Osteoarthritis and rheumatoid arthritis (RA) are prevalent chronic joint disorders, with prevalence rates varying by sex. However, few studies have comprehensively documented the factors contributing to the sex-specific prevalence of osteoarthritis and RA, including sociological factors and the impact of the COVID-19 pandemic. This study aims to identify long-term trends in the sex-specific prevalence of osteoarthritis and RA from 2005 to 2021 while examining the factors that serve as vulnerabilities specific to each sex within the context of the COVID-19 pandemic. Data were collected from a nationally representative sample of 110,225 individuals through the Korea National Health and Nutrition Examination Survey from 2005 to 2021. The study included patients aged 19 years and older diagnosed with osteoarthritis or RA in South Korea. Data were analyzed using weighted trends to accurately represent the sample population, with a 95% CI. Weighted logistic and regression models were used to identify vulnerable groups at risk of osteoarthritis or RA during the pandemic to assess sex-specific trends. In total, 110,225 individuals (n=48,410, 43.92% male participants) were analyzed from 2005 to 2021, with prevalence rates remaining stable over time and higher in female than in male participants. Notably, during the pandemic, female participants aged 60 years and older exhibited a prevalence of osteoarthritis that was 4.92 times greater than male participants and a prevalence of RA that was 6.44 times greater (osteoarthritis: prevalence ratio [PR] 69.78, 95% CI 41.66-116.88; RA: PR 17.27, 95% CI 8.75-34.07). In terms of osteoarthritis, male participants did not show a significant association with BMI (PR 1.40, 95% CI 1.21-1.61; P=.47), whereas female participants exhibited a significantly higher vulnerability within the obese group (PR 1.68, 95% CI 1.55-1.83; P<.001). Regarding RA, lower education levels were associated with increased vulnerability, with male participants showing a greater risk than female participants (male participants: PR 2.29, 95% CI 1.61-3.27 and female participants: PR 1.50, 95% CI 1.23-1.84). This study reveals that women in South Korea have a higher prevalence of osteoarthritis and RA than men. Understanding these sex-specific trends and identifying vulnerability factors can enhance preventive efforts and patient care.

<bold>Introduction:</bold> The underlying mechanisms and factors contributing to Long COVID are poorly understood. A wide variety of symptoms have been reported several months after infection by COVID-19, including breathlessness, fatigue, brain fog and many more. <bold>Methods:</bold> During the early phase of the pandemic, we sought to investigate whether a mobile application (TIYGA ecosystem) could be used to capture data about the type, intensity (scale 1-10), and frequency of specific symptoms. We aimed to understand how to record the sequence of occurrence of new symptoms over time. <bold>Results:</bold> Thirteen participants volunteered from a Charity-led Respiratory Support Group. All participants signed a consent form and created anonymised accounts. The symptoms and interventions tracked by the app were individually personalised and chosen by the participants. There was a high burden of symptoms spanning multiple organ systems, the commonest presented in Figure 1A. The app (TIYGA ecosystem) tracked individual patient’s symptoms and provided healthcare professionals (HCPs) with data regarding severity and resolution of symptoms over time (Figure 1B). <fig><object-id>erj;64/suppl_68/PA4367/F1</object-id><object-id>F1</object-id><object-id>F1</object-id><graphic></graphic></fig> <bold>Conclusion:</bold> The app (TIYGA ecosystem) allows individualised monitoring on a longitudinal basis giving HCPs a rapid overview of progress and detail about changing specific symptom prevalence. This ecosystem provides a unique digital interface that may enhance communication between patients and HCPs.

Traditional manufacturing units face a lot of challenges in coping with growing demand. With the more demand, maintaining the quality of the product is another challenge. Industry 4.0 can be utilized to meet the growing demand without sacrificing the quality of the product. The aim of this research is to analyse the improvement in production capabilities when implementing smart manufacturing. Woodford Timber Products has streamlined its production processes and increased its operational efficiency by embracing innovative technology and techniques. The digitisation of manufacturing processes through sophisticated software is capable of designing, rendering, analysing, and converting to machine language for multi axis CNC machines. The organisation derives significant insights from enormous volumes of data using product data management optimising manufacturing schedules, minimising waste, and improving product quality.

ABSTRACTMotivated by observations of localized electrostatic wavepackets by the Cassini – and (earlier) by Voyager 1 and 2 – mission(s) in Saturn’s magnetosphere, we have investigated the existence conditions and the dynamical evolution of localized multidimensional structures in the Saturnian dusty plasma environment. To this effect, we have adopted a plasma-fluid model for dust-ion acoustic excitations, taking into account the presence of a highly energetic (suprathermal, kappa-distributed) electron population in combination with massive dust dust particulates in the background. A multiple scales perturbation method was shown to lead to a Davey--Stewartson (DS) system of evolution equations, if one assumes perpendicular carrier wave propagation across the magnetic field (direction). The system is then shown to possess two regimes mainly, known in the literature as DS-I and DS-II. In the former case, if certain conditions are fulfilled, exponentially localized solutions are obtained, known as dromions. The combined effects of various physical parameters, such as the electron spectral index, the ambient magnetic field (strength), and the dust concentration, have been examined. A numerical investigation reveals that the dromion amplitude increases with higher dust concentration, whereas it decreases for lower κe (i.e. with an increase in the suprathermal electron population component). A stronger magnetic field results in higher amplitude but narrower dromions. Our results provide a comprehensive framework for modeling modulated electrostatic wavepackets, in direct comparison with experimental data in planetary environments, in Saturn’s magnetosphere and elsewhere.

Background: Whilst the 99th percentile is the recommended diagnostic threshold for myocardial infarction (MI), some guidelines also advocate the use of higher troponin thresholds to rule-in MI at presentation. It is unclear whether the magnitude or change in troponin concentration can differentiate causes of myocardial injury and infarction in practice. Hypothesis: Troponin concentration alone cannot to distinguish subtypes of myocardial infarction Methods: In a secondary analysis of a multi-centre randomized controlled trial, we identified 46,092 consecutive patients presenting with suspected acute coronary syndrome without STEMI. High-sensitivity troponin I concentrations at presentation and on serial testing were evaluated. The positive predictive value (PPV) and specificity were determined at the sex-specific 99th percentile upper reference limit (URL), and rule-in thresholds of 64 ng/L and 5-fold of the URL for a diagnosis of type 1 MI. Results: Troponin concentrations were similar at presentation in type 1 (median [IQR] 91 [30-493] ng/L) and type 2 MI (50 [22-147] ng/L), and in acute (50 [26-134] ng/L) and chronic (51 [31-130] ng/L) myocardial injury (Figure A). The 99th percentile and rule-in thresholds of 64 ng/L and 5-fold URL gave a PPV of 57% (95% confidence interval [CI] 56-58%), 59% (58-61%) and 62% (60-64%), and a specificity of 96% (96-96%), 96% (96-96%) and 98% (97-98%), respectively (Figure B). The absolute, relative and rate of change in troponin concentration was highest in patients with type 1 MI (P&lt;0.001 for all, Figure C). Discrimination improved when troponin concentration and change in troponin were combined compared to troponin concentration at presentation alone (area under curve, 0.661 versus 0.613). Conclusions: Troponin concentrations at presentation are insufficient to distinguish type 1 MI from other causes of myocardial injury or infarction in practice and should not guide management decisions in isolation.

Abstract Single and multilayer films of La0.67Sr0.33MnO3 and CoFe2O4 were deposited by spin‐coating. The all‐alkoxide precursors allowed inorganic gel films of extreme homogeneity to be formed and converted to phase pure complex oxides at low temperatures. La0.67Sr0.33MnO3 films were made with La‐ and Ca‐methoxy‐ethoxides and Mn19O12(moe)14(moeH)10 as precursors at 800 °C. The CoFe2O4 films were obtained at extremely low 275 °C, using a new CoFe2‐methoxyethoxide precursor. The decomposition and microstructural development on heating was described by TG, TEM, XRD and IR spectroscopy. XRD showed no spurious phases and the unit‐cell dimensions coincided quite well with literature values of the targeted phases. The structural, magnetic and electronic properties of these films established their phase purity and high quality with physical properties comparable to films deposited by physical deposition methods. The magnetic and magneto transport results are presented for single, bi‐ and tri‐ layer structures. The magnetically soft La0.67Sr0.33MnO3 layer was exchange coupled to the magnetically hard CoFe2O4 layer, giving rise to interesting switching behaviour in magnetism and magneto‐transport properties.

The coronavirus disease 2019 (COVID-19) was declared a global pandemic in early 2020. Due to the rapid spread of the virus and limited availability of effective treatments, health and social care systems worldwide quickly became overwhelmed. Such stressful circumstances are likely to have negative impacts on health and social care workers’ wellbeing. The current study examined the relationship between coping strategies and wellbeing and quality of working life in nurses, midwives, allied health professionals, social care workers and social workers who worked in health and social care in the UK during its first wave of COVID-19. Data were collected using an anonymous online survey (N = 3425), and regression analyses were used to examine the associations of coping strategies and demographic characteristics with staff wellbeing and quality of working life. The results showed that positive coping strategies, particularly active coping and help-seeking, were associated with higher wellbeing and better quality of working life. Negative coping strategies, such as avoidance, were risk factors for low wellbeing and worse quality of working life. The results point to the importance of organizational and management support during stressful times, which could include psycho-education and training about active coping and might take the form of workshops designed to equip staff with better coping skills.
