RESUMO

To gain a deeper understanding of consumers' brain responses during a real-time in-store exploration could help retailers to get much closer to costumers' experience. To our knowledge, this is the first time the specific role of touch has been investigated by means of a neuroscientific approach during consumer in-store experience within the field of sensory marketing. This study explores the presence of distinct cortical brain oscillations in consumers' brain while navigating a store that provides a high level of sensory arousal and being allowed or not to touch products. A 16-channel wireless electroencephalogram (EEG) was applied to 23 healthy participants (mean age = 24.57 years, SD = 3.54), with interest in cosmetics but naive about the store explored. Subjects were assigned to two experimental conditions based on the chance of touching or not touching the products. Cortical oscillations were explored by means of power spectral analysis of the following frequency bands: delta, theta, alpha, and beta. Results highlighted the presence of delta, theta, and beta bands within the frontal brain regions during both sensory conditions. The absence of touch was experienced as a lack of perception that needs cognitive control, as reflected by Delta and Theta band left activation, whereas a right increase of Beta band for touch condition was associated with sustained awareness on the sensory experience. Overall, EEG cortical oscillations' functional meaning could help highlight the neurophysiological implicit responses to tactile conditions and the importance of touch integration in consumers' experience.

RESUMO

BACKGROUND: Little is known about the coronavirus SARS-CoV-2 disease (COVID-19) in solid organ transplanted patients. We here report a series of heart transplanted patients with COVID-19 from two centers of Italy. METHODS: All heart transplanted patients of Transplant Centers of Bergamo and Torino with a microbiologically confirmed SARS-CoV-2 infection were enrolled. Data collection included clinical presentation, laboratory and radiological findings, treatment and outcome. Follow-up was performed by visit or phone. RESULTS: From February to March 2020 twenty-six heart transplanted patients (age 62±12 years; 77% males; time from transplant 10±10 years; 69% with comorbidities) had a microbiologically confirmed COVID-19. The most frequent symptom was fever, followed by cough. Seventeen patients had a pneumonia, 8 of them severe pneumonia. Seven patients died (27%) and 17 (65%) were hospitalized. Discontinuation of immunosuppression was associated with death (71 vs 21%, p=0.02). Conversely, all patients receiving steroids survived (p<0.001). Patients who received heart transplantation during COVID-19 outbreak survived and no acute graft rejection occurred. Patients who died were older than survivors, had a longer time from transplant and a worse clinical presentation at diagnosis. The current regimen enabled the prolonged survival and function of orthotopic cardiac xenografts in altogether 6 of 8 baboons, of which 4 were now added. These results exceed the threshold set by the Advisory Board of the International Society for Heart and Lung Transplantation. CONCLUSIONS: COVID-19 has a significant impact on long term heart transplanted patients. Conversely, SARS-CoV-2 infection seems to have a limited influence on more recent transplants. Our experience may suggest that heart transplantation programs can be maintained even during the pandemic phase if specific and tailored paths to prevent and to limit virus transmission are provided.

RESUMO

OBJECTIVES: Heart transplantation (HTx) in children with a univentricular physiology is a challenge. In this study, we aimed to investigate the early and late survival as well as the causes of death of HTx recipients at different stages of univentricular palliation. METHODS: Between January 1987 and September 2015, 40 orthotropic cardiac transplants were performed in 38 children with univentricular hearts at our institution. Outcomes were reviewed using medical records and transplant databases. RESULTS: For the purposes of this analysis, patients were divided into 3 subgroups according to their stage of palliation: Stage 1 (n = 10, 26%), Stage 2 (n = 5, 13%) and Fontan (n = 23, 61%). The median age at HTx was 15.2 years (range 0-38). The median follow-up time after transplantation was 8.7 years (range 0-25.4). Indications for transplant were ventricular dysfunction in 25 (66%) patients, protein losing enteropathy in 10 patients transplanted in Fontan (26%) and refractory arrhythmias in 3 (8%) patients with an atriopulmonary connection. Total mortality was 42% (4.84/100 patient-years), and total early mortality was 21%. Overall survival at 1, 10 and 20 years was 73% (95% confidence interval 56-84%), 58% (95% confidence interval 40-72%) and 49% (95% confidence interval 30-65%), respectively. CONCLUSIONS: HTx is a feasible option for patients with failing univentricular circulation, and although the mortality rate is high, this rate is still comparable to that in patients undergoing HTx for other congenital and non-congenital heart diseases.

RESUMO

BACKGROUND: Optimal management of posttransplant lymphoproliferative disease (PTLD) remains to be defined due to heterogeneity of this condition and lack of predictors of the outcome. Here we report our experience with pediatric PTLD nonresponsive to immunosuppression (IS) withdrawal, managed after stratification into high and low risk according to the presenting features. METHODS: This is a single-center retrospective review of prospectively enrolled patients. From 2001 to 2011, 17 children were diagnosed with severe B-lineage, CD20+, PTLD after a median of 37 months (range, 5-93) from liver (12), heart (4), or multiorgan (1) transplantation. Treatment was tailored on 2 risk groups: (1) standard-risk (SR) patients received IS reduction and rituximab; (2) high-risk (HR) patients received IS discontinuation, rituximab and polychemotherapy. RESULTS: The cumulative incidence of rejection at 1 and 5 years after the diagnosis of PTLD was 35% (95% confidence interval [95% CI], 18-69%) and 53% (33-85%), respectively, whereas the disease-free survival at 1 and 5 years was 94% (95% CI, 65-99%) and 75% (45-90%), respectively. Three children died, PTLD-free, from different transplant-related complications: primary nonfunction after retransplantation (liver), cytomegalovirus disease 21 months after PTLD treatment (liver), graft dysfunction 25 months after PTLD (heart). CONCLUSIONS: Severe B-lineage PTLD after solid organ transplantation may be classified as SR or HR and treated accordingly with a tailored protocol obtaining a satisfactory long-term outcome. This approach accomplishes the control of lymphoproliferation in severe forms as well as the minimization of toxicity in milder PTLDs.

RESUMO

CHL type is the least common major form of EBV-related PTLD but rarely occurs in pediatric recipients; development of CHL subsequent to other PTLD subtypes in the same transplant recipient is even more unusual. Because of its rarity, indications on the best treatment strategy are limited. Patients have been mostly treated with standard HL chemotherapy/radiotherapy, and prognosis seems more favorable than other monomorphic PTLDs. Herein, we describe a pediatric case of EBV-associated, stage IV-B, CHL arising in a heart allograft recipient eight yr after diagnosis of B-cell polymorphic PTLD. The patient was successfully treated with adjusted-dose HL chemotherapy and autologous EBV-specific CTL, without discontinuation of maintenance immunosuppression. At two yr from therapy completion, the patient is in CR with stable organ function. With this strategy, it may be possible to reproduce the good prognostic data reported for CHL-type PTLD, with decreased risk of organ toxicity or rejection.

RESUMO

OBJECTIVE: The clinical features and outcomes of patients undergoing heart transplantation after a failed Fontan operation are still debated. The aim of this study was to retrospectively evaluate our experience in 14 patients undergoing heart transplantation after previous Fontan-type operations. METHODS: From 1990 to 2002, 14 patients underwent heart transplantation in our institution after a previous Fontan procedure. The mean age at the time of the Fontan operation and at transplantation was 7.3 +/- 2.8 and 17.2 +/- 6.3 years, respectively. The indication for transplantation was protein-losing enteropathy in 7 patients, arrhythmia with ventricular dysfunction in 5 patients, and heart failure in 2 patients. All patients received basic immunosuppressive therapy with cyclosporine (INN: ciclosporin) and azathioprine without induction therapy or maintenance steroids. RESULTS: Two hospital deaths occurred: one patient died on the fifth postoperative day of graft failure, and the second died on the 17th postoperative day after an acute neurologic event. Two patients died later, one 23 months after transplantation of acute rejection and the other after 90 months of chronic rejection and endocarditis. One patient underwent successful reintervention 2 years after heart transplantation for pulmonary vein obstruction. The 10 surviving patients are in New York Heart Association class I, with a mean follow-up of 64.5 +/- 42 months. One of them was delivered of a healthy baby 5 years after transplantation. Patients with protein-losing enteropathy reached a normal protein level within a mean of 10 months (range, 6-18 months) after transplantation. Four patients required a temporary administration (3-6 months) of oral steroid therapy for recurrent rejection episodes. Currently, 7 patients are taking cyclosporine, and 3 are taking cyclosporine and azathioprine. The actuarial survival at 1, 5, and 10 years was 86% +/- 9%, 77% +/- 12%, and 62% +/- 17%, respectively. CONCLUSION: Heart transplantation is a good option for patients with a failing Fontan operation. We documented the reversibility of protein-losing enteropathy in all patients. No mortality caused by surgical complications was observed.

RESUMO

OBJECTIVE: ST-segment elevation is frequently induced by dobutamine in patients with a recent myocardial infarction and may represent dyskinesia of the infarcted region or myocardial viability and ischaemia. Revascularization of the infarct-related artery may abolish myocardial ischaemia, and thus represents a useful tool to verify the significance of this finding. The aim of this study was to assess the relation between ST-segment elevation and wall motion response during dobutamine echo stress test and to evaluate the effect of coronary revascularization with percutaneous coronary angioplasty of the infarct-related artery on stress test results. METHODS AND RESULTS: Twenty-two patients (17 men; mean age 58+/-12 years) with a first acute myocardial infarction (5 anterior (23%) and 17 (77%) inferior) who showed ST-segment elevation during a dobutamine echo stress test performed early (7+/-5 days) after the acute event where included in the analysis. All patients underwent coronary arteriography followed by percutaneous revascularization with coronary angioplasty or atherectomy with or without stenting of the culprit lesion and a second dobutamine echo stress test at a mean of 40+/-20 days after revascularization. The minimal lumen diameter increased from 0.63+/-0.36 to 3+/-0.44 mm and % diameter stenosis decreased from 80+/-11 to 12+/-7 after revascularization. At baseline evaluation there were 62 normal moving segments (34%), 57 (32%) akinetic and 62 (34%) hypokinetic segments within the area at risk. Maximal ST-segment shift changed from a basal mean value of 0.41+/-0.6 to a peak value of 2.15+/-0.9 mm; angina developed in 6/22 patients (22%). A biphasic response to dobutamine indicative of myocardial ischaemia within the infarcted area was observed in 20/22 patients (91%) and in 54/74 (73%) segments showing wall motion abnormalities. After revascularization of the infarct-related artery 78 (43%) segments were considered to be normal, 46 (25%) akinetic and 57 (32%) hypokinetic. Dobutamine-induced ST-segment elevation in 6/22 cases (27%), but the amount of ST-segment shift at peak stress was significantly reduced (from 2.15+/-0.9 to 0.30+/-0.5 mm) and angina was present in 1 patient only (5%) despite a significant increase of double product compared to the pre-revascularization test (from 17,348+/-3536 to 21,005+/-4105, p < 0.003). At echocardiographic analysis, ischaemia involved only 4 segments (2%), 3 of them showing the persistence of a biphasic response to dobutamine. CONCLUSIONS: In patients with a recent myocardial infarction and no baseline dyskinesia dobutamine-induced ST-segment elevation in the infarct-related leads is usually associated with a biphasic response of wall motion within the infarcted region and may be considered an ancillary sign of myocardial ischaemia because it is abolished in the great majority of cases by successful revascularization of the infarct-related artery.
