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

Severe pain management in the emergency department: patient pathway as a new factor associated with IV morphine prescription

BackgroundAcross the world, 25–29% of the population suffer from pain. Pain is the most frequent reason for an emergency department (ED) visit. This symptom is involved in approximately 70% of all ED visits. The effective management of acute pain with adequate analgesia remains a challenge, especially for severe pain. Intravenous (IV) morphine protocols are currently indicated. These protocols are based on patient-reported scores, most often after an immediate evaluation of pain intensity at triage. However, they are not systematically prescribed. This aspect could be explained by the fact that physicians individualize opioid pain management for each patient and each care pathway to determine the best benefit–risk balance. Few data are available regarding bedside organizational factors involved in this phenomenon.ObjectiveThis study aimed to analyze the organizational factors associated with no IV morphine prescription in a standardized context of opioid management in a tertiary-care ED.MethodsA 3-month prospective study with a case–control design was conducted in a French university hospital ED. This study focused on factors associated with protocol avoidance despite a visual analog scale (VAS) ≥60 or a numeric rating scale (NRS) ≥6 at triage. Pain components, physician characteristics, patient epidemiologic characteristics, and care pathways were considered. Qualitative variables (percentages) were compared using Fisher’s exact test or the chi-squared tests. Student’s t-test was used to compare continuous variables. The results were expressed as means with their standard deviation (SD). Factors associated with morphine avoidance were identified by logistic regression.ResultsA total of 204 patients were included in this study. A total of 46 cases (IV morphine) and 158 controls (IV morphine avoidance) were compared (3:1 ratio). Pain patterns and patient’s epidemiologic characteristics were not associated with an IV morphine prescription. Regarding NRS intervals, the results suggest a practice disconnected from the patient’s initial self-report. IV morphine avoidance was significantly associated with care pathways. A significant difference between the IV morphine group and the IV morphine avoidance group was observed for “self-referral” [adjusted odds ratio (aOR): 5.11, 95% CIs: 2.32–12.18, p < 0.0001] and patients’ trajectories (Fisher’s exact test; p < 0.0001), suggesting IV morphine avoidance in ambulatory pathways. In addition, “junior physician grade” was associated with IV morphine avoidance (aOR: 2.35, 95% CIs: 1.09–5.25, p = 0.03), but physician gender was not.ConclusionThis bedside case–control study highlights that IV morphine avoidance in the ED could be associated with ambulatory pathways. It confirms the decreased choice of “NRS-only” IV morphine protocols for all patients, including non-trauma patterns. Modern pain education should propose new tools for pain evaluation that integrate the heterogeneity of ED pathways

Cytokine Profiles in Sepsis Have Limited Relevance for Stratifying Patients in the Emergency Department: A Prospective Observational Study

INTRODUCTION: Morbidity, mortality and social cost of sepsis are high. Previous studies have suggested that individual cytokines levels could be used as sepsis markers. Therefore, we assessed whether the multiplex technology could identify useful cytokine profiles in Emergency Department (ED) patients. METHODS: ED patients were included in a single tertiary-care center prospective study. Eligible patients were >18 years and met at least one of the following criteria: fever, suspected systemic infection, ≥ 2 systemic inflammatory response syndrome (SIRS) criteria, hypotension or shock. Multiplex cytokine measurements were performed on serum samples collected at inclusion. Associations between cytokine levels and sepsis were assessed using univariate and multivariate logistic regressions, principal component analysis (PCA) and agglomerative hierarchical clustering (AHC). RESULTS: Among the 126 patients (71 men, 55 women; median age: 54 years [19-96 years]) included, 102 had SIRS (81%), 55 (44%) had severe sepsis and 10 (8%) had septic shock. Univariate analysis revealed weak associations between cytokine levels and sepsis. Multivariate analysis revealed independent association between sIL-2R (p = 0.01) and severe sepsis, as well as between sIL-2R (p = 0.04), IL-1β (p = 0.046), IL-8 (p = 0.02) and septic shock. However, neither PCA nor AHC distinguished profiles characteristic of sepsis. CONCLUSIONS: Previous non-multiparametric studies might have reached inappropriate conclusions. Indeed, well-defined clinical conditions do not translate into particular cytokine profiles. Additional and larger trials are now required to validate the limited interest of expensive multiplex cytokine profiling for staging septic patients

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
