    Sammanfattning : CO2 evasion to the atmosphere from inland waters is a major component of the global carbon (C) cycle. Yet spatial patterns of CO2 evasion and the sources of C that fuel evasion remain poorly understood. LÄS MER

  3. 8. Cholecystectomy : studies on surgical methods, incidence and economy

    Författare :Axel Ros; Ulf Haglund; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : After almost a century without change in the surgical care of gallstone disease since the first cholecystectomy in 1882, a profound change in surgical treatment of gallstones has taken place over the last three decades with the introduction of endoscopic sphincterotomy for treatment of bile duct stones (EST), minilaparotomy cholecystectomy (MC), and laparoscopic cholecystectomy (LC). The epidemiology of gallstone surgery has changed since these minimally invasive procedures were introduced. LÄS MER

  4. 9. Preeclampsia and other circulatory diseases during pregnancy : etiological aspects and impact on female offspring

    Författare :Helena Salonen Ros; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :preeclampsia; gestational hypertension; pregnancy-induced hypertension; risk factors; heritability; twin study; venous thrombosis; pulmonary embolism; subarachnoid hemorrhage; intracerebral hemorrhage; intracerebral infarction; stroke; intrauterine exposure;

    Sammanfattning : The aims of this thesis were to investigate and compare environmental effects on the liability of developing preeclampsia and gestational hypertension; to estimate the relative importance of genetic and environmental effects on the liability of developing preeclampsia and gestational hypertension; to assess the effect of childbearing on the risk of circulatory diseases; and to explore the effect of preeclampsia on the female offspring anthropometry in early adulthood. We used the Swedish Birth Register to compare the effect of maternal diabetes, multiple birth, smoking, place of birth and obesity, on the liability of developing preeclampsia and gestational hypertension among 10,666 primiparous women.
