- Abstract
Chlorinated pollutants may follow distinct degradation pathways in anaerobic environments compared to aerobic settings. However, the understanding of the behaviors and fate of dichlorodiphenyltrichloroethanes (DDTs) under anaerobic conditions remains limited. To address this knowledge gap, we conducted a study on flooded soil samples collected from three typical paddy fields in China using an integrated approach of enantiomer-specific analysis and compound-specific stable carbon isotope analysis. It is unexpected that the dichlorodiphenyldichloroethane /dichlorodiphenyldichloroethylene ratios (DDD/DDE=(o,p'-DDD+p,p'-DDD)/(o,p'-DDE+p,p'-DDE)) were below 1 in over 90 % of the samples. This might be attributed to the higher recalcitrance of p,p'-DDE, which concentrations were found to be 36 times higher than p,p'-DDD on average. There were 71.7 % of the samples showing enantiomeric fractions (EFs) of o,p'-DDT below 0.5, indicating a preferential accumulation of the (-)-enantiomer. The δ
13 C values of the anaerobic metabolite o,p'-DDD (-24.76 ± 1.35 ‰ to -34.39 ± 0.20 ‰) all deviated negatively from the initial product, while those of the aerobic metabolite o,p'-DDE (-23.61 ± 0.48 ‰ to -38.95 ± 0.81 ‰) displayed either negative or positive deviations. This demonstrates that o,p'-DDD is the primary metabolite of o,p'-DDT under anaerobic conditions. However, no clear correlations were observed between the δ13 C and EF of o,p'-DDT. This study underscores the importance of such an integrated methodology in unraveling the fate and behaviors of DDTs in complex environmental systems., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

- Abstract
Targeted removal of three key refractory toxic organic compounds (TOMs) in 2-butenal manufacturing wastewater (2-BMW) is critical for enhancing pre-treatment by hydrolysis acidification (HA). We investigated the pre-treatment of 2-BMW with HA, coupled with ozonation in this study. Our results indicated that the removal rate of these key TOMs and the detoxification rate reached almost 100% and 46.3%, respectively, by ozonation under only 0.099 mg O
3 /mg chemical oxygen demand (COD). The organic load rate (OLR) reached 10.25 ± 0.43 kg COD/m3 ·d, and the acidification degree (AD) and detoxification efficiency reached 56.0% and 98.3%, respectively, with enhancements of 35.1% and 55.2%, respectively, compared with HA alone. The removal rate of the three key TOMs was improved by > 75%. The degradation pathways of these key TOMs were ring cleavage and ester formation by ozonation, followed by fermentation and acid production by HA. Ultimately, the synergistic role of ozonation and HA was revealed. The preferential cleavage of these key TOMs by ozonation was achieved because of their high electron cloud density and multiple reaction sites, which generated more fermentation-friendly products. The fermentation and acid production reactions may be directly involved in these products. Functional bacteria and key metabolic pathways were also enhanced by ozonation., Competing Interests: Declaration of Competing Interest This work has not been published before in whole or in part or in any language, and it is not under consideration for publication anywhere else.

- Abstract
Background: Stroke during pregnancy is rare, occurring in 30 of 100,000 pregnancies and accounting for 7% of maternal deaths in the United States from 2016 to 2018. Metabolic and bariatric surgery (MBS) has been shown to reduce symptoms of chronic conditions that are risk factors for stroke, including hypertension, hypercholesterolemia, and diabetes in women. However, little is known about the impact of MBS on stroke risk during pregnancy., Objectives: To examine stroke and stroke risk factors including preeclampsia, eclampsia, gestational hypertension, and embolism/thrombosis in women of reproductive age who have had MBS., Setting: We used the National Inpatient Sample, a publicly available data set from the Healthcare Cost and Utilization Project that samples 20% of hospital discharges in the United States., Methods: This cross-sectional study included women between the ages of 20 and 44 years who had a maternal admission code. Weighted logistic regression was conducted to assess the odds of stroke and stroke risk factors in women with a history of MBS compared with other women of reproductive age., Results: Women with a history of MBS have 12% lower adjusted odds of developing preeclampsia/eclampsia and 10% lower adjusted odds of gestational hypertension than women who did not undergo MBS. When stratified by race, the difference was significant in White women (preeclampsia/eclampsia: adjusted odds ratio [aOR] = .89; 95% confidence interval [CI], .81-.98; gestational hypertension: aOR = .91; 95% CI, .83-1.00). Latinas with MBS had significantly lower odds of preeclampsia/eclampsia (aOR = .75; 95% CI, .64-.90)., Conclusions: MBS helps women lose weight and decrease the incidence of some pregnancy-related risk factors for stroke. However, there is a notable racial health disparity., (Copyright © 2023 American Society for Metabolic and Bariatric Surgery. Published by Elsevier Inc. All rights reserved.)

- Abstract
Purpose: Genome-wide association studies have identified multiple genetic variants associated with vertical cup-to-disc ratio (VCDR). Genetic risk scores (GRS) examine the aggregate genetic effect of individual variants on a trait by combining these separate genetic variants into a single measure. The purpose of this study was to construct GRS for VCDR and to determine whether the GRS are associated with VCDR and whether the GRS increase the discriminatory ability for primary open-angle glaucoma (POAG) in a Latino population., Design: Population-based genetic association study., Participants: A total of 4018 Latino participants recruited from Los Angeles., Methods: Weighted and unweighted GRS were constructed using 68 previously reported VCDR single nucleotide polymorphisms (SNPs), as well as SNPs from our own genome-wide association data. Linear and logistic regression analyses examined the associations of GRS with VCDR and POAG, respectively. To evaluate the discriminatory ability of the GRS for POAG, we conducted receiver operating characteristic (ROC) analyses., Main Outcome Measures: The relationship between GRS and VCDR in Latinos., Results: The GRS were associated significantly with VCDR (P < 0.0001), after adjusting for age, gender, central corneal thickness, intraocular pressure, and education. The weighted GRS explained an additional 2.74% of the variation in VCDR. Adding the weighted GRS derived from previously reported SNPs resulted in a moderate improvement in the discriminatory ability for POAG during ROC analyses, yielding an area under the ROC curve (AUC) of 0.735 (95% CI, 0.701-0.768). When our own SNPs were used, the AUC increased significantly to 0.809 (95% CI, 0.781-0.837; P < 0.0001). We obtained similar results for the unweighted GRS., Conclusions: To our knowledge, we identified a novel association between GRS and VCDR and its improvement in the discriminatory ability of POAG in a Latino population., (Published by Elsevier Inc.)

- Abstract
Purpose: Intraocular pressure (IOP) is a major risk factor, as well as the only modifiable risk factor, for glaucoma. Racial differences have been observed in IOP measurements with individuals of African descent experiencing the highest IOP when compared with other ethnic groups. The purpose of this study was to examine the relationship between genetic ancestry and IOP in Latinos., Design: Population-based genetic association study., Participants: A total of 3541 participants recruited from the Los Angeles Latino Eye Study., Methods: Study participants were genotyped using the Illumina OmniExpress BeadChip (∼730K markers). We used STRUCTURE to estimate individual genetic ancestry. Simple and multiple linear regression, as well as quantile regression, analyses were performed to investigate the relationship between genetic ancestry and IOP., Main Outcome Measures: The relationship between genetic ancestry and IOP in Latinos., Results: African ancestry was significantly associated with higher IOP in Latinos in our simple linear regression analysis (P = 0.002). After adjusting for age, gender, body mass index, systolic blood pressure, central corneal thickness, and type 2 diabetes, this association remained significant (P = 0.0005). The main association was modified by a significant interaction between African ancestry and hypertension (P = 0.037), with hypertensive individuals experiencing a greater increase in IOP with increasing African ancestry., Conclusions: To our knowledge, we demonstrate for the first time that African ancestry and its interaction with hypertension are associated with higher IOP in Latinos., (Copyright © 2016 American Academy of Ophthalmology.
