Effects of preemptive analgesia with intravenous acetaminophen on postoperative pain relief in patients undergoing third molar surgery: a prospective…
2020
Background The efficacy of preemptive analgesia in managing postoperative pain remains controversial. The aim of this study was to compare the efficacy of intravenous (IV) acetaminophen administered before or immediately after the surgical extraction of an impacted mandibular third molar. Material and Methods This prospective randomized clinical trial included 120 patients. The patients were assigned to one of three groups: the preoperative-treatment group (pre-group), which received 1000 mg of IV acetaminophen 20 min before surgery; the postoperative-treatment group (post-group), which received 1000 mg of IV acetaminophen after surgery; the no-treatment group (control-group), which did not…
Ascorbic acid reduces noise-induced nitric oxide production in the guinea pig ear.
2008
Objectives: Noise-induced hearing loss can be caused, among other causes, by increased nitric oxide (NO) production in the inner ear leading to nitroactive stress and cell destruction. Some studies in the literature suggest that the degree of hearing loss (HL) could be reduced in an animal model through ascorbic acid supplementation. To identify the effect of ascorbic acid on tissue-dependent NO content in the inner ear of the guinea pig, we determined the local NO production in the organ of Corti and the lateral wall separately 6 hours after noise exposure. Study Design: Prospective animal study in guinea pigs. Methods: Over a period of 7 days, male guinea pigs were supplied with minimum (…
Non-surgical periodontal treatment with a new ultrasonic device (Vectortm-ultrasonic system) or hand instruments. A prospective, controlled clinical …
2004
Objectives: The aim of this prospective, randomized, controlled clinical study was to compare the effectiveness of a newly developed ultrasonic device to that of scaling and root planing for non-surgical periodontal treatment. Material and Methods: Thirty-eight patients with moderate to advanced chronic periodontal disease were treated according to an “one-stage procedure” with either a newly developed ultrasonic device (VUS) (Vector™-ultrasonic system) or scaling and root planing (SRP) using hand instruments. Clinical assessments by plaque index (PlI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), gingival recession (GR), and clinical attachment level (CAL) were made …
Change and stability: Within-person life satisfaction over a 20-year period using data from the HUNT survey
2020
Background: The aim of the present study was to investigate within-person life satisfaction (LS) dynamics for two age groups, 20–29 and 30–39 years, from 1984 to 1986 and to follow them over a 20-year period. Methods: Data from 1984 to 2008 were extracted from the large, prospective, longitudinal North-Trøndelag Health Study (HUNT), Norway. This paper includes data from more than 14,500 persons. Data were analysed using logistic regression, and LS dynamics were modelled using gender, time and self-rated health. Results: The analyses revealed that about 20% of people in these age groups had a stable level in LS, also known as set point. Long-term LS change, defined as ⩾2 SDs, was reported f…
Parental and Familial Factors Influencing Physical Activity Levels in Early Adolescence: A Prospective Study
2020
Parental/familial factors are important determinants of the physical activity level (PAL) in children and adolescents, but studies rarely prospectively evaluate their relationships. This study aimed to evaluate the changes in physical activity levels among adolescents from Bosnia and Herzegovina over a two-year period and to determine parental/familial predictors of PAL in early adolescence. A total of 651 participants (50.3% females) were tested at baseline (beginning of high school education
Territoires urbains en transition. Monographie d’un quartier populaire en résilience écologique, Editions Universitaires de Dijon, décembre 2015
2015
National audience; Que faites-vous pour la planète? Vous prenez le vélo pour aller travailler? Vous recyclez des tissus pour fabriquer et peut-être vendre des vêtements? Vous avez choisi une pratique sportive durable dans un club près de chez vous? Vous mangez bio? Vous utilisez les réseaux sociaux pour faire connaître vos éco-gestes à vos voisins ou à l'autre bout du monde? Imaginez... A quoi pourrait ressembler un quartier populaire en 2050, si on ne fait rien pour protéger l’environnement ou, à l'inverse, si on fait tout pour le préserver?Une équipe pluridisciplinaire a enquêté durant deux ans, entre 2012 et 2014, auprès de la population d'un de ces quartiers, la Fontaine d'Ouche, en pro…
An ABM to support collective reflection on the evolution of mobility
2021
International audience; Transport infrastructures play a large part in defining a smart, sustainable and resilient city. Planning transportation systems traditionally rely on well-known evolutions of roads or public transportation (roundabouts for security, etc.). Yet, infrastructures might also benefit from, or may have to adapt to, recent disruptive innovations concerning modalities, technologies and societal organization (autonomous cars, smart infrastructure, homeworking, etc.). However, innovative urban policies might either facilitate mobility and increase citizen well-being, or create negative side effects. Urban planning therefore requires the city to assess the impact of these disr…
Ex Ante evaluation of gene flow in oilseed rape with cropping system models
2013
Chapitre 4; Oilseed rape (OSR) genes can escape fields in space via pollen and seeds, and in time via volunteers resulting from seeds lost before or during oilseed rape harvest. When varieties co-exist, e.g. genetically-modified (GM) and non-GM varieties, this spatio-temporal gene flow can lead to the adventitious presence of GM seeds in non-GM harvests and thus cause financial losses for farmers and cooperatives. Gene flow depends on crop locations, succession, and management, as well as the location and management of semi-natural areas such as roadverges. The objective of this investigation was to present a simulation methodology using the spatially-explicit cropping system model GENESYS …
Décroître pour rebondir : le déclassement des villes moyennes, une opportunité pour repenser la ville
2019
International audience; La politique contemporaine d’aménagement du territoire en France comme dans de nombreux pays favorise l’affirmation des grandes entités urbaines. Sous l’impulsion de la mondialisation de l’économie, la concentration des moyens humains et matériels dans un nombre réduit de très grandes agglomérations a largement contribué à reléguer les villes moyennes dans l’ombre des métropoles. Les centres de ces villes moyennes sont eux-mêmes concurrencés par leur périphérie à dominante rurale qui offre des opportunités de logement individuel plus avantageuses pour les ménages. Appréhendée de manière conjoncturelle, cette situation conduit à qualifier nombre de villes moyennes com…
