AIM: To evaluate the safety and efficacy of augmented trabeculotomy with Ologen versus perfluoropropane in management of pseudophakic glaucoma.
METHODS: This is a comparative randomized study included 57 pseudophakic eyes of 57 patients with medically uncontrolled open angle glaucoma (OAG). Twenty-nine patients were allocated in group I (trabeculectomy with Ologen; trab-ologen group), while 28 patients were assigned in group II (trabeculectomy with perfluoropropane gas bubble; trab-C3F8 gas bubble group).
RESULTS: The intraocular pressure (IOP) was significantly reduced in both study groups at all postoperative follow up intervals (1wk, 3, 6, 12, 18, 24, 30 and 36mo, P<0.001). The differences between the mean IOP values of both groups remained statistically insignificance during the early 12 months of follow up. However, the trab-ologen group achieved a statistically significant reduction over the trab-C3F8 gas bubble group during the last 24 months of follow up.
CONCLUSION: Augmentation of trabeculectomy with either Ologen implant or perfluoropropane gas bubble are associated with strict long term IOP control and evident safety in medically-uncontrolled pseudophakic eyes with OAG.

AIM: To report the clinical characteristics and diagnostic procedures used in patients with spasm of the near reflex (SNR), in order to present common investigation strategies and diagnostic pitfalls.
METHODS: Retrospective case series of twenty-two patients, mainly children, with SNR or accommodation spasm (AS). AS was diagnosed on the basis of blurred vision and a difference of >2 dioptres between manifest and cycloplegic retinoscopy. If esotropia and miosis were present, the patients were diagnosed with SNR. All patients underwent visual acuity testing, orthoptic evaluation, assessment of refraction before and after cycloplegia, and dilated fundoscopy. Additional diagnostic investigations, such as neuroimaging, lumbar puncture (LP), electrophysiology and blood tests, were also recorded. Screen use among children was assessed in hours per day.
RESULTS: There were 19 female and 3 male patients (age range 7-33y, median=10y). Seventeen patients had AS and 5 patients had SNR, with episodic blurry vision and headaches being the most common symptoms. Brain neuroimaging was performed in six patients (27%), although only one had a history of brain trauma. Two of those patients underwent visual evoked potentials and three also underwent LP and received intravenous steroid therapy. The majority of patients (90%) reported prolonged daily screen time (>2h/d), and in 55% of cases there were concurrent social problems or psychological triggers. Treatment consisted of careful explanation of the condition, atropine 1% eye drops and full cycloplegic correction by means of bifocal glasses.
CONCLUSION: The diagnosis of SNR and AS may be challenging, because symptoms are usually intermittent and nonspecific, and a large number of patients are often subjected to redundant and potentially time-consuming examinations and treatment, that may exaggerate the underlying psychological disorder. Hence, detailed clinical testing and assessment of psychosocial profile is necessary, in order to avoid unnecessary investigations. Neuroimaging should be performed only in selected cases. Finally, due to prolonged screen use SNR and AS may become more frequent in the future.

AIM: To evaluate the survival outcomes of patients with lacrimal gland adenoid cystic carcinoma who underwent eye-sparing surgery combined with 125I seed implantation radiotherapy or local external γ-ray radiotherapy.
METHODS: In this retrospective comparative case series, the clinical records of 27 primary and 8 recurrent patients were reviewed. Univariate and multivariate analyses were used to identify risk factors associated with distant metastasis (DM), and the overall survival (OS) after the initial surgery was analyzed.
RESULTS: The median follow-up after radiotherapy was 36mo (range 6-120mo). At the last follow-up after radiotherapy, 26 (74.3%) patients had no evidence of disease, 7 (20%) patients had DM, 2 (5.9%) patients died of DM, and 1 patient with DM was lost to follow-up. Univariate analyses showed that duration of symptoms, bone destruction, T stage classification, and wide excision surgery were risk factors influencing DM (P<0.05). The 5-year and 10-year OS rates after the initial surgery were 95.8% and 79.9%, respectively. The 5-year DM-free survival and disease-free survival rates after radiotherapy were 66.4% and 52.7%, respectively.
CONCLUSION: 125I seed radiotherapy and local external γ-ray radiotherapy may have similar therapeutic effects in preventing DM. Patients with T1/T2 stage disease have a better prognosis than those with T3/T4 stage disease.

AIM: To investigate the clinical manifestations, diagnostic approaches, treatments, and outcomes of intraocular lymphoma.
METHODS: In this retrospective study, 16 patients (28 eyes) with intraocular lymphoma were recruited in the Department of Ophthalmology, Peking Union Medical College Hospital, from 2004 to 2019. All patients underwent comprehensive ophthalmic examinations. Vitreous specimens of 13 patients were sent for cytopathology examination and other adjunctive diagnostic procedures. Three patients were diagnosed with intraocular lymphoma according to analysis of the histopathological results of systemic lymphoma by one clinician. Twenty-three eyes were treated with intravitreal administration of methotrexate, 4 eyes could not receive ocular treatment due to life-threatening lymphoma, and 1 eye did not require ocular treatment because the fundus lesions regressed after systematic chemotherapy.
RESULTS: In 28 eyes, 25 eyes were diagnosed with vitreoretinal lymphoma, and 3 eyes were diagnosed with ciliary body lymphoma, all of which were non-Hodgkin diffuse large B cell lymphomas. The final visual acuity improved in 15 eyes (54%), remained unchanged in 5 eyes (18%), and decreased in 8 eyes (29%). Anterior segment inflammation disappeared or reduced in 8 and 5 eyes, respectively; and 15 eyes had no anterior segment reaction. Twenty eyes had mild vitreous opacity, 1 eye had mild vitritis, and 7 eyes had pars plana vitrectomy combined with silicone oil tamponade. Fundus lesions disappeared in 9 eyes and were relieved in 5 eyes; 4 eyes showed no changes, and the remaining 10 eyes' fundus were normal.
CONCLUSION: The clinical manifestations of intraocular lymphoma are diverse, and the misdiagnosis rate is high. Cytopathological analysis of vitreous is one of the gold standards for the diagnosis. Immunohistochemistry, gene rearrangement and flow cytometric immunophenotypic analysis can improve the diagnostic rate. Ocular chemotherapy or radiotherapy regimens may preserve visual acuity, and a multidisciplinary team can provide individualized treatment for the patients.

The incidences of open angle glaucoma (OAG) and high myopia are increasing concomitantly. Considering the aging population and concurrent rapid increase in the number of individuals with myopia, the risk of visual defects caused by highly myopic OAG is likely to increase dramatically over the next few decades. However, precise screening and diagnosis of OAG is challenging because of the tilt and rotation of the optic disc, as well as extensive β-zone parapapillary atrophy in highly myopic eyes. Recent advances in optical coherence tomography (OCT) and OCT angiography (OCTA) technologies imply that both modalities are promising tools for the detection of highly myopic OAG. Notably, the diagnosis of OAG remains to be determined with the longitudinal changes of functional damages (e.g. visual field defect, visual electrophysiological changes). We herein describe some aspects of microvascular and microstructural pathology in patients with highly myopic OAG and proposes a framework for the development of novel diagnostic and therapeutic strategies.

Published: March 2021

A atividade econômica da indústria gera benefícios, como crescimento econômico, e malefícios, como resíduos descartados no meio ambiente. A possibilidade de mitigar os malefícios da atividade industrial, por meio de inovações sustentáveis, posiciona-se como tema de interesse para a sociedade. Neste contexto, esta pesquisa analisa o escopo das inovações socioambientais que a siderurgia brasileira implementa para mitigar a geração de resíduos sólidos. O desenvolvimento da pesquisa foi baseado em um estudo de caso na Usiminas, uma das maiores siderúrgicas da América do Sul, utilizando técnicas de análise de documentos e entrevistas com representantes da empresa. Os dados indicam que, por meio de um grupo multidisciplinar, a empresa desenvolveu quatro produtos que utilizam a escória da produção de aço com oxigênio como insumo. Embora o produto seja patenteado e seu valor seja negociado, o modelo de negócios adotado foi projetado para contribuir com o município. Como contrapartida, o beneficiário municipal desenvolve projetos para proteger as fontes de água. Dessa forma, as inovações tecnológicas podem transformar o resíduo dos processos da indústria em produtos que beneficiam o meio ambiente e a sociedade.

Published: March 2021

Diversos bancos oferecem aos usuários a possibilidade de acessar e realizar transações pela internet. Porém, as contas digitais não são apenas serviços de “internet/mobile banking”, são contas em que não há interação do consumidor com um funcionário em uma agência física. Na última década, a inovação digital tem-se destacado, observado pelo surgimento de novas tecnologias, plataformas e infraestruturas, com amplas implicações organizacionais e políticas. O objetivo deste artigo foi avaliar como os benefícios das contas bancárias digitais se enquadram no modelo de aceitação de tecnologias, proposto por Venkatesh e Davis (1996), considerando a estrutura de valor dos bancos selecionados. Trata-se de um estudo qualitativo e exploratório, apoiado pela metodologia de estudo de caso, com dados primários coletados de maneira virtual, a partir de uma amostra composta por correntistas dos bancos selecionados. Os resultados demonstraram que a isenção de taxas bancárias, comodidade e facilidade para movimentação de conta são os principais atributos valorizados em uma conta digital. Ademais, embora o modelo de aceitação de tecnologias não tenha sido testado estatisticamente, o estudo evidenciou que é eficaz para pesquisas bancárias, sendo confirmada a aceitação da tecnologia de bancos digitais por meio dos resultados referentes a utilidade e facilidade de uso percebido.

Authors: Llanos Redondo Andrés , Rangel Navia Heriberto José , Aguilar Cañas Sandra Johanna , Tamara Moncada Viviana Andrea , Crespo Pérez Nora Cristina
Published: March 2021

Introducción. La anquiloglosia es una condición limitante que en algunos casos no interfiere en la lactancia y genera adaptaciones anatomofisiológicas del frenillo al seno materno, el cual se presenta más elástico y menos fibroso. El objetivo fue establecer si existe relación entre las alteraciones del frenillo lingual y la lactancia materna.
Materiales y métodos. Investigación descriptiva correlacional de corte transversal. La población objeto de estudio fue evaluada mediante el Protocolo de evaluación del frenillo de la lengua con puntuación para bebés.
Resultados. Se identificó un 29% de prevalencia en las alteraciones del frenillo lingual. La anatomofisiología del frenillo y la succión son dependientes y estadísticamente significantes.
Conclusiones. La lactancia materna y la anatomofisiología del frenillo lingual alterado, conocido como anquiloglosia, guardan una fuerte relación de dependencia, ya que ante la presencia de anquiloglosia no se produce un agarre adecuado del pezón en la cavidad oral. No obstante, en algunos casos se ha comprobado que los lactantes realizan procesos de adaptación para suplir las dificultades en la movilidad lingual y alimentarse.

Published: March 2021

Starch is one of the basic ingredients for making edible films (edible coatings), but it tears easily, so it needs the addition of plasticizers. This study aims to make edible film from durian seed starch (Durio zibethinus Murr) with the addition of plasticizers, glycerol and sorbitol and determine its characterization. The results showed that the best edible film was produced by adding 2.5% (w / v) of glycerol and 2% (w / v) of sorbitol. The physical characteristics of the edible film are respectively: thickness 0.1700 mm and 0.1633 mm, tensile strength 0.008 Kgf / mm2 and 0.010 Kgf / mm2, percent elongation 42.76% and 37.13%, elasticity 0.0202 and 0.0272. The chemical characteristics of edible film include: water absorption test of 58.22% and 60.43%, solubility of 40.89% and 26.42%, water vapor transmission rates of 0.2275 g / jamm2 and 0.3127 g / jamm2, and pH 6.90 and 7.85. The results of functional group analysis (FTIR) show that the process of making edible films in this study is a physical mixing process. The shelf life of edible films at room temperature is 5 days and at cold temperature for 7 days. The biodegradability test showed that the edible film in this study could be completely degraded within 7 days. This shows that the durian seed starch edible film is an environmentally friendly packaging.

Published: March 2021

During the last five decades, a huge amount of water pollutants has been recorded in all water resources around the world. Therefore, the water quality has become an important indicator affecting the vitality and productivity of plants, which requires an effective technique to monitor all these pollutants. The main objective of this study is to assess the validity of groundwater for wells located within the boundaries of the Green Belt area in Karbala city/Iraq for irrigation of palm and olive trees. Whereas, the use of saline groundwater as an alternative to available fresh water will promote the sustainable development of water resources. The technique of Water Quality Index (WQI) is a reliable and widely used tool for assessing water quality for various sources, including groundwater. In this study, the Canadian water quality index (CWQI) model was applied to provide a database for planning and monitoring the quality of groundwater in wells located in the study area. Groundwater samples were taken from these wells and tested to find seven parameters which were; pH, CL, Mg, HCO3, EC, Na and Ca. The CWQI values of groundwater for the studied wells ranged from 30 to 35. According to the CWQI scale, the groundwater of all wells is classified as poor water. Therefore, the groundwater of all wells in the study area must be treated before it is used for the purpose of irrigation of palm and olive trees. This study concluded that to ensure good irrigation management in the study area, future changes of groundwater in the study area must be monitored.

This article provides comparison analysis between 1950–1959’s and 2000–2009’s periods for duration and schedule dates of awakening, spreading and hibernation phases for Spermophilus pygmaeus populations located in the Caspian Depression (by example of Astrakhan Oblast). We learned that within a period of maximum temperature rise in February 2000–2009’s durations of S.pygmaeus’ populations of every phonological phase have shortened and been rescheduled with earlier dates (in comparison to 1950–1959’s). The study also shows that these changes caused its population reduction on the Caspian Depression’s territory.

The relevance of this topic is determined by the significance of the struggle of the Palestinian people for the foundation of their own state. Despite the huge number of publications on this topic, it cannot be considered exhausted due to the fact that new actors are emerging in this process, which respond in their own way to the internal and external challenges that arise around the problem of Palestinian state-building. The article is devoted to identifying the role and significance of the Hamas movement in the foundation of a Palestinian state. The study focuses on the ideology of this movement, the directions and mechanisms of its practical activities, the lack of unity among the political elite of Palestine, which negatively affects the process of strengthening Palestinian sovereignty and leaves little chance for achieving the goal of foundation of a Palestinian state. Having analyzed the ideological tenets of Hamas and its methods of political struggle, the authors come to conclusion that until the label of a terrorist organization is not removed from this organization, it would be impossible to neutralize the contradictions among the Palestinian elite in order to consolidate and make progress in resolving the Palestinian-Israeli conflict without the involvement of the movement in the negotiation process. Methodologically, this article is based on the theoretical approaches of both Russian and foreign researchers. The article is based on general philosophical and socio-humanitarian methods. The paper uses empirical data obtained from open sources.

World of children’s experiences, meanings, values, emotions is still an unexplored area for social sciences. Particularly interesting are children’s experiences of being a member of the modern family. In the literature a lot is written about transformations of the family as a social group, it’s functions, tasks, risks and emerging alternative entities in the form of non-normative family practices are analyzed. Much is said about the phenomenon of orphanhood also as a consequence of the crisis experienced by the family. In the analysis of the problem of orphanhood attention is primarily placed on social orphanhood as the most visible and verifiable in statistics expressing the number of children living in residential care or foster care family forms. Little is mentioned about emotional orphanhood. The issue of emotional orphanhood is complex, which makes it extremely difficult study it. Definitions found in the literature are often not unequivocal. Emotional orphanhood can be divided on psychological, spiritual, occult, caused by emigration. Definitions are based on different criteria: emotional rejection, narrowing or lack of realisation of parental functions, temporary disconnection of family members. The common part of them is the fact that every one of them describes a child that lives without satisfying basic emotional needs (love, intimacy, acceptance, understanding) due to weakening or destruction of emotional bonds.

The article is an attempt to conceptualize the initial approach to the study of local patterns of social solidarity in the event of natural hazards and disasters, based on selected findings by researchers of disasters and researchers of local communities. The conceptualization is an attempt to integrate the psychological perspective and the socio – cultural analysis of social reaction to natural hazards and disasters, as the essential framework for the discussion on local patterns of social solidarity. Special attention is given to determine how informal factors (eg. family condition, the role of neighborhood and social self-help network) and institutionalized factors (the role of NGOs and local institutions, including social assistance and local government) affect the specific patterns of solidarity in the event of natural hazards and disaster. Important in this analysis is the question about socio – cultural indicators that the strength of the solidarity of the local community or its weakness, which manifests itself in: 1 / areas of exclusion and marginalization in the local space and consolidating a sense of loss and marginalization of certain groups or categories of people, 2 / the phenomenon of erosion ties between local elites and citizens and weakening ties between organizations working in the area, 3 / shift by the citizen and local leaders responsibility for decisions on the structures and institutions external to the community.

Within 50 years of socialist realism in Poland, Polish forms of a social subclass and the culture of poverty distinguishing it appeared and became established in the specific community of State- Owned Farms. In the face of the lack of data update for over 10 years, the achievements of Polish researchers in this field so far leave many intriguing questions unanswered. The most important questions became an inspiration to make in the year 2011 an analysis of the study of the case of Kubanki village in the Region of Western Pomerania. The data gathered in this research have made it possible to diagnose the lack of a widespread occurrence of many indicators of the complex syndrome of the culture of poverty in that community. The data show concrete factors, which could and can block the process of development of the discussed phenomenon in the practice of social life, as well as eliminate individual detailed characteristics of the syndrome of the culture of poverty. In research practice, different types of indirect evidence have led to direct association of certain conditions occurring in Kubanki and in the surroundings with improvement of the residents’ life situation. These circumstances are directly connected with a broadly understood human activity and its conditions. In the discourse on contemporary social policy, the aspect of activation of individuals increases in popularity. This activation is to be an important factor on the path of transition from welfare state to welfare society. Observations made during the research mentioned above are placed into the context based on these guidelines. In accordance with these observations, in the light of the concept of the culture of poverty, the “overcoming” of this syndrome in the community can be done thanks to a far-flung activation of its members. As a result, this can lead to the transition from the culture of poverty, dependence on welfare, and so-called acquired helplessness to the culture of self-reliance, independence, and resourcefulness. The goal of the text is depiction of inspirations (determinants) in the scope of activation of this process.
