Exploring relapse through a network analysis of residual depression and anxiety symptoms after cognitive behavioural therapy : a proof-of-concept study

Objective: Many patients relapse within one year of completing effective cognitive behavioural therapy (CBT) for depression and anxiety. Residual symptoms at treatment completion have been demonstrated to predict relapse, and so this study used network analyses to improve specificity regarding which residual anxiety and depression symptoms predict relapse. Method: A cohort study identified relapse cases following low- and high-intensity CBT in a stepped care psychological therapy service. The sample included N=867 ‘recovered’ treatment completers that attended a six-month follow-up review. At follow-up, N=93 patients had relapsed and N=774 remained in-remission. Networks of final treatment session depression (PHQ-9) and anxiety (GAD-7) symptoms were estimated for both sub-groups. Results: Qualitatively similar symptom networks were found. Difficulty concentrating was a highly central symptom in the relapse network, whilst of only average centrality in the remission network. In contrast, trouble relaxing was highly central in the remission network, whilst of only average centrality in the relapse network. Discussion: Identification of central residual symptoms holds promise in improving the specificity of prognostic models and the design of evidence-based relapse prevention strategies. The small sample of relapse cases limits this study’s ability to draw firm conclusions

European Spallation Source as a searching tool for an ultralight scalar field

Dark matter (DM) nature is one of the major issues in physics. The search for a DM candidate has motivated the known proposal of an ultralight scalar field (ULSF). We explore the possibility to search for this ULSF at the upcoming European Spallation Source neutrino Super-Beam experiment. We have considered the recent study case in which there could be an interaction between the ULSF and active neutrinos. We have found that in this future experimental setup, the sensitivity is competitive with other neutrino physics experiments. We show the expected future sensitivity for the main parameter modeling the interaction between ULSF and neutrinos.Comment: 27 pages, 3 figures. Section added, extended discussion. To appear in PR

Autolytic changes involving proteolytic enzymes on Atlantic salmon (Salmo salar) preserved by hyperbaric storage

he effect of hyperbaric storage (HS, 50–75 MPa at 10–37 °C) on proteolytic enzymes and muscle proteins of Atlantic salmon (Salmo salar) was assessed and compared to atmospheric pressure (AP, 0.1 MPa) at the same storage temperature and refrigeration (AP, 5 °C). Generally, activities of acid phosphatase, cathepsin B and D, and calpains decreased when compared to fresh salmon, with a more’ pronounced effect of storage temperature of 37 °C in HS/AP samples. However, activity recovery was observed for some enzymes, as the case of cathepsins B and D, and calpains, whose showed an increase of residual activity for samples stored at 60 MPa/10 °C and 75 MPa/25 °C after 50 and 25 d, respectively. A pronounced increase of myofibrillar fragmentation index (MFI) was observed at 75 MPa (25/37 °C) after 10 d (3.2-/4.3-fold, respectively). Otherwise, at 60 MPa/10 °C, a decrease of MFI values was observed after 50 d of storage. For sarcoplasmic proteins, no effect was observed at 60 MPa/10 °C during 30 d of storage, with a slight increase after 50 d. At 75 MPa/25 °C, a decrease of sarcoplasmic proteins content (46%) was obtained after 10 d with no further changes during the 25 d of storage.publishe

PROSPECTIVA Y CAMBIO EN LAS INSTITUCIONES DE EDUCACIÓN SUPERIOR Y SUS RELACIONES CON LA SOCIEDAD UNA MIRADA DE LOS ESTUDIANTES AL MODELO DE INNOVACIÓN CURRICULAR DE LA UAEM

Para comprender el tipo de relación que los estudiantes del área de educación y humanidades de la UAEM, construyen respecto al MIIC y a la formación profesional, resulta de fundamental importancia ubicar la posición desde la cual elaboran un conjunto de nuevas relaciones al insertarse en la red simbólica propuesta por el orden institucional. Para abordar el tema de estudio se formularon las siguientes preguntas de investigación: ¿Qué ordenamientos simbólicos mostraban los discursos sobre la formación profesional que fueron consideradas por los estudiantes en su búsqueda de plenitud, es decir, de ser psicólogos, trabajadores sociales, historiadores, filósofos, actores, bibliotecólogos, licenciados en Letras Latinoamericanas y Educación? ¿Desde qué ordenamientos simbólicos construían las imágenes con las que deseaban identificarse? Ahora bien, el supuesto general que funcionó como punto de arranque de esta investigación, el considerar que el discurso del MIIC (la versión que se construyó institucionalmente) no hegemonizó la configuración identitaria de los estudiantes del Área de Educación y Humanidades de la UAEM. Para dar seguimiento a este supuesto, se realizó una reconstrucción analítica del proceso identificatorio desde una lógica discursiva de razonamiento, recuperada del análisis político de discurso. El texto se organiza en dos apartados, en el primero se aborda la propuesta formulada por Fuentes (1999, 2008), para dar cuenta de los juegos de significación en los que se desarrollan los procesos de identificación de los sujetos educativos desde tres líneas de análisis: lo político (como articulación hegemónica), lo sociológico (como armada al interior de entramados sociales) y lo psicoanalítico (como apuntalada fantasmáticamente). En el segundo apartado se ofrece una interpretación tridimensional del proceso de constitución de la identidad de los estudiantes del área de educación y humanidades. Es decir, el análisis propuesto no sólo se circunscribe al plano teórico-conceptual, sino que propone como estrategia metodológica una articulación permanente entre éste y el referente empírico. Este último por la necesidad de ubicar los lugares institucionales desde los que los estudiantes de los programas analizados armaron una serie de representaciones en relación al orden escolar y al proceso que vivieron al interior del mismo. Se aplicó un cuestionario tipo encuesta a una población de 80 alumnos del octavo periodo del área de educación y humanidades (estudiantes de las licenciaturas de Artes Teatrales, Ciencias de la Información Documental, Filosofía, Letras Latinoamericanas, Historia, Psicología, Trabajo Social y Educación de la UAEM); cinco estudiantes por generación y 10 por programa educativo de las generaciones 2006-2011 y 2007-2012. Información con la cual se pretende dar cuenta del espectro de posibilidades sobre el proceso identificatorio de los estudiantes del Área de Educación y Humanidades de la UAEM

Shelf-life extension of watermelon juice preserved by hyperbaric storage at room temperature compared to refrigeration

This work reports Hyperbaric Storage (HS) preservation of raw watermelon juice at variable/uncontrolled room temperature (RT,z21 C) for 7 days at 100 MPa and compared it with refrigeration (RF). At the end of storage, there was an increase in microbial counts (total aerobic mesophiles, psychrophiles, and yeasts and moulds) to above 6 log10 CFU/mL for samples stored at atmospheric pressure (RF and RT), while juice stored under HS/RT showed maximum values of about 2 log10 CFU/mL for total aerobic mesophiles/ psychrophiles and below the detection limit for yeasts and moulds. HS/RT juice showed also physicochemical parameters at levels similar to the initial juice. Thus, HS/RT can not only be used to preserve foods with no refrigeration energetic costs (since it does not require temperature control), but additionally, has also a great potential to extend the shelf-life of food products, compared to RF. This is the first case in the literature showing this additional potential/advantage of HS/RT

High pressure and thermal pasteurization effects on sweet cherry juice microbiological stability and physicochemical properties

This study evaluated high pressure processing (P1 – 400 MPa/5 min; P2 – 550 MPa/2 min) and thermal pasteurization (TP – 70°C/30 s) effects on sweet cherry juice’s microbiological and physicochemical parameters, during four weeks of refrigerated storage. All treatments reduced the microbiological load to undetectable levels not affecting total soluble solids and titratable acidity. The pH increased with all treatments, however, it decreased during storage. Phenols were differently affected: TP increased them by 6%, P1 had no effect while P2 decreased them by 11%. During storage, phenols in control and TP samples decreased by 26% and 20%, P1 samples decreased them by 11% whereas P2 showed no variation. TP had no effect on anthocyanins, while pressure treatments increased them by 8%. Anthocyanins decreased during storage, particularly in the control and P1 (decreasing 41%). All treatments had no effect on antioxidant activity until the 14th day, thereafter high pressure processing samples showed the highest antioxidant activity

Agroecological practices to support tropical livestock farming systems: a Caribbean and Latin American perspective

With global climate changes currently occurring, and particularly given the severe energy and food shortages occurring throughout tropical regions, agroecological (AE) systems are drawing renewed attention as an efficient alternative to intensive models of production, particularly unsuitable in regions of the world such as the Caribbean or Latin America. There is a pressing need to focus on livestock farming systems (LFS) and characterize their potential contributions to global sustainability. A multidisciplinary approach is needed to address these multiple and complex problems. Traditionally, LFS have shown their sustainability high potential. The purpose of this work is to highlight solutions to minimize inputs, by describing some success and diverse case studies through the Caribbean. These systems were analyzed at different levels: animal/function, farm/family, and territory/society. This produced a set of guidelines that help to increase the efficiency of tropical systems, particularly those concerned with (1) choosing the best-suited genotypes, while enhancing population biodiversity; (2) matching the farming system to the available resources, feed, and by-products; (3) steering the whole farming system through reproduction management with no hormonal treatment, while facilitating system reproducibility and increasing performances; (4) controlling health constraints instead of annihilating risks and implement an integrated management design to reduce chemical treatments or increase the use of nutraceuticals; and (5) mitigating climate constraints by using soft techniques. In the second part of this work, some integrated systems are described. The Tosoly farm of Colombia, for instance, is conceived as a totally integrated crop-livestock system, allowing the additional production of energy at the farm level. Thus, it epitomizes the positive impact that livestock can exert upon the environment. The case study of Haiti indicates how AE practices can help in designing a pro-poor sustainable milk production system. It concerns an entire dairy sector built all over the country on the basis of micro-units of milk production and processinginfo:eu-repo/semantics/acceptedVersio
