Obtaining accurate population estimates with reduced workload and lower fish mortality in multi-mesh gillnet sampling of a large pre-alpine lake.

The EU Water Framework Directive requires monitoring of the ecological status of lakes, with fish as a relevant class of biotic quality indicator, but monitoring fish populations in large lakes is demanding. This study evaluated use in Lake Constance of a novel multi-mesh gillnet modified to reduce catch numbers. In direct comparison with conventional European Committee for Standardization (CEN) nets we achieved 48% reduction in fish mortality with 38% less labour for tasks directly influenced by fish catch numbers, while maintaining comparable species composition and catch per unit effort. Comparison of mesh sizes indicated no significant reduction in species detection in area-reduced panels of the small mesh sizes, while total observed species richness was greater when using the modified nets. Differences in benthic species communities among depth strata were common, while those of pelagic zones were more homogeneous and did not differ significantly with depth. Catches of different net types from the same depth stratum did not exhibit significant differences. The dominance structure of the most common species, relevant to lake assessment, was similar in catches of both net types, suggesting overall superiority of the modified nets in Lake Constance. Sampling conducted according to standard European CEN protocol, while deploying 60% fewer nets, yielded sufficiently precise abundance estimates for monitoring shallow areas of the benthic zone. A 50% difference in the abundance of dominant species was detected among sampling events with a certainty of 95%. The sample did not provide comparable accuracy in deep benthic strata or the pelagic zone, but was adequate to record complete inventories of species present. Based on this trial data, a new stratified sampling design is proposed for monitoring large lake fish communities for ecological assessment. Depth-dependent fish communities were used to calculate the required number of nets, which resulted in a 69% reduction for the entire lake compared to the CEN calculation method. Using the modified nets increases the feasibility of performing WFD surveys, by reducing effort and cost, while the simultaneous halving of fish mortality minimises the negative impact of fish surveys.

T-large Granular Lymphocytic Leukemia: A Rare Diagnosis in a Young Woman With Fever, Necrotic Skin Lesions and Cytopenias.

T-large granular lymphocytic leukemia (T-LGLL) is a rare lymphoproliferative disorder. The diagnosis is established by identifying an abnormally high number of clonal granular T lymphocytes in the peripheral blood and eventually in the bone marrow, in cases with medullary infiltration. The majority of patients present with symptoms related to neutropenia and this condition may be associated with autoimmune diseases in up to a third of cases. The authors describe the case of a 26-year-old patient admitted with subacute high fever and bullous dermatitis with necrotic lesions with central bullae. Analytically, she presented anemia and leukopenia with severe neutropenia of 200 cells/L. Skin lesions were compatible with ecthyma and the skin biopsy revealed aspects compatible with leukocytoclastic vasculitis. The myelogram and bone biopsy revealed hypoplasia of the myeloid line and a pathological T population of CD8+, TIA-1+ and granzyme B+, which were associated with compatible flow cytometry (CD3+, T-cell receptor (TCR) Alpha-Beta+, CD5+, CD2+, with loss of CD7 antigen expression) established the diagnosis of T-LGLL. The patient had a favorable evolution, with cytopenias almost returning to normal after two months. She began follow-up at a Hematology Reference Center, remaining asymptomatic without specific treatment considering the indolent course of the disease.

[Hansen's Disease: An Unusual Manifestation of an Ancient Disease]. / Doença de Hansen: Apresentação Incomum de uma Doença Antiga.

Hansen's disease, commonly known as leprosy, is an infectious disease caused by Mycobacterium leprae. Being rare in developed countries, it is an increasingly common imported disease due to the migratory flow from countries where it is endemic. We present the case of a 21-year-old man who went to the emergency department with complaints of additive polyarthralgia involving large joints, papules, and erythematous plaques on the limbs with bullae and central necrosis and fever with chills for one week. Skin biopsy was performed revealing neutrophilic infiltrate with perineural granulomas. The bacilloscopy detected acid-alcohol resistant bacilli. The diagnosis of multibacillary HD with type 2 lepromatous reaction (erythema nodosum leprosum - ENL) was established, showing clinical improvement under corticosteroid therapy. ENL usually presents with painful lesions, being an atypical presentation of leprosy, especially in the presence of bullae and necrosis, making diagnosis difficult and challenging. Social stigma is often present making it difficult to accept the disease as well as adherence to treatment.

A doença de Hansen, vulgarmente conhecida como lepra, é uma doença infecciosa causada por Mycobacterium leprae. Sendo rara nos países desenvolvidos, configura uma doença de importação cada vez mais frequente considerando o fluxo migratório de países onde é endémica. Apresentamos o caso de um homem de 21 anos que recorreu ao serviço de urgência por poliartralgias de caráter aditivo envolvendo grandes articulações, pápulas e placas eritematosas nos membros com bolhas e necrose central e febre com calafrio com uma semana de evolução. Foi realizada biópsia cutânea que revelou infiltrado neutrofílico com granulomas de distribuição perineural e baciloscopia com deteção de bacilos ácido-álcool resistentes. Foi estabelecido o diagnóstico de DH multibacilar com reação lepromatosa tipo 2 (eritema nodoso leproso), apresentando melhoria clínica sob corticoterapia. O eritema nodoso leproso cursa habitualmente com lesões dolorosas, configurando uma apresentação atípica de lepra, sobretudo na presença de bolhas e necrose, tornando este diagnóstico altamente desafiante. O estigma social é frequentemente limitativo na aceitação da doença e adesão ao tratamento.

Roadmap on optical sensors.

Optical sensors and sensing technologies are playing a more and more important role in our modern world. From micro-probes to large devices used in such diverse areas like medical diagnosis, defence, monitoring of industrial and environmental conditions, optics can be used in a variety of ways to achieve compact, low cost, stand-off sensing with extreme sensitivity and selectivity. Actually, the challenges to the design and functioning of an optical sensor for a particular application requires intimate knowledge of the optical, material, and environmental properties that can affect its performance. This roadmap on optical sensors addresses different technologies and application areas. It is constituted by twelve contributions authored by world-leading experts, providing insight into the current state-of-the-art and the challenges their respective fields face. Two articles address the area of optical fibre sensors, encompassing both conventional and specialty optical fibres. Several other articles are dedicated to laser-based sensors, micro- and nano-engineered sensors, whispering-gallery mode and plasmonic sensors. The use of optical sensors in chemical, biological and biomedical areas is discussed in some other papers. Different approaches required to satisfy applications at visible, infrared and THz spectral regions are also discussed.

When Cognitive Reflection Leads to Less Overall but More Systematic Judgment Bias: The Case of the Base Rates Fallacy.

Although widely used in the judgment under uncertainty literature, the so-called Lawyer-Engineer problem does not have a Bayesian solution because the base rates typically oppose qualitative stereotypical information, which has an undefined diagnostic value. We propose an experimental paradigm that elicits participants' subjective estimates of the diagnosticity of stereotypical information and allows us to investigate the degree to which participants are able to integrate both sources of information (base rates and stereotypical descriptions) according to the Bayesian rule. This paradigm was used to test the hypothesis that the responses (probability estimates) to the Lawyer-Engineer problem from more rational individuals deviate from normative Bayesian solutions in a way that shows smaller but more systematic bias. The results further suggest that the estimates of less rational participants are noisier (less reliable) but may be more accurate when aggregated across several problems.

Layered double hydroxides for corrosion-related applications-Main developments from 20 years of research at CICECO.

This work describes the main advances carried out in the field of corrosion protection using layered double hydroxides (LDH), both as additive/pigment-based systems in organic coatings and as conversion films/pre-treatments. In the context of the research topic "Celebrating 20 years of CICECO", the main works reported herein are based on SECOP's group (CICECO) main advances over the years. More specifically, this review describes structure and properties of LDH, delving into the corrosion field with description of pioneering works, use of LDH as additives to organic coatings, conversion layers, application in reinforced concrete and corrosion detection, and environmental impact of these materials. Moreover, the use of computational tools for the design of LDH materials and understanding of ion-exchange reactions is also presented. The review ends with a critical analysis of the field and future perspectives on the use of LDH for corrosion protection. From the work carried out LDH seem very tenable, versatile, and advantageous for corrosion protection applications, although several obstacles will have to be overcome before their use become commonplace.

When Type 2 Processing Misfires: The Indiscriminate Use of Statistical Thinking about Reasoning Problems.

Research on dual-process theories of judgment makes abundant use of reasoning problems that present a conflict between Type 1 intuitive responses and Type 2 rule-based responses. However, in many of these reasoning tasks, there is no way to discriminate between the adequate and inadequate use of rules based on logical or probabilistic principles. To experimentally discriminate between the two, we developed a new set of problems: rule-inadequate versions of standard base-rate problems (where base rates are made irrelevant). Across four experiments, we observed conflict sensitivity (measured in terms of response latencies and response confidence) in responses to standard base-rate problems but also in responses to rule-inadequate versions of these problems. This failure to discriminate between real and merely apparent (or spurious) conflict suggests that participants often misuse statistical information and draw conclusions based on irrelevant base rates. We conclude that inferring the sound use of statistical rules from normatively correct responses to standard conflict problems may be unwarranted when this kind of reasoning bias is not controlled for.

A Refractory Case of Amiodarone Thyrotoxicosis.

Amiodarone is frequently used to control cardiac arrhythmias, like atrial fibrillation. Despite its benefits, it has many adverse effects, particularly on the thyroid gland. We describe the case of a patient treated with amiodarone for paroxysmal atrial fibrillation, admitted to the emergency room with atrial fibrillation with a rapid ventricular response. Type II thyrotoxicosis was identified as the cause of the refractory arrhythmia. Since its refractoriness to both pharmacological and electrical therapy, there was a need to proceed with plasmapheresis and total thyroidectomy for hormonal and cardiac rhythm control. Therefore, it is essential to monitor the toxicity of amiodarone, a drug that can have both beneficial and devastating effects.

Bem-Estar, Mal-Estar e Gerenciamento de Qualidade de Vida no Trabalho / Well-being, Malaise and Quality of Work Life Management / Bienestar, Malestar y Gestión de la Calidad de Vida en el Trabajo

The issue of quality of working life (QWL) has assumed social and corporate relevance due to the worsening of harmful indicators for the health and safety of workers and the scope of the organizational mission. The research aimed to highlight the structuring representations of well-being and malaise at work by servants of a public organization seeking to contribute to the sustainable management of QWL. A total of 1,110 civil ser-vants of an executive branch of the Federal District, in Brazil, participated in the survey. Data were collected based on two open questions from the qualitative part of the Quality of Working Life Assessment Inventory (QWL-AI) and were analyzed using the Interface de R pour les Analyses Multidimensionnelles de Textes et de Ques-tionnaires (IRaMuTeQ) application. The results pointed to three discourse structuring thematic nuclei for work well-being (having a good relationship with colleagues, doing a job you like, and feeling useful to society) and malaise at work (work overload, lack of recognition, time pressure, and rework). Therefore, sustainable man-agement of QWL must be anchored in people management practices that foster professional development, the alignment between tasks, roles, and organizational mission, highlighting the social contributions, the recognition of the worker by their superiors, peers, and society, and the review of work organization, focusing on the reassessment of work processes, distribution of demands, and ways of setting and demanding goals

A questão da Qualidade de Vida no Trabalho (QVT) tem relevância social e corporativa em face do agravamento de indicadores nocivos para a saúde e segurança dos trabalhadores e o alcance da missão organizacional. A pesquisa objetivou evidenciar as representações estruturantes das vivências de bem-estar e mal-estar no trabalho por servidores de uma organização pública visando contribuir para o gerenciamento sustentável de QVT. Participaram da pesquisa 1.110 servidores de um órgão do poder executivo do Distrito Federal, no Brasil. Os dados foram coletados com base em duas questões abertas da parte qualitativa do Inventário de Avaliação de Qualidade de Vida no Trabalho (IA_QVT) e foram analisados com o aplicativo IRaMuTeQ. Os resultados apontaram três núcleos temáticos estruturadores do discurso para bem-estar no trabalho (relacionamento com colegas, fazer trabalho que gosta e sentir-se útil à sociedade) e mal-estar no trabalho (sobrecarga de trabalho, falta de reconhecimento e pressão temporal e retrabalho). A gestão sustentável de QVT, portanto, deve estar ancorada em práticas de gestão de pessoas que fomentem o investimento no desenvolvimento dos profissionais, o alinhamento das tarefas e papéis com a missão organizacional, evidenciando a conexão com as contribuições sociais, o reconhecimento do trabalhador por superiores, pares e sociedade, a revisão da organização do trabalho, com foco na reavaliação de processos de trabalho, distribuição de demandas e formas de pactuação e cobrança de resultados.

The effectiveness of inter-municipal cooperation for integrated sustainable waste management: A case study in Ecuador.

There is an increasing awareness that effective waste management is essential for transitioning towards a circular economy and achieving sustainable development goals. Scholars have studied inter-municipal cooperation (IMC) as a governance solution with the potential to generate economies of scale and reduce financial costs in waste management. However, previous research has not yet focused on measuring the effectiveness of different types of cooperation on social and environmental outcomes. We analyse the effect of different types of IMC, ranging from indirect to collaborative, on Integrated Solid Waste Management (ISWM) indicators. Our embedded qualitative case study in the emerging metropolitan region of Cuenca-Azogues (Ecuador) found that municipalities that invested in more complex cooperation types achieved better integrated waste management performance, particularly on final disposal, citizen participation, inclusion of recyclers and environmental sustainability.

New Sensors for Monitoring pH and Corrosion of Embedded Steel in Mortars during Sulfuric Acid Attack.

The sulfuric acid attack is a common form of degradation of reinforced concrete in contact with industrial wastewater, mine water, acid rain, or in sewage treatment stations. In this work, new pH-sensitive IrOx electrodes were developed for monitoring the pH inside mortar or concrete. To test their ability, the pH sensors were embedded in mortar samples at different depths and the samples were exposed to sulfuric acid solution. In another set of experiments, iron wires were placed at the same depths inside similar mortar samples and their corrosion was monitored as the acid attacked the mortar. Severe acid attack led to cement dissolution and formation of gypsum. The new pH sensors succeeded in measuring the pH changes inside the mortars. The pH gradient, from the high acid environment to the high alkaline mortar interior, occurred in a narrow region. Corrosion of the iron electrodes started only when the acidic solution was in their close vicinity.

Trophic niche changes associated with the eradication of invasive mammals in an insular lizard: an assessment using isotopes.

Invasive species are a major threat to island biodiversity, and their eradications have substantially contributed to the conservation of island endemics. However, the consequences of eradications on the trophic ecology of native taxa are largely unexplored. Here, we used the eradication of invasive black rats Rattus rattus and European rabbits Oryctolagus cuniculus from the Berlenga Island, in the western coast of Portugal, as a whole-ecosystem experiment to investigate the effects of the eradication of invasive mammals on the trophic niche and body dimensions of the island-restricted Berlenga wall lizard Podarcis carbonelli berlengensis over a 2-year period. Our results suggest an expansion of the isotopic niche and an intensification of the sexual dimorphism of the lizard following mammal eradication. Additionally, we found considerable variability in isotopic niche across the island and detected evidence of sex-specific and season-modulated nutritional requirements of this threatened reptile. Our findings support that the eradication of 2 of the planet's most problematic invasive vertebrates led to changes in the lizard trophic niche and sexual dimorphism in just 2 years. This suggests that the ecological pressures-for example, prey availability and habitat structure-to which lizards are exposed have substantially changed post-eradication. Our study emphasizes the scientific value of island eradications as experiments to address a wide range of ecological questions and adds to the increasing body of evidence supporting substantial conservation gains associated with these restoration interventions.

Complications in intraoral versus external approach for surgical treatment of Eagle syndrome: A systematic review and meta-analysis.

OBJECTIVE: The surgical treatment of Eagle syndrome involves an intra- or extraoral approach. This systematic review set out to consolidate current knowledge on the prevalence of complications associated with intraoral and external approaches. METHODS: Seven main electronic and two gray literature databases were searched. Studies were blindly selected by two reviewers based on pre-defined eligibility criteria. Studies evaluating any type of complication in the treatment of Eagle syndrome were considered eligible. Risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for studies reporting prevalence data, case reports, and case series. The Comprehensive Meta-Analysis software (Software version 3.0 - Biostat, Englewood, NJ, USA) was used to perform all meta-analyses. RESULTS: Out of 1728 articles found on all databases, 36 were included for qualitative analysis. Twenty were included for quantitative analysis and meta-analysis. CONCLUSION: In this study, the highest rate of complications was found in the intraoral approach.

Fatal necrotizing fasciitis following a non-treated mandibular fracture: case report / Fasciíte necrotizante fatal devido a fratura mandibular não tratada: relato de caso

ABSTRACT Necrotizing fasciitis is a rare and severe infection characterized by extensive and quickly progressing necrosis of the subcutaneous tissue and muscle fascia associated with high mortality rates in the head and neck region. We present a case of fatal necrotizing fasciitis due to an untreated mandibular fracture. Eight days after the trauma, the patient was admitted to the hospital and died on the sixth day of hospitalization.

RESUMO Fasciite necrosante é uma infecção rara e grave caracterizada por necrose extensa e de rápida progressão do tecido subcutâneo e fáscia muscular associada a altas taxas de mortalidade na região da cabeça e pescoço. Apresentamos um caso de fasciite necrosante fatal devido a uma fratura mandibular não tratada. Oito dias após o trauma, o paciente deu entrada no hospital e faleceu no sexto dia de internação.

Is Zirconia Better Than Titanium Abutments for Soft Tissue Color? A Systematic Review and Meta-analysis of Spectrophotometric Evaluation.

PURPOSE: The aim of this systematic review was to evaluate the influence of zirconia and titanium as abutment materials on peri-implant soft tissue color. MATERIALS AND METHODS: The searched electronic databases included MEDLINE/PubMed, LILACS, Web of Science, Scopus, and LIVIVO. Two types of studies were included: randomized clinical trials (RCTs) and controlled clinical trials (CCTs) that compared zirconia (Zr) and titanium (Ti) abutments. The outcomes measured were as follows: implant crown esthetic index, visual analog scale, esthetic index, gingiva discoloration index-spectrophotometry, papilla index, recession index, and pink esthetic score. Two reviewers selected the records, assessed quality, and extracted data of included studies independently. RESULTS: A total of 323 patients enrolled in 13 studies were included in this analysis with 11 RCTs and 2 CCTs. Due to the wide variety of methodologies used, meta-analysis was only possible for RCTs that performed spectrophotometric analysis. The use of zirconia or titanium for implant abutments does not seem to be the principal factor for influencing peri-implant soft tissue color. The meta-analysis showed no difference between zirconia and titanium abutments. CONCLUSION: This study does not support any better advantage of the use of zirconia in comparison to the use of titanium related to peri-implant tissue color.

Perceived Causes and Attitudes Regarding Overindebtedness and Their Effects on Public Agreement With Government Financial Aid.

In order to better understand how the problem of overindebtedness is perceived from a laypeople standpoint, Study 1 inquired both overindebted and non-overindebted consumers on the perceived causes of and attitudes toward the overindebted. Situational and dispositional factors were perceived to have similar impact as causes of overindebtedness, but non-overindebted consumers showed stronger agreement with those causes than overindebted consumers. Regarding attitudes, non-overindebted consumers tended to blame overindebted people for their situation rather than perceiving them as victims, whereas overindebted consumers showed the opposite pattern. Study 2 used a sample of (non-overindebted) consumers to assess the impact of perceived causes of overindebtedness, attitudes toward the overindebted, and political orientation on public support of government policies for aiding overindebted people. We discuss the contributions of the present findings to design public policies aimed at aiding overindebted households that are more aligned with the beliefs and attitudes of the general public.

Attitudes Toward Money and Control Strategies of Financial Behavior: A Comparison Between Overindebted and Non-overindebted Consumers.

This paper addresses whether overindebted and non-overindebted consumers differ in their attitude toward money (specifically, the degree to which consumers care about money and feel difficulties keeping track of their money) and how this attitude impacts three different financial behavior categories: record keeping (e.g., recording spending in writing), adjusting balance (e.g., trying to find ways to decrease one's expenses to match income), and monitoring balance (e.g., monitoring one's spending to see if it is in line with what is expected). Overindebted consumers were recruited via an NGO for consumer defense and were categorized (whenever possible) into two subgroups: consumers who became overindebted due to internal causes (e.g., bad financial management) and consumers who became overindebted due to external causes (e.g., unemployment). Non-overindebted consumers were a convenience sample. Non-overindebted consumers showed more positive attitudes toward money than both groups of overindebted consumers and overindebted due to external causes showed more positive attitudes than overindebted consumers due to internal causes. All groups share similar financial management behaviors except for monitoring balance, which was more frequent among non-overindebted consumers. Furthermore, a regression analysis indicates that money attitudes helped explain financial behavior differences between consumers above and beyond their indebtedness status. Consumers' attitude predicted financial behaviors, even when controlling for relevant socioeconomic variables (education, income, age, and gender). Further analyses comparing money attitudes and financial behavior for the three subgroups (non-overindebted, overindebted due to internal causes, and overindebted due to external causes) showed no differences.

On the Relation Between Over-Indebtedness and Well-Being: An Analysis of the Mechanisms Influencing Health, Sleep, Life Satisfaction, and Emotional Well-Being.

This paper aims to explore the association between over-indebtedness and two facets of well-being - life satisfaction and emotional well-being. Although prior research has associated over-indebtedness with lower life satisfaction, this study contributes to the extant literature by revealing its effects on emotional well-being, which is a crucial component of well-being that has received less attention. Besides subjective well-being (SWB), reported health, and sleep quality were also assessed. The findings suggest that over-indebted (compared to non-over-indebted) consumers have lower life satisfaction and emotional well-being, as well as poorer (reported) health and sleep quality. Furthermore, over-indebtedness impacts life satisfaction and emotional well-being through different mechanisms. Consumers decreased perceived control accounts for the impact of over-indebtedness on both facets of well-being (as well as on reported health and sleep). Financial well-being (a specific component of life satisfaction), partly mediates the impact of indebtedness status on overall life satisfaction. The current study contributes to research focusing on the relationship between indebtedness, well-being, health, and sleep quality, and provides relevant theoretical and practical implications.

A diffusion model analysis of belief bias: Different cognitive mechanisms explain how cognitive abilities and thinking styles contribute to conflict resolution in reasoning.

Recent results have challenged the widespread assumption of dual process models of belief bias that sound reasoning relies on slow, careful reflection, whereas biased reasoning is based on fast intuition. Instead, parallel process models of reasoning suggest that rule- and belief-based problem features are processed in parallel and that reasoning problems that elicit a conflict between rule- and belief-based problem features may also elicit more than one Type 1 response. This has important implications for individual-differences research on reasoning, because rule-based responses by certain individuals may reflect that these individuals were either more likely to give a rule-based default response or that they successfully inhibited and overrode a belief-based default response. In two studies, we used the diffusion model to describe decision making in a transitive reasoning task. In Study 1, 41 participants were asked to evaluate conclusions based on their validity. In Study 2, 133 participants evaluated conclusions based on their validity or believability. We tested which diffusion model parameters reflected conflict resolution and related those model parameters to individual differences in cognitive abilities and thinking styles. Individual differences in need for cognition predicted successful conflict resolution under logic instruction, which suggests that a disposition to engage in reflective thinking facilitates the inhibition and override of Type 1 responses. Intelligence, however, was negatively related to successful conflict resolution under belief instruction, which suggests that individuals with high cognitive abilities quickly generated a higher-level logical response that interfered with their ability to evaluate lower-level intrinsic problem features. Taken together, this double dissociation indicates that cognitive abilities and thinking styles affect the processing of conflict information through different mechanisms and at different stages: Greater cognitive abilities facilitate the efficient creation of decoupled problem representations, whereas a greater disposition to engage in critical thinking facilitates the detection and override of Type 1 responses.
