Purpose: There are currently limited treatment options for aniridia. In this context, 3D printed iris implants may provide a cost-effective, cosmetically acceptable alternative for patients with aniridia. The purpose of this study was to develop a proof-of-concept workflow for manufacturing 3D printed iris implants using a silicone ink palette that aesthetically matches iris shades, identified in slit lamp images., Methods: Slit lamp iris photos from 11 healthy volunteers (3 green; 4 blue; 4 brown) were processed using k-means binning analyses to identify two or three prominent colors each. Candidate silicone inks were created by precisely combining pigments. A crowdsourcing survey software was used to determine color matches between the silicone ink swatches and three prominent iris color swatches in 2 qualifying and 11 experimental workflows., Results: In total, 54 candidate silicone inks (20 brown; 16 green; 18 blue) were developed and analyzed. Survey answers from 29 individuals that had passed the qualifying workflow were invited to identify "best matches" between the prominent iris colors and the silicone inks. From this color-match data, brown, blue, and green prototype artificial irises were printed with the silicone ink that aesthetically matched the three prominent colors. The iris was printed using a simplified three-layer five-branch starburst design at scale (12.8 mm base disc, with 3.5 mm pupil)., Conclusions: This proof-of-concept workflow produced color-matched silicone prosthetic irises at scale from a panel of silicone inks using prominent iris colors extracted from slit lamp images. Future work will include printing a more intricate iris crypt design and testing for biocompatibility.

The eye and the kidney share structural and developmental similarities on a cellular and clinical level, and they are often affected by the same disease processes. Performing an eye exam to look for signs of conditions such as hypertension and diabetes can provide a helpful window into the health of the kidney. Patients with kidney transplants (KT) are a unique population that require close monitoring. These patients are maintained on a number of immunosuppressive medications and may face complications such as medication side effects, infections, and graft rejection. Patients with KT are at higher risk of both infectious and noninfectious eye conditions related to underlying systemic disease or use of immunosuppressive medications. Screening for eye conditions is important because preserving visual function is integral to quality of life, and also because the eye exam can help with early detection and treatment of systemic conditions. Here we describe some of the common eye findings and conditions in patients with KT. We recommend that patients with KT receive annual eye exams, and we hope that the information provided here can help nephrologists become more familiar with eye findings and identify situations where a referral to ophthalmology is warranted., (Copyright © 2022 Elsevier Inc.

Prcis: Among patients with glaucoma or ocular hypertension, ineffective self-instillation of eye drops was associated with an increased long-term risk of progression or advancement of treatment to incisional surgery., Purpose: The purpose of this study was to evaluate the association between the efficacy of self-instillation of eye drops and long-term glaucoma outcomes., Methods: In a previous study, video recordings of eye drop self-instillation by patients with glaucoma or ocular hypertension were graded as effective or ineffective depending on whether the patient successfully instilled at least 1 drop on the right ocular surface. Glaucomatous progression was then retrospectively defined as retinal nerve fiber layer thinning as measured by either optical coherence tomography, visual field progression, or need for incisional glaucoma surgery as determined by a glaucoma specialist unaware of patient performance in the eye drop instillation study. Subjects with at least 2 follow-up optical coherence tomography or visual field studies were included in the current study., Results: The original study enrolled 119 patients. Sufficient follow-up data were available for 101 patients. Eighty-eight patients (87.1%) were effective in eye drop instillation at baseline. Mean follow-up was 5.1 years, during which time 73 patients (72.3%) had progression or underwent incisional surgery in either eye. A significantly higher proportion of patients in the ineffective group met the criteria for progression or underwent incisional surgery (effective: 68.2%; ineffective: 100%; N=101; P=0.017, Fisher exact test). Kaplan-Meier survival analyses showed a significantly faster time to reaching an endpoint in the ineffective group (N=101; P=0.012, log-rank test). There was no difference in age, baseline intraocular pressure, or baseline retinal nerve fiber layer thickness between the groups., Conclusion: Ineffective self-installation of eye drops was associated with an increased risk of glaucoma progression or treatment advancement to incisional surgery., Competing Interests: Disclosure: A.P.T. serves as a consultant at Ivantis, Sandoz, Zeiss.

Purpose: To evaluate the effectiveness of netarsudil in combination with other ocular hypotensive agents in patients with open-angle glaucoma (OAG) or ocular hypertension (OHT)., Design: Retrospective cohort study., Participants: All patients with OAG or OHT with netarsudil added to a regimen of at least 1 other ocular hypotensive agent between March 2018 and March 2019., Methods: Subjects with at least 2 baseline intraocular pressure (IOP) measurements on the same medication regimen before initiation of netarsudil were included. Subjects were excluded if they experienced other changes in their ocular hypotensive medication regimen., Main Outcome Measures: Change in IOP after initiation of netarsudil was assessed using linear mixed-effect models. Kaplan-Meier survival analysis was used to evaluate the time to discontinuation of netarsudil for any reason., Results: Netarsudil was prescribed for 191 eyes of 138 patients. All of these subjects were included in the analysis of adverse effects. Twelve subjects discontinued netarsudil before the first follow-up visit because of adverse effects, leaving 175 eyes of 126 patients with at least 1 follow-up visit while using netarsudil included in the effectiveness analysis. The mean baseline IOP ± standard deviation was 17.1 ± 5.2 mmHg on a median of 2 ocular hypotensive medications. Including all observations on the same medication regimen after the addition of netarsudil, the mean IOP was 15.0 ± 4.5 mmHg, with a mean reduction of 2.2 mmHg (P < 0.001). A reduction in IOP was observed in eyes on 1 (2.0 mmHg, P < 0.001), 2 (1.0 mmHg, P = 0.12), 3 (3.0 mmHg, P < 0.001), and 4 (2.9 mmHg, P = 0.002) medications at baseline. A sustained ≥ 20% IOP reduction was observed in 16.2% of 123 eyes with at least 2 observations on treatment with netarsudil. Of the 138 subjects who were treated with netarsudil, 26.8% discontinued it because of adverse effects. The median time to discontinuation of netarsudil for any reason was 88 days., Conclusions: This study demonstrates a modest reduction in IOP is achievable with netarsudil in patients with OAG or OHT who are taking as many as 4 ocular hypotensive medications. The incidence of discontinuation due to adverse effects or inadequate efficacy was high., (Copyright © 2021 American Academy of Ophthalmology. Published by Elsevier Inc. All rights reserved.)

Purpose of Review: Perimetry remains important for the diagnosis and management of glaucoma despite advances in imaging technology. The purpose of this review is to describe advances in the acquisition and analysis of visual field data and highlight novel techniques for performing perimetry., Recent Findings: Studies have focused on improving the detection of patients at highest risk of severe vision loss and the development of innovative testing strategies that allow for more frequent testing. Artificial intelligence has been utilized in research settings to improve detection and characterization of glaucomatous field damage. Furthermore, tablet-based strategies and virtual reality headsets show promise for glaucoma screening and remote monitoring of patients with glaucoma., Summary: New testing strategies and research findings have improved our ability to identify patients with both paracentral and mid-peripheral visual field progression. New strategies have the potential to make visual field testing more efficient, reliable and accessible for patients with glaucoma., (Copyright © 2021 Wolters Kluwer Health, Inc.

Introduction: Social determinants of health (SDH) may influence inpatient utilization rates and outcomes but have yet to be associated with ocular diagnoses. The purpose of this paper was to determine whether the SDH are associated with ocular hospitalizations., Methods: Patients from the national Medicare 100% Inpatient Limited Dataset were examined and linked to SDH measures from the Robert Wood Johnson Foundation (RWJF) County Health Rankings. Patients were included in the study group with either an admitting or primary diagnosis of an ophthalmic condition. All other hospitalized Medicare patients served in the comparison group. Nested logistic regression of these Medicare patients was conducted in their respective communities at the county level. SDH measures were benchmarked above or below the national median., Results: Positively associated SDH factors included communities with air pollution exceeding 11.62 micro grams per cubic meter (OR 1.05; 95% CI 1.01-1.08), communities where severe housing problems exceeding 14.38% (OR 1.13; 95% CI 1.09-1.18), children in single parent households exceeding 32.13% (OR 1.06; 95% CI 1.02-1.11), violent crime rate exceeding 250.54 per 100,000 (OR 1.07; 95% CI 1.03-1.12), diabetes exceeding 10.95% (OR 1.09: 95% CI 1.04-1.14), and drug poisoning deaths including opioids exceeding 14.17 per 100,000 (OR 1.04; 95% CI 1.01-1.08)., Conclusion: When compared to an all-condition, hospitalized population, ocular hospitalizations tended to have small, yet statistically significant associations with health behaviors, socioeconomic, and physical environment factors. Further research will be needed on how the physical environment, social, and community variables affect ocular health relative to all-cause hospitalizations.

This is the first case of histopathologically proven blastomycosis involving the lacrimal gland. A 51-year-old woman with a history of disseminated blastomycosis involving her lungs and skin, on oral itraconazole, presented with 3 days of right upper eyelid swelling, erythema, and pain concerning for recurrent dacryoadenitis. MRI showed enlargement of the right lacrimal gland with a cystic lesion at the anterior aspect of the gland with a radiographic differential diagnosis of abscess versus cyst. After no improvement with intravenous antibiotics, orbitotomy with lacrimal gland biopsy and incision and drainage of the cystic lesion were performed. Culture and pathology of the drained fluid demonstrated an abscess with both viable and nonviable broad-based budding yeast consistent with partially treated blastomycosis. The patient's symptoms improved after the surgery and continued itraconazole therapy.

Purpose: To study the characteristics of Medicare beneficiaries hospitalized for ophthalmic conditions., Design: Cross-sectional study., Methods: The 2015 National Medicare 100% Inpatient Limited Dataset was analyzed to identify all patients with either an admitting or primary diagnosis for an ophthalmic condition using ICD-9-CM codes. All other hospitalized Medicare patients served for comparison. Comorbidities were calculated using the Elixhauser Comorbidity Index. Multivariable logistic regression was used to determine odds of primary ophthalmic hospitalization after controlling for patient characteristics and medical comorbidities., Results: For 2015, there were a total of 13 152 Medicare patients with ocular hospitalizations compared to 6 621 005 patients with nonophthalmic events. Most ophthalmic patients were emergent admissions (73.19%) with routine discharges (75.50%) and low rates of inpatient mortality (0.62%). The top admitting diagnoses for nontraumatic and traumatic eye conditions were diplopia (11.69%) and closed fracture of the orbital floor (3.76%), respectively. Patients admitted for eye conditions were more likely to be younger, to be African American, and to have hypertension, valvular heart disease, diabetes, hypothyroidism, AIDS, lymphoma, solid tumor without metastasis, rheumatologic diseases, alcohol and drug abuse, psychoses, and depression compared to the general Medicare inpatient population., Conclusions: Most inpatient admissions for US Medicare beneficiaries with primary ophthalmic diagnoses were for nontraumatic disorders of the eye and adnexa. Ophthalmic admissions were on average shorter in duration and had lower rates of inpatient mortality compared to nonophthalmic admissions. Patients admitted for eye conditions were more likely to have comorbidities such as hypertension, diabetes, and depression compared to the general Medicare inpatient population., (Copyright © 2018 Elsevier Inc.

Multifocal uveal melanomas are extremely rare. In this case report, we describe a patient with 2 independent uveal melanomas in the same eye. A 52-year-old woman presented with a large choroidal melanoma and a smaller ciliary body mass, clinically thought to be a nevus, in her left eye. Enucleated specimen showed 2 primary lesions that were anatomically separate. Lesion 1 was a melanoma and lesion 2 was a melanoma arising centrally from a nevus. Both lesions harbored GNAQ mutations. This patient had no family history of uveal melanomas or signs of ocular melanocytosis and was negative for the BAP1 mutation. This case demonstrates how multifocal uveal melanomas can arise in patients who lack genetic predisposition for the disease. Furthermore, this case is one of the few that have shown, histopathologically, a small focus of malignant cells developing from a benign population within a nevus, which highlights the importance of closely monitoring nevi for signs of malignancy.

Conjunctival amyloidosis is a rare cause of ocular inflammation, mass, and hemorrhage that can be difficult to diagnose and treat. In this case series, we describe 4 patients with a histopathological diagnosis of conjunctival amyloidosis treated at a single institution. All patients underwent surgical excision and biopsy. On histopathological examination, 3 patients had local deposition of either kappa or lambda monoclonal immunoglobulin light chains, favoring localized amyloid light-chain amyloidosis. Systemic workup to exclude rheumatologic disorders (e.g., anti-neutrophil cytoplasmic antibody and rheumatoid factors) and hematological disorders (e.g., imaging, biopsies, and serum protein electrophoresis/urine protein electrophoresis) was negative except for a positive abdominal fat biopsy in 1 patient. Patients were followed for an average of 6.1 years (range 4 months to 15 years) with stable ocular disease.

Importance: Recent evidence supports the presence of macular damage (within 8° of the central field) to retinal ganglion cells and associated central visual field (VF) defects in glaucoma, even in early stages. Despite this, to our knowledge, the association of 10-2 VF damage with vision-related quality of life (QOL) has not been well studied., Objective: To determine the association between QOL and visual function as measured by 24-2 and 10-2 VFs in patients with primary open-angle glaucoma and to test the hypothesis that patients with vision-related QOL disproportionate to their 24-2 VF status may exhibit 10-2 damage overlooked by the 24-2 test., Design, Setting, and Participants: In this cross-sectional analysis of observational cohort study data taken from a tertiary care specialty practice, 113 patients with glaucoma with the entire range of 24-2 VF damage completed the National Eye Institute Visual Function Questionnaire (NEI VFQ-25). Data were collected from May 2014 to January 2015 and were analyzed from March 2016 to May 2016., Interventions: Standardized binocular 24-2 and 10-2 VF sensitivities were calculated for each patient., Main Outcomes and Measures: Association of binocular 24-2 and 10-2 VF sensitivity with Rasch-calibrated NEI VFQ-25 scores. Detection of outliers was based on Cook distance of the regression of binocular 24-2 and NEI VFQ-25 score. Outlier association with QOL was then assessed using a linear regression model, with binocular 10-2 VF sensitivity as the independent variable., Results: Of the 113 patients, the mean (SD) age was 70.1 (10.9) years, and 51 (45.1%) were male and 71 (62.8%) were white. The composite NEI VFQ-25 score was associated with both binocular 24-2 (β = 1.95; 95% CI, 0.47-3.43; P = .01) and 10-2 (β = 2.57; 95% CI, 1.12-4.01; P = .001) sensitivities, but the 10-2 VF univariable model showed an almost 2-fold better fit to the data (R2 = 9.2% vs 4.9%). However, the binocular 10-2 sensitivities of 24-2 outliers had the strongest association with the composite NEI VFQ-25 scores (β = 2.78; 95% CI, 0.84-4.72; P = .006.) and the best fit to the data (R2 = 18.2%.)., Conclusions and Relevance: The 10-2 VF model showed a stronger association with NEI VFQ-25 score than the 24-2 VF model. Patients with disproportionately low quality of vision relative to patients with 24-2 VF damage may have damage on the central field missed by the 24-2 grid. Future prospective testing, including additional dimensions of quality of life, is indicated.

Importance: Little is known about the association between structural macular damage and self-reported visual function of people with glaucoma., Objective: To determine the association between vision-related quality of life among patients with primary open-angle glaucoma with structural macular retinal ganglion cell plus inner plexiform layer (RGC+IPL) loss identified by spectral-domain optical coherence tomography (SD-OCT) machine-generated deviation maps and thickness measurements., Design, Setting, and Participants: This cross-sectional prospective study was conducted from March 1, 2014, to March 30, 2015, at the Department of Ophthalmology at Columbia University Medical Center. The participants were 107 patients who were enrolled in the study and represented the entire range of glaucomatous damage. All 214 eyes of the 107 participants underwent 10-2 visual field tests and SD-OCT scans, and all participants completed the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25). They also received ophthalmologic examination, including medical history review, best-corrected visual acuity, slitlamp biomicroscopy, intraocular pressure measurement, gonioscopy, dilated ophthalmoscopy, and standard automated perimetry. Macular RGC+IPL loss was determined by diffuse or focal patterns on SD-OCT-generated deviation maps (probability map that compared patients with aged-matched normative database) and thickness measurements., Main Outcomes and Measures: Regression analyses to assess the association of NEI VFQ-25 scores (score range: 41.9-99.5; higher scores indicate better functioning) with patterns of RGC+IPL loss and with RGC+IPL thickness measurements., Results: Of the 107 patients, 48 (45%) were men and the mean (SD) age was 65 (11) years. The self-reported race/ethnicity of participants consisted of 45 (46%) black, 47 (48%) white, and 6 (6%) "other" individuals. In the univariable analyses, patients with diffuse macular RGC+IPL loss had mean composite Rasch-calibrated NEI VFQ-25 scores that were 6.15 points lower than the scores of patients with focal damage (β = -6.15; 95% CI, -11.7 to -0.59; P = .03). The effect remained significant even after controlling for mean RGC+IPL thickness (β = -7.64; 95% CI, -14.2 to -1.03; P = .02)., Conclusions and Relevance: Characteristic patterns of glaucoma-related macular RGC+IPL loss appeared to be more important predictors of vision-related quality of life than thickness measures, with diffuse RGC+IPL loss as an indicator for diminished vision-related quality of life.

Importance: The effect of glaucoma on nonglaucomatous medical conditions and resultant secondary health care costs is not well understood., Objective: To assess self-reported medical conditions, the use of medical services, and total health care costs among Medicare beneficiaries with glaucoma., Design, Setting, and Participants: Longitudinal observational study of 72,587 Medicare beneficiaries in the general community using the Medicare Current Beneficiary Survey (2004-2009). Coding to extract data started in January 2015, and analyses were performed between May and July 2015., Main Outcomes and Measures: Self-reported health, the use of health care services, adjusted mean annual total health care costs per person, and adjusted mean annual nonoutpatient costs per person., Results: Participants were 72,587 Medicare beneficiaries 65 years or older with (n = 4441) and without (n = 68,146) a glaucoma diagnosis in the year before collection of survey data. Their mean age was 76.9 years, and 43.2% were male. Patients with glaucoma who responded to survey questions on visual disability were stratified into those with (n = 1748) and without (n = 2639) self-reported visual disability. Medicare beneficiaries with glaucoma had higher adjusted odds of inpatient hospitalizations (odds ratio [OR], 1.27; 95% CI, 1.17-1.39; P < .001) and home health aide visits (OR, 1.27; 95% CI, 1.13-1.43; P < .001) compared with Medicare beneficiaries without glaucoma. Furthermore, patients with glaucoma with self-reported visual disability were more likely to report depression (OR, 1.47; 95% CI, 1.26-1.71; P < .001), falls (OR, 1.34; 95% CI, 1.09-1.66; P = .006), and difficulty walking (OR, 1.22; 95% CI, 1.02-1.45; P = .03) compared with those without self-reported visual disability. In the risk-adjusted model, Medicare beneficiaries with glaucoma incurred an additional $2903 (95% CI, $2247-$3558; P < .001) annual total health care costs and $2599 (95% CI, $1985-$3212; P < .001) higher costs for nonoutpatient services compared with Medicare beneficiaries without glaucoma., Conclusions and Relevance: Glaucoma is associated with greater use of inpatient and home health aide services and with higher annual total and nonoutpatient medical costs. Perception of vision loss among patients with glaucoma may be associated with depression, falls, and difficulty walking. Reducing the prevalence and severity of glaucoma may result in improvements in associated nonglaucomatous medical conditions and resultant reduction in health care costs.

Importance: It is important to understand in more detail how patients with glaucoma were affected by the implementation of Medicare Part D, which was designed to provide beneficiaries with near-universal prescription drug coverage., Objectives: To determine changes in prescription drug coverage and out-of-pocket spending after the implementation of Medicare Part D across income strata and to identify characteristics of beneficiaries associated with prescription status., Design, Setting, and Participants: Longitudinal observational study in the general community using the Medicare Current Beneficiary Survey (pooled 2004, 2005, 2007, and 2008 data). Participants were noninstitutionalized Medicare beneficiaries who filled at least 1 glaucoma prescription during the survey years. The dates of this analysis were January 2004 to December 2009., Main Outcomes and Measures: Effect of the implementation of the Medicare Part D drug benefit, including prescription drug coverage and risk-adjusted out-of-pocket spending related to glaucoma medications., Results: Respondents included 12,079 participants in the 2004 survey, 11,089 participants in the 2005 survey, 11,995 participants in the 2007 survey, and 11,723 participants in the 2008 survey. The sample included 19,045 glaucoma prescriptions, and 2519 Medicare beneficiaries filled at least 1 glaucoma prescription during the study years. Overall 574 (22.8%) beneficiaries reported living below the poverty level, and 795 (31.6%) had incomes consistent with near-poor status. The implementation of Medicare Part D resulted in increased rates of prescription drug coverage across all economic strata, with reductions in beneficiaries without coverage from 22.8% to 4.0%, 29.1% to 7.3%, and 19.9% to 3.7% among poor, near-poor, and higher-income beneficiaries, respectively. Despite these gains, near-poor status remained a risk factor for lack of prescription drug coverage after the implementation of Medicare Part D (odds ratio, 2.46; 95% CI, 1.26-4.55; P = .04). No differences were identified in adjusted out-of-pocket prescriptions drug costs between the near poor and those with higher income, although out-of-pocket costs were 37% (95% CI, 26%-49%; P < .001) lower among the poor relative to those with higher income., Conclusions and Relevance: Medicare Part D enrolled most beneficiaries with glaucoma who previously lacked prescription drug coverage. The results of this study suggest that coverage gains lagged among the near poor. While these data evaluated changes in coverage among cohorts of beneficiaries and not from longitudinal follow-up of patients, targeted efforts to improve prescription drug coverage among vulnerable beneficiaries would likely improve access to prescribed ocular hypotensive medications.

Importance: Understanding factors that lead to nonadherence to glaucoma treatment is important to diminish glaucoma-related disability., Objectives: To determine whether the implementation of the Medicare Part D prescription drug benefit affected rates of cost-related nonadherence and cost-reduction strategies in Medicare beneficiaries with and without glaucoma and to evaluate associated risk factors for such nonadherence., Design, Setting, and Participants: Serial cross-sectional study using 2004 to 2009 Medicare Current Beneficiary Survey data linked with Medicare claims. Coding to extract data started in January 2014 and analyses were performed between September and November of 2014. Participants were all Medicare beneficiaries, including those with a glaucoma-related diagnosis in the year prior to the collection of the survey data, those with a nonglaucomatous ophthalmic diagnosis in the year prior to the collection of the survey data, and those without a recent eye care professional claim., Intervention: Effect of the implementation of the Medicare Part D drug benefit., Main Outcomes and Measures: The change in cost-related nonadherence and the change in cost-reduction strategies., Results: Between 2004 and 2009, the number of Medicare beneficiaries with glaucoma who reported taking smaller doses and skipping doses owing to cost dropped from 9.4% and 8.2% to 2.7% (P < .001) and 2.8%, respectively (P = .001). However, reports of failure to obtain prescriptions owing to cost did not improve in the same period (3.4% in 2004 and 2.1% in 2009; P = .12). After Part D, patients with glaucoma had a decrease in several cost-reduction strategies, namely price shopping (26.2%-15.2%; P < .001), purchasing outside the United States (6.9%-1.3%; P < .001), and spending less money to save for medications (8.0% to 3.5%; P < .001). Using a multivariate analysis, the main independent risk factors common to all cost-related nonadherence measures were female sex, younger age, lower income (<$30 000), self-reported visual disability, and a smaller Lawton index., Conclusions and Relevance: After the implementation of Part D, there was a decrease in the rate that beneficiaries with glaucoma reported engaging in cost-saving measures. Although there was a decline in the rate of several cost-related nonadherence behaviors, patients reporting failure to fill prescriptions owing to cost remained stable. This suggests that efforts to improve cost-related nonadherence should focus both on financial hardship and medical therapy prioritization, particularly in certain high-risk sociodemographic groups.

Background and Purpose: Treatment-related changes and recurrent tumors often have overlapping features on conventional MR imaging. The purpose of this study was to assess the utility of DWI and DSC perfusion imaging alone and in combination to differentiate treatment-related effects and recurrent high-grade gliomas., Materials and Methods: We retrospectively identified 68 consecutive patients with high-grade gliomas treated by surgical resection followed by radiation therapy and temozolomide, who then developed increasing enhancing mass lesions indeterminate for treatment-related changes versus recurrent tumor. All lesions were diagnosed by histopathology at repeat surgical resection. ROI analysis was performed of the enhancing lesion on the ADC and DSC maps. Measurements made by a 2D ROI of the enhancing lesion on a single slice were recorded as ADCLesion and rCBVLesion, and measurements made by the most abnormal small fixed diameter ROI as ADCROI and rCBVROI. Statistical analysis was performed with Wilcoxon rank sum tests with P = .05., Results: Ten of the 68 patients (14.7%) had treatment-related changes, while 58 patients (85.3%) had recurrent tumor only (n = 19) or recurrent tumor mixed with treatment effect (n = 39). DWI analysis showed higher ADCLesion in treatment-related changes than in recurrent tumor (P = .003). DSC analysis revealed lower relative cerebral blood volume (rCBV)Lesion and rCBVROI in treatment-related changes (P = .003 and P = .011, respectively). Subanalysis of patients with suspected pseudoprogression also revealed higher ADCLesion (P = .001) and lower rCBVLesion (P = .028) and rCBVROI (P = .032) in treatment-related changes. Applying a combined ADCLesion and rCBVLesion model did not outperform either the ADC or rCBV metric alone., Conclusions: Treatment-related changes showed higher diffusion and lower perfusion than recurrent tumor. Similar correlations were found for patients with suspected pseudoprogression., (© 2015 by American Journal of Neuroradiology.)

Aim: Serum PSA screening for prostate cancer (PCa) is controversial. Here, we identify three urinary biomarkers - aHGF, IGFBP3 and OPN - for PCa screening and prognostication., Methods: Urinary aHGF, OPN and IGFBP3 from healthy men (n = 19) and men with localized (n = 65) and metastatic (n = 36) PCa were quantified via ELISA. Mann-Whitney nonparametric t-test and the Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) analyses were used to analyze associations., Results: Mean aHGF and IGFBP3 levels were significantly elevated in PCa patients versus controls (p = 0.0006 and p = 0.0012, respectively), and the area under the curve of the receiver operating characteristic curve (indicator of diagnostic accuracy) for aHGF and IGFBP3 was 0.75 and 0.74, respectively. OPN levels were significantly higher in metastatic groups (p = 0.0060) versus localized and controls (area under the curve = 0.68)., Conclusion: Urinary aHGF and IGFBP3 exhibit the capacity for diagnostic discrimination for PCa, whereas OPN may indicate presence of metastatic disease.
