Massive Periprosthetic Osteolysis Spreads to the Soft Tissue and Pelvic Region after Primary Total Hip Replacement: A Case Report
Authors: Ponomarjova Eleonora , Jakovicka Darta , Studers Peteris
Published: April 2023

Introduction: Periprosthetic osteolysis (PPOL) is a serious complication after total hip replacement and requires immediate action to prevent further spread to nearby tissues and has the opportunity to restore hip function successfully. We present the case of PPOL of a patient with a challenging course of treatment. Case Report: We report a 75-year-old patient with PPOL that spreads to the soft tissues and pelvic region 14 years after primary total hip arthroplasty. At all stages of treatment, an elevated neutrophil-dominant cell count was detected in the analysis of synovial fluid aspiration of the left hip joint without detection of microbiological culture. Due to severe bone loss and general patient condition, no further surgical treatment was indicated, and there is no clear vision of future actions. Conclusion: Management of severe PPOL can be challenging, as there are limited surgical treatment options with a good long-term prognosis. If an osteolytic process is suspected, it should be treated as soon as possible to avoid more severe progression of the complications. Keywords: Periprosthetic osteolysis, total hip replacement, bone lesion.

Authors: Previ Leonardo , Guidi Marco , Rescigno Giulia , Niccolo Riccardo Di , Marzilli Fabio , Perugia Dario
Published: April 2023

Introduction: Metatarsal stress fractures typically occur in the second and third metatarsus metaphysis, with only rare cases in the fourth and first. The main factors influencing its onset are repetitive stress from prolonged training, biomechanical factors and bone weakness. There is only a paucity of literature documenting first metatarsal stress fractures; the authors present a rare bilateral first metatarsal stress fracture. Case Report: A Caucasian 52-years-old amateur female runner with no other risk factors or medical condition was admitted in our institute with complaints of severe bilateral forefoot pain for 2 weeks arisen after a 20 km run of an amateur race. The patient presented bilateral hallux valgus (HVA) and advanced osteoarthritis of the first metatarsal-phalangeal joint, which is not usually considered a biomechanical risk factor for metatarsal stress fractures. Radiographs of both feet showed linear sclerosis, perpendicular to the diaphysis of the first metatarsal, approximatively in the half of the bone. Signs of osteoarthritis of the first metatarsal-phalangeal were also detected bilaterally. The patient was treated with rest, bilateral post-operative rocker sole shoes that she has worn for 6 weeks, cryotherapy, analgesics as needed and pulsed electromagnetic fields for 8 h per day for 40 days with a complete resolution of symptoms and the previous radiological findings. Conclusion: The authors believed that the bilateral HVA condition could be considered an indirect sign of overuse, and it may be investigated and eventually treated as a responsible for this pathologic condition. Keywords: Stress fracture, first metatarsal, pulsed electromagnetic fields.
Delayed Presentation of Sciatic Nerve Palsy Due to Post-traumatic Pseudoaneurysm Following Pelvis Fracture: A Case Report
Authors: Fried Sarah , Lipphardt Matthew , Moore Drew D.
Published: April 2023

Introduction: Pseudoaneurysms are vascular lesions occurring after injury to a blood vessel wall. Peripheral artery pseudoaneurysms as a fracture complication are uncommon and typically appear immediately after trauma or surgery. We report a unique case of sciatic nerve palsy associated with external iliac artery pseudoaneurysm arising 20 years after pelvic trauma, presenting within the fracture site as an erosive bone lesion masquerading as a possible malignancy. To the best of our knowledge, no cases of delayed external iliac artery pseudoaneurysm involving sciatic pain have been reported. Case Report: We present a 78-year-old female who sustained an acetabular fracture with an uneventful recovery for 20 years. The patient presented post-injury with symptoms and physical examination findings consistent with sciatic nerve palsy. Computed tomography angiography and duplex imaging revealed a pseudoaneurysm of the external iliac artery. The patient was taken to the operating room for endovascular repair of the external iliac artery using a covered stent. Conclusion: This case of sciatic nerve palsy is a unique contribution to the literature concerning the specific vascular injury observed and the delayed presentation of pseudoaneurysm causing sciatic nerve palsy. Orthopedic surgeons must consider a wide differential when confronted with suspicious pelvic masses. Failure to diagnose these as a vascular etiology could prove catastrophic should the surgeon attempt an open debridement or sampling. Keywords: Pseudoaneurysm, false aneurysm, sciatic nerve palsy, pelvis fracture, bone lesion.
An Uncommon Case Report: Pathologic Fracture in a Proximal Femur Aneurysmal Bone Cyst in a Child
Authors: Sonkusale Aashay , Gandhi Pratik , Jadhav Deepak , Keswani Pranav
Published: April 2023

Introduction: Aneurysmal bone cysts (ABCs) are a group of benign, expansile, locally aggressive lesion characterized by fluid-filled cysts usually in the metaphyseal end of long bones. They usually affect children and young adults, with an atypical etiology and uncommon presentation. Treatment modalities include en bloc resection and curettage with or without bone graft or bone substitute augmentation with instrumentation, sclerosing agents, arterial embolization, and adjuvant radiotherapy. Case Report: We report a rare case of ABC with pathological fracture in the proximal femur of a 13-year-old male patient, who presented to the emergency department with severe pain in the right hip and inability to walk following trivial fall while playing. Curettage with open biopsy was performed followed by implantation with modified hydroxyapatite granules and internal fixation for the subtrochanteric fracture with pediatric dynamic hip screw and four hole plate, with a favorable outcome. Conclusion: There is a lack of a standard guideline for the management on account of uniqueness of these cases; curettage with bone graft or bone substitutes in conjunction with internal fixation of associated pathologic fracture yields bony union with adequate clinical results. Keywords: Aneurysmal bone cyst, pathological fracture, proximal femur.

Published: April 2023

Introduction: Bilateral radial head fractures are a unique and rare presentation. Few studies are available in the literature documenting these type of injuries. We present a rare case of bilateral radial head fractures (Mason type 1) and managed conservatively with full functional recovery. Case Report: A 20-year-old male sustained bilateral radial head fractures (Mason type 1) following a roadside accident. The patient was managed conservatively with above elbow slab for 2 weeks followed by range of motion exercises. The patient had uneventful follow-up with full range of motion at elbow. Conclusion: Bilateral radial head fractures in a patient are a discreet clinical entity. A high index of suspicion, meticulous history, clinical examination, and appropriate imaging is essential in patients with history of fall on outstretched hands to avoid missing diagnosis. Early diagnosis, proper management, and appropriate physical rehabilitation lead to complete functional recovery. Keywords: Bilateral elbow joint, fracture dislocation, radial head fractures.

Published: April 2023

Introduction: Proximal humerus fractures account for 4–5% of the fractures in long bones with a bimodal distribution. A wide spectrum of options are available in its management ranging from conservative to total shoulder replacement. We aim to demonstrate a minimally invasive simple 6-pin technique in the management of proximal humerus fracture using Joshi external stabilization system (JESS). Case Report: We report the results of ten patients (M: F = 4:6) with proximal humerus fractures of age range between 19 and 88 years managed with the 6-pin technique JESS under regional anesthesia. Of the included patients, 4, 3, and 3 cases belonged to Neer Type II, III, and IV, respectively. On analysis of outcomes based on the Constant-Murley score, we noted excellent outcomes and good outcomes in 6 (60%), and 4 (40%) patients, respectively, at 12 months. Fixator was removed after the radiological union between 8 and 12 weeks. Complications noted include pin tract infection in 1 (10%) and malunion in 1 (10%) case. Conclusion: JESS fixation by 6-pin technique remains a viable minimally invasive cost-effective treatment option in the management of proximal humerus fractures. Keywords: JESS, proximal humerus fractures, 6-pin technique, minimally invasive, case series.
To Evaluate The Outcome of Proximal Femoral Nail A2 in Management of Inter-trochanteric Fractures of Femur in Elderly
Authors: Dinkar Karuna Shankar , Yadav Rohit , Uppal Arjun , Pal Chandra Prakash , Gupta Mayur
Published: April 2023

Introduction- The incidence of inter-trochanteric fracture in the elderly is rising because of increased age and with low bone mineral density. The presence of osteoporosis in inter-trochanteric fractures is important because the fixation of the proximal fragment depends entirely on the quality of the cancellous bone present. The surgical stabilization of inter-trochanteric fractures remains a persistent challenge. The purpose of this study is to study the effectiveness and drawbacks of one such newer intramedullary device, Proximal Femoral Nail Antirotation in the management of inter-trochanteric fractures. Material and method- Patients who underwent PFNA for inter-trochanteric fractures at a tertiary care center Agra, who have given written and informed consent. Patients fitting into inclusion criteria would form the study group. Data collected by interviews, observation of clinical and radiological findings and assessment of function done using Harris hip score. Results- The study comprised 24 patients, with a mean age of mean age 63 years who suffered fracture inter-trochanteric femur, due to either trivial fall (75%) or RTA (17%) and managed by cephalomedullary nailing using Proximal Femoral Nai Antirotation at our center. The majority of the patients had the quality of reduction; the Majority of patients took 12 to 22 weeks for union with mean union time of 14 weeks. Patients were asked to follow up routinely, with post-operative follow up ranging from a minimum of 11 months to 18 months. At the final follow up following results obtained according to Harris Hip Score, were 55% patients excellent, 30.50% patients good, 12% patients fair, 2.50% patients poor. Conclusions- The inter-trochanteric fracture in elderly patients treated with cephalomedullary nailing using proximal femoral nail-anti-rotation, which has the biomechanical advantage of the helical blade providing bone compaction, increasing surface area and better anchorage in the femoral head, which showed favorable outcome by retarding rotation and varus collapse and prevents medialization by acting as a central pillar. Keywords- Inter-trochanteric fractures; Proximal femoral nail A2; Harris Hip Score.
The happy accident: Post-anthropocentric understandings of serendipity in making processes
Authors: Ash Nigel , Thompson Stephen , Woodward Martyn
Published: April 2023

This position paper establishes a way towards a post-anthropocentric understanding of serendipity, or the happy accident, in making processes across art, craft and design. Throwing into question hylomorphic attempts to understand the application of the maker’s know-how, which devalues the enabling capabilities of the ‘happy accident’, this position paper sets a course towards a post-anthropocentric model of making. Exploring the ineffability of materials and other events or circumstances that lie outside of purposeful affordances diffracts the focus from purposeful human agency. Instead, re-understanding the maker’s process and knowledge as a transcendent intra-action between flows of material and cognition opens up space for a more subtle and comprehensive investigation into the complexity of human and non-human intra-action, which shapes the maker and the made in a reciprocal process.

Characterization of polymorphisms in the follicle-stimulating hormone receptor and insulin-like growth factor-1 genes and their association with fertility traits in Jawa-Brebes cows
Authors: Hartanto Slamet , Budiyanto Agung , Widayanti Rini , Setyawan Erif Maha Nugraha , Prasetya Imawan Daru
Published: April 2023

Background and Aim: The availability of fertility markers is crucial for maintaining, protecting, and improving the genetics of Jawa-Brebes (Jabres) cows. Follicle-stimulating hormone receptor (FSHR) and insulin-like growth factor-1 (IGF-1) play critical roles in female reproductive physiology. The single-nucleotide polymorphisms (SNPs) FSHR G-278A> and IGF-1 C-512T correlate with cows' fertility traits. This study aimed to identify these SNPs and their potential associations with fertility parameters in Jabres cows.

Materials and Methods: Samples were collected from 45 heads of multiparous Jabres cows aged 3–10 years with body condition scores of 2.5–5.0 on a 5-point scale in Brebes Regency, Java, Indonesia. These cows were assigned to fertile (n = 16) and infertile groups (n = 29). Polymerase chain reaction (PCR) was carried out for DNA amplification of FSHR G-278A and IGF-1 C-512T fragments. Restriction fragment length polymorphism-PCR with the restriction enzymes FaqI for the product of FSHR G-278A and SnaBI for the product of IGF-1 C-512T was used to identify SNPs.

Results: The FaqI enzyme cut the 211 bp DNA fragment of FSHR G-278A in all samples into two bands of 128 bp and 83 bp (GG genotype). Meanwhile, the genotyping of amplicon products of IGF-1 C-512T generated a single 249 bp fragment (CC genotype) in both groups.

Conclusion: The results showed that the FSHR G-278A/FaqI and IGF-1 C-512T/SnaBI loci were monomorphic in Jabres cows. Thus, neither FSHR G-278A/FaqI nor IGF-1 C-512T/SnaBI is a possible genetic marker for fertility in Jabres cows.

Keywords: fecundity, genetic marker, Indonesian cow, restriction fragment length polymorphism-polymerase chain reaction.

Authors:   Jordan University of Science and Technology, S. Numayr Karim , N. Ababneh Ayman , K. Almashaqbeh Hashem
Published: April 2023

A finite element (FE) method is used for modeling edge effects in composite laminates with different ply orientations. Two types of three-dimensional isoperimetric FE methods have been used. One in the interior region has standard linear shape functions, while the other in the exterior region has special shape functions for which an exponential variation is derived using the perturbation technique. The exponential shape functions are introduced to an originally written FE program which uses special mesh generation and numerical integration, as well as other subroutines. The proposed FE solution is found to be in good agreement with the solutions available in the literature.

Published: April 2023

A chitosan-polyvinyl pyrrolidone K-30 (Cs-PVP.K30) membrane was prepared as a heterogeneous catalyst supporting membrane in the transesterification process in the production of biodiesel from palm oil and methanol through the blend reaction between chitosan (Cs) and polyvinyl pyrrolidone K-30 polymer (PVP K-30). Several membranes were characterized by their physicochemical and catalytic properties. Based on physicochemical data, it was found that including the carbonyl group from PVP K-30 into the chitosan framework correlated with an increase in porosity, hydrophilicity, water absorption, and the degree of swelling of the membrane. The results of the analysis using Fourier Transmittance Infra-red (FTIR) showed the spectra of carbonyl (-C=O) and hydroxyl (-OH) groups at wavenumbers 1648 cm-1 and 3363 cm-1, which shows that the reaction of chitosan alloy with PVP K-30 has been successfully carried out. The catalytic site of the Cs-PVP K30-NaOH membrane in the biodiesel production process was studied under several conversion conditions. It was found that the conversion of biodiesel reached 93.90% with a reaction time of 90 minutes, a temperature of 65°C, and an oil/methanol mole ratio of 1:7.

Published: April 2023

Hepatocellular carcinoma (HCC), or liver cancer, is the fourth largest cancer in Indonesia, with 21,392 new cases and around 20,920 deaths. One of the standard drugs for liver cancer patients is lenvatinib, but lenvatinib has dangerous side effects such as hypertension. Previous studies reported that jackfruit root extract (Artocarpus heterophyllus Lam.) contains prenylated flavonoid compounds known to have anticancer activity. This study aims to find compounds that have the potential to the anticancer liver from jackfruit root by understanding the interaction between prenylated flavonoid derivative compounds against the VEGFR2 receptor (PDB ID: 3WZE) in silico. The methods include toxicity and pharmacokinetic screening, drug scanning, docking, and molecular dynamics simulation. The toxicity, pharmacokinetic, and drug scans of cycloartocarpesin are better than lenvatinib. The docking cycloartocarpesin compound showed ∆G -8.49 kcal/mol and Ki 0.59967 M lower than lenvatinib by forming the same hydrogen bond at residue Glu885. The molecular dynamics simulation of the cycloartocarpesin compound in the MM-GBSA calculation method resulted in a ∆Gtotal of -56.641 kcal/mol. The cycloartocarpesin compound is predicted to be used as a candidate for liver anticancer drugs because it has better stability and affinity than lenvatinib.

Published: April 2023

Cimahi City is experiencing raw water insecurity. This requires the local government to look for new water sources, such as rehabilitating the condition of existing lakes in their area so that they function again as raw water lake. This study aims to analyze water quality and parameters that exceed quality standards and to calculate the status of lake water quality. The data will be the basis for preparing priority recommendations for lake management. The calculation of this method uses the Pollution Index (PI) method. The lakes studied were lakes located at the Cimahi City Government location, at the Cibabat Hospital, Setiamanah, Ciseupan, and the Cimahi City Infantry Brigade Complex. Based on research results in 2021, all lakes will be in the moderately polluted category, while in 2022 they will be in the low-moderate pollutant category. Lake water quality that has improved is Setiamanah Lake and that in the Cimahi City Infantry Brigade Complex. The two lakes originally had moderate to moderate polluted status with an index value of 8.40 to 4.94, so efforts and control strategies are needed to reduce pollution in the 5 lakes.

Authors: Hutagalung Ira Rumiris , Rachman Indriyani
Published: April 2023

A heavy dependency on online shopping platforms and home delivery, together with emerging post-pandemic responses from developing nations like India, China, Brazil, and primarily Indonesia, sum up a surge in demand for unsustainable plastic packaging techniques. Consumer preference as the center of successful commercial strategy and become a consideration in waste management studies. This study aims to develop an understanding of consumer preference factors as a response to tackling the plastic problem due to the online delivery system in Indonesia. Google's web-based platform is used to capture the number of online deliveries in a weekly period. A five-level Likert scale measures attitudes, social norms, or perceptions toward a constructed questionnaire. From the ordinal regression analysis, younger people intend to consume more with online platforms, and the more people don't have a proper waste collection, the higher they will consume online plastic delivery.
Internal Governance Mechanisms and Performance of Microfinance Institutions in Togo
Authors: Mowu Kofi , Boubacar Hamadou
Published: April 2023

Despite the boom in microfinance in Togo, the sector is seriously shaken by serious crises that threaten its performance and cast doubt on its sustainability. To explain performance crises to which microfinance institutions are subject, governance is regularly mentioned. This paper aims to identify internal governance mechanisms that can influence microfinance institutions’ performance in Togolese context. It is found out at the end of this paper that board of directors (the board size, presence of women on the board, duration of directors’ term of office and frequency of board meetings) influences financial and social performance of MFIs. On the contrary, the fact that MFI belong to a network or not, and its legal status have no effect on its performance.
Why Has Somaliland Not Been Recognised as A Sovereign State?
Authors: Issa-Salwe Abdisalam M. , Osman Abdullahi Salah
Published: April 2023

After the collapse of the Somali state, civil war followed, leading people to turn to their ancestral homeland. Consequently, rudimental local administrations were formed with a provision of becoming part of a decentralised governance system in Somalia. However, one region stood differently by declaring itself a separate state, Somaliland, within the boundaries of the former British Somaliland Protectorate. To overcome the objections of African countries about the session, Somaliland claimed that its declaration of independence in 1991 was supposed to be a dissolution of the union rather than a declaration of separation. This idea follows in the footsteps of other failed federations, such as the United Arab Republic, which included Egypt and Syria from 1958 to 1961, or the Senegambia Confederation, which existed between Senegal and the Gambia from 1981 to 1989. These failed political unions symbolized the breakup of that union and the restoration of the protectorate's original, pre-1960 borders. (Gordon, 2023) Britain granted Somaliland independence on June 26 1960, and after four days, it joined with the former UN Italian Somaliland Trusteeship Territory to form the Republic of Somalia. Thus, Somaliland's case differed markedly from the other regions as it wanted to stand as a separate nation-state within Africa. Yet, over thirty years have passed, and Somaliland has not been recognised as a sovereign entity. To answer why it happened, we have to look at the historical factors on state formation in Africa and how newly independent countries treated colonially inherited boundaries.
A Simple Stuck-at-faults Detection Method in Digital Combinational Circuits
Authors:   L’viv Polytechnic National University, Rytsar Bohdan Ye.
Published: April 2023

This paper considers the new method of detection (diagnostic) stuck-at-faults (0/1) in digital combinational circuits based on a numerical set-theoretical approach. Compared to known methods and algorithms, the proposed approach differs in simpler implementation of searching for vectors of test codes at arbitrary points of the studied logic circuit. A few simple set-theoretical operations and procedures are sufficient to determine the location and the type of a stuck-at-fault (0/1). This is evidenced by the presented examples of application of the proposed method, that are borrowed from the publications of well-known authors.

A significant increase in computer performance, the accumulation of a large amount of data necessary for training deep neural networks, the development of training methods for neural networks that allow you to quickly and efficiently train networks consisting of a hundred or more layers, has led to significant progress in training deep neural networks. This allowed deep neural networks to take a leading position among machine learning methods. In this work, neural network paradigms (and their methods of training and functioning) considers, such as Rosenblatt perceptron, multilayer perceptrons, radial basis function network, Kohonen network, Hopfield network, Boltzmann machine, and deep neural networks. As a result of comparative consideration of these paradigms, it can be concluded that they all successfully solve the tasks set before them, but now, deep neural networks are the most effective mechanism for solving intellectual practical tasks.

Introduction. Modern researches at the domain of radiotechnical devices and parts are showing that mean time between failures often is omitting during the brand new device designing process. Purpose of the development is to improve the method of the reliability values evaluation of the objects with variable structure including the different sets of elements working time at all possible usage modes as intended. The set-theoretic models of objects that are allowed to estimate power of element subsets quantitatively used in different modes of operation for the purpose of evaluation the reliability indicators of radio-electronic means depending on the structure of the object and the order of changing modes of operation. With the help of the mathematical apparatus of set theory, it has been proven that the reliability of radio-electronic devices will be maximum at the minimum power of the elements used during operation and vice versa. Methods. Evaluation method is needed to take into account vast majority of the minor aspects that were not included before during the calculation procedures: multi-mode work, multi-functioning, excess availability that leads to the object structure changing during its usage for purpose. Results. Taking the fifth-generation station for the experiment, several detail sets were chosen for installation into the device. Competence of the repair service, quality of the details, work-mode was taken into account for the certain result calculation achieving. Conclusion. Brand new, detailed method has been developed for the effectiveness of the objects with variable structure evaluation. Multimode availability could be a significant reliability improving feature at the devices with such structure. Also, evaluation of some separate parts of the device structure would be much more useful for the working period prolongation than evaluation of the device as a whole.

The article focuses on the development of an information search and protection system based on a Bayesian trust network as a measure of document relevance to the user’s query. The result is the development of search system structures and algorithms with relevance evaluation when searching the Internet, the implementation of data transmission with an adaptive database for storing decisions. If the need arises, when the goal set before the user cannot be achieved without involving additional information, the adaptive database sends a request to the search system, which in turn collects the necessary information. Mathematical formalization of the definition of relevant decisions was carried out. A graph was modelled, which was built based on Bayesian Trust Networks (BTN) in the GeNIe application package.
EXPERIÊNCIAS DE MOVIMENTO
Authors: Basei Andréia Paula
Published: April 2023

O texto propõe um conjunto de questões que vão ao encontro das diretrizes traçadas pela BNCC (2017), para pensar um propósito para a Educação Física na Educação Infantil fundamentado na importância das experiências de movimento. A experiência e o saber da experiência ocupam um lugar fundamental no âmbito da Educação Física. De maneira insubstituível, conhecer neste campo do conhecimento, requer entregar-se à experiência do movimento como forma de ser e estar no mundo, de compreender o mundo pela ação. Para isso, defendemos a necessidade de proporcionar, de forma qualificada, o maior e mais diversificado repertório de experiências de movimento para as crianças, organizadas didaticamente em: experiência corporal, material e de interação social. As potencialidades educacionais das experiências de movimento e do “se-movimentar” no contexto da Educação Física na Educação Infantil são ilimitadas, pois quanto maior for o estímulo para novas experiências maior e mais exitoso será o desenvolvimento da criança.

As pesquisas pós-críticas se caracterizam, também, por criarem metodologias que articulam procedimentos diversos para analisarem diferentes currículos. Apresenta-se, aqui, a metodologia utilizada para compreender como se organizou um currículo da cidade vivido por crianças organizadas em uma experiência de educação integral, a partir da articulação da etnografia educacional e da análise de discurso foucaultiana. Além de apresentar as ferramentas utilizadas para a produção das informações, aponta-se posturas adequadas para esse fazer metodológico. Apresenta-se, por fim, algumas reflexões suscitadas pela articulação desses procedimentos.
GIRAS DE ESCREVIVÊNCIAS
Authors: Oliveira Iris Verena
Published: April 2023

O artigo apresenta o diálogo entre a novela “Sabela” de Conceição Evaristo e os questionamentos ontoepistemológicos produzidos pela filósofa Denise Ferreira da Silva, para cunhar proposições metodológicas para pesquisa no campo do currículo. Sonhos, narrativas ficcionais e o universo mitológico afro-brasileiro inspiram os modos de fazer pesquisa construídos, a partir das giras de escrevivências. A partir do conceito de escrevivência cunhado por Evaristo e das refrações infinitas produzidas pelos abebés de Oxum e Iemanjá, (EVARISTO, 2020) o texto convida para produções metodológicas fundadas em epistemologias que refutam o sujeito universal das narrativas modernas, ao tempo em que apontam para ontologias que não obliteram a racialidade. O texto questiona o uso de dados como remetimento à realidade nas pesquisas em educação e defende um modo de pesquisar pelo encontro, a partir das giras de escrevivências. O diálogo entre profissionais de educação que reconhecem o currículo construído na escola e seus atravessamentos na engrenagem racial geraram interpelações à teoria curricular, uma vez que os procedimentos metodológicos do campo reiteram fundamentos lastreados na noção de sujeito transparente e na distribuição desigual da condição ontológica, a partir da noção iluminista de humanidade. O texto defende que acionar as escrevivências como proposta metodológica é apontar para miragens de processos intermináveis de perturbações da identidade, (DERRIDA, 2001) reconhecendo o onticídio (WARREN, 2021) que atravessa a experiência de pessoas negras, cuja integridade permanece em risco.

O dossiê pretende estimular conversações sobre os modos de fazer pesquisas no campo do currículo, considerando experimentos, criações e fabulações metodológicas que apontem os usos e limites da categoria currículo, a partir e para além do Ocidente.  O intuito é apresentar tensionamentos, resistências, subjetividades diaspóricas, identidades fraturadas, intersecções e a diferença nas práticas e políticas que se desenrolam no ambiente escolar, na relação de profissionais da educação com os movimentos sociais, instituições públicas regulatórias, bem como nas esquinas e nas frestas da vida. Após a virada qualitativa nas pesquisas em educação observa-se a ampliação do número de pesquisas que investem em métodos e técnicas voltados para acessar o “chão da escola”, seja por observações, entrevistas ou conversas, tais estratégias insistem no espaço formativo como lócus para a coleta de dados, reiterando noções de sujeito, autonomia e realidade, que por vezes se chocam com o referencial teórico mobilizado. Nesse sentido, interessa questionar como a produção de mapas conceituais articulam-se com as encruzilhadas, os híbridos, as conversações e com as autobiografias. Em que medida, as pesquisas sobre currículo, produzidas a partir de outros pontos de vista e epistemes têm possibilitado deslocamentos nos pilares ontológicos, éticos e epistemológicos das metanarrativas modernas.

Objective: to investigate the efficiency of a device that generates pulsatile flow during constant-speed axial-flow pump operation for use in left ventricular assist devices.

Materials and methods. The pulsatile flow-generating device, hereinafter referred to as «pulsator», consists of a variable hydraulic resistance made in the form of a hull. A tube of elastic biocompatible material featuring an inner diameter of 11 mm is installed inside it. In the systolic phase of the left ventricle, due to systolic pressure, the elastic tube is fully opened, minimizing resistance to blood ejection. In the diastolic phase, due to suction action of the flow pump operating in constant revolutions, the elastic tube partially closes, creating additional hydraulic resistance to blood flow, which leads to reduced diastolic aortic pressure. Comparative assessment of axial-flow pump operation in pulsating and non-pulsating modes was carried out on a hydrodynamic stand that simulated the cardiovascular system. The following indices were calculated: arterial pressure pulsation (Ip), in-pump flow pulsation (AQ), energy equivalent pressure (EEP) and surplus hemodynamic energy (SHE).

Results. When comparing axial-flow pump operation in pulsatile and continuous mode, arterial pressure pulsation index, in-pump pulsation index, and SHE index increased by 2.13 ± 0.2, 3.2 ± 0.2, and 2.7 ± 0.15 times, respectively, while EER index remained unchanged.

Chronic heart failure (CHF) against the background of congenital heart disease, mostly in early childhood, or various forms of cardiomyopathies, more common in teenage age, represents an important cause of morbidity and mortality in the pediatric population [1, 2]. Due to the increase in the number of patients suffering from refractory end-stage CHF over the last two decades, and the current shortage of donor organs in pediatric practice, the issue of long-term mechanical circulatory support (MCS) is becoming increasingly a pressing problem. Patient management is a multidisciplinary task, since prolonged use of anticoagulant and antiplatelet therapy to prevent ventricular thrombosis has potentially life-threatening complications - acute hemorrhagic stroke and bleeding of varying severity.
