Reduced intensity conditioning: enhanced graft-versus-tumor effect following dose-reduced conditioning and allogeneic transplantation for refractory lymphoid malignancies after high-dose therapy.

Non-myeloablative regimens have been proven to allow engraftment following allogeneic stem cells transplantation (allo-SCT) with minimal procedure-related toxicity. Conventional allo-SCT may produce remissions in patients with relapsed and refractory lymphoid malignancies (LM) but these good results may be achieved at the cost of high treatment-related morbidity and mortality. Application of allo-SCT using less intensive regimens may temper the frequency of these complications, allowing a potent graft-versus-tumor effect (GVT).

Induced expression of B7-1 on myeloma cells following retroviral gene transfer results in tumor-specific recognition by cytotoxic T cells.

The aim of this study was to evaluate whether tumor cells from patients with multiple myeloma activate allogeneic and autologous T cells. Results showed that myeloma cells expressed few B7-2 and no B7-1 in six cell lines and primary cells from 11 patients. They expressed substantial levels of HLA class I, CD40, and a set of adhesion molecules.

Large scale and clinical grade purification of syndecan-1+ malignant plasma cells.

For cancer immunotherapy, it is usually necessary to obtain a large number of tumor cells from patients. We have previously reported that syndecan-I is present only on malignant plasma cells in samples from patients with multiple myelomatosis. We report here that this antigen is cleaved by chymopapain.

Balance and stabilization capability of paraplegic wheelchair athletes.

The orientation of paraplegic athletes toward adapted sport activities required good knowledge of their functional characteristics. Wheelchair locomotion, especially for highly dynamic situations, poses the problem of trunk equilibrium management and head stabilization. The study aimed at designing a quantitative method to assess the ability of paraplegics to obtain trunk balance under dynamic stresses, and to analyze the various balance strategies, according to the spinal lesion level of the subjects.

Physical work load and its assessment among the nursing staff in nursing homes.

A study was conducted to investigate the physical work load and the prevalence of musculoskeletal complaints of nurses in nursing homes. Thirty-six female subjects selected from three nursing homes in the Netherlands participated in an observational study. In addition, the total nursing staff (n = 668) was invited to take part in a questionnaire survey (response was 94%).
