Defining typologies of universities through a DEA-MDS analysis: An institutional characterization for formative evaluation purposes

Universities are organizational structures with individual activity mixes or strategies that lead to different performance levels by mission. Evaluation techniques based on performance indicators or rankings risk rewarding just a specific type of university and undermining university diversification: They usually introduce homogenizing pressures and risk displacing university objectives- neglecting their socio-economic contribution and focusing on succeeding on the evaluation system. In this study, we propose an alternative evaluation method that overcomes these limitations. We produce a multidimensional descriptive classification of universities into typologies, while analysing the relation between their institutional factors (characteristics) and their (technical) efficiency performance from a descriptive perspective. To do so we apply bootstrap data envelopment analysis (DEA) and multidimensional scaling analysis (MDS), performing a so-called DEAMDS analysis on data on the Spanish university system, and unlike previous studies, we include data on an important dimension of the third mission of universities (specifically knowledge transfer, KT) in their characterization. We identify six types of (homogeneous) universities. Results indicate that to be fairly efficient, universities may focus on teaching, KT, or overall efficiency but always have to fairly perform in research. Additionally, results confirm the relevance of the third mission as a source of institutional diversity in higher education. This approach could be used to address an alternative evaluation methodology for higher education institutions with formative purposes, evaluating universities according to their unique characteristics for the improvement of HE system

Formación de callos e inducción de brotes a partir de tejido intercalar de ramas de plantas adultas de Guadua angustifolia Kunth

Bamboo plants are largely used in building programs, furniture construction among others. Guadua angustifolia Kunth is a bamboo original from Ecuador and Colombia with certain interesting characteristics for reforestation programs. Vegetative propagation of these species is limited taking into account the desire to introduce them for production. Obtaining callus formation from the intercalar tissues of Guadua braches was the objective of this project. Starting material was disinfected using mercury bichlorine (0.2%) for a period of 10 minutes. Intercalar tissue segments were established in culture medium supplemented with picloram. Callus formation was obtained from these explants and the presence of green shoots was achieved with 6-BAP (benzylaminopurine).Key words: bamboo, temporal immersion, picloramLos bambúes tienen importancia para los programas de construcción y de fabricación de muebles, entre otras aplicaciones. Guadua angustifolia Kunth es un bambú originario de Ecuador y Colombia con ciertas características particulares, lo cual es de interés para los programas de reforestación.

Management of acute diverticulitis with pericolic free gas (ADIFAS). an international multicenter observational study

Background: There are no specific recommendations regarding the optimal management of this group of patients. The World Society of Emergency Surgery suggested a nonoperative strategy with antibiotic therapy, but this was a weak recommendation. This study aims to identify the optimal management of patients with acute diverticulitis (AD) presenting with pericolic free air with or without pericolic fluid. Methods: A multicenter, prospective, international study of patients diagnosed with AD and pericolic-free air with or without pericolic free fluid at a computed tomography (CT) scan between May 2020 and June 2021 was included. Patients were excluded if they had intra-abdominal distant free air, an abscess, generalized peritonitis, or less than a 1-year follow-up. The primary outcome was the rate of failure of nonoperative management within the index admission. Secondary outcomes included the rate of failure of nonoperative management within the first year and risk factors for failure. Results: A total of 810 patients were recruited across 69 European and South American centers; 744 patients (92%) were treated nonoperatively, and 66 (8%) underwent immediate surgery. Baseline characteristics were similar between groups. Hinchey II-IV on diagnostic imaging was the only independent risk factor for surgical intervention during index admission (odds ratios: 12.5, 95% CI: 2.4-64, P =0.003). Among patients treated nonoperatively, at index admission, 697 (94%) patients were discharged without any complications, 35 (4.7%) required emergency surgery, and 12 (1.6%) percutaneous drainage. Free pericolic fluid on CT scan was associated with a higher risk of failure of nonoperative management (odds ratios: 4.9, 95% CI: 1.2-19.9, P =0.023), with 88% of success compared to 96% without free fluid ( P <0.001). The rate of treatment failure with nonoperative management during the first year of follow-up was 16.5%. Conclusion: Patients with AD presenting with pericolic free gas can be successfully managed nonoperatively in the vast majority of cases. Patients with both free pericolic gas and free pericolic fluid on a CT scan are at a higher risk of failing nonoperative management and require closer observation

Propagación in vitro de bambú chino (Dracaena Sanderiana l.)

Con el objetivo de establecer un protocolo para la propagación in vitro de Bambú chino (Dracaena sanderiana L.), se evaluaron diferentes tiempos de desinfección de las yemas con bicloruro de mercurio (HgCl2) a 0.2% (m/v), distintas condiciones de cultivo para el establecimiento de las yemas, tanto en condiciones de luz y oscuridad, así como diferentes formas de cultivo y manejo de los explantes para la proliferación de los brotes y distintos niveles de AIB para el enraizamiento de los brotes. Se logró realizar el establecimiento in vitro de la Dracaena sanderiana a partir de yemas laterales de estacas de plantas adultas, en medio de cultivo MS (1962) con 1 mg L-1 de BAP en estado semisólido y bajo condiciones de oscuridad. Para la proliferación de brotes, el seccionamiento longitudinal de estos y los sistemas de inmersión permanente, en el medio de cultivo MS (1962) enriquecido con BAP (2 mg L-1) combinado con ANA resulto ser el mejor tratamiento. La aclimatización de los brotes de Dracaena sanderiana se realizó en un sustrato compuesto de zeolita cachaza (1:1) en condiciones de casa de cultivo, con un sistema de riego por microjet

Safety and Outcome of Revascularization Treatment in Patients With Acute Ischemic Stroke and COVID-19: The Global COVID-19 Stroke Registry.

BACKGROUND AND OBJECTIVES COVID-19 related inflammation, endothelial dysfunction and coagulopathy may increase the bleeding risk and lower efficacy of revascularization treatments in patients with acute ischemic stroke. We aimed to evaluate the safety and outcomes of revascularization treatments in patients with acute ischemic stroke and COVID-19. METHODS Retrospective multicenter cohort study of consecutive patients with acute ischemic stroke receiving intravenous thrombolysis (IVT) and/or endovascular treatment (EVT) between March 2020 and June 2021, tested for SARS-CoV-2 infection. With a doubly-robust model combining propensity score weighting and multivariate regression, we studied the association of COVID-19 with intracranial bleeding complications and clinical outcomes. Subgroup analyses were performed according to treatment groups (IVT-only and EVT). RESULTS Of a total of 15128 included patients from 105 centers, 853 (5.6%) were diagnosed with COVID-19. 5848 (38.7%) patients received IVT-only, and 9280 (61.3%) EVT (with or without IVT). Patients with COVID-19 had a higher rate of symptomatic intracerebral hemorrhage (SICH) (adjusted odds ratio [OR] 1.53; 95% CI 1.16-2.01), symptomatic subarachnoid hemorrhage (SSAH) (OR 1.80; 95% CI 1.20-2.69), SICH and/or SSAH combined (OR 1.56; 95% CI 1.23-1.99), 24-hour (OR 2.47; 95% CI 1.58-3.86) and 3-month mortality (OR 1.88; 95% CI 1.52-2.33).COVID-19 patients also had an unfavorable shift in the distribution of the modified Rankin score at 3 months (OR 1.42; 95% CI 1.26-1.60). DISCUSSION Patients with acute ischemic stroke and COVID-19 showed higher rates of intracranial bleeding complications and worse clinical outcomes after revascularization treatments than contemporaneous non-COVID-19 treated patients. Current available data does not allow direct conclusions to be drawn on the effectiveness of revascularization treatments in COVID-19 patients, or to establish different treatment recommendations in this subgroup of patients with ischemic stroke. Our findings can be taken into consideration for treatment decisions, patient monitoring and establishing prognosis
