Primary Care Providers' Experiences Recommending and Performing Cervical Cancer Screening for Women with Intellectual Disabilities: A Qualitative Study.

Women with intellectual and developmental disabilities (I/DD) are less likely to receive cervical cancer screening (CCS) relative to women without disabilities. Primary care providers (PCPs) play key roles in recommending CCS. The purpose of this study was to identify factors PCPs consider when recommending and performing CCS for women with I/DD. Using a qualitative approach, in-depth semi-structured interviews (N = 13) were conducted with majority family medicine-trained PCPs. Through inductive data analysis, it was found that most PCPs reported recommending CCS; however, follow-through for performing CCS varied. PCPs attempted to align their CCS recommendations with national guidelines and provided counseling and education to families and patients about CCS while taking an individualized risk-benefit approach. Despite most PCPs reporting a lack of knowledge or training related to providing I/DD-specific care, PCPs attempted to draw upon experiences with similar populations to recommend and perform CCS. There is an opportunity to improve knowledge of PCPs related to performing CCS for women with I/DD.

More Than Skin Deep: Patient-Provider Racial and Ethnic Concordance and Discordance in Collegiate Athletics and Concussion Management.

CONTEXT: There is strong evidence that racial and ethnic disparities exist in multiple arenas of health and wellness. The causes of racial and ethnic differences in healthcare are multi- dimensional, one factor that may impact injury/illness communication, interactions, and outcomes is patient-provider racial and ethnic concordance. At present, it is unclear what role patient-provider racial and ethnic concordance and discordance plays in facilitating concussion care for collegiate athletes. OBJECTIVE: Investigate the presence of athlete-athletic trainer (AT) racial and ethnic concordance and discordance amongst diagnosed concussion cases, and examine if racial and ethnic concordance and discordance influences time (in days) until diagnosis, symptom resolution, or return-to-sport clinical milestones in collegiate athletes. DESIGN: Retrospective cohort study. SETTING: Collegiate athletics. PATIENTS OR OTHER PARTICIPANTS: A total of 694 concussion cases [38.6% (n=268) sustained by women, 61.4% (n=426) sustained by men] that occurred within the 2015-2016 through 2019- 2020 sport seasons at 9 institutions. MAIN OUTCOME MEASURE(S): The number of days from date of injury to diagnosis, symptom resolution, and return-to-sport; and from date of diagnosis to symptom resolution and return-to- sport. RESULTS: Overall, 68.4% (n=475) of concussion cases had patient-provider racial and ethnic concordance and 31.6% (n =219) were discordant. All concordant pairs included a White athlete and White AT. Time to diagnosis differed between the concordant and discordant groups (median[IQR]=1[0,2] versus 0[0,1], respectively) only in the model adjusted for sex, sport-type, and availability of an AT (OR[CI95]=1.46[1.07, 1.85]). There were no other group differences. CONCLUSIONS: One-third of concussion cases had athlete-AT racial and ethnic discordance. While this group was diagnosed with a concussion 1-day sooner than the concordant group, no differences were observed for any concussion recovery milestones. These findings suggest that patient-provider racial and ethnic concordance may play a minor role in concussion recognition or reporting, but not necessarily in the management and recovery thereafter.

Physical activity and recovery following concussion in collegiate athletes: a LIMBIC MATARS Consortium Investigation.

OBJECTIVE: To investigate whether routine daily activities (RDA), non-prescribed exercise (Non-ERx), or prescribed exercise (ERx) were associated with recovery from sport-related concussion (SRC) in collegiate athletes. MATERIALS AND METHODS: Data for this cross-sectional, retrospective chart review of collegiate athletes diagnosed with SRC (n = 285[39.6% female], age = 19.5 ± 1.4 years) were collected during the 2015-16 to 2019-20 athletic seasons. The independent variable was group (RDA, Non-ERx, ERx). Dependent variables included days from date of diagnosis to symptom resolution (Dx-SR) and SR to return to sport (SR-RTS). RESULTS: Those in the Non-ERx group took nearly 1.3 times longer to achieve SR (IRR = 1.28, 95% CI: 1.11, 1.46) and, 1.8 times longer for RTS (IRR = 1.82, 95% CI: 1.11, 2.71) when compared to those in the RDA group. No other comparisons were significant. CONCLUSION: Collegiate athletes in the Non-ERx group took approximately 1 week longer to achieve SR as compared to the RDA and ERx groups. Our findings suggest that if exercise is recommended following SRC, it must be clearly and specifically prescribed. If exercise parameters cannot be prescribed, or monitored, RDA appear to be similarly beneficial during recovery for collegiate athletes with concussion.

Social Norms and Concussion Disclosure Behavior: Clarification of Terms and Measurement Recommendations.

Non-disclosed sport-related concussion symptoms pose a significant risk to athletes' health and well-being. Many research investigations have focused on understanding the factors impacting athletes' concussion disclosure behaviors. One of the most robust predictors of the likelihood that an athlete will disclose concussion symptoms to their coaches, athletic trainers, parents, or peers is what researchers term "social norms." The extant literature regarding social norms influencing concussion disclosure behaviors is inconsistent on how the construct should be defined, conceptualized, or measured, often failing to distinguish between descriptive and injunctive social norms and their sources (direct and indirect). In this Technical Report, we provide an overview of these critical distinctions, their importance in assessments, and examples from the literature where scholars have correctly operationalized these constructs in athletic populations. We conclude with a brief set of suggestions for researchers seeking to measure social norms in future research.

Association Between Hospital Participation in Value-Based Programs and Timely Initiation of Post-Acute Home Health Care, Functional Recovery, and Hospital Readmission After Joint Replacement.

OBJECTIVES: This study examined the association between hospital participation in Bundled Payments for Care Improvement (BPCI) or Comprehensive Care for Joint Replacement (CJR) and the timely initiation of home health rehabilitation services for lower extremity joint replacements. Furthermore, this study examined the association between the timely initiation of home health rehabilitation services with improvement in self-care, mobility, and 90-day hospital readmission. METHOD: This retrospective cohort study used Medicare inpatient claims and home health assessment data from 2016 to 2017 for older adults discharged to home with home health following hospitalization after joint replacement. Multilevel multivariate logistic regression was used to examine the association between hospital participation in BPCI or CJR programs and timely initiation of home health rehabilitation service. A 2-staged generalized boosted model was used to examine the association between delay in home health initiation and improvement in self-care, mobility, and 90-day risk-adjusted hospital readmission. RESULTS: Compared with patients discharged from hospitals that did not have BPCI or CJR, patients discharged from hospitals with these programs had a lower likelihood of delayed initiation of home health rehabilitation services for both knees and hip replacement. Using propensity scores as the inverse probability of treatment weights, delay in the initiation of home health rehabilitation services was associated with lower improvement in self-care (odds ratio [OR] = 1.23; 95% CI = 1.20-1.26), mobility (OR = 1.15; 95% CI = 1.13-1.18), and higher rate of 90-day hospital readmission (OR = 1.19; 95% CI = 1.15-1.24) for knee replacement. Likewise, delayed initiation of home health rehabilitation services was associated with lower improvement in self-care (OR = 1.16; 95% CI = 1.13-1.20) and mobility (OR = 1.26; 95% CI = 1.22-1.30) for hip replacement. CONCLUSION: Hospital participation in BPCI or comprehensive CJR was associated with early home health rehabilitation care initiation, which was further associated with significant increases in functional recovery and lower risks of hospital readmission. IMPACT: Policy makers may consider incentivizing health care providers to initiate early home health services and care coordination in value-based payment models.

Cross-sectional study of the association of social relationship resources with Staphylococcus aureus colonization in naturally occurring social groups along the US/Mexico border.

Asymptomatic carriage of Staphylococcus aureus is a major risk factor for subsequent clinical infection. Diminishing returns from mitigation efforts emphasize the need to better understand colonization, spread, and transmission of this opportunistic pathogen. While contact with other people presents opportunities for pathogen exposure and transmission, diversity of social connections may be protective against pathogens such as the common cold. This study examined whether social relationship resources, including the amount and diversity of social contacts, are associated with S. aureus colonization. Participants were community members (N = 443; 68% Hispanic) in naturally occurring social groups in southwestern Arizona. Four types of social relationships and loneliness were assessed, and samples from the skin, nose and throat were obtained to ascertain S. aureus colonization. Overall S. aureus prevalence was 64.8%. Neither the amount nor the diversity of social contacts were associated with S. aureus colonization. The concurrent validity of the social relationship assessments was supported by their moderate intercorrelations and by their positive association with self-rated health. The results suggest that the association of social network diversity and susceptibility to the common cold does not extend to S. aureus colonization. Conversely, colonization prevalence was not higher among those with more social contacts. The latter pattern suggests that social transmission may be relatively infrequent or that more intimate forms of social interaction may drive transmission and colonization resulting in high community prevalence of S. aureus colonization. These data inform communicable disease control efforts.

A Quantitative Assessment of Staphylococcus aureus Community Carriage in Yuma, Arizona.

BACKGROUND: Disease control relies on pathogen identification and understanding reservoirs. Staphylococcus aureus infection prevention is based upon decades of research on colonization and infection, but diminishing returns from mitigation efforts suggest significant knowledge gaps. Existing knowledge and mitigation protocols are founded upon culture-based detection, with almost no information about pathogen quantities. METHODS: We used culture and a quantitative polymerase chain reaction assay on samples from 3 body sites to characterize colonization more comprehensively than previous studies by describing both prevalence and pathogen quantity. RESULTS: We show a much higher overall prevalence (65.9%) than previously documented, with higher quantities and prevalence associated with the nares, non-Hispanic males (86.9%), and correlating with colonization in other body sites. These results suggest that research and clinical practices likely misclassify over half of colonized persons, limiting mitigation measures and their impact. CONCLUSIONS: This work begins the process of rebuilding foundational knowledge of S aureus carriage with more accurate and wholistic approaches.

Injuries and Illnesses Across 10 Years of Canada Games Competitions: 2009 - 2019.

Background: The Canada Games are a national level competition held every two years alternating between Summer and Winter Games. Participation in elite level athletics, like the Canada Games, have an inherent risk of injury and illness. Purpose: To analyze the incidence and characteristics of injuries and illnesses during Canada Games competitions from 2009-2019 (primarily) and to understand sex differences in odds of musculoskeletal injury for Summer and Winter Canada Games athletes (secondarily). Study Design: Descriptive Epidemiology Study. Methods: Using a retrospective cohort, data were abstracted from medical incident reports generated during Canada Games from 2009 - 2019. Data were coded for body part injured and injury type or illness system; injuries were also categorized as acute or chronic. Results: Across all 10 years of competition, 3160 injuries reported in 8710 male athletes and 3272 injuries reported in 8391 female athletes. Injury incidence was 362.8 and 389.9 and illness incidence was 47.8 and 64.5 per 1000 male and female athletes, respectively. Female athletes had a 1.12 (95% CI: 1.06; 1.19) greater odds of injury and 1.37 (95% CI: 1.20; 1.57) greater odds of illness compared to male athletes. Overall, injury (399.31 vs. 360.31; p < 0.001) and illness (68.67 vs. 47.30; p < 0.001) incidences were higher in Winter Games, compared to Summer Games, per 1000 athletes. When comparing male and female athletes participating in similar sports, sex specific differences exist in odds of both injury and illness. Conclusions: Male and female athletes competing in Canada Games competitions demonstrate differences in injury and illness incidence and odds of injury. This suggests a need to examine if additional modifiable risk factors may exist, which could contribute to prevention strategies to reduce injury and illness during Canada Games competition. Level of Evidence: 3.

Hybrid effectiveness-implementation study designs in sports injury prevention research.

Despite vast evidence supporting the effectiveness of lower extremity injury prevention programs in a variety of sport settings, age groups, and levels of competition, there is limited evidence on implementation strategies that positively impact the feasibility, scale-up and sustainability of such programs. Sport-related injury prevention is affected by the research-to-practice gap, a pervasive issue in healthcare, where high-quality experimental research is not used in routine clinical practice. An intervention shown to be efficacious in a controlled environment, such as a lab or in a field-study conducted by scientists, will demonstrate a decline in benefit when implemented in the intended clinical setting. Real-world considerations, such as foundational knowledge and training, time constraints, or end user motivation, influence the quality and consistency of implementation. Acknowledging and addressing implementation barriers in a systematic way is essential to promote effective program dissemination. Study design methods that measure both clinical effectiveness and implementation strategies need to be identified. Hybrid effectiveness-implementation designs simultaneously measure both an intervention's effect on clinical outcomes as well as critical information related to implementation strategy; however these study designs are not frequently utilized. The purpose of this mini-review is to describe: the basics of hybrid designs, rationale for using hybrid designs, and examples of how these designs could be used in athletic healthcare injury prevention research.

Secondary School Athletic Trainers' Experiences With Organizational Conflict: A Comparison Across Employment Models.

CONTEXT: Athletic training is a multifaceted profession characterized by interpersonal relationships and a team approach to care. Collaborative relationships, by nature, open the door to conflict, which has been reported frequently in the collegiate athletic setting. However, secondary school athletic trainers' (ATs') experiences with conflict and pressure in their role are not readily understood. OBJECTIVE: To measure the extent and sources of stress, pressure, and conflict within the secondary school athletic training setting and determine if differences exist across employment characteristics. DESIGN: Cross-sectional study. SETTING: Secondary school athletics. PATIENTS OR OTHER PARTICIPANTS: Secondary school ATs (n = 725, age = 39.8 ± 10.5 years, years certified = 16.7 ± 9.7, years in current role = 10.6 ± 7.8). MAIN OUTCOME MEASURES: Participants were asked to reply to an online questionnaire with quantitative measures pertaining to organizational conflict and workplace dynamic. Employment type (school district employee, school district teacher, medical or university facility, independent contractor) and status (full time, part time) served as independent variables. Likert-scale scores (1 = strongly agree to 5 = strongly disagree; 1 = always to 5 = never) and perceived sources of stress, pressure, and conflict were the dependent variables. Analyses consisted of Kruskal-Wallis tests with Mann-Whitney U post hoc tests and odds ratios to assess associations between variables of interest. RESULTS: We obtained a 15.3% response rate (725/4745). Although the ATs reported experiencing conflict and pressure, these experiences were relatively infrequent and not universal. Compared with part-time ATs, full-time ATs described higher ratings of strong relationships with coaches (P = .003) and principals (P = .002). The most frequently identified sources of conflict were parents (59%) and coaches (53.9%), followed by athletes (32.6%). Full-time ATs were 1.6 times more likely to report experiencing conflict with a coach than part-time ATs (odds ratio = 1.550, 95% CI = 1.037, 2.317; P = .040). CONCLUSIONS: Secondary school ATs' experiences regarding organizational conflict were relatively positive. Instances of pressure and conflict were noted, though relatively infrequently, and these experiences were largely uninfluenced by employment type.

Building Research Infrastructure: The Development of a Technical Assistance Group-Service Center at an RCMI.

As one of the Research Centers for Minority Institutions (RCMI), the Southwest Health Equity Research Collaborative (SHERC) worked over the first five-year period of funding to foster the advancement of Early Stage Investigators, enhance the quality of health disparities research, and increase institution research capacity in basic Biomedical, Behavioral, and/or Clinical research; all priorities of RCMIs. In year 4, the Technical Assistance Group-Service Center (TAG-SC) was created to help achieve these goals. The TAG-SC provides one-on-one investigator project development support, including research design, data capture, and analysis. Successful implementation of the TAG-SC was tracked using Research Electronic Data Capture (REDCap), a secure, web-based software platform allowing for immediate tracking and evaluation processes. In the first two years, 86 tickets were submitted through the REDCap system for methodological support by TAG-SC experts (faculty and staff) for assistance with health-equity related research, primarily SHERC and externally funded Social/Behavioral research projects. The TAG-SC increased the research capacity for investigators, especially within the SHERC. In this manuscript, we describe the methods used to create the TAG-SC and the REDCap tracking system and lessons learned, which can help other RCMIs interested in creating a similar service center offering an innovative way to build methodological infrastructure.

Adverse Childhood Experiences in relation to drug and alcohol use in the 30 days prior to incarceration in a county jail.

Purpose: To characterize the relationship between adverse childhood experiences (ACEs) and substance use among people incarcerated in a county jail. Design/methodology/approach: A questionnaire was administered to 199 individuals incarcerated in a Southwest county jail as part of a social-epidemiological exploration of converging co-morbidities in incarcerated populations. Among 96 participants with complete ACEs data, the authors determined associations between individual ACEs items and a summative score with methamphetamine (meth), heroin, other opiates, and cocaine use and binge drinking in the 30 days prior to incarceration using logistic regression. Findings: People who self-reported use of methamphetamine, heroin, other opiates, or cocaine in the 30 days prior to incarceration had higher average ACEs scores. Methamphetamine use was significantly associated with living with anyone who served time in a correctional facility and with someone trying to make them touch sexually. Opiate use was significantly associated with living with anyone who was depressed, mentally ill, or suicidal; living with anyone who used illegal street drugs or misused prescription medications; and if an adult touched them sexually. Binge drinking was significantly associated with having lived with someone who was a problem drinker or alcoholic. Originality: Significant associations between methamphetamine use and opiate use and specific adverse childhood experiences suggest important entry points for improving jail and community programming. Social Implications: Our findings point to a need for research to understand differences between methamphetamine use and opiate use in relation to particular adverse experiences during childhood, and a need for tailored intervention for people incarcerated in jail.

Improper Fit in American Youth Football Helmets Across One Competitive Season.

Improper helmet fit is related to sport-related concussion symptomology. The objective of this study was to determine the prevalence of improperly fit helmets in American youth tackle football players across one competitive season. Four recreation leagues including 147 players (45.2 ± 14.7 cm, 147.5 ± 9.0 kg), aged 7-12 years, participated in pre-season and post-season data collection timepoints. Participant and league demographics were collected at pre-season. Helmet fit was assessed at pre- and post-season using a 13-item checklist. A helmet was defined as improperly fit if failed to comply with or more of the checklist items. Most players (84%) rented helmets from the league. At preseason, 71.4% of helmets, and at post-season 79.6%, were improperly fit with no significant change over time (p = 0.14). Of the 105 improperly fit helmets at the start of the season, 61% were still considered improperly fit at post season. The 11-12 year old age group had significantly more improperly fit helmets than the 7-10 year old age group at post-season (p = 0.033), but not pre-season (p = 0.655). American youth football players depend on the league to fit their helmet. Most players did not meet at least one checklist criteria. Helmets improperly fit at preseason were still not fit at post.

Cardiovascular Risk Factors among Individuals Incarcerated in an Arizona County Jail.

We aimed to estimate the prevalence of cardiovascular risk factors, including hypertension, diabetes, high cholesterol, cigarette smoking, alcohol consumption, and obesity among a sample of individuals incarcerated in an Arizona county jail and compare prevalence estimates to a matched non-institutionalized population. From 2017-2018, individuals housed at a county jail completed a cross-sectional health survey. We estimated the prevalence of hypertension, diabetes, cholesterol, overweight/obesity, cigarette smoking, binge drinking, and self-reported health among individuals incarcerated. We compared prevalence estimates of cardiovascular risk factors to a matched sample of 2017-2018 NHANES participants. Overall, 35.9%, 7.7%, and 17.8% of individuals incarcerated in jail self-reported hypertension, diabetes, and high cholesterol, respectively. Of individuals incarcerated, 59.6% were overweight or obese and 36.8% self-reported fair or poor general health. Over half of individuals incarcerated reported ever smoking cigarettes (72.3%) and binge drinking (60.7%). Compared to a matched sample of NHANES participants, individuals incarcerated in jail had a statistically higher prevalence of cigarette smoking and binge drinking. Screening of cardiovascular risk factors and providing preventive measures and interventions, such as healthy eating, physical activity, or pharmacological adherence interventions, while individuals are incarcerated may contribute to the prevention and management of cardiovascular risk factors and, eventually, cardiovascular disease.

The Effect Of Mild Exercise Induced Dehydration On Sport Concussion Assessment Tool 3 (SCAT3) Scores: A within-subjects design.

BACKGROUND: Sports-related concussions are prevalent in the United States. Various diagnostic tools are utilized in order to monitor deviations from baseline in memory, reaction time, symptoms, and balance. Evidence indicates that dehydration may also alter the results of diagnostic tests. PURPOSE: The purpose was to determine the effect of exercise-induced dehydration on performance related to concussion examination tools. STUDY DESIGN: Repeated measures design. METHODS: Seventeen recreationally competitive, non-concussed participants (age: 23.1±3.1 years, height:168.93±10.71 cm, mass: 66.16 ± 6.91 kg) performed three thermoneutral, counterbalanced sessions (rested control, euhydrated, dehydrated). Participants were either restricted (0.0 L/hr) or provided fluids (1.0 L/hr) while treadmill running for 60 min at an intensity equal to 65-70% age-predicted maximum heart rate (APMHR). The Sport Concussion Assessment Tool 3 (SCAT3) was utilized to assess symptoms, memory, balance, and coordination. RESULTS: Statistically significant differences were seen among sessions for symptom severity and symptom total. The rested control session had significantly lower values when compared to the dehydrated session. Additionally, the symptom total in the rested control was significantly lower than the euhydrated condition as well. No statistically significant differences were seen for the BESS or memory scores. CONCLUSIONS: Mild exercise-induced dehydration results in increased self-reported symptoms associated with concussions. Clinicians tasked with monitoring and accurately diagnosing head trauma should take factors such as hydration status into account when assessing patients for concussion with the SCAT3. Clinicians should proceed with caution and not assume concussion as primary cause for symptom change. LEVEL OF EVIDENCE: Level 3.

Reliability of the Tuck Jump Assessment Using Standardized Rater Training.

BACKGROUND: The Tuck Jump Assessment (TJA) is a test used to assess technique flaws during a 10-second, high intensity, jumping bout. Although the TJA has broad clinical applicability, there is no standardized training to maximize the TJA measurement properties. HYPOTHESIS/PURPOSE: To determine the reliability of the TJA using varied healthcare professionals following an online standardized training program. The authors hypothesized that the total score will have moderate to excellent levels of intra- and interrater reliability. STUDY DESIGN: Cross-sectional reliability. METHODS: A website was created by a physical therapist (PT) with videos, written descriptors of the 10 TJA technique flaws, and examples of what constituted no flaw, minor flaw, or major flaw (0,1,2) using published standards. The website was then validated (both face and content) by four experts. Three raters of different professions: a PT, an AT, and a Strength and Conditioning Coach Certified (SCCC) were selected due to their expertise with injury and movement. Raters used the online standardized training, scored 41 videos of participants' TJAs, then scored them again two weeks later. Reliability estimates were determined using intraclass correlation coefficients (ICCs) for total scores of 10 technique flaws and Krippendorff α (K α) for the individual technique flaws (ordinal). RESULTS: Eleven of 50 individual technique flaws were above the acceptable level (K α = 0.80). The total score had moderate interrater reliability in both sessions (Session 1: ICC2,2 = 0.64; 95% CI (Confidence Interval) (0.34-0.81); Standard Error Measurement (SEM) = 0.66 technique flaws and Session 2: ICC2,2 = 0.56; 95% CI (0.04-0.79); SEM = 1.30). Rater 1had a good reliability (ICC2,2 = 0.76; 95% CI (0.54-0.87); SEM = 0.26), rater 2 had a moderate reliability (ICC2,2 = 0.62; 95% CI (0.24-0.80); SEM =0.41) and rater 3 had excellent reliability (ICC2,2 = 0.98; 95% CI (0.97-0.99); SEM =0.01). CONCLUSION: All raters had at least good reliability estimates for the total score. The same level of consistency was not seen when evaluating each technique flaw. These findings suggest that the total score may not be as accurate when compared to individual technique flaws and should be used with caution. LEVEL OF EVIDENCE: 3b.

The Effect of Lacrosse Protective Equipment on Cardiopulmonary Resuscitation and Automated External Defibrillator Shock.

CONTEXT: In the event of an acute cardiac event, on-field equipment removal is suggested, although it remains unknown how lacrosse equipment removal may alter time to first chest compression and time to first AED shock. OBJECTIVE: To determine time to first chest compression and first AED shock in 2 chest exposure procedures with 2 different pad types. DESIGN: Crossover study Setting: Simulation laboratory Participants: Thirty-six athletic trainers (21 females, 15 males; age=30.58±7.81) Main Outcome Measures: Participants worked in pairs to provide 2 rescuer CPR intervention on a simulation manikin (QCPR manikin, Laerdal Medical, Wappingers Falls, NY) outfitted with lacrosse pads and helmet. Participants completed a total of 8 trials per pair (2 chest exposure procedures X 2 pad types X 2 participant roles). The dependent variables were time to first compression (s) and time to first AED shock (s). The independent variables were chest exposure procedure with 2 levels (procedure 1: removal of helmet while initiating CPR over the pads followed by pad retraction and AED application; procedure 2: removal of helmet and removal of pads followed by CPR and AED application) and pad type (Warrior Burn Hitman shoulder pads; Warrior Nemesis chest protector). RESULTS: We found a statistically significant interaction between chest exposure procedure and pad type for time to first compression (F1,35=4.66, P=0.04, ω2p=0.10) with significantly faster times during procedure 1 for both the Nemesis pads (16.1±3.4 s) and the Hitman pads (16.1±4.5 s) compared to procedure 2 (Nemesis pads: 49.6±12.9 s, P<0.0001; Hitman pads: 53.8±14.5 s, P<0.0001). CONCLUSIONS: Completing the initial cycle of chest compressions over either shoulder pads or a chest protector hastens time to first chest compression without diminishing CPR quality which may improve patient outcomes. Time to first AED shock was not different between equipment procedure or pad type.

Educational Attainment and Staphylococcus aureus Colonization in a Hispanic Border Community: Testing Fundamental Cause Theory.

This study was carried out to evaluate hypotheses generated by fundamental cause theory regarding the socioeconomic status (SES) gradient in colonization with Staphylococcus aureus among Hispanic and non-Hispanic adults living in a border community. Participants (n = 613) recruited in naturally occurring small groups at public and private sites throughout Yuma County, AZ, completed a sociodemographic survey and swabbed their palms, noses, and throats to sample microbial flora. Positive S. aureus colonization among non-Hispanic white participants was nominally higher (39.0%; 95% confidence interval [CI] = 32.4 to 46.1%) than that in Hispanics (31.3%; 95% CI = 26.4 to 36.8%), but there was no education gradient for the sample overall (incidence rate ratio = 1.00; 95% CI = 0.90 to 1.12) or within each ethnic group separately. The education gradient between Hispanic and non-Hispanic whites was statistically equivalent. Results were consistent when home ownership was used as the SES indicator. These data show that S. aureus colonization is not linked to two different SES indicators or Hispanic ethnicity. S. aureus colonization may be considered a less preventable health risk that is outside the influence of SES-based resources.IMPORTANCE Unlike some types of S. aureus infections, S. aureus colonization is not associated with ethnicity or educational attainment and thus may be outside the influence of socioeconomic status-based resources typically mobilized to avoid or mitigate preventable health risks. This assessment of a clinically silent risk that usually precedes infections may illustrate a boundary of fundamental cause theory.

The Association Between the Single Leg Hop Test and Lower-Extremity Injuries in Female Athletes: A Critically Appraised Topic.

Clinical Scenario: Female college student-athletes (SA) often experience time loss from musculoskeletal injuries to the lower extremities. This can lead to lengthy rehabilitation, expensive medical bills, and declines in health-related quality of life. Identifying at-risk athletes prior to the start of an athletic season may allow coaches or athletic trainers to prescribe an injury prevention program. Clinical Question: In female college SA, are preseason single leg hop (SLH) scores associated with identifying those at risk for lower-extremity musculoskeletal injuries? Summary of Key Findings: Five prospective cohort studies in female SA scored athletes on the SLH prior to the start of the athletic sport season. One of 5 studies found an association of SLH with injury risk. An additional 2 studies found that the SLH as part of a battery of functional performance tests was associated with injury risk in some anatomic locations (eg, thigh/knee), but not overall injury risk. Clinical Bottom Line: Methodological limitations of the reviewed studies limits a final conclusion, and there is insufficient evidence to determine if the SLH should be used as a sole functional performance test to identify at-risk female SA; it may be useful as part of a battery of functional performance tests for female college SA. Strength of Recommendation: All studies were prospective cohort studies (level 3).

Impact Mitigation Properties of Women's Lacrosse Headgear.

Recently, protective headgear has been released for women's lacrosse despite the fact that contact to the head is illegal. The purposes of this study were to (1) compare the linear and rotational impact attenuation properties of 2 brands of lacrosse headgear at 4 different locations during laboratory pendulum impacts and (2) determine impact dissipation of new and used lacrosse headgear. We measured peak rotational acceleration (PRA; rad/s2) and linear acceleration (PLA; g) at 4 impact locations (side, rear boss non-centric (NC), front boss, and front) in two headgear brands (Cascade LX, Hummingbird). Two headgear service lives (new headgear, used headgear) were included for the second analysis. During the slower speed, there was a significant interaction between impact location and helmet brand (p = 0.002) for PLA. No other findings were significant. While the Hummingbird headgear reduced linear and rotational accelerations of the headform better than the Cascade headgear during slow velocity impacts to the front and front boss locations, it did so due to extreme motion of the helmet upon impact that we believe may compromise protection of the head and face from lacerations and other injuries.
