Abstract
OBJECTIVE To investigate the effect of low-intensity pulsed ultrasound (LIPUS) on hematopoietic function in rats after combined chemotherapy with doxorubicin and cyclophosphamide. METHODS Eighty rats were randomized into control group and LIPUS group (n=40) for treatment with intraperitoneal injection of doxorubicin (2 mg/kg)+cyclophosphamide (20 mg/kg) for 4 consecutive days and continuous irradiation with LIPUS for 7 days following the injections, respectively. The white blood cells, red blood cells and platelets counts in each group were measured at 0, 4, 7, 9, 11, 14 and 18 days after the start of drug administration. The pathological sections of the bone marrow were examined at 0, 4 and 11 days, and the flow cytometry was performed for detecting the cell apoptosis; qPCR was performed for detecting the expressions of SCF, ICAM-1, and VCAM-1 mRNAs, and ELISA was used to detect the expressions of IL-3 and GM-CSF. RESULTS The white blood cell count was significantly higher in LIPUS group than in the control group (P < 0.05). Histopathological examination of the bone marrow revealed significantly increased hematopoietic tissue in LIPUS group (P < 0.05). Flow cytometry demonstrated an obviously lower cell apoptosis rate in the bone marrow in LIPUS group than in the control group (P < 0.05). Compared with those in the control group, the mRNA expression levels of ICAM-1 and VCAM-1 as well as the protein levels of IL-3 and GM-CSF were significantly increased in LIPUS group (P < 0.05). CONCLUSIONS LIPUS can alleviate the hematopoietic damage after combined chemotherapy with doxorubicin with cyclophosphamide probably by increasing the expressions of ICAM- 1, VCAM-1, IL- 3, and GM-CSF.

Abstract
Apheresis procedures are standard of care for a wide range of indications in children, collection of hematopoietic stem cells being the most frequent one. With increasing numbers of hematopoietic stem cell transplants, advances in graft manipulation techniques and the development of innovative therapies using immune effector cells and gene therapy, apheresis within the pediatric population is growing in demand. While young children have higher circulating white blood cell counts and robustly mobilize hematopoietic stem cells, apheresis machines were designed for use within the adult population and apheresis procedures in children, particularly small children, can be more challenging as vascular access, collection techniques and impact of extracorporeal volumes increase the rate of adverse events. In this article we review topics of particular relevance to hematopoietic stem cell and immune effector cell collections in small children.

Short-term side effects and attitudes towards second donation: A comparison of related and unrelated haematopoietic stem cell donors. J Clin Apher 2017; 33:226-235.

Abstract
The Nordic Register of Haematopoietic Stem Cell Donors (NRHSD) has registered related and unrelated donors from 10 transplant centres in Sweden, Norway, Finland and Denmark since 1998. We present a prospective, observational study of 1,957 donors, focusing mainly on the differences between related and unrelated donors. Related donors are reported to have more comorbidities, but similar side effects compared with unrelated donors. Side effects after BM or PBSC donation are generally of short duration and in this study no deaths, myocardial infarctions, splenic ruptures, or thromboembolic events are reported. Interestingly, related donors express more hesitancy towards donating again when asked 1 month after donation.
