Abstract
Quantum sensors leverage matter's quantum properties to enable measurements with unprecedented spatial and spectral resolution. Among these sensors, those utilizing nitrogen-vacancy (NV) centers in diamond offer the distinct advantage of operating at room temperature. Nevertheless, signals received from NV centers are often complex, making interpretation challenging. This is especially relevant in low magnetic field scenarios, where standard approximations for modeling the system fail. Additionally, NV signals feature a prominent noise component. In this Letter, we present a signal-to-image deep learning model capable of automatically inferring the number of nuclear spins surrounding a NV sensor and the hyperfine couplings between the sensor and the nuclear spins. Our model is trained to operate effectively across various magnetic field scenarios, requires no prior knowledge of the involved nuclei, and is designed to handle noisy signals, leading to fast characterization of nuclear environments in real experimental conditions. With detailed numerical simulations, we test the performance of our model in scenarios involving varying numbers of nuclei, achieving an average error of less than 2 kHz in the estimated hyperfine constants.

Abstract
We propose quantum neural networks that include multi-qubit interactions in the neural potential leading to a reduction of the network depth without losing approximative power. We show that the presence of multi-qubit potentials in the quantum perceptrons enables more efficient information processing tasks such as XOR gate implementation and prime numbers search, while it also provides a depth reduction to construct distinct entangling quantum gates like CNOT, Toffoli, and Fredkin. This simplification in the network architecture paves the way to address the connectivity challenge to scale up a quantum neural network while facilitating its training.

Abstract
Ensembles of nitrogen-vacancy (NV) centers are used as sensors to detect nuclear magnetic resonance signals from micron-sized samples at room temperature. In this scenario, the regime of large magnetic fields is especially interesting as it leads to a large nuclear thermal polarization-thus, to a strong sensor response even in low concentration samples-while chemical shifts and J couplings become more accessible. Nevertheless, this regime remains largely unexplored owing to the difficulties of coupling NV-based sensors with high-frequency nuclear signals. In this Letter, we circumvent this problem with a method that maps the relevant energy shifts in the amplitude of an induced nuclear spin signal that is subsequently transferred to the sensor. This stage is interspersed with free-precession periods of the sample nuclear spins where the sensor does not participate. Thus, our method leads to high spectral resolutions ultimately limited by the coherence of the nuclear spin signal.

Abstract
We present an invariant-based quantum control scheme leading to a highly monochromatic ion beam from a Paul trap. Our protocol is implementable by supplying the segmented electrodes in the trap with voltages of the order of volts. This mitigates the impact of fluctuations in previous designs and leads to a low-dispersion beam of ions. Moreover, our proposal does not rely on sympathetically cooling ions, which bypasses the need of loading different species in the trap-namely, the propelled ion and, e.g. a [Formula: see text] to exert sympathetic cooling-significantly incrementing the repetition rate of the launching procedure. Our scheme is based on an invariant operator linear in position and momentum, which enables us to control the average extraction energy and the outgoing momentum spread. In addition, we propose a sequential operation to tailor the transversal properties of the beam before the ejection to minimize the impact spot and to increase the lateral resolution of the implantation. This article is part of the theme issue 'Shortcuts to adiabaticity: theoretical, experimental and interdisciplinary perspectives'.

Abstract
OBJECTIVE To evaluate: (i) safety, (ii) feasibility, and medium-term (iii) oncological and (iv) functional outcomes of salvage radical prostatectomy (sRP) for recurrent localised prostate cancer (PCa) following initial focal therapy using irreversible electroporation (IRE). PATIENTS AND METHODS An international, multicentre and retrospective analysis of prospectively collected data of patients that underwent sRP for recurrent localised PCa after initial primary IRE treatment. Data were reported on (i) surgical complications, (ii) feasibility of sRP reported by surgeons, (iii) time interval between IRE and sRP and pathology results, and (iv) urinary continence, erectile function, and quality of life. RESULTS In four participating centres, a total of 39 patients with a median (interquartile range [IQR]) age 64 (60-67) years were identified. No serious adverse events occurred during or following sRP and surgery was deemed feasible without difficulties. The median (IQR) time to recurrence following IRE was 14.3 (9.1-38.8) months. Pathology results showed localised disease in 21 patients (53.8%) and locally-advanced disease in 18 (46.2%). Positive surgical margins (PSMs) were observed in 10 patients (25.6%), of which six (15.4%) had significant PSMs. A persistent detectable prostate-specific antigen level was found in one case after sRP, caused by metastatic disease. One patient had a biochemical recurrence 6 months after sRP. These two cases, together with a PSM case, required additional therapy after sRP. After a median (IQR) follow-up of 17.7 (11.8-26.4) months, urinary continence and erectile function were preserved in 34 (94.4%) and 18 patients (52.9%), respectively, while quality of life remained stable. CONCLUSIONS Salvage RP is safe and feasible for patients with recurrent localised PCa following initial IRE treatment. The medium-term oncological and functional outcomes are similar to primary RP. Strict patient selection for focal therapy and standardised follow-up is needed as some patients developed high-grade disease.

Abstract
Background Video-endoscopic inguinal lymphadenectomy (VEIL) is a minimally invasive approach that is increasingly indicated in oncological settings, with mounting evidence for its long-term oncological safety. Objectives To present our single-center experience of treating penile and urethral cancer with VEIL, as well as its more recent application in melanoma patients. Methods We prospectively recorded our experiences with VEIL from September 2010 to July 2018, registering the patient primary indication, surgical details, complications, and follow-up. Results Twenty-nine patients were operated in one (24) or both (5) groins; 18 had penile cancer, 1 had urethral cancer, and 10 had melanoma. A mean 8.62 ± 4.45 lymph nodes were removed using VEIL and of these, an average of 1.00 ± 2.87 were metastatic; 16 patients developed lymphocele and 10 presented some degree of lymphedema; there were no skin or other major complications. The median follow-up was 19.35 months; there were 3 penile cancer patient recurrences in the VEIL-operated side. None of the melanoma patients presented a lymphatic inguinal recurrence. Conclusions VEIL is a minimally invasive technique which appears to be oncologically safe showing fewer complications than open surgery. However, complications such as lymphorrhea, lymphocele, or lymphedema were not diminished by using VEIL.

Abstract
The quantum perceptron is a fundamental building block for quantum machine learning. This is a multidisciplinary field that incorporates abilities of quantum computing, such as state superposition and entanglement, to classical machine learning schemes. Motivated by the techniques of shortcuts to adiabaticity, we propose a speed-up quantum perceptron where a control field on the perceptron is inversely engineered leading to a rapid nonlinear response with a sigmoid activation function. This results in faster overall perceptron performance compared to quasi-adiabatic protocols, as well as in enhanced robustness against imperfections in the controls.

Abstract
Background One-catheter strategy, based in multipurpose catheters, allows exploring both coronary arteries with a single catheter. This strategy could simplify coronary catheterization and reduce the volume of contrast administration, by reducing radial spasm. To date, observational studies showed greater benefits regarding contrast consumption and catheterization performance than controlled trials. The aim of this work is to perform the first systematic review and meta-analysis of randomized clinical trials (RCT) to adequately quantify the benefits of one-catheter strategy, with multipurpose catheters, over conventional two-catheter strategy on contrast consumption, and catheterization performance. Methods A search in PubMed, CINALH, and CENTRAL databases was conducted to identify randomized trials comparing one-catheter and two-catheter strategies. The primary outcome was volume of iodinated contrast administrated. Secondary endpoints, evaluating coronary catheterization performance included: arterial spasm, fluoroscopy time, and procedural time. Results Five RCT were included for the final analysis, with a total of 1599 patients (802 patients with one-catheter strategy and 797 patients with two-catheter strategy). One-catheter strategy required less administration of radiological contrast (difference in means [DiM] [95% confidence interval (CI)]; -3.831 mL [-6.165 mL to -1.496 mL], p = 0.001) as compared to two-catheter strategy. Furthermore, less radial spasm (odds ratio [95% CI], 0.484 [0.363 to 0.644], p < 0.001) and less procedural time (DiM [95% CI], -72.471 s [-99.694 s to -45.249 s], p < 0.001) were observed in one-catheter strategy. No differences on fluoroscopy time were observed. Conclusions One-catheter strategy induces a minimal reduction on radiological contrast administration but improves coronary catheterization performance by reducing arterial spasm and procedural time as compared to conventional two-catheter strategy.

Abstract
Introduction and objectives The COVID-19 outbreak has had an unclear impact on the treatment and outcomes of patients with ST-segment elevation myocardial infarction (STEMI). The aim of this study was to assess changes in STEMI management during the COVID-19 outbreak. Methods Using a multicenter, nationwide, retrospective, observational registry of consecutive patients who were managed in 75 specific STEMI care centers in Spain, we compared patient and procedural characteristics and in-hospital outcomes in 2 different cohorts with 30-day follow-up according to whether the patients had been treated before or after COVID-19. Results Suspected STEMI patients treated in STEMI networks decreased by 27.6% and patients with confirmed STEMI fell from 1305 to 1009 (22.7%). There were no differences in reperfusion strategy (> 94% treated with primary percutaneous coronary intervention in both cohorts). Patients treated with primary percutaneous coronary intervention during the COVID-19 outbreak had a longer ischemic time (233 [150-375] vs 200 [140-332] minutes, P < .001) but showed no differences in the time from first medical contact to reperfusion. In-hospital mortality was higher during COVID-19 (7.5% vs 5.1%; unadjusted OR, 1.50; 95%CI, 1.07-2.11; P < .001); this association remained after adjustment for confounders (risk-adjusted OR, 1.88; 95%CI, 1.12-3.14; P = .017). In the 2020 cohort, there was a 6.3% incidence of confirmed SARS-CoV-2 infection during hospitalization. Conclusions The number of STEMI patients treated during the current COVID-19 outbreak fell vs the previous year and there was an increase in the median time from symptom onset to reperfusion and a significant 2-fold increase in the rate of in-hospital mortality. No changes in reperfusion strategy were detected, with primary percutaneous coronary intervention performed for the vast majority of patients. The co-existence of STEMI and SARS-CoV-2 infection was relatively infrequent.

Abstract
BACKGROUND Diagnosis of prostate cancer is based on histopathological evaluation, which is time-consuming. Fluorescent confocal microscopy (FCM) is a novel technique that allows rapid tissue analysis. OBJECTIVE To determine if FCM could be used for real-time diagnosis of prostate cancer and evaluate concordance with traditional analysis. DESIGN, SETTING, AND PARTICIPANTS From January 2019 to March 2020, 182 magnetic resonance imaging-targeted prostate biopsy cores from 57 consecutive biopsy-naïve men with suspected prostate cancer were taken. These were intraoperatively stained with acridine orange for analysis using FCM (VivaScope; MAVIG, Munich, Germany) and subsequently sent for traditional haematoxylin-eosin histopathological (HEH) examination. Two expert uropathologists analysed the FCM and HEH cores blinded to the counterpart results in a single institution. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Agreement between FCM and HEH analysis in terms of the presence of cancer was analysed at biopsy core and region of interest (ROI) levels, considering HEH as the reference test. RESULTS AND LIMITATIONS FCM allowed intraoperative assessment of prostate biopsy cores with strong histopathological evaluation agreement: Cohen's κ for agreement was 0.81 at the biopsy core level and 0.69 for the ROI level. Positive predictive values (85% and 83.78%) and negative predictive values (95.1% and 85.71%) were high at the biopsy core and ROI levels. These initial results are encouraging, but given the single-centre and preliminary nature of the study, further confirmation is required. CONCLUSIONS FCM allowed rapid evaluation of prostate biopsy cores. This technique is feasible and achieves rapid closure with a reliable diagnosis, parallel to the gold standard analysis. Initial results are promising but further studies are needed to validate and define the role of this technique. PATIENT SUMMARY A novel microscopic technique reduces the time needed to obtain a prostate cancer diagnosis by speeding up biopsy processing. Although the initial results are promising; this development needs to be confirmed in further studies.

Abstract
BACKGROUND A 2-gene urine-based molecular test that targets messenger RNAs known to be overexpressed in aggressive prostate cancer (PCa) has been described as a helpful method for detecting clinically significant prostate cancer (grade group [GG] ≥2). We performed an external validation of this test in men undergoing initial prostate biopsy (Bx) within a Spanish opportunistic screening scenario. METHODS We analyzed archived samples from 492 men who underwent prostate Bx in an opportunistic screening scenario, with prostate-specific antigen (PSA) 3 to 10 ng/mL and/or suspicious digital rectal exploration (DRE) and without previous multi-parametric magnetic resonance imaging (mpMRI). Urinary biomarker measurements were combined with clinical risk factors to determine a risk score, and accuracy for GG ≥ 2 PCa detection was compared with PCA3, European randomized screening in prostate cancer (ERSPC), and prostate biopsy collaborative group (PBCG) risk calculators in a validation workup that included calibration, discrimination, and clinical utility analysis. RESULTS In our cohort, the detection rates for GG1 and GG ≥ 2 PCa were 20.3% and 14.0%, respectively. The median PSA level was 3.9 ng/mL and 13.4% of subjects had suspicious DRE findings. The median risk score for men with GG ≥ 2 PCa was 21 (interquartile range: 14-28), significantly higher than benign+GG1 PCa (10, 6-18), P < .001, achieving the highest area under the curve among the models tested, 0.749 (95% confidence interval: 0.690-0.807). The urine test was well-calibrated, while ERSPC showed a slight underestimation and PBCG a slight overestimation of risk. Assuming a GG2 non-detection rate of 11% without using mpMRI, use of the urinary biomarker-based clinical model could have helped avoid 37.2% of excess biopsies while delaying the diagnosis of eight patients (1.6% of the entire cohort) with GG ≥ 2 PCa. CONCLUSIONS In this first evaluation in an opportunistic screening population, the urinary biomarker-based test improved the detection of clinically significant PCa. Facing men with elevated PSA and/or suspicious DRE, it could be a useful tool to help avoid excess initial Bx and to identify patients most likely to benefit from Bx.

Abstract
Abstract
Introduction
Left ventricular pseudoaneurysm is a rare mechanical complication of myocardial infarction, and its incidence has decreased with the widespread use of reperfusion therapies. Pseudoaneurysm is the result of a free wall rupture contained by pericardial adherences and mural thrombi, which contain the bleeding and prevent cardiac tamponade.
Clinical Presentation
A 68-year-old woman who had hypertension, diabetes mellitus and chronic kidney disease (caused by diabetic nephropathy) was first admitted with acute myocardial infarction of the inferior wall. Emergent coronary angiography revealed proximal occlusion of the right coronary artery. Primary angioplasty was performed with three stents implantation. However due to transitory no reflow, verapamil, nitrate and intracoronary abciximab were administered with recovery of coronary flow. Patient remained stable, without recurrence of symptoms. Echocardiography, at discharge, showed normal biventricular function and no mechanical complications.
Two months later, the patient was readmitted in the emergency room with constant chest pain, fatigue, prostration and loss of appetite beginning ten days earlier and an episode of syncope. Physical examination revealed fever, cardiac auscultation was rhythmic and without murmurs or pericardial friction rub, and pulmonary auscultation revealed crackles in inferior hemithorax. 12-lead electrocardiogram showed sinus rhythm, Q waves and negative T waves in inferior leads. Blood tests revealed leucocytosis, high sensibility troponin I was 28,8 ng/L and brain natriuretic peptide was 264,9 pg/mL. Chest-X-ray demonstrated enlargement of the cardiac silhouette and echocardiography showed moderate to large pericardial effusion with large amounts of fibrin close to right cardiac chambers and a basal inferior pseudoaneurysm with 23 mm x 24 mm; intracavitary contrast was administered without opacification of pericardial space; biventricular function remained normal.
Patient was promptly admitted on Cardiac Intensive Care Unit with diagnosis of pseudoaneurysm due to myocardial infarction. Therapeutic with ticagrelor was suspended and surgical correction was proposed, after discussion in Heart Team. False aneurysm correction was performed with a bovine pericardial patch without complications, and the patient was discharged asymptomatic eight days later.
Conclusion
Even with lower incidence, pseudoaneurysms remains as a potential life-threatening due to its high risk of rupture. Prompt diagnosis, usually with echocardiography and surgical referral are crucial.

Abstract
Small renal mass incidentally diagnosed are common findings nowadays due to the widespread of imaging. Renal mass biopsy is still underutilized by urologists due to its non-diagnostic rates. Confocal microscopy allows for rapid imaging of fresh tissue samples. We report the feasibility of using confocal technology for determining the quality of the renal core at renal mass biopsy on 4 consecutive cases at our institution.

Abstract
BACKGROUND Coronary angiography with two catheters is the traditional strategy for diagnostic coronary procedures. TIG I catheter permits to cannulate both coronary arteries, avoiding exchanging catheters during coronary angiography by transradial access. OBJECTIVE The aim of this study is to evaluate the impact of one-catheter strategy, by avoiding catheter exchange, on coronary catheterization performance and economic costs. METHODS Transradial coronary diagnostic procedures conducted from January 2013 to June 2017 were collected. One-catheter strategy (TIG I catheter) and two-catheter strategy (left and right Judkins catheters) were compared. The volume of iodinated contrast administered was the primary endpoint. Secondary endpoints included radial spasm, procedural duration (fluoroscopy time) and exposure to ionizing radiation (dose-area product and air kerma). Direct economic costs were also evaluated. For statistical analyses, two-tailed p-values < 0.05 were considered statistically significant. RESULTS From a total of 1,953 procedures in 1,829 patients, 252 procedures were assigned to one-catheter strategy and 1,701 procedures to two-catheter strategy. There were no differences in baseline characteristics between the groups. One-catheter strategy required less iodinated contrast [primary endpoint; (60-105)-mL vs. 92 (64-120)-mL; p < 0.001] than the two-catheter strategy. Also, the one-catheter group presented less radial spasm (5.2% vs. 9.3%, p = 0.022) and shorter fluoroscopy time [3.9 (2.2-8.0)-min vs. 4.8 (2.9-8.3)-min, p = 0.001] and saved costs [149 (140-160)-€/procedure vs. 171 (160-183)-€/procedure; p < 0.001]. No differences in dose-area product and air kerma were detected between the groups. CONCLUSIONS One-catheter strategy, with TIG I catheter, improves coronary catheterization performance and reduces economic costs compared to traditional two-catheter strategy in patients referred for coronary angiography.

Abstract
OBJECTIVES Suburethral male slings are an alternative option for mild stress urinary incontinence. Our purpose is to evaluate the long-term functional outcomes, efficacy and worsening continence of male suburethral slings. MATERIAL AND METHODS The functional outcomes of realignment/anatomical slings were evaluated with AdVance ®, and the outcomes of compressive slings were evaluated with InVance®. We considered 55 patients fulfilling 5 years of complete follow-up. We included patients with a 24-hour pad weight test <400 grams. Night-continent patients who also had positive "repositioning tests" were considered for AdVance®, whereas patients without sphincter contraction or previous pelvic radiotherapy were considered for InVance®. RESULTS Between February 2006 and September 2010, 24 AdVance® and 31 InVance® slings were implanted. The median follow-up times from sling insertion were 75 months in the AdVance® group (range: 64-97) and 86 months in the InVance® group (range: 61-108). At three months of follow-up, 43 of 55 patients were considered to be cured (pad-free) (78.1%), 79.1% in the AdVance® group and 77.4% in the InVance® group. Postoperatively, 16.6% of patients with AdVance® and 22.5% of patients with InVance® presented "de novo" urgency. At 5 years of follow-up, we observed 10 cases of some deterioration of continence, 3 patients in the AdVance® group and 7 in the InVance® group (15.8% and 29.1% of the initially cured, respectively). To date, there have been no reports of urethral sling erosion. CONCLUSIONS Male slings are safe and effective. Although we observed an increase in "de novo" urgency, in our experience, slings seemed to maintain their efficacy during long-term follow-up, and the risks of urethral erosion are low.

Abstract
We develop energy efficient, continuous microwave schemes to couple electron and nuclear spins, using phase or amplitude modulation to bridge their frequency difference. These controls have promising applications in biological systems, where microwave power should be limited, as well as in situations with high Larmor frequencies due to large magnetic fields and nuclear magnetic moments. These include nanoscale NMR where high magnetic fields achieves enhanced thermal nuclear polarization and larger chemical shifts. Our controls are also suitable for quantum information processors and nuclear polarization schemes.

Abstract
OBJECTIVES To analyse the most relevant oncologic results of treatment using radical prostatectomy (RP) for high-risk prostate cancer (HRPC) in a specialist cancer hospital. MATERIAL AND METHODS A descriptive retrospective study of RP was conducted at our centre from 1986 to 2017 on HRPC whose primary objective was to determine overall survival (OS) and cancer-specific survival (CSS). The study's secondary objectives were to determine biochemical progression-free survival (BPFS), metastasis-free survival (MFS), rescue therapy-free survival (RTFS), hormone therapy-free survival (HTFS) and the development of castration-resistant prostate cancer. We performed a Cox regression analysis to establish predictive models and to better understand the weight of each variable that defines high risk. RESULTS A total of 2093 RPs were performed, 480 (22.9%) of which were for HRPC. The median follow-up for the overall series was 79.57 months (P25-75 37.92-135.16). Lymphadenectomy was not performed in 6.5% of the cases. The lymphadenectomy was of the obturator type in 51.2% of the cases and extended in 42.3%. Overall survival at 5, 10 and 15 years was 89.8% (95% CI 86.7-92.9%), 73.3% (95% CI 68-78.6%) and 51.4% (95% CI 43.8-59%), respectively. CSS at 5, 10 and 15 years was 94.8% (95% CI 92.4-97.2%), 84.0% (95% CI 79.3-88.7%) and 75.5% (95% CI 68.8-82.2%), respectively. MFS at 5, 10 and 15 years was 87.4% (95% CI 84.1-90.7%), 72.2% (95% CI 66.7-77.7%) and 61.7% (95% CI 54.3-69.1%), respectively. A total of 120 patients of 477 analysed (25.1%) required rescue radiation therapy, and 293/477 never required hormone therapy (61.4%). Of the 93 pN1 patients, 33 (35.5%) did not require hormone therapy. The time from RP to biochemical progression was the variable with the greatest prognostic weight for MFS, CSS and overall survival. CONCLUSIONS RP plus extended lymphadenectomy should be the first therapeutic manoeuvre when feasible within a multimodal strategy. A longer follow-up of the series is needed to validate the hypothesis of better oncologic results based on the earlier implementation of rescue radiation therapy, extended lymphadenectomy and drugs that prolong survival in the CRPC phase.

Abstract
We propose a quantum control scheme aimed at interacting systems that gives rise to highly selective coupling among their near-to-resonance constituents. Our protocol implements temporal control of the interaction strength, switching it on and off again adiabatically. This soft temporal modulation significantly suppresses off-resonant contributions in the interactions. Among the applications of our method we show that it allows us to perform an efficient rotating-wave approximation in a wide parameter regime, the elimination of side peaks in quantum sensing experiments, and selective high-fidelity entanglement gates on nuclear spins with close frequencies. We apply our theory to nitrogen-vacancy centers in diamond and demonstrate the possibility for the detection of weak electron-nuclear coupling under the presence of strong perturbations.

Abstract
OBJECTIVES PCA3 performance as a single second line biomarker is compared to the European Randomised Study of Screening for Prostate Cancer risk calculator model 3 (ERSPC RC-3) in an opportunistic screening in prostate cancer (PCa). MATERIAL AND METHODS 5,199 men, aged 40-75y, underwent prostate-specific antigen (PSA) screening and digital rectal examination (DRE). Men with a normal DRE and PSA ≥3ng/ml had a PCA3 test done. All men with PCA3 ≥35 underwent an initial biopsy (IBx) -12 cores-. Men with PCA3 <35 were randomized 1:1 to either IBx or observation. We compared them to those obtained with ERSPC RC-3. RESULTS PCA3 test was performed on 838 men (16.1%). In PCA3(+) and PCA3(-) groups, global PCa detection rates were 40.9% and 14.7% with a median follow-up (FU) of 21.7 months (P<.001). In the PCA3(+) arm (n=301, 35.9%), PCa was identified in 115 men at IBx (38.2%). In the randomized arm, 256 underwent IBx and PCa was found in 46 (18.0%) (P<.001). The biopsy-sparing potential would have been 64.1% as opposed to 76.6% if we had used ERSPC RC-3. However, the estimated false negative cases for HGPCa would have been reduced by 37.1% (89 to 56 patients). Moreover, if we had applied PCA3-35 to avoid IBx, 14.7% PCa and 9.1% of clinical significant PCa patients would not have been diagnosed during this FU. CONCLUSIONS When PCA3-35 is used as a second-line biomarker when PSA ≥3ng/ml and DRE is normal, IBx could be avoided in 12.5% less than if ERSPC RC-3 is used and would reduce the false negative cases by 36.2%. At a FU of 21.7 months, this dual protocol would miss 9.1% of clinically significant PCa, so strict FU is mandatory with established biopsy criteria based on PSA and DRE in cases with PCA3 <35.

Abstract
PURPOSE Prognosis of extraskeletal osteosarcoma (ESOS) is reported to be poorer than that of skeletal osteosarcoma. This multicenter retrospective study aimed to evaluate factors influencing ESOS prognosis. PATIENTS AND METHODS Members of the European Musculoskeletal Oncology Society (EMSOS) submitted institutional data on patients with ESOS. RESULTS Data from 274 patients treated from 1981 to 2014 were collected from 16 EMSOS centres; 266 patients were eligible. Fifty (18.7%) had metastases at diagnosis. Of 216 patients with localised disease, 211 (98%) underwent surgery (R0 = 70.6%, R1 = 27%). Five-year overall survival (OS) for all 266 patients was 47% (95% CI 40-54%). Five-year OS for metastatic patients was 27% (95% CI 13-41%). In the analysis restricted to the 211 localised patients who achieved complete remission after surgery 5-year OS was 51.4% (95% CI 44-59%) and 5-year disease-free survival (DFS) was 43% (95% CI 35-51%). One hundred twenty-one patients (57.3%) received adjuvant or neoadjuvant chemotherapy and 80 patients (37.9%) received radiotherapy. A favourable trend was seen for osteosarcoma-type chemotherapy versus soft tissue sarcoma-type (doxorubicin ± ifosfamide) regimens. For the 211 patients in complete remission after surgery, patient age, tumour size, margins and chemotherapy were positive prognostic factors for DFS and OS by univariate analysis. At multivariate analysis, patient age (≤40 years versus >40 years) (P = 0.05), tumour size (P = 0.0001) and receipt of chemotherapy (P = 0.006) were statistically significant prognostic factors for survival. CONCLUSION Patient age and tumour size are factors influencing ESOS prognosis. Higher survival was observed in patients who received perioperative chemotherapy with a trend in favour of multiagent osteosarcoma-type regimen which included doxorubicin, ifosfamide and cisplatin.

Abstract
Congenital pulmonary lymphangiectasia (CPL) and chylothorax (CC) are rare lymphatic developmental disorders. We report six clinical cases of CPL and CC that were admitted to our level III neonatal intensive care unit over the last 20 years. One case of unilateral CC was successfully treated with pleuro-amniotic shunt; three cases of bilateral CC were associated to lung hypoplasia, hydrops fetalis, and generalized lymphangiectasias; one case of CPL was associated with obstructive congenital heart defect; one case of unilateral CC was successfully treated with thoracocentesis and medium-chain triglyceride diet. Mortality was high (66.6%).

Abstract
Selective control of qubits in a quantum register for the purposes of quantum information processing represents a critical challenge for dense spin ensembles in solid-state systems. Here we present a protocol that achieves a complete set of selective electron-nuclear gates and single nuclear rotations in such an ensemble in diamond facilitated by a nearby nitrogen-vacancy (NV) center. The protocol suppresses internuclear interactions as well as unwanted coupling between the NV center and other spins of the ensemble to achieve quantum gate fidelities well exceeding 99%. Notably, our method can be applied to weakly coupled, distant spins representing a scalable procedure that exploits the exceptional properties of nuclear spins in diamond as robust quantum memories.

Abstract
PURPOSE We evaluated the effectiveness of indocyanine green guided pelvic lymph node dissection for the optimal staging of prostate cancer and analyzed whether the technique could replace extended pelvic lymph node dissection. MATERIALS AND METHODS A solution of 25 mg indocyanine green in 5 ml sterile water was transperineally injected. Pelvic lymph node dissection was started with the indocyanine green stained nodes followed by extended pelvic lymph node dissection. Primary outcome measures were sensitivity, specificity, predictive value and likelihood ratio of a negative test of indocyanine green guided pelvic lymph node dissection. RESULTS A total of 84 patients with a median age of 63.55 years and a median prostate specific antigen of 8.48 ng/ml were included in the study. Of these patients 60.7% had intermediate risk disease and 25% had high or very high risk disease. A median of 7 indocyanine green stained nodes per patient was detected (range 2 to 18) with a median of 22 nodes excised during extended pelvic lymph node dissection. Lymph node metastasis was identified in 25 patients, 23 of whom had disease properly classified by indocyanine green guided pelvic lymph node dissection. The most frequent location of indocyanine green stained nodes was the proximal internal iliac artery followed by the fossa of Marcille. The negative predictive value was 96.7% and the likelihood ratio of a negative test was 8%. Overall 1,856 nodes were removed and 603 were stained indocyanine green. Pathological examination revealed 82 metastatic nodes, of which 60% were indocyanine green stained. The negative predictive value was 97.4% but the likelihood ratio of a negative test was 58.5%. CONCLUSIONS Indocyanine green guided pelvic lymph node dissection correctly staged 97% of cases. However, according to our data it cannot replace extended pelvic lymph node dissection. Nevertheless, its high negative predictive value could allow us to avoid extended pelvic lymph node dissection if we had an accurate intraoperative lymph fluorescent analysis.

Abstract
Measuring entanglement is a demanding task that usually requires full tomography of a quantum system, involving a number of observables that grows exponentially with the number of parties. Recently, it was suggested that adding a single ancillary qubit would allow for the efficient measurement of concurrence, and indeed any entanglement monotone associated with antilinear operations. Here, we report on the experimental implementation of such a device-an embedding quantum simulator-in photonics, encoding the entangling dynamics of a bipartite system into a tripartite one. We show that bipartite concurrence can be efficiently extracted from the measurement of merely two observables, instead of 15, without full tomographic information.

Abstract
Background PCA3 has been included in a nomogram outperforming previous clinical models for the prediction of any prostate cancer (PCa) and high grade PCa (HGPCa) at the initial prostate biopsy (IBx). Our objective is to validate such IBx-specific PCA3-based nomogram. We also aim to optimize the use of this nomogram in clinical practice through the definition of risk groups. Methods Independent external validation. Clinical and biopsy data from a contemporary cohort of 401 men with the same inclusion criteria to those used to build up the reference’s nomogram in IBx. The predictive value of the nomogram was assessed by means of calibration curves and discrimination ability through the area under the curve (AUC). Clinical utility of the nomogram was analyzed by choosing thresholds points that minimize the overlapping between probability density functions (PDF) in PCa and no PCa and HGPCa and no HGPCa groups, and net benefit was assessed by decision curves. Results We detect 28 % of PCa and 11 % of HGPCa in IBx, contrasting to the 46 and 20 % at the reference series. Due to this, there is an overestimation of the nomogram probabilities shown in the calibration curve for PCa. The AUC values are 0.736 for PCa (C.I.95 %:0.68–0.79) and 0.786 for HGPCa (C.I.95 %:0.71–0.87) showing an adequate discrimination ability. PDF show differences in the distributions of nomogram probabilities in PCa and not PCa patient groups. A minimization of the overlapping between these curves confirms the threshold probability of harboring PCa >30 % proposed by Hansen is useful to indicate a IBx, but a cut-off > 40 % could be better in series of opportunistic screening like ours. Similar results appear in HGPCa analysis. The decision curve also shows a net benefit of 6.31 % for the threshold probability of 40 %. Conclusions PCA3 is an useful tool to select patients for IBx. Patients with a calculated probability of having PCa over 40 % should be counseled to undergo an IBx if opportunistic screening is required.

Abstract
OBJECTIVE Penile cancer has a predominantly lymphatic dissemination. Lymph nodes metastatic involvement conditions disease prognosis and inguinal lymph node dissection has both prognostic and therapeutic value. High and intermediate risk patients with non-palpable lymph nodes will benefit of a precise diagnosis by means of selective sentinel node biopsy with minimal surgical aggressiveness. METHODS Retrospective review of our experience on dynamic sentinel node biopsy in penile cancer from November 1999 to July 2014. RESULTS We performed this procedure in 33 patients, technically successful in 29 (88%). The patients who did not undergo lymph node dissection due to positive sentinel node biopsy have been followed a mean of 60.4 months (Median 59, range 5-145). 20 patients underwent simultaneous sentinel node biopsy and surgical treatment of the primary lesion and in 13 it was performed posteriorly. In these cases the time lapse was 5.5 months (median 5, range 2-12). In 6 (18.9%) of the 29 patients successfully biopsied, metastasis was founded in any of the lymph nodes identified as sentinel. Two patients were false negative (6,25%). Sensitivity (S), specificity (Sp), positive predictive value (PPV) and negative predictive value (NPV) of successfully performed sentinel node biopsies were 66, 100, 100 and 93%, respectively. CONCLUSION Sentinel node biopsy enables a correct lymph node staging avoiding the morbidity of inguinal lymph node dissection. The rate of technical failure and false negative results is low and it may be considered the diagnostic technique of choice in high and intermediate risk penile cancer with non-palpable lymph nodes.

Abstract
We propose an analog-digital quantum simulation of fermion-fermion scattering mediated by a continuum of bosonic modes within a circuit quantum electrodynamics scenario. This quantum technology naturally provides strong coupling of superconducting qubits with a continuum of electromagnetic modes in an open transmission line. In this way, we propose qubits to efficiently simulate fermionic modes via digital techniques, while we consider the continuum complexity of an open transmission line to simulate the continuum complexity of bosonic modes in quantum field theories. Therefore, we believe that the complexity-simulating-complexity concept should become a leading paradigm in any effort towards scalable quantum simulations.

Abstract
OBJECTIVES To know the necessary information to reproduce the results found in the literature on active surveillance (AS) in prostate cancer (PCa) in our own center so that the information would be objective and correctly given to the patients. We have aimed to study the percentage of candidates for AS chosen in our setting, and the data on infrastaging, subgrading and prediction of insignificant PCa, debugging the predictive value of clinical variables to improve our selection criteria and finally to analyze the results of our patients enrolled in AS. MATERIALS AND METHODS A retro- and prospective review of our data bases was performed. A one-year period was analyzed to know AS candidates. Analysis of our radical prostatectomy specimens for infrastaging, subgrading and prediction of insignificant PCa (Epstein's criteria) was made as well as a uni/multivariate analysis of clinical variables in patients with insignificant PCa in the specimen. A prospective validation was performed with overall survival and survival free of active treatment (SFAT) as endpoints in patients enrolled in AS. RESULTS Between October-2010/October-2011, 44.7% of our PCa were candidates for AS, but only 11.2% choose it. The percentages found for infrastaging, subgrading and prediction of insignificant PCa were 14%, 31.4% and 55.7%, respectively. However, only just 6 patients (6.97%) had≥pT3a+Gleason≥7+volume>0.5cc PCa. The multivariate analysis showed that PSA density and number of affected cores were independent predictors of insignificant PCa. With a mean follow-up of 36±39months, 63 out of 232 patients enrolled in AS went on to active treatment (27.1%), with only 13 due to anxiety without pathologic progression. Median time of SFAT was 72.7 months (CI 95% 30.9-114.4). SFAT at 24 months was 76.4% (69.7-83.1%) and at 48 months 58.1% (48.8-67.4%). Only 10 patients died (4.3%), 9 due to causes different of PCa. Estimated overall survival at 5 years was 92.8% (CI 95% 86.7-98.9%). CONCLUSIONS It should be mandatory to have the exact knowledge of the local data of each Center in order to objectively inform patients about prostate biopsy efficiency, and if percentages of infrastaging, subgrading and prediction of insignificant PCa are in accordance with the literature. At 3 years, we reproduced the results of the longest series of AS, so we have ascertained that our AS protocol can be implemented with increasingly more patients.

Abstract
We propose a method for computing n-time correlation functions of arbitrary spinorial, fermionic, and bosonic operators, consisting of an efficient quantum algorithm that encodes these correlations in an initially added ancillary qubit for probe and control tasks. For spinorial and fermionic systems, the reconstruction of arbitrary n-time correlation functions requires the measurement of two ancilla observables, while for bosonic variables time derivatives of the same observables are needed. Finally, we provide examples applicable to different quantum platforms in the frame of the linear response theory.

Abstract
OBJECTIVES To reduce unnecessary biopsies (Bx) in an opportunistic screening programme of prostate cancer. MATERIAL AND METHODS We perform a prospective evaluation of PCA3 as a second line biomarker in an opportunistic screening for prostate cancer (PCa). From September-2010 until September-2012, 2,366 men, aged 40-74 years and with >10 years life expectancy, were initially screened with PSA/digital rectal examination (DRE). Men with previous Bx or with recent urine infections were excluded. Men with abnormal DRE and/or PSA >3 ng/ml were submitted for PCA3. All men with PCA3 ≥ 35 underwent an initial biopsy (IBx) -12cores-. Men with PCA3 < 35 were randomized 1:1 to either IBx or observation. Re-biopsy(16-18 cores) criteria were PSA increase >.5 ng/ml at 4-6 months or PSAv > .75 ng/ml/year. RESULTS With median follow-up (FU) of 10.1 months, PCA3 was performed in 321/2366 men (13.57%), 289 at first visit and 32 during FU. All 110 PCA3+ men (34.3%) were biopsied and PCa was identified in 43 men in IBx (39.1%). In the randomized arm, 110 were observed and 101 underwent biopsy, finding 12 PCa (11.9%), showing a statistically significant reduction of PCa detection rate in this cohort (P<.001). Global PCa detection rates were 40.9% and 9.5% for the PCA3+ and PCA3- branches, respectively (P<.001). Area under the curve for PSA and PCA3 were .601 and .74, respectively. This is an ongoing prospective study limited by its short follow-up period and still limited enrolment. CONCLUSIONS PCA3 as a second line biomarker within an opportunistic dual screening protocol, can potentially avoid 65.7% and 50.1% biopsies at first round and at median FU of 10.1 months, respectively, just missing around 3.2% of high grade PCa.

Abstract
OBJECTIVE To compare the tumor nature and oncological course of patients operated on by radical prostatectomy in three age groups. MATERIAL AND METHOD From the prospective completion of the data base of our department, we analyzed 1012 patients operated on between 1986 and December 2009. Patients with neo- or adjuvant treatment and those with pre-operative PSA over 50 were excluded. The sample was divided into three groups: younger than 60, 60 to 69 and over 70. The clinical, pathological variables, biochemical course and need for rescue treatment were analyzed. We consider biochemical relapse as when the PSA values reached values greater than 0.4 in two consecutive measurements. Rescue was defined as the need for hormone treatment or radiotherapy. We then made a comparative study, a univariate survival analysis by Kaplan and Meyer Curves and multivariate by Cox's regression. RESULTS The median follow-up was 55.1 months. Of the 1012 patients included in the study, 317 patients (31.3%) had biochemical progression and 259 (25.6%) required rescue treatment. We observed that the groups with the older age had a significantly higher PSA and higher stages than the rest. No differences were observed in the Gleason score of the surgical specimen or in the state of the surgical margins. Biochemical relapse free survival at 5 years was 72.3% (CI 66.4-78.2) in patients under 60 years, 65.3% (CI 60.6-70.0) for patients under 70 and 62.2% (CI 53.2-71.1) for patients of 70 years or older; P<.05. In the univariate study, age was a factor that was significantly associated to biochemical relapse. However, it loses interest in the multivariate study and PSA, pathological state and Gleason score regain interest. Rescue treatment free survival did not differ by age groups. CONCLUSIONS In the current study, worse biochemical evolution of patients over 70 was observed. However, this worse biochemical course was conditioned by clinically more aggressive tumors that, in our opinion, justifies the decision made in regards to the surgical approach taken with these patients.

Abstract
We introduce the concept of embedding quantum simulators, a paradigm allowing the efficient quantum computation of a class of bipartite and multipartite entanglement monotones. It consists in the suitable encoding of a simulated quantum dynamics in the enlarged Hilbert space of an embedding quantum simulator. In this manner, entanglement monotones are conveniently mapped onto physical observables, overcoming the necessity of full tomography and reducing drastically the experimental requirements. Furthermore, this method is directly applicable to pure states and, assisted by classical algorithms, to the mixed-state case. Finally, we expect that the proposed embedding framework paves the way for a general theory of enhanced one-to-one quantum simulators.

Abstract
We propose the implementation of Galileo group symmetry operations or, in general, linear coordinate transformations in a quantum simulator. With an appropriate encoding, unitary gates applied to our quantum system give rise to Galilean boosts or spatial and time parity operations in the simulated dynamics. This framework provides us with a flexible toolbox that enhances the versatility of quantum simulation theory, allowing the direct access to dynamical quantities that would otherwise require full tomography. Furthermore, this method enables the study of noncausal kinematics and phenomena beyond special relativity in a quantum controllable system.
