1. 11. Stochasticity in Biophysical Systems: Searching, Aging, and Spreading

   Författare :Lloyd Sanders; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anomalous diffusion; Single-file; Markov process; Epidemiology; First Passage Time;

   Sammanfattning : The role of stochasticity throughout many biophysical systems is of great importance. From evolution to foraging, from the spreading of viruses to cell fate, all hinge in one way or another on inherent stochasticity. LÄS MER

3. 12. Metabolomics, body composition and fracture

   Författare :Rui Zheng; Karl Michaëlsson; Harri Sievänen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Metabolomics; LC-MS; sample quality; cohort; body composition; fracture; Medicinsk vetenskap; Medical Science; Bioinformatics; Bioinformatik; Epidemiologi; Epidemiology; Orthopaedics; Ortopedi; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

   Sammanfattning : In this thesis, I evaluated the impact of pre-centrifugation sample management on the plasma metabolome, providing verification for the protocol used in a study where I applied metabolomics to better understand the role of body composition in fracture occurrence using a large population-based cohort.  In paper 1, I applied untargeted liquid chromatography-mass spectrometry (LC-MS) metabolomics analysis to plasma samples (n = 471) from healthy donors to predict and evaluate the effect of pre-centrifugation temperature and delay time on metabolomics data using a combination of random forest and generalized linear models.

4. 13. Maternal Mortality Then, Now, and Tomorrow : The Experience of Tigray Region, Northern Ethiopia

   Författare :Hagos Godefay Debeb; John Kinsman; Peter Byass; Afework Mulugeta; Wendy Graham; Bernt Lindtjoern; Umeå universitet; []
   Nyckelord :Maternal mortality; intervention; ambulance; family folder; case-control; cross-sectional survey; verbal autopsy; Tigray; Ethiopia; epidemiologi; Epidemiology;

   Sammanfattning : AbstractBackground: Maternal mortality is one of the most sensitive indicators of the health disparities between poorer and richer nations. It is also one of the most difficult health outcomes to measure reliably. In many settings, major challenges remain in terms of both measuring and reducing maternal mortality effectively. LÄS MER

5. 14. Spatial Analysis and Modeling for Health Applications

   Författare :Lars Skog; Yifang Ban; Matthew Smallman-Raynor; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sweden; spatial analysis; spatial modeling; spatio-temporal spread; epidemiology; pandemic; walkability; health; Russian influenza; Asian influenza; A H1N1 pdm09; GWM; climate factors;

   Sammanfattning : Despite the benefits of applying methods of geographic information science (GIScience), the use of such methods in health service planning and provision remains greatly underutilized. Spread of epidemic diseases is a constant threat to mankind and the globalization of the world increases the risk for global attacks from multi-resistant bacteria or deadly virus strains. LÄS MER

7. 15. Where are the world’s disease patterns heading? : The challenges of epidemiological transition

   Författare :Ailiana Santosa; Peter Byass; Ulf Högberg; Joacim Rocklöv; Sarah Wild; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; epidemiological transition; premature mortality; non-communicable disease; risk factors; Sweden; low-and middle-income countries; INDEPTH Network; Västerbotten Intervention Programme; Public health; folkhälsa;

   Sammanfattning : INTRODUCTION: Epidemiological transition theory, first postulated by Omran in 1971, provides a useful framework for understanding cause-specific mortality changes and may contribute usefully to predictions about cause-specific mortality. However, understandings of mortality transitions and associated epidemiological changes remain poorly defined for public health practitioners due to lack of evidence from low- and middle-income countries.
