RESUMO

Dietary restriction (DR) reduces adiposity and improves metabolism in patients with one or more symptoms of metabolic syndrome. Nonetheless, it remains elusive whether the benefits of DR in humans are mediated by calorie or nutrient restriction. This study was conducted to determine whether isocaloric dietary protein restriction is sufficient to confer the beneficial effects of dietary restriction in patients with metabolic syndrome. We performed a prospective, randomized controlled dietary intervention under constant nutritional and medical supervision. Twenty-one individuals diagnosed with metabolic syndrome were randomly assigned for caloric restriction (CR; n = 11, diet of 5941 ± 686 KJ per day) or isocaloric dietary protein restriction (PR; n = 10, diet of 8409 ± 2360 KJ per day) and followed for 27 days. Like CR, PR promoted weight loss due to a reduction in adiposity, which was associated with reductions in blood glucose, lipid levels, and blood pressure. More strikingly, both CR and PR improved insulin sensitivity by 62.3% and 93.2%, respectively, after treatment. Fecal microbiome diversity was not affected by the interventions. Adipose tissue bulk RNA-Seq data revealed minor changes elicited by the interventions. After PR, terms related to leukocyte proliferation were enriched among the upregulated genes. Protein restriction is sufficient to confer almost the same clinical outcomes as calorie restriction without the need for a reduction in calorie intake. The isocaloric characteristic of the PR intervention makes this approach a more attractive and less drastic dietary strategy in clinical settings and has more significant potential to be used as adjuvant therapy for people with metabolic syndrome.

RESUMO

OBJECTIVE: Insulin sensitivity evaluation by hyperinsulinemic-euglycemic clamp in nonclassical congenital adrenal hyperplasia (NC-CAH) due to 21-hydroxilase deficiency. DESIGN AND SETTING: Cross-sectional study at university hospital outpatient clinics. PATIENTS AND METHODS: NC-CAH patients (25 females, 6 males; 24 ± 10 years) subdivided into C/NC (compound heterozygous for 1 classical and 1 nonclassical allele) and NC/NC (2 nonclassical alleles) genotypes were compared to controls. RESULTS: At diagnosis, C/NC patients presented higher basal and adrenocorticotropin-stimulated 17-hydroxyprogesterone and androstenedione levels than NC/NC genotype. Patients and controls presented similar weight, body mass index, abdominal circumference, and total fat body mass. NC-CAH patients showed higher waist-to-hip ratio, lower adiponectin and lower high-density lipoprotein cholesterol levels with no changes in fasting plasma glucose, glycated hemoglobin, homeostatic model assessment for insulin resistance, leptin, interleukin 6, tumor necrosis factor alpha, C-reactive protein, and carotid-intima-media thickness. All patients had used glucocorticoid (mean time of 73 months). Among the 22 patients with successful clamp, 13 were still receiving glucocorticoid-3 patients using cortisone acetate, 9 dexamethasone, and 1 prednisone (hydrocortisone equivalent dose of 5.5mg/m²/day), while 9 patients were off glucocorticoid but had previously used (hydrocortisone equivalent dose of 5.9mg/m2/day). The NC-CAH patients presented lower Mffm than controls (31 ± 20 vs 55 ± 23µmol/min-1/kg-1, P = 0.002). The Mffm values were inversely correlated with the duration of glucocorticoid treatment (r = -0.44, P = 0.04). There was association of insulin resistance and glucocorticoid type but not with androgen levels. CONCLUSION: Using the gold standard method, the hyperinsulinemic-euglycemic clamp, insulin resistance was present in NC-CAH patients and related to prolonged use and long-acting glucocorticoid treatment. Glucocorticoid replacement and cardiometabolic risks should be monitored regularly in NC-CAH.

RESUMO

Night work has become necessary in our modern society. However, sleep deprivation induces a circadian misalignment that effectively contributes to the development of diseases associated with metabolic syndrome, such as obesity and diabetes. Here, we evaluated the pattern of circadian clock genes and endoplasmic reticulum stress (ERS) genes in addition to metabolic and anthropometric measures in subjects that work during a nocturnal period compared with day workers. We study 20 night workers (NW) and 20 day workers (DW) submitted to a work schedule of 12 h of work for 36 h of rest for at least 5 years in a hospital. The present report shows that NW have increased fasting blood glucose, glycated hemoglobin (HbA1c), triglycerides, and low-density lipoprotein (LDL)-cholesterol levels, and lower high-density lipoprotein (HDL)-cholesterol levels compared to DW. In addition, we observed that waist circumference (WC), waist-hip ratio (WHR), and systemic blood pressure are also increased in NW. Interestingly, gene expression analysis showed changes in CLOCK gene expression in peripheral blood mononuclear cells (PBMC) samples of NW compared to the DW, evidencing a peripheral circadian misalignment. This metabolic adaptation was accompanied by the up-regulation of many genes of ERS in NW. These findings support the hypothesis that night shift work results in disturbed glycemic and lipid control and affects the circadian cycle through the deregulation of peripheral CLOCK genes, which is possibly due to the activation of ERS. Thus, night work induces important metabolic changes that increase the risk of developing metabolic syndrome.

RESUMO

BACKGROUND: Bariatric surgery, especially Roux-en-Y gastric bypass (RYGB), is the most effective and durable treatment option for severe obesity. The mechanisms involving adipose tissue may be important to explain the effects of surgery. METHODS: We aimed to identify the genetic signatures of adipose tissue in patients undergoing RYGB. We evaluated 13 obese, non-diabetic patients (mean age 37 years, 100% women, Body mass index (BMI) 42.2 kg/m2) one day before surgery, 3 and 6 months (M) after RYGB. RESULTS: Analysis of gene expression in adipose tissue collected at surgery compared with samples collected at 3 M and 6 M Post-RYGB showed that interleukins [Interleukin 6, Tumor necrosis factor-α (TNF-α), and Monocyte chemoattractant protein-1(MCP1)] and endoplasmic reticulum stress (ERS) genes [Eukaryotic translation initiation factor 2 alpha kinase 3 (EIF2AK3) and Calreticulin (CALR)] decreased during the follow-up (P ≤ 0.01 for all). Otherwise, genes involved in energy homeostasis [Adiponectin and AMP-activated protein kinase (AMPK)], cellular response to oxidative stress [Sirtuin 1, Sirtuin 3, and Nuclear factor erythroid 2-related factor 2 (NRF2)], mitochondrial biogenesis [Peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC1α)] and amino acids metabolism [General control nonderepressible 2 (GCN2)] increased from baseline to all other time points evaluated (P ≤ 0.01 for all). Also, expression of Peroxisome proliferator-activated receptor gamma (PPARϒ) (adipogenesis regulation) was significantly decreased after RYGB (P < 0.05). Additionally, we observed that PGC1α, SIRT1 and AMPK strongly correlated to BMI at 3 M (P ≤ 0.01 for all), as well as ADIPOQ and SIRT1 to BMI at 6 M (P ≤ 0.01 for all). CONCLUSIONS: Our findings demonstrate that weight loss is associated with amelioration of inflammation and ERS and increased protection against oxidative stress in adipose tissue. These observations are strongly correlated with a decrease in BMI and essential genes that control cellular energy homeostasis, suggesting an adaptive process on a gene expression level during the caloric restriction and weight loss period after RYGB.

RESUMO

Aldosterone excess aggravates endothelial dysfunction in diabetes and hypertension by promoting the increased generation of reactive oxygen species, inflammation, and insulin resistance. Aldosterone activates the molecular platform inflammasome in immune system cells and contributes to vascular dysfunction induced by the mineralocorticoid hormone. It is unclear as to whether the NLRP3 inflammasome associated with the mineralocorticoid receptor contributes to vascular dysfunction in diabetic conditions. Here, we tested the hypothesis that an excess of aldosterone induces vascular dysfunction in type 2 diabetes, via the activation of mineralocorticoid receptors (MR) and assembly of the NLRP3 inflammasome. Mesenteric resistance arteries from control (db/m) and diabetic (db/db) mice treated with vehicle, spironolactone (MR antagonist) or an NLRP3 selective inhibitor (MCC950) were used to determine whether NLRP3 contributes to diabetes-associated vascular dysfunction. Db/db mice exhibited increased vascular expression/activation of caspase-1 and IL-1ß, increased plasma IL-1ß levels, active caspase-1 in peritoneal macrophages, and reduced acetylcholine (ACh) vasodilation, compared to db/m mice. Treatment of db/db mice with spironolactone and MCC950 decreased plasma IL-1ß and partly restored ACh vasodilation. Spironolactone also reduced active caspase-1-positive macrophages in db/db mice, events that contribute to diabetes-associated vascular changes. These data clearly indicate that MR and NLRP3 activation contribute to diabetes-associated vascular dysfunction and pro-inflammatory phenotype.

RESUMO

Detrimental drug-drug interactions (DDIs) in Diabetic patients could be from the simultaneous use of multiple drugs, polypharmacy. Brazilian public health studies evaluating the practical knowledge about drug interactions are scarce. This study's objective is to identify drug interactions and prevalence of detrimental DDIs in diabetic patients attending Brazilian basic health system clinics. METHODS: Patients using insulin between the age of 18-90 years were selected to complete the MedTake questionnaire, to evaluate the indication, dosage, regimen and drug interaction. The MedTake test was employed. For each medicine, the test was scored as the percentage of correct actions and compared with printed instructions one single researcher downloaded all the data was from the municipality's computerized system. RESULTS: The median age of recruits was 60.2 ±â€¯14.3 and MedTake test scores were low 60.3 ±â€¯20. One hundred patients missed the correct dose question, 40 missed why they were prescribed the drug, indication and 65 missed the therapeutic regimen. These diabetes patients did not know the DDIs between insulin combined with other medicines. Drugs that had more interaction with insulin were: acetylsalicylic acid (40%), enalapril (18%), losartan (32%) and hydrochlorothiazide (23%). CONCLUSIONS: Diabetes patients without practical knowledge about insulin interacting with other pharmaceutical drugs that can produce DDIs with other medicines illustrates a need to develop education programs for diabetics.

RESUMO

The rising prevalence of T2DM poses a serious threat to human health and the viability of many health care systems around the world. Non-adherence to therapeutic in the T2DM is high, and Brazilian studies of public heath for to identify new variables are scares. The present study explored cardiovascular consequences associated with compliance and non-adherence among T2DM in Brazilian patients seeking medical care in Brazilian basic health unit clinics. METHODS: This is a cross-sectional study carried out in a city the interior of Sao Paulo state, with patients with T2DM, being municipal PHS users. Data were collected from the computerized system of the municipality for a one single researcher and patient records, and analyzed using the IBM SPSS v.18 statistical package. The response variables was categorized in adherent MGT (>80) and non-adherent MGT (≤80). RESULTS: The mean age of patients was 63.6 ±â€¯9.5 with predominance for the sex male 66.4% and 42% of patients with T2DM do not adherence to treatment. We found an associated odds ratio (OR) = 2.3 (1.1-5.1) between heart failure and non-adherence in patients with T2DM. CONCLUSION: Heart failure is a factor associated with non-adherence to treatment in patients with T2DM and in the practice clinical, the screening for heart failure and interventions may improve adherence to pharmacotherapy.

RESUMO

Familial partial lipodystrophy type 2 (FPLD2) is characterized by insulin resistance, adipose atrophy of the extremities and central obesity. Due to the resemblance with Cushing's syndrome, we hypothesized a putative role of glucocorticoid in the pathogenesis of metabolic abnormalities in FPLD2. OBJECTIVE: To evaluate the phenotypic heterogeneity and glucocorticoid sensitivity in FPLD2 patients exhibiting the p.R482W or p.R644C LMNA mutations. DESIGN, PATIENTS AND MEASUREMENTS: Prospective study with FPLD2 patients (n = 24) and controls (n = 24), who underwent anthropometric, body composition, metabolic profile and adipokines/cytokine plasma measurements. Plasma and salivary cortisol were measured in basal conditions and after 0.25, 0.5 and 1.0 mg of dexamethasone (DEX) given at 23:00 hours. Glucocorticoid receptor (GR) and 11ßHSD isoforms expression were assessed by qPCR. RESULTS: Familial partial lipodystrophy type 2 individuals presented increased waist and neck circumferences, decreased hip circumference, peripheral skinfold thickness and fat mass. Patients presented increased HOMA-IR, triglycerides, TNF-α, IL-1ß, IL-6 and IL-10, and decreased adiponectin and leptin plasma levels. FPLD2 patients showed decreased ability to suppress the HPA axis compared with controls after 0.5 mg DEX. The phenotype was more pronounced in patients harbouring the p.R482W LMNA mutation. GRß overexpression in PBMC was observed in female patients compared with female controls. CONCLUSIONS: Familial partial lipodystrophy type 2 patients exhibited anthropometric, clinical and biochemical phenotypic heterogeneity related to LMNA mutation sites and to gender. LMNA mutations affecting both lamin A and lamin C lead to more severe phenotype. FPLD2 patients also showed blunted HPA axis response to DEX, probably due to the association of increased levels of proinflammatory cytokines with GRß overexpression leading to a more severe phenotype in female.

RESUMO

The delayed diagnosis and the inadequate treatment of diabetes increase the risk of chronic complications. The study of regulatory molecules such as miRNAs can provide expression profiles of diabetes and diabetes complications. We evaluated the mononuclear cell miRNA profiles of 63 Type 1 and Type 2 diabetes patients presenting or not microvascular complications, and 40 healthy controls, using massive parallel sequencing. Gene targets, enriched pathways, dendograms and miRNA-mRNA networks were performed for the differentially expressed miRNAs. Six more relevant miRNAs were validated by RT-qPCR and data mining analysis. MiRNAs associated with specific complications included: i) neuropathy (miR-873-5p, miR-125a-5p, miR-145-3p and miR-99b-5p); ii) nephropathy (miR-1249-3p, miR-193a-5p, miR-409-5p, miR-1271-5p, miR-501-3p, miR-148b-3p and miR-9-5p); and iii) retinopathy (miR-143-3p, miR-1271-5p, miR-409-5p and miR-199a-5p). These miRNAs mainly targeted gene families and specific genes associated with advanced glycation end products and their receptors. Sets of miRNAs were also defined as potential targets for diabetes/diabetes complication pathogenesis.

RESUMO

OBJECTIVES: Dietary omega-3 fatty acids have been efficacious in decreasing serum cholesterol levels and reducing the risk of cardiovascular disease. However, the metabolic and molecular changes induced by the omega-3 fatty acid α-linolenic acid (ALA), which is found in linseed oil, are not fully understood. In this study, we showed a correlation between ALA and insulin resistance, inflammation and endoplasmic reticulum stress (ERS). METHODS: We studied 40 male mice (C57/BL6) divided into 4 groups: a control (C) group, a control + omega-3/ALA (CA) group, a high-fat diet (HFD) (H) group and a high-fat diet + omega-3/ALA (HA) group. For 8 weeks, the animals in the H and HA groups were fed a high-fat (60%) diet, while the animals in the C and CA groups received regular chow. The diets of the CA and HA groups were supplemented with 10% lyophilized ALA. RESULTS: ALA supplementation improved glucose tolerance and reduced insulin resistance, as measured by intraperitoneal glucose tolerance tests and the homeostasis model assessment for insulin resistance, respectively. In addition, ALA reduced hepatic steatosis and modified the standard fat concentration in the liver of animals fed an HFD. Dietary ALA supplementation reduced the serum levels of interleukin 6 (IL-6), interleukin 1 beta (IL-1ß) and monocyte chemoattractant protein-1 (MCP-1), increased the expression of important chaperones such as binding immunoglobulin protein (BIP) and heat shock protein 70 (HSP70) and reduced the expression of C/EBP-homologous protein (CHOP) and X-box binding protein 1 (XBP1) in hepatic tissues, suggesting an ERS adaptation in response to ALA supplementation. CONCLUSIONS: Dietary ALA supplementation is effective in preventing hepatic steatosis; is associated with a reduction in insulin resistance, inflammation and ERS; and represents an alternative for improving liver function and obtaining metabolic benefits.

RESUMO

INTRODUCTION: The HIV lipodystrophy syndrome is characterized by changes in metabolism, and body composition that increase cardiovascular risk of people living with HIV/AIDS (PLWHA) using highly active antiretroviral therapy (HAART). OBJECTIVE: To assess the prevalence of lipodystrophy and changes in lipid and glucose metabolism in PLWHA in use of HAART. METHODS: For the anthropometric evaluation we measured weight, height and abdominal circumference (AC). For the lipodystrophy evaluation we conducted physical examination (subjective) and the (objective) examination of absorptiometry with X-ray dual energy (DEXA) by fat mass ratio (FMR). We also conducted lipid profile tests and fasting glucose and used the criteria suggested by The National Cholesterol Education Program III for metabolic disorders classification. RESULTS: The final sample consisted of 262 patients with a mean age of 44.3 ± 10.2 years. Lipodystrophy, according to the physical examination, was present in 47.7% (95%CI 41.7 - 53.8) of patients, while the prevalence using FMR (DEXA) was 40.8% (95%CI 33.1 - 48.5). Most (53.0%; 95%CI 47.0 - 59.1) of the patients showed increased abdominal adiposity according to AC. The most prevalent metabolic alterations were reduced HDL (67.6%; 95%CI 61.9 - 73.2) and hypertriglyceridemia (55.7%; 95%CI 49.7 - 61.7). CONCLUSION: The high prevalence of lipodystrophy and changes in lipid and glucose metabolism show the importance of early intervention in this group of patients to prevent cardiovascular complications.


INTRODUÇÃO: A síndrome da lipodistrofia do HIV é caracterizada por alterações no metabolismo e na composição corporal, que aumentam o risco cardiovascular de pessoas vivendo com HIV/AIDS (PVHA) em uso da terapia antirretroviral de alta potência (TARV). OBJETIVO: Avaliar a prevalência de lipodistrofia e de alterações do metabolismo de lipídios e glicose em PVHA em uso da TARV. MÉTODOS: Para avaliação antropométrica foram aferidos peso, estatura e circunferência abdominal (CA). Para avaliação da lipodistrofia foi realizado o exame físico (subjetivo) e o exame (objetivo) de absortometria com raios X de dupla energia (DEXA) por meio da razão de massa gorda (RMG). Foram também realizados exames de lipidograma e glicemia de jejum e utilizados os critérios sugeridos pelo The National Cholesterol Education Program III para classificação de alterações metabólicas. RESULTADOS: A amostra final consistiu em 262 pacientes com idade média de 44,3 ± 10,2 anos. A lipodistrofia, de acordo com o exame físico, esteve presente em 47,7% (IC95% 41,7 - 53,8) dos pacientes, enquanto pela RMG (DEXA) sua prevalência foi de 40,8% (IC95% 33,1 - 48,5). A maioria (53,0%; IC95% 47,0 - 59,1) dos pacientes apresentou aumento de adiposidade abdominal segundo a CA. As alterações metabólicas mais presentes foram o HDL reduzido (67,6%; IC95% 61,9 - 73,2) e a hipertrigliceridemia (55,7%; IC95% 49,7 - 61,7). CONCLUSÕES: A alta prevalência de lipodistrofia e alterações do metabolismo de lipídios e glicose evidenciam a importância da intervenção precoce nesse grupo de pacientes para prevenir complicações cardiovasculares.

Objective: To assess the prevalence of lipodystrophy and changes in lipid and glucose metabolism in PLWHA in use of HAART. Methods: For the anthropometric evaluation we measured weight, height and abdominal circumference (AC). For the lipodystrophy evaluation we conducted physical examination (subjective) and the (objective) examination of absorptiometry with X-ray dual energy (DEXA) by fat mass ratio (FMR). We also conducted lipid profile tests and fasting glucose and used the criteria suggested by The National Cholesterol Education Program III for metabolic disorders classification. Results: The final sample consisted of 262 patients with a mean age of 44.3 ± 10.2 years. Lipodystrophy, according to the physical examination, was present in 47.7% (95%CI 41.7 - 53.8) of patients, while the prevalence using FMR (DEXA) was 40.8% (95%CI 33.1 - 48.5). Most (53.0%; 95%CI 47.0 - 59.1) of the patients showed increased abdominal adiposity according to AC. The most prevalent metabolic alterations were reduced HDL (67.6%; 95%CI 61.9 - 73.2) and hypertriglyceridemia (55.7%; 95%CI 49.7 - 61.7). Conclusion: The high prevalence of lipodystrophy and changes in lipid and glucose metabolism show the importance of early intervention in this group of patients to prevent cardiovascular complications.

RESUMO

AIM: This randomized controlled clinical trial aimed to evaluate the contribution of family social support to the clinical/metabolic control of people with type 2 diabetes mellitus. BACKGROUND: Diabetes mellitus is a chronic disease that requires continuous care in order for individuals to reach glycemic control, the primordial goal of treatment. Family social support is essential to the development of care skills and their maintenance. However, there are few studies that investigate the contribution of family social support to diabetes control. METHODS: The study was developed between June 2011 and May 2013, and included 164 people who were randomized using simple randomization. The intervention group differed from the control group in that it included a family caregiver, who was recognized by the patient as a source of social support. The educational interventions received by people with diabetes mellitus were used as the basis of the education provided through telephone calls to patients' family members and caregivers, and their purpose was to encourage dialogue between the patients and their relatives about the topics related to diabetes. RESULTS: Regarding the clinical impact, the results showed that there was a greater reduction in blood pressure and glycated hemoglobin in the intervention group than in the control group, showing a positive effect on the control of the disease. CONCLUSIONS: Families should be incorporated into the care of people with diabetes mellitus and especially in health care programs, in particular those that can promote different forms of social support to strengthen the bond between family members.

RESUMO

INTRODUCTION: Familial partial lipodystrophy (FPL) is a rare genetic disorder characterized by selective lack of subcutaneous fat, which is associated with insulin-resistant diabetes. The Dunnigan variety (FPLD2) is caused by several missense mutations in the lamin A/C (LMNA) gene, most of which are typically located in exon 8 at the codon position 482. OBJECTIVE: The aim of this study was to assess and compare the dietary intake, leisure-time physical activity (LTPA), and biochemical measurements (glucose, A1C, and plasma lipids) in women with FPLD2 and without (control group, CG) and to examine the associations between dietary intake and biochemical measurements (BM). METHODS: LTPA was measured with a questionnaire and metabolic equivalent (MET) hours per week (hours/week) were calculated. Dietary intake by the 3-day recall method and clinical laboratory parameters were collected. RESULTS: Characteristics of women with FPLD2: 35.8 ± 13.9 years, fat mass = 10 ± 2.3 kg and fat free mass = 41.4 ± 4.5 kg (p < 0.05). Women with FPLD2 showed a smaller intake of energy (kcal), lipids, and carbohydrates and a large intake of protein (p < 0.01) compared to CG. Comparing the 2 groups in terms of LTPA, 78% of women with FPLD2 performed insufficient physical activity. In addition, they had a higher levels of glucose, A1C, and triglycerides (TG) and lower levels of high-density lipoprotein (HDL). There was no correlation between dietary intake and biochemical measurements. CONCLUSIONS: Women with FPLD2 have a lower intake of energy (kcal), lipids, and carbohydrates and greater changes in biochemical measurements. Because this is a rare disease, future studies are needed with encouragement of the practice of physical activity and of healthy eating habits, preventing the onset of diseases.

RESUMO

Besides the well recognized association of HLA-DRB1 and DQB1 alleles with type 1 diabetes mellitus (T1D), linkage studies have identified a gene region close to the non-classical class I HLA-G gene as an independent susceptibility marker. HLA-G is constitutively expressed in the endocrine compartment of the human pancreas and may play a role in controlling autoimmune responses. We evaluated the genetic diversity of the 3' untranslated region (3'UTR) of HLA-G, which have been associated with HLA-G mRNA post-transcriptional regulation, in 120 Brazilian T1D patients and in 120 healthy controls. We found the +3001 T allele was observed only in T1D patients. Notably, the +3001 T allele was in linkage disequilibrium with polymorphic sites associated with low production of HLA-G mRNA or soluble HLA-G levels. Moreover, T1D patients showed a low frequency of the HLA-G 3'UTR-17 (14bpINS/+3001T/+3003T/+3010C/+3027C/+3035T/+3142G/+3187A/+3196C). The +3010 CC genotype and the UTR-3 haplotype (14bpDEL/+3001C/+3003T/+3010C/+3027C/+3035C/+3142G/+3187A/+3196C), associated with low and moderate soluble HLA-G expression, respectively, were underrepresented in patients. The decreased expression of HLA-G at the pancreas level should be detrimental in individuals genetically prone to produce less HLA-G.

RESUMO

BACKGROUND: Highly active antiretroviral therapy (HAART) can cause side effects in HIV patients, as the metabolic syndrome. Early identification of risk for development of cardiovascular diseases using available reliable and practical methods is fundamental. On this basis, the aim of this study was to compare the effectiveness of anthropometric indicators to identify metabolic syndrome in HIV patients on HAART. METHODS: It is a cross-sectional study. A number of 280 stable HIV patients were studied. It measured weight, height, waist circumference (WC), hip circumference (HP), thigh circumference (TC) and calculated body mass index (BMI), body adiposity index (BAI), waist to hip ratio (WHR) and waist to thigh ratio (WTR). There was also a performance of biochemical tests of lipid profile and fasting glucose. Systemic blood pressure was measured. The criteria proposed by the National Cholesterol Education Program III (NCEP-ATP III) to metabolic syndrome classification was used. Individuals were divided in groups with or without metabolic alterations and their anthropometric indicators were compared. Receiver operating characteristic (ROC) curves were designed for each anthropometric indicator using the metabolic syndrome classification to identify sensitivity and specificity. RESULTS: WC was a good tool to identify each metabolic disorder separately: total cholesterol (only females, p<0.05), triglycerides (only males, p<0.001), HDL cholesterol (p<0.05), LDL cholesterol (p<005) and fasting glycemic (p<005). WC also showed the best performance to identify metabolic syndrome in both genders (areas under the curve (AUCs): 0.79 and 0.76 for male and female, respectively), while BAI proved to be an inadequate indicator (AUCs: 0.63 and 0.67 for males and females), respectively, in this population. CONCLUSIONS: The central adiposity measure (WC) had the best performance to identify metabolic syndrome, and it is a convenient, cheap and reliable tool that can be used in clinical practice routinely to prevent cardiovascular complications in HIV patients.

RESUMO

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.

RESUMO

Cross-sectional study with the aim to evaluate self-care in people with type 2 diabetes mellitus and verify its relationship with sociodemographic and clinical characteristics. The sample included 218 patients under outpatient follow-up. Self-care activities were evaluated by means of a questionnaire that was previously translated and validated for Brazil. The questionnaire items that reached the highest means were related to drug therapy, whereas those with the lowest means were related to the practice of physical activity. Age correlated inversely with physical activity and foot care, and elapsed time since the disease diagnosis showed a direct correlation with blood glucose monitoring. Data showed that self-care activities related to behavioral changes are the ones that require greater investments to achieve its goals, and age and time since diagnosis should be considered in the planning of nursing care for people with diabetes mellitus.


Estudio transversal que buscó evaluar actividades de autocuidado con el diabetes mellitus tipo 2 y verificar su relación con características sociodemográficas y con datos clínicos. La muestra se constituyó de 218 personas en seguimiento ambulatorio. Las actividades de autocuidado fueron evaluados utilizando un cuestionario traducido y validado en Brasil. Los elementos de este cuestionario que tuvieron los promedios más altos se relacionan con la terapia con medicamentos, y los menores con la actividad física. Edad inversamente correlacionada con la actividad física y el cuidado de los pies, y el momento del diagnóstico mostró una correlación directa con la monitorización de la glucosa. Los datos mostraron que las actividades de autocuidado relacionadas con los cambios de comportamiento son las que requieren mayores inversiones para alcanzar los objetivos de la atención, y la edad y el diagnóstico de tiempo deben ser considerados en la planificación de los cuidados de enfermería a la persona con el diabetes mellitus.

RESUMO

BACKGROUND/AIMS: micronutrient deficiency may contribute to a poorer control of diabetes. Thus, the objective of the present study was to assess the urinary excretion of micronutrients in patients with type 2 diabetes mellitus. METHODS: patients with diabetes and controls were assessed regarding food intake, anthropometry, urinary loss of micronutrients and compared by the nonparametric Mann-Whitney test (p < 0.05). RESULTS: nine diabetic volunteers (52 ± 14 years, BMI 30 ± 11 kg/m² and abdominal circumference (AC) of 99 ± 25 cm) and 9 control individuals (51 ± 16 years, BMI 26 ± 5 kg/m² and AC of 90 ± 13 cm) were studied. Higher iron excretion was observed in the diabetic group and higher magnesium excretion in the control group. CONCLUSIONS: the type 2 diabetic patients here studied did not show increased micronutrient excretion in urine when compared to controls.


Introducción/objetivos: la deficiencia de micronutrientes puede contribuir a un menor control de la diabetes. El objetivo de este estudio fue evaluar la excreción urinaria de micronutrientes en pacientes con diabetes mellitus tipo 2. Métodos: los pacientes con diabetes y los controles fueron evaluados por la ingesta de alimentos, la antropometría, la pérdida urinaria de micronutrientes y comparados por Mann Whitney no paramétrico (p < 0,05). Resultados: fueron evaluados nueve sujetos diabéticos (52 ± 14 años con un IMC de 30 ± 11 kg/m² y la circunferencia de la cintura (CC) de 99 ± 25 cm) y nueve sujetos control (51 ± 16 años, IMC 26 ± 5 kg/m² y CA total de 90 ± 13 cm). La excreción de hierro más alta se observó en el grupo diabético y la mayor excreción de magnesio en el grupo de control. Conclusiones: el tipo 2 de pacientes diabéticos estudiados aquí no mostraron un aumento en la excreción de micronutrientes en la orina en comparación con los controles.
