Abstract
BACKGROUND AND OBJECTIVES Number of total nucleated cells is an important prognostic factor of unrelated bone marrow transplantation. The objective of our study was to further optimize donor selection by finding donor characteristics which predict the total nucleated cell concentration in unrelated bone marrow products. MATERIAL AND METHODS Data were collected retrospectively from the pre-donation medical records. The outcome variable was concentration of total nucleated cells in the final products. We investigated several candidate predictors, including demographic variables and peripheral blood counts. A backward selection procedure was performed, using multivariable multilevel analysis. RESULTS A total of 471 donations were included. Significant predictors were increase of age (ratio per 5 years 0.971), cytomegalovirus (ratio 0.947 if positive), smoking (ratio 1.079 if yes), higher haemoglobin (ratio 1.052 per mmol/l), higher mono-nuclear cells (ratio 1.169 when mono-nuclear cells >2.69 compared to mono-nuclear cells <1.89 x 10E9/l), increasing number of whole blood donations (ratio 1.115 when blood donations >4 compared to blood donation <1), and larger body surface area (ratio 1.179 when body surface area >2.07 compared to body surface area <1.82 m(2)). The model was adjusted for collection volume. CONCLUSION Presence of all favourable factors was associated with a twofold higher concentration of total nucleated cells in the bone marrow harvest.

Abstract
Chlamydia trachomatis infections are responsible for the world's leading cause of blindness (trachoma) and its most prevalent sexually transmitted disease, which is strongly associated with pelvic inflammatory disease, ectopic pregnancy and tubal infertility. Twin study-based findings of members of EpiGenChlamydia Consortium estimate that there is a 40% genetic predisposition to C. trachomatis infections. It is likely that the advances in human genomics will help to unravel the genetic predisposition at the gene level and will help to define a genetic fingerprint that can be used as a marker for this predisposition. The information gathered to date suggests that this predisposition and the factors contributing to prognosis are multifactorial. The EpiGenChlamydia Consortium aims to structure transnational research to such a degree that comparative genomics and genetic epidemiology can be performed in large numbers of unrelated individuals. Biobanking and data-warehouse building are the most central deliverables of the Coordination Action of the Consortium in Functional Genomics Research. In addition, the collective synergy acquired in this Coordination Action will allow for the generation of scientific knowledge on the C. trachomatis-host interaction, knowledge on the genetic predisposition to C. trachomatis infection and the development of tools for early detection of a predisposition to C. trachomatis infection and its complications. This review summarizes the consortium aims and progress, and future perspectives and directions.

Abstract
BACKGROUND Perioperative red blood cell (RBC) transfusion may be associated with a poor prognosis in cancer surgery. Allogeneic leucocytes are assumed to play a causal role. This study evaluated the long-term effect of transfusion with leucocyte-depleted (LD) blood in patients with gastrointestinal cancer. METHODS The Transfusion Associated Complications = Transfusion Induced Complications? (TACTIC) study is a multicentre randomized controlled trial evaluating the short-term benefits of LD versus non-LD RBC transfusions. The present study evaluated 5-year survival and cancer recurrence among 512 patients with gastrointestinal cancer included in the TACTIC study. RESULTS Some 89.2 per cent of patients had a primary tumour and 79.7 per cent underwent surgery with curative intent; 243 patients received perioperative RBC transfusion (median 3 units). The 5-year overall survival rate of patients with any type of gastrointestinal cancer was 50.8 per cent in the LD group and 45.8 per cent in the non-LD group (P = 0.191). Corresponding 5-year disease-free survival rates were 60.0 and 56.6 per cent (P = 0.482), and recurrence rates 32.9 and 34.3 per cent (P = 0.864). CONCLUSION Leucocyte depletion is not associated with better long-term survival and lower recurrence rates in patients with gastrointestinal cancer.

Abstract
G-CSF/dexamethasone stimulated donor derived granulocyte transfusion (GTX) has been shown in non-randomized studies to be a useful co-therapy in immune-compromised patients unresponsive to conventional antimicrobial treatments. Reports of GTX are however usually single institution adult experiences. Substantiated pediatric data, other than in neonates, is less common.

Abstract
Over the past years, studies of unaffected first-degree relatives of schizophrenic patients have reported cognitive deficits in the domains of executive functions, memory, and attention. However, these deficits may rely on lower level information processing deficits. Here, we investigated visual information processing with a visual backward masking task. A vernier target was followed by a grating mask. Observers had to indicate the offset direction of the vernier. We determined the SOA between the vernier and the grating onset for schizophrenic patients, their healthy first order relatives, and a healthy control group. Schizophrenic patients needed SOAs about three times longer than healthy controls to reach a predefined criterion level. Backward masking performance of unaffected relatives was significantly better than the one of patients but significantly worse than performance of controls. This result adds further evidence that low level deficits as determined by visual backward masking are endophenotypes of schizophrenia.

Abstract
In the present study we used a simple visual evoked potential and a visual oddball paradigm to investigate alterations in the temporal integration of different frequency components such as alpha and theta oscillations in patients with schizophrenia. We found that neither the amplitude enhancement after stimulus onset nor the intertrial phase coherence was generally reduced in patients, but that the topography of the neural response was altered. While healthy controls elicited their maximum early alpha as well as late theta response over posterior electrode sites, the maximum response in patients was shifted to anterior electrode positions. This result was not found for the late theta response for targets as target processing was accompanied with frontal theta amplitude enhancement in healthy controls as well. The change of the topographical response pattern was mirrored by the intertrial phase coherence in both frequency bands. The findings imply that schizophrenia is related to multiple alterations in oscillatory networks. Even during simple tasks without high cognitive demands dysfunctional mechanisms of temporal and regional coordination appear to be of importance in schizophrenia.

Abstract
OBJECTIVE Determination of factors related to the need for transfusion in premature infants. DESIGN Descriptive. METHOD The need for transfusion in premature infants was determined in 2 academic centres: University Medical Center Utrecht and Leiden University Medical Center, The Netherlands. The data had been acquired in another study. The factors under study were: hospital, pregnancy duration, birth weight, gender, time of clamping of the umbilical cord, total volume of blood sampled for diagnostic purposes, number of days of mechanical ventilation, total duration of admission and duration of the admission to the Neonatal Intensive care unit. Both hospitals followed the national interdisciplinary practice guideline 'Blood transfusion'. RESULTS The total volume ofsampled blood for diagnosis, the duration of the mechanical ventilation and the admission period were related to a greater need for transfusion. On the other hand, the chance of transfusions diminished with longer pregnancy duration or increased birth weight. The difference in need for blood transfusion between both centres was significant. The total volume of transfused erythrocytes showed a strong correlation with the volume sampled for diagnostic procedures. CONCLUSION Anaemia in neonates is strongly related to the amount of blood taken for diagnostic procedures. Alternatives for blood transfusions in premature infants, and consequently for the reduction of the number of donors per child, are to be sought in delayed clamping of the umbilical cord, use of erythropoietin and use ofautologous umbilical cord blood.

Abstract
Monitoring of T cells involved in the alloimmune response after transplantation requires the availability of reliable in vitro assays for the detection of T cells with both direct and indirect allospecificity. While generally accepted assays exist to measure helper and cytotoxic T cells involved in direct allorecognition, consensus about an assay for monitoring indirect T-cell allorecognition in clinical transplantation is lacking. Many studies claim a relationship between the reactivity of T cells with indirect allospecificity and graft rejection, but different protocols are used and essential controls are often lacking. In this review, the disadvantages and pitfalls of the current approaches are discussed, in some cases supported by the results of our own in vitro experiments. We conclude that an international workshop is necessary to establish and validate a uniform, robust and reliable assay for the monitoring of transplant recipients and to study the actual role of indirect allorecognition in acute and chronic rejection.

Abstract
BACKGROUND Although delayed red cell engraftment and/or hemolysis have been thoroughly documented in association with ABO incompatibility between donor and recipient in patients undergoing hematopoietic stem cell transplantation (HSCT), there are no studies defining the general, long term clinical outcome in a large group of pediatric patients. METHODS We undertook a retrospective single center analysis of children undergoing pediatric allogeneic stem cell transplantation to determine the influence of ABO donor/recipient incompatibility. Outcome was analyzed according to donor type and included survival, graft versus host disease (GvHD), relapse, days of infection, antibiotic use, transfusion requirement and duration of hospital stay. RESULTS Two hundred and sixteen children (136 males; 80 females, aged 0-19) transplanted between January 1992 and December 2003 were included in the study. Indications for transplantation were hematological malignancies (n=179) and aplastic conditions (n=37). ABO compatibility was documented in 121 donor/recipient pairs. ABO incompatibility was documented in 95 donor/recipient pairs with 40 major, 40 minor and 15 bi-directional incompatible pairs. ABO incompatibility did not influence survival rate (P=0.3762), the incidence of GvHD (P=0.253) or rate of relapse (P=0.930). Recovery of leucocytes was influenced by ABO incompatibility (P=0.0493), but the rate of infection, transfusion requirements and duration of hospital stay are not. CONCLUSION In the pediatric setting, ABO major and/or minor mismatch between donor and recipient did not significantly influence the outcome of HSCT. The choice of donor should be determined by the degree of HLA match and CMV status in preference to ABO blood group compatibility.
