Combined Haploidentical and Umbilical Cord Blood Allogeneic Stem Cell Transplantation for High-Risk Lymphoma and Chronic Lymphoblastic Leukemia

Limited studies have reported on outcomes for lymphoid malignancy patients receiving alternative donor allogeneic stem cell transplants. We have previously described combining CD34-selected haploidentical grafts with umbilical cord blood (haplo-cord) to accelerate neutrophil and platelet engraftment. Here, we examine the outcome of patients with lymphoid malignancies undergoing haplo-cord transplantation at the University of Chicago and Weill Cornell Medical College. We analyzed 42 lymphoma and chronic lymphoblastic leukemia (CLL) patients who underwent haplo-cord allogeneic stem cell transplantation. Patients underwent transplant for Hodgkin lymphoma (n?=?9, 21%), CLL (n?=?5, 12%) and non-Hodgkin lymphomas (n?=?28, 67%), including 13 T cell lymphomas. Twenty-four patients (52%) had 3 or more lines of therapies. Six (14%) and 1 (2%) patients had prior autologous and allogeneic stem cell transplant, respectively. At the time of transplant 12 patients (29%) were in complete remission, 18 had chemotherapy-sensitive disease, and 12 patients had chemotherapy-resistant disease. Seven (17%), 11 (26%), and 24 (57%) patients had low, intermediate, and high disease risk index before transplant. Comorbidity index was evenly distributed among 3 groups, with 13 (31%), 14 (33%), and 15 (36%) patients scoring 0, 1 to 2, and ≥3. Median age for the cohort was 49 years (range, 23 to 71). All patients received fludarabine/melphalan/antithymocyte globulin conditioning regimen and post-transplant graft-versus-host disease (GVHD) prophylaxis with tacrolimus and mycophenolate mofetil. The median time to neutrophil engraftment was 11 days (range, 9 to 60) and to platelet engraftment 19.5 days (range, 11 to 88). Cumulative incidence of nonrelapse mortality was 11.6% at 100 days and 19 % at one year. Cumulative incidence of relapse was 9.3% at 100 days and 19% at one year. With a median follow-up of survivors of 42 months, the 3-year rates of GVHD relapse free survival, progression-free survival, and overall survival were 53%, 62%, and 65%, respectively, for these patients. Only 8% of the survivors had chronic GVHD. In conclusion, haplo-cord transplantation offers a transplant alternative for patients with recurrent or refractory lymphoid malignancies who lack matching donors. Both neutrophil and platelet count recovery is rapid, nonrelapse mortality is limited, excellent disease control can be achieved, and the incidence of chronic GVHD is limited. Thus, haplo-cord achieves high rates of engraftment and encouraging results.     

Utilizing a Sedation Decision Aid in Ambulatory Venous Access Device Placement: Effects on Patient Choice,Workup, and Recovery Time

This study was undertaken to determine the influence of using a sedation decision aid when selecting a sedation option for totally implantable vascular access device placement on patient choice, workup, and recovery time. An institutional review board-approved, Health Insurance Portability and Accountability Act-compliant, retrospective study of 76 patients (aged 23-89 years, 58% female) presenting to a vascular interventional radiology department between January 2, 2017, and May 5, 2017. Patients were given a decision aid that inquired about personal values and goals, and provided information about expectations; benefits; and risks of the options, including undergoing the procedure with no sedation (local anesthetic), minimal sedation (anxiolysis with a benzodiazepine), or moderate sedation (benzodiazepine and opiate). No sedation was selected by 15 out of 76 patients (19.7%), minimal sedation was selected by 26 out of 76 patients (34.2%), and moderate sedation was selected by 34 out of 76 patients (44.7%). Postprocedure recovery time differences were significant (P?<?.001) with a mean of 17.4 minutes for no sedation, 49.3 minutes for minimal sedation, and 70.8 minutes for moderate sedation. The use of a decision aid did not slow down the process because workup times were not significantly different: 15.9 minutes for no sedation, 22.1 minutes for minimal sedation, and 18.4 minutes for moderate sedation. Patient sedation preference for totally implantable vascular access device is variable, signifying there is a role for utilizing a decision aid because it empowers a patient to select the option most aligned with his or her goals. Influence on departmental flow is notable because this does not slow down the workup and a majority of patients choose no or minimal sedation, resulting in a decreased postprocedure recovery time burden.     

The Prone Position During Surgery and its Complications: A Systematic Review and Evidence-Based Guidelines

Surgery in the prone position is often a necessity when access to posterior anatomic structures is required. However, many complications are known to be associated with this type of surgery, as physiologic changes occur with increased pressure to anterior structures. While several studies have discussed postoperative vision loss, much fewer studies with lower levels of evidence have addressed other complications. A systematic literature review was conducted using 2 different databases, and 53 papers were regarded as appropriate for inclusion. Qualitative and quantitative analysis was performed. Thirteen complications were identified. Postoperative vision loss and cardiovascular complications, including hypovolemia and cardiac arrest, had the most number of studies and highest level of evidence. Careful planning for optimal positioning, padding, timing, as well as increased vigilance are evidence-based recommendations where operative prone positioning is required.Key words: Prone, Surgery, Trunk, Supine, Retinal, Complications, Evidence based medicine, Qualitative and quantitative methodsProne positioning is a common position used for access to the posterior head, neck, and spine during spinal surgery, access to the retroperitoneum and upper urinary tracts and access to posterior structures when required during plastic surgery.^1,2 Prone surgery is associated with a variety of complications many of which are derived from increased pressure on anterior structures. Rates of pressure sores as an intraoperative complication have been reported to be between 5% and 66%. As such, pressure sores incur longer hospital stays and healthcare costs.³ Postoperative vision loss can result from inappropriate orbital pressure and can also be a permanently debilitating condition. Lateral femoral cutaneous nerve neuropathy in 20% of spinal surgery cases causing pain and dysesthesia in the anterolateral thigh.⁴ Inappropriate pressure on vital structures of the abdomen can cause ischemia and organ failure, resulting in prolonged hospitalization, permanent disability, or death.⁵ Cardiovascular changes associated with prone surgery increase risk of intraoperative cardiac arrest. At the same time, prone surgery is also associated with airway management and CPR issues as access to anterior structures is limited.⁶
