On-site communication skills education increases appointment-specific client satisfaction in four companion animal practices in Texas
Authors: Janke Natasha , Shaw Jane R. , Coe Jason B.
Published: August 2022

Objective

To assess the impact of a 15-month, in-practice communication skills intervention on client visit satisfaction.

Sample

4 purposely selected veterinary clinics, 9 veterinarians, and 930 appointment-specific client satisfaction surveys.

Procedures

The study was designed as a multipractice, preintervention-postintervention study. Practice teams participated in a 15-month communication skills intervention that included interactive group workshops and one-on-one communication coaching with the entire practice. Client Satisfaction Questionnaires were completed 3 months before (mean, 55 questionnaires/veterinarian) and after (mean, 48 questionnaires/veterinarian) the intervention. The impact of the intervention and factors associated with client visit satisfaction were evaluated with mixed logistic regression.

Results

Client satisfaction scores were dichotomized owing to extreme negative skewness. In total, 57% (284/496) of clients were completely satisfied on pretest questionnaires, and 67% (290/434) were completely satisfied on postintervention questionnaires. The odds of clients being completely satisfied were significantly higher after the communication skills intervention (OR = 1.56; P = .002). When controlling for the intervention, predictors of client visit satisfaction included appointment type (odds of being completely satisfied were significantly higher for recheck appointments than for preventative care appointments [OR = 1.71; P = .02] and health problem appointments [OR = 1.99; P = .003]) and duration of the veterinarian-client relationship (probability increased by 0.52 with each 1-year increase in relationship duration; P = .008).

Clinical Relevance

Results suggested that the client-centered, skills-based communication intervention resulted in increased client visit satisfaction. Findings contribute to current evidence that client-centered communication and duration of the veterinarian-client relationship promote client satisfaction during veterinary visits.
Kladenští type as a problem of automatic morphological analysis
Authors: Osolsobě Klára , Žižková Hana
Published: August 2022

The aim of our paper is to demonstrate the procedures by which the data needed to refine tools for automatic morphological analysis of Czech can be obtained using a corpus, namely the Araneum Bohemicum IV Maximum (Czech, 20.03) 7.10 G web corpus of the ARANEA series and Araneum Bohemicum Maximum (Czech, 15.04) 3,20 G (hereinafter Araneum). Particularly, we will focus on propria of the Kladenští type, i.e., substantivized adjectives of denoting groups of persons according to affiliation. The goal of the probe into the Aranea web corpus is: 1) a corpus-based description of frequented properties of the Kladenští type, which can be used as a starting point for rule disambiguation; 2) creating a list of the most frequent lemmas belonging to the Kladenští type, which can then be included into dictionaries of automatic morphological analyzers (e.g. the MorfFlex dictionary by Hajič and Hlaváčová). We believe that the probe can help improve the results of tools for automatic morphological analysis of Czech.

Comparative Corpus-Driven Study of Prepositional Semantics in Russian and Czech
Authors: Zakharov Victor
Published: August 2022

This paper deals with prepositions with causal meaning in Russian and Czech. In Slavic languages prepositions are closely connected to cases. Russian and Czech prepositions have many common features. Prepositions show a relation in space or time or a special relationship between two or more people, places, things or situations. In the current paper we are dealing with causal relations. There are different ways to express them. Among these means, the most common are prepositional-case forms and complex sentences with a subordinate causal part. We analyze the repertoire of causal prepositions in both languages and describe their statistical representation in corpora. Another task is to reveal translation equivalents between two languages.

Published: August 2022

Objective: Obesity is a worldwide concern that may lead to type 2 diabetes, cardiovascular diseases, etc. Several serum biomarkers have been identified in the saliva of obese individuals, including inflammatory cytokines, adipokines, insulin, and cortisol. The present study aimed to compare salivary interleukin-6 (IL-6), interleukin-8 (IL-8), C-reactive protein (CRP) levels and total antioxidants capacity (TAC) of obese individuals with normal-weighted ones.

Methods: In this case–control study, 92 participants matched in terms of age and gender were placed into two groups according to the body mass index (BMI); case group: BMI>30 and control group: 18.5<BMI<24.99. Unstimulated saliva was collected. ELISA and FRAP method were used to determine IL-6, IL-8, CRP and TAC. Data was analyzed using SPSS 24, at the significant level of 0.05.

Results: Mean salivary levels of IL-6 and IL-8 in the normal individuals were 53.36 and 421.25ng/mL, with 86.09 ng/mL and 510.19 ng/mL in obese individuals, respectively. There were significant differences in the mean salivary levels of IL-6 and IL-8 between two experimental groups.

The mean salivary levels of CRP of control and case group was 2.84 and 2.63 ng/mL and the total salivary antioxidant levels in the normal and obese individuals were 0.29 and 0.36, respectively which had no significant different.

Conclusion: According to the results of the present study, salivary levels IL-8 and IL-6 was significantly higher in obese individuals than in those with normal weight. However, the mean salivary CRP and TAC were not significantly different between the obese individuals and normal-weighted ones.

Angiotensin 2 impairs vascular function by activation of reactive oxygen species (ROS) production and development of endothelial dysfunction. Metformin, the first-line therapeutic agent for type 2 diabetes mellitus, has vascular protective properties, beyond its glucose lowering effects. The aim of the present study was to investigate the interaction between metformin and angiotensin 2 in human internal mammary arteries harvested from patients with coronary heart disease undergoing revascularization procedure, by evaluation of vascular function, reactive oxygen species (ROS) production and the gene expression of nitric oxide (NO) synthases (endothelial – eNOS, neuronal – nNOS and inducible – iNOS). To this aim, vascular samples were incubated with angiotensin 2 (Ang2, 12 h) with/without metformin (Metf, 10 μM) and used for ROS measurement (FOX assay), vascular reactivity in organ bath (contractility to phenylephrine, relaxation to acetylcholine, contractility to NG-nitro-L-arginine methyl ester/L-NAME) and RTPCT studies. Acute incubation of the vascular rings with Ang2 impaired vascular reactivity (increase contractility, decrease relaxation), increased ROS production, supressed eNOS/nNOS and increased iNOS mRNA expression. Ex vivo incubation with metformin at a clinically relevant concentration reversed all these effects. These data suggest that Metformin might be useful in alleviating endothelial dysfunction by improving the endothelial-dependent relaxation and mitigating oxidative stress in clinical setting associated with cardiovascular disease regardless the presence of impaired glucose metabolism.
Comparison of Czech and Slovak Railway Infrastructure in the Context of Basic Operational Indicators
Authors: Židová Zuzana , Čamaj Juraj
Published: August 2022

The level of development of railway transport is one of the indicators of the economic development of the state. If the state regularly invests in large volumes in railway infrastructure, it creates conditions for the operation of quality passenger and freight rail transport. Analytical comparison of railway infrastructures is key to understanding the increasingly abysmal differences between the quality of railway infrastructure in the two countries. The comparison will be made mainly from the Network Statement of both countries.

Published: August 2022

The current study hypothesized that the status of a professional American football player would influence how observers perceived his weeping after losing a game. It was also predicted that the importance of the game (the NFL Super Bowl vs. a regular season game) would influence perceptions of his tears. Two hundred twenty-two adults, recruited nationally, read 1 of 4 vignettes in a 2 (player status: high- or low-performing) x 2 (game status: Super Bowl or regular season game) between-subjects design. The vignette describes a close game that is ultimately lost by the target’s team, with the target weeping at its conclusion. Participants (N = 213) rated his postgame weeping as more appropriate and justifiable, using an allowance composite score, as it was found that there was a significant difference for both player, F(2, 196) = 10.13, p < .001; Wilks’ Lambda= .91; η2 = .09, and game, F(2, 196) = 4.27, p = .02; Wilks’ Lambda = .96; η2 = .04, status. There were also significant differences found in analyses for player status on perceived emotional stability, F(1, 202) = 20.22, p < .001, η2 = .09, and game status on perceived competency, F(1, 200) = 173.63, p < .001, η2 = .47. The ramifications of these findings, that situational details and personal attributes of the target influence observers’ judgments of emotional appropriateness, are discussed.

Urbanización informal y ciudad desigual, controversias territoriales en una localidad de León, Guanajuato.
Authors: Gasca Moreno Claudia Teresa , García Gómez Miguel Ángel
Published: August 2022

El objetivo de este trabajo es analizar la dinámica de urbanización informal y su configuración territorial como resultado de políticas neoliberales que inciden en la forma en que crece y se expande la ciudad. Se trata de una primera aproximación al caso de San Juan de Abajo, una localidad periurbana de la ciudad de León, Guanajuato que se origina como respuesta a una demanda de vivienda de población de bajos ingresos que vive al margen de mecanismos que le permitan acceder al espacio urbano formal. A través de una revisión documental, examinamos su origen como asentamiento informal precarizado y con ayuda del método etnográfico exploramos su configuración, describimos el entorno urbano y las principales problemáticas que enfrentan sus habitantes en el cotidiano, los resultados muestran que este asentamiento no solo es consecuencia de una expansión no planeada sino materializa la desigualdad urbana que enfrenta la población de bajos ingresos que encuentra en la informalidad una oportunidad de habitar la ciudad.

Published: August 2022

Durante los meses de mayo y junio de 2021 se produjo en Colombia un inmenso estallido social, sin antecedentes en la vida del país, que puso en tensión la vida colectiva. La expresión más fuerte de este fenómeno se presentó en la ciudad de Cali, donde se movilizaron numerosos sectores de la población, con la participación sobresaliente de los jóvenes. Las ciencias sociales en Colombia, así como ha ocurrido a nivel internacional con el movimiento parisino de Mayo de 1968, girarán durante mucho tiempo alrededor de la investigación y la interpretación de lo sucedido durante estas semanas. Un grupo de profesores de la Facultad de Ciencias Sociales y Económicas, de la Universidad del Valle de Cali, hicimos un seguimiento al detalle de lo que estaba ocurriendo en nuestro entorno, al calor de los acontecimientos, y este libro recoge las principales contribuciones, desde la sociología, la economía, la ciencia política, la comunicación social, las teorías del género. Somos conscientes de que estos ensayos se pueden convertir en un punto de partida fundamental para estudios posteriores, a pesar de que lo expuesto en ellos es aún provisional y sujeto a desarrollos posteriores. Hemos tratado de mostrar la manera como los acontecimientos se inscriben en la coyuntura del Paro nacional, decretado en ese momento por diversas organizaciones sociales y sindicales, pero igualmente nos hemos enfocado en el estudio de lo acontecido de manera particular en la ciudad de Cali y su región metropolitana, y en las movilizaciones de apoyo que se presentaron en países con presencia de migración colombiana. Con este esfuerzo hemos querido responder a una de las tareas básicas de la Universidad pública, como es la contribución al mejor entendimiento de lo que nos ocurre, como punto de partida para proponer caminos que permitan superar los retos del presente.
Above-the-Horizon Coverage for Satellite Constellations with Dual-Altitude Band Constraints Using Ring-Based Discretization
Authors: Sun Yangyuxi , Wen Changxuan , Zhang Chen , Zhu Zhengfan , Ye Zhao
Published: August 2022

For observation against a space background, satellite constellations, as a complement to traditional ground-based observation systems, have advantages in flexibility and observing performance, especially for very small space objects. The coverage of this kind of constellation is a typical above-the-horizon (ATH) problem. This study focuses on the three-dimensional ATH coverage for satellite constellations with dual-altitude band constraints and a prespecified sensor range. A rapid coverage calculation method is first developed for a single satellite by discretizing the target region into ring elements of equal volume. This treatment significantly reduces the computational load because the angular coverage interval of the centerline of each ring element can be analytically derived. The method is then extended to satellite constellations by using the superimposing law along the centerline. In this manner, both the onefold and multifold coverages of the constellation can be determined. Finally, a comprehensive comparison with existing models is performed, demonstrating the effectiveness and computational efficiency of the proposed method.

Published: August 2022

Objetivo: Analisar como a Infecção pelo Papilomavírus Humano (HPV) afeta a qualidade vida de mulheres infectadas no aspecto social, sexual, mental e físico. Métodos: Trata-se de uma abordagem qualitativa, realizada por meio de uma revisão integrativa de literatura. Uma busca por trabalhos prévios foi realizada nas plataformas National Library of Medicine, Biblioteca Virtual de Saúde e Cochrane Library utilizando os descritores “hpv-infection”, “mental health” e “consequences”. Foram incluídos no estudo artigos em inglês, português e espanhol, publicados no período de 2017 a 2022 que não fugiam ao tema proposto. Resultados: Foi observado que, poucas mulheres possuíam informações prévias sobre o HPV, levando a sintomas como ansiedade, depressão, estresse, dúvidas sobre fertilidade, contaminação, transmissão, fidelidade de seu parceiro, métodos contraceptivos, falta de comunicação no seu relacionamento e medo do câncer. Muitas pacientes demonstraram a necessidade do fornecimento de apoio e informações pelo seu médico. Considerações finais: Educação sexual se faz imprescindível para conscientização da população, a fim de evitar o estigma relacionado a Infecções Sexualmente Transmissíveis, ansiedade desnecessária e redução da contaminação e transmissão da doença.

Objetivo: Analisar através de uma revisão narrativa sobre as condutas clínicas da Otite Média Aguda (OMA) nas crianças. Revisão bibliográfica:  A infância é caracterizada por Otite Média (OM), que é definida por infecção da orelha média que acomete principalmente a fase pré-escolar. Essa patologia se sub categoriza em: OMA, Otite Média aguda recorrente, Otite Média com efusão e Otite Média Crônica (OMC). A sintomatologia da OMA é marcada por febre, irritabilidade, otorreia, anorexia e vômitos. Anatomicamente, a criança apresenta a tuba auditiva mais horizontalizado que nos adultos, o que corrobora para o desenvolvimento da OMA. A doença costuma ser precedida por infecção viral do trato respiratório superior e provoca edema da tuba auditiva. A complicação mais comum da OMA é a mastoidite aguda que favorece o acúmulo de secreção purulenta e a colonização bacteriana, que obtém melhora com antibiótico. Considerações finais: A otite média é uma doença que atinge crianças de 2-6 anos juntamente com a sintomatologia característica. O diagnóstico se assemelha entre OME e OMC que dificulta um desfecho. A resolução pode ser espontânea em sua maioria com uso de sintomáticos. O antibiótico é reservado para a prevenção de possíveis complicações.

Published: August 2022

Objetivo: Revisar na literatura científica o mecanismo de ação da ozonioterapia no manejo da dor e reunir situações em que seu uso é benéfico. Revisão bibliográfica: O ozônio em forma medicinal é uma mistura entre 95-99% de gás oxigênio e 1-5% de ozônio. Essa terapia é utilizada em numerosas condições marcadas por processos inflamatórios crônicos e hiperativação imunológica. A terapia age produzindo um processo oxidativo moderado por interações entre os componentes biológicos e o 03, resultando em produtos como o peróxido de hidrogênio (H2O2), uma espécie reativa fundamental do oxigênio (ROS). As contraindicações do métodos e seus efeitos colaterais precisam ser conhecidos, mas devem ser mais testados in vivo. Estudos evidenciam o uso benéfico da ozonioterapia em: fibromialgia, hernia de disco, osteoartrite, artrite reumatoide, dores devido ao tratamento de câncer, neuralgia pós herpética, fascite plantar e cicatrização de feridas. Considerações finais: A ozonioterapia proporciona aos pacientes uma opção de tratamento de baixo custo, muito eficaz e que traz menos agressão ao corpo, não deixando resíduos químicos. É uma terapêutica cujo estudo e conhecimento por profissionais é de extrema importância, por ser uma opção que devolve grande parte da qualidade de vida perdida aos pacientes que convivem com a dor.

The characteristic curvature (Cc) definition and its use in assessing Cc for single ionic surfactants
Authors: Leng Zhuotao , Acosta Edgar
Published: August 2022

The Hydrophilic-Lipophilic-Difference (HLD) is a set of empirical equations that correlate the formulation conditions at phase inversion (HLD=0). Based on partition studies for nonionic surfactants, the HLD can be interpreted as a normalized chemical potential difference between the surfactant dissolved in water and oil. The Net-Average Curvature (NAC) model extrapolates this interpretation into a curvature form that has been used to fit and predict the phase behavior of surfactant-oil-water (SOW) systems. The curvature interpretation of HLD led to the renaming of the HLD surfactant parameter, sigma (σ), as the characteristic curvature (Cc). This work addresses two concerns around this interpretation; first, for ionic surfactants, an HLD≠0 value for one surfactant might not mean the same for another (breaking the chemical potential interpretation), and second, the Cc interpretation has not been demonstrated. To this end, the net curvature (Hn) of six anionic and two cationic surfactants was evaluated (individually) from solubilization data at the characteristic condition of 25°C, no added cosolvent, in the presence of an oil mixture with equivalent alkane carbon number (EACN) of zero, and as a function of salinity. These studies showed that, indeed, the original HLD equation for ionic surfactant could not be interpreted as chemical potential or curvature because a salinity prefactor "bi" was missing. The revised equation, HLDbi = bi∙ln(S)-kbi∙EACN+Ccbi -aTbi∙(T-25°C), could now be interpreted as a curvature expression, and it was demonstrated that Cc could be obtained from curvature at characteristic conditions, only that the proper expression is Cc = Ccbi/bi.

Published: August 2022

The practical and facile difluorocarbene-triggered cycloaddition reaction of enaminones was developed, that delivered 2,2-difluoro-2,3-dihydrofurans with broad substrates scope. Notably, the reaction proceeded smoothly without any extra additive. The readily available sodium chlorodifluoroacetate (ClCF2CO2Na, SCDA) played as difluorocarbene precursor in this transformation through DMF-promotion. Moreover, it is proved that the 2,2-difluoro- 2,3-dihydrofuran derivatives exposed potential antiproliferative activity against human tumour cells HeLa, MCF7 and HepG2.

Degradation Mechanisms of the Detector Properties of CdTe and CdZnTe Under the Influence of Gamma Irradiation
Authors: Kondrik Alexandr I.
Published: August 2022

This work is devoted to the study of the mechanisms of the influence of radiation defects, arising under the influence of gamma irradiation, on the change in resistivity ρ, lifetime of nonequilibrium electrons τn and holes τp, in CdTe:Cl and Cd0.9Zn0.1Te as well as the collection efficiency η of uncooled radiation detectors based on these materials, by computer simulation method. Radiation defects, that are corresponded by deep energy levels in the band gap, act as trapping centers of nonequilibrium charge carriers, noticeably affect the degree of compensation by changing ρ of the detector material, the recombination processes by decreasing τn and τp, what ultimately can cause degradation of the charges collection efficiency η. The specific reasons for the deterioration of the detector properties of CdTe:Cl and Cd0.9Zn0.1Te under the influence of gamma irradiation were identified, and the main factors leading to complete degradation of the recording ability of detectors based on these semiconductors during their bombardment by 60Co gamma quanta were determined. The gradual degradation of the spectroscopic performance of CdTe:Cl-based detectors during gamma irradiation occurs due to the continuous formation of cadmium vacancies VCd and acceptor complexes VCd – Cl, which continuously shift Fermi level towards valence band and decrease ρ. The complete performance degradation of CdTe detectors takes place mainly due to the capture of nonequilibrium electrons at energy level of interstitial tellurium Te(I). The invariable spectroscopic properties of CdZnTe-based sensors under gamma irradiation up to 25 kGy occur due to the mechanism of radiative self-compensation by formation of substitutional defect TeZn. At the final stage of irradiation, a sharp deterioration in the detector properties of CdZnTe occurs, mainly due to the capture and recombination of nonequilibrium charge carriers at the level of the Te(I) defect. The different radiation resistances of CdZnTe and CdTe:Cl can be explained by different behavior of Fermi level EF in these semiconductors under gamma irradiation. EF in CdZnTe under radiation exposure remains near the middle of band gap, and in CdTe it drifts to the valence band. The rate of capture and recombination through Te(I) donor level in CdTe:Cl is lower than in CdZnTe due to the larger difference between the Fermi level and the radiation defect Te(I) level in cadmium telluride. Thereby, the complete degradation of the CdTe:Cl detector occurs at a higher concentration of radiation defect Te(I), and hence after a higher irradiation dose of 50 kGy compared with a dose of 30 kGy required for degradation of CdZnTe detector properties.

Nanostructured coatings based on amorphous carbon and carbon-doped with gold, silver, and nitrogen were obtained by the pulsed vacuum-arc method. Carbon coatings have been annealed in a vacuum as well as treated with argon ions. The alloying of carbon coatings with elements that do not form chemical bonds with the carbon matrix (Ag, Au) leads to the formation of gold or silver nanocrystallites with sizes of 2 ‑ 20 nm in the matrix of amorphous carbon, whose density depends on the concentration of the doping element. Annealing of silver-doped carbon coatings leads to the formation of islands on the surface with the size of the order of micrometers. This is due to the silver diffusion and coalescence of small islands into larger ones. The HRTEM method discovered the effect of twinning in carbon nanocrystallites after vacuum annealing as well as silver and gold in the initial state (the formation of single-crystal regions with an altered orientation of the crystal structure) in the amorphous carbon matrix. Analysis of Raman spectra of pure carbon coating and silver-doped showed that the addition of silver leads to a decrease in sp3-phase in the carbon matrix. This effect is particularly evident in the nature of changes in the spectra after vacuum annealing at 600 ºC. The addition of nitrogen in the carbon coating leads to an increase in the sp2 ‑ phase fraction, and additional annealing leads to a significant increase in the D - peak intensity and formation of clusters of the order of 5 ‑ 15 nm, which are not localized but fill the entire space. Analysis of the coating a-C: Au irradiation with argon ions shows that the number of nanopitches decreased after ion irradiation, simultaneously decreased surface roughness degree, besides, decreased electrical conductivity of the coating as a result of decreased gold content. It was found that the conditions of nanostructured coatings and their subsequent processing allow controlling the properties of nanocoatings (structure, size of nanoparticles, surface topography, and electrical conductivity).

The paper presents the results of the study of properties of fast surface electromagnetic waves that propagate along the flat interface between the active metamaterial and air (or vacuum). The case of homogeneous and isotropic metamaterial is considered. The dispersion properties, the wave spatial attenuation, the phase and group velocities, as well as the spatial distribution of the electromagnetic field of the eigen TE and TM modes of such a waveguide structure are studied in the frequency range where the metamaterial has a simultaneously negative permittivity and permeability. It is shown that fast surface electromagnetic waves can exist in this waveguide structure and their properties are studied. It is shown that the phase speed of TM mode is several times higher than the speed of light in vacuum, while the phase speed of TE mode is slightly higher than the speed of light in vacuum. The TM mode is a direct wave in which the phase and group velocities have the same direction. It is obtained that the group velocity of the TM mode varies from zero to the about half of speed of light in vacuum, and reaches a minimum at a certain value of wave frequency, which depends on the characteristics of the metamaterial. It is shown that the penetration depth of the TM mode into the metamaterial is much smaller than into the vacuum. The TE mode is a backward wave with opposite directed phase and group velocities. The absolute value of the group velocity of the TE mode is about six times less than the speed of light in vacuum. In contrast to the TM mode the penetration depth of the TE mode into the metamaterial is much greater than in vacuum. The obtained properties of the fast surface electromagnetic waves can be used for modeling and design of modern generation and amplification devices containing metamaterials.

Objective: The link between snus, periodontal diseases and oral malignancy is still in question in different literature. This study aims to explore the impact of snus on mucosal lesions and oral malignancy along with evaluation of strategies for snus cessation and approaches to communication with patients. Methods: A questionnaire about tobacco consumption habits was made. A heavy snus group, a light snus group and a control group were made. Oral biopsy samples were tested for protein gene product 9.5, tissue inhibitor of matrix metalloproteinase 2, chromogranin A and B, matrix metalloproteinase 2, interleukin-1, interleukin-10 using immunohistochemical techniques. Periodontal pocket biofilms were tested with combined polymerase chain reaction and were subsequently analyzed in order to determine the presence of pathogenic periodontal bacteria, such as Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola and Prevotella intermedia. Results: Biopsy results showed cellular disorganization, apoptosis, hyperkeratosis and prevalence of keratotic seborrhea in the area of snus sachets. Microbiological examination revealed the presence of periodontal pathogens in the snus users group. High concentration of pathogenic periodontal bacteria Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis and Prevotella intermedia was found in groups of both heavy and light snus users, yet they were absent in the samples of the control group. High concentration of Tannerella forsythia and Treponema denticola was also found in the groups of heavy and light snus users, whereas they were present in samples of only two patients of the control group. Conclusions: Snus changes cell function, it can lead to oral malignancy and promote periodontal disease regardless of the frequency and amount of snus used.

Introduction. Currently, the coronavirus pandemic remains high on the world community, and it is discussed on a daily basis, posing a serious threat. Despite the fact, that most people recover from coronavirus infection, many suffer from the manifestations of the post-COVID syndrome that became a significant social problem due to disruption the normal lifestyle and daily functioning, reduced quality of life. The fact, that the development of the mechanism of post-COVID conditions has not been studied much is a challenge for medical community, so its efforts should be aimed at the analysis of these mechanisms. Objective: to assess the prevalence of post-COVID symptoms among residents of Kharkiv and to provide recommendations regarding the management of such patients. Materials and methods. The study involved 60 respondents, including 43 females and 17 males, all participants were older than 20 years. Using a self-designed questionnaire applying in Google Docs, the incidence of symptoms due to post-COVID syndrome was assessed among all respondents, as well as separately among males and females, and depending on the time since the disease, whether physical activity remained at the same level, and, also whether such patients seek medical help. Results. The study has shown the primary role of tiredness and fatigue, it was noted by 37 respondents (61.7 %), difficulty thinking and concentrating (so-called «foggy brain») – 35 participants (58.3 %), decrease the exercise tolerance – 34 respondents (56.7 %), muscle pain – 27 respondents (45 %), sleep disorders and joint pain at the same level – 26 respondents (43.3 %). The gender-specific was analyzed, so there were some differences. It was found that physical activity in 35 respondents (58.3 %) was decreased that leads to hypodynamy resulting in a reduced quality of life. Conclusion. Bearing this in mind, the authors consider it necessary to create a comprehensive rehabilitation plan with the participation of a physical therapist and other professionals, using the recommendations of reputable institutions such as the National Institute for Health and Care Excellence (NICE) and the Centers for Disease Control and Prevention (CDC).
Aportes del nuevo marco para las funciones esenciales de salud pública a la lucha contra la pandemia de COVID-19

En el presente artículo se utiliza una perspectiva de rectoría de la salud, con el fin de interpretar las fortalezas y los obstáculos relativos a las capacidades de las autoridades nacionales de salud para responder ante la pandemia de COVID-19, a través del marco renovado de las funciones esenciales de salud pública (FESP). Sobre la base de una revisión bibliográfica, se sostiene que las capacidades institucionales que necesitan los países de la Región de las Américas para responder ante la pandemia de COVID-19 incluyen las cuatro etapas del nuevo ciclo de políticas en las FESP: la evaluación, la formulación de políticas, la asignación de recursos y el acceso. Aunque las autoridades de salud proporcionaron las funciones esenciales (por ejemplo, análisis de datos, diálogos intersectoriales en materia de políticas y asignación de fondos adicionales), las intervenciones que se implementaron estuvieron sujetas a las estructuras institucionales de cada país. Las autoridades de salud tuvieron que hacer frente a desafíos considerables como la fragmentación y la falta de capacidades institucionales y de personal, lo que pone en peligro la ejecución de actividades de respuesta eficaces y equitativas. Además, la respuesta a la pandemia ha sido desigual debido a algunas debilidades en la capacidad central de liderazgo y coordinación, la politización de las actividades de respuesta y las diferencias en la capacidad de respuesta a nivel subnacional. Esos desafíos son el reflejo de deficiencias estructurales que ya existían antes de que comenzara la pandemia, así como de la asignación de una prioridad baja a la salud pública en la agenda para el fortalecimiento de los sistemas de salud. En las agendas que se elaboren en el futuro debe darse prioridad a mejorar los elementos estructurales, fortalecer las capacidades de rectoría de las autoridades de salud y crear estructuras institucionales que garanticen tanto el acceso universal a la atención de salud como la cobertura universal de salud.
