- BACKGROUND: Patterns may explain part of the dietary variation between subjects. OBJECTIVE: To create a typology of carbohydrate intake among the elderly and to analyse whether it seems valuable or not. DESIGN: Factor and cluster-analyses of dietary interviews from two elderly cohorts of free-living elderly people in Göteborg, Sweden. SUBJECTS AND METHODS: Three hundred and thirty seven women and three hundred and twenty three men aged 70-79 was studied cross-sectionally and longitudinally. The altogether 917 dietary interviews were based on the dietary history method. Cluster analysis, based on factor scores, was used to create the typology. RESULTS: Seven clusters were identified: 1) Small eaters (high relative intake of starch and a low energy intake), 2) Lean and green eaters (high intake of dietary fibre), 3) Fruit eaters (high intake of monosaccharides), 4) Sweet tooth eaters (high intake of sucrose), 5) Gourmands (high absolute intake of starch, dietary fibre and energy), 6) Milk drinkers (high intake of lactose) and 7) Fat eaters (high intake of fat and low intake of carbohydrates). The different patterns were associated with different food consumption, different intake of micronutrients and different social and physiological factors. There were also changes over time of the proportion of subject within the clusters. CONCLUSIONS: The typology found by using cluster analysis, seems to be valid and was related to all analysed dimensions. Therefore, the methods may be valuable for describing and analysing the dietary intake among elderly.

- Background Spironolactone, a cheap effective diuretic used to manage hypertension and heart failure, also has anti-androgenic effects through its non-selective binding to steroid receptors, and hence may affect prostate cancer (PCa) risk. This study investigated the association between spironolactone use and PCa risk. For comparison, we also examined associations with thiazide diuretics which do not have anti-androgenic properties. Methods A matched case-control study was undertaken using population-wide data from the Prostate Cancer Data Base Sweden (PCBaSe). All PCa cases diagnosed from 2014 to 2016 were matched by birth year and county with PCa-free controls selected from the general population (1:5). Multivariable conditional logistic regression was used to examine associations between spironolactone use (dose and duration) and PCa risk, and similarly for thiazides. Results Three percent of the 31,591 cases and 4% of the 156,802 controls had been prescribed spironolactone. Multivariable analyses indicated reduced risk of PCa among those ever exposed to spironolactone (odds ratio [OR] 0.83; 95% confidence interval [CI]: 0.76-0.89), with a stronger association for current users (OR: 0.77, 95% CI: 0.69-0.86) than past users (OR: 0.88; 95% CI: 0.79-0.97) and decreasing risk with increasing dose (p-trend < 0.001). No association was observed for thiazide exposure and PCa risk. Biases due to differences in prescribing patterns or frequency of PSA testing may have influenced these findings. Conclusion PCa risk was reduced among men exposed to the diuretic spironolactone. Further investigation of spironolactone's potential chemopreventive effects is warranted.

Structures of Solvated Cations of Palladium(II) and Platinum(II) in Dimethyl Sulfoxide, Acetonitrile and Aqueous Solution Studied by EXAFS and LAXS

- X-Ray absorption edge and EXAFS spectra of the solvated cations of platinum(II) in water, dimethyl sulfoxide and acetonitrile and of palladium(II) in dimethyl sulfoxide have been recorded and analyzed. The cations are four-coordinated. Pt-O in Pt(H2O)4(2+) is 2.01(1) angstrom and Pt-N in Pt(CH3CN)4(2+) is 2.00(1) angstrom. The dimethyl sulfoxide solvated cations of both platinum and palladium contain two sulfur- and two oxygen-bonded ligands with Pt-O 2.07(2), Pt-S 2.21(2), Pd-O 2.04(2), and Pd-S 2.23(2) angstrom, probably in a square-planar cis-arrangement, as in the solid state. Large-angle X-ray scattering (LAXS) studies of the platinum(II) dimethyl sulfoxide solvated cation in a solution of the triflate salt gave Pt-O 2.07(1) and Pt-S 2.20(1) angstrom and in a solution of the tetrafluoroborate salt Pt-O 2.07(2) and Pt-S 2.21(5) angstrom, in good agreement with the EXAFS results. Neither technique gave any support for axially bound solvent molecules in addition to the four in the assumed square coordination plane.

- Outcome after cardiac arrest is strongly related to whether the patient has ventricular fibrillation at the time the emergency medical service (EMS) arrives on the scene. The occurrence of various arrhythmias at the time of EMS arrival among patients with out-of-hospital cardiac arrest was studied in relation to the interval from collapse and whether cardiopulmonary resuscitation (CPR) was initiated by a bystander. The patients studied were all those with out-of-hospital cardiac arrest in Goteborg, Sweden, between 1980 and 1992 in whom CPR was attempted by the arriving EMS and for whom the interval between collapse and the arrival of EMS was known. In all, information on the time of collapse and the arrival of EMS was available for 1,737 patients. Among patients for whom EMS arrived within 4 minutes of collapse, 53% were found in ventricular fibrillation/tachycardia. There was a successive decline in occurrence of such arrhythmias with time. However, when the interval exceeded 20 minutes, ventricular fibrillation/tachycardia was still observed in 27% of cases. Bystander CPR increased the occurrence of such arrhythmias regardless of the interval between collapse and EMS arrival.

Biofilm formation by Propionibacterium acnes is a characteristic of invasive isolates

- Propionibacterium acnes is a common and probably underestimated cause of delayed joint prosthesis infection. Bacterial biofilm formation is central in the pathogenesis of infections related to foreign material, and P. acnes has been shown to form biofilm both in vitro and in vivo. Here, biofilm formation by 93 P. acnes isolates, either from invasive infections (n = 45) or from the skin of healthy people (n = 48), was analysed. The majority of isolates from deep infections produced biofilm in a microtitre model of biofilm formation, whereas the skin isolates were poor biofilm producers (p <0.001 for a difference). This indicates a role for biofilm formation in P. acnes virulence. The type distribution, as determined by sequencing of recA, was similar among isolates isolated from skin and from deep infections, demonstrating that P. acnes isolates with different genetic backgrounds have pathogenic potential. The biofilm formed on plastic and on bone cement was analysed by scanning electron microscopy (EM) and by transmission EM. The biofilm was seen as a 10-mum-thick layer covering the bacteria and was composed of filamentous as well as more amorphous structures. Interestingly, the presence of human plasma in solution or at the plastic surface inhibits biofilm formation, which could explain why P. acnes primarily infect plasma-poor environments of, for example, joint prostheses and cerebrospinal shunts. This work underlines the importance of biofilm formation in P. acnes pathogenesis, and shows that biofilm formation should be considered in the diagnosis and treatment of invasive P. acnes infections.
