OverviewPancreatic cancer is one of the most common causes of cancer-related death among men and women in the United States. Abstract Ductal adenocarcinoma and its variants account for most pancreatic malignancies. High-quality multiphase imaging can help to preoperatively distinguish between patients eligible for resection with curative intent and those with unresectable disease. Systemic therapy is used in the neoadjuvant or adjuvant pancreatic cancer setting, as well as in the management of locally advanced unresectable and metastatic disease. Clinical trials are critical for making progress in treatment of pancreatic cancer. The NCCN Guidelines for Pancreatic Adenocarcinoma focus on diagnosis and treatment with systemic therapy, radiation therapy, and surgical resection.

Zyxin is an evolutionarily conserved protein that is concentrated at sites of cell adhesion, where it associates with members of the Enabled (Ena)/vasodilator-stimulated phosphoprotein (VASP) family of cytoskeletal regulators and is postulated to play a role in cytoskeletal dynamics and signaling. Zyxin transcripts are detected throughout murine embryonic development, and the protein is widely expressed in adults. Here we used a reverse genetic approach to examine the consequences of loss of zyxin function in the mouse. Mice that lack zyxin function are viable and fertile and display no obvious histological abnormalities in any of the organs examined. Because zyxin contributes to the localization of Ena/VASP family members at certain subcellular locations, we carefully examined the zyxin ؊/؊ mice for evidence of defects that have been observed when Ena/VASP proteins are compromised in the mouse. Specifically, we evaluated blood platelet function, nervous system development, and skin architecture but did not detect any defects in these systems. Zyxin is the founding member of a family of proteins that also includes the lipoma preferred partner (LPP) and thyroid receptor-interacting protein 6 (TRIP6). These zyxin family members display patterns of expression that significantly overlap that of zyxin. Western blot analysis indicates that there is no detectable upregulation of either LPP or TRIP6 expression in tissues derived from zyxin-null mice. Because zyxin family members may have overlapping functions, a comprehensive understanding of the role of these proteins in the mouse will require the generation of compound mutations in which multiple zyxin family members are simultaneously compromised.

BackgroundFibromyalgia is characterised by chronic musculoskeletal pain and multiple symptoms including fatigue, multidimensional function impairment, sleep disturbance and tenderness. Along with pain and fatigue, non-restorative sleep is a core symptom of fibromyalgia. Sodium oxybate (SXB) is thought to reduce non-restorative sleep abnormalities. This study evaluated effects of SXB on fibromyalgia-related pain and other symptoms.Methods573 patients with fibromyalgia according to 1990 American College of Rheumatology criteria were enrolled at 108 centres in eight countries. Subjects were randomly assigned to placebo, SXB 4.5 g/night or SXB 6 g/night. The primary efficacy endpoint was the proportion of subjects with ≥30% reduction in pain visual analogue scale from baseline to treatment end. Other efficacy assessments included function, sleep quality, effect of sleep on function, fatigue, tenderness, health-related quality of life and subject's impression of change in overall wellbeing.ResultsSignificant improvements in pain, sleep and other symptoms associated with fibromyalgia were seen in SXB treated subjects compared with placebo. The proportion of subjects with ≥30% pain reduction was 42.0% for SXB4.5 g/night (p=0.002) and 51.4% for SXB6 g/night (p<0.001) versus 26.8% for placebo. Quality of sleep (Jenkins sleep scale) improved by 20% for SXB4.5 g/night (p≤0.001) and 25% for SXB6 g/night (p≤0.001) versus 0.5% for placebo. Adverse events with an incidence ≥5% and twice placebo were nausea, dizziness, vomiting, insomnia, anxiety, somnolence, fatigue, muscle spasms and peripheral oedema.ConclusionThese results, combined with findings from previous phase 2 and 3 studies, provide supportive evidence that SXB therapy affordsimportant benefits across multiple symptoms in subjects with fibromyalgia.
