Attitudes and influencing factors of nursing assistants towards hospice and palliative care nursing in chinese nursing homes: a cross-sectional study.

BACKGROUND: Hospice and palliative care nursing (HPCN) in China is mainly available at public primary care institutions, where nursing homes (NHs) are rarely involved. Nursing assistants (NAs) play an essential role in HPCN multidisciplinary teams, but little is known about their attitudes towards HPCN and related factors. METHODS: A cross-sectional study was designed to evaluate NAs' attitudes towards HPCN with an indigenised scale in Shanghai. A total of 165 formal NAs were recruited from 3 urban and 2 suburban NHs between October 2021 and January 2022. The questionnaire was composed of four parts: demographic characteristics, attitudes (20 items with four sub-concepts), knowledge (nine items), and training needs (nine items). Descriptive statistics, independent samples t-test, one-way ANOVA, Pearson's correlation, and multiple linear regression were performed to analyse NAs' attitudes, influencing factors, and their correlations. RESULTS: A total of 156 questionnaires were valid. The mean score of attitudes was 72.44 ± 9.56 (range:55-99), with a mean item score of 3.6 ± 0.5 (range:1-5). The highest score rate was "perception of the benefits for the life quality promotion" (81.23%), and the lowest score rate was "perception of the threats from the worsening conditions of advanced patients" (59.92%). NAs' attitudes towards HPCN were positively correlated with their knowledge score (r = 0.46, P < 0.01) and training needs (r = 0.33, P < 0.01). Marital status (ß = 0.185), previous training experience (ß = 0.201), location of NHs (ß = 0.193), knowledge (ß = 0.294), and training needs (ß = 0.157) for HPCN constituted significant predictors of attitudes (P < 0.05), which explained 30.8% of the overall variance. CONCLUSION: NAs' attitudes towards HPCN were moderate, but their knowledge should be improved. Targeted training is highly recommended to improve the participation of positive and enabled NAs and to promote high-quality universal coverage of HPCN in NHs.

First branchial cleft cyst accompanied by external auditory canal atresia and middle ear malformation: A case report.

BACKGROUND: We report a rare case of first branchial cleft anomaly (FBCA) accompanied by bony atresia of the external auditory canal, middle ear malformation, and location malformation of the facial nerve according to the intraoperative findings. CASE SUMMARY: A 19-year-old male patient presented to our department with a mass behind the right earlobe and recurrent postauricular swelling and pain since childhood, he also had severe hearing loss in the right ear since birth. The patient underwent surgery including mass removal, mastoidectomy, and simultaneous meatoplasty and ossiculoplasty under microscopy. No facial palsy or recurrence was noted during postoperative follow-up. CONCLUSION: FBCAs are rare, and to our knowledge, this is the first report of FBCA accompanied by external auditory canal bony atresia, middle ear malformation, and location malformation of the facial nerve. An effective postauricular approach under microscopy facilitated complete lesion removal and simultaneous otologic reconstruction.

DGCR8/miR-106 Axis Enhances Radiosensitivity of Head and Neck Squamous Cell Carcinomas by Downregulating RUNX3.

Purpose: Head and neck squamous cell carcinoma (HNSCC) is the sixth most prevalent malignant tumor worldwide, and the radiotherapy effect is strongly associated with human papillomavirus (HPV) infection. Therefore, the aim of our study was to analyze the mechanism of HPV E7 and its effects on radiosensitivity in HNSCC cells. Methods: The mRNA expression of DiGeorge syndrome critical region gene 8 (DGCR8), has-miR-106a, and Runt-related transcription factor 3 (RUNX3) was examined by quantitative real-time PCR (RT-qPCR). The protein expression of DGCR8, E7, RUNX3, caspase-3/cleaved caspase-3, poly(ADP-ribose) polymerase (PARP)/cleaved PARP, and γH2AX was measured by Western blot. The expression level of DGCR8 was measured by immunofluorescence assay. Starbase database (http://starbase.sysu.edu.cn/) was used to analyze the correlation between has-miR-106a-5p and DGCR8. TargetScan database (http://www.targetscan.org/vert_72/) was adopted to calculate the prediction of binding sites. Radiosensitivity was evaluated through clone formation assays and Cell Counting Kit-8 (CCK-8) assays. Results: In our study, we found that the mRNA and protein expression levels of HPV E7 and DGCR8 in HPV-positive HNSCC cells were higher than those in HPV-negative cells. The expression of DGCR8 was increased in FaDu and UM-SCC-4 with E7 overexpression, while the expression of DGCR8 was decreased in UM-SCC-47 and UPCI-SCC-090 with E7 silence. The miR-106a expression was increased after DGCR8 overexpression in FaDu and UM-SCC-4. However, the miR-106a expression was decreased in UM-SCC-47 and UPCI-SCC-090 with E7 silence. In radiation conditions, clone formation assays found that less clones formed in FaDu and UM-SCC-4 cells subsequent to silencing DGCR8 or miR-106a than that in the control group, and more clones were formed in UM-SCC-47 and UPCI-SCC-090 cells overexpressing DGCR8 or miR-106a than that in the control group. Luciferase reporter gene assays verified that miR-106a targeted the 3' untranslated region (UTR) of RUNX3 mRNA. MiR-106a overexpression resulted in a decrease in RUNX3 expression, and miR-106a silence increased RUNX3 expression. Rescue experiments conducted with miR-106a inhibitor restored radiation resistance and reduced DNA damage in radiation condition. Conclusions: Our study indicated that HPV E7 activated DGCR8/miR-106a/RUNX3 axis to enhance radiation sensitivity and provided directions for targeted therapeutic interventions.
