RESUMO

Diclofenac is an emerging pollutant: toxic, persistent, and bioaccumulative, present in several environmental niches in a concentration of parts per million. This pharmaceutical's biological removal was reported with various fungal species, showing promissory results. This work aimed at diclofenac removal by individually challenging the fungal species Pleurotus ostreatus, Aspergillus niger, and Penicillium roquefortii but triying to lower the biosorption nature of cell walls by NaCl addition. P. ostreatus removed 100% of the initial diclofenac concentration, whereas A. niger and P. roqueforti removed 74% and 32%, respectively. In all three cases, biosorption by polar interactions was negligible. We demonstrated that stressful environments, such as mineral media, force the fungus to take advantage of its metabolic tools to survive, hence showing higher removal capacity when limiting growth conditions. Bioremediation is an excellent alternative to give residual fungal biomass a secondary use.

RESUMO

Introducción: las infecciones generadas por microorganismos oportunistas (MO) o infecciones oportunistas (IO) son causa importante de morbimortalidad en pacientes oncológicos y se les atribuyen factores relacionados con los cuidados específicos de la atención en salud. Las alteraciones en el sistema inmunológico, la multirresistencia antimicrobiana, la neutropenia febril y la interrupción de la integridad cutánea son los factores más influyentes. Objetivo: describir las principales intervenciones y estrategias para reducir IO en pacientes oncológicos. Metodología: revisión integrativa de la literatura. Se incluyeron artículos en español, inglés y portugués indexados a los tesauros MeSH Y DeCS, en las bases de datos CINAHL, Nursing Ovid, Clinicalkey; el metabuscador de Google académico y la interfaz Pubmed. Resultados: se revisaron 56 estudios, fueron organizados en tres temáticas: factores de riesgo que influyen para adquirir una IO en pacientes oncológicos, infecciones por MO y cuidados de enfermería, los cuales se agruparon en subtemas como: educación, medidas estándar, de barrera, farmacológicas, nutrición, manejo de catéteres, cavidad bucal, piel y aspectos emocionales. Discusión: se evidencian factoresque influyen en la no adherencia por parte de los profesionales que están relacionados con sus posturas, el contexto social, el sistema sanitario y características de las GPC. Conclusión: fue posible describir las intervenciones y estrategias de prevención que permiten reducir de manera importante la morbimortalidad en pacientes oncológicos.


Introduction: infections caused by opportunistic microorganisms (OM) or opportunistic infections (OI) are an important source of morbidity and mortality in oncology patients and are attributed to factors related with specific procedures in health care. Alterations of the immune system, antimicrobial multidrug resistance, febrile neutropenia and impaired skin integrity are the most influential factors. Objective: to describe the main interventions and strategies to reduce OI in oncology patients. Methodology: integrative review of the literature. Articles in Spanish, English and Portuguese indexed in the MeSH and DeCS thesauri in the CINAHL, Nursing Ovid, Clinicalkey databases; the academic Google meta-search engine and the PubMed interface, were included. Results: 56 studies were reviewed and organized into three topics: risk factors associated with the development of OI in cancer patients, infections by OM and nursing care. These topics were grouped into subtopics such as: education, standard barrier and pharmacological measures, nutrition, IV catheter care, oral cavity, skin and emotional aspects. Discussion: factors influencing non-adherence of healthcare providers were found to be related with their attitude, social context, health system and characteristics of clinical practice guidelines. Conclusion: we describe the intervention and prevention strategies which allow a significant reduction in morbimortality in oncology patients.

RESUMO

Introducción: La atención en salud en tiempos de pandemia ha requerido un gran compromiso de los integrantes de los equipos de atención en salud, quienes se han visto afectados por los múltiples cambios. Objetivo: Describir la experiencia de cuidar durante la pandemia por Covid-19 de una auxiliar de enfermería en Bogotá. Metodología: Estudio cualitativo, relato biográfico, se realizó entrevista a una auxiliar de enfermería de primera línea en la atención, y análisis temático de la información. Resultados: El tema central permite aproximarse al proceso de transitar por el cambio, del cual se desarrollan cinco subtemas que visibilizan la vulnerabilidad de la participante ante esta situación y la urgente necesidad de atención. Conclusión: Cuidar en primera línea en tiempos de pandemia ha tenido múltiples implicaciones que trascienden el quehacer profesional y se reflejan en la vida personal, familiar y social. (AU)


Background: Health care in times of pandemic has required a great commitment of the members of health care teams, who have been affected by the many changes. Objective: To describe the experience of caring for a nursing assistant in Bogotá during the Covid-19 pandemic. Methods: Qualitative study, biographical account, an interview was conducted at a nursing assistant frontline care, and thematic analysis of information. Results: The central theme allows to approach the process of going through change, of which five sub-themes are developed that make visible the vulnerability of the participant in this situation and the urgent need for attention. Conclusions: Frontline care in times of pandemic has had many implications that go beyond the professional work and are reflected in the personal, family and social life. (AU)
