RESUMEN
The diagnostic criteria, treatments at the time of admission, and drugs used in patients with acute coronary syndrome are well defined in countless guidelines. However, there is uncertainty about the measures to recommend during patient discharge planning. This document brings together the most recent evidence and the standardized and optimal treatment for patients at the time of discharge from hospitalization for an acute coronary syndrome, for comprehensive and safe care in the patient's transition between care from the acute event to the outpatient care, with the aim of optimizing the recovery of viable myocardium, guaranteeing the most appropriate secondary prevention, reducing the risk of a new coronary event and mortality, as well as the adequate reintegration of patients into daily life.
Los criterios diagnósticos, los tratamientos en el momento de la admisión y los fármacos utilizados en pacientes con síndrome coronario agudo están bien definidos en innumerables guías. Sin embargo, existe incertidumbre acerca de las medidas para recomendar durante la planificación del egreso de los pacientes. Este documento reúne las evidencias más recientes y el tratamiento estandarizado y óptimo para los pacientes al momento del egreso de una hospitalización por un síndrome coronario agudo, para un cuidado integral y seguro en la transición del paciente entre la atención del evento agudo y el cuidado ambulatorio, con el objetivo de optimizar la recuperación de miocardio viable, garantizar la prevención secundaria más adecuada, reducir el riesgo de un nuevo evento coronario y la mortalidad, así como la adecuada reinserción de los pacientes en la vida cotidiana.

Theories of psychopathy development traditionally emphasize that individuals high in psychopathy experience diminished internalizing symptoms (e.g., anxiety and depression). However, many studies find null or even positive relationships between psychopathy and internalizing. The current meta-analysis therefore aimed to provide a comprehensive understanding of heterogeneity in psychopathy-anxiety/depression relationships by examining measurement and sample-related variables that may moderate these associations (e.g., psychopathy subdimensions assessed, different measures/operationalizations of psychopathy and anxiety/depression, and demographic characteristics). Results suggest that psychopathy demonstrates a small, positive overall association with anxiety/depression (r = 0.09), which may indicate that psychopathy is unrelated to subjective experiences of anxiety and sadness, but results could also reflect that varying psychopathy and anxiety/depression assessment practices contribute to heterogeneity in psychopathy-anxiety/depression associations. Most notably, results indicate that associations vary substantially across different measures/operationalizations of psychopathy, even when controlling for sample type and informant. Some psychopathy scales could therefore inadvertently capture anxiety/depression symptoms or broader psychopathology in addition to psychopathic traits. Findings from the current meta-analysis can inform future efforts to understand how measurement-related considerations influence relationships between psychopathy and anxiety/depression.

Introducción: los trastornos del sueño en Pediatría son un problema creciente. La melatonina es el producto de elección y es común recibir publicidad de múltiples productos que la contienen. En este texto se lleva a cabo un análisis comparativo de los mismos, examinando la evidencia científica más reciente, con el fin de determinar si está justificado o no su uso. Métodos: se ha realizado un estudio descriptivo de los productos que contenían melatonina comercializados en España, de venta en farmacias y dirigidos a la población pediátrica. Posteriormente, se ha llevado a cabo una revisión de documentos sobre el uso de melatonina en niños y sobre cada componente extra presente en los productos recogidos. Resultados: se analizaron 53 productos. La forma de administración mayoritaria fue en gotas o mililitros. La dosis recomendada habitual de melatonina fue de 1 mg al día. El componente añadido más frecuente registrado fue la vitamina B6, y melisa y pasiflora fueron las plantas más utilizadas. Ninguno de los productos estaba catalogado como fármaco por la Agencia Española de Medicamentos y Productos Sanitarios (AEMPS) y tampoco se encontró en la publicidad de ninguno referencias bibliográficas. Conclusiones: aunque es conocida la eficacia de la melatonina en trastornos del sueño, actualmente no hay un consenso sobre su dosis eficaz en edad pediátrica. Las sustancias que más frecuentemente se asocian a melatonina cuentan con poca bibliografía que respalde sus resultados sobre el sueño, además de que para ellas tampoco existen, de momento, dosis estandarizadas para la población infantil.

Introduction: sleep disorders in paediatrics are a growing problem. Melatonin is the drug of choice and it is common to receive advertising for multiple products containing melatonin in primary care. In this paper, a comparative analysis of these products is carried out, examining the most recent scientific evidence, in order to determine whether their use is justified or not. Methods: a descriptive study was conducted on melatonin-containing products sold in pharmacies in Spain and aimed at the paediatric population. Subsequently, a systematic review of documents on the use of melatonin in children and on each extra component present in the products collected was carried out. Results: fifty-three products were analysed. The most common form of administration was drops or millilitres. The usual recommended dose of melatonin was 1 mg per day. The most frequently reported added component was vitamin B6, and lemon balm and passionflower were the most frequently used herbs. None of the products were specifically listed in the Spanish Agency for Medicines and Health Products, and no bibliographical references were found in the advertising of any of the products. Conclusions: although the efficacy of melatonin in sleep disorders is well known, there is currently no consensus on its effective dose in children. The substances most frequently associated with melatonin have little literature to support their results in sleep, and there are no standardised doses for them either, or doses lower than these are used due to a lack of studies in the paediatric population.

The Proposed Specifiers for Conduct Disorder (PSCD; Salekin & Hare, 2016) is a new self-report and informant measure designed to assess psychopathic characteristic domains along with symptoms of conduct disorder in youth. Previous factor analytic studies on the PSCD have found that the items are accounted for by a four-factor model reflecting grandiose-manipulative, callous-unemotional, daring-impulsive, and conduct disorder (CD) symptoms. The present study examined the factor structure, psychometric properties, and criterion-related validity of the parent-report version of the PSCD (PSCD-P) in a nationally representative U.S. sample of children and adolescents (N = 1,091, Mage = 13.39, SD = 2.20, range age = 10-17; 50.0% boys, 76% White). Confirmatory factor analyses for the full (24-item) and a shortened (13-item) PSCD-P revealed good internal reliability estimates and support for the four-factor model (grandiose-manipulative, callous-unemotional, daring-impulsive, CD). Results also provided evidence for (a) measurement invariance of the PSCD-P items across sex, race/ethnicity, and age of the child; (b) convergent validity with CD/oppositional defiant disorder symptoms and discriminant validity with a measure of neuroticism; and (c) criterion-related validity with respect to prosociality, peer and family functioning, reactive and proactive aggression, delinquency, academic performance, and substance use. The prevalence for psychopathic personality propensity was found to be 2%. We discuss clinical and research implications regarding the use of the parent-report version of the PSCD for school-aged children. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The Proposed Specifiers for Conduct Disorder (PSCD; Salekin in Pers Disord: Theory Res Treat 7:180-191, 2016) scale was designed to assess interrelated psychopathic trait domains in conjunction with symptoms of Conduct Disorder (CD) in children and adolescents (i.e., grandiose-manipulative, callous-unemotional, daring-impulsive). Variable-centered studies have provided support for a four-factor PSCD structure (Salekin et al. in Psychol Assess 34(10):985-992, 2022) in line with other adolescent and adult studies. The current person-centered study used latent profile analysis of the PSCD domains to examine whether theoretically meaningful and empirically robust PSCD subtypes emerged from a diverse sample (70.9% White, 20.1% Black, 3.6% Hispanic, and 5.4% other) of adolescents (modal age = 17) in a military style residential facility (N = 409; Males = 80.6%). As hypothesized, a four-class solution was best, consistent with adult psychopathy subtyping research (Hare et al. in Handbook of Psychopathy 39-79, 2018; Roy et al. in Pers Disord: Theory Res Treat, in press). The PSCD subtype profiles were uniform across sex and race/ethnicity. Adolescents evincing a psychopathic trait propensity profile (elevated on all four PSCD domains) displayed the greatest number of arrests and higher overall externalizing psychopathology, compared to the other three latent classes, as well as higher internalizing psychopathology compared to adolescents with general delinquency. The PSCD provides a sound measure of psychopathic trait propensities in youth and our results offer investigators and clinicians a means for understanding person-centered psychopathic traits versus antisocial profiles among at-risk adolescents. Taken together, the current results may offer a viable approach for examining specific treatment targets based on PSCD subtype profiles.

Environmental radioactivity study was performed in unconventional hydrocarbons areas for the first time in Mexico, where four unconventional hydrocarbon exploratory wells (UHEW) are planned. This study assesses natural radiological conditions in areas around UHEW. Equivalent dose rate distribution displayed in Geographic Information System (GIS) had a maximum of 1.83 mSv a-1 and minimum of 0.04 mSv a-1, GIS was also used for introducing land usage, water resources and population occupancy. Measurements of gross alpha and gross beta in water were below the national permissible limits for drinking water 0.5 and 1.0 Bq L-1 respectively, even though samples do not correspond to drinking water. Evaluation of 238U and 226Ra in groundwater were below minimum detectable concentration 1.3 and 1.0 Bq L-1, respectively. This study provides a radiological baseline for the impact of future industrial activities, especially if exploitation of unconventional hydrocarbons produces naturally occurring radioactive material.

Child psychopathic traits appear to be associated with negative outcomes. Despite the study of youth psychopathy often relying on multiple reporters (e.g., child, caregivers, teachers), there is limited insight into how much information these various sources contribute and moreover, how this information is integrated. The present study sought to address this gap in the literature by examining the magnitude of relationships between self- and other-reported youth psychopathy and negative outcomes (e.g., delinquency, aggression) using a meta-analytic approach. Results revealed a moderate association between psychopathic traits and negative outcomes. Moderator analyses showed a greater relationship for other- than self-reported psychopathy, although not to a substantive extent. Results further indicated the magnitude of the overall psychopathy-negative outcomes association was stronger for externalizing than internalizing outcomes. Study findings can inform improvements in the assessment of youth psychopathy across research and practice, in addition to advancing our understanding of the utility of psychopathic traits in the prediction of clinically relevant outcomes. This review also provides guidance for future multisource raters and source-specific information in the study of psychopathy in youth.

The Proposed Specifiers for Conduct Disorder (PSCD) was developed as a measure to assess the multifaceted model of psychopathic traits in children/youth (i.e., grandiose-manipulative [GM], callous-unemotional [CU], and daring-impulsive [DI] traits) in addition to Conduct Disorder (CD) symptoms. This study aims to test the psychometric properties of the PSCD-self-report version across community (n = 648; 52.9% female) and forensic male youth (n = 258) from the Portuguese population. Results supported a general factor and four specific factors (GM, CU, DI, CD), which was invariant across gender and sample type. Evidence for reliability, construct, and temporal validity were also found. Overall, the PSCD appears to be a promising measure for assessing psychopathic traits in youth from both community and forensic settings, which may contribute to the discussion around the conceptualization, assessment, predictive value, and clinical usefulness of the multifaceted model of psychopathy in youthful populations, particularly in its association with CD.

The Proposed Specifiers for Conduct Disorder scale (PSCD; Salekin & Hare, 2016) is a new scale for the assessment of psychopathic characteristic domains in children and adolescents. The four domains are Grandiose-manipulative (GM), Callous-unemotional (CU), Daring-impulsive (DI), and Conduct Disorder (CD). We examined the properties of the self-report version of the PSCD in a large sample of adolescents (n = 409; age = 16-19; 80.6% male) in a military-style residential facility. Factor analytic results supported a four-factor model consistent with other PSCD research (e.g., López-Romero et al., 2019; Luo et al., 2021). Structural equation model (SEM) indicated a superordinate PSCD factor accounted for significant variance in self-reported delinquency history. The PSCD had good internal consistency and strong convergent and discriminant validity with measures of externalizing and internalizing disorders. The present study provides encouraging data that the PSCD may provide a sound measure of psychopathic propensities in youth. However, additional data are needed to test the stability of the PSCD.

Endovascular thrombectomy (EVT) for the treatment of acute ischemic stroke (AIS) remains an off-label procedure seldom utilized in the pediatric population; this holds especially true for patients presenting outside the standard 6-hour time window. In this review we describe the published literature regarding usage of the extended time window EVT in pediatric stroke. We searched PubMed for all pediatric AIS cases and case series that included patients treated with extended time window EVT. We found data from 38 cases found in 27 publications (15 case reports and 12 case series). The median age was 10 years; 60.5% males. The median NIHSS before EVT was 13 with a median time-to-treatment of 11 hours. The posterior circulation was involved in 50.0%. Stent retrievers were used in 68.5%, and aspiration in 13.2%. Angiographic outcome TICI ≥2B was achieved in 84.2%, whereas TICIË2B was reported in 10.6%. A favorable clinical outcome (NIHSS score ≤4, modified Rankin score ≤1, or Pediatric Stroke Outcome measure score ≤1) occurred in 84.2%. Eight cases that did not report the clinical outcome employing a standardized scale described mild to absent neurological residual deficits. This study found data that supports that extended window EVT produces high recanalization rates and good clinical outcomes in pediatric patients with AIS. Nevertheless, the source materials are indirect and contain substantial inconsistencies with an increased risk of bias that amount to low evidence strength.
RESUMEN
Background: Stroke is a leading cause of death and disability worldwide, particularly in low- and middle-income countries. We aimed to identify the main barriers to optimal acute management of stroke in a referral center. Methods: Demographic data was collected from patients assessed with acute stroke in the emergency department of the Instituto Nacional de Neurología y Neurocirugía (INNN) from January to June 2019. Additionally, a telephone interview was conducted with patients/primary caregiver to know which they considered the main reason for the delay in arrival at INNN since the onset of stroke. Results: 116 patients were assessed [age 65 ± 15 years, 67 (57.8%) men]. Patients consulted other facilities prior to arrival at INNN in 59 (50.9%) cases (range of hospitals visited 1-4), 83 (71.6%) arrived in a private car, with prenotification in only 4 (3.4%) of the total sample. The mean onset-to-door time was 17 h (45 min-10 days). Telephone interviews were done in 61 patients/primary caregivers, stating that they consider the multiple evaluations in other facilities [n = 26/61 (42.6%)] as the main reason for delay in arrival at the ED, followed by ignorance of stroke symptoms and treatment urgency [n = 21/61 (34.4%)]. Conclusion: In this small, retrospective, single center study, the main prehospital barrier to optimal acute management of stroke in a developing country is multiple medical evaluations prior to the patient's transport to a specialized stroke hospital, who mostly arrived in a private car and without prenotification. These barriers can be overcome by strengthening public education and improving patient transfer networks and telemedicine.
RESUMEN
Las proteínas y polisacáridos con frecuencia son utilizados simultáneamente en la industria de alimentos. Las interacciones entre ambos biopolímeros juegan un papel importante en la estructura y estabilidad de muchos alimentos procesados ya que pueden resultar en un sistema con propiedades bioactivas diferentes como ocurre en el caso de las funcionales. Objetivo. Evaluar los cambios en la capacidad antioxidante de un sistema hidrocoloide mixto formado por un hidrolizado enzimático proteico de frijol endurecido (P. vulgaris) y goma modificada de flamboyán (Delonix regia) (SHM). Materiales y métodos. El estudio se hizo entre febrero-octubre, 2014, en Mérida, México. Se modificó enzimáticamente el concentrado proteico de P. vulgaris con Pepsina-Pancreatina® y la goma extraída del flamboyán mediante carboximetilación, preparando dispersiones al 1% de cada uno de los biopolímeros, determinado la fluorescencia intrínseca de Trp (FIT) como indicador de la interacción entre ambos biopolímeros y la actividad antioxidante y quelante del sistema resultante. Resultados. Se obtuvo un hidrolizado proteico extensivo con 28,8% de grado de hidrólisis y una goma de flamboyán con grado de sustitución de 0,91. La mayor interacción entre ambos biopolímeros, se obtuvo empleando una relación 5:1 del SHM a pH 4 de acuerdo con el valor de FIT. Conclusiones. Los sistemas hidrocoloides mixtos preparados con hidrolizado extensivo de las proteínas Phaseolus vulgaris y goma modificada de flamboyán presentaron un incremento en la actividad antioxidante, respecto del hidrolizado dependiendo del mecanismo de oxidación, así como de las condiciones de pH en que se encuentra el sistema y la interacción entre ambos componentes(AU)
Proteins and polysaccharides are frequently used simultaneously in the food industry. The interactions between both biopolymers play an important role in the structure and stability of many processed foods since they can result in a system with different bioactive properties as in the case of functional ones. Objective. Evaluate the changes in the antioxidant capacity of mixed hydrocolloid system formed by a hard to cook bean (P. vulgaris) protein enzymatic hydrolyzate and modified flamboyant gum (Delonix regia) (SHM). Materials and methods. The study was conducted from February to October 2014 in Merida, Mexico. For this, the protein concentrate of P. vulgaris was treated with Pepsin-Pancreatin® and the gum extracted from the flamboyant were modified enzymatically by carboxymethylation, preparing 1% dispersions of each of the biopolymers, determining the intrinsic Trp fluorescence (FIT) as an indicator of the interaction between both biopolymers and the antioxidant and chelating activity of the resulting system. Results. The main results indicated that an extensive protein hydrolyzate with 28.8% degree of hydrolysis and a flamboyant gum with a substitution degree of 0.91 were obtained. The greatest interaction between both biopolymers was obtained using a 5:1 ratio of SHM to pH 4 according to the FIT value. Conclusions. The mixed hydrocolloid systems prepared with extensive hydrolyzate of the hard to cook P. vulgaris and modified flamboyant gum proteins showed an increase in antioxidant activity, compared to the hydrolyzate depending on the oxidation mechanism, as well as the pH conditions used and interaction between both component(AU)

BACKGROUND: The evidence of early mobilization after stroke is conflicting, and the recovery period is an important concern. OBJECTIVE: To analyse the functionality, quality of life and disability at 90 days and 1 year post-stroke of patients who received a Very Early Mobilization Protocol. METHODS: Prospective cohort study in a tertiary stroke unit. Consecutive patients aged≥18 years and without prior significant disability, who presented motor deficit after acute stroke, were included. A symmetry test was performed to compare the changes in the main variables: Barthel Index (BI), Functional Ambulation Category (FAC), modified Rankin Scale (mRS) and EuroQol five-dimensions three-level (EQ-5D-3L) between 90 days and 1 year post-stroke. RESULTS: A total of 123 patients were recruited. The BI reflected an improvement at 1 year in transfer to chair/bed in 25.8%(pâ<â0.01) of patients and in toilet use in 25.8%(pâ=â0.02). The FAC showed an improvement at 1 year in 44.4%(pâ<â0.01) of patients and the mRS in 19.1%(pâ=â0.01). The usual activities dimension of the EQ-5D-3L showed a clinically relevant improvement after 1 year in 15.9%(pâ=â0.23) of patients. CONCLUSIONS: A significant percentage of patients show improvements in some functional areas and in disability between 90 days and 1 year post-stroke.

Literature linking aggressive behavior across internalizing and externalizing disorders support the co-occurrence of aggression and various mental health diagnoses. However, research has yet to examine relationships between aggression and dimensional psychopathology models that cut across diagnostic boundaries (e.g., internalizing, externalizing composites) and capture shared liability across common disorders. The role of gender has also been largely ignored in prior work, despite evidence that men and women manifest psychopathology differently. The present study examined cross-sectional and longitudinal relationships between psychopathology composites (i.e., Internalizing, Externalizing) and different manifestations of physical aggression (i.e., aggressive traits, general violence, physical intimate partner violence, and self-directed aggression), as well as moderation by gender. Internalizing (INT) and Externalizing (EXT) lifetime symptoms and various physically aggressive behaviors were assessed at baseline and at 6 months and 1 year follow up in a sample of 319 adults with violence and/or substance use histories. Cross-sectional results showed that INT was associated with all forms of aggression, and women showed stronger relationships between INT and both physical intimate partner violence (IPV) and self-directed aggression. EXT was specifically linked to general violence, and a stronger relationship between EXT and self-directed aggression emerged in men compared to women. Longitudinal relationships were mostly small and nonsignificant. Results support the co-occurrence of aggression with distinct forms of psychopathology, as well as gender-dependent relationships, but do not support the predictive validity of symptom composites in aggression risk. Findings implicate the need for aggression interventions tailored within gender.

Objectives: Left atrial disease is an independent risk factor for ischemic stroke and can be used to predict atrial fibrillation (AF). We examine whether left atrial enlargement (LAE) could predict stroke recurrence in patients with embolic stroke of undetermined source (ESUS). Materials and methods: Sixty-four patients with a confirmed diagnosis of ESUS were followed for a median of 22 months. Clinical data and echocardiogram findings were recorded. The echocardiogram interpretation was performed centrally and blindly. The Brown ESUS - AF score was used to categorize patients into high (human resource planning [HRP]: score > 2) and low-risk patients (non-HRP score 0-1). Stroke recurrence was the primary outcome. Results: The median age was 62 years (range: 22-85 years); and 33 (51.6%) were men. The median initial NIHSS score was three points (range: 0-27). Twelve (18.8%) patients were categorized as HRP. We found a significant tendency toward recurrence among HRP versus non-HRP patients. Three (25%) HRP versus 2 (3.8%) non-HRP experienced recurrence (OR: 8.3 95% CI 1.2-57; p=0.042); this association was related to severe atrial dilatation (OR: 14.5 95% CI 0.78-277, p = 0.02) and age > 75 years (OR: 12.7 95% CI 1.7-92.2, p = 0.03). We found no differences in recurrence in a univariate analysis. Conclusions: Patients with severe LAE who are 75 years old or older have a significant tendency to experience stroke recurrence.

La escala de Brown ESUS AF fue utilizada para categorizar a los pacientes en riesgo alto (HRP puntaje > 2) y bajo riesgo (no-HRP: puntaje 0-1). El descenlace primario fue recurrencia de infarto cerebral. Resultados: Mediana de edad fue de 62 años (rango: 22-85 años); 33 (51.6%) fueron hombres. La mediana inicial de la escala de NIHSS fue de 3 putnos (rango de 0 a 27). 12 (18.8%) pacientes fueron de alto riesgo (HRP) y 52 (81.3%) de bajo riesgo (non- HRP). El grupo HRP mostró tendencia significatica hacia mayor recurrencia. Tres (25%) HRP versus 2 (3.8%) no-HRP experimentaron recurrencia (OR: 8.3 IC 95% 1.2-57; p = 0.042); esta asociación se relacionó con dilatación auricular severa (OR: 14.5 IC 95% 0.78-277, p = 0.02) y edad > 75 años (OR: 12.7 IC 95% 1.7-92.2, p = 0.03). En el análisis multivarioado, no encontramos significativas. Conclusiones: El crecimiento auricular izquierdo severo y la edad mayor de 75 años mostraron tendencia significativa a recurrencia de infarto cerebral.

BACKGROUND: OSA conveys worse clinical outcomes in patients with coronary artery disease. The STOP-BANG score is a simple tool that evaluates the risk of OSA and can be added to the large number of clinical variables and scores that are obtained during the management of patients with myocardial infarction (MI). Currently, machine learning (ML) is able to select and integrate numerous variables to optimize prediction tasks. RESEARCH QUESTION: Can the integration of STOP-BANG score with clinical data and scores through ML better identify patients who experienced an in-hospital cardiovascular event after acute MI? STUDY DESIGN AND METHODS: This is a prospective observational cohort study of 124 patients with acute MI of whom the STOP-BANG score classified 34 as low (27.4%), 30 as intermediate (24.2%), and 60 as high (48.4%) OSA-risk patients who were followed during hospitalization. ML implemented feature selection and integration across 47 variables (including STOP-BANG score, Killip class, GRACE score, and left ventricular ejection fraction) to identify those patients who experienced an in-hospital cardiovascular event (ie, death, ventricular arrhythmias, atrial fibrillation, recurrent angina, reinfarction, stroke, worsening heart failure, or cardiogenic shock) after definitive MI treatment. Receiver operating characteristic curves were used to compare ML performance against STOP-BANG score, Killip class, GRACE score, and left ventricular ejection fraction, independently. RESULTS: There were an increasing proportion of cardiovascular events across the low, intermediate, and high OSA risk groups (P = .005). ML selected 7 accessible variables (ie, Killip class, leukocytes, GRACE score, c reactive protein, oxygen saturation, STOP-BANG score, and N-terminal prohormone of B-type natriuretic peptide); their integration outperformed all comparators (area under the curve, 0.83 [95% CI, 0.74-0.90]; P < .01). INTERPRETATION: The integration of the STOP-BANG score into clinical evaluation (considering Killip class, GRACE score, and simple laboratory values) of subjects who were admitted for an acute MI because of ML can significantly optimize the identification of patients who will experience an in-hospital cardiovascular event.
