Abstract
The healthcare-associated infections (HAIs) and pandemics caused by multidrug-resistant (MDR) and new-generation pathogens threaten the whole world community. Cu and its alloys have been attracting widespread interest as anti-contamination materials due to the rapid inactivation of MDR-superbugs and viruses. Applying thin Cu-based foils on pre-existing surfaces in hygiene-sensitive areas represents a quick, simple, cost-effective self-sanitising practice. However, the influence of chemical composition and microstructure should be deeply investigated when evaluating the antimicrobial capability and durability of Cu-based materials. The effect of composition on micromechanical and antiviral properties was investigated by comparing Cu15Zn and Cu18Ni20Zn (foil thickness from 13 to 27 μm) with Phosphorous High-Conductivity (PHC) Cu. The influence of recrystallisation annealing of PHC Cu was also investigated. Microstructural characterisation was carried out by optical (OM) and scanning electron (FEG-SEM) microscopy, Energy-dispersive Spectroscopy (EDS) and Electron-Backscattered Diffraction (EBSD). The micromechanical behaviour was assessed by microhardness, microscale abrasion and scratch tests. Cu-based foils were exposed to SARS-CoV-2 for different time points in quasi-dry conditions (artificial sweat solution), evaluating their antiviral capability by quantitative Reverse-Transcriptase Polymerase Chain Reaction (qRT-PCR). Surface morphology, contact angle measurements and Cu release were measured. All Cu-based surfaces completely inactivated SARS-CoV-2 in 10 min: pure Cu was the best option regarding antiviral efficiency, while Cu15Zn showed the best trade-off between micromechanical and antiviral properties.

Abstract
BackgroundLocal and systemic reactions have been observed after all vaccines for SARS-CoV-2 but in the majority of cases, symptoms are mild and self-limiting. However, evidence on more severe clinical scenarios, requiring admission to hospital or referral to outpatient clinics after the administration of SARS-CoV-2 vaccines has accrued. This also includes newly diagnosed diseases, such as cardiovascular and immune-mediated inflammatory diseases (IMID).ObjectivesWe aimed at quantifying the burden of post-vaccine hospital admissions/referrals and of newly diagnosed IMID.MethodsClinical records of patients referred to our Internal Medicine institution (both inpatients and outpatients) between February and June 2021 were retrospectively assessed. Subjects having received one or more doses of any of the EMA-approved SARS-CoV-2 vaccines within the previous 30 days were included. Subjects with a previous diagnosis of IMID were excluded.ResultsOur cohort included 99 patients, 45 females and 54 males, with a mean age of 64 years and a median of 3 comorbities (range 0-7). Eighty-eight patients (89%) required admission to the Internal Medicine ward while 11 were referred to the outpatient clinic. 68 (69%) of patients received the vaccine BNT162b2, 16 (16%) the ChAdOx1 nCoV-19, 9 (9%) the mRNA-1273 and 6 (6%) the Ad26.COV2.S. Twenty-seven (27%) subjects developed symptoms after the first vaccine dose with a mean latency of 2 days (median=0 indicating symptom onset on the day of the vaccine administration). Twenty-four (24%) subjects developed symptoms after the second dose with a mean latency of 4 days (median 1 day). All the other subjects did not develop symptoms within the week after the vaccine and were admitted for reasons apparently unrelated to vaccine administration. The number of presenting complaints ranged between 1 and 4 with 87% of subjects presenting with 1 or two coexisting complaints. Gastrointestinal manifestations were the most frequent being the presenting complaint in 31 (31%) of patients followed by severe fatigue/appetite loss in 19 (19%) of subjects, fever in 18 (18.2%) and neurological manifestation in 16 (16%) of subjects. A temporal and causal association with the SARS-CoV-2 vaccine was identified since all other known causes for these manifestations were ruled out. No in-hospital deaths were observed and 19 (19%) patients were diagnosed with a new onset IMID (Table 1). The clinical picture of these subjects was not significantly different from that of patients without a confirmed IMID and neither were demographic features. No association with the type of vaccine was observed.Table 1.Immune-mediated inflammatory diseases diagnosed after SARS-CoV2 vaccination (N=19)DiseaseNumber of patientsRheumatoid arthritis5Psoriatic arthritis2IgA vasculitis2Spondyloarthritis1Giant cell arteritis1Polymyalgia rheumatica1Gout1Primary biliary cholangitis1Antiphospholipid syndrome1Graves’ disease1Ulcerative colitis1Autoimmune thrombocytopenia1Leukocytoclastic vasculitis1ConclusionOur data show that post-vaccine newly diagnosed IMID may represent a challenge in clinical practice and it seems that no demographic or clinical feature is able to predict their onset. A multidisciplinary cooperation and registry data are needed in order to reliably estimate and define the impact of SARS-CoV-2 vaccinations on new onset IMID.Disclosure of InterestsNone declared

Abstract
BackgroundDespite being commonly expressed in the general population, the human leucocyte antigen (HLA)-B27 allele strongly increases the susceptibility to develop spondyloarthritis (SpA). Likewise, the association between the HLA-B51 allele and the development of Behçet’s disease is well documented. In a previous pilot study, we identified similarities and differences in patients with axial or peripheral SpA according to the presence of HLA-B51 only, HLA-B27 only or neither of the two.ObjectivesTo investigate the clinical and imaging findings of SpA patients according to the absence or presence of HLA-B27 or HLA-B51 in an independent validation cohort.MethodsWe retrospectively analyzed patients with axial or peripheral SpA, according to the ASAS criteria, referring to our institution between 2020 and 2021. All patients had been tested for HLA-B alleles. Patients with HLA-B51 haplotype and fulfilling the criteria for Behçet’s disease were excluded.ResultsThe independent validation cohort included 185 patients and was comparable to the original cohort of 236 patients with regard to age, gender, age at diagnosis and symptom duration. In line with the findings in the original cohort we observed that aphtous lesions were more prevalent in patients with HLA-B51 (p< 0.001) while inflammatory bowel disease was more prevalent in the double negative group (p=0.0006). Unlike the original cohort, patients of the validation cohort did not show a different prevalence of inflammatory back pain (IBP) at disease onset or in the disease course based on the HLA status. A sub-analysis by gender demonstrated a comparable prevalence of IBP in males and females within the 3 groups. As novel finding, we observed that enthesitis and psoriasis were significantly more prevalent in the double negative group compared to the B27 and B51 groups (p=0.004) and their prevalence did not differ when comparing B27 and B51 groups. With regard to imaging in patients with axial manifestations, in the original cohort we observed that sacroiliitis, assessed by X-ray or magnetic resonance imaging (MRI), were more prevalent in double negative and HLA-B27 patients, compared to HLA-B51 patients and the latter showed a significant negative association with sacroiliitis on imaging (OR 0.342 CI 0.189-0.619 p<0.0005). In this validation cohort we observed that the prevalence of sacroiliitis on X-ray was similar in the 3 groups while sacroiliitis on MRI scan was significantly more prevalent in the B27 group (81%) compared to the double negative (63%) and the B51 group (51%). A negative association between sacroiliitis on MRI and HLA-B51 but not double negative status was observed in the validation cohort (OR=0.23, 95% CI=0.07-0.8, p=0.02).ConclusionOur findings underscore the clinical and radiological heterogeneity of patients with SpA and HLA-B51 alone or neither HLA-B27 nor HLA-B51 compared to those with HLA-B27 only and underline the need to explore further this area by means of registry data with large real-life cohorts.Disclosure of InterestsNone declared

Abstract
The new coronavirus emergency spread to Italy when little was known about the infection’s impact on mothers and newborns. This study aims to describe the extent to which clinical practice has protected childbirth physiology and preserved the mother–child bond during the first wave of the pandemic in Italy. A national population-based prospective cohort study was performed enrolling women with confirmed SARS-CoV-2 infection admitted for childbirth to any Italian hospital from 25 February to 31 July 2020. All cases were prospectively notified, and information on peripartum care (mother–newborn separation, skin-to-skin contact, breastfeeding, and rooming-in) and maternal and perinatal outcomes were collected in a structured form and entered in a web-based secure system. The paper describes a cohort of 525 SARS-CoV-2 positive women who gave birth. At hospital admission, 44.8% of the cohort was asymptomatic. At delivery, 51.9% of the mothers had a birth support person in the delivery room; the average caesarean section rate of 33.7% remained stable compared to the national figure. On average, 39.0% of mothers were separated from their newborns at birth, 26.6% practised skin-to-skin, 72.1% roomed in with their babies, and 79.6% of the infants received their mother’s milk. The infants separated and not separated from their SARS-CoV-2 positive mothers both had good outcomes. At the beginning of the pandemic, childbirth raised awareness and concern due to limited available evidence and led to “better safe than sorry” care choices. An improvement of the peripartum care indicators was observed over time.

Abstract
Abstract
Background
The imbalance between protective and harmful bacteria in the microbial communities leads to a non-physiological condition, known as “dysbiosis”. In the last decade, several studies have suggested that gut microbiota can contribute to the development and progression of various disease including cardiovascular disease through metabolism-mediated pathways. The production and the release of bacterial metabolites, including Trimethylamine N-oxide (TMAO), can affect host health acting to distant organs.
Purpose
The aim of the present study was to explore the gut microbiota and the levels of TMAO in patients with stable angina (SA) and acute coronary syndrome (ACS) with or without elevation of the ST segment, respectively STEMI and NSTEMI, and in control subjects.
Methods
Feces were obtained from ACS (n=31) and SA (n=23) patients and controls (n=24). Genomic DNA was isolated using the QIamp DNA Stool Mini Kit. Samples were subjected to 16S rRNA gene V3–V4 region sequencing by an Illumina MiSeq TM platform. A combination of software packages QIIME and VSEARCH was used to generate a biological observation matrix (BIOM) at different taxonomic levels (from phylum to genus). The BIOM was analysed using the Web-based program MicrobiomeAnalyst. β-diversity between groups was obtained by weighted UniFrac distance metric analysis. Serum TMAO levels were measured with a UPLC-MS/MS mass spectrometry in SA and ACS patients.
Results
β-diversity analysis showed a different bacterial composition in SA and ACS patients and controls ([PERMANOVA] F-value: 1.9706; R-squared: 0.050567; p-value <0.018) (Figure 1A). In particular, analysis between the three groups revealed a significant enrichment of Streptococcus genus in ACS patients (Kruskas Wallis test; p=0.0085) (Figure 1B). Controls and ACS revealed a similar gut microbial composition ([PERMANOVA] F-value: 0.7591; R-squared: 0.014388; p-value <0.61) (Figure 2A); in contrast, controls and SA showed separate clusters according to relative differences in taxonomic composition ([PERMANOVA] F-value: 3.0498; R-squared: 0.064821 p-value <0.006) (Figure 2B). Finally, β-diversity analysis in SA and ACS revealed different microbial communities in the two groups [PERMANOVA] F-value: 2.5103; R-squared: 0.046051; p-value <0.025) (Figure 2C) that could partially explain the severity progression of cardiovascular disease. Serum TMAO levels were higher in STEMI (n=14) as compared to SA and to NSTEMI (n=16) (respectively p=0.016 and p=0.028) (Figure 3).
Conclusion
These results, taken together, suggest that gut microbiota and its derived metabolites might play an essential role in the progression of atherosclerosis and in coronary plaque instability.

Abstract
OBJECTIVE The sources of iliac crest bone grafts are limited. Alternatives are evaluated due to the progress in biomaterial sciences. Synthetical hydroxyapatite (HA), ß-tricalcium phosphate (ß-TCP) or biphasic compounds, or even a mélange of HA and ß-TCP will replace bovine ceramics. The goal is maintenance of replica-based-bone formation (RBBF) for bone augmentation. METHODS 2 female and 2 male patients between 41 and 73 years with 5 sinus elevations were evaluated. Sinus elevations with lateral fenestration, trapezoidal-muco-periosteal flaps and filling with micro-chambered beads (1.5 mm) was performed. A porcine-collagenous membrane and the refixated flap covered the defect. A biopsy program over 20 months was confirm confirm the maintenance of the newly formed bone. RESULTS A fast bone formation was pronounced. The biopsies revealed mature lamellar bone and full osseointegration of the ß-TCP implant. The biopsy after 20 months showed compact bone with osseointegration of minor rests of the ceramic implant. The defect revealed a mature bone stock already after 5 weeks. SIGNIFICANCE The introduction of the replica-based-bone formation (RBBF) around micro-chambered beads will change the paradigm of bone augmentation. The next step of the ongoing study has to redefine the interval for implant insertion. The clinical approach confirms the breakthrough to primary mature lamellar bone formation and will permit reduction of placement time for a dental implant.

In the last years, many health apps have been developed to support citizens' and patients' health management. Nevertheless, a thorough evaluation is necessary to support the decision to incorporate them into healthcare systems. Health technology assessment (HTA) could be considered a valid evaluation tool allowing considering different stakeholders' perspectives. This research aimed to look for studies that applied HTA to health apps and to analyze feasibility and limits of HTA in this field.
Methods
A systematic review was performed considering three databases, namely PubMed, Web of Science (WoS) and University of York-Centre for Reviews and Dissemination database. Being the topic of health app assessment new, articles were considered eligible if they assessed at least two of the domains of the HTA core model suggested by the European network for Health Technology Assessment (EUnetHTA). Furthermore, only articles published in English in the last 5 years were considered.
Results
A total of 850 articles were found: 383 articles from PubMed, 462 from WoS and 5 from York. After removing duplicates, 708 articles remained and 43 were eventually included after the screening process. Seven articles were focused on apps used by healthcare professionals, while 36 dealt with apps aimed to support patients. None of the papers explicitly mentioned HTA as assessment tool. Indeed, not all the domains of the HTA core model were assessed in any article. Apps' technical description, clinical effectiveness and social aspects were the domains considered more often. On the contrary, costs and economic evaluation was clearly faced by one article only.
Conclusions
Even though the scientific literature on health apps is growing, the adoption of standardized methods for their evaluation, such as HTA, is still scant. This might be due to peculiarities of health apps and points out the importance of adapting existing methods in order to let a thorough assessment possible.

Abstract
Infections caused by Enterococcus spp. are a major concern in the clinical setting. In Enterococcus faecalis, the capsular polysaccharide diheteroglycan (DHG), composed of ß-d-galactofuranose-(1 → 3)-ß-d-glucopyranose repeats, has been described as an important virulence factor and as a potential vaccine candidate against encapsulated strains. Synthetic structures emulating immunogenic polysaccharides present many advantages over native polysaccharides for vaccine development. In this work, we described the synthesis of a library of DHG oligomers, differing in length and order of the monosaccharide constituents. Using suitably protected thioglycoside building blocks, oligosaccharides up to 8-mer in length built up from either Galf-Glcp or Glcp-Galf dimers were generated, and we evaluated their immunoreactivity with antibodies raised against DHG. After the screening, we selected two octasaccharides, having either a galactofuranose or glucopyranose terminus, which were conjugated to a carrier protein for the production of polyclonal antibodies. The resulting antibodies were specific toward the synthetic structures and mediated in vitro opsonophagocytic killing of different encapsulated E. feacalis strains. The evaluated oligosaccharides are the first synthetic structures described to elicit antibodies that target encapsulated E. faecalis strains and are, therefore, promising candidates for the development of a well-defined enterococcal glycoconjugate vaccine.

Abstract
BACKGROUND Driving is a complex activity that requires a wide range of cognitive, behavioral, sensory and motor competences that are often impaired in cases of severe acquired brain injury (sABI). A safe return to driving is an objective significantly correlated with recovery of personal independence and social-occupational role. AIM The study investigated elements predictive of the possibility of a safe return to driving after sABI, concentrating on motor disability and the need to prescribe vehicle assistive devices. DESIGN Retrospective study. SETTING Out-patients of a rehabilitation center for sABI. POPULATION A series of 217 patients with stable sABI, well reintegrated at family and social level, were enrolled between January 2006 and June 2019. METHODS The subjects were assessed for residual competences. Those who passed assessment of cognitive-behavioral and visual impairment were assessed for motor disability and the need for vehicle assistive devices to enable a safe return to driving. RESULTS About 79% of the population were judged suitable for a return to driving. More than 50% of the latter were only able to return to driving with the aid of vehicle assistive devices. Etiological and demographic variables were not predictive of assessment outcome, whereas the various Griffith motor disability categories were correlated with need for vehicle assistive devices, which are most needed in non-traumatic subjects. CONCLUSIONS Although the literature on return to driving after brain injury focuses mainly on cognitive-behavioral impairment, in a significant percentage of cases it is also necessary to carefully analyse and manage motor disabilities that may result from sABI. CLINICAL REHABILITATION IMPACT Evaluation of the competences necessary for a return to driving after sABI requires a multiprofessional team that must also assess motor disability and know the possible vehicle assistive devices that can enable most candidates to overcome the limits imposed by their disability.

Abstract
Enterococci have emerged as important nosocomial pathogens due to their resistance to the most commonly used antibiotics. Alternative treatments or prevention options are aimed at polysaccharides and surface-related proteins that play important roles in pathogenesis. Previously, we have shown that 2 Enterococcus faecium proteins, the secreted antigen A and the peptidyl-prolyl cis-trans isomerase, as well as the Enterococcus faecalis polysaccharide diheteroglycan, are able to induce opsonic and cross-protective antibodies. Here, we evaluate the use of glycoconjugates consisting of these proteins and an enterococcal polysaccharide to develop a vaccine with broader strain coverage. Diheteroglycan was conjugated to these 2 enterococcal proteins. Rabbit sera raised against these glycoconjugates showed Immunoglobulin G titers against the corresponding conjugate, as well as against the respective protein and carbohydrate antigens. Effective opsonophagocytic killing for the 2 sera was observed against different E. faecalis and E. faecium strains. Enzyme-linked immunosorbent assays against whole bacterial cells showed immune recognition of 22 enterococcal strains by the sera. Moreover, the sera conferred protection against E. faecalis and E. faecium strains in a mouse infection model. Our results suggest that these glycoconjugates are promising candidates for vaccine formulations with a broader coverage against these nosocomial pathogens and that the evaluated proteins are potential carrier proteins.

Abstract
OBJECTIVES From December 2019, a novel coronavirus disease named COVID-19 was reported in China. Within 3 months, the World Health Organization defined COVID-19 as a pandemic, with more than 370,000 cases and 16,000 deaths worldwide. In consideration of the crucial role of diagnostic testing during COVID-19, the aim of this technical note was to provide a complete synthesis of approaches implemented for the management of suspected or confirmed COVID-19 patients. KEY FINDINGS The planning of a robust plan to prevent the transmission of the virus to patients and department staff members should be fundamental in each radiology service. Moreover, the speed of spread and the incidence of the pandemic make it necessary to optimize the use of personal protective devices and dedicated COVID-19 equipment, given the limited availability of supplies. CONCLUSION In the management of radiographic and CT imaging, staff should take special precautions to limit contamination between patients and other patients or professionals. IMPLICATIONS FOR PRACTICE An isolated imaging room should be dedicated to suspected or confirmed COVID-19 cases, including radiography and CT scanners. This paper will provide guidance concerning disposable protective gear to be utilized, as well as on the cleaning and sanitation of radiology room and equipment.

Background
Peri-coronary fat attenuation index (pFAI) has emerged as a clinical marker of coronary
inflammation, which is measurable from standard coronary CT angiography (CCTA). It compares
well with gold-standard methods for the assessment of coronary inflammation and can predict future
cardiovascular events. pFAI could prove invaluable to differentiate an inflammatory from noninflammatory coronary artery status, helping unravel the mechanisms subtending an event classified as myocardial infarction with nonobstructive coronary arteries (MINOCA) or Tako-Tsubo syndrome (TTs).
Methods and Results
Patients admitted with MINOCA and TTs diagnosis between 2011 and 2018,
who had both CCTA and CMR performed during or shortly after the acute phase, were selected and
pFAI measured in their index CCTA. pFAI was also measured in a control subjects who had CCTA
for atypical chest pain work-up, no obstructive coronary artery disease found in their CCTA and no
cardiac events at a minimum 2-year follow-up.
In the n = 106 MINOCA/TTs patients selected, mean pFAI averaged for the 3 coronary arteries was -68.37 ± 8.29 vs -78.03 ± 6.20 in the n = 106 controls (p < 0.0001) and the statistical difference was
confirmed also when comparing mean pFAI in each single coronary artery between MINOCA/TTs
and controls (p < 0.0001). Non-obstructive coronary plaques at CCTA, and high-risk plaques in
particular, were also more frequently found (p < 0.01) in the MINOCA/TTs group compared with
controls.
Conclusions
In MINOCA and TTs patients, CCTA is not only able to detect otherwise angiographically invisible atherosclerotic plaques, but its diagnostic yield can be further expanded using the simple off-line measurement of pFAI for the characterization of peri-coronary fat tissue. In MINOCA/TTs mean pFAI clearly demonstrates higher values in comparison with controls, a finding which has been previously associated with coronary artery inflammation. We speculate that this newly-available diagnostic tool in the future may help select patients for new therapies, for example therapies targeting coronary inflammation.

Abstract
OBJECTIVE To investigate the effectiveness, feasibility, and safety of an evidence-based rehabilitation care pathway in the intensive care unit (ICU) in different patient populations. DESIGN Observational prospective cohort study, with retrospective controls. SETTING ICUs of a university hospital. PARTICIPANTS Patients admitted between April 1, 2015, and June 30, 2015, were compared to a retrospective cohort admitted to the same ICUs during the same 3-month period in 2014. The number of patients studied (N=285) included 152 in the prospective group and 133 in the retrospective group. INTERVENTIONS The prospective cohort benefited of a rehabilitation care pathway based on (1) interdisciplinary teamwork; (2) early customized and goal-oriented rehabilitation; (3) daily functional monitoring and treatment revision; (4) agreed discharge policy; and (5) continuity of care. The retrospective cohort underwent usual care. MAIN OUTCOME MEASURES Included the following: (1) proportions of patients undergoing rehabilitation team evaluation; (2) latency between patient admission to ICUs and rehabilitation team assessment; (3) proportions of patients undergoing rehabilitation treatment during ICU stay; (4) latency between the patient admission to ICUs and rehabilitation start; (5) ICU stay and total acute hospital stay; and (5) proportion of ventilator-free days out of ICU stay. RESULTS The novel rehabilitation care pathway led to (1) an increased proportion of patients receiving rehabilitative assessment (P<.0001); (2) a decreased latency from ICU admission to both rehabilitation team assessment and rehabilitation start (P<.0001); (3) an increased proportion of patients undergoing rehabilitation (P<.0001); (4) a shorter length of stay in ICUs (P<.0001) and in hospital (P=.047); and (5) a shorter mechanical ventilation duration (P<.02). A direct relationship between rehabilitation start latency and ICU length of stay was observed. CONCLUSIONS An early, interdisciplinary team approach, providing a customized dynamic planning of physiotherapy programs, increases ventilator-free time and reduces total hospital stay, especially in patients admitted to the ICU after general surgery. This rehabilitation care pathway can be generalized to different geopolitical scenarios, being feasible, safe and cost effective.

Abstract
In this article the authors propose a specific myofunctional therapy protocol for children with Down syndrome. For these patients, who usually present with atypical swallowing problems, mouth breathing and lip incompetence, the use of a myofunctional therapy protocol with specific exercises has been shown to improve orofacial and nasal functions. In addition to the functional results, such as the correction of the atypical swallowing, restoration of lip competence, breathing improvement and reduction of nasal rhinorrhea, there were also aesthetic results. This protocol can be useful to improve the quality of life of these patients.

Abstract
PURPOSE Pegvisomant (PEGV) treatment in acromegaly patients resistant to somatostatin analogues is less effective in the real life than in clinical trials. This is a multicenter, observational, retrospective, longitudinal study. The aim was to detect characteristics which improve long-term PEGV effectiveness. METHODS 87 acromegalic patients treated with PEGV have been enrolled in seven referral Italian centres. PEGV was administered for up to 4 years, at doses up titrated until IGF-1 normalization or to ≥ 30 mg/day. The rate of patients who reached IGF-1 normalization at last visit has been calculated. RESULTS IGF-1 was normalized in 75.9% of patients after 1 year and in 89.6% at last visit. Disease control was associated with lower baseline GH, IGF-1 and IGF-1 xULN and was more frequent when baseline IGF-1 was < 2.7 × ULN (p < 0.02). PEGV dose was dependent on baseline IGF-1 > 2.7 × ULN (p < 0.05) and doses > 1.0 mg/BMI/day were administered more frequently when baseline IGF-1 was > 2.0 × ULN (p = 0.03). PEGV resistance was associated with higher BMI (p = 0.006) and was more frequent when BMI was > 30 kg/m2 (p = 0.07). There were no significant differences between patients treated with monotherapy or combined treatment. IGF-1 normalization, PEGV dose and rate of associated treatment were similar between males and females. PEGV effectiveness was independent from previous management. Diabetic patients needed higher doses of PEGV than non-diabetic ones. CONCLUSIONS PEGV effectiveness improves when up titration is appropriate. Higher PEGV doses at start and a more rapid up-titration are necessary in patients with obesity and/or IGF-1 > 2.7 × ULN.

Abstract
According to the data of the literature, the prevalence of pain in cancer patients at various stages of the disease and the settings of care range from 38 to 51%, with an increase of up to 74% in the advanced and terminal stages. Despite published World Health Organization (WHO) guidelines for pain management, 42 to 51% of cancer patients receive inadequate analgesia and 30% receive no analgesics at all. A 3-year Research Project “Towards a Pain-free Hospital”, which began one year ago, is ongoing at the National Cancer Institute of Milan. The research is organized in three subsequent steps. In the 1st one, a series of patient- and staff-oriented evaluation tools are used to assess the level of appropriateness of pain communication, assessment, management and control of the in-patients. The 2nd step will implement a number of continuing educational interventions aimed at improving patient awareness and staff knowledge of the appropriate pain assessment and management in order to respond to the patient's pain problem. In the 3rd step, all the assessment tools used in step one will be applied again to establish the prevalence of pain, the causes and intensity and patient satisfaction with pain management and to evaluate the impact of the interventions performed during the 2nd step regarding the overall ability of our hospital to tackle pain emergency in the hospitalized cancer population. The results relative to the 1st step are herein reported, in particular as regards the study on prevalence, causes, severity of pain, the interference of pain with sleep, mood and concentration, the use of pain medications and the relief obtained, the structural validity and internal consistency of the assessment tool used. A total of 258 patients hospitalized for at least 24 h were interviewed by 9 physicians using a brief structured questionnaire prepared ad hoc: 51.5% of the patients presented pain during the previous 24 h caused by surgery (49.6%) or by the tumor mass itself (29.3%). Out of the 133 patients with pain, a high degree (much or very much) of pain at rest was present in 27.1% and pain on movement in 30.8%; 31.6% did not take any analgesic treatment, and 14.3% of the latter reported a high degree of pain at rest and 21.4% on movement. Pain interfered with sleep from much to very much in 28.8% and with irritability and nervousness in 15.9% of the patients. In the 91 patients taking analgesics, 57.2% reported a high degree of pain relief. A high degree of pain and interference, however, was associated with low relief levels. The assessment tool used was shown to have a good structural validity and internal consistency (Chrombach alpha index of interference scale = 0.73). Although the Milan Cancer Institute has the longest tradition in Italy of pain assessment by means of validated tools and pain management according to the WHO guidelines and educational efforts in this field, the results of the study clearly show that it is necessary to persevere with continuing educational and informative programs in order to reduce the frequency and severity of pain and thus improve the quality of life of in-patients.

Abstract
PURPOSE The aim of this study is to investigate guideline application and colonoscopy findings in real-life practice in acromegaly. METHODS We conducted a retrospective observational non-interventional and cross-sectional analysis on 146 patients with acromegaly (ACRO) referred to our clinic. We evaluated colonoscopy data, focusing on the correlation between colonoscopy findings and hormonal/metabolic values. RESULTS The total number of colonoscopies performed in ACRO patients increased from 6 in the period 1990-1994 to 57 in the period 2010-2014. Colonoscopy procedures were performed according to guidelines in 25% of ACRO patients at diagnosis, 51% at follow-up and 11% globally (both at diagnosis and follow-up). Among the 146 ACRO patients, 68% were subjected to at least one colonoscopy and in 32% of the cases a polyp was detected during the procedure. The presence of polyps was significantly associated with mean levels of growth hormone (GH), insulin-like growth factor 1 (IGF-1), fasting glucose and insulin levels (p < 0.05). Polyps were detected in 48% of untreated patients and in 26% of patients under treatment for acromegaly (p = 0.04). The general risk of polyps and adenomatous polyps in ACRO patients was higher compared to the control population of Veneto Region, Italy (odds ratio 1.33 and 1.16, respectively). No cancerous polyps were detected in our analysis. CONCLUSION In real-life practice, adherence to ACRO colonoscopy clinical guidelines was lower than expected. Among patients who underwent colonoscopy, the prevalence of colon polyps was higher for ACRO patients, suggesting the need for new strategies to ensure adherence to colonoscopy guidelines.

Abstract
Exercise may exert beneficial effects on cognitive functions and play an important role in the prevention of neurodegenerative diseases. Such effects seem to be mediated by changes in anti-oxidative status, but limited information is available on the nature of molecular pathways supporting the antioxidant effects of exercise in the brain. In this study 3-5-month-old male Wistar albino rats were subjected to three times/week moderate intensity exercise on a rodent treadmill for a period of 6 weeks. The tissue antioxidant activity towards various reactive oxygen species (ROS) was determined in the hippocampus. In addition, to identify the molecular pathways that may be involved in ROS metabolism, the expression of nerve growth factor (NGF) and sirtuins (SIRT1 and SIRT3) were measured. Our results showed a higher antioxidant activity in the hippocampus of physically trained rats compared to sedentary controls. Furthermore, exercise induced an up-regulation of NGF, possibly related to an improved redox balance in the hippocampus. These results suggest that physical exercise might prevent age-induced oxidative damage in the hippocampus.

Abstract
Today, liposomes are an advanced technology of drug carriers with a dozen drugs in clinical practice and many more in clinical trials. A bottleneck associated with the clinical translation of liposomes has long been 'opsonization', i.e. the adsorption of plasma proteins at the liposome surface resulting in their rapid clearance from circulation. For decades, the most popular way to avoid opsonization has been grafting polyethylene glycol (PEG) onto the liposome surface. Recent studies have clarified that grafting PEG onto the liposome surface reduces, but does not completely prevent protein binding. In this work, we employed dynamic light scattering, zeta-potential analysis, one-dimensional sodium dodecyl sulfate polyacrylamide gel electrophoresis (1D-SDS-PAGE), semi-quantitative densitometry and cell imaging to explore the bio-nano-interactions between human plasma (HP) and Onivyde, a PEGylated liposomal drug that has recently been approved by the Food and Drug Administration (FDA) for the treatment of metastatic pancreatic ductal adenocarcinoma (PDAC). To properly evaluate the role of PEGylation, an unPEGylated variant of Onivyde was used as a reference. Collectively, our findings suggest that: (i) although PEGylated, Onivyde is not "stealth" in HP; (ii) surface chemistry is more important than PEGylation in controlling the bio-nano-interactions between Onivyde and plasma components. Of note is that the PC was found to boost the cellular uptake of Onivyde in the pancreas ductal adenocarcinoma cell line (PANC-1) thus suggesting its prominent role in its indication for PDAC treatment. Relevant implications for drug delivery and drug design are discussed.

Abstract
Angiogenin is a member of the ribonuclease family and a normal constituent of human plasma. It is one of the most potent angiogenic factors known and is overexpressed in different types of cancers. Copper is also an essential cofactor in angiogenesis and, during this process, it is mobilized from inside to outside of the cell. To date, contrasting results have been reported about copper(ii) influencing angiogenin activity. However, in these studies, the recombinant form of the protein was used. Unlike recombinant angiogenin, that contains an extra methionine with a free terminal amino group, the naturally occurring protein present in human plasma starts with a glutamine residue that spontaneously cyclizes to pyroglutamate, a lactam derivative. Herein, we report spectroscopic evidence indicating that copper(ii) experiences different coordination environments in the two protein isoforms, and affects their RNase and angiogenic activity differently. These results show how relatively small differences between recombinant and wild type proteins can result in markedly different behaviours.

Abstract
BACKGROUND Although deep neuromuscular block (post-tetanic-count 1-2 twitches) improves surgical conditions during laparoscopic retroperitoneal surgery compared with standard block (train-of-four 1-2 twitches), the quality of surgical conditions varies widely, often related to diaphragmatic contractions. Hypocapnia may improve surgical conditions. Therefore we studied the effect of changes in arterial carbon dioxide concentrations on surgical conditions in patients undergoing laparoscopic surgery under general anaesthesia and deep neuromuscular block. METHODS Forty patients undergoing elective laparoscopic surgery for prostatectomy or nephrectomy received propofol/remifentanil anaesthesia and deep neuromuscular block with rocuronium. Patients were randomized to surgery under hypocapnic or hypercapnic conditions. During surgery, the surgical conditions were evaluated using the 5-point Leiden-Surgical Rating Scale (L-SRS) ranging from 1 (extremely poor conditions) to 5 (optimal conditions) by the surgeon, who was blinded to group. RESULTS Mean (sd) arterial carbon dioxide concentrations were 4.5 (0.6) [range: 3.8-5.6] kPa under hypocapnic and 6.9 (0.6) [6.1-8.1] kPa under hypercapnic conditions. The L-SRS did not differ between groups: 4.84 (0.4) [4-5] in hypocapnia and 4.77 (0.4) [3.9-5] in hypercapnia. Ninety-nine percent of ratings were good or excellent irrespective of treatment. CONCLUSIONS Deep neuromuscular block provides good to optimal surgical conditions in laparoscopic retroperitoneal urological surgery, independent of the level of arterial [Formula: see text].

Abstract
Oxidative stress plays critical roles in the pathogenesis of diabetes, hypertension, and atherosclerosis; some authors reported that fat accumulation correlates to systemic oxidative stress in human and mice, but cellular redox environment effect on lipid accumulation is still unclear. In our laboratory we used mouse embryonic fibroblasts (undifferentiated cells: CC), which are capable of differentiating into mature adipocytes (differentiated cells: DC) and accumulate lipids, as obesity model. Here we analyzed the role of the well-known antioxidant and glutathione precursor N-acetylcysteine (NAC) in cellular MAPK modulation and lipid accumulation. We evaluated the effect of NAC on the adipogenic differentiation pathway using different doses: 0.01, 0.1, 1 and 5 mM; no toxic doses in these cells. A dose of 5 mM NAC [DCN-5] provoked a significant decrease in triglyceride accumulation (72±10 [DCN-5] vs 169±15 [DC], p<0.01), as well in Oil Red O stained neutral lipid content (120±2 [DCN-5] vs 139±12 [DC], p<0.01). Molecular mechanisms responsible for adipogenic differentiation involve increase of the expression of phosphoERK½ and phosphoJNK, 5 mM NAC treatment inhibited both pERK½ and pJNK protein levels. We also evaluated the mitotic clonal expansion (MCE) which takes place during adipogenesis and observed an increase in DC at a rate of 1.5 cells number compared to CC at day 2, whereas the highest doses of NAC significantly inhibited MCE. Our results suggest that NAC inhibits lipid accumulation and the MAPK phosphorylation in mouse embryonic fibroblasts during adipogenic differentiation and further contribute to probe the importance of cellular redox environment in adipogenesis. NAC, up to 5 mM, is not toxic in adipocytes obtained from mouse embryonic fibroblasts. NAC inhibited phosphorylation of ERK½ and JNK in adipogenic differentiation. NAC inhibited mitotic clonal expansion in adipogenic differentiation. NAC inhibited triglyceride and lipid accumulation in mouse embryonic adipocytes.

Abstract
Abstract
Background: Genetic counselling and testing (GCT) for hereditary breast and ovarian cancer (BOC) has become a standard option in BOC care in Europe allowing for prognostic information on the individual risk for disease onset/ relapse as well as on treatment options comprising prophylactic surgery or surveillance programs. However, data on the psychosocial long-term consequences is limited, especially in high-risk counsellees opting against genetic testing. We aimed at investigating the long-term psychosocial consequences of GCT for hereditary BOC in all counsellees irrespective of their decision after counselling.
Patients and Methods: Counsellees for BOC with and without a previous disease who had undergone genetic counselling at Innsbruck Medical University between 2011 and 2014 were asked to participate in a cross-sectional Patient Reported Outcome (PRO) assessment (incl. Multidimensional Impact of Cancer Risk Assessment, Genetic counseling satisfaction scale, Satisfaction with Decision Scale, Breast Cancer Heredity Knowledge Scale, Hospital Anxiety and Depression Scale/ HADS, Short Form 12 Health Survey, Cancer Worry Scale/ CWS) targeting on psychological distress, cancer worry, patient knowledge and patient satisfaction with genetic counselling and decisions by means of an anonymous mail survey. Subsequent decisions for vs. against genetic testing and if eligible, for surveillance vs. prophylactic surgery were also assessed. A reference sample of BC survivors was recruited at the outpatient unit.
Results: An overall sample of 137 counselees was included in the analysis (67.9% decided to undergo genetic testing for a HCPS, 22.6% decided not to be tested, 9.5% were still uncertain about their decision). 22.6% of counsellees experienced clinically relevant levels of anxiety and 9.8% scored above the cut-off for clinically relevant depression according to the HADS. Mean CWS score was 11 (SD 3.6, 3-24). Counsellees did not differ from breast cancer survivors regarding anxiety and depression according to the HADS (depression: p<0.5). Mean patient satisfaction with decisions amounted to 25.4 (SD 5.78, min. 4 to max. 30); a mean satisfaction with counselling of 25 (5.4) was observed. Less overall satisfaction with genetic counselling (β=0.445, t=5.552, p=0.000) and lower certainty about decision for/ against genetic testing after counselling (β=-0.169, t=-2.105, p=0.037) were highly predictive for lower long-term patient satisfaction with decisions.
Conclusion: Our results indicate that genetic counselling for BOC has no overall deleterious psychosocial consequences in long-term. Levels of depression and anxiety were comparable to those of the general population, while distress levels did not differ from those of breast cancer survivors without a hereditary BOC predisposition. The overall satisfaction with counselling as well as the certainty with decisions on testing and related medical interventions are highly predictive for the long-term satisfaction with decisions. Hence, genetic counselling should focus on supporting counsellees in forming clear decisions and include identifying counsellees with increased cared needs in this regard by means of PRO assessment in follow-up.

Abstract
BACKGROUND Cardiovascular complications, including arrhythmias and cardiac sudden death, are the most common causes of enhanced mortality in acromegaly. However, few data are available on cardiac autonomic functions and sympathovagal balance in acromegalic patients. OBJECTIVE The aim of this study was to investigate both the time and frequency domain parameters of Heart Rate Variability (HRV), in order to characterize the cardiac autonomic functions in patients affected by acromegaly. This study correlated anthropometric, metabolic, echocardiographic parameters and blood pressure with those relating to HRV, to identify the main factors responsible for the HRV related alterations possibly present. We also aimed to analyze the effects of the treatment with somatostatin analogues (SSAs) on HRV. MATERIALS AND METHODS This study enrolled 47 acromegalic patients (23 males, age 49.1 ± 13.5 years) and 37 (13 males) age matched (52.3 ± 13.3 years) healthy subjects. All participants underwent 12-lead 24 h ECG Holter recordings and a HRV analysis of the ECG tracings was performed. The parameters obtained from the time domain analysis of HRV included pNN50, SDNN, SDNN index, SDANN and RMSSD. The power spectral analysis of HRV was obtained by summing powers of the LF (low frequency) and the HF (high frequency) band. Sympathovagal balance was estimated by calculating the LF/HF ratio during 24 h and 15 min of clinostatism. The HRV of 28 acromegalic patients was studied before and after SSAs treatment. RESULTS Acromegalic patients showed significantly lower SDNN and SDANN compared to controls. Diabetic and non-diabetic acromegalic patients showed decreased SDNN and SDANN, when compared to healthy subjects. Diabetic acromegalic patients had a lower LF/HF ratio during 24 h when compared to non-diabetic acromegalic patients. Similar results were obtained analyzing patients affected by acromegaly and impaired glucose tolerance. SDNN and SDANN were lowered by hypertension in the acromegalic population, when compared to controls, and hypertensive acromegalic patients also displayed a decreased LF/HF ratio during 24 h when compared to normotensive acromegalic subjects. Patients with ventricular arrhythmias in Lown classes 3-5 showed a decreased SDANN compared to patients in Lown class 0-2. The treatment with SSAs was able to ameliorate all the time domain parameters of HRV, without altering the 24 h LF/HF ratio. CONCLUSION Cardiac autonomic functions and sympathovagal balance are altered in patients affected by acromegaly and could be ameliorated by SSAs therapy. HRV analysis allows an estimation of the autonomic sympathovagal balance and may be a useful clinical tool for the cardiac risk stratification in acromegalic patients.

Abstract
Therapies that target the signal transduction and biological characteristics of cancer stem cells (CSCs) are innovative strategies that are used in combination with conventional chemotherapy and radiotherapy to effectively reduce the recurrence and significantly improve the treatment of glioblastoma multiforme (GBM). The two main strategies that are currently being exploited to eradicate CSCs are (a) chemotherapeutic regimens that specifically drive CSCs toward cell death and (b) those that promote the differentiation of CSCs, thereby depleting the tumour reservoir. Extracellular purines, particularly adenosine triphosphate, have been implicated in the regulation of CSC formation, but currently, no data on the role of adenosine and its receptors in the biological processes of CSCs are available. In this study, we investigated the role of adenosine receptor (AR) subtypes in the survival and differentiation of CSCs isolated from human GBM cells. Stimulation of A1AR and A2BAR had a prominent anti-proliferative/pro-apoptotic effect on the CSCs. Notably, an A1AR agonist also promoted the differentiation of CSCs toward a glial phenotype. The differential effects of the two AR agonists on the survival and/or differentiation of CSCs may be ascribed to their distinct regulation of the kinetics of ERK/AKT phosphorylation and the expression of hypoxia-inducible factors. Most importantly, the AR agonists sensitised CSCs to the genotoxic activity of temozolomide (TMZ) and prolonged its effects, most likely through different mechanisms, are as follows: (i) by A2BAR potentiating the pro-apoptotic effects of TMZ and (ii) by A1AR driving cells toward a differentiated phenotype that is more sensitive to TMZ. Taken together, the results of this study suggested that the purinergic system is a novel target for a stem cell-oriented therapy that could reduce the recurrence of GBM and improve the survival rate of GBM patients.

Abstract
Monilinia spp. are well-known pathogens causing brown rot of fruit trees in many fruit production areas worldwide. In Italy, three Monilinia species are particularly significant with regard to fruit trees, causing blossom and twig blight and brown rot in fruits: Monilinia laxa (Aderhold and Ruhland) Honey, M. fructicola (Winter) Honey, and M. fructigena (Aderhold and Ruhland). In 2009, a new species, M. polystroma, was distinguished from M. fructigena based on morphological and molecular characteristics in Europe (3). M. polystroma is not known to occur in Italy and to date has been reported from the Czech Republic (1), Hungary (3), Poland (4), Serbia (5), and Switzerland (2). In July 2013, during a survey for fungal postharvest pathogens, stored peaches (Prunus persica (L.) Batsch) belonging to different cultivars showing brown rot symptoms were observed in the Emilia Romagna and Sardinia regions of Italy. Typical decay spots were circular and brown, tending toward black, and 5% of peaches presented a large number of yellowish or buff-colored stromata and firm decayed tissues, the symptoms originated by M. polystroma. The pathogen was isolated on V8 agar (V8A) and culture plates were incubated at 25°C in darkness for 5 days. A conidial suspension was spread on malt extract agar (MEA) and single spores were selected. M. polystroma colonies grown on potato dexstrose agar (PDA) were yellowish in color. Irregular black stromatal crusts occurred on the edges of the colonies after 10 to 12 days of incubation and on the margin was present sporogenous tissue slightly elevated above the colony surface, color buff/pale luteous (1). The conidia were one-celled, ovoid or limoniform, smooth and hyaline, and 12 to 20 × 8 to 12 μm in distilled water when grown on V8A at 22°C. The ribosomal ITS1-5.8S-ITS2 region was PCR-amplified from genomic DNA obtained from mycelium using primers ITS1 and ITS4. A BLAST search in GenBank revealed the highest similarity (99%) to M. polystroma sequences (GenBank Accession No. GU067539). Pathogenicity was confirmed using surface-sterilized mature 'Red Heaven' peaches. The fruits were wounded (2 × 2 × 2 mm) twice with a sterile needle and inoculated with 2-mm plugs of 7-day-old mycelia from fungal colony margins. The sample unit was represented by 10 fruits. Control fruits were inoculated with PDA. After 7 days of incubation at 20°C in plastic containers with high humidity, typical symptoms of brown rot developed on both the wounds of all inoculated fruits, while control fruits remained symptomless. By the 14th day, all fruits had rotted and the yellowish exogenous stromata appeared on the surface of infected peaches. The fungus isolated from inoculated fruit exhibited the same morphological and molecular features of the original isolates; the molecular analysis performed using the primers by Petroczy (3) confirmed the result of the PCR with ITS1 and ITS4 primers. To our knowledge, this is the first report of M. polystroma on peach in Italy. This is relevant because the new pathogen could spread into other European countries that are main peach producers (such as Spain), causing economic losses. Bringing it to the attention of the scientific community allows the arrangement of research studies for assessing potential resistances with a significant impact on disease control management. Further studies are necessary to determine geographic distribution, prevalence, and economic importance of this organism in Italy.

Abstract
CONTEXT Hepatotoxicity is one of the most serious adverse effects in acromegalic patients treated with pegvisomant (PEG-V). Recent studies have found an association between this adverse event and the UGT1A1 allele 28 polymorphism associated with Gilbert's syndrome. OBJECTIVE To determine whether UGT1A1*28 and alcohol dehydrogenase (ADH) polymorphisms influence liver toxicity during PEG-V treatment. DESIGN AND SETTING Multicenter observational retrospective study conducted in 13 tertiary care endocrinology units in Italy. PATIENTS A total of 112 patients with active disease resistant to somatostatin analogs (SSTa) and 108 controls were enrolled. INTERVENTIONS Clinical and biochemical data were recorded by electronic clinical reporting forms. Blood or DNA samples were sent to the coordinating center for genotyping. RESULTS No differences in genotypes between patients and controls were found. During PEG-V therapy liver function tests (LFT), abnormalities and overt hepatotoxicity developed in 17 and 4.5% of patients respectively. Logistic and linear regression analyses showed an association between LFT abnormalities during the follow-up visit and prior events of LFT abnormalities in medical history (odds ratio=1.25; P=0.04) and the number of concomitant medications, other than SSTa (B=3.9; P=0.03). No correlation between LFT alterations and UGT1A1 allele 28 as well as ADH1C and B polymorphisms was found. CONCLUSIONS UGT1A1 allele 28 and ADH1C and B polymorphisms do not predict increased risk of hepatotoxicity during PEG-V therapy. Conversely, patients with multi-therapies and with previous episodes of liver disease should be carefully managed, due to the observed association between these conditions and LFT abnormalities during PEG-V therapy.

Abstract
Monilinia fructicola (G. Wint.) Honey, the causal agent of brown rot, is one of the most important fungal pathogens of stone fruit but may also affect pome fruits. The pathogen is common in North America, Oceania, South America, and Asia. It is a quarantined pathogen in Europe (3), but was recently detected in apple from the Czech Republic, Germany, and Serbia (1,2,4). In January 2012, during a survey for fungal postharvest pathogens, stored apple (Malus domestica Borkh.) belonging to the cultivars Gala and Pink Lady showing brown rot symptoms were observed in the Emilia Romagna region, Italy. Typical decay spots were circular and brown, tending toward black. Decayed tissues remained firm, and numerous grayish pustules containing spores appeared on rotted areas. The pathogen was isolated on V8 juice agar and culture plates were incubated at 25°C in darkness for 5 days. A conidial suspension was spread on malt extract agar and single spores were selected. The colonies were morphologically identified as M. fructigena. Two colonies developing a gray mass of spores in concentric rings with the reverse side black were further studied by molecular tools. The colony margins were even and the conidia were one-celled, limoniform, hyaline, and 12.1 to 17.4 × 8.4 to 11.2 μm. The ribosomal ITS1-5.8S-ITS2 region was PCR-amplified from genomic DNA obtained from mycelium using primers ITS1 and ITS4. A BLAST search in GenBank revealed the highest similarity (99%) to M. fructicola sequences (GenBank Accession Nos. HQ893748.1 and FJ515894.1). Pathogenicity was confirmed using surface-sterilized mature 'Gala' apples, wounded with a sterile needle, and inoculated with an isolate conidial suspension (103 spores/ml). A 20 μl droplet was placed in the wound; control fruits received sterile water without conidia. After 5 days of incubation at 20°C in plastic containers with high humidity, typical symptoms of brown rot developed on inoculated fruits, while control fruits remained symptomless. The fungus isolated from inoculated fruit exhibited the same morphological and molecular features shown by the original isolates. To our knowledge, this is the first report of the fungus M. fructicola on apple in Italy. Further studies are necessary to determine geographic distribution, prevalence and economic importance of this quarantine organism in Italy. References: (1) J. Duchoslavovà et al.

Abstract
BACKGROUND AND PURPOSE Recently, a small molecule (Q94) was reported to selectively block PAR(1) /Gα(q) interaction and signalling. Here, we describe the pharmacological properties of Q94 and two analogues that share its benzimidazole scaffold (Q109, Q89). Q109 presents a modest variation from Q94 in the substituent group at the 2-position, while Q89 has quite different groups at the 1- and 2-positions. EXPERIMENTAL APPROACH Using human microvascular endothelial cells, we examined intracellular Ca(2+) mobilization and inositol 1,4,5-trisphosphate accumulation as well as isoprenaline- or forskolin-stimulated cAMP production in response to thrombin. KEY RESULTS Q89 (10 µM) produced a leftward shift in the thrombin-mediated intracellular Ca(2+) mobilization concentration-response curve while having no effect on the E(max) . Both Q94 (10 µM) and Q109 (10 µM) reduced intracellular Ca(2+) mobilization, leading to a decrease in E(max) and an increase in EC(50) values. Experiments utilizing receptor-specific activating peptides confirmed that Q94 and Q109 were selective for PAR(1) as they did not alter the Ca(2+) response mediated by a PAR(2) activating peptide. Consistent with our Ca(2+) results, micromolar concentrations of either Q94 or Q109 significantly reduced thrombin-induced inositol 1,4,5-trisphosphate production. Neither Q94 nor Q109 diminished the inhibitory effects of thrombin on cAMP production, indicating they inhibit signalling selectively through the G(q) pathway. Our results also suggest the 1,2-disubstituted benzimidazole derivatives act as 'allosteric agonists' of PAR(1) . CONCLUSIONS AND IMPLICATIONS The Q94 and Q109 benzimidazole derivatives represent a novel scaffold for the development of new PAR(1) inhibitors and provide a starting point to develop dual signalling pathway-selective positive/negative modulators of PAR(1) .

Abstract
Thanks to its intrinsic high spatial resolution, ultrasound is an ideal imaging modality for examining very thin, superficial structures, and this makes it very helpful in the evaluation of extrinsic carpal ligaments. These structures, which arise from the radius and ulna and insert on the carpal bones, are extremely important for wrist stability. Previous studies have assessed the use of ultrasound to study the extrinsic carpal ligaments in cadavers, healthy asymptomatic subjects, and patients with rheumatoid arthritis. In the present report, we review the normal anatomy, biomechanics, and ultrasound appearance of these ligaments.

Abstract
The translocator protein (TSPO) is a five transmembrane domain protein localised primarily in the outer mitochondrial membrane of steroid-synthesizing tissues, including the brain. The TSPO mediates the rate-limiting step of steroidogenesis, consisting of the translocation of the substrate cholesterol from the outer to the inner mitochondrial membrane. In the recent years TSPO function has received attention in several psychiatric disorders since these diseases have been associated with unbalanced steroid levels. Accordingly, an alteration in the levels of TSPO has been found in various psychiatric disorders, including social phobia, post-traumatic stress disorder, adult separation anxiety and schizophrenia. The discovery that TSPO drug ligands are able to stimulate neurosteroid production in the brain, independently of peripheral endocrine sources, and restore neurosteroid-mediated neurotransmission, has made the TSPO an attractive drug target for treating a number of psychiatric disorders. In anxiety TSPO drug ligands have shown in vivo efficacy in pharmacologically induced anxiety models in both animals and humans. The focus of this review is to illustrate the currently available literature regarding the role of TSPO in psychiatric disorders.

Abstract
The translocator protein (TSPO) (18 kDa) is an emerging drug target for the treatment of numerous pathologies including cancer and neurodegenerative disease. However, our limited knowledge of TSPO binding site(s) has hindered the development of TSPO ligands with potential therapeutic effects. We have synthesized a series of pyrrolobenzoxazepines (1-10) to better characterize the interaction of ligands with the TSPO across species, and to determine their functional profiles. All ligands 1-10 displaced the binding of [3H]PK 11195 to the TSPO at nanomolar concentrations, with discrepancies in binding affinity between rat and human TSPO. Interestingly, non-linear regression analysis revealed that some ligands bound to the protein with a Hill slope not equal to 1.0, suggesting possible additional TSPO binding sites with allosteric effects. However, this trend was not conserved between rat and human. When tested for their effects on pregnenolone production in rat C6 glioma cells, nitric oxide release in murine microglia, and cell proliferation in human MCF-7 breast cancer cells, the pyrrolobenzoxazepines (40 μM) displayed functional effects which did not correlate to the binding trend observed in competition assays. We propose that consideration of species differences and binding site cooperativity, plus optimization of currently accepted functional assays, will aid in the development of drugs targeting TSPO that can be used as therapeutics for human disease.

Abstract
OBJECTIVE To describe demographic and hormonal characteristics, comorbidities (diabetes mellitus and hypertension), therapeutic procedures and their effectiveness, as well as predictors of morbidity and mortality in a nationwide survey of Italian acromegalic patients. DESIGN Retrospective multicenter epidemiological study endorsed by the Italian Society of Endocrinology and performed in 24 tertiary referral Italian centers. The mean follow-up time was 120 months. RESULTS A total of 1512 patients, 41% male, mean age: 45±13 years, mean GH: 31±37 μg/l, IGF1: 744±318 ng/ml, were included. Diabetes mellitus was reported in 16% of cases and hypertension in 33%. Older age and higher IGF1 levels at diagnosis were significant predictors of diabetes and hypertension. At the last follow-up, 65% of patients had a controlled disease, of whom 55% were off medical therapy. Observed deaths were 61, with a standardized mortality ratio of 1.13 95% (confidence interval (CI): 0.87-1.46). Mortality was significantly higher in the patients with persistently active disease (1.93; 95% CI: 1.34-2.70). Main causes of death were vascular diseases and malignancies with similar prevalence. A multivariate analysis showed that older age, higher GH at the last follow-up, higher IGF1 levels at diagnosis, malignancy, and radiotherapy were independent predictors of mortality. CONCLUSIONS Pretreatment IGF1 levels are important predictors of morbidity and mortality in acromegaly. The full hormonal control of the disease, nowadays reached in the majority of patients with modern management, reduces greatly the disease-related mortality.

Abstract
BACKGROUND AND OBJECTIVES A role for the protein that mediates the rate-limiting step of steroidogenesis, the 18 kDa Translocator Protein (TSPO), has been suggested in the pathophysiology of Adult Separation Anxiety Disorder (ASAD). It has been shown that ASAD patients have 1) low TSPO expression levels and 2) a high frequency of the allele that substitutes Ala with Thr at position 147 of TSPO. The Thr147 ASAD-associated allele has been recently related with a low pregnenolone production. The aim of the present work was to evaluate the relationship between TSPO expression levels and Ala147Thr single nucleotide polymorphism (SNP), which are the two TSPO biological parameters that we have previously examined separately. A further aim was to confirm the genetic association of Ala147Thr SNP with ASAD in an extended case-control sample and to investigate whether this SNP was related to an anxious attachment style that is thought to be connected to ASAD. METHODS TSPO expression levels were compared among patients with ASAD (n=26), without ASAD (n=26) and control samples (n=10) stratified into the two genotype groups: those with the Ala147 genotype (named "normal pregnenolone production") and those with the Thr147 genotype (named "reduced pregnenolone production"). The case-control genetic study included patients with (n=87) or without (n=101) ASAD and 236 controls. In the patient group, the association between the Ala147Thr SNP and an anxious attachment style was analysed by stepwise logistic regression analysis. RESULTS The genotype with the lowest TSPO expression levels was the "normal pregnenolone production" genotype in the ASAD group. The genetic Ala147Thr SNP confirmed an excess of the Thr147 allele in ASAD patients. Stepwise logistic regression analysis did not show an association with an anxious attachment style. CONCLUSIONS ASAD individuals who expressed normal TSPO levels exhibited the "reduced pregnenolone production" genotype. In contrast, the ASAD individuals with the "normal pregnenolone production" genotype expressed low TSPO levels. It is possible that low TSPO expression levels could compromise normal pregnenolone production. Such evidence may have therapeutic implications because it has been documented that drugs targeting TSPO increased pregnenolone production and have anxiolytic effects.
