Authors: Mangueira Luciana 
Published: July 2022

Introdução: Retrospectivamente, a chegada europeia em terras brasileiras era precedida do ideal de um ambiente destituído de vulnerabilidades. No cerne das patologias que acometem esses povos, os dados históricos anteriormente contextualizados reforçam potenciais surtos epidêmicos, como o de 2009, provocado pelo vírus H1N1 e agora a COVID-19. Nesse contexto, apesar de existirem modelos organizacionais e adaptações em saúde para os povos indígenas, as elevadas taxas de óbito são mais uma confirmação de evidências recentes que demonstraram que a introdução de vírus nessas comunidades apresenta um número maior de mortes. Objetivo: abordar os impactos da pandemia do COVID-19 na população indígena tocantinense e identificar as principais vulnerabilidades enfrentadas pela população indígena do Tocantins. Método: O presente estudo se caracteriza como uma revisão integrativa que buscou apresentar análise crítica acerca da temática sobre o Impacto da COVID-19 nas Populações Indígenas do Tocantins, entre o período março de 2020 à abril de 2021. Resultados: Desde o primeiro caso, até 27 de abril de 2021, foram registrados pelo Ministério da Saúde 657 óbitos por COVID-19 na população indígena brasileira. No Estado do Tocantins, durante o mesmo período, foram confirmados 1.195 casos, destes, 10 morreram. Conclusão: A COVID – 19 na população indígena é um problema maior, pois os povos indígenas são mais vulneráveis as doenças infectocontagiosas devido aos seus costumes e hábitos de vida.

Authors: Oliveira da Silva Juliana , Carvalho Ferrão Pedro Emílio , Corrêa de Freitas Marcelo 
Published: July 2022

Introdução: A fenda palatina é uma das malformações congênitas de maior incidência e ocorre devido a falha na fusão dos processos frontonasais e maxilares durante a vida intrauterina, causando alterações na fala e anormalidades na função da tuba auditiva. O objetivo da palatoplastia é a reconstrução cirúrgica do palato com foco na restauração da fala. Metodologia: Foram realizadas pesquisas nas bases Pubmed e Scielo para publicações recentes. Não houve seleção com base na metodologia do estudo. Resultados e Discussão: A palatoplastia de von Langenback é utilizada para o tratamento de fissuras incompletas do palato secundário sem fissura labial ou comprometimento alveolar. A técnica de Veau-Wardill-Kilner é uma modificação derivada da técnica anterior. A técnica de dois retalhos é indicada apenas para fissuras palatinas estreitas. A zetaplastia de Furlow é mais usada para reparo de fendas submucosas e fendas isoladas. Conclusão: O tratamento cirúrgico das fissuras palatinas vem se aperfeiçoando há décadas e as técnicas de palatoplastias possuem, cada qual, suas particularidades quanto aos seus efeitos na fala e no crescimento maxilofacial.

Authors: Karningsih Putu , Kusumawardani Citra 
Published: July 2022

Railway is one of the popular modes of public transportation in Indonesia, but there are conditions where length of platform does not cover the entire length of the railway coach. This causes access in and out passengers must be added with tools such as staircase. The condition of staircase that is currently available is large and heavy, so to place the staircase right at the door of the railway coach takes a longer time. The initial survey conducted on 106 passengers obtained data 34% of respondents stated that the staircase currently available are less comfortable to use, in addition 32.1% of respondents stated that the available staircases are not adequate in terms of number and physical condition. Based on this background, the study aims to redesign the staircase that according to the needs of two user they are: train passengers and Indonesian Train Service Provider by using the multi-layer Quality Function Deployment. The result of this study shows that both users agree that the design of new stair design should consider anthropometry of passengers, safety features, easy to be move during use (portable and light weight).

Published: July 2022

Abstract
Background
Although students were removed from patient-facing settings at the beginning of the COVID-19 pandemic due to concerns of burdening teaching physicians and depleting personal protective equipment, some leaders suggest students can be effectively utilized when personnel resources may be scarce. There have been narrative discussions surrounding medical student involvement, but no studies exploring the attitudes of these students. The authors aim to quantify the degree to which factors influenced a medical student’s decision to or to not volunteer during the pandemic and to characterize medical students’ attitudes towards medical professionals’ duty to serve in a pandemic.
Methods
The authors developed and tested a secure web-based survey before distribution to students at 23 different US allopathic medical schools that did not graduate medical students early to aid in pandemic efforts between April and June 2020. Of the 599 students who completed the survey, 65.5% self-identified as female and were on average 25.94 years old (SD = 2.5). Multiple comparisons were made based on volunteer status. Ordinal scale questions were compared with the Mann Whitney U test, and the Chi-Squared test was used for categorical variables using R version 3.62.
Results
67.6% of students volunteered in pandemic relief activities and a majority of those students volunteered in non-patient-facing roles. Community service, new skills, and time commitment were top 3 influencing factors for students who volunteered, while risk to other, time commitment, and risk to self were top 3 influencing factors for students who chose not to volunteer. Compared to other specialties, students interested in primary care specialties agreed to a greater degree that physicians have a duty to serve in pandemic relief efforts.
Conclusions
Medical students who volunteered cited self-serving factors and altruistic values as significant motivators. Students who did not volunteer were significantly more concerned with risks of COVID-19 exposure. However, medical students in general agreed that students should be allowed to volunteer in COVID-19 related relief efforts. As large areas of the United States continue to experience increases in COVID-19 cases, institutions should involve medical students in balancing the level of acceptable risk with the educational benefits.

Authors: Liu Fang , Feng Yongxin 
Published: July 2022

Abstract
Sparse code multiple access (SCMA) is an emerging technology developed to meet the requirements of 5G and 6G communications and improve the spectral efficiency of systems. The key behind SCMA technology is the design of its codebook method, particularly the design of the mother codebook method, which forms the basis of excellent user codebook design. Considering the limitations of existing mother codebook methods, a constellation evolution mother codebook design method is proposed here. Odd and even constellations are derived using the proposed method, and a multi-dimensional rotation angle is established. Then, the excellent mother constellations (mother codebook) are reconstructed. The proposed mother codebook design method demonstrates excellent performance in terms of the bit error rate and is found to be superior to existing codebook methods. It can provide a universal mother codebook for user codebooks, thus yielding excellent codebooks for efficient SCMA applications and establishing a technical basis for efficient 5G and 6G applications.

Abstract
In order to effectively remove the mixed noise, a novel algorithm for image reducing noise combined Pulse Coupled Neural Networks (PCNN) and regularization of Perona-Malik equation (P-M equation) is put forward. Firstly, the positions of impulse noise pollution are located by using PCNN, and the first stage adaptive noise filtering is applied according to the result of noise detection. Secondly, the multi-direction information median filtering is applied according to the local neighborhood noisy information. And then the Gaussian noise in the image is denoised by utilizing the regularization P-M diffusion equation. The theoretical analysis and experimental results show that the proposed algorithm needs no detection threshold, which has higher accuracy in the noise detection, is effectively able to remove the mixed noise, and can preserve the image details and the edges as well. The proposed algorithm has better subjective vision effect and objective quality than the wiener filter, median filter and other related algorithms. This algorithm put up better filter performance, high signal-to-noise ratio, denoising ability and strong adaptability.

Authors: Lin Ke-Feng , Lin Shih-Sung , Chen Ping-Nan 
Published: July 2022

Abstract
Background:
During the COVID-19 pandemic, which emerged in 2020, many patients were treated in isolation wards because of the high infectivity and long incubation period of COVID-19. Therefore, monitoring systems have become critical to patient care and to safeguard medical professional safety.
Objective:
The user interface is very important to the surveillance system; therefore, we use web technology to develop a system that can create an interface based on user needs. When the surveillance scene needs to be changed, the surveillance location can be changed at any time, effectively reducing costs and time required, so that patients can achieve timely and appropriate goals of treatment.
Methods:
ZigBee was employed to develop a monitoring system for intensive care units (ICUs). Unlike conventional GUIs, the proposed GUI enables monitoring of various aspects of a patient, and the monitoring interface can be modified according to user needs. A simulated ICU environment monitoring system is designed to test the effectiveness of the system. The simulated environment and monitoring nodes were set up at positions consistent with the actual clinical environments to measure the time required to switch between monitoring scenes or targets on the GUI.
Results:
A low-cost system that can construct ZigBee-simulated graphical monitoring interfaces on demand was proposed in this study. The system can effectively overcome the limitations of conventional design methods for monitoring interfaces.
Conclusion:
This system can be used to simultaneously monitor the basic physiological data of numerous patients, enabling nursing professionals to instantly determine patient status and provide appropriate treatments. The proposed monitoring system can be applied to remote medical care after official adoption.

Published: July 2022

Abstract
AimsIn time to the climate changes occurring in the recent decades, studies on the assessment of the influence of climatic factors on the changing natural ecosystems are becoming particularly relevant. This study assesses the relationship between vegetation response to climate aridization and the effect of these changes on soil properties, which is crucial for understanding the sustainability of steppe among the trend toward further global warming. Methods The study demonstrates the influence of climatic factors on the changes in plant biodiversity and biomass, the dynamics of the total stock and the rate of return of chemical elements to the upper soil horizons with the plant organic matter. The chemical composition of soils of different types of steppe was studied, and the effect of changes in vegetation cover on the variability of these soil parameters was estimated. Results The study revealed that during aridization in the steppe zone, there is a change in plant association, what lead to the biomass and bio-productivity of steppe decrease, and chemical elements associated with salts accumulate in soils (Ca, Mg, Na, S, Sr). The accumulation of Ca, K, Na, S, Cl by arid species leads to further degradation of the soil cover (salinization, forming of cambic horizon) and a decrease in its sustainability.Conclusions The data obtained will contribute to a better understanding of the role of plants in the sustainability of the soil cover of modern steppes, which is necessary to predict the response of landscapes to future climate changes.

Abstract
Dementia is a heterogeneous neurodegenerative condition that affects more than 50 million people worldwide and encompasses diseases such as Alzheimer’s disease, vascular dementia or Parkinson disease. It is associated with both structural and functional alterations of the brain vasculature, which are now believed to be early precursors of the diseases. Here, we investigate how functional ultrasound (fUS) imaging applied to the retina may allow to assess neurovascular alterations through neurovascular coupling in rat models. We first imaged the retinal microvascular architecture with ultrafast ultrasound localization microscopy and retrieved highly detailed maps of the microvasculature including quantitative blood velocities in main vessels. We then performed functional ultrasound trans-orbital imaging to measure light-induced retinal hemodynamic response function in vivo in the TgF344-AD rat model of Alzheimer disease compared to wild-type age-matched control rats. We showed that retinal fUS allows the robust measurement of the neurovascular response in the rat retinal vasculature and to discriminate different neurovascular responses between healthy and transgenic animals, with an average relative increase of blood volume of 21% in the WT versus 37% for the TG group (p = 0.019). rfUS could thus become a promising functional screening tool in clinics in search of pre-symptomatic biomarkers of dementia.

Published: July 2022

Abstract
Objective
Robust epidemiological and audiological data are needed to prepare for future clinical trials aiming at preventing cisplatin-induced ototoxicity in this suffering cancer population. We precisely assessed the incidence, severity and potential risk factors of symptomatic cisplatin-induced ototoxicity in a large cohort of adults.
Methods
Retrospective cohort study at a tertiary care university hospital. Study group included 401 consecutive patients over 18 years old treated with cisplatin-based chemotherapy, without concomitant inner ear radiotherapy nor other ototoxic medication. Every participant underwent baseline pre-treatment audiometry and were asked for otological symptoms (tinnitus, hearing loss). If symptomatic, comparative audiometry was performed. Ototoxicity was defined by a threshold shift ≥ 15 dB HL in at least one of the tested frequencies.
Results
A total of n = 401 cancer patients (59% males) with a mean age of 56 years (range 18–80 years). N = 81 patients (20%) developed symptomatic ototoxicity, affecting predominantly the high frequencies from 4 to 8 kHz. Among the patients with cisplatin-induced hearing loss, n = 49 (60%) experienced simultaneous tinnitus, occurring in over half of them after the first cycle of chemotherapy. None of the analyzed potential risk factors age, gender, smoking, hypertension, diabetes, vasculopathy, dyslipidemia, chemotherapeutic regimen and cumulative cisplatin dose was statistically correlated with the occurrence or severity of cisplatin-induced hearing loss.
Conclusion
One out of five adult cancer patients treated with cisplatin chemotherapy developed a symptomatic and predominant high-frequency hearing loss, with simultaneous occurrence of tinnitus in over half of them. Standardized audiological monitoring before and during cisplatin chemotherapy allows to quantitatively assess early and objective signs of ototoxicity and offers to optimize anticancer therapy while minimizing morbidity in a multidisciplinary setting.

Abstract
Objective: β-thalassemia major is an inherited hemoglobin disorder resulting in chronic hemolytic anemia. Cardiac involvement is the main cause of death in patients. Speckle-tracking echocardiography is feasible method for the evaluation of cardiac function via an assessment of the longitudinal deformation of the myocardium through the cardiac cycle. The aim of our study is to evaluate the association of vitamin D deficiency and deformation of the left ventricular myocardium measured by speckle-tracking echocardiography in children with thalassemia major.Methods: In this prospective study, 33 thalassemic patients with vitamin D deficiency were enrolled. Cardiac magnetic resonance T2* value, conventional echocardiography and speckle tracking, left ventricle longitudinal and circumferential strain values were measured. Vitamin D level <20 ng/ml deficient, 20-30 ng/ml insufficient, >30 ng/ml considered sufficient. Myocardial functions of patients with vitamin D deficiency or insufficiency were evaluated by speckle-tracking echocardiography before and after vitamin D replacement.Results: The mean age of our patients was 15.4 ± 3.09 years, male / female ratio was 18/15. Vitamin D level was deficient in 30 (90%) and insufficient in 3 (10%) of our patients. Speckle-tracking analysis showed a significantly decreased absolute value of left ventricle global longitudinal strain before vitamin D replacement. A significant improvement in the global longitudinal strain of left ventricular after vitamin D replacement was detected (p<0.05). A statistically significant increase was observed in parameters showing left ventricular systolic and diastolic functions after vitamin D replacement.Conclusion: Vitamin D deficiency are frequently observed and vitamin D deficiency causes decreased contractility and leads to an increase in cardiac iron in thalassemic patients. In our study, we observed that our patients cardiac functions had improved after vitamin D replacement therapy. Further prospective studies are needed to evaluate the relationship between vitamin D levels and cardiac function in patients with these patients.
