Abstract
PURPOSE To evaluate the efficacy and safety of a topical ophthalmic suspension combination of povidone-iodine 0.6% (PVP-I) and dexamethasone 0.1% (DEX) for infectious and inflammatory components of bacterial conjunctivitis. DESIGN Randomized, double-masked, multicenter, phase 3 clinical trial. METHODS Subjects of all ages (those <3 months had to be full-term) with a diagnosis of bacterial conjunctivitis were randomized 3:1:3 to either PVP-I/DEX, PVP-I alone, or placebo. The primary endpoint was clinical resolution in the study eye, and the key secondary efficacy endpoint was bacterial eradication, both at the day 5 visit. Adverse events (AEs) were documented at all visits. RESULTS Overall, 753 subjects were randomized (intent-to-treat [ITT] population; PVP-I/DEX [n = 324]; PVP-I [n = 108]; placebo [n = 321]); mean and standard deviation (SD) age was 44.3 (22.9) years, and most were female (61.2%) and white (78.1%). In all treatment groups, mean treatment compliance was >98%. The modified ITT population for the efficacy analysis comprised 526 subjects. In the study eye at the day 5 visit, clinical resolution was achieved by 50.5% (111/220) subjects in the PVP-I/DEX group vs 42.8% (95/222) in the placebo group (P = .127), and bacterial eradication was achieved by 43.3% (94/217) and 46.8% (102/218), respectively (P = .500). Treatment-emergent AEs were experienced by 32.8% (106/323), 39.8% (43/108), and 19.0% (61/321) of subjects in the safety population treated with PVP-I/DEX, PVP-I, and placebo, respectively (most mild in severity). CONCLUSION In this study, PVP-I/DEX did not demonstrate additional benefit in clinical efficacy compared with placebo in subjects with bacterial conjunctivitis.

Abstract
PURPOSE To test the safety and preliminary efficacy of rapid, nonpharmacologic anesthesia via cooling for intravitreal injections. DESIGN Single-center, randomized phase 1 dose-ranging safety study (ClinicalTrials.gov identifier, NCT02872012). PARTICIPANTS Adults 18 years of age or older with a diagnosis of exudative macular degeneration or diabetic macular edema requiring bilateral anti-vascular endothelial growth factor therapy were included. METHODS A handheld device was developed to provide anesthesia via cooling to a focal area on the surface of the eye before intravitreal treatment (IVT). In 22 patients undergoing bilateral IVT, 1 eye was randomized to receive standard of care (SOC) lidocaine-based anesthesia and the other eye received cooling-anesthesia at 1 of 5 different temperatures and cooling times. Subjective pain was assessed via the visual analog scale (VAS; range, 1-10) at 2 time points: (1) immediately after IVT and (2) 4 hours after IVT. Treated eyes were assessed for ocular safety 24 hours after IVT. MAIN OUTCOME MEASURES We determined the occurrence of adverse events in eyes treated with cooling anesthesia. Mean VAS pain scores immediately after IVT and 4 hours after IVT in eyes receiving cooling anesthesia were compared with eyes receiving SOC. RESULTS A total of 44 eyes were treated, 22 with cooling anesthesia and 22 with SOC. No dose-related toxicity was found with cooling anesthesia. Mild, transient adverse events were recorded in 32% of patients treated with cooling anesthesia versus 44% of patients receiving SOC. The mean±standard error of the mean (SEM) VAS pain scores immediately after intravitreal injection were 2.3 ± 0.4 for patients receiving SOC and 2.2 ± 0.6 in patients receiving -10° C cooling anesthesia (P = 0.8). Mean±SEM pain scores 4 hours after injection were 1.6 ± 0.4 for SOC and 1.2 ± 0.5 in the combined -10° C arms (P = 0.56). Total mean±SEM procedure time was 124 ± 5 seconds for patients treated with cooling anesthesia versus 395 ± 40 seconds for SOC (P < 0.0001). CONCLUSIONS Ultra-rapid cooling of the eye for anesthesia was well tolerated, with -10° C treatment resulting in comparable levels of anesthesia to SOC with a reduction in procedure time.

Abstract
INTRODUCTION Stomatitis is a frequent adverse event in patients undergoing chemotherapy for breast cancer. Stomatitis can hamper oral nutrition resulting in malnutrition, reduce quality of life and introduce the need for dose reductions and interruption of chemotherapy; however, there is currently no standard approach for preventing chemotherapy-induced stomatitis. We aimed to assess the safety and efficacy of a dexamethasone-based elixir mouthwash for preventing chemotherapy-induced stomatitis in patients with early breast cancer. METHODS AND ANALYSIS In this multicenter, randomised, controlled phase 2 trial, we will randomly assign 120 women with early breast cancer undergoing chemotherapy to use of a dexamethasone-based elixir or standard oral care, to compare their preventive effects on chemotherapy-induced stomatitis. Patients will be assigned in a 1:1 ratio. Patients in the intervention group will receive chemotherapy, oral care and a dexamethasone-based elixir (10 mL 0.1 mg/mL; swish for 2 min and spit, four times daily for 9 weeks), and patients in the control group will receive chemotherapy and oral care. The primary endpoint is the difference in incidence of stomatitis between the two groups. The sample size allows for the detection of a minimum difference of 20% in the incidence of stomatitis between the two groups. Secondary endpoints are severity of stomatitis, duration of stomatitis, completion rate of chemotherapy and adverse events. ETHICS AND DISSEMINATION All participants signed a written consent form, and the study protocol has been reviewed and approved by the Clinical Research Review Board of Nagasaki University (CRB7180001). TRIAL REGISTRATION NUMBER UMIN Clinical Trials Registry (UMIN000030489).

Abstract
Asthma resistance to glucocorticoid treatment is a major health problem with unclear etiology. Glucocorticoids inhibit adrenal androgen production. However, androgens have potential benefits in asthma. HSD3B1 encodes for 3β-hydroxysteroid dehydrogenase-1 (3β-HSD1), which catalyzes peripheral conversion from adrenal dehydroepiandrosterone (DHEA) to potent androgens and has a germline missense-encoding polymorphism. The adrenal restrictive HSD3B1(1245A) allele limits conversion, whereas the adrenal permissive HSD3B1(1245C) allele increases DHEA metabolism to potent androgens. In the Severe Asthma Research Program (SARP) III cohort, we determined the association between DHEA-sulfate and percentage predicted forced expiratory volume in 1 s (FEV1PP). HSD3B1(1245) genotypes were assessed, and association between adrenal restrictive and adrenal permissive alleles and FEV1PP in patients with (GC) and without (noGC) daily oral glucocorticoid treatment was determined (n = 318). Validation was performed in a second cohort (SARP I&II; n = 184). DHEA-sulfate is associated with FEV1PP and is suppressed with GC treatment. GC patients homozygous for the adrenal restrictive genotype have lower FEV1PP compared with noGC patients (54.3% vs. 75.1%; P < 0.001). In patients with the homozygous adrenal permissive genotype, there was no FEV1PP difference in GC vs. noGC patients (73.4% vs. 78.9%; P = 0.39). Results were independently confirmed: FEV1PP for homozygous adrenal restrictive genotype in GC vs. noGC is 49.8 vs. 63.4 (P < 0.001), and for homozygous adrenal permissive genotype, it is 66.7 vs. 67.7 (P = 0.92). The adrenal restrictive HSD3B1(1245) genotype is associated with GC resistance. This effect appears to be driven by GC suppression of 3β-HSD1 substrate. Our results suggest opportunities for prediction of GC resistance and pharmacologic intervention.

Abstract
OBJECTIVE Clinical trial results have shown that, in glucocorticoid-treated patients, treatment with denosumab 60 mg subcutaneously once every 6 months (Q6M) increased spine and hip bone mineral density (BMD) at month 12 significantly more than treatment with risedronate 5 mg orally once daily (QD). The present analysis was performed to compare efficacy and characterize safety through month 24. METHODS This phase III study enrolled men and women ≥18 years old who had received ≥7.5 mg daily prednisone or equivalent for <3 months (glucocorticoid-initiating) or for ≥3 months (glucocorticoid-continuing) before screening. All patients <50 years old had a history of osteoporotic fracture. Glucocorticoid-continuing patients ≥50 years old had T scores of -2.0 or less (or -1.0 or less with fracture history). Patients were randomized (1:1) to receive denosumab 60 mg subcutaneously Q6M or risedronate 5 mg orally QD for 24 months, with daily calcium and vitamin D. RESULTS Of 795 patients, 590 (74.2%) completed the study (in the glucocorticoid-initiating group, 109 of 145 patients treated with denosumab and 117 of 145 patients treated with risedronate; in the glucocorticoid-continuing group, 186 of 253 patients treated with denosumab and 178 of 252 patients treated with risedronate). Denosumab was superior to risedronate in increasing lumbar spine and total hip BMD at all time points assessed, among glucocorticoid-initiating patients (24-month lumbar spine: BMD increase of 6.2% versus 1.7%, respectively [P < 0.001]; 24-month total hip: BMD increase of 3.1% versus 0.0% [P < 0.001]) and among glucocorticoid-continuing patients (24-month lumbar spine: BMD increase of 6.4% versus 3.2% [P < 0.001]; 24-month total hip: BMD increase of 2.9% versus 0.5% [P < 0.001]). Adverse events, serious adverse events (including infections), and fractures were similar between treatment groups. CONCLUSION Denosumab was superior to risedronate in terms of increases in spine and hip BMD through month 24, and the safety profile was similar between treatment groups. Denosumab may offer a new osteoporosis treatment option for glucocorticoid-treated patients.

Abstract
PURPOSE It was hypothesized that tear protein biomarkers could predict the effects of topical steroid treatment and desiccating stress in patients with dry eye disease (DED). To test this concept, a randomized, double-masked, controlled clinical trial with 41 patients was conducted. METHODS The patients were treated topically with either 0.1% fluorometholone (FML) or polyvinyl alcohol (PA). Tear samples were collected using 1 μl glass capillaries at recruitment into the study and after a 3-week treatment period, both before and after 2 h exposure to desiccating stress, in a controlled environment chamber. Relative quantification of tear proteins was conducted by NanoLC-MSTOF using sequential window acquisition of all theoretical mass spectra (SWATH). Ocular surface integrity (corneal and conjunctival staining and conjunctival hyperemia) was selected as the key DED-related sign and analyzed with proteomic data. Analysis of covariance (ANCOVA) and linear models were used to analyze the data with R. RESULTS 758 proteins were identified and relatively quantified from each tear sample. Analysis revealed 9 differentially expressed proteins between FML and PA treatments after 3 weeks and 7 after desiccating stress (P < 0.05). We also identified several differentially expressed proteins at the initial collection, which could be used to predict changes of conjunctival and corneal staining and conjunctival hyperemia after FML treatment and after desiccating stress. These proteins include complement C3 (C3) and calmodulin like 5 (CALML5), which could also differentiate the severity of DED at baseline. CONCLUSIONS The identified proteins could be further used as biomarkers to identify patients most benefiting from FML treatment.

Abstract
PURPOSE To compare the results of intravitreal bevacizumab (IVB) injection alone or in combination with intravitreal 1 mg triamcinolone acetonide (IVT) in center-involved diabetic macular edema. METHODS In this randomized clinical trial study, ninety-two eyes of 46 patients with bilateral center-involved diabetic macular edema and no previous treatment were included in the study. One eye of each patient was randomly assigned to 1.25 mg of IVB injection or combination of 1.25 IVB and 1 mg IVT. Evaluation of best-corrected visual acuity (BCVA), central macular thickness (CMT), intraocular pressure (IOP) and grading of lens opacity was conducted at baseline, and weeks 2, 4, 6, 8, 12 and 24 after treatment. Retreatment was performed at a 6-week interval whenever indicated based on CMT. RESULTS Between the groups, BCVA changes were not statistically different until 24-week follow-up (P > 0.05), but at 24 weeks after treatment, BCVA improvement was significantly better in IVB group (P = 0.049). Significant CMT reduction was observed in each group along the follow-up period (P = 0.001). The mean CMT reduction was more significant in combination (IVB + IVT) group at 2 weeks of follow-up (P < 0.001), but CMT changes were not significant between the groups at weeks 12th and 24th after injection. Overall, retreatment was applied for 59 eyes up to 24 weeks (33 in the IVB group, 26 in the IVB + IVT group). Among patients with 2 or more injections, number of injections was significantly lower in IVB + IVT group (P = 0.043). Three eyes within IVB + IVT group developed IOP rise beyond 21 mmHg, which were controlled with topical anti-glaucoma medications within 1 week. Changes in lens opacity were not significant between two groups. CONCLUSION Eyes treated with IVB plus 1 mg IVT injections had more significant reduction in CMT in early post-injection, but this effect was transient. Although after 24 weeks visual acuity improvement was better in IVB group, combination therapy may decrease the number of injections. Combining 1 mg of intravitreal triamcinolone with bevacizumab was not accompanied with significant side effects.

Abstract
OBJECTIVES Minodronic acid hydrate, an oral bisphosphonate, has a greater inhibitory effect on bone resorption than do other approved drugs; however, this has been studied only in patients with primary osteoporosis. Here, we administered minodronic acid hydrate to patients with steroid-induced osteoporosis who have been treated with steroids for rheumatoid arthritis or other collagen diseases, and the efficacy and safety of minodronic acid hydrate were prospectively investigated. METHODS Twenty-five patients treated in our rheumatology clinic received minodronic acid hydrate 1 mg/day. The changes in bone mineral density (BMD) and bone turnover markers were investigated at 3 and 6 months, and adverse events, including the presence or absence of an incident osteoporotic fracture, were examined over a period of 6 months. RESULTS Percent changes in BMD of the lumbar spine and femur significantly increased. The values of bone turnover markers significantly decreased. There were no patients with a radiographically apparent incident fracture. Adverse events included toothache for which the patient discontinued the treatment and three cases of gastrointestinal disorder that did not lead to discontinuation, and thus minodronic acid hydrate was well tolerated. CONCLUSIONS Here, we show that minodronic acid hydrate is effectively and safely used for treatment of steroid-induced osteoporosis.

Abstract
OBJECTIVE To investigate the effects of fluocinolone acetonide (FAc) on the progression to proliferative diabetic retinopathy (PDR) and the impact of FAc on changes in Early Treatment Diabetic Retinopathy Study (ETDRS) diabetic retinopathy (DR) severity scale (DRSS) grade during the Fluocinolone Acetonide in Diabetic Macular Edema (FAME) A and B Phase III clinical trials. DESIGN Post hoc analysis of data from the 36-month prospective, randomized, FAME A and B trials. PARTICIPANTS Patients with diabetic macular edema (DME) who received sham control or FAc 0.2 or 0.5 μg/day. METHODS A masked reading center (University of Wisconsin-Madison) determined DRSS grade and retinal perfusion status using standard 7-field stereo fundus photography and fluorescein angiography, respectively. Retinopathy changes over time were determined by DRSS step differences from baseline to month 36. Pairwise comparisons between the 3 treatment groups were performed using a log-rank test without adjustment for covariates, with the primary comparison between sham control and 0.2 μg/day FAc. MAIN OUTCOME MEASURES Study eye progression to PDR based on a composite clinical outcome of (1) progression from nonproliferative diabetic retinopathy (NPDR) to PDR based on graded fundus photographs, (2) panretinal photocoagulation (PRP), or (3) pars plana vitrectomy (PPV) for PDR; and study eye changes on the DRSS. RESULTS In the integrated FAME data set, compared with sham control-treated subjects, time to first PDR event was significantly delayed in subjects treated with FAc (P < 0.001), and this effect was confirmed in subgroups with more severe DR and chronic DME at baseline. In addition, subjects with retinal nonperfusion at baseline showed greater reduction in progression to PDR with FAc treatment. Both FAc dosages demonstrated statistically significant improvements in mean DR severity compared with sham treatment at months 6, 12, and 18. Numerically more subjects who received FAc experienced 2-or-more- or 3-or-more-step improvements in DR severity compared with subjects who received sham; conversely, fewer subjects treated with FAc experienced 2-or-more- or 3-or-more-step worsening in DR severity. The 3-or-more-step improvement with 0.5 μg/day FAc was statistically significantly different from sham control. CONCLUSIONS In subjects with DME, sustained intraocular delivery of FAc slows development of PDR and slows progression of diabetic retinopathy.

Abstract
BACKGROUND The idea that increasing salt intake increases drinking and urine volume is widely accepted. We tested the hypothesis that an increase in salt intake of 6 g/d would change fluid balance in men living under ultra-long-term controlled conditions. METHODS Over the course of 2 separate space flight simulation studies of 105 and 205 days' duration, we exposed 10 healthy men to 3 salt intake levels (12, 9, or 6 g/d). All other nutrients were maintained constant. We studied the effect of salt-driven changes in mineralocorticoid and glucocorticoid urinary excretion on day-to-day osmolyte and water balance. RESULTS A 6-g/d increase in salt intake increased urine osmolyte excretion, but reduced free-water clearance, indicating endogenous free water accrual by urine concentration. The resulting endogenous water surplus reduced fluid intake at the 12-g/d salt intake level. Across all 3 levels of salt intake, half-weekly and weekly rhythmical mineralocorticoid release promoted free water reabsorption via the renal concentration mechanism. Mineralocorticoid-coupled increases in free water reabsorption were counterbalanced by rhythmical glucocorticoid release, with excretion of endogenous osmolyte and water surplus by relative urine dilution. A 6-g/d increase in salt intake decreased the level of rhythmical mineralocorticoid release and elevated rhythmical glucocorticoid release. The projected effect of salt-driven hormone rhythm modulation corresponded well with the measured decrease in water intake and an increase in urine volume with surplus osmolyte excretion. CONCLUSION Humans regulate osmolyte and water balance by rhythmical mineralocorticoid and glucocorticoid release, endogenous accrual of surplus body water, and precise surplus excretion.
