Determinants of HIV outpatient service utilization according to HIV parameters
2014
Introduction : The increased life expectancy of HIV patients in the era of highly active antiretroviral therapy has had profound consequences for the healthcare systems that provide their care. It is useful to assess whether healthcare resources need to be adapted to the different stages of HIV infection or to patient characteristics [1]. To study how patient features influence utilization of out patient services, we retrospectively analyzed the electronic health record of HIV-positive patients who had followed day-care programs at the AIDS Center of the University of Palermo, Italy. Materials and Methods : 223 HIV-infected subjects were recruited and divided into two groups according to CD…
Analysis of the factors linked to a diagnosis of attention deficit hyperactivity disorder in children
2017
Introduction: Attention deficit hyperactivity disorder (ADHD) is a neuropsychiatric disorder originating from multiple factors. The aim of this study is to determine the percentage of patients with ADHD out of all patients referred to our clinic for assessment, and to explore the epidemiological and clinical factors linked to this diagnosis. Patients and methods: Retrospective analytical study of a sample of patients under 15 years old sent to the paediatric neurology clinic for suspected ADHD. DSM-IV criteria were used for diagnosis. We completed a binary logistic regression analysis to determine which risk factors were associated with the diagnosis. Results: Of the 280 selected patients, …

Understanding Primary Ciliary Dyskinesia: Experience From a Mediterranean Diagnostic Reference Centre
2020
Background: Due to the lack of a gold standard diagnostic test, reference centres with experienced personnel and costly procedures are needed for primary ciliary dyskinesia (PCD) diagnostics. Diagnostic flowcharts always start with clinical symptoms. Therefore, the aim of this work is to define differential clinical criteria so that only patients clinically compatible with PCD are referred to reference centres. Materials and methods: 18 variables from 476 Mediterranean patients with clinically suspicious PCD were collected. After analysing cilia function and ultrastructure, 89 individuals were diagnosed with PCD and 387 had a negative diagnosis. Simple logistic regression analysis, consider…
Association between playing tactics and creating scoring opportunities in elite football. A case study in Spanish Football National Team
2015
The aim of this study was to examine the association between playing tactics, situational variables and creating scoring opportunities according to the type of start-up possession in a case-study. All team possessions (n=857) developed by the Spanish Football national team during the World Cup 2010 were analysed and grouped into “strategic set-plays” (n=90), “recoveries” (n=451) and “restarts” (n=316). Fourteen categorical variables which describe offensive playing tactics, opponent situation as well as situational variables and their associations with creating scoring opportunities were examined using chi-square analysis and bivariate logistic regressions. Chi-square analysis showed that “…
An innovative way to highlight the power of each polymorphism on elite athletes phenotype expression
2017
The purpose of this study was to determine the probability of soccer players having the best genetic background that could increase performance, evaluating the polymorphism that are considered Performance Enhancing Polymorphism (PEPs) distributed on five genes: PPAR alpha, PPARGC1A, NRF2, ACE e CKMM. Particularly, we investigated how each polymorphism works directly or through another polymorphism to distinguish elite athletes from non-athletic population. Sixty professional soccer players (age 22.5 +/- 2.2) and sixty healthy volunteers (age 21.2 +/- 2.3) were enrolled. Samples of venous blood was used to prepare genomic DNA. The polymorphic sites were scanned using PCR-RFLP protocols with …
Assessment of Periodontal status in Patients with Psoriatic Arthritis : a retrospective, case-control study
2021
Background Psoriatic arthritis (PsA) and periodontitis both represent chronic inflammatory disorders that share similar pathophysiological processes. However, very few studies have been done to address the link between the two diseases which remains poorly understood. The present study aimed to assess and compare the periodontal status in patients suffering from PsA and systemically healthy subjects to identify whether a possible association exists between PsA and periodontitis. Material and Methods Periodontal parameters – PI, BOP, mGI, PPD and CAL were recorded in 110 patients with PsA and 110 age- and gender-matched systemically healthy patients. Mean values of the periodontal parameters…
Predicting First-Year College Student Retention: Validation of the College Persistence Questionnaire in a Spanish Sample
2019
This paper analyzes the factorial and predictive validity of a Spanish adaptation of the College Persistence Questionnaire (SCPQ) on the retention of first year students (FYS) at university. The participants were 490 FYS from two public universities in Southern Europe (Spain). Factorial analysis of the SCPQ (&chi
Modelo predictivo preliminar para la identificación de pacientes con oportunidades de mejora farmacoterapéutica
2010
Objective: To develop a prediction model for identifying patients with the possibility of improving pharmacotherapy during the process of pharmaceutical validation of the prescription. Method: Cross-sectional study over two months, performed in the Internal Medicine and Infectious Disease divisions. Detecting opportunities for improving quality of pharmaco¬therapy is done by means of a pharmacist's validation of the prescription. Based on the information we obtained through this process, we performed a multivariate logistic regression analysis using as prognostic factors the demographic, pharmacotherapy and clinical variables related to identifying any drug-related problems (DRPs) in the pa…
