ABSTRACT
INTRODUCTION: In the Netherlands, the total number of yearly measured lipid profiles exceeds 500,000. While lipid values are strongly affected by age and sex, until recently, no up-to-date age- and sex-specific lipid reference values were available. We describe the translation of big-cohort lipid data into accessible reference values, which can be easily incorporated in daily clinical practice. METHODS: Lipid values (total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides) from all healthy adults and children in the LifeLines cohort were used to generate age- and sex-specific percentiles. A combination of RStudio, Cascading Style Sheets and HyperText Markup Language was used to interactively display the percentiles in a responsive web layout. RESULTS: After exclusion of subjects reporting cardiovascular disease or lipid-lowering therapy at baseline, 141,611 subjects were included. On the website, input fields were created for age, sex and all main plasma lipids. Upon input of these values, corresponding percentiles are calculated, and output is displayed in a table and an interactive graph for each lipid. The website has been made available in both Dutch and English and can be accessed at www.lipidtools.com . CONCLUSION: We constructed the first searchable, national lipid reference value tool with graphical display in the Netherlands to use in screening for dyslipidaemias and to reduce the underuse of lipid-lowering therapy in Dutch primary prevention. This study illustrates that data collected in big-cohort studies can be made easily accessible with modern digital techniques and preludes the digital health revolution yet to come.
ABSTRACT
BACKGROUND: High-output enterocutaneous fistula or enterostomies can cause intestinal failure. There is a wide variety of options in medical management of patients with high output. AIM: To systematically review the literature on available pharmacotherapy to reduce output and to propose an algorithm for standard of care. METHODS: Relevant databases were systematically reviewed to identify studies on pharmacotherapy for reduction in (high-) output enterostomies or fistula. Randomised controlled trials and within subjects controlled prospective trials were included. An algorithm for standard of care was generated based on the outcomes of the systematic review. RESULTS: Two studies on proton pump inhibitors, six on anti-motility agents, three on histamine receptor antagonists, one on an α2- receptor agonist and eight on somatostatin (analogues) were included. One study examined a proton pump inhibitor and a histamine receptor antagonist within the same patients. Overall, we found evidence for the following medical therapies to be effective: omeprazole, loperamide and codeine, ranitidine and cimetidine. On the basis of these outcomes and clinical experience, we proposed an algorithm for standard of care which consists of high-dose proton pump inhibitors combined with high-dose loperamide as the first step followed by addition of codeine in case of insufficient output reduction. So far, there is insufficient evidence for the standard use of somatostatin (analogues). CONCLUSIONS: The available evidence on the efficacy of medication to reduce enterostomy or enterocutaneous fistula output is hampered by low quality studies. We propose an algorithm for standard of care output reduction in these patients.
