Published: August 2024

AbstractCeramic cutting inserts are a type of cutting tool commonly used in high-speed metal cutting applications. However, the wear of these inserts caused by friction between the workpiece and cutting inserts limits their overall effectiveness. In order to improve the tool life and reduce wear, this study introduces an emerging method called magnetic field-assisted batch polishing (MABP) for simultaneously polishing multiple ceramic cutting inserts. Several polishing experiments were conducted under different conditions, and the wear characteristics were clarified by cutting S136H steel. The results showed that after 15 min of polishing, the surface roughness at the flank face, edge, and nose of the inserts was reduced to below 2.5 nm, 6.25 nm, and 45.8 nm, respectively. Furthermore, the nose radii of the inserts did not change significantly, and there were no significant changes in the weight percentage of elements before and after polishing. Additionally, the tool life of the batch polished inserts was found to be up to 1.75 times longer than that of unpolished inserts. These findings suggest that the MABP method is an effective way to mass polish ceramic cutting inserts, resulting in significantly reduced tool wear. Furthermore, this novel method offers new possibilities for polishing other tools.

Abstract
Background
Management of idiopathic intracranial hypertension (IIH) is complex requiring contributions from multiple specialized disciplines. In practice, this creates considerable organizational and communicational challenges. To meet those challenges, we established an interdisciplinary integrated outpatient clinic for IIH with a central coordination and a one-stop concept. Here, we aimed to evaluate effects of this one-stop concept on subjective patient satisfaction and economic outcome in patients with IIH.

Methods
In a retrospective cohort study, we compared the one-stop era with integrated care (IC, 1-JUL-2021 to 31-DEC-2022) to a reference group receiving standard care (SC, 1-JUL-2018 to 31-DEC-2019) regarding subjective patient satisfaction (assessed by the Vienna Patient Inventory). Multivariable binary linear regression models were used to adjust for confounders.

Results
Baseline characteristics of the IC group (n = 85) and SC group (n = 81) were comparable (female: 90.6% vs. 90.1%; mean age: 33.6 vs. 32.8 years, educational level: ≥9 years of education 60.0% vs. 59.3%; located in Vienna 75.3% vs. 76.5%). Compared to SC, management within IC concept was associated with statistically significantly higher subjective patient satisfaction (beta = 0.93; p < 0.001) with the strongest effects observed in satisfaction with treatment accessibility and availability (beta = 2.05; p < 0.001). Subgroup analyses of patients with migration background and language barrier consistently indicated stronger effects of IC in these groups.

Conclusions
Interdisciplinary integrated management of IIH statistically significantly and clinically meaningfully improves patient satisfaction – particularly in socioeconomically underprivileged patient groups. Providing structured central coordination to facilitate and improve access to interdisciplinary management provides means to further improve outcome.
Income and consumption inequality trends: a comparative analysis between paid employees and the self-employed
Authors: Sadaf Sadaf 
Published: August 2024

AbstractThis paper aims to analyze trends in income and consumption inequality for paid and self-employed households and examine to what extent changes in aggregate consumption and income inequality can be explained by changes in their permanent and transitory components over time using data from the Italian Survey of Household Wealth (SHIW) covering the period 1989-2016. The results obtained from the Generalized Method of Moments (GMM) analysis reveal differences in consumption and income inequality, as well as their permanent and transitory components, between self-employed and payroll households. In particular, self-employed households experience higher levels of both income and consumption inequality, the increase in total income and consumption inequality is mainly driven by an increase in its transitory component. Furthermore, findings from other descriptive measures of inequality, such as the Gini coefficient, the variance of the log, 90th/10th, and 50th/10th percentile ratios, support the notion that income inequality is higher than consumption inequality across all groups, with self-employed households exhibiting a more pronounced difference.
A QR code-enabled framework for fast biomedical image processing in medical diagnosis using deep learning
Authors: Mashat Arwa 
Published: August 2024

AbstractIn the realm of disease prognosis and diagnosis, a plethora of medical images are utilized. These images are typically stored either within the local on-premises servers of healthcare providers or within cloud storage infrastructures. However, this conventional storage approach often incurs high infrastructure costs and results in sluggish information retrieval, ultimately leading to delays in diagnosis and consequential wastage of valuable time for patients. The methodology proposed in this paper offers a pioneering solution to expedite the diagnosis of medical conditions while simultaneously reducing infrastructure costs associated with data storage. Through this study, a high-speed biomedical image processing approach is designed to facilitate rapid prognosis and diagnosis. The proposed framework includes Deep learning QR code technique using an optimized database design aimed at alleviating the burden of intensive on-premises database requirements. The work includes medical dataset from Crawford Image and Data Archive and Duke CIVM for evaluating the proposed work suing different performance metrics, The work has also been compared from the previous research further enhancing the system's efficiency. By providing healthcare providers with high-speed access to medical records, this system enables swift retrieval of comprehensive patient details, thereby improving accuracy in diagnosis and supporting informed decision-making.
Differentiating low-risk thymomas from high-risk thymomas: preoperative radiomics nomogram based on contrast enhanced CT to minimize unnecessary invasive thoracotomy
Authors: Gao Chao , Yang Liping , Xu Yuchao , Wang Tianzuo , Ding Hongchao , Gao Xing , Li Lin 
Published: August 2024

Abstract
Background
This study was designed to develop a combined radiomics nomogram to preoperatively predict the risk categorization of thymomas based on contrast-enhanced computed tomography (CE-CT) images.

Materials
The clinical and CT data of 178 patients with thymoma (100 patients with low-risk thymomas and 78 patients with high-risk thymomas) collected in our hospital from March 2018 to July 2023 were retrospectively analyzed. The patients were randomly divided into a training set (n = 125) and a validation set (n = 53) in a 7:3 ratio. Qualitative radiological features were recorded, including (a) tumor diameter, (b) location, (c) shape, (d) capsule integrity, (e) calcification, (f) necrosis, (g) fatty infiltration, (h) lymphadenopathy, and (i) enhanced CT value. Radiomics features were extracted from each CE-CT volume of interest (VOI), and the least absolute shrinkage and selection operator (LASSO) algorithm was performed to select the optimal discriminative ones. A combined radiomics nomogram was further established based on the clinical factors and radiomics scores. The differentiating efficacy was determined using receiver operating characteristic (ROC) analysis.

Results
Only one clinical factor (incomplete capsule) and seven radiomics features were found to be independent predictors and were used to establish the radiomics nomogram. In differentiating low-risk thymomas (types A, AB, and B1) from high-risk ones (types B2 and B3), the nomogram demonstrated better diagnostic efficacy than any single model, with the respective area under the curve (AUC), accuracy, sensitivity, and specificity of 0.974, 0.921, 0.962 and 0.900 in the training cohort, 0.960, 0.892, 0923 and 0.897 in the validation cohort, respectively. The calibration curve showed good agreement between the prediction probability and actual clinical findings.

Conclusions
The nomogram incorporating clinical factors and radiomics features provides additional value in differentiating the risk categorization of thymomas, which could potentially be useful in clinical practice for planning personalized treatment strategies.

Authors: Chen Hsin-Hua , Wu Chieh-Liang , Chao Wen-Cheng 
Published: August 2024

Abstract
Background
To investigate the association between maternal sepsis during pregnancy and poor pregnancy outcome and to identify risk factors for poor birth outcomes and adverse perinatal events.

Methods
We linked the Taiwan Birth Cohort Study (TBCS) database and the Taiwanese National Health Insurance Database (NHID) to conduct this population-based study. We analysed the data of pregnant women who met the criteria for sepsis-3 during pregnancy between 2005 and 2017 as the maternal sepsis cases and selected pregnant women without infection as the non-sepsis comparison cohort. Sepsis during pregnancy and fulfilled the sepsis-3 definition proposed in 2016. The primary outcome included low birth weight (LBW, < 2500 g) and preterm birth (< 34 weeks), and the secondary outcome was the occurrence of adverse perinatal events.

Results
We enrolled 2,732 women who met the criteria for sepsis-3 during pregnancy and 196,333 non-sepsis controls. We found that the development of maternal sepsis was highly associated with unfavourable pregnancy outcomes, including LBW (adjOR 9.51, 95% CI 8.73–10.36), preterm birth < 34 weeks (adjOR 11.69, 95%CI 10.64–12.84), and the adverse perinatal events (adjOR 3.09, 95% CI 2.83–3.36). We also identified that socio-economically disadvantaged status was slightly associated with an increased risk for low birth weight and preterm birth.

Conclusion
We found that the development of maternal sepsis was highly associated with LBW, preterm birth and adverse perinatal events. Our findings highlight the prolonged impact of maternal sepsis on pregnancy outcomes and indicate the need for vigilance among pregnant women with sepsis.
Significant association between methyl mercury level and latent tuberculosis infection risk: a cross-sectional study
Authors: Hua Hai-bo , Wang Hui-jie 
Published: August 2024

Abstract
Objectives
This cross-sectional study aimed to explore the association between methyl mercury (MeHg) level and latent tuberculosis infection (LTBI) risk based on the data from National Health and Nutrition Examination Survey (NHANES 2011–2012).

Methods
A total of 5243 participants with 20 variables were enrolled. The importance of these variables on TB infection was first ranked by XGBoost and Random Forest methods. Then the association between MeHg level and infection risk was evaluated by restricted cubic spline, threshold effect, and generalized linear regression analyses. We also explored the factors correlated with the difference in MeHg level and finally conducted a mediation analysis to assess the mediating effect of MeHg in LTBI.

Results
521 participants were experiencing the LTBI, and 12 variables showed the differences between infection and non-infection groups (all P < 0.05). Of them, MeHg presented the highest importance on the LTBI. Restricted cubic spline (RCS) next revealed a significant non-linear correlation of MeHg with LTBI (all P < 0.05). Adjusted regression models further indicated their independent association (all P < 0.05), and infection risk increased with the increase of MeHg (P for trend < 0.05). We also found a significant turning point, and their association was significantly observed when MeHg > 5.75 µg/L (P < 0.05). In addition, asthma history was related to the difference in MeHg levels between LTBI and non-LTBI groups. Mediation analysis found that MeHg level partially mediated the association of asthma and LTBI risk (all P < 0.05).

Conclusions
Our study identified MeHg as an independent risk factor for LTBI risk. Their causal relationship needs more investigation to verify.

Authors: Tang Yao , Lu Wenhsuan , Zhang Yunfan , Wu Weiqiang , Sun Qiannan , Zhang Yuning , Liu Xiaomo , Liang Wei , Chen Si , Han Bing 
Published: August 2024

Abstract
Background
This study quantitatively analyzed the anatomic structure of the alveolar bone in the maxillary molar region at three potential locations for Temporary Anchorage Device (TAD) placement. Additionally, the study compared the variability in this region across different age groups, sagittal skeletal patterns, vertical facial types, and sexes.

Methods
In this retrospective cone-beam computed tomography study, the buccal alveolar bone was analyzed in the posterior molar area of 200 patients, the measurement items include buccal alveolar bone height, alveolar bone thickness, interradicular distance, and maxillary retromolar space.

Results
Buccal alveolar height was greatest in the U56 region. The interradicular space was largest in the U56 region and increased from the alveolar crest to the sinus floor. Buccal alveolar bone thickness was highest in the U67 region and generally increased from the alveolar crest to the sinus floor. The maxillary retromolar space gradually increased from the alveolar crest to the root apex.

Conclusions
TADs are safest when placed in the buccal area between the maxillary second premolar and the first molar, particularly at the 9 mm plane. The U67 region is the optimal safe zone for TAD placement for maxillary dentition distalization. TADs placement in adolescents can be challenging. Maxillary third molar extraction can be considered for maxillary dentition distalization.
Barriers and facilitators for strengthening physiotherapy services in Nepal: perspectives from physiotherapists and health providers
Authors: Shakya Nishchal Ratna , Emén Amanda , Webb Gillian , Myezwa Hellen , Karmacharya Biraj Man , Stensdotter Ann-Katrin 
Published: August 2024

Abstract
Background
Physiotherapy provides non-invasive and non-pharmaceutical intervention for curative, rehabilitation and preventative purposes. Physiotherapy is also a central provider of health promotion. As the global burden of non-communicable diseases and chronic health conditions is rising, the importance of physiotherapy services increases. Unfortunately, physiotherapy services in low- and middle-income countries (LMICs) are generally unsatisfactory. In Nepal, the earthquake in 2015 and the COVID pandemic have clearly illuminated the importance of physiotherapy.

Objective
This qualitative study aimed to identify barriers and facilitators at different system levels for strengthening physiotherapy services in Nepal.

Methods
Forty semi-structured individual interviews were performed with different health providers. Transcribed interviews were assessed with thematic analysis. A five-level socioecological framework conceptualised multilevel determinants of barriers and facilitators.

Results
The study revealed various factors that were potential barriers and facilitators across five different levels, namely individual (taking the lead, need for advocacy), interpersonal (lack of recognition and autonomy, networking for referrals and coordination), community (lack of knowledge and awareness, social and family support), organisational (accessibility, workplace and clinical practice, educational opportunities, role of organisations and rehabilitation centres), and public policy level (planning and implementation of policies and programs, medical hegemony, priorities). Government officials, local leaders, and clinicians, half of whom were physiotherapists, agreed on many of the same issues, where a lack of awareness of what physiotherapy is and knowledge about what physiotherapists do was central.

Conclusions
The results provide information for the development of physiotherapy by pointing out key elements that need attention. Our broad and structured investigation strategy is applicable to others for a comprehensive analysis of barriers and facilitators for physiotherapy services.

Authors: Quilis Neus , Mesa-del-Castillo Bermejo Pablo , Boix Paula , Juanola Oriol , Bernabeu Pilar , Francés Rubén , Andrés Mariano 
Published: August 2024

Abstract
Objectives
To measure regulatory T cell (Treg) levels in the peripheral blood of children with juvenile idiopathic arthritis (JIA) and analyse the association of this measure with disease activity, quality of life, adjustment of treatment, and hospitalisation.

Methods
We conducted a two-phase study (cross-sectional and prospective), including consecutive children with a JIA diagnosis according to ILAR criteria. Our independent variables were Tregs, Th1, Th2, and cytokines in peripheral blood, and our dependent variables in the cross-sectional phase were arthritis category, JIA activity, and patient-reported outcomes. To test associations, we used Spearman’s correlation coefficient and the Mann-Whitney U test. In the prospective phase, we explored the probability of treatment adjustment and hospitalisation for JIA during follow-up according to Tregs levels at baseline, using Cox proportional regression.

Results
Our sample included 87 participants (median age 11 years, 63.2% girls). Tregs were not associated with most variables of interest. However, we found that higher Tregs concentration was associated with lower erythrocyte sedimentation rate (ESR) and better subjective disease status and course, while higher IL-10 and TGF-β levels were associated with lower ESR, less pain, and better subjective disease status We found no association between Tregs and treatment adjustments or hospitalisation.

Conclusions
Higher baseline Treg levels in the peripheral blood of children with JIA may be associated with reduced disease activity and better quality of life, though were not informative on the inflammatory progression on the follow-up.
Effects of a dual intervention (motor and virtual reality-based cognitive) on cognition in patients with mild cognitive impairment: a single-blind, randomized controlled trial
Authors: Buele Jorge , Avilés-Castillo Fátima , Del-Valle-Soto Carolina , Varela-Aldás José , Palacios-Navarro Guillermo 
Published: August 2024

Abstract
Background
The increase in cases of mild cognitive impairment (MCI) underlines the urgency of finding effective methods to slow its progression. Given the limited effectiveness of current pharmacological options to prevent or treat the early stages of this deterioration, non-pharmacological alternatives are especially relevant.

Objective
To assess the effectiveness of a cognitive-motor intervention based on immersive virtual reality (VR) that simulates an activity of daily living (ADL) on cognitive functions and its impact on depression and the ability to perform such activities in patients with MCI.

Methods
Thirty-four older adults (men, women) with MCI were randomized to the experimental group (n = 17; 75.41 ± 5.76) or control (n = 17; 77.35 ± 6.75) group. Both groups received motor training, through aerobic, balance and resistance activities in group. Subsequently, the experimental group received cognitive training based on VR, while the control group received traditional cognitive training. Cognitive functions, depression, and the ability to perform activities of daily living (ADLs) were assessed using the Spanish versions of the Montreal Cognitive Assessment (MoCA-S), the Short Geriatric Depression Scale (SGDS-S), and the of Instrumental Activities of Daily Living (IADL-S) before and after 6-week intervention (a total of twelve 40-minutes sessions).

Results
Between groups comparison did not reveal significant differences in either cognitive function or geriatric depression. The intragroup effect of cognitive function and geriatric depression was significant in both groups (p < 0.001), with large effect sizes. There was no statistically significant improvement in any of the groups when evaluating their performance in ADLs (control, p = 0.28; experimental, p = 0.46) as expected. The completion rate in the experimental group was higher (82.35%) compared to the control group (70.59%). Likewise, participants in the experimental group reached a higher level of difficulty in the application and needed less time to complete the task at each level.

Conclusions
The application of a dual intervention, through motor training prior to a cognitive task based on Immersive VR was shown to be a beneficial non-pharmacological strategy to improve cognitive functions and reduce depression in patients with MCI. Similarly, the control group benefited from such dual intervention with statistically significant improvements.
