RESUMEN
Based on multimodal measurement methods of NASA task load index (NASA-TLX), task performance, surface electromyography (sEMG), heart rate (HR), and functional near-infrared spectroscopy (fNIRS), this study conducted experimental measurements and analyses under 16 different load levels of physical fatigue and mental fatigue combination conditions. This study observed the interaction between physical fatigue and mental fatigue at different levels, and at the subjective level, the effect of physical fatigue on mental fatigue was greater than that of mental fatigue on physical fatigue. Secondly, the results of fNIRS analysis showed that the premotor cortex is affected by physical fatigue, and the dorsolateral prefrontal cortex is affected by mental fatigue. Finally, this study constructed a fatigue classification model with an accuracy of 95.3%, which takes multimodal physiological data as input and 16 fatigue states as output. The research results will provide a basis for fatigue analysis, evaluation, and improvement in complex working situations.
Based on multimodal measurement methods of NASA-TLX, task performance, sEMG, HR, and fNIRS, this study illustrated the relationship between physical fatigue and mental fatigue, and proposed a classification method for different fatigue situations.
RESUMEN
BACKGROUND: The performance of healthcare workers directly impacts patient safety and treatment outcomes. This was particularly evident during the coronavirus disease 2019 (COVID-19) pandemic. OBJECTIVE: This study aimed to analyze research trends on factors influencing work performance among healthcare workers through bibliometric analysis and conduct a comparative analysis from macro and micro perspectives before and after the COVID-19 pandemic to complement the existing research. METHODS: This study involved a bibliometric analysis of 1408 articles related to work performance in the healthcare field published between 2010 and 2023, using the Web of Science, Scopus, and PubMed databases, and 37 articles were selected to determine the factors influencing work performance. RESULTS: By conducting a bibliometric analysis of the articles based on country, institution, journal, co-cited references, and keywords, this study identified a significant growth trend regarding the factors influencing work performance in the healthcare field, and research hotspots shifted from organizational factors like standard towards psychological factors such as burnout, anxiety, and depression following the outbreak of the COVID-19 pandemic. Subsequently, this study extracted 10 micro-level and 9 macro-level influencing factors from the selected articles for supplementary analysis. Furthermore, this study conducted a comparative analysis of the impact of these factors on work performance before and after the COVID-19 pandemic. CONCLUSIONS: This study addressed the limitations of previous studies regarding incomplete extraction of factors influencing work performance and unclear comparisons of parameters before and after the COVID-19 pandemic. The findings provide insights and guidance for improving the performance of healthcare workers.
RESUMEN
Background: The aim of the present study was to estimate the incidence, years lived with disability (YLDs), and cause of eye injury at global, regional, and national levels by age and sex based on the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. Methods: This is a retrospective demographic analysis based on aggregated data. GBD 2019 included the burden of eye injury worldwide and its temporal and spatial characteristics in the past three decades. The Bayesian meta-regression tool and DisMod-MR 2.1 were used to analyse the estimates based on a linear regression mode of the age-standardised rates (ASR). Average annual percent change (AAPC) was calculated to represent the temporal trends of the ASR. Findings: Globally, there were 59,933.29 thousand (95% uncertainty interval [UI]: 45,772.34-77,084.03) incident cases and 438.4 thousand (95% UI: 132.44-898.38) YLDs of eye injury in 2019. Both the ASR of incidence and YLDs decreased from 1990 to 2019, with AAPC -0.46 (95% confidence interval [CI]: -0.52 to -0.39) and -0.45 (95% CI: -0.52 to -0.39), respectively. Males had higher rates of incidence and YLDs in all age groups. Young and middle-aged adults had higher disease burdens. Regionally, Australasia had the highest ASR of YLDs to be 9.51 (95% UI: 3.00-19.58) per 100,000. Nationally, New Zealand had the highest burden of eye injury to be 11.33 (95% UI: 3.57-23.10) per 100,000. Foreign bodies, exposure to mechanical forces, and falls were the main causes of global eye injury burden in 2019, and there was an increased worldwide burden due to road injuries and executions and police conflict compared with 1990. Interpretation: Our findings suggest that the incidence and burden of eye injury have decreased over the last 30 years, while the absolute number of eye injuries has substantially increased, representing a major public health concern. Males and young adults were affected to a greater degree than females and elder individuals. More attention should be paid to road injuries and executions and police conflict in order to prevent eye injury.

RESUMEN
BACKGROUND: Venous thromboembolism (VTE) is a major cause of unexpected and perioperative in-hospital deaths. It is characterized by high morbidity, high mortality, high misdiagnosis rate, and high missed diagnosis rates. VTE is a common postoperative complication in cancer patients. VTE is preventable, and early identification of risk factors leading to VTE and appropriate early preventive actions can reduce its occurrence and mortality. Presently, there is no uniform standard for the prevention and control of VTE in clinical practice, and hospitals in China lack mature and effective protocols for the assessment, prevention, and treatment of VTE. AIM: To explore whether an early warning program could influence the occurrence of deep vein thrombosis (DVT) postoperatively. METHODS: This is a comparative retrospective cohort study, which enrolled patients who underwent laparotomic or laparoscopic gastrointestinal tumor resection for gastrointestinal cancer between January 2016 and December 2019. Patients were divided into a control group and an early warning group depending on whether or not the early warning program was implemented. A venous thromboembolism prevention and control team was established. The outcomes included the occurrence of DVT, the correct rate of VTE assessment, the coagulation indicators, and the mastery of VTE knowledge by the nurses. RESULTS: A total of 264 patients were included in this study, with 128 patients in the control group and 136 patients in the early warning group. The occurrence rate of DVT in the early warning group was 6.6% (9/136), compared with 14.1% (18/128) in the control group (P < 0.05). The correct rates of VTE risk assessment by the nurses and standard implementation rate of VTE preventive measures were 86.8% vs 65.6% and 80.2% vs 57.8% in early warning and control groups, respectively (all P < 0.001). The independent factors associated with postoperative DVT occurrence were age (OR = 1.083, 95%CI: 1.070-3.265, P = 0.032), Hyperlipidemia (OR = 1.127, 95%CI: 1.139-2.564, P = 0.042), preoperative high VTE risk (OR = 2.131, 95%CI: 1.085-5.178, P = 0.001), time of operation (OR = 2.268, 95%CI: 2.005-5.546, P = 0.026) and not adoption of early warning prevention (OR = 3.747, 95%CI: 1.523-6.956, P = 0.017). CONCLUSION: The early warning strategy was independently associated with the decreasing occurrence of VTE, and it might be suitable for protection from VTE in patients undergoing gastrointestinal cancer surgery.
