Effects and safety of metformin in patients with concurrent diabetes mellitus and chronic obstructive pulmonary disease: a systematic review and meta-analysis
Authors: Liang Ziting , Yang Mengge , Xu Changjuan , Zeng Rong , Dong Liang
Published: July 2022

Aim

This study aimed to investigate the effects and safety of metformin in patients with concurrent diabetes mellitus (DM) and chronic obstructive pulmonary disease (COPD).

Methods

PubMed, Embase, Web of Science, the China National Knowledge, and Cochrane Database were searched to find studies that examined the effects and safety of metformin in patients with concurrent DM and COPD. We conducted a meta-analysis with a risk ratio (RR) and assessed the quality of included studies and pooled evidence.

Results

Eight studies were involved. Metformin was associated with lower risk of COPD-related hospitalizations (RR: 0.72, 95% CI: 0.53–0.98; I2= 89%) and all-cause mortality (RR: 0.60, 95% CI: 0.36–1.01, I2= 69%) in patients with concurrent DM and COPD, but did not increase the risk of hyperlactatemia (RR: 1.14, 95% CI: 0.92–1.41, I2 = 8%).

Conclusions

Metformin use is associated with lower risk of COPD-related hospitalizations and risk of all-cause mortality without increasing the risk of hyperlactatemia. Considerations should be given to conduct more high-quality randomized trials involving larger samples.
Matrix metalloproteinase-induced cervical extracellular matrix remodelling in pregnancy and cervical cancer
Authors: Amabebe Emmanuel , Ogidi Henry , Anumba Dilly O
Published: July 2022

Graphical abstract

The phenomenal extracellular matrix (ECM) remodelling of the cervix that precedes the myometrial contraction of labour at term or preterm appears to share some common mechanisms with the occurrence, growth, invasion and metastasis of cervical carcinoma. Matrix metalloproteinases (MMPs) are zinc-dependent endopeptidases that are pivotal to the complex extracellular tissue modulation that includes degradation, remodelling and exchange of ECM components, which contribute to homeostasis under normal physiological conditions such as cervical remodelling during pregnancy and puerperium. However, in cancer such as that of the uterine cervix, this extensive network of extracellular tissue modulation is altered leading to disrupted cell–cell and cell–basement membrane adhesion, abnormal tissue growth, neovascularization and metastasis that disrupt homeostasis. Cervical ECM remodelling during pregnancy and puerperium could be a physiological albeit benign neoplasm. In this review, we examined the pathophysiologic differences and similarities in the role of MMPs in cervical remodelling and cervical carcinoma.

Lay summary

During pregnancy and childbirth, the cervix, which is the barrel-shaped lower portion of the womb that connects to the vagina, gradually softens, shortens and opens to allow birth of the baby. This process requires structural and biochemical changes in the cervix that are stimulated by enzymes known as matrix metalloproteinases. Interestingly, these enzymes also affect the structural and biochemical framework of the cervix during cervical cancer, although cervical cancers usually occur after infection by human papillomavirus. This review is intended to identify and explain the similarities and differences between the structural and chemical changes in the cervix during pregnancy and childbirth and the changes seen in cervical cancer.
An Integrative Review on Dining Experiences of Vegetarians as a Minority Food Culture: Based on Qualitative Research
Authors: Park Min Kyung , Kim Jasmyn , Kim Sanghee
Published: July 2022

Background: Despite the emphasis on the health benefits of a vegetarian diet and growing interest in the contribution of meat consumption to climate change and the resulting health hazards, few studies have been conducted to understand the vegetarian dining experience. The purpose of this study was to analyze characteristics of qualitative research on dining experiences for vegetarians, and to suggest development directions for understanding and coping with it.Methods: An integrative review method was used. Based on Whittemore & Knafl’s approach, five steps were applied.Results: Of the 413 articles initially retrieved from the electronic databases, 12 studies met the selection criteria. Three characteristics related to the dining experiences of vegetarians were derived: (1) feeling healthy, (2) establishing identity, and (3) transition to healthy diet. Results emphasize that many of the difficulties that vegetarians face in maintaining a vegetarian diet are due to relationships with non-vegetarians, and vegetarians use various negotiation strategies to positively interact with non-vegetarians.Conclusions: This review found that for vegetarians, a vegetarian diet is a lifestyle that reflects their identity and is an important transition for a healthier life. As a minority in the food culture, there is a need to promote the transition to a healthy dining experience by understanding what the dining experience of vegetarians is like and considering alternatives to the difficulties they face.

Authors: Jeong Yeon Son , Park Jeong Yun
Published: July 2022

Background: The purpose of this study was to investigate the levels of attitude and practice regarding sexual health care in patients with cancer among nurses.Methods: This study used a cross-sectional descriptive design. Participants were 152 nurses who care patients with cancer at a general hospital in Gangwon province. Data were collected from November 7 to 10, 2016 using self-report questionnaire including each 17 item of sexual health care scale-practice and attitude.Results: The subjects’ average age was 29.8±6.3 years, and oncology nursing experience was 7.3±6.2 years. Nurses’ attitude was the average score of 26.6 out of 51. Practice was 2.63 out of 21. Formal education about sexual health care (t=2.01, P=0.048) had significant influenced on nurses’ attitude and age (F=4.45, P=0.013) and working site (F=3.28, P=0.013) on nurses’ practice. The relationship between nurses´attitude and practice toward cancer patients´ sexual health nursing was statistically significant (r=0.33, P=0.001).Conclusions: The findings of this study indicate that it is imminent for nurses to acquire various information about sexual problems with patients during cancer treatment. Educational programs for sexual health care for nurses need to be developed to provide cancer patients to improve their sexual health.
Emerging Concepts in Congenital Cytomegalovirus
Authors: Pesch Megan H. , Schleiss Mark R.
Published: July 2022

Over a century of research has focused on improving our understanding of congenital cytomegalovirus (cCMV), yet it remains the most common congenital infection in the United States, affecting 3 to 6 per 1000 live born infants each year. Pregnancies affected by cCMV are at a heightened risk of spontaneous abortion and intrauterine fetal demise. Neonates born with cCMV are also at substantial risk for long-term neurodevelopmental sequelae and disability, including sensorineural hearing loss, even those born without clinically apparent disease. Considerable progress has been made in recent years in study of the epidemiology and transmission of cCMV, developing better diagnostic strategies, implementing newborn screening programs, improving therapeutics, and launching vaccine trials. In this article, we review recent developments in the understanding of the virology and immunobiology of cytomegalovirus. We further discuss how this knowledge informs our understanding of the pathophysiology of cCMV and directs strategies aimed at improving outcomes and quality of life for congenitally infected children. We also provide an update on the epidemiology of cCMV in the United States, evolving scientific understanding of maternal-fetal transmission, enhanced screening approaches, and recognition of neonatal and long-term sequelae. Finally, we review the current landscape of pediatric cCMV research and provide recommendations for novel and high-priority areas for future investigation.
‘Ted Cruz cucks again’
Authors: Kosse Maureen
Published: July 2022

This article provides a multimodal semiotic analysis of the word cuck as used in online white supremacist spaces. A fundamental belief of the white supremacist ‘alt-right’ movement is an anti-Semitic narrative that positions Jewish people as a ‘global elite’ that seeks to oppress and eliminate white populations. Central to this belief is that Jewish people actively manipulate populations of colour, Black people in particular, to overtake white populations in a process known as ‘white genocide’ or ‘the great replacement’. Based on a digital ethnography of alt-right communities on Voat, Twitter and Reddit, this article demonstrates how the memeified word ‘cuck’, a pejorative term for ‘weak’ men on the US political right wing, draws from and reproduces this white nationalist conspiracy theory through allusions to interracial cuckold pornography. While disguised as innocuous, expressions like ‘cuck’ provide insight into how the alt-right weaponises misogynist and racist humour in its radicalisation efforts.

ABSTRACT: In some situations, the neonatal mortality rate in dogs can be high, and perinatal and postnatal veterinary care is essential to improve survival. This study to compared the Apgar score, serum lactate levels, and blood gas analysis results in 30 neonates born by elective cesarean section (GCE, n = 18) or cesarean section due to dystocia (GD, n = 12). Neonates were assessed at five time points: T0, at birth; T1, 3 h after birth; T2, 6 h after birth; T3, 12 h after birth; and T4, 24 h after birth. At T0, in the GCE group, 55.6% of the animals presented with adequate vitality, while 38.8% showed moderate changes in the Apgar score. In the GD group, 83.3% of the neonates had severe loss of vitality. At T1, none of the GCE neonates and 8.3% of the GD neonates presented with vitality deficits. Hyperlactatemia was observed in 83.3% of the GD neonates, and mixed acidosis (metabolic and respiratory) was observed at T0 in most neonates in both groups (GCE, 55.6%; GD, 72.7%). Compared to GCE neonates, the acid-base disorders were more severe and their recovery slower in GD neonates. At T0, GD neonates had higher hyperlactatemia and a lower Apgar score (worse vitality) than those of GCE neonates.

Published: July 2022

Resumo Objetiva-se mapear jogos educativos relacionados à sexualidade de adolescentes/jovens, a partir de publicações ocorridas na última década (2011 a 2020). Realizou-se uma revisão integrativa nas bases de dados Web of Science, SCOPUS, MEDLINE/PubMed e LILACS em setembro de 2020, com a inclusão final de 16 estudos. Identificaram-se jogos desenvolvidos em quatro continentes, com predominância em países de renda alta, sendo os Estados Unidos e o Brasil os que mais publicaram. As ferramentas eram, em sua maioria, videogames e jogos digitais, com a adoção de cenários e enredos simulados. Sobre o desenvolvimento, houve preferência pelo modo de construção participativo; alguns também passaram por processo de validação. Abordavam diversas áreas da sexualidade humana e demonstravam potencial positivo para uso, com ganhos educacionais e mudança de hábitos, mas seus resultados precisam ser ponderados. Apenas três jogos tiveram seus efeitos avaliados por estudos controlados e randomizados.
Disputas epistemológicas na associação causal entre Zika vírus e síndrome congênita: uma análise de controvérsia
Authors: Oliveira Monique Batista de , Akerman Marco
Published: July 2022

Resumo Um aumento de más-formações em crianças em 2015 no Brasil é associado ao vírus Zika que circulara meses antes, deixando disputas que ainda possui ecos. Usando elementos de um campo das ciências sociais que se dedica ao mapeamento de controvérsias científicas, este trabalho realizou 15 entrevistas semiestruturadas com pesquisadores e gestores envolvidos na associação causal. Investigou-se como esses atores observam o papel de condicionantes sociais no desfecho da Síndrome Congênita por Vírus Zika (SCZ) e os caminhos trilhados para mitigá-los após a epidemia. Há uma preocupação de todos com variáveis sociais e sua relevância no desfecho da SCZ, com uma decepção generalizada sobre o encaminhamento dessas questões após o pico de casos, mas esses fatores não entraram em uma narrativa mais central sobre a causalidade. Nota-se também disputas epistêmicas sobre esse desfecho. Uns atrelam à responsabilidade ao poder público ou se resignam com o resultado; outros cobram posturas ativas de pesquisadores que participaram de centros do poder, com divergências sobre o posicionamento da ciência. O artigo pontua a necessidade de ciências reflexivas que atentem para sua agência no mundo, bem como para articulações de narrativas interdisciplinares e multicausais para crises de saúde pública no Brasil.

Published: July 2022

Abstract The aim of this study was to spatially examine the distribution of establishments for the acquisition of food that is ready to consume around the Health Academy Program (PAS) in Belo Horizonte, Minas Gerais, Brazil, according to the Municipal Human Development Index (IDH-M).This is an ecological study with the PAS as the unit of analysis. The establishments contained in a circular buffer with a radius of 900 meters from the 77 units of the PAS in operation were evaluated. Address and type of establishment data were obtained from a public list and verified in a virtual audit. Thematic kernel maps were used. A total of 3,050 establishments were identified around the PAS units. Higher densities were observed around units located in the city’s south-central region and in areas with high and very high IDH-M. There was a high density of establishments selling ready-to-consume foods around the PAS units, especially in the wealthier parts of the city. These results are useful in supporting the planning of actions aimed at strengthening the PAS as a promoter of healthy eating environments. Further, it reinforces the need for equitable public policies for supply and regulation, aiming to promote access to adequate and healthy food for all.

Published: July 2022

Abstract The COVID-19 pandemic has highlighted the economic, social, and oral care health inequities in societies, especially in the developing world. Severe restrictions have been imposed on dental practices, limiting prophylactic and routine oral care health, allowing treatment only for emergencies. Since dental care includes procedures that generate aerosols, the risk of infection for dental personnel has increased significantly. In this review, a comprehensive and updated source of information about SARS-CoV-2/COVID-19 and the impacts it is having on oral health care is presented. The ongoing repercussions in dental practice and in dental education, including the opportunities for practice innovation that are evolving, are also indicated. Also, a discussion of the psychosocial factors that affect health and the quality of life of an individual, such as stress, depression, and anxiety, is provided. This pandemic may be an opportunity to promote the inclusion of well-established prevention measures, together with the use of teledentistry in academic dental curricula, encourage the implementation of new perspectives for the effective instruction and interactions with students, and foster the transition toward e-learning strategies in dental education.

Published: July 2022

Abstract The physical, mental and social well being, refers to a new concept of health, far from a conceptualisations of absence of disease Additional challenges emerge as individuals face deep social inequities depending on their ethnicity, rural residence or low educational level, as these translate to poor access to health services and more difficulties to adhere to healthy living behaviors. The objective of this study was to assess the perception that adolescents and young adults in Latinamerica have of the importance of healthy living behaviors (HLB) in the physical, emotional and lifestyle spheres. The approach is considered quantitative and descriptive with a cross sectional design. The sampling consisted of 192 young adults in Brazil, Colombia and Mexico. The results show that participants prioritize higher emotional wellbeing. They state that the health crisis changed the perception, as now the value more the emotional side of health, and understand the status of a combination of the different aspects of wellness. The Latinamerican context poses a challenge in designing strategies with a holistic health perspective, with complexities in the economic and sociocultural domains.

Published: July 2022

Resumo A abordagem de Saúde do Trabalhador entende que é necessário ampliar o objeto das políticas públicas para transformar os processos de trabalho que determinam a relação saúde-doença. Essa ampliação traz desafios que impulsionam o desenvolvimento da formulação e implementação das políticas para a vigilância e prevenção de agravos. O objetivo deste artigo é analisar o desenvolvimento das políticas brasileiras em saúde do trabalhador a partir das contradições históricas. Para este fim, foi usado o conceito analítico de contradição da teoria da atividade histórico-cultural. Trata-se de uma revisão de escopo que inclui 64 estudos teóricos, empíricos e literatura cinza publicados entre 1991 e 2019. Os resultados da análise mostraram que: a partir da mudança de objeto da prevenção inserida pela abordagem da Saúde do Trabalhador, emergiram cinco novas contradições que estão relacionadas ao predomínio de instrumentos do modelo de atividade anterior, instrumentos normativos e de formação, divisão do trabalho para as ações de assistência e vigilância, articulações intra e intersetoriais e controle social. Essas contradições permitiram impulsionar algumas mudanças, mas também existem limitações que persistem em torno de um objeto desafiante.

Authors: Pinto Luiz Felipe , Caldas Ana Luiza Ferreira Rodrigues
Published: July 2022

Abstract The IBGE has been playing a leading role in the public policy evaluation in Brazil since 2019. After the National Health Survey (PNS) evaluated primary care services in the Unified Health System (SUS) provided to adults, in 2022, the Continuous National Household Sample Survey (PNAD-C) investigated child health. To this end, it adopted one version of the Primary Care Assessment Tool (PCAT), developed and disseminated by Starfield and Shi to assess the existence and extent of the attributes of PHC services. The target audience surveyed included children under 13 years of age, and the questionnaires were answered by their guardians/caregivers. It included all the 27 federative units of the country in random probabilistic samples, also unfolding in the Brazilian metropolitan regions and capitals. This is the largest household survey on child health assessment ever conducted in Brazil. With the PNS-2019 and the PNAD-C in 2022, IBGE inaugurates its greatest legacy for Brazilian primary health care regarding the evaluation of SUS users, with all federative units recognizing and understanding how Brazilian society evaluates health services at the first level of care.

Published: July 2022

Abstract The influence of abiotic factors on the abundance of microorganism populations in soil has been sparsely studied, especially regarding Bacillus thuringiensis (Bt) bacteria. Therefore, this research was aimed at analyzing the relationship between the chemical and textural characteristics of the soil of the Cerrado (savanna) of Maranhão State on the abundance of Bacillus thuringiensis. Soil samples were collected in different municipalities in eastern Maranhão: São Mateus do Maranhão, Alto Alegre, Coroatá, Timbiras and Codó. The soil samples were obtained in the 0-0.1 m layer for soil fertility and texture analysis. Then, in the same area for the isolation of Bt, 1 g of soil was collected. The colonies obtained in the isolation that featured morphological characteristics of Bacillus spp. were visualized under phase contrast microscopy. Principal component analysis, clustering and correlations were peformed. Results: The sand content correlated positively with the Bacillus thuringiensis index (iBt). The cluster analysis allowed for verifying that the soils not showed iBt in function of high concentrations of aluminum (Al) and potential acidity (H+Al). Considering as these attributes (Al and H+Al) alter the availability of P in the soil, the abundance of Bacillus thuringiensis may have been impaired by the deficiency of this element in the environment. Conclusion: Bt has correlations with soil texture, and high concentrations of aluminum and potential acidity in the soil influencing the permanence of Bacillus thuringiensis in Maranhão eastern Cerrado.

Authors: Rosa Arthur A. S. , Forti Cristiano A. B. , Dias Vitor F. M. B.
Published: July 2022

ABSTRACT Purpose: This study aims to analyze the effects of crisis periods on the relationship between internationalization and the working capital requirement (WCR), from 2010 to 2018, using publicly-traded Brazilian firms as a sample. Originality/value: This paper contributes to the literature by addressing a topic that is still little explored regarding the relationship between WCR and internationalization, as well as analyzing the influence of the economic crisis on this relationship, using, for that, three internationalization proxies for the robustness of the results. Design/methodology/approach: To achieve this goal, a regression by the generalized method of moments (GMM) with panel data was used. For this, three databases were used for data collection: Economatica, Securities and Exchange Commission (Comissão de Valores Mobiliários – CVM), and J. P. Morgan. Findings: More internationalized Brazilian firms tend to have a higher WCR and use stock as a way to protect themselves against possible unforeseen events arising from import processes. In addition, internationalization is shown as a way for firms to maintain their level of activity during national crisis periods.

Published: July 2022

Neste trabalho descrevemos um formalismo para descrever a Mecânica Clássica fracionária segundo o cálculo fracionário conformável. Assim, uma breve revisão sobre cálculo diferencial e integral conformável foi feita. Na sequência, as versões conformáveis dos formalismos Lagrangiano e Hamiltoniano são apresentadas. Como exemplo, o oscilador harmônico conformável e a equação de onda conformável são discutidos. Em todas as situações consideradas, os resultados usuais são obtidos se a ordem da derivada ( α) for igual a 1. Um resultado interessante é que se considerarmos 1 - α ≪ 1, o oscilador harmônico conformável torna-se análogo aos oscilador usual com massa variável e termo de dissipação.

A análise se deu de maneira anônima, a partir das ferramentas disponíveis pelo aplicativo, pensando a montagem dos corpos-perfis e indicou que marcadores sociais acabam por engendrar processos de individualização disciplinar e totalização biopolítica. Aderir a planos com custos maiores abrem novos e ampliados usos de ferramentas e funções, propiciando mais poder de filtragem e monitoramento na busca e interação com perfis. Conclui-se que o Grindr conduz à produção de subjetividades marcadas, por certa estética e saúde, e viabiliza uma paradoxal sociabilidade privatizada/privatizante em tempos neoliberais.

Resumo Este artigo analisa o poema “Farol da Barra” tendo como base a teoria de experiência estética de Jauss (1994). Também trazemos para a discussão as propostas teóricas de Figurelli (1988), Zilberman (1989), entre outros. A partir de um método de análise qualitativa, com a finalidade de legitimar a produção literária de e para pessoas surdas, propomos uma analogia entre as ideias defendidas pela estética da recepção, mormente partindo das propostas de Jauss, e as ideias evidenciadas pelo poema surdo “Farol da Barra”, criado por, Maurício Barreto, poeta surdo de Salvador/BA. Nesse sentido, concluímos que, assim como a literatura de não surdos, a literatura surda pode ser analisada e percebida conceitualmente pelo observador (leitor), além de possibilitar ao autor surdo construir fruição estética inerente à poesia em língua brasileira de sinais (Libras), de acordo com as três concepções de experiências fundamentais de Jauss (1994), que são poiesis, aisthesis e katharsis.
À terceira margem do Atlântico: um sertão de silêncio e desejo em Desmedida, de Ruy Duarte de Carvalho
Authors: Fonseca Cíntia Borges A.
Published: July 2022

Resumo Tomando Desmedida como bússola e o percurso do lusoangolano Ruy Duarte de Carvalho como rota, o presente artigo discute e problematiza a busca de uma origem e de um sentido para o sertão na produção simbólica nacional. Desde os relatos dos primeiros viajantes que chegaram ao país, passando por textos de pesquisadores, historiadores ou escritores, o sertão é descrito como uma imensidão vazia a ser desbravada e contornada por palavras - palco para múltiplas figurações, transgressões e subversões da linguagem. Desmedida funciona como disparador de sentido e fio condutor para o percurso empreendido neste trabalho: aquele que aponta para o sertão como um excesso de vazio - ou falta de medida, de limite e de fronteira - já na estrutura dos significantes selecionados para nomeá-lo. Ao atravessar as obras de Euclides da Cunha e de Guimarães Rosa, Ruy Duarte de Carvalho apresenta dois modos distintos de lidar com o real do sertão e com a impossibilidade de o narrar. A torção de textos, tempos e existências empreendida por Carvalho é lida a partir da virada dos modos de subjetivação do sujeito e da linguagem e seus efeitos sobre os conceitos de ficção e representação na chegada à modernidade, tais quais identificados pelo filósofo Jacques Rancière. Para investigar os conceitos de real e de vazio, foram utilizados como referenciais teóricos artigos de Raul Antelo e de Jacques Lacan.

Abstract: During embryogenesis and seed filling, developing seeds are metabolically highly active, while at the desiccation stage of tolerant seeds a decreased metabolism is expected. Seeds of Poincianella pluviosa present an extensive maturation cycle (11 months), longer than seed storability at room temperature (8 months). The metabolic profile of these seeds was characterized during maturation and drying, focusing in their role on seed behavior after shedding. Distinct responses of the embryonic axes and cotyledons to drying were observed depending on the developmental stage. Low proportions of tricarboxylic acids intermediaries until maturity indicated a low respiratory metabolism prior to the desiccation stage. Changes in shikimate, 4-coumarate, and quinate proportions suggest a metabolic shift towards the synthesis of chlorogenate isomers, found in high proportions in dispersed seeds. High proportions of lactate and glycerol were observed in immature seeds after artificial drying, but also in naturally dried axes of dispersed seeds. This suggests an active metabolism prior to drying and an osmotic stress under hypoxia, mechanisms that were never described before in desiccation-tolerant seeds. The results indicated that P. pluviosa seeds are dispersed with an incomplete metabolic switch-off, which can be related to their short lifespan.

ABSTRACT Purpose To investigate the immediate effect of voiced tongue vibration (VSL), high-resistance straw in the air (CAR), and overarticulation (OA) on the vocal space of vocally healthy women (MVS) and with vocal nodules (MNV). Methods 12 women participated in the MNV and 12 women in the MVS, allocated to perform the vocal exercises of VSL, CAR, and OA. Each participant performed only one of the three proposed exercises, for 5 minutes, preceded and followed by recording a sequence of vehicle sentences for extracting formants (F1 and F2) from the vowel segments [a, i, u]. The vowel space was analyzed through the differences between the measures of the formants of the vowels. Results we observed a reduction of F1 in the interval [a]-[i] and [i]-[u] and of F2 between the vowels [a]-[u] and [i]-[u] in the MVS, after performing the CAR. In MNV, we observed a reduction of F2 in the interval [a]-[i] after VSL. In the intergroup analysis, there were higher F1 values between the intervals of the vowels [a]-[i] and [i]-[u] in the MVS, before performing the CAR, and after exercise only in the interval [a]-[i]. A higher value of F1 and F2 was observed in the interval between the vowels [i]-[u] in the MNV after VSL. Conclusion The VSL exercise reduced the vowel space in MNV women. CAR reduced the vocal space of women in the MVS. The MNV had a smaller vowel space compared to the MVS before and after the CAR. We observed a reduction in the vowel space in the MNV compared to the MNV after the VSL exercise.
Recursion in Abstract Argumentation is Hard --- On the Complexity of Semantics Based on Weak Admissibility
Authors: Dvořák Wolfgang , Ulbricht Markus , Woltran Stefan
Published: July 2022

We study the computational complexity of abstract argumentation semantics based on  weak admissibility, a recently introduced concept to deal with arguments of self-defeating  nature. Our results reveal that semantics based on weak admissibility are of much higher  complexity (under typical assumptions) compared to all argumentation semantics which  have been analysed in terms of complexity so far. In fact, we show PSPACE-completeness  of all non-trivial standard decision problems for weak-admissible based semantics. We then  investigate potential tractable fragments and show that restricting the frameworks under  consideration to certain graph-classes significantly reduces the complexity. We also show  that weak-admissibility based extensions can be computed by dividing the given graph into  its strongly connected components (SCCs). This technique ensures that the bottleneck  when computing extensions is the size of the largest SCC instead of the size of the graph  itself and therefore contributes to the search for fixed-parameter tractable implementations  for reasoning with weak admissibility.

Not All Quiet on the Culinary Front: The Battle Over Borshch in Ukraine
Authors: Lesiv Mariya
Published: July 2022

Borshch (also spelled as borscht and borsch) has lately become heavily contested as the intangible heritage of both Ukraine and Russia. Media reports trace the roots of the dispute to a 2019 tweet by the Russian Foreign Ministry describing the soup as part of Russia’s significant heritage. In response, Ukrainian cultural activists have moved the traditional beet soup from intimate vernacular settings into the political spotlight. Borshch contests, workshops, and festivals are now organized in Ukraine at the highest state levels involving top-ranking politicians and activists—all meant to legitimize borshch as a Ukrainian, not Russian, dish. This paper focuses on the complex political trajectories of borshch in Ukraine. I show that the fight over the ownership of the dish, while it may appear humorous to outsiders, communicates “unlaughter” [Billig 2005] to those who reside in close geographical and emotional proximity to the real problems that the dispute communicates. This seemingly innocent dish has come to symbolize the serious matter of resistance to external threats in the context of the ongoing Ukraine-Russia crisis, simultaneously serving as a unifying tool within Ukraine. In other words, external gastroanimosity shaped by the crisis is directly related to the efforts of internal “gastrodiplomacy” [Ruddy 2014]. Additionally, unlike many other forms of traditional culture discussed in resistance and protest-related literature, borshch in Ukraine follows a cyclical trajectory. A dish that found its way from intimate family tables to the large international

Purpose: To evaluate the risk factors associated with 30-day mortality in patients with postoperative acute kidney injury who underwent continuous renal replacement therapy (CRRT).Methods: Retrospective analysis of the medical charts of patients with postoperative acute kidney injury who underwent CRRT in the intensive care unit between April 2012 and May 2019 was conducted.Results: There were 71 patients whose average age was 64.8 years, and average Acute Physiology and Chronic Health Evaluation 2 score was 26.2. There were 37 patients who had non-trauma emergency surgery, 16 who required trauma surgery, and 18 who had elective major surgery. In most patients, CRRT was started based on Stage 3 Acute Kidney Injury Network criteria, and the mean creatinine level at the time of CRRT initiation (3.62 mg/dL). The median period from surgery to CRRT was 3 days, and the median CRRT application was 4 days. Forty-seven patients died within 30 days of receiving CRRT. Age, elective major surgery, creatinine level on initiation of CRRT, use of norepinephrine upon the initiation of CRRT, and average daily fluid balance/body weight for 3 days following the initiation of CRRT were associated with increasing 30-day mortality in univariate analysis. In multivariate analysis, age, major elective surgery, and norepinephrine use upon initiation of CRRT were identified as independent risk factors for 30-day mortality.Conclusion: Surgical patients who underwent CRRT postoperatively had a poor prognosis. The risk of death in elderly patients who have undergone major elective surgery, or are receiving norepinephrine upon initiation of CRRT should be considered.
