Low pilot overhead channel estimation for CP‐OFDM‐based massive MIMO OTFS system
Authors: Li Tong , Han Chuang , Yao Rugui , Fan Ye , Zuo Xiaoya
Published: November 2021

In high‐speed mobile scenarios, due to the high‐speed relative motion between transmitter and receiver, the high Doppler frequency shift interferes with the inter‐subcarrier orthogonality in orthogonal frequency‐division multiplexing (OFDM) systems. Therefore its performance is significantly degraded. Recently, orthogonal time–frequency space (OTFS) is considered as an effective alternative scheme to OFDM for time‐varying channels. As with OFDM‐massive multiple input multiple output (MIMO) systems, downlink channel estimation is necessary for OTFS‐massive MIMO systems to improve the spectral efficiency in frequency‐division duplex (FDD) mode without channel reciprocity. Here, first the cyclic prefix ‐OFDM‐based massive MIMO OTFS system channel with antenna directivity pattern is analyzed, and transform the burst sparsity in the angle domain into block sparsity by using non‐uniform Fourier transform (NUFT). Furthermore, to solve the problem that the pilot overhead grows linearly with the number of antennas, we propose a three‐dimensional (3D) dynamic support detect (DSD) algorithm. Compared with the traditional OMP algorithm, and the 3D‐structured orthogonal matching pursuit algorithm, simulation results demonstrate the proposed DSD algorithm has higher channel estimation accuracy, and lower pilot overhead.
Locally and globally optimal solutions of global optimisation for max‐plus linear systems
Authors: Wang Cailu , Tao Yuegang
Published: November 2021

This paper considers the locally and globally optimal solutions of the global optimisation problem whose objective function is a max‐plus vector‐valued function and constraint function is a real affine function. The formulas about global optimisation in the existing work are further explained and simplified. The necessary and sufficient conditions for the existence and uniqueness of locally optimal solutions of a single objective are established, which are then used to deduce these of globally optimal solutions. Furthermore, the general formulas of locally and globally optimal solutions are presented, respectively. The local optimisation is then applied to solve the load distribution problem of distributed systems with no globally optimal solution, and the optimal allocation scheme is proposed to complete the overall task at the earliest time. The proposed method is constructive, and the obtained results are illustrated by the numerical examples.
Load component decomposition and online modelling based on small disturbance response characteristic matching
Authors: Zeng Yuan , Meng Dezhuang , Liu Bo , Hu Xinyuan , Luan Wenpeng
Published: November 2021

Accurate load model significantly influences the numerical simulations of power system. The load model obtained by the component‐based method does not adequately reflect the load time‐varying characteristics, and the measurement‐based method relies on fault data, but system faults rarely occur. Inspired by the theory of non‐intrusive load monitoring, the load component decomposition and online modelling method based on the small disturbance response characteristic matching is proposed. An optimization model for the load component decomposition based on the curve fitting of small disturbance response characteristics is established. The construction method of a typical load model library is given and a neural network‐based solution is designed. The proposed method can determine the load components that constitute the synthesis load model and their proportions by only analysing the small disturbance real‐time measurement data. To verify the effectiveness of the proposed method, the distribution of the decomposition errors was analysed by the Monte Carlo simulation. Furthermore, the accuracy of the synthesis load model was verified by a fault simulation using the CEPRI 36‐node system. Experimental results show that the proposed method can provide accurate load compositions and dynamically update the synthesis load model for the online power system simulation, planning and operation.
Improving step‐up gain and efficiency in non‐inverting buck‐boost dc‐dc converter using quasi‐Z impedance network
Authors: Lahooti Eshkevari Alireza , Mosallanejad Ali , Sepasian Mohammadsadegh
Published: November 2021

In conventional non‐inverting buck‐boost converters (BBC), step‐up conversion requires high duty cycles, unlike the step‐down conversion. This problem decreases the BBC efficiency in the step‐up mode. Here, an improved non‐inverting BBC is proposed, designed based on a quasi‐Z impedance network. In this topology, the step‐up conversion is done with a higher boost factor and lower duty cycles. By reducing the step‐up duty cycle, the efficiency has been increased. In this BBC, the voltage‐stress on power semiconductors is the same as the conventional type; however, the efficiency improves as power switches operate with lower duty cycles. This article presents the operating principle of the proposed topology in detail. This new topology is compared with previous topologies regarding efficiency, components, voltage, and current stresses on semiconductors, boost‐factor, and implementation cost. Sensitivity analysis results are shown to obtain the effect of the parasitic elements on the converter operation. Simulation and experimental results are also presented to evaluate the topology and its operation. Results confirm the proposed topology. This converter can be used in photovoltaic (PV) based systems like PV‐based electric vehicle (EV) charging systems.
Effects of roughness and size ratio on alumina fluid deposition patterns
Authors: Liu Bin , Liu Yue , Chai Lin
Published: November 2021

In this paper, the deposition patterns of alumina nanofluids with different particle size ratios (10 nm:30 nm = 0:1, 1:9, 3:7, 5:5 and 1:0) evaporated on different roughness (0.1, 0.15 and 0.2μm) substrates were studied. It was found that the surface roughness of substrates and particle size ratio in solution were important factors affecting the height of deposition rings and the morphology of deposition patterns. A dimensionless criterion number Ajw was defined to represent the deposition patterns. The Ajw number increases with the increase of the roughness of the floor and the proportion of small particles in the solution.
Numerical Investigation on the Electrical Performance Optimization of a Tubular Thermoelectric Generator for Waste Heat Recovery
Authors: Chen Leisheng , Yu Zuyi , Zhang Jingwen , Lee Jaeyoung
Published: November 2021

In the waste heat utilization of automobile exhaust, the tubular thermoelectric generator (TTEG) has structural advantages compared with the flat-plate thermoelectric generator. A kind of TTEG that is composed of Bi0.5Sb1.5Te3 and Ni conical rings alternately attracts researchers' attention, and it generates electrical power based on the transverse thermoelectric effect. However, the electrical performance of such TTEG still needs to be improved for industrial utilization. In this study, the performance of TTEG was optimized through numerical simulation by changing its related structural parameters, including the tilt angle, the thickness of the conical ring, and the relative content of Ni. It is confirmed that the optimal tilt angle with maximum open-circuit voltage (OCV) is 27.3°; on this basis, it is found that a thinner thickness corresponds to a larger OCV; furthermore, when using a conical rings’ thickness of 0.75 mm and increasing the relative content of Ni in the Bi0.5Sb1.5Te3/Ni layered pair from 10% to 90%, the OCV decreases from 198mV to 105mV while the power density increases from 413W/m2 to 1350W/m2. It is believed that these findings can help to develop TTEGs with better electrical performance.
Contribution to the Parametric Study of the Performance of A Parabolic Trough Collector
Authors: Bouali Belkacem , Regue Hanane-Maria
Published: November 2021

This paper presents an analysis of the performance of a parabolic trough collector (PTC) according to some key operating parameters. The effects of the secondary reflector, the length and thickness of the absorber tube (receiver tube) and the flow rate of the heat transfer fluid (HTF) are investigated. The main objective is to determine an optimal operation, which improves the performance of a traditional PTC. The target variables are the temperature at the outlet of the tube, the amount of energy collected by the HTF and the efficiency of the system. The solar flux data concern the city of LAGHOUAT located in the south of Algeria. Four days in different seasons are considered. The optical analysis of the system is performed
by using the open source SolTrace code. The output of this analysis is used as a boundary condition for the CFD solver. The conjugate heat transfer and the fluid flow through the absorber tube are simulated by using ANSYS-CFX solver. Water is considered as heat transfer fluids. The obtained results show that the use of a curved secondary reflector significantly improves the performance of the traditional PTC. As the thickness of the tube increases, the heat storage in the material increases, which increases the temperature at the exit of the tube and therefore the efficiency of the system. However, the length of the tube depends on the mass flow of the HTF and vice versa. To keep the efficiency constant by choosing another length, it is necessary
to choose a mass flow rate proportional to the flow rate corresponding to the initial length.

Authors: Özdemir Tanılay , Ekici Özgür , Köksal Murat
Published: November 2021

In this study, an electrochemical-thermal coupled model was developed to investigate the electrical and thermal behaviors of the commercial NCR18650b Li-ion cell during three different discharge rates. The 1-dimensional electrochemical model consists of a positive electrode, electrolyte, and a negative electrode and employs the related mass and charge transfer equations for both solid and liquid phases predicting the cell's voltage variation. The 3-dimensional thermal model involves a mandrel, an active battery part, and a shell. The thermal model solves the general heat diffusion equation and predicts the temperature variation of the cell. The results show that the predicted temperature-voltage profiles follow the same trend with experimental data and are consistent. The maximum calculated root mean square errors are obtained as 0.11 V for voltage, and 0.96 °C for temperature predictions. On the other hand, the maximum temperature differences within the cell was found to be 0.16 °C, 0.43 °C, and 1.29 °C after the 0.5 C, 1C and 1.5 C rate discharging processes, respectively. Finally, the results from the 3-dimensional thermal model reveal that the type of mandrel affects the temperature variation within the cell. However, the average surface temperature of the cell remains comparable for the investigated C rates.

Fakfak and Kumawa Mountains are located in Bomberay Peninsula, Papua, a poorly known ichthyological record and was recommended by Conservation International for field inventory. This research was conducted from 6-15 February 2021 to document freshwater fish diversity in northern and eastern Fakfak toward Bomberay District. The fish was collected from creeks, streams, and rivers. The fish collection was done once in each location, mainly using a seine net, while a gill net was used in a few sites along Ubadari River. It was done for four hours, netting in one to three locations each day. Fish abundance was described based on common (C), occasionally (O), dan rare (R) scales. Freshwater fish data were descriptively identified. Twenty-two native New Guinean species belonging to 19 genera and 14 families were collected during the survey. There was no specific family dominant in the fish community. All fish recorded have widespread distribution, yet only one species has restricted distribution in the Vogelkop and Bomberay Peninsulas. One rainbowfish species was observed but not properly identified. This results as initial data of the fish community of Bomberay Peninsula, especially of Fakfak. Further research is needed to reveal the fish community from another part of the peninsula.

Published: November 2021

In this study, the effects of unsaturated and saturated branchedchain fatty acids in biomembranes of microorganisms living under high temperature and high pressure on the fluidity of biomembranes were investigated by time-resolved fluorescence anisotropy measurements. First, the relationship between the order parameter S and the rotational diffusion coefficient Dw, which can be calculated from the fluorescence anisotropy measurements, and the motion of lipid molecules was investigated using lipids with three different structures, and it was found that the former was related to the spacing of lipid molecules and the latter to the motion of lipid molecules. Next, we investigated the S and Dw values of lipid bilayer membrane containing the saturated branched-chain fatty acid 12-methyltridecanoic acid (12-MTA) and the polyunsaturated fatty acid (PUFA) cis-4,7,10,13,16,19-docosahexaenoic acid (DHA). The results showed that 12-MTA increased the S value and decreased the Dw value. On the other hand, DHA tended to reduce the S value and increase the Dw value, albeit slightly. These results mean that 12-MTA narrows the molecular spacing of lipids and inhibits lipid molecular movement, while DHA tends to widen the molecular spacing of lipids and promote lipid molecular movement.

Published: November 2021

Cadmium is a metal that has high toxic effects in high and low concentrations. The presence of cadmium will adversely affect the biological processes of aquatic organisms, mainly carp, which can threaten the sustainability of their lives, including humans, through the food network. Lau Kawar Lake was formed several thousand years ago when lava flowed from the Sinabung volcano and covered the Tupin River. This study aims to analyze the level of cadmium in carp organs at Lau Kawar Lake, Karo Regency, North Sumatra. The samples were taken by purposive sampling three times. Metal tests were conducted by using the Atomic Absorption Spectrometry Method. The data were analyzed through the F—test using one-way ANOVA at a 95% confidence interval. The test results showed that the highest and lowest average cadmium levels were found in the kidneys and liver. The statistical data analysis obtained that the average Cd levels in each sample were not significantly different in the gills, kidneys, liver, and muscles. The results showed that cadmium was detected in organs of carp but was still in low levels because it had not passed the quality standard limit set by the FDR New Zealand, FAO, and FDA RI Regulations.

Published: November 2021

Disease outbreaks and mortality in giant gourami and Asian catfish (pangasius) culture have been frequently reported during the last decade. Etiological agents of the disease have remained unknown, so it is needed to explore epidemiological studies to know the main causative agents. The study aimed to know the main pathogenic agents who were identified during disease outbreaks on giant gourami and pangasius. Data and information were collected through active and passive surveillance at the production centers of each species. Analysis was carried out according to standard fish disease diagnosis and eventually was focused on two suspected new emerging diseases (NED), namely Infectious Spleen and Kidney Necrosis Virus (ISKNV) belonging to Megalocytivirus on giant gourami and Enteric Septicemia of Catfish (ESC) caused byEdwardsiella ictalurion pangasius. The results showed that ISKNV was detected on most of the diseased giant gourami samples andthat E. ictaluri was identified on mostdiseased pangasius samples. This study concluded that both pathogenic agents, Megalocytivirus andE. ictaluriwere suspected to be potentially NED on freshwater aquaculture, especially infecting giant gourami and pangasius respectively.

Growth and reproduction performance of sea cucumber (Stichopus sp.) fed with different feeding regimes. This study aims to know the effects of different feeding regimes on sea cucumbers' growth and gonad development. Sea cucumbers used in this experiment were collected from the natural habitat in Northern Bali waters. Five individuals of sea cucumber (BW 334 ± 58 g; TL 22,5± 3,5 cm) were placed in each of four concrete tanks size 0,85 x 2 x 0,5 m3 with flow-through water systems. There were two feeding treatments in this study: A) fresh benthos and B) a combination of fresh benthos and seaweed (Ulva and Sargassum). Feed was given as much as 2.5 to 5 %, once in the afternoon. Observed variables were the growth and gonad stage and the weight at the end of the experiment. The study showed that the different feeding regimes significantly influenced the sea cucumber growth and gonad weight, but not the gonad stage. Sea cucumber fed with a combination of benthos and seaweed performed better growth and higher gonad weight. The difference in the feed did not affect gonad development.

Published: November 2021

Selection programs applied to fish commodities can be done through some structured stages. The grading process is one of the critical stages of the selection program. Grading can be done by selecting a group of fish in a population that has the best growth performance. Fish groups that selection criteria for the next are maintained populations. The purpose of the study was to determine the effectiveness of grading on the growth of the gourami. This research conducted strains of giant 1gourami Jambi, Kalimantan, Majalengka, and Tasikmalaya strains.The first grading with fish body weight criteria was carried out by the time the gourami population was 11 months old, so it was obtained sub population in three sizes. Each strain is then nurtured separately. After each population months-old gourami, each individual was tagged, then maintained communally until 25 months old. Results of the experiment suggest that grading is apparently effective in affecting giant gourami growth significantly differences (P< 0.05). The implications of this research can be applied in the huge gourami selection program to produce superior strain.

Recently, a global increase in temperature has been considered with a temperature rise. Therefore, new species and diseases are getting domestic in Europe. Particularly, tilapia is kept in "colder" areas like in European waters in indoor facilities. It was examined if the tilapia lake virus (TiLV) can infect native European fish. Common carp, crucian carp, and rainbow trout were chosen to be with infected tilapia. While tilapia were infected, the other species were always cohabitated. After keeping all species together, samples were collected. Tilapia and crucian carp at 20 °C as well as rainbow trout at 12°C, showed mortality. Besides necrosis, infiltrations and syncytia were observed. TiLV was detected by in-situ hybridization in all species. Sera were used for SNT to prove the replication. While tilapia developed neutralizing antibodies after 14 to 21 dpi, carp and rainbow trout started after 12 dpi. The highest neutralizing activities we found in sera from crucian carp. All fish (tilapia, crucian carp, and rainbow trout) that died during the experiment were inspected for the presence of TiLV by RT-qPCR, histology, and ISH. Due to the experience that clinically infected fish showing severe symptoms are not producing antibodies, serology was not carried out.

Published: November 2021

Microbial diversity within an aquatic community can be used to increase the growth and development of organisms. In this study, Zebrafish larvae were reared in three treatments 1) a probiotic containing 17 strains of Lactobacillus spp., 2) an amoxicillin solution, 3) water from the broodstock culture tank as the control. Survival of the larvae throughout 10 dpf was recorded. To determine the development of the gastrointestinal tract DASPEI stain was used for larvae at the age of 3 dpf to 6dpf. The intensity of the fluorescence in each larva was observed through the automated digital microscope. According to the experiment results, a significant difference (P<0.0001) in the survival rates among all treatments was recorded. The probiotic-treated larvae (PTL) had a higher survival rate. This could be due to the presence of lactic acid bacteria in the probiotic treatment, which helps in enhancing immunity. In DASPEI staining, also PTL exhibits more fluorescence in the GI tract at 24 hours to 48 hours post-hatch than the other two treatments. The main possible reason behind this could also be the presence of Lactobacillus spp. Which directly influences the higher activity of the digestive system.

The incidence of the Covid-19 pandemic indirectly affects the decline in the activity of the processing industry and fish consumption by the community. In the short term, there is also a decline in fish prices. This study examines whether the decline in economic activity in the fisheries sector causes changes in the performance of small-scale fisheries, both before and during the Covid-19 pandemic in Tolitoli Regency, Central Sulawesi Province. The target of the research object is fishers who use trolling lines, handline, and beach seine. The analytical method used is Exponential Comparison Method. The results showed that capture fisheries belonging to SSF, which had high performance before covid-19, were fishing gear, and the lowest performance was Surrounding net. On the other hand, the surrounding net has a higher performance during the pandemic than the other three fishing gears, and the lowest is Trolling lines. However, there has been a significant decline in prices and market affordability, the economic contribution of small-scale fishing businesses from before and during the COVID-19 pandemic. For this reason, a policy to open up an export-oriented fish catch market and a wider market reach is required.

A. bicolor bicoloris a tropical eel subspecies that dominate catches in the coastal areas of West Java, and its conservation status is near threatened. Cikaso River, West Java, becomes eel migration path, while unfortunately, information concerning the stock of eel in this river is still inadequate. The objective of this study was to determine the population structure (size distribution, length-weight relationship, and condition factor) ofA. bicolor bicolorin the Cikaso River. The research was carried out in the main streams of the Cikaso River and the coastal marsh of Ciroyom from January to December 2020. Eel samples were collected using lift-net, fishhook, and traps. The number of eels caught is counted, then the total length and weight are measured. We collected nine elvers and 89 yellow eels, but no silver eel was caught during the study. The elver's total length (TL) ranged from 10.2 to 20 cm, and the TL of yellow eel ranged from 20.1 to 42.2 cm. The catch of eel is dominated by the size of 25-30 cm. The growth pattern of eel in the Cikaso River is positive allometric, with the condition factor of eel ranging from 0.450 to 1.917 (1.160±0.3096).

Published: November 2021

The demand for fresh catfish in Bogor Regency is very high, causing catfish farmers to take this business opportunity to produce more catfish. Feed contributes about 60% of operational cost, therefore to reduce the production cost, the farmer uses black soldier fly (maggot) as a supplementary feed for their catfish cultured. This research aims to analyze the business of catfish cultivation using maggot at fish-farmers group TPS3R Kayumanis in Bogor, West Java, Indonesia. The research was conducted from March to April 2021 using observation, interviews, and documentation. The business feasibility of catfish cultivation was done by calculating the revenue cost ratio (R/C), breakeven point (BEP), and return on investment (ROI). The result showed R/C ratio was 1.4; BEP was 361,437 IDR, and ROI was 8.6%. These results indicated that catfish cultivation using maggot as supplementary feed is a feasible catfish business.

Contexte :Les programmes de la santé innovent pour bonifier l’enseignement des réalités autochtones aux étudiants allochtones. Il n’existe toutefois pas d’échelle validée en français pour évaluer l’effet de ces interventions sur les préjugés à l’égard des autochtones.But :Cet article présente le processus de traduction en français et une évaluation psychométrique préliminaire desOld-FashionedetModern Prejudiced Attitudes Toward Aboriginals Scales(O-PATAS et M-PATAS).Méthodes :Trente étudiants en médecine ont complété les versions originales (VO) et traduites (VF) et 78 étudiants additionnels ont complété la VF. L’alpha (α) de Cronbach et l’oméga (ω) de McDonald ont servi à évaluer la fidélité des scores des échelles. La validité concomitante a été testée à l’aide de corrélations intra-classes et de test-t pairés. La validité de construit a été explorée à l’aide d’une analyse factorielle à deux facteurs.Résultats :La fidélité des échelles VF est acceptable et comparable à celle trouvée dans les VO (α ≥ 0,81, ω ≥ 0,85). La validité concomitante des VF est soutenue par l’absence de différence entre les scores en VO et en VF (p ≥ 0,2) et la forte corrélation intra-classe entre les scores (r ≥ 0,80,p < 0,001). Le modèle d’analyse factorielle n’a pas reproduit la structure attendue, probablement à cause du manque de puissance de l’étude.Conclusion :Cette étude présente une VF des échelles M-PATAS et O-PATAS ayant des propriétés psychométriques préliminaires comparables aux échelles dans leur VO. L’utilisation à plus grande échelle de ces outils permettra d’évaluer leurs dimensionnalités en contexte francophone canadien.
Manufacturer’s cooperation strategy of closed-loop supply chain considering corporate social responsibility

Published: November 2021

Corporate social responsibility (CSR) has become a popular and important strategy for corporate operation and sustainable development. Meanwhile, many social or environmental incidents that occur in one enterprise could bring huge risk or disruption for the entire supply chain. This study discusses the manufacturer’s cooperation strategy of closed-loop supply chain (CLSC) composed of a dominant manufacturer with CSR behavior consciousness, a retailer with CSR investment, and a third-party recycler. In the CSR-CLSC, the manufacturer exhibits CSR behavior consciousness through considering stakeholders welfare, the retailer makes CSR investment through profit donation and the third-party recycler exhibits CSR activity through product recycling. And under the Stackelberg Game setting, we formulate four different decision-making models to investigate the interaction between manufacturer’s CSR behavior consciousness and retailer’s CSR investment, as well as their impact on the manufacturer’s cooperative strategy selection and CLSC operation. The results show that both the CSR behavior consciousness of manufacturer and CSR investment of retailer are conducive to reducing the wholesale price of new products, enhancing the recycling rate of waste products and improving the performance of CSR-CLSC members, and both of them have the function of mutual incentives. The vertical cooperation strategy of manufacturer is conducive to increasing the overall performance of CSR-CLSC, and compared with the cooperation with the third-party recycler, the manufacturer has stronger motivation to cooperate with the retailer, and it is also more beneficial to improving the CSR investment level, the waste product recycling rate, and the performance of CSR-CLSC members.

Empfehlungen für Inhalt und Gestaltung von web-basierten Informationen
zur COVID-19-Impfung

Für den Erfolg der COVID-19-Impfstrategie ist eine hohe Impfbereitschaft der
Bevölkerung notwendig. Ergebnisse der „COVID-19
Impfquoten-Monitoring in Deutschland“ (COVIMO)-Studie des Robert
Koch-Instituts (RKI) zeigen jedoch auf, dass sich 20,6% der ungeimpften
Befragten „unentschlossen“ gegenüber COVID-19-Impfungen
äußerten und sich 24,3% der Befragten „auf keinen
Fall“ impfen lassen wollen (Stand August 2021) 1. Zur Suche nach Gesundheitsinformationen wird in Deutschland
häufig das Internet genutzt 2. Daher
haben die Internetauftritte zentraler Gesundheitsinstitutionen die wichtige
Funktion, zur Information der Bevölkerung hinsichtlich der
COVID-19-Impfungen beizutragen.

Objectives Pain management remains a point of emphasis given the ongoing opioid crisis. There are no studies in the literature interrogating opioid prescribing and use following endoscopic pituitary surgery. This study investigates provider prescribing tendency, patient utilization of analgesics, and patient outcomes regarding pain management after endoscopic pituitary surgery.

Methods We identified 100 patients undergoing endoscopic pituitary surgery at one institution from 2016 to 2018 in the electronic medical record (EMR) and state narcotic database to determine postoperative analgesic regimens. A telephone survey was used to characterize postoperative analgesic use and satisfaction with prescribed regimen.

Results Fifty-two different pain control regimens were prescribed to the study patients. Also, 93% of study patients were prescribed an opioid postoperatively. The average quantity of opioids prescribed per patient in morphine milligram equivalents (MMEs) was 625 (equivalent 83 oxycodone 5-mg tablets) with an average MME/day of 59 (equivalent 8 oxycodone 5-mg tablets). A total of 71% survey respondents who used opioids reported using <25% of their prescription. The majority of prescription narcotic users consumed >50% of their postoperative opioid intake in the first 24 to 48 hours after discharge. There were no significant differences in pain outcome between opioid users and nonopioid users.

Conclusion Vast heterogeneity exists in narcotic prescribing by providers at our institution following endoscopic pituitary surgery. Narcotic prescribing patterns exceeded most patients' analgesic needs. Opioid analgesics were not superior to nonopioids regimens in patient-reported pain outcomes in this study population.

Não é comum encontrar malformações arteriovenosas (MAV) durante a artroplastia total do quadril (ATQ). Relatamos o presente caso para chamar a atenção para a possibilidade de uma MAV durante a abordagem anterior direta (AAD) para ATQ, que se não for considerada, pode levar a uma miríade de complicações relacionadas ao sangramento excessivo. Uma mulher de 81 anos foi apresentada ao pronto-socorro com fratura no pescoço do fêmur esquerdo. Ela optou por se submeter a uma artroplastia total do quadril (ATQ) através da AAD. Vasos sanguíneos aparentemente anormais estavam presentes perto dos ramos circunflexos ascendentes, proporcionando dificuldade em alcançar hemostasia. A perda excessiva de sangue foi notada e a paciente recebeu uma unidade de glóbulos vermelhos embalados durante a operação. Hemoglobina e hematócrito caíram nos dias seguintes à cirurgia, exigindo várias transfusões adicionais de produtos sanguíneos. Quando a paciente reclamou de inchaço progressivo na perna esquerda no terceiro dia pós-operatório, a tomografia computadorizada revelou hematomas grandes dentro dos adutores esquerdos e do músculo iliopsoas esquerdo. A extravasão ativa foi identificada a partir de um ramo da artéria femoral esquerda, bem como de uma fístula arteriovenosa (FAV) nesta área. O sangramento foi controlado por embolização seletiva da bobina endovascular. A partir do conhecimento atual, esta é a primeira descoberta intraoperatória relatada de MAC congênita com desenvolvimento subsequente de FAV pós-operatória e hematomas sintomáticos associados no cenário de ATQ utilizando a AAD. O reconhecimento precoce e a intervenção de malformações vasculares são essenciais para prevenir possíveis complicações cirúrgicas de membros ou de risco de vida.
