Comparative study on electrocardiograms and serological examinations of acute pulmonary embolism and acute non-ST elevation myocardial infarction.

BACKGROUND: The aim of this study was to investigate the value of electrocardiograms (ECGs) and serological examinations in the differential diagnosis of acute pulmonary embolism (APE) and acute non-ST elevation myocardial infarction (NSTEMI) in order to reduce the rate of clinical misdiagnosis. METHODS: The clinical data of 37 patients with APE and 103 patients with NSTEMI admitted to our hospital were retrospectively analyzed. The differences in the clinical manifestations, ECGs, myocardial zymograms, D-dimers, and troponin (cTn) of the two groups were compared. RESULTS: In the patients with APE, the main symptom-found in 25 cases (67.56%)-was dyspnea, while in the patients with NSTEMI, the main symptom-found in 52 cases (50.49%)-was chest tightness. The incidences of sinus tachycardia and SI QIII TIII in the group of patients with APE were higher than in the group of patients with NSTEMI, and the difference was statistically significant (p < .05). There was no statistical significance in the difference of aspartate aminotransferase and lactate dehydrogenase (LDH) in the two groups (p > .05), although there was a statistically significant difference of creatine kinase (CK) and the creatine kinase isoenzyme-MB (CK-MB) in the two groups (p < .05). The levels of D-dimers and cTn were increased in both groups, but the level of D-dimers in the group of patients with APE was higher than that in the group of patients with NSTEMI. CONCLUSION: With the occurrence of clinical manifestations like dyspnea, chest tightness, chest pain, and palpitation of unknown causes, the possibility of APE and NSTEMI should be considered.

Analysis of the difference in pulse oxygen saturation between the ventral and dorsal fingers.

AIM: This study aimed to investigate the effect of different probe placements on the ventral and dorsal sides of the same finger using pulse oxygen saturation monitoring. METHODS: This clinical trial used a convenience sampling method in patients admitted to the Second Hospital of Hebei Medical University. We enrolled 1330 patients from March to July 2018, including patients who were hospitalized in the intensive care unit (n = 258) and in the general ward (n = 1072). Pulse oxygen saturation measurements obtained from the ventral and dorsal sides of the same finger were compared. This work adhered to the STROBE checklist requirements. RESULTS: We found that pulse oxygen saturation measurements between the dorsal and ventral sides of a finger were not affected by different fingers, disease types, the application of a ventilator, vasoactive drugs, the conscious state of the patient or the instrument model. CONCLUSION: Our findings suggested no significant difference in saturation measurements with variation in the placement of the pulse oxygen saturation measurement instrument between the dorsal and ventral sides of a finger, regardless of illness severity. We believe that these results could simplify the monitoring procedures performed by nurses and eliminate worries concerning the inaccuracy of data because of varied probe positions.

A cross-sectional study of the interaction between night shift frequency and age on hypertension prevalence among female nurses.

Night shift is a common work schedule. This study aimed to analyze the interaction between age and frequency of night shift on the hypertension prevalence. A census questionnaire was conducted in 512 medical institutions in 11 cities of Hebei Province. One lakh twenty-one thousand nine hundred three female nurses were included in this study. Binary Logistic regression analysis was done by SPSS Version 26.0. The youngest age group without night shift was used as the reference group. The odds ratio was calculated by different combinations of interaction items. Interaction coefficients were calculated by an Excel table designed by Andersson. Compared with the 18-25 year old ones without night shift, there existed an additive interaction between the age of 36-45 and more than 5-10 night shifts per month on hypertension prevalence. Odds ratio, the relative excess risk of interaction, the attributable proportion of interaction, and the synergy index and their 95% confidence intervals were 2.923(2.292-3.727), 0.631(0.309-0.954), 0.216(0.109-0.323), 1.488(1.158-1.913). Additive interaction was also found between the age of 36-45 and more than 10 night shifts per month. OR, RERI, API, SI, and their 95% confidence intervals were 3.430(2.273-5.175) 1.037(0.061-2.013), 0.303(0.089-0.516), and 1.746(1.093-2.788). There also existed an additive interaction between the age of 46-65 and more than 5-10 night shifts per month on hypertension prevalence. OR, RERI, API, SI, and their 95% confidence intervals were 7.398(5.595-9.781) 1.809(0.880-2.739), 0.245(0.148-0.341), and 1.394(1.199-1.622).There existed interaction between specific age groups and night shift frequency on the prevalence of hypertension among female nurses.

Effect of frequency and pattern of night shift on hypertension risk in female nurses: a cross-sectional study.

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 84 697 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 (Pinteraction = 0.281). CONCLUSION: The frequency and pattern of night shift were associated with hypertension risk in female nurses and no significant interaction was observed between them.

Hypertension prevalence alteration in 92 815 nurses based on the new standard by 2017 ACC/AHA hypertension guideline: observational cross-sectional study from China.

OBJECTIVES: This study aimed to elucidate the status of hypertension and to analyse the hypertension changes in prevalence, awareness, treatment and control rate among the portion of Chinese nursing staff based on the 2017 American College of Cardiology (ACC)/American Heart Association (AHA) High Blood Pressure Guideline and the 2010 Chinese Guideline for the Management of Hypertension. DESIGN: Cross-sectional study. SETTING: 512 medical institutions in 13 cities in Hebei Province. PARTICIPANTS: The candidates of registered nurses from 512 medical institutions in 13 cities in Hebei Province (N=143 772) were invited to participate in the survey, and few of them who refused to participate were excluded from the research group based on the reasons that 93 603 incumbent nurses at the age of 18-65 accepted to the survey and submitted questionnaires online. Undoubtedly, a response rate of 65.11% was achieved. After excluding 788 individuals with incomplete information in the questionnaires, 92 815 participants were included in the final analysis. MAIN OUTCOME MEASURES: The prevalence, awareness, treatment and control rates of hypertension. RESULTS: 92 815 participants were included in the final analysis, among which consisted of 3677 men (3.96%) and 89 138 women (96.04%). The mean age of the participants was 31.65 (SD=7.47) years.We demonstrated that 26 875 nursing staff were diagnosed as having hypertension according to the new standard by the 2017 ACC/AHA guideline, more than 20 551 cases compared with the previous threshold on the 2010 Chinese guideline. The prevalence of hypertension among nursing staff was 28.96% in the context of the 2017 ACC/AHA guideline, 3.25 times higher than that (6.81%) evaluated by the criteria of the 2010 Chinese guideline. However, the awareness, treatment and control rate (13.50%, 10.73% and 0.81%) were 3.25, 3.22 and 17.48 times lower than those (57.37%, 45.30% and 14.97%) based on the 2010 Chinese guideline, respectively. CONCLUSIONS: This research illustrated that it was crucial to improve the awareness rate, drug treatment rate and control rate of hypertension for nurses. Meanwhile, according to the 2017 ACC/AHA guideline, the prevalence of hypertension in China will increase significantly, which poses a more severe challenge to the management of hypertension in China.
