Translation to practice: a randomised controlled study of an evidenced based booklet targeted at breast care nurses in the United Kingdom

BACKGROUND: In the United Kingdom (UK), it was documented that a problem of knowledge transfer existed within the speciality of breast-cancer care, thus depriving patients of receiving optimal care. Despite increasingly robust research evidence indicating recommendation of whole body exercise for people affected by breast cancer, commensurate changes to practice were not noted amongst breast-care nurses (BCNs). AIM: To evaluate the effect of a targeted booklet, Exercise and Breast Cancer: A Booklet for Breast-Care Nurses, on changes in knowledge, reported practice, and attitudes of BCNs in the UK. METHOD: A prospective, experimental approach was used for designing a pre- and post-test randomised controlled study. Comparisons of knowledge, reported practice, and attitudes based on responses to a questionnaire were made at two time-points in two groups of BCNs (control and experimental). The unit of randomisation and analysis was hospital clusters of BCNs. The sample comprised 92 nurses from 62 hospitals. Analysis consisted of descriptive statistics and clustered regression techniques: clustered logistic regression for knowledge items, clustered linear regression for knowledge scores, ologit for attitude and reported practice items, and clustered multiple regression for paired and multiple variable analysis. RESULTS: A statistically significant increase in knowledge and changes in reported practice and attitudes were found. Robust variables affecting knowledge acquisition were: promotion of health, promotion of exercise, and understanding how exercise can reduce cancer-related fatigue. DISCUSSION: The study has shown that evidence-based printed material, such as an information booklet, can be used as an effective research dissemination method when developed for needs, values, and context of a target audience. CONCLUSIONS: This practical approach to research dissemination could be replicated and applied to other groups of nurses.</p

Geographical and temporal distribution of SARS-CoV-2 clades in the WHO European Region, January to June 2020

We show the distribution of SARS-CoV-2 genetic clades over time and between countries and outline potential genomic surveillance objectives. We applied three available genomic nomenclature systems for SARS-CoV-2 to all sequence data from the WHO European Region available during the COVID-19 pandemic until 10 July 2020. We highlight the importance of real-time sequencing and data dissemination in a pandemic situation. We provide a comparison of the nomenclatures and lay a foundation for future European genomic surveillance of SARS-CoV-2.Peer reviewe

Identifying gender differences in the independent effects of personality and psychological well-being on two broad affect components of subjective well-being

Subjective Well-Being (SWB) is defined in terms of positive and negative affect whilst Psychological Well-Being (PWB) reflects self-referent attitudes of mastery and self-acceptance. Whilst both SWB and PWB are associated with personality, concurrent analysis is limited. This study (n = 679) reports on a teacher sample in which personality, SWB and PWB were measured. Results indicated moderate correlations between variables. Hierarchical regression controlled for personality and identified PWB as a significant predictor of SWB. Separate predictors of negative and positive affect support the need to assess both SWB affective components. As the most significant predictor of positive affect the inclusion of PWB is needed in future well-being research

ADAMTS-13 assays in thrombotic thrombocytopenic purpura

ADAMTS-13, the thirteenth member of the ADAMTS (A Disintegrin And Metalloprotease with Thrombo-Spondin 1 repeats) family, is the plasma metalloprotease responsible for regulating the multimeric structure of VWF. In congenital or acquired deficiency it is actively involved in the pathophysiology of thrombotic thrombocytopenic purpura (TTP), a rare but life threatening disease characterized by microangiopathic haemolytic anaemia and consumptive thrombocytopenia leading to disseminated microvascular thrombosis and variable signs and symptoms of organ ischemia and damage. In the last few years, a number of in house and commercial laboratory assays for ADAMTS-13 and its autoantibodies have been developed. The features and clinical utility of ADAMTS-13 assays are summarized in this revie

The effect of prion reduction in solvent/detergent treated plasma on haemostatic variables

BACKGROUND: Octapharma PPGmbH has recently modified its manufacturing process for solvent/detergent-treated plasma to incorporate a prion reduction step, in which a 3 log reduction has been demonstrated. The current study was undertaken to assess the impact of this procedure on haemostatic variables in the new product OctaplasLG in comparison with standard Octaplas. METHODS: Production batches of standard Octaplas (n=4) and OctaplasLG (n=16) were assessed for levels of coagulation factors, physiological protease inhibitors, markers of activation and procoagulant microparticles. Global haemostasis was assessed by a thrombin generation test (TGT) and rotational thromboelastometry (ROTEM). RESULTS: Mean levels of factors: II, V, VII, IX, X, XI, XII and XIII, VWF:Ag, antithrombin, protein C and free protein S were all >75 u/dl. ADAMTS-13 activity levels were normal. Factor VIII and VWF:RCo were >55 u/dl. TGT and ROTEM were similar in both preparations, and microparticles were present at negligible levels. Two units of OctaplasLG had slightly elevated levels of Prothrombin Fragments 1+2, but D-Dimer and thrombin-antithrombin complexes were normal in all batches. CONCLUSION: These studies indicate that the affinity chromatography procedure used in OctaplasLG does not appear to adversely affect the proven haemostatic quality of Octaplas, while offering a selective reduction in the concentration of pathological prion protein

Mapping of monilethrix to the type II keratin gene cluster at chromosome 12q13 in three new families, including one with variable expressivity

Monilethrix is an autosomal dominant disorder chiefly affecting hair. The degree of hair dystrophy is highly variable, as is the presence of additional features, such as follicular keratoses. In three British families of monilethrix, linkage has recently been reported to the type II keratin gene cluster at chromosome 12q13, and it has been suggested that the disease is due to a defect in the hard keratins of hair and nail. If monilethrix is a keratin disorder, we would predict that some pedigrees might map to the type I keratin gene cluster on 17q where hard keratin genes are also found. We have now studied clinically and by linkage analysis three new and unrelated pedigrees from England, Scotland and Spain, the first of which showed a variant phenotype. In this family the disease was expressed in four of 12 cases only as a follicular keratosis of the neck, elbows and knees, and without clinical or historical evidence of hair anomalies: non-penetrance in an obligate carrier was also observed. In all three families, we have established linkage to a series of microsatellite markers at the type II locus at 12q13 (Zmax=6.34 at 0=0.00 for D12S368) and have excluded linkage from the type I keratin gene cluster on 17q. It remains probable that monilethrix is a disorder of hard keratins, but at present there is no evidence that it is due to defects in type I keratins
