  1. 21. Survival patterns and density-dependent processes in breeding mallards Anas platyrhynchos

    Författare :Gunnar Gunnarsson; Kjell Sjöberg; Johan Elmberg; Per Lundberg; Robert Clark; Högskolan Kristianstad; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; broods; dabbling ducks; density dependence; ducklings; experiments; models; mortality; nest predation; regulation; survival; Terrestrial ecology; Terrestrisk ekologi;

    Sammanfattning : Measuring and assessing vital rates such as births and deaths are prerequisites for understanding population dynamics. Vital rates may be affected by the density of individuals, even though the importance of density dependence on population dynamics has been debated for a long time. LÄS MER

  2. 22. Home Mechanical Ventilation in Sweden. Demography, Indications, Clinical Effects and Survival

    Författare :Michael Laub; allergologi och palliativ medicin Lungmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; home mechanical ventilation; Andningsorganen; Respiratory system; causes of death; selection criteria; clinical effects; prevalence; temporal changes; survival; Chronic respiratory failure hypoventilation;

    Sammanfattning : Home mechanical ventilation in patients with chronic respiratory failure secondary to several different diseases has become widely acceptable as the provision of ventilatory support can provide symptomatic relief and increase life expectancy. Aims: To study the selection criteria underlying the initiation of home mechanical ventilation and to quantify the effects of in relation to blood gases and lung function; to examine temporal changes in treatment prevalence in Sweden; to study survival and causes of death and demonstrate possible related impact factors.

  3. 23. Mortality and survival from childhood to old age in rural Ethiopia

    Författare :Mesganaw Fantahun; Ulf Högberg; Stig Wall; Peter Byass; Yemane Berhane; Thorkild Tylleskär; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mortality; survival; children; adults; elderly; cause of death; determinants; Ethiopia; Epidemiology; Epidemiologi;

    Sammanfattning : This thesis examines ways of establishing cause of death, assessing trends in mortality, and identifying factors that affect mortality and survival among the different population groups in rural and semi-urban Ethiopia. These data are important for health care planning; however, such vital data are unavailable in many developing countries. LÄS MER

  4. 24. Clinical and Biological Factors Related to Survival in Patients with Rectal Cancer

    Författare :Angeliki Kotti; Xiao-Feng Sun; Annica Holmqvist; Marie-Louise Lydrup; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Age; Radiotherapy; Rectal cancer; Skeletal muscle; SPARCL1; Statins; Survival; Visceral adipose tissue;

    Sammanfattning : Rectal cancer is a common malignancy within the gastrointestinal tract. Despite the advances in diagnosis and treatment of rectal cancer patients during the last decades, there are still many patients who die from their disease. LÄS MER

  5. 25. Loco-regional Treatment of Peritoneal Carcinomatosis: Survival, Morbidity and Quality of Life

    Författare :Johan Hansson; Haile Mahteme; Wilhelm Graf; Peter Nygren; Peter Naredi; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Peritoneal carcinomatosis; Cytoreductive surgery; Intraperitoneal chemotherapy; Survival; SPECT; Morbidity; Mortality; Quality of life; Surgery; Kirurgi; Oncology; onkologi;

    Sammanfattning : Peritoneal carcinomatosis (PC) is traditionally regarded as a terminal stage of disease with a poor prognosis and systemic chemotherapy is regarded as palliative treatment. In order to improve survival and even to achieve cure for selected patients with PC, cytoreductive surgery and intraperitoneal che-motherapy have been advocated. LÄS MER
