Abstract
Plant pathogens cause significant losses to agricultural yields and increasingly threaten food security1, ecosystem integrity and societies in general2-5. Xylella fastidiosa is one of the most dangerous plant bacteria worldwide, causing several diseases with profound impacts on agriculture and the environment6. Primarily occurring in the Americas, its recent discovery in Asia and Europe demonstrates that X. fastidiosa's geographic range has broadened considerably, positioning it as a reemerging global threat that has caused socioeconomic and cultural damage7,8. X. fastidiosa can infect more than 350 plant species worldwide9, and early detection is critical for its eradication8. In this article, we show that changes in plant functional traits retrieved from airborne imaging spectroscopy and thermography can reveal X. fastidiosa infection in olive trees before symptoms are visible. We obtained accuracies of disease detection, confirmed by quantitative polymerase chain reaction, exceeding 80% when high-resolution fluorescence quantified by three-dimensional simulations and thermal stress indicators were coupled with photosynthetic traits sensitive to rapid pigment dynamics and degradation. Moreover, we found that the visually asymptomatic trees originally scored as affected by spectral plant-trait alterations, developed X. fastidiosa symptoms at almost double the rate of the asymptomatic trees classified as not affected by remote sensing. We demonstrate that spectral plant-trait alterations caused by X. fastidiosa infection are detectable previsually at the landscape scale, a critical requirement to help eradicate some of the most devastating plant diseases worldwide.

Abstract
With the aim of verifying the in vivo applicability of local hyperthermia combined with chemotherapy, 13 patients with superficial metastases from different histologic types of carcinoma, mostly from head and neck cancer, were entered in a pilot study. The chemotherapeutic regimen was cisplatinum, 20 mg/m2/dx5 days, bleomycin, 10 mg/m2 on days 8 and 12, methotrexate, 100 mg/m2 on day 15, followed after 24 by folinic acid. Hyperthermia, using a microwave apparatus, and chemotherapy were delivered simultaneously. Objective remissions were achieved in 54% of patients, within the hyperthermia field (1 CR and 6 PR). No serious toxicity was noted. Methotrexate distribution after local hyperthermia was evaluated in 8 patients. Response duration was not gratifying, except for patients successively treated with radiation. In conclusion, the combination of chemotherapy plus local hyperthermia deserves subsequent evaluation as part of adjunctive programs.

Abstract
In autumn 2013, the presence of Xylella fastidiosa, a xylem-limited Gram-negative bacterium, was detected in olive stands of an area of the Ionian coast of the Salento peninsula (Apulia, southern Italy), that were severely affected by a disease denoted olive quick decline syndrome (OQDS). Studies were carried out for determining the involvement of this bacterium in the genesis of OQDS and of the leaf scorching shown by a number of naturally infected plants other than olive. Isolation in axenic culture was attempted and assays were carried out for determining its pathogenicity to olive, oleander and myrtle-leaf milkwort. The bacterium was readily detected by quantitative polymerase chain reaction (qPCR) in all diseased olive trees sampled in different and geographically separated infection foci, and culturing of 51 isolates, each from a distinct OQDS focus, was accomplished. Needle-inoculation experiments under different environmental conditions proved that the Salentinian isolate De Donno belonging to the subspecies pauca is able to multiply and systemically invade artificially inoculated hosts, reproducing symptoms observed in the field. Bacterial colonization occurred in prick-inoculated olives of all tested cultivars. However, the severity of and timing of symptoms appearance differed with the cultivar, confirming their differential reaction.

Abstract
According to the European Directive 2008/50/CE, the air quality assessment consists in the measurement of the concentration fields, and the evaluation of the mean, number of exceedances, etc. of some chemical species dangerous to human health. The measurements provided by an air quality ground-based monitoring network are the main information source but the availability of these data is often limited by several technical and operational problems. In this paper, the best linear unbiased estimator (BLUE) is proposed to validate the pollutant concentration values and to fill the gaps in the measurement of time series collected by a monitoring network. The BLUE algorithm is tested using the daily mean concentrations of particulate matter having aerodynamic diameter less than 10 μ (PM10 concentrations) measured by the air quality monitoring sensors operating in the Lazio Region in Italy. The comparison between the estimated and measured data evidences an error comparable with the measurement uncertainty. Due to its simplicity and reliability, the BLUE will be used in the routine quality test procedures of the Lazio air quality monitoring network measurements.

Abstract
BACKGROUND AND PURPOSE The superior cerebellar peduncle is damaged in progressive supranuclear palsy. However, alterations differ between progressive supranuclear palsy with Richardson syndrome and progressive supranuclear palsy-parkinsonism. In this study, we propose an automated tool for superior cerebellar peduncle integrity assessment and test its performance in patients with progressive supranuclear palsy with Richardson syndrome, progressive supranuclear palsy-parkinsonism, Parkinson disease, and healthy controls. MATERIALS AND METHODS Structural and diffusion MRI was performed in 21 patients with progressive supranuclear palsy with Richardson syndrome, 9 with progressive supranuclear palsy-parkinsonism, 20 with Parkinson disease, and 30 healthy subjects. In a fully automated pipeline, the left and right superior cerebellar peduncles were first identified on MR imaging by using a tractography-based atlas of white matter tracts; subsequently, volume, mean diffusivity, and fractional anisotropy were extracted from superior cerebellar peduncles. These measures were compared across groups, and their discriminative power in differentiating patients was evaluated in a linear discriminant analysis. RESULTS Compared with those with Parkinson disease and controls, patients with progressive supranuclear palsy with Richardson syndrome showed alterations of all superior cerebellar peduncle metrics (decreased volume and fractional anisotropy, increased mean diffusivity). Patients with progressive supranuclear palsy-parkinsonism had smaller volumes than those with Parkinson disease and controls and lower fractional anisotropy than those with Parkinson disease. Patients with progressive supranuclear palsy with Richardson syndrome had significantly altered fractional anisotropy and mean diffusivity in the left superior cerebellar peduncle compared with those with progressive supranuclear palsy-parkinsonism. Discriminant analysis with the sole use of significant variables separated progressive supranuclear palsy-parkinsonism from progressive supranuclear palsy with Richardson syndrome with 70% accuracy and progressive supranuclear palsy-parkinsonism from Parkinson disease with 74% accuracy. CONCLUSIONS We demonstrate the feasibility of an automated approach for extracting multimodal MR imaging metrics from the superior cerebellar peduncle in healthy subjects and patients with parkinsonian. We provide evidence that structural and diffusion measures of the superior cerebellar peduncle might be valuable for computer-aided diagnosis of progressive supranuclear palsy subtypes and for differentiating patients with progressive supranuclear palsy-parkinsonism from with those with Parkinson disease.

Abstract
We present an innovative satellite-based solar UV (ultraviolet) radiation dosimeter with a mobile app interface that has been validated by exploiting both ground-based measurements and an in vivo assessment of the erythemal effects on some volunteers having controlled exposure to solar radiation. The app with this satellite-based UV dosimeter also includes other related functionalities such as the provision of safe sun exposure time updated in real-time and end exposure visual/sound alert. Both validations showed that the system has a good accuracy and reliability needed for health-related applications. This app will be launched on the market by siHealth Ltd in May 2016 under the name of "HappySun" and is available for both Android and iOS devices (more info on ). Extensive R&D activities are on-going for the further improvement of the satellite-based UV dosimeter's accuracy.

Abstract
BACKGROUND Targeted antifungal prophylaxis against Candida species or against Candida species and Aspergillus species, according to individual patient risk factors (RFs), is recommended by experts. However, recent studies have reported fluconazole is as effective as broader spectrum antifungals for preventing invasive fungal infection (IFI) after liver transplantation (LT). METHODS We performed a retrospective cohort study of all adult patients who underwent LT at our 1420-bed tertiary teaching hospital, from June 2010 to December 2014, to assess the rate and etiology of IFI within 100 days after LT, to investigate the compliance with targeted prophylaxis, and to analyze risk factors for developing IFI. RESULTS In total, 303 patients underwent LT. Patients were classified as having low (no RFs), intermediate (1 RF for invasive candidiasis [IC]), and high risk (1 RF for invasive aspergillosis [IA] or ≥2 RFs for IC) for IFI in 20%, 30%, and 50% of cases, respectively. A total of 139 patients received antifungal prophylaxis: 98 with a mold-active drug and 41 with fluconazole. Overall adherence to targeted prophylaxis was 53%. Nineteen patients (6.3%) developed IFI: 7 IC and 12 IA. Multivariate Cox regression analysis, adjusted for median model for end-stage liver disease score at LT, stratification risk group, and adherence to targeted prophylaxis, showed that graft dysfunction, renal replacement therapy, and prophylaxis with fluconazole were independent risk factors for IFI. Seven of the 9 patients who received fluconazole prophylaxis and developed IFI were classified as having high risk for IFI, and 6 developed IA. CONCLUSION Recommended stratification is accurate for predicting patients at very high risk for IFI, who should receive prophylaxis with a mold-active drug.

Abstract
Parkinson disease (PD) can be considered as a brain multisystemic disease arising from dysfunction in several neural networks. The principal aim of this study was to assess whether large-scale structural topological network changes are detectable in PD patients who have not been exposed yet to dopaminergic therapy (de novo patients). Twenty-one drug-naïve PD patients and thirty healthy controls underwent a 3T structural MRI. Next, Diffusion Tensor Imaging (DTI) and graph theoretic analyses to compute individual structural white-matter (WM) networks were combined. Centrality (degree, eigenvector centrality), segregation (clustering coefficient), and integration measures (efficiency, path length) were assessed in subject-specific structural networks. Moreover, Network-based statistic (NBS) was used to identify whether and which subnetworks were significantly different between PD and control participants. De novo PD patients showed decreased clustering coefficient and strength in specific brain regions such as putamen, pallidum, amygdala, and olfactory cortex compared with healthy controls. Moreover, NBS analyses demonstrated that two specific subnetworks of reduced connectivity characterized the WM structural organization of PD patients. In particular, several key pathways in the limbic system, basal ganglia, and sensorimotor circuits showed reduced patterns of communications when comparing PD patients to controls. This study shows that PD is characterized by a disruption in the structural connectivity of several motor and non-motor regions. These findings provide support to the presence of disconnectivity mechanisms in motor (basal ganglia) as well as in non-motor (e.g., limbic, olfactory) circuits at an early disease stage of PD.

Abstract
AIM Aim of the study was to validate the Hyaluronic acid-Chondroitin sulfate (HA-CS) as ex adiuvantibus criteria to identified patients with urgency symptoms related to interstitial cystitis/painful bladder syndrome (IC/PBS) and to obtained a population of patients with pure stress urinary incontinence. METHODS We retrospectively analysed clinical data of 17 patients with clinical suspect of IC/PBS, which received intravescical HA-CS to reduce pelvic pain and urgency symptoms waiting for surgical treatment for stress urinary incontinence. The main outcomes were reduction of urinary frequency, urgency, and bladder pain. RESULTS Compared to baseline, a significant decrease in pain, urgency and frequency were observed. Of the 17 patients, 82.3% reported resolution of pain and urge symptoms and in patients with persistence of urge symptoms the urodynamic assessment showed an overactive bladder syndrome (OAB). CONCLUSION HA-CS treatment induces an improvement in pain and urgency symptoms in patients with IC⁄PBS that referred also stress urinary incontinence. Therefore, HA-CS treatment could be use as clinical adjunctive parameter to select patients with pure stress urinary incontinence.

Abstract
The role of Grapevine Pinot gris virus (GPGV) in the etiology of grapevine leaf mottling and deformation was investigated by biological and molecular assays. A survey on different cultivars from the Trentino Region in Italy showed a widespread distribution of GPGV, which was associated with symptomatic (79%) but also with symptomless (21%) vines. Symptomatic and GPGV-infected 'Pinot gris' vines induced symptoms on grafted vines of healthy Pinot gris or 'Traminer', whereas GPGV-infected but symptomless vines did not. High-throughput sequencing of small RNA (sRNA) populations of two infected Pinot gris accessions confirmed the existence of nearly overlapping viromes in vines with or without symptoms but phylogenetic analyses of the genomes of seven GPGV isolates from Italy and the Czech and Slovak Republics clearly differentiated those infecting symptomatic vines. The involvement of Grapevine rupestris vein feathering virus (GRVFV) in the disease, which was only infecting the symptomatic vine, was ruled out by reverse-transcription polymerase chain reaction studies. Maximum likelihood and Bayesian phylogenetic analysis of two GPGV genomic regions, encompassing part of the movement protein (MP) and coat protein gene sequences and the RNA-dependent RNA polymerase domain of the replicase gene, showed that isolates from symptomatic vines form a lineage distinct from that of symptomless vines. Moreover, the presence or lack of the MP stop codon identified in viral isolates from symptomatic or symptomless vines, respectively, is likely responsible for an MP six amino acids longer in symptomless isolates.

Abstract
AIM Abnormal uterine bleeding (AUB) affects about 30% of women in childbearing age with negative impact on patient's quality of life and uterine myomas represent one of the major cause of AUB. Laparoscopic myomectomy has proven to be efficient to reduce uterine bleeding and pelvic pain, but some patients presents postsurgery menhorragia with anemia. To reduce it, the combined use of levonorgestrel releasing intrauterine system (LNG-IUS) positioned at the end of surgery, seems to produce a clinically relevant decrease in AUB with a symptomatology improvement. The aim of this study was to retrospectively evaluate if postsurgery placement of LNG-IUS improves hematological outcomes (hemoglobin and ferritin level) in woman submitted to laparoscopic myomectomy. METHODS We retrospectively collected data from 58 women who underwent laparoscopic myomectomy from September 2010 to September 2011. Twenty-six patients were treated by laparoscopic myomectomy followed by LNG-IUS positioning at the end of surgery (Experimental group) and thirty-two patients were treated by surgery alone (Control group). We compared blood hemoglobin and ferritin levels assessed preoperatively, in day one and 6, 12 and 18 months after surgery. RESULTS There was a statistically significant improvement in terms of post-surgery hemoglobin and ferritin levels at 6 month follow up (P=0.02 and P=0.002 respectively) and 12 month follow-up (P=0.001 and P=0.001, respectively) in experimental group vs. control group and a positive trend, but not statistically significant, in ferritin levels at 18 month-follow-up (P=0.1). CONCLUSION Our data suggest that combined treatment with laparoscopic myomectomy followed by LNG-IUS produces a clinically relevant improvement in hematological values.

Abstract
Ectodermal dysplasias (EDs) are a group of genetic disorders characterized by the abnormal development of the ectodermal-derived structures. X-linked hypohidrotic ectodermal dysplasia, resulting from mutations in ED1 gene, is the most common form. The main purpose of this study was to characterize the phenotype spectrum in 45 males harboring ED1 mutations. The study showed that in addition to the involvement of the major ectodermal tissues, the majority of patients also have alterations of several minor ectodermal-derived structures. Characterizing the clinical spectrum resulting from ED1 gene mutations improves diagnosis and can direct clinical care.

Abstract
An increasing body of experimental evidence demonstrates that the glutamatergic system is involved in the genesis of l-3,4-dihydroxyphenylalanine (L-DOPA)-induced dyskinesia (LID). Indeed, the N-methyl-d-aspartate (NMDA) receptor antagonist amantadine is the only anti-dyskinetic compound used in patients, albeit with limited efficacy and side effects. In this study, we investigated the anti-dyskinetic properties of memantine, a non-competitive NMDA receptor antagonist in clinical use for the treatment of dementia, in the 6-hydroxy-dopamine (6-OHDA)-lesion rat model of Parkinson's disease. For comparison, parallel experiments were also performed with amantadine. First, we investigated the acute effect of different doses of memantine (5, 10, 15 and 20mg/kg), and amantadine (10, 20, 40, 60mg/kg) on established dyskinesia induced by L-DOPA (6mg/kg plus benserazide). Results showed that both memantine and amantadine produced a significant reduction of LID. Afterward, drug-naïve and L-DOPA-primed 6-OHDA-lesioned rats were sub-chronically treated with daily injections of L-DOPA (6mg/kg plus benserazide) alone, or in combination with the effective doses of memantine, while amantadine was tested in already dyskinetic rats. Results showed that memantine significantly dampened dyskinesia in both drug-naïve and L-DOPA-primed rats, but only during the first few days of administration. In fact, the anti-dyskinetic effect of memantine was completely lost already at the fifth administration, indicating a rapid induction of tolerance. Interestingly, a 3-week washout period was not sufficient to restore the anti-dyskinetic effect of the drug. Similarly, amantadine was able to dampen already established dyskinesia only during the first day of administration. Moreover, memantine partially decreased the therapeutic effect of L-DOPA, as showed by the result of the stepping test. Finally, loss of the anti-dyskinetic effect of memantine was associated to increased synaptic GluN2A/GluN2B ratio at striatal synaptic membranes. Our results are in line with clinical observations suggesting that NMDA receptor blockade may only be transiently effective against LID in PD patients.

Abstract
Diagnosis of invasive fungal infection remains challenging. Here we report a case of early diagnosis of invasive aspergillosis in a neutropenic patient affected by acute myeloid leukaemia, achieved through the detection of Aspergillus fumigatus species-specific ribonucleic acid sequences by a sensitive multiplex real-time polymerase chain reaction-based molecular assay. Thanks to the early diagnosis, targeted therapy was promptly established and the severe fungal infection controlled, allowing the patient to subsequently receive allogeneic hematopoietic stem cell transplantation from a haploidentical donor, her only curative option. Also in this instance, targeted secondary antifungal prophylaxis with voriconazole avoided any other fungal infection afterwards. This report suggests how the implementation of molecular assays in combination with routine diagnostic procedures, can improve microbiological diagnosis in sepsis, particularly in case of fungal infection, difficult to detect with standard microbiological culture methods.

Abstract
BACKGROUND Supervised machine learning has been proposed as a revolutionary approach for identifying sensitive medical image biomarkers (or combination of them) allowing for automatic diagnosis of individual subjects. The aim of this work was to assess the feasibility of a supervised machine learning algorithm for the assisted diagnosis of patients with clinically diagnosed Parkinson's disease (PD) and Progressive Supranuclear Palsy (PSP). METHOD Morphological T1-weighted Magnetic Resonance Images (MRIs) of PD patients (28), PSP patients (28) and healthy control subjects (28) were used by a supervised machine learning algorithm based on the combination of Principal Components Analysis as feature extraction technique and on Support Vector Machines as classification algorithm. The algorithm was able to obtain voxel-based morphological biomarkers of PD and PSP. RESULTS The algorithm allowed individual diagnosis of PD versus controls, PSP versus controls and PSP versus PD with an Accuracy, Specificity and Sensitivity>90%. Voxels influencing classification between PD and PSP patients involved midbrain, pons, corpus callosum and thalamus, four critical regions known to be strongly involved in the pathophysiological mechanisms of PSP. COMPARISON WITH EXISTING METHODS Classification accuracy of individual PSP patients was consistent with previous manual morphological metrics and with other supervised machine learning application to MRI data, whereas accuracy in the detection of individual PD patients was significantly higher with our classification method. CONCLUSIONS The algorithm provides excellent discrimination of PD patients from PSP patients at an individual level, thus encouraging the application of computer-based diagnosis in clinical practice.
