Although obesity is associated with excess mortality and morbidity, mortality is lower in obese than in normal weight stroke patients (the obesity paradox). Studies now indicate that obesity is not associated with increased risk of recurrent stroke in the years after first stroke. We studied the association between body mass index (BMI) and stroke patient's risk of having a history of previous stroke (recurrent stroke).

Objective: Case management has since the 1970s been widely used to co-ordinate services for mental health patients. The methodology has expanded to support patients in many different types of conditions. This study is one of very few randomized trials on case management in a European setting. It examined the impact of case management on substance abuse and use of service after discharge from court-ordered institutional care. Methods: Court-ordered patients with substance abuse (n = 36) were randomly assigned to either strengths based case management or treatment-as-usual during 6 months in aftercare. Data was collected at intake, at conclusion of intervention and at 6 month's follow-up with a follow-up rate of 94%. Results: Case management interventions were well received by the patients with no drop-out during intervention. Patients with the support of a case manager seemed to sustain abstinence in a higher degree compared with treatment-as-usual but no differences were detected in regard to use of care. A subgroup analysis showed that patients with a continuous drug abuse did have access to care from both social welfare and hospital care systems. Conclusions: Case management may be useful in order to retain abstinence in aftercare following court-ordered treatment. The social welfare and hospital care systems seem to provide care irrespective of case manager intervention. The study design, interventions and assessments instruments were well received by patients but needs to be replicated with a larger population. Clinical implications: The 100% retention in the case management support group indicates that patients were satisfied with this type of intervention and the methodology seems to be useful in order to retain abstinence.

Patients are susceptible for knee osteoarthritis (KOA) with increasing age and obesity and KOA is expected to become a major disabling disease in the future. An important feature of KOA on magnetic resonance imaging (MRI) is changes in the subchondral bone, bone marrow lesions (BMLs), which are related to the future degeneration of the knee joint as well as prevalent clinical symptoms. The aim of this study was to investigate the changes in BMLs after a 16-week weight-loss period in obese subjects with KOA and relate changes in BMLs to the effects of weight-loss on clinical symptoms.

Injection therapy with glucocorticoids has been used since the 1950s as a treatment strategy for lateral epicondylitis (tennis elbow). Lately, several novel injection therapies have become available.

Centromere protein-F (CENP-F) is a large nuclear protein of 367 kDa, which is involved in multiple mitosis-related events such as proper assembly of the kinetochores, stabilization of heterochromatin, chromosome alignment and mitotic checkpoint signaling. Several studies have shown a correlation between CENP-F and cancer, e.g. the expression of CENP-F has been described to be upregulated in cancer cells. Furthermore, several studies have described a significant correlation between the expression of autoantibodies to CENP-F and cancer.

Cytokines are important in the understanding of the immune process in health and disease and are valuable indicators in diagnostics. Measurements of cytokines are based on immunometric methods, and it is important to understand possible pitfalls in these methods to produce reliable cytokine data. This paper focuses on obtaining optimal measurements when applying enzyme-linked immunosorbent assay (ELISA) or multiplex immunoassays (MIA). Cytokines are measured in serum or plasma, as well as in various other body fluids, all containing a series of antibodies and the possibility of interference from these. Some antibodies, such as heterophilic and human anti-animal antibodies, are able to interfere with all immunoassays, but the immunometric techniques are most prone to serious interference from this source. Another type, rheumatoid factor (RF) is a composite of different autoimmune antibodies which can be present in both blood and synovial fluid. RF is present in some arthritic diseases as well as in some other medical conditions. When present, especially RF IgM is known to interfere with the immunometric measurements. A possible and affordable solution to diminish this interference is PEG precipitation, but other efficient, but more expensive, methods, such as precipitation using Protein L or commercially available blocking agents, are also available. Interference of RF is at present not tested in all cytokine assays, but degree of interference from RF, human anti-animal and heterophilic antibodies, as well as from other possible disease-specific antibodies, must always be considered when developing and applying new assays for cytokine measurements.
