Sinus floor elevation with platelet-rich fibrin alone : a clinical retrospective study of 1-7 years
2018
Background Several sinus floor elevation procedures for implant placement have been introduced. The present study aimed to evaluate the implants placed with Platelet-rich fibrin (PRF) alone in atrophic posterior maxillae and survival rates and the potential factors associated with implant loss. Material and Methods This retrospective study evaluated 71 implants in 34 patients after 1-7 years' follow-up time. Statistical models were used to determine the implant survival and the potential factors associated with loss. Results Overall, 7 implants were lost, and the cumulative survival rate at 7 years by implant-based and patient-bases analyses were 85.5% and 85.7%, respectively. The mean resi…
Clinical retrospective study of dental implant removal : do patients who require implant removal desire implant prosthesis again?
2020
Background This study investigated the causes of dental implant removal due to complications, and examined whether patients who had dental implant removal desired re-implant prosthesis treatments. Material and Methods A retrospective case–control study was conducted on patients who had their dental implants removed. We investigated whether the removed dental implant was replaced with other implant prostheses. Age, sex, diabetes, smoking, implant site distribution, reason for implant removal, and blade and root-form implants were categorized as predictive variables. The outcome variable was desire for re-implantation or use of other prosthetic methods after implant removal. A logistic regres…

Post-orthodontic position of lower incisors and gingival recession: A retrospective study
2017
Background To evaluate if changes in lower incisor position following orthodontic treatment are correlated with development of gingival recessions. Material and methods Pre- and post-treatment digital models and lateral cephalograms of 22 subjects were collected retrospectively. The clinical crown length, gingival scallop, and papilla height of the central lower incisor were measured along with the cephalometric incisor's inclination, the distance from the mandibular plane, and the distance between the Infradentale and Menton points. Statistical correlations between gingival and cephalometric variables were studied. In addition, two groups were defined based on the post-treatment incisor in…
Is COVID‐19 infection more severe in kidney transplant recipients?
2021
International audience; There are no studies which have compared the risk of severe Covid-19 and related mortality between transplant recipients and non-transplant patients. We enrolled two groups of patients hospitalized for Covid-19, i.e., kidney transplant recipients from the French Registry of Solid Organ Transplant (n=306) and a single-center cohort of non-transplant patients (n=795). An analysis was performed among subgroups matched for age and risk factors for severe Covid-19 or mortality. Severe Covid-19 was defined as admission (or transfer) to an intensive care unit, need for mechanical ventilation, or death.Transplant recipients were younger and had more comorbidities compared to…
Reproducibility and validity of a food frequency questionnaire among pregnant women in a Mediterranean area
2013
Background: Studies exploring the role of diet during pregnancy are still scarce, in part due to the complexity of measuring diet and to the lack of valid instruments. The aim of this study was to examine the reproducibility and validity (against biochemical biomarkers) of a semi-quantitative food frequency questionnaire (FFQ) in pregnant women. Methods: Participants were 740 pregnant women from a population-based birth cohort study in Valencia (INMA Study). We compared nutrient and food intakes from FFQs estimated for two periods of pregnancy (reproducibility), and compared energy-adjusted intake of several carotenoids, folate, vitamin B12, vitamin C and a-tocopherol of the FFQ in the firs…
Efectos del Binge Drinking sobre variables fisiológicas y cognitivas (memoria visual inmediata y memoria de trabajo) en adolescentes.
2016
El etanol es la droga dura legal más consumida en España. El uso y abuso de esta sustancia ocasiona múltiples consecuencias sociales y sanitarias por lo que se trata de uno de los problemas de salud pública más importantes tanto a nivel nacional como a nivel mundial. En muchos países, entre los que se encuentra España, el porcentaje de adolescentes que consumen alcohol es alarmante, con prevalencia de un nuevo patrón de consumo de alcohol al que coloquialmente se ha denominado “botellón” o Binge Drinking (BD) en inglés. Este patrón de consumo intensivo o en “atracón” de alcohol se caracteriza por la ingesta de grandes cantidades de alcohol de alta graduación en cortos espacios de tiempo (po…
Profiles of mental well- and ill-being among elite athletes: Associations with sport-related demands and resources
2022
The aim of the present study was to identify profiles of elite athlete mental well- and ill-being and study how the profiles (i.e., subgroups of athletes) differed in sport-related demands and resources. A total of 259 Finnish elite athletes (n = 170 active and n = 89 retired) completed quantitative self-report inventories. Through cluster analysis, four profiles of mental well- and ill-being were identified. Profile 1 was overrepresented by retired, older, and male athletes, and characterized by good mental well-being. Profile 2 consisted mainly of active athletes who reported mild risk for alcohol abuse. Profile 3 consisted mainly of women who displayed possible presence of an eating diso…
Physical activity reduces the risk of pneumonia : systematic review and meta-analysis of 10 prospective studies involving 1,044,492 participants
2022
The beneficial effects of regular physical activity in promoting health and preventing chronic diseases are well documented. The relationship between regular physical activity and the risk of pneumonia is uncertain. We aimed to evaluate the magnitude and specificity of the prospective association between regular physical activity and the risk of pneumonia using a systematic review and meta-analysis of published observational cohort studies in general populations. Relevant studies with at least 1 year of follow-up were sought from inception until 15 September 2021 in MEDLINE, Embase, Web of Science, and manual search of relevant articles. Relative risks (RRs) with 95% confidence intervals (C…
Amplicon-based high-throughput pooled sequencing identifies mutations in CYP7B1 and SPG7 in sporadic spastic paraplegia patients
2011
Hereditary spastic paraplegia (HSP) is a neurodegenerative disorder defined clinically by progressive lower limb spasticity and weakness. HSP is a genetically highly heterogeneous condition with at least 46 gene loci identified so far, involving X-linked, autosomal recessive (AR) and autosomal dominant inheritance. For correct diagnosis, molecular testing is essential because clinical parameters by themselves are not reliable to differentiate HSP forms. The purpose of this study was to establish amplicon-based high-throughput genotyping for AR-HSP. A sample of 187 index cases with apparently sporadic or recessive spastic paraplegia were analyzed by applying an array-based amplification stra…
