Introduction More than 600 thousand people in Chile live with morbid obesity. Effective, safe, cost-effective therapeutic interventions are critical for healthcare systems and insurance schemes. In 2022, two bundled payment codes for bariatric surgery (gastric bypass and gastric sleeve) were incorporated into the National Health Fund's free-choice modality fee scheme. The objective was to characterize the execution of this payment mechanism program associated with bariatric surgery diagnosis in its first year of implementation.More than six hundred thousand people in Chile are estimated to live with morbid obesity. Effective, safe, cost-effective therapeutic interventions are critical for health systems and insurance schemes. In 2022, FONASA incorporated two Bariatric Surgery codes into the Free Choice Modality: Gastric Bypass and Sleeve Gastrectomy. Our objective was to characterize the execution of the Bariatric Surgery Bundled Payment Program in its first year of implementation. Methods Descriptive and observational study of the pragmatic approach of the national execution of the payment associated with diagnosis in bariatric surgery. We examined sociodemographic variables (sex, age brackets, and National Health Fund tranches) and characterization of surgeries by code broken down by public or private provider, period of issue, unit cost, co-payment, and medical loans between March and December 2022. Results We recorded n = 13 118 surgeries (45.81% bypass versus 54.19% sleeve), of which n = 2424 (18.48%) used medical loans.

Private providers performed a total of 99.21% of the surgeries. Ten accounted for 50% of the activity (range n = 1200 to 426 surgeries per year; n = 4.8 to 1.7 surgeries per working day). Total program expenditure was $71 626 948 350 CLP, accounting for 5.04% of the total activity of the national Diagnosis Associated Payment Program. Conclusions The implementation of this bariatric surgery voucher benefited more than 13 thousand people living with obesity, mostly women of productive ages and with purchasing capacity. As an equity strategy, regardless of the access route through the voucher, it will be important to safeguard the activity in the public network.

Mirtazapine as Appetite Stimulant in Patients With Non-Small Cell Lung Cancer and Anorexia: A Randomized Clinical Trial.

Importance: Currently there is no standard therapy to improve cancer-related anorexia, hampering survival. Mirtazapine has been suggested as a feasible option in this context. Objectives: To assess the effect of mirtazapine on appetite and energy consumption in patients with advanced non-small cell lung cancer (NSCLC). Design, Setting, and Participants: This randomized, double-blind, placebo-controlled clinical trial including adults was performed in a tertiary cancer care center from August 2018 to May 2022 with a follow-up of 8 weeks. Overall, 134 patients were screened; 114 were assessed for eligibility and 28 were excluded. Interventions: Patients were randomized in a 1:1 ratio to receive mirtazapine, 15 mg, or placebo for 2 weeks followed by a dose escalation to 30 mg until week 8 or placebo. Both groups received nutritional assessment and dietary advice. Main outcomes and measures: Appetite was assessed by the Anorexia Cachexia Scale and energy intake. Dietary parameters were evaluated at baseline, 4 weeks, and 8 weeks, with a 24-hour dietary recall, and energy quantification based on the Mexican system of nutritional equivalents. Results: A total of 86 patients met the inclusion criteria and were randomized to the placebo (n = 43) or the mirtazapine group (n = 43). The mean (SD) age was 63.5 (11.2) years, 41 were women (57.7%) and had adenocarcinoma, Eastern Cooperative Oncology Group performance status scale score of 1, stage IV NSCLC, and were receiving first-line treatment. Baseline characteristics were similar between groups. There was no difference in appetite scores in patients who received mirtazapine or placebo after 4 and 8 weeks. After 4 weeks, mirtazapine significantly increased energy intake (379.3 kcal; 95% CI, 1382.6-576.1; P < .001) including proteins (22.5 g; 95% CI, 11.5-33.4; P = .001), carbohydrates (43.4 g; 95% CI, 13.1-73.8; P = .006), and fats (13.2 g; 95% CI, 6.0-20.4; P = .006). Fats intake was significantly higher in patients in the mirtazapine group (14.5 g vs 0.7 g; P = .02) after 8 weeks. The mirtazapine group significantly decreased the proportion of patients with sarcopenia (82.8% vs 57.1%, P = .03) at 8 weeks. Patients on mirtazapine tolerated the treatment well, but reported a higher perception of nightmares at 2 weeks based on a 10 cm VAS score (0 [25th-75th percentile, 0-1] vs 0 [25th-75th percentile, 0-0] in the control group; P = .009) but this finding was nonsignificant after 4 and 8 weeks. Conclusion and Relevance: In this randomized clinical trial of patients with advanced NSCLC, there was no difference in appetite scores in all patients who received mirtazapine or placebo, but the mirtazapine group had a significant increase in energy intake through the 4- and 8-week follow-up, mainly in fat intake, which is a better and crucial source of energy. The addition of mirtazapine in the treatment of patients with advanced NSCLC and anorexia may help these patients achieve their energy requirements and improve health-related quality of life, specifically emotional and cognitive functioning.

Barriers and Best Practices on the Management of Opioid Use Disorder.

Opioids refer to chemicals that agonize opioid receptors in the body resulting in analgesia and sometimes, euphoria. Opiates include morphine and codeine; semi-synthetic opioids include heroin, hydrocodone, oxycodone, and buprenorphine; and fully synthetic opioids include tramadol, fentanyl and methadone. In 2021, an estimated 5.6 million individuals met criteria for opioid use disorder. This article provides an overview of the pharmacology of heroin and non-prescription fentanyl (NPF) and its synthetic analogues, and summarizes the literature related to the management of opioid use disorder, overdose, and withdrawal. This is followed by a description of barriers to treatment and best practices for management with a discussion on recent updates and their potential impact on this patient population.

Liquid biopsy in clinical outcomes and detection of T790M mutation in metastatic non-small cell lung cancer after progression to EGFR-TKI.

BACKGROUND: Liquid biopsy (LB) is used to detect epidermal growth factor receptor (EGFR) mutations in non-small cell lung cancer (NSCLC) and has been demonstrated to have prognostic and predictive value. OBJECTIVE: To associate the rates of EGFR and T790M mutations detected by LB during disease progression after first- or second-generation EGFR-TKIs with clinical characteristics and survival outcomes. METHODS: From January 2018 to December 2021, 295 patients with advanced EGFR mutant (EGFRm) NSCLC treated with first- or second-generation EGFR-TKIs were retrospectively analyzed. LB was collected at the time of progression. The frequency of EGFRT790M mutations, overall survival (OS), and the clinical characteristics associated with LB positivity were determined. RESULTS: The prevalence of EGFRT790M mutation detected using LB was 44%. In patients with negative vs. positive LB, the median OS was 45.0 months vs. 25.0 months (p= 0.0001), respectively. Patients with a T790M mutation receiving osimertinib had a median OS of 44 months (95% CI [33.05-54.99]). Clinical characteristics associated with positive LB at progression extra-thoracic involvement, > 3 metastatic sites, and bone metastases. CONCLUSIONS: Our findings showed that LB positivity was associated with worse survival outcomes and specific clinical characteristics. This study also confirmed the feasibility and detection rate of T790M mutation in a Latin American population.

Increased epithelial mTORC1 activity in chronic rhinosinusitis with nasal polyps.

Background: The airway epithelium plays a central role in the pathogenesis of chronic respiratory diseases such as asthma and chronic rhinosinusitis with nasal polyps (CRSwNP), but the mechanisms by which airway epithelial cells (EpCs) maintain inflammation are poorly understood. Objective: We hypothesized that transcriptomic assessment of sorted airway EpCs across the spectrum of differentiation would allow us to define mechanisms by which EpCs perpetuate airway inflammation. Methods: Ethmoid sinus EpCs from adult patients with CRS were sorted into 3 subsets, bulk RNA sequenced, and analyzed for differentially expressed genes and pathways. Single cell RNA-seq (scRNA-seq) datasets from eosinophilic and non-eosinophilic CRSwNP and bulk RNA-seq of EpCs from mild/moderate and severe asthma were assessed. Immunofluorescent staining and ex vivo functional analysis of sinus EpCs were used to validate our findings. Results: Analysis within and across purified EpC subsets revealed an enrichment in glycolytic programming in CRSwNP vs CRSsNP. Correlation analysis identified mammalian target of rapamycin complex 1 (mTORC1) as a potential regulator of the glycolytic program and identified EpC expression of cytokines and wound healing genes as potential sequelae. mTORC1 activity was upregulated in CRSwNP, and ex vivo inhibition demonstrated that mTOR is critical for EpC generation of CXCL8, IL-33, and CXCL2. Across patient samples, the degree of glycolytic activity was associated with T2 inflammation in CRSwNP, and with both T2 and non-T2 inflammation in severe asthma. Conclusions: Together, these findings highlight a metabolic axis required to support epithelial generation of cytokines critical to both chronic T2 and non-T2 inflammation in CRSwNP and asthma.

Management of diarrhea induced by EGFR-TKIs in advanced lung adenocarcinoma.

The identification of Epidermal Growth Factor Receptor (EGFR) mutations in lung adenocarcinoma has facilitated the development of personalized medicine based on oncogenic drivers. EGFR-Tyrosine Kinase Inhibitors (TKIs) are part of the targeted therapy; they impede the phosphorylation of the intracellular tyrosine kinase component of EGFR and consequently block signal transduction pathways. These drugs inhibit the proliferation and survival of tumor cells, leading to long-term progression-free survival and overall survival. Diarrhea is one of the most frequent adverse events associated with EGFR-TKIs, affecting at least 18% of patients and reaching up to 95% in some cases. Diarrhea should be managed carefully given its association with important complications, treatment interruptions, and dose reductions. Moreover, nutritional status and quality of life (QoL) can deteriorate due to severe diarrhea. Changes in diet, such as increment of fiber, supplementation with glutamine, and use of probiotics, may contribute to a decrease in the incidence of diarrhea. Improving the control of diarrhea can provide a significant benefit to the QoL of patients.

Research Mapping of Trauma Experiences in Autism Spectrum Disorders: A Bibliometric Analysis.

The number of research related to traumatic experiences in people with autism spectrum disorder (ASD) has grown exponentially, yet there are no bibliometric studies in this field. This article aimed to analyze the literature related to trauma and ASD published in Web of Science (WoS). Papers on trauma and ASD were retrieved from the WoS. Analysis and visualization of selected documents were performed using MS Excel (v16.0), VOS viewer (version 1.6.15), and R package (Biblioshiny, version 2.0). A total of 147 articles were included in this study. The results showed that production has been increasing over the last few years. Among the countries identified, the USA published the largest number of articles. Arvid Nikolai Kildahl, Sissel Berge Helverschou, and Liliana Dell'Osso were the authors with the most number of publications on this topic, and Autism was the most productive journal. The main research topics associated with ASD were post-traumatic stress and traumatic experiences in childhood. This bibliometric study contributes to understanding research trends on trauma and ASD by evaluating relevant publications in the last decades. The results of this bibliometric analysis can serve as a basis and orientation for new studies.

Gender expectations, socioeconomic inequalities and definitions of career success: A qualitative study with university students.

Higher Education (HE) is seen as a tool to create job opportunities and enhance individuals' quality of life. Research demonstrates that students' expectations of career success in HE are an important predictor of their motivation and academic attainment. However, there is a lack of clarity about how career success is defined and whether individuals perceive that their experiences (e.g., gender) may be associated with these definitions. In online written interviews with 36 university students in the United Kingdom, we examine how students define career success and how they perceive their identity (gender, socioeconomic status) experiences underpinning these definitions. We analysed three main definitional themes: (a) career success as personal development, (b) career success as individual mobility, and (c) lack of clarity about what career success is. Findings suggest that gender and socioeconomic experiences had an important role in students' understanding of career success, especially for students from disadvantaged backgrounds. Indeed, in the intersection of gender and socioeconomic status, inequalities persist: female students anticipated difficulties in terms of work-life balance and gender stereotypes that constrained their career success definitions. Moreover, family experiences were important to understand students' definitions of career success, particularly for disadvantaged socioeconomic groups. The current research sheds light on an important paradox in HE organisations: while students tend to define career success in relatively individualistic ways, such as individual mobility, financial success, or personal development, it was clear that their social identities (e.g., gender, socioeconomic status) and related experiences played an important role in creating definitions of career success. This further implies that when universities encourage a perception of career success as individual mobility, for example, having better job opportunities, or by espousing the belief that higher education and/or professional sectors are truly meritocratic-this will not always align with, and may create tension for, students from disadvantaged groups.

Gender and social class inequalities in higher education: intersectional reflections on a workshop experience.

Research about the experiences of underrepresented groups in higher education (HE) demonstrates the persistence of challenges, despite policies and institutional strategies to promote inclusion. Diversity and inclusion policies have been part of the HE agenda for several decades, yet most policies and interventions focus on (a) a given, isolated identity experience (e.g., based solely on gender, social class, or ethnicity) rather than more intersectional approaches to identity; and (b) top-down interventions that do not include participants insights in their design. In this paper, we report a case study of a workshop with students at an elite university that drew on an intersectional approach to social identities (IASI), specifically, looking at gender and social class. We explore three key themes: (a) the importance of group processes, (b) the use of visual techniques, and (c) the institutional tensions and the (de)politicisation of social psychology research. Reflecting on this case study we argue that approaches to identity and inclusion in HE can benefit from intersectionality beyond the use of multi and overlapping identity and social group categories. We argue that research in this space is not neutral and needs to acknowledge researchers' position about (a) inclusion and diversity, (b) perceptions of participants in research, and (c) the motivation and aims of institutions where the research is conducted. Finally, we discuss the theoretical and practical implications of integrating an intersectional approach within social identity research in HE when focusing on underrepresented groups.

Tamizaje para cáncer de mama con resonancia magnética en mujeres portadoras de mutaciones BRCA y no-BRCA / Magnetic resonance imaging breast cancer screening in women who are carriers of BRCA and non-BRCA gene mutations / Rastreamento de câncer de mama com ressonância magnética em mulheres com mutações BRCA e não BRCA

Introducción: la predisposición hereditaria causada por mutaciones patogénicas de la línea germinal (MPG) explica hasta el 10% de los cánceres de mama. Para reducir su impacto en mujeres mutadas se han propuesto diferentes estrategias, tales como las cirugías reductoras de riesgo o el screening con resonancia magnética (RM) de mamas. Métodos: en este estudio observacional retrospectivo se analizaron los registros de mujeres portadoras de MPG para evaluar las diferentes acciones tomadas luego del test genético. A las pacientes no mastectomizadas se les recomendó ingresar a un programa anual de cribado con RM y se evaluó el porcentaje de adherencia al plan, el número de biopsias efectuadas y el número de cánceres de mama detectados. Resultados: se incluyeron 134 mujeres con MPG, con una distribución en tercios iguales de los genes BRCA1, BRCA2 y genes no-BRCA. Entre las mutadas con indicación de seguimiento, 64% ingresaron al programa de cribado con RM. Las razones que llevaron a las mujeres a no ingresar al programa de seguimiento fueron: la oposición del médico tratante (53%), oposición de la paciente (38%), y falta de recursos (9%). Se realizaron seis biopsias por hallazgos en la RM entre las cuales se detectó un cáncer de mama. La incidencia de cáncer fue de 11 cada 1.000 mujeres-años de riesgo. Conclusiones: nuestro programa de seguimiento con RM de pacientes mutadas logró captar un porcentaje alto de candidatas. Una proporción significativa de las mujeres no ingresó debido la desaprobación del médico tratante o de la propia paciente. La evidencia obtenida revela una necesidad imperiosa de reforzar los programas educativos que destaquen la importancia del seguimiento con RM de las pacientes de alto riesgo en nuestro país.

Summary: Introduction: genetic propensity caused by germline pathogenic mutations explain up to 10% of breast cancer cases. Different strategies have been proposed to reduce its impact on women who are carriers of mutations, such as risk-reducing surgeries or breast magnetic resonance screening. Method: observational, retrospective study analyzing the medical records of women who are carriers of germline pathogenic mutations to assess the different measures taken after the genetic test. Non-mastectomized patients were advised to join an annual MRI screening program and the percentage of adherence to plan was evaluated, along with biopsies performed and the number of breast cancer cases detected. Results: 134 women carriers of germline pathogenic mutations were included in the study, with equal distributions in thirds for BRCA1, BRCA2 and non-BRCA genes. 64% of carriers of mutations who were subject to follow-up checkups joined the RMI screening program. The reasons why women failed to join the follow-up program were: the treating physician objected to the program (53%), the patients opposed to program (38%) and lack of resources (9%). Six biopsies were performed as a consequence of findings in the RMI, and one case of breast cancer was detected. Cancer incidence was 11 out of 1000 women - risk years. Conclusions: our RMI follow-up program for women who are carriers of mutations managed to attract a high percentage of candidates. A significant amount of women failed to join the program because of their treating physician's or their own disapproval. Evidence obtained reveals the dramatic need to reinforce educational programs that emphasize on the importance of RMI follow-up of high risk patients in our country.

Introdução: a predisposição hereditária causada por mutações germinativas patogênicas (GMP) explica até 10% dos cânceres de mama. Para reduzir seu impacto em mulheres com mutações, diferentes estratégias têm sido propostas, como cirurgias de redução de risco ou ressonância magnética (RM) das mamas. Métodos: neste estudo observacional retrospectivo, os registros de mulheres portadoras de MPG foram analisados para avaliar as diferentes ações tomadas após o teste genético. Pacientes não mastectomizadas foram recomendadas a entrar em um programa anual de triagem por ressonância magnética e foram avaliados o percentual de adesão ao plano, o número de biópsias realizadas e o número de cânceres de mama detectados. Resultados: foram incluídas 134 mulheres com MPG, com uma distribuição de terços iguais dos genes BRCA1, BRCA2 e não-BRCA. Entre as mulheres com mutações com indicação de acompanhamento, 64% entraram no programa de triagem por ressonância magnética. Os motivos que levaram as mulheres a não ingressarem ao programa de acompanhamento foram: oposição do médico assistente (53%), oposição da paciente (38%) e falta de recursos (9%). Seis biópsias foram realizadas devido a achados de ressonância magnética, entre os quais foi detectado um câncer de mama. A incidência de câncer foi de 11 por 1.000 mulheres-ano de risco. Conclusões: nosso programa de acompanhamento de ressonância magnética para pacientes com mutação conseguiu capturar uma alta porcentagem de candidatas. Uma proporção significativa de mulheres não entrou devido à falta de aprovação do médico assistente ou da própria paciente. As evidências obtidas revelam a necessidade urgente de reforçar programas educacionais que destaquem a importância do acompanhamento por RM de pacientes de alto risco no Uruguai.

Mechanical Thrombectomy for Acute Ischemic Stroke Due to Large Vessel Occlusion in Argentina: An Economic Analysis.

OBJECTIVES: Mechanical thrombectomy (MT) after intravenous thrombolysis (IV-tPA) is an effective and cost-saving treatment for stroke due to large vessel occlusion. However, rates of MT use are low in Argentina. This study was designed to estimate the economic value and the budget impact of incorporating MT after thrombolysis, simulating scenarios from Argentinian compulsory social health insurance (Obras Sociales) and private insurances (Empresas de Medicina Prepaga). MATERIALS AND METHODS: We adapted a previously published cost-utility and budget-impact (CUA and BIA) model to the Argentinian setting. The CUA was carried out for a lifetime horizon with efficacy inputs from the SWIFT PRIME clinical trial. For seven possible health states, we identified local costs (Argentinian Pesos AR$), utility (QALY), and transition/distribution probabilities (5% discounted rate) and performed deterministic and probabilistic sensitivity analyses. The BIA was based on a six-step approach and a static model for a five-year horizon, and two scenarios (staggered growth and no growth). RESULTS: Despite higher incremental procedure costs, IV-tPA and MT was dominant over IV-tPA alone (AR$1,049,062 overall savings). Cost-effectiveness remained in the deterministic sensitivity analysis (100% probability of cost-effectiveness). Increased MT procedure volume resulted in savings in years three (0.96%), four (2.6%), and five (4.4%). By year five, 1,280 patients were treated with MT (versus 480) with overall savings of 1.8% (AR$817,244,417). CONCLUSIONS: MT after IV-tPA is cost-effective in Argentina. Savings offset the incremental hospitalization and long-term costs from the third year onwards. With increased, access the superior efficacy of MT mitigates future disability and comorbidity, reducing overall expenses.

Appetite stimulants for patients with cancer: current evidence for clinical practice.

The incidence of neoplastic diseases has increased worldwide, with an estimated global burden of 19.3 million incident cases and 10 million deaths in 2020-a considerable increase compared with 9.6 million deaths in 2018. One of the most prevalent problems faced by patients with cancer and their physicians is malnutrition. It is estimated that patients with cancer have important nutritional alterations in 25% to 70% of cases, which directly affects many spheres of patient care and well-being, including quality of life, treatment toxicity, and survival outcomes. Despite the overwhelming need to address this pressing issue, current evidence in terms of pharmacologic interventions for cancer-related anorexia remains inconclusive, and there is no current standard of care for patients with cancer-related anorexia. Nonetheless, international guidelines recommend promoting anabolism through nutritional, physical, and pharmacologic therapies. In this review, the available information is summarized regarding pharmacologic therapies to treat cancer-related anorexia and findings are highlighted from a clinical stance.

Womens access to health care: Gaps that the future health care reform in Chile must solve. / Acceso de la mujer a la atención de salud: brechas que la futura reforma de salud en Chile debe resolver.

INTRODUCTION: In the Chilean health system, difficulties complicate womens access to health care and aggravate the complexity of health-illness processes in their interaction as users or caregivers. OBJECTIVE: In the national and international literature, we aimed to identify gaps in womens access to health care derived from gender disparities and the exercise of gender roles in a prioritized set of health problems. These problems exacerbate gender gaps and should be considered in health reform. METHODS: We made a literature review through algorithms, snowball sampling, and reference lists from November 2020 to March 2021. The population included were women of all ages, including women users of the health system and women caregivers of specific pathologies. The search was conducted in parallel by four investigators divided into two groups. It was cross-validated to ensure inter-investigator reliability by standardizing evidence eligibility criteria. The analysis showed women users' and caregivers' dimensions for a set of pathologies prioritized by the extent of the disease burden. The pathologies analyzed included stroke, obesity, depression, musculoskeletal pain, and breast cancer. RESULTS: Among women users of the health system, problems of access, rates of use, experience, and outcome for the whole group of prioritized pathologies were observed. In the women caregiver dimension, we found that women are the primary health care providers. There is a knowledge gap concerning obesity and musculoskeletal conditions. However, both were reported as health consequences of womens caregiving roles.

INTRODUCCIÓN: En el sistema de salud chileno persisten dificultades que complejizan el acceso de mujeres de forma efectiva a las atenciones de salud, o bien, derivan en que experimenten procesos de salud-enfermedad más complejos en su interacción como usuarias o cuidadoras. OBJETIVO: Identificamos en la literatura nacional e internacional, brechas de acceso a la atención de salud en la mujer derivadas de disparidades de género y/o ejercicio del rol de género, en un conjunto priorizado de problemas de salud. Estos problemas contribuyen a la problematización de las brechas de género a ser consideradas en la reforma de salud. MÉTODOS: Hicimos una revisión de la literatura a través de algoritmos, muestreo en bola de nieve y listas de referencias, desde noviembre de 2020 hasta marzo de 2021. La población de análisis fueron mujeres de todas las edades usuarias de prestaciones de salud y cuidadoras en las mismas patologías abordadas. La búsqueda fue desarrollada en paralelo por cuatro investigadores, en dos grupos. Fue validada de forma cruzada asegurando la confiabilidad interevaluadores, estandarizando criterios de elegibilidad de la evidencia. El análisis se muestra en dimensiones de mujer usuaria y cuidadora, para un conjunto de patologías priorizadas por magnitud y carga de enfermedad: accidente vascular cerebral, obesidad, depresión, dolor musculoesquelético y cáncer de mama. RESULTADOS: En la dimensión de mujer usuaria, para todo el grupo de patologías priorizadas se observan problemas de acceso, tasas de uso, experiencia y resultados. Desde la dimensión de mujer cuidadora, la mujer ejerce principalmente los cuidados de salud. Existe un vacío en la literatura en relación con la obesidad y afecciones musculoesqueléticas. Sin embargo, ambas se reportaron como consecuencias de salud en su rol de cuidadora. CONCLUSIONES: El problema en la base, en ambas dimensiones, queda explicado por brechas de género biológicas, sociales y culturales que permean el ámbito de cuidados sanitarios. Proponer una nueva reforma de salud que solo se funde en la proposición de acceso a más prestaciones, es insuficiente de acuerdo con el contexto biopsicosocial de la mujer.

[Cost-utility analysis: Mechanical thrombectomy plus thrombolysis in ischemic stroke due to large vessel occlusion in the public sector in Chile]. / Análisis de costo utilidad: trombectomía mecánica más trombólisis en accidente vascular cerebral isquémico debido a oclusión de grandes vasos en el sector público en Chile.

INTRODUCTION: Several studies demonstrate the therapeutic superiority of thrombolysis plus mechanical thrombectomy versus thrombolysis alone to treat stroke. OBJECTIVE: To analyze the cost-utility of thrombolysis plus mechanical thrombectomy versus thrombolysis in patients with ischemic stroke due to large vessel occlusion. METHODS: Cost-utility analysis. The model used is blended: Decision Tree (first 90 days) and Markov in the long term, of seven health states based on a disease-specific scale, from the Chilean public insurance and societal perspective. Quality-Adjusted Life-Years and costs are evaluated. Deterministic (DSA) and probabilistic (PSA) analyses were carried out. RESULTS: From the public insurance perspective, in the base case, mechanical thrombectomy is associated with lower costs in a lifetime horizon, and with higher benefits (2.63 incremental QALYs, and 1.19 discounted incremental life years), at a Net Monetary Benefit (NMB) of CLP 37,289,874, and an Incremental Cost-Utility Ratio (ICUR) of CLP 3,807,413/QALY. For the scenario that incorporates access to rehabilitation, 2.54 incremental QALYs and 1.13 discounted life years were estimated, resulting in an NMB of CLP 35,670,319 and ICUR of CLP 3,960,624/QALY. In the scenario that incorporates access to long-term care from a societal perspective, the ICUR falls to CLP 951,911/QALY, and the NMB raises to CLP 43,318,072, improving the previous scenarios. In the DSA, health states, starting age, and relative risk of dying were the variables with the greatest influence. The PSA for the base case corroborated the estimates. CONCLUSIONS: Thrombolysis plus mechanical thrombectomy adds quality of life at costs acceptable for decision-makers versus thrombolysis alone. The results are consistent with international studies.

INTRODUCCIÓN: Diversos estudios demuestran la superioridad terapéutica de la trombólisis más trombectomía mecánica, versus trombólisis sola, en el tratamiento del accidente vascular cerebral. OBJETIVOS: Analizar el costo utilidad de la trombólisis más trombectomía versus trombólisis sola en pacientes con accidente vascular cerebral isquémico con oclusión de grandes vasos. MÉTODOS: Evaluación de costo utilidad. Se ha utilizado un modelo mixto: árbol de decisión (primeros 90 días) y Markov en el largo plazo, de siete estados de salud definidos en escala específica de enfermedad, desde la perspectiva del seguro público chileno y societal. Se evalúan costos y años de vida ajustados por calidad. Se realizó análisis de incertidumbre determinístico y probabilístico. RESULTADOS: Bajo la perspectiva de seguro público, en el caso base la trombectomía mecánica se relaciona con menores costos en un horizonte de por vida, con mayores beneficios (2,63 años de vida ajustados por calidad incrementales, y 1,19 años de vida incrementales descontados), a un beneficio monetario neto de $37 289 874 pesos chilenos, y una razón incremental de costo utilidad de $3 807 413 pesos por años de vida ajustados por calidad. Para el escenario que agrega acceso a rehabilitación se estimaron 2,54 años de vida ajustados por calidad incremental y 1,13 años de vida descontados, resultando en un beneficio monetario neto de $35 670 319 pesos y razón incremental de costo utilidad de $3 960 624 pesos por años de vida ajustados por calidad. En el escenario que agrega el efecto de acceso a cuidados de larga duración con perspectiva societal, la razón incremental de costo utilidad cae hasta $951 911 pesos por años de vida ajustados por calidad y el beneficio monetario neto se eleva a $43 318 072 pesos, superando las estimaciones anteriores. En el análisis de incertidumbre determinístico, los estados de salud, edad de inicio de la cohorte y riesgo relativo de morir, fueron las variables con mayor influencia. El análisis de incertidumbre probabilístico para el caso base, corroboró las estimaciones. CONCLUSIONES: La trombólisis más trombectomía mecánica agrega calidad de vida a costos aceptables por el tomador de decisión, versus trombólisis sola. Los resultados son consistentes con los estudios internacionales.

[Economic evaluation in health: Cost-utility of the incorporation of total knee replacement to the Chilean Explicit Health-Guarantees regime]. / Evaluación económica en salud: costo-utilidad de la incorporación del reemplazo total de rodilla en la cobertura del régimen de Garantías Explícitas en Salud en Chile.

BACKGROUND: Osteoarthritis is an important health condition due to its prevalence and functional deterioration, being the most common cause of disability in people over 65 years of age. The Chilean Explicit Health-Guarantees regime provides coverage for medical treatment in mild and moderate presentations, excluding surgical treatment in end-stage knee osteoarthritis. OBJECTIVES: To evaluate the cost-utility of incorporating total knee replacement to the Explicit Health-Guarantees regime for over-65-years beneficiaries of the public insurance system, versus maintenance with medical treatment. METHODS: A Scoping review was coducted to identify model parameters and economic evaluation based in a 6 health states Markov Model, from the perspective of the public payer and lifetime horizon. The Incremental Cost-Utility Ratio (ICUR) was calculated, and deterministic and probabilistic uncertainty analysis were performed. RESULTS: Twenty-two articles were selected as reference sources. If the regime were to adopt the procedure, the implication would be a benefit of 9.8 Years of Life Adjusted by Quality (QALY) versus 2.4 QALY in the scenario without access to total knee replacement. The ICUR was $ -445 689 CLP/QALY (U$D -633.8/QALY), wherein the inclusion of total knee replacement to the regime becomes a dominant alternative versus the current scenario. Each quality-adjusted life-year gained by the surgery will save CLP 445 689. At a willingness to pay of CLP 502,596/QALY (U$D 714.7/QALY), access to surgery is cost-useful with a 99.9% certainty. CONCLUSION: Total knee replacement in patients older than 65 years is a dominant alternative. Access to this procedure in the Chilean Explicit Health-Guarantees regime in the public system is cost-useful at a threshold of 1 GDP per capita.

ANTECEDENTES: La osteoartritis destaca por su alta prevalencia y deterioro funcional, siendo la causa más común de incapacidad en mayores de 65 años. El régimen de Garantías Explícitas en Salud chileno otorga cobertura a tratamiento médico a las presentaciones leves y moderadas, excluyendo el manejo quirúrgico en la presentación severa. OBJETIVOS: Evaluar el costo-utilidad de incorporar el reemplazo total de rodilla al régimen de Garantías Explícitas en Salud para asegurados del seguro público sobre 65 años en Chile, versus la mantención con manejo farmacológico. MÉTODOS: Revisión sistemática explortaria para identificar los parámetros del modelo y evaluaciones económicas basadas en un modelo de Markov de seis estados de salud, desde la perspectiva del pagador público y horizonte lifetime. Se calculó la razón de costo-utilidad incremental que condujo al análisis de incertidumbre determinístico y probabilístico. RESULTADOS: Se seleccionaron 22 artículos como fuentes de referencia. Incorporar el procedimiento al alero del régimen, implicaría beneficiarse de 9,8 años de vida ajustados por calidad versus 2,4 en el escenario sin acceso a cirugía. La razón de costo-utilidad incremental es menos $445 689 pesos chilenos por años de vida ajustados por calidad (menos 633,8 dólares americanos por años de vida ajustados por calidad), siendo la incorporación de cirugía de reemplazo al régimen una alternativa dominante, versus el escenario de acceso insuficiente en otros regímenes de cobertura. Cada año de vida ajustado por calidad gracias a la cirugía ahorrará $445 689 pesos chilenos. A una voluntad de pago de $502 596 pesos chilenos por años de vida ajustados por calidad (714,7 dólares americanos por años de vida ajustados por calidad), la alternativa de acceso a reemplazo es costo-útil con 99,9% de certeza. CONCLUSIÓN: El reemplazo total de rodilla en mayores de 65 años es una alternativa dominante. El acceso a cirugía en el régimen de Garantías Explícitas en Salud para el sistema público es costo-útil a un umbral de un producto interno bruto per cápita.

Trasplante facial generalidades / Facial trasplant generalities

Resumen El trasplante facial es un alotrasplante compuesto vascularizado que busca la reconstrucción de defectos masivos faciales permitiendo la reinserción social del receptor, generando un impacto positivo sobre su calidad de vida. El objetivo de este artículo fue realizar una revisión de la literatura sobre generalidades del trasplante facial, enfocándose en los cuidados pre, intra y postoperatorios concernientes a la temática. La búsqueda bibliográfica se realizó desde el 13 de septiembre del 2018 hasta el 31 de marzo del 2019 utilizando los términos MESH "Face Transplant" y "Face Transplantation". Aplicando los criterios de inclusión y exclusión se obtuvieron 43 artículos sobre los cuales se desarrolló la revisión. El trasplante facial es un procedimiento nuevo en el cual hay muchas áreas por explorar, sin embargo, es una alternativa prometedora a los métodos utilizados para la reconstrucción de lesiones faciales complejas, que se optimizará a medida que se extienda su uso. MÉD.UIS.2020;33(3): 29-36

Abstract The facial transplant is a vascularized compound allogeneic transplant that seeks the reconstruction of massive facial defects allowing the social reintegration of the recipient, generating a positive impact on their quality of life. The objective of this article was to review the literature on generalities of facial transplantation, focusing on the pre, intra and postoperative care regarding the subject. The bibliographic search was performed from September 13, 2018 to March 31, 2019 using the MESH terms "Face Transplant" and "Face Transplantation". Applying the inclusion and exclusion criteria, 43 articles were obtained on which the review was developed. Facial transplantation is a new procedure in which there are many areas to explore, however, it is a promising alternative to the methods used for the reconstruction of complex facial injuries, which will be optimized as its use expands.
