Authors: Chumachenko I. , Davidich N. , Galkin A. , Davidich Yu. , Kush Y. , Samchuk G.
Published: July 2021

The article is devoted to the establishment of information support to determine the patterns of changing the function of gravitation of employees of the urban-service enterprises. It has been established that the development of urban transport systems is impossible without the use of information technology to predict the parameters of the formation and absorption of passenger traffic. The design of urban transport systems cannot be achieved without assessing the impact of traffic improvement measures on changes in traffic and passenger flows. The main parameter by which it is possible to predict the choice of places of gravity by the inhabitants of cities is the function of gravitation between different areas of the city. The formalized functions of the gravitation of urban dwellers are not differentiated by the social composition of the population of cities. In addition, they use only travel time between areas of the city as an independent variable. The article proposes the formalization of the gravitation function of employees of the urban service enterprises using the parameters of the urban transport system, areas of departure and arrival, as well as the cost of movement. A special questionnaire has been developed to obtain the original information. A natural survey was carried out using it. As a result of the processing of survey data using correlation and regression analysis methods, the degree of influence of the studied factors on the value of the gravitation function of employees of urban service enterprises was revealed. Analysis of the correlation values obtained showed that the most significant impact on the value of the gravitation function of employees of urban services is the ratio of the cost of movement between districts and average wages in the city. The least impact is the distance from the area of residence to the place of application of work, the ratio of the cost of one square meter of housing in the area of residence and the average salary in the city, the ratio of the cost of one square meter of housing in the area of employment application and the average salary in the city. However, the compatible influence of all factors can change the level of influence of each factor and its combinations. In addition, it is advisable to take into account the technical and operational performance of urban passenger transport routes and individual transport routes.

Published: July 2021

This paper presents an innovative method of reinforcement of concrete based on the use of the Jute fibers composites. These renewable raw bioresource fibers are available at a low cost. Moreover, they can be compared to Glass Fiber-Reinforced Polymer (GFRP) by enhancing the resistance of Jute Fiber-Reinforced Polymer (JFRP), while improving the compatibility between the fiber and the resin. For that purpose, this paper presents an experimental study that evaluates the influence of the curing conditions (time and temperature) on the behavior of JFRP laminates and concrete members strengthened by JFRP. The curing conditions at 30 °C for 2h 30min and at 50 °C for 1 h were the only two parameters studied and determined on the basis of Sikadur 330 properties and preliminary tests. Through the experimental tests, the maximum load capacity and observed failure modes are investigated. The results indicated that the curing at 30 °C for 2h 30min is the optimum curing condition. In addition, a low difference in the maximum load capacity was noted in the case of 50 °C. As to the failure modes, all the specimens cured with additional heat before being left under room conditions, have shown the ductile mode failure, especially in the case of specimens cured at 30 °C during 2h 30min. The analytical model conducted in this paper predicts the elastic modulus depending on temperature. The obtained results and proposed model can be used as input parameters in the analysis and design of externally strengthened members with Jute FRP composites.
Size/Layout Optimization of Truss Structures Using Vibrating Particles System Meta-heuristic Algorithm and its Improved Version
Authors: Kaveh Ali , Khosravian Masoud
Published: July 2021

Vibrating Particles System (VPS) optimization is a newly made meta-heuristic algorithm to optimize problems by inspiration of the free vibration of viscous-damped systems with single degree of freedom. The agents are modeled as particles which systematically proceed toward their equilibrium conditions that are reached by the existing population and historically best position. To enhance the performance of the VPS algorithm, Enhanced Vibrating Particles System (EVPS) applies a new process for updating agent’s positions. This paper tries to improve the EVPS algorithm with the aim of reduction in the regulatory parameters’ effect on the algorithm's performance by reducing the regulatory parameters. To evaluate the performance of the proposed method, it is applied to four optimization problems of truss structures including mixed of discrete and continuous design search spaces with displacement, stress and buckling constraints. As a result, the proposed algorithm is a suitable method and more research can be done on it.

Authors: Bittencourt Vivian Lemes Lobo , Schwengber Maria Simone Vione , Stumm Eniva Miladi Fernandes
Published: July 2021

Esse artigo objetiva mapear estudos sobre ações educativas acerca da segurança do paciente no perioperatório, no decorrer da hospitalização. Trata-se de uma revisão narrativa a partir do mapeamento das produções de enfermeiros, em teses e dissertações brasileiras. Foram desenvolvidas cinco buscas no dia 15 de dezembro de 2020 no Catálogo de Teses e Dissertações da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior, com combinações variadas dos descritores e/ou palavras-chave: paciente, cirúrgico, educação de pacientes como assunto, educação em saúde, segurança do paciente, enfermagem, enfermagem perioperatória, período pré-operatório, período pós-operatório, hospital. O operador booleano “AND” foi utilizado para interligar os termos nas buscas. Nove produções foram selecionadas e analisadas. Identificou-se várias percepções positivas de pacientes referentes a ações educativas desenvolvidas, valorização de informações sobre a hospitalização, cirurgias e qualidade dos variados temas abordados para a segurança dos pacientes. A pesquisa possibilitou conhecer estudos que tematizam ações educativas acerca da segurança dos pacientes no perioperatório desenvolvidas na hospitalização, porém não deixam claro se os pacientes relacionam as ações educativas em saúde com a segurança. A análise dos estudos que integraram essa revisão demonstra a lacuna de investigações que contemplem ações educativas por enfermeiros direcionadas à segurança do paciente cirúrgico.

Authors: Sant'Ana Leandro , Bara-Filho Maurício Gáttas , Vianna Jeferson Macedo
Published: July 2021

Na corrida, a demanda de ajustes para otimizar os estímulos para a obtenção de melhor desempenho é algo relevante e indispensável. Com isso, a prescrição para o treinamento de corrida, seja esta curta, média e longa distância, deve ser estritamente adequada, assim como todo o processo recuperativo, permitindo assim, melhores adaptações fisiológicas. Para isso, o controle da carga de treinamento é algo imprescindível e além disso, a possibilidade de obter respostas positivas torna-se maior, visto que o indivíduo estará mais preservado de possíveis estresses decorrentes do acúmulo de fadiga. O controle da carga de treinamento é uma ótima ferramenta para treinadores identificar o momento de continuar na aplicação de estímulos, bem como no controle destes perante aos atletas. Com isso, é possível evitar sobrecargas excessivas que podem expor o atleta a um decréscimo do desempenho e até mesmo de uma lesão e, na corrida esta intervenção é de extrema importância. Dentre os tipos de avaliações utilizadas, a utilização do cálculo da percepção subjetiva do esforço da sessão (PSE), a frequência cardíaca (FC), a variabilidade da frequência cardíaca (VFC) e marcadores bioquímicos (lactato, creatinaquinase e cortisol salivar) são os mais comuns dentre as mensurações da carga de treinamento (ou carga interna). A presente revisão, teve por objetivo, descrever a eficiência destes métodos e respostas que possibilitam a avaliação da carga de treinamento na modalidade da corrida. Diversos estudos demonstraram, através de diferentes ferramentas para tal tipo de análises, a eficiência e sobretudo a importância do procedimento de análise e avaliação da carga de treinamento. Procedimentos indiretos, com por exemplo a PSE e VFC, foram correlacionados por diferentes estudos, com outros indicadores internos de intensidade do exercício, como, por exemplo, o consumo de oxigênio, a frequência cardíaca e a concentração de lactato. No entanto, é necessário a elaboração de mais estudos investigando a carga de treinamento em atletas/praticantes de corridas, para assim, ter maiores informações sobre esta ferramenta de extrema importância para esta modalidade.

Authors: Fernandes Roberto Mauro da Silva
Published: July 2021

O Programa de Investimento em Logística (PIL) foi lançado durante a primeira gestão (2011-2014) da Presidenta Dilma Rousseff. O PIL tinha como objetivo promover inovação logística para o Brasil. Entretanto, um conjunto de relações de força do Estado, ocorridas entre os anos de 2013 e 2016, influenciou e alterou o que estava originariamente previsto, neste contexto foi criado um novo marco regulatório para o setor portuário brasileiro. Desta maneira, o objetivo deste artigo é descrever as estratégias, as diretrizes e objetivos do “PIL: portos” analisando aspectos importantes da Lei n. 12.815/13 (o marco regulatório para o setor portuário brasileiro), bem como, vamos verificar as contradições de classe envolvidas no processo. Para tal, fizemos uso de levantamento bibliográfico, documental e no ciberespaço.

Published: July 2021

Objective: This study evaluated the bacterial removal in flattened root canals after preparation with different tapers of ProDesign Logic instruments. Methodology: Fifty-five mandibular incisors with flattened root canals were contaminated with a pure culture of Enterococcus faecalis ATCC 29212 for 21 days at 37ºC. Root canals preparation was performed using ProDesign Logic and 0.9% sterile saline solution for irrigation. The specimens were randomly allocated to three experimental groups (n = 15) according to the taper of the instrument used: 25.03, 25.04, or 25.06. Intracanal bacteriological samples were taken before (S1) and after (S2) preparation and the number of colony-forming units per milliliter (CFU/mL) was calculated. Differences in bacterial counts before and after treatment, within each group, were analyzed by the paired t-test. Groups were compared by ANOVA with a post hoc test. The level of significance was set at p <0.05. Results: Mature biofilm formation was confirmed at root canal walls by scanning electron microscopy. Bacterial colonies were significantly reduced in all experimental groups at S2 compared to S1 (p <0.001). No significant difference was observed between groups regarding the percentage of bacterial reduction (p >0.05). Conclusion: Preparation of flattened root canals using ProDesign Logic instruments with tapers of 0.03, 0.04 and 0.06 resulted in similar planktonic and bacterial biofilm reduction. None of the instruments rendered root canals completely free of bacteria.

Os Bifosfonatos são fármacos que atuam diminuindo e inibindo a atividade osteoclástica, e induzindo a apoptose celular. Bloqueiam a diferenciação dos osteoclastos e estimulam os osteoblastos, acarretando a diminuição da reabsorção óssea. Podendo contribuir para exposição de osso necrótico na região bucomaxilofacial. Desta forma, a presente revisão narrativa propõe uma breve discussão, acerca do desenvolvimento da osteonecrose dos ossos maxilares decorrentes da terapia com bifosfonatos. Tendo como temática o desenvolvimento da osteonecrose nos maxilares decorrentes do uso dos bifosfonatos, buscou-se através dos MeSH terms e DeCS/MeSH terms, entre 2006 e 2021, artigos no idioma inglês e português indexados na base de dados do MEDLINE/PubMed, Web of Science, LILACS/bvs bem como, através de uma busca manual. Após a análise dos artigos selecionados observou-se que a possibilidade do desenvolvimento da osteonecrose nos ossos maxilares é multifatorial, sendo desta forma imperativo uma abordagem, a estes sítios, de cunho preventivo e com uma terapêutica minimamente invasiva.

Authors: Galdino Luana Laureano , Brito Arella Cristina Muniz
Published: July 2021

A busca pela excelência estética é uma das metas da odontologia, pois faz parte da estética do sorriso, pois interfere diretamente na autoestima e na qualidade de vida do paciente. Conceitualmente, o sorriso gengival é a exposição excessiva de gengiva ao sorrir, podendo ser considerada a partir de 2mm. Uma das opções de correção é com o uso da toxina botulínica. Em vista disso, o objetivo do presente estudo foi realizar uma revisão da literatura sobre os estudos científicos atuais acerca da correção do sorriso gengival com a toxina botulínica tipo A. Para tanto, realizou-se uma busca dos principais artigos publicados nos últimos 5 anos nas bases de dados: PubMed, SciELO, LILACS e BVS utilizando como descritores inglês “smile”, “gummy smile”, “gingiva” e “Botulinum ToxinsType A”. Baseado no resultado da busca dos 22 artigos encontrados, o tratamento do sorriso gengival com toxina botulínica tipo A atua sobre a hiperatividade dos músculos envolvidos no sorriso causando um relaxamento temporário, podendo ser uma técnica independente ou coadjuvante de outros procedimentos. Apresentando eficácia, resultados positivos estéticos e baixo índice de complicações. No entanto, a principal desvantagem consiste no efeito temporário, com duração média de 4 a 6 meses, necessitando de reaplicações com o passar do tempo. Diante desse contexto, pode-se concluir que o uso desta toxina para a redução do sorriso gengival é uma opção de procedimento seguro, rápido, eficaz e conservador. Entretanto, ensaios clínicos randomizados bem delineados são necessários para fortalecer as evidências.

SARS-CoV-2 is an RNA virus, responsible for causing an acute respiratory syndrome, which became known worldwide for its rapid spread and for causing the pandemic of a new disease: COVID-19. Thus, epidemiological studies have been developed in order to determine the extent of the problems and the magnitude of the disease. The present study aimed to evaluate the seroprevalence of SARS-CoV-2 infection and its relationship with socio-demographic and clinical-epidemiological factors in the city of Chapecó, Santa Catarina, Brazil. It was a quantitative, epidemiological, observational, cross-sectional, population-based study with 2179 participants. Socio-demographic, associated behavioral, aggravating and comorbid parameters were evaluated, relating them to positivity or not in the rapid test implemented. The rapid test identified 22.2% of the diagnosed seroprevalence of COVID-19 in the municipality in question. A higher incidence of cases was observed in people living with other people, in people who had contact with positive cases, and in symptomatic patients, corroborating with current studies. The results highlight the importance of clinical-epidemiological studies for the understanding and control of COVID-19.

Bromazepam emulates the inhibitory effect of the neurotransmitter gamma-aminobutyric acid (GABA) and can lead to impaired visuomotor performance. However, few studies have evaluated its effects on cortical coupling in target shooting activities. The present study aimed to analyze the acute effects of bromazepam administration in a target shooting task and the EEG theta rhythm coherence between frontal, temporal, and motor cortical areas in four shooting preparation periods. Thus, a double blind, crossover study was conducted with 30 subjects under two conditions: bromazepam (6mg) and placebo, with electroencephalographic analysis to simultaneously study the theta rhythm coherence in frontal, temporal, and motor cortex in a target shooting task; and the possible interferences of bromazepam administration. Subjects in the bromazepam group showed lower performance on the task compared to placebo (p=0.001). In addition, our analysis showed decreased coherence between regions in the same hemisphere, increased theta rhythm coherence in interhemispheric regions in frontal, temporal and motor cortex at different intervals in the preparation preceding the shooting (p=0.001). The use of bromazepam may influence task execution, possibly due to neurochemical modulation, during decision making, developing shooting preparation strategies, as well as interfering with the flow of information at the level of attention during task execution.

O presente artigo tem o objetivo de analisar o processo de formação profissional relacionado à docência em centros e escolas de beleza. Para alcançar esse objetivo, foi desenvolvida uma pesquisa de natureza qualitativa que consistiu, inicialmente, na abordagem de conceitos como beleza e estética atinentes ao campo profissional. Além disso, a formação do profissional foi abordada nos distintos níveis de ensino, a saber: básico e superior. Para isso, a pesquisa bibliográfica exploratória foi fundamental para dar subsídios na elaboração do quadro teórico deste trabalho. Partiu-se da hipótese de que para uma formação sólida na área da beleza é preciso alinhar o posicionamento de ensino referente ao grau técnico utilizado ou direcionado sobre a identificação do potencial de cada indivíduo, respeitando seu posicionamento, experiências, vivências, particularidades e aplicabilidade de técnicas referentes aos serviços prestados. Por fim, também foi apresentado, sob orientação etnográfica, a partir de vivência formativa de um dos signatários desta pesquisa como aluno e como instrutor na área da beleza, relatos autobiográficos para corroborar a necessidade de uma formação continuada e subsidiar uma proposta formativa. Como resultados parciais, é possível indicar uma formação profissional continuada, com oportunidade de atuação docente. Ao final deste trabalho, foi possível constatar a necessidade de formação continuada do profissional docente na área da beleza como diferencial competitivo no mercado, mas que não se limite a isso, ao contrário, transcenda e alcance uma educação crítica e transformadora.

To analyze the labeling adequacy of Greek Yogurts with the current Brazilian legislation for packaged products, which includes the list of ingredients, the content of proteins, carbohydrates and sugars, the amount of saturated fat and the presence of additives. This research was done in products of this kind available in João Pessoa - Paraíba supermarkets. The data collected was about the list of ingredients, nutritional facts and the information contained on the labels. The collected data were tabulated on the Excel ® spreadsheet and analyzed statistically by Principal Component Analysis (PCA). 107 yogurts from 10 different brands were evaluated, in which all yogurts were in compliance with current legislation. As of nutritional composition, the products had high amounts of added sugars, saturated fat and additives, which differs from the original composition of the original Greek yogurt recipe; however, the G brand had the lowest content of added substances and the best nutritional quality. The results show that consumers need to pay attention to product labels to make better choices, nutrition professionals are expected to better understand the composition of these yogurts to effectively guide their consumption.
Application of Modified Mesenchymal Stem Cells Transplantation in the Treatment of Liver Injury
Authors: LIU L , YANG F
Published: July 2021

Acute and chronic hepatitis, cirrhosis, and other liver diseases pose a serious threat to human health; however, liver transplantation is the only reliable treatment for the terminal stage of liver diseases. Previous researchers have shown that mesenchymal stem cells (MSCs) are characterized by differentiation and paracrine effects, as well as anti-oxidative stress and immune regulation functions. When MSCs are transplanted into animals, they migrate to the injured liver tissue along with the circulation, to protect the liver and alleviate the injury through the paracrine, immune regulation and other characteristics, making mesenchymal stem cell transplantation a promising alternative therapy for liver diseases. Although the efficacy of MSCs transplantation has been confirmed in various animal models of liver injury, many researchers have also proposed various pretreatment methods to improve the efficacy of mesenchymal stem cell transplantation, but there is still lack a set of scientific methods system aimed at improving the efficacy of transplantation therapy in scientific research and clinical practice. In this review, we summarize the possible mechanisms of MSCs therapy and compare the existing methods of MSCs modification corresponding to the treatment mechanism, hoping to provide as a reference to help future researchers explore a safe and simple transplantation strategy.
The Abnormalities of Adrenomedullary Hormonal System in Genetic Hypertension: Their Contribution to Altered Regulation of Blood Pressure
Authors: Vavřínová A
Published: July 2021

It is widely accepted that sympathetic nervous system plays a crucial role in the development of hypertension. On the other hand, the role of adrenal medulla (the adrenomedullary component of the sympathoadrenal system) in the development and maintenance of high blood pressure in man as well as in experimental models of hypertension is still controversial. Spontaneously hypertensive rats (SHR) are the most widely used animal model of human essential hypertension characterized by sympathetic hyperactivity. However, the persistence of moderately elevated blood pressure in SHR subjected to sympathectomy neonatally as well as the resistance of adult SHR to the treatment by sympatholytic drugs suggests that other factors (including enhanced activity of the adrenomedullary hormonal system) are involved in the pathogenesis of hypertension of SHR. This review describes abnormalities in adrenomedullary hormonal system of SHR rats starting with the hyperactivity of brain centers regulating sympathetic outflow, through the exaggerated activation of sympathoadrenal preganglionic neurons, to the local changes in chromaffin cells of adrenal medulla. All the above alterations might contribute to the enhanced release of epinephrine and/or norepinephrine from adrenal medulla. Special attention is paid to the alterations in the expression of genes involved in catecholamine biosynthesis, storage, release, reuptake, degradation and adrenergic receptors in chromaffin cells of SHR. The contribution of the adrenomedullary hormonal system to the development and maintenance of hypertension as well as its importance during stressful conditions is also discussed.
Normative Political Science – How to Measure the Goodness of a Political System
Authors: Kelleher William
Published: July 2021

As is well known, David Easton defines the political system as emerging from those social interactions undertaken in relation to the authoritative allocation of values for a society. This paper explains two normative services that Easton’s definition can provide for political science; one is explanatory, the other evaluative. The explanatory service is to show both the distinctiveness of political science as a social science and to serve as a standard, or norm, by which to set the boundaries of the profession’s subject matter. Secondly, Easton’s theory of the political system as an input/output model can serve as a standard by which to assess the “goodness” of a political system, and for comparing the goodness of systems. Assessing such goodness is not a matter of moral approval or approbation, but more like the taxonomist assessing the goodness of a specimen, as to both its categorical fit and its health.

Published: July 2021

This article aims to analyze Indonesia’s decision on World Health Organization Framework Convention on Tobacco Control (WHO FCTC) in the leadership period of President Joko Widodo from 2014-2019. As one out of nine states which have not to sign and ratify WHO FCTC, historically Indonesia is one of the full drafting member states which actively involved in the convention’s making and negotiations since 1996. However, from 2003 until 2019, Indonesia still refuses to sign or ratify WHO FCTC. From past years, studies about Indonesia’s non-compliance decision on WHO FCTC limited by the analysis focused on domestic factors to explain state’s behavior, non-state actors’ interest, or discourse about tobacco control issues.

The aim of the current study is to investigate the properties of graphene nanoplatelets-cementitious composites in a consistent sense. The influence of the addition of 2D graphene nanoplatelets (GNPs) on the workability, setting time, flowability, strengths and piezoresistive properties were studied. The dosage of the GNPs is 0 0.05, 0.1, 0.3, 0.5, 0.7, and 1.0 wt% of the binder material. PVP type surfactant was used to disperse GNPs. The experimental results showed that the addition of GNPs increases the water requirement for normal consistency and decreases the flowability. A small amount of GNPs (0.05 wt%) can facilitate the setting. When the dosage of GNPs is above 0.1 wt%, it leads to the delay of the setting time. In terms of the strengths, the addition of GNPs can considerably promote the flexural strength, while the compressive strength is slightly decreased until 28 days. A pre-treatment procedure consisting of drying specimens at 105°C for 1 day can be regarded as a proper way to enhance the piezoresistive properties of the GNPs-mortar. Piezoresistive properties under two different cyclical loading schemes were measured using the GNPs-mortar with 1 wt% GNPs. It has been shown that the average resistance change rate increases with the amplitude increasing and a reduction is observed for the sustained cyclical loading condition. In the end, the influence of the microcracks on the piezoresistive properties was investigated. This study will contribute to future developments of cementitious composites incorporating GNPs for a variety of applications.

Hypoxia is one of the most common pathological conditions, which can be induced by multiple events, including ischemic injury, trauma, inflammation, tumors, etc. The body’s adaptation to hypoxia is a highly important phenomenon in both health and disease. Most cellular responses to hypoxia are associated with a family of transcription factors called hypoxia-inducible factors (HIFs), which induce the expression of a wide range of genes that help cells adapt to a hypoxic environment. Basic mechanisms of adaptation to hypoxia, and particularly HIF functions, have being extensively studied over recent decades, leading to the 2019 Nobel Prize in Physiology or Medicine. Based on their pivotal physiological importance, HIFs are attracting increasing attention as a new potential target for treating a large number of hypoxia-associated diseases. Most of the experimental work related to HIFs has focused on roles in the liver and kidney. However, increasing evidence clearly demonstrates that HIF-based responses represent an universal adaptation mechanism in all tissue types, including the central nervous system (CNS). In the CNS, HIFs are critically involved in the regulation of neurogenesis, nerve cell differentiation, and neuronal apoptosis. In this mini-review, we provide an overview of the complex role of HIF-1 in the adaptation of neurons and glia cells to hypoxia, with a focus on its potential involvement into various neuronal pathologies and on its possible role as a novel therapeutic target.

Published: July 2021

A porous semi-interpenetrating network (semi-IPN) hydrogel adsorbent with excellent adsorption properties and removal efficiency towards Pb(II) was prepared by a facile grafting polymerization reaction in aqueous medium using natural biopolymer sodium alginate (SA) as the main chains, sodium acrylate (NaA) as the monomers, and poly(vinyl alcohol) (PVA) as the semi-IPN component. FTIR, TGA and SEM analyses confirm that NaA monomers were grafted onto the macromolecular chains of SA, and PVA chains were interpenetrated and entangled with the crosslinked network. The incorporation of PVA facilitates to form pores on the surface of hydrogel adsorbent. The semi-IPN hydrogel containing 2 wt% of PVA exhibits high adsorption capacity and fast adsorption rate for Pb(II). The best adsorption capacity reaches 784.97 mg/g, and the optimal removal rate reaches 98.39% (adsorbent dosage, 2 g/L). In addition, the incorporation of PVA improved the gel strength of hydrogel, and the storage modulus of hydrogel increased by 19.4% after incorporating 2 wt% of PVA. The increase of gel strength facilitates to improve the reusability of hydrogel. After 5 times of regeneration, the adsorption capacity of SA-g-PNaA decreased by 23.2%, while the adsorption capacity of semi-IPN hydrogel only decreased by 10.8%. The adsorption kinetics of the hydrogel in the initial stage (the moment when the adsorbent contacts solution) and the second stage are fitted by segmentation. It is intriguing that the adsorption kinetics fits well with both pseudo-second-order kinetic model and pseudo-first-order model before 60 s, while only fits well with pseudo-second-order adsorption model in the whole adsorption process. The chemical complexing adsorption mainly contribute to the efficient capturing of Pb(II).

Purpose

Intracranial aneurysms (IA) comprise a multifactorial disease with unclear physiological mechanisms. The lysyl oxidase (LOX) family genes (LOX, LOX–like 1–4) plays important roles in extracellular matrix (ECM) reconstruction and has been investigated in terms of susceptibility to IA in a few populations. We aimed to determine whether polymorphisms in LOX family genes are associated with susceptibility to IA in a Chinese population.

Methods

This case-control study included 384 patients with IA and 384 healthy individuals without IA (controls). We genotyped 27 single nucleotide polymorphisms (SNPs) of LOX family genes using the Sequenom MassARRAY® platform. These SNPs were adjusted for known risk factors and then, odds ratios (OR) and 95% confidence intervals (CI) were evaluated using binary logistic regression analysis.

Results

The result showed that LOX rs10519694 was associated with the risk of IA in recessive (OR, 3.88; 95% CI, 1.12–13.47) and additive (OR, 1.56; 95%CI, 1.05–2.34) models. Stratified analyses illustrated that LOX rs10519694 was associated with the risk of single IA in the recessive (OR, 3.95; 95%CI, 1.04–15.11) and additive (OR, 1.64; 95%CI, 1.04–2.56) models. The LOXL2 rs1010156 polymorphism was associated with multiple IA in the dominant model (OR, 1.92; 95%CI, 1.02–3.62). No associations were observed between SNPs of LOXL1, LOXL3, and LOXL4 and risk of IA.

Conclusion

LOX and LOXL2 polymorphisms were associated with risk of single IA and multiple IA in a Chinese population, suggesting potential roles of these genes in IA. The effects of these genes on IA require further investigation.

Published: July 2021

Objective

To investigate the association of dynamic weight change in adulthood with leukocyte telomere length among U.S. adults.

Methods

This study included 3,886 subjects aged 36-75 years from the National Health and Nutrition Examination Survey (NHANES) 1999-2002 cycle. Survey-weighted multivariable linear regression with adjustments for potential confounders was utilized.

Results

3,386 individuals were finally included. People with stable obesity had a 0.130 kbp (95% CI: 0.061-0.198, P=1.97E-04) shorter leukocyte telomere length than those with stable normal weight (reference group) during the 10-year period, corresponding to approximately 8.7 years of aging. Weight gain from non-obesity to obesity shortened the leukocyte telomere length by 0.094 kbp (95% CI: 0.012-0.177, P=0.026), while normal weight to overweight or remaining overweight shortened the leukocyte telomere length by 0.074 kbp (95% CI: 0.014-0.134, P=0.016). The leukocyte telomere length has 0.003 kbp attrition on average for every 1 kg increase in weight from a mean age of 41 years to 51 years. Further stratified analysis showed that the associations generally varied across sex and race/ethnicity.

Conclusions

This study found that weight changes during a 10-year period was associated with leukocyte telomere length and supports the theory that weight gain promotes aging across adulthood.

Context

Hypothalamic obesity (HO) is a severe complication following craniopharyngioma, but studies regarding the sequelae in adult-onset patients with craniopharyngioma are sparse.

Objective

The objective of the study was to describe weight changes after surgical treatment in adult-onset craniopharyngioma patients and to analyze risk factors for postoperative weight gain and HO.

Subjects and Method

A retrospective analysis was conducted of 120 adult-onset patients who underwent surgery for craniopharyngioma and follow-up at the institution of the authors between January 2018 and September 2020. Clinical characteristics, anthropometric data, image features, treatment modalities, and endocrine indices were collected. Multivariable logistic regression analysis was used to identify independent risk factors for postoperative weight gain and HO.

Results

Forty-nine (40.8%) patients had clinically meaningful weight gain (≥5%) in a median follow-up time of 12.0 months (range 1.0–41.0 months) after surgery. The mean postoperative weight gain in this subgroup was 17.59 ± 12.28 (%). Weight gain continued in the first year following surgery. Patients with lower preoperative BMI [OR 0.78, 95% CI (0.67–0.90), P = 0.001] and the adamantinomatous subtype [OR 3.46, 95% CI (1.02–11.76), P = 0.047] were more likely to experience postoperative weight gain ≥5%. The prevalence of HO was 19.2% preoperatively and increased to 29.2% at last follow-up postoperatively. Only preoperative BMI [OR 2.51, 95% CI (1.64–3.85), P < 0.001] was identified as an independent risk factor for postoperative HO.

Conclusions

HO is a common complication in patients with adult-onset craniopharyngioma. Patients with higher preoperative BMI had a greater risk for developing HO postoperatively.
