   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; preterm delivery; transvaginal ultrasound; cervical length measurement; second trimester; prospective study; observational study; mass screening; reproducibility of results; inter-observer variation; intra-observer variation; data accuracy; quality control;

   Sammanfattning : Abstract Background: Short cervical length is a risk factor for preterm delivery (PTD) and screening of cervical length using transvaginal ultrasound in the second trimester is a proposed method to find women at risk Aims: To examine the potential value of routine measurement of cervical length in a Swedish population of women with singleton pregnancies in the prediction of PTD. To estimate inter- and intra-observer agreement and reliability of cervical length measurements. LÄS MER

4. 3. Genetic Determinants of Dyslipidemia

   Författare :Tibor V Varga; Genetisk och molekylär epidemiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetic epidemiology; Genetic polymorphism; dyslipidaemia; Cholesterol; Triglyceride; Genetic risk; genetic risk score; Single nucleotide polymorphism; Prediction; Gene-environment interactions; Randomized controlled trial; prospective cohort studies; Observational study; GLACIER Study; Diabetes Prevention Program;

   Sammanfattning : Dyslipidemia is a chronic deviation from normal blood lipid levels that can lead to atherosclerosis and other cardiovascular diseases; dyslipidemia and its sequelae are caused by the complex interplay of genetic and environmental factors. Although circulating concentrations of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (LDL-C) have a strong genetic underpinning, not much is known about the genetic factors that affect long-term deteriorations in lipid concentrations.

   Sammanfattning : This thesis is built around an observational study of a class at an elite school. The study follows the class through their upper secondary school education (ages 16-19), focusing on social science lessons. LÄS MER

7. 5. Design and analysis with observational data : Protocols and modeling with the aim of causal inference

   Författare :Paulina Jonéus; Mattias Nordin; Per Johansson; Jenny Häggström; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; observational studies; protocols guidelines; epidemiology; public health; prostate disease; Statistics; Statistik;

   Sammanfattning : This thesis consists of six papers that study the design and analysis with observational data.There is a growing interest in using real-world evidence (RWE) for regulatory purposes. The belief is that observational data can make drug developmentmore efficient and speed up patient access to new drugs. LÄS MER
