Abstract
RATIONALE FOR THE STUDY This cross-sectional multicenter study was conducted to investigate any difference in liver stiffness measurements (LSM), evaluated by transient elastography, between patients affected by β thalassaemia major, with and without hepatitis C virus (HCV) infection, and healthy blood donors (controls). Secondary aim was to assess any correlation between transient elastography and serum ferritin, liver magnetic resonance imaging (MRI) T2* or superconductive quantum interference device (SQUID) liver susceptometry values. MATERIALS AND METHODS The study involved three centers. Transient elastography and MRI T2* examinations were performed in all centers. SQUID liver susceptometry was performed in center1 and center2. T-test for independent data or Mann-Whitney U test was used to analyse differences between two groups. Univariate Pearson's r coefficient was used to test correlations between liver stiffness measurements and all other variables. RESULTS In a study with 119 patients and 183 controls, patients who had never been infected with HCV showed significantly higher LSMs than controls [5.7 (95% CI, 5.2-6.2) kPa vs. 4.3 (95% CI, 4.1-4.4) kPa, p < 0.0001]. A moderate correlation between LSMs and ferritin values, adjusted for gender and age, was found in patients (r = 0.49, p < 0.0001) but not in controls (r = -0.22, p = 0.6). No correlation between LSMs and MRI T2* or SQUID liver susceptometry values was observed. In conclusion, compared to controls β thalassaemia major patients had a significant increase in LSMs independently from HCV infection.

Abstract
The purpose of this study is to describe the epidemiological surveillance of microbiological sentinel events (SEs) carried out between 2012 and 2014 at the Neurological Hospital Carlo Besta, Milano, Italy. The setting is inpatient care with multidrug-resistant infections. The aim of the procedure is to formalize the management mode, reporting and transmission of SEs. Categorical variables were described by counts and percentages, as mean and sd or median and interquartile range. The incidence rates of SE were calculated per 1000 patient-days and for 100 admissions using Poisson distribution. The incidence rate of isolation for 1000 patient-days varies from a minimum of 0.52 (95 % confidence interval, 0.23-1.15) for the second quarter of 2014 to a maximum value of 4.16 (95 % confidence interval, 3.20-5.40) for the first quarter of 2013. A decrease followed from the third quarter of 2013 that remained constant in 2014, reaching values similar to those of 2012. Preventive actions and their effectiveness on Acinetobacterbaumannii, the primary cause in our division of multidrug-resistant infections in 2012, have ensured a reduction of the incidence of the same; preventive actions and their effectiveness allowed us to intercept microbiological SE and trigger appropriate precautionary behaviour and isolation. Surveillance of healthcare-associated infections is fundamental in understanding the sources that are contributing to the growing reservoir within hospital communities.

Abstract
BACKGROUND & AIMS Ultrasound is the imaging modality most widely utilized in the general population for diagnostic purposes. Controlled attenuation parameter is a novel noninvasive method for assessing steatosis. Our aim was to investigate whether the clinical value of controlled attenuation parameter in patients referred for abdominal ultrasound examinations is affected by liver fibrosis. METHODS Consecutive patients referred for abdominal ultrasound examinations were enrolled. Controlled attenuation parameter and liver stiffness were assessed with the FibroScan (Echosens, France). Liver fibrosis was staged according to published cutoffs of liver stiffness measurements. Pearson's or Spearman's rank correlation coefficient was used to test the association between two study variables. Optimal cutoff of controlled attenuation parameter for diagnosing liver steatosis (S≥2) was 256 dB/m. The diagnostic performance and accuracy of dichotomized controlled attenuation parameter, ultrasound and body mass index were analysed using the imperfect gold standard methodology. RESULTS A total of 726 subjects (464 males and 262 females) were studied. Five hundred and eight-nine (81.1%) patients were affected by chronic viral hepatitis. Correlation of controlled attenuation parameter with ultrasound score was 0.48 and 0.57 in patients with and without chronic viral hepatitis respectively. In patients with chronic viral hepatitis, ultrasound, dichotomized controlled attenuation parameter and body mass index showed performance of 58.2%, 82.3% and 46.7%, respectively, whereas in patients without chronic viral hepatitis, the performance was 86.4%, 68.6% and 48.6% respectively. CONCLUSIONS In patients with chronic viral hepatitis and advanced liver fibrosis, controlled attenuation parameter performs better than ultrasound for assessing liver steatosis, whereas in patients without viral hepatitis and with nonsignificant liver disease ultrasound shows the best performance.

Abstract
OBJECTIVE Sialic-acid-binding immunoglobulin-like lectin-7 (Siglec-7) is a natural killer (NK) cell inhibitory receptor associated with NK phenotypic and functional abnormalities in HIV-1 infection. We investigated the significance of NK-expressed and serum soluble Siglec-7 in relation to NK functional ability and parameters of liver necroinflammation and fibrosis in chronic HCV infection. DESIGN NK-expressed and serum Siglec-7 were evaluated in 130 and 166 HCV-infected individuals by flow cytometry and ELISA, respectively. NK cell degranulation and cytokine secretion were determined by flow cytometry. 65 patients with chronic HBV infection, 84 with chronic biliary disorders and 168 healthy donors served as controls. RESULTS Expression of Siglec-7 was significantly decreased on NK cells from HCV-infected and HBV-infected patients and, conversely, serum Siglec-7 was significantly increased in these patients compared with controls. The frequency of Siglec-7pos NK cells was significantly higher at baseline in sustained virological responders to pegylated interferon-α/ribavirin treatment than in non-responders. Activating receptor expression was significantly higher in Siglec-7pos NK cells and was associated with increased degranulation and cytokine secretion compared with Siglec-7neg cells. In chronic HCV infection, there was an inverse correlation between Siglec-7 expression and serum aminotransferases, γ-glutamyl transpeptidase, liver stiffness, aspartate aminotransferase to platelet ratio index and fibrosis-4 scores, and a positive correlation between serum Siglec-7 and the same clinical parameters, including histological staging. CONCLUSIONS These findings identify Siglec-7neg NK cells as a dysfunctional subpopulation associated with severe liver disease in chronic HCV infection.

Abstract
BACKGROUND Extracorporeal shockwave therapy (ESWT) is effective in reducing shoulder pain and improving function in calcific supraspinatus tendinopathy. Eccentric exercise has been introduced as an effective treatment choice for Achilles tendinopathy, but poor evidence exists about its role in the treatment of rotator cuff tendinopathy. AIM To investigate if adding a supervised eccentric training of the shoulder abductor muscles could improve the outcome of ESWT. DESIGN Pre-post intervention pilot study with matched control-group. SETTING Outpatient, University Hospital. POPULATION Twenty-two subjects affected by painful supraspinatus calcific tendinopathy. METHODS The study-group was assigned to receive focal ESWT (f-ESWT) plus a supervised eccentric training (SET) of the shoulder abductor muscles. The matched control-group received f-ESWT only. The post-treatment assessment at follow-up (T1) was performed nine weeks after the enrollment (T0). We assessed shoulder pain and function by the means of a numeric rating scale (p-NRS) and a DASH scale. As secondary outcome, we measured the isometric strength of the abductor muscles of the affected shoulder using a handheld dynamometer. RESULTS At T1, we recorded a significant decrease in pain (P<0.001) and an improvement in upper limb function (P<0.001) in both groups. However, we observed no statistical differences in favor of the study-group, in terms of p-NRS and DASH total score. A mild increase (+13% from baseline) of the maximum isometric abduction strength was noticed in the study group at T1. CONCLUSIONS Our findings did not support the hypothesis that adding a supervised eccentric training of the shoulder abductor muscles could improve the outcome (pain and function) of shock wave therapy. CLINICAL REHABILITATION IMPACT Our study confirmed that f-ESWT is effective in reducing shoulder pain and improving function in calcific supraspinatus tendinopathy. Adding a supervised eccentric training, focused on the abductor muscles, was useful to improve maximum isometric abduction strength, but appeared to give no advantage in the short-term outcome of shock wave therapy.

Abstract
BACKGROUND Whole lung lavage (WLL) is the current standard of care treatment for patients affected by pulmonary alveolar proteinosis (PAP). However, WLL is not standardized and international consensus documents are lacking. Our aim was to obtain a factual portrayal of WLL as currently practiced with respect to the procedure, indications for its use, evaluation of therapeutic benefit and complication rate. METHODS A clinical practice survey was conducted globally by means of a questionnaire and included 27 centers performing WLL in pediatric and/or adult PAP patients. RESULTS We collected completed questionnaires from 20 centres in 14 countries, practicing WLL in adults and 10 centers in 6 countries, practicing WLL in pediatric patients. WLL is almost universally performed under general anesthesia, with a double-lumen endobronchial tube in two consecutive sessions, with an interval of 1-2 weeks between sessions in approximately 50 % of centres. The use of saline warmed to 37 °C, drainage of lung lavage fluid by gravity and indications for WLL therapy in PAP were homogenous across centres. There was great variation in the choice of the first lung to be lavaged: 50 % of centres based the choice on imaging, whereas 50 % always started with the left lung. The choice of position was also widely discordant; the supine position was chosen by 50 % of centres. Other aspects varied significantly among centres including contraindications, methods and timing of follow up, use of chest percussion, timing of extubation following WLL and lung isolation and lavage methods for small children. The amount of fluid used to perform the WLL is a critical aspect. Whilst a general consensus exists on the single aliquot of fluid for lavage (around 800 ml of warm saline, in adults) great variability exists in the total volume instilled per lung, ranging from 5 to 40 liters, with an average of 15.4 liters/lung. CONCLUSIONS This international survey found that WLL is safe and effective as therapy for PAP. However these results also indicate that standardization of the procedure is required; the present survey represents the a first step toward building such a document.

Abstract
The clinical course of IgA nephropathy (IgAN) and its outcome are extremely variable. Proteinuria at baseline has been considered one of the most important risk factors. More recently, mean proteinuria of follow-up (time-average proteinuria: TAp) was described as a stronger marker of renal survival, suggesting to consider it as a marker of disease activity and response to treatment. We evaluated predictors of renal survival in IgAN patients with different degrees of renal dysfunction and histological lesions, focusing on the role of the therapy in influencing TAp. We performed a retrospective analysis of three prospective, randomized, clinical trials enrolling 325 IgAN patients from 1989 to 2005. Patients were divided into 5 categories according to TAp. The primary endpoint of the 100% increase of serum creatinine occurred in 54 patients (16.6%) and renal survival was much better in groups having lower TAp. The median follow up was 66.6 months (range 12 to 144). The primary endpoint of the 100% increase of serum creatinine occurred in 54 patients (16,6%) and renal survival was much better in groups having lower TA proteinuria. At univariate analysis plasma creatinine and 24h proteinuria, systolic (SBP) and diastolic (DBP) blood pressure during follow-up and treatment with either steroid (CS) or steroid plus azathioprine (CS+A) were the main factors associated with lower TAp and renal survival. At multivariate analysis, female gender, treatment with S or S+A, lower baseline proteinuria and SBP during follow-up remained as the only variables independently influencing TAp. In conclusion, TA-proteinuria is confirmed as one of the best outcome indicators, also in patients with a severe renal insufficiency. A 6-month course of corticosteroids seems the most effective therapy to reduce TAp.

Abstract
AbstractObjective:To evaluate the secular trends in MRSA BSIs after the introduction of a nosocomial MRSA control intervention.Design:Before-after study.Setting:An 850-bed community hospital with an ICU and vascular surgery, neurosurgery, bone marrow transplantation, and AIDS units. MRSA is endemic at this hospital; the prevalence of methicillin resistance among patients withS. aureusinfection is greater than 50%.Patients:Among all inpatients, MRSA BSI was identified, its origin defined, and incidence rates calculated by ward and origin.Intervention:A MRSA control program was implemented based on active surveillance cultures to identify MRSA-colonized patients, followed by isolation using contact precautions. Incidence rates of MRSA BSI during the intervention (ie, July 1, 1997, to December 31, 2001) and preintervention (ie, January 1, 1996, to June 30, 1997) periods were compared.Results:Sixty-nine MRSA BSIs were identified. When compared with the preintervention period, the incidence rate of MRSA BSI was reduced from 0.64 to 0.30 per 1,000 admissions (RR, 0.46; CI95, 0.25–0.87;P= .02) during the intervention period. The impact was greater in the ICU, with an 89% reduction (RR, 0.11; CI95, 0.01–0.98;P= .03), and for CVC-associated MRSA BSIs, with an 82% decrease (RR, 0.17; CI95, 0.05–0.55;P= .002). Methicillin resistance amongS. aureusblood isolates decreased from 46% to 17% (RR, 0.36; CI95, 0.22–0.62;P= .0002).Conclusion:A reduction in MRSA bacteremia is achievable through use of the MRSA “search and isolate” intervention even in a hospital with high rates of endemic MRSA.

Abstract
BACKGROUND Patients with childhood-onset GH deficiency (GHD) are usually retested after achievement of near final height, to verify whether they need to continue GH treatment. We investigated if GH stimulation test is necessary to confirm a persistent status of GHD or if other parameters could be a reliable predictor of GHD persistence. METHODS One-hundred and sixty-four children with idiopathic GHD (55 females and 109 males) were retested when they reached near final height using GH releasing hormone (GHRH)+arginine test or arginine alone. RESULTS At diagnosis, 23.8% of patients showed severe GHD (GH peak at diagnosis <5 ng/mL) and 76.2% showed partial GHD (GH peak <10 ng/mL). At time of retesting, 82.1% of severe GHD and 82.4% of partial GHD patients showed transient GHD. IGF-I levels were not different between persistent (0.18±1.18 SDS) and transient GHD subjects (0.17±0.82 SDS). Furthermore, among persistent severe GHD patients only two showed very reduced levels of IGF-I (<-2.0 SDS). CONCLUSIONS The majority of patients idiopathic GHD proved to be transient. IGF-I levels alone do not discriminate subjects with persistent from those with transient GHD. Therefore, after the end of GH substitutive treatment, a re-evaluation of GH secretion is mandatory to verify the persistence of GHD in adulthood.

Abstract
PURPOSE To evaluate the inter-device reproducibility of retrobulbar blood flow measurements obtained by two commercially available CDI (color Doppler imaging) devices. METHODS The right eyes of 10 healthy volunteers were investigated. Four examiners, namely two ophthalmologists and two radiologists, performed CDI examination of the ophthalmic artery, central retinal artery and temporal short posterior ciliary arteries using both CDI devices: ESAOTE MYLAB™ and SIEMENS ANTARES STELLAR PLUS™. The peak systolic velocity (PSV), the end-diastolic velocity (EDV) and the resulting resistivity index (RI) were averaged for 3 cardiac cycles. To evaluate the reproducibility between both device measurements, the Lin's concordance correlation coefficient (CCC) was used. CCC can be expressed as the product of Pearson's r (the measure of precision) and C_b (the measure of accuracy). RESULTS Results show that the inter-device reproducibility for CDI measurements is not acceptable since a poor degree of overall concordance (0.15<CCC<0.37) was obtained: accuracy was high (C_b > 0.71) but overall precision low (0.18< Pearson's r <0.47). Ophthalmologists and radiologists obtained similar results. CONCLUSIONS To evaluate the causal role of blood flow abnormalities in glaucoma, CDI analysis using different devices seems unreliable. CDI inter-device reproducibility seems unrelated to medical speciality of the examiners. However, to improve present results, the use of similar probes and standardized CDI instrument settings as well as a CDI images analysis by a single grader, might possibly improve the inter-device reproducibility when testing the retrobulbar blood flow velocity.

Abstract
BACKGROUND AND OBJECTIVE Time-average proteinuria (TAp) is the strongest predictor of renal survival in IgA nephropathy (IgAN). Little is known about the utility and safety of corticosteroids (CS) to obtain TAp<1 g/d in patients with advanced IgAN. This study sought to evaluate TAp at different degree of baseline renal function and histologic severity during CS use and to investigate treatment safety. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We performed one-stage individual-patient data meta-analysis among 325 patients with IgAN enrolled in three prospective, randomized clinical trials. Patients were divided into three groups according to treatment: no treatment (NT; supportive therapy), CS, and CS plus azathioprine (CS+A). Associations of TAp with histologic grading, treatment, and eGFR at baseline were performed with linear regression models for repeated measures. The median follow-up duration was 66.6 months (range, 12-144 months). RESULTS In the first 6 months, proteinuria did not change in the NT group and decreased substantially in the other groups(CS: from a mean±SD of 2.20±1.0 to 0.8 [interquartile range, 0.4-1.2] g/d; CS+A: from 2.876±2.1 to 1.0 [interquartile range, 0.5-1.7] g/d), independent of the degree of histologic damage and baseline eGFR. The percentage of patients who maintained TAp<1 g/d was 30.2% in the NT, 67.3% in the CS, and 66.6% in the CS+A group. Thirty-four patients experienced adverse events: none in the NT, 11 (6.4%) in the CS, and 23 (20.7%) in the CS+A group. The risk of developing adverse events increased with decreasing levels of eGFR (from 2.3% to 15.4%). The addition of azathioprine to CS further increased the percentage of patients with adverse events (16.8% versus 5.7% in study 2 and 30.0% versus 15.4% in study 3; overall P<0.001). CONCLUSIONS In patients with IgAN, CS can reduce proteinuria and increase the possibility of maintaining TAp<1 g/d, regardless of the stage of CKD and the histologic damage. The risk of major adverse events is low in patients with normal renal function but increases in those with impaired renal function and with the addition of azathioprine.

Abstract
BACKGROUND Chronic subdural hematoma (CSDH) can have a negative impact on autonomy of the elderly. Ambulatory and functional status may remain limited despite successful surgical evacuation. AIM To evaluate the outcome of a postoperative assisted rehabilitation program. DESIGN Single-institution short-term observational study. SETTING Inpatient (Neurosurgery Unit of a University Hospital). POPULATION Thirty-five patients, aged 65 or older, who underwent burr-hole drainage for chronic subdural hematoma. METHODS Postoperatively all participants underwent a rehabilitation program, described in details, aimed at recovering standing position and gait as soon as possible. The program involved daily 30-minute individual sessions assisted by a physiotherapist, until discharge from hospital. The Markwalder's Grading Scale was used to assess the neurological status preoperatively and at discharge. The Trunk Control Test, the Standing Balance by Bohannon Scale and the Modified Rankin Scale were used to evaluate balance and general function (primary outcome) in the immediate postoperative and at discharge. We also recorded the rate of pre-CSDH walking patients who maintained ambulation at discharge and the discharge destination (secondary outcome). RESULTS Total scores of Markwalder's Grading Scale, Trunk Control Test, Standing Balance by Bohannon Scale and Modified Rankin Scale improved (P<0.05), indicating a global favorable outcome, especially for balance. Excluding the patients who were dependent pre-CSDH, the others maintained gait function in 74.2% of cases. Only 45.7% of the patients were discharged home, the others being divided between inpatient medical settings and rehabilitation. CONCLUSIONS The rehabilitation program was well tolerated by the patients. Our study showed a clear improvement in trunk control and standing balance and an overall favorable outcome for neurological and ambulatory status at discharge. Despite an assisted postoperative rehabilitation program, the residual impairment in general function was the main factor that prevents us to discharge more elderly patients home rather than to assisted settings. CLINICAL REHABILITATION IMPACT The results of this descriptive study suggest that an assisted rehabilitation program may be helpful in improving short-term postoperative balance and ambulatory status (more than functional status), but further studies, with a randomized controlled design, are certainly justified to understand the efficacy of rehabilitation in this context.

Abstract
PURPOSE To compare patency in dialysis patients following different endovascular treatment of symptomatic central venous stenosis. MATERIALS AND METHODS A 10-year retrospective evaluation in 70 patients (32 men) dialyzing through vascular access (33, 47%) and tunneled catheters (37, 53%) was made. Three cohorts were compared: angioplasty alone (22), bare metal stent (28), and stent graft (20). Patencies were described with Kaplan-Meier method, and Cox uni- and multivariate models were analyzed to find factors associated. RESULTS All patients had a favorable anatomical and clinical outcome. Restenosis occurred in 22 (31%) of 70 patients requiring 41 additional interventions; 34 of 70 patients died (median follow-up 19.4 months). Primary patency at 3, 6, 12, and 24 months was 100%, 100%, 100%, and 84% for stent graft versus 90%, 79%, 58%, and 43% for angioplasty (P = .014) versus 84%, 80%, 75%, and 46% for bare-metal stent (P = .062). The overall comparison was more favorable for stent graft (P = .020) when the sites of lesions were matched. Patencies for angioplasty and bare-metal stents were equivalent (P = .141). A lower risk of restenosis (hazard rate [HR] 0.20, confidence interval [CI] 0.06-0.7) and fewer reinterventions (P < .01) were associated with stent graft, whereas age (HR 1.04, CI 1.001-1.08) and cardiovascular disease (HR 2.26, CI 1.06-4.84) influenced the overall survival. No difference in assisted primary patency was found. CONCLUSION Stent graft seems to improve primary patency for central venous stenosis and requires fewer reinterventions in a dialysis population with a high prevalence of long-term catheters.

Abstract
Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare disorder which can be an incidental finding in imaging tests performed during the investigation of another condition, or is the final diagnosis in patients evaluated for chronic obstructive complaints. To explore the possible association between specific histopathology features and the mode of clinical presentation, we retrieved the clinical, functional, radiological, and pathological data of all 13 patients diagnosed with DIPNECH at our Institution over a 14-year period (2000-2014). As compared to patients with incidental disease (6/13, 46 %), patients with symptomatic disease were younger [mean (SD): 57.7 vs. 68.7 years, p = 0.046], were more likely to have mosaic attenuation (100 vs. 0 %, p = 0.001) and small multiple nodules (100 vs. 17 %, p = 0.005) at CT, and showed a significantly higher number of foci of linear neuroendocrine proliferation [median (IQR): 28 (13-37) vs. 6 (5-13), p = 0.018] and of tumorlets [median (IQR): 10 (8-20) vs. 1 (1-1), p = 0.002] at histology. Incidental disease was found in association with pulmonary adenocarcinoma in five out of six patients (83.3 %). The results of our study provide preliminary evidence that symptomatic patients with DIPNECH represent a specific subset characterized by younger age and a higher burden of foci of neuroendocrine proliferation.

Abstract
BACKGROUND The diagnosis of cystic echinococcosis (CE) is based primarily on imaging, in particular with ultrasound for abdominal CE, complemented by serology when imaging results are unclear. In rural endemic areas, where expertise in ultrasound may be scant and conventional serology techniques are unavailable due to lack of laboratory equipment, Rapid Diagnostic Tests (RDTs) are appealing. METHODOLOGY/PRINCIPAL FINDINGS We evaluated the diagnostic accuracy of 3 commercial RDTs for the diagnosis of hepatic CE. Sera from 59 patients with single hepatic CE cysts in well-defined ultrasound stages (gold standard) and 25 patients with non-parasitic cysts were analyzed by RDTs VIRapid HYDATIDOSIS (Vircell, Spain), Echinococcus DIGFA (Unibiotest, China), ADAMU-CE (ICST, Japan), and by RIDASCREEN Echinococcus IgG ELISA (R-Biopharm, Germany). Sensitivity, specificity and ROC curves were compared with McNemar and t-test. For VIRapid and DIGFA, correlation between semiquantitative results and ELISA OD values were evaluated by Spearman's coefficient. Reproducibility was assessed on 16 randomly selected sera with Cohen's Kappa coefficient. Sensitivity and Specificity of VIRapid (74%, 96%) and ADAMU-CE (57%, 100%) did not differ from ELISA (69%, 96%) while DIGFA (72%, 72%) did (p = 0.045). ADAMU-CE was significantly less sensitive in the diagnosis of active cysts (p = 0.019) while DIGFA was significantly less specific (p = 0.014) compared to ELISA. All tests were poorly sensitive in diagnosing inactive cysts (33.3% ELISA and ADAMU-CE, 42.8% DIGFA, 47.6% VIRapid). The reproducibility of all RDTs was good-very good. Band intensity of VIRapid and DIGFA correlated with ELISA OD values (r = 0.76 and r = 0.79 respectively, p<0.001). CONCLUSIONS/SIGNIFICANCE RDTs may be useful in resource-poor settings to complement ultrasound diagnosis of CE in uncertain cases. VIRapid test appears to perform best among the examined kits, but all tests are poorly sensitive in the presence of inactive cysts, which may pose problems with accurate diagnosis.

Abstract
Alpha1-antitrypsin Deficiency (AATD) is a rare hereditary disorder with an estimated prevalence of about 1/5000 individuals in Italy. Deficient patients are at a higher risk of developing lung emphysema and chronic liver disease. The low estimated prevalence of AATD prompted the establishment of a registry with the aim of learning more about the natural history and the quality of care of these patients. The Italian registry for AATD was established in 1996. In this study, genetic and clinical findings of Italian AATD patients are presented. Moreover, we also evaluated the changes in health-related quality of life (HRQoL) in patients with COPD and AAT deficiency over a three-year period, in relation to augmentation therapy. In a period spanning 18 years (1996-2014) a total of 422 adult subjects with severe AATD were enrolled, namely 258 PI*ZZ, 74 PI*SZ, 4 PI*SS and 86 patients with at least one rare deficient allele. The 21.3% frequency for AATD patients with at least one deficient rare variant is the highest so far recorded in national registries of AATD. The registry data allow a detailed characterization of the natural course of the disease and the level of patient care, as well as confirm the usefulness of early AATD detection.

Abstract
BACKGROUND Chemotherapy-induced immune suppression has mainly been studied in patients with advanced cancer, but the influence of chemotherapy on the immune system in early stage cancer patients has so far not been studied systematically. The aim of the present study was to monitor the immune system during anthracycline- and taxane-based adjuvant chemotherapy in early stage breast cancer patients, to assess the impact of circulating tumor cells on selected immune parameters and to reveal putative angiogenic effects of circulating endothelial cells. METHODS Peripheral blood samples from 20 early stage breast cancer patients were analyzed using a flow cytometric multi-color of antibodies to enumerate lymphocyte and dendritic cell subsets, as well as endothelial and tumor cells. An enzyme-linked immunosorbent assay (ELISA) was used to measure the levels of various serological factors. RESULTS During chemotherapy, all immunological parameters and angiogenesis surrogate biomarkers showed significant decreases. The numbers of circulating tumor cells showed significant inverse correlations with the numbers of T helper cells, a lymphocyte subset directly related to effective anti-tumor responses. Reduced T helper cell numbers may contribute to systemic immunosuppression and, as such, the activation of dormant tumor cells. CONCLUSIONS From our results we conclude that adjuvant chemotherapy suppresses immune function in early stage breast cancer patients. In addition, we conclude that the presence of circulating tumor cells, defined as pan-cytokeratin(+), CD326(+), CD45(-) cells, may serve as an important indicator of a patient's immune status. Further investigations are needed to firmly define circulating tumor cells as a predictor for the success of breast cancer adjuvant chemotherapy.

Abstract
Background Glaucoma is an optic neuropathy characterized by retinal ganglion cells (RGC) loss and retinal nerve fiber layer (RNFL) injury: this results in functional and morphological changes. The first can be observed by Standard Automated Perimetry (SAP), the second by Optic Coherence Tomography (OCT) that measures the RNFL and ganglion cell complex (GCC) thicknesses. Nevertheless, diagnosis of early glaucoma may be difficult. Recently, Medeiros et al. derived an empirical formula combining the measurement of structural and functional tests to provide an estimate of RGC. The aim of the current study is to analyse the correlation between RGC count, estimated by Medeiros’ formula, and the structural and functional parameters in patients examined for glaucoma and to evaluate SAP, OCT and RGC counts capability to discriminate the weight of the disease itself. Methods Ninety four eyes of 50 consecutive patients clinically referring to glaucoma service of the Universitary Eye Clinic were submitted to a complete ophthalmic evaluation including SAP and Spectral Domain OCT (SD-OCT) of RNFL and macular GCC. Average thickness of RNFL and macular GCC, parameters Global Loss Volume (GLV) and Focal Loss Volume (FLV) over the entire GCC map were taken into account. Estimates of RGC were obtained with the help of a model already published by Medeiros et al. combining light sensitivities from SAP and retinal thickness from OCT. The RGC count was estimated in the entire visual field (central 24°) and in the GCC macular area and then compared with functional and morphological parameters applying Pearson’s correlation coefficient. Results After the classification of the patients by the Glaucoma Staging System 2 of Brusini, we noticed a good correlation among the functional parameters considered, even if the Visual Field Index is unable to identify early glaucoma. An analogous result can be observed for structural data (RNFL and GCC). The correlation detected between functional and structural parameters was moderate. Great differences in RGC counts were found between groups at various stages of glaucoma. GLV showed highest level of correlation (r > −0.8) with RCG counts. Conclusions Estimate circumpapillary and macular RGC counts can discriminate various stages of the disease and there is also a good/very good correlation with both functional and structural parameters. GLV could be used instead of RGC counts in clinical practice.

Abstract
BACKGROUND Experts and scientific society guidelines recommend that rapid on-site evaluation (ROSE) be used with endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) to optimize lung cancer genotyping, but no comparative trial has been carried out to confirm and quantify its usefulness. METHODS To assess the influence of ROSE on the yield of EBUS-TBNA for a multigene molecular analysis of lung cancer samples, consecutive patients with suspected or known advanced lung cancer were randomized to undergo EBUS-TBNA without ROSE (EBUS arm) or with ROSE (ROSE arm). The primary end point was the rate of the successful accomplishment of the institution's clinical protocol for molecular profiling of nonsquamous non-small cell lung cancer (EGFR and KRAS testing, followed by ALK testing for tumors with EGFR and KRAS wild-type status). RESULTS Complete genotyping was achieved in 108 of 126 patients (85.7%) (90.8% in the ROSE arm vs 80.3% in the EBUS arm, P = .09). The patients in the ROSE arm were less likely to have samples that could be used only for pathologic diagnosis because of minimal tumor burden (0 vs 6, P = .05), and were more likely to have the bronchoscopy terminated after a single biopsy site (58.9% vs 44.1%, P = .01). CONCLUSIONS ROSE prevents the need for a repeat invasive diagnostic procedure aimed at molecular profiling in at least one out of 10 patients with advanced lung cancer and significantly reduces the risk of retrieving samples that can be used only for pathologic subtyping because of minimal tumor burden.

Abstract
Confirmation of endoscopically suspected esophageal metaplasia (ESEM) requires histology, but confusion in the histological definition of columnar-lined esophagus (CLE) is a longstanding problem. The aim of this study is to evaluate interpathologist variability in the interpretation of CLE. Thirty pathologists were invited to review three ten-case sets of CLE biopsies. In the first set, the cases were provided with descriptive endoscopy only; in the second and the third sets, ESEM extent using Prague criteria was provided. Moreover, participants were required to refer to a diagnostic chart for evaluation of the third set. Agreement was statistically assessed using Randolph's free-marginal multirater kappa. While substantial agreement in recognizing columnar epithelium (K = 0.76) was recorded, the overall concordance in clinico-pathological diagnosis was low (K = 0.38). The overall concordance rate improved from the first (K = 0.27) to the second (K = 0.40) and third step (K = 0.46). Agreement was substantial when diagnosing Barrett's esophagus (BE) with intestinal metaplasia or inlet patch (K = 0.65 and K = 0.89), respectively, in the third step, while major problems in interpretation of CLE were observed when only cardia/cardia-oxyntic atrophic-type epithelium was present (K = 0.05-0.29). In conclusion, precise endoscopic description and the use of a diagnostic chart increased consistency in CLE interpretation of esophageal biopsies. Agreement was substantial for some diagnostic categories (BE with intestinal metaplasia and inlet patch) with a well-defined clinical profile. Interpretation of cases with cardia/cardia-oxyntic atrophic-type epithelium, with or without ESEM, was least consistent, which reflects lack of clarity of definition and results in variable management of this entity.

Abstract
Objectives Demonstrate the safety and effectiveness of highly purified CD133+ autologous stem cells in critical limb ischemia (CLI). Design Prospective single-center not randomized. Clinicaltrials.gov identifier: NCT01595776 Methods Eight patients with a history of stable CLI were enrolled in a period of 2 years. After bone marrow stimulation and single leukapheresis collection, CD133+ immunomagnetic cell selection was performed. CD133+ cells in buffer phosphate suspension was administered intramuscularly. Muscular and arterial contrast enhanced ultra sound (CEUS), lesion evolution and pain management were assessed preoperatively and 3, 6 and 12 months after the implant. Results No patient had early or late complications related to the procedure. Two patients (25 %) didn’t get any relief from the treatment and underwent major amputation. Six patients (75 %) had a complete healing of the wounds, rest pain cessation and walking recovery. An increase in CEUS values was shown in all eight patients at 6 months and in the six clinical healed patients at 12 months and had statistical relevance. Conclusions Highly purified autologous CD133+ cells can stimulate neo-angiogenesis, as based on clinical and CEUS data.

Abstract
AIM To evaluate the effects on glycemic excursions during bicarbonate dialysis (BHD) compared to hemodiafiltration (HDF) in type 2 diabetic or not diabetic patients affected by end-stage renal disease (ESRD). MATERIAL AND METHODS Thirty-six patients (20 affected by type 2 diabetes mellitus, and 16 not diabetic patients) were evaluated and underwent BHD dialysis, followed by HDF dialysis two days later. All patients underwent also glucose continuous monitoring system, using iPro Continuous Glucose Monitor System (Medtronic MiniMed) starting just before the BHD, and ending five days later, two days after the HDF dialysis. Glycemic control was estimated as the mean blood glucose (MBG), the area under the glucose curve above 70mg/dl (AUC>70) or 180mg/dl (AUC>180), and the percentage of time above 70mg/dl (t>70) or 180mg/dl (t>180). Intraday glycemic variability was assessed as the standard deviation (SD), M value, and the mean amplitude of glycemic excursions (MAGE). Day-to-day glycemic variability was assessed as the mean of daily difference (MODD), that is the mean of the absolute difference among glucose values taken on 2 consecutive days at the same time. RESULTS glycemic control was better with HDF: MBG, and AUC>180 were lower during HDF compared do BHD. We also observed a significant decrease of glycemic excursions during HDF dialysis: SD, M value, and the MAGE value were lower with HDF. The MODD value was significantly changed in BHD group, while no differences were recorded during HDF. CONCLUSION HDF seems to greater reduce glycemic excursions during the treatment compared to BHD.

Abstract
Knowledge of variables influencing serology is crucial to evaluate serology results for the diagnosis and clinical management of cystic echinococcosis (CE). We analyzed retrospectively a cohort of patients with hepatic CE followed in our clinic in 2000-2012 to evaluate the influence of several variables on the results of commercial enzyme-linked immunosorbent assay (ELISA) and indirect hemagglutination (IHA) tests. Sera from 171 patients with ≥ 1 hepatic CE cyst, and 90 patients with nonparasitic cysts were analyzed. CE cysts were staged according to the WHO-IWGE classification and grouped by activity. A significant difference in ELISA optical density (OD) values and percentage of positivity was found among CE activity groups and with controls (P < 0.001). The serological response was also influenced by age (P < 0.001) and cyst number (P = 0.003). OD values and cyst size were positively correlated in active cysts (P = 0.001). IHA test showed comparable results. When we analyzed the results of 151 patients followed over time, we found that serology results were significantly influenced by cyst activity, size, number, and treatment ≤ 12 months before serum collection. In conclusion, serological responses as assessed by commercial tests depend on CE cyst activity, size and number, and time from treatment. Clinical studies and clinicians in their practice should take this into account.
