Cyanobacteria produce exopolysaccharides (EPSs) as an adaptative mechanism against ultraviolet radiation and desiccation. Cellulose is present in the extracellular polymeric substance in some cyanobacteria genera and it has been proposed as a raw material for biofuel production. The goal of this work was to evaluate the cellulose presence in EPS of Atacama cyanobacteria strains and its use as an alternative and innovative biological source to produce bioethanol. The presence of cellulose was evaluated using techniques of molecular biology, bioinformatics, and electronic microscopy. The conserved motif D,D,D,35QXXRW, characteristic of processive β-glycosyltransferase in all cellulose-producing organisms, was identified in the genome of the LLA-10 strain. This is evidence that cellulose synthase in the LLA-10 strain is a functional enzyme. EPS from Atacama cyanobacteria was hydrolyzed by β-glucosidases (cellobiase and cellulase) and the released glucose was yeast-fermented to ethanol. Ethanol production reached 172.69 ± 0.02 mg ethanol/g EPS after 48 h of incubation. These results are the first step in the evaluation of EPS produced by native cyanobacteria isolated from northern Chile for future biotechnological applications such as the production of bioethanol.

Environmental burdens disproportionately impact the health of communities of color and low-income communities. Contemporary and legacy industry and land development may pollute soils with pesticides, petroleum products, and trace metals that can directly and indirectly impact the health of frontline communities. Past efforts to study environmental injustice have often excluded those most impacted, created distrust of researchers and other experts among frontline communities, and resulted in little to no structural change. Prevailing research methods value formal knowledge systems, while often dismissing the knowledge of those most harmed by environmental hazards. Community science has emerged as a process of doing science that centers the participation of community members, who may co-develop research questions, inform study methods, collect data, interpret findings, or implement projects. While community science is one of several research methods that can advance community goals, it can also be implemented in ways that are extractive or harm communities. Research on best practices for community science is robust; however, how community science has been used in urban soil research is not well understood. We identified sixteen relevant urban soil studies published between 2008 and 2021 that used community science methods or engaged with community members around soil pollution. We then assessed the selected studies using two community engagement models to better understand community engagement practices in urban soil pollution science. The Spectrum of Community Engagement to Ownership (SCEO) model, which organizes engagement from level 0 (ignore) to 5 (defer to) was used to assess all studies. Studies that explicitly aimed to co-develop research with the community were additionally assessed using the Urban Sustainability Directors Network High Impact Practices (USDN HIPs). The majority of the studies assessed were aligned with levels 1–3 of the SCEO. Studies assessed as levels 4–5 of the SCEO were associated with delegating power to communities, community engages decision-making, creating space for community voices, and remediation efforts. We propose that future urban remediation soil pollution work that engages at higher levels of the SCEO and employs USDN HIPs, will be more effective at addressing crucial environmental health challenges by supporting, equitable, inclusive, and sustainable solutions.

In this study, a quick microwave-based treatment was developed as a front end for DNA analysis of forensic samples. The effect of microwave treatment is to cause cell disruption which can improve the release of DNA during direct PCR as well as with extraction methods. Exposure to microwave preprocessing improved the quality of rapid genotyping, particularly when used with low level samples. Optimal results were obtained when samples were microwaved at 300W for 40 s, resulting in improved allele detection. Overall, the addition of this simple preprocessing step improves sensitivity and allele recovery for low level DNA samples when combined with expedited DNA analysis workflows. Its main advantages include speed, low cost, compatibility with downstream DNA methods and application to a wide variety of samples.

Introducción: La dieta mediterránea (DM) es reconocida como un patrón dietético sostenible y saludable; sin embargo, la adhesión de los estudiantes universitarios a sus recomendaciones es baja. El etiquetado nutricional es una estrategia para promover elecciones alimentarias saludables. El objetivo de este estudio fue analizar la asociación entre el uso del etiquetado nutricional, la adhesión a la DM y el estado nutricional determinado mediante la percepción de la imagen corporal en estudiantes universitarios chilenos. Metodología: Se realizó un estudio transversal, en el que participaron 286 estudiantes entre 18 y 29 años, matriculados en una universidad pública de Valparaíso, Chile. La adhesión a la DM se determinó mediante el Test KIDMED, la frecuencia de uso del etiquetado nutricional se consultó utilizando tres preguntas: ¿revisas la cantidad de sellos “Alto en” de los alimentos envasados antes de comprarlos?; ¿compras alimentos envasados con menos sellos “Alto en” para asegurar una elección saludable?; ¿lees el etiquetado nutricional de los alimentos envasados con sellos “Alto en” antes de comprarlos?. El estado nutricional se determinó mediante la percepción de la imagen corporal. La aplicación de los cuestionarios fue en línea. Se realizaron Modelos de Regresión Logística para evaluar la asociación entre las variables. Resultados: Cerca del 55% reportó un uso frecuente del etiquetado nutricional, el 26,2% una alta adhesión a la DM y el 51,4% se percibe con exceso de peso corporal. Los estudiantes que frecuentemente compran alimentos envasados con menos sellos “Alto en” y leen el etiquetado nutricional antes de comprar alimentos envasados tuvieron más probabilidad de reportar una alta adhesión a la DM (OR:2,39; IC 95%: 1,17-4,85 y OR:2,38; IC 95%: 1,20-4,73 respectivamente) que aquellos usuarios no frecuentes (p

Con el objetivo de evaluar la seguridad, aceptabilidad galénica y eficacia del preparado GV-328, actualmente comercializado como complemento dietético, para el tratamiento de la lesión aftosa en los niños, se diseñó un estudio abierto prospectivo, aprobado por el Comité Ético de Investigación Clínica (ODP-ECL-2017-01) de la Universitat International de Catalunya (UIC) y registrado en ClinicalTrials.gov (Identificador: NCT04677062). Todos los padres o tutores de los niños que participaron en el estudio dieron su consentimiento informado de manera voluntaria y escrita. El estudio cumple con los principios éticos en investigación médica en seres humanos establecidos en la Declaración de Helsinki (última actualización octubre 2013). Se incluyeron niños de entre 3 y 13 años atendidos en el Servicio de Odontopediatría de la Clínica Universitaria de Odontología de la UIC afectados por aftas bucales con un máximo de 48 h de evolución (excluyendo las lesiones múltiples o traumáticas y pacientes que estuvieran tomando medicación concomitante y los pacientes diabéticos)1. Todos fueron tratados con el preparado GV-328, en pastillas con ácido hialurónico y cinc, y un soporte de plástico para evitar que se trague de golpe2. Se disuelve lentamente con la saliva como si fuera un caramelo bucal, y actúa tópicamente en la zona afectada. Tanto el contenido en ácido hialurónico (5 mg/pastilla) como en cinc (1 mg/pastilla) pueden considerarse muy seguros para su uso en la población infantil3, 4. El tratamiento en estudio (entre 4 y 6 pastillas al día según la edad) se realizó durante 4 días. info:eu-repo/semantics/publishedVersion

Despite that piperacillin-tazobactam combination is commonly used in critically ill children, increasing evidence suggests that the current dosing schedules are not optimal for these patients. The aim of this work is to develop a population pharmacokinetic model for piperacillin to evaluate the efficacy of standard dosing in children with and without continuous kidney replacement therapy (CKRT) and to propose alternative dosing schemes maximizing target attainment.Four hundred twenty-nine piperacillin concentrations measured in different matrices, obtained from 32 critically ill children (19 without CKRT, 13 with CKRT) receiving 100 mg/kg of piperacillin/tazobactam every 8 hours (increased to 12 hours after the fourth dose) were modelled simultaneously using the population approach with NONMEM 7.4. The percentage of patients with 90% fT MIC and target attainment (percentage of dosing interval above MIC) were estimated for different intermittent and continuous infusions in the studied population.Piperacillin pharmacokinetic was best described with a two-compartment model. Renal, nonrenal, and hemofilter clearances were found to be influenced by the glomerular filtration rate, height (renal clearance), weight (nonrenal clearance), and filter surface (hemofilter clearance). Only seven (37%) children without CKRT and seven (54%) with CKRT achieved 90% fT MIC with the current dosing schedule. Of the alternative regimens evaluated, a 24-hour continuous infusion of 200 mg/kg (CKRT) and 300 mg/kg (no CKRT) provided 100% fT MIC (percent of time free drug remains above the minimum inhibitory concentration) (≤16 mg/L) and target attainments ≥90% across all evaluated MICs.In children with and without CKRT, standard dosing failed to provide an adequate systemic exposure, while prolonged and continuous infusions showed an improved efficacy.

Continuous incisional lidocaine infusion has been proposed as an adjunctive therapy in the management of postoperative pain in adult patients. The aim of this study was to determine the efficacy and safety of a continuous subcutaneous lidocaine infusion in pediatric patients following open heart surgery. All patients receiving a subcutaneous lidocaine infusion in median sternotomy incisions after open heart surgery during 2 consecutive years were included in the study. A historical cohort of patients was used as a control group. Demographic variables (age, size, and surgical procedure), variables related to sedation and analgesia (COMFORT and analgesia scales, drug doses, and duration), and complications were registered. 106 patients in the lidocaine infusion group and 79 patients in the control group were included. Incisional analgesia was effective for the treatment of pain as it reduced the dose and duration of intravenous fentanyl (odds ratio (OR) 6.26, confidence interval (CI) 95%: 2.48-15.97, p = 0.001 ; OR 4.30, CI 95%: 2.09-8.84, p = 0.001 , respectively). The reduction in fentanyl use was more important in children over two years of age. Adverse effects were seen in three children (2.8%): they all had decreased level of consciousness, and one of them presented seizures as well. Two of these three patients had lidocaine levels over 2 mcg/ml. A continuous lidocaine incisional infusion is effective for the treatment of pain after open heart surgery. This procedure reduced intravenous analgesic drug requirements in pediatric patients undergoing a median sternotomy incision. Although the incidence of secondary effects is low, monitoring of neurologic status and lidocaine blood levels are recommended in all patients.

Disparities persist in breast cancer outcomes between Latina survivors and non-Hispanic Whites. Identifying methods to ensure that Latinas participate in and benefit from translational behavioral medicine research is important to reduce disparities. We developed a “Social Network Research Registry” to enhance Latina survivors’ engagement in research and explored the social networks and research/cancer organization participation in this population. We initially recruited 30 Latina breast cancer survivors (“seeds”) from community organizations and identified other survivors through snowball sampling. Guided by Social Network Analysis, we assessed the structural (e.g., size) and functional (e.g., social support) characteristics of the network, willingness to join the registry, prior research participation, involvement in cancer organizations, and interest in different types of research and roles in research. The resulting network size was 98, including 53 women who enrolled in the study and 45 who were listed in the network but did not enroll. All enrolled participants (N = 53) agreed to be part of the registry. We identified 15 participants who occupied strategic positions as hubs and/or bridges. Women who were currently involved in cancer organizations were more likely to have participated in research (70.3% vs. 18.8%); χ(2) (1, 53) = 11.97, p = .001. Most were interested in surveys/interviews (98%), behavioral interventions (96%), and becoming health promoters (79%). The Social Network Research Registry is an acceptable and feasible strategy to engage underrepresented Latina survivors in research. Social network analysis can be useful to identify members who occupy key positions to enhance recruitment and translational efforts.

Aim The objective of this paper is to identify attribute patterns of influential individuals in intensive care units using unsupervised cluster analysis. Background Despite the acknowledgement that culture of an organisation is critical to improving patient safety, specific methods to shift culture have not been explicitly identified. Methods A social network analysis survey was conducted and an unsupervised cluster analysis was used. Results A total of 100 surveys were gathered. Unsupervised cluster analysis was used to group individuals with similar dimensions highlighting three general genres of influencers: well-rounded, knowledge and relational. Conclusions Culture is created locally by individual influencers. Cluster analysis is an effective way to identify common characteristics among members of an intensive care unit team that are noted as highly influential by their peers. To change culture, identifying and then integrating the influencers in intervention development and dissemination may create more sustainable and effective culture change. Additional studies are ongoing to test the effectiveness of utilising these influencers to disseminate patient safety interventions. Implications for nursing management This study offers an approach that can be helpful in both identifying and understanding influential team members and may be an important aspect of developing methods to change organisational culture.

Objective To design an experimental pediatric animal model of acute kidney injury induced by cisplatin. Methods Prospective comparative observational animal study in two different phases. Acute kidney injury was induced using three different doses of cisplatin (2, 3 and 5 mg/kg). The development of nephrotoxicity was assessed 2 to 4 days after cisplatin administration by estimating biochemical parameters, diuresis and renal morphology. Analytical values and renal morphology were compared between 15 piglets treated with cisplatin 3 mg/kg and 15 control piglets in the second phase of the study. Results 41 piglets were studied. The dose of 3 mg/kg administered 48 hours before the experience induced a significant increase in serum creatinine and urea without an increase in potassium levels. Piglets treated with cisplatin 3 mg/kg had significantly higher values of creatinine, urea, phosphate and amylase, less diuresis and lower values of potassium, sodium and bicarbonate than control piglets. Histological findings showed evidence of a dose-dependent increase in renal damage. Conclusions a dose of 3 mg/kg of cisplatin induces a significant alteration in renal function 48 hours after its administration, so it can be used as a pediatric animal model of non-oliguric acute kidney injury.

OBJECTIVE: Despite the benefits of hormonal therapy (HT) adherence remains suboptimal in ER positive breast cancer patients. Medication adherence is challenging to assess and tends to be overestimated. The Digital Health Feedback System (DHFS) consists of an ingestible sensor attached to a pill that sends intake date and time to a smart phone or computer. Patients can share this information with health care providers and other persons. The DHFS can also send reminders. This mixed methods study examined providers’ perceptions of HT medication adherence. The potential role of the DHFS in enhancing medication tracking and adherence was also explored. METHODS: We conducted semi-structured interviews with key informants (N=10). Questions examined perceptions about adherence barriers and facilitators, challenges tracking adherence, and views on the DHFS. Findings informed the development of a survey that was administered online (N=19). RESULTS: Providers emphasized the importance of fostering open and trustful communication around adherence. The most mentioned challenges to assessing adherence were the patient not disclosing discontinuation immediately (78.9%) and over-reporting adherence (57.9%). The perceived potential benefits of DHFS were the ability to track adherence better (94.7%) and reminders to take the medication (68.4%). Safety to ingest a sensor was as a major perceived barrier (8 4.2%). CONCLUSION: Interventions that target providers and doctor-patient communication are warranted to enhance adherence and reduce communication delays around HT discontinuation. PRACTICE IMPLICATIONS: DHFS has the potential to enhance HT adherence by directly targeting barriers. Future studies should also examine the feasibility of adopting the DHFS with cancer patients.

Las universidades tienen una responsabilidad social con la formación de profesionales. Mantener una estabilidad en su claustro constituye una necesidad, por cuanto garantiza los recursos humanos calificados para el logro de la calidad educacional e investigativa. En contradicción con esta condición, en América Latina y el Caribe se ha producido un incremento de la emigración calificada hacia países desarrollados, muchos de esos emigrantes procedentes de centros universitarios. Cuba no está exenta de este proceso, y ha sido incluida dentro de las corrientes de robo de cerebros. La Universidad de Oriente (UO), de Santiago de Cuba, presentó una movilidad creciente de su claustro entre los años 2004 y 2013, en la que las emigraciones al exterior tienen una incidencia considerable. Fue motivo de atención en el presente trabajo los factores que están asociados a este tipo de movilidad. Para la recogida de información se procesó estadísticamente la información contenida en las bases de datos de la universidad, al tiempo que se aplicaron entrevistas a informantes claves y a docentes de la misma que hayan emigrado. Se utilizaron, además, los datos recogidos en el cuestionario aplicado a docentes del claustro de dicha universidad por el proyecto donde se insertan las autoras. Se reveló la necesidad de prestar atención a factores que se relacionan con la emigración de profesionales en la UO tales como: condiciones socioeconómicas, políticas migratorias, sus insatisfacciones profesionales y condiciones laborales en su relación agente- estructura. Universities have a social responsibility with the formation of new professionals. Keeping stability on its staff is a must, since that guarantees the qualified human resources to achieve educational and research quality. In opposition to this condition, in Latin America and the Caribbean we found an increase in the emigration indicators of professionals to developed countries, many of them from the university centers. Cuba is not an exception, and it has been included inside the currents of brain robbery. The Oriente University, from Santiago de Cuba, showed an increasing staff mobility between the years 2004 and 2013, with a profound incidence of migration to other countries. A motive of attention in this work was the factors associated to that type mobility. For the collection of information that led to the theoretical analysis, we worked with the databases of the university, together with the application of key informant interviews and professors who have emigrated. Besides, we used the data gathered in the questionnaire prepared by the project in which the authors are inserted, answered by professors of the University. This investigation revealed the need to pay attention to factors relating to the migration of professionals in the UO such as: socioeconomic conditions, migratory policies, their professional dissatisfactions and working conditions in their agent-structure relation.

Valproic acid (VPA) is the most commonly used antiepileptic drug in pediatric patients, but its major drawback is its multiple pharmacological interactions. Objective To study children who had been simultaneously treated with carbapenems and valproic acid, considering drug levels, pharmacological interactions and clinical follow-up. Material and methods Retrospective study of children who simultaneously received treatment with VPA and carbapenems between January 2003 and December 2011. Demographic variables, indication of treatment, dose, VPA plasma levels, interactions, clinical manifestations and medical management were analyzed. Results 28 children with concomitant treatment with both drugs were included in the study. 64.3% were males. 78.6% of the interactions were observed in the Intensive Care Unit. 60.7% of children had been previously treated VPA and its major indication were generalized seizures. Basal plasma levels of VPA were recorded in 53% and at 24 h after admittance in 60%. “40% of basal VPA levels were below therapeutic range prior to the administration of carbapenem. After the introduction of carbapenem 88% of level determinations were below therapeutic range”. 54.5% of the patients that were chronically receiving VPA and had good control of epilepsy before admission had seizures during the coadministration. One patient that was on VPA before admission but with bad control of epilepsy worsened, and one patient that acutely received VPA did not achieve seizure freedom. In these cases it was necessary to either increase VPA dose or change to a different antiepileptic drug. Conclusions Little is known about the mechanism of pharmacologic interactions between carbapenems and VPA, but it leads to a reduction in plasma levels that may cause a loss of seizure control, so simultaneous use of both drugs should be avoided when possible. If not, VPA levels should be monitored.

- Abstract
Over the past few decades, the book series Linguistische Arbeiten [Linguistic Studies], comprising over 500 volumes, has made a significant contribution to the development of linguistic theory both in Germany and internationally. The series will continue to deliver new impulses for research and maintain the central insight of linguistics that progress can only be made in acquiring new knowledge about human languages both synchronically and diachronically by closely combining empirical and theoretical analyses. To this end, we invite submission of high-quality linguistic studies from all the central areas of general linguistics and the linguistics of individual languages which address topical questions, discuss new data and advance the development of linguistic theory.

Analysis of Social Networks may be further supported through the collection of ordinal data. Such data may help to determine potentially optimal teams extending across groups or departments through the use of Kruskal‘s Algorithm for the identification of Maximal Spanning Trees. Ordinal assessments of workers by those who have collaborated with them in the past may be aggregated into simple, stratified network visualizations to identify high performing members as well as those who may need re-training or reassignment. Contingency table analysis and the Gamma Test of Monotone Trend may provide further evidence supporting the identification of such individuals. Additionally, the Gamma Test offers a more powerful and informative alternative to the Chi-Squared Test of Independence. These methods stand out as an area for further research in practical settings and may be streamlined into existing research practices with great ease.

Abstract To evaluate the hemodynamic effects and the safety profile of fluid bolus resuscitation with hypertonic saline albumin (HSA) in critically ill children, we performed a prospective observational pilot study between October 2018 and May 2021 in the pediatric intensive care unit (PICU) in a tertiary hospital in Madrid, Spain. Sixty-four HSA boluses were analyzed in 23 patients. A mean volume of 5.7 ml/kg (Standard Deviation, SD 2.3 ml/kg) per bolus was infused. Acute hypotension was the main indication. 91% of the patients had a cardiac disease, 56% of them had undergone cardiac surgery in the previous 72 h, and 47.8% associated right ventricular dysfunction. A significant increase in systolic, mean, and diastolic blood pressure and a decrease in the vasoactive index was observed after the infusion of HSA. This effect lasted for twenty-four hours (p

Abstract A secondary analysis of a randomized study was performed to study the relationship between volumetric capnography (VCAP) and arterial CO2 partial pressure (PCO2) during cardiopulmonary resuscitation (CPR) and to analyze the ability of these parameters to predict the return of spontaneous circulation (ROSC) in a pediatric animal model of asphyxial cardiac arrest (CA). Asphyxial CA was induced by sedation, muscle relaxation and extubation. CPR was started 2 min after CA occurred. Airway management was performed with early endotracheal intubation or bag-mask ventilation, according to randomization group. CPR was continued until ROSC or 24 min of resuscitation. End-tidal carbon dioxide (EtCO2), CO2 production (VCO2), and EtCO2/VCO2/kg ratio were continuously recorded. Seventy-nine piglets were included, 26 (32.9%) of whom achieved ROSC. EtCO2 was the best predictor of ROSC (AUC 0.72, p < 0.01 and optimal cutoff point of 21.6 mmHg). No statistical differences were obtained regarding VCO2, VCO2/kg and EtCO2/VCO2/kg ratios. VCO2 and VCO2/kg showed an inverse correlation with PCO2, with a higher correlation coefficient as resuscitation progressed. EtCO2 also had an inverse correlation with PCO2 from minute 18 to 24 of resuscitation. Our findings suggest that EtCO2 is the best VCAP-derived parameter for predicting ROSC. EtCO2 and VCO2 showed an inverse correlation with PCO2. Therefore, these parameters are not adequate to measure ventilation during CPR.

AimsTo assess the impact of two different respiratory rates in hemodynamic, perfusion and ventilation parameters in a pediatric animal model of cardiac arrest (CA).MethodsAn experimental randomized controlled trial was carried out in 50 piglets under asphyxial CA. After ROSC, they were randomized into two groups: 20 and 30 respirations per minute (rpm). Hemodynamic, perfusion and ventilation parameters were measured 10 minutes after asphyxia, just before ROSC and at 5, 15, 30 and 60 minutes after ROSC. Independent medians test, Kruskal-Wallis test and χ2 test, were used to compare continuous and categorical variables, respectively. Spearman's Rho was used to assess correlation between continuous variables. A p-value ResultsArterial partial pressure of carbon dioxide (PaCO2) was significantly lower in the 30 rpm group after 15 minutes (41 vs. 54.5 mmHg, p ConclusionsThis animal model of asphyxial CA shows that a respiratory rate of 30 rpm is more effective to reach normoventilation than 20 rpm in piglets after ROSC. This ventilation strategy seems to be safe, as it does not cause hyperventilation and does not affect hemodynamics or cerebral tissue perfusion.

OBJECTIVE:To design an experimental pediatric animal model of acute kidney injury induced by cisplatin. METHODS:Prospective comparative observational animal study in two different phases. Acute kidney injury was induced using three different doses of cisplatin (2, 3 and 5 mg/kg). The development of nephrotoxicity was assessed 2 to 4 days after cisplatin administration by estimating biochemical parameters, diuresis and renal morphology. Analytical values and renal morphology were compared between 15 piglets treated with cisplatin 3 mg/kg and 15 control piglets in the second phase of the study. RESULTS:41 piglets were studied. The dose of 3 mg/kg administered 48 hours before the experience induced a significant increase in serum creatinine and urea without an increase in potassium levels. Piglets treated with cisplatin 3 mg/kg had significantly higher values of creatinine, urea, phosphate and amylase, less diuresis and lower values of potassium, sodium and bicarbonate than control piglets. Histological findings showed evidence of a dose-dependent increase in renal damage. CONCLUSIONS:a dose of 3 mg/kg of cisplatin induces a significant alteration in renal function 48 hours after its administration, so it can be used as a pediatric animal model of non-oliguric acute kidney injury.

- Abstract
Hemorrhagic shock is a leading cause of morbidity and mortality in pediatric patients. Interpretation of the clinical indicators validated in adults to guide resuscitation and comparison between different therapies is difficult in children due to the inherent heterogeneity of this population. As a result, compared to adults, appropriate management of pediatric hemorrhagic shock is still not well established. In addition, the scarcity of pediatric patients with hemorrhagic shock precludes the development of clinically relevant studies. For this reason, an experimental pediatric animal model is necessary to study the effects of hemorrhage in children as well as their response to different therapies. We present an infant animal model of volume-controlled hemorrhagic shock in anesthetized young pigs. Hemorrhage is induced by withdrawing a previously calculated blood volume, and the pig is subsequently monitored and resuscitated with different therapies. Here, we describe a precise and highly reproducible model of hemorrhagic shock in immature swine. The model yields hemodynamic data that characterizes compensatory mechanisms that are activated in response to severe hemorrhage.
