ObjectiveTo investigate the related factors of the retina1 hemorrhage in newborns. Methods9558 newborns included in this observation between March of 2012 and July of 2013 in our hospital. The fundus was examined by the fully-integrated wide-field digital imaging system RetCamⅢat 0-4 days after born. According to the literature, retinal hemorrhage was classified into degreeⅠ, ⅡandⅢ. The condition for baby and the mother during pregnancy were correlatively analyzed. The other factors were analyzed including twins, premature delivery, big baby, mode of delivery, fetal birth, forceps delivery, suction delivery, asphyxia, jaundice, ABO hemolytic, cranial hematoma, intracranial hemorrhage, maternal age, first-time mom, the maternal previous mode of production, emergency delivery, the first stage of labor prolonged, the second stage of labor prolonged, the third stage of labor prolonged, pregnancy-induced hypertension, gestational diabetes, oxytocin, prenatal body mass index (BMI). Multivariate logistic regression analysis was used. ResultsIn 9558 cases of newborns, retinal hemorrhages were found in 2753 infants (28.8%), including 1137 degreeⅠ(41.3%), 895 degreeⅡ(32.5%) and 721 degreeⅢ(26.2%). Multivariate logistic regression analysis showed that the mode of delivery, asphyxia, jaundice, advanced maternal age, maternal previous birth, prenatal BMI is a risk factor for neonatal values retinal hemorrhage (r=0.146, 5.841, 1.847, 0.071, 0.246, 0.965;P < 0.05). The degree of fundus hemorrhage was not related to birth weight and BMI (P > 0.05). ConclusionsThe neonatal retinal hemorrhage rate was 28.8%. Mode of delivery, asphyxia, neonatal jaundice, maternal age, the previous mode of delivery of mothers with more than one previous birth, prenatal BMI values may be risk factors lead to retinal hemorrhage.
Objective To investigate the prevalence and related factors of diabetic retinopathy (DR) among residents with type 2 diabetes mellitus (T2DM) in Culai Town of Tai'an City in Shandong Province. Methods According to the DM management file database for community, 785 patients with T2DM were randomly selected by cluster sampling method. The questionnaires, routine general examinations, visual and fundus-free fluoroscopy were performed on all the patients. DR diagnosis and classification was according to the guidelines for clinical diagnosis and treatment of DR in China (2014). Both monocular and binocular DR were selected as DR patients, and the worse eye for binocular DR were treated as the DR classification of the patient. The patients were grouped by presence or absence of DR. GraphPad Prism 6, SigmaPlot 12.5, SPSS 20.0 and Excel were used to achieve data analysis. Also, SPSS 20.0 was used for multi-factor logistic regression analysis. Results A total of 699 patients (89.04%) were actually recorded. There were 122 eyes of 63 patients (9.01%) with DR (DR group), 1272 eyes of 636 patients (90.99%) without DR (NDR group). Among the 122 eyes of DR, there were 19 (15.57%), 17 (13.93%), 70 (57.38%), 10 (8.20%), 6 (4.92%) eyes in stage Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ, respectively. The differences of mean age (t=15 290, P=0.002), DM duration (t=9075, P＜0.000) and diastolic blood pressure (t=15 810, P=0.006) between the two groups were statistically significant. There were 23 (36.51%) and 394 (61.95%) patients with hypertension history in the DR group and the NDR group, with the significant difference ( χ2=15.42, OR=0.35, 95%CI 0.21-0.60). There were 57 (90.48%) and 500 (78.62%) patients with fasting blood glucose larger than 6.11 mmol/L in the DR group and the NDR group, with the significant difference (OR=2.51, 95%CI 1.06-5.95, P=0.031). Logistic regression analysis showed that the age, fasting blood glucose and DM duration were influencing factors for DR (OR=1.039, 0.864, 0.898; P=0.021, ＜0.000, ＜0.000). Conclusion The prevalence of DR in patients with T2DM in Culai Town of Tai'an City is 9.01%. Age, DM duration, fasting blood glucose are associated to DR. Those with a history of hypertension may have a lower risk of DR than those without a history of hypertension.
ObjectiveTo observe and preliminary investigate the influencing factors of exudative retinal detachment in patients with severe preeclampsia (S-PE) and its influence on pregnancy outcome.MethodsA total of 89 patients of S-PE patients diagnosed in Department of Obstetrics in The Third Central Hospital of Tianjin from July 2018 to June 2020 were included in this study. According to whether the patients were complicated with exudative retinal detachment, they were divided into retinal detachment group (43 cases) and non retinal detachment group (46 cases). All patients underwent direct ophthalmoscopy, and those with suspected or definite retinal detachment underwent optical coherence tomography or B-mode ultrasonography. The age, course of disease, body mass index, systolic blood pressure, diastolic blood pressure, laboratory serum albumin level, 24 h urinary protein, platelet count, mean platelet volume, platelet distribution width and serum uric acid content were collected. The average age (t=−1.01), body mass index (t=−1.799), course of disease (t=−1.657) and constituent ratio of primipara and multipara in the two groups were compared (χ2=1.411), the difference was not statistically significant (P＞0.05). The end of pregnancy time, systemic complications, fetal outcomes and neonatal Apgar scores were analyzed, retrospectively. Independent sample t test was used to compare the quantitative data between the two groups; Chi square test was used to compare qualitative data. Binary logistic regression analysis to screen the influencing factors of exudative retinal detachment in S-PE.ResultsSystolic blood pressure and diastolic blood pressure were higher in the retinal detachment group than in the non retinal detachment group, and the difference was statistically significant (t=2.087, 2.810; P=0.040, 0.006). Serum albumin (t=−10.404), 24-hour urinary protein quantification (t=6.401), blood uric acid (t=3.910), platelet count (t=−6.124) and platelet distribution width (t=2.992) were compared between the two groups, and the differences were statistically significant (P＜0.05). There were 30 (69.77%, 30/43) cases in retinal detachment group and 14 (30.43%, 14/46) cases in non retinal detachment group with severe systemic complications; The average time of ending pregnancy was 34.66±3.29 and 38.25±1.62 weeks; The average Apgar scores at birth were 7.28±3.40 and 9.46±1.59. The incidence of severe systemic complications in two groups (χ2=13.755), the end of pregnancy time (t=−6.448), Apgar score at birth (t=−3.824), the differences were statistically significant (P=0.000、0.000、0.000). Fetal distress and death were 8 (18.60%, 8/43), 7 (16.28%, 7/43) and 7 (15.22%, 7/46), 1 (2.17%, 1/46) in retinal detachment group and non retinal detachment group respectively. There was no significant difference in the incidence of fetal distress between the two groups (χ2=0.182, P=0.670). The difference of fetal mortality was statistically significant (P= 0.027). Logistic regression analysis showed that serum albumin and uric acid were associated with exudative retinal detachment in patients with S-PE (P＜0.05).ConclusionsSerum albumin and uric acid are the influencing factors of exudative retinal detachment in patients with S-PE. Patients with exudative retinal detachment are prone to adverse pregnancy outcomes.
Objective To investigate the risk factors associated with neovascular glaucoma (NVG) after pars plana vitrectomy (PPV) in eyes with proliferative diabetic retinopathy (PDR). Methods Retrospective study. One hundred and thirty-seven patients (137 eyes) with PDR who underwent PPV were recruited. There were 85 males and 52 females. The average age was (60.1±8.8) years old. The duration of diabetes was (10.2±3.6) years. There were 49 patients with ipsilateral carotid artery stenosis. Fifty-three eyes underwent intravitreal ranibizumab or conbercept injection before PPV. All eyes were treated with 23G standard three-port PPV. The average follow-up time after PPV was 11.5 months. Fundus fluorescein angiography (FFA) was conducted in postoperative 4-6 weeks to observe non-perfused retinal areas. Risk factors, such as ipsilateral carotid artery stenosis, the presence of non-perfusion in retina after PPV and the application of anti-vascular endothelial growth factor (VEGF) drugs before PPV, were identified by logistic regression. Results Twenty of 137 patients (14.6%) developed postoperative NVG after PPV. Ipsilateral carotid artery stenosis [odds ratio (OR) =5.048, 95% confidence interval (CI) 2.057-12.389,P=0.000] and the presence of non-perfusion in retina after PPV (OR=4.274, 95%CI 1.426-12.809,P=0.009) were significant risk factors for postoperative NVG, while the application of anti-VEGF drugs was not (OR=1.426, 95%CI 0.463-4.395,P=0.536). But the time from PPV to the onset of NVG varies significantly between the two groups of injection of anti-VEGF drugs or not (t=−4.370,P=0.000). Conclusions Risk factors associated with NVG after PPV in eyes with PDR included ipsilateral carotid artery stenosis and the presence of non-perfusion in retina after PPV. The application of anti-VEGF drugs before PPV can delay the onset of NVG in PDR eyes after vitrectomy.
ObjectiveIn order to provide guidance for early interference of diabetic retinopathy (DR) in patients with diabetes mellitus (DM), we surveyed the prevalence and analysis the related factors of DR in Shanghai Songnan community. MethodsBased on an established resident health database, an epidemiology study was performed on the residents with DM in Shanghai Songnan community.1177 patients completed questionnaire survey, and received physical examination and laboratory tests. The diagnosis and grading of DR were established based on the ocular fundus images acquired by digital non-mydriasis fundus camera. Patients with incomplete questionnaires were excluded. ResultsThere were 1120 DM patients with valid questionnaires. DR was found in 264 (23.57%) patients. The prevalence of mild, moderate, severe non-proliferative DR and proliferative DR was 17.05%, 5.09%, 1.16% and 0.27% respectively. There was significant differences in age, disease course, systolic blood pressure, insulin usage between the DR group and NDR group(t=-2.647, 2.688, 2.204, 2.291;χ2=12.527;P=0.008, 0.007, 0.028, 0.022, 0.000). There was significant differences in fasting blood-glucose and insulin usage between the mild, the moderate and the severe DR group(t=21.964, χ2=14.996;P=0.000, 0.001). Stepwise logistic analysis identified that age, DM course, and insulin usage were the related factors of DR (OR=0.769, 1.239, 1.100, 1.071, 1.682;P=0.001, 0.043, 0.176, 0.097, 0.005). ConclusionThe age, DM course, and insulin usage were the related factors of DR. The high prevalence of DR indicated the importance of the management of diabetic patients.
ObjectiveTo investigate the factors correlated with the visual outcome of idiopathic macular holes (IMH) after vitreoretinal surgery. MethodsA total of 57 eyes of 57 patients with IMH were included. There were 43 females (43 eyes) and 14 male (14 eyes), mean age was (60.46±4.79) years. All the eyes underwent best corrected visual acuity (BCVA), slit-lamp microscope, three-mirror contact-lens and optical coherence tomography (OCT) examinations. BCVA were examined with interactional visual chart and recorded with logarithm of the minimum angle of resolution (logMAR) acuity. The minimum diameter and base diameter of macular holes and central retinal thickness (CRT) were detected by OCT. The average logMAR BCVA of 57 eyes was 0.98±0.41. The minimum diameter and base diameter of macular holes were (479.53±164.16) μm and (909.14±278.65) μm. All the patients underwent pars plana vitrectomy combined with phacoemulsification cataract extraction and intraocular lens implantation. The mean follow-up period was (173.44±147.46) months. The relationships between final BCVA and these parameters were examined by single and multiple regression analysis. The valuable influence factors were filtrated and formulated using multiple linear regression models. ResultsAt the final follow-up, the logMAR BCVA of 57 eyes was 0.44±0.31, the CRT was (158.79±86.96) μm. The final BCVA was positive related to minimum diameter of macular holes and preoperative BCVA (r=0.420, 0.448; P=0.001, 0.000), negative related to postoperative CRT (r=-0.371, P=0.004). There was no relationship between the final BCVA and base diameter of macular holes, age and follow-up (r=0.203, -0.015, 0.000; P=0.130, 0.913, 0.999). The incidence of preoperative BCVA for postoperative BCVA was bigger than preoperative minimum diameter of macular holes (P=0.008, 0.020). ConclusionThe preoperative minimum diameter of macular holes and BCVA are related to postoperative BCVA in IMH eyes.
Objective To analyze the death cause of residents in Zigong from 1985 to 2009, so as to provide the government with scientific information of health strategies, and disease prevention and control. Methods The death surveillance data in Zigong residents from 1985 to 2009 were collected, and the indexes such as all death mortality rate, infant mortality rate, maternal mortality rate, disease-specific mortality rate, age-specific mortality rate, and life expectancy were analyzed. Results The all death mortality rate had fluctuation of plus or minus 6‰, and the male mortality rate was higher than the female (χ2=8 059.769, P=0.000). The six main influencing factors of the death of Zigong residents were as follows: respiratory system diseases, circulatory system diseases, tumour, injury and poisoning regarded as external cause diseases, digestive system diseases, and infectious diseases and parasitic diseases. The mortality rates of different districts were statistically different (χ2=1 643.926, P=0.000), and Fushun County was the highest among them after standardization. The curve of mortality rate in different sex and age groups was changed alike letter “U”. The mortality rate was ascending with the age in the group of over 15 years old, the ascending trend was more evident especially after 50 years old. The infant mortality declined steadily and was well controlled. The maternal mortality declined obviously. The average life expectancy for the whole city was 74.72, which showed an ascending trend. Conclusion The chronic diseases are the main death cause of residents in Zigong. The prevention and controlling of acute infectious diseases and parasitic diseases should be persistently performed for declining both incidence rate and mortality rate. The Zigong city is gradually stepping into aging society, which requires the great development of senior work.
ObjectiveTo explore the application and effect of root cause analysis (RCA) in the management of adverse nursing events. MethodsNursing staff members were trained to establish the team of root cause analysis. They collected related materials of adverse nursing events in the infusion room of the Department of Pediatrics, found out the proximal causes and root causes, developed and implemented the corrective measures. RCA was carried out between January 2013 and December 2014. The efficacy was evaluated and the adverse events rate was compared before and after the practice. ResultsAfter the performance of RCA, the reporting rate of adverse events increased, the rate of adverse events decreased, and the reporting rate of potential safety problems also increased. All those changes were significant (P<0.01). ConclusionRoot cause analysis can decrease the rate of adverse nursing events, raise the reporting rate of adverse events. It is an effective guarantee to improve the nursing safety management.
ObjectiveTo observe and analyze the risk factors related to vitreous re-hemorrhage (PVH) after anti-VEGF drugs combined with vitrectomy (PPV) in patients with proliferative diabetic retinopathy (PDR).MethodsRetrospective analysis study. From April 2017 to July 2018, 100 eyes of 87 PDR patients who were diagnosed in Jiaxing Eye Hospital and received anti-VEGF drugs combined with 25G PPV were included in the study. Among them, there were 44 eyes in 38 males and 56 eyes in 49 females. The age ranged from 26 to 83 years, with an average age of 57.72±8.82 years. All patients were type 2 diabetes, with an average duration of diabetes 10.84±6.03 years. All affected eyes were assisted by the same doctor with a non-contact wide-angle lens under the standard three-channel 25G PPV of the flat part of the ciliary body. Five to 7 days before the operation, intravitreal injection of ranibizumab or conbercept 0.05 ml (10 mg/ml) was performed. The incidence of PVH was observed. The age of PVH patients, duration of diabetes, vision before operation, average fasting blood glucose and average postprandial blood glucose before operation, systolic blood pressure and diastolic blood pressure before surgery, laser treatment before surgery, lens removal during operation, intraocular filling during operation, retinal laser points during operation, and fundus lesions during operation (hyperplasia film, Retinal hemorrhage, vascular occlusion, proliferative retinal traction, retinal hiatus, retinal detachment, exudation, neovascularization) were analyzed to find out the cause of PVH. Spearman bivariate correlation analysis and binary logistic regression analysis were performed on the data.ResultsOf the 100 eyes of 87 patients, PVH occurred in 17 eyes (17%). There were statistically significant differences in the number of eyes with vascular occlusion and proliferative traction during surgery in patients with and without PVH (χ2=5.741, 8.103; P＜0.05). There was no significant difference in age (t=－1.364), duration of diabetes (t=0.538), preoperative vision (t=1.897), preoperative fasting blood glucose level (t=1.938), preoperative postprandial blood glucose level (t=1.508), preoperative systolic blood pressure (t=－0.571), preoperative diastolic blood pressure (t=0.275), whether received laser treatment (χ2=2.678), the number of laser points during operation (t=0.565), whether received lens removal during operation (χ2=0.331), whether found new blood vessels during operation (χ2=2.741) and whether received intraocular filling during operation (χ2=0.060) between the patients with and without PVH (P＞0.05). Spearman's bivariate correlation analysis showed that patients with low vision, poor control of fasting blood glucose levels, vascular occlusion and proliferative retinal traction during the operation were related risk factors for PVH (rs=0.208, 0.229, 0.240, 0.285; P＜0.05). Binary logistic regression analysis showed that fundus vascular occlusion and hyperplastic retinal traction may be independent risk factors for PVH during surgery (OR=5.175, 13.915; P＜0.05).ConclusionFundus vascular occlusion and retinal traction caused by fibrovascular membrane hyperplasia in PPV may be independent risk factors for PVH in patients with PDR after anti-VEGF drugs combined with PPV.
ObjectiveTo analyze the status and influencing factors of awareness of diabetic retinopathy (DR) knowledge in diabetics in Funing County, Jiangsu Province. MethodsThis is a cross-sectional study. In 2021, a total of 2 125 residents with diabetes in Funing County, Jiangsu Province were recruited using cluster random sampling methods. General examinations were performed and ophthalmological evaluation were conducted including visual acuity in daily life, slit lamp microscope with preset lens, digital non-mydriatic fundus photography. Clinical assessment and classification of DR were according to the international standard clinical classifications of diabetic retinopathy in 2019. DR was classified into no obvious DR, mild non-proliferative diabetic retinopathy (NPDR), moderate NPDR, severe NPDR and proliferative diabetic retinopathy (PDR). Field questionnaire surveys were conducted to show the awareness rate of DR knowledge. Then Chi-square test and Logistic regression analysis were used to investigate influencing factors. ResultsAmong 2 125 subjects, 762 (35.86%, 762/2 125) residents were male and 1 363 (64.14%, 1 363/2 125) residents were female. A total of 444 (20.89%, 444/2 125) subjects were diagnosed as DR. Among which, 438 (20.61%, 438/2 125) subjects were NPDR, 6 (0.28%, 6/2 125) subjects were PDR. A total of 419 (19.72%, 419/2 125) subjects were diagnosed as cataract. The topic awareness rates were all below 45.00%. The overall population awareness rate was 19.45% (4 959/25 500). Awareness rate was correlated with age, visual acuity in daily life, education level, family history of diabetes, diabetic retinopathy grades and the type of treatment for diabetes (P＜0.001). Logistic regression analysis showed that the knowledge rate of prevention and treatment of DR Decreased significantly in patients aged 60-79 compared with those aged under 50 (P＜0.05). Compared with those with visual acuity＜0.1 in daily life, the knowledge rate of DR prevention and treatment in those with visual acuity≥0.1 was significantly decreased (P＜0.05). While primary school to college education, with family history of diabetes, with DR, oral hypoglycemic agents and/or insulin treatment were associated with higher awareness rate (P＜0.05). ConclusionsThe DR knowledge level is low among diabetics in Funing County, Jiangsu Province in 2021. Age, visual acuity in daily life, education level, family history of diabetes, with DR and receiving drug treatments are main influencing factors for diabetic’s awareness.
