1. 36. Accidental hypothermia and local cold injury : physiological and epidemiological studies on risk

   Författare :Helge Brändström; Michael Haney; Urban Wiklund; Anders Eriksson; Karl-Axel Ängquist; Ola Winsö; Sigridur Kalman; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cold-related injuries; hypothermia; frostbite; cold adaptation; rewarming; autonomic nervous system; heart rate variability;

   Sammanfattning : Background: (Papers I and II) The objectives were to first determine incidence and contributing factors to cold-related injuries in northern Sweden, both those that led to hospitalization and those that led to fatality.  (Papers III and IV) A further aim was to assess post-cooling hand-rewarming responses and effects of training in a cold environment, both on fingertip rewarming and on function of the autonomic nervous system, to evaluate if there was adaptation related to prolonged occupational cold exposure.

3. 37. Changing to third party logistics

   Författare :Magnus Lindskog; Mats Abrahamsson; Helge Virum; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Third party logistics; Change; Process; Outsourcing; Business studies; Företagsekonomi;

   Sammanfattning : Third party logistics (TPL), the procurement of an integrated set of logistics services in a long-term relationship between a shipper (goods owner) and a service provider, is today a viable option for how companies carry out their logistics activities. Very little has been written on implementation or change issues in a TPL setting; these issues are identified as important, but not elaborated. LÄS MER

4. 38. Genetic studies of congenital upper limb anomalies

   Författare :Tobias Laurell; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The overall aim of the work reported in this thesis is to improve epidemiological and genetic knowledge of congenital upper limb anomalies (CULA). To accomplish the specific aims of each paper several different methods and approaches have been used such as register studies, array comparative genome hybridization, Sanger sequencing, exome sequencing and functional studies using Lacz enhancer assay, Zebrafish morpholinos and computational transcription factor binding site prediction.

5. 39. Real-world studies on B-cell malignancies

   Författare :Anna Asklid; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Randomized controlled trials remain the preferred way of evaluating new treatments. However, in studies on malignancies, trial data may not always be sufficient to address the requirements of health care providers and regulatory agencies regarding recommendations as patients are strictly selected through inclusion- and exclusion criteria.

7. 40. Cholecystectomy : studies on surgical methods, incidence and economy

   Författare :Axel Ros; Ulf Haglund; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : After almost a century without change in the surgical care of gallstone disease since the first cholecystectomy in 1882, a profound change in surgical treatment of gallstones has taken place over the last three decades with the introduction of endoscopic sphincterotomy for treatment of bile duct stones (EST), minilaparotomy cholecystectomy (MC), and laparoscopic cholecystectomy (LC). The epidemiology of gallstone surgery has changed since these minimally invasive procedures were introduced. LÄS MER
