Abstract
The human vasculature is essential in organs and tissues for the transport of nutrients, metabolic waste products, and the maintenance of homeostasis. The integration of vessels in in vitro organs-on-chip may, therefore, improve the similarity to the native organ microenvironment, ensuring proper physiological functions and reducing the gap between experimental research and clinical outcomes. This gap is particularly evident in drug testing and the use of vascularized models may provide more realistic insights into human responses to drugs in the pre-clinical phases of the drug development pipeline. In this context, different vascularized liver models have been developed to recapitulate the architecture of the hepatic sinusoid, exploiting either porous membranes or bioprinting techniques. In this work, we developed a method to generate perfusable vascular channels with a circular cross section within organs-on-chip without any interposing material between the parenchyma and the surrounding environment. Through this technique, vascularized liver sinusoid-on-chip systems with and without the inclusion of the space of Disse were designed and developed. The recapitulation of the Disse layer, therefore, a gap between hepatocytes and endothelial cells physiologically present in the native liver milieu, seems to enhance hepatic functionality (e.g., albumin production) compared to when hepatocytes are in close contact with endothelial cells. These findings pave the way to numerous further uses of microfluidic technologies coupled with vascularized tissue models (e.g., immune system perfusion) as well as the integration within multiorgan-on-chip settings.

Abstract
Infants with KMT2A-rearranged B-cell acute lymphoblastic leukemia (ALL) have a dismal prognosis. Survival outcomes have remained static in recent decades despite treatment intensification and novel therapies are urgently required. KMT2A-rearranged infant ALL cells are characterized by an abundance of promoter hypermethylation and exhibit high BCL-2 expression, highlighting potential for therapeutic targeting. Here, we show that hypomethylating agents exhibit in vitro additivity when combined with most conventional chemotherapeutic agents. However, in a subset of samples an antagonistic effect was seen between several agents. This was most evident when hypomethylating agents were combined with methotrexate, with upregulation of ATP-binding cassette transporters identified as a potential mechanism. Single agent treatment with azacitidine and decitabine significantly prolonged in vivo survival in KMT2A-rearranged infant ALL xenografts. Treatment of KMT2A-rearranged infant ALL cell lines with azacitidine and decitabine led to differential genome-wide DNA methylation, changes in gene expression and thermal proteome profiling revealed the target protein-binding landscape of these agents. The selective BCL-2 inhibitor, venetoclax, exhibited in vitro additivity in combination with hypomethylating or conventional chemotherapeutic agents. The addition of venetoclax to azacitidine resulted in a significant in vivo survival advantage indicating the therapeutic potential of this combination to improve outcome for infants with KMT2A-rearranged ALL.

Abstract
Antarctica has been affected directly and indirectly by human pressure for more than two centuries and recently plastic pollution has been recognized as a further potential threat for its unique biodiversity. Global long-range transport as well as local input from anthropogenic activities are potential sources of plastic pollution in both terrestrial and marine Antarctic territories. The present study evaluated the presence of microplastics in specimens of the Antarctic whelk Neobuccinum eatoni, a key species in benthic communities of the Ross Sea, one of the largest marine protected areas worldwide. To this aim, a thermo-oxidative extraction method was applied for microplastic isolation and quantification, and polymer identification was performed by manual μ-FTIR spectroscopy. Textile (semi-)synthetic or composite microfibers (length range: 0.8-5.7 mm) were found in 27.3% of whelk specimens, suggesting a low risk of bioaccumulation along Antarctic benthic food webs in the Ross Sea. Their polymer composition (of polyethylene terephthalate and cellulose-polyamide composites) matched those of outdoor technical clothing in use by the personnel of the Italian "Mario Zucchelli" station near Terra Nova Bay in the Ross Sea. Such findings indicate that sewage from base stations may act as potential local sources of textile microplastic fibers in this remote environment. More in-depth monitoring studies aiming at defining the extent of microplastic contamination related to such sources in Antarctica are encouraged.

Background
Female gender, degree of QT prolongation and genetic susceptibility are known risk factors for developing torsade de pointe (TdP) during high-degree atrioventricular block (HD-AVB).
Objective
To analyze the incidence and clinical characteristics of patients presenting with TdP and AVB (TdP [+]) in comparison with non-TdP patients with AVB (TdP [-]).
Methods
All the ECG from patients prospectively admitted for advanced AVB (2 to 1 and complete) at our university hospital were analyzed. Automated corrected QT (QTc), and manual measurements of QT and JT intervals, and Tpeak-Tend were performed at the time of most severe bradycardia.
Results
From Sept 2020 to Nov 2021, 100 patients were admitted for HD-AVB. Among them, 17 patients with TdP were identified (8 men; 81 ± 10 years). No differences could be identified concerning automated QTc, manual QTc (Bazett correction), baseline QRS width and mean left ventricular ejection fraction between the two groups. Potassium serum level on admission and mean number of QT-prolongating drugs per patient were not significantly different between the two groups, respectively: 4.34 ± 0.5 in TdP [+] versus 4.52 ± 0.6 mmol/L (p = 0.33); and 0.6 ± 0.7 in group A versus 0.5 ± 0.7 (p = 0.15). In contrast, manual QTcFR (Fridericia correction), corrected JT, Tpeak-to-end and Tpe/QT ratio were significantly increased in the TdP [+] group: respectively 486 ± 70 versus 456 ± 53 ms (p = 0.04); 433 ± 98 versus 381 ± 80 (p = 0.02); 153 ± 57 versus 110 ± 40 (p < 0.001); 0.27 ± 0.08 versus 0.22 ± 0.06 (p < 0.001).
Conclusion
The incidence of TdP complicating acquired AVB was 17 % in a medium-volume center. Longer QTc (Fridericia), corrected JT and Tpeak-to-end were electrocardiographic predictors of TdP, while no clinical characteristics may predict the occurrence of this complication.

Abstract

Type of funding sources: None.
Background
Axillary vein (AV) puncture, an emerging route for cardiac implantable electronic devices (CIED), can be performed under ultrasounds (US) or fluoroscopic (Fluo) guidance.
Objective
To compare US to fluroroscopy-guided AV puncture in a multicenter randomized controlled trial.
Methods
Consecutive patients admitted for CIED (first implant or upgrade, including resynchronization therapy) intervention were prospectively randomized between US or Fluo guidance for AV puncture in the three participating centers. Access performances, radiation exposure and complications were compared in both groups.
Results
102 patients were included (n = 51 patients per group). The two groups had similar characteristics concerning age (79.4 ± 10 years), and LVEF (47 ± 17%). 92 leads were implanted in both groups. AV catheterization was successful in 50/51 (98 %) in the US group versus 49/51 in the Fluo group (96 %, p = 0.56). AV access time and procedure time were not different between the two groups, respectively (156 ± 274 in the US group versus 137 ± 151 sec, p = 0.66; 54 ± 24 versus 61 ± 26 min; p = 0.13). Total fluoroscopy time (FT) and dose-area product were respectively lower in the US group, but without reaching significance: 197 ± 231 versus 247 ± 293 sec, p = 0.32; 0.39 ± 0.95 versus 0.75 ± 1.58 mGy.m², p = 0.14. FT for AV access was significantly higher in the Fluo group (51 ± 55 sec versus 0, p < 0.0001). There were two complications in each group during the 9 ± 6 months follow-up.
Conclusion
Our study demonstrates that both US and fluoroscopy-guided AV catheterization for CIED are highly effective and safe techniques. Despite similar AV access time, compared to fluo guidance, US reduce time radiation exposure by 20 %.

Abstract
The Pfizer/BioNtech Comirnaty vaccine (BNT162b2 mRNA COVID-19) against SARS-CoV-2 is currently in use in Italy. Antibodies to evaluate SARS-CoV-2 infection prior to administration are not routinely tested; therefore, two doses may be administered to asymptomatic previously exposed subjects. The aim of this study is to assess if any difference in antibody concentration between subjects exposed and not exposed to SARS-CoV-2 prior to BNT162b2 was present after the first dose and after the second dose of vaccine. Data were retrospectively collected from the clinical documentation of 337 healthcare workers who underwent SARS-CoV-2 testing before and after BNT162b2. Total anti RBD (receptor-binding domain) antibodies against SARS-CoV-2′s spike protein were measured before and 21 days after the first dose, and 12 days after the second dose of BNT162b2. Twenty-one days after the first dose, there was a statistically significant difference in antibody concentration between the two groups, which was also maintained twelve days after the second dose. In conclusion, antibody response after receiving BNT162b2 is greater in subjects who have been previously exposed to SARS-CoV-2 than in subjects who have not been previously exposed to the virus, both after 21 days after the first dose and after 12 days from the second dose. Antibody levels, 21 days after the first dose, reached a titer considered positive by the test manufacturer in the majority of subjects who have been previously infected with SARS-CoV-2. Evaluating previous infection prior to vaccination in order to give the least effective number of doses should be considered.

Abstract
OBJECTIVE To appraise the highest evidence on hip morphology as a risk factor for developing hip osteoarthritis (OA). DESIGN We searched for studies evaluating the association between radiological hip morphology parameters and the prevalence, incidence or progression of hip OA (based on different radiographic and clinical criteria) in the MEDLINE, EMBASE, Web of Science, Scopus, Cochrane Library and PEDro databases from inception until June 2020. Prospective and cross-sectional studies were separately evaluated. Data are presented as odds ratios (OR) with 95% confidence intervals (CI). RESULTS We included 9 prospective and 21 cross-sectional studies in the meta-analysis, and evaluated 42,831 hips from 25,898 individuals (mean age: 59 years). Prospective studies showed that, compared with control hips, hips with cam morphology (alpha angle >60°; OR = 2.52, 95% CI: 1.83 to 3.46, P < 0.001) or hip dysplasia (lateral center-edge angle (LCEA) <25°; OR = 2.38, 95% CI: 1.84 to 3.07, P < 0.001), but not hips with pincer morphology (LCEA >39°; OR = 1.08, 95% CI: 0.57 to 2.07, P = 0.810), were more likely to develop hip OA than hips without these morphologies. Cross-sectional studies showed a greater prevalence of pincer morphology (LCEA >39°, OR = 3.71, 95% CI: 2.98 to 4.61, P < 0.001) and acetabular retroversion (crossover sign; OR = 2.65, 95% CI: 1.17 to 6.03, P = 0.020) in hips with OA than in control hips. CONCLUSION Cam morphology and hip dysplasia were consistently associated with the development of hip OA. Pincer morphology was associated with hip OA in cross-sectional but not in prospective studies. The heterogeneous quantification of pincer morphology on radiographs limits a clear conclusion on its association with hip OA.

Abstract
BACKGROUND Infants with KMT2A-rearranged B-cell precursor acute lymphoblastic leukemia (ALL) have poor outcomes. There is an urgent need to identify novel agents to improve survival. Proteasome inhibition has emerged as a promising therapeutic strategy for several hematological malignancies. The aim of this study was to determine the preclinical efficacy of the selective proteasome inhibitor carfilzomib, for infants with KMT2A-rearranged ALL. METHODS Eight infant ALL cell lines were extensively characterized for immunophenotypic and cytogenetic features. In vitro cytotoxicity to carfilzomib was assessed using a modified Alamar Blue assay with cells in logarithmic growth. The Bliss Independence model was applied to determine synergy between carfilzomib and the nine conventional chemotherapeutic agents used to treat infants with ALL. Established xenograft models were used to identify the maximal tolerated dose of carfilzomib and determine in vivo efficacy. RESULTS Carfilzomib demonstrated low IC50 concentrations within the nanomolar range (6.0-15.8 nm) across the panel of cell lines. Combination drug testing indicated in vitro synergy between carfilzomib and several conventional chemotherapeutic agents including vincristine, daunorubicin, dexamethasone, L-asparaginase, and 4-hydroperoxycyclophosphamide. In vivo assessment did not lead to a survival advantage for either carfilzomib monotherapy, when used to treat both low or high disease burden, or for carfilzomib in combination with multi-agent induction chemotherapy comprising of vincristine, dexamethasone, and L-asparaginase. CONCLUSIONS Our study highlights that in vitro efficacy does not necessarily translate to benefit in vivo and emphasizes the importance of in vivo validation prior to suggesting an agent for clinical use. Whilst proteasome inhibitors have an important role to play in several hematological malignancies, our findings guard against prioritization of carfilzomib for treatment of KMT2A-rearranged infant ALL in the clinical setting.

Abstract
BACKGROUND Complete atrioventricular block (AVB3) may be an urgent potentially lifethreatening situation. Our objective was to describe the routine management of AVB 3, with emphasis on the organizational aspects. METHODS From September 2019 to November 2019, a prospective national survey including 28 questions was electronically sent to 100 physicians (Google Form). RESULTS The answers were collected from 93 physicians (response rate 93%). Permanent pacemaker implantation during weekends and nights (after 8PM) is possible for 49% of the operators (<5 times a year), for 15% (>5 times a year), impossible for 36% of the operators. For AVB3 nonresponsive to isoproterenol occurring during the night, a temporary pacing lead (TPL) is implanted by: the on-site medical staff on-duty (27%), the on-call interventional cardiologist (21%), the on-call electrophysiologist (19%), a permanent pacemaker is implanted by the electrophysiologist (12%), the strategy is not standardized (15%). An externalized active fixation lead (AFL) for AVB3 has already been implanted by 50% of the operators. 80 (86%) have already observed a dislocation of the TPL, a cardiac perforation already occurred in 57 (61%), a groin hematoma in 35 (38%), and this technique was proscribed for 4% of the operators. CONCLUSION Our survey shows important disparities in terms of management of AVB3 among the different centers. An externalized AFL with a reusable generator was used by half of the centers.

Abstract
Abstract
Background
Transcatheter aortic valve implantation (TA) is the preferred treatment modality for patients with severe aortic valve disease at high surgical risk and is expanding into lower risk populations. Therefore age range of treated patients is increasing.
Purpose
The aim of this study is to analyze age-related clinical and hemodynamic outcome of patients following TAVI in a nationwide, prospective, multicentre cohort (Swiss TAVI registry).
Methods
We retrospectively analyzed prospectively collected data from all patients included in the Swiss TAVI registry between February 2011 and December 2018. In an adjusted analysis, in-hospital, 30-days and 1-year outcome between four age groups were compared.
Results
Overall, 7097 patients underwent TAVI (<70 years: n=324, 70–79 years: n=1913, 80–89 years: n=4353, 90–100 years n=507). Median STS risk score for mortality was 5.23±4.13% and differed significantly between age groups (3.46±4.10%, 3.97±3.73%, 5.57±3.97%, 8.22±4.74%; p=0.001). Valve predilatation was more often performed in older patients (54.3% vs. 54.3% vs. 60.7% vs. 69.6%; p≤0.001). Difference in hospital stay was statistically sigificant between age groups, numerically however not relevant (10.01±7.56 days vs. 9.25±6.38 days vs. 9.55±5.70 days vs 10.03±5.77 days; p=0.02). Post-procedural acute kidney injury stage 3 was highest in the youngest age group (3.4% vs. 1.6% vs. 1.1% vs. 1.0%; RR [95% CI] 0.65 (0.48–0.87); p=0,004) and rate of new pacemakers for conduction abnormalities increased significantly with age (10.2% vs. 13.7% vs. 17.1% vs. 18.7%; RR [95% CI] 1.22 (1.12–1.32); p<0.001). There was no significant difference in life threatening/major bleeding (p=0.288/0.197) or major vascular complications (p=0.083).
All-cause mortality and cardiovascular mortality in hospital, at 30 days and at 1 year were highest in nonagenarians and higher in the patients <70 years compared to patients of 70–79 years: in hospital all-cause mortality 2.2% vs. 1.6% vs. 2.9% vs. 5.5% (RR [95% CI] 1.64 (1.28–2.10), p<0.001); 30 day all-cause mortality 3.1% vs. 2.0% vs. 3.7% vs. 6.7%; (HR [95% CI] 1.59 (1.30–1.96); p<0.0001); 1-year all-cause mortality 10.9% vs. 10.4% vs. 12% vs. 19.5% (HR [95% CI] 1.27 (1.14–1.41); p<0.001); in hospital cardiovascular mortality 1.5% vs. 1.5% vs. 2.6% vs. 5.1% (RR [95% CI] 1.70 (1.31–2.20), p<0.001); 30 day cardiovascular mortality 2.2% vs. 1.9% vs. 3.3% vs. 6.3%; (HR [95% CI] 1.68 (1.35–2.09); p<0.001); 1-year cardiovascular mortality 7.2% vs. 6.9% vs. 8.3% vs. 15.3% (HR [95% CI] 1.36 (1.19–1.55); p<0.001). This held true, when hazard ratio was corrected for STS PROM score, femoral access vs other access and year of procedure.
Conclusion
In-hospital, 30-day and 1-year clinical outcome of nonagenarians undergoing TAVI are less favorable compared to lower age groups. Interestingly, clinical outcome of the patients group 70–79 years was the most favorable.

Abstract
Abstract
Background
The axillary route use for cardiac devices implantation has recently expanded either with fluoroscopy or ultrasounds guidance. Few studies included defibrillators (ICD), cardiac resynchronization therapy (CRT) and upgrade procedures for ultrasound-guided axillary vein puncture (UGVP).
Puropose
To assess the feasibility/safety of UGVP for complex cardiac devices implantation including CRT/ICD.
Methods
Consecutive patients eligible for a pacemaker or ICD implantation were included.
All procedures were performed by three operators (one experienced and two fellows). Guidewires insertion time (from lidocaïne administration), and complications were systematically studied. A group of patients implanted with alternative techniques was used for comparison (cephalic, subclavian).
Results
In 176 consecutive patients in whom UGVP was used, a total of 68 complex procedures were analyzed (74 ± 8 y, male 61 %) with 138 leads implanted including 42 ICD, 48 CRT and 16 upgrade procedures. A majority (83 %) was under anti-thrombotic therapy. UGVP was successful in 96.8 %. Mean insertion time for 1.78 guidewires per patient was 4.4 ± 4.4 min. Guidewires insertion time reached its plateau after 10 patients. One pocket hematoma (1.4 %) was drained during a mean follow-up of 12 ± 5 months. The control group included 28 patients (12 subclavian, 16 cephalic; 15 ICD, 18 CRT, 4 upgrade procedures), with a mean insertion time of 10 ± 8 min, for 1.95 guidewires per patient (p < 0.0005).
Conclusion
UGVP is feasible and safe even for complex device implantations including CRT/ICD and upgrade procedures.

Abstract
This paper provides a first insight of the potential of the β- Radio Guided Surgery (β--RGS) in a complex surgical environment like the abdomen, where multiple sources of background concur to the signal at the tumor site. This case is well reproduced by ex-vivo samples of 90Y-marked Gastro-Entero-Pancreatic Neuroendocrine Tumors (GEP NET) in the bowel. These specimens indeed include at least three wide independent sources of background associated to three anatomical districts (mesentery, intestine, mucose). The study is based on the analysis of 37 lesions found on 5 samples belonging to 5 different patients. We show that the use of electrons, a short range particle, instead of γ particles, allows to limit counts read on a lesion to the sum of the tumor signal plus the background generated by the sole hosting district.The background on adjacent districts in the same specimen/patient is found to differ up to a factor 4, showing how the specificity and sensitivity of the β--RGS technique can be fully exploited only upon a correct measurement of the contributing background. This locality has been used to set a site-specific cut-off algorithm to discriminate tumor and healthy tissue with a specificity of 100% and a sensitivity, on this test data sample, close to 100%. Factors influencing the sensitivity are also discussed. One of the specimens set allowed us evaluate the volume of the lesions, thus concluding that the probe was able to detect lesions as small as 0.04 mL in that particular case.

Abstract
BACKGROUND
Pulmonary arterial hypertension (PAH) is a life-threatening condition. Current ESC guidelines recommend exercise training and rehabilitation in clinically stable PAH patients.
PURPOSE
To assess the beneficial effect of exercise training on exercise capacity, quality of life and cardiac function as assessed by echocardiography and cardio-pulmonary exercise test.
METHODS
We prospectively included 12 clinically stable PAH patients over a 6 months period. Exercise stress echocardiography (ESE), cardio-pulmonary exercise test (CPET), SF-12 quality of life health survey, 6 minute walking test distance (6MWD), BNP and clinical assessment were performed before and after cardio-pulmonary rehabilitation. Patients underwent 8 weeks of exercise training (3 times a week of aerobic training and at home daily prescribed exercises).
RESULTS
All patients underwent ESE and CPET without any complication. 6 patients experienced a reduction in WHO functional class whereas 6 remained stable. Patients significantly improved their physical quality of life (p = 0.006). They also improved their exercise capacity according to maximum workload during CPET (p = 0.008) and CPET duration (p = 0.001) whereas a trend toward an improved 6MWD was observed (+58m, p = 0.10). Anaerobic threshold and peak VO2 (+1.7 ± 2.7 mL/kg/min) improved significantly (p = 0.01 and 0.03). Regarding imaging data, at rest peak strain improved after rehabilitation (p = 0.05) whereas the RV became more dilated. RV contractile reserve, defined by the change in peak systolic longitudinal RV strain between rest and maximum exercise, significantly improved (-3.9 ± 4.7%, p = 0.03)
CONCLUSION
In this preliminary study, cardio-pulmonary rehabilitation led to an improved quality of life and exercise capacity in PAH. The increased in RV contractile reserve post-rehabilitation might explain, in association with the peripheral muscular effects of exercise training, the clinical benefits of rehabilitation in PAH.

Abstract
Abstract
INTRODUCTION
Right ventricular (RV) contractile reserve reflects the ability of the RV to adapt to elevated afterload. RV functional response to exercise is challenging but could represent an important prognostic factor, especially in pulmonary arterial hypertension (PAH) patients. We aimed, using exercise stress echocardiography (ESE), to assess different RV contractile reserve evaluation methods in a cohort of PAH patients and controls.
METHODS
We prospectively included 12 patients with PAH and 12 healthy volunteers. An ESE (using tilt-table ergometer) was performed in all patients to assess RV function at rest and under peak exercise. Changes in these parameters during exercise were calculated to quantify the RV contractile reserve. 3D RV function as well as peak systolic strain, pulmonary pressures, TAPSE, pulmonary TVI and pulmonary output (using the right ventricular outflow tract diameter) were assessed in all patients.
RESULTS
Our patient group was composed by PAH patients, 61.5 ± 14.8 years; mean age of our control group was 29.33 ± 5.5 years. PAH patients achieved an exercise with a mean workload of 69.17 ± 26.4 Watts. There was no complication after the exercise test in all patients. Change in TAPSE was not significantly different between patients and controls (p = 0.17), whereas change in pulmonary TVI, pulmonary output and RV peak systolic strain was highly discriminant (respectively p = 0.03, p = 0.009 and p = 0.0009). Regarding RV contractile reserve parameters, RV end-systolic pressure area ratio (peak/rest) was not statistically different between controls and patients (p = 0.14) whereas change in TAPSE/sPAP, RV peak strain/sPAP, 3D RV EF/sPAP were significantly different (p = 0.005, p= 0.0008, p = 0004).
CONCLUSION
Changes in pulmonary output, RV peak systolic strain as well as changes in TAPSE/sPAP but mainly RV peak strain/sPAP, 3D RV EF/sPAP represent consistent and feasible tools to assess RV contractile reserve.

Abstract
The transverse emittance of the electron beam is a fundamental parameter in linac-based x-ray free-electron lasers (FELs). We present results of emittance measurements carried out at SwissFEL, a compact x-ray FEL facility at the Paul Scherrer Institute in Switzerland, including a description of the novel high-resolution measurement techniques and the optimization procedure. We obtained slice emittance values at the undulator entrance down to 200 nm for an electron beam with a charge of 200 pC and an rms duration of 30-40 fs. Furthermore, we achieved slice emittances as low as 100 nm for 10 pC beams with few fs duration. These values set new standards for electron linear accelerators. The quality, verification, and control of our electron beams allowed us to generate high-power FEL radiation for a wavelength as short as 0.1 nm using an electron beam with an energy of only 6 GeV. The emittance values demonstrated at SwissFEL would allow producing hard x-ray FEL pulses with even lower-energy beams, thus paving the way for even more compact and cost-effective FEL facilities.

Abstract
Clinic-ambulatory blood pressure (BP) difference is influenced by patients- and device-related factors and inadequate clinic-BP measurement. We investigated whether nonadherence to antihypertensive medications may also influence this difference in a post hoc analysis of the DENERHTN trial (Renal Denervation for Hypertension). We pooled the data of 77 out of 106 evaluable patients with apparent resistant hypertension who received a standardized antihypertensive treatment and had both ambulatory BP and drug-screening results available at baseline after 1 month of standardized triple therapy and at 6 months on a median of 5 antihypertensive drugs. After drug assay samplings on study visits, patients took their antihypertensive treatment under supervision immediately after the start of the ambulatory BP recording, and supine clinic BP was measured 24 hours post-dosing; both allowed to calculate the clinic minus daytime ambulatory systolic BP (SBP) difference (clinic-SBP–day-SBP). A total of 29 (37.7%) were found nonadherent to medications at baseline and 38 (49.4%) at 6 months. At baseline, the mean clinic-SBP–day-SBP difference in the nonadherent group was 12.7 mm Hg (95% CI, 7.8–17.7 mm Hg,
P
<0.001). In contrast, clinic SBP was almost identical to day-SBP in the adherent group (clinic-SBP–day-SBP difference, 0.1 mm Hg; 95% CI, −3.3 to 3.5 mm Hg;
P
=0.947). Similar observations were made at 6 months. Using receiver operating characteristics curves, we found that a 6 mm Hg cutoff of clinic-SBP–day-SBP difference had 67% sensitivity and 69% specificity to predict nonadherence to the triple therapy at baseline. In conclusion, a large clinic-SBP–day-SBP difference may help discriminating between adherence and nonadherence to treatment in patients with resistant hypertension.

Abstract
Background: Leukoaraiosis (LA) is a common radiological finding in elderly, frequently associated with several clinical disorders, including unexplained dizziness. The pathogenesis of LA is multifactorial, with a dysfunction of cerebral microcirculation resulting in chronic hypoperfusion and tissue loss, with oxidative stress involved in this cascade. Objective: The aim of this study was to analyse some oxidative stress biomarkers in a cohort of LA patients. Method: Fifty-five consecutive patients (33 males, median age 75 years) with LA were recruited. In a subgroup of 33 patients with LA and unexplained dizziness, we have then performed an open study to evaluate if 60-day supplementation with a polyphenol compound may modify these biomarkers and influence quality of life, analysed with the Dizziness Handicap Inventory (DHI) scale. Results: At baseline, blood oxidative stress parameters values were outside normal ranges and compared to matched healthy controls. After the two months supplementation, we observed a significant decrement of advanced oxidation protein products values and a significant improvement of DHI. Conclusion: Oxidative stress biomarkers may be useful to detect redox imbalance in LA and to provide non-invasive tools to monitor disease status and response to therapy.

Abstract
PURPOSE The lack of inter-method agreement can produce inconsistent results in neuroimaging studies. We evaluated the intra-method repeatability and the inter-method reproducibility of two widely-used automatic segmentation methods for brain MRI: the FreeSurfer (FS) and the Statistical Parametric Mapping (SPM) software packages. METHODS We segmented the gray matter (GM), the white matter (WM) and subcortical structures in test-retest MRI data of healthy volunteers from Kirby-21 and OASIS datasets. We used Pearson's correlation (r), Bland-Altman plot and Dice index to study intra-method repeatability and inter-method reproducibility. In order to test whether different processing methods affect the results of a neuroimaging-based group study, we carried out a statistical comparison between male and female volume measures. RESULTS A high correlation was found between test-retest volume measures for both SPM (r in the 0.98-0.99 range) and FS (r in the 0.95-0.99 range). A non-null bias between test-retest FS volumes was detected for GM and WM in the OASIS dataset. The inter-method reproducibility analysis measured volume correlation values in the 0.72-0.98 range and the overlap between the segmented structures assessed by the Dice index was in the 0.76-0.83 range. SPM systematically provided significantly greater GM volumes and lower WM and subcortical volumes with respect to FS. In the male vs. female brain volume comparisons, inconsistencies arose for the OASIS dataset, where the gender-related differences appear subtler with respect to the Kirby dataset. CONCLUSIONS The inter-method reproducibility should be evaluated before interpreting the results of neuroimaging studies.

Abstract
Short wavelength free-electron lasers (FELs), providing pulses of ultrahigh photon intensity, have revolutionized spectroscopy on ionic targets. Their exceptional photon flux enables multiple photon absorptions within a single femtosecond pulse, which in turn allows for deep insights into the photoionization process itself as well as into evolving ionic states of a target. Here we employ ultraintense pulses from the FEL FERMI to spectroscopically investigate the sequential emission of electrons from gaseous, atomic argon in the neutral as well as the ionic ground state. A pronounced forward-backward symmetry breaking of the angularly resolved emission patterns with respect to the light propagation direction is experimentally observed and theoretically explained for the region of the Cooper minimum, where the asymmetry of electron emission is strongly enhanced. These findings aim to originate a better understanding of the fundamentals of photon momentum transfer in ionic matter.

Abstract
SummarySome haemostatic parameters have been evaluated in a group of rigorously selected patients with maturity-onset diabetes mellitus without thromboembolic complications and in apparently normal subjects of the same age before and after the venous occlusion test (VOT).In basal conditions diabetics had higher levels of AT III as biological activity and higher fibrinolytic and antifibrinolytic activities than controlsAfter VOT, F VIII R:Ag increased significantly in both groups, more markedly in controls than in diabetics, while F VIII: C showed no modification.Also AT III R:Ag increased after the test, but such variation was significant only in diabetics; on the contrary, the biological activity of AT III was always significantly decreased after the test.After VOT there were also in both groups highly significant increases in the fibrinolytic and antifibrinolytic activities.Finally, HbA1c levels directly correlated with AT III as biological activity before VOT, but with no other parameter either before or after the test.These data suggest the existence in patients with diabetes mellitus without thromboembolic complications of an activated protective mechanism against intravascular clotting.

Abstract
The efficacy of presoaked porcine collagen shields was compared with subconjunctivally injected corticosteroids and antibiotics in reducing ocular inflammation after ECCE with IOL implantation, and signs of reduced oxygen delivery to the cornea were assessed. Fifty eyes of fifty patients were recruited. At the end of surgery 25 eyes (group 1) received a 24-h shield presoaked with 0.1% betamethasone disodium phosphate and 0.5% netilmycin. The other 25 eyes (group 2) received 1 mg betamethasone disodium phosphate and 250 mg piperacillin as a subconjunctival injection. The eyes were then taped closed. Inflammatory parameters (anterior chamber flare, fibrin, folds of Descemet's membrane, corneal edema) and tolerability of the delivery system (pain, itching) were evaluated 24 h after surgery. None of the patients lost the shield and the collagen devices were well tolerated. Groups 1 and 2 showed no significant differences in the parameters considered. There was, however, transient, slight diffuse superficial corneal edema in 24% of group 1 and 4% of group 2, raising the question of inadequate oxygen transmission through collagen shields under closed lids. The results suggest that collagen shields used with the right solution have no significant adverse effect and may be a less invasive alternative to subconjunctival injection.

Abstract
A 28-year-old woman with toxemia during the 34th week of pregnancy complained of visual loss in one eye. Two weeks after abruptio placentae and delivery a retinal pigment epithelium (RPE) tear which presumably followed a RPE detachment (PED) was found in the macular region of the right eye. Visual acuity was 0.8 at the time of diagnosis but was 1.0 in both eyes one year after the delivery. Some authors have described peculiar choroidal lesions associated with central serous chorioretinopathy (CSC) in pregnancy and ischemic exudative choroidal lesions during severe toxemia. However, the findings we describe are highly unusual, indicating that the mechanisms of choroidal and RPE pathology are still poorly understood. We also demonstrate that a pathological tear following toxemia of pregnancy is compatible with good acuity in spite of the anatomical damage.

Abstract
Intrinsic foot muscles (IFM) are a crucial component within the human foot. Investigating their functioning can help understand healthy and pathological behaviour of foot and ankle, fundamental for everyday activities. Recording muscle activation from IFM has been attempted with invasive techniques, mainly investigating single muscles. Here we present a novel methodology, to investigate the feasibility of recording physiological surface EMG (sEMG) non-invasively and quantify patterns of activation across the whole plantar region of the foot. sEMG were recorded with a 13 × 5 array from the sole of the foot (n = 25) during two-foot stance, two-foot tiptoe and anterior/posterior sways. Physiological features of sEMG were analysed. During anterior/posterior epochs within the sway task, sEMG patterns were analysed in terms of signal amplitude (intensity) and structure (Sample Entropy) distribution, by evaluating the centre of gravity (CoG) of each topographical map. Results suggest signals are physiological and not affected by loading. Both amplitude and sample entropy CoG coordinates were grouped in one region and overlapped, suggesting that the region with highest amplitude corresponds with the most predictable signal. Therefore, both spatial and temporal features of IFM activation may be recorded non-invasively, providing opportunity for more detailed investigation of IFM function in healthy and patient populations.

Abstract
In linac-driven free-electron lasers, colliders, and energy recovery linacs, a common way to compress the electron bunch to kiloampere level is based upon the implementation of a magnetic dispersive element that converts particle energy deviation into a path-length difference. Nonlinearities of such a process are usually compensated by enabling a high harmonic rf structure properly tuned in amplitude and phase. This approach is however not straightforward, e.g., in C-band and X-band linacs. In this Letter we demonstrate that the longitudinal self-induced field excited by the electron beam itself is able to linearize the compression process without any use of high harmonic rf structure. The method is implemented at the FERMI linac, with the resulting high quality beam used to drive the seeded free-electron laser during user experiments.

Abstract
Single-photon laser-enabled Auger decay (spLEAD) is predicted theoretically [B. Cooper and V. Averbukh, Phys. Rev. Lett. 111, 083004 (2013)PRLTAO0031-900710.1103/PhysRevLett.111.083004] and here we report its first experimental observation in neon. Using coherent, bichromatic free-electron laser pulses, we detect the process and coherently control the angular distribution of the emitted electrons by varying the phase difference between the two laser fields. Since spLEAD is highly sensitive to electron correlation, this is a promising method for probing both correlation and ultrafast hole migration in more complex systems.

Abstract
Spontaneous dissection of cervical arteries (sCAD) is a major cause of ischemic stroke in young patients, with an incidence varying from 1.7 to 3/100,000/year for extracranial internal carotid artery (ICAD) and 1 to 1.9/100,000/year for extracranial vertebral artery (VAD). Reliable epidemiological data on stroke incidence related to sCAD are scarce in Italy. This study aims to evaluate the incidence, clinical features, and outcome of cerebrovascular events related to sCAD and spontaneous intracranial arteries dissections (sIAD) in the city of Pisa (Italy). We retrospectively analyzed consecutive patients admitted between December 1997 and June 2015 with a diagnosis of stroke, TIA, or Bernard-Horner syndrome due to acute cervical or intracranial artery dissection. Considering that our hospital collects presumptively all patients hospitalized with sCAD coming from the referral geographical area, data may provide a good approximation to real incidence of sCAD in our population. Clinical and radiological features, acute treatment and outcome were collected. Seventy-seven cases were included (mean age 48.1±10.4 years, range 23-77,72.7% males), 66 residents in the district of Pisa. Crude incidence rate of cerebrovascular events due to intra or extracranial dissection was 1.88/100,000/year. The incidence of ICAD was 0.80/100,000/year and 0.43/100,000/year for VAD. Stroke occurred in 76.6% of patients. VAD was more prone to cause ischemic stroke and present with cervical pain or focal signs (p < 0.01) than ICAD group, which had older age at onset. sIAD were more frequent in the posterior circle (p = 0.01) and more associated with ischemic lesions. A good outcome (mRS 0-2) was observed in 79% of patients. This is the first epidemiological attempt to investigate impact of sCAD and sIAD in Italy.

Abstract
Background COPD is one of the leading causes of morbidity and mortality. Pharmacotherapy improves quality of life and reduces exacerbations although low adherence with prescribed treatments may represent a barrier to optimal disease management. The first objective of this paper is to report the distribution of COPD patients according to GOLD categories, in a sample of patients from a cohort study in an area of the Latium region in Italy. The second objective is to evaluate the agreement between the distributions of severity obtained from the HCPs and the experts included in the study board (Board). Methods COPD patients were given a card to collect demographic and clinical data at baseline. Information in those cards was independently evaluated by HCPs and Board to include each patient into one of the four GOLD categories. Results In a sample of 187 stable COPD patients, 59% male, mean age 70 year, the distribution of GOLD categories according to the Board was: 6% A, 34% B, 2% C, and 58% D. A discrepancy in GOLD classification was observed between the study board and field-based HCPs, regarding more than 50% of the patients, with a clear trend to underestimate the frequency of patients in D level (21%) and to overestimate the frequency in C level (21%). Conclusions These results describe for the first time the distribution of COPD patients in an Italian cohort according to the GOLD categories, with the highest frequencies in levels B and D. The misclassification from HCPs may impact the therapeutic approach and the clinical outcomes.
