Purpose: To compare the efficacy of a combination of anti-vascular endothelial growth factor (VEGF) and endpoint management (EpM) grid laser versus monotherapy with anti-VEGF in the management of diabetic macular edema (DME). Methods: This was a prospective, multicenter, open-label, nonrandomized interventional study (NCT02462304). Anti-VEGF therapy consisted of one initial injection administered pro re nata in both groups. EpM laser was performed within 1 month after the first anti-VEGF injection. The main outcome evaluated was the number of anti-VEGF injections performed in 6 months. Best-corrected visual acuity (BCVA) and central foveal thickness (CFT) were also evaluated monthly. The anti-VEGF agent used in Japan and Hong Kong was ranibizumab, while bevacizumab was used in Korea. Results: This study enrolled a total of 42 subjects, with 19 (45.2%) allocated to the monotherapy arm and 23 (54.8%) allocated to the combination arm (EpM group). Overall, there was no significant difference in the number of injections between patients in the two groups (+0.12, p = 0.81). Mixed regression analysis with all the covariates plus an interaction term for the ranibizumab/bevacizumab and the monotherapy/combination arm showed that the EpM group needed 0.94 less injections (95% confidence interval [CI], -1.73 to -0.15; p = 0.02). The logarithm of the minimum angle of resolution BCVA at 24 weeks was significantly improved in the monotherapy arm (p = 0.03), but not in the EpM group (p = 0.09). CFT at 24 weeks was significantly improved in both groups (p < 0.01). Conclusions: These data suggest that combination therapy with the EpM laser may be effective for reducing the number of anti-VEGF injections required for DME treatment.

Purpose The association of physical activity with the risk of bladder cancer remains inconsistent among Asian populations. We aimed to examine the association in a large Japanese cohort.Materials and Methods In a population-based prospective cohort study, a total of 50,374 Japanese adults aged 40-79 years without a history of cancer or cardiovascular disease who had information on physical activity from self-administrated questionnaires were used for analysis. We performed Cox proportional hazard models to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) for incident bladder cancer after adjusting for several potential confounders.Results During the median 17.5 years of follow-up, 153 incident bladder cancers (116 men and 37 women) were identified. After the multivariable adjustment, HRs (95% CI) of bladder cancer concerning those with recreational sports participation of 1-2 hr/wk, 3-4 hr/wk, and 5 hr/wk and more were 0.67 (0.38-1.20), 0.79 (0.36-1.74), and 0.28 (0.09-0.89), respectively (p for trend=0.017). Compared with mostly sitting at the workplace, occupational physical activity of standing and walking were associated with a lower risk of bladder cancer (HR, 0.53 [95% CI, 0.32 to 0.85]). Hours of daily walking were not associated with the risk. The lower risk of bladder cancer was more evident for recreational sports (HR, 0.33 [95% CI, 0.10 to 1.00]), and for occupational standing and walking activity at work (HR, 0.57 [95% CI, 0.33 to 0.98]) among men.Conclusion Recreational sports participation and occupational physical activity were inversely associated with the risk of bladder cancer among Japanese, especially in men.
