Responses of soil microbiome to copper-based materials (nano and bulk) for agricultural applications: An indoor-mesocosm experiment.

The foreseen increasing application of copper-based nanomaterials (Cu-NMs), replacing or complementing existing Cu-agrochemicals, may negatively impact the soil microbiome. Thus, we studied the effects on soil microbiome function and composition of nano copper oxide (nCuO) or copper hydroxide NMs in a commercial (Kocide®3000) or a lab-synthetized formulation (nCu(OH)2) or bulk copper hydroxide (Cu(OH)2-B), at the commonly recommended Cu dose of 50 mg(Cu)kg-1 soil. Microbial responses were studied over 28 days in a designed indoor mesocosm. On day-28, in comparison to non-treated soil (CT), all Cu-treatments led to a reduction in dehydrogenase (95% to 68%), arylsulfatase (41% to 27%), and urease (40% to 20%) activity. There was a 32% increase in the utilization of carbon substrates in the nCuO-treatment and an increased abundance of viable bacteria in the nCu(OH)2-treatment (75% of heterotrophic and 69% of P-solubilizing bacteria). The relative abundance of Acidobacteria [Kocide®3000, nCuO, and Cu(OH)2-B treatments] and Flavobacteriia [nCu(OH)2-treatment] was negatively affected by Cu exposure. The abundance of Cu-tolerant bacteria increased in soils treated with Kocide®3000 (Clostridia) and nCu(OH)2 (Gemmatimonadetes). All Cu-treated soils exhibited a reduced abundance of denitrification-related genes (0.05% of nosZ gene). The DTPA-extractable pool of ionic Cu(II) varied among treatments: Cu(OH)2-B > Kocide®3000 âˆ¼ nCuO>nCu(OH)2, which may explain changes on the soil microbiome composition, at the genera and OTU levels. Thus, our study revealed that Cu-materials (nano and bulk) influence the soil microbiome with implications on its ecological role. It highlights the importance of assessing the impact of Cu-materials under dynamic and complex exposure scenarios and emphasizes the need for specific regulatory frameworks for NMs.

Effect of a Zinc Phosphate Shell on the Uptake and Translocation of Foliarly Applied ZnO Nanoparticles in Pepper Plants (Capsicum annuum).

Here, isotopically labeled 68ZnO NPs (ZnO NPs) and 68ZnO NPs with a thin 68Zn3(PO4)2 shell (ZnO_Ph NPs) were foliarly applied (40 µg Zn) to pepper plants (Capsicum annuum) to determine the effect of surface chemistry of ZnO NPs on the Zn uptake and systemic translocation to plant organs over 6 weeks. Despite similar dissolution of both Zn-based NPs after 3 weeks, the Zn3(PO4)2 shell on ZnO_Ph NPs (48 ± 12 nm; -18.1 ± 0.6 mV) enabled a leaf uptake of 2.31 ± 0.34 µg of Zn, which is 2.7 times higher than the 0.86 ± 0.18 µg of Zn observed for ZnO NPs (26 ± 8 nm; 14.6 ± 0.4 mV). Further, ZnO_Ph NPs led to higher Zn mobility and phloem loading, while Zn from ZnO NPs was stored in the epidermal tissues, possibly through cell wall immobilization as a storage strategy. These differences led to higher translocation of Zn from the ZnO_Ph NPs within all plant compartments. ZnO_Ph NPs were also more persistent as NPs in the exposed leaf and in the plant stem over time. As a result, the treatment of ZnO_Ph NPs induced significantly higher Zn transport to the fruit than ZnO NPs. As determined by spICP-TOFMS, Zn in the fruit was not in the NP form. These results suggest that the Zn3(PO4)2 shell on ZnO NPs can help promote the transport of Zn to pepper fruits when foliarly applied. This work provides insight into the role of Zn3(PO4)2 on the surface of ZnO NPs in foliar uptake and in planta biodistribution for improving Zn delivery to edible plant parts and ultimately improving the Zn content in food for human consumption.

Unique challenges to diagnosing sweet syndrome following induction chemotherapy for relapsed Acute Myeloid Leukemia (AML): A case and brief-review.

Background: Sweet Syndrome (SS) is a rare inflammatory skin condition characterized by the sudden appearance of tender, erythematous or violaceous papules, plaques, and nodules typically found on the face, neck, shoulder, upper extremities, and trunk. Often, SS is difficult to diagnose because of its various non-specific manifestations, including fever, arthralgia, myalgia and ocular involvement. In most cases described in literature, cutaneous and pulmonary symptoms of SS present in a concomitant manner. Several reported cases of pulmonary SS have shown that if left untreated, acute respiratory distress syndrome can ensue and progress to fatal respiratory failure. Case report: A 58-year-old female with acute myeloid leukemia (AML) secondary to chronic lymphocytic leukemia (CLL) presented with new nodular lesions, dyspnea, and fevers. Chest X-ray revealed pulmonary infiltrates. The patient developed new facial lesions and worsening hypoxic respiratory failure. Further infectious workup was negative. She was found to have SS with pulmonary involvement and initiated on high-dose intravenous (IV) steroids with marked clinical improvement. Conclusions: Major and minor criteria for the diagnosis of lung-associated SS should be carefully evaluated, especially when a biopsy is unavailable. The following case report describes the clinical course and outcomes from treatment for this patient.

Salt intake, blood pressure and cardiovascular disease mortality in England, 2003-2018.

OBJECTIVES: The aim of this study was to assess the changes in salt intake and concomitant changes in blood pressure (BP) and cardiovascular disease (CVD) mortality in England from 2003 to 2018. METHODS: National surveys and death registration data were used for the analysis of salt intake as measured by 24-h urinary sodium excretion (449-1069 participants per year), BP (2651-6738 participants per year) and CVD mortality. RESULTS: A decline in salt intake from 9.38 (SD 4.64) to 7.58 (3.41) g/d was observed between 2003 and 2014 ( P  < 0.01), followed by an increase to 8.39 (4.13) g/d in 2018 ( P  < 0.01). Similar trends in BP and CVD mortality were also observed between 2003 and 2018. SBP/DBP decreased from 125.3 (15.92)/74.48 (11.33) mmHg to 122.57 (14.92)/73.33 (10.75) mmHg between 2003 and 2014 ( P  < 0.01), followed by a plateau up to 2018 [122.04 (14.64)/73.84 (10.54) mmHg, P  > 0.05]. Likewise, a fall in stroke and ischaemic heart disease mortality rates was observed between 2003 and 2014, from 12.24 and 43.44 cases per 100 000, to 8.19 and 27.23 cases per 100 000 ( P  < 0.01), respectively, followed by a plateau afterwards ( P  > 0.05). CONCLUSION: The UK salt reduction programme was initially successful in reducing population salt intake by 19% (from 9.38 g/d in 2003 to 7.58 g/d in 2014). However, in recent years, the programme stalled and thus led to an interruption in the decline of salt intake. BP and CVD mortality reduction was also interrupted when salt reduction stalled. The changes in salt intake may have played an important role in the concomitant changes in BP and CVD mortality. Urgent action is needed to reinvigorate the UK's once world-leading salt reduction programme.

Granulated biomass fly ash coupled with fenton process for pulp and paper wastewater treatment.

The work describes the combination of granulated biomass fly ash (GBFA) with Fenton process to enhance the removal of adsorbable organic halides (AOX) from pulp bleaching wastewater. At optimal operating conditions, wastewater's chemical and biochemical oxygen demand (COD and BOD5, respectively) and colour were also quantified, and operating cost of treatment assessed. For the first time, raw pulp bleaching wastewater was used to granulate BFA, instead of water, reducing the water footprint of the treatment. Five wastewater treatment setups were studied: (i) conventional Fenton process; (ii) GBFA application; (iii) simultaneous application of GBFA and Fenton process; (iv) sequential treatment by GBFA followed by Fenton process; (v) sequential treatment by Fenton process followed by GBFA. The latter yielded the highest AOX removal (60-70%), whilst COD was also reduced (≈15%) and wastewater biodegradability (BOD5/COD) was enhanced from 0.075 to a maximum of 0.134. Another positive feature of the proposed solution was that GBFA were successfully recovered and reused without regeneration, yielding similar AOX removal compared with fresh GBFA. The operating cost of removing 1 g of AOX from the pulp bleaching wastewater by the optimal treatment setup (60-70% removal of AOX) was 14-26% lower than the operating cost of conducting Fenton process alone (50% removal of AOX).

Efficacy of the Therapeutic Game "Trisquel" in the Treatment of Patients With Substance-Related Disorders Randomized Clinical Study.

Substance-related disorders (SRD) have been consistently associated with alterations both in cognitive and executive functions, which affect to patients' quality of life. The main objective of this work was to test the beneficial cognitive effects on patients with SRD after the implementation of "Trisquel," an intervention program in board game format. To check the effectiveness of Trisquel program, a group of people diagnosed with SRD was randomly assigned either to the experimental group or to the control group. The experimental group performed Trisquel structured sessions twice a week during 3 months, while the control group performed routinely conventional therapeutic activities with the same frequency and duration. Neuropsychological tests were done to both groups before and after the intervention. After the 3 months of intervention the experimental group showed the following statistically significant improvements for WAIS-III subtests: number key, symbol search, arithmetic, direct digits, inverse digits, total digits, letters-numbers in the processing speed index and in the working memory index. Regarding STROOP tests, statistically significant progress was observed in the phonetic fluency letter P, phonetic fluency letter M, phonetic fluency letter R subtests, word-reading and word-color subtests. The control group only obtained improvements for WAIS-III subtests of arithmetic, letters-numbers and in the working memory index. The results of this study confirm that "Trisquel" is an effective intervention program for people diagnosed with SRD, getting improvements in processing speed (psychomotor and reading), attentional subprocesses (focused and sustained) and executive functions (updating and inhibition).

Examining Empowerment Interventions With Families and Preschool Children: Systematic Review of Randomized Controlled Trials.

Empowerment is a core construct in health behavior and an emerging trend in pediatrics. Although it has been suggested as an approach that may promote the person's participation in health care decisions and positive outcomes, little is known about the nature and effectiveness of interventions to support empowerment in families and preschool-age children. The aim of this review is to identify, appraise, and synthesize the evidence on health interventions explicitly using empowerment as an orienting concept with families and their preschool-age children. We identified randomized controlled trials (RCTs) through systematic searches of eight databases for articles published between 1986 and January 2019 and included RCTs that addressed empowerment as a health intervention approach or outcome and that studied families with 3- to 5-year-old children. The application of empowerment theory, the family and child involvement, and the use of behavior change techniques (BCTs) were assessed through appropriate frameworks. Ten interventions were identified, and 50% of them showed positive outcomes. Most studies claimed a theoretical base. However, the studies provided limited details on theory application in intervention planning, implementation, and evaluation, and the children's involvement in the interventions was generally scarce. The most commonly applied BCT was "instruction in how to perform the behavior." We identified 16 potentially effective BCTs. The evidence was not sufficiently robust to determine the effectiveness of empowerment interventions with families and preschool-age children. Additional high-quality studies are needed to produce clearer conclusions. Our results are useful for the design and evaluation of future interventions.

Psicanálise na assistência social em Fortaleza-CE: um estudo sobre as medidas socioeducativas / Psychoanalysis in social assistance in Fortaleza - Ceará: a study about socio-educational measures / El psicoanálisis en la asistencia social en Fortaleza-CE: un estudio sobre las medidas socioeducativas

Este artigo pretende apresentar alguns encontros e diálogos da psicanálise com o Sistema Único de Assistência Social (Suas), amparados na escuta e na pesquisa sobre a prática profissional dos psicanalistas no acompanhamento de jovens em cumprimento de medidas socioeducativas. O Suas representa um importante campo de atuação e de contribuições tanto na assistência direta aos usuários quanto na elaboração de novas tecnologias psicossociais. Cabe destacar a presença da psicanálise como linha teórica norteadora desse debate, que se organiza em torno dos encontros entre psicanálise, assistência social e medidas socioeducativas, no contexto da realidade do adolescente em conflito com a lei na cidade de Fortaleza. Concluímos que, embora as instituições apresentadas não sejam a princípio parte do campo tradicional da psicanálise, o psicanalista pode contribuir para o trabalho com esses jovens com sua escuta singular, seu posicionamento ético e seu rigor teórico. Sua atuação pode colaborar, assim, para que o cidadão de direitos e o sujeito da psicanálise sejam acolhidos e contemplados nas políticas públicas de Assistência Social.

This essay seeks to present possible encounters and dialogues between psychoanalysis and the Brazilian Unified System for Social Assistance (SUAS), based on the practice of listening and on the research concerning psychoanalysts' professional procedures when working with adolescents following socio-educative measures. The SUAS is an important field of action and contribution for psychology professionals, both in the direct assistance to the users and in the development of new psychosocial technologies. Psychoanalysis is the guiding theoretical line for this discussion, which organizes itself based on the association of psychoanalysis, the work of social assistance, and socio-educational measures, in the context of youngsters in conflict with the law in the municipality of Fortaleza, capital of Ceará. We conclude that, even though the discussed institutions are not traditionally linked to the field of psychoanalysis, psychoanalysts may contribute to the work with these adolescents with their individual attention, ethical positioning, and theoretical rigor. These professionals may, thus, be an important asset in the appropriate reception and support to the citizens and psychoanalytical subjects of Social Assistance public policies.

Nutritional Quality of Plant-Based Meat Products Available in the UK: A Cross-Sectional Survey.

Plant-based meat (PBM) has been gaining popularity due to increasing concerns over health, animal welfare, and environmental issues linked to animal foods. This study aimed to compare the nutrient profile of PBM with equivalent meat products. We conducted a cross-sectional survey of 207 PBM and 226 meat products available from 14 retailers in the UK. We extracted data on energy density, total and saturated fat, protein, fiber, and salt per 100 g from product packaging and calculated the nutrient profile of each product. Compared to meat, PBM had significantly lower energy density, total fat, saturated fat, protein, and significantly higher fiber. Salt content was significantly higher in five out of six PBM categories. Based on the UK's Nutrient Profiling Model, 14% of PBM and 40% of meat products were classified as "less healthy" (p < 0.001). When considering the UK's front-of-pack labelling criteria 20% of the PBM and 46% of meat products were considered high in either total fat, saturated fat, or salt (p < 0.001). Nearly three quarters of PBM products did not meet the current UK salt targets. PBM products have a better nutrient profile compared to meat equivalents. However, more progress is needed to reduce salt in these products.

Biomass ash formulations as sustainable improvers for mining soil health recovery: Linking soil properties and ecotoxicity.

There is a growing need to recover degraded soils to restore their essential ecosystem services and limit damages of anthropic activities onto these systems. Safe and sustainable solutions for long-term recovery must be designed, ideally by recycling existing resources. Using ash from combustion of residual forest biomass at the pulp and paper industry is an interesting and sustainable strategy to recover mining soils. However, formulations must be found to limit the potential toxicity associated with soluble salts and chloride that ash contains. Here, we assessed the effectiveness of three field ash-based amendments for the recovery of three highly acidic soils from Portuguese abandoned mines. Three amendments were tested: an un-stabilized mixture of ash and biological sludge, granulated ash, and granulated ash mixed with composted sludge. One year after application in open field plots (in the scope of LIFE No_Waste project), soil health restoration was evaluated through (i) soil physico-chemical characterization and (ii) soil habitat functions though standardized ecotoxicological tests. This study highlights that stabilized materials provided nutrients, organic matter and alkalinity that corrected soil pH and decreased metal bioavailability, while controlling the release of soluble salts and chloride from ash. This soil improvement correlated with improved soil model organisms' reproduction and survival. For similar amendment, the native soil properties studied (as soil native electrical conductivity) affected the level of organism response. This work provides evidence that ash stabilization, formulation and supplementation with organic matter could be sustainable strategies to restore highly degraded mining soils and to recover their ecological functions. It further highlights the importance of analyzing combined effects on soil physico-chemical properties and ecological function recovery to assess restoration strategy efficiencies in complex multi-stressor environments.

Allergen extraction: Factors influencing immunogenicity and sensitivity of immunoassays.

Food allergy prevalence is increasing worldwide, therefore there is a high demand for reliable tests to correctly diagnose this disease. Knowledge of proteins allergenicity and how they react both in the body and in diagnostic tests is necessary to adequately assess the potential immunogenicity of both natural foods and those produced through biotechnological processes. Thus, our aim was to analyze the factors that influence the protein extraction of foods in terms of, immunogenicity and immunoassays sensitivity. Peanut proteins were extracted using four distinct extraction buffers with different pH values (physiological saline, tris buffer, borate buffer with and without ß-mercaptoethanol), the protein concentration was determined by the Lowry method and polyacrylamide electrophoresis (SDS-PAGE) was used to compare the protein profile of each extract. The immunogenicity of each extract was verified by sensitizing two mouse strains (Balb/c and C57Bl/6) with a solution containing 100 µg of the extracted proteins and was determined by ELISA. Results show that extraction with the distinct buffers resulted in protein solutions with different yields and profiles. The immunogenicity of the different extracts also demonstrated distinct patterns that varied depending on the extraction methods, mouse strain and in vitro test. Immunoreactivity varied in accordance with the protein extract used to coat the microtitration plates. In conclusion, the protein profile in the extracts is critically influenced by the salt composition and pH of the extraction buffers, this in turn influences both in vivo immunogenicity and in vitro immunoreactivity.

Measuring Empowerment Counselling in Routine Primary Health Care: Psychometric Properties of a Portuguese Adaptation of the Empowering Speech Practices Scale.

PURPOSE: Empowerment is a widely accepted approach to health promotion in which primary care nurses play an important role. Despite its clinical importance, empirical knowledge is low, mainly due to the lack of instruments to measure this construct. The Empowering Speech Practices Scale (ESPS) is a Finnish measure used to assess the empowerment process in counselling sessions. We designed this study to assess the psychometric properties of a Portuguese adaptation of the ESPS for families of 5-year-old children and nurses in well-child visits. DESIGN AND METHODS: We used a cross-sectional survey design. The ESPS was translated and adapted to the context of children and family health promotion. We administered a sociodemographic questionnaire and the Portuguese ESPS to a sample of 82 families attending a 5-year-old well-child visit and 25 primary care nurses in Portugal. We evaluated the Portuguese ESPS for construct validity and internal consistency. RESULTS: Exploratory factor analysis supported a 44-item scale, two-component model, which is similar to the original version, explaining 73.79% of the total variance. Each subscale presented excellent internal consistency and distinguished consultations conducted by nurses with academic training in empowerment patient education. CONCLUSIONS AND IMPLICATIONS: The Portuguese ESPS is a valid and reliable instrument for assessing empowerment in health counselling with families in well-child visits. It looks at the process from two perspectives: the nurses' and the families' perspectives. It can be useful to evaluate quality of care, to identify areas of improvement, and to delve deeper into relationships between empowerment and health outcomes.

Critical Review: Role of Inorganic Nanoparticle Properties on Their Foliar Uptake and in Planta Translocation.

There is increasing pressure on global agricultural systems due to higher food demand, climate change, and environmental concerns. The design of nanostructures is proposed as one of the economically viable technological solutions that can make agrochemical use (fertilizers and pesticides) more efficient through reduced runoff, increased foliar uptake and bioavailability, and decreased environmental impacts. However, gaps in knowledge about the transport of nanoparticles across the leaf surface and their behavior in planta limit the rational design of nanoparticles for foliar delivery with controlled fate and limited risk. Here, the current literature on nano-objects deposited on leaves is reviewed. The different possible foliar routes of uptake (stomata, cuticle, trichomes, hydathodes, necrotic spots) are discussed, along with the paths of translocation, via the phloem, from the leaf to the end sinks (mature and developing tissues, roots, rhizosphere). This review details the interplays between morphological constraints, environmental stimuli, and physical-chemical properties of nanoparticles influencing their fate, transformation, and transport after foliar deposition. A metadata analysis from the existing literature highlighted that plant used for testing nanoparticle fate are most often dicotyledon plants (75%), while monocotyledons (as cereals) are less considered. Correlations on parameters calculated from the literature indicated that nanoparticle dose, size, zeta potential, and affinity to organic phases correlated with leaf-to-sink translocation, demonstrating that targeting nanoparticles to specific plant compartments by design should be achievable. Correlations also showed that time and plant growth seemed to be drivers for in planta mobility, parameters that are largely overlooked in the literature. This review thus highlights the material design opportunities and the knowledge gaps for targeted, stimuli driven deliveries of safe nanomaterials for agriculture.

Investigation of pore water and soil extraction tests for characterizing the fate of poorly soluble metal-oxide nanoparticles.

Here we compared the efficiency of Cu extraction (dissolved + particulate) from two soils dosed with CuO nanoparticles (NPs) at 50 or 250 mg kg-1 by pore water collection, and single- and multi-step soil extraction tests. Pore water collection recovered low levels of Cu (<0.18%, regardless of soil type or Cu dose). Single soil extraction by either CaCl2 or DI water led to higher Cu recovery than pore water collection, but still <3% of total dose. These methods were useful for assessing the labile Cu ions pool. This fraction is controlled by Cu2+ dissolved from CuO NPs and it varies with time and soil type. Particulate Cu was poorly retrieved (<0.7%) by pore water extraction and by single-step soil extraction using CaCl2 solution or water. Multi-step extraction including dispersing and metal-chelating agents allowed for simultaneous characterization of dissolved Cu (total ionic Cu2+, 24-49% of dosed Cu), extractable CuO NPs (reversibly attached, 15-26% of dosed Cu), and non-extractable CuO NPs (irreversibly attached, 36-50% of dosed Cu), and it could describe the aging of NPs along 30 d. This method extracted a significantly higher concentration of Cu than pore water collection and was less sensitive to method parameters (e.g. filtration). This multi-step method can reduce pore water extraction-related factors that may confound the interpretation of environmental exposure data in NPs studies, and describe upper limits of both exchangeable Cu2+ and dispersible CuO NPs in soil that can potentially become bioavailable to plants and organisms and thus provide a sounder basis for risks evaluations.

Two sides of the same well-child visit: Analysis of nurses' and families' perspectives on empowerment in health counselling.

AIMS: To explore the degree of empowering health counselling in well-child visits, considering nurse and family perspectives and to examine its associated factors. BACKGROUND: Empowerment has gained high priority in the world health strategy, being claimed for its benefits for people's health and well-being. DESIGN: The design includes an exploratory cross-sectional, correlational study. METHODS: We collected data between January 2018-October 2019 from a convenience sample of 82 families attending a 5-year-old well-child visit and 25 nurses at Portuguese health centres. Families and nurses assessed the same counselling session using parallel statements of the Portuguese Empowering Speech Practice Scale, grouped in two subscales (nurses' action and families' action). Questionnaires also included the Parent's Longitudinal Continuity in Primary Care scale, the Family Nutrition and Physical Activity tool and anthropometric and sociodemographic questions. We employed descriptive statistics, paired-samples t-test, analysis of variance and regression analysis. RESULTS: Both nurses and families reported that empowerment had been practiced in high degree. The most practiced elements were those from nurses' action subscale (e.g. constructing a positive atmosphere) and the least practiced were from families' action (e.g. disclosure). A discrepancy between nurses' and families' ratings were found for individualized information and advice, disclosure and asking questions, with families reporting higher scores. Nurses' formal training in empowerment and obesity was associated with higher scores on the nurses' action subscale. The families' limited experience with a regular health centre and nurse and families having children with overweight were both associated with lower scores on the two subscales. CONCLUSIONS: Although the positive experience by nurses and families is an important finding, the reasons for the differences in perceptions of empowerment require further research. IMPACT: The Portuguese Empowering Speech Practice Scale can be a useful tool to evaluate services, both from professionals' and families' perspectives and to identify areas of improvement.

Nutrition Profile of Products with Cartoon Animations on the Packaging: A UK Cross-Sectional Survey of Foods and Drinks.

BACKGROUND: Marketing, including the use of cartoon animations on packaging, has been shown to influence the food children choose to eat. This paper aims to determine the nutritional quality of UK food and drink products featuring child-friendly characters on pack. METHODS: A comprehensive cross-sectional survey of food and drink with packaging appealing to children available in the UK. Products were classified high in fat, salt and/or sugar (HFSS) according to the UK nutrient profiling model and guidance for front of pack nutrition labelling. Logistic regression was used to determine whether there was a significant relationship between nutritional quality of products, and animation type. RESULTS: Over half (51%) of 532 products with animations on packaging were classified as HFSS. Food products featuring unlicensed characters were significantly more likely to be deemed HFSS than those with licensed characters, according to both the nutrient profiling model (odds ratio (OR) 2.1, 95% CI: 1.3 to 3.4) and front of pack nutrition labelling system (OR 2.3, 95% confidence interval CI: 1.4 to 3.7). CONCLUSIONS: The use of cartoon characters on HFSS products is widespread. Policies to restrict the use of such marketing tactics should be considered to prevent children being targeted with unhealthy foods and drinks.

Use of wastes from the pulp and paper industry for the remediation of soils degraded by mining activities: Chemical, biochemical and ecotoxicological effects.

Fly ash (FA) from biomass combustion and biological sludge (S), both wastes from the pulp and paper industry, were granulated in different proportions (90% FA+10% S, and 70% FA+30% S w/w, dry weight basis, dw) and used to recover the functionality of soils affected by mining activities (Aljustrel, Iberian Pyrite Belt), with and without the application of municipal solid waste compost (MSWC). Application doses of both mixtures were 2.5, 5.0 and 10% (w/w, dw). These materials corrected soil acidity to circumneutral values and increased extractable P and K concentrations. A significant increase in soil organic matter (from 0.6 to 0.8-1.5% w/w, dw) and N content (from 0.04 to 0.09-0.12% w/w, dw) was also observed, but only when MSWC was applied. The soil was already heavily contaminated with Cu, Pb and Zn and the application of amendments did not increase their pseudo-total concentrations. The CaCl2 extractable fractions of both Cu and Zn decreased to very low values. The improvement in soil quality, compared to fertilizer only treatment, was further evidenced by the increase in some soil enzymatic activities (dehydrogenase, ß-glucosidase and cellulase), with a better response for the granules with the higher proportion of biological sludge, as well as by the decrease in the soil-water extract toxicity towards different organisms (Daphnia magna, Thamnocephalus platyurus, and Pseudokirchneriella subcapitata). Agrostis tenuis germinated and grew during the first month only in the amended pots, but, after that, a considerable phytotoxic effect was evident. This was mainly attributed to salt stress or to some specific ionic toxicity. In conclusion, to establish a long-term plant cover in mining soils amended with biomass ash-based materials, the selection of plants with higher resistance to salinity and/or the stabilization of the amendments, to reduce their soluble salt content, is recommended.

Global Impact of Peripheral Obstructive Arterial Disease in Portugal: An Eight Year Study.

INTRODUCTION: Peripheral arterial disease has an important impact on morbidity/mortality. The objective of this study was to quantify the impact of this disease in Portugal during the last eight years, expressed by the volume of admissions, treatment strategies and associated morbidity and mortality. MATERIAL AND METHODS: We collected data from the Diagnosis Related Group national database on primary diagnosis, procedures codes, demographic variables, a number of risk factors, and mortality of all cases admitted from 2009 to 2016 with a primary diagnosis of peripheral arterial disease coded according to the 9th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-9). RESULTS: In this study, peripheral arterial disease led to 27 684 hospitalisations, which corresponded to 26.7% of all admissions for vascular disease in this period. Approximately 49.9% of patients were admitted to the emergency department. The volume of procedures in patients with claudication decreased over the eight years, unlike patients with critical ischaemia, in which the number of procedures increased. DISCUSSION: Age and the presence of cardiovascular risk factors have been associated with the severity of disease, as observed in our series. Overall hospital mortality varied, being significantly higher in patients with more advanced severity of the disease. CONCLUSION: Peripheral arterial disease represents an important burden in the overall volume of admissions in Portuguese public hospitals. A large number of patients was admitted in the context of emergency.

Introdução: A doença arterial obstrutiva periférica tem um importante impacto a nível de morbi/mortalidade. O objetivo deste trabalho é quantificar o impacto desta doença em Portugal, ao longo dos últimos oito anos, expresso pelo volume de internamento, tratamento e pela morbi-mortalidade respetiva. Material e Métodos: Foram analisados os registos de internamento no Serviço Nacional de Saúde entre 2009 e 2016 da base de dados dos grupos de diagnósticos homogéneos utilizando os códigos 9th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-9) de diagnóstico e procedimentos. Verificámos o número de casos em cada ano por estadio de doença, dados demográficos, fatores de risco, tratamento e morbi-mortalidade. Resultados: No período de estudo a doença arterial periférica conduziu a 27 684 internamentos o que correspondeu a cerca de 26,7 % do total de internamentos por patologia vascular neste período. Cerca de 49,9 % dos doentes foram admitidos em contexto de urgência. Os procedimentos em doentes claudicantes diminuíram ao longo dos oito anos ao contrário dos doentes com isquémia crítica em que os procedimentos aumentaram. Discussão: A idade e a presença de fatores de risco cardiovasculares têm sido associadas à gravidade da doença, tal como na nossa série. A mortalidade hospitalar global varia, sendo mais significativa nos doentes com doença mais avançada. Conclusão: A doença arterial periférica é uma patologia com importante representação no internamento dos hospitais do Serviço Nacional de Saúde. Há ainda um importante volume de doentes admitidos no contexto de urgência o que sugere eventual falta de reconhecimento/referenciação atempada por parte dos cuidados saúde primários, devendo mais esforços ser realizados no sentido de aumentar a interação entre os cuidados de saúde primários e os hospitais terciários.

Effect of Soil Organic Matter, Soil pH, and Moisture Content on Solubility and Dissolution Rate of CuO NPs in Soil.

The objectives of this research were to quantify the impact of organic matter content, soil pH and moisture content on the dissolution rate and solubility of copper oxide nanoparticles (CuO NPs) in soil, and to develop an empirical model to predict the dissolution kinetics of CuO NPs in soil. CuO NPs were dosed into standard LUFA soils with various moisture content, pH and organic carbon content. Chemical extractions were applied to measure the CuO NP dissolution kinetics. Doubling the reactive organic carbon content in LUFA 2.1 soil increased the solubility of CuO NP 2.7-fold but did not change the dissolution rate constant. Increasing the soil pH from 5.9 to 6.8 in LUFA 2.2 soil decreased the dissolution rate constant from 0.56 mol1/3·kg1/3·s-1 to 0.17 mol1/3·kg1/3·s-1 without changing the solubility of CuO NP in soil. For six soils, the solubility of CuO NP correlated well with soil organic matter content ( R2 = 0.89) independent of soil pH. In contrast, the dissolution rate constant correlated with pH for pH < 6.3 ( R2 = 0.89), independent of soil organic matter content. These relationships predicted the solubility and dissolution rate constants of CuO NP in two test soils (pH 5.0 and pH 7.6). Moisture content showed negligible impact on the dissolution kinetics of CuO NPs. Our study suggests that soil pH and organic matter content affect the dissolution behavior of CuO NP in soil in a predictable manner.

Epiretinal Proliferations Associated with Lamellar Macular Holes: Clinical and Surgical Implications.

OBJECTIVES: To describe the prevalence of lamellar hole-associated epiretinal proliferation (LHEP) and to correlate this finding with lamellar macular hole (LMH) morphology and prognosis after a surgical or conservative approach. METHODS: This is a retrospective multicenter case series comprising consecutive LMH patients followed for ≥6 months. Serial spectral-domain optical coherence tomographies were evaluated for the presence of epiretinal membrane (ERM) and LHEP, diameter of the LMH aperture, base, and floor thickness. Pars plana vitrectomy with ERM and internal limiting membrane peeling was performed in the surgical cases. RESULTS: A total of 62 eyes from 57 consecutive patients were included. Mean follow-up time was 27.1 ± 19.8 months. LHEP was observed in 33 (53.2%) eyes. Patients with LMH and LHEP presented a larger external diameter (p = 0.001) and thinner floors (p = 0.018). Twenty-seven (81.8%) of the patients with LMH and LHEP presented a degenerative intraretinal cavitation, compared to 23.3% in the non-LHEP group (p = 0.001). No differences were observed in visual performance or closure rate between the 2 groups after surgery or in the subset of patients followed conservatively. CONCLUSIONS: LHEP was correlated with the anatomical conformation of the LMH, yielding thinner floors and larger external diameters. However, it did not correlate with the anatomical or functional results, both in the patients who underwent surgery and in those managed conservatively.
