  2. 1. Vacuum-assisted closure in cardiac surgery - clinical outcome and vascular effects

    Author : Johan Sjögren; Thoraxkirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Surgery; Kardiovaskulära systemet; Cardiovascular system; Infektioner; Infections; endothelium; vascular; central hemodynamics; risk factors; long-term survival; mortality; wound closure; cardiac surgery; vacuum-assisted closure; poststernotomy mediastinitis; traumatology; Kirurgi; ortopedi; traumatologi;

    Abstract : The aim of this research was to clinically and experimentally evaluate the use of vacuum-assisted closure in poststernotomy mediastinitis after cardiac surgery. Vacuum-assisted closure (VAC) is a new wound-healing therapy based on the application of a local negative pressure to the wound. READ MORE

  4. 2. Vacuum-Assisted Closure Therapy - A new Treatment Modality in Poststernotomy Mediastinitis

    Author : Ronny Gustafsson; Thoraxkirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Surgery; Infektioner; Infections; Mortality; Lactate; Wound Healing; Respiration; Oxygenation; Circulation; Vacuum-assisted Closure; Mediastinitis; traumatology; Cardiac Surgery; Kirurgi; ortopedi; traumatologi;

    Abstract : Poststernotomy mediastinitis is a devastating complication associated with median sternotomy, which occurs mainly after cardiac surgery. The optimal treatment is still controversial. READ MORE

  5. 3. Vacuum-Assisted Closure Therapy after Cardiac Surgery. Sternal Stability, Cost of Care, Learning Curve and Hemodynamic Outcome

    Author : Arash Mokhtari; Thoraxkirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Health economics; Vacuum-assisted closure; Sternum; Mediastinitis; Deep sternal wound infection; Cardiac surgery; Wound healing; Hemodynamics; Wound closure;

    Abstract : Deep sternal wound infection (DSWI) following cardiothoracic surgery is a rare but potentially life-threatening complication with high morbidity and mortality. DSWI is associated with a significant increase in the length of hospital stay and the cost of hospitalization. The socioeconomic impact of DSWI is considerable. READ MORE

  6. 4. Synthesis of functional degradable polymers by radical ring-opening polymerization

    Author : Jenny Undin; Ann-Christine Albertsson; Mats Johansson; Monica Ek; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tissue engineering; ring-opening polymerization; 2; 2´-azoisobutyronitrile; cyclic ketene acetals; 2-methylene- 1; 3; 6-trioxocane; 2-methylene- 1; 3-dioxepane; vinyl acetate; coopolymerization;

    Abstract : The increased demand for understanding cell-material interactions and subsequently create personalized implants for tissue engineering has resulted in an increased interest in developing new monomers with functional groups. The focus of the work presented in this thesis has been on the synthesis of functional monomers and the polymerization of these into functional amorphous aliphatic polyesters. READ MORE

  7. 5. Scots pine (Pinus sylvestris L.) sapwood modification by vinyl acetate-epoxidized plant oil copolymer : precursor syntheses, characterization, modified wood properties and durability

    Author : Shengzhen Cai; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : A new bio-based formulation consisting of plant oil and vinyl acetate was developed for wood modification aiming at improving some of the material’s properties. In–situ epoxidation of linseed oil (LO) and soybean oil (SO) was carried out at different times with purpose of preparing epoxidized oils with various epoxy content. READ MORE
