BioBanking and Molecular Resource Infrastructure in Sweden (BBMRI.se) was set up in 2009 in order to harmonise the standards and processes of biobanking. The present study is a qualitative narrative overview aimed at evaluating published studies on medical and/or biobank research infrastructure. Web of Science (WOS) and PubMed databases were searched to find studies on largescale medical research infrastructures. A total of 145 articles were found, but only merely 17 made it past the exclusion criteria. Eleven of the 17 articles listed first authors affiliated with European countries. Most of the articles discussed the need for “research infrastructures” while not addressing the subject in any detail. Consequently, this study concluded that there is a pressing need for deeper and more extensive multidisciplinary collaboration, especially on how research infrastructures are structured, managed, and branded.

Introduction: Helicobacter pylori (H. pylori) is a pathogen which is capable of colonizing the gastric mucosa and is associated with some pathological changes that may lead to dyspeptic manifestations. Recently, H. pylori was found to be present in the oral cavity and there was a growing body of evidence that the organism is linked to some dental diseases such as periodontitis and gingivitis. Materials and Method: In this study, 123 patients were investigated to explore the possible relationship between the presence of oral H. pylori and gastric dyspepsia. Patients were classified into oral disease group (viz. gingivitis and periodontitis) or gastric disease group (viz. gastritis, gastric ulcer, and duodenal ulcer). A third group had neither had oral nor gastric disease. Based on the presence or absence of H. pylori, patients were also classified as having either oral, gastric, or both oral and gastric organism. Some of the patients were neither having oral nor gastric infection. Results: 59 patients showed the presence of H. pylori in the gastro-duodenal area, 7 showed presence of oral H. pylori, whereas 18 patients showed H. pylori in both gastro- duodenal and oral specimens. Differences between groups were not statistically significant. Conclusions: Although there was a suggestion of a clinical and laboratory evidence of an association between the presence of oral H. pylori and the studied gastric diseases, this association was not statistically significant.

Hypoglycemia after bariatric surgery is currently recognized as a common post-surgical complication. Here we present two cases of post-surgical factitious hypoglycemia secondary to insulin administration. This report recommends comprehensive evaluation of post-bariatric hypoglycemia and highlights the potential self-harm behavior in patients undergoing bariatric procedures.
