Published: August 2020

It is important to arbitrarily manipulate optical intensity, an important degree of freedom to light, on microscales, which is a fundamental requirement for integration and miniaturization of optical devices. Metasurfaces have shown unprecedented capabilities for manipulating light in terms of phase, intensity, and polarization. Here, an ultrathin metasurface composed of silver nanorods illuminated by linearly polarized light is demonstrated to manipulate optical intensity in subwavelength scales. By modulating rod orientations, gradient reflectance of light can be achieved on dual-wavelength regimes with contrast reflection intensities. Further, a nanorod metasurface, embedded with a picture of a panda profile, is experimentally designed for grayscale imaging, and the measurements demonstrate that two complementary grayscale images can be displayed at 633 and 900 nm. The grayscale imaging by a proposed ultrathin metasurface with dual-wavelength, complementary, and subwavelength-resolution characteristics provides a simple but efficient way for tailoring optical intensity on subwavelength scales, which is promising for a variety of applications such as encryption and decryption, display, information security, and optical communication.

Abstract: Tuberculosis is an infectious disease and according to the World Health Organization, the number of deaths due to the disease may be related to the renunciation of treatment, as it favors maintenance of the transmission chain and increases the bacterial resistance to the first drugs choice. This study aimed to evaluate the recurrence of tuberculosis in the city of Juazeiro do Norte-CE in the period from 2015 to 2018 regarding the sociodemographic profile of patients, comorbidities, number of contacts, sputum smear, sputum culture. This is a cross-sectional retrospective, descriptive study. Twenty-two cases of recidivism, with a higher prevalence of males, were observed in brown individuals with low educational level. The most prevalent form was pulmonary. The prevalence of Tuberculosis is still a challenge for public health, recidivist cases deserve to be evaluated with more criteria taking into account socioeconomic and demographic aspects. Keywords: Recidivism. Resistance. Tuberculosis.

Published: August 2020

CONTEXT:The International Liaison Committee on Resuscitation Neonatal Life Support Task Force reviewed evidence for the duration of cardiopulmonary resuscitation (CPR) for newborns immediately after birth.OBJECTIVE:To summarize evidence for ongoing CPR on the outcomes of survival, neurodevelopment, and the composite of survival without moderate or severe neurodevelopmental impairment (NDI).DATA SOURCES:Medline, Embase, Evidence-Based Medicine Reviews, Cumulative Index to Nursing and Allied Health Literature, and Scientific Electronic Library Online were searched between inception and February 29, 2020.STUDY SELECTION:Two independent reviewers selected studies of newborns with at least 10 minutes of asystole, bradycardia, or pulseless electrical activity for which CPR is indicated.DATA EXTRACTION:Two independent reviewers extracted data and appraised the risk of bias.RESULTS:In 16 eligible studies, researchers reported outcomes of 579 newborns born between 1982 and 2017. Within individual studies, 2% to 100% of infants survived to last follow-up (hospital discharge through 12 years). Summarized across studies, 237 of 579 (40.9%) newborns survived to last follow-up. In 13 studies, researchers reported neurodevelopmental outcomes of 277 newborns. Of these, 30 of 277 (10.8%) survived without moderate or severe impairment, and 240 of 277 (87%) met the composite outcome of death or NDI (191 died and 49 survived with moderate or severe impairment).LIMITATIONS:There was very low certainty of evidence because of risk of bias and inconsistency.CONCLUSIONS:Infants with ongoing CPR at 10 minutes after birth are at high risk for mortality and neurodisability, but survival without moderate or severe NDI is possible. One specified duration of CPR is unlikely to uniformly predict survival or survival without neuroimpairment.

Authors: Dalström Stig , Kolanowska Marta 
Published: August 2020

A new species of Chiloschista Lindl. from western Thailand is described and illustrated with a line drawing and photographs. It is compared with the sympatric C. parishii Seidenf., from which it differs in having larger flowers, which are 11–12 mm across versus 8–10 mm across for C. parishii. The new species also distinctly differs in having widely spreading rostellum lobes and a viscidium that is as broad as the length of the stipe, as opposed to downward directed rostellum lobes and a viscidium that is distinctly narrower than the length of the stipe for C. parishii. The same distinguishing features separate the new species from the similarly colored C. trudelii Seidenf., which has inward-directed rostellum lobes and a viscidium that is distinctly narrower than the length of the stipe.

Published: August 2020

Some coral bleaching event related to climate variability (ENSO or IOD) lead to coral mortality resulted in ecosystem damage and decreased in ecosystem health. Artificial reef is one of management efforts adopted by stakeholders to restore coral reef condition. Successful artificial reef could extend coral coverage and provides a new habitat for several marine organisms and could divert anthropogenic pressure on natural coral ecosystems. The current research aims are to identify the impact of artificial reef installment on ecosystem and fisheries. Three indicators for ecosystem were determined, such as an increase in coral cover, biofouling organism and fish abundance and number of fish species. The indicator to measure artificial impact on fisheries is fish production after installment. Data collection were done during 2017 around Bali area, including the occurrence of coral bleaching, the number of artificial reef installed and the case of positive impact of artificial reef. The list of indicator data was done, then the data were analyzed to measure any changes occurred after artificial reef installment. Results show that artificial reef installment has a significant impact on increasing coral cover, fouling organism, fish abundance and species richness; however the effect of artificial reef installment could not directly quantify on fish production due to unavailability of monitoring data.

Published: August 2020

A expansão do uso das tecnologias digitais de informação e comunicação causa impacto social e quebra as barreiras físico-geográficas, permitindo o surgimento de uma nova cultura digital. Esse fato exige uma posição crítica em relação às tecnologias, bem como a revisão das formas tradicionais de ensino. Metodologias ativas de aprendizagem e as possibilidades trazidas com a aplicação das novas tecnologias digitais em contexto educacional são forças que se demonstram importantes neste cenário (Garbin; Oliveira, 2019). Neste contexto, este artigo analisará os projetos propostos pelos alunos de Licenciatura sob dois prismas: a articulação dos conteúdos curriculares para a resolução de um problema e a utilização dos princípios das metodologias ativas no cumprimento das etapas do projeto. O cenário escolhido foi uma universidade no Estado de São Paulo durante o desenvolvimento de um processo de aprendizagem baseado em projetos com os alunos, estabelecido em seu currículo.. Para tanto, foram selecionados aleatoriamente quatro projetos desenvolvidos durante o segundo ano dos cursos de Licenciatura em Matemática e Pedagogia. A análise dos dados baseou-se na averiguação de três aspectos: problema identificado; protótipo; interdisciplinaridade. Foi possível perceber que os projetos desenvolvidos geraram práticas pedagógicas que preconizam o perfil de um professor criativo e crítico, que busca atender às necessidades de seus alunos, de acordo com o contexto educacional.
Afrodescendientes, racialización y políticas de las sensibilidades en Argentina
Authors: Cervio Ana Lucía 
Published: August 2020

Este artículo indaga algunas conexiones entre políticas de las sensibilidades y prácticas de racialización. Tomando por caso la problemática de afrodescendientes en Argentina, el propósito general es ofrecer una discusión sobre las sensibilidades, entendidas como estructuras del sentir que traducen las tramas de la dominación social en la vida cotidiana. Desde esta perspectiva, interesa analizar cómo las sensibilidades interceden en las prácticas de racialización que acompañan y hacen posible el desarrollo capitalista en sus aspiraciones neocoloniales. Asumir este posicionamiento teórico supone considerar que las sensibilidades regulan, entre otros aspectos, los modos racializados de observar/sentir/percibir el mundo que tienen los sujetos, y que se ponen en juego en forma radical en contextos interculturales.
Para alcanzar dicho objetivo, en primer lugar, se presenta el abordaje teórico-epistémico que orienta al análisis, discutiendo un conjunto de inflexiones analíticas que conectan las prácticas de racialización con las políticas de las sensibilidades. Seguidamente, con base en un análisis documental-bibliográfico, se exploran las clasificaciones raciales y sociales operantes en Argentina, indagando en los procesos de subalternidad configurados en torno a la figura del “negro” desde el surgimiento del Estado-Nación hasta la actualidad. Se concluye que el “maniqueísmo categorial” imperante en las clasificaciones raciales, junto con la “negrificación” del mundo subalterno que se afianza desde mediados del siglo XX, tornan relevante la discusión sobre la interculturalidad como problema epistémico y proyecto político.

Published: August 2020

Aim. To assess the dynamics of coagulation parameters and the influence of its initial values on the development of postoperative thrombohemorrhagic complications in male and female patients undergoing large joint arthroplasty and received combination hemostatic and anticoagulant therapy.
Methods. A retrospective analysis of the medical records (n=253) of patients with arthroplasty, were divided into two groups based on the time differences between prescription of hemostatic and anticoagulation therapy. The first group includes 145 patients (57.31%, 112 women and 33 men) with time differences 17 h, and the second group includes 108 patients (42.68%, 78 women and 30 men) with time differences 1824 h. The dynamics of coagulation test results were analyzed, and the influence of its initial value on the risk of postoperative thrombosis or bleeding was assessed.
Results. Thrombohemorrhagic complications were recorded in 27 (10.67%) patients, of which 22 (81.48%) were observed in group 1. In the first group, thrombosis developed in regimens with tranexamic acid (p=0.038) with 2.2 times higher incidence than in group 2 (p=0.023). The risk of thrombosis of women in the group 1 was increased by an initially low level of international normalized ratio [relative risk (RR) 13.333, p=0.00032] and activated partial thromboplastin time (RR=5.8, p=0.037). The risk of bleeding in group 1 increased by an increasing preoperative level of activated partial thromboplastin time (RR=18, p=0.0012 and RR=28, p=0.00022, respectively) for all patients and by a decreasing fibrinogen level (RR=23.25, p=0.00065) and platelets count (RR=10.2, p=0.038) for women.
Conclusion. To minimize the risks of thrombosis and bleeding after arthroplasty, especially in patients with initial deviations of hemostasis parameters from the norm, and, in particular, when using tranexamic acid as a hemostatic agent, it is recommended to observe the time interval between hemostatic and anticoagulant pharmacotherapy for at least 18 hours.
Endovascular biometrics and engineering
Authors: Goloshchapov-Aksenov Roman S , Kicha Dmitry 
Published: August 2020

Aim. To study technical problems in the provision of endovascular care and to develop technological solutions for its improvement based on endovascular biometry.
Methods. For the period 20152019 an expert analysis of the results of endovascular treatment of 1546 patients with chronic lower limb ischemia was performed, in which it was not possible to perform lower limb revascularization according to the standard method using a guide catheter, guidewire and balloon catheter. The expert group included 5 interventional radiologists who performed endovascular procedures. The results were assessed by the effectiveness of revascularization using the developed innovative technology from a system of catheters of various diameters and stiffness in comparison with the results of using standard endovascular technique. Calculation of adequate statistical indicators and their reliability were undertaken using Statistica software (version 6.0).
Results. The critical and weak zones of the vascular bed were identified for the first time to substantiate the development of a technology for safe and effective endovascular revascularization. It has been established that technical difficulties in catheterization of vessels create the prevalence of atherosclerotic lesions and the limited technical capabilities of catheters and guidewires, which are manipulated under the conditions of increasing high friction with the vessel wall caused by tortuosity and atherosclerosis, the presence of weak and critical zones of the blood vessels, as well as a significant distance from the surgeon's hands to the area of medical manipulation, reaching 130200 cm. The developed innovative design from the catheter system ensured the effectiveness of endovascular lower limb revascularization in all patients (100%) using the femoral and brachial accesses compare to the standard technique of endovascular care (p 0.001).
Conclusion. Endovascular instruments offered on the domestic market do not guarantee the effective completion of revascularization. The technology of vascular catheterization developed based on endovascular biometry ensures the successful completion of revascularization in 100% of cases.

Published: August 2020

Aim. To study the structure of psychosocial maladjustment in chemical workers and assess the contribution of industrial and non-industrial risk factors in the formation of mental illness.
Methods. It was analysed of hygienic assessment of the leading harmful production factors chemical, physical, factors of severity and intensity of labor. During the periodic medical examination, the mental health status of 1,226 people was examined, with a focus on professional experience, mental hygiene aspects of production factors, as well as individual and personal characteristics of employees. Confidence intervals and standard errors estimating, the logistic regression models fitting were performed using R Statistical Software with significance level 0.05.
Results. The working environment hazards in organic synthesis included chemical risk factor, continuous noise exceeding the permissible exposure limit, emotional stress and life-threatening conditions (fire and explosion hazards in the work). The general assessment of working conditions was performed using clauses 5.15.11 P 2.2.2006-05-harmful working conditions of the second-third degree (3.23.3). Working conditions at all stages of the manufacturing process of pyroxylin powders were assessed as harmful to the third-fourth degree (3.33.4), including the chemical factor, the severity and intensity of work, fire and explosion hazards in the work. It was revealed the dependence of the development of psychosocial maladjustment on non-work-related factors (such as the level of education, marital status), conditional work-related factors (level of material security). Also, the dependence of the structure of pre-existing mental health condition on the work-related and developmental characteristics (work experience) of labor in chemical production was found.
Conclusion. Working conditions in the studied industries correspond to the 3rd harmful class, 2nd and 3rd degrees in the production of organic synthesis (3.23.3), while at the production of pyroxylic powders, it is close to dangerous (3.33.4); the structure and risk of the developmental process of employee maladjustment are determined by the feature effect of workplace hazards.
The treatment of sialolithiasis by sialolithotripsy
Authors: Aliyev S Z 
Published: August 2020

Aim. To study the effectiveness of treatment of sialolithiasis by sialolithotripsy.
Methods. Between 2015 and 2018, extracorporeal shockwave lithotripsy of salivary stones of 39 patients was performed in the Nasreddin Tusi Memorial Clinic. The stone was located in the submandibular gland and its duct for 33 patients and the parotid salivary glands and its duct for 6 patients. The average age of patients was 503.38 (between 22 and 77).
Results. Stone fragmentation as a result of sialolithotripsy was achieved in 36 (92.7%) of 39 examined patients (p=0.031). In 3 patients the stone was completely fragmented, but due to the narrow lumen of the main duct, it did not move away. In 3 patients with calculus size more than 2 cm, the stone was not fragmented. According to our results, the necessary effect was achieved in 85% of cases and was unachieved in only 15% of cases.
Conclusion. Given the complexity of the surgical treatment in patients with salivary stone and potential postoperative complications, especially with the stone localization within the parotid gland, we concluded that extracorporeal shockwave lithotripsy is a promising alternative treatment for patients with salivary stone.
