Analysis of the budget impact of fractional exhaled nitric oxide monitoring in the management of childhood asthma: the Colombian National Health System perspective

Background: Fractional exhaled nitric oxide (FeNO) testing is a simple, noninvasive approach to assessing airway inflammation with minimal discomfort that provides results within a few minutes. For policy makers, the economic impact of this technology is the main concern, especially in developing countries. We evaluated the budget impact of asthma management using FeNO monitoring in patients aged between 4 and 18 years in Colombia. Methods: A budget impact analysis was performed to evaluate the potential cost of FeNO monitoring. The analysis was based on a 5-year time horizon and performed from the perspective of the Colombian National Health System. The incremental budget impact was calculated by subtracting the cost of the new treatment, in which FeNO is reimbursed, from the cost of conventional treatment without FeNO (management based on clinical symptoms [with or without spirometry/peak flow] or asthma guidelines [or both] for asthma-related cases). Univariate 1-way sensitivity analyses were performed. Results: In the base case analysis the 5-year costs associated with FeNO and non-FeNO were estimated to be €469 904 130 and €480 485 149, respectively, indicating savings for the Colombian National Health System of €10 581 019 if FeNO is adopted for the routine management of patients with persistent asthma. This result proved to be robust in the univariate 1-way sensitivity analysis. Conclusion: FeNO monitoring generated cost savings in emergency settings for infants with persistent asthma. This evidence can be used by decision makers in Colombia to improve clinical practice guidelines and should be replicated to validate the results in other middle-income countries

The State-Moro Armed Conflict in the Philippines: Unresolved national question or question of governance?

The continuing struggle of the Moro secessionist movement in the Philippines is one of Southeast Asia’s longest armed conflicts. The tenacity of the conflict lies in two competing concerns: the assertion of self-determination rights of the Moro separatist movement; and the affirmation of the Philippines’ sovereign right to territorial integrity. However, beneath these rights are crucial issues that remain unanswered both by the contending forces—problems where internecine violence and conflict emanate from. This article argues that self-determination rights can be adequately exercised by people who have clearly defined their national identity and concept of a nation. Unfortunately, the Moro multi-ethnic national identity has yet to be crystallised while the idea of a Bangsamoro (Bangsa Nation) remains weak. On the other hand, the state has yet to address the Moros’ legitimate demands of political autonomy, socio-economic development, and social justice and discrimination. Without underestimating the ethnic component of secessionism, the article concludes that poor governance has prolonged, complicated, and further justified the Moros’ quest to secede from the Republic

Fluid escape structures in the Gulf of Cadiz. Evidence of structural control from combined seismic reflection and sidescan sonar interpretation

The Gulf of Cadiz is situated in a tectonically complex and active region, close to a major plate boundary. The tectonic regime in the area is characterized by a combination of important strike-slip movement and compressional tectonics related to the Africa-Eurasia NW-directed convergence, responsible for the formation of the Gibraltar Arc. Extensive mud volcanism, pockmarks, mud diapirism and carbonate chimneys related to hydrocarbon rich fluid venting are observed throughout the area. There is an extensive coverage of seismic reflection profiles in the area that includes industry data, a few deep-multichannel lines (IAM, ARRIFANO and BIGSETS) and many single-channel lines (both Sparker and Airgun data). During the TTR-12 (July/2002) and the GAP (Nov-Dec/2003) cruises, several single and multi channel seismic lines were acquired in this area that complement the existing database collected during previous TTR Cruises. These lines have re-processed to enhance the deeper structure.A combined interpretation of the available side-scan sonar imaging obtained by the Naval Research Laboratory in 1992 and the available seismic lines (both single channel and multichannel) shows clear evidence of the structural control of the mud volcanism in the study area. In particular, it appears that some of the mud volcanoes are located at the intersection between NW-SE strike-slip faults and thrusts of variable orientation, reflecting the curvature of the Gibraltar Arc

Neuroprotective effects of EpoL against oxidative stress induced by soluble oligomers of Aβ peptide

Erythropoietin is a glycoproteic hormone that regulates hematopoiesis by acting on its specific receptor (EpoR). The expression of EpoR in the central nervous system (CNS) suggests a role for this hormone in the brain. Recently, we developed a new Epo variant without hematopoietic activity called EpoL, which showed marked neuroprotective effects against oxidative stress in brain ischemia related models. In this study, we have evaluated the neuroprotective effects of EpoL against oxidative stress induced by chronic treatment with Aβ. Our results show that EpoL was neuroprotective against Aβ-induced toxicity by a mechanism that implicates EpoR, reduction in reactive oxygen species, and reduction in astrogliosis. Furthermore, EpoL treatment improved calcium handling and SV2 levels. Interestingly, the neuroprotective effect of EpoL against oxidative stress induced by chronic Aβ treatment was achieved at a concentration 10 times lower than that of Epo. In conclusion, EpoL, a new variant of Epo without hematopoietic activity, is of potential interest for the treatment of diseases related to oxidative stress in the CNS such as Alzheimer disease.Grant Innova-Corfo “13IDL2-18688”; Conicyt Grant “Beca Doctorado Nacional no. 21130386”; Fondecyt Grant “1161078

Eventos no epilépticos psicógenos: El desafío constante de su diagnóstico y tratamiento.

Psychogenic Non-Epileptic Events (PNEE) are paroxysmal episodes described as behavioral changes, sensory- sensitive disturbances, or motor manifestations that resemble epileptic seizures without showing underlying epileptiform activity, are not deliberately produced by the individual, and respond to multifactorial biopsychosocial mechanisms. Epidemiological information is limited due to the heterogeneous nature of the affected population, and to the limited accessibility to the video electroencephalogram (vEEG) necessary for its diagnosis. In such context, the convergence of two important elements is necessary: a detailed clinical history (clinical characteristics suggestive of PNEE, and identification of the associated factors), and the absence of electroencephalographic “ictal” changes in the vEEG. A psychological evaluation provides additional information, relevant for the diagnostic corroboration and management. The diagnosis must be made in a timely manner, to avoid complications in its evolution and treatment. A positive and encouraging attitude to the patient is vital when informing him/her of the diagnosis, as it also is the coordination between the treating neurologist and mental health professionals involved in the management and monitoring of the case. Cognitive behavioral psychotherapy, associated with psychopharmacotherapy -when needed-- constitute the most effective treatment approach for these patients. There are limited studies on the current epidemiological and clinical evolution of patients with PNEE in Latin America, and additional research regarding this problem is much needed, given its impact on the quality of life of the patients and on the cost of its management in the health care systems.Los eventos no epilépticos psicógenos (ENEP) son episodios paroxísticos descritos como cambios conductuales, alteraciones sensorio-sensitivas, o manifestaciones motoras que se asemejan a las crisis epilépticas pero sin mostrar actividad epileptiforme subyacente, no son producidos deliberadamente por el individuo, y responden a mecanismos multifactoriales de índole biopsicosocial. La información epidemiológica es limitada debido a la naturaleza heterogénea de la población afectada, así como a la escasa accesibilidad al videoelectroencefalograma (vEEG) necesario para su diagnóstico. En este contexto, es necesaria la convergencia de dos elementos importantes: historia clínica detallada (características clínicas sugerentes de ENEP e identificación de los factores asociados) y la ausencia de cambios electroencefalográficos en el vEEG durante el episodio. La evaluación psicológica provee información adicional relevante para la corroboración diagnóstica y para su manejo. El diagnóstico debe realizarse de manera oportuna, para evitar complicaciones en su evolución y tratamiento. Es vital una actitud positiva y alentadora hacia el/la paciente al momento de comunicarle su diagnóstico, así como la coordinación entre el neurólogo tratante y los profesionales de salud mental involucrados en el manejo y seguimiento del caso. La psicoterapia cognitiva conductual, asociada a psicofármacoterapia -cuando pertinente-, constituyen el tratamiento más eficaz de estos pacientes. Existen limitados estudios en Latinoamérica sobre aspectos epidemiológicos y clínico-evolutivos de pacientes con ENEP, por lo que más investigación y publicaciones respecto a esta problemática son indispensables dado su impacto sobre la calidad de vida de los pacientes y sobre el costo de su manejo en los sistemas de salud
