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.

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.

The influence of gender roles in alcohol consumption: a qualitative study of adolescents and young adults in Asturias. / La influencia de los roles de género en el consumo de alcohol: estudio cualitativo en adolescentes y jóvenes en Asturias.

Despite the implementation of prevention policies aimed at addressing alcohol consumption among both adolescents and young adults, there has been a considerable increase in those who abuse alcohol in Spain over the last decade. Official surveys on this phenomenon show that both the prevalence and risky consumption of men and women are reaching similar levels, with even higher figures for these behaviours in the case of girls at the end of adolescence. The aim of this article is to understand the influence of gender roles in the consumption of alcohol among adolescents and young adults. To this end, focus groups have been employed to identify similarities and differences both in drinking patterns and alcohol abuse among young males and females, as well as in the social meaning that both groups attribute to these practices.   The results obtained show that the variables gender and age act in a combined way on the learning of alcohol consumption, as well as on the motivations and expectations that adolescents and young adults have regarding these practices. In addition, in this study three differentiated stages are identified: in the first, gender roles are clearly defined; in the second, there is a certain transgression of these roles mainly by young women, and in the third, there is a return to traditional gender roles.

A pesar del desarrollo de políticas de prevención dirigidas a abordar el consumo de alcohol en adolescentes y jóvenes, durante la última década se ha producido un aumento considerable de quienes realizan un consumo abusivo de esta sustancia en España. Las encuestas oficiales sobre este fenómeno muestran un acercamiento entre varones y mujeres en las prevalencias de consumo y en los consumos de riesgo, e incluso una mayor incidencia de estas conductas en el caso de las mujeres al final de la etapa adolescente. El objetivo de este artículo es conocer la influencia que ejercen los roles de género en estas pautas de consumo en adolescentes y jóvenes. Para ello, se han realizado grupos focales que han permitido identificar las similitudes y diferencias que se producen tanto en las prácticas de consumo y abuso del alcohol que desarrollan estos colectivos, como en el significado social que unos y otras atribuyen a las citadas prácticas.  Los resultados obtenidos muestran que las variables género y edad actúan de forma combinada en el aprendizaje del consumo de bebidas alcohólicas, así como en las motivaciones y expectativas que los y las adolescentes y jóvenes tienen sobre dichas prácticas. Además, en este estudio se identifican tres etapas diferenciadas, en la primera de ellas los roles de género se encuentran claramente definidos, en la segunda se observa cierta transgresión de los mismos fundamentalmente por parte de las mujeres y en la última se advierte una vuelta a los tradicionales roles de género.

Selective decontamination of the digestive tract in a burns unit reduces the incidence of hospital-acquired infections: A retrospective before-and-after cohort study.

OBJECTIVE: To evaluate the effect of selective decontamination of the digestive tract (SDD) on hospital-acquired infections (HAIs) in patients with acute burn injury requiring admission to a Burns Unit (BU). DESIGN: Retrospective before-and-after cohort study, between January 2017 and June 2023. SDD was implemented in March 2019, dividing patients into two groups. SETTING: Four-bed BU, in a referral University Hospital in Spain. PATIENTS: All the patients admitted during the study period were eligible for analysis. Patients who died or were discharged within 48hours of admission, and patients with an estimated survival less than 10% not considered for full escalation of therapy were excluded. INTERVENTION: SDD comprised the administration of a 4-day course of an intravenous antibiotic, and an oral suspension and oral topical paste of non-absorbable antibiotics during the stay in the BU. MAIN VARIABLE OF INTEREST: Incidence of HAIs during the stay in the BU. SECONDARY OUTCOMES: incidence of specific types of infections by site (bacteremia, pneumonia, skin and soft tissue infection) and microorganism (Gram-positive, Gram-negative, fungi), and safety endpoints. RESULTS: We analyzed 72 patients: 27 did not receive SDD, and 45 received SDD. The number of patients who developed HAIs were 21 (77.8%) and 21 (46.7%) in the non-SDD and the SDD groups, respectively (p=0.009). The number of hospital-acquired infectious episodes were 2.52 (1.21-3.82) and 1.13 (0.54-1.73), respectively (p=0.029). CONCLUSIONS: SDD was associated with a reduced incidence of bacterial HAIs and a decrease in the number of infectious episodes per patient.

Repair of long-bone pseudoarthrosis with autologous bone marrow mononuclear cells combined with allogenic bone graft.

BACKGROUND AIMS: Long-bone pseudoarthrosis is a major orthopedic concern because of numerous factors such as difficulty of the treatment, high recurrence, high costs and the devastating effects on the patients' quality of life, which sometimes ends in amputation. Although the "gold standard" for the treatment of this pathology is autologous bone grafting, which has high osteogenic, osteoconductive and osteoinductive properties, this treatment presents some restrictions such as the limited amount of bone that can be taken from the patient and donor site morbidity. Bone marrow mononuclear cells (BM-MNCs) comprise progenitor and stem cells with pro-angiogenic and pro-osteogenic properties. Allogenic cancellous bone graft is a natural and biodegradable osteoconductive and osteoinductive scaffold. Combination of these two components could mimic the advantages of autologous bone grafting while avoiding its main limitations. METHODS: Long-bone pseudoarthrosis was treated in seven patients with autologous BM-MNCs from iliac crest combined with frozen allogenic cancellous bone graft obtained from the tissue bank. RESULTS: All patients showed complete bone consolidation 5.3 ± 0.9 months (range, 2-9 months) after cell transplantation. Moreover, limb pain disappeared in all of them. The mean follow-up was 35.8 ± 4.6 months after transplantation (range, 24-51 months) without pseudoarthrosis recurrence or pain reappearing. CONCLUSIONS: Combination of autologous BM-MNCs and allogenic bone graft could constitute an easy, safe, inexpensive and efficacious attempt to treat long-bone pseudoarthrosis and non-union by reproducing the beneficial properties of autologous bone grafting while restricting its disadvantages.

Adipose tissue concentrations of persistent organic pollutants and prevalence of type 2 diabetes in adults from Southern Spain.

There is increasing evidence that environmental factors play an important role in the development of type 2 diabetes. Several persistent organic pollutants are suspected to contribute to the increasing prevalence and risk of type 2 diabetes. The aim of this study was to investigate the association of the body burden of three organochlorine pesticides and three polychlorinated biphenyls and the overall estrogenic activity with the risk of type 2 diabetes in a sample of adults from Southern Spain. Samples of adipose tissue and serum were obtained from 386 subjects undergoing non-cancer-related surgery and were extracted using validated methodologies. Residues of persistent organic pollutants were analyzed by means of high-resolution gas chromatography with a mass spectrometry detector in tandem mode. The overall estrogenicity of the adipose tissue extracts was measured by using the total effective xenoestrogen burden (TEXB) biomarker. Data on lifestyle, dietary habits, and health status were gathered from face-to-face interviews and clinical records. Statistical analyses were performed with unconditional logistic regression and different adjustment levels. In the models adjusted for adipose tissue origin, sex, age, and body mass index, the 2nd and 3rd tertiles of adipose tissue concentrations of p,p'-dichlorodiphenyldichloroethylene (p,p'-DDE) were positively associated with the risk of diabetes [odds ratios (95% confidence interval)=3.6 (0.8-17.3) and 4.4 (1.0-21.0), respectively]. A positive association with ß-hexachlorocyclohexane was also found when body mass index and adipose tissue origin were removed from the models, with odds ratios (95% confidence interval) of 3.3 (1.0-10.4) and 5.5 (1.7-17.3), for the 2nd and 3rd tertiles of exposure, respectively. In addition, a statistically significant interaction was observed between p,p'-DDE and body mass index, such that the risk of diabetes increased with tertiles of exposure in a linear manner in non-obese subjects but not in the obese, in whom an inverted U-shape pattern was observed.

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.

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.

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.

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.

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.

[Gender dysphoria in trans minors: Ecological niche]. / La disforia de género en menores trans: nicho ecológico.

BACKGROUND AND OBJECTIVE: The objective of the present study is to investigate the contextual characteristics of the onset of gender dysphoria (GD) in trans minors. MATERIALS AND METHOD: All minors who requested consultation in the Gender Identity Treatment Unit from March 2007 to June 2019 participated. Clinical histories were reviewed to obtain the information. Confidentiality was guaranteed. RESULTS: Sixty-four minors required care, 39.1% were trans women (TW) and 60.9% trans men (TM). The age range was between 6-17 years, with a mean of 14.98. Seventy-five percent of the trans minors located the onset of DG in childhood and 25% in adolescence. Parental reaction was suspicious in 55.6% of cases and surprise in 36.5%; 55.6% presented significant psychological distress before going to the unit. Family support was present in 57.1%. The role of social networks and the Internet was relevant for 39.7% of the sample. Of the minors, 44.4% had membership or contact with peer groups or LGTBIQ associations. Results were analysed according to sense of gender. CONCLUSIONS: Minors continue to require care in the units, especially TW. Although GD onset in both groups is mainly in childhood, in adolescence it is more frequent in TM. Trans minors are born, develop and build their identity in a specific context, which is in interaction.

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

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.

[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.

COVID-19: Critical appraisal of the evidence.

We present the summary of a critical appraisal document of the available evidence on COVID-19, developed with a clinical practice guide format following GRADE methodology. The document tries to provide answers to a series of structured clinical questions, with an explicit definition of the population, intervention / exposure, comparison and outcome, and a rating of the clinical relevance of the outcome measures. We conducted a systematic review of the literature to answer the questions, grouped into six chapters: epidemiology, clinical practice, diagnosis, treatment, prevention, and vaccination. We assessed the risk of bias of the selected studies with standard instruments (RoB-2, ROBINS-I, QUADAS and Newcastle-Ottawa). We constructed evidence tables and, when necessary and possible, meta-analysis of the of the most relevant outcome measures. We followed the GRADE system to synthesise the evidence, assessing its quality, and, when appropriate, giving recommendations, rated according to the quality of the evidence, the values and preferences, the balance between benefits, risks and costs, equity and feasibility.

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.

[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.

Domain and intensity of physical activity are associated with metabolic syndrome: A population-based study.

INTRODUCTION: Little is known on how the domain and intensity of physical activity (PA) associates with metabolic syndrome (MetS). The aim of this study was to examine associations between PA domains (leisure-time, domestic, active transport, total walking and total PA), PA intensities (light, moderate and vigorous) and PA levels with MetS in the general adult population. METHODS: Cross-sectional study. Anthropometry, blood biochemistry, 79-item PA-questionnaire, lifestyle and medical history were evaluated in a representative sample of Canary Island adults (n = 6,729). MetS was diagnosed using the harmonized IDF-NHLBI-AHA criteria. T-test and multivariable logistic regression was used to analyse associations between PA domains and intensities with MetS vs. no MetS, controlling for socio-demographic, lifestyle, family antecedents and body mass index (BMI). RESULTS: For each MET-h/day spent in moderate-vigorous PA intensities, as well as in recreational domain, active transport, total walking and total PA, the odds of MetS decreased between 3-10%. Energy expenditure exclusively in light and domestic PAs was not associated with MetS, however it was important to achieve a total PA level of 3 MET-h/day, which reduced the odds of MetS by 23%. This reduction was blunted in those with more than 2 h/d of TV watching time. A PA level of 3 MET-h/d also nullified the risk of MetS in those with low PA and high TV consumption. CONCLUSIONS: Some types of leisure time PAs may contribute more than others to reducing MetS. Light and domestic PA play a complementary role in enhancing energy expenditure in the general population. TV watching time above 2 h/d counteracted the MetS risk reduction associated with PA level, but PA level also reduced the risk of METs presented by those with a low level of PA and an excess TV watching time. Physical activity explains a greater amount of the variance of MetS than any other factors of lifestyle, education, sex and family history, and substantially mitigates the strong association of age and BMI with MetS.

Table Olive Wastewater: Problem, Treatments and Future Strategy. A Review.

The table olive industry produces a high quantity of wastewater annually. These wastewaters are very problematic because of their characteristics of high organic matter, high phenolic content, high salinity and conductivity. The quantities in which they are produced are also a serious problem. The worldwide production of table olives reached 2,550,000 tons in the last five campaigns, with the European Union contributing to 32% of total production. The problem of these wastewaters is focused on the Mediterranean area where the highest quantity of table olives is produced and to a lesser extent on the United States and South America. Countries like Spain produce around 540,000 tons of these wastewaters. At present, there is no standard treatment for these wastewaters with acceptable results and which is applied in the industry. Currently, the most common treatment is the storage of these wastewaters in large evaporation ponds where, during the dry season, the wastewater disappears due to evaporation. This is not a solution as the evaporation ponds depend completely on the climatology and have a high number of associated problems, such as bad odors, insect proliferation and the contamination of underground aquifers. Different studies have been carried out on table olive wastewater treatment, but the reality is that at the industrial level, none has been successfully applied. New and promising treatments are needed. The current review analyzes the situation of table olive wastewater treatment and the promising technologies for the future.
