Abstract
Background The immune pathogenesis underlying the diverse clinical course of COVID-19 is poorly understood. Currently, there is an unmet need in daily clinical practice for early biomarkers and improved risk stratification tools to help identify and monitor COVID-19 patients at risk of severe disease. Methods We performed longitudinal assessment of stimulated immune responses in 30 patients hospitalized with COVID-19. We used the TruCulture whole-blood ligand-stimulation assay applying standardized stimuli to activate distinct immune pathways, allowing quantification of cytokine responses. We further characterized immune cell subsets by flow cytometry and used this deep immunophenotyping data to map the course of clinical disease within and between patients. Results Here we demonstrate impairments in innate immune response pathways at time of COVID-19 hospitalization that are associated with the development of severe disease. We show that these impairments are transient in those discharged from hospital, as illustrated by functional and cellular immune reconstitution. Specifically, we identify lower levels of LPS-stimulated IL-1β, and R848-stimulated IL-12 and IL-17A, at hospital admission to be significantly associated with increasing COVID-19 disease severity during hospitalization. Furthermore, we propose a stimulated immune response signature for predicting risk of developing severe or critical COVID-19 disease at time of hospitalization, to validate in larger cohorts. Conclusions We identify early impairments in innate immune responses that are associated with subsequent COVID-19 disease severity. Our findings provide basis for early identification of patients at risk of severe disease which may have significant implications for the early management of patients hospitalized with COVID-19.

Abstract
We investigated trends of survival in a population-based cohort study of all 181 adults who received HCT for ALL in Denmark between 2000-2019. Patients had a median (min-max) age of 36 (18-74) years at HCT and were followed for a median of eight years. Overall survival (OS) improved over time with an estimated 2-year OS of 49% (CI 27-66%) in year 2000 versus 77% (CI 59-88%) in year 2019. More patients achieved cure over time (OR for cure per year 1.07, CI 1.00-1.15), while the rate of death in non-cured patients remained stable (HR of excess mortality per year 0.99, CI 0.93-1.06). Relapse decreased over time (HR 0.92 per year, CI 0.87-0.98), whereas non-relapse mortality did not change notably (HR 0.98 per year, CI 0.93-1.04). In conclusion, survival after HCT in adults with ALL has improved over the past two decades, primarily due to more patients achieving cure.

Abstract
Objectives The curative effect of allogeneic haematopoietic stem cell transplantation (HSCT) for acute leukaemia is due in part to the donor T cell–mediated graft‐versus‐leukaemia immune reaction (GvL). Several studies have suggested that donor CD25+CD4+Foxp3+regulator T cells (Tregs) may decrease graft‐versus‐host disease (GvHD) without abrogating GVL. This notion may need modification in acute lymphoblastic leukaemia (ALL). Methods Foxp3 mRNA level was measured by qPCR in preharvest donor blood CD4+ T cells. The study comprised 45 patients with ALL in 1st or 2nd CR who received myeloablative HSCT using T‐replete bone marrow grafts. Results Relapse occurred in 17 patients median 363 days after HSCT. The relapse risk was estimated by Cox univariate and multivariate proportional hazard regression. The proportionality assumption was met by analysing the preharvest donor Foxp3 mRNA level as a time‐dependent covariate. Early relapse was not modified by the Foxp3 mRNA level. However, a higher Foxp3 mRNA level was associated with a significantly increased relapse risk after day 363 after transplantation, compatible with inhibition of GvL. In contrast, a higher preharvest donor CD4+ T‐cell concentration was associated with reduced relapse risk. Conclusion A higher preharvest donor Foxp3 mRNA level may be predictive of late ALL relapse after HSCT.

Abstract
BACKGROUND Despite increased knowledge about genetic aberrations in pediatric T-cell acute lymphoblastic leukemia (T-ALL), no clinically feasible treatment-stratifying marker exists at diagnosis. Instead patients are enrolled in intensive induction therapies with substantial side effects. In modern protocols, therapy response is monitored by minimal residual disease (MRD) analysis and used for postinduction risk group stratification. DNA methylation profiling is a candidate for subtype discrimination at diagnosis and we investigated its role as a prognostic marker in pediatric T-ALL. PROCEDURE Sixty-five diagnostic T-ALL samples from Nordic pediatric patients treated according to the Nordic Society of Pediatric Hematology and Oncology ALL 2008 (NOPHO ALL 2008) protocol were analyzed by HumMeth450K genome wide DNA methylation arrays. Methylation status was analyzed in relation to clinical data and early T-cell precursor (ETP) phenotype. RESULTS Two distinct CpG island methylator phenotype (CIMP) groups were identified. Patients with a CIMP-negative profile had an inferior response to treatment compared to CIMP-positive patients (3-year cumulative incidence of relapse (CIR3y ) rate: 29% vs. 6%, P = 0.01). Most importantly, CIMP classification at diagnosis allowed subgrouping of high-risk T-ALL patients (MRD ≥0.1% at day 29) into two groups with significant differences in outcome (CIR3y rates: CIMP negative 50% vs. CIMP positive 12%; P = 0.02). These groups did not differ regarding ETP phenotype, but the CIMP-negative group was younger (P = 0.02) and had higher white blood cell count at diagnosis (P = 0.004) compared with the CIMP-positive group. CONCLUSIONS CIMP classification at diagnosis in combination with MRD during induction therapy is a strong candidate for further risk classification and could confer important information in treatment decision making.

Abstract
Childhood acute lymphoblastic leukemia survival approaches 90%. New strategies are needed to identify the 10-15% who evade cure. We applied targeted, sequencing-based genotyping of 25 000 to 34 000 preselected potentially clinically relevant single-nucleotide polymorphisms (SNPs) to identify host genome profiles associated with relapse risk in 352 patients from the Nordic ALL92/2000 protocols and 426 patients from the German Berlin-Frankfurt-Munster (BFM) ALL2000 protocol. Patients were enrolled between 1992 and 2008 (median follow-up: 7.6 years). Eleven cross-validated SNPs were significantly associated with risk of relapse across protocols. SNP and biologic pathway level analyses associated relapse risk with leukemia aggressiveness, glucocorticosteroid pharmacology/response and drug transport/metabolism pathways. Classification and regression tree analysis identified three distinct risk groups defined by end of induction residual leukemia, white blood cell count and variants in myeloperoxidase (MPO), estrogen receptor 1 (ESR1), lamin B1 (LMNB1) and matrix metalloproteinase-7 (MMP7) genes, ATP-binding cassette transporters and glucocorticosteroid transcription regulation pathways. Relapse rates ranged from 4% (95% confidence interval (CI): 1.6-6.3%) for the best group (72% of patients) to 76% (95% CI: 41-90%) for the worst group (5% of patients, P<0.001). Validation of these findings and similar approaches to identify SNPs associated with toxicities may allow future individualized relapse and toxicity risk-based treatments adaptation.

Abstract
Interleukin-12 receptor deficiency is a well-described cause of human susceptibility to infection with low-virulent mycobacteria and Salmonella species. We identified a male patient presenting in his late forties with severe gastroenteropathy because of outbred infestation by a previously unknown mycobacterium. In addition to selective IgA deficiency, the patient was found to carry a not previously described R283X homozygous mutation in his IL12RΒ1 gene. Two of his sisters, a brother, and his four children were healthy, heterozygous carriers of the mutation. In this patient, the combination of two deficiencies could promote illness. Even though the IgA deficiency in itself does not predispose to mycobacterial disease, the lack of secreted IgA may have disturbed the intestinal homoeostasis and increased the susceptibility to the low-virulent mycobacterium that the patient was not able to clear because of his IL12R deficiency. Antimycobacterial chemotherapy and interferon-γ treatment for 2 years significantly improved his condition. This is the first description of IL12RΒ1 deficiency combined with another immunodeficiency, and we suggest that combinatory defects may circumvent the otherwise low penetrance of IL12RB1 deficiency.

Abstract
REACH requests the exploration of alternative strategies for hazard identification before resorting to (in vivo) testing. Here, we combined read-across as non-testing strategy with a tiered exposure assessment for the risk characterisation of 1-methoxypropan-2-ol (PGME) as a representative for phase-in substances to be registered under REACH. Read-across from the selected source substances provided data which were comparable with experimental data available for target substance PGME, resulting in a realistic starting point for both qualitative and quantitative risk assessment. Greater variability was observed in the exposure estimates from a first Tier model (ECETOC TRA) or less conservative further Tier models (Stoffenmanager; RISKOFDERM), when these results were compared with results from a data-rich approach using measured data. When safe use of chemicals cannot be demonstrated with these approaches, refinement can be introduced in the estimation of hazard and exposure, or both. In view of the variability associated with exposure modeling, it may often add more value to invest in realistic exposure data than in toxicity studies, apart from animal welfare considerations.

Abstract
Low levels of leukemia cells in the bone marrow, minimal residual disease (MRD), are considered to be a powerful indicator of treatment response in acute lymphatic leukemia (ALL). A Nordic quality assurance program, aimed on standardization of the flow cytometry MRD analysis, has been established before implementation of MRD at cutoff level 10 as one of stratifying parameters in next Nordic Society of Pediatric Hematology and Oncology (NOPHO) treatment program for ALL. In 4 quality control (QC) rounds 15 laboratories determined the MRD levels in 48 follow-up samples from 12 ALL patients treated according to NOPHO 2000. Analysis procedures were standardized. For each QC round a compact disc containing data in list-mode files was sent out and results were submitted to a central laboratory. At cutoff level 10, which will be applied for clinical decisions, laboratories obtained a high concordance (91.6%). If cutoff level 10 was applied, the concordance would be lower (85.3%). The continuing standardization resulted in better concordance in QC3 and QC4 compared with QC1 and QC2. The concordance was higher in precursor B as compared with T-cell ALL. We conclude that after standardization, flow cytometry MRD detection can be reliably applied in international, multicenter treatment protocols.

Abstract
Defects of memory B cells and of somatic hypermutation (SHM) are involved in the pathogenesis of common variable immunodeficiency (CVID). Here we report for the first time a systematic study of the relationship between memory B cell deficiency and SHM abnormalities in CVID, and relate these variables to prediagnostic infections. Isotype switched Vh3-23 transcripts were undetectable or low in 30% (IgG) and 63% (IgA) of the patients, but never in controls (P < 0.001). When measurable, the SHM fraction of transcripts was significantly lower in patients (IgM: median 32% vs. 56% (P = 0.0002); IgG: 72% vs. 87% (P = 0.0002); IgA: 81% vs. 88% (P = 0.04)). The concentration of switched (CD19+/CD27+/IgG+) and unswitched (CD19+/CD27+/IgM+/IgD+) memory cells was reduced in 75% and 58% of the patients, respectively. Patients with reduced concentrations of switched memory B cells had normal or low SHM, and only the IgG SHM fraction correlated with prediagnostic incidence of severe respiratory tract infections (P = 0.004).

Abstract
We report on a male patient with bronchiectasis secondary to common variable immune deficiency (CVID) receiving lung transplantation. The patient had been diagnosed with CVID many y prior to right-sided single lung transplantation and was receiving appropriate immunoglobulin substitution therapy. He received antithymocyte globulin induction and maintenance triple therapy with cyclosporine, azathioprine and prednisolone. The early post-operative course was complicated by the development of severe acute cellular rejection and organizing pneumonia. Despite immunoglobulin replacement and antifungal prophylaxis and treatment, Aspergillus fumigatus was repeatedly cultured from bronchoalveolar lavage fluid, 18 months after transplantation. The patient died following a protracted period of repeated hospital admissions, 46 months after transplantation. A review of the literature suggests that many CVID patients appear to have had a complicated post-operative course after lung- and other solid-organ transplantation, and highlights the need for the establishment of international registries for transplanted patients with uncommon conditions.

Abstract
Introduction of personal protective equipment (PPE) in the process of quantitative exposure and risk assessment should be addressed carefully. PPE which have been designed and manufactured according to CE-criteria and have proved to pass relevant test criteria, can be classified as "proper functioning". However, test criteria for PPE are not equal to levels of protection which can be achieved in the workplace, because actual workplace exposure scenarios, fit, maintenance and storage may differ substantially from the test conditions. The proper use of PPE is related to issues which form a part of a PPE-programme. Such a programme should be implemented in a company to ensure selection of proper PPE and information, training and instruction of employees how to wear PPE properly. Assigned protection factors (APFs) for different designs of respiratory protective devices (RPD) have been introduced to quantify effectiveness of RPD in the workplace. Similar APFs are proposed for dermal protection (gloves and clothing). In general biological monitoring studies show lower reduction of internal exposure than estimated by reduction of external exposure. Therefore, conservative estimates of protection by PPE, i.e. the lowest APFs, are proposed for risk assessment purposes if "proper use of proper functioning" PPE as part of a PPE-programme cannot be demonstrated.

Abstract
Exposure assessors involved in regulatory risk assessments often need to estimate a reasonable worst-case full-shift exposure level from very limited exposure information. Full-shift exposure data of very high quality are rare. A full-shift value can also be calculated from (short term) task-based values, either derived from measured data or from models. The most simple option is to use the task based exposure levels as the full-shift value. A second option is to calculate a time-weighted average (TWA), using (reasonable worst case) estimates of the duration and the exposure level of the relevant tasks. The third option is to use a Monte Carlo analysis with estimated input distributions for exposure level and duration of exposure. If an estimated distribution of respiratory volume is also included, this leads to a distribution of inhaled amounts. The 90th percentile of such a distribution is generally substantially lower than the fixed point estimates calculated using high end values for each parameter. This technique can thus prevent unnecessary conservative estimates in risk assessment. The output distribution can also be used as valuable input to the risk management process, because it provides information on probabilities of exposure levels, that can influence the cost-benefit analysis of the risk management process. Finally, the sensitivity analysis of Monte Carlo simulation can give guidance for further studies to increase the accuracy of the exposure assessment.

Abstract
Dermal exposure assessment and modeling is still in early phases of development. This article presents the results of a workshop organized to harmonize the future needs in this field. Methods for dermal exposure assessment either assess the mass of contaminant that is transferred to the skin, or the transfer of contaminant through the skin. Models for dermal exposure are either knowledge-based or deterministic. Any method or model should be transparent, validated, and open to further development. Some (partly) validated and standardized methods are available for measuring or modeling permeation of the skin or of personal protective equipment (PPE). Further validation and standardization is necessary. More research is needed on permeation of dusts and aerosols and more realistic tests should be developed and used for PPE. Several methods have been developed to measure contamination of surfaces or skin, but they are not validated or standardized. A number of non-validated models exist to assess dermal exposure. A clear need exists for more studies of dermal exposure, regarding measurement methods, models and actual exposure levels. A running four-year European study will greatly expand the knowledge in this field. Simple tools to assess and control the risks of dermal exposure in small and medium sized enterprises are also needed. Increasing the general knowledge of practitioners (e.g., safety professionals, occupational hygienists and physicians) in the field of dermal exposure is a first requirement. Available data, for example, on the permeation of PPE, should be made more readily available, using modern information technology. When information on dermal exposure is gathered and stored, the core information needs are partly the same as those for inhalation exposure. Some elements of process and activity, substance and product or worker, specific for dermal exposure, have been suggested by the workshop.

Abstract
Following the recommendations of the European Working Group on Exposure Databases, a Working Group (on Storage of Data of Measurements of Occupational Exposure) of the Dutch Occupational Hygiene Society has developed a Guideline which was presented at the International Symposium on Occupational Exposure Databases and Their Application for the Next Millennium, November 1-3, 1999, London. To establish the present situation, a small-scale telephone survey of monitoring practices and storage of data was done within the Society. The results of the telephone survey and the draft guidance document were discussed with the occupational hygienists and other stakeholders (e.g., authorities, industry, labor unions, and occupational physicians) in a society meeting. This meeting was used to gather ideas on the need and support for a guidance document and to get input for improving the draft guidance document and for implementation of the Guideline. After this meeting, the Guideline was further developed and published by the Dutch Occupational Hygiene Society. The Guideline concentrates on the data elements required when storing exposure data. The data elements presented are the minimum and should be stored minimally to ensure proper interpretation of results at present and in the future and definitions of the items used are given. The Guideline does not prescribe how the data should be stored, or which procedures need to be used to guarantee the quality of the recorded data elements.

Abstract
OBJECTIVE We investigated whether polymorphisms in the gene of mannose binding lectin (MBL) may be associated with onset of rheumatoid arthritis (RA), and whether MBL in conjunction with aggregated agalactosyl IgG (IgG-G0) may be associated with clinical and paraclinical variables. METHODS MBL genotypes and serum concentrations were measured by polymerase chain reaction and ELISA in 189 patients with established RA. Binding of purified MBL to IgG-G0 in serum was assessed and clinical and paraclinical variables were recorded. RESULTS The median age at onset of RA in the 3 genotypes (normal: A/A, hetero: A/0, and homozygous: 0/0 for variant alleles) was 54.1 (n = 108), 47.0 (n = 68), and 38.4 years (n = 13), respectively (p = 0.01). The frequency of variant alleles in patients with onset below the median age (50.8 yrs) was 0.32, but was 0.17 in patients with onset above 50.8 years (p = 0.003) and 0.20 in 250 controls (p = 0.001). Stratification according to erosion score (no, small, large) revealed an increasing tendency among the different groups in binding of MBL to IgG-G0, increased Health Assessment Questionnaire score, and acute phase reactants in A/A individuals, while no difference was seen among carriers of variant alleles. This effect was most pronounced in those with late onset RA. CONCLUSION Presence of MBL variant alleles was associated with early onset of RA. MBL deficiency may, therefore, accelerate the disease. However, in patients with late onset and advanced disease our results indicate that the A/A type may be associated with additional inflammation different from that seen in carriers of variant alleles.

Abstract
OBJECTIVE Some chemokine receptors have been shown to be co-receptors for human immunodeficiency virus (HIV-1). A 32 base pair deletion allele in the CC chemokine receptor 5 gene (CCR5 delta32 allele) affects both transmission of HIV-1 and acquired immunodeficiency syndrome (AIDS)-free survival. Chemokines are suggested to be critical for establishment of inflammatory processes in autoimmune diseases such as rheumatoid arthritis (RA). We hypothesized that the defective allele may modulate the inflammatory process in RA. METHODS Using polymerase chain reaction methods, we investigated the significance of the CCR5 delta32 allele in 163 Danish patients with RA and monitored clinical and paraclinical variables. RESULTS The gene frequency of the CCR5 delta32 allele (0.10) did not deviate significantly from healthy controls and from that reported in healthy Caucasian populations, nor did the distribution deviate from the Hardy-Weinberg predictions (131 wild type, 30 heterozygous, 2 homozygous for the deletion allele; p = 0.85). However, a significantly increased proportion of those carrying the deletion allele were negative for IgM rheumatoid factor (RF) compared to those homozygous for the normal allele (29 vs 9%; p = 0.007). The proportion of CCR5 delta32 allele carriers with swollen joints was decreased compared to those homozygous for the normal allele (35 vs 58%, respectively; p = 0.03), as was the duration of morning stiffness (median 0 vs 60 min, respectively; p = 0.0002). CONCLUSION The CCR5 delta32 allele seems to have some influence on RA variables including RF, which suggests that inhibition of chemokine receptors might be a potential target for disease modifying therapy in RA.

Abstract
On 18 farms for rose culture in greenhouses in The Netherlands, dermal exposure of hands and forearms to abamectin (avermectin B1), dodemorph (4-cyclododecyl-2,6-dimethylmorpholinium acetate) and bupirimate (5-butyl-2-(ethylamino)-6-methyl-4-pyrimidinyl dimethylsulphate) was measured during crop activities. Dermal exposure during cutting (75 workers) amounted to 13 micrograms/h, 1.8 mg/h, and 2.2 mg/h for abamectin, dodemorph and bupirimate, respectively. Dermal exposure to abamectin and dodemorph during sorting (21 workers) and bundling (30 workers) was comparable with that during cutting. From the dependence of dermal exposure on the amount of dislodgeable foliar residue (DFR) a transfer factor was estimated to be 1,200, 4,550, and 2,400 cm2/h for abamectin, dodemorph and bupirimate, respectively. For sorting and bundling these factors were of the same order of magnitude. The results suggested that work rate was also a determinant of dermal exposure. The within-farm variance of dermal exposure during cutting appeared to account for approximately 30% of the unexplained part of the variation remaining after regression on DFR and application technique. The final unexplained part in the variation of dermal exposure during cutting was amongst others due to the variation between the different farms in which the measurements were performed. A health risk evaluation of the observed levels of dermal exposure after re-entry of greenhouses led to the conclusion that a health hazard may exist, especially after application of high rates of relatively toxic pesticides which easily penetrate the skin.

Abstract
Spirometric lung-function measurements were conducted 5 days before and after the work shift of 11 welders of zinc-coated steel, ten nonwelders who were indirectly exposed to welding fumes, and 17 controls. The exposure to dust and zinc of all participants was monitored personally using PAS-6 samplers. Geometric mean concentrations for welders were 0.91 mg/m3 (dust) and 34.0 micrograms/m3 (zinc). Cross-sectional analysis of Monday morning values showed no differences in lung-function parameters between groups. However, the number of years the participants were engaged in welding was of borderline statistical significance and correlated negatively with values of FEV1 and FEV1/FVC. Changes in lung function over a work shift or a working week were not related to the exposure level.
