Antara Selfie Dan Selfless: Sebuah Tinjauan Teologis Terhadap Tren Instagram
Authors: Jatmiko Yudi
Published: April 2021

The emergence of Instagram has indisputably made the world full of pictures. Messages that are generally dominated by words have turned into a collection of colorful pictures on Instagram. Pictures have brought a world that is beyond words. On the other hand, many experts observe the destructive sides of Instagram. The pictures that are initially meant to reveal beauty have transformed into a means of self-fulfillment. Pictures have turned into a context where the self has become the center of the message and the world. In the Christian faith, this is fatal! A self-centered life is contradictory to the Christian nature as God’s image, which basically must center life on God. The question begs to answer: how should Christian respond to Instagram? This is the focus of the research. To answer the question above, using the methodology of phenomenology approach and literary research, I will explain the history and impacts of Instagram. After that, I will analyze it from the perspective of the Christian faith, especially those that are related to the philosophy undergirding Instagram. Finally, I believe Instagram is not evil per se. However, appropriate responses are needed to bring forth a clearer God’s image in the world that is full of pictures.
Membangun Solidaritas Kemanusiaan: Kritik Nabi Amos Terhadap Praktik Pelanggaran Hak Asasi Manusia
Authors: Pakpahan Gernaida K.R.
Published: April 2021

This research aims to explore the implementation of human rights in the 8th century BC. The prophet Amos's criticism was aimed at the failure of nations to build human solidarity which was shown in various human rights violations. The approach method used is a form criticism approach, a synchronic and diachronic approach that seeks to examine the historical context of the book of Amos. The results obtained from the research show that violations of human rights during the Amos era include: deprivation of one's right to life and property, trafficking and human slavery, loss of fraternal solidarity, anger, and revenge, intimidation, terror and fear, the humiliation of human beings, refusal. rule of law. Israel's crimes against humanity are driven by a materialistic spirit so that it carries out the sale of the righteous, the poor, the weak, the exploitation of women, fines, and debts. Building humanitarianism through law enforcement so that truth and justice are created in society.

ANALYSIS OF STUDENTS PERFORMANCE IN RELATION TO THE RESULTS OF STATE UNIFIED EXAM: THE CASE OF RUSSIAN UNIVERSITY
Authors: Svirina Anna , Lopatin Aleksey , Titko Jelena
Published: April 2021

Purpose – Considering the limited number of studies covering the topic, the goal is to check the existence of the correlation between the results of Russia’s Unified State Exam and performance at the university.
Research methodology – the article uses quantitate analysis (regression) of the student performance on a sample of 4664 students. To provide statistical evaluation, the authors use SPSS Statistics software.
Findings – the research suggests, that results of unified state exam and individual students scores, awarded by the university under restrictions, are non-efficient in terms of predicting student performance. On the opposite, students’ performance during their first semester is a good predictor for the whole period of academic studies. As existing results of testing such hypotheses are inconsistent, the research provides value to the field of educational research.
Research limitations – data for research refer to only Kazan National Research Technical University named after A. N. Tupolev (KNRTU-KAI).
Practical implications – the research clearly indicate, that the universities cannot rely solely on the unified state exam during admission; they are to use different assessment tools to ensure future academic performance and lower dropouts rate.
Originality/Value – There is a gap in the investigation the link between secondary education and higher education performance.

Also accepted synonymy of S. campadellii Nobile & Turrisi, 2004 = S. geoffrellus (Kirby, 1802), previously suggested by M. Schwarz’s and F. Gusenleitner’s (2012).
The remarkable biology of a new species of Gelis Thunberg, 1827 (Ichneumonidae, Phygadeuontinae), a solitary endoparasitoid of fresh eggs of Timarcha (Coleoptera, Chrysomelidae)
Authors: Shaw Mark R. , Kan Pieter , Kan-van Limburg Stirum Brigitte , Schwarz Martin
Published: April 2021

A new species, Gelis timarchae Schwarz, Shaw & Kan, is figured and described from specimens reared as a solitary endoparasitoid of fresh eggs of Timarcha nicaeensis in the south of France. Oviposition behaviour of the adult parasitoid, directly into the host cytoplasm, is described and links to videos are given. This appears to be the first record of any ichneumonid developing as an endoparasitoid of an insect egg, and it is a major departure from hitherto known ectoparasitoid (or spiders’ egg-predation) behaviour in the genus Gelis. Fluid from the host egg issuing from the base of the parasitoid’s ovipositor early in the oviposition process is interpreted as a necessary reduction of hydrostatic pressure before the parasitoid egg can be forced down the ovipositor. The egg and first instar larva are figured; the latter is caudate, with the caudal appendage very unusual in being bifurcate. The complex phenology and diapause of the parasitoid were investigated partly experimentally; it is broadly bivoltine with a prepupal diapause in summer, but extra generations and prolonged diapause were both also seen.

Authors: Wendling Jean-Michel , Sabatier Jean-Marc , Kopferschmitt Jacques
Published: April 2021

Introduction : une équipe pakistanaise a réalisé un essai clinique multicentrique et randomisé en 2020, avec un traitement appelé HNS comportant du miel et la plante nigelle (Nigella sativa) sur des individus COVID-19. Matériel et méthodes : l’essai a été mené dans quatre établissements de soins médicaux au Pakistan. Le protocole multicentrique randomisé concerne 316 patients COVID-19 (210 présentant des signes cliniques modérés et 103 des signes sévères). Parmi les cas modérés, 107 ont bénéficié du traitement incluant Nigella sativa (80 mg/kg/jour) et Miel (1g/kg/jour) par voie orale jusqu’à 14 jours, tandis que 103 ont pris un placebo. Pour les cas graves, 50 patients ont reçu le HNS et 53 ont reçu le placebo. Résultats : il a été observé une réduction de la durée des symptômes à 6 jours (traités) contre 13 jours (placebo) pour les cas COVID-19 sévères, et de 4 jours (traités) contre 7 jours (placebo) pour les cas COVID-19 modérés. Le HNS a réduit le portage viral d’environ 4 jours pour les cas sévères ou modérés. Le traitement HNS a amélioré le score clinique au jour 6 avec une reprise d’activité normale dans 64 % contre 11 % parmi les cas modérés, et une sortie de l’hôpital dans 50 % des cas contre 3 % dans les cas graves. Pour les cas graves, le taux de mortalité a été réduit de 82 %. Aucun effet indésirable lié au HNS n’a été observé. Conclusion : le mélange HNS comportant du miel et de la nigelle semble très actif pour traiter des individus présentant une COVID-19 sévère ou modérée. Après confirmation de cette activité, le mélange HNS pourrait être potentiellement utilisé pour un traitement de tels malades.
La thérapie cellulaire et vésiculaire en endoscopie digestive interventionnelle
Authors: Berger Arthur , Rahmi Gabriel
Published: April 2021

Introduction : Les fistules post-opératoires sont des complications fréquentes, responsables d’une morbi-mortalité élevée. La prise en charge de ces fistules est complexe. Les vésicules extracellulaires (VE) ou « poussière cellulaire » représentent un outil innovant et prometteur de la médecine régénérative. L’objectif de cette présentation est de montrer le potentiel thérapeutique des VEs dans le traitement endoscopique des fistules post-opératoires. Méthodes : Nous avons évalué l’effet des VEs sur la fermeture des fistules digestives, sur trois modèles animaux de fistules digestives chez le rat et le porc. Nous avons créé un modèle de fistules œso-cutanées chez le porc, et un modèle de fistules colo-cutanées et gastro-cutanées sur sleeve gastrectomie chez le rat. Résultats : La fermeture des fistules était significativement plus importante dans le groupe gel + VE, que dans le groupe gel seul et dans le groupe témoin. Ces résultats ont été confirmés dans les 3 modèles animaux. La vitesse de cicatrisation est plus rapide après traitement par VEs. L’inflammation et la fibrose histologique étaient significativement moins importantes dans le groupe Gel + VE. L’évaluation par IRM et TEP scan montre une tendance à la réduction de l’inflammation et de la taille du trajet de fistules. Conclusion : Ces études sur le petit et gros animal confirment que les vésicules extracellulaires présentent des propriétés régénératives. En effet, l’application de VEs induisait une fermeture significative des fistules associée à une diminution de l’inflammation et de la fibrose. Ces résultats prometteurs nous incitent à évaluer ce traitement dans le cadre d’une étude clinique de phase I/II.

Dans ce travail, nous proposons de souligner certaines articulations entre la parole et l’écriture, en montrant ce qui les distinguent et, plus particulièrement, les croisements qui s’opèrent entre elles. Nous pourrions penser ces articulations à partir de registres complémentaires, qui font spécifiquement référence au sens : ce qui ne parvient pas à être dit a besoin d’être écrit, afin de compléter la parole. Une autre perspective, moins évidente, est de dire qu’il existe peut-être quelque chose du registre d’une écriture dans la parole et de la parole dans l’écriture, et que leurs effets ne s’observent que lorsqu’on passe d’un registre à l’autre.

Vies pøtentielles de Camille de Toledo (né en 1976) est un livre passionnant. Notamment par la façon dont il noue 47 évocations mythologiques de fêlés et d’aliénés caractéristiques de ce début de xxi e  siècle avec son histoire personnelle au fil d’« exégèses » qui questionnent autant l’auteur que son temps. Il y a là une façon très neuve de faire éclater le cadre autobiographique et de redonner à la narration d’« histoires » des résonances inattendues.

En passant par l’art, la littérature et la clinique, je m’interroge sur les limites de l’écriture de soi et de l’analyse, sur ce qui résiste au discours. Il y a un reste, un irracontable, qui divise le sujet entre ce qu’il est devenu et ce qu’il ne peut plus être. Une part de soi ne cesse de disparaître du miroir, ou dans le regard de l’autre, ce dont les mots, les mots des autres parfois, gardent sinon le souvenir, la possibilité d’un souvenir. Comment transformer certaines identifications traumatiques en récits de soi ? Comment l’analyse peut-elle offrir la protection nécessaire à leur élaboration ?

Peut-on écrire son autoportrait ? Cette question se pose à partir d’un autoportrait littéraire rédigé par Blandine Solange, femme peintre psychotique aux prises avec un puissant délire érotique. Dans une période d’instabilité profonde, elle voulut décrire ce qu’elle appelle : ses « performances ». Celles-ci sont les mises-en-scène de son délire : débauches érotiques verbales plus encore que picturales. Nous nous surprenons de la rupture entre la crudité des descriptions et la quasi-timidité des toiles. Qu’est-ce qui ne circule pas de la toile à l’écriture ? Ceci interroge l’Idéal du moi et le statut de l’objet. Rédiger ce livre ne suffira pas à écarter le suicide. L’interrompant, elle se pendra. L’étude des portraits permet de faire quelques hypothèses sur ce qui échoua à l’écriture. Doit-on supposer que la dimension imaginaire inhérente à la peinture contenait son délire ? N’est-il pas permis de supposer que le suicide procède d’une ultime performance ? Pour clore, précisons qu’elle débuta et interrompit une analyse, qui nous invite à questionner la direction de la cure.

Sherlock Holmes est un véritable mythe séculier . Sa célébrité à travers le monde est exceptionnelle. Le détective se joue de la limite entre réalité et fiction pour s’installer profondément et durablement dans la surréalité psychique individuelle et collective. Paradoxalement, le médecin écossais Arthur Conan Doyle portait très peu d’estime littéraire à son célèbre héros et préférait de beaucoup ses autres romans : « Mes plus basses œuvres rejettent dans l’ombre ce dont je suis le plus fier. » En 1893, il assassine sa créature dans le numéro 36 du Strand Magazine où il publie Le dernier problème . A.C. Doyle reçoit d’innombrables courriers de lecteurs scandalisés l’insultant et lui demandant la renaissance du héros. Dans les semaines qui suivent le Strand Magazine perd plus de 20 000 abonnés. À l’occasion de cette communication, j’explorerai quelques-uns des fils de la tresse de cette écriture de soi et des limites chez Doyle à travers la fiction détective. L’inséparable chroniqueur-narrateur John Watson, l’observation, la logique indicielle de la méthode iconoclaste du consulting détective y seront envisagés comme les caractéristiques d’un cadre propice aux dénouements de crises dont les récits ne peuvent laisser insensible le clinicien et invitent au débat avec les écrivains et les spécialistes de la littérature.

Écritures de soi, Écritures des limites
Authors: Somé Isabelle
Published: April 2021

Au fil des lectures analytiques, l’écriture autofictionnelle m’est apparue comme une écriture limite extrêmement enrichissante sur le plan clinique. Elle met notamment en lumière le drame des fonctionnements limites, déchirés entre deux noyaux incompatibles de leur self, un enfant traumatisé psychotique et un petit Œdipe dont les désirs n’ont pas été refoulés. Ce clivage les condamne à un état de mort-vivant dont l’écriture autofictionnelle leur permet de sortir grâce à une identification de leur témoin interne au père de la psychanalyse. Ernst Weiss, écrivain autrichien contemporain de Freud, a inventé ce genre autofictionnel et lui est resté fidèle jusqu’à son dernier roman Le témoin oculaire , écrit en exil en 1938. Ce texte montre bien comment l’identification à Freud permet à un écrivain broyé d’échapper au chaos, au moins le temps de l’écriture, et de relever la tête.

Sylvia Plath (1932-1963), devenue après son suicide une figure majeure de la poésie américaine, se définit comme A Fragmentary girl dans son Journal. Vivre-écrire est d’un seul tenant dans une œuvre où la dimension autobiographique est explicite, et revendiquée : l’écriture puise aux sources de l’expérience vécue, de la plus quotidienne aux plus extrêmes (le suicide manqué à 20 ans, la mort du père à 9 ans et sa perte interminable ), mais elle est aussi la condition de la vie , recréée par les mots et leur galop infatigable . Comment les différentes formes que prend cette écriture de soi ( Journaux , nouvelles, roman, poèmes), remanient-elles le fait biographique, chacune à leur manière, entre retrouvailles avec l’objet perdu et résistance de soi à la mort, défense contre le deuil et conservation mélancolique ? Comment et jusqu’où le travail d’écriture permet-il à S. Plath d’être vraie à l’égard de ses propres étrangetés , comme elle veut l’être ? À quelles limites aussi se heurtent et la passion et le métier d’écrire ?
Part du profit dans le revenu : 1/3, une valeur de référence ?
Authors: Villemeur Alain
Published: April 2021

La répartition du revenu entre le capital et le travail est considérée comme un problème majeur depuis Ricardo [1817]. Une valeur de 1/3 pour la part du profit dans le revenu est souvent rencontrée et constitue un fait stylisé pour de nombreux modèles de croissance. Cet article propose une explication théorique basée sur un modèle de croissance endogène et keynésien ; le point de départ est une idée de Kaldor [1972], la croissance économique étant le résultat d’une réaction en chaîne entre les accroissements de l’offre et de la demande liés aux investissements décidés par les entrepreneurs et qui dépendent de la demande effective et de l’efficacité marginale du capital. Il est démontré que le « nombre magique » de 1/3 est théoriquement justifié quand la croissance du salaire est indépendante de la croissance de l’emploi. Une part du profit supérieure à 1/3 conduit à un ralentissement économique. Les enseignements théoriques sont cohérents avec la réalité de l’économie américaine de 1961 à 2018 et avec les faits stylisés établis par des économistes (Verdoorn, Okun, Ferri, Bhaduri-Marglin, Piketty).
Phase transitions of the SIR Rumor spreading model with a variable trust rate
Authors: Choi Sun-Ho , Seo Hyowon , Yoo Minha
Published: April 2021

We study a threshold phenomenon of rumor outbreak on the SIR rumor spreading model with a variable trust rate depending on the populations of ignorants and spreaders. Rumor outbreak in the SIR rumor spreading model is defined as a persistence of the final rumor size in the large population limit or thermodynamics limit \begin{document}$ (n\to \infty) $\end{document}, where \begin{document}$ 1/n $\end{document} is the initial population of spreaders. We present a rigorous proof for the existence of threshold on the final size of the rumor with respect to the basic reproduction number \begin{document}$ \mathcal{R}_0 $\end{document}. Moreover, we prove that a phase transition phenomenon occurs for the final size of the rumor (as an order parameter) with respect to the basic reproduction number and provide a criterion to determine whether the phase transition is of first or second order. Precisely, we prove that there is a critical number \begin{document}$ \mathcal{R}_1 $\end{document} such that if \begin{document}$ \mathcal{R}_1>1 $\end{document}, then the phase transition is of the first order, i.e., the limit of the final size is not a continuous function with respect to \begin{document}$ \mathcal{R}_0 $\end{document}. The discontinuity is a jump-type discontinuity and it occurs only at \begin{document}$ \mathcal{R}_0 = 1 $\end{document}. If \begin{document}$ \mathcal{R}_1<1 $\end{document}, then the phase transition is second order, i.e., the limit of the final size is continuous with respect to \begin{document}$ \mathcal{R}_0 $\end{document} and its derivative exists, except at \begin{document}$ \mathcal{R}_0 = 1 $\end{document}, and the derivative is not continuous at \begin{document}$ \mathcal{R}_0 = 1 $\end{document}. We also present numerical simulations to demonstrate our analytical results for the threshold phenomena and phase transition order criterion.
Existence of unstable stationary solutions for nonlinear stochastic differential equations with additive white noise
Authors: Lv Xiang
Published: April 2021

This paper is concerned with the existence of unstable stationary solutions for nonlinear stochastic differential equations (SDEs) with additive white noise. Assume that the nonlinear term \begin{document}$ f $\end{document} is monotone (or anti-monotone) and the global Lipschitz constant of \begin{document}$ f $\end{document} is smaller than the positive real part of the principal eigenvalue of the competitive matrix \begin{document}$ A $\end{document}, the random dynamical system (RDS) generated by SDEs has an unstable \begin{document}$ \mathscr{F}_+ $\end{document}-measurable random equilibrium, which produces a stationary solution for nonlinear SDEs. Here, \begin{document}$ \mathscr{F}_+ = \sigma\{\omega\mapsto W_t(\omega):t\geq0\} $\end{document} is the future \begin{document}$ \sigma $\end{document}-algebra. In addition, we get that the \begin{document}$ \alpha $\end{document}-limit set of all pull-back trajectories starting at the initial value \begin{document}$ x(0) = x\in\mathbb{R}^n $\end{document} is a single point for all \begin{document}$ \omega\in\Omega $\end{document}, i.e., the unstable \begin{document}$ \mathscr{F}_+ $\end{document}-measurable random equilibrium. Applications to stochastic neural network models are given.

Published: April 2021

We present a non-iterative algorithm to reconstruct the isotropic acoustic wave speed from the measurement of the Neumann-to-Dirichlet map. The algorithm is designed based on the boundary control method and involves only computations that are stable. We prove the convergence of the algorithm and present its numerical implementation. The effectiveness of the algorithm is validated on both constant speed and variable speed, with full and partial boundary measurement as well as different levels of noise.

Acute Care Resource Use After Elective Surgery in the United States: Implications During the COVID-19 Pandemic
Authors: Krishnamoorthy Vijay , Ohnuma Tetsu , Bartz Raquel , Fuller Matthew , Khandelwal Nita , Haines Krista , Scales Charles , Raghunathan Karthik
Published: April 2021

Background

The COVID-19 pandemic created pressure to delay inpatient elective surgery to increase US health care capacity. This study examined the extent to which common inpatient elective operations consume acute care resources.

Methods

This cross-sectional study used the Premier Healthcare Database to examine the distribution of inpatient elective operations in the United States from the fourth quarter of 2015 through the second quarter of 2018. Primary outcomes were measures of acute care use after 4 common elective operations: joint replacement, spinal fusion, bariatric surgery, and coronary artery bypass grafting. A framework for matching changing demand with changes in supply was created by overlaying acute care data with publicly available outbreak capacity data.

Results

Elective coronary artery bypass grafting (n = 117 423) had the highest acute care use: 92.8% of patients used intensive care unit beds, 89.1% required postoperative mechanical ventilation, 41.0% required red blood cell transfusions, and 13.3% were readmitted within 90 days of surgery. Acute care use was also substantial after spinal fusion (n = 203 789): 8.3% of patients used intensive care unit beds, 2.2% required postoperative mechanical ventilation, 9.2% required red blood cell transfusions, and 9.3% were readmitted within 90 days of surgery. An example of a framework for matching hospital demand with elective surgery supply is provided.

Conclusions

Acute care needs after elective surgery in the United States are consistent and predictable. When these data are overlaid with national hospital capacity models, rational decisions regarding matching supply to demand can be achieved to meet changing needs.
Comparison of Sealing Ability of Bioceramic Sealer, AH Plus, and GuttaFlow in Conservatively Prepared Curved Root Canals Obturated with Single-Cone Technique: An In vitro Study
Authors: Kaul Shalan , Kumar Ajay , Badiyani Bhumika Kamal , Sukhtankar Laxmi , Madhumitha M. , Kumar Amit
Published: April 2021

Background:

Inadequate obturation techniques of the root canal system have been found to be the most frequent reason of failure post root canal treatment. An ideal endodontic sealer should fulfill all ideal requisites. The present study aimed to compare apical sealing ability between bioceramic (BC) sealer, GuttaFlow, and AH Plus.

Methodology:

One hundred and twenty-five curved roots of maxillary and mandibular third molar teeth with fully formed apex were collected for this study. The root canals were cleaned and shaped using a standard single-cone preparation to file at the established working length and divided into five groups of 25 each. Dye leakage was carried out. Group A: with GP, using EndoSequence BC sealer with conventional with 4% gutta-percha (Brasseler USA, Savannah, Georgia, USA); Group B: with ceramic coated with 4% gutta-percha (Brasseler USA, Savannah, Georgia, USA); Group C: with GP, using AH Plus sealer (Dentsply, De-Trey Konstanz, Germany) with 4% gutta-percha; Group D: with GuttaFlow bioseal (Roeko-Coltène/Whaledent, Langenau, Germany) with 4% Gutta-percha; and Group E is a negative control group. Statistical analysis was done using the Statistical Package for the Social Sciences software and Student's unpaired t-test.

Results:

The group AH Plus showed more leakage values than the GuttaFlow group and of two groups of BC sealer and negative control. Student's unpaired t-test disclosed no significant difference (P < 0.05) between the groups.

Conclusion:

None of the sealers used in the study could completely seal the apical foramen to have a fluid-tight seal.
Cerebral venous sinus thrombosis with meningitis in a child with disseminated staphylococcal disease
Authors: Gupta Shalu , Chopra Sanya
Published: April 2021

The availability of anti-staphylococcal antibiotics today has revolutionized the treatment strategies to fight Staphylococcus aureus. However, its virulent nature still remains a major cause of morbidity and mortality, especially in the pediatric age group. It presents with a wide spectrum of illnesses ranging from minor skin and soft-tissue infections to fatal necrotizing pneumonia and disseminated disease. However, its presentation as meningitis with septic venous sinus thrombosis in pediatrics remains a rare complication till date. We present the case of an 8-month-old girl child with disseminated staphylococcal disease (DSD) caused by community-acquired methicillin-sensitive S. aureus and complicated by acute mastoiditis, meningitis, and cerebral venous sinus thrombosis. This rare and severe manifestation of DSD was managed successfully with intravenous antibiotics and systemic anticoagulation.
Effect of slow tempo music on markers of anxiety during cataract surgery
Authors: Musa Azlan , Ng Qi Xiong , Wai Yong Zheng , Iqbal Tajunisah
Published: April 2021

PURPOSE:

This study aims to objectively measure the effect of slow tempo music on various markers for anxiety.

MATERIALS AND METHODS:

This is a repeated measure randomized control trial of patients with age-related cataracts undergoing cataract extraction through phacoemulsification under local anesthesia. Patients were randomized into two groups: music group where a standardized piano music was played and control group. Salivary alpha-amylase (sAA) levels were measured at the beginning and at the end of surgery. Blood pressure and heart rate were also measured at 5 min before surgery and at four other standardized points during and after surgery. Visual Analog Scale for anxiety was also gauged: preoperatively, perioperatively, and 15 min postoperatively.

RESULTS:

Ninety-two patients were randomized equally to the music group and control group. Paired sample t-test showed a reduction in the level of sAA during surgery in the music group (P = 0.019). The odds ratio for a drop in sAA with music was 4.407 (P = 0.001). Lower systolic blood pressure was observed in the music group: at delivery of local anesthesia (P = 0.047), at first incision (P = 0.023), and during sculpting (P = 0.15). Similarly, diastolic blood pressure was lower at first incision (P = 0.019) in the music group. The visual analog scale for anxiety during surgery was found to be lower in the music group (P = 0.046).

CONCLUSION:

A slow tempo music during cataract surgery was shown to significantly reduce several indicators for anxiety at various points during cataract surgery.

Authors: Ang Robert Edward T. , Rapista Aprille June B. , Remo Jocelyn Therese M. , Tan-Daclan Melody Ana T. , Cruz Emerson M.
Published: April 2021

PURPOSE:

The purpose of this study was to report the clinical and refractive outcomes of eyes with long axial length (AL) and high myopia that underwent cataract surgery and compare the performance of intraocular lens (IOL) calculation formulae on these eyes.

MATERIALS AND METHODS:

This retrospective cohort included 183 eyes that underwent cataract surgery from January 2010 to December 2018. Demographics, AL, postoperative best-visual acuities, IOL power data, and postoperative complications were recorded. Refractive outcomes were analyzed and absolute predicted errors were compared between five IOL calculation formulas.

RESULTS:

The mean age included in the study was 65.4 ± 9.39 years with a mean AL of 26.76 ± 1.75 mm. Postoperatively, the mean sphere, cylinder, and manifest refraction spherical equivalent were 0.22 D ± 0.54, −0.78 D ± 0.50, and − 0.16 D ± 0.50, respectively. The average IOL power implanted was 11.12 D ± 4.59 D. No intraoperative complications were encountered, but there was one incidence of retinal tear with detachment reported postoperatively (0.55%). The Kane formula had the lowest mean absolute predicted error (MAE). A significant positive correlation between increasing AL and MAE was seen in the Sanders, Retzlaff and Kraft-Theoretical (SRK-T) and Ladas formulae but not statistically significant when the Kane, Barrett Universal II, and the Emmetropia Verifying Optical (EVO) formulae were used.

CONCLUSION:

Cataract surgery in eyes with long ALs and high myopia is safe with a low incidence of intraoperative and postoperative complications. The Kane, Barrett, and EVO formulae were equally accurate in calculating the IOL power and achieved the least amount of residual error postoperatively.

Published: April 2021

Background:

Little is known about the nature of service users who seek crisis community care in recent times in the Australian context.

Objectives:

The objective of this study was to describe the sociodemographic, clinical, and service provision characteristics and 12-month clinical outcomes of patients in a metropolitan crisis intervention team.

Methods:

Patients who were registered during the study period (May 1, 2015–October 30, 2015) for crisis intervention from a metropolitan community mental health team were included for this retrospective cohort study. The type of psychosocial stressor triggering the crisis was assessed by the social readjustment scale.

Results:

A situational crisis or adjustment disorder (26.6%) was the most common primary diagnosis, followed by an affective disorder. Deliberate self-harm behavior was the leading risk behavior (18.1%). Major injury or illness to self (16%) was the main psychosocial stressor associated with crisis presentation. The primary health sector was the main source of referral and discharge destination. Nearly 40% of patients were re-referred within a 12-month period since index contact. The characteristics of re-referred patients were men, living with a housemate or other family, triage category C, diagnosis of a mood disorder, needing medication supervision, and discharged to inpatient treatment during the index episode of care.

Conclusions:

A continuous and collaborative model of care between the primary health sector and community mental health services might be more beneficial in the early identification and management of the acute crisis in a subgroup of patients. A diverse range of skills are needed for clinicians working in the crisis intervention service in the current times.

Authors: Ayad Zaid , Al Tabbah Samaa , Hazimeh Bassima , Sinno Loubna
Published: April 2021

Background:

Health-care workers during the COVID-19 outbreak are vulnerable to psychological distress due to increased workload, inadequate equipment, isolation, and risk of infection transmission. The objective of this study was to assess the psychological status of health-care professionals in Lebanon and Iraq during the period of COVID-19 outbreak. The primary outcome was the prevalence of depression, anxiety, and stress among the health-care workers.

Methods:

We carried out a cross-sectional study to assess the psychological well-being of health-care professionals in Lebanon and Iraq during the COVID-19 pandemic. Psychological health was assessed using the validated “Depression, Anxiety, and Stress Scale-21.” Results: A total of 518 health-care professionals were included, of which 287 (55.4%) were from Lebanon and 231 (44.6%) were from Iraq. Overall, 60.0%, 42.9%, and 43.4% of all participants reported depression, anxiety, and stress, respectively. Health-care workers from Iraq had more severe symptoms on all measurements compared to those from Lebanon. Psychological distress was associated with caring for elderly parents, going home after duty only 2–4 times/week, working overtime, and in the front line. The results present concerns about the psychological health of nurses and physicians. Those who did not use protective equipment were more distressed. Participants who had direct or indirect contact with COVID-19 cases and those who tested positive had significantly higher depression, anxiety, and stress.

Conclusions:

This survey on health-care workers reported high rates of depression, anxiety, and stress during the COVID-19 pandemic. Protecting health-care professionals is a major public health measure for addressing COVID-19 outbreak.

Published: April 2021

The study investigated the level of awareness and constraints the farmers were facing in adopting effective biosecurity measures in Ekiti State. Primary data were collected using multi-stage sampling technique to randomly select 150 fish growers, out of which 144 questionnaires were recovered. Analysis was carried out using descriptive statistics, four-point Likert scale and multiple regression. The result showed that 76.4% of the fish farmers with mean age of 40.48±10.28years were married, 61.1% owned the land on which they farm their fish, 73.6% operated as small scale fish farmers with farm size of <1 hectare. About 91.0% knew about fish diseases, the main source of pollution on the farm was flooding while some (61.1%) experienced outbreak of fish diseases at juvenile stage. High cost of facilities, lack of financial assistance, poor knowledge on biosecurity, expensive laboratory charges and inadequate monitoring by extension agents was perceived as the major constraints. The farmers need financial help to get adequate facilities and to enlarge their scale of operation. Adequate extension services to enlighten them on the effective biosecurity measures should be adopted.
Burden of diseases in fifty-three urban agglomerations of India due to particulate matter (PM2.5) exposure
Authors: Shende Pritanjali , Qureshi Asif
Published: April 2021

A nested 3d-chemical transport model, GEOS-Chem, was used to estimate the burden of disease (BoD) from PM2.5 exposure in fifty-three urban agglomerations (UAs) in India with population of 1 million or more, and the contribution of different chemical components to the PM2.5 burden in these locations. Premature mortality due to four diseases (ischemic heart disease, IHD, chronic obstructive pulmonary disease, COPD, stroke and lung cancer) caused by exposure to PM2.5 was estimated using an integrated exposure response function. The studied 53 UAs accounted for approximately 20% of the total premature mortality of 0.54 (0.45–0.63) million in India. Delhi had the maximum premature mortality (11945) followed by Kolkata (9204), Mumbai (8817), Bangalore (4528) Hyderabad (4157) and Chennai (3818). Premature mortality was 2% to 59% higher than the country average in model regions containing UAs. Contribution from different chemical components was in the order: organic carbon (18–30%) > NO3- (8–21%) > SO42- (5–16%) > NH4+ (6–9%) > black carbon (2.5–4%). Our estimates suggest policies targeting multiple compounds are required to achieve large reductions in PM2.5 pollution in urban regions.

Published: April 2021

In this study, pretreated organic wastes such as waste paper cups, cardboard waste, and vegetable waste were screened for the growth and lipid production of oleaginous bacteria DS-7 (isolated from the dairy effluent scum). The pretreated vegetable waste was found to be the best feedstock for biomass and lipid production by the DS-7. Further, process parameters such as inoculation time, substrate concentration (w/v) (amount of pretreated vegetable waste), pH, and inoculum size were optimized using a multi-objective optimization technique to enhance the biomass and lipid productions. The optimization study successfully enhanced the biomass concentration (g/L) and lipid content (%) by 47.9% and 15.84%, respectively in comparison with the unoptimized state. The biomass and lipid productivities were 42% (1.449 g/L/d) and 51% (1.267 g/L/d) greater than unoptimized conditions. The characteristics of the biodiesel obtained from the valorization of vegetable waste were comparable to the standard. Thus, the vegetable waste can be utilized as a potential feedstock for microbial biodiesel production.
Closed Analytic Formulas for the Approximation of the Legendre Complete Elliptic Integrals of the First and Second Kinds
Authors: Selescu Richard
Published: April 2021

The author proposes two sets of closedanalytic functions for the approximate calculus of thecomplete elliptic integrals of the first and secondkinds in the normal form due to Legendre, therespective expressions having a remarkablesimplicity and accuracy. The special usefulness of theproposed formulas consists in that they allowperforming the analytic study of variation of thefunctions in which they appear, by using thederivatives. Comparative tables including theapproximate values obtained by applying the two setsof formulas and the exact values, reproduced fromspecial functions tables are given (all versus therespective elliptic integrals modulus, k = sin ). It is tobe noticed that both sets of approximate formulas aregiven neither by spline nor by regression functions,but by asymptotic expansions, the identity with theexact functions being accomplished for the left end k= 0 ( = 0) of the domain. As one can see, the secondset of functions, although something more intricate,gives more accurate values than the first one andextends itself more closely to the right end k = 1 ( =90) of the domain. For reasons of accuracy, it isrecommended to use the first set until  = 70.5 only,and if it is necessary a better accuracy or a greaterupper limit of the validity domain, to use the secondset, but on no account beyond  = 88.2.

Meanwhile, male students are more prepared than female students. The implications of this study are also a big part of the discussion in this article.
WORLD FOOD CRISIS: CAUSES, TRENDS AND STRATEGY
Authors:   Dr. Baba Sahib Ammedkar Marathwada University Aurungabad (Maharashtra) India, Ghauri Farha Naz
Published: April 2021

The world is in the midst of a food crisis. The UN Chief Mr. Ban has rightly opined that the steeply rising price of food has developed into a real global crisis. Local manifestations in the shape of food riots and political protests should not obscure the global cause of the problem. Soaring food prices have created inflationary risks not seen in years. Food prices have risen 83 per cent in the last three years, bio-fuels accounting for a 30 per cent price hike. One hundred million live are endangered and 30 million have been dragged down into poverty by bio-fuel prices. Agricultural economists say that unless and until aggressive farm reforms are initiated in developing nations, especially emerging countries, the crisis could get much worse. But the future looks food with better prospects. India may lift restrictions on wheat and rice exports. Good output of rice is expected from India, Thailand and Vietnam. Bumper wheat output from India, Australia, the US and Canada. The United Nations must take immediate action in a concerted manner. Hence, there has been an urgent need to evolve a sound and effective strategy to overcome the crisis.
