased biomarkers of lipidemia, glycaemia, inflammation, oxidative stress, vascular injury such as soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion protein 1 (sVCAM-1), endothelin-1 (ET-1), and coagulation and thrombosis such as Von Willebrand factor (vWF), and plasminogen activator inhibitor-1 (PAI-1), compared to normal levels of these parameters in the control group. Thus, we demonstrated that feeding rats with a HFDisable to develop a pre-diabetic animal model that is useful to study the aortic ultrastructural alterations.


El consumo excesivo de carbohidratos y grasas aumenta el riesgo de enfermedades cardiovasculares. Intentamos determinar las posibles alteraciones ultraestructurales en los grandes vasos sanguíneos, inducidas por una dieta alta en grasas y fructosa (HFD) en un modelo de rata de prediabetes. Las ratas se alimentaron con HFD (grupo modelo) o una comida de laboratorio estándar (grupo de control) durante 15 semanas antes de ser sacrificadas. Los tejidos de la aorta torácica recolectados se examinaron mediante microscopía electrónica de transmisión (TEM) y las muestras de sangre se analizaron para detectar biomarcadores de prediabetes. Las imágenes TEM mostraron que HFD indujo cambios patológicos profundos en las capas de la pared aórtica, túnica íntima y túnica media en la ratas pre-diabéticas como lo muestran las células endoteliales apoptóticas con núcleos picnóticos, lámina basal dañada, células musculares lisas deterioradas que tienen membranas plasmáticas irregulares, núcleo encogido con cromatina nuclear aglomerada, mitocondrias dañadas y pocas gotitas lipídicas citoplásmicas y vacuolas. Además, HFD presentó disminución significativa de adiponectina (p <0,05), y aumento de biomarcadores de lipidemia, glucemia, inflamación, estrés oxidativo, lesión vascular como la molécula de adhesión intercelular soluble 1 (sICAM-1), proteína de adhesión de células vasculares soluble 1 (sVCAM-1), endotelina 1 (ET-1), y la coagulación y la trombosis, como el factor de Von Willebrand (vWF), y el inhibidor del activador del plasminógeno-1 (PAI -1), en comparación con los niveles normales de estos parámetros en el grupo de control. Por tanto, la alimentación de ratas con HFD es capaz de desarrollar un modelo animal prediabético que es útil para estudiar las alteraciones ultraestructurales aórticas.

ABSTRACT

Type 2 diabetes (T2D) increases the risk for cerebrovascular disease (CVD) and dementia. The underlying molecular mechanisms remain elusive, which hampers the development of treatment or/and effective prevention strategies. Recent studies suggest that dyshomeostasis of amylin, a satiety hormone that forms pancreatic amyloid in patients with T2D, promotes accumulation of amylin in cerebral small blood vessels and interaction with Alzheimer's disease (AD) pathology. Overexpression of human amylin in rodents (rodent amylin does not form amyloid) leads to late-life onset T2D and neurologic deficits. In this Review, we discuss clinical evidence of amylin pathology in CVD and AD and identify critical characteristics of animal models that could help to better understand molecular mechanisms underlying the increased risk of CVD and AD in patients with prediabetes or T2D.

ABSTRACT

OBJECTIVES: This study analyzed Korea National Health and Nutrition Examination Survey data from 2007 to 2017 to assess trends in the prevalence, treatment, and control of diabetes in Korean adults ≥30 years of age. METHODS: Prevalent diabetes was defined as a fasting plasma glucose level ≥126 mg/dL, self-reported use of anti-diabetic treatment (insulin or oral anti-diabetic drugs), or diabetes diagnosis by a physician. Target levels were defined as glycosylated hemoglobin <6.5% or <7.0%, blood pressure <130/80 mmHg, and total cholesterol <200 mg/dL. All survey waves were age-standardized to the 2005 Korean census population. RESULTS: Diabetes prevalence increased from 9.6% in 2007–2009 to 10.8% in 2016-2017 (p<0.001). Impaired fasting glucose prevalence significantly increased in both genders and almost every age group. Diabetes awareness and glycemic control did not show an increasing trend; however, the treatment rate and proportion of people diagnosed with diabetes achieving target blood pressure and total cholesterol levels improved from 57.2% to 63.5% (p=0.008), from 41.1% to 53.2% (p<0.001), and from 65.0% to 78.0% (p<0.001), respectively. CONCLUSIONS: From 2007 to 2017, the prevalence of diabetes increased moderately in Korea, whereas the diabetes treatment rate and the proportion of people diagnosed with diabetes achieving target blood pressure and total cholesterol levels improved. However, awareness of diabetes and glycemic control require significant improvements. A national-level action plan is required to raise awareness about diabetes and prediabetes, with the goal of improving glycemic control and minimizing the occurrence of adverse health outcomes.

ABSTRACT

Abnormal thyroid function is associated with impaired glucose homeostasis. This study aimed to determine whether free thyroxine (FT4) influences the prevalence of prediabetes in euthyroid subjects using a cross-sectional survey derived from the Korea National Health and Nutrition Examination Survey, conducted between 2013 and 2015. We studied 2,399 male participants of >20 years of age who were euthyroid and non-diabetic. Prediabetic participants had lower FT4 concentrations than those without prediabetes, but their thyrotropin concentrations were similar. We stratified the population into tertiles according to FT4 concentration. After adjusting for multiple confounding factors, glycosylated hemoglobin (HbA1c) levels significantly decreased with increasing FT4 tertile, whereas fasting plasma glucose (FPG) levels were not associated with FT4 tertiles (HbA1c, P<0.01 in T3 vs. T1; FPG, P=0.489 in T3 vs. T1). The prevalence of prediabetes was significantly higher in T1 (odds ratio, 1.426; 95% confidence interval, 1.126 to 1.806; P<0.01) than in T3. In conclusion, subjects with low-normal serum FT4 had high HbA1c and were more likely to have prediabetes. These results suggest that low FT4 concentration is a risk factor for prediabetes in male, even when thyroid function is within the normal range.

ABSTRACT

Previous studies have suggested that iron-deficiency anemia affects glycosylated hemoglobin (HbA1c) measurements, but the results were contradictory. We conducted a retrospective case-control study to determine the effects of iron deficiency on HbA1c levels. Starting with the large computerized database of the Italian Hospital of Desio, including data from 2000 to 2016, all non-pregnant individuals older than 12 years of age with at least one measurement of HbA1c, cell blood count, ferritin, and fasting blood glucose on the same date of blood collection were enrolled. A total of 2,831 patients met the study criteria. Eighty-six individuals were diagnosed with iron-deficiency anemia, while 2,745 had a normal iron state. The adjusted means of HbA1c were significantly higher in anemic subjects (5.59% [37.37 mmol/mol]), than those measured in individuals without anemia (5.34% [34.81 mmol/mol]) (P<0.0001). These results suggest that clinicians should be cautious about diagnosing prediabetes and diabetes in individuals with anemia.

ABSTRACT

BACKGROUND: To investigate whether diabetes contributes to mortality for major types of diseases. METHODS: Six National Health and Nutrition Examination Survey data cycles (1999 to 2000, 2001 to 2002, 2003 to 2004, 2005 to 2006, 2007 to 2008, and 2009 to 2010) and their linked mortality files were used. A population of 15,513 participants was included according to the availability of diabetes and mortality status. RESULTS: Participants with diabetes tended to have higher all-cause mortality and mortality due to cardiovascular disease, cancer, chronic lower respiratory diseases, cerebrovascular disease, influenza and pneumonia, and kidney disease. Confounder-adjusted Cox proportional hazard models showed that both diagnosed diabetes category (yes or no) and diabetes status (diabetes, prediabetes, or no diabetes) were associated with all-cause mortality and with mortality due to cardiovascular disease, chronic lower respiratory diseases, influenza and pneumonia, and kidney disease. No associations were found for cancer-, accidents-, or Alzheimer's disease-related mortality. CONCLUSION: The current study's findings provide epidemiological evidence that diagnosed diabetes at the baseline is associated with increased mortality risk due to cardiovascular disease, chronic lower respiratory diseases, influenza and pneumonia, and kidney disease, but not with cancer or Alzheimer's disease.

ABSTRACT

The modalities currently employed to screen for type 2 diabetes mellitus (T2DM)/prediabetes are HbA1(c), fasting plasma glucose (FPG), and 2-hour plasma glucose (PG) during an oral glucose tolerance test (OGTT). The purpose of this review is to highlight the positive qualities and pitfalls of these diagnostic modalities and reflect on the most reasonable and effective approach to screen high risk youth. Given its inherent preanalytical advantages, glycated hemoglobin (HbA1(c)) continues to be the preferred diagnostic modality used by pediatricians to screen high risk youth. However, when the three aforementioned tests are performed in youths of different races/ethnicities, discrepant results for T2DM/prediabetes are observed. The prevalence rates for T2DM vary from 0.53% in Chinese youth (including youth of all body mass indexes) to 18.3% in high-risk, overweight, obese Korean youth. Moreover, the FPG is abnormal (>100 less than <126 mg/dL) in 15% of Korean youth versus 8.7% of Chinese youth. The prevalence rates for prediabetes are 1.49% in Chinese youth versus 21% in Emirati youth (HbA1(c), 5.7%–6.4%). The coefficient of agreement, k, between these screening tests for T2DM are fair, 0.45–0.5 across all youth. However, using HbA1(c) as a comparator, the agreement is weak with FPG (k=0.18 in German youth versus k=0.396 in Korean youth). The American Diabetes Association (ADA) Standards of Medical Care Guidelines define “high risk youth” who need to be tested for T2DM and/or prediabetes. OGTT and HbA1(c) do not always detect T2DM in similar individuals. HbA1(c) may not be an ideal test for screening Hispanic and African American youth. FPG and OGTT are suitable screening tests for youth of ethnic minorities and those with cystic fibrosis or hemoglobinopathies. Performing all three tests either together or sequentially may be the only way to encompass all youth who have aberrations in different aspects of glucose homeostasis.

ABSTRACT

This study investigated advantages and potential risks associated with drinking alcohol in Koreans based on the alcohol flush reaction. Our investigation reviewed published studies and examined moderate-drinking levels for Koreans based on modified National Institute on Alcohol Abuse and Alcoholism guidelines. Fourteen articles out of a total 198 publications were searched using PubMed, EMBASE, KoreaMed, and RISS (Research Information Sharing Service) databases and selected for review. Individuals without alcohol flush reaction (non-flushers) exhibited lower risks associated with insulin resistance, metabolic syndrome, and hyperhomocysteinemia and their 10-year cardiovascular disease risk when alcohol consumption was ≤8 drinks/wk. Conversely, risks associated with insulin resistance, metabolic syndrome, high blood pressure, prediabetes or type-2 diabetes, and high intraocular pressure and increases in carbohydrate-deficient transferrin, gamma glutamyl transferase, and blood glucose levels were present when >8 drinks were consumed. For individuals with flushing reaction (flushers), advantages were reported in relation to risks of hyperhomocysteinemia when alcohol consumption was ≤4 drinks/wk, whereas consumption of >4 drinks/wk increased the risk of insulin resistance, metabolic syndrome, high blood pressure, pre-diabetes or type-2 diabetes, high-risk colorectal adenoma, and high intraocular pressure and increased carbohydrate-deficient transferrin, gamma glutamyl transferase, and blood glucose levels. The moderate drinking level for Koreans is ≤8 drinks/wk for men aged ≤65 years and ≤4 drinks/wk for men aged over 65. For women, these limits should be half of those for men. Furthermore, individuals with flushing reaction should maintain an alcohol consumption level half of that for non-flushers.

ABSTRACT

OBJECTIVES: Nonalcoholic fatty pancreas disease (NAFPD) is characterized by excessive fat deposition in the pancreas in the absence of alcohol consumption. In this study, we aimed to detect a possible relationship between adipose tissue accumulation, prediabetes and diabetes. METHODS: This cross-sectional and retrospective study included 110 patients. Three groups were classified as controls, patients with prediabetes and patients with type 2 diabetes. The abdominal computed tomography (CT) attenuation measurement results of the pancreas were evaluated independently by two experienced radiologists. CT measurements and biochemical parameters were compared between study groups. The relationship between continuous variables was assessed by using one-way ANOVA. To determine the changes in the dependent variable for the effects on study groups, the independent variable was adjusted using ANCOVA. A p-value less than 0.05 was considered statistically significant. RESULTS: The presence of prediabetes and type 2 diabetes was correlated with a decrease in the mean Hounsfield Unit (HU) value of the pancreas (p=0.002). Age was determined to be an independent risk factor and was correlated with NAFPD (p=0.0001). When compared to the controls (p=0.041), 71% of patients with prediabetes and 67% of patients with type 2 diabetes were observed to have an increased incidence of NAFPD. Decreased serum amylase was found to be correlated with the mean HU value of the pancreas (p=0.043). CONCLUSION: NAFPD was independently correlated with both prediabetes and type 2 diabetes adjusted for age (p=0.0001) in this study. Additionally, age was determined to be an independent risk factor and was correlated with NAFPD.
