RESUMO

We present a panel dataset of COVID-19 vaccine policies, with data from 01 January 2020 for 185 countries and a number of subnational jurisdictions, reporting on vaccination prioritization plans, eligibility and availability, cost to the individual and mandatory vaccination policies. For each of these indicators, we recorded who is targeted by a policy using 52 standardized categories. These indicators document a detailed picture of the unprecedented scale of international COVID-19 vaccination rollout and strategy, indicating which countries prioritized and vaccinated which groups, when and in what order. We highlight key descriptive findings from these data to demonstrate uses for the data and to encourage researchers and policymakers in future research and vaccination planning. Numerous patterns and trends begin to emerge. For example: 'eliminator' countries (those that aimed to prevent virus entry into the country and community transmission) tended to prioritize border workers and economic sectors, while 'mitigator' countries (those that aimed to reduce the impact of community transmission) tended to prioritize the elderly and healthcare sectors for the first COVID-19 vaccinations; high-income countries published prioritization plans and began vaccinations earlier than low- and middle-income countries. Fifty-five countries were found to have implemented at least one policy of mandatory vaccination. We also demonstrate the value of combining this data with vaccination uptake rates, vaccine supply and demand data, and with further COVID-19 epidemiological data.

RESUMO

Early intervention within First Episode Psychosis (FEP) recovery efforts support functional recovery in several ways, including increasing levels of (1) physical activity (2) life skills, and (3) social connectivity. Sport has been proposed as an ideal platform to target these three goals simultaneously. The primary aims were to assess the feasibility of utilising sport-based life skills within FEP recovery efforts and test intervention components. The secondary aim was to evaluate the potential recovery benefits. Seven young people (aged 15-25 years) with FEP participated in a six-week sport programme alongside their support workers (community and peer workers) from the service, including peer workers with a lived experience of psychosis. The programme consisted of various sporting activities, which were designed to promote physical activity, maximise social connectivity, and teach life-skills (e.g. motivation, emotional regulation, and goal-setting) that are relevant and transferrable to other contexts (e.g. school, employment, independent living). The support participants engaged with the programme at the same level as the young people, with the role of providing support and normalising/modelling engagement. The young and support participants provided feedback during and after the programme via questionnaires and interviews. Young participants self-reported physical activity levels, psychological needs, recovery dimensions, and life skills pre- and post- intervention using established psychometric tools. We used thematic analysis to analyse the qualitative data and compared this information with other data collected (e.g. attendance, feedback, quantitative measurements). The study culminated with a process evaluation. The results indicated that, despite challenges with engagement for young people with FEP, sport-based life skills programming may be a feasible and useful recovery outlet. In addition, the results highlighted specific intervention components that were useful to promote engagement and recovery benefits. This study serves as a critical foundation for future sport-based work within FEP recovery.

RESUMO

During the first year of the COVID-19 pandemic, non-pharmaceutical interventions (NPIs) were the main pillar of defence to protect human society against the virus. While a variety of modelling studies try to quantify the effects of NPIs, this paper investigates when and how national and subnational governments have taken actions. We observe longitudinal changes in the global pattern of policymaking to combat the COVID-19 pandemic, with a particular focus on stay-at-home orders. Drawing on data from the Oxford COVID-19 Government Response Tracker, we show several important trends. First, while national governments exhibited a strong alignment in policy settings initially in March and April 2020, their cross-country policy heterogeneity has grown since May 2020, although countries within global regions continue to display similarities in their approaches. Second, most governments that have implemented multiple stay-at-home orders over the course of the pandemic have become less sensitive to case levels (insofar as they implement subsequent restrictions at progressively higher case levels), apart from a small number of contrast cases which have mostly eliminated domestic community transmission. Third, pandemic policies are increasingly specific to subnational levels, and there is often significant heterogeneity with regard to policy approaches even within the same country.

RESUMO

COVID-19 has prompted unprecedented government action around the world. We introduce the Oxford COVID-19 Government Response Tracker (OxCGRT), a dataset that addresses the need for continuously updated, readily usable and comparable information on policy measures. From 1 January 2020, the data capture government policies related to closure and containment, health and economic policy for more than 180 countries, plus several countries' subnational jurisdictions. Policy responses are recorded on ordinal or continuous scales for 19 policy areas, capturing variation in degree of response. We present two motivating applications of the data, highlighting patterns in the timing of policy adoption and subsequent policy easing and reimposition, and illustrating how the data can be combined with behavioural and epidemiological indicators. This database enables researchers and policymakers to explore the empirical effects of policy responses on the spread of COVID-19 cases and deaths, as well as on economic and social welfare.

RESUMO

We provide an assessment of the impact of government closure and containment measures on deaths from COVID-19 across sequential waves of the COVID-19 pandemic globally. Daily data was collected on a range of containment and closure policies for 186 countries from January 1, 2020 until March 11th, 2021. These data were combined into an aggregate stringency index (SI) score for each country on each day (range: 0-100). Countries were divided into successive waves via a mathematical algorithm to identify peaks and troughs of disease. Within our period of analysis, 63 countries experienced at least one wave, 40 countries experienced two waves, and 10 countries saw three waves, as defined by our approach. Within each wave, regression was used to assess the relationship between the strength of government stringency and subsequent deaths related to COVID-19 with a number of controls for time and country-specific demographic, health system, and economic characteristics. Across the full period of our analysis and 113 countries, an increase of 10 points on the SI was linked to 6 percentage points (P < 0.001, 95% CI = [5%, 7%]) lower average daily deaths. In the first wave, in countries that ultimately experiences 3 waves of the pandemic to date, ten additional points on the SI resulted in lower average daily deaths by 21 percentage points (P < .001, 95% CI = [8%, 16%]). This effect was sustained in the third wave with reductions in deaths of 28 percentage points (P < .001, 95% CI = [13%, 21%]). Moreover, interaction effects show that government policies were effective in reducing deaths in all waves in all groups of countries. These findings highlight the enduring importance of non-pharmaceutical responses to COVID-19 over time.

RESUMO

Glucose serves as the major energy substrate for articular chondrocytes and as the main precursor for the synthesis of extracellular matrix glycosaminoglycans in cartilage. Chondrocytes have been shown to express several glucose transporter (GLUT) isoforms including GLUT1 and GLUT3. The aim of this investigation was to determine the effects of endocrine and cytokine factors on the capacity of equine articular chondrocytes for transporting 2-deoxy-d-[2,6-3H] glucose and on the expression levels of GLUT1 and GLUT3. Chondrocytes maintained in monolayer culture were stimulated for 24 h with TNF-alpha (100 ng mL(-1)), IL-1beta (100 ng mL(-1)), IGF-I (20 ng mL(-1)), TGF-beta (20 ng mL(-1)) and insulin (12.5 microg mL(-1)) before measuring uptake of non-metabolizable 2-deoxyglucose in the presence and absence of the glucose transport inhibitor cytochalasin B. Polyclonal antibodies to GLUT1 and GLUT were used to compare GLUT1 and GLUT3 expression in stimulated and un-stimulated alginate encapsulated chondrocytes by Western blotting. Results indicated that 2-deoxyglucose uptake was inhibited by up to 95% in the presence of cytochalasin B suggesting that glucose uptake into equine chondrocytes is GLUT-mediated. Insulin had no effect on glucose uptake, but treatment with IGF-I, TGF-beta, IL-1beta and TNF-alpha resulted in a significant increase (>65%) in 2-deoxyglucose uptake compared to control values. GLUT1 was found to be increased in chondrocytes stimulated with all the growth factors and cytokines but GLUT 3 was only upregulated by IGF-I. The data presented support a critical role for glucose in the responses of equine articular chondrocytes to pro-inflammatory cytokines and anabolic endocrine factors.
