Home care during neutropenia after allogeneic hematopoietic stem cell transplantation in children and adolescents is safe and may be more advantageous than isolation in hospital

Brave new world: expanding home care in stem cell transplantation and advanced therapies with new technologies

Hematopoietic stem cell transplantation and cell therapies like CAR-T are costly, complex therapeutic procedures. Outpatient models, including at-home transplantation, have been developed, resulting in similar survival results, reduced costs, and increased patient satisfaction. The complexity and safety of the process can be addressed with various emerging technologies (artificial intelligence, wearable sensors, point-of-care analytical devices, drones, virtual assistants) that allow continuous patient monitoring and improved decision-making processes. Patients, caregivers, and staff can also benefit from improved training with simulation or virtual reality. However, many technical, operational, and above all, ethical concerns need to be addressed. Finally, outpatient or at-home hematopoietic transplantation or CAR-T therapy creates a different, integrated operative system that must be planned, designed, and carefully adapted to the patient's characteristics and distance from the hospital. Patients, clinicians, and their clinical environments can benefit from technically improved at-home transplantation.

What's New in Prevention of Invasive Fungal Diseases during Hospital Construction and Renovation Work: An Overview

The goal of the overview was to give insight into the recent data of invasive fungal diseases (IFDs) associated with construction and renovation in healthcare settings as well as the recent evidence about available prevention and infection control measures. The number of studies describing IFD outbreaks associated with construction or renovation is on the rise again. Applying adequate prevention measures is still a challenge not just for healthcare workers but also for architects and construction workers as well. The role of multidisciplinary teams in the planning and monitoring of prevention measures cannot be overemphasized. Dust control is an inevitable part of every prevention plan. HEPA filters are helpful in the prevention of fungal outbreaks in hematologic patients, but further studies are needed to clarify the extent in which they contribute as specific control measures. The cut-off value for a "threating" level of fungal spore contamination still remains to be defined. The value of antifungal prophylaxis is difficult to assess because other preventive measures are simultaneously applied. Recommendations are still based on few meta-analyses, a large number of descriptive reports, and the opinion of respective authorities. Outbreak reports in the literature are a valuable resource and should be used for education as well as for preparing outbreak investigations.

Outpatient allogeneic hematopoietic stem-cell transplantation: a review

Hematopoietic stem-cell transplantation (HSCT) is usually performed in well-equipped units inside a hospital. The cost of this in-hospital transplant is usually very high; therefore, this procedure is more difficult to perform in low- and middle-income countries. Autologous outpatient HSCT is now a common procedure; however, outpatient allogeneic transplants are more complicated. Only a few centers in the world have incorporated outpatient HSCT. This transplant requires special adaptation, like a day hospital, careful selection of patients, oral medications, and the patient must live relatively close to the hospital. The results until now suggest that this outpatient transplant is factible and similar to inpatient HSCT. The objective was to review and describe the different methods and results following an outpatient allogeneic-HSCT strategy.

Homecare Encounters: An Organizational Response to Innovative Care for Patients Undergoing Hematopoietic Stem Cell Transplantation During COVID-19

BACKGROUND

Healthcare delivery has been significantly changed because of the COVID-19 pandemic. Patients undergoing hematopoietic stem cell transplantation (HSCT) are vulnerable to infections because of their immunocompromised status. The risk of nosocomial infection may be reduced by providing care to patients at home.

OBJECTIVES

This article describes one cancer center's approach for delivering safe patient care through homecare encounters, the benefits of home care for HSCT, and future directions.

METHODS

Patients received detailed information on home encounters. Advanced practice providers visited patients daily and then returned to the clinic to formulate a plan of care with the interprofessional care team. Transplantation RNs visited patients on the same day to provide the prescribed care.

FINDINGS

Based on evaluations from 32 patients and 12 providers, the results indicated that home care was safe, feasible, and beneficial for patient care post-HSCT during the COVID-19 pandemic.

Long-term outcome in patients treated at home during the pancytopenic phase after allogeneic haematopoietic stem cell transplantation

Patients undergoing allogeneic haematopoietic stem cell transplantation (HSCT) were given the option to be treated at home during the pancytopenic phase. Daily visits by a nurse and phone calls from a physician from the unit were part of the protocol. During almost two decades, 252 patients with haematological malignancies and non-malignant disorders were included. Median age was 47 (range 0-72) years. Myeloablative conditioning was given to 102 patients and reduced intensity to 150. Donors were matched unrelated (n = 160), HLA-identical siblings (n = 71), or HLA-mismatched (n = 21). Cumulative incidence of acute graft-versus-host disease (GVHD) was 35% and that of chronic GVHD was 46%. Non-relapse mortality was 14% 10 years after HSCT. In patients with haematological malignancies (n = 229), the 10-year probability of relapse was 34%. No patients died at home. Overall survival was 59% and relapse-free survival was 50% after 10 years. We conclude that patients treated at home after HSCT have an encouraging long-term outcome.

Stem cell transplantation during cancer

Hematological malignancies account for approximately 9.5% of new cancers diagnosed annually. Lymphoma is the most frequent of all known categories of hematological malignancies. Worldwide, extensive research has focused on this type of cancer. However, new treatments are investigated in various clinical as well as pre-clinical studies. Hematopoietic stem cell transplantation (HSCT) is a recent and upcoming treatment strategy for patients with hematopoietic malignancies and inborn errors of metabolism or immune deficiencies. Recent studies have revealed that successful clinical outcome of this treatment strategy depends on multiple factors including the protocol applied, disease under treatment, health of the patient, source of the grafts, severity of complications such as graft versus host disease during grafting and associated infections. The scope of this review is to achieve greater understanding of various clinical effects of the disease and related mechanisms. The electronic database Pubmed was searched for pre-clinical as well as clinical controlled trials reporting efficacy of the HSCT against hematological malignancies.

Strategies before, during, and after hematopoietic cell transplantation to improve T-cell immune reconstitution

T-cell immune reconstitution (IR) after allogeneic hematopoietic cell transplantation (allo-HCT) is highly variable between patients and may take several months to even years. Patients with delayed or unbalanced T-cell IR have a higher probability of developing transplantation-related morbidity, mortality, and relapse of disease. Hence, there is a need for strategies to better predict and improve IR to reduce these limitations of allo-HCT. In this review, we provide an update of current and in-near-future clinically relevant strategies before, during, and after transplantation to achieve successful T-cell IR. Potent strategies are choosing the right HCT source (eg, donor-recipient matching, cell dose, graft manipulation), individualized conditioning and serotherapy (eg, antithymocyte globulin), nutritional status, exercise, home care, modulation of microbiota, enhancing homeostatic peripheral expansion, promoting thymopoiesis, and the use of adjuvant-targeted cellular immunotherapies. Strategies to prevent graft-versus-host disease are important as well because this complication and the subsequent need for immunosuppression affects T-cell IR and function. These options aim for personalized precision transplantation, where allo-HCT therapy is designed to boost a well-balanced T-cell IR and limit complications in individual patients, resulting in overall lower morbidity and higher survival chances.
