Abstract
PURPOSE SARS-COV-2 is a pathogenic agent belonging to the coronavirus family, responsible for the current global world pandemic. Angiotensin-converting enzyme 2 (ACE-2) is the receptor for cellular entry of SARS-CoV-2. ACE-2 is a type I transmembrane metallo-carboxypeptidase involved in the Renin-Angiotensin pathway. By analyzing two independent databases, ACE-2 was identified in several human tissues including the thyroid. Although some cases of COVID-19-related subacute thyroiditis were recently described, direct proof for the expression of the ACE-2 mRNA in thyroid cells is still lacking. Aim of the present study was to investigate by RT-PCR whether the mRNA encoding for ACE-2 is present in human thyroid cells. METHODS RT-PCR was performed on in vitro ex vivo study on thyroid tissue samples (15 patients undergoing thyroidectomy for benign thyroid nodules) and primary thyroid cell cultures. RESULTS The ACE-2 mRNA was detected in all surgical thyroid tissue samples (n = 15). Compared with two reporter genes (GAPDH: 0.052 ± 0.0026 Cycles-1; β-actin: 0.044 ± 0.0025 Cycles-1; ACE-2: 0.035 ± 0.0024 Cycles-1), the mean level of transcript expression for ACE-2 mRNA was abundant. The expression of ACE-2 mRNA in follicular cells was confirmed by analyzing primary cultures of thyroid cells, which expressed the ACE-2 mRNA at levels similar to tissues. CONCLUSIONS The results of the present study demonstrate that the mRNA encoding for the ACE-2 receptor is expressed in thyroid follicular cells, making them a potential target for SARS-COV-2 entry. Future clinical studies in patients with COVID-19 will be required for increase our understanding of the thyroid repercussions of SARS-CoV-2 infection.

Abstract
To understand the influence of interchromophoric arrangements on photo-induced processes and optical properties of aggregates, it is fundamental to assess the contribution of local excitations [charge transfer (CT) and Frenkel (FE)] to exciton states. Here, we apply a general procedure to analyze the adiabatic exciton states derived from time-dependent density functional theory calculations, in terms of diabatic states chosen to coincide with local excitations within a restricted orbital space. In parallel, motivated by the need of cost-effective approaches to afford the study of larger aggregates, we propose to build a model Hamiltonian based on calculations carried out on dimers composing the aggregate. Both approaches are applied to study excitation energy profiles and CT character modulation induced by interchromophore rearrangements in perylene bisimide aggregates up to a tetramer. The dimer-based approach closely reproduces the results of full-aggregate calculations, and an analysis in terms of symmetry-adapted diabatic states discloses the effects of CT/FE interactions on the interchange of the H-/J-character for small longitudinal shifts of the chromophores.

Abstract
BACKGROUND Gestational diabetes mellitus (GDM) is a common pregnancy complication characterized by hyperglycaemia with onset or first recognition during pregnancy. Risk factors include family history of diabetes, previous GDM, genetic predisposition for GDM/type 2 diabetes, insulin resistance conditions such as overweight, obesity and ethnicity. Women with GDM are at high risk for fetal macrosomia, small for gestational age, neonatal hypoglycaemia, operative delivery and caesarean delivery. The aim of this narrative review is to summarize the most recent findings of diagnosis and treatment of GDM in order to underline the importance to promote adequate prevention of this disease, especially through lifestyle interventions such as diet and physical activity. METHODS The research was conducted using the following electronic databases, MEDLINE, EMBASE, Web of Science, Scopus, ClinicalTrial.gov, OVID and Cochrane Library, including all published randomized and non-randomized studies as well as narrative and systematic reviews. RESULTS The lack of universally accepted criteria makes the definition of diagnosis and prognosis of this condition difficult. Early diagnosis and glucose blood level control may improve maternal and fetal short and long-term outcomes. Treatment strategies include nutritional interventions and exercise. Medical treatment can be necessary if these strategies are not effective. Moreover, novel non-pharmacologic agents such as myo-inositol seem to be effective and safe both in the prevention and the treatment of GDM. CONCLUSIONS It is important to promote adequate prevention of GDM. Further studies are needed in order to better define the most appropriate strategies for the clinical management of women affected by GDM.

Abstract
OBJECTIVE To evaluate the ability of oral supplements with immune-stimulating molecules (Sambucus nigra, Zinc, Tyndallized Lactobacillus acidophilus (HA122), Arabinogalactans, vitamin D, vitamin E and vitamin C) to reduce the inflammation of the upper airway tract and improve the outcome of otitis media with effusion (OME) in children. PATIENTS AND METHODS Randomized controlled trial. One-hundred ninety-eight children (CI 95%: 12-96 months) were divided into four groups. Group 1 (48 subjects) received 10 ml of oral supplements (OS) with immune-stimulating molecules for three months (20 days consecutively, then 10 days of suspension - the therapeutic scheme was repeated three times); Group 2 (54 children) underwent treatment with 10 ml of OS for 90 consecutive days; Group 3 (48 subjects) received 15 ml of OS for 45 consecutive days; a control group (48 children) underwent the standard treatment for rhinitis and OME. Outcome measures included otoscopy, tympanometry, fibroendoscopy, and the pure tone audiometry (PTA) at T0 (before treatment), T1 (45 days after treatment), and T2 (90 days after treatment). RESULTS All children treated with OS showed a reduction of Upper Airway Infection (UAI) episodes and OME compared to the control group independent of the administration method and posology. The three groups treated with OS showed statistically significant differences between T0 and T2 for otoscopy, tympanometry, fibroendoscopy, and PTA. In Group 2, the otoscopy and the tympanometry scores improved at T1. Group 2 and 3 had better PTA results than Group 1. CONCLUSIONS OS with immune-stimulating molecules should be considered as a supporting therapy in children affected by recurrent episodes of UAI associated with OME due to their capacity to improve the immune response and reduce the inflammatory phenomena. OS can improve the fibroendoscopic findings by restoring middle ear ventilation, in addition to their ability to reduce inflammation in the middle ear.

Abstract
COVID-19 pandemic has underlined that unknown viral infections, which jump from animals to humans, can be extremely dangerous. In case of new viruses as SARS-CoV2, available drugs can fail to contrast the virus aggressiveness leading patients to death. Long time is necessary to create a vaccine, but immediate solutions are necessary to stop the mortality COVID-19 related. We have learned that the immune-system is the key to reduce the severity of COVID-19 and, through its modulation, it has been possible saving people's life. In this short communication, we discuss the use of nutraceuticals to modulate and stimulate the immune answer for reducing the severity of COVID-19 symptoms. The nutraceuticals are safe and can be administered to all ages. In addition, combination of natural anti-viral elements and immune-stimulating molecules already successfully tested against others upper-respiratory tract infections-could be efficient against SARS-CoV2. We believe that these natural molecules could really be a valid ally against COVID-19, especially in this moment in which a SARS-CoV2 vaccine is still not available.

Abstract
OBJECTIVE In the last decades, several cognitive-enhancing drugs have been sold onto the drug market. Methylphenidate and analogs represent a sub-class of these new psychoactive substances (NPS). We aimed to review the use and misuse of methylphenidate and analogs, and the risk associated. Moreover, we exhaustively reviewed the scientific data on the most recent methylphenidate analogs (methylphenidate and ethylphenidate excluded). MATERIALS AND METHODS Literature search was performed on methylphenidate and analogs, using specialized search engines accessing scientific databases. Additional reports were retrieved from international agencies, institutional websites, and drug user forums. RESULTS Methylphenidate/Ritalin has been used for decades to treat attention deficit disorders and narcolepsy. More recently, it has been used as a cognitive enhancer and a recreational drug. Acute intoxications and fatalities involving methylphenidate were reported. Methylphenidate was scheduled as an illegal drug in many countries, but NPS circumventing the ban and mimicking the psychostimulant effects of methylphenidate started being available: ethylphenidate, 3,4-dichloromethylphenidate, 3,4-dichloroethylphenidate, 4-fluoromethylphenidate, 4-fluoroethylphenidate, methylnaphthidate, ethylnaphthidate, isopropylphenidate, propylphenidate, 4-methylmethylphenidate, and N-benzylethylphenidate have been available in the past few years. Only little data is currently available for these substances. Many intoxications involving methylphenidate analogs were reported. To date, ethylphenidate was involved in 28 fatalities, although it was reportedly directly related to the cause of death in only 7 cases; 3,4-dichloroethylphenidate was involved in 1 death. CONCLUSIONS The rapid expansion of methylphenidate analogs onto the drug market in the past few years makes likely the occurrence of intoxications and fatalities in the next years. Careful monitoring and systematic control of methylphenidate analogs should be undertaken to reduce the uprising threat, and education efforts should be made among high-risk populations.

Abstract
This study aims to describe the native microbiota of fermented spelt, taking into consideration both lactic acid bacteria (LAB) and yeasts, for which little data are available. Five samples of commercial spelt flour were subjected to spontaneous fermentation to obtain a type I sourdough. A total of 186 LAB and 174 yeast isolates were selected at different refreshment steps and subjected to further analyses. Within LAB, coccal isolates constituted 78·5% of the total LAB, with the dominance of Pediococcus pentosaceus. Although documented before as a component, this is the first report of a spelt sourdough fermentation dominated by this homofermentative LAB, characterized by a high acidification rate, ability to utilize a wide range of carbon sources and to grow in high osmolarity conditions. Yeast communities resulted in four dominant species, Saccharomyces cerevisiae, Wickerhamomyces anomalus, Pichia fermentans and Clavispora lusitaniae. This study highlights for the first time the biodiversity and dynamics of yeast communities involved in sourdough fermentation of spelt. Compared to commercial baker's yeast, autochthonous W. anomalus, P. fermentans and S. cerevisiae isolates show a good performance, and their use could be an advantage for their acquired adaptation to the environment, providing stability to the fermentation process. SIGNIFICANCE AND IMPACT OF THE STUDY: Nowadays, there is a renewed interest in products based on spelt. This 'ancient grain' is a highly nutritional grain; however, its use is limited to bread-making processes, which are not standardized. The low baking and sensory quality of spelt can be overcome through fermentation processes. However, the autochthonous microbiota of spelt sourdough is poorly known. This study highlights the dynamics of microbial communities involved in sourdough fermentation of spelt and provides the basis for the selection of autochthonous cultures, with the aim of improving the nutritional potential of spelt and its rheology and bread-making properties.

Abstract
Obesity related to metabolic syndrome is gaining an increasing importance as the main risk factor for diseases and disability in the European region. We herein review the increasing trend of obesity and overweight in males and females from Europe, preventive programs addressed to children, youngsters, adult population and subjects with particular diseases which can profit from healthy nutrition. The main feature is that some European countries have implemented programs on World Health Organization (WHO) proposals, while some others have focused attention only on some aspects. Based on the reported obesity increase over the last twenty years, prevention programs seem to have been ineffective. Most likely, the effects will be observed later on. In this concern, it will be fundamental to continue and finance the countries of the European region, where those programs have been extensively applied, to obtain even better results in terms of obesity prevention.

Abstract
OBJECTIVE This study analyzed the appropriateness of drug therapies prescribed for a particular category of patients: the seafarers. We investigated an important problem of this area: the off-label use of drugs, which resulted to be a consequence of major shortcomings in the on-board pharmacies of ships. The off-label use of drugs is allowed, but can lead to some not negligible ethical and health problems, compromising the quality of provided healthcare. MATERIALS AND METHODS The analysis was performed on electronic health records of patients onboard ships without physicians, and assisted by the CIRM from 2011 to 2015. This work is divided into two phases: in the first one, we classified the diagnoses registered onboard on the basis of the ICD-10 classification proposed by the WHO. In the second phase, we evaluated the congruence of the pharmacological therapies prescribed by CIRM physicians, according to the MICROMEDEX Database, which provides comprehensive information about drugs and their use. RESULTS From the analysis emerged that prescribed drugs were not always corresponded to their primary indication of use. In particular, in 2011 off-label drug use was widely spread (more than 30%) in some ICD-10 classes. In the following years (2012-2015) a decrease of off-label use of drugs was noticed. CONCLUSIONS The results suggest that a standardization of onboard pharmacies is crucial, in order to have a complete on-board pharmacy that will allow preventing and counteracting any situation of health danger, which may occur onboard, ensuring high quality healthcare to seafarers all over the world.

Abstract
AIM To study Weissella cibaria and Weissella confusa strains, lactic acid bacteria (LAB) members naturally present in food products, but not yet included in Qualified Presumption of Safety (QPS) list of European Food Safety Authority (EFSA). METHODS AND RESULTS We carried out a comparative genome analysis of 23 sequenced W. cibaria and 7 W. confusa genomes, in parallel with a physiological and functional characterization of several strains previously isolated from sourdough-like maize bran fermentation. The genome analysis revealed the absence of dedicated pathogenicity factors. Some putative virulence genes found in Weissella genomes were also present in other LAB strains, considered safe by EFSA and commonly used as probiotics. The physiological tests carried out on our strains corroborated the genomic results. Moreover, the following functional traits of interest to application in the food sector were identified: the majority of tested strains displayed high acidification rate, high reducing ability, production of exopolysaccharides (EPS), arabinoxylan degradation ability, growth in the presence of fructo-oligosaccharides (FOS), bile and gastric juice tolerance, and antifungal activity. CONCLUSIONS These results provide evidence for the possible use of selected strains of W. cibaria and W. confusa in the food sector. SIGNIFICANCE AND IMPACT OF THE STUDY This polyphasic study adds to the body of knowledge on the functional and applicable characteristics of these controversial species of LAB. This knowledge contributes to design new selected cultures included in the QPS list required for food applications.

Abstract
PURPOSE To estimate the contribution of cryopreservation to the cumulative live birth rate (CLBR) after law modification in Italy in the era of vitrification and freeze-all. METHODS The Italian National Registry performed a cycle-based data collection. Nine Italian IVF clinics were involved incorporating a total of 10,260 fresh cycles performed between January 2015 and April 2016 resulting in 9273 oocyte retrievals and 3266 subsequent warming cycles from the same oocyte retrievals performed up to December 2016. Mean female age was 37 ± 4.3 years. Primary outcome measure was CLBR per oocyte retrieval. Confounding factors were tested in multivariate regression analysis, and the relative impact of cryopreservation to the CLBR in different patient categories was calculated. RESULTS CLBR per oocyte retrieval was 32.6%, 26.5%, 18.7%, 13.0%, and 5.5% for women younger than 36, aged 36-39, 40-41, and older than 41 years, respectively. The total relative contribution of oocyte/embryo cryopreservation was 40.6% (95% CI 38.41-42.75). An association between maternal age, number of oocytes retrieved, fertilization rate, cryopreservation, and cumulative live birth was shown. When adjusted for confounders, a 2.3-fold increase was observed in the chance of live birth when cryopreservation was performed (OR 2.3; 95% CI 1.99-2.56). In high responder patients (> 15 oocytes retrieved) where freeze-all was applied in 67.6% of cycles to avoid the risk of hyper stimulation syndrome, the relative contribution of vitrification to the CLBR was 80.6%. CONCLUSIONS Cryopreservation is essential in IVF and should always be available to patients to optimize success rates. Multicentric, cycle-based data analyses are crucial to provide infertile couples, clinicians, and regulatory bodies with accurate information on IVF effectiveness including fresh and cryopreserved cycles.

People with Duchenne muscular dystrophy (DMD), develop a respiratory muscle weakness that results in weakened cough, airway clearance impairment and over time respiratory failure and death. Assessment of cough effectiveness through vital capacity, peak cough flow and maximal inspiratory and expiratory pressures has been used to identify the optimal timing of cough augmentation techniques initiation. The choice of therapies depends on physician knowledge, and patient/care giver abilities. The purpose of this review is to clarify mechanisms of action, benefits and disadvantages of available techniques, such as manual cough-assisting manoeuvres, glossopharyngeal breathing, air stacking by resuscitator bag or by volume-cycle ventilator, and mechanical insufflator-exsufflator. Mechanisms of mucus mobilization, like intrapulmonary percussive ventilation, may have a therapeutic role in the case of persistent atelectasis. It is also crucial to recognize the initial phase of an acute respiratory exacerbation, increase the use of these techniques which may reduce morbidity and mortality.

Abstract
Procalcitonin (PCT), a precursor for calcitonin, is a prohormone involved in the inflammatory processes, which has been poorly studied in the context of pregnancy. During severe inflammation, PCT derives from almost all cell types, including monocytes and parenchymal tissues, making it a good predictive and diagnostic marker of an inflammatory state with rapidly increased serum levels in inflammation or sepsis. In normal pregnancy, PCT is basally expressed at very low level by decidual cells, even if decidual macrophages, which in normal pregnancy are skewed to M2 macrophages, are resistant to lipopolysaccharide (LPS)-induced production of PCT. As PCT increase is associated with an inflammatory state, several research groups investigated whether PCT can be considered a marker of pre-eclampsia, a pregnancy disease characterized by systemic inflammation. The first aim of this review is to summarize what is already known about the tissues synthesizing PCT, about the stimuli that cause the increase of circulating PCT levels and how PCT acts as a proinflammatory stimulus by itself. Secondly, we will describe the role of this prohormone in normal pregnancy and in pregnancies complicated by pre-eclampsia, highlighting the involvement of the decidual macrophages and the proinflammatory cytokine tumor necrosis factor-α in the modulation of PCT expression in the decidual microenvironment.

Abstract
AIM This paper aims to examine the legal status of the human embryo taking into consideration Article 1 of the Italian law on medically assisted procreation, which protects the human embryo, which is recognised as an individual holding the same rights as already born children. The progressive increase in legal decisions regarding reproductive technologies requires a re-examination of the traditional legal categories of "subjectivity" and legal capacity, and a deeper understanding of the status of the human embryo as a subject, or individua. MATERIALS AND METHODS The following sources were searched: Institutional websites, Research Centre for Social Investments reports, updated jurisprudence and Rulings of Italian Constitutional Court and European Court of Human Rights. In addition, also the following databases were searched: PubMed and Scopus, using the following keywords: medically assisted procreation (MAP) and embryo. RESULTS The authors believe that the best orientation is the modern principle of equality (non-discrimination); according to them, the need to protect unborn life requires therefore the consideration of interests which can no longer be confined to the solely patrimonial ones held by the embryo. The paper draws attention to a series of non-patrimonial interests, for whose protection the legal expert has to adopt innovative safeguarding techniques. In this context, there emerge some rights worthy of protection whose potential holders are as yet unborn.

Abstract
Performance enhancing drug use in sport arguably constitutes a crisis, and as such, targeted measures are needed in order to stem it. Substance abuse in professional sports and competitions has besmirched many world-class athletes' reputations and standing, in addition to jeopardizing their health. Furthermore, there are many instances of amateur athletes and school-aged competitors who have taken to using such substances as well, significantly exacerbating the overall picture. The widespread acknowledgement of the potentially life-threatening consequences of performance-enhancing drug use has prodded sports organizations and governments into cooperating on many different levels to preserve the ethical grounding and soundness of sport competitions; unlawful substance abuse is in fact liable to undermine the very core of fairness in competition. Doping, along with various forms of cheating, has been recorded throughout the history of sport: prohibition in itself is all but ineffective without reliable and systematic detection strategies and enforcement of sanctions.

Abstract
INTRODUCTION AND OBJECTIVES Atopic dermatitis (AD) is the most common cutaneous inflammatory disease in both adults and children. Although emerging therapeutic approaches are being investigated for the management of pediatric AD, it still needs to be managed with conventional treatments. This consensus document is aimed at providing an update on general management and therapies of pediatric AD, defining practical recommendations for using both topical and systemic agents. MATERIAL AND METHODS A panel of experts consisting of dermatologists and pediatricians were convened in order to define statements, through a Delphi process, standardizing the management of AD in pediatric subjects in a real-world setting. RESULTS A set of practical recommendations obtaining an at least 75% agreement was presented. CONCLUSIONS This set of practical recommendations represents a simple and fast snapshot on the pediatric use of common anti-AD therapeutics.
