Authors: Schiff Melissa A. , Mack Christopher D. , Polissar Nayak L. , Levy Marni R. , Dow Sara P. , O'Kane John W. 
Published: May 2010

Abstract

Context:
Few authors have evaluated sports injury-surveillance systems that use parental, Internet-based surveys for data collection.

Objective:
To determine whether certified athletic trainers (ATs) and parental, Internet-based surveys provided comparable data for identifying soccer injuries.

Design:
Prospective feasibility cohort study.

Setting:
A soccer association in Seattle, Washington.

Patients or Other Participants:
Eighty female youth soccer players, ages 12 to 14 years.

Main Outcome Measure(s):
We compared the data provided by ATs attending 1 soccer practice per week with a weekly soccer-parent, Internet-based system. We measured athlete-exposure hours (AEHs) for each player. We compared injury rates reported by ATs only, Internet-based surveys only, and both systems combined. We evaluated the 2 surveillance systems for agreement on injured body region and laterality of injury using the κ statistic.

Results:
For ATs only, Internet-based surveys only, and both systems combined, we found acute injury rates of 3.0 per 1000 AEHs, 3.9 per 1000 AEHs, and 4.7 per 1000 AEHs and overuse injury rates of 1.0 per 1000 AEHs, 2.9 per 1000 AEHs, and 2.9 per 1000 AEHs, respectively. Players sustained 27 acute injuries (44% ankle, 11% knee, 11% hip) reported by at least 1 of the 2 systems, with 63% reported by ATs and 85% by Internet-based survey. Players sustained 17 overuse injuries (35% knee, 29% lower leg) reported by either system, with 35% reported by ATs and 100% by Internet-based survey. Among players for whom we had both ATs' and Internet-based survey injury data, body region injured and laterality had very good agreement (κ  =  0.73 to 1.0).

Conclusions:
The injury rate based on the weekly parental, Internet-based survey was similar to the rate based on the ATs' reporting and had comparable classifications of injured body region and laterality of injury.
Electrocardiogram Testing During Athletic Preparticipation Physical Examinations
Authors: O'Connor Daniel P. , Knoblauch Mark A. 
Published: May 2010

Abstract

Context:
Sudden cardiac death (SCD) is a relatively rare yet unfortunate risk of athletic participation. To reduce the incidence of SCD, electrocardiogram (ECG) use during athletic preparticipation examinations (PPEs) has been proposed to detect underlying cardiac abnormalities.

Objective:
To estimate the effectiveness of ECG use during athletic PPEs.

Design:
Epidemiologic modeling.

Populations:
Public high school athletes.

Data Collection and Analysis:
Estimates of ECG sensitivity (70%) and specificity (84%) were drawn from the literature, as was the estimate of overall prevalence of cardiac conditions relevant to SCD (0.3%). Participation rate by sex was determined from National Federation of State High School Associations data. Participation by ethnicity was assumed to be proportionate to the public high school attendance rates for grades 9 through 12 (18.4% African American). Population-specific ECG effectiveness (positive predictive value), estimated total costs, cost per year of life saved, and cost to identify 1 additional case were computed. Total annual PPE screening costs reflected a cardiologist's office visit, including echocardiogram for those athletes with a positive ECG screen.

Results:
The model predicted that 16% of all athletes would be expected to have a positive ECG, but only 1.3% of athletes with a positive ECG would have a cardiac abnormality capable of causing SCD, including hypertrophic cardiomyopathy, structural defects, and various conduction abnormalities. Total annual cost estimates for ECG screening and follow-up exceeded $126 million. Average cost per year of life saved across groups was $2693, and the cost to identify 1 additional case averaged $100 827. Compared with females, males had both lower cost per year of life saved and lower cost to identify 1 true case. Similarly, black males exhibited lower costs than white males. Across groups, false-positive ECG screening exams accounted for 98.8% of follow-up costs.

Conclusions:
Large-scale, mass ECG testing would be a costly method to identify athletes with cardiac abnormalities. Targeting high-risk populations can increase the effectiveness of the ECG for athletic PPE screening.
Formal and Informal Continuing Education Activities and Athletic Training Professional Practice
Authors: Armstrong Kirk J. , Weidner Thomas G. 
Published: May 2010

AbstractContext:Continuing education (CE) is intended to promote professional growth and, ultimately, to enhance professional practice.Objective:To determine certified athletic trainers' participation in formal (ie, approved for CE credit) and informal (ie, not approved for CE credit) CE activities and the perceived effect these activities have on professional practice with regard to improving knowledge, clinical skills and abilities, attitudes toward patient care, and patient care itself.Design:Cross-sectional study.Setting:Athletic training practice settings.Patients or Other Participants:Of a geographic, stratified random sample of 1000 athletic trainers, 427 (42.7%) completed the survey.Main Outcome Measure(s):The Survey of Formal and Informal Athletic Training Continuing Education Activities was developed and administered electronically. The survey consisted of demographic characteristics and Likert-scale items regarding CE participation and perceived effect of CE on professional practice. Internal consistency of survey items was determined using the Cronbach α (α  =  0.945). Descriptive statistics were computed for all items. An analysis of variance and dependent t tests were calculated to determine differences among respondents' demographic characteristics and their participation in, and perceived effect of, CE activities. The α level was set at .05.Results:Respondents completed more informal CE activities than formal CE activities. Participation in informal CE activities included reading athletic training journals (75.4%), whereas formal CE activities included attending a Board of Certification–approved workshop, seminar, or professional conference not conducted by the National Athletic Trainers' Association or affiliates or committees (75.6%). Informal CE activities were perceived to improve clinical skills or abilities and attitudes toward patient care. Formal CE activities were perceived to enhance knowledge.Conclusions:More respondents completed informal CE activities than formal CE activities. Both formal and informal CE activities were perceived to enhance athletic training professional practice. Informal CE activities should be explored and considered for CE credit.
Cryotherapy and Joint Position Sense in Healthy Participants: A Systematic Review
Authors: Costello Joseph T. , Donnelly Alan E. 
Published: May 2010

Abstract

Objective:
To (1) search the English-language literature for original research addressing the effect of cryotherapy on joint position sense (JPS) and (2) make recommendations regarding how soon healthy athletes can safely return to participation after cryotherapy.

Data Sources:
We performed an exhaustive search for original research using the AMED, CINAHL, MEDLINE, and SportDiscus databases from 1973 to 2009 to gather information on cryotherapy and JPS. Key words used were cryotherapy and proprioception, cryotherapy and joint position sense, cryotherapy, and proprioception.

Study Selection:
The inclusion criteria were (1) the literature was written in English, (2) participants were human, (3) an outcome measure included JPS, (4) participants were healthy, and (5) participants were tested immediately after a cryotherapy application to a joint.

Data Extraction:
The means and SDs of the JPS outcome measures were extracted and used to estimate the effect size (Cohen d) and associated 95% confidence intervals for comparisons of JPS before and after a cryotherapy treatment. The numbers, ages, and sexes of participants in all 7 selected studies were also extracted.

Data Synthesis:
The JPS was assessed in 3 joints: ankle (n  =  2), knee (n  =  3), and shoulder (n  =  2). The average effect size for the 7 included studies was modest, with effect sizes ranging from −0.08 to 1.17, with a positive number representing an increase in JPS error. The average methodologic score of the included studies was 5.4/10 (range, 5–6) on the Physiotherapy Evidence Database scale.

Conclusions:
Limited and equivocal evidence is available to address the effect of cryotherapy on proprioception in the form of JPS. Until further evidence is provided, clinicians should be cautious when returning individuals to tasks requiring components of proprioceptive input immediately after a cryotherapy treatment.

ImportanceLipoprotein(a) (Lp[a]) is thought to be the major carrier of oxidized phospholipids (OxPL). OxPL are believed to be a potent driver of inflammation and atherosclerosis. Olpasiran, a small interfering RNA, blocks Lp(a) production by inducing degradation of apolipoprotein(a) messenger RNA. Olpasiran’s effects on OxPL and systemic markers of inflammation are not well described.ObjectiveTo assess the effects of olpasiran on OxPL, high-sensitivity interleukin 6 (hs-IL-6), and hs-C-reactive protein (hs-CRP) in the OCEAN(a)-DOSE randomized clinical trial.Design, Setting, and ParticipantsOCEAN(a)-DOSE was an international, multicenter, placebo-controlled, phase 2, dose-finding randomized clinical trial conducted between July 2020 and November 2022. A total of 281 patients with atherosclerotic cardiovascular disease and Lp(a) levels greater than 150 nmol/L were included.InterventionParticipants were randomized to receive 1 of 4 active subcutaneous doses of olpasiran vs placebo: (1) 10 mg, administered every 12 weeks (Q12W); (2) 75 mg, Q12W; (3) 225 mg, Q12W; or (4) 225 mg, administered every 24 weeks (Q24W). OxPL on apolipoprotein B (OxPL-apoB), hs-CRP, and hs-IL-6 were assessed at baseline, week 36, and week 48 in 272 patients.Main Outcomes and MeasuresThe primary outcome was placebo-adjusted change in OxPL-apoB from baseline to week 36.ResultsAmong 272 participants, median (IQR) age was 62 years (56-69), and 86 participants (31.6%) were female. Baseline median (IQR) Lp(a) concentration was 260.3 nmol/L (198.1-352.4) and median (IQR) OxPL-apoB concentration was 26.5 nmol/L (19.7-33.9). The placebo-adjusted mean percentage change in OxPL-apoB from baseline to week 36 was −51.6% (95% CI, −64.9% to −38.2%) for the 10-mg Q12W dose, −89.7% (95% CI, −103.0% to −76.4%) for the 75-mg Q12W dose, −92.3% (95% CI, −105.6% to −78.9%) for the 225-mg Q12W dose, and −93.7% (95% CI, −107.1% to −80.3%) for the Q24W dose (P &amp;lt; .001 for all). These effects were maintained to week 48 (−50.8%, −100.2%, −104.7%, and −85.8%, respectively; P &amp;lt; .001 for all). There was a strong correlation between percentage reduction in Lp(a) and OxPL-apoB for patients treated with olpasiran (r = 0.79; P &amp;lt; .001). Olpasiran did not significantly impact hs-CRP or hs-IL-6 compared with placebo to weeks 36 or 48 (P &amp;gt; .05).Conclusion and RelevanceIn the OCEAN(a)-DOSE multicenter randomized clinical trial, olpasiran led to a significant and sustained reduction in OxPL-apoB but no significant effects on hs-CRP or hs-IL-6.

ImportanceThe impact of Medicaid telehealth reimbursement policies on staffing and patient-centered care in the safety net are largely unknown but critical to successful and equitable access to telehealth.ObjectiveTo identify and characterize federally qualified health center (FQHC) staff and leadership’s perceptions of the benefits and drawbacks of Medicaid telehealth reimbursement policies.Design, Setting, and ParticipantsThis qualitative study used semistructured interviews conducted from April 2022 to January 2024 with snowballed sampled participants consisting of FQHC leadership, clinicians, and administrative staff in 6 FQHCs representing the 5 boroughs in New York, New York.Main Outcomes and MeasuresParticipants described telehealth experiences, including factors impending or contributing to staff turnover, patient satisfaction, and financial sustainability within FQHCs. Thematic analysis was used to analyze the data.ResultsOf 56 interviews, 26 participants (46.4%) were part of the leadership team, 18 (32.1%) were clinical staff, 8 (14.3%) were program support staff, 7 (12.5%) were enabling services staff, 3 (5.4%) were site directors, and 3 (5.4%) were another staff category. Three overarching themes characterized staff and leadership understanding of the impact of Medicaid telehealth reimbursement policies on FQHCs: (1) Medicaid telehealth policy design was perceived to exacerbate a workforce shortage, particularly among mental health care practitioners; (2) patients ranged in preferences and ability to access telehealth while FQHCs struggled to attain resources for telehealth; and (3) FQHC leadership envisioned a productive hybrid model where telehealth complements on-site care. FQHC staff and leadership reported opportunities to improve compliance, no-shows, and workflows through telehealth, but improvements in funding policy, such as payment parity and more grants that can be used to address telehealth infrastructure (eg, Internet access, equipment, and literacy), are urgently needed.Conclusions and RelevanceIn this qualitative study, staff at FQHCs perceived the current telehealth Medicaid reimbursement policies in New York State as a factor that exacerbated inequities to accessing care, particularly for mental health needs. These findings indicate that although telehealth brings new opportunities to advance patient-centered care, there are serious challenges on the path toward equitable care because telehealth is not yet integrated into payment in a sustainable way.

Published: February 2025

AbstractCombining interfacial solar steam evaporation with power generation to produce freshwater and electricity is an effective approach to alleviating freshwater scarcity and energy crises. However, constructing low‐cost, efficient integrated evaporator‐generator devices remains challenging, and the synergistic mechanism underlying evaporation‐power co‐generation is not yet well understood. Herein, low‐cost carbon foam‐based bifunctional evaporators that effectively achieve freshwater and electricity co‐generation are designed. Carbon foam is obtained from waste polyester using a ball‐milling‐assisted carbonization strategy. The bifunctional evaporator demonstrates excellent water transport, outstanding sunlight absorption, and low evaporation enthalpy. It achieves an ultra‐high evaporation rate of 3.03 kg m−2 h−1 with a conversion efficiency of 99.4%. Additionally, it exhibits continuous high voltage (0.33 V) and current output (14.4 µA), surpassing the performance of state‐of‐the‐art carbon materials‐based evaporators/generators. The outcome of molecular dynamics simulations demonstrates that the stronger interaction of surface functional groups in carbon foam with Na+ than Cl− results in the formation of flow potential, when exposed to sunlight, further insights into the synergistic mechanism of power generation. This study expands a new path for sustainable electricity and freshwater co‐production by collecting natural energy using single, low‐cost, carbon foam‐based functional evaporator devices.

Published: February 2025

AbstractBlue phase liquid crystal (BPLC) dynamic patterns have attracted wide attention for promising applications in optical information manipulation and visualization sensing, owing to unique 3D chiral helix superstructure and adjustable bright/abundant colors in response to extra fields. Inkjet printing has become an efficient approach for achieving programmable BPLC patterns. However, it remains a challenge to achieve independent “on/off” control of regional colors using the same ink due to unrevealed temperature‐time‐dependent color change behavior determined by different inks. Herein, a comprehensive understanding of the reflective bandgap shift law versus temperature/time is established by investigating the diffusion kinetics of multiple inks (5CB, 6CB, 8CB) in hydrophobically modified blue‐phase polymer templates. The three inks induce a redshift followed by a blueshift in color/reflectance wavelengths, but triggering times differ significantly at the same temperature, which is attributed to the inks' phase transition characteristics, fluid properties, and interaction with the BPLC polymer network. Dynamic multi‐color patterns with selective region triggering are successfully fabricated based on the time‐temperature controlled multi‐ink printing technique for displaying time‐series information and multi‐level encryption (including “growing apple tree” and “nested QR codes”). This study provides important insights into the design and fabrication of advanced optical devices with programmable colors and patterns.

AbstractStructural anisotropy in micro‐ and nanoscale magnetic materials is critical for their magnetic response to high‐frequency electromagnetic (EM) fields. However, controlling and visualizing these magnetic properties at the nanoscale remains a significant challenge. In this study, it proposes a strategy for the directional regulation of anisotropy in iron‐based magnetic materials. By manipulating particle structures, preferential orientation designs are achieved, resulting in spherical, spindle‐shaped, symmetrical hexagonal cone‐shaped, and disc‐shaped morphologies. Utilizing off‐axis electron holography and micromagnetic simulations, it observes that the material's response to high‐frequency EM waves intensifies with increasing structural anisotropy. This enhanced anisotropy directly influences high‐frequency magnetic permeability, enabling effective modulation of EM waves. Building on these insights, spindle‐shaped magnetic structures are developed with strong uniaxial anisotropy, achieving enhanced microwave absorption and surpassing the Snoek limit. These structures exhibit an initial permeability of up to 2.03, a 35% improvement over isotropic structures. They cover the 4.58–7.88 GHz range, providing absorption across more than 50% of the wireless communication band with a thin coating of just 3.0 mm, outperforming existing absorbers. Notably, the absorption bands predominantly lie within civilian frequency ranges (2–8 GHz), offering electromagnetic pollution protection for 5G and future 6G communication technologies.

AbstractThe catalytic conversion of bioethanol to ethylene (C2H4) and acetylene (C2H2) offers a transformative approach to sustainable production of two industrial cornerstones for organic compound and polymer syntheses, thereby offering significant economic and environmental advantages. In contrast, current methods for the synthesis of these C2 hydrocarbons rely on energy‐ and carbon‐intensive processes that require high temperatures and pressures. The present work addresses these limitations with a novel, low‐energy, bioethanol‐conversion strategy operating at room temperature and ambient pressure using sono‐piezo‐photocatalysts. A novel heterostructure of graphene oxide fragments (GO) and sodium bismuth titanate (NBT) within a core‐shell microstructure achieved outstanding C2H4 and C2H2 production rates of 134.1 and 55.5 µmol/g/h, respectively. The conversion mechanism is driven by (1) bubble collapse during ultrasound irradiation, generating localized high temperatures (≈4000 K) and pressures (≈100 MPa), and (2) piezo‐photocatalytic tuning of GO/NBT by enhanced charge separation and transfer. DFT simulations revealed detailed sono‐piezo‐photocatalytic conversion pathways, showing significant reductions in energy barriers for C2H4 (22.0 kcal mol−1) and C2H2 (48.0 kcal mol−1) formation. These findings emphasize the critical role of the catalyst in cleaving both C─H and C─O bonds effectively, leading to the desired product formation.

Published: February 2025

AbstractExtracellular vesicles (EVs) have emerged as promising bioactive carriers for delivering therapeutic agents, including nucleic acids, proteins, and small‐molecule drugs, owing to their excellent physicochemical stability and biocompatibility. However, comprehensive reviews on the various types of EV‐based nanomedicines for cancer therapy remain scarce. This review explores the potential of EVs as antitumor nanomedicines. Methods for EV extraction, drug loading, and engineering modifications are systematically examined, and the strengths and limitations of these technical approaches are critically assessed. Additionally, key strategies for developing EV‐based antitumor therapies are highlighted. Finally, the opportunities and challenges associated with advancing EVs toward clinical translation are discussed. With the integration of multiple disciplines, robust EV‐based therapeutic platforms are expected to be manufactured to provide more personalized and effective solutions for oncology patients.
