Background::Stroke is the leading cause of mortality. This study aimed to investigate the association between stroke, comorbidities, and activity of daily living (ADL) among older adults in the United States.Methods::Participants were 1165 older adults aged 60 and older from two waves (2016 and 2018) of the Health and Retirement Study who had a stroke. Descriptive statistics were used to describe demographic information and comorbidities. Logistic regressions and multiple regression analyses were used to determine associations between stroke, comorbidities, and ADL.Results::The mean age was 75.32 ± 9.5 years, and 55.6% were female. An adjusted analysis shows that older stroke adults living with diabetes as comorbidity are significantly associated with difficulty in dressing, walking, bedding, and toileting. Moreover, depression was significantly associated with difficulty in dressing, walking, bathing, eating, and bedding. At the same time, heart conditions and hypertension as comorbidity were rarely associated with difficulty in ADL. After adjusting for age and sex, heart condition and depression are significantly associated with seeing a doctor for stroke (odds ratio [OR]: 0.66; 95% confidence interval [CI]: 0.49–0.91; p= 0.01) and stroke therapy (OR: 0.46; 95% CI: 0.25–0.84; p = 0.01). Finally, stroke problem (unstandardized β [ B] = 0.58, p = 0.017) and stroke therapy ( B = 1.42, p < 0.001) significantly predict a lower level of independence. Conclusion::This study could benefit healthcare professionals in developing further interventions to improve older stroke adults' lives, especially those with a high level of dependence.

In this study, a polyethylene glycol and dodecaldehyde modified bovine serum albumin (PEG-DSA) was developed, and its feasibility as a new high-efficiency micellar carrier for dasatinib (DAS) was explored.Circular dichroism, 1H NMR, elemental analysis, FT-IR and other methods were used to characterize the material structure and the single factor method was used to optimize the process of PEG-DSA/DAS micelles and non-PEGylated control micelles DSA/DAS.The results indicated that the optimal formulation was obtained with a mass ratio of 4∶1 between PEG-DSA and DAS, with average particle size of (37.21 ± 0.21) nm, polydispersion index (PDI) of (0.24 ± 0.04), Zeta potential of ? (15.68 ± 0.19) mV, drug loading (DL) capacity of (10.22 ± 0.34) %, and encapsulation efficiency (EE) of (42.73 ± 1.15) %. Compared with the currently reported nano-formulations of DAS, the drug loading of PEG-DSA/DAS micellar formulations was significantly increased with potential for further development.

Objective:To explore the mediating role of mindfulness in part-time nursing faculty between intrinsic motivation and work engagement.Methods:A total of 376 part-time nursing faculty were investigated with Work Preference Inventory, Five Facet Mindfulness Questionnaire-Short Form and Utrecht Work Engagement Scale. SPSS 25.0 statistical software was used to perform t test on the data. Results:The intrinsic motivation of part-time nursing faculty positively predicted work engagement ( β=0.74, P<0.001). The positive predictive effect of intrinsic motivation on job engagement was weaker than before ( β=0.55, P<0.001). Mindfulness as an intermediary variable reduced the positive predictive effect of intrinsic motivation on work engagement from 0.979 to 0.504. The indirect effect of intrinsic motivation on work engagement through mindfulness was significant (path coefficient=0.50, P<0.001), and the intermediary effect accounted for 48.51% of the total effect. Conclusion:Mindfulness plays an intermediary role between intrinsic motivation and work engagement of part-time nursing faculty. Paying attention to the mindfulness level of part-time nursing faculty plays a positive role in improving their work engagement level.

As a typical BCS Ⅱ drug, felodipine exhibits low solubility and high permeability. We herein investigated the effects of different solubilization strategies on the oral absorption of felodipine. Firstly felodipine tablets based on 200 μm, 150 μm and 25 μm particle size of bulk drug were prepared. Meanwhile, felodipine solid dispersion and felodipine nanosuspension with average particle size of (168.90 ± 6.22) nm, PDI of 0.11 ± 0.06 were prepared. The absorption rate, apparent permeability coefficient (Papp), absorption quality in duodenum, jejunum, ileum and colon of rats and in vivo pharmacokinetics of the above different felodipine preparations were investigated. The results of rat single-pass intestinal perfusion showed that the absorption of felodipine preparations in duodenum, jejunum and ileum was better than in colon. Felodipine had a wide absorption window in the small intestine, with the best absorption site in the small intestine. Papp of different felodipine preparations was greater than 2.0 × 10-5 cm/s. Thus, the low solubility was the main factor limiting the absorption. In vivo pharmacokinetic experiments demonstrated the solubilization strategies significantly improved the bioavailability. The bioavailabilities of felodipine tablets with particle sizes of 150 and 25 μm, as well as nanosuspension, and solid dispersion were 138.75%, 173.01%, 208.65% and 314.53% that of the tablets with particle size of 200 μm, respectively. Solubilization strategies can significantly improve the gastrointestinal absorption rate and absorption quality of felodipine, and thus improve its bioavailability, which provides some reference for the research on the improvement of oral absorption of BCS II drugs.

Background::Stroke is a principal cause of mortality and disability globally. Numerous studies have contributed to the knowledge base regarding self-management interventions among chronic disease patients, but there are few such studies for patients with stroke. Therefore, it is necessary to analyze self-management interventions among stroke patients. This scoping review aimed to systematically identify and describe randomized controlled trials (RCTs) of self-management interventions for adults with stroke.Methods::A review team carried out a scoping review on stroke and self-management interventions based on the methodology of Arksey and O'Malley, following the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). PubMed, Embase, Web of Science, CINAHL Plus Full Text, Medline Plus Full Text, and Cochrane Central Register of Controlled Trials were searched from inception to July 2020.Results::Fifty-four RCTs were included. The most popular study design is comparing a self-management intervention to usual care or waitlist control condition. Physical activity is the most common intervention topic, and interventions were mainly delivered face to face. The majority of interventions were located in inpatient and multiple settings. Interventions were conducted by various providers, with nurses the most common provider group. Symptom management was the most frequently reported outcome domain that improved.Conclusions::Self-management interventions benefit the symptom management of stroke patients a lot. The reasonable time for intervention is at least 6-12 months. Multifarious intervention topics, delivery formats, and providers are adopted mostly to meet the multiple needs of this population. Physical activity was the most popular topic currently. Studies comparing the effect of different types of self-management interventions are required in the future.
