    Access to healthy or diseased human neural tissue is a daunting task and represents a barrierfor advancing our understanding about the cellular, genetic, and molecular mechanisms underly-ing neurogenesis and neurodegeneration. Reprogramming of somatic cells to pluripotency bytransient expression of transcription factors was achieved a few years ago. Induced pluripotentstem cells (iPSC) from both healthy individuals and patients suffering from debilitating, life-threatening neurological diseases have been differentiated into several specific neuronal sub-types. An alternative emerging approach is the direct conversion of somatic cells (i.e., fibro-blasts, blood cells, or glial cells) into neuron-like cells. However, to what extent neuronal directconversion of diseased somatic cells can be achieved remains an open question. Optimizationof current expansion and differentiation approaches is highly demanded to increase the differ-entiation efficiency of specific phenotypes of functional neurons from iPSCs or through somaticcell direct conversion. The realization of the full potential of iPSCs relies on the ability to pre-cisely modify specific genome sequences. Genome editing technologies including zinc fingernucleases, transcription activator-like effector nucleases, and clustered regularly interspacedshort palindromic repeat/CAS9 RNA-guided nucleases have progressed very fast over the lastyears. The combination of genome-editing strategies and patient-specific iPSC biology will offera unique platform for in vitro generation of diseased and corrected neural derivatives for per-sonalized therapies, disease modeling and drug screening

    This paper analyzes the relationship between geographic research and teaching proposals in this discipline, developed within the Semillero de Didáctica de la Geografía y las Ciencias Sociales attached to the Universidad del Tolima, Colombia, based on research work carried out as a degree option. This proposal is advanced from two epistemological approaches: from radical geography, to generate socio-spatial readings in the school from a curricular proposal, and from a humanistic approach, to highlight the construction of territorial identities by virtue of the historical memory in rural scenarios. The text focuses on the exposition of urban analysis from the spatial transformations and on the study of territorial identity from historical memory, as well as on the importance of the field trip for the didactic training in the seedbed.  El presente documento analiza la relación existente entre la investigación geográfica y las propuestas de enseñanza en esta disciplina, desarrolladas al interior del Semillero de Didáctica de la Geografía y las Ciencias Sociales adscrito a la Universidad del Tolima, Colombia, a partir de trabajos de investigación realizados como opción de grado.

    BACKGROUND Concern has risen about the effects of COVID-19 in interstitial lung disease (ILD) patients. The aim of our study was to determine clinical characteristics and prognostic factors of ILD patients admitted for COVID-19. METHODS Ancillary analysis of an international, multicenter COVID-19 registry (HOPE: Health Outcome Predictive Evaluation) was performed. The subgroup of ILD patients was selected and compared with the rest of the cohort. RESULTS A total of 114 patients with ILDs were evaluated. Mean ± SD age was 72.4 ± 13.6 years, and 65.8% were men. ILD patients were older, had more comorbidities, received more home oxygen therapy and more frequently had respiratory failure upon admission than non-ILD patients (all p < 0.05). In laboratory findings, ILD patients more frequently had elevated LDH, C-reactive protein, and D-dimer levels (all p < 0.05). A multivariate analysis showed that chronic kidney disease and respiratory insufficiency on admission were predictors of ventilatory support, and that older age, kidney disease and elevated LDH were predictors of death. CONCLUSIONS Our data show that ILD patients admitted for COVID-19 are older, have more comorbidities, more frequently require ventilatory support and have higher mortality than those without ILDs. Older age, kidney disease and LDH were independent predictors of mortality in this population.S

    Background. Most evidence regarding anticoagulation and COVID-19 refers to the hospitalization setting, but the role of oral anticoagulation (OAC) before hospital admission has not been well explored. We compared clinical outcomes and short-term prognosis between patients with and without prior OAC therapy who were hospitalized for COVID-19. Methods. Analysis of the whole cohort of the HOPE COVID-19 Registry which included patients discharged (deceased or alive) after hospital admission for COVID-19 in 9 countries. All-cause mortality was the primary endpoint. Study outcomes were compared after adjusting variables using propensity score matching (PSM) analyses. Results. 7698 patients were suitable for the present analysis (675 (8.8%) on OAC at admission: 427 (5.6%) on VKAs and 248 (3.2%) on DOACs). After PSM, 1276 patients were analyzed (638 with OAC; 638 without OAC), without significant differences regarding the risk of thromboembolic events (OR 1.11, 95% CI 0.59-2.08). The risk of clinically relevant bleeding (OR 3.04, 95% CI 1.92-4.83), as well as the risk of mortality (HR 1.22, 95% CI 1.01-1.47; log-rank p value = 0.041), was significantly increased in previous OAC users. Amongst patients on prior OAC only, there were no differences in the risk of clinically relevant bleeding, thromboembolic events, or mortality when comparing previous VKA or DOAC users, after PSM. Conclusion. Hospitalized COVID-19 patients on prior OAC therapy had a higher risk of mortality and worse clinical outcomes compared to patients without prior OAC therapy, even after adjusting for comorbidities using a PSM. There were no differences in clinical outcomes in patients previously taking VKAs or DOACs. This trial is registered with NCT04334291/EUPAS34399

    Background: The presence of any underlying heart condition could influence outcomes during the coronavirus disease 2019 (COVID-19). Methods: The registry HOPE-COVID-19 (Health Outcome Predictive Evaluation for COVID-19, NCT04334291) is an international ambispective study, enrolling COVID-19 patients discharged from hospital, dead or alive. Results: HOPE enrolled 2798 patients from 35 centers in 7 countries. Median age was 67 years (IQR: 53.0–78.0), and most were male (59.5%). A relevant heart disease was present in 682 (24%) cases. These were older, more frequently male, with higher overall burden of cardiovascular risk factors (hypertension, dyslipidemia, diabetes mellitus, smoking habit, obesity) and other comorbidities such renal failure, lung, cerebrovascular disease and oncologic antecedents (p &lt; 0.01, for all). The heart cohort received more corticoids (28.9% vs. 20.4%, p &lt; 0.001), antibiotics, but less hydroxychloroquine, antivirals or tocilizumab. Considering the epidemiologic profile, a previous heart condition was independently related with shortterm mortality in the Cox multivariate analysis (1.62; 95% CI 1.29–2.03; p &lt; 0.001). Moreover, heart patients needed more respiratory, circulatory support, and presented more in-hospital events, such heart failure, renal failure, respiratory insufficiency, sepsis, systemic infammatory response syndrome and clinically relevant bleedings (all, p &lt; 0.001), and mortality (39.7% vs. 15.5%; p &lt; 0.001).Conclusions: An underlying heart disease is an adverse prognostic factor for patients suffering COVID-19. Its presence could be related with different clinical drug management and would benefit from maintaining treatment with angiotensin converting enzyme inhibitors or angiotensin receptor blockers during in-hospital stay
