- In recent years the Swedish Police Force (SPF) have encountered greater demands on availability and 24/7 services when dealing with errands that are regarded as low priority compared to regular police work, e.g. collecting tips from the public. One attempt to meet these increasing demands was the development of a mobile communications platform that allowed the public to communicate easily with the SPF using their own mobile phones by sending SMS and MMS. The focus of this paper is on the early phases of development of this m-service, in particular, on the specific technical issues such as interoperability and standards used by the actors on the scene affecting the development of mobile information systems. The learning experiences are as follows: First, mobile communication platforms have a large potential for contributing to the field of emergency management information systems since they can be based on open and nationally accepted standards. Second, global and national standards for sending multimedia messages are not always truly standardized. Operators and mobile phone manufacturers make minor alterations and interpretations of the standard and thereby some of the benefits found in standards disappear. Third, when developing mobile information systems we suggest and recommend that the analysis phase should be enhanced compared to traditional system development, and it should address the interoperability between mobile phones on one hand and operators on the other hand.

- In this study, we present a novel method to isolate and enrich low concentrations of Campylobacter pathogens. This method, Acanthamoeba-Campylobacter coculture (ACC), is based on the intracellular survival and multiplication of Campylobacter species in the free-living protozoan Acanthamoeba polyphaga. Four of the Campylobacter species relevant to humans and livestock, Campylobacter jejuni, C. coli, C. lari, and C. hyointestinalis, were effectively enriched by the coculture method, with growth rates comparable to those observed in other Campylobacter enrichment media. Studying six strains of C. jejuni isolated from different sources, we found that all of the strains could be enriched from an inoculum of fewer than 10 bacteria. The sensitivity of the ACC method was not negatively affected by the use of Campylobacter-selective antibiotics in the culture medium, but these were effective in suppressing the growth of seven different bacterial species added at a concentration of 10(4) CFU/ml of each species as deliberate contamination. The ACC method has advantages over other enrichment methods as it is not dependent on a microaerobic milieu and does not require the use of blood or other oxygen-quenching agents. Our study found the ACC method to be a promising tool for the enrichment of Campylobacter species, particularly from water samples with low bacterial concentrations.

Colour development in copper ruby alkali silicate glasses : Part 1. The impact of tin (II) oxide, time and temperature

- The development of the red colour in copper ruby alkali silicate glasses has been studied by means of ultraviolet/visible spectroscopy, TEM and EXAFS. The results show that in both red and slightly overstruck, brownish glasses the colour is due to clusters of metallic copper. Before striking non-coloured glasses contain mainly cuprous ions, Cu+. Tin acts as a reducing agent but also has an accelerating effect on colour development.

Selenium : molybdenum-based coloration of alkali silicate glasses

- The interaction between selenium and molybdenum in reduced alkali silicate melts, resulting in red glasses has been studied. The oxidation state of Mo is Mo(VI) as evidenced by XANES and ESCA results. Selenium is present in a reduced state, as indicated by ultraviolet/visible spectroscopy and XANES. The colour is described by ultraviolet/visible spectra and CIE colour coordinates. The main absorption peaks are at 450 and 540 nm. Similar bands are reported for MoOSe32−. Several commonly used glass components must be avoided in the batch, as they prevent formation of the red colour.

- AIM: To investigate whether nurses could be a useful tool for improving the reporting rate of adverse drug reactions (ADRs). Furthermore, we wanted to study how physicians working at the study departments would respond to nurses as reporters of ADRs and if the reporting from the nurses affected the reporting rate from the physicians.METHOD: Three departments of internal medicine and one unit for orthopaedics were selected for the study. Nurses with special drug responsibilities were invited to participate. At the start of the study period, the nurses received an introduction with background, objective, method and other practical issues concerning the study. After this, an education programme about ADR reporting, definitions, and ADR classification according to mechanism and organ system was given. To study their knowledge about and attitude towards ADRs, a questionnaire was handed out to the nurses. A questionnaire was also handed out to all physicians at the participating departments in order to investigate their attitude towards nurses as reporters of ADRs.RESULTS: Fifty-four nurses participated in the study. During the study period, a total number of 23 reports with 39 ADRs were sent to the regional centres by the nurses. Seventeen (74%) of the reports were assessed as serious. Eight of the 39 ADRs were unlabelled and all reports were considered appropriate. The reporting rate from the physicians during the study period was similar to the previous year, indicating that the nurses contributed with additional reports. At the end of the study, the nurses thought that they had enough knowledge to report ADRs. Sixty-eight percent of the physicians did not object to nurses being included as reporters of suspected ADRs.CONCLUSION: Adverse drug reaction reporting by nurses could improve the overall safety of drugs.

- Objectives. The aim of the study was to assess long-term state and trait anxiety in cardiac surgical risk patients. Design. Thirty two patients with serum S100B > 0.3 µg/l 48 hours after cardiac surgery with cardiopulmonary bypass were matched according to age, gender, type, date and length of surgery with 35 operated patients without elevated S100B. They completed Spielberger's Anxiety Inventory (STAI). Results. Patients with elevated S100B reported more state anxiety and trait anxiety. S100B was an independent predictor of both state and trait anxiety when controlling for perioperative variables. Conclusions. Patients with elevated S100B reported more anxiety 3–6 years after cardiac surgery. A postoperative blood sample can identify risk patients and facilitate appropriate follow-up.
