    Sammanfattning : This thesis, within the subfield of computer science known as computer vision, deals with the use of scale-space analysis in early low-level processing of visual information. The main contributions comprise the following five subjects:The formulation of a scale-space theory for discrete signals. LÄS MER

  2. 2. Mother, how are you? : Studies on self-rated health and childbirth experience

    Författare :Frida Viirman; Anna Wikman; Susanne Hesselman; Agneta Skoog Svanberg; Inger Sundström Poromaa; Mirjam Lukasse; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Self-rated health; SRH; Small for Gestational Age; SGA; Preterm; Stillbirth; Pregnancy; Childbirth; Labour; Delivery; Childbirth Experience; Psychological Birth Trauma; Visual Analogue Scale; VAS; Numeric Rating Scale; NRS; Single-item; Childbirth Experience Questionnaire; CEQ 2; Midwifery; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Pregnancy and childbirth are characterised by emotional and physical changes, which can affect the mother’s mental health postpartum, as well as the infant. One step towards alleviating adverse consequences is to measure health status and childbirth experience. LÄS MER

  3. 3. Pain treatment after surgery : With special reference to patient-controlled analgesia, early extubation and the use of paracetamol

    Författare :Pia Holmér Pettersson; Karolinska Institutet; Karolinska Institutet; Stockholm Karolinska Institutet; []
    Nyckelord :acetaminophen; analgesia; patient-controlled; analgesics; day surgery; heart surgery; opioid; ketobemidone; pain measurement; pain; postoperative; paracetamol; postoperative nausea and vomiting; visual analogue scale; Acetaminophen; analgesia; patient-controlled; analgesics; day surgery; heart surgery; opioid; ketobemidone; pain measurement; pain; postoperative; paracetamol; postoperative nausea and vomiting; visual analogue scale;

    Sammanfattning : The introduction of general anaesthesia eliminated pain during surgical operations. After surgery, however, pain and postoperative nausea and vomiting (PONV) have remained a persistent problem for many patients. The need for analgesics varies widely among patients, therefore standardised treatment protocols are often insufficient pain treatment. LÄS MER

  4. 4. Nonparametric tests for comparing two treatments by using ordinal data

    Författare :Helen Wahlström; Elisabeth Svensson; Jan Lanke; Sture Holm; Örebro universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Statistik; change; clinical trial; Monte Carlo; ordered categorical data; paired data; permutation test; Pitman efficiency; power; stratification; ties; visual analogue scale; Wilcoxon-Mann-Whitney statistic; statistik; Statistics; Statistik; Statistics; Statistik;

    Sammanfattning : This thesis concerns four nonparametric tests for comparing two treatments in a randomized controlled clinical trial when the main response variable generates discrete or continuous ordinal data and measurements are made at baseline and follow-up. In the Wilcoxon-Mann-Whitney test (WMW) the baseline values are not taken into account at all, but in the other three tests both baseline and follow-up values are used. LÄS MER

  5. 5. Women's experience of pain and pain relief in assisted reproductive technology

    Författare :Ann-Louise Gejervall; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :oocyte retrieval; pain relief; randomized controlled trial; pain; fertilization rate; embryo development; Visual Analogue Scale;

    Sammanfattning : The overall aim of this thesis was to evaluate and compare different methods for pain relief during oocyte retrieval and to study women’s expectations and experiences of pain during oocyte retrieval in conjunction with in vitro fertilization. Paper I, an open prospective randomized controlled trial, including 160 women had the primary aims of comparing the pain relieving effects of electro-acupuncture and conventional analgesia, comprising opiates, in conjunction with oocyte retrieval, and to compare post-operative well-being between groups.
