ABSTRACT Livestock systems at Region Aysén del General Carlos Ibáñez del Campo depend on forage conservation during the spring-summer season, generally with low nutritional quality to animal requirements. To reduce nutrient loss, additives are commonly used, being spent brewery yeast a potential additive. Therefore, a study was carried out with the inclusion of two spent brewer’s yeast (Lager and Ale) as an additive in pasture mini silos compared to two commercial additives (SiloSolve MC™ and Josilac grass™) and mini silo without additive. It was observed that spent brewer’s yeast has a negative effect on crude protein and metabolizable energy, contents that decreased to 9.8% and 2.5%, respectively, compared to control. However, Ale yeast declined faster and maintained lower pH levels below 4.1. Spent brewer’s yeast do not improve nutritional quality, however decreased pH levels of pasture silage. Therefore, it should be noted that the effect of spent brewer’s yeasts has been insufficiently evaluated. Thus, is still a lack of trials within large scale of silage conservation and its effects on animal feed performance.

Background: Long-term outcomes of Off-Pump Coronary Artery Bypass Grafting (OPCAB) as an alternative to the traditional Coronary Artery Bypass Grafting (CABG) technique with cardiopulmonary bypass (CPB) are not well defined. Aim: To compare 10-year survival of isolated OPCAB versus CABG with CPB. Material and Methods: Analysis of information obtained from databases, clinical records and surgical protocols of patients treated with isolated CABG between January 2006 and November 2008 at a Regional Hospital. Of 658 isolated CABG, 192 (29.2%) were OPCAB and 466 (79.9%) CPB. Propensity Score Matching (PSM) was performed to compare both groups. After PSM, two groups of 192 cases were obtained. Mortality data was obtained from the Chilean public identification service. Ten-year survival was calculated and compared with Kaplan-Meier and log-rank methods. Results: Follow-up data was obtained in all cases. No statistically significant differences were found when comparing 10-year survival between OPCAB versus CPB (78.6% and 80.2% respectively, p 0.720). There was also no statistical difference in cardiovascular death free survival (90.1% with CPB versus 89.1% OPCAB, p 0.737). Survival was comparable when analyzing subgroups with diabetes mellitus, left ventricular dysfunction or chronic kidney disease, among others. Conclusions: In our series, OPBAB has a comparable 10-year survival with CABG with CPB.

Abstract Background Despite representing the largest fraction of animal life, the number of insect species whose genome has been sequenced is barely in the hundreds. The order Dermaptera (the earwigs) suffers from a lack of genomic information despite its unique position as one of the basally derived insect groups and its importance in agroecosystems. As part of a national educational and outreach program in genomics, a plan was formulated to engage the participation of high school students in a genome sequencing project. Students from twelve schools across Chile were instructed to capture earwig specimens in their geographical area, to identify them and to provide material for genome sequencing to be carried out by themselves in their schools. Results The school students collected specimens from two cosmopolitan earwig species: Euborellia annulipes (Fam. Anisolabididae) and Forficula auricularia (Fam. Forficulidae). Genomic DNA was extracted and, with the help of scientific teams that traveled to the schools, was sequenced using nanopore sequencers. The sequence data obtained for both species was assembled and annotated. We obtained genome sizes of 1.18 Gb (F. auricularia) and 0.94 Gb (E. annulipes) with the number of predicted protein coding genes being 31,800 and 40,000, respectively. Our analysis showed that we were able to capture a high percentage (≥ 93%) of conserved proteins indicating genomes that are useful for comparative and functional analysis. We were also able to characterize structural elements such as repetitive sequences and non-coding RNA genes. Finally, functional categories of genes that are overrepresented in each species suggest important differences in the process underlying the formation of germ cells, and modes of reproduction between them, features that are one of the distinguishing biological properties that characterize these two distant families of Dermaptera. Conclusions This work represents an unprecedented instance where the scientific and lay community have come together to collaborate in a genome sequencing project. The versatility and accessibility of nanopore sequencers was key to the success of the initiative. We were able to obtain full genome sequences of two important and widely distributed species of insects which had not been analyzed at this level previously. The data made available by the project should illuminate future studies on the Dermaptera.

Abstract Objectives The present study aimed to evaluate the measurement invariance of a general measure of the perception of governmental responses to COVID-|19 (COVID-SCORE-10) in the general population of 13 Latin American countries. Methods A total of 5780 individuals from 13 Latin American and Caribbean countries selected by non-probabilistic snowball sampling participated. A confirmatory factor analysis was performed and the alignment method was used to evaluate invariance. Additionally, a graded response model was used for the assessment of item characteristics. Results The results indicate that there is approximate measurement invariance of the COVID-SCORE-10 among the participating countries. Furthermore, IRT results suggest that the COVID-SCORE-10 measures with good psychometric ability a broad spectrum of the construct assessed, especially around average levels. Comparison of COVID-SCORE-10 scores indicated that participants from Cuba, Uruguay and El Salvador had the most positive perceptions of government actions to address the pandemic. Thus, the underlying construct of perception of government actions was equivalent in all countries. Conclusion The results show the importance of initially establishing the fundamental measurement properties and MI before inferring the cross-cultural universality of the construct to be measured.

Background: The adoption of sanitary measures due to the SARS-CoV-2 pandemic hampered teaching and learning methods in medicine. Aim: To communicate the results of a wound suture training workshop, based on the Basic Procedural Skills Training methodology and adapted to the pandemic context. Material and Methods: One hundred fourteen students were randomized in small groups due to sanitary measures and trained with a modification of the Basic Procedural Skills Training methodology. An informed consent was obtained from every student. The suturing skills were evaluated before and after the intervention with “The Objective Structured Assessment Of Technical Skills” (OSATS) instrument. The perception of the workshop and the implementation of the COVID-19 prevention measures were also evaluated. Results: The students showed a statistically significant improvement after the intervention. In the OSATS verification list, the average score increased from 4.5 to 8.6 (p < 0.01). In the OSATS global scale, the average score increased from 13.0 to 25.3 (p < 0.01). The perception of the workshop and the prevention measures were well evaluated. Conclusions: Despite all the limitations of the pandemic context, we achieved a significant improvement after the intervention and a very good perception by the students.

Background: Coronary artery bypass grafting (CABG) is the treatment of choice for a broad spectrum of patients with coronary disease. Aim: To describe global survival and factors associated with lower long-term survival in patients operated with isolated CABG. Material and Methods: Analysis of a cohort of patients who underwent CABG between January 2006 and December 2008 at a public hospital. The database and operation records of 1.003 cardiac surgeries were reviewed. Of these, an isolated CABG was performed in 658 patients aged 62 ± 9 years including 516 male (78%). Survival data were obtained from the Chilean Civil Registry Office and a complete ten-year follow up was accomplished. Survival was analyzed with Kaplan-Meier method with log-rank test and Cox regression. Results: Operative mortality occurred in 13 patients (2%). Survival at 1, 3, 5 and 10 years was 97, 94, 91 and 76%, respectively. One, 3, 5 and 10-year free of cardiovascular death survival was 98, 97, 95 y 89%, respectively. Factors associated with long-term survival were chronic kidney disease in hemodialysis (Hazard ratio (HR) 7.9; 95% confidence intervals (CI) 4.6-13.6), chronic obstructive pulmonary disease (HR 2.3; 95% CI 1.4-3.7), chronic arterial occlusive disease (HR 2.2; 95% CI 1.4-3.4) and diabetes mellitus (HR 1.9; 95% CI 1.4-2.6). According to EuroSCORE, 10-year survival was 86, 75 and 62% (p < 0.01) in low, medium and high-risk patients, respectively. Conclusions: These patients had a 10-year survival comparable to large international series. Groups associated with lower 10-year survival were identified.

Resumen A mediados de 2020, Corea del Sur implementó la política llamada Korean New Deal (K-New Deal), que junto con enfrentar las consecuencias sociales negativas de la pandemia de la Covid-19, busca posicionar al país como líder en materias de crecimiento verde y digitalización de la economía. Esta política pública proyectada en cinco años se asemeja a los planes quinquenales, donde el Estado desarrollista definía el curso que debían tomar los conglomerados de empresas surcoreanas (chaebol) en la economía. Aplicando un enfoque mixto de alcance descriptivo a través del método de estudio de caso, mediante una metodología de investigación de tipo documental, utilizando diversas fuentes bibliográficas -incluyendo análisis de medios-, en este artículo se analiza el desarrollo sostenible en Corea del Sur aplicado a uno de los conglomerados económicos más importantes, denominado CJ Group (siglas de Cheil Jedang). La investigación permite concluir que el K-New Deal, como ejemplo de implementación de políticas de desarrollo sostenible, se perfilaría como un posible modelo a seguir en el contexto del crecimiento verde y la economía digital en la era post-Covid-19.

Abstract In mid-2020, South Korea launched the New Deal policy, which seeks to position the country as a leader in matters of green growth and digitization of the economy along with facing the negative social consequences of the Covid-19 pandemic. This public policy projected in five years resembles the five-year plans, where the State defined the course that the conglomerates of South Korean companies (chaebol) should take in the economy. This research is of a documentary type and reviews various bibliographic sources, including media analysis. Through a mixed approach of descriptive scope and case study method, we focus on the phenomenon of sustainable development in South Korea applied to CJ chaebol. The aim is to analyze the implications of the K-New Deal in green growth and digitization of the economy. We conclude that the K-New Deal can be a role model in the context of the digital economy in the post-Covid-19 era.

Background: Thoracic great vessel injuries in thoracic trauma (TTGVI) are a heterogeneous group of injuries with high morbimortality that constituting 0.3-10% of the findings in thoracic trauma (TT). Aim: To describe characteristics, treatments and variables associated with mortality in hospitalized patients with TTGVI. Methods: Observational-analytical study. Period January-1981 and December-2020. Review of prospective TT protocols and clinical records. TTGVI were classified according to American Association for the Surgery of Trauma (AAST), trauma severity index were calculated: Injury Severity Score (ISS), Revised Trauma Score Triage (RTS-T) and Trauma Injury Severity Score (TRISS). Univariate and multi- variate analysis was performed with calculation of Odds Ratio (OR) for variables associated with mortality. SPSS25® was used, with U Mann Whitney and chi-squared tests, as appropriate. Results: From a total of 4.577 TT in the period, 97 (2.1%) met the inclusion criteria. Males: 81 (91.8%), mean age: 32.3 ± 14.8 years. Penetrating TT: 65 (67.0%). Axillary-subclavian artery lesions in 39 (40.2%) and thoracic aorta in 31 (32.0%) were more frequent. AAST 5-6: 39 (40.2%). Invasive treatment: 87 (89.7%), of these, in 20 (20.6%) endovascular repair, 14 (14.4%) of thoracic aorta. Open surgery in 67 (69.1%). Mortality in 13 (13.4%), shock on admission was independently associated with mortality (OR 6.34) and ISS > 25 (OR 6.03). Conclusión: In our series, TTGVI were more frequent in axillary-subclavian vessels and thoracic aorta. Treatment was mainly invasive, with open surgery being the most frequent. Variables associated with mortality were identified.

Background: The treatment of choice for Pulmonary Hydatid Cys (PHC) is surgical resection. There is currently controversy about the superiority of surgery with capitonage (SC) versus surgery without it (SWC). Aim: To compare the results of conservative surgery with capitonnage and versus surgery without capitonnage using Propensity Score Matching (PSM). Materials and Method: A retrospective analytical study was carried out with patients with PHC treated surgically at the Guillermo Grant Benavente Hospital, Concepción, Chile, between January-1995 and December-2018. A PSM was performed with a 1:1 ratio. Results: Conservative surgery was done in 165 cases, 101 SC and 64 SWC. After matching, 53 SC and 53 SWC operated patients were obtained. No significant differences were observed in the presence of persistent air leak (9.4% vs11.3%, SC vs SWC respectively, p 0.75), empyema (3.8% vs 0%, p 0.49), days with pleurotomy (9.1 ± 8.9 vs 10.1 ± 10.7, p 0.39), nor days of postoperative stay (10.4 ± 9.0 vs 11.7 ± 11.9, p 0.22). Conclusión: The SWC demonstrated comparable results to the SC technique in the conservative surgical treatment of PHC.

Resumen Introducción: El tratamiento de elección del Quiste Hidatídico Pulmonar (QHP) es la resección quirúrgica. Actualmente, existe controversia sobre la superioridad de la cirugía con capitonaje (CC) versus la cirugía sin capitonaje (SC). Objetivo: Comparar los resultados de la cirugía conservadora CC y SC mediante Propensity Score Matching (PSM). Materiales y Método: Se realizó un estudio analítico retrospectivo de los pacientes con QHP tratados quirúrgicamente en el Hospital Guillermo Grant Benavente, Concepción, Chile; entre enero-1995 y diciembre-2018. Se realizó un PSM con una relación 1:1 entre los pacientes operados con la técnica CC y SC. Posterior al PSM se balancearon las características basales. Resultados: Total 205 episodios de QHP en el período. Se realizó cirugía conservadora en 165 casos, 101 CC y 64 SC. Posterior al emparejamiento se obtuvieron 53 pacientes operados CC y 53 SC. No se observaron diferencias significativas en la presencia de fuga aérea persistente (CC = 9,4%; SC = 11,3%, p 0,75), empiema (CC = 3,8%; SC = 0%, p 0,49), días con pleurotomía (CC = 9,1 ± 8,9; SC 10,1 ± 10,7, p 0,39, mediana 6 versus 6 días, respectivamente), ni días de estadía posoperatoria (CC = 10,4 ± 9,0; SC = 11,7 ± 11,9, p 0,22, mediana 7 versus 7 días, respectivamente). Conclusiones: La cirugía SC demostró resultados comparables a la técnica CC en el tratamiento quirúrgico conservador del QHP.

Background: Thoracic Trauma (TT) is the cause of approximately a quarter of trauma deaths. The patients who undergo Thoracic Trauma Surgery (TTS) present a wide spectrum of characteristics and prognosis. Aim: To describe clinical characteristics, indications, temporality, morbidity, mortality and mortality associated variables in TTS patients. Materials and Method: Observational study of TT hospitalized patients, period January-1981 to December-2019. A review of operation notes and database was done. A logistic regression for mortality associated variables was made. To compare classification, type of TT and its temporal distribution, SPSS25® with chi-square test was used, considering significant p < 0.05. Results: A total of 808 (18.2%) of 4.448 TT patients required TTS, 767 (94.9%) were men with average age: 31.5 ± 13.8. The trauma was penetrating trauma due to a stab in most cases, 164 (20.3%) were polytraumatized. The surgery was urgent in 474 (58.7%), early in 41 (5.0%) and delayed in 293 (36.3%) cases. The global mortality was 6.7% and was significantly higher in the blunt TT, polytrauma, urgent and early surgery patients. Mortality in urgent TTS was 9.7%, early 4.9% and 2.0% in delayed (p < 0.001). Independent variables associated with mortality were observed. Conclusions: In our series, TTS were performed mainly in young men with penetrating TT. The group was heterogeneous regarding surgical indications, findings and intrathoracic or associated injuries. Multiple variables showed to influence significantly on mortality in patients who underwent TTS.

Resumen Introducción: El traumatismo torácico (TT) es la causa de aproximadamente un cuarto de las muertes por traumatismos. Los pacientes tratados con cirugía por traumatismo torácico (CTT) presentan un amplio espectro de características y pronósticos. Objetivos: Describir características clínicas, indicaciones, temporalidad, morbilidad, mortalidad y las variables asociadas a mortalidad en pacientes con CTT. Materiales y Método: Estudio observacional de pacientes tratados con CTT, período enero-1981 a diciembre-2019. Revisión de protocolos prospectivos de TT y base de datos. Se realizó regresión logística para variables asociadas a mortalidad. Se utilizó SPSS25® con prueba chi-cuadrado para comparar clasificación, tipo de TT y su distribución temporal, considerando significativo p < 0,05. Resultados: En total 808 casos (18,2%) de 4.448 TT requirieron CTT. Fueron hombres 767 (94,9%) y la edad promedio fue 31,5 ± 13,8 años. El traumatismo fue penetrante y por arma blanca en la mayoría de los casos. Fueron politraumatizados 164 (20,3%). La cirugía fue urgente en 474 (58,7%), precoz en 41 (5,0%) y diferida en 293 (36,3%) casos. La mortalidad global fue de 6,7% y fue significativamente mayor en TT contusos, politraumatizados y en cirugía urgente. La mortalidad fue 9,7% en CTT urgente, 4,9% en precoz y 2,0% en diferida (p < 0,001). Se observaron variables independientes asociadas a mortalidad. Conclusión: En nuestra serie, las CTT se realizaron principalmente en hombres jóvenes con TT penetrantes. Correspondieron a un grupo heterogéneo en cuanto a las indicaciones, hallazgos y lesiones intratorácicas y/o asociadas. Múltiples variables demostraron influir significativamente en la mortalidad de los pacientes tratados con CTT.

Background: Lung cancer is the world’s leading cause of cancer death. Aim: To describe the clinical, staging and survival characteristics of lung cancer in a public Chilean regional hospital. Material and Methods: Analysis of a prospective database of a thoracic surgery service, retrieving histologically confirmed lung cancer cases from January 2010 to December 2019 and reviewing their medical records. Cases were re-staged by the TNM-8 system and variables were compared between periods 2010-2014 and 2015-2019. Results: We retrieved 551 lung cancer cases, 333 (60 %) men, with a mean age of 65 years. Distant metastases were found in 72% of cases (excluding lymphatic metastases). Of the non-small cell lung cancers (NSCLC), 50 (10%) cases were in stage I, 18 (4%) in stage II, 81 (16%) in stage III and 347 (70%) in stage IV. Global five-year survival was 18%, 20% for NSCLC, 71% for excised NSCLC, 8% for non-excised NSCLC, 88% for stage I and 92% for subgroup IA. Resective surgery was performed in 81 (14%) cases. When comparing 2010-2014 and 2015-2019 periods, the frequency of resective surgery increased from 7% to 20%. Conclusions: The diagnosis of lung cancer was frequently made in advanced stages. There was a significant increase in early diagnosis and frequency of surgeries with curative intent in the second observation period.

Prosthetic valve replacement is the standard treatment for aortic valvulopathy. Due to the structural valve deterioration of biological prosthesis and the anticoagulation requirements of mechanical valves, the repair of aortic valve disease is receiving more attention in recent years. The Ozaki technique consists in the reconstruction of a trileaflet valve using autologous pericardium. We report our first two cases of successful reconstruction of the aortic valve using this technique with 12-month echocardiographic and 24-month clinical follow up.
