Abstract
PURPOSE There are limited treatment options available for hematopoietic stem-cell transplant patients (HSCT) with oral graft-versus-host disease (GVHD). Intraoral phototherapy is a novel, yet promising therapeutic regimen. RESEARCH QUESTION To assess the safety and effectiveness of intraoral narrowband UVB (nbUVB) phototherapy in the treatment of oral GVHD. METHODS This case series evaluated 10 patients with refractory oral GVHD, who were treated at Northwestern Memorial Hospital with nbUVB between July 2019 and October 2023. Primary outcomes were to evaluate the safety and efficacy of phototherapy. Efficacy was measured by objective improvement in symptom scores and subjective improvement in patient reported symptoms. Safety was determined by the withdrawal due to adverse events. Total nbUVB exposure, number of treatments, and change in systemic immunosuppressive medications were also examined. RESULTS The study cohort comprised 10 patients who developed oral GVHD at a median of 9.5 months after HSCT. The total median dose of nbUVB was 36 J/cm2, and the median number of sessions was 55. All 10 patients demonstrated some degree of improvement in symptoms. Notably, there was a reduction in the number of patients who reported symptoms of oral pain (83%), bleeding (67%), xerostomia (50%), and oral sensitivity (78%) after initiating phototherapy. There was also a statistically significant decrease in the levels of pain, erythema, and edema (p ≤ 0.001, < 0.001, 0.01, respectively). Most patients tolerated phototherapy well, but 1 patient withdrew from treatment due to adverse effects. Seventy-five percent of patients who were on immunosuppressive medications were able to decrease or stop these medications. CONCLUSION This case series suggests that nbUVB phototherapy is well tolerated and efficacious in patients with oral GVHD.

Abstract
Influenza affects millions of people worldwide each year and can lead to severe complications, hospitalizations, and even death, especially among vulnerable populations such as older adults and those with chronic medical conditions. Annual vaccination is considered the most effective measure for preventing influenza and its complications. Despite the widespread availability of influenza vaccines, however, vaccination coverage rates remain suboptimal in several countries. Based on the latest scientific evidence and expert opinions on influenza vaccination in older people and patients with chronic disease, the Portuguese Society of Pulmonology (SPP), the Portuguese Society of Diabetology (SPD), the Portuguese Society of Cardiology (SPC), the Portuguese Society of Geriatrics and Gerontology (SPGG), the Study Group of Geriatrics of the Portuguese Society of Internal Medicine (NEGERMI-SPMI), and the Portuguese Society of Infectious Diseases and Clinical Microbiology (SPDIMC) discussed best practices for promoting vaccination uptake and coverage and drew up several recommendations to mitigate the impact of influenza. These recommendations focus on the efficacy and safety of available vaccines; the impact of influenza vaccination on older adults; patients with chronic medical conditions, namely cardiac and respiratory conditions, diabetes, and immunosuppressive diseases; and health care professionals, optimal vaccination timing, and strategies to increase vaccination uptake and coverage. The resulting position paper highlights the critical role that vaccinations play in promoting public health, raising awareness, and encouraging more people to get vaccinated.

Abstract
The sharing of clinical trial data and biomarker data sets among the scientific community, whether the data originates from pharmaceutical companies or academic institutions, is of critical importance to enable the development of new and improved cancer immunotherapy modalities. Through data sharing, a better understanding of current therapies in terms of their efficacy, safety and biomarker data profiles can be achieved. However, the sharing of these data sets involves a number of stakeholder groups including patients, researchers, private industry, scientific journals and professional societies. Each of these stakeholder groups has differing interests in the use and sharing of clinical trial and biomarker data, and the conflicts caused by these differing interests represent significant obstacles to effective, widespread sharing of data. Thus, the Society for Immunotherapy of Cancer (SITC) Biomarkers Committee convened to identify the current barriers to biomarker data sharing in immuno-oncology (IO) and to help in establishing professional standards for the responsible sharing of clinical trial data. The conclusions of the committee are described in two position papers: Volume I-conceptual challenges and Volume II-practical challenges, the first of which is presented in this manuscript. Additionally, the committee suggests actions by key stakeholders in the field (including organizations and professional societies) as the best path forward, encouraging the cultural shift needed to ensure responsible data sharing in the IO research setting.

Abstract
A secure Web-based bone marrow transplant (BMT) registry tool has been developed inside an existing portal for paediatric oncology. The registry ensures identity protection and facilitates data organization and analysis. The registration interface is based on a Portuguese translation of the International Bone Marrow Transplantation Registry (IBMTR) forms. The objectives are to improve the information flow in collaborative BMT research protocols and to facilitate registration of BMT patients, thus improving data analysis and statistics. The system imports pre-existing data from the patient registry on the portal and has an interface that guides the user about completing the data fields according to the diagnosis. It also performs real-time data validation. After completion, the information is kept on the database for future use and the system generates an IBMTR printout form, translated into English, to be sent to the IBMTR centre.

Abstract
Registries evaluating un-randomized patients have provided valuable information with respect to a therapy's utility, treatment practices, and evolution over time. While immunotherapy for cancer has been around for more than three decades, data collection in the form of a registry has not been undertaken. The authors believe that establishing a registry to study HD IL-2 immunotherapy, which has been the only systemic therapy producing long term unmaintained remissions for advanced kidney cancer and melanoma for over 20 years, will be an important resource in understanding the impact of immunotherapy with HD IL-2 in a rapidly changing therapeutic environment. Optimizing administration and improving selection of appropriate patients likely to benefit from HD IL-2 immunotherapy are two of many benefits to be derived from this endeavor.

Randomized clinical trial of therapeutic music video intervention for resilience outcomes in adolescents/young adults undergoing hematopoietic stem cell transplant: a report from the Children's Oncology Group. Cancer 2014; 120:909-17. [PMID: 24469862 DOI: 10.1002/cncr.28355] [Citation(s) in RCA: 113] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2013] [Revised: 07/19/2013] [Accepted: 08/08/2013] [Indexed: 12/12/2022]
Abstract
BACKGROUND To reduce the risk of adjustment problems associated with hematopoietic stem cell transplant (HSCT) for adolescents/young adults (AYAs), we examined efficacy of a therapeutic music video (TMV) intervention delivered during the acute phase of HSCT to: 1) increase protective factors of spiritual perspective, social integration, family environment, courageous coping, and hope-derived meaning; 2) decrease risk factors of illness-related distress and defensive coping; and 3) increase outcomes of self-transcendence and resilience. METHODS This was a multisite randomized, controlled trial (COG-ANUR0631) conducted at 8 Children's Oncology Group sites involving 113 AYAs aged 11-24 years undergoing myeloablative HSCT. Participants, randomized to the TMV or low-dose control (audiobooks) group, completed 6 sessions over 3 weeks with a board-certified music therapist. Variables were based on Haase's Resilience in Illness Model (RIM). Participants completed measures related to latent variables of illness-related distress, social integration, spiritual perspective, family environment, coping, hope-derived meaning, and resilience at baseline (T1), postintervention (T2), and 100 days posttransplant (T3). RESULTS At T2, the TMV group reported significantly better courageous coping (Effect Size [ES], 0.505; P = .030). At T3, the TMV group reported significantly better social integration (ES, 0.543; P = .028) and family environment (ES, 0.663; P = .008), as well as moderate nonsignificant effect sizes for spiritual perspective (ES, 0.450; P = .071) and self-transcendence (ES, 0.424; P = .088). CONCLUSIONS The TMV intervention improves positive health outcomes of courageous coping, social integration, and family environment during a high-risk cancer treatment. We recommend the TMV be examined in a broader population of AYAs with high-risk cancers.

Abstract
The aim of this study was to determine the effect of problem-solving education on self-efficacy and distress in informal caregivers of allogeneic hematopoietic stem cell transplantation patients. Patient/caregiver teams attended three 1-hour problem-solving education sessions to help cope with problems during hematopoietic stem cell transplantation. Primary measures included the Cancer Self-Efficacy Scale-transplant and Brief Symptom Inventory-18. Active caregivers reported improvements in self-efficacy (p < 0.05) and distress (p < 0.01) post-problem-solving education; caregiver responders also reported better health outcomes such as fatigue. The effect of problem-solving education on self-efficacy and distress in hematopoietic stem cell transplantation caregivers supports its inclusion in future interventions to meet the multifaceted needs of this population.

Abstract
The provision of therapeutic apheresis to children is a technically challenging procedure, requiring trained personnel and an understanding of the disease processes that leads to the need for apheresis. Most apheresis protocols are derived from studies in adult patients, even though most studies are of limited sample size. The focus of this review is to highlight the disease processes commonly treated with therapeutic apheresis in children, and to address the technical considerations pertinent to the provision of safe and effective apheresis in the pediatric setting.

Abstract
Despite of vast improvements in treatment, myocardial infarction often leads to heart failure (HF) which remains the leading cause of death in developed countries. Other than heart transplantation, therapeutic options have a limited role in improving out comes in patients with severe HF. It is therefore no surprise that cardiac cell therapy has raised many hopes as a novel therapeutic approach aimed at cardiac myocyte replacement/regeneration termed "cellular cardiomyoplasty". However, the ideal source, cell type, critical cell number, and mode of application for optimal therapeutic effect have not been defined thus far. Recent observations of the beneficial effect of cell transplantation in animal experiments have generated tremendous excitement and stimulated clinical studies suggesting that this approach is feasible, safe, and potentially effective in humans. Cell-based myocardial regeneration is currently being explored for a wide range of cardiac disease states, including acute and chronic ischemic myocardial damage, cardiomyopathy and as biological heart pacemakers. The main purpose of this article is to review recent literature on the use of various cells for the examination of their in vitro cardiogenic potential and their in vivo capacity to engraft and improve the functional properties of the infarcted heart.

Abstract
Background The population of survivors following allogeneic HSCT continues to increase, and yet their experiences of recovery and long-term survivorship have not been fully characterized. This paper presents a study protocol examining over time the functional status, psychosocial adjustment, health-related quality of life, and symptom experience of survivors who have undergone allogeneic transplantation. The aims of the study are to: 1) explore the patterns of change in these health outcomes during the survivorship phase; 2) characterize subgroups of survivors experiencing adverse outcomes; and 3) examine relationships among outcomes and demographic and clinical factors (such as age, graft-versus-host disease (GVHD), and disease relapse). Methods In this longitudinal observational study, adults who survive a minimum of 3 years from date of allogeneic transplantation complete a series of questionnaires annually. Demographic and clinical data are collected along with a series of patient-reported outcome measures, specifically: 1) Medical Outcomes Study SF- 36; 2) Functional Assessment of Chronic Illness Therapy (FACIT) - General, 3) FACIT-Fatigue; 4) FACIT- Spiritual; 5) Psychosocial Adjustment to Illness Scale; 6) Rotterdam Symptom Checklist-Revised; and 7) Pittsburgh Sleep Quality Index. Conclusions This study will provide multidimensional patient-reported outcomes data to expand the understanding of the survivorship experience across the trajectory of allogeneic transplantation recovery. There are a number of inherent challenges in recruiting and retaining a diverse and representative sample of long-term transplant survivors. Study results will contribute to an understanding of outcomes experienced by transplant survivors, including those with chronic GVHD, malignant disease relapse, and other late effects following allogeneic transplantation.

Abstract
BACKGROUND Transplanted hematopoietic progenitor cells (CD34+) have shown great promise in regenerative medicine. However, the therapeutic potential of transplanted cells is limited by their poor viability. It is well known that the microenvironment in which progenitors reside substantially affects their behavior. Because extracellular acidosis is a common feature of injured tissues or the tumor microenvironment and is a critical regulator of cell survival and activation, we evaluated the impact of acidosis on CD34+ cell biology. STUDY DESIGN AND METHODS Apoptosis was evaluated by fluorescence microscopy and binding of annexin V, hypodiploid cells, Bcl-xL expression, active caspase-3, and mitochondrial membrane potential was determined by flow cytometry. Colony-forming units were studied by clonogenic assays, and cell cycle was evaluated by flow cytometry. RESULTS Exposure of CD34+ cells to low pH (7.0-6.5) caused intracellular acidification, decreased cell proliferation, and triggered apoptosis via the mitochondrial pathway. Whereas exposure to thrombopoietin (TPO), stem cell factor (SCF), interleukin (IL)-3 or increases in cyclic adenosine monophosphate (cAMP) levels prevented CD34+ cell death induced by acidic conditions, granulocyte-macrophage-colony-stimulating factor, FMS-like tyrosine kinase 3-ligand, erythropoietin, and vascular endothelial growth factor had no effect. Despite their cytoprotective effect, CD34+ cell expansion triggered by TPO, SCF, or IL-3 was significantly impaired at low pH. However, a cocktail of these three cytokines synergistically supported proliferation, cell cycle progression, and colony formation. DISCUSSION Our findings indicate that an acidic milieu is deleterious for CD34+ cells and that a combination of certain cytokines and cAMP donors may improve cell viability and function. These data may be useful to develop new therapeutic strategies or to optimize protocols for regenerative medicine.

Abstract
OBJECTIVE The reduced intensity conditioning (RIC) stem cell transplantation is widely employed for the treatment of many hematologic malignancies, but the survival effectiveness is still unclear. This study conducted an updated meta-analysis to determine whether any significant difference could be found by using RIC vs. myeloablative conditioning (MAC) regimen for transplantation in patients with malignancies. METHODS We electronically searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and relevant articles (1987.01-2009.12). Comparative studies were carried out on clinical therapeutic effect of RIC and MAC on the survival outcomes and the transplantation-related complications. RESULTS We obtained 1776 records, and 29 studies totaling 6235 patients have been assessed. Compared with MAC regimen, the RIC regimen had a higher overall survival (OS) at one-yr and no difference at two-yr later after transplantation. RIC regimen had significantly lower rates of disease-free survival (DFS) after two-yr follow-up, lower incidences of ≥ II degree acute graft-versus-host disease (aGVHD), and lower TRM [OR, 0.61, 95% CI (0.53, 0.69)], but with a higher relapse rate [OR, 1.88(1.41, 2.51)]. No significant difference was found in rates of cytomegalovirus (CMV) infection and chronic GVHD between the regimens. CONCLUSIONS This meta-analysis confirmed that compared with MAC condition regimen, the RIC regimen had a consistently equivalent or even better rate in OS, but with lower DFS at longer follow-up.

Abstract
The study aimed at characterizing the profile of the drugs and identify combinations between potentially interactive anti-microbial drugs used in patients who underwent bone marrow transplantation (BMT). The analysis covered 70 prescription medications for BMT patients hospitalized at Instituto do Coração, São Paulo, Brazil. Medications were classified according to the Alpha system, listing their interactive potential and pharmacological characteristics according to literature. Data were analyzed through descriptive statistics. Results showed that 72.7% of drugs presented an interactive potential, with precipitators (79.2%) and fluconazole (85.7%), highlighted as the most involved anti-microbial in the combinations, associated to omeprazole in 40% of the samples. BMT patients were frequently administered combinations of potentially interactive drugs. This condition, when associated with simultaneous schedules, could predispose patients to undesirable events, thus affecting the security of the therapy.

Abstract
PURPOSE OF REVIEW Granulocyte colony-stimulating factor-mobilized peripheral blood stem cells are widely used to reconstitute hematopoiesis; however, preclinical and clinical studies show that improvements to this mobilization can be achieved. We discuss the development of new mobilizing regimens and evaluation of new findings on mobilized stem cell populations that may improve the utility and convenience of peripheral blood stem cell transplant. RECENT FINDINGS Chemokines and their receptors regulate leukocyte trafficking, and altering chemokine signaling pathways mobilizes stem cells. In recent trials, combination use of the chemokine (C-X-C motif) receptor 4 antagonist AMD3100 and granulocyte colony-stimulating factor mobilized more CD34 cells in fewer days than granulocyte colony-stimulating factor alone and allowed more patients to proceed to autotransplant. In preclinical studies the chemokine GRObeta synergizes with granulocyte colony-stimulating factor and when used alone or with granulocyte colony-stimulating factor mobilizes more primitive hematopoietic stem cells with less apoptosis, higher integrin activation, lower CD26 expression and enhanced marrow homing compared with granulocyte colony-stimulating factor. Hematopoietic stem cells mobilized by GRObeta or AMD3100 demonstrate superior engraftment and contribution to chimerism in primary and secondary transplant studies in mice, and peripheral blood stem cells mobilized by AMD3100 and granulocyte colony-stimulating factor in patients demonstrate enhanced engraftment capabilities in immunodeficient mice. SUMMARY Alternate regimens differentially mobilize stem cell populations with unique intrinsic properties with the potential to expand the utility of hematopoietic transplantation. Continued mechanistic evaluation will be critical to our understanding of mechanisms of mobilization and their use in regenerative medicine.

Abstract
Chronic diseases are both common and deadly. Due to the limitations of conventional therapies for chronic diseases such as advanced heart failure and diabetes mellitus, recent interest has been directed towards regenerative medicine. In this review, we examine the history of regenerative biology and emphasize the dynamic and multidisciplinary growth of this field. We highlight the spectrum of adult tissues that have a remarkable regenerative capacity (i.e., skeletal muscle) versus those that have a more limited regenerative capacity (i.e., heart). We further emphasize the use of relevant contemporary models for the study of regenerative biology (i.e., pancreatic regeneration), which highlight both the challenges for this field of study and the potential for regenerative medicine, including the use of cell-based strategies, to revolutionize medical therapies for chronic diseases.

Abstract
Stem cell research is currently focused on totipotent stem cells and their therapeutic potential, however adult stem cells, while restricted to differentiation within their tissue or origin, also have therapeutic utility. Transplantation with bone marrow hematopoietic stem cells (HSC) has been used for curative therapy for decades. More recently, alternative sources of HSC, particularly those induced to exit marrow or mobilize to peripheral blood by G-CSF, have become the most widely used hematopoietic graft and show significant superiority to marrow HSC. The chemokine/chemokine receptor axis also mobilizes HSC that occurs more rapidly than with G-CSF. In mice, the HSC and progenitor cells (HPC) mobilized by the CXCR2 receptor agonist GRObeta can be harvested within minutes of administration and show significantly lower levels of apoptosis, enhanced homing to marrow, expression of more activated integrin receptors and superior repopulation kinetics and more competitive engraftment than the equivalent cells mobilized by G-CSF. These characteristics suggest that chemokine axis-mobilized HSC represent a population of adult stem cells distinct from those mobilized by G-CSF, with superior therapeutic potential. It remains to be determined if the chemokine mobilization axis can be harnessed to mobilize other populations of unique adult stem cells with clinical utility.

Abstract
Congestive heart failure remains the leading cause of morbidity and mortality in the developed world. Current therapies do not address the underlying pathophysiology of this disease, namely, the progressive loss of functional cardiomyocytes. The notion of repairing or regenerating lost myocardium via cell-based therapies remains highly appealing. The recent identification of adult stem cells, including both cardiac stem/progenitor cells and bone marrow stem cells, has triggered an explosive interest in using these cells for physiologically relevant cardiomyogenesis. Enthusiasm for cardiac regeneration via cell therapy has further been fueled by the many encouraging reports in both animals and human studies. Further intensive research in basic science and clinical arenas are needed to make this next great frontier in cardiovascular regenerative medicine a reality. In this review, we focus on the role of bone marrow-derived stem cells and cardiac stem/progenitor cells in cardiomyocyte homeostasis and myocardial repair and regeneration, as well as provide a brief overview of current clinical trials using cell-based therapeutic approaches in patients with heart disease.

Abstract
High-dose cytotoxic chemotherapy followed by autologous haematopoietic stem cell transplantation (ASCT) is extensively used for the treatment of many haematopoietic, as well as several epithelial cancers. Disease relapse may be the result of tumour contamination within autograft as evidenced by gene marking studies. The multiple purging strategies that have been described to date have not proven effective in most ASCT settings. This review addresses the possibility of using oncolytic viruses as a novel purging strategy. DNA viruses such as genetically engineered adenoviral vectors have widely been used to deliver either a prodrug-activating enzyme or express wild-type p53 selectively in tumour cells in ex vivo purging protocols. In addition, conditionally replicating adenoviruses that selectively replicate in tumour cells and herpes simplex virus type 1 are other DNA viruses that have been tested as ex vivo purging agents under laboratory conditions. Vesicular stomatitis virus (VSV) and reovirus are naturally occurring RNA viruses that appear to hold promise as purging agents under ex vivo and in vivo settings. Preclinical data demonstrate reovirus's purging potential against breast, monocytic and myeloma cell lines as well as patient-derived tumours of diffuse large B-cell lymphoma, chronic lymphocytic leukaemia, Waldenstrom macroglobulinemia and small lymphocytic lymphoma. In addition, VSV has shown effective killing of leukaemic cell lines and multiple myeloma patient specimens. Given the increasing interest in the utilization of viruses as purging agents, the following review provides a timely summary of the potential and the challenges of oncolytic viruses as purging modalities during ASCT.

Abstract
The current study characterizes cognitive and psychiatric status in hematopoietic stem cell transplantation (HSCT) patients shortly before and after transplant. Thirty adult patients were assessed prospectively 1-2 weeks before transplantation and 100 days posttransplantation on neuropsychological and psychiatric measures. Before transplant, participants showed mild impairments on several neuropsychological measures, with the poorest performances occurring on learning and attention. Psychiatric functioning was significantly elevated compared with normative data. Significant improvements, however, were observed on neuropsychological measures by 100 days after transplant. Depression and anxiety scores also improved. Candidates for HSCT experienced mild diffuse cognitive dysfunction and psychiatric morbidity before the procedure, but these symptoms significantly improved by 3 months following their transplant in this small sample. Education about these possible pretransplant sequelae and the potential for rebound may be helpful to patients and families as they prepare for this treatment and the recovery period.

Abstract
Chemokines direct the movement of leukocytes, including hematopoietic stem and progenitor cells, and can mobilize hematopoietic cells from marrow to peripheral blood where they can be used for transplantation. In this review, we will discuss the stem cell mobilizing activities and mechanisms of action of GRObeta, a CXC chemokine ligand for the CXCR2 receptor. GRObeta rapidly mobilizes short- and long-term repopulating cells in mice and/or monkeys and synergistically enhances mobilization responses when combined with the widely used clinical mobilizer, granulocyte colony-stimulating factor (G-CSF). The hematopoietic graft mobilized by GRObeta contains significantly more CD34(neg), Sca-1+, c-kit+, lineage(neg) (SKL) cells than the graft mobilized by G-CSF. In mice, stem cells mobilized by GRObeta demonstrate a competitive advantage upon long-term repopulation analysis and restore neutrophil and platelet counts significantly faster than cells mobilized by G-CSF. Even greater advantage in repopulation and restoration of hematopoiesis are observed with stem cells mobilized by the combination of GRObeta and G-CSF. GRObeta-mobilized SKL cells demonstrate enhanced adherence to vascular cell adhesion molecule-1 and VCAM(pos) endothelial cells and home more efficiently to bone marrow in vivo. The marrow homing ability of GRObeta-mobilized cells is less dependent on the CXCR4/SDF-1 axis than cells mobilized by G-CSF. The mechanism of mobilization by GRObeta requires active matrix metalloproteinase-9 (MMP-9), which results from release of pro-MMP-9 from peripheral blood, and marrow neutrophils, which alters the stoichiometry between pro-MMP-9 and its inhibitor tissue inhibitor of metalloproteinase-1, resulting in MMP-9 activation. The efficacy and rapid action of GRObeta and lack of proinflammatory activity make it an attractive agent to supplement mobilization by G-CSF. In addition, GRObeta may also have clinical mobilizing efficacy on its own, reducing the overall time and costs associated with peripheral blood stem cell transplantation.

Abstract
The use of stem cell transplantation for severe autoimmune diseases refractory to conventional therapy arose from two discoveries: the excellent results of animal experiments, and serendipitous observations in human coincidental diseases. Experimental data and early phase I-II trials in highly selected patients suggest that highdose chemotherapy followed by autologous hematopoietic stem cell transplantation can arrest progression of severe autoimmune diseases with an acceptable risk/benefit ratio. The present article reviews the phase II-III prospective, multicenter, randomized trials that have been performed in distinct autoimmunediseases. In addition, allogeneic stem cell transplantation for autoimmune diseases is being cautiously explored in current protocols.

Abstract
As a novel neurotherapeutic strategy, stem cell transplantation has received considerable attention, yet little of this attention has been devoted to the probabilities of success of stem cell therapies for specific neurological disorders. Given the complexities of the cellular organization of the nervous system and the manner in which it is assembled during development, it is unlikely that a cellular replacement strategy will succeed for any but the simplest of neurological disorders in the near future. A general strategy for stem cell transplantation to prevent or minimize neurological disorders is much more likely to succeed. Two broad categories of neurological disease, inherited metabolic disorders and invasive brain tumors, are among the most likely candidates.

Abstract
Patients who undergo bone marrow transplantation (BMT) often report cognitive problems following treatment. This study used cognitive tests and a self-report measure of subjective cognitive complaints to determine (1) the rate of objective cognitive impairment in a sample of 65 BMT patients, and (2) the correspondence of patients' cognitive complaints to their actual cognitive performance. At 6 months following BMT, patients were assessed in seven cognitive domains--attention, verbal learning, verbal memory, visual memory, simple executive function, complex executive function, and psychomotor speed. Cognitive complaints were likewise assessed. In all, 51% had at least mild impairment (-1 standard deviation (s.d.) below published norms) in one or more cognitive domains, with 28% demonstrating moderate-to-severe impairment (-2 s.d.). Older patients and patients with lower IQ were more likely to score in the impaired range on objective cognitive tests, with males and the less educated showing trends toward scores in the impaired range. Younger patients made significantly more cognitive complaints. Total cognitive complaints were unrelated to average cognitive performance, and complaints in specific cognitive domains were largely unrelated to objective performance on corresponding domains. Findings suggest that patients who complain about their cognitive performance following BMT differ from those who experience actual deficits.

Abstract
National utilization data for hematopoietic stem-cell transplantation (HSCT) for childhood cancers in the United States have not been reported. We identified cancer encounters for children aged 18 years and younger from 1997 to 2001 in US nonfederal, acute care hospitals. We compared patient, hospital, and resource use characteristics and in-patient mortality associated with HSCT and non-HSCT encounters, estimated the number of HSCT encounters by stem-cell source and cancer type, and examined resource use and mortality in each category. We identified 461,175 cancer encounters, of which 6380 (1.4%) were HSCT encounters. There was wide variation in resource use and mortality by stem-cell source and cancer type. Of note, 17% of HSCT encounters were for patients with acute lymphoblastic leukemia without remission or sarcoma, conditions for which there is little evidence of benefit from HSCT in children. These encounters were associated with high in-patient mortality and long lengths of stay. Also, we observed an increasing use of cord blood over the study period. Future research should examine potentially important sociodemographic differences in patients undergoing HSCT compared to those who do not. Additional analyses incorporating disease stage and severity are needed.

Abstract
Despite current pharmacologic and whole organ transplantation strategies, advanced heart failure remains a common and deadly disease. Limited availability of donor organs for use in orthotopic heart transplantation has prompted the examination of alternative therapies, including cell transfer strategies. Stem cell populations have been identified in virtually all postnatal tissues with the exception of the heart, and these stem cells function in the maintenance and regeneration of the respective tissues. Recent studies challenge preexisting notions regarding cardiac repair and suggest that the heart is capable of limited regeneration through the activation of resident cardiac stem cells or the recruitment of stem cell populations from other tissues such as the bone marrow. This review highlights animal models that have the capacity for myocardial regeneration and examines potential sources of stem cell populations that may participate in tissue regeneration. While some authors view these cell-based strategies as a Fountain of Youth for the myopathic heart, future studies will decipher the regulatory mechanisms of stem cell populations and serve as a prelude to stem cell-based strategies.

Abstract
BACKGROUND AND OBJECTIVE Peripheral blood hematopoietic progenitor cell transplantation (PCT), both autologous and allogeneic, has been consolidated in the last decades as an important tool in the treatment of a number of oncohematologic malignancies. Nevertheless, there are scarce data about the real cost of the autologous procedure in our setting, and to date the economic impact of allogeneic PCT in our health system is unknown. PATIENTS AND METHOD In the present study a comparative analysis of the economic cost of both methods of PCT was carried out in a series of 67 consecutive patients who were eligible for autologous PCT (n = 48), or allogeneic PCT (n = 19) in a 2 year study period. The expenses derived from pretransplant studies, from the collection and processing of hematopoietic progenitors, and from the transplantation procedure itself were evaluated. RESULTS The collection of hematopoietic progenitors was significantly more expensive in autologous than in allogeneic PCT (p = 0.0001), owing both to the difficulty in the mobilization of such cells in patients who have been treated for the underlying disease and to the higher costs derived from the criopreservation of the collected material. Nevertheless, the costs of the pretransplant studies were significantly higher in allogeneic PCT due to the expenses of histocompatibility studies (p = 0.0001). Similarly, the costs derived from the transplantation procedure itself were significantly higher in allogeneic procedures (p = 0.0002) as those patients required a longer hospitalization, and also because of the higher number of patients requiring conditioning regimens including total body irradiation. CONCLUSIONS From these data we conclude that the real cost of PCT in our setting is 24,000 Euros for the autologous procedure, while it is 34,000 Euros in the context of allogeneic transplantation.

Abstract
PURPOSE OF REVIEW Chronic diseases are common and deadly. Stem cell therapies have received intense interest for the repopulation of damaged or diseased tissues. A detailed understanding of the similarities and differences between embryonic stem cells and somatic stem cells will enhance our understanding of mechanisms of tissue repair or cellular augmentation. In addition, emerging technologies will be useful in the definition of the molecular regulation of the respective stem cell populations. RECENT FINDINGS A number of postnatal tissues have a population of somatic stem cells, which function in the maintenance and repair of tissues. Using molecular technologies these somatic stem cell populations have been shown to be pluripotent when placed in a permissive environment. Recent studies have utilized emerging technologies to define a molecular signature of embryonic stem cells and selected somatic stem cell populations. These strategies will be useful for the definition of a molecular program that promotes a stem cell phenotype (i.e. stemness phenotype). SUMMARY Recent studies suggest that embryonic and somatic stem cell populations hold promise as sources for tissue engineering. The use of cell biological and molecular technologies will enhance our understanding of embryonic and somatic stem cell populations and their molecular regulatory events that promote multipotentiation.
