Abstract
BACKGROUND An eHealth intervention using computer tailored technology including several behavior change techniques was developed to support the self-management of chronic obstructive pulmonary disease patients. OBJECTIVE The goal of this study was to evaluate and improve the usability of the eHealth intervention. METHODS We conducted a usability evaluation with 8 chronic obstructive pulmonary disease patients, with a mixed methods design. We improved the usability through iterative cycles of evaluation and adaptation. Participants were asked to think aloud during the evaluation sessions. Participants then completed a semi-structured interview. The sessions were observed and recorded. Descriptive statistics and content analysis were used to uncover usability issues. RESULTS Areas for improvement were layout, navigation, and content. Most issues could be solved within 3 iterations of improvement. Overall, participants found the program easy to use. The length of the program urged us to further analyze the appreciation of behavior change techniques. Some were perceived as helpful and easy to use, while others evoked frustration. CONCLUSIONS The usability study identified several issues for improvement, confirming the need for usability evaluation during the development of eHealth interventions. The uncovered strengths and limitations of behavior change techniques may lead to optimization of eHealth interventions, but further insight is needed.

Abstract
The dairy industry suffers massive economic losses due to staphylococcal mastitis in cattle. The Staphaureux latex agglutination test (Oxoid, Basel, Switzerland) was reported to lead to negative results in 54% of bovine Staphylococcus aureus strains, and latex-negative strains are thought to be less virulent than Staphaurex latex-positive strains. However, comparative information on virulence and resistance profiles of these 2 groups of Staph. aureus is scarce. Our objective was to associate the latex agglutination phenotype of Staph. aureus strains isolated from bovine mastitis milk with data on clonal complexes, virulence genes, and antibiotic resistance to (1) determine the virulence profiles of the Staphaureux test positive and Staphaurex test negative groups, and (2) provide data needed to improve treatment of bovine mastitis and to identify potential vaccine targets. Seventy-eight Staph. aureus strains isolated from 78 cows on 57 Swiss farms were characterized. Latex agglutination was tested by Staphaureux kit, and resistance profiles were generated by disk diffusion. A DNA microarray was used to assign clonal complexes (CC) and to determine virulence and resistance gene profiles. By the Staphaureux test, 49% of the isolates were latex-positive and 51% were latex-negative. All latex-negative strains were assigned to CC151, whereas latex-positive strains were assigned to various clonal complexes, including CC97 (n=16), CC8 (n=10), CC479 (n=5), CC20 (n=4), CC7 (n=1), CC9 (n=1), and CC45 (n=1). Although the latex-negative isolates were susceptible to all antimicrobial agents tested, 24% of latex-positive isolates were classified as intermediate with regard to cefalexin-kanamycin and 13% were resistant to both ampicillin and penicillin. Microarray profiles of latex-negative isolates were highly similar, but differed largely from those of latex-positive isolates. Although the latex-negative group lacked several enterotoxin genes and sak, it exhibited significantly higher prevalence rates of genes encoding enterotoxin C, toxic shock syndrome toxin, and leukocidins (lukM/lukF-P83, lukD). Our findings suggest that latex-negative isolates represent a group of closely related strains with specific resistance and virulence gene patterns.

Abstract
A new scale-up concept based upon mixing models for bioreactors equipped with Rushton turbines using the tanks-in-series concept is presented. The physical mixing model includes four adjustable parameters, i.e., radial and axial circulation time, number of ideally mixed elements in one cascade, and the volume of the ideally mixed turbine region. The values of the model parameters were adjusted with the application of a modified Monte-Carlo optimization method, which fitted the simulated response function to the experimental curve. The number of cascade elements turned out to be constant (N = 4). The model parameter radial circulation time is in good agreement with the one obtained by the pumping capacity. In case of remaining parameters a first or second order formal equation was developed, including four operational parameters (stirring and aeration intensity, scale, viscosity). This concept can be extended to several other types of bioreactors as well, and it seems to be a suitable tool to compare the bioprocess performance of different types of bioreactors.

Abstract
This paper describes a new genus and a new species of Euptychiina from open grassland habitats (campos de cima da serra) in southern Brazil. The systematic position of this new taxon is discussed based on morphological and molecular data, and it is considered sister to Taydebis Freitas. Since the campos vegetation is considered endangered due to anthropogenic activities, this butterfly species deserves attention and should be included in future conservation plans for this biome.

Abstract
BACKGROUND The need for research methods that are suited to evaluate important issues and phenomena in palliative care has established different qualitative research approaches during the last years. This article describes the use and adaptation of a qualitative research methodology in a palliative care setting. RESEARCH PROCESS The wish for hastened death of terminally ill patients is an important end-of-life issue. Proponents of palliative care have argued that good palliative care would prevent the wish for hastened death. However, this wish is stated by a few patients receiving palliative care, raising a challenging dilemma for patients, relatives and caregivers involved. In order to investigate the motivations of the patients asking for hastened death, we conducted a qualitative study using Grounded theory (GT). This article aims to illustrate the use of a flexible, less burdening qualitative research method and the adaptation of the research process of GT in a palliative care research setting. This is based on experiences and illustrated by examples from the qualitative study on the wish for hastened death in patients receiving palliative care. CONCLUSIONS GT allowed a systematic understanding of patients' experiences and attitudes and careful in-depth exploration of this vulnerable population. Conducting a GT study needs high staff resources, a great catchment area for participant recruitment and realistic inclusion and exclusion criteria to allow for theoretical sampling. The use of GT should be facilitated by an experienced researcher familiar with this method because of high methodological requirements and rather complex analysis procedures.

Abstract
RATIONALE, AIMS AND OBJECTIVES The admission to a hospital for elective surgery, like arthroplasty, can be planned ahead. The elective nature of arthroplasty and the increasing stimulus of the public to critically select a hospital raise the issue of how patients actually take such decisions. The aim of this paper is to describe the decision-making process of selecting a hospital as experienced by people who underwent elective joint arthroplasty and to understand what factors influenced the decision-making process. METHODS Qualitative descriptive study with 18 participants who had a hip or knee replacement within the last 5 years. Data were gathered from eight individual interviews and four focus group interviews and analysed by content analysis. RESULTS Three categories that influenced the selection of a hospital were revealed: information sources, criteria in decision making and decision-making styles within the GP- patient relationship. Various contextual aspects influenced the decision-making process. Most participants gave higher priority to the selection of a medical specialist than to the selection of a hospital. CONCLUSION Selecting a hospital for arthroplasty is extremely complex. The decision-making process is a highly individualized process because patients have to consider and assimilate a diversity of aspects, which are relevant to their specific situation. Our findings support the model of shared decision making, which indicates that general practitioners should be attuned to the distinct needs of each patient at various moments during the decision making, taking into account personal, medical and contextual factors.

Abstract
OBJECTIVES Our laboratory of microbiology use the VersaTREK/ESP Culture System II for the isolation of mycobacteria. In this study, we evaluate this system for the analysis carried out between April 2009 and March 2010. METHOD The Myco bottles are supplemented with growth supplements and an antimicrobial agent solution prior to inoculation with the specimen. The technology of the VersaTREK/ESP Culture System II is based on the detection of headspace pressure changes within a sealed bottle. It monitors changes in either gas production or gas consumption due to microbial growth. A special algorithm has been developed for detection of very slow growing mycobacteria. The bottles are incubated during 42 days. Meanwhile a solid medium is inoculated too. All specimen types can be analysed with this system. RESULTS Compared to solid culture, the time needed for detection of positive cultures was significantly shorter for the VersaTREK with a good recovery rate. For isolates recovered in both systems, mean time of detection is respectively 19.1 and 35.6 days for liquid and solid cultures. Mycobacteria identification may be determined using nucleic acid probs directly in Myco VersaTREK or in the solid medium. The susceptibility test of Mycobacteria tuberculosis complex is obtained between six and 13 days for rifampin, isoniazid, ethambutol, streptomycin and pyrasinamide. CONCLUSION This system offers a faster diagnosis and is an alternative to other instruments using liquid culture.

Abstract
The goal of this article is to augment the ethical discussion among nurses with the findings from empirical research on autonomy of older adults with type 2 diabetes mellitus. There are many factors influencing autonomy. These include: health conditions, treatment, knowledge, experience and skills, personal approach as well as familial patterns, type of relationship, life history and social context. Fifteen older adults with type 2 diabetes mellitus were interviewed in a nurse-led diabetes clinic. These participants perceive three processes which support autonomy in responsive relationships: preserving patterns of concern and interaction, nurturing collaborative responsibilities and being closely engaged in trustful and helpful family relations. People with diabetes realize autonomy in various responsive relationships in their unique life context. Next, we performed a literature review of care ethics and caring in nursing with regard to relational autonomy. We classified the literature in five strands of care: attitude-oriented, dialogue-oriented, activity-oriented, relationship-oriented and life-oriented. According to our respondents, autonomy in responsive relationships is fostered when patient, nurses, professionals of the health team and family members carry out care activities supported by a relational attitude of care. They can best realize autonomy in relationships with others when several essential aspects of care and caring are present in their lives. Therefore, we advocate a comprehensive approach to care and caring.

Abstract
Rhizomelic chondrodysplasia punctata is a rare autosomal recessive disorder characterized by stippled epiphyses and rhizomelic shortening of the long bones. We report 3 subjects of rhizomelic chondrodysplasia punctata from India and the PEX7 mutations identified in them. The common PEX7-L292X allele, whose high frequency is due to a founder effect in the northern European Caucasian population, was not identified in these patients. Instead, 2 novel alleles are described, including 64_65delGC, which was present on a single PEX7 haplotype and could represent a common allele in the Indian population.

Abstract
OBJECTIVE To get insights into the decision-making strategy of health-care consumers when confronted with comparative consumer information. METHODS Qualitative descriptive study among 18 consumers who had a hip or knee replacement no longer than five years ago. To study their decision-making strategies a paper draft for a website was used providing comparative consumer information. Data were collected by cognitive interviews and focus-group meetings and subjected to thematic analysis. RESULTS Consumers were able to understand the presented information, but had problems to use it as a decision aid. They primarily relied on previous experiences. Four themes were revealed: decision making, perceived benefits, unmet information needs, and trustworthiness. Consumers used different decision strategies and showed unpredictable behavior when choosing a hospital. CONCLUSION Individual decision strategies, unsatisfied information needs, limited tenability and too coarse aggregation levels of quality scores are barriers for a proper use of comparative consumer information. Personal experience remains a valuable information source for hospital selection. We suggest that a website presenting comparative consumer information should be flexible in various ways and should include functionality to share personal experience.
