Periodontal pathogens of the interdental microbiota in a 3 months pregnant population with an intact periodontium

Steroid hormones and the oral microbiota of pregnant women both appear as cumulative risk factors for gingivitis. This cross-sectional study, using real-time PCR, investigated the composition and diversity of the microbiota in interdental spaces of 3 months pregnant women with intact periodontium according the 2018 EFP/AAP classification. Bacteria identified were belonged to the red (Porphyromonas gingivalis Treponema denticola, and Tanerella forsythia), orange (Fusobacterium nucleatum, Prevotella intermedia, Campylobacter rectus, and Parvimonas micra), and green (Eikenella corrodens and A. actinomycetencomitans) Socransky complexes. Approximatively 109.11 bacteria were counted per interdental space in pregnant women. Bacteria from the red complex represented 33.80% versus 62.81% for the orange group versus 3.39% for the green group of the total number spread over the 3 groups. Dietary habits and physical activity did not have a significant impact on interdental microbiota, although a decrease in the median amount of 9 periodontopathogens was observed when fruit and vegetable consumption increased. Pregnant women who brushed their teeth at least twice a day had lower counts of total bacteria and 9 periodontal pathogens than those who brushed less. In 3 months pregnant women at high risk of periodontal disease (>30% bleeding sites), the dendogram revealed 2 clusters of the 9 periodontopathogens. This provides further support for the “key pathogen” hypothesis, among which Porphyromonas gingivalis plays a key role, indicating that specific bacteria in limited quantities can influence the host immune system and convert the microbiota from symbiotic to dysbiotic to induce inflammatory disorder. As a result, this study reported that 3 months pregnant women with healthy periodontium had high levels of interdental bleeding and a dysbiotic microbiota with periodontal pathogens of the Socransky orange and red complexes. These subjects were therefore potentially at increased risk of developing periodontal disease and, consequently, an adverse pregnancy outcome. So, preventive oral prophylaxis measures, in particular individual interdental prophylaxis, should be implemented as soon as pregnancy is established

Inhaled morphine titration in the emergency department : modernization of the severe pain management in adults

Notre objectif était d’optimiser la prise en charge de la douleur aiguë sévère en médecine d’urgence. La titration morphinique intraveineuse qui fait actuellement référence doit se moderniser pour répondre aux nouveaux enjeux de la pratique en même temps que l’on doit garantir une balance bénéfice risque inchangée dans la lutte contre l’oligoanalgésie. Le travail décrit dans cette thèse, constitue une première étape d’évaluation d’une alternative nébulisée à la titration morphinique, à travers 3 études cliniques (AEROMORPH1, CLIN-AEROMORPH, EPIMORPH) et l’étude de son contexte dans la littérature. Des travaux chez le volontaire sain ont permis d’établir un mode opératoire avec une technique aérosol simple et accessible, de courte durée (5 min), que l’on peut répéter en titration (toutes les 10 min). Sa faisabilité est en voie d’être confirmée à grande échelle dans une étude multicentrique clinique et sa non-infériorité en termes d’efficacité est en cours d’évaluation. Des données pharmacologiques chez le volontaire sain et chez les patients confirment une concentration sanguine en morphine proche des concentrations efficaces observées en intraveineux (1 à 120 ng/ml dans CLIN-AEROMORPH), ce qui est déjà un résultat positif démontré par nos travaux. Par ailleurs, sur le plan de son éligibilité, nos données observationnelles et de simulation de décision, associées aux données médico-économiques que nous avons analysées dans la littérature, suggèrent la nécessité de baser son indication autrement que sur la simple évaluation par EVA/EN à l’accueil. Dans ce travail nous montrons que la pratique des praticiens témoigne aujourd’hui de leur manque d’adhésion au déclenchement systématique de la prescription d’opiacés Iv titrés par l’autoévaluation de la douleur sévère (de 6 à 20% de respect des critères SFMU, 61% de réinterprétation des scores EVA/EN). Si la titration aérosol est uniquement proposée en starter de la titration morphinique sans moderniser les algorithmes de décision de prescription opiacée dans les protocoles d’urgences, il est probable que cette nouvelle proposition thérapeutique ne résoudra qu’une partie de la problématique actuellement posée. Une prise en charge pharmacologique la plus individualisée possible est plus que jamais pertinente, avec une prescription ciblée de la titration morphinique selon la typologie du patient, en plus d’une priorisation par typologie douloureuse. En développant un « modèle douleur » original chez le volontaire sain, nous avons d’ailleurs mis en lumière des profils de patients « hyperesthésiques » et « endurants », sur le plan neurophysiologique et biochimique, qui sont sûrement retrouvés en pratique clinique quotidienne. L’ensemble de ces éléments doivent donc être pris en compte pour améliorer la prise en charge de la douleur en médecine d’urgence, avec une vision plus systémique, et davantage d’études dédiées, utilisant des méthodes d’évaluation innovantes mêlant critères quantitatifs robustes et qualitatifs exhaustifs.Our goal was to optimize the management of severe acute pain in emergency medicine. Intravenous morphine titration, which is currently the referent method, must be modernised to meet the new challenges of practice while at the same time, we must keep guaranteeing an unchanged risk-benefit balance in the fight against oligoanalgesia. Our work, described in this thesis, has been a cornerstone for the evaluation of a nebulized alternative solution to emergencies through 3 clinical studies, (AEROMORPH1, CLIN-AEROMORPH, EPIMORPH), and study of its contextualisation in literature. Work in healthy volunteers allowed us to establish a simple and accessible procedure for aerosol, of short duration (5 min), which can be repeated in titration procedures (every 10 min). Its feasibility is likely to be confirmed on our multicentre clinical study at a large scale and its efficacy, by a non-inferiority design of study is being evaluated. Pharmacological data in healthy volunteers and in patients confirm a blood morphine concentration close to the effective blood concentrations observed by intravenous administration (CLIN-AEROMORPH: 1-20 ng/ml), which is already a positive result demonstrated by our work. Moreover, regarding eligibility, our observational study, combined to a experiment about decision mechanisms, combined with the analysis of medico-economic data in literature, suggest the need to base its indication on more than just the simple VAS/NRS assessment at triage. In this work we showed that emergency practitioners’ practice today underlines their lack of adherence to the systematic initiation of intravenous morphine titration by patient self-assessment of severe pain (compliance with SFMU criteria 6 to 20%, re-assessment of VAS/NRS scores 61%). If nebulized morphine titration is only proposed as a starter for morphine titration without modernising the algorithms for opiate prescription decision in emergency protocols, it is likely that this new therapeutic proposal will only solve part of the current problem. Targeted pharmacological management, as individualised as possible, is more relevant than ever, with prescription of morphine titration according to the patient's typology, in addition to prioritisation by pain typology. By developing an original pain model in healthy volunteers, we have also highlighted profiles of "pain sensitive" and "enduring" patients, according to neurophysiological and biochemical data, that are certainly represented in daily clinical practice. Therefore, all these components should be taken into account to improve pain management in emergency medicine, with a more systemic vision and more dedicated studies using innovative evaluation methods, combining robust quantitative criteria with comprehensive qualitative criteria

Medico-economic study of pain in an emergency department: a targeted literature review

International audienceBackground: Pain management in emergency departments is a complex objective. The absence of a care pathway or a high level of activity complicates diagnostic or analgesic therapeutic strategies. Medical innovation can impact both individual practices and the functioning of an emergency department.Objective: We then wanted to understand how medico-economic studies on pain were carried out in an emergency department.Study design: We reviewed the literature of the last 20 years (between 1998 and 2018).Setting: Of 846 titles screened, a total of 268 abstracts qualified for further screening, and 578 titles were excluded. A total of 14 studies qualified for inclusion in the review. Studies on medico-economics in an emergency department are very diverse. None of the methods used are identical; the studies differ in their very nature (prospective, retrospective, cost-effectiveness, etc.) and the determination of emergency room costs differs according to the part of the world studied. In addition, organizational impact is rarely measured, although it is an essential dimension for choosing or not a medical innovation

Bedside Evaluation of Early VAS/NRS Based Protocols for Intravenous Morphine in the Emergency Department: Reasons for Poor Follow-Up and Targeted Practices

International audienceIntravenous (IV) morphine protocols based on patient-reported scores, immediately at triage, are recommended for severe pain in Emergency Departments. However, a low follow-up is observed. Scarce data are available regarding bedside organization and pain etiologies to explain this phenomenon. The objective was the real-time observation of motivations and operational barriers leading to morphine avoidance. In a single French hospital, 164 adults with severe pain at triage were included in a cross-sectional study of the prevalence of IV morphine titration; caregivers were interviewed by real-time questionnaires on “real” reasons for protocol avoidance or failure. IV morphine prevalence was 6.1%, prescription avoidance was mainly linked to “Pain reassessment” (61.0%) and/or “alternative treatment prioritization” (49.3%). To further evaluate the organizational impact on prescription decisions, a parallel assessment of “simulated” prescription conditions was simultaneously performed for 98/164 patients; there were 18 titration decisions (18.3%). Treatment prioritization was a decision driver in the same proportion, while non-eligibility for morphine was more frequently cited (40.6% p = 0.001), with higher concerns about pain etiologies. Anticipation of organizational constraints cannot be excluded. In conclusion, IV morphine prescription is rarely based on first pain scores. Triage assessment is used for screening by bedside physicians, who prefer targeted practices to automatic protocols

Relevance of early management by proton-pump inhibitor in acute upper gastro-intestinal tract disorder: A scoping review

Background: Proton-pump inhibitors (PPI) are frequently used in the emergency and general practice settings in several clinical presentations linked to acute upper gastro-intestinal tract disorders as abdominal or chest pain without recommendations. Objective: The aim of this scoping review was to assess pain reduction, diagnostic performance, and safety in the first 24 h-management in primary care or emergency medicine. Methods: Search was realized by 2 independent reviewers in PubMed, Embase, and Web of Science following PRISMA-ScR guidelines. Only original articles or systematic reviews in English were included. Studies about chronic and/or bleeding conditions, therapeutic cocktails and studies without pain evaluation were excluded. Two methodologies were used for bias estimation. Results: From 4442 titles, 79 full-text articles were assessed, and 9 were included. There is no strong evidence supporting the use of PPI as a first line analgesic or diagnostic test in acute syndromes linked to acute upper gastro-intestinal tract disorder. A small effect in pain reduction was retrieved in patients with low pain scores. A poor additional value in patients with gastric reflux, and a low specificity compared to other diagnostic tests were observed. A short-term PPI administration appears to be safe with low risk of serious allergic reactions, and poor adverse effects (moderate evidence). Conclusion: Although PPIs may contribute to the multimodal analgesia in acute settings, with few and/or minor side effects, no recommendation can be drawn for their use as a primary analgesic. Data regarding the relevance of the PPI test are much less clear, no data regarding care pathways are available

Relevance of cortisol and copeptin blood concentration changes in an experimental pain model

International audienceAbstract The effect of pain and analgesics on stress biomarkers is not well studied. We evaluated the effect of acute pain and analgesics on serum cortisol and copeptin in an experimental pain model in healthy volunteers. Healthy volunteers presented at 8 a.m. for an experimental pain stimulation. Cortisol and copeptin levels were measured before, during and after electrophysiological stimulation, first before and then during opioid delivery. Difference in biomarker levels compared to baseline levels was calculated, and potential influencing factors were evaluated by linear regression analysis. Cortisol decreased by 13% during the 10 min of rest at baseline, but copeptin did not change significantly. Cortisol had a median decrease of −24% or −83 nmol/l (−44 to −124 nmol/l, p = 0.0002) during the electrophysiological stimulation training session, while the median difference for copeptin was −22% or −1.01 pmol/l (−2.35 to 0.08 pmol/l, p = 0.0003). After administration of opioids, cortisol did not decrease but increased by 3% (p = 0.043), indicating an increasing opioids effect on cortisol. This effect was not visible for copeptin (median change −0.003 pmol/l (−0.50 to 0.24), p = 0.45). In this experimental pain model performed in the morning, moderate pain did not have a relevant effect on cortisol or copeptin levels, whereas opioids led to a discrete peak of cortisol.
