    Sammanfattning : Cancer is one of the most common causes of death worldwide. When given optimal treatment, however, the risk of severe illness may greatly be reduced. Determining optimal treatment in turn requires evaluation of disease progression and response to potential, previous treatment. LÄS MER

  5. 4. Erfarenheter av vårdmiljön hos vuxna patienter med autismspektrumtillstånd

    Uppsats för yrkesexamina på grundnivå, Högskolan Väst/Institutionen för hälsovetenskap

    Författare :Jimmy Lohamre; Simon Rickard Lundgren; [2024]
    Nyckelord :Anxiety; autism spectrum disorders; communication; environment; experiences;

    Sammanfattning : Autism spectrum disorder is a diagnosis that involves difficulties with sensory sensitivity, communication, and social interaction. This condition means that the physical and psychosocial care environment can be experienced as difficult to manage. LÄS MER
