Abstract
Computational spectrometry is an emerging field that uses photodetection in conjunction with numerical algorithms for spectroscopic measurements. Compact single photodetectors made from layered materials are particularly attractive since they eliminate the need for bulky mechanical and optical components used in traditional spectrometers and can easily be engineered as heterostructures to optimize device performance. However, such photodetectors are typically nonlinear devices, which adds complexity to extracting optical spectra from their response. Here, we train an artificial neural network to recover the full nonlinear spectral photoresponse of a single GeSe-InSe p-n heterojunction device. The device has a spectral range of 400 to 1100 nm, a small footprint of ~25 × 25 square micrometers, and a mean reconstruction error of 2 × 10-4 for the power spectrum at 0.35 nanometers. Using our device, we demonstrate a solution to metamerism, an apparent matching of colors with different power spectral distributions, which is a fundamental problem in optical imaging.

Abstract
The hippocampus plays a critical role in the formation of declarative memories, and hippocampal damage leads to significant impairments in new memory formation. Drawing can serve as a form of multi-modal encoding that improves declarative memory performance relative to other multimodal encoding strategies such as writing. We examined whether, and to what extent, patients with hippocampal damage could benefit from the mnemonic strategy of drawing. Three patients with focal hippocampal damage, and one patient with both hippocampal and cortical lesions, in addition to 22 age-, sex-, and education-matched controls, were shown a list of words one at a time during encoding and instructed to either draw a picture or repeatedly write each word for 40 s. Following a brief filled delay, free recall and recognition memory for words from both encoding trial types were assessed. Controls showed enhanced recall and recognition memory for words drawn versus those that were written, an effect that was even more pronounced in patients with focal hippocampal damage. By contrast, the patient with both hippocampal and cortical lesions showed no drawing-mediated boost in either recall or recognition memory. These findings demonstrate that drawing is an effective encoding strategy, likely accruing from the engagement of extra-hippocampal processes including the integration of cortical-based motor, visual, and semantic processing, enabling more elaborative encoding.

Abstract
Abstract
The Valve-in-Valve (ViV) technique is an emerging alternative for the treatment of bioprosthetic structural valve deterioration (SVD) in the mitral position. We report on intermediate-term outcomes of patients with symptomatic SVD in the mitral position who were treated by transcatheter mitral valve-in-valve (TM-ViV) implantation during the years 2010–2019 in our center. Three main outcomes were examined during the follow-up period: NYHA functional class, TM-ViV hemodynamic data per echocardiography, and mortality. Our cohort consisted of 49 patients (mean age 77.4±10.5 years, 65.3% female). The indications for TM-ViV were mainly for regurgitant pathology (77.6%). All 49 patients were treated with a balloon-expandable device. The procedure was performed via transapical access in 17 cases (34.7%) and transfemoral vein / trans-atrial septal puncture in 32 cases (65.3%). Mean follow-up was 4.4±2.0 years. 98% and 91% of patients were in NYHA I/II at 1 and 5 years respectively. Mitral regurgitation was ≥ moderate in 86.3% of patients prior to the procedure and this decreased to 0% (p<0.001) following the procedure and was maintained over 2 years follow-up. The mean trans-mitral valve gradients decreased from pre-procedural values of 10.1±5.1mmHg to 7.0±2.4mmHg at one month following the procedure (p=0.03). Mortality at one year was 16% (95%, CI 5–26) and 35% (95%, CI 18–49) at 5 years. ViV in the mitral position offers an effective and durable treatment option for patients with SVD at high surgical risk.

Abstract
Abstract
Background
Accumulated experience combined with technological advancements in the field of complex percutaneous coronary intervention (C-PCI), have led to a gradual increase in both quantity and complexity of PCI procedures over the last 20 years. Despite the amount and frequency of these complex interventions, data regarding outcomes is lacking.
Methods
The study was based on a prospective registry of 20,301 consecutive procedures with a follow up of at least 1 year. C-PCIs were defined as at least one of the following: Chronic total occlusion (CTO), left main (LM), bifurcation or saphenous vein graft (SVG) PCI. We compared trends during four different time periods (2008–2010, 2011–2013, 2014–2016, 2017–2019). Endpoints included mortality and major adverse cardiac events [MACE: death, repeat myocardial infarction (re-MI), and target vessel revascularization (TVR)] at 1 year.
Results
The rate of C-PCI procedures has risen significantly since 2017 (p<0.01), driven mainly by bifurcation and LM interventions (p<0.01). At 1-year, rates of death (p<0.001), re-MI (p<0.001), TVR (p=0.001) and MACE (p<0.001), were all significantly higher in the C-PCI group, as compared to the non-complex group. Rates of TVR (p=0.01) and MACE (p<0.001) at 1-year, were significantly higher in the C-PCIs which were performed between 2008–2010 and 2011–2013, as compared to C-PCIs performed between 2014–2016 and 2017–2019. Death rates did not significantly differ between C-PCI periods.
Conclusions
Although frequency of C-PCIs is on the rise, overall outcomes become increasingly better, as compared to earlier periods. Unfortunately, this has not translated into a decrease in mortality.

Abstract
Applying direct growth and deposition of optical surfaces holds great promise for the advancement of future nanophotonic technologies. Here, we report on a chemical vapor deposition (CVD) technique for depositing amorphous selenium (a-Se) spheres by desorption of selenium from Bi2Se3 and re-adsorption on the substrate. We utilize this process to grow scalable, large area Se spheres on several substrates and characterize their Mie-resonant response in the mid-infrared (MIR) spectral range. We demonstrate size-tunable Mie resonances spanning the 2-16 μm spectral range for single isolated resonators and large area ensembles. We further demonstrate strong absorption dips of up to 90% in ensembles of particles in a broad MIR range. Finally, we show that ultra-high-Q resonances arise in the case where Se Mie-resonators are coupled to low-loss epsilon-near-zero (ENZ) substrates. These findings demonstrate the enabling potential of amorphous Selenium as a versatile and tunable nanophotonic material that may open up avenues for on-chip MIR spectroscopy, chemical sensing, spectral imaging, and large area metasurface fabrication.

Abstract
BACKGROUND Recent studies conducted in several OECD countries have shown that chronic exposure to elevated levels of air pollutants (especially PM2.5, PM10 and NOx), might negatively impact COVID-19 morbidity and mortality rates. The aim of this study was to examine the association between chronic exposure to air pollution in Israeli cities and towns, their demographic and socioeconomic status, and COVID-19 morbidity, during the three local morbidity waves. METHODS We examined the associations between: (a) annual average concentrations of NOx, CO, PM10, PM2.5 and SO2 in 2016-2019, and demographic and socioeconomic parameters, and (b) COVID-19 positive cases in 279 Israeli cities and towns, in the four state-wide morbidity peaks: 1st wave peak: March 31st, 2020; 2nd wave peaks: July 24th and September 27th, 2020, and the 3rd wave peak: January 17th, 2021, which occurred after the beginning of the nationwide vaccination campaign. These associations were calculated using both Spearman correlations and multivariate linear regressions. RESULTS We found statistically significant positive correlations between the concentrations of most pollutants in 2016-19 and COVID-19 morbidity rate at the first three timepoints but not the 4th (January 17th, 2021). Population density and city/town total population were also positively associated with the COVID-19 morbidity rates at these three timepoints, but not the 4th, in which socioeconomic parameters were more dominant - we found a statistically significant negative correlation between socioeconomic cluster and COVID-19 morbidity. In addition, all multivariate models including PM2.5 concentrations were statistically significant, and PM2.5 concentrations were positively associated with the COVID-19 morbidity rates in all models. CONCLUSIONS We found a nationwide association between population chronic exposure to five main air pollutants in Israeli cities and towns, and COVID-19 morbidity rates during two of the three morbidity waves experienced in Israel. The widespread morbidity that was related to socioeconomic factors during the 3rd wave, emphasizes the need for special attention to morbidity prevention in socioeconomically vulnerable populations and especially in large household communities. Nevertheless, this ecological study has several limitations, such as the inability to draw conclusions about causality or mechanisms of action. The growing body of evidence, regarding association between exacerbated COVID-19 morbidity and mortality rates and long-term chronic exposure to elevated concentrations of air pollutants should serve as a wake-up call to policy makers regarding the urgent need to reduce air pollution and its harmful effects.

Abstract
We investigated the nature of graphene surface doping by zwitterionic polymers and the implications of weak in-plane and strong through-plane screening using a novel sample geometry that allows direct access to either the graphene or the polymer side of a graphene/polymer interface. Using both Kelvin probe and electrostatic force microscopies, we observed a significant upshift in the Fermi level in graphene of ∼260 meV that was dominated by a change in polarizability rather than pure charge transfer with the organic overlayer. This physical picture is supported by density functional theory (DFT) calculations, which describe a redistribution of charge in graphene in response to the dipoles of the adsorbed zwitterionic moieties, analogous to a local DC Stark effect. Strong metallic-like screening of the adsorbed dipoles was observed by employing an inverted geometry, an effect identified by DFT to arise from a strongly asymmetric redistribution of charge confined to the side of graphene proximal to the zwitterion dipoles. Transport measurements confirm n-type doping with no significant impact on carrier mobility, thus demonstrating a route to desirable electronic properties in devices that combine graphene with lithographically patterned polymers.

Abstract
Abstract
Background
Acute kidney injury (AKI) is a complication of percutaneous coronary intervention (PCI), known to increase rates of adverse medical events. We aimed to identify the optimal definition of AKI in predicting of adverse cardiovascular outcomes and mortality post PCI.
Methods
From a large registry of patients undergoing PCI between 2006–2018 (n=25,690) at two hospitals, consecutive patients were assessed for the presence of AKI according to four different definitions: a relative elevation of ≥25% or ≥50%; or an absolute elevation of ≥0.3 mg/dL or ≥0.5 mg/dL in serum creatinine at 48 hours post PCI. We assessed the calculated rates of AKI according to the different definitions. The discriminant capacity for 30-day and 1-year mortality and MACE (MACE: all-cause death, myocardial infarction, target-vessel revascularization and coronary artery bypass graft surgery) of each definition was calculated using ROC curves and AUCs.
Results
Data of 15,153 patients was available for final analysis. Rates of AKI were 12.1%, 3.2%, 8.1% and 3.9% according to the four definitions, respectively. The discriminant capacity of adverse outcomes was highest among those defined as AKI according to the third definition - an absolute elevation of ≥0.3 mg/dL in serum creatinine with an AUC of 0.82 (95% CI 0.80–0.84) for 30-day mortality (P value = 0.036) and an AUC of 0.78 (CI 0.76–0.79) for 30 days MACE.
Conclusions
An absolute elevation of ≥0.3 mg/dL in serum creatinine 48 hours post PCI predicts overall mortality and MACE most accurately.

Abstract
Abstract
Background
Right heart catheterization (RHC) and echocardiography are both routinely used for pulmonary hypertension (PH) assessment in LT candidates, although this is not mandatory according to guidelines. We aim to describe the correlation between the pulmonary artery systolic pressure (PASP) measured by echocardiography to that measured by RHC in this population.
Methods
From a retrospective registry of 461 LT candidates, undergoing RHC between 2015–2019, 393 consecutive patients were assessed for the presence of pulmonary hypertension according to two methods – echocardiography and RHC. The primary outcome was the correlation between the estimated PASP measured by echocardiography to that measured by RHC. Secondary outcome was the accuracy of the echocardiographic assessment of PH.
Results
Patients were predominantly males (63.6%) with a mean age of 61.46±8.33y. The two most common etiologies for lung failure were interstitial lung disease or pulmonary fibrosis (52.2%) and chronic obstructive pulmonary disease (30.5%). Estimated PASP as measured by echocardiography was available in 89.31% of the patients, with a mean value of 49.5±20.02 mmHg. Mean PASP measured by RHC was 42.47±17.96 mmHg. The correlation between the two measurements was moderate (Pearson's correlation: r=0.609, p<0.01). The accuracy of the echocardiographic estimation of PASP was poor with >10 mmHg differences between the two values in 79.9% of the patients.
Conclusions
In the pre-surgical evaluation of LT candidates, echocardiographic estimation of PASP has moderate correlation with the PASP measured by RHC and relatively poor accuracy.

Abstract
Introduction
The Valve-in-Valve (ViV) technique is an established alternative for the treatment of structural bioprosthetic valve deterioration (SVD). Data describing the long term follow up of patients treated with this approach is scarce. We report on our long-term follow up outcomes of patients with SVD in the Aortic position treated with ViV.
Methods
Included were patients with symptomatic SVD in the aortic position valve who were treated by Valve in valve transcatheter aortic valve implantation (ViV-TAVI) during the years 20102019 in our center. Three main outcomes were examined during follow up: NYHA functional class, hemodynamic of the VIV-TAVI per echocardiography, and overall mortality.
Results
Our cohort consisted of 84 patients (mean age 78.8±8.9 years). The indications for aortic ViV were: SVD isolated aortic stenosis in 37.6%, SVD isolated aortic regurgitation in 42.2% and combined valve pathology in 20.0%. Self-expandable and balloon-expandable devices were used in 73 (85.9%) and 12 (14.1%), respectively. Average time of follow up was 3.74±2.4 years. 95% and 91% of patients were in NYHA functional class I/II at 1 and 5 year follow up respectively. At one year the mean trans-aortic valve pressure was 15.3±9.3 and rates of ≥ moderate aortic regurgitation were 3.7%. Survival was 91.4% (95% CI 85.6–97.7) at one year and 79.5% (95% CI 70.2–90.0) at 3 years.
Conclusion
ViV in the aortic position offers an effective and durable treatment option for patient with SVD, with low rates of all-cause mortality, excellent hemodynamic and improved functional capacity at 3 years follow up.

Abstract
Abstract
Background
Invasive angiography with subsequent revascularization is a widely used treatment method in patients with coronary heart disease. Although biodegradable polymer drug eluting stents (BP-DES) have been used for almost a decade now, clinical trials regarding their long-term outcomes are both sparse and inconsistent. We aimed to compare the long-term outcomes of patients undergoing percutaneous coronary intervention (PCI) with BP-DES versus durable polymer drug eluting stents (DP-DES).
Methods
Among 11,517 PCIs with second generation drug eluting stents preformed in our institution between 2007 and 2019, we identified 8042 procedures performed using DP-DES and 3475 using BP-DES. The primary outcome was the composite of all-cause mortality, recurrent myocardial infarction (re-MI), target vessel revascularization (TVR) and coronary artery bypass grafting (CABG). Propensity score matching was used to create a well-balanced cohort.
Results
Mean follow up was 4.8 years. Of the 3,413 matched pairs, 21% were females, and the mean age was 66. At one year, the primary outcome occurred in 9.6% patients versus 8.3% (p=0.05), and TVR rate was 4.1% versus 3% (p=0.005) in patients with DP-DES and BP-DES respectively. Within 5 years, the primary outcome occurred in in 24.9% versus 24.8% (p=0.83), and the rate of TVR was 9.8% versus 9.1% (p=0.07) in patients with DP-DES and BP-DES respectively.
Conclusions
Similar rates of the composite outcome were observed throughout the entire follow-up. TVR rates were lower in the DP-DES group at 1-year but equalized within 5 years.

Abstract
Abstract
Introduction
Based on data from randomized controlled trials, both American and European guidelines recommend treating acute coronary syndrome (ACS) patients with second generation P2Y12 inhibitors.1,2 Direct head-to-head comparison of these agents was scarce until the recent publication of the ISAR-REACT-5 study which demonstrated the superiority of the Irreversible thienopyridine type P2Y12 inhibitor (prodrug) over the reversible P2Y12 inhibitor in terms of 1-year composite of death, myocardial infarction (MI), and stroke.3,4,5 Given the unexpected outcomes of this trial, we sought to perform a comparison of ticagrelor and prasugrel in real-life ACS patients.
Purpose
To compare the outcomes of ACS (acute coronary syndrome) patients undergoing in-hospital PCI (percutaneous coronary intervention) treated with the Irreversible thienopyridine type P2Y12 inhibitor (prodrug) versus the reversible P2Y12 inhibitor.
Methods
ACSIS (Acute Coronary Syndrome in Israel) is a national ACS snapshot survey conducted in all 25 cardiology departments in Israel since 2000 over a two-month period, every two to three years. Both the Irreversible thienopyridine type P2Y12 inhibitor (prodrug) and the reversible P2Y12 inhibitor were commercially introduced in Israel in 2010. We therefore considered patients enrolled in ACSIS surveys 2010–2018 for the present analysis.
Results
Among 7,233 patients enrolled to the ACSIS (Acute Coronary Syndrome in Israel) registry between 2010 and 2018, we identified 1133 eligible patients treated with the Irreversible thienopyridine type P2Y12 inhibitor (prodrug) and 825 with the reversible P2Y12 inhibitor. In hospital complication rates, including rates of stent thrombosis, were roughly similar between groups. Compared to the reversible P2Y12 inhibitor, the Irreversible thienopyridine type P2Y12 inhibitor (prodrug) was associated with lower 1-year death in ST-elevation myocardial infarction (STEMI) patient compared to non-ST-elevation ACS (NSTE-ACS) patients (p for interaction 0.03). In propensity score matched STEMI patients (502 receiving the Irreversible thienopyridine type P2Y12 inhibitor (prodrug), 251 the reversible P2Y12 inhibitor) 30-day re-hospitalization rate (p<0.05), 30-day MACE (the composite of death, MI, stroke, urgent revascularization; p=0.006), and 1-year mortality rates (p=0.08) were higher in the the reversible P2Y12 inhibitor group compared to the the Irreversible thienopyridine type P2Y12 inhibitor (prodrug) group; In NSTE-ACS patients, outcomes were not impacted by drug choice.
Conclusion
The Irreversible thienopyridine type P2Y12 inhibitor (prodrug) was more effective than the reversible P2Y12 inhibitor in STEMI patients, but not in NSTE-ACS patients.

Abstract
Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare benign vascular proliferation, which manifests as characteristic red nodules and papules, mostly located on the scalp and periauricular regions. Patients seek treatment for both aesthetic and functional reasons, as lesions may ulcerate, bleed and itch. Many therapeutic approaches have been reported, with variable success, and relapse remains a troublesome issue. The aim of this study was to report our experience treating ALHE using percutaneous ethanol sclerotherapy (PES). We present a retrospective case series of three patients treated with PES (1-2 treatment sessions each). All patients had tried and failed other treatments prior to this intervention, but following PES treatment, all patients demonstrated significant improvement, which was sustained at follow-up (range 8-17 months after first treatment). Adverse effects were tolerable and transient. This case series demonstrates PES as a promising treatment for recalcitrant ALHE.

Abstract
Recent data show an interaction between COVID-19 and nicotine and indicate the need for an assessment of transdermal nicotine use in non-smokers. Assessments have been conducted into the short-term cognitive effects of nicotine and into diseases such as Parkinson's, Tourette syndrome, ADHD or ulcerative colitis. METHODS Analyses of nicotine administration protocols and safety were conducted after reviewing Medline and Science Direct databases performing a search using the words [transdermal nicotine] AND [non-smoker] AND selected diseases. RESULTS Among 298 articles identified, there were 35 reviewed publications reporting on 33 studies of non-smokers receiving transdermal nicotine for >48hours. In the 16 randomized trials, 7 crossover, 1 case/control and 9 open studies patients received an initial nicotine dose of between 2.5mg and 15mg/day. In 22 studies, daily doses increased by 2 to 7 steps in 3 to 96 days until the dose was between 5mg and 105mg/day. The target nicotine dose was 19.06±20.89mg/day. The 987 non-smokers (534 never-smokers, 326 ex-smokers and 127 classified as "non-smokers") received or did not receive nicotine. The most common side-effects were nausea and skin itching. Forty-three (7.1%) non-smokers stopped treatment because of an adverse event of nicotine. No hospitalization related to nicotine side-effects were reported. CONCLUSION Despite a relatively safe tolerance profile, transdermal nicotine therapy in non-smokers can only be used in clinical trials. There is a lack of formal assessment of the potential risk of developing a tobacco addiction. This review offers baseline data to set a transdermal nicotine protocol for non-smokers with a new purpose.

Abstract
BACKGROUND Exposure to ambient air pollution is related to 4.2 million premature deaths per year worldwide and is associated with a variety of adverse health outcomes, such as respiratory and cardiovascular morbidity. Furthermore, exposure to air pollution can increase human sensitivity to respiratory pathogens via damage to the respiratory tract or via airborne transmission on the surface of particulate matter, and might be an additional factor influencing COVID-19 morbidity and mortality rates. The aim of this study was to examine the association between populations' exposure to air pollution and the morbidity and mortality rates from COVID-19. METHODS We examined the association between population-weighted long-term exposure to PM2.5 and NOx, and the morbidity and mortality over time following the detection of the first COVID-19 positive case in 36 OECD countries. Pearson and Spearman correlations between daily COVID-19 morbidity and mortality (Jan-Jun 2020) on the 10th, 20th, 40th, 60th and 80th days since first confirmed case in the country, and demographic, health, economic, and environmental data were calculated. Multivariate linear regression were used to examine the associations between demographic, health, economic and air pollution features and the rate of confirmed cases and deaths on the 60th and 80th days following the first confirmed case. RESULTS PM2.5 concentrations in 2015-2017 were positively correlated with COVID-19 morbidity and mortality on the 10th, 20th, 40th and 60th days since the first confirmed case in all countries. NOx concentrations in 2015-2017 and country's density (population/Km2) were positively correlated with COVID-19 morbidity and mortality on the 60th day. All multivariate linear regressions consisting PM2.5 concentrations models were statistically significant. Our models also emphasize the importance of the relative number of hospital beds in decreasing the morbidity and mortality of COVID-19. CONCLUSIONS The adverse health outcomes stemming from long-term exposure to various air pollutants has long been known to the scientific community. According to our results and previously published studies, it appears that long-term exposure to air pollutants concentrations exceeding WHO guidelines, such as PM2.5 and NOx, might exacerbate morbidity and mortality rates from COVID-19. These results should raise a red flag globally among decision makers about the urgent need to reduce air pollution and its harmful effects.

Abstract
Graphene holds promise for thin, ultralightweight, and high-performance nanoelectromechanical transducers. However, graphene-only devices are limited in size due to fatigue and fracture of suspended graphene membranes. Here, a lightweight, flexible, transparent, and conductive bilayer composite of polyetherimide and single-layer graphene is prepared and suspended on the centimeter scale with an unprecedentedly high aspect ratio of 105 . The coupling of the two components leads to mutual reinforcement and creates an ultrastrong membrane that supports 30 000 times its own weight. Upon electromechanical actuation, the membrane pushes a massive amount of air and generates high-quality acoustic sound. The energy efficiency is ≈10-100 times better than state-of-the-art electrodynamic speakers. The bilayer membrane's combined properties of electrical conductivity, mechanical strength, optical transparency, thermal stability, and chemical resistance will promote applications in electronics, mechanics, and optics.

Abstract
BACKGROUND From a dermatologist's perspective, there are four major types of cutaneous porphyrias (CPs): porphyria cutanea tarda (PCT), erythropoietic protoporphyria (EPP), variegate porphyria (VP) and hereditary coproporphyria (HCP). Scarce data are available regarding the epidemiology of CPs. OBJECTIVES To describe the epidemiology of CPs in Israel, including distribution, incidence and prevalence rates of major types. METHODS This retrospective study includes all patients who were diagnosed with CPs between the years 1988-2018. It is based on data from Israel's National Service for the Biochemical Diagnoses of Porphyrias, and Israeli patients' nationwide electronic medical charts. Incidence and prevalence rates were calculated. RESULTS Of 173 patients with CPs diagnosed during a 30-year period, 65 (38%) had VP, 62 (36%) had PCT, 31 (18%) had HCP and 15 (9%) had EPP; with incidence rates of 0.29, 0.30, 0.17, 0.07, and prevalence rates of 6.3, 4.8, 2.9, 1.6, respectively, per million population. Characteristics of patients with PCT differed from those with other CPs with regard to lack of family history, older mean age at diagnosis [51 vs. 36 (VP), 35 (HCP) and 25 (EPP) years] and male predominance (81% vs. similar distribution). All patients with PCT were diagnosed at adulthood, while 20%, 19% and 15% of patients with VP, HCP and EPP, respectively, were diagnosed during childhood or adolescence. CONCLUSIONS Variegate porphyria and PCT were found to be the most prevalent in Israel; however, CPs might be underdiagnosed, thus dermatologists' awareness of these rare disorders is highly important.

Abstract
BACKGROUND Solar urticaria (SU) is a rare photodermatosis causing a significant impact on patients' quality of life (QoL), and treatment is often challenging. AIM To analyse clinical experience with a tailored stepwise therapeutic approach. METHODS A retrospective cohort design was used. Patients with suspected SU underwent laboratory investigations and photoprovocation. Those with a high minimal urticaria dose (MUD) were treated with a single antihistamine (protocol 1), and those with a lower MUD received three types of antihistamines (protocol 2); both protocols included a leucotriene receptor antagonist (LRA). In cases of failure, treatment was switched to omalizumab at doses of < 300 mg/month with incremental dosage increases as necessary (monthly dose range, 150-600 mg/month). Symptom relief and photoprovocation under treatment were evaluated. RESULTS In total, 30 patients (10 men, 20 women) were enrolled. Most (87%) were sensitive to visible light (1-70 J/cm2 ) with or without extension to ultraviolet A. Of the 30 patients, 23 opted for our stepwise approach: 22 achieved complete remission on protocols 1 or 2 (n = 17) or after switching to omalizumab (n = 5), and another patient achieved partial remission under omalizumab. There were no treatment-related severe adverse effects. CONCLUSIONS Symptoms of SU can be well controlled by treatment with antihistamines and an LRA tailored to the degree of photosensitivity, followed by omalizumab in refractory cases. This has important implications for patient QoL.

Abstract
Abstract
Background: Almost a quarter of older adults in the United States will identify themselves as Hispanic/Latino by 2060. Our group has previously developed and validated a self-administered geriatric assessment tool which can be used to identify functional, psychological, social and cognitive impairments among older patients with various types of cancer. Among English-speaking older adults, completing this tool using paper/pencil or a tablet takes a median of 15-21 minutes (min), with < 10% needing assistance to answer it (Hurria, JOP 2016). However, the utilization of this tool among Spanish-speaking older adults has not been tested. We assessed the feasibility of administering a translated and validated Spanish version of our geriatric assessment tool for older Hispanic women with breast cancer, and identified their preferred format (tablet or paper/pencil).
Methods: Spanish-speaking women aged ≥ 65 years with a diagnosis of breast cancer completed the geriatric assessment twice on the same day. Patients were randomized into 3 groups: paper/pencil twice; tablet and paper/pencil in random order; and tablet twice. We assessed the proportion of patients requiring assistance to complete the geriatric assessment, the time needed to complete it, and the proportion of patients who thought the geriatric assessment was difficult/very difficult.
Results: 140 older women with breast cancer completed the geriatric assessment twice and were evaluable. Mean age was 71.6 years (SD 5.8), 53% had ≤ 8th grade education, 43% were married, 45% were retired, 32% were homemakers, and 6% were employed. The participants came from 13 different Spanish-speaking countries, although 70% were born in Mexico. For 90%, Spanish was their primary language, and 75% spoke only in Spanish at home. Regarding computer skills, 64% of the patients said they had none. 39% (n = 54) were unable to complete the geriatric assessment on their own; mean time to complete the geriatric assessment was 29 min (range 8-90); and 28% (n = 39) thought the geriatric assessment was difficult/very difficult. The most common reasons for needing assistance were difficulty understanding questions (39%) and visual problems (31%). Patients with ≤ 8th grade education took longer to complete the geriatric assessment (mean 37.2 vs 29.4 min, p < 0.01), and more often needed help completing the assessment (51% vs 19%, p < 0.01) than those with ≥9th grade education. 53% of the participants preferred using a tablet to answer the geriatric assessment, while 47% preferred paper/pencil.
Conclusions: A substantial proportion of Spanish-speaking older women with breast cancer required assistance to complete our self-administered geriatric assessment tool. This may be a consequence of the low educational level we found among this patient population. Tailoring assessments for diverse populations with particular attention to educational level is needed in multicultural settings.

Abstract
A high saturation velocity semiconductor is appealing for applications in electronics and optoelectronics. Thin-film black phosphorus (BP), an emerging layered semiconductor, shows a high carrier mobility and strong mid-infrared photoresponse at room temperature. Here, we report the observation of high intrinsic saturation velocity in 7 to 11 nm thick BP for both electrons and holes as a function of charge-carrier density, temperature, and crystalline direction. We distinguish a drift velocity transition point due to the competition between the electron-impurity and electron-phonon scatterings. We further achieve a room-temperature saturation velocity of 1.2 (1.0) × 107 cm s-1 for hole (electron) carriers at a critical electric field of 14 (13) kV cm-1, indicating an intrinsic current-gain cutoff frequency ∼20 GHz·μm for radio frequency applications. Moreover, the current density is as high as 580 μA μm-1 at a low electric field of 10 kV cm-1. Our studies demonstrate that thin-film BP outperforms silicon in terms of saturation velocity and critical field, revealing its great potential in radio-frequency electronics, high-speed mid-infrared photodetectors, and optical modulators.

Abstract
Abstract
Background: Older adults are less likely to be included in clinical trials leading to the approval of novel cancer treatments. The Institute of Medicine and ASCO have identified therapeutic phase II trials as a key research priority to increase the evidence base for older adults with cancer. While targeted therapies may represent a less toxic option for older patients, few trials have studied their tolerability and efficacy in older adults. Here, we present a phase II study (NCT01273610) of the combination of trastuzumab and lapatinib in older patients with HER2+ metastatic breast cancer (MBC), incorporating geriatric oncology principles in the study design.
Methods: Patients age ≥ 60 years with MBC and any number of prior chemotherapy (CT) lines received trastuzumab (either 4mg/kg loading dose followed by 2mg/kg weekly or 8mg/kg followed by 6mg/kg q/3 weeks) plus lapatinib 1000 mg/m2 daily in 21-day cycles. Patients completed a pre-treatment geriatric assessment including measures of function, comorbidity, cognition, nutrition, and psychosocial status. A toxicity risk score developed for older adults receiving cytotoxic CT was calculated for each patient (Hurria et al. JCO 2011 & 2016). Relationships between tolerability (dose reductions and grade (G) ≥ 3 toxicity attributed to treatment) and risk score analyzed using a log2 transformation were assessed using generalized linear models, Student's t tests, and Fisher's exact test. Response rate (RR) and progression free survival (PFS) were evaluated.
Results: 40 patients (mean age 72 [60-92]) were accrued from 04/11 to 05/15. 25% (n = 10) were ≥ 75 years of age. 65% of patients (n = 26) had HR+ tumors and 35% (n = 14) were receiving ≥ 3rd line treatment. Median number of cycles was 4 (0-28). RR was 23% (n = 9, 95% CI 11-38%; 1 complete, 8 partial). 23% (n = 9) achieved stable disease. PFS was 2.7 months (95% CI 2.5-12). Based on the toxicity risk score, 21% (n = 8), 54% (n = 21), and 26% (n = 10) were at low, intermediate, and high risk. 70% (n = 28) of patients had G ≥ 2 toxicities and 20% (n = 8) G ≥ 3 toxicities. G 2 and 3 diarrhea occurred in 28% (n = 11) and 5% (n = 2) respectively. 5% (n = 2) were hospitalized due to treatment-related toxicity. No G ≥ 3 cardiac toxicities were observed. 23% of patients (n = 9) had treatment delays, and 43% (n = 17) required a lapatinib dose reduction. The mean toxicity risk score was higher in patients who required dose reductions (Student's t: p = 0.02). No statistically significant relationship was found between toxicity risk scores and the presence of G ≥ 3 treatment toxicity (logistic regression: OR = 3.08, 95% CI [0.54, 21.2], p = 0.22).
Conclusions: Among older patients with MBC (79% at intermediate or high risk of G ≥ 3 cytotoxic CT toxicity), trastuzumab and lapatinib were well tolerated, with only 20% experiencing G3 toxicities. The toxicity risk score was not found to be significantly related with treatment toxicity, which may be explained by the very low incidence of G3 events. Patients with a low toxicity risk score were not likely to require a lapatinib dose reduction.

Abstract
The objective was to critically review the data and assess the implications of NexoBrid [NexoBrid-NXB formerly Debrase Gel Dressing-DGD]a in the special field of deep hand burns. Detailed analysis of endpoints in the treatment of hand burn patients was conducted as part of a multi-center, open label, randomized, controlled two-arm study to evaluate the safety and efficacy of NXB enzymatic debridement, comparing it to the current standard of care (SOC). These results were compared to a large cohort of patients treated with NXB in a previous, single arm study. Thirty-one burned hands were treated with NXB and 41 hand burns were in the SOC group. In the NXB group, 4 out of 31 hand burns (12.9%) required some excisional debridement compared to 29 out of the 41 (70.7%) in the SOC group (p<0.0001). Mean percentage of burn wound area excised in the NXB group was 4.4 ± 13.1% compared to 52.0 ± 41.4% in the SOC group (p<0.0001). None of the NXB-treated hands required escharotomy compared to 4 out of the 41 (9.7%) in the SOC group. NXB enzymatic debridement demonstrated a statistically significant reduction in burn wound excision and auto-grafting compared to SOC, and seems to prevent the need for emergency escharotomy. a DGD is produced by MediWound and distributed under the name NexoBrid®.

Abstract
OBJECTIVE To evaluate the association between aberrant right subclavian artery (ARSA), with or without additional risk factors for aneuploidy or ultrasound abnormality, and results of chromosomal microarray analysis (CMA). METHODS This was a multicenter study of fetuses diagnosed with ARSA that underwent genetic analysis by CMA, all samples being analyzed in the same laboratory. Clinical investigation included nuchal translucency measurement, first- and second-trimester maternal serum screening, early and late second-trimester fetal anatomy scans and fetal echocardiography. Comparative genomic hybridization microarray analysis or single-nucleotide polymorphism array technology was used for CMA of DNA samples obtained from amniotic fluid. RESULTS CMA results were available for 63 fetuses with ARSA. In 36 fetuses, ARSA was an isolated finding, and no pathogenic variant was found. Additional ultrasound findings and/or risk factors for aneuploidy were present in 27 fetuses, five of which had pathogenic CMA results. Of these five, trisomy 21 was detected in a fetus with echogenic intracardiac focus (EIF), 22q11 deletion was detected in a fetus with EIF and an increased risk of trisomy 21 of 1:230 from maternal serum screening, 22q11 duplication was detected in a fetus with hypoplastic right kidney and choroid plexus cyst and 22q11 deletion was detected in a fetus with right aortic arch and clubfoot. The fifth fetus had increased nuchal translucency thickness (4 mm) and a ventricular septal defect, and CMA identified both 22q11 deletion and 1q21 duplication. CONCLUSIONS In fetuses with isolated ARSA, an invasive procedure for CMA is not indicated. However, CMA is recommended when additional ultrasound abnormalities or risk factors for aneuploidy are observed. The chromosomal findings in four of the five cases with an abnormal CMA result in our study would not have been detected by standard fetal chromosomal testing. Copyright © 2016 ISUOG.

Abstract
Acne treatment by a mid-infrared laser may be unsatisfactory due to deeply situated acne-affected sebaceous glands which serve as its target. Skin manipulation by vacuum and contact cooling may improve laser-skin interaction, reduce pain sensation, and increase overall safety and efficacy. To evaluate the safety and efficacy of acne treatment using an integrated cooling-vacuum-assisted 1540-nm erbium:glass laser, a prospective interventional study was conducted. It included 12 patients (seven men and five women) suffering from mild-to-moderate acne vulgaris. The device utilizes a mid-infrared 1540-nm laser (Alma Lasers Ltd. Caesarea, Israel), which is integrated with combined cooling-vacuum-assisted technology. An acne lesion is initially manipulated upon contact by a vacuum-cooling-assisted tip, followed by three to four stacked laser pulses (500-600 mJ, 4 mm spot size, and frequency of 2 Hz). Patients underwent four to six treatment sessions with a 2-week interval and were followed-up 1 and 3 months after the last treatment. Clinical photographs were taken by high-resolution digital camera before and after treatment. Clinical evaluation was performed by two independent dermatologists, and results were graded on a scale of 0 (exacerbation) to 4 (76-100 % improvement). Patients' and physicians' satisfaction was also recorded. Pain perception and adverse effects were evaluated as well. All patients demonstrated a moderate to significant improvement (average score of 3.6 and 2.0 within 1 and 3 months, respectively, following last treatment session). No side effects, besides a transient erythema, were observed. Cooling-vacuum-assisted 1540-nm laser is safe and effective for the treatment of acne vulgaris.

Abstract
The response of Grapholita molesta (Busck) males to three-component sex pheromone blends containing a 100% ratio of the major sex pheromone component, (Z)-8-dodecenyl acetate and a 10% ratio of (Z)-8-dodecenol, but with varying ratios of (E)-8-dodecenyl acetate (0.4, 5.4, 10.4, 30.4, and 100.1% E-blends) was tested with populations in eight stone and pome fruit orchards in Europe, Asia, and North and South America. Traps baited with the 5.4% E-blend caught significantly more males than traps with any other blend with all populations. Significantly more males were caught in traps baited with the 10.4% E-blend than in traps with the remaining blends, except with the 0.4% E-blend in Turkey. Significant differences in male moth catches occurred between the other blends with the 0.4>30.4% E-blend, and the 30.4>100.1% E-blend. Male moth catches with the 100.1% E-blend only differed from the hexane control in Chile. No apparent differences were noted to these blends in populations collected from pome or stone fruits. Flight tunnel assays to synthetic blends with a subset of populations were similar to the field results, but the breadth of the most attractive E-blends was wider. Flight tunnel assays also demonstrated a high level of male-female cross-attraction among field-collected populations. Female gland extracts from field-collected populations did not show any significant variation in their three-component blends. The only exceptions in these assays were that long-term laboratory populations were less responsive and attractive, and produced different blend ratios of the two minor components than recently collected field populations.

Abstract
In an effort to develop bottle gourd (Lagenaria siceraria) as a widely adapted rootstock for watermelon grafting, we sought to identify lines with broad resistance to several cucurbit viruses that are economically important in the United States. Preliminary analysis under greenhouse conditions indicated that the currently available commercial watermelon rootstocks were either highly susceptible or somewhat tolerant to one or more viruses. However, in greenhouse screening, several breeding lines of bottle gourd displayed broad-spectrum resistance to four viruses tested, including Zucchini yellow mosaic virus, Watermelon mosaic virus (WMV), Papaya ringspot virus watermelon strain (PRSV-W), and Squash vein yellowing virus. Resistance to PRSV-W and WMV was confirmed through field trials in two consecutive years at two different locations in South Carolina. Two breeding lines (USVL#1-8 and USVL#5-5) with broad-spectrum virus resistance could be useful materials for watermelon rootstock development.

Abstract
Bisphosphonates (BPs) are used intravenously to treat cancer-related conditions for the prevention of pathological fractures. Osteonecrosis of the jaw (BRONJ) is a rare complication reported in 4-15% of patients. We studied, retrospectively, 55 patients with multiple myeloma or Waldenstrom's macroglobulinemia followed up from different haematological departments who developed BRONJ. All patients were treated with BPs for bone lesions and/or fractures. The most common trigger for BRONJ was dental alveolar surgery. After a median observation of 26 months, no death caused by BRONJ complication was reported. In all, 51 patients were treated with antibiotic therapy, and in 6 patients, this was performed in association with surgical debridement of necrotic bone, in 16 with hyperbaric O(2) therapy/ozonotherapy and curettage and in 12 with sequestrectomy and O(2)/hyperbaric therapy. Complete response was observed in 20 cases, partial response in 21, unchanged in 9 and worsening in 3. The association of surgical treatment with antibiotic therapy seems to be more effective in eradicating the necrotic bone than antibiotic treatment alone. O(2) hyperbaric/ozonotherapy is a very effective treatment. The cumulative dosage of BPs is important for the evolution of BRONJ. Because the most common trigger for BRONJ was dental extractions, all patients, before BP treatment, must achieve an optimal periodontal health.

Abstract
The treatment and hospitalization policies in various hospitals in Israel are influenced by injury severity and by the existence or non-existence of a designated burn treatment body. Severely injured burn victims requiring designated burn treatment are referred to one of Israel's five major burn units located in the highest level trauma centres that have an advanced burn treatment infrastructure. This national distribution of burn centres ensures designated treatment availability in various areas according to Israeli demographics, geography, and security threats. Israel does not have an obligatory burn report policy. Implementation of a national burn repository such as that in the USA will be able to give burn treatment specialists in our country a basis for comparison of treatment standards and allow for better care for burn victims. The Israeli Burn Association has a major role in the processes discussed in the manuscript.

Abstract
Defective expression of frataxin is responsible for the degenerative disease Friedreich's ataxia. Frataxin is a protein required for cell survival since complete knockout is lethal. Frataxin protects tumor cells against oxidative stress and apoptosis but also acts as a tumor suppressor. The molecular bases of this apparent paradox are missing. We therefore sought to investigate the pathways through which frataxin enhances stress resistance in tumor cells. We found that frataxin expression is upregulated in several tumor cell lines in response to hypoxic stress, a condition often associated with tumor progression. Moreover, frataxin upregulation in response to hypoxia is dependent on hypoxia-inducible factors expression and modulates the activation of the tumor-suppressor p53. Importantly, we show for the first time that frataxin is in fact increased in human tumors in vivo. These results show that frataxin participates to the hypoxia-induced stress response in tumors, thus implying that modulation of its expression could have a critical role in tumor cell survival and/or progression.

Abstract
BACKGROUND AND PURPOSE Vgf gene expression has been detected in various endocrine and neuronal cells in the gastrointestinal tract. In this study we investigated the pharmacological activity of different VGF-derived peptides. Among these, TLQP-21, corresponding to the 556-576 fragment of the protein was the unique active peptide, and its pharmacological profile was further studied. EXPERIMENTAL APPROACH The effects of TLQP-21 were examined in vitro by smooth muscle contraction in isolated preparations from the rat gastrointestinal tract and, in vivo, by assessing gastric emptying in rats. Rat stomach tissues were also processed for immunohistochemical and biochemical characterization. KEY RESULTS In rat longitudinal forestomach strips, TLQP-21 (100 nmol x L(-1)-10 micromol x L(-1)) concentration-dependently induced muscle contraction (in female rats, EC(50) = 0.47 micromol.L(-1), E(max): 85.7 +/- 7.9 and in male rats, 0.87 micromol x L(-1), E(max): 33.4 +/- 5.3; n = 8), by release of prostaglandin (PG)E(2) and PGF(2a) from the mucosal layer. This effect was significantly antagonized by indomethacin and selective inhibitors of either cyclooxygenase-1 (S560) or cyclooxygenase-2 (NS398). Immunostaining and biochemical studies confirmed the presence of VGF in the gastric neuronal cells. TLQP-21, injected i.c.v. (2-32 nmol per rat), significantly decreased gastric emptying by about 40%. This effect was significantly (P < 0.05) blocked by i.c.v. injection of indomethacin, suggesting that, also in vivo, this peptide acts in the brain stimulating PG release. CONCLUSIONS AND IMPLICATIONS The present results demonstrate that this VGF-derived peptide plays a central and local role in the regulation of rat gastric motor functions.

Abstract
The present review summarizes recent findings on the metabolic and gastroenteric role of the VGF gene and a peptide derived by post-translational cleavage of the VGF pro-hormone, i.e. TLQP-21. The vgf gene is widely expressed through the central nervous system as well as in the peripheral nervous system, in myenteric plexus ganglia and also in the glandular portion of the stomach. A few VGF derived peptide have been shown to possess biological activity, among them TLQP-21 attracted particular interest following its identification within rat nervous system. In particular, recent studies from our and other groups implicated TLQP-21 in both the modulation of energy homeostasis, body weight regulation and neuroendocrine functions as well as in the central control of gut functions. Overall, findings available point to a role for TLQP-21 in negatively affecting the body energy balance.

Abstract
Linkage and association studies in schizophrenia have repeatedly drawn attention to several chromosomal regions and to genes within them. Conflicting patterns of association and the lack of a clear functional significance of the associated variants limit the interpretation of these results. The use of rare pedigrees, where genes with a major effect cause the disorder, has been proven beneficial in studies of other complex disorders. Our objective was to use this advantage by performing a genome wide linkage analysis for schizophrenia in a large, multiplex Israeli Arab pedigree. We genotyped 346 microsatellite markers in 24 pedigree members affected with schizophrenia spectrum disorders and 32 unaffected relatives. Two-point linkage analysis with SUPERLINK demonstrated a LOD score of 2.47 for D20S116 on chromosome 20p13 under an autosomal dominant mode of inheritance. Further fine mapping yielded a two-point LOD score of 2.56 for the adjacent marker D20S193 and narrowed down the linked region to 2-5 cM. A haplotype containing the markers D20S193, D20S889, and D20S116, 0.7 Mb in length, was found to be shared by most affected pedigree members. Genotyping of 43 SNPs in the interval supported these results with a multipoint LOD score of 2.7 around D20S193. We were also able to better define the boundaries of the shared haplotype which contains strong candidate genes for schizophrenia. Our study exemplifies the power of rare and unique pedigrees in drawing attention to novel regions for genetic studies of schizophrenia.

Abstract
OBJECTIVE Biallelic ablation of VGF determines a dwarf phenotype. VGF precursor protein encodes for different biologically active peptides none of which has been related to growth or muscular abnormalities. Here we present the first attempt to fill this gap. We tested the hypothesis that a recently identified VGF-derived peptide, TLQP-21, shown to centrally modulate metabolic functions, could also modulate growth hormone (GH)-axis and muscle strength. DESIGN Adult male mice were chronically icv injected with TLQP-21 (15 microg/day for 14 days). Physiological, molecular and behavioral parameters related to the GH/IGF-1-axis were investigated. RESULTS Except for a reduction in the soleus weight, TLQP-21 did not affect GH/IGF-1-axis mediators, muscle strength and muscle weight. CONCLUSIONS Results collected exclude a role for TLQP-21 in modulating the GH/IGF1-axis and muscle functions. VGF-derived peptides involved in the dwarf phenotype of VGF-/- mice have to be identified yet.
