ABSTRACT
In recent years, the incidence of high myopia complicated with cataract shows a gradual upward trend. Due to the special anatomical structure and lesion nature of high myopia, the difficulty and various complications of such patients are much higher than those of ordinary cataract surgery. With the continuous advancement of design and materials, the indications for capsular tension ring(CTR)have gradually expanded. Especially for patients with high myopia,it can maintain the stability of intraocular lens position, assist the relaxation of the suspensory ligament, inhibit the migration and proliferation of residual lens epithelial cells after surgery, improve the visual quality of patients and reduce the incidence of retinal detachment. This paper reviewed the history of CTR, its clinical application, and the effect of CTR on high myopia complicated with cataract.
ABSTRACT
Objective To verify the relationship between catheter-related urinary tract infection(CAUTI)and stress hyperglycemia during catheter retention in stroke patients. Methods We used nosocomial infection monitoring system to track the status of CAUTI in stroke patients in a hospital.The study cohort was all the patients who received retention catheterization from January 2016 to March 2020.According to the nested case-control design,multivariate logistic regression analysis was performed to explore the relationship between stress hyperglycemia and CAUTI in stroke patients with indwelling catheter. Results A total of 322 cases of CAUTI and 644 cases of non-CAUTI were enrolled in this study.The length of stay in the case group was(20.68 ± 3.73)d,significantly longer than that[(13.00 ± 4.01)d]in the control group(t=29.473,P <0.001).Compared with non-stress hyperglycemia,stress hyperglycemia posed a higher risk of CAUTI in the stroke patients with indwelling catheter(OR=2.020,95% CI=1.447-2.821,P=0.000)and led to the higher incidence of CAUTI in one thousand days(P<0.001). Conclusion Stress hyperglycemia in the stroke patients with indwelling catheter can significantly increase the risk of CAUTI.
