Combining proactive transcranial stimulation and cardiac biofeedback to substantially manage harmful stress effects

Schlatter S, Guillot A, Schmidt L, Mura M, Trama R, Di Rienzo F, Lilot M, Debarnot U.

Background: Previous studies have identified the dorsolateral prefrontal cortex (dlPFC) as a core region in cognitive emotional regulation. Transcranial direct current stimulations of the dlPFC (tDCS) and heart-rate variability biofeedback (BFB) are known to regulate emotional processes. However, the effect of these interventions applied either alone or concomitantly during an anticipatory stress remains unexplored.

Objective: The study investigated the effect of anodal tDCS and BFB, alone or combined, on psychophysiological stress responses and cognitive functioning.

[Algorithms to identify chronic inflammatory rheumatism and psoriasis in medico-administrative databases: A review of the literature].

B Castagné, M Viprey, P Caillet-Pascal, M Belhassen, G Desjeux, S Bailly, C Estellat, M Soubrier, A M Schott, groupe REDSIAM. 

Background: We aimed to describe and discuss the algorithms used to identify chronic inflammatory rheumatisms and psoriasis in medico-administrative databases.

Methods: We performed a literature review on the Medline database of articles published up to 31 January 2018. Our inclusion criteria were: original articles using medico-administrative databases in accordance with the International Classification of Diseases, version 10 (ICD-10) and concerning rheumatoid arthritis (RA) or ankylosing spondylitis (AS) or psoriatic arthritis (PsoA) or Psoriasis (Pso). Our exclusion criteria were: letters to the editor, commentaries on published articles, studies using codes other than those of the ICD or a previous version.


Hospital Length of Stay Prediction Methods: A Systematic Review.

Lequertier V, Wang T, Fondrevelle J, Augusto V, Duclos A.

Objective: This systematic review sought to establish a picture of length of stay (LOS) prediction methods based on available hospital data and study protocols designed to measure their performance.

Materials and methods: An English literature search was done relative to hospital LOS prediction from 1972 to September 2019 according to the PRISMA guidelines. Articles were retrieved from PubMed, ScienceDirect, and arXiv databases. Information were extracted from the included papers according to a standardized assessment of population setting and study sample, data sources and input variables, LOS prediction methods, validation study design, and performance evaluation metrics.

Pretransplant Comprehensive Geriatric Assessment in Older Patients with Advanced Chronic Kidney Disease.

Novais T, Pongan E, Gervais F, Coste MH, Morelon E, Krolak-Salmon P, Vernaudon J.

Background : increasing numbers of older people are undergoing vascular surgery. Preoperative comprehensive geriatric assessment and optimisation (CGA) reduces postoperative complications and length of hospital stay. Establishing CGA-based perioperative services requires health economic evaluation prior to implementation. Through a modelling-based economic evaluation, using data from a single site clinical trial, this study evaluates whether CGA is a cost-effective alternative to standard preoperative assessment for older patients undergoing elective arterial surgery.

Methods : an economic evaluation, using decision-analytic modelling, comparing preoperative CGA and optimisation with standard preoperative care, was undertaken in older patients undergoing elective arterial surgery. The incremental net health benefit of CGA, expressed in terms of quality-adjusted life-years (QALYs), was used to evaluate cost-effectiveness.
