Caries prevalence in children from Valencia (Spain) using ICDAS II criteria, 2010
2014
Objectives: To assess the oral health status of the child population and its evolution over the 2004-2010 period. Study Design: A descriptive cross-sectional study of the entire schoolchild population of the Valencia region of Spain was conducted using cluster sampling. Seventy schools were selected. The sample size was 1373 pupils, aged 6, 12 and 15 years. The children were examined in November and December 2010, at their schools, by 6 examiners calibrated in the ICDAS II method. The descriptive statistics, comparison of means and comparison of proportions (p0) was 30% in primary dentition at 6 years and 37.7% and 43.6% in permanent dentition at 12 and 15 years respectively. At 6, 12 and 1…
Factors associated with epiphora following orbital‐sparing maxillectomy via modified Weber–Ferguson incision with lower blepharoplasty
2021
Purpose The aims of the study were to estimate the frequency of epiphora and to identify factors associated with epiphora after orbital-sparing maxillectomy via modified Weber-Ferguson incision with lower blepharoplasty (OSOSM-MWFILB). Methods We performed a retrospective cohort study enrolling a sample derived from the patient population undergoing OSM-MWFILB over a 7-year period. The predictor variables were grouped into demographic, related health status, anatomic, tumor-specific, and therapeutic categories. The primary outcome variable was the presence of postmaxillectomy epiphora (PME). Descriptive, univariate, and multivariate regression mixed-effect models were computed. Results The …
Long-term Leisure-time Physical Activity and Serum Metabolome
2013
Background— Long-term physical inactivity seems to cause many health problems. We studied whether persistent physical activity compared with inactivity has a global effect on serum metabolome toward reduced cardiometabolic disease risk. Methods and Results— Sixteen same-sex twin pairs (mean age, 60 years) were selected from a cohort of twin pairs on the basis of their >30-year discordance for physical activity. Persistently (≥5 years) active and inactive groups in 3 population-based cohorts (mean ages, 31–52 years) were also studied (1037 age- and sex-matched pairs). Serum metabolome was quantified by nuclear magnetic resonance spectroscopy. We used permutation analysis to estimate the …
Dynamic image denoising for voxel-wise quantification with Statistical Parametric Mapping in molecular neuroimaging.
2018
Purpose PET and SPECT voxel kinetics are highly noised. To our knowledge, no study has determined the effect of denoising on the ability to detect differences in binding at the voxel level using Statistical Parametric Mapping (SPM). Methods In the present study, groups of subject-images with a 10%- and 20%- difference in binding of [123I]iomazenil (IMZ) were simulated. They were denoised with Factor Analysis (FA). Parametric images of binding potential (BPND) were produced with the simplified reference tissue model (SRTM) and the Logan non-invasive graphical analysis (LNIGA) and analyzed using SPM to detect group differences. FA was also applied to [123I]IMZ and [11C]flumazenil (FMZ) clinic…
Awareness on oral cancer among patients attending dental school clinics in Brazil
2019
Background Oral cancer is considered a public health problem worldwide. Dental schools may play an important role in educating patients about oral cancer. This study aimed at evaluating the knowledge of patients attending clinics at two dental schools in Brazil. Material and Methods From March 2017 to April 2017, 251 patients who were attending clinics at two dental schools in Recife, Brazil, were included in the study. Patients were contacted in the waiting rooms of the clinic. Each participant completed a self-administered questionnaire, which consists of 21 questions, including socio-demographic and specific information on the disease. Data were analyzed using descriptive statistics, and…
Human voice pitch measures are robust across a variety of speech recordings: methodological and theoretical implications
2021
Fundamental frequency ( f o ), perceived as voice pitch, is the most sexually dimorphic, perceptually salient and intensively studied voice parameter in human nonverbal communication. Thousands of studies have linked human f o to biological and social speaker traits and life outcomes, from reproductive to economic. Critically, researchers have used myriad speech stimuli to measure f o and infer its functional relevance, from individual vowels to longer bouts of spontaneous speech. Here, we acoustically analysed f o in nearly 1000 affectively neutral speech utterances (vowels, words, counting, greetings, read paragraphs and free spontaneous speech) produced by the same 154 men and women, ag…
The Prevalence of Sexual Violence: Results From a Population-Based Sample
2016
BACKGROUND: Sexual violence can cause severe mental and bodily harm. This is the first study of a population-based sample in Germany to assess both the frequency of the subjects' having experienced sexual violence and the frequency of their having manifested sexually aggressive behavior themselves. METHODS: 2513 persons (of whom 2422 were over age 18 and 91 were aged 14 to 18) were asked about their experiences with sexual violence in the past 12 months, either as the person committing sexual violence or as the victim of sexual violence at the hands of other adults or similarly aged adolescents. RESULTS: 0.6% (n = 6) of the men and 1.2% (n = 16) of the women surveyed, and ca. 5% (n = 4) of …
On the limits of familiarity accounts in lexical decision: The case of repetition effects
2019
Recent modelling accounts of the lexical decision task have suggested that the reading system performs evidence accumulation to carry out some functions. Evidence accumulation models have been very successful in accounting for effects in the lexical decision task, including the dissociation of repetition effects for words and nonwords (facilitative for words but inhibitory for nonwords). The familiarity of a repeated item triggers its recognition, which facilitates ‘word’ responses but hampers nonword rejection. However, reports of facilitative repetition effects for nonwords with several repetitions in short blocks challenge this hypothesis and favour models based on episodic retrieval. T…
Attitude and knowledge of pain management among Italian nurses in hospital settings
2015
Pain is multidimensional, and, as such, the chief reason patients seek urgent healthcare services. If inadequately assessed and untreated, pain may negatively impact on the quality of life of the patient. Treating pain is an important step in regaining control over quality of life. The objective of the present study is to examine the level of knowledge and types of approach among Italian nurses who deal with pain assessment and management. The Ferrell and McCaffery's Knowledge and Attitudes Survey Regarding Pain (KASRP) was distributed to 286 nurses employed in one of the biggest specialized hospitals in Rome, Italy. The interviewed staff work at three different settings, according to the h…
Access to Healthcare for Migrant Patients in Europe: Healthcare Discrimination and Translation Services
2021
Background: Discrimination based on ethnicity and the lack of translation services in healthcare have been identified as main barriers to healthcare access. However, the actual experiences of migrant patients in Europe are rarely present in the literature. Objectives: The aim of this study was to assess healthcare discrimination as perceived by migrants themselves and the availability of translation services in the healthcare systems of Europe. Methods: A total of 1407 migrants in 10 European Union countries (consortium members of the Mig-HealthCare project) were surveyed concerning healthcare discrimination, access to healthcare services, and need of translation services using an interview…
