RESUMO

Nurses and midwives of Australia now is the time for change! As powerfully placed, Indigenous and non-Indigenous nursing and midwifery professionals, together we can ensure an effective and robust Indigenous curriculum in our nursing and midwifery schools of education. Today, Australia finds itself in a shifting tide of social change, where the voices for better and safer health care ring out loud. Voices for justice, equity and equality reverberate across our cities, our streets, homes, and institutions of learning. It is a call for new songlines of reform. The need to embed meaningful Indigenous health curricula is stronger now than it ever was for Australian nursing and midwifery. It is essential that nursing and midwifery leadership continue to build an authentic collaborative environment for Indigenous curriculum development. Bipartisan alliance is imperative for all academic staff to be confident in their teaching and learning experiences with Indigenous health syllabus. This paper is a call out. Now is the time for Indigenous and non-Indigenous nurses and midwives to make a stand together, for justice and equity in our teaching, learning, and practice. Together we will dismantle systems, policy, and practices in health that oppress. The Black Lives Matter movement provides us with a 'now window' of accepted dialogue to build a better, culturally safe Australian nursing and midwifery workforce, ensuring that Black Lives Matter in all aspects of health care.

RESUMO

BACKGROUND: Haemopoietic stem cell transplantation (HSCT) is a life-saving but intensive procedure associated with potentially severe adverse late effects. We aimed to determine morbidity and health-related quality of life (HRQOL) in a sample of survivors aged 8-18 years at least 1 year post HSCT for paediatric acute leukaemia, compared with a non-transplanted group of survivors matched for age, gender, initial disease and time since treatment. METHODS: Families (N = 54; HSCT n= 29) recruited from four UK centres completed measures of child behaviour and school attendance, HRQOL and finances. Mothers completed measures of their own well-being. Clinical outcome data were extracted from medical records. RESULTS: Children in the HSCT group had significantly more late effects and had received more tests for vision, bone, dental and skin health, and thyroid, lung, and gonadal function than the non-transplanted group. HRQOL scores for the HSCT group were significantly lower in all domains compared with the non-transplanted group and population norms, but were not significantly related to clinical indices. Mothers in the HSCT group had significantly poorer mental well-being than population norms. CONCLUSION: Significant morbidity and compromised HRQOL was found in survivors of HSCT. The burden of caring for a child after HSCT has a continuing toll on mothers' well-being.The importance of counselling families about possible long-term consequences is emphasized.

RESUMO

The considerable clinical heterogeneity of patients with common variable immunodeficiency disorders (CVID) shares some similarity with bone-marrow failure disorders such as Diamond-Blackfan anaemia (DBA) and Shwachman-Diamond syndrome (SDS), now recognized as defects in ribosome biogenesis or ribosomopathies. The recognition of a patient with DBA who subsequently developed CVID lends support to our previous finding of a heterozygous mutation in the SBDS gene of SBDS in another CVID patient, suggesting that ribosome biogenesis defects are responsible for a subset of CVID. Genetic defects in the ribosomal translational machinery responsible for various bone marrow failure syndromes are recognized readily when they manifest in children, but diagnosing these in adults presenting with complex phenotypes and hypogammaglobulinaemia can be a challenge. In this perspective paper, we discuss our clinical experience in CVID patients with ribosomopathies, and review the immunological abnormalities in other conditions associated with ribosomal dysfunction. With genetic testing available for various bone marrow failure syndromes, our hypothesis that ribosomal abnormalities may be present in patients with CVID could be proved in future studies by testing for mutations in specific ribosomal genes. New knowledge might then be translated into novel therapeutic strategies for patients in this group of immunodeficiency disorders.

RESUMO

Disease stage and recipient/donor human leukocyte antigen (HLA) matching are important determinants of outcome in transplantation using volunteer-unrelated donors (VUD). Matching for HLA-A, -B, -C, -DRB1, -DQB1 is beneficial, whereas the importance of DPB1 matching is more controversial. The impact of HLA matching status may differ dependent on disease stage. We investigated the outcome according to the degree of HLA matching at 6 loci, in 488 recipients of predominantly T-cell depleted bone marrow VUD transplants for leukaemia. Survival was significantly better in 12/12-matched transplants in those with early leukaemia (5 years: 63 versus 41% in 10/10 matched, P=0.006), but not late stage disease. Conversely, within the HLA-mismatched group (< or =9/10), there was a significant survival advantage to DPB1 mismatching (5 years: 39 versus 21% in DPB1 matched, P=0.008), particularly in late leukaemia (P=0.01), persisting in multivariate analysis (odds ratio 0.478; 95% confidence interval 0.30, 0.75; P=0.001). These novel findings suggest that the best outcome for patients with early leukaemia, with a 10/10-matched donor, is achieved by matching for DPB1. Conversely, our results suggest that in patients receiving an HLA-mismatched graft, the outcome is significantly better if they are also mismatched for DPB1. We recommend validation of these results in independent datasets.

RESUMO

BACKGROUND: Thalassaemia Major (TM) is a serious condition characterized by life-long dependence on blood transfusions and chelation therapy. Our aim was to determine health-related quality of life (HRQOL) in children with TM living in the UK, and the impact of caring for a child receiving National Health Service treatment on family finances. METHODS: This was a cross-sectional assessment of HRQOL in children (n= 22) with TM aged 8-18 years. Children were recruited from three UK Paediatric Haematology and Bone Marrow Transplant centres. Mothers completed measures of their child's HRQOL [PedsQL 4.0 (Measurement Model for the Pediatric Quality of Life Inventory, James W. Varni PhD, PedMetrics, Quantifying the Qualitative SM, Copyright 1998-2009)] and behaviour (Strengths and Difficulties questionnaire), and the impact of caring for the child on family finances. RESULTS: Child behaviour was within the normal range but child HRQOL was significantly lower than population norms. Family financial concerns associated with TM were associated with poorer child HRQOL (P= 0.020). CONCLUSIONS: Thalassaemia Major poses a considerable challenge to child HRQOL, well documented in areas of the world where TM is prevalent. Despite the availability of National Health Service care and financial benefits our study suggests a similar burden in the UK.

RESUMO

Empathy is an essential component of professional nursing practice. In order to empathise appropriately with patients, it is crucial that nurses appreciate, understand and respond to their patients' experience of illness. This study sought to explore the experiences of 16 people with end stage renal disease on haemodialysis therapy in Ireland. A hermeneutical phenomenological methodology was employed incorporating qualitative interviews. The data were analysed using qualitative interpretive analysis. The experience of waiting was significant for the participants in the study. The experience of waiting was constituted by two themes labelled killing time and wasting time. It is suggested that the participants' experience of waiting is reminiscent of Heidegger's existential account of boredom. Moreover, the existential perspective of boredom contained within the participants' accounts is also depicted by Beckett in his play Waiting for Godot. Consequently, the literature of both existential writers is incorporated to provide a more in-depth description of the participants' experience of waiting. It is hoped that the insights provided in this paper will enable practitioners to gain a new awareness and understanding of patients' experiences of end stage renal disease and haemodialysis therapy. This would subsequently enable these professionals to empathise more effectively with their patients' situation and respond more appropriately to their care needs.

RESUMO

The tyrosine kinase ZAP-70 plays a critical role in signal transduction in T cells and NK cells but has limited expression in primary human B cells. ZAP-70 is, however, expressed in adult B cell chronic lymphocytic leukemia where it correlates with a poor prognosis. We wished to determine if ZAP-70 is also expressed in pediatric B cell malignancy. A quantitative PCR assay for ZAP-70 expression was established and ZAP-70 expression in a range of human B cell lines was compared with expression in the Jurkat T cell line. ZAP-70 expression was then determined in bone marrow lymphoblasts obtained from 12 patients with pre-B cell acute lymphoblastic leukemia (ALL). ZAP-70 expression was not detected in mature B cell lines but was detected in pre-B cell lines at a level comparable to that seen in T cells. ZAP-70 expression was strongly expressed in nine of the 12 cases of primary pre-B cell lymphoblastic leukemia. The T cell-associated protein kinase ZAP-70 is highly expressed in pre-B lineage cells and most cases of pre-B acute lymphoblastic leukemia. ZAP-70 expression may hold prognostic value for pre-B ALL and raises the prospect of a novel therapeutic target.

RESUMO

Congenital erythropoietic porphyria (CEP, Günther's disease) has a very variable phenotype. In the more severely affected, bone marrow transplantation (BMT) is potentially curative, but is not without risks. We describe a 7-year-old girl with CEP characterized by severe photosensitivity but only mild anaemia, in whom the difficult decision to proceed with allogeneic BMT was made after discussion in a multidisciplinary team. She has shown successful engraftment, accompanied by biochemical and clinical resolution of her metabolic disease. She remains well 3 years later, the oldest patient with CEP receiving BMT to survive beyond 12 months. However, she has experienced significant morbidity including florid cutaneous graft-versus-host disease with postinflammatory hypopigmentation. Her case is important in highlighting the delay in diagnosis not uncommon in this condition and the complex decision-making process involved in proceeding with BMT.

RESUMO

We conducted a retrospective study to compare outcome in Caucasians and non-Caucasians undergoing standard sibling allogeneic SCT. End points of the study were to compare graft-versus-host disease (GvHD) occurrence and transplant-related mortality (TRM). There were 251 patients, 43 non-Caucasian and 208 Caucasian. A higher proportion of non-Caucasian patients developed acute GvHD (aGvHD) grade 2 or greater as compared to the Caucasian group (48 vs 26%, respectively) P = 0.02. With a median follow-up of 27 months, 26% (11/43) of non-Caucasians and 14% (29/208) of Caucasian patients had died from TRM, which accounted for 55% of all deaths in the non-Caucasian group compared to 33% in Caucasians, P = 0.02. Overall survival 12 months post transplant was 64 vs 69% in the non-Caucasian and Caucasian groups, respectively (P = 0.43). Although there were higher numbers of CMV-positive patients in the non-Caucasian group, there were no deaths from CMV reactivation in this subgroup. We conclude that there is increased TRM and aGvHD following standard sibling allograft in the non-Caucasian population and this could be due to either differences in tumour biology or extrinsic factors such as socio-economic factors, nutritional status, post transplant care or presenting with late stage disease.

RESUMO

Seven children with Fanconi anaemia (FA) (five female, two male), who had not undergone transformation, received nine haemopoietic stem cell transplantation (HSCT) between 2000 and 2004. Conditioning regimen was: fludarabine 25-30 mg/m2/day for 5 days, antilymphocyte globulin 12.5 mg/kg/day for 3 days and cyclophosphamide 5-7.5 mg/kg/day for 4 days. Radiation was not used. One male patient who had multiple HSCT and one female who was retransplanted, received slightly different conditioning regimens. Four patients received fully matched unrelated umbilical cord blood (UCB), two matched unrelated peripheral blood stem cell (PBSC) grafts, and three haploidentical T-cell-depleted (TCD) PBSC grafts. None of the patients had any significant conditioning-related toxicity or severe infections. All engrafted within 2-3 weeks. One patient rejected her first HSCT after 10 weeks and had a second successful transplant from the same donor. One male patient rejected his TCD haploidentical HSCT from his mother, and subsequently had a successful fully matched unrelated UCB transplant. Rejection rate was 22%. Acute and chronic graft-versus-host disease (GVHD) was seen in 77 and 22% patients. In all, 57% patients developed autoimmune complications, all of which have resolved. All patients are well with stable or full donor chimerism after a median follow-up of 37 months (range 13-54).

RESUMO

Three neonates with glucose-6-phosphate dehydrogenase (G6PD) deficiency are described. All three patients suffered an episode of massive acute haemolysis, in the absence of blood group incompatibilities, infection, or ingestion of oxidising agents known to trigger haemolysis. One patient died, but the other two survived after an exchange transfusion. This highlights that G6PD deficiency in the neonatal period may present with severe anaemia in association with hyperbilirubinaemia.

RESUMO

Aplastic anaemia is a rare but serious disorder with a high morbidity and mortality rate. The causes of aplastic anaemia are, for the most part, unknown. We report on the hypothesis that aplastic anaemia may be caused by occupational and/or environmental exposures to certain chemicals. The UK Aplastic Anaemia Study was an interview-based case-control study covering the whole of Great Britain. Those patients diagnosed between 1 July 1993 and 20 October 1997, aged < or =75 years and born and diagnosed in the UK were eligible for the study. Two hundred eligible cases of aplastic anaemia were compared with 387 age- and sex-matched controls. A number of occupational exposures showed increases in risk. In a multivariate model of these exposures the odds ratios (ORs) for solvents/degreasing agents, pesticides and radiation were >2 and statistically significant. Reported chemical treatment of houses within 5 years of diagnosis had a significantly raised risk for adults [OR = 2.51, 95% confidence interval (CI) 1.02-12.01], particularly for woodworm treatment (OR = 5.1, 95% CI 1.5-17.4). This study identified significant risks associated with self-reported exposure to solvents, radiation and pesticides in the workplace. Self-reported chemical treatment of houses was also associated with an increased risk of developing aplastic anaemia, in keeping with previous literature.

RESUMO

Twenty-one paediatric patients (11 males and 10 females) received a CD34-selected partially matched related donor transplant for malignant (16 cases) and non-malignant conditions (five cases). The average cell dose was 11.13 x 10(6)/kg. Fifteen of 16 patients with malignant conditions and one with non-malignant disease received total body irradiation plus cyclophosphamide. Three of 5 patients with non-malignant conditions and one with leukaemia, received busulphan plus cyclophosphamide. One patient with Fanconi anaemia received 100 mg/kg of cyclophosphamide. Fludarabine (25 mg/m(2)/day for 5 days) was administered prior to all these regimens. Additionally, anti-lymphocyte gamma-globulin (12.5 mg/kg/day) was administered from day -2 to day +2. Three (15%) patients failed to achieve complete chimaerism (CC). These patients received a second cell infusion. Two of them achieved CC. In the third patient, the percentage of donor cells was increased. The likelihood for engraftment was not related to the cell dose received. Acute graft-versus-host disease (GVHD) occurred in nine patients but only one developed GVHD >grade II. Eight patients developed active viral infections, which resolved after treatment. Patients receiving cell doses higher than our average had a significantly faster CD3 and CD4 cell recovery and experienced a lower incidence of viral infections. After 480 +/- 255 days of median follow-up, 16/21 patients are alive and well and have CC. Three patients died of leukaemic relapse and a fourth from progression of his disease (adreno-leuko-dystrophy). We conclude that partially matched related donors are a feasible source of haemopoietic progenitor cells for transplantation for patients without matched familial or unrelated donors.

RESUMO

The pathogenesis of pediatric B-precursor acute lymphoblastic leukemia is largely unknown, and even with nonrandom chromosomal translocations present, the precise order of clonal molecular events is undefined. We developed an in vitro system using cytokines interleukin (IL)-3, IL-7, IL-10, and FMS-like tyrosine kinase 3 ligand with CD40 ligand-expressing fibroblasts to obtain single blast colonies from which clonal immunoglobulin heavy chain (IgH), T-cell receptor delta gene rearrangements, and, in t(12;21)-positive cases, TEL-AML1 fusion transcripts could be simultaneously PCR amplified. The proliferation of early tumor progenitors increased subclone detection enabling us, in seven diagnostic samples, to determine the stage of differentiation at which each leukemia occurred. Four were derived from the stage before initiation of IgH rearrangement, one during recombination of variable, joining, and diversity segments of the heavy chain gene VDJ(H), and two after completion of IgH rearrangement. Furthermore, analysis of a t(12;21)-positive leukemia with unusually late onset, identified both TEL-AML1-positive and -negative colonies carrying a clonal T-cell receptor delta rearrangement, inferring the presence of clonal expansion before the occurrence of the t(12;21). In contrast, in a typical, early onset t(12;21)-positive leukemia, the t(12;21) appeared to be the first clonal event. In both leukemias, the t(12;21) occurred before recombination of variable, joining and diversity segments of the heavy chain gene VDJ.

RESUMO

Gambling research has contributed much to our understanding of the effects of gambling on families, yet we have only the most cursory understanding of the child's perspective on what it is like to grow up in such a family. The aim of this qualitative study was to gain a deeper understanding of the experiences of Australian children who live in families where a parent or caregiver has a serious gambling problem by exploring the perspectives and understandings of the children and young people themselves. This paper reports a central finding, the experience of 'Pervasive Loss,' from our interviews with 15 young people, 11 males and 4 females, aged between 7 and 18 years. Their sense of loss encompassed both physical and existential aspects of the child's life, including their parent(s), relationships, trust, security, sense of home, and material goods. The dimensions of this experience of pervasive loss are explored from the child's perspective. Children living in families where gambling is a problem experience threats to their overall well-being to the extent that parental problem gambling must now considered to be a significant child health as well as social problem.

RESUMO

Problem gambling is becoming an increasingly widespread and damaging social and health problem. As opportunities for gambling become more accessible, especially through lotteries and electronic gaming machines, it is likely that more people will develop serious gambling problems. Given the worldwide increasing spending on gambling activities and the increasing number of problem gamblers, it is unfortunate but likely that the children who grow up in problem gambling families will become an important area of concern for child health and social workers. Considerable research has been undertaken into problem gambling and the adult problem gambler, but within the gambling and child health literature there is almost no recognition of the experiences of children who live in problem-gambling families. Drawing on the findings of the landmark Productivity Commission Report, this review explores the marked increase in gambling and its social effects, especially from the Australian perspective. The damaging social effects of problem gambling on families and children are reviewed and the comparative invisibility of children and young people in such research is discussed. The pervasive influence of developmentalism is critiqued and highlighted in relation to the exclusion of children's perspectives from our research understandings. The review concludes by proposing that adoption of some of the emerging 'new paradigm' approaches to childhood and children's experiences could markedly enhance our understandings of the lives and experiences of this significant group of children and young people.

RESUMO

We have prospectively assessed the relative contribution of host and donor to haemopoiesis following stem cell transplantation (SCT) in children with beta-thalassaemia major (n = 35), using karyotype analysis or Southern blot/polymerase chain reaction analysis of variable number tandem repeats on genomic DNA from peripheral blood. Early haemopoiesis was fully donor in origin in 24 out of 35 cases and remained so throughout the post-transplant course in all but one patient, who evolved to stable mixed chimaerism. The remaining 11 cases (31%) initially showed mixed chimaerism: four of these rejected, one eventually eradicated host haemopoiesis to become fully donor haemopoietic, and the remaining six had persistent mixed chimaerism, with 5--38% host haemopoiesis. The risk of graft rejection was high when > 15% host haemopoiesis was present at 3 months post transplant: four out of six such patients rejected their grafts; conversely, zero out of 29 patients with < 15% host haemopoiesis at 3 months rejected (P < 0.0001). There was a higher incidence of significant acute and chronic graft-versus-host disease in patients with full donor chimaerism. These studies confirm that the mixed chimaeric state is common following SCT for thalassaemia, often persists (with up to 4 years follow-up) and is compatible with long-term cure. Analysis of chimaerism in patients undergoing SCT for beta-thalassaemia enables monitoring of engraftment in the early post-transplant period, provides insight into the biology of engraftment and may be useful in identifying patients at high risk of rejection.
