BACKGROUND: Cryoballoon ablation (CBA) as a first-line rhythm control strategy is superior to antiarrhythmic drugs (AADs) for preventing atrial fibrillation (AF) recurrence; the impact of first-line CBA on quality of life (QoL) and symptoms has not been well characterized. METHODS: Patients aged 18 to 75 with symptomatic paroxysmal AF naïve to rhythm control therapy were randomized (1:1) to CBA (Arctic Front Advance, Medtronic) or AAD (Class I or III). Symptoms and QoL were assessed at baseline, 1, 3, 6, 9, and 12 months using the EHRA classification and Atrial Fibrillation Effect on QualiTy-of-Life (AFEQT) and SF-36v2 questionnaires. Symptomatic palpitations were evaluated via patient diary. RESULTS: Overall, 107 patients were randomized to CBA and 111 to AAD; crossovers occurred in 9%. Larger improvements in the AFEQT summary, subscale and treatment satisfaction scores were observed at 12 months with CBA vs AAD (all P

Introduction Despite the high incidence of respiratory depression on the general care floor and evidence that continuous monitoring improves patient outcomes, the cost–benefit of continuous pulse oximetry and capnography monitoring of general care floor patients remains unknown. This study modeled the cost and length of stay savings, investment break-even point, and likelihood of cost savings for continuous pulse oximetry and capnography monitoring of general care floor patients at risk for respiratory depression. Methods A decision tree model was created to compare intermittent pulse oximetry versus continuous pulse oximetry and capnography monitoring. The model utilized costs and outcomes from the PRediction of Opioid-induced respiratory Depression In patients monitored by capnoGraphY (PRODIGY) trial, and was applied to a modeled cohort of 2447 patients receiving opioids per median-sized United States general care floor annually. Results Continuous pulse oximetry and capnography monitoring of high-risk patients is projected to reduce annual hospital cost by $535,531 and cumulative patient length of stay by 103 days. A 1.5% reduction in respiratory depression would achieve a break-even investment point and justify the investment cost. The probability of cost saving is ≥ 80% if respiratory depression is decreased by ≥ 17%. Expansion of continuous monitoring to high- and intermediate-risk patients, or to all patients, is projected to reach a break-even point when respiratory depression is reduced by 2.5% and 3.5%, respectively, with a ≥ 80% probability of cost savings when respiratory depression decreases by ≥ 27% and ≥ 31%, respectively. Conclusion Compared to intermittent pulse oximetry, continuous pulse oximetry and capnography monitoring of general care floor patients receiving opioids has a high chance of being cost-effective.

BACKGROUND The frequency and temporal distribution of postoperative respiratory depression (RD) events are not completely understood. This study determined the temporal distribution and frequency of RD episodes in postsurgical patients continuously monitored by bedside capnography and pulse oximetry. METHODS This was a post hoc study of a subset of postsurgical patients enrolled in The PRediction of Opioid-induced respiratory Depression In patients monitored by capnoGraphY (PRODIGY) trial from 2 sites in the United States. These patients had undergone continuous bedside monitoring on general care wards. These data were adjudicated for potential RD episodes. The number of RD episodes per patient and the time of each RD episode were determined. The first RD episode experienced by a patient was classified as an "initial" episode, and the initial and all subsequent RD episodes experienced by a patient were classified as "all" episodes. A PRODIGY risk score was calculated. RESULTS Data analyzed from 250 patients contained 2539 RD episodes in 155 (62.0%, 95% confidence interval, 55.7-68.0) patients with median 2 [0-8], range of 0-545 RD episodes per patient, with a PRODIGY risk score distribution of 100 (40.0%) low, 79 (31.6%) intermediate, 70 (28.0%) high (missing data from 1 patient). Median time to the initial RD episode was 8.8 [5.1-18.0] hours postoperatively. There was a peak occurrence of initial RD events between 14:00 and 20:00 on the day of surgery, and these were associated with a large number of subsequent events in the same timeframe. The peak time of all RD episodes occurred from 02:00 to 06:00. Patients with high PRODIGY risk scores had higher incidence and greater number of RD episodes per patient (P < .001, overall comparisons between groups for both incidence [χ2] and number of episodes [Kruskal-Wallis test]). CONCLUSIONS Continuous monitoring of surgical patients demonstrates that RD episodes are common, and risk increases with higher PRODIGY scores. In this patient cohort, the rate of initial RD episodes peaked in the afternoon to early evening, while peak rate of all RD episodes occurred in early morning. Further, among patients with RD episodes, the number of episodes increased with higher PRODIGY scores.

In our retrospective study, 16 patients affected by advanced cutaneous T cell lymphoma (CTCL) underwent allogeneic hematopoietic stem cell transplantation (HSCT). Two patients (12.5%) were in complete remission (CR), nine (56.3%) in partial remission (PR), and five (31.2%) with active disease. The patients were transplanted from an HLA-identical (n = 7) from a mismatched (n = 1) or haploidentical (n = 1) sibling, from matched unrelated donor (n = 5), or from a single cord blood unit (n = 2). Conditioning regimen was standard myeloablative in 6 patients and at reduced intensity in 10. Seven patients died from non relapse mortality (NRM) and four patients relapsed or progressed, three of them achieved a second CR after donor lymphocyte infusion (DLI) or chemotherapy plus DLI. To date, with a median follow-up of 76 months (range 6-130), nine patients are alive, eight in CR, and one with active disease. Overall survival (OS) and disease-free survival (DFS) at 1 and 10 years are 61% (95% CI 40-91%) and 54% (95% CI 33-86%), 40% (95% CI 22-74%), and 34% (95% CI 16-68%), respectively. The time from diagnosis to transplant seems to influence negatively both OS (log-rank p

Study objective: Opioid administration for pain in general care floor patients remains common, and can lead to adverse outcomes, including respiratory compromise. The PRODIGY trial found that among ward patients receiving parenteral opioids, 46% experienced >= 1 respiratory depression episode. The objective of this analysis was to evaluate the geographic differences of opioid administration and examine the association between opioid administration characteristics and the occurrence of respiratory depression.Design: Prospective observational trial.Setting: 16 general care medical and surgical wards in Asia, Europe, and the United States.Patients: 1335 patients receiving parenteral opioids.Interventions: Blinded, alarm-silenced continuous capnography and pulse oximetry monitoring.Measurements: Opioid-induced respiratory depression, defined as respiratory rate = 60 mmHg for >= 3 min; apnea episode lasting >30 s; or any respiratory opioid-related adverse event.Results: Across all patients, 58% received only long-acting opioids, 16% received only short-acting (= 3 h) opioids. The type and median total morphine milligram equivalent (MME) of opioid administered varied significantly by region, with 31.5 (12.5-76.7) MME, 31.0 (6.2-99.0) MME, and 7.2 (1.7-18.7) MME in the United States, Europe, and Asia, respectively (p < 0.001). Considering only postoperative opioids, 54% (N = 119/220) and 45% (N = 347/779) of patients receiving only short-acting opioids or only long-acting opioids experienced >= 1 episode of opioid-induced respiratory depression, respectively. Multivariable analysis identified post-procedure tramadol (OR 0.62, 95% CI 0.424-0.905, p = 0.0133) and post-procedure epidural opioids (OR 0.485, 95% CI 0.322-0.731, p = 0.0005) being associated with a significant reduction in opioid-induced respiratory depression.Conclusions: Despite varying opioid administration characteristics between Asia, Europe, and the United States, opioid-induced respiratory depression remains a common global problem on general care medical and surgical wards. While the use of post-procedure tramadol or post-procedure epidural opioids may reduce the incidence of respiratory depression, continuous monitoring is also necessary to ensure patient safety when receiving post-operative opioids.

The use of granulocyte colony-stimulating factor (G-CSF) primed bone marrow (G-BM) has been recently considered as an alternative to mobilized hematopoietic stem cells from peripheral blood (G-PB), especially in the haploidentical transplant setting. The purpose of this study was to compare the effect of in vivo G-CSF priming on BM and PB hematopoietic, mesenchymal (MSC), and immune cells. Forty healthy donors undergoing BM harvest for haploidentical transplant were given subcutaneous recombinant human G-CSF for 7 days. BM and PB samples were harvested on days -7 and 0. The hematopoietic stem/progenitor cells increased significantly after G-CSF priming in both BM and PB with a selective rise of BM CD34(+)CD38(-) cell subset. A striking enhancement of the mesenchymal progenitors was detected in G-BM. CD3(+), CD4(+), CD8(+), and CD19(+) cell fractions; the naive CD4(+) and CD8(+) subpopulations; and natural killer and regulatory T cells increased in G-BM, whereas only slight changes were detected in PB. Myeloid dendritic cells (DC1) were significantly up-regulated in both G-BM and G-PB, whereas DC2 increased only in G-BM. In conclusion, our results show substantial differences in the biologic effects exerted by G-CSF at BM and PB levels on hematopoietic cells and immune cell fractions. Furthermore, the impressive rise of MSC progenitors in G-BM might also be relevant to provide MSCs for several clinical use.

Hemorrhagic cystitis (HC) occurring after allogeneic transplantation significantly affects quality of life and, in some cases, becomes intractable, increasing the risk of death. To date, its therapy is not established. We used the hemostatic agent fibrin glue (FG) to treat 35 patients with refractory post-transplantation HC. Of 322 adult patients undergoing an allogeneic transplantation for hematological malignancy, 35 developed grade ≥ 2 HC refractory to conventional therapy and were treated with FG, diffusely sprayed on bleeding mucosa by an endoscopic applicator. The cumulative incidence of pain discontinuation and complete remission, defined as regression of all symptoms and absence of hematuria, was 100% at 7 days and 83% ± 7%, respectively, at 50 days from FG application. The 6-month probability of overall survival for all 35 patients and for the 29 in complete remission was 49% ± 8% and 59% ± 9%, respectively. In the matched-pair analysis, the 5-year probability of overall survival for the 35 patients with HC and treated with FG was not statistically different from that of the comparative cohort of 35 patients who did not develop HC (32% ± 9% versus 37% ± 11%, P = not significant). FG therapy is a feasible, effective, repeatable, and affordable procedure for treating grade ≥2 HC after allogeneic transplantation.

Conventional cytology (CC) of cerebrospinal fluid (CSF) fails to demonstrate malignant cells in up to 45 % of patients with acute lymphoblastic leukemia or lymphoblastic lymphoma (ALL/LL) in whom occult leptomeningeal disease is present. Flow cytometry (FCM) is considered more sensitive than CC, but clinical implications of CC negativity/CC positivity are not yet established. CSF samples from 38 adult patients with newly diagnosed ALL/LL were examined. Five (13 %) and nine (24 %) specimens were CC positive-FC positive (FCM(pos)/CC(pos)) and CC negative-FC positive (CC(neg)/FCM(pos)), respectively. The remaining 24 (63 %) samples were double negative (CC(neg)/FCM(neg)) (p = 0.001). CC(neg)/FCM(pos) patients showed a significantly shorter overall survival (OS) compared to CC(neg)/FCM(neg) ones. In multivariate analysis, the status of single FCM positivity was demonstrated to affect independently duration of OS (p = 0.005). In conclusion, FCM significantly improves detection of leptomeningeal occult localization in ALL/LL and appears to anticipate an adverse outcome. Further prospective studies on larger series are needed to confirm this preliminary observation.

Introduction Central venous catheters (CVC) related thrombosis (CRT) represents a well known complication in patients with acute myeloid leukemia (AML) receiving intensive chemotherapy but the efficacy of antithrombotic prophylaxis still remains controversial. Patients and Methods We analyzed 71 consecutive AML patients whose CVC was inserted before each chemotherapy cycle for an overall number of 106 CVC placements. In 47/106 insertions, a prophylaxis with 100 IU/kg/day low molecular weight heparin (LMWH) was administered for 7 days after CVC insertion and additional 7 after CVC removal. This unconventional dose of LMWH, although higher than usual, appeared adequate for a short-course approach. LMWH was delivered regardless of the platelet (PLT) count once provided that it should have been maintained above 20x109/L by transfusions. Results Of 106 insertions, we observed 19 (18%) episodes of CRT, 58 (54%) of sepsis and 50 (47%) infections of CVC-exit site with no difference between LMWH and no-LMWH group. Occurrence of CRT was significantly associated with CVC-exit site infections (14/19, p = 0.01) and sepsis (16/19, p = 0.005) with no difference between LMWH and no-LMWH group. In multivariate analysis, both CVC-exit site infections and sepsis were confirmed to be independent risk factors for CRT development. Conclusion Our retrospective study, although based on a small sample size, suggests that the occurrence of CVC-exit site infections and neutropenic sepsis following chemotherapy significantly increases the risk of CRT in AML, independently from the use of LMWH prophylaxis.
