Objectives Using electronic health records, we derived and internally validated a prediction model to estimate risk factors for long COVID and predict individual risk of developing long COVID. Design Population-based, retrospective cohort study. Setting Scotland. Participants Adults (≥18 years) with a positive COVID-19 test, registered with a general medical practice between 1 March 2020 and 20 October 2022. Main outcome measures Adjusted odds ratios (aORs) with 95% confidence intervals (CIs) for predictors of long COVID, and patients’ predicted probabilities of developing long COVID. Results A total of 68,486 (5.6%) patients were identified as having long COVID. Predictors of long COVID were increasing age (aOR: 3.84; 95% CI: 3.66–4.03 and aOR: 3.66; 95% CI: 3.27–4.09 in first and second splines), increasing body mass index (BMI) (aOR: 3.17; 95% CI: 2.78–3.61 and aOR: 3.09; 95% CI: 2.13–4.49 in first and second splines), severe COVID-19 (aOR: 1.78; 95% CI: 1.72–1.84); female sex (aOR: 1.56; 95% CI: 1.53–1.60), deprivation (most versus least deprived quintile, aOR: 1.40; 95% CI: 1.36–1.44), several existing health conditions. Predictors associated with reduced long COVID risk were testing positive while Delta or Omicron variants were dominant, relative to when the Wild-type variant was dominant (aOR: 0.85; 95% CI: 0.81–0.88 and aOR: 0.64; 95% CI: 0.61–0.67, respectively) having received one or two doses of COVID-19 vaccination, relative to unvaccinated (aOR: 0.90; 95% CI: 0.86–0.95 and aOR: 0.96; 95% CI: 0.93–1.00). Conclusions Older age, higher BMI, severe COVID-19 infection, female sex, deprivation and comorbidities were predictors of long COVID. Vaccination against COVID-19 and testing positive while Delta or Omicron variants were dominant predicted reduced risk.

Authors: Low Mei Peng , Cheah Jun-Hwa 
Published: November 2024

Background The COVID-19 pandemic being a systemic crisis shocked the world and underscored the critical need for organizations to reimagine, reallocate, and reposition their resources to ensure survival and resilience. An organization’s resources, particularly human capital, are crucial elements of its success and adaptability in the face of such challenges. The difficulties in obtaining external assistance during the pandemic have further highlighted the importance of innovative strategies like employee-centered CSR (ECCSR) in managing and optimizing organizational resources. Recent studies emphasize the strategic role of ECCSR in bolstering resilience, with a focus on leveraging human capital effectively. Objective This study addresses several key objectives. First, it seeks to establish the interrelation between the four types of organizational resources (i.e., economic, human, physical, and social capital) and organizational resilience. It also aims to unveil the connection between employee-centered CSR (ECCSR) and organizational resilience, as well as to examine the relationship between ECCSR and workplace well-being. Additionally, the study investigates the link between workplace well-being and organizational resilience, and lastly, it explores the mediating role of workplace well-being between ECCSR and organizational resilience. Methods This study utilized a quantitative research design and employed a purposive sampling technique. The direct and indirect relationships among organizational resources, organizational resilience, ECCSR, and workplace well-being were analyzed using a variance-based structural equation modeling approach. Results The results revealed that among the four types of organizational resources, human capital is the most vital resource for organizational resilience. The findings also affirmed the emerging importance of ECCSR for organizational resilience, directly and indirectly through workplace well-being. Conclusions The study concludes that in times of crisis when organizations think outside the box by reimagining their situation and reallocating internal resources, such as human capital, they can buffer external shocks. This approach enables organizations to reposition themselves to withstand challenges and develop a strategic competitive advantage. Additionally, the study finds that the presence of ECCSR can cultivate positive employee well-being and organizations can benefit from the reciprocal gains that help them navigate difficult times more effectively. Implementing ECCSR not only fulfills an organization’s role as a responsible employer but also fosters workplace well-being, ultimately strengthening organizational resilience.

Published: November 2024

The effects of rapid tempering on the microstructure and mechanical properties of 0.34C ultrafine bainitic steel were studied. Results indicate that the carbon atoms in bainitic ferrite gradually segregated to dislocations when tempered at 450°C. Cluster strengthening improved the yield strength of the steel and stabilized the retained austenite. At 650°C, most of the retained austenite was decomposed, and numerous carbides were precipitated. The yield strength of the steel was not reduced, but the plasticity and impact toughness were greatly reduced. The optimum temperature for rapid tempering was 550°C, and its microstructure and mechanical properties gradually changed with the extension of tempering time. The duration of tempering can be determined on the basis of specific requirements.

Published: November 2024

Background The Alberta Stroke Program Early Computed Tomography Score (ASPECTS) is a semi-quantitative tool for evaluating the extent and distribution of early ischemic changes. Purpose To assess the value of ASPECTS on non-contrast CT (NCCT), arterial-phase CT (APCT), or venous-phase CT (VPCT) in predicting the final infarct core (IC) on follow-up diffusion-weighted imaging (DWI) and the clinical outcomes of patients with acute ischemic stroke (AIS) after endovascular thrombectomy (EVT). Material and Methods In total, 120 patients with AIS who underwent EVT in our center were retrospectively enrolled. Correlations between CT-ASPECTS and follow-up DWI-ASPECTS were analyzed using Spearman's rank correlation coefficient. Mean differences and limit of agreement (LoA) between CT-ASPECTS and follow-up DWI-ASPECTS were assessed using the Bland–Altman plots. Multivariate logistic regression and receiver operating characteristic curve analyses were used to identify independent factors and evaluate their performances in predicting the clinical outcomes. Results VPCT-ASPECTS exhibited the highest correlation with follow-up DWI-ASPECTS (r = 0.846, P < 0.001), followed by APCT-ASPECTS (r = 0.613, P < 0.001) and NCCT-ASPECTS (r = 0.557, P < 0.001). The mean difference between VPCT-ASPECTS and follow-up DWI-ASPECTS was 0.0 (limit of agreement = −2.1 to 2.1). National Institute of Health Stroke Scale (NIHSS) scores at admission (NIHSSpre) (odds ratio [OR]=1.162, 95% confidence interval [CI]=1.063–1.270; P = 0.001) and VPCT-ASPECTS (OR=0.728, 95% CI=0.535–0.991; P = 0.044) were the independent factors associated with clinical outcomes. The combined model integrating NIHSSpre and VPCT-ASPECTS exhibited an excellent performance in predicting good clinical outcomes (area under curve [AUC]=0.807; sensitivity=75.0%; specificity=72.3%). Conclusion VPCT-ASPECTS may be a promising imaging biomarker to predict the final IC and the clinical outcome of the patients with AIS after EVT.

Published: November 2024

Background AngioJet rheolytic thrombectomy is associated with a higher risk of acute kidney injury due to its potential for inducing mechanical harm and intravascular hemolysis. However, previous studies have focused on a single disease entity. Purpose To identify predictors associated with acute kidney injury after AngioJet rheolytic thrombectomy across a range of disease entities. Material and Methods A total of 95 patients who underwent AngioJet rheolytic thrombectomy between October 2018 and April 2023 were retrospectively reviewed. In total, 11 patients were excluded due to the absence of a postprocedural serum creatinine test within 72 h; finally, 84 patients were included. Acute kidney injury was defined as a ≥1.5-fold increase or ≥0.3 mg/dL rise in serum creatinine within 72 h after the procedure. Univariate and multivariate analysis were performed to identify risk factors for acute kidney injury. Results Technical and clinical success were achieved in all patients (84/84, 100%). Of the 84 patients (40 men [47.6%], 44 women [52.4%]; mean age = 67.2 ± 15.9 years), 15 (17.8%) had developed acute kidney injury. Multivariate analysis showed concurrent malignancy (odds ratio [OR] = 42.231, 95% confidence interval [CI] = 2.332–764.693; P = 0.011) and AngioJet rheolytic thrombectomy in arterial system (OR = 24.109, 95% CI = 1.319–440.551; P = 0.032) as statistically significant predictors of acute kidney injury. Conclusions AngioJet rheolytic thrombectomy is a potential risk for acute kidney injury. Concurrent malignancy and AngioJet rheolytic thrombectomy in the arterial system are independent predictors of acute kidney injury.

Published: November 2024

Objective This study aimed to investigate the relationship between falls and cognitive and balance problems in patients. Methods This retrospective observational study analyzed the medical records of 1010 older patients admitted to a convalescent rehabilitation ward. The primary endpoint was fall occurrence during ward stays. The main outcomes were the Mini-Mental State Examination (MMSE) and Standing Test for Imbalance and Disequilibrium (SIDE), with patients divided into groups of MMSE ≥28 and <28 and SIDE ≥2b and <2b. Results During ward stays, 220 patients (22%) fell. Estimating the fall risk of the MMSE ≥28 + SIDE ≥2b group compared to that of other groups revealed that only the MMSE <28 + SIDE <2b group had a significantly higher fall risk, with a hazard ratio [95% confidence interval] of 3.13 [1.51–6.46]. Conclusion Combined MMSE and SIDE assessment at ward admission facilitated the easy identification of individuals at high fall risk.

Purpose To describe an alternative technique used in massive post-traumatic cyclodialysis. Classic techniques such as direct cyclopexy are performed ab externo and entail a higher risk of endophthalmitis or ciliary body hemorrhage. Therefore we present a case report using combined sewing machine technique cyclopexy with transscleral diode cyclophotocoagulation for complete post-traumatic cyclodialysis. Patients Our patient is a 43-year-old woman who suffered a blunt trauma 9 months ago from an air-bag blunt in a car accident. Methods Technique report. Results Two weeks post-surgery, there has been an elevation in intraocular pressure (IOP), and the cyclodialysis has been resolved. Additionally, signs of macular hypotony, such as optic nerve head edema and vascular tortuosity, have disappeared. As anticipated, the disappearance of chorioretinal folds occurred later but has also been observed. Furthermore, the best corrected visual acuity has been improved and the induced hyperopia has been corrected from +5 (−1.75 × 20°) to +1.5 (−1.75 × 20°). Conclusions Combined sewing machine technique cyclopexy with transscleral diode cyclophotocoagulation for complete post-traumatic cyclodialysis could be an alternative surgical improvement to both direct and indirect cyclopexy. It entails fewer complications, such as endophthalmitis, and offers favorable aesthetic outcomes along with enhanced intraoperative visualization.

Background Aneurysm treatments are crucial to minimize the rupture risk. The underlying molecular processes mediating cellular remodeling, endothelialization, and aneurysm healing following endovascular treatment are poorly understood. The current study aims to explore circulating miRNA as a treatment and outcome-associated biomarkers in patients undergoing endovascular treatment. Methods Patients undergoing endovascular interventions for unruptured intracranial aneurysms, using either flow diverter placement or coil embolization, were enrolled. Blood samples were collected before the intervention and during a follow-up period between 6 and 18 months. Total mRNA/miRNA was isolated from plasma, followed by RNA-seq analysis. Gene Ontology analysis was used to identify pathways linked to altered miRNA expression. Results Twenty-three patients participated, with 13 (56.5%) undergoing flow diversion and 10 (43.5%) coil embolization. The median follow-up sample collection time was 10.70 months (SEM ± 1.32). No significant differences in angiographic occlusion were noted between intervention groups. Differentially expressed miRNAs were not identified between groups at baseline. However, at follow-up, 39 miRNAs were upregulated and 41 were downregulated, independent of intervention. Notably, three miRNAs (miR-4746-5p, miR-4685-3p, and miR-490-3p) were downregulated in the flow diversion group compared to the coil embolization group. Bioinformatics analysis revealed associations with upregulated fluid shear stress, p53, adherens junction pathways, along with downregulated apoptosis pathways. Conclusions This study suggests that fluid shear stress and apoptosis may influence aneurysm healing or thromboembolic events in flow diverter-treated patients. Further research is warranted to elucidate the functional significance of these findings in treatment outcomes, providing valuable insights for improved patient care in intracranial aneurysm management.
“A Beauty Full of Healing”: Black Aesthetics as Methodology
Authors: Abdi Kaha 
Published: November 2024

Sylvia Wynter calls for a rethinking of the aesthetics since our current system of knowledge, which is rooted in a positivist, biocentric framework, fails to recognize storytelling as an essential aspect of humanness. Similarly, bell hooks reminds us to see, not only through sight, but in a metaphysical way that heightens our awareness and understanding – expanding our ability to engage with reality through all of our senses. Thus, this paper explores the ways in which Black aesthetics serve as method-making practices in order to reclaim the imagination from modern thinking, particularly given that the narrative of modernity has been partially constructed on the myth that Black peoples lack culture, or, alternatively, that their cultural practices are primitive and monolithic. By asserting Blackness as a situating force, Black cultural practices underscore the agentic capacity of Black peoples to create and define their own realities, rather than being merely subjects of observation. What methods do we use, then, that can faithfully portray the subtleties of Black life?
Empowering junior doctors: A study on the feasibility and efficacy of ultrasound AAA screening in rural Australia
Authors: Koo Mei Ping Melody , Bookun Hansraj Riteesh 
Published: November 2024

Purposes Abdominal Aortic Aneurysm (AAA) screening via ultrasound in Caucasian males aged 65 and older has proven cost-effective in metropolitan areas. Evidence suggests that with adequate training, individuals without prior sonography experience can achieve accurate aortic measurements. This study evaluates the capability of junior doctors, after brief training, to conduct reliable AAA ultrasound screenings in a rural hospital setting, addressing the gap in speciality surgical services. Methods Three junior doctors participated in a 2-hour practical ultrasound training, subsequently performing scans on both inpatients and community volunteers at a regional hospital. The analysis focused on measurement discrepancies within a 5 mm clinically acceptable difference, scanning efficiency, and aneurysm detection accuracy. Results A total of 71 participants were included. Among the screenings, 81.7% fell within the clinically acceptable discrepancy range, with 72.7% accuracy in inpatient scans and 95.5% in volunteer scans. Measurement reproducibility improved significantly with the standardisation of ultrasound techniques, and there was excellent agreement among operators in detecting aneurysms. Notably, scanning efficiency improved from the inpatient group to the volunteer group with statistical significance. Conclusions Junior doctors demonstrated the ability to efficiently and reproducibly measure the infrarenal aortic diameter at a level comparable to experienced sonographers after only 2 hours of training. A single day of supervised practice is recommended to ensure standardised ultrasound technique. This approach offers a practical, cost-effective supplement to specialist radiology services in rural areas, enhancing access to critical screening procedures without proposing the replacement of professional sonographers.

Exploring the influential factors and improvement strategies for digital information literacy among the elderly: An analysis based on integrated learning algorithms
Authors: Kong Haiyan , Wang Xinyu 
Published: November 2024

Objective Despite previous research identifying factors such as age, education level, income, and interest in technology that influence digital literacy among the elderly, this study attempts to use machine learning algorithms, especially ensemble learning algorithms, to predict and identify the key factors that affect the digital information literacy of the elderly, so as to propose effective strategies to improve the elderly's ability to utilize digital information and better integrate into the digital society. Methods This study used primary data on older adults from the Digital Divide Survey 2022 conducted by the Korea National Information Society Agency. A predictive model was built, and 15 variables that were highly important in predicting digital information literacy were identified. Prediction accuracy was assessed using an ensemble of algorithms including Random Forest, LGBM, XGBoost, AdaBoost, and CatBoost. Results The study found that in addition to demographic factors and personal technology use ability factors, relationship support factors and social digital environment factors are also important predictors of digital information literacy for the elderly. Among different predictive models, the CatBoost model, based on boosting ensemble, exhibited the highest predictive accuracy at 86.2%, followed by Random Forest (85.5%), LGBM (85.2%), XGBoost (84.5%), and AdaBoost (83.8%). The predictive accuracies of these models were higher than those of traditional machine learning models, indicating the effectiveness of ensemble learning algorithms in predicting digital information literacy among the elderly. Conclusions The academic significance of this study lies in the application of artificial intelligence technologies to the social sciences, specifically demonstrating the effectiveness of ensemble learning algorithms in predicting factors influencing the digital literacy levels of the elderly. This approach provides a novel and powerful tool for addressing complex social issues. The practical significance lies in the proposed strategies for improving the digital literacy of the elderly based on the research results, including education and training, social relationship support, social participation, technical support, and policy formulation, aiming to help the elderly better adapt to the digital environment, narrow the digital divide, and enhance the elderly's sense of participation and happiness in the digital society.
