Trauma-informed care: recognizing and resisting re-traumatization in health care.

Trauma is often viewed as an individual or interpersonal issue. This paper expands the definition of trauma to include the impact collective and structural elements on health and well-being. The need for a trauma-informed response is demonstrated, with instruction as to how to implement this type of care in order to resist re-traumatization. Three examples from healthcare settings across the nation are provided, to demonstrate the ways in which organizations are bringing forward this patient-centered, trauma-informed approach to care.

Violence Is One Small Part of Childhood Trauma. So Why Do We Tend to Focus on It Alone?

Many people and organizations focus on preventing violence with the belief that if our society can stop violence against chil- dren, then most childhood trauma will be eradicated. How- ever, research that has emerged over the last 20 years clearly shows that focusing primarily on violence prevention - physical and sexual abuse, in particular - doesn't eliminate the trauma that children experience, and it won't even prevent further violence.

Cost-effectiveness of a modified two-step algorithm using a combined glutamate dehydrogenase/toxin enzyme immunoassay and real-time PCR for the diagnosis of Clostridium difficile infection.

The analytical performance and cost-effectiveness of the Wampole Toxin A/B EIA, the C. Diff. Quik Chek Complete (CdQCC) (a combined glutamate dehydrogenase antigen/toxin enzyme immunoassay), two RT-PCR assays (Progastro Cd and BD GeneOhm) and a modified two-step algorithm using the CdQCC reflexed to RT-PCR for indeterminate results were compared. The sensitivity of the Wampole Toxin A/B EIA, CdQCC (GDH antigen), BD GeneOhm and Progastro Cd RT-PCR were 85.4%, 95.8%, 100% and 93.8%, respectively. The algorithm provided rapid results for 86% of specimens and the remaining indeterminate results were resolved by RT-PCR, offering the best balance of sensitivity and cost savings per test (algorithm ∼US$13.50/test versus upfront RT-PCR ∼US$26.00/test).

Serum selenium concentration at diagnosis and outcome in patients with haematological malignancies.

We have previously reported presentation serum selenium level to be predictive of outcome in diffuse large B-cell lymphoma. This has now been studied in a further 430 patients, 163 with acute myeloid leukaemia (AML), 156 with Hodgkin Lymphoma (HL), and 111 with Follicular Lymphoma (FL). Serum selenium was below the UK normal reference range in 45% of patients, and correlated with serum albumin (r=0·24-0·46, P<0·001-0·003) in all tumour types. Independent predictors of presentation selenium were; French-American-British subtype and albumin (P<0·001 for both) in AML, haemoglobin (P=0·002) and B-symptoms (P=0·01) in HL, and albumin (P<0·001) in FL. In AML and HL, response to first line therapy was lower in patients with low serum selenium, but selenium was no longer predictive of response when other variables were entered into a multivariate model. Low selenium was also associated with a worse overall survival in FL [Hazard Ratio (HR) 2·3, 95% confidence interval (CI) 1·4, 4·0] and a trend to a worse overall survival in AML (HR 1·43, 95% CI 0·96, 2·13) by univariate Cox regression analysis, but not by multivariate analysis. In conclusion, low serum selenium is associated with a worse outcome in patients with haematological malignancies, but is not independently predictive, suggesting that it reflects other factors.

Exudate, infection and patient quality of life.

Efficient and cost-effective management of excessive wound exudate continues to present unique challenges to nurses. Accurate patient and wound assessment is essential to inform the treatment and selection of suitable dressings. The wide range of modern wound management products should be sufficient to meet the needs of every wound type at all phases of healing, and as circumstances change. However, there are still situations in which nurses are having to change dressings a number of times in 24 hours to prevent maceration (i.e. the softening and whitening of skin that is kept constantly wet), soiling, and the potential for cross-infection. There is no easy solution to the problem, but as nurses become more knowledgeable about identifying and managing the causes of excessive exudate, the available management options, and, as dressing materials become more sophisticated, practice should improve in this area.

Use of Hydrofilm and Hydrofilm Plus in the community: an assessment.

The aim of this article was to critically examine the case for using film dressings with a particular emphasis on two dressing manufactured by Paul Hartmann Ltd: Hydrofilm and Hydrofilm Plus. The authors undertook a review of the current published evidence and present four case studies where Hydrofilm and Hydrofilm Plus were used in the community setting.

Plasma cell myeloma diagnosed in pregnancy.

Plasma cell myeloma (PCM) is an essentially incurable neoplastic disorder of terminally differentiated B cells. The neoplastic clone usually secretes a monoclonal protein in the serum or urine (the 'M band'). About 20% of PCM secrete light chains only, which are detectable in the urine as Bence Jones protein. The clinical picture is one of bone marrow failure, due to infiltration of the marrow by malignant plasma cells; renal failure due to damage to renal tubules by the excess light chains and pain due to lytic lesions of the bones. The outcome remains poor with median survival of 5 years.

Rapid antigen tests for diagnosis of pandemic (Swine) influenza A/H1N1.

We found that the sensitivities of 3 rapid influenza antigen tests for pandemic influenza A/H1N1 virus were low to moderate: BD Directigen EZ Flu A+B test (Becton Dickinson), 46.7%; BinaxNOW Influenza A&B (Inverness Medical), 38.3%; and QuickVue Influenza A+B Test (Quidel), 53.3%. A patient with influenza-like illness who has a negative rapid antigen test result should undergo further testing using reverse-transcription polymerase chain reaction.

Patterns of recruitment into acute myeloid leukaemia (AML) 15 and outcome for young patients with AML at a single referral centre.

This study assessed the recruitment to an acute myeloid leukaemia (AML) trial (AML15) in a single centre, evaluated whether outcome was influenced by trial entry and whether the trial population could be considered representative of all AML patients by retrospective comparison of patient characteristics, trial entry and outcome for 81 consecutive patients (<60 years). All patients were considered for trial entry, however the trial was not offered to 12 (15%) patients. These patients had a worse outcome than the 69 (85%) patients that were invited to participate (P = 0.04). Sixteen patients (23%) invited to participate in the trial declined and were treated on equivalent protocols. These patients had a similar outcome to those who accepted entry into the trial (P = 0.2). These results suggested that physicians exert a selection bias when evaluating patients for trial entry. Thus the overall survival estimates generated from large phase III trials may indicate that the outcome for patients with AML is better than the outcome experienced in the 'real' world. Furthermore, patients who are considered appropriate for randomization into a trial, but decline entry, experience a similar outcome to those treated on trial when treated in an equivalent manner.

Five new pedigrees with inherited RUNX1 mutations causing familial platelet disorder with propensity to myeloid malignancy.

Familial platelet disorder with propensity to myeloid malignancy (FPD/AML) is an autosomal dominant syndrome characterized by platelet abnormalities and a predisposition to myelodysplasia (MDS) and/or acute myeloid leukemia (AML). The disorder, caused by inherited mutations in RUNX1, is uncommon with only 14 pedigrees reported. We screened 10 families with a history of more than one first degree relative with MDS/AML for inherited mutations in RUNX1. Germ- line RUNX1 mutations were identified in 5 pedigrees with a 3:2 predominance of N-terminal mutations. Several affected members had normal platelet counts or platelet function, features not previously reported in FPD/AML. The median incidence of MDS/AML among carriers of RUNX1 mutation was 35%. Individual treatments varied but included hematopoietic stem cell transplantation from siblings before recognition of the inherited leukemogenic mutation. Transplantation was associated with a high incidence of complications including early relapse, failure of engraftment, and posttransplantation lymphoproliferative disorder. Given the small size of modern families and the clinical heterogeneity of this syndrome, the diagnosis of FPD/AML could be easily overlooked and may be more prevalent than previously recognized. Therefore, it would appear prudent to screen young patients with MDS/AML for RUNX1 mutation, before consideration of sibling hematopoietic stem cell transplantation.

Mutation of the Wilms' tumor 1 gene is a poor prognostic factor associated with chemotherapy resistance in normal karyotype acute myeloid leukemia: the United Kingdom Medical Research Council Adult Leukaemia Working Party.

PURPOSE: To determine the clinical relevance of Wilms' tumor 1 (WT1) gene mutations in acute myeloid leukemia (AML) with normal karyotype (NK). PATIENTS AND METHODS: Exons 7 and 9 of WT1 were screened in samples from 470 young adult NK AMLs using a combination of direct sequencing and high-resolution capillary electrophoresis. RESULTS: Overall, 51 mutations were detected in 47 cases (10%): 46 frameshift mutations with insertion/deletion of one to 28 base pairs in exon 7 (n = 45) or exon 9 (n = 1), with a median mutant level of 45% (range, 8% to 86%), and five substitutions in exon 9: D396N (n = 3), H397Y (n = 1) and H397Q (n = 1). Patients with WT1 mutations had an inferior response to induction chemotherapy compared with wild-type cases (complete remission rate, 79% v 90%, odds ratio [OR] = 3.02; 95% CI, 1.17 to 7.82; P = .02), a higher rate of resistant disease (15% v 4%; OR = 9.33; 95% CI, 2.38 to 36.6; P = .001), an increased cumulative incidence of relapse (67% v 43%, hazard ratio [HR] = 3.02; 95% CI, 1.69 to 5.38; P = .0008), with a reduction in both relapse-free survival (22% v 44%; HR = 2.16; 95% CI, 1.32 to 3.55; P = .005) and overall survival (26% v 47%; HR = 1.91; 95% CI, 1.23 to 2.95; P = .007) at 5 years. In multivariate analysis, which included FLT3 internal tandem duplication and NPM1 mutation status, the presence of a WT1 mutation remained an independent adverse prognostic factor. CONCLUSION: WT1 mutations are a negative prognostic indicator in NK AML and may be suitable for the development of targeted therapy.

Microdeletions are a general feature of adult and adolescent acute lymphoblastic leukemia: Unexpected similarities with pediatric disease.

We present here a genome-wide map of abnormalities found in diagnostic samples from 45 adults and adolescents with acute lymphoblastic leukemia (ALL). A 500K SNP array analysis uncovered frequent genetic abnormalities, with cryptic deletions constituting half of the detected changes, implying that microdeletions are a characteristic feature of this malignancy. Importantly, the pattern of deletions resembled that recently reported in pediatric ALL, suggesting that adult, adolescent, and childhood cases may be more similar on the genetic level than previously thought. Thus, 70% of the cases displayed deletion of one or more of the CDKN2A, PAX5, IKZF1, ETV6, RB1, and EBF1 genes. Furthermore, several genes not previously implicated in the pathogenesis of ALL were identified as possible recurrent targets of deletion. In total, the SNP array analysis identified 367 genetic abnormalities not corresponding to known copy number polymorphisms, with all but two cases (96%) displaying at least one cryptic change. The resolution level of this SNP array study is the highest used to date to investigate a malignant hematologic disorder. Our findings provide insights into the leukemogenic process and may be clinically important in adult and adolescent ALL. Most importantly, we report that microdeletions of key genes appear to be a common, characteristic feature of ALL that is shared among different clinical, morphological, and cytogenetic subgroups.

The impact of the European Environment and Health Process on UK environment and health policy, plans and practice: what difference has it made?

The European Environment and Health Process (EEHP), led by the World Health Organization (WHO) Regional Office for Europe, aims to support WHO Member States as they plan and implement national and international environment and health policies. An evaluation of the impact of the EEHP in the UK was conducted in preparation for the fourth Ministerial Conference on Environment and Health in Budapest, 2004. The evaluation identified a number of impacts and influences of the EEHP. This concluded that the process had only a marginal direct influence on policy within the UK. However, it was also concluded that the process had resulted in several indirect influences, including better cooperation between government departments, greater awareness of environment and health issues from an international perspective, and a higher political profile of environment and health issues. A few outcomes of the EEHP also appear to have been taken into account in some national and local policy documents. The National Environmental Health Action Plan, which was produced as a direct result of the EEHP, appears to have had little direct impact in the UK, probably because of the lack of an implementation process and indicators, and because it was superseded by other policy initiatives relatively soon after publication. A need for better coordination and promotion of the EEHP amongst stakeholders responsible for environment and health policy areas was also identified.
