Heart Rate Variability and Firstbeat Method for Detecting Sleep Stages in Healthy Young Adults: Feasibility Study
Authors: Kuula Liisa , Pesonen Anu-Katriina 
Published: December 2020

Background
Polysomnography (PSG) is considered the only reliable way to distinguish between different sleep stages. Wearable devices provide objective markers of sleep; however, these devices often rely only on accelerometer data, which do not enable reliable sleep stage detection. The alteration between sleep stages correlates with changes in physiological measures such as heart rate variability (HRV). Utilizing HRV measures may thus increase accuracy in wearable algorithms.

Objective
We examined the validity of the Firstbeat sleep analysis method, which is based on HRV and accelerometer measurements. The Firstbeat method was compared against PSG in a sample of healthy adults. Our aim was to evaluate how well Firstbeat distinguishes sleep stages, and which stages are most accurately detected with this method.

Methods
Twenty healthy adults (mean age 24.5 years, SD 3.5, range 20-37 years; 50% women) wore a Firstbeat Bodyguard 2 measurement device and a Geneactiv actigraph, along with taking ambulatory SomnoMedics PSG measurements for two consecutive nights, resulting in 40 nights of sleep comparisons. We compared the measures of sleep onset, wake, combined stage 1 and stage 2 (light sleep), stage 3 (slow wave sleep), and rapid eye movement (REM) sleep between Firstbeat and PSG. We calculated the sensitivity, specificity, and accuracy from the 30-second epoch-by-epoch data.

Results
In detecting wake, Firstbeat yielded good specificity (0.77), and excellent sensitivity (0.95) and accuracy (0.93) against PSG. Light sleep was detected with 0.69 specificity, 0.67 sensitivity, and 0.69 accuracy. Slow wave sleep was detected with 0.91 specificity, 0.72 sensitivity, and 0.87 accuracy. REM sleep was detected with 0.92 specificity, 0.60 sensitivity, and 0.84 accuracy. There were two measures that differed significantly between Firstbeat and PSG: Firstbeat underestimated REM sleep (mean 18 minutes, P=.03) and overestimated wake time (mean 14 minutes, P<.001).

Conclusions
This study supports utilizing HRV alongside an accelerometer as a means for distinguishing sleep from wake and for identifying sleep stages. The Firstbeat method was able to detect light sleep and slow wave sleep with no statistically significant difference to PSG. Firstbeat underestimated REM sleep and overestimated wake time. This study suggests that Firstbeat is a feasible method with sufficient validity to measure nocturnal sleep stage variation.

Актуальность. Хорошо спланированная и обоснованная дооперационная подготовка является важным инструментом снижения риска периоперационных осложнений. Европейским обществом кардиологов (ESC, 2014) и Европейским обществом анестезиологов (ESA, 2018) опубликованы рекомендации по подготовке пациента с сопутствующей кардиальной патологией к некардиальным операционным вмешательствам. Однако в нашу клиническую практику данные рекомендации имплементированы недостаточно. Целью нашей работы было проанализировать рутинную дооперационную подготовку пациента и выявить моменты, которые можно приблизить к рекомендованным стандартам с целью снижения периоперационных сердечно-сосудистых осложнений. Материалы и методы. Мы проанализировали 242 истории болезни пациентов, поступивших на плановое стационарное хирургическое лечение. Была проанализирована дооперационная подготовка с учетом клинических кардиальных факторов риска и факторов риска оперативного вмешательства. Результаты. Пациентам проведены стандартные обследования согласно установленным правилам. У всех пациентов зарегистрированы показатели электрокардиограммы, 47 % больным проведена эхокардиография покоя, 3 % выполнен тропониновый тест. С учетом интерполяции рекомендаций ESC и ESA на нашу выборку определение функциональной способности было целесообразным у 167 человек (69 %) с последующими оценкой клинических кардиальных факторов риска и определением необходимости проведения неинвазивных стресс-тестов лицам высокого риска возникновения инфаркта мио­карда и сердечной смерти. Кардиальные биомаркеры было целесообразно определить у 44 пациентов (18 %), регистрировать показатели электрокардиограммы покоя — у 127 пациентов (53 %), а эхокардиографии покоя — у 38 лиц (16 %). Такая тактика требует налаживания коммуникации между амбулаторным и стационарным звеньями медицинской системы. Выводы. Дооперационная подготовка большинства пациентов происходит в течение 24–48 часов после госпитализации в хирургическое отделение. Мы не используем определение функциональной способности пациента, не применяем шкалы оценки риска, не проводим неинвазивные стресс-тесты, недостаточно определяем кардиальные биомаркеры. Однако чаще проводим рутинные обследования, которые не являются решающими в данной клинической ситуации. В современных условиях наши клиники имеют достаточно ресурсов для внедрения рекомендаций ESC и ESA в клиническую практику.

Authors: Legnani Claudio , Borgo Enrico , Macchi Vittorio , Ventura Alberto 
Published: December 2020

Aim:
To compare the outcomes of patients who underwent autograft tenodesis with those who underwent allograft tenodesis for the treatment of chronic mechanical ankle instability.
Patients & methods:
Ten patients who underwent allograft lateral tenodesis were compared with 15 patients who underwent lateral tenodesis using a split peroneus brevis tendon. Patients were followed up after an average time of 10.5 years.
Results:
No statistically significant differences concerning American Orthopaedic Foot and Ankle Society and Karlsson–Peterson scores were reported (p = n.s.). A reduced average radiographic anterior talar translation was observed in the autograft group compared with the allograft group (1.4 and 4.0 mm respectively, p < 0.001).
Conclusion:
Both surgical techniques significantly improved subjective and objective outcomes in patients suffering from chronic ankle instability compared with pre-operatory status. Autograft stabilization provided reduced post-operative anterior talar translation compared with allograft tenodesis.

Published: December 2020

Considerando a prática curatorial como um espaço de poder e de disputas narrativas, apresento um relato crítico sobre o processo curatorial que culminou na exposição Pequenos gestos: memórias disruptivas,realizada entre outubro de 2019 e abril de 2020, no MAC-PR em Curitiba. Nesse sentido, reflito sobre os desafios, as possibilidades, os impasses e os limites de uma prática curatorial comprometida com os processos de decolonização do museu diante de uma coleção, constituída ao longo de quase cinco décadas, que conta com mais de 1.800 obras, majoritariamente de artistas – homens brancos – da região sul/sudeste. AbstractConsidering curatorial practice as a place of power and narratives dispu-te, we present a critical account of the curatorial process that culminated in the exhibition Small gestures: disruptive memories, held between October 2019 and April 2020, at MAC-PR at Curitiba. In this sense, we are interested in reflecting on what were the challenges, the possibilities, the impasses and the limits of a curatorial practice committed to the museum’s decolonization processes in the face of a collection created over almost five decades and which has more than 1,800 works, mostly by artists, whites man, from the south / southeast region.
A virada curatorial: da prática ao discurso
Authors: O’Neill Paul 
Published: December 2020

O artigo discute em termos históricos e teóricos o desenvolvimento da curadoria, a partir dos anos 1960, como uma atividade que passa a englobar uma dimensão discursiva e criadora, sobretudo em mostras coletivas e temporárias, notadamente bienais e megaexposições. O discurso crítico sobre a obra de arte como objeto autônomo se desdobra em uma modalidade de crítica curatorial, em que a exposição e o conjunto de obras no contexto expositivo adquirem primazia em relação aos objetos de arte em si. Contudo, argumenta o autor, a crítica curatorial respondeu com uma separação do gesto artístico e curatorial – sendo que tais divisões não são mais aparentes na prática das exposições contemporâneas. AbstractThis paper discusses in historical and theoretical terms the development of curatorship, since the 1960s, as an activity that starts to encompass a discursive and creative dimension, especially in group and temporary shows, notably biennials and mega exhibitions. The critical discourse about the work of art as an autonomous object unfolds in a modality of curatorial criticism, in which the exhibition and the set of works in the exhibition context take precedence over the objects of art itself. However, the author argues, curatorial criticism responded with a separation of artistic and curatorial gestures – when such divisions are no longer apparent in the practice of contemporary exhibitions.
Da crítica genética à crítica de processo: a teoria dos processos de criação e suas interfaces com a crítica de arte
Authors: Alves Lindomberto Ferreira 
Published: December 2020

O artigo procura examinar os percursos teóricos da crítica de processos criativos (de base semiótica), desde a emergência da crítica genética à sua expansão via crítica de processo. Partindo de uma revisão de caráter historiográfico, pretende-se, aqui, discutir até que ponto os efeitos produzidos pelos desafios em torno dos estudos que privilegiam a análise crítica dos processos de criação foram permitindo, ao longo de meio século, a elaboração de instrumentos teóricos capazes de acompanhar a complexa rede de interações engendradas pelo ato criador. Por fim, busca-se refletir sobre as possibilidades de atualização da crítica de arte na contemporaneidade, a partir de alguns aspectos que atravessam a análise dos objetos artísticos a partir de uma crítica de seus processos de criação.AbstractThe article seeks to examine the theoretical paths of creative process criticism (semiotic based), from the emergence of genetic criticism to its expansion via process criticism. Starting from a review of historiographic character, it is intended here to discuss to what extent the effects produced by the challenges around the studies that privilege the critical analysis of the creation processes were allowing, for half a century, the elaboration of theoretical instruments able to follow the complex networking of interactions engendered by the creative act. Finally, we seek to reflect on the possibilities of updating the art criticism in contemporary times from some aspects that intersect the analysis of artistic objects from a critique of their creative processes.
Imagens e desapagamento da história colonial francesa. Em torno da exposição Argélia 1830-1962 (Paris, Museu do Exército, 2012)
Authors: Denis Sébastien 
Published: December 2020

ResumoA exposição Argélia 1830-1962, realizada no Museu do Exército (Paris, França), em 2012, por ocasião do cinquentenário do fim da guerra da Argélia, permitiu refletir sobre o papel das imagens na reconfiguração da história das relações franco-argelinas. Para a instituição militar, e para os três curadores da exposição (incluindo o autor destas linhas), tratava-se de “libertar” o tratamento público destes 132 anos de história para construir pontes atuais entre os antigos protagonistas da história colonial e seus contemporâneos, e entre as duas margens do Mediterrâneo. Pela primeira vez, uma instituição nacional francesa encarava a colonização da Argélia como um todo, entre 1830 e 1962, procurando não omitir nada – especialmente a violência inerente à colonização. Résumé L'exposition Algérie 1830-1962, qui s'est tenue au Musée de l'Armée (Paris, France) en 2012 à l'occasion du cinquantenaire de la fin de la guerre d'Algérie, a été l'occasion d'une réflexion sur le rôle des images dans une reconfiguration de l'histoire des relations franco-algériennes. Il s'agissait pour l'institution militaire, et pour les trois commissaires de l'exposition (dont l'auteur de ces lignes), de « libérer » le traitement public de ces 132 ans d'histoire pour lancer des ponts entre les anciens acteurs de l'histoire coloniale et leurs contemporains, et entre les deux côtés de la Méditerranée aujourd'hui. Pour la première fois, une institution nationale française prenait à bras le corps la colonisation de l'Algérie comme un tout, entre 1830 et 1962, en tâchant de ne rien omettre - en particulier la violence inhérente à la colonisation.

Published: December 2020

OBJECTIVE
To investigate the impact of coronavirus disease 2019 lockdown on glycemic control and associated factors in people living with type 1 diabetes.

RESEARCH DESIGN AND METHODS
An observational evaluation from a self-reported questionnaire on behavioral changes and glycemic information from flash glucose monitoring (FGM) during the lockdown in 1,378 individuals living with type 1 diabetes who used a French dedicated nationwide web application (CoviDIAB).

RESULTS
The main outcome was the change of the mean glucose level 2 months before and 1 month after the lockdown. We found that mean glucose improved from 9.1 ± 1.7 mmol/L to 8.7 ± 1.7 mmol/L (P &lt; 0.001). Factors associated with better glycemic control were a decrease of alcohol consumption (odds ratio [OR] 1.75 [95% CI 1.04–2.94]), an increase in the frequency of FGM scans (OR 1.48 [1.04–2.10]) and in the number of hypoglycemia events (OR 1.67 [1.13–2.46]), and an easier diabetes control perception (OR 1.71 [1.18–2.49]).

CONCLUSIONS
Our findings suggest that lockdown has a positive impact on glycemic control in people with type 1 diabetes.

OBJECTIVE
Real-time continuous glucose monitoring (rtCGM) in critically ill hospitalized patients holds promise; however, real-world data are needed.

RESEARCH DESIGN AND METHODS
We placed Dexcom G6 CGM on intensive care unit (ICU) patients at Montefiore Medical Center with confirmed coronavirus disease 2019 (COVID-19) infection and glycemic variability. We analyzed inpatient CGM accuracy using point-of-care (POC) glucose–CGM matched pairs and included patients for analysis regardless of clinical status.

RESULTS
We included 11 patients with CGM: 8 on continuous insulin infusion (CII), 8 on vasopressors, 8 intubated, 4 on high-dose glucocorticoids, 6 on renal replacement therapy, and 2 with anasarca. Accuracy was 12.58% for mean and 6.3% for median absolute relative difference. CGM reduced POC testing by ∼60% for patients on CII.

CONCLUSIONS
In this real-world preliminary analysis of rtCGM during critical illness, we demonstrate early feasibility, considerable accuracy, and meaningful reduction in the frequency of POC glucose testing.

SIMULATION-BASED LEARNING IN RELIGIOUS EDUCATION TO DEVELOP STUDENT EMPATHY ON PEACE EDUCATION
Authors: Musnandar Aries 
Published: December 2020

Abstract

This study proposes an effective learning model to increase the quality of students’ empathy through simulation-based learning. The student’s noble behaviour as the objective religious subject in schools can be reached by fostering empathy. But, conservative teaching techniques such as lecturing, presentation and one-way communication are used by most teachers. In contrast, the simulation based-learning model for religious education could involve the affective domain which is appropriate to be used for behaviour change. Peace education in religious education subjects can be elaborated proportionally using simulation based-learning for developing the empathy of student as an important factor to have better peace education results. By using qualitative method, author conducted interview, observation and literature review for further analysis of this study. Research results confirmed that teacher who apply simulation based learning as a suitable method to enhance empathy for elevated tolerant behavior of students which is in line with peace education view.

Comparative Study of Plasmas Obtained by Femtosecond Laser Pulses Ablation in Si and SiO2
Authors: Torchia Gustavo A. , Alvira Fernando 
Published: December 2020

We analyzed the ablation dynamics for Silicon atoms located in two different environments. Experiments were done with semiconductor (silicon wafer) and a dielectric material (fused silica). We point out some difference in plasma dynamics for Silicon in both environments. Those results can not be explained with current and accepted theoretical models, which asseverate that after the femtosecond laser pulse interact with the surface, the process evolve as metal regardless the kind of material under excitation. Electronic density and temperature were measured with temporal resolution on SiO2 and Si samples by using standard fs LIBS imaging spectroscopy. Extinction time of both plasmas is different depending on the kind of sample under irradiation. Lifetime for plasma obtained in dielectric sample is shorter than that of semiconductor. The main reason to explain this behavior is related to the deep defect induced in the dielectric (fused silica) gap by the femtosecond process; these centers act as sink for the free electron promoted by the laser interaction from the valence band to the plasma, so for dielectrics, shorter lifetime plasmas are obtained when femtosecond pulse irradiation is conducted.
