Abstract
Study question
What is the impact of different static and dynamic organotypic culture systems on the outcome of prepubertal porcine immature testicular tissue (ITT) culture?
Summary answer
Using a hybrid silicone-agarose static culture system improves germ cell survival and differentiation in ITT ex-vivo.
What is known already
In mice, organotypic culture of ITT led to the birth of healthy fertile pups. In other larger mammals, including humans, it remains challenging to efficiently reproduce spermatogenesis ex-vivo. With the advent of tissue engineering, culture systems are becoming more complex to better mimic the in vivo environment by modifying and/or improving physical culture conditions (i.e. tissue perfusion, oxygen diffusion, direct/indirect contact with medium). Recent studies in rodents showed that by using hybrid static and dynamic silicone-based organotypic culture systems, the efficiency of spermatogenesis can be significantly improved. Such culture systems have not been reported in large mammals yet.
Study design, size, duration
Testes were collected from three 5-7 days old piglets as a by-product of castration for a Belgian farm. The fresh ITT fragments were immediately used for culture experiments. Fragments were cultured for a 30 days duration in the different static i.e. polytetrafluoroethylene membrane inserts (CT), agarose gel (AG) and agarose gel with polydimethylsiloxane cover (AGPC) and dynamic i.e. microfluidic (MF) systems using a single medium. The CT system served as control.
Participants/materials, setting, methods
Cultured ITT fragments were monitored every 4-5 days by serial imaging. Analyses were performed at days 0, 5, 10, 20 and 30. Seminiferous tubule (ST) integrity and diameters were evaluated on Periodic Acid Schiff-stained slides. Immunohistochemistry was used to identify: germ (PGP9.5, VASA, SYCP3, CREM), somatic (SOX9, INSL3) and proliferating (Ki67) cells and to assess oxidative stress (MDA) and apoptosis (C-Caspase3). Testosterone was measured using ELISA. A two-way ANOVA was used for statistical analyses.
Main results and the role of chance
All systems supported the survival, growth and maturation of ITT fragments in vitro. Between days 0 and 30, ST diameters increased in all systems (p < 0.000) (day 0: 61.2±6.5μm; day 30: CT: 75.3±18.1μm, AG: 77.7±15.7μm, AGPC: 84.9±13.6μm, 66.9±12.9μm). Sertoli cell (SOX9) numbers also increased while spermatogonia (PGP9) numbers per ST decreased (day 0: 6.94±0.31, day 30: CT: 1.84±0.64, AG: 2.65±0.88, AGPC: 3.47±0.7, MF: 2.11±0.84). Meiotic germ cells (SYCP3, CREM) were absent at day 0 and were generated starting day 5 (SYCP3) and 10 (CREM) in the different systems and maintained till day 30 (SYCP3 per ST; CT: 0.31±0.21, AG: 0.5±0.31, AGPC: 0.69±0.20, MF: 0.38±0.20 and CREM per ST: CT: 0.18±0.18, AG: 0.25±0.13, AGPC: 0.34±0.32, MF: 0.14±0.14). When compared to control (CT), significantly larger STs (days 10 to 30), a higher number of spermatogonia (PGP9) (day 30; AGPC: 3.72±0.70, CT: 1.84±0.64, p = 0.04), meiotic SYCP3 + (day 20, AGPC: 0.95±0.49, CT: 0.46±0.39, p = 0.01) and CREM+ cells (day 20, AGPC: 0.49±0.21, CT: 0.23±0.64, p = 0.02) were observed in the AGPC system. Apoptosis, lipid peroxidation (MDA), ST integrity, proliferating germ cells (Ki67/VASA), Leydig cells (INSL3) and testosterone levels were not significantly different between the different systems over the culture period.
Limitations, reasons for caution
The small sample size and inter-tissue variability could have limited the results of this study. Also it is not excluded that further differences, in terms of tissue growth, germ cell survival and differentiation, could be observed between the different systems if a more complex culture medium is used.
Wider implications of the findings
In contrast to rodents, modifying physical culture conditions minimally impacts the outcome of porcine ITT maturation ex-vivo. Due to anatomo-physiological similarities between pigs and humans, it is likely for similar results to be observed if applied to human ITT. Studies aiming at determining optimal culture medium components are rather needed.

Abstract
Introduction Many forms of mental disorders, especially psychotic disorders are characterized also by a worsening of sexual functioning. Sexual dysfunction has been shown to significantly correlate with a longer duration of untreated psychosis and with heavier psychotic symptomatology. Objectives The aim of this study is to validate the Italian version of the Arizona Sexual Experience (ASEX), a very handy and reliable tool to assess sexual dysfunction, in a population of people suffering from psychotic spectrum disorders. Methods Seventy-three psychiatric patients were recruited and assessed for mental illness and sexual functioning. We administered the Italian version of ASEX, adequately translated by two expert bilinguals. After 15 days we administered once again the test for test-retest reliability. Results Validation of ASEX revealed Cronbach’s coefficients >0.70 in both single items as in the total score. In addition, the test-retest reliability revealed Pearson’s coefficients >0.50 in the various domains. Confirmatory factor analysis revealed good fit indexes for the two factors model of ASEX (SRMR=0.54; CFI=0.974; RMSEA=0.135). Conclusions
This study represents the first validation in the Italian psychiatric context of a very useful specific tool for the sexual assessment in people suffering from mental illness. Our analysis revealed good psychometric characteristics in terms of confirmatory factor analysis, internal consistency, and test-retest reliability. Disclosure No significant relationships.

Abstract
Summary Background. The Italian Registry on Severe Asthma (IRSA) is the most recent and largestregistry in Italy. Objective. To improve the knowledge on the clinical and biological features of severe asthma (SA), and to monitor its treatments. Methods. To analyze clinical,functional, inflammatory, and treatment characteristics of severe asthmatics from the IRSA registry. Results. 851 subjects were enrolled. 31.8% and 64.5% of patients were submitted to oral corticosteroids (OCS), and monoclonal antibodies (MABs), respectively. At least tw ocomorbidities affected 77.4% patients. Asthma was uncontrolled in 62.2% patients. Uncontrolled patients had a higher frequency of exacerbations, and hospitalization, showing a highere osinophilic phenotype, a greater use of OCS, and being treated with MAB less frequently. However, uncontrolled patients treated with MAB had a lower use of OCS and a lower rateof hospitalization. Comparing SA patients with atopy and without atopy, the latter showeda greater use of OCS, and more frequent nasal polyposis and osteoporosis. Among SA patients with atopy treated with MAB, 36% were on a treatment targeting the IL-5 pathway. Conclusions and clinical relevance. This study shows the features of the greatest Italian registryof SA patients, revealing at the time of enrollment a poor disease control, and the use of OCSand MABs in about one third and two thirds of patients, respectively. SA is a complex diseasethat requires a more precise phenotyping and a greater disease control.

Abstract
Summary The number of patients with uncontrolled asthma is growing especially in young people. Although current therapies improve the disease management, the heterogeneity of clinical outcomes results in patients whose asthma is refractory to standard therapies. To understand not responsive phenotypes, we instituted a web-registry aimed to collect real life data of adolescent and adult patients. One-hundred and five Italian medical Centers are part of the network. Participants above 14 years and affected by severe asthma will be included in the study. Demographic and clinical data will be collected for 5 years on a dedicated electronic database. For the first time in Italy, our study will provide information on epidemiological, clinical and therapeutic aspects related to the natural course of the disease, filling the gap between adolescents and adults.

Abstract
COPD is a chronic pathological condition of the respiratory system characterized by persistent and partially reversible airflow obstruction, to which variably contribute remodeling of bronchi (chronic bronchitis), bronchioles (small airway disease) and lung parenchyma (pulmonary emphysema). COPD can cause important systemic effects and be associated with complications and comorbidities. The diagnosis of COPD is based on the presence of respiratory symptoms and/or a history of exposure to risk factors, and the demonstration of airflow obstruction by spirometry. GARD of WHO has defined COPD "a preventable and treatable disease". The integration among general practitioner, chest physician as well as other specialists, whenever required, assures the best management of the COPD person, when specific targets to be achieved are well defined in a diagnostic and therapeutic route, previously designed and shared with appropriateness. The first-line pharmacologic treatment of COPD is represented by inhaled long-acting bronchodilators. In symptomatic patients, with pre-bronchodilator FEV1 < 60%predicted and ≥ 2 exacerbations/year, ICS may be added to LABA. The use of fixed-dose, single-inhaler combination may improve the adherence to treatment. Long term oxygen therapy (LTOT) is indicated in stable patients, at rest while receiving the best possible treatment, and exhibiting a PaO2 ≤ 55 mmHg (SO2<88%) or PaO2 values between 56 and 59 mmHg (SO2 < 89%) associated with pulmonary arterial hypertension, cor pulmonale, or edema of the lower limbs or hematocrit > 55%. Respiratory rehabilitation is addressed to patients with chronic respiratory disease in all stages of severity who report symptoms and limitation of their daily activity. It must be integrated in an individual patient tailored treatment as it improves dyspnea, exercise performance, and quality of life. Acute exacerbation of COPD is a sudden worsening of usual symptoms in a person with COPD, over and beyond normal daily variability that requires treatment modification. The pharmacologic therapy can be applied at home and includes the administration of drugs used during the stable phase by increasing the dose or modifying the route, and adding, whenever required, drugs as antibiotics or systemic corticosteroids. In case of patients who because of COPD severity and/or of exacerbations do not respond promptly to treatment at home hospital admission should be considered. Patients with "severe or "very severe COPD who experience exacerbations should be carried out in respiratory unit, based on the severity of acute respiratory failure. An integrated system is required in the community in order to ensure adequate treatments also outside acute care hospital settings and rehabilitation centers. This article is being simultaneusly published in Multidisciplinary Respiratory Medicine 2014; 9:25.

Abstract
OBJECTIVES To evaluate the labeling accuracy of four myo-inositol products, designed for polycystic ovary syndrome (PCOS) treatment, available on the italian market and to perform a cost comparison based on myo-inositol content in milligrams for products analyzed. MATERIALS AND METHODS Four (4) myo-inositol products (3 sachet and 1 tablet formulations) were dissolved using water, and each sample was analyzed for myo-inositol content using a high-performance liquid chromatography (HPLC) method with index refraction detector. The amount of myo-inositol per purchased product was then divided into its purchase price in order to make cost comparisons between the products based on a 2 and 4 g/day dose. RESULTS A significant difference in the myo-inositol content, compared with the labeling was found for the products. Only 1 product contained more than 95% of the myo-inositol content claimed on the label, and there was a product with less than 75% of the labeling amount. Based on a 2-g myo-inositol per day dose, the cost of a 30-day supply ranged from Euro 20,77 and Euro 71,86, after correction by actual amount of myo-inositol. CONCLUSION There is a lack of conformity between declared and actual amount of myo-inositol among the products tested and the majority of the products contained less than 95% of labeled amounts. There should be a better control in the manufacturing process in order to ensure more quality and accuracy. Nowadays consumers cannot trust myo-inositol product labels to represent the product's content accurately or that product pricing is a reflection of myo-inositol content.

Abstract
BACKGROUND Patients with severe chronic airway obstruction might suffer dangerous hypoxemia after administration of a beta-agonist despite bronchodilation. METHODS We first compared the acute effects on gas exchange of two doses of formoterol Turbuhaler (9 and 18 microg) in 10 patients with acute exacerbation of COPD. Afterwards, we compared the acute effects of formoterol Turbuhaler 9 microug with those of formoterol/budesonide combination in a single inhaler (Turbuhaler) 9/320 microg in 10 other patients with acute exacerbation of COPD. Finally, we compared the changes in PaO(2) induced by formoterol Turbuhaler 9 microg or formoterol/budesonide combination in a single inhaler (Turbuhaler) 9/320 microg with those in FEV(1) in 10 other patients with acute exacerbation of COPD. Each agent was given on separate days, and the patients' arterial blood gases were measured at baseline and at intervals of 120 min. RESULTS Small but statistically significant declines in PaO(2) were found after administration of both formoterol 9 and 18 microg. In the second group of patients, formoterol 9 microg alone again induced a significant decrease in PaO(2). However, the simultaneous administration of budesonide 320 microg significantly reduced the acute effect of formoterol on PaO(2). In a third group of 10 patients we confirmed a small but significant decrease in PaO(2) after formoterol alone and the reduction of this effect when budesonide was administered simultaneously. Moreover, we also documented that addition of budesonide amplified the fast onset of action of formoterol. CONCLUSIONS These results suggest that when treating patients suffering from acute exacerbation of COPD with formoterol, it is prudent to check their arterial blood gases. In any case, combined administration of formoterol and budesonide reduces the potential for acute effects of formoterol on blood-gas tensions.
