Study design: A cohort of 384 Spanish workers included in a Post COVID-19 condition or persistent COVID-19 multicenter research was utilized. Place and Duration of Study: This cohort was enlisted in four hospitals (Hospital Universitario 12 de Octubre, Madrid;Hospital Universitario Virgen Macarena, Sevilla, Andalucía;Hospital Universitario Gregorio Marañón, Madrid and Complejo Asistencial Universitario de Salamanca, Castilla y León), since 2021 until 2022. Methodology: 384 Spanish workers (176 men and 208 women;aged 20 to 70 years) with Post COVID-19 condition or persistent COVID-19 were included. Descriptive analysis of primary scores was conducted. Given the non-normal distribution of data, the Mann-Whitney and Kruskal-Wallis tests were employed. Spearman and Kendall correlations were employed to assess the relationship between WAI and WAS, also used weighted Kappa to estimate the degree agreement between WAI and WAS. Logistic regression models were utilized to study determinants influencing WAI and WAS, categorized as poor or moderate. Results: WAI had an average score of 32.98 (SD = 10.28), whereas WAS had an average of 5.95 (SD = 2.77). Significant differences were observed in both WAI and WAS across the same variables. Strong and statistically significant correlations were evident between WAI and WAS (rs = 0.83, p < 0.001). All the variables used in the logistic regression model (gender, the sector employment, and previous chronic diseases) were statistically significant in both questionnaires. Conclusion: WAS questionnaire could be used as a tool for reliable assessment of work ability among Spanish workers with Post COVID-19 condition or Persistent CO-VID-19.展开更多

Despite marked improvements in quality of life and functional status, a substantial proportion of LT recipients are unable to resume gainful employment. Unemployment forms a threat to physical and psychosocial health, and impairs LT cost-utility through lost productivity. In studies published after year 2000, the average postLT employment rate is 37%, ranging from 22% to 55% by study. Significant heterogeneity exists among studies. Nonetheless, these employment rates are lower than in the general population and kidneytransplant population. Most consistent employment predictors include pre-LT employment status, male gender, functional/health status, and subjective work ability. Work ability is impaired by physical fatigue and depression, but affected also by working conditions and society. Promotion of post-LT employment is hampered by a lack of interventional studies. Prevention of pre-LT disability by effective treatment of(minimal) hepatic encephalopathy, maintaining mobility, and planning work adjustments early in the course of chronic liver disease, as well as timely post-LT physical rehabilitation, continuous encouragement, self-efficacy improvements, and depression management are key elements of successful employment-promoting strategies. Prolonging LT recipients' working life would further strengthen the success of transplantation, and this is likely best achieved through multidisciplinary efforts ideally starting even before LT candidacy.展开更多

A regional pension insurance introduced a Return To Work (RTW) strategy for insurants with chronic conditions. The objective was to identify the degree of implementation of work related measures in medical rehabilitation and the extent of RTW outcomes. Methods: 5883 insurants were considered. Severe Restriction of Work Ability (SRWA), Work-related Medical Rehabilitation (WMR), and Case Management (CM) were examined for 2008 and 2012. An Index of Employment status (IoE) was used in a logistic regression. Results: Utilization of WMR raised from 12.3% in 2008 to 66.1% in 2012. The proportion of insurants with SRWA and WMR grew from 8% up to 40.1%. In 2008, 14.7% of insurants with SRWA received WMR;in 2012, it grew to 76.6%. On the other hand, in 2012 26% got WMR without SRWA and 12.2% had SRWA and got no WMR. CM was not conducted in 2008 but reached 20.2% in 2012. Across all indications, WMR resulted in positive RTW as measured by IoE: OR = 0.75 (KI-95%: 0.67 - 0.86). Conclusion: WMR was successfully implemented according to the German guideline. There is a need to optimize the linkage between SRWA and WMR and CM to provide need-based care.展开更多

The ideological work ability of college counselors is related to the ideological security of colleges and universities, and to the realization of the goal of talent cultivation in Socialist Colleges and universities. College counselors, as the fresh force of ideological education for college students, are the organizers, implementers and guides of the daily ideological and political education and management of College students. In order to do a good job in the ideological work of colleges and universities under the new situation, as the counselor of the backbone of ideological and political work in colleges and universities, the ability to carry out ideological work is directly related to the effectiveness of this work.

The effects of spheri- cal light-weight aggregates addition on workability, me- chanical properties of castables after heated at different temperatures were researched; the microstructure of the aggregates was analyzed by SEM. The result shows that the introduction of spherical light-weight aggregates can significantly improve the flowability and reduce the water addition of the castables. Water demand of the castable is reduced from 18% with the conventional light-weight aggregates to 14% with spherical light-weight aggre- gates. In addition, light-weight castables prepared by spherical aggregates can keep the same workability with- in a wider range of water addition. Therefore, spherical aggregates are user-friendly. The introduction of spheri- cal light-weight aggregates is favorable to packing densi- ty and mechanical properties of castables, such as cold crushing strength, cold modulus of rupture, hot modulus of rupture at 1 200℃.展开更多
