IntroductionFerritin has been implicated in body physiology and pathology. Smoking cigarettes (Cg) alters ferritin metabolism. Waterpipe (Wp) smoking has recently reemerged as a global epidemic and is linked to the most devas�tating diseases. However, the effect of smoking Wp on ferritin is not known. Therefore, the current study compared plasma ferritin in adolescents smok�ing Cg, Wp, both (CgWp) versus never smoked.Material and methodsSelf-reported smoking status and plasma ferritin lev�els were obtained from 849 boys (n = 470) and girls (n = 379) in the 7th–10th grade (age range = 13–17 years).ResultsThe ANCOVA revealed a main effect for gender (p < 0.000) and smoking status (p < 0.02) without an interaction effect (p > 0.9). Post-hoc analysis showed greater plasma ferritin in the adolescents smoking Wp (p < 0.03) and CgWp (p < 0.004) versus never smoked. Gender-stratified ANCOVA showed a main effect for smoking status in the boys (p < 0.02) and girls (p < 0.03). Additional comparisons among the boys showed greater plasma ferritin in the Wp (p < 0.006) and CgWp (p < 0.008) smoking groups versus never smoking, without differences (p > 0.5) between Wp and CgWp smoking. Another subgroup comparison showed greater plasma ferritin in the girls smoking Cg (p < 0.02) and CgWp (p < 0.02) versus never smoking, without a difference (p > 0.3) between Cg and CgWp smoking.ConclusionsThe results indicate that ferritin is elevated in adolescent smokers, particularly the boys smoking Wp and CgWp and in the girls smoking Cg and CgWp.

Control Accuracy

This study examined simultaneously the effects of distance of projection (4-, 6-, and 8-horizontal ft.) and object size (6-, 8.5-in., and 10-in. diameter balls) on object reception by children in the first grade. 6 boys and 6 girls were randomly assigned to each of the 3 distances (36 subjects total). Each subject was administered 36 trials, 12 attempted catches with each ball size at their assigned distance. All balls were projected by a device designed to control accuracy as well as the angle of projection for projections to each distance. Each attempted catch was evaluated by a 5-point scale ( r = .96). Trials, sex, distance of projection, ball size, and related interactions were examined using a conventional analysis of variance. Ball size was the only significant main effect, but the interaction between ball size and sex was also significant. Post hoc analysis indicated that the 10-in. ball gave significantly more catching success than the 8.5- or the 6-in. ball. Although more success in catching was achieved with the larger ball sizes, no difference in catching was attributable to the varying distances. The sequences for catching success according to ball size at each distance were not significantly different.

Main Effects

A single-solution anagram task was administered to high and low test-anxious 32 male and 32 female undergraduates under conditions of high and low external distraction. No significant main effects were found linking solution times to either test-anxiety level or the presence or absence of distracting stimuli. Following a planned post hoc analysis which assigned the anagrams into ‘hard’ or ‘easy’ categories, a significant main effect for level of test anxiety was found for the ‘hard’ anagrams, indicating that test anxiety debilitates performance only when the criterion task is especially difficult. Difficulty of anagrams also significantly interacted with subjects' sex, test anxiety, and distraction. The results are discussed in terms of the hypotheses that distracting stimuli may produce increases in arousal during difficult tasks and that these increments may either compromise or improve performance, depending upon the level of test anxiety which is viewed as a determinant of the initial arousal level of the subject.

The purpose of this study was to evaluate the validity and reliability of a tire pressure sensor (TPS) cycling power meter against a gold standard (SRM) during indoor cycling. Twelve recreationally active participants completed eight trials of 90 s of cycling at different pedaling and gearing combinations on an indoor hybrid roller. Power output (PO) was simultaneously calculated via TPS and SRM. The analysis compared the paired 1 s PO and 1 min average PO per trial between devices. Agreement was assessed by correlation, linear regression, inferential statistics, effect size, and Bland–Altman LoA. Reliability was assessed by ICC and CV comparison. TPS showed near-perfect correlation with SRM in 1 s (rs = 0.97, p < 0.001) and 1-min data (rs = 0.99, p < 0.001). Differences in paired 1 s data were statistically significant (p = 0.04), but of a trivial magnitude (d = 0.05). There was no significant main effect for device (F(1,9) = 0.05, p = 0.83, ηp2 = 0.97) in 1 min data and no statistical differences between devices by trial in post hoc analysis (p < 0.01–0.98; d < 0.01–0.93). Bias and LoA were −0.21 ± 16.77 W for the 1 min data. Mean TPS bias ranged from 3.37% to 7.81% of the measured SRM mean PO per trial. Linear regression SEE was 7.55 W for 1 min TPS prediction of SRM. ICC3,1 across trials was 0.96. No statistical difference (p = 0.09–0.11) in TPS CV (3.6–5.0%) and SRM CV (4.3–4.7%). The TPS is a valid and reliable power meter for estimating average indoor PO for time periods equal to or greater than 1 min and may have acceptable sensitivity to detect changes under less stringent criteria (±5%).

BACKGROUND: Hip pain is a common complaint in athletes of all ages. Hip pathology includes both intra- and peri-articular pain generators. Ultrasound (US) evaluation and guided injections are used in the clinical setting for diagnostic and therapeutic purposes. However, evidence regarding the impact of US-guided injections on quality of life (QoL) health outcomes in patients with hip pain and injury is understudied. PURPOSE: To examine the long-term efficacy of US-guided injections on QoL outcomes in patients presenting to a tertiary level academic hip preservation program. METHODS: Prospective longitudinal study design was used to evaluate 12-55 years old patients with hip pain/pathology. Patients completed a Hip Disability and Osteoarthritis Outcome Score (HOOS) questionnaire at the initial evaluation, 1.5-months, 4.5-months, and 12-months. Main outcome measures included change in QoL HOOS scores. Repeated measures analysis of variance (ANOVA) was performed to compare patients who received US-guided injections and patients who did not receive US-guided injections over time. Bonferroni pairwise comparison was performed as a post-hoc analysis. RESULTS: A total of 175 patients were included with a mean age of 24.1±9.8 years. There were 104 patients who received US-guided injections while 71 patients did not have US-guided injections. An interaction between US-guided injections over 12-months on QoL scores was identified. QoL increase over time was 6.5 points in patients without US-guided injection compared to 10.0 points in patients who had an US-guided injection ( P=0.040, Figure 1). Main effect of US-guided injections on QoL was not detected ( P=0.276). However, main effect of time on QoL was found ( P=0.003). Bonferroni post-hoc analysis indicated differences between initial evaluation and 1.5 months ( P=0.004, Figure 2), and initial evaluation and 12-months ( P=0.002, Figure 3). CONCLUSION: US-guided injections appeared to improve quality of life outcomes over the 12-month study period. US-guided injections may serve to help patients with hip pain presenting to clinic over time and promote and support non-surgical treatment regimes.

Abstract University students were screened using items from the Psychopathic Personality Inventory and divided into high (n = 13) and low (n = 11) Psychopathic Personality Trait (PPT) groups. The P300 component of the event-related potential (ERP) was recorded as each group completed a two-block autobiographical oddball task, responding honestly during the first (Phone) block, in which oddball items were participants' home phone numbers, and then feigning amnesia in response to approximately 50% of items in the second (Birthday) block in which oddball items were participants' birthdates. Bootstrapping of peak-to-peak amplitudes correctly identified 100% of low PPT and 92% of high PPT participants as having intact recognition. Both groups demonstrated malingering-related P300 amplitude reduction. For the first time, P300 amplitude and topography differences were observed between honest and deceptive responses to Birthday items. No main between-group P300 effects resulted. Post-hoc analysis revealed between-group differences in a frontally located post-P300 component. Honest responses were associated with late frontal amplitudes larger than deceptive responses at frontal sites in the low PPT group only.
