Published: March 2022

Introducción: el síndrome HELLP históricamente se ha considerado una complicación grave de la preeclampsia, cuyo tratamiento consiste en la estabilización inmediata de la embarazada y el parto. Sin embargo, en pacientes que no responden al tratamiento, la plasmaféresis podría ser considerada una opción terapéutica. El objetivo de este artículo es presentar un caso clínico de una paciente con síndrome HELLP con requerimiento de plasmaféresis y revisar la literatura disponible por considerarse de relevancia clínica.Presentación del caso: paciente de 17 años, primigestante con síndrome HELLP, y requerimiento de plasmaféresis, por ausencia de respuesta al tratamiento. Se revisaron como fuentes de información la historia clínica y la búsqueda de la literatura científica con los términos "HELLP syndrome" “Plasmapheresis” “Treatment“en la base de datos PubMed, sin límite de tiempo; se incluyeron artículos originales, reportes y series de casos.Discusión: el síndrome HELLP se presenta entre el 0.5-0.9% de todas las gestaciones y hasta en un 20% en pacientes con preeclamsia. El tratamiento de primera línea es el parto inmediato, dado que la prolongación del embarazo se ha asociado con un aumento de la mortalidad materna y perinatal; sin embargo en pacientes con síndrome HELLP que no responden al tratamiento habitual dentro de las 24 a 72 horas posteriores al diagnóstico la plasmaféresis es una estrategia terapéutica indicada.Conclusión: la plasmaferesis es una opción de tratamiento que mejora los desenlaces de morbi-mortalidad materna y perinatal, no obstante faltan ensayos clínicos que permitan evaluar el impacto de la plasmaféresis en las gestantes.

Published: March 2022

Introduction

The societal changes triggered by the COVID-19 pandemic and resultant lockdowns have the potential to alter the incidence and nature of injuries within affected populations. We aimed to investigate these changes within Metropolitan London and the impact lockdown had on London's Air Ambulance's (LAA) response to incidents.

Methods

This retrospective cohort study compared data from all LAA missions in the two-month period following instigation of the 1st UK national lockdown in 2020 to the equivalent period in 2019. Patient demographics, nature and severity of injuries, incident details and LAA mission parameters were assessed.

Results

LAA saw a significant reduction in the mean (standard deviation) of activations per week under lockdown (32.75 [4.95] versus 54.25 [4.53], p<0.001). The distribution of patients across different trauma aetiologies differed significantly under lockdown, with proportionately more injuries resulting from domestic violence (0.7% versus 3.8%) and deliberate self-harm (DSH [16.5% versus 12.4%]), although the absolute number of DSH fell. Significantly fewer incidents occurred in central areas of London, but injury severity was unaffected by lockdown. After adjustment for confounders, lockdown was associated with shorter drive times, but not overall response times. There was no association between lockdown and aetiology or severity of injuries.

Conclusion

The COVID-19 pandemic and ensuing UK national lockdown had a substantial impact on major trauma patterns within London and the subsequent LAA response. The feared rise in suicide was not observed, but there was a notable increase in domestic violence frequency.
Rampas de Escape para Camiones en Carreteras: Un Nuevo Procedimiento para Justificar su Necesidad y Estimar su Ubicación
Authors: García-Ramírez Yasmany
Published: March 2022

Los conductores de camiones en pendientes descendentes pronunciadas pueden perder el control del vehículo por sobrecalentamiento del sistema de frenos. Ante esta posibilidad, las rampas de escape para camiones ayudan a detener esos vehículos errantes, reduciendo la fatalidad y daños materiales. La AASHTO presenta recomendaciones sin mostrar un procedimiento analítico para justificar su necesidad o estimar su ubicación. En Chile, se propuso un procedimiento, sin embargo, tiene ciertas limitaciones de aplicación y actualización; por lo tanto, el objetivo de este estudio es proponer un nuevo procedimiento para justificar la necesidad de las rampas de escape para camiones en carreteras y estimar su ubicación. Este procedimiento incluye las recientes actualizaciones del Sistema de Calificación de Peligrosidad de la Pendiente (GSRS por sus siglas en inglés). El sistema GSRS permite estimar la velocidad máxima de descenso seguro en una pendiente en descenso. Se explica el nuevo procedimiento mediante un ejemplo detallado de cálculo. El procedimiento propuesto resuelve las limitaciones del propuesto en Chile y completa las recomendaciones dadas por la AASHTO. Además, ofrece una base teórica, de fácil aplicación, para países en donde aún no se han construido este tipo de infraestructuras.
El Análisis Probabilístico de Seguridad como Método para Evaluar el Diseño de Sistemas Instrumentados de Seguridad de un Irradiador de Cobalto- 60 (Categoría IV)
Authors: Montaluisa Diego , Villacis William
Published: March 2022

El Departamento de Ciencias Nucleares de la Escuela Politécnica Nacional del Ecuador cuenta en sus instalaciones con un Irradiador de Cobalto-60. Este irradiador de categoría IV se instaló en el año 1975 y desde su inicio esta instalación cuenta con rigurosos protocolos de operación, seguridad radiológica y mantenimiento. Debido a los antiguos sistemas de control, el personal del departamento ha desarrollado nuevos diseños para los sistemas de instrumentos de seguridad. La evaluación del diseño de estos se realizó con la metodología de análisis probabilístico de seguridad. Esta evaluación incluyó algunos sistemas instrumentados de seguridad para determinar si los diseños desarrollados cumplen con los requisitos de seguridad radiológica establecidos por organismos internacionales como el Organismo Internacional de Energía Atómica y el Consejo Internacional de Protección Radiológica. El presente estudio ha considerado el proyecto de recarga del irradiador Cobalt-60 hasta una actividad de 50 000 Ci. Adicionalmente, en este estudio se ha priorizado los sistemas instrumentados de seguridad relacionados con el evento inicial la pérdida de blindaje húmedo (pérdida de agua en la piscina), que puede derivar en una sobreexposición del POE. Además, para la evaluación del punto de exposición, se ha optado por uno cercano al blindaje húmedo con un escenario hipotético de que ocurrió una pérdida total de agua; esta situación podría suceder durante un terremoto moderado. Al considerar el evento mencionado, se ha evaluado esta condición por medio de la metodología APS y se logró obtener como resultado que la probabilidad de ocurrencia anual para una sobreexposición superior a 2000 mSv para el POE es de 9,91E-8, este resultado se encuentra por debajo del límite establecido por la Comisión Internacional de Protección Radiológica para estos eventos.

Published: March 2022

El presente estudio tiene como objetivo evaluar la calidad del agua de la acequia Tilipulo Enríquez mediante la Relación de Absorción de Sodio (RAS) como indicador y así determinar si es apta o no para el riego de cultivos tomando como referencia las Normas Riverside. Para lo cual, se tomaron muestras en tres puntos del cantón Latacunga y uno de Saquisilí : Tanicuchí, Guaytacama, Saquisilí y Poaló. Se obtuvo como resultado que en el punto de muestreo 1 perteneciente a Tanicuchí, el agua es de buena calidad y apta para el riego, debido a que presenta fallas geológicas con pendientes entre 5 y 25%, además de que en esta zona del río Yanayacu aporta agua a la acequia aumentando su cauce y disminuyendo la conductividad del recurso hídrico, favoreciendo la calidad del agua. Además, al comparar estos resultados con Guaytacama (punto 2) y Saquisilí (punto 3) las aguas son utilizables para el riego con precauciones, ya que, estos territorios presentan pendientes entre 5 y 12%, un clima con temperaturas entre 12 a 15°C y precipitaciones entre 400 a 500 mm factores que contribuyen al aumento de conductividad y la salinidad de sus aguas. Por último, en el punto 4 de muestreo ubicado en Poaló el agua es de buena calidad y apta para el riego, pues esta zona es húmeda lluviosa y presenta mayor caudal lo cual incide principalmente en la disminución de la conductividad y concentración de sodio. Finalmente, este estudio en la acequia Tilipulo Enríquez puede aportar para futuras investigaciones, soluciones para la prevención y cuidado del agua de esta acequia.

Published: March 2022

En este estudio se llevó a cabo la investigación para determinar el potencial de los nanofluidos como fluidos caloportadores no convencionales en colectores solares en un país con tanto potencial térmico como Panamá. Luego de hacer la investigación preliminar sobre cuatro posibles fluidos caloportadores, encontramos que los nanofluidos de CuO, Al2O3, SiO2 y TiO2 con agua como fluido base poseen propiedades térmicas de gran interés. Después se realizó la simulación de un sistema de colector solar simple a través del software TRNSYS y se utilizaron las condiciones climáticas de Panamá. Se utilizó un intercambiador de calor de contraflujo para suministrar el agua caliente sanitaria a una residencia estándar de cuatro personas, donde cada una consume 50 litros diarios. Se logró comprobar que los nanofluidos son fluidos caloportadores más eficientes que el fluido convencional (agua), siendo el SiO2 el mejor nanofluido a la hora de escoger el intercambiador de calor que vaya a utilizarse, por lo que estos fluidos caloportadores no convencionales podrían ser posibles sustitutos para nuevos colectores en un futuro.

Published: March 2022

Objectives

Parameters of left ventricular (LV) mechanics, obtained from speckle-tracking echocardiography (STE), were found to be of prognostic value in patients with heart failure and those who underwent cardiac surgery. This study aimed to assess the value of STE in patients scheduled to undergo surgical ventricular restoration (SVR).

Methods

A total of 158 consecutive patients with baseline STE who underwent SVR due to an LV anteroapical aneurysm were included in the analysis. Preoperative longitudinal STE parameters were evaluated for their association with an outcome, defined as all-cause mortality, LV assist device implantation, or heart transplantation. The echocardiographic follow-up to assess the change in the regional function of the segments remote from the aneurysm was performed in 43 patients at a median of 10 months [interquartile range (IQR): 6–12.7 months] after SVR.

Results

During a median follow-up of 5.1 years (IQR: 1.6–8.7 years), events occurred in 68 patients (48%). Less impaired mean basal end-systolic longitudinal strain (BLS) with a cutoff value ≤ −10.1 % demonstrated a strong association with event-free survival, also in patients with an LV shape corresponding to an intermediate shape between aneurysmal and globally akinetic. Initially hypo- or akinetic basal segments with preoperative end-systolic strain ≤ −7.8% showed a greater improvement in wall motion at the short-term follow up.

Conclusion

Patients with less impaired preoperative BLS exhibited a better event-free survival after SVR, also those with severe LV remodeling. The preserved preoperative segmental longitudinal strain was associated with a greater improvement in regional wall motion after SVR. BLS assessment may play a predictive role in patients with an LV anteroapical aneurysm who are scheduled to undergo SVR.
What Do Peer Evaluations Represent? A Study of Rater Consensus and Target Personality
Authors: Martin Chris C. , Locke Kenneth D.
Published: March 2022

When professors assign group work, they assume that peer ratings are a valid source of information, but few studies have evaluated rater consensus in such ratings. We analyzed peer ratings from project teams in a second-year university course to examine consensus. Our first goal was to examine whether members of a team generally agreed on the competence of each team member. Our second goal was to test if a target’s personality traits predicted how well they were rated. Our third goal was to evaluate whether the self-rating of each student correlated with their peer rating. Data were analyzed from 130 students distributed across 21 teams (mean team size = 6.2). The sample was diverse in gender and ethnicity. Social relations model analyses showed that on average 32% of variance in peer-ratings was due to “consensus,” meaning some targets consistently received higher skill ratings than other targets did. Another 20% of the variance was due to “assimilation,” meaning some raters consistently gave higher ratings than other raters did. Thus, peer ratings reflected consensus (target effects), but also assimilation (rater effects) and noise. Among the six HEXACO traits that we examined, only conscientiousness predicted higher peer ratings, suggesting it may be beneficial to assign one highly conscientious person to every team. Lastly, there was an average correlation of.35 between target effects and self-ratings, indicating moderate self-other agreement, which suggests that students were only weakly biased in their self-ratings.
Review Writing as Part of the Doctoral Qualification Process in Theses-By-Publication. Results of an Interview Study With Ph.D. Students in German Sports Science
Authors: Jaitner David , Gabriel Lena , Zander Benjamin
Published: March 2022

Although review writing is becoming increasingly relevant for theses-by-publication processes, the topic of review writing has hardly been empirically studied from the Ph.D. students’ perspective. This paper addresses this desideratum by providing results of an exploratory study on review writing in German sports science. Based on a social constructivist approach and a socialization theory frame, the study investigated complexes of themes and knowledge that characterize Ph.D. students‘ review writing as part of sports science doctoral qualification processes within theses-by-publication. Between January and March 2021, 20 Ph.D. students from different sports science subdisciplines were interviewed using expert interviews. A structured-thematic qualitative content analysis identified six main experiential fields of review writing (type of review, individual significance of the review in the doctoral process, approach to writing the review, acquisition of review writing as a method, opportunities in elaborating and publishing the review, and challenges in elaborating and publishing the review). The topics of the category system highlight the diversity of review writing experiences, which can be bundled as content-related, social, and affective dimensions of socialization processes. At the same time, the topics of the category system allow specifying three dimensions of the socialization process for (sports) scientific qualification processes. In this way, the perspective of Ph.D. students on review writing as a central scientific practice and part of the doctoral dissertation is fundamentally determined. This could represent a gain in knowledge for the future implementation of research projects on the doctoral culture within as well as outside of sports science.

Published: March 2022

Objective

To compared the incidence rates and clinical features of precocious girls before and during the COVID-19 pandemic among Shanghai school-aged girls, and explored the potential mechanisms.

Methods

This cross-sectional study collected medical data about precocious girls between 2016 and 2020 from Shanghai Children’s Medical Center. Data of inpatient precocious girls from March to August in 2016-2019 (n=246) and 2020 (n=237) were collected. Subjects with abnormal brain and pituitary gland MRI reports, other endocrine diseases or chronic diseases were excluded. Finally, 209 precocious girls were included in the 2016-2019 group and 191 precocious girls were include in the 2020 group. Monthly incidence rates and clinical features were compared between before and during the COVID-19 pandemic. Linear regression models were used to examine the associations between biomarkers to explore the potential mechanisms.

Results

Monthly incidence rates of precocious puberty in outpatient girls from March to December 2020 (0.44-1.36%) and in inpatient girls from March to August 2020 (27.04-47.83%) were higher than those in 2016-2019 (0.30-0.52% and 10.53-18.42%, respectively). Serum concentrations of GnRH were higher in the 2020 group than in the 2016-2019 group (2.81 vs 1.99 mg/L). Serum concentrations of MKRN3 (1.02 vs 1.93 ng/ml) and ghrelin (0.38 vs 0.88 ng/ml) were lower in the 2020 group than in the 2016-2019 group. Moreover, the serum concentration of ghrelin was positively associated with the serum concentration of MKRN3 [β=0.891 (95% CI, 0.612, 1.171); p<0.001].

Conclusions

These findings suggest an increased incidence of precocious puberty during the COVID-19 pandemic among Shanghai school-aged girls, which may be associated with decreased serum concentrations of MKRN3 and ghrelin, and indicated ghrelin as a potential regulatory mechanism of puberty.
Extracellular Vesicles and Interleukins: Novel Frontiers in Diagnostic and Therapeutic for Cancer
Authors: Souza Aline G. , Colli Leandro M.
Published: March 2022

Tumor cells present many strategies for survival and dissemination in the tumor environment. Extracellular vesicles are a vital pathway used in crosstalk between tumor and non-malignant cells. They carry different types of molecules that, when internalized by target cells, can activate signaling pathways and molecular processes that will promote and disseminate neoplastic cells. Proteins, nucleic acids, and different cytokines, such as interleukins, are the main classes of molecules carried by extracellular vesicles and are being studied to understand the molecular mechanisms present in the tumor microenvironment. In particular, although poorly understood, the association between EVs and interleukins has revealed potential approaches to the diagnosis and therapeutics of several neoplasms.

Wild animals are captured or taken opportunistically, and the meat, body parts, and/or eggs are consumed for local subsistence or used for traditional purposes to some extent across most of the world, particularly in the tropics and subtropics. The consumption of aquatic animals is widespread, in some places has been sustained for millennia, and can be an important source of nutrition, income, and cultural identity to communities. Yet, economic opportunities to exploit wildlife at higher levels have led to unsustainable exploitation of some species. In the literature, there has been limited focus on the exploitation of aquatic non-fish animals for food and other purposes. Understanding the scope and potential threat of aquatic wild meat exploitation is an important first step toward appropriate inclusion on the international policy and conservation management agenda. Here, we conduct a review of the literature, and present an overview of the contemporary use of aquatic megafauna (cetaceans, sirenians, chelonians, and crocodylians) in the global tropics and subtropics, for species listed on the Appendices of the Convention on the Conservation of Migratory Species of Wild Animals (CMS). We find that consumption of aquatic megafauna is widespread in coastal regions, although to varying degrees, and that some species are likely to be at risk from overexploitation, particularly riverine megafauna. Finally, we provide recommendations for CMS in the context of the mandate of the Aquatic Wild Meat Working Group.
Hemisynapse Formation Between Target Astrocytes and Cortical Neuron Axons in vitro
Authors: Teng Zenghui , Gottmann Kurt
Published: March 2022

One of the most fundamental organizing principles in the mammalian brain is that neurons do not establish synapses with the other major cell type, the astrocytes. However, induced synapse formation between neurons and astrocytes appears conceivable, because astrocytes are well known to express functional ionotropic glutamate receptors. Here, we attempted to trigger synapse formation between co-cultured neurons and astrocytes by overexpressing the strongly synaptogenic adhesion protein LRRTM2 in astrocytes physically contacted by cortical axons. Interestingly, control experiments with immature cortical astrocytes without any overexpression resulted in the induction of synaptic vesicle clustering in contacting axons (hemisynapse formation). This synaptogenic activity correlated with the endogenous expression of the synaptogenic protein Neuroligin1. Hemisynapse formation was further enhanced upon overexpression of LRRTM2 in cortical astrocytes. In contrast, cerebellar astrocytes required overexpression of LRRTM2 for induction of synaptic vesicle clustering in contacting axons. We further addressed, whether hemisynapse formation was accompanied by the appearance of fully functional glutamatergic synapses. We therefore attempted to record AMPA receptor-mediated miniature excitatory postsynaptic currents (mEPSCs) in innervated astrocytes using the whole-cell patch-clamp technique. Despite the endogenous expression of the AMPA receptor subunits GluA2 and to a lesser extent GluA1, we did not reliably observe spontaneous AMPA mEPSCs. In conclusion, overexpression of the synaptogenic protein LRRTM2 induced hemisynapse formation between co-cultured neurons and astrocytes. However, the formation of fully functional synapses appeared to require additional factors critical for nano-alignment of presynaptic vesicles and postsynaptic receptors.

Background

Current reference systems using body mass index (BMI) or BMI z-scores to estimate overweight and obesity risk in adolescents are complex to use. An easy and effective measure and cutoffs such as the tri-ponderal mass index (TMI) are in need for parents and grassroots health workers.

Objective

The aim of this study was to test whether cohort-derived TMI could be efficient for obesity prediction and to find out whether simplified TMI cutoffs could be used in the prediction.

Methods

Data were obtained from a 12-year retrospective growth cohort generated in Guangdong, China. A total of 17,815 children (53.9% were boys) with 151,879 follow-ups conducted annually between 2005 and 2016 were involved. Late adolescent overweight and obesity were defined based on the BMI z-score (WHO 2007 growth reference) of the last measurement, which happened at the mean age of 17.2 (SD: 0.7) for both sexes. Analysis of the area under the curve (AUC) of the receiver operating characteristic curves was used to find the most appropriate cutoff.

Results

In total, 9,604 boys and 8,211 girls were included in the final analysis. TMI cutoffs performed better than WHO BMI cutoffs in the prediction of late adolescent overweight and obesity, with all corresponding AUCs <0.7. The simplified TMI cutoffs used to predict late adolescent overweight and obesity were 13.1 and 14.1 kg/m3 for children aged 7 to 15 years, respectively, with the corresponding AUCs ranging from 0.7315 (standard error, SE: 0.0132) to 0.9367 (SE: 0.0052). The cutoffs for predicting late adolescent overweight and obesity for children aged 16 to 18 years were 14.0 and 15.8 kg/m3, respectively, with the corresponding AUCs ranging from 0.9189 (SE: 0.0048) to 0.9841 (95% CI: 0.0027).

Conclusion

Tri-ponderal mass index with the ease of administration in practice could be a promising alternative screening tool to BMI for the prediction of late adolescent overweight and obesity.

In West Africa, kidney diseases are frequently seen, but diagnostic and therapeutic options are poor due to limited access to specialized facilities. To unravel the etiology and develop clinical guidelines, we collected clinical data and results of kidney biopsies in 121 pediatric and mostly young adult patients with edema and proteinuria in The Gambia. Workup included clinical examination, urine and serum analysis, and kidney biopsy findings. Selected cases were treated with steroids.

Results

The median age was 14.9 years (range 1.8–52.0) at presentation. The most frequent underlying histologies were post-infectious glomerulonephritis (PIGN) in 38%, focal-segmental glomerulosclerosis (FSGS) in 30%, minimal change nephrotic syndrome (MCNS) in 15%, and membranous glomerulonephritis (MGN) in 10% of cases. Patients with PIGN were significantly younger and had less proteinuria and higher serum albumin levels than the other three. Infected scabies was seen more often in cases with PIGN. Clinical parameters could not distinguish patients with FSGS, MCNS, and MGN. Steroid response was prompt in patients with MCNS (remission in 10/10 cases) compared to FSGS (4/19) and MGN (0/4). In summary, the clinical histopathological correlation allows a better approach to therapy and can be the basis for urgently needed interventional studies in steroid-resistant cases.

Bacterial blight (BB) of rice caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the most serious bacterial diseases that hinder the normal growth and production of rice, which greatly reduces the quality and yield of rice. The effect of traditional methods such as chemical control is often not ideal. A series of production practices have shown that among the numerous methods for BB controlling, breeding and using resistant varieties are the most economical, effective, and environmentally friendly, and the important basis for BB resistance breeding is the exploration of resistance genes and their functional research. So far, 44 rice BB resistance genes have been identified and confirmed by international registration or reported in journals, of which 15 have been successfully cloned and characterized. In this paper, research progress in recent years is reviewed mainly on the identification, map-based cloning, molecular resistance mechanism, and application in rice breeding of these BB resistance genes, and the future influence and direction of the remained research for rice BB resistance breeding are also prospected.

Achieving a high quality of life is dependent upon how individuals face adversity. Positive psychological interventions are well-suited to support coping efforts; however, experimental research is limited. The purpose of the current research was to examine whether different savoring interventions could increase important coping resources (i.e., positive emotions) in response to a social-evaluative hassle. We completed an experimental mixed subject design study with a university student sample. All participants completed a hassle induction task and were then randomly assigned into different intervention groups. Positive emotion ratings were collected at three points in time (baseline, post-induction task, post-intervention). Results revealed a significant time x intervention interaction effect, such that individuals in the savoring the moment intervention reported higher levels of positive emotions (at post-intervention) compared to individuals assigned to the true control group, guided imagery control group, and savoring through reminiscence intervention. Such findings represent a significant extension to savoring theory and offer support for savoring the moment exercises as a primary prevention strategy to bolster effective responses to social-evaluative hassles.
