Posttraumatic stress symptoms in Chinese children with ongoing cancer treatment and their parents: Are they elevated relative to healthy comparisons?

OBJECTIVE: The objective of this work is to compare posttraumatic stress symptoms (PTSS) between families of children on cancer treatment and families of healthy children in China and to analyse the association among child PTSS, parent PTSS, and depression in the cancer group. METHODS: Participants were children on cancer treatment (n = 91) and their parents (n = 91), and healthy children (n = 114) and their parents (n = 96). The children were asked to self-report PTSS, and the parents completed self-reported measures of PTSS and depression. RESULTS: Although the prevalence of probable PTSD in children on cancer treatment was higher than that in comparisons (8.79% vs. 0.88%, P < 0.01), no statistic differences in PTSS levels were found between the two groups (P > 0.05). However, significant differences in PTSS levels and the prevalence of severe PTSS (21.98% vs. 1.04%) between parents of children with cancer and comparisons were observed (P < 0.001). Parent PTSS and depression were positively associated with child PTSS in the cancer group (P < 0.01). CONCLUSION: The prevalence of probable PTSD in Chinese children with cancer was low, but PTSS was remarkably prevalent in their parents. Greater parent PTSS and depression were related to greater child PTSS. Results underline the importance to provide supportive psychological care for Chinese parents of children undergoing cancer treatment.

Investigating the Efficacy of Hydrocolloid Dressing for Preventing Nasotracheal Tube-Related Pressure Injury in the PICU.

OBJECTIVES: To investigate the efficacy of hydrocolloid dressing in reducing the occurrence rate and severity of nasotracheal tube-related pressure injury. DESIGN: Randomized controlled trial. SETTING: A PICU in a tertiary medical center in southern China. PATIENTS: Pediatric patients received invasive mechanical ventilation via nasotracheal tubes. INTERVENTIONS: The hydrocolloid dressing was cut into an optimal square size, which should cover the area from the nasal columella to the ala. MEASUREMENTS AND MAIN RESULTS: Eligible participants were randomly allocated to the control group and the experimental group. The participants in the experimental group received hydrocolloid dressing to protect nasal skin from the beginning of nasotracheal intubation, while the participants in the control group received the current care procedure (without hydrocolloid dressing) unless pressure injuries occurred. The hydrocolloid dressing was changed daily to assess the nasal skin. The pressure injury staging system that was redefined and updated by the National Pressure Ulcer Advisory Panel in 2016 was used. The mean duration of nasotracheal intubation was 150.10 ± 117.09 hours in the experimental group and 161.75 ± 120.72 hours in the control group. Forty-five participants had nasotracheal tube-related pressure injuries in control group, whereas 26 patients had in experimental group (72.6% vs 43.3%; absolute difference, 29.3%, 95% CI, 12.5-46%; p = 0.001). The median survival times of the nasal skin integrity were 95.5 hours in the control group and 219.5 hours in the experimental group (p < 0.001). CONCLUSIONS: Hydrocolloid dressing can not only reduce the occurrence rate of nasotracheal tube-related pressure injury in the child with long-term nasotracheal intubation but also improve the endurance of the nasal skin significantly.

Internet-Based Self-Help Mindful Self-Compassion Intervention for Parents of Children With Cancer: A Pilot Study.

BACKGROUND: Parents of children with cancer may experience persistent psychological distress and impaired physical health throughout their children's diagnosis and treatment. OBJECTIVE: This study aimed to develop a mindful self-compassion program for parents of children with cancer and explore its effect. METHODS: This pre-post-test study without a control group was conducted with 34 Chinese parents of children with cancer, using mixed methods. Participants received a 6-week internet-based self-help mindful self-compassion intervention. Self-compassion, post-traumatic stress symptoms, depression, and sleep quality were measured at baseline and at 10 weeks post-baseline. Semi-structured interviews were conducted with 9 completers within 10 days after the intervention was completed. RESULTS: Significant differences were observed in self-compassion, re-experiencing, physical depressive symptoms, and sleep quality. Two participants reported feeling miserable or recalling distressing experiences, of which one withdrew from the study while the other completed the intervention. CONCLUSION: The program could improve self-compassion, re-experiencing, physical depressive symptoms, and sleep quality in parents of children with cancer, which demonstrated the feasibility of delivering a self-help mindful self-compassion intervention through the internet. Increasing retention rates in future studies merits further discussion.

MiR-124-3p helps to protect against acute respiratory distress syndrome by targeting p65.

BACKGROUND: Acute respiratory distress syndrome (ARDS) is a severe form of acute lung injury that has a high mortality rate and leads to substantial healthcare costs. MicroRNA-124-3p (miR-124-3p) helps to suppress inflammation during a pulmonary injury. However, its mechanism of action is largely unknown, and its role in ARDS remains to be determined. METHODS: Mice and NR8383 cells were exposed to lipopolysaccharides (LPS) to induce ARDS, and their miR-124-3p levels were determined. After a miRNA agomir was administrated to the mice, their pulmonary injuries were evaluated by H&E staining and assays for peripheral inflammatory cytokine levels. The direct interaction between miR-124-3p and p65 was predicted, and then confirmed by a luciferase activity assay. The role played by miRNA-124-3p in regulating p65 expression was further examined by transfection with its agomir, and its role in cell apoptosis was investigated by observing the effects of miRNA overexpression in vitro and in vivo. RESULTS: After exposure to LPS, there was a consistent decrease in miR-124-3p expression in the lungs of mice and in NR8383 cells. After treatment with the miR-124-3p agomir, the degrees of pulmonary injury (e.g. alveolar hemorrhage and interstitial edema), and the increases in IL-1ß, IL-6, and TNF-α levels induced by LPS were significantly attenuated. Overexpression of miR-124-3p in NC8383 cells and lung tissues significantly suppressed LPS-induced p65 expression and cell apoptosis. CONCLUSIONS: These results suggest that miR-124-3p directly targeted p65, and thereby decreased the levels of inflammation and pulmonary injury in a mouse model of ARDS.
