  • Retrospective analysis of risk factors in 116 patients with nonarteritic anterior ischemic optic neuropathy

    ObjectiveTo analyze retrospectively the risk factors of nonarteritic anterior ischemic optic neuropathy (NAION). MethodsThe complete clinical data of 116 patients (134 eyes) were collected. All patients were asked in detail about the disease history and symptoms and were examined for the visual acuity, intraocular pressure, fundus, visual field and fundus fluorescein angiography (FFA), blood pressure, blood glucose, blood fat and head MRI or CT. Suspicious cases and patients with incomplete clinical data were excluded. The relationship between NAION and age, visual field, FFA, systemic and ocular factors, onset seasons were retrospectively analyzed. Results80 patients (68.97%) were 55 to 70 years old. 97 patients (83.7%) had systemic diseases, including 38 patients (39.2) with diabetes mellitus, 32 patients (32.9%) with hypertension (8 patients had low blood pressure at night), 28 patients (28.9%) with hyperlipidemia, 16 patients (16.5%) with cerebrovascular diseases (mainly lacunar cerebral infarction), 6 patients (6.2%) with coronary heart disease. There were 8 patients with ocular factors, including 3 patients (2.6%) with cataract surgery history, 5 patients (4.2%) with small optic discs. The difference of percentage of with or without diabetes mellitus and hypertension was significant (χ2=362, 259; P < 0.05). There were 27.6% patients with disease onset at March to April, 24.1% patients with disease onset at September to October, much higher than other months (χ2=580, P < 0.05). Visual field test results showed that 49 eyes (36.5%) had inferior visual field defect, 12 eyes (9.0%) had superior visual field defect. FFA showed that in the early stage 103 eyes (76.9%) had optic weak fluorescence, 13 eyes (9.7%) had strong fluorescence; in the late stage, 110 eyes (82.1%) had strong fluorescence, 8 eyes (6.0%) had weak fluorescence. ConclusionsDiabetes mellitus, hypertension may be the system risk factors of NAION. The seasonal variation from spring to summer and from autumn to winter may also be another risk factor for the onset of NAION.

  • A case control study on risk factors in central retinal vein occlusion

    Objective To investigate the relationship among central retinal vein occlusion (CRVO), major systemic diseases, ocular local diseases and related risk factors in Chinese population. Methods Seventeen-six patients with CRVO diagnosed by fundus fluorescein angiography (FFA) without any medical treatment were in CRVO group. Another 76 patients without CRVO or any vascular diseases of ocular fundus were in the control group who were matched with the ones in CRVO group to a one-to-one partnership according to the age and gender. The 2 groups were subdivided into le;45 years old (25 patients, 32.9%) and gt;45 years old (51 patients, 67.1%) subgroups according to the age, and 2 ischemia and non-ischema subgroups according to the results of FFA, respectively. The blood lipid, blood pressure, and fasting blood glucose were measured. The systematic diseases, ocular local diseases and the related risk factors were statistically analyzed and compared. Results The incidence of hypertension and hyperlipemia in CRVO group were significantly higher than that in the control group (Plt;0.001,P=0.001). There was no significant difference of cardiovascular diseases, cerebrovascular diseases, open-angle glaucoma, and smoking and drinking between the two groups(Pgt;0.05). In le;45 years old subgroups, there was no significant difference of each examination target between CRVO and control group(Pgt;0.05). In ischemia subgroups, except for the hypertension and hyperlipemia, the incidence of diabetes mellitus was obviously higher in CRVO group than that in the control group (hyperlipidemia:P=0.031; diabetes mellitus:P=0.024; diabetes mellitus: Plt;0.001). Conclusion Hypertension and hyperlipidemia are the systematic factors in Chinese population with occurrence of CRVO. In addition, diabetes mellitus is associated with ischemic CRVO. Timely diagnosis and treatment of the systematic diseases is important to the prevention and treatment for CRVO. (Chin J Ocul Fundus Dis, 2007, 23:159-162)

  • Investigation and Analysis on the Nosocomial Infection in 1 621 Hospitalized Patients with Acute and Serious Schizophrenia

    ObjectiveTo investigate the incidence of nosocomial infection in acute and serious schizophrenic inpatients and its risk factors. MethodsBetween January 1st and December 31st, 2012, we investigated 1 621 schizophrenic patients on the status of nosocomial infections according to the hospital standard of nosocomial infection diagnosis. They were divided into infected group and uninfected group according to the survey results. The risk factors were analyzed by logistic regression method. ResultsTwenty-nine infected patients were found among the 1 621 patients, and the incidence rate was 1.79%. Among the nosocomial infections, the most common one was respiratory infection (79.31%), followed by gastrointestinal infection and urinary infection (6.90%). There were significant differences between the two groups of patients in age, hospital stay, positive and negative syndrome scale (PASS), combined somatopathy, the time of protective constraint, modified electraconvulsive therapy (MECT), using two or more antipsychotics drugs, using antibiotics and side effects of drugs (P<0.05). However, there were no statistical differences in gender, age classes, the course of disease, frequency of hospitalization and seasonal incidence of hospital infection (P>0.05). The results of multivariate analysis showed that hospital stay, positive symptom score, negative symptom score, the time of protective constraint, MECT, using two or more antipsychotics drugs and side effects of drugs were the main risk factors for nosocomial infection of inpatients with psychopathy (P<0.05). ConclusionBased on the different traits and treatments of acute and serious schizophrenia, a screening table of infections should be set. For the high risk group of nosocomial infection, effective measures should be taken to prevent and control the nosocomial infection of patients with schizophrenia.

  • Risk factors and optical coherence tomography characteristics of exudative retinal detachment in patients with HELLP syndrome

    ObjectiveTo observe and analyze the risk factors and optical coherence tomography (OCT) characteristics of exudative retinal detachment in patients with HELLP syndrome. MethodsA retrospective clinical study. From January 2015 to March 2021, 168 eyes of 84 patients with HELLP syndrome who were hospitalized in The Third Central Hospital of Tianjin were included in the study. The average age of the patients was 30.96±4.09 years old. The patient’s general clinical data which included age, gestational week of delivery, type of HELLP syndrome, onset time of HELLP syndrome, parity, number of pregnancy, systolic and diastolic blood pressure, total amount and duration of glucocorticoid, whether been admitted to intensive care unit; laboratory indicators, which included platelet count,serum albumin, serum uric acid, 24-hour urine protein quantification,aspartate aminotransferase, lactate dehydrogenase, total bilirubin (TBIL) were collected. Whose the general condition was not allowed, however patients had a complaint of vision loss or suspected retinal detachment under direct ophthalmoscope examination, B-mode ultrasound was used to assist in the diagnosis. According to the presence or absence of exudative retinal detachment, patients were divided into retinal detachment group (net detachment group) and non-retinal detachment group (non-retinal detachment group), respectively 31 (36.90%, 31/84), 53 (63.10%, 53/84) cases. Among the 31 cases in the network disconnection group, 34 eyes in 17 cases underwent OCT. Two independent sample t tests were used to compare the measurement data of normal distribution between groups, Wilcoxon rank sum test was used to compare skewed distributions; the χ2 test was used to compare count data. The variables with statistical differences in univariate analysis were selected as independent variables, and binary logistic regression analysis was performed. ResultsAmong 84 patients, HELLP syndrome was classified into partial type and complete type, 41 (48.81%, 41/84) and 43 (51.19%, 43/84) cases, respectively. Compared with the non-net-off group, the patients in the off-line group had shorter gestational weeks (t=2.51), higher diastolic blood pressure (t=−2.61), greater total glucocorticoid use (Z=−2.14), and longer use time of glucocorticoid (Z=−2.75), the difference were statistically significant (P<0.05); TBIL (Z=−2.49), serum albumin (t=2.06) levels decreased, and 24-hour urine protein quantitative (Z=−4.35) levels increased, the difference were statistically significant (P<0.05). Logistic regression analysis showed that the increase of 24-hour urine protein level increased the risk of exudative retinal detachment (P<0.05) (odds ratio=1.20, 95% confidence interval 1.06-1.37). Among the 34 eyes that underwent OCT examination, 18 eyes showed that the retinal pigment epithelium (RPE) layer was not smooth, thickened, and seemed to have adhesion to the detached retina. After the reattachment of retinal detachment, the above-mentioned changes of RPE still existed, but reduced; the ellipsoid zone still has discontinuity, partial rupture, and even extensive loss in 16 eyes. ConclusionThe quantitative increase of 24-hour urine protein is a risk factor for the occurrence of exudative retinal detachment in HELLP syndrome; some patients with exudative retinal detachment are still missing the ellipsoid zone after reattachment.

  • Risk factors analysis and prediction model construction of self-limited epilepsy with centrotemporal spikes compilcated by electrical status epilepticus during sleep

    ObjectiveTo analyze the risk factors for electrical status epilepticus during sleep (ESES) in patients with self-limited epilepsy with centrotemporal spikes (SeLECTs) and to construct a nomogram model. MethodsThis study selected 174 children with SeLECTs who visited the Third Affiliated Hospital of Zhengzhou University from March 2017 to March 2024 and had complete case data as the research subjects. According to the results of video electroencephalogram monitoring during the course of the disease, the children were divided into non-ESES group (88 cases) and ESES group (86 cases). Multivariate logistic regression analysis was used to identify the risk factors for the occurrence of ESES in SeLECTs patients. ResultsThe multifactor Logistic regression analysis demonstrated that the EEG discharges in bilateral cerebral areas,types of seizure, epileptic seizures after initial treatment were the independent risk factors for the occurrence of ESES in SeLECTs. ConclusionBilateral distribution of electroencephalogram discharges before treatment, emergence of new seizure forms, and epileptic seizures after initial treatment are risk factors for the ESES in SeLECTs patients. The nomogram model constructed based on the above risk factors has a high degree of accuracy.

  • Risk Factors for Mortality in the Arterial Switch Operation

    Abstract: Objective To analyze risk factors for perioperative mortality in the arterial switch operation (ASO), in order to provide better operation and decrease the mortality rate. Methods We enrolled 208 ASO patients including 157 males and 51 females at Fu Wai Hospital between January 1, 2001 and December 31, 2007. The age ranged from 6 h to 17 years with the median age of 90 d and the weight ranged from 3 kg to 43 kg with the median weight of 5 kg. Among the patients, 127 had transposition of great artery (TGA) with ventricular septal defect (VSD), and 81 patients had TGA with intact ventricular septum (IVS) or with the diameter of VSD smaller than 5 mm. Coronary anatomy was normal (1LCX2R) in 151 patients and abnormal in the rest including 15 patients with single coronary artery, 6 with intramural and 36 with inverse coronary artery. Preoperative, perioperative and postoperative clinical data of all patients were collected to establish a database which was then analyzed by univariate analysis and multivariate logistic regression analysis to find out the risk factors formortality in ASO. Results There were 24 perioperative deaths (11.54%) in which 12 died of postoperative infection with multiple organ failure (MOF), 10 died of low cardiac output syndrome, 1 died of pulmonary hypertension, and 1 died of cerebral complications. Among them, 20 patients (18.30%) died in early years from 2001 to 2005, while only 4 (4.00%) died in the time period from 2006 to 2007, which was a significant decrease compared with the former period (Plt;0.05). The univariate analysis revealed that cardiopulmonary bypass (CPB) time was significantly longer in the death group than in the survival group(236±93 min vs. 198±50 min, P=0.002), and occurrence of major coronary events (33.3% vs. 2.2%, P=0.000) and unusual coronary artery patterns(33.3% vs. 6.5%,P=0.000) were much more in the death group than in the survival group. Multivariate logistic regression analysis showed that early year of [CM(159mm]operation (OR=7.463, P=0.003), unusual coronary artery patterns (OR=6.303,P=0.005) and occurrence of majorcoronary events (OR=17.312, P=0.000) were independent predictors for perioperative mortality. Conclusion The ASO can be performed with low perioperative mortality in our hospital currently. Occurrence of major coronary events, unusual coronary artery patterns and year of surgery before 2006 are independent predictors for perioperative mortality.

  • Risk Evaluation of Colorectal Cancer Patients with Neo-Adjuvant Chemotherapy Combined with Operation in Multi-Disciplinary Team

    Objective To evaluate the risk of management decision combined neo-adjuvant chemotherapy with operation for colorectal cancer by means of the colorectal cancer model of the Association of Coloproctology of Great Britain and Ireland (ACPGBI-CCM). Methods One hundred and eighty-one eligible patients (102 male, 79 female, mean age 58.78 years), which were pathologically proved colorectal cancer in our ward from July to November 2007, involved 62 colonic and 119 rectal cancer. The enrollment were assigned into multi-disciplinary team (MDT) group (n=65) or non-MDT group (n=116), according to whether the MDT was adopted, and the operative risk was analyzed by ACPGBI-CCM. Results The baseline characteristics of MDT and non-MDT group were coherent. The watershed of lower risk group (LRG) and higher risk group (HRG) was set as predictive mortality=2.07%. The time involving extraction of gastric, urethral and drainage tube, feeding, out-of-bed activity after operation in MDT group, whatever in LRG or HRG, were statistically earlier than those in non-MDT group (P<0.05). The resectable rate in LRG was statistically higher than that in HRG (P<0.05), and the proportion of Dukes staging was significantly different (P<0.05) between two groups; Moreover, predictive mortality in HRG was statistically higher than that in LRG (P<0.05), while actually there was no death in both groups. Conclusion Dukes staging which is included as an indispensable option by ACPGBI-CCM is responsible for the lower predictive mortality in LRG.Hence, the value of ACPGBI-CCM used to asses the morbidity of complications within 30 days postoperatively would be warranted by further research. The postoperative risk evaluation can serve as a novel routine to comprehensively analyze the short-term safe in the MDT.

  • Ischemic Stroke during Low Intensity Anticoagulation Therapy after Mechanical Heart Valve Replacement

    Objective To investigate the risk factors and the prevention and cure methods of ischemic stroke during low intensity anticoagulation therapy after mechanical heart valve replacement. Methods From March 2004 to July 2008,twentythree patients with ischemic stroke after mechanical heart valve replacement had been researched(ischemic stroke group). One hundred and twenty patients who had undergone mechanical heart valve replacement were randomly chosen in the same period as control group. Gender, age, the dose of warfarin , anticoagulation intensity(INR), INR review interval, left atrial diameter and heart rhythm were compared between the two groups, and the risk factors of ischemic stroke were analyzed by logistic regression analysis. Results (1) Patients in ischemic stroke group all discharged from hospital after treatment, and they were followed up for 1 month-3 years after discharged. All the patients’ neurological complications improved obviously, and no recurrent embolism and severe hemorrhage was found. (2) There was no statistical significance between two groups in gender, age and the dose of warfarin(Pgt;0.05). (3) Nonconditional logistic regression analysis on influence factors showed that atrial fibrillation(P=0.000), left atrial enlargement(P=0.002), low anticoagulation intensity(P=0.012) and longtime INR review interval(P=0.047)were the risk factors of ischemic stroke during low intensity anticoagulation therapy after mechanical heart valve replacement. Conclusions (1)The prognosis of ischemic stroke during low intensity anticoagulation therapy after mechanical heart valve replacement is better than that of intracranial hemorrhage, and the occurrence of ischemic stroke is related to many risk factors. (2)The influences of risk factors should be minimized in order to avoid ischemic stroke. (3) Early low intensity anticoagulation therapy is safe and effective for patients with ischemic stroke after heart valve replacement.
