The adiponectin levels may be involved in the mechanism responsible for high TG levels in obese and diabetic patients. These abnormalities can be reversed by RYGB.
The loss of estrogen with menopause is associated with an increase in central fat. The objective of this study was to evaluate the effects of menopause hormone therapy (HT) on body composition and metabolic parameters in postmenopausal women. A prospective study was conducted among postmenopausal women from the Climacteric clinic, Universidade Federal de São Paulo. Thirty-two participants, median age 51 years, were included. Sixteen women were eligible to receive a low-dose continuous combined HT, containing 1 mg of E2 plus 0.125 mg of trimegestone for 6 months. The other 16 women remained in the control group. In the HT group, significant decreases from baseline were evident for the total cholesterol (TC) (p < 0.05) and LDL levels (p < 0.05). The HDL significantly decreased (p < 0.05). However, the TC/HDL ratio also decreased (p = 0.05). The parameters of body composition, after 6 months of HT, were maintained. In the control group, body mass index levels increased from baseline, however, with nonstatistically significant differences (p = 0.06). Analyzing the body composition showed a significant increase in the trunk body fat (p = 0.04), trunk region fat (p = 0.04), and total region fat (p = 0.03) after 6 months. In conclusion, the present study provides evidence that HT can stunt the increase in total body fat and prevent the shift from a more central fat distribution observed in early postmenopausal period.
RESUMOA relação entre câncer e acromegalia tem sido objeto de estudo há muitos anos. A partir de um caso de carcinoma diferenciado de tireóide em um de nossos pacientes acromegálicos, estudamos uma série de 100 outros acromegálicos e encontramos dois outros casos de câncer de tireóide, descritos neste trabalho. A partir daí, levantamos os dados da literatura sobre esta última associação e sua possível patogênese. A prevalência de patologias tireoidianas é aumentada dentre os acromegálicos, às custas, principalmente, do bócio nodular. Esta associação será abordada, assim como a relação entre o fator de crescimento insulina símile I (IGF-I) e câncer, numa tentativa de entender melhor seu significado frente aos nossos casos. Nós concluímos que seria prudente realizar exame ultrassonográfico periódico em acromegálicos, seguido de Punção Aspirativa com Agulha Fina (PAAF) dos nódulos suspeitos. The relationship between cancer and acromegaly has been subject of study for many years. From a case of differentiated thyroid carcinoma in one of our acromegalic patients, we reviewed a series of 100 acromegalics and found two others cases of thyroid cancer, which are described in this work. From that point, we have got data from the literature about this last association and its possible pathogenesis. The prevalence of thyroid disease is increased among acromegalic patients, mainly due to nodular goiter. This association will be discussed, as well as the relation between insulin-like growth factor-I and cancer, in an effort to have a better understanding of its meaning for our cases. We concluded that it would be prudent to do periodic ultrasonografic evaluation of acromegalic patients, follow by fine needle aspiration biopsies of suspect nodules.
UM LARGO ESPECTRO DE MANIFESTAÇÕES clínicas sistêmicas caracteriza a acromegalia. Bócio, pólipos colônicos, número aumentado de papilomas cutâneos (skin tags) e hiperidrose são geralmente descritas ao diagnóstico, juntamente com crescimento exagerado das mãos e pés, e características faciais grosseiras.Neoplasias malignas são consideradas, em conjunto com doenças
