Induction of the pro-myelocytic leukaemia gene by type I and type II interferons.
The physiological role of the pro-myelocytic leukaemia (PML) gene product is poorly defined. Among other functions, PML is involved in haematopoietic differentiation and in control of cell growth and tumorigenesis. We investigated the regulation of human PML expression by interferons (IFNs) and IL-1 in various human haematopoietic lines (U937, THP1, HL60, NB4), in human diploid fibroblasts and in human peripheral blood leukocytes. Cytokine-induced modulation of PML expression was assessed by Northern blot analyses, flow cytometry studies and in situ immunolabelling. Our data show that IFNs and IL-1 upregulate PML transcript and protein expression in a time and dose-dependent manner. In situ immunolabelling revealed that upregulation of protein expression by IFN-alpha is a consequence of a marked increase in both the number and the intensity of the staining of so-called PML nuclear bodies. Our data suggest that stimulation of PML expression by interferons and IL-1 may account for upregulation of PML proteins observed in inflammatory tissues and in proliferative states
Time, institutional support and quality of decision making in child protection:A cross-country analysis
This paper examines perceptions of time and institutional support for decision making and staff confidence in child welfare staffs ultimate decisions – examining differences and similarities between and within the service-oriented Nordic countries (Norway and Finland) and the risk-oriented Anglo-American countries (England and California). The study identifies a high degree of work pressure across all the countries, lines of predominantly vertical institutional support and relatively high confidence in decisions. Finland stands out with higher perceived work pressure and with a horizontal support line, whereas England stands out with workers having a lower degree of confidence in their own and others’ decisions
Pharmacological inhibition of c-Abl compromises genetic stability and DNA repair in Bcr-Abl-negative cells
Imatinib inhibits the kinase activity of Bcr-Abl and is currently the most effective drug for treatment of chronic myeloid leukemia (CML). Imatinib also blocks c-Abl, a physiological tyrosine kinase activated by a variety of stress signals including damaged DNA. We investigated the effect of pharmacological inhibition of c-Abl on the processing of irradiation-induced DNA damage in Bcr-Abl-negative cells. Cell lines and peripheral blood mononuclear cells (PBMCs) from healthy volunteers were treated with imatinib or dasatinib before gamma-irradiation. Inhibition of c-Abl caused an enhanced irradiation-induced mutation frequency and slowdown of DNA repair, whereas imatinib was ineffective in cells expressing a T315I variant of c-Abl. Mutation frequency and repair kinetics were also studied in c-Abl-/- murine embryonic fibroblasts (MEFs) retransfected with wild-type c-Abl (wt-Abl) or a kinase-defect variant of Abl (KD-Abl). Enhanced mutation frequency as well as delayed DNA repair was observed in cells expressing KD-Abl. These data indicate that pharmacological inhibition of c-Abl compromises DNA-damage response
Marker-free cell discrimination by holographic optical tweezers
We introduce a method for marker-free cell discrimination based on optical tweezers. Cancerous, non-cancerous, and drug-treated cells could be distinguished by measuring the trapping forces using holographic optical tweezers. We present trapping force measurements on different cell lines: normal pre-B lymphocyte cells (BaF3; "normal cells"), their Bcr-Abl transformed counterparts (BaF3-p185; "cancer cells") as a model for chronic myeloid leukaemia (CML) and Imatinib treated BaF3-p185 cells. The results are compared with reference measurements obtained by a commercial flow cytometry system
Issues concerning the implementation of the CCS Directive in the Netherlands
In June 2009, the EU Directive on the Geological Storage of Carbon Dioxide entered into force. The European Member states are obliged to transpose the directive in their national legislations no later than 25 June 2011. The EU legislator has applied a regime of minimum harmonisation when drafting the CCS Directive, amongst others to achieve that an agreement could be reached on the CCS Directive by a majority of Member States. In other words; Member States have considerable discretionary powers while implementing the Directive. The CO2 Storage Directive is mainly transposed into Dutch legislation by means of adaptation of the Dutch Mining Act. There are, however, still some issues in the implementation of this directive that need further clarification. The way these issues are addressed may impact the deployment of large-scale CO2 capture and storage (CCS) in the Netherlands and Europ
DNA methylation is associated with downregulation of the organic cation transporter OCT1 (SLC22A1) in human hepatocellular carcinoma
Spiritual well-being and associated factors in Dutch patients with advanced cancer
CONTEXT: Palliative care aims to support patients' spiritual needs with the intention of promoting their spiritual well-being (SWB), an important dimension of quality of life. SWB is one of the less-studied dimensions of QoL, particularly in a secular country such as the Netherlands. OBJECTIVES: In this study we aimed to get a better understanding of SWB in Dutch patients with advanced cancer. We therefore examined its prominence and associated factors. METHODS: We used the baseline data of a cohort study on experienced quality of care and quality of life (eQuiPe study), which included 1,103 patients with advanced cancer. In addition to sociodemographic and religious/spiritual characteristics, study measures comprised the SWB subscales Meaning, Peace, and Faith of the revised FACIT-Sp-12, spiritual problems and needs (PNPCsv), quality of life (EORTC-QLQ-C30) and satisfaction with healthcare professionals' interpersonal skills (INPATSAT-32). RESULTS: On average, patients experienced quite a bit of Meaning (8.9, SD 2.3), a little bit to somewhat Peace (6.8, SD 2.7), and very low levels of Faith (2.9, SD 3.7). Two-thirds (71%) of patients reported one or more spiritual problems, for which the majority (54%) wanted to receive attention. In the final multivariable models, only a few factors were associated with SWB, such as greater spiritual needs with lower levels of Meaning and Peace. CONCLUSION: Dutch patients with advanced cancer experience medium to low levels of Meaning, Peace, and Faith. More attention for their SWB is warranted
Reduction in potentially inappropriate end-of-life hospital care for cancer patients during the COVID-19 pandemic:A retrospective population-based study
Background: The COVID-19 pandemic impacted cancer diagnosis and treatment. However, little is known about end-of-life cancer care during the pandemic. Aim: To investigate potentially inappropriate end-of-life hospital care for cancer patients before and during the COVID-19 pandemic. Design: Retrospective population-based cohort study using data from the Netherlands Cancer Registry and the Dutch National Hospital Care Registration. Potentially inappropriate care in the last month of life (chemotherapy administration, >1 emergency room contact, >1 hospitalization, hospitalization >14 days, intensive care unit admission or hospital death) was compared between four COVID-19 periods and corresponding periods in 2018/2019. Participants: A total of 112,919 cancer patients (⩾18 years) who died between January 2018 and May 2021 were included. Results: Fewer patients received potentially inappropriate end-of-life care during the COVID-19 pandemic compared to previous years, especially during the first COVID-19 peak (22.4% vs 26.0%). Regression analysis showed lower odds of potentially inappropriate end-of-life care during all COVID-19 periods (between OR 0.81; 95% CI 0.74–0.88 and OR 0.92; 95% CI 0.87–0.97) after adjustment for age, sex and cancer type. For the individual indicators, fewer patients experienced multiple or long hospitalizations, intensive care unit admission or hospital death during the pandemic. Conclusions:Cancer patients received less potentially inappropriate end-of-life care during the COVID-19 pandemic. Because several factors may have contributed, it is unclear whether this reflects better quality care. However, these findings raise important questions about what pandemic-induced changes in care practices can help provide appropriate end-of-life care for future patients in the context of increasing patient numbers and limited resources.</p
