Abstract To control the health impact of the COVID-19 pandemic, governments implemented various restrictive policies, such as stay-at-home orders and restrictions on internal movement, which had adverse effects on consumption and, consequently, on international trade. This was observed even for products intensively traded and minimally impacted in terms of production, such as wine. Thus, to work towards a better awareness of future crises, this study assesses the impact of government policy responses to COVID-19 on the international wine trade. A gravity model, a benchmark approach for studying the determinants of trade, is estimated using monthly data for 20 exporting countries and 214 potential importing countries. The findings suggest that, ceteris paribus, the value of wine export flows was inversely related to the intensity of government policy response in importing countries due to lower demand provoked by restrictive measures. This effect was considerably reduced, however, concerning wines coming from the Old World, which are inferred to be more resilient, a factor primarily attributed to their higher share of wines exported with geographical indications. On the other hand, only the exports from Old World countries were negatively influenced by restrictions on internal movements in the exporting country, which reflects a business model with a complex supply chain in which several intermediaries are involved, thus weakening the direct linkage between wine producers and consumers.

Abstract Ultrasound elastography (USE) is a recent technology that has experienced major developments in the past two decades. The assessment of the main mechanical properties of tissues can be made with this technology by characterisation of their response to stress. This article reviews the two major techniques used in musculoskeletal elastography, compression elastography (CE) and shear-wave elastography (SWE), and evaluates the studies published on major electronic databases that use both techniques in the context of tendon pathology. CE accounts for more studies than SWE. The mechanical properties of tendons, particularly their stiffness, may be altered in the presence of tendon injury. CE and SWE have already been used for the assessment of Achilles tendons, patellar tendon, quadriceps tendon, epicondylar tendons and rotator cuff tendons and muscles. Achilles tendinopathy is the most studied tendon injury with USE, including the postoperative period after surgical repair of Achilles rupture tendon. In relation to conventional ultrasound (US), USE potentially increases the sensitivity and diagnostic accuracy in tendinopathy, and can detect pathological changes before they are visible in conventional US imaging. Several technical limitations are recognised, and standardisation is necessary to ensure repeatability and comparability of the results when using these techniques. Still, USE is a promising technique under development and may be used not only to promote an early diagnosis, but also to identify the risk of injury and to support the evaluation of rehabilitation interventions. Key Points • USE is used for the assessment of the mechanical properties of tissues, including the tendons. • USE increases diagnostic performance when coupled to conventional US imaging modalities. • USE will be useful in early diagnosis, tracking outcomes and monitoring treatments of tendon injury. • Technical issues and lack of standardisation limits USE use in the assessment of tendon injury.
