Chi YC, Chu WL, Chen KJ, Cheng KC. Morphological Change in Optical Coherence Tomography and Functional Outcomes in Epiretinal Membrane Peeling with or without SF6 Tamponade. Diagnostics (Basel) 2024; 14:1483. [PMID: 39061620 PMCID: PMC11275800 DOI: 10.3390/diagnostics14141483] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2024] [Revised: 07/02/2024] [Accepted: 07/06/2024] [Indexed: 07/28/2024] Open
Abstract
BACKGROUND The present study compares the anatomical and functional outcomes (best-corrected visual acuity (BCVA) and central macular thickness (CMT)) among membrane peeling with or without SF6 tamponade in patients with epiretinal membrane. METHODS We retrospectively reviewed patients diagnosed with macular pucker who underwent pars plana vitrectomy and membrane peeling in a tertiary center in Taiwan from January 2021 to December 2022. Subjects were categorized into with or without SF6 tamponade groups (SF6 group and BSS group). Postoperative intraocular pressure and complications were documented. Logistic regression analyses were performed to identify the prognostic factors during follow-up. RESULTS A total of 89 eyes were enrolled, including 34 eyes in the BSS group and 55 eyes in the SF6 group. The mean age was 66 years old, and a female predilection was demonstrated. Both groups possessed statistically significant improvement in BCVA and CMT after the operation. There was no significant difference in CMT between the groups at any time of observation, yet we observed significant differences in baseline BCVA and BCVA at last follow-up among the two groups. Both groups yielded an approximate enhancement of LogMAR 0.3 in BCVA postoperatively. There was no significant difference noted in postoperative IOP between the two groups. CONCLUSION Membrane peeling with or without SF6 tamponade yields comparable outcomes anatomically and functionally. This may indicate that SF6 tamponade for idiopathic macular pucker surgery may not provide extra benefit, and therefore warrants reconsideration as standard procedure.

Graefes Arch Clin Exp Ophthalmol 2024; 262:1455-1463. [PMID: 38108907 DOI: 10.1007/s00417-023-06330-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Revised: 11/20/2023] [Accepted: 12/01/2023] [Indexed: 12/19/2023] Open
Abstract
PURPOSE To describe the different types of vitreomacular interface abnormalities (VMIA) seen on optical coherence tomography (OCT) in type 2 macular telangiectasia (MacTel) and explain the possible reasons for its development. METHODS In this retrospective cross-sectional study, type 2 MacTel eyes with macular volumetric OCT imaging protocol were included to identify different types of VMIA such as abnormal PVD, vitreomacular traction (VMT), ERM, and lamellar and full-thickness macular hole. The VMIA findings were then correlated with different MacTel disease stages and visual acuity. RESULTS One thousand forty-three OCTs of 332 type 2 MacTel eyes from 169 patients at different visits were examined. VMIA was detected in 709 (68%) of those OCT scans in 216 (65%) eyes. There were 273 (39%), 31 (4%), 89 (13%), 7 (1%), and 381 (54%) OCT scans with vitreomacular adhesion, VMT, ERM, and inner and outer lamellar macular holes discovered respectively. VMIA eyes had a high frequency of abnormal PVD (p = 0.001) and retinal pigment clumps (RPCs) [p = 0.032]. Eyes with abnormal PVD (p = 0.034) and RPC (p = 0.000) had a higher rate of ERM development. RPC was linked to an increased risk of developing ERM (odd ratio 2.472; 95% CI 1.488-4.052). RPC and ERM contributed significantly to poor visual acuity (0.661 ± 0.416, 20/92). CONCLUSION OCT reveals a high frequency of VMIA in advanced type 2 MacTel eyes. RPC could be responsible for the development of anomalous PVD, as well as subsequent VMIAs and ERM. Additional work is required to examine the long-term changes and surgical outcomes of these eyes.

Chen W, Sun S. Clinical Application of a Multiparameter-Based Nomogram Model in Predicting Preeclampsia. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2022; 2022:7484112. [PMID: 35733627 PMCID: PMC9208951 DOI: 10.1155/2022/7484112] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/23/2022] [Accepted: 05/21/2022] [Indexed: 12/04/2022]
Abstract
Based on single-center data, the related predictive factors of preeclampsia (PE) were investigated, and a nomogram prediction model was established and validated. A retrospective collection of 93 PE patients admitted to our hospital from January 2019 to January 2021 were included in the PE group. In addition, non-PE pregnant women were selected for physical examination during the same period for matching, and 170 normal pregnant women who met the matching conditions were found as the normal pregnancy group. Clinical data of the selected candidates were collected. The risk factors of PE were screened by logistic regression analysis, and the lipopograph prediction model was constructed and verified. Logistic analysis results showed that age (OR = 3.069, 95% CI = 1.233-7.638), prepregnancy BMI (OR = 2.896, 95% CI = 1.193-7.029), vitamin E deficiency (OR = 2.803, 95% CI = 1.134-6.928), 25-(OH)D (OR = 0.944, 95% CI = 0.903∼9.988), PLGF (OR = 0.887, 95% CI = 0.851∼0.924), PAPP-A (OR = 1.240, 95% CI = 1.131∼1.360), and PI (OR = 6.376, 95% CI = 1.163∼34.967) were the independent risk factors for PE prediction (P < 0.05). The ROC curve showed that the AUC of the model for predicting the risk of PE was 0.957 (95% CI: 0.935-0.979), and the specificity and sensitivity were 0.912 and 0.892, respectively. H-L goodness of the fit test showed that there was no statistical significance in the deviation between the actual observed value and the predicted value of the risk in the line graph model (χ 2 = 7.001, P=0.536). The bootstrap test was used for internal verification, and the original data were repeatedly sampled 1000 times. The average absolute error of the calibration curve is 0.014, and the fitting degree between the calibration curve and the ideal curve is good. Age, prepregnancy BMI, lack of vitamin E, 25-(OH)D, PLGF, PAPP-A, and PI are independent risk factors for predicting PE. The establishment of a nomogram prediction model based on the above parameters can help identify PE high-risk groups in the early clinical stage and provide a reference for individualized clinical diagnosis and treatment.

First trimester serum PAPP-A is associated with placenta accreta: a retrospective study. Arch Gynecol Obstet 2021; 303:645-652. [PMID: 33515274 DOI: 10.1007/s00404-020-05960-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2020] [Accepted: 12/28/2020] [Indexed: 10/22/2022]
Abstract
PURPOSE Our objective of this study was to investigate whether first trimester serum pregnancy-associated plasma protein-A (PAPP-A) differed amongst pregnancies with placenta previa-accreta and non-adherent placenta previa and healthy pregnancies by a retrospective cohort analysis. METHODS A total of 177 pregnant females were included in the study, as follows: 35 cases of placenta previa-accreta, 30 cases of non-adherent placenta previa, and 112 cases of BMI and age matched, healthy pregnant controls. PAPP-A multiples of the median (MoM) were acquired from laboratory data files in 1 January 2017-30 September 2019. The probable maternal serum biochemical predictor of placenta accreta was analyzed by using multiple logistic regression analysis. RESULTS PAPP-A MoM of placenta previa-accreta group was significantly higher than those of the non-adherent placenta previa group and control group (p = 0.009 < 0.05, p < 0.001). Serum PAPP-A was found to be significantly positively associated with placenta accreta after adjusted gestational week at time of blood sampling, BMI, age, smoking, and previous cesarean section history (OR: 3.51; 95% CI: 1.77-6.94; p = 0.0003 < 0.05). In addition, smoking (OR: 9.17; 95% CI: 1.69-49.62; p = 0.010 < 0.05) and previous cesarean section history (OR: 2.75; 95% CI: 1.23-6.17; p = 0.014 < 0.05) were also significantly associated with placenta accreta. CONCLUSION Increased first trimester serum PAPP-A was significantly positively associated with placenta accreta, suggesting that the potential role of PAPP-A in identifying pregnancies at high risk for placenta accreta. Smoking and previous cesarean section history may be the risk factors for accreta in placenta previa patients.
