NfL predicts relapse-free progression in a longitudinal multiple sclerosis cohort study
2021
Background: Easily accessible biomarkers enabling the identification of those patients with multiple sclerosis (MS) who will accumulate irreversible disability in the long term are essential to guide early therapeutic decisions. We here examine the utility of serum neurofilament light chain (sNfL) for forecasting relapse-free disability progression and conversion to secondary progressive MS (SPMS) in the prospective Neurofilament and longterm outcome in MS (NaloMS) cohort. Methods: The predictive ability of sNfL at Baseline and sNfL follow-up (FU)/ Baseline (BL) ratio with regard to disability progression was assessed within a development cohort (NaloMS, n=196 patients with relapsing-remitt…
Determinants of dental care utilization by the adult population in Buenos Aires
2008
Objective: To establish the frequency with which the general population is seen by a dentist and the variables associated with the lack of regular dental check-ups. Methods: A cross-sectional study with a descriptive and analytical phase conducted in an urban community in Argentina. A sample population was obtained by stratified method. Socioeconomic conditions (measure by UBN index), health, health coverage, level of education and location of the households with respect to the dental clinics were all taken into consideration in selecting the sample. We performed a uni-and multivariate analysis. The statistical software used was SPSS 9.0 for Windows and Epilnfo6 Version 6.0. Results: We obs…
Application of an oral health-related quality of life questionnaire in primary care patients with orofacial pain and temporomandibular disorders
2013
Objectives: To examine whether patients who report orofacial pain (OP) and temporomandibular disorders (TMD) have a poorer perception of their oral health-related quality of life and, if so, to what extent, and to analyze the association between oral health perception, sociodemographic variables and reported pain duration. Study Design: 407 patients treated at the OP and TMD units in the Healthcare District of Cordoba, Spain, diagnosed following the standard criteria accepted by the scientific community – the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) – were administered the Spanish version of the Oral Health Impact Profile questionnaire (OHIP-14). Bivariate and …
Gender differences in variables associated with sleep quality in chronic tension type headache
2018
We aimed to evaluate gender differences in the relationships between headache features, sleep quality, anxiety, depressive symptoms, and burden of headache in 193 patients (73 percent women) with chronic tension type headache (CTTH). Sleep quality was assessed with the Pittsburgh Sleep Quality Index. Headache features were collected with a four-week diary. The Hospital Anxiety and Depression Scale was used to assess anxiety/depressive symptoms. Headache Disability Inventory was used to evaluate the burden of headache. In men with CTTH, sleep quality was positive correlated with headache frequency (r = 0.310; p = .018), emotional (r = 0.518; p < .001) and physical (r = 0.468; p < .001) burde…
The association between time scarcity, sociodemographic correlates and consumption of ultra-processed foods among parents in Norway: a cross-sectiona…
2017
Background Use of ultra-processed foods has expanded rapidly over the last decades and high consumption has been positively associated with risk of e.g. overweight, obesity and type 2 diabetes. Ultra-processed foods offer convenience as they require minimal time for preparation. It is therefore reasonable to assume that such foods are consumed more often among people who experience time scarcity. The main aim of this study was to investigate the association between time scarcity and consumption of ultra-processed foods among parents of 2-year olds in Norway. A secondary aim was to investigate the association between sociodemographic correlates, weight status and consumption of ultra-process…
Childhood adaptation: Perception of the parenting style and the anxious‐depressive symptomatology
2020
Objectives Childhood adaptation is essential for proper social-emotional development. Children growing up in a family context where they feel supported and protected are less vulnerable in the presence of psychopathology. The aim of this study is analysing the impact of parenting styles and the anxious-depressive symptoms on child adaptation. Design and setting A total of 367 children between the ages of 10 and 12, following a similar distribution by sex. The children completed self-reports assessing parenting styles, child adaptation, and depressive-anxiety symptomatology. Methods The data were analysed using two complementary methodologies: linear regressions and fuzzy-set qualitative com…
Knowledge and attitudes towards the use of antibiotics in the paediatric age group: a multicenter survey in Italy
2017
Background : The misuse of antibiotics is one of the leading causes of antibiotic resistance. Paediatric patients are highly involved in this issue, as they are those who receive the largest amount of prescriptions of these drugs. Therefore, this study aimed to investigate the general knowledge regarding the use of antibiotics, as well as the attitudes related to the administration of these drugs to children, amongst parents of children in the paediatric age-group. Methods : In 2014, a multicentre cross-sectional study was conducted amongst parents of children aged 0–14. A questionnaire made up of 33 items was administered in waiting rooms of outpatient departments. Multivariable logistic r…
Effectiveness of Toki s criteria and determination of variables for identification of HPV L1 protein in oral lesions
2013
Objectives: To evaluate the effectiveness of Toki's criteria in identifying the HPV L1 protein in oral lesions with the use of immunohistochemistry (IHC) and to determine which criteria optimize such identification. Study Design: Retrospective study of 277 cases diagnosed as HPV lesions at 22 years. Tests of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), kappa coefficients, and chi 2 values, as well as two logistic regression analyses ( (p≤0.05), were conducted. Results: Of the lesions studied, 96.4% (267 of 277) were positive for HPV using Toki's criteria and 28.5% (79 of 277) were positive for L1 by IHC. Toki's criteria showed sensitivity=93.67…
The association between diabetes and cataract among 42,469 community-dwelling adults in six low- and middle-income countries
2018
Background: Cataract is a major cause of visual impairment in people with diabetes, yet a paucity of data is available in low- and middle-income countries (LMICs) on this comorbidity. Thus we assessed the association between diabetes and cataract in 6 LMICs. Methods: Cross-sectional, community-based data from the Study on Global Ageing and Adult Health (SAGE) was analyzed (n = 42,469 aged ≥18 years). Five years information on self-reported diagnosis of cataract was collected. Three definitions for cataract were used: (a) Self-reported diagnosis and/or past 12-month symptoms; (b) Solely self-reported diagnosis; and (c) Surgical treatment for cataract in the past five years. Diabetes was base…
A retrospective follow up study on maternal age and infant mortality in two Sicilian districts
2011
Abstract Background Infant mortality rate (IMR) is a key public health indicator. Maternal age is a well-known determinant of pregnancy and delivery complications and of infant morbidity and mortality. In Italy the Infant Mortality Rate was 3.7/1000 during 2005, lower than the average IMR for the European Union (4.94/1000). Sicily is the Italian region with the highest IMR, 5/1000, and neonatal mortality rate (NMR), 3.8/1000, with substantial variation among its nine districts. The present study compared a high IMR/NMR district (Messina) with a low IMR/NMR district (Palermo) during the period 2004-2006 to evaluate potential determinants of the IMRs' differences between the two districts and…
