Standardiserat elfiske i vattendrag

Denna rapport utgor bade en vagledning for standardiserat elfiske i vattendrag och en allman oversikt om elfiske som provfiskemetod. Vagledningen ar utformad enligt de riktlinjer for standardiserat elfiske som Sotvattenslaboratoriet, institutionen for akvatiska resurser vid Sveriges lantbruksuniversitet, har tagit fram for elfiske inom nationella miljoovervakningsprogram. Syftet ar att rapporten skall kunna anvandas bade som en manual med praktiska rad och som ett allmant uppslagsverk for elfiske. Den skall utgora ett grunddokument for elfiskeverksamheten i Sverige och aven for utbildning i elfiske. I rapporten presenteras information om det mesta som ror elfiske som provfiskemetod; till exempel bestammelser som ror tillstand for elfiske och djuretiska aspekter vid praktiskt elfiske, men ocksa information om olika typer av elektrisk strom och grundlaggande stromlara. I rapporten beskrivs fiskens reaktion pa elektrisk strom, faktorer som paverkar fangsteffektivitet och risken for skador pa fisken. Vidare behandlas olika typer av elfiskeutrustning, planering och praktiskt utforande av elfiske, standardiserat elfiske, faltrapportering, bearbetning och utvardering av elfiskedata. Dessutom ges information om olycksrisker, elsakerhet och skyddsinstruktion for elfiske

Pre- and post-vaccination characteristics and risk factors for COVID-19 outcomes in a Swedish population-based cohort of COPD patients

Rationale Evidence on risk factors for Coronavirus disease 2019 (COVID-19) outcomes among patients with COPD in relation to COVID-19 vaccination remains limited. The objectives of the present study were to characterise determinants of COVID-19 infection, hospitalisation, intensive care unit (ICU) admission and death in COPD patients in their unvaccinated state compared to when vaccinated. Methods We included all COPD patients in the Swedish National Airway Register (SNAR). Events of COVID-19 infection (test and/or healthcare encounter), hospitalisation, ICU admission and death were identified from 1 January 2020 to 30 November 2021. Using adjusted Cox regression, associations between baseline sociodemographics, comorbidities, treatments, clinical measurements and COVID-19 outcomes, during unvaccinated and vaccinated follow-up time, were analysed. Results The population-based COPD cohort included 87 472 patients, among whom 6771 (7.7%) COVID-19 infections, 2897 (3.3%) hospitalisations, 233 (0.3%) ICU admissions and 882 (1.0%) COVID-19 deaths occurred. During unvaccinated follow-up, risk of COVID-19 hospitalisation and death increased with age, male sex, lower education, non-married status and being foreign-born. Comorbidities increased risk of several outcomes, e.g. respiratory failure for infection and hospitalisation (adjusted hazard ratios (HR) 1.78, 95% CI 1.58–2.02 and 2.51, 2.16–2.91, respectively), obesity for ICU admission (3.52, 2.29–5.40) and cardiovascular disease for mortality (2.80, 2.16–3.64). Inhaled COPD therapy was associated with infection, hospitalisation and death. COPD severity was also associated with COVID-19, especially hospitalisation and death. Although the risk factor panorama was similar, COVID-19 vaccination attenuated HRs for some risk factors. Conclusion This study provides population-based evidence on predictive risk factors for COVID-19 outcomes and highlights the positive implications of COVID-19 vaccination for COPD patients
