Abstract
BACKGROUND Age-related cataracts are a significant global health issue due to population ageing. More than 70% of older Australians aged 80 or above have clinically significant age-related cataracts. AIM The study aimed to identify factors associated with age-related cataracts among older Australian women 79-90 years. METHOD A 6-year longitudinal analysis of the Australian Longitudinal Study on Women's Health (ALSWH) was conducted on 7117 women from surveys four to six. The women were asked whether they had been diagnosed or treated for cataracts 3 years before each survey. We used generalised estimating equation (GEE) modelling to identify factors independently associated with age-related cataracts. RESULTS At baseline (79-84 years), 44.8% lived in metropolitan Australia, 67.9% had good general health, 26.5% had private health insurance, 30.6% had cataracts, 28.8% had undergone cataract surgery, 12.0% had diabetes, 24.9% had skin cancer, 56.2% had hypertension, 24.0% had a history of falls, 63.0% had visited general practitioner (GP) frequently, and 48.8% were driving themselves as their main means of transport. In the final model, poor general health [adjusted odds ratio (AOR) = 1.23, 95% CI = 1.14, 1.33)], not driving (AOR = 1.09, 95% CI = 1.01, 1.18), having private health insurance (AOR = 1.13, 95% CI = 1.04, 1.23), frequent GP visits (AOR = 1.16, 95% CI = 1.07, 1.25), skin cancer (AOR = 1.26, 95% CI = 1.16, 1.37), hypertension (AOR = 1.13, 95% CI = 1.05, 1.21), and fall (AOR = 1.12, 95% CI = 1.04, 1.22) were significantly associated with the age-related cataracts. CONCLUSIONS Systemic diseases, poor quality of life, driving cessation, and health service use were significantly associated with age-related cataracts in older women.

Abstract
INTRODUCTION Although Cataract Surgery Rate is increasing, the availability of surgery is outstripped by the increasing number of cataract cases as populations age. AIM The study aimed to identify factors associated with cataract surgery uptake in terms of predisposing, enabling, and need factors in very old Australian women. METHOD This study used ALSWH data included 6229 women aged 79-84 to 85-90 years. Women were asked whether they had undergone eye surgery (including cataracts) three years prior to each survey. Generalised estimating equation modelling was used to determine factors associated with these surgeries. RESULT At baseline (2005), more than half of the participants either had undergone surgery (43.5%) or had unoperated cataracts (7.6%). Increasing age (AOR = 1.11, 95% CI = 1.07, 1.15) and being current or ex-smokers (AOR = 1.15, 95% CI = 1.03, 1.29) were associated with higher odds of cataract surgery (predisposing factors). Women who had private health insurance had 27% higher odds of having surgery (AOR = 1.27, 95% CI = 1.16, 1.39) (enabling factor). Need factors of more General Practitioner visits (AOR = 1.16, 95% CI = 1.09, 1.25) and skin cancer (AOR = 1.09, 95% CI = 1.01, 1.17) also increased the odds of cataract surgery. Women who had no difficulty seeing newspaper print were more likely to have had cataract surgery (AOR = 1.35, 95% CI = 1.23, 1.48). CONCLUSION Need factors are the major drivers of cataract surgery; however, predisposing and enabling factors also play a role, including access to private health insurance. This finding indicates some inequity regarding access to cataract surgery in the Australian setting.

Abstract
Background Most estimates of visual impairment and blindness worldwide do not include data from specific minority groups as indigenous populations. We aimed to evaluate frequencies and causes of visual impairment and blindness in a large population sample from the Xingu Indigenous Park. Methods Cross-sectional study performed at Xingu Indigenous Park, Brazil, from 2016 to 2017. Residents from 16 selected villages were invited to participate and underwent a detailed ocular examination, including uncorrected (UVA) and best-corrected visual acuity (BCVA). The main cause of UVA < 20/32 per eye was determined. Results A total of 2,099 individuals were evaluated. Overall, the frequency of visual impairment and blindness was 10.00% (95% CI: 8.72–11.29%) when considering UVA, decreasing to 7.15% (95% CI: 6.04–8.25%) when considering BCVA. For each increasing year on age, the risk of being in the visually impaired or blind category increased by 9% (p < 0.001). Cataracts (39.1%) and uncorrected refractive errors (29.1%) were the most frequent causes of visual impairment and blindness in this population. The main causes among those aged 45 years and more were cataracts (54.5%) while refractive errors were the main cause in adults aged 18 to 45 years (50.0%) and children up to 18 years old (37.1%). Conclusions A higher frequency of visual impairment and blindness was observed in the indigenous population when compared to worldwide estimates with most of the causes being preventable and/or treatable. Blindness prevention programs should focus on accessibility to eye exam, cataract surgeries and eyeglass distribution.

Abstract
Purpose Ultraviolet radiation from sunlight contributes to age-related cataract and skin cancer. The EPHA2 gene is implicated in both these diseases. The purpose of this study was to determine whether age-related cataract and skin cancer are associated in a cohort of older Australians. Methods A cross-sectional study was performed using the Historical Cohort of the Registry of Senior Australians. Individuals aged ≥65 years or aged ≥50 years and of Aboriginal or Torres Strait Islander descent, who had an aged care eligibility assessment between July 2005 and June 2015, and had a history of cataract surgery and/or skin cancer according to the Australian Government Medicare Benefits Schedule dataset, during the 3-year period prior, were evaluated (N = 599,316). A multivariable logistic regression model was used to determine association and multiple hypothesis correction was employed. Results Of the evaluated individuals, 87,097 (14.5%) had a history of cataract and 170,251 (28.4%) a history of skin cancer. Among those with a history of cataract, 20,497 (23.5%), 1127 (1.3%), and 14,730 (16.9%) individuals had a concurrent history of keratinocyte, melanoma, and premalignant/solar keratosis, respectively. Those with a history of cataract were 19% more likely to have a history of skin cancer (odds ratio [OR], 1.19; 95% confidence interval [CI], (1.17–1.21). Co-occurrence of keratinocyte skin cancer was 16% (OR, 1.16; 95% CI, 1.14–1.18), melanoma 21% (OR, 1.21; 95% CI, 1.13–1.29), and premalignant/solar keratosis 19% (OR, 1.19; 95% CI, 1.17–1.22) more in the presence than absence of history of cataract. Conclusions Age-related cataract is positively associated with skin cancer and its subtypes, including premalignant lesions in an older Australian population.

Abstract
Introduction Melanoma is a malignant tumour and is the leading cause of death in patients with skin tumours. Aim Kaempferol belongs to a class of flavonoids, and is associated with many biological functions such as anti-inflammatory, anti-oxidation and anti-cancer. However, the inhibitory effect of kaempferol on melanoma still remains unclear. Material and methods The effect of kaempferol on melanoma was determined by conducting both in vitro and in vivo experiments using MTT assay and flow cytometry. Results The in vitro results revealed that kaempferol obviously inhibited cell viability of melanoma B16 cells, induced cell cycle arrest and cell apoptosis. The in vivo results showed that kaempferol effectively inhibited the growth of mice xenografts. More importantly, kaempferol down-regulated the number of MDSC cells and up-regulated the number of NKT cells and CD8 T cells in the spleen. Conclusions Taken together, these findings indicate that kaempferol might play an inhibitory role in the growth of melanoma by enhancing anti-tumour immunity of organisms.

Abstract
Emerging evidence has shown that cinobufagin, as an active ingredient of Venenum Bufonis, inhibits tumor development. The aim of this study was to investigate the inhibitory effects of cinobufagin on A375 human malignant melanoma cells. MTT and colony formation assays showed that cinobufagin significantly inhibited A375 cell proliferation and cell colony formation. Additional studies demonstrated that cinobufagin markedly increased the levels of ATM serine/threonine kinase (ATM) and checkpoint kinase 2 (Chk2) and decreased the levels of cell division cycle 25C (CDC25C), cyclin-dependent kinase 1 (CDK1), and cyclin B, subsequently inducing G2/M cell cycle arrest in A375 cells. Moreover, cinobufagin clearly inhibited the levels of phosphoinositide 3-kinase (PI3K), phosphorylated PI3K (p-PI3K), AKT, p-AKT, and B-cell lymphoma 2 (Bcl-2). By contrast, it increased the levels of Bcl-2-associated death promoter, Bcl-2-associated X, cytoplasmic cytochrome C, and apoptotic protease activating factor 1, leading to increased levels of cleaved caspase-9 and cleaved caspase-3, resulting in the apoptosis of A375 cells. Together, these results indicate that cinobufagin can induce cell cycle arrest at the G2/M phase and apoptosis, leading to inhibition of A375/B16 cell proliferation. Thus, cinobufagin may be useful for melanoma treatment.
