Published: March 2021

Background
The COVID-19 outbreak has spread rapidly and hospitals are overwhelmed with COVID-19 patients. While analysis of nasal and throat swabs from patients is the main way to detect COVID-19, analyzing chest images could offer an alternative method to hospitals, where health care personnel and testing kits are scarce. Deep learning (DL), in particular, has shown impressive levels of performance when analyzing medical images, including those related to COVID-19 pneumonia.

Objective
The goal of this study was to perform a systematic review with a meta-analysis of relevant studies to quantify the performance of DL algorithms in the automatic stratification of COVID-19 patients using chest images.

Methods
A search strategy for use in PubMed, Scopus, Google Scholar, and Web of Science was developed, where we searched for articles published between January 1 and April 25, 2020. We used the key terms “COVID-19,” or “coronavirus,” or “SARS-CoV-2,” or “novel corona,” or “2019-ncov,” and “deep learning,” or “artificial intelligence,” or “automatic detection.” Two authors independently extracted data on study characteristics, methods, risk of bias, and outcomes. Any disagreement between them was resolved by consensus.

Results
A total of 16 studies were included in the meta-analysis, which included 5896 chest images from COVID-19 patients. The pooled sensitivity and specificity of the DL models in detecting COVID-19 were 0.95 (95% CI 0.94-0.95) and 0.96 (95% CI 0.96-0.97), respectively, with an area under the receiver operating characteristic curve of 0.98. The positive likelihood, negative likelihood, and diagnostic odds ratio were 19.02 (95% CI 12.83-28.19), 0.06 (95% CI 0.04-0.10), and 368.07 (95% CI 162.30-834.75), respectively. The pooled sensitivity and specificity for distinguishing other types of pneumonia from COVID-19 were 0.93 (95% CI 0.92-0.94) and 0.95 (95% CI 0.94-0.95), respectively. The performance of radiologists in detecting COVID-19 was lower than that of the DL models; however, the performance of junior radiologists was improved when they used DL-based prediction tools.

Conclusions
Our study findings show that DL models have immense potential in accurately stratifying COVID-19 patients and in correctly differentiating them from patients with other types of pneumonia and normal patients. Implementation of DL-based tools can assist radiologists in correctly and quickly detecting COVID-19 and, consequently, in combating the COVID-19 pandemic.
Epistemología en Enfermería. Una revisión del acto de cuidar desde Michel Foucault, el modelo de Roper, Logan & Tierney y el concepto de “bildung” de Gadamer
Authors: Firpo Rosana Elisabet 
Published: March 2021

Desde mediados del siglo pasado el sustento teórico de la disciplina Enfermería se nutrió a través de la elaboración de teorías y modelos de diferente rango y orientación, la mayoría de ellos originados en los Estados Unidos (Henderson, Peplau, Rogers, Leininger, Orem, por citar sólo los más conocidos). De hecho, en la Universidad de Iowa se desarrolló una taxonomía diagnóstica con el propósito de homogeneizar el lenguaje enfermero[1] que al día de hoy cuenta con una importante aceptación a nivel mundial en lo que respecta al desarrollo de los planes de cuidado.
Sin embargo, el intento de imponer esos modelos teóricos en el contexto de América Latina -más que nada por parte de los ámbitos académicos- ha sido muy resistido. A fin de revisar el sustrato filosófico de la adopción de un modelo teórico para la disciplina Enfermería, desde este trabajo se parte de la concepción de persona desde Michel Foucault como ser de vida, trabajo y lenguaje y se recurre al concepto de bildung (Gadamer, 2004) entendido como “edificación” para orientar una necesaria revisión en lo que hace al objeto de estudio y trabajo de la Enfermería.
A partir de hacer énfasis en la persona (familia/comunidad por extensión) destinataria de los cuidados, se propone explicitar la articulación de los tres planos del cuidado a fin de dotar identidad a la disciplina Enfermería al superar el enfoque instrumental y tecnocrático que en general ha teñido a la profesión.
En este camino, se acuerda con Richard Rorty (1979) en la necesidad de mantener el diálogo –en este sentido la taxonomía diagnóstica de la NANDA sería un obstáculo- y se postula un objeto de estudio interdisciplinar que ponga a conversar a las diferentes disciplinas involucradas en el acto de cuidar y se considera que desde el Modelo de Roper, Logan y Tierney, al incluir los determinantes sociales de la salud, es posible tender puentes no sólo hacia la interdisciplina sino además hacia la intersectorialidad.

Published: March 2021

The authors showed that a convenient, accurate and fast way of assessing the degree of influence of environmental factors on plants was needed to optimize photoculture. They emphasized the importance of non-destructive monitoring of crops physiological state of, for which they used phenomics technologies, for example, remote sensing using hyperspectral cameras.(Research purpose) To reveal the possibility of using hyperspectral imaging to determine the plant developmental stability.(Materials and methods) As a measure of the favorable impact of environmental factors on the growth and development of plants, their developmental stability was taken, numerically characterized by the fluctuating asymmetry value. The authors proposed to use vegetation indices determined from the leaf reflection spectra as a bilateral feature. The object of experimental research was juvenile cucumber plants. The studies were carried out in laboratory conditions. The spectral characteristics of cucumber leaves grown under different light quality of radiation were determined using a Specim IQ hyperspectral camera. Information on the spectral reflectances was extracted from the resulting data hypercube. As an example calculations were performed for Normalized Difference Vegetation Index.(Results and discussion) The authors revealed differences in the productivity indicators of plants grown under different light quality. They revealed a significant frequency of occurrence of Normalized Difference Vegetation Index asymmetry in two halves of the cucumber leaf surface. The fluctuating nature of this asymmetry was confirmed. They found that with a light quality providing a higher productivity of plants, lower values of fluctuating asymmetry were observed, which indicate greater stability of plant development.(Conclusions) The authors proposed a method for determining the plant developmental stability using a hyperspectral camera. The method was based on the assessment of the fluctuating asymmetry of vegetation indices calculated for points on the leaf surface, characterized by the same location conditions relative to the border of its left and right halves. A preliminary assessment of the possibility of determining the developmental stability by the results of phenotyping using the example of cucumber plants showed the feasibility of the method and its practical applicability.

The ATmega328 microcontroller was chosen as the main element of the developed microprocessor automated system. The authors created a program for it using visual programming FLProg version 5.3.0.(Results and discussion) The authors found that, regardless of the experiment duration, Galleria mellonella butterflies prefered radiation with 400 nanometers wavelength.(Conclusions) The authors determined that radiation with 400 nanometers wavelength and 10 minutes duration was attractive. They showed the ability to control Galleria mellonella behavior, luring butterflies to a specific place in the beehive with comfortable spectrum parameters. An automated system for controlling the greater wax moth butterfly behavior was developed on ATmega328 microcontroller by implementing attractive optical radiation characteristics.
BNT162b2 Vaccine: possible codons misreading, errors in protein synthesis and alternative splicing's anomalies
Authors: Smith Kira 
Published: March 2021

BNT162b2 vaccine against Covid-19 is composed of
an RNA having 4284 nucleotides, divided into 6
sections, which bring the information to create
a factory of S Spike proteins, the ones used
by Sars-CoV-2 (Covid-19) to infect the host. After
that, these proteins are directed outside the cell,
triggering the immune
reaction and antibody production.
The problem is the heavy alteration of the
mRNA: Uracil is replaced to fool the immune system
with Ψ (Pseudouridine); the letters of all
codon triplets are replaced by a C or a G,
to extremely increase the speed of protein
synthesis; replacement of some amino
acids with Proline; addition of a sequence
(3’-UTR) with unknown alteration.
These impairments could cause strong doubts about the
presence of codon usage errors. An
eventual mistranslation has consequences on
the pathophysiology of a variety of diseases.In
addition, mRNA injected is a pre-mRNA, which
can lead to the multiple mature mRNAs; these
are alternative splicing anomalies,
direct source of serious long-term harm on the human
health.
In essence, what will be created may not be
identical with protein S Spike: just an error in
translational decoding, codons misreading, production
of different amino acids, then proteins, to cause
serious long-term damage to human health, despite
the DNA is not modified, being instead in the cell
nucleus and not in the cytoplasm, where the modified mRNA
arrives.
However, in this case, the correlation between speed of
synthesis and protein expression with synthesis
errors, as well as the mechanism that could affect
the translation of the sequence remain obscure,
many trials have not yet been performed.

Authors: Carvalho Misley Ferreira Viana de , Soares Juliano Lima , Pimenta Daiana Paula 
Published: March 2021

Este estudo aborda a associação entre os princípios de governança corporativa e os fatores da aprendizagem organizacional nos escritórios contábeis brasileiros. Os dados primários foram obtidos por questionários eletrônicos com uma amostra final de 207 escritórios. Este estudo é exploratório, de natureza descritiva, realizado em ambiente de campo e classificado como quantitativo. O grau de governança corporativa obtido de 11,70 sinaliza que a adoção dos princípios de governança corporativa está num estágio intermediário e o grau de aprendizagem organizacional auferido de 8,20 demonstra que o ambiente é propício para a aprendizagem organizacional nos escritórios contábeis. À medida que o grau de governança corporativa evolui, naturalmente, ocorre uma potencialização dos fatores de aprendizagem organizacional, tais como diálogo, interação com o ambiente externo, experimentação e propensão para o risco. Dentre os principais achados desta pesquisa, destaca-se que há um relacionamento positivo entre a adoção dos princípios da governança corporativa e os fatores da aprendizagem organizacional (r=0,244). Quando os níveis de transparência das informações nos escritórios contábeis aumentam, também há um aumento no nível de tratamento justo e equânime entre os sócios e as partes interessadas (r=0,621). Conforme a utilização do diálogo aumenta, como forma de aprendizado, há um aumento na interação com o ambiente externo (r=0,776) e quando sugestões e novas ideias são bem atendidas e aceitas a utilização do diálogo como construção de conhecimentos comuns também aumenta (r=0,722).

Authors: Hussein Dhirgam Allawy Hussein , Mahmood Sahar Jaafar 
Published: March 2021

The articles introduces and investigates "two new subclasses of the bi-univalent functions ." These are analytical functions related to the m-fold symmetric function and . We calculate the initial coefficients for all the functions that belong to them, as well as the coefficients for the functions that belong to a field where finding these coefficients requires a complicated method. Between the remaining results, the upper bounds for "the initial coefficients "are found in our study as well as several examples. We also provide a general formula for the function and its inverse in the m-field. A function is called analytical if it does not take the same values twice . It is called a univalent function if it is analytical at all its points, and the function is called a bi-univalent if it and its inverse are univalent functions together. We also discuss other concepts and important terms. .
Repeatability, reproducibility, and reference intervals for indices of right atrial longitudinal strain derived from speckle-tracking echocardiography in healthy dogs
Authors: Morita Tomoya , Nakamura Kensuke , Osuga Tatsuyuki , Takiguchi Mitsuyoshi 
Published: March 2021

Abstract

OBJECTIVE
To determine repeatability, reproducibility, and reference intervals of indices of right atrial longitudinal strain (RALS) derived from speckle-tracking echocardiography (STE) in dogs without heart disease.

ANIMALS
110 client-owned dogs and 10 laboratory Beagles.

PROCEDURES
To determine intraobserver within-day (repeatability) and interobserver (reproducibility) coefficients of variation, RALS during ventricular systole (εS), ventricular early diastole (εE), and atrial systole (εA), as derived with STE, were obtained by 2 investigators for 5 randomly selected client-owned dogs and analyzed by linear regression. Reference intervals were estimated from the results of all dogs. Correlations between RALS indices (εS, εE, and εA) and sex, age, body weight, heart rate, and blood pressure were determined.

RESULTS
RALS derived from STE showed good intraobserver within-day repeatability and interobserver reproducibility, with coefficients of variation of < 20%. Both εS and εE were significantly negatively correlated with age, but εA was not correlated with age. Indices were not correlated with sex, body weight, or blood pressure.

CONCLUSIONS AND CLINICAL RELEVANCE
RALS indices derived from STE were repeatable and reproducible and were affected by the age of dogs without heart disease. Age should be considered in the interpretation of RALS indices in clinical settings. Further studies are needed to apply RALS indices for assessing dogs with heart disease.

Published: March 2021

Abstract

OBJECTIVE
To evaluate stiffness of the liver parenchyma in healthy adult cats by means of point shear wave elastography (PSWE).

ANIMALS
18 client-owned adult (1- to 6-year-old) healthy cats.

PROCEDURES
Echogenicity and echotexture of the liver parenchyma were assessed by means of conventional B-mode ultrasonography. The shear wave velocity (Vs) of the right and left portions of the liver were measured by means of PSWE.

RESULTS
B-mode ultrasonography revealed no abnormalities in echotexture or echogenicity of the liver parenchyma in any cat. Mean (95% CI) Vs in the liver parenchyma was 1.46 m/s (1.36 to 1.55 m/s) for the right portion, 1.36 m/s (1.26 to 1.47 m/s) for the left portion, and 1.43 m/s (1.35 to 1.51 m/s) overall. The difference in mean Vs between the 2 portions of the liver was significant. No significant correlation was found between Vs and body weight or between Vs and the depth at which this variable was measured.

CONCLUSIONS AND CLINICAL RELEVANCE
Quantitative PSWE of the liver was feasible in healthy adult cats. The obtained values for Vs may be useful for interpretation of and comparison with values measured in cats with liver disease. Additional research is needed to explore the potential usefulness of PSWE for diagnostic purposes.
