Abstract
Acute myeloid leukemia is the most common acute leukemia in adults and up to 20% of patients present with hyperleukocytosis at the onset of the disease. The therapeutic approach involves medical support, cytoreductive treatment, and/or leukapheresis. Despite WBC count greater than 100.000/μL, not all patients develop symptoms. To clarify the role of leukapheresis in the setting of hyperleukocytotic AML, we aimed to find associations between AML morphologic subtypes and molecular alterations on presence or absence of leukostasis symptoms (and hence therapeutic vs prophylactic leukapheresis) and clinical outcomes in the cohort of 41 patients at our single center who underwent leukapheresis for hyperleukocytotic AML. There was a trend for increased WBC count, 30-day mortality, M4-M5 AML subtypes, and number of leukapheresis procedures performed in symptomatic hyperleukocytotic pts. No molecular marker was significantly associated with presence or absence of leukostasis symptoms due to small sample size, though there was a trend for increased NPM1-mutated and NPM1 + FLT3-mutated AML in asymptomatic patients and a greater proportion of symptomatic patients who were negative for all assessed molecular alterations. In conclusion, leukapheresis combined with cytoreductive treatment represents a synergic and efficient approach in the management of hyperleukocytosis especially in symptomatic patients considering the higher mortality independently from the presence of specific clonal markers whose distribution among the two groups may result more considerable with a higher number of patients.

Abstract
The detection of individual quanta of light is important for quantum communication, fluorescence lifetime imaging, remote sensing and more. Due to their high detection efficiency, exceptional signal-to-noise ratio and fast recovery times, superconducting-nanowire single-photon detectors (SNSPDs) have become a critical component in these applications. However, the operation of conventional SNSPDs requires costly cryocoolers. Here we report the fabrication of two types of high-temperature superconducting nanowires. We observe linear scaling of the photon count rate on the radiation power at the telecommunications wavelength of 1.5 μm and thereby reveal single-photon operation. SNSPDs made from thin flakes of Bi2Sr2CaCu2O8+δ exhibit a single-photon response up to 25 K, and for SNSPDs from La1.55Sr0.45CuO4/La2CuO4 bilayer films, this response is observed up to 8 K. While the underlying detection mechanism is not fully understood yet, our work expands the family of materials for SNSPD technology beyond the liquid helium temperature limit and suggests that even higher operation temperatures may be reached using other high-temperature superconductors.

Abstract
Abstract
A 45–year old woman presented at the emergency department for palpitations and fever. The EKG, thoracic x–ray and troponins were normal, only a neutrophil leucocytosis was found. The echocardiography showed a normal bi–ventricular and valvular function and a mobile, linear, mass in the left atrium. In order to exclude an infective vegetation the patient underwent to a 2D and 3D transesophageal echocardiography (Figure 1 and 2) which showed a left ventricle concentric remodelling (iLVmass 62 g/m2; RWT 0.45), preserved left and right ventricle function (LVEF according to Simpson 70%; FAC 50%) and valves function; inter–atrial septum defects were excluded, too. The mass was described as a mobile membrane in the left atrium at 2.11 cm from the mitral valve anular plane, which divided the atrium into two separate chambers with a large fenestration without trans–mitralic flow obstruction, supporting a cor triatrium sinister. We excluded endocarditis (the blood cultures were negative, too) and supra–valvular mitral ring (since the left appendage position in the antero–inferior side of the left atrium). The cardiac MRI showed (Figure 3) (SSFP–FIESTA, IR–GRE T1, STIR T2) confirmed the finding of a left atrium divided in two chamber by a iso–intense membraine from the coumadin ridge between the left upper pulmonary vein and the left appendage to the inter–atrial septum fossa ovalis, incomplete in the infero–lateral part. Venous drenaige and other congenital abnormalities were excluded. Miocarditis was excluded since no fibrosis in IR–GRE T1 and no edema in Triple T2 sequences. Since the non–obstructive cor triatrium sinister, grading IA according the Lucas classification, was confirmed, no surgical treatment was proposed and the patient was discharged without complications.

Abstract
Abstract
Aims
Despite the proven benefits of regular physical exercise, and although sportsmen are the paradigm of healthy individuals, the athletes population is not risk-free and can suffer severe clinical conditions including coronary artery disease (CAD) and sudden cardiac death (SCD). Identification of athletes with higher cardiovascular risk is a crucial goal of pre-participation screening.
Methods and results
In this report, we discuss the case of a 79-year-old male. He was a cyclist, who performed a visit to the sports doctor to have issued a certificate for competitive fitness. He was dyslipidaemic, hypertensive, diabetic, and he reported no symptoms. The patient’s ECG revealed an advanced second-degree atrioventricular block. For this reason, he was admitted to the emergency department and he underwent urgent coronary angiography and a temporary Pacemaker. Indeed, a diagnosis of bivasal coronary artery disease was made, and for the first time the patient was subjected to angioplasty of the anterior descending branch and circumflex branch. Subsequently, for the persistence of bradyarrhythmia, he was subjected to a definitive Pacemaker implant.
Conclusions
The benefits of exercise in the overall population are multiple and indisputable, but in athletes with cardiovascular disease exercise can also be associated with adverse clinical events, including SCD. In veterans, a growing group of athletes, CAD is the most common cause of SCD. Detection of subclinical CAD should be the main objective of veteran athlete screening, since the performance of classical cardiovascular risk stratification based on clinical factors appears to be suboptimal.

Abstract
Abstract
Aims
The inflammatory ‘cytokine storm’ that distinguishes COVID-19 pneumonia is associated with a state of systemic hypercoagulability, which leads to thrombotic complications on the venous, arterial, and microvascular side. Indeed, in patients with COVID-19, systemic inflammation, coagulation activation, hypoxemia, and immobilization expose a high risk of pulmonary embolism, which significantly worsens the prognosis of these patients.
Methods and results
In this report, we discuss the case of a 71-year-old female, with no prior medical history, admitted to the emergency department for syncope, dyspnoea, and fever started 48 h earlier. At presentation, ear temperature was 37 °C, oxygen saturation was 96% on oxygen therapy (6 l/min), the patient appeared hypertensive (160/80 mmHg) and tachycardic (114 b.p.m.). Laboratory tests revealed normal white blood cells count (10 000/μl) and increased C reactive protein (5.60 mg/dl), troponin I (0.417 ng/ml), and d-dimer levels (15743 ng/ml). Electrocardiogram showed sinus tachycardia at HR of 120/min, normal atrioventricular conduction time, new onset right bundle branch block, and inverted T waves on DIII. Considering the symptoms, CTPA was performed, revealing massive acute bilateral pulmonary embolism with peripheral ground glass opacities. Those findings were suggestive of COVID-19 pneumonia. Indeed, the patient was positive for SARS-CoV-2 infection, and a diagnosis of COVID-19 pneumonia complicated by pulmonary embolism was made. Treatments included oxygen, subcutaneous low molecular weight heparin (LWMH), and corticosteroids have been administrated according to current international guidelines. Since no haemodynamic instability was observed during hospitalization the patient was discharged on Warfarin therapy for 6 months.
Conclusions
In COVID-19 patients treated in a hospital the incidence of pulmonary embolism (PE) is very high. Patients with COVID-19 infection have respiratory symptoms, which often may not be distinguishable from pulmonary embolism symptoms. So, unexpected respiratory worsening, signs of right ventricular dysfunction on transthoracic echocardiogram, and ECG changes should lead to suspicion of the co-presence of pulmonary embolism. This case report shows how COVID-19 infection can be strongly associated with thrombotic complications. For this reason, the guidelines recommend anticoagulation at standard prophylactic doses in all patients admitted with COVID-19 infection.

Abstract
Abstract
Aims
The Brugada syndrome (Brs) is an inherited disorder associated with risk of ventricular fibrillation and sudden cardiac death in a structurally normal heart. The purpose of this case presentation was to spread awareness about this condition, highlight the importance of timely diagnosis and effective treatment of this channelopathy especially in asymptomatic young athletes at high risk of sudden cardiac death.
Methods and results
In this report, we discuss the case of a 47-year-old male. He was a tennis player who performed a visit to the sports doctor to have issued a certificate for competitive fitness. He had no familiar history of sudden death or syncope. The patient’s electrocardiogram (ECG) revealed J-point elevation and ST-segment elevation in the right precordial leads V1 and V2 positioned in the second, third, or fourth intercostal space, showing classic type II ‘saddleback’ morphology in V2 and BrS was suspected. Hence, the patient underwent Holter ECG monitoring with evidence of spontaneous type 1 Brugada pattern (‘coved’ morphology), as well as frequent ventricular ectopic beats with left branch block morphology. Indeed, a diagnosis of BrS was made. Antiarrhythmic prophylaxis therapy with hydroquinidine was initiated and the patient was suspended from competitive activity with a 3-month follow-up.
Conclusions
The BrS is a hereditary disease characterized by a typical ECG pattern potentially predisposing active individuals with no patent structural heart disease to ventricular arrhythmias (VA) and sudden cardiac death (SCD). Nowadays, it is difficult to discern the true burden of BrS due to the unknown real prevalence of asymptomatic patients and the dynamic variability of the ECG pattern in individuals. The purpose of this case presentation was to spread awareness about this condition, highlight the importance of timely diagnosis, and effective treatment of this channelopathy especially in asymptomatic young athletes at high risk of SCD. Indeed, exercise may potentially worsen the ECG abnormalities in BrS patients, resulting in higher peak J-point amplitudes during the vasovagal reaction of the recovery period, possibly leading to an increased risk of cardiac events. Moreover, the enhanced vagal tone in athletes could be both a BrS risk factor and an exercise effect. For this reason, athletic pre-participation screening is essential for minimizing the risk for SCD in athletes participating in either competitive or leisure sporting activities.

Abstract
The occurrence of chronic myeloid leukemia (CML), or other myeloproliferative diseases, after the development of idiopathic thrombocytopenic purpura (ITP) is very rare in the current medical literature. Considering the advances in ITP management, and the wide use of new drugs for ITP and CML, we report an unusual case with this association. Our case report focused on a 64-year-old man with long-standing ITP treated with eltrombopag, who developed hyperleukocytosis during follow-up; after specific laboratory exams, it was diagnosed as CML and he began treatment with imatinib. The treatment with eltrombopag was balanced with imatinib to stabilize his platelet count. Data on bcr-abl and JAK2 transcripts were collected and revealed an optimal response with the achievement of negativization of both molecular signatures. We could demonstrate that treatment with imatinib and eltrombopag was well tolerated and allowed complete molecular remission of CML to be achieved, as well as of ITP.

Abstract
We developed superconducting nanowire single-photon detectors based on tungsten silicide, which show saturated internal detection efficiency up to a wavelength of 10 μm. These detectors are promising for applications in the mid-infrared requiring sub-nanosecond timing, ultra-high gain stability, low dark counts, and high efficiency, such as chemical sensing, LIDAR, dark matter searches, and exoplanet spectroscopy.

Abstract
As the limits of traditional von Neumann computing come into view, the brain's ability to communicate vast quantities of information using low-power spikes has become an increasing source of inspiration for alternative architectures. Key to the success of these largescale neural networks is a power-efficient spiking element that is scalable and easily interfaced with traditional control electronics. In this work, we present a spiking element fabricated from superconducting nanowires that has pulse energies on the order of ∼10 aJ. We demonstrate that the device reproduces essential characteristics of biological neurons, such as a refractory period and a firing threshold. Through simulations using experimentally measured device parameters, we show how nanowire-based networks may be used for inference in image recognition and that the probabilistic nature of nanowire switching may be exploited for modeling biological processes and for applications that rely on stochasticity.

Abstract
Electromagnetic fields (EMFs) have been proposed as a tool to ameliorate bone formation and healing. Despite their promising results, however, they have failed to enter routine clinical protocols to treat bone conditions where higher bone mass has to be achieved. This is no doubt also due to a fundamental lack of knowledge and understanding on their effects and the optimal settings for attaining the desired therapeutic effects. This review analysed the available in vitro and in vivo studies that assessed the effects of sinusoidal EMFs (SEMFs) on bone and bone cells, comparing the results and investigating possible mechanisms of action by which SEMFs interact with tissues and cells. The effects of SEMFs on bone have not been as thoroughly investigated as pulsed EMFs; however, abundant evidence shows that SEMFs affect the proliferation and differentiation of osteoblastic cells, acting on multiple cellular mechanisms. SEMFs have also proven to increase bone mass in rodents under normal conditions and in osteoporotic animals.

Abstract
The basis for superconducting electronics can broadly be divided between two technologies: the Josephson junction and the superconducting nanowire. While the Josephson junction (JJ) remains the dominant technology due to its high speed and low power dissipation, recently proposed nanowire devices offer improvements such as gain, high fanout, and compatibility with CMOS circuits. Despite these benefits, nanowire-based electronics have largely been limited to binary operations, with devices switching between the superconducting state and a high-impedance resistive state dominated by uncontrolled hotspot dynamics. Unlike the JJ, they cannot increment an output through successive switching and their operation speeds are limited by their slow thermal-reset times. Thus, there is a need for an intermediate device with the interfacing capabilities of a nanowire but a faster, moderated response allowing for modulation of the output. We present a nanowire device based on controlled fluxon transport. We show that the device is capable of responding proportionally to the strength of its input, unlike other nanowire technologies. The device can be operated to produce a multilevel output with distinguishable states, the number of which can be tuned by circuit parameters. Agreement between experimental results and electrothermal circuit simulations demonstrates that the device is classical and may be readily engineered for applications including use as a multilevel memory.

Abstract
Renal angiomyolipoma (AML) is a benign mesenchymal tumour. AML often leads to haemorrhagic complications such as retroperitoneal haematoma. Treatment varies from case to case, ranging from minimally invasive approaches such as selective embolization of the renal artery to invasive wedge resection, partial nephrectomy or, in more severe cases, radical nephrectomy. Here we report a case of retroperitoneal haematoma secondary to AML, treated with conservative approach by super-selective embolization of the lower-pole segmental renal artery.

Abstract
Neoadjuvant chemotherapy (NACT) in locally advanced breast tumors may allow an adequate control of the disease impossible with surgery alone. Moreover, NACT increases the chance of breast-conserving surgery. Between 2008 and 2012, we treated with NACT 83 patients with locally advanced breast cancer. We report the preliminary results evaluating the impact of NACT on the type of surgery.

Abstract
INTRODUCTION Inflammatory myofibroblastic tumor (IMT) is a benign solid tumor of uncertain etiology. MATERIALS AND METHODS We report a case of a 4-year-old Down syndrome affected child, who had a pancreatic mass identified by ultrasonography (US) and confirmed by computed tomography (CT). RESULTS Monitoring of IMT was performed by serial US studies, and at follow-up after 4 years there was no relapse. DISCUSSION As radical removal of the lesion was not possible, the patient was successfully treated with nonsteroidal anti-inflammatory drugs (NSAIDs). It was decided to monitor the lesion by serial US in order to reduce the number of CT examinations and thereby avoid excessive exposure to ionizing radiation. It is widely reported in the literature that repeated CT scans are associated with increased exposure to radiation which may cause cancer, a fact which should not be overlooked in children.

Abstract
A large proportion of patients hospitalised for severe neuromotor disorders are supported during the in-hospital rehabilitation program by family members. To target interventions of psychological support for these caregivers it can be of help to identify the causes of caregiver burden or specific needs. Anxiety and depression are common in caregivers and constitute, together with emotional distress caused by loneliness and reduced social activities, an important part of the caregiving burden. This paper presents results emerging from a clinical intervention of psychological support offered to caregivers of neuromotor patients, mainly post-stroke, who were undergoing a course of in-hospital rehabilitation. A psychometric assessment was carried out on a sample of 50 caregivers, spouses or children, at the beginning and end of the in-hospital rehabilitation period. The following questionnaires were used: the Revised Anxiety and Depression Scale (RADS), measuring anxiety and depression, the Caregiver Need Assessment (CNA), assessing needs related to the assisted patient, and the Family Strain Questionnaire (FSQ) for a broader assessment of the problems faced by caregivers. The Functional Independence Measure (FIM) was completed by the medical doctor. A significant reduction was found, between the beginning and end of the rehabilitation period, in the needs related to patient care on the CNA (p < 0.001). Caregiver females, in contrast to males, showed an improvement in mood compared to the beginning of the rehabilitation period (p < 0.05). About half of the sample had, at the beginning, a marked clinical level of anxiety while 22% of caregivers had a marked clinical level of depression. Caregivers who received intense psychological support, i.e. at least one interview with the psychologist per week, showed, in contrast to those who received 3-4 interviews during the entire rehabilitation period, a decline in thoughts of death (p < 0.05) and, in cases where baseline anxiety was above the clinical cut-off, a reduced level of anxiety (p < 0.05). At the beginning of rehabilitation, there emerged: higher anxiety scores in caregivers who live with their patient (p < 0.05) compared to those living alone or with others; an increase in depression scores in inverse proportion to the patient's age (p = 0.01); higher scores of emotional stress in spouses (p < 0.05) compared to children and in caregivers of patients with left hemisphere deficits (p < 0.05); a greater need for knowledge about the disease (p < 0.001) and more thoughts of death (p < 0.05) in caregivers of female patients. These characteristics may be considered "alarm signals" that should alert hospital medical staff to the need to seek psychological help for the caregiver. At the end of rehabilitation, a greater degree of psychological strain was observed in caregivers of patients with severe disability. High needs related to the assisted patient (p < 0.01), high scores of emotional stress (p < 0.05), problems of social involvement (p < 0.05) and thoughts of death about the patient (p < 0.05) were found in caregivers of patients who had persisting high motor disability or who were admitted for consequences of a left hemisphere lesion. High depression scores were also found in caregivers of patients with high residual cognitive disability (p < 0.05). This psychometric evaluation makes it possible to tailor the psychological support offered to the needs of each individual caregiver both during rehabilitation and in relation to eventual future developments. A multidisciplinary team approach to the caregiver can thus lead to a general reduction of caregiver strain.

Abstract
BACKGROUND A prospective phase II study was conducted to evaluate the efficacy and toxicity of the combination docetaxel (Taxotere) (DTX) and oxaliplatin (OXA) in ovarian cancer patients recurring after a platinum-free interval (PFI) >12 months. PATIENTS AND METHODS DTX, 75 mg/m(2), was administered by 60 min i.v. infusion, followed by OXA, 100 mg/m(2), given by a 2 h i.v., on day 1 every 21 days. RESULTS From October 2003 to June 2006, 43 ovarian cancer patients were enrolled. Median PFI was 26 months. All patients were available for response evaluation: 17 complete responses and 12 partial responses were registered, for an overall response rate of 67.4%. The median response duration was 10 months. Stable disease was documented in 11 patients (median duration = 5.5 months). The median time to progression and overall survival were 14 and 28 months. A total of 259 courses were administered. Grade 3-4 leukopenia was documented in 32.5% of the patients, while no case of severe anemia and thrombocytopenia was observed. Grade 3-4 neurotoxicity and grade 2 alopecia were observed in 9.3% and 34.9% of cases, respectively. CONCLUSION DTX/OXA combination is an active regimen with a favorable toxicity profile, for treatment of recurrent platinum-sensitive ovarian cancer patients.

Abstract
15009 Background: Cyclooxygenase-2 (COX-2) has been shown to be involved in several steps of ovarian onset and progression and its overepression is associated with a poor chance of response to chemotherapy and poor prognosis in ovarian cancer. Celecoxib, an orally active selective COX-2 inhibitor, has been tested for its ability to potentiate the activity of carboplatin in treatment of heavily pretreated recurrent ovarian cancer patients. Methods: A phase II study was planned, considering the regimen active if at least 12 responses were observed among the 43 enrolled patients. Celecoxib (400 mg/die), and carboplatin (5 AUC) q28 were administered, until progression or unacceptable toxicity. Response was assessed by RECIST and also by Rustin criteria. Results: 34 pts (median age: 60 yrs, range 28–74) and an ECOG performance status (0/1/2) of (21/12/1), were enrolled. 58.8% of patients were platinum resistant (progressing during or < 6 months from primary treatment). Median number of previous chemotherapy regimens was 3 (range 2–6). Currently 27 patients are evaluable for response. The overall response rate (CR and PR) was 25.9% (2 CR, 5 PR) with stabilization of disease in 8 patients (29.6%). Four responses occurred in platinum sensitive and 3 in platinum resistant group Median time to response was 11 weeks (range 9–19) and median duration of response was 23 weeks (range 12–39). According to Rustin criteria 10 patients out of 25 (40%) were considered responsive to treatment (return of CA125 levels to normal level or >50% reduction). Overall, 143 cycles were administered with a median value of 3 cycles (range = 1–10). Moderate/severe toxicities were as follows: G3 anemia occurred in 2.3% cycles, G3 neutropenia in 4.6% cycles, G3 thrombocytopenia in 1.5% cycles, G3/4 gastrointestinal toxicity occurred in 4.6% cycles. Cutaneous diffuse erithema was observed in 2 patients, in both cases recovered with a short period of antihistaminic treatment; 2 cases of hypertension were documented, G2 hypersensitivity reactions during carboplatin infusion were observed in 4 cases. Conclusions: Celecoxib combined with carboplatin is well tolerated and has promising activity as salvage treatment in heavily pretreated recurrent ovarian cancer patients. No significant financial relationships to disclose.

Abstract
Two studies were conducted that assessed health perceptions and functional health status among an urban, low-income population in the southeastern region of the United States. The first study was conducted with 176 hospitalized indigent patients prior to discharge from a county hospital. Patients were administered the Short Form-36 (SF-36) health status questionnaire and two additional questions regarding perceptions of health. The second study was conducted in the same geographic region with a nonhospitalized, low-income population. The SF-36 was administered by telephone to 546 randomly selected interview respondents. The results demonstrated consistent differences between black and white respondents in referents for self-perceived health. It is suggested that health expectations and perceptions may be indicative of the cultural, contextual, and social-political factors that affect the lives of this urban, low income population. The validity of global single-item health indicators for use among low-income populations is questioned. Further research is needed to develop patient-based measures that accurately reflect the meanings and values of low-income patient groups.

Abstract
The criteria by which the operative approaches to craniopharyngioma are chosen are still controversial. The authors performed a retrospective analysis in 32 patients with craniopharyngioma who were surgically treated. Results of neurological and psychological tests administered during the follow-up period were correlated with the surgical approach. On the basis of these preliminary data and a maximum follow-up period of 10 years, the authors conclude that the subfrontal approach to the craniopharyngioma and partial removal of its solid part appears to be associated with a lower morbidity rate and minor frontal lobe disorders.

Abstract
In order to characterize neurological, intellectual and behavioral sequelae better after surgical treatment of brain abscess in childhood, 32 children were studied over a 10-year time span after treatment of a brain abscess. Depending on the clinical condition, surgical treatment consisted of simple aspiration through a burr hole or of total excision after craniotomy. There were only 3 postoperative deaths (9%). The scheduled time for long-term follow-up was 3 years after surgery. The patient assessment included information concerning the presence of seizures, accurate neurological examination, an EEG, and a battery of intellectual tests to evaluate the presence of behavioral-mental deficits. Late seizures developed in 7 of the 29 survivors. Five patients presented permanent hemiparesis after surgical treatment. It is noteworthy that the intellectual impairment observed was more severe in younger patients, while the behavioral disturbances were more marked in school-age children.
