RESUMO
BACKGROUND: Implementation of reflective practice groups in psychiatric and mental health contexts might improve the quality of care through promoting self-awareness, clinical insight, and facilitating stress management and team building. There is a need for valid and reliable instruments to test the outcomes of reflective practice groups in the mental health context. This study aimed to test the validity and reliability of the Swedish version of the Clinical Supervision Evaluation Questionnaire. METHODS: The instrument was translated from English to Swedish using a translation and back-translation procedure. Data for the calculation of content validity was collected from an expert group. Data for the reliability analysis was collected from rehabilitation assistants and ward managers participating in reflective practice groups (n = 20). Content validity was measured by computing a content validity index. Construct validity was assessed by calculating the corrected item-total correlation statistics. Reliability was evaluated by analysing the Cronbach's alpha coefficient, the intraclass correlation coefficient and inter-item correlations. RESULTS: The content validity index for the scale as a whole was 0.94. Item-total correlations ranged between 0.23 and 0.81, and deletion of an item did not notably improve Cronbach's alpha. Cronbach's alpha for the scale was 0.89. The intraclass correlation coefficient for single measures was 0.35. The mean inter-item correlation was .37. CONCLUSION: The Swedish version of the Supervision Evaluation Questionnaire has a degree of reliability and validity that is comparable to the original version in English, indicating that it can be used as an assessment of reflective practice groups in the mental health context.
RESUMO
OBJECTIVES: Oral health in nursing homes for elderly is often unsatisfactory, and oral health education to nursing staff has not shown sufficient results why there is need for novel approaches. The aim of the study was to trial a new oral healthcare educational programme and to evaluate the effects on residents' oral health. In addition, attitudes among the nursing staff in the intervention nursing home were explored. METHODS: In a controlled clinical trial, two comparable nursing homes were randomly assigned for intervention or control. Interventions included weekly theoretical and hands-on guidance from dental hygienists on oral hygiene procedures and discussions on oral care routines. The residents' oral health, measured by the Revised Oral Assessment Guide (ROAG), dental plaque and gingival bleeding were evaluated at baseline and after 3 months. Attitudes among the staff to oral health care were measured at the intervention nursing home. RESULTS: Revised Oral Assessment Guide gums and lips scores showed a tendency to decrease in the intervention group, but remained high in the control group. Plaque levels improved significantly after intervention, and a trend towards less gingival bleeding was observed. The intervention nursing staff seemed to be more aware of their own limitations concerning oral health care after intervention and valued more frequent contact with dental services to a greater extent. CONCLUSIONS: The oral healthcare situation for elderly people today is so complex that theoretical education at the group level regarding different aspects of oral health is not sufficient. Individual hands-on guidance by dental hygienists on a regular basis in everyday care may be a new approach.

Haematophagous mites were collected from the vent region and plumage of chickens in six hobby flocks of ornamental breeds in Sweden, one of which included turkeys. Soiled vent skin and feathers, dermatitis, hyperkeratosis, skin necroses and ulcers were observed in 12 necropsied birds from two of the flocks. The mites were identified as the northern fowl mite Ornithonyssus sylviarum (Mesostigmata: Macronyssidae). This was supported by sequence analysis of a 642-bp region in the mitochondrial cytochrome oxidase subunit 1 (COI) gene (COI) in mites collected from five flocks, which showed 97-99% sequence similarity to O. sylviarum by blast analysis. Pairwise sequence comparisons revealed nucleotide variations in the range of 0-2.8%, whereas amino acid sequences were highly conserved. This paper represents one of very few records of O. sylviarum in European poultry, and is the first to report COI sequence data for O. sylviarum from poultry in Europe.

B10.RIII mice develop chronic and relapsing experimental autoimmune encephalomyelitis (EAE) after immunization with the myelin basic protein (MBP) peptide 89-101. The disease is associated with the major histocompatibility complex (MHC) (eae1). We have now investigated the importance of non-MHC regions for the EAE susceptibility in a cross between RIIIS/J and B10.RIII mice which share the MHC region but differ in disease susceptibility. Linkage analysis using microsatellite markers spanning the genome identified a region (eae2) on chromosome 15 which showed linkage to disease (P = 0.0002). Our data also suggest linkage to a second region (eae3) on chromosome 3 (P = 0.0024), and provide evidence for locus interactions between eae2 and eae3. These results provide clues to the genetic basis of multiple sclerosis.

INTRODUCTION: The temporary trauma teams in trauma alerts consist of a diverse group of unique professionals requiring interprofessional collaboration and coordination to achieve efficient, high-quality care. The uncertain situation and complex care environment impose high demands on team dynamics such as individual attitudes and team behaviours. Within interprofessional teams, interaction and coordination reflect the collective success of collaboration and the achievement of goals. Interactions with radiographers have increased in trauma teams given computed tomography's prominent role in providing crucial knowledge for decision-making in trauma care. This study aimed to explore radiographers' experiences of interprofessional collaboration during trauma alerts. METHOD: The study was designed with focus group methodology, including 17 radiographers participating in five focus groups, analysed with an inductive focus group analysis. RESULTS: An overarching theme, "On the edge of decision-making", emerged along with three sub-themes: "Feeling included requires acknowledgement", "Exclusion precludes shared knowledge", and "Experience and mutual awareness facilitate team interaction". CONCLUSIONS: Interprofessional collaboration from the radiographer's perspective within trauma teams requires a sense of inclusion and the ability to interact with the team. Exclusion from vital decision-making obstructs radiographers' comprehension of situations and thereby the interdependence in interprofessional collaboration. IMPLICATIONS FOR PRACTICE: Common platforms are needed for knowledge sharing and team practices, including radiographers' areas of responsibility and relational coordination to foster interprofessional relationships. Through these means interdependence through awareness and shared knowledge can be facilitated on trauma teams.

Internet-based treatment (IBT) for provoked vulvodynia (PVD) may reduce pain during intercourse and increases pain acceptance. However, a there is still a knowledge gap regarding the cost-effectiveness of IBT for PVD. The aim of this study was to perform a health economic evaluation of guided internet-based intervention for PVD as an addition to standard treatment. The sample consisted of 99 women with a PVD diagnosis. Healthcare related costs, health-related quality of life, and quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratio (ICER) were analyzed. After the IBT, the intervention group had fewer visits to a midwife than the control group (p = 0.03), but no between-group differences were found for visits to other professionals, treatment length, health-related quality of life, QALYs, and costs for treatment. It was estimated a cost of 260.77 for a clinical meaningful change in pain acceptance. Internet-based treatment as add-on to clinical treatment may lower number of visits to a healthcare.

In an academic programme, completion of a postgraduate degree project could be a significant means of promoting student learning in evidence- and experience-based practice. In specialist nursing education, which through the European Bologna process would be raised to the master's level, there is no tradition of including a postgraduate degree project. The aim was to develop a didactic model for specialist nursing students' postgraduate degree projects within the second cycle of higher education (master's level) and with a specific focus on nurturing shared involvement between universities and healthcare settings. This study embodies a participatory action research and theory-generating design founded on empirically practical try-outs. The 3-year project included five Swedish universities and related healthcare settings. A series of activities was performed and a number of data sources secured. Constant comparative analysis was applied. A didactic model is proposed for postgraduate degree projects in specialist nursing education aimed at nurturing shared involvement between universities and healthcare settings. The focus of the model is student learning in order to prepare the students for participation as specialist nurses in clinical knowledge development. The model is developed for the specialist nursing education, but it is general and could be applicable to various education programmes.

A critical event in an immune response is the T cell recognition of peptides bound to major histocompatibility complex (MHC) molecules on the surface of an antigen presenting cell (APC). Although the majority of eukaryotic proteins are glycosylated, it has not yet been shown that T cell recognition of such proteins involves recognition of the bound carbohydrates. Type II collagen (CII), the major protein constituent of joint cartilage, is posttranslationally modified by hydroxylation and glycosylation of lysines. In this report we show that posttranslational modifications of the immunodominant peptide CII(256-270) generate a structural determinant that is distinct from the determinant represented by the corresponding synthetic peptide. Elimination of carbohydrates, present on CII, by two different biochemical methods revealed that the carbohydrates, O-linked to the hydroxylysines within the CII(256-270) determinant, were crucial for the reactivity towards the posttranslationally modified peptide. Furthermore, a T cell hybridoma specific for the glycosylated determinant was stimulated by tryptic CII-peptides presented by fixed APCs, thus showing that the carbohydrates are involved in the trimolecular complex T cell receptor/peptide/MHC. Finally, the importance of the bound carbohydrates for the arthritogenicity of CII was investigated by comparing the development of arthritis after immunization with carbohydrate-depleted and glycosylated CII, respectively. Incidence, time of onset, and severity of the disease were significantly affected by the elimination of carbohydrates, whereas no significant difference in anti-CII antibody titers was seen.

BACKGROUND: Autoantibodies to cyclic citrullinated peptides (anti-CCP) are present in most patients with rheumatoid arthritis (RA), and associate with HLA-DRB1 shared epitope (SE) alleles. OBJECTIVE: To investigate reactivities of anti-CCP to various citrullinated proteins/peptides, which represent potential autoantigens in RA, and to examine the relationship between such antibodies, and their association with genetic variants within HLA-DRB1 SE alleles. METHODS: Serum samples from 291 patients with established RA and 100 sex- and age-matched healthy subjects were included in this study. Sera were first analysed for presence of anti-CCP antibodies and further for IgG and IgA antibodies towards candidate autoantigens in both their native and citrullinated form including: fibrinogen, alpha-enolase peptide-1 and the C1-epitope of type II collagen (C1(III)). Antibody specificity was confirmed by cross-reactivity tests. HLA-DR genotyping was performed. RESULTS: 72% of patients with RA were anti-CCP positive. Among the candidate autoantigens examined, IgG antibodies to citrullinated fibrinogen were found in 66% of patients' sera and in 41% for both citrullinated alpha-enolase peptide-1 and citrullinated C1(III). These antibodies were mainly seen in the anti-CCP-positive patient group; they were specific for their respective antigen and displayed limited cross reactivity. IgA responses were also detected, but less frequently than IgG. Anti-CCP and anti-citrullinated protein antibodies were associated with HLA-DRB1*04 rather than with HLA-DRB1*01 alleles. CONCLUSIONS: Antibodies directed against several citrullinated antigens are present in CCP-positive RA, with many patients displaying multireactivity. All specific reactivities were primarily associated with the HLA-DRB1*04 alleles, suggesting common pathways of anti-citrulline immunity.

We report the case of inadvertent malpositioning of a pacemaker lead in the left ventricle. The lead went through an open foramen ovale from the right to the left atrium and through the mitral valve into the left ventricle. After a review of the literature, we decided to anticoagulate the patient and leave the electrode in place. During a follow-up period of 16 months, there were no clinical complications.

PURPOSE: Veno-arterial extracorporeal life support (ECLS) is increasingly used in patients during cardiac arrest and cardiogenic shock, to support both cardiac and pulmonary function. We performed a systematic review and meta-analysis of cohort studies comparing mortality in patients treated with and without ECLS support in the setting of refractory cardiac arrest and cardiogenic shock complicating acute myocardial infarction. METHODS: We systematically searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials and the publisher subset of PubMed updated to December 2015. Thirteen studies were included of which nine included cardiac arrest patients (n = 3098) and four included patients with cardiogenic shock after acute myocardial infarction (n = 235). Data were pooled by a Mantel-Haenzel random effects model and heterogeneity was examined by the I 2 statistic. RESULTS: In cardiac arrest, the use of ECLS was associated with an absolute increase of 30 days survival of 13 % compared with patients in which ECLS was not used [95 % CI 6-20 %; p < 0.001; number needed to treat (NNT) 7.7] and a higher rate of favourable neurological outcome at 30 days (absolute risk difference 14 %; 95 % CI 7-20 %; p < 0.0001; NNT 7.1). Propensity matched analysis, including 5 studies and 438 patients (219 in both groups), showed similar results. In cardiogenic shock, ECLS showed a 33 % higher 30-day survival compared with IABP (95 % CI, 14-52 %; p < 0.001; NNT 13) but no difference when compared with TandemHeart/Impella (-3 %; 95 % CI -21 to 14 %; p = 0.70; NNH 33). CONCLUSIONS: In cardiac arrest, the use of ECLS was associated with an increased survival rate as well as an increase in favourable neurological outcome. In the setting of cardiogenic shock there was an increased survival with ECLS compared with IABP.

Dendroaspis angusticeps (green mamba) has two toxins, fasciculins, that are non-competitive inhibitors of acetylcholinesterase. Amino groups of fasciculin 2 were acetylated with acetic anhydride. The monoacetyl derivatives of the epsilon-amino groups (Lys 25, 32, 51 and 58) retained between 28 and 43% of the initial activity and that of the alpha-amino group 72%. Acetylation of Lys 25 that has the most reactive amino group decreased the activity by 65% apparently without producing structural perturbations, since the circular dichroism spectrum was not affected. The three-dimensional structure shows a cationic cluster formed by Lys 32, 51, Arg 24 and 28. A comparison of 175 sequences of homologous toxins shows that Lys 32 is unique for fasciculin. Acetylation of lysine residues in the cluster had a large effect and reduced the activity by 72% (Lys 32) and 57% (Lys 51). This suggests an important role for the cationic cluster. Lys 25 together with Lys 32 and 51 were, therefore, assumed to be in the active site.

Pure colipase from dogfish (Squalus acanthius) was obtained from an extract of pancreatic gland. It has a high isoelectric point (10.2) and the molecular weight was calculated to be 9108-9383. The N-terminal sequence was shown to be Gly-Leu-Phe-Leu-Asn-Leu-Ser-Ala-Gly-Glu-Leu-Cys-Val-Gly-Ser-Phe-Gln -Cys-Lys-Ser-Ser-Cys-Cys-Gln-Arg-Glu-Thr-Gly-Leu-Ser-Leu-Ala -Arg-Cys-Ala-. This sequence shows great homology with colipases from man, horse, pig and hen. There were indications of the existence of a proform of dogfish colipase. The propeptide was found to be Ala-Pro-Glu-Arg.

The amino acid sequence of an activated colipase purified from human pancreas was determined. The protein consists of a single polypeptide chain of 86 amino acids (human colipase86) and has a molecular weight of 9289. The sequence was determined by automated Edman degradation of the reduced and S-carboxymethylated protein and of two CNBr peptides. Sequence determination of porcine procolipase II was also performed, which showed that in the original sequence determination apparently two residues were missed. These residues were determined to be a leucine at position 37 and a serine in position 50. For comparison with porcine and equine procolipases, the residues composing human colipase are numbered from 6 to 91. No human procolipase has been isolated so far. The colipases from man, pig, horse and chicken show a high degree of homology: human colipase differs from the other proteins by substitutions of 19 (porcine), 24 (equine A) and 21 (equine B) residues, respectively.

A peptide toxin affecting potassium channels was isolated from the sea anemone Bunodosoma granulifera. It facilitates acetylcholine release at avian neuromuscular junctions, competes with dendrotoxin I, a probe for voltage-dependent potassium channels, for binding to synaptosomal membranes of rat brain with a Ki of 0.7 nM and suppresses K+ currents in rat dorsal root ganglion neurones in culture. It represents a new structural type of potassium channel toxin with the sequence V1RCDWFKETA10CRHAKSLGNC20RTSQKYRANC30AKTLQCC37 (M(r) 4275, three disulfides).

The light chain expression in two IgE-producing rat immunocytomas, IR2 and IR162, was studied. Both immunocytomas produce light chains of the kappa type. The kappa chains were characterized at the protein level by sodium dodecylsulfate (SDS)-polyacrylamide gel electrophoresis (PAGE) and amino acid (aa) sequencing. cDNA clones corresponding to the kappa-chain mRNA were also prepared and sequenced. The results showed that rat kappa chains have the same structure as their mouse counterparts with respect to signal sequence cleavage, somatic mutations in the V-J region and invariance of all the aa positions which are strongly conserved in the frame work regions of mouse V kappa chains (greater than 95% conservation). Results from studies on kappa-chain transcription lend support to the allelic exclusion model with only one functionally expressed light chain in each immunocytoma.

Human tryptic C4d of the Chido and Rodgers variant was fragmented by cyanogen bromide and trypsin. The fragments were characterized by amino acid analysis and sequence determination. Polymorphism between the two genetic variants was detected in 5 positions. Four were closely located (residues 141, 142, 145, 146), where Leu, Ser, Ile, His occurred in the Chido variant and Pro, Cys, Leu, Asp in the Rodgers variant, respectively. In position 94 Gly was found in Chido and Asp in Rodgers. Alignment of the fragments was performed and it is concluded that tryptic C4d of both variants contains 346 residues.

Since 1980 General Mills Inc has regularly conducted studies of the mean daily intake of 25 nutrients from nationally representative samples of 4000 American households (approximately 10,000 individuals). This paper examines trends in sodium consumption derived from these studies. Calculated estimates of both discretionary and nondiscretionary intake indicate that overall sodium consumption has declined since the early 1980s. Shifts in food sources of sodium have occurred over the 10-y study period, with the greatest amounts of sodium coming from meats and mixed dishes. Greater interest in the sodium content of the diet is predicted because of the daily value listing on the new food label and the National Heart, Lung and Blood Institute's campaign to reduce sodium intake. Until an acceptable alternative for the salty taste from sodium chloride is available, offering reduced-sodium alternatives and gradually reducing the sodium content of existing products appears to be the food industry's best approach to meet consumers' concerns about sodium.

Diapausing pupae of Cecropia respond to a bacterial infection by the selective synthesis of RNA and 15-20 hemolymph proteins. Of these we have purified lysozyme and two classes of antibacterial proteins called cecropins and attacins. The primary structure has been determined for the lysozyme, one attacin and five cecropins. We have also prepared a cDNA bank, isolated and sequenced clones corresponding to the lysozyme, the two main attacins and one cecropin. The results of these structural studies are briefly summarized. Finally we review the solid phase synthesis of cecropin A and B and 9 analogs of cecropin A.
