RESUMEN
BACKGROUND: In-hospital hyperglycemia poses significant risks for patients with diabetes mellitus undergoing coronary artery bypass graft (CABG) surgery. Electronic glycemic management systems (eGMSs) like InsulinAPP offer promise in standardizing and improving glycemic control (GC) in these settings. This study evaluated the efficacy of the InsulinAPP protocol in optimizing GC and reducing adverse outcomes post-CABG. METHODS: This prospective, randomized, open-label study was conducted with 100 adult type 2 diabetes mellitus (T2DM) patients post-CABG surgery, who were randomized into two groups: conventional care (gCONV) and eGMS protocol (gAPP). The gAPP used InsulinAPP for insulin therapy management, whereas the gCONV received standard clinical care. The primary outcome was a composite of hospital-acquired infections, renal function deterioration, and symptomatic atrial arrhythmia. Secondary outcomes included GC, hypoglycemia incidence, hospital stay length, and costs. RESULTS: The gAPP achieved lower mean glucose levels (167.2 ± 42.5 mg/dL vs 188.7 ± 54.4 mg/dL; P = .040) and fewer patients-day with BG above 180 mg/dL (51.3% vs 74.8%, P = .011). The gAPP received an insulin regimen that included more prandial bolus and correction insulin (either bolus-correction or basal-bolus regimens) than the gCONV (90.3% vs 16.7%). The primary composite outcome occurred in 16% of gAPP patients compared with 58% in gCONV (P < .010). Hypoglycemia incidence was lower in the gAPP (4% vs 16%, P = .046). The gAPP protocol also resulted in shorter hospital stays and reduced costs. CONCLUSIONS: The InsulinAPP protocol effectively optimizes GC and reduces adverse outcomes in T2DM patients' post-CABG surgery, offering a cost-effective solution for inpatient diabetes management.
RESUMEN
We measured plasma-derived extracellular vesicle (EV) proteins and their microRNA (miRNA) cargos in normoglycemic (NG), glucose intolerant (GI), and newly diagnosed diabetes mellitus (DM) in middle-aged male participants of the Brazilian Longitudinal Study of Adult Health (ELSA-Brazil). Mass spectrometry revealed decreased IGHG-1 and increased ITIH2 protein levels in the GI group compared with that in the NG group and higher serotransferrin in EVs in the DM group than in those in the NG and GI groups. The GI group also showed increased serum ferritin levels, as evaluated by biochemical analysis, compared with those in both groups. Seventeen miRNAs were differentially expressed (DEMiRs) in the plasma EVs of the three groups. DM patients showed upregulation of miR-141-3p and downregulation of miR-324-5p and -376c-3p compared with the NG and GI groups. The DM and GI groups showed increased miR-26b-5p expression compared with that in the NG group. The DM group showed decreased miR-374b-5p levels compared with those in the GI group and higher concentrations than those in the NG group. Thus, three EV proteins and five DEMiR cargos have potential prognostic importance for diabetic complications mainly associated with the immune function and iron status of GI and DM patients.

This study evaluated the relationship between the zinc-related nutritional status and glycemic and insulinemic markers in individuals with type 2 diabetes mellitus (T2DM). A total of 82 individuals with T2DM aged between 29 and 59 years were evaluated. The concentration of zinc in the plasma, erythrocytes, and urine was determined by the flame atomic absorption spectrometry method. Dietary intake was assessed using a 3-day 24-h recall. In addition, concentrations of serum glucose, glycated hemoglobin percentage, total cholesterol and fractions, triglycerides, and serum insulin were determined. The insulin resistance index (HOMA-IR) and ß-cell function (HOMA- ß) were calculated. The markers of zinc status (plasma: 83.3±11.9µg/dL, erythrocytes: 30.1±4.6µg/g Hb, urine: 899.1±622.4µg Zn/24h, and dietary: 9.9±0.8mg/day) were classified in tertiles and compared to insulinemic and glycemic markers. The results showed that lower zinc concentrations in plasma and erythrocytes, as well as its high urinary excretion, were associated with higher percentages of glycated hemoglobin, reflecting a worse glycemic control in individuals with T2DM (p<0.05). Furthermore, there was a significant inverse correlation between plasma zinc levels and glycated hemoglobin percentage (r=-0.325, p=0.003), and a positive correlation between urinary zinc excretion and glycemia (r=0.269, p=0.016), glycated hemoglobin percentage (r=0.318, p=0.004) and HOMA-IR (r=0.289, p=0.009). According to our study results, conclude that T2DM individuals with reduced zinc status exhibited poor glycemic control.

The impact of dietary fatty acids in atherosclerosis development may be partially attributed to their effect on macrophage cholesterol homeostasis. This process is the result of interplay between cholesterol uptake and efflux, which are permeated by inflammation and oxidative stress. Although saturated fatty acids (SAFAs) do not influence cholesterol efflux, they trigger endoplasmic reticulum stress, which culminates in increased lectin-like oxidized LDL (oxLDL) receptor (LOX1) expression and, consequently, oxLDL uptake, leading to apoptosis. Unsaturated fatty acids prevent most SAFAs-mediated deleterious effects and are generally associated with reduced cholesterol efflux, although α-linolenic acid increases cholesterol export. Trans fatty acids increase macrophage cholesterol content by reducing ABCA-1 expression, leading to strong atherosclerotic plaque formation. As isomers of conjugated linoleic acid (CLAs) are strong PPAR gamma ligands, they induce cluster of differentiation (CD36) expression, increasing intracellular cholesterol content. Considering the multiple effects of fatty acids on intracellular signaling pathways, the purpose of this review is to address the role of dietary fat in several mechanisms that control macrophage lipid content, which can determine the fate of atherosclerotic lesions.

Objective: To evaluate the impact of screening hyper and hypoglycemia measured by capillary glycemia and standard monitorization of hyperglycemic patients hospitalized in regular care units of Hospital Israelita Albert Einstein. Methods: The capillary glycemia was measured by the Precision PCx (Abbott) glucosimeter, using the PrecisionWeb (Abbott) software. The detection of hyper and hypoglycemia during the months of May/June were compared to those of March/April in 2009 and to the frequency of the diagnosis of diabetes in 2007. Results: There was an increase in the glycemia screening from 27.7 to 77.5% of hospitalized patients (p < 0.001), of hyperglycemia detection (from 9.3 to 12.2%; p < 0.001) and of hypoglycemia (from 1.5 to 3.3%; p < 0.001) during the months of May/June 2009. According to this action 14 patients for each additional case of hyperglycemia and 26 cases for each case of hypoglycemia were identified. The detection of hyperglycemia was significantly higher (p < 0.001) than the frequency of registered diagnosis related do diabetes in the year of 2007. Conclusions: the adoption of an institutional program of glycemia monitorization improves the detection of hyper and hypoglycemia and glycemia control in hospitalized patients in regular care units.

RESUMEN
The objectives of this study were: to characterize the polipharmacy in subjects with type 2 diabetes mellitus (DM2) and to verify the correlation between polipharmacy and number of medications for DM2 complications with depression indicators (Beck Depression inventory (BDI) and urinary cortisol (CORT) levels). A sample composed of 40 patients with DM2 from the Diabetes League of HCFM-USP was analyzed for depression indicators (CORT and BDI) in addition to evaluation for polipharmacy and number of DM2 complications. The results showed oral hypoglycemic agents, insulins, antihypertensives, diuretics, lipid-lowering drugs and thrombolytics are the most frequent medications used. In this sample, 75% used from 5 to 8 medicines daily and 12.5% used more than eight medicines/day; all of them used to take each medication at least 3 times daily. Between 1 and 3 DM2 complications were observed in 60% of the individuals and 22.5% showed more than 3 DM2 complications. No significant correlations were observed between depression indicators (BDI and CORT), number of medications and DM2 complications. However, positive correlation was observed between CORT and daily frequency of medication (Spearman, r = 0.319, p = 0.019).

OBJETIVO: Identificar qual de dois esquemas simplificados de monitorização da glicemia viabiliza melhor controle metabólico, em pacientes com diabetes mellitus tipo 1, ao longo de 12 meses de participação em grupos educativos. MÉTODO: Ensaio clínico cruzado, com 21 pacientes divididos em dois grupos. Eles foram submetidos a dois esquemas de monitorização: duas medidas diárias pré-prandiais alternadas e duas medidas diárias pré e pós-prandiais alternadas. A efetividade dos esquemas foi avaliada pelos níveis de HbA1c. Para estudar a variação das médias das HbA1c aplicou-se o teste não paramétrico de Friedman. RESULTADOS: Os grupos eram homogêneos ao início do estudo com relação às variáveis sócio-demográficas e clinicas(p>0,05). A variação das médias de HbA1c, ao longo do tempo para o grupo A foi de 8,48(±1,00) a 7,37(±0,99) e para o grupo B de 9,89(±0,86) a 8,34(±1,06). O resultado da análise da variação da HbA1c mostrou redução significativa nos dois grupos, nos primeiros e últimos 6 meses e ao longo dos 12 meses nos dois grupos (p<0,05). O Esquema de monitorizações pré-prandiais possibilitou o maior número e os maiores percentuais de quedas estatisticamente significativas nos níveis de hemoglobina glicada. CONCLUSÕES: Os dois esquemas melhoraram o controle metabólico e esquema pré-prandial foi mais efetivo.

RESUMEN
PURPOSE: In this study we analyzed the role played by aerobic exercise training in the plasma lipoprotein profile, prebeta 1-HDL concentration, and in the in vitro HDL3 ability to remove cholesterol from macrophages and inhibit LDL oxidation in type 2 diabetes mellitus (DM) patients and control subjects, in the fasting and postprandial states. METHODS: Healthy controls (HTC, N = 11; 1 M/10 F) and subjects with type 2 diabetes mellitus (DMT, N = 11; 3M/8F) were engaged in a 4-month aerobic training program, and compared with a group of sedentary subjects with type 2 diabetes mellitus (DMS, N = 10; 4 M/6 F). All groups were submitted to an oral fat load test to analyze all parameters, both at the beginning of the investigation protocol (basal) and at the end of the study period (final). RESULTS: Exercising did not modify body weight, BMI, plasma concentrations of total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides (TG), glucose, insulin, or HOMA-IR, but it reduced the waist circumference. The HDL3 composition did not change, and its ability to remove cell cholesterol was unaltered by aerobic training. In DMT but not in HTC, aerobic training improved 15% the HDL3 protective effect against LDL maximal oxidation rate in the fasting state, and reduced 24% the plasma prebeta 1-HDL concentration in the postprandial state, suggesting an enhanced prebeta 1-HDL conversion into larger, more mature HDL particles. In this regard, regular aerobic exercise enriched HDL2 with TG in the fasting and postprandial states in HTC and in the fasting phase in DMT. CONCLUSION: Our results show that aerobic exercise training in diabetes mellitus improves the HDL efficiency against LDL oxidation and favors HDL maturation. These findings were independent of changes in insulin resistance and of the rise of plasma HDL cholesterol concentration.

OBJECTIVES: To discuss the metabolic syndrome and identify its risk factors, including in the pediatric age group. SOURCES: Indexed review articles. SUMMARY OF THE FINDINGS: The metabolic syndrome is characterized by insulin resistance and the presence of risk factors for cardiovascular diseases and diabetes mellitus type 2. Consensus has not yet been reached on its diagnostic criteria. This review presents diagnostic criteria defined by the American Heart Association (US National Cholesterol Education Program), the American Association of Clinical Endocrinologists, the World Health Organization and the International Diabetes Federation and discusses the possibilities of applying them to children. Pathophysiologic features of the syndrome are also covered, principally those related to the perinatal period and childhood. CONCLUSIONS: The metabolic syndrome is being diagnosed with ever greater frequency, principally during adolescence. Lifestyle changes, such as to diet and level of physical activity are fundamental to prevention. Treatment with medication and, in extreme cases, with surgery should also be considered, depending on severity and age.

OBJETIVOS Discutir a síndrome metabólica e a identificação de seus fatores de risco, inclusive na faixa etária pediátrica. FONTES DE DADOS: Artigos de revisão indexados. SÍNTESE DOS DADOS:A síndrome metabólica caracteriza-se pela resistência à insulina e pela presença de fatores de risco para doenças cardiovasculares e diabetes melito tipo 2. Não existe ainda um consenso com relação a seus critérios diagnósticos. Na presente revisão, os critérios diagnósticos da Associação Americana de Cardiologia (US National Cholesterol Education Program), Associação Americana de Endocrinologistas Clínicos, Organização Mundial da Saúde e Federação Internacional de Diabetes são apresentados, e as possibilidades de aplicação dos mesmos na infância são discutidas. São também abordados os aspectos fisiopatológicos da síndrome, principalmente aqueles relacionados ao período perinatal e à infância. CONCLUSÃO: A síndrome metabólica tem sido identificada de forma cada vez mais freqüente, principalmente durante a adolescência. Mudanças de estilo de vida, como alimentação e atividade física, são fundamentais na sua prevenção e tratamento. Tratamento medicamentoso e, eventualmente, tratamento cirúrgico também devem ser considerados, dependendo da gravidade, mesmo nesta fase da vida.

The study analyzed the occurrence of hypoglycemia and metabolic control of two monitoring schemes in type-1 diabetic patients during 12 months they participated in education groups. Clinical crossed trials were conducted with 21 patients divided into two groups included the monitoring scheme proposed. Glycemic individuals' profiles directed monthly adjustments of insulin doses. The analyses were performed using Fisher, t-Student and Friedman's tests. There were no significant differences in hypoglycemia between the groups in any given month or scheme (p > 0.05). The comparisons within groups between insulin mean dose and HbA1c, and hypoglycemic episodes also did not show significant difference (p > 0.05). Metabolic control improved during the study in both groups, independently from the monitoring scheme (p < 0.05).

O estudo analisou a ocorrência de hipoglicemia e o controle metabólico na vigência de dois esquemas demonitorização glicêmica em pacientes com diabetes mellitus tipo1, durante 12 meses de participação em gruposeducativos. Trata-se de ensaio clínico cruzado, com 21 pacientes divididos em dois grupos. Os perfis glicêmicosindividuais nortearam ajustes mensais das doses de insulina. As análises foram realizadas pelos testes Fisher, t-Student e Friedman. A ocorrência de hipoglicemia entre os grupos não mostrou diferença em nenhum dos mesese esquemas vigentes (p>0,05). Comparações intragrupos, entre médias das quantidades de insulina e hemoglobinaglicada (HbA1c), com ocorrência de hipoglicemias também não evidenciou diferença significante (p>0,05).O controle metabólico melhorou nos dois grupos (p<0,05).

As sociedades modernas, especialmente aquelas que se encontram em transição para um estilo de vida ocidental, vem apresentando um aumento significativo da prevalência da obesidade, que em muitos locais apresentam características epidêmicas. Apesar de ser amplamentereconhecido o papel de fatores genéticos, a explosão da obesidadeobservada nos últimos cem anos não pode ser explicada por alterações gênicas que tenham ocorrido neste curto espaço de tempo, mas sim, pelas mudanças ocorridas no meio ambiente conseqüentes ao intenso processo de industrialização e aos avanços tecnológicos que ocorreram no mundo contemporâneo. As determinantesque levaram ao aumento ponderal corporal se relacionam basicamenteàs mudanças ambientais a que indivíduos geneticamente suscetíveis ao ganho de peso se expuseram, aumentando a ingestão calórica e de gorduras, reduzindo a atividade física frente ao estilo de vida característico da vida moderna. Baseado na maior disponibilidade e menor custo dos alimentos, na excessiva mecanização e automatização que tornam o indivíduo mais sedentário e na maior pressãopsicológica de natureza profissional e social, o homem moderno vem sofrendo uma significativa alteração de seu comportamento de natureza obesogênica, que será discutido no presente trabalho. Considerandoque a obesidade é universalmente reconhecida como um importante fator de risco para as doenças cardiovasculares e o diabetes, é necessária maior atenção do ponto de vista de saúde publica em não somente tratar, mas principalmente prevenir a obesidade modificando o ambiente tóxico com base em estratégias que promovam mudanças comportamentais ou que obtenham novas tecnologias alimentares.
