Quinoa Phenotyping Methodologies: An International Consensus
Quinoa is a crop originating in the Andes but grown more widely and with the genetic potential for significant further expansion. Due to the phenotypic plasticity of quinoa, varieties need to be assessed across years and multiple locations. To improve comparability among field trials
across the globe and to facilitate collaborations, components of the trials need to be kept consistent, including the type and methods of data collected. Here, an internationally open-access framework for phenotyping a wide range of quinoa features is proposed to facilitate the systematic agronomic, physiological and genetic characterization of quinoa for crop adaptation and improvement. Mature plant phenotyping is a central aspect of this paper, including detailed descriptions and the provision of phenotyping cards to facilitate consistency in data collection. High-throughput methods for multi-temporal phenotyping based on remote sensing technologies are described. Tools for higher throughput
post-harvest phenotyping of seeds are presented. A guideline for approaching quinoa field trials including the collection of environmental data and designing layouts with statistical robustness is suggested. To move towards developing resources for quinoa in line with major cereal
crops, a database was created. The Quinoa Germinate Platform will serve as a central repository of data for quinoa researchers globally
Functional impairment of systemic scleroderma patients with digital ulcerations: Results from the DUO registry
Demographic, clinical and antibody characteristics of patients with digital ulcers in systemic sclerosis: data from the DUO Registry
OBJECTIVES: The Digital Ulcers Outcome (DUO) Registry was designed to describe the clinical and antibody characteristics, disease course and outcomes of patients with digital ulcers associated with systemic sclerosis (SSc).
METHODS: The DUO Registry is a European, prospective, multicentre, observational, registry of SSc patients with ongoing digital ulcer disease, irrespective of treatment regimen. Data collected included demographics, SSc duration, SSc subset, internal organ manifestations, autoantibodies, previous and ongoing interventions and complications related to digital ulcers.
RESULTS: Up to 19 November 2010 a total of 2439 patients had enrolled into the registry. Most were classified as either limited cutaneous SSc (lcSSc; 52.2%) or diffuse cutaneous SSc (dcSSc; 36.9%). Digital ulcers developed earlier in patients with dcSSc compared with lcSSc. Almost all patients (95.7%) tested positive for antinuclear antibodies, 45.2% for anti-scleroderma-70 and 43.6% for anticentromere antibodies (ACA). The first digital ulcer in the anti-scleroderma-70-positive patient cohort occurred approximately 5 years earlier than the ACA-positive patient group.
CONCLUSIONS: This study provides data from a large cohort of SSc patients with a history of digital ulcers. The early occurrence and high frequency of digital ulcer complications are especially seen in patients with dcSSc and/or anti-scleroderma-70 antibodies

Cohort profile: Greifswald Approach to Individualized Medicine (GANI_MED)
BACKGROUND: Individualized Medicine aims at providing optimal treatment for an individual patient at a given time based on his specific genetic and molecular characteristics. This requires excellent clinical stratification of patients as well as the availability of genomic data and biomarkers as prerequisites for the development of novel diagnostic tools and therapeutic strategies. The University Medicine Greifswald, Germany, has launched the "Greifswald Approach to Individualized Medicine" (GANI_MED) project to address major challenges of Individualized Medicine. Herein, we describe the implementation of the scientific and clinical infrastructure that allows future translation of findings relevant to Individualized Medicine into clinical practice.Methods/design: Clinical patient cohorts (N < 5,000) with an emphasis on metabolic and cardiovascular diseases are being established following a standardized protocol for the assessment of medical history, laboratory biomarkers, and the collection of various biosamples for bio-banking purposes. A multi-omics based biomarker assessment including genome-wide genotyping, transcriptome, metabolome, and proteome analyses complements the multi-level approach of GANI_MED. Comparisons with the general background population as characterized by our Study of Health in Pomerania (SHIP) are performed. A central data management structure has been implemented to capture and integrate all relevant clinical data for research purposes. Ethical research projects on informed consent procedures, reporting of incidental findings, and economic evaluations were launched in parallel

Functional impairment of systemic scleroderma patients with digital ulcerations: results from the DUO Registry
Objective. Digital ulcers (DUs) are frequent manifestations of systemic
scleroderma (SSc). This study assessed functional limitations due to DUs
among patients enrolled in the Digital Ulcer Outcome (DUO) Registry, an
international, multicentre, observational registry of SSc patients with
DU disease.
Methods. Patients completed at enrolment a DU-specific functional
assessment questionnaire with a 1-month recall period, measuring
impairment in work and daily activities, and hours of help needed from
others. Physician-reported clinical parameters were used to describe the
population. For patients who completed at least part of the
questionnaire, descriptive analyses were performed for overall results,
and stratified by number of DUs at enrolment.
Results. This study included 2327 patients who completed at least part
of the questionnaire. For patients with 0, 1-2, and DUs at enrolment,
mean overall work impairment during the prior month among
employed/self-employed patients was 28\%, 42\%, and 48\%, respectively.
Across all included patients, ability to perform daily activities was
impaired on average by 35\%, 54\%, and 63\%, respectively. Patients
required a mean of 2.0, 8.7, and 8.8 hours of paid help and 17.0, 35.9,
and 63.7 hours of unpaid help, respectively, due to DUs in the prior
month. Patients with DUs had more complications and medication use than
patients with no DUs.
Conclusion. With increasing number of DUs, SSc patients reported more
impairment in work and daily activities and required more support from
others
