Circus-specific extension of the International Olympic Committee consensus statement: Methods for recording and reporting of epidemiological data on injury and illness in sport 2020

Indepth knowledge of injury and illness epidemiology in circus arts is lacking. Comparing results across studies is difficult due to inconsistent methods and definitions. In 2020, the International Olympic Committee (IOC) consensus group proposed a standard method for recording and reporting epidemiological data on injuries and illnesses in sports and stated that sport-specific extension statements are needed to capture the context of each sport. This is the circus-specific extension to be used with the IOC consensus statement. International circus arts researchers in injury and illness epidemiology and performing arts medicine formed a consensus working group. Consensus statement development included a review of literature, creation of an initial draft by the working group, feedback from external reviewers, integration of feedback into the second draft and a consensus on the final document. This consensus statement contains circus-specific information on (1) injury definitions and characteristics; (2) measures of severity and exposure, with recommendations for calculating the incidence and prevalence; (3) a healthcare practitioner report form; (4) a self-report form capturing health complaints with training and performance exposure; and (5) a demographic, health history and circus experience intake questionnaire. This guideline facilitates comparing results across studies and enables combining data sets on injuries in circus arts. This guideline informs circus-specific injury prevention, rehabilitation, and risk management to improve the performance and health of circus artists

The ‘Keynesian Moment’ in Policymaking, the Perils Ahead, and a Flow-of-Funds Interpretation of Fiscal Policy

With the global crisis, the policy stance around the world has been shaken by massive government and central bank efforts to prevent the meltdown of markets, banks, and the economy. Fiscal packages, in varied sizes, have been adopted throughout the world after years of proclaimed fiscal containment. This change in policy regime, though dubbed the 'Keynesian moment,' is a 'short-run fix' that reflects temporary acceptance of fiscal deficits at a time of political emergency, and contrasts with John Maynard Keynes's long-run policy propositions. More important, it is doomed to be ineffective if the degree of tolerance of fiscal deficits is too low for full employment. Keynes's view that outside the gold standard fiscal policies face real, not financial, constraints is illustrated by means of a simple flow-of-funds model. This shows that government deficits do not take financial resources from the private sector, and that demand for net financial savings by the private sector can be met by a rising trade surplus at the cost of reduced consumption, or by a rising government deficit financed by the monopoly supply of central bank credit. Fiscal deficits can thus be considered functional to the objective of supplying the private sector with a provision of financial wealth sufficient to restore demand. By contrast, tax hikes and/or spending cuts aimed at reducing the public deficit lower the available savings of the private sector, and, if adopted too soon, will force the adjustment by way of a reduction of demand and standard of living. This notion, however, is not applicable to the euro area, where constraints have been deliberately created that limit public deficits and the supply of central bank credit, thus introducing national solvency risks. This is a crucial flaw in the institutional structure of Euroland, where monetary sovereignty has been removed from all existing fiscal authorities. Absent a reassessment of its design, the euro area is facing a deflationary tendency that may further erode the economic welfare of the region

Estrogenic botanical supplements, health-related quality of life, fatigue, and hormone-related symptoms in breast cancer survivors: a HEAL study report

<p>Abstract</p> <p>Background</p> <p>It remains unclear whether estrogenic botanical supplement (EBS) use influences breast cancer survivors' health-related outcomes.</p> <p>Methods</p> <p>We examined the associations of EBS use with health-related quality of life (HRQOL), with fatigue, and with 15 hormone-related symptoms such as hot flashes and night sweats among 767 breast cancer survivors participating in the Health, Eating, Activity, and Lifestyle (HEAL) Study. HRQOL was measured by the Medical Outcomes Study short form-36 physical and mental component scale summary score. Fatigue was measured by the Revised-Piper Fatigue Scale score.</p> <p>Results</p> <p>Neither overall EBS use nor the number of EBS types used was associated with HRQOL, fatigue, or hormone-related symptoms. However, comparisons of those using each specific type of EBS with non-EBS users revealed the following associations. Soy supplements users were more likely to have a better physical health summary score (odds ratio [OR] = 1.66, 95% confidence interval [CI] = 1.02-2.70). Flaxseed oil users were more likely to have a better mental health summary score (OR = 1.76, 95% CI = 1.05-2.94). Ginseng users were more likely to report severe fatigue and several hormone-related symptoms (all ORs ≥ 1.7 and all 95% CIs exclude 1). Red clover users were less likely to report weight gain, night sweats, and difficulty concentrating (all OR approximately 0.4 and all 95% CIs exclude 1). Alfalfa users were less likely to experience sleep interruption (OR = 0.28, 95% CI = 0.12-0.68). Dehydroepiandrosterone users were less likely to have hot flashes (OR = 0.33, 95% CI = 0.14-0.82).</p> <p>Conclusions</p> <p>Our findings indicate that several specific types of EBS might have important influences on a woman's various aspects of quality of life, but further verification is necessary.</p

The Freedom Budget at 45: Functional Finance and Full Employment

Forty-five years ago, the A. Philip Randolph Institute issued The Freedom Budget, in which a program for economic transformation was proposed that included a job guarantee for everyone ready and willing to work, a guaranteed income for those unable to work or those who should not be working, and a living wage to lift the working poor out of poverty. Such policies were supported by a host of scholars, civic leaders, and institutions, including the Rev. Dr. Martin Luther King Jr.; indeed, they provided the cornerstones for King's Poor Peoples' Campaign and economic bill of rights. This paper proposes a New Freedom Budget for full employment based on the principles of functional finance. To counter a major obstacle to such a policy program, the paper includes a primer on three paradigms for understanding government budget deficits and the national debt: the deficit hawk, deficit dove, and functional finance perspectives. Finally, some of the benefits of the job guarantee are outlined, including the ways in which the program may serve as a vehicle for a variety of social policies

A Retrospective Look at the U.S. Productivity Growth Resurgence

It is now widely recognized that information technology (IT) was critical to the dramatic acceleration of U.S. labor productivity growth in the mid-1990s. This paper traces the evolution of productivity estimates to document how and when this perception emerged. Early studies concluded that IT was relatively unimportant. It was only after the massive IT investment boom of the late 1990s that this investment and underlying productivity increases in the IT-producing sectors were identified as important sources of growth. Although IT has diminished in significance since the dot-com crash of 2000, we project that private sector productivity growth will average around 2.5 percent per year for the next decade, a pace that is only moderately below the average for the 1995-2005 period

A checklist for assessing the methodological quality of concurrent tES-fMRI studies (ContES checklist): a consensus study and statement

Background: Low intensity transcranial electrical stimulation (tES), including alternating or direct current stimulation (tACS or tDCS), applies weak electrical stimulation to modulate the activity of brain circuits. Integration of tES with concurrent functional magnetic resonance imaging (fMRI) allows for the mapping of neural activity during neuromodulation, supporting causal studies of both brain function and tES effects. Methodological aspects of tES-fMRI studies underpin the results, and reporting them in appropriate detail is required for reproducibility and interpretability. Despite the growing number of published reports, there are no consensus-based checklists for disclosing methodological details of concurrent tES-fMRI studies. Objective: To develop a consensus-based checklist of reporting standards for concurrent tES-fMRI studies to support methodological rigor, transparency, and reproducibility (ContES Checklist). Methods: A two-phase Delphi consensus process was conducted by a steering committee (SC) of 13 members and 49 expert panelists (EP) through the International Network of the tES-fMRI (INTF) Consortium. The process began with a circulation of a preliminary checklist of essential items and additional recommendations, developed by the SC based on a systematic review of 57 concurrent tES-fMRI studies. Contributors were then invited to suggest revisions or additions to the initial checklist. After the revision phase, contributors rated the importance of the 17 essential items and 42 additional recommendations in the final checklist. The state of methodological transparency within the 57 reviewed concurrent tES-fMRI studies was then assessed using the checklist. Results: Experts refined the checklist through the revision and rating phases, leading to a checklist with three categories of essential items and additional recommendations: (1) technological factors, (2) safety and noise tests, and (3) methodological factors. The level of reporting of checklist items varied among the 57 concurrent tES-fMRI papers, ranging from 24% to 76%. On average, 53% of checklist items were reported in a given article. Conclusions: Use of the ContES checklist is expected to enhance the methodological reporting quality of future concurrent tES-fMRI studies, and increase methodological transparency and reproducibility

Untangling risk factors including discipline-specific exposure for injuries in preprofessional and professional circus artists in the USA

Objective This prospective cohort study quantified injury patterns related to specific circus discipline exposure in preprofessional and professional circus artists.Methods Circus artists (n=201; ages 13–69; 172 female, 29 male assigned sex at birth) were enrolled in 10 cities across the USA. Participants were followed for 1 year from enrolment, completing a weekly training log and undergoing a physical therapist evaluation for injuries. The circus-specific extension of the International Olympic Committee 2020 consensus on recording injury and illness in sports was used to analyse injury patterns.Results The study completion rate was 77% (n=155). Data were analysed by participant subgroup (age, professional status, sex at birth). The highest injury rates in participant subgroups were for males (5.69/1000 exposures) and related to discipline subgroups, were in aerial with ground elements (5.93/1000 exposures) and aerial (4.26/1000 exposures). Adults had more injuries related to aerial, whereas adolescents had more related to ground disciplines (χ2 (2)=10.62, p=0.005) and non-time loss injuries (χ2 (1)=5.45, p=0.02). Females had a higher proportion of repetitive injuries (70% vs 55%) than males (χ2 (1) = 4.43, p=0.035). Individuals with an eating disorder history had more (p&lt;0.004) injuries (mean 2.27±2.29) than those without (mean=1.48±0.96).Conclusions This study showed that intrinsic factors (age, sex at birth and history of eating disorder) and extrinsic factors (circus discipline exposure) affect injury risk. We need to account for the intersectionality of these factors to address risk management at an individual and group level
