Konst för städer i förändring - en förstudie
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Offentlig konst utgör en viktig del av stadsrummet och används i många olika syften. Det kan handla om att försköna platser och om att stärka känslan av tillhörighet och den lokala identiteten. Det finns också förväntningar på att konsten ska bidra till lösningar på samhällsproblem kopplade till brobyggande, otrygghet och segregation och lönsamhet genom att öka stadens attraktivitet. I denna rapport understryker vi vikten av att reflektera kritiskt över förväntningar på och villkor för offentlig konst i svenska kommuner. Rapporten behandlar hur konstprocesser kan påverka invånare och konstnärer och problematiserar för vem och i vems intresse den offentliga konsten skapas.

- Recent studies show that rectal colonization with low-level ciprofloxacin-resistant Escherichia coli (ciprofloxacin minimal inhibitory concentration (MIC) above the epidemiological cutoff point, but below the clinical breakpoint for resistance), i.e., in the range amp;gt; 0.06-0.5 mg/L is an independent risk factor for febrile urinary tract infection after transrectal ultrasound-guided biopsy (TRUS-B) of the prostate, adding to the other risk posed by established ciprofloxacin resistance in E. coli (MIC amp;gt; 0.5 mg/L) as currently defined. We aimed to identify the quinolone that by disk diffusion best discriminates phenotypic wild-type isolates (ciprofloxacin MIC amp;lt;= 0.06 mg/L) of E. coli from isolates with acquired resistance, and to determine the resistance genotype of each isolate. The susceptibility of 108 E. coli isolates was evaluated by ciprofloxacin, levofloxacin, moxifloxacin, nalidixic acid, and pefloxacin disk diffusion and correlated to ciprofloxacin MIC (broth microdilution) using EUCAST methodology. Genotypic resistance was identified by PCR and DNA sequencing. The specificity was 100% for all quinolone disks. Sensitivity varied substantially, as follows: ciprofloxacin 59%, levofloxacin 46%, moxifloxacin 59%, nalidixic acid 97%, and pefloxacin 97%. We suggest that in situations where low-level quinolone resistance might be of importance, such as when screening for quinolone resistance in fecal samples pre-TRUS-B, a pefloxacin (S amp;gt;= 24 mm) or nalidixic acid (S amp;gt;= 19 mm) disk, or a combination of the two, should be used. In a setting where plasmid-mediated resistance is prevalent, pefloxacin might perform better than nalidixic acid.

- Chlamydia pneumoniae has during recent years been associated with cardiovascular disease and atherosclerosis. Chemokines, leukocyte adhesion proteins and metalloproteinases are significant for chemotaxis and attachment of leukocytes to vessel walls, and for stability of atherosclerotic plaques. To determine the ability of C. pneumoniae to elicit inflammation in a relevant target host cell, we infected human coronary artery endothelial cells (HCAEC) with a clinical isolate of C. pneumoniae. Extracellular release of five chemokines, two adhesion proteins and a metalloproteinase was measured at different time points after infection using a cytometric bead assay and ELISA. Secretion of IL-8, MCP-1, MIG, IP-10 and ICAM-1 was significantly increased 48 h after C. pneumoniae infection of HCAEC in comparison with uninfected controls. Release of RANTES occurred already 6 h after infection. C. pneumoniae did not elicit release of E-selectin or MMP-1. We conclude that C. pneumoniae induces expression of proinflammatory components in HCAEC, which would promote migration of leukocytes towards endothelial cells. This suggests that C. pneumoniae initiates and propagates vascular inflammation in ways that contribute to coronary artery disease.

- Leucocyte esterase (LE) in first-voided urine (FVU) and presence of leucocytes in urethral and cervical smears were evaluated to identify Mycoplasma genitalium infection in 416 men and 417 women attending Department of Genitourinary Medicine. M. genitalium was diagnosed in FVU specimens by realtime polymerase chain reaction. The prevalence of M. genitalium was 6.5% in women and 6.7% in men. In total, 88.5% (23/26) of M. genitalium-infected men were identified by a combination of urethral smear and the LE test. In women, the combination of urethral and/or cervical smears and/or a positive LE test identified 91.3% (21/23) of M. genitalium-infected patients. Organism load in FVU correlated significantly with presence of urethritis (> or =4 leucocytes per high-power field) in men. A combination of LE testing of urine and urethral and/or cervical smears can be used as screening tests to select patients for specific M. genitalium testing. By this strategy, about 10% of infected individuals will remain undetected.

- Atherosclerosis and coronary heart disease are causing high morbidity and mortality worldwide. Different risk factors have been demonstrated, but the exact mechanisms behind these diseases are still not fully understood. Recent studies have suggested Chlamydia pneumoniae to be involved in the pathogenesis, and increased apoptotic indexes in atherosclerotic plaques have been documented. In this study, we show that C. pneumoniae induces apoptosis and necrosis in populations of human coronary artery endothelial cells. Apoptosis was determined by TUNEL and flow cytometry after staining of cells with annexin V and propidium iodide, and defined as TUNEL-reactive or annexin V-positive, propidium iodide-negative cells. The apoptosis was induced within 2 h postinfection and increased with inoculation dose. The general caspase inhibitor z-VAD-fmk did not affect apoptotic frequencies. By immunochemistry and immunoblot, we demonstrated activation and subcellular translocation of the proapoptotic protein Bax, and translocation of apoptosis-inducing factor from the cytosol to the nucleus. These results indicate that C. pneumoniae-induced apoptosis in human coronary artery endothelial cells is caspase-independent and regulated by Bax and apoptosis-inducing factor.
