Self-reported sun exposure is commonly used in research, but how well this represents actual sun exposure is poorly understood. From February to July 2011, a volunteer sample (n = 47) of older adults (≥45 years) in Canberra, Australia, answered brief questions on time outdoors (weekdays and weekends) and natural skin color. They subsequently maintained a sun diary and wore an ultraviolet radiation (UVR) digital dosimeter for 7 days. Melanin density was estimated using reflectance spectrophotometry; lifetime sun damage was assessed using silicone casts of the back of the hand; and serum 25-hydroxyvitamin D (25(OH)D) concentration was assayed. Questionnaire-reported time outdoors correlated significantly with diary-recorded time outdoors (Spearman correlation r(s) = 0.66; 95% CI 0.46, 0.80; P < 0.001) and UVR dosimeter dose (r(s ) = 0.46; 95% CI 0.18, 0.68; P = 0.003), but not 25(OH)D concentration (r(s) = 0.24; 95% CI -0.05, 0.50; P = 0.10). Questionnaire-reported untanned skin color correlated significantly with measured melanin density at the inner upper arm (r(s) = 0.49; 95% CI 0.24, 0.68; P < 0.001). In a multiple linear regression model, statistically significant predictors of 25(OH)D concentration were self-reported frequency of physical activity, skin color and recent osteoporosis treatment (R(2) = 0.54). In this study, brief questionnaire items provided valid rankings of sun exposure and skin color, and enabled the development of a predictive model for 25(OH)D concentration.

Many initiatives have been developed to facilitate older adults' engagement in physical activity (PA) and document its benefits. One example is Texercise, a 12-week program with a focus on increasing participants' self-efficacy. The goal of this paper is to augment the knowledgebase of PA program implementation and dissemination by elucidating the experience of Texercise implementation as perceived by multiple stakeholders. We conducted 28 semistructured stakeholder interviews and categorized the responses into four preset themes: (1) program delivery and advocacy; (2) value/merit of the program; (3) successes/challenges of offering and sustaining the program; and (4) recommendations for enhancing implementation and delivery. We identified emergent subthemes through further analysis. Many perceptions that are broadly applicable to community organizations emerged. Our findings highlight the importance of stakeholder support when embedding PA programs in communities. Furthermore, the findings are crucial to understanding underlying processes that support widespread program dissemination and sustainability.

Veterinary paraprofessionals (VPPs) are engaged worldwide in animal health management, disease surveillance and food safety control. In many countries, particularly developing countries, VPPs are critical to national veterinary services provision. Until recently, there were no globally recognized training requirements for VPPs. Recognition of VPPs’ qualifications and roles, and requirements for registration, vary greatly between jurisdictions. To address these issues, the World Organisation for Animal Health (OIE) has developed competency and curricular guidelines for VPPs. A collaborative approach was essential to this mission. Extensive consultation with individuals and agencies representing various countries, animal health and veterinary sectors, and forms of expertise, was undertaken. Collaborative methods included the formation of a guidelines development ad hoc group whose diversity reflected project needs, the use of existing OIE Member Country data to understand roles of VPPs globally, conducting stakeholder surveys to collate VPP competency expectations and solicit feedback on draft guidelines, and in-country missions to validate draft curricular models. The initial deliverable from this work was publication of Competency Guidelines for VPPs. This document provides recommendations on the knowledge, skills, attitudes, and aptitudes that could be expected of VPPs following effective training. The companion document, OIE Curricular Guidelines for VPPs, provides recommendations on coursework structure and content to achieve these competencies. These guidelines will assist countries worldwide in more effectively training and qualifying VPPs so that they can contribute positively to the provision of veterinary services. Another potential impact is to catalyze the review of educational and regulatory standards regarding the respective work rights and activities of veterinarians and VPPs.

An innovative training program entitled “AgSecure Africa ProgrammeTM” was developed in partnership with the South African Agricultural Research Council-Onderstepoort Veterinary Research (ARC-OVR) to train veterinarians, animal health technicians, researchers and laboratory personnel. Three blended courses consisting of both virtual and in-person delivery were provided with the intent of contributing to the better prevention, detection and control of infectious diseases of livestock and poultry of significant importance for the region with a strong emphasis on transboundary animal diseases. A “train the trainer” model of instruction was employed to equip participants with the ability to train and share knowledge with colleagues and small-holder farmers in their various communities and regions. The design of this program was to increase the capacity of veterinarians and veterinary diagnosticians to safely and accurately diagnose infectious livestock diseases and to also empower small-holder farmers with the knowledge needed to safely and securely manage their livestock and be a first line defense in the prevention and control of infectious livestock diseases. Quantitative and qualitative evaluations were used to measure the impact of the trainings which revealed significant increases in knowledge gains. Course materials were submitted and approved for accreditation by the South African Veterinary Council (SAVC) becoming the first international training program to achieve this. Approval of these courses led to licensed veterinarians and animal health technicians being awarded continuing professional development credits upon their successful completion of courses. A larger goal was to build training capacity, not only for South Africa, but also for the region.
