ABSTRACT
INTRODUCTION: Psychological vulnerability is a relevant component of polycystic ovarian syndrome (PCOS), but it is still under-explored, especially during adolescence. The aim of this study was to describe a selection of psychometric characteristics in a clinical sample of Italian adolescents with PCOS. Moreover, we reported the associations of body image, eating attitudes, and mood with metabolic features. METHODS: Our sample included 128 adolescent girls (age range: 14-19 years) with PCOS. Validated psychometric questionnaires were administered: State Anxiety Inventory (STAI), Beck Depression Inventory (BDI), Body Attitude Test (BAT), Bulimia Investigation Test (BITE), Eating Attitudes Test (EAT), and Perceived Stress Scale (PSS). RESULTS: Anxiety was the most prevalent mood disorder (63.1% trait anxiety and 57% state anxiety). Our cohort also showed a high prevalence of depression (39.1%), body image dissatisfaction (49.2%), disordered eating (11.7%), and bulimic risk (41.4%). PCOS adolescents with obesity and insulin resistance (IR) had statistically significant higher body image distress compared to those with normal weight and without IR (p < 0.001). The Sobel test for mediation showed that body image dissatisfaction mediates the relationship between state anxiety and bulimic risk (Z = 3.42, p < 0.001) and between depression and bulimic risk (Z = 4.59, p < 0.001). CONCLUSIONS: A considerable number of patients with PCOS experience psychological disorders during adolescence. IR and obesity play a role in the distress associated with body image, further contributing to psychological vulnerability, especially in the bulimic domain. A comprehensive biopsychosocial approach in adolescents with PCOS represents the basis for effectively managing and preventing complications arising from both psychological and biological disorders in adulthood.
ABSTRACT
OBJECTIVES: First trimester miscarriage is a multifactorial event. Various angiogenic factors have been proposed as possible early markers of non-viable pregnancies. The aim of the present study was to evaluate the systemic nitric oxide (NO) production in healthy early pregnancy and its possible role in first trimester miscarriage. STUDY DESIGN: We prospectively enrolled women referred to our Unit for elective termination of pregnancy, threatened abortion or missed abortion. Blood samples were taken for testing circulating NO plasma levels. Subsequently, all patients underwent 2-D ultrasonographic analysis and Color Doppler imaging to assess the pulsatility index of the uterine arteries. 3-D ultrasonographic and power Doppler analysis allowed a volumetric and vascular reconstruction of the placenta. During dilatation and vacuum aspiration, amniotic fluid was collected. RESULTS: Seventy-two patients were enrolled: 25 with elective termination of pregnancy (Group I); 17 with threatened abortion (Group II); 30 with missed abortion (Group III). Group II showed greater placental volume and lower uterine arteries PI than others. The plasma NO concentration resulted statistically higher in women with threatened abortion, while amniotic fluid NO concentration were higher in the viable pregnancies (Group I) than in the aborted fetuses (Group III). Plasma NO was inversely correlated with both mean arterial pressure and uterine artery PI and was positively correlated with amniotic fluid NO and CRL; amniotic fluid NO was positively correlated with placental Vascularization Index and Vascularization-Flow Index. CONCLUSION: Amniotic NO concentration was higher in viable pregnancies and positively related to Doppler 3D indices of vascularization and blood flow within the placenta. Further studies are needed to elucidate its role in first trimester miscarriage.
