ObjectivesTo determine the effect of heading a soccer ball on serum neurofilament light (NF-L) protein, plasma tau protein and symptom metrics including total number of symptoms reported and symptom severity scores on the Standardized Concussion Assessment Tool— 3rd edition (SCAT3).MethodsEleven male collegiate soccer players were recruited to take part in three experimental conditions including heading, sham and control conditions. Participants were required to perform 40 headers in 20 min in the heading condition, and control 40 soccer balls directed at them with their hands, chest or thigh in the sham condition. No ball contact was made during the control condition. Blood sampling and SCAT3 symptom assessments were completed prior to and 1 hour following conditions. A subset of participants returned 3 weeks following the heading condition for blood sampling.ResultsNF-L was elevated at 1 hour (p=0.004) and 1 month (p=0.04) following the heading condition, and at 1 hour (p=0.02) following the control condition. Tau levels remained unchanged following all conditions. The total number of symptoms (TS) and symptom severity (SS) scores from the SCAT3 were both elevated following the heading condition (p=0.01 and p=0.03, respectively). Both TS and SS decreased following sham (p=0.04 and p=0.04) and control conditions (p=0.04 and p=0.04).ConclusionAn acute bout of soccer heading is associated with increased NF-L concentrations at 1 hour and 1 month following the session and can lead to symptoms commonly reported following sport-related concussion.

Severity Scores

Background: Organizations recommend that athletes should be asymptomatic or symptom-limited before initiating a graduated return-to-play (GRTP) protocol after sports-related concussion, although asymptomatic or symptom-limited is not well-defined. Hypotheses: (1) There will be a range (ie, beyond zero as indicator of “symptom-free”) in symptom severity endorsement when athletes are deemed ready to initiate a GRTP protocol. (2) Baseline symptom severity scores and demographic/preinjury medical history factors influence symptom severity scores at the commencement of the GRTP protocol. (3) Greater symptom severity scores at GRTP protocol initiation will result in longer protocol duration. (4) Symptom severity scores will not differ between those who did and did not sustain a repeat injury within 90 days of their initial injury. Study Design: Cohort study; Level of evidence, 2. Methods: Across 30 universities, athletes (N = 1531) completed assessments at baseline and before beginning the GRTP protocol, as determined by local medical staff. Symptom severity scores were recorded with the symptom checklist of the Sport Concussion Assessment Tool–3rd Edition. Nonparametric comparisons were used to examine the effect of medical, demographic, and injury factors on symptom endorsement at GRTP protocol initiation, as well as differences in symptom severity scores between those who did and did not sustain a repeat injury within 90 days. A Cox regression was used to examine the association between symptom severity scores at GRTP protocol initiation and protocol duration. Results: Symptom severity scores at the time when the GRTP protocol was initiated were as follows: 0 to 5 (n = 1378; 90.0%), 6 to 10 (n = 76; 5.0%), 11 to 20 (n = 42; 3.0%), and ≥21 (n = 35; 2.0%). Demographic (sex and age), medical (psychiatric disorders, attention-deficit/hyperactivity disorder, learning disorder), and other factors (baseline symptom endorsement and sleep) were significantly associated with higher symptom severity scores at the GRTP initiation ( P < .05). The 4 GRTP initiation time point symptom severity score groups did not significantly differ in total time to unrestricted RTP, χ2(3) = 1.4; P = .73. When days until the initiation of the GRTP protocol was included as a covariate, symptom severity scores between 11 and 20 ( P = .02; hazard ratio = 1.44; 95% CI, 1.06-1.96) and ≥21 ( P < .001; hazard ratio = 1.88; 95% CI, 1.34-2.63) were significantly associated with a longer GRTP protocol duration as compared with symptom severity scores between 0 and 5. Symptom severity scores at GRTP initiation did not significantly differ between those who sustained a repeat injury within 90 days and those who did not ( U = 29,893.5; P = .75). Conclusion: A range of symptom severity endorsement was observed at GRTP protocol initiation, with higher endorsement among those with higher baseline symptom endorsement and select demographic and medical history factors. Findings suggest that initiation of a GRTP protocol before an absolute absence of all symptoms is not associated with longer progression of the GRTP protocol, although symptom severity scores >10 were associated with longer duration of a GRTP protocol. Results can be utilized to guide clinicians toward optimal GRTP initiation (ie, balancing active recovery with avoidance of premature return to activity).

Balance Error

Context: Capturing baseline data before a concussion can be a valuable tool in individualized care. However, not all athletes, including dancers, have access to baseline testing. When baseline examinations were not performed, clinicians consult normative values. Dancers are unique athletes; therefore, describing values specific to dancers may assist those working with these athletes in making more informed decisions.Objective: To describe values for key concussion measures of dancers. Our secondary aim was to examine whether differences existed between sexes and professional status. Finally, we explored factors that may affect dancers' scores.Design: Cross-sectional study.Setting: Professional dance companies and a collegiate dance conservatory.Patients or Other Participants: A total of 238 dancers (university = 153, professional = 85; women = 171; men = 67; age = 21.1 ± 4.8 years).Main Outcome Measure(s): We calculated the total symptom severity from the Sport Concussion Assessment Tool–3rd edition; the Standardized Assessment of Concussion score; the modified Balance Error Scoring System score; and the King-Devick score for each participant. Group differences were analyzed with Mann-Whitney or t tests, depending on the data distribution. We used bivariate correlations to explore the effects of other potential influencing factors.Results: Participants demonstrated the following baseline outcomes: symptom severity = 16.6 ± 12.8; Standardized Assessment of Concussion = 27.5 ± 1.8; modified Balance Error Scoring System = 3.2 ± 3.1 errors; and King-Devick = 41.5 ± 8.2 seconds. A Mann-Whitney test revealed differences in King-Devick scores between female (40.8 ± 8.0 seconds) and male (43.4 ± 8.4 seconds) dancers (P = .04). An independent-samples t test also demonstrated a difference in modified Balance Error Scoring System scores between female (2.95 ± 3.1 errors) and male (3.8 ± 3.1 errors) dancers (P = .02). Age, hours of sleep, height, and history of concussion, depression, or injury did not display moderate or strong associations with any of the outcome measures.Conclusions: Dancers' symptom severity scores appeared to be higher than the values reported for other athletes. Additional studies are needed to establish normative values and develop a model for predicting baseline scores.

Abstract Objective The Sport Concussion Assessment Tool (SCAT), fifth Edition, Symptom Evaluation (S5SE) differs from previous versions by having examinees report trait (i.e. “typical” feelings) as opposed to state (i.e., “how you feel right now”) concussion-like symptoms at baseline. This study assessed differences among, and convergent validity of, scores on the S5SE, SCAT3 Symptom Evaluation (S3SE), and the Brief Symptom Inventory (BSI-18). Methods A total of 113 University of Florida varsity athletes completed symptom questionnaires on the same day in a counterbalanced administration. The final sample consisted of 94 participants (mean age ± SD = 18.4 ± 0.8 years, 57% male, 65% white) from 17 sports. We assessed convergent validity using Spearman rank-order correlations. Within-participant differences were analyzed with Wilcoxon Signed-Rank tests. We qualitatively described free-response answers to the S5SE question that asks, “if not feeling 100%, why?”. Results S5SE total severity score demonstrated adequate convergent validity with both the S3SE (rho = .407, p &lt; .001) and BSI-18 (rho = .432, p &lt; .001). Domain-specific analyses indicated variable convergent validity (rho &lt; 0.4 to rho &gt; 0.6). Severity scores did not differ between the S3SE and S5SE (p = .500), but 24.5% of participants reported S3SE &gt; S5SE and 34.0% S5SE &gt; S3SE. Three themes emerged from qualitative examination of reasons for “not feeling 100%”: (1) tiredness/sleep, (2) adjustment difficulties, and (3) academic/athletic stress. Conclusions Adequate convergent validity exists between SCAT5 and SCAT3 symptom severity in collegiate athletes. However, most examinees report different baseline symptom severity when asked to describe their trait (S5SE) versus state symptoms (S3SE). Clinicians should consider using the new SCAT5 Symptom Evaluation as a screening tool for identifying otherwise healthy or “undiagnosed” individuals who would benefit from targeted interventions.

This study determined the effects of a single sled push at different loads on sprint performance in competitive male soccer players. Twenty male competitive outfield soccer players (age 19.6±1.3y, body mass 73.6±8.2kg) were split into experimental (n=10) and control groups. In the experimental group, 20m linear sprint time was measured immediately before and 5, 6 and 7minutes after the sled push with either 50 or 100% body mass. The control group performed the 20m sprints only. A repeated measures ANOVA comparing control and experimental groups revealed no effects of time, group or time by group interaction for either experimental condition (all P>0.05). The repeated measures ANOVA compared the experimental conditions revealed effects of time (P=0.034) and group (P=0.002), but not time by group (P>0.05). The effects sizes demonstrated within group effects on sprint time that were small to moderate (-0.26 to 0.71) and trivial to small (-0.31 to 0.09) for the 50% and 100% body mass condition, respectively. These findings demonstrate that a sled push has no significant effect on 20 m sprint time in competitive footballers. If coaches continue to prescribed a sled push before sprinting, a single 15 m push with 50% body mass could have positive benefits.

Twenty commercially available oenological tannins (including hydrolysable and condensed) were assessed for their antiradical/reducing activity, comparing two analytical approaches: The 2,2-diphenyl-1-picrylhydrazyl (DPPH•) radical scavenging spectrophotometric assay and the cyclic voltammetry (CV) electrochemical method. Electrochemical measurements were performed over a −200 mV–500 mV scan range, and integrated anodic currents to 500 mV were used to build a calibration graph with (+)-catechin as a reference standard (linear range: From 0.0078 to 1 mM, R2 = 0.9887). The CV results were compared with the DPPH• assay (expressed as % of radical scavenged in time), showing high correlation due to the similarity of the chemical mechanisms underlying both methods involving polyphenolic compounds as reductants. Improved correlation was observed by increasing the incubation time with DPPH• to 24 h (R2 = 0.925), demonstrating that the spectrophotometric method requires a long-term incubation to complete the scavenging reaction when high-molecular weight tannins are involved; this constraint has been overcome by using instant CV measurements. We concluded that the CV represents a valid alternative to the DPPH• colorimetric assay, taking advantage of fast analysis and control on the experimental conditions and, because of these properties, it can assist the quality control along the supply chain.

Background: Current recommendations for sport-related concussion uniformly emphasize the importance of physical activity. However, specifics of this recommendation remain vague and do not account for an exercise dosage or compliance. Purposes: First, we examined if an 8-week individualized sub-symptom threshold aerobic exercise prescription, initiated within the first two weeks of concussion, alleviates symptom severity or affects the amount of exercise performed during the study. Second, we examined whether prescription adherence, rather than randomized group assignment, reflects the actual impact of aerobic exercise in post-concussion recovery. Methods: For this single-site prospective randomized clinical trial, participants completed an aerobic exercise test within 14 days of injury, and were randomized to an individualized aerobic exercise program or standard-of-care, and returned for assessments 1 month and 2 months after the initial visit (Table 1). The aerobic exercise group was instructed to exercise 5 days/week, 20 minutes/day, at a target heart rate based on an exercise test at the initial visit. Participants reported their symptom exercise volume each week over the 8-week study period, and reported symptoms at each study visit (initial, 1 month, 2 month). Results: Initial symptom severity was not different between randomized groups (Figure 1A), and no significant differences in symptom severity were found at the 4-week (Figure 1B) or 8-week (Figure 1C) assessment. In addition, there was no significant differences between groups for average weekly exercise volume during the first four weeks (Figure 2A) or second four weeks (Figure 2B) of the study. During the first four weeks of the study, 65% (n=11/17) of the exercise intervention participants were compliant with their exercise recommendation (≥100 min/week), compared to 45% (n=9/20) of the standard-of-care group (p=0.33). During the second four weeks of the study, 71% (n=12/17) of the exercise prescription group exercised ≥100 min/week, compared to 55% (n=11/20) of the standard-of-care group (p=0.50). When grouped by exercise volume, the group who exercised ≥100 minutes/week during the first month of the study reported significantly lower symptom severity scores than those who exercised <100 minutes/week (Figure 3B), despite similar initial symptom severity scores (Figure 3A). Conclusion: Participant randomization within 14 days of concussion did not lead to a significant reduction in symptoms, or greater exercise volume. Given that greater exercise volume was associated with lower symptoms after one month of the study, researchers and clinicians should pay particular attention to adherence to aerobic exercise programs for the treatment of concussion.

Abstract Bovine respiratory disease (BRD) is the leading natural cause of death in US beef and dairy cattle, causing the annual loss of more than 1 million animals and financial losses in excess of $700 million. The multiple etiologies of BRD and its complex web of risk factors necessitate a herd-specific intervention plan for its prevention and control on dairies. Hence, a risk assessment is an important tool that producers and veterinarians can utilize for a comprehensive assessment of the management and host factors that predispose calves to BRD. The current study identifies the steps taken to develop the first BRD risk assessment tool and its components, namely the BRD risk factor questionnaire, the BRD scoring system, and a herd-specific BRD control and prevention plan. The risk factor questionnaire was designed to inquire on aspects of calf-rearing including management practices that affect calf health generally, and BRD specifically. The risk scores associated with each risk factor investigated in the questionnaire were estimated based on data from two observational studies. Producers can also estimate the prevalence of BRD in their calf herds using a smart phone or tablet application that facilitates selection of a true random sample of calves for scoring using the California BRD scoring system. Based on the risk factors identified, producers and herd veterinarians can then decide the management changes needed to mitigate the calf herd's risk for BRD. A follow-up risk assessment after a duration of time sufficient for exposure of a new cohort of calves to the management changes introduced in response to the risk assessment is recommended to monitor the prevalence of BRD.

Past research showed that social networking sites represent perfect platforms to satisfy narcissistic needs. The present study aimed to investigate how grandiose (GN) and vulnerable narcissism (VN) as well as social comparisons are associated with Facebook activity, which was measured with a self-report on three activity dimensions: Acting, Impressing, and Watching. In addition, the state self-esteem (SSE) was measured with respect to performance, social behavior, and appearance. One hundred and ten participants completed an online survey containing measures of SSE and Facebook activity and a priming procedure with three experimental conditions embedded in a social media context (upward comparison, downward comparison, and control group). Results indicated, as expected, that high VN was negatively associated with SSE on each subscale and the overall score. In addition, it was found that VN, but not GN, displayed positive associations with frequency of Facebook activities. Finally, it was proposed and confirmed that VN in interaction with the priming of downward comparisons negatively affected SSE. The conclusion drawn is that VN represents a key variable for the prediction of self-esteem as well as for the frequency of Facebook activity.

The aim of the study is to evaluate the preparedness of retirement and nursing homes in the city of Sassari at the end of the first wave of the severe acute respiratory syndrome coronavirus 2 epidemic, first by investigating the risk perception of epidemic outbreaks by the facility managers and subsequently by carrying out a field assessment of these facilities. To perform the field assessment, a checklist developed by the CDC (Infection Prevention and Control Assessment Tool for Nursing Homes Preparing for COVID-19) and adapted to the Italian context was used. Fourteen facilities took part in the survey (87.5%). The application of good practices for each survey area was expressed as a percentage with the following median values: restriction policies (87.5%), staff training (53.8%), resident training (67.6%), availability of personal protective equipment (41.7%), infection control practices (73.5%) and communication (80%). Among the facilities, considerable variability was observed in these evaluation fields: only the restriction policies and communication activities were applied uniformly. A discrepancy was found between perceived risk and real danger in the facilities, requiring targeted communication actions. At present, it is necessary to promote a new approach based on the prediction of critical events, thereby providing the means to effectively address them.

Brompheniramine Maleate

This was a double-blind, randomized, placebo-controlled, multicenter, parallel study comparing the effectiveness, at recommended doses, of an extended-release formulation of brompheniramine maleate and terfenadine in the treatment of allergic rhinitis. Subjects with symptoms of seasonal and/or perennial allergic rhinitis received brompheniramine 12 mg (n = 106), 8 mg (n = 105), terfenadine 60 mg (n = 106), or placebo (n = 53) twice daily for 14 days. On treatment days 3, 7, and 14, symptom severity ratings (i.e., rhinorrhea, sneezing, nasal congestion, itchy nose, eyes or throat, excessive tearing, postnasal drip) were completed by the physician; subjects and physicians each completed a global efficacy evaluation. Brompheniramine 12 mg and 8 mg and terfenadine were more effective than placebo (p ≤ 0.05) on the physicians’ global; brompheniramine 12 mg was more effective than terfenadine (p ≤ 0.05) on days 7 and 14 and brompheniramine 8 mg on day 3. On the subjects’ global evaluation, brompheniramine 12 mg and 8 mg and terfenadine were more effective than placebo (p ≤ 0.05); brompheniramine 12 mg was more effective than terfenadine (p ≤ 0.05) on days 7 and 14 and brompheniramine 8 mg on day 3. In general, brompheniramine 8 mg was comparable to terfenadine. On days 3 and 7, the total symptom and total nasal symptom severity scores for subjects receiving brompheniramine 12 mg were significantly more improved than for placebo (p < 0.05); terfenadine was not different from placebo; brompheniramine 12 mg was significantly better than terfenadine on day 7 (p < 0.05) for reducing total symptom severity and on days 3, 7, and 14 for reducing total nasal symptom severity. Adverse experiences were reported by 155 (41.9%) of the 370 subjects enrolled in the study. The overall rate of adverse experiences in the brompheniramine 12 mg treatment group (57.5%) was significantly greater (p < 0.05) than for brompheniramine 8 mg (38.1%), terfenadine (31.1%), and placebo (39.6%). In conclusion, an extended-release formulation of brompheniramine 12 mg or 8 mg bid alleviates allergic rhinitis symptoms and brompheniramine 12 mg provides significantly better relief of these symptoms than terfenadine 60 mg bid.
