RESUMO

Potential pollution of mining environmental liabilities' locations can be preliminarily and efficiently assessed by the potential generation of acid mine drainage and indices of contamination. This research evaluates the potential pollution by potentially toxic elements at locations with uranium mining liability evidence, using the net acid generation test and determining the background values to estimate acid mine drainage and indices of contamination. Sixty soil samples were collected, and the mineralogy and potentially toxic elements' total contents were determined by x-ray diffraction and optical spectrometry. The findings suggest that the soils related to a specific lithology might not present potential acid mine drainage generation but potential soil and sediment contamination. Future research is recommended on applying leaching tests to identify which potentially toxic elements are effectively being solubilized. Finally, it can be concluded that the study area's potential contamination is relatively low overall.

RESUMO

Wild edible plants have played an important role in traditional diets, including the Mediterranean diet. Many of these plants have acquired an undervalued status, since they are under-appreciated in terms of their nutritional, organoleptic qualities, or their seasonality. However, some of these species are still used in local gastronomy for their aromatic and taste characteristics. This study has investigated the quantitative and qualitative aromatic characteristics of seven undervalued wild plants that determine their organoleptic characteristics. Volatiles of the fresh leaves of each species have been determined by head-space solid-phase microextraction, a sensitive and solvent-free technique, coupled with gas chromatography and mass spectrometry. A total of 37 compounds with remarkable quantitative and qualitative differences were identified. In general, benzenoids and monoterpenoids were the most abundant groups, while branched unsaturated hydrocarbons, fatty alcohols, and sesquiterpenoids were the minor groups. Benzyl nitrile, benzyl isothiocyanate, p-cymene, and 2-hexenal were the main individual volatiles, while benzyl alcohol, eugenol, and α-copaene were the differentiating aromas. The results display that the undervalued species studied could be a suitable choice to include as new environmentally friendly crops, providing a double benefit to producers, because they are a possible way to achieve sustainable production systems, and they are an alternative for consumers, because these plants provide flavors that have high organoleptic qualities.

RESUMO

Wild edible plants are an important source of healthy food and have played an important role in traditional Mediterranean diets. In this paper, quality characteristics were typified in Portulaca oleracea L. and Porophyllum ruderale (Jacq.) Cass, undervalued plants inherent to the spring-summer season in the Valencian coastal region. Nutritional composition and bioactive compounds were analyzed and compared between plants in wild and organic cultivation conditions. Proximate analysis was carried out according to Association of Official Analytical Chemists methods. Total antioxidants were measured as 2.2-diphenyl-1-picrylhydrazyl hydrate and total polyphenols content via the Folin-Ciocalteu procedure. The HS-SPME technique was used to characterize the volatiles profile, and the polyphenol profile was evaluated by HPLC. The most important microelement was iron. Total antioxidants ranged from 4392.16 to 7315.00 µmol Trolox·equivalents 100 g-1 fw, and total phenolic content ranged from 99.09 to 391.18 mg gallic acid equivalents·100 g-1 fw. Results show that the content of antioxidants and phenols was higher in wild species than in cultivated ones. The volatiles profile revealed that P. ruderale was rich in monoterpenoids (48.65-55.82%), and fatty alcohols were characteristic in P. oleracea species (16.21-54.18%). The results suggest that both plants could be healthy foods and could have new sustainable agro-ecological potential for the local commercial sector.

RESUMO

BACKGROUND: Wild edible herbs have historically been used as local nutritional and medicinal sources. These plants grow spontaneously, depending on the season. They adapt well to different edaphoclimatic conditions, generating a diversity constituent beneficial to health. They impart compounds needed in the human diet in regard to macro and micronutrients. When consumed raw, they keep their properties intact and provide health benefits. Five undervalued edible plants: Stellaria media (L.) Vill, Tropaeolum majus L., Sonchus oleraceus L., Chenopodium album L. and Diplotaxis erucoides (L.) DC are characteristic of the autumn-winter season in the Valencian coastal region and could have new sustainable agro-ecological potential for the local commercial sector. However, little information is available from the nutritional quality and bioactive composition viewpoint for these species. Concurrently, the volatiles compounds profiles describing the characteristic flavors are unknown. METHODS: Nutritional characteristics, bioactive compounds, and other chemical components of the fresh leaves were analyzed. In addition, the volatiles composite profile was performed. The analyzed species come from the soil reservoir; their wild growth is adjusted to the autumn season. The proximate analysis was carried out by Association of Official Analytical Chemists methods. Total antioxidants were measured as 2.2-diphenyl-1-picrylhydrzyl hydrate (DPPH) and total polyphenols content via the Folin-Ciocalteu procedure. Volatiles profile was determined by gas chromatography-mass spectrometry. The vegetative part analyzed was the tender leaves with edible potential. RESULTS: A high variability has been obtained in the composition of the species studied. The proximate analysis found a considerable content of fiber (1.22-5.4 g·100 g-1), potassium (157.7-1,250.6 mg·100 g-1), iron (0.6-2.0 mg·100 g-1), and a low caloric value (16.1-43.02 kcal·mg·100 g-1). In bioactive compounds analysis, a high level of antioxidants was highlighted (1,604.3-4,874.6 µmol·100 g-1), followed by chlorophylls. Volatiles profile revealed that the species were rich in benzenoids (33.8-89.9%) as the majority family. The pyrazines class was characteristic only in D. erucoides L. DISCUSSION: Fresh edible leaves of the undervalued plants show considerable nutritional potential and a high bioactive components level, which highlight the antioxidant capacity. Leaves of C. album L. stand out due to their higher concentration of nutritional compounds, while D. erucoides L. is noted for its higher antioxidant capacity. Aromatic descriptor of pyrazines detected in the leaves of D. erucoides L. is associated with the slightly spicy flavors that characterize this species. Results suggest that studied species could be of great relevance in introducing these five edible herbs as a source of new grown material, postulating them as healthy food ingredients with attractive flavors for the gourmet cuisine industry.

RESUMO

Mining operations are important causes of environmental pollution in developing countries where mining waste management is not adequate. Consequently, heavy metal(loid)s are easily released into the environment, being a potential risk to human health. This study carries out a Bayesian probabilistic human health risk assessment, related to multi-pathway exposure to heavy metal(loid)s in a gold mining area in Southern Ecuador. Concentrations of As, Cd, Cr, Cu, Ni, Pb, and Zn in tap water, surface water, and soil samples, were analyzed to assess the potential adverse human health effects based on the Hazard Index (HI) and Total cancer risk (TCR). Adults and children residents were surveyed to adjust their exposure parameters to the site-specific conditions. Exposure to heavy metal(loid)s resulted in unacceptable risk levels for human health in the two age groups, both carcinogenic (TCR > 1 × 10-5) and non-carcinogenic (HI > 1) through ingestion of tap water and incidental ingestion of surface water. Sensitivity analysis showed that As concentration in waters and exposure frequency were the main contributors to risk outcome. Exposure to soil via accidental ingestion and dermal contact was below the safety limit, not posing a risk to human health. These findings can provide a baseline for the environmental management of the mining area and indicate the need for further research on As pollution in water and its implications on the health of the inhabitants of mining communities.

RESUMO

Gold mining is a significant source of metal(loid)s released into the environment. It is an issue of concern due to the potential adverse health effects associated with exposure to toxic elements. This study aimed to assess the ecological and human health risk caused by heavy metal(loid)s exposure in river sediments in Ponce Enríquez, one of the most important mining sites in Ecuador. Concentrations of As, Cd, Cu, Pb, and Zn were evaluated in 172 sediment samples to determine the Potential ecological risk (RI) and the carcinogenic (CR) and non-carcinogenic risk (HQ). The human exposure to polluted sediments during recreational activities was computed using Bayesian probabilistic models. Residents were randomly surveyed to adjust the risk models to the specific population data. More than 68% of the sampling stations pose a severe As and Cd ecological risk index ([Formula: see text] > 320). Likewise, residents exposed to river sediments showed a non-acceptable carcinogenic risk by incidental ingestion, being As the primary contributor to overall cancer in both children and adults receptors. Moreover, non-carcinogenic risk through the incidental ingestion of sediments was above the safe limit for children. This is the first study conducted in a mining region in Ecuador that reveals the severe levels of ecological and human health risk to which the population is exposed. These results can be applied as a baseline to develop public health strategies to monitor and reduce the health hazards of the residents of mining communities.

RESUMO

Potentially toxic elements (PTEs) present in abandoned mining wastes (AMW) are of great concern because of potential risks to human health and ecosystems. Indices of contamination (IC) applied to mining wastes are calculated using the total concentration of PTEs and comparing them with regional geochemical backgrounds. However, determining the total content of heavy metals is insufficient to assess the hazard of mining wastes. Therefore, in addition to total concentration, the potential risk is also evaluated through water mobility of elements. Accordingly, leaching procedures are useful tools for the geochemical characterization of soluble constituents that are mobilized. In this study, the solubility of PTEs from different types of mining wastes is comparatively assessed using three standard leaching methods (European; U.S. Geological Survey and; Mexican). The Hazard Average Quotient (HAQ) was calculated to assess the potential Toxicity Factor (TF). TF is an indicator of the relative potential toxicity of wastes and is the basis for the classification of AMW. A comparative assessment provides evidence that there are no statistically significant differences in PTEs solubility by the three leaching methods and it was also found that the pH of the eluates was dictated by the type of waste. Results suggest that the IC gives an indicator of the potential contamination of soils and sediments by erosive processes, or a long-term measure, whereas TF assesses the possibility of contaminating water in the short term. The most significant finding is the new ranking scale of TF, as a function of HAQ, applied to the Mexican standard leaching test. This factor, together with other considerations relating to risk-generating processes, might then be applied in places having large amounts of recorded AMW, such as the Iberian Peninsula and Latin America, where effective management is required to rank sites, based on preliminary environmental and human risk assessment.

RESUMO

Las Enfermedades vectoriales, impulsan la responsabilidad social de las instituciones de Educación Superior, sensibilizando al estudiante en formación, hacia la promoción de salud en atención a las poblaciones más vulnerables. El diseño de materiales bioeducativos como actividad asociada a la Sala Lúdica que permite ofrecer una acción integradora ante la deserción estudiantil del sector universitario, quienes al enfrentar una maternidad/paternidad durante su escolaridad corren el riesgo de abandonar sus carreras.Ni las universidades ni el Estado cuentan con infraestructura, políticas, estatutos que permitan brindar el apoyo necesario. Por lo que se propuso al determinar la deserción de madres/padres universitarios de la carrera de Enfermería de la Universidad de Guayaquil verificar la implementación de la Sala Lúdica como un eje integrador que desde la promoción de salud atienda la deserción estudiantil. Se realizó un estudio de tipo cuantitativo, experimental, con enfoque descriptivo y cohorte restrospectivo. La muestra estuvo conformada por 169 estudiantes matriculados. Se observó una distribución de frecuencia de 24% graduados, 43% desertores y 34% repitientes, dentro del grupo de repitientes, la causa de mayor frecuencia fue el cuidado de hijos en 31%. El porcentaje de disposición para la utilización del servicio de Sala lúdica fue de 90%, con un 73% de aceptación del diseño de materiales bioeducativos para la prevención de las enfermedades vectoriales, resultando el dengue con una incidencia del 87% como temática. Igualmente, un 84% de los desertores retomarían sus estudios. Como conclusión una Sala Lúdica constituye un eje integrador de promoción de salud en enfermedades vectoriales disminuyendo la deserción de madres/padres universitarios(AU)

Vector Diseases, promote the social responsibility of Higher Education institutions, sensitizing the student in training, to wards the promotion of health in attention to the most vulnerable populations. The design of bioeducational materials as an activity associated with the Playroom that allowsus to offer an integrative action in the face of student desertion from the university sector, who when facing maternity / paternity during their schooling run the risk of abandoning their careers. Neither the universities nor the State have infrastructure, policies, statutes that allow them to provide the necessary support. Therefore, when determining the desertion of university mothers / fathers from the Nursing career of the University of Guayaquil, it was proposed to verify the implementation of the Playroom as an integrating axis that, from the health promotion, addresses student desertion. A quantitative, experimental study was carried out, with a descriptive approach and a retrospective cohort. The sample consisted of 169 registered students. A frequency distribution of 24% graduates, 43% dropouts and 34% repeaters was observed; within the group of repeaters, the most frequent cause was child care in 31%. The percentage of willingness to use the playroom service was 90%, with 73% acceptance of the design of bioeducational materials for the prevention of vector diseases, resulting in dengue with an incidence of 87% as a theme. Similarly, 84% of the drop outs would resume their studies. In conclusion, a Playroom constitutes an integrating axis of health promotion in vector diseases, reducing the dropout rate of university mothers / fathers(AU)

RESUMO

Introducción: Los pacientes en estado crítico en su mayoría no están ubicados en tiempo, espacio y persona, e incluso algunos están inconscientes, lo cual los hace vulnerables a la actuación moral y ética de sus cuidadores. Objetivo: Describir el comportamiento bioético de enfermería en el cuidado del paciente en la unidad de cuidados intensivo del Hospital de Especialidades de Guayaquil Dr. Abel Gilbert Pontón, Ecuador. Métodos: Se trató de una investigación con enfoque cualitativo, de tipo etnografía clínica, para lo cual se seleccionaron cuatro enfermeras que trabajan en la unidad de cuidados intensivos de dicho hospital. La información fue recogida con entrevistas abiertas e interpretadas a través de un proceso de categorización. Resultados: Los resultados muestran las siguientes categorías: Primero, que el compromiso en la relación enfermera-paciente al momento de proporcionar atención en las unidades críticas refleja una cualidad moral de cuidado bioético y humanizante. Segundo, que las actitudes de empatía y aceptación del paciente como sujeto receptor del cuidado reconocen los valores bioéticos y humanizantes. Tercero, existe comprensión emocional, social y cultural de lo que significa estar en una situación de cuidados críticos según la perspectiva del paciente y su familia. Conclusiones: Se confirma que la bioética del cuidado de enfermería es una reflexión racional y crítica de los valores humanos implícitos en la percepción de satisfacción de las necesidades del paciente crítico, lo cual conlleva a proporcionar un cuidado con calidez, con disposición de comprenderlo y hacerlo sentir confortable, permitiendo establecer vínculos humanos entre paciente-enfermera (AU)

RESUMO

Extensive evidence exists regarding the efficacy and acceptability of medical abortion through 63 days since last menstrual period (LMP). In Mexico City's Secretariat of Health (SSDF) outpatient facilities, mifepristone-misoprostol medical abortion is the first-line approach for abortion care in this pregnancy range. Recent research demonstrates continued high rates of complete abortion through 70 days LMP. To expand access to legal abortion services in Mexico City (where abortion is legal through 12 weeks LMP), this study sought to assess the efficacy and acceptability of the standard outpatient approach through 70 days in two SSDF points of service. One thousand and one women seeking pregnancy termination were enrolled and given 200 mg mifepristone followed by 800 µg misoprostol 24-48 hours later. Women were asked to return to the clinic one week later for evaluation. The great majority of women (93.3%; 95% CI: 91.6-94.8) had complete abortions. Women with pregnancies ≤ 8 weeks LMP had significantly higher success rates than women in the 9th or 10th weeks (94.9% vs. 90.5%; p = 0.01). The difference in success rates between the 9th and 10th weeks was not significant (90.0% vs. 91.2%; p = 0.71). The majority of women found the side effects (82.9%) and the use of misoprostol (84.4%) to be very acceptable or acceptable. This study provides additional evidence supporting an extended outpatient medical abortion regimen through 10 weeks LMP.

RESUMO

We evaluated 23 tree tomato (Solanum betaceum) accessions from five cultivar groups and one wild relative (Solanum cajanumense) for 26 composition traits. For all traits we found highly significant differences (P<0.001) among the materials studied. The high diversity found within S. betaceum for composition traits was matched by a high diversity within each of the cultivar groups. We found that sucrose and citric acid were the most important soluble sugar and organic acid, respectively, in tree tomato. Fruit in the anthocyanin pigmented (purple) group had a carotenoid content similar to that in the yellow-orange cultivar groups. Total phenolic content was significantly correlated (r=0.8607) with antioxidant activity. Analyses of mineral content showed that tree tomato is a good source of K, Mg, and Cu. Multivariate principal components analysis (PCA) confirmed that an important diversity exists within each cultivar group. The results we have obtained indicate that the high diversity found within the tree tomato could be exploited for selection and breeding for developing the tree tomato as a commercial crop.
