Effects of Climate Change on the Production of Polysaccharides and Phycobiliproteins by Nostoc commune Vaucher ex Bornet et Flahault
Nostoc commune synthesizes polysaccharides and phycobiliproteins under natural conditions, but little is known about how
environmental changes could affect their production. In this study, colonies of N. commune were subjected to increases in
ultraviolet radiation, ammonium concentration, electrical conductivity, and temperature, to assess the potential changes in
the concentrations of polysaccharides and phycobiliproteins. The results indicate that UVB radiation significantly increased
the synthesis of polysaccharides (F = 62.691; p < 0.01), while UVA radiation caused a significant increase in the production
of total phycobiliproteins (F = 22.472, p < 0.01) phycocyanin (F = 8.546, p < 0.01), phycoerythrin (F = 12.876, p < 0.01),
and allophycocyanin (F = 58.143, p < 0.001). Also, 50 μM NH4Cl
significantly increased the synthesis of polysaccharides
(F = 45.706; p < 0.01) while increased near significant total phycobiliproteins (F = 5.043, p < 0.1), phycoerythrins (F = 4.57,
p < 0.1), allophycocyanin (F = 4.892, p < 0.1), and phycocyanin (F = 4.921, p < 0.1). Furthermore, a conductivity value of
4 mScm−
1 enhanced near significant the production of polysaccharides (F = 4.816; p < 0.1) and phycocyanin (F = 9.728,
p < 0.1). Nevertheless, a significant effect of total phycobiliproteins was observed (F = 23.686, p < 0.01), as well as allophycocyanin
(F = 57.092, p < 0.001), and phycoerythrin (F = 13.928, p < 0.01). Finally, the optimal temperature for the synthesis
of polysaccharides was 30 °C. Also, 30 ºC significantly increased the synthesis of total phycobiliproteins (F = 292.211,
p < 0.001), as well as on phycocyanin (F = 126.433, p < 0.001) and allophycocyanin (F = 7.991, p < 0.05). These data indicate
the ability of N. commune to modify its synthesis of polysaccharides and phycobiliproteins in response to extreme
environmental conditions related to climate change, underscoring the interest in N. commune for future applied research on
the biotechnological and pharmaceutical production of both types of compounds
Intervención educativa: Capacitación de estudiantes de la Facultad de Enfermería, Fisioterapia y Podología en la elaboración de un trabajo fin de grado mediante cuestionarios de autoaprendizaje
Se crea una herramienta en el Campus Virtual (CV), en formato de Libro de Moodle, que permita la orientación del estudiante en el proceso de elaboración del Trabajo Fin de Grado (TFG), mediante el procedimiento de Preguntas Frecuentes que vayan contestando a las principales inquietudes y carencias del estudiante al enfrentarse a dicha tarea.
Asimismo se diseña un cuestionario de Autoevaluación de conocimientos y habilidades que permita al estudiante apreciar su progreso en el manejo de los conceptos relacionados con su trabajo.
Por último se pretende identificar el nivel de conocimientos y habilidades adquirido por los estudiantes, de forma que podamos evaluar la eficacia de nuestra intervención educativa. Este objetivo lo abordaremos con procedimientos de cuantitativos y cualitativos

Preanalytical issues related to routine and diagnostic glucose tests: Results from a survey in Spain
Introduction: Diabetes mellitus (DM) is one of the most prevalent diseases worldwide. The objective of this study was to find out under what preanalytical conditions routine and diagnostic glucose tests are performed across Spanish laboratories; and also what criteria are used for DM diagnosis.
Materials and methods: An online survey was performed by the Commission on Quality Assurance in the Extra-Analytical Phase of the Spanish Society of Laboratory Medicine (SEQC-ML). Access to the questionnaire was available on the home page of the SEQC-ML website during the period April-July 2018. Data analysis was conducted with the IBM SPSS© Statistics (version 20.0) program.
Results: A total of 96 valid surveys were obtained. Most laboratories were in public ownership, serving hospital and primary care patients, with high and medium workloads, and a predominance of mixed routine-urgent glucose testing. Serum tubes were the most used for routine glucose analysis (92%) and DM diagnosis (54%); followed by lithium-heparin plasma tubes (62%), intended primarily for urgent glucose testing; point-of care testing devices were used by 37%; and plasma tubes with a glycolysis inhibitor, mainly sodium fluoride, by 19%. Laboratories used the cut-off values and criteria recognized worldwide for DM diagnosis in adults and glucose-impaired tolerance, but diverged in terms of fasting plasma glucose and gestational DM criteria.
Conclusion: Preanalytical processing of routine and DM diagnostic glucose testing in Spain does not allow a significant, non-quantified influence of glycolysis on the results to be ruled out. Possible adverse consequences include a delay in diagnosis and possible under-treatment

Role of age and comorbidities in mortality of patients with infective endocarditis
[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality.
[Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk.
[Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality.
[Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group
