Congenital Juvenile Xanthogranuloma in the Perioral Region: A Case Image.

Juvenile xanthogranuloma (JXG) is the most common form of non-Langerhans cell histiocytosis in childhood. It often presents with cutaneous involvement and exhibits a predilection for the head and neck region. This article illustrates a case of congenital JXG in a 5-month-old boy, characterized by a solitary, well-circumscribed nodule above the left upper lip. Histopathologically, the lesion exhibited histiocytes with eosinophilic cytoplasm and Touton giant cells. Immunohistochemistry revealed histiocytes positive for CD68 and Factor XIIIa, while negative for S-100 protein. Clinicians should become familiar with the broad clinical spectrum of cutaneous JXG, particularly its congenital presentation, in order to ensure timely and accurate management.

Tumor and Peritoneum-Associated Macrophage Gene Signature as a Novel Molecular Biomarker in Gastric Cancer.

A spectrum of immune states resulting from tumor resident macrophages and T-lymphocytes in the solid tumor microenvironment correlates with patient outcomes. We hypothesized that in gastric cancer (GC), macrophages in a polarized immunosuppressive transcriptional state would be prognostic of poor survival. We derived transcriptomic signatures for M2 (M2TS, MRC1; MS4A4A; CD36; CCL13; CCL18; CCL23; SLC38A6; FGL2; FN1; MAF) and M1 (M1TS, CCR7; IL2RA; CXCL11; CCL19; CXCL10; PLA1A; PTX3) macrophages, and cytolytic T-lymphocytes (CTLTS, GZMA; GZMB; GZMH; GZMM; PRF1). Primary GC in a TCGA stomach cancer dataset was evaluated for signature expressions, and a log-rank test determined overall survival (OS) and the disease-free interval (DFI). In 341 TCGA GC entries, high M2TS expression was associated with histological types and later stages. Low M2TS expression was associated with significantly better 5-year OS and DFI. We validated M2TS in prospectively collected peritoneal fluid of a GC patient cohort (n = 28). Single-cell RNA sequencing was used for signature expression in CD68+CD163+ cells and the log-rank test compared OS. GC patients with high M2TS in CD68+CD163+ cells in their peritoneal fluid had significantly worse OS than those with low expression. Multivariate analyses confirmed M2TS was significantly and independently associated with survival. As an independent predictor of poor survival, M2TS may be prognostic in primary tumors and peritoneal fluid of GC patients.

A Case Study of the Development of a Valid and Pragmatic Implementation Science Measure: The Barriers and Facilitators in Implementation of Task-Sharing Mental Health Interventions (BeFITS-MH) Measure.

Background: Few implementation science (IS) measures have been evaluated for validity, reliability and utility - the latter referring to whether a measure captures meaningful aspects of implementation contexts. In this case study, we describe the process of developing an IS measure that aims to assess Barriers and Facilitators in Implementation of Task-Sharing in Mental Health services (BeFITS-MH), and the procedures we implemented to enhance its utility. Methods: We summarize conceptual and empirical work that informed the development of the BeFITS-MH measure, including a description of the Delphi process, detailed translation and local adaptation procedures, and concurrent pilot testing. As validity and reliability are key aspects of measure development, we also report on our process of assessing the measure's construct validity and utility for the implementation outcomes of acceptability, appropriateness, and feasibility. Results: Continuous stakeholder involvement and concurrent pilot testing resulted in several adaptations of the BeFITS-MH measure's structure, scaling, and format to enhance contextual relevance and utility. Adaptations of broad terms such as "program," "provider type," and "type of service" were necessary due to the heterogeneous nature of interventions, type of task-sharing providers employed, and clients served across the three global sites. Item selection benefited from the iterative process, enabling identification of relevance of key aspects of identified barriers and facilitators, and what aspects were common across sites. Program implementers' conceptions of utility regarding the measure's acceptability, appropriateness, and feasibility were seen to cluster across several common categories. Conclusions: This case study provides a rigorous, multi-step process for developing a pragmatic IS measure. The process and lessons learned will aid in the teaching, practice and research of IS measurement development. The importance of including experiences and knowledge from different types of stakeholders in different global settings was reinforced and resulted in a more globally useful measure while allowing for locally-relevant adaptation. To increase the relevance of the measure it is important to target actionable domains that predict markers of utility (e.g., successful uptake) per program implementers' preferences. With this case study, we provide a detailed roadmap for others seeking to develop and validate IS measures that maximize local utility and impact.

Influencia de los estilos de vida saludables en el compromiso hacia los estudios y el rendimiento académico en los adolescentes / Influence of healthy lifestyles on commitment to studies and academic performance in adolescents

Objetivo: El objetivo del estudio fue examinar la relación entre el estilo de vida saludable y el compromiso hacia los estudios y el rendimiento académico. Método: Se trata de un estudio transversal y correlacional en el que participaron 359 adolescentes, 162 chicos y 197 chicas, de entre 13 y 20 años de edad. Se analizó el nivel de AF, el tiempo sedentario de pantalla, la duración del sueño, la adherencia a la dieta Mediterránea y el compromiso hacia los estudios a través de cuestionarios previamente validados, mientras que el rendimiento académico se calculó como una nota media de las calificaciones de los adolescentes en las asignaturas de lengua, inglés, matemáticas y educación física. Resultados: Aquellos alumnos con mayores niveles de AF y una mayor adherencia a dieta mediterránea presentaron mayor compromiso hacia los estudios, y aquellos que cumplían con el tiempo de pantalla estipulado y mostraron adherencia por el patrón mediterráneo obtuvieron mejores resultados académicos. No se encontraron resultados significativos para el tiempo de pantalla y el tiempo sueño con el compromiso hacia los estudios, ni tampoco para la AF y el tiempo de sueño con el rendimiento académico. Conclusión: Nuestros resultados resaltan la importancia de promover la AF y la adherencia a la dieta mediterránea para conseguir un mayor compromiso hacia los estudios. También se ha comprobado que los adolescentes que consumen menos tiempo de pantalla y tienen una mayor adherencia al patrón mediterráneo mostraron un mayor rendimiento académico. (AU)

Effect of coaches' interpersonal style on young athletes' individual resilience and team adherence intention: a season-long investigation.

BACKGROUND: In the sports context, coaches must be able to improve their players physically, psychologically, and socially. Hence, a fundamental part of this process is the athlete's individual resilience (IR). METHODS: Three hundred and fifteen youth team-sport players (boys: n = 283; Mage = 16.02, SD = 0.56; and girls: n = 32; Mage = 15.92, SD = 0.62) completed the measures of coach's interpersonal style, individual resilience, perceived performance, and team adherence intention (intention to remain on the same team the following year) twice (Time 1: mid-season; Time 2: end-season). Structural equation modeling was used to test the relationships between variables. RESULTS: The results showed that coach support was positively related to IR (p < 0.001) and, in turn, IR to individual (p < 0.01) and team performance (p < 0.05) at Time 1, and to individual performance (p < 0.001) and team adherence intention at Time 2 (p < 0.01). In addition, team performance at Time 2 was positively related to team adherence intention (p < 0.001). Finally, a mediating effect of IR was observed between interpersonal coaching style, individual and team performance, and team adherence intention. CONCLUSIONS: These results show the importance of a supportive interpersonal coaching style to foster athletes' levels of resilience, which could have positive consequences in performance (individual and team) and team adherence intention.

A super-enhancer-regulated RNA-binding protein cascade drives pancreatic cancer.

Pancreatic ductal adenocarcinoma (PDAC) is a lethal malignancy in need of new therapeutic options. Using unbiased analyses of super-enhancers (SEs) as sentinels of core genes involved in cell-specific function, here we uncover a druggable SE-mediated RNA-binding protein (RBP) cascade that supports PDAC growth through enhanced mRNA translation. This cascade is driven by a SE associated with the RBP heterogeneous nuclear ribonucleoprotein F, which stabilizes protein arginine methyltransferase 1 (PRMT1) to, in turn, control the translational mediator ubiquitin-associated protein 2-like. All three of these genes and the regulatory SE are essential for PDAC growth and coordinately regulated by the Myc oncogene. In line with this, modulation of the RBP network by PRMT1 inhibition reveals a unique vulnerability in Myc-high PDAC patient organoids and markedly reduces tumor growth in male mice. Our study highlights a functional link between epigenetic regulation and mRNA translation and identifies components that comprise unexpected therapeutic targets for PDAC.

Adverse sequelae of the COVID -19 pandemic on mental health services in Chile.

Objective: This study seeks to describe the adverse effects of the COVID-19 pandemic on mental health services in Chile. Methods: This study is part of ongoing multicountry research known as the Mental Health Care - Adverse Sequelae of COVID-19 study (or the MASC study) that includes seven countries. Chile is the only one in Latin America. This study used a convergent mixed methods design. The quantitative component analyzed data about public mental health care collected between January 2019 and December 2021 from the open-access database at the Ministry of Health. The qualitative component analyzed data collected from focus groups of experts that included professionals in charge of mental health services, policy-makers, service users and caregivers. Finally, the data synthesis was performed by triangulation of both components. Results: By April 2020, mental health service provision had been reduced by 88% in primary care; moreover, secondary and tertiary levels had also reduced their mental health activities by, respectively, 66.3% and 71.3% of pre-COVID levels. Negative sequelae were described at the health systems level, and full recovery had not been achieved by the end of 2021. The pandemic affected the essential characteristics of community-based mental health services, with adverse impacts on the continuity and quality of care, reduced psychosocial and community support, and negative effects on health workers' mental health. Digital solutions were widely implemented to enable remote care, but challenges included the availability of equipment, its quality and the digital divide. Conclusions: The COVID-19 pandemic has had significant and enduring adverse effects on mental health care. Lessons learned can inform recommendations for good practices for the ongoing and future pandemics and health crises, and highlight the importance of prioritizing the strengthening of mental health services in response to emergencies.

Intervention Programme Based on Self-Determination Theory to Promote Extracurricular Physical Activity through Physical Education in Primary School: A Study Protocol.

Low levels of physical activity (PA) are a concern among students, producing negative physical, health and mental consequences. This study aims to present a protocol intervention in physical education (PE) based on self-determination theory (SDT) to enhance students' motivation towards performing PA and increasing their PA levels in their leisure time. This protocol is a convenience study with two allocation arms (intervention group versus control group). SDT-based motivational strategies will be carried out and co-created with PE teachers to increase motivation and out-of-school PA levels. Data collection will be conducted three times: before the intervention, after the intervention (four months after baseline) and at the end of the intervention (retention measurement, seven months after baseline). The measures will assess perceived teacher support for PA, motivation towards PA, intention to be physically active, PA levels, engagement in PE and academic performance. Overall, this intervention programme is expected to increase students' autonomous motivation for PA and their PA levels in their free time. This intervention might encourage teachers to establish strategies and resources to increase their students' adaptive outcomes.

¿Influye el liderazgo del entrenador sobre la resiliencia de equipo? Efecto mediador de los conflictos intragrupo y la cohesión grupal / Does coach leadership influence team resilience? Mediating effect of intra-group conflict and group cohesion

Resumen Introducción/objetivo: El presente estudio tiene como objetivo examinar la rela ción entre el liderazgo transformacional del entrenador y las características de resiliencia y la vulnerabilidad bajo presión, así como analizar si los factores del conflicto intragrupo (social y tarea) y de la cohesión grupal (social y tarea), pudieran mediar la relación entre dichas variables. Método: A través de un diseño longitudinal, se incluyó a un total de 301 depor tistas inscritos en los JUDEX, pertenecientes a 34 equipos de fútbol y voleibol, con edades comprendidas entre 13 y 18 años (M = 15.72; DT = 1.33). Resultados: Los resultados mostraron una relación positiva entre el liderazgo transformacional del entrenador y las características de resiliencia, y una asociación negativa respecto a la vulnerabilidad bajo presión. Además, el conflicto intragrupo (social y tarea) actuó como mediador entre la relación del liderazgo trans formacional del entrenador y la resiliencia de equipo. En cuanto al papel mediador de la cohe sión grupal, solo la cohesión tarea actuó como mediadora entre el liderazgo transformacional del entrenador y la resiliencia de equipo. Conclusiones: La presente investigación muestra la importancia del liderazgo del entrenador para mejorar la resiliencia del equipo en categorías de formación, y la influencia positiva que tiene la reducción de los conflictos intragrupo y el aumento de la cohesión tarea durante la temporada.

Abstract Introduction/objective: The present study aimed to examine the relationship be tween transformational coach leadership with the characteristics of resilience and vulnerability under pressure, as well as to analyze whether the factors of intra-group conflict (social and task) and group cohesion (social and task) could mediate the relationship between these variables. Method: Through a longitudinal design, a total of 301 athletes enrolled in the JUDEX, belong ing to 34 soccer and volleyball teams, and aged between 13 and 18 years (M = 15.72; SD = 1.33). Results: The results showed a positive relationship between transformational leadership of the coach and resilience characteristics, and a negative association with respect to vulnerability under pressure. In addition, intra-group conflict (social and task) acted as mediators between the relationship between transformational coach leadership and team resilience. Regarding the mediating role of group cohesion, only task cohesion acted as a mediator between trans formational coach leadership and team resilience. Conclusions: This research draws as main conclusion the importance of the coach's leadership to improve team resilience in youth cate gories, and the positive influence of the reduction of intragroup conflicts and the increase of task cohesion during the season.

The Predictive Role of Perceived Autonomy Support in Elementary School Children Physical Activity.

The present article aimed to test a predictive model based on children's perception of autonomy support exercised by their physical education teachers in establishing a state of high motivational quality, which in turn leads to greater intention and physical activity. Participants were 502 elementary school students aged 9 to 11 years (52.59% males (9.47 ± 0.53 years old) and 47.41% females (9.54 ± 0.53 years old)), who completed a self-reported questionnaire of perceived autonomy support from physical education teachers, self-determination, intention to be physically active, and physical activity. Results showed that perceived autonomy support was positively related to autonomous motivation, which in turn was associated with intention and physical activity. In addition, the model did not present variations with respect to gender and confirmed the indirect effects of autonomous motivation on intention and practice of physical activity. Finally, we conclude on the importance of an adequate perception of autonomy support in students by their teachers for the establishment of an appropriate motivational state that could promote greater intention and physical activity. Thus, the motivational state acquired in physical education classes can be translated into intention and practice of physical activity in different contexts of students' daily lives.

An Exosome-based Transcriptomic Signature for Noninvasive, Early Detection of Patients With Pancreatic Ductal Adenocarcinoma: A Multicenter Cohort Study.

BACKGROUND & AIMS: Pancreatic ductal adenocarcinoma (PDAC) incidence is rising worldwide, and most patients present with an unresectable disease at initial diagnosis. Measurement of carbohydrate antigen 19-9 (CA19-9) levels lacks adequate sensitivity and specificity for early detection; hence, there is an unmet need to develop alternate molecular diagnostic biomarkers for PDAC. Emerging evidence suggests that tumor-derived exosomal cargo, particularly micro RNAs (miRNAs), offer an attractive platform for the development of cancer-specific biomarkers. Herein, genomewide profiling in blood specimens was performed to develop an exosome-based transcriptomic signature for noninvasive and early detection of PDAC. METHODS: Small RNA sequencing was undertaken in a cohort of 44 patients with an early-stage PDAC and 57 nondisease controls. Using machine-learning algorithms, a panel of cell-free (cf) and exosomal (exo) miRNAs were prioritized that discriminated patients with PDAC from control subjects. Subsequently, the performance of the biomarkers was trained and validated in independent cohorts (n = 191) using quantitative reverse transcription polymerase chain reaction (qRT-PCR) assays. RESULTS: The sequencing analysis initially identified a panel of 30 overexpressed miRNAs in PDAC. Subsequently using qRT-PCR assays, the panel was reduced to 13 markers (5 cf- and 8 exo-miRNAs), which successfully identified patients with all stages of PDAC (area under the curve [AUC] = 0.98 training cohort; AUC = 0.93 validation cohort); but more importantly, was equally robust for the identification of early-stage PDAC (stages I and II; AUC = 0.93). Furthermore, this transcriptomic signature successfully identified CA19-9 negative cases (<37 U/mL; AUC = 0.96), when analyzed in combination with CA19-9 levels, significantly improved the overall diagnostic accuracy (AUC = 0.99 vs AUC = 0.86 for CA19-9 alone). CONCLUSIONS: In this study, an exosome-based liquid biopsy signature for the noninvasive and robust detection of patients with PDAC was developed.

Bioactive Metabolites from the Endophytic Fungus Aspergillus sp. SPH2.

In the current study, an ethyl acetate extract from the endophytic fungus Aspergillus sp. SPH2 isolated from the stem parts of the endemic plant Bethencourtia palmensis was screened for its biocontrol properties against plant pathogens (Fusarium moniliforme, Alternaria alternata, and Botrytis cinerea), insect pests (Spodoptera littoralis, Myzus persicae, Rhopalosiphum padi), plant parasites (Meloidogyne javanica), and ticks (Hyalomma lusitanicum). SPH2 gave extracts with strong fungicidal and ixodicidal effects at different fermentation times. The bioguided isolation of these extracts gave compounds 1-3. Mellein (1) showed strong ixodicidal effects and was also fungicidal. This is the first report on the ixodicidal effects of 1. Neoaspergillic acid (2) showed potent antifungal effects. Compound 2 appeared during the exponential phase of the fungal growth while neohydroxyaspergillic acid (3) appeared during the stationary phase, suggesting that 2 is the biosynthetic precursor of 3. The mycotoxin ochratoxin A was not detected under the fermentation conditions used in this work. Therefore, SPH2 could be a potential biotechnological tool for the production of ixodicidal extracts rich in mellein.

Standardization and Chemical Characterization of Intravenous Therapy in Adult Patients: A Step Further in Medication Safety.

BACKGROUND: Intravenous drug administration is associated with potential complications, such as phlebitis. The physiochemical characteristics of the infusate play a very important role in some of these problems. AIM: The aim of this study was to standardize the dilutions of intravenous drugs most commonly used in hospitalized adult patients and to characterize their pH, osmolarity and cytotoxic nature to better guide the selection of the most appropriate vascular access. METHODS: The project was conducted in three phases: (i) standardization of intravenous therapy, which was conducted using a modified double-round Delphi method; (ii) characterization of the dilutions agreed on in the previous phase by means of determining the osmolarity and pH of each of the agreed concentrations, and recording the vesicant nature based on the information in literature; and (iii) algorithm proposal for selecting the most appropriate vascular access, taking into account the information gathered in the previous phases. RESULTS: In total, 112 drugs were standardized and 307 different admixtures were assessed for pH, osmolarity and vesicant nature. Of these, 123 admixtures (40%), had osmolarity values >600 mOsm/L, pH < 4 or > 9, or were classified as vesicants. In these cases, selection of the most suitable route of infusion and vascular access device is crucial to minimize the risk of phlebitis-type complications. CONCLUSIONS: Increasing safety of intravenous therapy should be a priority in the healthcare settings. Knowing the characteristics of drugs to assess the risk involved in their administration related to their physicochemical nature may be useful to guide decision making regarding the most appropriate vascular access and devices.

Acoustic analysis of cry in with cleft palate patients / Análisis acústico del llanto en pacientes con hendidura palatina

INTRODUCTION: Crying in newborns and infants is a functional expression of biological interest. Through, acoustic analysis of crying, results of a primary palatoplasty can be evaluated in patients with cleft palate before development of speech, is objective, non-invasive, quick and simple tool for vocal exploration. The objective is to determine Fundamental Frequency (F0) of spontaneous crying in patients with pre and postoperative cleft palate, and compare with healthy control group through PRAAT software, in period between 2017 and 2019. MATERIALS AND METHODS: A sample of 16 patients from 18 to 30 months of age with cleft palate was obtained. Recordings were made of spontaneous pre and postoperative crying, and healthy control group; later were digitally recorded, and analyzed through PRAAT Software. RESULTS: 56.2 % were female and 43.7 % were male, witn average age of 25.8 months. Primary palatoplasty was performed using Veau Wadrill technique and Furlow technique. F0 of crying was Pitch average value 349.125 Hz preoperative and Pitch average postoperative control 369.775 Hz. More acute crying emissions were observed in postoperative period (p < 0.000), presenting similar values with control group (p < 0.000). CONCLUSION: Fundamental frequency (F0) was determined in patients with cleft palate, they presented a significant increase of 15,5 % in postoperative controls of primary palatoplasty, similar to healthy control group

INTRODUCCIÓN: El llanto de los recién nacidos y lactantes es una expresión funcional de interés biológico, por lo cual, a través del análisis acústico del llanto se pueden evaluar los resultados de una palatoplastia primaria en pacientes con hendidura palatina antes del desarrollo del habla, por ser una herramienta objetiva, no invasiva, rápida y sencilla de exploración vocal. El objetivo es determinar la frecuencia fundamental (F0) del llanto espontáneo en los pacientes con hendidura palatina pre y posoperatorio, y comparar con el grupo control sano a través del software PRAAT, en el periodo entre el año 2017 y 2019. MATERIALES Y MÉTODOS: Se obtuvo una muestra de 16 pacientes de 18 a 30 meses de edad con hendidura palatina. Se realizaron grabaciones del llanto espontáneo pre y posoperatorio, y del grupo control sano; posteriormente fueron grabadas digitalmente, y analizadas a través del software PRAAT. RESULTADOS: El 56,2 % fue del género femenino y el 43,7 % del género masculino, con edad promedio de 25,8 meses. Se realizó palatoplastia primaria mediante técnica de Veau Wadrill y técnica Furlow. La F0 del llanto fue de valor promedio Pitch 349.125 Hz preoperatorio y un control posoperatorio promedio Pitch 369.775 Hz. Se evidenció emisiones del llanto más agudas en el posoperatorio (p < 0,000), presentando valores similares con el grupo control (p < 0,000). CONCLUSIÓN: Se determinó frecuencia fundamental (F0) en los pacientes con hendidura palatina, presentaron un incremento significativo de 15,5 % en los controles posoperatorio de palatoplastia primaria, similares al grupo control sano

Double neurophysiological certification of the filum terminale during sectioning surgery in pediatric population.

BACKGROUND: Surgery of thickened-fibrolipoma filum terminale (FT) is performed routinely and without conflict but is not a risk-free surgical procedure. Intraoperative neurophysiological monitoring with mapping techniques can help to certify the FT before sectioning. However, a tailored surgical approach to cauda equina and a low threshold of surrounding nerve roots can confuse the final surgical decision. The aim is to demonstrate the usefulness of this double methodology for FT certification. METHODS: A prospective study collected and reviewed retrospectively, from 2015 to 2018, 40 patients undergoing an FT surgery section were included in the study. After opening the dura mater and under the microscope, the cauda equina mapping is performed and the recording of muscles of the lower limbs and the external anal sphincter. In addition, a high-intensity stimulation of constant current of an isolated FT for a short period of time and in a dry surgical field, obtaining a bilateral-polyradicular-symmetrical response of cauda equina nerve roots. RESULTS: Traditional motor mapping identified FT in 65% (26/40) of patients. Although, 35% (14/40) of the patients still have low-intensity stimuli response (<1 mA) of a muscle, especially anal sphincter. When this happens, the optimization of the dissection around FT is performed. After that, 25% (10/40) of the patients still having a muscle response in spite of seem isolated FT. Increasing the stimulation intensity up to 20 mA evoked a cauda equina response in all cases. No postoperative neurological impairment was observed in this series. CONCLUSION: This proposed methodology accurately confirms the FT so that it can be safely found and cut. The Double Neurophysiological Certification improves the gap of the traditional mapping techniques of cauda equina and can be used in a variety of more complex surgeries in this area.
