Published: September 2021

Este artigo analisa e discute as produções acadêmicas da Educação Física sobre Educação Infantil a partir de uma breve apresentação e análise dos estudos que tomaram tal produção como tema de investigação. Em termos metodológicos se constitui numa revisão integrativa dos artigos, teses e dissertações que se propuseram a estudar a referida produção e estão disponíveis no Portal de Periódicos da CAPES, no Catálogo de Teses e Dissertações da CAPES e na Biblioteca Digital Brasileira de Teses e Dissertações (BDTD). Apresenta uma síntese e análise dos principais aspectos da produção que os estudos nos permitem conhecer, aponta algumas lacunas e indica algumas relações entre os referenciais teóricos que embasam as produções e as proposições apresentadas para a prática pedagógica da Educação com a Educação Infantil que vêm sendo sistematizadas. Conclui que, embora importante, a ênfase dada pelos estudos de revisão e estado da arte aos aspectos quantitativos e descritivos da produção tem dificultado uma compreensão mais abrangente dos discursos que são produzidos sobre a Educação Física na Educação Infantil.
Corpo e gênero nas práticas inclusivas de Ginástica Para Todos na Educação Fí­sica Escolar
Authors: Oliveira Dayane da Silva , De Oliveira Leonardo Mercês , Cardoso Taynara Reges , Iwamoto Thiago Camargo
Published: September 2021

O artigo tem como objetivo refletir e analisar o processo das práticas de inclusão que permeiam a Ginástica para Todos na Educação Fí­sica Escolar, atentando-se as relações sociais de corpo e gênero. A metodologia segue a perspectiva de revisão narrativa, utilizando fontes que discutem sobre a Ginástica para Todos, inclusão, corpo e gênero. A constituição da inclusão ao longo do processo histórico, desvela uma cultura de exclusão/segregação presente na humanidade. Os inúmeros estereótipos e rótulos que estão presentes na imagem do próprio corpo, traduzem uma pseudo representatividade que é mascarada por influências sociais/culturais. Assim como outros conteúdos aplicados na Educação Fí­sica Escolar, a Ginástica para Todos possui o papel de elucidar sujeitos que lutam, resistem e se colocam frente as dificuldades em um contexto seletivo e hegemônico, oportunizando aos participantes uma integração, interação e sociabilidade, sem haver distinção do que é oportuno para os corpos de homens e mulheres. Essa prática possibilita a experiência e vivência sem que haja um reforço dos movimentos que são instituí­dos pela sociedade de acordo com o gênero. Por fim, o conteúdo da Ginástica para Todos é uma das melhores alternativas para Educação Fí­sica Escolar, uma vez que não estimula a segregação de gêneros.

Published: September 2021

O rúmen bovino é uma fonte de microrganismos que realizam a digestão anaeróbia de compostos de carbono. A sua alta atividade celulolítica acelera o processo de partida em reatores anaeróbios, que tende a ser lento e instável, quando realizado sem inóculo. O estudo objetivou avaliar o potencial do uso de rúmen bovino como inóculo de reatores anaeróbios. O teste foi realizado em bateladas sequenciais, escala de bancada, regime estático e com controle de temperatura de 30 °C. Os reatores foram alimentados com uma solução ácidos graxos voláteis de 6000 mgO2 L-1, de DQO e 3 gSSV.L-1 das respectivas biomassas, rúmen bruto, rúmen lavado e lodo de cervejaria. O desempenho da degradação da DQO, a quantidade de metano produzida e a velocidade de produção de cada biomassa foram medidos e analisados. Após o período experimental, observou-se que apesar do rúmen bovino ter maior concentração de sólidos voláteis, a sua produção de metano foi menor, quando comparado ao lodo de cervejaria. Entretanto, o rúmen apresentou melhor desempenho na degradação da DQO. A Atividade Metanogênica Específica (AME) para os rumens lavado e bruto foram nove e quatro vezes inferior ao do lodo de cervejaria, na primeira alimentação. Na segunda alimentação, houve um aumento de 2,4 e 2,7 vezes para o rúmen lavado e o bruto, respectivamente, em comparação com a alimentação anterior. Concluiu-se que o rúmen bovino pode ser utilizado para a inoculação de um reator biológico anaeróbio para a degradação de matéria orgânica e produção de metano como biogás.

artífice e o poeta
Authors: Agnolon Alexandre
Published: September 2021

O presente artigo tem como foco Rufino, poeta grego sobre o qual pouco se sabe, cujos poemas supérstites estão conservados no quinto livro da Antologia Grega ou Palatina. Meu objetivo principal é discutir um certo conjunto de epigramas em que o poeta descreve tipos femininos cujas graças rivalizam com as deusas – em alguns deles, inclusive, o poeta reelabora em chave epigramática o tema do Julgamento de Páris –, com o intento de demonstrar que, ao emular pintores e escultores, Rufino, em seus poemas plástico-eróticos, põe em cena aspectos importantes relacionados à composição artística de um modo geral baseados na emulação, de maneira que, por tudo isso, seus epigramas não seriam somente eróticos, mas comportariam também uma dimensão programática.
Sucessão imperial e legitimidade política na Roma antiga
Authors: Costa Junior Cesar Luiz Jerce da
Published: September 2021

Este artigo tem por objetivo analisar os mecanismos de legitimidade associados ao exercício do poder imperial durante o início do Principado de Nero (54), momento de transição política para um novo governo em Roma. Por não haver regras definidas de sucessão, a legitimidade se constituía como questão fundamental na consolidação do novo principado. O modelo político criado a partir de Augusto e herdado por Nero deixava ambíguo o status do príncipe perante as elites, o que tornava ainda mais imperativa a construção de princípios de legitimação capazes de trazer segurança ao regime. Analisaremos duas formas de legitimidade possíveis nesse contexto: aquela derivada da herança familiar e dependente da ancestralidade, e a que podemos chamar de legitimidade cidadã, inclinada ao republicanismo.

Aims

Controversial data have been published regarding the prognostic role of cardiac troponins in patients who need hospitalization because of coronavirus disease 2019 (COVID-19). The aim of the study was to assess the role of high-sensitivity troponin plasma levels and of respiratory function at admission on all-cause deaths in unselected patients hospitalized because of COVID-19.

Methods

We pooled individual patient data from observational studies that assessed all-cause mortality of unselected patients hospitalized for COVID-19. The individual data of 722 patients were included. The ratio of partial pressure arterial oxygen to fraction of inspired oxygen (PaO2/FiO2) and high-sensitivity troponins was reported at admission in all patients. This meta-analysis was registered on PROSPERO (CRD42020213209).

Results

After a median follow-up of 14 days, 180 deaths were observed. At multivariable regression analysis, age [hazard ratio (HR) 1.083, 95% confidence interval (CI) 1.061–1.105, P < 0.0001], male sex (HR 2.049, 95% CI 1.319–3.184, P = 0.0014), moderate-severe renal dysfunction (estimated glomerular filtration rate  < 30 mL/min/m2) (HR 2.108, 95% CI 1.237–3.594, P = 0.0061) and lower PaO2/FiO2 (HR 0.901, 95% CI 0.829–0.978, P = 0.0133) were the independent predictors of death. A linear increase in the HR was associated with decreasing values of PaO2/FiO2 below the normality threshold. On the contrary, the HR curve for troponin plasma levels was near-flat with large CI for values above the normality thresholds.

Conclusion

In unselected patients hospitalized for COVID-19, mortality is mainly driven by male gender, older age and respiratory failure. Elevated plasma levels of high-sensitivity troponins are not an independent predictor of worse survival when respiratory function is accounted for.
Fertility Projections in a European Context: A Survey of Current Practices among Statistical Agencies
Authors: Gleditsch Rebecca Folkman , Syse Astri , Thomas Michael J.
Published: September 2021

Projection studies have often focused on mortality and, more recently, migration. Fertility is less studied, although even small changes can have significant repercussions for the size and age structure of future populations. Across Europe, there is no consensus on how fertility is best projected. In this article, we identify different approaches used to project fertility among statistical agencies in Europe and provide an assessment of the different approaches according to the producers themselves.

Data were collected using a mixed-method approach. First, European statistical agencies answered a questionnaire regarding fertility projection practices. Second, an in-depth review of select countries was performed.

Most agencies combine formal models with expert opinion. While many attempt to maximise the use of relevant inputs, there is more variation in the detail of outputs, with some agencies unable to account for changing age patterns. In a context of limited resources, most are satisfied with their approaches, though some are assessing alternative methodologies to improve accuracy and increase transparency.

This study highlights the diversity of approaches used in fertility projections across Europe. Such knowledge may be useful to statistical agencies as they consider, test and implement different approaches, perhaps in collaboration with other agencies and the wider scientific community.
Exploratory Assessment of the Census of Pakistan Using Demographic Analysis
Authors: Wazir Asif , Goujon Anne
Published: September 2021

In 2017, Pakistan implemented a long-awaited population census since the last one conducted in 1998. However, several experts are contesting the validity of the census data at the sub-national level, particularly in the absence of a post-enumeration survey. We propose in this article to use demographic analysis to assess the results of the 2017 census at the sub-national level, using data from the 1998 census, from all available intercensal surveys, including three rounds of Demographic and Health Survey. Applying the cohort-component method of population projection, we subject each five first-level subnational entities to estimates regarding the level of fertility, mortality, international, and internal migration derived from the analysis of the existing data. We arrive at approximately similar results as the census at the national level: an estimated 210 million (95% CI: 203.4–218.9) compared to 207.8 million counted (1.1% difference). However, we found substantial sub-national variations. While there are too many uncertainties in the data used for the reconstruction to be fully confident about them, this analysis should prompt the national and the international community to ensure that a post-enumeration survey and demographic analysis are regular features of census operations of Pakistan in particular, and in developing countries with deficient data as a whole.
A Simulation Study of Diagnostics for Selection Bias
Authors: Boonstra Philip S. , Little Roderick J.A. , West Brady T. , Andridge Rebecca R. , Alvarado-Leiton Fernanda
Published: September 2021

A non-probability sampling mechanism arising from nonresponse or non-selection is likely to bias estimates of parameters with respect to a target population of interest. This bias poses a unique challenge when selection is ‘non-ignorable’, that is, dependent on the unobserved outcome of interest, since it is then undetectable and thus cannot be ameliorated. We extend a simulation study by Nishimura et al. (2016) adding two recently published statistics: the ‘standardized measure of unadjusted bias’ (SMUB) and ‘standardized measure of adjusted bias’ (SMAB), which explicitly quantify the extent of bias (in the case of SMUB) or nonignorable bias (in the case of SMAB) under the assumption that a specified amount of nonignorable selection exists. Our findings suggest that this new sensitivity diagnostic is more correlated with, and more predictive of, the true, unknown extent of selection bias than other diagnostics, even when the underlying assumed level of non-ignorability is incorrect.
Gender Relations and Female Agency in Claire Keegan’s Antarctica
Authors: Morales-Ladrón Marisol
Published: September 2021

Claire Keegan is one of the most prominent voices within the contemporary Irish short story panorama. Internationally acclaimed, her prose has been praised for its frank and bitter portrayal of a rural world, whose outdated values, no matter how anchored in the past they might be, still prevail in a modern milieu. Keegan’s unsympathetic views on society, mainly on the Catholic Church and the family, are the main targets of her harsh criticism. Issues like gender and sexuality, two social constructs with which to validate an uneven distribution of power, constitute the pillars of most of her plots. Bearing these aspects in mind, my proposal focuses on the analysis of Keegan’s first collection of short stories, Antarctica (1999), in light of gender relations and female agency, in an attempt to find patterns of – often thwarted – female emancipation in the context of the rapid changes of a society that is still adjusting to a globalised world. This article will also engage in the discussion of her second collection, Walk the Blue Fields (2007), and her long short story Foster (2010).

Published: September 2021

Budget refocusing becomes a problem when program activities cannot be realized according to the target. The effect is to affect the volume of employees to work. Facing this, it is very important to see how ASN can work optimally in the midst of budget constraints. This study looks at the dimensions of qualification, competence, performance and discipline. The purpose of this study is to find out how the performance of ASN in the face of budget refocusing by looking at the four dimensions. The method is descriptive qualitative, the respondents come from elements of the central government and local government which are recorded in the goggle form application. The results of the study were analyzed that the qualification dimension relates between education and class, the competency dimension measures the competence of ASN from their position, the performance dimensions of respondents who already know refocusing information are 66.53% and 62.50% are of the opinion that budget refocusing affects performance, and 81.65 % approve the refocusing policy. The discipline dimension talks about activity planning, independent study and work innovation. The findings of the study are First, ASN continues to carry out activities as usual even though refocusing has been carried out, Second, ASN productivity is shown by budget realization and achievement of fulfilling annual credit scores for researchers, Third General functional officials carry out action plans in dealing with the situation by shifting non-priority activities into activities  that are output based. The suggestion is that the first is integrated managerial planning, the second is output-based research. The third is realizing comprehensive work innovation. Thus the achievement of the institution and the target of the institution will be achieved without reducing its usefulness.

The active dynamic vibration damper in non-stationary operation of a vibroactive unit
Authors:   Omsk State Technical University, Sitnikov D. V. , Burian A. A. ,   Omsk State Technical University
Published: September 2021

The paper considers a vibration isolation system, in which a force is applied to the moving mass of the active dynamic vibration damper by an actuator in proportion to the measured value of the base response. The amplitude-frequency and impulse characteristics are plotted depending on the parameters of the system, assuming the actuator without distortion generates the force proportional to the base response. It is shown that the considered vibration isolation system is quite effective in the low-frequency region, including in the resonance region of the passive system, both in stationary and nonstationary modes of vibroactive forces

Two main factors are considered that determining the friction between non-lubricated surfaces of an elastomer and a solid base during their relative motion. The first one is adhesion in the areas of real (actual) catalysis and the second factor is the deformation component, which is due to the delay of recovery of the elastomer after the irregularity is introduced and it is called the hysteresis component of friction. One of the main problems of increasing the resource of pneumatic dampers is minimizing the wear of the covering layer of the rubber-cord casing (RCC). The wear of the RCC is due to the fact that sliding friction occurs in the process of contact between the metal surface and the surface of the RCC, as a result of which the cover layer of the RCC (in some cases with the first cord layer) wears out, depending on the chemical composition of the rubber and the features of the operation of the pneumatic shock absorber. In order to minimize the wear of rubber, it is proposed to change the design of the pneumatic damper so that rolling friction dominates in the contact between the surfaces of rubber and metal

The increased requirements for the quality of natural gas transported and used in industrial and domestic purposes have significantly increased the role of the analytical laboratory in the production process, since if the results of analyzes that determine the quality of products depend on the entire work of the gas transportation company as a whole, then the quality and reliability of the analysis results themselves are determined by the work of the testing laboratory. The basis of consumer confidence in the purchased products is ensured by the reliability of confirmation of the conformity of products established in the requirements of technical regulations and standards. Confirmation of the quality of products constantly requires the analytical laboratory to implement methods and techniques for monitoring the quality of analyzes. The research base is Gazprom Transgaz Kazan LLC, one of the gas transmission subsidiaries of Gazprom PJSC serving the Uzhgorod and Novopskov gas trunkline corridors, the Nizhnyaya Tura–Perm–Gorky 1,2 gas pipelines, Orenburg–Zainsk, Kazan–Nizhny Novgorod, etc. The object of the study is the analytical control of the quality of natural gas, the subject is organizational and methodological issues for its implementation. This article proposes a method for calculating the frequency of gas sampling using automated algorithms taking into account data on changes in the composition and properties of gas streams for the reporting period. The description of the method is presented on the example of calculating the frequency of determining the calorific value of the lowest (actual calorific value) and density of natural gas. The central chemical-analytical laboratory of the Gazprom Transgaz Kazan’s engineering and technical center and the points of gas sampling at the gas distribution stations of the main gas pipelines in the service area of the сompany are used as objects of the method implementation

The paper considers the possibility of constructing a magnetic field strength gradient meter based on the absolute helical instability of electron-hole plasma of a semiconductor sample. The functional scheme of the gradiometer and the results of experimental and theoretical studies of the sensitive element of the gradiometer are presented
Expansion of dynamic range of sampling and storage device by weight integration of narrow-band oscillation
Authors:   Omsk State Technical University, Zhenatov B. D.
Published: September 2021

The most bottleneck of high-frequency digital radio receivers in terms of dynamic characteristics is the process of analog-to-digital conversion. Most often, to meet the requirements for the speed and dynamic range of the analog-to-digital conversion, a sampling and storage device (UHF) is included in front of the analog-to-digital converter (ADC), which is significantly simpler in structure than the ADC structure, but reduces the requirements for its speed and dynamic range [1, 2]. A method for expanding the dynamic range of the integrating sampling and storage device for digital radio receivers using the weight integration of the input narrow-band oscillation is proposed

Published: September 2021

The article discusses the principles and possibilities of using jet-drop optical measuring systems for monitoring the electric field strength (EFS). Two applied techniques are considered. First, the deflection of flying charged droplets (balls, hollow granules) used as micro-objects sensitive to EFS and deviating from a given rectilinear trajectory of motion, like an electron in a kinescope. Secondly, stroboscopic determination of the position and/or displacement of drops by pulsed illumination of the side of the deflected drop by the optical flow and measurement of the reflection angle for it. The possibilities of implementing the differential method of EFS measurements are discussed. The features of the use of liquids with the addition of metal nanopowders or based on liquid metals, as well as hollow droplets in the form of microspheres or hollow granules are considered

Background. Currently, cardioanesthesiology is one of the most actively developing areas of modern medicine. Thanks to new methods of treatment, the contingent of patients for whom it became possible to undergo cardiac surgery has significantly expanded. The main problems that lead to hemodynamic complications are endothelial dysfunction and cellular hypoxia. Purpose. To present data on the influence of clinical and laboratory factors of endothelial dysfunction and cellular hypoxia on the development of hemodynamic complications during anesthesia in cardiac surgery. Material and methods. The review and analysis of literature data from 49 sources is presented. Results. The laboratory markers of endothelial dysfunction leading to the development of major hemodynamic complications in cardiovascular diseases are MPC-1, CRP, NO, TNF-α, IL-6, homocysteine. Conclusion. The data obtained indicate a significant effect of cell markers (MPC-1, CRP, NO, TNF-A, IL-6, homocysteine) as well as clinical and laboratory factors of endothelial dysfunction not only on the development of major diseases of the cardiovascular system, but also on their complications. An early study of these markers can improve anesthesia during cardiac surgery as well as reduce complications in the postoperative period.

Published: September 2021

Background. The treatment of phlegmon of the maxillofacial area and neck at the present moment remains difficult and insufficiently effective. Aim. To develop a method of using photodynamic therapy (PDT) for the treatment of phlegmon of the maxillofacial area and neck and to evaluate its effectiveness. Material and methods. A total of 92 patients with phlegmons of the maxillofacial area and neck were under observation. They were divided into 3 groups: group 1 – “control group 1” (30 patients) – where traditional treatment was used, group 2 – “control group 2” (30 patients) – in which low-intensity laser radiation was used in addition to topical treatment and group 3 – “experimental” (32 patients) – where PDT was used for topical treatment. Results. The data of clinical, cytological and bacteriological studies show that the local application of PDT has an anti-inflammatory effect and stimulates the reparative processes in the wound, and shortens the treatment period for patients. Conclusion. PDT improves the results of complex treatment of patients with phlegmons of the maxillofacial area and neck. Its application leads to the purification of a purulent wound on the 3rd (3;4) day, allows to apply secondary sutures on the 7th day and to shorten the period of inpatient treatment in comparison with the control groups from 3 to 9 days.

Published: September 2021

Background. Transabdominal gastroesophageal devascularization is a technically feasible backup operation for most general surgeons in case of failure of endoscopic prophylaxis of bleeding from esophageal varices. There is an emerging trend in the development of laparoscopic technologies in the surgical correction of complications of portal hypertension. Purpose. Assessment of the clinical efficacy of laparoscopic esophagogastric devascularization in its own modification. Material and methods. In the period from 2009 to 2020, the results of treatment of 31 patients were studied. The patients were divided into 2 groups by the method of simple randomization. In the control group, surgery was performed in a standard way, in the main group - in the modification we proposed. Results. The use of our proposed technological methods when performing the stage of transection of the abdominal esophagus during laparoscopic esophagogastric devascularization in its own modification reduced the frequency of technical difficulties at this stage, which caused conversions, anastomotic leakage and other intra and postoperative complications. In the long-term period, there was a decrease in the degree of esophageal varices, a decrease in the frequency of recurrent bleeding and mortality, as well as an improvement in the quality of life in patients after a modified operation in comparison with the standard technique. Laparoscopic esophagogastric devascularization in our modification shows better results as a method of secondary prevention of bleeding from esophageal varices in cirrhosis of the liver in patients with a high risk of recurrence than the use of endoscopic sclerosis of esophageal varices, is characterized by a lower incidence of repeated episodes of bleeding from esophageal varices and less lethality. Conclusions. Based on the analysis of the immediate and long-term results of the use of laparoscopic esophagogastric devascularization in its own modification in the clinic, it should be noted the reproducibility of the surgical intervention, its effectiveness and safety.

Background. Cystic lesions of the spleen are not an uncommon pathology, however, until now clear criteria for the scope of surgical interventions are not clearly defined and depend on a number of anatomical and clinical features of this pathology, and laparoscopic resection is still a surgical challenge. Purpose. Preliminary analysis of the results of laparoscopic resection of spleen cysts, as well as the study of the current literature on the subject. Material and methods. This article presents a clinical case from the authors' personal experience with the diagnosis and treatment of a patient with a spleen cyst. Laparoscopic method was used in surgical treatment. In selecting it, a number of relevant medical literature was studied and analyzed. Results. As a result of a successful laparoscopic resection the patient managed to save such an important organ for homeostasis maintenance as the spleen. Postoperative complications were also avoided. Conclusions. Organ-preserving and minimally invasive interventions should remain the priority at the current stage of surgery development. In the treatment of such pathology as spleen cysts, planned approach is preferable, which allows for maximum preoperative diagnosis. It should take into account the etiology and localization of the cyst, as well as the peculiarities of blood supply to the spleen in a particular patient.

Home dialysis and Covid-19 in french speaking countries (RDPLF data-base)
Authors: Verger Christian , Fabre Emmanuel , Durand Pierre-Yves , Chanliau Jacques , Vernier Isabelle , Dratwa Max
Published: September 2021

Aims of the study: to assess the frequency of symptomatic Covid-19 in home dialysis patients and its influence on the number of patients treated at home in dialysis units of centers included in the French-speaking peritoneal and home hemodialysis Registry (RDPLF). Focus is placed on patients treated by peritoneal dialysis (PD) in mainland France.

Results: in home hemodialysis (HHD)the incidence is 6% in Belgium and 4.8% in mainland France. On peritoneal dialysis it is 10.6% in Belgium, 6.7% in mainland France, 10.8% in Morocco and 11.5% in Tunisia. Lethality is less than 5% in HHD and between 8.4% and 42.7% in PD depending on age and associated comorbidities. In France, the percentage of patients who have had symptomatic Covid-19 is lower on home dialysis, all methods combined. Nevertheless, among the home methods, the higher frequencies and severities are observed in mainland France in home assisted PD: these are the oldest and most co-morbid patients. Transfers from PD to in center hemodialysis have increased during Covid-19 pandemic while the number of transplants has decreased.

Conclusion: if the drop in the number of transplants can be explained by a reduced availability of operating theaters and surgical teams during a pandemic period, it is paradoxical that the prescription of home dialysis, which should be supposed to limit the risk of contagion, has decreased. More investigation should be performed to understand this paradox.

Authors: Adham Zeina  S , Al-Ghurabi Batool  H
Published: September 2021

Background: In December 2019, an episode of COVID-19 caused by severe acute respiratory syndrome coronavirus 2 (SARSCoV2) was reported in Wuhan, China and has spread around the world, increasing the number of contagions. Cytomegalovirus (CMV) and Epstein-Barr virus (EBV) are common herpesviruses that can cause persistent latent infections and affect the developing immune system.The study was conducted to explore the prevalence and reactivation of CMV and EBV antibodies in COVID-19 patients group in comparison to healthy group and to investigate the association between the presence of these viruses with each of severity of disease and oral hygiene. Materials and Methods: Eighty Five subjects were participated in this case control study (50 patients with COVID-19 and 35 healthy controls), their age range from 18 to 77 years. Oral health status was established by oral hygiene index. Serum obtained from patients and controls was analyzed using ELISA to assess levels of anti- CMV and anti- EBV antibodies. Results: The study revealed that the mean of anti-EBV IgG in patients was significantly elevated (p<0.01) than that in controls. Otherwise, there was no significant difference (p>0.05) in levels of anti- EBV IgM, anti- CMV IgG and IgM between two groups (P>0.05). In addition there were no significant differences between patients and controls (p>0.05) in the number and percentage of anti-EBV and anti-CMV antibodies. Interestingly, there was a significant increase in the level of anti-CMV IgM in severe cases as compared to mild cases, (P<0.01). Furthermore, these results revealed that there were no significant differences (P>0.05) in levels of anti-viral antibodies in patients with good oral hygiene compared to patients with poor oral hygiene. Conclusions: Higher frequency of anti-EBV IgG among patients indicates that latent infection is more common in COVID-19 patients. While an increased percentage of anti-CMV IgM indicated reactivation of latent infection and is related to disease severity suggesting that COVID-19 can cause cellular immune impairment.
