Long-Term Effects of a Ketogenic vs a Hypocaloric Diet in Children and Adolescents with Obesity

Partsalaki Ioanna , Karvela Alexia , Spiliotis Bessie E

Background: The prevalence of childhood obesity is high worldwide and predisposes to adult obesity and metabolic disorders. Many dietary approaches have been proposed to reduce this prevalence, but no single diet has proven to be superior to others in terms of long-term weight loss maintenance in children.Objective and hypotheses: To evaluate and compare long-term body weight changes among obese children and adolescents who had lost at least 10% of their...

Background: In adults, insulin resistance is associated with vascular damage and progressive loss of the endothelial protective functions. Additionally, it further complicates the micro- and macro- vascular environment through increasing oxidative stress and inflammation.Aim: The purpose of this study was to evaluate how apoptosis and antioxidant markers are correlated with biochemical markers in children, during the glucose tolerance te...

Pro-Inflammatory (M1) and Anti-Inflammatory (M2) Profiles in Adipose Tissue of Lean and Obese Children and Adolescents

Karvela Alexia , Avgeri Aikaterini , Vlotinou Eleni D , Georgiou George , Papachristou Dionysios J , Spiliotis Bessie E

Background: Childhood obesity predisposes to metabolic disorders. Low grade inflammation of adipose tissue (AT) associated with macrophage infiltration may lead to metabolic complications. Two macrophage activation states M1 (pro-inflammatory) and M2 (anti-inflammatory) exist in AT with surface markers CD40 (M1), CD206 (M2) and CD163 (M2). M1 polarization correlates with metabolic complications.Objective and hypotheses: To study the expression of CD40, C...

Novel Uncoupling Protein 1 Expression in White Adipocytes of Subcutaneous Abdominal Adipose Tissue in Children and Adolescents: A Protective Mechanism for Metabolic Equilibrium?

Karvela Alexia , Avgeri Aikaterini , Vlotinou Eleni D , Georgiou George , Papachristou Dionysios J , Spiliotis Bessie E

Background: Morbid childhood obesity predisposes to metabolic disorders such as diabetes type 2. In mice, heat-producing ‘brown-like’ (beige) adipocytes can suppress weight gain and metabolic disease through the action of uncoupling protein 1 (UCP1) localized in the mitochondria.Objective and hypotheses: To study the expression of UCP1 in the adipose tissue of lean&obese children and adolescents.Method: Paraffin embed...

Serum Anti-Mullerian Hormone (AMH) concentrations and Reduced Appendix Testis Estrogen Receptor Expression in Cryptorchidism

Panagidis Antonios , Kourea Helen , Sinopidis Xenophon , Kostopoulou Eirini , Rojas-Gil Andrea Paola , Skiadopoulos Spyridon , Georgiou George , Spiliotis Bessie E.

Objective: AMH causes fetal paramesonephric duct regression and is involved in testicular development and function. Sertoli cell AMH remains high during childhood until puberty. The appendix testis (AT), a remnant of the paramesonephric duct, contains both androgen and estrogen receptors. AT androgen receptors have been reported to play a role in embryonic testicular descent. The AT is commonly resected during orchiopexy and abdominal surgery as possible torsion in the future ...
