Abstract
Abstract
In 1996, U.S. Food and Drug Administration regulations mandated the fortification of enriched cereal-grain products with folic acid, thereby emphasizing the need for validated methods for total folates in foods, particularly cereal products. The AOAC Official Methods (944.12, 960.46) currently used for the analysis of folate in foods for compliance purposes are microbiological methods. When the fortification regulations were finalized, no Official AOAC or Approved AACC methods for folate in cereal-grain products were in place. The AOAC Official Method (992.05) for folic acid in infant formula does not incorporate important improvements in the extraction procedure and was not considered suitable for the analysis of folates in foods in general. Amicrobiological assay protocol using a trienzyme extraction procedure was prepared and submitted for comments to 40 laboratories with recognized experience in folate analysis. On the basis of comments, the method was revised to have the conjugase (gamma-glutamyl-carboxy-peptidase) treatment follow a protease treatment, to include the use of cryoprotected inoculum, and to include the spectroscopic standardization of the standard and optional use of microtiter plates. Thirteen laboratories participated in a collaborative study of 10 required and 10 optional cereal-grain products, including flour, bread, cookies, baking mixes, and ready-to-eat breakfast cereals. The majority of the participating laboratories performed the assay by the standard test tube method; others used the microtiter plate modification for endpoint quantitation with equal success. For the required products, the relative standard deviation between laboratories (RSDR) ranged from 7.4 to 21.6% for 8 fortified (or enriched) products compared with expected (Horwitz equation-based) values of 11–20%. RSDR values were higher (22.7–52.9%) for 2 unfortified cereal-grain products. For the optional products, the RSDR ranged from 1.8 to 11.2% for 8 fortified products. RSDR values were higher (27.9–28.7%) for 2 unfortified cereal-grain products. Based on the results of the collaborative study, the microbiological assay with trienzyme extraction is recommended for adoption as Official First Action.

Abstract
OBJECTIVE The Post-Operative Radiation Therapy in Endometrial Carcinoma (PORTEC)-4a trial is a randomized trial for women with high-intermediate risk endometrial cancer (EC), comparing individualized adjuvant treatment based on a molecular-integrated risk profile to standard adjuvant treatment; vaginal brachytherapy. To evaluate patient acceptability and pathology logistics of determining the risk profile, a pilot phase was included in the study. METHODS PORTEC-4a is ongoing and the first 50 patients enrolled were included in the pilot phase. Primary endpoints of the pilot phase were patient acceptance, evaluated by analyzing the screening logs of the participating centers, and logistical feasibility of determination of the risk profile within 2 weeks, evaluated by analyzing the pathology database. RESULTS In the first year, 145 eligible women were informed about the trial at 13 centers, of whom 50 (35%) provided informed consent. Patient accrual ranged from 0 to 57% per center. Most common reasons for not participating were: not willing to participate in any trial (43.2%) and not willing to risk receiving no adjuvant treatment (32.6%). Analysis of the pathology database showed an average time between randomization and determination of the molecular-integrated risk profile of 10.2 days (1-23 days). In 5 of the 32 patients (15.6%), pathology review took >2 weeks. CONCLUSIONS The PORTEC-4a trial design was proven feasible with a satisfactory patient acceptance rate and an optimized workflow of the determination of the molecular-integrated risk profile. PORTEC-4a is the first randomized trial to investigate use of a molecular-integrated risk profile to determine adjuvant treatment in EC.

Abstract
SummaryA considerable inter-individual variation in half-life of infused factor VIII is observed among patients with hemophilia A. The factors contributing to this wide range in factor VIII half-life are not known in detail. We analysed the pharmacokinetics of infused factor VIII in 32 patients with hemophilia A, comprising 20 brothers from 10 families, 3 and 4 brothers from 2 families, and 5 patients from 5 single families, respectively. Multiple linear regression analysis was used to asses the effect of several variables on factor VIII half-life. We found that the pre-infusion von Willebrand factor antigen levels (vWF:Ag) were positively correlated with factor VIII half-life (r = 0.52, p = 0.002), i. e., each variable was associated with about 27% of the variance of the other. In fraternal pairs, familial clustering was significant for AB0 blood group (p < 0.001), but could not be detected for factor VIII half-lives or pre-infusion vWF:Ag levels. vWF:Ag level (p = 0.001) and AB0 blood group (p = 0.003) significantly determined factor VIII half-life, whereas age, length, bodyweight, the presence or absence of a factor VIII gene inversion, and Rhesus phenotype did not. Patients with blood group 0 exhibited a statistically significant shorter factor VIII half-life than patients with blood group A (15.3 versus 19.7 h, respectively) (p = 0.003). Patients with blood group A and 0 differ in respect to the presence of anti-A antibodies in the latter. It is possible that these anti-A antibodies interact with endogenous vWF, thus affecting the half-life time of the factor VIII/vWF complex.

Abstract
BACKGROUND A marginal interaction between sex and the type of alkylating agent was observed for event-free survival in the Euro-EWING99-R1 randomized controlled trial (RCT) comparing cyclophosphamide and ifosfamide in Ewing sarcoma. To further evaluate this interaction, we performed an individual patient data meta-analysis of RCTs assessing cyclophosphamide versus ifosfamide in any type of cancer. METHODS A literature search produced two more eligible RCTs (EICESS92 and IRS-IV). The endpoints were progression-free survival (PFS, main endpoint) and overall survival (OS). The hazard ratios (HRs) of the treatment-by-sex interaction and their 95% confidence interval (95% CI) were assessed using stratified multivariable Cox models. Heterogeneity of the interaction across age categories and trials was explored. We also assessed this interaction for severe acute toxicity using logistic models. RESULTS The meta-analysis comprised 1,528 pediatric and young adult sarcoma patients from three RCTs: Euro-EWING99-R1 (n = 856), EICESS92 (n = 155), and IRS-IV (n = 517). There were 224 PFS events in Euro-EWING99-R1 and 200 in the validation set (EICESS92 + IRS-IV), and 171 and 154 deaths in each dataset, respectively. The estimated treatment-by-sex interaction for PFS in Euro-EWING99-R1 (HR = 1.73, 95% CI = 1.00-3.00) was not replicated in the validation set (HR = 0.97, 95% CI = 0.55-1.72), without heterogeneity across trials (P = 0.62). In the pooled analysis, the treatment-by-sex interaction was not significant (HR = 1.31, 95% CI = 0.89-1.95, P = 0.17), without heterogeneity across age categories (P = 0.88) and trials (P = 0.36). Similar results were observed for OS. No significant treatment-by-sex interaction was observed for leucopenia/neutropenia (P = 0.45), infection (P = 0.64), or renal toxicity (P = 0.20). CONCLUSION Our meta-analysis did not confirm the hypothesis of a treatment-by-sex interaction on efficacy or toxicity outcomes.

Abstract
BACKGROUND In the Netherlands, seclusion is historically the measure of first choice in dealing with aggressive incidents. In 2010, the Mediant Mental Health Trust in Eastern Netherlands introduced a policy prioritising the use of enforced medication to manage aggressive incidents over seclusion. The main goal of the study was to investigate whether prioritising enforced medication over seclusion leads to a change of aggressive incidents and coercive measures. METHODS The study was carried out with data from 2764 patients admitted between 2007 and 2013 to the hospital locations of the Mediant Mental Health Trust in Eastern Netherlands, with a catchment area of 500,000 inhabitants. Seclusion, restraint and enforced medications as well as other coercive measures were gathered systematically. Aggressive incidents were assessed with the SOAS-R. An event sequence analysis was preformed, to assess the whether seclusion, restraint or enforced medication were used or not before or after aggressive incidents. RESULTS Enforced medication use went up by 363% from a very low baseline. There was a marked reduction of overall coercive measures by 44%. Seclusion hours went down by 62%. Aggression against staff or patients was reduced by 40%. CONCLUSIONS When dealing with aggression, prioritising medication significantly reduces other coercive measures and aggression against staff, while within principles of subsidiarity, proportionality and expediency.

Abstract
OBJECTIVE Aim of this study is analysing the pooled results of Intra-Operative Electron beam Radiotherapy (IOERT) containing multimodality treatment of locally recurrent rectal cancer (LRRC) of two major treatment centres. METHODS AND MATERIALS Five hundred sixty five patients with LRRC who underwent multimodality-treatment up to 2010 were studied. The preferred treatment was preoperative chemo-radiotherapy, surgery and IOERT. In uni- and multivariate analyses risk factors for local re-recurrence, distant metastasis free survival, relapse free survival, cancer-specific survival and overall survival were studied. RESULTS Two hundred fifty one patients (44%) underwent a radical (R0) resection. In patients who had no preoperative treatment the R0 resection rate was 26%, and this was 43% and 50% for patients who respectively received preoperative re-(chemo)-irradiation or full-course radiotherapy (p < 0.0001). After uni- and multivariate analysis it was found that all oncologic parameters were influenced by preoperative treatment and radicality of the resection. Patients who were re-irradiated had a similar outcome compared to patients, who were radiotherapy naive and could undergo full-course treatment, except the chance of local re-recurrence was higher for re-irradiated patients. Waiting-time between preoperative radiotherapy and IOERT was inversely correlated with the chance of local re-recurrence, and positively correlated with the chance of a R0 resection. CONCLUSIONS R0 resection is the most important factor influencing oncologic parameters in treatment of LRRC. Preoperative (chemo)-radiotherapy increases the chance of achieving radical resections and improves oncologic outcomes. Short waiting-times between preoperative treatment and IOERT improves the effectiveness of IOERT to reduce the chance of a local re-recurrence.

Abstract
Curative therapies for Ewing sarcoma have been developed within cooperative groups. Consecutive clinical trials have systematically assessed the impact and timing of local therapy and the activity of cytotoxic drugs and their combinations. They have led to an increase of long-term disease-free survival to around 70% in patients with localized disease. Translational research in ES remains an area in which interdisciplinary and international cooperation is essential for future progress. This article reviews current state-of-the art therapy, with a focus on trials performed in Europe, and summarizes novel strategies to further advance both the cure rates and quality of survival.

Abstract
BACKGROUND Since the Dutch Mental Health Act of 1984 came into effect, seclusion has often been used as the measure of choice for dealing with aggressive or dangerous patients. In 2012 the Ministry of Health formulated a policy whereby seclusion was to be phased out, but not replaced by involuntary medication. In 2007, within the framework of the Mental Health Act, the Argus system of registering coercive measures was introduced in order to monitor the reduction in the use of seclusion and involuntary medication. This article describes, in a longitudinal cohort study, the effect of the policy to reduce aggression by replacing seclusion through the use of involuntary medication or other measures. AIM To investigate whether, in the long run, a reduction in the use of seclusion will lead to a proportional increase in the use of involuntary medication, and to assess whether this policy can really be termed 'substitution. METHOD We performed this study by analysing Argus data for the period 2007-2011, relating to 1843 patients being treated by Mediant. ESULTS The changing proportions of seclusion and involuntary medication over time demonstrated that the use of involuntary medication did result in patients being secluded for a shorter period of time. CONCLUSION In the case of dangerous psychiatric patients, medication, administered forcibly when necessary, is preferable to seclusion as far as subsidiarity, proportionality and expediency are concerned. A strategy whereby medication provides appropriate treatment and seclusion is kept within reasonable limits cannot be termed 'substitution'.

Abstract
Osteosarcoma of the cranio-facial structures and skull is rare. In children, only 5.6% of cases are localized in these areas. It is claimed that the mean age at presentation is at least 10-15 years higher than for osteosarcomas in other parts of the body. However these reports are based on data from single institutions or compiled from several registries. It is further claimed that tumours in the mandible and maxilla are less malignant, as based on observations of a better prognosis and lower incidence of metastatic spread as compared with osteosarcomas arising elsewhere. We report all histologically proven cranio-facial osteosarcomas in The Netherlands occurring over a 20-year period, based on the national registration covering all Dutch pathology laboratories (PALGA). The age-corrected incidence of primary osteosarcoma ranged from 0.33 to 0.41 per million across the age ranges. The mandible was the most frequent site of involvement. Only 61% had a high malignant histological grading. Our data indicate that the age-corrected incidence of primary osteosarcomas is similar across all age ranges. In respect to histology, a lower grade of malignancy is more frequent. Maxillary lesions significantly more often have a lower histological grade of malignancy.

Abstract
Children with acute lymphoblastic leukemia (ALL) and high minimal residual disease (MRD) levels after initial chemotherapy have a poor clinical outcome. In this prospective, single arm, Phase 2 trial, 111 Dutch and Australian children aged 1-18 years with newly diagnosed, t(9;22)-negative ALL, were identified among 1041 consecutively enrolled patients as high risk (HR) based on clinical features or high MRD. The HR cohort received the AIEOP-BFM (Associazione Italiana di Ematologia ed Oncologia Pediatrica (Italy)-Berlin-Frankfurt-Münster ALL Study Group) 2000 ALL Protocol I, then three novel HR chemotherapy blocks, followed by allogeneic transplant or chemotherapy. Of the 111 HR patients, 91 began HR treatment blocks, while 79 completed the protocol. There were 3 remission failures, 12 relapses, 7 toxic deaths in remission and 10 patients who changed protocol due to toxicity or clinician/parent preference. For the 111 HR patients, 5-year event-free survival (EFS) was 66.8% (±5.5) and overall survival (OS) was 75.6% (±4.3). The 30 patients treated as HR solely on the basis of high MRD levels had a 5-year EFS of 63% (±9.4%). All patients experienced grade 3 or 4 toxicities during HR block therapy. Although cure rates were improved compared with previous studies, high treatment toxicity suggested that novel agents are needed to achieve further improvement.

Abstract
BACKGROUND We report on the treatment of children and adolescents with acute lymphoblastic leukemia (ALL) in first relapse. The protocol focused on: (1) Intensive chemotherapy preceding allogeneic stem cell transplantation (SCT) in early bone marrow relapse; (2) Rotational chemotherapy in late relapse, without donor; (3) Postponement of cerebro-spinal irradiation in late isolated CNS relapse; and (4) Treatment in very late bone marrow relapse with chemotherapy only. METHODS From January 1999 until July 2006 all 158 Dutch pediatric patients with ALL in first relapse were recorded. Ninety-nine patients were eligible; 54 patients with early and 45 with late relapse. Eighteen patients had an isolated extra-medullary relapse; 69 patients had bone marrow involvement only. RESULTS Five-years EFS rates for early and late relapses were 12% and 35%, respectively. For early relapses 5 years EFSs were 25% for patients transplanted; 0% for non-transplanted patients. For late relapses 5 years EFS was 64% for patients treated with chemotherapy only, and 16% for transplanted patients. For very late relapses EFS was 58%. CONCLUSIONS Our data suggest the superiority of SCT for early relapse patients. For late relapses a better outcome is achieved with chemotherapy only using the rotational chemotherapy scheme. The most important factor for survival was interval between first CR and occurrence of the first relapse.

Abstract
SETTING Two districts of the Free State Province in South Africa. OBJECTIVE To determine the predictors of human immunodeficiency virus (HIV) test uptake by tuberculosis (TB) patients. DESIGN A cross-sectional survey was conducted among 600 TB patients in 61 primary health care facilities. Probability proportional-to-size sampling was used to determine the number of patients recruited at each facility. Structured exit interviews were conducted with convenience samples of patients at these facilities. Descriptive and logistic regression analyses were performed on the data. RESULTS The average age of the recruited TB patients was 38.4 years. The majority were female (n = 310, 51.7%), unmarried (n = 439, 73.3%), unemployed (n = 513, 85.5%) and had undertaken HIV testing (n = 405, 67.5%). In multivariate analysis, having received information on the relationship between TB and HIV (OR 5.4, 95%CI 3.1-9.5) was the strongest predictor of HIV test uptake among unmarried patients. Other associated factors included knowing/having lost someone ill with HIV/AIDS (acquired immune-deficiency syndrome; OR 3.6, 95%CI 2.2-5.8), female sex (OR 2.3, 95%CI 1.4-3.7), unemployment (OR 2.2, 95%CI 1.2-4.1) and undergoing retreatment for TB (OR 2.0, 95%CI 1.2-3.2). CONCLUSION HIV test scale-up efforts should aim to increase TB patients' awareness of the relationship between TB and HIV/AIDS and consider the impact of socio-demographic factors.

Abstract
The Paediatric Regulation has been in force in the EU since 1 July 2007. This has changed the procedure for obtaining marketing authorisation of medicines in Europe so that new medications can be adapted safely for use in children. Additional provisions have been made for the use of authorised and generic medications in children. Research is being stimulated through subsidies and the extension of exclusive distribution rights for manufacturers. Other initiatives are aimed at making existing data on the use of medications in children accessible. Many of these tasks are the responsibility of a special European paediatric committee, which also assesses proposals for research on medication use in children.

Abstract
Many studies confirm the clinical interest of photodynamic diagnostics (PDD) in non-muscle invasive bladder cancer management. PDD or fluorescence cystoscopy is not only of great value in occult urothelial cancer detection, but may have a positive impact on disease-free survival and prognosis. Yet, its specificity is found to be highly variable between studies mainly in relation to different disease profiles. New imaging techniques aimed at enhancing visualization to assess the bladder wall are under development.

Abstract
INTRODUCTION Childhood cancer survivors are known to be at increased risk for second malignancies. PATIENTS AND METHODS The risk of second malignancies was assessed in 1368 5-year survivors of childhood cancer treated in the Emma Children's Hospital AMC in Amsterdam. The median follow-up time was 16.8 years. RESULTS Sixty two malignancies were observed against 5.4 expected, yielding a standardised incidence ratio (SIR) of 11.2 (95% confidence interval: 8.53-14.4; absolute excess risk: 3.2 per 1000 person-years). New observations were the strongly increased risks of meningiomas (SIR=40) and basal cell carcinomas (SIR=9). Patients whose treatment involved radiotherapy had a 2-fold increased second cancer risk compared to patients with chemotherapy alone. DISCUSSION The relative risk of second malignancies does not decrease till at least 30 years of follow-up. With aging of the survivor cohort this results in a strong increase of the AER, due to the rising background risk of cancer with age.

Abstract
OBJECTIVE To determine the effect of folic acid, vitamin B(6) and B(12) fortified spreads on the blood concentrations of these vitamins and homocysteine. DESIGN AND SETTING A 6-week randomized, double-blinded, placebo-controlled, parallel trial carried out in a clinical research center. SUBJECTS One hundred and fifty healthy volunteers (50% males). INTERVENTIONS For 6 weeks, the subjects consumed the test spreads (20 g/day): containing per 20 g (1) 200 microg folic acid, 2 microg vitamin B(12) and 1 mg vitamin B(6), or (2) 400 microg folic acid, 2 microg vitamin B(12) and 1 mg vitamin B(6) or (3) no B-vitamins (control spread). RESULTS The B-vitamin status increased on using the test spreads, with the largest effect on the serum folate concentration: 48% in men and 58% in women on spread 1 and 92 and 146%, respectively, on spread 2 (P-values all <0.05). The plasma homocysteine decreased in the groups treated with the fortified spreads as compared to the control group. Average decreases were for males: 0.7+/-1.5 micromol/l (6.8%) on spread 1 and 1.7+/-1.7 micromol/l (17.6%) on spread 2 and for females: 1.4+/-1.2 micromol/l (14.2%) and 2.4+/-2.0 micromol/l (23.3%), respectively (P-values all <0.05). CONCLUSIONS Consumption of a spread fortified with folic acid, vitamin B(6) and vitamin B(12) for 6 weeks significantly increases the blood concentrations of these vitamins and significantly decreases the plasma concentration of homocysteine. Fortified staple foods like spreads can contribute to the lowering of homocysteine concentrations.

Abstract
BACKGROUND In the near future, a substantial proportion of adults will be childhood cancer survivors. The cryopreservation and transplantation of spermatogonial stem cells (SSCs) is currently successful in animals; application in humans seems likely in the near future. Cryopreserving SSCs might become an important issue in childhood cancer. Because this might require testicular biopsies or hemicastration, parental desire/acceptability for SSC collection was enquired for. METHODS Three hundred eighteen parents of boys surviving at least 2 years after the diagnosis of cancer were asked about collecting SSCs by biopsy or hemicastration and collecting sperm by masturbation or electrostimulation. Opinions were assessed as if at the time of diagnosis and at the present time. RESULTS Sixty-three per cent of parents responded. At diagnosis, SSC collection by means of biopsy was approved by 61%, hemicastration by 33% and collecting sperm by 70% (P < 0.013). The acceptability of performing hemicastration was significantly lower than all other forms of SSC/sperm collection. No differences were observed between parents' present opinion and opinion at diagnosis. No differences related to treatment intensity, presumed negative fertility effects and pubertal state were found. CONCLUSIONS Infertility is a major topic for parents. For prepubertal boys, the collection of SSCs might be a great relief in respect of the fertility issue. Collecting SSCs by biopsy is desired and accepted by the majority of parents; hemicastration is accepted by one-third of parents. The translation of SSC cryopreservation and transplantation from animal models to humans is eagerly awaited.

Abstract
Central giant cell granuloma (CGCG) is a benign lesion of the jaws with a sometimes locally aggressive behaviour. The most common therapy is surgical curettage which has a high recurrence rate, especially in lesions with aggressive signs and symptoms (i.e. pain, paresthesia, root-resorption and rapid growth). Alternative therapies such as interferon alpha (INFalpha) or calcitonin are described in the literature. In this study 2 patients with an aggressive CGCG are presented who were treated with INF mono-therapy. INF mono-therapy was capable of terminating the rapid growth of the lesion in both patients and induced a partial reduction. Total resolution, however, was not obtained and alternative treatment is still necessary.

Abstract
The successful therapeutic use of calcitonin in patients with a central giant cell granuloma has been shown in several case reports. In a prospective, randomized, double-blinded, placebo-controlled clinical trial, 14 patients with a histologically confirmed central giant cell granuloma and normal calcium and parathyroid hormone serum levels were studied over 2 years. Patients were treated with intranasally administered salmon calcitonin (200 IU/day) or a placebo once a day. The placebo-controlled period was 3 months, after which all patients were treated with calcitonin for 1 year. Treatment response was assessed at the end of the placebo-controlled study phase (3 months), at the end of therapy (15 months' timepoint with patients being on calcitonin treatment for either 12 or 15 months) and at 6 months' follow-up. The chi(2)-test was used to compare the proportion of patients with a tumour reduction >/=10% of the pretreatment measurement between the 2 populations at the 3 timepoints: no differences were observed between the placebo group and the calcitonin group. At the 6-month follow-up timepoint, tumour volume had decreased by >/=10% in a total of 7 patients with a 37.9% (95% CI 31.3-44.5%) mean volume reduction in this subgroup. Complete remission was not observed.

Abstract
OBJECTIVE The aim of this study was to investigate whether milk fortified with folic acid enhances the folate status of humans and whether the presence of folate-binding proteins (FBP) in pasteurised milk affects the bioavailability of folic acid from fortified milk. In untreated and pasteurised milk, folate occurs bound to FBP, while FBP is (partly) denatured in ultra-high-temperature (UHT)-treated milk. The effect of FBP on folate bioavailability is still unclear. DESIGN, SUBJECTS AND SETTING Healthy, free-living subjects (n=69) aged 18-49 y participated in a 4-week double-blind, placebo-controlled dietary intervention study. INTERVENTION In addition to a fully controlled diet, the subjects consumed each day 500 ml of pasteurised or UHT milk, either fortified or not with 200 mug folic acid. RESULTS Consumption of fortified milk increased folate concentrations in serum and in red blood cells (RBC) by 6.6-7.0 nmol/l (P<0.001) and 32-36 nmol/l (P<0.01), respectively. Similarly, plasma homocysteine concentrations were lowered 0.88-0.89 micromol/l (P=0.001) in subjects who consumed fortified milk. The bioavailability of folic acid from pasteurised milk relative to that of folic acid from UHT milk was 74-94% (NS), depending on the parameter used. CONCLUSIONS Milk fortified to supply an additional 200 microg of folic acid/s substantially increased folate status, and decreased plasma total homocysteine concentrations in young, healthy subjects. Milk is therefore a suitable matrix for fortification to enhance the folate status in humans. No significant effect of endogenous FBP was found on the bioavailability of folic acid from milk.

Abstract
In 1996, U.S. Food and Drug Administration regulations mandated the fortification of enriched cereal-grain products with folic acid, thereby emphasizing the need for validated methods for total folates in foods, particularly cereal products. The AOAC Official Methods (944.12, 960.46) currently used for the analysis of folate in foods for compliance purposes are microbiological methods. When the fortification regulations were finalized, no Official AOAC or Approved AACC methods for folate in cereal-grain products were in place. The AOAC Official Method (992.05) for folic acid in infant formula does not incorporate important improvements in the extraction procedure and was not considered suitable for the analysis of folates in foods in general. A microbiological assay protocol using a trienzyme extraction procedure was prepared and submitted for comments to 40 laboratories with recognized experience in folate analysis. On the basis of comments, the method was revised to have the conjugase (gamma-glutamyl-carboxy-peptidase) treatment follow a protease treatment, to include the use of cryoprotected inoculum, and to include the spectroscopic standardization of the standard and optional use of microtiter plates. Thirteen laboratories participated in a collaborative study of 10 required and 10 optional cereal-grain products, including flour, bread, cookies, baking mixes, and ready-to-eat breakfast cereals. The majority of the participating laboratories performed the assay by the standard test tube method; others used the microtiter plate modification for endpoint quantitation with equal success. For the required products, the relative standard deviation between laboratories (RSD(R)) ranged from 7.4 to 21.6% for 8 fortified (or enriched) products compared with expected (Horwitz equation-based) values of 11-20%. RSD(R) values were higher (22.7-52.9%) for 2 unfortified cereal-grain products. For the optional products, the RSD(R) ranged from 1.8 to 11.2% for 8 fortified products. RSD(R) values were higher (27.9-28.7%) for 2 unfortified cereal-grain products. Based on the results of the collaborative study, the microbiological assay with trienzyme extraction is recommended for adoption as Official First Action.

Abstract
BACKGROUND Children treated for Hodgkin disease are at risk for gonadal damage. Since most children were treated with radiotherapy (RT) in combination with chemotherapy, the presumed detrimental effect of MOPP (mustine, vincristine, procarbazine, and prednisone) (in contrast to schemes with less or without alkylating agents) could not be discerned completely from the effects of RT. PROCEDURES Children with Hodgkins disease treated without RT were included in sequential protocols containing six courses of MOPP (n = 24), six courses of ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) (n = 17), or three courses of MOPP/ABVD (n = 35). Of these 76 patients, 48, who had completed treatment and had reached puberty, were investigated for gonadal damage. RESULTS Of the male patients, 81% of MOPP treated patients had increased follicular stimulating hormone (FSH) values, in 23% luteinizing hormone (LH) values were abnormal. In ABVD treated patients, no elevated levels of FSH or LH were noted. In 30% of patients treated with MOPP/ABVD, FSH values were abnormal, but no abnormal LH values were found. Median testicular volume per group decreased in relation to a higher number of MOPP courses. Sperm analysis revealed azoospermia in nearly all MOPP treated patients. In ABVD and MOPP/ABVD treated patients both oligospermia and azoospermia were noted. The number of sperm samples were too less to make any sound conclusions. Menarche occurred in all females, however in some at a relatively later age. One female patient treated with MOPP/ABVD had a normal pregnancy. CONCLUSIONS Limitation of MOPP therapy to three courses, in children treated without any RT, results in less gonadal damage as compared with six MOPP courses. From our data, MOPP damages Sertoli cells and may also damage Leydig cells as suggested by the higher LH values in conjunction with normal testosterone levels.

Abstract
We have previously synthesised a number of novel head-to-head bis-benzimidazole derivatives that are structurally related to the fluorochrome, Hoechst 33258, and which possess strong affinity for A:T sites in the minor groove of duplex DNA. Initial studies revealed these compounds to exhibit potent antiproliferative activity against a range of ovarian cell lines and to inhibit transcription in an in vitro setting. In this study, we have examined their cellular behaviour in detail and have shown that two of these compounds (ABA13 and ABA833) potently inhibit the proliferation of a range of human tumour cell lines, and show some specificity towards breast carcinoma cell lines. In most of the cell lines investigated, ABA833 was the more potent of the two compounds. Flow cytometric analysis revealed that ABA13 and ABA833 (50-500 nM) induced an S phase block and increased the pre-G1 population in MCF-7 and MDA 468 human breast cancer cells. An increase in the pre-G1 population of RKO colon carcinoma cells was seen only at 500 nM with ABA833, reflecting the reduced sensitivity of this cell line to the bis-benzimidazoles in comparison to the breast cancer cell lines. Mechanistic studies revealed that neither ABA13 or ABA833 act as topoisomerase I (topo I) or topoisomerase II (topo II) poisons in plasmid or kinetoplast DNA (kDNA) relaxation assays, but both compounds do inhibit the catalytic activity of these enzymes. Drug uptake studies showed that reduced sensitivity of MCF-7adr and RKO cells compared with MCF-7 to both ABA13 and ABA833 correlated with a markedly reduced intracellular drug accumulation.

Abstract
A balanced diet based on the Guidelines of the Netherlands Nutrition Centre provides a suitable basis for the maintenance of good health. However, there are a number of situations where supplementation with vitamins is clearly indicated. These include infants (vitamin A, D and K), young children, and pregnant and lactating women (vitamin D), future expectant mothers (folic acid) and the elderly (vitamin D). If doubts exist about a sufficient vitamin intake via the regular diet, a daily supplement supplying all vitamins at the level of the recommended daily allowance (RDA) is considered to be a responsible and safe choice. Epidemiological research indicates that the incidence of certain diseases is lower if the intake of vitamins is significantly higher than the RDA. However to date, targeted intervention studies have provided little unequivocal evidence to support this argument. For certain vitamins (A, D, folic acid, B6, nicotinic acid and beta-carotene) excessive intakes are associated with a health risk or clear toxicity. In the case of vitamin B6, nicotinic acid, folic acid and beta-carotene this risk is mainly limited to the use of high-dose supplements.

Abstract
GOALS Hyperuricaemia (HU) and tumour lysis syndrome (TLS) are complications of acute myeloid/lymphoid leukaemia (AML/ALL) and non-Hodgkin lymphoma (NHL) leading to increased morbidity and mortality. The objective was to assess incremental cost-effectiveness ratios (ICER) of preventing/treating HU and TLS with recombinant urate oxidase, rasburicase (Fasturtec/Elitek). PATIENTS AND METHODS Incidence and costs of HU and TLS were based on a multi-country chart review. Life expectancy at the time of diagnosis was based on published survival rates and age at diagnosis. Reductions of HU/TLS following treatment with rasburicase were based on clinical trial data. RESULTS Prevention with rasburicase appears highly cost-effective in children (ICER between Eur 425 and Eur 3054 per life-year saved, LYS). In adults, prevention is more cost-effective in NHL and ALL (maximum ICER of Eur 41383 and Eur 32126 per LYS). Treatment of established HU/TLS with rasburicase is cost-saving in children and highly cost-effective in adults. The results are robust in children. In adults, the prevention strategy appears sensitive to the risk of HU/TLS. CONCLUSIONS In conclusion, rasburicase, in addition to the demonstrated clinical benefit, is an economically attractive new option in the treatment of HU, both in adults and children. In prevention the drug has an attractive economic profile in children, and is cost-effective in adults with ALL and NHL.

Abstract
A 13-year-old girl and a 3-year-old boy presented with the clinical symptoms of nephrotic syndrome. Both patients developed a nodular mass in the cervical region, which appeared to be due to Hodgkin's disease. The renal disease was a paraneoplastic phenomenon of Hodgkin's disease. Chemotherapy given for Hodgkin's disease also cured the nephrotic syndrome. A few years later one of the patients experienced a recurrent episode of nephrotic syndrome in conjunction with a recurrence of Hodgkin's disease but this was once again treated successfully. Nephrotic syndrome is a known but rare paraneoplastic syndrome accompanying Hodgkin's disease. It is thought that T cell dysfunction leads to a secretion of cytokines which alters the permeability of the glomerular basement membrane. This dysfunction is not only apparent during the period of active disease and this could clarify why paraneoplastic syndrome can exist or recur outside the period in which the malignancy is overt. The clear recognition of a paraneoplastic syndrome is important, as it is often only necessary to treat the malignancy.

Abstract
Prospective studies in children with B-precursor acute lymphoblastic leukaemia (ALL) have shown that polymerase chain reaction (PCR)-based detection of minimal residual disease (MRD) using immunoglobin (Ig) and T-cell receptor (TCR) gene rearrangements as targets can be used to identify patients with a high relapse risk. The disadvantage of this approach is that for each patient preferably two different targets have to be identified. The t(12;21)(p13;q22) with the TEL-AML1 fusion gene is present in approximately 25% of children with B-precursor ALL. In these patients, sensitive reverse transcription (RT)-PCR analysis of the TEL-AML1 fusion transcript might be a more simple and less laborious alternative approach. However, it is unknown how stable the mRNA is and whether the number of transcripts per leukaemic cell remains constant during follow-up. We investigated whether the MRD results obtained using RT-PCR of TEL-AML1 transcripts correlated with the clinically validated genomic PCR for Ig and TCR gene rearrangements. Therefore, we used real-time quantitative (RQ)-PCR analysis for both types of targets and assessed the MRD levels in 36 follow-up bone marrow samples (obtained during the first 1.5 years after diagnosis) from 13 patients with B-precursor ALL. In 34/36 bone marrow samples the Ig/TCR RQ-PCR and TEL-AML1 RQ-PCR revealed equal levels of MRD and these results had a strong correlation (P < 0.0001, R2 = 0.84). Therefore, we conclude that the TEL-AML1 RQ-PCR can, in principle, replace Ig/TCR RQ-PCR in B-precursor ALL with t(12;21).

Abstract
The objectives of the present study were to compare the bioavailability of vitamin A from liver paste and from a vitamin A supplement at three nutritionally relevant levels of intake, and to estimate levels of "safe" intake based on concentrations of retinoic acid and its metabolites in plasma after a single dose of vitamin A from liver paste. Women (n = 35; 19-47 y of age) consumed 3.0, 7.5 or 15 mg vitamin A as liver paste or as a vitamin A supplement with a test meal in a randomized design, with a combined crossover (two sources) and parallel approach (three dosages). Retinyl esters and retinoic acid (RA) metabolites were quantified in blood samples at 2-24 h after dosing. The areas under the time-response curves (AUC) were calculated to evaluate responses in plasma vitamin A after intake of liver paste and the vitamin A supplements. For retinyl esters, the AUC was significantly affected by the dosage, but not by the source. The formation of 13-cis-RA, 13-cis-4-oxo-RA, and to a lesser extent all-trans-RA was significantly higher after consumption of liver paste compared with the supplement, especially at higher dosages. Long-term baseline concentrations of retinol were not affected by a single intake of vitamin A. In conclusion, the bioavailability of vitamin A from single doses of liver paste and a vitamin A supplement does not differ, but the plasma concentrations of RA metabolites are higher after intake of liver paste. Thus, pregnant women should indeed limit the intake of vitamin A from liver products.

Abstract
The 8p11 myeloproliferative syndrome (EMS) is associated with three translocations, t(8;13)(p11;q12), t(8;9)(p11;q33), and t(6;8)(q27;p11), that fuse unrelated genes (ZNF198, CEP110, and FOP, respectively) to the entire tyrosine kinase domain of FGFR1. In all cases thus far examined (n = 10), the t(8;13) results in an identical mRNA fusion between ZNF198 exon 17 and FGFR1 exon 9. To determine if consistent fusions are also seen in the variant translocations, we performed RT-PCR on four cases and sequenced the products. For two patients with a t(8;9), we found that CEP110 exon 15 was fused to FGFR1 exon 9. For two patients with a t(6;8), we found that FOP exon 5 (n = 1) or exon 7 (n = 1) was fused to FGFR1 exon 9. To determine if FGFR1 might be involved in other myeloid disorders with translocations of 8p, we developed a two-color FISH assay using two differentially labeled PAC clones that flank FGFR1. Disruption of this gene was indicated in a patient with a t(8;17)(p11;q25) and Ph-negative chronic myeloid leukemia in association with systemic malignant mast cell disease, a patient with acute myeloid leukemia with a t(8;11)(p11;p15), and two cases with T-cell lymphoma, myeloproliferative disorder, and marrow eosinophilia with a t(8;12)(p11;q15) and ins(12;8)(p11;p11p21), respectively. For the patient with the t(8;11), the chromosome 11 breakpoint was determined to be in the vicinity of NUP98. We conclude that 1) all mRNA fusions in EMS result in splicing to FGFR1 exon 9 but breakpoints in FOP are variable, 2) two-color FISH can identify patients with EMS, and 3) the t(8;17)(p11;q25), t(8;11)(p11;p15), t(8;12)(p11;q15), and ins(12;8)(p11;p11p21) are novel karyotypic changes that most likely involve FGFR1.

Abstract
OBJECTIVE To evaluate the effect of fruit and vegetables consumption on markers of risk for cardiovascular disease. DESIGN Randomised, diet controlled, parallel study. SUBJECTS Forty-eight apparently healthy (40--60 y) volunteers with a low usual consumption of fruit and vegetables. Forty-seven of them completed the study. INTERVENTIONS During 4 weeks 24 volunteers consumed a standardised meal, consisting of 500 g/day fruit and vegetables and 200 ml/day fruit juice ('high' group) and 23 volunteers consumed 100 g/day fruit and vegetables ('low' group) with an energy and fat controlled diet. RESULTS Final total cholesterol was 0.2 (95% CI -0.5--0.03) mmol/l lower in the high group than in the low group (P>0.05). Final fibrinogen and systolic blood pressure were 0.1 (-0.1--0.4) g/l and 2.8 (-2.6--8.1) mmHg higher in the high group than in the low group (P>0.05), respectively. Also, other final serum lipid concentrations, diastolic blood pressure and other haemostatic factors did not differ between both groups. CONCLUSIONS This was a small randomised well-controlled dietary intervention trial of short duration with a considerable contrast in fruit and vegetable consumption. No effects on serum lipids, blood pressure and haemostatic variables were observed.

Abstract
There is increasing interest in the involvement of transcription factors, such as of the transcription factor NF-kappaB (nuclear factor-kappaB), in the pathogenesis of various diseases. NF-kappaB is involved in the control of the transcription of a variety of cellular genes that regulate the inflammatory response by the production of cytokines, chemokines, cell adhesion molecules and acute phase proteins. The involvement of NF-kappaB is especially of interest as it is activated by oxidative stress and its activation can be modulated by antioxidant compounds. The activation of NF-kappaB can be determined by the electromobility shift assay (EMSA) with a NF-kappaB binding-site-specific probe. EMSA can also be used on human mononuclear cells isolated from peripheral blood, which could make the assay applicable for clinical trials. The critical steps of the EMSA are discussed, addressing some pitfalls of the assay. The procedure that can be used to express NF-kappaB activity in human subjects is evaluated. This offers the possibility to use NF-kappaB as a functional biomarker of oxidative stress as illustrated by several examples of in vitro and in vivo studies.

Abstract
The potential benefits of a high fruit and vegetable intake on the antioxidant status and on relevant biomarkers of oxidative damage to lipids, proteins and DNA and on (functional) markers of oxidative stress were evaluated. A randomized, free living, open placebo-controlled cross-over trial of 3 wk, with a 2-wk washout period between treatments, was performed in a group of 22 male smokers with a relatively low vegetable and fruit intake using a vegetable burger and fruit drink. The vegetable burger and fruit drink increased serum levels of vitamin C, alpha-carotene, beta-carotene, beta-cryptoxanthin and zeaxanthin and plasma total antioxidant capacity. However, no effects were demonstrated on any marker of oxidative damage to lipids (malondialdehyde F(2)-isoprostane) proteins (carbonyls) and DNA (Comet assay) and (functional) markers of oxidative stress (reduced/oxidized glutathione ratio, glutathione-S-transferase alpha, glutathione-S-transferase pi and nuclear transcription factor-kappaB). Apparently, these increased levels of antioxidants in serum were not sufficiently high to show beneficial changes with the selected biomarkers. Alternatively, oxidative stress in male smokers with a relatively low fruit and vegetable intake might have been still too low to demonstrate a beneficial effect of antioxidants.
