Abstract
Two-dimensional (2D) organic-inorganic metal halide perovskites have gained immense attention as alternatives to three-dimensional (3D) perovskites in recent years. The hydrophobic spacers in the layered structure of 2D perovskites make them more moisture-resistant than 3D perovskites. Moreover, they exhibit unique anisotropic electrical transport properties due to a structural confinement effect. In this study, four lead-free Dion-Jacobson (DJ) Sn-based phase perovskite single crystals, 3AMPSnI4, 4AMPSnI4, 3AMPYSnI4, and 4AMPYSnI4 [AMP = (aminomethyl)-piperidinium, AMPY = (aminomethyl)pyridinium] are reported. Results reveal structural differences between them impacting the resulting optical properties. Namely, higher octahedron distortion results in a higher absorption edge. Density functional theory (DFT) is also performed to determine the trends in energy band diagrams, exciton binding energies, and formation energies due to structural differences among the four single crystals. Finally, a field-effect transistor (FET) based on 4AMPSnI4 is demonstrated with a respectable hole mobility of 0.57 cm2 V-1 s-1 requiring a low threshold voltage of only -2.5 V at a drain voltage of -40 V. To the best of our knowledge, this is the third DJ-phase perovskite FET reported to date.

Abstract
The relationship between COVID-19 and nasopharyngeal (NP) microbiota has been investigated mainly in the adult population. We explored the NP profile of children affected by COVID-19, compared to healthy controls (CTRLs). NP swabs of children with COVID-19, collected between March and September 2020, were investigated at the admission (T0), 72 h to 7 days (T1), and at the discharge (T2) of the patients. NP microbiota was analyzed by 16S rRNA targeted-metagenomics. Data from sequencing were investigated by QIIME 2.0 and PICRUSt 2. Multiple machine learning (ML) models were exploited to classify patients compared to CTRLs. The NP microbiota of COVID-19 patients (N = 71) was characterized by reduction of α-diversity compared to CTRLs (N = 59). The NP microbiota of COVID-19 cohort appeared significantly enriched in Streptococcus, Haemophilus, Staphylococcus, Veillonella, Enterococcus, Neisseria, Moraxella, Enterobacteriaceae, Gemella, Bacillus, and reduced in Faecalibacterium, Akkermansia, Blautia, Bifidobacterium, Ruminococcus, and Bacteroides, compared to CTRLs (FDR < 0.001). Exploiting ML models, Enterococcus, Pseudomonas, Streptococcus, Capnocytopagha, Tepidiphilus, Porphyromonas, Staphylococcus, and Veillonella resulted as NP microbiota biomarkers, in COVID-19 patients. No statistically significant differences were found comparing the NP microbiota profile of COVID-19 patients during the time-points or grouping patients on the basis of high, medium, and low viral load (VL). This evidence provides specific pathobiont signatures of the NP microbiota in pediatric COVID-19 patients, and the reduction of anaerobic protective commensals. Our data suggest that the NP microbiota may have a specific disease-related signature since infection onset without changes during disease progression, regardless of the SARS-CoV-2 VL. IMPORTANCE Since the beginning of pandemic, we know that children are less susceptible to severe COVID-19 disease. A potential role of the nasopharyngeal (NP) microbiota has been hypothesized but to date, most of the studies have been focused on adults. We studied the NP microbiota modifications in children affected by SARS-CoV-2 infection showing a specific NP microbiome profile, mainly composed by pathobionts and almost missing protective anaerobic commensals. Moreover, in our study, specific microbial signatures appear since the first days of infection independently from SARS-CoV-2 viral load.

Abstract
PURPOSE Calcitonin (Ct) is currently the most sensitive biochemical marker of C-cell disease (medullary thyroid cancer [MTC] and C-cell hyperplasia), but its specificity is relatively low. Our aim was to examine whether autoimmune atrophic gastritis (AAG) and chronic hypergastrinemia, with or without chronic autoimmune thyroiditis (AT), are conditions associated with increased Ct levels. METHODS Three groups of patients were consecutively enrolled in this multicentric study: group A consisted of patients with histologically-proven AAG (n = 13; 2 males, 11 females); group B fulfilled the criteria for group A but also had AT (n = 92; 15 males, 77 females); and group C included patients with AT and without AAG (n = 37; 6 males, 31 females). RESULTS Median Ct levels did not differ between the three groups. Ct levels were undetectable in: 8/13 cases (61.5%) in group A, 70/92 (76.1%) in group B, and 27/37 (73.0%) in group C. They were detectable but ≤ 10 ng/L in 4/13 (30.8%), 20/92 (21.7%) and 7/37 (18.9%) cases, respectively; and they were > 10 ng/L in 1/13 (7.7%), 2/92 (2.2%) and 3/37 (8.1%) cases, respectively (P = 0.5). Only three patients had high Ct levels (> 10 ng/L) and high gastrin levels and had an MTC. There was no correlation between Ct and gastrin levels (P = 0.353, r = 0.0785). CONCLUSIONS High gastrin levels in patients with AAG do not explain any hypercalcitoninemia, regardless of whether patients have AT or not. This makes it mandatory to complete the diagnostic process to rule out MTC in patients with high Ct levels and AAG.

Abstract
Neuronal ceroid lipofuscinosis (NCL) is an umbrella term referring to the most frequent childhood-onset neurodegenerative diseases, which are also the main cause of childhood dementia. Although the molecular mechanisms underlying the NCLs remain elusive, evidence is increasingly pointing to shared disease pathways and common clinical features across the disease forms. The characterization of pathological mechanisms, disease modifiers, and biomarkers might facilitate the development of treatment strategies.The DEM-AGING project aims to define molecular signatures in NCL and expedite biomarker discovery with a view to identifying novel targets for monitoring disease status and progression and accelerating clinical trial readiness in this field. In this study, we fused multiomic assessments in established NCL models with similar data on the more common late-onset neurodegenerative conditions in order to test the hypothesis of shared molecular fingerprints critical to the underlying pathological mechanisms. Our aim, ultimately, is to combine data analysis, cell models, and omic strategies in an effort to trace new routes to therapies that might readily be applied in the most common forms of dementia.

Abstract
The reversal of halide ions is studied under various conditions. However, the underlying mechanism of heat-induced reversal remains unclear. This work finds that dynamic disorder-induced localization of self-trapped polarons and thermal disorder-induced strain (TDIS) can be co-acting drivers of reverse segregation. Localization of polarons results in an order of magnitude decrease in excess carrier density (polaron population), causing a reduced impact of the light-induced strain (LIS - responsible for segregation) on the perovskite framework. Meanwhile, exposing the lattice to TDIS exceeding the LIS can eliminate the photoexcitation-induced strain gradient, as thermal fluctuations of the lattice can mask the LIS strain. Under continuous 0.1 W cm⁻2 illumination (upon segregation), the strain disorder is estimated to be 0.14%, while at 80 °C under dark conditions, the strain is 0.23%. However, in situ heating of the segregated film to 80 °C under continuous illumination (upon reversal) increases the total strain disorder to 0.25%, where TDIS is likely to have a dominant contribution. Therefore, the contribution of entropy to the system's free energy is likely to dominate, respectively. Various temperature-dependent in situ measurements and simulations further support the results. These findings highlight the importance of strain homogenization for designing stable perovskites under real-world operating conditions.

Abstract
Metal halide perovskite-based tandem solar cells are promising to achieve power conversion efficiency beyond the theoretical limit of their single-junction counterparts. However, overcoming the significant open-circuit voltage deficit present in wide-bandgap perovskite solar cells remains a major hurdle for realising efficient and stable perovskite tandem cells. Here, we report a holistic approach to overcoming challenges in 1.8 eV perovskites solar cells by engineering the perovskite crystallisation pathway by means of chloride additives. In conjunction with employing a self-assembled monolayer as the hole transport layer, we achieved an open-circuit voltage of 1.25 V and a power conversion efficiency of 17.0%. We elucidate the key role of methylammonium chloride addition in facilitating the growth of a chloride-rich intermediate phase that directs crystallisation of the desired cubic perovskite phase, and induce more effective halide homogenisation. The as-formed 1.8 eV perovskite demonstrates suppressed halide segregation and improved optoelectronic properties. This article is protected by copyright. All rights reserved.

Abstract
OBJECTIVE New methods for biofilm removal are being investigated. A recent new one involves the use of the electric field for biofilm removal. In particular, electrolytic cleaning works on the adhesion forces of the biofilm on the surfaces, with few studies showing promising results in decontamination and implant re-integration in the bone. This study aims at assessing the effect of a new decontamination device that implies the electric field for implant-biofilm removal. MATERIALS AND METHODS Three implants affected by peri-implantitis were selected for the study. After the treatment, the implants were observed by the Scanning Electron Microscopy. RESULTS All three samples showed no microbial biofilm in the application area, while the rest of the surface observed was covered with microbial biofilm, with an intensely thickened bacterial population. CONCLUSIONS Peri-mucositis and peri-implantitis prevention and early treatments are essential for implant maintenance, thus saving the surrounding hard and soft tissues. The technological innovation is providing electrolytic devices which act not only on the microbial population but on the biofilm adhesion to the implant surface, with promising results for a new and valid therapeutic option.

Abstract
SCOPE Dietary polyphenols can alter the gut microbiota (GM) and promote the production of bioactive metabolites. Several indoles result of GM metabolism of dietary tryptophan have been associated with intestinal barrier integrity. Our aim is to study the changes in GM-derived indoles during a polyphenol-rich (PR) diet intervention in older adults. METHODS AND RESULTS Randomized, controlled, crossover trial in adults ≥ 60 years living in a residential care facility during an 8-week PR versus control diet (n = 51). Seven GM-tryptophan metabolites are measured in serum, and metataxonomic analysis of GM is performed on fecal samples. Exploratory subgroup analyses are performed based on renal function (RF). The PR-diet significantly increases serum indole 3-propionic acid (IPA) in subjects with normal RF, but not in subjects with impaired RF. Other GM-tryptophan metabolites are not affected. Comparison of baseline GM composition shows shifts in Bacteroidales order members as well as higher abundance of Clostridiales in participants with normal RF. During the trial, variations of IPA are associated with changes in C-reactive protein (β = 0.32, p = 0.010) and GM, particularly with the Clostridiales (r = 0.35, p < 0.001) and Enterobacteriales (r = -0.15, p < 0.05) orders. CONCLUSION A PR diet increases the serum concentration of IPA in older adults with normal RF. Our findings may be important when defining appropriate dietary interventions for older adults.

Abstract
PURPOSE Accidental injury to the parathyroid glands (PTGs) is common during thyroid and parathyroid surgery. To overcome the limitation of naked eye in identifying the PTGs, intraoperative autofluorescence imaging has been embraced by an increasing number of surgeons. The aim of our study was to describe the technique and assess its utility in clinical practice. METHODS Near-infrared (NIR) autofluorescence imaging was carried out during open parathyroid and thyroid surgery in 25 patients (NIR group), while other 26 patients underwent traditional PTG detection based on naked eye alone (NO-NIR group). Primary variables assessed for correlation between traditional approach and autofluorescence were number of PTGs identified and incidence of postoperative hypoparathyroidism (hypoPT). RESULTS 81.9% of PTGs were detected by means of fluorescence imaging and 74.5% with visual inspection alone, with an average of 2.72 PTGs visualized per patient using NIR imaging versus approximately 2.4 per patient using naked eye (p = 0.38). Considering only the more complex total thyroidectomies (TTs), the difference was almost statistically significant (p = 0.06). Although not statistically significant, the observed postoperative hypoPT rate was lower in the NIR group. CONCLUSION Despite the limitations and technical aspects still to be investigated, fluorescence seems to reduce this complication rate by improving the intraoperative detection of the PTGs.

Abstract
Study question To date, no publications exist describing Blockchain in IVF (Hickman, 2020). Can Blockchain technology be used for traceability and accountability in IVF laboratory procedures? Summary answer Blockchain is an easy-to-implement technology for incorruptible traceability of a “Virus-Free” vitrification/warming procedure. What is known already In healthcare, Blockchain can become a tool to address challenges regarding sensitive data-sharing and traceability of medical and laboratory procedures. During the Covid-19 pandemic, many authors warned about the role of LN2 as a potential vector for virus contamination, and vitrification and warming were identified as critical procedures for risk of contamination for environments, surfaces, operators and cells. In this study we describe the first application of Blockchain in IVF for incorruptible traceability of a “Virus-Free” vitrification/warming procedure based on the combined use of UVC-Sterilized Liquid Nitrogen (LN2) and CE Medical Devices (CE-MD). Study design, size, duration Report on 2346 Ethereum Blockchain data transactions for IVF laboratory procedures mined from 01/10/2019 to 31/12/2021. The procedures were oocyte/embryo vitrification, warming or handling in LN2 after cryopreservation. For each vitrification, warming and handling a UVC-sterilized batch of LN2 was associated with the code assigned to the vitrification/warming procedure and with the lot number of the single-use sterile vitrification box (N-Sleeve). The clinical results obtained from warmed oocytes/embryos were observed as completion of this process. Participants/materials, setting, methods A Blockchain trusted “Virus-Free” vitrification/warming programme was set up using a specifically designed CE-MD N-Bath-System (Nterilizer-Italy). Each procedure was traced by the CE-MD’s software and a dedicated web application. Finally, data were made incorruptible by Ethereum Blockchain transactions. Before oocyte/embryo warming, vitrification carrier washing with UVC-sterilized LN2 was performed in accordance with Parmegiani et al (2012) and recent international anti-Covid guidelines. Main results and the role of chance Of the 2346 Blockchain transactions 1268 regarded vitrification and cryopreserved specimen handling procedures; 1078 transactions were frozen cell warmings (308 oocytes and 770 embryos) performed on 799 patients. To date, 445 pregnancies have been obtained (pregnancy rate: 41% per cycle; 56% per patient) and 219 babies have been born. Limitations, reasons for caution Ethereum is a decentralized, open-source blockchain with smart contract functionality. Ether is the native cryptocurrency which is highly susceptible to cost changes. Other public or private Blockchains may be used in future in healthcare with more stable transaction costs. Wider implications of the findings This is the first evidence of the application of Blockchain in IVF and many others will probably follow. Blockchain immutable records of LN2 sterilization combined with procedure codes and disposable lots represent incorruptible traces for “Virus-Free” vitrification/warming. During this pandemic 219 babies were born from cryopreservation procedures powered by Blockchain. Trial registration number Not Applicable

Abstract
BackgroundTemporal arteritis is the most common systemic vasculitis in patients aged >50 years, the most serious complications of which is visual loss. The arterial biopsy is the diagnostic gold standard; alongside the classic finding of transmural infiltrate and giant cells, other abnormalities have been described, of which it is not yet known whether they identify specific clinical subsets. PET is not yet used for diagnosis, but it can be suggestive in patients with high clinical suspect; it may be useful for assessing the extention of the disease in already diagnosed patients and for ruling out alternative diagnoses as infections and neoplasms. More recently, PET has been used to assess disease metabolic activityObjectivesThe aim of our study is to evaluate, in patients with histologically confirmed temporal arteritis, correlations between pathological subsets, metabolic activity and different clinical behavior.MethodsWe have recovered the medical records of patients with the diagnosis of temporal arteritis made in our Rheumatology service from January 2007 until now. We selected those satisfying the ACR 1990 criteria and, finally, those with a positive biopsy. We analyzed age at onset of symptoms, diagnostic delay, presence of PMR, fever, constitutional symptoms, headache, temporal artery induration, visual loss; we analyzed CRP, ESR, plasmatic Hb, PLT count, hypocomplementemia, ANA, aCL, ANCA. The referring pathologist, who didn’t know the history of patients, re-examined all the biopsies performed, focusing on: transmural, periadventitial, limited to small vessels or vasa vasorum infiltrate, presence of giant cells, macrophages, eosinophils, neutrophils, lymphocytes, plasmacells, stenosis, thrombosis, fibrinoid necrosis. The nuclear doctor retrieved the PET images by re-assigning each patient the relative PET VAS score. Descriptive analysis was performed: absolute and percentage frequencies were calculated for categorical variables and mean, standard deviation, range and percentiles for quantitative variables. The relationship between variables was tested by the chi-square test and the Mann-Whitney rank test. All analyzes were performed with the STATA software 14.2.ResultsWe analyzed 46 patients (F 32, M 14), average age at onset of symptoms of 75.5 yrs and average diagnostic delay of 3.2 months. Headache was reported by 37 patients, fever and asthenia by 26 and 24 respectively, jaw claudication and PMR by 18 and 7. 11 patients had visual loss while 4 and 2 respectively reported amaurosis and diplopia. Temporal artery induration was described in 24 patients. Tests of systemic inflammation were abnormal (mean CRP 85 mg/L, ESR 72.7 mm /1h); the finding of hypocomplementemia (1/26 patients), ANA, aCL and ANCA positivity (2/31, 1/27 and 1/25) was negligible. Histological analysis showed the prevalence of transmural infiltrate (100% of patients), giant cells (87%) and lymphocytes/macrophages (85% both); small vessel vasculitis (59%) and the presence of plasma cells (53%), neutrophils (48%) and eosinophils (22%) were less represented. Periadventitial infiltrate was described in 29% of patients, with negligibility of vasculitis limited to the adventitia and of the vasa vasorum (2 and 0/46). Intimal hyperplasia and necrosis (22 and 14/46) prevailed over calcifications, stenosis and thrombosis (7-5-1/46). PET was available in 14 patients including 6 positive (43%), with a median PET VAS score of 7 (range 6-21); 8/13 patients had not taken steroids prior to PET.ConclusionIn our retrospective study we observed, in addition to transmural infiltrate and giant cells, the presence of lymphocytes, macrophages and small vessel vasculitis. No correlation was observed between clinical findings, biological and metabolic activity, apart from the increased presence of giant cells in PET positive patients. Visual loss is slightly more common in PET negative patients. This may be due to severity of the cases which needed early steroid treatment.Disclosure of InterestsFrancesco Girelli: None declared, Silvia Asioli: None declared, Riccardo Galassi: None declared, Daniela Tirotta: None declared, Chiara Bellini: None declared, Simone Bernardi Paid instructor for: Paid instructor for Pharmaceuticals in 2013, Lucia Gardelli: None declared, Linda Petrini: None declared, Elisabetta Fabbri: None declared, Paolo Muratori: None declared

Abstract
BackgroundSystemic Sclerosis (SSc) is a complex autoimmune disease characterized by vascular damage, immune activation and fibrosis of skin and internal organs 1. Raynaud phenomenon (RP) is frequently the first symptom of the disease and growing evidences are supporting the hypothesis the SSc may be a vascular disease, with a pivotal role of endothelial cells, particularly in the very early phase2,3. Robust data support the use of vascular active drug to treat RP and to prevent vascular complication4–7.ObjectivesThe use of prostacyclin analog (PA) is evertything but standardized, with different regimen used all around the Country. We report data on the use of PA in a multicentric regional reality to understand which regimen are prevalent (and why) and if there is the opportunity to standardized them.MethodsWe collected data from an online survey exploring different items related to the use of PA.ResultsSurvey was fullfilled by 12 sites: 5 university hospital and 7 local hospitals, 7 driven by Rheumatologist and 5 from internal medicine specialists with/without concomitant rheumatologists. PA are ubiquitarly used for SSc-related digital ulcers (SSc-DU) and secondary RP but only a half of sites use it for primary RP. Seventy-five percent of sites (9/12) dispense PA at least once a month, but some other (1 each one respectively) on weekly basis, every other month or every 7 weeks. Drug administration may last from 2 to 5 consecutive days (mean 1.91+/- 1.5SD) with drug dose ranging from 0.5 to 2 ng/Kg/min with a minimum variability from site to site. Our regional hospitals may count on overall 68 spots, some available as beds (outpatient or inpatient), some as reclining chair or chair (outpatients only). University centers have usually more assigned personnel than local hospital (on average: 2 versus 1.5 physicians, 2 versus 1.2 nurse). Sites are able to offer meals (except one) and are able to accomodate from 1 to 12 patients at the same time (mean 3.45, +/- 3.2SD).ConclusionPA has known benefit in vascular involvement in SSc patients. Despite a multicenter palcebo-control study8 defining time and dose of this drugs and subsequent data based on the same regimen9, there is no homogeneity in treatment administration. The unequal treatment, based on our data, seems due to limited resources and personnel. High variability has been found in regimen duration and administration frequency.References[1]Ferri, C. et al.

Abstract
Surgical procedures in posterior area of maxillary might cause an oroantral communication and iatrogenic sinusitis. An undetected oroantral communication can cause the penetration of foreign bodies, such as dental impression materials, in the maxillary sinus, thereby contributing to persistent sinusitis. Given the occurrence of a very rare clinical and medicolegal case of persistent and drug-resistant sinusitis due to radiologically undetected fragments of silicone paste for dental impression in the maxillary antrum, a literature review was pursued through sensitive keywords in relevant databases for health sciences. All retrieved articles were considered and data about the kind of impression materials thrusted into the maxillary sinus, the diagnostic issues, the reported range of symptoms, and the occurrence of medicolegal issues were analyzed. The diagnosis resulted to be quite challenging and belatedly especially in case of healed oroantral communication and when the material retained in the maxillary sinus has similar radiodensity compared to the surrounding normal or inflammatory tissues. The case was then discussed in comparison with the reviewed literature for both clinical and medicolegal issues. Hints were provided to professionals to face the challenging diagnosis in similar rare cases and to avoid the possible related litigation.

Abstract
PURPOSE Aging can be characterized by increased systemic low-grade inflammation, altered gut microbiota composition, and increased intestinal permeability (IP). The intake of polyphenol-rich foods is proposed as a promising strategy to positively affect the gut microbiota-immune system-intestinal barrier (IB) axis. In this context, we tested the hypothesis that a PR-dietary intervention would affect the presence of bacterial factors in the bloodstream of older adults. METHODS We collected blood samples within a randomized, controlled, crossover intervention trial in which older volunteers (n = 51) received a polyphenol-enriched and a control diet. We quantified the presence of bacterial DNA in blood by qPCR targeting the 16S rRNA gene (16S; bacterial DNAemia). Blood DNA was taxonomically profiled via 16S sequencing. RESULTS Higher blood 16S levels were associated with higher BMI and markers of IP, inflammation, and dyslipidemia. PR-intervention did not significantly change bacterial DNAemia in the older population (P = 0.103). Nonetheless, the beneficial changes caused by the polyphenol-enriched diet were greatest in participants with higher bacterial DNAemia, specifically in markers related to IP, inflammation and dyslipidemia, and in fecal bacterial taxa. Finally, we found that the bacterial DNA detected in blood mostly belonged to γ-Proteobacteria, whose abundance significantly decreased after the polyphenol-rich diet in subjects with higher bacterial DNAemia at baseline. CONCLUSIONS This study shows that older subjects with higher bacterial DNAemia experienced a beneficial effect from a polyphenol-rich diet. Bacterial DNAemia may be a further relevant marker for the identification of target populations that could benefit more from a protective dietary treatment.

Abstract
BACKGROUND &AIM The MaPLE study was a randomized, controlled, crossover trial involving adults ≥60 y.o. (n = 51) living in a residential care facility during an 8-week polyphenol-rich (PR)-diet. Results from the MaPLE trial showed that the PR-diet reduced the intestinal permeability (IP) in older adults by inducing changes to gut microbiota (GM). The present work aimed at studying the changes in serum metabolome in the MaPLE trial, as a further necessary step to depict the complex crosstalk between dietary polyphenols, GM, and intestinal barrier. METHODS Serum metabolome was monitored using a semi-targeted UHPLC-MS/MS analysis. Metataxonomic analysis (16S rRNA gene profiling) of GM was performed on faecal samples. Clinical characteristics and serum levels of the IP marker zonulin were linked to GM and metabolomics data in a multi-omics network. RESULTS Compared to the control diet, the PR-diet increased serum metabolites related to polyphenols and methylxanthine intake. Theobromine and methylxanthines, derived from cocoa and/or green tea, were positively correlated with butyrate-producing bacteria (the order Clostridiales and the genera Roseburia, Butyricicoccus and Faecalibacterium) and inversely with zonulin. A direct correlation between polyphenol metabolites hydroxyphenylpropionic acid-sulfate, 2-methylpyrogallol-sulfate and catechol-sulfate with Butyricicoccus was also observed, while hydroxyphenylpropionic acid-sulfate and 2-methylpyrogallol-sulfate negatively correlated with Methanobrevibacter. The multi-omics network indicated that participant's age, baseline zonulin levels, and changes in Porphyromonadaceae abundance were the main factors driving the effects of a PR-diet on zonulin. CONCLUSION Overall, these results reveal the complex relationships among polyphenols consumption, intestinal permeability, and GM composition in older adults, and they may be important when setting personalized dietary interventions for older adults.

Abstract
Large magnetic optical rotary dispersion (Faraday rotation) has been demonstrated recently in methylammonium lead bromide. Here, we investigate the prospect of extending the active spectral range by altering the halogen. We also investigate the origins of large Faraday rotation in these diamagnetic materials using magnetic circular dichroism (MCD) spectroscopy and the Kramers-Kronig relations. We find that, while MAPbCl3 (MA = methylammonium) single crystals exhibit a large Verdet constant in the blue, no appreciable Faraday rotation is observed in the red/near infra-red for MAPbI3 single crystals. However, in all film samples, we find clear evidence of large MCD resulting from the Zeeman splitting of the highly resonant 1s exciton state. Our Kramers-Kronig calculations of Faraday rotation based on MCD data matches well with the dispersion of our experimental data for MAPbCl3 and MAPbBr3 , with some deviation in magnitude-demonstrating the excitonic nature of Faraday rotation in these materials. However, our calculations predict significant Faraday rotation in MAPbI3 , contrary to our experimental results, indicating a potential discrepancy between the properties of the thin film and single crystal.

Abstract
Background:Endocrine and metabolic imbalance conditions can affect the development of subjective abnormal perceptions within fibromyalgia (FMR). In the case of autoimmune thyroid disease (ATD), prolonged, clinically active states of impaired glandular function may be associated with an FMR-type condition. Less clear is the association between subclinical or rapidly well-controlled states of thyroid disease and the presence of FMR, since this assessment, although analysed in some previous studies, was usually performed on cohorts of subjects where the absence of any other confusing factors was not well defined.Objectives:To evaluate the prevalence of subclinical autoimmune thyroid disease, or functionally controlled autoimmune thyroid disease, in a retrospective cohort of consecutively diagnosed patients suffering from fibromyalgia condition.Methods:Over a 2 years period of time (2018-2019) a monocentric joint evaluation was activated with the endocrinology section of our healthcare area in order to consecutively monitor the subjects belonging to both specialist clinics. Patients with ATD were not unfrequently firstly evaluated in the rheumatology ambulatory. Diagnosis of FMR was defined according to the American College of Rheumatology 2010/2011 criteria. At the same time, at the rheumatology clinics, all cases addressed with diagnosis of fatigue or chronic pain of no defined origin were analysed in order to carefully identify any associated, comorbidity problems. The diagnosis of ATD was confirmed according to recognized international criteria. The following results will focus on subjects with chronic Hashimoto type Thyroiditis (HT).Results:Among the HT patients, 98% were women, aged between 28 and 64. Over the 2 years considered period of time, 65 subjects suffering from HT, showing no active disease or unstable endocrine function were addressed to the rheumatology clinics owing to FMR related symptoms. Among them, 55 (84.6%) had a confirmed diagnosis of FMR. Within this time, we recognized 239 consecutive diagnoses of FMR in subjects aging 22-76 years, with a number of 114 found to be devoid of factors (other than ATD) able to be responsible for chronic pain, except for a modest component of situational anxiety, or mild mood depression, not requiring any specific drug intervention. Among the 114, so called “primary” FMR, 35.6% showed to suffer from TCH, under confirmed clinical/hormonal remission, or in a preclinical, early stage of onset. Within the 125 subjects, carrying a FMR condition related to previous or associated fostering pathology, 26.8% were positive for current or previous thyroid problems. The prevalence of TCH, in the “secondary” FMR conditions differed significantly (p<0.01) from that of other FMR promoting diseases (eg connective tissue diseases, such as Sjogren Syndrome), except for moderate-severe mood disorders and/or anxiety, and the most severe chronic osteoarthritis conditions, showing a confirmed secondary neuropathy.Conclusion:Although limited in number, the here reported data confirm the hypothesis of a significant association between ATD and FMR, even in subjects who were considered to be in a subclinical condition or in full clinical remission by the endocrinology colleagues. The physiopathology of this association needs further appropriate insights.Acknowledgements:We thank Dr Alberto Petterle for his previous helpful contributionDisclosure of Interests:None declared

Abstract
The use of DNA damage as marker of oxidative stress, metabolic dysfunction and age-related diseases is debated. The present study aimed at assessing the level of DNA damage (evaluated as DNA strand-breaks, endogenous and oxidatively-induced DNA damage) in a group of older subjects with intestinal permeability enrolled within the MaPLE (Gut and Blood Microbiomics for Studying the Effect of a Polyphenol-Rich Dietary Pattern on Intestinal Permeability in the Elderly) intervention trial, to evaluate its association with clinical, metabolic and dietary markers. DNA damage in peripheral blood mononuclear cells was assessed by the comet assay in 49 older subjects participating in the study. Clinical and metabolic markers, markers of inflammation, vascular function and intestinal permeability were determined in serum. Food intake was estimated by weighted food diaries. On the whole, a trend towards higher levels of DNA damage was observed in men compared to women (p = 0.071). A positive association between DNA damage and clinical/metabolic markers (e.g., uric acid, lipid profile) and an inverse association with dietary markers (e.g., vitamin C, E, B6, folates) were found and differed based on sex. By considering the importance of DNA stability during aging, the results obtained on sex differences and the potential role of dietary and metabolic factors on DNA damage underline the need for further investigations in a larger group of older adults to confirm the associations found and to promote preventive strategies.

Abstract
For dental impression of a prepared tooth, the goal is a void-free negative representation from which an accurate cast of a tooth and its surrounding tissue can be reproduced. This in-vitro study assessed and compared the reproduction accuracies of surface detail obtained with three different dental elastomeric impression materials: vinyl polysiloxane (VPS), vinyl polyether silicone (VPES), and polyether (PE). A stainless-steel model with two abutments was used, with impressions taken 10 times for each material, for 20 abutment impressions per group, using a two-phase, one-step technique (heavy body/light body). The impressions were removed and assessed for numbers of enclosed voids and open voids visible on the surface. The defect frequency was 95% for impressions with the VPS and VPES materials, and 30% for the PE material. No significant differences were seen for number of impressions with defects for VPS versus VPES. Significant differences were seen for VPS and VPES versus the PE material (P <.05). No significant differences were seen for the defect type distributions across these three impression materials. The PE impression material showed better accuracy for reproduction of surface detail of these dental impressions compared to the VPS and VPES impression materials.

Abstract
Bandgap instability due to light-induced phase segregation in mixed-halide perovskites presents a major challenge for their future commercial use. Here we demonstrate that photoinduced halide-ion segregation can be completely reversed at sufficiently high illumination intensities, enabling control of the optical bandgap of a mixed-halide perovskite single crystal by optimizing the input photogenerated carrier density. We develop a polaron-based two-dimensional lattice model that rationalizes the experimentally observed phenomena by assuming that the driving force for photoinduced halide segregation is dependent on carrier-induced strain gradients that vanish at high carrier densities. Using illumination sources with different excitation intensities, we demonstrate write-read-erase experiments showing that it is possible to store information in the form of latent images over several minutes. The ability to control the local halide-ion composition with light intensity opens opportunities for the use of mixed-halide perovskites in concentrator and tandem solar cells, as well as in high-power light-emissive devices and optical memory applications.

Abstract
BACKGROUND & AIM Increased intestinal permeability (IP) can occur in older people and contribute to the activation of the immune system and inflammation. Dietary interventions may represent a potential strategy to reduce IP. In this regard, specific food bioactives such as polyphenols have been proposed as potential IP modulator due to their ability to affect several critical targets and pathways that control IP. The trial aimed to test the hypothesis that a polyphenol-rich dietary pattern can decrease serum zonulin levels, an IP surrogate marker involved in tight junction modulation, and can beneficially alter the intestinal microbiota, and IP-associated biochemical and clinical markers in older subjects. METHODS A randomised, controlled, cross-over intervention trial was performed. Sixty-six subjects (aged ≥ 60 y) with increased IP based on serum zonulin levels, were randomly allocated to one of the two arms of the intervention consisting of a control diet (C-diet) vs. a polyphenol-rich diet (PR-diet). Each intervention was 8-week long and separated by an 8-week wash out period. At the beginning and at the end of each intervention period, serum samples were collected for the quantification of zonulin and other biological markers. Faecal samples were also collected to investigate the intestinal microbial ecosystem. In addition, anthropometrical/physical/biochemical parameters and food intake were evaluated. RESULTS Fifty-one subjects successfully completed the intervention and a high compliance to the dietary protocols was demonstrated. Overall, polyphenol intake significantly increased from a mean of 812 mg/day in the C diet to 1391 mg/day in the PR-diet. Two-way analysis of variance showed a significant effect of treatment (p = 0.008) and treatment × time interaction (p = 0.025) on serum zonulin levels, which decreased after the 8-week PR-diet. In addition, a treatment × time interaction was observed showing a reduction of diastolic blood pressure (p = 0.028) following the PR-diet, which was strongest in those not using antihypertensive drugs. A decrease in both diastolic (p = 0.043) and systolic blood pressure (p = 0.042) was observed in women. Interestingly, a significant increase in fibre-fermenting and butyrate-producing bacteria such as the family Ruminococcaceae and members of the genus Faecalibacterium was observed following the PR intervention. The efficacy of this dietary intervention was greater in subjects with higher serum zonulin at baseline, who showed more pronounced alterations in the markers under study. Furthermore, zonulin reduction was also stronger among subjects with higher body mass index and with insulin resistance at baseline, thus demonstrating the close interplay between IP and metabolic features. CONCLUSIONS These data show, for the first time, that a PR-diet can reduce serum zonulin levels, an indirect marker of IP. In addition, PR-diet reduced blood pressure and increased fibre-fermenting and butyrate-producing bacteria. These findings may represent an initial breakthrough for further intervention studies evaluating possible dietary treatments for the management of IP, inflammation and gut function in different target populations.

Abstract
Polyphenols have great potential in regulating intestinal health and ameliorating pathological conditions related to increased intestinal permeability (IP). However, the efficacy of dietary interventions with these phytochemicals may significantly be influenced by interindividual variability factors affecting their bioavailability and consequent biological activity. In the present study, urine samples collected from older subjects undergoing a crossover intervention trial with polyphenol-rich foods were subjected to metabolomics analysis for investigating the impact of increased IP on the bioavailability of polyphenols. Interestingly, urinary levels of phase II and microbiota-derived metabolites were significantly different between subjects with healthier intestinal barrier integrity and those with increased IP disruption. Our results support that this IP-dependent impaired bioavailability of polyphenols could be attributed to disturbances in the gut microbial metabolism and phase II methylation processes. Furthermore, we also observed that microbiota-derived metabolites could be largely responsible for the biological activity elicited by dietary polyphenols against age-related disrupted IP.

Abstract
The evaluation of food intake in older subjects is crucial in order to be able to verify adherence to nutritional recommendations. In this context, estimation of the intake of specific dietary bioactives, such as polyphenols, although particularly challenging, is necessary to plan possible intervention strategies to increase their intake. The aims of the present study were to: (i) evaluate the nutritional composition of dietary menus provided in a residential care setting; (ii) estimate the actual intake of nutrients and polyphenols in a group of older subjects participating in the MaPLE study; and (iii) investigate the impact of an eight-week polyphenol-rich dietary pattern, compared to an eight-week control diet, on overall nutrient and polyphenol intake in older participants. The menus served to the participants provided ~770 mg per day of total polyphenols on average with small variations between seasons. The analysis of real consumption, measured using weighed food diaries, demonstrated a lower nutrient (~20%) and polyphenol intake (~15%) compared to that provided by the menus. The feasibility of dietary patterns that enable an increase in polyphenol intake with putative health benefits for age-related conditions is discussed, with a perspective to developing dietary guidelines for this target population.

Abstract
While growth and dissolution of surface nanobubbles have been widely studied in recent years, their stability under pressure changes or a temperature increase has not received the same level of scrutiny. Here, we present theoretical predictions based on classical theory for pressure and temperature thresholds (pc and Tc) at which unstable growth occurs for the case of air nanobubbles on a solid surface in water. We show that bubbles subjected to pinning have much lower pc and higher Tc compared to both unpinned and bulk bubbles of similar size, indicating that pinned bubbles can withstand a larger tensile stress (negative pressure) and higher temperatures. The values of pc and Tc obtained from many-body dissipative particle dynamics simulations of quasi-two-dimensional (quasi-2D) surface nanobubbles are consistent with the theoretical predictions, provided that the lateral expansion during growth is taken into account. This suggests that the modified classical thermodynamic description is valid for pinned bubbles as small as several nanometers. While some discrepancies still exist between our theoretical results and previous experiments, further experimental data are needed before a comprehensive understanding of the stability of surface nanobubbles can be achieved.

Abstract
Lead halide perovskites (LHPs) have become a promising alternative for a wide range of optoelectronic devices, thanks to their solution-processability and impressive optical and electrical properties. More recently, LHPs have been investigated in magneto-optic studies and have exhibited spin-polarized emission, photoinduced magnetization, and long spin lifetimes. Here, the viability of methylammonium lead bromide (MAPbBr3) single crystals as solution-processed Faraday rotators is demonstrated. Compared to terbium gallium garnet, the industry standard in the visible, it is found that MAPbBr3 exhibits Verdet constants (i.e., strength of Faraday effect) of similar or greater magnitude (up to 2.5x higher), with lower temperature dependence. Due to its low trap absorption, it is calculated that an optical isolator made from MAPbBr3, with appropriate antireflection coatings, should reach ≈95% transmission and achieve 40 dB isolation for incoming powers of over 2 W. It is also shown that the Verdet constant of MAPbBr3 can be calculated accurately from its dispersion in refractive index, allowing the possibility to predict similar effects in other perovskite materials.

Abstract
Background During aging, alterations of the intestinal microbial ecosystem can occur contributing to immunosenescence, inflamm-aging and impairment of intestinal barrier function (increased intestinal permeability; IP). In the context of a diet-microbiota-IP axis in older subjects, food bioactives such as polyphenols may play a beneficial modulatory role. Methods MaPLE is a project centered on a randomized, controlled cross-over dietary intervention trial [polyphenol-rich diet (PR-diet) versus control diet (C-diet)] targeted to older people (≥ 60 y) living in a well-controlled setting (i.e. nursing home). The 8-week interventions are separated by an 8-week wash-out period. Three small portions per day of selected polyphenol-rich foods are consumed during intervention in substitution of other comparable products within the C-diet. Biological samples are collected before and after each treatment period to evaluate markers related to IP, inflammation, vascular function, oxidative stress, gut and blood microbiomics, metabolomics. A sample size of 50 subjects was defined based on IP as primary outcome. Discussion Evidence that increasing the consumption of polyphenol-rich food products can positively affect intestinal microbial ecosystem resulting in reduced IP and decreased translocation of inflammogenic bacterial factors into the bloodstream will be provided. The integration of data from gut and blood microbiomics, metabolomics and other IP-related markers will improve the understanding of the beneficial effect of the intervention in the context of polyphenols−microbiota−IP interactions. Finally, findings obtained will provide a proof of concept of the reliability of the dietary intervention, also contributing to future implementations of dietary guidelines directed to IP management in the older and other at risk subjects. Trial registration The trial is registered at (ISRCTN10214981); April 28, 2017.

Abstract
The gut microbiota is involved in the regulation of the intestinal permeability (IP), whose disruption is a frequent condition in older people and is associated with the development of several diseases. The diet can affect the gut microbiota and IP, although the molecular mechanisms involved are unclear. Metabolomics is one of the suitable approaches to study the effects of diet on gut microbiota and IP, although, up to now, the research has focused only on a few dietary components. The aim here was to review the most recent literature concerning the application of metabolomics to the study of the diet-induced alterations of gut microbiota and the effects on IP, with a particular focus on the molecular pathways involved. An additional aim was to give a perspective on the future research involving dietary polyphenols, because despite their potential use in the management of increased IP, few studies have been reported to date.

Abstract
Increasing evidence links intestinal permeability (IP), a feature of the intestinal barrier, to several pathological or dysfunctional conditions. Several host and environmental factors, including dietary factors, can affect the maintenance of normal IP. In this regard, food bioactives, such as polyphenols, have been proposed as potential IP modulators, even if the mechanisms involved are not yet fully elucidated. The aim of the present paper is to provide a short overview of the main evidence from in vitro and in vivo studies supporting the role of polyphenols in modulating IP and briefly discuss future perspectives in this research area.

Abstract
In this work, we compare the existing nonpolarizable force fields developed to study the solid or solution phases of hybrid organic-inorganic halide perovskites with the AMOEBA polarizable force field. The aim is to test whether more computationally expensive polarizable force fields like AMOEBA offer better transferability between solution and solid phases, with the ultimate goal being the study of crystal nucleation, growth, and other interfacial phenomena involving these ionic compounds. In the context of hybrid perovskites, AMOEBA force field parameters already exist for several elements in solution, and we decided to leave them unchanged and to only parameterize the missing ones (Pb2+ and CH3NH3 + ions) in order to maximize transferability and avoid overfitting to the specific examples studied here. Overall, we find that AMOEBA yields accurate hydration free energies (within 5%) for typical ionic species while showing the correct ordering of stability for the different crystal polymorphs of CsPbI3 and CH3NH3PbI3. Although the existing parameters do not accurately reproduce all transition temperatures and lattice parameters, AMOEBA offers better transferability between solution and solid states than existing nonpolarizable force fields.

Abstract
PURPOSE Aim of the study was to assess the impact of the Italian Society of Anatomic Pathology and Diagnostic Cytology (SIAPEC) classification of 2014, on the treatment of indeterminate thyroid lesions (TIR3). METHODS We retrospectively analyzed patients undergoing thyroid surgery for TIR3 lesions between 2013 and 2018, at the General Surgery Department of Trieste University Hospital. According to the SIAPEC classification, patients were divided into TIR3A and TIR3B groups. All patients treated before 2014 underwent surgical treatment, and surgical specimens were retrospectively classified after revision of fine-needle aspiration cytology. Starting 2014, TIR3A patients were treated only when symptomatic (i.e., coexistent bilateral thyroid goiter or growing TIR3A nodules), whereas TIR3B patients always received surgical treatment. Hemithyroidectomy (HT) was the procedure of choice. Total thyroidectomy (TT) was performed in case of concurrent bilateral goiter, autoimmune thyroid disease, and/or presence of BRAF and/or RAS mutation. Lastly, we analyzed the malignancy rate in the two groups. RESULTS 29 TIR3A and 90 TIR3B patients were included in the study. HT was performed in 10 TIR3A patients and 37 TIR3B patients, respectively, with need for reoperation in 4 TIR3B (10.8%) patients due to histological findings of follicular thyroid carcinoma >1 cm. The malignancy rates were 17.2% in TIR3A and 31.1% in TIR3B, (p = 0.16). Predictability of malignancy was almost 89% in BRAF mutation and just 47% in RAS mutation. CONCLUSIONS The new SIAPEC classification in association with biomolecular markers has improved diagnostic accuracy, patient selection, and clinical management of TIR3 lesions.

Abstract
In guided bone regeneration (GBR) interventions, the incorrect manipulation of the soft tissues may lead to exposure of graft due to insufficient amount of tissue needed for a free-tension flap closure. The aim of this investigation was to evaluate the clinical and radiographical effectiveness of soft tissue augmentation in aesthetic areas. A total of 6 patients were treated in the Department of Medical, Oral and Biotechnological Sciences, University "G. D'Annunzio" of Chieti-Pescara, with a radiographical follow-up at 1 year from the loading. At the follow up, no soft tissue dehiscence was observed This study presented an innovative approach for soft tissue augmentation prior to bone regeneration in aesthetic areas. Augmentation of soft tissue with a silicon expander device before bone regeneration is a simple technique and also allows to obtain greater bone tissue in selective cases.

Abstract
Growing evidence support association between polyphenol intake and reduced risk for chronic diseases, even if there is a broad debate about the effective amount of polyphenols able to exert such protective effect. The present systematic review provides an overview of the last 10-year literature on the evaluation of polyphenol intake and its association with specific disease markers and/or endpoints. An estimation of the mean total polyphenol intake has been performed despite the large heterogeneity of data reviewed. In addition, the contribution of dietary sources was considered, suggesting tea, coffee, red wine, fruit and vegetables as the main products providing polyphenols. Total flavonoids and specific subclasses, but not total polyphenols, have been apparently associated with a low risk of diabetes, cardiovascular events and all-cause mortality. However, large variability in terms of methods for the evaluation and quantification of polyphenol intake, markers and endpoints considered, makes it still difficult to establish an evidence-based reference intake for the whole class and subclass of compounds. Nevertheless, the critical mass of data available seem to strongly suggest the protective effect of a polyphenol-rich dietary pattern even if further well targeted and methodologically sound research should be encouraged in order to define specific recommendations.

Abstract
INTRODUCTION In people with haemophilia (PWH) with severe arthropathy, total joint replacement (TJR) can be undertaken if conservative management fails. Post-operative rehabilitation treatment is an important part of the comprehensive management of patients undergoing TJR. AIM To compare post-operative standard rehabilitation (SR) and SR plus water rehabilitation (WR) in PWH undergoing TJR. METHODS PWH who were admitted to our centre between June 2003 and December 2016 for rehabilitation after TJR were included in the study. Rehabilitation included SR (ie, manual and mechanical mobilization, scar tissue massage, light muscle strengthening exercises and walking training with and without crutches) with or without WR. WR exercises with floats of different size and volume were performed when possible. Range of motion (ROM), muscle strength, pain level, perceived health status and length of hospital stay were analysed retrospectively. RESULTS A total of 184 patients (233 rehabilitation programmes were enrolled in the study, corresponding to 160 after total knee replacement [TKR], 37 after total ankle replacement [TAR] and 36 after total hip replacement [THR]). Fifty-eight (25%) patients were treated with WR in addition to SR (32 for TKR, 19 for TAR and 7 for THR) with an average of 5.7 hours of WR. Muscle strength, pain and perceived health status improved significantly after rehabilitation. CONCLUSION This non-randomized study seems to indicate that WR plus SR improves muscle strength, pain and perceived health status more than SR alone in PWH undergoing TJR. It would be necessary, however, to carry out randomized comparative studies to confirm these provisional conclusions.

Abstract
OBJECTIVES Vertical transmission of HIV can be effectively controlled through antenatal screening, antiretroviral treatment and the services provided during and after childbirth for mother and newborn. In Italy, the National Health Service guarantees universal access to prenatal care for all women, including women with HIV infection. Despite this, children are diagnosed with HIV infection every year. The aim of the study was to identify missed opportunities for prevention of mother-to-child transmission of HIV. METHODS The Italian Register for HIV Infection in Children, which was started in 1985 and involves 106 hospitals throughout the country, collects data on all new cases of HIV infection in children. For this analysis, we reviewed the database for the period 2005 to 2015. RESULTS We found 79 HIV-1-infected children newly diagnosed after birth in Italy. Thirty-two of the mothers were Italian. During the pregnancy, only 15 of 19 women with a known HIV diagnosis were treated with antiretroviral treatment, while, of 34 women who had received an HIV diagnosis before labour began, only 23 delivered by caesarean section and 17 received intrapartum prophylaxis. In 25 mothers, HIV infection was diagnosed during pregnancy or in the peripartum period. Thirty-one newborns received antiretroviral prophylaxis and 39 received infant formula. CONCLUSIONS We found an unacceptable number of missed opportunities to prevent mother-to-child transmission (MCTC). Eliminating HIV MTCT is a universal World Health Organization goal. Elucidating organization failures in Italy over the past decade should help to improve early diagnosis and to reach the zero transmission target in newborns.

Abstract
Lemierre's syndrome is also known as the forgotten disease, and is a rare but life-threatening complication that can arise after surgical extractions of infected mandibular third molars. Owing to its rarity, oral and maxillofacial surgeons might not immediately recognise or can underestimate the pathological signs, and consequently do not apply the appropriate therapy to treat the syndrome. Here, we report on the occurrence and management of a case of Lemierre's syndrome, where the complications affected the right sigmoid sinus. Since the condition appear to be underreported and not properly highlighted, eventual systematic review and meta-analysis of the occurrence of the Lemierre's syndrome are highly recommended.

Abstract
Purpose To study the efficacy and efficiency of a “universal warming protocol” for vitrified human embryos, based on subsequent steps with 1 and 0.5 M concentration of extracellular cryoprotectant (ECCP). Method Two studies on patients undergoing fertility treatments via ICSI: a prospective randomized controlled trial (RCT) and a retrospective cohort study (CS). Setting: Private assisted reproductive (AR) center. RCT: duration 01/03/2017–01/10/2017; 315 embryos at blastocyst stage obtained from 169 patients. Each patient’s embryos were first randomized for vitrification with two different kits: Vitrification Kit (Kitazato, Japan) and Sage Vitrification Kit (Origio, Denmark). The embryos were randomly warmed with either Kitazato (K) or Sage (S) warming kits, specifically: group A (KK), group B (KS), group C (SK), and group D (SS). Primary outcome measure: survival rate (number of embryos surviving per number of embryos warmed). Secondary: implantation rate (number of embryos implanted per number of embryos transferred). CS: duration 01/01/2013–31/12/2015 embryos from patients’ own oocytes; 10/04/2015–31/07/2017 embryos from donors’ oocytes. A total of 1055 embryos vitrified at cleavage stage obtained from 631 warming cycles: 847 of these obtained from patients’ own oocytes, 208 egg-donation-derived embryos. Each patient’s embryos were vitrified and warmed in various combinations of three different vitrification/warming kits: Kitazato (K), Sage (S), or made in-house in our laboratory (H). Vitrification/warming kits from different manufacturers are routinely used in our AR center, and the warming procedures are randomly performed with any available kit on a “first-in-first-out” basis, irrespective of the kit used for vitrification. Group names: KK, KS, SK, SS, SH, HK, HS, HH (embryos from patients’ own oocytes); eKK, eKS, eSK, eSS (egg-donation-derived embryos). Results Cryo-survival rates were comparable in all study groups. RCT. Group A 99.0% (96/97), group B 98.8% (83/84), group C 98.4% (61/62), and group D 98.6% (71/72). CS. Embryos from patients’ own oocytes: KK 96.4% (54/56), KS 100.0% (13/13), SK 98.8% (80/81), SS 97.2% (174/179), SH 97.6% (40/41), HK 95.2% (20/21), HS 99.5% (187/188), and HH 97.4% (261/268). Egg-donation-derived embryos: eKK 100.0% (91/91), eKS 98.4% (60/61), eSK 100.0% (26/26), and eSS 96.7 (29/30). Implantation was generally comparable in all study groups—exceptions were in CS: KS vs. SK (P = 0.049), SS (P = 0.012), HS (P = 0.010), HH (P = 0.025); and SH vs. SS (P = 0.042), HS (P = 0.035). Conclusion Worldwide, millions of embryos have been cryopreserved using different vitrification kits; these studies establish that it is possible to combine different kits for vitrification and warming using a universal warming protocol. This can optimize costs, simplify lab routines, and favor embryo exchange between IVF centers. RCT registration number ISRCTN12342851.

Abstract
PURPOSE Bisphosphonate drug therapy provides benefits in the case of osteoporosis and carcinomas metastasizing to the bones, but it exposes patients to important side effects. The aim of this study was to investigate the incidence and the appropriate surgical treatment of bone lesions and fractures due to antiresorptive drug-related osteonecrosis of the jaws (ARONJ). METHODS Patients presenting with osteonecrosis lesions of the jaw, who were referred to the Maxillo-Facial unit of the University of L'Aquila, were considered for inclusion. Grade of the lesion and treatment choice was recorded for each patient. Descriptive statistics were calculated and the data were analysed with Chi-squared tests. A representative case of a fracture reduction with a supra-periostal approach is reported. RESULTS Among the 165 patients with ARONJ lesions, 112 were female and 53 were male. In total, 115 patients received intra-venous bisphosphonate therapy and 50 received oral bisphosphonate therapy. Five stage 2 lesions, three stage 2 lesions and two stage 3 lesions were not a consequence of dental procedures. Eighteen surgical bone excisions were performed and four pathological fractures were reduced. In one case (the reported one), the combined use of platelet-rich plasma and the supra-periostal approach leads to a successful 1-year follow-up. CONCLUSIONS ARONJ lesions are a type of pathological bone disease affecting the jawbones. The pathology pathway remains a controversial and frequently discussed topic. A surgically conservative strategy seems to be the best way to assure a comfortable quality of life to those patients negatively affected by this condition.

Abstract
AIM Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy. Despite its extremely favorable prognosis, cervical lymph node metastases are a common feature of PTC and a known independent risk factor for local recurrence. However, the role of prophylactic central neck dissection (PCND) remains a matter of debate in patients with clinically node-negative (cN0) PTC. To better clarify the current role of PCND in the surgical treatment of PTC, evaluating advantages and disadvantages of PCND and outcome of cN0 PTC patients who have been treated with either total thyroidectomy alone or in combination with PCND. A review of recent literature data is performed. METHODS Between January 2000 and December 2015, 186 consecutive patients with cN0 PTC were identified to be included in the present study. 74 of these underwent total thyroidectomy associated with PCND, while 112 patients underwent total thyroidectomy alone. The epidemiological and clinical-pathological data of all patients included were collected at diagnosis and during follow-up. RESULTS Overall complication rate was significantly higher in the group of patients undergoing PCND (39.2% vs. 17.8%, p = 0.0006). To be specific, they presented a considerably increased risk of temporary recurrent laryngeal nerve injury (p = 0.009) and of permanent hypothyroidism (p = 0.016). Overall survival and recurrence rates did not differ between those undergoing PCND and those undergoing total thyroidectomy alone (p = 1.000 and p = 0.715, respectively). CONCLUSIONS The results of the present study do not support the routine use of PCND in the treatment of cN0 PTC patients.
