Campus Recreation and Fitness Center Utilization During the COVID-19 Pandemic

Background The impact of the COVID-19 pandemic has far reaching effects for college students\u27 health and physical activity behaviors. This analysis focuses on university student fitness center usage pre and during the COVID-19 pandemic. Researchers hypothesized a reduction in fitness center utilization when comparing Fall 2019 to Fall 2020 utilization rates. Methods Patterns of the recreation center and fitness center utilization during the COVID-19 pandemic are compared to pre-pandemic patterns of a matched time period in the previous academic year in an observational study. Overall utilization was evaluated using secondary data from the university’s recreation center data system. Six weeks of utilization data were pulled for investigation across the two years of interest. Time periods evaluated included Fall semester 2019 (August 19, 2019 - September 29, 2019) and Fall semester 2020 (August 17, 2020 - September 27, 2020). Poisson regression analysis was used where statistical significance levels were set to 0.05. Results There was a statistically significant reduction in recreation center participation from 2019 to 2020 (Mean±SD: 1683.1 ± 888.6 to 726.4 ±339.9). Furthermore, student participation decreased in all areas of the fitness center usage from 2019 to 2020 (cardio deck, machine weights, and free weights Mean±SD: 12.5±8.9 to 5.4±4.2, 17.6±9.5 to 8.9±5.4, 27.7±13.1 to 17.9±8.4). While the overall participation decreased, the proportion of utilization increased in the free weights area (B = 0.2446; 95% CI 0.1604 – 0.3289; p Conclusions This study is one of the first to evaluate the effect the COVID-19 pandemic has on participation in a university recreation center. This study will help generate questions and guide future research analyzing trends of physical activity during the COVID-19 pandemic

They are described in terms of worsening inflammation but pain and inflammation are often discordant. To inform treatment decisions, we investigated whether inflammatory and pain flares are discrete entities. Methods: People from the Early RA Network (ERAN) cohort were assessed annually up to 11 years after presentation (n = 719, 3703 person-years of follow up). Flare events were defined in 2 different ways that were analysed in parallel; DAS28 or Pain Flares. DAS28 Flares satisfied OMERACT flare criteria of increases in DAS28 since the previous assessment (≥1.2 points if active RA or ≥ 0.6 points if inactive RA). A ≥ 4.8-point worsening of SF36-Bodily Pain score defined Pain Flares. The first documented episode of each of DAS28 and Pain Flare in each person was analysed. Subgroups within DAS28 and Pain Flares were determined using Latent Class Analysis. Clinical course was compared between flare subgroups. Results: DAS28 (45%) and Pain Flares (52%) were each common but usually discordant, with 60% of participants in DAS28 Flare not concurrently in Pain Flare, and 64% of those in Pain Flare not concurrently in DAS28 Flare. Three discrete DAS28 Flare subgroups were identified. One was characterised by increases in tender/swollen joint counts (14.4%), a second by increases in symptoms (13.1%), and a third displayed lower flare severity (72.5%). Two discrete Pain Flare subgroups were identified. One occurred following low disease activity and symptoms (88.6%), and the other occurred on the background of ongoing active disease and pain (11.4%). Despite the observed differences between DAS28 and Pain Flares, each was associated with increased disability which persisted beyond the flare episode. Conclusion: Flares are both common and heterogeneous in people with RA. Furthermore our findings indicate that for some patients there is a discordance between inflammation and pain in flare events. This discrete flare subgroups might reflect different underlying inflammation and pain mechanisms. Treatments addressing different mechanisms might be required to reduce persistent disability after DAS28 and Pain Flares.Peer reviewedFinal Published versio

Discrete trajectories of resolving and persistent pain in people with rheumatoid arthritis despite undergoing treatment for inflammation: results from three UK cohorts

Rheumatoid arthritis (RA) is an example of human chronic inflammatory pain. Modern treatments suppress inflammation, yet pain remains a major problem for many people with RA. We hypothesised that discrete RA subgroups might display favourable or unfavourable pain trajectories when receiving treatment, and that baseline characteristics will predict trajectory allocation.Growth Mixture Modelling was used to identify discrete trajectories of SF36-Bodily Pain scores during 3 years in 3 RA cohorts (Early RA Network (ERAN); n=683, British Society for Rheumatology Biologics Register Biologics (n=7090) and Non-Biologics (n=1720) cohorts. Logistic regression compared baseline predictor variables between trajectories. The role of inflammation was examined in a subgroup analysis of people with normal levels of inflammatory markers after 3 years.Mean SF36-Bodily Pain scores in each cohort improved but remained throughout 3y follow up >1 SD worse than the UK general population average. Discrete Persistent Pain (59% to 79% of cohort participants) and Resolving Pain (19% to 27%) trajectories were identified in each cohort. In ERAN, a third trajectory displaying persistently Low Pain (23%) was also identified. In people with normal levels of inflammatory markers after 3 years, 65% of them were found to follow a Persistent Pain trajectory. When trajectories were compared, greater disability (aORs 2.3-2.5 per unit baseline Health Assessment Questionnaire score) and smoking history (aORs 1.6-1.8) were risk factors for Persistent Pain trajectories in each cohort.In conclusion, distinct trajectories indicate patient subgroups with very different pain prognosis during RA treatment. Inflammation does not fully explain the pain trajectories, and non-inflammatory factors as well as acute phase response predict which trajectory an individual will follow. Targeted treatments additional to those which suppress inflammation might reduce the long term burden of arthritis pain

Strong increase in ultrasound attenuation below T2 in Sr2RuO4 : possible evidence for domains

A two-component OP has multiple degrees of freedom in the superconducting state that can result in low-energy collective modes or the formation of domain walls—a possibility that would explain a number of experimental observations including the smallness of the signature of time reversal symmetry breaking at Tc and telegraph noise in critical current experiments. We use resonant ultrasound spectroscopy to perform ultrasound attenuation measurements across the superconducting Tc of Sr2RuO4. We find that compressional sound attenuation increases by a factor of 7 immediately below Tc , in sharp contrast with what is found in both conventional (s-wave) and high-Tc (d-wave) superconductors. Our observations are most consistent with the presence of domain walls that separate different configurations of the superconducting OP. The fact that we only observe an increase in sound attenuation for compressional strains, and not for shear strains, suggests an inhomogeneous superconducting state formed of two distinct, accidentally degenerate superconducting OPs that are not related to each other by symmetry. Whatever the mechanism, a factor of 7 increase in sound attenuation is a singular characteristic that must be reconciled with any potential theory of superconductivity in Sr2RuO4.Publisher PDFPeer reviewe

Irritant contact dermatitis in healthcare workers as a result of the COVID-19 pandemic: a cross-sectional study

COVID-19 healthcare workers (HCWs) require frequent handwashing and use of personal protective equipment (PPE) to prevent infection. However, evidence is emerging that these practices are causing adverse effects on their skin integrity. A single-centre, cross-sectional study of HCWs from an Irish hospital was undertaken to evaluate the degree of COVID-19-related irritant contact dermatitis (ICD) between April and May 2020. Of 270 participants surveyed, 223 (82.6%) reported symptoms of ICD. The hands were the most commonly affected site (76.47%) and the most frequently reported symptom was dry skin (75.37%). Nearly all (268; 99.26%) HCWs had increased hand-washing frequency, but 122 (45.35%) did not use emollients. In the ICD group, 24.7% cited a history of dermatitis compared with 4.3% of unaffected staff (P < 0.001). The ICD group recorded PPE usage for an average of 3.15 h compared with the non-ICD group at 1.97 h (P = 0.21). Promoting awareness of COVID-19-related ICD is vital to highlight prevention and treatment for frontline staff. Healthcare workers (HCWs) at the front line of the COVID-19 outbreak response are exposed to hazards that put them at risk of infection. Frequent hand hygiene and appropriate personal protective equipment (PPE) are recommended to prevent transmission of the virus. However, there is evidence to suggest that these practices are having a negative impact on skin health. HCWs in particular represent a high-risk group for developing occupational dermatitis, which can have a multitude of negative effects, including decreased compliance with proper PPE and adequate handwashing. We sought to evaluate the degree to which frontline staff members from a large tertiary hospital have been affected with irritant contact dermatitis (ICD) as a result of the COVID-19 pandemic

Phyllosticta citricarpa and sister species of global importance to Citrus.

Several Phyllosticta species are known as pathogens of Citrus spp., and are responsible for various disease symptoms including leaf and fruit spots. One of the most important species is P. citricarpa, which causes a foliar and fruit disease called citrus black spot. The Phyllosticta species occurring on citrus can most effectively be distinguished from P. citricarpa by means of multilocus DNA sequence data. Recent studies also demonstrated P. citricarpa to be heterothallic, and reported successful mating in the laboratory. Since the domestication of citrus, different clones of P. citricarpa have escaped Asia to other continents via trade routes, with obvious disease management consequences. This pathogen profile represents a comprehensive literature review of this pathogen and allied taxa associated with citrus, focusing on identification, distribution, genomics, epidemiology and disease management. This review also considers the knowledge emerging from seven genomes of Phyllosticta spp., demonstrating unknown aspects of these species, including their mating behaviour.TaxonomyPhyllosticta citricarpa (McAlpine) Aa, 1973.

Eplerenone attenuates pathological pulmonary vascular rather than right ventricular remodeling in pulmonary arterial hypertension

BACKGROUND: Aldosterone is a mineralocorticoid hormone critically involved in arterial blood pressure regulation. Although pharmacological aldosterone antagonism reduces mortality and morbidity among patients with severe left-sided heart failure, the contribution of aldosterone to the pathobiology of pulmonary arterial hypertension (PAH) and right ventricular (RV) heart failure is not fully understood. METHODS: The effects of Eplerenone (0.1% Inspra® mixed in chow) on pulmonary vascular and RV remodeling were evaluated in mice with pulmonary hypertension (PH) caused by Sugen5416 injection with concomitant chronic hypoxia (SuHx) and in a second animal model with established RV dysfunction independent from lung remodeling through surgical pulmonary artery banding. RESULTS: Preventive Eplerenone administration attenuated the development of PH and pathological remodeling of pulmonary arterioles. Therapeutic aldosterone antagonism - starting when RV dysfunction was established - normalized mineralocorticoid receptor gene expression in the right ventricle without direct effects on either RV structure (Cardiomyocyte hypertrophy, Fibrosis) or function (assessed by non-invasive echocardiography along with intra-cardiac pressure volume measurements), but significantly lowered systemic blood pressure. CONCLUSIONS: Our data indicate that aldosterone antagonism with Eplerenone attenuates pulmonary vascular rather than RV remodeling in PAH

Reductions in radiographic progression in early RA over 25-years: changing contribution from RF in 2 multi-centre UK inception cohorts

Objectives: To assess 5-year progression of erosions and Joint Space Narrowing (JSN), and their associations with RF status in two large, multi-centre early-RA cohorts spanning 25-years. Methods: Radiographic joint damage was recorded using the Sharp/van der Heijde (SvdH) method in the Early RA Study (ERAS) 1986-2001, and the Early RA Network (ERAN) 2002-2013. Mixed-effects negative-binomial regression estimated changes in radiographic damage over 5-years, including erosions and JSN separately. Rheumatoid Factor (RF), along with age, sex and baseline markers of disease activity were controlled for. Results: 1,216 patients from ERAS and 446 from ERAN had radiographic data. Compared to ERAS, ERAN patients had a lower mean total SvdH score at baseline (ERAN=6.2 vs. ERAS=10.5, p<0.001), and mean annual rate of change (ERAN=2.5 vs. ERAS=6.9 per year, p<0.001). 74% of ERAS and 27% of ERAN patients progressed ≥5 units. Lower scores at baseline in ERAN were largely driven by reductions in JSN (ERAS=3.9 vs. ERAN=1.2, p<0.001), along with erosions (ERAS=1.9 vs. ERAN=0.8, p<0.001). RF was associated with greater progression in each cohort, but the absolute difference in mean annual rate of change for RF positive patients was substantially higher for ERAS (RF+= 8.6 vs. RF-= 5.1, p<0.001), relative to ERAN (RF+= 2.0 vs. RF-= 1.9, p=0.855). Conclusion: Radiographic progression has significantly reduced between the two cohorts, associated with lower baseline damage and other factors, including changes in early DMARD use. The impact of RF status as a prognostic marker of clinically meaningful change in radiographic progression has markedly diminished in the context of more modern treatment.

Fair trade learning: ethical standards for community-engaged international volunteer tourism

The purpose of this paper is to articulate a set of ethical standards for international volunteer tourism. The standards are focused on promoting fair trade learning principles in the management and operation of volunteer programmes. Because of the unique social mission, research, and evaluation capacities of higher education, we propose first applying these principles specifically to international volunteer programmes operating at the university-community nexus. These standards have emerged through a collaborative, in-person and online process during the last two years with input by numerous concerned global citizens, international education practitioners and researchers, nongovernmental organization representatives, and community members. The document shared below represents current ‘best practice’ for maximizing the benefits and minimizing the negative impacts of volunteer tourism programmes for both host communities and volunteers

An investigation into CLIL-related sections of EFL coursebooks : issues of CLIL inclusion in the publishing market

The current ELT global coursebook market has embraced CLIL as a weak form of bilingual education and an innovative component to include in General English coursebooks for EFL contexts. In this paper I investigate how CLIL is included in ELT coursebooks aimed at teenaged learners, available to teachers in Argentina. My study is based on the content analysis of four series which include a section advertised as CLIL-oriented. Results suggest that such sections are characterised by (1) little correlation between featured subject specific content and school curricula in L1, (2) oversimplification of contents, and (3) dominance of reading skills development and lower-order thinking tasks. Through this study, I argue that CLIL components become superficial supplements rather than a meaningful attempt to promote weak forms of bilingual education
