Elementos de poética en la gramática latina: el género lírico

The fifteenth-century Italian humanist Franciscus Niger reintroduces in his Breuis Grammatica (1480), an issue scarcely developed in Roman grammars and completely absent from medieval ones, i.e. the description of poetic genres. Niger’s innovation is taken over by his German follower Nicolaus Marscalcus in a grammar composed in 1501. In this paper, the ideas on the lyric kind in both texts are analysed and compared with the inherited tradition. These humanists are relevant both as the receptors and unprecedented comprehensive formulators of the doctrine on one of the most loosely depicted genres in this tradition comprising ancient and medieval sources of diverse kinds, and just about before the burgeoning of poetic theories in the sixteenth century that will eventually make of the lyric an independent genre.El humanista italiano Franciscus Niger reintroduce en su Breuis Grammatica de 1480 un capítulo muy limitado en las artes romanas y totalmente ausente de las gramáticas medievales: el de la caracterización de los géneros poéticos. En el presente trabajo se estudia la doctrina relativa al género lírico en dicha gramática y en la de su seguidor Nicolaus Marscalcus, compuesta en 1501, comparándola con la tradición anterior. Ambos textos humanistas suponen la recepción y el más amplio desarrollo de una doctrina, formada durante siglos y transmitida en fuentes antiguas y medievales de muy diversa índole, sobre uno de los géneros más desdibujados, justo antes de la proliferación de teorías poéticas en el siglo XVI, que acaban convirtiendo a la lírica en un género independiente

Analysis of bacterial communities of infected primary teeth in a Mexican population

The objective of this study was to describe the bacterial communities associated with pediatric patients with endodontic infections of temporal teeth by targeting the 16S rRNA gene using pyrosequencing. Microbiological samples were obtained from the lower primary molars of thirteen 13 pediatric patients with dental infections. An aspiration method for microbiological sampling was used. The identification of microbiota employing the pyrosequencing method by targeting the 16S gene was performed. Ribosomal 16S RNA gene sequences were amplified, obtaining a total of 16,182 sequences from 13 primary infected molars (13 different individuals) by pyrosequencing. Bacteroidetes phyla (35.15%) were the most abundant followed by Firmicutes (33.3%) and Fusobacteria (10.05%); the presence of specific pathogenic bacteria was determined as well. The infected root canal of primary teeth contains a high diversity of anaerobic bacteria, and Bacteroidetes, Firmicutes, and Fusobacteria phyla were the most abundant; Prevotella and Streptococcus genera were the most prevalent

Adherencia a la guía de práctica clínica de sepsis neonatal según tipo de sepsis en un Instituto Materno Perinatal de Lima, Perú

Objective: The objective of this research is to describe adherence to the neonatal sepsis clinical practice guideline according to the type of sepsis in a perinatal maternal institute in Lima, Peru. Method: A descriptive study was carried out between the months of June to December 2021 at the Instituto Nacional Maternal Perinatal (INMP). The adherence of care to the CPG for the prevention, diagnosis and treatment of neonatal sepsis based on the INMP evidence was evaluated. Medical care was evaluated by two physicians who reviewed compliance or not with the 16 CPG recommendations. Adequate adherence was considered to be compliance of 80% or more of the recommendations established by the guideline in one care. Global adherence was calculated in percentages, by dimensions, by item and according to maternal and perinatal characteristics of care. Results: A total of 968 medical attentions were evaluated, of which 553 were early neonatal sepsis cases and 435 late. For early sepsis, an adherence of 84.4% was found, while for late sepsis, 66.8% was found. The lowest percentage of adherence was found in recommendations 2.7 and 3.2 of late sepsis care. Conclusions: An adequate adherence was found in early neonatal sepsis care, while, in relation to late neonatal sepsis, an adequate level of adherence was not reached.Objetivo: El objetivo de la presente investigación es describir adherencia a la guía de práctica clínica de sepsis neonatal según tipo de sepsis en un instituto materno perinatal de Lima, Perú. Método: Se elaboró un estudio descriptivo entre los meses de junio a diciembre del 2021 en el Instituto Nacional Materno Perinatal (INMP). Se evaluó la adherencia de las atenciones a la GPC de prevención, diagnóstico y tratamiento de sepsis neonatal basada en la evidencia del INMP. Las atenciones médicas fueron evaluadas por dos médicos quienes revisaron el cumplimiento o no de las 16 recomendaciones de la GPC enmarcadas en 6 dimensiones. Se consideró adherencia adecuada a un cumplimiento de 80% a más de las recomendaciones establecidos por la guía en una atención. Se calculó en porcentajes la adherencia global, por dimensiones, por ítem y según características maternas y perinatales de las atenciones. Resultados: Se evaluaron un total de 968 atenciones médicas de las cuales 553 fueron de casos de sepsis neonatal temprana y 435 de tardía. Para sepsis temprana se encontró una adherencia del 84.4% mientras que para sepsis tardía se encontró un 66.8%. El menor porcentaje de adherencia se encontró en las recomendaciones 2.7 y 3.2 de las atenciones de sepsis tardía. Conclusiones: Se encontró una adherencia adecuada en las atenciones de sepsis neonatal temprana, mientras que, en relación con la sepsis neonatal tardía, no se alcanzó un nivel de adherencia adecuado

Impact of interstitial lung disease on the survival of systemic sclerosis with pulmonary arterial hypertension

To assess severity markers and outcomes of patients with systemic sclerosis (SSc) with or without pulmonary arterial hypertension (PAH-SSc/non-PAH-SSc), and the impact of interstitial lung disease (ILD) on PAH-SSc. Non-PAH-SSc patients from the Spanish SSc registry and PAH-SSc patients from the Spanish PAH registry were included. A total of 364 PAH-SSc and 1589 non-PAH-SSc patients were included. PAH-SSc patients had worse NYHA-functional class (NYHA-FC), worse forced vital capacity (FVC) (81.2 ± 20.6% vs 93.6 ± 20.6%, P < 0.001), worse tricuspid annular plane systolic excursion (TAPSE) (17.4 ± 5.2 mm vs 19.9 ± 6.7 mm, P < 0.001), higher incidence of pericardial effusion (30% vs 5.2%, P < 0.001) and similar prevalence of ILD (41.8% vs. 44.9%). In individuals with PAH-SSc, ILD was associated with worse hemodynamics and pulmonary function tests (PFT). Up-front combination therapy was used in 59.8% and 61.7% of patients with and without ILD, respectively. Five-year transplant-free survival rate was 41.1% in PAH-SSc patients and 93.9% in non-PAH-SSc patients (P < 0.001). Global survival of PAH-SSc patients was not affected by ILD regardless its severity. The multivariate survival analysis in PAH-SSc patients confirmed age at diagnosis, worse NYHA-FC, increased PVR, reduced DLCO, and lower management with up-front combination therapy as major risk factors. In conclusion, in PAH-SSc cohort risk of death was greatly increased by clinical, PFT, and hemodynamic factors, whereas it was decreased by up-front combination therapy. Concomitant ILD worsened hemodynamics and PFT in PAH-SSc but not survival regardless of FVC impairment

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

Plasma lipid profiles discriminate bacterial from viral infection in febrile children

Fever is the most common reason that children present to Emergency Departments. Clinical signs and symptoms suggestive of bacterial infection are often non-specific, and there is no definitive test for the accurate diagnosis of infection. The 'omics' approaches to identifying biomarkers from the host-response to bacterial infection are promising. In this study, lipidomic analysis was carried out with plasma samples obtained from febrile children with confirmed bacterial infection (n = 20) and confirmed viral infection (n = 20). We show for the first time that bacterial and viral infection produces distinct profile in the host lipidome. Some species of glycerophosphoinositol, sphingomyelin, lysophosphatidylcholine and cholesterol sulfate were higher in the confirmed virus infected group, while some species of fatty acids, glycerophosphocholine, glycerophosphoserine, lactosylceramide and bilirubin were lower in the confirmed virus infected group when compared with confirmed bacterial infected group. A combination of three lipids achieved an area under the receiver operating characteristic (ROC) curve of 0.911 (95% CI 0.81 to 0.98). This pilot study demonstrates the potential of metabolic biomarkers to assist clinicians in distinguishing bacterial from viral infection in febrile children, to facilitate effective clinical management and to the limit inappropriate use of antibiotics
