Abstract
Objective: To explore the effects of scenario simulation teaching of junior nurses in a burns department on the fluid resuscitation care of massive burn patients during shock stage. Methods: From March 2018 to July 2019, 25 junior nurses fixed in the Department of Burn of Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine met the inclusion criteria and were recruited in this prospective before-after self-control study, including 21 females and 4 males, aged 23 to 26 years. They had a work experience of 1.0 (1.0, 2.0) years in the Department of Burn. Three teaching scenarios were made according to the three major problems in the fluid resuscitation nursing of extensive burn patients during shock stage. The teaching plans were written based on the theoretical framework of Jeffrie's nursing simulation teaching. The high feasibility and practicability of the teaching plans was verified through expert consultation and evaluation by junior nurses. According to the three scenarios in the teaching plan, the junior nurses were performed with scenario simulation teaching, with 2 hours for each scenario, 6 hours in total. In one month before and after the teaching (hereinafter referred to as before and after teaching), the comprehensive ability of junior nurses was evaluated by the teachers using the self-designed junior nurse comprehensive ability evaluation scale, and their behaviors were evaluated by themselves with Performance Self-rating Scale for Nursing Students on High Simulation Training. Data were statistically analyzed with paired sample t test. Results: After teaching, the scores on communication skills, patient admissions, condition assessments, fluid resuscitation, emergency treatment, drug management, nursing skills, instrument use, teamwork, and humanitarian care and total score in the comprehensive ability evaluation of junior nurses as evaluated by teachers were significantly higher than those before teaching (t=-8.060, -11.421, -17.232, -24.800, -4.670, -11.916, -12.131, -11.606, -14.632, -13.325, -25.068, P<0.01), with 4 items including fluid resuscitation, condition assessment, nursing skills, and equipment operation having higher scores. After teaching, the nurses' self-rating scores on communication, division of labor and cooperation, clinical decision-making, professional knowledge and skills, and professional development and critical thinking and total score were (4.6±0.4), (4.8±0.3), (4.6±0.3), (4.6±0.4), (4.6±0.4), and (23.2±1.5) points respectively, which were significantly higher than the corresponding scores of (4.1±0.7), (4.2±0.7), (3.9±0.5), (3.7±0.6), (3.9±0.5), and (18.8±2.6) points before teaching (t=-3.361, -5.721, -6.987, -7.923, -7.922, -7.367, P<0.01). Conclusions: With solving the practical problems in nursing works of fluid resuscitation care of massive burn patients during shock stage as entry point, scenario simulation teaching aims to train the clinical practice ability and adaptability of junior nurses, thereby improving junior nurses' comprehensive ability of clinical practice in the fluid resuscitation care of massive burn patients during shock stage, enhancing their self-confidence and critical thinking ability.

Abstract
Objective: To investigate the sonographic features of primary thyroid lymphoma (PTL) and to evaluate the clinical significance of ultrasound-guided core needle biopsy (US-CNB) in PTL. Methods: A total of 24 patients with suspected PTL in Sir Run Run Shaw Hospital from January 2013 to June 2018 were analyzed retrospectively. All cases were confirmed by pathology, of them 23 patients received US-CNB and 1 patient chose operation without US-CNB, including 5 males and 19 females, aged from 39 to 75 years old. The effectiveness and safety of 23 patients with US-CNB were evaluated, and the sonographic features of 20 patients with PTL diagnosed by pathology were analyzed. Descriptive statistical methods were used in the study. Results: In the 23 patients with suspected PTL underwent US-CNB, 18 patients were diagnosed as PTL, 4 patients were respectively diagnosed as subacute thyroiditis, anaplastic carcinoma, Hashimoto's thyroiditis, and fibro thyroiditis, and the another patient was hard to diagnose by US-CNB and then was diagnosed as PTL by surgical biopsy. The success rate of US-CNB for diagnosis of PTL was 18/19, and no severe complications occurred in the patients with US-CNB. The other case was diagnosed as PTL by surgical biopsy without US-CNB. Sonographic features of 20 cases with PTL (18 cases diagnosed by US-CNB and 2 cases by surgery or surgery biopsy) were as follows: (1) Most nodules had irregular shapes and unsmooth margins; (2) Hypoechoic or markedly hypoechoic nodules with honeycombed or cord structures were observed in most cases; (3) Calcification was rare; (4) Multiple lesions were common; (5) Abundant intralesional vascularization was commonly observed; (6) Most cases had intensification of posterior acoustic enhancement; (7) Thyroid gland enlargement or with irregular shape; and (8) PTL often accompanied with lymph nodes enlargement in lateral neck or central region. Conclusion: PTL has certain sonographic features, with assistance of US-CNB, more accurate diagnosis of PTL can be obtained.

Abstract
Intramuscular fat (IMF) content is a critical indicator of pork quality that affects directly the purchasing desire of consumers. However, to measure IMF content is both laborious and costly, preventing our understanding of its genetic determinants and improvement. In the present study, we constructed an accurate and fast image acquisition and analysis system, to extract and calculate the digital IMF content, the proportion of fat areas in the image (PFAI) of the longissimus muscle of 1709 animals from multiple pig populations. PFAI was highly significantly correlated with marbling scores (MS; 0.95, r2 = 0.90), and also with IMF contents chemically defined for 80 samples (0.79, r2 = 0.63; more accurate than direct analysis between IMF contents and MS). The processing time for one image is only 2.31 s. Genome-wide association analysis on PFAI for all 1709 animals identified 14 suggestive significant SNPs and 1 genome-wide significant SNP. On MS, we identified nine suggestive significant SNPs, and seven of them were also identified in PFAI. Furthermore, the significance (-log P) values of the seven common SNPs are higher in PFAI than in MS. Novel candidate genes of biological importance for IMF content were also discovered. Our imaging systems developed for prediction of digital IMF content is closer to IMF measured by Soxhlet extraction and slightly more accurate than MS. It can achieve fast and high-throughput IMF phenotype, which can be used in improvement of pork quality.

Abstract
The medial temporal lobe (MTL) is a nidus for neurodegenerative pathologies and therefore an important region in which to study polypathology. We investigated associations between neurodegenerative pathologies and the thickness of different MTL subregions measured using high-resolution post-mortem MRI. Tau, TAR DNA-binding protein 43 (TDP-43), amyloid-β and α-synuclein pathology were rated on a scale of 0 (absent)-3 (severe) in the hippocampus and entorhinal cortex (ERC) of 58 individuals with and without neurodegenerative diseases (median age 75.0 years, 60.3% male). Thickness measurements in ERC, Brodmann Area (BA) 35 and 36, parahippocampal cortex, subiculum, cornu ammonis (CA)1 and the stratum radiatum lacunosum moleculare (SRLM) were derived from 0.2 × 0.2 × 0.2 mm3 post-mortem MRI scans of excised MTL specimens from the contralateral hemisphere using a semi-automated approach. Spearman's rank correlations were performed between neurodegenerative pathologies and thickness, correcting for age, sex and hemisphere, including all four proteinopathies in the model. We found significant associations of (1) TDP-43 with thickness in all subregions (r = - 0.27 to r = - 0.46), and (2) tau with BA35 (r = - 0.31) and SRLM thickness (r = - 0.33). In amyloid-β and TDP-43 negative cases, we found strong significant associations of tau with ERC (r = - 0.40), BA35 (r = - 0.55), subiculum (r = - 0.42) and CA1 thickness (r = - 0.47). This unique dataset shows widespread MTL atrophy in relation to TDP-43 pathology and atrophy in regions affected early in Braak stageing and tau pathology. Moreover, the strong association of tau with thickness in early Braak regions in the absence of amyloid-β suggests a role of Primary Age-Related Tauopathy in neurodegeneration.

Abstract
Objective: To evaluate the effect of preventive use of etocoxib-induced preemptive analgesia on three types of pain (wound pain, swallowing pain, mouth opening pain) after extraction of impacted teeth. Methods: In this study, 60 patients (60 teeth) with impacted mandibular third molars in Department of Jinyintan Outpatient, School of Stomatology, Wuhan University from May to October 2020 were enrolled. The patients were numbered by SPSS 21.0 and randomly divided into two groups. The odd number was included in the etocoxib group, and the even number was included in the control group, with 30 cases in each group. Patients in the two groups were given etocoxib 60 mg or placebo vitamin C 100 mg 30 min before operation. Pain at 2, 4, 6, 8, 10, 12, and 24 hours after tooth extraction was recorded with numeric rating scale (NRS) score. The total dose of ibuprofen rescue intake was recorded. Kaplan-Meier curves and Log-Rank analyses were used to evaluate the proportion of patients without rescue analgesic. Results: The NRS scores of wound pain, swallowing pain and mouth opening pain in the etoricoxib group were lower than those in the control group within 24 hours after tooth extraction (P<0.05). The total dose of emergency analgesics in the etoricoxib group [(0.7±0.7) dose] was lower than that in the control group [(1.4±0.9) dose] (P<0.01). The mean time between first application of analgesics was 11.5 hours in etoricoxib group and 3.5 hours in the placebo group, respectively (P<0.05). Conclusions: This study revealed that etoricoxib has a substantial preemptive analgesic effect, resulting in the reduced use of analgesics after third molar removal.

Abstract
Background Little is known about the heterogeneous etiology of suspected non-Alzheimer’s pathophysiology (SNAP), a group of subjects with neurodegeneration in the absence of β-amyloid. Using antemortem MRI and pathological data, we investigated the etiology of SNAP and the association of neurodegenerative pathologies with structural medial temporal lobe (MTL) measures in β-amyloid-negative subjects. Methods Subjects with antemortem MRI and autopsy data were selected from ADNI (n=63) and the University of Pennsylvania (n=156). Pathological diagnoses and semi-quantitative scores of MTL tau, neuritic plaques, α-synuclein, and TDP-43 pathology and MTL structural MRI measures from antemortem T1-weighted MRI scans were obtained. β-amyloid status (A+/A−) was determined by CERAD score and neurodegeneration status (N+/N−) by hippocampal volume. Results SNAP reflects a heterogeneous group of pathological diagnoses. In ADNI, SNAP (A−N+) had significantly more neuropathological diagnoses than A+N+. In the A− group, tau pathology was associated with hippocampal, entorhinal cortex, and Brodmann area 35 volume/thickness and TDP-43 pathology with hippocampal volume. Conclusion SNAP had a heterogeneous profile with more mixed pathologies than A+N+. Moreover, a role for TDP-43 and tau pathology in driving MTL neurodegeneration in the absence of β-amyloid was supported.

Abstract
AIM To develop and evaluate an artificial intelligence triage system with high sensitivity for detecting referable diabetic retinopathy and maculopathy, while maintaining high specificity for non-referable disease, for clinical implementation within the New Zealand national diabetic retinopathy screening programme. METHODS The THEIA™ artificial intelligence system for retinopathy and maculopathy screening, was developed at Toku Eyes using routinely collected retinal screening datasets from two of the largest district health boards in Auckland, New Zealand: the Auckland District Health Board and the Counties Manukau District Health Board. All retinal images from consecutive individuals receiving retinal screening between January 2009 and December 2018 were used. Images were labelled as non-sight-threatening, potentially referable or sight-threatening for New Zealand implementation, or as referable (potentially referable + sight-threatening)/non-referable (non-sight-threatening) for global comparison. RESULTS Data from 32 354 unique people with diabetes (63 843 when including multiple visits) were available, of which 95-97%, 0.9-2.4% and 1.1-3.1% were categorized as non-sight-threatening, potentially referable and sight-threatening, respectively. Using the referable/non-referable categories, THEIA achieved overall sensitivity of 94% (95% CI 92-95) in the Auckland District Health Board and 95% (95% CI 92-97) in the Counties Manukau District Health Board datasets, while preserving specificity of 63% (95% CI 62-64) for the Auckland District Health Board and 61% (95% CI 60-62) for the Counties Manukau District Health Board. Implementing THEIA into a New Zealand national diabetic screening programme could significantly reduce the manual grading load. CONCLUSION THEIA, an artificial intelligence tool to assist in clinical decision-making, tailored to the needs of the New Zealand national diabetic screening programme, delivered high sensitivity for detecting referable retinopathy within the multi-ethnic New Zealand population with diabetes.

Abstract
The article describes our exploration of a sialendoscopy-assisted transfacial sialolithotomy approach to intraparenchymal stones in the submandibular gland with gland preservation. Five patients with large intraparenchymal stones in the submandibular gland were included. Ultrasonography and computed tomograms (CT) were performed to locate the stones. As the large stones failed to be retrieved during endoscopy, patients were treated by a transfacial lithotomy approach with sialendoscopy. The glands were preserved in all cases. This approach can be considered an optional technique for the treatment of large intraparenchymal stones in the submandibular gland that fail to be removed during a transoral procedure.

Abstract
Dedicator of cytokinesis 2 (Dock2), an atypical guanine exchange factor, is specifically expressed on immune cells and mediates cell adhesion and migration by activating Rac and regulates actin cytoskeleton remodeling. It plays a crucial role in the migration, formation of immune synapses, cell proliferation, activation of T and B lymphocytes and chemotaxis of pDCs and neutrophils. However, in-vivo physiological functions of Dock2 have been relatively seldom studied. Our previous studies showed that Dock2-/- mice were highly susceptible to colitis induced by Citrobacter rodentium infection, and in early infection, Dock2-/- mice had defects in macrophage migration. However, the specific roles of Dock2 in the migration and functions of macrophages are not clear. In this study, we found that the expression of chemokines such as chemokine (C-C motif) ligand (CCL)4 and CCL5 and chemokine receptors such as chemokine (C-C motif) receptor (CCR)4 and CCR5 in bone marrow-derived macrophages (BMDM) of Dock2-/- mice decreased after infection, which were supported by the in-vivo infection experimental results; the Transwell experiment results showed that Dock2-/- BMDM had a defect in chemotaxis. The bacterial phagocytic and bactericidal experiment results also showed that Dock2-/- BMDM had the defects of bacterial phagocytosis and killing. Furthermore, the adoptive transfer of wild-type BMDM alleviated the susceptibility of Dock2-/- mice to C. rodentium infection. Our results show that Dock2 affects migration and phagocytic and bactericidal ability of macrophages by regulating the expression of chemokines, chemokine receptors and their responses to chemokine stimulation, thus playing an essential role in the host defense against enteric bacterial infection.

Abstract
Objective: To investigate the characteristics of pulmonary function changes and its possible influencing factors in patients with pneumoconiosis. Methods: In December 2019, pneumoconiosis patients hospitalized in four departments of occupational diseases in Hunan Occupational Disease Prevention and Control Hospital from December 2015 to December 2016 were selected as subjects. Lung function including forced vital capacity (FVC) , FVC%, forced expiratory volume in one second (FEV1) , FEV1%, forced expiratory volume in one second / forced vital capacity (FEV1/FVC) , diffusion capacity of the lung foe carbon monoxide% (DLCO%) 、maximal expiratory rlow 75% (MEF75%) , maximal expiratory rlow 50% (MEF50%) and maximal expiratory rlow 25% (MEF25%) were tested, and collect their age, occupation history, smoking history and Chronic Obstructive Pulmonary Disease Self Rating Questionnaire (CAT) score. They were followed up after 3 years to analyze the 3-year decline rates of lung function indicators and their relationship with stage of pneumoconiosis, age, smoking index, baseline values of lung function and CAT score. Results: 265 cases were studied effectively. After 3 years, the values of 9 lung function indicators of pneumoconiosis patients were significantly lower than those of 3 years ago (P<0.05) . The decline rates of FEV1%, FEV1/FVC, MEF75%, MEF50% and MEF25% were positively correlated with the stage of pneumoconiosis (r=0.250, 0.290, 0.219, 0.280, 0.141, P<0.05) . The decline rates of FEV1% and MEF75% were positively correlated with smoking index (r=0.148, 0.152, P<0.05) . The decline rates of DLCO% and MEF25% were positively correlated with the baseline value of initial pulmonary function (r=0.276, 0.153, P<0.05) , while the decline rates of FEV1%, FEV1/FVC and MEF50% were negatively correlated with the baseline values of initial pulmonary function (r=-0.215, -0.146, -0.214, P<0.05) . The decline rates of FVC%, FEV1%, MEF75% and MEF50% were positively correlated with the changes of CAT scores (r=0.147, 0.208, 0.210, 0.196, P<0.05) . Logistic regression analysis showed that old age and high initial value of DLCO% were the risk factor for the decline of DLCO% (OR=1.105、1.078, P<0.05) .High smoking index was the risk factors for the decline of MEF75% (OR=1.016, P<0.05) . High stage and the increase of CAT score were the risk factors for the decline of MEF50% (OR=1.548, 1.162, P<0.05) . High initial value of MEF25% was the risk factor for the decline of MEF25% (OR=1.010, P<0.05) . Conclusion: The pulmonary function index of pneumoconiosis patients declined significantly in 3 years. The stage of pneumoconiosis, age, smoking index and degree of pulmonary function damage were related to the decline rate of pulmonary function.

Abstract
AIM To explore the applicability of diffusion-tensor imaging (DTI) sequence quantitative parameters in differentiating uterine sarcoma (USr) from degenerative uterine fibroids (DUF). MATERIALS AND METHODS Fourteen cases of USr and 30 cases of DUF were analysed retrospectively. The diffusion-weighted imaging (DWI) and DTI images were analysed by two observers using Functool software on a ADW4.6 workstation. The images were post-processed to generate an apparent diffusion coefficient (ADC) map of DWI, ADC map of DTI (ADCT map), and fractional anisotropy (FA) map. Three regions of interest (ROI) were selected from the ADC, ADCT, and FA maps to obtain the ADC, ADCT, and FA values. The receiver operating characteristic (ROC) curves of all parameters were used to analyse and compare the diagnostic value of USr and DUF. RESULTS The ADC value, ADCT value, and FA value of USr (1.190 ± 0.262 × 10-3mm2/s, 1.165 ± 0.270 × 10-9mm2/s, 0.168 ± 0.063) were significantly lower compared to the values for DUF (1.525 ± 0.314 × 10-3mm2/s, 1.650 ± 0.332 × 10-9mm2/s, 0.254 ± 0.111; all p<0.001). The diagnostic threshold values for USr were: ADC ≤1.290 × 10-3mm2/s, ADCT ≤1.322 × 10-9mm2/s and FA ≤0.192. The corresponding sensitivities and specificities were 78.6%/90%, 96.7%/92.9%, and 86.7%/85.7%, respectively. The areas under the curve (AUC) were 0.875, 0.974, and 0.831, respectively. CONCLUSIONS DTI quantitative parameters can be used to differentiate USr from DUF. The ADCT value had the highest diagnostic efficacy.

Abstract
We report a study of the anharmonic lattice dynamics in low lattice thermal conductivity (κ_{l}) material AgCrSe_{2} by many-body perturbation theory. We demonstrate surprisingly giant four-phonon scattering exclusive for the heat-carrying transverse acoustic phonons due to large quartic anharmonicity and nondispersive phonon band structure, which lead to four-phonon Fermi resonance and breaks the classical τ^{-1}∼ω^{m}T^{n} relation for phonon-phonon interactions. This strong resonant scattering extends over the Brillouin zone and substantially suppresses the thermal transport, even down to a low temperature of 100 K. The present results provide fundamental insights into the four-phonon resonant dynamics in the low-κ_{l} system with flat phonon dispersions, i.e., cuprous halides and skutterudites.

Abstract
Abstract
Background
Obstructive sleep apnea (OSA), the most common upper-airway disease, is closely associated with cardiovascular risk. However, the early detection of OSA is challenging, relying on polysomnography (PSG) or portable monitor (PM) in hospitals. A novel technology, photoplethysmography (PPG), has been developed for OSA screening. But there has been limited validation of PPG-based smart devices compared to PSG or PM.
Objective
This study aimed to investigate the feasibility and verify the validity of PPG-based smart devices in the detection of OSA in real-world settings.
Methods
A total of 119 consecutive outpatients, were recruited from the Chinese PLA General Hospital from Sep 29 to Nov 10, 2019. Participants were simultaneously tested with a smart watch, and PSG or PM for a whole night sleep.
Results
In all, 102 patients (48.5±13.7 years old, female 23.5%) were into the final analysis after excluding 17 patients with poor quality of PPG signals. Among them, 83 patients (81.3%) were diagnosed with OSA. Compared to PM, the corresponding accuracy, sensitivity and specificity of PPG-based smart device in predicting moderate to severe OSA patients ( Apnea Hypopnea Index, AHI ≥15) were 87.9% (95% Confidential Interval, CI: 78.8%–94.1%), 89.7% (95% CI: 75.8%–97.1%) and 86.0% (95% CI: 72.1%–94.7%), respectively. Compared to PSG, the accuracy, sensitivity and specificity in predicting all the sleep apnea patients (AHI ≥5) were 81.1% (95% CI: 72.1%–88.2%), 76.5% (95% CI: 50.1%–93.2%) and 100% (95% CI: 29.2%–100%), respectively. Moreover, for moderate to severe OSA patients (AHI ≥15), the predictive ability of PPG-based smart device in OSA was of no significant difference compared to PM (P=0.75) or PSG (P=0.52).
Conclusions
The PPG-based smart device demonstrated good performance in detecting OSA. Nevertheless, it requires further validation in a large-scale population on screening OSA.

Abstract
Background Randomized controlled trials (RCTs) provide the highest level of evidence and are likely to influence clinical decision-making. This study evaluated the reporting quality of RCT abstracts on drug therapy of periodontal disease and assessed the associated factors.
Material and Methods The Pubmed database was searched for periodontal RCTs published in Science Citation Indexed (SCI) dental journals from 2010/01/01 to 2019/07/17. Information was extracted from the abstracts according to a modified Consolidated Standards of Reporting Trials (CONSORT) guideline checklist. The data was analyzed using descriptive statistical analysis and the statistical associations were examined using the linear regression analysis (P <0.05).
Results This study retrieved 1715 articles and 249 of them were finally included. The average overall CONSORT score was 15.6 ± 3.4, which represented 40.9% (±0.6) of CONSORT criteria filling. The reporting rate of some items (trial design, numbers analyzed, confidence intervals, intention-to-treat analysis or per-protocol analysis, harms, registration) was less than 30%. The adequate reporting rate of some items (participants, randomization, numbers analyzed, confidence intervals, intention-to-treat analysis or per protocol analysis) was no more than 4%. None of the abstracts reported funding. According to the multivariable linear regression results, number of authors (P=0.030), word count (P <0.001), continent (P=0.003), structured format (P <0.001), type of periodontal disease (P <0.001) and international collaboration (P=0.023) have a significant association with reporting quality.
Conclusions The quality of RCT abstracts on drug therapy of periodontal disease in SCI dental journals remained suboptimal. More efforts should be made to improve RCT abstracts reporting quality. Key words:Abstracts, RCT, drug therapy, periodontal disease, CONSORT, reporting quality assessment.

Abstract
Abstract
Background: Cancer patients are regarded as highly vulnerable group in the current SARS-CoV-2/COVID-19 pandemic. Up to date, the clinical characteristics of cancer patients with COVID-19 are largely unknown.
Patients and methods: In this retrospective cohort study, we collected and analyzed data of the cancer patients with y confirmed COVID-19 infection from three designated hospitals in Wuhan, China from Jan 13, 2020, to Feb 26, 2020. Univariate and multivariate analyses were performed to assess the risk factors associated with severe events defined as a condition that admission to an intensive care unit, the use of mechanical ventilation, or death. We also followed 124 cancer patients with immune checkpoint inhibitors (ICI) and their families for their infection rate and clinical outcome.
Results: Twenty-eight COVID-19 infected cancer patients were included with median age of 65.0 years (IQR:56.0-70.0) and male gender of 60.7% (17/28). Amount of these 28 patients, 7 (25%) had lung cancer, and 8 (28.6%) were considered to be infected via hospital-associated transmission. Fifteen (53.6%) patients had severe events with the mortality rate of 28.6%. The last anti-tumor treatment within 14 days from the diagnoses of COVID significant increased risk of developing severe events (HR=4.079, 95%CI 1.086-15.322, P=0.037). The common chest CT findings were ground-glass opacity (21, 75.0%) and patchy consolidation (13, 46.3%). The patchy consolidation on CT had a higher risk for developing severe events (HR=5.438, 95%CI 1.498-19.748, P=0.010). There was only one patient (1/124, 0.8%) who have been on ICI treatment for his metastatic HCC confirmed with COVID infection, and with mild clinic presentation and a short hospital course.
Conclusions: Cancer patients showed aggressive presentation and poor outcomes with the COVID-19 infection. It is recommended that vigorous screening for COVID-19 infection should be performed for cancer patients with anti-tumor. From our limited data, there is no evidence to suggest difference in cancer patients on ICI treatment.

Abstract
Background The outbreak of Corona Virus Disease-2019 (COVID-19) has posed unprecedented pressure and threats to healthcare workers in Wuhan and the entire country. Aims To assess the effect of the COVID-19 outbreak on the sleep quality of healthcare workers in a children’s healthcare centre in Wuhan. Methods A cross-sectional, anonymized, self-reported questionnaire survey was conducted at the Children’s Healthcare Centre of Renmin Hospital, Wuhan University, Wuhan, China. The questionnaire consisted of three parts, including socio-demographic characteristics and COVID-19 epidemic-related factors, the Pittsburgh sleep quality index (PSQI), and Zung’s self-rating anxiety scale (SAS) and self-rating depression scale (SDS). Results In total, 47 out of 123 (38%) participants with PSQI scores > 7 were identified as having sleep disturbance. A logistic regression analysis showed that sleep disturbance was independently associated with being an only child (adjusted odds ratio (OR) and 95% confidence interval (CI) 3.40 (1.21–9.57), P < 0.05), exposure to COVID-19 patients (adjusted OR and 95% CI 2.97 (1.08–8.18), P < 0.05) and depression (adjusted OR and 95% CI 2.83 (1.10–7.27), P < 0.05). Conclusions We observed that, during the outbreak of COVID-19, sleep disturbance was highly prevalent among paediatric healthcare workers, and sleep disturbance was independently associated with being an only child, exposure to COVID-19 patients and depression. Therefore, more mental health services are required for front-line paediatric healthcare workers in Wuhan.
