    Abstract : Essay I: This paper studies the effect of air pollution on infant health in Sweden. Combining register panel data on birth outcomes and family characteristics with pollution data, I estimate the effect of particulate matter (PM10) on several birth outcomes that previously have been shown to be predictive of future outcomes.

  4. 2. Essays on the effect of health care and the environment on health

    Author : Linn Mattisson; Nationalekonomiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Primary care; Digital care; Telemedicine; Physician visits; practice closures; Continuity of care; health care spillovers; waterborne diseases; Sanitation; Test scores; Child Health; Children s learning;

    Abstract : This thesis consists of three self-contained papers studying different topics in health economics. The first chapter studies the substitution effect between in-person physician visits and a new type of doctor visits, direct-to-consumer (DCT) telemedicine, where a person can call a doctor directly via an app. READ MORE

  5. 3. Genetic variation of HIV-1 : molecular epidemiology and viral evolution

    Author : Thomas Leitner; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : HIV-1 displays a very high genetic variability. The evolutionary process of the virus generates a nucleotide substitution rate which is approximately one million times faster than that of higher organisms. This remarkable rate in combination with a half-life of six to eight hours, gives HIV-1 an enormous potential of genetic adaptation. READ MORE

  6. 4. Genetic aspects of HIV-1 evolution and transmission

    Author : Irina Maljkovic Berry; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : HIV-1 is one of the fastest evolving organisms known to man. Its rate of evolution is approximately one million times faster than that of higher organisms such as ourselves, meaning that the amount of changes within the HIV-1 genome in just one year corresponds to the amount of changes within the human genome in one million years.

  7. 5. Structural and genetic characterization of lipopolysaccharides extracted from disease causing non-typeable Haemophilus influenzae strains

    Author : Mikael Engskog; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : This thesis deals with the structure and genetic blueprint of lipopolysaccharides (LPS) expressed by the Gram-negative bacterium Haemophilus influenzae (H.influenzae). H. influenzae is an opportunistic pathogen that regularly colonizes the upper respiratory tract and exists in encapsulated (typeable) or nonencapsulated (non-typeable) forms (NTHi). READ MORE
