   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

3. 22. Hospital length stay : register-based studies on breast cancer surgery

   Författare :Rikard Lindqvist; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Length of stay; breast cancer; breast surgery; social factors;

   Sammanfattning : The present investigation focused on three main questions: what factors can determine length of stay for primary surgery for breast cancer? Can these factors be attributed to the decreasing trend in mean length of stay for primary breast-cancer surgery? And can there be any adverse effect of declining length of stay, such as prolonged sick leave, following breast-cancer surgery? For the four studies of the thesis, routinely collected data was used. In study I the Swedish Hospital Discharge Register was used to describe the trend in mean length of stay of women surgically treated for breast cancer and to investigate the effect of the increasing use of breast-conserving surgery on the decreasing trend in mean length of stay.

4. 23. Human factors in mechanized cut-to-length forest operations

   Författare :Carola Häggström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Although forest operations research has a more than 50-year-long tradition in the field of human factors, there is a current decline in resources put on continuous and systematic human factors research. Therefore, the overall aim of this thesis was to contribute new knowledge on working conditions in mechanized cut-to-length logging operations and their relationship to system performance. LÄS MER

5. 24. Leg length discrepancy and femoral offset after total hip arthroplasty : clinical and radiological studies

   Författare :Sarwar Mahmood; Arkan Sayed-Noor; Sead Crnalic; Gösta Ullmark; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Total hip arthroplasty; leg flength discrepancy; femoral offset; WOMAC; quality of life; complication; radiographic measurements; acetabular cup; inclination; anteversion; Orthopaedics; ortopedi;

   Sammanfattning : Every year, about 1 million patients worldwide and 16000 patients in Sweden undergo total hip arthroplasty (THA). This surgical intervention is considered a successful, safe and cost-effective procedure to regain pain-free mobility and restore hip joint function in patients suffering from severe hip joint disease or trauma.
