ABSTRACT
Chronic obstructive pulmonary disease (COPD) can be prevented and treated through effective care, reducing exacerbations and hospitalizations. Early identification of individuals at high risk of COPD exacerbation is an opportunity for preventive measures. However, many patients struggle to follow their treatment plans because of a lack of knowledge about the disease, limited access to resources, and insufficient clinical support. The growth of digital health-which encompasses advancements in health information technology, artificial intelligence, telehealth, the Internet of Things, mobile health, wearable technology, and digital therapeutics-offers opportunities for improving the early diagnosis and management of COPD. This study reviewed the field of digital health in terms of COPD. The findings showed that despite significant advances in digital health, there are still obstacles impeding its effectiveness. Finally, we highlighted some of the major challenges and possibilities for developing and integrating digital health in COPD management.
ABSTRACT
PURPOSE: To evaluate the three symptom indicators of scalp seborrheic dermatitis (SSD), namely scalp flaking, maximum erythema area, and pruritus, to develop a "16-point scale," to explore its relationship with the severity of SSD, and verify the reliability of the 16-point scale. METHOD: A dermatologist evaluated patients with SSD using a 16-point scale, and statistically analyzed the collected data with the help of SPSS 26.0 software. The measurement data are expressed as (mean ± SD), and the intergroup comparison was done using a non-parametric test. We performed the correlation analysis using the bivariate correlation analysis method, and the relationship among non-normal distribution data variables were analyzed using Spearman's correlation coefficient. p < 0.05 indicated that the difference was statistically significant. RESULTS: The total score of the "16-point scale" strongly correlated with the severity of disease, where scalp flaking had the strongest correlation. As compared with a single score, the correlation of the total score with the severity of disease was higher. The scoring range for mild patients was (0, 5], that for moderate patients was (5, 9], and that for severe patients was (9, 16]. CONCLUSION: A "16-point scale", consisting of items for adherent scalp flaking (0-10), maximum erythema area (0-3), and pruritus (0-3), was used to score the patients with SSD, and the total score was strongly correlated with and differentiated the severity of SSD. Recommended evaluation criteria: a total score of 0-5 points indicates mild SSD, 6-9 points indicates moderate SSD, 10-16 points indicates severe SSD. These criteria can help to standardize disease diagnosis and treatment, and efficacy assessment.
ABSTRACT
OBJECTIVE: To evaluate the clinical efficacy of a combination treatment of traditional Chinese medicine (TCM) in scalp seborrheic dermatitis (SSD) of differing severity. METHODS: Our study included patients with typical SSD who visited the Medical Research Center for Hair and Skin at our hospital. Symptoms were evaluated using a "16-point scale" developed at the center. Patients who had mild SSD were treated with Pi Fu Kang Xi Ye (PFKXY), those with moderate SSD were treated with PFKXY combined with Run Zao Zhi Yang Jiao Nang (RZZYJN), and those with severe dermatitis were treated with PFKXY and RZZYJN along with garlicin enteric-coated tablets. Patients were asked to revisit 4 weeks later to evaluate the efficacy. RESULTS: Symptom scores of all patients decreased by (5.48 ± 2.51) after treatment as compared with before treatment, and the results of t-test and correlation test were significant (p < 0.01). The scores of patients with mild, moderate and severe SSD decreased by 3.14 ± 1.83, 4.90 ± 1.77, and 8.05 ± 2.21, respectively, after treatment as compared with before treatment. Among them, the changes in scores of patients with moderate dermatitis before and after treatment were significant in the t-test and correlation test (p < 0.01). CONCLUSION: In this study, the combination treatment of TCM showed significant efficacy in the treatment of mild, moderate, and severe SSD, and the efficacy was stable, especially for patients with moderate SSD.
ABSTRACT
Polymeric nanoparticles for drug delivery are attracting broad interest along with the rapid development of biomedical and healthcare research. Here, we prepared a series of nanocapsules via electrostatic precipitation of chitosan and lecithin micelles. These nanocapsules have controlled diameters (â¼25-200 nm) that only slightly changed after several lyophilization-dissolving cycles, suggesting their excellent stability for long-term storage. In cell experiments, these nanocapsules obviously reduced the cytotoxicity of encapsulated small molecules, and clearly showed size-dependent endocytosis. In a dynamic release model mimicking the in vivo circulatory system, the nanocapsules demonstrated superiority over micelles as drug carriers due to their stable structures. To the best of our knowledge, this is the first dynamic model used to evaluate the drug-release behaviour, which might provide a new way to study the release profile of other potential drug carriers.
