Mindfulness in Adolescent and Young Adult (AYA) Patients Undergoing Hematopoietic Stem Cell Transplantation (HSCT): A Qualitative Study. Cancers (Basel) 2022; 14:cancers14112760. [PMID: 35681740 PMCID: PMC9179916 DOI: 10.3390/cancers14112760] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Revised: 05/27/2022] [Accepted: 05/31/2022] [Indexed: 02/04/2023] Open
Abstract
Simple Summary Previous research in adolescent and young adult (AYA) patients suggests that patients undergoing hematopoietic stem cell transplantation (HSCT) experience severe physiological stress and social challenges. Therapeutic mindfulness interventions have been associated with improved well-being; however, we are unaware of any study that has examined AYA HSCT patients’ therapeutic interests in improving quality of life. The goal of this study was to identify unmet needs, interests, and preferences for mindfulness and quality of life prior to, immediately following, and three months post HSCT to inform the development of a mindfulness-based stress reduction intervention. Results suggest a mindfulness-based intervention may be beneficial in improving quality of life and enhancing social engagement, particularly immediately following HSCT. Future AYA research may benefit from employing mindfulness-based techniques to improve quality of life and psychosocial outcomes in HSCT patients. Abstract Previous adolescent and young adult (AYA) research suggests patients undergoing hematopoietic stem cell transplantation (HSCT) experience severe physiological stress. The goal of this study was to identify unmet needs, interests, and preferences for mindfulness to inform the development of a mindfulness-based stress reduction intervention. Semi-structured interviews were conducted at three time points: prior to (n = 20), immediately after (n = 13), and three months post HSCT (n = 16) in the same AYA patients. Interviews assessed stress reduction strategies used, interest in mindfulness, and current quality of life. Three major thematic categories emerged from interview data across all time points: Concerns, Coping Strategies, and Mindfulness Activities. Prior to HSCT, two additional themes emerged including: Hope for the Future and Getting the Body Moving-Physical Activity. Most participants were not familiar with the term “mindfulness” prior to HSCT; but after being provided the definition of mindfulness, participants expressed interest in an online mindfulness-based intervention (e.g., ZOOM), stating: “I think it’s necessary” and “It would definitely be useful”. Participants suggested an intervention immediately following HSCT may decrease isolation concerns stating: “[in the hospital] You kind of feel like a hamster in a cage” and “you obviously have a lot of time to just be sitting by yourself in a hospital room”. The results suggest that a mindfulness-based online intervention is of interest to AYA HSCT patients and may be beneficial in decreasing physiological stress and improving quality of life.

Abstract
Purpose To establish Myh11 as a marker of a subset of corneal endothelial cells (CECs), and to demonstrate the feasibility of restoring the corneal endothelium with Myh11-lineage (Myh11-Lin[+]) adipose-derived stromal cells (ASCs). Methods Intraperitoneal administration of tamoxifen and (Z)-4-hydroxytamoxifen eyedrops were used to trace the lineage of Myh11-expressing cells with the Myh11-Cre-ERT2-flox-tdTomato mouse model. Immunostaining and Western blot characterized marker expression and spatial distribution of Myh11-Lin(+) cells in the cornea, and administration of 5-ethynyl-2'-deoxyuridine labeled proliferating cells. ASCs were isolated from epididymal adipose Myh11+ mural cells and treated with cornea differentiation media to evaluate corneal endothelial differentiation potential. Differentiated ASCs were injected into the anterior chamber to test for incorporation into corneal endothelium following scratch injury. Results A subset of CECs express Myh11, a marker previously thought restricted to only mural cells. Myh11-Lin(+) CECs marked a stable subpopulation of cells in the cornea endothelium. Myh11-Lin(+) ASCs undergo CEC differentiation in vitro and incorporate into injured corneal endothelium. Conclusions Dystrophy and dysfunction of the corneal endothelium accounts for almost half of all corneal transplants, the maintenance of the cornea endothelium is poorly understood, and there are a lack of mouse models to study specific CEC populations. We establish a mouse model that can trace the cell fate of a subpopulation of CECs based on Myh11 expression. A subset of ASCs that share this Myh11 transcriptional lineage are capable of differentiating into CECs that can incorporate into injured corneal endothelium, revealing a potential cell source for creating engineered transplant material.

Providing both autologous and allogeneic hematopoietic stem cell transplants (HSCT) may have a stronger impact on the outcome of autologous HSCT in adult patients than activity levels or implementation of JACIE at Belgian transplant centres. Bone Marrow Transplant 2019; 54:1434-1442. [PMID: 30696999 DOI: 10.1038/s41409-019-0458-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2018] [Revised: 01/09/2019] [Accepted: 01/09/2019] [Indexed: 12/29/2022]
Abstract
While performance since the introduction of the JACIE quality management system has been shown to be improved for allogeneic hematopoietic stem cell transplants (HSCT), impact on autologous-HSCT remains unclear in Europe. Our study on 2697 autologous-HSCT performed in adults in 17 Belgian centres (2007-2013) aims at comparing the adjusted 1 and 3-yr survival between the different centres & investigating the impact of 3 centre-related factors on performance (time between JACIE accreditation achievement by the centre and the considered transplant, centre activity volume and type of HSCT performed by centres: exclusively autologous vs both autologous & allogeneic). We showed a relatively homogeneous performance between Belgian centres before national completeness of JACIE implementation. The 3 centre-related factors had a significant impact on the 1-yr survival, while activity volume and type of HSCT impacted the 3-yr survival of autologous-HSCT patients in univariable analyses. Only activity volume (impact on 1-yr survival only) and type of HSCT (impact on 1 and 3-yr survivals) remained significant in multivariable analysis. This is explained by the strong relationship between these 3 variables. An extended transplantation experience, i.e., performing both auto & allo-HSCT, appears to be a newly informative quality indicator potentially conveying a multitude of underlying complex factors.

Abstract
Objectives Autologous peripheral blood stem cells transplantation (APBSCT) is a therapeutic option which can be used in various hematological, neoplastic disorders including lymphoproliferative disease (LPD). Differences in patient populations and treatment modalities in different transplant centers mean it is important to improve the knowledge of the different factors affecting engraftment after APBSCT for the success of this procedure. We sought to determine the factors influencing neutrophil and platelet engraftment after APBSCT in patients with LPD. Methods We conducted a retrospective review of 70 patients with LPD (35 with lymphoma and 35 with multiple myeloma) who had undergone APBSCT between January 2008 and December 2016. Data obtained included disease type, treatment, and stem cell characteristics. Kaplan-Meier analysis was performed for probabilities of neutrophil and platelet engraftment occurred and was compared by the log-rank test. The multivariate Cox proportional hazards regression model was used for the analysis of potential independent factors influencing engraftment. A p-value < 0.050 was considered statistically significant. Results Most patients were ethnic Malay, the median age at transplantation was 49.5 years. Neutrophil and platelet engraftment occurred in a median time of 18 (range 4–65) and 17 (range 6–66) days, respectively. The majority of patients showed engraftment with 65 (92.9%) and 63 (90.0%) showing neutrophil and platelet engraftment, respectively. We observed significant differences between neutrophil engraftment and patient’s weight (< 60/≥ 60 kg), stage of disease at diagnosis, number of previous chemotherapy cycles (< 8/≥ 8), and pre-transplant radiotherapy. While for platelet engraftment, we found significant differences with gender, patient’s weight (< 60/≥ 60 kg), pre-transplant radiotherapy, and CD34+ dosage (< 5.0/≥ 5.0 × 106/kg and < 7.0/≥ 7.0 × 106/kg). The stage of disease at diagnosis (p = 0.012) and pre-transplant radiotherapy (p = 0.025) were found to be independent factors for neutrophil engraftment whereas patient’s weight (< 60/≥ 60 kg, p = 0.017), age at transplantation (< 50/≥ 50 years, p = 0.038), and CD34+ dosage (< 7.0/≥ 7.0 × 106/kg, p = 0.002) were found to be independent factors for platelet engraftment. Conclusions Patients with LPD who presented at an early stage and with no history of radiotherapy had faster neutrophil engraftment after APBSCT, while a younger age at transplantation with a higher dose of CD34+ cells may predict faster platelet engraftment. However, additional studies are necessary for better understanding of engraftment kinetics to improve the success of APBSCT.

Abstract
Multiple factors contribute to transplant-related complications after high-dose chemotherapy followed by autologous peripheral blood stem cell transplantation, including conditioning regimens, number of infused stem cells and clinical characteristics of patient at transplant. We compared the transplant-related complications of 141 patients affected with hematological malignancies with those of 109 patients with solid tumors. The total number of peripheral blood stem cell transplantations performed was 339. High-dose chemotherapy mainly consisted of melphalan-, busulphan- or thiotepa-based regimens. Despite the equal number of infused CD34+ cells, patients with a hematological malignancy showed a slower absolute neutrophil count (days to neutrophils >0.5 x 109/L, 10.6 ± 3.6 for hematological malignancies versus 9.1 ± 1.2 for solid tumors, P <0.0001) and platelet recovery (days to platelets >20 x 109/L, 16.4 ± 9.8 for hematological malignancies versus 12.3 ± 4.1 for solid tumors, P <0.0001) than patients with a solid tumor. A significantly higher requirement of red blood cell (3.3 ± 4.1 versus 2.0 ± 1.9, P <0.0029) and platelet units (7.5_± 10.4 versus 4.2 ± 3.4, P <0.0001) was observed for hematological malignancies than for solid tumors. Five graft failures were documented exclusively in patients with a hematological malignancy. Moreover, such patients displayed a longer duration of mucositis (P <0.0028) and hospital stay (P <0.0001), but no difference was observed in terms of febrile episodes. Transplant-related mortality was similar between the two groups. In conclusion, patients with a hematological malignancy overall have more complications than those with a solid tumor.

Abstract
Patients with aggressive non-Hodgkin's lymphoma (NHL) who relapse after initial therapy have a poor prognosis and with standard dose salvage therapy the outlook remains poor. In this work we examine the patient characteristics and outcome of patients with aggressive NHL treated with HDT and autologous transplantation at our Institute from 1982 to 1999. A retrospective analysis was performed examining patient characteristics, prior chemotherapy regimens, pretransplant disease status, HDT regimen, source of stem cells, time for hematopietic recovery, complications of transplantation, response rates, overall survival (OS) and relapse-free survival (RFS). One hundred and thirty-four patients with aggressive NHL were treated with estimated 10-year OS and RFS rates of 50% and 66%, respectively. Disease status (sensitive vs. refractory) pre-HDT was the most powerful predictive parameter for OS and RFS, at both univariate and multivariate analysis. For the entire cohort, transplant-related mortality was only 3.5% without evidence of second malignancies. Our results confirm that HDT with autologous transplantation is associated with a durable RFS in a remarkable proportion of aggressive NHL patients with very low global early and late toxicity. Improved patient selection, transplant timing, ongoing improvements in supportive care, and selected phase III trials should increase outcomes further.

Abstract
The BMT program at Princess Margaret Hospital performed 105 transplants using cryopreserved peripheral blood stem cells (PBSC) from related allogeneic donors. The outcomes were compared with those of a historic control of 106 patients transplanted with freshly procured PBSC. The infusions were tolerated with limited toxicity related to nausea/vomiting or bradycardia, correlated with the total amount of DMSO infused. The average viability of the total nucleated cell (TNC) population after thawing was 71%. The survival of clonogenic progenitors amounted to 75% for colony-forming unit-granulocyte-macrophage (CFU-GM), 69% for burst-forming units erythroid (BFU-E), and 78% for colony-forming units granulocyte-erythrocyte-monocyte-megakaryocyte (CFU-GEMM). In contrast, colony-forming units megakaryocyte (CFU-MEG) was significantly more cryosensitive with recovery rates of 39%. The number of viable CD34(+) cells transplanted was correlated with the number of transplanted viable CFU-GM (P < .001), BFU-E (P < .001), CFU-MEG (P < .001), and CFU-GEMM (P = .049), but not with the TNC dose. The number of transplanted CD34(+) cells was correlated with engraftment of neutrophils (P = .012) and platelets (P = .013). The outcomes of cryopreseved or fresh PBSC transplants (PBSCT) with respect to engraftment of neutrophils (P = .178) and platelets (P = .785), lymphocyte recovery (P = .926), acute (P = .113), and chronic graft-versus-host disease (P = .673), recurrence (P = .295), nonrelapse mortality (P = .340), and overall survival (P = .668) were not significantly different. It is therefore reasonable to consider the option of cryopreserved allografts.

Abstract
The techniques of haemapheresis originated in the development of centrifugal devices separating cells from plasma and later on plasma from cells. Subsequently membrane filtration was developed allowing for plasma-cell separation. The unspecificity of therapeutic plasma exchange led to the development of secondary plasma separation technologies being specific, semi-selective or selective such as adsorption, filtration or precipitation. In contrast on-line differential separation of cells is still under development. Whereas erythrocytapheresis, granulocytapheresis, lymphocytapheresis and stem cell apheresis are technically advanced, monocytapheresis may need further improvement. Also, indications such as erythrocytapheresis for the treatment of polycythaemia vera or photopheresis though being clinically effective and of considerable importance for an appropriate disease control are to some extent under debate as being either too costly or without sufficient understanding of the mechanism. Other forms of cell therapy are under development. Rheohaemapheresis as the most advanced technology of extracorporeal haemorheotherapy is a rapidly developing approach contributing to the treatment of microcirculatory diseases and tissue repair. Whereas the control of a considerable number of (auto-) antibody mediated diseases is beyond discussion, the indication of apheresis therapy for immune complex mediated diseases is quite often still under debate. Detoxification for artificial liver support advanced considerably during the last years, whereas conclusions on the efficacy of septicaemia treatment are debatable indeed. LDL-apheresis initiated in 1981 as immune apheresis is well established since 24 years, other semi-selective or unspecific procedures, allowing for the elimination of LDL-cholesterol among other plasma components are also being used. Correspondingly Lp(a) apheresis is available as a specific, highly efficient elimination procedure superior to techniques which also eliminate Lp(a). Quality control systems, more economical technologies as for instance by increasing automation, influencing the over-interpretation of evidence based medicine especially in patients with rare diseases without treatment alternative, more insight into the need of controlled clinical trials or alternatively improved diagnostic procedures are among others tools ways to expand the application of haemapheresis so far applied in cardiology, dermatology, haematology, immunology, nephrology, neurology, ophthalmology, otology, paediatrics, rheumatology, surgery and transfusion medicine.

Abstract
BACKGROUND For surveillance of nosocomial bloodstream infections (BSIs) and pneumonia during neutropenia in adult patients who have undergone bone marrow transplantation (BMT) or peripheral blood stem cell transplantation (PBSCT), a multicenter study--the Hospital Infection Surveillance System for Patients with Hematologic/Oncologic Malignancies (ONKO-KISS)--was initiated in Germany in 2000. METHODS Nosocomial infections were identified in neutropenic patients by means of Centers for Disease Control and Prevention definitions for laboratory-confirmed BSI and modified criteria for pneumonia. RESULTS During the first 38-month period of the study (i.e., through December 2003), a total of 1899 patients associated with 28,273 neutropenic days were investigated. Of these, 1173 (62%) had undergone allogeneic and 726 (38%) had undergone autologous BMT or PBSCT. The mean duration of neutropenia was 14.9 days (9.6 and 18.1 days after autologous and allogeneic transplantation, respectively). Overall, 395 BSIs and 168 cases of pneumonia were identified. The pooled mean site-specific incidence density per 1000 neutropenic days was 14.0 for BSI (12.4 and 18.9 for the allogeneic and autologous transplantation groups, respectively) and 5.9 for pneumonia (6.1 and 5.6 in the allogeneic and autologous transplantation groups, respectively). After allogeneic transplantation, 22.4 BSIs per 100 patients and 11.0 cases of pneumonia per 100 patients occurred, whereas 18.2 BSIs per 100 patients and 5.4 cases of pneumonia per 100 patients occurred after autologous transplantation. The majority (57%) of pathogens associated with BSI were coagulase-negative staphylococci. CONCLUSIONS The ongoing ONKO-KISS project provides unprecedented reference data about the incidence of pneumonia and sepsis among BMT recipients and PBSCT recipients in Germany. These data will be used for further evaluation of the impact of hygiene measures and therapeutic regimens for these patients.

Abstract
BACKGROUND Hemopoietic stem cell transplantation, or HSCT, is an important tool in modern cancer treatment. Refinement of transplantation techniques and supportive care has resulted in increased posttransplantation survival rates. Dental care is a key supportive element in both pretransplantation and posttransplantation care of this patient population. METHODS The authors provide an overview of HSCT transplantation, emphasizing the oral complications and required supportive dental care. CONCLUSIONS It is critical that transplantation candidates undergo dental screenings and be treated adequately before transplantation, that their care be closely managed during the transplantation process, and that they be given dental support as soon as their recovery permits. Dentists should consult with the patient's oncologist or primary health provider to identify the appropriate timing and intensity of dental support. CLINICAL IMPLICATIONS Because of improved transplantation survival rates, more patients may seek supportive outpatient dental care after transplantation, which requires special management considerations. Dental professionals need to be knowledgeable about modern HSCT.

Abstract
Skin and hair follicle stem cell biology is the focus of increasing interest, not least because the adult hair follicle has well defined dermal and epithelial populations that display distinct developmental properties. Recent evidence suggests that a number of adult cell populations have much broader stem cell capabilities than previously thought. To examine whether this applied to the hair follicle, and with a view to developing the follicle as a stem cell model system we investigated whether adult hair follicles were capable of demonstrating haematopoietic stem cell activity. To investigate haematopoietic activity in hair follicles we first used in vitro haematopoietic colony assays. This demonstrated that rodent hair follicle end bulbs as well as micro-dissected dermal papilla and dermal sheath cells actively produced cells of erythroid and myeloid lineages but that follicle epithelial cells did not. As a more stringent test, we then transplanted cultured dermal papilla or dermal sheath cells from transgenically marked donor mice into lethally irradiated recipient mice and observed multi-lineage haematopoietic reconstitution when assayed at intervals of up to one year. Colony assays from bone marrow of primary recipients revealed that over 70% of clonogenic precursors were derived from donor hair follicle cells. When bone marrow from primary mice was harvested and used to repopulate secondary myeloablated recipients, multi-lineage haematopoietic engraftment was observed. Our data show that dermal but not epidermal compartments of the adult hair follicle have much broader stem cell activities than previously described. Although the treatment for many forms of blood disorder, such as leukemia, often requires transplantation of haematopoietic stem cells (HSC), their availability can be rate limiting. Given its easy accessibility, our identification of the hair follicle as a source of extramedullary haematopoietic stem cell activity makes it an attractive potential source for blood stem cell therapeutics and highlights its value as a model system in adult stem cell biology.

Abstract
To identify overall and site-specific rates of nosocomial infections (NIs) during the neutropenic, as compared to the non-neutropenic stage of treatment in adult recipients of allogeneic and autologous bone marrow transplantation (BMT) and peripheral blood stem-cell transplantation (PBSCT), a prospective, 54-month study was started at the Haematological Stem Cell Transplantation Unit of the University Hospital of Freiburg, Germany. NI types were identified using modified CDC definitions. A total of 351 patients (14 256 in-patient days, 5026 neutropenic days) were investigated (316/90% allogeneic, 35/10% autologous; BMT: 119 patients, PBSCT: 234 patients). The mean length of neutropenia was 14.3 days (range: 0-66). Antimicrobial prophylaxis for allogeneic transplantation consisted of ciprofloxacin, trimethoprim/sulpha-methoxazole, fluconazole, and metronidazole. In total, 239 NIs were identified in 169 patients (48.1%), and of these 171 (71.5%) occurred during neutropenia (34.0 NIs per 1000 days at risk). The main pathogens were coagulase-negative staphylococci (36.3%), Clostridium difficile (20.4%), and enterococci (10.0%). Site-specific incidence densities during neutropenia vs non-neutropenia were: 13.9 vs 1.6 bloodstream infections (all central line-associated), 11.9 vs 1.8 pneumonias, 3.0 vs 2.9 gastroenteritis, and 1.6 vs 0.3 urinary tract infections. The greatest number of NI in BMT and PBSCT recipients is acquired during neutropenia, and multicentre surveillance programmes should focus on this.

Abstract
A case of hepatitis B virus (HBV) reactivation after kidney transplantation is reported. The presence of antibodies against hepatitis B surface antigen (HBsAg) and hepatitis B core antigen (HBcAg) before transplantation indicated previous infection with HBV. Eight years after transplantation, a diffuse, large B-cell lymphoma occurred, and the patient was positive for HBsAg and hepatitis B e antigen, in association with normal activity of serum aminotransferases. Postmortem liver histology did not show any sign of portal tract or lobular inflammation despite the presence at immunostaining of extensive intranuclear and cytoplasmic positivity for HBcAg, indicating active viral replication. Natural immunity to HBV may not protect against reactivation in patients with a suppressed immune system. In this setting, periodic follow-up of HBV serology in patients at highest risk for HBV reactivation to allow for early diagnosis and prompt treatment with lamivudine is highly recommended.

Abstract
Glutamine supplementation of enteral and parenteral nutrition support has received increased attention in the research community over the past decade. Glutamine may become a conditionally essential nutrient during certain catabolic states, including after bone marrow transplantation (BMT). The administration of enteral or parenteral glutamine seems safe and also potentially efficacious in some patient groups undergoing intensive treatment for cancer. Studies indicate that adjunctive glutamine treatment may improve nitrogen retention, decrease clinical infection and length of hospital stay and reduce the incidence and severity of mucositis after BMT and high dose chemotherapy. Although not all studies demonstrate benefit, there are sufficient positive data to suggest that this nutrient should be considered in the metabolic support of many individuals undergoing the catabolic process of marrow transplantation. Given the available data, randomized, double-blind, controlled clinical trials of glutamine-enriched nutrition in patients receiving BMT and high dose chemotherapy protocols are indicated to further define the utility of this amino acid as adjunctive therapy. Studies of glutamine nutrition combined with current combinations of cytoreductive agents and hematopoietic growth factors in BMT will be particularly pertinent.
