Current trends in orthodontic journals listed in Journal Citation Reports. A bibliometric study.

2018

Introduction The aim of this study is to analyze articles published in orthodontic journals included in Journal Citation Reports (JCR) to determine current trends in orthodontic publishing. Methods Articles included in orthodontic journals in 2016 JCR and published during 2007-2017 were selected. After applying inclusion criteria, author-based parameters (article title, first author's name, institution and sex, number of authors, number of affiliations, first author's origin, and geographic origin), article-based parameters (article type, main topic, and research design), and the number of cites and self-cites were registered for each article. Results A total of 7119 articles were analyzed,…

2021

An observational cross-sectional survey was planned to analyze the weekly workload reduction of German dentists during lockdown due to the global COVID-19 pandemic. Participants were predominantly members of the Free Association of German Dentists and filled in an online questionnaire. The questionnaire was sent to a total of 9416 dentists, with a response rate of 27.98% (n = 2635). Respondents were divided into seven macro areas by gross domestic product. Nearly two-thirds of dentists (65.16%) reported a reduction in their practice workload of more than 50% compared to the pre-pandemic period with statistically significant differences between German macro areas (p < 0.01). Weekly worklo…

Knowledge about COVID-19 and pandemic impact on Madrid dental students (Spain).

2020

Background: COVID-19 has had a major impact on dental activity, with implications on dental education. The aim of this study was to assess the knowledge about it and the pandemic impact on Spanish dental students. Material and Methods: An observational and cross-sectional study with a 17-items questionnaire was conducted. It was divided into three sections, sociodemographic data, self-perception and knowledge about the COVID-19 protective measures and repercussions on dental students. This survey was carried out in May 2020, and the response rate was 46.16%. The statistical analysis was performed by the Pearson chi-square test and Fisher’s exact test. Results: A total of 235 students respon…

Peripheral Frequency of CD4+ CD28- Cells in Acute Ischemic Stroke: Relationship With Stroke Subtype and Severity Markers.

2015

CD4+ CD28− T cells also called CD28 null cells have been reported as increased in the clinical setting of acute coronary syndrome. Only 2 studies previously analyzed peripheral frequency of CD28 null cells in subjects with acute ischemic stroke but, to our knowledge, peripheral frequency of CD28 null cells in each TOAST subtype of ischemic stroke has never been evaluated. We hypothesized that CD4+ cells and, in particular, the CD28 null cell subset could show a different degree of peripheral percentage in subjects with acute ischemic stroke in relation to clinical subtype and severity of ischemic stroke. The aim of our study was to analyze peripheral frequency of CD28 null cells in subjects…

Risk perception and knowledge of COVID-19 in patients with celiac disease

2021

BACKGROUND We recently demonstrated that the odds of contracting coronavirus disease 2019 (COVID-19) in patients with celiac disease (CeD) is similar to that of the general population. However, how patients with CeD perceive their COVID-19 risk may differ from their actual risk. AIM To investigate risk perceptions of contracting COVID-19 in patients with CeD and determine the factors that may influence their perception. METHODS We distributed a survey throughout 10 countries between March and June 2020 and collected data on demographics, diet, COVID-19 testing, and risk perceptions of COVID-19 in patients with CeD. Participants were recruited through various celiac associations, clinic visi…

Aspirin use and breast cancer risk: a meta-analysis and meta-regression of observational studies from 2001 to 2005

2007

Purpose To examine the recent epidemiological studies on aspirin use and breast cancer risk published from 2001 to 2005 within a meta-analysis, to investigate reasons for heterogeneity between the individual studies and to analyse a dose-response-relationship considering frequency and duration of use. Methods We systematically searched for cohort-studies and case-control-studies from 2001–2005, which evaluated the association between aspirin and breast cancer risk. We calculated a pooled estimate for the relative risk (RR) and investigated reasons for heterogeneity between the individual studies and analysed a dose-response-relationship using random effects mixed models. Results We identifi…

Commonalities and distinctions between two neurodevelopmental disorder subtypes associated with SCN2A and SCN8A variants and literature review.

2022

This study was aimed to analyze the commonalities and distinctions of voltage-gated sodium channels, Nav1.2, Nav1.6, in neurodevelopmental disorders. An observational study was performed including two patients with neurodevelopmental disorders. The demographic, electroclinical, genetic, and neuropsychological characteristics were analyzed and compared with each other and then with the subjects carrying the same genetic variants reported in the literature. The clinical features of one of them argued for autism spectrum disorder and developmental delay, the other for intellectual disability, diagnoses confirmed by the neuropsychological assessment. The first patient was a carrier of SCN2A (p.…

Predictors of scaffold failure and impact of optimized scaffold implantation technique on outcome: Results from the German-Austrian ABSORB RegIstRy.

2021

Aims We aimed to investigate predictors of scaffold failure and the potential impact of an optimized scaffold implantation technique by means of a learning curve on long-term clinical outcome after bioresorbable scaffold (BRS) implantation and to evaluate predictors of scaffold failure. Methods and results A total of 3326 patients were included in this prospective, observational, multi-center study (ClinicalTrials.gov NCT02066623) of consecutive patients undergoing BRS implantation between November 2013 and January 2016. The 3144 patients completed follow-up after 24 months, 3265 patients were eligible for time-to-event-analysis. Clinical endpoints were major adverse cardiac events-a compos…

Mortality associated with the use of inappropiate drugs according Beers Criteria: a systematic review

2013

The aims of this systematic review are to identify and analyse the scientist literature available evidence about the use of potentially inappropriate medications, according to the Beers Criteria, that is associated with mortality in the elderly people.It have been made a search of publications in most traditional electronic databases among the scientific community (Pubmed / Medline, EMBASE and Web of Science) and it have been selected publications that obey the criteria of 'observational study', 'elderly' and 'Beers Criteria' and that they had as a result the mortality of the study population. After publications selection it proceeded to dump data by two researchers independently to avoid s…

Necesidad de una coordinación socio-sanitaria ante situaciones de emergencia social en las localidades de Xàtiva y Ontinyent (España)

2019

This article try to show up whether there is a need to coordinate the local Social Services (“SS.SS” in Spanish) with the Emergency Health Care Service (“SAMU” in Spanish) from both Xàtiva and Ontinyent (towns of the Community of Valencia) in order to allow an integrated care, carried out using an ad-hoc survey completed by (“SAMU” in Spanish) health workers and social workers from both Xàtiva and Ontinyent making up a descriptive, cross-sectional and observational study. Some of the results show that all the professionals point out the absolute need to coordinate the SAMU with the (“SS.SS” in Spanish) and that almost all of the sample believe that it is essential or necessary to implement …
