High prevalence of diabetes has been previously reported in Japanese-Brazilians. In an attempt to better estimate the cardiometabolic risk, this study evaluated lipid disorders in 1,330 Japanese-Brazilians (46% men) aged >30 years. Hypercholesterolemia was defined as serum cholesterol > 240 mg/dL, hypertriglyceridemia as values > 150 mg/dL and low-HDL-C as values <40 mg/dL and <50 mg/dl for men and women respectively. The prevalence of dyslipidemias was compared by the chi-square test between gender and glycemic category. Mean and Standard Deviation […]

Osteoclastogenesis may be regulated via activation of the RANK/RANKL (receptor activator of nuclear factor-kappa B/ receptor activator of nuclear factor-kappa B ligand) system, which is mediated by osteoblasts. However, the bone loss mechanism induced by T3 (triiodothyronine) is still controversial. In this study, osteoblastic lineage rat cells (ROS 17/2.8) were treated with T3 (10-8 M, 10-9 M, and 10-10 M), and RANKL mRNA (messenger RNA) expression was measured by semiquantitative RT-PCR. Our results show that T3 concentrations used did not […]

The TNM classification of UICC is used for predicting the outcome of thyroid cancer. The 6th edition changed the description of primary tumor (T), regional lymph node (N) and the staging group. The aim of this study was to compare the ability of the 5th and the 6th editions to predict outcome. The two classifications were applied in a retrospective analysis of 90 patients from HUCFF. Sixty-nine patients had papillary carcinoma, 14 follicular, 4 Hürthle cell, and 3 mixed. Patients […]

The present study was designed to analyze the impact of the habitual physical activity determined by International Physical Activity Questionnaire (IPAQ) on lipid profile in representative sample of adults. A sample of 361 subjects (196 women and 165 men) aged 20

OBJECTIVE: To determine the clinical and laboratory parameters and the progression to insulin requirement in two groups of LADA patients separated according to GADA titers, and to evaluate the benefit of early insulinization in patients at high risk of premature beta-cell failure (high GADA titers). METHODS: Among the diabetic adults seen at our service and screened for GADA at diagnosis, 54 were diagnosed with LADA and classified as having low (> 1 U/ml and < 17.2 U/ml) or high (> […]

Macroprolactinemia is characterized by the predominance in the serum of macroprolactin, a prolactin (PRL) with high molecular mass and low biological activity that does not need treatment. The prevalence of macroprolactinemia was evaluated in 115 consecutive patients with hyperprolactinemia. Among them, 19 (16.5%) had solely macroprolactinemia, 4 (3.5%) polycystic ovary syndrome, 7 (6.1%) acromegaly, 8 (6.9%) idiopathic hyperprolactinemia, 10 (8.6%) primary hypothyroidism, 14 (12.2%) clinically non-functioning pituitary adenomas, 20 (17.4%) drug-induced hyperprolactinemia and 33 (28.7%) prolactinomas. The diagnosis of macroprolactinemia […]

Increased body mass index and waist circumference are related to cardiovascular risk factors. Leptin is an adipocyte-produced hormone and regulates body weight. Leptin is directly related to body fat. To evaluate the relationship between leptin and metabolic profile in obese subjects, we studied 119 patients. Anthropometric, laboratory, body composition (by bioelectrical impedance) and co-morbidity data were collected. The analysis was performed in the female population (86.6%): average age: 42 ± 13 years; hypertension, type 2 diabetes and grade III obesity […]

This study aimed to determine through a questionnaire applied to interviewers, the current or past use of anabolic androgenic steroids (AAS), as well as other hormones (OH), and other medicines (OM), food supplement and illicit drugs among strength training apprentices in the city of Porto Alegre, RS. We interviewed 288 subjects draw from a sample of 13 gyms. The prevalence of current and past use of AAS was about 11.1% (32/288), OH 5.2% (16/288) and OM 4.2% (12/288). The most […]

OBJECTIVE: To evaluate the positive predictive value of detectable Tg during T4 therapy (Tg on T4) in patients with thyroid cancer after total thyroidectomy and remnant ablation, discussing the work-up in this situation and the empirical indication of 131I. PATIENTS AND METHODS: Initially, 234 low-risk patients [tumor < 5cm, completely resected, no extensive extrathyroid invasion (pT4)] submitted to total thyroidectomy and ablation with 131I (3.7

OBJECTIVE: To evaluate the relationship between fat intake and serum cholesterol. METHODS: A survey was conducted in a probabilistic sample of students from public schools in Niterói, state of Rio de Janeiro, Brazil. Anthropometric data were collected on 610 youngsters, 573 of them had blood drown, and 539 answered a simplified questionnaire on fat intake. Multivariate linear regression included as confounders: parents’ cholesterolemia, adolescent age and body mass index (BMI). RESULTS: The prevalence of high concentrations (> 170 mg/dL) of […]

OBJECTIVES: To evaluate the impact of bariatric surgery on the metabolic syndrome (MS) and what are the criteria that contribute the most for its exclusion after surgery. The progress of leucometry was also analyzed. METHODS AND PROCEDURES: 47 obese women with MS were evaluated. All patients were operated with the Roux-en-Y vertical gastric bypass technique, with the insertion of a contention ring on the gastro-jejune anastomosis (Fobi-Capella). Patients were evaluated before and on the first year post-surgery. RESULTS: Fasting glucose […]

AIM: The focus of this study was to evaluate the metabolic profile of Prader-Willi Syndrome (PWS) patients treated with growth hormone. PATIENTS AND METHODS: Seven patients (four boys and three girls) with ages between six years and six months and 14 years and 11 months were treated with GH 0.1 U/kg/day subcutaneous by six times a week, for two years. Anthropometric data, lipids, glucose, IGF-I and body composition were evaluated at baseline and after 12 and 24 months. RESULTS: IGF-I […]
