Proportional Variation of Potential Groundwater Recharge as a Result of Climate Change and Land-Use: A Study Case in Mexico

Artículo en revista indexadaThis work proposes a methodology whereby the selection of hydrologic and land-use cover change (LUCC) models allows an assessment of the proportional variation in potential groundwater recharge (PGR) due to both land-use cover change (LUCC) and some climate change scenarios for 2050. The simulation of PGR was made through a distributed model, based on empirical methods and the forecasting of LUCC stemming from a supervised classification with remote sensing techniques, both inside a Geographic Information System. Once the supervised classification was made, a Markov-based model was developed to predict LUCC to 2050. The method was applied in Acapulco, an important tourism center for Mexico. From 1986 to 2017, the urban area increased 5%, and by 2050 was predicted to cover 16%. In this period, a loss of 7 million m3 of PGR was assumed to be caused by the estimated LUCC. From 2017 to 2050, this loss is expected to increase between 73 and 273 million m3 depending on the considered climate change scenario, which is the equivalent amount necessary for satisfying the water needs of 6 million inhabitants. Therefore, modeling the variation in groundwater recharge can be an important tool for identifying water vulnerability, through both climate and land-use change.CONACyT Centro de Ciencias de Desarrollo Regional (CCDR

Noviazgos violentos

En el marco de la Licenciatura de la carrera de Comunicación Social y Periodismo de la Universidad Nacional de La Plata, decidimos analizar la “Violencia en el Noviazgo”. En la provincia se tratan temáticas relacionadas con la sensibilización sobre la ley 26.485 de “Protección Integral para prevenir, sancionar y erradicar la violencia contra las mujeres en los ámbitos en que desarrollen sus relaciones interpersonales”, pero no orientado hacia el noviazgo. La violencia en el noviazgo es una problemática que siempre existió, pero nunca se trató con la relevancia que en verdad merece. Las estadísticas realizadas por la Secretaría de la Mujer de la Provincia de Formosa junto al Instituto del Género de la Universidad Nacional de Formosa, durante el periodo 2013/14 señala que de cada 10 personas 4 presentan denuncias relacionadas a problemas vinculares en la pareja.Facultad de Periodismo y Comunicación Socia

Eficacia de un programa para el tratamiento del sobrepeso y la obesidad no mórbida en atención primaria y su influencia en la modificación de estilos de vida

Introducción y Objetivos: la modificación de conductas no saludables es fundamental para tratar la obesidad. El objetivo de este estudio fue evaluar los efectos de un programa basado en dieta, ejercicio y apoyo psicológico en la modificación conductual de pacientes con sobrepeso y obesidad tratados en Atención Primaria. Métodos: 60 pacientes con sobrepeso grado II y obesidad grado I-II fueron incluidos en este ensayo piloto. Edad entre 18-50 años. Los pacientes recibieron un programa que combinaba educación nutricional, actividad física y apoyo psicológico. Formato grupal, periodicidad quincenal. Los principales resultados medidos al inicio y 6 meses fueron parámetros antropométricos (índice de masa corporal, porcentaje de masa grasa, perímetro cintura) y de estilos de vida usando el Cuestionario para la valoración de hábitos de vida relacionados con el sobrepeso y la obesidad. Consta de 5 dimensiones: contenido calórico de la dieta (CC), alimentación saludable (AS), ejercicio físico (EF), comer por bienestar psicológico (BP) y consumo de alcohol (CA). La mayor puntuación indica mejores hábitos para CC, AS y EF y peores para BP y CA. Resultados: al final de la intervención mejoraron las escalas CC (2,60± 0,5 vs 3,49± 0,7, p<0,001), EF (2,19± 0,9 vs 3,17± 1,0, p<0,001) y AS (3,04± 0,4 vs 3,43± 0,4, p<0,05) del cuestionario; CA (3,98± 0,7 vs. 4,25± 0,7, p<0,05) y BP (2,82± 1,0 vs. 3,34± 0,7, p<0,001) empeoraron. Conclusión: el programa basado en moderada restricción de la dieta, aumento de actividad física y apoyo psicológico puede mejorar parámetros antropométricos y estilos de vida en pacientes obesos tratados en un centro de Atención PrimariaBackground: Lifestyle intervention is fundamental for obesity treatment. The aim of this study was to evaluate the effects of a program focused on diet, exercise and psychological support on Lifestyle Modification in overweight and obese patients treated in Primary Health Care setting. Methods: 60 patients with grade II overweight and non-morbid grade I-II obesity were included in this pilot clinical trial. Ages ranged from18 to 50 years. They were provided with a program combining nutritional education, physical activity and psychological support. Subjects attended group sessions every 2 weeks. The main outcome measures at baseline and 6 months were body composition parameters (BMI, body fat percentage, waist circumference) and lifestyle intervention using the Questionnaire for the assessment of overweight and obesity related lifestyles at baseline and six months. This questionnaire yields an five dimensions: diet caloric intake (CC), healthy eating (AS), physical activity (EF), searching for psychological well-being eating (BP) and alcohol intake (CA). The higher score indicates better lifestyles for CC, AS, EF and worse for BP y CA. Results: At the end of the intervention the program achieved improvements in Questionnaire related lifestyles subscales: CC (2,60± 0,5 vs. 3,49± 0,7, p<0,001), EF (2,19± 0,9 vs. 3,17± 1,0, p<0,001) and AS (3,04± 0,4 vs. 3,43± 0,4, p<0,05); CA (3,98± 0,7 vs. 4,25± 0,7, p<0,05) and BP (2,82± 1,0 vs. 3,34± 0,7, p<0,001) has got worse. Conclusion: The Program focused on balanced and moderate energy-restricted diets, increased physical activity and psychological support may improve the anthropometric parameters and the Lifestyle intervention in obese patients treated in a primary healthcare center.Este proyecto ha sido becado por el Ministerio de Ciencia e Innovación, a través del Instituto de Salud Carlos III y la Subdirección General de Evaluación y Fomento de la Investigación, en el marco del «Subprograma de Proyectos de Investigación de Evaluación de Tecnologías Sanitarias e Investigación en servicios de salud».

On the Dissociation Pathways of Copper Complexes Relevant as Pet Imaging Agents

[Abstract] Several bifunctional chelators have been synthesized in the last years for the development of new 64Cu-based PET agents for in vivo imaging. When designing a metal-based PET probe, it is important to achieve high stability and kinetic inertness once the radioisotope is coordinated. Different competitive assays are commonly used to evaluate the possible dissociation mechanisms that may induce Cu(II) release in the body. Among them, acid-assisted dissociation tests or transchelation challenges employing EDTA or SOD are frequently used to evaluate both solution thermodynamics and the kinetic behavior of potential metal-based systems. Despite of this, the Cu(II)/Cu(I) bioreduction pathway that could be promoted by the presence of bioreductants still remains little explored. To fill this gap we present here a detailed spectroscopic study of the kinetic behavior of different macrocyclic Cu(II) complexes. The complexes investigated include the cross-bridge cyclam derivative [Cu(CB-TE1A)]+, whose structure was determined using single-crystal X-ray diffraction. The acid-assisted dissociation mechanism was investigated using HClO4 and HCl to analyse the effect of the counterion on the rate constants. The complexes were selected so that the effects of complex charge and coordination polyhedron could be assessed. Cyclic voltammetry experiments were conducted to investigate whether the reduction to Cu(I) falls within the window of common bioreducing agents. The most striking behavior concerns the [Cu(NO2Th)]2+ complex, a 1,4,7-triazacyclononane derivative containing two methylthiazolyl pendant arms. This complex is extremely inert with respect to dissociation following the acid-catalyzed mechanism, but dissociates rather quickly in the presence of a bioreductant like ascorbic acid.The authors thank Ministerio de Ciencia e Innovación (PID2019-104626GB-I00) and Xunta de Galicia (ED431B 2020/52) for generous financial support.

Predictor variables for low adherence to a lifestyle modification program of overweight treatment in primary health care

Objetivos: Identificar variables predictoras de baja adherencia a un programa piloto de Modificación de Estilos de Vida (MEV) para el tratamiento del exceso de peso en Atención Primaria (AP). Material y métodos: Se reclutaron 60 sujetos con IMC > 27 kg/m². Profesionales sanitarios dirigieron el programa, en formato grupal y con una periodicidad quincenal, basado en educación nutricional, pautas dietéticas individualizadas, promoción de actividad física y apoyo motivacional. Para identificar las variables relacionadas con la adherencia al programa se utilizó un cuestionario validado sobre Hábitos de Vida de personas con Sobrepeso y Obesidad y se midieron variables antropométricas al inicio y a los seis meses del tratamiento. Una baja adherencia al programa fue considerada cuando los sujetos del estudio acudían a menos del 80% de las visitas quincenales. Resultados: Se adhirieron al programa 27 sujetos (45%). Las variables asociadas a baja adherencia estuvieron relacionadas al inicio del estudio con IMC ≥ 35 kg/m2 (p < 0,05); período de exfumador ≤ 4 meses (p < 0,01); mayor contenido calórico de la dieta (p < 0,01) y menor práctica de ejercicio físico (p < 0,05). A los 6 meses los sujetos que finalizaron el programa presentaron una disminución significativa de: peso (86,0 ± 15,6 vs 79,2 ± 13,4 kg; p < 0,001);% de masa grasa (41,6 ± 4,6 vs 38,8 ± 5,4%; p < 0,001) y glucemia (108 ± 45,48 vs 94,38 ± 11,97 mg/dl; p < 0,01). Además mejoró el perfil calórico de su dieta, disminuyendo sobretodo el porcentaje de grasa sobre el valor calórico total (39,6 ± 4,8 vs. 35,5 ± 5,6%; p < 0,01). Conclusión: Haber dejado de fumar recientemente, padecer obesidad de grado dos o superior, el alto contenido calórico de la dieta y la menor práctica de ejercicio físico fueron las variables basales identificadas como predictoras de una baja adherencia a un programa de MEV para el tratamiento de sobrepeso y obesidad en AP. Esta experiencia piloto una vez evaluada no la consideramos satisfactoria y otras nuevas estrategias están en fase de desarrolloObjectives: To identify predictive variables of low adherence to a pilot Lifestyle Modification Program (LMP) for overweight and obesity treatment in primary health care (PC ). Material and methods: Sixty subjects with BMI > 27 kg/m² were recruited. Health professionals directed the program in a group structure and biweekly, based on nutrition education with individualized dietary guidelines, promotion of physical activity and motivational support. A validated questionnaire on lifestyle habits for overweight and obesity subjects was used to identify variables related with program adherence and anthropometric variables were measured before and 6 months after intervention. Low adherence was considered when patients attended to less than 80% of visits. Results: Twenty-seven subjects (45%) presented high adherence to the program. The variables associated to low adherence were related to baseline with IMC ≥ 35 kg/m2 (p < 0.05); ex smoker period ≤ 4 months (p < 0.01); high caloric diet (p < 0.01) and scarce physical activity (p < 0.05). At 6 months the subjects who finalized the program presented a significant decrease of weight (86.0 ± 15.6 vs 79.2 ± 13.4 kg; p < 0,001); fat mass percentage (41,6 ± 4,6 vs 38.8 ± 5,4%; p < 0.001), blood glucose (108 ± 45.48 vs 94.38 ± 11.97 mg/dl; p < 0.01). It also improved caloric diet profile, above all decreasing the percentage of fat (39.6 ± 4.8 vs 35.5 ± 5.6%; p < 0.01). Conclusion: Have recently left smoking, obesity degree two or higher, a high caloric diet and scarce physical activity were basal variables identified as predictive of a low adhesion to a LMP for the treatment of overweight and obesity in primary health care. We do not consider this pilot experience as satisfactory and other new strategies are under developmentEste proyecto ha sido subvencionado a través del “Subprograma de Proyectos de Investigación de Evaluación de Tecnologías Sanitarias e Investigación en servicios de salud” de la convocatoria 2008 de ayudas de la Acción Estratégica en Salud, en el marco del Plan Nacional de I+D+I 2008-201

Burnout in Nursing Managers: A Systematic Review and Meta-Analysis of Related Factors, Levels and Prevalence

This study forms part of the Doctoral Thesis of the first-named author within the Psychology Doctoral Program from the University of Granada.Burnout syndrome is a major problem in occupational health, which also affects nursing managers. The main aim was to analyze the level, prevalence and risk factors of burnout among nursing managers. A systematic review with meta-analysis was conducted. The databases used were Medline (Pubmed), PsycINFO, CINAHL, LILACS, Scielo and Scopus. The search equation was “burnout AND nurs* AND (health manager OR case managers)”. Nursing managers present high levels of emotional exhaustion and a high degree of depersonalization. Some studies show that variables like age, gender, marital status, having children or mobbing and other occupational factors are related with burnout. The prevalence estimation of emotional exhaustion with the meta-analysis was high; 29% (95% CI = 9–56) with a sample of n = 780 nursing managers. The meta-analytical estimation of the correlation between burnout and age was r = −0.07 (95% CI = −0.23–0.08). Work overload, the need to mediate personnel conflicts, lack of time and support from superior staff, contribute to the development of burnout among nursing managers.Junta de Andalucia P11HUM-777

Prevalence, levels and related factors of burnout in nurse managers: A multi-centre cross-sectional study

Aims: The aims of this study are to analyse the prevalence and levels of burnout syndrome in nurse managers and to evaluate the relationship between burnout and related sociodemographic, occupational and psychological factors. Background: Burnout syndrome, defined as an emotional response to chronic stress, is a major problem among nurse managers. Methods: The study was conducted using a cross-sectional survey design and data collected by the Maslach Burnout Inventory, the revised NEO Five Factor Inventory and the Educational-Clinical Questionnaire for Anxiety and Depression. The sample population consisted of 86 nurse managers from different hospitals from the Public Health Service of Andalusia, Spain. Results: A total of 22.4% of the participants presented high levels of emotional exhaustion, 21% experienced depersonalisation and 57.6% had little sense of personal accomplishment. Working long shifts was related to burnout. Emotional exhaustion and depersonalization were predicted by depression, while personal accomplishment was predicted by conscientiousness, agreeableness and openness. Conclusions: A total of 34.1% of the participants presented high levels of burnout, manifested by feelings of low personal accomplishment. Psychological and occupational factors play an important role in the development of this syndrome. Implications for Nursing Management: Nurse managers should seek to detect burnout among staff and colleagues matching the risk profile for this condition and promote interventions to prevent it

Preservation of anti-SARS-CoV-2 neutralising antibodies in convalescent plasma after pathogen reduction with methylene blue and visible light

Background - COVID-19 convalescent plasma (CCP) is an experimental treatment against SARS-CoV-2. Although there has so far been no evidence of transmission through transfusion, pathogen reduction technologies (PRT) have been applied to CCP to mitigate risk of infectious disease. This study aims to assess the impact of methylene blue (MB) plus visible light PRT on the virus-neutralising activity of the specific antibodies against SARS-CoV-2. Material and methods - Thirty-five plasma doses collected by plasmapheresis from COVID-19 convalescent donors were subjected to MB plus visible light PRT. Anti-SARS-CoV-2 RBD S1 epitope IgGs antibodies were quantified by ELISA. Titres of SARS-CoV-2 neutralising antibodies (NtAbs) were measured before and after the PRT process. A Spearman's correlation was run to determine the relationship between antibody neutralisation ability and SARS-CoV-2 IgG ELISA ratio. Pre- and post-inactivation neutralising antibody titres were evaluated using a Wilcoxon test. Results - The plasma pathogen reduction procedure did not diminish NtAbS titres and so did not cause a change in the viral neutralisation capacity of CCP. There was a strong correlation between pre-and post-PRT NtAbs and anti-SARS-CoV-2 IgGs titres. Discussion - Our results showed PRT with MB did not impair the CCP passive immunity preserving its potential therapeutic potency. Therefore, PRT of CCP should be recommended to mitigate the risk for transmission of transfusionassociated infectious disease. There is a good correlation between SARS-CoV-2 IgG titres determined by ELISA and the neutralising capacity. This allows blood centres to select CCP donors based on IgG ELISA titres avoiding the much more labour-intensive laboratory processes for determining neutralising antibodies.Peer reviewe
