Management of patients with chronic kidney disease: a French medical centre database analysis.

OBJECTIVE(S): Chronic kidney disease (CKD) is an insidious disease that requires early nephroprotective measures to delay progression to end-stage kidney disease. The objective of this study was to describe the management of patients with CKD in primary care, including clinical and biological monitoring and prescribed treatments. A retrospective, single-centre study was conducted on adult patients who were treated in the Maison de Neufchâtel (France) between 2012 and 2017 at least once a year. The inclusion criteria were 2 estimated glomerular filtration rate (eGFR) measurements <60 mL/min more than 3 months apart. Two subgroups were constituted according to whether CKD was coded in the electronic medical records (EMRs). RESULTS: A total of 291 (6.7%, CI95% 5.9-7.4) patients with CKD were included. The mean eGFR was 51.0 ± 16.4 mL/min. Hypertension was the most frequent health problem reported (n = 93, 32%). Nephrotective agents were prescribed in 194 (66.7%) patients, non-steroidal anti-inflammatory drugs (NSAIDs) in 22 (8%) patients, and proton-pump inhibitors (PPIs) in 147 (47%) patients. CKD coding in EMRs was associated with dosage of natraemia (n = 34, 100%, P < 0.01), albuminuria (n = 20, 58%, P < 0.01), vitamin D (n = 14, 41%, P < 0.001), and phosphorus (n = 11, 32%, P < 0.001). Eighty-one patients (31.5%) with low eGFR without an entered code for CKD were prescribed an albuminuria dosage. Clinical monitoring could not be analysed due to poor coding. CONCLUSION: This pilot study reinforces the hypothesis that CKD is underscreened and undermanaged. More systematic coding of medical information in EMRs and further studies on medical centre databases should improve primary care practices.

Chronic kidney disease (CKD) is an insidious disease that requires early protective measures to delay progression to end-stage kidney disease. The aim of this study was to describe the management of patients with CKD in primary care. A study was conducted in France by analysing the medical records of adult patients between 2012 and 2017. Of 4,370 patients, 291 (6.7%) had CKD. Hypertension was the main associated medical history (32%) and was also known to be one of the main risk factors for CKD. Ninety-seven patients (33%) did not receive any medication indicated to protect the kidneys. Kidney-toxic drugs were widely prescribed, including PPIs in 47% of patients and NSAIDs in 8% of patients. Patients with a CKD note in their medical record had closer biological monitoring. This pilot study reinforces the hypothesis that CKD is underscreened and undermanaged. The coding of information in primary care and further studies on these databases should improve the practice of general practice.

dbgap2x: an R package to explore and extract data from the database of Genotypes and Phenotypes (dbGaP).

SUMMARY: Based on the Genomic Data Sharing Policy issued in August 2007, the National Institutes of Health (NIH) has supported several repositories such as the database of Genotypes and Phenotypes (dbGaP). dbGaP is an online repository that provides access to large-scale genetic and phenotypic datasets with more than 1000 studies. However, navigating the website and understanding the relationship between the studies are not easy tasks. Moreover, the decryption of the files is a complex procedure. In this study we propose the dbgap2x R package that covers a broad range of functions for searching dbGaP studies, exploring the characteristics of a study and easily decrypting the files from dbGaP. AVAILABILITY AND IMPLEMENTATION: dbgap2x is an R package with the code available at https://github.com/gversmee/dbgap2x. A containerized version including the package, a Jupyter server and with a Notebook example is available at https://hub.docker.com/r/gversmee/dbgap2x. SUPPLEMENTARY INFORMATION: Supplementary data are available at Bioinformatics online.

Impact of MaxZero™ needle-free connector on the incidence of central venous catheter-related infections in surgical intensive care unit.

BACKGROUND: Central venous catheter-related infections (CRIs) are a complication of central venous catheters in intensive care unit (ICU). Some needle-free connectors have been designed to decrease CRI, but there is a lack of data concerning their impact on infection. OBJECTIVES: The objective was to explore the impact of MaxZero™ connectors (BD; Franklin Lakes, US) on CRI in ICU. METHODS: Observational, pre-post design study (2011-2013 and 2014-2016) conducted in the surgical ICU of a tertiary care hospital (18 beds). Patients with a central venous catheter and a length of stay ≥48 h were included. The connectors replaced all disposable caps used on infusion stopcocks and ramps. The primary parameter was to compare the incidence of CRI between the "before" period and the "after" period. RESULTS: A total of 1633 patients were included (789 "before" and 844 "after"). There was no difference between groups concerning the global duration of catheterisation (12.5 ± 11.5 days vs. 12.1 ± 10.9 days). There were 61 CRIs before and 28 CRIs after the introduction of connectors; the incidence of CRI in the "before" group was 20.33 CRI/year (6.18 CRI per 1000 catheter-days) vs. 9.33 CRI/year (2.73 CRI per 1000 catheter-days) in the "after" group (incidence rate ratio = 0.44; 95% confidence interval = 0.28-0.68, p < 0.001). However, after a global analysis of the 6-year period, when adjusting for seasonal effect and pre-existing linear trend, the effect was no longer significant (adjusted incidence rate ratio = 0.57; 95% confidence interval = 0.24-1.35, p = 0.20). CONCLUSIONS: Our results do not allow us to conclude to a potential beneficial effect of MaxZero™ on CRI but are compatible with its prolonged and safe use in ICU. Only future prospective works will be able to confirm the value of these connectors for CRI prevention.

WikiMeSH: Multi Lingual MeSH Translations via Wikipedia.

OBJECTIVE: The aim of this paper is to propose an extended translation of the MeSH thesaurus based on Wikipedia pages. METHODS: A mapping was realized between each MeSH descriptor (preferred terms and synonyms) and corresponding Wikipedia pages. RESULTS: A tool called "WikiMeSH" has been developed. Among the top 20 languages of this study, seven have currently no MeSH translations: Arabic, Catalan, Farsi (Iran), Mandarin Chinese, Korean, Serbian, and Ukrainian. For these seven languages, WikiMeSH is proposing a translation for 47% for Arabic to 34% for Serbian. CONCLUSION: WikiMeSH is an interesting tool to translate the MeSH thesaurus and other health terminologies and ontologies based on a mapping to Wikipedia pages.
