Abstract
Developmental encephalopathies (DE), epileptic encephalopathies (EE) and developmental and epileptic encephalopathies (DEE) are overlapping neurodevelopmental disorders characterized by early-onset, often severe epileptic seizures, developmental delay, or regression and have multiple etiologies. Classical nosology in child neurology distinguished progressive and nonprogressive conditions. A progressive course with global cognitive worsening in DEE is usually attributed to severe seizures and electroencephalographic abnormalities whose deleterious effects interfere with developmental processes both in an apparently healthy brain and in an anatomically compromised one. Next generation sequencing and functional studies have helped identifying and characterizing clinical conditions, each with a broad spectrum of clinical and anatomic severity corresponding to a variable level of neurodegeneration, such that both a rapidly progressive course and considerably milder phenotypes with no obvious deterioration can be configured with mutations in the same gene. In this mini review, we present examples of genetic DEE that draw connections between neurodevelopmental and neurodegenerative disorders.

Abstract
AIM The aim of this article is to compare the performance of ZeroExpander® realised using PEEK or PA12 for the expansion of the maxilla in paediatric patients, exploring a new concept for approaching maxillary expansion with a metal-free fixed automatic appliance, based on pre-programmed set-up and anchored on deciduous teeth. MATERIALS It is a retrospective comparative study with a sample of 40 children in early or mixed deciduous dentition and transversal maxillary deficit, 20 treated with ZeroExpander® in PEEK and 20 treated with ZeroExpander® in PA12 with a mean age of 7.3 years old. The intraoral scans at T0 and at the end of the expansion were all performed by the same operator to obtain digital models on which were performed measurements by two other different operators. A descriptive analysis was conducted using frequencies and percentages for nominal variables and means and standard deviations for continuous variables. CONCLUSION In cases of allergy or hypersensitivity to metals or to specific chronic or acute pathological conditions, which may require periodic magnetic resonance imaging (MRI), it may not be possible to use traditional and metal fixed expansion devices. Moreover the concept of autonomous driving in paediatric orthodontics is not only possible, but it is and will be more real and very useful in the future. The "ortho-paediatric dentistry concept" will increase the range of benefits for children and their families which, in addition to care and thanks to technology, demand well-being, safety, comfort and quality of life beyond clinics.

Abstract
Every year, the olive oil industry generates a substantial amount of pomace, a semi-solid residue made up of skin, pulp, pit, and kernel fragments. Rather than being disposed of, the pomace can be dried and transported to an extraction facility where pomace oil can be extracted. Utilizing its high thermal capacity, the extracted pomace can be used as a supplementary fuel in the drying process, resulting in the production of ashes. In this study, the effect of pomace waste applied to the soil was investigated by testing two mixtures with different proportions of de-oiled pomace flour and kernel ash (50:50 and 70:30, respectively) in powder and pellet form. We used a dual approach, evaluating the effects of the mixtures on both soil communities and plant physiology and productivity, to assess the actual usability of the fertilizer in agriculture. The biomarker approach was valuable in assessing the sublethal effects of the two mixtures in powder form in soil. After 30 days of exposure, the bioindicator organism Eisena fetida showed lipid peroxidation, glutathione S-transferase and lactate dehydrogenase levels similar to the control, while lysozyme activity was reduced in all treatments. The powder mixture was lethal to the tomato plants, while there was no evidence of any damage to the olive trees. During 60 days of monitoring, both mixtures in pellet form showed a slight increase in physiological parameters, suggesting a benefit to the photosynthetic system. The improved carbon assimilation in tomato plants treated with the mixtures results in increased plant productivity, both in terms of number and weight of fruits, while maintaining the antioxidant content. This study paves the way for the use of the pomace mixture as a soil improver, thus increasing the value of this waste product.

Abstract
BACKGROUND AND PURPOSE Physiotherapy is gaining a central role in oncology. However, the training and competencies needed by physiotherapists in oncology rehabilitation are still unclear. This study aims to articulate the training trajectory of physiotherapists in oncology rehabilitation from entry-level education to advanced education degrees. METHODS Qualitative focus group study following a 'Reflexive Thematic Analysis' for data analysis. Participants were Italian physiotherapists with expertise in Oncology Rehabilitation (either clinically or academically) and Physiotherapy Bachelor of Science (BSc) course leaders, selected through purposive sampling. RESULTS Two focus groups were conducted with 14 participants. Six themes were developed: 1. 'Entry-Level Education in Oncology Rehabilitation: Let's Have a Taste', as the BSc introduces oncology rehabilitation. 2. 'Basic Knowledge: Building up the Library' as students acquire basic knowledge on oncology rehabilitation during their BSc; 3. 'Learning by Experience: The Relevance of the Placement' to answer the question "Is this the right road for me?"; 4. 'Clinical Reasoning and Competencies in Oncology Rehabilitation Embedded in Uncertainty' because oncology physiotherapists need to deal with the uncertainty of their patients' status; 5. 'Advanced Education Degree Skills: from Appetiser to the Main Course', as advanced education degree courses allow for becoming an expert in the field; 6. 'A Call to Action for Physiotherapists: Prevention-Diagnosis-Survivorship & End of Life', to realise their critical role in all the phases of the oncology path. CONCLUSIONS The BSc in Physiotherapy provides a foundation for future physiotherapists to understand oncology rehabilitation, but advanced education is necessary for expertise. The findings of this study have important implications for creating a shared physiotherapy curriculum in oncology rehabilitation. IMPLICATION FOR PHYSIOTHERAPY PRACTICE This study has significant implications for improving physiotherapy curricula in oncology rehabilitation, positively impacting the skills and competencies of practitioners in this paramount field.

Abstract
BACKGROUND Myxoid glioneuronal tumor (MGT) is a benign glioneuronal neoplasm recently introduced in the World Health Organization (WHO) classification of the central nervous system (CNS) tumors. MGTs are typically located in the septum pellucidum, foramen of Monro or periventricular white matter of the lateral ventricle. They were previously diagnosed as dysembryoplastic neuroepithelial tumors (DNT), showing histological features almost indistinguishable from classical cortical DNT. Despite that, MGTs have been associated with a specific dinucleotide substitution at codon 385 in the platelet-derived growth factor receptor alpha (PDGFRA) gene, replacing a lysine residue with either leucine or isoleucine (p. LysK385Leu/Iso). This genetic variation has never been described in any other CNS tumor. MATERIALS AND METHODS Thirty-one consecutive tumors, previously diagnosed as DNTs at the Meyer Children's Hospital IRCCS between January 2010 and June 2021 were collected for a comprehensive study of their clinical, imaging, pathological features, and molecular profile. RESULTS In six out of the thirty-one tumors we had previously diagnosed as DNTs, we identified the recurrent dinucleotide mutation in the PDGFRA. All six tumors were typically located within the periventricular white matter of the lateral ventricle and in the septum pellucidum. We then renamed these lesions as MGT, according to the latest WHO CNS classification. In all patients we observed an indolent clinical course, without recurrence. CONCLUSION MGT represent a rare but distinct group of neoplasm with a typical molecular profiling, a characteristic localization, and a relative indolent clinical course.

Abstract
Glioblastoma (GBM) is a common and deadly form of brain tumor in adults. Dysregulated metabolism in GBM offers an opportunity to deploy metabolic interventions as precise therapeutic strategies. To identify the molecular drivers and the modalities by which different molecular subgroups of GBM exploit metabolic rewiring to sustain tumor progression, we interrogated the transcriptome, the metabolome, and the glycoproteome of human subgroup-specific GBM sphere-forming cells (GSC). L-fucose abundance and core fucosylation activation were elevated in mesenchymal (MES) compared with proneural GSCs; this pattern was retained in subgroup-specific xenografts and in subgroup-affiliated human patient samples. Genetic and pharmacological inhibition of core fucosylation significantly reduced tumor growth in MES GBM preclinical models. Liquid chromatography-mass spectrometry (LC-MS)-based glycoproteomic screening indicated that most MES-restricted core-fucosylated proteins are involved in therapeutically relevant GBM pathological processes, such as extracellular matrix interaction, cell adhesion, and integrin-mediated signaling. Selective L-fucose accumulation in MES GBMs was observed using preclinical minimally invasive PET, implicating this metabolite as a potential subgroup-restricted biomarker.Overall, these findings indicate that L-fucose pathway activation in MES GBM is a subgroup-specific dependency that could provide diagnostic markers and actionable therapeutic targets. SIGNIFICANCE Metabolic characterization of subgroup-specific glioblastoma (GBM) sphere-forming cells identifies the L-fucose pathway as a vulnerability restricted to mesenchymal GBM, disclosing a potential precision medicine strategy for targeting cancer metabolism.

Abstract
Medulloblastoma (MB), one of the most malignant brain tumors of childhood, comprises distinct molecular subgroups, with p53 mutant sonic hedgehog-activated (SHH-activated) MB patients having a very severe outcome that is associated with unfavorable histological large cell/anaplastic (LC/A) features. To identify the molecular underpinnings of this phenotype, we analyzed a large cohort of MB developing in p53-deficient Ptch+/- SHH mice that, unexpectedly, showed LC/A traits that correlated with mTORC1 hyperactivation. Mechanistically, mTORC1 hyperactivation was mediated by a decrease in the p53-dependent expression of mTORC1 negative regulator Tsc2. Ectopic mTORC1 activation in mouse MB cancer stem cells (CSCs) promoted the in vivo acquisition of LC/A features and increased malignancy; accordingly, mTORC1 inhibition in p53-mutant Ptch+/- SHH MB and CSC-derived MB resulted in reduced tumor burden and aggressiveness. Most remarkably, mTORC1 hyperactivation was detected only in p53-mutant SHH MB patient samples, and treatment with rapamycin of a human preclinical model phenocopying this subgroup decreased tumor growth and malignancy. Thus, mTORC1 may act as a specific druggable target for this subset of SHH MB, resulting in the implementation of a stringent risk stratification and in the potentially rapid translation of this precision medicine approach into the clinical setting.

Abstract
Abstract
Aims
Mitral valve prolapse (MVP) is frequently found in the population (3% prevalence). MVP prognosis is generally benign; however, malignant arrhythmias and increased risk of arrhythmic sudden cardiac death (0.2% to 0.4% per year) was described in patients, usually female, mostly affected by bileaflet myxomatous disease, mid-systolic click, ripolarization abnormalities in the inferior leads, and complex ventricular arrhythmias with polymorphic/right bundle branch block morphology, without significant regurgitation. The actual burden, risk stratification, and treatment of the so-called arrhythmic MVP are unknown.
Methods
Z.T. is a 32 years old woman who was admitted to the Emergency Department (ED) with left arm and face paraesthesia. She also reported having suffered from migraine and hypertension a few days earlier. ECG: normal sinus rhythm, no ripolarization abnormalities. CT and MRI were executed to rule out cerebral ischaemic events and both resulted negative. No SCD was reported in the anamnesis and the patient denied syncopal and pre-syncopal episodes. Z.T. had undergone cardiologic examination for tachycardia 2 years before the present events, during her second pregnancy (she produced no documentation to this effect). No chronic therapy. Low blood pressure at home. Due to the patient’s cardiologic history, ECG monitoring was performed, evidencing frequent premature ventricular beats (PVBs), some couples, and triplets. Cardiologic evaluation was requested. On Echocardiogram: Normal bi-ventricular function. Bileaflet mitral valve prolapse with myxomatous degeneration. Minimal valve regurgitation. Mitral annulus disjunction. TE echocardiogram: no PFO. Nadolol 20 mg was prescribed and after 24 h of observation the patient was discharged, scheduling Holter ECG, cardiac MRI and arrhythmologic evaluation.
Results
One month later, the patient reported intolerance to nadolol due to hypotension and pre-syncopal episodes during postural changes. Holter ECG revealed: polymorphic PVBs (2009), couples (383), triplets (40). Cardiac MRI: mitral valve prolapse (11 mm), mitral annulus disjunction (8mm) systolic curling (3mm). No LGE. No oedema. Nadolol was discontinued and substituted with bisoprolol 2.5 mg. Physical activity was discouraged; Ergometric test and Holter ECG were ordered under treatment with bisoprolol. The Ergometric test revealed reduced extrasystolia during physical effort, isolated PVBs and some couples during recovery. Holter ECG revealed continuing isolated PVBs (980) and some couples (37). No complex arrhythmia.
Conclusion
Z.T. is affected by an arrhythmic MVP syndrome characterized by complex PVBs, mitral annular disjunction, and systolic curling, which have been described by pathological and cardiac magnetic resonance studies in sudden death victims. However, Z.T. is asymptomatic: no ECG ripolarization abnormalities at rest and good response to medical therapy with β-blockers.
Our patient strategy was conservative and we decided to follow up with trimestral cardiologic evaluation and Holter ECG. Further research is needed to best identify high-risk patients and suggest treatments aimed to prevent sudden death.

A nasopharyngeal swab for SARS-CoV-2 test was done, being positive. Methods and results Chest TC demonstrated ground glass bilateral pneumonia. Laboratory test showed WBC 10680/mmc, CRP 20 mg/l, TnT 0.03 ng/l, NTproBNP 147 ng/l. The liver and kidney function were within normal values. ECG was normal. He was treated with high flow oxygen (cPAP), enoxaparin, dexamethasone, doxycycline. After an initial improvement, dyspnoea got worse in 8th day, with the evidence of a new rise of inflammatory markers (PCR 95 mg/l, IL6 49 pg/ml) and the clinical new onset of cardiac rubbings on medical examination. The ECG revealed a sinus rhythm with T wave inversion everywhere. TnT remained normal. Echocardiography revealed a normal ventricular function, without segmentary alterations, absence of valvular disease. A mild pericardial effusion was evidenced, without signs of tamponade. We treated the patient with tocilizumab, after exclusion of other active infective foci. The clinical response was good, the patient was progressively weaned by oxygen and he was discharged asymptomatic. After 15 days, for ECG alterations persistence, despite no signs of ACS, a Coronary TC was done and a subcritical multivessel coronary artery disease was demonstrated: a subcritical IVA stenosis and a calcific MO. Conclusions In conclusion we report a successful treatment of COVID pneumonia likely complicated by acute pericarditis, and we observe that in these patients hypoxemia and cytochine storm possibly bring out silent vascular diseases, otherwise neglected.

Abstract
Throughout history, technological progress has transformed population health, but the distributional effects of these gains are unclear. New substitutes for older, more expensive health technologies can produce convergence in population health outcomes but may also be prone to elite capture and thus divergence. We study the case of penicillin using detailed historical mortality statistics and exploiting its abruptly timed introduction in Italy after WWII. We find that penicillin reduced both the mean and standard deviation of infectious disease mortality, leading to substantial convergence across disparate regions of Italy. Our results do not appear to be driven by competing risks or confounded by mortality patterns associated with WWII.

Abstract
BACKGROUND Pharmacogenetics investigates the response to pharmacological treatments based on individual genetic background. Actually, numerous pharmacogenetic tests help to predict the response to drugs used in different medical areas, contributing to the so-called personalized medicine. OBJECTIVE This review aims to update the available data on the genotype-guided treatment with both the anticoagulant and antiplatelet agents. Moreover, it shed light on the pitfalls still contrasting the implementation of cardiovascular pharmacogenetics. METHODS A review of the literature on the studies investigating the effects of the genotype-guided anticoagulant and antiplatelet treatment was performed. RESULTS Considering the large use of antithrombotic drugs, pharmacogenetics has particular importance in this field. Several polymorphisms influence the response to both anticoagulant and antiplatelet agents, and tests, based on their identification, are now available. CONCLUSIONS Recent randomized clinical trials demonstrated that pharmacogenetics might successfully contribute to optimizing the antiplatelet therapy also in patients particularly complicated to treat. However, despite accumulating evidence on the utility and feasibility of some pharmacogenetics tests, several barriers still contrast their implementation into clinical practice.

Abstract
The emergency caused by Covid-19 pandemic raised interest in studying lifestyles and comorbidities as important determinants of poor Covid-19 prognosis. Data on tobacco smoking, alcohol consumption and obesity are still limited, while no data are available on the role of e-cigarettes and heated tobacco products (HTP). To clarify the role of tobacco smoking and other lifestyle habits on COVID-19 severity and progression, we designed a longitudinal observational study titled COvid19 and SMOking in ITaly (COSMO-IT). About 30 Italian hospitals in North, Centre and South of Italy joined the study. Its main aims are: 1) to quantify the role of tobacco smoking and smoking cessation on the severity and progression of COVID-19 in hospitalized patients; 2) to compare smoking prevalence and severity of the disease in relation to smoking in hospitalized COVID-19 patients versus patients treated at home; 3) to quantify the association between other lifestyle factors, such as e-cigarette and HTP use, alcohol and obesity and the risk of unfavourable COVID-19 outcomes. Socio-demographic, lifestyle and medical history information will be gathered for around 3000 hospitalized and 700-1000 home-isolated, laboratory-confirmed, COVID-19 patients. Given the current absence of a vaccine against SARS-COV-2 and the lack of a specific treatment for COVID-19, prevention strategies are of extreme importance. This project, designed to highly contribute to the international scientific debate on the role of avoidable lifestyle habits on COVID-19 severity, will provide valuable epidemiological data in order to support important recommendations to prevent COVID-19 incidence, progression and mortality.

Abstract
Cytopathological analyses of bronchial washings (BWs) collected during fibre‐optic bronchoscopy are often inconclusive for lung cancer diagnosis. To address this issue, we assessed the suitability of conducting molecular analyses on BWs, with the aim to improve the diagnosis and outcome prediction of lung cancer. The methylation status of RASSF1A, CDH1, DLC1 and PRPH was analysed in BW samples from 91 lung cancer patients and 31 controls, using a novel two‐colour droplet digital methylation‐specific PCR (ddMSP) technique. Mutations in ALK, BRAF, EGFR, ERBB2, KRAS, MAP2K1, MET, NRAS, PIK3CA, ROS1 and TP53 and gene fusions of ALK, RET and ROS1 were also investigated, using next‐generation sequencing on 73 lung cancer patients and 14 tumour‐free individuals. Our four‐gene methylation panel had significant diagnostic power, with 97% sensitivity and 74% specificity (relative risk, 7.3; odds ratio, 6.1; 95% confidence interval, 12.7–127). In contrast, gene mutation analysis had a remarkable value for predictive, but not for diagnostic, purposes. Actionable mutations in EGFR, HER2 and ROS1 as well as in other cancer genes (KRAS, PIK3CA and TP53) were detected. Concordance with gene mutations uncovered in tumour biopsies was higher than 90%. In addition, bronchial‐washing analyses permitted complete patient coverage and the detection of additional actionable mutations. In conclusion, BWs are a useful material on which to perform molecular tests based on gene panels: aberrant gene methylation and mutation analyses could be performed as approaches accompanying current diagnostic and predictive assays during the initial workup phase. This study establishes the grounds for further prospective investigation.

Abstract
BACKGROUND AND OBJECTIVE Symptoms negatively impact the quality of life and long-term prognosis of patients with chronic obstructive pulmonary disease (COPD). Little is known about the relationship linking airway inflammation and symptoms in stable COPD. In this study, we evaluated whether respiratory symptoms in COPD are related to sputum inflammatory cellular profile and whether symptom changes are associated with changes in airway inflammation. METHODS A total of 40 patients with stable COPD with moderate-to-severe airflow obstruction were enrolled. Patients were visited weekly over 4 weeks. At each visit, patients underwent clinical assessments, lung function tests and sputum induction. Patients recorded daily dyspnoea, sputum and cough scores. RESULTS The changes between two consecutive visits in the percent of sputum neutrophils and eosinophils were related to the changes in the cough (P < 0.001; r = 0.63) and dyspnoea scores (P < 0.001; r = 0.58) of the prior week. Furthermore, using regression analyses, we were able to demonstrate that changes in the cough score were specifically associated to the change in neutrophils, while changes in the dyspnoea score and use of rescue medications were associated with changes in eosinophils numbers. CONCLUSION Our study showed an association between symptoms and the sputum inflammatory profile. In particular, changes in symptoms (cough and dyspnoea) were correlated with changes in the specific sputum inflammatory cell components of airway inflammation (neutrophils and eosinophils, respectively), providing novel information on the mechanisms of disease manifestation.

Abstract
Inflammation and tissue regeneration follow tissue damage, but little is known about how these processes are coordinated. Tirone et al. show that alternative redox forms of high mobility group box 1 (HMGB1), the “alarmin” signal released by damaged cells, trigger inflammation or tissue repair after injury by interacting with distinct receptors and that a nonoxidizable HMGB1 mutant promotes regeneration without exacerbating inflammation. Inflammation and tissue regeneration follow tissue damage, but little is known about how these processes are coordinated. High Mobility Group Box 1 (HMGB1) is a nuclear protein that, when released on injury, triggers inflammation. We previously showed that HMGB1 with reduced cysteines is a chemoattractant, whereas a disulfide bond makes it a proinflammatory cytokine. Here we report that fully reduced HMGB1 orchestrates muscle and liver regeneration via CXCR4, whereas disulfide HMGB1 and its receptors TLR4/MD-2 and RAGE (receptor for advanced glycation end products) are not involved. Injection of HMGB1 accelerates tissue repair by acting on resident muscle stem cells, hepatocytes, and infiltrating cells. The nonoxidizable HMGB1 mutant 3S, in which serines replace cysteines, promotes muscle and liver regeneration more efficiently than the wild-type protein and without exacerbating inflammation by selectively interacting with CXCR4. Overall, our results show that the reduced form of HMGB1 coordinates tissue regeneration and suggest that 3S may be used to safely accelerate healing after injury in diverse clinical contexts.

Abstract
SummaryPurified active matrix metalloproteinase-2 (MMP-2) is able to promote platelet aggregation. We aimed to assess the role of MMP-2 expressed in atherosclerotic plaques in the platelet-activating potential of human carotid plaques and its correlation with ischaemic events. Carotid plaques from 81 patients undergoing endarterectomy were tested for pro-MMP-2 and TIMP-2 content by zymography and ELISA. Plaque extracts were incubated with gel-filtered platelets from healthy volunteers for 2 minutes before the addition of a subthreshold concentration of thrombin receptor activating peptide-6 (TRAP-6) and aggregation was assessed. Moreover, platelet deposition on plaque extracts immobilised on plastic coverslips under high shear-rate flow conditions was measured. Forty-three plaque extracts (53%) potentiated platelet aggregation (+233 ± 26.8%), an effect prevented by three different specific MMP-2 inhibitors (inhibitor II, TIMP-2, moAb anti-MMP-2). The pro-MMP-2/TIMP-2 ratio of plaques potentiating platelet aggregation was significantly higher than that of plaques not potentiating it (3.67 ± 1.21 vs 1.01 ± 0.43, p<0.05). Moreover, the platelet aggregation-potentiating effect, the active-MMP-2 content and the active MMP-2/pro-MMP-2 ratio of plaque extracts were significantly higher in plaques from patients who developed a subsequent major cardiovascular event. In conclusion, atherosclerotic plaques exert a prothrombotic effect by potentiating platelet activation due to their content of MMP-2; an elevated MMP-2 activity in plaques is associated with a higher rate of subsequent ischaemic cerebrovascular events.

Abstract
OBJECTIVE During climacteric the reduction or interruption of estrogenic stimulus determines a gradual atrophy of the tissues of the urogenital tract.Vulvovaginal atrophy can be cause of dryness, itch, burning, and dyspareunia. Vulvovaginal atrophy is associated also with depression. Hence the importance of an appropriate treatment of the vulvovaginal atrophy. Between therapeutic options we can add, particularly for women who suffer only from vaginal symptoms, the spa therapy that uses mineral waters with benefic effects on vaginal tissue wellness and health. On the basis of considerations described above and on the insufficient literature data, the objective of our single-arm pilot study has been to evaluate, in women suffering from vulvovaginal atrophy, the effects and safety of a vaginal douching cycle with sulphurous mineral water and impact on depression disorder frequently observed. PATIENTS AND METHODS The study was conducted on 24 women affected by vulvovaginal atrophy; mean age:57±11 years; age range:42-81 years. The subjects were treated, for 2 weeks, with sulphurous vaginal douching from Terme of Telese S.p.A. (Benevento-Italy). At the beginning and at the end of the SPA treatment the following symptoms were evaluated: dryness, burning, itch, dyspareunia and leucorrhoea (using VAS scale); the impact on psychological distress (using S.D.S. Zung-test). RESULT At the end of the spa treatment, the mean values±SD, compared to baseline, have showed a significant (p<0.05) reduction in leucorrhoea (-88%), in vulvar itch (-79%), in vaginal burning (-71%), in vaginal dryness (-65%) with an improvement of psichological distress as demonstrated by S.D.S. Zung-test. CONCLUSION The data of this single-arm pilot clinical trial show that the sulphurous vaginal douching cycle can be considered very useful in women suffering from vulvovaginal atrophy with improving of the quality of life and social relationship.

Abstract
BACKGROUND The optimal method for specimen preparation of endobronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA) is still controversial. This study aims to compare several techniques available for EBUS-TBNA specimen acquisition and processing, in order to identify the best performing technique. METHODS We retrospectively reviewed the data of 199 consecutive patients [male, 73%; median age, 64 years (IQR: 52-74 years)] undergoing EBUS-TBNA at our institution from 2012 through 2014 for diagnosis of hilar-mediastinal lymph node enlargement suspect of neoplastic (n=139) or granulomatous (n=60) disease. All procedures were performed by two experienced bronchoscopists, under conscious sedation and local anaesthesia, using 21/22-Gauge (G) needle, without rapid on-site evaluation (ROSE). Five specimen-processing techniques were used: cytology slides in 42 cases (21%); cell-block in 25 (13%); core-tissue in 60 (30%); combination of cytology slides and core-tissue in 51 (26%); combination of cytology slides and cell-block in 21 (10%). To assess the diagnostic accuracy of each tissue-processing technique we compared the EBUS-TBNA results to those obtained with surgical lymphadenectomy, or 1-year follow-up in non-operated patients. RESULTS Diagnostic yield, accuracy and area under the curve (AUC) were as follows. Cytology slides: 81%, 80%, 0.90; cell-block: 48%, 33%, 0.67; core-tissue: 87%, 99%, 0.96; cytology slides + core-tissue: 80%, 100%, 1.00; cytology slides + cell-block: 86%, 100%, 1.00. Cytology slides and core-tissue method showed non-significantly different diagnostic yield (P=0.435) and AUC (P=0.152). CONCLUSIONS In our single-institution experience, cytology slides and core-tissue preparations demonstrated high and similar diagnostic performance. Cytology slides combination with core-tissue or cell-block showed the highest performance, however these combination methods were more resource-consuming.

Abstract
In the last decade, progenitor cells isolated from dissociated endometrial tissue have been the subject of many studies in several animal species. Recently, endometrial cells showing characteristics of mesenchymal stem cells (MSC) have been demonstrated in human, pig and cow uterine tissue samples. The aim of this study was the isolation and characterization of stromal cells from the endometrium of healthy bitches, a tissue that after elective surgery is routinely discarded. Multipotent stromal cells could be isolated from all bitches enrolled in the study (n = 7). The multipotency of cells was demonstrated by their capacity to differentiate into adipocytic, osteocytic and chondrocytic lineages. Clonogenicity and cell proliferation ability were also tested. Furthermore, gene expression analysis by RT-PCR was used to compare the expression of a set of genes (CD44, CD29, CD34, CD45, CD90, CD13, CD133, CD73, CD31 CD105, Oct4) with adipose tissue-derived MSC. Stromal cells isolated from uterine endometrium showed similar morphology, ability of subculture and plasticity, and also expressed a panel of genes comparable with adipose tissue-derived MSC. These data suggest that endometrial stromal cells fulfil the basic criteria proposed by the "Mesenchymal and Tissue Stem Cell Committee of the International Society for Cellular Therapy" for the identification of mesenchymal stem cells. Although endometrial mesenchymal stem cells (EnMSC) showed a lower replicative ability in comparison with adipose tissue-derived MSC, they could be considered a cell therapeutic agent alternative to adipose tissue or bone marrow-derived MSC in dog.

Abstract
Embryonic VE-Cadherin-expressing progenitors (eVE-Cad+), including hemogenic endothelium, have been shown to generate hematopoietic stem cells and a variety of other progenitors, including mesoangioblasts, or MABs. MABs are vessel-associated progenitors with multilineage mesodermal differentiation potential that can physiologically contribute to skeletal muscle development and regeneration, and have been used in an ex vivo cell therapy setting for the treatment of muscular dystrophy. There is currently a therapeutic need for molecules that could improve the efficacy of cell therapy protocols; one such good candidate is nitric oxide. Several studies in animal models of muscle dystrophy have demonstrated that nitric oxide donors provide several beneficial effects, including modulation of the activity of endogenous cell populations involved in muscle repair and the delay of muscle degeneration. Here we used a genetic lineage tracing approach to investigate whether the therapeutic effect of nitric oxide in muscle repair could derive from an improvement in the myogenic differentiation of eVE-Cad+ progenitors during embryogenesis. We show that early in vivo treatment with the nitric oxide donor molsidomine enhances eVE-Cad+ contribution to embryonic and fetal myogenesis, and that this effect could originate from a modulation of the properties of yolk sac hemogenic endothelium.

Abstract
microRNAs (miRNAs) are short noncoding RNAs, which regulate gene expression post-transcriptionally and play crucial roles in relevant biological and pathological processes. Here, we investigated the putative role of miRNAs in modulating the tumor-initiating potential of mouse medulloblastoma (MB)-derived cancer stem cells (CSCs). We first subjected bona fide highly tumorigenic (HT) CSCs as well as lowly tumorigenic MB CSCs and normal neural stem cells to miRNA profiling, which identified a HT CSC-specific miRNA signature. Next, by cross-checking CSC mRNA/miRNA profiles, we pinpointed miR-135a as a potential tumor suppressor gene, which was strongly downregulated in HT CSCs as well as in the highly malignant experimental tumors derived from them. Remarkably, enforced expression of miR-135a in HT CSCs strongly inhibited tumorigenesis by repressing the miR-135a direct target gene Arhgef6. Considering the upregulation of Arhgef6 in human MBs and its involvement in mediating experimental medulloblastomagenesis, its efficient suppression by miR-135a might make available an effective therapeutic strategy to selectively impair the tumorigenic potential of MB CSCs.

Abstract
Chronic obstructive pulmonary disease (COPD) and asthma are lung inflammatory diseases that represent major public health problems. The primary, and often unique, method to evaluate lung function is spirometry, which reflects disease severity rather than disease activity. Moreover, its measurements strictly depend on patient's compliance, physician's expertise and data interpretation. The limitations of clinical history and pulmonary function tests have encouraged focusing on new possible tracers of diseases. The increase of the inflammatory response in the lungs represents an early pathological event, so biological markers related to inflammation may play key roles in earlier diagnosis, evaluation of functional impairment and prognosis. Biomarkers are measurable indicators associated with the presence and/or severity of a biological or pathogenic process, which may predict functional impairment, prognosis and response to therapy. The traditional approach based on invasive techniques (bronchoalveolar lavage and biopsies) may be replaced, at least in part, by using less invasive methods to collect specimens (sputum and blood), in which biomarkers could be measured. Proteomics, by the association between different protein profiles and pathogenic processes, is gaining an important role in pulmonary medicine allowing a more precise discrimination between patients with different outcomes and response to therapy. The aim of this review was to evaluate the use of biomarkers of airway inflammation in the context of both research and clinical practice.

Abstract
Physical exercise is associated with reduced risk of heart disease, type II diabetes mellitus, and overall mortality. However, growing evidence shows that physical activity can also improve cognitive function and may lower the risk of developing dementia, but Randomized Clinical Trials gave mixed results. Aim of this article was to review the knowledge available in literature on the effects of physical activity on cognition and the suggested possible mechanisms involved in these effects. Our group have planned a trial aiming to evaluate the effectiveness of physical activity in preventing or delaying the cognitive decline in individuals at risk of developing dementia. Beside the effects of exercise on cognition are not fully defined, also the mechanisms underlying the benefits of physical activity on cognitive sphere are not completely known. Recently the SIRT1 loss is both closely associated with accumulation of beta amyloid and tau protein in AD patients. Although there is no specific exercise that can be recommended, the available evidence suggests that practicing more types of physical activity is particularly advantageous. It is important to explore further mechanisms involved in the pathogenesis of the AD in order to be able to identify new and effective target treatment, including physical activity.

Abstract
The radioiodine administration is a standard therapeutic approach to both benign thyroid diseases, such as hyperthyroidism, and carcinomas. The high administered (131)I activities are of radiation protection concern, due to relevant patient residual contamination. The aim of this work was to develop a new procedure based on external radiometric surveys and on a mathematical model in order to estimate the (131)I activity in patients undergoing hyperthyroidism radioiodine therapy. In the first stage of this study, a suitable detector was chosen and its response vs. activity was characterized. The experimental verification was performed measuring the ambient dose equivalent rate from patients receiving radioiodine administration. The results confirm the reliability of the proposed method, as shown by the slight differences between the administered activities and the ones calculated from external measurements. Furthermore, the same procedure was applied to detect the percentage residual activity in patients at two preset time intervals: 4 hours and 4 days after the radioiodine administration. The obtained results clearly highlight that the method can ensure a level of reliability compatible with the radiation protection purposes.

Abstract
OBJECTIVE Failure to identify patients in whom non-invasive ventilation (NIV) would be unsuccessful may cause inappropriate delay in intubation. Aim of this study was to determine predictors of NIV failure. PATIENTS AND METHODS We retrospectively evaluated COPD patients, undergoing NIV for at least 12h because of hypercapnic acute respiratory failure. Univariable and multivariable analyses were performed on: age, gender, APACHE II and GCS, gas exchange at admission, during NIV and at discharge/death, length of stay. ROC analysis for pH START and APACHE II were performed. RESULTS Among 201 individuals enrolled, NIV failed in 50. In the logistic regression model only APACHE II was found to have an independent effect on the outcome (p < 0.0001, OR 1.179, 95% CI 1.101-1.263 as quantitative variable; p < 0.0001, OR 3.753, 95% CI 1.798-7.835, as qualitative variable, > 20.5). CONCLUSIONS APACHE II may be a crucial parameter in predicting NIV failure; further multicentric studies are needed to better define NIV indications.

Abstract
BACKGROUND The role of surgical biopsy for interstitial lung disease (ILD) is controversial, because of possible postoperative morbidity and mortality. We aimed to assess the efficacy and safety of surgical biopsy for ILD. METHODS We retrospectively analysed the diagnostic performance and the postoperative complications of 161 consecutive surgical lung biopsy procedures carried out in suspected ILD cases that were undefined after multidisciplinary clinico-radiological evaluation. In 151 cases (93.8%) the biopsy was performed by video-assisted thoracoscopic surgery (VATS), in 6.2% by limited thoracotomy. RESULTS A specific histological diagnosis was obtained in 154 (95.7%) of the surgically biopsied patients, while 4.3% remained histologically unclassified. The predominant histological patterns were sarcoidosis (29.8 %), usual interstitial pneumonia/idiopathic pulmonary fibrosis (UIP/IPF) (24.2%), cryptogenic organizing pneumonia (18.6%) and nonspecific interstitial pneumonia (8.1%). The postoperative course was uneventful in 142 cases. In 19 patients (11.8%) we observed postoperative complications, predominantly prolonged air leakage (5.0% of all cases). Thirty-day postoperative mortality was 3.1%, mostly due to acute exacerbation of respiratory insufficiency. Postoperative mortality independently correlated with preoperative need of oxygen therapy (OR, 5.21; 95% CI, 1.19-22.95) and with UIP/IPF histology (OR, 5.67; 95% CI, 1.27-25.25). CONCLUSIONS Lung biopsy was performed mostly by VATS, with limited morbidity, and was effective in yielding a specific histologic diagnosis in the vast majority of undefined ILD cases. To optimize the outcome of surgical biopsy for specific diagnosis of ILD, this procedure should be performed only exceptionally in patients with critical respiratory illness as postoperative mortality risk in these subjects is exceedingly high.

Abstract
OBJECTIVES The aim of this study was to investigate if co-morbid conditions as hepatitis C virus infection and celiac disease may be associated to undifferentiated connective tissue disease. METHODS We studied retrospectively and prospectively 52 patients with diagnosis of undifferentiated connective tissue disease, subdivided, according to Vaz criteria, in systemic lupus erythematosus, systemic sclerosis and Sjögren's syndrome-like subgroups. Serological markers of celiac disease as anti-gliadin, anti-endomysium and anti-tissue transglutaminase antibodies were investigated. An esophagogastroduodenoscopy with duodenal biopsy and histological examination was proposed to patients with positive celiac disease serology. In addition antibodies directed to hepatitis C virus and total IgA-antibodies were investigated. RESULTS Six patients (11,5%) were positive for celiac disease serological tests although two of them were asymptomatic. Four patients underwent an esophagogastroduodenoscopy, showing total or subtotal villous atrophy at duodenal biopsies. Hepatitis C virus serology was negative in all patients and none had IgA deficiency. 83% of celiac patients showed a scleroderma-like phenotype. We observed a statistically higher incidence of autoimmune symptoms in patients with gluten sensitivity. Fatigue and myalgia regressed early after the beginning of gluten-free diet. CONCLUSIONS In our cohort of patients the prevalence of celiac disease was higher than that reported in the general population. We believe that all patients with diagnosis of undifferentiated connective tissue disease, especially those with a systemic sclerosis-like presentation, should be investigated for celiac disease, even in absence of gastrointestinal symptoms. Gluten-free diet should be early recommended to all patients having undifferentiated connective tissue disease and gluten sensitivity.

Abstract
BACKGROUND AND OBJECTIVE The chronic arthropathies currently appear to be a major cause of disability with a negative impact on quality of life and health care spending. The mud-bath therapy is a spa treatment that induces benefic effects in chronic rheumatic diseases. It has long been debated on the assumption that the mud-bath spa therapy could have adverse cardiovascular effects which often induce caution and even a contraindication to the use of this treatment in chronic arthropathies associated with cardiovascular alterations such as hypertension. The aim of this observational study was to investigate, in arthrorheumatic subjects, the effects of sulphureous mud-bath cycle on blood pressure and the possible appearance of adverse drug reaction. PATIENTS AND METHODS 169 patients, with age range 42-86 years, suffering by chronic arthropathies were treated with sulphureous mud-bath therapy for 2 weeks. According to the arterial pressure values, measured before the spa treatment, the patients considered were divided in three groups: with normal blood pressure (NOR group); with high blood pressure, after, the latter group was divided in IPET (patients in treatment with antihypertensive drugs) and IPENT (patients not in antihypertensive therapy). The arterial pressure values, maximum and minimum, expressed in mmHg, were detected in the first (T1) - sixth (T6) and twelfth (T12) day of spa treatment. The media arterial pressure values collected before and after T1, before and after T6, before and after T12 , before T1 and after T12 were compared. The data, presented as mean±SD, were compared with the paired Student t test. A p value ≤0.05 was considered significant. RESULTS The comparison between the mean values detected in pre and post T1, pre and post T6, pre and post T12 have showed that sulphureous mud-bath therapy induced a significant (p<0.05) reduction of arterial blood pressure values in patients suffering of chronic arthropathies with high blood pressure in antihypertensive therapy or not (IPET and IPENT groups); while in patients with normal blood pressure (NOR group) were observed modest reduction at the limit of statistical significance. Similarly, the comparison between the data detected at the end of sulphureous mud-bath therapy (post-T12) vs baseline (pre-T1) have demonstrated: in IPET and IPENT groups a significant (p<0,01) decrease of arterial blood pressure values; in NOR group very small decrease, this reduction is significant (p<0.05) only for maximum arterial pressure value. Were not observed adverse drug reaction. CONCLUSIONS The results of our study, in according with the few data in the literature, evidenced that is possible include the sulphureous mud-bath therapy in interdisciplinary therapeutic p rotocol of patients suffering of chronic arthropathies and arterial hypertension.

Abstract
Abacavir is a nucleoside reverse transcriptase inhibitor largely used as part of the antiretroviral therapy in Human Immunodeficiency Virus (HIV)-infected patients. Some individuals (2-9%) who start an abacavir treatment show an immunologic reaction indicated as hypersensitivity reaction syndrome (HSR) that is often responsible for therapy discontinuation and could represent a life-threatening event. Some studies demonstrated a correlation between this adverse reaction and the class I of the major histocompatibility complex (MHC) allele, HLA-B*57.01, in several populations, including Caucasians. Nowadays, International HIV treatment guidelines recommend the HLA-B*57.01 genotyping before abacavir administration to reduce the incidence of HSR. Both male and female HIV-infected patients were enrolled at the Infectious Diseases Division at the University Hospital of Salerno, and admitted to a prospective HLAB*57.01 screening. Genetic analysis was carried out through two sequential Real-Time PCR reactions in which Sybr-Green was used. Out of 248 patients, 215 were Italians from Southern Italy and 33 were coming from several non-EU members countries. All were genotyped: 6 Italians (2.8%) and 1 of the non-EU group (3%) were identified as HLAB*57.01 carriers. In this paper we present our experience in the field of abacavir pharmacogenetic and confirm the importance of Real Time PCR as a valid and cost-effective HLA-B*57.01 typing methodology.

Abstract
Somatic and germline duplications or activating mutations of AKT3 have been reported in patients with hemimegalencephaly and megalencephaly. We performed array comparative genomic hybridization on brain tissue and blood in 16 consecutive patients with symptomatic epilepsy due to focal or multilobar malformations of cortical development who underwent surgical treatment of epilepsy. One patient with infantile spasms and a dysplastic left frontal lobe harboured a somatic trisomy of the 1q21.1-q44 chromosomal region, encompassing the AKT3 gene, in the dysplastic brain tissue but not in blood and saliva. Histopathology revealed severe cortical dyslamination, a thin cortex in the premotor area with microgyri and microsulci, immature neurons with disoriented dendrites and areas of cortical heterotopia in the sub-cortical white matter. These cytoarchitectural changes are close to those defining type Ib focal cortical dysplasia. Immunohistochemistry in brain specimens showed hyperactivation of the PI3K/AKT/mTOR pathway. These findings indicate that AKT3 upregulation may cause focal malformations of cortical development. There appears to be an etiologic continuum between hemimegalencephaly and focal cortical dysplastic lesions. The extent of brain malformations due to AKT3 upregulation may be related to the embryonic stage when the post-zygotic gene alteration occurs.

Abstract
OBJECTIVE Chronic obstructive pulmonary disease (COPD) has been associated with a high frequency of arrhythmias. Atrial fibrillation (AF) is one of the most common arrhythmias and causes substantial morbidity and mortality. Emerging risk factors for the development of AF include a variety of breathing disorders like COPD. Few studies have analyzed the role of reduced lung function and respiratory acidosis in predicting AF. Aim of the current study was to investigate the role of hypercapnia, pulmonary systolic hypertension and lung function impairment in COPD patients, as risk factors for atrial fibrillation development. PATIENTS ANDV METHODS We evaluated a population of individuals consecutively hospitalized for COPD exacerbation and hypercapnic respiratory failure between January 2012 and January 2013; among them we selected a subgroup of patients presenting a paroxysmal episode of atrial fibrillation. All patients underwent pulmonary function tests, haemogasanalysis, electrocardiogram and transthoracic echocardiography. RESULTS Among the 193 subjects evaluated, 35 individuals with AF and COPD were enrolled in the study. Risk of new AF was higher in those subjects with lower FEV1 and higher PaCO2 values, also there was a significantly increased prevalence of AF in patients with higher value of Pulmonary Artery Systolic Pressure (PASP), obtained by transthoracic echocardiography. Linear correlation between variables revealed a direct relationships between hypercapnia and PASP and left and right atrial areas. CONCLUSIONS Impaired pulmonary function, hypercapnia and high values of PASP are independent predictors of incident AF.

Abstract
BACKGROUND Apart from the underlying cardiovascular (CV) risk associated with migraine, both triptans and ergotamines can induce vasoconstriction and potentially increase the risk of serious ischemic events. Because of the low frequency of such events in eligible patients, randomized controlled trials are not exhaustive to assess the drug-related CV risk. Observational studies are, therefore, an essential source of information to clarify this matter of concern. AIM The aim of this study was to systematically review the available published observational studies investigating the risk of serious CV events in triptan or ergotamine users, as compared to unexposed migraineur controls. METHODS We systematically searched MEDLINE and EMBASE electronic databases for cohort or case-control studies up to December 1, 2013. Studies retrieved from CDSR, DARE and HTA databases of the Cochrane Library were used for snowballing. Studies investigating the risk of any CV outcome in patients with a migraine diagnosis and exposed to triptans or ergotamines were considered for inclusion. Selection of studies, data extraction, and risk of bias assessment were conducted independently by two reviewers. Pooled odds ratios (ORs) with 95% confidence interval (95% CI) were computed using a random-effects model for studies and outcomes judged eligible for quantitative data synthesis. RESULTS From a total of 3370 citations retrieved, after duplicate removal and screening, only four studies met the inclusion criteria (three nested case-control analyses and one retrospective cohort study). These studies investigated the risk of different CV outcomes associated with either the recency or the intensity of exposure to the studied drugs. As for the intensity of use, the pooled OR of serious ischemic events was 2.28 (95% CI 1.18-4.41; I (2 )= 0%) for ergotamine use (two studies), whereas for triptans (three studies) it was 0.86 (95% CI 0.52-1.43; I (2 )= 24.5%). Recent use of ergotamines was not significantly associated with any CV outcome (only one available study). Two studies investigated the risk of stroke related to recent triptan use: the first study reported an OR of 0.90 (0.64-1.26), and the second one suggested an increased risk of 2.51 (1.10-5.71). In this case, because of the high degree of heterogeneity, results were not pooled. CONCLUSIONS To date, few comparative observational studies have investigated the CV safety of migraine-specific drugs in clinical practice. Evidence gathered here suggests that intense consumption of ergotamines may be associated with an increased risk of serious ischemic complications. As for triptans, available studies do not suggest strong CV safety issues, although no firm conclusions can be drawn. In particular, evidence on stroke risk is conflicting. However, if an increase of the absolute stroke risk in recently exposed patients does actually exist, it must be small. Overall, residual uncontrolled confounding factors reduce the confidence in the risk estimates collected from the included studies. Further investigations are needed to better define the risk for rare but serious CV events related to triptan and ergotamine use for treatment of migraine.

Abstract
PURPOSE The purpose of this study is to conduct a comparative analysis of the suspected adverse drug reactions (ADRs) associated with intravitreal bevacizumab, ranibizumab and pegaptanib in the WHO database in order to have a real-life information on these drugs, which now is only based on data coming from clinical trials. METHODS ADR reports for intravitreal use of bevacizumab, ranibizumab and pegaptanib from January 2002 to December 2012 were selected from the WHO-VigiBase. Reporting odds ratio (ROR) with confidence interval of 95 % and p value was calculated. The analysis was performed for drug-reaction pairs. The Medical Dictionary for Regulatory Activities (MedDRA) terminology for ADRs was used. RESULTS The analysis was performed on 3180 reports corresponding to 7753 drug-reaction pairs. Significant RORs for endophthalmitis and uveitis (1.90, 95 % confidence interval (CI) 1.48-2.43, and 10.62, 6.62-17.05, respectively) were retrieved for bevacizumab, and cerebrovascular accident and myocardial infarction produced significant ROR (1.54, 1.14-2.10 and 1.73, 1.18-2.53, respectively) for ranibizumab. Pegaptanib was significantly associated with visual impairment (1.98, 1.12-3.5, p = 0.02), nausea (3.29, 1.57-6.86, p < 0.001), vomiting (2.91, 1.2-7.07, p = 0.01) and drug hypersensitivity (8.75, 3.1-24.66, p < 0.001). CONCLUSIONS Our data showed an elevated disproportionality for cardiovascular ADRs in patients treated with ranibizumab and for infective ocular reactions in those treated with bevacizumab. No relevant safety issues were identified for pegaptanib. These findings suggest bevacizumab as a suitable choice for AMD therapy due to its effectiveness similar to that of ranibizumab, its favourable safety profile and for its lower cost.

Abstract
BACKGROUND Common variable immunodeficiency (CVID) is a heterogeneous disorder characterized by B-cell dysfunction and, in a subgroup, by expansion of CD21(low) B cells. The CD21(low) B cells display defects in early B-cell receptor (BCR) signaling resembling those of anergic B cells. OBJECTIVE We sought to investigate whether B cells from patients with CVID, like anergic B cells, have defects in extracellular signal-regulated kinase (ERK) phosphorylation and in endocytic trafficking of the BCR. METHODS Using flow cytometry, we evaluated phosphorylated ERK (pERK) expression and internalization of cross-linked BCR in B-cell subsets. The localization of internalized BCR to lysosome-associated membrane protein 1-positive late endosomes was evaluated with confocal microscopy. RESULTS Constitutive pERK levels were increased in naive and IgM(+) memory B cells of patients with CVID compared with those of healthy donors, whereas the pERK increment induced by BCR cross-linking was relatively reduced. Intravenous immunoglobulin administration enhanced these anomalies, but they appeared to be intrinsic to B cells from patients with CVID. Cross-linking-induced BCR endocytosis was decreased in the IgM(+) memory B cells, especially in those with a CD21(low) phenotype, but not in the naive B cells of patients with CVID with CD21(low) expansion. Internalized BCR localized normally to late endosomes. Pharmacologic inhibition of ERK phosphorylation suppressed BCR endocytosis in B cells of healthy patients and those with CVID. CONCLUSIONS The B cells of patients with CVID with CD21(low) B-cell expansion resemble anergic B cells based on high constitutive pERK expression. The IgM(+) memory B cells of these patients, especially those that are CD21(low), have a defect in BCR endocytosis seemingly caused by dysregulated ERK signaling.

Abstract
The functional diversity of the arterial and venous endothelia is regulated through a complex system of signalling pathways and downstream transcription factors. Here we report that the transcription factor Sox17, which is known as a regulator of endoderm and hemopoietic differentiation, is selectively expressed in arteries, and not in veins, in the mouse embryo and in mouse postnatal retina and adult. Endothelial cell-specific inactivation of Sox17 in the mouse embryo is accompanied by a lack of arterial differentiation and vascular remodelling that results in embryo death in utero. In mouse postnatal retina, abrogation of Sox17 expression in endothelial cells leads to strong vascular hypersprouting, loss of arterial identity and large arteriovenous malformations. Mechanistically, Sox17 acts upstream of the Notch system and downstream of the canonical Wnt system. These data introduce Sox17 as a component of the complex signalling network that orchestrates arterial/venous specification. The transcription factor Sox17 is required for the development of the vasculature in vertebrates. Here Corada et al. show that Sox17 acts downstream of Wnt signalling and upstream of Notch signalling in the regulation of artery and vein differentiation in mice.

Abstract
The embryonic endothelium is a known source of hematopoietic stem cells. Moreover, vessel-associated progenitors/stem cells with multilineage mesodermal differentiation potential, such as the ‘embryonic mesoangioblasts’, originate in vitro from the endothelium. Using a genetic lineage tracing approach, we show that early extra-embryonic endothelium generates, in a narrow time-window and prior to the hemogenic endothelium in the major embryonic arteries, hematopoietic cells that migrate to the embryo proper, and are subsequently found within the mesenchyme. A subpopulation of these cells, distinct from embryonic macrophages, co-expresses mesenchymal and hematopoietic markers. In addition, hemogenic endothelium-derived cells contribute to skeletal and smooth muscle, and to other mesodermal cells in vivo, and display features of embryonic mesoangioblasts in vitro. Therefore, we provide new insights on the distinctive characteristics of the extra-embryonic and embryonic hemogenic endothelium, and we identify the putative in vivo counterpart of embryonic mesoangioblasts, suggesting their identity and developmental ontogeny.

Abstract
AIM The study was undertaken to evaluate mineral trioxide aggregate (MTA) clinically and radiographically as a pulpotomy agent in immature permanent teeth whose pulps were exposed by a complicated crown fracture. MATERIALS AND METHODS Thirty incisors with exposed pulps in twenty-nine patients were examined for this retrospective study. According to exclusion criteria, only twenty-seven teeth were selected. Each tooth was treated with partial pulpotomy and the wounded pulp was covered with mineral trioxide aggregate. The children were recalled for clinical and radiographic evaluation at 3 months, 6 months, at approximately 12 months and 36 months. RESULTS Out of 27 cases, 22 were categorized as 'healed' and 1 as 'healing'. The remaining 4 ones highlighted persistent disease and needed further endodontic treatment. CONCLUSION MTA partial pulpotomy is an effective treatment in maintaining pulpal vitality and allowing physiological root development (apexogenesis).

Abstract
Functioning paraganglioma is extra-adrenal catecholamine-secreting tumours that may cause secondary hypertension. Primary intrapericardial paragangliomas are very rare and are located adjacent to the great vessels or heart, typically near the left atrium. These tumours are an exceptionally uncommon finding during the investigation of refractory hypertension. However, in recent years, intrapericardial paragangliomas have been diagnosed incidentally with increased frequency, due to the extensive use of radiologic chest imaging. The mainstay of treatment of functioning intrapericardial paraganglioma is surgical removal, which usually achieves blood pressure normalization. Due to the locations of these tumours, the surgical approach is through a median sternotomy or posterolateral thoracotomy, and manipulation-induced catecholamine release may cause paroxysmal hypertension. Typically in these patients, blood pressure fluctuates dramatically intra- and post-operatively, increasing the risk of cardiovascular complications. We review here the current modalities of perioperative fluid and hypotensive drug administration in the setting of surgery for functioning intrapericardial paraganglioma and discuss the recently proposed paradigm shift that omits preoperative preparation.
