Abstract Introduction: The association of diabetes with subclinical thyroid diseases may increase the risk of cardiovascular diseases. We analyzed the association of subclinical hypothyroidism, diabetes, and both diseases with carotid Intima-Media Thickness (cIMT) as a surrogate maker for early cardiovascular disease in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Methods: Cross-sectional analysis with data from the 3rd visit (2017‒2019). Linear regression models were used to evaluate the association of subclinical hypothyroidism, diabetes and of both diseases with a cIMT presented as Beta (95% Confidence Interval – 95% CI) without adjustment, with adjustment for sociodemographic variables (Model 1) and multivariable adjustment (Model 1 more cardiovascular risk factors). We also used logistic regression models to analyze the Odds Ratio (OR) and 95% CI for the association of both diseases using cIMT > P75%. Results: After the exclusion of patients with previous cardiovascular disease, 5,077 participants with no diseases, 1578 with diabetes, 662 with subclinical hypothyroidism, and 234 with both diseases were included in the analysis. Linear regression models showed an association of cIMT with only diabetes (β = 0.019; 95% CI 0.012 to 0.027; p < 0.0001) and subclinical hypothyroidism more diabetes (β = 0.03; 95% CI 0.010‒0.047, p < 0.0001). The logistic regression model reported an association between diabetes and CIMT higher than P75% (OR = 1.49, 95% CI 1.30‒1.71). No interaction between diabetes and subclinical hypothyroidism was detected using cIMT respectively as a continuous (p = 0.29) or as a categorical variable (p = 0.92). Discussion: Diabetes was associated with higher cIMT values. However, no additive effect of subclinical hypothyroidism associated with diabetes over cIMT was detected.

ABSTRACT Objective: To determine the relationship between psoriasis, thyroid-stimulating hormone (TSH), free thyroxine (FT4), free triodothyronine (FT3), thyroid peroxidase antibodies (TPOAb), and subclinical thyroid dysfunctions in middle-aged and older adults. Materials and methods: Cross-sectional analyses included a self-reported medical diagnosis of psoriasis and thyroid function from the 3rd visit (2017-2019) of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). TSH, FT4, and FT3 levels were analyzed as continuous variables and quintiles, and TPOAb positivity and subclinical hypothyroidism as a yes/no variable. Logistic regression models were built as crude and adjusted by main confounders (age, sex, education level, race/ethnicity, and smoking). Results: From 9,649 participants (52.3% women; 59.2 ± 8.7 years old), the prevalence of psoriasis was 2.8% (n = 270). TSH, FT4, TPOAb positivity, and subclinical hypothyroidism were not associated with psoriasis in the main analyses. In the stratified analysis, our findings showed positive associations of the lowest (OR = 2.01; 95% CI 1.05-3.84; p = 0.036) and the highest (OR = 2.13; 95% CI 1.12-4.05; p = 0.022) quintiles of FT4 and a protective association of TPOAb positivity (OR = 0.43; 95% CI 0.19-0.98; p = 0.046) with prevalent psoriasis in women. In the logistic regression for FT3, participants in the 1st quintile showed a statistically significant association with psoriasis for the whole sample (OR = 1.66; 95% CI 1.11-2.46; p = 0.013) and for men (OR = 2.25; 95% CI 1.25-4.04; p = 0.007) in the sex-stratified analysis. Conclusions: The present study showed that the association of FT4 levels with psoriasis are different according to sex, with a possible U-shaped curve in women but not in men. Although there were some associations of FT3 with psoriasis, they may be a consequence of non-thyroidal illness syndrome. Further prospective data may clarify the association of thyroid function and psoriasis.

ABSTRACT Objective: Pregnant women with type 1 diabetes (T1D) have an increased risk of maternal-fetal complications. Regarding treatment, continuous subcutaneous insulin infusion (CSII) has advantages compared to multiple daily injections (MDI), but data about the best option during pregnancy are limited. This study's aim was to compare maternal-fetal outcomes among T1D patients treated with CSII or MDI during pregnancy. Subjects and methods: This study evaluated 174 pregnancies of T1D patients. Variables of interest were compared between the groups (CSII versus MDI), and logistic regression analysis was performed (p < 0.05). Results: Of the 174 included pregnancies, CSII was used in 21.3% (37) and MDI were used in 78.7% (137). HbA1c values improved throughout gestation in both groups, with no difference in the first and third trimesters. The frequency of cesarean section was significantly higher in the CSII group [94.1 vs. 75.4%, p = 0.017], but there was no significant difference in the frequency of other complications, such as miscarriage, premature delivery and preeclampsia. The mean birth weight and occurrence of neonatal complications were also similar, except for the proportion of congenital malformations, which was significantly lower in the CSII group [2.9 vs. 15.6%, p = 0.048]. In regression analysis, the association of CSII with cesarean section and malformations lost significance after adjusting for HbA1c and other covariates of interest. Conclusion: In this study, we observed a higher frequency of cesarean section and a lower occurrence of congenital malformations in the CSII group, but the adjusted results might indicate that these associations are influenced by glycemic control.

ABSTRACT Objective: To evaluate the association of neck circumference (NC) with gestational diabetes (GDM) and adverse outcomes in women with overweight and obesity. Subjects and methods: This prospective study included 132 (BMI > 25 kg/m2) pregnant women without and with GDM. Standardized questionnaire and biochemical/physical evaluation were performed during the 1st to 3rd trimester. Fifth-five women were evaluated regarding hypertension in pregnancy, type of delivery and neonatal complications (death, intensive care unit admission and hypoglycemia). Results: Women with (n = 61) and without (n = 71) GDM had similar mean (SD) pre-gestational BMI [30.3 (4.0) vs. 29.4 (3.5) kg/m2, p = 0.16]. Women with GDM were older [32 (6) vs. 28 (6) yrs, p < 0.001] and had greater NC [36.0 (2.7) vs. 34.5 (1.8) cm, p < 0.001]. NC was similar in women with GDM diagnosed in first or third trimester [p = 0.4] and was correlated with FPG [r 0.29, p = 0.01] and systolic [r 0.28, p = 0.001] and diastolic [r 0.25, p = 0.004] blood pressure. NC was associated with GDM [OR 1.25, 95%CI 1.03-1.52] adjusted for age, physical activity, education and familiar history of diabetes. In ROC analysis, the area under the curve was 0.655 and the cut-off value of 34.5 cm had 0.70 of sensitivity and 0.51 of specificity for GDM. Women who had NC ≥ 34.5 vs. < 34.5 cm had higher frequencies of hypertension [32.3 vs. 4.2%, p = 0.01]. Conclusions: In a group of pregnant women with overweight or obesity, NC can be a useful tool for identifying risk of GDM and obstetric adverse outcomes.

ABSTRACT Objective: Although some previous data have suggested a high iodine intake in Brazil, the prevalence of antithyroperoxidase antibodies (TPOAb) in the country is compatible with rates from countries with adequate iodine intake. This observation emphasizes the importance of knowing the incidence of TPOAb in Brazil. Materials and methods: This prospective analysis included euthyroid participants with negative TPOAb at baseline and a thyroid function assessment at a 4-year follow-up. TPOAb was measured by electrochemiluminescence and considered positive when titers were ≥34 IU/mL. TSH and free T4 (FT4) levels were determined by a third-generation immunoenzymatic assay. The incidence of TPOAb is expressed in percentage per year or as a cumulative incidence within the 4-year follow-up period. Results: Of 8,922 euthyroid participants (mean age 51.1 years; 50.9% women) with a negative TPOAb test at baseline, 130 presented incident TPOAb at the 4-year follow-up, yielding an annual incidence of TPOAb of 0.38%/year (95% confidence interval [95% CI], 0.37-0.39%/year) and a cumulative incidence over 4 years of 1.46% (95% CI, 1.21-1.71%). In men, the annual incidence was 0.32% (95% CI, 0.31-0.33%), and the cumulative incidence over 4 years was 1.23% (95% CI, 0.90-1.56%). In women, the annual incidence was 0.43%/year (95% CI, 0.42-0.44%/year) and the cumulative incidence over 4 years was 1.67% (95% CI, 1.30-2.04%). The only factor associated with incident TPOAb was the occurrence of thyroid diseases at follow-up. No differences in TPOAb incidence were detected across ELSA-Brasil research centers. Conclusion: Based on the results of this study, the incidence of TPOAb per year and at a 4-year follow-up period are compatible with those of a country with adequate iodine intake.

ABSTRACT Objective This study aimed to compare the effects of two lifestyle intervention programs for type 2 diabetes mellitus (T2DM) prevention – traditional or interdisciplinary psychoeducation-based intervention – in daily habits and cardiometabolic risk factors and investigate the role of the psychoeducational approach for the retention of individuals in the program. Subjects and methods Between 2008 and 2010, in a public health service, 183 pre-diabetic individuals were allocated to two 18-month interventions involving diet and physical activity. Physical activity, diet, quality of life (QOL) and depression and biochemical measurements were obtained. Linear mixed-effect models were used to assess the effect of the interventions. A student t test was used to compare dropouts versus non-dropouts. Results Improvements in energy intake and physical activity were greater in the interdisciplinary than the traditional intervention. A decrease in fat mass and blood pressure was more pronounced with interdisciplinary intervention. Dropouts from the traditional intervention only had higher BMI and lower fiber intake and QOL than non-dropouts. Conclusion The interdisciplinary psychoeducation-based intervention revealed useful for reducing cardiometabolic risk and retaining individuals with worse health profiles. This approach represents a feasible strategy for motivating high-risk individuals to adopt a long-term healthy lifestyle.

ABSTRACT Objective Our aim was to describe the distribution of selected biomarkers according to age and sex, adjusted for HOMA-IR and adiposity, in a subset of middle-aged individuals of Brazilian Longitudinal Study of Adult Health-ELSA without diabetes mellitus or CVD. Subjects and methods This cross-sectional study was conducted in 998 participants of the ELSA-Brasil without diabetes and/or cardiovascular disease. In addition to the traditional risk factors, several biomarkers concentrations were compared according to sex, age groups (35-44; 45-54 yrs) and HOMA-IR tertiles. Linear regression was used to examine independent associations of sex and age with selected novel biomarkers, adjusted for body adiposity and HOMA-IR. Results Fifty-five percent were women. Men had higher mean values of body mass index, waist circumference, blood pressure, plasma glucose, HOMA-IR, worse lipid profile and higher E-selectin and lower leptin concentrations than women; while women had higher levels of HDL-cholesterol and leptin than men. Mean values of waist circumference, systolic BP, plasma glucose and apolipoprotein B (Apo B) increased with age in both sexes. Leptin and E-selectin concentrations increased across HOMA-IR tertiles. Independent associations of Apo B with age were found only in male sex, while of leptin with body mass index and HOMA-IR, and of E-selectin with HOMA-IR in both sexes. Conclusions In conclusion, our data indicate age, sex, adiposity and, consequently, insulin resistance, influence circulating levels of Apo B, leptin and E-selectin, suggesting that those aspects should be taken into consideration when assessing these parameters for research or clinical purposes in individuals at relatively low cardiometabolic risk.

There are numerous particles, enzymes, and mechanisms in the lipid metabolism that are involved in the genesis of cardiovascular disease (CVD). Given its prevalence in populations and its impact on mortality, it is relevant to review the lipid metabolism as it may potentially provide subsidies to better prediction. This article reviews the importance of traditional cardiovascular risk factors and comments on the potential of novel lipid biomarkers involved in the physiopathology of CVD. The Framingham cohorts proved the role of traditional risk factors (physical inactivity, smoking, blood pressure, total cholesterol, LDL-C, HDL-C, plasma glucose) in the prediction of cardiovascular events. However, a significant number of individuals that suffer from a cardiovascular event has few or none of these factors. Such finding indicates the need for new biomarkers able to identify plaques that are more susceptible to rupture. Some of bloodstream biomarkers related to lipid metabolism are modified LDL particles, apolipoprotein AI (apo AI), apolipoprotein B, lipoprotein (a) [Lp (a)], cholesteryl ester transfer protein (CETP), subtypes of LDL and HDL particles, and lipoprotein-associated phospholipase A2 (Lp-PLA2). These factors participate in the atherosclerotic process, and are abnormal in individuals at high risk, or in those who suffered from a cardiovascular event. Lp (a) determination is already employed in clinical practice and should be included as a reference parameter for CVD monitoring. Furthermore, there are expectations for wider use of apo B, non-HDL cholesterol and total cholesterol / HDL-C determination to improve cardiovascular risk assessment.

A microbiota intestinal, adquirida no período pós-natal, é composta por grande diversidade de bactérias que desempenham diferentes funções no hospedeiro humano, entre elas a absorção de nutrientes, proteção contra patógenos e modulação do sistema imune. O conteúdo bacteriano intestinal ainda não é totalmente conhecido, mas sabe-se que é influenciado por fatores internos e principalmente externos que modulam sua composição e função. Estudos indicam que a microbiota intestinal difere em indivíduos magros e obesos e ainda naqueles que mantêm hábitos alimentares diferentes. Há evidências de que as relações entre dieta, inflamação, resistência à insulina e risco cardiometabólico são em parte mediadas pela composição de bactérias intestinais. Conhecimentos sobre a microbiota poderão reverter em diferentes estratégias para manipular as populações bacterianas e promover saúde. Esta revisão aborda a relevância do conhecimento sobre o papel de fatores ou padrões alimentares na composição da microbiota, assim como mecanismos fisiopatológicos de doenças metabólicas crônicas e as potencialidades de prebióticos e probióticos sobre o perfil de risco cardiometabólico.

The gut microbiota obtained after birth is composed of a large range of bacteria that play different roles in the human host, such as nutrient uptake, protection against pathogens and immune modulation. The intestinal bacterial content is not completely known, but it is influenced by internal, and mainly by external factors, which modulate its composition and function. Studies indicate that the gut microbiota differs in lean and obese individuals, and in individuals with different food habits. There is evidence that the relationship between diet, inflammation, insulin resistance, and cardiometabolic risk are, in part, mediated by the composition of intestinal bacteria. Knowledge about the gut microbiota may result in different strategies to manipulate bacterial populations and promote health. This review discusses the relevance of understanding the role of dietary factors or patterns in the composition of the microbiota, as well as pathophysiological mechanisms of chronic metabolic diseases, and the potential of prebiotics and probiotics on the cardiometabolic risk profile.

Ocorreram reduções significativas na prevalência de glicemia de jejum alterada e tolerância à glicose diminuída após um ano de intervenção (de 58,4% para 35,4%, p < 0,001; e de 30,1% para 21,7%, p = 0,004, respectivamente). CONCLUSÕES: O programa de intervenção de um ano em hábitos de vida traz benefícios ao perfil de risco cardiometabólico em indivíduos nipobrasileiros de alto risco.

OBJECTIVE: To assess the effect of a health promotion program on cardiometabolic risk profile in Japanese-Brazilians. METHODS: A total of 466 subjects from a study on diabetes prevalence conducted in the city of Bauru, southeastern Brazil, in 2000 completed a 1-year intervention program (2005-2006) based on healthy diet counseling and physical activity. Changes in blood pressure and metabolic parameters in the 2005-2006 period were compared with annual changes in these same variables in the 2000-2005 period. RESULTS: During the intervention, there were greater annual reductions in mean (SD) waist circumference [-0.5(3.8) vs. 1.2(1.2) cm per year, p<0.001], systolic blood pressure [-4.6(17.9) vs. 1.8(4.3) mmHg per year, p<0.001], 2-hour plasma glucose [-1.2(2.1) vs. -0.2(0.6) mmol/L per year, p<0.001], LDL-cholesterol [-0.3(0.9) vs. -0.1(0.2) mmol/L per year, p<0.001] and Framingham coronary heart disease risk score [-0.25(3.03) vs. 0.11(0.66) per year, p=0.02] but not in triglycerides [0.2(1.6) vs. 0.1(0.42) mmol/L per year, p<0.001], and fasting insulin level [1.2(5.8) vs. -0.7(2.2) IU/mL per year, p<0.001] compared with the pre-intervention period. Significant reductions in the prevalence of impaired fasting glucose/impaired glucose tolerance and diabetes were seen during the intervention (from 58.4% to 35.4%, p<0.001; and from 30.1% to 21.7%, p= 0.004, respectively). CONCLUSIONS: A one-year community-based health promotion program brings cardiometabolic benefits in a high-risk population of Japanese-Brazilians.

Com o envelhecimento da população, as doenças crônicas serão mais prevalentes, como o diabetes melito (DM) e aquelas caracterizadas por disfunções cognitivas, como as demências. Alguns estudos mostraram associação do DM e outros fatores de risco cardiovascular associados a distúrbios cognitivos. Além das complicações vasculares, estudos sugerem ação da hiperglicemia e dos produtos avançados finais de glicação (PAFG) em estresse oxidativo e acúmulo de substância β-amilóide intracerebral. Outros fatores também vêm sendo investigados, como o papel da insulinemia, da genética e do IGF-1 (insulin-like growth factor-1). Estudos mostraram que o bom controle glicêmico e a ingestão de dieta rica em gordura poliinsaturada, ômega-3 ou alimentos antioxidantes podem ter papel protetor contra os déficits cognitivos. Esclarecimentos sobre a associação entre DM e cognição e sua fisiopatologia podem ser essenciais para a prevenção e o tratamento de déficits cognitivos, levando a impacto positivo sobre a qualidade de vida dos pacientes idosos com DM.

As the population getting older, the chronic diseases will be more prevalent as diabetes mellitus (DM) and diseases characterized by cognitive deficits, as dementia. Studies have already shown an association between DM and cardiovascular risk factors associated with cognitive impairment. Besides the vascular complications of DM, studies have proposed the role of hyperglycemia and advanced glycosilation end products (AGEP) causing oxidative stress and β-amiloid protein brain deposition. Other factors have also been investigated, such as the role of insulinemia, genetic and IGF-1 (insulin-like growth factor-1). Some studies showed that good glucose control and intake of poli-unsaturated fat, Ômega-3 or anti-oxidative food can play a protector role against cognitive deficits. Improving knowledge about the association between DM and cognition and its physiopathology, can be essential for the prevention and treatment of cognitive impairment, leading to a beneficial impact on the quality of life of elderly patients with DM.

A doença cardiovascular (DCV), incluindo a doença arterial coronariana (DAC), acidente vascular cerebral (AVC) e doença arterial periférica (DAP), é importante causa de morte em populações, especialmente na diabética. Indivíduos diabéticos apresentam risco aumentado de 3 a 4 vezes de sofrer evento cardiovascular e o dobro do risco de morrer deste evento quando comparados à população geral. Tem havido declínio na mortalidade por DCV, porém a queda nas mortes por DAC em portadores de diabetes tem sido bastante inferior à de não-diabéticos. Vários fatores presentes no diabetes favorecem a maior ocorrência de DCV, como a hiperglicemia, a resistência à insulina, além de fatores de risco clássicos e não-clássicos (hipertensão arterial sistêmica, dislipidemia, obesidade, estado inflamatório subclínico e outros). É possível que o potencial aterogênico da obesidade decorra em parte da produção aumentada de citocinas pelos adipócitos. Devido à marcante associação entre diabetes e DCV, e prognóstico desfavorável após um evento, é importante identificar quais são os indivíduos de mais alto risco e como rastreá-los. A American Heart Association e a American Diabetes Association recomendam estratificação do risco de pacientes sintomáticos por testes diagnósticos. O desafio está em identificar pacientes diabéticos assintomáticos que se beneficiariam de testes diagnósticos para detecção precoce de DCV, visando viabilizar medidas preventivas ou terapêuticas, capazes de reduzir morbi-mortalidade. O benefício do controle glicêmico e dos demais fatores de risco na prevenção de eventos CV no diabetes já documentado, justifica estabelecer estratégias que otimizem a identificação e possibilitem intervenções nos pacientes de alto risco, buscando reduzir mortalidade.

Cardiovascular disease, which includes coronary heart disease (CHD), cerebrovascular disease (CVD), and peripheral vascular disease (PVD), is the leading cause of mortality in populations, particularly in the diabetic one. Individuals with diabetes have at least a two-fold to four-fold increased risk of having cardiovascular events and a double risk of death compared with age-matched subjects without diabetes. A decline in mortality from CVD has been shown, but decline due to CHD is consistently lower in individuals with diabetes when compared with non-diabetics. The presence of several factors in diabetes leads to high occurrence of CVD such as hyperglicemia, insulin resistance, and classical and non-classical risk factors (systemic hypertension, dyslipidemia, obesity, proinflammatory condition and others). It is possible that the atherogenic role of obesity may be at least in part due to increased adipocyte production of cytokines. Considering the marked association of diabetes and CVD and unfavorable prognosis following an event, it is important to identify who is at high risk and how to screen. The American Heart Association and American Diabetes Association recommend risk stratification using diagnostic tests. However, the challenge is to accurately identify patients without a prior history of an event and those without symptoms strongly suggesting CVD, in whom additional testing would be indicated in order to achieve the most effective prevention. The benefits of glycemic control and the other risk factors have already been shown and justify optimization of the management of this high-risk population, aiming to reduce cardiovascular mortality disease and improve quality of life.
