Comunicação e o sistema da moda: Autorreferência e Heterorreferência no desfile The Horn Of Plenty, por Alexander McQueen

This paper addresses the relationship between fashion and communication. Aiming to explain the occurrence of self-reference and hetero- reference – both of which are operations proper to an autopoietic system – within the fashion system, in Luhmann’s perspective, we elected as corpus seven dresses displayed in Alexander McQueen’s 2009-2010 Autumn-Winter fashion show The Horn of Plenty. In order to achieve the proposed objective, we betake Luhmann’s concepts of self-reference and hetero-reference, and analyze the dresses, by means of both those concepts and of Plaza’s modes of intersemiotic translation. The importance of the present paper lies upon the possibility to understand the production and reproduction of the fashion system, not through consumption tendency though.Keywords: fashion system, self-reference/hetero- reference, intersemiotic translation.A relação entre moda e comunicação é o tema deste artigo, que tem como propósito explicitar como se dá a autorreferência e a heterorreferência, operações próprias de um sistema autopoiético, na perspectiva de Luhmann, no sistema da moda. Sete trajes, exibidos no desfile The Horn of Plenty, Outono-Inverno, 2009-2010, de Alexander Mc- Queen, constituem o corpus. Para alcançar o objetivo proposto, tratamos dos conceitos de autorreferência e heterorreferência de Luhmann e analisamos os trajes valendo-nos desses conceitos e das modalidades de tradução intersemiótica propostas por Plaza. A importância deste artigo está na possibilidade de compreender a produção e a reprodução do sistema da moda, contudo, não pelo viés do consumo.Palavras-chave: sistema da moda, autorreferência/ heterorreferência, tradução intersemiótica

Infected pancreatic necrosis: outcomes and clinical predictors of mortality. A post hoc analysis of the MANCTRA-1 international study

: The identification of high-risk patients in the early stages of infected pancreatic necrosis (IPN) is critical, because it could help the clinicians to adopt more effective management strategies. We conducted a post hoc analysis of the MANCTRA-1 international study to assess the association between clinical risk factors and mortality among adult patients with IPN. Univariable and multivariable logistic regression models were used to identify prognostic factors of mortality. We identified 247 consecutive patients with IPN hospitalised between January 2019 and December 2020. History of uncontrolled arterial hypertension (p = 0.032; 95% CI 1.135-15.882; aOR 4.245), qSOFA (p = 0.005; 95% CI 1.359-5.879; aOR 2.828), renal failure (p = 0.022; 95% CI 1.138-5.442; aOR 2.489), and haemodynamic failure (p = 0.018; 95% CI 1.184-5.978; aOR 2.661), were identified as independent predictors of mortality in IPN patients. Cholangitis (p = 0.003; 95% CI 1.598-9.930; aOR 3.983), abdominal compartment syndrome (p = 0.032; 95% CI 1.090-6.967; aOR 2.735), and gastrointestinal/intra-abdominal bleeding (p = 0.009; 95% CI 1.286-5.712; aOR 2.710) were independently associated with the risk of mortality. Upfront open surgical necrosectomy was strongly associated with the risk of mortality (p < 0.001; 95% CI 1.912-7.442; aOR 3.772), whereas endoscopic drainage of pancreatic necrosis (p = 0.018; 95% CI 0.138-0.834; aOR 0.339) and enteral nutrition (p = 0.003; 95% CI 0.143-0.716; aOR 0.320) were found as protective factors. Organ failure, acute cholangitis, and upfront open surgical necrosectomy were the most significant predictors of mortality. Our study confirmed that, even in a subgroup of particularly ill patients such as those with IPN, upfront open surgery should be avoided as much as possible.

VALUTAZIONE DELLA RISPOSTA IMMUNITARIA SIERICA, MUCOSALE E CELLULO-MEDIATA CONSEGUENTE A INFEZIONE DI CAMPO DA VIRUS PRRS (PRRSV)

INTRODUZIONE: La valutazione della risposta immunitaria contro virus della Porcine Reproductive and Respiratory Syndrome (PRRS) \ue8 importante per il monitoraggio dell\u2019efficacia dei piani aziendali di controllo della malattia. Lo scopo del lavoro \ue8 stato quello di valutare e confrontare la cinetica dell\u2019immunit\ue0 umorale sierica e mucosale e cellulo-mediata in 2 gruppi di scrofette PRRS-free introdotte allevamento infetto da PRRSV. MATERIALI E METODI: La presenza del virus \ue8 stata monitorata mediante real time RT-PCR [1]. Gli anticorpi specifici nel siero, e le IgG e IgA mucosali dei fluidi orali di gruppo (ottenute tramite cordino) sono stati titolati con kit commerciali. La risposta cellulo-mediata \ue8 stata valutata tramite test di rilascio di interferone-gamma specifico per PRRSV [2, 3]. RISULTATI: La precocit\ue0 di comparsa della risposta anticorpale nel liquido orale \ue8 analoga a quella dei sieri e la positivit\ue0 del campione salivare di gruppo \ue8 assicurata anche da pochi suini sieropositivi sul totale degli utilizzatori del cordino. Le condizioni di allevamento stabile per PRRS si \ue8 associata ad una dinamica favorevole della risposta immunitaria con sostanziale accordo tra i parametri anticorpali sierici, mucosali e di risposta cellulo-mediata. Inoltre, la rilevazione della risposta anticorpale nei liquidi orali si \ue8 dimostrata assai pi\uf9 \u201crobusta\u201d rispetto alla dimostrazione del virus nel siero e nei liquidi orali stessi mediante PCR. CONCLUSIONI: Il monitoraggio sanitario per la PRRS basato sul prelievo dei liquidi orali si \ue8 dimostrato accurato e tempestivo a fronte di un impegno logistico molto ridotto rispetto ai prelievi di sangue sul singolo animale, dimostrando inoltre un sostanziale accordo tra i parametri anticorpali sierici, mucosali e di risposta cellulo-mediata

ANALISI COMPARATIVA DI PARAMETRI IMMUNOLOGICI SIERICI, MUCOSALI E CELLULO-MEDIATI DOPO INFEZIONE DI CAMPO DA VIRUS PRRS (PRRSV)

Scopo di questo lavoro \ue8 stato confrontare lo sviluppo temporale dell\u2019immunit\ue0 umorale e cellulo-mediata in 2 gruppi di scrofette PRRS-free introdotte in un allevamento da riproduzione infetto da PRRSV. In particolare, sono stati analizzati anticorpi IgG sierici, IgG ed IgA salivari, risposta cellulo-mediata (test di rilascio di interferon-gamma speciico per PRRSV). Tali parametri sono stati valutati al ine di evidenziare possibili differenze nello sviluppo e nella cinetica della risposta immunitaria nei confronti del virus della PRRS. Le scrofette hanno contratto l\u2019infezione attorno alle 7-9 settimane dall\u2019ingresso in allevamento. Sono emersi in particolare 4 risultati salienti: A) la precocit\ue0 della risposta Ab nei liquidi orali di gruppo \ue8 analoga a quella evidenziata nei sieri; B) buone condizioni di sanit\ue0, benessere e conduzione aziendale si associano ad una precoce risposta immunitaria umorale e, soprattutto cellulo-mediata (test IFNgamma), a differenza di quello che si osserva in allevamenti \u201cproblema\u201d per PRRS; C) la risposta cellulo-mediata presenta differenze anche elevate tra soggetti dello stesso gruppo, ma i gruppi tendono a distinguersi chiaramente tra loro rispetto a tale parametro; D) la positivit\ue0 anticorpale nel liquido orale di gruppo viene assicurata anche solo da pochi suini sieropositivi sul totale degli 8-10 soggetti che depositano i liquidi orali. Sono state osservate inine alcune criticit\ue0 riguardo all\u2019uso del cordino di gruppo per il recupero dei liquidi orali in suini di et\ue0 > 12 settimane, da affrontare con opportune modiiche del protocollo d\u2019impiego

The prevalence of vegetative and minimally conscious states: A systematic review and methodological appraisal

OBJECTIVES: To systematically review prevalence studies of vegetative state (VS) and minimally conscious state (MCS) in geographically defined populations, to appraise study methods and assess sources of heterogeneity. METHODS: MEDLINE, EBM Reviews, and EMBASE databases were searched using key terms. Two reviewers independently identified pertinent articles and screened the references for additional studies. Studies measuring the prevalence of VS and/or MCS in a defined population were included, and information on characteristics, methods, and results was extracted. Heterogeneity was quantified through the statistic I. RESULTS: We identified 5 cross-sectional prevalence surveys of VS and 1 of MCS. Prevalence ranged from 0.2 cases per 100,000 inhabitants to 3.4 for VS and was 1.5 per 100,000 for MCS. Relevant heterogeneity (I = 99.0%) prevented us from calculating a summary estimate. The prevalence of trauma cases varied from 21.9% to 53.8%. Variability pertaining to diagnostic criteria, definition of case, and methods of ascertainment was found. CONCLUSION: In the few prevalence studies of VS and MCS that were identified, the estimates showed high variability and could not be pooled. Future studies should consider using comparable methods for the definition, ascertainment, and confirmation of cases

Phylodynamic analysis of current Porcine circovirus 4 sequences: Does the porcine circoviruses evolutionary history repeat itself?

Four porcine circoviruses (PCVs) have been discovered over time and seem to share a common history, particularly for PCV-2 and -3. Despite being reported as apparently new viruses, rapidly emerging as a threat for the worldwide swine industry, they were then proven to have been circulating and coexisting with domestic pigs undetected for decades, without causing relevant health issues. A similar scenario could be true for the most recently identified PCV-4. However, its detection in Asia only and the limited genetic variability could suggest a truly recent origin. To investigate which of the above-mentioned scenarios is more plausible, a phylodynamic analysis was performed on all available PCV-4 sequences for which adequate metadata were available to reconstruct the viral history and evolution. Obtained results suggest an ancient origin, at least decades ago, followed by a prolonged low-level circulation and a moderate increase in viral population size after the second half of the XX century, in parallel with a progressive rise in pig population and farming intensification. A relevant local geographical clustering was also highlighted. The reason behind such low spreading capacity and limited geographical distribution compared to other circoviruses is currently obscure and will require dedicated studies, involving a more extensive sampling and sequencing activity

Microbiological quality of well water of swine farms: one year survey

Water is an essential nutrient for livestock and farmers frequently use groundwater for animal watering. While the quality of water for human consuption is strictly regulated no specific requirements exist regarding biological, chemical and physical parameters of the water for livestock supply [1]. The aim of this study was to conduct a baseline study evaluating some microbiological parameters of water for livestock supply
