Friends and Foes: Conditional Occurrence Rates of Exoplanet Companions and Their Impact on Radial Velocity Follow-up Surveys
Authors: He Matthias Y. , Ford Eric B. , Ragozzine Darin
Published: October 2021

Population studies of Kepler's multiplanet systems have revealed a surprising degree of structure in their underlying architectures. Information from a detected transiting planet can be combined with a population model to make predictions about the presence and properties of additional planets in the system. Using a statistical model for the distribution of planetary systems, we compute the conditional occurrence of planets as a function of the period and radius of Kepler-detectable planets. About half (0.52 ± 0.03) of the time, the detected planet is not the planet with the largest semi-amplitude (K) in the system, so efforts to measure the mass of the transiting planet with radial velocity (RV) follow up will have to contend with additional planetary signals in the data. We simulate RV observations to show that assuming a single-planet model to measure the K of the transiting planet often requires significantly more observations than in the ideal case with no additional planets, due to systematic errors from unseen planet companions. Our results show that planets around 10 day periods with K close to the single-measurement RV precision (σ
1,obs) typically require ∼100 observations to measure their K to within 20% error. For a next generation RV instrument achieving σ
1,obs = 10 cm s−1, about ∼200 (600) observations are needed to measure the K of a transiting Venus in a Kepler-like system to better than 20% (10%) error, which is ∼2.3 times as many as would be necessary for a Venus without any planetary companions.

Abstract
 Fetal hydrothorax (FH) or pleural effusion is a clinical entity, and refers to accumulation of fetal pleural fluid, which may presents a wide spectrum of severity ranging from small, harmless effusion, to life-threatening thoracic compression (1). The perinatal mortality associated with pleural effusion is at least 50 %. Cardiac and extra-cardiac abnormalities may accompany the hydrothorax and their presence also affects the prognosis (2).
Division of the right atrium, first reported in 1868, also known as cor triatriatum dexter, is extremely a rare congenitally abnormality, in which persistence of right valve of the embryonic systemic venous sinus divides the right atrium into two chambers. The embryonic valvar structures, whose significance during fetal life is to direct the richly oxygenated inferior caval venous  blood across to the left atrium and thence to the aorta, normal regress in late fetal life and early childhood.
Cytomegalovirus (CMV) is a common human virus, member of herpes virus family, and the most common cause of intrauterine infection, occurring in 0.2 % to 2.2 % of life births (3,4). This report describes antenataly diagnosed a case of a divided right atrium, associated with severe form of hydrothorax and Cytomegalovirus infection.
Here we present a fetus with sever hydrothorax associated with divided right atrium and cytomegalovirus infection.
Génocide ouïghour : cheminement d’un projet colonial
Authors: Reyhan Dilnur
Published: October 2021

Le premier trimestre 2021, les parlements de sept pays occidentaux ont reconnu que la Chine mène un génocide contre les Ouïghours. Une résolution a été déposée avant l’été à l’Assemblée nationale en France dans ce sens. Que se passe-t-il entre l’État chinois et la population ouïghoure ? Pourquoi parle-t-on aujourd’hui de génocide ? Quel est le fond du conflit sino-ouïghour ? J’essaierai de répondre dans cet article à ces questions en expliquant le processus colonial mis progressivement en place qui s’est fortement aggravé au cours de ces dernières décennies et qu’on peut qualifier de développement totalitaire mariant parfaitement un système dictatorial de type « stalinien » et une économie capitaliste « sauvage » propre au régime chinois actuel. A partir de la théorie de « colonisation du peuplement » développée dans la dernière décennie, j’analyserai ici le cas de la Région ouïghoure afin de démontrer le processus du génocide en cours qui est le résultat d’un long projet colonial.
Le gouvernement fédéral américain au chevet de l’assurance santé
Authors: Beaussier Anne-Laure
Published: October 2021

Pour beaucoup d’observateurs des politiques de santé des États-Unis, les 28 millions de personnes restant privées d’assurance maladie en 2020, dix ans après l’adoption de l’Obamacare, la réforme du système de santé emblématique du premier mandat de Barack Obama, constituent une démonstration d’échec, appelant à une réforme de la réforme. L’Affordable Care Act (ACA) avait pourtant fait le pari qu’il était possible, avec les bons instruments réglementaires et incitatifs, non seulement de soutenir et de reconstruire un marché des assurances santé qui semblait au bord de l’explosion mais également de l’inciter à endosser des objectifs de service public et de bien commun. Dix ans plus tard cependant, les limites de la réforme, à la fois en termes de couverture de la population et en termes de maîtrise des dépenses de santé alimentent de nombreuses critiques. Cette contribution revient sur la stratégie suivie par l’ACA. Elle explicite ses principaux instruments, analyse les difficultés rencontrées lors de leur mise en œuvre et discute les alternatives envisagées aujourd’hui tant du côté démocrate que du côté républicain.
Bricoler une action municipale de santé à faible coût ou rebâtir des solidarités organisées ? Regard sur la diversité des « mutuelles communales »
Authors: Comer Clémentine
Published: October 2021

À partir du cas des « mutuelles communales », contrats de complémentaire santé à tarif préférentiel proposés par les élus locaux à leurs administrés, cet article examine l’élargissement à bas coût de l’intervention sociale des municipalités. Il rend en cela compte de bricolages et d’expérimentations de la part de pouvoirs publics locaux pourtant dépourvus de compétences en matière de couverture d’assurance maladie. Parce qu’il répond à un projet citoyen et social plus ou moins porté politiquement, s’insère dans les réseaux locaux d’acteurs de l’assurance, et rencontre une offre commerciale que se disputent mutuelles territoriales, réseaux de courtiers et grandes compagnies d’assurance, le déploiement des mutuelles communales donne à voir des configurations d’action publique contrastées, tant du point de vue de la portée solidaire des dispositifs que de leur pérennité économique.
Les interventions basées sur la pleine conscience et l’acceptation en sport : une revue de la littérature
Authors: Ben Salha Manel , Fournier Jean
Published: October 2021

En psychologie du sport, l’intérêt pour les interventions basées sur la pleine conscience et l’acceptation (Mindfulness and Acceptance Based Intervention, MABI) est en continuelle augmentation. Ces interventions semblent être une alternative ou un complément pour l’amélioration de la performance sportive. De ce fait, une bonne compréhension de l’application des MABI dans le contexte sportif permettrait de développer des interventions plus adaptées aux spécificités de la pratique sportive et d’élargir la base de connaissances dans ce domaine. La première partie de cette revue de littérature présente différentes interventions basées sur la pleine conscience et l’acceptation développées pour les sportifs. La deuxième partie décrit l’utilisation de la pleine conscience dans la pratique sportive et les mécanismes impliqués pour expliquer les liens entre la pleine conscience et les variables de la performance sportive. Finalement, la dernière partie présente les mesures de la pleine conscience développées pour les sportifs.
Experiential Learning Through a Dementia Simulation
Authors: Solecki Cathleen S. , Turkelson Carman L. , Harris Margaret A.
Published: October 2021

Health care providers do not always possess the knowledge and skills necessary to optimally manage behavioral symptoms in patients with Alzheimer's disease (AD). The purpose of the current project was to evaluate the use of a simulated virtual reality AD experience on nursing staff sensitivity, awareness, and perceptions of caring for patients with AD. A quasi-experimental design was used. The Long Tour Survey and Approaches to Dementia Questionnaire were administered pre and post simulation and the Perceptions of Caring surveys were administered 3 to 6 weeks post-intervention. Total scores, although not statistically significant, revealed a slight change in the total score and hope subscale, representing more optimism toward people with dementia. The virtual reality AD simulation was a beneficial experience but unable to demonstrate a real change for the majority of participants. [

The results show a high rate of collaboration between authors but somewhat scarce if considered by their work institutions, a significant increase in all the impact indicators consulted, and a reduction in the number of members of the editorial team. It is concluded that Materiales de Construcción journal has increased its internationality and considerably improved its impact between 2013 and 2020.
A desinformação no Brasil durante a pandemia de Covid-19:
Authors: Gehrke Marília , Benetti Marcia
Published: October 2021

Este artigo apresenta os principais temas, plataformas e atores envolvidos na disseminação de desinformação sobre a Covid-19 no Brasil. Analisamos 407 textos classificados como falsos pelas agências de fact-checking que integram a plataforma colaborativa Latam Chequea Coronavirus. O corpus se refere ao início da pandemia, e por isso inclui conteúdos publicados de 15 de março a 21 de julho de 2020. Por meio de análise de conteúdo, descobrimos que o tópico mais frequente é a política (25,55%), seguido de cura (20,64%), dados (19,66%) e contágio (18,43%). Em relação aos sentidos das publicações, obtidos por meio de análise qualitativa de 300 textos, identificamos que as principais narrativas buscam favorecer o presidente Jair Bolsonaro e suas convicções a respeito da pandemia. Praticamente a metade dos casos (48,34%) utiliza, como estratégia, a produção de falso contexto, quando uma imagem genuína ou um fato verdadeiro é deslocado de seu contexto original para gerar uma inverdade. Também estão no entorno do presidente os atores que com frequência espalham desinformação sobre a pandemia nas redes sociais digitais. Em 60 textos nos quais foi possível identificar os atores com potencial de ampliar a profusão de conteúdo falso, o deputado federal Osmar Terra se apresenta como uma figura central, ao lado de Bolsonaro e seus filhos. Nosso levantamento ainda mostra que a desinformação circula principalmente no Facebook e no WhatsApp, muitas vezes simultaneamente nesses espaços e em outras redes sociais. Texto e imagem são os formatos mais recorrentes.

Fissuras no Poder Algorítmico: plataformas, códigos e contestação
Authors: Ferrari Fabian , Graham Mark
Published: October 2021

Plataformas digitais de trabalho não tentam construir relações fortes e de confiança entre trabalhadores, clientes e plataforma. Em vez disso, as plataformas utilizam uma dupla articulação do poder algorítmico para governar forças de trabalho espacialmente dispersas em sentidos materiais e discursivos. Entretanto, os algoritmos não têm resultados hegemônicos e não retiram totalmente a agência dos trabalhadores das plataformas. Por meio de manipulação, subversão e ruptura, os trabalhadores trazem as fissuras desse poder algorítmico para sua ação. As fissuras no poder algorítmico são momentos em que os algoritmos passam a não governar como foi pretendido. Embora esses momentos não sejam resultados simples e positivos para os trabalhadores, eles mostram como o poder algorítmico é inerentemente apenas parcial.

Published: October 2021

Privacy protection is a hot topic in network security, many scholars are committed to evaluating privacy information disclosure by quantifying privacy, thereby protecting privacy and preventing telecommunications fraud. However, in the process of quantitative privacy, few people consider the reasoning relationship between privacy information, which leads to the underestimation of privacy disclosure and privacy disclosure caused by malicious reasoning. This paper completes an experiment on privacy information disclosure in the real world based on WordNet ontology .According to a privacy measurement algorithm, this experiment calculates the privacy disclosure of public figures in different fields, and conducts horizontal and vertical analysis to obtain different privacy disclosure characteristics. The experiment not only shows the situation of privacy disclosure, but also gives suggestions and method to reduce privacy disclosure.
Predicting Security-Vulnerable Developers Based on Their Techno-Behavioral Characteristics
Authors: Goonetillake M. D. J. S. , Jayashanka Rangana , Rathnayaka S. V.
Published: October 2021

Assigning developers for highly secured software projects requires identifying developers’ tendency to contribute towards vulnerable software codes called developer-centric security vulnerability to mitigate issues on human resource management, financial and project timelines. There are problems in assessing the previous codebases in evaluating the developer-centric security vulnerability level of each developer. Thus, this paper suggests a method to evaluate this through the techno-behavioral features of their previous projects. Consequently, we present results of an exploratory study of the developer-centric security vulnerability level prediction using a dataset of 1827 developers by logically selecting 13 techno-behavioral features. Our results depict that there is a correlation between techno-behavioral features and developer-centric security vulnerability with 89.46% accuracy. This model enables to predict developer-centric security vulnerability level of any developer if the required techno-behavioral features are available avoiding the analysis of his/her previous codebases.
An Ensemble Approach for Feature Selection and Classification in Intrusion Detection Using Extra-Tree Algorithm
Authors: Kharwar Ankit Rajeshkumar , Thakor Devendra V.
Published: October 2021

The number of attacks increased with speedy development in web communication in the last couple of years. The Anomaly Detection method for IDS has become substantial in detecting novel attacks in Intrusion Detection System (IDS). Achieving high accuracy are the significant challenges in designing an intrusion detection system. It also emphasizes applying different feature selection techniques to identify the most suitable feature subset. The author uses Extremely randomized trees (Extra-Tree) for feature importance. The author tries multiple thresholds on the feature importance parameters to find the best features. If single classifiers use, then the classifier's output is wrong, so that the final decision may be wrong. So The author uses an Extra-Tree classifier applied to the best-selected features. The proposed method is estimated on standard datasets KDD CUP'99, NSL-KDD, and UNSW-NB15. The experimental results show that the proposed approach performs better than existing methods in detection rate, false alarm rate, and accuracy.
Watermarking Images via Counting-Based Secret Sharing for Lightweight Semi-Complete Authentication
Authors: Gutub Adnan
Published: October 2021

Watermarking is the process of embedding specific data to prove ownership copyright authentication. It is needed whenever media-files are used without proper permission is granted. The current watermarking challenge comes from the ownership proof especially as slight tampering occurs on the multimedia-file which injure the watermarking causing difficulty in its copyright proof. This paper proposes utilizing counting-based secret sharing strategy to allow validation of ownership RGB watermarking even if some of the image-file is interfered. We validate image watermarking partially as lightweight semi-complete verification, which is not possible in the normal random-stream watermarking schemes. Although the work is still in its early stage, it is promising research showing real attractive contribution opportunities. The work is tested and compared to other strategies in aspects of robustness, capacity, and security, providing attractive remarks worth noting. The study evaluation results showed interesting contribution believed to be pioneering.
Adaptive Deep Rider LSTM-Enabled Objective Functions for RPL Routing in IoT Applications
Authors: Chaudhari D. A.  , Chaudhari Dipalee A. , Umamaheswari E.  , Umamaheswari E.
Published: October 2021

This paper presents a proposed Objective Function (OF) design using various routing metrics for improving the performance of IoT applications. The most important idea of the proposed design is the selection of the routing metrics with respect to the application requirements. The various metrics, such as Energy, Distance, Delay, Link quality, Trust (EDDLT) are used for improving the objective function design of the RPL in various IoT applications. Here, the Adaptive Deep rider LSTM is newly employed for the energy prediction where the Adaptive Deep Rider LSTM is devised by the combination of the adaptive theory with the Rider Adam Algorithm (RAA), and the Deep-Long Short Memory (Deep-LSTM). However, the evaluation of the proposed method is carried out energy dissipation, throughput, and delay by achieving a minimum energy dissipation of 0.549, maximum throughput of 1, and a minimum delay of 0.191, respectively.
The Environmental Effects of FDI
Authors: Pereira Vijay , Moosa Imad A. , Ramiah Vikash , Temouri Yama
Published: October 2021

Empirical work on the environmental effects of FDI has produced a mixed bag of results, with hardly any evidence for Middle East and North Africa (MENA) countries. A theoretical model is presented, postulating that whether FDI has a positive or negative effect on the environment depends on the position of the underlying country or region on the environmental Kuznets curve (EKC). The empirical results indicate that FDI leads to environmental degradation in MENA countries and that they fall on the rising sector of the EKC. The theoretical model is supported by the empirical results.
The geochemistry of thallium and its isotopes in rare-element pegmatites
Authors: Jacques I J , Anderson A J , Nielsen S G
Published: October 2021

The Tl isotopic and trace element composition of K-feldspar, mica, pollucite and pyrite from 13 niobium-yttrium-fluorine (NYF)-type and 14 lithium-cesium-tantalum (LCT)-type rare-element pegmatites was investigated. In general, the epsilon-205Tl values for
K-feldspar in NYF- and LCT-type pegmatites increases with increasing magmatic fractionation. Both NYF and LCT pegmatites display a wide range in epsilon-205Tl (-4.25 to 9.41), which complicates attempts to characterize source reservoirs. We suggest 205Tl-enrichment during pegmatite crystallization
occurs as Tl partitions between the residual melt and a coexisting aqueous fluid or flux-rich silicate liquid. Preferential association of 205Tl with Cl in the immiscible aqueous fluid may influence the isotopic character of the growing pegmatite minerals. Subsolidus alteration of K-feldspar by
aqueous fluids, as indicated by the redistribution of Cs in K-feldspar, resulted in epsilon-205Tl values below the crustal average (-2.0 epsilon-205Tl). Such low epsilon-205Tl values in K-feldspar is attributed to preferential removal and transport of 205Tl by Cl-bearing fluids during dissolution
and reprecipitation. The combination of thallium isotope and trace element data may be used to examine late-stage processes related to rare-element mineralization in some pegmatites. High epsilon-205Tl and Ga in late-stage muscovite appears to be a favorable indicator of rare-element enrichment LCT
pegmatites and may be a useful exploration vector.
Stratigraphy and lithogeochemistry of rocks from the Nugget Pond Deposit area, Baie Verte Peninsula, Newfoundland
Authors: Mueller C , Piercey S J , Babechuk M G , Copeland D
Published: October 2021

Stratigraphic and lithogeochemical data were collected from selected drill core from the Nugget Pond gold deposit in the Betts Cove area, Newfoundland. The stratigraphy consists of a lower unit of basaltic rocks that are massive to pillowed (Mount Misery
Formation). This is overlain by sedimentary rocks of the Scrape Point Formation that consist of lower unit of turbiditic siltstone and hematitic cherts/iron formations (the Nugget Pond member); the unit locally has a volcaniclastic rich-unit at its base and grades upwards into finer grained
volcaniclastic/turbiditic rocks. This is capped by basaltic rocks of the Scrape Point Formation that contain pillowed and massive mafic flows that are distinctively plagioclase porphyritic to glomeroporphyritic. The mafic rocks of the Mount Misery Formation have island arc tholeiitic affinities,
whereas Scrape Point Formation mafic rocks have normal mid-ocean ridge (N-MORB) to backarc basin basalt (BABB) affinities. One sample of the latter formation has a calc-alkalic affinity. All of these geochemical features are consistent with results and conclusions from previous workers in the area.
Clastic sedimentary rocks and Fe-rich sedimentary rocks of the Scrape Point Formation have features consistent with derivation from local, juvenile sources (i.e., intra-basinal mafic rocks). The Scrape Point Formation sedimentary rocks with the highest Fe/Al ratios, inferred to have greatest amount
of hydrothermally derived Fe, have positive Ce anomalies on Post-Archean Australian Shale (PAAS)-normalized trace element plots. These features are consistent with having formed via hydrothermal venting into an anoxic/ sub-oxic water column. Further work is needed to test whether these redox
features are a localized feature (i.e., restricted basin) or a widespread feature of the late Cambrian-early Ordovician Iapetus Ocean, as well as to delineate the role that these Fe-rich sedimentary rocks have played in the localization of gold mineralization within the Nugget Pond
deposit.
Stratigraphy and lithogeochemistry of the Goldenville horizon and associated rocks, Baie Verte Peninsula, Newfoundland
Authors: Mueller C , Piercey S J , Babechuk M G , Copeland D
Published: October 2021

The Goldenville horizon in the Baie Verte Peninsula is an important stratigraphic horizon that hosts primary (Cambrian to Ordovician) exhalative magnetite and pyrite and was a chemical trap for younger (Silurian to Devonian) orogenic gold mineralization. The
horizon is overlain by basaltic flows and volcaniclastic rocks, is intercalated with variably coloured argillites and cherts, and underlain by mafic volcaniclastic rocks; the entire stratigraphy is cut by younger fine-grained mafic dykes and coarser gabbro. Lithogeochemical signatures of the
Goldenville horizon allow it to be divided into high-Fe iron formation (HIF; >50% Fe2O3), low-Fe iron formation (LIF; 15-50% Fe2O3), and argillite with iron minerals (AIF; <15% Fe2O3). These variably Fe-rich rocks have Fe-Ti-Mn-Al systematics consistent with element
derivation from varying mineral contributions from hydrothermal venting and ambient detrital sedimentation. Post-Archean Australian Shale (PAAS)-normalized rare earth element (REE) signatures for the HIF samples have negative Ce anomalies and patterns similar to modern hydrothermal sediment
deposited under oxygenated ocean conditions. The PAAS-normalized REE signatures of LIF samples have positive Ce anomalies, similar to hydrothermal sediment deposited under anoxic to sub-oxic conditions. The paradoxical Ce behaviour is potentially explained by the Mn geochemistry of the LIF samples.
The LIF have elevated MnO contents (2.0-7.5 weight %), suggesting that Mn from hydrothermal fluids was oxidized in an oxygenated water column during hydrothermal venting, Mn-oxides then scavenged Ce from seawater, and these Mn-oxides were subsequently deposited in the hydrothermal sediment. The
Mn-rich LIF samples with positive Ce anomalies are intercalated with HIF with negative Ce anomalies, both regionally and on a metre scale within drill holes. Thus, the LIF positive Ce anomaly signature may record extended and particle-specific scavenging rather than sub-oxic/redox-stratified marine
conditions. Collectively, results suggest that the Cambro-Ordovician Taconic seaway along the Laurentian margin may have been completely or near-completely oxygenated at the time of Goldenville horizon deposition.
Stress, Anxiety, Depression, and Resilience in Cancer Patients on Chemotherapy
Authors: Chaudhury Suprakash , Jagtap Biswajit , Shailaja B. , Mungase Mrudula , Saini Rajiv Kumar , Jain Vandana
Published: October 2021

Background:

Cancer chemotherapy is an intense and cyclic treatment that is associated with a number of distressing side effects that may affect the person's psyche.

Aim:

The aim of the study is to evaluate stress, anxiety, depression, and resilience in cancer patients undergoing chemotherapy.

Materials and Methods:

Consecutive cancer patients undergoing chemotherapy at a tertiary care rural medical college hospital were included in the study with their consent. Patients having comorbid medical or psychiatric disorders were excluded. Demographic and clinical characteristics of the patients were recorded. The Depression Anxiety Stress Scale and Abbreviated Connor-Davidson Resilience Scale were administered and scored as per the test manual. The data were analyzed using the SPSS software with t-test, Chi-square test, Mann–Whitney U-test, Spearman's correlation, and multiple regression analysis.

Results:

The study included 32 male and 68 female cancer patients on chemotherapy. Depression was found in 33 patients, anxiety was observed in ten patients while stress was present in three patients. Stress was positively correlated to anxiety and depression, while resilience was negatively correlated to depression. There were no gender differences in stress, anxiety, depression, or resilience. A multiple regression was run to predict depression from stress, anxiety, and resilience. These variables statistically significantly predicted depression, F (3,96) =55.075, P < 0.0001, R
2 = 0.632. All three variables added statistically significantly to the prediction (P < 0.05).

Conclusion:

One-third of cancer patients on chemotherapy suffer from depression which is negatively correlated with resilience. Significant predictors of depression in these patients were stress, anxiety, and resilience. Psychiatric management in addition to reducing depression, stress, and anxiety should also aim to increase resilience in these patients.

Published: October 2021

Context:

Childhood adversity is highly prevalent and is associated with depression.

Aims:

The aim of the study is to assess the occurrence of adverse childhood experiences (ACEs) in male and female patients suffering from depression, measure its relationship with the severity of depression, and evaluate the association of factors across gender.

Settings and Design:

A cross-sectional study was conducted.

Subjects and Methods:

A total of 100 adult depressed patients were evaluated to calculate the severity of depression and the ACE score.

Statistical Analysis Used:

Statistical analysis was performed using Chi-square test and binary logistic regression.

Results:

One or more categories of ACEs were reported in 70% of male and 68% of female patients. The most common was violence between adults in the household and physical abuse. In male patients, there was a significant association between severity of depression and experiencing three or more categories of childhood adversity (P = 0.01).

Conclusions:

Childhood adversity occurs frequently and is associated with severity of depression in the male cohort.

Authors: Nagose Vaishali Baburao , Soni Dharmishta Naman , Rathod Shivanand Shriram , Yelne Yaminee Avinash
Published: October 2021

Context:

The COVID-19 pandemic has affected all the age groups, especially worsening the already stressful life of college students.

Aims:

The aims are to study the differences in the COVID-19 impact on mental health including depression, sleep quality, and various areas of life in undergraduate students (medical and nonmedical) and medical interns.

Subjects and Methods:

A cross-sectional study in the form of an online survey was conducted through Google Form containing the questionnaire having Kessler Psychological Distress Scale (K10), Pittsburgh Sleep Quality Index (PSQI), questions pertaining to the different aspects of life affected due to COVID-19.

Statistical Analysis Used:

The results of the groups were compared using two sample t-test and one-way ANOVA.

Results:

A total of 355 students responded (202 medical and 101 nonmedical students and 52 medical interns). The difference in psychological distress and sleep quality was statistically significant in all three groups. The average scores of K10 depicted psychological distress being moderate in nonmedical and mild in medical students and interns; of PSQI showed the prevalence of poor sleep quality being maximum in interns and minimum in medical students. 40% medical students reported positive impact on diet and about half of the medical and nonmedical students on familial relationships.

Conclusions:

Statistically significant differences in the three study groups with respect to psychological distress, sleep quality, and COVID-19 impact on various aspects of life indicate the requirement of identification of their different needs and required interventions including mental health support, possibly at the institutional levels are the need of the hour.
Electrocardiographic Findings in Coronavirus Disease-19 and its Correlation with Clinical Severity of Disease
Authors: Khan Mumtaz Ali , Menon Anindita , Nagaraja B. S.
Published: October 2021

Background and Aims:

Most data on electrocardiographic (ECG) changes in patients with coronavirus disease-19 (COVID-19) have been presented without comparison to patients with other acute respiratory illnesses. The correlation of ECG changes with disease severity has also not been studied.

Subjects and Methods:

We compared forty COVID-19-positive and forty COVID-19-negative patients in terms of clinical presentation, ECG at admission, and cardiac biomarkers. Statistical analysis was presented as frequency (percentage) and continuous as mean ± standard deviation. Chi-square test/Fischer's exact test was used.

Results:

Mean age overall in the study was 52.4 ± 16 years, 67.5% data were males. About 87.5% of the COVID-positive patients and 70% of the COVID-negative patients had ECG changes at baseline. Sinus tachycardia was seen in 45% (18/40) of COVID-positive patients. About 95% (38/40) of COVID-19 positive patients had normal axis, 5% (2/40) had supraventricular tachycardia, 2.5% (1/40) had premature atrial contractions (PACs), and 7.5% (3/40) had premature ventricular contractions. One patient had ventricular bigeminy. About 7.5% (3/40) of COVID-positive cases had complete right bundle branch block (RBBB), one had complete left bundle branch block (LBBB), whereas one had incomplete LBBB. About 7.5% (3/40) of COVID-positive cases had ST-segment elevation, one of whom also developed postmyocardial infarction left ventricular thrombus. About 15% (6/40) had nonST-segment elevation acute coronary syndrome.

Conclusions:

COVID-19 patients have ECG changes of left-sided heart disease (PACs and LBBB) and right-sided disease (RBBB, right axis deviation, and right ventricular strain pattern) at presentation, however, right heart changes predominate. COVID-19 patients had a higher occurrence and a wider variety of ECG changes at presentation than other acute respiratory illnesses and these changes correlate well with clinical disease severity as does troponin I level.
COVID-19 Vaccines

Published: October 2021

Infectious agents are still in circulation in different parts of the world, and globalization, with travel on the agenda, migration, and poverty, makes vaccination a tool more than ever necessary. Despite the impressive number of studies carried out since the virus was first characterized, there are still many unknowns about this disease. Moreover, it is precisely these unknowns that fully justify the very different conceptual and technological strategies that are currently pursued in the preparation of vaccines against COVID-19. Due to the short development time and the novelty of the technologies adopted, these vaccines will be deployed with several unresolved issues that only the passage of time will permit to clarify. Technical problems connected with the production of billions of doses and ethical ones connected will be needed to ensure equitable global access, protection of diverse subjects, and immunity against viral variants.

Discussion:

The nurses who were younger at age tend to be more stressed than the older nurses which could be due to the fact that younger nurses might have felt nervous due to their inexperience and poor preparation for their occupational role at work.

Conclusion:

Increasing the awareness and educating nurses toward the essential need for addressing their mental health issues with timely and adequate support measures is recommended.

This study aimed to investigate the effect of mealworm (Tenebrio molitor) derived protein supplementation on skeletal muscle atrophy of hindlimb casted immobilized rats. Twenty-four six-week-old male Sprague-Dawley rats were randomly divided into three groups: control sedentary group (CD, n = 8), control diet casting group (CDC, n = 8), and the mealworm-derived protein supplemented casting group (MDC, n = 8). CD and CDC group was supplemented AIN-76G diet and mealworm-derived protein supplemented diet for MDC group was substituted as 5% casein protein to 5% mealworm protein for 5 weeks and left hindlimb casting immobilization using casting tape for CDC and MDC group was done 1 week before sacrifice. After 5 weeks of mealworm supplementation, the soleus muscle weight of the MDC group was significantly higher compared to the CDC group. In addition, the level of muscle protein synthesis factors p-Akt/Akt, p-4EBP1/4EBP1, and p-S6K/S6K significantly increased in the MDC group compared to the CDC group. On contrary, the level of muscle protein degradation factors (MuRF1 and atrogin-1) was significantly lower in the MDC group than that of the CDC group. These results suggest that mealworm-derived protein supplementation may have a significant role in the prevention of skeletal muscle atrophy via stimulation of muscle protein synthesis factors and inhibition of muscle protein degradation factors, and therefore a promising intervention in sarcopenia.

Skin permeation is an integral part of penetration of topical therapeutics. Zero order in addition to Higuchi permeation kinetic is usually preferred in topical drug delivery cargo. Penetration of therapeutic entities through epidermal barrier is a major challenge for scientific fraternity. Furthermore, penetration of therapeutic entities determines the transportation and ultimately therapeutic efficacy of topical dermal dosage forms. Apart from experimentation models, mathematical equations, in silico docking, molecular dynamics (MDs), and artificial neural network (Neural) techniques are being used to assess free energies and prediction of electrostatic attractions in order to predict the permeation phenomena of therapeutic entities. Therefore, in the present review, we have summarized the significance of kinetic equations, in silico docking, MDs, and ANN in assessing and predicting the penetration behavior of topical therapeutics through dermal dosage form. In addition, the role of chitosan biomacromolecule in modulating permeation of topical therapeutics in skin has also been illustrated using computational techniques.
Photogram: The Art of Recording Shapes in Photography as Media for Enhaching Creativity in Children's Communication
Authors: Widiastuti Ni Made
Published: October 2021

Photogram is a technique that produces images without using a camera as an image recording aid. However, it makes more use of sunlight and chemicals as recording materials. The photos from this photogram are in the form of a silhouette or an outline of the object being recorded. Considering the dangers of chemicals for children, using natural dyes is friendlier to them. Therefore, the process of conveying messages through photographs by children can run well. This study aims to analyze the 4P elements (Personal, Process, Press, Product) of photogram's work as an enhancer of creativity in children's communication. This study uses a descriptive qualitative approach which will elaborate the data by describing them into sentences. The technique of collecting data is in the form of observing photogram works, documenting the work and looking for references through literature study. The photographic works produced by the children will be studied in terms of creativity by describing the 4P elements. Apart from that through the photographic works produced by these children, it can be concluded that creativity arises because of one's own interaction with the environment which is then processed and supported by the people around them and the environment so that it becomes creative photogram work. It is also intended that photogram can become an alternative media in honing children's creativity in communicating with their environment.

People’s Responsibility towards Organ Donation an Unanswered Appeal
Authors:   Faculty of Medical Sciences, Catholic University of Buenos Aires, Argentina, Félix Cantarovich
Published: October 2021

People easily agree with the principle of organ donation; nevertheless, when a person dies, their relatives often refuse to honour this agreement. Because of this persistent social conduct, organ shortage is responsible for the rising mortality of patients on organ waiting lists. This sad reality continues despite the ongoing education effort with the enduring slogan: “Organ donation is a gift of life”.
Responsiveness of Service Sector Growth to Financial Development in Nigeria: Evidence from 1981-2019
Authors: Amalu Henry Ikechukwu , Agbasi Lucy Obiageli , Olife Loenard U. , Okechukwu Anthony
Published: October 2021

Purpose: This paper explores the relationship between financial development and output of the service sector in Nigeria over the period 1981-2019. It presents an analysis of the long-run and short-run impacts of financial development on the performance growth of the service sector, as well as the cointegration between the variables.
Approach/Methodology/Design: We test the time series for stationarity using Phillips-Perron and Augmented Dickey-Fuller unit root tests. We adopt the Auto-Regressive Distributed Lag (ARDL) approach to analyze the relationship between financial development and service sector performance in Nigeria. Market capitalization, monetization ratio, and the ratio of credit to the private sector to GDP represent the indicators of financial development.
Findings: The results of the study show that market capitalization and monetization ratio have significant positive impacts on service sector output, respectively. However, the effect of credit to the private sector on service sector performance is insignificant and negative. We find no cointegration among the investigated variables; while, the result of the error correction estimation indicates that it takes about two years to restore the long-run equilibrium after a deviation. In light of the findings made, this paper concludes that financial development exerts a significant positive effect on service sector performance in Nigeria.
Practical Implications: This study is valuable at this period of economic uncertainties in Nigeria. With input from this paper, policymakers in the public sector via the formulation and implementation of effective policy measures such as fiscal measures can channel the benefits of financial sector development to the service sector to create an enabling business environment for the sector, especially as it concerns the provision of private credit to the sector.
Originality/value: Based on literature review, this paper for the first time investigated the link between financial development and the performance of the service sector in Nigeria as defined by the CBN Statistical Bulletin 2019 edition.

Exploración de la memoria y escenarios de reparación simbólica desde el caso colombiano
Authors: Pirateque Perdomo Pamela , Ulloa Sánchez Kelly Stefanía
Published: October 2021

La memoria histórica es la representación de lo vivido y la forma de recordarlo para la posteridad, lo que implica que su desconocimiento, carácter subjetivo y descripción de los hechos son capaces de reafirmar o cuestionar lo sucedido en un determinado momento y espacio.  El presente artículo busca profundizar sobre la influencia de la memoria en los escenarios de reparación simbólica, teniendo en cuenta la sociedad colombiana como un ejemplo de preservación de memoria doméstica en esferas internacionales, partiendo así del entendimiento del conflicto armado interno, su desarrollo, periodos y actores.  Esto, a la luz de perspectivas académicas en las que se incluyan los distintos tipos de memoria (individual, colectiva e histórica) y el proceso de reparación simbólica en el marco del conflicto. Finalmente, se logra concluir que la preservación de la memoria sigue siendo un proceso constante en la sociedad, ya que trata de reconocer los hechos, de construir la verdad sobre los mismos y garantizar su reparación (simbólica). Al mismo tiempo, que trata de evitar la repetición de hechos bélicos que generen nuevas víctimas, y la negación de la memoria, construcción de nuevas realidades que evadan la versión real de lo vivido.
