ABSTRACT

Diabetic patients are at risk of developing unfavorably from SARS-COV19 disease, especially when they have poor glycemic control. On the other hand, in the case of diabetic patients with severe COVID, they evolve with severe hyperglycemia, often difficult to manage. Marked hyperglycemia has also been described in people without a known history of previous diabetes, even there have been reported cases of insulin-dependent diabetes debut in days after the disease. The aim of this review is to analyze possible mechanisms involved in the relationship between COVID-19 and DIABETES.

ABSTRACT

Introducción: La diabetes mellitus se considera un síndrome heterogéneo con etiología compleja en el que influyen factores genéticos y ambientales. Objetivo: Identificar la presencia de alteraciones del metabolismo glucídico y factores de riesgo aterogénicos en familiares de primera línea de pacientes diabéticos tipo 2. Métodos: Se realizó un estudio descriptivo de corte transversal que incluyó a 120 pacientes adultos, hijos de pacientes diabéticos, en los que no se encontraban antecedentes de alteraciones del metabolismo glucídico, pertenecientes al Policlínico Universitario Héroes del Moncada, del municipio Plaza de la Revolución. Se estudiaron variables sociodemográficas, variables clínicas y relacionadas con los estilos de vida como la tensión arterial, el índice de masa corporal, colesterol, triglicéridos, glucemias (ayunas y posprandial), hábito de fumar, actividad física y hábitos dietéticos. Resultados: Los pacientes tenían una edad promedio de 54,42 años y predominó el sexo femenino. Se detectaron alteraciones del metabolismo glucídico en 28,3 por ciento de los cuales 23,3 por ciento se consideraron prediabéticos y 5 por ciento diabéticos. Los factores de riesgo que predominaron fueron la dieta inadecuada, obesidad abdominal, hipercolesterolemia e hipertrigliceridemia que fueron más evidentes en los pacientes diagnosticados como diabéticos. Conclusiones: Los familiares de primer grado de pacientes diabéticos pueden presentar una alta prevalencia de alteraciones del metabolismo glucídico y factores de riesgo aterogénicos, aún sin sintomatología evidente, lo que refuerza la necesidad de realizar un diagnóstico temprano para evitar la progresión de la enfermedad(AU)


Introduction: Diabetes mellitus is considered a heterogeneous syndrome with a complex etiology, influenced by genetic and environmental factors. Objective: To identify the presence of alterations of the glucidic metabolism and atherogenic risk factors in first- degree relatives of type 2 diabetic patients. Methods: A descriptive cross-sectional study was carried out at Heroes del Moncada University Polyclinic, in Plaza de la Revolution municipality. The study included 120 adult patients, descendants of diabetic patients. They had no history of alterations of the glucidic metabolism. Sociodemographic, clinical variables were studied, and those related to lifestyles such as blood pressure, body mass index, cholesterol, triglycerides, (fasting and postprandial) glycaemia, smoking, physical activity and dietary habits. Results: These patients had average age of 54.42 years and the female sex predominated. Alterations of the glucidic metabolism were detected in 28.3 percent, 23.3 percent of them were considered pre-diabetic and 5 percent diabetic. The predominant risk factors were inadequate diet, abdominal obesity, hypercholesterolemia, and hypertriglyceridemia, which was much evident in patients diagnosed as diabetic. Conclusions: The first-degree relatives of diabetic patients may present high prevalence of alterations of glucidic metabolism and atherogenic risk factors, even with no evident symptoms, which reinforces the need of early diagnosis to avoid the progression of the disease(AU)

ABSTRACT

RESUMO Objetivo: avaliar as diferenças no perfil metabonômico de pacientes que atingiram remissão de diabetes mellitus tipo 2 (DM2) após cirurgia bariátrica em relação aos que apresentaram manutenção ou recidiva dessa condição após a cirurgia. Métodos: Participaram do estudo 33 pacientes obesos diabéticos tipo 2, dos quais 22 tiveram remissão completa da DM2 e 11 tiveram recidiva da DM2 ou não apresentaram remissão da doença no pós-operatório. Amostras de sangue foram coletadas para avaliação dos perfis metabonômicos séricos através de um estudo metabonômico baseado em RMN de 1H. Resultados: o modelo metabonômico para avaliação da recidiva da diabetes apresentou uma acurácia de 93,9%, sensibilidade de 81,8%, especificidade de 100%, valor preditivo positivo (VPP) igual a 100% e valor preditivo negativo (VPN) igual a 91,7%. Conclusão: a cirurgia bariátrica promove efeitos específicos na distribuição dos metabólitos de pacientes que atingiram remissão de DM2, e essa nova distribuição pode ser avaliada através de um modelo metabonômico.


ABSTRACT Purpose: To evaluate the differences in the metabonomic profile of patients who achieved remisison of Type 2 diabetes mellitus (T2DM) after bariatric surgery in relation to those who presented maintenance or recurrence of this condition after surgery. Methods: Thirthy-three patients with obesity and T2D were submitted to bariatric/metabolic surgery, among which, 22 experienced complete remission of T2D, and 11 did not experience remission in the postoperative period. Blood samples were taken in order to assess the serum profiles through a 1H NMR-based metabonomic study. Results: The metabonomic model for the assessment of T2D recurrence presented an accuracy of 93.9%, sensibility of 81.8%, specificity of 100%, positive predictive value of 100% and a negative predictive value of 91.7%. Conclusion: bariatric surgery provide specific effects on the distribution of metabolites in those patients who achieved remission of T2DM, and this new distribution can be assessed through a metabonomic model.

ABSTRACT

The consumption of alcoholic beverages influences carbohydrate and lipid metabolism, although it is not yet clear whether metabolism during physical exercise at different intensities is also affected. This was the objective of the present study. Eight young and healthy volunteers performed a treadmill test to identify the running speed corresponding to a lactate concentration of 4 mM (S4mM). At least 48 h later, they were subjected to two experimental trials (non-alcohol or alcohol) in which they performed two 1-km running sessions at the following intensities: 1) S4mM; 2) 15% above S4mM. In both trials, blood lactate, triglycerides, and glucose concentrations were measured before and after exercise. The acute alcohol intake increased triglycerides, but not lactate concentration under resting conditions. Interestingly, alcohol intake enhanced the exercise-induced increase in lactate concentration at the two intensities: S4mM (non-alcohol: 4.2±0.3 mM vs alcohol: 4.8±0.9 mM; P=0.003) and 15% above S4mM trial (P=0.004). When volunteers ingested alcohol, triglycerides concentration remained increased after treadmill running (e.g., at S4mM - at rest; non-alcohol: 0.2±0.5 mM vs alcohol: 1.3±1.3 mM; P=0.048). In contrast, glucose concentration was not modified by either alcohol intake, exercise, or their combination. We concluded that an acute alcohol intake changed lactate and lipid metabolism without affecting blood glucose concentration. In addition, the increase in lactate concentration caused by alcohol was specifically observed when individuals exercised, whereas augmented triglycerides concentration was already observed before exercise and was sustained thereafter.

ABSTRACT

Introdução: A associação entre perda auditiva e Diabetes Mellitus tipo 1 (DM1) é ainda pouco estudada. A perda auditiva é uma das complicações crônicas relacionadas ao grau de controle glicêmico, que os pacientes podem apresentar com a progressão da doença. Objetivo: Investigar o comprometimento auditivo por meio das emissões otoacústicas transitórias (EOAT) por banda de frequência em adolescentes com DM1 e relação com o controle glicêmico. Métodos: Foram incluídos 80 adolescentes, 50% do gênero masculino, entre 10 e 19 anos de idade: 40 com DM1 e 40 controles saudáveis, pareados por gênero e idade. Os dados clínicos e laboratoriais foram pesquisados nos prontuários médicos. O controle glicêmico foi avaliado por meio dos exames de hemoglobina glicada e os pacientes com DM1 analisados de acordo com o controle glicêmico. A avaliação auditiva foi realizada por meio da imitanciometria, audiometria, e posteriormente EOAT, em sala tratada acusticamente, pelo protocolo "TE Test" de clique não-linear (1 KHz a 4 kHz) a 80 dB NPS de intensidade (AuDX - Biologic). Resultados: As respostas às EOAT foram ausentes em 5,12% em pacientes com DM1, com diferença significativa em relação aos controles (p=0,04). A análise das EOAT por bandas de frequência mostrou maior proporção de alteração nos adolescentes com DM1 mal controlados quando comparados aos bem controlados, nas frequências de 1000Hz, 2000Hz e 3000Hz (p<0,05). Conclusão: As EOAT por bandas de frequência permitiram a identificação precoce de comprometimento auditivo em adolescentes com DM1 e mostraram associação entre DM1 mal controlado e perda auditiva. (AU)


Introduction: The association between hearing loss and type 1 diabetes mellitus (DM1) is still poorly studied. Hearing loss is one of the chronic complications related to the degree of glycemic control that patients may present with the progression of the disease. Objective: To investigate auditory impairment through transient otoacoustic emissions (TEOAE) by frequency band in adolescents with DM1 and in relation to glycemic control. Methods: Were included 80 adolescents, 50% males, between 10 and 19 years of age: 40 with DM1 and 40 healthy controls, matched by gender and age. Clinical and laboratory data were taken from the medical records. Glycemic control was evalueted by glycated hemoglobin and the patients with DM1 were analyzed according to glycemic control. To the auditory evaluation were used the immittance and audiometry, and the TEOAE. The test was performed in the acoustically treated room, the non-linear TE test protocol (1 KHz to 4 kHz) at 80 dB SPL (AuDX - Biologic ). Results: TEOAE responses were absent in 5.12% of patients with DM1, with a significant difference in relation to controls (p = 0.04). The analysis of TEOAE by frequency bands showed a higher proportion of alteration in adolescents with DM1 poorly controlled when compared to well controlled ones, in the frequencies of 1000Hz, 2000Hz and 3000Hz (p <0.05). Conclusion: TEOAE by frequency bands allowed the early identification of auditory impairment in adolescents with DM1 and showed an association between poorly controlled DM1 and hearing loss. (AU)

ABSTRACT

Objetivo: Relacionar a evolução do perfil lipídico, glicêmico e pressórico de prematuro do nascimento aos 2 anos de idade corrigida com a classificação de peso ao nascer e sexo. Metodologia: Estudo longitudinal, amostra inicial de 71 prematuros, destes, 31 completaram o acompanhamento ambulatorial. Avaliados ao nascer, alta, 6 meses e 2 anos de idade corrigida (peso, idade gestacional, perfil lipídico, glicêmico, pressão arterial). Resultados: Glicemia, colesterol total, pressão arterial e triglicerídeos, não foram estatisticamente significantes em relação ao peso ao nascer e ao longo do seguimento. Colesterol total (p=0,18) e glicemia sofreram efeito de interação com o sexo. Pressão arterial acima do esperado aos 2 anos. Crescimento foi uniforme independente do sexo. Conclusão: O perfil lipídico, glicêmico e pressórico dos prematuros ao longo do acompanhamento não foi influenciado pela classificação de peso ao nascer. O sexo influenciou as concentrações de colesterol e a glicemia.


Objective: To relate the evolution of the lipid, glycemic and blood pressure profile of premature infants from birth to 2 years corrected age with the classification of birth weight and sex. Methodology: Longitudinal study, initial sample of 71 premature infants, of which 31 completed outpatient follow-up. Evaluated at birth, discharge, 6 months and 2 years corrected age (weight, gestational age, lipid, glycemic, blood pressure profile). Results: Blood glucose, total cholesterol, blood pressure and triglycerides were not statistically significant in relation to birth weight nor throughout follow-up. Total cholesterol (p=0.18) and blood glucose underwent interaction with sex. Blood pressure was higher than expected at 2 years old. Growth was uniform regardless of sex. Conclusion: The lipid, glycemic and blood pressure profile of premature infants during follow-up was not influenced by the birth weight classification. The cholesterol and blood glucose concentrations were influenced by sex.

ABSTRACT

Abstract Objective The present study aims to understand to what extent obesity is related to adversematernal, obstetrical, and neonatal outcomes in a Portuguese obstetrical population. Methods A retrospective case-control study was conducted at the Department of Obstetrics of a differentiated perinatal care facility. The study compared 1,183 obese pregnant womenwith 5,399 normal or underweight pregnantwomen for the occurrence of gestational diabetes, hypertensive pregnancy disorders, and preterm birth. Mode of delivery, birthweight, and neonatal intensive care unit (ICU) admissionswere also evaluated. Mean blood glucose values were evaluated and compared between groups, in the first and second trimesters of pregnancy. Only singleton pregnancies were considered. Results The prevalence of obesity was 13.6%. Obese pregnant women were significantly more likely to have cesarean sections (adjusted odds ratio [aOR] 2.0, p< 0.001), gestational diabetes (aOR 2.14, p< 0.001), hypertensive pregnancy disorders (aOR 3.43, p< 0.001), and large-for-gestational age ormacrosomic infants (aOR 2.13, p< 0.001), and less likely to have small-for-gestational age newborns (aOR 0.51, p< 0.009). No significant differences were found in terms of pretermbirths, fetal/neonatal deaths, low birthweight newborns, and neonatal ICU admissions among cases and controls. Maternal obesity was significantly associated with higher mean blood glucose levels, in the first and second trimesters of pregnancy. Conclusion Obesity is associated with increased risks of adverse pregnancy and neonatal outcomes. These risks seem to increase progressively with increasing body mass index (BMI) class. Female obesity should be considered a major public health issue and has consequences on maternal-fetal health.


Resumo Objetivo O presente estudo pretende avaliar em que medida a obesidade influencia os desfechos maternos, obstétricos e neonatais em uma população obstétrica portuguesa. Métodos Um estudo caso-controle retrospectivo foi realizado no departamento de obstetrícia de um centro perinatal diferenciado. O estudo comparou 1.183 grávidas obesas com 5.399 grávidas normoponderais ou com baixo peso para a ocorrência de diabetes gestacional, doenças hipertensivas da gravidez e parto pré-termo. Via de parto, peso ao nascimento e admissão na unidade de cuidados neonatais também foram avaliados. Os valores glicêmicos médios foram avaliados e comparados entre os dois grupos, no primeiro e segundo trimestres de gravidez. Apenas as gravidezes unifetais foram avaliadas. Resultados A prevalência da obesidade foi de 13.6%. As grávidas obesas tiveramrisco significativamente superior a ter uma cesariana (odds ratio ajustado [Ora] 2.0, p < 0.001), diabetes gestacional (ORa 2.14, p < 0.001), doenças hipertensivas da gravidez (ORa 3.43, p < 0.001), recém-nascidos grandes para a idade gestacional ou macrossômicos (ORa 2.13, p < 0.001) e menor probabilidade de ter recém-nascidos pequenos para a idade gestacional (ORa 0.51, p < 0.009). Não houve diferença estatisticamente significativa quanto aos partos pré-termo, mortes fetais/neonatais, baixo peso ao nascer e admissão à unidade de cuidados intensivos neonatais. O odds ratio foi ajustado para a idade, número de gestações, paridade, ganho ponderal, doenças hipertensivas da gravidez e diabetes gestacional. A obesidade materna esteve significativamente associada a valores glicêmicos médios superiores, no primeiro e segundo trimestres de gravidez. Conclusão A obesidade está associada a maior risco de desfechos adversos na gravidez e neonatais. Este risco parece aumentar progressivamente com o aumento do índice de massa corporal (IMC). A obesidade feminina deve ser considerada um importante problema de saúde pública e que tem repercussões na saúde maternofetal.

ABSTRACT

Abstract Objective To evaluate the factors associated with the need for insulin as a complementary treatment to metformin in pregnant women with gestational diabetes mellitus (GDM). Methods A case-control study was performed from April 2011 to February 2016 with pregnant women with GDM who needed complementary treatments besides diet and physical exercise. Those treated with metformin were compared with those who, in addition to metformin, also needed the combination with insulin. Maternal characteristics and glycemic control were evaluated. Multinomial logistic regression models were developed to evaluate the influence of different therapies on neonatal outcomes. Results A total of 475 pregnant women who needed pharmacological therapy were evaluated. Of these, 366 (77.05%) were submitted to single therapy with metformin, and 109 (22.94%) needed insulin as a complementary treatment. In the analysis of the odds ratio (OR), fasting glucose (FG)<90 mg/dL reduced the odds of needing the combination (OR: 0.438 [0.235-0.815]; p=0.009], as well as primiparity (OR: 0.280 [0.111-0.704]; p=0.007]. In obese pregnant women, an increased chance of needing the combination was observed (OR: 2,072 [1,063-4,039]; p=0,032). Conclusion Obesity resulted in an increased chance of the mother needing insulin as a complementary treatment to metformin, while FG<90 mg/dL and primiparity were protective factors.


Resumo Objetivo Avaliar os fatores associados à necessidade de insulina como tratamento complementar à metformina em gestantes com diabetes mellitus gestacional (DMG). Métodos Um estudo caso-controle foi realizado de abril de 2011 a fevereiro de 2016 comgestantes portadoras de DMG que necessitaram de tratamentos complementares além de dieta e exercícios físicos. Aquelas tratadas commetformina foram comparadas com aquelas que, além da metformina, também precisaram de combinação com insulina. Foram avaliadas as características maternas e de controle glicêmico. Modelos de regressão logística multinomial foram construídos para avaliar a influência das diferentes terapias nos desfechos neonatais. Resultados Foram avaliadas 475 gestantes que necessitaram de terapia farmacológica. Destas, 366 (77,05%) utilizaram terapia única com metformina, e 109 (22,95%) necessitaram de insulina como tratamento complementar. Na análise da razão de possibilidades (RP), a glicemia de jejum (GJ)<90mg/dL reduziu as chances de necessidade da combinação (RP: 0,438 [0,235-0,815]; p=0,009), bem como a primiparidade (RP: 0,280 [0,111-0,704]; p=0,007). Em gestantes obesas, foi observada uma chance maior de necessidade da combinação (RP: 2.072 [1.063-4.039]; p=0,032). Conclusão A obesidade resultou em um aumento na chance de a mãe precisar de insulina como tratamento complementar à metformina, enquanto a GJ<90 mg/dL e a primiparidade foram fatores de proteção.

ABSTRACT

ABSTRACT BACKGROUND: Obese adolescents are at higher risk of development of cardiovascular risk factors and obesity in later life. Dietary intake of antioxidants, particularly curcumin, as an active ingredient of turmeric extract, may have noticeable effects on obesity and its important complications such as cardiovascular risk factors. Therefore, the aim of this study was to assess the effects of curcumin supplementation on cardiovascular risk factors among overweight and obese female adolescents. DESIGN AND SETTING: Randomized placebo-controlled clinical trial; Pediatric Cardiovascular Research Center, Isfahan, Iran. METHODS: 60 adolescent girls (aged 13-18 years) were randomly assigned to receive either placebo or intervention. The adolescents were asked to consume one 500 mg tablet per day, containing either standardized 95% turmeric extract or placebo, and to undergo a weight maintenance or a mild weight loss diet for 10 weeks. Anthropometric and biochemical indices were assessed at the baseline and the end of the intervention. RESULTS: Curcumin supplementation had beneficial effects on body mass index (P = 0.019), waist circumference (P = 0.008), hip circumference (P = 0.030), high-density lipoprotein levels (P = 0.042) and triglyceride/high-density lipoprotein ratio (P = 0.021). However, in univariate analysis of covariance, no significant differences were found between the intervention and placebo groups after 10 weeks of supplementation (P > 0.05). CONCLUSIONS: Prescription of curcumin supplementation along with use of a slight weight loss diet might have beneficial effects on some cardiovascular risk factors among overweight and obese female adolescents. Larger clinical trials with higher curcumin doses and longer duration are needed to confirm the results from the current study. CLINICAL TRIAL REGISTRATION: IRCT20171107037302N1

ABSTRACT

Resumo O objetivo deste estudo foi determinar e comparar a magnitude da associação entre indicadores antropométricos com fatores de risco cardiometabólico em idosos. Trata-se de estudo transversal com 402 idosos atendidos pela Estratégia Saúde da Família no município de Viçosa-MG. Os fatores de risco considerados foram o excesso de gordura corporal, hipertensão arterial, alteração da glicemia e dos lipídeos séricos. A associação entre o índice de conicidade (IC) e a relação cintura/estatura (RCE) com os fatores de risco cardiometabólico foi avaliada pela análise de regressão linear múltipla. A amostra foi composta por 60,4% de mulheres e 36,3% de idosos com excesso de peso. O índice de conicidade e a relação cintura/estatura estiveram elevados em 57,2% e 88,1% dos idosos, respectivamente. Os resultados demonstraram que o aumento da gordura corporal, da pressão arterial diastólica, dos triglicerídeos, da glicemia e a redução do HDL-colesterol estão relacionados a maiores valores dos índices antropométricos avaliados. No entanto, a relação cintura/estatura apresentou maior magnitude de associação com os fatores de risco cardiometabólico do que o índice de conicidade.


Abstract The purpose of this study was to determine and compare a magnitude of the association between anthropometric indicators with risk of cardiometabolic risk in the elderly. This is a cross-sectional study with 402 elderly people attended by the Family Health Strategy in the city of Viçosa-MG. Risk factors for excess body fat, hypertension, blood glucose and serum lipid changes. An association between conicity index (CI) and waist-to-height ratio (WtHR) with cardiometabolic risk factors was assessed by multiple linear regression analysis. Sample was composed of 60.4% of women and 36.3% of overweight elderly. The connectivity index and a waist-to-height ratio were higher in 57.2% and 88.1% in the elderly, respectively. The results showed that the increase in body fat, diastolic blood pressure, triglycerides, glycemia and reduction of HDL-cholesterol are related to higher values of anthropometric indices evaluated. However, the waist-to-height ratio presented a greater magnitude of association with the cardiometabolic risk factors than the connectivity index.

ABSTRACT

ABSTRACT Objective We investigated the utility of maternal fetuin-A, N-terminal proatrial natriuretic peptide (pro-ANP), high-sensitivity C-reactive protein (hs-CRP), and fasting glucose levels at 11-14 gestation weeks for predicting pregnancies complicated by gestational diabetes mellitus (GDM). Subjects and methods This prospective cohort study included 327 low-risk pregnant women who completed antenatal follow-up at a tertiary research hospital between January and April 2014. Maternal blood samples were collected between 11-14 gestational weeks in the first trimester of pregnancy and then stored at -80 °C until further analyses. During follow-up, 29 (8.8%) women developed GDM. The study population was compared 1:2 with age- and body mass index-matched pregnant women who did not develop GDM (n = 59). Fasting plasma glucose (FPG) levels and serum fetuin-A, pro-ANP, and hs-CRP levels were measured using automated immunoassay systems. Results There was a significant negative correlation between fetuin-A and hs-CRP (CC = -0.21, p = 0.047) and a positive correlation between FPG and hs-CRP (CC = 0.251, p = 0.018). The areas under the receiver operating characteristic curve for diagnosing GDM were 0.337 (p = 0.013), 0.702 (p = 0.002), and 0.738 (p < 0.001) for fetuin-A, hs-CRP, and FPG, respectively. The optimal cut-off values were > 4.65, < 166, and > 88.5 mg/dL for maternal hs-CRP, fetuin-A, and FPG, respectively. Conclusion Reduced fetuin-A, elevated hs-CRP, and FPG levels in women in the first trimester can be used for the early detection of GDM. Further research is needed before accepting these biomarkers as valid screening tests for GDM.

ABSTRACT

ABSTRACT BACKGROUND: The influence of the placement of a band on the outcomes of one anastomosis gastric bypass (OAGB) has not been appropriately studied yet. OBJECTIVE: To compare early weight loss and glucose metabolism parameters following banded versus non-banded OAGB. METHODS: A prospective randomized study, which evaluated 20 morbidly obese individuals who underwent banded and non-banded OAGB and were followed-up for three months. Weight loss (percentage of excess weight loss - %EWL and percentage of body mass index loss - %BMIL) and glucose metabolism outcomes (glucose, insulin and homeostasis model assessment - HOMA) were compared. RESULTS: The banded group presented a significantly higher %EWL at one month (29.6±5.5% vs 17.2±3.4%; P<0.0001) and two months post-surgery (46±7% vs 34.2±9%; P=0.004544), as well as a significantly higher %BMIL at one month (9.7±1.1% vs 5.8±0.8%; P<0.0001), two months (15±1.4% vs 11.5±2.1; P=0.000248), and three months (18.8±1.8% vs 15.7±3.2%; P=0.016637). At three months, banded OAGB led to significant decreases of insulin (14.4±4.3 vs 7.6±1.9; P=0.00044) and HOMA (3.1±1.1 vs 1.5±0.4; P=0.00044), whereas non-banded OAGB also led to significant decreases of insulin (14.8±7.6 vs 7.8±3.1; P=0.006) and HOMA (3.2±1.9 vs 1.6±0.8; P=0.0041). The percent variation of HOMA did not significantly differ between banded and non-banded OAGB (P=0.62414); overall, the percent variation of HOMA was not correlated with %EWL (P=0.96988) or %BMIL (P=0.82299). CONCLUSION: Banded OAGB led to a higher early weight loss than the standard technique. Banded and non-banded OAGB led to improvements in insulin resistance regardless of weight loss.


RESUMO CONTEXTO: A influência da colocação de bandas sobre os resultados do bypass gástrico de anastomose única (BGAU) não foi profundamente estudada. OBJETIVO: Comparar a perda precoce de peso e os parâmetros do metabolismo da glicose após bypass gástrico de anastomose única (BGAU) com e sem anel. MÉTODOS: Estudo prospectivo randomizado que avaliou 20 obesos mórbidos submetidos ao BGAU com e sem anel e acompanhados por três meses. A perda de peso (percentual de perda do excesso de peso - %PEP e percentual de perda de peso - %PP) e parâmetros do metabolismo da glicose (glicemia, insulina e modelo homeostático de avaliação - HOMA) foram comparados. RESULTADOS: O grupo com anel apresentou %PEP significativamente maior em um mês (29,6±5,5% vs 17,2±3,4%; P<0,0001) e dois meses após a cirurgia (46±7% vs 34,2±9%; P=0,004544), bem como %PP significativamente maior em um mês (9,7±1,1% vs 5,8±0,8%; P<0,0001), dois meses (15±1,4% vs 11,5±2,1; P=0,000248) e três meses (18,8±1,8% vs 15,7±3,2%; P=0,016637). Aos três meses, o BGAU com anel resultou em reduções significativas de insulina (14,4±4,3 vs 7,6±1,9; P=0,00044) e HOMA (3,1±1,1 vs 1,5±0,4; P=0,00044), enquanto o BGAU sem anel também levou a reduções significativas de insulina (14,8±7,6 vs 7,8±3,1; P=0,006) e HOMA (3,2±1,9 vs 1,6±0,8; P=0,0041). A variação percentual de HOMA não diferiu significativamente entre BGAU com bandas ou sem anel (P=0,62414); no geral, a variação percentual do HOMA não foi correlacionada com %PEP (P=0,96988) ou %PP (P=0,82299). CONCLUSÃO: O BGAU com anel levou a uma maior perda de peso precoce do que a técnica padrão. O BGAU com ou sem anel levou à melhora precoce na resistência à insulina, independentemente da perda de peso.

ABSTRACT

Resumo Investigar os fatores associados ao controle glicêmico de pessoas com diabetes mellitus (DM). Estudo transversal realizado com 746 pessoas com DM tipo 2 e 40 anos ou mais de idade. Elegeu-se as seguintes variáveis: socioeconômicas, dados clínicos, estilo de vida e o risco para o desenvolvimento de úlceras nos pés. A coleta dos dados ocorreu por meio de entrevista, análise do prontuário e exame clínico dos membros inferiores. Utilizou-se o modelo de regressão múltipla de Poisson para determinação das razões de prevalência (RP) brutas e ajustadas da alteração do exame de hemoglobina glicada (HbA1c), considerada como variável dependente desta pesquisa, sendo esta classificada como elevada quando o valor apresentava resultado superior a 7%. Identificou-se a elevação da HbA1c em 68,9% dos participantes e foi mais prevalente em indivíduos com idade entre 50 e 69 anos (RP = 1,38/IC95% = 1,09-1,75), os que faziam uso de insulina (RP = 1,35/IC95% = 1,24-1,47), obesos (RP = 1,14/IC95% = 1,03-1,25) e naqueles que possuíam risco de ulceração nos pés (RP = 1,14/IC95% = 1,09-1,28). Os indivíduos na faixa etária entre 50 e 69 anos, os que faziam uso de insulina, os obesos e os que possuíam risco de ulceração nos pés apresentaram maiores taxas de prevalência de alteração na hemoglobina glicada.


Abstract Investigate the factors associated with the glycemic control in people with diabetes mellitus (DM). Cross-sectional study with 746 people with type-2 DM of age 40 or older. The following variables were selected: socioeconomic, clinical data, lifestyle and the risk of developing foot ulcers. Data collection occurred through interviews, medical record analysis and clinical examination of the lower limbs. We used the Poisson multiple regression model to determine the crude and adjusted prevalence ratios (PR) of the glycemic alteration. The alteration in the glycated hemoglobin (HbA1c) test was considered as a dependent variable in this study, which has been classified as high when the result was higher than 7%. The alteration in HbA1c was present in 68.9% of the participants and was more prevalent in individuals aged between 50 and 69 (PR = 1.38/IC95% = 1.09-1.75), who were taking insulin (PR = 1.35/IC95% = 1.24-1.47), obese (PR = 1.14/IC95% = 1.03-1.25) and who had foot ulceration risk (PR = 1.14/IC95% = 1.09-1.28). Individuals aged between 50 and 69; the ones who used insulin; the obese ones; and those who had a risk of foot ulceration, presented higher prevalence rates of alteration in the glycated hemoglobin.

ABSTRACT

Abstract The aim was to compare the metabolic risk factors (MRF) between sex, age and socioeconomic status in a sample of adolescents from Curitiba, Brazil. A cross-sectional school-based study was conducted on 997 adolescents (429 boys) aged 12-17 years old from public schools. Total Cholesterol (TC), LDL-c, HDL-c, Triglycerides, Glycemia, Blood Pressure, waist circumference and body mass index were measured. Sex, age and socioeconomic status information was obtained using a questionnaire. Descriptive analyses, Fisher Exact and Chi-Square Tests were used to establish the sample's characteristics and the MRF comparison between variables. We found that 27.4% were classified as overweight/obese, almost half of them had TC and LDL-c classified as limitrophe/altered, with a difference between the sexes (p < 0.01), and that a higher percentage of altered values was seen among girls. The percentage of 3 and 4 or more MRF was 13.8% and 6.3%, respectively. In addition, 86.5% of the participants had at least one and 39.7% had at least two MRF. We conclude that there was a high percentage of overweight/obese, as well as a great number of subjects with altered TC and HDL-c. We also pointed out the large percentage of aggregated metabolic risk factors in both sexes. Strategies to reduce metabolic risk factors are required.


Resumo O objetivo do estudo foi comparar os fatores de risco metabólicos (FRM) entre sexo, idade e nível socioeconômico numa amostra de adolescentes de Curitiba, Brasil. O estudo transversal foi conduzido com 997 adolescentes da rede pública de ensino (429 meninos) com idade entre 12-17 anos. Coletaram-se dados de colesterol total (CT), LDL-c, HDL-c, triglicerídeos, glicemia, pressão arterial, circunferência de cintura e índice de massa corporal. Informações sobre sexo, idade e nível socioeconômico foram coletados por meio de um questionário. Foram utilizadas análises descritivas, teste exato de Fisher e Qui-quadrado. Observou-se que 27,4% foram classificados como sobrepeso/obeso, quase metade com CT e LDL-c limítrofes/alterados, com uma diferença entre os sexos (p < 0,01) e uma proporção maior entre as meninas. Verificou-se que as proporções de 3 e 4 ou mais FRM foram 13,8% e 6,3%, respectivamente. Adicionalmente, 86,5% e 39,7% dos adolescentes demonstraram ao menos um e dois FRM, respectivamente. Conclui-se que houve um elevado percentual de sobrepeso/obeso, assim como um grande número de sujeitos com CT e HDL-s alterados. Verificou-se um grande percentual de agregação de FRM em ambos os sexos. São necessárias estratégias para reduzir esses fatores de risco nessa fase da vida.

ABSTRACT

Introdução: A síndrome do ovário policístico (SOP) é uma disfunção hormonal que acomete mulheres em idade reprodutiva podendo causar infertilidade, alterações no ciclo menstrual, hirsutismo, presença de cistos nos ovários, amenorreia e distúrbios metabólicos. Dentre as alterações metabólicas, resistência à insulina (RI) está presente em 70,5% das brasileiras com SOP. Objetivo: Revisar sistematicamente a literatura para descrever os efeitos da suplementação de ômega-3 na RI em mulheres com SOP. Materiais e métodos: As buscas pela informação foram realizadas na base de dados PubMed e LILACS utilizando os descritores "síndrome do ovário policístico"; "ácidos graxos ômega-3" e "resistência à insulina", em português e inglês. Resultados: Foram encontrados sessenta estudos e após o crivo metodológico seis foram selecionados para compor esta revisão. Ao total dos ensaios clínicos incluídos nesta revisão, 326 mulheres com faixa etária correspondente a 18-45 anos foram avaliadas com variações de índice de massa corporal entre 25 e 45 kg/m2. A variação de tempo de acompanhamento entre os estudos foi de 2 a 6 meses. Discussão: Em todos os estudos incluídos nesta revisão, a homeostase da glicose sérica foi avaliada pelo índice HOMA. Apenas 1 estudo avaliou o índice quantitativo de verificação da sensibilidade à insulina (QUICK1); 2 estudos avaliaram hemoglobina glicada e índice de sensibilidade à insulina (ISI de Matsuda). A avaliação da insulinemia de jejum foi realizada em 4 estudos. Metade dos estudos incluídos suplementou os pacientes com 1.000 mg de ômega-3 ao dia, enquanto 25% dos estudos utilizou a dosagem de 2000 mg/dia 25% utilizou 4000 mg/dia. A maioria das pesquisas encontradas (67%) descreveu efeito positivo entre a suplementação de ômega-3 e melhora da RI de mulheres com SOP, utilizando os diferentes métodos de dosagem da homeostase da glicose sérica. Conclusão: Conclui-se que o consumo de ômega-3 pode ter efeito positivo sobre a RI.


Introduction: Polycystic ovarian syndrome (PCOS) is a hormonal dysfunction that affects women of childbearing age and can cause infertility, changes in the menstrual cycle, hirsutism, ovarian cysts, amenorrhea, and metabolic disorders. Among the metabolic changes insulin resistance (IR) is present in 70.5% of Brazilians with PCOS. Objective:To systematically review the literature to describe the effects of omega-3 supplementation on IR in women with PCOS. Materials and methods: Information searches were performed in the PubMed and LILACS database using the descriptors "polycystic ovarian syndrome"; "fatty acids omega-3" and "insulin resistance", in Portuguese and English. Results: Sixty studies were found and six were selected to compose this review. In the total of the clinical trials included in this review, 326 women aged 18-45 years were evaluated with variations in body mass index between 25 and 45 kg/m2. The variation in follow-up time between the studies was from 2 to 6 months. Discussion: In all studies included in this review, serum glucose homeostasis was assessed by the HOMA index. Only 1 study evaluated the quantitative index of insulin sensitivity (QUICK1); 2 studies evaluated glycated hemoglobin and insulin sensitivity index (Matsuda ISI). The evaluation of fasting insulinemia was performed in 4 studies. Half of the included studies supplemented patients with 1000 mg omega-3 daily, while 25% of the studies used the dosage of 2000 mg / day 25% used 4000 mg / day. Most of the researches (67%) described a positive effect between omega-3 supplementation and improvement of IR in women with PCOS, using the different dosing methods for serum glucose homeostasis. Conclusion: It is concluded that omega-3 consumption may have a positive effect on IR.

ABSTRACT

ABSTRACT Objective: The aim was to characterize blood glucose fluctuations in patients with fulminant type 1 diabetes (FT1DM) at the stable stage using continuous blood glucose monitoring systems (CGMSs). Subjects and methods: Ten patients with FT1DM and 20 patients with classic type 1 diabetes mellitus (T1DM) (the control group) were monitored using CGMSs for 72 hours. Results: The CGMS data showed that the mean blood glucose (MBG), the standard deviation of the blood glucose (SDBG), the mean amplitude glycemic excursions (MAGE), the blood glucose areas and the percentages of blood glucose levels below 13.9 mmol/L were similar between the two groups. However, the percentage of blood glucose levels below 3.9 mmol/L was significantly higher in the FT1DM group compared to the T1DM group (p < 0.05). The minimum (Min) blood glucose level in the FT1DM group was significantly lower than that of the T1DM group (p < 0.05). Patients with FT1DM had severe dysfunction of the islet beta cells and alpha cells compared to patients with T1DM, as indicated by lower C-peptide values and higher glucagon/C-peptide values. Conclusion: In conclusion, patients with FT1DM at the stable stage were more prone to hypoglycemic episodes as recorded by CGMSs, and they had a greater association with severe dysfunction of both the beta and alpha islet cells compared to patients with T1DM.

ABSTRACT

RESUMO Objetivos: Analisar a associação entre os níveis glicêmicos quando da admissão dos pacientes à unidade de terapia intensiva pediátrica e a mortalidade entre pacientes hospitalizados. Métodos: Estudo retrospectivo de coorte conduzido em pacientes de uma unidade de terapia intensiva, admitidos ao Instituto Nacional de Salud del Niño entre 2012 e 2013. Utilizou-se um modelo de regressão de Poisson com variância robusta para qualificar a associação. Foi feita avaliação do desempenho do exame diagnóstico, para descrever sensibilidade, especificidade, valor preditivo positivo, valor preditivo negativo e razão de verossimilhança para cada faixa de glicemia. Resultados: Incluíram-se no total 552 pacientes (idade mediana de 23 meses; faixa de variação entre 5 meses e 79,8 meses). O nível glicêmico médio quando da admissão foi de 121,3mg/dL (6,73mmol/L). Faleceram durante a hospitalização 92 (16,6%) pacientes. Na análise multivariada, encontraram-se associações significantes entre glicemia < 65mg/dL (3,61mmol/L) (RR: 2,01; IC95% 1,14 - 3,53), glicemia > 200mg/dL (> 11,1mmol/L) (RR: 2,91; IC95% 1,71 - 4,55), desnutrição (RR: 1,53, IC95% 1,04 - 2,25), ventilação mecânica (RR: 3,71, IC95% 1,17 - 11,76) e mortalidade durante a hospitalização. Ocorreram baixa sensibilidade (entre 17,39% e 39,13%) e alta especificidade (entre 49,13% e 91,74%) para diferentes níveis glicêmicos de corte. Conclusão: Ocorreu maior risco de óbito entre os pacientes que desenvolveram hipoglicemia e hiperglicemia por ocasião da admissão à unidade de terapia intensiva pediátrica. Certas faixas de glicemia (> 200mg/dL (> 11,1mmol/L) e < 65mg/dL (3,61mmol/L)) tiveram uma alta especificidade como preditores de óbito.


ABSTRACT Objectives: To analyze the association between glycemia levels upon pediatric intensive care unit admission and mortality in patients hospitalized. Methods: A retrospective cohort of pediatric intensive care unit patients admitted to the Instituto Nacional de Salud del Niño between 2012 and 2013. A Poisson regression model with robust variance was used to quantify the association. Diagnostic test performance evaluation was used to describe the sensitivity, specificity, positive predictive value, negative predictive value and likelihood ratios for each range of glycemia. Results: In total, 552 patients were included (median age 23 months, age range 5 months to 79.8 months). The mean glycemia level upon admission was 121.3mg/dL (6.73mmol/L). Ninety-two (16.6%) patients died during hospitalization. In multivariable analyses, significant associations were found between glycemia < 65mg/dL (3.61mmol/L) (RR: 2.01, 95%CI 1.14 - 3.53), glycemia > 200mg/dL (> 11.1mmol/L) (RR: 2.91, 95%CI 1.71 - 4.55), malnutrition (RR: 1.53, 95%CI 1.04 - 2.25), mechanical ventilation (RR: 3.71, 95%CI 1.17 - 11.76) and mortality at discharge. There was low sensitivity (between 17.39% and 39.13%) and high specificity (between 49.13% and 91.74%) for different glucose cut-off levels. Conclusion: There was an increased risk of death at discharge in patients who developed hypoglycemia and hyperglycemia upon admission to the pediatric intensive care unit. Certain glucose ranges (> 200mg/dL (> 11.1mmol/L) and < 65mg/dL (3.61mmol/L)) have high specificity as predictors of death at discharge.

ABSTRACT

Background: Childhood and adolescent obesity is a major public health problem in Chile. Aim: To characterize cardiometabolic risk factors in a population of schoolchildren from Carahue, Chile. Material and Methods: Cross-sectional assessment of 208 children aged 10.4 ± 1.0 years (106 women). A clinical evaluation was carried out including pubertal development according to Tanner and anthropometric parameters. A fasting blood sample was obtained to measure glucose, insulin and lipid profile. HOMA-IR and Quicki indices were calculated. Insulin resistance (IR) was established according to Burrows criteria and Barja criteria, previously proposed for the Chilean pediatric population. The metabolic syndrome (MetS) was established using the modified Cook criteria. Results: Thirty eight percent of children had overweight and 33.1% obesity. MetS was only observed in obese subjects and the frequency in this subgroup was 38%. The prevalence of IR was 51% according to the Burrows criteria and 19% according to Barja criteria. It was more common in participants who were overweight, obese or had abdominal obesity. Children with insulin resistance according to Barja criteria, had worse anthropometric measures than their counterparts without resistance. When Burrows criteria was used, no differences in anthropometric measures were observed between participants with or without resistance. The frequency of MetS was 26 and 18% in children with insulin resistance according to Barja and Burrows criteria, respectively. Insulin levels and insulin sensitivity indexes were positively correlated with anthropometric parameters. Conclusions: There was a high prevalence of overweight, obesity and MetS in these participants. Our results suggest that the IR criteria according to Barja allows to identify cases with higher metabolic risk.

ABSTRACT

ABSTRACT BACKGROUND: Hepatitis C virus (HCV) infection is a serious public health problem, that affects approximately 170 million people worldwide. Chronic HCV infection is associated with hepatic insulin resistance and an increased risk of diabetes HCV-infected patients has been well documented. OBJECTIVE: To assess the homeostasis model assessment of insulin resistance (HOMA-IR) index in patients treated with direct acting antiviral (DAAs) medication in the sustained virological response (SVR), categorized by the presence or absence of cirrhosis. METHODS: A prospective study was conducted. Data were collected at the beginning of treatment (t-base) and in the twelfth week after the completion of treatment (t-SVR12). The inclusion criteria were presence of: HCV infection (RNA-HCV positive), age ≥18 years, completion of DAAs' therapy, and presence of diabetes with use of oral hypoglycemic agents. All samples were collected during the study period. The exclusion criteria were: presence of HBV/HIV co-infection, hepatocellular carcinoma at baseline, diabetic patients taking insulin and transplanted patients (liver/kidney). Fibrosis was assessed by hepatic elastography or biopsy (METAVIR). Cirrhosis was determined by clinical results or imaging. HOMA-IR was calculated as fasting insulin (μU/mL) × fasting glucose (mmol/L)/22.5) The patients were divided into two groups: the general study population (all patients, including the diabetic patients) and the special population (patients with normal values of HOMA-IR, which is >2.5, and without diabetes). The delta HOMA-IR value was calculated as: HOMA-IR at t-base - HOMA-IR at t-SVR12. For the descriptive statistical analysis, the paired t-test and generalized linear model assuming the log binding function were performed. A P value of < 0.05 was considered significant. RESULTS: We included 150 patients, and 75 were cirrhotic. The mean age was 55.3±9.97 and body mass index was 27.4±5.18. Twenty-two (14.67%) were diabetic patients using oral hypoglycemic agents, and 17 (11%) were cirrhotic. In the general study population, the mean glucose and HOMA-IR values increased at t-SVR12, but insulin decreased. Delta HOMA-IR was negative at t-SVR12, but there was no significant difference. Excluding diabetic patients and those with normal HOMA-IR values (<2.5), mean glucose, insulin and HOMA-IR decreased at t-SVR12. Delta HOMA-IR decreased significantly at t-SVR12 (P: 0.02). CONCLUSION: In the general population, glucose and HOMA-IR values increased at t-SVR12, but insulin decreased. In the special population, glucose, insulin, HOMA-IR and Delta HOMA-IR decreased at t-SVR12.


RESUMO CONTEXTO: A infecção pelo vírus da hepatite C (VHC) é um grave problema de saúde pública, que afeta aproximadamente 170 milhões de pessoas no mundo. A infecção crônica pelo VHC está associada à resistência à insulina hepática e a um risco aumentado de diabetes. Os doentes infetados pelo VHC foram bem documentados. OBJETIVO: Avaliar o modelo de avaliação da homeostase do índice de resistência à insulina (HOMA-IR) em pacientes tratados com medicação antiviral de ação direta na resposta virológica sustentada (RVS), categorizada pela presença ou ausência de cirrose. MÉTODOS: Foi realizado um estudo prospectivo. Os dados foram coletados no início do tratamento (t-base) e na décima segunda semana após o término do tratamento (t-RVS12). Os critérios de inclusão foram presença de: infecção pelo VHC (RNA-VHC positivo), idade ≥18 anos, conclusão da terapia de antivirais de ação direta e presença de diabetes com uso de hipoglicemiantes orais. Todas as amostras foram coletadas durante o período do estudo. Os critérios de exclusão foram: presença de coinfecção VHB/HIV, carcinoma hepatocelular no início do estudo, pacientes diabéticos em uso de insulina e pacientes transplantados (fígado/rim). A fibrose foi avaliada por elastografia hepática ou biópsia (METAVIR). A cirrose foi determinada por resultados clínicos ou exames de imagem. O HOMA-IR foi calculado como insulinemia de jejum (μU/mL) x glicemia de jejum (mmol/L) /22,5). Os pacientes foram divididos em dois grupos: a população geral do estudo (todos os pacientes, incluindo os diabéticos) e a população especial (pacientes com valores normais de HOMA-IR, que é <2,5 e sem diabetes). O valor do delta HOMA-IR foi calculado como: HOMA-IR no t-base - HOMA-IR no t-RVS12. Para a análise estatística descritiva, foram utilizados o teste t pareado e o modelo linear generalizado, assumindo a função de ligação logarítmica. Um valor de P<0,05 foi considerado significativo. RESULTADOS: Foram incluídos 150 pacientes e 75 eram cirróticos. A idade média foi de 55,3±9,97 e o índice de massa corpórea foi de 27,4±5,18. Vinte e dois (14,67%) eram pacientes diabéticos em uso de hipoglicemiantes orais e 17 (11%) eram cirróticos. Na população geral do estudo, os valores médios de glicose e HOMA-IR aumentaram na t-SVR12, mas a insulina diminuiu. O delta HOMA-IR foi negativo em t-SVR12, mas não houve diferença significativa. Excluindo pacientes diabéticos e aqueles com valores normais de HOMA-IR (<2,5), a média de glicose, insulina e HOMA-IR diminuiu no t-RVS12. O delta HOMA-IR diminuiu significativamente em t-RVS12 (P: 0,02). CONCLUSÃO: Na população geral, os valores de glicose e HOMA-IR aumentaram no t-RVS12, mas a insulina diminuiu. Na população especial, glicose, insulina, HOMA-IR e delta HOMA-IR diminuíram no t-RVS12.
