Objective:To explore the level of oncology nurses’ organizational silence and its influencing factors.Methods:Totally, 278 oncology nurses were recruited to fill out the General Information Questionnaire, Nurses’ Organizational Questionnaire, Perceived Social Support Scale and Connor-Davidson Resilience Scale short version.Results:The score of Nurses’ Organizational Questionnaire was (51.27±17.28), the score of acquiescent silence was (15.91±5.42), the score of defensive silence was (15.83±6.29), the score of prosocial silence was (11.03±4.16) and the score of indifferent silence was (8.50±3.46). The perceived social support and psychological reliance were negatively associated with nurses’ organizational silence ( r values were -0.364, -0.497, all P<0.01). The results of multiple linear regression analysis showed that age, degree of education, perceived social support and psychological reliance were the influencing factors of oncology nurses’ organizational silence (all P<0.05), which could explain 45.00% of the variation. Conclusions:The level of oncology nurses’ organizational silence is at a medium level, which should be improved. Nursing managers should pay attention to the phenomenon of oncology nurses’ organizational silence, and take appropriate interventions to break the phenomenon, so as to improve the job satisfaction and work efficiency of nurses’.

BACKGROUND: Rapid on-site evaluation (ROSE) is a technique used for simultaneous evaluation of biopsy specimens through rapid cytology staining. Diff-Quik (DQ) staining is the most commonly employed method for cytological rapid on-site evaluation (C-ROSE). However, the utilization of DQ staining for on-site cytological interpretation remains uncommon among pathologists in China, posing challenges to the implementation of C-ROSE. This study aims to assess the application of rapid hematoxylin-eosin (HE) staining and DQ staining for C-ROSE during percutaneous needle biopsy of peripheral lung cancer and evaluate the value of rapid HE staining in C-ROSE. METHODS: Computed tomography (CT)-guided lung biopsies were conducted on 300 patients diagnosed with peripheral lung cancer. The patients were randomly assigned to two groups for C-ROSE using either rapid HE staining or DQ staining, and subsequently the two methods were compared and evaluated. RESULTS: The concordance rate between C-ROSE and histopathological diagnosis was 96.7%. The median staining time for rapid HE staining was 160 s, while that for DQ staining was 120 s, representing a significant difference between the two groups (P<0.001). However, there were no significant differences observed in terms of total biopsy time, concordance rate with histopathology, cytology specimen peeling rate, and incidence of serious adverse reactions between the two groups (P>0.05). CONCLUSIONS Both staining methods comply with C-ROSE criteria in the biopsy setting of peripheral lung cancer. Rapid HE staining is more aligned with domestic clinical requirements and holds potential for further promotion and adoption in C-ROSE.

Objective To evaluate the value of chromosomal microarray analysis (CMA) for genetic evaluation of fetal ultrasound abnormality. Methods A total of 180 pregnant women with fetal abnormality detected by prenatal ultrasound diagnosis in the first trimester during the period from January 2020 through May 2022 were enrolled as the study subjects. All prenatal fetal screening samples were subjected to G-band karyotyping and CMA. Results G-band karyotyping detected normal karyotypes in 168 samples (93.85%) and abnormal karyotypes in 11 samples (6.15%), and CMA detected 17 positive samples (9.44%) and 163 negative samples (90.56%). The seventeen positive samples included 11 pathogenic copy number variations (CNVs) and 6 variants of unknown significance (VOUS), and there were 11 CMA-positive results consistent with G-band karyotyping, and 6 additional pathogenic CNVs mainly included microdeletion and microduplication syndromes. The detection rates of pathogenic CNVs were 11.11%, 2.63%, 2.78%, 4.00%, 0, 0, 11.11% and 0 among the fetuses with abnormal structure of the cardiovascular system, the lymphatic system, the nervous system, the digestive system, the cranial and face system, the skeletal system, the urinary system, and other system (χ² =8.188, P = 0.316). All eleven fetuses with pathogenic CNVs detected by CMA were all induced for abortion. Conclusion CMA improves the detection of genetic abnormality among fetuses with ultrasound abnormality in relative to G-band karyotyping, which is feasible for prenatal cytogenetic diagnosis among fetuses with ultrasound abnormality

Objective:To assess the clinical effectiveness and safety of Omalizumab for treating pediatric allergic asthma in real world in China.Methods:The clinical data of children aged 6 to 11 years with allergic asthma who received Omalizumab treatment in 17 hospitals in China between July 6, 2018 and September 30, 2020 were retrospectively analyzed.Such information as the demographic characteristics, allergic history, family history, total immunoglobulin E (IgE) levels, specific IgE levels, skin prick test, exhaled nitric oxide (FeNO) levels, eosinophil (EOS) counts, and comorbidities at baseline were collected.Descriptive analysis of the Omalizumab treatment mode was made, and the difference in the first dose, injection frequency and course of treatment between the Omalizumab treatment mode and the mode recommended in the instruction was investigated.Global Evaluation of Treatment Effectiveness (GETE) analysis was made after Omalizumab treatment.The moderate-to-severe asthma exacerbation rate, inhaled corticosteroid (ICS) dose, lung functions were compared before and after Omalizumab treatment.Changes in the Childhood Asthma Control Test (C-ACT) and Pediatric Asthma Quality of Life Questionnaire (PAQLQ) results from baseline to 4, 8, 12, 16, 24, and 52 weeks after Omalizumab treatment were studied.The commodity improvement was assessed.The adverse event (AE) and serious adverse event (SAE) were analyzed for the evaluation of Omalizumab treatment safety.The difference in the annual rate of moderate-to-severe asthma exacerbation and ICS reduction was investigated by using t test.The significance level was set to 0.05.Other parameters were all subject to descriptive analysis.A total of 200 allergic asthma patients were enrolled, including 75.5% ( n=151) males and 24.5% ( n=49) females.The patients aged (8.20±1.81) years. Results:The median total IgE level of the 200 patients was 513.5 (24.4-11 600.0) IU/mL.Their median treatment time with Omalizumab was 112 (1-666) days.Their first dose of Omalizumab was 300 (150-600) mg.Of the 200 cases, 114 cases (57.0%) followed the first Omalizumab dosage recommended in the instruction.After 4-6 months of Omalizumab treatment, 88.5% of the patients enrolled ( n=117) responded to Omalizumab.After 4 weeks of treatment with Omalizumab, asthma was well-controlled, with an increased C-ACT score [from (22.70±3.70) points to (18.90±3.74) points at baseline]. Four-six months after Omalizumab administration, the annual rate of moderate-to-severe asthma exacerbation had a reduction of (2.00±5.68) per patient year( t=4.702 5, P<0.001), the median ICS daily dose was lowered [0 (0-240) μg vs. 160 (50-4 000) μg at baseline] ( P<0.001), the PAQLQ score was improved [(154.90±8.57) points vs. (122.80±27.15) points at baseline], and the forced expiratory volume in one second % predicted (FEV 1%pred) was increased [(92.80±10.50)% vs. (89.70±18.17)% at baseline]. In patients with available evaluations for comorbidities, including allergic rhinitis, atopic dermatitis or eczema, urticaria, allergic conjunctivitis and sinusitis, 92.8%-100.0% showed improved symptoms.A total of 124 AE were reported in 58 (29.0%) of the 200 patients, and the annual incidence was 0(0-15.1) per patient year.In 53 patients who suffered AE, 44 patients (83.0%) and 9 patients (17.0%) reported mild and moderate AE, respectively.No severe AE were observed in patients.The annual incidence of SAE was 0(0-1.9) per patient year.Most common drug-related AE were abdominal pain (2 patients, 1.0%) and fever (2 patients, 1.0%). No patient withdrew Omalizumab due to AE. Conclusions:Omalizumab shows good effectiveness and safety for the treatment of asthma in children.It can reduce the moderate-to-severe asthma exacerbation rate, reduce the ICS dose, improve asthma control levels, and improve lung functions and quality of life of patients.
