Objective: to carry out an integrative review of the literature on autobiographical narratives as a discursive activity in the older adult with neurocognitive disorder. Methods: a descriptive study that covered the Scopus, SciELO, PubMed, and Science Direct databases, from 2009 to 2019, using the keywords autobiographical, narrative, dementia, reminiscence, the elderly, and the Boolean operator. A narrative synthesis was adopted considering the characteristics of the clinical, and methodological heterogeneity of the studies. Results: the results included 3 articles published between 2012 and 2018, in the English language, from the United Kingdom, Brazil, and Argentina, which highlighted the autobiographical narratives. Although in a strict sense they did not present the narrative as a specific objective of the autobiographical study, they did provide interesting and related data which justified their inclusion. Conclusion: it is observed that the literature researched presents a limited number of articles, adressing the autobiographical narrative as a discursive activity in the elderly with neurocognitive disorder.

Carbon dioxide-based polyoxazolidinones (POxa) are an emerging subclass of non-isocyanate polyurethanes for high temperature applications. Current POxa with rigid linkers suffer from limited solubility that hinders synthesis and characterization. Herein, we report the addition of alkyl and alkoxy solubilizing groups to rigid spirocyclic POxa and their poly(hydroxyoxazolidinone) (PHO) precursors. The modified polymers were soluble in up to 6 organic solvents, enabling characterization of key properties (i.e., molar mass and polymer structure) using solution-state methods. Dehydration of PHO to POxa changed solubility from highly polar to less polar solvents and improved thermal stability by 76–102 °C. The POxa had relatively high glass transition (85–119 °C) and melting (190–238 °C) temperatures tuned by solubilizing group structure. The improved understanding of factors affecting solubility, structure-property relationships, and degradation pathways gained in this study broadens the scope of soluble POxa and enables more rational design of this promising class of materials.

Wastewater with Contaminants of Emerging Concern (CEC) can be generated from different sources as industry, agriculture and urban and hospital wastes. Heterogeneous Photocatalysis (HP) with TiO2 is one of the Advanced Oxidation Processes (AOPs) most suitable for water treatment with CEC. In this research, three CEC: Safranin T (SF), 2,4-dichlorophenoxyacetic acid (2,4-D) and Sulfacetamide (SAM) degradation was evaluated by solar-HP in a quartz wall reactor. First, 365 nm wavelength radiation was used and the best operating conditions was determined under the high flow and aeration configuration, obtaining a removal rate of 48.05% for SF, 11.64% for 2,4-D and 6.98 for SAM. Then, under these conditions, SF, SAM and 2,4-D degradation with solar lighting was made on 4 radiation collector systems configurations, Flat Plate Collector (FPC), V Collector (VC), Parabolic Collector (PC) and Compound Parabolic Cylinder Collector (CPC) until reaching the same value of accumulated energy (122.77 kJ m− 2) finding that the PC had the best performance in the treatment for the three pollutants. Finally, the Collector Impact Ratio Factor (CIRF) for the pollutants was calculated, achieving until 12 times degradation for SAM.

Introducción: el síndrome de West es una encefalopatía epiléptica grave que se presenta generalmente en el primer año de vida. Este síndrome se caracteriza por la tríada electroclínica de espasmos en salvas, patrón electroencefalográfico de hipsarritmia y retraso psicomotor, aunque este último no es indispensable para su diagnóstico. Se conoce poco sobre su fisiopatología y manifestación clínica, por lo que sería pertinente difundirlos a la comunidad para atender estos casos de manera oportuna. Caso clínico: se presenta el caso de un lactante de 7 meses de edad, producto de embarazo gemelar monocorial biamniótico y antecedentes de síndrome de transfusión feto fetal. El paciente consulta por manifestaciones clínicas consistentes en movimientos espasmódicos de miembros superiores, salvas conformadas en promedio de 10 espasmos de aproximadamente 2 segundos de duración, la madre refiere que el niño convulsiona desde los 4 meses. Luego de ser valorado por el servicio de neurología pediátrica y de acuerdo a los resultados de imagenología se concluye que el paciente presenta tríada sintomática clásica del síndrome de West. El niño es tratado con ácido valproico y vigabatrina, presentando una mejoría clínica que se evidenció en disminución del número de crisis de manera significativa.  Conclusión: el síndrome de West debe ser objeto de conocimiento por parte de los médicos para realizar un diagnóstico temprano y definir el tratamiento adecuado y oportuno.
