Case, definiteness and noun phrases in Armenian
Este trabalho trata da organização de sintagmas nominais no armênio, revelando uma interação peculiar entre a expressão de definitude e a marcação morfológica de Caso e as conseqüências dessa relação para a organização estrutural desta língua. Mostra se que os sintagmas nominais são interpretados como definidos como resultado de atribuição de Caso estrutural, e que existe uma assimetria entre os Casos estruturais e os Casos inerentes quanto à atribuição de definitude. Como ponto de partida, discute-se o estatuto do sufixo n/y, chamado de artigo definido pela gramática tradicional do armênio. A investigação das propriedades morfossintáticas desse sufixo mostra que o mesmo é uma marca com características mistas, que atua na atribuição de definitude e Caso de uma maneira não atestada nas línguas naturais e questiona o recorte entre as funções de Caso e os meios de expressão de definitude. Baseando-nos nos trabalhos de Chomsky (1986b), Longobardi (1994) e Giusti (2002), propomos a reanálise do sufixo -n/y como uma marca de Caso estrutural, que transforma os sintagmas nominais em argumentos sintáticos, e é associada ao nível DP na estrutura frasal. Ademais, mostra-se que a ausência de marcação de Caso estrutural resulta numa série de restrições semântico-sintáticas nos sintagmas nominais (nus), a mais proeminente sendo o movimento desses sintagmas para uma posição antes do verbo, seguidos imediatamente pelo auxiliar. Isso leva a diferentes ordens superficiais para sintagmas marcados por Caso estrutural (SVO) e sintagmas nus (SOauxV). Tal evidência, junto com o quadro das características dos sintagmas nus no armênio, leva à análise dos mesmos como pseudo-incorporados, conforme proposto por Massam (2001) para o niueano, com a diferença de que o sintagma nu se adjunge à projeção funcional TP no armênio, sem passar pela operação de alçamento do predicado. Quanto à expressão de definitude nos Casos inerentes, mostramos que em contraste com os sintagmas nos Casos estruturais, que podem aparecer com ou sem marcação aberta de Caso e ter, respectivamente, leitura definida ou indefinida, os inerentes devem sempre carregar a morfologia casual e são ambíguos quanto à definitude. Nesse aspecto, analisamos as projeções nominais Genitivas e constatamos que, apesar da aparente semelhança superficial, as mesmas exibem propriedades distintas que correspondem a duas estruturas internas diferentes do sintagma nominal, viii podendo ser caracterizadas como duas classes distintas: o Genitivo Referencial, que aparece em Spec/DP e é interpretado como definido por se associar ao nível DP, e o Genitivo Modificador, que permanece no domínio do NP no percurso da derivação. As conclusões a que chegamos provam que mesmo sem possuir um artigo definido canônico, o armênio oferece evidências a favor da postulação do nível DP como universal, responsável pelas interpretações definidas dos sintagmas nominais. Nos Casos estruturais, a definitude vem da atribuição de Caso, enquanto no Genitivo (um exemplo de Caso inerente) vem da posição ocupada dentro do sintagma nominal. Por conseguinte, o presente trabalho traz uma contribuição teórica valiosa para a análise unificada das projeções nominais, além de auxiliar na elucidação de alguns assuntos empíricos controversos do armênio e abrir caminho para pesquisas futuras.This thesis investigates the structural organization of noun phrases in Armenian, an Indo-European language with mixed properties, focusing on the interaction between Case and (in)definiteness. The main claim of the study is that, contrary to traditional view, Armenian has no (definite) article, and definiteness in this language is a result of structural Case marking on NPs. This claim has implications for the analysis of bare nominals as NPs that lack both Case and referential properties and are syntactically restricted to a peculiar configuration, resulting in different superficial orders for Case-marked (SVO) and bare noun phrases (SOauxV). Moreover, this analysis casts light on a rather intriguing question of how definiteness is expressed in inherent Cases. It is shown that, unlike structural Cases, which express a direct correlation between definiteness and Case, inherent Cases, more precisely Genitive NPs, are interpreted as (in)definite by associating themselves to distinct structural positions. The starting point of our discussion is the re-analysis of the suffix -n/y, traditionally classified as a definite article. Highlighting Case and (in)definiteness as two independent conditions on argumenthood (Chomsky (1986b), Longobardi (1994), Giusti (2002)) that are closely correlated in Armenian, we argue that this suffix is in fact a structural Case marker, which turns nominals into syntactic arguments, and is associated with DP level. Focusing on the morpho-syntactic behavior of bare nominals in Armenian, it is shown that in the absence of structural Case marking, their distribution is syntactically restricted to a position in which they appear to the left of the verb and must be adjacent to the auxiliary. This distribution is accounted for by adopting the pseudo-incorporation analysis of Massam (2001). We show that bare nouns in Armenian exhibit typical properties of pseudo-incorporated nominals, as lack of reference, number-neutrality, phrasal nature, among others. Turning our attention to Genitive constructions, which always appear with Case morphology, we analyze a number of properties that superficially distinguish two (main) types, which we propose to call Referential and Modifying Genitives. The difference between them is syntactic, as they have different structural representations: Spec/DP for Referential and NP domain for Modifying Genitive. x As a result, we conclude that there exists an asymmetry between inherent and structural Cases as to how they express definiteness. Moreover, we conclude that in spite of the fact that Armenian does not have canonical (definite) article, a DP level must be postulated for this language, as a projection responsible for the referentiality/definiteness of the noun phrases. Thus, this study contributes to the outgoing debates about the precise functions of D as universal category and provides a valuable theoretical contribution to the cross-linguistic investigations of nominal projections
Dificuldades de pronúncia de estudantes brasileiros aprendendo armênio oriental e sugestões de estratégias para superá-las
Este trabalho tem o objetivo de apresentar um levantamento das maiores dificuldades de pronúncia de estudantes brasileiros aprendendo armênio oriental e propor estratégias para tentar superar essas dificuldades. A abordagem se baseia no conceito de consciência fonológica (LIBERMAN 1973), buscando explorar principalmente características de pronúncia do próprio português brasileiro que têm um caráter alofônico ou ocorrem apenas em variação mas que no armênio apresentam caráter fonêmico. Em alguns casos se recorre nas soluções a detalhes da ortografia do português ou à fonologia de línguas mais conhecidas no Brasil
Improving the safety of the Manchester triage system for children with congenital heart disease
This study is a prospective evaluation of the validity of a Manchester triage system (MTS) modification for detecting under-triaged pediatric patients with congenital heart disease (CHD). Children with CHD visiting the emergency unit of the Department of Pediatrics and Adolescent Medicine, University Hospital Vienna in 2014 were included. The MTS modification updated the prioritization of patients with complex syndromic diseases, specific symptoms related to chronic diseases, decreased general condition (DGC), profound language impairment, unknown medical history, or special needs. A four-level outcome severity index based on diagnostic and therapeutic interventions, admission to hospital, and follow-up strategies was defined as a reference standard for the correct clinical classification of the MTS urgency level. Of the 19,264 included children, 940 had CHD. Of this group, 266 fulfilled the inclusion criteria for the modified triage method. The MTS modification was significantly more often applied in under-triaged (65.9%) than correctly or over-triaged (25%) children with CHD (p-value χ2 test <0.0001, OR 5.848, 95% CI: 3.636–9.6). Conclusion: The MTS urgency level upgrade modification could reduce under-triage in children with CHD. Applying a safety strategy concept to the MTS could mitigate under-triage in such a high-risk patient group
Data_Sheet_1_Exposure to soiled bedding reduces abnormal repetitive behaviors in mice.PDF
Hygiene management protocols in laboratory mouse husbandries worldwide most commonly employ soiled bedding-exposed sentinel mice to monitor the occurrence of infections in mouse colonies. Using this approach, sentinel mice repeatedly receive a mixture of used bedding, supplied by a variety of cages of a defined hygienic unit for a period of several months. Hereby, microorganisms shed in the used bedding can infect the sentinel animals and can be detected in subsequent health monitoring procedures. However, murine excrements carry more than only microorganisms. Mouse feces and urine also contain a multitude of olfactory molecules, which the animals use to code information about social status and context. However, if and how the persistent and repeated experience with these odor cues affects the behavior of sentinel mice, has not yet been explored. To address this question, we conducted a longitudinal study for neurochemical output parameters related to an organism’s responsiveness to challenging conditions, and for the exploratory assessment of a panel of home cage behaviors in soiled bedding and control female C57BL/6J mice. We found that the number of mice showing abnormal repetitive behaviors, including barbering and bar mouthing, was lower in the soiled bedding group. While neutrophil/lymphocyte ratios and fecal corticosterone metabolites did not differ between groups, the within-group variance of the neutrophil/lymphocyte ratio was reduced in the soiled bedding group. These results show that the occurrence of abnormal repetitive behaviors is lower in sentinel than in control mice and suggest a beneficial effect of soiled bedding on the welfare of laboratory mice and on outcome variability.</p
Identification of Potentially Tolerated Fish Species by Multiplex IgE Testing of a Multinational Fish-Allergic Patient Cohort
Background: Although recent studies indicated that many fish-allergic patients may safely consume certain fish species, no clinical guidelines are available for identification of the exact species tolerated by specific patients.
Objective: To investigate whether multiplex immunoglobulin E (IgE) testing reveals potentially tolerated fish through absence of IgE to parvalbumin (PV) and extracts from specific species.
Methods: Sera from 263 clinically well-defined fish-allergic patients from Austria, China, Denmark, Luxembourg, Norway, and Spain were used in a research version of the ALEX 2 multiplex IgE quantification assay. Specific IgE to PVs from 10 fish species (9 bony and 1 cartilaginous), and to extracts from 7 species was quantified. The IgE signatures of individual patients and patient groups were analyzed using SPSS and R.
Results: Up to 38% of the patients were negative to cod PV, the most commonly used molecule in fish allergy diagnosis. Forty-five patients (17%) tested negative to PVs but positive to the respective fish extracts, underlining the requirement for extracts for accurate diagnosis. Between 60% (Spain) and 90% (Luxembourg) of the patients were negative to PV and extracts from ray, a cartilaginous fish, indicating its potential tolerance. Up to 21% of the patients were negative to at least 1 bony fish species. Of the species analyzed, negativity to mackerel emerged as the best predictive marker of negativity to additional bony fish, such as herring and swordfish.
Conclusions: Parvalbumins and extracts from multiple fish species relevant for consumption should be used in fish-allergy diagnosis, which may help identify potentially tolerated species for individual patients
Immunogenicity and reactogenicity of a first booster with BNT162b2 or full-dose mRNA-1273 : a randomised VACCELERATE trial in adults 6575\ua0years (EU-COVAT-1)
Abstract: Background Vaccination remains crucial for protection against severe SARS-CoV-2 infection, especially for people of advanced age, however, optimal dosing regimens are as yet lacking. Methods EU-COVAT-1-AGED Part A is a randomised controlled, adaptive, multicentre phase II trial evaluating safety and immunogenicity of a 3rd vaccination (1st booster) in individuals 6575 years. Fifty-three participants were randomised to full-doses of either mRNA-1273 (Spikevax\uae, 100 \ub5g) or BNT162b2 (Comirnaty\uae, 30 \ub5g). The primary endpoint was the rate of 2-fold circulating antibody titre increase 14 days post-vaccination measured by quantitative electrochemiluminescence (ECL) immunoassay, targeting RBD region of Wuhan wild-type SARS-CoV-2. Secondary endpoints included the changes in neutralising capacity against wild-type and 25 variants of concern at 14 days and up to 12 months. Safety was assessed by monitoring of solicited adverse events (AEs) for seven days after on-study vaccination. Unsolicited AEs were collected until the end of follow-up at 12 months, SAEs were pursued for a further 30 days. Results Between 08th of November 2021 and 04th of January 2022, 53 participants 6575 years received a COVID-19 vaccine as 1st booster. Fifty subjects (BNT162b2 n = 25/mRNA-1273 n = 25) were included in the analyses for immunogenicity at day 14. The primary endpoint of a 2-fold anti-RBD IgG titre increase 14 days after vaccination was reached for all subjects. A 3rd vaccination of full-dose mRNA-1273 provided higher anti-RBD IgG titres (Geometric mean titre) D14 mRNA-127310711 IU/mL (95 %-CI: 8003;14336) vs. BNT162b2: 7090 IU/mL (95 %-CI: 5688;8837). We detected a pattern showing higher neutralising capacity of full-dose mRNA-1273 against wild-type as well as for 23 out of 25 tested variants. Interpretation Third doses of either BNT162b2 or mRNA-1273 provide substantial circulating antibody increase 14 days after vaccination. Full-dose mRNA-1273 provides higher antibody levels with an overall similar safety profile for people 6575 years
Safety and effectiveness outcomes from a 14-country cohort of patients with multi-drug resistant tuberculosis treated concomitantly with bedaquiline, delamanid and other second-line drugs.
BACKGROUND: Concomitant use of bedaquiline (Bdq) and delamanid (Dlm) for multi-drug/rifampicin resistant tuberculosis (MDR/RR-TB) has raised concerns about a potentially poor risk-benefit ratio. Yet, this combination is an important alternative for patients infected with strains of TB with complex drug resistance profiles or who cannot tolerate other therapies. We assessed safety and treatment outcomes of MDR/RR-TB patients receiving concomitant Bdq and Dlm, along with other second-line anti-TB drugs. METHODS: We conducted a multi-centric, prospective observational cohort study across 14 countries among patients receiving concomitant Bdq-Dlm treatment. Patients were recruited between April 2015 and September 2018 and were followed until the end of treatment. All serious adverse events and adverse events of special interest (AESI), leading to a treatment change, or judged significant by a clinician, were systematically monitored and documented. RESULTS: Overall, 472 patients received Bdq and Dlm concomitantly. A large majority also received linezolid (89.6%) and clofazimine (84.5%). Nearly all (90.3%) had extensive disease; most (74.2%) had resistance to fluoroquinolones. The most common AESI were peripheral neuropathy (134, 28.4%) and electrolyte depletion (94, 19.9%). Acute kidney injury and myelosuppression were seen in 40 (8.5%) and 24 (5.1%) of patients, respectively. QT prolongation occurred in 7 (1.5%). Overall, 78.0% (358/458) had successful treatment outcomes, 8.9% died and 7.2% experienced treatment failure. CONCLUSIONS: Concomitant use of Bdq and Dlm, along with linezolid and clofazimine, is safe and effective for MDR/RR-TB patients with extensive disease. Using these drugs concomitantly is a good therapeutic option for patients with resistance to many anti-TB drugs
