le safety in RA patients with low disease activity. The use of telemedicine has significantly increased since the outbreak of the SARS-CoV-2 pandemic. In the dermatological setting, patients with stable plaque psoriasis on maintenance therapy with biological drugs may be suitable candidates for telemedicine, although their preference for telemedicine has not yet been investigated. The aim of this study was to investigate the preference for telemedicine versus in-person visit among patients with psoriasis receiving biological drugs and the reported reasons behind their preferences. Consecutive adult patients with chronic plaque psoriasis in stable clinical remission (Psoriasis Area Severity Index [PASI] ≤ 3 for at least 12months) receiving maintenance biological therapy answered a survey investigating whether they would choose telemedicine or in-person visit for the next scheduled visit and the reasons behind their preference. The survey was undertaken through a questionnaire that was developed according to a structured process. Of the 246 participants in the survey, 118 (48%) preferred telemedicine over an in-person visit for their next scheduled visit with a dermatologist. Multivariate logistic regression analysis revealed that previous experience with digital video-communication tools was a significant predictor for the preference for telemedicine (odds ratio [OR] 10.75; 95% confidence interval [CI] 3.61-32.03), while older age (< 60years) was negatively associated with the preference for telemedicine (OR 0.30; 95% CI 0.10-0.90). The most common reasons (75%) for preferring telemedicine were saving time and safety in relation to the risk presented by the Sars-CoV-2 pandemic (38%). In contrast, 56% of the patients who preferred the in-person visit option declared that they were unable to use video-communication tools. About half of the patients with stable psoriasis receiving biological drugs may be good candidates for telemedicine.

Some scholars have found that dermal papilla spheroid-derived exosomes could promote the development of hair follicles. However, whether adipose-derived stem cell exosomes (ADSC-Exos) have a similar effect on hair growth has not been determined yet. Thus, the purpose of this article was to detect whether ADSC-Exos could promote hair regeneration. Adipose-derived stem cells (ADSCs) were isolated from 6-week-old C57BL/6 mice. Atamparib Then, ADSC-Exos were isolated from the ADSCs. Western blotting was used to detect specific exosome markers. The particle size and distribution of the exosomes were analyzed by NanoSight dynamic light scattering. A total of 12 nude mice were randomly divided into two groups (n = 6 each) the ADSC-Exos group and the control group. For the control group, a mixture of freshly isolated dermal cells (DCs) and epidermal cells (ECs) was grafted. For the ADSC-Exos group, a mixture of DCs, ECs, and 50 μg/ml of ADSC-Exos was grafted. Gross evaluation of the hair regeneration was carried out 2-3 weeks after the transplantation, and the graft site was harvested for histology at the third week. The existence of exosomes derived from ADSCs was evidenced by CD63, ALX1, and CD9 expression. Two or three weeks after the grafting, the number of regenerated hairs in the ADSC-Exos group was higher than that in the control group (p < 0.001). Histologically, the terminal hairs were remarkable in the ADSC-Exos group, whereas the hair follicles observed in the control group were comparatively immature. The ADSC-Exos group had a higher number of regenerated follicles than the control group (p < 0.001). In addition, we found that the skin tissues in the ADSC-Exos group had higher PDGF and vascular endothelial growth factor expressions and lower transforming growth factor beta 1 levels than tho
