Nationwide multicenter study on the prevalence of overweight and obesity in type 2 diabetes mellitus in the Brazilian population

AIM: To evaluate the prevalence of overweight and obesity in type 2 diabetic (DM2) outpatients from different regions of Brazil. PATIENTS AND METHODS: We studied 2,519 randomly selected patients, from 11 hospitals, 2 endocrine and one general public care clinics from 10 cities. Overweight was defined as body-mass index (BMI) > 25 and obesity as BMI > 30 kg/m². Glycemic control (GC) was evaluated by GC index (GCI= patient's HbA1 or HbA1c/upper limit of normal for the method x 100). RESULTS: 39% of the population studied was male, the mean age was 58.8 ± 11.6 y, the duration from clinical diagnosis of DM2 was 9.0 ± 7.3y, and BMI was 28.3 ± 5.2 kg/m². No measurements of BMI were recorded from 265 patients (10.5%). Patients from the Northeast presented lower BMI as compared with those from the Midwest, Southeast and South areas, respectively (26.4 ± 4.7 vs. 27.9 ± 4.8 vs. 29.2 ± 5.1 vs. 29.4 ± 5.4 kg/m²; p 25 e obesidade um IMC > 30 kg/m². O controle glicêmico (CG) foi avaliado pelo índice de CG [ICG= HbA1 e ou HbA1c do paciente/limite superior de normalidade do método x 100]. RESULTADOS: Os pacientes tinham idade de 58,8 ± 11,6 anos, tempo de diagnóstico clínico de DM de 9,0 ± 7,3 anos, IMC de 28,3 ± 5,2 kg/m², e 39% eram do sexo masculino. Do total da amostra, 265 pacientes (10,5%) não apresentavam avaliação do IMC. Os pacientes da região Nordeste apresentaram menor IMC em comparação com os das regiões Centro-Oeste, Sudeste e Sul, respectivamente (26,4 ± 4,7 vs. 27,9 ± 4,8 vs. 29,2 ± 5,1 vs. 29,4 ± 5,4 kg/m²; p< 0,001). Houve maior prevalência de obesidade na região Sudeste e Sul em comparação à região Nordeste (p< 0,001) e nos pacientes do sexo feminino, respectivamente (69 vs. 31%; p< 0,001). Os pacientes com peso normal apresentaram menor ICG. Aqueles em tratamento com associação de duas ou mais drogas orais e associação de insulina + droga oral apresentaram maior IMC do que aqueles em tratamento com dieta, hipoglicemiante oral e insulina; p< 0,001. O IMC não diferiu entre os pacientes assistidos ou não por especialistas. CONCLUSÕES: Da população estudada, 75% não estava na faixa de peso ideal, sendo que um terço tinha obesidade. Nossos dados indicam que o sobrepeso e a obesidade já atingem um percentual de pacientes com DM2 no Brasil semelhante ao relatado em estudos europeus, mas ainda menor do que o observado nos EUA. A prevalência de obesidade nos pacientes diabéticos foi três vezes maior do que a observada na população brasileira em geral de acordo com os dados do IBGE.UERJUSPUNIFESP-EPMUNICAMPUNIFEUniversidade Federal do MaranhãoCEDEBVA Serviço de Endocrinologia e DiabetesHospital Agamenon Magalhães Serviços de EndocrinologiaSanta Casa Serviços de EndocrinologiaIAPSEB Serviços de EndocrinologiaHospital Geral Serviços de EndocrinologiaPAM Jaguaribe Serviços de EndocrinologiaSanta Casa Serviço de DiabetesSecretaria Municipal de SaúdeUNIFESP, EPMSciEL

Is MR Spectroscopy Really the Best MR-Based Method for the Evaluation of Fatty Liver in Diabetic Patients in Clinical Practice?

Objective: To investigate if magnetic resonance spectroscopy (MRS) is the best Magnetic Resonance (MR)-based method when compared to gradient-echo magnetic resonance imaging (MRI) for the detection and quantification of liver steatosis in diabetic patients in the clinical practice using liver biopsy as the reference standard, and to assess the influence of steatohepatitis and fibrosis on liver fat quantification.Methods: Institutional approval and patient consent were obtained for this prospective study. Seventy-three patients with type 2 diabetes (60 women and 13 men; mean age, 5469 years) underwent MRI and MRS at 3.0 T. the liver fat fraction was calculated from triple-and multi-echo gradient-echo sequences, and MRS data. Liver specimens were obtained in all patients. the accuracy for liver fat detection was estimated by receiver operator characteristic (ROC) analysis, and the correlation between fat quantification by imaging and histolopathology was analyzed by Spearman's correlation coefficients.Results: the prevalence of hepatic steatosis was 92%. All gradient-echo MRI and MRS findings strongly correlated with biopsy findings (triple-echo, rho = 0.819; multi-echo, rho = 0.773; MRS, rho = 0.767). Areas under the ROC curves to detect mild, moderate, and severe steatosis were: triple-echo sequences, 0.961, 0.975, and 0.962; multi-echo sequences, 0.878, 0.979, and 0.961; and MRS, 0.981, 0.980, and 0.954. the thresholds for mild, moderate, and severe steatosis were: triple-echo sequences, 4.09, 9.34, and 12.34, multi-echo sequences, 7.53, 11.75, and 15.08, and MRS, 1.71, 11.69, and 14.91. Quantification was not significantly influenced by steatohepatitis or fibrosis.Conclusions: Liver fat quantification by MR methods strongly correlates with histopathology. Due to the wide availability and easier post-processing, gradient-echo sequences may represent the best imaging method for the detection and quantification of liver fat fraction in diabetic patients in the clinical practice.D'Or Institute for Research and EducationFundação de Amparo à Pesquisa do Estado do Rio de Janeiro (FAPERJ)DOr Inst Res & Educ, Rio de Janeiro, BrazilUniv Fed Rio de Janeiro, Rio de Janeiro, BrazilUniv Estado Rio de Janeiro, Rio de Janeiro, BrazilUniv São Paulo, Inst Phys Sao Carlos, Sao Carlos, SP, BrazilUniversidade Federal de São Paulo, São Paulo, BrazilUniv Paris Diderot Sorbonne, Paris, FranceUniversidade Federal de São Paulo, São Paulo, BrazilWeb of Scienc

Lower insulin-dose adjusted A1c (IDAA1c) is associated with less complications in Individuals with Type 1 Diabetes treated with hematopoetic stem-cell transplantation and conventional therapy

Objective: To evaluate the association between insulin-dose adjusted A1C (IDAA1c) and microvascular complications (MC) and hypoglycemia in a representative Brazilian population of Type 1 diabetes mellitus (T1DM) patients. Research Design and Methods: This was a cross-sectional study based on a previous study, “Microvascular Complications in Type 1 Diabetes: a comparative analysis of patients treated with autologous nonmyeloablative hematopoietic stem-cell transplantation (AHST) and conventional medical therapy (CT)”. The 168 patients in that study (144 from CT plus 24 from AHST) were re-subdivided into two groups, according to their IDAA1c values (30 patients had IDAA1c ≤ 9; 138 had IDAA1c > 9). Then, the prevalence of MC (diabetic renal disease, neuropathy, and retinopathy), hypoglycemia (blood glucose <60 mg/dL), and severe hypoglycemic (episode of hypoglycemia that required the assistance of another person to treat) events were compared between the groups. The groups were well-matched on these factors: duration of disease, sex, and age at the time of diagnosis of T1DM. Results: After an average of 8 years after diagnosis, only 6.6% (2/30) of the patients from IDAA1c ≤ 9 group developed any MC, whereas 21.0% (29/138) from the IDAA1c > 9 group had at least one complication (p = 0.044). Regarding hypoglycemic events, the proportion of individuals who reported at least 1 episode of hypoglycemia in the last month was 43.3 and 64.7% from the IDAA1c ≤ 9 and IDAA1c > 9 groups, respectively (p = 0.030). Regarding severe hypoglycemia, the proportion of patients presenting at least one episode in the last month and the rate of episode/patient/month were similar between groups (6.7 vs. 13.2%; p = 0.535; and 0.1/patient/month vs. 0.25/patient/month; p = 0.321). Conclusion: In a representative Brazilian population of T1DM patients, those with IDAA1c ≤ 9 presented a lower frequency of MC, as well as fewer episodes of hypoglycemia, in the month prior to the analysis.publishedVersio

Health-related quality of life in patients with type 1 diabetes mellitus in the different geographical regions of Brazil : data from the Brazilian Type 1 Diabetes Study Group

Background: In type 1 diabetes mellitus (T1DM) management, enhancing health-related quality of life (HRQoL) is as important as good metabolic control and prevention of secondary complications. This study aims to evaluate possible regional differences in HRQoL, demographic features and clinical characteristics of patients with T1DM in Brazil, a country of continental proportions, as well as investigate which variables could influence the HRQoL of these individuals and contribute to these regional disparities. Methods: This was a retrospective, cross-sectional, multicenter study performed by the Brazilian Type 1 Diabetes Study Group (BrazDiab1SG), by analyzing EuroQol scores from 3005 participants with T1DM, in 28 public clinics, among all geographical regions of Brazil. Data on demography, economic status, chronic complications, glycemic control and lipid profile were also collected. Results: We have found that the North-Northeast region presents a higher index in the assessment of the overall health status (EQ-VAS) compared to the Southeast (74.6 ± 30 and 70.4 ± 19, respectively; p < 0.05). In addition, North- Northeast presented a lower frequency of self-reported anxiety-depression compared to all regions of the country (North-Northeast: 1.53 ± 0.6; Southeast: 1.65 ± 0.7; South: 1.72 ± 0.7; Midwest: 1.67 ± 0.7; p < 0.05). These findings could not be entirely explained by the HbA1c levels or the other variables examined. Conclusions: Our study points to the existence of additional factors not yet evaluated that could be determinant in the HRQoL of people with T1DM and contribute to these regional disparities

Desafios e Avanços no Manejo da Hemorragia Pós-Parto: Estratégias Emergentes e Melhores Práticas

This article presents a literature review on the management of postpartum hemorrhage (PPH), focusing on emerging strategies and best practices. PPH is a significant obstetric complication that continues to pose a challenge for healthcare professionals. The review encompasses guidelines and recommendations from organizations such as the American College of Obstetricians and Gynecologists (ACOG) and the World Health Organization (WHO), as well as highlighting studies on arterial embolization and other innovative interventions. The results emphasize the importance of a multidisciplinary approach and early identification of PPH to prevent serious complications. It is concluded that arterial embolization emerges as a valuable option in the management of refractory PPH, but its use should be carefully considered in conjunction with other therapeutic and preventive approaches.Este artigo apresenta uma revisão da literatura sobre o manejo da hemorragia pós-parto (HPP), com foco em estratégias emergentes e melhores práticas. A HPP é uma complicação obstétrica significativa que continua a representar um desafio para os profissionais de saúde. A revisão abrange diretrizes e recomendações de organizações como o Colégio Americano de Obstetras e Ginecologistas (ACOG) e a Organização Mundial da Saúde (OMS), além de destacar estudos sobre embolização arterial e outras intervenções inovadoras. Os resultados destacam a importância da abordagem multidisciplinar e da identificação precoce da HPP para prevenir complicações graves. Conclui-se que a embolização arterial surge como uma opção valiosa no manejo da HPP refratária, mas que seu uso deve ser cuidadosamente considerado em conjunto com outras abordagens terapêuticas e preventivas

Determinants of intensive insulin therapeutic regimens in patients with type 1 diabetes: data from a nationwide multicenter survey in Brazil

Background: To evaluate the determinants of intensive insulin regimens (ITs) in patients with type 1 diabetes (T1D).Methods: This multicenter study was conducted between December 2008 and December 2010 in 28 public clinics in 20 Brazilian cities. Data were obtained from 3,591 patients (56.0% female, 57.1% Caucasian). Insulin regimens were classified as follows: group 1, conventional therapy (CT) (intermediate human insulin, one to two injections daily); group 2 (three or more insulin injections of intermediate plus regular human insulin); group 3 (three or more insulin injections of intermediate human insulin plus short-acting insulin analogues); group 4, basal-bolus (one or two insulin injections of long-acting plus short-acting insulin analogues or regular insulin); and group 5, basal-bolus with continuous subcutaneous insulin infusion (CSII). Groups 2 to 5 were considered IT groups.Results: We obtained complete data from 2,961 patients. Combined intermediate plus regular human insulin was the most used therapeutic regimen. CSII was used by 37 (1.2%) patients and IT by 2,669 (90.2%) patients. More patients on IT performed self-monitoring of blood glucose and were treated at the tertiary care level compared to CT patients (p < 0.001). the majority of patients from all groups had HbA1c levels above the target. Overweight or obesity was not associated with insulin regimen. Logistic regression analysis showed that economic status, age, ethnicity, and level of care were associated with IT (p < 0.001).Conclusions: Given the prevalence of intensive treatment for T1D in Brazil, more effective therapeutic strategies are needed for long term-health benefits.Farmanguinhos/Fundacao Oswaldo Cruz/National Health MinistryBrazilian Diabetes SocietyFundacao do Amparo a Pesquisa do Estado do Rio de JaneiroConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Univ Estado Rio de Janeiro, Unit Diabet, BR-20551030 Rio de Janeiro, BrazilBaurus Diabet Assoc, São Paulo, BrazilFed Univ São Paulo State, Diabet Unit, São Paulo, BrazilFed Univ Hosp Porto Alegre, Porto Alegre, BrazilUniv Hosp São Paulo, Diabet Unit, São Paulo, BrazilUniv Fed Rio de Janeiro, Rio de Janeiro, BrazilUniv Fed Ceara, Fortaleza, Ceara, BrazilSanta Casa Misericordia, Belo Horizonte, MG, BrazilSanta Casa Misericordia São Paulo, São Paulo, BrazilUniv Fed Amazonas, Manaus, Amazonas, BrazilHosp Geral de Bonsucesso, Rio de Janeiro, BrazilHosp Univ Clementino Fraga Filho IPPMG, Rio de Janeiro, BrazilUniv Hosp São Paulo, São Paulo, BrazilFac Ciencias Med Santa Casa São Paulo, São Paulo, BrazilUniv São Paulo, Inst Crianca, Hosp Clin, São Paulo, BrazilUniv São Paulo, Fac Med Ribeirao Preto, Hosp Clin, Ribeirao Preto, BrazilAmbulatorio Fac Estadual Med Sao Jose Rio Preto, Ribeirao Preto, BrazilEscola Paulista Med, Ctr Diabet, Ribeirao Preto, BrazilClin Endocrinol Santa Casa Belo Horizonte, Belo Horizonte, MG, BrazilUniv Estadual Londrina, Londrina, BrazilUniv Fed Parana, Hosp Clin, Porto Alegre, RS, BrazilInst Crianca Com Diabet Rio Grande Sul, Rio Grande Do Sul, RS, BrazilGrp Hosp Conceicao, Inst Crianca Com Diabet, Porto Alegre, RS, BrazilHosp Univ Santa Catarina, Florianopolis, SC, BrazilInst Diabet Endocrinol Joinville, Joinville, BrazilHosp Reg Taguatinga, Brasilia, DF, BrazilHosp Geral Goiania, Goiania, Go, BrazilCtr Diabet & Endocrinol Estado Bahia, Goiania, Go, BrazilUniv Fed Maranhao, Sao Luis, BrazilCtr Integrado Diabet & Hipertensao Ceara, Fortaleza, Ceara, BrazilUniv Fed Sergipe, Aracaju, BrazilHosp Univ Alcides Carneiro, Campina Grande, BrazilHosp Univ Joao de Barros Barreto, Belem, Para, BrazilFed Univ São Paulo State, Diabet Unit, São Paulo, BrazilUniv Hosp São Paulo, Diabet Unit, São Paulo, BrazilUniv Hosp São Paulo, São Paulo, BrazilEscola Paulista Med, Ctr Diabet, Ribeirao Preto, BrazilWeb of Scienc
