1. 21. Visual dysfunction and ocular signs associated with periventricular leukomalacia in children born preterm

   Författare :Lena Jacobson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :preterm; retinopathy of prematurity; periventricular leukornalacia; magnetic resonance imaging; delayed visual maturation; visual acuity; crowding; visual field; cognitive visual dysfunction; optic disc; cupping; eye movements; nystagmus; strabismus; reading;

   Sammanfattning : The immature visual system is vulnerable to adverse events in infants born preterm. Both retinopathy of prematurity and periventricular leukomalacia may affect visual function and ocular appearance. LÄS MER

3. 22. Visual motor development in full term and preterm infants

   Författare :Helena Grönqvist; Claes von Hofsten; Kerstin Rosander; Audrey van der Meer; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; infant development; smooth pursuit; eye tracking; reaching; preterm infants; Psychology; Psykologi; Psychology; Psykologi;

   Sammanfattning : Smooth tracking and efficient reaching for moving objects require the ability to predict the velocity and trajectory of the object. This skill is important to be able to perceive human action and object motion in the world. This thesis explores early visual motor development in full term and preterm infants. LÄS MER

4. 23. Discrepancy between pregnancy dating methods – correlates and outcomes

   Författare :Merit Kullinger; Alkistis Skalkidou; Helle Kieler; Karin Källén; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pregnancy; gestational age; ultrasound; last menstrual period; Obstetrik och gynekologi; Obstetrics and Gynaecology;

   Sammanfattning : With the introduction of obstetric ultrasound there has been a shift from last menstrual period-based to ultrasound-based estimation of gestational age. The choice of the method and timing of pregnancy dating is important because it can affect dating precision and perinatal outcomes. LÄS MER

5. 24. Genetic and epidemiological aspects of implantation defects : Studies on recurrent miscarriage, preeclampsia and oocyte donation

   Författare :Evangelia Elenis; Agneta Skoog Svanberg; Alkistis Skalkidou; Gunilla Sydsjö; Helena Åkerud; Anja Pinborg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiogenesis; genetic polymorphism; gestational hypertensive disorders; Histidine-rich glycoprotein; HRG; implantation defect; oocyte donation; placentation; preeclampsia; recurrent miscarriage; SNP.; Obstetrik och gynekologi; Obstetrics and Gynaecology;

   Sammanfattning : Implantation requires complex molecular and cellular events involving coagulation, angiogenesis and immunological processes that need to be well regulated for a pregnancy to establish and progress normally.  The overall aim of this thesis was to study different models associated with atypical angiogenesis, impaired implantation and/or placentation, such as recurrent miscarriage (RM), oocyte donation (OD) and preeclampsia.

7. 25. Prevention of Mother to Child Transmission of HIV in Africa : Operational Research to Reduce Post-natal Transmission and Infant Mortality

   Författare :Mickey Chopra; Lars-Åke Persson; Ted Greiner; Cesar Victora; Uppsala universitet; []
   Nyckelord :HIV AIDS; Prevention of Mother to Child Transmission of HIV; infant feeding; child health; cohort study; health systems evaluation; effectiveness;

   Sammanfattning : This thesis assesses the effectiveness of the National Prevention of Mother to Child Transmission of HIV (PMTCT) programme in 3 sites in South Africa, and the quality of infant feeding counselling across four countries, Botswana, Kenya, Malawi and Uganda . Implementation and outcome of PMTCT services were very different across the 3 sites. LÄS MER
