A Sum of Incidentals or a Structural Problem? The True Nature of Food Waste in the Metropolitan Region of Barcelona
Addressing the generation of food waste is a major challenge nowadays. An increasing
interest in studying food waste generation has emerged over the last decade. However, little attention
has been devoted to understanding the root of the problem by carrying out a whole-supply-chain
analysis and applying multidimensional approaches. The aim of this paper was to identify the causes
of food waste in the metropolitan region of Barcelona along the food supply chain, considering the
relevant stakeholders’ perceptions. Moreover, we examined the circumstantial or structural nature
of the identified causes. We conducted a qualitative study consisting of 24 in-depth interviews
of key stakeholders in the region along the food supply chain from October 2014 to January 2015.
The interviews were analyzed by content analysis, and the main results are presented here. We used
a conceptual framework that differentiates among micro, meso, and macro causes to disentangle the
nature of the causes. The results from this study show the great interest of regional stakeholders in
the issue of the generation of food waste and provide a complete map of the causes of food waste in
the metropolitan region. From our study, we advocate that food waste is not only a sum of incidentals
but it a structural problem.info:eu-repo/semantics/publishedVersio
High spatial heterogeneity and low connectivity of bacterial communities along a Mediterranean subterranean estuary
Unidad de excelencia María de Maeztu CEX2019-000940-MSubterranean estuaries are biogeochemically active coastal sites resulting from the underground mixing of fresh aquifer groundwater and seawater. In these systems, microbial activity can largely transform the chemical elements that may reach the sea through submarine groundwater discharge (SGD), but little is known about the microorganisms thriving in these land-sea transition zones. We present the first spatially-resolved characterization of the bacterial assemblages along a coastal aquifer in the NW Mediterranean, considering the entire subsurface salinity gradient. Combining bulk heterotrophic activity measurements, flow cytometry, microscopy and 16S rRNA gene sequencing we find large variations in prokaryotic abundances, cell size, activity and diversity at both the horizontal and vertical scales that reflect the pronounced physicochemical gradients. The parts of the transect most influenced by freshwater were characterized by smaller cells and lower prokaryotic abundances and heterotrophic production, but some activity hotspots were found at deep low-oxygen saline groundwater sites enriched in nitrite and ammonium. Diverse, heterogeneous and highly endemic communities dominated by Proteobacteria, Patescibacteria, Desulfobacterota and Bacteroidota were observed throughout the aquifer, pointing to clearly differentiated prokaryotic niches across these transition zones and little microbial connectivity between groundwater and Mediterranean seawater habitats. Finally, experimental manipulations unveiled large increases in community heterotrophic activity driven by fast growth of some rare and site-specific groundwater Proteobacteria. Our results indicate that prokaryotic communities within subterranean estuaries are highly heterogeneous in terms of biomass, activity and diversity, suggesting that their role in transforming nutrients will also vary spatially within these terrestrial-marine transition zones
Presencia e influencia de sintomatología sugestiva de trastorno por déficit de atención e hiperactividad en adultos con un trastorno de la conducta alimentaria
Fundamento. La coexistencia de trastornos de la conducta alimentaria (TCA) y del trastorno por déficit de atención e hiperactividad
(TDAH) es frecuente. El objetivo del estudio fue cuantificar la presencia de sintomatología TDAH en pacientes adultos con TCA y evaluar posibles correlaciones entre ambas sintomatologías.
Material y métodos. Estudio transversal en pacientes con TCA. Se
cumplimentaron los cuestionarios Eating Attitudes Test de 40 ítems
(EAT-40), Eating Disorder Inventory 3ª edición (EDI-3) y la versión
abreviada del Adult ADHD Self-Report Scale (ASRS v1.1). Aquellos
pacientes con ≥12 puntos en ASRS v1.1 completaron el cuestionario
Attention Déficit Hyperactivity Disorder Rating Scale 4ª edición (ADHD-RS IV).
Resultados. El 42,6% de los 108 pacientes incluidos puntuaron ≥12
en el ASRS v1.1. Estos sujetos puntuaron más en bulimia y en algunas escalas de desajuste psicológico del EDI-3, y aquellos con
conductas de atracón y/o purga puntuaron más en Trastornos psicobiológicos del EAT-40 y en Insatisfacción corporal y Riesgo de
TCA del EDI-3. No hubo diferencias en ADHD-RS IV según fueran
cuadros restrictivos puros (n=13) o compulsivo-purgativos (n=33).
La sintomatología TDAH correlacionó más con la clínica alimentaria y con el desajuste psicológico general en los casos compulsivo-purgativos.
Conclusiones. En población clínica con TCA son frecuentes los síntomas sugestivos de TDAH, más en cuadros con clínica compulsivo-purgativa pero no necesariamente más intensos. La correlación
entre TDAH y TCA es mayor en cuadros compulsivo-purgativos. Los
síntomas de TDAH conllevan mayor desajuste psicológico y mayor
gravedad a nivel alimentario en los cuadros con sintomatología
compulsivo-purgativa.Background. The coexistence of eating disorders (ED) and attention deficit hyperactivity disorder (ADHD) is common. The aim of
the study was to quantify the presence of ADHD symptoms in adult
patients with ED and evaluate any possible correlation between
both symptomatologies.
Methods. Cross-sectional study of patients with ED. The following
questionnaires were completed: the Eating Attitudes Test - 40 items
(EAT-40), the Eating Disorder Inventory 3rd edition (EDI-3) and the
abbreviated version of the Adult ADHD Self-Report Scale (ASRS
v1.1). The patients who scored ≥12 points in ASRS v1.1 completed
the Attention Deficit Hyperactivity Disorder Rating Scale (4th edition, ADHD-RS IV).
Results. 42.6% of the 108 patients scored ≥12 in the ASRS v1.1. These subjects scored higher in bulimia and in some scales of psychological maladjustment of the EDI-3, and those with binging and/or
purging behaviours scored higher in Psychobiological disorders of
the EAT-40 and in Body dissatisfaction and Eating disorder risk composite scales of the EDI-3. There were no differences in ADHD-RS IV
between pure restrictive syndromes (n=13) and those with binging
and/or purging behaviours (n=33). We found that, in cases with binge/purge symptoms, ADHD symptoms correlated higher with ED
symptoms and with general psychological maladjustment.
Conclusion. ADHD symptoms are common in the clinical population with ED, and more in groups with binge/purge symptoms although they are not necessarily more intense. The correlation between ADHD symptoms and ED is higher in cases with binging and/
or purging behaviours. ADHD symptoms involve more psychological maladjustment and more serious ED symptomatology in cases
with binge/purge symptoms
Exploring the relation between childhood trauma, temperamental traits and mindfulness in borderline personality disorder
Background: Deficits in mindfulness-related capacities have been described in borderline personality disorder (BPD). However, little research has been conducted to explore which factors could explain these deficits. This study assesses the relationship between temperamental traits and childhood maltreatment with mindfulness in BPD. Methods: A total of 100 individuals diagnosed with BPD participated in the study. Childhood maltreatment was assessed using the Childhood Trauma Questionnaire (CTQ-SF), temperamental traits were assessed using the Zuckerman-Khulman Personality Questionnaire (ZKPQ), and mindfulness capabilities were evaluated with the Five Facet Mindfulness Questionnaire (FFMQ). Results: Hierarchical regression analyses were performed including only those CTQ-SF and ZKPQ subscales that showed simultaneous significant correlations with mindfulness facets. Results indicated that neuroticism and sexual abuse were predictors of acting with awareness; and neuroticism, impulsiveness and sexual abuse were significant predictors of non-judging. Temperamental traits did not have a moderator effect on the relationship between childhood sexual abuse and mindfulness facets. Conclusions: These results provide preliminary evidence for the effects of temperamental traits and childhood trauma on mindfulness capabilities in BPD individuals. Further studies are needed to better clarify the impact of childhood traumatic experiences on mindfulness capabilities and to determine the causal relations between these variables
Experiences of patients with chronic low back pain plus comorbid depressive symptoms in a videoconference group acceptance and commitment therapy or behavioral activation treatment for depression : a qualitative study
PURPOSE: To explore the experiences of patients with chronic low back pain (CLBP) plus comorbid depressive symptoms who received a remote synchronous videoconference group form of Acceptance and Commitment Therapy (ACT) or Behavioral Activation Treatment for Depression (BATD). METHODS: A qualitative study (IMPACT-Q) was nested within a randomized controlled trial (RCT) designed to assess the efficacy and the cost-utility/cost-effectiveness of two therapies in the management of CLBP and depression. Fifty-five patients with CLBP plus depression were selected from the RCT. Twelve focus group sessions, each approximately 60-90 min long, were audio-recorded, transcribed verbatim, and analyzed by six coders through a thematic analysis (deductive and inductive) based on a descriptive phenomenological approach. RESULTS: Patients perceived behavioral, affective, and cognitive improvements after completing group sessions. Overall, psychotherapy was perceived as a safe and non-judgmental place to express emotions and feel understood. The main barriers reported were lack of human contact and loss of social interaction. In contrast, ease of access, flexibility in the ability to connect from anywhere, avoidance of the need to travel, and savings in time and money were key facilitators to increase attendance and adherence to therapy. CONCLUSION: This study provided support for the acceptability of videoconference-delivered ACT or BATD in patients with CLBP plus comorbid depressive symptoms
Comparison of Migration Disturbance Potency of Epigallocatechin Gallate (EGCG) Synthetic Analogs and EGCG PEGylated PLGA Nanoparticles in Rat Neurospheres
Epigallocatechin gallate (EGCG), the main catechin of green tea, is described to have potential health benefits in several fields like oncology, neurology or cardiology. Currently, it is also under pre-clinical investigation as a potential therapeutic or preventive treatment during pregnancy against developmental adverse effects induced by toxic substances. However, the safety of EGCG during pregnancy is unclear due to its proven adverse effects on neural progenitor cells' (NPCs) migration. As lately several strategies have arisen to generate new therapeutic agents derived from EGCG, we have used the rat 'Neurosphere Assay' to characterize and compare the effects of EGCG structurally related compounds and EGCG PEGylated PLGA nanoparticles on a neurodevelopmental key event: NPCs migration. Compounds structurally-related to EGCG induce the same pattern of NPCs migration alterations (decreased migration distance, decreased formation of migration corona, chaotic orientation of cellular processes and decreased migration of neurons at higher concentrations). The potency of the compounds does not depend on the number of galloyl groups, and small structure variations can imply large potency differences. Due to their lower toxicity observed in vitro in NPCs, 4,4′-bis[(3,4,5-trihydroxybenzoyl)oxy]-1,1′-biphenyl and EGCG PEGylated PLGA nanoparticles are suggested as potential future therapeutic or preventive alternatives to EGCG during prenatal period
Las alteraciones metabólicas asociadas a la obesidad están ya presentes en los primeros años de vida: estudio colaborativo español
Los objetivos de este estudio son, realizar una descrip-ción de las características demográficas, antropométricas y de las alteraciones metabólicas de niños atendidos por obe-sidad resaltando las características aquellos casos de obesidad de inicio temprano (< 10 años) y los de inicio precoz (< 5 años), y evaluar la capacidad diagnóstica de la definición de síndrome metabólico (SM) según diferentes criterios.
Métodos: Es un estudio retrospectivo, caso-control, trans-versal, multicéntrico. Han participado un total de 10 Uni-dades de Endocrinología Pediátrica de diferentes hospitales españoles con un grupo de 469 niños con obesidad de inicio temprano y otro grupo de 30 niños con obesidad de inicio precoz. El grupo control estuvo constituido por 224 niños sanos menores de 10 años. Se realizó una valoración antro-pométrica y determinación analítica de parámetros del me-tabolismo de los hidratos de carbono y lipidograma.
Resultados: La presencia de alteraciones metabólicas asociadas a la obesidad en la etapa infanto-juvenil en Espa-ña es notable, de forma aislada, o englobada bajo la defini-ción de SM. La prevalencia de éste aumenta sustancialmen-te cuando se considera la resistencia periférica a la acción de la insulina como criterio diagnóstico. Se demuestra cómo en niños menores de 10 años, dichas alteraciones están presen-tes en un porcentaje reseñable, y se encuentran las primeras alteraciones metabólicas ya en niños obesos < 5 años.
Conclusión: En los niños españoles existen alteracio-nes metabólicas asociadas a la obesidad en la etapa in-fanto-juvenil de forma aislada o englobada bajo la de-finición de SM, y ya están presentes a edades precoces.
The objectives of this study are to provide a description of the demographic, anthropometric characteristics and metabolic abnormalities in children with early-onset (< 10 years) and of very-early-onset obesity (< 5 years). We also evaluate the diagnostic ability using the definition of meta-bolic syndrome (MS) according to different criteria.
Methods: It is a retrospective, case-control, cross-sec-tional, multicenter study. A total of 10 Pediatric Endo-crinology Units in different Spanish hospitals were in-volved. A group of 469 children with early-onset obesity and another group of 30 children with very early-onset obesity were studied. The control group consisted of 224 healthy children younger than 10 years. Anthropometric and analytical determination of carbohydrates metabo-lism parameters and the lipid profile were performed.
Results: The presence of metabolic alterations associa-ted with obesity in children and adolescents in Spain is remarkable, either on their own, or encompassed within the definition of MS. This prevalence increases substan-tially when considering the peripheral resistance to in-sulin action as a diagnostic criterion. It also shows how children who could not be diagnosed with MS according to the definition provided by the International Diabetes Federation (IDF) due to age below 10 years, these altera-tions are already present in a remarkable percentage. In fact, metabolic abnormalities are already present in the very-early-onset obese children (<5 years).
Conclusion: In Spanish children there are metabolic alterations associated with obesity in the infant-juvenile stages alone or encompassed within the definition of MS, and are already present at earlier ages
FOSL1 promotes cholangiocarcinoma via transcriptional effectors that could be therapeutically targeted
Understanding the molecular mechanisms involved in cholangiocarcinoma (bile duct cancer) development and progression stands as a critical step for the development of novel therapies. Through an inter-species approach, this study provides evidence of the clinical and functional role of the transcription factor FOSL1 in cholangiocarcinoma. Moreover, we report that downstream effectors of FOSL1 are susceptible to pharmacological inhibition, thus providing new opportunities for therapeutic intervention
Clinico-pathological characteristics and outcomes of patients with early-onset colorectal cancer
[Background]: The rising incidence of colorectal cancer (CRC) among young patients is alarming. We aim to characterize the clinico-pathological features and outcomes of patients with early-onset CRC (EOCRC).
[Methods]: We included all of the patients with pathologically confirmed diagnosis of CRC at Hospital Universitario La Paz from October 2016 to September 2020. EOCRC age cut-off was 50 years. All statistical analyses were carried out using SPSS v.25.
[Results]: A total of 1152 patients were diagnosed with CRC, fifty-nine (5,1%) of them were After a median follow-up of 24 months, 279 patients have died. Median overall survival (OS) was not reached in either group (p = 0,06). Three-year OS was 80% (95%CI: 73-87) and 67 (95%CI: 65-69) in the younger and older group, respectively. In patients with localized disease that underwent surgery or other antineoplastic treatment ( n = 856), 159 events for disease-free survival (DFS) were observed. Median DFS was
[Conclusions]: Patients with EOCRC are diagnosed at a more advanced stage and display distinct biological features (more prevalence of dMMR and WT tumors among others). Studies focusing on screening in this population and deeper molecular profiling are needed
