18F-Fludeoxyglucose Absorbed Dose Estimation in Fetus during Early Pregnancy
Authors: Ahmadi Nemat , Karimian Alireza , Nasrabadi Mehdi Nasri
Published: August 2022

The purpose of this study is to assess a rare case of fetal radiation absorbed dose here through 18F-Fludeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) in early pregnancy (5-week-old fetus). The fetal absorbed dose due to the radiation emitted from the mother's body, the fetus self-dose, and the dose received from CT were computed. The 35-year-old patient, weighing 85 kg, was injected with 370 MBq of 18F-FDG. Imaging started at 1 h with CT acquisition followed by PET imaging. The photon and positron self-dose was calculated by applying the Monte Carlo (MC) GATE (GEANT 4 Application for Tomographic Emission) code. The volume of absorbed dose from the mother's body organs and the absorbed dose from the CT were added to the self-dose to obtain the final dose. The volume of self-dose obtained through MC simulation for the fetus was 3.3 × 10-2 mGy/MBq, of which 2.97 × 10-2 mGy/MBq was associated with positrons and 0.33 × 10-2 mGy/MBq was associated with photons. Biologically, the absorbed dose from CT, 7.3 mGy, had to be added to the total dose. The absorbed dose by the fetus during early pregnancy was higher than the standard value of 2.2 × 10-2 mGy/MBq (MIRD DER) because, during the examinations, the mother's bladder was full. This issue was a concern during updating standards.
Investigation the Efficacy of Fuzzy Logic Implementation at Image-Guided Radiotherapy
Authors: Torshabi Ahmad Esmaili
Published: August 2022

At image-guided radiotherapy, technique, different imaging, and monitoring systems are utilized for (i) organs border detection and tumor delineation during the treatment planning process and (ii) patient setup and tumor localization at pretreatment step and (iii) real-time tumor motion tracking for dynamic thorax tumors during the treatment. In this study, the effect of fuzzy logic is quantitatively investigated at different steps of image-guided radiotherapy. Fuzzy logic-based models and algorithms have been implemented at three steps, and the obtained results are compared with commonly available strategies. Required data are (i) real patients treated with Synchrony Cyberknife system at Georgetown University Hospital for real-time tumor motion prediction, (ii) computed tomography images taken from real patients for geometrical setup, and also (iii) tomography images of an anthropomorphic phantom for tumor delineation process. In real-time tumor tracking, the targeting error averages of the fuzzy correlation model in comparison with the Cyberknife modeler are 4.57 mm and 8.97 mm, respectively, for a given patient that shows remarkable error reduction. In the case of patient geometrical setup, the fuzzy logic-based algorithm has better influence in comparing with the artificial neural network, while the setup error averages is reduced from 1.47 to 0.4432 mm using the fuzzy logic-based method, for a given patient. Finally, the obtained results show that the fuzzy logic based image processing algorithm exhibits much better performance for edge detection compared to four conventional operators. This study is an effort to show that fuzzy logic based algorithms are also highly applicable at image-guided radiotherapy as one of the important treatment modalities for tumor delineation, patient setup error reduction, and intrafractional motion error compensation due to their inherent properties.
Predictors of Response to Cardiac Resynchronization Therapy
Authors: Parikh Jignesh , Patil Rajendra , Jadhav Ajitkumar Krishna
Published: August 2022

Introduction:

Cardiac resynchronization therapy (CRT) has revolutionized the treatment of cardiac dyssynchrony in chronic heart failure (HF), yet, complications and failures are reported in some patients. We aim to determine the predictors of response to CRT through clinical, electrocardiographic ECG, and echocardiographic assessment of patients following CRT and recommend the best practices to achieve optimum results for patients.

Methodology:

We analyzed the history, clinical examination, brain natriuretic peptide (BNP) levels, ECG, and echocardiography findings of 35 patients before CRT and on day 7 and day 180 following CRT.

Observations:

71.4% of patients responded to CRT and 28.6% were nonresponders. The responders had fewer hospitalizations for HF. They showed a significant improvement in the New York Heart Association (NYHA) class, mean 6 min walk distance (6MWD), BNP level, QRS duration, and echocardiographic parameters on day 7 and day 180. The duration of HF ≤3 years, NYHA class III–IV symptoms, baseline 6MWD ≥240 m, QRS duration ≥150 ms, LVEF ≥25%, septal to posterior wall motion delay ≥130 ms, and mean pulmonary arterial pressure <50 mmHg were identified as the strong predictors of response to CRT.

Recommendations:

Patients with symptomatic HF should undergo early CRT to reduce recurrent hospitalizations and those with NYHA Class III–IV symptoms should be offered CRT before the duration of HF exceeds 3 years. BNP levels and echocardiography are invaluable tools to assess outcomes following therapy. A multiparametric, echocardiographic approach is helpful in selecting patients likely to undergo reverse remodeling after CRT and predicting outcomes.

Objective:

The aim of this study is to investigate the postoperative outcomes in post COVID versus non-COVID patients undergone cardiac surgery.

Materials and Methods:

A retrospective cohort study to analyze the impact of COVID-19 in patients undergoing elective or emergency cardiac surgeries. A total of 512 patients were included in the study over a period of 6 months. The study consists of 35 post-COVID patients and 477 non-COVID patients. All data were collected from previous medical records and hospital database. The clinical outcomes and mortality of post-COVID patients were compared with a cohort of non-COVID patients. The endpoints were compared using t-test or Chi-squared test.

Results:

Among the post-COVID patients, 54.3% (19) of the post-COVID patients were under COVID category A followed by category B 28.6% (10) and category C 17.1% (6). About 50% of post-COVID patients had complications, especially pneumonia and myocardial infarction following COVID-19. Around 43% of patients showed fibrotic changes in computed tomography (CT) Thorax at the time of admission for surgery. 63% showed CT score in between 1 and 5. The mean COVID antibody titer was 158 U/ml. Majority of the surgeries were coronary artery bypass graft and significant difference was observed in the requirement of intra-aortic balloon pump in post-COVID patients (P < 0.0001). No postoperative mortality reported in post-COVID patients. The postoperative outcomes and survival rates were almost similar in both groups.

Conclusion:

In our study, the post-COVID patients were recover in a similar way as non-COVID patients after cardiac surgery.
Systemic Complications and Imaging Challenges of Sickle Cell Disease in Sub-Saharan Africa
Authors: Inah Grace B. , Ekanem Emmanuel E. , Obiora Christiana I. , Ogbole Godwin I.
Published: August 2022

With improved life expectancy of people living with sickle cell disease (SCD) as a result of modern interventions, chronic problems such as pulmonary, abdominal, cardiovascular, musculoskeletal, and obstetric challenges are more often encountered. The need for radiological examination is, therefore, growing for the early diagnosis of these complications and improved prognosis. The emphasis, therefore, should be toward safer diagnostic options such as ultrasonography, transcranial Doppler ultrasound, and echocardiography as repeated radiation is counterproductive. This review is aimed at highlighting the imaging challenges encountered in the management of SCD in sub-Saharan Africa and possible ways of mitigating them. We reviewed available electronic literature in the last 20 years, especially articles from Google Scholar and PubMed with search keywords of imaging challenges, sickle cell disease, and sub-Saharan Africa. The challenges identified in this review include lack of institutional infrastructure, poor equipment availability, weak health and imaging personnel capacity, treatment affordability, service accessibility, and poor research and training facilities. With the increasing longevity of SCD individuals in sub-Saharan Africa, imaging requirements are rising. Repeated exposure to radiation should be minimized as much as possible. Engagement of the private sector through public-private partnership in equipping health institutions with radiological equipment, as well as training of appropriate personnel for their deployment is strongly recommended to enhance care, prevent complications, and improve outcomes for SCD in sub-Saharan Africa.
Congenital Intracranial Teratoma Masquerading as Encephalocele
Authors: Adamu Yahuza Mansur , Hikima Mustapha Shuaibu , Lawal Yusuf
Published: August 2022

Teratomas are rare tumors accounting for only 0.5% of all intracranial tumors. However, they are considered as the most common congenital brain tumors present at birth. Commonly, they are found in the sacrococcygeal region, head and neck, gonads, and the mediastinum, although they may be found in other parts of the body. An encephalocele on the other hand is an extracranial lesion with intracranial contents through a defect in the skull. The higher prevalence of encephaloceles often leads to misdiagnosis of other congenital diseases of the brain like tumors as encephalocele. We present a 29-day-old child who presented to the hospital on account of swelling on the skull which was noticed since birth and associated absence of hair over the swelling covered by intact skin with initial impression of encephalocele made. The role of imaging in these patients precisely computed tomographic scan and magnetic resonance imaging (MRI) cannot be overemphasized for appropriate diagnosis and surgical intervention. A radiological diagnosis of congenital intracranial teratoma was made and the patient had surgical excision of the tumor. Congenital intracranial teratoma are rare congenital malformations. The present report demonstrates the classic imaging features as seen on plain radiographs, computed tomography, and MRI which are indispensable for subsequent surgical intervention.
Current Status of Bone Single-Photon Emission Computed Tomography Combined with Computed Tomography in Evaluation of Foot and Ankle Pain
Authors: Veerwal Hardik , Meena Anjali , Dhingra Vandana Kumar
Published: August 2022

The complex anatomy of the foot and ankle makes it a clinical challenge to reach a final diagnosis in patients with foot and ankle pain. Conventional imaging modalities such as radiography, computed tomography (CT), and magnetic resonance imaging (MRI) play a vital role in making a diagnosis in patients with foot and ankle pain. MRI is considered to be the go-to modality for foot and ankle pathologies, but it has limitations in patients with metallic implants and claustrophobia. With wider availability and excellent imaging quality of new-age gamma cameras, bone single-photon emission computed tomography combined with CT (SPECT/CT) with technetium-99m (99mTc) labeled bisphosphonates has come into forefront for diagnosis of foot and ankle pathologies. SPECT is known to have high sensitivity to detect lesions but with low specificity. This low specificity was overcome by the introduction of SPECT/CT, a hybrid imaging modality that involves anatomical correlation of CT with the functional imaging of SPECT. SPECT/CT is extremely useful for evaluating the common but challenging causes of foot and ankle pain such as osteoarthritis, impingement syndrome, infection, inflammation for detecting optimal sites for intraarticular injection, and evaluation of diabetic foot. This review article aims to discuss various imaging modalities available for foot and ankle evaluation and the current status of SPECT/CT in diagnosing various foot and ankle pathologies.
Early Experience of Percutaneous Transhepatic Sphincteroplasty with Occlusion Balloon Evacuation of Biliary Stones in a Lagos, Nigeria Center

Published: August 2022

Untreated obstructive jaundice secondary to common bile duct stones can lead to serious metabolic and life threatening complications. Three options exist for CBD stone evacuation; endoscopic retrograde cholangiopancreatography (ERCP), surgical exploration, and percutaneous transhepatic biliary intervention. Open surgical exploration has been the mainstay of management of CBD stones in Nigeria due to limited access to less invasive approaches. The availability of percutaneous transhepatic intervention can serve as an alternative. For this case series, the first consecutive patients who were treated for choledocholithiasis with percutaneous sphincteroplasty between March 2020 and December 2020 at a center in Lagos are described. A total of 6 patients underwent stone evacuation over the study period. The technical success of sphincteroplasty and CBD stone evacuation was 100% in all patients (n = 6) at the first attempt. This series illustrates that percutaneous transhepatic sphincteroplasty for clearance of biliary stones is technically feasible and available to Nigerian patients.
Safety and Efficacy of Percutaneous Ultrasound-Guided Needle Aspiration of Liver Abscesses in a Resource-Scarce Environment
Authors: Baduku Tokan Silas
Published: August 2022

Background:

Liver abscess is a condition found in both the developed and the developing countries (including Nigeria), which was normally treated with drugs alone. Refractory patients who were initially treated by open abdominal surgery are now successfully treated with minimally invasive approach from increased availability and access to ultrasound in low-resource settings where the burden of liver abscess is still significant. To our knowledge, not much data are available in our environment on a large series of patients with liver abscess managed solely with percutaneous needle aspiration under ultrasound guidance in combination with systemic and local abscess sac antibiotic treatment. We, therefore, report our experience in the management of liver abscess in Goshen Diagnostic Services, Kaduna, Nigeria (a private diagnostic center).

Aim:

The aim of this study was to describe our experience in the ultrasound-guided percutaneous management of liver abscesses over a period of 8 years in a private diagnostic center and to review the literature.

Materials and Methods:

This prospective study was conducted over an 8-year period at Goshen Diagnostic Services (a privately owned diagnostic outfit with only outpatient facility), Kaduna, Nigeria, from June 2012 to May 2020, involving 77 adult patients (62 male and 15 female) with liver abscess who were referred from various medical facilities within the city just for drainage purposes.

Results:

A total of 77 patients were eligible for the study consisting of 62 males and 15 females (male-to-female ratio of 4:1). Fifty-eight (75.3%) of them were referred from government/public hospitals, whereas 19 (24.7%) were from privately owned medical centers. Fifty-three (68.8%) patients were referred when still on admission in the various hospitals, whereas 24 (31.2%) came as outpatients. Twenty-eight percent of them required only a single aspiration, whereas 38.9% and 24.7% had to go for a second and third episode, respectively. The success rate was 100% after 6 months of follow-up.

Conclusion:

Liver abscess management used to be a surgical dilemma with substantial morbidity and mortality but has currently become minimally invasive. At present, morbidity and mortality have markedly diminished, with reduced cost to the patient. The direct infiltration of drugs into the abscess sac has improved the success rate.
Interacting particle systems with long-range interactions: Approximation by tagged particles in random fields
Authors: Nota Alessia , Velázquez Juan J.L. , Winter Raphael
Published: August 2022

In this paper, we continue the study of the derivation of different types of kinetic equations which arise from scaling limits of interacting particle systems. We began this study in [Atti Accad. Naz. Lincei Rend. Lincei Mat. Appl. 32 (2021), 335–377]. More precisely, we consider the derivation of the kinetic equations for systems with long-range interaction. Particular emphasis is put on the fact that all the kinetic regimes can be obtained approximating the dynamics of interacting particle systems, as well as the dynamics of Rayleigh gases, by a stochastic Langevin-type dynamics for a single particle. We will present this approximation in detail and we will obtain precise formulas for the diffusion and friction coefficients appearing in the limit Fokker–Planck equation for the probability density of the tagged particle

f(x,v,t)

, for three different classes of potentials. The case of interaction potentials behaving as Coulombian potentials at large distances will be considered in detail. In particular, we will discuss the onset of the the so-called Coulombian logarithm.
Breathing Divine Breath: on the Greco-Egyptian Sources of Hesychasm
Authors: Kleinhempel Ullrich
Published: August 2022

The genesis of Hesychasm is still quite unresolved. In this article, the assumption that its origins lie in late Greco-Egyptian Antiquity, in the eastern Mediterranean, and that Yoga contributed to it, remain in the background. The normative form of Hesychasm, referred to here, is that described briefly by St. Gregory Palamas. In this article, two constituents, presented by him as essential, are investigated for their likely roots in the Greco-Egyptian syncretism of Antiquity. It emerges, that meditative ‘breathing’ – which Palamas connects to the drawing inward of the mind and awareness of the meditator – also serves as a ‘vehicle’ for drawing in the divine spirit, and the power of God, into the centre of a person, the ‘heart’ – that comprises the body, the soul, and the mind. This latter is important in testimonies of GrecoEgyptian syncretism, especially the Magic Papyry. ‘Magic’ is framed here religiously. This indicates that it is believed to be effective and theologically legitimate. The inclusion of Biblical elements in these texts suggest, that boundaries to Judaism and later to Christianity, were fluid. Therefore, the concepts and practices presented here, are to be regarded as important to a profound understanding of Hesychasm. Palamas’ instruction, ‘to send the spirit (nou=j) inwardly by means of breathing, should therefore not be understood as limited to the persons mind and consciousness, but also, as signifying the divine spirit (nou=j), with its power, inwardly, and thus, to participate in it, for divinisation and for acting by this power.

Promoting Prospective Mathematics Teachers’ Professional Vision on a Whole-class Reflective Discussion: Contributions of Digital Resources
Authors: Rodrigues Renata Viviane Raffa , Oliveira Hélia Margarida , Cyrino Márcia Cristina de Costa Trindade
Published: August 2022

The present study aims to understand how the professional vision of prospective teachers (PTs) regarding whole-class reflective discussion develops as they explore a multimedia case (MC) in a mathematics teacher education course. The data come from the written productions of seven groups of PTs (N=15) related to whole-class discussion of one 6th grade lesson in two sections of the MC: first, they have focused on the teacher’s lesson plan and on her intentions for the whole-class discussion aiming at the students’ algebraic thinking; and in the second, they have analysed two video episodes of that lesson phase. The results show an integrated development of two processes of PTs’ professional vision – noticed events and the nature of the reasoning about them – with significant evolution from one section to another as they explore the MC. The study shows PTs’ alternative ways of accessing and making sense of the complexity of both ambitious and authentic teaching practices that can also be employed in at distance teacher education and mitigate the consequences of the impossibility to access the classrooms, such as that resulting from the recent COVID-19 pandemic.

Published: August 2022

This study focused on capturing the research landscape of past studies related to mathematics problem solving in elementary education from 1969 to 2021 through a bibliometric analysis. All the 159 bibliographic data involved were extracted from the Scopus database. The findings show an increasing trend in publication and citation over the years. The publications were distributed over six continents, namely North America, South America, Europe, Asia, Oceania, and Africa. The United States emerged as the most productive country with the highest number of publications, g-index, and h-index. The foci of the research are (i) problem solving involving arithmetic and mathematical representations, (ii) mathematics teaching and learning based on word problems, (iii) cognition of pupils and affective domains in mathematics problem solving, and (iv) problem solving involving algebra and teachers' role in problem solving learning. The findings of this study serve as a guideline for researchers to understand the niche area and set forth pathways for future research.

Published: August 2022

The study of academic achievement continues to be one of the "star" topics in the field of education today because of its great importance as an indicator for assessing educational quality and has therefore been studied from various perspectives. In this regard, the aim of this study was to study which dimensions of self-concept (behavioral, intellectual, physical, lack of anxiety, social or popularity and subjective happiness-life satisfaction) predict performance in each core subjects (Spanish Language and Literature, Mathematics, Natural Sciences, Social Sciences and First Foreign Language (English)). For this purpose, a sample of 116 students from the last cycle of Primary Education (10-12 years) was selected by accessibility and administered a multidimensional Self-Concept Scale. The data were analyzed using the multiple linear regression technique, evaluating the Root Mean Squared Error, statistical power and effect size in all of them. The main results show that intellectual self-concept is the most important predictor of academic achievement. Therefore, schools should be aware of the importance of fostering confidence and expectations of success in students' academic tasks.
Student Teachers' Perceptions of the Connection between Literacy, Equality and Digitalization
Authors: Maunula Minna , Lähdesmäki Sirkku
Published: August 2022

Digitalization has many implications for the development of equality in societies and is also reflected in education. In a digitalized world, literacy is an essential skill for both individual and societal development. This study explores Finnish student teachers' perceptions of the connection between literacy, equality, and digitalization. The research material consists of professional opinion pieces written by student teachers (N=37). The qualitative study examined student teachers' perceptions of literacy, equality, and digitalization. Student teachers' perceptions concerned pupils' polarizing backgrounds for learning, literacy instruction and the challenge of differentiating classes, deterioration of literacy and other learning, and positive aspects of literacy learning. The results show that student teachers recognize the connection between literacy and digitalization and their broad impact on societal development and equity. As future teachers, they perceived the impact of the development of inequalities on everyday school life and on opportunities to learn key skills as a challenge. The results show that the polarizing starting points for pupils is a worrying trend and challenges the future teacher in a digitalizing world. The results of the study underline that teacher training and teachers are important societal actors and reformers.

Published: August 2022

Professional development programs (PDs) for in-service teachers are usually structured to deliver standardized content. However, considering the differences in the teaching practices utilized by teachers of different subjects, their needs and expectations may vary. Thus, this study develops an instrument to determine in-service teachers’ expectations regarding PDs. Themes regarding the PD expectations of teachers were created based on a detailed literature review and authors’ field experiences. In line with these themes, an item pool comprising 51 items was created. The developed instrument was applied online to 322 teachers from different provinces of Turkey and teaching different subjects. Exploratory factor analysis was performed on the dataset to ascertain the construct validity of the instrument. As a result of the analyses, the finalized instrument comprised 49 items and 6 dimensions; support, practice, learning, student success, organization, and career. The Cronbach’s alpha internal reliability coefficient of all items in the finalized instrument was .94. These findings show that the instrument is a valid and reliable data collection tool for determining teacher expectations of PDs for identified themes. This instrument will be particularly useful in exploring the expectations of teachers while designing PDs and determining the extent to which current PDs meet teachers’ expectations.

Published: August 2022

The STEAMTEACH (STEAM Education for Teaching Professionalism) project works with teacher trainers to develop a program of Transcultural STEAM Professional Development for in- and pre-service teachers. Following a literature review, a semi-structured questionnaire then interviews approach was used to elicit current practice, challenges for teachers and recommendations from Austrian teacher trainers. These recommendations were then compared with and supported by STEAM academic literature. It was found that none of the institutions offered a STEAM approach and it does not appear in the curriculum. Indeed, this fact is the primary challenge to overcome. Recommendations were that teachers should work in multidisciplinary, supportive, collaborative groups and networks. Problem and project-based learning were identified as key learning methodologies. A mix of physical and on-line working synchronously and asynchronously was recommended for online professional development because teachers can participate irrespective of time and place. Educational technology can support collaboration, and also ‘plug and play’ technologies including game-based learning can be inserted into an overall STEAM approach. The affective factor was judged essential for students and teachers.
Examination of Preferences of Teachers for Educational Program Design Approaches
Authors: Bulut Ayhan
Published: August 2022

This study aims to examine preferences of teachers for curriculum design approaches in terms of various variables. In this study, the relational survey model, one of the quantitative research methods, was used. The population of the study consists of branch teachers working in all types and levels in public schools in the central districts of a province of Turkey. Since the population of the study is very large, sampling was made using the typical case sampling method. The sample of this study consists of 415 teachers who voluntarily supported it. During the study process, the data necessary to reach the goal were obtained by using two scales: "Personal Information Form" and "Teachers' Curriculum Design Approach Preferences Scale". Since the data collected from the scale showed normal distribution, t-test from parametric tests, one-way ANOVA test and Tukey test from Post Hoc tests were used to determine which groups differed in multiple comparisons. In the analysis of all data, the value of 0.05 was taken as the confidence level. As a result of the analysis of the findings obtained from the study, it was stated that the teachers' scores on the curriculum design approach scale were high, and they preferred to use problem-centered curriculum design approaches most in the learning-teaching processes, and at least they preferred to use subject-centered curriculum design approaches.
Student Teachers’ Views on Media Education Related to New Literacy Skills
Authors: Lähdesmäki Sirkku Anneli , Maunula Minna
Published: August 2022

High quality media education promotes media literacy and ensures citizens' smooth participation and engagement in the digital society. Digital media include powerful communication and interaction platforms that require new literacy skills. This study examines what new literacies can be found in the opinion writings of student teachers in relation to media literacy. The research material consists of 37 Finnish student teachers' opinion writings produced during the Media Education 2020 course. The aim of the study is to explore how student teachers identify new literacies as part of media education and how these new literacies are reflected in their opinion writings. As a result of the research, new literacies emerged from the data as a cultural phenomenon of our time. This was reflected in their views on the technological orientation of school and teaching and the importance of media education as a teaching task in schools. An important finding is that the textual subculture of social media is valued as a new form of literacy. The results show that while the narrative value of images, virtual game worlds and easy access to social media via smartphones were identified, the broad understanding of new literacies among student teachers is narrow. Perceptions of media education and new literacies are interlinked and the debate on their relevance as a social phenomenon should continue.
The Role of OT in Adapted CrossFit
Authors:   , Adams Emily
Published: August 2022

Background: A quarter of adults are diagnosed with a disability in the United States, with almost half considered being inactive (CDC, 2020). The population of persons with disabilities (PWD) are at higher risk for secondary health concerns due to a sedentary lifestyle (Diaz et al., 2019). CrossFit recently implemented their first adaptive division in 2021 (CrossFit, LLC, 2022), however there continue to be barriers preventing PWD from participating in CrossFit. Problem/Purpose: PWD may experience limited access to CrossFit due to structural and social barriers to access equipment and participating in movements. The purpose of this project was to develop a program that improves access to desired exercises and equipment in CrossFit for PWD. Occupational therapists (OT) have a role in adapted sports; however, participation in leisure is not always a focus. The person- environment-occupation-performance (PEOP) model was used to create a program that considered personal factors within the context of environment to enhance occupational participation for PWD. Methods: This project assessed the CrossFit environment, needs of the coaches, and analysis of CrossFit movements. Feedback on the effectiveness of the program was provided by the Adapted Training Foundation and through observations with coaches and adaptive athletes. Results: A comprehensive adapted CrossFit program was developed that included a synopsis of each qualifying disability and acquired injuries, injury prevention, an adaptive equipment resource, and a coaching resource for onboarding use. Further implementation is needed to understand program satisfaction and ability to improve access to participation for PWD in CrossFit.

Published: August 2022

Este artigo apresenta os resultados de um levantamento das pesquisas sobre o processo formativo dosacadêmicos dos cursos de licenciatura, em especial, no que se refere aos estudantes do curso dePedagogia. Delimita a análise ao momento de realização do estágio curricular obrigatório emdocência nos Anos Iniciais do Ensino Fundamental. Problematiza o papel do professor que recebe oestagiário em sua sala de aula, identificando os sentidos atribuídos a este profissional, comomediador entre a universidade e o campo de estágio. Procura compreender seu papel e suas possíveiscontribuições como co-formador de novas gerações de professores. Para isto, realizou-se umapesquisa do tipo Estado da Arte. Optou-se por fazer um levantamento das pesquisas disponíveis noCatálogo de Teses e Dissertaçõesda CAPES. Os dados coletados referem-se ao período compreendido entre os anos de 2010 e 2020.Por meio da análise dos dados, foi possível perceber a existência de dissímeis nomenclaturas para sereferir ao professor da escola campo de estágio: “Professor Regente”, “Professor Acolhedor”,“Professor Colaborador”, “Professor Experiente”, entre outras. O estudo apontou que o professorregente, mesmo que receba outro nome ou terminologia que o identifiquem como agente formativono processo de estágio, ainda é pouco pesquisado. Tal realidade poderia gerar lacunas deconhecimento que dificultam a compreensão do efetivo papel destes profissionais na formação dosnovos professores. No tocante ao momento de realização dos estágios supervisionados, sobre a formacomo este professor se reconheceria como formador ou corresponsável pelas novas gerações deprofissionais da educação, fica a dúvida sobre a existência de intencionalidade formativa na ação dosprofessores regentes, pois as pesquisas demonstram que em certa medida, há apenas uma reproduçãode modelos experienciais de docência, sem um compromisso com a formação dos futurosprofessores.

Bryophyllum pinnatum belongs to the family crassulaceae and is widely used in traditional medicine, especially in tropical areas. In the present study, extract yield and phytochemical constituents of chloroform extracts of Bryophyllum pinnatum leave prepared using two most commonly used extraction techniques known as cold maceration, and soxhlet extraction was investigated. Analysis using gas chromatography and mass spectrometry (GC/MS) was done on the extracted materials. The extract produced by the cold maceration method yielded ten (10) compounds, whereas the extract produced by the soxhlet extraction method yielded eight (8) compounds. Piperazine, 1-(2-adamantyl)-4-benzoyl, which made up the highest percentage of the 10 compounds found using the cold maceration method, had a concentration of 53.673%, while Pyrazine, 2,6-diethyl, had a concentration of 31.913% in the extract made using the soxhlet extraction method. The GCMS analysis's findings suggest that heat can change the composition of several phytochemical substances. The term thermo-liable compounds refer to those substances that are easily denatured or changed by heat. The variance in yield percentages and phytochemical compositions that has been observed is due to the employment of various extraction methods. The presence of these phytochemicals in B. Pinnatum leaves supports the use of the plants' leaves in the treatment of a variety of illnesses, including leishmaniasis, asthma, and ear pain, as several of the compounds discovered are known to have therapeutic properties.

OBJETIVO: describir el fenómeno que sucede a nivel psiconeuroendocrinológico del estrés y los circuitos de las personas que sufren depresión. MÉTODO: el presente ensayo científico, permite realizar el análisis de información fundamentada en investigaciones facilitando la comprensión sobre la magnitud del proceso neurológico que envuelve este trastorno. Explicar que la depresión es causada por un solo factor en un individuo es poco realista, como determinar que un solo sistema se encuentra involucrado en dicho proceso. RESULTADOS: el surgimiento de la neurociencia, ha permitido a los investigadores de la ciencia, estudiar diversos aspectos que se centran en los fundamentos de las ciencias de la salud desde la neuroanatomía, neuropatología, epigenética y ciencias diversas comprendiendo el funcionamiento del sistema nervioso, inmunológico y endocrino, con el objeto de comprender la complejidad del comportamiento humano y de los procesos cognitivos. CONCLUSIÓN: el trastorno depresivo asocia al estrés, debido a las alteraciones que existen en el eje hipotalámico. El cuál es el principal para los cambios físicos y ambientales. El estrés es uno de los factores que generan una mayor secreción de la hormona de la liberación de corticotrofina.
