AbstractWhile the precise diagnosis of early stage epiretinal membrane (ERM) at the time of cataract surgery and evaluation of risk factors for development or progression of ERM after cataract surgery is increasingly important, there is only limited information. In the present study, we evaluated the risk factors for onset or progression of ERM on spectral domain optical coherence tomography (SD-OCT) after cataract surgery. The univariate analysis showed that eyes with partial posterior vitreous detachment (PVD; p < 0.001), hyper-reflective foci (HF) on the inner retinal surface (p < 0.001), vitreoschisis (p = 0.014), and discrete margin of different retinal reflectivity (DMDRR; p = 0.007) on ultra-widefield fundus photography (UWF-FP) had significant risk for the onset or progression of ERM after cataract surgery. The multivariate analysis showed that partial PVD (HR, 3.743; 95% confidence interval [CI], 1.956–7.162; p < 0.001), HF (HR, 2.330; 95% CI, 1.281–4.239; p = 0.006), and DMDRR on UWF-FP (HR, 3.392; 95% CI, 1.522–7.558; p = 0.003) were the independent risk factors for the onset or progression of ERM after cataract surgery after adjustment for other confounding factors. Our study shows that the onset or progression of ERM after cataract surgery depends on an abnormal vitreoretinal interface (VRI) represented by partial PVD, HF on SD-OCT, and DMDRR on UWF-FP, not on age, axial length, or presence of ERM at the time of surgery. A meticulous funduscopic evaluation of the VRI would help to predict the ERM risk before cataract surgery.

Purpose: To investigate the incidence and risk factors of epiretinal membrane (ERM) after cataract surgery.Methods: We reviewed the medical records of patients who underwent cataract surgery between January 2016 and December 2018. Eyes with ERM, as observed by optical coherence tomography performed 1-2 months after surgery, were excluded from the study. ERM was diagnosed by fundus photography. The incidence rate was determined 2-6, 6-12, and 12-24 months after surgery. The cumulative incidence rate of ERM was calculated by Kaplan-Meier analysis. Data were analyzed using logistic regression to determine the associations between ERM development and various factors.Results: The study included 218 eyes of 161 patients with a mean age of 66.6 ± 9.7 years at the time of surgery. ERM was observed in 3 of 218 eyes (1.4%) between 2 and 6 months, 15 of 176 eyes (8.3%) between 6 and 12 months, and 14 of 150 eyes (10.3%) between 12 and 24 months after surgery. The cumulative incidence rate of ERM was 11.7% over the 24-month period after surgery. In multivariate logistic regression analysis, older age (≥65 years; odds ratio [OR], 8.59, 95% confidence interval [CI], 1.43-51.49), fellow eye with ERM (OR, 3.63; 95% CI, 1.04-12.73), longer axial length (≥26 mm; OR, 8.02; 95% CI, 1.08-59.66), and complete posterior vitreous detachment development (OR, 7.48; 95% CI, 1.64-34.14) were significantly associated with ERM development.Conclusions: ERM is not rare after cataract surgery. Long-term retinal examination should be required after cataract surgery.

Background and Objectives: Retinopathy of prematurity (ROP) is the leading cause of blindness in preterm infants. We studied the relationship between different perinatal characteristics, i.e., sex; gestational age (GA); birth weight (BW); C-reactive protein (CRP) and lactate dehydrogenase (LDH) concentrations; ventilation, continuous positive airway pressure (CPAP), and surfactant administration; and the incidence of Stage 1–3 ROP. Materials and Methods: This study included 247 preterm infants with gestational age (GA) < 32 weeks that were successfully screened for ROP. Univariate and multivariate binary analyses were performed to find the most significant risk factors for ROP (Stage 1–3), while multivariate multinomial analysis was used to find the most significant risk factors for specific ROP stages, i.e., Stage 1, 2, and 3. Results: The incidence of ROP (Stage 1–3) was 66.40% (164 infants), while that of Stage 1, 2, and 3 ROP was 15.38% (38 infants), 27.53% (68 infants), and 23.48% (58 infants), respectively. Following univariate analysis, multiple perinatal characteristics, i.e., GA; BW; and ventilation, CPAP, and surfactant administration, were found to be statistically significant risk factors for ROP (p < 0.001). However, in a multivariate model using the same characteristics, only BW and ventilation were significant ROP predictors (p < 0.001 and p < 0.05, respectively). Multivariate multinomial analysis revealed that BW was only significantly correlated with Stage 2 and 3 ROP (p < 0.05 and p < 0.001, respectively), while ventilation was only significantly correlated with Stage 2 ROP (p < 0.05). Conclusions: The results indicate that GA; BW; and the use of ventilation, CPAP, and surfactant were all significant risk factors for ROP (Stage 1–3), but only BW and ventilation were significantly correlated with ROP and specific stages of the disease, namely Stage 2 and 3 ROP and Stage 2 ROP, respectively, in multivariate models.

AbstractBACKGROUNDIncreases in circulating LDL cholesterol (LDL-C) and high-sensitivity C-reactive protein (hsCRP) concentrations are significant risk factors for cardiovascular disease (CVD). We assessed direct LDL-C and hsCRP concentrations compared to standard risk factors in the Framingham Offspring Study.METHODSWe used stored frozen plasma samples (−80 °C) obtained after an overnight fast from 3147 male and female participants (mean age, 58 years) free of CVD at cycle 6 of the Framingham Offspring Study. Overall, 677 participants (21.5%) had a CVD end point over a median of 16.0 years of follow-up. Total cholesterol (TC), triglyceride (TG), HDL cholesterol (HDL-C), direct LDL-C (Denka Seiken and Kyowa Medex methods), and hsCRP (Dade Behring method) concentrations were measured by automated analysis. LDL-C was also calculated by both the Friedewald and Martin methods.RESULTSConsidering all CVD outcomes on univariate analysis, significant factors included standard risk factors (age, hypertension, HDL-C, hypertension treatment, sex, diabetes, smoking, and TC concentration) and nonstandard risk factors (non-HDL-C, direct LDL-C and calculated LDL-C, TG, and hsCRP concentrations). On multivariate analysis, only the Denka Seiken direct LDL-C and the Dade Behring hsCRP were still significant on Cox regression analysis and improved the net risk reclassification index, but with modest effects. Discordance analysis confirmed the benefit of the Denka Seiken direct LDL-C method for prospective hard CVD endpoints (new-onset myocardial infarction, stroke, and/or CVD death).CONCLUSIONSOur data indicate that the Denka Seiken direct LDL-C and Dade Behring hsCRP measurements add significant, but modest, information about CVD risk, compared to standard risk factors and/or calculated LDL-C.

We aimed to evaluate the role of pretreatment carcinoembryonic antigen (CEA) and platelet to lymphocyte ratio (PLR) in predicting brain metastasis after radical surgery for lung adenocarcinoma patients. The records of 103 patients with completely resected lung adenocarcinoma between 2013 and 2014 were reviewed. Clinicopathologic characteristics of these patients were assessed in the Cox proportional hazards regression model. Brain metastasis occurred in 12 patients (11.6%). On univariate analysis, N2 stage (P = 0.013), stage III (P = 0.016), increased CEA level (P = 0.006), and higher PLR value (P = 0.020) before treatment were associated with an increased risk of developing brain metastasis. In multivariate model analysis, CEA above 5.2 ng/mL (P = 0.014) and PLR ≥ 120 (P = 0.036) remained as the risk factors for brain metastasis. The combination of CEA and PLR was superior to CEA or PLR alone in predicting brain metastasis according to the receiver operating characteristic (ROC) curve analysis (area under ROC curve, AUC 0.872 versus 0.784 versus 0.704). Pretreatment CEA and PLR are independent and significant risk factors for occurrence of brain metastasis in resected lung adenocarcinoma patients. Combining these two factors may improve the predictability of brain metastasis.

ObjectivesTo evaluate the significance of adenosquamous carcinoma (ASC) compared with adenocarcinoma (AC) in the survival of surgically treated early-stage cervical cancer.MethodsWe retrospectively reviewed the medical records of 163 patients with International Federation of Gynecology and Obstetrics stage IA2 to stage IIB cervical cancer who had been treated with radical hysterectomy with or without adjuvant radiotherapy between January 1998 and December 2008. The patients were classified according to the following: (1) histological subtype (ASC group or AC group) and (2) pathological risk factors (low-risk or intermediate/high-risk group). Survival was evaluated using the Kaplan-Meier method and compared using the log-rank test. Multivariate analysis of progression-free survival (PFS) was performed using the Cox proportional hazards regression model to investigate the prognostic significance of histological subtype.ResultsClinicopathological characteristics were similar between the ASC and AC histology groups. Patients with the ASC histology displayed a PFS rate similar to that of the patients with the AC histology in both the low-risk and intermediate/high-risk groups. Neither the recurrence rate nor the pattern of recurrence differed between the ASC group and the AC group. Univariate analysis revealed that patients with pelvic lymph node metastasis and parametrial invasion achieved significantly shorter PFS than those without these risk factors.ConclusionsCharacteristics of the patients and the tumors as well as survival outcomes of ASC were comparable to adenocarcinoma of early-stage uterine cervix treated with radical hysterectomy. Our results in part support that the management of ASC could be the same as the one of AC of the uterine cervix.

This study was designed to analyze the outcomes of chemotherapy for high-risk gestational trophoblastic neoplasia (GTN) with EMA-CO regimen as primary and secondary protocol in China. Fifty-four patients with high-risk GTN received 292 EMA/CO treatment cycles between 1996 and 2005. Forty-five patients were primarily treated with EMA-CO, and nine were secondarily treated after failure to other combination chemotherapy. Adjuvant surgery and radiotherapy were used in the selected patients. Response, survival and related risk factors, as well as chemotherapy complications, were retrospectively analyzed. Thirty-five of forty-five patients (77.8%) receiving EMA-CO as first-line treatment achieved complete remission, and 77.8% (7/9) as secondary treatment. The overall survival rate was 87.0% in all high-risk GTN patients, with 93.3% (42/45) as primary therapy and 55.6% (5/9) as secondary therapy. The survival rates were significantly different between two groups (χ2= 6.434, P = 0.011). Univariate analysis showed that the metastatic site and the number of metastatic organs were significant risk factors, but binomial distribution logistic regression analysis revealed that only the number of metastatic organs was an independent risk factor for the survival rate. No life-threatening toxicity and secondary malignancy were found. EMA-EP regimen was used for ten patients who were resistant to EMA-CO and three who relapsed after EMA-CO. Of those, 11 patients (84.6%) achieved complete remission. We conclude that EMA-CO regimen is an effective and safe primary therapy for high-risk GTN, but not an appropriate second-line protocol. The number of metastatic organs is an independent prognostic factor for the patient with high-risk GTN. EMA-EP regimen is a highly effective salvage therapy for those failing to EMA-CO.

Deep neck infection (DNI) is a serious disease of deep neck spaces that can lead to morbidities and mortality. Acute epiglottitis (AE) is a severe infection of the epiglottis, which can lead to airway obstruction. However, there have been no studies of risk factors in patients with concurrent DNI and AE. This study was performed to investigate this issue. A total of 502 subjects with DNI were enrolled in the study between June 2016 and August 2021. Among these patients, 30 had concurrent DNI and AE. The relevant clinical variables were assessed. In a univariate analysis, involvement of the parapharyngeal space (OR = 21.50, 95% CI: 2.905–158.7, p < 0.001) and involvement of the submandibular space (OR = 2.064, 95% CI: 0.961–4.434, p < 0.001) were significant risk factors for concurrent DNI and AE. In a multivariate analysis, involvement of the parapharyngeal space (OR = 23.69, 95% CI: 3.187–175.4, p = 0.002) and involvement of the submandibular space (OR = 2.465, 95% CI: 1.131–5.375, p < 0.023) were independent risk factors for patients with concurrent DNI and AE. There were no differences in pathogens, therapeutic managements (tracheostomy, intubation, surgical drainage), or hospital staying period between the 30 patients with concurrent DNI and AE and the 472 patients with DNI alone (all p > 0.05). However, we believe it is significant that DNI and AE are concurrent because both DNI and AE potentially cause airway obstruction, and concurrence of these two diseases make airway protection more difficult. The infections in critical spaces may cause the coincidence of these two diseases. Involvement of the parapharyngeal space and involvement of the submandibular space were independent risk factors associated with concurrent DNI and AE. There were no differences in pathogens between the concurrent DNI and AE group and the DNI alone group.

Abstract Background We investigate the SD-OCT features of sub-inner limiting membrane (sub-ILM) hemorrhage after 577nm laser membranotomy. Methods The ocular fundus photography and SD-OCT of patients who received 577nm laser membranotomy for sub-ILM hemorrhage were assessed from January 2017 to March 2021 in this retrospective cases series study. Results Total of 7 patients (7 eyes) were enrolled in this study, in which 3 were female and 4 were male. The SD-OCT of ILM after laser treatment showed two distinctive features: the ILM falling back to retina (4 cases) or persistent unsealed ILM which forming premacular cavity (3 cases). The SD-OCT of macular fovea after laser treatment showed three features: normal contour (3 cases), macular hole (1 cases) and epiretinal membrane (1 case). The outer retina showed “peg-like” or “patchy-like” structure on the site of ILM attached to retina.Conclusions 577nm laser is effective in treating of sub-ILM hemorrhage and SD-OCT is effective for diagnosis and following-up of sub-ILM hemorrhage.

AimsTo report the 6-year incidence of optical coherence tomography (OCT)-derived age-related changes in drusen volume and related systemic and ocular associations.MethodsChinese adults aged 40 years and older were assessed at baseline and 6 years with colour fundus photography (CFP) and spectral domain (SD) OCT. CFPs were graded for age-related macular degeneration (AMD) features and drusen volume was generated using commercially available automated software.ResultsA total of 4172 eyes of 2580 participants (mean age 58.12±9.03 years; 51.12% women) had baseline and 6-year follow-up CFP for grading, of these, 2130 eyes of 1305 participants had gradable SD-OCT images, available for analysis. Based on CFP grading, 136 (3.39%) participants developed incident early AMD and 10 (0.25%) late AMD. Concurrently, retinal pigment epithelial-Bruch’s membrane (RPE-BrC) volumes decreased, remained stable and increased in 6.8%, 78.5% and 14.7%, respectively, over 6 years. In eyes where RPE-BrC volumes were >0 mm3 at baseline, this was associated with two-fold higher prevalence rate of any AMD at baseline (p<0.001). Multivariable analysis showed that when compared with eyes where RPE-BrC volume was unchanged, volume decrease was significantly associated with older age (OR=1.30; p<0.001), smoking (OR=2.21; p=0.001) and chronic kidney disease (OR=3.4, p=0.008), while increase was associated with older age (OR=1.36; p<0.001) and hypertension (OR=1.43; p=0.016).ConclusionAMD incidence detected at 6 years on CFP and correlated OCT-derived drusen volume measurement change is low. Older age and some systemic risk factors are associated with drusen volume change, and our data provide new insights into relationship between systemic risk factors and outer retinal morphology in Asian eyes.
