Ten steps to transform ideas into product innovations: An interdisciplinary collaboration between nursing and engineering.

AIMS: To describe the development process of a device from the conception of the idea to the first contact with the commercial environment, and to demonstrate its practical application through an interdisciplinary collaboration between nursing and engineering for the design of a protective device for peripheral venous catheters. BACKGROUND: Nurses are key agents for identifying unresolved needs or problems related to nursing care. To address these needs, creative ideation processes are often triggered among nurses to seek technological answers to these challenges. RESULTS: The ten steps to develop a device are presented: (1) detecting an unsatisfied clinical need; (2) searching for preexisting marketed products; (3) searching for patents; (4) maintaining confidentiality throughout the process; (5) obtaining institutional support; (6) forming a multidisciplinary team; (7) developing the idea; (8) applying for a patent; (9) building the prototype; (10) marketing the device. This methodology was applied to design a protective device for peripheral venous catheters in hospitalized patients. CONCLUSIONS: Nurses can play a key role in the promotion of healthcare innovation in their field to improve procedures, thanks to their direct contact with patients, and by providing their insight on devices that can enhance patient care. The successful interdisciplinary collaboration between nurses and engineers can provide a response to relevant clinical problems such as the manipulation or removal of peripheral venous catheters. IMPLICATIONS FOR NURSING AND/OR HEALTH POLICY: A hospital policy is required to encourage the participation of nurses in innovative actions. Furthermore, it is important to support nurse leaders who can play a pivotal role in incorporating creativity into work environments and empowering other nurses to innovatively address clinical issues. NO PATIENT OR PUBLIC CONTRIBUTION: This article describes the process for developing a health device.

Quality of Life after Radical Prostatectomy: A Longitudinal Study.

BACKGROUND: Men with prostate cancer who undergo radical prostatectomy experience a decrease in quality of life, often related to sexual disfunction and urinary incontinence. Knowing and measuring the impact of radical prostatectomy on the individual's social, emotional, and family quality of life could help to plan and develop an appropriate, patient-centred therapeutic approach. AIM: In this study, we aimed to evaluate changes in quality of life of patients with prostate cancer before and after radical prostatectomy. METHODS: A longitudinal, observational study of 114 participants was conducted using the method of test-retest. Quality of life before and after radical prostatectomy was measured through the following self-administered questionnaires: (1) The EORTC QLQ-C30 in its Spanish version was used to assess the generic quality of life the participants; (2) the EORTC QLQ-PR25 in its Spanish version was used to assess the specific, health-related quality of life of prostate cancer patients. RESULTS: A total of 114 men took part in this study. The results from the QLQ-C30 questionnaire indicated an improvement in the dimensions of emotional role and cognitive function, as well as in the symptoms of fatigue, pain, nausea and vomiting, insomnia, and loss of appetite, after surgery. Patients scored lower in the dimensions of role functioning, social function, and economic impact after radical prostatectomy. According to the results from the QLQ-PR25 questionnaire, 61.40% of the participants experienced sexual impotence and 26.31% suffered urinary incontinence after surgery. There were significant differences in some postsurgical outcomes between patients who had neurovascular bundles preserved and those who had not. CONCLUSIONS: In-depth knowledge of, and measurement of changes in, quality of life after radical prostatectomy should allow for comprehensive, multidisciplinary, patient-centred care planning. Psychosocial assessment, both before and after surgery, is crucial in patients with prostate cancer. This study was prospectively registered with the CEIC-A on 2012-06-27, with registration number C.P.-C.I. PI12/0088.

Impact of natural degradation of the invasive alga Rugulopteryx okamurae on anaerobic digestion: Heavy metal pollution and kinetic performance.

This study shows, for the first time, how the natural biodegradation of the Phaeophyceae Rugulopteryx okamurae (R.o.) affects its methane yield, by biochemical methane potential assays, and the methane production kinetics. Additionally, a mechanical (zeolite-assisted milling) and a thermal (120 °C, 45 min) pretreatments were assessed. The highest methane yield was obtained from the mechanically pretreated fresh ashore biomass (219 (15) NLCH4 kgVS-1), which presents the use of zeolite during milling as an economical alternative for heavy metal toxicity reduction. Moreover, no significant differences were observed between the other tests (with the exception of the lowest value obtained for the mechanically pretreated fresh R.o.). Low methane yields were linked to the heavy metal content. However, an increase of 28.5 % and 20.0 % in the k value was found for the untreated fresh R.o. biomass and fresh ashore biomass, respectively, when subjected to thermal pretreatment. Finally, an enhancement of 80.5 % in the maximum methane production rate was obtained for the fresh ashore biomass milled with zeolite compared to the untreated fresh ashore biomass.

Liquid Biopsy Detects Early Molecular Response and Predicts Benefit to First-Line Chemotherapy plus Cetuximab in Metastatic Colorectal Cancer: PLATFORM-B Study.

PURPOSE: Chemotherapy plus anti-EGFR is standard first-line therapy in RAS wild-type (wt) metastatic colorectal cancer (mCRC), but biomarkers of early response are clinically needed. We aimed to define the utility of ctDNA to assess early response in patients with mCRC receiving first-line anti-EGFR therapy. EXPERIMENTAL DESIGN: Prospective multicentric study of tissue patients with RAS wt mCRC treated with first-line chemotherapy plus cetuximab undergoing sequential liquid biopsies. Baseline and early (C3) ctDNA were analyzed by NGS. Trunk mutations were assessed as surrogate marker of total tumor burden. RAS/BRAF/MEK/EGFR-ECD were considered mutations of resistance. ctDNA results were correlated with clinical outcome. RESULTS: One hundred patients were included. ctDNA was detected in 72% of patients at baseline and 34% at C3. Decrease in ctDNA trunk mutations correlated with progression-free survival (PFS; HR, 0.23; P = 0.001). RAS/BRAF were the only resistant mutations detected at C3. An increase in the relative fraction of RAS/BRAF at C3 was followed by an expansion of the RAS clone until PD, and was associated with shorter PFS (HR, 10.5; P < 0.001). The best predictor of response was the combined analysis of trunk and resistant mutations at C3. Accordingly, patients with "early molecular response" (decrease in trunk and decrease in resistant mutations) had better response (77.5% vs. 25%, P = 0.008) and longer PFS (HR, 0.18; P < 0.001) compared with patients with "early molecular progression" (increase in trunk and/or increase in resistant mutations). CONCLUSIONS: ctDNA detects early molecular response and predicts benefit to chemotherapy plus cetuximab. A comprehensive NGS-based approach is recommended to integrate information on total disease burden and resistant mutations. See related commentary by Eluri et al., p. 302.

Turning an invasive alien species into a valuable biomass: Anaerobic digestion of Rugulopteryx okamurae after thermal and new developed low-cost mechanical pretreatments.

The invasive alien seaweed Rugulopteryx okamurae (R.o.) has spread quickly through the Mediterranean Sea causing an unprecedented ecological impact. A solution integrated into a circular economy model is needed in order to curb the negative effects of its presence. Anaerobic digestion (AD) is proposed as a feasible process able to transform biomass into renewable energy. Nevertheless, in order to improve the methane yield and surpass the drawbacks associated with AD processes, this research proposes a thermal pretreatment and a new developed method where the macroalgae is mechanically pretreated with zeolite. Chemical and microstructure characterization of the algal biomass after pretreatments involved scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). The highest methane yields of 240 (28) and 250 (20) NLCH4 kg-1 VSadded were obtained with the new mechanical pretreatment and the thermal pretreatment at 120 °C for 45 min without zeolite, achieving a 35 % improvement against the non-pretreated algae. A direct relationship between the crystallinity index of the samples and methane production was observed. The experimental data of methane production versus time were found to be in accordance with both first-order kinetic and Transference Function mathematical models.

Estudio sociodemográfico comparativo de los períodos 2007-2009 y 2015-2019 de la Unidad de Tratamiento de Identidad de Género del Principado de Asturias / Sociodemographic comparative between the periods 2007-2009 and 2015-2019 of the Gender Identity Treatment Unit of Asturias

Antecedentes y objetivo: La elevada demanda asistencial sanitaria realizada por las personas trans en los últimos años ha dirigido el foco de la investigación hacia el estudio de sus aspectos clínicos y sociodemográficos. Este trabajo tuvo por objetivo comparar y analizar algunas variables sociodemográficas en personas trans en 2 períodos temporales: el período de inicio de funcionamiento de la unidad y el período más reciente. Materiales y método: Se comparó una muestra de 131 usuarios que asistió a la Unidad de Tratamiento de Identidad de Género del Principado de Asturias (UTIGPA) entre 2015-2019, con una muestra de 33 que acudió entre 2007-2009. Los datos se extrajeron de historias clínicas. Resultados: Respecto al período 2007-2009 entre 2015-2019 la ratio se invierte a favor de los hombres trans (HT). Los usuarios de ambos géneros solicitan consulta a edades más tempranas (especialmente los HT), provienen menos del extranjero, alcanzan una mayor cualificación educativa y laboral, presentan menos paro y solicitan más el cambio registral; y aunque las mujeres trans (MT) continúan siendo las que, mayoritariamente, se dedican a la prostitución y se autohormonan, en este período más reciente lo reportan menos y, además, conviven más acompañadas. Conclusiones: Se observan cambios en las variables sociodemográficas de los usuarios de la UTIGPA entre 2007-2009 y 2015-2019, en dirección a una mayor inclusión. No obstante, las condiciones sociodemográficas de las MT siguen en desventaja en comparación con las de los HT. (AU)

Background and objective: The high demand of assistance made by trans people in recent years has directed the focus of research towards the study of their clinical and sociodemographic aspects. The objective of this work was to compare and analyze some sociodemographic variables in trans people in two periods: the period when the unit began to operate and the most recent period. Materials and method: A sample of 131 users who attended the Gender Identity Treatment Unit of the Principality of Asturias (UTIGPA) between 2015-2019 was compared with a sample of 33 who attended between 2007-2009. Data were extracted from medical records. Results: Regarding 2007-2009, in 2015-2019 the ratio is inverted in favor of Trans Men (TM). Users of both genders request consultation at an earlier age (specially TM), come less from abroad, achieve higher educational and work qualifications, are less unemployed and request more name changes. And, although Trans Women (TW) continue to be those who are mostly engaged in prostitution and self-administration of hormones, in the most recent period they report it less and, furthermore, they live more accompanied tan in the past. Conclusions: Changes are observed in the sociodemographic variables of UTIGPA users between 2007-2009 and 2015-2019, in the direction of a greater inclusion. However, the sociodemographic conditions of the TW are still at a disadvantage in comparison to those of the TM. (AU)

Integral Valorization of Two-Phase Olive Mill Solid Waste (OMSW) and Related Washing Waters by Anaerobic Co-digestion of OMSW and the Microalga Raphidocelis subcapitata Cultivated in These Effluents.

This study evaluates the comprehensive valorization of the byproducts derived from the two-phase olive oil elaboration process [i.e., olive washing water (OWW), olive oil washing water (OOWW), and olive mill solid waste (OMSW)] in a closed-loop process. Initially, the microalga Raphidocelis subcapitata was grown using a mixture of OWW and OOWW as the culture medium, allowing phosphate, nitrate, sugars, and soluble chemical oxygen demand removal. In a second step, the microalgal biomass grown in the mixture of washing waters was used as a co-substrate together with OMSW for an anaerobic co-digestion process. The anaerobic co-digestion of the combination of 75% OMSW-25% R. subcapitata enhanced the methane yield by 7.0 and 64.5% compared to the anaerobic digestion of the OMSW and R. subcapitata individually. This schedule of operation allowed for integration of all of the byproducts generated from the two-phase olive oil elaboration process in a full valorization system and the establishment of a circular economy concept for the olive oil industry.

Evaluation and modelling of methane production from corn stover pretreated with various physicochemical techniques.

Lignocellulosic by-products from agricultural crops represent an important raw material for anaerobic digestion and clean renewable, which is a key component of the circular economy. Lignocellulose is recalcitrant to biodegradation and pretreatments are required to increase methane yield during anaerobic digestion. In this work, the efficacy of different physicochemical pretreatments was compared using corn stover biomass as substrate. Anaerobic digestion of untreated and pretreated corn stover was performed in batch mode at mesophilic temperature (38°C) and organic matter solubilization of pretreated substrates was also investigated. The highest organic matter solubilization occurred in autoclave pretreatment (soluble chemical oxygen demand = 5630 ± 42 mg O2 L-1). However, the highest methane yield was obtained using alkaline pretreatment (367 ± 35 mL CH4 g-1 VSadded). Alkaline pretreatment increased methane yield by 43.3% compared to untreated control (256 ± 15 mL CH4 g-1 VSadded). Two mathematical models (i.e. first-order kinetics and transfer function) were utilized to fit the experimental data with the aim of assessing anaerobic biodegradation and to obtain the kinetic constants in all cases studied. Both models adequately fit the experimental results. The kinetic constant, k, of the first-order model increased by 92.8% when stover was pretreated with sulphuric acid compared with control. The transfer function model revealed that the maximum methane production rate, Rm, was obtained for the sulphuric acid treatment, which was 63.5% higher compared to control.

Farmacias comunitarias de Ecuador y España. Aspectos legales / Ecuador and Spain community pharmacies. Legal aspects

INTRODUCCIÓN: La necesidad de estándares de calidad de los servicios farmacéuticos, para garantizar el uso seguro, responsable y efectivo del medicamento, ha hecho que a través de los años se produzcan una serie de cambios en los sistemas sanitarios. Existe además, una lucha para posicionar a la farmacia y a farmacéuticos como ejes potenciales para promulgar la protección de la salud. Fruto de estos cambios, se evidencian diferencias estructurales en los modelos de farmacia entre países desarrollados y países en vías de desarrollo. El presente estudio realiza un análisis comparativo del modelo de oficina farmacia entre los países de Ecuador y España, diferenciando las legislaciones alusivas al funcionamiento de las farmacias y comparando los modelos de oficina de farmacia. MÉTODO: Estudio comparativo basado en investigación documental, en lo referente a normativas y legislación de las farmacias comunitarias de Ecuador y España. RESULTADOS: En el presente trabajo se analizan la legislación vigente que regula la farmacia española y ecuatoriana, en referencia al establecimiento de nuevas farmacias, propiedad farmacéutica, prohibición de cadenas de farmacia, así como la calidad de la formación del farmacéutico comunitario. CONCLUSIONES: En países de Latinoamérica, como en el caso de Ecuador, la farmacia adopta un modelo más liberal, refiriendo a la desregularización de la apertura de nuevas farmacias, temas de propiedad, sistema de planificación territorial, así como la no presencia del profesional farmacéutico; dando lugar a un sistema con un fuerte enfoque comercial; incidiendo de esta forma sobre la función ideal que debe llevar a cabo la farmacia comunitaria

INTRODUCTION: The need for quality standards in pharmaceutical services, that provides a safety, responsible and effectiveness use of medication, has led several changes in health systems over the years. There is also a struggle to position the pharmacy and pharmaceutical professionals as potential axes to enact health care. As a result of these changes, there are structural differences in pharmacy models between developed and developing countries. The present study sets out to provide a comparative analysis of Ecuador and Spain pharmacy office model, differentiating legislations concerning the functioning of pharmacies and comparing the pharmacy office models. METHOD: Documentary based research and a comparative study, regarding regulations and legislation of community pharmacies in Ecuador and Spain. RESULTS: In this paper, the current legislation that regulates the Spanish and Ecuadorian pharmacy is analyzed, in reference to the establishment of new pharmacies, pharmaceutical ownership, prohibition of pharmacy chains, as well as the quality of the training of community pharmacists. CONCLUSIONS: In Latin American countries, as in the case of Ecuador, the pharmacy adopts a more liberal model, referring to the deregulation of the opening of new pharmacies, property issues, territorial planning system, as well as the non-presence of the professional pharmacist; resulting in a system with a strong commercial focus; thus emphasizing the ideal role to be played by the community pharmacy

[Sex/gender ratio of adolescents with gender dysphoria of the Gender Identity Treatment Unit of Asturias]. / Ratio sexo/género de los adolescentes con disforia de género de la Unidad de Tratamiento de Identidad de Género de Asturias.

BACKGROUND AND OBJECTIVE: Demand from minors with complaints of gender dysphoria has increased in recent years. This increase has been more pronounced in adolescent trans men in some international research studies. The first objective of this research study was to determine the sex/gender ratio of minors requesting a consultation in the Gender Identity Treatment Unit of the Principality of Asturias (UTIGPA) and presenting complaints of gender dysphoria. The second objective was to analyse the relationship of the sex/gender ratio with the age variable at which they requested the first consultation and the year in which they requested it. MATERIALS AND METHOD: The sample consisted of 42 children under 18, attended between January 2016 and January 2019. The medical records were then reviewed to obtain information. Descriptive statistics were analysed with the collected data. RESULTS: The sex / gender ratio over the period was 2/1 in favour of trans men. The average age at the request for consultation was 15.02 years (SD=1.84), with a range of 6 to 17 years. A higher percentage of applications was recorded (35.7%) in 2018, mostly made by trans men (93.3%). CONCLUSIONS: There was an inversion of the sex/gender ratio, a favour of trans men, over the last 3years, and an increase in the number of applications by adolescent trans men, coinciding with several international investigations.

[New care models for transgender people in the Spanish Health System: demands, controversies and reflections.] / Nuevos modelos de atención sanitaria para las personas transgénero en el Sistema Sanitario Español: demandas, controversias y reflexiones.

Health care for transgender people in Spain has been progressively established since 1999 when the first multidisciplinary unit for the treatment of sex reassignment was created in Andalusia. In this document, the social changes, the demands and debates of users and professionals, the new models of health care for trans people, and reflections on the current situation, have been analysed. The social openness in Spain regarding sexual and gender diversity has evolved quite positively. The health demands of the transgender users are not uniform and do not always match with the criteria of the professionals. In some Spanish regions, health care is distancing itself from the internationally recommended multidisciplinary model. The new healthcare models have been established under the aegis of primary care and/or endocrinologist in the area, without a required psychological assessment. The main contributing factors for this change of model have been the pressure from some associations with demands for "depathologization" and "decentralization". The professionals of gender units, while recognizing the need for a broader vision of trans reality, warn of the risk of treating trans people without the involvement of mental health specialists or by professionals in proximity with little experience. Moreover, the decentralization would not allow acting on large cohorts, which hinders the advance of knowledge and contrasted evaluations with neighbouring countries. In summary, the new health models, although intended to facilitate care through proximity, do not guarantee improvements in quality and difficult to make a comparative evaluation of the results.

La atención sanitaria a las personas transgénero en España se ha establecido de manera progresiva desde 1999, año en que Andalucía crea la primera unidad multidisciplinar para el tratamiento integral de la reasignación de sexo. Este documento analiza los cambios sociales, las demandas y debates entre usuarios y profesionales y los nuevos modelos de atención sanitaria, y también plantea reflexiones sobre la situación actual. La apertura social en España en la concepción de la diversidad sexual y de género es bastante favorable. Las demandas de los usuarios no son uniformes y no siempre coinciden con los criterios de los profesionales. En algunas comunidades autónomas la asistencia sanitaria se está distanciando del modelo recomendado internacionalmente, que basa la atención en equipos especializados o Unidades de Identidad de Género (UIG). Estos nuevos modelos centran la asistencia en la Atención Primaria, además de en endocrinólogos y pediatras de área sin una evaluación coordinada con Salud Mental. Los principales factores contribuyentes al cambio reciente han sido las demandas desde algunas asociaciones de "despatologización" y "descentralización". Estos nuevos modelos centran la asistencia en la Atención Primaria, además de en endocrinólogos y pediatras de área sin una evaluación coordinada con Salud Mental. Los profesionales que integran las unidades de género, si bien reconocen la necesidad de una visión amplia de la realidad transgénero, alertan del riesgo que supone tratar a personas trans sin una colaboración de especialistas en Salud Mental o por profesionales de área con escasa experiencia. Además, anticipan que la descentralización no facilita el estudio de grandes cohortes, dificultando el avance del conocimiento y la evaluación contrastada con países del entorno. En resumen, los nuevos modelos sanitarios, aunque ofrecen la atención en proximidad, no garantizan mejoras en la calidad ni promueven el análisis comparado de los resultados.

Apnea during slow sub-anaesthetic infusion of intravenous ketamine for treatment-resistant depression.

Ketamine's pharmacological profile makes it an interesting and useful drug to challenge treatment-resistant-depression (TRD). Emerging adverse events associated with single-slow-sub-anaesthetic doses for the treatment of depression are common, although generally transient and self-limited. Nevertheless, data on the safety of this practice are scarce. Thus, it seems timely before ketamine is used for clinical treatment of depression to recommend careful monitoring and reporting of all potential adverse events related to ketamine administration. Here, we describe a case of apnea during slow sub-anaesthetic infusion of intravenous ketamine for the treatment of resistant depression. As far as we are concerned, this is an uncommon, previously unreported, and potentially severe adverse event that clinicians should be aware of, and specific management measures should be implemented.

Nuevos modelos de atención sanitaria para las personas transgénero en el sistema sanitario español: demandas, controversias y reflexiones / New care models for transgender people in the Spanish Health System: demands, controversies and reflections

La atención sanitaria a las personas transgénero en España se ha establecido de manera progresiva desde 1999, año en que Andalucía crea la primera unidad multidisciplinar para el tratamiento integral de la reasignación de sexo. Este documento analiza los cambios sociales, las demandas y debates entre usuarios y profesionales y los nuevos modelos de atención sanitaria, y también plantea reflexiones sobre la situación actual. La apertura social en España en la concepción de la diversidad sexual y de género es bastante favorable. Las demandas de los usuarios no son uniformes y no siempre coinciden con los criterios de los profesionales. En algunas comunidades autónomas la asistencia sanitaria se está distanciando del modelo recomendado internacionalmente, que basa la atención en equipos especializados o Unidades de Identidad de Género (UIG).

Health care for transgender people in Spain has been progressively established since 1999 when the first multidisciplinary unit for the treatment of sex reassignment was created in Andalusia. In this document, the social changes, the demands and debates of users and professionals, the new models of health care for trans people, and reflections on the current situation, have been analysed. The social openness in Spain regarding sexual and gender diversity has evolved quite positively. The health demands of the transgender users are not uniform and do not always match with the criteria of the professionals. In some Spanish regions, health care is distancing itself from the internationally recommended multidisciplinary model. The new healthcare models have been established under the aegis of primary care and/or endocrinologist in the area, without a required psychological assessment. The main contributing factors for this change of model have been the pressure from some associations with demands for "depathologization" and "decentralization". The professionals of gender units, while recognizing the need for a broader vision of trans reality, warn of the risk of treating trans people without the involvement of mental health specialists or by professionals in proximity with little experience. Moreover, the decentralization would not allow acting on large cohorts, which hinders the advance of knowledge and contrasted evaluations with neighbouring countries. In summary, the new health models, although intended to facilitate care through proximity, do not guarantee improvements in quality and difficult to make a comparative evaluation of the results
