Authors: Tian Feng , Miao Long , Xia Qimeng , Wang Ningfei , Hou Xiao
Published: February 2023

The large difference in the working performance of a hollow cathode plasma contactor between the ground and actual on-orbit environments will cause difficulties in selecting a ground-test schemes to fully simulate the contactor real on-orbit characteristics. In this study, the effect of the simulated anode size and structure, the simulated anode surface state, the flow rate of background working gas, and the background plasma density on the emission characteristics and plume structure of the contactor are studied. Three self-made simulated anodes of different sizes and structures are applied in the ground experiments. The change of anode surface state (particularly the ability of absorbing electrons) is realized by dividing the self-made simulated anodes into four double-separated regions and alternatively electrically isolating them. An additional gas channel and an auxiliary contactor are used to create background working gas and a low-Earth-orbit plasma atmosphere, respectively. The voltage–current curves as well as the plasma parameter distributions at the contactor exit and in the far-field regions are determined under different regimes and working conditions. The relationship between the contactor’s emission characteristics and plume structure is clarified. The experimental results could provide useful information for instructing the contactor design and developing a real on-orbit experiment plan.
Pain Science in Practice (Part 5): Central Sensitization II
Authors: Hoegh Morten
Published: February 2023

SYNOPSIS: Central sensitization is an umbrella-term for facilitated synaptic plasticity. This editorial explains wind-up, classical central sensitization, and long-term potentiation. Wind-up and LTP are generally considered homosynaptic, while classical central sensitization is classified as heterosynaptic. Wind-up is very short lived and unlikely to play a significant role in chronic musculoskeletal pain, however, both LTP and classical central sensitization could potentially be involved in chronic pain.

Transvenous embolization of a ruptured thalamic arteriovenous malformation supplied by the tuberothalamic artery
Authors: Vargas-Urbina John , Saal-Zapata Giancarlo , Durand-Castro Walter , Rodriguez-Varela Rodolfo
Published: February 2023

Background:

Basal ganglia and thalamic arteriovenous malformations (AVM) represent 10% of all AVM. They are associated with a high rate of morbidity and mortality due to their high hemorrhagic presentation and eloquence. Radiosurgery has been the first line treatment, whereas surgical removal and endovascular therapy are possible in selected cases. Deep AVM with small niduses and a single draining vein can achieve cure with embolization.

Case Description:

A 10-year-old boy with sudden headache and vomiting underwent a brain computed tomography scan that showed a right thalamic hematoma. Cerebral angiography revealed a small ruptured right anteromedial thalamic AVM with a single feeder arising from the tuberothalamic artery and a single drainage to the superior thalamic vein. Transvenous approach using precipitating hydrophobic injectable liquid 25%® achieved a complete obliteration of the lesion in a single-session. He was discharged home without neurological sequelae and maintained clinically intact at follow-up.

Conclusion:

Transvenous embolization of deep-located AVM as a primary treatment is curative in selected cases, with complication rates comparable to other therapeutic strategies.
Do Water Molecules Displaced by Hydrophobic Interactions Stabilize Antigen-Antibody Binding?
Authors: Nemeth Peter
Published: February 2023

Background: Antigen-antibody reactions are a special field of molecular interactions. The physicochemical nature of antigen-antibody binding and ligand-induced changes in the fine molecular structures of antigens during immunocomplex formation are less studied. However, these changes in the molecular appearance are extremely important for further molecular recognition. The major aim of this study is to clarify the physico-chemical modification of the antigen/hapten during immunobinding using model experiments. Methods: An appropriate model system was designed for our investigations: fluorescein-isothiocyanate (FITC, isomer I) was used as the antigen (hapten), and its interactions with a specific antibody (monoclonal anti-FITC IgG1) were analyzed using spectrophotometry, different spectrofluorimetric methods and fluorescence polarization, and Fourier-transform infrared spectroscopic methods. Results: Fluorescent polarization and infrared spectroscopic measurements detected a local decrease in the hydration degree in the submolecular area of the specific ligand between the small antigen (hapten) molecule and the hypervariable region of the specific IgG1, causing “rigidization” of molecular movements. Changes in hydration modified the molecular microenvironment, allowing them to influence further functions of both immunoglobulins and the antigen. Conclusion: Hydrophobic interactions with exclusion of water molecules around the binding sites seem to be thermodynamically strong enough for stable molecular binding without a covalent chemical interaction between the antigen and the antibody. The results of this study, together with data obtained in previous research, help understand the molecular dynamics of the antigen-antibody reaction better.

Published: February 2023

Aim: This study aimed to evaluate serum levels of 25-OH D3 (calcidiol) among students of the Faculty of Medicine Osijek, Croatia, thereby determining to what extent vitamin D deficiency is present. Methods: The present cross-sectional analysis was based on data collected from 60 participants. Blood sampling was done in March 2021. Concentrations of 25-OH D3 were measured using LC/MSMS procedure on Shimadzu LCMS 8050 and RECIPE kit for serum levels of 25-OH-D3. Results: The study was conducted on a sample of 60 respondents aged 19 to 28, of whom 16 were men and 44 were women. All subjects had a 25-OH D3 deficiency (<20 ng/ml), while 11 had an extreme deficiency. Mean 25-OH D3 concentration was 11.36 ng/ml, ranging from 7.70 ng/ml to 16.70 ng/ml. There was no statistical significance of 25-OH D3 concentration levels between the sexes (Student’s t-test, P>0.05). Conclusion: Vitamin D deficiency was detected in all subjects. In addition to the results of several other studies conducted worldwide that evaluated vitamin D status among medical students, this study further highlights the problem affecting this student subgroup.

Published: February 2023

Mitragynine pseudoindoxyl has recently attracted increasing attention as a promising analgesic alternative for pain management with considerably fewer side effects. Here, we describe the first enantioselective and scalable total synthesis of this natural product in addition to its C-20 epimeric congener, speciogynine pseudoindoxyl. The characteristic spiro-5-5-6 tricyclic system of these alkaloids is formed via a protecting group-free cascade relay process in which oxidized tryptamine and secologanin analogs are used. Furthermore, we uncovered that mitragynine pseudoindoxyl exists and acts not as a single molecular entity but as a dynamic ensemble of stereoisomers in protic environments, thus, it exhibits structural plasticity in biological systems. Accordingly, these synthetic, structural, and biological studies provide a basis for the planned design of mitragynine pseudoindoxyl analogs, which can guide the development of next-generation analgesics.
Selective profiling of carboxylic acid in crude oil by halogen-labeling combined with liquid chromatography and high-resolution mass spectrometry
Authors: Huynh Khoa , Feilberg Karen , Sundberg Jonas
Published: February 2023

Carboxylic acids are a small but important compound class within petroleum chemistry, contributing significantly to the behavior of crude oil, e.g., in production, processing, and its environmental impact. A more detailed structural information is fundamental to improve our understanding of their influence on petroleum properties. However, due to matrix effects, structural diversity and low abundance, selective characterization of carboxylic acids in crude oil remains challenging. In this work, we present a new methodology for profiling such compounds by liquid-liquid extraction and selective derivatization using 4-bromo-N-methylbenzylamine (4-BNMA) followed by liquid chromatography and electrospray ionization Orbitrap high-resolution mass spectrometry (LC-ESI-Orbitrap HRMS). The fragmentation of 4-BNMA derivatives produces a pair of unique product ions, m/z 169 and 171, which enables the identification of chromatographic sections containing carboxylic acids. The mass spectra of these fractions are extracted, with the acids further computationally isolated based on the unique isotope pattern from the incorporated bromine atom. The method was optimized and validated using seven acid standards and designs of experiments (DOEs), assuring robustness and sensitivity for non-target screening purposes. This method successfully detected up to 380 carboxylic acids in six Danish North Sea crude oil, with up to two carboxyl groups and other heteroatom functionalities. The results indicated that the most populated species are fatty acids (double bond equivalents, DBE, = 1) and naphthenic acids (DBE = 2 6). Besides classical carboxylic acids detected, we observed other acids containing multiple functional groups with nitrogen, oxygen, and sulfur atoms.

Cellular membrane lipid composition is implicated in diseases and major biological functions in cells, but membranes are difficult to study experimentally due to their intrinsic disorder and complex phase behaviour. Molecular dynamics (MD) simulations have been useful in understanding membrane systems, but they require significant computational resources and often suffer inaccuracies in model parameters. Applications of data-driven and machine learning methods, currently revolutionising many fields, are limited to membrane systems due to the lack of suitable training sets. Here we present the NMRlipids Databank---a community-driven, open-for-all database featuring programmatic access to quality evaluated atom-resolution MD simulations of lipid bilayers. The NMRlipids databank will benefit scientists in different disciplines by providing automatic ranking of simulations based on their quality against experiments, flexible implementations of data-driven and machine learning applications, and rapid access to simulation data via graphical user interface. To demonstrate the unlocked possibilities beyond current MD simulation studies, we analyzed how anisotropic diffusion of water and cholesterol flip-flop rates depend on membrane properties.

A User-friendly Graphical User Interface for Dynamic Light Scattering Data Analysis
Authors: Salazar Matthew , Srivastav Harsh , Srivastava Abhishek , Srivastava Samanvaya
Published: February 2023

Dynamic light scattering (DLS) is a commonly used analytical tool for characterizing the size distribution of colloids in a dispersion or a solution. Typically, the intensity of a scattering produced from the sample at a fixed angle from an incident laser beam is recorded as a function of time and converted into time autocorrelation data, which can be inverted to estimate the distribution of colloid diffusivity to estimate the colloid size distribution. For polydisperse samples, this inversion problem, being a Fredholm integral equation of the first kind, is ill-posed and is typically handled using cumulant expansions or regularization methods. Here, we introduce a user-friendly graphical user interface (GUI) for analyzing the measured scattering intensity time autocorrelation data using both the cumulant expansion method and regularization methods, with the latter implemented using various commonly employed algorithms including NNLS, CONTIN, REPES, and DYNALS. Additionally, the GUI also enables a comparison of the size distributions generated by various algorithms and an evaluation of their performance. We present the fit results obtained from the GUI for model monomodal and bimodal dispersions to highlight the strengths, limitations, and scope of applicability of these algorithms for analyzing time autocorrelation data from DLS.
Multi-level interaction between HIF and AHR transcriptional pathways in kidney carcinoma
Authors: Lafleur Véronique N , Halim Silvia , Choudhry Hani , Ratcliffe Peter J , Mole David R
Published: February 2023

Hypoxia-inducible factor (HIF) and aryl hydrocarbon receptor (AHR) are members of the bHLH-PAS family of transcription factors that underpin cellular responses to oxygen and to endogenous and exogenous ligands, respectively, and have central roles in the pathogenesis of renal cancer. Composed of heterodimers, they share a common HIF-1β/ARNT subunit and similar DNA-binding motifs, raising the possibility of crosstalk between the two transcriptional pathways. Here, we identify both general and locus-specific mechanisms of interaction between HIF and AHR that act both antagonistically and cooperatively. Specifically, we observe competition for the common HIF-1β/ARNT subunit, in cis synergy for chromatin binding, and overlap in their transcriptional targets. Recently, both HIF and AHR inhibitors have been developed for the treatment of solid tumours. However, inhibition of one pathway may promote the oncogenic effects of the other. Therefore, our work raises important questions as to whether combination therapy targeting both of these pro-tumourigenic pathways might show greater efficacy than targeting each system independently.

Personalized Injury Reduction Strategies in Sports Medicine: Lessons Learned from Advances in Breast Cancer Treatment: A Clinical Commentary
Authors: Bullock Garrett , Collins Gary , Adams Rober , Thigpen Charles , Shanley Ellen
Published: February 2023

Background

Injury rates across sport have risen over the past twenty years, despite increased efforts in training and injury prevention. The rise in injury rates suggest that current approaches to estimating injury risk and risk management are not effective. One factor limiting progress is the inconsistency in screening, risk assessment, and risk management strategies to guide injury mitigation approaches.

Clinical Question

How can sports physical therapists identify and apply lessons learned from other healthcare fields to improve athlete injury risk and risk management strategies?

Key Results

Breast cancer mortality has consistently decreased over the last 30 years, largely attributed to advances in personalizing the prevention and treatment strategies which include modifiable and non-modifiable factors when assessing risk, the transition to personalized medicine, and the systematic approach used to investigate individual risk factors. Three critical phases have facilitated the identification and importance of individual risk factors and developing targeted, personalized strategies for breast cancer risk including: 1) Establishing the potential relationship between factors and outcomes; 2) Prospectively investigate the strength and direction of the relationship; 3) Investigating if intervening on identified factors alters prognosis.

Clinical Application

Applying lessons learned from other healthcare fields could improve shared decision making between the clinician and athlete concerning risk assessment and management. Examples include calculating only non-modifiable risk, creating individualized screening schedules based on risk assessment, or calculating the influence of each intervention on the athlete’s injury risk. A systematic approach to identify and intervene on risk is needed to improve athlete outcomes.
The “Mother Load” and Return to Sport: A Case Report of Returning to Professional Netball Following Cesarean Section
Authors: Diggles Alexandra
Published: February 2023

Background

Increasing numbers of elite female athletes are competing in professional sport, and many wish to become pregnant and return to competitive sport after childbirth. Athletes have a higher risk of pelvic floor dysfunction (PFD) than non-athletes (54% versus 7%) and there is also an increased prevalence in post-partum women compared to nulliparous women (35% versus 2.8-7.9%). Additionally, PFD has been shown to influence athletic performance. High quality evidence for elite athletes is lacking, and there are no exercise guidelines specifically for these women to prepare or effectively guide their safe return to sport (RTS). The purpose of this case report is to detail the management of an elite athlete who presented following cesarean section (CS) with the goal of RTS within 16 weeks.

Case Description

A 27-year-old primiparous Caucasian professional netballer presented at four weeks post- caesarean section (CS) for RTS screening and assessment of pelvic floor muscle (PFM) function. Assessment included readiness and fear of movement screening, dynamic pelvic floor muscle function, structural integrity of the CS wound, levator hiatal dimensions, bladder neck descent, and early global neuromuscular screening. Measures were collected at four weeks, eight weeks, and six months post-partum. The post-partum athlete demonstrated alterations in pelvic floor muscle function, reduced lower limb power and psychological readiness. A functionally staged dynamic and sport specific pelvic floor muscle training program was implemented and adapted to the patient for her early post-partum timeline.

Results

Rehabilitation strategies were effective in achieving the primary outcome of RTS at 16 weeks post-partum with no adverse events reported at 6 months follow-up.

Discussion

This case highlights the need for a holistic and individualised RTS management approach that includes women’s and pelvic health risk factors in a professional athlete.

Authors: Escamilla Rafael F
Published: February 2023

This clinical commentary will address five key concepts that can be used by clinicians as criteria for selecting lower extremity weight bearing exercises (WBE) and non-weight bearing exercises (NWBE) employed for cruciate ligament and patellofemoral rehabilitation. The following will be discussed for both cruciate ligament and patellofemoral rehabilitation: 1) Knee loading varies between WBE and NWBE; 2) Knee loading varies with technique variations within WBE and NWBE; 3) Knee loading varies between different WBE; 4) Knee loading varies as a function of knee angle; and 5) Knee loading increases with increased knee anterior translation beyond toes.
Survey on Knowledge, Use, and Diagnostic Applicability of Special Tests for Rotator Cuff Involvement in Clinical Practice
Authors: Forbush Steven W. , Bandy William D. , Back-Kremers Gabrielle L. , Renfroe Mollie , Downey Haley F.
Published: February 2023

Background

Recently, researchers have commented that shoulder special tests cannot identify the structure causing rotator cuff symptoms and should only be considered pain provocation tests. Others have disagreed, reporting that special tests were able to accurately detect the presence of rotator cuff involvement.

Purpose

The purpose of this study was to determine the knowledge, use, and perceived effectiveness of 15 selected special tests utilized to examine patients with possible rotator cuff dysfunction.

Study Design

Descriptive study using survey.

Methods

An electronic survey was returned by 346 members of the Academies of Orthopedic and Sports Physical Therapy through list serves. Descriptions and pictures for 15 special tests of the shoulder were included in the survey. Information regarding years of clinical experience and American Board of Physical Therapy Specialties (ABPTS) specialist certification in Sports or Orthopedics was collected. Respondents were asked if they could identify and use the special tests to evaluate dysfunction of the rotator cuff - and how confident they were in ability of the tests to diagnose dysfunction of the rotator cuff.

Results

The four tests most readily known by respondents included the empty can, drop arm, full can, and Gerber’s tests, and the four tests used regularly by the respondents included the infraspinatus, full can, supraspinatus, and champagne toast tests. The infraspinatus, champagne toast, external rotation lag (ERLS), and the belly-off tests were found to be the be most useful for establishing a diagnosis of the muscle-tendon complex involved. Years of experience and clinical specialization was not relevant to knowledge or use or these tests.

Conclusions

This study will allow clinicians and educators to understand which special tests are easily identified, regularly used, and perceived as helpful for the diagnosis of muscles involved in a rotator cuff dysfunction.

The Need To Change Return to Play Testing in Athletes Following ACL Injury: A Theoretical Model
Authors: Wilk Kevin E , Thomas Zachary M , Arrigo Christopher A , Davies George J
Published: February 2023

The incidence of knee injuries in sport, particularly involving the ACL, appears to be increasing yearly, especially in younger age athletes. Even more concerning is the frequency of ACL reinjury also appears to be increasing year after year. Improving the objective criteria and testing methods used to determine return to play (RTP) readiness following ACL surgery is one aspect of the rehabilitation process that can significantly help in reducing reinjury rates. Currently, the majority of clinicians are still using post operative time frames as their number one criterion for clearance to RTP. This flawed method demonstrates an inadequate reflection of the true unpredictable, dynamic environment athletes are returning to participate in. In our clinical experience, objective testing to allow for clearance to sport participation following an ACL injury should incorporate neurocognitive and reactive testing due to the nature of the injury typically occurs because of failed control of unanticipated reactive movements. The purpose of this manuscript is to share a neurocognitive testing sequence we currently employ consisting of 8 tests in 3 categories: Blazepod tests, reactive shuttle run tests, and reactive hop tests. The use of a more dynamic reactive testing battery may decrease the reinjury rates when an athlete is cleared for participation by measuring readiness in chaotic circumstances that are more truly reflective of the sporting environment the athlete is working to return to and in the process give them a greater sense of confidence.
Are Exercise Therapy Protocols For The Treatment of Hip-Related Pain Adequately Described? A Systematic Review of Intervention Descriptions
Authors: Estberger August , Kemp Joanne L , Thorborg Kristian , Pålsson Anders , Ageberg Eva
Published: February 2023

Background

Hip-related pain is an umbrella term encompassing pain from non-arthritic hip joint pathologies, such as femoroacetabular impingement syndrome, hip dysplasia, and labral tears. Exercise therapy is commonly recommended for these conditions, but the reporting completeness of these interventions is currently unclear.

Purpose

The aim of this systematic review was to assess the reporting completeness of exercise therapy protocols for people with hip-related pain.

Study design

Systematic review according to PRISMA guidelines.

Materials and Methods

A systematic search was conducted, searching the MEDLINE, CINAHL, and Cochrane databases. The search results were independently screened by two researchers. Inclusion criteria were studies using exercise therapy in people with non-arthritic hip-related pain. Two independent researchers used the Cochrane risk of bias tool version 2 to analyze risk of bias, and the Consensus on Exercise Reporting Template (CERT) checklist and score (1-19) to synthesize reporting completeness.

Results

Fifty-two studies used exercise therapy for hip-related pain, but only 23 were included in the synthesis as 29 studies had no description of the intervention. CERT scores ranged from 1 to 17 (median 12, IQR 5-15). The most well-described items were tailoring (87%), and the least well-described items were motivation strategies (9%) and starting level (13%). Studies used exercise therapy alone (n=13), or in combination with hip arthroscopy (n=10).

Conclusion

Only 23 of 52 eligible studies reported sufficient details to be included in the CERT synthesis. The median CERT score was 12 (IQR 5-15), with no study reaching the maximum score of 19. Lack of reporting makes it difficult to replicate interventions in future research, and to draw conclusions on efficacy and dose-response to exercise therapy for hip-related pain.

Flexor-Pronator Mass Training Exercises Selectively Activate Forearm Musculature
Authors: Fukunaga Takumi , Fedge Connor , Tyler Timothy , Mullaney Michael , Schmitt Brandon , Orishimo Karl , McHugh Malachy , Nicholas Stephen
Published: February 2023

Purpose/Hypothesis

The flexor-pronator mass of the forearm contributes dynamic stability to the medial elbow. Training this muscle group is essential for overhead athletes, however, there is lack of evidence supporting use of training exercises. The purpose of this study was to measure the extent of EMG activity of the flexor pronator musculature during two distinct forearm strengthening exercises using resistance bands. It was hypothesized that two exercises would elicit at least moderate level of muscle activity, but the activation would be different in the pronator versus the flexor muscles.

Materials/Methods

10 healthy subjects (all males, age 36±12 years) were included. Surface EMG activity was measured on three muscles of the dominant-side forearm: flexor carpi ulnaris (FCP), flexor digitorum superficialis (FDS), and pronator teres (PT). After measurement of maximal voluntary contraction (MVC) for each muscle, subjects performed wrist ulnar deviation and forearm pronation exercises using elastic band resistance. Resistance was set to elicit moderate exertion (5/10 on the Borg CR10 scale). Order of exercise was randomized and three repetitions of each exercise were performed. Mean peak EMG activity in each muscle across repetitions during the eccentric phase of each exercise was calculated and expressed as a percentage of MVC. Moderate level of activity was defined as 21% of MVC or higher. Peak normalized EMG activity in each muscle was compared using two-way (exercise x muscle) repeated-measures ANOVA with post-hoc pairwise comparisons if a significant interaction was found.

Results

There was an exercise by muscle interaction effect (p<0.001). The ulnar deviation exercise selectively activated FCU (40.3%) versus FDS (19.5%, p=0.009) and PT (21.5%, p=0.022). Conversely, the pronation exercise selectively activated FDS (63.8%, p=0.002) and PT (73.0%, p=0.001) versus FDS (27.4%).

Conclusion

The ulnar deviation and pronation exercises using elastic band resistance studied targeted and activated the flexor-pronator mass musculature. The ulnar deviation and pronation exercises using elastic band resistance are practical and effective means of training the flexor-pronator mass. These exercises can be readily prescribed to athletes and patients as part of their arm care program.
The Use of MSK Ultrasound with Quadriceps Muscle Injury
Authors: Manske Robert C , Voight Michael , Wolfe Chris , Page Phil
Published: February 2023

Quadriceps muscle injury is a common occurrence, especially among athletes. While a careful history and a thorough physical examination are important steps in the assessment of quadriceps muscle pathology, it is still difficult to differentiate the type and severity of the pathology. Because of this difficulty, musculoskeletal ultrasound (MSK-US) is an invaluable tool in the diagnosis of quadriceps muscle or tendon injury. Utilizing this noninvasive imaging technique, medical professionals can easily diagnose and monitor muscle and tendon disorders to quickly determine the correct treatment plan for each individual case. The ability to view these structures in real-time allows identification of any present pathologies. MSK-US has become a useful component in diagnosing quadriceps muscle and tendon injuries due to its ability to clearly display the affected structures without exposing the patient to radiation or utilizing ionized contrast media. MSK-US provides valuable insight into fluid dynamics around joints and can even detect myotendinous tears that might otherwise be overlooked with the clinical examination or symptoms usually reported by patients. MSK-US can provide precise visualization of edema and can easily distinguish between benign and potentially pathological findings which make it an integral part of any holistic evaluation of quadriceps muscle and tendon injury. Additionally, it can be used to track the progress of physical therapy treatments and monitor tissue healing. This information is invaluable in ensuring an optimal outcome for any quadriceps muscle and tendon injury. Therefore, when used in combination with clinical tests, MSK-US can drastically increase the accuracy of the clinical examination. By utilizing this technology, healthcare practitioners have reliable access to more comprehensive diagnostics for musculoskeletal injuries and diseases than ever before. Clinicians are then able to tailor rehabilitation plans more effectively and ensure their patients receive proper treatment. As a result, recovery times may be shortened, and patients are able to return to their normal activities more quickly.

Este artículo muestra los resultados de un estudio de caso centrado en la puesta en marcha de un programa didáctico en un centro de primaria. El programa constó de dos actuaciones didácticas distintas en dos períodos de prácticum de magisterio. La primera se realizó con 2 grupos de 6º durante 5 sesiones y la segunda con 2 grupos de 5º durante 4 sesiones. Participaron 53 estudiantes. El tema escogido fue la Guerra Civil. Se combinaron conocimientos y emociones. De las observaciones de la docente en prácticas, así como del análisis temático realizado sobre las intervenciones y producciones del alumnado, se evidencia cómo la simbiosis entre una educación patrimonial crítica, asentada sobre la memoria como forma de entender el paisaje, y la realización de salidas contextualizadas al entorno, refuerzan en el alumnado destrezas cívico-sociales.

This study aimed to determine the effectiveness of the “engage, study, activate” (ESA) approach using interactive technological tools at a private university in southern Ecuador. The participants were 67 undergraduate and postgraduate students enrolled in two English as a foreign language (EFL) programs. The study was conducted over a period of ten weeks in three different courses, in which the ESA approach was implemented in an online remote learning environment due to the Covid 19 pandemic. The research instruments included an online diagnostic questionnaire, an observation checklist, an online perceptions questionnaire, and semi-structured interview. In each stage of the ESA approach, activities focusing on developing students’ knowledge were designed using interactive technological tools such as Zoom, Canvas, Quizizz, Canva, and Padlet. The results show that in the engage stage, participants felt comfortable, relaxed, and motivated about learning something new. In addition, dialogues and groupwork were the favorite activities during the study stage, where participants shared their ideas with one another. The use of ICT tools was especially effective in the activate stage, because it allowed participants to work collaboratively and receive feedback. All the stages of the ESA approach helped the participants improve their linguistic and pedagogical skills since the use of technological tools allowed them to be actively involved in the learning process.
