Abstract
BACKGROUND Several commercial and academic autologous chimeric antigen receptor T-cell (CAR-T) products targeting CD19 have been approved in Europe for relapsed/refractory B-cell acute lymphoblastic leukemia, high-grade B-cell lymphoma and mantle cell lymphoma. Products for other diseases such as multiple myeloma and follicular lymphoma are likely to be approved by the European Medicines Agency in the near future. DESIGN The European Society for Blood and Marrow Transplantation (EBMT)-Joint Accreditation Committee of ISCT and EBMT (JACIE) and the European Haematology Association collaborated to draft best practice recommendations based on the current literature to support health care professionals in delivering consistent, high-quality care in this rapidly moving field. RESULTS Thirty-six CAR-T experts (medical, nursing, pharmacy/laboratory) assembled to draft recommendations to cover all aspects of CAR-T patient care and supply chain management, from patient selection to long-term follow-up, post-authorisation safety surveillance and regulatory issues. CONCLUSIONS We provide practical, clinically relevant recommendations on the use of these high-cost, logistically complex therapies for haematologists/oncologists, nurses and other stakeholders including pharmacists and health sector administrators involved in the delivery of CAR-T in the clinic.

Abstract
HSP90's are overexpressed in different cancer types and they probably are required to sustain aberrant signalling in malignant cells. Recently, pharmacological inhibition of HSP90 was found to suppress growth of myeloma cell lines and in primary myeloma cells. Therefore, we wanted to investigate the role of HSP90alpha and HSP90beta in the pathogenesis of malignant myeloma (MM) in more detail. Immunohistochemistry was employed to examine the expression of HSP90alpha and HSP90beta in MM. The importance of HSP90 for survival of MM -cells was investigated by SiRNA-mediated knockdown of HSP90 and blockade of the IL-6R/STAT3 and the MAPK signaling pathways in vitro. HSP90alpha and HSP90beta were overexpressed in majority of investigated MM cases, but not in MGUS or in normal plasma cells. SiRNA-mediated knockdown of HSP90 or treatment with the novel HSP90 inhibitor 17-DMAG attenuated the levels of STAT3 and phospho-ERK and decreased the viability of MM cells. The knockdown of HSP90alpha was sufficient to induce apoptosis. This effect was strongly increased when both HSP90s were targeted, indicating a cooperation of both. HSP90 critically contributes to myeloma survival in the context of its microenvironment and therefore strengthen the potential value of HSP90 as a therapeutic target.

Abstract
BACKGROUND There is an unexplained excess of cerebral palsy among male babies. There is also variation in the proportion of more severe cases by birth weight. It has recently been shown that the rate of cerebral palsy increases as intrauterine size deviates up or down from an optimum about one standard deviation heavier than population mean weight-for-gestation. AIMS To determine whether the gender ratio or the severity of cases also varies with intrauterine size. METHODS A total of 3454 cases of cerebral palsy among single births between 1976 and 1990 with sufficient data to assign case severity (based on intellectual impairment and walking ability) and to compare weight-for-gestation at birth to sex specific fetal growth standards, were aggregated from nine separate registers in five European countries. RESULTS The greater the degree to which growth deviates either up or down from optimal weight-for-gestation at birth, the higher is the rate of cerebral palsy, the larger is the proportion of male cases, and the more severe is the functional disability. Compared to those with optimum growth the risk of more severe cerebral palsy in male babies is 16 times higher for those with a birth weight below the 3rd centile and four times higher when birth weight is above the 97th centile. In contrast, for mild cerebral palsy in female babies the excess risks at these growth extremes are about half these magnitudes. CONCLUSIONS Among singleton children with cerebral palsy, abnormal intrauterine size, either small or large, is associated with more severe disability and male sex.

Abstract
Cerebral palsy (CP) is the commonest disabling impairment in childhood, with a prevalence of 2-3 per 1000 live births. The Danish Cerebral Palsy Registry is a research registry that contains cases of CP from birth year 1925 and has estimated the birth prevalence since 1950. Data on children with CP are collected from paediatric departments and one special institution for disabled children. The children are included by a child neurologist and an obstetrician, and information on pregnancy, birth, neonatal period, impairments and demographic data on the child and mother are registered in a standard form. The uptake area is eastern Denmark, covering about 50% of the population, but the rest of Denmark is planned to be included from 2001. The Registry is large, well established and validated, and the definitions and collection procedures have not changed through several decades. It therefore has great research potential. Birth prevalence is estimated continuously, and changes over time are analysed and correlated with pre- and perinatal conditions. A correlation between increased survival of preterm babies and an increased prevalence was found previously, and a decreased prevalence in very preterm infants was later associated with less use of mechanical ventilation. A study correlating CP and maternal infection is ongoing. Collaboration between 14 European CP registries allows the true differences in prevalence between different countries to be studied. Linkage to other individually based registries in Denmark will allow the social consequences of CP to be described.

Abstract
The Cerebral Palsy Register in eastern Denmark has collected cases using a uniform data sampling procedure since birth year 1979. We have investigated changes in the rate of cerebral palsy, related to gestational age, mortality and perinatal risk factors in children born 1983--90. The total cerebral palsy birth prevalence decreased from 3.0 in the birth year period 1983--86 to 2.4 per 1000 live births (P < 0.01) in 1987--90, owing to a decrease among all preterm infants (29--19 per 1000, P < 0.001). The perinatal and early neonatal mortality in preterm infants was unchanged from 1983--86 to 1987--90. The rate of cerebral palsy in term infants was 1.5 per 1000 in all birth-year periods from 1979--90. Among the cerebral palsy infants, the proportion of very preterm babies treated with mechanical ventilation in the neonatal period decreased from 95% in 1983--86 to 61% in 1987--90 (P < 0.001), while the group treated with CPAP among the moderately preterm babies increased from 61% to 78% (P < 0.05). The significant decline in cerebral palsy rate in preterm infants born 1987--90 may be due to a change in treatment at the neonatal intensive care units using less mechanical ventilation, a hypothesis which needs further investigation.

Abstract
OBJECTIVE To examine the relation between breech delivery and cerebral palsy, considering the influence of intrauterine growth, low Apgar score at birth, and mode of delivery. DESIGN Register-based, case-control study. POPULATION A cohort of infants with cerebral palsy born between 1979 and 1986 in East Denmark, identified by linkage of the cerebral palsy register with the national birth register. Discharge letters from births of breech infants with cerebral palsy were reviewed. MAIN OUTCOME MEASURES Presentation, mode of delivery, gestational age, birthweight, Apgar score, type of cerebral palsy, severity of handicap. RESULTS Breech presentation at term was associated with a borderline significantly higher risk of cerebral palsy than vertex presentation (OR 1.56; 95% CI 0.9-2.4). Breech presentation infants more often had a lower Apgar score (< 7 at 5 minutes) and were smaller for gestational age (SGA < 2 SD) than were those with vertex presentation; infants with a low Apgar score, or who were small for gestational age, had a higher risk of cerebral palsy. After stratification by being small for gestational age the risk of cerebral palsy was not related to presentation. There were no differences between breech and vertex infants with cerebral palsy in terms of low Apgar score, being small for gestational age, mode of delivery, and severity of the handicap. Breech presentation infants were more often classified as diplegic (77.8% versus 42.3% in cephalic infants). CONCLUSION The risk of cerebral palsy among term breech presentation infants does not seem to be related to mode of delivery, but is more likely linked to a higher rate of being small for gestational age in breech infants.

Abstract
BACKGROUND Preterm infants are at 8 times higher risk than term infants for pre- and perinatal brain damage, resulting in cerebral palsy. In this paper we have analysed the influence of prenatal and birth-related risk factors on cerebral palsy in preterm infants. METHODS In a register-based study, 175 preterm singleton infants with cerebral palsy, born in 1982-86, were compared with 687 controls matched by gestational age and year of birth. RESULTS Statistically significant higher rates in cases were found in parity > or = 3 (22% vs. 16%, p < 0.05), Cesarean section (67% vs. 56%, p < 0.01), and low Apgar scores at 1 minute (45% vs. 36%, p < 0.05). By multivariate analyses, two variables remained statistically significant: parity > or = 3 (adjusted OR = 1.53 (95% CI 1.00-2.34), p < 0.05) and Cesarean section (adjusted OR = 1.57 (95% CI 1.07-2.32), p < 0.05). CONCLUSIONS Pregnancy complications preceding preterm birth did not imply a higher risk of cerebral palsy. Delivery by Cesarean section was a prognostic factor for developing cerebral palsy, and the predictive value of Apgar scores was highly limited.

Abstract
To investigate changes in cerebral palsy birth prevalence and perinatal mortality rate by different gestational age groups, 1979-86, cerebral palsy cases in eastern Denmark were identified from the Danish Cerebral Palsy Register, and information on birth and mortality rates was sought in the Danish Medical Birth Register. From 1979-82 to 1983-86, the birth prevalence of cerebral palsy increased from 2.6 to 3.0 per 1000 (P < 0.05). The rate for infants of 31 weeks' gestation or more did not change, whereas a significant increase was observed in infants below 31 weeks (85-123 per 1000, P < 0.05). In the same periods, perinatal mortality in eastern Denmark decreased significantly from 8.6 to 7.8 per 1000. The decrease in stillbirth rate was significant in all subgroups of gestational ages except in those of 28-30 weeks' gestation. The early neonatal mortality rate decreased significantly only in infants below 31 weeks (282-239 per 1000, P < 0.05). Thus, in eastern Denmark, cerebral palsy birth prevalence has increased from birth-year period 1979-82 to 1983-86 because of an increased rate in preterm infants below 31 weeks, who at the same time had a reduced risk of early neonatal death.

Abstract
OBJECTIVES To analyse completeness and validity of data in the Cerebral Palsy Register in Denmark, 1979-1982. METHODS Completeness has been assessed by comparing data from The Danish National Patient Register (DNPR) with the cases included in the Cerebral Palsy Register (CPR). Agreement between 12 variables in the CPR and obstetrical medical records has been analysed using kappa-statistics. RESULTS Of 468 children in the DNPR, only 237 fulfilled the inclusion criteria of the CPR; and 35 (15%) of these cases had not been reported to the CPR. Data agreement was generally good, but gestational age was subject to a systematic error, and urinary infections in pregnancy (kappa = 0.43) and placental abruption (kappa = 0.52) were seriously under-reported in the CPR. CONCLUSIONS Completeness of the Cerebral Palsy Register in Denmark, 1979-1982, has been assessed to maximal 85%, emphasizing the impact of using supplementary case ascertainment sources in the future. Validity of data varied according to definition and significance of the specific variable.

Abstract
Immunomagnetic separation using anti-CD34 monoclonal antibodies and paramagnetic microspheres has been used to enrich hematopoietic stem cells from human bone marrow, whole cord blood, or mobilized peripheral blood mononuclear cell collections. This method has been reported to achieve high separation purity of CD34+ cells in small scale experiments with fresh material. The aim of the present study was to compare the efficacy of the CD34+ cell selection technique, when thawed bone marrow or fresh peripheral blood mononuclear cells were enriched. Starting with thawed bone marrow containing 2.9% CD34+ cells the final product purity was 67.7% with a 6% CD34+ cell yield (enrichment factor 25.7), and a 85-fold CFU-GM enrichment. Using fresh mobilized peripheral blood mononuclear cells the released cells contained 77.6% CD34+ cells with a 47% yield (enrichment 86.5-fold), and a 46-fold CFU-GM enrichment. These results indicate that CD34+ cells can be selected from cryopreserved bone marrow using immunomagnetic procedures. However, fresh leukapheresis products seem to be a much better material for a positive immunomagnetic stem cell selection technique in terms of purity, yield and enrichment.

Abstract
The colon carcinoma cell line HT-29 was used to explore the potential of interleukin-4 (IL-4) and tumor necrosis factor alpha (TNF-alpha) to modify integrin expression and adhesive functions of tumor cells in vitro and to examine corresponding metastatic effects in vivo. Preincubation of HT-29 cells with 100 U/ml of IL-4 for 48 h downregulated the surface expression of the integrin subunits alpha 2, alpha 3, beta 1 and beta 4 after 48 h, whereas the alpha 1 subunit was upregulated. In contrast, 100 U/ml to TNF-alpha selectively upmodulated the expression of alpha v. Attachment to fibronectin of cells treated with IL-4 increased twofold (63.5% vs 32.4%). Adhesion to fibronectin (54.0% vs 32.4%) and vitronectin (37.9% vs 16.4%) was elevated in the case of TNF-alpha stimulation. Using an experimental metastasis model, HT-29 cells showed a significant reduction of their lung-colonizing potential in nude mice when preincubated with IL-4 for 48 h before intravenous injection. The decrease also observed for TNF-alpha-treated cells was less pronounced. The data indicate that the cytokines IL-4 and TNF-alpha can act as direct regulators of adhesive mechanisms of tumor cells bearing adequate receptors, thus influencing lung-colony formation.

Abstract
In a case-control study, gestational age and intrauterine growth of 191 preterm singleton infants 1971-82 with cerebral palsy were compared to all preterm live-born singletons in Denmark in 1982 (N = 2203). The distribution of gestational age among preterm cases was slightly bimodal with maximum values at 29 and 32 weeks. The risk for cerebral palsy was highest in the infants with gestational age 28-30 weeks (OR = 5.6 (4.0-7.8), 95% confidence interval). Birth weight deviation, in the 34-36 weeks infants, expressed as the number of standard deviations from the mean birth weight for gestational age, was more negative in cases than in controls (P < 0.001). The frequency of small for gestational age (SGA) was 13% in cases and 9% in controls (OR = 1.5 (0.96-2.3), 95% confidence interval). The odds for cerebral palsy being SGA, was lower in 28-30 weeks (OR = 0.22 (0.06-0.86), 95% confidence interval), the same in 31-33 weeks (OR = 0.83 (0.35-2.0), 95% confidence interval) and higher in 34-36 weeks (OR = 5.2 (2.9-9.5), 95% confidence interval). In conclusion, preterm infants with cerebral palsy are born earlier than other preterm infants. Small for gestational age is associated with cerebral palsy in preterm infants only above 33 weeks.

Abstract
In this study we report that recombinant human (rh) interleukin-1alpha (IL-1alpha) has direct and dose-dependent growth-modulating effects on human tumor cell lines in vitro as measured by a human tumor cloning assay (HTCA). Colony formation of the melanoma cell line A 375 was inhibited by rhIL-1alpha, whereas colony formation of the glioblastoma cell line HTB 14 was enhanced by this cytokine. Both growth-modulating effects were dose-dependent, however with some saturation. Subsequently, we have tested the activity of recombinant human IL-1 receptor antagonist (rhIL-1ra) on the tumor growth modulation by rhIL-1alpha. Tumor cells were incubated with increasing concentrations of rhIL-1ra and then added to the cultures containing rHIL-1alpha. Concentrations of rhIL-1ra were chosen to achieve a range between 0.01 and 100 ng/ml which includes a 1000-fold molar excess over IL-1alpha. The receptor antagonist was able to block both the inhibition and the stimulation of clonal growth of the respective tumor cell line by rhIL-1alpha. Furthermore, there was a direct dose dependent relationship revealing higher IL-1 antagonism of rhIL-1ra at higher concentrations with maximum efficacy at 1000-molar excess concentrations over IL-1alpha. In addition, rhIL-1ra alone did not reveal major modulation of the growth of A 375, but significantly decreased colony formation of HTB 14. We conclude that rhIL-1ra can counteract modulation of clonal growth of human tumor cells by IL-1alpha in vitro. Since our report provides first evidence that the stimulation of clonal tumor cell growth by IL-1alpha can be blocked by rhIL-1ra, this member of the IL-1 cytokine network should be further studied as a possible candidate for experimental cancer treatment.

Abstract
Haematopoietic growth factors such as human granulocyte colony-stimulating factor (G-CSF) have been shown to stimulate in vitro growth of some human solid tumour cell lines. Among these is the human colorectal adenocarcinoma cell line HTB 38. The in vivo relevance of this finding was tested by xenografting HTB 38 cells intracutaneously into athymic nu/nu BALB/c mice. Recombinant human (rh) G-CSF was administered as a subcutaneous bolus twice daily from day 1 to 14 after tumour transplantation at a dose level of 312 mug/kg/day. Serum levels of rhG-CSF were within the range required for the in vitro effect. However, the cytokine caused no significant growth modulation of the tumour in vivo.

Abstract
In the present study we report that recombinant human (rh) interleukin 4 (IL-4) has direct, dose-dependent antiproliferative effects on the human lung cancer cell line CCL 185 in vitro as measured by a human tumor cloning assay (HTCA). The biological response of the tumor cells to rhIL-4 is correlated with expression of specific binding sites for human (h) IL-4 on the cell surface. Furthermore, we have xenotransplanted CCL 185 into BALB/c nu/nu mice. Subsequently, the mice were treated for 17 days with twice 0.5 mg/m2 rhIL-4 or control vehicle subcutaneously per day. Treatment with rhIL-4 yielded a significant inhibition of tumor growth versus control. Histology of the tumors in both groups showed no marked infiltration of the tumors with murine hematopoietic and lymphocytic cells consistent with the species specificity of IL-4. We conclude that rhIL-4 has direct antiproliferative effects on the growth of a human lung tumor cell line in vitro and in vivo which together with its regulatory effects on various effector cell populations makes this cytokine a possible candidate for experimental cancer treatment.
