Medical Assistance in Dying: A Review of Canadian Nursing Regulatory Documents
Authors: Pesut Barbara , Thorne Sally , Stager Megan L. , Schiller Catharine J. , Penney Christine , Hoffman Carolyn , Greig Madeleine , Roussel Josette
Published: May 2019

Canada's legalization of Medical Assistance in Dying (MAiD) in 2016 has had important implications for nursing regulators. Evidence indicates that registered nurses perform key roles in ensuring high-quality care for patients receiving MAiD. Further, Canada is the first country to recognize nurse practitioners as MAiD assessors and providers. The purpose of this article is to analyze the documents created by Canadian nursing regulatory bodies to support registered nurse and nurse practitioner practice in the political context of MAiD. A search of Canadian provincial and territorial websites retrieved 17 documents that provided regulatory guidance for registered nurses and nurse practitioners related to MAiD. Responsibilities of registered nurses varied across all documents reviewed but included assisting in assessment of patient competency, providing information about MAiD to patients and families, coordinating the MAiD process, preparing equipment and intravenous access for medication delivery, coordinating and informing health care personnel related to the MAiD procedure, documenting nursing care provided, supporting patients and significant others, and providing post death care. Responsibilities of nurse practitioners were identified in relation to existing legislation. Safety concerns cited in these documents related to ensuring that nurses understood their boundaries in relation to counseling versus informing, administering versus aiding, ensuring safeguards were met, obtaining informed consent, and documenting. Guidance related to conscientious objection figured prominently across documents. These findings have important implications for system level support for the nursing role in MAiD including ongoing education and support for nurses' moral decision making.
Bullying in Nursing: Is it in the Eye of the Beholder?
Authors: Hartin Peter , Birks Melanie , Lindsay David
Published: May 2019

The nursing profession is presented with numerous definitions of workplace bullying. This study provides an in-depth analysis of the concept of bullying in the nursing profession in Australia through a scoping review of definitions presented in literature published up until 2018. The research questions used to guide the search were as follows: How has the definition of bullying in nursing in Australia been conceptualized in the literature? How do these definitions of bullying differ? How has the definition of bullying, as used in the literature, evolved over time? The review was informed by the approach of Arksey and O’Malley, containing explicit definitions of bullying in nursing literature. The findings reveal that the literature does not reflect a shared and integrated vision of the exact nature of bullying in the nursing profession. The conceptualization of bullying in the nursing profession has become more dynamic over time. The myriad ways in which bullying in nursing is defined in Australia has important implications for research, practice, education, and policy.
Finite-time tracking control for uncertain robotic manipulators using backstepping method and novel extended state observer
Authors: Chen Chao , Zhang Chengrui , Hu Tianliang , Ni Hepeng , Chen Qizhi
Published: May 2019

This article considers finite-time trajectory tracking control problem for robotic manipulators with parameter uncertainties and external disturbances. A finite-time controller that achieves high precision and strong robustness is proposed without the requirement of the exact dynamic model. First, a novel finite-time model-assisted extended state observer is designed to compensate the system uncertainties with complex and uncertain dynamics. Then, a composite finite-time controller is developed for trajectory tracking control with the help of finite-time model-assisted extended state observer. Compared to the classic extended state observer, it is proved that the estimation error of finite-time model-assisted extended state observer can be stabilized in finite time. Meanwhile, the finite-time convergence of the closed-loop system with the proposed controller can also be proved through Lyapunov’s stability theory. A variable structure term is employed to compensate the estimation errors of finite-time model-assisted extended state observer. The validity of the control scheme is demonstrated by simulations and experiments.
Cryoprobe biopsy for the diagnosis of acute hypoxemic respiratory failure of undetermined origin
Authors: Heras Marcos J Las , Dianti Jose , Tisminetzky Manuel , Svetliza Graciela , Giannasi Sergio E , Roman Eduardo San
Published: May 2019

Rationale

Acute hypoxemic respiratory failure is a condition that comprises a wide array of entities. Obtaining a histological lung sample might help reach a diagnosis and direct an appropriate treatment in a select group of patients.

Objective

To describe our experience in the use of cryobiopsy for the diagnosis of acute hypoxemic respiratory failure of undetermined origin.

Methods

Retrospective analysis of case series of patients with acute hypoxemic respiratory failure who underwent lung cryobiopsy at the Intensive Care Unit of the Hospital Italiano de Buenos Aires, Argentina.

Results

Cryobiopsy yielded a histological diagnosis in all patients ( n = 10, 100%). This led to either a change in therapy or continuation of a specific treatment in eight of these patients. Cryobiopsy was found to be contributive in all the patients who did not meet Berlin criteria for acute respiratory distress syndrome. No major complications were associated with the procedure.

Conclusions

Cryobiopsy is a safe procedure with a high diagnostic yield in a selected group of patients.
Inhibitory Activity on Amyloid Aggregation of Rosmarinic Acid and Its Substructures From Isodon japonicus
Authors: Sun Jiayi , Jiang Gandan , Shigemori Hideyuki
Published: May 2019

Nowadays, the incidence of Alzheimer’s disease (AD) and type 2 diabetes (T2D) is increasing at an alarming rate. More and more studies have been investigating the relationship between these two diseases and are trying to find an effective treatment. According to amyloid hypothesis, it is very necessary to find phenolic compounds with catechol moieties, which would inhibit the aggregation of amyloid β (Aβ) and human islet amyloid polypeptide (hIAPP), while also exhibiting antioxidant activity and protective effect. We isolated rosmarinic acid (RA) from the plant Isodon japonicus (Burm.f.) H. Hara. Thioflavin T assay and transmission electron microscopy observation were carried out to evaluate the inhibitory effect of RA, caffeic acid, and 3,4-dihydroxyphenyllactic acid, which are the substructures of RA, on both Aβ and hIAPP fibrillization. 2,2-Diphenyl-1-picrylhydrazyl assay was applied to test the antioxidant activity. RA showed inhibitory effect on both peptides and strong antioxidant activity. These results suggest that the existence of catechol units plays an important role on the inhibitory activity. Therefore, RA will be a promising strategy to prevent AD and T2D.
Testing Cold and Hot Cognitive Control as Moderators of a Network of Comorbid Psychopathology Symptoms in Adolescence

Published: May 2019

Comorbidity is pervasive across psychopathological symptoms, diagnoses, and domains. Network analysis is a method for investigating symptom-level associations that underlie comorbidity, particularly through bridge symptoms connecting diagnostic syndromes. We applied network analyses of comorbidity to data from a population-based sample of adolescents ( N = 849). We implemented a method for assessing nonparametric moderation of psychopathology networks to evaluate differences in network structure across levels of intelligence and emotional control. Symptoms generally clustered by clinical diagnoses, but specific between-cluster bridge connections emerged. Internalizing symptoms demonstrated unique connections with aggression symptoms of interpersonal irritability, whereas externalizing symptoms showed more diffuse interconnections. Aggression symptoms identified as bridge nodes in the cross-sectional network were enriched for longitudinal associations with internalizing symptoms. Cross-domain connections did not significantly vary across intelligence but were weaker at lower emotional control. Our findings highlight transdiagnostic symptom relationships that may underlie co-occurrence of clinical diagnoses or higher-order factors of psychopathology.
Microfracture of subchondral bone leads to persistent subchondral sclerosis and poorer functional outcomes following distraction arthroplasty of the ankle joint while biologic augment may improve recovery times

Ankle Arthritis

Introduction/Purpose:

Treatment of ankle osteoarthritis (OA) continues to remain a challenge. Previous reports have demonstrated the short-term benefits of using joint distraction for the treatment of ankle (OA), however, its efficacy in long term clinical outcomes and its role in preserving the joint space remains controversial. The purpose of this study is to establish whether microfracture or biologics improve the outcomes of ankle distraction.

Methods:

Records of patients that underwent an ankle distraction procedure between January 2009-December 2013 were retrospectively reviewed. Four groups were identified: Group 1: distraction with no additional treatment, Group 2: distraction with microfracture, Group 3: distraction with microfracture and BMAC/PRP, Group 4: distraction with BMAC/PRP. Demographic data was recorded. Pre-and-postoperative range of motion, Foot and Ankle Outcome Scores (FAOS), complication rate, and return to activity were evaluated. Radiographic images were used to assess the joint space changes pre-operatively and post-operatively. Global comparisons were performed using chi square testing, while individual between-group comparisons were made using robust, resistant regression and Wald tests.

Results:

Eighty-one patients with a mean age of 47 (range, 37-69) underwent ankle distraction with a mean follow up of 5 years (range, 3-6). All treatment strategies resulted in statistically significant improvements in FAOS (<0.001). Groups that underwent microfracture had a statistically significant decrease in post-operative plantarflexion, dorsiflexion, subtalar inversion and subtalar eversion (p=0.003) as well as an overall decrease in joint space (0.002) with persistence of subchondral bone sclerosis. Patients who underwent distraction with no microfracture treatment resulted in a significant increase in post-operative joint space (p=0.001) and decreased sclerosis in the subchondral bone. Average return to activity was 6 months in patients who received BMAC/PRP with ankle distraction compared to 12 months in patients who were treated with ankle distraction and microfracture (p<0.01).

Conclusion:

Distraction arthroplasty results in good functional outcomes at medium term follow up. The addition of microfracture seems to create functional outcome deterioration, whereas the addition of a biologic agent either BMAC or PRP appears to benefit earlier return to function. Longer-term studies will be required to see if these effects are sustained.
Hallux Valgus
Authors: Ray Justin J. , Friedmann Andrew J. , Hanselman Andrew E. , Vaida Justin , Dayton Paul D. , Hatch Daniel J. , Smith Bret , Santrock Robert D.
Published: May 2019

Hallux valgus is a common condition that results from a complex positional deformity of the first ray. The bunion or medial prominence that results from the lateral deviation and pronation of the hallux is only one component of the 3-dimensional deformity. Hallux valgus can lead to considerable pain and altered joint mechanics. The precise biomechanical etiology remains under debate. Predisposing factors include female sex, age, constricting footwear, and family history. Metatarsus adductus, equinus contracture, hammertoe deformity, and pes planus often coexist with hallux valgus. Nonoperative treatment involves patient education, shoe modifications, toe pads and positioning devices, and activity modifications. Surgery is considered in patients who fail nonoperative treatment with the goal of pain relief, correction of the deformity, improved first ray stability, and improved quality of life. More than 100 different procedures have been described to treat hallux valgus; they include combinations of soft tissue balancing, metatarsal osteotomies, and fusion of either the metatarsophalangeal (MTP) or tarsometatarsal (TMT) joint. The choice of procedures depends on the severity and location of the deformity as well as surgeon preference. Recent advances in operative techniques include minimally invasive surgery and correction of rotational deformity.
Ship Traffic Optimization for the Kiel Canal
Authors: Lübbecke Elisabeth , Lübbecke Marco E. , Möhring Rolf H.
Published: May 2019

In “Ship Traffic Optimization for the Kiel Canal,” Lübbecke, Lübbecke, and Möhring develop graph-based models and algorithms to solve a practical traffic scheduling problem. It arises in the operational planning of bidirectional traffic where vehicles can pass each other only at dedicated locations—e.g., vessels that navigate narrow waterways. The authors provide decision support for the particular planning problem at the German Kiel Canal, the world’s most frequented artificial waterway, but their findings generalize, e.g., to scheduling trains on a stretch of single tracks or collision-free routing of robot arms. Mathematically, these planning problems expose a rich combinatorial structure. Ideas from quickest path algorithms and job-shop scheduling are integrated to handle all practical constraints at a high level of detail. The modelling does not need any time or space discretization. The software tool developed during the study was also used to assess strategic options of enlarging the canal.
Uma trama tecida com muitos fios: o pesquisar como processo artesanal na Teoria Ator-Rede
Authors: Quadros Laura Cristina de Toledo
Published: May 2019

O presente artigo pretende discutir a experiência de pesquisar como uma prática artesanal, tendo como referência metodológica a Teoria ator-rede que, através de sua proposta, nos permite compreender que a pesquisa está sujeita a desvios e recalcitrâncias. Considerando o pesquisar como um processo único, onde cada campo convoca peculiaridades e ações diferenciadas, aproximamos essa prática à construção artesanal em que o fazer também se constitui de modo não linear. A inspiração artesanal eleita como base foi a arte de tecer com fios, em especial a arte de "crochetar", emergindo aqui uma herança feminina que nos atravessa. Compreendemos que os modos de fazer só podem ser acompanhados na prática, e nos interessa discutir como se processa o pesquisar articulado à vida como uma política ontológica.

Este artigo objetivou apresentar resultados de pesquisa sobre documentos do Fundo das Nações Unidas para a Infância (UNICEF), referentes ao tema adolescentes e drogas. Como metodologia, foi realizada uma análise histórica documental, a partir de ferramentas teóricas e metodológicas da História Cultural e da Psicologia Social e Institucional, as quais constituíram os arcabouços deste trabalho. Entre os documentos selecionados da página do UNICEF na internet, durante o período da Nova República brasileira, desde a aprovação do Estatuto da Criança e do Adolescente, em 1990, até 2012, estão relatórios específicos sobre a situação da adolescência brasileira. Foram trabalhadas práticas acionadas por essa agência multilateral frente à questão das drogas e dos adolescentes, sendo interrogadas e analisadas em seus efeitos e delineamentos, na garantia de direitos desse segmento social. Entre os resultados, é possível destacar a tentativa do UNICEF em afirmar uma visão de vulnerabilidade dos adolescentes face às drogas e um conjunto de recomendações ao Brasil para lidar com essa situação.
Trabalho e suicídio: gesto de resistência final
Authors: Campos Luciene Jung de , Alquatti Raquel , Garbin Stefany Rettore , Pereira Ismael
Published: May 2019

O artigo propõe um gesto de leitura de três processos judiciais sobre suicídio e trabalho. Os casos levantados junto ao Memorial do Judiciário do Estado do Rio Grande do Sul correspondem às décadas de 1960 e 1970. Apresentados aqui na interface entre as duas disciplinas de origem dos autores, Psicologia e História, e entre duas obras: Suicídio e Trabalho: o que fazer? de Christophe Dejours e Florence Bègue (2010) e Sobre o Suicídio de Karl Marx (1846/2006). A Análise de Discurso é o dispositivo teórico analítico que proporciona essa interface sendo conhecimento de entremeio entre Psicanálise, Materialismo Histórico e Linguagem, através do qual procuramos analisar os efeitos de evidência presentes nos processos judiciais. O que quer saber um processo criminal de suicídio? Observamos que os processos trabalhados procuram cúmplices e culpados encarnados. O suicídio é um gesto absoluto e silenciado, tratado como um ato individual e, portanto, atribuído ao seu autor. Pouco se discute acerca do suicídio ou da situação em que é praticado. Menos ainda, a relação do suicídio com a sociedade em que é concebido. Perde-se o sujeito que engendra o gesto. Resta o sujeito autor na condição de depositário: causa e consequência de sua própria ação.

Como modelo micropolítico da atenção psicossocial, cartografamos o CAPS UERJ como acontecimento, recorte evidenciado pelas narrativas dos sujeitos implicados com as suas emergências. O recurso genealógico, criado por Nietzsche ao final do século XIX e desdobrado por Michel Foucault no século seguinte, forneceu pistas para demonstrarmos as aproximações da pesquisa ao movimento de ruptura com o Hospital Dia Ricardo Montalban, representado pelo modelo psiquiátrico hospitalocêntrico medicalizador, para a emergência do CAPS UERJ e seu alinhamento com a estratégia da atenção psicossocial. Contudo, a tentativa de tradução da processualidade desse movimento evidencia rupturas, capturas e (des)continuidades do dispositivo-acontecimento pelo analisador supervisão clínico-institucional.Palavras-chaves: Reforma Psiquiátrica; Estratégia da Atenção Psicossocial, Dispositivo-Acontecimento.  Abstract —We map the CAPS UERJ as a micro-political model of psychosocial care event cutting evidenced by the narratives of subjects involved into their emergencies.

However, the attempt to translate the processuality of this movement reveals catches and (dis) continuity of the device event by clinical-institutional supervision analyzer.Keywords: Psychiatric reform; Psychosocial care strategy; Device-events; CAPS UERJ.
Violência estrutural contra mulheres em Belo Monte: o que os dados oficiais (não) revelam | Structural violence against women in Belo Monte: what official data does not reveal
Authors: Barroso Milena Fernandes
Published: May 2019

A experiência de Belo Monte é emblemática por explicitar a violência contra as mulheres como condição. Neste sentido, o presente artigo trata de uma aproximação às expressões da violência de gênero neste contexto, a partir da análise dos registros oficias de violência contra as mulheres antes e depois do início das obras da UHE de Belo Monte. São problematizadas, assim, as análises que percebem o aumento dos registros como mera coincidência ou buscam uma explicação na condição masculina – no sentido de uma essência ou estrutura psicológica masculina naturalmente violenta e inabalável. A análise aponta para o distanciamento entre os dados oficiais e a realidade concreta, posto que os registros não alcançam a multiplicidade de expressões da violência no cotidiano das mulheres. Afirma-se também que a violência contra as mulheres não figura apenas como consequência ou resultado desses projetos: ela é determinante para que esses projetos possam se constituir como tal. Palavras-Chave: violência contra as mulheres; violência estrutural; Usina Hidrelétrica de Belo Monte. Abstract – Belo Monte’s experience is remarkable because it exposed violence against women as a condition. Therefore, this article is about an approximation to the expressions of violence against women before and after the beginning of the work at the Belo Monte Dam. Analyses that perceive the increase in reports as simple coincidence or that seek an explanation in the male condition – understood as a naturally violent and unyielding essence or psychological structure – are problematized. The conclusion points to a divergence between official data and concrete reality, since records do not reflect the multiplicity of expression of violence to which women are routinely subjected. It also states that violence against women does not appear only as a result or consequence of these projects, it is necessary to their very establishment.Keywords: violence against women; structural violence; Belo Monte Hydropower.

Study on prevalence, clinical presentation, and associated bacterial pathogens of goat mastitis in Bauchi, Plateau, and Edo states, Nigeria
Authors: Danmallam Faruq Ahmad , Pimenov Nikolai Vasilyevich
Published: May 2019

Aim: This study aimed to estimate the prevalence and clinical presentations of different forms of mastitis and mastitis-causing pathogens in lactating goats in Bauchi, Plateau, and Edo states, Nigeria.

Materials and Methods: A total of 500 quarters from 250 lactating goats of Red Sokoto and West African Dwarf breeds during the lactation period were clinically examined. Clinical mastitis was detected by gross signs of udder infection during physical examination and abnormal milk, whereas subclinical mastitis (SCM) was recognized using California mastitis test. The bacterial pathogens were identified by morphology, hemolysis, gram staining, and biochemical tests such as catalase, oxidase, coagulase, reaction on sulfite, indole, and motile medium, and fermentation of sugars.

Results: The overall prevalence of mastitis in goats was found to be 101 (40.4%), of which 8% (20/250) were clinical, and 32.4% (81/250) were SCM cases. The quarter level prevalence was 29.4% (145/493), comprising 5.9% (29/493) clinical and 23.2% (116/493) subclinical forms of mastitis. In addition, 1.4% (7/500) of teats were found to be blind on the clinical examination of the udder and teat. Several regional inflammatory reactions and abnormalities in milk were found in 69% and 100% of the cases, respectively. Moreover, some indications of generalized signs such as fever, reduction in appetite, increase in respiration, and pulse rate per minute were recorded in 100%, 75%, 85% and 80% of the cases, respectively. The predominant bacterial isolates recovered were Staphylococcus aureus (20.0%), followed by Escherichia coli (15.5%) and Streptococcus agalactiae (11.0%), and the least isolated microorganisms (≤6%) were bacteria of different species including Staphylococcus auricularis, Staphylococcus caprae, Staphylococcus chromogenes, Staphylococcus epidermidis, Staphylococcus hyicus, Staphylococcus xylosus, Staphylococcus lentus, Streptococcus dysgalactiae, Streptococcus pluranimalium, Streptococcus uberis, Streptococcus pneumoniae, Streptococcus ruminatorum, Streptococcus suis, Micrococcus luteus, Enterobacter cloacae, Proteus vulgaris, Klebsiella oxytoca, Klebsiella pneumoniae, Morganella morganii, Salmonella Typhimurium, Citrobacter freundii, Pseudomonas aeruginosa, Acinetobacter rudis, Acinetobacter haemolyticus, and Bacillus cereus.

Conclusion: Mastitis continues to be recognized as one of the important health issues and leads to major economic losses to the dairy goats caused by many bacterial pathogens, and the effective measures need to be taken to control the disease.

Unsichere Arbeit

Published: May 2019

Die Sorgen und Ängste von Arbeitnehmerinnen und Arbeitnehmern im Hotel- und Gaststättengewerbe in Berlin und Brandenburg stehen im Fokus dieser Untersuchung. Im Gastgewerbe sind flexible sowie überlange Arbeitszeiten und geringfügige Beschäftigung weit verbreitet. Zudem kamen vor der Einführung des Mindestlohns im Jahr 2014 niedrig entlohnte Beschäftigungsverhältnisse im Branchenvergleich besonders häufig vor. Insbesondere bei den Beschäftigten mit niedrigen Löhnen sollte der im Januar 2015 in Kraft getretene gesetzliche Mindestlohn Lohnsteigerungen auf 8,50 Euro und mehr bewirken und damit Arbeitnehmerinnen und Arbeitnehmer vor Dumpinglöhnen und Ausbeutung schützen. Um die Effekte des Mindestlohns beurteilen zu können, wurden Beschäftigte im Gastgewerbe mit Leitfadeninterviews befragt. Aus der Perspektive der Befragten kann die Einführung des gesetzlichen Mindestlohns in Deutschland als Wegbereiter in Richtung mehr Lohngerechtigkeit gesehen werden. Zudem sind viele Beschäftigte im Gastgewerbe mit ihrer Arbeit überwiegend zufrieden. Gleichzeitig berichten sie von einer geringen Wertschätzung am Arbeitsplatz und sind in latenter Sorge um ihren Arbeitsplatz. Nahezu jederzeit austauschbar zu sein geht mit Arbeitsplatzverlustängsten einher. Diese Sorgen und Ängste sind ein Ausdruck von prekären Beschäftigungsverhältnissen und sind plausibel: Denn gerade in Zeiten des Fachkräftemangels ist individuelle Arbeitslosigkeit besonders schwer zu ertragen.
Würde - mehr als eine Worthülse?

Im Blick auf Letzteres gilt zudem: Die eigenen Interessen sollten gleich zählen wie die Interessen anderer.
Humanitäre Interventionen - ein zweischneidiges Schwert
Authors: Zanetti Véronique
Published: May 2019

Véronique Zanetti widmet sich der Analyse des moralischen Dilemmas, mit dem die Rechtfertigung humanitärer Interventionen unweigerlich konfrontiert ist. Das Dilemma entsteht aus einer Kollision von Pflichten: der Pflicht, Menschen in Not zu helfen, und der Pflicht, Unschuldigen keinen Schaden zuzufügen. Die Literatur über gerechte Kriege favorisiert zwei Strategien, um einen Ausweg zu finden. Die erste (das Prinzip der Doppelwirkung) unterscheidet zwischen einem absichtlich verfolgten Ziel und der nicht intendierten Folge der Handlung. Die zweite Strategie (das Prinzip der Verhältnismäßigkeit) setzt dem Prinzip der Doppelwirkung eine quantitative Grenze. In Wirklichkeit laufen beide Strategien Gefahr, Kriegen und Kriegsverbrechen zu schwache normative Riegel vorzuschieben. Ich werde die beiden Strategien und einige Kritiken daran näher untersuchen und zeigen, dass die von ihnen beabsichtigte Rechtfertigung eines Krieges in einen Kompromiss zwischen zwei inkompatiblen Positionen mündet: einer, die das Immunitätsprinzip von Zivilisten vertritt, und einer, die seine Auswirkung lindert.
Produkowanie estetyk, produkowanie podmiotu. Początki odwilży i wolność twórcza w sztukach wizualnych na przykładzie wystawy w Arsenale
Authors: Dąbrowski Jakub
Published: May 2019

In Polish art history, there are two approaches to the “Arsenał” exhibition of August 1955. One, rooted in the debates around it, presents the “Arsenał” as the beginning of a political “thaw” – an act of emancipation, a demonstration of young artists who rebelled against the socialist realism. The other approach to the show or, rather, to the “thaw” as a whole, rejects an interpretation of artistic processes and choices as autonomous activities. Instead, with reference to the theory of Michel Foucault, the “Arsenał” is considered as a result of a reconfiguration of scattered power relations, stimulated by the changing strategies of the institutional power system. The present paper follows the latter approach. Foucault claims that power relations are combined with three interconnected types of human relations: defining the hierarchy of tasks and division of labor, compelling obedience, and performing “communicative binding,” i.e. purposeful action that affects the actors’ knowledge of the world and of themselves. After 1954, power relations in Poland were strategically changing: the system of labor division and the distribution of art, including all the related benefits, was still centralized, but the ineffective administrative control relaxed, while the production of meaning changed as well – the communist party modified its rhetoric referring to art and the range of artistic choice grew together with the options of communication. Still, the liberalization of the system and abandoning the Moscow version of the socialist realism in cultural policy did not mean any real increase of the freedom of choice. Using state exhibition institutions and the press, which was the main channel of communication between the authorities and the masses, the communist regime continued to control the aesthetic consciousness of the artists. An analysis of both printed and visual messages found in the press of the period, specialist periodicals and daily newspapers alike, has revealed a surprising similarity of the official discourse and the aesthetic choices made by the participants of the “Arsenał” – in particular those choices which were later interpreted as attempts to reject the socialist realism and launch a new beginning. It seems that the young artists were “positively censored,” i.e. the regime succeeded in creating an aesthetic reality which they accepted. What is more, they considered it subversive as an emanation of liberty. The selection of the aesthetic modes favored by the authorities took place in an unconscious way already at the stage of creation, before particular works of art were accepted by the ”Arsenał” jury and before they were actually controlled by the institutions of censorship.
Das Parlament der Dinge: Transmateriale und transmediale Dynamiken, Bild-Ding-Relationen und „Meta-Artefakt-Malerei“
Authors: Schulz Vera-Simone
Published: May 2019

Studies related to artifacts, to what has been traditionally categorized as ‘high’ and ‘minor’ or ‘applied arts’, and to the materiality of art in recent years have been among the core foci of art history. More scholarly attention has also been given to the intersections between visual and material culture, not least in transcultural contexts. This paper seeks to contribute to these issues. Investigating transmaterial and transmedial dynamics between the arts, image-object interrelations as well as phenomena wherein images themselves gave the impulse to the creation of artifacts, the paper analyzes transfer processes transgressing various media and materials, 15th- and 16th-century Italian and Portuguese paintings in their Mediterranean and global entanglements, as well as 19th - and 20th-century artistic and academic approaches to objects in paintings.
Poręczne obrazy, wymowne przedmioty. Retoryka rzeczowości w „L'Esprit Nouveau” Ozenfanta i Le Corbusiera
Authors: Rejniak-Majewska Agnieszka
Published: May 2019

The paper is an attempt to draw the reader’s attention to visual reproduction as an element of modern artistic discourses and a medium of the mediated reception of art. An instrumental approach to reproduction as a neutral and ancillary vehicle of meaning, prevalent in the age of modernism, corresponded to the belief in its information efficacy and ability to overcome material, physical limitations. What mattered most were not the material, physical aspects of the existence and circulation of images, even though the avant-garde artists of the 1920s, using contemporary technology, were aware how important the medium’s and its distribution range’s “impact” was. L’Esprit Nouveau, a periodical edited in 1920-1925 by Amédée Ozenfant and Le Corbusier, was an example of a successful avant-garde strategy which let both editors, marginal in the field of art, achieve the status of “leaders” of the modernist movement, recognized or at least carefully watched by artists and critics abroad. Next to other factors, important was the visual aspect of the magazine, praised for many impressive, modern illustrations, often reproduced in other avant-garde publications. The author analyzes visual resources used and reproduced in L’Esprit Nouveau, referring to the postulates of “objectivism” and “thingness”, endorsed by the periodical, and considering the part that “ready-made” images, found in the daily press and commercial catalogues as well as on postcards. played in Le Corbusier’s polemical and programmatic texts. Their strongly persuasive message was often rooted in montage and quotations which stressed its heterogeneity. In terms of composition and aesthetics, the reproduced images supported the aesthetics of transparency, order, and thingness, so characteristic of L’Esprit Nouveau. The emblems of modernity emerged from the movement of anonymous images which acquired the value of symbols.   Ozenfant’s and Le Corbusier’s use of images borrowed from popular culture, as well as from albums and art books, makes one consider not only their rhetorical effectiveness, but also their role in the creative process and thinking. In Le Corbusier’s artistic practice, those easily available, miniaturized images were a common instrument enhancing his visual, aesthetic approach. Such an approach, according to Georg Simmel, seems to be characteristic of the modernist attitude to the material world that consisted in subjective distance combined with the apparently opposite desire to “go back to things” by making them more concrete and closer to the senses.

A Gruta do Sumidouro está localizada no município de Campo Formoso (BA), a aproximadamente 500 km de Salvador, capital do Estado. A região faz parte de um conjunto de grutas representadas por três pontes calcárias que cortam o Rio Pacuí, constituindo-se vestígios de uma grande caverna por onde esse rio corria subterraneamente no passado. Com extensão de aproximadamente 500 m, a Gruta possui diversas formações carbonáticas, tais como, estalactites, estalagmites, travertinos, colunas, além de figuras rupestres. Devido ao desconhecimento ou mesmo negligência por parte da população, na maioria das vezes, as pessoas fazem mau uso do espaço, gerando assim impactos ambientais negativos que podem ser irreversíveis. Nesse sentido, o presente trabalho tem como escopo principal a identificação dos diversos tipos de impactos causados a partir da visitação/turismo na Gruta do Sumidouro (Pontes do Sumidouro), objetivando correlacionar tais impactos às atividades antrópicas, e a partir disso, sugerir medidas que possam minimizar esses impactos na caverna estudada, contribuindo assim para uma melhor conservação do local. O método usado para coleta dos dados foi um estudo de caráter qualitativo, em que foram realizadas visitas técnicas in loco, e também feitos registros fotográficos das diversas formas de impacto. Os resultados da pesquisa apontam que de fato a população causa impacto negativo à caverna, uma vez que foram encontrados diversos fatores negativos, como lixo, pichação nas paredes, entre outros. Ao final deste trabalho são sugeridas algumas medidas para mitigar o impacto das visitações na Gruta, tentando se aproximar ao máximo do que chamamos de turismo responsável.

Objetivou-se nesse estudo conhecer a diversidade florística e a fitossociologia em uma área de ecótono Cerrado-Caatinga no Sul do Piauí. Para amostragem do componente arbóreo foram alocadas aleatoriamente 20 parcelas de 400 m2 (20 × 20 m). Nas parcelas foram mensurados todos os indivíduos vivos com circunferência à altura do peito (CAP) ≥ 6 cm. Avaliou-se os parâmetros fitossociológicos da estrutura horizontal e a diversidade florística das espécies através do índice de diversidade de Shannon (H’). Foram amostrados 2.080 indivíduos distribuídos em 43 espécies e 15 famílias. O índice de diversidade (H’) encontrado foi de 2,77 nats.ind-1. As famílias mais representativas em número de espécies foram Fabaceae (19), Myrtaceae (3) e Combretaceae (3). As espécies mais representativas foram Combretum anfractuosum, Cenostigma macrophyllun, Terminalia actinophylla, Brosimum longifolium e Hymenaea eriogyne que juntas representaram 54,71% dos indivíduos. A distribuição diamétrica mostrou que a maioria dos indivíduos se encontram nas menores classes diamétricas, o padrão J invertido é um indicativo de que as espécies estão se regenerando. Todas as espécies, independente do seu tamanho populacional, contribuem para a diversidade e desenvolvimento da comunidade. O número de indivíduos e a diversidade de espécies mostram que o fragmento se encontra em bom estado de conservação.
Impactos da exótica invasora Boerhavia diffusa L. sobre a diversidade de espécies do estrato herbáceo e arbustivo autóctone de uma área ripária na Caatinga, Sergipe, Brasil

Nosso objetivo foi estudar os impactos causados pela espécie exótica invasora Boerhavia diffusa sobre o estrato herbáceo e arbustivo em uma área ripária de Caatinga em Canindé de São Francisco, SE. Para isso, utilizamos o método de parcelas e amostramos dois ambientes nos quais todas as espécies herbáceas foram contabilizadas e estimados os parâmetros estruturais das comunidades. Amostramos 13 espécies e 513 indivíduos no ambiente invadido e 36 espécies e 1.056 indivíduos no ambiente não invadido. A diversidade de espécies baseada no índice de Shannon-Wiener (H’) foi de 1,69 para o ambiente invadido e de 2,63 para o ambiente não invadido. Nossos resultados sugerem que Boerhavia diffusa afeta de maneira negativa a diversidade de espécies do estrato herbáceo e arbustivo autóctone da área estudada.

The first case of primary hypertrophic osteoarthropathy with soft tissue giant tumors caused by HPGD loss-of-function mutation

Background

Primary hypertrophic osteoarthropathy (PHO) is a rare genetic multi-organic disease characterized by digital clubbing, periostosis and pachydermia. Two genes, HPGD and SLCO2A1, which encodes 15-hydroxyprostaglandin dehydrogenase (15-PGDH) and prostaglandin transporter (PGT), respectively, have been reported to be related to PHO. Deficiency of aforementioned two genes leads to failure of prostaglandin E2 (PGE2) degradation and thereby elevated levels of PGE2. PGE2 plays an important role in tumorigenesis. Studies revealed a tumor suppressor activity of 15-PGDH in tumors, such as lung, bladder and breast cancers. However, to date, no HPGD-mutated PHO patients presenting concomitant tumor has been documented. In the present study, we reported the first case of HPGD-mutated PHO patient with soft tissue giant tumors at lower legs and evaluated the efficacy of selective COX-2 inhibitor (etoricoxib) treatment in the patient.

Methods

In this study, we summarized the clinical data, collected the serum and urine samples for biochemical test and analyzed the HPGD gene in our patient.

Results

A common HPGD mutation c.310_311delCT was identified in the patient. In addition to typical clinical features (digital clubbing, periostosis and pachydermia), the patient demonstrated a new clinical manifestation, a giant soft tissue tumor on the left lower leg which has not been reported in HPGD-mutated PHO patient before. After 6-month treatment with etoricoxib, the patient showed decreased PGE2 levels and improved PHO-related symptoms. Though the soft tissue tumor persisted, it seemed to be controlled under the etoricoxib treatment.

Conclusion

This finding expanded the clinical spectrum of PHO and provided unique insights into the HPGD-mutated PHO.
Elevated serum neuregulin 4 levels in patients with hyperthyroidism

Objective

Recent studies have shown that neuregulin 4 (Nrg4), a member of the epidermal growth factor (EGF) family of extracellular ligands, plays an important role in the prevention of obesity, insulin resistance and nonalcoholic fatty liver disease (NAFLD). Considering that thyroid hormone (TH) has profound effects on whole-body energy metabolism, we speculate that circulating Nrg4 levels might be altered in patients with hyperthyroidism.

Design and methods

A total of 129 hyperthyroid patients and 100 healthy subjects were recruited. Of them, 39 hyperthyroid patients received thionamide treatment for 3 months until euthyroidism. Serum Nrg4 levels were determined using the ELISA method. To further confirm the relationship between TH and Nrg4, C57BL/6 mice were treated with T3 and quantitative real-time PCR was performed to detect Nrg4 gene expression.

Results

Serum Nrg4 levels were significantly elevated in hyperthyroid patients as compared with normal controls (3.84 ± 1.63 vs 2.21 ± 1.04 ng/mL, P < 0.001). After achieving euthyroidism by thionamide treatment, serum Nrg4 levels dropped markedly from 3.57 ± 1.26 to 1.94 ± 0.72 ng/ml (P < 0.001). After adjustment for potential confounders, serum Nrg4 levels were independently associated with hyperthyroidism. The upregulation of Nrg4 expression in the livers and white adipose tissues by T3 was further confirmed by animal and cell culture experiments.

Conclusions

Serum Nrg4 levels were increased in patients with hyperthyroidism. The liver and white adipose tissue might be primary sources contributing to elevated serum Nrg4 concentrations.
