RADIANCE: A Randomized Controlled Study of Ranibizumab in Patients with Choroidal Neovascularization Secondary to Pathologic Myopia.

OBJECTIVE To compare the efficacy and safety of ranibizumab 0.5 mg, guided by visual acuity (VA) stabilization or disease activity criteria, versus verteporfin photodynamic therapy (vPDT) in patients with visual impairment due to myopic choroidal neovascularization (CNV). DESIGN Phase III, 12-month, randomized, double-masked, multicenter, active-controlled study. PARTICIPANTS Patients (N = 277) with visual impairment due to myopic CNV. METHODS Patients were randomized to receive ranibizumab on day 1, month 1, and thereafter as needed guided by VA stabilization criteria (group I, n = 106); ranibizumab on day 1 and thereafter as needed guided by disease activity criteria (group II, n = 116); or vPDT on day 1 and disease activity treated with ranibizumab or vPDT at investigators' discretion from month 3 (group III, n = 55). MAIN OUTCOME MEASURES Mean average best-corrected visual acuity (BCVA) change from baseline to month 1 through months 3 (primary) and 6, mean BCVA change and safety over 12 months. RESULTS Ranibizumab treatment in groups I and II was superior to vPDT based on mean average BCVA change from baseline to month 1 through month 3 (group I: +10.5, group II: +10.6 vs. group III: +2.2 Early Treatment Diabetic Retinopathy Study [ETDRS] letters; both P< 0.0001). Ranibizumab treatment guided by disease activity was noninferior to VA stabilization-guided retreatment based on mean average BCVA change from baseline to month 1 through month 6 (group II: +11.7 vs. group I: +11.9 ETDRS letters; P< 0.00001). Mean BCVA change from baseline to month 12 was +13.8 (group I), +14.4 (group II), and +9.3 ETDRS letters (group III). At month 12, 63.8% to 65.7% of patients showed resolution of myopic CNV leakage. Patients received a median of 4.0 (group I) and 2.0 (groups II and III) ranibizumab injections over 12 months. No deaths or cases of endophthalmitis and myocardial infarction occurred. CONCLUSIONS Ranibizumab treatment, irrespective of retreatment criteria, provided superior BCVA gains versus vPDT up to month 3. Ranibizumab treatment guided by disease activity criteria was noninferior to VA stabilization criteria up to month 6. Over 12 months, individualized ranibizumab treatment was effective in improving and sustaining BCVA and was generally well tolerated in patients with myopic CNV.

Macular hole surgery in patients with end-stage choroideremia

OBJECTIVE To assess macular hole surgery in patients with end-stage choroideremia with regard to anatomic closure and visual outcome. DESIGN Retrospective, interventional case series. PARTICIPANTS Thirty adult male patients with a diagnosis of advanced choroideremia were reviewed and underwent spectral domain optical coherence tomography (OCT) as part of the screening process for a gene therapy clinical trial. From within that cohort, 3 were identified as having a full-thickness macular hole (FTMH). METHODS A 23-gauge pars plana vitrectomy was performed with peeling of the inner limiting membrane and gas tamponade. Preoperative best-corrected visual acuity ranged from perception of light to 6/24. MAIN OUTCOME MEASURES Prevalence of FTMH in advanced choroideremia, morphologic phenotype characteristics of FTMH in OCT, pre- and postoperative best-corrected visual acuity, and closure rate after surgery. RESULTS The prevalence of FTMH in advanced choroideremia in our cohort was 10%. One hole was associated with significant macular schisis, presumed to be attributable to degeneration of outer retinal layers. Anatomic closure was achieved in all 3 patients and confirmed with spectral domain OCT. Gas tamponade lasted approximately twice as long as might be expected compared with standard FTMH surgery. Objective visual acuity did not improve; however, perceived vision improved in all patients. CONCLUSIONS Although FTMH in choroideremia is a rare finding, it could potentially mask central progression of the disease. Regular screening may help to diagnose holes at an earlier stage when the visual prognosis after surgery may be better. Standard macular hole surgery seems to be effective in gaining anatomic closure, which would be significant for patients who subsequently require macula detachment for subretinal gene therapy.

Tools for better SLM knowledge management and informed decision-making in addressing land degradation at different scales: the WOCAT–LADA–DESIRE methodology

Desertification research conventionally focuses on the problem – that is, degradation – while neglecting the appraisal of successful conservation practices. Based on the premise that Sustainable Land Management (SLM) experiences are not sufficiently or comprehensively documented, evaluated, and shared, the World Overview of Conservation Approaches and Technologies (WOCAT) initiative (www.wocat.net), in collaboration with FAO’s Land Degradation Assessment in Drylands (LADA) project (www.fao.org/nr/lada/) and the EU’s DESIRE project (http://www.desire-project.eu/), has developed standardised tools and methods for compiling and evaluating the biophysical and socio-economic knowledge available about SLM. The tools allow SLM specialists to share their knowledge and assess the impact of SLM at the local, national, and global levels. As a whole, the WOCAT–LADA–DESIRE methodology comprises tools for documenting, self-evaluating, and assessing the impact of SLM practices, as well as for knowledge sharing and decision support in the field, at the planning level, and in scaling up identified good practices. SLM depends on flexibility and responsiveness to changing complex ecological and socioeconomic causes of land degradation. The WOCAT tools are designed to reflect and capture this capacity of SLM. In order to take account of new challenges and meet emerging needs of WOCAT users, the tools are constantly further developed and adapted. Recent enhancements include tools for improved data analysis (impact and cost/benefit), cross-scale mapping, climate change adaptation and disaster risk management, and easier reporting on SLM best practices to UNCCD and other national and international partners. Moreover, WOCAT has begun to give land users a voice by backing conventional documentation with video clips straight from the field. To promote the scaling up of SLM, WOCAT works with key institutions and partners at the local and national level, for example advisory services and implementation projects. Keywords: Sustainable Land Management (SLM), knowledge management, decision-making, WOCAT–LADA–DESIRE methodology.

Desertification mitigation and water harvesting based on sustainable land management

Traditionally, desertification research has focused on degradation assessments, whereas prevention and mitigation strategies have not sufficiently been emphasised, although the concept of sustainable land management (SLM) is increasingly being acknowledged. SLM strategies are interventions at the local to regional scale aiming at increasing productivity, protecting the natural resource base, and improving livelihoods. The global WOCAT initiative and its partners have developed harmonized frameworks to compile, evaluate and analyse the impact of SLM practices around the globe. Recent studies within the EU research project DESIRE developed a methodological framework that combines a collective learning and decision-making approach with use of best practices from the WOCAT database. In-depth assessment of 30 technologies and 8 approaches from 17 desertification sites enabled an evaluation of how SLM addresses prevalent dryland threats such as water scarcity, soil and vegetation degradation, low production, climate change, resource use conflicts and migration. Among the impacts attributed to the documented technologies, those mentioned most were diversified and enhanced production and better management of water and soil degradation, whether through water harvesting, improving soil moisture, or reducing runoff. Water harvesting offers under-exploited opportunities for the drylands and the predominantly rainfed farming systems of the developing world. Recently compiled guidelines introduce the concepts behind water harvesting and propose a harmonised classification system, followed by an assessment of suitability, adoption and up-scaling of practices. Case studies go from large-scale floodwater spreading that make alluvial plains cultivable, to systems that boost cereal production in small farms, as well as practices that collect and store water from household compounds. Once contextualized and set in appropriate institutional frameworks, they can form part of an overall adaptation strategy for land users. More field research is needed to reinforce expert assessments of SLM impacts and provide the necessary evidence-based rationale for investing in SLM. This includes developing methods to quantify and value ecosystem services, both on-site and off-site, and assess the resilience of SLM practices, as currently aimed at within the new EU CASCADE project.

Gutachten zu den ökologischen Anforderungen an das Inverkehrbringen von Produkten erstattet dem Bundesamt für Umwelt BAFU

Das schweizerische Verfassungsrecht belässt dem Gesetzgeber einen hinreichenden Spielraum, Massnahmen bezüglich der Inverkehrsetzung von importierten Produkten nach Massgabe von Anforderungen an die Produktionsbedingungen im Exportland (Production and Process Methods, PPMs) im Bereich der untersuchten Produkte (Palmöl, Soya, biogene Treibstoffe, Textilien, Baumwolle) im Rahmen eines Bundesgesetzes zu erlassen. Der Gestaltungsspielaum bemisst sich im einzelnen nach den detaillierten Bestimmungen des WTO Rechts. Dabei steht die Förderung freiwilliger Labels und von internationalen Standards für Best Practices im Vordergrund. Es schliesst indessen auch einseitige Import- restriktionen auf Grund von PPMs nicht aus, soweit vorgängig durchgeführte Verhand- lungen mit den Exportstaaten nicht zielführend sind und freiwillige Massnahmen nicht genügen. Das kann vor allem im Rohstoffhandel und im Konzernhandel (intrafirm trade) zutreffen. Die Regelungen unterliegen einer Verhältnismässigkeitsprüfung und sie dürfen sich nicht zum Schutze der einheimischen Industrie auswirken. Das GATT-recht erlaubt auch zollrechtliche Massnahmen als Mittel und Anreiz zur Förderung von Best Practices im Exportstaat. Das Freihandelsabkommen Schweiz-EU folgt den gleichen Grundsätzen, schliesst indessen zollrechtliche Massnahmen bezüglich der erfassten Produkte aus. Das Bundesgesetz über die Beseitigung technischer Handelshemmnisse verlangt die Anpassung an EU-rechtliche PPM Standards, soweit diese bestehen. Damit werden auch Spannungen im Rahmen des Freihandelsabkommens vermieden. Das THG erlaubt aber auch die ein- seitige Entwicklung von Best Practices und damit die Schaffung von Anreizen für die Ent- wicklung internationaler Standards. Das Cassis-de-Dijon Prinzip findet vorliegend keine unmittelbare Anwendung. Die hier behandelten Importregelungen beschränken sich auf die Rohstoffe und die unmittelbar daraus gewonnenen Basisprodukte. Sie lassen sich nicht auf verarbeitete Produkte übertragen. Diese können nur im Rahmen einer internationalen Harmonisierung miteinbezogen werden, welche alle Stufen der Verarbeitungsskette zu erfassen vermögen. Dies kann im Alleingang nicht erreicht werden.

Ökologische Anforderungen an das Inverkehrbringen von Produkten: USG-Revision und Spielräume im internationalen Recht

Der verfassungsrechtliche Spielraum des Gesetzgebers bei der Konkretisierung der Ziele der Nachhaltigkeit im Wirtschafts- und Umweltrecht wird in erster Linie durch die völkerrechtlichen Rahmenbedingungen der WTO sowie die Rechtsbeziehungen der Schweiz mit der EU definiert. Der vorliegende Beitrag behandelt die Frage, ob und inwieweit die Einfuhr von Rohstoffen und unmittelbar daraus gewonnenen Basisprodukten von einer nachhaltigen Produktionsweise im Ausland abhängig gemacht werden darf. Diese Thematik ist in der Umwelt- und Klimapolitik von zunehmender Bedeutung. Herstellungsverfahren und ihre Auswirkungen auf Mensch und Umwelt rücken in den Vordergrund. Der Beitrag zeigt auf, dass die Förderung von freiwilligen Labels und internationalen Standards für Best Practices zwar im Vordergrund steht, einseitige Importrestriktionen von Produkten anknüpfend am Kriterium von sog. PPM (Production and Process Methods) im Rahmen des WTO-Rechts jedoch nicht ausgeschlossen sind, sofern die Grundsätze der Nichtdiskriminierung sowie der Verhältnismässigkeit beachtet werden und vorgängig eine einvernehmliche Lösung mit dem Exportstaat angestrebt wird. Solche Importrestriktionen haben – nebst freiwilligen Massnahmen − als wichtige Instrumente der Umwelt- und Klimapolitik in der Rechtsprechung Anerkennung gefunden. Dies sowohl im Rahmen des Allgemeinen Zoll- und Handelsabkommens als auch des Abkommens zur Beseitigung technischer Handelshemmnisse. Bisher wenig genutzte Möglichkeiten, die Einfuhr zu begrenzen, bestehen darüber hinaus in der Zollpolitik für Produkte, die von ausserhalb des Europäischen Wirtschaftraumes eingeführt werden. Das Freihandelsabkommen zwischen der Schweiz und der EU folgt im Wesentlichen den gleichen Grundsätzen wie das WTO-Recht und lässt PPMs als Unterscheidungsmerkmale für an sich gleichartige Produkte ebenfalls grundsätzlich zu.

Prognostic significance of foveal capillary drop-out and previous panretinal photocoagulation for diabetic macular oedema treated with ranibizumab

AIMS To investigate the prognostic significance of macular capillary drop-out and previous panretinal laser photocoagulation in diabetic macular oedema treated with intravitreal ranibizumab. METHODS Retrospective observational case series. Treatment-naive patients with diabetic macular oedema that had been treated with intravitreal ranibizumab as per the RESTORE study protocol for at least 12 months were included. Some patients (n=15) had previous panretinal laser photocoagulation. Best-corrected visual acuity and central retina thickness were recorded monthly. The foveal avascular zone and the perifoveal capillaries were quantitatively and qualitatively assessed on fluorescein angiography on two occasions during the observational period. RESULTS From the 46 eyes (46 patients) in this study, 13 (28%) had evidence of perifoveal capillary drop-out. Central retinal thickness was significantly thinner at baseline (p=0.02) and throughout the study period in these eyes compared with those with normal perifoveal capillaries. Both groups responded with a significant gain of best-corrected visual acuity to ranibizumab treatment (7.6±3.3 and 6.3±1.3 ETDRS letters, respectively). Eyes with previous panretinal laser photocoagulation displayed a comparable final outcome regarding function and morphology, requiring a similar intensity of intravitreal injections. CONCLUSIONS Perifoveal capillary drop-out did not limit the gain of visual acuity from intravitreal ranibizumab treatment. The reduction of central retina thickness was similar to that seen in eyes with normal perifoveal capillaries. Central retinal thickness in eyes with perifoveal capillary drop-out was generally reduced. However, this did not affect their benefit from treatment. Ranibizumab did not increase the amount of perifoveal capillary loss.

Current State of Reporting Pain Outcomes in Cochrane Reviews of Chronic Musculoskeletal Pain Conditions and Considerations for an OMERACT Research Agenda.

OBJECTIVE To assess the current state of reporting of pain outcomes in Cochrane reviews on chronic musculoskeletal painful conditions and to elicit opinions of patients, healthcare practitioners, and methodologists on presenting pain outcomes to patients, clinicians, and policymakers. METHODS We identified all reviews in the Cochrane Library of chronic musculoskeletal pain conditions from Cochrane review groups (Back, Musculoskeletal, and Pain, Palliative, and Supportive Care) that contained a summary of findings (SoF) table. We extracted data on reported pain domains and instruments and conducted a survey and interviews on considerations for SoF tables (e.g., pain domains, presentation of results). RESULTS Fifty-seven SoF tables in 133 Cochrane reviews were eligible. SoF tables reported pain in 56/57, with all presenting results for pain intensity (20 different outcome instruments), pain interference in 8 SoF tables (5 different outcome instruments), and pain frequency in 1 multiple domain instrument. Other domains like pain quality or pain affect were not reported. From the survey and interviews [response rate 80% (36/45)], we derived 4 themes for a future research agenda: pain domains, considerations for assessing truth, discrimination, and feasibility; clinically important thresholds for responder analyses and presenting results; and establishing hierarchies of outcome instruments. CONCLUSION There is a lack of standardization in the domains of pain selected and the manner that pain outcomes are reported in SoF tables, hampering efforts to synthesize evidence. Future research should focus on the themes identified, building partnerships to achieve consensus and develop guidance on best practices for reporting pain outcomes.

Fluctuations in Pigment Epithelial Detachment and Retinal Fluid Using a Bimonthly Treatment Regimen with Aflibercept for Neovascular Age-Related Macular Degeneration

PURPOSE To assess the effect of a bimonthly treatment regimen with intravitreal aflibercept on retinal fluid and pigment epithelial detachment (PED) in patients with neovascular age-related macular degeneration (AMD). METHODS Twenty-six treatment-naive eyes of 26 patients with choroidal neovascularisation secondary to AMD were included. The patients received three initial monthly (mean 30 days) intravitreal injections of aflibercept followed by a bimonthly (mean 62 days) fixed regimen for a total of 1 year. Best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) measurements were recorded at monthly intervals. In addition, the presence of intraretinal fluid (IRF) or subretinal fluid (SRF) or a combination of both as well as serous and fibrovascular PEDs were assessed. RESULTS The mean patient age was 80 years (range 54-93). There were 14 male and 12 female patients. The mean gain in BCVA at 1 year was 9.3 letters (SEM ±3) with a mean reduction of the central retinal thickness of 154 µm (SEM ±50). After 3 monthly injections of aflibercept, there was resolution of IRF and SRF in 80% of the treated eyes; the amount of fluid increased at months 4, 6 and 8 with troughs in between. Whereas fibrovascular PEDs remained stable after the loading phase, serous PEDs displayed a seesaw pattern. Patients without retinal pigment epithelium (RPE) atrophy at the end of the 1-year period had significantly better BCVA compared to patients with RPE atrophy (p = 0.03). CONCLUSION Despite significant overall BCVA gain, bimonthly intervals seem insufficient to maintain the morphological improvements after the initial loading dose with intravitreal aflibercept.

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.).

Sharing evidence of sustainable land management impacts

Ensuring sustainable use of natural resources is crucial for maintaining the basis for our livelihoods. With threats from climate change, disputes over water, biodiversity loss, competing claims on land, and migration increasing worldwide, the demands for sustainable land management (SLM) practices will only increase in the future. For years already, various national and international organizations (GOs, NGOs, donors, research institutes, etc.) have been working on alternative forms of land management. And numerous land users worldwide – especially small farmers – have been testing, adapting, and refining new and better ways of managing land. All too often, however, the resulting SLM knowledge has not been sufficiently evaluated, documented and shared. Among other things, this has often prevented valuable SLM knowledge from being channelled into evidence-based decision-making processes. Indeed, proper knowledge management is crucial for SLM to reach its full potential. Since more than 20 years, the international WOCAT network documents and promotes SLM through its global platform. As a whole, the WOCAT methodology comprises tools for documenting, evaluating, and assessing the impact of SLM practices, as well as for knowledge sharing, analysis and use for decision support in the field, at the planning level, and in scaling up identified good practices. In early 2014, WOCAT’s growth and ongoing improvement culminated in its being officially recognized by the UNCCD as the primary recommended database for SLM best practices. Over the years, the WOCAT network confirmed that SLM helps to prevent desertification, to increase biodiversity, enhance food security and to make people less vulnerable to the effects of climate variability and change. In addi- tion, it plays an important role in mitigating climate change through improving soil organic matter and increasing vegetation cover. In-depth assessments of SLM practices from desertification sites enabled an evaluation of how SLM addresses prevalent dryland threats. The impacts mentioned most were diversified and enhanced production and better management of water and soil degradation, whether through water harvesting, improving soil moisture, or reducing runoff. Among others, favourable local-scale cost-benefit relationships of SLM practices play a crucial role in their adoption. An economic analysis from the WOCAT database showed that land users perceive a large majority of the technologies as having benefits that outweigh costs in the long term. The high investment costs associated with some practices may constitute a barrier to adoption, however, where appropriate, short-term support for land users can help to promote these practices. The increased global concerns on climate change, disaster risks and food security redirect attention to, and trigger more funds for SLM. To provide the necessary evidence-based rationale for investing in SLM and to reinforce expert and land users assessments of SLM impacts, more field research using inter- and transdisciplinary approaches is needed. This includes developing methods to quantify and value ecosystem services, both on-site and off-site, and assess the resilience of SLM practices, as currently aimed at within the EU FP7 projects CASCADE and RECARE.
