Introduction: The role of thyroxine (T4) during embryo development is recognised as crucial. The research question of this study was if embryo quality and reproductive outcomes after IVF are affected by maternal thyroid function and/or thyroid auto-immunity (TAI).Methods/design: We conducted a prospective study (ThyrART), assessing embryo quality and reproductive outcome of women undergoing ovarian stimulation with a flexible GnRH-antagonist p...

Introduction: The evidence of the impact of OS for IVF and thyroid function or autoimmunity is inconclusive, based mainly on assessments just before and after OS. The aim of this study was to closely monitor the changes on thyroid function and autoimmunity throughout OS for IVF.Description of methods/designs: In a prospective, interventional study, a flexible GnRH-antagonist protocol was applied to 42 women undergoing IVF ((classic or ICSI), with initiat...

Context: Evidence suggests that gabapentin, a γ-aminobutyric acid analogue, is effective in the treatment of hot flushes in women with natural or tamoxifen-induced menopause.Objective and design: To investigate the efficacy and tolerability of gabapentin for the treatment of menopausal hot flushes, a systematic review of all pertinent trials and a meta-analysis of those that were randomized placebo-controlled (RCT) were performed.<p class="abste...

Background: Conflicting results regarding adiponectin levels in women with polycystic ovary syndrome (PCOS) have been reported. To evaluate adiponectin levels in PCOS, a systematic review of all studies comparing adiponectin levels in women with PCOS to healthy controls and a meta-analysis of those involving women with similar Body Mass Index (BMI) were performed. Influence of possible effect modifiers, such as insulin resistance (IR) and testosterone, was investigated. Influe...

Introduction: Vitamin D concentrations during pregnancy are measured to diagnose states of insufficiency or deficiency. The aim of this study is to apply accurate assays of vitamin D forms (single hydroxylated (25(OH)D2, 25(OH)D3), double-hydroxylated (1α,25(OH)2D2, 1α,25(OH)2D3), epimers (3-epi-25(OH)D2, 3-epi-25(OH)D3)) in mothers (serum) and neonates (umbilical cord) i) to expl...

Introduction: Despite high levels of sunshine, maternal hypovitaminosis D during pregnancy is prevalent in the Mediterranean region, consisting a paradox. The aim of the study was to systematically review trials that investigated vitamin D concentrations during pregnancy in this region, in order to determine predictors of hypovitaminosis D and explain the paradox.Methods: After applying inclusion/exclusion criteria, 15 studies were entered into the syste...
