Our study aims at evaluating clinical predictors of menstrual cycle disorders in female athletes who compete in running disciplines. This is a prospective observational study. Women were recruited between January and May 2022. 53 patients were enrolled and completed a questionnaire about menstrual cycle, physical activity and food habits characteristics. 39,6% of women in our population had menstrual irregularities and reported a significantly higher number of kilometres run per week (67 vs 35, p:0.02). The number of kilometres run per week was associated with menstrual irregularities (for 10 km, OR 1,35; IC95% 1,05-1,73; p: 0,02) after adjusting for BMI, age, level of sport and caloric intake. The variable of “km run per week” appeared as a diagnostic indicator of irregular menstrual cycle with statistical significance (AUC ROC curve 0,71, IC95% 0,54-0,86, p-value = 0,01) and the cut off-of 65 km run per week is a good indicator of the presence of irregular menstrual cycle (sensitivity (SE) and specificity (SP) of 55% and 81,48%). Menstrual cycle disorders are very frequent in female athletes and the variable of km run per week may have a role in screening endurance athletes at high risk for them.

Mini-puberty is the physiological and transient activation of the hypothalamic-pituitary-gonadal axis occurring during the first months after birth. In preterm infants, the hormonal surge is more pronounced and longer-lasting than in at-term-peers. To date, only few cases of vaginal bleeding in the setting of an exaggerated mini-puberty have been reported. At the corrected age of 3 months, an ex-very-preterm girl presented with breast enlargement and recurrent vaginal bleeding. A remarkable increase in gonadotropins and estradiol levels was detected, while pelvic ultrasound highlighted a large right ovarian cyst. As brain and pituitary MRI showed negative findings, an exaggerated mini-puberty was suspected and no additional investigations were undertaken. The subsequent progressive regression of clinical, biochemical and sonographic findings confirmed the diagnosis. Although exaggerated mini-puberty of infancy in ex-preterm girls is a rare event, it is important to raise knowledge of this para-physiological condition in order to avoid unnecessary investigations and treatment.

PURPOSE: While overexercise is commonly described in patients who experience anorexia nervosa (AN), it represents a condition still underestimated, especially in the paediatric population.METHOD: The present study aims at assessing the possible associations between levels of physical activity (PA) and clinical features, endocrinological data and psychopathological traits in a sample of 244 female adolescents hospitalised for AN subdivided into two groups according to PA levels (high PA vs. no/low PA). The two groups were compared through multivariate analyses, while multiple regression analysis was conducted to determine whether physical activity predict specific outcomes.RESULTS: No significant differences were found between the two groups in terms of last Body Mass Index (BMI) before illness, BMI at admission and disease duration, while a difference emerged in delta BMI(rapidity of weight loss), significantly higher in high-PA group (p=0.021). Significant differences were observed in Free triiodothyronine- (p<0.001), Free thyroxine (p=0.046), Follicle-stimulating hormone (p=0.019), Luteinising hormone (p=0.002) levels, with values remarkably lower in high-PA group. Concerning psychopathological scales, the high-PA group showed worst Children's Global Assessment Scale (CGAS) scores (p=0.035). Regression analyses revealed that higher PA predicts higher delta BMI (p=0.021), presence of amenorrhea (p=0.003), lower heart rate (p=0.012), lower thyroid (Free triiodothyronine p<0.001, Free thyroxine p=0.029) and gynaecological hormones' levels (Follicle-stimulating hormone p=0.023, Luteinising hormone p=0.003, 17-Beta estradiol p=0.041). Concerning psychiatric measures, HPA predicts worst scores at CGAS (p=0.019), and at scales for evaluation of alexithymia (p=0.028) and depression (p=0.004).CONCLUSIONS: Results suggest that high levels of physical activity in acute AN associate with worst clinical conditions at admission, especially in terms of endocrinological and

Ordered mesoporous silica nanoparticles (MSNs) were impregnated with different loadings of the luminescent complex tris(dibenzoylmethane) mono(1,10-phenanthroline)europium(III) (Eu(dbm)3phen), with the aim of increasing the luminescence by avoiding concentration quenching and having mainly in mind the application as spectral converter for multi-crystalline silicon solar cells. The morphological, structural and luminescence properties of the impregnated silica nanoparticles were characterized by N2 physisorption, X-ray diffraction, transmission electron microscopy, infrared spectroscopy, UV–visible spectroscopy and photoluminescence excitation and emission measurements. Photostability was tested under 1 sun (1000 W/m2) illumination for 24 h and the related effects were inspected by UV–visible and photoluminescence spectroscopies. Impregnation of the complex into 50–70 nm MSNs with pore size tailored around 2.9 nm depressed concentration quenching and allowed the use of complex loadings as high as 23 wt%. Sunlight irradiation caused a marked increase in the luminescence intensity.

Introduction and hypothesis The aim of this study was to evaluate the functional outcome of a single-incision sling procedure for the treatment of female stress urinary incontinence (SUI) and to correlate the cure rate with a pelvic floor ultrasound examination Methods Fifty-seven patients treated with a single-incision sling procedure between January 2009 and September 2010 were included in the study. Functional outcome was evaluated as objective cure rate assessed with stress test and subjective cure rate determined by the International Consultation on Incontinence-Short Form and Patient Global Impression of Improvement scores. Women underwent perineal ultrasound examination by a combined 2D translabial and 3D transvaginal approach to assess bladder neck and tape mobility, tape position along the urethral axis, and tape anchorage. According to the position of self-fixating tips, we divided patients into group A (both tips crossed the obturator membrane), group B (only one tip crossed the obturatormembrane) and group C (none of the tips crossed the obturator membrane). Objective cure rate and type of anchorage were compared with all ultrasound parameters. Results At an average follow-up of 13 months objective cure rate was 87.7 % with a significant subjective improvement. A significant difference in tape mobility was noted between group A and group C. Bladder neck mobility significantly increased in failures. Sling was significantly closer to midurethra in cured than in failures. Conclusions In 77 % of patients MA didn't reach the obturator membrane on both sides. This feature conditioned significantly bladder neck mobility but not the efficacy of the procedure. Tape position seems to be the most important factor for success. © The International Urogynecological Association 2013.
