Published: September 2021

Background: The practice of bariatric surgery was studied using the German Bariatric Surgery Registry (GBSR). The focus of the study was to evaluate whether revision surgery One-Step (OS) or Two-Step (TS) sleeve gastrectomy (SG) has a large benefit in terms of perioperative risk in patients after failed Adjustable Gastric Banding (AGB).Methods: The data collection includes patients who underwent One-Step SG (OS-SG) or Two-Step SG (TS-SG) as revision surgery after AGB and primary SG (P-SG) between 2005 and 2019. Outcome criteria were perioperative complications, comorbidities, 30-day mortality, and operating time.Results: The study analyzed data from 27,346 patients after P-SG, 320 after OS-SG, and 168 after TS-SG. Regarding the intraoperative complication, there was a significant difference in favor of P-SG and TS-SG compared to OS-SG (p &lt; 0.001). The incidence of pulmonary complications was significantly higher in the OS-SG (p &lt; 0.001). There was also a significant difference in occurrence of staple line stenosis in favor of TS-SG (p = 0.005) and the occurrence of sepsis (p = 0.008). The mean operating time was statistically longer in the TS-SG group than in the OS-SG group (p &lt; 0.001). The 30-day mortality was not significantly different between the three groups (p = 0.727).Conclusion: In general, our study shows that converting a gastric band to a SG is safe and feasible. However, lower complications were obtained with TS-SG compared to OS-SG. Despite acceptable complication and mortality rates of both procedures, we cannot recommend any surgical method as a standard procedure. Proper patient selection is crucial to avoid possible adverse effects.

Published: September 2021

Background: Radioactive 131I (RAI) therapy is used in patients with differentiated thyroid cancer (DTC) after total thyroidectomy for remnant ablation, adjuvant treatment or treatment of persistent disease. 131I retention data, which are used to indicate the time at which a 131I treated DTC patient can be released from the hospital, may bring some insights regarding clinical factors that prolong the length of hospitalization. The aim of this study was to investigate the 131I whole-body retention in DTC patients during 131I therapy. Methods: We monitored 166 DTC patients to follow the 131I whole-body retention during 131I therapy with a radioactivity detector fixed on the ceiling of each protected room. A linear regression fit permitted us to estimate the whole-body 131I effective half-life in each patient, and a relationship was sought between patients’ clinical characteristics and whole-body effective 131I half-life. Results: The effective 131I half-life ranged from 4.08 to 56.4 h. At multivariable analysis, longer effective 131I half-life was related to older age and extensive extra-thyroid disease. Conclusions: 131I effective half-life during 131I treatment in DTC patients is highly variable among patients and is significantly longer in older and in patients with RAI uptake in large thyroid remnants or in extrathyroidal disease that significantly prolongs the whole-body retention of 131I.

The global prevalence of diabetes mellitus (DM) has reached 20%. Air pollutants with a particle size of less than 2.5 μm (PM2.5) are a globally recognized risk factor for diabetes and glaucoma. We examined whether the risk of glaucoma would decrease or increase when patients with DM were exposed to different PM2.5 concentrations. Data were obtained from the National Health Insurance Research Database (NHIRD) of Taiwan and the Air Quality Monitoring Network between 2008 and 2013. This nested case–control study involved 197 DM patients with glaucoma and 788 DM patients without glaucoma. Cases and controls were matched (1:4) by gender, age (±5 years), and index date (±6 months), and their data were entered in a logistic regression model adjusted for gender, age, urbanization level, income level, and comorbidities. The odds ratio (OR) of glaucoma at PM2.5 exposure concentration in the fourth quartile (Q4) compared with in the first quartile (Q1) was 1.7 (95% CI: 1.084–2.764). For glaucoma risk, the OR was 1.013 (95% CI: 1.006–1.020) at a PM2.5 exposure concentration in Q1, 1.004 (95% CI: 1.001–1.007) in the third quartile (Q3), and 1.003 (95% CI: 1.001–1.004) in Q4. In the subgroup analysis of patients living in non-emerging towns and non-agricultural towns, the OR for glaucoma in Q4 compared with in Q1 was 2.1 (95% CI: 1.229–3.406) and 1.8 (95% CI: 1.091–2.803), respectively (p trend = 0.001 and 0.011). For patients without migraine, the OR for glaucoma was 1.7 (95% CI: 1.074–2.782; p = 0.006). These results demonstrate that, for patients with DM, PM2.5 increased the risk of glaucoma and PM2.5 was an independent risk factor for glaucoma in patients with DM.
Deep Learning for Chlorophyll-a Concentration Retrieval: A Case Study for the Pearl River Estuary
Authors: Ye Haibin , Tang Shilin , Yang Chaoyu 
Published: September 2021

The abundance of phytoplankton is generally estimated by measuring the chlorophyll-a concentration (Cchla), which is an important factor in photosynthesis and can be used to analyze the density and biomass of phytoplankton in the ecosystem. The band-ratio-based empirical or semi-analytical algorithms are operationally applied to retrieve Cchla in global oceans, which generally experience difficulties from the diversity of optical properties and the complexity of the radiative transfer equations in analytical analyses, respectively. With an attempt to develop an accurate Cchla retrieval model for the optically complex coastal and estuarine waters, this study aimed to explore the deep learning (DL) methods in satellite retrieval of Cchla. A two-stage convolutional neural network (CNN), named Cchla-Net, was proposed, which utilized the spectral information of remote sensing reflectances at MODIS/Aqua’s visible bands. In the first-stage phase, the Cchla-Net was pretrained by a set of remote sensing patches, in which the Cchla was generated from an existing model (OC3M). The pretrained results were than used as the initial values to refine the network with the synthetic oversampled in-situ dataset in the second-stage training phase. Using in-situ samples for training with the new initial values has a higher probability to reach the global optimum. The quantitative analyses showed that the two-stage training was more likely to achieve a global optimum in the optimization than the one-stage training. Matchups of the in-situ Cchla measurements were used to evaluate the retrieval models. Results showed that the proposed Cchla-Net produced obvious better performance than the empirical and semi-analytical algorithms, implying the DL method was more effective for optically complex waters with extremely high Cchla. This study provided an applicable method for remote sensing retrieval of Cchla, which should be helpful for studying the spatial distribution and temporal variability in the productive Pearl River estuary (PRE) waters.

The Yanqi basin is the main irrigated and active agroecosystem in semi-arid Xinjiang, northwestern China, which further seeks responses to the profound local water-related drawbacks in relation to the unceasing landscape desiccation and scant precipitation. Yet, it comes as an astonishment that a few reported near-surface items and water vapor fluxes as so far required for water resources decision support, particularly in a scarce observation data region. As a contributive effort, here we adjusted the sensible heat flux (H) calibration mechanism of Surface Energy Balance Algorithm for Land (SEBAL) to high-resolution satellite dataset coupled with in-situ observation, through a wise guided “anchor” pixel assortment from surface reflectance-α, Leaf area index-LAI, vegetation index-NDVI, and surface temperature (Pcold, Phot) to model the robustness of energy fluxes and Evapotranspiration-ETa over the basin. Results reasonably reflected ETa which returned low RMSE (0.6 mm d−1), MAE (0.48 mm d−1) compared to in-situ recordings, indicating the competence of SEBAL to predict vapor fluxes in this region. The adjustment unveiled the estimates of the land-use contribution to evapotranspiration with an average ranging from 3 to 4.69 mm d−1, reaching a maximum of 5.5 mm d−1. Furthermore, findings showed a high striking energy dissipation (LE/Rn) across grasslands and wetlands. The vegetated surfaces with a great evaporative fraction were associated with the highest LE/Rn (70–90%), and water bodies varying between 20% and 60%, while the desert ecosystem dissipated the least energy with a low evaporative fraction. Still, besides high portrayed evaporation in water, grasslands and wetlands varied interchangeably in accounting for the highest ETa followed by cropland. Finally, a substantial nexus between available energy (Rn-G) and ETa informed the available energy, influenced by NDVI to be the primary driver of these oases’ transpiration. This study provides essentials of near-surface energy fluxes and the likelihood of ETa with considerable baseline inferences for Yanqi that may be beneficial for long-term investigations that will attend in agrometeorological services and sustainable management of water resources in semi-arid regions.

Authors: Wang Heng , Xu Tiandong , Li Feng 
Published: September 2021

Subway station emergencies have caused serious casualties in recent years, so the aim of this research was to develop and establish an evacuation model that considers the OCEAN personality psychological traits to improve the credibility of the emergency pedestrian evacuation simulation. Firstly, the relationship between the personality and psychological stress was established based on the reconstruction of a passenger’s personality traits. Secondly, the relationship between the expected speed and a passenger’s personality traits was modified based on the social force model. Finally, the simulation was carried out using the Anylogic software. The results show that as the value of the personality increases, the evacuation time of personalities ψA and ψC gradually increases, but the opposite effect is observed for personalities ψN and ψE. Similarly, as the value of personality traits increases, the speed of personalities ψA and ψC gradually decreases, but the opposite effect is observed for personalities ψN and ψE. Only during peak periods, as the value of personality traits increases, the density of the connecting area of passengers with personality traits ψA and ψC gradually increases; on the contrary, that of passengers with personality traits ψN and ψE gradually decreases. The conclusion of this study is that different personality traits have different effects on evacuation behavior, which enriches the model of pedestrian evacuation further.

Authors: Rodrigues Gislene , Silva Helga Cristina Almeida da 
Published: September 2021

Introdução. Hipertermia Maligna (HM) é doença farmacogenética, desencadeada pela exposição de indivíduos susceptíveis a anestésicos voláteis e succinilcolina. Excepcionalmente, crises são desencadeadas por exercício e calor ambiental. Esse estado hipermetabólico manifesta-se por hipercapnia, taquicardia, rigidez muscular, acidose lática e hipertermia; sem tratamento específico, mortalidade alcança 70-80%. Fora da crise, geralmente o paciente é assintomático, mas raramente apresenta intolerância ao esforço, cãibras musculares ou sinais de miopatia. Artigos/livros e sites informam profissionais de saúde e leigos sobre diagnóstico de HM com teste de contratura muscular in vitro e genética, além do tratamento da crise de HM com dantrolene, mas não estão disponíveis informações para período intercrítico. Objetivo. Elaboração de manual de orientações para os susceptíveis à HM, quanto aos cuidados na vida diária. Método. O manual de orientações fundamentou-se em revisão bibliográfica sobre repercussões da susceptibilidade à HM, realizada segundo diretrizes do QUORUM e do Grupo de Trabalho de Medicina Baseada em Evidências. Resultados. A revisão localizou 129 artigos que foram analisados e permitiram a elaboração de 14 perguntas relacionadas a cuidados com exercício, diagnóstico pré-natal, manejo de doenças associadas pré-existentes (diabetes mellitus, asma brônquica), intoxicações exógenas, drogas ilícitas, tratamento odontológico, e medicações (serotoninérgico, quinolona, anti-dislipidêmico, contraste iodado, inibidor de fosfodiesterase III, bloqueador de canal de cálcio, betabloqueador, neuroléptico, heparina). As informações foram vertidas para linguagem leiga e usadas no manual de orientação disponibilizado online (www.cedhima.unifeps.br). Conclusão. Apesar da HM ser conhecida pela crise anestésica, há implicações na vida diária que devem ser divulgadas para pacientes e profissionais de saúde.

Published: September 2021

Дана постановка задачи по расчету оптимальной степени поврждения здания при сейсмическом воздействии. Условие оптимизационного расчета записано в виде вероятностно-экономической целевой функции, где начальные затраты на антисейсмическое усиление здания уравновешиваются с вероятностыми потерями, связанными с наступлением той или иной степени повреждения здания. Вероятность безотказности здания, соответствующая данному уравновешенному состоянию, названа оптимальной надежностью, а степень повреждения - оптимальной степенью повреждения. Всего в соответствии со шкалой MSK-64 рассмотрены 5 степеней повреждения. Последовательности переходов из одних состояний повреждения в другие представлены в виде простейшего Марковского потока с непрерывным временем и дискретными состояниями. Составлены дифференциальные уравнения процесса переходов и представлены их общие решения. В случае если последствия наступленияопределенной степени повреждения здания носят как экономический, так и неэкономическией характер, предложено, исходя из зависимости расчета экономических потерь и затрат от повышения надежности до высоких уровней и показателя нормативного уровня надежности здания, определенного по предлагаемому в литературе выражению, принять решения о допустимой степени повреждения здания.
The problem statement is given for calculating the optimal degree of damage to a building under seismic impact. The condition of the optimization calculation is written in the form of a probabilistic-economic objective function, where the initial costs for antiseismic strengthening of the building are balanced with the probabilistic losses associated with the onset of one or another degree of damage to the building. The probability of a building's reliability, corresponding to a given balanced state, is called the optimal reliability, and the degree of damage is called the optimal degree of damage. In total, in accordance with the MSK-64 scale, 5 degrees of damage are considered. Sequences of transitions from one damage state to another are presented in the form of the simplest Markov flow with continuous time and discrete states. Differential equations of the transition process are compiled and their general solutions are presented. If the consequences of the onset of a certain degree of damage to the building are both economic and non-economic in nature, it is proposed, based on the dependence of the calculation of economic losses and costs from increasing reliability to high levels and the indicator of the standard level of building reliability, determined according to the expression proposed in the literature, to make decisions on permissible degree of damage to the building.

Published: September 2021

Статья посвящена теме переработки отвалов рудника Байжансай в Туркестанской области, который, в настоящее время, является местом отходов полиметаллической руды в количестве примерно 6,5 тонн. В материале рассматривается потенциальная возможность применения данных отходов для извлечения полезных компонентов, таких как из цветных металлов - свинец и цинк, из благородных серебро и из редкоземельных - германий, индий, селен, теллур и таллий. При использовании данной переработки можно не только снизить негативное влияние отходов на окружающую среду, но и добыть полиметаллические руды, которые можно использовать в производстве стекол, оптики, в производстве высокоответственных подшипников для двигателей, для защиты антикоррозионных металлопокрытий и во многих других сферах, указанных в данной статье. Авторами было изучено технологическое решение по переработке отходов Байжансая. На основании полученных данных, была разработана технологическая модель, сочетающего в одном аппарате процессы электрохимической активации воды, флокуляции, газонасыщения и разделения микропримесей редких и рассеянных элементов (РРЭ), цветных металлов из технологических растворов и жидких техногенных отходов. Данный модуль является аналогом "классического" аппарата, но преимуществом предложенного модуля является меньшая энерго затратность, более эффективная работа по временным аспектам и по габаритам.
The article is devoted to the topic of processing the dumps of the Baizhansai mine in the Turkestan region, whichis a place of waste of polymetallic ores in the amount of about 6.5 tons. The article discusses the potential use of these wastes for the extraction of useful components, such as non-ferrous metals - lead and zinc, precious silver, and rare-earth metals - germanium, indium, selenium, tellurium and thallium. With the use of this processing, it is possible not only to reduce the negative impact of waste on the environment, but also to extract polymetallic ores that can be used in the production of glass, optics, in the production of highly critical bearings for engines, to protect anti-corrosion metal coatings and in many other areas specified in this article. The authors studied the technological solution for the processing of waste from Baizhansai. Based on the data obtained, the authors of the article have developed a technological module that combines in one apparatus the processes of electrochemical activation of water, flocculation, gas saturation and separation of trace impurities of rare and trace elements (RRE), non-ferrous metals from technological solutions and liquid man-made waste. This module is analogous to the "classical" apparatus, but the advantage of the proposed module is lower energy consumption, more efficient work in terms of time and dimensions.
