  1. 1. Vaginal prolapse surgery : an epidemiological perspective : studies of native tissue repair versus implants, surgeons´ practical experiences and five year follow-up in the swedish national quality register for gynecological surgery

    Författare :Emil Nüssler; Mats Löfgren; Marie Bixo; Martin Stjernquist; Umeå universitet; []
    Nyckelord :pelvic organ prolapse; Kaplan-Meier curves; long-term follow-up; quality register; questionnaire; patient reported outcome; cystocele; rectocele; colporrhaphy; non-absorbable mesh; surgical experience; hälso- och sjukvårdsforskning; health services research; Obstetrics and Gynaecology; obstetrik och gynekologi;

    Sammanfattning : Background: Pelvic organ prolapse (POP) is a common condition that impacts on quality of life for many women. The mean age of Swedish women operated for POP is 60 years, and with a life expectancy of approximately 84 years this means that the average patient will live 24 years subsequent to the operation.

  2. 2. Applications of Vectorcardiography for Diagnosis and Risk Stratification in Subpopulations at Risk for Life-Threatening Arrhythmias

    Författare :Daniel Cortez; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vectorcardiography; atrial depolarization; ventricular depolarization repolarization;

    Sammanfattning : Introduction: Vectorcardiography, or 3-dimensional electrocardiography is a tool which can be used to identify subtle changes in the electrical forces of the heart, and which can be applied to atrial depolarization, ventricular depolarization and ventricular repolarization for prognostic and diagostic purposes. Methods: Kor’s regression-related and quasi orthogonal methods was used to derive vectorcardiographic parameters from the 12-lead electrocardiogram and applied to a cohort of cryptogenic stroke patients to assess atrial fibrillation, hypertrophic cardiomyopathy patients to assess for ventricular arrhythmias, applied with right-precordial directed quasi orthogonal method to arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVC/D) patients for diagnosis, and applied to ventricular repolarization only to patients with genotype-positive/phenotype-negative Long QT2 syndrome (KNCH2 mutation) to assess for cardiac events.

  3. 3. Tissue remodelling proteases as prognostic factors in colon and rectal cancer

    Författare :Marcus Langenskiöld; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :extracelluar matrix; survival; staging; colorectal cancer; mucosa; stroma;

    Sammanfattning : Background: Colorectal cancer is the third most common cancer in Sweden and the main treatment is surgery. The TNM classification is the principal staging tool, although insufficient in identifying all patients with poor survival. LÄS MER

  4. 4. Chronic limb-threatening ischaemia - Prognosis after intervention

    Författare :Erik Baubeta Fridh; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amputation; arterial occlusive disease; atherosclerosis; magnetic resonance angiography; mortality; peripheral arterial disease; comorbidity;

    Sammanfattning : Introduction: Lower-extremity arterial disease (LEAD) is a major health problem worldwide. Chronic limb-threatening ischaemia (CLTI) is the most severe manifestation of LEAD. Open or endovascular recanalization is recommended for most patients with CLTI. LÄS MER

  5. 5. Acute lung injury : incidence and predictors of outcome with special reference to inhaled nitric oxide

    Författare :Owe Luhr; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Respiratory distress syndrome; Adult; -drug-therapy; -mortality; Treatment; -outcome; Nitric oxide; therapeutic-use; administration-and-dosage; -adverse effects; Mutagenicity; tests; Chromosome aberrations; Risk factors; Logistic models; Prospective studies.;

    Sammanfattning : This work started out as a critical examination of the initial clinical experiences with inhalation of nitric oxide (INO) to patients with acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) in Scandinavia 1991-1994. During this examination, we found that epidemiological data and prognostic factors were lacking in Scandinavia for these patient groups, making it difficult to evaluate new therapies. LÄS MER
