ABSTRACT

Objective: To investigate the clinical value of observing perioperative changes of myeloperoxidase (MPO) and neutrophil elastase (NE) in coronary artery circulation in patients underwent valve replacement surgery. Methods: This perspective cohort study was performed in patients who underwent valvular surgery in Nanjing Drum Tower Hospital and Fuwai Hospital from June 2021 to June 2022. Patients were divided into perioperative myocardial injury group and age-, sex- and type of cardiac procedure-matched non-perioperative myocardial injury control group in the ratio of 1∶1. Perioperative myocardial injury was defined as cardiac troponin T (cTnT)>0.8 μg/L on the first postoperative day (POD), and the cTnT level on the second POD increased by more than 10% compared with the cTnT level on the first POD. During the operation, blood samples were collected from the coronary sinus before clamping ascending aorta, and within 5 minutes after de-clamping ascending aorta. Then, the levels of MPO and NE on coronary sinus were continuously measured. The death, severe ventricular arrhythmia, pneumonia, re-intubation, repeat cardiac surgery, extracorporeal membrane oxygenation (ECMO), intra-aortic balloon pump (IABP), continuous renal replacement therapy (CRRT), mechanical ventilation time and the duration of intensive care unit (ICU) were recorded. The levels of MPO and NE and the incidence of clinical outcomes were compared between the myocardial injury group and the control group. The independent risk factors of myocardial injury were analyzed by multivariate logistic regression. Results: A total of 130 patients were enrolled, aged (60.6±7.6) years old, with 59 males (45.4%). There were 65 patients in the myocardial injury group and 65 patients in the control group. During hospitalization, there was no death, ECMO, IABP and CRRT cases in both groups. Compared with the control group, the incidence of severe ventricular arrhythmia (13.8%(9/65) vs. 3.1%(2/65), P=0.03), pneumonia (20.0%(13/65) vs. 3.1%(2/65), P=0.03), re-intubation (6.2%(4/65) vs. 0, P=0.04) was significantly higher in myocardial injury group. The mechanical ventilation time (16.8(10.7, 101.7) h vs. 7.5(4.7, 15.1) h, P<0.01), and the duration of ICU (3.7(2.7, 18.9) vs. 2.7(1.8, 6.9)d, P<0.01) were significantly longer in myocardial injury group compared with the control group. There was no significant difference in the levels of MPO and NE in coronary sinus blood between the two groups before aortic clamping (all P>0.05). However, MPO ((551.3±124.2) μg/L vs. (447.2±135.9) μg/L, P<0.01) and NE ((417.0±83.1)μg/L vs. (341.0±68.3)μg/L, P<0.01) after 5 min aortic de-clamping were significantly higher in myocardial injury group than in the control group. Multivariate logistic regression analysis showed that the levels of NE (OR=1.02, 95%CI: 1.01-1.02, P<0.01), MPO (OR=1.00, 95%CI: 1.00-1.01, P=0.02) and mechanical ventilation time (OR=1.03, 95%CI: 1.01-1.06, P=0.02) were independent risk factors of myocardial injury in patients after surgical valvular replacement. Conclusion: Perioperative myocardial injury is related poor clinical outcomes, perioperative NE and MPO in coronary artery circulation are independent risk factors of perioperative myocardial injury in patients undergoing valve replacement surgery.

ABSTRACT

Objective:To investigate the current situation of radiotherapy resources in medical institutions at all levels in Jiangsu province.Methods:The survey was initiated with the subproject " Medical Radiation Protection Monitoring" of the National Key Occupational Disease Monitoring Project. Unified electronic questionnaires were designed based on the survey content, distributed and recycled through the network, to investigate all medical institutions (excluding military hospitals) conducting radiotherapy in Jiangsu province in 2020.Results:By the end of 2020, there were 113 medical institutions (excluding military hospitals) carrying out radiotherapy in Jiangsu Province, including 86 hospitals Level Ⅲ, 23 hospitals Level Ⅱ, 2 hospitals Level I, and 2 unrated hospitals, with the largest number of hospitals in northern Jiangsu. A total of 2 033 workers were engaged in radiotherapy, with inclusion of 319 medical physicists, accounting for 15.69% of the total, slightly higher than the national average. There were 195 sets of radiotherapy equipment, including 153 medical linear accelerators and 31 afterloading units, 9 Gamma Knife and 2 60Co therapeutic machines, respectively. The number of accelerators per million population was 1.80, more than nationwide average, 1.45, in 2018. The annual number of patients treated with radiotherapy was 92 441, with an annual treatment frequency of 1.090 per 1 000 population, lower than international health-care level I. Conclusions:Radiotherapy resources in Jiangsu province exceed the national average, but may not fully meet the medical requirements of existing patients, and there is still a significant gap from international health-care level I.

ABSTRACT

AIM: To investigate the role of visual perception training on the recovery of visual function at all levels and the improvement of perceptual eye position in children with intermittent exotropia(IXT).METHODS: Prospective clinical study. A total of 74 patients with IXT who received corrective surgery for strabismus in the Ophthalmology Department of the First People's Hospital of Lanzhou City from January to June 2022 were collected and followed up for 3mo. The patients were randomly divided into 2 groups at 1d after surgery: 35 patients in the training group received binocular visual perception training, and 39 patients in the control group did not receive visual training. The changes of visual function and perceived eye position at all levels were observed at 1d and 3mo after operation.RESULTS: There were 24 patients(69%)with simultaneous perception in the training group at 1d after surgery and 34 patients(97%)with recovered visual function at 3mo after surgery, which was significantly higher than 1d after surgery(P=0.002). Furthermore, there were 22 cases(56%)of fusion function in the control group at 3mo after surgery, 13 cases(33%)of far stereopsis, 20 cases(51%)of dynamic stereopsis and 17 cases(44%)of static fine stereopsis. In the training group, there were 31 cases(89%)of fusion function, 25 cases(71%)of far stereopsis, 30 cases(86%)of dynamic stereopsis and 27 cases(77%)of static fine stereopsis, which were significantly higher than those in the control group(all P&#x003C;0.05). The degree of perceived eye displacement in the training group decreased more significantly than that in the control group(all P&#x003C;0.05).CONCLUSION: Postoperative visual perceptual training in children with IXT can promote recovery of visual function at all levels, improve perceptual eye position and enhance the control of eye position at the perceptual level of the brain.

ABSTRACT

Background Healthcare workers suffer from great internal and external pressure and are prone to burnout. Existing studies have shown that depressive symptoms are important influencing factors of burnout, both of which are closely related to job stress. Objective To analyze overall prevalence of burnout among healthcare workers using a new survey tool developed by our team, and to reveal potential influencing factors related to burnout. Methods A cross-sectional multi-center study was conducted in August–October 2019 and June–September 2020, using multi-stage stratified cluster sampling. A total of 8738 healthcare workers from 22 hospitals in 5 provinces (Shandong, Hubei, Hunan, Guangdong, and Chongqing) of China were selected in this study. A set of survey questionnaires, including the general information questionnaire and the Chinese versions of General Burnout Scale, Core Occupational Stress Scale, Patient Health Questionnaire-9, and Self-administered Sleep Questionnaire were distributed. Independent samples t-test or one-way ANOVA were employed for inter-group comparison of burnout. Spearman correlation was used to evaluate correlations among burnout, depressive symptoms, and occupational stress. Stepwise linear regression was conducted to identify factors independently associated with burnout. Process plug-in was used to test potential mediating effect of depressive symptoms on occupational stress and burnout. Results Of the 8738 questionnaires distributed, 8456 valid questionnaires were collected, and the recovery rate was 96.77%. Among the 8456 healthcare workers, the prevalence of burnout was 58.0%, that of occupational stress was 31.8%, and that of depressive symptoms was 31.0%. Among those with depressive symptoms and occupational stress, the proportions of burnout were 86.7% and 83.7%, respectively. According to the stepwise linear regression analysis, depressive symptoms, occupational stress, work experience, drinking, and marital status were all independent influencing factors of burnout. Especially, depressive symptoms, social support, and organization and reward had significant influences on burnout (b'=0.455, −0.183, 0.220, P<0.001). Depressive symptoms showed mediating effects on occupational stress (and its subscales) and burnout, and the contribution rates of the mediating effects were 41.00%, 47.02%, 43.44%, 56.62%, and 59.45%, respectively. Conclusion Burnout is a prominent problem among healthcare workers in the 5 provinces, with the prevalence of 58.0%. And nearly 1/3 suffering from depressive symptoms and occupational stress, which has a great impact on burnout.

ABSTRACT

Background Manufacturing industry is the main body of China's national economy, and manufacturing employees provide solid guarantee and support for the vigorous development of China's manufacturing industry. The research on job burnout of manufacturing employees is helpful to prevent or alleviate the health damage and economic loss caused by job burnout. Objective To investigate the status and influencing factors of job burnout among manufacturing employees in China, and evaluate the potential mediating effect of job burnout between job stress and depressive symptoms. Methods A cross-sectional study was performed from August to October 2019 and from June to September 2020 in seven provinces of China. Study participants were recruited from 21 manufacturing companies covering 11 manufacturing subdivisions using multistage stratified cluster sampling. General Burnout Scale, Core Occupational Stress Scale, and Patient Health Questionnaire-9 were used to evaluate job burnout, job stress, and depressive symptoms. Mann-Whitney U test and Kruskal-Wallis H test were used to compare data between two independent samples and multiple independent samples of measurement data; Pearson χ2 test was used to compare the rate of enumeration data; Spearman rank correlation analysis was used to evaluate correlation between selected variables; binary logistic regression was used for multivariate analysis; stepwise regression and bias-corrected Bootstrap method were used to test potential mediating effect. Results A total of 10973 valid questionnaires were collected. The M (P25, P75) scores of exhaustions, cynicism, professional efficacy, job burnout, job stress, and depressive symptoms were 1.6 (0.4, 3.0), 1.0 (0.2, 2.2), 4.8 (3.2, 5.7), 1.6 (0.8, 2.5), 45.0 (40.0, 50.0), and 7.0 (4.0, 11.0), respectively. The positive rates of job burnout, job stress, and depressive symptoms were 53.4% (5865/10973), 28.4% (3116/10973), and 29.4% (3231/10973), respectively. The influencing factors of job burnout were gender (versus male; OR for female=0.852), age (versus≤25 years old; ORs for 26-30, 31-40, 41-50, 51-60 years old=0.824, 0.819, 0.738, 0.677), education level (versus junior high school or below; ORs for senior high school/technical secondary school, junior college/vocational college, graduate school or above=1.119, 1.345, 1.331), income per month (versus<3000 yuan; ORs for 3000-4999, 5000-6999, 7000-8999, 9000-10999, ≥11000 yuan=0.513, 0.470, 0.430, 0.375, 0.411), position (versus assembly line; OR for non-assembly line=0.814), average weekly working hours (versus ≤40 h; ORs for 61-70, >70 h=1.199, 1.519), and drinking (versus non-drinking; OR for drinking=1.261). Job burnout was positively correlated with job stress and depressive symptoms (r=0.556, 0.508, P<0.001). Job burnout played a partial mediating role between job stress and depressive symptoms, and its contribution value accounted for 63.2% of the total effect. Conclusion Manufacturing industry employees' job burnout problem is prominent in China, and there are many factors affecting job burnout. Job burnout may play a partial mediating role between job stress and depressive symptoms in the target group.

ABSTRACT

Background With the rise and deepening of positive psychology research, theoretical research on job burnout is also deepening worldwide, and some new theoretical models are proposed, such as the burnout-engagement continuum, but there is still a lack of empirical research and application in China. Objective To analyze the current situation and influencing factors of five profiles in the burnout-engagement continuum in working populations of China: job engagement, ineffective, overextended, disengaged, and burnout. Methods From August to October 2019 and June to September 2020, a total of 27344 subjects of key occupations in six typical industries, including teachers, firefighters, manufacturing workers, medical staff, flight attendants, and traffic police, were selected from 10 provinces (cities) in the eastern, middle, and western regions of China by multistage stratified cluster sampling method for cross-sectional investigation. Maslach Burnout Inventory-General Survey and Core Occupational Stress Scale were used to evaluate job burnout and occupational stress respectively. χ2 test was used to compare rates of count data. Binary logistic regression was used for multivariate analysis of the five profiles. Results Among the subjects, 24.4%, 61.9%, 31.9%, 12.7%, and 11.8% were the prevalence rates of job engagement, ineffective, overextended, disengaged, and burnout, respectively. Flight attendants (35.7%), firefighters (29.0%), traffic police (28.5%), and manufacturing workers (26.5%) had high prevalence rates of job engagement profile. Medical stuff (62.9%) and manufacturing workers (61.8%) had high prevalence rates of ineffective profile. Teachers (39.2%), traffic police (37.2%), and medical stuff (35.5%) had high prevalence rates of overextended profile. Traffic police (17.9%), medical staff (14.3%), and teachers (13.4%) had high prevalence rates of disengaged profile. Traffic police (16.9%), medical staff (13.4%), and teachers (13.3%) had high prevalence rates of burnout profile. The results of multivariate analysis showed that gender, age, education level, marital status, weekly working hours, length of service, income per month, shift work, smoking, drinking, industry, and occupational stress entered into the regression equations of job engagement, ineffective, overextended, disengaged, and burnout. The risks of overextended (OR=1.456-2.970), disengaged (OR=1.306-4.092), and burnout (OR=1.302-4.102) among the high rating groups of the four factors of occupational stress were higher than those among the low rating groups. Flight attendants (OR=0.296) and firefighters (OR=0.329) had lower risks of burnout than teachers, and flight attendants (OR=0.392) and firefighters (OR=0.466) had lower risks of disengaged than teachers. Conclusion Among the prevalence rates of the five profiles in the burnout-engagement continuum in the 6 typical occupational populations in China, ineffective profile is the highest, followed by overextended, and burnout is the lowest. Gender, age, education level, marital status, weekly working hours, length of service, income per month, shift work, smoking, drinking, industry, and occupational stress have different effects on the five profiles, but industry and occupational stress have greater impacts on job burnout.

ABSTRACT

Background As one of the common tools for job burnout assessment, Maslach Burnout Inventory-General Survey (MBI-GS), its reliability and validity across different populations in China have not been examined yet. Objective To evaluate the reliability and validity of General Burnout Scale (GBS) by multiple occupational groups through the translation and preliminary test of MBI-GS. Methods Based on the Special Project of Occupational Hazards in Key Populations led by the Institute of Occupational Health and Poison Control, China CDC, key occupational groups in five typical industries were selected by multi-stage stratified cluster sampling, including teachers, firefighters, manufacturing workers, medical staff, and traffic police. Confirmatory factor analysis (CFA) was used to evaluate the construct validity of GBS by single-factor, two-factor, and three-factor structure models. The model fitness was assessed by ratio of the chi-square statistic to the respective degrees of freedom (χ2/ν), root mean square error of approximation (RMSEA), goodness-of-fit index (GFI), comparative fit index (CFI), and parsimony-adjusted non-normed fit index (PNFI). Spearman correlation analysis was used to calculate the criterion validity of GBS with occupational stress, depressive symptoms, and sleep disorders. Cronbach's α coefficient and composite reliability (CR) coefficient were used to evaluate the internal consistency reliability of GBS. Results A total of 3485 subjects were surveyed in this study, 3375 valid questionnaires were recovered with a valid response rate of 96.84%. The results of CFA showed that in the adjusted three-factor structure model of GBS (exhaustion, cynicism, and professional efficacy), the χ2/ν < 4, the RMSEA ranged from 0.032 to 0.069, the GFI > 0.90, the CFI > 0.90, and the PNFI > 0.70, which illustrated a good fitness than that of the single- or the two-factor structure models in different occupational groups. The Spearman correlation analysis results showed that occupational stress, depressive symptoms, and sleep disorders were positively correlated with exhaustion and cynicism dimensions, and negatively correlated with professional efficacy dimension of the GBS, with the \begin{document}$ \left| r \right| $\end{document} ranging from 0.139 to 0.662 (P<0.05) in overall subjects. For traffic police and firefighters, professional efficacy was not correlated with depressive symptoms or sleep disorders (P>0.05). The Cronbach's α coefficients ranged from 0.819 to 0.899, and the CR values ranged from 0.941 to 0.978 in different occupational groups. Conclusion The GBS shows high reliability and validity, as well as good application effects in different occupational groups.

ABSTRACT

Liver diseases constitute a major healthcare burden globally, including acute hepatic injury resulted from acetaminophen overdose, ischemia-reperfusion or hepatotropic viral infection and chronic hepatitis, alcoholic liver disease (ALD), non-alcoholic fatty liver disease (NAFLD) and hepatocellular carcinoma (HCC). Attainable treatment strategies for most liver diseases remain inadequate, highlighting the importance of substantial pathogenesis. The transient receptor potential (TRP) channels represent a versatile signalling mechanism regulating fundamental physiological processes in the liver. It is not surprising that liver diseases become a newly explored field to enrich our knowledge of TRP channels. Here, we discuss recent findings revealing TRP functions across the fundamental pathological course from early hepatocellular injury caused by various insults, to inflammation, subsequent fibrosis and hepatoma. We also explore expression levels of TRPs in liver tissues of ALD, NAFLD and HCC patients from Gene Expression Omnibus (GEO) or The Cancer Genome Atlas (TCGA) database and survival analysis estimated by Kaplan-Meier Plotter. At last, we address the therapeutical potential and challenges by pharmacologically targeting TRPs to treat liver diseases. The aim is to provide a better understanding of the implications of TRP channels in liver diseases, contributing to the discovery of novel therapeutic targets and efficient drugs.

ABSTRACT

AIM: To compare the visual function of low-vision patients with primary retinal pigmentosa(RP)before and after wearing amber filter.METHODS: Self-control before and after study. A total of 30 patients(60 eyes)with low vision who were diagnosed with primary RP in the ophthalmology clinic of Xi'an No.1 Hospital from August 2021 to March 2022 were collected. The uncorrected distance visual acuity(UCDVA), best-corrected distance visual acuity(BCDVA), uncorrected near visual acuity(UCNVA), best-corrected near visual acuity(BCNVA), visual field and Farnsworth-Munsell(FM)-100 color visions were recorded before and after wearing amber filter. The contrast sensitivity(CS)in three visual environments including bright room, darkroom and darkroom with glare was measured and recorded respectively, and the changes of those parameters were analyzed before and after wearing filter.RESULTS: UCDVA and BCDVA after wearing the filter were better than those before wearing(t=-2.32, P&#x0026;#x003C;0.001; t=-6.77, P&#x0026;#x003C;0.001), while there was no statistically significant difference in UCNVA and BCNVA before and after wearing filter. The visual field index(VFI)after wearing filter was lower than that before wearing(t=8.62, P&#x0026;#x003C;0.001), and the mean defect(MD)of visual field was greater than that before wearing(t=7.73, P&#x0026;#x003C;0.001). FM100 color chess test showed that both total error score(TES)and partial error score(PES)in multiple regions were higher than those before wearing filter(P&#x0026;#x003C;0.001). After wearing, the CS of each frequency band in the environment of bright room and darkroom with glare was higher than that before wearing(P&#x0026;#x003C;0.001), and there was no statistically significant difference in each frequency band before and after wearing amber filter under the environment of darkroom without glare.CONCLUSION: Patients with low vision of primary RP showed improved UCDVA and BCDVA, but unchanged UCNVA and BCNVA after wearing amber filter, while the visual field and color discrimination were worse than those before wearing filter. The CS of the bright room and darkroom with glare environment was improved than before wearing filter, while there were no significant changes in CS under darkroom without glare.

ABSTRACT

Intermittent exotropia(IXT)is a common ophthalmic disease with high incidence, variable deviation, and varying degrees of impaired binocular visual function. The defect of binocular visual function is related to the changes of visual cortex. IXT involves the functional changes of many brain regions, including the cortical areas related to binocular fusion. After correcting the eye position, the abnormal changes of cerebral cortex still exist in some patients with IXT, and the recovery of binocular vision is still difficult. In order to solve these problems, visual perception training is gradually applied to the postoperative reconstruction of binocular visual function in patients with IXT. Visual perception training repairs the visual cortex from the brain level, improving the ability of the visual cortex to process information by constantly stimulating the visual center, thus repairing the visual central function, so that patients can obtain good binocular visual function, stabilize the eye position and reduce recurrence. This article reviews the mechanism of binocular visual impairment and the role of visual perception training in the treatment of IXT. It is hoped to provide more evidence for visual perception training to reconstruct postoperative binocular visual function and reduce the recurrence rate in patients with IXT.

ABSTRACT

Objective:To evaluate the efficacy and safety of phacoemulsification combined with gonioscopy-assisted angle plasty (Phaco-GAAP) for primary angle closure glaucoma (PACG) with cataract.Methods:A case series study was carried out.Twenty-five eyes of 22 patients with PACG and cataract were enrolled in Beijing Tongren Hospital from April 2022 to August 2022.All of the patients received Phaco-GAAP surgery.During the operation, viscoelastic-assisted goniosynechialysis was performed at first, followed by a secondary angle plasty for residual peripheral anterior synechiae (PAS) based on the quantified assessment by gonioscopy, and the extent of PAS was recorded intraoperatively.The operated eyes were followed at 1 day, 1 week, 1 month and 3 months after surgery to evaluate intraocular pressure (IOP), PAS range, the number of anti-glaucoma drugs application, operation-related complications, and success rate.The qualified success rate was defined as medicine-controlled IOP ≤21 mmHg after surgery, and complete success rate was defined as IOP ≤21 mmHg without any anti-glaucoma medication.This study complied with the Declaration of Helsinki and was approved by the Ethics Committee of Beijing Tongren Hospital (TRECKY2021-136). Written informed consent was obtained from each patient prior to entering the research cohort.Results:The extent of PAS was [270(225, 360)°], [165(110, 215)°] and [100(35, 175)°] at preoperation, first and secondary angle plasty, respectively, showing a significant difference among them ( χ2 =40.742, P<0.001). The PAS range was significantly reduced at first angle plasty in comparison with preoperation and was significantly reduced at secondary angle plasty in comparison with at first angle plasty (both at P<0.001), and the proportion of the angle PAS range ≥180° decreased from 48% to 24% after second angle plasty.In 13 eyes finished gonioscopy, the PAS range was [240(195, 305)°], [60(25, 182.5)°], [170(120, 275)°]and [180(140, 280)°]at preoperation, at the end of operation, postoperative 1 month and 3 months, respectively, with a significant difference ( χ2 =23.631, P<0.001). The PAS range was significantly smaller at postoperative 1 month, 3 months than that at preoperation (both at P=0.004) and larger than that at the end of operation ( P=0.011, P=0.003). The IOP was (40.19±17.23), (15.80±7.98), (13.89±5.09), (12.80±3.79) and(13.24±2.78) mmHg before operation and 1 day, 1 week, 1 month and 3 months after operation, respectively, showing a significant difference ( F=44.031, P<0.001), and the IOP was significantly reduced after operation (all at P<0.001). The PAS range at the end of operation was positively correlated with preoperation ( rs=0.409, P=0.042). The complete and qualified success rates were 95.8%, 95.8% for postoperative 1 month, 95.8% and 100% for postoperative 3 months, respectively.The primary complication was intraoperative anterior chamber angle hemorrhage, with an incidence of 68%. Conclusions:Phaco-GAAP can intraoperatively quantify PAS range and guide secondary angle plasty, therefore, it is an effective and safe surgical intervention for PACG with cataract.

ABSTRACT

ObjectiveTo understand the internet media information of COVID-19 in Shanghai in 2022, to provide evidence for health administration departments to respond to public health emergencies, and to establish a comprehensive public health media surveillance system. MethodsData on internet media information and the local COVID-19 epidemic data in Shanghai from January 1 to June 30, 2022 were collected and analyzed. ResultsA total of 90.197 3 million pieces of internet media information were monitored. The top four sources of the information were Weibo (36.84%), short videos (26.19%), internet media (14.47%), and forums (13.31%). The variation trend of daily internet media surveillance information was identified with the number of newly reported cases per day, and a correlation was found (r=0.770. After the seven-day moving average,r=0.796). Frequent keywords included Shanghai, cheer up, nucleic acid, new cases, local, asymptomatic, prevention and control, gratitude, isolation, epidemic prevention, supplies, pandemic response, patient, seeking help, and clearing the cases. Within the information on Weibo, in addition to netizens in Shanghai (7 823 100) who were highly concerned about the pandemic, netizens from Beijing (2 749 100), Guangdong Province (2 352 300), Jiangsu Province (2 189 100) and Zhejiang Province(1 532 100) also posted a relatively high amount of information related to COVID-19 in Shanghai. ConclusionThe outbreak of major infectious diseases triggers significant online activity, and platforms such as Weibo and short video platforms play crucial roles in disseminating internet media information. Weibo, short videos etc. are important platforms for current internet media information. Strengthening media information monitoring and analysis, paying close attention to hot events, taking timely response measures and actively engaging in risk communication contribute to the response and management of public health emergencies.

ABSTRACT

Background Cumulative fatigue without intervention will seriously threaten the physical and mental health of workers. Shift work and life satisfaction are strongly associated with fatigue accumulation. Objective To explore the effects of life satisfaction, shift work, and their interaction on cumulative fatigue in petrochemical employees, and to provide a scientific basis for preventing cumulative fatigue. Methods All staff of a petrochemical enterprise were selected by cluster sampling for a cross-sectional study from July to October 2021 in Jiangsu Province. A questionnaire designed by the project team was used to collect information on shift work; and life satisfaction and cumulative fatigue were investigated by the World Health Organization Five-item Well-Being Index and the Self-diagnosis Checklist for Assessment of Worker’s Fatigue Accumulation respectively. A logistic regression model was used to analyze the influences of life satisfaction and shift work on cumulative fatigue. Multiplicative and additive models were applied to analyze the interaction effect of life satisfaction and shift work. Results A total of 4066 questionnaires were returned, of which 3763 were valid, with an effective recovery rate of 92.5%. The percentage of cumulative fatigue in the petrochemical employees was 63.2% (2377/3763), and the percentages of low life satisfaction and shift work in the petrochemical employees were 53.6% (2016/3763) and 54.2% (2041/3763), respectively. The results of univariate analysis showed no significant difference in cumulative fatigue among different marital status groups (P=0.176), and there were statistically significant differences in cumulative fatigue among the petrochemical employees in different groups of age, gender, educational level, average monthly income, job title, length of service, working hours, night shift, smoking, drinking, physical exercise, life satisfaction, and shift work (P<0.001). After adjustment for covariates such as age, gender, educational level, average monthly income, job title, length of service, working hours, night shift, smoking, drinking, and physical activity, the unconditional logistic regression model showed that the risk of reporting cumulative fatigue in high life satisfaction participants was 0.129 (95%CI: 0.109, 0.154) times of that in participants of low life satisfaction; the risk of reporting cumulative fatigue in shift work participants was 3.792 (95%CI: 2.713, 5.300) times of that in no shift work participants; and the risk of reporting cumulative fatigue in participants with both high life satisfaction and shift work was 0.105 (95%CI: 0.081, 0.135) times of that in participants with low life satisfaction and shift work. The relative excess risk due to interaction, the attributable proportion due to interaction, and the synergy index of coexisting life satisfaction and shift work were −5.504 (95%CI: −7.247, −3.760), −4.728 (95%CI: −7.575, −1.880), and 0.029 (95%CI: 0.002, 0.351) respectively, which suggested that life satisfaction and shift work have an additive interaction effect on cumulative fatigue. A significant multiplicative interaction was also found between life satisfaction and shift work (OR=0.688, 95%CI: 0.476, 0.936). Conclusion Life satisfaction and shift work are the influencing factors of cumulative fatigue among petrochemical employees, and they interact with each other on the risk of cumulative fatigue. High life satisfaction can reduce the risk of accumulated fatigue associated with shift work.

ABSTRACT

Objective: To fabricate TiO2 nanotube material functionalized by antimicrobial peptide LL-37, and to explore its effects on biological behaviors such as adhesion and migration of human keratinocytes (HaCaT) and its antibacterial properties. Methods: The TiO2 nanotube array (NT) was constructed on the surface of polished titanium (PT) by anodization, and the antimicrobial peptide LL-37 was loaded on the surface of TiO2 nanotube (LL-37/NT) by physical adsorption. Three samples were selected by simple random sampling in each group. Surface morphology, roughness, hydrophilicity and release characteristics of LL-37 of the samples were analyzed with a field emission scanning electron microscope, an atomic force microscope, a contact angle measuring device and a microplate absorbance reader. HaCaT cells were respectively cultured on the surface of three groups of titanium samples. Each group had 3 replicates. The morphology of cell was observed by field emission scanning electron microscope. The number of cell adhesion was observed by cellular immunofluorescence staining. Cell counting kit-8 (CCK-8) assay was used to detect cell proliferation. Wound scratch assay was used to observe the migration of HaCaT. The above experiments were used to evaluate the effect of each group on the biological behavior of HaCaT cells. To evaluate their antibacterial effects, Porphyromonas gingivalis (Pg) was respectively inoculated on the surface of three groups of titanium samples. Each group had 3 replicates. The morphology of bacteria was observed by field emission scanning electron microscope. Bacterial viability was determined by live/dead bacterial staining. Results: A uniform array of nanotubes could be seen on the surface of titanium samples in LL-37/NT group, and the top of the tube was covered with granular LL-37. Compared with PT group [the roughness was (2.30±0.18) nm, the contact angle was 71.8°±1.7°], the roughness [(20.40±3.10) and (19.10±4.11) nm] and hydrophilicity (the contact angles were 22.4°±3.1° and 25.3°±2.2°, respectively) of titanium samples increased in NT and LL-37/NT group (P<0.001). The results of in vitro release test showed that the release of antimicrobial peptide LL-37 was characterized by early sudden release (1-4 h) and long-term (1-7 d) slow release. With the immunofluorescence, more cell attachment was found on NT and LL-37/NT than that on PT at the first 0.5 and 2.0 h of culture (P<0.05). The results of CCK-8 showed that there was no significant difference in the proliferation of cells among groups at 1, 3 and 5 days after culture. Wound scratch assay showed that compared with PT and NT group, the cell moved fastest on the surface of titanium samples in LL-37/NT group at 24 h of culture [(96.4±4.9)%] (F=35.55, P<0.001). A monolayer cells could be formed and filled with the scratch in 24 h at LL-37/NT group. The results of bacterial test in vitro showed that compared with the PT group, the bacterial morphology in the NT and LL-37/NT groups was significantly wrinkled, and obvious bacterial rupture could be seen on the surface of titanium samples in LL-37/NT group. The results of bacteria staining showed that the green fluorescence intensity of titanium samples in LL-37/NT group was the lowest in all groups (F=66.54,P<0.001). Conclusions: LL-37/NT is beneficial to the adhesion and migration of HaCaT cells and has excellent antibacterial properties, this provides a new strategy for the optimal design of implant neck materials.

ABSTRACT

Tuberculosis (TB) prophylactic therapy for latent infection, which can reduce the risk for the development of active TB, is an important measure in TB control. China recommends prophylactic therapy for latent tuberculosis infection (LTBI) in some key populations to reduce the risk for TB. Contacts of patients with multi-drug and rifampicin-resistant TB (MDR/RR-TB) are at high risk for the infection with drug-resistant pathogen, however, no unified prophylactic therapy regimen has been recommended for LTBI due to exposure to MDR/RR-TB patients. This paper summarizes the current MDR/RR-TB prophylactic therapy regimen and its protection effect based on the results of the retrieval of literature, guidelines, expert consensus and technical specifications to provide reference for the prevention and control of LTBI.

ABSTRACT

Objective: To determine the efficacy of eltrombopag for primary immune thrombocytopenia (ITP) in adults and the predictive factors for treatment-free response (TFR) . Methods: Clinical data of adults with ITP who received eltrombopag from June 14, 2013 to May 31, 2021 in the Hematology Department of Ruijin Hospital affiliated with Shanghai Jiao Tong University Medical College were retrospectively analyzed. The initial dose of eltrombopag was 25 mg/d, and the maximum dose was 75 mg/d; the dose was adjusted to maintain the platelet count to within 50-150×10(9)/L. Treatment was discontinued according either to the protocol, on the patient's wishes or doctor's judgment (prescription medication), or based on clinical trials. The efficacy of eltrombopag and factors for TFR among patients who achieved complete response and those who discontinued treatment were analyzed. Results: Overall, 106 patients with ITP (33 men and 73 women) were included in the study. The median age of patients was 50 (18-89) years. There were 2, 10, and 94 cases of newly diagnosed, persistent, and chronic ITP, respectively. The complete response rate was 44.3% (47/106), the response rate was 34.0% (36/106), and the overall response rate was 78.3% (83/106). Meanwhile, 83 patients who responded to treatment discontinued eltrombopag; of these, 81 patients were evaluated. Additionally, 17 patients (21.0%) achieved TFR. The median follow-up duration of patients who achieved TFR was 126 (30-170) weeks. The recurrence rate was 17.6% (3/17), and the relapse-free survival rate was 76.5%. The results of univariate analysis revealed that non-recurrence after discontinuation of other treatments for ITP (P=0.001), and platelet count and eltrombopag dose of ≥100×10(9)/L (P=0.007) and ≤25 mg/d (P=0.031), respectively, upon discontinuation of eltrombopag were predictors of TFR; these effects were attributed to prolonged effective duration of eltrombopag. Multivariate analysis showed that there was a correlation between non-recurrence and prolonged effective duration after discontinuation of other treatments for ITP (P=0.002) . Conclusion: Eltrombopag is effective for patients with ITP as it can result in TFR. Predictors for TFR include non-recurrence after discontinuation of concomitant ITP treatment, and platelet count and eltrombopag dose of ≥100 × 10(9)/L and ≤25 mg/d upon discontinuation of treatment, respectively.

ABSTRACT

Objective To compare the clinical effects of three treatment methods including systemic thrombolysis(ST),catheter-directed thrombolysis(CDT),and AngioJet percutaneous mechanical thrombectomy(PMT)in acute lower extremity deep venous thrombosis(LEDVT). Methods The data of 82 patients diagnosed with LEDVT in the Department of Vascular and Gland Surgery of the First Affiliated Hospital of Hebei North University from January 2017 to December 2020 were collected.The patients were assigned into a ST group(n=50),a CDT group(n=16),and a PMT group(n=16)according to different treatment methods.The efficacy and safety were compared among the three groups. Results Compared with that before treatment,the circumferential diameter difference of both lower limbs on days 1,2,and 3 of treatment in the ST,CDT,and PMT groups reduced(all P<0.001).The PMT group showed smaller circumferential diameter difference of lower limbs on days 1,2,and 3 of treatment than the ST group(all P<0.001)and smaller circumferential diameter difference of the lower patellar margin on day 1 of treatment than the CDT group(P<0.001).The PMT group showed higher diminution rate for swelling of the affected limb at the upper and lower edges of the patella than the ST group(P<0.001)and higher diminution rate for swelling at the upper edge of the patella than the CDT group(P=0.026).The incidence of complications after treatment showed no significant differences among the three groups(all P>0.05).The median of hospital stay in the PMT group was shorter than that in the ST and CDT groups(P=0.002,P=0.001).The PMT group had higher thrombus clearance rate than the ST group(P=0.002)and no significant difference in the thrombus clearance rate from the CDT group(P=0.361).The vascular recanalization rates in the PMT(all P<0.001)and CDT(P<0.001,P=0.002,P=0.009)groups 3,6,and 12 months after treatment were higher than those in ST group,and there were no significant differences between PMT and CDT groups(P=0.341,P=0.210,P=0.341). Conclusions ST,CDT,and PMT demonstrated significant efficacy in the treatment of LEDVT,and PMT was superior to ST and CDT in terms of circumferential diameter difference of the lower limbs,diminution rate for swelling of the affected limb,thrombus clearance rate,length of hospital stay,and long-term vascular recanalization.There was no obvious difference in safety among the three therapies.
