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
BACKGROUND AND AIM Pulmonary regurgitation is the most common complication in repaired tetralogy of Fallot patients. Severe chronic pulmonary regurgitation can be tolerated for decades, but if not treated, it can progress to symptomatic, irreversible right ventricular dilatation and dysfunction. We investigated clinical associations with pulmonary valve replacement among patients with significative pulmonary regurgitation and how interventional developments can change their management. METHODS All adult patients with repaired tetralogy of Fallot who were followed at an adult CHD Clinic at a single centre from 1980 to 2022 were included on their first outpatient visit. Follow-up was estimated from the time of correction surgery until one of the following events occurred first: pulmonary valve replacement, death, loss to follow-up or conclusion of the study. RESULTS We included 221 patients (116 males) with a median age of 19 (18-25). At a median age of 33 (10) years old, 114 (51%) patients presented significant pulmonary regurgitation. Among patients with significant pulmonary regurgitation, pulmonary valve replacement was associated with male gender, older age at surgical repair, and longer QRS duration in adulthood. Pulmonary valve replacement was performed in 50 patients, including four transcatheter pulmonary valve implantations, at a median age of 34 (14) years. CONCLUSION Pulmonary regurgitation affects a large percentage of tetralogy of Fallot adult patients, requiring a long-term clinical and imaging follow-up. Sex, age at surgical repair and longer QRS are associated with the need of PVR among patients with significative pulmonary regurgitation. Clinical practice and current literature support TPVI as the future gold standard intervention.

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
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
BACKGROUND Chylothorax in neonates results from leakage of lymph from thoracic lymphatic ducts and is mainly congenital or posttraumatic. The clinical course of the effusion is heterogeneous, and consensus on treatment, timing, and modalities of measures has not yet been established. This review aims to present, along with levels of evidence and recommendation grades, all current therapeutic possibilities for the treatment of chylothorax in neonates. METHODS An extensive search of publications between 1970 and 2020 was performed in the PubMed, Cochrane Database of Systematic Reviews, and UpToDate databases. A stepwise approach algorithm was proposed for both congenital and traumatic conditions to guide the clinician in a rational and systematic way for approaching the treatment of neonates with chylothorax. DISCUSSION AND CONCLUSION The treatment strategy for neonatal chylothorax generally involves supportive care and includes drainage and procedures to reduce chyle flow. A stepwise approach starting with the least invasive method is advocated. Progression in the invasiveness of treatment options is determined by the response to previous treatments. A practical stepwise approach algorithm is proposed for both, congenital and traumatic chylothoraces.

Abstract
INTRODUCTION AND OBJECTIVES COVID-19 pandemic forced a change in health care resources and provision due to the emergence of a new group of patients, requiring extraordinary protective measures and the adoption of new organization for the treatment of urgent or priority COVID-19 negative patients. We reviewed our practice during the first pandemic period to evaluate our surgical outcomes and identify if patients COVID-19 negative submitted to thoracic surgery had an increased risk of being infected or die. METHODS We retrospectively reviewed our surgical results between 11th March and 15th May 2020. Thirty patients underwent thoracic surgery at the Department of Cardiothoracic Surgery of Centro Hospitalar Universitário de São João. RESULTS None of the patients was COVID-19 positive and cross-transmission of the disease was not recognized. The majority of patients were admitted from home, with a high priority indication, namely an oncological disease. There was only one case of in-hospital mortality. CONCLUSION During the first wave of the pandemic it was safe to be admitted and submitted to thoracic surgery at CHUSJ. Our patients, including oncological patients, received the adequate surgical treatment without an increase of risk of death or infection.

Abstract
OBJECTIVES Our objective was to examine the results of ECMO post cardiotomy in Centro Hospitalar Universitário S. João (CHUSJ). METHODS Between 2011 and 2019, 13 patients were cannulated for refractory cardiogenic shock post-cardiotomy; 8 (61,5%) male and 5 (38,5%) female. Patients under 18 years old were excluded. Data was collected from hospital archives concerning preoperative comorbidities, open-heart surgery procedure, dates of ECMO cannulation and decannulation, postoperative complications, hospital mortality and cause of death. Follow-up was obtained by review of the last outpatient observation. The outcomes investigated were hospital mortality and survival at 12, 36 and 60 months. RESULTS After a median ECMO-VA therapy of 6 days (1-16 days), 7 (53,8%) patients were successfully decannulated; from these 2 succumbed from stroke and septic shock, one is still in intermediate care convalescing steadily and 4 were discharged. Overall 8 (61,5%) patients died. 5 (38,5%) survived, 4 were discharged home and 1 is still in intermediate care. Survival (after discharge) at 12, 36 and 60 months was respectively 25%, 16,7% and 8,3%. Regarding postoperative complications, reoperation for bleeding was necessary in 5 (38.5%), stroke was diagnosed in 2 (15,4%), dialysis in 6 (46,2%), leg ischemia affected 5 (38,5%) and mediastinitis occurred in 1 (7,7%). CONCLUSIONS VA ECMO saves a life in each three patients suffering from refractory cardiogenic shock after cardiac surgery. Despite risks associated with advanced cardiopulmonary support, survivors maintain good health condition.

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 Covid‐19 was declared a pandemic by the World Health Organization (WHO) on 11 March 2020. Responses to this crisis integrated resource allocation for the increased amount of infected patients while maintaining an adequate response to other severe and life‐threatening diseases. Though cardiothoracic patients are at high risk for Covid‐19 severe illness, postponing surgeries would translate to increased mortality and morbidity. We reviewed our practice during the initial time of the pandemic, with emphasis on safety protocols. Methods From 11 March to 15 May 2020, 148 patients underwent surgery at the Department of Cardiothoracic Surgery of Centro Hospitalar Universitário de São João. The clinical characteristics of the patients were retrospectively registered, along with novel containment and infection prevention measures targeting the new coronavirus. Results The majority of adult cardiac patients were operated on an emergency basis. Hospital mortality was 1.9% (n = 2 patients). Most adult thoracic patients were admitted from home, with a diagnosis of neoplastic disease in 60% of patients. Hospital mortality was 3.3% (1 patient). Fifteen children underwent cardiothoracic surgery. There was no mortality. The infection prevention procedures applied, totally excluded the transmission of Covid‐19 in the department. Conclusion While guaranteeing a prompt response to emergent, urgent, and high priority cases, novel safety measures in individual protection, patients circuits, and preoperative diagnoses of symptomatic and asymptomatic infection were adopted. The surgical results corroborate that it was safe to undergo cardiothoracic surgery during the initial time of the Covid‐19 pandemic. The new policies will be maintained while the virus stays in the community.

Abstract
We present a rare case of a levoatrial cardinal vein identified during the work-up of a patient with coarctation of the aorta. Early diagnosis and repair in the neonatal period prevented future manifestations of left-to-right shunt and the need for reoperations, in contrast with the later-age presentation of this congenital anomaly. An integrative approach was crucial for prompt detection, intraoperative confirmation and complete one-stage repair.

Abstract
BACKGROUND Vena cava anomalies are rare congenital defects due to incorrect development during fetal life, ranging from minor asymptomatic anatomic variations to complex life-threatening abnormalities. Echocardiography plays a fundamental role in the diagnosis, with advanced imaging techniques allowing detailed anatomic delineation. Invasive cardiology techniques are a promising therapeutic approach, but surgery is probably the best option when diffuse compromise of the systemic veins is present. CASE REPORT An 8-month-old infant presenting episodes of labial cyanosis and a failure to thrive was diagnosed with severe superior vena cava (SVC) stenosis at the right atrium ostium, with decompression via azygos vein and mild inferior vena cava (IVC) stenosis. The patient was referred for surgery, with IVC enlargement and removal of a fibromuscular tissue band on the anterior aspect of the SVC ostium. At a 6-month follow-up, the patient is asymptomatic, with excellent surgical outcome. To the authors' knowledge, only two cases of congenital SVC stenosis have been previously described.

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
Lung herniation is an uncommon entity which was fully classified in 1845 after the study of several case reports. Acquired lung hernia, especially traumatic, is the most common etiology. In the absence of clear guidelines, management of lung hernia is made in a case-by-case basis. We present an asymptomatic middle lobe hernia perceptible on physical examination, but diagnosed initially by imaging studies. Patient medical history included a blunt bull trauma fourteen years before.

Abstract
We develop theoretically and demonstrate experimentally a universal dynamical decoupling method for robust quantum sensing with unambiguous signal identification. Our method uses randomization of control pulses to simultaneously suppress two types of errors in the measured spectra that would otherwise lead to false signal identification. These are spurious responses due to finite-width π pulses, as well as signal distortion caused by π pulse imperfections. For the cases of nanoscale nuclear-spin sensing and ac magnetometry, we benchmark the performance of the protocol with a single nitrogen vacancy center in diamond against widely used nonrandomized pulse sequences. Our method is general and can be combined with existing multipulse quantum sensing sequences to enhance their performance.

Abstract
Pulmonary sequestration (PS) is a rare congenital malformation, even more when its arterial supply is a coronary artery. We present a case of a 68-year-old man admitted in the emergency room with an acute coronary syndrome and no evidence of significant coronary disease. Instead, he had an abnormal branch from the circumflex coronary artery nourishing a mass in the left lower pulmonary lobe. A coronary steal phenomenon was proposed to explain the clinical presentation. An anterior left thoracotomy with ligation of the abnormal branch and atypical resection of the lung segment comprising the sequestration was performed.

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
Quantum field theories describe a variety of fundamental phenomena in physics. However, their study often involves cumbersome numerical simulations. Quantum simulators, on the other hand, may outperform classical computational capacities due to their potential scalability. Here we report an experimental realization of a quantum simulation of fermion-antifermion scattering mediated by bosonic modes, using a multilevel trapped ion, which is a simplified model of fermion scattering in both perturbative and non-perturbative quantum electrodynamics. The simulated model exhibits prototypical features in quantum field theory including particle pair creation and annihilation, as well as self-energy interactions. These are experimentally observed by manipulating four internal levels of a 171Yb+ trapped ion, where we encode the fermionic modes, and two motional degrees of freedom that simulate the bosonic modes. Our experiment establishes an avenue towards the efficient implementation of field modes, which may prove useful in studies of quantum field theories including non-perturbative regimes.

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
We demonstrate that the quantum phase transition (QPT) of the Rabi model and critical dynamics near the QPT can be probed in the setup of a single trapped ion. We first demonstrate that there exists equilibrium and nonequilibrium scaling functions of the Rabi model by finding a proper rescaling of the system parameters and observables, and show that those scaling functions are representative of the universality class to which the Rabi model belongs. We then propose a scheme that can faithfully realize the Rabi model in the limit of a large ratio of the effective atomic transition frequency to the oscillator frequency using a single trapped ion and, therefore, the QPT. It is demonstrated that the predicted universal functions can indeed be observed based on our scheme. Finally, the effects of realistic noise sources on probing the universal functions in experiments are examined.

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
Fungal prosthetic valve endocarditis is an extremely severe form of infective endocarditis, with poor prognosis and high mortality despite treatment. Candida albicans is the most common etiological agent for this rare but increasingly frequent condition. We present a case of fungal prosthetic valve endocarditis due to C. albicans following aortic and pulmonary valve replacement in a 38-year-old woman with a history of surgically corrected tetralogy of Fallot, prior infective endocarditis and acute renal failure with need for catheter-based hemodialysis. Antifungal therapy with liposomal amphotericin B was initiated prior to cardiac surgery, in which the bioprostheses were replaced by homografts, providing greater resistance to recurrent infection. During hospitalization, a mycotic aneurysm was diagnosed following an episode of acute arterial ischemia, requiring two vascular surgical interventions. Despite the complications, the patient's outcome was good and she was discharged on suppressive antifungal therapy with oral fluconazole for at least a year. The reported case illustrates multiple risk factors for fungal endocarditis, as well as complications and predictors of poor prognosis, demonstrating its complexity.

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.
