Multiscale methods for shape constraints in deconvolution: Confidence statements for qualitative features

We derive multiscale statistics for deconvolution in order to detect qualitative features of the unknown density. An important example covered within this framework is to test for local monotonicity on all scales simultaneously. We investigate the moderately ill-posed setting, where the Fourier transform of the error density in the deconvolution model is of polynomial decay. For multiscale testing, we consider a calibration, motivated by the modulus of continuity of Brownian motion. We investigate the performance of our results from both the theoretical and simulation based point of view. A major consequence of our work is that the detection of qualitative features of a density in a deconvolution problem is a doable task, although the minimax rates for pointwise estimation are very slow.

Empfehlungen zur Diagnostik und Therapie der behavioralen und psychologischen Symptome der Demenz (BPSD)

In patients with dementia, Behavioral and Psychological Symptoms of Dementia (BPSD) are frequent findings that accompany deficits caused by cognitive impairment and thus complicate diagnostics, therapy and care. BPSD are a burden both for affected individuals as well as care-givers, and represent a significant challenge for therapy of a patient population with high degree of multi-morbidity. The goal of this therapy-guideline issued by swiss professional associations is to present guidance regarding therapy of BPSD as attendant symptoms in dementia, based on evidence as well as clinical experience. Here it appears to be of particular importance to take into account professional experience, as at this point for most therapeutic options no sufficiently controlled clinical trials are available. A critical discussion of pharmaco-therapeutic intervention is necessary, as this patient-population is particularly vulnerable for medication side-effects. Finally, a particular emphasis is placed on incorporating and systematically reporting psycho-social and nursing options therapeutic intervention.

The role of anti-VEGF agents in myopic choroidal neovascularization: Current standards and future outlook

Introduction The global prevalence of pathologic myopia is 0.9-3.1%, and visual impairment is found in 0.1-0.5% of European and 0.2-1.4% of Asian studies. Myopic choroidal neovascularization (mCNV) affects 5.2-11.3% of pathologic myopia patients and is a leading cause of vision impairment in the working-age population. Characteristic morphological changes and visual-acuity decrease are diagnostic features. Vascular-Endothelial-Growth-Factor (VEGF) has been identified as a trigger for pathologic neovascularization in these highly myopic patients. Areas Covered We cover the epidemiology, pathology and diagnostic aspects of mCNV. The history of therapeutic interventions is described, followed by an overview of current standard-of-care (SOC)-blocking VEGF using bevacizumab (off-label), ranibizumab or aflibercept and improving vision up to 13.5-14.4 letters. Despite good efficacy, an unmet medical need remains. We summarize ongoing and future developments of new drugs to treat or potentially cure mCNV. Expert Opinion mCNV is a major global health concern. Early detection and treatment is key for a satisfying outcome. The current SOC, VEGF inhibitors, affords good therapeutic efficacy and reasonable disease stabilization with few intravitreal treatments per year. However, the long-term prognosis is still unsatisfactory, and side-effects like chorioretinal atrophy development are of concern. Therefore, efforts should be intensified to develop more effective therapies.

Oral Lutein Supplementation Enhances Macular Pigment Density and Contrast Sensitivity but Not in Combination With Polyunsaturated Fatty Acids.

Purpose It has been shown that lutein and zeaxanthin accumulate in the macula where they enhance contrast sensitivity and may reduce the risk of progression to advanced age-related macular degeneration (AMD). Furthermore, omega-3 long-chain polyunsaturated fatty acids (PUFA) might further reduce this risk. However, controversy exists regarding whether PUFA may reduce the bioavailability of lutein. Methods This was a prospective 12-month, randomized, open label study evaluating the effect of supplementation with lutein, other antioxidants, and minerals on contrast sensitivity (CS) and macular pigment optical density (MPOD) in patients with age-related maculopathy. A total of 79 patients were randomized to either lutein (10 mg) and antioxidant supplement or lutein and antioxidant supplement in combination with PUFA. Patients received supplementation for a period of 6 months and were followed for a total of 12 months. Results Serum lutein and zeaxanthin increased significantly by the first follow-up visit at 1 month, and remained elevated throughout the intervention period of 6 months in the lutein-only group but not in the lutein+PUFA group. Macular pigment optical density and CS increased significantly in the lutein-only group (P < 0.005) but not in the lutein+PUFA group (P = 0.059) compared to baseline. Best-corrected visual acuity remained unchanged during the entire study period in both groups. Conclusions Addition of PUFA may reduce the bioavailability of lutein and therefore lessen the beneficial effect on macular pigment and CS. This needs to be considered when prescribing lutein supplements to patients with low lutein levels. (ClinicalTrials.gov number, NCT00563979.).

HLA-A29-POSITIVE BIRDSHOT CHORIORETINOPATHY IN AN AFRICAN AMERICAN PATIENT.

PURPOSE: To report the first documented case of HLA-A29-positive birdshot chorioretinopathy in an African American patient. METHODS: A 51-year-old African American woman presented with a 10-year history of photopsia, progressive decrease in visual acuity, metamorphopsia, and new nyctalopia. Both fundi showed evidence of periphlebitis, arterial attenuation, macular edema, and diffuse chorioretinal atrophy. RESULTS: Fluorescein angiography revealed diffuse vascular leakage, and indocyanine green showed evenly distributed and symmetrical hypofluorescent spots, which were difficult to appreciate on fundoscopy. Workup revealed a positive HLA-A29 and was negative for sarcoid, tuberculosis, and syphilis. CONCLUSION: Birdshot chorioretinopathy overwhelmingly affects non-Hispanic Caucasians, but there have been rare reported cases in other ethnicities including Hispanics and African Americans. This patient's ethnicity may have contributed to the 10-year delay in diagnosis. To our knowledge, this is the first documented HLA-A29 positive case of birdshot chorioretinopathy in an African American. HLA-A29 may be a useful supportive test in cases with classic clinical presentation in non-Caucasian patients to enable the correct diagnose in a timely manner.
