Objective: Systemic sclerosis (SSc) is a rare, chronic autoimmune disorder associated with disability, diminished physical function, fatigue, pain, and mental health concerns. We assessed minimal detectable changes (MDCs) of the Health Assessment Questionnaire–Disability Index (HAQ‐DI), Patient‐Reported Outcomes Measurement Information System‐29 Profile version 2.0 (PROMIS‐29v2.0) domains, and Patient Health Questionnaire (PHQ)‐8 in people with SSc. Methods: Scleroderma Patient‐Centered Intervention Network Cohort participants completed the HAQ‐DI, PROMIS‐29v2.0 domains, and PHQ‐8 at baseline assessments from April 2014 until August 2023. We estimated MDC95 (smallest change that can be detected with 95% certainty) and MDC90 (smallest change that can be detected with 90% certainty) with 95% confidence intervals (CIs) generated via the percentile bootstrapping method resampling 1,000 times. We compared MDC estimates by age, sex, and SSc subtype. Results: A total of 2,571 participants were included. Most were female (n = 2,241; 87%), and 38% (n = 976) had diffuse SSc. Mean (±SD) age was 54.9 (±12.7) years and duration since onset of first non‐Raynaud phenomenon symptom was 10.8 (±8.7) years. MDC95 estimate was 0.41 points (95% CI 0.40–0.42) for the HAQ‐DI, between 4.88 points (95% CI 4.72–5.05) and 9.02 points (95% CI 8.80–9.23) for the seven PROMIS‐29v2.0 domains, and 5.16 points (95% CI 5.06–5.26) for the PHQ‐8. MDC95 estimates were not materially different across subgroups. Conclusion: MDC95 and MDC90 estimates were precise and similar across age, sex, and SSc subtype groups. HAQ‐DI MDC95 and MDC90 were substantially larger than previous estimates of HAQ‐DI minimal important difference from several small studies. Minimally important differences of all measures should be evaluated in large studies using anchor‐based methods. [ABSTRACT FROM AUTHOR]

Contains fulltext : 294269.pdf (Publisher’s version ) (Open Access) Objective: Some individuals with systemic sclerosis (SSc) report positive mental health, despite severe disease manifestations, which may be associated with resilience, but no resilience measure has been validated in SSc. This study was undertaken to assess the validity, reliability, and differential item functioning (DIF) between English- and French-language versions of the 10-item Connor-Davidson Resilience Scale (CD-RISC-10) in SSc. Methods: Eligible participants were enrolled in the Scleroderma Patient-centered Intervention Network Cohort and completed the CD-RISC-10 between August 2022 and January 2023. We used confirmatory factor analysis (CFA) to evaluate the CD-RISC-10 factor structure and conducted DIF analysis across languages with Multiple Indicators Multiple Causes models. We tested convergent validity with another measure of resilience and measures of self-esteem and depression and anxiety symptoms. We assessed internal consistency and test–retest reliability using Cronbach's alpha and intraclass correlation coefficient (ICC). Results: A total of 962 participants were included in this analysis. CFA supported a single-factor structure (Tucker–Lewis index = 0.99, comparative fit index = 0.99, root mean square error of approximation = 0.08 [90% confidence interval (90% CI) 0.07, 0.09]). We found no meaningful DIF. Internal consistency was high (α = 0.93 [95% CI 0.92, 0.94]), and we found that correlations with other measures of psychological functioning were moderate to large (|r| = 0.57-0.78) and confirmed study hypotheses. The scale showed good 1-2-week test-retest reliability (ICC 0.80 [95% CI 0.75, 0.85]) in a subsample of 230 participants. Conclusion: The CD-RISC-10 is a valid and reliable measure of resilience in SSc, with score comparability across English and French versions. 02 mei 2023 10 p.

Experimental Psychopathology and Treatment ,Rehabilitation - Abstract
Explore trial participants’ and research team members’ perceptions of the impact of the videoconference-based, supportive care program (SPIN-CHAT Program) during early COVID-19 for individuals with systemic sclerosis (SSc). Data were collected cross-sectionally. A social constructivist paradigm was adopted, and one-on-one videoconference-based, semi-structured interviews were conducted with SPIN-CHAT Trial participants and research team members. A hybrid inductive-deductive approach and reflexive thematic analysis were used. Of the 40 SPIN-CHAT Trial participants and 28 research team members approached, 30 trial participants (Mean age = 54.9; SD = 13.0 years) and 22 research team members agreed to participate. Those who took part in interviews had similar characteristics to those who declined. Five themes were identified: (1) The SPIN-CHAT Program conferred a range of positive psychological health outcomes, (2) People who don’t have SSc don’t get it: The importance of SSc-specific programming, (3) The group-based format of the SPIN-CHAT Program created a safe space to connect and meet similar others, (4) The structure and schedule of the SPIN-CHAT Program reduced feelings of boredom and contributed to enhanced psychological health, (5) The necessity of knowledge, skills, and tools to self-manage SSc and navigate COVID-19. Participants’ and research team members’ perspectives elucidated SPIN-CHAT Program benefits and how these benefits may have been realized. Results underscore the importance of social support from similar others, structure, and self-management to enhance psychological health during COVID-19. clinicaltrials.gov (NCT04335279)IMPLICATIONS FOR REHABILITATIONThe videoconference-based, supportive care SPIN-CHAT Program enhanced psychological health amongst individuals affected by systemic sclerosis.SPIN-CHAT Program participants and research team members shared that being around similar others, program structure, and self-management support were important and may have contributed to enhanced psychological health.Further efforts are required to explore experiences within supportive care programs to better understand if and how psychological health is impacted.

- Abstract
Some individuals with systemic sclerosis (SSc) report positive mental health, despite severe disease manifestations, which may be associated with resilience, but no resilience measure has been validated in SSc. This study was undertaken to assess the validity, reliability, and differential item functioning (DIF) between English‐ and French‐language versions of the 10‐item Connor‐Davidson Resilience Scale (CD‐RISC‐10) in SSc. Eligible participants were enrolled in the Scleroderma Patient‐centered Intervention Network Cohort and completed the CD‐RISC‐10 between August 2022 and January 2023. We used confirmatory factor analysis (CFA) to evaluate the CD‐RISC‐10 factor structure and conducted DIF analysis across languages with Multiple Indicators Multiple Causes models. We tested convergent validity with another measure of resilience and measures of self‐esteem and depression and anxiety symptoms. We assessed internal consistency and test–retest reliability using Cronbach's alpha and intraclass correlation coefficient (ICC). A total of 962 participants were included in this analysis. CFA supported a single‐factor structure (Tucker–Lewis index = 0.99, comparative fit index = 0.99, root mean square error of approximation = 0.08 [90% confidence interval (90% CI) 0.07, 0.09]). We found no meaningful DIF. Internal consistency was high (α = 0.93 [95% CI 0.92, 0.94]), and we found that correlations with other measures of psychological functioning were moderate to large (|r| = 0.57–0.78) and confirmed study hypotheses. The scale showed good 1–2‐week test–retest reliability (ICC 0.80 [95% CI 0.75, 0.85]) in a subsample of 230 participants. The CD‐RISC‐10 is a valid and reliable measure of resilience in SSc, with score comparability across English and French versions.

- Abstract
Loneliness has been associated with poorer health‐related quality of life but has not been studied in patients with systemic sclerosis (SSc). The current study was undertaken to examine and compare the psychometric properties of the English and French versions of the University of California, Los Angeles, Loneliness Scale‐6 (ULS‐6) in patients with SSc during the COVID‐19 pandemic. This study used baseline cross‐sectional data from 775 adults enrolled in the Scleroderma Patient‐Centered Intervention Network (SPIN) COVID‐19 Cohort. Reliability and validity of ULS‐6 scores overall and between languages were evaluated using confirmatory factor analysis (CFA), differential item functioning (DIF) through the multiple‐indicator multiple‐cause (MIMIC) model, omega/alpha calculation, and correlations of hypothesized convergent relationships. CFA for the total sample supported the single‐factor structure (comparative fit index [CFI] 0.96, standardized root mean residual [SRMR] 0.03), and all standardized factor loadings for items were large (0.60–0.86). The overall MIMIC model with language as a covariate fit well (CFI 0.94, SRMR 0.04, root mean square error of approximation 0.11). Statistically significant DIF was found for 3 items across language (βitem2= 0.14, P< 0.001; βitem4= –0.07, P= 0.01; βitem6= 0.13, P< 0.001), but these small differences were without practical measurement implications. Analyses demonstrated high internal consistency with no language‐based convergent validity differences. Analyses demonstrated evidence of acceptable reliability and validity of ULS‐6 scores in English‐ and French‐speaking adults with SSc. DIF analysis supported use of the ULS‐6 to examine comparative experiences of loneliness without adjusting for language.

Tt's likely to be a long time before drivers are redundant, but cars are taking on more and more tasks under computer control. As the Rinspeed Oasis is a concept car that, in reality, conforms to many of our preconceived ideas of what a driverless car will be like: An advanced driving assist system powered by artificial intelligence (Al) that continues to learn, accurate real time HD maps and a computer powerful enough to process all of this while showing your favourite film. It's feet up, not foot down to reach your destination. As 2021 approaches, just when and where will we see driverless cars on the road?

A smart city uses technology to automate and improve city services, ultimately making citizens' lives better. It describes a city full of connections, where information technology and the Internet of Things (IOT) is embedded into everyday life. The problem is, for each connection, there's a risk. Data is shared across networks that, if poorly encrypted, can be accessed. Each connection, however remote or seemingly innocuous, could provide an entry point for a hacker who could potentially manipulate that system for their own devices. Digital security experts like Cesar Cerrudo, CTO for IOActive Labs, have concerns about how robust this encryption is. Cerrudo points out that many use weak encryption algorithms, and others have poor key encryption generation or fixed keys that hackers can gain access to. It's not just fragile encryption or weak connection security - citizens in a smart city havea part to play too. Simple or shared passwords and lost memory sticks could potentially offer hackers the opportunity to access personal and business information that we hold. Malware can be stored within apps we freely download.

Receiving treatment for severe burns can be a traumatic experience. Wound cleaning and bandage changes cause pain that, even with opioids like morphine, 86 percent of patients still reported as excruciating. The paper reports that, whether it's making painful treatments more bearable, helping people to overcome mental health problems or supporting surgeons in their decisions, VR looks set to transform healthcare.

Today's devices are 'black boxes': to be admired, not repaired. However, this attitude is starting to change. Perhaps nowhere has technological development been more incredible than in mobile phones. Comparing old and new phones is a good illustration of how our seemingly insatiable appetite for new technology is often driven by fashion and style. It's not just phones, but cars, computers and even household appliances that are dictated by style, and it's this drive for smaller, sleeker and more aesthetically pleasing devices that makes working on them difficult. Sometimes products are designed to be difficult to access, sometimes it's a by-product of how they are made and engineered. Perhaps nowhere do owners feel more disempowered these days than when lifting the bonnet of a modern car. Most people would struggle to name most of the engine's parts, or even be able to spot them under the engine cover.

The main cause of traffic accidents is human error, but sorting out the tech challenges of driverless cars solves only half the problem. There are a multitude of reasons automated technology could benefit us. An estimated 90 per cent of accidents are caused by driver error.The idea of a self-driving vehicle isn't new. In the 1960s researchers at the Transport and Road Research Laboratory in Berkshire developed a'self-driving' Citroen DS car that was able to follow a series of magnetic cables embedded in the road. Since then, the industry has followed an evolutionary approach, gradually adding elements of automated technology to vehicles, like parking and lane sensors. Some of the technology, like telematics, has been around for over a decade. Telematics itself is a catch-all term for the converging of telecommunications technology with informatics. In recent times, this has led to a whole host of new developments, including parking sensors, GPS navigation, and automatic driver-assistance technology.

In the airline business, margins are everything. Large modern jet engines make up a huge proportion of an aircraft's weight, and the fuel used is a huge part of an operator's costs. A reduction in either could be the difference between profit and loss. Fluctuating oil prices, fierce competition and challenging carbon reduction targets set by regulators are all increasing pressure on manufacturers to improve engine efficiency. The world's 'big three' jet engine builders - General Electric (GE), Rolls-Royce and Pratt & Whitney - have all responded, unveiling new ranges of engines packed full of innovative technology and engineering. Speed here isn't the most important thing - in fact, the engines will operate at similar speeds to those in service today. It's all about improving efficiency, minimising the environmental impact and - most importantly - reducing operating cost. Using lightweight but ultra-tough composite materials, advanced high-pressure compressors, new planetary gearing systems and even 3D-printed components, competition is hotting up in a worldwide commercial engine market that in 2013 was estimated to have reached around $25bn.

- Abstract
Objectives: To compare fatigue in a large multinational systemic sclerosis (SSc) cohort to general population data and identify associated sociodemographic, lifestyle and SSc disease factors., Methods: Scleroderma Patient-centered Intervention Network Cohort participants completed the Patient-Reported Outcomes Measurement Information System-29 v2.0 fatigue domain. T-scores were compared with the USA general population (mean = 50; SD = 10). Multivariable linear regression was used to assess associations with sociodemographic, lifestyle, and disease-related variables., Results: Among 2,385 participants (mean age 54.9 (SD = 12.6) years, 87% female, 38% diffuse SSc), mean fatigue T-score was 54.6 (SD = 11.0); 438 (18%) reported mild fatigue, 641 (27%) moderate, and 180 (8%) severe fatigue. Fatigue was independently associated with sociodemographic factors age (-0.10 points per year, [95% CI -0.14;-0.07]), male sex (-1.67 points, [-2.96;-0.37]), non-married status (0.97 points [0.04; 1.89]), and country (reference USA; France -2.35 points [-3.48;-1.21] and UK 2.38 points [0.80; 3.97]), and lifestyle factors smoking (4.16 points [2.52; 5.80]), alcohol consumption (-0.18 points per drink per week [-0.28;-0.07]), and body-mass index (0.34 points per unit [0.27; 0.42]). Fatigue was associated with disease-related factors gastrointestinal involvement (4.21 points [2.99; 5.43]), digital ulcers (1.51 points, [0.25; 2.77]), moderate small joints contractures (1.41 points [0.13; 2.69]), rheumatoid arthritis (4.34 points [2.37-6.31]) and Sjögren's syndrome (1.89 points [0.23; 3.55]). When pain was included in the model, its association was large (2.19 points [2.03; 2.34]) and interstitial lung disease was also associated (1.21 points [0.42; 2.00])., Conclusions: In people with SSc, fatigue scores were substantially higher than the general population and associated with multiple disease factors including gastrointestinal involvement, several painful disease manifestations, and lung involvement., (© The Author(s) 2024.
