Abstract
LISA [Linea Italiana per la Spettroscopia di Assorbimento X, Italian beamline for X-ray Absorption Spectroscopy (XAS)] is the Italian CRG (Collaborating Research Group) beamline at the ESRF (European Synchrotron Radiation Facility) dedicated to XAS [d'Acapito et al., J. Synchrotron Radiat. 26, 551-558 (2019)]. In this work, a methodical test of the LISA beamline in performing diffraction measurements is carried out. Synchrotron x-ray diffraction measurements would complement absorption spectroscopy techniques with the long-range characterization of the material under investigation, while XAS provides the short-range element selective information.

First-line avelumab for patients with PD-L1-positive metastatic or locally advanced urothelial cancer who are unfit for cisplatin. Ann Oncol 2022; 33:1179-1185. [PMID: 35926813 DOI: 10.1016/j.annonc.2022.07.011] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Revised: 07/19/2022] [Accepted: 07/23/2022] [Indexed: 11/01/2022] Open
Abstract
BACKGROUND Cisplatin-based chemotherapy is the most recommended treatment for metastatic urothelial cancer (mUC). However, about 50% of patients are considered to be cisplatin ineligible. Anti-PD1/PD-L1 therapies have, nevertheless, increased the options available to clinicians and are especially valuable for treating these patients. This study therefore tested the activity and safety of avelumab as first-line therapy for mUC. PATIENTS AND METHODS Patients with mUC who were ineligible for cisplatin-based chemotherapy were screened centrally for PD-L1 expression and only those with a tumour proportion score (TPS) ≥5% were enrolled in the trial. The primary endpoint was 1-year overall survival (OS), and the secondary endpoints were median OS, median PFS, the ORR, the duration of the response, safety, and tolerability. All the survival rates were estimated with the Kaplan-Meier product-limit methodology and compared across groups using the log-rank test. RESULTS 198 patients were screened, with 71 (35.9%) whose PD-L1 expression was ≥5% enrolled in the study. The median age was 75 years, bladder cancer was the primary tumour in 73.2% of cases, and 25.3% had liver metastases. The main reasons for the cisplatin ineligibility were a low rate of creatinine clearance (< 60 ml/min), present in 70.4% of patients, and an ECOG performance status of 2, which affected 31%. The median OS was 10.0 months (95% CI, 5.5-14.5) and 43% of patients were alive at one year. A complete response was achieved in 8.5% of cases and 15.5% had a partial response. Adverse any-grade and high-grade events occurred in 49.3% and 8.5% of patients, respectively. A grade 3 infusion reaction was the only high-grade treatment-related adverse event. No treatment-related deaths were reported. CONCLUSIONS This ARIES trial confirmed the activity and safety of avelumab for treating mUC, adding a new therapy option to the armamentarium of checkpoint inhibitors already approved for platinum-ineligible, locally advanced/mUC.

Learning effect and repeatability of stabilometric measurements: "standard" vs. usual foot placement. Arch Ital Biol 2021; 159:95-103.

Abstract
The existence of a learning effect by which subjects progressively reduce body sway over the course of repetitive stabilometric measurements is currently debated. Also, the position and orientation of the feet on the platform can have a substantial influence on the outcome measurements. The aim of the present work was to assess the effect of feet positions on mean total velocity (V) of the center of pressure and the area (AR) covered by its displacements during quiet standing. A group of 35 healthy young subjects was examined during two successive sessions consisting of five recordings with their feet placed either in the recommended (standard, SP) or their usual most comfortable (UP) position. Results show a slight decreasing trend that failed to be statistically significant checked with Friedman's ANOVA (SP AR, χ2(4)=6.10, p=0.19 and V, χ2(4)=8.66, p=0.07 and UP AR, χ2(4)=2.32, p=0.68 and V, χ2(4)=1.19, p=0.88). Nonetheless, values of AR and V showed a notable decrement especially evident in the SP exam reaching, respectively, 24% and 11% from baseline, whereas variability measured by the coefficient of variation was the same in the two exams. Given the results, a learning effect should not be ruled out with confidence. Also, usual foot placement would be preferable to avoid this effect. Further research is needed to take into consideration the great variability of stabilometric measurements and the fact that different subjects could adapt more readily to the test conditions than others.

Background
high power short duration (HPSD) ablation is at least as safe while reducing procedure time than radiofrequency (RF) ablation with lower power in pts undergoing pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation (AF). Purpose: to compare safety and efficacy of 2 different: 1) RF energy set up (FlexAbility: 70W, 41°, 6-10s, 11ml/h vs. TactiCath: 50W, 41°, LSI 5-6, 17ml/h, both Abbott), and 2) ablation strategies (posterior wall isolation (PWI) in addition to PVI vs. PVI) in pts undergoing their first ablation for paroxysmal AF. Methods: since June 2020 pts are prospectively assigned to alternatively undergo their RF catheter ablation with the FlexAbility (v-HPSD) or the TactiCath (LSI-HPSD) catheters (aim 200 pts). In addition, pts were alternatively assigned to PVI + PWI vs. PVI. All procedures were done using a 3D-mapping system (Ensite Precision), the ablation catheter was stabilized with a long sheath (Agilis) and a continuous series of lesions (4mm) were plotted around the PV, at the roof and between the 2 inferior PVs. On the PW, RF lesions were limited to 6s and 5 LSI for the v-HPSD and LSI-HPSD groups. Endoscopy was performed shortly after ablation in all pts and thermal esophageal lesion (TEL) characterized with the Kansas classification. Results: since June 2020 56 pts [61 ± 13 years old, 17 (30%) female, CHA2DS2-Vasc 2.3 ± 1.5, 55 ± 77 left ventricular ejection fraction] underwent v-HPSD (#28) and LSI-HPSD (#28) ablation. In 2/14 (14%) and in 3/15 (20%) pts (v-HPSD and LSI-HPSD groups, respectively) initially assigned to undergo simple PVI, PWI was added due to PW dependent flutter or evidence of pro-arrhythmic slow conduction on the PW. A shorter RF time to achieve PVI (17 ± 3 vs. 25 ± 6 min; P<.0001) was found for the v-HPSD group, although acute reconnection were numerically higher (9 vs. 4) and procedural time did not differ (32 ± 8 vs. 35 ± 9 min). Whenever attempted, PWI (#16 for each v-HPSD and LSI-HPSD group) was always successful. When v-HPSD and LSI-HPSD group were compared, no differences were found in RF and procedure time both at the roof (2.3 ± 0.9 vs. 2.7 ± 1.1 min and 3 ± 1.4 vs. 3.4 ± 1 min, respectively) and between the 2 inferior PVs (2.6 ± 0.6 vs. 2.9 ± 0.7 min and 4.3 ± 1.9 vs. 3.8 ± 1.2 min, respectively). Total RF (19.7 ± 4.5 vs. 28.5 ± 6.6 min, P<.0001) was shorted in the v-HPSD, but X-Ray (1.4 ± 0.7 vs. 1.2 ± 0.8 min) and total procedural time (102 ± 17 vs. 110 ± 20 min) did not differ. Rate of TELs was not different and found in 18% (#5: 4 I, 1 IIA) and 14% (all IIA) pts assigned to v-HPSD and LSI-HPSD respectively. A numerically higher number of TELs (6 vs. 3) was seen when PWI was pursued, although this did not prolong total RF and procedure time. Conclusion: a shorter RF time is associated with v-HPSD vs. LSI-HPSD strategy, although procedural time did not differ. TELs are a relative rare finding, and only numerically higher when isolation of the PW is pursued in addition to PV isolation.

Abstract
Abstract
Background
permanent trans-mural lesions not affecting surrounding anatomical structures is the goal of safe and effective wide antral pulmonary vein (PV) isolation in patients with paroxysmal and persistent atrial fibrillation (AF) undergoing catheter ablation (CA). Time, energy and contact force are parameters related to lesion goodness and incorporated in a complex formula (i.e. the lesion index, LSI™, Abbott). This parameter is emerging as the gold standard for PV isolation. Recently, the shallower but wider lesions created by high power short duration (HPSD) ablation has came to attention.
Purpose
to compare acute reconnection rate, procedural parameters, and complication rates in patients with paroxysmal or persistent AF undergoing CA.
Methods
one-hundred patients with paroxysmal and 100 with persistent AF will be alternatively assigned to undergo PV isolation with the FlexAbility™ (HPSD group, 70W, 41°, 8 seconds) or the TactiCath™ (LSI-group: 35W, 41°, LSI: 5-5.5 posterior wall, up to ≥6 anywhere else) catheter. A 3-D mapping system (Ensite Precision™) and a steerable sheath (Agilis™, both Abbott) were always used. Adenosine (30mg) is given after PV isolation and ≥ 20 minutes waiting time. Posterior wall isolation was added in all, and patients with persistent AF were additionally treated with mitral and cavotricuspid isthmus ablation. Results: between June and October 2019, 71 patients (68 ± 10 years old, 32 (45%) female, 44 (60%) paroxysmal AF, AF duration 58 ± 81 months) were alternatively assigned to HPSD (36, 51%) or LSI-guided (35, 49%) ablation. No difference in clinical characteristics was found between groups. After 44 ± 18 and 30 ± 14min of procedural and RF time, all PVs were isolated, and all 17 (24%) reconnections treated with an additional 4 ± 3 and 3 ± 2min, respectively. In 8 ± 3 and 7 ± 3 min of procedural and RF time, the PW was successfully isolated in all. PV isolation (34 ± 12min vs. 56 ± 16min; P<.0001), RF (18 ± 5min vs. 41 ± 9min; P<.0001), and total procedural (138 ± 34min vs. 162 ± 34min; P=.0026) time were shorter in the HPSD group. X-Ray time and effective dose did not differ. A similar rate of acute reconnections (9, 25% vs. 8 23%) was found when HPSD and LSI were compared. A higher, although statistically not significant, number of steam pops was observed in the HPSD (14, 39%) vs. LSI (8, 23%) group, possibly related to the higher incidence of moderate pericardial effusion (>0.5mm, <20mm) found the day following the ablation (10, 28% vs. 2, 6%; P=.0238). No further complications related to CA were detected.
Conclusions
in patients with paroxysmal and persistent AF undergoing their first CA, HPSD ablation is faster than an LSI-guided approach. Acute efficacy (reconnection rate) is similar. Although a higher rate of haemodynamically non-relevant pericardial effusions were seen in the HPSD group, these were all treated medically and the general safety profile of this approach is excellent and comparable to LSI ablation.

Abstract
Abstract
Background
wide antral pulmonary vein (PV) catheter ablation (CA) in patients with atrial fibrillation (AF) is safe and effective when permanent trans-mural lesions are achieved without causing harm to surrounding anatomical structures. Atrio-esophageal fistula, due to its high mortality, is the most dreadful complication related to CA for AF, therefore alternative radiofrequency (RF) approaches to reduce or eliminate this complication are currently studied. The shallower but wider lesions of high power short duration (HPSD) ablation might represent a safe alternative.
Purpose
to compare the rate of thermal esophageal lesions in patients with paroxysmal and persistent AF undergoing CA assigned to the 2 different RF modality.
Methods
one-hundred patients with paroxysmal and 100 with persistent AF will be alternatively assigned to undergo CA with the FlexAbility™ (HPSD group: 70W, 41°, 8 seconds) or the TactiCath™ (LSI-group: 35W, 41°, LSI: 5-5.5 posterior wall, up to 6 anywhere else) catheter. A 3-D mapping system, a steerable sheath and adenosine-test (30mg) were used in all patients. Posterior wall (PW) isolation in addition to PV isolation was performed in all, and patients with persistent AF were additionally treated with mitral and cavotricuspid isthmus ablation. Insertion of an esophageal probe was always attempted, and all patients underwent upper endoscopy 24 to 48 hours after CA.
Results
between June and October 2019, 71 patients (68 ± 10 years old, 32 (45%) female, 44 (60%) paroxysmal AF, AF duration 58 ± 81 months) were alternatively assigned to HPSD (36, 51%) or LSI-guided (35, 49%) ablation. No differences in clinical characteristics were found between groups. After 45 ± 18min and 30 ± 14 min of procedural and RF time, all PVs were isolated, and all spontaneous and adenosine-induced reconnections treated. Successful PW isolation was achieved with an additional 8 ± 3 and 7 ± 3 min of procedural and RF time. When HPSD and LSI-guided groups are compared, a similar rate of clinically non-relevant and self-healing thermal lesions at endoscopy was found (10, 27.8% vs. 10, 28.6%). Independent of the treatment group, a higher peak temperature identified patients with esophageal lesions (43.2° vs. 42°; P=.0065). A peak temperature value of 43.1° best identify patients most likely to develop thermal lesions (AUC 0.71, SE 84%, SP 39%). Interestingly, none of the 11 patients in whom esophageal probe insertion was not possible or attempted developed thermal lesions in comparison to 20 (33%) patients who underwent esophageal temperature monitoring (P=.0046). Conclusions: no difference in thermal induced esophageal lesions were found when the two different RF approach (HPSD vs. LSI guided) were compared. Interestingly, lack of temperature monitoring with an esophageal probe is associated with no thermal lesions at endoscopy.

Abstract
Increasing occlusal vertical dimension (OVD) by means of oral splints is a practice widely used in the treatment of temporomandibular disorders (TMD), specifically myofascial pain, although the results are still uncertain. Oral splints with a vertical height that significantly exceeds the clinical rest position are considered by some researchers to be a better therapeutic solution in alleviating TMD symptoms than are “low” splints.
In our observational study, 21 patients suffering from myofascial pain were examined for the effects of wearing a “high” oral splint while sleeping for 3 months. To ensure proper splint making, a mandibular stretching procedure was used to induce a relaxation of the patients’ masticatory muscles and allow the correct alignment of the jaws. Results showed a marked increase of the interocclusal distance or “free space” (hence of OVD; from 0.64±0.53 mm to 1.42±0.76 mm, p<0.0001) measured by a kinesiograph, followed by a substantial reduction of the intensity of pain in oral and extraoral regions after using the splint. These results support the view that increasing OVD beyond the clinical rest position is not detrimental to patients’ health. More importantly, high oral splints has been shown to be a promising therapeutic aid for the treatment of TMD and correlated pain syndromes. This clinical trial was registered on clinicaltrials.gov (Identifier: NCT02908568).

Abstract
In recent years people suffering of backache has significantly increased. This led us to focus our attention on the adequacy of school furniture for the correct development of the adult posture. The standing posture of 67 students of middle school has been analyzed at the beginning and at the end of two consecutive scholastic years using a stabilometric platform. Starting from the second year, about half of the students were provided with the furniture designed following European standard (UNI EN 1729:2006), while the other half maintained the traditional one. The main purpose of this research has been to verify by means of posturometric analysis the effects on postural parameters of the use of traditional furniture in comparison to the furniture following the UNI EN 1729:2006. We observed that prolonged sitting at school changes some posturometric variables of schoolchildren. Since no differences has been found between the two groups, the validity of the European standards is questioned. The present study allowed us to single out four anthropometric parameters that should be considered in order to devise a new model of adjustable furniture. By adjusting every year the furniture of each student, it would be possible to avoid (at least at school) the adoption of wrong postural positions that could be responsible for backache and other common musculoskeletal disorders.

Abstract
By making use of a recently proposed framework for the inference of thermodynamic irreversibility in bosonic quantum systems, we experimentally measure and characterize the entropy production rates in the nonequilibrium steady state of two different physical systems-a micromechanical resonator and a Bose-Einstein condensate-each coupled to a high finesse cavity and hence also subject to optical loss. Key features of our setups, such as the cooling of the mechanical resonator and signatures of a structural quantum phase transition in the condensate, are reflected in the entropy production rates. Our work demonstrates the possibility to explore irreversibility in driven mesoscopic quantum systems and paves the way to a systematic experimental assessment of entropy production beyond the microscopic limit.

Abstract
Oil Red O is a useful tool to assess donor liver steatosis on frozen sections during transplantation. Steatosis is a frequent finding in liver evaluation during transplantation, accounting for 9% to 26% of biopsied donor liver. The degree of macrovesicular steatosis is classified as mild, moderate, and severe; the latter is considered an absolute contraindication to liver transplantation because it is associated with poor allograft outcome. Because of the scarcity of organs, there is a debate whether livers with less severe macrovesicular steatosis are still suitable for transplant. Consequently, tools or methods that allow a more accurate intraoperative assessment of steatosis on frozen sections are mandatory. The aim of this study is to improve intraoperative evaluation of steatosis during transplantation using Oil Red O stain on liver biopsies. METHODS Twenty consecutive liver biopsies of donors were collected during transplantation procedures from September 2017 to February 2018 at the Institute of Pathology of the University and Hospital Trust of Verona, Italy. Each liver biopsy was cut at a different thickness (3, 5, and 8 μm) and stained with both Oil Red O and conventional hematoxylin and eosin for intraoperative consultation. The degree (percentage of hepatocytes involved) of fatty changes was recorded. The results obtained during the intraoperative consultation were finally compared with the formalin-fixed and paraffin-embedded permanent section. RESULTS Assessment of steatosis on hematoxylin and eosin frozen sections was reported as mild in 17 cases (85%), moderate in 2 cases (10%) and severe in 1 case (5%). Oil Red O frozen sections reported the following results: mild steatosis in 16 cases (80%), moderate in 2 cases (10%), and severe in 2 cases (10%). The percentage of liver steatosis obtained with Oil Red O was consistent in all cases with that of the permanent sections. The staining procedure for Oil Red O required approximately 18 minutes. CONCLUSIONS Oil Red O special stain is a fast and inexpensive tool to improve the assessment of steatosis on frozen biopsies during liver transplantation.

Abstract
BACKGROUND Assessment of potential liver allograft donors with frozen sections has clinical relevant consequences for the transplant recipient. Several clinical risk factors have been identified that increase the risk of transplantation failure and it is critical for the pathologist to become familiar with the histologic criteria for donor liver suitability. In this setting an accurate and reliable assessment of fibrosis is crucial. We sought to report the value of the rapid chromotrope aniline blue stain (CAB) in a transplantation clinical work-flow for scoring liver fibrosis. MATERIALS AND METHODS Twenty consecutive intraoperative donor liver biopsy specimens were evaluated by a pathologist at the Transplant Pathology Board Room, AOUI Verona, during 24-hour on-call service. The stage of fibrosis was evaluated according to Ishak score ranging from 0 to 6 (absent to cirrhosis) using hematoxylin and eosin stain (H&E) plus rapid CAB special stain. After a 3-week washout period, only the slides stained with H&E were re-assessed for fibrosis stage by the same pathologist blinded to donor patient data. RESULTS Combination H&E-CAB staging fibrosis score was higher in 20%, lower in 10%, and the same in 70% of biopsy specimens as determined using only H&E stain alone. Rapid CAB stain takes 20 minutes longer than H&E stain alone. CONCLUSIONS CAB staining may be performed on frozen tissue from liver biopsy during a transplantation process without a significant delay in diagnosis. Combination H&E-CAB staining improves sensibility of interpretation of fibrosis.

Abstract
3D polymeric scaffolds are increasingly used for in vitro experiments aiming to mimic the environment found in vivo, to support for cellular growth and to induce differentiation through the application of external mechanical cues. In research, experimental results must be shown to be reproducible to be claimed as valid and the first clause to ensure consistency is to provide identical initial experimental conditions between trials. As a matter of fact, 3D structures fabricated in batch are supposed to present a highly reproducible geometry and consequently, to give the same bulk response to mechanical forces. This study aims to measure the overall mechanical response to compression of commercially available 3D Insert PCL scaffolds (3D PCL) fabricated in series by fuse deposition and evaluate how small changes in the architecture of scaffolds affect the mechanical response. The apparent elastic modulus (Ea) was evaluated by performing quasi-static mechanical tests at various temperatures showing a decrease in material stiffness from 5MPa at 25°C to 2.2MPa at 37°C. Then, a variability analysis revealed variations in Ea related to the repositioning of the sample into the testing machine, but also consistent differences comparing different scaffolds. To clarify the source of the differences measured in the mechanical response, the same scaffolds previously undergoing compression, were scanned by micro computed tomography (μCT) to identify any architectural difference. Eventually, to clarify the contribution given by differences in the architecture to the standard deviation of Ea, their mechanical response was qualitatively compared to a compact reference material such as polydimethylsiloxane (PDMS). This study links the geometry, architecture and mechanical response to compression of 3D PCL scaffolds and shows the importance of controlling such parameters in the manufacturing process to obtain scaffolds that can be used in vitro or in vivo under reproducible conditions.

Abstract
Background The correlation between ALK gene copy number gain (ALK-CNG) and prognosis in the context of advanced non-small-cell lung cancer (NSCLC) remains a controversial issue. This study aimed to evaluate the association among ALK-CNG according to Fluorescent In Situ Hybridization (FISH), clinical characteristics and survival in resectable and advanced NSCLC. Methods Clinical and pathological data of patients with resectable and advanced NSCLC were retrospectively collected. Tumor tissues were analyzed for ALK-CNG by FISH, and patients were divided in 3 groups/patterns on the basis of ALK signals: disomic [Pattern A], 3–7 signals [Pattern B], >7 signals [Pattern C]. The association between clinical and pathological features and ALK-CNG patterns was evaluated. Disease/progression-free and overall survival (DFS/PFS and OS) were estimated using the Kaplan-Meyer method. Results A number of 128 (76.6 %) out of the 167 eligible patients were evaluable for ALK-CNG, displaying pattern A, B and C in 71 (42.5 %), 42 (25.1 %) and 15 (9 %) patients, respectively. Gains in ALK-CNG appear to be more frequent in smokers/former smokers than in non-smokers (74.2 % versus 20.4 %, respectively, p = 0.03). Pattern A and C seem more frequently associated with higher T-stage (T3-4), while pattern B appears more represented in lower T-stage (T 1-2) (p = 0.06). No significant differences in survival rate were observed among the above groups. Conclusions A high ALK-CNG pattern might be associated with smoking status and theoretically it might mirror genomic instability. The implications for prognosis should be prospectively investigated and validated in larger patients’ series. Trial registration We confirm that all the study was performed in accordance with relevant guidelines and regulations and that all the protocol (part of a larger project MFAG 2013 N.14282) was approved by the local Ethics Committee of the Azienda Ospedaliera Universitaria Integrata of Verona on November 11st, 2014.
