Published: August 2022

<span lang="EN-US">This case study investigated the phenomenon of English as a foreign language (EFL) teachers’ perceptions of professional development (PD) related to language proficiency, which has become a critical issue in the field of EFL teaching and has played an important role in facilitating students to learn English well. Interview guides were employed as the main instrument to elicit information about PD activities related to language proficiency maintenance and improvement, comprising closed-ended and open-ended items. The participants of the study were six professional EFL teachers who have had 5 to 30 years of teaching experience, selected from high schools in a capital city in Indonesia. Data were analyzed descriptively to result in frequencies of importance levels and qualitatively to explore patterns of PD activities. The results showed that two factors affecting the participants’ acknowledgement of the importance of language proficiency PD activities: the need to maintain and improve language proficiency and the benefits of proficiency for teaching and learning. It is recommended that Indonesian EFL teachers develop self-awareness of the importance of improving their skills not only pedagogically but also professionally and realize that PD for language proficiency in particular is imperative to help them keep their professionalism high. </span>

Abstract
This article recovers Resource One, an “alternative” computer-resource center founded in San Francisco in 1971 and celebrated by Whole Earth Catalog–founder Stewart Brand as a “counter-computer” initiative in his 1972 Rolling Stone article “Spacewar: Fanatic Life and Symbolic Death Among the Computer Bums.” Departing from the usual mythologizing of personal computing often linked to Brand's rhetoric of “access to tools,” this reading re-situates Resource One in the urban commune where it was located, Project One. Optic Nerve's video documentary about the communards' life there, Project One (1972), serves as both archive and interpretation of the commune, helping to demonstrate the economic and political utility of the ambivalence harbored within the notion of participation and the ethos of do-it-yourself. The essay ties the logic of participation to the emergence of a new topology of material and informatic domains as well as to novel configurations of home and work. It does so to trace forms of subjectivity that were then being forged through computerization in the service of a postindustrial economy.

Published: August 2022

Background and Objectives: Performing an effective maxillary antrostomy is critical to improving chronic maxillary sinusitis symptomatology. Incomplete dissection of the uncinate process and failure to incorporate the natural drainage pathway may lead to recirculation and need for revision surgery. The purpose of this study is to determine if 70° endoscopes provide added value in determining incomplete dissection or residual disease. Methods: Prospective study of 35 sinuses from 18 patients undergoing FESS for Chronic Rhinosinusitis (CRS) between 11/1/2020 and 4/30/2021. Two fellowship trained Rhinologists initially performed maxillary antrostomies exclusively using a 0° endoscope, then transitioned to a 70° endoscope. Surgeons completed a survey to assess completion of the antrostomy prior to use of 70° endoscope, sino-nasal anatomy, and difficulty of the operation. Intraoperative photographs before and after using a 70° endoscope were evaluated by a third party. Pre-operative CT scans were used to evaluate the sphenoid keel-caudal septum-nasolacrimal duct (SK-CS-NL) angle. Results: Of 35 sinuses from 18 patients all 35 sinuses had CRS with 48.5% having nasal polyposis and 42.9% having active infection. There was residual inflammatory tissue in the anterior maxillary sinus, including polypoid tissue and uncinate process prior to using the 70° endoscope in 82.9% of sinuses. The natural drainage pathway was not incorporated into the dissection in 28.6% of sinuses before converting to 70° endoscope. Incomplete dissection with 0° endoscope was not associated with nasal polyposis ( P = .086) or uncinate position (0.741). Narrow SK-CS-NL angles were associated with incomplete dissection of the anterior maxillary sinus with 0° endoscope (16.0° ± 3.0° vs 20.6° ± 3.2°; P = .013). Conclusion: Use of 70° endoscope in maxillary antrostomy may be beneficial in identifying and resecting disease within the anterior maxillary sinus that may otherwise be difficult to find using a 0° endoscope. This is especially true in patients with narrow nasolacrimal duct positioning.

Published: August 2022

GFRP composites experience structural changes like matrix cracking, debonding, delamination, and fibre failure on static and dynamic loading. In this work, composites with varying fibre orientation interaction angle and volume fractions are prepared and exposed to cyclic load. The cyclic load (R = 0) is a constant amplitude flexural load imposed on the cantilever beam specimen with varying frequencies (2.6, 4.6, 8.6 Hz) and cycles (up to 44 × 103). The structural integrity of the specimens on loading is examined in terms of Flexural, modulus, Acoustic Emission (AE) and heat transfer changes. The drop in flexural modulus is minimum in higher Vf = 32% laminate (A1 = 7.01%, B1 = 1.86%) than the lower Vf = 25% (A2 = 19.86%, B2 = 8.6%). The observed AE peak frequency for the induced damages is in the range of 50–100, 110–230, 245–380 kHz. The drop-in fibre volume fraction has a significant role in laminate with lower fibre interaction (Type A) to offer minimum variation (5.25%) in AE activity count which is the opposite in laminates with higher fibre interaction angle (31.75%). The step heat thermography exhibits minimum temperature difference (∆T) for moderate loading frequency and in a few cases, ∆T drops well below the virgin, insisting on in situ thermography to study the dynamic changes in composites. A fibre dominant behaviour can be observed with minimum variation in AE activity in a lower fibre interaction angle. Thus, the fibre orientation angle and fibre volume fraction have a significant role in the retention of the structural integrity of composites in dynamic loading.

Published: August 2022

Objective To identify the most frequent causes of secondary pseudotumor cerebri syndrome and compare phenotype, clinical presentation, and symptoms of secondary pseudotumor cerebri syndrome to the primary form of pseudotumor cerebri syndrome, idiopathic intracranial hypertension. Methods The study was a prospective cohort study including patients with new-onset pseudotumor cerebri syndrome. Diagnostic work up was standardized. Patients were diagnosed with secondary pseudotumor cerebri syndrome or idiopathic intracranial hypertension according to the revised Friedman criteria. Secondary pseudotumor cerebri syndrome patients were categorized into five causes: medication, systemic causes, sleep apnea, cerebrovascular causes, and several competing causes. Phenotype, clinical presentation, symptoms and neuroimaging were compared between groups. Results Out of 278 cases, 28 secondary pseudotumor cerebri syndrome and 120 idiopathic intracranial hypertension patients were included. The most frequent causes of secondary pseudotumor cerebri syndrome were medication (n  =  8, 28.6%) and systemic causes (n = 8, 28.6%), followed by sleep apnea (n = 5, 17.9%), cerebrovascular causes (n = 4, 14.3%) and several competing causes (n = 3, 10.7%). Secondary pseudotumor cerebri syndrome and idiopathic intracranial hypertension patients were phenotypically alike and predominately female, premenopausal, and obese. Symptoms and objective findings at disease onset were similar between groups. Conclusion Secondary pseudotumor cerebri syndrome should be considered in all patients with suspected pseudotumor cerebri syndrome as secondary pseudotumor cerebri syndrome and idiopathic intracranial hypertension patients are phenotypically and clinically alike. A thorough diagnostic workup is needed as treatment of idiopathic intracranial hypertension and secondary pseudotumor cerebri syndrome is markedly different.

Published: August 2022

Background: Active-duty servicemembers are a population at risk for the development of posterior shoulder instability. While short-term outcomes after arthroscopic posterior labral repair for posterior shoulder instability are promising, there is a paucity of longer term follow-up data for this procedure. Purposes: The primary purpose was to report midterm outcomes after arthroscopic posterior labral repair in active-duty military patients for posterior shoulder instability without bone loss. The secondary purpose was to determine if outcomes varied between anchor types used. Study Design: Cohort study; Level of evidence, 3. Methods: Preoperative and postoperative outcomes, with a minimum 3-year follow-up, for a visual analog scale for pain, the Single Assessment Numeric Evaluation (SANE), the American Shoulder and Elbow Surgeons (ASES) score, and the Rowe score were collected and analyzed. A separate subgroup analysis was performed comparing the outcomes of patients who underwent repair with biocomposite anchors versus those who underwent repair with all-suture anchors. Results: A total of 73 patients with a mean follow-up of 82.55 ± 24.20 months met the inclusion criteria and were available for analysis. As a whole, the cohort demonstrated statistically and clinically significant improvements in outcome scores at final follow-up. Preoperative and postoperative range of motion did not vary significantly. While the difference in final outcome scores between the 2 anchor types did not reach statistical significance, a statistically significantly larger proportion of patients who underwent repair with all-suture anchors versus those who underwent repair with biocomposite anchors met the Patient Acceptable Symptom State for the SANE (97.14% vs 78.95%, respectively; P = .0180) and the ASES score (88.57% vs 68.42%, respectively; P = .0171). The proportion of patients who achieved the substantial clinical benefit or surpassed the minimal clinically important difference, however, did not vary by anchor type. Overall, 70 patients (95.89%) remained on active duty and were able to return to preinjury work and recreational activity levels. There were 3 patients (4.11%) who had recurrent posterior instability. Conclusion: This population of active-duty servicemembers undergoing posterior labral repair for posterior labral instability without bone loss demonstrated a statistically and clinically significant improvement in midterm outcomes, a low recurrence rate, and a rate of return to active duty of 95.89%, regardless of the anchor type used.

Published: August 2022

Background:Injury risk prediction is an emerging field in which more research is needed to recognize the best practices for accurate injury risk assessment. Important issues related to predictive machine learning need to be considered, for example, to avoid overinterpreting the observed prediction performance.Purpose:To carefully investigate the predictive potential of multiple predictive machine learning methods on a large set of risk factor data for anterior cruciate ligament (ACL) injury; the proposed approach takes into account the effect of chance and random variations in prediction performance.Study Design:Case-control study; Level of evidence, 3.Methods:The authors used 3-dimensional motion analysis and physical data collected from 791 female elite handball and soccer players. Four common classifiers were used to predict ACL injuries (n = 60). Area under the receiver operating characteristic curve (AUC-ROC) averaged across 100 cross-validation runs (mean AUC-ROC) was used as a performance metric. Results were confirmed with repeated permutation tests (paired Wilcoxon signed-rank-test; P < .05). Additionally, the effect of the most common class imbalance handling techniques was evaluated.Results:For the best classifier (linear support vector machine), the mean AUC-ROC was 0.63. Regardless of the classifier, the results were significantly better than chance, confirming the predictive ability of the data and methods used. AUC-ROC values varied substantially across repetitions and methods (0.51-0.69). Class imbalance handling did not improve the results.Conclusion:The authors’ approach and data showed statistically significant predictive ability, indicating that there exists information in this prospective data set that may be valuable for understanding injury causation. However, the predictive ability remained low from the perspective of clinical assessment, suggesting that included variables cannot be used for ACL prediction in practice.

Published: August 2022

Background: Massive rotator cuff tears have a high incidence of postoperative retear that can reach 90%. It is still unclear which intervention may reduce the incidence of retear and improve the functional and clinical outcomes. Purpose/Hypothesis: The purpose of this study was to investigate the clinical and structural outcomes at 2 years after repair of reparable massive rotator cuff tears with and without the use of partial superior capsular reconstruction (pSCR), using the autologous long head of the biceps tendon (LHBT) as a graft. It was hypothesized that augmentation with a pSCR would decrease retear rates. Study Design: Cohort study; Level of evidence, 3. Methods: The authors compared arthroscopic repair of massive posterosuperior rotator cuff tears with and without augmentation using the LHBT for pSCR between 2015 and 2017. After applying the selection criteria, 106 patients were included in the study and distributed into 2 groups of 50 and 56 patients. Patients in the first group (50 patients) underwent arthroscopic repair without use of the LHBT (AR group), and patients in the second group (56 patients) underwent arthroscopic repair with use of the LHBT for pSCR (AR-LHBT group). The structural outcome was evaluated by ultrasound at 2 years of follow-up. Function and pain were evaluated preoperatively and at the 2-year follow-up using the American Shoulder and Elbow Surgeons (ASES) score and visual analog scale (VAS). Pre- and postoperative active range of motion, including forward elevation, external rotation, and abduction, were also documented. Results: No significant differences were found between groups regarding the baseline characteristics. After 24 months, both groups showed significant improvement from preoperative ASES scores, VAS score, and active range of motion ( P < .01 for all). Patients in the AR-LHBT group showed significant improvements in postoperative functional and pain scores compared with the AR group in all measurements at the 2-year follow-up (ASES score: 77.23 ± 7.45 vs 71.04 ± 9.28, P < .01; VAS score: 1.64 ± 1.03 vs 2.12 ± 1.06, P < .01). Final range of motion was significantly increased for the AR-LHBT group for forward elevation (155 [interquartile range {IQR}, 150-160] vs 150 [IQR, 140-170]; P < .01) and abduction (150 [IQR, 140-157.5] vs 120 [IQR, 100-140]; P < .01), but external rotation was significantly greater for the AR group (54.43 ± 10.55 vs 59.5 ± 10.55; P < .01). Postoperative ultrasonography at the 2-year follow-up revealed a higher retear rate in the AR group than in the AR-LHBT group (46% vs 14%; P < .01). Conclusion: Use of the LHBT for pSCR to augment massive rotator cuff tears resulted in markedly lower retear rates and modestly improved pain and function outcomes compared with repair alone.

Background: Although posterior glenohumeral instability is becoming an increasingly recognized cause of shoulder pain, the role of posterior glenoid bone loss on outcomes remains incompletely understood. Purposes: To prospectively determine the amount of bone loss associated with posterior instability events and to determine predisposing factors based on preinstability imaging. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 1428 shoulders were evaluated prospectively for ≥4 years. At baseline, a subjective history of shoulder instability was ascertained for each patient, and bilateral noncontrast magnetic resonance imaging (MRI) scans of the shoulders were obtained regardless of any reported history of shoulder instability. The cohort was prospectively followed during the study period, and those who were diagnosed with posterior glenohumeral instability were identified. Postinjury MRI scans were obtained and compared with the screening MRI scans. Glenoid version, perfect-circle-based bone loss was measured for each patient's pre- and postinjury MRI scans using previously described methods. Results: Of the 1428 shoulders that were prospectively followed, 10 shoulders sustained a first-time posterior instability event and 3 shoulders sustained a recurrent posterior instability event. At baseline, 11 of 13 shoulders had some amount of glenoid dysplasia and/or bone loss. The change in glenoid bone loss was 5.4% along the axis of greatest loss (95% CI, 3.8%-7.0%; P = .009), 4.4% at the glenoid equator (95% CI, 2.7%-6.2%; P = .016), and 4.2% of total glenoid area (95% CI, 2.9%-5.3%; P = .002). Recurrent glenoid instability was associated with a greater amount of absolute bone loss along the axis of greatest loss compared with first-time instability (recurrent: 16.8% ± 1.1%; 95% CI, 14.6%-18.9%; first-time: 10.0% ± 1.5%; 95% CI, 7.0%-13.0%; P = .005). Baseline glenoid retroversion ≥10° was associated with a significantly greater percentage of bone loss along the axis of greatest loss (≥10° of retroversion: 13.5% ± 2.0%; 95% CI, 9.6%-17.4%; <10° of retroversion: 8.5% ± 0.8%; 95% CI, 7.0%-10.0%; P = .045). Conclusions: Posterior glenohumeral instability events were associated with glenoid bone loss of 5%. The amount of glenoid bone loss after a recurrent posterior glenohumeral instability event was greater than that after first-time instability. Glenoid retroversion ≥10° was associated with a greater amount of posterior glenoid bone loss after a posterior instability event.

Objectives: Placental tissue is an established biomaterial used in many clinical applications. However, its use for tissue engineering purposes has not been fully realized. Though articular cartilage extracellular matrix (ECM)-derived oriented scaffolds for cartilage tissue engineering were developed, resources are a hindrance to its application. In this regard, the present study investigated the feasibility of using intact decellularized human umbilical cord Wharton’s jelly (hUC-WJ) as a new material for chondrocyte carrier in cartilage tissue engineering. The developed hUC-WJ scaffold provides a good microenvironment for the attachment, viability, and delivery of seeded human autologous chondrocytes. It has an advantage over other biomaterials in terms of abundant availability and similar biochemistry to cartilage ECM. Materials and methods: hUC-WJ obtained from fresh human placenta were decellularized and gamma sterilized. Human cartilage tissue was obtained from the patients with a total knee replacement. The chondrocytes were isolated and expanded in-vitro and seeded onto the hUC-WJ scaffold. The efficiency of the decellularized tissue as a delivery system for human cartilage cells was investigated by histology, immunohistochemistry, cell count, flow cytometry, and scanning electron microscopy (SEM). Results: The results showed that the decellularized hUC-WJ scaffold has supported the microenvironment for chondrocyte attachment and viability without losing its phenotype. In addition, the cells were spread through the hUC-WJ scaffold as confirmed by histology and SEM. Conclusion: Based on obtained results, the hUC-WJ scaffold has great potential as a 3D scaffold for human autologous chondrocyte carriers in tissue engineering and regenerative medicine applications.
