Abstract
BACKGROUND In Italy, the utilization and the reimbursement of Growth Hormone (rGH) therapy by the National Health System (Servizio Sanitario Nazionale) are regulated by the "Note #39" included in the "Notes for the use of drugs" by the Italian Medicines Agency (AIFA), which are published in the Official Gazette, thus having the force of law. The "Note #39" establishes the diagnosis for which the reimbursement is granted and confirms the assignment of the national health surveillance on the use of GH therapy to the Italian National Institute of Health, requesting its computerization. AIM The aim of this work was to realize a dedicated electronic Clinical Report Form based on the mandatory data requested by the Note #39 and allowing the online reporting of the rGH prescriptions by the regional accredited centers. RESULTS AND CONCLUSIONS This interface is at the base of the national database of the Italian Registry of GH Treatment, which allows obtaining and managing correct and complete data to provide public health surveillance on GH therapy, both at national and local levels, necessary for policymakers decisions. In addition, this national database could be a useful instrument for improving knowledge about aspects of this treatment still under discussion.

Abstract
Chondroitin sulfate/dermatan sulfate (CS/DS) were isolated and purified for the first time from the bone of corb (Sciaena umbra) (CBG) and their chemical composition and anticoagulant activity were assessed. Infrared spectrum and agarose-gel electrophoresis for extracted CS/DS were also investigated. The results showed that the purified CS/DS obtained at a yield of 10% contains about 31.28% sulfate and an average molecular mass of 23.35 kDa. Disaccharide analysis indicated that CBG was composed of monosulfated disaccharides in positions 6 and 4 of the N-acetylgalactosamine (8.6% and 40.0%, respectively) and disulfated disaccharides in different percentages. The charge density was 1.4 and the ratio of 4:6 sulfated residues was equal to 4.64. Chondroitinase AC showed that the purified CS/DS contained mainly 74% CS and 26% DS. Moreover, the new CS/DS extracted from bone of corb showed a strong anticoagulant effect through activated partial thrombosis time (aPTT), thrombin time (TT) and prothrombin time (PT). In fact, CBG prolonged significantly (p < 0.05), aPTT and PT about 2.62 and 1.26 fold, respectively, greater than that of the negative control at a concentration of 1000 μg/mL. However, TT assay of CBG was prolonged 3.53 fold compared with the control at 100 μg/mL. The purified CS/DS displayed a promising anticoagulant potential, which may be used as a novel and soothing drug.

Abstract
BACKGROUND While some information on psoriasis impact on pregnancy is available, very little is known on the preoccupations of women afflicted by the disease or on the dermatologists' (D) positioning as to psoriasis and pregnancy. The 'Objectifs Peau' project demonstrated a 4.7% prevalence of psoriasis in women aged 18-45 years in France. OBJECTIVE This project sought to further address these issues in view of a targeted action plan. METHODS A questionnaire was made available to 361 D of different types. RESULTS Overall, 152 D answered the questionnaire, 50.7% working in private or mixed practice and 49.3% in hospitals, with 63% females (DF) and 37% males (DM). Over the last 3 months, the mean percentage of women of child-bearing age seen by these D was 28.6%. The main issue addressed by D upon psoriasis diagnosis was the patient's wish to become pregnant in the short-term (84%), while the compatibility of drug treatment with pregnancy was the issue prioritized by patients (64%). Among DM and DF, 46% and 29% reported having been confronted with an unplanned pregnancy, with their reaction mainly dependent on the treatment taken in 66%. Regarding follow-up, 26% D declared having shared their decision-making with gynaecologists, while 56% considered the first pregnancy trimester to be the highest-risk period. Only 28% D were familiar with existing recommendations, with only 21% of them considering them appropriate. CONCLUSION Overall, 26.2% of French psoriasis women are of child-bearing potential, in line with our dataset (28.6%). Only 56% D considered the 1st pregnancy trimester to be the highest-risk period, with only one-third familiar with existing recommendations. The gap between recommendations and actual practices must be addressed through policies that take women's preoccupations better into account.

Abstract
Objective: In this pilot study, we report the composition, structure and properties of glycosaminoglycans (GAG) present in milk samples of various countries and ethnicities.Methods: Fifty samples of human milk were analyzed, 10 from east Europe, 10 from North Africa, 10 from Central Africa, 10 from South America and 10 from Asia. Moreover, 30 samples were obtained during the first week and 20 between 8 to 30 days of life.Results: Overall, no significant differences were observed for the qualitative composition of GAGs, mainly chondroitin sulfate, heparan sulfate and hyaluronic acid, comparing the mothers from the various countries and between the 30 milks obtained during the first week and the 20 samples collected thereafter. Moreover, no significant differences in human milk GAGs within the different groups analyzed belonging to various counties and ethnicities were observed.Conclusions: These results may be of useful, as in the case of pilot studies with infant formulas enriched with chondroitin sulfate (CS) and/or heparan sulfate (HS) necessary to verify their possible positive effects on newborns feeding in countries at high risk of infection and/or infestation.

Plasma Glycosaminoglycans as Diagnostic and Prognostic Biomarkers in Surgically Treated Renal Cell Carcinoma. Eur Urol Oncol 2018; 1:364-377.

Abstract
BACKGROUND Plasma glycosaminoglycan (GAG) measurements, when aggregated into diagnostic scores, accurately distinguish metastatic clear-cell renal cell carcinoma (RCC) from healthy samples and correlate with prognosis. However, it is unknown if GAG scores can detect RCC in earlier stages or if they correlate with prognosis after surgery. OBJECTIVE To explore the sensitivity and specificity of plasma GAGs for detection of early-stage RCC and prediction of recurrence and death after RCC surgery. DESIGN, SETTING, AND PARTICIPANTS This was a retrospective case-control study consisting of a consecutive series of 175 RCC patients surgically treated between May 2011 and February 2014 and 19 healthy controls. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Plasma GAGs in preoperative and postoperative RCC and healthy samples were measured using capillary electrophoresis with laser-induced fluorescence in a single blinded laboratory. A discovery set was first analyzed to update the historical GAG score. The sensitivity of the new GAG score for RCC detection versus healthy subjects was validated using the remaining samples. The correlation of the new GAG score to histopathologic variables, overall survival, and recurrence-free survival was evaluated using nonparametric and log-rank tests and multivariable Cox regression analyses. RESULTS AND LIMITATIONS The RCC cohort included 94 stage I, 58 stage II-III, and 22 stage IV cases. In the first discovery set (n=67), the new GAG score distinguished RCC from healthy samples with an area under the receiver operating characteristic curve (AUC) of 0.999. In the validation set (n=108), the GAG score achieved an AUC of 0.991, with 93.5% sensitivity. GAG scores were elevated in RCC compared to healthy samples, irrespective of and uncorrelated to stage, grade, histology, age, or gender. The total chondroitin sulfate concentration was an independent prognostic factor for both overall and recurrence-free survival (hazard ratios 1.51 and 1.25) with high concordance when combined with variables available at pathologic diagnosis (C-index 0.926 and 0.849) or preoperatively (C-index 0.846 and 0.736). Limitations of the study include its retrospective nature and moderate variability in GAG laboratory measurements. CONCLUSIONS Plasma GAGs are highly sensitive diagnostic and prognostic biomarkers in surgically treated RCC independent of stage, grade, or histology. Prospective validation studies on GAG scores for early detection, prediction, and surveillance for RCC recurrence are thus warranted. PATIENT SUMMARY In this study, we examined if a new molecular blood test can detect renal cell carcinoma in the early stages and predict if the cancer might relapse after surgery. The trial is registered on ClinicalTrial.gov as NCT03471897.

Abstract
Chondroitin sulfate was extracted from the cartilage of smooth hound (CSSH) and then purified by anion exchange chromatography. The structual characteristic of CSSH was evaluated by acetate cellulose electrophoresis, FTIR, 13C NMR and SAX-HPLC. Molecular weight of CSSH was average 68.78 KDa. Disaccharide analysis indicated that CSSH was predominately composed of monosulfated disaccharides in position 6 and 4 of the N-acetylgalactosamine (45.34% and 32.49%, respectively). CSSH was tested for in vitro anticoagulant activity using the three classical coagulation assays (activated partial thromboplastin time (aPTT), prothrombine time (TT) and thrombin time (PT) tests). The finding showed that CSSH prolonged significatively (p < 0.05), aPTT, TT and PT about 1.4, 3.44 and 1.21 fold, respectively, greater than that of the negative control at a concentration of 100 μg/ml. The CSSH caused a significant antiproliferative activity against HCT116 cell, which was 79% of cell proliferation inhibition at the concentration of 1000 μg/ml. Further, CSSH presented no toxicity against the normal cells and no hemolysis towards bovine erythrocytes for all concentrations tested. CSSH demonstrated hopeful antiproliferative and anticoagulant potential, which may be used as a novel and effective drug.

Abstract
Chondroitin sulfate/dermatan sulfate (CS/DS) was extracted from Atlantic bluefin tuna (Thunnus thynnus) skin (SGAT) and was purified and characterized. SGAT was characterized by acetate cellulose electrophoresis, FTIR spectroscopy, 13C NMR spectroscopy and SAX-HPLC. According to the results obtained for specific chondroitinases (ABC and AC) and the SAX-HPLC separation of generated unsaturated repeating disaccharides, the polymer was found to contain a disaccharide monosulfated in positions 6 and 4 of GalNAc and disulfated disaccharides in different percentages. These results were confirmed by 13C NMR experiments. The average molecular mass was 24.07 kDa, as determined by PAGE analysis. SGAT was evaluated for its in vitro anticoagulant activity via activated partial thromboplastin time, thrombin time and prothrombin time tests. The polymer showed strong inhibitory activity against angiotensin I-converting enzyme (IC50 = 0.25 mg mL−1). Overall, the results suggest that this newly extracted CS/DS can be useful for pharmacological applications. Chondroitin sulfate/dermatan sulfate (CS/DS) was extracted from Atlantic bluefin tuna (Thunnus thynnus) skin (SGAT) and was purified and characterized.![]()
