    Acute kidney injury; Creatinine; Point-of-careLesión renal aguda; Creatinina; Punto de atenciónLesió renal aguda; Creatinina; Punt d'atencióBackground and aims GEM Premier ChemSTAT is a new point-of-care system providing rapid creatinine, BUN and tCO2 measurements together with electrolytes, metabolites, hematocrit, pH and pCO2 from a single whole blood specimen in acute care settings such as emergency departments and intensive care units. Accurate measurements of whole blood creatinine can aid in the diagnosis and treatment of renal diseases. Materials and methods Heparinized whole blood samples from different clinical locations were evaluated on the GEM Premier ChemSTAT and results compared to plasma from the same samples on the Beckman AU5800 or whole blood on the GEM Premier 4000. Precision studies were conducted with whole blood and quality control material. Results ChemSTAT correlated well with plasma samples on the AU5800 (regression slopes (S): 0.957–1.159, correlation coefficients (r)≥0.952) and with whole blood specimens on the GEM Premier 4000 (S: 0.9646–1.124, r ≥ 0.974). The repeatability was 0.1%–3.1% and QC precision were within lab and manufacturers’ specifications. Conclusion ChemSTAT demonstrated strong correlation to the comparative methods and excellent precision. Combining with its continuous quality management, ChemSTAT is suitable for acute care settings to provide rapid, reliable results, which could minimize time-to-treatment and improve patient outcome

    NASA (Network for Astronomy School Education) was created in the General Assembly of IAU in Rio de Janeiro in 2009. Its purpose was to train teachers in the teaching of astronomy using cheap and easy to obtain materials. So that this area could be instructed in an interactive way with the help of workshops designed by specialists in the field. Formally speaking, NASE courses start in 2010, with some pilot courses occurring in 2009, in Panama they begin in 2011. Ten years after the start of NASE Panama, we present a hindsight analysis, with the objective of letting others know its condition and the experience that has grown in science teachers, specifically in astronomy. From its beginning until now our country has had a total of 12 editions, 27 trained instructors, and more than 200 educators in different regions.NASE (Network for Astronomy School Education) se constituyó en la Asamblea General de la IAU en Río de Janeiro en 2009 con el propósito de entrenar docentes en la enseñanza de la astronomía usando materiales baratos y fáciles de conseguir para lograr una enseñanza más interactiva esto a través de diversos talleres diseñados por expertos en el área.  Formablemente los cursos NASE comienzan a dictarse a partir del 2010, aunque en el 2009 se realizaron algunos cursos pilotos, en Panamá estos cursos comienzan a dictarse a partir del 2011.

    Background: Sexual risk behaviors associated with poor information on sexuality have contributed to major public health problems in the area of sexual and reproductive health in teenagers and young adults in Colombia. Objective: To report our experience with the use of DoctorChat Mobile to provide sexual education and information among university students in Bogota, Colombia, and knowledge about the sexual risk factors detected among them. Methods: A mobile app that allows patients to ask about sexual and reproductive health issues was developed. Sexual and reproductive risk behaviors in a sample of young adults were measured before and after the use of the app through the validated survey Family Health International (FHI) Behavioral Surveillance Survey (BSS) for Use With Adults Between 15 and 49 Years. A nonprobabilistic convenience recruitment was undertaken through the study´s webpage. After completing the first survey, participants were allowed to download and use the app for a 6-month period (intervention), followed by completion of the same survey once again. For the inferential analysis, data was divided into 3 groups (dichotomous data, discrete quantitative data, and ordinal data) to compare the results of the questions between the first and the second survey. The study was carried out with a sample of university students between 18 and 29 years with access to mobile phones. Participation in the study was voluntary and anonymous. Results: A total of 257 subjects met the selection criteria. The preintervention survey was answered by 232 subjects, and 127 of them fully answered the postintervention survey. In total, 54.3% (69/127) of the subjects completed the survey but did not use the app, leaving an effective population of 58 subjects for analysis. Of these subjects, 53% (31/58) were women and 47% (27/58) were men. The mean age was 21 years, ranging between 18 and 29 years. The differences between the answers from both surveys were not statistically significant. The main sexual risk behaviors identified in the population were homosexual intercourse, nonuse of condoms, sexual intercourse with nonregular and commercial partners, the use of psychoactive substances, and lack of knowledge on symptoms of sexually transmitted diseases and HIV transmission. Conclusions: Although there were no differences between the pre- and postintervention results, the study revealed different risk behaviors among the participating subjects. These findings highlight the importance of promoting high-impact educational strategies on this matter and the importance of providing teenagers and young adults with easily accessible tools with reliable health information, regardless of their socioeconomic status

    Creatinine; Urea; Clinical chemistryCreatinina; Urea; Química clínicaCreatinina; Urea; Química clínicaThe aim of this study was to determine reference intervals in an outpatient population from Vall d’Hebron laboratory using an indirect approach previously described in a Dutch population (NUMBER project). We used anonymized test results from individuals visiting general practitioners and analysed during 2018. Analytical quality was assured by EQA performance, daily average monitoring and by assessing longitudinal accuracy between 2018 and 2020 (using trueness verifiers from Dutch EQA). Per test, outliers by biochemically related tests were excluded, data were transformed to a normal distribution (if necessary) and means and standard deviations were calculated, stratified by age and sex. In addition, the reference limit estimator method was also used to calculate reference intervals using the same dataset. Finally, for standardized tests reference intervals obtained were compared with the published NUMBER results. Reference intervals were calculated using data from 509,408 clinical requests. For biochemical tests following a normal distribution, similar reference intervals were found between Vall d’Hebron and the Dutch study. For creatinine and urea, reference intervals increased with age in both populations. The upper limits of Gamma-glutamyl transferase were markedly higher in the Dutch study compared to Vall d’Hebron results. Creatine kinase and uric acid reference intervals were higher in both populations compared to conventional reference intervals. Medical test results following a normal distribution showed comparable and consistent reference intervals between studies. Therefore a simple indirect method is a feasible and cost-efficient approach for calculating reference intervals. Yet, for generating standardized calculated reference intervals that are traceable to higher order materials and methods, efforts should also focus on test standardization and bias assessment using commutable trueness verifiers

    A Chirality-Based Quantum Leap

    There is increasing interest in the study of chiral degrees of freedom occurring in matter and in electromagnetic fields. Opportunities in quantum sciences will likely exploit two main areas that are the focus of this Review: (1) recent observations of the chiral-induced spin selectivity (CISS) effect in chiral molecules and engineered nanomaterials and (2) rapidly evolving nanophotonic strategies designed to amplify chiral light-matter interactions. On the one hand, the CISS effect underpins the observation that charge transport through nanoscopic chiral structures favors a particular electronic spin orientation, resulting in large room-temperature spin polarizations. Observations of the CISS effect suggest opportunities for spin control and for the design and fabrication of room-temperature quantum devices from the bottom up, with atomic-scale precision and molecular modularity. On the other hand, chiral-optical effects that depend on both spin- and orbital-angular momentum of photons could offer key advantages in all-optical and quantum information technologies. In particular, amplification of these chiral light-matter interactions using rationally designed plasmonic and dielectric nanomaterials provide approaches to manipulate light intensity, polarization, and phase in confined nanoscale geometries. Any technology that relies on optimal charge transport, or optical control and readout, including quantum devices for logic, sensing, and storage, may benefit from chiral quantum properties. These properties can be theoretically and experimentally investigated from a quantum information perspective, which has not yet been fully developed. There are uncharted implications for the quantum sciences once chiral couplings can be engineered to control the storage, transduction, and manipulation of quantum information. This forward-looking Review provides a survey of the experimental and theoretical fundamentals of chiral-influenced quantum effects and presents a vision for their possible future roles in enabling room-temperature quantum technologies.ISSN:1936-0851ISSN:1936-086

    Signaling and Sensory Adaptations in Weakly Electric Fish

    No full text
    In recent decades, neuroscience research has become largely dependent on a few “model organisms” (e.g. Drosophila melanogaster, Mus musculus). A holistic understanding of nervous systems requires study of a diversity of species and should consider the ecological context under which behaviors and their neural underpinnings evolved. My dissertation used a multidisciplinary and comparative phylogenetic approach to study signaling and sensory traits in a clade of weakly electric fishes, providing a more robust foundation for a burgeoning model in neuroscience. Gymnotiformes is a speciose and ecologically diverse order of Neotropical fish. These mostly nocturnal fishes generate electric organ discharges (EODs) to communicate with other electric fishes and to navigate and detect objects in dark waters. Previous studies in three species showed that melanocortin hormones can regulate the ion channels in the electrogenic cells (electrocytes) and modify EOD waveform properties such as amplitude and duration. In the first study, I describe variation in electric signaling behavior in response to adrenocorticotropic hormone (ACTH) in 21 species. Responses to ACTH varied greatly, suggesting there are species-specific differences in how melanocortins regulate electric signaling. Only species from the Hypopomidae and Sternopygidae consistently showed increases in EOD amplitude; however, individuals from species in all five families showed some form of waveform modulation. The second study examined the effects of ACTH at the level of electrocyte membranes, compared ion channel distributions in two representative species, and described the kinetics of a sodium channel in a unique monophasic species, Brachyhypopomus bennetti. B. bennetti showed significantly less EOD plasticity relative to biphasic congeners. Sodium channels in this species were unexpectedly detected on both electrocyte membranes, and I determined that a second action potential reduces the EOD amplitude. The final study describes variation in the dimensions and distributions of electroreceptor pores on the heads of seven species. In some species, I found unique electroreceptor distributions associated with specialized feeding strategies, suggesting species habitat use influences electroreceptor organization. Together, these studies highlight the value of gymnotiforms as excellent models for studying the pleiotropic functions of melanocortin hormones, ion channel evolution, and the role of ecology in shaping specialized sensory systems
