Published: September 2021

Background: Personal protective equipment (PPE) is an essential component of safely treating suspected or confirmed SARS-CoV-2 patients. PPE acts as a barrier to heat loss, therefore increasing the risk of thermal strain which may impact on cognitive function. Healthcare workers (HCWs) need to be able to prioritize and execute complex tasks effectively to ensure patient safety. This study evaluated pre-cooling and per-cooling methods on thermal strain, thermal comfort and cognitive function during simulated emergency management of an acutely unwell patient.Methods: This randomized controlled crossover trial was run at the Clinical Services Department of the Medical Research Unit The Gambia. Each participant attended two sessions (Cool and Control) in standard PPE. Cool involved pre-cooling with an ice slurry ingestion and per-cooling by wearing an ice-vest external to PPE.Results: Twelve participants completed both sessions. There was a significant increase in tympanic temperature in Control sessions at both 1 and 2 h in PPE (p = 0.01). No significant increase was seen during Cool. Effect estimate of Cool was −0.2°C (95% CI −0.43; 0.01, p = 0.06) post 1 h and −0.28°C (95% CI −0.57; 0.02, p = 0.06) post 2 h on tympanic temperature. Cool improved thermal comfort (p &lt; 0.001), thermal sensation (p &lt; 0.001), and thirst (p = 0.04). No difference on cognitive function was demonstrated using multilevel modeling.Discussion: Thermal strain in HCWs wearing PPE can be safely reduced using pre- and per-cooling methods external to PPE.

Background: Emergency rooms (ERs) overcrowded by older adults have been the focus of public health policies during the recent COVID-19 outbreak too. This phenomenon needed a change in the nursing care of older frail people. Health policies have tried to mitigate the frequent use of ER by implementing community care to meet the care demands of older adults. The present study aimed to investigate the predictors of emergency room access (ERA) and not-urgent emergency room access (NUERA) of community-dwelling frail older adults in order to provide an indication for out-of-hospital care services.Method: Secondary analysis of an observational longitudinal cohort study was carried out. The cohort consisted of 1,246 community-dwelling frail older adults (over 65 years) in the Latium region in Italy. The ER admission rate was assessed over 3 years from the administration of the functional geriatric evaluation (FGE) questionnaire. The ordinal regression model was used to identify the predictors of ERA and NUERA. Moreover, the ERA and NUERA rate per 100 observations/year was analyzed.Results: The mean age was 73.6 (SD ± 7.1) years, and 53.4% were women. NUERAs were the 39.2% of the ERAs; robust and pre-frail individuals (79.3% of the sample) generated more than two-third of ERAs (68.17%), even if frails and very frails showed the higher ER rates per observation/year. The ordinal logistic regression model highlighted a predictive role on ERAs of comorbidity (OR = 1.13, p &lt; 0.001) and frailty level (OR = 1.29; p &lt; 0.001). Concerning NUERAs, social network (OR 0.54, P = 0.015) and a medium score of pulmo-cardio-vascular function (OR 1.50, P = 0.006) were the predictors.Conclusion: Comorbidity, lack of social support, and functional limitations increase both ERA and NUERA rates generated by the older adult population. Overall, bio-psycho-social frailty represents an indicator of the frequency of ERAs. However, to reduce the number of ERAs, intervention should focus mainly on the robust and pre-frail needs for prevention and care.
Thermospheric Neutral Winds as the Cause of Drift Shell Distortion in Earth’s Inner Radiation Belt

Published: September 2021

Recent analysis of energetic electron measurements from the Magnetic Electron Ion Spectrometer instruments onboard the Van Allen Probes showed a local time variation of the equatorial electron intensity in the Earth’s inner radiation belt. The local time asymmetry was interpreted as evidence of drift shell distortion by a large-scale electric field. It was also demonstrated that the inclusion of a simple dawn-to-dusk electric field model improved the agreement between observations and theoretical expectations. Yet, exactly what drives this electric field was left unexplained. We combine in-situ field and particle observations, together with a physics-based coupled model, the Rice Convection Model (RCM) Coupled Thermosphere-Ionosphere-Plasmasphere-electrodynamics (CTIPe), to revisit the local time asymmetry of the equatorial electron intensity observed in the innermost radiation belt. The study is based on the dawn-dusk difference in equatorial electron intensity measured at L = 1.30 during the first 60 days of the year 2014. Analysis of measured equatorial electron intensity in the 150–400 keV energy range, in-situ DC electric field measurements and wind dynamo modeling outputs provide consistent estimates of the order of 6–8 kV for the average dawn-to-dusk electric potential variation. This suggests that the dynamo electric fields produced by tidal motion of upper atmospheric winds flowing across Earth’s magnetic field lines - the quiet time ionospheric wind dynamo - are the main drivers of the drift shell distortion in the Earth’s inner radiation belt.
Narrow-Line Seyfert 1 Galaxies With Absorbed Jets–Insights From Radio Spectral Index Maps
Authors: Järvelä Emilia , Berton Marco , Crepaldi Luca 
Published: September 2021

Narrow-line Seyfert 1 (NLS1) galaxies are active galactic nuclei (AGN) believed to be in the early stages of their evolution. A fraction of them have been found to host relativistic jets. Due to the lack of large-scale diffuse radio emission they are believed to be experiencing one of their first activity cycles, and can offer us an opportunity to study the early evolution of more powerful AGN, such as radio galaxies and flat-spectrum radio quasars. Recently, a group of intriguing jetted NLS1s was discovered: based on high radio frequency data they host relativistic jets, but in the JVLA observations they all showed steep radio spectra at least up to 9.0 GHz, indicating very strong absorption at these frequencies. In this paper we study a subset of these sources in detail by employing spatially resolved radio spectral index maps at central frequencies of 1.6, 5.2, and 9.0 GHz. With spectral index maps we can disentangle the different radio emission components over the radio-emitting region, and get insights into the production mechanisms of radio emission. In addition, we study their host galaxies in relation to the radio emission to investigate if the host can provide us additional information regarding the origin of the radio emission, or the launching mechanism of the jets. It is fascinating how different the sources studied are, and certainly more, especially wide frequency-range, and high-resolution observations will be needed to understand their history and current properties, such as the reason behind the extraordinary radio spectra.

The aim of this research was to evaluate the changes in the mechanical properties of poly(butylene adipate co-terephthalate)/poly(lactic acid) (PBAT/PLA) polymeric blend after the radiation process at different radiation doses. The irradiation was performed in an electron beam accelerator, with 1.5 MeV of energy and 25 mA electric current. The samples were irradiated with doses of 5, 10, 15, 25, 50, 65 and 80 kGy. Both irradiated and non-irradiated samples were characterized by Izod pendulum impact resistance and tensile strength at rupture. The results showed an increase of 44% in relation to Izod impact resistance at a dose of 65 kGy. However, the module of elasticity decreased 56% and tensile strength at rupture decreased 55% at the same radiation dose. In relation to elongation, significant alterations caused by electron beam irradiation was not observed. Therefore, it can be concluded that irradiated blends could be used to make environmentally friendly products, which could absorb impact energy.

The complexities associated with healthcare centres have made conflict a part and parcel of their operational milieus. Student nurses on formal clinical training, being part of the system, are not resistant to the deleterious outcomes of such conflicts. Thus, this is study assessed conflict dynamics and management strategies of student nurses in government hospitals in Adamawa State, Nigeria. A descriptive survey design was adopted and a sample of 160 student nurses was selected through random sampling technique. A self-structured questionnaire titled “Student Nursing Conflict Questionnaire” (SNCQ) was used to elicit primary data. Data collected were analysed with frequency counts, percentage and standard deviation. The study discovered that the majority of student nurses frequently encountered conflict (50.6%) in hospitals and they often perceived it as something bad (70.6%). Also, the major types of conflict often experienced by student nurses were “nurse-student nurse conflict” (NSC) (36.9%) and “patient relatives-student nurse conflict” (PRSC) (36.9%). The main causes of these conflicts were lateness to the hospital ( = 3.375) and unclear definition of responsibilities between student nurses and other auxiliary health workers ( = 3.338). Furthermore, the main consequences of conflict on student nurses were lowering their productivity ( = 3.550) and discouraging effective training of student nurses ( = 3.569). The conflict management styles often adopted by student nurses were collaborating style ( =3.153) and accommodating style ( =3.025). Based on these findings, it was recommended that medical peace education should be promoted in all ramifications in health establishments in order to help those that wish to become health practitioners such as student nurses as well as those already practicing in the field to understand conflict behavioural dynamics for constructive mitigation to enhance their productivity and healthcare service delivery.

Published: September 2021

En el presente artículo se presentan los resultados del proyecto que tuvo como objetivo elaborar un nuevo tipo de papel artesanal a base de residuos agroindustriales, para comparar algunas de sus propiedades con el papel industrial. Los desechos agroindustriales se componen principalmente de tallos, raíces, hojas u otras partes de plantas como el bambú, el carrizo, el plátano, el agave, la piña, y el coco. Dichos residuos son apartados y clasificados como materiales “inútiles” y constituyen una fuente importante de contaminación. Resulta importante indicar que en los últimos años, ha existido una relación directa entre la acumulación excesiva de estos desechos con el incremento de la población humana, ya que se han tenido que destinar grandes cantidades de extensiones de tierra para el cultivo de frutas y vegetales para atender la demanda de alimentos de las personas. El desarrollo de este proyecto constó de 4 etapas, las cuales se obtuvieron al combinar la Metodología de Ecodiseño de la Sociedad Pública de Gestión Ambiental del Gobierno Vasco, IHOBE; y la Metodología de Desarrollo de Productos de Ulrich y Epigger, a las cuales se agregó una fase experimental. La Etapa 1 constó de toda la investigación de campo y bibliográfica que fue realizada para sustentar el proyecto, también se obtuvo el inventario del Ciclo de Vida del papel industrial. Posteriormente, en la Etapa 2 se utilizó el Método de Diseño de Experimentos para efectuar un conjunto de pruebas con distintas formulaciones de los componentes del papel artesanal, variando las proporciones de fibra y aditivo. En la Etapa 3 se definió el inventario del Ciclo de Vida del papel artesanal, además se determinó el diagrama de procesos de operación para su fabricación. Finalmente, en la Etapa 4 se realizaron un conjunto de pruebas físicas, además se compararon los inventarios del Ciclo de Vida y las características del nuevo papel artesanal y del papel industrial.

Los humedales artificiales son un reservorio construido en un terreno con paredes y pisos impermeabilizados que contienen un sustrato (grava o arena) y una vegetación acuática adecuada para tratar efluentes residuales. Esta tecnología utilizada para recuperar el recurso hídrico ha sido aplicada en países desarrollados y actualmente se está siendo implementada en países como Colombia por su bajos costos constructivos comparado con la tecnología convencional. El objetivo del presente estudio fue evaluar la eficiencia de un humedal de flujo subsuperficial horizontal construido en el Colegio Comfamiliar Siglo XXI, sede Campestre Corregimiento de San Fernando, Municipio de Pasto, Colombia. La valoración de la eficiencia se hizo mediante la medición y análisis de los parámetros DBO5, DQO, sólidos suspendidos totales, nitrógeno total, fósforo total, grasas y aceites, coliformes totales y Escherichia Coli. Los resultados fueron DBO5 93,89%, DQO 84,98% y SST 40%. El pretratamiento hizo que los parámetros nitrógeno y grasas no presentaran variación. En los parámetros microbiológicos Coliformes Totales y E. Coli, se obtuvieron eficiencias del 99,99 y 99,97% respectivamente. La calidad del agua luego de pasar por el humedal es óptima para realizar una descarga a un cuerpo receptor y también puede ser reutilizada para la agricultura según los resultados obtenidos.

Published: September 2021

This study evaluated the isolation, molecular typing and celular proliferation of C. perfringens in small intestine of cattle and sheep distributed in case and control groups. In the case group, out of the 61 bovine samples analyzed, C. perfringens was isolated in 29 (47.54%) and in 4 (33.34%) from 12 sheep samples. In the control group, we did not isolate the microorganism in the bovine samples (73 samples), however it was possible in 5 (20.83%) out of the 24 sheep samples. All isolates (100%) were classified as type A, and cell quantification showed that in control group, all cattle samples resulted in 10 CFU/g of intestinal content while in the study group presented a median value of 104 CFU/g, varying from 10 CFU/g through 108 CFU/g. In ovine group there was a clear divison of values between the two groups. Molecular typing corroborates with other studies regardin the epidemiological importance of type A in enterotoxaemia in ruminants, thus cellular quantification data allow us to conclude that healthy animals present a basal level of C. perfringens lower than 10 CFU/g that does not allow its isolation.
