Abstract
OBJECT This study aims to investigate the molecular mechanism of NDRG2 (N-myc downstream-regulated gene 2) in the cell senescence of lens endothelial cells. METHODS Lens endothelial cells (SRA01/04) were irradiated with UVB at different times. Cell viability was measured by CCK-8 kit and cell cycle was detected by flow cytometry. Cell senescence was detected using SA-β-gal staining. Western blot was utilized to detect the expressions of p53, p21 and NDRG2. TUNEL staining and flow cytometry were used to detect apoptosis and pyroptosis. RESULTS UVB-irradiation significantly induces cell senescence and the expression of NDRG2, p53 and p21 in SRA01/04 cells was up-regulated. Down-regulation of NDRG2 inhibited UVB-induced cell senescence, significantly reversed pyroptosis and promoted cell proliferation. UVB-induced pyroptosis is closely related to caspase-1/NLRP3 axis. CONCLUSION Our study confirmed downregulation of NDRG2 significantly inhibited UVB radiation-induced cell senescence by regulating caspase-1/NLRP3-mediated pyroptosis.

Abstract
OBJECTIVE To assess the cardiovascular risk (CV risk) change following bilateral phacoemulsification cataract surgery. METHODS We performed a retrospective observation cohort study on 112 selected patients who underwent uncomplicated bilateral cataract surgery at Centro Hospitalar de Entre o Douro e Vouga (CHEDV) between 2018 and 2019. This patient cohort was further subdivided in 2 different groups: Good VA - no to mild visual impairment, ≤0.48 LogMAR; Bad VA - moderate to severe visual impairment, >0.48 LogMAR. We compared the changes in the CV risk score components in our patient cohort and between subgroups Good VA and Bad VA, before and after surgery, using paired t-test or Wilcoxon rank-sum test, and repeated measures ANOVA with Tukey post-hoc tests, respectively. Visual Acuity (VA) before and after surgery was correlated with the patients' CV risk score. At last, linear regression models were built to explain changes in CV risk variables considering the change in VA. RESULTS Cataract surgery resulted in improved VA. Notably, following surgery our patient cohort showed reduced low-density lipoprotein (LDL) levels after surgery, from 111.17±36.26 mg/dL to 104.22±37.53 mg/dL, and reduced systolic arterial pressure (SAP), from 139.1±15.0 mmHg to 133.7±12.0 mmHg. Ultimately, this translated to an improved CV risk score within 6 months of cataract surgery, from 17.39±11.44% to 16.51±11.27%. Of note, these improvements were mostly present in the Bad VA group of patients, where baseline VA and incidence of dyslipidemia were worse. CONCLUSION Our results suggest that phacoemulsification cataract surgery may be an important tool in addressing CV risk.

ANNALS OF TRANSLATIONAL MEDICINE 2022; 9:1640.

Abstract
Background Body mass index (BMI) has been reported to be associated with age-related cataract, whereas its impact on early onset cataract (EOC) remains unknown. Methods A total of 73,007 individuals aged 45–55 years who had no previous cataract surgeries at baseline were enrolled from the population-based 45 and Up Study. BMI was calculated based on self-reported height and weight from the baseline questionnaire. Data on cataract surgeries were obtained from the Medicare Benefits Schedule database. EOC was defined as cataract surgically treated prior to 65 years of age. A Cox proportional hazards regression was used to assess the association between BMI and the incidence of EOC during the follow-up. Results A total of 1,764 participants underwent cataract surgery over 643,717 person-years of follow-up. No significant association was observed between BMI and EOC (P for trend 0.35). Among participants who drank 5 to 7 alcoholic drinks per week, a 73% and 27% reduction in the risk of EOC was observed in participants with a BMI of 18.5–19.99 and 25.0–27.49 kg/m2, respectively, compared to those with a BMI of 20.0–22.49 kg/m2. Conclusions No association was identified between BMI and the incidence of EOC. Moderate alcohol intake may be protective against EOC.

Relationship between Cataract Surgery and Mortality in Elderly Patients with Cataract: Nationwide Population-Based Cohort Study in South Korea. J Pers Med 2021; 11:jpm11111128. [PMID: 34834480 PMCID: PMC8625327 DOI: 10.3390/jpm11111128] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Revised: 10/27/2021] [Accepted: 10/29/2021] [Indexed: 11/17/2022] Open
Abstract
We aimed to investigate the relationship between cataract surgery and all-cause and cause-specific mortality in Korean elderly patients with cataract using the Korean National Health Insurance Service-Senior cohort database. Elderly patients (≥60 years) diagnosed with cataract from 2002 through 2012 were included. The baseline characteristics included demographics and systemic and ocular comorbidities. Adjusted Cox regression models with time-varying covariates for cataract surgery were used to assess the relationship between cataract surgery and mortality. The study cohort included 241,062 patients, of whom 127,941 were in the cataract surgery group and 113,121 were in the cataract diagnosis group. The incidence of all-cause mortality was 3.62 deaths/100 person-years and 3.19 deaths/100 person-years in the cataract surgery and cataract diagnosis groups, respectively. Cataract surgery was associated with a decreased hazard of all-cause mortality after adjusting for demographics as well as systemic and ocular comorbidities (hazard ratio (HR), 0.93; p < 0.001). A protective association was noted between cataract surgery and mortality from vascular (HR, 0.92; p < 0.001) or neurologic (HR, 0.64; p < 0.001) causes. Patients with cataract who were 85 years of age and older, women, those who had lower income, and a Charlson comorbidity index score of 5 or more, or those without glaucoma revealed the largest reductions in mortality hazards resulting from cataract surgery.

Abstract
BACKGROUND Pregnancy-related risk factors for cataract are understudied, including the possibility that preeclampsia increases the risk of cataract later in life. OBJECTIVE We sought to evaluate the long-term risk of cataract extraction following a preeclamptic pregnancy. STUDY DESIGN We carried out a historic cohort study of 1,108,541 women who delivered at least 1 infant in any hospital in the province of Quebec, Canada, from 1989 through 2013, including 64,350 with preeclampsia and 5732 with cataract extractions. We categorized preeclampsia by onset time and severity, and followed up women for up to 25 years after delivery. We calculated the incidence of inpatient cataract extraction for women with and without preeclampsia, and used Cox proportional hazard models to estimate hazard ratios and 95% confidence intervals for later risk of cataract extraction, adjusting for age at first delivery, total parity, metabolic disease, asthma, socioeconomic deprivation, and time period. RESULTS Women with preeclampsia had a higher incidence of cataract extraction compared with no preeclampsia (21.0 vs 15.9/1000) and 1.20 times the risk (95% confidence interval, 1.08-1.34). Women with early-onset preeclampsia had 1.51 times the risk of cataract extraction compared with no preeclampsia (95% confidence interval, 1.14-2.00), whereas women with late-onset preeclampsia had 1.16 times the risk (95% confidence interval, 1.04-1.30). Risk was elevated by about 20% for both severe and mild preeclampsia. Preeclampsia with diabetes was associated with significantly greater risk (hazard ratio, 4.32; 95% confidence interval, 3.60-5.19). CONCLUSION Women with preeclampsia, particularly preeclampsia of early onset or with diabetes, may have greater risk of cataract later in life. The underlying pathways linking preeclampsia with cataract require further investigation.
