Comparación de los puntajes PAS y Lintula en la sospecha diagnóstica de apendicitis en niños

Jorge Alberto Mujica Guevara, Mauricio Pierdant Pérez, Antonio Augusto Gordillo Moscoso, Marco Ulises Martínez Martínez, Raymundo Ramírez Meléndez
2018 Acta Pediátrica de México  
INTRODUCCIÓN: la apendicitis aguda es la principal causa de cirugía abdominal en niños. En ocasiones es difícil distinguir la apendicitis de otros padecimientos y ello puede retrasar el diagnóstico. Los puntajes PAS (Pediatric Apendicitis Score) y Lintula se basan en la existencia, o no, de síntomas y signos validados en oblación pediátrica. No existen estudios prospectivos (en el mismo grupo poblacional) que informen cuál de ellos es más útil en la evaluación del niño con sospecha de
more » ... s.OBJETIVOS: comparar los puntajes Lintula y PAS y establecer cuál es más confiable ante la sospecha diagnóstica de apendicitis en niños.MATERIALES Y MÉTODOS: estudio prospectivo efectuado en pacientes pediátricos de 4 a 15 años atendidos en el servicio de urgencias pediátricas de un hospital de segundo nivel de atención entre los meses de febrero y agosto de 2015, por dolor abdominal y sospecha de apendicitis. Ambos sistemas de puntaje se calificaron por paciente, el diagnóstico definitivo se estableció con base en el estudio anatomopatológico o la evolución clínica. RESULTADOS: se incluyeron 100 pacientes y la apendicitis se confirmó en 47. El puntaje Lintula promedio de casos sin apendicitis fue de 12.5 (DE ± 6.2) y con apendicitis 28.8 (DE ± 5.2) (p < 0.001). La puntuación media para PAS en los casos sin apendicitis fue de 4.3 (DE ± 2.1) y con apendicitis 8.3 (DE ± 1.5) (p < 0.001). El mejor punto de corte en las curvas ROC fue de 20 para Lintula y 6 para PAS. Para Lintula la sensibilidad fue de 89.4%, especificidad 90.6% y área bajo la curva de 0.942. El PAS arrojó sensibilidad 95.7%, especificidad 75.5% y área bajo la curva de 0.924. No se encontraron diferencias significativas entre los instrumentos.CONCLUSIONES: puesto que ambos instrumentos tienen sensibilidad y especificidad apropiadas debe alentarse su aplicación en la valoración de la sospecha de apendicitis en niños.

Valuing the Impact of Forest Disturbances on the Climate Regulation Service of Western U.S. Forests

Raymundo Marcos-Martinez, José J. Sánchez, Lorie Srivastava, Natthanij Soonsawad, Dominique Bachelet
2022 Sustainability  
The protection and expansion of forest carbon sinks are critical to achieving climate-change mitigation targets. Yet, the increasing frequency and severity of forest disturbances challenge the sustainable provision of forest services. We investigated patterns of forest disturbances' impacts on carbon sinks by combining spatial datasets of forest carbon sequestration from biomass growth and emissions from fire and bark beetle damage in the western United States (U.S.) and valued the social costs
more » ... of forest carbon losses. We also examined potential future trends of forest carbon sinks under two climate-change projections using a global vegetation model. We found that forest carbon losses from bark-beetle damage were larger than emissions from fires between 2003 and 2012. The cumulative social costs of forest carbon losses ranged from USD 7 billion to USD 72 billion, depending on the severity of global warming and the discount rate. Forest carbon stocks could increase around 5% under Representative Concentration Pathway (RCP) 4.5 or 7% under RCP 8.5 by 2091 relative to 2011 levels, mostly in forests with high net primary productivity. These results indicate that spatially explicit management of forest disturbances may increase forest carbon sinks, thereby improving opportunities to achieve critical climate-change mitigation goals.

Fuelling regional development or exporting value? The role of the gas industry on the Limestone Coast, South Australia

Thomas G. Measham, Lavinia Poruschi, Raymundo Marcos-Martinez
2020 The Extractive Industries and Society  
The degree to which host regions benefit from resource extraction is a major issue for research and policy. In Australia and Canada, the dominant narrative of resource extraction is that most of the benefits flow away from host regions. This paper draws on evolutionary economic geography, presenting a case study of the Limestone Coast in South Australia, which previously extracted and distributed gas locally to food and fibre manufacturing industries. New policies seeking to renew the gas

Qualitative analysis of the scenarios emphasised that gas needs to be affordable and locally accessible. Quantitative modelling showed that using the gas locally by manufacturing industries as part of broader industrial expansion would lead to greater benefits compared with exporting all gas outside the region. We conclude that policy settings have gone some way towards realising increased benefits for the region. Regional stakeholders clearly favoured the local use scenario but saw it as unlikely in the context of current infrastructure limitations. Stakeholders sought policy support for infrastructure to enable the preferred scenario to be realised.

The Influences of Livelihood and Land Use on the Variation of Forest Transition in a Typical Mountainous Area of China

Longhui Lu, An Huang, Yueqing Xu, Raymundo Marcos-Martinez, Yaming Duan, Zhengxin Ji
2020 Sustainability  
As one of the countries which that has been experiencing a forest transition, China provides important insights into and theoretical and empirical knowledge of forest transition. In this study, through the framework of Sustainable Livelihood Analysis (SLA) and questionnaire surveys, we examined forest transition, farmers' land-use activities and livelihood changes in Chicheng county, a typical mountainous area in Northern China, during 1975–2018. Most villages of Chicheng county experienced

Forest transition variation over time was influenced by land use and livelihood changes. Livelihood resources, policy and institutional constraints and livelihood strategies had significant influences on land use and then caused variation in forest transition characteristics. The process of "livelihood–land use–forest transition" was the key to achieving and maintaining forest transition, and the interaction between livelihood and land use was a negative feedback relationship between society and ecology. The dominant path of forest transition in Chicheng county was the "economic development path". Moreover, the "intensive agriculture path of small-scale farmers" enhanced the "economic development path", and the "forest scarcity path" promoted both of the above two paths. This implies that the feedback and interactions between society and ecology should be taken into account so as to achieve a sustainable human and environmental system.
