Ethnic differences in serum lipoproteins and their determinants in South African women.
2010
The objective of the study was to characterize ethnic differences in lipid levels and low-density lipoprotein (LDL) particle size and subclasses in black and white South African women and to explore the associations with insulin sensitivity (S(I)), body composition, and lifestyle factors. Fasting serum lipids and LDL size and subclasses, body composition (dual-energy x-ray absorptiometry), and S(I) (frequently sampled intravenous glucose tolerance test) were measured in normal-weight (body mass index25 kg/m(2)) black (n = 15) and white (n = 15), and obese (body mass index30 kg/m(2)) black (n = 13) and white (n = 13) women. Normal-weight and obese black women had lower triglycerides (0.59 +/…
Insulin receptors and insulin sensitivity in normo and hyperinsulinemic obese patients
1985
The authors have studied insulin receptors on peripheral blood monocytes and insulin sensitivity, evaluated by simultaneous infusion of glucose, insulin and somatostatin in 10 control subjects and in 20 obese patients with normal glucose tolerance. The obese patients have been divided into two groups, normo (NO) and hyperinsulinemic (HO), according to the total insulin response during OGTT. We considered HO patients with insulin response higher than M + 2DS of controls. Obese patients showed, in comparison to the controls, a lower specific binding and higher degree of insulin resistance. The subdivision of obese patients allowed us to distinguish two groups. The first was characterized by b…
Use of glargine in pregnant women with type 1 diabetes mellitus: a case-control study.
2008
BACKGROUND: Insulin glargine is a once-daily basal insulin analog with prolonged duration of action and absence of an evident peak. Glargine is associated with reduced frequency of hypoglycemic episodes (mostly nocturnal) as well as effective glycemic control. Maintenance of good metabolic control before conception and throughout pregnancy is essential to lower the risk of fetal malformations. Glargine might be a valuable alternative in the management of pregnancies complicated by diabetes mellitus. However, because its clinical utility has not been established, the use of glargine is not currently recommended during pregnancy. OBJECTIVE: The aim of this study was to retrospectively evaluat…
Placental infiltration of inflammatory markers in gestational diabetic women.
2013
Gestational diabetes mellitus (GDM) is pathology of glucose intolerance during pregnancy. It is influenced by maternal hyperglycemia and insulinemia through placental circulation. The study was undertaken to investigate the implication of pro-inflammatory factors in the placenta of GDM women. Thirty GDM women have delivered macrosomic babies, and 30 healthy age-matched pregnant women have delivered non macrosomic babies, were recruited in the study. The mRNAs encoding for IL-6, TLR4, TGF-β, CD68, CD14, EMR-1, CCL2, TCR-α, T-bet, GATA-3, leptin and adiponectin were quantified in placental samples by using RT-qPCR. The mRNA expression of the pro-inflammatory factors, i.e., IL-6, TLR4 and TGF-…
Pharmacotherapy for gestational diabetes mellitus: still insulin, or what about sulfonylureas?
2018
Randomized trials have not focused on neonatal complications of glyburide for women with gestational diabetes.To compare oral glyburide vs subcutaneous insulin in prevention of perinatal complications in newborns of women with gestational diabetes.The Insulin Daonil trial (INDAO), a multicenter noninferiority randomized trial conducted between May 2012 and November 2016 (end of participant follow-up) in 13 tertiary care university hospitals in France including 914 women with singleton pregnancies and gestational diabetes diagnosed between 24 and 34 weeks of gestation.Women who required pharmacologic treatment after 10 days of dietary intervention were randomly assigned to receive glyburide …
Visual-motion suppression in congenital pendular nystagmus.
2009
Patients with a congenital pendular nystagmus are known not to experience oscillopsia in a normal visual environment. The data of a 31-year-old female patient suffering from a congenital pendular nystagmus are presented. The aim of the fluorodeoxyglucose positron emission tomography (FDG-PET) experiment was to analyze the regional cerebral glucose metabolism (rCGM) during minimal as well as maximal nystagmus. Video-oculography showed a maximum in frequency of the horizontal pendular nystagmus during gaze to the left, whereas the zone of minimal nystagmus was 10 degrees to the right. Two sessions with an 18F-fluorodeoxyglucose tracer were performed to analyze cerebral blood-glucose utilizati…
Endothelial dysfunction in PCOS. role of obesity and adipose hormones
2006
PURPOSE: Polycystic ovary syndrome (PCOS) is an extremely prevalent disorder in which elevated blood markers of cardiovascular risk and altered endothelial function have been found. This study was designed to determine if abnormal carotid intima-media thickness (IMT) and brachial flow-mediated dilation (FMD) in young women with PCOS may be explained by insulin resistance and elevated adipocytokines. METHODS: A prospective study in 50 young women with PCOS (age: 25.2 +/- 1 years; body mass index [BMI]: 28.7 +/- 0.8) and 50 matched ovulatory controls (age: 25.1 +/- 0.7 years; BMI: 28.5 +/- 0.5) was performed. Carotid IMT, brachial FMD, and blood for fasting glucose, insulin, leptin, adiponect…
Prolonged breast-feeding protects mothers from later-life obesity and related cardio-metabolic disorders
2011
AbstractObjectiveTo investigate the long-term effects of duration of postpartum lactation on maternal body composition and risk for cardio-metabolic disorders in later life.DesignRetrospective study. Body composition was measured using dual-energy X-ray absorptiometry and serum glucose, insulin and lipids were analysed using enzymatic photometric methods 16–20 years after the last pregnancy. Medical history and lifestyle factors were collected via a self-administered questionnaire. Detailed information regarding weight change patterns during each pregnancy was obtained from personal maternity tracking records.SettingCity of Jyväskylä and surroundings in Central Finland.SubjectsTwo hundred a…
Hormone therapy is associated with better body composition and adipokine/glucose profiles
2012
Objective: The aim of this study was to evaluate the possibility of preventing the metabolic health consequences of postmenopausal hypogonadism with the use of long-term hormone therapy (HT). Methods: We used a monozygotic co-twin control design including 10 twin pairs (aged 56-62 y) discordant for HT (duration of HT, 2-10 y). In addition, 14 premenopausal women (aged 29-35 y) who did not use HT were studied to evaluate the differences in metabolic health between the premenopausal and postmenopausal states. Body composition was determined, and waist-to-hip ratio was used as an estimate for fat distribution. Serum sex steroids, sex hormone-binding globulin, and serum lipid and glucose profil…
Gender differences on oxidative stress markers and complement component C3 plasma values after an oral unsaturated fat load test
2020
Abstract Objective Post-prandial lipaemia (PL), oxidative stress (OS), and complement component C3 (C3) values are related to the atherosclerosis process. The post-prandial response of C3 after an oral fat load test (OFLT) using unsaturated fat is poorly addressed. The aim of this study was to analyze and compare the post-prandial response of OS markers and C3 values in men and women after an OFLT using unsaturated fat. Methods The study included a total of 22 healthy subjects with normal lipids and normal blood glucose (11 men and 11 pre-menopausal women). An oral unsaturated fat load test (OFLT: 50 g fat per m2 body surface) was performed using a commercial liquid preparation of long chai…
