Q: The aim of this study was to assess the effect of the implementation of evidence-based guidelines and subsequent feedback to surgeons in the management of acute pancreatitis.', 'An evidence-based Pancreatitis Proforma was developed. Data were prospectively recorded (01/06/2005-30/09/2007). Audit feedback (AFB) was performed at 9 months. A final analysis was performed comparing outcomes pre- and post-audit feedback.', '372 patients were included. Median age (range) was 57 (12-96) years. 168 (45.2%) patients were admitted pre-AFB. Post-AFB, there was a significant increase in the number of patients whose diagnosis was made within 48 hours (135/168 (80.4%) vs 189/204 (92.6%), p<0.001) and who underwent definitive treatment for mild biliary pancreatitis (33/61 (54.1%) vs 56/70 (80.0%), p=0.002). Post-AFB there was also a significant reduction in the number of computed tomography (CT) scans performed for patients with mild acute pancreatitis (23/85 (27.1%) vs 13/99 (13.1%), p=0.018). Mortality (9/168 (5.4%) vs 3/204 (1.4%), p=0.040) also decreased. On multivariate analysis, AFB was an independent factor for change in the use of CT scans (p=0.015) and management of patients with mild biliary pancreatitis (p=0.039).

Q: Accurate dosimetry was shown to be critical to achieve effective photodynamic therapy (PDT). This study aimed to assess the reliability of in vivo protoporphyrin IX (PpIX) fluorescence photobleaching as a predictive tool of the hexaminolevulinate PDT (HAL-PDT) response in a rat model of advanced ovarian cancer.', 'Intraperitoneal 10(6) NuTu 19 cells were injected in 26 female rats Fisher 344. Peritoneal carcinomatosis was obtained 26 days post-tumor induction. Four hours post-intraperitoneal HAL (Photocure ASA, Oslo, Norway) injection, a laparoscopic procedure (D-light AutoFluorescence system, Karl Storz endoscope, Tuttlingen, Germany) and a fluorescence examination were made for 22 rats. The first group (LASER group, n=26) was illuminated with laser light using a 532 nm KTP laser (Laser Quantum, Stockport, UK) on 1 cm(2) surface at 45 J/cm(2). The second group (NO LASER group, n=26) served as controls. Biopsies were taken 24 hours after PDT. Semi-quantitative histology was performed and necrosis value was determined: 0--no necrosis to 4--full necrosis. Fluorescence was monitored before and after illumination on complete responders (NV=3-4; n=20) and non-responders (NV=0-2; n=6).', 'High PpIX photobleaching corresponded with complete responders whereas low photobleaching corresponded with non-responders (P<0.05). A direct linear correlation was shown between photobleaching and necrosis (R(2)=0.89).

Q: The aim of this study was to investigate whether 14-3-3η, a specific isoform of a family of proteins regulating processes such as cellular signalling, activates cell-signalling pathways and induces factors known to contribute to the pathophysiology of rheumatoid arthritis (RA). We also investigated whether 14-3-3η is associated with more severe disease in both early and established RA.', 'We investigated the effect of 14-3-3η on the activation of RA-relevant signalling cascades and induction of proinflammatory mediators that contribute to the joint damage process. 14-3-3η titres from 33 patients with early RA (mean RA duration\u2009=\u20091.8 months) and from 40 patients with established RA were measured in serum drawn at the 3-year time point of the Behandel Strategieën study. The relationship between 14-3-3η titres and standard clinical variables was investigated by correlation analysis. The association with radiographic damage and radiographic progression over at least a 2-year period was investigated using univariate and multivariate regression analyses.', '14-3-3η activated selected members of the mitogen-activated protein kinase (MAPK) family, mainly extracellular regulated kinase 1/2 and c-Jun kinase, but not p38MAPK. Activation by 14-3-3η, using levels spanning the concentration range found in RA patient serum, resulted in the induction of inflammatory transcripts such as interleukin 1 (IL-1) and IL-6 and factors linked to the joint damage process, such as receptor activator of nuclear factor κB ligand and matrix metalloproteinase 1. Serum 14-3-3η correlated significantly with rheumatoid factor (RF) (r\u2009=\u20090.43) and anticitrullinated protein antibodies (ACPAs) (r\u2009=\u20090.31) in the early RA cohort, but not with C-reactive protein (CRP) or the Disease Activity Score in 28 joints in either cohort. Serum 14-3-3η concentrations were significantly higher in patients with radiographically assessed joint damage and in those who had radiographic progression. By multivariate analysis, we show that 14-3-3η complemented markers such as CRP, RF and ACPA in informing RA radiographic status and/or progression.
