Experiencias relacionadas con la evolución del método didáctico: incorporación del uso de la plataforma moodle, videos educativos y cd interactivos

Globalization and the explosion of the Information and Communication Technologies (ICT) have yet to be integrated into existing models of management and education. The performance of the teaching activity needs to approach reflectively the pedagogic model under which the education of a discipline will be arranged. In this work a teaching experience is exposed in the University of Malaga

Analysis of University STEM Students’ Mathematical, Linguistic, Rhetorical–Organizational Assignment Errors

Although Error Analysis (EA) has been broadly used in Foreign Language and Mother Tongue learning contexts, it has not been applied in the field of engineering and by STEM (Science, Technology, Engineering, and Mathematics) students in a systematic way. In this interdisciplinary pilot study, we applied the EA methodology to a wide corpus of exercises and essays written by third-year students of mechanical engineering, with the main purpose of achieving a precise diagnosis of the students’ strengths and weaknesses in writing skills. For the analysis to be as exhaustive as possible, the errors were typologized into three main categories (linguistic, mathematical, and rhetorical–organizational), each of which is, in turn, subdivided into 15 items. The results show that the predominant errors are rhetorical–organizational (39%) and linguistic (38%). The application of EA permits the precise identification of the areas of improvement and the subsequent implementation of an educational design that allows STEM students to improve their communicative strategies, especially those related to the writing skills and, more precisely, those having to do with the optimal use of syntax, punctuation, rhetorical structure of the text, and mathematical coherence

A Rubric to Assess and Improve Technical Writing in Undergraduate Engineering Courses

Although there is consensus in the literature that writing skills are important in STEM (Science, Technology, Engineering, and Mathematics) studies, they are often neglected. However, some efforts have been made to correct this deficiency, one of them being the development of assessment rubrics. This study seeks to contribute to the discussion by presenting the results of the application of a rubric designed to assess the writing skills of a group of 3rd year engineering students. This rubric, which includes linguistic and rhetorical-organizational criteria alongside the mathematical and technical, was used to assess a number of written exercises and essays submitted by students in a 15-week course. The main interest of this study was to test the efficacy of the rubric as a diagnostic tool, conceived to detect the areas of improvement in the students’ written performance and, ultimately, to also help them to achieve higher levels of competence. This goal was achieved, as one of the main conclusions of the study is that, although students usually master the technical aspects of the course, they must improve the linguistic and rhetorical aspects of their written communication. It can likewise be said that all the participants involved in the study profited in one way or another from the application of the rubric and contributed to identifying the ways in which the rubric itself can be improved for future application

The unfavorable lipid environment reduced caveolin-1 expression in apical membranes from human preeclamptic placentas

Syncytialization process is associated with a reduction in the number of caveolas, and a decreased of caveolin-1 (Cav-1). Differentiation of syncytiotrophoblast affects the membranes phospholipid composition. Thus, disturbances in these processes are related to pathological conditions such as preeclampsia. Objective To analyse the lipid composition of the apical (MVM) and the basal (BM) membranes of syncytiotrophoblast and its relationship with Cav-1 expression in normal and preeclamptic placentas. Molecular expression of Cav-1 was determined in MVM and BM from normal and preeclamptic placentas and in detergent-resistant membranes (DRMs). Phospholipids were analyzed by thin layer chromatography. Cholesterol was also determined by enzymatic assay. Membrane fluidity was evaluated by electron paramagnetic resonance. Sphingomyelin (SM) molecular species were analyzed and quantified by gas-liquid chromatography and mass spectrometry. Cav-1 was significantly reduced in MVM from preeclamptic placentas. Regarding Cav-1 localization, it was barely detectable in syncytiotrophoblast but it was present in the endothelium. Western blots also showed a significantly decrease of Cav-1 in the apical DRMs from preeclamptic placentas. Lipid analysis showed an increase SM in MVM from preeclamptic placentas without changes in cholesterol. Preeclamptic MVM fluidity decreased significantly and we found an increase in C18:1 fatty acids of SM. We concluded that preeclamptic-MVMs are more rigid than normal ones, possible due to an increment on SM. Moreover, the increase of long and unsaturated SM molecular specie found in these vesicles may disrupt the ability of SM to assemble into lipid rafts in the luminal leaflet of the bilayer, creating an unfavorable environment for Cav-1.Instituto de Investigaciones Bioquímicas de La Plat

Late HIV Diagnosis but Earlier Antiretroviral Treatment Initiation in Northwest Spain: Impact of Current Treatment Guidelines.

BACKGROUND: Current HIV treatment guidelines recommend antiretroviral treatment (ART) initiation for all HIV-infected individuals regardless of CD4 count. This study evaluates the immunological and virological status and the clinical characteristics of patients who have started ART in the last 8 years in the Northwest of Spain. METHODS: All HIV-infected patients who have started ART between January 2009 and December 2016 at a reference hospital in the Northwest of Spain were included in this retrospective observational study. Epidemiological, clinical, and immunovirological features and antiretroviral drugs used for initiation were recorded. A statistical analysis was performed using SPSS version 19 software. Categorical and continuous variables were compared by the specific statistical tests, and a logistic regression model was used to identify time associated with Center for Disease Control and Prevention (CDC) categories change. RESULTS: A high proportion of HIV-infected patients (66.7%) had initiated ART with CD4 counts <350 cells/mm(3) in the last 8 years. From these, most of them (68.3%) had <350 CD4 counts at first contact with HIV specialist medical team, 12.2% had no indications for ART initiation in the last clinic visit before ART initiation according to the national guidelines at that moment, 11.0% were lost to follow-up because of lack of compliance with scheduled visits and 8.5% of patients refused treatment. A logistic regression model showed that a delay of one month since the first contact with HIV specialist medical team to ART initiation involves a risk of worsening in the CDC clinical category (odds ratio: 1.02 [95% confidence interval: 1.012-1.029]; P < .001). A trend towards an earlier start of ART was observed during 2015 and 2016, likely influenced by the last treatment guidelines recommendations. CONCLUSION: High proportion of HIV-infected patients (66.7%) had initiated ART with CD4 counts <350 cells/mm(3) in the last 8 years. The main reasons for this problem were analyzed and an important rate of late diagnosis was identified. However, a trend towards an earlier start of ART was observed during 2015 and 2016, likely influenced by the last treatment guidelines recommendations. These findings highlight the need to promote and facilitate HIV testing to reduce the late diagnosis as well as counseling on HIV prevention, treatment, and linkage care

Golimumab as rescue therapy for refractory immune-mediated uveitis: a three-center experience

OBJECTIVE: To evaluate, in three Spanish tertiary referral centres, the short-term safety and efficacy of golimumab (GLM) for treatment of immune-mediated uveitis resistant to previous immunosuppressive therapy. METHODS: Nonrandomized retrospective interventional case series. Thirteen patients with different types of uveitis that were resistant to treatment with at least 2 previous immunosuppressors were included in this study. All included patients were treated with GLM (50 mg every four weeks) during at least 6 months. Clinical evaluation and treatment-related side effects were assessed at least four times in all included patients. RESULTS: Eight men and 5 women (22 affected eyes) with a median age of 30 years (range 20-38) and active immune-mediated uveitides were studied. GLM was used in combination with conventional immunosuppressors in 7 patients (53.8%). GLM therapy achieved complete control of inflammation in 12/13 patients (92.3%) after six months of treatment. There was a statistically significant improvement in mean BCVA (0.60 versus 0.68, P = 0.009) and mean 1 mm central retinal thickness (317 versus 261.2 µ, P = 0.05) at the six-month endpoint when compared to basal values. No major systemic adverse effects associated with GLM therapy were observed. CONCLUSIONS: GLM is a new and promising therapeutic option for patients with severe and refractory uveitis

Discontinuation due to neuropsychiatric adverse events with efavirenz- and dolutegravir-based antiretroviral therapy: a comparative real-life study

Obervational study[Abstract] Objectives: Despite the high efficacy of antiretroviral treatment, no drug is free from adverse events (AEs). Efavirenz (EFV) and dolutegravir (DTG) are antiretroviral drugs for which neuropsychiatric adverse events (NPAEs) have been described. This study evaluated the safety and tolerability of DTG-based and EFV-based antiretroviral regimens in HIV-infected patients. Methods: A retrospective observational study was carried out in HIV-infected patients who started DTG- or EFV-based antiretroviral treatment from January 2008 to December 2018 at a reference hospital in north-western Spain. Epidemiological, clinical and immunovirological data were recorded. A statistical analysis was performed with SPSS software. Results: A total of 282 DTG- and 148 EFV-based therapies were initiated. During follow-up, statistically significant differences have been found between the rate of patients who discontinued DTG and EFV due to AEs (12.1% vs 35.8%, p&lt;0.001) and the main AEs in both groups, NPAEs (8.2% vs 25.0%, p&lt;0.001). Female gender (OR 2.610 (95% CI 1.327 to 5.133), p=0.005) was associated with discontinuations due to AEs. Patients with documented psychiatric disorders were at higher risk of discontinuation due to NPAEs (OR 4.782 (95% CI 1.190 to 19.220), p=0.027). The multivariate analysis showed a 61.2% risk reduction in benzodiazepine prescriptions in patients treated with DTG. In both groups, patients needed consultation and follow-up in the psychiatry unit (16.9% in the EFV group and 8.9% in the DTG group, p=0.021). Conclusions: We found a high rate of discontinuations due to AEs and NPAEs, prescription of benzodiazepines and a requirement for consultation in a psychiatric unit in both treatment groups, especially with EFV

Renal profile of patients treated with elvitegravir/ cobicistat/emtricitabine/tenofovir alafenamide fumarate and dolutegravir/abacavir/lamivudine: 120-week results from a real-world cohort

[Abstract] Elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide fumarate (EVG/c/FTC/TAF) and dolutegravir/abacavir/lamivudine (DTG/ABC/3TC) are currently available for HIV patients. Objectives: This study evaluated modifications in the renal safety profile in a large real-world cohort of patients who had received EVG/c/FTC/TAF or DTG/ABC/3TC. Methods: A retrospective observational study of HIV-infected patients who received EVG/c/FTC/TAF or DTG/ABC/3TC between March 2015 and June 2019 at a reference hospital in north-western Spain was conducted. Epidemiological, clinical, immunovirological data and information regarding antiretroviral therapy were recorded. The statistical differences between treatments were calculated. Results: A total of 457 patients were evaluated, 266 using EVG/c/FTC/TAF and 191 using DTG/ABC/3TC. Up to week 120, serum creatinine improved in both study groups among experienced patients (EVG/c/FTC/TAF 1.01±0.24 vs 0.91±0.19, p<0.001; DTG/ABC/3TC 1.08±0.24 vs 1.02±0.31, p<0.001), while in naïve patients serum creatinine remained stable compared with baseline. Statistically significant differences were found in serum creatinine when comparing both treatments at week 48 in experienced (0.94±0.21 vs 1.09±0.28, p<0.001) and naïve patients (0.89±0.16 vs 1.06±0.20, p=0.001), and among experienced patients at week 120 (0.91±0.19 vs 1.02±0.31, p=0.015) for the EVG/c/FTC/TAF and DTG/ABC/3TC groups, respectively. During the follow-up, 39 patients in EVG/c/FTC/TAF and 33 in DTG/ABC/3TC (p=0.449) discontinued treatment. The main reason for stopping treatment was adverse events, which were similar in both groups. Conclusions: During the follow-up, patients experienced changes that were not clinically relevant in both treatment groups. Differences in renal events were not found
