Paper Tape Prevents Foot Blisters: A Randomized Prevention Trial Assessing Paper Tape in Endurance Distances II (Pre-TAPED II).

OBJECTIVE: To determine whether paper tape prevents foot blisters in multistage ultramarathon runners. DESIGN: Multisite prospective randomized trial. SETTING: The 2014 250-km (155-mile) 6-stage RacingThePlanet ultramarathons in Jordan, Gobi, Madagascar, and Atacama Deserts. PARTICIPANTS: One hundred twenty-eight participants were enrolled: 19 (15%) from the Jordan, 35 (27%) from Gobi, 21 (16%) from Madagascar, and 53 (41%) from the Atacama Desert. The mean age was 39.3 years (22-63) and body mass index was 24.2 kg/m (17.4-35.1), with 31 (22.5%) females. INTERVENTIONS: Paper tape was applied to a randomly selected foot before the race, either to participants' blister-prone areas or randomly selected location if there was no blister history, with untaped areas of the same foot used as the control. MAIN OUTCOME MEASURES: Development of a blister anywhere on the study foot. RESULTS: One hundred six (83%) participants developed 117 blisters, with treatment success in 98 (77%) runners. Paper tape reduced blisters by 40% (P < 0.01, 95% confidence interval, 28-52) with a number needed to treat of 1.31. Most of the study participants had 1 blister (78%), with most common locations on the toes (n = 58, 50%) and heel (n = 27, 23%), with 94 (80%) blisters occurring by the end of stage 2. Treatment success was associated with earlier stages [odds ratio (OR), 74.9, P < 0.01] and time spent running (OR, 0.66, P = 0.01). CONCLUSION: Paper tape was found to prevent both the incidence and frequency of foot blisters in runners.

Assessing teamwork in the trauma bay: introduction of a modified "NOTECHS" scale for trauma.

BACKGROUND: A modified nontechnical skills (NOTECHS) scale for trauma (T-NOTECHS) was developed to teach and assess teamwork skills of multidisciplinary trauma resuscitation teams. In this study, T-NOTECHS was evaluated for reliability and correlation with clinical performance. METHODS: Interrater reliability (intraclass correlation coefficient) and correlation with the speed and completeness of resuscitation tasks were assessed during simulation-based teamwork training and during actual trauma resuscitations. RESULTS: For T-NOTECHS ratings done in real time, intraclass correlation coefficients were .44 for simulated and .48 for actual resuscitations. Reliability was higher (intraclass correlation coefficient = .71) for video review of resuscitations. Better T-NOTECHS scores were correlated with better performance during simulations, evidenced by a greater number of completed resuscitation tasks (r = .50, P < .01) and faster time to completion (r = -.38, P < .05) In actual resuscitations, T-NOTECHS ratings improved after teamwork training (P < .001). Higher T-NOTECHS scores were correlated with better clinical performance, evidenced by faster resuscitation (r = -.13, P < .05) and fewer unreported resuscitation tasks (r = -.16, P < .05). CONCLUSIONS: Improvement in T-NOTECHS scores after teamwork training, and correlation with clinical parameters in simulated and actual trauma resuscitations, suggest its clinical relevance. Further evaluation, aiming to improve reliability, may be warranted.

Full-thickness supraspinatus tears are associated with more synovial inflammation and tissue degeneration than partial-thickness tears.

BACKGROUND: The objective of this study was to determine whether the tear size of a supraspinatus tendon correlated with synovial inflammation and tendon degeneration in patients who underwent shoulder arthroscopy for rotator cuff repair. We hypothesized that increased synovial inflammation would correlate with greater tear size of the supraspinatus tendon at the time of surgery. MATERIALS AND METHODS: Tissue from the synovium, bursa, torn supraspinatus tendon, and subscapularis tendon was obtained from patients during shoulder arthroscopy to evaluate the messenger RNA expression of proinflammatory cytokines, tissue remodeling, and angiogenesis factors in the tendon, bursa, and synovium. Additional tissue was fixed to determine histologic changes including inflammation, vascular ingrowth, and collagen organization. RESULTS: Increased expression of interleukin 1ß, interleukin 6, cyclooxygenase 2, matrix metalloproteinase (MMP) 9, and vascular endothelial growth factor was found in the synovium of patients with full-thickness tears versus partial-thickness tears (P < .05). In the supraspinatus tendon, increased expression of MMP-1, MMP-9, MMP-13, and vascular endothelial growth factor was found in the full-thickness group. The upregulation of these genes in the full-thickness group was consistent with enhanced synovial inflammation, greater vascular ingrowth, and the loss of collagen organization in both supraspinatus and subscapularis tendons as determined by histology. CONCLUSION: Increased synovial inflammation and tissue degeneration correlate with the tear size of the supraspinatus tendon. A better understanding of the relationship between synovial inflammation and the progression of tendon degeneration can help in the design of novel and effective treatments to limit the advancement of rotator cuff disease and to improve their clinical outcomes.
