1. 1. The Substituted Judgment Standard. Studies on the Ethics of Surrogate Decision Making

   Författare :Linus Broström; Medicinsk etik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Systematic philosophy; Medicin människa och djur ; Medicine human and vertebrates ; hypothetical consent; autonomy; incompetence; surrogate accuracy; surrogate decision making; substituted judgment; ethics; aesthetics; metaphysics; epistemology; ideology; Systematisk filosofi; etik; estetik; metafysik; kunskapsteori; ideologi;

   Sammanfattning : Patients who are incompetent need a surrogate decision maker to make treatment decisons on their behalf. One of the main ethical questions that arise in this context is what standard ought to govern such decision making. LÄS MER

3. 2. Challenges of transnational parenthood : Exploring different perspectives of surrogacy in Sweden and India

   Författare :Anna Arvidsson; Birgitta Essén; Sara Johnsdotter; Pernilla Ouis; Karen Hvidtfeldt Madsen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transnational surrogacy; Surrogacy; Assisted reproduction; Commissioning parents; Legal parenthood; Social workers; Exploitation; Surrogate; Motherhood; Kinship; Social constructionism; Reproductive Justice; Sweden; India; Assam; Medicinsk vetenskap; Medical Science;

   Sammanfattning : Transnational surrogacy challenges traditional norms of parenthood, especially motherhood; additionally, it is viewed as the exploitation of poor women. The overall aim of this thesis was to shed light on the consequences of an unregulated situation on surrogacy in the Swedish and Indian contexts, and to give different perspectives on surrogacy and the surrogate.

4. 3. Evolving geriatric anthropometrics- an interplay with lifestyle changes, birth cohort effects, and survival implications. : Results from the general population study, “Good Aging in Skåne,” Sweden

   Författare :Nivetha Natarajan Gavriilidou; Geriatrik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anthropometrics; BMI misclassification; measurement; error correction; prediction equation; surrogate; survival; lifestyle; birth cohort; Swedish elderly; assessment;

   Sammanfattning : There is a rising proportion of aging population worldwide. The high vulnerability of older adults to morbidity and mortality introduces an enormous health and economic burden to themselves and the society. The established leading cause of death among older adults is due to chronic and vascular diseases. LÄS MER

5. 4. Patient Positioning in Radiotherapy Using Body Surface Scanning

   Författare :Kenneth Wikström; Anders Ahnesjö; Sven Bäck; Uppsala universitet; []
