RESUMEN
Objectives: Pulmonary thromboembolism is a severe but probably underdiagnosed disorder. Patients with lower limb fractures are at high risk for pulmonary thromboembolism. This study aimed to demonstrate the early identification strategies for occult pulmonary thromboembolism. Methods: From January to December 2022, 18 patients diagnosed with pulmonary thromboembolism were reviewed for this study. Data on patients' demographics, laboratory test results, and radiographic findings were collected. Finally, the data was analyzed. Results: Eighteen patients with lower limb fractures were included in this study. All of them present different symptoms, including 12 cases (12/18, 66%) of unexplained decrease in oxygen saturation; 16 patients had deep vein thrombosis in the lower limbs, with nine cases involving proximal veins and seven involving distal veins. One patient had an antithrombin III level of 35%. Thirteen cases were diagnosed with pulmonary embolism using CT pulmonary angiography. Four patients had pulmonary embolisms incidentally detected during coronary CT angiography, and one patient during aortic CT angiography. Conclusion: Patients with lower limb fractures showing chest tightness and unexplained decrease in finger pulse oxygen levels should be assessed for pulmonary thromboembolism. Simultaneously, selecting appropriate diagnostic tools is essential to guaranteeing quick and accurate diagnosis.
RESUMEN
AIM: Smoking is harmful to human health. However, the relationship between smoking and blood pressure (BP) has not been consistent. This study aimed to analyse nurses' smoking behaviours and their relationship with BP. METHODS: This cross-sectional study recruited 128 009 nurses in 11 cities in China. They were surveyed with questionnaires including BP measurements. The main contents of the questionnaire included smoking status and other factors that might be associated with hypertension. Multiple linear regression analyses and binary logistic regression analyses were used to analyse the data. RESULTS: The results showed there was a significant difference in the smoking rate among nurses with different characteristics (P < 0.05). For both male and female nurses, smoking was associated with increased diastolic BP and mean arterial pressure, but only with increased systolic BP of male nurses. The prevalence of hypertension among male and female nurses was not related to smoking. CONCLUSION: Despite a relatively low overall smoking rate, rates among some groups are high. Different cities, hospitals, and departments can combine local data and conditions to formulate targeted tobacco control measures to improve nurses' physical and mental health.

OBJECTIVE: To compare the effects of active and passive calf muscle contraction on the hemodynamics of the lower extremity vein. METHODS: 30 females were selected by convenient sampling. The hemodynamic indexes of the common femoral vein were measured by Duplex ultrasound during the active ankle pump exercise, active circular exercise, passive ankle pump exercise, passive circular exercise, and massage the calf muscles. RESULTS: There was no significant difference in the velocity of common femoral vein when the subjects do active ankle pump exercise, active circular exercise, and massage the calf muscles (p > .05), but the velocity of common femoral vein was faster than that of passive ankle pump exercise and passive circular exercise (p < .01). CONCLUSION: The effects of active ankle exercise and massage on promoting venous blood return of lower extremity are better than that of passive ankle exercise.

OBJECTIVES: The purpose of this study was to investigate the incidence of deep vein thrombosis (DVT) and clarify the risk factors of DVT in patients with femoral neck fracture. METHODS: A self-designed questionnaire was used to collect the clinical data of 1209 patients with femoral neck fracture in our hospital from January 2019 to December 2019. The content of the questionnaire mainly includes general information, past medical history, history of present illness, operation related information, occurrence of DVT. The collected data were entered into Excel to analyze the incidence and risk factors of DVT in patients with femoral neck fracture. Chi square test and binary logistic regression model was used to screen the risk factors of DVT. RESULTS: 1209 cases of femoral neck fracture were included in this study. The incidence of DVT was 28.0% (339 patients). Among them, 71.7% (243 patients) were preoperative DVT and 28.3% (96 patients) were postoperative DVT. For the risk-factor analysis, gender, age, time from injury to hospitalization, operative method, anesthesia method and intraoperative blood loss were independent risk factors for DVT. CONCLUSION: The incidence of DVT in patients with femoral neck fracture is relatively high, and there are many related risk factors.

OBJECTIVES: Understanding the effect of night shift on hypertension risk in nurses is important to improve the health of nurses and ensure patient safety. This study aimed to evaluate the effect of the frequency and pattern of night shift on hypertension risk and the interaction of them in female nurses. METHODS: This cross-sectional study constituted 84â697 female nurses in 13 cities in China. The main contents of the survey included SBP, DBP, the frequency and pattern of night shift, and some other factors that might be associated with hypertension. Logistic regression analyses were used to calculate ORs and 95% CIs to estimate the effect of the frequency and pattern of night shift on hypertension risk and the interaction of them in relation to hypertension risk. RESULTS: Having more than 5 to 10 or more than 10 night shifts per month were significantly more likely to be hypertensive (OR 1.19, 95% CI 1.10-1.28; OR 1.32, 95% CI 1.13-1.54), whereas having less than or equal to 5 night shifts per month was not (OR 1.05, 95% CI 0.95-1.16). The patterns of night shift were all associated with a higher probability of hypertension and participants engaging in rapidly rotating night shift had a lower OR (1.14) than those having slowly rotating night shift (1.23) and permanent night shift (1.46). No significant interaction was observed between the frequency and the pattern of night shift (Pinteractionâ=â0.281). CONCLUSION: The frequency and pattern of night shift were associated with hypertension risk in female nurses and no significant interaction was observed between them.

PURPOSE: The purpose of this study was (1) to compare the effects of ankle pump exercise(APE) frequency on hemodynamics of the common femoral vein(CFV) and (2) to analyse the relationship between APE duration and lower limb fatigue. METHODS: Twenty-seven males and thirty-three females performed APE. Among them, there were thirty participants with non-lower limb fracture (N-LLF) and thirty participants with lower limb fracture (LLF).The colour doppler ultrasound was used to record the time-averaged mean velocity (TAMV) of common femoral venous flow when the participants at rest and move at different frequencies of 6 times/min, 10 times/min, 30 times/min, 60 times/min. The ratings of perceived exertion (RPE) was used to assess the lower limb fatigue of the participants when performing APE at the frequency of 60 times/min after 1âmin, 2âmins, 3âmins, 4âmins and 5âmins. RESULTS: With the increase of frequency, TAMV increased significantly in both the participants with N-LLF and LLF (pâ<â0.01). The TAMV were 19.82±3.86, 33.78±8.76, 37.06±8.67, 43.82±10.40, 52.18±10.53, respectively in the participants with N-LLF and 16.98±3.01, 22.20±4.96, 24.01±5.78, 29.20±7.05, 35.75±9.28, respectively in the injured limb of patients with LLF when at rest and moving at the frequency of 6 times/min, 10 times/min, 30 times/min, 60 times/min. There was a positive correlation (pâ<â0.01) between lower limb fatigue and exercise duration.When the RPE was 16 points (the corresponding fatigue degree is "tired"), the exercise duration of the participants with N-LLF was 3âmins and that of the injured limb of patients with LLF was 2âmins. CONCLUSIONS: Both fast and slow-frequency APE can promote venous blood return in the lower limb. Despite of the equivalent APE duration, fast-frequency APE can promote venous blood return more effectively. When the frequency of APE was 60 times/min, participants with N-LLF can exercise for 3âmins, and the injured limb of patients with LLF can exercise for 2âmins.
