Quantitative Microbial Risk Assessment (QMRA) of Workers Exposure to Bioaerosols at MSW Open Dumpsites
Authors: Akpeimeh G. F. , Fletcher L. A. , Evans B. E. , Ibanga I. E. 
Published: January 2021

AbstractThe bioaerosol exposure data from the study by Akpeimeh, Fletcher, and Evans (2019) was used to compute the risk of infection from the exposure of dumpsite workers to Aspergillus fumigatus and Escherichia coli O157:H7. A stochastic (Markov Chain) model was used to model the transport of the inhaled dose though the human respiratory system and then integrated into the beta‐Poisson dose–response model to estimate workers risks of respiratory and gastrointestinal (GI) infection. The infection risk was computed based on workers exposure to E. coli O157:H7 at 10–50% pathogen ingestion rate and pathogen‐indicator ratio (P:I) of 1:103 and 1:104, while exposure to A. fumigatus was based solely on the average initial exposure dose. The results showed that after 11 hours of exposure, workers engaged in scavenging, waste sorting, and site monitoring were at risk of respiratory and GI infection in the magnitude of 10−1. However, the risk estimates associated with specific areas of the dumpsite showed that, the risk of GI infection at the active area ranged between 3.23 × 10−3–1.56 × 10−2 and 3.25 × 10−4–1.62 × 10−3; dormant area 2.06 × 10−3–1.01 × 10−2 and 2.09 × 10−4–1.04 × 10−3; entrance 1.85 × 10−3–9.09 × 10−3 and 1.87 × 10−4–9.27 × 10−4; boundary 1.82 × 10−3–8.82 × 10−3 and 2.09 × 10−4–8.94 × 10−4 for P:I = 1:103 and 1:104 respectively, while the risk of respiratory infection risks were in the magnitude of 10−1 for all four locations. The estimated risk of workers developing respiratory and gastrointestinal infections were high for all activities assessed at the dumpsite.
Computed tomography identified mineralisation of the longitudinal odontoid ligament of the horse is associated with age and sex but not with the clinical sign of head shaking
Authors: Talbot Alison M. , Rodrigues Miguel , Maddox Thomas W. 
Published: January 2021

AbstractMineralisation of the longitudinal odontoid ligament has recently been identified in three horses undergoing computed tomographic (CT) examination, but published studies describing the clinical relevance of this finding are currently lacking. The objective of this retrospective, analytical, cross‐sectional study was to investigate the relationship of this image finding to primary presenting complaint, age, breed, use and sex of the patient, and determine any association to the clinical signs of head shaking, neck pain or restricted range of neck motion. Computed tomographic images of 96 horses undergoing examination of the head and cranial cervical spine, for a variety of clinical reasons, were assessed for the presence of mineralisation within the longitudinal odontoid ligament. Clinical records were reviewed; presenting problem, signalment, clinical signs and final diagnoses were recorded and potential associations of presenting primary problem, signalment and individual clinical signs with mineralisation in the longitudinal odontoid ligament investigated, using univariable and multivariable ordinal logistic regression analysis. Final multivariable analysis confirmed significant associations of increasing severity of mineralisation with increasing age (P = .002) and being female (P = .038). There was no association of mineralisation of the longitudinal odontoid ligament with the syndrome of idiopathic head shaking or other clinical signs investigated in this sample of horses. Authors therefore recommend that the clinical significance of mineralisation of the longitudinal odontoid ligament be interpreted cautiously for equine CT studies.
Distinguishing Pathovars from Nonpathovars: Escherichia coli
Authors: Riley Lee W. 
Published: January 2021

ABSTRACTEscherichia coliis one of the most well-adapted and pathogenically versatile bacterial organisms. It causes a variety of human infections, including gastrointestinal illnesses and extraintestinal infections. It is also part of the intestinal commensal flora of humans and other mammals. Groups ofE. colithat cause diarrhea are often described as intestinal pathogenicE. coli(IPEC), while those that cause infections outside of the gut are called extraintestinal pathogenicE. coli(ExPEC). IPEC can cause a variety of diarrheal illnesses as well as extraintestinal syndromes such as hemolytic-uremic syndrome. ExPEC cause urinary tract infections, bloodstream infection, sepsis, and neonatal meningitis. IPEC and ExPEC have thus come to be referred to as pathogenic variants ofE. colior pathovars. While IPEC can be distinguished from commensalE. colibased on their characteristic virulence factors responsible for their associated clinical manifestations, ExPEC cannot be so easily distinguished. IPEC most likely have reservoirs outside of the human intestine but it is unclear if ExPEC represent nothing more than commensalE. colithat breach a sterile barrier to cause extraintestinal infections. This question has become more complicated by the advent of whole genome sequencing (WGS) that has raised a new question about the taxonomic characterization ofE. colibased on traditional clinical microbiologic and phylogenetic methods. This review discusses how molecular epidemiologic approaches have been used to address these questions, and how answers to these questions may contribute to our better understanding of the epidemiology of infections caused byE. coli.*This article is part of a curated collection.
High-Q, High-Rejection Ratio Complex Second-Order Charge-Sampling Switched gm-C Semi-Passive Band-Pass Filter
Authors: Jafari Mohammad Shayan , Jannesari Abumoslem 
Published: January 2021

In this paper, a complex second-order charge-sampling switched [Formula: see text]-[Formula: see text] semi-passive band-pass filter (BPF) is presented which by using the technique of increasing the number of input signal phases without the need to increase the number of clock phases and switches, has been improved out-of-band rejection, near-band rejection and the quality factor of the filter. In addition to the tunable bandwidth and center frequency that can be tuned independently, the proposed filter provides a very high linearity and consumes low power. Designed and simulated in a [Formula: see text]m standard CMOS technology, this filter operating at 1[Formula: see text]GS/s sampling rate has an adjustable center frequency of 11.68–28.5[Formula: see text]MHz and a tunable bandwidth of 1.8–8.74[Formula: see text]MHz. Also, the out-of-band rejection varies from 37[Formula: see text]dB to 39[Formula: see text]dB in an offset frequency of 3 fc. The in-band IIP3, power consumption and input-referred noise are 28[Formula: see text]dBm, 5[Formula: see text]mW and 13.8–18.8[Formula: see text]nv/sqrt (Hz), respectively
Crossing Roads with a Computer-generated Agent

Published: January 2021

This study investigated how people coordinate their decisions and actions with a risky or safe computer-generated agent in a humanoid or non-humanoid form and how this experience influences later behavior when acting alone. In Experiment 1, participants first repeatedly crossed continuous traffic in a virtual environment with a humanoid computer-generated agent (Figure 1). Participants were specifically instructed to cross with an agent that was programmed to be either safe (taking only large gaps) or risky (also taking relatively small gaps). Participants then repeatedly crossed the same roadway alone. We found that participants’ experiences with crossing safe vs. risky gaps with an agent persisted in later trials when the participants crossed alone, such that participants accepted tighter gaps if they were previously paired with a risky than a safe agent. In Experiment 2 (Figure 2), we tested whether experience crossing with a risky or safe non-humanoid object (a floating box) also influenced later behavior when crossing alone. We again found that participants who crossed with the risky object partner took tighter gaps when later crossing alone than those who crossed with the safe object partner. The Discussion focuses on the impact of experiences with virtual agents on perception–action tuning and the potential of using virtual agents for training safe road-crossing behavior.
Design e tipografia como elementos da expressividade da poesia de Augusto de Campos
Authors: Santos Tiago 
Published: January 2021

A poesia de Augusto de Campos afirmou-se concreta ao abandonar as convenções aceitas pelas gerações modernistas imediatamente anteriores. Avançou em prol de uma nova pluralidade de sentidos atingidos pela exploração intensiva do potencial expressivo da palavra e da sua materialidade. É um poeta de invenção, que recuperou a funcionalidade da página, controlando o tempo e o silêncio, que manipulam as sensações através do espaço em branco, e deslocou-se para as galerias e ruas. Neste artigo é analisada a poesia de Augusto de Campos considerando como o texto, na sua forma visual e tipográfica, activa as camadas de significação verbivocovisual e, subsidiariamente, as referências culturais e simbólicas associadas às formas da letra e aos media.
Recepção como elo da obra de arte com o mundo e com a história
Authors: Silva Diogo de Moraes 
Published: January 2021

Baseado na compreensão do artista Marcel Duchamp de que o público conecta a obra artística com o mundo exterior e, ao fazê-lo, contribui para sua incorporação pela história da arte, o presente texto procura delinear a cadeia na qual esse ato de recepção se inscreve. Para isso, recorre a análises provenientes de diferentes campos, a saber, da arte, filosofia, semiologia, sociologia e mediação cultural. Mobilizando os conceitos de “obra aberta”, “coeficiente artístico”, “regime estético”, “distinção” e “mediação documentária”, busca verificar tanto as possibilidades como as limitações de um tipo de encadeamento cuja universalidade é relativizada por incongruências socioculturais e de classe, que fazem com que a influência exercida pelos públicos nos rumos da arte seja marcadamente desigual.
O direito de olhar a partir de Foucault, Spivak e Mbembe
Authors: Beccari Marcos Namba 
Published: January 2021

Este ensaio adota o pensamento foucaultiano como base para propor um recuo teórico em torno da noção de “direito de olhar” enquanto reivindicação de uma posição nas lutas sobre “como ver”. Após contextualizar o certame, reviso dois textos pontuais que cotejam Foucault: Pode o subalterno falar?, de Gayatri Spivak, e Necropolítica, de Mbembe. Do primeiro, depreendo a ideia geral de que o direito de olhar é o contrário do direito de “ver sem ser visto”. Do segundo, deduzo uma função de opacidade e de gestão da invisibilidade que a necropolítica exerce em conjunção com a biopolítica. Por fim, sustento que, se todo “ver” depende de um “não ver”, o direito de olhar reivindica uma posição que está sempre por construir.
O paradigma periódico na arte: a comunidade da escritura
Authors: Alzugaray Paula 
Published: January 2021

O texto parte da natureza comum e contínua entre ensaios de Maurice Blanchot e Jean-Luc Nancy que, a partir da crítica ao fracasso do projeto comunitário do comunismo, conjugam-se na reelaboração de um pensamento de comunidade. Por meio da reflexão sobre o papel que esses ensaios e outras publicações e jornais tiveram na organização de projetos coletivos e na construção de consciências de comunidade e identidade, o intuito é argumentar a respeito de um paradigma periódico que se expande na contemporaneidade, ganhando campo em manifestações de caráter estético-político, estéticas e escrituras urbanas e em dinâmicas digitais, articulando lutas, resistências e insistências.
Una vida entre la imagen y la letra: Joan Ponç en Brasil
Authors: Santos Margareth Dos 
Published: January 2021

Ese artículo discute la escritura íntima del pintor catalán Joan Ponç (1927-1984) a fin de delinear parte de su historia en Brasil, cuyo tránsito por el medio artístico-cultural brasileño se fijó en una narrativa cristalizada en dos vías: en su producción pictórica, en su diario y correspondencia, cultivados en su estancia paulistana y en su retorno a Cataluña. Para pensar su naturaleza híbrida, configurada entre el mundo de “yo” y el de los otros, el análisis explorará archivos personales del pintor y de sus exalumnos brasileños a través de una escritura de fondo ensayístico, con el intuito de excavar las posibilidades de tanteo hacia la recuperación de un pasado reordenado y recriado por una mano que pinta y escribe.

Translating Lucy
Authors: Gomes Francisco Wellington Borges , Ribeiro Isabella Nojosa 
Published: January 2021

Since the beginning of the cinema industry, literature has been influencing movies both in direct and indirect forms. Intersemiotic translation is the main tool on that process once it involves transferring meaning from a system of signs to another. It generally consists of the translation of written media into an audiovisual text (JACOBSON, 1969), taking into consideration all the different specifications and characteristics of each support. Under the perspective of Translation Studies, this article aims to reflect upon the intersemiotic translation of the character Lucy Pevensie, from the literary work “The Chronicles of Narnia: The lion, The Witch and The Wardrobe” to the cinematic narrative released in 2005, directed by Andrew Adamson and produced by Walden Media. For that, the presence of feminist aspects in both written and filmic depiction of the character are analyzed. The results show that being produced in different cultural moments, book and film bring different perspectives on feminism, as the film intends to update the literary work by recovering similar meanings though different narrative audiovisual strategies.

Self-Help/Mutual Aid Groups and Peer Support
Authors: Borkman Thomasina , Munn-Giddings Carol , Boyce Melanie 
Published: January 2021

Abstract
English-language social and behavioral science research into US self-help/mutual aid groups and nonprofit organizations (e.g., Alcoholics Anonymous, Parents Without Partners, or bereavement groups) is reviewed. The review begins in the 1960s and proceeds into the new millennium, when institutionalized self-help/mutual aid was co-opted and renamed “support groups” by professionals. SHGs are intentionally created, single-issue, voluntary member-run mutual benefit groups that value the authority of lived experience, are cost-free, and where peers give and receive help from each other. Research attention expanded to European and Asian research in the 1990s, but has now switched to mental health peer support.
Impact of Obesity on Tranexamic Acid Efficacy in Adult Patients With Major Bleeding
Authors: Franz Nicholas D. , Machado-Aranda David , Miller James T. , Farina Nicholas 
Published: January 2021

Background: Tranexamic acid (TXA) is an antifibrinolytic used for prophylaxis and treatment of acute bleeding. Although fixed dosing is often used in practice, weight-based dosing is sometimes used in the operating room (OR). The efficacy and safety of fixed-dose TXA is not well established in patients with above average weight or body mass index. Objective: To characterize the efficacy and safety of intravenous TXA in obese patients with major bleeding. Methods: This was a retrospective review of 165 patients receiving fixed-dose TXA for acute bleeding outside the OR. Blood product administration (BPA) before and after TXA was collected, along with demographic and bleed-related information. Thrombotic events were the major safety end point. A prespecified subgroup analysis was conducted in patients weighing at least 100 kg compared with a lower weight. Logistic regression was performed to determine whether an association exists between body weight and blood product requirement after TXA administration. Results: In the 24 hours after TXA, patients received an average of 4.17 units of blood product. Patients weighing at least 100 kg averaged 4.04 total units, compared with 4.19 units in the lower weight group ( P = 0.603). Administration of individual blood products did not differ between groups, and thrombotic events were similar. Regression analysis did not associate weight with total BPA. Conclusion and Relevance: In patients receiving fixed-dose TXA, weight does not appear to alter blood product requirements or rates of adverse thrombotic events. These data support continued use of fixed-dose TXA for treatment of acute major bleeding in obese patients.

Published: January 2021

Background Limited evidence is available regarding low (24/26 mg) and middle (49/51 mg) doses of sacubitril/valsartan. Objectives The purpose of this study was to investigate the effect of sacubitril/valsartan dose on heart failure (HF) hospitalization and mortality in patients with HF with reduced ejection fraction (HFrEF). Methods A retrospective multicenter cohort study compared 3 doses of sacubitril/valsartan in patients with HFrEF. The coprimary outcomes were all-cause mortality and rehospitalization for HF. Propensity matching analysis was performed. Results Of 721 eligible patients, propensity matching created a cohort with an effective sample size of 652 (24/26-mg group [n = 326], 49/51-mg group [n = 147], 97/103-mg group [n = 179]). The HF hospitalization rates were 29.14% in the 24/26-mg group, 19.51% in the 49/51-mg group, and 16.10% in the 97/103-mg group (24/26 vs 49/51 mg: HR = 1.56, 95% CI = 1.04-2.34; 24/26 vs 97/103 mg: HR = 1.79, 95% CI = 1.18-2.73; 49/51 vs 97/103 mg: HR = 1.15, 95% CI = 0.70-1.89). All-cause mortality rates were 29.63% in the 24/26-mg group, 17.58% in the 49/51-mg group, and 9.27% in the 97/103-mg group (24/26 vs 49/51 mg: HR = 1.67, 95% CI = 1.07-2.59; 24/26 vs 97/103 mg: HR = 2.56, 95% CI = 1.54-4.24; 49/51 vs 97/103 mg: HR = 1.54, 95% CI = 0.84-2.82). Conclusion and Relevance Sacubitril/valsartan 97/103- or 49/51-mg dose is associated with a lower mortality or hospitalization rate for HF in patients receiving sacubitril/valsartan compared with the 24/26-mg dose group.
