Journal article (peer-reviewed)abstract
- International migrants often have lower mortality rates than the native populations in their new host countries. Several explanations have been proposed, but in the absence of data covering the entire life courses of migrants both before and after each migration event, it is difficult to assess the validity of different explanations. In the present study, we apply hazard regressions to Swedish register data to study the mortality of long-distance migrants from Northern to Southern Sweden as well as the mortality of return migrants to the North. In this way, we can study a situation that at least partly resembles that of international migration while still having access to data covering the full demographic biographies of all migrants. This allows us to test the relative roles of salmon bias and healthy migrant status in observed mortality rates of long-distance migrants. We find no mortality differentials between residents in northern and southern Sweden, and no evidence of a selection of healthy migrants from the North to the South. In contrast, we provide clear evidence of salmon effects' in terms of elevated mortality of the return migrants to northern Sweden, which are produced when migrants return to their place of origin in relation to subsequent death.

Fiskbestånd och miljö i hav och sötvatten : Resurs- och miljööversikt 2012
- 2012
-
Reports (other academic/artistic)abstract
- Detta är den nionde utgåvan av den samlade översikten över fisk- och kräftdjursbeståndens status i våra vatten. Kunskap om fiskbestånden och miljön är en förutsättning för att utnyttjandet av fiskresurserna skall bli bärkraftigt. För svenska vattenområden beskrivs miljöutvecklingen i ett ekosystemsperspektiv, dels för att tydliggöra fiskens ekologiska roll och beskriva yttre miljöfaktorer som påverkar fiskbestånden, dels för att belysa fiskets effekter på miljön.Fiskbestånd och miljö i hav och sötvatten är utarbetad av Sveriges lantbruksuniversitet (SLU), Institutionen för akvatiska resurser (SLU Aqua), på uppdrag av Havs- och vattenmyndigheten. Rapporten sammanfattar utveckling och beståndsstatus för de kommersiellt viktigaste fisk- och kräftdjursarterna i våra vatten. Bedömningar och förvaltningsråd är baserade på Internationella Havsforskningsrådets (ICES) rådgivning, SLU Aquas nationella och regionala provfiskedata, samt yrkesfiskets rapportering.

Low symptomatic load in Crohn's disease with surgery and medicine as complementary treatments
- 1998

In: Scandinavian Journal of Gastroenterology. - : Informa Healthcare. - 0036-5521 .- 1502-7708. ; 33:4, s. 423-429

Journal article (peer-reviewed)abstract
- Background: The treatment of Crohn's disease has changed owing to the recognition of its chronicity. Medical maintenance treatment and limited resections have evolved as major concepts of management, regarded as complementary, and both aim at reducing the symptoms.Methods: We investigated the symptomatic load in Crohn's disease as reflected in a cross-sectional study of the symptom index, physicians' assessment, and the patients' perception of health. A cohort of 212 patients from the primary catchment area and 125 referred patients were studied.Results: Of catchment area patients, 83% were receiving medication, and the annual rate of abdominal surgery was 5.7%. Corresponding figures for the referred patients were 82% and 10.3%. According to the symptom index, 87% of catchment area patients were in remission or had only mild symptoms; according to the physicians' assessment, 90% were. The patients' median perception of health was 90% of perfect health according to the visual analogue scale. The figures were similar for referred patients, except that referrals were considered more diseased by the physician.Conclusion: The great majority of patients with Crohn's disease are able to live in remission or experience only mild symptoms.
