Abstract
Objectives

The aim of the study is evaluate the association of obstructive sleep apnea syndrome (OSA) and vitamin D deficiency (VDD) in shift workers.
Methods

This cross-sectional study included rotating shift workers in an iron ore extraction company. Participants were classified as VDD when 25(OH)D < 20 ng/mL for a healthy population and 25(OH)D < 30 ng/mL for groups at risk for VDD. Risk of developing OSA classified by Berlin Questionnaire (BQ) and NoSAS score. Data were compared using chi-square analysis with Cramer's V as effect size, and Bonferroni correction. Multivariate logistic regression analysis was performed to investigate whether VDD was associated with OSA risk assessment.
Results

Among 1461 workers, mostly male (97.4%), younger, aged 30 to 39 years (53.9%), worked shifts for more than 5 years (75.8%). A prevalence of high risk of OSA by BQ was 15.9%, and 32.5% by NoSAS score. Besides, 28.9% had VDD. In multivariate analysis, controlled for confounding factors, workers with VDD had a 79% increased chance of OSA by BQ (OR: 1.79; CI95%: 1.27-2.51) and an 85% increased chance of OSA by NoSAS score (OR: 1.85; CI95% 1.35-2.53). After subgroup analyses, similar results were not observed in workers aged 20-29 years.
Conclusion

Rotating shift workers with vitamin D deficiency are more likely to have obstructive sleep apnea, assesed by Berlin questionnaire and NoSAS score.

Introduction: in 1968, Altman developed a multivariable predictive Z-score model to assess the probability of a public manufacturing company going to bankruptcy based on financial ratios. Later, Altman (1983) re-stated a more improved Z’’-Score model designed to apply in public or private, manufacturing, or non-manufacturing firms, but also in emerging countries. Prediction of the updated model proved to be highly efficient. This research was conducted to prove the level of accuracy of the Z’’-Score model applied to firms listed in the Mexican Stock Exchange (MSE) since there is little relevant research on this subject.
Method: this research was conducted under a quantitative approach as a census and its scope was situational with a non-experimental and longitudinal research design. The period covered by this research was 2012-2019 since the data was available for those years under a somehow stable economic situation without significant economic ups and downs. This research considered the integration of a large financial database and the design of a typology to classify and analyze 155 firms based on a standard deviation and average results of 837 Z’’-scores. A second analysis was conducted to prove if the predicted situation (area) by the Z’’-Score corresponded to the real situation in the marketplace for every company.
Results: the results showed that the accuracy level of the Altman model decreased when applied to Mexican firms. The error of the model applied to Mexican companies related to those classified in the bankruptcy prediction area was 75 % of misclassification cases. The total error of the model included all areas, or cases, was 18 % of misclassification cases. This model is supposed to be effective within a time frame of two years before a possible bankruptcy. Even considering a longer time frame, the companies located in the bankruptcy prediction area continued having misclassifications representing 57 % of error. The error for the model considering all cases and all areas, was 14 % of misclassification cases. This represented a high level of inefficiency of the model applied to an emerging country companies, such as Mexico.
Discussion or conclusion: the model is certainly effective while predicting companies in the areas of non-bankrupt sector and grey, but it was inefficient when predicting the possibility of bankruptcy. It was also demonstrated that the time frame of two years is no longer effective when applying the model to Mexican companies. As a result, more research cases are needed to update the model to perform efficiently in emerging countries including country-specific conditions and considering a different time frame to predict bankruptcy.

Published: November 2021

Based on the theoretical results obtained in the article [17], here the analysis of the influence of various design parameters on the own weight and cost of metal of truss beams with two posts is carried out. An optimal parameter has been obtained that makes it possible to reduce the calculated bending moment in the cross section of a truss beam with two struts.Method. By equalizing the bending moments in various design sections of the truss beam, the internal force factors are reduced. The corresponding equation for optimizing the parameters of the beam has been drawn up and a formula has been obtained to determine the optimal parameter of the structure as a whole.Result. Using the example of numerical calculations, a decrease in the calculated bending moment by 14% compared to truss beams without optimization is shown.Conclusion. The proposed method and algorithm testify to the efficiency and rationality of the obtained optimal parameter of the structure as a whole.

Este ensaio pretende discutir a questão da hermenêutica de Martin Buber em sua relação a arte. Nosso ponto de partida é a relação Eu-Tu como caminho para uma hermenêutica espiritual. A seguir discutiremos a questão da relação entre hermenêutica e arte no pensamento de Buber e, por extensão, a questão da relação dialógica com as esferas da natureza e dos objetos. Será abordada, ainda, a questão do que Buber designa por “a graça da unidade”, momento de encontro da alma com de Deus e, o seu inverso, o momento do caos experienciado pela alma. Para tal se escutarão as vozes de Czeslaw Milosz, Simone Weill, Paul Tillich, Milan Kundera e também de Dostoievski, interpretadas sob o viés buberiano. Concluímos com a hipótese de que é possível, a partir do horizonte hermenêutico fornecido pelo pensamento buberiano, se pensar acerca de uma concepção de hermenêutica espiritual de caráter dialógico.

Unequal patient assignment is a problem of nursing students during clinical practicum. Registered nurses use patient acuity to ensure balanced work distribution, but its benefits has not been assessed on student nurses to date. The study’s objective is to determine the effect of patient acuity tool on student nurses’ satisfaction level during practicum. The study utilized quasi-experimental design to level II and III nursing students at a University in Quezon City, Philippines. 6-Module Online course including videos, notes, and quiz using Google Classroom was used; orientation and simulation were conducted through Zoom and Facebook Messenger. The participants were tasked randomly to use Patient Acuity Tool or conventional method during patient distribution. A modified Kuopio University Hospital Job Satisfaction Scale was used to identify and compare satisfaction levels of the two groups. Descriptive and Independent Samples T-test using Statistical Package for the Social Sciences version 26 were used to analyze data. Requiring factors, motivating factors, and working welfare of students utilizing Patient Acuity Tool are higher in overall mean satisfaction rate (3.36, 3.71, 3.89 vs 3.57, 3.81, 3.91); however, mean satisfaction showed no significant difference based on indicators (p-value 0.372, 0.694, 0.052, 0.921, and 0.469) and overall satisfaction (p-value 0.947). The requiring factors of work reflects the lowest mean scores given by those who have used the Conventional Method focusing on number of staff (2.97) and even workload distribution (2.14).

Abstract

CASE DESCRIPTION
A 3-year-old 31.1-kg castrated male mixed-breed dog was evaluated because of a 1- to 2-week history of paraparesis, knuckling of the hind feet, and difficulty posturing to urinate or defecate.

CLINICAL FINDINGS
The dog was paraparetic but weakly ambulatory with a kyphotic posture, a mildly decreased patellar reflex in the right pelvic limb, increased tone in both pelvic limbs, and marked hyperesthesia on paraspinal palpation of the lumbar region. The urinary bladder was enlarged and firm on palpation. Neuroanatomic findings were primarily consistent with localization to the T3-L3 spinal cord segments. Magenetic resonance imaging of the thoracolumbar spinal column revealed a discrete intramedullary spinal cord mass from the cranial aspect of L4 to the middle of L5. The mass was sampled by fine-needle aspiration, and on cytologic evaluation, the suspected diagnosis was an ependymoma.

TREATMENT AND OUTCOME
Owing to poor prognosis and limited treatment options, the owner elected euthanasia. Postmortem examination of the spinal cord and histologic findings for samples of the mass supported a likely diagnosis of ependymoma.

CLINICAL RELEVANCE
Ependymoma is a rare neoplasm in dogs but should be considered in young patients with evidence of a tumor in the CNS. Fine-needle aspiration of the spinal cord mass was possible in the dog of this report, and the cytologic findings provided useful diagnostic information.

Abstract: This paper presents the idea of Trostksyms in George Orwell’s Animal Farm. While critics often portray Orwell as anti- communist due to his critiques on the character Napoleon as the representation of Stalin. On the other hand, this paper describes that Orwell through the character Snowball shows great sympathy on Snowball. This paper describes that Snowball is the portrayal of Trostky.
