- The aim of this study was to compare the frequency of human leukocyte antigen (HLA) genotypes in 1-18-year-old patients with type 1 diabetes newly diagnosed in 1986-1987 (n = 430), 1996-2000 (n = 342) and in 2003-2005 (n = 171). We tested the hypothesis that the HLA DQ genotype distribution changes over time. Swedish type 1 diabetes patients and controls were typed for HLA using polymerase chain reaction amplification and allele specific probes for DQ A1* and B1* alleles. The most common type 1 diabetes HLA DQA1*-B1*genotype 0501-0201/0301-0302 was 36% (153/430) in 1986-1987 and 37% (127/342) in 1996-2000, but decreased to 19% (33/171) in 2003-2005 (P \ 0.0001). The 0501-0201/0501-0201 genotype increased from 1% in 1986-1987 to 7% in 1996-2000 (P = 0.0047) and to 5% in 2003-2005 (P > 0.05). This study in 1-18-year-old Swedish type 1 diabetes patients supports the notion that there is a temporal change in HLA risk.

- OBJECTIVE: The incidence of prostate cancer in Sweden is increasing rapidly, as is treatment with curative intent. Radical prostatectomy (RP) is currently commonly performed, either within or outside large high-volume centres. The aim of this study was to assess the 30-day mortality rate after RP in Sweden. MATERIAL AND METHODS: In this nationwide population-based study, all men diagnosed with localized prostate cancer (< or =70 years, clinical stadium T1-2, prostate-specific antigen < 20 ng/ml) who underwent RP in Sweden between 1997 and 2002 were identified through the National Prostate Cancer Register (NPCR). Mortality within 30 days of RP was analysed through linkage between the follow-up study of the NPCR and the Regional Population Registers. The cause of death in the death certificates were compared with data from the hospitals concerned. To validate the results, a record linkage between the Inpatient Register and the National Population Register was also performed. RESULTS: The number of RPs performed increased over time. Among 3700 RPs performed, four deaths occurred during the first 30 days, yielding a 0.11% 30-day mortality rate. These deaths occurred at three different types of hospital and were all probably related to the RP. CONCLUSION: This study provides further evidence that RP is a procedure with very low perioperative mortality even when performed outside high-volume centres.

- The lipid content of bile may be modified by the gallbladder epithelium. Recent studies indicate that cholesterol can be absorbed from bile and that this can be enhanced by apolipoprotein (apo) A-I. SR-BI is a multifunctional receptor capable of binding a wide array of native or modified lipoproteins, phospholipid or bile acid micelles. As apo A-I is a ligand for scavenger receptor class B type I (SR-BI) we have characterized the expression of this receptor in murine gallbladder.Reverse transcription-polymerase chain reaction (RT-PCR), immunoblotting and immunohistochemistry were used to study SR-BI expression in murine gallbladders. SR-BI expression was also used to examine gallbladders from high-fat-fed wild-type and apo B-100 transgenic mice.SR-BI and SR-BII mRNA are expressed in gallbladder. SR-BI immunoreactivity was localized to the columnar epithelium of the gallbladder. Immunoreactive SR-BI in gallbladder had an estimated molecular weight of 57 kDa, in contrast to the expected 82 kDa. Deglycosylation experiments indicated that the size difference between the two forms of the receptor is due to post-translational modification. Fat feeding of apo B transgenic mice resulted in gallstone formation but had no effect on the abundance of SR-BI.Gallbladder epithelial cells express SR-BI. This opens the possibility that SR-BI may influence the modification of bile in the gallbladder.

- The World Health Organization and the International Council of Nurses recognises the importance of nurses' involvement in disaster preparedness and response. The aim of this study was to describe and compare self reported disaster nursing competence (DNC) among nursing students (NSs) and among registered nurses (RNs) with professional experience. Further to investigate possible associations between self-reported DNC and background factors. A cross-sectional study was conducted of 569 NSs and 227 RNs. All respondents completed the 88-item Nurse Professional Competence Scale, including three items assessing DNC. Significant differences were found among the NSs depending on which University/University College they had attended. RNs reported significantly higher overall DNC and better ability to handle situations involving violence, and to apply principles of disaster medicine during serious events. RNs working in emergency care reported significantly better DNC ability, compared with RNs working in other areas of healthcare. Multiple linear regression analysis showed that working night shift and working in emergency care were positively associated with high self-reported overall DNC. The results indicate that workplace experience of serious events increase the readiness of registered nurses to handle violence, to act in accordance with safety regulations, and to apply principles of disaster medicine during serious events.

- Due to globalization, there is a need for nurses with skills and competence in providing safe, competent and culturally appropriate care. The aim of the study was to investigate whether International Study Experiences (ISE) in other countries during basic nursing education had an impact on newly graduated nurses as regards to self-reported competence. Moreover, a second aim was to explore what background factors that facilitated or constituted a hindrance for nursing students to choose to conduct part of their basic nursing education abroad. At 11 Universities/University Colleges (henceforth called Higher Education Institutions [HEIs]) in Sweden, 565 nursing students responded to the Nurse Professional Competence (NPC) Scale. Students with ISE rated their competence significantly higher on three NPC competence areas; “Legislation in nursing and safety planning”, “Leadership and development of nursing” and “Education and supervision of staff/students”. Background factors that significantly seemed to enhance ISE were; living alone, not having children or other commitments, international focus at the HEI and previous international experience. Lack of financial means was reported to prevent students from choosing ISE. The study implies that several background factors are of importance whether students choose ISE or not. ISE during basic nursing education might result in better self-reported competence in leading and developing nursing care, including education of future nurses, and in providing safe care.

- Objective: To assess the cost-effectiveness of induction of labour (IOL) at 41weeks of gestation compared with expectant management until 42weeks of gestation. Design: A cost-effectiveness analysis alongside the Swedish Post-term Induction Study (SWEPIS), a multicentre, randomised controlled superiority trial. Setting: Fourteen Swedish hospitals during 2016–2018. Population: Women with an uncomplicated singleton pregnancy with a fetus in cephalic position were randomised at 41weeks of gestation to IOL or to expectant management and induction at 42weeks of gestation. Methods: Health benefits were measured in life years and quality-adjusted life years (QALYs) for mother and child. Total cost per birth was calculated, including healthcare costs from randomisation to discharge after delivery, for mother and child. Incremental cost-effectiveness ratios (ICERs) were calculated by dividing the difference in mean cost between the trial arms by the difference in life years and QALYs, respectively. Sampling uncertainty was evaluated using non-parametric bootstrapping. Main outcome measures: The cost per gained life year and per gained QALY. Results: The differences in life years and QALYs gained were driven by the difference in perinatal mortality alone. The absolute risk reduction in mortality was 0.004 (from 6/1373 to 0/1373). Based on Swedish life tables, this gives a mean gain in discounted life years and QALYs of 0.14 and 0.12 per birth, respectively. The mean cost per birth was €4108 in the IOL group (n=1373) and €4037 in the expectant management group (n=1373), with a mean difference of €71 (95%CI −€232 to €379). The ICER for IOL compared with expectant management was €545 per life year gained and €623 per QALY gained. Confidence intervals were relatively wide and included the possibility that IOL had both lower costs and better health outcomes. Conclusions: Induction of labour at 41weeks of gestation results in a better health outcome and no significant difference in costs. IOL is cost-effective compared with expectant management until 42weeks of gestation using standard threshold values for acceptable cost per life year/QALY. Tweetable abstract: Induction of labour at 41weeks of gestation is cost-effective compared with expectant management until 42weeks of gestation.

- L-Cysteine potentiates 100-fold the hydrogen peroxide-induced killing of a growing culture of Escherichia coli K-12 (Berglin et al., J. Bacteriol. 152:81-88). In the present study it is shown that hydrogen sulfide is formed from L-cysteine and that sodium sulfide could substitute for L-cysteine in the potentiation of hydrogen peroxide-induced killing of E. coli K-12. Addition of an amino acid, L-leucine, L-valine, or L-alanine, to an L-cysteine-containing medium with a growing culture of E. coli K-12 inhibited hydrogen sulfide formation and the potentiation of hydrogen peroxide-induced killing. These amino acids did not inhibit hydrogen sulfide formation from L-cysteine by a cell extract, and they did not inhibit the potentiation by sulfide of hydrogen peroxide-induced killing. This indicated that the amino acids protected the culture from L-cysteine-potentiated, hydrogen peroxide-induced killing by inhibiting the transport of L-cysteine into the cell. The potentiation by sodium sulfide of hydrogen peroxide-induced killing was abolished by the metal ion chelator 2,2'-bipyridyl. This indicated that metal ions, in addition to sulfide, were involved in the killing. Toxic effects of hydrogen peroxide are often presumed to be mediated by hydroxyl radicals formed in iron-catalyzed reactions. It was demonstrated that iron sulfide was more efficient than ferrous iron in catalyzing the formation of hydroxyl radicals from hydrogen peroxide. It was suggested that hydrogen sulfide formed in polymicrobial infections may play an important role in the host defense by potentiating the antimicrobial effect of hydrogen peroxide produced by phagocytic cells.

- Under anaerobic conditions an exponentially growing culture of Escherichia coli K-12 was exposed to hydrogen peroxide in the presence of various compounds. Hydrogen peroxide (0.1 mM) together with 0.1 mM L-cysteine or L-cystine killed the organisms more rapidly than 10 mM hydrogen peroxide alone. The exposure of E. coli to hydrogen peroxide in the presence of L-cysteine inhibited some of the catalase. This inhibition, however, could not fully explain the 100-fold increase in hydrogen peroxide sensitivity of the organism in the presence of L-cysteine. Of other compounds tested only some thiols potentiated the bactericidal effect of hydrogen peroxide. These thiols were effective, however, only at concentrations significantly higher than 0.1 mM. The effect of L-cysteine and L-cystine could be annihilated by the metal ion chelating agent 2,2'-bipyridyl. DNA breakage in E. coli K-12 was demonstrated under conditions where the organisms were killed by hydrogen peroxide.
