Silica Particle based nanocomposites for Specific IgE Determination to Betalactams
Current immunoassays for diagnosing betalactam (BL) allergy have limited sensitivity and poor specificity. These include ImmunoCAP, the commercial immunoassay, and the radioallergosorbent test (RAST), a handmade test performed only in specialized laboratories. Both are based on cellulose polymers modified with covalently attachedbetalactam-poly-L-lysine conjugates, which are able to interact with specific IgE (sIgE). In RAST, dendrimers have been used instead of poly-L-lysine in the formation of penicilloyl- conjugates, showing specific recognition by penicillin-sIgE.
In this work, we propose the use of nanomaterials consisting on silica particles highly functionalized with drug-dendrimer conjugates (including mono- and bi-epitopic structures), as precise and controlled solid phases able to improve the tests’ reliability. The homogeneous composition of the nano-composites provides high reproducibility and quality, which is critical for hospital applications, while silica particles possess promising properties as biocompatibility, tuneable size, and functionalisation, and their preparation is affordable and reproducible.
The use of nano-scaled silica particles improved the results of available immunoassays techniques in terms of sensitivity and specificity, providing the possibility of testing different betalactams, simultaneously.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

Diseño e implementación de estrategias y mecanismos para el soporte y desarrollo de la gestión del conocimiento en la FCEAC: Integración de procesos desde el nivel posgradual hasta el nivel pregradual
La investigación de la gestión del conocimiento se vislumbra como un fenómeno complejo que exige un esfuerzo sistemático para ir clarificando algunos elementos en torno a sus prácticas, los recursos, las competencias, las estrategias, los aprendizajes, las interrelaciones y los desempeños en los sistemas locales de Ciencia Tecnología e innovación. El esclarecimiento de estos factores demanda investigaciones con diversos enfoques y abordajes metodológicos. Esto se vuelve crítico para el caso de las Instituciones de Educación Superior, pues del desarrollo del nuevo conocimiento, depende que los demás sectores puedan recibir mucho de lo que desde allí se jalone y con el cual se debe interactuar para potenciar los procesos de desarrollo y difusión de la tecnología y, con ello, la innovación. Este proyecto pretende responder a esta exigencia del desarrollo académico-científico desde el nivel doctoral hasta la educación pregradual, orientada para el caso de la Facultad de Ciencias Económicas, Administrativas y Contables. Pero lo que es más importante es cómo se puede aplicar para el mejoramiento del desarrollo económico y social de nuestro país.Universidad Libre -- Facultad de Ciencias Económicas, Administrativas y Contables -- Contaduría Públic
Quality of Life and Autonomy in Patients with Intermittent Bladder Catheterization Trained by Specialized Nurses
Intermittent bladder catheterization (IBC) involves regular urine draining using a catheter, which is removed immediately after urinary elimination. It allows for the patient's urological health to be managed and their renal function to be preserved, and it promotes autonomy. Compliance with the prescribed number of daily catheterizations, which must be conducted by the patient, and infection prevention measures are crucial. To identify the patients requiring IBC, and to determine their adherence (whether they followed the prescribed guidelines and their difficulty in carrying out the procedure, as well as to assess how the IBC influences their quality of life and state of mind after receiving self-care training from a specialized nurse), we carried out a prospective, multicenter observational study in 24 Spanish hospitals with one month of monitoring and a sample of 99 patients. The sources of information were the patients' clinical records, the King's Health Questionnaire, the Mini-Mental State Examination (MMSE), and the hospital anxiety and depression scale (HADS). Descriptive and bivariate statistics were used to analyses the paired data. After recruitment (n = 99), 79 patients completed the questionnaire at a mean age of 35.2 years (SD = 20.5 years). In total, 53.5% (53) of the sample consisted of men and 32.3% (32) had neurological damage as the reason for prescription; 67% (67.7) performed self-catheterization and 86.7% adhered to the IBC. After one month of monitoring, a statistically significant improvement in quality of life was observed in all criteria, with the exception of personal relationships (p < 0.005), as well as an improvement in anxiety and depression levels (p < 0.001). Patients who require IBC show good adherence to the IBC with a significant percentage of self-catheterization. After one month of IBC, a significant improvement in the patients' quality of life and mood was observed. These results could be attributed to adequate patient training and adequate personalization of the IBC materials by the specialized nurses
Evolution of Quality of Life and Treatment Adherence after One Year of Intermittent Bladder Catheterisation in Functional Urology Unit Patients
Objective: To determine patient difficulties and concerns when performing IBC (Intermittent Bladder Catheterisation), as well as the evolution of adherence, quality of life, and emotional state of patients one year after starting IBC. Method: A prospective, observational, multicentre study conducted in 20 Spanish hospitals with a one-year follow-up. Data sources were patient records and the King's Health Questionnaire on quality of life, the Mini-Mental State Examination (MMSE), and the Hospital Anxiety and Depression Scale (HADS). Perceived adherence was measured using the ICAS (Intermittent Catheterization Adherence Scale) and perceived difficulties with IBC were assessed using the ICDQ (Intermittent Catheterization Difficulty Questionnaire). For data analysis, descriptive and bivariate statistics were performed for paired data at three points in time (T1: one month, T2: three months, T3: one year). Results: A total of 134 subjects initially participated in the study (T0), becoming 104 subjects at T1, 91 at T2, and 88 at T3, with a mean age of 39 years (standard deviation = 22.16 years). Actual IBC adherence ranged from 84.8% at T1 to 84.1% at T3. After one year of follow-up, a statistically significant improvement in quality of life (p <= 0.05) was observed in all dimensions with the exception of personal relationships. However, there were no changes in the levels of anxiety (p = 0.190) or depression (p = 0.682) at T3 compared to T0. Conclusions: Patients requiring IBC exhibit good treatment adherence, with a significant proportion of them performing self-catheterisation. After one year of IBC, a significant improvement in quality of life was noted, albeit with a significant impact on their daily lives and their personal and social relationships. Patient support programmes could be implemented to improve their ability to cope with difficulties and thus enhance both their quality of life and the maintenance of their adherence

The Helicobacter pylori Genome Project : insights into H. pylori population structure from analysis of a worldwide collection of complete genomes
Helicobacter pylori, a dominant member of the gastric microbiota, shares co-evolutionary history with humans. This has led to the development of genetically distinct H. pylori subpopulations associated with the geographic origin of the host and with differential gastric disease risk. Here, we provide insights into H. pylori population structure as a part of the Helicobacter pylori Genome Project (HpGP), a multi-disciplinary initiative aimed at elucidating H. pylori pathogenesis and identifying new therapeutic targets. We collected 1011 well-characterized clinical strains from 50 countries and generated high-quality genome sequences. We analysed core genome diversity and population structure of the HpGP dataset and 255 worldwide reference genomes to outline the ancestral contribution to Eurasian, African, and American populations. We found evidence of substantial contribution of population hpNorthAsia and subpopulation hspUral in Northern European H. pylori. The genomes of H. pylori isolated from northern and southern Indigenous Americans differed in that bacteria isolated in northern Indigenous communities were more similar to North Asian H. pylori while the southern had higher relatedness to hpEastAsia. Notably, we also found a highly clonal yet geographically dispersed North American subpopulation, which is negative for the cag pathogenicity island, and present in 7% of sequenced US genomes. We expect the HpGP dataset and the corresponding strains to become a major asset for H. pylori genomics
