Abstract
OBJECTIVE The Advanced Hybrid Closed Loop (AHCL) systems have provided the potential to ameliorate glucose control in children with Type 1 Diabetes. The aim of the present work was to compare metabolic control obtained with 2 AHCL systems (Medtronic 780G system and Tandem Control IQ system) in a pediatric real-life clinical context. RESEARCH DESIGN AND METHODS It is an observational, real-life, monocentric study; thirty one children and adolescents (M:F = 15:16, age range 7.6-18 years, mean age 13.05 ± 2.4 years, Diabetes duration > 1 year) with T1D, previously treated with Predictive Low Glucose Suspend (PLGS) systems and then upgraded to AHCL have been enrolled. CGM data of the last four weeks of "PLGS system" (PRE period) with the first four weeks of AHCL system (POST period) have been compared. RESULTS For both AHCL systems, Medtronic 780G and Tandem Control IQ, respectively TIR at 4 weeks significantly increased, from 65.7 to 70.5% (p < 0.01) and from 64.8 to 70.1% (p < 0.01). (p < 0.01). The comparison between CGM metrics of the 2 evaluated systems doesn't show difference at baseline (last four weeks of PLGS system) and after four weeks of AHCL use. CONCLUSIONS To our knowledge, this study is the first real-life one comparing 2 AHCL systems in a pediatric population with T1D. It shows an improvement in glucose control when upgrading to AHCL. The comparison between the two AHCL systems did not show significant differences in the analyzed CGM metrics, meaning that the algorithms currently available are equally effective in promoting glucose control.

Abstract
Treatment of adolescents with growth hormone deficiency (GHD) during the transition period is a controversial issue. This paper is a contribution from the Italian community of paediatric and adult endocrinologists surveyed in a Delphi panel. The Delphi method is a structured communication technique, originally developed as a systematic, interactive forecasting method that relies on a panel of experts. The experts answer questionnaires in two or more rounds. There was substantial agreement on the definition of the problems associated with the diagnosis and treatment of adolescents with GHD in the transition period, as well as on the identification of the controversial issues which need further studies. There is general consensus on the need of re-testing all isolated idiopathic GHD after at least 30-day withdrawn from treatment, while in patients with multiple pituitary deficiency and low IGF-I levels there is generally no need to re-test. In patients with permanent or confirmed GHD, a starting low rhGH dose (0.01-0.03 mg per day) to be adjusted according to IGF-I concentrations is also widely accepted. For those continuing treatment, the optimal therapeutic schedule to obtain full somatic maturation, normalization of body composition and bone density, cardiovascular function and Quality of Life, need to be evaluated.

Abstract
Streptococcus pneumoniae (pneumococcus) is a bacterium responsible for a wide spectrum of illnesses. The surface of the bacterium consists of three distinctive membranes: plasmatic, cellular and the polysaccharide (PS) capsule. PS capsules may mediate several biological processes, particularly invasive infections of human beings. Prevention against pneumococcal related illnesses can be provided by vaccines. There is a sound investment worldwide in the investigation of a proteic antigen as a possible alternative to pneumococcal vaccines based exclusively on PS. A few proteins which are part of the membrane of the pneumococcus seem to have antigen potential to be part of a vaccine, particularly the PspA. A vital aspect in the production of the intended conjugate pneumococcal vaccine is the efficient production (in industrial scale) of both, the chosen PS serotypes as well as the PspA protein. Growing recombinant Escherichia coli (rE. coli) in high-cell density cultures (HCDC) under a fed-batch regime requires a refined continuous control over various process variables where the on-line prediction of the feeding phase is of particular relevance and one of the focuses of this paper. The viability of an on-line monitoring software system, based on constructive neural networks (CoNN), for automatically detecting the time to start the fed-phase of a HCDC of rE. coli that contains a plasmid used for PspA expression is investigated. The paper describes the data and methodology used for training five different types of CoNNs, four of them suitable for classification tasks and one suitable for regression tasks, aiming at comparatively investigate both approaches. Results of software simulations implementing five CoNN algorithms as well as conventional neural networks (FFNN), decision trees (DT) and support vector machines (SVM) are also presented and discussed. A modified CasCor algorithm, implementing a data softening process, has shown to be an efficient candidate to be part of an on-line HCDC monitoring system for detecting the feeding phase of the HCDC process.

Abstract
OBJECTIVE To compare the use of GnRH agonist (GnRH-a) versus hCG in triggering the follicular rupture in patients with polycystic ovarian disease (PCOD) in whom ovulation was induced by gonadotropins. DESIGN Polycystic ovarian disease gonadotropin hyperstimulated cycles outcome was investigated in a prospective study. PATIENTS AND INTERVENTIONS Thirty-three PCOD patients (40 cycles) with gonadotropin-induced mild to moderate degree of ovarian hyperstimulation received 5,000 IU IM hCG or 200 microg [corrected] SC GnRH-a. A subgroup of GnRH-a-treated patients received P for luteal support. Five GnRH-a-treated patients underwent a GnRH test during luteal phase. MAIN OUTCOME MEASURES Echographic and endocrine characteristics both during the therapy and the luteal phase. RESULTS There was a similar percentage of ovulation and pregnancy rate in both groups of patients. The ovarian enlargement during the luteal phase in the GnRH-a-treated patients was lower than in the hCG group. Progesterone plasma levels (at midluteal phase) and the length of luteal phase was significantly lower in GnRH-a-treated patients with respect to the hCG-treated group. These differences disappeared in patients receiving luteal support. After GnRH injection, LH secretion decreased in GnRH-a-treated patients with respect to controls; however, corpus luteum was able to respond with a normal increase of P production. CONCLUSION The GnRH-a appears to be an effective alternative to hCG for inducing the follicular rupture in stimulated cycles in women who are at risk for developing ovarian hyperstimulation syndrome. However, GnRH-a administration can induce short luteal phase. This defect may be ascribed to the pituitary desensitization rather than to a direct effect on corpus luteum. Luteal phase support is needed to prevent luteal phase deficiency.

Abstract
Different prostaglandins (PG) seem to have luteolytic or luteotrophic function in relation to the phases of life of the human corpus luteum and in-vitro studies demonstrate a luteotrophic function of PGE2, PGI2, PGD2. The present study evaluated the effect of an inhibitor of prostaglandin synthesis on the hypophyseal and luteal responses to gonadotrophin-releasing hormone (GnRH) in women during the mid-luteal phase. Twenty normal menstruating women participated in the study. Two different protocols were applied. After monitored ovulation (day 0), eight patients were treated with indomethacin for 7 days and 12 untreated patients served as controls. To evaluate luteal progesterone production, blood samples were taken every 15 min for 2 h basally and after a bolus of GnRH (25 micrograms i.v.); eight control patients were also treated with indomethacin for one day, and the endocrine study was repeated. The long-term administration of indomethacin significantly reduced basal as well as luteinizing hormone (LH)-stimulated progesterone production by the corpus luteum in respect to controls. Short-term administration failed to influence basal progesterone production, but abolished its secretory response to LH. A luteotrophic role for prostaglandins in human luteal function is suggested.

Abstract
Ten patients with polycystic ovary disease (PCOD) had ovulation induction after pituitary suppression by gonadotropin releasing hormone agonist (GnRHa) with GnRHa plus pure follicle-stimulating hormone (FSH) or plus human menopausal gonadotropin (hMG). Duration of the stimulation period and gonadotropin doses were superimposable. A multifollicular response was observed in both treatments. Bioassay and radioimmunoassay of luteinizing hormone, androstanedione and testosterone plasma levels were higher in hMG cycles compared to FSH-treated cycles. No differences was found in FSH and estradiol (E2) plasma concentrations, whereas in hMG-treated cycles the E2/number of follicles and E2/ovarian volume ratios were greater than in the FSH-treated cycles. Clinical results in terms of percentages of ovulation and pregnancies were the same in the two protocols. We conclude that the presence of luteinizing hormone in induction of ovulation in patients with PCOD does not seem to influence follicular recruitment and development, but it may have a role in the enhancement of steroid production.

Abstract
To determine how starvation affects adrenal steroidogenesis we measured the activities of 3 adrenal enzymes involved in corticosterone biosynthesis in a group of adult female rats. The animals were either starved for 7 days or fed ad libitum for the same period. Relative adrenal weight and plasma corticosterone levels were increased in the experimental group of animals compared to the control group (40 +/- 2 vs 27 +/- 1 mg/100 g body weight, P less than 0.001, and 45 +/- 4 vs 30 +/- 5 ng/dl, P less than 0.05 respectively). There were no differences in plasma ACTH levels between the groups (34 +/- 5 vs 26 +/- 4 pg/ml). 11-Hydroxylase activity was increased in the starved group of animals (18 +/- 3 vs 8 +/- 2 nmol/mg protein/min, P less than 0.01). 3 beta-Hydroxysteroid dehydrogenase and 21-hydroxylase activities were not different between the groups (19 +/- 2 vs 16 +/- 1 nmol/mg protein/min, and 100 +/- 10 vs 110 +/- 10 pmol/mg protein/min respectively). These results suggest that acute starvation in rats produces an increase in adrenal 11-hydroxylase activity.

Abstract
The pattern of GH secretion during a continuous 4-h iv infusion of 1 microgram/kg.h GH-releasing hormone (1-44)-NH2 (GHRH-44) or saline was examined in 15 adult men. There was prompt release of GH beginning within 20 min of starting the GHRH-44 infusions, reaching peak GH levels of 43 +/- 11 (+/- SE) ng/ml within 60-90 min. This is similar to the peak GH level reached in men after a single 1 microgram/kg GHRH iv bolus dose (34 +/- 8 ng/ml). GH levels then fell progressively, but did not return to baseline during the GHRH infusions. After GHRH infusions, the response (delta) to a 1 microgram/kg GHRH bolus dose was markedly attenuated (delta GH, 2.7 +/- 0.9 ng/ml) compared to the response (delta GH, 23 +/- 3 ng/ml) after saline infusion. Dispersed rat pituicytes perifused with medium containing 10 nM GHRH-44 responded with an initial rapid rise in GH secretion, followed by a progressive decline, and after 150 min of continuous GHRH exposure, the response to pulses of an equal or higher (100 nM) GHRH concentration was blunted. These results indicate that the peak response to GHRH infusions is similar to that of maximally effective bolus doses; during infusions, the GH response is not sustained; and immediately after GHRH infusions, the response to previously effective bolus doses is reduced. These phenomena could reflect either receptor-mediated desensitization, the depletion of rapidly releasable GH stores, or both. A counterregulatory rise in hypothalamic somatostatin secretion is not necessary to produce these effects, since the same phenomenon occurs in vitro and in vivo.
