Bereaved parents' perspectives on their child's end-of-life care: connecting a self-report questionnaire and interview data from the nationwide Paediatric End-of-LIfe CAre Needs in Switzerland (PELICAN) study.

BACKGROUND: Paediatric Palliative Care (PPC) focuses on ensuring the best possible quality of life for the child and his/her family by extending beyond the physical domain into psychosocial and spiritual wellbeing. A deep understanding of what is important to parents is crucial in guiding the further evaluation and improvement of PPC and end-of-life (EOL) care services. Much can be learned from specific positive and negative experiences of bereaved parents with the EOL care of their child. This report builds upon a questionnaire survey as part of the national Paediatric End-of-LIfe CAre Needs in Switzerland (PELICAN) study. METHODS: One part of the PELICAN study was set up to assess and explore the parental perspectives on their child's EOL care. Interview data were used to explain the extremely positive and negative results of a quantitative survey in an explanatory sequential mixed-methods approach. Data integration occurred at different points: during sampling of the interview participants, when designing the interview guide and during analysis. A narrative approach was applied to combine the qualitative results reported here with the already published quantitative survey results. RESULTS: Eighteen mothers (60%) and twelve fathers (40%) participated in 20 family interviews. All parents reported having both positive and negative experiences during their child's illness and EOL, which was characterised by many ups and downs. The families transitioned through phases with a prospect of a cure for some children as well as setbacks and changing health status of the child which influenced prognosis, leading to the challenge of making extremely difficult decisions. Severely negative experiences still haunted and bothered the parents at the time when the interview took place. CONCLUSIONS: A deep understanding of the perspectives and needs of parents going through the devastating event of losing a child is important and a prerequisite to providing compassionate care. This complex care needs to recognise and respond to the suffering not only of the child but of the parents and the whole family. Communication and shared decision-making remain pivotal, as do still improvable elements of care that should build on trustful relationships between families and healthcare professionals.

Specialised Paediatric PAlliativE CaRe: Assessing family, healthcare professionals and health system outcomes in a multi-site context of various care settings: SPhAERA study protocol.

BACKGROUND: The number of children and adolescents living with life-limiting conditions and potentially in need for specialised paediatric palliative care (SPPC) is rising. Ideally, a specialised multiprofessional team responds to the complex healthcare needs of children and their families. The questions of, how SPPC is beneficial, for whom, and under what circumstances, remain largely unanswered in the current literature. This study's overall target is to evaluate the effectiveness of a SPPC programme in Switzerland with respect to its potential to improve patient-, family-, health professional-, and healthcare-related outcomes. METHODS: This comparative effectiveness study applies a quasi-experimental design exploring the effectiveness of SPPC as a complex intervention at one treatment site in comparison with routine care provided in a generalised PPC environment at three comparison sites. As the key goal of palliative care, quality of life - assessed at the level of the patient-, the family- and the healthcare professional - will be the main outcome of this comparative effectiveness research. Other clinical, service, and economic outcomes will include patient symptom severity and distress, parental grief processes, healthcare resource utilisation and costs, direct and indirect health-related expenditure, place of death, and introduction of SPPC. Data will be mainly collected through questionnaire surveys and chart analysis. DISCUSSION: The need for SPPC has been demonstrated through numerous epidemiological and observational studies. However, in a healthcare environment focused on curative treatment and struggling with limited resources, the lack of evidence contributes to a lack of acceptance and financing of SPPC which is a major barrier against its sustainability. This study will contribute to current knowledge by reporting individual and child level outcomes at the family level and by collecting detailed contextual information on healthcare provision. We hope that the results of this study can help guiding the expansion and sustainability of SPPC and improve the quality of care for children with life-limiting conditions and their families internationally.

Measuring Financial Burden in Families of Children Living With Life-Limiting Conditions: A Scoping Review of Cost Indicators and Outcome Measures.

OBJECTIVES: This study aimed to provide a comprehensive overview of cost indicators and outcome measures used to measure financial burden in families of children with life-limiting conditions. METHODS: A scoping review methodology was used to map the existing literature and provide an overview of available cost indicators and outcome measures. Key medical, economic, and scientific databases were systematically searched to identify relevant articles published in 2000 or later. RESULTS: The database search yielded 7194 records, including 30 articles eligible for final inclusion. Retrieved cost indicators and outcome measures fell into 3 broad categories: direct costs, indirect costs, and financial support. No study comprehensively assessed all 3 categories. Cost indicators used to measure direct costs were grouped into 5 medical and 11 nonmedical out-of-pocket expenses categories, of which 5 were commonly assessed (ie, treatment and diagnostics, travel and transport, accommodation, food, childcare and home help). Half of the reviewed studies included assessments of indirect costs, most commonly estimating work-related income loss by evaluating employment disruptions. Assessments of opportunity costs arising from informal caregiving and of financial support were rarely included. CONCLUSIONS: Current estimates of the financial burden faced by families of children with life-limiting conditions are inconsistent and often incomplete, likely resulting in severe underestimations of the costs these families incur. We hope that the framework presented in this article will contribute to a more comprehensive assessment of illness-related financial burden and help guide future policies in this area.

Differing needs of mothers and fathers during their child's end-of-life care: secondary analysis of the "Paediatric end-of-life care needs" (PELICAN) study.

BACKGROUND: Mothers and fathers are severely challenged when providing care for their terminally ill child at end of life. Caregiving needs have been studied predominantly in mothers. Differences in caregiving needs between mothers and fathers during their child's end of life have not, however, been explored so far. This knowledge is of importance to best meet individual parental needs in paediatric end-of-life care. METHODS: Secondary analysis of a quantitative survey on parental needs during their child's last 4 weeks of life, collected in the Swiss multicentre "Paediatric End-of-Life Care Needs" (PELICAN) study. Caregiving needs of mothers and fathers (parental dyad) who had lost a child due to a cardiological, neurological or oncological disease or during the neonatal period in the years 2011-2012 were retrospectively assessed using a questionnaire representing six evidence-based quality domains of paediatric palliative and end-of-life care. RESULTS: Seventy-eight parental dyads were included in this analysis. Differences between mothers and fathers were mostly found around needs to be supported as a family. In all, 28 out of 34 needs-related questionnaire items were scored higher by mothers than by fathers, indicating higher importance for that need to be met. The results indicate that these differences might relate to different caregiving roles and gender-specific coping strategies. CONCLUSIONS: To best meet parental needs in paediatric end-of-life care, particular attention should be paid to both mothers and fathers and their specific caregiving roles, as differences in these roles might influence their needs in this exceptional situation. Therefore, healthcare professionals should identify how parental dyads mutually navigate care for their sick child to best meet their needs in support. Additionally, mothers and fathers should be supported in their individual coping strategies.

Comparative assessment of differential network analysis methods.

Differential network analysis (DiNA) denotes a recent class of network-based Bioinformatics algorithms which focus on the differences in network topologies between two states of a cell, such as healthy and disease, to identify key players in the discriminating biological processes. In contrast to conventional differential analysis, DiNA identifies changes in the interplay between molecules, rather than changes in single molecules. This ability is especially important in cases where effectors are changed, e.g. mutated, but their expression is not. A number of different DiNA approaches have been proposed, yet a comparative assessment of their performance in different settings is still lacking. In this paper, we evaluate 10 different DiNA algorithms regarding their ability to recover genetic key players from transcriptome data. We construct high-quality regulatory networks and enrich them with co-expression data from four different types of cancer. Next, we assess the results of applying DiNA algorithms on these data sets using a gold standard list (GSL). We find that local DiNA algorithms are generally superior to global algorithms, and that all DiNA algorithms outperform conventional differential expression analysis. We also assess the ability of DiNA methods to exploit additional knowledge in the underlying cellular networks. To this end, we enrich the cancer-type specific networks with known regulatory miRNAs and compare the algorithms performance in networks with and without miRNA. We find that including miRNAs consistently and considerably improves the performance of almost all tested algorithms. Our results underline the advantages of comprehensive cell models for the analysis of -omics data.

T-cell repertoires in refractory coeliac disease.

OBJECTIVE: Refractory coeliac disease (RCD) is a potentially hazardous complication of coeliac disease (CD). In contrast to RCD type I, RCD type II is a precursor entity of enteropathy-associated T-cell lymphoma (EATL), which is associated with clonally expanding T-cells that are also found in the sequentially developing EATL. Using high-throughput sequencing (HTS), we aimed to establish the small-intestinal T-cell repertoire (TCR) in CD and RCD to unravel the role of distinct T-cell clonotypes in RCD pathogenesis. DESIGN: DNA extracted from duodenal mucosa specimens of controls (n=9), active coeliacs (n=10), coeliacs on a gluten-free diet (n=9), RCD type I (n=8), RCD type II (n=8) and unclassified Marsh I cases (n=3) collected from 2002 to 2013 was examined by TCRß-complementarity-determining regions 3 (CDR3) multiplex PCR followed by HTS of the amplicons. RESULTS: On average, 106 sequence reads per sample were generated consisting of up to 900 individual TCRß rearrangements. In RCD type II, the most frequent clonotypes (ie, sequence reads with identical CDR3) represent in average 42.6% of all TCRß rearrangements, which was significantly higher than in controls (6.8%; p<0.01) or RCD type I (6.7%; p<0.01). Repeat endoscopies in individual patients revealed stability of clonotypes for up to several years without clinical symptoms of EATL. Dominant clonotypes identified in individual patients with RCD type II were unique and not related between patients. CD-associated, gliadin-dependent CDR3 motifs were only detectable at low frequencies. CONCLUSIONS: TCRß-HTS analysis unravels the TCR in CD and allows detailed analysis of individual TCRß rearrangements. Dominant TCRß sequences identified in patients with RCD type II are unique and not homologous to known gliadin-specific TCR sequences, supporting the assumption that these clonal T-cells expand independent of gluten stimulation.

Patterns of paediatric end-of-life care: a chart review across different care settings in Switzerland.

BACKGROUND: Paediatric end-of-life care is challenging and requires a high level of professional expertise. It is important that healthcare teams have a thorough understanding of paediatric subspecialties and related knowledge of disease-specific aspects of paediatric end-of-life care. The aim of this study was to comprehensively describe, explore and compare current practices in paediatric end-of-life care in four distinct diagnostic groups across healthcare settings including all relevant levels of healthcare providers in Switzerland. METHODS: In this nationwide retrospective chart review study, data from paediatric patients who died in the years 2011 or 2012 due to a cardiac, neurological or oncological condition, or during the neonatal period were collected in 13 hospitals, two long-term institutions and 10 community-based healthcare service providers throughout Switzerland. RESULTS: Ninety-three (62%) of the 149 reviewed patients died in intensive care units, 78 (84%) of them following withdrawal of life-sustaining treatment. Reliance on invasive medical interventions was prevalent, and the use of medication was high, with a median count of 12 different drugs during the last week of life. Patients experienced an average number of 6.42 symptoms. The prevalence of various types of symptoms differed significantly among the four diagnostic groups. Overall, our study patients stayed in the hospital for a median of six days during their last four weeks of life. Seventy-two patients (48%) stayed at home for at least one day and only half of those received community-based healthcare. CONCLUSIONS: The study provides a wide-ranging overview of current end-of-life care practices in a real-life setting of different healthcare providers. The inclusion of patients with all major diagnoses leading to disease- and prematurity-related childhood deaths, as well as comparisons across the diagnostic groups, provides additional insight and understanding for healthcare professionals. The provision of specialised palliative and end-of-life care services in Switzerland, including the capacity of community healthcare services, need to be expanded to meet the specific needs of seriously ill children and their families.

DCLRE1C (ARTEMIS) mutations causing phenotypes ranging from atypical severe combined immunodeficiency to mere antibody deficiency.

Null mutations in genes involved in V(D)J recombination cause a block in B- and T-cell development, clinically presenting as severe combined immunodeficiency (SCID). Hypomorphic mutations in the non-homologous end-joining gene DCLRE1C (encoding ARTEMIS) have been described to cause atypical SCID, Omenn syndrome, Hyper IgM syndrome and inflammatory bowel disease-all with severely impaired T-cell immunity. By whole-exome sequencing, we investigated the molecular defect in a consanguineous family with three children clinically diagnosed with antibody deficiency. We identified perfectly segregating homozygous variants in DCLRE1C in three index patients with recurrent respiratory tract infections, very low B-cell numbers and serum IgA levels. In patients, decreased colony survival after irradiation, impaired proliferative response and reduced counts of naïve T cells were observed in addition to a restricted T-cell receptor repertoire, increased palindromic nucleotides in the complementarity determining regions 3 and long stretches of microhomology at switch junctions. Defective V(D)J recombination was complemented by wild-type ARTEMIS protein in vitro. Subsequently, homozygous or compound heterozygous DCLRE1C mutations were identified in nine patients from the same geographic region. We demonstrate that DCLRE1C mutations can cause a phenotype presenting as only antibody deficiency. This novel association broadens the clinical spectrum associated with ARTEMIS mutations. Clinicians should consider the possibility that an immunodeficiency with a clinically mild initial presentation could be a combined immunodeficiency, so as to provide appropriate care for affected patients.

Maintaining family life balance while facing a child's imminent death-A mixed methods study.

AIM: To understand parents' experiences and needs during a child's end-of-life care at home and to identify systemic factors that influence its provision. BACKGROUND: A child's end-of-life phase is an extremely difficult time for the whole family. Parents have specific needs, especially when they care for a dying child at home. DESIGN: Concurrent embedded mixed methods design. METHODS: This sub-study of the nationwide survey, 'Paediatric End-of-Life Care Needs in Switzerland' (2012-2015) included 47 children who received EOL care at home from 2011-2012. We extracted quantitative data from patients' medical charts and obtained information via parental questionnaire and then compared parents whose child died at home or in hospital by computing generalized estimation equations. We thematically analysed interviews with parents who provided EOL care at home. RESULTS: Parents created an intimate lifeworld and a sense of normality for the child at home. They constantly balanced the family's lifeworld with the requirements and challenges posed by the outside world. This work exhausted parents. Parental 'readiness' and social support drove EOL care for children at home. Parents needed practical help with housekeeping and had negative experiences when dealing with insurance. In only 34.8% of cases was a child's EOL home care supported by paediatric palliative care team. CONCLUSION: Paediatric end-of-life care at home is only feasible if parents make extraordinary efforts. If family-centred end-of-life home care is provided by a hospital-based paediatric palliative home care team, which includes paid housekeeping help and psychological support, parents' needs could be better met.

When parents face the death of their child: a nationwide cross-sectional survey of parental perspectives on their child's end-of life care.

BACKGROUND: Parents facing the death of their child have a strong need for compassionate professional support. Care services should be based on empirical evidence, be sensitive to the needs of the families concerned, take into account the heterogeneity within the medical field of paediatrics, and fit into the local health care system. We need to better understand the perspectives of parents facing the death of their child in order to guide further development and evaluation of specialised paediatric palliative and end-of-life (EOL) care services. METHODS: Questionnaire survey to assess the EOL care perspectives of a Swiss population-based sample of bereaved parents who had lost a child due to a cardiac, neurological or oncological condition, or during the neonatal period in the years 2011 or 2012. The parental perspective was assessed with a newly developed and tested instrument that was structured according to six evidence-based quality domains. Responses regarding parental experiences and perceived satisfaction are described. Differences between the four diagnostic groups are analysed using a generalized estimation equation to account for the dyadic data structure. RESULTS: Of 307 eligible families, 267 could be contacted and 135 (51%) consented to participate in this questionnaire survey. Our findings show positive parental experiences of their child's EOL care and high perceived satisfaction with the care their child received. Parents of a child with cancer rated their experiences highest in most of the six quality domains and reported the highest satisfaction with care. The lowest scores were mainly reported by parents from the neurology group, with the exception of the shared decision making domain, where parents of neonates reported significantly less positive experiences. CONCLUSIONS: Although positive in general, our study results suggest some areas for improvement. The integration of specialised paediatric palliative care has the potential to minimise lost opportunities to support and assist parents.

Algorithms for differential splicing detection using exon arrays: a comparative assessment.

BACKGROUND: The analysis of differential splicing (DS) is crucial for understanding physiological processes in cells and organs. In particular, aberrant transcripts are known to be involved in various diseases including cancer. A widely used technique for studying DS are exon arrays. Over the last decade a variety of algorithms for the detection of DS events from exon arrays has been developed. However, no comprehensive, comparative evaluation including sensitivity to the most important data features has been conducted so far. To this end, we created multiple data sets based on simulated data to assess strengths and weaknesses of seven published methods as well as a newly developed method, KLAS. Additionally, we evaluated all methods on two cancer data sets that comprised RT-PCR validated results. RESULTS: Our studies indicated ARH as the most robust methods when integrating the results over all scenarios and data sets. Nevertheless, special cases or requirements favor other methods. While FIRMA was highly sensitive according to experimental data, SplicingCompass, MIDAS and ANOSVA showed high specificity throughout the scenarios. On experimental data ARH, FIRMA, MIDAS, and KLAS performed best. CONCLUSIONS: Each method shows different characteristics regarding sensitivity, specificity, interference to certain data settings and robustness over multiple data sets. While some methods can be considered as generally good choices over all data sets and scenarios, other methods show heterogeneous prediction quality on the different data sets. The adequate method has to be chosen carefully and with a defined study aim in mind.

Paediatric end-of-life care in the home care setting (PELICAN HOME)--a mixed methods study protocol.

AIMS: (a) To explore parental experiences and needs during their child's end-of-life care at home; (b) to explore patient's characteristics and current provision of paediatric end-of-life care in the home care setting in Switzerland; and (c) to determine influencing system factors impacting end-of-life care at home. BACKGROUND: Parental experiences/needs and paediatric end-of-life care services in the home care setting are influenced by national healthcare policy, determinants of the family and the individual patient. In Switzerland, there is a lack of information about the provision of paediatric end-of-life care at home and related parent's experiences/needs. DESIGN: Sub-study of the nationwide multicenter study 'Paediatric End-of-Life CAre Needs in Switzerland' using a concurrent qualitative embedded mixed methods design. METHODS: Data will be collected from January-May 2014 through community care organizations and children's hospitals. The study includes approximately 40-50 families whose child (0-18 years) died in the years 2011-2012 due to a cardiological, neurological or oncological condition and spent at least 21 days at home during the last 4 weeks of life. Qualitative data will be collected through semi-structured interviews with parents and analysed by 'thematic analysis'. Quantitative data about patient's characteristics will be obtained from patient's medical charts and parental experiences/needs through the parental questionnaire. Appropriate descriptive and inference statistical methods will be used for data analysis. DISCUSSION: This study will provide comprehensive basic information about parental needs and patient characteristics for the provision of paediatric end-of-life care and may promote the development of family-centred paediatric end-of-life care services at home. STUDY REGISTRATION: The PELICAN-study is registered in the database of Clinical Trial gov. Study ID-number: NCT 01983852.

Paediatric end-of-life care needs in Switzerland: current practices, and perspectives from parents and professionals. A study protocol.

AIM: To present a protocol for a multi-phase study about the current practice of end-of-life care in paediatric settings in Switzerland. BACKGROUND: In Switzerland, paediatric palliative care is usually provided by teams, who may not necessarily have specific training. There is a lack of systematic data about specific aspects of care at the end of a child's life, such as symptom management, involvement of parents in decision-making and family-centred care and experiences and needs of parents, and perspectives of healthcare professionals. DESIGN: This retrospective nationwide multicentre study, Paediatric End-of-LIfe CAre Needs in Switzerland (PELICAN), combines quantitative and qualitative methods of enquiry. METHODS: The PELICAN study consists of three observational parts, PELICAN I describes practices of end-of-life care (defined as the last 4 weeks of life) in the hospital and home care setting of children (0-18 years) who died in the years 2011-2012 due to a cardiac, neurological or oncological disease, or who died in the neonatal period. PELICAN II assesses the experiences and needs of parents during the end-of-life phase of their child. PELICAN III focuses on healthcare professionals and explores their perspectives concerning the provision of end-of-life care. CONCLUSION: This first study across Switzerland will provide comprehensive insight into the current end-of-life care in children with distinct diagnoses and the perspectives of affected parents and health professionals. The results may facilitate the development and implementation of programmes for end-of-life care in children across Switzerland, building on real experiences and needs. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01983852.

Development and initial validation of the Parental PELICAN Questionnaire (PaPEQu)--an instrument to assess parental experiences and needs during their child's end-of-life care.

AIM: To develop and test the Parental PELICAN Questionnaire, an instrument to retrospectively assess parental experiences and needs during their child's end-of-life care. BACKGROUND: To offer appropriate care for dying children, healthcare professionals need to understand the illness experience from the family perspective. A questionnaire specific to the end-of-life experiences and needs of parents losing a child is needed to evaluate the perceived quality of paediatric end-of-life care. DESIGN: This is an instrument development study applying mixed methods based on recommendations for questionnaire design and validation. METHOD: The Parental PELICAN Questionnaire was developed in four phases between August 2012-March 2014: phase 1: item generation; phase 2: validity testing; phase 3: translation; phase 4: pilot testing. Psychometric properties were assessed after applying the Parental PELICAN Questionnaire in a sample of 224 bereaved parents in April 2014. Validity testing covered the evidence based on tests of content, internal structure and relations to other variables. RESULTS: The Parental PELICAN Questionnaire consists of approximately 90 items in four slightly different versions accounting for particularities of the four diagnostic groups. The questionnaire's items were structured according to six quality domains described in the literature. Evidence of initial validity and reliability could be demonstrated with the involvement of healthcare professionals and bereaved parents. CONCLUSION: The Parental PELICAN Questionnaire holds promise as a measure to assess parental experiences and needs and is applicable to a broad range of paediatric specialties and settings. Future validation is needed to evaluate its suitability in different cultures.

Tools for managing and analyzing microarray data.

The microarray-based analysis of gene expression has become a workhorse for biomedical research. Managing the amount and diversity of data that such experiments produce is a task that must be supported by appropriate software tools, which led to the creation of literally hundreds of systems. In consequence, choosing the right tool for a given project is difficult even for the expert. We report on the results of a survey encompassing 78 of such tools, of which 22 were inspected in detail and seven were tested hands-on. We report on our experiences with a focus on completeness of functionality, ease-of-use, and necessary effort for installation and maintenance. Thereby, our survey provides a valuable guideline for any project considering the use of a microarray data management system. It reveals which tasks are covered by mature tools and also shows that important requirements, especially in the area of integrated analysis of different experimental data, are not yet met satisfyingly by existing systems.

C/EBPß-induced lymphoid-to-myeloid transdifferentiation emulates granulocyte-monocyte progenitor biology.

CCAAT/enhancer-binding protein beta (C/EBPß) induces primary v-Abl immortalized mouse B cells to transdifferentiate (BT, B cell transdifferentiation) into granulocyte-macrophage progenitor-like cells (GMPBTs). GMPBTs maintain cytokine-independent self-renewal, lineage choice, and multilineage differentiation. Single-cell transcriptomics demonstrated that GMPBTs comprise a continuum of myelomonopoietic differentiation states that seamlessly fit into state-to-fate maps of normal granulocyte-macrophage progenitors (GMPs). Inactivating v-Abl kinase revealed the dependence on activated CSF2-JAK2-STAT5 signaling. Deleting IRF8 diminished monopoiesis and enhanced granulopoiesis while removing C/EBPß-abrogated self-renewal and granulopoiesis but permitted macrophage differentiation. The GMPBT culture system is easily scalable to explore the basics of GMP biology and lineage commitment and largely reduces ethically and legislatively debatable, labor-intensive, and costly animal experiments.

Work-related quality of life in professionals involved in pediatric palliative care: a repeated cross-sectional comparative effectiveness study.

Background: Working in pediatric palliative care (PPC) impacts healthcare and allied professionals' work-related quality of life (QoL). Professionals who lack specific PPC training but who regularly provide services to the affected children have articulated their need for support from specialized PPC (SPPC) teams. Objectives: This study had two objectives: (1) to evaluate whether the availability of a SPPC team impacted the work-related QoL of professionals not specialized in PPC; and (2) to explore the work-related QoL of professionals working in PPC without specialized training. Design: Repeated cross-sectional comparative effectiveness design. Methods: One hospital with an established SPPC program and affiliated institutions provided the intervention group (IG). Three hospitals and affiliated institutions where generalist PPC was offered provided the comparison group (CG). Data were collected by paper-pencil questionnaire in 2021 and 2022. The Professional Quality of Life (ProQOL 5) questionnaire was used to assess work-related QoL, yielding separate scores for burnout (BO), secondary traumatic stress (STS) and compassion satisfaction (CS). A descriptive statistical analysis was performed and general estimation equations were modelled. To increase the comparability of the IG and CG, participants were matched by propensity scores. Results: The 301 participating non-PPC-specialized professionals had overall low to moderate levels of BO and STS and moderate to high levels of CS. However, none of these scores (BO: p = 0.36; STS: p = 0.20; CS: p = 0.65) correlated significantly with support from an SPPC team. Compared to nurses, physicians showed higher levels of BO (1.70; p = 0.02) and STS (2.69; p ⩽ 0.001). Conclusion: Although the study sample's overall work-related QoL was satisfactory, it showed a considerable proportion of moderate BO and STS, as well as moderate CS. To provide tailored support to professionals working in PPC, evidence regarding key SPPC support elements and their effectiveness is needed. Trial registration: ClinicalTrials.gov ID, NCT04236180.

Work-related quality of life in professionals involved in pediatric palliative care - Why was this study done? Caring for children suffering from life-limiting conditions and their families impacts professionals' work-related Quality of Life (QoL). Professionals without specific training often provide pediatric palliative care (PPC) to children and their families. - What did the researchers do? We aimed to determine whether the work-related the QoL of professionals without specialised PPC training would be positively influenced when they were supported by PPC specialists. We also wanted to explore what person-specific factors might correspond with higher or lower work-related QoL. Work-related QoL was analysed in relation to burnout (BO), secondary traumatic stress (STS), and compassion satisfaction (CS). These variables' levels were assessed with a questionnaire survey in 2021 and 2022. - What did the researchers find? The 301 participating professionals had overall low to moderate levels of BO and STS and moderate to high levels of CS. There was no substantial difference in work-related QoL in the professionals supported by PPC specialists compared to those who did not receive specialist support. Physicians showed higher levels of BO and STS than nurses. - What do the findings mean? Although the studied professionals' overall work-related QoL was satisfactory, there is a considerable proportion of moderate BO and STS scores in professionals working with children suffering from life-limiting conditions. Further research should explore the specific needs of professionals not specialised in PPC.

Histone acetylation and DNA demethylation of T cells result in an anaplastic large cell lymphoma-like phenotype.

A characteristic feature of anaplastic large cell lymphoma is the significant repression of the T-cell expression program despite its T-cell origin. The reasons for this down-regulation of T-cell phenotype are still unknown. To elucidate whether epigenetic mechanisms are responsible for the loss of the T-cell phenotype, we treated anaplastic large cell lymphoma and T-cell lymphoma/leukemia cell lines (n=4, each) with epigenetic modifiers to evoke DNA demethylation and histone acetylation. Global gene expression data from treated and untreated cell lines were generated and selected, and differentially expressed genes were evaluated by real-time reverse transcriptase polymerase chain reaction and western blot analysis. Additionally, histone H3 lysine 27 trimethylation was analyzed by chromatin immunoprecipitation. Combined DNA demethylation and histone acetylation of anaplastic large cell lymphoma cells was not able to reconstitute their T-cell phenotype. Instead, the same treatment induced in T cells: (i) an up-regulation of anaplastic large cell lymphoma-characteristic genes (e.g. ID2, LGALS1, c-JUN), and (ii) an almost complete extinction of their T-cell phenotype including CD3, LCK and ZAP70. In addition, suppressive trimethylation of histone H3 lysine 27 of important T-cell transcription factor genes (GATA3, LEF1, TCF1) was present in anaplastic large cell lymphoma cells, which is in line with their absence in primary tumor specimens as demonstrated by immunohistochemistry. Our data suggest that epigenetically activated suppressors (e.g. ID2) contribute to the down-regulation of the T-cell expression program in anaplastic large cell lymphoma, which is maintained by trimethylation of histone H3 lysine 27.

Malnutrition in pediatric patients with cancer at diagnosis and throughout therapy: A multicenter cohort study.

BACKGROUND: Malnutrition is a common problem in pediatric patients with cancer. Reported prevalence varies widely and has often been assessed only in a subset of childhood types of cancer. This study aimed to describe the prevalence of malnutrition among pediatric patients newly diagnosed with cancer, to describe the occurrence and course of malnutrition during therapy and to identify factors associated with malnutrition during therapy. PROCEDURE: In a retrospective cohort study of 327 patients diagnosed from 2003 to 2006 in three Swiss tertiary care hospitals, weight and height measures together with patient-, disease-, and treatment-related characteristics were assessed. Malnutrition was defined as body mass index (BMI) below -2 standard deviation scores (SDS) or a weight loss >10% from diagnosis. Malnutrition was assessed at diagnosis and continuously during anticancer therapy. RESULTS: At diagnosis, 5.8% of the patients (19) were malnourished based on BMI. During anticancer therapy, the cumulative incidence of malnutrition rose to 22% (70 patients) after 30 days, to 36% (116 patients) after 60 days, and finally to 47% (155 patients). In these 155 patients, the median duration of malnutrition was 60 days (interquartile range, 21-122). Age above 10 years at diagnosis, BMI ≤ -1.0 SDS at diagnosis, and a diagnosis of medulloblastoma were positively associated with a higher proportion of malnutrition time during therapy. CONCLUSIONS: The rapid increase of malnutrition after the start of treatment underlines the need to develop evidence-based and efficient methods to provide nutritional support for children with cancer.
