BACKGROUND Safe return to play (RTP) after anterior cruciate ligament (ACL) reconstruction is critical to patient satisfaction. Enhanced rehabilitation after ACL reconstruction with appropriate objective criteria for RTP may reduce the risk of subsequent injury. The cost-effectiveness of an enhanced RTP (eRTP) strategy relative to standard post-ACL reconstruction rehabilitation has not been investigated. MK0683 PURPOSE To determine if an eRTP strategy after ACL reconstruction is cost-effective compared with standard rehabilitation. STUDY DESIGN Economic and decision analysis. METHODS A decision-analysis model was utilized to compare standard rehabilitation with an eRTP strategy, which includes additional neuromuscular retraining, advanced testing, and follow-up physician visits. Cost-effectiveness was evaluated from a payer perspective. Costs of surgical procedures and rehabilitation protocols, risks of graft rupture and contralateral ACL injury, risk reductions as a result of the eRTP strategy, and relevant health utilities were derived from the literature. An incremental cost-effectiveness ratio of 13.8%. CONCLUSION The eRTP strategy in this study adds additional neuromuscular retraining and additional physician follow-up-as well as advanced testing goals upon which RTP is contingent-to traditional physical therapy. Our data suggest that these additions are cost-effective, even assuming only modest associated decreases in ACL graft failure. This study also determined that the only variable that had the potential to change the cost-effectiveness conclusion based on predetermined ranges was the additional cost of rehabilitation based on 1-way sensitivity analysis. CLINICAL RELEVANCE This study provides evidence of cost-effectiveness for payers, supporting the use of enhanced RTP programs. The sensitivity analyses herein may be used to determine if any given RTP program going forward is cost-effective, regardless of the exact components of the program.In an effort to achieve high sensitivity analysis methods for ultra-trace levels of heavy metals, numerous new nanomaterials are explored for the application in preconcentration processes and sensing systems. Nanomaterial-based methods have proven to be effective for selective analysis and speciation of heavy metals in combination with spectrometric techniques. This review outlined the different types of nanomaterials applied in the field of heavy metal analysis, and concentrated on the latest developments in various new materials. In particular, the functionalization of traditional materials and the exploitation of bio-functional materials could increase the specificity to target metals. The hybridization of multiple materials could improve material properties, to build novel sensor system or achieve detection-removal integration. Finally, we discussed the future perspectives of nanomaterials in the heavy metal preconcentration and sensor design, as well as their respective advantages and challenges. Despite impressive progress and widespread attention, the development of new nanomaterials and nanotechnology is still hampered by numerous challenges, particularly in the specificity to the target and the anti-interference performance in complex matrices.BACKGROUND Time to return-to-sport (RTS) after acute adductor injuries varies among athletes, yet we know little about which factors determine this variance. PURPOSE To investigate the association between initial clinical and imaging examination findings and time to RTS in male athletes with acute adductor injuries. STUDY DESIGN Cohort study (Prognosis); Level of evidence, 2. METHODS Male adult athletes with an acute adductor injury were included within 7 days of injury. Standardized patient history and clinical and magnetic resonance imaging (MRI) examinations were conducted for all athletes. Athletes performed a supervised standardized criteria-based exercise treatment program. Three RTS milestones were defined (1) clinically pain-free, (2) completed controlled sports training, and (3) first full team training. Univariate and multiple regression analyses were performed to determine the association between the specific candidate variables of the initial examinations and the RTS milestones. RESULTS We includegs, even extensive clinical and MRI examination does not assist considerably in providing a more precise estimate of time to RTS.RATIONALE Pulmonary rehabilitation following hospitalizations for exacerbations of chronic obstructive pulmonary disease (COPD) improves exercise capacity and health-related quality of life, and reduces readmissions. However, post-hospitalization pulmonary rehabilitation uptake is low. To date, no trials of interventions to increase uptake have been conducted. OBJECTIVE Effect of a co-designed education video as an adjunct to usual care on post-hospitalization pulmonary rehabilitation uptake. METHODS An assessor- and statistician-blinded randomized controlled trial with nested qualitative interviews of participants in the intervention group. Participants hospitalized with COPD exacerbations were assigned 11 to receive either usual care (COPD discharge bundle including pulmonary rehabilitation information leaflet) or usual care plus the co-designed education video delivered via a handheld tablet device at discharge. Randomization used minimization to balance age, sex, forced expiratory volume in 1 second (FEV1) % predicted, frailty, transport availability and previous pulmonary rehabilitation experience. MEASUREMENTS AND MAIN RESULTS The primary outcome was pulmonary rehabilitation uptake within 28 days of hospital discharge. 200 patients were recruited with 196 randomized (51% female, median (interquartile range) FEV1 % predicted 36(27, 48)). Pulmonary rehabilitation uptake was 41% and 34% in the usual care and intervention groups respectively (p=0.37), with no differences in secondary (pulmonary rehabilitation referral and completion) or safety (readmissions and death) endpoints. Six of the fifteen participants interviewed could not recall receiving the video. CONCLUSION A co-designed education video delivered at hospital discharge did not improve post-hospitalization pulmonary rehabilitation uptake, referral or completion.
