Abstract
Due to its excellent properties, poly(ethylene terephthalate) (PET) is one of the most produced and consumed polymers. Among plastics, it represents the main contributor to environmental pollution. Following the circular economy model, the chemical upcycling of PET reduces the amount of waste generated and transforms it into high-value products. The depolymerization of poly(ethylene terephthalate) into oligomers or monomers leads to forming a library of reactive molecules involved in different polymerization processes to obtain compounds with improved properties. Herein, several β-hydroxy amines were synthesized and used for the chemical recycling of water bottle waste by an environmental benefit aminolysis process to get very useful new terephthalamide diol monomers. The recycled diol monomers were subsequently exploited to synthesize poly(urethane acrylates) (PUAs) UV-curable coatings, and their chemical, thermal and mechanical characterizations were performed. The results show the great potential of the developed synthesis protocols to obtain PUAs with final properties that can be modulated to meet the requirements of different applications.

Abstract
PURPOSE OF THE RESEARCH transbronchial lung cryobiopsy has been recently accepted as a valid and less invasive alternative to surgical lung biopsy. The purpose of this randomized controlled study was to evaluate, for the first time, the quality and safety of biopsy specimens obtained by using the new disposable 1.7-mm cryoprobe compared with the standard re-usable 1.9 mm cryoprobe in the diagnosis of diffuse parenchymal lung diseases. METHODS 60 consecutive patients were prospectively enrolled and randomly assigned to two different groups: 1.9 mm (group A) and 1.7 mm (group B); primary endpoints were pathological and multidisciplinary diagnostic yield, sample size and complication rate. PRINCIPAL RESULTS the pathological diagnostic yield of cryobiopsy was 100% in group A and 93.3% in group B (p = 0.718); cryobiopsy median diameter was 6.8 mm in group A and 6.7 mm in group B (p = 0,5241). Pneumothorax occurred in 9 patients in group A and 10 in group B (p = 0.951); mild-to-moderate bleeding in 7 cases and 9 cases in group A and B respectively (p = 0.559). No death or severe adverse events were observed. CONCLUSIONS there was no statistically significant difference between the two groups, regarding diagnostic yield, adverse events and sampling adequacy.

Abstract
A poly(urethane-acrylate) polymer (PUA) was synthesized, and a sufficiently high molecular weight starting from urethane-acrylate oligomer (UAO) was obtained. PUA was then loaded with two types of powdered ligno-cellulosic waste, namely from licorice root and palm leaf, in amounts of 1, 5 and 10%, and the obtained composites were chemically and mechanically characterized. FTIR analysis of final PUA synthesized used for the composite production confirmed the new bonds formed during the polymerization process. The degradation temperatures of the two types of waste used were in line with what observed in most common natural fibers with an onset at 270 °C for licorice waste, and at 290 °C for palm leaf one. The former was more abundant in cellulose (44% vs. 12% lignin), whilst the latter was richer in lignin (30% vs. 26% cellulose). In the composites, only a limited reduction of degradation temperature was observed for palm leaf waste addition and some dispersion issues are observed for licorice root, leading to fluctuating results. Tensile performance of the composites indicates some reduction with respect to the pure polymer in terms of tensile strength, though stabilizing between data with 5 and 10% filler. In contrast, Shore A hardness of both composites slightly increases with higher filler content, while in stiffness-driven applications licorice-based composites showed potential due to an increase up to 50% compared to neat PUA. In general terms, the fracture surfaces tend to become rougher with filler introduction, which indicates the need for optimizing interfacial adhesion.

Abstract
AIMS The introduction of immunotherapy for patients with head and neck squamous cell carcinoma (HNSCC) raises the need for harmonisation between different types of antibody and immunohistochemistry platform for evaluating the expression of PD-L1 by use of the combined positive score (CPS) in this tumour. The aim of this study was to compare the expression of PD-L1 as determined with the CPS and two widely used assays (the 22C3 PharmDx assay and the SP263 assay) in a cohort of HNSCCs. METHODS AND RESULTS We analysed 43 whole sections of HNSCC with two different anti-PD-L1 antibodies, 22C3 and SP263. The results, expressed as the CPS, were evaluated by 10 trained pathologists and statistical analyses were performed. We found a very similar results for PD-L1 expression between the 22C3 PharmDx assay and the SP263 assay in our cohort, and a strong and significant correlation between the two assays for all specimens (P < 0.0001). The interobserver reliability among pathologists for the continuous scores of CPS with the intraclass correlation coefficient and the correlation between the two assays were both good. Moreover, the rate of agreement between assays was high at all cut-offs and was best for the most relevant cut-off of CPS ≥ 1, and the kappa values were always in the range of almost perfect. CONCLUSIONS Two different assays (the 22C3 PharmDx assay and SP263 assay) for PD-L1 in HNSCC showed high agreement. These data suggest that these two assays are interchangeable in the selection of patients with HNSCC for immunotherapy.

Abstract
INTRODUCTION SANT of the spleen is a benign lesion that does not recur after splenectomy with unknown etiology. PRESENTATION OF THE CASE We report a case of sclerosing angiomatoid nodular transformation (SANT) of the spleen mimicking a splenic abscess in a patient with imaging studies that failed to differentiate this lesion from other splenic lesions. DISCUSSION SANT of the spleen is a rare condition, with only less than 100 cases reported in the literature. Clinically, SANT is only a kind of described pathological diagnostic conception. As in our case, these splenic lesions are often incidental findings on imaging studies performed for other reasons. CONCLUSION The patient was treated with splenectomy, which has proved to be both diagnostic and therapeutic. Although histology can lead to the diagnosis of vascular tumor, immunohistochemistry is the only way to confirm the diagnosis.

Abstract
The levels of α1-antitrypsin, transferrin, alkaline phosphatase, phosphohexoseisomerase and γ-glutamyltransferase were measured in 32 samples of breast cyst fluid, and a wide range of values was obtained. The levels observed in some samples for these parameters, being similar to those of normal serum, might suggest a mechanism of plasma exudation for the formation of breast cyst fluid. Nevertheless, a comparison with the maximum normal serum reference value revealed very high levels of γ-glutamyltransferase in all of the samples; about 50% also exhibited high levels of phosphohexoseisomerase. These results indicate that the formation of breast cyst fluid takes place with a specific local production, in addition to the mechanism of selective plasma exudation. Moreover, elevated transferrin levels in some cyst fluids are probably the expression of a high biosynthetic activity and could be diagnostically useful in the course of breast gross cystic disease. The importance of these observations from the point of view of diagnostic and prognostic trends are discussed.

Abstract
The hippocampus is thought to initiate systems-wide mnemonic processes through the reactivation of previously acquired spatial and episodic memory traces, which can recruit the entorhinal cortex as a first stage of memory redistribution to other brain areas. Hippocampal reactivation occurs during sharp wave-ripples, in which synchronous network firing encodes sequences of places. We investigated the coordination of this replay by recording assembly activity simultaneously in the CA1 region of the hippocampus and superficial layers of the medial entorhinal cortex. We found that entorhinal cell assemblies can replay trajectories independently of the hippocampus and sharp wave-ripples. This suggests that the hippocampus is not the sole initiator of spatial and episodic memory trace reactivation. Memory systems involved in these processes may include nonhierarchical, parallel components.

Abstract
PURPOSES The optimal treatment of N₂ non-small cell lung cancer (NSCLC) in older patients is still debate and represent an important treatment and ethical problem. PATIENTS AND METHODS Between January 2000 to December 2010, 273 older patients underwent lung resection for (NSCLC). RESULTS The overall-operative mortality was 9.5%. Risk factors for in-hospital mortality were pneumonectomy and poli-vasculopathy. One, 3 and 5-year survival were 73%, 23% and 16% respectively. CONCLUSIONS In potentially operable older patients with NSCLC we need to make every effort to exclude N₂ involvement because very poor long-term survival. Pneumonectomy in older patients gains prohibitive in-hospital mortality.

Abstract
PURPOSE Although honeycombing is one of the key features for the diagnosis of idiopathic pulmonary fibrosis (IPF), its origin and evolution are still poorly understood. The aim of our study was to analyse the natural history of honeycombing in patients treated with single-lung transplantation. MATERIALS AND METHODS We considered seven patients who underwent single-lung transplantation; two of them (28.6%) were excluded from our analysis because they died in the posttransplantation period, whereas the remaining five (71.4%) were evaluated with computed tomography (CT) over 67.6±38.56 months. Each CT scan was assessed for disease extension and cyst size (visual score and size of target cysts); CT scans acquired after 2006 were also assessed for native lung volume. RESULTS All patients showed disease progression (with a concurrent reduction in lung volume in two, 40%) and a progression of honeycombing, with increased number and size of cysts in four (80%). We observed dimensional changes in all target cysts (enlargement or reduction); three patients (60%) also had radiological evidence of complications, such as spontaneous rupture with pneumothorax and development of mycetomas within the cysts. CONCLUSIONS Honeycombing is a dynamic process in which the overall trend is represented by a dimensional increase in cystic pattern; however, single cysts may have a different evolution (enlargement, reduction or complications). This behaviour could be explained by the variety of the pathogenetic processes underlying honeycombing, with cysts that may present abnormal communication with the airway, including the development of a check-valve mechanism.

Abstract
The incidence of gastrointestinal complications in renal transplant recipients is relatively high while about 10% is related to acute abdomen. Data concerning gastrointestinal (GI) complications were reported in literature mainly from referral center studies. A multicenter retrospectively survey was performed in Lazio, Italy, in order to evaluate the incidence of acute abdomen in renal transplant recipients observed to the emergency departments of not referral transplantation centers. Clinical and demographic findings regarding 14 patients who experienced acute abdomen between February 2005 and Dicember 2008 have been collected. The following data was investigated: etiology, diagnostic workup, duration of symptoms, elapsed time between admission and emergency operation if performed, morbility and mortality. The severity of disease at presentation was assessed by mean of the Acute Physiology and Chronic Health Evaluation score (APACHE II). Acute abdomen was due to pancreatitis in three patients (23.1%); to cholecystitis in three (23.1%); to acute diverticolitis with colon perforation in two patients (15.4%); to acute appendicitis in two (15.4%) and to intestinal obstruction in 2 patients (15.4%). Small bowel perforation was observed in two patients (15.4%) which one case, upon pathological examination, showed malignant lymphoma. The mean APACHE II score was 14.0 ± 5.9. Ten patients (71.4%) were submitted to surgery. Overall mortality and morbidity were 35% and 42% respectively. Statistical analysis showed admission APACHE II score (p<0.01), duration of symptoms (p<0.05), and total time elapsed between the onset of symptoms and treatment (p<0.04) as factors significantly related to mortality.

Abstract
BACKGROUND Neuropsychiatric symptoms (NPS) affect almost all patients with dementia and are a major focus of study and treatment. Accurate assessment of NPS through valid, sensitive and reliable measures is crucial. Although current NPS measures have many strengths, they also have some limitations (e.g. acquisition of data is limited to informants or caregivers as respondents, limited depth of items specific to moderate dementia). Therefore, we developed a revised version of the NPI, known as the NPI-C. The NPI-C includes expanded domains and items, and a clinician-rating methodology. This study evaluated the reliability and convergent validity of the NPI-C at ten international sites (seven languages). METHODS Face validity for 78 new items was obtained through a Delphi panel. A total of 128 dyads (caregivers/patients) from three severity categories of dementia (mild = 58, moderate = 49, severe = 21) were interviewed separately by two trained raters using two rating methods: the original NPI interview and a clinician-rated method. Rater 1 also administered four additional, established measures: the Apathy Evaluation Scale, the Brief Psychiatric Rating Scale, the Cohen-Mansfield Agitation Index, and the Cornell Scale for Depression in Dementia. Intraclass correlations were used to determine inter-rater reliability. Pearson correlations between the four relevant NPI-C domains and their corresponding outside measures were used for convergent validity. RESULTS Inter-rater reliability was strong for most items. Convergent validity was moderate (apathy and agitation) to strong (hallucinations and delusions; agitation and aberrant vocalization; and depression) for clinician ratings in NPI-C domains. CONCLUSION Overall, the NPI-C shows promise as a versatile tool which can accurately measure NPS and which uses a uniform scale system to facilitate data comparisons across studies.

Abstract
BACKGROUND The aim of our study was to test the aerostatic validity of a cyan-acrylic glue (Glubran 2), applied by means of a spray catheter, on an experimental pig model. MATERIALS AND METHODS 15 young pigs were divided into three study groups of 5 based on surgical techniques: (1) atypical pulmonary resection with mechanical suturing and reinforcement with continuous suturing; (2) resection of the pulmonary parenchyma with a cold scalpel, followed by local application of Glubran 2; (3) atypical pulmonary resection with mechanical suturing followed by application of Glubran 2. RESULTS The mean aerostasis time was calculated at 3.5 +/- 1.26 s. The histopathological analysis did not show any particular differences when comparing the effects of the treatments carried out with Glubran 2 spray glue and the standard treatments. No statistically significant differences were recorded in the short- and medium-term survival of pigs treated with Glubran 2 compared with the respective control groups. CONCLUSIONS The application of Glubran 2 spray on wounds caused by pulmonary resections in pigs proved to have a rapid and effective influence for the purposes of aerostasis without significant differences in air losses and survivals.

Abstract
BACKGROUND AND AIMS Issues on colonoscopy quality are crucial to reduce the advanced neoplasia miss rate of colonoscopy. Recently, a >6-min withdrawal time has been recommended. However, the relative prevalence of polyp detected during insertion and withdrawal phases of colonoscopy is unknown. Therefore, we designed this prospective, endoscopic study. MATERIALS AND METHODS Three hundred and sixty-eight patients with 396 adenomas were selected from a consecutive colonoscopic series of 1,205 cases. Detection rates of adenomas, advanced adenomas, and cancer according to withdrawal and insertion phases of colonoscopy, also subgrouping polyps for size and location, were compared. RESULTS Thirty-two (74%) advanced adenomas and 21 (95%) cancers were detected during the insertion, being only 11 (26%) and one (5%) identified during withdrawal, respectively. This was mainly due to a higher detection of >10 mm polyps during insertion than during withdrawal (75% versus 25%). CONCLUSIONS Most advanced neoplasia are detected during the insertion. Although withdrawal time has been shown to be important, the scope insertion phase related to polyp detection should be specifically addressed.

Abstract
INTRODUCTION Complex relations between brain and psychopathology have attracted the interest of researchers, aiming to clarify the neurobiological mechanisms of depression in Parkinson's disease, obviously in addiction to mental features. AIMS The association of motor impairment and decline of personal autonomy with severity of depressive symptoms was the hypothesis of the present study. Aiming to check this hypothesis, the objective of this study consisted in investigating relationships between the severity of depressive symptoms and motor characteristics of Parkinson's disease. PATIENTS AND METHODS Thirty patients (53 to 80 year-old) with medical diagnosis of idiopathic Parkinson's disease in initial clinic stages were studied. The Unified Parkinson's Disease Rating Scale, Hoehn-Yahr Scale, and Schwab & England Scale were used to assess the clinic signs and symptoms. The depressive symptoms were identified by complete anamnesis, examination of mental condition, and the Hamilton Rating Scale for Depression and the Anxiety and Depression Scale. Statistical analysis was performed by Pearson's correlation and multiple regression analysis. RESULTS A significant correlation of severity of depression symptoms with disease stage (p < 0.02), with motor signs (p < 0.008), and with functional performance (p < 0.007) was found. CONCLUSION There was significant association between motor impairment and severity of depressive symptoms, and between depression and early disease onset or prolonged duration of Parkinson's disease.

Abstract
With the ever increasing interest in the field of osteodistraction techniques, the mandible is certainly the most studied anatomical site, both experimentally and clinically. Currently, the methods of mandibular distraction can be classified by position (intra- or extraoral), by the direction of distraction and by the site of application (toothborn, boneborn or hybrid fixation). To guarantee good results from the osteodistraction procedure, it is fundamental to have an accurate preoperative plan considering the correct classification and evaluation of the patient combined with a valid project regarding the direction of the distraction vector. One of the most important aspects to consider is the orientation of the distractor, especially if the defect to be corrected is three-dimensional. Regarding the correct planning of the operation, knowing the secondary effects of the distraction on the soft tissues, muscles and nerves, the temporomandibular joint and velopharyngeal functioning is of fundamental importance. It is worth considering particular situations in which osteodistraction is extremely helpful in maxillofacial surgery, for example in the construction of a neocondyle, in bone replacement during oncologic interventions, in obstructive sleep apnea correction and in hemi-mandibular reconstruction.

Abstract
BACKGROUND Although the stomach is the most frequent site of intestinal lymphomas, few data are available on both clinical endoscopic presentation of gastric lymphoma and possible differences between low-grade and high-grade lymphomas. METHODS Clinical, histological and endoscopic records of consecutive patients with primary low-grade or high-grade lymphoma diagnosed were retrieved. Symptoms were categorized as 'alarm' or 'not alarm'. The endoscopic findings were classified as 'normal' or 'abnormal'. RESULTS Overall, 144 patients with primary gastric lymphoma were detected, including 74 low-grade and 70 high-grade lymphoma. Alarm symptoms, particularly persistent vomiting and weight loss, were more frequently present in patients with high-grade lymphoma than in those with low-grade lymphoma (54% vs. 28%; P = 0.002). Low-grade lymphomas presented as 'normal' appearing mucosa (20% vs. 0%; P = 0.0004) or petechial haemorrhage in the fundus (9% vs. 0%; P = 0.02) more frequently than high-grade lymphomas, being also more often confined to the antrum (47% vs. 27%, P = 0.03) and associated with Helicobacter pylori infection (88% vs. 52%, P < 0.0001). On the contrary, high-grade lymphomas presented more commonly as ulcerative type (70% vs. 52%; P = 0.03), being also more frequently diagnosed in stage >I when compared with low-grade lymphomas (70% vs. 21%, P < 0.0001). CONCLUSIONS The overall prevalence of alarm symptoms is quite low and may be absent in more than 70% of patients with low-grade lymphoma.

Abstract
BACKGROUND Helicobacter pylori clarithromycin resistance is increasing worldwide and different mutations are involved in its mechanisms. Recently, molecular methods have been proposed to assess these mutations. AIM To assess prevalence of primary clarithromycin resistance in two Italian areas, and the distribution of involved mutations, by using a novel method for real-time polymerase chain reaction. METHODS Two hundred and thirty-two H. pylori-positive patients undergoing oesophagogastroduodenoscopy in two Italian towns (Rome, centre Italy; Foggia, south Italy) were enrolled. Helicobacter pylori infection was detected by histology, rapid urease and urea breath tests. Clarithromycin resistance was assessed by TaqMan real-time polymerase chain reaction on paraffin-embedded antral biopsies. Results Primary clarithromycin resistance was detected in 62 (26.7%) patients. Its prevalence did not differ between the two areas (31.5%, centre vs. 23.3%, south; P=0.17) and between non-ulcer dyspepsia and peptic ulcer patients (28.4% vs. 20.7%, P=0.2). The A2143G point mutation was detected in 35 (56.4%) patients, A2142G in 14 (22.6%), A2142C in eight (12.9%), whilst a double mutation (A2143G plus A2142C or A2142G) was present in the remaining five (8.1%) cases. CONCLUSIONS Our study found that primary clarithromycin resistance is highly prevalent in both central and southern Italy, and that A2143G is the most frequent point mutation involved in these areas.

Abstract
BACKGROUND Three point mutations (A2143G, A2142G, and A2142C) have been involved in Helicobacter pylori clarithromycin resistance. OBJECTIVE To compare the eradication rates among the different point mutations and the efficacy of triple therapy and a sequential regimen according to genotypic resistance. DESIGN Post hoc subgroup study from a multicenter, randomized trial. SETTING Two hospitals in central and southern Italy between January and December 2001. PATIENTS 156 patients with H. pylori infection. MEASUREMENTS Real-time polymerase chain reaction for assessing clarithromycin resistance; histology, rapid urease test, and 13C-urea breath test at entry and after 4 to 6 weeks. INTERVENTION 7-day triple therapy (20 mg of rabeprazole, 500 mg of clarithromycin, and 1 g of amoxicillin) in 75 patients or a 10-day sequential regimen (20 mg of rabeprazole plus 1 g of amoxicillin for 5 days and 20 mg of rabeprazole, 500 mg of clarithromycin, and 500 mg of tinidazole for the remaining 5 days) in 81 patients. All drugs were given twice daily. RESULTS Helicobacter pylori infection was eradicated in 11 of 23 patients (48%) with the A2143G mutation and in 14 of 15 patients (93%) with either A2142G or A2142C strains (difference, 45 percentage points [95% CI, 15 to 65 percentage points]; P = 0.004). The sequential regimen achieved a higher cure rate than triple therapy in A2143G mutate strains (difference, 49 percentage points [CI, 8 to 72 percentage points]; P = 0.024). LIMITATIONS The post hoc substudy design may require further confirmation. Other limitations are the accessibility to the tool and the cost of investigations (70 euros per patient). CONCLUSIONS The A2143G mutation seemed to be associated with a very low eradication rate. The sequential regimen achieved a higher cure rate than standard therapy even in patients with these strains.

Abstract
In the specific field of maxillofacial surgery, the use of osseous distraction is always more and more helpful not only in the rehabilitation of malformation pathologies, but also in the clinical situations that require bone deficit correction resulting from traumatic events and postsurgical effects, for example oncologic surgery. The reason for this versatility in the distraction protocols is, undoubtedly, due to the fact that, at present, they are valid surgical methods in alternative to or supporting maxillofacial surgery, since they are feasible from a very early age and they obtain a level of distraction that is often higher than with orthopedic devices or conventional surgery. There are multiple indications for osteodistraction and they range from cases of hyper- or hypodevelopment of the maxilla and mandible, of both their anteroposterior and transverse components, to complex syndromes such as cleft lip and palate. Even the clinical distraction of the upper and middle thirds of the cranium, through a coronal craniotomy, has been shown to be a safe surgical procedure and it allows, for example, the successful rehabilitation of adult patients suffering from hemifacial microsomia or craniosynostosis. With the continuous and constant evolution of the integration of osteodistraction principles in the rehabilitation of the craniofacial region, an ever-more effective interdisciplinary relationship between orthodontics and osteodistraction has been seen with growing interest. More often treatment plans are programmed in which the orthodontic and osteodistractive phases are integrated and complete each other, each supporting the other. Scientific and clinical progress achieved in this field in recent years, allows more and more refined therapeutic solutions to be programmed, permitting craniofacial operations and to repair an ankylotic dental arch or reposition osteointegrated implants to the most convenient bone sites.

Abstract
BACKGROUND Although E-cadherins have been involved in gastric carcinogenesis, their role in precancerous lesions, such as intestinal metaplasia, is still unclear. This study aimed to assess the role of both intestinal metaplasia and H. pylori infection on E-cadherin expression in gastric mucosa. PATIENTS AND METHODS Twenty-one consecutive patients with intestinal metaplasia were enrolled to assess E-cadherin expression in metaplastic areas. Twenty further patients without intestinal metaplasia, with and without H. pylori, were enrolled to evaluate the role of the infection on E-cadherin expression. All patients underwent upper endoscopy and gastric biopsies were taken for histological and immunohistochemical assessment. RESULTS A substantial reduction of E-cadherin expression in metaplastic areas was observed in 14 (67%) of the 21 patients, similarly in H. pylori-infected and uninfected patients (64% vs 71%, p=0.3). In the group without intestinal metaplasia, no reduction in E-cadherin expression was detected either in infected patients or in those without H. pylori infection. CONCLUSION The data showed that intestinal metaplasia is associated with E-cadherin down-regulation, whereas H. pylori infection does not seem to play a direct role in this process.
