Background The adverse effects of long working hours, shift rotation, and job stress on the physical and mental health of occupational populations require urgent attention. Objective To investigate and compare the positive rates of WMSDs between different industries, analyze the exposure status of long working hours, shift rotation, and job stress among key occupational groups, and evaluate the impacts of these factors on WMSDs in the manufacturing and service industries. Methods The study subjects were derived from key occupational populations in Yunnan Province, recruited by the Chinese National Occupational Health Literacy Monitoring Survey in 2022. A cross-sectional design was used for this survey. The key occupational populations were recruited from the secondary industry (manufacturing industry, metal mining and beneficiation industry, and non-metal mining and beneficiation industry) by stratified random sampling and from the tertiary industry (medical and healthcare industry, education industry, environmental sanitation industry, transportation industry, and express/takeaway delivery industry) by proportional probability sampling, and 12014 front-line workers were finally included as survey participants. General information, work-related factors (shift rotation, weekly working hours, job stress, etc.) and WMSDs assessment results were obtained through a web-based self-reported questionnaire, and the associations of long working hours, shift rotation, and job stress with WMSDs were analyzed using χ² test and logistic regression. Results The average positive rate of WMSDs among the key occupational groups in Yunnan Province was 77.2%. The positive rate of WMSDs in the secondary industry group was 69.4%, while it was 81.6% in the tertiary industry group, with a statistically significant difference (P<0.001). Among the eight surveyed sectors, the education sector had the highest positive rate of WMSDs (94.2%). The single-site WMSDs mainly involved the neck, shoulders, and low back. In the secondary industry, WMSDs was reported in 1−2 body parts, while in the tertiary industry, WMSDs was mainly reported in multiple (≥5) body parts. Long working hours (OR: 1.119, 1.165, 1.163, respectively), shift rotation (OR: 1.094, 1.199, 1.230, respectively), and job stress (OR: 1.795, 1.854, 2.006, respectively) were risk factors for WMSDs in the neck, shoulder, or low back, and all three were also risk factors for multi-site WMSDs. Moreover, as the number of involved body parts increased, the effects of long working hours and job stress became more pronounced. For 1-2, 3-4, and 5 or more body parts compared to no pain reported, their OR values were 0.971 (95%CI: 0.871, 1.082), 1.133 (95%CI: 1.004, 1.279), and 1.285 (95%CI: 1.155, 1.429) for long working hours, respectively, and the OR values were 1.009 (95%CI: 0.878, 1.160), 1.360 (95%CI: 1.174, 1.575), and 2.797 (95%CI: 2.471, 3.166) for job stress, respectively. Conclusion The positive rate of WMSDs is higher in the tertiary industry than that in the secondary industry among the key occupational groups in Yunnan Province. Long working hours, rotating shift work, and job stress could significantly increase the risk of WMSDs.

Among them, the content validity quality of the Maternal-fetal Attachment Tool was sufficient (evidence quality was advanced), the structural validity quality was uncertain (evidence quality was intermediate), the internal consistency quality was sufficient (evidence quality was advanced) and the hypothesis testing quality was sufficient (evidence quality was advanced), which was recommended at level A.Conclusions:This study systematically evaluates seven measurement tools for maternal-infant attachment, among which the Maternal-fetal Attachment Tool is class A tool and is recommended for use.

Objective:To investigate the value of 3D CT reconstruction in diagnosis of chronic lateral ankle instability (CLAI) combined with syndesmotic diastasis (SD).Methods:A retrospective study was conducted to analyze the clinical data of 160 patients with CLAI who had been examined by arthroscopy from January 2018 to September 2022 at Department of Foot and Ankle Surgery, Wuhan Fourth Hospital. There were 64 males and 96 females with an age of (39.8±12.6) years. Eighty-one left and 79 right feet were affected; the time from injury to surgery was (27.3±11.6) months. The patients were divided into a widened interval group and a normal interval group according to the syndesmotic width measured, with 2 mm as a critical value. After preoperative 3D CT reconstruction, the differences in anterior tibiofibular distance, posterior tibiofibular distance, the narrowest tibiofibular distance, fibular translation, fibular rotation, and syndesmotic area (SA) were compared between the 2 groups. Univariate and multivariate analyses were performed successively to identify the risk factors. The receiver operating characteristic (ROC) curve was used to identify the best predictive factor and critical value. According to the findings of previous research, the above analyses were repeated to determine the best predictive factor and critical value respectively in the sex subgroup, fibular morphology subgroup and incisura feature subgroup.Results:The binary logistic regression showed that SA was a risk factor for CLAI combined with SD ( OR=1.196, 95% CI: 1.122 to 1.275, P < 0.001). The ROC curve revealed an area under curve of 0.847 and the difference critical value of 22.06 mm 2 that indicated a sensitivity of 80.4% and a specificity of 78.9%, respectively. Subgroup analyses showed that SA was suitable for male and female patients and patients with different fibular morphologies and incisura features but the difference critical values were different. Conclusion:In 3D CT reconstruction, measurement of SA may help the diagnosis of CLAI combined with SD.

Objective To understand the drug resistance surveillance situation of Mycobacterium tuberculosis in Hainan Province from 2018 to 2022, analyze the drug resistance status and trends of Mycobacterium tuberculosis in Hainan Province, and provide scientific basis for the formulation of tuberculosis prevention and treatment strategies. Methods A total of 2 481 sputum culture-positive isolates from pulmonary tuberculosis patients collected from 2018 to 2022 were subjected to strain identification and drug sensitivity testing. Strain identification was performed using the p-nitrobenzoic acid (PNB) inhibition test, and the sensitivity test for six anti-tuberculosis drugs, including Rifampicin (RFP), Isoniazid (INH), Streptomycin (SM), Ethambutol (EMB), Ofloxacin (OFX), and Kanamycin (KM), was conducted using the solid culture proportion method. The drug sensitivity results were statistically analyzed. Results Of the 2 481 isolates, 2 211 were identified as Mycobacterium tuberculosis complex (MTBC). The overall drug-resistance rate was 19.9% (441/2 211). The drug resistance rates for initial-treatment and retreatment patients were 15.7% (271/1 729) and 35.3% (170/482) respectively, with a statistically significant difference (χ2=90.65, P<0.01). The mono-resistance rate (MR) was 6.0% (132/2 211), with monoresistance rates of 5.6% (97/1 729) for initial-treatment patients and 7.3% (35/482) for retreatment patients, with no statistically significant difference (χ2=1.83, P>0.05). The overall poly-resistance rate (PR) was 4.1% (91/2 211), with polyresistance rates of 3.5% (61/1 729) for initial-treatment patients and 6.2% (30/482) for retreatment patients. The overall multidrug-resistance rate (MDR) was 8.0% (176/2 211), with multidrug resistance rates of 4.2% (72/1 729) for initial-treatment patients and 21.6% (104/482) for retreatment patients. According to the χ2 test, the retreatment group had significantly higher rates of polyresistance and multidrug resistance than the initial-treatment patient group, with statistically significant differences (χ2=6.94, P<0.01; χ2=155.98, P<0.01). The resistance rates to individual drugs in descending order were 11.6% (251/2 211) to INH, 11.4% (255/2 211) to RFP, 8.6% (191/2 211) to SM, 8.2% (181/2 211) to OFX, 4.0% (88/2 211) to EMB, and 1.6% (35/2 211) to KM. Conclusions The overall drug-resistance rate, poly-resistance rate, and multidrug resistance rate of Mycobacterium tuberculosis in retreatment patients in Hainan Province are higher than those in initial-treatment patients. Standardized treatment and management of TB patients are particularly important.

Acute poisoning represents a prevalent critical illness jeopardizing patient survival. Early, precise assessment of the condition and subsequent appropriate therapeutic intervention are pivotal in enhancing treatment success rates. Currently, a standardized approach to evaluating the severity of acute poisoning is lacking. Various scoring systems, including Poisoning Severity Score (PSS) , Modified Early Warning Score (MEWS) , and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) , offer valuable insights into acute poisoning assessment. Nevertheless, the distinct attributes of each scoring system constrain their broad clinical utility. Confronted with the intricate clinical demands of acute poisoning, the adoption of staged and dynamic assessment strategies is imperative to ascertain the condition of acute poisoning patients with greater accuracy.

Objective:To explore the clinical efficacy of reconstructing the calcaneocuboid and calcaneonavicular ligaments with the autologous semitendinosus for chronic bifurcate ligament injury.Methods:A retrospective study was conducted to analyze the clinical data of 12 patients with chronic bifurcate ligament injury who had been treated by anatomical reconstruction with the autologous semitendinosus from March 2018 to January 2021 at Department of Foot and Ankle Surgery, The Fourth Hospital of Wuhan. There were 4 males and 8 females with an age of (41.4±9.6) years. Seven left and 5 right feet were affected; the time from injury to surgery was (9.3±4.3) months. The surgical efficacy was evaluated based on anteroposterior and lateral imaging assessments of foot weight-bearing at 6 months postoperation, comparison of the visual analogue scale (VAS) pain scores for foot weight-bearing walking and the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot scores between preoperation and the last follow-up, stress test for stability of the transverse tarsal joint, recovery of movement, and occurrence of complications.Results:All patients were followed up for (18.4±4.0) months. Their sports activities were completely resumed after postoperative (6.8±3.9) months. Primary wound healing was achieved in all patients. One patient suffered from cutaneous nerve lesion and skin numbness, the symptoms of which disappeared after conservative treatment. Double harmonic curves were observed on the anteroposterior and lateral imaging films of foot weight-bearing in all patients. The spaces in the calcaneocuboid and the calcaneonavicular joints were normal, the articular positions were matched, and the calcaneocuboid joint was stable without recurrence or worsening of displacement. The VAS decreased significantly from preoperative 6.5 (5.6, 7.0) to 0.0 (0.0, 1.0) at the last follow-up, and the AOFAS mid-foot score increased significantly from preoperative (55.6±8.8) points to (92.3±2.6) points at the last follow-up ( P<0.05). The stress test for the stability of the transverse tarsal joint showed joint stability. Conclusion:Reconstruction of the calcaneocuboid and calcaneonavicular ligaments using the autologous semitendinosus is an alternative treatment for patients with chronic bifurcate ligament injury, because it can restore the stability of the bifurcate ligament and obviously improve the foot and ankle functions with limited postoperative complications.

Objective:To assess the efficacy of non-pharmaceutical intervention on improving sleep quality in pregnant women by network Meta-analysis.Methods:Randomized controlled clinical trials on non-pharmaceutical intervention to improve sleep quality in pregnant women were searched on Cochrane Library, PubMed, Web of Science, Embase, China Biology Medicine disc, CNKI and Wanfang Database by computer, and the search time limit was from the establishment of databases to December 2022. Two researchers independently screened the literature, extracted data and evaluated the risk of bias in the included studies. Stata 14.0 software was used to conduct a network meta-analysis.Results:Finally, a total of 26 randomized controlled trial were included, including 2 363 patients and 7 non-pharmaceutical intervention measures. The best probability ranking results of network meta-analysis showed that in terms of total score evaluation of Pittsburgh Sleep Quality Index, relaxation intervention, traditional Chinese medicine treatment, psychological intervention, exercise intervention, music therapy, sleep health education and routine nursing were ranked from high to low. In terms of dimensional evaluation of Pittsburgh Sleep Quality Index, relaxation intervention, traditional Chinese medicine treatment, psychological intervention and music therapy had better effects.Conclusions:Current evidence suggests that relaxation intervention, traditional Chinese medicine treatment, psychological intervention and music therapy may be more effective interventions in improving the sleep quality of pregnant women.

Objective To investigate etiologic characteristics of hand, foot, and mouth disease (HFMD) in a sentinel hospital in Guangzhou from 2017 to 2021, and to provide a scientific basis for the prevention and control of HFMD. Methods Descriptive epidemiologic methods were used to analyze the etiologic characteristics of mild cases of HMFD during 2017-2021. Results A total of 1 633 specimens of mild cases of HMFD were collected from 2017 to 2021. The total enterovirus (EV) positive rate was 78.41%, among which the positive rates of the main pathogen Cox A6, Cox A16, Cox A10, and EV71 were 40.83%, 17.68%, 6.13%, and 1.62%, respectively. The total positive rate of enteroviruses and the positive rate of enteroviruses of all types in each year were statistically different (P<0.001). In 2017-2021, the prevalence of HFMD in Guangzhou was mainly Cox A6, followed by Cox A16 which had the highest positive rate in 2018 (24.62%). The positive rate of EV71 decreased year by year. Cox A6 was highly prevalent from June to December every year, while the detection rate of Cox A16 was high from April to August every year. The positive detection rate of EV71 was high from January to May in 2017 and low from 2018 to 2021, with no epidemic peak. Conclusion From 2017 to 2021, the main pathogen of HMFD in Guangzhou is Cox A6, not EV71 or CoxA16, which suggests that it is of great significance to strengthen the monitoring of epidemic trend of HFMD for the prevention and control of HFMD.
