RESUMEN

Two types of cost-efficient antennas based on dielectric gradient index dielectric lens have been designed for 5G applications at 28 GHz. The first is a linearly polarized flat lens antenna (LP-FLA) for terrestrial 5G communications. The second is a novel circularly polarized stepped lens antenna (CP-SLA) for 5G satellite services. An efficient design method is presented to optimize and conform the lens topology to the radiation pattern coming from the antenna feeder. The LP-FLA is fed by a traditional linearly polarized pyramidal horn antenna (PHA). The CP-SLA is fed by an open-ended bow-tie waveguide cavity (BCA) antenna. This cavity feeder (BCA), using cross-sections with bow-tie shapes, allows having circular polarization at the desired frequency bandwidth. The two types of presented antennas have been manufactured in order to verify their performance by an easy, low-cost, three-dimensional (3D) printing technique based on stereolithography. The peak realized gain value for the flat (LP-FLA) and stepped (CP-SLA) lens antennas have been increased at 28 GHz to 25.2 and 24.8 dBi, respectively, by disposing the lens structures at the appropriated distance from the feeders. Likewise, using an array of horns (PHA) or open-ended bow-tie waveguide cavity (BCA) antenna feeders, it is possible to obtain a maximum steering angle range of 20° and 35°, for a directivity over 15 dBi and 10 dBi, in the planar and stepped lens antennas, respectively.

RESUMEN

Introduction: Our work describes the frequency of superinfections in COVID-19 ICU patients and identifies risk factors for its appearance. Second, we evaluated ICU length of stay, in-hospital mortality and analyzed a subgroup of multidrug-resistant microorganisms (MDROs) infections. Methods: Retrospective study conducted between March and June 2020. Superinfections were defined as appeared ≥48h. Bacterial and fungal infections were included, and sources were ventilator-associated lower respiratory tract infection (VA-LRTI), primary bloodstream infection (BSI), secondary BSI, and urinary tract infection (UTI). We performed a univariate analysis and a multivariate analysis of the risk factors. Results: Two-hundred thirteen patients were included. We documented 174 episodes in 95 (44.6%) patients: 78 VA-LRTI, 66 primary BSI, 9 secondary BSI and 21 UTI. MDROs caused 29.3% of the episodes. The median time from admission to the first episode was 18 days and was longer in MDROs than in non-MDROs (28 vs. 16 days, p<0.01). In multivariate analysis use of corticosteroids (OR 4.9, 95% CI 1.4–16.9, p 0.01), tocilizumab (OR 2.4, 95% CI 1.1–5.9, p 0.03) and broad-spectrum antibiotics within first 7 days of admission (OR 2.5, 95% CI 1.2–5.1, p<0.01) were associated with superinfections. Patients with superinfections presented respect to controls prolonged ICU stay (35 vs. 12 days, p<0.01) but not higher in-hospital mortality (45.3% vs. 39.7%, p 0.13). Conclusions: Superinfections in ICU patients are frequent in late course of admission. Corticosteroids, tocilizumab, and previous broad-spectrum antibiotics are identified as risk factors for its development.(AU)

Introducción: Nuestro trabajo describe la frecuencia de sobreinfecciones en pacientes con COVID-19 en UCI e identifica factores de riesgo asociados con su aparición. Secundariamente, evaluamos la estancia en UCI, mortalidad intrahospitalaria y analizamos un subgrupo de infecciones causadas por microorganismos multirresistentes (MDR). Métodos: Estudio realizado entre marzo y junio de 2020. Definimos como sobreinfección a aquellas que aparecieron ≥48h del ingreso. Incluimos las causadas por bacterias y hongos y evaluamos la infección respiratoria asociada a la ventilación mecánica (IRAVM), bacteriemia primaria, bacteriemia secundaria e infección del tracto urinario. Se realizó un análisis multivariante de los factores de riesgo. Resultados: Incluimos 213 pacientes, documentándose 174 episodios de sobreinfección en 95 casos (44,6%): IRAVM 78 episodios, bacteriemia primaria 66, bacteriemia secundaria 9 e ITU 21. Los MDR causaron el 29,3% de los episodios. La mediana de tiempo hasta el primer episodio fue de 18 días, siendo mayor en las causadas por MDR vs. no MDR (28 vs. 16, p<0,01). El análisis multivariante identificó la administración de corticoides (OR 4,9 IC 95% 1,4-16,9), tocilizumab (OR 2,4 IC 95% 1,1-5,9) y antibióticos de amplio espectro (OR 2,5 IC 95% 1,2-5,1) como factores de riesgo asociados. Los pacientes con sobreinfección presentaron una estancia en UCI más prolongada (35 vs. 12 días, p <0,01) pero no mayor mortalidad intrahospitalaria (45,3% vs. 39,7%, p 0,13). Conclusiones: Las sobreinfecciones en los pacientes con COVID-19 aparecen tardíamente. La administración de corticoides, tocilizumab y antibióticos de amplio espectro se asocia con su aparición.(AU)

RESUMEN

BACKGROUND: The use of Android mobile applications aimed at addressing users' psychological health is increasing. However, no review has been conducted on public Android commercial telepsychological applications in Spain. METHOD: A systematic search was carried out in the general applications section of Google Play Store based on 20 keywords in Spanish. Applications in Spanish or English that were relevant from the perspective of the search terms were included in the analysis. RESULTS: Of the 1,000 applications retrieved, only 43.59% (337/773) met the inclusion criteria, of which 49.26% (171/337) were Spanish. Most of them were Self-applied treatment applications (52.96%, 29.59%, Spanish; 23.37%, English). A total of 69.44% (37.38% Spanish; 31.95% English) did not indicate the origin of the information and the academic link was anecdotal (3.25%). CONCLUSIONS: The low percentage of relevant applications, high prevalence of self-help applications, absence of references on the origin of the information, absence of academic support, and lack of certifications encouraged us to recommend caution to consumers and professionals in their adoption of these applications for the treatment of any psychological disorder.

RESUMEN

BACKGROUND: Anti-SARS-CoV-2 S antibodies prevent viral replication. Critically ill COVID-19 patients show viral material in plasma, associated with a dysregulated host response. If these antibodies influence survival and viral dissemination in ICU-COVID patients is unknown. PATIENTS/METHODS: We studied the impact of anti-SARS-CoV-2 S antibodies levels on survival, viral RNA-load in plasma, and N-antigenaemia in 92 COVID-19 patients over ICU admission. RESULTS: Frequency of N-antigenaemia was >2.5-fold higher in absence of antibodies. Antibodies correlated inversely with viral RNA-load in plasma, representing a protective factor against mortality (adjusted HR [CI 95%], p): (S IgM [AUC ≥ 60]: 0.44 [0.22; 0.88], 0.020); (S IgG [AUC ≥ 237]: 0.31 [0.16; 0.61], <0.001). Viral RNA-load in plasma and N-antigenaemia predicted increased mortality: (N1-viral load [≥2.156 copies/ml]: 2.25 [1.16; 4.36], 0.016); (N-antigenaemia: 2.45 [1.27; 4.69], 0.007). CONCLUSIONS: Low anti-SARS-CoV-2 S antibody levels predict mortality in critical COVID-19. Our findings support that these antibodies contribute to prevent systemic dissemination of SARS-CoV-2.

RESUMEN

Background: Cognitive-behavioral family-based treatment (CBFT) is the treatment standard in very young children with obsessive-compulsive disorder (OCD), which includes the same core components of cognitive-behavioral therapy (CBT) with significant family involvement. Although the latter reports high rates of remission, some children do not improve with treatments. Therefore, it is necessary to identify possible moderating variables such as comorbidity, severity of disorder, years of onset, parental anxiety, and parental accommodation. This study has two main aims: (1) to propose a predictive model on family accommodation (father and mother), taking into account variables related to the children (severity of obsessive-compulsive responses, internalizing and externalizing symptoms, and comorbidity) and with the parents before intervention (worry, accommodation of one parental member over the other) and (2) to examine the mediating role of externalizing symptoms and mother's accommodation in the relation between initial severity and improvement of severity of obsessive-compulsive responses in children aged 5-8 years. Methods: Participants comprised 56 children with OCD [mean = 6.61 (SD = 0.76)] and their parents; 79% of the sample was men. Treatment was implemented by two clinicians specialized in OCD (>15 years of experience). Clinicians were trained to administer CBT protocol in the same way. They were doctors of clinical psychology and researchers at the OCD. Results: Mother's accommodation was associated with child variables (Child Behavior Checklist-Externalizing and Initial Severity, Children's Yale-Brown Obsessive-Compulsive Scale). Father's accommodation could be explained by parent variables (mother's accommodation and worry). Simple mediation model tested using the SPSS macro PROCESS supported the relation of the initial severity of symptoms with that following intervention, through the simple indirect effect of externalizing symptoms of the child. Conclusions: Comorbidities with externalizing symptoms, father's worry, and mother's accommodation were variables that should be controlled in treatment of pediatric OCD.

RESUMEN

Some recent waveguide-based antennas are presented in this paper, designed for the next generation of communication systems operating at the millimeter-wave band. The presented prototypes have been conceived to be manufactured using different state-of-the-art techniques, involving subtractive and additive approaches. All the designs have used the latest developments in the field of manufacturing to guarantee the required accuracy for operation at millimeter-wave frequencies, where tolerances are extremely tight. Different designs will be presented, including a monopulse antenna combining a comparator network, a mode converter, and a spline profile horn; a tunable phase shifter that is integrated into an array to implement reconfigurability of the main lobe direction; and a conformal array antenna. These prototypes were manufactured by diverse approaches taking into account the waveguide configuration, combining parts with high-precision milling, electrical discharge machining, direct metal laser sintering, or stereolithography with spray metallization, showing very competitive performances at the millimeter-wave band till 40 GHz.

RESUMEN

Background/Objective: Research on selective mutism (SM) has been limited by the absence of standardised, psychometrically sound and cross-culturally valid assessment measures. Our aim is to present the results of a study of the factor structure and the reliability and concurrent validity of the scores of the Selective Mutism Questionnaire (SMQ), translated and adapted into Spanish. The SMQ contains 17 items about children's difficulty in speaking adequately in the family, school and social environment (out-of-school and out-of-family), each of which is answered according to a Likert scale with four response alternatives on speech frequency. Method: The study involved 110 pairs of parents of children diagnosed with SM whose ages ranged from 3 to 10 years. Results: The results show that the data from the Spanish sample fit the factorial model obtained by Bergman et al., and that data on its reliability and validity are robust and confirm that it as a good instrument for assessing SM in Spanish-speaking children. Conclusions: Therefore, we can affirm that the SMQ is a good instrument to assess SM in Spanish-speaking children. (AU)

Antecedentes/Objetivo: La investigación sobre el mutismo selectivo (MS) se ha visto limitada por la ausencia de medidas de evaluación estandarizadas, psicométricamente sólidas y con validez transcultural. Nuestro objetivo es presentar los resultados de un estudio de la estructura factorial, fiabilidad y validez concurrente de las puntaciones del Selective Mutism Questionnaire (SMQ), traducido y adaptado al español. El SMQ contiene 17 ítems sobre la dificultad de los niños para hablar adecuadamente en el ámbito familiar, escolar y social (extraescolar y ajeno al ámbito familiar), cada uno de los cuales se contesta según una escala tipo Likert con cuatro alternativas de respuesta sobre la frecuencia del habla. Método: En el estudio participaron 110 parejas de padres de niños y niñas diagnosticados con MS. Resultados: Los resultados muestran que los datos de la muestra española se ajustan al modelo factorial obtenido por Bergman et al., así como que los datos sobre su fiabilidad y la validez son robustos. Conclusiones: Por todo ello podemos afirmar que el SMQ es un buen instrumento para valorar el MS en niños y niñas españoles de habla castellana. (AU)

RESUMEN

BACKGROUND: The main aim was to examine changes in coping strategies, anxiety and depression in obsessive-compulsive and schizophrenia patients during COVID-19, in addition to controlling the influence of intolerance to uncertainty and experiential avoidance. METHOD: The first time, the study comprised (15-30 April 2020) 293 patients, 113 of whom were diagnosed with obsessive-compulsive disorder, 61 with schizophrenia and 119 healthy controls, aged 13-77 years (M = 37.89, SD = 12.65). The second time (15-30 November), the study comprised 195 participants (85 obsessive-compulsive patients, 42 schizophrenic patiens and 77 healthy controls participants). The evaluation was carried out through an online survey. RESULTS: The clinical groups worsened over time in cognitive coping, anxiety and depression, while the control group only worsened in depression. Intergroup differences in anxiety, depression and coping strategies were maintained, highlighting the use of some maladaptive strategies (avoidance, spiritual) in clinical groups. Experiential avoidance and tolerance for uncertainty mainly affected coping. CONCLUSIONS: The duration of COVID-19 not only produced changes in anxiety and depression in clinical groups but also in coping strategies to face this pandemic and its consequences.

RESUMEN

BACKGROUND: Coronavirus disease (COVID-19) with acute respiratory distress syndrome is a life-threatening condition. A previous diagnosis of chronic liver disease is associated with poorer outcomes. Nevertheless, the impact of silent liver injury has not been investigated. We aimed to explore the association of pre-admission liver fibrosis indices with the prognosis of critically ill COVID-19 patients. METHODS: The work presented was an observational study in 214 patients with COVID-19 consecutively admitted to the intensive care unit (ICU). Pre-admission liver fibrosis indices were calculated. In-hospital mortality and predictive factors were explored with Kaplan-Meier and Cox regression analysis. RESULTS: The mean age was 59.58 (13.79) years; 16 patients (7.48%) had previously recognised chronic liver disease. Up to 78.84% of patients according to Forns, and 45.76% according to FIB-4, had more than minimal fibrosis. Fibrosis indices were higher in non-survivors [Forns: 6.04 (1.42) versus 4.99 (1.58), p < 0.001; FIB-4: 1.77 (1.17) versus 1.41 (0.91), p = 0.020)], but no differences were found in liver biochemistry parameters. Patients with any degree of fibrosis either by Forns or FIB-4 had a higher mortality, which increased according to the severity of fibrosis (p < 0.05 for both indexes). Both Forns [HR 1.41 (1.11-1.81); p = 0.006] and FIB-4 [HR 1.31 (0.99-1.72); p = 0.051] were independently related to survival after adjusting for the Charlson comorbidity index, APACHE II, and ferritin. CONCLUSION: Unrecognised liver fibrosis, assessed by serological tests prior to admission, is independently associated with a higher risk of death in patients with severe COVID-19 admitted to the ICU.

RESUMEN

Background/Objective: The main aim of this study was to compare coping strategies in obsessive-compulsive disorder (OCD) patients and a healthy control group during COVID-19 lockdown and to analyze the relationship with some variables which may influence results (depression, anxiety, comorbidity, subtype of obsession-compulsion). Method: There were 237 participants, 122 OCD and 115 healthy controls, aged 17-61 years old (M = 33.48, SD = 11.13). Results: Groups showed differences in the use of some adaptive strategies (positive reinterpretation, acceptance, humor) and maladaptive (denial, self-blame). Within obsessive-compulsive group, comorbidity affected the greater use of inappropriate strategies (denial, substance abuse and self-blame) while type of obsession-compulsion did not influence use. Anxiety and depression levels were related to the use of less adaptive strategies. Conclusions: These findings strengthen the need for training in the use of effective and adaptive coping strategies, making it necessary to improve clinical follow-up of these patients. It is relevant to be in contact with healthcare professionals, review medication and observe the anxiety and depression levels. (AU)

Antecedentes/Objetivo: El objetivo de este estudio fue comparar las estrategias de afrontamiento utilizadas por pacientes con Trastorno obsesivo-compulsivo (TOC) durante el confinamiento debido a la COVID-19 frente a controles sanos y analizar su relación con algunas variables que pueden influir en los resultados (ansiedad, depresión, comorbilidad, tipo de obsesiones-compulsiones). Método: Los participantes fueron 237, 122 diagnosticados de Trastorno obsesivo-compulsivo y 115 controles sanos, con edades comprendidas entre 13 y 58 años (M = 34,60, DT = 10,41). Resultados: Los grupos presentaron diferencias en el uso de algunas estrategias adaptativas (reinterpretación positiva, aceptación, humor) y desadaptativas (negación, autoculpa). Dentro del grupo TOC, la comorbilidad afectó para el mayor uso de estrategias inadecuadas (negación, abuso de sustancias y autoculpa), mientras que el tipo de obsesiones-compulsiones no influyó en el uso de las mismas. Los niveles de ansiedad y depresión estaban relacionadas con el uso de estrategias menos adaptativas. Conclusiones: Estos hallazgos refuerzan la necesidad de entrenar en la utilización de estrategias de afrontamiento eficaces y adaptativas, siendo necesario mejorar el seguimiento clínico de estos pacientes. Es importante estar en contacto con profesionales de la salud, revisar la medicación y observar los niveles de ansiedad y depresión. (AU)

RESUMEN

This study analyzed response inhibition, cognitive flexibility and working memory in three groups of patients diagnosed with obsessive-compulsive disorder, social anxiety disorder and generalized anxiety disorder, considering some variables that may influence results (nonverbal reasoning, comorbidity, use of pharmacotherapy). Neuropsychological measures were completed using a computerized Wisconsin card sorting test, Stroop color word test, go/no-go task, digits and Corsi. Significant differences were obtained among groups in cognitive flexibility and working memory variables. The obsessive-compulsive disorder (OCD) group showed the worst results. The social anxiety disorder group obtained greater effect sizes in visuospatial memory. However, significant differences between groups in visuospatial memory were no longer present when nonverbal reasoning was controlled. Comorbidity influenced interference in the OCD and generalized anxiety disorder (GAD) groups. In addition, the executive functions were differently influenced by the level of obsessions and anxiety, and the use of pharmacotherapy. Study limitations include a non-random selection of participants, modest sample size and design type (cross-sectional). The OCD group showed the worst results in flexibility cognitive and verbal working memory. Comorbidity, use of pharmacotherapy and level anxiety and obsessions were variables influencing the performance of executive functions.

RESUMEN

BACKGROUND: Cognitive flexibility, response inhibition, and working memory are considered the main mechanisms responsible for executive control. This study examined differences in cognitive flexibility, inhibition, and working memory in patients with obsessive-compulsive disorder (OCD) relative to a control group. METHOD: A total of 62 obsessive-compulsive participants (OCD = 32; healthy control = 32) aged between 17 and 56 years old (M = 33.16, SD = 9.23) were administered the computerized Wisconsin Card Sorting Test, Stroop Color-Word Test, Go/No-Go Task, Digit Test, and Corsi Block Test. Clinician-rated and self-reported obsessive-compulsive symptom severity, and anxiety, depression, and obsessive beliefs were evaluated. RESULTS: The control group performed better than the OCD group in tasks involving cognitive flexibility, inhibition, and visuospatial working memory. Anxiety and obsessive beliefs influenced the participants' performance on inhibition and working memory tasks. Similarly, comorbidity also influenced inhibition and working memory. In addition, the use of pharmacotherapy and the degree of OCD symptom severity influenced verbal working memory. CONCLUSIONS: Cognitive flexibility, inhibition, and visuospatial working memory deficits may be endophenotypes of OCD but require further examination for specificity. OCD severity, comorbidity patterns, anxiety, and obsessive beliefs may influence performance.

RESUMEN

The main aim of this study was to compare coping strategies in obsessive-compulsive disorder (OCD) patients and a healthy control group during COVID-19 lockdown and to analyze the relationship with some variables which may influence results (depression, anxiety, comorbidity, subtype of obsession-compulsion). METHOD: There were 237 participants, 122 OCD and 115 healthy controls, aged 17-61 years old (M = 33.48, SD = 11.13). RESULTS: Groups showed differences in the use of some adaptive strategies (positive reinterpretation, acceptance, humor) and maladaptive (denial, self-blame). Within obsessive-compulsive group, comorbidity affected the greater use of inappropriate strategies (denial, substance abuse and self-blame) while type of obsession-compulsion did not influence use. Anxiety and depression levels were related to the use of less adaptive strategies. CONCLUSIONS: These findings strengthen the need for training in the use of effective and adaptive coping strategies, making it necessary to improve clinical follow-up of these patients. It is relevant to be in contact with healthcare professionals, review medication and observe the anxiety and depression levels.

El objetivo de este estudio fue comparar las estrategias de afrontamiento utilizadas por pacientes con Trastorno obsesivo-compulsivo (TOC) durante el confinamiento debido a la COVID-19 frente a controles sanos y analizar su relación con algunas variables que pueden influir en los resultados (ansiedad, depresión, comorbilidad, tipo de obsesiones-compulsiones). Método: Los participantes fueron 237, 122 diagnosticados de Trastorno obsesivo-compulsivo y 115 controles sanos, con edades comprendidas entre 13 y 58 años (M = 34,60, DT = 10,41). Resultados: Los grupos presentaron diferencias en el uso de algunas estrategias adaptativas (reinterpretación positiva, aceptación, humor) y desadaptativas (negación, autoculpa). Dentro del grupo TOC, la comorbilidad afectó para el mayor uso de estrategias inadecuadas (negación, abuso de sustancias y autoculpa), mientras que el tipo de obsesiones-compulsiones no influyó en el uso de las mismas. Los niveles de ansiedad y depresión estaban relacionadas con el uso de estrategias menos adaptativas. Conclusiones: Estos hallazgos refuerzan la necesidad de entrenar en la utilización de estrategias de afrontamiento eficaces y adaptativas, siendo necesario mejorar el seguimiento clínico de estos pacientes. Es importante estar en contacto con profesionales de la salud, revisar la medicación y observar los niveles de ansiedad y depresión.

RESUMEN

La deficiente percepción, comprensión y regulación de las emociones suele jugar un papel muy relevante en el desarrollo y mantenimiento de los trastornos psicopatológicos. El objetivo de este estudio fue analizar las diferencias en atención, compresión, regulación de emociones e ira, controlando algunas variables que podían influir en los resultados (edad, ansiedad y depresión). Participaron 315 adolescentes (213 chicos y 102 chicas) de entre 12 y 18 años de edad (M= 14,92; DT= 1,98), con altas (≥ percentil 90) y bajas (< percentil 21) puntuaciones en la dimensión Obsesión-compulsión del “Cuestionario de 90 síntomas” (SCL-90-R; Derogatis, 1975). Se alcanzaron diferencias estadísticamente significativas entre los grupos en todas las variables de inteligencia emocional e ira, excepto en expresión interna de ira y expresión física de ira. La edad, la ansiedad y la depresión influyeron en algunas de las variables. Estos hallazgos son relevantes de cara a la implementación de tratamientos (AU)

Poor perception, understanding and regulation of emotions often play a key role in the development and maintenance of psychopathological disorders. The aim of this study was to analyze differences in attention, compression, regulation of emotion and anger, taking into account some variables that may influence results (age, anxiety and depression). Participants were 315 adolescents (213 boys and 102 girls) aged between 12 and 18 years old (M= 14.92, SD= 1.98), high (≥ 90th percentile) and low (< percentile 21) ratings in obsessive-compulsive dimension in The Symptom Check List (SCL-90-R; Derogatis, 1975). Statistically significant differences between groups were observed in emotions and anger variables except internal expression of anger and physical expression of anger. Age, anxiety and depression influenced some variables. These findings are relevant for treatment (AU)
