Khoza-Shangase, Katijah
- Abstract
The academic landscape is fraught with challenges, particularly for scholars whose identities intersect with marginalised backgrounds. This reflective paper explores the nuanced implications of revisions, corrections or rejections (RCRs) on the academic journey of a Black isiZulu-speaking African woman scholar in Audiology from South Africa. It contends that the effects of RCRs extend beyond the confines of a single manuscript, impacting the scholar’s sense of self, existence within the academic realm, and the deliberate ‘cancelling’ of one’s knowledge. Focusing on the unique challenges faced by African scholars, particularly the perceived emphasis on publishing as a measure of belonging, the paper employs a benefit-risk evaluation lens. This approach delves into the complex interaction between personal and environmental factors, shedding light on the multifaceted considerations that African scholars grapple with to establish their presence within the academic sphere. The paper outlines the well-known ‘publish or perish’ phenomenon, emphasising the hypercompetitive nature of the academic and research environment. Peer review, considered a critical component in the publication process, is explored for its role in quality assurance. However, the paper contends that the peer review process can inadvertently perpetuate inequalities, especially for scholars from underrepresented backgrounds. Thematic analysis of reviewer reports from papers I recently submitted forms the core of the paper. Seven emergent themes, such as the influence of proximity to native English speakers and the dominance of Western narratives, illustrate the challenges I faced in both local and international journals. Notably, the paper provides direct quotes exemplifying each theme, offering a very personalised perspective on the adversities encountered during the publication journey. The paper situates the field of audiology within the broader context of institutional and systemic racism, highlighting the underrepresentation of certain racial groups within the profession. It argues that this underrepresentation extends to knowledge generation and publishing, perpetuating the normalisation of Euro-American-centric norms and the exoticisation of Afrocentric standards. The reflective paper concludes by asserting that epistemological racism, intertwined with individual and institutional racism, stifles my pursuit of decolonisation and Africanisation of speech-language and hearing knowledge and practice. It contends that the peer review process, often Euro-American-centric, contributes to the silencing and exclusion of diverse knowledges, hindering local knowledge development and intellectual practices. In navigating the academic minefield, the paper calls for a re-evaluation of existing norms and practices within the peer review process to create a more inclusive and equitable academic environment for scholars with diverse backgrounds.

- Abstract
Intraoperative calcar fractures (IOCFs) are an established complication of cementless total hip arthroplasty (THA). Prompt recognition and management may prevent subsequent postoperative complications. This study aimed to evaluate the outcomes and revision rates of THAs with IOCFs identified and managed intraoperatively. There were 11,438 primary cementless THAs performed at a single institution from 2009 to 2022. Prospectively collected data on cases with an IOCF was compared to cases without the complication. The fracture group had a lower body mass index (26.9 versus 28.9 kg/m
2 ; P =.01). Patient age, sex, and mean follow-up (3.2 (0 to 12.8) versus 3.5 years (0 to 14); P =.45) were similar between groups. An IOCF occurred in 62 of 11,438 (0.54%) cases. The THAs done via a direct anterior approach experienced the lowest rate of fractures (31 of 7,505, 0.4%) compared to postero-lateral (27 of 3,759, 0.7%; P =.03) and lateral (4 of 165, 2.4%; P <.01) approaches. Of the IOCFs, 48 of 62 (77%) were managed with cerclage cabling, 4 of 62 (6.5%) with intraoperative stem design change and cabling, 4 of 62 (6.5%) with restricted weight-bearing, and 6 of 62 (9.7%) with no modification to the standard postoperative protocol. The IOCF group experienced one case of postoperative component subsidence. No subjects in the IOCF cohort required revision, and rates were similar between groups (0 of 62, 0% versus 215 of 11,376, 1.9%; P =.63). Postoperative Hip dysfunction and Osteoarthritis Outcome Score for Joint Replacement scores were comparable (85.7 versus 86.4; P =.80). Cementless THA complicated by IOCF had similar postoperative revision rates and patient-reported outcome measures at early follow-up when compared to patients not experiencing this complication. Surgeons may use these data to provide postoperative counseling on expectations and outcomes following these rare intraoperative events. [ABSTRACT FROM AUTHOR]- Published

REVERSE total shoulder replacement , *HUMERUS , *HUMERAL fractures , *REOPERATION , *BONE resorption , *TOTAL shoulder replacement - Abstract
Introduction: In the last few years, short metaphyseal-socket prosthetic humeral stems have been introduced for reverse shoulder arthroplasty (RSA). A short stem may have advantages in humeral force distribution, reducing shear stress and preserving bone stock, keeping in mind the need for possible future revision surgery. The main objective of our study was to validate the use of a short stem prosthesis in the surgical treatment of humeral fractures by comparing clinical and radiological outcomes of our studied implant with those obtained with the use of traditional long-stem implants. Methods: In this multicentric, controlled prospective study, 125 patients with proximal three- or four-fragment humerus fractures were selected and treated with RSA. A short stem was used in group A (n = 53, mean age: 75.6 ± 5.6 years old), and a long stem was used in group B (n = 72, mean age: 71.76 ± 3). Active range of motion (ROM), Constant score (CS), Quick DASH, American Shoulder and Elbow Surgeons Shoulder (ASES) score, and Visual Analog Scale (VAS) scores were collected and analyzed at 2 years mean follow-up, as well as humeral and glenoid bone resorption (sum Inoue scores and Sirveaux scores were used). Results: No statistically significant differences were observed between group A and B in ROM, Constant score (51.69 ± 15.8 vs. 53.46 ± 15.96, p > 0.05), Quick DASH (31.5 ± 21.81 vs. 28.79 ± 13.72, p = 0.85), ASES (82.53 ± 17.79 vs. 84.34 ± 15.24, p = 0.57), or the VAS (0.53 ± 1 vs. 0.56 ± 1.07, p = 0.14) at the final follow-up. No statistically significant differences were found in the radiographic parameters between the two groups. No statistically significant differences were found for the average degree of humeral and glenoid bone resorption either. Conclusions: The use of a short metaphyseal-socket stem can be considered a safe, effective, and feasible option in reverse shoulder arthroplasty for treating proximal humerus fractures. Our results are encouraging, with no statistically significant differences identified between the proposed treatment and traditional long stems. [ABSTRACT FROM AUTHOR]

Lumbar discectomy is a commonly performed surgery following which surgical site infection (SSI) may occur. Prior literature has suggested that, following SSI related to lumbar fusion, the rate of subsequent lumbar surgeries is increased over prolonged periods of time. This has not been studied specifically for lumbar discectomy. To define factors associated with SSI following lumbar discectomy and determine if subsequently matched cohorts with and without SSI have differential rates of subsequent lumbar surgery beyond irrigation and debridement (I&Ds) over time. Retrospective cohort study. Adult patients undergoing isolated primary lumbar laminotomy/discectomy were identified from the 2010-2021 M157 PearlDiver database. Exclusion criteria included: age<18 years, preoperative diagnosis of infection, neoplastic, or traumatic diagnoses within 90 days prior to index surgery, additional spinal surgeries on the same day as lumbar discectomy, and not being active in the database for at least 90 days postoperative. From this study population, those who developed SSI were identified based on undergoing I&D within 90 days after surgery. Those with versus without SSI were then matched 1:4 based on age, sex, Elixhauser Comorbidity Index (ECI), and obesity. Following initial I&D, incidence of revision lumbar surgery (revision lumbar discectomy, lumbar laminectomy, lumbar fusion) out to 5 years after lumbar discectomy. Following index isolated lumbar discectomy, those with versus without SSI requiring I&D were matched and compared for incidence of secondary surgery in defined time intervals (0–6 months, 6–12 months, 1–2 years, 2–5 years) using multivariable logistic regression, controlling for patient age, sex, ECI, and obesity status. Of 323,025 isolated lumbar discectomy patients, SSI requiring I&D was identified for 583 (0.18%). Multivariable analysis revealed several independent predictors of these SSIs: younger age (odds ratio [OR] 0.85 per decade increase), ECI (OR 1.22 per 2-point increase), and obesity (OR 1.30). Following matching of those with versus without SSI requiring I&D, rates of subsequent surgery beyond I&D were compared. Those with SSI had significantly increased odds of lumbar revision in the first six months (OR 5.26, p<.001), but not 6–12 months (p=.462), 1–2 years (p=.515), or 2–5 years (p=.677). Overall, SSI requiring I&D is a rare postoperative complication following lumbar discectomy. If occurring, subsequent surgery beyond I&D was higher in the first 6 months, but then not increased at subsequent time points out to five years. [ABSTRACT FROM AUTHOR]

Anterior cervical discectomy and fusion (ACDF) and cervical disc arthroplasty (CDA) are commonly performed operations to address cervical radiculopathy and myelopathy. Trends in utilization and revision surgery rates warrant investigation. To explore the epidemiology, postoperative complications, and reoperation rates of ACDF and CDA. Retrospective cohort study. A total of 433,660 patients who underwent ACDF or CDA between 2011 and 2021 were included in this study. The following data were observed for all cases: patient demographics, complications, and revisions. The PearlDiver database was queried to identify patients who underwent ACDF and CDA between 2011 and 2021. Epidemiological analyses were performed to examine trends in cervical procedure utilization by age group and year. After matching by age, sex, Charlson Comorbidity Index (CCI), levels of operation, and reason for surgery, the early postoperative (2-week), short-term (2-year), and long-term (5-year) complications of both cervical procedures were examined. In total, 404,195 ACDF and 29,465 CDA patients were included. ACDF utilization rose by 25.25% between 2011 and 2014 while CDA utilization rose by 654.24% between 2011-2019 followed by relative plateauing in both procedures. Mann-Kendall trend test confirmed a significant but small rise in ACDF and large rise in CDA procedures from 2011 to 2021 (p<.001). After matching, ACDF and CDA had an overall complication rate of 12.20% and 8.77%, respectively, with the most common complications being subsequent anterior revision (4.96% and 3.35%) and dysphagia (3.70% and 2.98%). The ACDF cohort, especially multilevel ACDF patients, generally had more complications and higher revision rates than the CDA cohort (p<.05). While ACDF utilization has plateaued since 2014, CDA rates have risen by a staggering 654.24% over the past decade. ACDF and CDA complication and revision rates were relatively low in comparison to previously published values, with significantly lower rates in CDA. Although a lack of radiographic data in this study limits its power to recommend either procedure for individual patients with cervical radiculopathy or myelopathy, CDA may be associated with minor improvement in the complication and revision profile.

Introduction: Patients with sleep apnea, affecting up to 1 in 4 older men in the United States, may be at increased risk of postoperative complications after total knee arthroplasty (TKA), including increased thromboembolic and cerebrovascular events, as well as respiratory, cardiac, and digestive complications. However, the extent to which the use of CPAP in patients with sleep apnea has been studied in TKA is limited. Methods: A national, all-payer database was queried to identify all patients who underwent a primary TKA between 2010 and 2021. Patients who had any history of sleep apnea were identified and then stratified based on the use of CPAP. A propensity score match analysis was conducted to limit the influence of confounders. Medical complications, such as cardiac arrest, stroke, pulmonary embolism, transfusion, venous thromboembolism, and wound complications, were collected at 90-days, 1-year, and 2-years. Results: The bivariate analysis showed inferior outcomes for sleep apnea with CPAP use compared to sleep apnea with no CPAP use, in terms of length of stay (5.9 vs. 5.2, p < 0.001), PJI (1.31% vs. 1.14%, p < 0.001), stroke (0.97% vs. 0.82%, p < 0.001), VTE (1.04% vs. 0.82, p < 0.001), and all other complications at 90-days (p < 0.001) except cardiac arrest (0.14% vs. 0.11%, p = 0.052), and aseptic revision (0.40% vs. 0.39%, p = 0.832), PJI (1.81% vs. 1.55%, p < 0.001) and aseptic revision (1.25% vs. 1.06%, p < 0.001) at 1-year, and PJI (2.07 vs. 1.77, p < 0.001) and aseptic revision (1.98 vs. 1.17, p < 0.001) at 2-years. Conclusion: Patients with sleep apnea have increased postoperative complications after undergoing TKA in comparison to patients without sleep apnea. More severe sleep apnea, represented by CPAP usage in this study led to worse postoperative outcomes but further analysis is required signify the role of CPAP in this patient population. Patients with sleep apnea should be treated as a high-risk group. [ABSTRACT FROM AUTHOR]

Introduction: In Western countries, there has been a rise in the prevalence of Crohn's Disease (CD) and primary total knee arthroplasty (TKA). This study delves deeper into the effects of CD on TKA patients by examining (1) the length of in-hospital stay (LOS); (2) the rates of readmission; (3) complications related to implants; and (4) the costs associated with care. Methods: A retrospective analysis using the PearlDiver database was conducted, encompassing the time frame between January 1st, 2005 and March 31st, 2014, focusing on patients who underwent TKA and were either diagnosed with CD or not. Patients with CD were paired with control subjects at a 1:5 ratio based on age, gender, and medical comorbidities. The analysis comprised a total of 96,229 patients (CD = 16,039; non-CD = 80,190). Results: Patients with CD had a notably longer hospital stay (3 v. 2 days, p < 0.0001) and faced significantly higher rates of 90-day readmissions and complications (19.80% v. 14.91%, OR: 1.40, p < 0.0001; 6.88% v. 4.88%, OR: 1.43, p < 0.0001 respectively). Additionally, CD patients incurred greater expenses on the surgery day ($18,365.98 v. $16,192.00) and within 90 days post-surgery ($21,337.46 v. $19,101.42). Conclusion: This study demonstrates longer in-hospital LOS, higher rates of readmissions, implant-related complications, and costs of care among CD patients following primary TKA.

Abstract Background Periprosthetic joint infection (PJI) is a serious complication after total joint arthroplasty (TJA). Although some risk factors of PJI were well studied, the association between trauma and PJI remains unknown in revision patients. Materials and methods Between 2015 and 2018, a total of 71 patients with trauma history before revisions (trauma cohort) were propensity score matched (PSM) at a ratio of 1 to 5 with a control cohort of revision patients without a history of trauma. Then, the cumulative incidence rate of PJI within 3 years after operation between the two groups was compared. The secondary endpoints were aseptic revisions within 3 postoperative years, complications up to 30 postoperative days, and readmission up to 90 days. During a minimal 3-year follow-up, the survival was comparatively analyzed between the trauma cohort and the control cohort. Results The cumulative incidence of PJI was 40.85% in patients with trauma history against 27.04% in the controls (P = 0.02). Correspondingly, the cumulative incidence of aseptic re-revisions was 12.68% in patients with trauma history compared with 5.07% in the control cohort (P = 0.028). Cox regression revealed that trauma history was a risk factor of PJI (HR, 1.533 [95%CI, (1.019,2.306)]; P = 0.04) and aseptic re-revisions (HR, 3.285 [95%CI, (1.790,6.028)]; P

MANUSCRIPTS ,TEXTUAL criticism ,POETRY (Literary form) - Abstract
"Annabel Lee" is Poe's final poem, and although it was intended for publication, it appeared in print only after his death. It was, however, distributed during his lifetime in the form of five manuscripts, all of which survive to this day as cherished relics of the author. The speculative date assigned to each of these manuscripts, and consequently the sequence of revisions, has traditionally been based on when Poe gave them away over the course of the last five or six months of his life. This approach has historically granted the Thompson copy, which Poe had with him in Richmond, the high status of the final and thus the definitive authorized version. Two minor verbal changes have generally been accepted as of little consequence, but many commentators have lamented that the final line of the Thompson version changes "In her tomb by the sounding sea" to "In her tomb by the side of the sea." Looking carefully at the circumstances surrounding the creation and distribution of these manuscripts, as well as the texts themselves, suggests a radically different opinion of the sequence of revisions and a reconsideration of some importance in the matter of textual criticism of these texts for one of Poe's most studied and popular poems.

This study aims to establish a methodological framework for investigating deception in both spoken and written language production. A foundational premise is that the production of deceitful narratives induces a heightened cognitive load that has a discernable influence on linguistic processes during real-time language production. This study includes meticulous analysis of spoken and written data from two participants who told truthful and deceitful narratives. Spoken processes were captured through audio recordings and subsequently transcribed, while written processes were recorded using keystroke logging, resulting in final texts and corresponding linear representations of the writing activity. By grounding our study in a linguistic approach for understanding cognitive load indicators in language production, we demonstrate how linguistic processes, such as text length, pauses, fluency, revisions, repetitions, and reformulations can be used to capture instances of deception in both speaking and writing. Additionally, our findings underscore that markers of cognitive load are likely to be more discernible and more automatically measured in the written modality. This suggests that the collection and examination of writing processes have substantial potential for forensic applications. By highlighting the efficacy of analyzing both spoken and written modalities, this study provides a versatile methodological framework for studying deception during language production, which significantly enriches the existing forensic toolkit.

SPINAL fusion , *PATIENT readmissions , *PROPENSITY score matching , *LUMBAR vertebrae - Abstract
Study Design. Retrospective analysis on prospectively collected data. Objectives. To compare posterior lumbar fusions with versus without an interbody in: (1) Patient-reported outcomes (PROs) at 1 year and (2) postoperative complications, readmission, and reoperations. Summary of Background Data. Elective lumbar fusion is commonly used to treat various lumbar pathologies. Two common approaches for open posterior lumbar fusion include posterolateral fusion (PLF) alone without an interbody and with an interbody through techniques, like transforaminal lumbar interbody fusion. Whether fusion with or without an interbody leads to better outcomes remains an area of active research. Patients and Methods. The Lumbar Module of the Quality Outcomes Database was queried for adults undergoing elective primary posterior lumbar fusion with or without an interbody. Covariates included demographic variables, comorbidities, primary spine diagnosis, operative variables, and baseline PROs, including Oswestry Disability Index, North American Spine Society satisfaction index, numeric rating scale-back/leg pain, and Euroqol 5-dimension. Outcomes included complications, reoperations, readmissions, return to work/activities, and PROs. Propensity score matching and linear regression modeling were used to estimate the average treatment effect on the treated to assess the impact of interbody use on patient outcomes. Results. After propensity matching, there were 1044 patients with interbody and 215 patients undergoing PLF. The average treatment effect on the treated analysis showed that having an interbody or not had no significant impact on any outcome of interest, including 30-day complications and reoperations, 3-month readmissions, 12-month return to work, and 12-month PROs. Conclusion. There were no discernible differences in outcomes between patients undergoing PLF alone versus with an interbody in elective posterior lumbar fusion. These results add to the growing body of evidence that posterior lumbar fusions with and without an interbody seem to have similar outcomes up to 1 year postoperatively when treating degenerative lumbar spine conditions.

- Abstract
Although the sleeve gastrectomy (SG) is the dominant bariatric procedure, studies have shown conversion rates of up to 30%. These conversions are generally for weight regain (WR), insufficient weight loss (IWL) or gastroesophageal reflux disease (GERD). Before 2020, details on why conversions were being performed were not collected in the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) Participant Use Data File (PUF). Now, the indication for sleeve conversion is noted in the PUF, allowing identification and reporting sleeve conversion reasons. We aimed to examine the reasons for SG conversions nationwide. The 2020 MBSAQIP PUF. The 2020 MBSAQIP PUF was examined to determine the reasons why SG were converted to other operations. The data field of "Revision/Conversion Final Indication" was used along with "Procedure type." Primary bariatric operations were excluded. Descriptive statistics were applied. Different reasons for conversion and operations were compared by preoperative characteristics and operative outcomes. There were 103,782 primary SG reported in the 2020 PUF. There were 7181 SG that were converted to other operations. The most common conversion (86.2%) was to Roux-en-Y gastric bypass (RYGB). The main reason for SG conversion was GERD at 48.4%, followed by WR/IWL (41.9%). Biliopancreatic diversion with duodenal switch and single-anastomosis duodenoileal bypass with sleeve patients differed significantly from RYGB patients in specific preoperative characteristics and operative outcomes. The most common procedure SG is converted to is the RYGB. GERD was the most common reason for SG conversion, followed by WR/IWL. • The most common conversion procedure is SG to RYGB. • The main reason for SG conversion is GERD followed by WR/IWL.

BackgroundThere are over 150,000 transgender adolescents in the United States, yet research on outcomes following gender-affirming mastectomy in this age group is limited. We evaluated gender-affirming mastectomy incidence, as well as postoperative complications, including regret, in adolescents within our integrated health care system.MethodsGender-affirming mastectomies performed from January 1, 2013 - July 31, 2020 in adolescents 12-17 years of age at the time of referral were identified. The incidence of gender-affirming mastectomy was calculated by dividing the number of patients undergoing these procedures by the number of adolescents assigned female at birth ages 12-17 within our system at the beginning of each year and amount of follow-up time within that year. Demographic information, clinical characteristics (comorbidities, mental health history, testosterone use), surgical technique, and complications, including mention of regret, of patients who underwent surgery were summarized. Patients with and without complications were compared to evaluate for differences in demographic or clinical characteristics using chi-squared tests.ResultsThe incidence of gender-affirming mastectomy increased 13-fold (3.7 to 47.7 per 100,000 person-years) during the study period. Of the 209 patients who underwent surgery, the median age at referral was 16 years (range 12-17) and the most common technique was double-incision (85%). For patients with greater than 1-year follow-up (n=137, 65.6%), at least one complication was found in 7.3% (n=10), which included hematoma (3.6%), infection (2.9%), hypertrophic scars requiring steroid injection (2.9%), seroma (0.7%), and suture granuloma (0.7%); 10.9 % underwent revision (n=15). There were no statistically significant differences in patient demographics and clinical characteristics between those with and without complications (p>0.05). Two patients (0.95%) had documented postoperative regret but neither underwent reversal surgery at follow-up of 3 and 7 years postoperatively.ConclusionBetween 2013-2020, we observed a marked increase in gender-affirming mastectomies in adolescents. The prevalence of surgical complications was low and of over 200 adolescents who underwent surgery, only two expressed regret, neither of which underwent a reversal operation. Our study provides useful and positive guidance for adolescent patients, their families, and providers regarding favorable outcomes with gender-affirming mastectomy.

Numeric labeling of calories on restaurant menus has been implemented widely, but scientific studies have generally not found substantial effects on calories ordered. The present research tests the impact of a feedback format that is more targeted at how consumers select and revise their meals: real-time aggregation of calorie content to provide dynamic feedback about meal calories via a traffic light label. Because these labels intuitively signal when a meal shifts from healthy to unhealthy (via the change from green to a yellow or red light), they prompt decision makers to course-correct in real time, before they finalize their choice. Results from five preregistered experiments (N = 11,900) show that providing real-time traffic light feedback about the total caloric content of a meal reduces calories in orders, even compared with similar aggregated feedback in numeric format. Patterns of ordering reveal this effect to be driven by people revising high-calorie orders more frequently, leading them to choose fewer and lower-calorie items. Consumers also like traffic light aggregation, indicating greater satisfaction with their order and greater intentions to return to restaurants that use them. The authors discuss how dynamic feedback using intuitive signals could yield benefits in contexts beyond food choice. [ABSTRACT FROM AUTHOR]

- Abstract
Introduction: The rate of marginal ulcer (MU) following primary Roux-en-Y Gastric Bypass (RYGB) is approximately .6- 16%. Few studies have evaluated recurrence rates following surgical revision for MU. The primary aim of this study was to determine the rate of MU recurrence following revision. The secondary aim was to evaluate the impact of truncal vagotomy (TV) on the recurrence rates and analyze potential risk factors associated with the recurrence of MU after revision. Methods: We conducted a retrospective cohort study examining data at a single tertiary academic medical center. Adult patients with a history of RYGB who underwent gastrojejunostomy revision for recurrent MU between the years of 2003-2020 were included. We sought to determine our overall rate of MU following revision, with and without TV. Additionally, we examined the association of risk factors with MU recurrence. Fisher's exact test was used to determine the statistical significance of recurrence rates between the groups. Results: We included 90 patients in the study. The overall recurrence rate for MU was 16.7%. Of the 90 patients, 35 (35.4%) patients underwent TV at the time of revision. The recurrence rate of MU after GJ revision with TV was 14.3% in comparison to those without TV, 18.2% (P = .775). Smoking, steroid, alcohol use, history of cardiac surgery/intervention, and helicobacter pylori were not significantly associated with recurrent MU following revision. Conclusions: The rate of recurrence after revision for MU is high. Adding TV trended towards decreased MU recurrence after revisional surgery, however not significant. Larger studies are needed to evaluate risk factors associated with recurrent MU after revision. [ABSTRACT FROM AUTHOR]

From a positive psychology perspective, this case study explores learners' academic emotions in giving and receiving peer feedback on second language writing and the possible influences of emotions on learners' uptake of peer feedback. The data were collected from five undergraduates at a Chinese university, including semi-structured interviews, stimulated recalls, peer feedback, students' essays and observation notes. Using content analysis, the study revealed 24 academic emotions, including positive, neutral and negative emotions. Positive emotions were found to improve the number and quality of revisions, whereas negative emotions could not necessarily impede learners' revision operations. The findings suggest the dynamic interplay among learners' positive emotions, positive characteristics and harmonious writing community. [ABSTRACT FROM AUTHOR]

Summary: Output gap revisions can be large even after many years. Real‐time reliability tests might therefore be sensitive to the choice of the final output gap vintage that the real‐time estimates are compared to. This is the case for the Federal Reserve's output gap. When accounting for revisions in response to the global financial crisis in the final output gap, the improvement in real‐time reliability since the mid‐1990s is much smaller than found by Edge and Rudd (Review of Economics and Statistics, 2016, 98(4), 785–791). The negative bias of real‐time estimates from the 1980s has disappeared, but the size of revisions continues to be as large as the output gap itself. We systematically analyse how the real‐time reliability assessment is affected through varying the final output gap vintage. We find that the largest changes are caused by output gap revisions after recessions. Economists revise their models in response to such events, leading to economically important revisions for not only the most recent years but also reaching back up to two decades. This might improve the understanding of past business cycle dynamics but decreases the reliability of real‐time output gaps ex post. [ABSTRACT FROM AUTHOR]

This study determined the degree to which students used peer feedback from Facebook to revise their writing papers and explored the students' perspectives on a framework of using a social network for peer commentaries. The study enrolled two intact groups, 40 students in the control group and 32 students in the experimental group, at a university in Ho Chi Minh City, Vietnam. The student's initial and final drafts, peer reviews, and semi-structured interviews were used to collect data. The results indicated that 45% of changes were made in response to peer reviews, while 55% were made solely on the basis of the student's own judgments. Additionally, the overall number of revisions made by students was greater than the number of revisions caused by comments at higher levels such as "Clause,""Sentence," and "Paragraph." Numerous previous studies refuted the current study's results, raising questions for researchers/instructors considering using Facebook as a forum for their writing classes because the students become more responsible for developing their writing skills.

In this paper, the authors discuss their experiences with ungrading at a small public university in the U.S. and a large public university in Germany. The courses described are Calculus 1 and a content course for pre-service secondary teachers of mathematics. The professors teach differently: one with lecture, the other with inquiry-based learning, and choose to use elements of ungrading in different ways. In one case, the professor lets students self-evaluate their homework, while in the other the professor uses a mix of specifications grading and ungrading for the final grade. We outline and compare our assessment approaches and discuss student performance and feedback. We also present some patterns relating to gender: in both cases, we observed that women students chose lower self-evaluations than men students. We end this paper with a general reflection on our teaching experience and our plans to use ungrading in the future. [ABSTRACT FROM AUTHOR]

- Abstract
Parkinson disease (PD) is an established risk factor for higher rates of complications and revision surgery following shoulder arthroplasty, yet the economic burden of PD remains to be elucidated. The purpose of this study is to compare rates of complication and revisions as well as inpatient charges for shoulder arthroplasty procedures between PD and non-PD patients using an all-payer statewide database. Patients undergoing primary shoulder arthroplasty from 2010 to 2020 were identified from the New York (NY) Statewide Planning and Research Cooperative System (SPARCS) database. Study groups were assigned based on concomitant diagnosis of PD at the time of index procedure. Baseline demographics, inpatient data, and medical comorbidities were collected. Primary outcomes measured were accommodation, ancillary, and total inpatient charges. Secondary outcomes included postoperative complication and reoperation rates. Logistic regression was performed to evaluate effect of PD on shoulder arthroplasty revision and complication rates. All statistical analysis was performed using R. A total of 39,011 patients (429 PD vs. 38,582 non-PD) underwent 43,432 primary shoulder arthroplasties (477 PD vs. 42,955 non-PD) with mean follow-up duration of 2.9 ± 2.8 years. The PD cohort was older (72.3 ± 8.0 vs. 68.6 ± 10.4 years, P <.001), with greater male composition (50.8% vs. 43.0%, P =.001), and higher mean Elixhauser scores (1.0 ± 4.6 vs. 7.2 ± 4.3, P <.001). The PD cohort had significantly greater accommodation charges ($10,967 vs. $7,661, P <.001) and total inpatient charges ($62,000 vs. $56,000, P <.001). PD patients had significantly higher rates of revision surgery (7.7% vs. 4.2%, P =.002) and complications (14.1% vs. 10.5%, P =.040), as well as significantly higher incidences of readmission at 3 and 12 months postoperatively. After controlling for age and baseline comorbidities, PD patients had 1.64 times greater odds of reoperation compared to non-PD patients (95% CI 1.10, 2.37; P =.012) and a hazard ratio of 1.54 for reoperation when evaluating revision-free survival following primary shoulder arthroplasty (95% CI 1.07, 2.20; P =.019). PD confers a longer length of stay, higher rates of postoperative complications and revisions, and greater inpatient charges in patients undergoing TSA. Knowledge of the associated risks and resource requirements of this population will aid surgeons in their decision making as they continue to provide care to a growing number of patients affected by PD.

In recent decades many changes have been adopted in the fungal nomenclature, including the names of yeasts, to achieve a more natural and uniform systematics. The use of one correct name is essential for communication, the search for new knowledge, research studies or business purposes not only in the brewing branch. Nevertheless, how can such rapid progress be followed? The paper attempted to briefly explain the reasons for immense changes that have occurred in the taxonomic and nomenclatural system mainly as a result of modern molecular findings. The process of reclassification is demonstrated on a group of selected contaminants currently detected in Czech beers or breweries. This article presents several online databases that document the ongoing changes and make it easy for experts from various fields to find valid names.

Study Design. A retrospective cohort study using the 2010--2020 MSpine PearlDiver administrative data set. Objective. To compare perioperative adverse events and fiveyear revisions for single-level anterior cervical discectomy and fusion (ACDF) versus posterior cervical foraminotomy (PCF). Summary of Background Data. Cervical disk disease can often be treated surgically using single-level ACDF or PCF. Prior studies have suggested that posterior approaches provide similar shortterm outcomes as ACDF; however, posterior procedures may have an increased risk of revision surgery. Materials and Methods. The database was queried for patients undergoing elective single-level ACDF or PCF (excluding cases performed for myelopathy, trauma, neoplasm, and/or infection). Outcomes, including specific complications, readmission, and reoperations, were assessed. Multivariable logistic regression was used to ascertain odds ratios (OR) of 90-day adverse events controlling for age, sex, and comorbidities. Kaplan-Meier survival analysis was performed to determine five-year rates of cervical reoperation in the ACDF and PCF cohorts. Results. A total of 31,953 patients treated by ACDF (29,958, 93.76%) or PCF (1995, 6.24%) were identified. Multivariable analysis, controlling for age, sex, and comorbidities, demonstrated that PCF was associated with significantly greater odds of aggregated serious adverse events (OR 2.17, P< 0.001), wound dehiscence (OR 5.89, P< 0.001), surgical site infection (OR 3.66, P<0.001), and pulmonary embolism (OR 1.72, P=0.04). However, PCF was associated with significantly lower odds of readmission (OR 0.32, P<0.001), dysphagia (OR 0.44, P< 0.001), and pneumonia (OR 0.50, P= 0.004). At five years, PCF cases had a significantly higher cumulative revision rate compared with ACDF cases (19.0% vs. 14.8%, P< 0.001). Conclusions. The current study is the largest to date to compare short-term adverse events and five-year revision rates between single-level ACDF and PCF for nonmyelopathy elective cases. Perioperative adverse events differed by procedure, and it was notable that the incidence of cumulative revisions was higher for PCF. These findings can be used in decision-making when there is clinical equipoise between ACDF and PCF. [ABSTRACT FROM AUTHOR]

The article focuses on the importance of mobile applications in enterprises with a focus on logistics in the service sector. In the theoretical part, individual software applications in the field of occupational health and safety, fire protection, which are used in Slovakia and the Czech Republic are clearly described. The article contains a brief overview of the legislative regulations on the basis of which the obligations for management decisions in enterprises arise. A telephone survey was conducted in 110 micro, small and medium-sized enterprises between 2022 and 2023 in order to determine the use of software solutions in ensuring the fulfilment of obligations in the field of occupational safety and health and fire protection. To collect data, research questions were set and a questionnaire was developed, which included 6 merit questions, identification questions and a specific question aimed at finding out the prioritisation of the most preferred mobile application features in the study area. The questions were closed-ended, with options where the respondent could choose only one answer. SPSS for Windows version 21.0 was used for statistical analysis and processing of the collected data. We used methods of statistical description, analysed using relative abundance, arithmetic mean, standard deviation and median. At the level of statistical inference, we used chi-square goodness-of-fit tests to analyse categorical variables. We also used nonparametric tests, Friedman analysis of variance, 3D pie charts, and 3D group bar charts. We found that business representatives had a significantly higher preference for the functionality "record of initial and recurrent BOZP and PO training", followed by the second most preferred functionality "OSH inspections and fire prevention inspections". The research focused on logistics enterprises. [ABSTRACT FROM AUTHOR]

Study Design: Prospective cohort study. Objectives: In spine surgery, accurate screw guidance is critical to achieving satisfactory fixation. Augmented reality (AR) is a novel technology to assist in screw placement and has shown promising results in early studies. This study aims to provide our early experience evaluating safety and efficacy with an Food and Drug Administration-approved head-mounted (head-mounted device augmented reality (HMD-AR)) device. Methods: Consecutive adult patients undergoing AR-assisted thoracolumbar fusion between October 2020 and August 2021 with 2 -week follow-up were included. Preoperative, intraoperative, and postoperative data were collected to include demographics, complications, revision surgeries, and AR performance. Intraoperative 3D imaging was used to assess screw accuracy using the Gertzbein-Robbins (G-R) grading scale. Results: Thirty-two patients (40.6% male) were included with a total of 222 screws executed using HMD-AR. Intraoperatively, 4 (1.8%) were deemed misplaced and revised using AR or freehand. The remaining 218 (98.2%) screws were placed accurately. There were no intraoperative adverse events or complications, and AR was not abandoned in any case. Of the 208 AR-placed screws with 3D imaging confirmation, 97.1% were considered clinically accurate (91.8% Grade A, 5.3% Grade B). There were no early postoperative surgical complications or revision surgeries during the 2 -week follow-up. Conclusions: This early experience study reports an overall G-R accuracy of 97.1% across 218 AR-guided screws with no intra or early postoperative complications. This shows that HMD-AR-assisted spine surgery is a safe and accurate tool for pedicle, cortical, and pelvic fixation. Larger studies are needed to continue to support this compelling evolution in spine surgery. [ABSTRACT FROM AUTHOR]

Purpose: Total elbow arthroplasty (TEA) is rarely performed compared to other arthroplasties. For many surgical procedures, literature shows better outcomes when they are performed by experienced surgeons and in so-called ‘high-volume’ hospitals. We systematically reviewed the literature on the relationship between surgical volume and outcomes following TEA. Methods: A literature search was performed using the MEDLINE, EMBASE and CINAHL databases. The literature was systematically reviewed for original studies comparing TEA outcomes among hospitals or surgeons with different annual or career volumes. For each study, data were collected on study design, indications for TEA, number of included patients, implant types, cut-off values for volume, number and types of complications, revision rate and functional outcome measures. The methodological quality of the included studies was assessed using the Newcastle–Ottawa Scale. Results: Two studies, which included a combined 2301 TEAs, found that higher surgeon volumes were associated with lower revision rates. The examined complication rates did not differ between high- and low-volume surgeons. In one study, low-hospital volume is associated with an increased risk of revision compared to high-volume hospitals, but for other complication types, no difference was found. Conclusions: Based on the results, the evidence suggests that high-volume centers have a lower revision rate in the long term. No minimum amount of procedures per year can be advised, as the included studies have different cut-off values between groups. As higher surgeon- and center-volume, (therefore presumably experience) appear to yield better outcomes, centralization of total elbow arthroplasty should be encouraged.

The use of intraoperative CT has continued to grow in recent years, as various techniques leverage the promise of improved instrumentation accuracy and the hope for decreased complications. Nonetheless, the literature regarding the short- and long-term complications associated with such techniques remains scant and/or confounded by indication and selection bias. To use causal inference techniques to determine whether intraoperative CT use is associated with an improved complication profile as compared to conventional radiography for single-level lumbar fusions, an increasingly commonplace application for this technology. Inverse probability weighted retrospective cohort study carried out within a large integrated health care network. Adult patients who underwent surgical treatment of spondylolisthesis via lumbar fusion from January 2016 to December 2021. Our primary outcome was the incidence rate of revision surgery. Our secondary outcome was the incidence of composite 90-day complications (deep and superficial surgical site infection, venous thromboembolic events, and unplanned readmissions). Demographics, intraoperative information, and postoperative complications were abstracted from electronic health records. A propensity score was developed utilizing a parsimonious model to account for covariate interaction with our primary predictor, intraoperative imaging technique. This propensity score was utilized in the creation of inverse probability weights to adjust for indication and selection bias. The rate of revisions within 3 years as well as the rate of revisions at any time-point were compared between cohorts using Cox regression analysis. The incidence of composite 90-day complications were compared using negative binomial regression. Our patient population consisted of 583 patients, with 132 who underwent intraoperative CT and 451 who underwent conventional radiographic techniques. There were no significant differences between cohorts following inverse probability weighting. No significant differences were detected in 3-year revision rates (HR, 0.74 [95% CI 0.29, 1.92]; p=.5), overall revision rates (HR, 0.54 [95% CI 0.20, 1.46]; p=.2), or 90-day complications (RC -0.24 [95% CI –1.35, 0.87]; p=.7). Intraoperative CT use was not associated with an improved complication profile in either the short- or long-term for patients undergoing single-level instrumented fusion. This observed clinical equipoise should be weighed against resource and radiation-related costs when considering intraoperative CT for low complexity fusions. [ABSTRACT FROM AUTHOR]

- Abstract
Computer navigation is an increasingly utilized technology that is considered with total hip arthroplasty (THA). However, the evidence to support this practice is mixed. The current study leveraged a large national administrative database to compare 90-day adverse events as well as 5-year all-cause revision and dislocation rates following THA performed with and without imageless navigation. From 2010 to 2020, a large national database was queried for THA cases performed for osteoarthritis. Cases with or without imageless navigation were matched at 1:4 based on age, sex, and Elixhauser Comorbidity Index (ECI) score. Ninety-day adverse events were assessed and compared with multivariate analyses. Five-year incidence of revision and dislocation were also assessed between cohorts. Use of THA imageless navigation increased from 2010 (2.5% of cases) to 2020 (5.5% of cases; P <.001). After matching, 11,990 THA patients with navigation and 47,948 without navigation were identified. Overall, 90-day adverse events were observed in 7.0% of the population. Multivariate analysis controlling for age, sex, and ECI demonstrated a difference in only one 90-day adverse event; wound dehiscence, which had higher odds in the navigation group (odds ratio, 1.60, P <.001). At 5 years, revisions for the navigated group were higher (4.4 versus 3.6%: P =.006), while dislocations were not significantly different. THA imageless navigation was not found to be associated with improved 90-day postoperative adverse events or differences in the 5-year rates of revision or dislocation. The current data were unable to identify clear advantages of this evolving technology for primary THA. [ABSTRACT FROM AUTHOR]

This study aims to establish a methodological framework for investigating deception in both spoken and written language production. A foundational premise is that the production of deceitful narratives induces a heightened cognitive load that has a discernable influence on linguistic processes during real-time language production. This study includes meticulous analysis of spoken and written data from two participants who told truthful and deceitful narratives. Spoken processes were captured through audio recordings and subsequently transcribed, while written processes were recorded using keystroke logging, resulting in final texts and corresponding linear representations of the writing activity. By grounding our study in a linguistic approach for understanding cognitive load indicators in language production, we demonstrate how linguistic processes, such as text length, pauses, fluency, revisions, repetitions, and reformulations can be used to capture instances of deception in both speaking and writing. Additionally, our findings underscore that markers of cognitive load are likely to be more discernible and more automatically measured in the written modality. This suggests that the collection and examination of writing processes have substantial potential for forensic applications. By highlighting the efficacy of analyzing both spoken and written modalities, this study provides a versatile methodological framework for studying deception during language production, which significantly enriches the existing forensic toolkit.

Background: Worldwide, the majority of total hip arthroplasties (THAs) placed in patients <55 years are uncemented. However, little is known about the preferred method of fixation in revision hip arthroplasty in young patients. The aim of this study was to assess potential differences in the method of fixation used between primary and revision THA in young patients using data from the Dutch Arthroplasty Register. Methods: All primary THA placed in patients younger than 55 years, registered in the LROI between 2007 and 2019 were included n = 28,516). Kaplan-Meier survival analyses were used to estimate the survival of primary THA by method of fixation. Additionally, survival of revision procedures that changed or did not change in method of fixation were estimated. McNemar's test was used to assess differences in the proportion of cemented and uncemented fixation between primary and revision THA. Results: In all acetabular revisions, the use of cemented fixation increased statistically significant with 39% (95% CI, 34–45, p < 0.001) from 23% in primary THA to 62% in revision procedures. In all femoral revisions, the increase of cemented fixation was also statistically significant with 25% (95% CI, 19–31, p < 0.001), from 11% in primary THA to 36% in revision surgery. For both revised acetabular and femoral components, we found no statistically significant difference in the 5-year survival between revision procedures that changed or did not change in method of fixation. Conclusions: There was a significant change towards cemented fixation between primary and revision THA in young patients in the Netherlands, which was especially pronounced in acetabular revisions. No significant difference in short-term survival was found between revision procedures that changed or did not change in method of fixation. Long-term follow-up data are needed to evaluate the effect of this change in fixation method on the outcome of revision procedures in young patients. [ABSTRACT FROM AUTHOR]

Both anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA) are the standard of care for various end-stage degenerative conditions of the glenohumeral joint. The purpose of this prospective study was to compare clinical outcomes of aTSA and rTSA using the same platform total shoulder arthroplasty system at a minimum follow-up of 8 years. An international multicenter data registry was used to identify patients undergoing primary aTSA or rTSA with a minimum of 8-year follow-up. Patients were scored preoperatively and at latest follow-up using 6 outcome and 4 range of motion metrics. Patients graded global shoulder function on a 0-10 scale. Patient satisfaction was classified as much better, better, unchanged, or worse. Pain was graded using the Visual Analog Scale. A student's 2-tailed paired t -test, Chi-squared test, or Wilcoxon rank-sum test were used when appropriate, where P <.05 indicates significant differences. A total of 364 aTSA patients and 278 rTSA patients were included. rTSA had greater mean age (aTSA 65.1, rTSA 71.2, P <.0001) and shorter mean follow-up (aTSA 115.2 months, rTSA 109.7 months; P =.0002). Postoperatively, all patients demonstrated significant improvements in pain and function. Preoperatively, aTSA patients had greater active abduction and forward elevation, global function, Constant Score, and the University of California, Los Angeles score. At latest follow-up, aTSA had greater active abduction, forward elevation, external rotation, and Simple Shoulder Test scores. There were no postoperative differences in patient satisfaction, shoulder function, pain, or any other outcome measure between the groups. aTSA patients had a greater revision rate (aTSA 5.8%, rTSA 1.8%; P =.0114), with no difference in complication rates. Humeral radiolucent lines were present in 20.9% of aTSA patients and 37.1% of rTSA patients (P =.0011). Glenoid radiolucent lines were present in 48.0% of aTSA patients (average score of 1.5). Scapular notching was present in 14.5% of rTSA patients (average grade of 0.26). This study is one of the largest to date that compares aTSA and rTSA with a minimum follow-up of 8 years. Significant improvements are seen in both aTSA and rTSA. For both groups, the complication rate was lower than previously reported in the literature. At the latest follow-up, pain relief and global function were significantly improved with high patient satisfaction in both groups, with no statistical differences found. This study provides physicians with information to help guide them when advising patients as to what they can expect at a minimum of 8 years after aTSA and rTSA. [ABSTRACT FROM AUTHOR]

In recent decades many changes have been adopted in the fungal nomenclature, including the names of yeasts, to achieve a more natural and uniform systematics. The use of one correct name is essential for communication, the search for new knowledge, research studies or business purposes not only in the brewing branch. Nevertheless, how can such rapid progress be followed? The paper attempted to briefly explain the reasons for immense changes that have occurred in the taxonomic and nomenclatural system mainly as a result of modern molecular findings. The process of reclassification is demonstrated on a group of selected contaminants currently detected in Czech beers or breweries. This article presents several online databases that document the ongoing changes and make it easy for experts from various fields to find valid names. [ABSTRACT FROM AUTHOR]

In this article, we critically review the changes made to the DSM-5 Text Revision published in 2022 regarding the diagnostic entity of Attention Deficit/Hyperactivity Disorder (ADHD). We structure our critique around three points. The first discusses the acknowledgment of ADHD as a neurodevelopmental disorder. The second examines the definition of ADHD provided in the updated edition of the manual. The third scrutinizes the changes in the diagnostic criteria for ADHD and assesses whether these changes make the diagnosis more accurate. We conclude that DSM's latest edition does not escape the logical and scientific pitfalls of its predecessor. DSM-5-TR keeps the faith in the neo-Kraepelinian paradigm by explicitly and implicitly cultivating the essentialist medical scientific metaphor of disorder, creating the illusion that it represents scientific progress that validates ADHD as a neurodevelopmental disorder.

The paper is devoted to the problem of identifying the text placed by Origen in the sixth column of the Hexapla, Theodotion’s revision. This text, along with the revisions of Aquila and Symmachus, was actively used by the Church Fathers in the exegesis of Old Testament texts (by Chrysostom, Theodorite, Jerome, etc.). In the middle of the 20th century, the prevailing opinion, which was probably going back to the blessed Jerome, attributed the authorship of this text to a certain Theodotion who lived in the 2nd century AD. Moreover, according to this opinion the translation of the book of Daniel in the Septuagint is also attributed to Theodotion. Since the second half of the 20th century, there has been a surge of research on the origin of the sixth column and its connection with Theodotion. Various studies have emerged that put forward a variety of new hypotheses. This was especially promoted by the discovery of the Greek Minor Prophets Scroll in 1952. The Russian-language literature has not covered this issue sufficiently. More or less competently, this problem was touched upon in an article in the Orthodox Encyclopedia. The present paper aims to view the problem of identifying the text of the sixth column of the Hexapla considering the following aspects: 1. The authorship and origin of Theodotion’s revision. 2. The question whether Theodotion (2nd century AD) mentioned by the Church Fathers had any relationship to the Greek translation of the Book of Daniel ascribed to him. 3. The questions whether the material collected by Origen in the sixth column is homogeneous and how it is connected with the historical Theodotion. 4. Characteristic features of Theodotion’s revision. Thus, the paper attempts to offer a complete picture of the revision of Theodotion through the resolution of the questions raised.

Researchers and practitioners in foreign language learning continue investigating evolving technologies like machine translators and other artificial intelligence-assisted programs in classrooms. However, less attention has been given to less commonly taught languages, which often lack relevant resources compared to widely taught foreign languages such as English, despite machine translators’ potential in facilitating foreign language writing. This exploratory case study aims to address this gap by examining how US university students learning a less commonly taught language, Korean, use machine translators to revise their writing. Students were trained in a modified version of the Guided Use of Machine Translation model, which requires active engagement from students in selecting, comparing, revising, and justifying their writing choices. By analyzing their cognitive and behavioral engagement, the study sheds light on students’ approaches to incorporating machine translators’ output as feedback into their writing process. The findings suggest that students primarily focus on differences in word choice between their original writing and machine translators’ output over other areas such as particle usage. Students generally demonstrated the ability to accurately identify and correct their errors. Various revision strategies were implemented but adopting exact machine translators’ output was more commonly used, while students also exercised autonomy in their language choices.

The ability to perform revisions targeting the content of the text is important for text quality improvement, and it is hypothesized that lower-level transcription processes need to be automatized in order to free up capacity for higher-level processes such as revision. However, for people with reading and writing difficulties due to underlying difficulties with decoding and spelling, the transcription process is rarely automatized because of their troubles with spelling. One possible way to circumvent spelling difficulties, and possibly gaining capacity for higher level processes such as revision, is to write using speech-to-text (STT). This study investigates the revisions performed when children with reading and writing difficulties (n = 16), and a reference group without such difficulties (n = 12), compose text using STT and using a keyboard. More specifically, the study investigates whether, and if so how, revisions at various levels, errors left in the final text product, and text quality differ between conditions and between groups. The compositions were logged using keystroke logging (keyboard) and audio- and screen-recording (STT). The level of revisions were manually coded. The results showed that children with reading and writing difficulties gain more from composing with STT compared to keyboard than the reference group. They leave fewer errors in their final text product when composing by means of STT, even though they need to engage more in the correction of surface errors because of the large number of STT errors. Despite the numerous STT errors, neither the proportion of meaning-related revisions nor text quality decreased in composing with STT (for either of the groups). Taken together, the results suggest, albeit not emphatically, that STT may be appropriate as a facilitatory tool for children with reading and writing difficulties. However, more research is needed to investigate instruction that addresses strategies for STT transcription and highlights the shortcomings of the tool in the target language, and also focuses specifically on higher-level aspects of composition such as planning or revising, in order to gain further knowledge about the feasibility of using STT as a means of composition for children who struggle with writing, and its possible effects over time.

Study Design: A retrospective cohort study.Objective: To determine if (1) preoperative marijuana use increased complications, readmission, or reoperation rates following anterior cervical discectomy and fusion (ACDF), (2) identify if preoperative marijuana use resulted in worse patient-reported outcome measures (PROMs), and (3) investigate if preoperative marijuana use affects the quantity of opioid prescriptions in the perioperative period.Summary Of Background Data: A growing number of states have legalized recreational and/or medical marijuana, thus increasing the number of patients who report preoperative marijuana use. The effects of marijuana on clinical outcomes and PROMs in the postoperative period are unknown.Methods: All patients 18 years of age and older who underwent primary one- to four-level ACDF with preoperative marijuana use at our academic institution were retrospectively identified. A 3:1 propensity match was conducted to compare patients who used marijuana versus those who did not. Patient demographics, surgical characteristics, clinical outcomes, and PROMs were compared between groups. Multivariate regression models measured the effect of marijuana use on the likelihood of requiring a reoperation and whether marijuana use predicted inferior PROM improvements at the one-year postoperative period.Results: Of the 240 patients included, 60 (25.0%) used marijuana preoperatively. Multivariate logistic regression analysis identified marijuana use (odds ratio=5.62, P <0.001) as a predictor of a cervical spine reoperation after ACDF. Patients who used marijuana preoperatively had worse one-year postoperative Physical Component Scores of the Short-Form 12 (PCS-12) ( P =0.001), Neck Disability Index ( P =0.003), Visual Analogue Scale (VAS) Arm ( P =0.044) and VAS Neck ( P =0.012). Multivariate linear regression found preoperative marijuana use did not independently predict improvement in PCS-12 (β=-4.62, P =0.096), Neck Disability Index (β=9.51, P =0.062), Mental Component Scores of the Short-Form 12 (MCS-12) (β=-1.16, P =0.694), VAS Arm (β=0.06, P =0.944), or VAS Neck (β=-0.44, P =0.617).Conclusion: Preoperative marijuana use increased the risk of a cervical spine reoperation after ACDF, but it did not significantly change the amount of postoperative opioids used or the magnitude of improvement in PROMs.Level Of Evidence: Levwl III.

While accounting research has extensively examined initial guidance disclosures, the disclosures that managers make when initial forecasts become materially inaccurate have received much less attention. These updates are unique because managers are communicating that their initial forecasts are no longer correct. In this context, we examine how earnings forecast withdrawals affect managers' reporting reputation, relative to earnings revisions and nondisclosure. While managers face immediate negative market consequences after withdrawals, they enjoy reputational benefits (in the form of improved credibility) in the long run when guidance updates resume. In contrast, reporting reputation does not improve for managers who revise forecasts or for those who choose not to update at all. Difference-in-differences analyses confirm this incremental boost to credibility that is associated with withdrawals. This evidence suggests disclosing what managers do not know may be as important as disclosing what they do know when building a reporting reputation. [ABSTRACT FROM AUTHOR]

- Abstract
Study Design: Retrospective additional analysis of a prospective follow-up study.Objectives: We aimed to find out whether poor postoperative sagittal alignment increases revisions for adjacent segment disease (ASD) after lumbar spine fusion (LSF) performed for degenerative lumbar spine disease.Summary Of Background Data: Revisions for ASD accumulate over time after LSF for degenerative lumbar spine disease. The etiology of ASD is considered multifactorial. Yet, the role of postoperative sagittal balance in this process remains controversial.Materials and Methods: A total of 215 consecutive patients who had undergone an elective LSF surgery for spinal stenosis with (80%) or without (20%) spondylolisthesis were analyzed. Spinal reoperations were collected from the hospital records. Preoperative and postoperative sagittal alignment were evaluated from standing radiographs. The risk of revisions for ASD was evaluated by Cox proportional hazards regression models.Results: We did not find the poor postoperative balance [pelvic incidence-lumbar lordosis (LL) >9°] to significantly increase the risk of revisions for ASD: crude hazard ratio (HR)=1.5 [95% confidence interval (CI): 0.8-2.7], adjusted (by age, sex, pelvic incidence, fusion length, and the level of the caudal end of fusion): HR=1.7 (95% CI: 0.9-3.3). We found higher LL outside the fusion segment (LL-segmental lordosis) to decrease the risk of revisions for ASD: HR=0.9 (95% CI: 0.9-1.0).Conclusion: Poor sagittal balance has only a limited role as a risk factor for the revisions for ASD among patients with degenerative spinal disease. However, the risk for ASD might be the greatest among patients with reduced spinal mobility. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Background Context: As surgical indications for cervical disc arthroplasty (CDA) continue to expand, a growing patient population is now becoming indicated for this procedure. Little is known about whether CDA is safe in the overweight and obese populations, and how this procedure compares to anterior cervical discectomy and fusion (ACDF) in this particular demographic., Purpose: To evaluate the outcomes of CDA across varying levels of body mass indices and to compare these to ACDF., Design: Retrospective cohort study., Patient Sample: A total of 12,454 patients who underwent CDA and 45,513 patients who underwent ACDF between 2011 and 2020 were included in this study., Outcome Measures: The following data were observed for all cases: patient demographics, complications, revisions., Methods: The PearlDiver database was queried to identify all adults who underwent single-level CDA. Patients were stratified by body mass index (BMI), defined as Healthy Weight (<25kg/m2), Overweight (25-30kg/m2), Obese (30-40kg/m2), and Morbidly Obese (>40kg/m2). Patient demographics and comorbidities were compared before matching, and medical and surgical complications were compared after matching for age, sex, and Charlson Comorbidity Index (CCI). Similar comparative analyses were performed on all obese patients (>30kgm/2) who underwent single-level CDA and single-level ACDF., Results: In total, 1907 Healthy Weight, 3295 Overweight, 5431 Obese, and 1821 Morbidly Obese patients were included. The mean age was between 45.43-47.41 years, 57.12-71.68% were female, and mean CCI was 1.16-1.73 across groups (all p<0.001). Mean CCI (Healthy Weight=1.16, Overweight=1.31, Obese=1.47, Morbidly Obese=1.63) and rate of comorbidities, such as diabetes (19.19%, 25.74%, 37.51%, 48.65%), hypertension (45.20%, 56.18%, 69.21%, 76.22%), and hyperlipidemia (49.34%, 60.61%, 65.33%, 64.96%), generally increased with increasing BMI (p<0.001). After matching, mean age was 44.59 years, 70.98% were female, and mean CCI was 1.07 for all groups. At 90 days postoperatively, medical complications, including infection, wound dehiscence, and readmissions, were comparable (p>0.05). At 2 years postoperatively, anterior revision was higher in Healthy Weight patients (30.27%, 28.11%, 24.71%, 24.96%, p=0.005) but other surgical complications, including dysphagia, dysphonia, and implant failure, were otherwise comparable (p>0.05). Comparison of all obese patients across cervical procedures revealed higher rates of 90-day emergency department visits (ACDF=21.56% vs 16.65%, p<0.001) and 1-year hardware removal (1.49% vs 0.81%, p=0.002), wound exploration (0.73% vs 0.35%, p=0.018), and posterior fusion (1.14% vs 0.44%, p<0.001) and lower rates of anterior revision (18.82% vs 23.68%, p<0.001) in ACDF patients compared to CDA patients., Conclusion: CDA may be safe across varying levels of obesity without any appreciable change in medical and surgical complications. In addition, single-level ACDF may result in higher complications than single-level CDA in the obese population., (Copyright © 2024. Published by Elsevier Inc.)

This study examines the implementation of Criterion, an automated writing evaluation system developed by ETS, as a source of diagnostic feedback on learners' linguistic performance in a Vietnamese EFL writing classroom. Thirty-eight second-year English majors had access to Criterion for a five-month period. Data include Criterion error tags on students' essays from multiple practice sessions, recorded think-aloud protocols as students engaged with the feedback for revisions, and first and revised drafts students submitted to Criterion. The main findings indicate Criterion's satisfactory precision and capacity to trigger various engagement strategies among learners, but reservations remain due to students' modest response accuracy and lack of substantive revisions to their texts. Important implications for formative feedback practices in EFL writing classrooms and the adaptation of Criterion's technical capacities are accordingly presented. [ABSTRACT FROM AUTHOR]

There are global university rankings of higher educational institutions. Public and private universities around the world endeavour to improve their rankings and to be at the top of the ranking lists. These rankings help students in finding out prominent universities for getting admitted, and after graduation in a better job placement. There are significant key performance indicators (KPIs) to determine these rankings. These KPIs are based on data, knowledge and information of a university (higher education institution [HEI]). Effective decision making through these KPIs improve the ranking and performance of the university. Business intelligence (BI) software for educational institutions is dedicated towards the provision of solutions for decision making. Therefore, the BI software might improve academic performance. However, literature reveals that the failure rate of BI projects is between 70% to 80%. In addition, they are costly solutions and require a huge amount of time for implementation. Hence, there is a need to find alternate solutions for better decision making that is economical and time efficient. An improvement in performance means improvement in the ranking of the university that is centred on better decision making, focusing on the significant KPIs, such as KPIs used by the Times Higher Education for world's university rankings and QS university rankings. This paper offers a framework of decision making through a visual digital dashboard for the vice chancellors (heads or presidents) of higher education institutions, based on a formal working structure of a university. Moreover, this framework focuses on policies and procedures linked to specific KPIs of the university and the impacts of these policies or procedures on these KPIs. Visual digital dashboard provides the statistics through comparison reports, flowcharts, graphs and trends. Effective decisions could be taken to improve the performance of an underperforming KPI; if there is a need of improvement for the KPI, a revision(s) is recommended in the policy or linked procedure(s) of that KPI, and the impact of revision(s) is measured again through the visual digital dashboard of decision making. These revisions of policies or procedures linked to any KPI is a continuous process until an expected outcome is achieved. According to the framework, some departments of the university play a vital role in the implementation and revisions of these policies or procedures. This framework is termed as VCDBDM (Vice Chancellor's Dashboard of Decision Making) framework that offers a visual digital dashboard as a decision support system to the vice chancellors (VCs)/heads/presidents of the universities. Altogether, the offered framework of VCDBDM provides an opening to the universities of Oman, GCC countries, MENA region, and worldwide universities concerning its application for successful decision making and improvements in the performances and rankings of the universities.

With the development of open science and technological innovation, using sharing data and molecular biology techniques in the study of taxonomy and systematics have become a crucial component of plants, which undoubtedly helps us discover more hidden outliers or deal with difficult taxa. In this paper, we take Dennstaedtia smithii as an example, based on sharing molecular database, virtual herbarium and plant photo bank, to clarify the outliers that have been hidden in Dennstaedtia and find the key morphological traits with consistent of molecular systematics. In molecular phylogenetic analyses, we used rbcL, rps4, psbA-trnH and trnL-F sequences from 5 new and 49 shared data; the results showed that Dennstaedtia smithii is nested within Microlepia rather than Dennstaedtia. We further studied the morphological characters based on the phylogeny result and found that D. smithii is distinguished from other species of Dennstaedtia by spore ornamentation and the unconnected of grooves between rachis and pinna rachis. According to morphological and molecular phylogenetic studies, our results supported that D. smithii should be a new member of Microlepia and renamed Microlepia smithii (Hook.) Y.H. Yan. Finding hidden outliers can promote the consistency of morphological and molecular phylogenetic results, and make the systematic classification more natural.
