ABSTRACT
Physical activity (PA) promotion is a complex challenge, with the Global Action Plan on Physical Activity (GAPPA) endorsing a systems approach and recommending countries assess existing areas of progress which can be strengthened. This paper reports a process facilitating a systems approach for identifying current good practice and gaps for promoting PA in Ireland. Elements of participatory action research were enabled through 3 stages: (1) aligning examples of actions from Irish policy documents (n = 3) to the GAPPA, (2) workshop with stakeholders across multiple sectors, and (3) review of outputs. Data collected through the workshop were analyzed using a deductive thematic analysis guided by the GAPPA. The policy context in Ireland aligns closely to the GAPPA with the creation of Active Systems the most common strategic objective across policy documents. Forty participants (50% male) took part in the systems approach workshop, which after revision resulted in 80 examples of good practice and 121 actions for greater impact. A pragmatic and replicable process facilitating a systems approach was adopted and showed current Irish policy and practices align with the GAPPA "good practices." The process provides existing areas of progress which can be strengthened, as well as the policy opportunities and practice gaps.

An 80-year-old female, with a known periampullary giant duodenal diverticulum, presented to the emergency department with general deterioration. While not clinically icteric, her laboratory investigations revealed an obstructive jaundice. MRCP demonstrated mild distension of the gallbladder with several calculi. There was intra- and extra-hepatic biliary dilatation to the level of the ampulla. A giant fluid and air filled periampullary duodenal diverticulum measuring ~8 cm in the long axis was noted. The CBD was dilated to the level of this diverticulum and the cause of the patient's biliary dilatation and obstruction. A rare pancreaticobiliary complication of duodenal diverticula is Lemmel syndrome. Lemmel syndrome is defined as an obstructive jaundice caused by a periampullary duodenal diverticulum compressing the intra-pancreatic portion of the common bile duct with resultant dilatation of the extra- and intra-hepatic bile ducts. Recognition of this condition is important, as delayed diagnosis can result in unnecessary further investigations.
ABSTRACT
Electron transfer mechanisms in Shewanella loihica PV-4 viable biofilms formed at graphite electrodes were investigated in potentiostat-controlled electrochemical cells poised at oxidative potentials (0.2V vs. Ag/AgCl). Chronoamperometry (CA) showed a repeatable biofilm growth of S. loihica PV-4 on graphite electrode. CA, cyclic voltammetry (CV) and its first derivative shows that both direct electron transfer (DET) mediated electron transfer (MET) mechanism contributes to the overall anodic (oxidation) current. The maximum anodic current density recorded on graphite was 90 µA cm(-2). Fluorescence emission spectra shows increased concentration of quinone derivatives and riboflavin in the cell-free supernatant as the biofilm grows. Differential pulse voltammetry (DPV) show accumulation of riboflavin at the graphite interface, with the increase in incubation period. This is the first study to observe a gradual shift from DET to MET mechanism in viable S. loihica PV-4 biofilms.
