RESUMO

The perception of social exclusion among patients with opioid use disorder (OUD) could be affected by long-term opioid use. This study explores the emotional and cardiac autonomic responses to an experience of ostracism in a sample of participants with OUD on opioid agonist treatment (OAT). Twenty patients with OUD and twenty healthy controls (HC) performed a ball-tossing game (Cyberball) with two conditions: Inclusion and Ostracism. We measured self-reported ratings of perceived threat towards one's fundamental needs and respiratory sinus arrhythmia (RSA) immediately after the game and 10 min after Ostracism (Reflective stage). Following ostracism, participants with OUD self-reported blunted feelings of threat to the fundamental need to belong. RSA levels were significantly suppressed immediately after ostracism and during the Reflective stage in comparison with HC, indicating an autonomic alteration in response to threatening social situations. Finally, only among HC higher perceived threats towards fundamental needs predicted increases in RSA levels, suggesting an adaptive vagal regulation in response to a perceived threat. Conversely, among patients with OUD the subjective response to ostracism was not associated with the autonomic reaction. OAT may have a protective effect against negative feelings of ostracism. However patients with OUD on OAT present poor autonomic regulation in response to social threats, which could reflect their trait hypersensitivity to social rejection.

RESUMO

Coastal amenities are public goods that represent an important attraction for tourism activities. This paper studies the capitalization effects of beach characteristics using hedonic pricing methods. We examine the implicit economic value of several beach characteristics like sand type, width, longitude, accessibility, or frontage in the Airbnb rental market. Using data for 16,663 Airbnb listings located in 67 municipalities of the Balearic Islands (Spain) during the summer of 2016, together with detailed information about the attributes of 263 beaches, our modelling approach considers interaction terms between the beach amenities and distance to the closest beach. Controlling for a set of listings' structural characteristics, host attributes and municipality fixed effects, we find that Airbnb guests attach economic value to beach length, the presence of vegetation, the type of coastal frontage and beach accessibility and exclusivity. However, there is no evidence of capitalization effects associated with beach width or the type of sand.

RESUMO

This research contributes to the literature on consumption displacement by exploring the pandemic-led shifts in hotel booking patterns. We perform a longitudinal analysis and a critical comparison of bookings before and after COVID-19 outbreak, focusing on the booking window, length of stay, and booking channel. Data include weekly bookings of a representative sample of Balearic Islands' hotels between 2018 and 2021. Results indicate that the pandemic has led to a drop in the volume of bookings and a remarkable change in booking patterns. Specifically, we find a temporal shift in booking behavior, characterized by a lower anticipation and a change in the tourism supply chain, namely a decrease in the share of intermediated bookings. The expected increase in the frequency of exogenous shocks, such as weather-related and sanitary crises, could affect purchasing behaviors, thus enhancing the relevance of this study, with managerial implications for industry and destination managers.

RESUMO

BACKGROUND: Individuals with Borderline Personality Disorder (BPD) feel rejected even when socially included. The pathophysiological mechanisms of this rejection bias are still unknown. Using the Cyberball paradigm, we investigated whether patients with BPD, display altered physiological responses to social inclusion and ostracism, as assessed by changes in Respiratory Sinus Arrhythmia (RSA). METHODS: The sample comprised 30 patients with BPD, 30 with remitted Major Depressive Disorder (rMDD) and 30 Healthy Controls (HC). Self-report ratings of threats toward one's fundamental need to belong and RSA reactivity were measured immediately after each Cyberball condition. RESULTS: Participants with BPD showed lower RSA at rest than HC. Only patients with BPD, reported higher threats to fundamental needs and exhibited a further decline in RSA after the Inclusion condition. CONCLUSIONS: Individuals with BPD experience a biased appraisal of social inclusion both at the subjective and physiological level, showing higher feelings of ostracism and a breakdown of autonomic regulation to including social scenarios.

RESUMO

ABL-class fusions other than BCR-ABL1 characterize around 2-3% of precursor B-cell acute lymphoblastic leukemia. Case series indicated that patients suffering from these subtypes have a dismal outcome and may benefit from the introduction of tyrosine kinase inhibitors. We analyzed clinical characteristics and outcome of 46 ABL-class fusion positive cases other than BCR-ABL1 treated according to AIEOP-BFM (Associazione Italiana di Ematologia-Oncologia Pediatrica-Berlin-Frankfurt-Münster) ALL 2000 and 2009 protocols; 13 of them received a tyrosine kinase inhibitor (TKI) during different phases of treatment. ABL-class fusion positive cases had a poor early treatment response: minimal residual disease levels of ≥5×10-4 were observed in 71.4% of patients after induction treatment and in 51.2% after consolidation phase. For the entire cohort of 46 cases, the 5-year probability of event-free survival was 49.1+8.9% and that of overall survival 69.6+7.8%; the cumulative incidence of relapse was 25.6+8.2% and treatment-related mortality (TRM) 20.8+6.8%. One out of 13 cases with TKI added to chemotherapy relapsed while eight of 33 cases without TKI treatment suffered from relapse, including six in 17 patients who had not received hematopoietic stem cell transplantation. Stem cell transplantation seems to be effective in preventing relapses (only three relapses in 25 patients), but was associated with a very high TRM (6 patients). These data indicate a major need for an early identification of ABL-class fusion positive acute lymphoblastic leukemia cases and to establish a properly designed, controlled study aimed at investigating the use of TKI, the appropriate chemotherapy backbone and the role of hematopoietic stem cell transplantation.

RESUMO

BACKGROUND: The EsPhALL2004 randomised trial showed a 10% advantage in disease-free survival for short, discontinuous use of imatinib after induction compared with no use of imatinib in patients with Philadelphia chromosome-positive acute lymphoblastic leukaemia receiving Berlin-Frankfurt-Münster chemotherapy and haemopoietic stem-cell transplantation (HSCT). Other contemporary studies showed an advantage from continuous protracted exposure to imatinib, challenging the indications to transplant. The EsPhALL2010 study was designed to assess whether imatinib given from day 15 of induction and continuously throughout chemotherapy led to a different outcome to that obtained in EsPhALL2004, despite decreasing the number of patients having HSCT. METHODS: This prospective, intergroup, open-label, single-arm clinical trial (EsPhALL2010) was done at 11 study groups across Europe, Chile, and Hong Kong. Patients aged 1-17 years with the translocation t(9;22)(q34;q11) who were recruited into national front-line trials for acute lymphoblastic leukaemia were eligible for this trial. Patients with abnormal renal or hepatic function or an active systemic infection were ineligible. Patients received imatinib 300 mg/m2 continuously from day 15 of induction during chemotherapy. Eligibility to HSCT depended on early morphological response and minimal residual disease. Imatinib was recommended throughout the first year after transplant. The co-primary endpoints were event-free survival and overall survival. All analyses were done in the intention-to-treat population. The trial is registered with the European Clinical Trials Database (EudraCT 2004-001647-30) and with ClinicalTrials.gov (NCT00287105) and is completed. FINDINGS: 158 patients were screened for eligibility, of whom 155 were enrolled between Jan 1, 2010, and Dec 31, 2014. 151 (97%) patients achieved first complete remission after induction and four after the consolidation phase, with 102 (66%) patients categorised as good risk and 53 (34%) as poor risk according to EsPhALL risk stratification criteria. 59 (38%) patients had HSCT during their first complete remission. 40 (26%) patients relapsed and 41 (26%) patients died during the study (25 [61%] during complete continuous remission, and 16 [39%] after relapse). The 5-year event-free survival was 57·0% (95% CI 48·5-64·6) and 5-year overall survival was 71·8% (63·5-78·5). 154 serious adverse events were reported in 80 (52%) of 155 patients. The most common toxicity was infection (61 [39%] patients, mostly bacterial); gastrointestinal disorders occurred in ten (6%) patients and osteonecrosis in eight (5%). Serious adverse events occurred mainly during high-risk blocks and delayed intensifications, including 14 fatal events (one in the consolidation phase, six in high-risk blocks, six in first delayed intensification, and one in second delayed intensification). INTERPRETATION: Although HSCT was done in a smaller proportion of patients in EsPhALL2010 than in EsPhALL2004, event-free and overall survival were similar between the two studies. Our data suggest that imatinib given early and continuously with intensive chemotherapy might increase toxicity.

RESUMO

The prognostic value of minimal residual disease (MRD) in Philadelphia-chromosome-positive (Ph+) childhood acute lymphoblastic leukemia (ALL) treated with tyrosine kinase inhibitors is not fully established. We detected MRD by real-time quantitative polymerase chain reaction (RQ-PCR) of rearranged immunoglobulin/T-cell receptor genes (IG/TR) and/or BCR/ABL1 fusion transcript to investigate its predictive value in patients receiving Berlin-Frankfurt-Münster (BFM) high-risk (HR) therapy and post-induction intermittent imatinib (the European intergroup study of post-induction treatment of Philadelphia-chromosome-positive acute lymphoblastic leukemia (EsPhALL) study). MRD was monitored after induction (time point (TP)1), consolidation Phase IB (TP2), HR Blocks, reinductions, and at the end of therapy. MRD negativity progressively increased over time, both by IG/TR and BCR/ABL1. Of 90 patients with IG/TR MRD at TP1, nine were negative and none relapsed, while 11 with MRD<5×10-4 and 70 with MRD≥5×10-4 had a comparable 5-year cumulative incidence of relapse of 36.4 (15.4) and 35.2 (5.9), respectively. Patients who achieved MRD negativity at TP2 had a low relapse risk (5-yr cumulative incidence of relapse (CIR)=14.3[9.8]), whereas those who attained MRD negativity at a later date showed higher CIR, comparable to patients with positive MRD at any level. BCR/ABL1 MRD negative patients at TP1 had a relapse risk similar to those who were IG/TR MRD negative (1/8 relapses). The overall concordance between the two methods is 69%, with significantly higher positivity by BCR/ABL1. In conclusion, MRD monitoring by both methods may be functional not only for measuring response but also for guiding biological studies aimed at investigating causes for discrepancies, although from our data IG/TR MRD monitoring appears to be more reliable. Early MRD negativity is highly predictive of favorable outcome. The earlier MRD negativity is achieved, the better the prognosis.

RESUMO

Endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) is a reliable and commonly established technique, enabling real-time guidance of transbronchial needle aspiration of mediastinal and hilar structures and parabronchial lung masses. As EBUS-TBNA became more available and adopted by clinicians, questions emerged about the optimal performance of the procedure. Although EBUS is considered safe, there are few complications that could occur during the test, correlated with both the procedure itself and the patient's characteristics. Moreover, this technique is often addressed to patients with overlapping airways diseases, which might have higher risk of complications during the procedure. Chronic obstructive pulmonary disease (COPD) patients could experience EBUS-TBNA with a relative high frequency due to their risk of developing lung cancer. The irreversible bronchial constriction characteristic of the disease raises some questions on premedication before bronchoscopic procedures. It is mandatory to optimize every aspect of the procedure in order to minimize the risk of complications, especially for fragile patients. Whether the use of inhaled bronchodilators before the procedure could improve the outcome of the procedure in COPD patients is reviewed in this article. No clear indication emerged from the literature suggesting the need of more studies in order to clarify this point.

RESUMO

INTRODUCTION: Autoimmune hemolytic anemia in children younger than 2 years of age is usually characterized by a severe course, with a mortality rate of approximately 10%. The prolonged immunosuppression following specific treatment may be associated with a high risk of developing severe infections. Recently, the use of monoclonal antibodies (rituximab) has allowed sustained remissions to be obtained in the majority of pediatric patients with refractory autoimmune hemolytic anemia. CASE PRESENTATION: We describe the case of an 8-month-old Caucasian girl affected by a severe form of autoimmune hemolytic anemia, which required continuous steroid treatment for 16 months. Thereafter, she received 4 weekly doses of rituximab (375 mg/m(2)/dose) associated with steroid therapy, which was then tapered over the subsequent 2 weeks. One month after the last dose of rrituximab, she presented with recurrence of severe hemolysis and received two more doses of rrituximab. The patient remained in clinical remission for 7 months, before presenting with a further relapse. An alternative heavy immunosuppressive therapy was administered combining cyclophosphamide 10 mg/kg/day for 10 days with methylprednisolone 40 mg/kg/day for 5 days, which was then tapered down over 3 weeks. While still on steroid therapy, the patient developed an interstitial pneumonia with Acute Respiratory Distress Syndrome, which required immediate admission to the intensive care unit where extracorporeal membrane oxygenation therapy was administered continuously for 37 days. At 16-month follow-up, the patient is alive and in good clinical condition, with no organ dysfunction, free from any immunosuppressive treatment and with a normal Hb level. CONCLUSIONS: This case shows that aggressive combined immunosuppressive therapy may lead to a sustained complete remission in children with refractory autoimmune hemolytic anemia. However, the severe life-threatening complication presented by our patient indicates that strict clinical monitoring must be vigilantly performed, that antimicrobial prophylaxis should always be considered and that experienced medical and nursing staff must be available, to deliver highly specialized supportive salvage therapies, if necessary, during intensive care monitoring.

RESUMO

BACKGROUND: Extracorporeal photochemotherapy (ECP) produces clinical improvements in refractory/resistant graft-versus-host disease (GvHD). Immunological mechanisms of ECP are still under investigation. METHODS: We have evaluated the changes in frequency and immunophenotype of circulating regulatory T cells (T-regs) in 10 patients undergoing allogeneic hematopoietic stem cell transplantation, receiving ECP for acute (n=4) or chronic (n=6) GvHD. T-regs were monitored for expression of surface CD4, CD25, GITR, CD45RO, CD62L and intracytoplasmic Foxp3. T-regs were sorted by fluorescence-activated cell sorting to perform functional assays by interferon (IFN)-gamma enzyme-linked immunospot and real-time quantitative polymerase chain reaction (RQ-PCR) to measure Foxp3, transforming growth factor (TGF)-beta, and interleukin (IL)-10 mRNA. RESULTS: ECP was accompanied by a significant increase of CD4+CD25+ T-regs after six procedures, increasing from 8.9% to 29.1% of total CD4 (P<0.05), with a simultaneous increase of glucocorticoid induced tumor necrosis factor receptor expression on CD4+CD25+ cells (from 15% to 40.8%, P<0.05). This increase was sustained after 12 procedures. T-regs expressed high levels of CD62L, CD45RO, and Foxp3. Sorted CD4+CD25+ T-regs were potently inhibitory toward the CD4+CD25- fraction, when matched with an allogeneic target (IFN-gamma secretion was reduced by 79%). Trans-well experiments showed that cell-to-cell contact was necessary to exert inhibitory activity. RQ-PCR revealed a significant expression of Foxp3 in CD4+CD25+ T-regs, but there was virtually no detection of TGF-beta and IL-10. GvHD improved in all patients, allowing tapering or discontinuation of immunosuppressive drugs. CONCLUSION: Our study shows a time correlation between ECP and increasing percentages of circulating functional T-regs. Albeit suggestive, our results need to be confirmed on larger series to determine the actual role of T-reg in mediating the clinical effect of ECP.
