Abdominal fat quantity and distribution in women with polycystic ovary syndrome and extent of its relation to insulin resistance.
2007
Composizione corporea in relazione alla sindrome dell'ovaio policistico. Increased abdominal fat has been linked to insulin resistance and increased cardiovascular risk. Because many patients with polycystic ovary syndrome (PCOS) present abdominal obesity, it may be the cause of insulin resistance in this disorder.Setting: Fat quantity and distribution were evaluated by dual x-ray absorptiometry at the Departments of Clinical Medicine at the University of Palermo and the University of Naples, Italy.Patients: A total of 110 patients with PCOS and 112 weight-matched controls were studied. Anthropometric data, blood glucose, serum insulin, and testosterone were evaluated. Total, trunk, and cen…
Criss‐crossing autism spectrum disorder and adult neurogenesis
2021
Autism spectrum disorder (ASD) comprises a group of multifactorial neurodevelopmental disorders primarily characterized by deficits in social interaction and repetitive behavior. Although the onset is typically in early childhood, ASD poses a lifelong challenge for both patients and caretakers. Adult neurogenesis (AN) is the process by which new functional neurons are created from neural stem cells existing in the post-natal brain. The entire event is based on a sequence of cellular processes, such as proliferation, specification of cell fate, maturation, and ultimately, synaptic integration into the existing neural circuits. Hence, AN is implicated in structural and functional brain plasti…
Dietary and physical activity counselling on Type 2 diabetes and impaired glucose tolerance by physicians and nurses in primary healthcare in Finland
2006
To investigate the initiation of dietary and physical activity counselling and the arguments used when discussing physical activity and the type and consumption of dietary fats, during nurse-patient and physician-patient diabetic lifestyle counselling.This study is a part of a larger follow-up research project focusing on diabetes counselling. The data include 129 videotaped counselling sessions between 17 patients and their physicians and nurses. Content analysis was carried out by identifying the verbal comments and reactions of participants concerning both physical activity and the type and consumption of dietary fats.The physicians and nurses spent little time on dietary and physical ac…
Changes in body composition, physical performance and cardiovascular risk factors after a 3-week integrated body weight reduction program and after 1…
2005
To investigate the short- and medium-term (ie, at 1-y follow-up) effects of a hospital-based body weight reduction (BWR) program lasting 3 weeks in severely obese individuals.Longitudinal, clinical intervention study entailing energy-restricted diet, tailored aerobic-strength exercise, psychological counselling and nutritional education during a 3-week period followed by 49 weeks of indirect supervision at home.In all, 45 women and 19 men aged 30.2 +/- 7.2 y (mean +/- s.d.) with severe obesity (BMI: 41.3 +/- 4.3 kg/m(2)), classified as weight losers (finalinitial weight) and regainers (finalor =initial weight).Body composition, physical performance and cardiovascular risk factors before and…
Comparison of glycemic response and insulin requirements after mixed meals of equal carbohydrate content in healthy, type-1, and type-2 diabetic man
1989
The postprandial insulin requirements after three mixed meals of equal carbohydrate and energy content were assessed in 10 type-1 and 12 type-2 diabetics by a glucose-controlled insulin infusion system. These were compared with the glycemic response to the same meals of 10 healthy individuals (glycemic index). In type-1 diabetics, we found the highest insulin requirements after consumption of a continental breakfast (low fibre, low protein, high fat). Ten percent less insulin was infused after milk (low fat, high protein) and 30% less after an English breakfast (high fibre, high protein). Type-2 diabetics showed no significant differences in insulin requirements between the three test meals…
Subcutaneous and omental fat expression of adiponectin and leptin in women with polycystic ovary syndrome
2007
Objective To assess message expression of adiponectin and leptin in visceral and SC fat in women with polycystic ovary syndrome (PCOS) and in control women. Design Prospective clinical trial. Setting Academic medical centers in Mexico City, Mexico and New York, New York. Patient(s) Women with PCOS and control women. Intervention(s) Surgical biopsies of visceral (omental) and subcutaneous (SC) adipose tissue, fasting blood samples, and ultrasound measurements of visceral and SC fat. Main Outcome Measure(s) Messenger RNA assessment of adiponectin and leptin in adipose tissue samples; serum measurements of adiponectin, leptin, glucose, insulin, and hormone levels; measurements of fat quantity …
Effect of neuromuscular electrical stimulation frequency on postprandial glycemia, current-related discomfort, and muscle soreness. A crossover study
2019
Consensus is lacking regarding optimal neuromuscular electrical stimulation (NMES) parameters for postprandial glycemic control. Therefore, the aim of this study was to determine the NMES frequency inducing the greatest hypoglycemic effect in healthy individuals. The secondary aim was to compare current-related discomfort and muscle soreness between different frequencies. We conducted an experimental clinical study with a randomized crossover design. Sixteen healthy and sedentary participants received NMES for 20 min at 5, 10, or 50 Hz (pulse duration: 400 μs, on-off ratio: 4:12 s) following a standardized meal. Glycemia, discomfort, and muscle soreness during and after NMES were compared …
Glucose but Not Protein or Fat Load Amplifies the Cortisol Response to Psychosocial Stress
2002
We previously reported that glucose intake amplifies cortisol response to psychosocial stress and smoking in healthy young men, while low blood glucose levels prevented the stress-induced activation of the hypothalamus pituitary adrenal (HPA) axis. However, it remains unknown whether this modulation is specific for glucose load or a more common effect of energy availability. To elucidate this question, 37 healthy men, who fasted for at least 8 h before the experiment, were randomly assigned to four experimental groups, who received glucose (n = 8), protein (n = 10), fat (n = 10), and water (n = 9), one h before their exposure to the Trier Social Stress Test (TSST). Blood glucose levels were…
Salivary composition in obese vs normal-weight subjects: towards a role in postprandial lipid metabolism?
2015
In the pathophysiological context of obesity, oral exposure to dietary fat can modulate lipid digestion and absorption but underlying in-mouth mechanisms have not been clearly identified. Therefore we tested the hypothesis that salivary components related to dietary fat sensitivity would differ according to BMI and postprandial lipid metabolism in young men. Saliva was collected from 9 normal-weight (BMI=22.3±0.5 kg/m2) and 9 non-morbid obese (BMI=31.7±0.3 kg/m2) men before a 8 h-postprandial metabolic exploration test involving the consumption of a 40 g fat-meal, in which obese subjects revealed a delayed postprandial lipid metabolism. Nine salivary characteristics (flow, protein content, …
Pasta consumption and connected dietary habits: Associations with glucose control, adiposity measures, and cardiovascular risk factors in people with…
2019
Background: Pasta is a refined carbohydrate with a low glycemic index. Whether pasta shares the metabolic advantages of other low glycemic index foods has not really been investigated. The aim of this study is to document, in people with type-2 diabetes, the consumption of pasta, the connected dietary habits, and the association with glucose control, measures of adiposity, and major cardiovascular risk factors. Methods: We studied 2562 participants. The dietary habits were assessed with the European Prospective Investigation into Cancer and Nutrition (EPIC) questionnaire. Sex-specific quartiles of pasta consumption were created in order to explore the study aims. Results: A higher pasta con…
