Abstract
Abstract
Children and young people are particularly sensitive to the environmental pollution which is closely related to degenerative diseases. Several studies show that a genotoxic damage during young age can increase the risk of chronic diseases in adulthood. The young people are more vulnerable than adults to the environmental pollutants because they spend more time outdoors, they have immaturity of some organs and of the mechanisms involved in the cellular repair. In the present study, the early biological effects of exposure to a particularly polluted area of Southern Italy were evaluated in 200 children (6-10 year-old) and 100 young people (18-25 year-old). This area, worldwide known as Sarno basin, is characterized by strong anthropization, many agro-food processing industries, massive use of fertilizers and pesticides in agricultural practices and a strong river pollution. The comet assay was chosen because it reflects cumulative exposure to a variety of environmental factors and it was performed on salivary leukocytes in the children selected for the survey, while in the young people the DNA damage was evaluated in human peripheral blood lymphocytes. As in previous studies were not find significant differences between salivary leukocytes and blood lymphocytes we preferred the sampling of saliva for the children to avoid bloody practices. Furthermore, before cell sampling the children's parents were interviewed using an ad hoc questionnaire designed to gather additional information about exposure sources. A questionnaire was administered also to the young people to have more information on their lifestyle and some characteristic of the area of exposure (vehicular traffic and so on). The results showed a clear damage from exposure in the children differently from young people.
Key messages
Comet assay was performed in vitro on lymphocytes of 200 children (6-10 year-old) and 100 young people (18-25 year-old) exposed to a particularly polluted area of Southern Italy. An evident DNA damage was observed in lymphocytes coming from children; no genetic material alterations were observed in young people.

Abstract
BACKGROUND AND PURPOSE Neuromodulation is a promising approach to increasing motor recovery in stroke; however, to date, there is a scarcity of evidence documenting the clinical potential of transcranial direct current stimulation (tDCS) administered in the acute phase of stroke. The present study aims to examine the clinical effects of a treatment involving the application of tDCS in the acute stage post-stroke. METHODS This was a randomized, double-blind, sham-controlled trial. A cohort of 32 stroke patients with severe motor impairment underwent 5 days of treatment with real or sham bi-hemispheric tDCS over the motor cortex. During the treatment, tDCS was applied twice per day (two daily applications each of 15 min), starting 48 to 72 h after stroke onset. RESULTS We found statistically significant improvements after both real and sham tDCS treatments in primary (hand grip strength, Motricity Index) and secondary (National Institutes of Health Stroke Scale score, Barthel Index) outcomes. Patients receiving real tDCS showed a larger improvement of upper-limb muscle strength at the end of treatment phase; this advantage was no longer present after 6 months. CONCLUSIONS Transcranial direct current stimulation may be used to accelerate the rate of upper-limb motor recovery during the spontaneous recovery period.

Abstract
Prevalence and clinical impact of viral respiratory tract infections (VRTIs) on community-acquired pneumonia (CAP) has not been well defined so far. The aims of this study were to investigate the prevalence and the clinical impact of VRTIs in patients with CAP. Prospective study involving adult patients consecutively admitted at medical wards for CAP and tested for VRTIs by real-time PCR on pharyngeal swab. Patients' features were evaluated with regard to the presence of VRTI and aetiology of CAP. Clinical failure was a composite endpoint defined by worsening of signs and symptoms requiring escalation of antibiotic treatment or ICU admission or death within 30 days. 91 patients were enrolled, mean age 65.7 ± 10.6 years, 50.5% female. 62 patients (68.2%) had no viral co-infection while in 29 patients (31.8%) a VRTI was detected; influenza virus was the most frequently identified (41.9%). The two groups were similar in terms of baseline features. In presence of a VRTI, pneumonia severity index (PSI) was more frequently higher than 91 and patients had received less frequently pre-admission antibiotic therapy (adjusted OR 2.689, 95% CI 1.017-7.111, p = 0.046; adjusted OR 0.143, 95% CI 0.030-0.670, p = 0.014). Clinical failure and antibiotic therapy duration were similar with regards to the presence of VRTI and the aetiology of CAP. VRTIs can be detected in almost a third of adults with CAP; influenza virus is the most relevant one. VRTI was associated with higher PSI at admission, but it does not affect patients' outcome.

Abstract
BACKGROUND The goal of this study was to assess the prevalence of myocardial microvascular dysfunction in rheumatoid arthritis (RA) patients without clinical cardiovascular disease and its association with RA characteristics and measures of cardiac structure and function. METHODS Participants with RA underwent rest and vasodilator stress N-13 ammonia positron emission tomography and echocardiography. Global myocardial blood flow was quantified at rest and during peak hyperemia. Myocardial flow reserve (MFR) was calculated as peak stress myocardial blood flow/rest myocardial blood flow. A small number of asymptomatic and symptomatic non-RA controls were also evaluated. RESULTS In RA patients, mean±SD MFR was 2.9±0.8, with 29% having reduced MFR (<2.5). Male sex and higher interleukin-6 were significantly associated with lower MFR, while the use of tumor necrosis factor inhibitors was associated with higher MFR. Lower MFR was associated with higher left ventricle mass index and higher left ventricle volumes but not with ejection fraction or diastolic dysfunction. RA and symptomatic controls had comparable MFR (mean±SD: 2.9±0.8 versus 2.55±0.6; P=0.48). In contrast, MFR was higher in the asymptomatic controls (mean±SD: 3.25±0.7) although not statistically different. CONCLUSIONS Reduced MFR was observed in a third of RA patients without clinical cardiovascular disease and was associated with a measure of inflammation and with higher left ventricle mass and volumes. MFR in RA patients was similar to controls referred for clinical scans (symptomatic controls). Whether reduced MFR contributes to the increased risk for heart failure in RA remains unknown.

Abstract
Abstract
BACKGROUND
Glioblastoma (GBM) remains the most common malignant primary brain tumor in adults. Most patients with GBM & an unmethylated O-6-methylguanine-DNA methylase (MGMT) gene promoter, have a poor prognosis with approximately 20% of patients surviving to 2 years. Poor prognosis is likely related to a number of factors including a highly immunosuppressive tumor microenvironment (TME). The TME in GBM is mainly composed of tumor associated macrophages (TAMs) & microglia. A subset of tumor-infiltrating macrophages characterized by expression of the angiopoietin receptor Tie2 (TEMs) have features of M2-TAMs, promote tumor angiogenesis & are infrequently found in normal organs. Tie2 is significantly upregulated upon homing to tumors. Gene therapy technology has allowed TEMs to be used as carriers for the local and tumor restricted release of interferon-α (IFN). IFN has antitumor effects, inhibits angiogenesis & modulates the immune system. Cell-based delivery of IFN into the TME by TEMs is expected to provide efficacy, taking advantage of pleiotrophic anti-tumor effects & avoiding tolerability issues associated with systemic IFN treatment.
MATERIAL AND METHODS
We are currently conducting a Phase I/IIa clinical study in Milan to evaluate this therapeutic approach (Temferon) in 21 patients with GBM & unmethylated MGMT promoter (EudraCT Number 2018- 001404-11). The study recruits & follows up patients at a specialist neurosurgical & neuro-oncology unit (INCB); administration of Temferon & hematological follow up takes place at a specialist hematology & bone marrow transplantation unit at OSR. Potentially eligible patients are identified immediately after first surgical resection of GBM once the MGMT promoter methylator status is known. Once screening procedures have been completed, harvesting of HSPCs occurs followed by 6 weeks of radiotherapy. Patients receive a non-myeloablative conditioning regimen consisting of BCNU & thiotepa. This is followed by administration of non-manipulated HSPCs and Temferon. In-patient monitoring occurs until hematological recovery. Thereafter, regular follow-up of patients occurs up to 2 years (+720 days) and patients will be invited to participate in a long term follow-up study lasting an additional 6 years.
RESULTS
In Part A of the study, 3 cohorts of 3 patients will receive escalating doses of Temferon. On completion of Part A, a single dose of Temferon will be selected to be studied in a further 12 patients in Part B. Criteria for study eligibility are the same for both Part A and Part B. In the event that GBM disease progression occurs, patients will be managed with second line therapies including second surgery, TMZ, BCNU, fotemustine or any other approved therapy for GBM. Patient recruitment for Part A is ongoing with the first dose of Temferon administered in July 2019.

Abstract
PURPOSE Patients with type 2 diabetes (T2DM) have increased fracture risk. Osteopontin (OPN) is a protein involved in bone remodeling and inflammation. The aim of this study was to evaluate the association of OPN with fracture prevalence and with metabolic parameters in post-menopausal women with T2DM. METHODS Sixty-four post-menopausal women with T2DM (age 67.0 ± 7.8 years, diabetes duration 8.9 ± 6.7 years), enrolled in a previous study, were followed up (3.6 ± 0.9 years). Previous fragility fractures were recorded. The FRAX score (without BMD) was calculated and biochemical parameters (plasma glucose, HbA1c, lipid profile and renal function) were assessed. Serum 25OH-vitamin D, calcium, PTH and OPN were evaluated at baseline. The association between OPN and fracture prevalence at baseline was evaluated by a logistic model. RESULTS OPN levels were higher in patients with previous fractures (n.25) than in patients without previous fractures at baseline (n.39) (p = 0.006). The odds of having fractures at baseline increased by 6.7 (1.9-31.4, 95% CI, p = 0.007) for each increase of 1 ng/ml in OPN levels, after adjustment for vitamin D and HbA1c levels. Fracture incidence was 4.7%. Higher OPN associated with a decrease in HDL-cholesterol (p = 0.048), after adjustment for age, basal HDL-cholesterol, basal and follow-up HbA1c and follow-up duration. 25OH-vitamin D associated with an increase in FRAX-estimated probability of hip fracture at follow-up (p = 0.029), after adjustment for age, 25OH-vitamin D and time. CONCLUSIONS In post-menopausal women with T2DM, OPN might be a useful marker of fracture and worse lipid profile.

Abstract
OBJECTIVE To determine the prevalence and correlates of subclinical myocardial inflammation in patients with rheumatoid arthritis (RA). METHODS RA patients (n = 119) without known cardiovascular disease underwent cardiac 18-fluorodeoxyglucose (FDG) positron emission tomography with computed tomography (PET-CT). Myocardial FDG uptake was assessed visually and measured quantitatively as the standardized uptake value (SUV). Multivariable linear regression was used to assess the associations of patient characteristics with myocardial SUVs. A subset of RA patients who had to escalate their disease-modifying antirheumatic drug (DMARD) therapy (n = 8) underwent a second FDG PET-CT scan after 6 months, to assess treatment-associated changes in myocardial FDG uptake. RESULTS Visually assessed FDG uptake was observed in 46 (39%) of the 119 RA patients, and 21 patients (18%) had abnormal quantitatively assessed myocardial FDG uptake (i.e., mean of the mean SUV [SUVmean ] ≥3.10 units; defined as 2 SD above the value in a reference group of 27 non-RA subjects). The SUVmean was 31% higher in patients with a Clinical Disease Activity Index (CDAI) score of ≥10 (moderate-to-high disease activity) as compared with those with lower CDAI scores (low disease activity or remission) (P = 0.005), after adjustment for potential confounders. The adjusted SUVmean was 26% lower among those treated with a non-tumor necrosis factor-targeted biologic agent compared with those treated with conventional (nonbiologic) DMARDs (P = 0.029). In the longitudinal substudy, the myocardial SUVmean decreased from 4.50 units to 2.30 units over 6 months, which paralleled the decrease in the mean CDAI from a score of 23 to a score of 12. CONCLUSION Subclinical myocardial inflammation is frequent in patients with RA, is associated with RA disease activity, and may decrease with RA therapy. Future longitudinal studies will be required to assess whether reduction in myocardial inflammation will reduce heart failure risk in RA.

Abstract
Background Workers in pathology and anatomy laboratories may be exposed to formaldehyde. An evaluation of the early effects of this substance is, therefore, paramount. This preliminary study was conducted to evaluate if nasal cytology could be used as a tool to detect changes in nasal mucosa in workers exposed to formaldehyde. Aims To assess whether nasal cytology was able to reveal any alteration of nasal mucosa in workers exposed to formaldehyde compared to unexposed subjects, and to ascertain whether a specific pattern of alterations correlated with years of exposure in order to evaluate long-term occupational exposure effects. Methods The study included a group of workers exposed to formaldehyde and a group of non-exposed workers. All subjects underwent clinical examination, followed by nasal cytology. Pathological indices from each rhinocytograms were compared between the two groups. Results Nasal cytology revealed a chronic inflammatory non-allergic condition in the exposed group. Qualitative analysis of data distribution of neutrophils and mucous-secreting/ciliated cells ratio showed data clustering with a cut-off set at 15 years of exposure. The mean formaldehyde concentrations ranged from <0.04 to 0.15 parts per million (ppm). The maximum levels of formaldehyde concentrations ranged from 0.2 to 0.67 ppm. Conclusions Our data indicate that nasal cytology may be a promising tool for the health surveillance of workers exposed to formaldehyde and may also represent a useful research tool for the study of the health effects of other chemicals irritants for the upper airways.

Abstract
The combined harmful effects of cigarette smoking and hyperglycemia can accelerate vascular damage in patients with diabetes who smoke, as is well known. Can smoking cause diabetes? What are the effects of smoking on macro and microvascular complications? Now growing evidence indicates that regular smokers are at risk of developing incident diabetes. Since the prevalence rates of smoking in patients with diabetes are relatively similar to those of the general population, it is essential to address the main modifiable risk factor of smoking to prevent the onset of diabetes and delay the development of its complications. Quitting smoking shows clear benefits in terms of reducing or slowing the risk of cardiovascular morbidity and mortality in people with diabetes. Does quitting smoking decrease the incidence of diabetes and its progression? What are the effects of quitting smoking on complications? The current evidence does not seem to unequivocally suggest a positive role for quitting in patients with diabetes. Quitting smoking has also been shown to have a negative impact on body weight, glycemic control and subsequent increased risk of new-onset diabetes. Moreover, its role on microvascular complications of the disease is unclear. What are the current smoking cessation treatments, and which ones are better for patients with diabetes? Stopping smoking may be of value for diabetes prevention and management of the disease and its macrovascular and microvascular complications. Unfortunately, achieving long-lasting abstinence is not easy and novel approaches for managing these patients are needed. This narrative review examines the evidence on the impact of smoking and smoking cessation in patients with diabetes and particularly in type 2 diabetes mellitus and its complications. In addition, management options and potential future directions will be discussed.

Abstract
BACKGROUND AND PURPOSE Deep gray matter involvement is a consistent feature in multiple sclerosis. The aim of this study was to evaluate the relationship between different deep gray matter alterations and the development of subcortical atrophy, as well as to investigate the possible different substrates of volume loss between phenotypes. MATERIALS AND METHODS Seventy-seven patients with MS (52 with relapsing-remitting and 25 with progressive MS) and 41 healthy controls were enrolled in this cross-sectional study. MR imaging investigation included volumetric, DTI, PWI and Quantitative Susceptibility Mapping analyses. Deep gray matter structures were automatically segmented to obtain volumes and mean values for each MR imaging metric in the thalamus, caudate, putamen, and globus pallidus. Between-group differences were probed by ANCOVA analyses, while the contribution of different MR imaging metrics to deep gray matter atrophy was investigated via hierarchic multiple linear regression models. RESULTS Patients with MS showed a multifaceted involvement of the thalamus and basal ganglia, with significant atrophy of all deep gray matter structures (P < .001). In the relapsing-remitting MS group, WM lesion burden proved to be the main contributor to volume loss for all deep gray matter structures (P ≤ .006), with a minor role of local microstructural damage, which, in turn, was the main determinant of deep gray matter atrophy in patients with progressive MS (P ≤ .01), coupled with thalamic susceptibility changes (P = .05). CONCLUSIONS Our study confirms the diffuse involvement of deep gray matter in MS, demonstrating a different behavior between MS phenotypes, with subcortical GM atrophy mainly determined by global WM lesion burden in patients with relapsing-remitting MS, while local microstructural damage and susceptibility changes mainly accounted for the development of deep gray matter volume loss in patients with progressive MS.

Abstract
PURPOSE To diagnose cholesteatoma when it is not visible through tympanic perforation, imaging techniques are necessary. Recently, the combination of computed tomography and magnetic resonance imaging has proven effective to diagnose middle ear cholesteatoma. In particular, diffusion weighted images have integrated the conventional imaging for the qualitative assessment of cholesteatoma. Accordingly, the aim of this study was to obtain a quantitative analysis of cholesteatoma calculating the apparent diffusion coefficient value. So, we investigated whether it could differentiate cholesteatoma from other inflammatory tissues both in a preoperative and in a postoperative study. METHODS This study included 109 patients with clinical suspicion of primary or residual/recurrent cholesteatoma. All patients underwent preoperative computed tomography and magnetic resonance imaging with diffusion sequences before primary or second-look surgery to calculate the apparent diffusion coefficient value. RESULTS We found that the apparent diffusion coefficient values of cholesteatoma were significantly lower than those of non cholesteatoma. In particular, the apparent diffusion coefficient median value of the cholesteatoma group (0.84 × 10- 3 mm2/s) differed from the inflammatory granulation tissue (2.21 × 10- 3 mm2/s) group (p < 2.2 × 10- 16). Furthermore, we modeled the probability of cholesteatoma by means of a logistic regression and we determined an optimal cut-off probability value of ~ 0.86 (specificity = 1.0, sensitivity = 0.97), corresponding to an apparent diffusion coefficient cut-off value of 1.37 × 10- 3 mm2/s. CONCLUSIONS Our study has demonstrated that apparent diffusion coefficient values constitute a valuable quantitative parameter for preoperative differentiation of cholesteatomas from other middle ear inflammatory diseases and for postoperative diagnosis of recurrent/residual cholesteatomas.

Abstract
AIMS The aims of the present study were to assess the safety, pharmacokinetics (PK) and pharmacodynamics (PD) of BMS-962212, a first-in-class factor XIa inhibitor, in Japanese and non-Japanese healthy subjects. METHODS This was a randomized, placebo-controlled, double-blind, sequential, ascending-dose study of 2-h (part A) and 5-day (part B) intravenous (IV) infusions of BMS-962212. Part A used four doses (1.5, 4, 10 and 25 mg h-1 ) of BMS-962212 or placebo in a 6:2 ratio per dose. Part B used four doses (1, 3, 9 and 20 mg h-1 ) enrolling Japanese (n = 4 active, n = 1 placebo) and non-Japanese (n = 4 active, n = 1 placebo) subjects per dose. The PK, PD, safety and tolerability were assessed throughout the study. RESULTS BMS-962212 was well tolerated; there were no signs of bleeding, and adverse events were mild. In parts A and B, BMS-962212 demonstrated dose proportionality. The mean half-life in parts A and B ranged from 2.04 to 4.94 h and 6.22 to 8.65 h, respectively. Exposure-dependent changes were observed in the PD parameters, activated partial thromboplastin time (aPTT) and factor XI clotting activity (FXI:C). The maximum mean aPTT and FXI:C change from baseline at 20 mg h-1 in part B was 92% and 90%, respectively. No difference was observed in weight-corrected steady-state concentrations, aPTT or FXI:C between Japanese and non-Japanese subjects (P > 0.05). CONCLUSION BMS-962212 has tolerability, PK and PD properties suitable for investigational use as an acute antithrombotic agent in Japanese or non-Japanese subjects.

Abstract
BACKGROUND AND AIMS Type I hyperlipoproteinemia, also known as familial chylomicronemia syndrome (FCS), is a rare autosomal recessive disorder caused by variants in LPL, APOC2, APOA5, LMF1 or GPIHBP1 genes. The aim of this study was to identify novel variants in the LPL gene causing lipoprotein lipase deficiency and to understand the molecular mechanisms. METHODS AND RESULTS A total of 3 individuals with severe hypertriglyceridemia and recurrent pancreatitis were selected from the Lipid Clinic at Sahlgrenska University Hospital and LPL was sequenced. In vitro experiments were performed in human embryonic kidney 293T/17 (HEK293T/17) cells transiently transfected with wild type or mutant LPL plasmids. Cell lysates and media were used to analyze LPL synthesis and secretion. Media were used to measure LPL activity. Patient 1 was compound heterozygous for three known variants: c.337T > C (W113R), c.644G > A (G215E) and c.1211T > G (M404R); patient 2 was heterozygous for the known variant c.658A > C (S220R) while patient 3 was homozygous for a novel variant in the exon 5 c.679G > T (V227F). All the LPL variants identified were loss-of-function variants and resulted in a substantial reduction in the secretion of LPL protein. CONCLUSION We characterized at the molecular level three known and one novel LPL variants causing type I hyperlipoproteinemia showing that all these variants are pathogenic.

Abstract
BACKGROUND Quality of Life (QoL) is a concept used to indicate the general wellness of persons or societies. University students report a low quality of life and a worse perception of their health status, because of a situation of greater discomfort in which they live during the course of the study, especially in faculties with an important emotional burden, such as medical schools. The aim of the study was to evaluate the perceived health status of first year medical students. METHODS We conducted a cross sectional study in the time span 2005-2015, administering the questionnaire Short Form 36 (SF-36) to first-year students of the School of Medicine of the University of Siena, Italy. In addition to demographic information such as gender and the age we investigated the region of residence, marital status, employment status, and smoking habits; height and weight were required to calculate the body mass index (BMI) to evaluate a possible physical discomfort connected with the perception of health status. The data from the questionnaires were organized and processed by software Stata® SE, version 12.1. RESULTS 1,104 questionnaires were collected. Medical students reported lower SF-36 scores, compared to the Italian population of the same age. Female gender and smoking habits influence negatively the score of several scales. Body Mass Index is positively correlated with the Physical Activity, while Age is negatively correlated with Social Activities. CONCLUSIONS The perceived quality of life of the Italian medical students is lower when compared to the general population. This confirms that the condition of student implies additional problems, as other studies reports. It would be better to improve it, developing students' resilience. It would be interesting to extend this research to students of other years, from other faculties and other locations, to gain a broader view about the QoL of the Italian students.

Abstract
BACKGROUND AND PURPOSE The pulvinar sign refers to exclusive T1WI hyperintensity of the lateral pulvinar. Long considered a common sign of Fabry disease, the pulvinar sign has been reported in many pathologic conditions. The exact incidence of the pulvinar sign has never been tested in representative cohorts of patients with Fabry disease. The aim of this study was to assess the prevalence of the pulvinar sign in Fabry disease by analyzing T1WI in a large Fabry disease cohort, determining whether relaxometry changes could be detected in this region independent of the pulvinar sign positivity. MATERIALS AND METHODS We retrospectively analyzed brain MR imaging of 133 patients with Fabry disease recruited through specialized care clinics. A subgroup of 26 patients underwent a scan including 2 FLASH sequences for relaxometry that were compared with MRI scans of 34 healthy controls. RESULTS The pulvinar sign was detected in 4 of 133 patients with Fabry disease (3.0%). These 4 subjects were all adult men (4 of 53, 7.5% of the entire male population) with renal failure and under enzyme replacement therapy. When we tested for discrepancies between Fabry disease and healthy controls in quantitative susceptibility mapping and relaxometry maps, no significant difference emerged for any of the tested variables. CONCLUSIONS The pulvinar sign has a significantly lower incidence in Fabry disease than previously described. This finding, coupled with a lack of significant differences in quantitative MR imaging, allows hypothesizing that selective involvement of the pulvinar is a rare neuroradiologic sign of Fabry disease.
