Objective:To evaluate clinical efficacy and safety of calcium-based antimicrobial peptide compounds cooling gel (CAPCS cooling gel) in the treatment of atopic dermatitis (AD) .Methods:A randomized, double-blind, active-controlled clinical study was conducted. From July 2019 to May 2020, 80 adult patients with mild-to-moderate AD were enrolled from Beijing Friendship Hospital, Capital Medical University, and randomly and equally divided into 2 groups: test group topically treated with CAPCS cooling gel, control group topically treated with hydrocortisone cream, and the treatment was performed thrice a day for 4 consecutive weeks. Before, 1, 2 and 4 weeks after the start of treatment, efficacy was evaluated according to the Eczema Area and Severity Index (EASI), Visual Analog Scale (VAS), and Investigator′s Global Assessment (IGA) scores, and adverse events were recorded. Efficacy and safety were compared by using repeated measures analysis of variance and chi-square test.Results:Of the 80 patients with AD, 43 were males and 37 were females, and the age was 52.71 ± 16.71 years. Before the treatment, there was no significant difference in gender, age, EASI, VAS or IGA scores between the two groups (all P > 0.05). After 1- and 2-week treatment, there was no significant difference in the response rate between the test group (10.00% [4/40], 57.50% [23/40], respectively) and control group (15.00% [6/40], 52.50% [21/40] respectively, both P > 0.05). After 4-week treatment, the response rate was significantly higher in the test group (82.50%, 33/40) than in the control group (57.50%, 23/40, P < 0.05). Compared with the control group, the test group showed significantly decreased VAS scores after 1-, 2- and 4-week treatment ( U = 1253.00, 1121.00, 1091.50, respectively, all P < 0.05). No drug-related adverse events were observed in either of the groups. Conclusion:CAPCS cooling gel is safe and effective in the treatment of mild-to-moderate AD in adults, and can be applied in clinic.

Abstract Objective Monitor the use of chlorhexidine gel dressing in the central venous catheter of children and adults submitted to hematopoietic stem cell transplantation (HSCT) to check for catheter-related bloodstream infection and skin irritation while using this dressing. Methods This is a prospective observational study with 25 patients with central venous catheters (CVC) inserted for hematopoietic stem cell transplantation. Dressing characteristics, skin characteristics, clinical conditions of patients and infection-related characteristics were evaluated daily. Patients were monitored from the first day of CVC insertion until removal, up to 45 days from the CVC insertion date. Results Catheter-related bloodstream infection (CRBSI) occurred in 28% of all patients, with an association between febrile neutropenia and infection (p<0.01). Skin irritation was identified in 24% of patients. No association was found between catheter-related bloodstream infection and skin irritation (p=0.51). A significant association was observed between skin irritation and dressing removal (p=0.03). Unscheduled dressing changes corresponded to 50% of all dressing changes identified during the study, and the main reason was presence of blood in the dressing (57.8%). Conclusion Using chlorhexidine gel dressing in patients submitted to HSCT proved to be an effective measure to reduce the occurrence of catheter-related infections, when compared to literature data. The cases of CRBSI found in this study were mainly associated with the condition of neutropenia, which is very common in this population. The cases of dressing-related skin irritation and presence of blood as the main reason for unscheduled change highlight the importance of nurses having proper knowledge about how to use this dressing in order to create protocols for safe dressing use and handling.

Effects of five different dressings in the treatment of donor site:a network meta-analysis / 中国组织工程研究

BACKGROUND: At present, there is no consensus on the effect of different dressings in the healing of donor site, and few studies have directly compared the healing effect of different dressings. OBJECTIVE: To evaluate the healing effect of five different dressings on donor site wounds by network meta-analysis. METHODS: Randomized controlled trials about different dressings in the treatment of donor site wounds were retrieved by computer in PubMed, EMBASE, Cochrane, Chinese Academic Journal Full Text Database, Chinese Biomedical Literature CD-ROM Database, WanFang Data Platform and Chinese Science and Technology Journal Database. The retrieval time limit was from inception until May 2018. Literature screening, quality evaluation and data extraction were conducted independently by two postgraduates. Winbugs 1.4.3 and Stata 13.0 softwares were used for data analysis. RESULTS AND CONCLUSION: A total of 13 randomized controlled trials were included. In the observation group, foam dressing, hydrocolloid dressing, alginate dressing or silver dressing was used. In the control group, vaseline gauze was used. The results of network meta-analysis showed that the healing time of donor sites for alginate dressing, silver dressing, hydrocolloid dressing and foam dressing was significantly shorter than that of vaseline gauze (P < 0.05) , but there was no difference in wound healing time between foam dressing, hydrocolloid dressing, alginate dressing and silver dressing at the donor site (P> 0.05) . The healing effects of different dressings were ranked as follows (from good to bad) : alginate dressing, silver dressing, hydrocolloid dressing, foam dressing and vaseline gauze. Overall findings indicate that alginate dressing may be the best choice to shorten the healing time of donor site, and further investigations are warranted.

Objective. This work sought to evaluate the association between using preventive hydrocolloid dressings and the onset of pressure ulcers in hospitalized patients. Methods. Retrospective cohort study that included adult patients with high risk of pressure ulcers (PU) evaluated according to the Braden scale and who had been admitted with preventive purposes to a skin care program. The preventive care prescribed by the nursing staff included using hydrocolloid dressing plus conventional care (HD+CC) or only conventional care (CC), in a tier IV hospital in Bogotá, Colombia. Information was obtained from the clinical records of the demographic variables, health, and complications during hospitalization. Results. One-hundred seventy subjects were included in the study (23 in HD+CC and 147 in CC). In all, 30.4% of the patients in the HD+CC group and 17% in the CC group had PU during follow up (p=0.15). The ratio between the type of preventive treatment received and the development of PU obtained a raw Hazzard ratio (HR) of 1.35 (CI95%: 0.58-3.14; p=0.48) and HR adjusted for confounding variables of 1.06 (CI95%: 0.29-3.84 p=0.92). Conclusion. Our results showed no superiority of HD+CC against CC in preventing PU in adult patients with high risk according to the Braden scale. The cohort study did not reveal significant differences between both interventions. It is necessary to promote and develop clinical trials to evaluate the effectiveness of using dressings and other conventional care in high-risk patients for this type of event. (AU)
