Uppföljning av kvalitetsförändringar i ängs- och betesmark via NILS år 2008
- 2008

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Detta uppdrag är ett led i arbetet med att få fram tillförlitliga data om tillstånd och förändringar i kvalitet och hävd hos ängs- och betesmarker i det svenska odlingslandskapet. Ett av de kvantitativa delmålen för det nationella miljökvalitetsmålet ”Ett rikt odlingslandskap” lyder: ”Senast år 2010 ska samtliga ängs- och betesmarker bevaras och skötas på ett sätt som bevarar deras värden. Arealen hävdad ängsmark ska utökas med minst 5 000 hektar, och arealen hävdad betesmark av de mest hotade typerna ska utökas med minst 13 000 hektar till år 2010” (Miljödepartementet 2001). Detta projekt fokuserar således på naturvärdena, men kan också fungera som ett komplement till miljöstödsstatistiken vad gäller arealer av olika ängs- och betesmarkstyper.Som ett underlag används resultat från Ängs- och betesmarksinventeringen (Ä&B; Jordbruksverket 2005a, b) som genomfördes av Jordbruksverket i samarbete med länsstyrelserna under perioden 2002-2004 och har resulterat i en databas med avgränsning och beskrivning för huvuddelen av Sveriges skyddsvärda slåtter- och betesmarker, den så kallade TUVA-databasen.

- We studied history, renal histopathology and microbiology of an epidemic of acute glomerulonephritis associated with throat infections and uncommon culture results in four neighbour families. A 40-year-old man (index patient) was referred to a university hospital for dialysis and kidney biopsy due to a suspected acute glomerulonephritis. An acute tonsillitis had preceded the condition. Penicillin treatment had been started four days before the discovery of renal failure. Throat swabs were positive for β-hemolytic streptococci, group C (GCS). GCS were also found in throat cultures from his wife and two of their children. The bacteria were typed as Streptococcus constellatus. A third child had S. constellatus expressing Lancefield antigen group G. A neighbour and two of his children fell ill the following week with renal involvement. Throat swabs from both these children were positive for S. constellatus. His third child had erythema multiforme and S. constellatus in the throat while a fourth child had β-hemolytic streptococci group A, Streptococcus pyogenes. Kidney biopsies on the index patient and his neighbour showed an acute diffuse prolipherative glomerulonephritis compatible with acute post-streptococcal nephritis and microbiological analysis of renal tissue revealed in both cases S. pyogenes and S. constellatus. The families had had much contact and had consumed unpasteurized milk from our index patient's farm. In four of seven persons in two additional neighbouring families S. constellatus was found in throat swabs during the same month while two persons carried Streptococcus anginosus expressing the Lancefield C antigen. In conclusion spread of S. constellatus coincided with the occurrence of four cases of acute glomerulonephritis. The two biopsied patients had both S. pyogenes and S. constellatus present in renal tissue. The epidemic either suggested that the outbreak of glomerulonephritis was due to S. pyogenes but coincided with the transmission and colonization of S. constellatus or that the S. constellatus strains were highly pathogenic or nephritogenic and that this organism can be transmitted in such cases.

- AIM: To evaluate the outcome among patients suffering from out-of-hospital cardiac arrest (OHCA) after the introduction of mechanical chest compression (MCC) compared with standard cardiopulmonary resuscitation (SCPR) in two emergency medical service (EMS) systems. METHODS: The inclusion criterion was witnessed OHCA. The exclusion criteria were age < 18 years, the following judged etiologies behind OHCA: trauma, pregnancy, hypothermia, intoxication, hanging and drowning or return of spontaneous circulation (ROSC) prior to the arrival of the advanced life support (ALS) unit. Two MCC devices were allocated during six-month periods between four ALS units for a period of two years (cluster randomisation). RESULTS: In all, 328 patients fulfilled the criteria for participation and 159 were allocated to the MCC tier (the device was used in 66% of cases) and 169 to the SCPR tier. In the MCC tier, 51% had ROSC (primary end-point) versus 51% in the SCPR tier. The corresponding values for hospital admission alive (secondary end-point) were 38% and 37% (NS). In the subset of patients in whom the device was used, the percentage who had ROSC was 49% versus 50% in a control group matched for age, initial rhythm, aetiology, bystander-/crew-witnessed status and delay to CPR. The percentage of patients discharged alive from hospital after OHCA was 8% versus 10% (NS) for all patients and 2% versus 4%, respectively (NS) for the patients in the subset (where the device was used and the matched control population). CONCLUSION: In this pilot study, the results did not support the hypothesis that the introduction of mechanical chest compression in OHCA improves outcome. However, there is room for further improvement in the use of the device. The hypothesis that this will improve outcome needs to be tested in further prospective trials

- Dendritic cells (DC) represent the link between innate and adaptive immunity. They are classified as antigen-presenting cells (APC) and can initiate and modulate the immune response. To investigate the interaction with DCs, live RF-81 bovine rotavirus strain (RFV) and rotavirus-like particles (rota-VLP), RF 2/6-GFP-VLP and rota RF 8*2/6/7-VLP, were added in vitro to murine bone marrow-derived DCs (bmDCs). Live RFV, RF 2/6-GFP-VLP and RF 8*2/6/7-VLP all bound to bmDC and were internalized but only live RFV stimulated phenotypic maturation of the bmDCs as shown by the upregulation of the co-stimulatory molecule CD86. Even though bmDCs internalized RF 2/6-GFP-VLP and RF 8*2/6/7-VLP as efficiently as live RFV, these rota-VLP were not able to activate the cells. Supernatants derived from bmDC cultures treated with live RFV, RF 2/6-GFP-VLP or RF 8*2/6/7-VLP were examined for TNF-α production. At 6, 18 and 24 h post-infection, TNF-α concentrations were significantly increased in cultures treated with live RFV and rota-VLP compared with untreated cultures. In conclusion, this study showed that live RF-81 bovine rotavirus strain was internalized and induced bmDCs activation, whereas both RF 2/6-GFP-VLP and RF 8*2/6/7-VLP were internalized by bmDCs without triggering their activation. © 2007 The Authors.

Anaerobic digestion of alfalfa silage with recirculation of process liquid

- Process liquid recirculation initially stimulated one-phase anaerobic digestion of alfalfa silage in two semi-continuously fed and stirred tank reactors. Thus, with increased pH, alkalinity and stability it was possible to increase the organic loading rate to 3 g VS L-1 d-1, as compared to 2.25 g VS L-1 d-1 in a control reactor without recirculation. However, the recirculation of liquid eventually caused an accumulation of organic and inorganic substances, leading to an inhibition of hydrolysis and methanogenesis. This inhibition of microbial activity was prevented in one of the processes by replacing 50% of the recirculated process liquid with water during the second half of the operation period. A multiple linear regression model of principal components using seven input variables explained the variance in output variables nearly as well as the original model using all 23 measured input variables. The results show that it is necessary to adjust the degree of liquid recirculation to reach an optimal process. © 2005 Elsevier Ltd. All rights reserved.

- Despite the fact that distal radial fracture is the commonest fracture, there is a little evidence-based knowledge about the value of its classification to guide management and predict prognosis. The available classification systems are either complicated or weakly applicable in clinical practice. Older's classification is the most reliable, but does not cover all radial fracture types. We evaluated the interobserver and intraobserver reliability of a new classification system which is a modification of Older's classification covering all radial fracture types. Two hundred and thirty-two consecutive adult patients with acute distal radial fractures were blindly evaluated according to the new classification by three orthopedic surgeons twice with 1-year interval. The interobserver reliability was measured using the Fleiss kappa coefficient, and the intraobserver reliability was measured using the Cohen's kappa coefficient. The new classification showed fair to substantial interobserver and intraobserver reliability, i.e., results comparable to the reliability of commonly used classification systems. The reliability was better for younger patients and when evaluation was carried out by hand-surgery-interested orthopedic surgeons. The new classification system is simple, covers all radial fracture types, and has an acceptable reliability. Further studies are needed to judge its ability to direct management and predict prognosis.
