How patients understand depression associated with chronic physical disease - A systematic review

Background: Clinicians are encouraged to screen people with chronic physical illness for depression. Screening alone may not improve outcomes, especially if the process is incompatible with patient beliefs. The aim of this research is to understand peoples beliefs about depression, particularly in the presence of chronic physical disease. Methods: A mixed method systematic review involving a thematic analysis of qualitative studies and quantitative studies of beliefs held by people with current depressive symptoms. MEDLINE, EMBASE, PSYCHINFO, CINAHL, BIOSIS, Web of Science, The Cochrane Library, UKCRN portfolio, National Research Register Archive, Clinicaltrials.gov and OpenSIGLE were searched from database inception to 31st December 2010. A narrative synthesis of qualitative and quantitative data, based initially upon illness representations and extended to include other themes not compatible with that framework. Results: A range of clinically relevant beliefs was identified from 65 studies including the difficulty in labeling depression, complex causal factors instead of the biological model, the roles of different treatments and negative views about the consequences of depression. We found other important themes less related to ideas about illness: the existence of a self-sustaining depression spiral; depression as an existential state; the ambiguous status of suicidal thinking; and the role of stigma and blame in depression. Conclusions: Approaches to detection of depression in physical illness need to be receptive to the range of beliefs held by patients. Patient beliefs have implications for engagement with depression screening

Liver transplantation for HBV-related cirrhosis in Europe: an ELTR study on evolution and outcomes.

BACKGROUND & AIMS: HBV-related chronic liver disease is one of the most common indications for liver transplantation (LT) in Europe. The ELTR database was used to evaluate outcomes and evolution over 20 years (01/1988 and 12/2010). METHODS: HBV transplanted patients were analysed according to indication for LT: decompensated cirrhosis (HBVdec) or hepatocellular carcinoma (HBV/HCC). These groups were compared with co-infected patients HBV/HDV (HBDV), HBV/HCV (HBCV), HBV/HDV/HCV (HBDCV); n = 16,664 and with HCV patients (n = 2452) according to LT indication. RESULTS: 5912 patients were transplanted for HBV (78% HBVdec, 22% HBV/HCC), with HBV/HCC patients who increased from 15.8% in 1988-1995 to 29.6% in 2006-2010 (p < 0.001). In HBVdec patients, 1, 3, 5, and 10 year patient and graft survival was 83%, 78%, 75%, 68%, and 80%, 74%, 71%, 64%, respectively, significantly better than HBV/HCC (84%, 73%, 68%, 61%, and 81%, 70%, 65%, 58% respectively; p = 0.001 and p = 0.026). In 2006-2010 patient and graft survival significantly improved compared to 1988-1995, both for HBVdec and HBV/HCC (each p < 0.001). A better patient and graft survival was seen in HBV/HCC patients with HBV-DNA(-) compared to HBV-DNA(+) at the time of LT (p < 0.001). Disease recurrence, as cause of death/graft loss, was significantly reduced in recent years compared to the past: currently <1% for HBVdec and 3% for HBV/HCC. CONCLUSIONS: Outcomes of LT for HBV have improved in recent years, with disease recurrence being no longer a significant cause of death/graft loss. HBV-DNA at the time of LT seems to influence survival only in HBV/HCC patients

Factors that predict response of patients with hepatitis C virus infection to boceprevir.

The CC polymorphism at IL-28B rs12979860 is associated with response to triple therapy and can identify candidates for shorter treatment durations. A ≥ 1 log(10) decrease in HCV RNA at week 4 of therapy is the strongest predictor of a SVR, regardless of polymorphisms in IL-28B

Femoral Head Size and Wear of Highly Cross-linked Polyethylene at 5 to 8 Years

Wear of highly cross-linked polyethylene is reportedly independent of head size. To confirm that observation we asked in our population whether head size related to wear with one type of electron beam highly cross-linked polyethylene. Of 146 hips implanted, we evaluated complete clinical and radiographic data for 90 patients (102 hips or 70%). The minimum followup was 5 years (mean, 5.7 years; range, 5–8 years). The head size was selected intraoperatively based on the size of the acetabular component and presumed risk of dislocation. Polyethylene wear measurements were performed in one experienced laboratory using the method of Martell et al. There was no hip with pelvic or femoral osteolysis. The median linear wear rate was 0.028 mm/year (mean, 0.04 mm/year), and the median volumetric wear rate was 25.6 mm3/year (mean, 80.5 mm3/year). Median total volumetric wear was 41.0 mm3 (mean, 98.5 mm3). We found no association between femoral head size and the linear wear rate, but observed an association between larger (36- and 40-mm) head size and volumetric wear rate and total volumetric wear. Although the linear wear rate of polyethylene was not related to femoral head diameter, there was greater volumetric wear (156.6 mm3/year) with the 36- and 40-mm heads. Pending long-term studies of large head sizes, we advise caution in using larger femoral heads in young or active patients and in those with a low risk of dislocation

Do large femoral heads reduce the risks of impingement in total hip arthroplasty with optimal and non-optimal cup positioning?

The purpose of this study was to assess whether large femoral heads (36–38 mm) improve the range of motion in total hip arthroplasty compared to standard (28–32 mm) femoral heads in the presence of optimal and non-optimal cup positioning. A mathematical model of the hip joint was generated by using a laser scan of a dried cadaveric hip. The range of motion was assessed with a cup inclination and anteversion of reference and with non-optimal cup positions. Large femoral heads increased the range of motion, compared to the 28-mm femoral head, in the presence of a hip prosthesis correctly implanted and even more so in the presence of non-optimal cup positioning. However, with respect to the 32-mm femoral head, large femoral heads showed limited benefits both in the presence of optimal and non-optimal cup positioning
