Malnutrición asociada a disfagia orofaríngea en pacientes mayores de 65 años ingresados en una unidad médico-quirúrgica
(Enfermería Clínica, 2014) Susi García, María Del Rosario; Martínez Rincón, María Del Carmen; Morena López, Felipe de la; Cortázar Sáez, Milagros; Santander Vaquero, Cecilio; Galán Sánchez-Heredero, María José
Objetivos: El objetivo principal es conocer la relación existente entre disfagia orofaríngea, situación de riesgo nutricional y deterioro funcional en pacientes mayores de 65 años ingresados en una unidad de hospitalización médico-quirúrgica. Los objetivos secundarios son determinar la prevalencia de disfagia orofaríngea, conocer el estado nutricional y la capacidad funcional de estos pacientes. Metodología: Estudio observacional, analítico y transversal que incluyó durante los meses de febrero a marzo del 2013 a pacientes mayores de 65 años ingresados en la unidad de Digestivo-Urología del Hospital Universitario de la Princesa. Se registraron las siguientes variables: edad, sexo, índice de masa corporal, soporte familiar, diagnóstico, comorbilidad, disfagia orofaríngea (EAT-10 y método de evaluación clínica volumen-viscosidad), malnutrición (Mininutritional Assessment) y capacidad funcional de los pacientes (índice de Barthel). Resultados: Se reclutó a 167 pacientes, siendo la prevalencia de disfagia y de malnutrición del 30,8 y 15,4% respectivamente. En pacientes con disfagia orofaríngea la prevalencia de problemas nutricionales aumentó hasta el 75%. En el análisis de regresión logística, la obtención de una puntuación baja en el índice de Barthel (OR 0,97 [IC 95%; 0,95-0,99]), la presencia de comorbilidad (OR 7,98 [IC 95%; 3,09-20,61]) y padecer disfagia (OR 4,07 [IC 95%; 1,57-10,52]) se asociaron a una mayor probabilidad de padecer malnutrición. Discusión: La disfagia orofaríngea es uno de los problemas más infradiagnosticados y subestimados entre los pacientes ancianos y que mayor afectación tiene sobre su estado nutricional. Sugerimos detectarla de forma precoz mediante los métodos diagnósticos establecidos y con la colaboración de un equipo multidisciplinar.

The Computer-Vision Symptom Scale (CVSS17): Development and Initial Validation
(IOVS (Investigative Ophthalmology & Vision Science, 2014) González Pérez, Mariano; Susi García, María Del Rosario; Antona Peñalba, Beatriz; Barrio de Santos, Ana Rosa; González Díaz-Obregón, Enrique
Purpose.: To develop a questionnaire (in Spanish) to measure computer-related visual and ocular symptoms (CRVOS). Methods.: A pilot questionnaire was created by consulting the literature, clinicians, and video display terminal (VDT) workers. The replies of 636 subjects completing the questionnaire were assessed using the Rasch model and conventional statistics to generate a new scale, designated the Computer-Vision Symptom Scale (CVSS17). Validity and reliability were determined by Rasch fit statistics, principal components analysis (PCA), person separation, differential item functioning (DIF), and item–person targeting. To assess construct validity, the CVSS17 was correlated with a Rasch-based visual discomfort scale (VDS) in 163 VDT workers, this group completed the CVSS17 twice in order to assess test-retest reliability (two-way single-measure intraclass correlation coefficient [ICC] and their 95% confidence intervals, and the coefficient of repeatability [COR]). Results.: The CVSS17 contains 17 items exploring 15 different symptoms. These items showed good reliability and internal consistency (mean square infit and outfit 0.88–1.17, eigenvalue for the first residual PCA component 1.37, person separation 2.85, and no DIF). Pearson's correlation with VDS scores was 0.60 (P < 0.001). Intraclass correlation coefficient for test–retest reliability was 0.849 (95% confidence interval [CI], 0.800–0.887), and COR was 8.14. Conclusions.: The Rasch-based linear-scale CVSS17 emerged as a useful tool to quantify CRVOS in computer workers.
Bayesian reasoning with emotional material in patients with schizophrenia
(Frontiers in Psychology, 2022) Susi García, María Del Rosario; Romero-Ferreiro, Verónica; Sánchez-Morla, Eva M.; Marí-Beffa, Paloma; Rodríguez-Gómez, Pablo; Amador Pacheco, Julia; Moreno, Eva M.; Romero, Carmen; Martínez-García, Natalia; Rodriguez-Jimenez, Roberto
Delusions are one of the most classical symptoms described in schizophrenia. However, despite delusions are often emotionally charged, they have been investigated using tasks involving non-affective material, such as the Beads task. In this study we compared 30 patients with schizophrenia experiencing delusions with 32 matched controls in their pattern of responses to two versions of the Beads task within a Bayesian framework. The two versions of the Beads task consisted of one emotional and one neutral, both with ratios of beads of 60:40 and 80:20, considered, respectively, as the "difficult" and "easy" variants of the task. Results indicate that patients showed a greater deviation from the normative model, especially in the 60:40 ratio, suggesting that more inaccurate probability estimations are more likely to occur under uncertainty conditions. Additionally, both patients and controls showed a greater deviation in the emotional version of the task, providing evidence of a reasoning bias modulated by the content of the stimuli. Finally, a positive correlation between patients' deviation and delusional symptomatology was found. Impairments in the 60:40 ratio with emotional content was related to the amount of disruption in life caused by delusions. These results contribute to the understanding of how cognitive mechanisms interact with characteristics of the task (i.e., ambiguity and content) in the context of delusional thinking. These findings might be used to inform improved intervention programs in the domain of inferential reasoning.
Características del parto y resultados neonatales en mujeres inmigrantes
(Metas de enfermería, 2016) Maroto Alonso, Virginia; Patiño Maraver, Vicente Manuel; Susi García, María Del Rosario; Álvarez Plaza, Consuelo
Objetivo: identificar las características específicas del parto y resultados neonatales según la nacionalidad de las mujeres en el Hospital Infanta Cristina de Parla (Madrid). Método: estudio observacional longitudinal con recogida retrospectiva de información, utilizando datos de 404 partos (202 de mujeres gestantes españolas y 202 de mujeres gestantes inmigrantes) asistidos en el Servicio de Ginecología y Obstetricia del Hospital Infanta Cristina de la localidad de Parla (Madrid) durante los años 2012 y 2013. Resultados: la población inmigrante proviene de hasta 30 países diferentes. Las mujeres gestantes africanas son el grupo mayoritario (37%), seguidas por americanas (28%), resto de Europa (19%) y Asia (16%). Las mujeres gestantes inmigrantes del área de salud estudiada tienen menor edad (media 29 años (DE: 5,1)), menor duración de la gestación (media 39,2 semanas DE: 1,2), menor índice de utilización de analgesia epidural (71,8%) y neonatos con mayor peso (peso medio 3.352 g DE: 431) que las mujeres gestantes españolas, de manera estadísticamente significativa. Los resultados obstétricos y perinatales referentes al tipo de registro cardiotocográfico, tipo de parto, pinzamiento de cordón umbilical, test de Apgar, pH de arteria umbilical y tipo de reanimación neonatal no presentan diferencias significativas entre inmigrantes y españolas. Conclusiones: las mujeres gestantes inmigrantes del área estudiada presentan características obstétricas similares a las españolas. A diferencia de las españolas son más jóvenes, utilizan menos la analgesia epidural y sus recién nacidos presentan mayor peso al nacimiento.
From linear questionnaires to computer-adaptive tests: Content development and calibration of the Digital Eye Strain Computer Adaptive Test (DESCAT)
(2022) Susi García, María Del Rosario; González Pérez, Mariano; Barrio De Santos, Ana Rosa; Antona Peñalba, Beatriz
We published in 2015 a linear Rasch-based scale (Computer Vision Symptom Scale, aka CVSS17) for measuring the computer-related visual and ocular symptoms in workers using video-display terminals. Because Computer adaptive testing (CAT) is currently considered a more efficient and less time-consuming (for test-takers) method than traditional linear questionnaires, we decided to create a new CAT for assessing these symptoms in general population. Therefore, the aim of our study is to identify content for this new CAT and to calibrate the items included in it.
A three-dimensional Oral health-related quality of life framework for temporomandibular joint disorders: A structural analysis of the Oral Health Impact Profile-14
(Journal of Dentistry, 2023) Castaño Joaquí, Oscar Gabriel; Susi García, María Del Rosario; Amador Pacheco, Julia
Objectives: the objective is to analyze the structure and relationship between the components of the Oral healthrelated quality of life using the Oral Health Impact Profile-14 (OHIP-14) for patients with temporomandibular joint disorders (TMJD). Methods: two studies were examinated by means of factor analysis, multidimensional scaling and their spatial display in a cross-sectional design (n = 153). Results: three-dimensional solutions with an adequate fit were found: residual distribution, root mean square of residuals (RMSR) = 0.04, Goodness of Fit Index (GFI) = 0.96, and Adjusted Goodness of Fit Index (AGFI) = 0.93; and Stress I = 0.023, respectively. The overall ordinal alpha coefficient was 0.92 (CI=0.90 to 0.94). The ordinal alpha coefficients for functional impact, psychosocial impact and psychological impact factors were 0.87 (CI=0.84 to 0.90), 0.88 (CI=0.84 to 0.91) and 0.78 (CI= 0.72 to 0.83), respectively. Item 9 was the most central, followed by 7 and 11. Items 1 and 2 had minor associations. There was no evidence of differences between centers: edge weight differences (M = 0.226, p = 0.94), global strength invariance test (S = 1.88, p = 0.1), centrality invariance test (p >0.05), edge invariance test (p >0.05). Conclusions: the links between the dimensions and the items seem to involve psychological components. Oral health-related quality of life emerged as a three-dimensional structure (Functional Impact, Psychosocial Impact and Psychological Impact) of functional and psychosocial elements in which physical, psychological, and social disability were essential, while theoretical functional limitation was least important. Clinical significance: the three-dimensional OHRQoL system for temporomandibular disorders (TMD) is a worthwhile alternative to interpret psychological and psychosocial aspects.

Five levels of performance and two subscales identified in the computer-vision symptom scale (CVSS17) by Rasch, factor, and discriminant analysis
(PLoS ONE, 2018) González Pérez, Mariano; Susi García, María Del Rosario; Barrio De Santos, Ana Rosa; Antona Peñalba, Beatriz
Purpose: To quantify the levels of performance (symptom severity) of the computer-vision symptom scale (CVSS17), confirm its bifactorial structure as detected in an exploratory factor analysis, and validate its factors as subscales. Methods: By partial credit model (PCM), we estimated CVSS17 measures and the standard error for every possible raw score, and used these data to determine the number of different performance levels in the CVSS17. In addition, through discriminant analysis, we checked that the scale's two main factors could classify subjects according to these determined levels of performance. Finally, a separate Rasch analysis was performed for each CVSS17 factor to assess their measurement properties when used as isolated scales. Results: We identified 5.8 different levels of performance. Discriminant functions obtained from sample data indicated that the scale's main factors correctly classified 98.4% of the cases. The main factors: Internal symptom factor (ISF) and external symptom factor (ESF) showed good measurement properties and can be considered as subscales. Conclusion: CVSS17 scores defined five different levels of performance. In addition, two main factors (ESF and ISF) were identified and these confirmed by discriminant analysis. These subscales served to assess either the visual or the ocular symptoms attributable to computer use.
