AbstractThe relationship between iron metabolism and cardiometabolic risk factors has been scarcely studied in children, and the results are controversial. The objective of this study was to evaluate the association between iron parameters and lipid, glycemic and blood pressure alterations in the pediatric population. This was a cross-sectional study of 1954 children between 9 and 10 years of age in Madrid (Spain), participants in a longitudinal study of childhood obesity. Iron metabolism parameters, i.e., serum iron (Is), ferritin (Fs), transferrin (Tf) and transferrin saturation (STf) and lipid, glycemic and blood pressure profiles were evaluated. Odds ratios (ORs) were estimated using logistic regression models adjusted for sociodemographic characteristics, diet, physical activity, C-reactive protein and body mass index. Compared with the participants in the low Is and STf tertiles, those in the upper tertiles had a lower risk of low HDL-Chol (OR: 0.34; 95%CI: 0.17; 0.67) and OR: 0.44 (95%CI: 0.23; 0.84), respectively, and children in the upper Fs tertile had an OR of 2.07 (95%CI: 1.16; 3.68) for low HDL-Chol. Children in the highest Is and STf tertiles had a lower risk of prediabetes [OR: 0.63 (95%CI: 0.41; 0.97) and OR: 0.53 (95%CI: 0.34; 0.82)] and insulin resistance (IR) (OR: 0.37; 95%CI: 0.22; 0.64), and those in the upper Tf tertile had a higher risk of IR (OR: 1.90; 95%CI: 1.16; 3.12). An increased risk of hypertension was found only in children in the upper Fs tertile (OR: 1.46; 95%CI: 1.01; 2.13). Conclusions: Biomarkers of iron metabolism are associated with cardiometabolic alterations in the pediatric population, with a variable direction and magnitude depending on the indicators used.

What is Known:• Iron metabolism is related to important cardiometabolic alterations such as metabolic syndrome and its components.• Association between biomarkers of iron status and cardiometabolic risk have been less explored in children.

What is New:• Biomarkers of iron metabolism are associated with cardiometabolic alterations in the pediatric population.• Iron parameters in the pediatric population could be of great help to detect and prevent cardiometabolic abnormalities early.

Abstract
Objective
The C3 & C7 dome-hybrid open-door laminoplasty was proven to be an effective treatment for multi-levels cervical spondylotic myelopathy (CSM). However, its superiority over traditional unilateral open-door laminoplasty (UOLP) remains questionable, and no studies have compared the efficacy of this technique with traditional UOLP. This study aimed to compare the effectiveness of C3 & C7 dome-hybrid open-door laminoplasty with traditional UOLP in treating multi-levels CSM.

Methods
A retrospective study of multi-levels CSM with laminoplasty was performed, including 35 cases of traditional UOLP and 27 cases of C3 & C7 dome-hybrid open-door laminoplasty. Radiographic evaluation parameters and clinical outcomes were recorded to evaluate the surgical effectiveness.

Results
There was no significant difference in demographic baseline parameters. At the final follow-up, the C2–C7 Cobb angle of the modified group was significantly greater than that of the traditional group (p = 0.026). Meanwhile, the C2–C7 SVA of the modified group was significantly smaller than that of the traditional group (p = 0.009). Clinical outcomes such as VAS, NDI, and SF-12 scores, improved significantly in the modified group compared to the traditional group, while the JOA scores had no significant difference in both groups. There was no significant difference in the overall rate of complications between the two groups.

Conclusion
Both techniques have satisfactory outcomes in treating multi-levels CSM. Comparing with traditional UOLP, C3 & C7 dome-hybrid open-door laminoplasty has a greater superiority in reducing postoperative neck pain and maintaining the cervical sagittal alignment. It is proven to be a feasible management for patients with multi-levels CSM.

ZusammenfassungDer Brückner-Test (Durchleuchtungstest) ist eine einfache und effiziente Untersuchungsmethode zur Detektion amblyogener Risikofaktoren. Visusrelevante Medientrübungen und Veränderungen am Augenhintergrund, sowie aus größerer Untersuchungsentfernung auffallende Refraktionsfehler können rasch und sensitiv erkannt werden. Der Brückner-Test kann keinesfalls eine augenärztliche Untersuchung ersetzen, stellt aber eine ausgezeichnete Screeningmethode für Kinderärzte und Allgemeinmediziner dar, um frühzeitig organische Augenerkrankungen und Ambylopien zu entdecken und einer raschen Behandlung zuzuführen.
Out-of-pocket expenditure, need, utilisation, and private health insurance in the Australian healthcare system
Authors: Ludlow Timothy , Fooken Jonas , Rose Christiern , Tang Kam Ki 
Published: October 2023

AbstractDespite widespread public service provision, public funding, and private health insurance (PHI), 20% of all healthcare expenditure across the OECD is covered by out-of-pocket expenditure (OOPE). This creates an equity concern for the increasing number of individuals with chronic conditions and greater need, particularly if higher need coincides with lower income. Theoretically, individuals may mitigate OOPE risk by purchasing PHI, replacing variable OOPE with fixed expenditure on premiums. Furthermore, if PHI premiums are not risk-rated, PHI may redistribute some of the financial burden from less healthy PHI holders that have greater need to healthier PHI holders that have less need. We investigate if the burden of OOPE for individuals with greater need increases less strongly for individuals with PHI in the Australian healthcare system. The Australian healthcare system provides public health insurance with full, partial, or limited coverage, depending on the healthcare service used, and no risk rating of PHI premiums. Using data from the Household, Income and Labour Dynamics in Australia survey we find that individuals with PHI spend a greater share of their disposable income on OOPE and that the difference in OOPE share between PHI and non-PHI holders increases with greater need and utilisation, contrary to the prediction that PHI may mitigate OOPE. We also show that OOPE is a greater concern for poorer individuals for whom the difference in OOPE by PHI is the greatest.
Mikhail Bakhtin and Lev Shestov on Dostoevsky: the unfinalized dialogue
Authors: Ogden Marina G. 
Published: October 2023

AbstractBakhtin’s view of the history of the novel, through the lens of Dostoevsky’s writing in his famous study on Dostoevsky’s poetics (1963), has had a significant impact on the way we read Dostoevsky today. On the other hand, Shestov’s original explorations of the human soul, which were drawn on his reading of Dostoevsky and made a lasting impression on his contemporaries, are still relatively unknown to the English-speaking reader. Having traced the history of the regenerations of Dostoevsky’s convictions in his earlier works, in his mature writings Shestov proposed that at a time of deep crisis the human mind may acquire a new dimension, which lies beyond the limits of the comprehensible and the explicable. Building on his analysis of Dostoevsky’s life and work, a transformative shift in Shestov’s own worldview, led to significant alterations in his reading of Dostoevsky in the final years of his life.In this essay, as I draw the two thinkers into a dialogue, I try to look beyond the obvious differences in the two philosophers’ views (though I acknowledge them) and, with respect to both thinkers’ outstanding contributions to twentieth-century European culture, I attempt to discover a number of key developing points in their views derived from their shared love of Dostoevsky’s art. Contrasting Shestov’s interpretation of Dostoevsky to that of Bakhtin’s, I argue that despite their different methods, standpoints, and philosophical views, and despite the seemingly antagonizing nature of their observations, Bakhtin and Shestov arrived at a number of conclusions, which contributed to our present understanding of Dostoevsky’s worldview.

AbstractThe introduction of robotics in orthopedic surgery has led to improved precision and standardization in total knee arthroplasty (TKA). Clinical benefits of robotic versus manual TKA have been well established; however, evidence for economic and healthcare resource utilization outcomes (HRU) is lacking. The primary objective of this study was to compare economic and HRU outcomes for robotic and manual TKA. The secondary objective was to explore comparative robotic and manual TKA pain and opioid consumption outcomes. Multi-database literature searches were performed to identify studies comparing robotic and manual TKA from 2016 to 2022 and meta-analyses were conducted. This review included 50 studies with meta-analyses conducted on 35. Compared with manual TKA, robotic TKA was associated with a: 14% reduction in hospital length of stay (P = 0.022); 74% greater likelihood to be discharged to home (P < 0.001); and 17% lower likelihood to experience a 90-day readmission (P = 0.043). Robotic TKA was associated with longer mean operating times (incision to closure definition: 9.27 min longer, P = 0.030; general operating time definition: 18.05 min longer, P = 0.006). No differences were observed for total procedure cost and 90-day emergency room visits. Most studies reported similar outcomes for robotic and manual TKA regarding pain and opioid use. Coupled with the clinical benefits of robotic TKA, the economic impact of using robotics may contribute to hospitals’ quality improvement and financial sustainability. Further research and more randomized controlled trials are needed to effectively quantify the benefits of robotic relative to manual TKA.
Does Democracy Matter for Lifespan Inequalities? Regime Type and Premature Mortality by Sex
Authors: Salazar Ana Ortiz , Rodríguez Javier , Salayeva Rena , Rogers Melissa 
Published: October 2023

Abstract Reductions in premature mortality are widely attributed to economic, educational, and medical factors. This study contributes to our understanding of the influence of political factors in preventing early death and gender inequalities in health outcomes. We analyze data from life tables of the World Health Organization, 2000–2015, to estimate the annual, sex-specific standard deviation of the age-at-death distribution across 162 countries. We apply dynamic panel model analyses to assess the association between political liberalization and inequalities in premature mortality. Our findings show reduced inequalities in premature mortality in liberal democracies, with men benefiting disproportionately. We theorize that liberal democracy may motivate governments to respond to citizens’ desires for policies that improve health and reduce risks. As democratic liberalization increases, premature mortality falls for men, which may be accounted for in part by reduced male mortality from injuries. Reductions in premature mortality for women appear to stem primarily from improvements in maternal mortality across regime types. Our findings support the idea that democratization may provide public health benefits, especially for male citizens.
Virtual Ethnography of Female Migrants: a WhatsApp Group as a Support Tool During Their Migration Process

Published: October 2023

AbstractThis research aimed to describe the use and functionality that migrant women provide to social networks and the role they play in the social integration of migrant women. Using a qualitative methodology design, a virtual ethnography approach, and with the support of ATLAS, this research analyses 863 discursive threads of a WhatsApp group comprised of 123 migrant women belonging to an association related to the social and labour integration of the migrant population. The results indicate that the WhatsApp group is a reliable source of information as well as spaces of solidarity and emotional support among women who experience similar situations during the migration process. The originality of these results is that they provide insight into the uses of social networks by migrant women, on which there is little research, through observations in a WhatsApp group. Organisations working with migrant women should rethink the functionalities of these social networks and the importance of these tools in improving the social and labour integration of migrant women.
Need for cognitive closure and desire for cultural tightness mediate the effect of concern about ecological threats on the need for strong leadership
Authors: Contu Federico , Ellenberg Molly , Kruglanski Arie W. , Pantaleo Giuseppe , Pierro Antonio 
Published: October 2023

AbstractThe present research utilizes an evolutionary framework to investigate the process underlying the recent rise of several populist, “strongmen” leaders. Specifically, we propose that when people experience contingent (i.e., impending) ecological threats, their need for cognitive closure is activated, making them desire strong rules (i.e., a tight society) and to be guided by a strong leader. Further, we hypothesize that desire for cultural tightness, once activated by need for cognitive closure, augments peoples’ need for strong leaders. In two studies, we tested our hypotheses with respect to two of the most salient ecological threats currently affecting Europeans, namely COVID-19 (Study 1) and the war in Ukraine (Study 2). Results supported all our hypotheses, thereby shedding light on psycho-motivational underpinnings (i.e., need for cognitive closure and desire cultural for tightness) of the rise of populist leaders. Results thus corroborate the idea that populist leaders can use ecological threats-related uncertainty to maintain or gain power, and that ecological threats could bring to an alignment with right-wing ideas of people’s political attitudes.
Elaborating the Relations Amongst Workers’ Learning, Innovations and Well-Being

Published: October 2023

AbstractElaborating the relations amongst workers’ learning, innovations and well-being is essential for achieving two important and dual goals in contemporary work life. The first is individuals’ ongoing learning that underpins their employability and can respond to new challenges and emerging occupational and workplace requirements. The second comprises workers’ remaking and transforming workplace practices, processes and outcomes (i.e., workplace innovations) in response to these challenges, and through them sustaining workplaces’ productivity and viability. These dual processes of individuals’ learning and remaking of practice co-occur and warrant understanding and supporting and promoting to exercise them optimally in achieving these dual goals. We aim to illuminate and elaborate these dual learning and innovations from the results of two studies of small to medium size Singaporean enterprises using interviews and observations. Framed by considerations from cultural psychology, work practice and well-being theorising, the dualities of workplace affordances (i.e., opportunities provided by workplaces) and individual engagement (i.e., how workers elect to engage and learn from these opportunities) are used to propose how workers’ worklife learning and workplace innovations can arise reciprocally. In conclusion, sets of curriculum and pedagogic practices that can be exercised in work settings are advanced.

Published: October 2023

AbstractThe Breast Reconstruction Risk Assessment (BRA) score is a tool for the prediction of the risk of complications in breast surgery, elaborated in 2014. This score assesses the risk of surgical complications related to each type of breast reconstruction technique. The purpose of this study was to evaluate the effectiveness of using the calculator on patients who underwent prosthetic breast reconstruction with submuscular tissue expander or prepectoral prosthesis. Our retrospective study analyzed 92 patients whose data was entered into the calculator. The predicted and observed 1-year rates of overall surgical complications were compared, separately for both cohorts. Subsequently, the accuracy, the applicability, and the discrimination ability of the BRA score were assessed using statistical analysis. In the two-stage subpectoral reconstruction group, Mann–Whitney U test showed a statistically significant difference in BRA-score values between the patients who developed complications compared to the patients who had no complications (p-value < 0.02). Moreover, the score has an excellent discrimination ability (AUC = 0.9), and a cutoff of overall surgical complication rate was found to be between 17 and 18%. For the one-stage prepectoral prosthetic reconstruction group, the BRA score tool was unable to discriminate between patients with complications and patients without complication. Our results suggest that the BRA score can accurately identify patients with risk of complications following two-stage subpectoral breast reconstruction. Moreover, we believe it is possible to identify a risk rate cutoff of overall surgical complications that may potentially help physicians select the safest surgical strategy.
Affordances of Virtual Learning Environments to Support Mathematics Teaching
Authors: Trgalová Jana , Tabach Michal 
Published: October 2023

AbstractThe slow uptake of technology by mathematics teachers is in contrast with the rapid growth in the availability of different digital resources specifically designed to help teaching and learning mathematics. We refer to platforms that were designed to permit for mathematical communication between multiple users. We seek to explore the affordances of such digital platforms to support mathematics teachers who wish to integrate technology as part of their practice, when planning and enacting technology-based mathematical activity. Specifically, we ask: What are the affordances and constraints of the platforms that may support instrumentation and instrumentalization processes leading to the development of teacher’s didactic instrument for planning and enacting a mathematical activity in a digital environment? The four platforms we chose for analysis are STEP, DESMOS, WIMS and Labomep. Our analysis shows on the one hand that the platforms afford support to the teacher while enacting technology-based mathematics activities. On the other hand, we suggest several components of didactic instrumental genesis that mathematics teachers need to develop in order to take benefit from digital platform affordances. These components include the ability to base decision-making on data gathered and visualised in dashboard embedded in learning management systems.
Robust monocular object pose tracking for large pose shift using 2D tracking
Authors: Wang Qiufu , Zhou Jiexin , Li Zhang , Sun Xiaoliang , Yu Qifeng 
Published: October 2023

AbstractMonocular object pose tracking has been a key technology in autonomous rendezvous of two moving platforms. However, rapid relative motion between platforms causes large interframe pose shifts, which leads to pose tracking failure. Based on the derivation of the region-based pose tracking method and the theory of rigid body kinematics, we put forward that the stability of the color segmentation model and linearization in pose optimization are the key to region-based monocular object pose tracking. A reliable metric named VoI is designed to measure interframe pose shifts, based on which we argue that motion continuity recovery is a promising way to tackle the translation-dominant large pose shift issue. Then, a 2D tracking method is adopted to bridge the interframe motion continuity gap. For texture-rich objects, the motion continuity can be recovered through localized region-based pose transferring, which is performed by solving a PnP (Perspective-n-Point) problem within the tracked 2D bounding boxes of two adjacent frames. Moreover, for texture-less objects, a direct translation approach is introduced to estimate an intermediate pose of the frame. Finally, a region-based pose refinement is exploited to obtain the final tracked pose. Experimental results on synthetic and real image sequences indicate that the proposed method achieves superior performance to state-of-the-art methods in tracking objects with large pose shifts.

-orbit connecting lemma for dynamically coherent and plaque expansive partially hyperbolic diffeomorphisms with one-dimensional orientation preserving center bundle. To be precise, for such a diffeomorphism f, if a point y is chain attainable from x through pseudo-orbits, then for any neighborhood U of x and any neighborhood V of y, there exist true orbits from U to V by arbitrarily

Ironies of accomplishment: negative aspiration, economic resentment and the myth of the middle class on Nairobi’s new urban outskirts
Authors: Lockwood Peter 
Published: October 2023

AbstractExploring the ‘hollow’ character of middle-class status in contemporary Kenya, this article shows how upwardly mobile young Kenyans struggle to cope with the expectations for distribution that their displays of achievement create. Focusing on the urbanizing peripheries of Nairobi, it shows how accusations of envy (wivu) made about poorer friends and relatives reflect their anxieties about failing to act as the providers they are expected to be. Anticipation of the disappointment and resentment of their would-be dependants encourages them to withdraw from friendships and kinship relations in their home neighbourhoods, and seek instead an impersonal life in new urban enclaves closer to Nairobi. The avoidance of obligation is justified through discourses of individual effort and achievement, while poorer peers and relations are criticized for looking to rely on others. The article shows how such tensions over obligation and desires for withdrawal illuminate the fragility of Kenya’s emerging middle class and the ‘ironies of accomplishment’ – that their very precarity denies these Kenyans the respect and status they desire in their neighbourhood homes.
