A beverage containing protein (PRO) and carbohydrate (CHO) may have an ergogenic effect on endurance performance. However, evidence regarding its efficacy on similar conditions to athletes' race day is still lacking. The objective of this study was to compare the effects of 3 different nutritional supplementation strategies on performance and muscle recovery in a duathlon protocol. Thirteen male athletes (29.7 ± 7.7 years) participated in 3 simulated Olympic-distance duathlon trials (SDTs) under 3 different, randomly assigned supplementation regimens: CHO drink (75 g CHO), isocaloric CHO plus PRO drink (60.5 g CHO and 14.5 g PRO), and placebo drink (PLA). Supplements were offered during the cycling bout. Blood samples were collected before, immediately after, and 24 h after each SDT for creatine kinase (CK) analysis. Isometric peak torque (PT) was measured before and 24 h after each SDT. The primary outcome measure was the time to complete the 5-km running section (t) at a self-selected pace. There was no difference in t between CHO (1270.3 ± 130.5 s), CHO+PRO (1267.2 ± 138.9 s), and PLA (1275.4 ± 120 s); p = 0.87, effect size (ES) ≤ 0.1. Pre-post changes for PT and CK were not significant for any of the 3 conditions (PT: p = 0.24, ES ≤ 0.4; CK: p = 0.32, ES = 0.3-1.04). For endurance sports lasting up to 2 h, with a pre-exercise meal containing CHO at 1.5 g·kg, supplementation with CHO or CHO+PRO does not offer additional benefits for performance and muscle recovery when compared with PLA.

Paper mills represent one of science's greatest threats to the integrity of the entire scientific enterprise because they have become entrenched in a culture of the commercialization and corruption of science's assets, whether these be authorships, data sets, entire papers, editorial positions, or influence during editorial processes to favor a culture of unfair publication practices. This journal, which has taken proactive and exemplary steps to deal with this plague of fakery, is no stranger to the workings of such academic criminality, as exemplified by a string of retractions resulting from paper mill interference and association. This letter posits that a public database, and blacklist, of known paper mills is needed, as well as of authors who have a track record of using paper mills, but recognizes that the establishment of such a blacklist may pose practical, legal, and ethical challenges to its implementation and maintenance.

Department of Orthopaedic Surgery, Chungbuk National University Hospital, Cheongju, Republic of Korea.
Background: Autologous osteochondral transplantation (AOT) is an option to treat large osteochondral lesions of the talus (OLTs), accompanying subchondral cyst, and previous unsuccessful bone marrow stimulation (BMS) procedures. Although there is extensive literature on the outcomes of surgical interventions for medial osteochondral lesions, research focusing on lateral lesions remains limited. This article presents the intermediate-term clinical and radiologic outcomes following AOT for lateral OLTs.
