Consideraciones sobre Statice dianiae Pau (Plumbaginaceae)

An apomictic Limonium with a single pollen-stigma combination (B type), Limonium interjectum, is proposed as a new species to replace the invalid name Statice dianiae Pau. The new species has a restricted distribution on the sea costs of eastern Spain (Alicante Province). It shows a striking morphological similarity to L. virgatum (Willd.) Fourr. and L. girardianum (Guss.) Girard; on this basis it is suggested that L. interjectum is a hybrid derived from the two species.Se describe Limonium interjectum como especie nueva del Levante peninsular español, el cual había sido previamente denominado con el nombre ilegítimo de Statice dianiae Pau. L. interjectum es una especie apomíctica que presenta una sola combinación polínico estigmática (tipo B). Sus afinidades morfológicas son próximas a L. virgatum (Willd.) Fourr. Y L. girardianum (Guss.) Girard, y se sugiere que L. interjectum es un taxon hibridógeno que pudo haberse originado a partir de ambas especies

Antibiotic resistant Gram-negative bacteria in long-term care facilities, an epidemiological and dynamic modelling study

Tackling antimicrobial resistance (AMR) is a national and global priority. Despite this, much of our understanding of the epidemiology and transmission of AMR outside the hospital, and thus, how we might control it, remains limited. Long term care facilities (LTCFs) play an important role in the care of older people. However, there have been few studies of the epidemiology and transmission of AMR in this setting. LTCF residents present with frequent co-morbidities which increase their risk of hospitalisation and of AMR infection. LTCFs also offer opportunities for transmission of AMR strains due to the long lengths of stay of residents and the lack of strictly applied infection control measures. This thesis focuses on urinary tract infections (UTIs), one of the most common bacterial infections in LTCFs, hospitals and the community. I first present a systematic review of mathematical models of infectious disease transmission set in LTCFs and a critical review of mathematical models evaluating interventions against AMR bacteria in LTCFs. A checklist for good quality models in this area is proposed. Next, using data from routinely collected microbiology samples, the frequency of AMR in urinary tract E. coli and Klebsiella was compared in LTCF residents with that in older people living in their own homes. Residents of LTCFs had more than four times the rate of E. coli and Klebsiella UTI caused by antibiotic-resistant bacteria compared with those living in the community. The seasonality of UTI consultations was also assessed. A September to November peak in UTI consultation incidence was observed for ages 14-69. This seasonality progressively faded in older age groups and no seasonality was found in individuals aged 85 and over. Finally, a stochastic compartmental mathematical model was developed to explore the transmission of trimethoprim-resistant E. coli in LTCFs. Different treatment, importation and transmission scenarios were addressed

Risk of neonatal care unit admission in small for gestational age fetuses at term: a prediction model and internal validation.

OBJECTIVE: Small for gestational age (SGA) fetuses are at increased risk of admission to the neonatal unit, even at term. We aimed to develop and validate a predictive model for the risk of prolonged neonatal unit admission in suspected SGA fetuses at term. METHODS: A single-center cohort study of singleton pregnancies with SGA fetus, defined as estimated fetal weight (EFW) less than the 10th centile, at term. The variables included known risk factors for neonatal unit admissions: maternal characteristics, EFW, abdominal circumference (AC), fetal Dopplers, gestational age (GA) at delivery, and intrapartum risk factors (meconium, pyrexia). Logistic regression analysis was used for model building and the prediction models were validated internally using bootstrapping. RESULTS: 701 SGA pregnancies at term were included; 5.9% had prolonged neonatal unit admission (> 48 hours). The multivariable model (AUC 0.71; 95% CI: 0.63-0.79) included GA at delivery < 39 weeks (OR 2.76; 95% CI 1.23-6.04, p = 0.011), cerebroplacental ratio (CPR) multiples of median (MoM) (OR 0.21; 95% CI 0.05-0.79, p = 0.023), and EFW below the third centile (OR 2.43; 95% CI 1.26-4.68, p < 0.007). The combined model showed a sensitivity 30.9% (95% CI: 16.6-45.2%) for a fixed 10% false positive rate. CONCLUSION: The prediction model shows good accuracy and good calibration for assessing the risk of neonatal unit admission in suspected SGA fetuses. It has the potential to be used for patient counseling, determining the timing of delivery and the individual risk

Understanding the impact of interventions to prevent antimicrobial resistant infections in the long-term care facility; a review and practical guide to mathematical modelling

(1) To systematically search for all dynamic mathematical models of infectious disease transmission in long-term care facilities (LTCFs); (2) to critically evaluate models of interventions against antimicrobial resistance (AMR) in this setting; and (3) to develop a checklist for hospital epidemiologists and policy makers by which to distinguish good quality models of AMR in LTCFs. The CINAHL, EMBASE, Global Health, MEDLINE, and Scopus databases were systematically searched for studies of dynamic mathematical models set in LTCFs. Models of interventions targeting methicillin-resistant Staphylococcus aureus in LTCFs were critically assessed. Using this analysis, we developed a checklist for good quality mathematical models of AMR in LTCFs. Overall, 18 papers described mathematical models that characterized the spread of infectious diseases in LTCFs, but no models of AMR in gram-negative bacteria in this setting were described. Future models of AMR in LTCFs require a more robust methodology (ie, formal model fitting to data and validation), greater transparency regarding model assumptions, setting-specific data, realistic and current setting-specific parameters, and inclusion of movement dynamics between LTCFs and hospitals. Mathematical models of AMR in gram-negative bacteria in the LTCF setting, where these bacteria are increasingly becoming prevalent, are needed to help guide infection prevention and control. Improvements are required to develop outputs of sufficient quality to help guide interventions and policy in the future. We suggest a checklist of criteria to be used as a practical guide to determine whether a model is robust enough to test policy

Model and methodology for developing empathy: an experience in computer science engineering

Contribution: This article proposes and applies a new systemic 3-D model and a methodology for empathy awareness and development, integrating different partial approaches found in the literature for developing empathy as a transversal competence. Background: Empathy is a competence linked to collaboration and teamwork. Perspective taking (PT) is an important component of empathy and it is key for professionals today. Even though empathy is valued in computer science engineering (CSE) courses, it is not yet fully addressed as an integral part of the training process. Intended Outcomes: Both the model and the methodology are put into practice with a group of first-year CSE students, highlighting the possibilities of the proposal for this course of studies. The experience presented here is an example of a classroom activity in which awareness and PT are addressed, as key components, in relation to the collaborative work toward achieving empathy. Application Design: The methodological proposal is applied to guide educators’ decisions so that they can work on empathy in the classroom. Responses to several standardized and ad-hoc questionnaires by students from two universities are analyzed. Findings: The results revealed low to medium empathy levels in participating students, but a higher perception of their own empathic ability. The proposed methodology allows students to become aware of and develop some initial changes in relation to empathy, particularly in its PT component, through classroom work

Analysis of Innovative Approaches in the Class Using Conceptual Maps and Considering the Learning Styles of Students

This paper presents innovations to stimulate the autonomy of engineering students by using different active methodologies. The strategies designed to address this problem are based on analyzing students' learning styles and incorporating specific tools into teaching practice, such as "M-eRoDes, " which supports the automatic evaluation and feedback of concept maps created by them. Among the main findings, the students' assessment of the activity "making concept maps" stands out as useful but not easy. Despite the difficulty, or precisely for that reason, the experience has contributed to improve their autonomy and to develop skills to express the knowledge they have learned

Antifungal and functional properties of starch-gellan films containing thyme (Thymus zygis) essential oil

[EN] Films based on starch-gellan blends at 9:1 and 8:2 ratios containing emulsified or lecithin encapsulated thyme (Thymus zygis) essential oil (EO) (0.25 or 0.5 g/g polymer), were obtained by casting method and characterized as to their structural, functional (mechanical, barrier and optical) and in vitro antifungal properties against Alternaria alternata (AA) and Botryotinia fuckeliana (BF). The EO retention during the film formation was also quantified. Lecithin encapsulation of the EO allowed for greater oil retention (45-55%), which enhanced the antifungal activity of the films, which were more effective against BF than AA. All films exhibited high oxygen barrier capacity, while lecithin improved the films water barrier properties and gloss, conferring them with a slightly brownish color. Lecithin also reduced the film stiffness and resistance to break and extensibility. Of the studied formulations, 8:2 S:G films with lecithin-encapsulated EO were very effective at controlling fungal growth, while exhibiting adequate functional properties as packaging/coating materials.The authors acknowledge the financial support for this study from the Ministerio de Economia y Competitividad (MINECO) of Spain, through the project AGL2016-76699-R.
