RESUMO
Objective:To investigate and analyze the psychological stress status and influencing factors of medical staff in comprehensive grade A hospitals.Methods:This was a cross-sectional survey using a convenient sampling method. A questionnaire survey was conducted among 2 048 staff members of the Affiliated Hospital of Qingdao University from February 25 to June 16, 2022. The questionnaires included the Self-rating Stress Questionnaire (SSQ-53), the Self-rating Anxiety Scale, and the Self-rating Depression Scale. A total of 2 048 questionnaires were distributed and 2 048 were collected. Among them, 2 006 (97.95%) were valid questionnaires, and 2 006 medical staff were ultimately included in the analysis. According to the results of the scale, they were divided into the increased psychological stress group and the non increased psychological stress group. Descriptive analysis, independent sample t-test/chi-square test, correlation analysis, and other methods were used to analyze the psychological stress status of medical staff and the distribution of related factors, and multivariate logistic regression was used to analyze their influencing factors. Results:A total of 310 (15.5%) out of 2 006 study subjects showed increased psychological stress. Women had a statistically significant increase in physical (14.7% vs 8.0%, χ2=12.40, P<0.001) and emotional dimensions (18.2% vs 13.5%, χ2=5.04, P=0.025) of stress compared to men. The level of psychological stress was positively correlated with anxiety and depression ( r=0.810, 0.749, respectively, P<0.001). Univariate analysis showed that those who were women ( χ2=6.76, P=0.009), with low education backgrounds ( Z=-2.50, P=0.012), nurses ( χ2=15.72, P<0.001), or working in emergency departments ( χ2=13.64, P=0.009) had a higher rate of increased psychological stress, while the serum calcium level in the increased psychological stress group was lower than that in the non increased psychological stress group ( t=2.82, P=0.005). Multivariate analysis showed that low educational backgrounds ( OR=2.238, 95% CI: 1.090-4.597, P=0.028) and working in emergency department ( OR=1.589, 95% CI: 1.012-2.493, P=0.044) were independent risk factors for increased psychological stress of medical staff. Working in administrative and logistics departments ( OR=0.466, 95% CI: 0.229-0.950, P=0.036) and serum calcium level ( OR=0.213, 95% CI: 0.059-0.760, P=0.017) were negatively correlated with increased psychological stress. Conclusions:In comprehensive grade A hospitals, medical staff working in the emergency department or with lower educational backgrounds face greater psychological stress. Serum calcium level is negatively correlated with increased psychological stress, but the causal relationship needs further study.
RESUMO
Objective:To compare the ability of triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio and triglyceride-glucose index (TyG) in identifying nonalcoholic fatty liver disease (NAFLD).Methods:A total of 11 524 eligible subjects who underwent physical examination in the Affiliated Hospital of Qingdao University from January to December in 2018 were selected in this research. The correlation between TG/HDL-C, TyG and NAFLD was analyzed by using binary logistic regression. The receiver operating characteristic (ROC) curves of TyG and TG/HDL-C were drawn for identifying NAFLD in male and female, and their diagnostic value for NAFLD was compared.Results:The prevalence of NAFLD increased with TG/HDL-C and TyG. After adjusting for confounding factors, when compared with that in the first quartile group of TG/HDL-C, the odds ratios (OR) and 95% confidence intervals ( CI) of NAFLD risk in the second, third and fourth quartile groups of TG/HDL-C was 2.380 (2.039-2.779), 3.902 (3.342-4.555) and 7.903 (6.745-9.259), respectively. Compared with that in the first quartile group of TyG, the OR (95% CI) of NAFLD risk in the second, third and fourth quartile groups of TyG was 2.243 (1.923-2.617), 3.918 (3.363-4.565) and 9.002 (7.676-10.559), respectively. The area under the curve (AUC) of TG/HDL-C and TyG in identifying NAFLD in male was 0.746 and 0.744, respectively, and there was no significant difference between the two indexes ( P=0.509 1). The AUCs of TG/HDL-C and TyG in identifying NAFLD in female was 0.785 and 0.799, respectively, and the difference was statistically significant ( P<0.001). The cut-off point of TG/HDL-C for identifying NAFLD in male was 1.02, and the cut-off point of TyG for identifying NAFLD in female was 8.55. Conclusions:TG/HDL-C and TyG are closely related to NAFLD in adults. There is no difference between TG/HDL-C and TyG in evaluating NAFLD in male, while TyG is better than TG/HDL-C in evaluating NAFLD in female.
RESUMO
Objective: To investigate the association between the CYP3A5 genetic polymorphism and the serum concentrations of carbamazepine (CBZ), to provide guidance for individualized drug dosing. Methods: Eighty-four epilepsy patients taking CBZ were included in this study. Their clinical data were recorded and CBZ serum concentrations were measured. The CYP3A5 6986 genetic polymorphism was assessed using a polymerase chain reaction-restriction fragment length polymorphism (PCRRFLP) assay. Patients were divided according to genotype into CYP3A5 expressor (CYP3A5*1/*1 genotype and CYP3A5*1/*3 genotypes) and non-expressor groups (CYP3A5*3/*3). The two groups were compared for the total dose of CBZ, dose of CBZ/kg body weight, serum drug concentration, dose-corrected serum concentration, and standardized serum concentration. Results: The total dose of CBZ and the dose of CBZ/kg body weight was higher in the CYP3A5 expressor group than the non-expressor (P = 0.043 and P = 0.014, respectively). The dose-corrected and standardized serum concentrations were lower in the CYP3A5 expressor group than the non-expressor (P = 0.001 and P < 0.001, respectively). There was however, no signifi cant difference in serum drug concentration between the two groups (P = 0.487). Conclusions: There was a close relationship between CYP3A5 genetic polymorphism and the serum concentrations of carbamazepine.
