The adoption of batteries across diverse applications requires electrode materials with a wider range of performance metrics, such as cost, safety, and material availability. Along the path to discovering new commercially viable materials, a fundamental understanding of chemical and atomic structure features that provide structural stability and effective ion transport is essential. In support of new understanding, we report the cycling behavior of metastable R-Nb2O5. R-Nb2O5 adopts an 'idealized' V2O5 structure, in which [NbO6] octahedra alternate in edge- and corner-sharing resulting in ReO3-like slabs, whereas Wadsley–Roth materials have ReO3-like blocks, linked through edge-sharing octahedra at intersecting crystallographic shear planes. We find that this slab structure is stable during cycling, with minor atomic structure changes and cycling curves that are symmetric on discharge and charge, resembling the behavior of Wadsley–Roth materials more than other related materials, such as ReO3, V2O5, or Nb3O7F. Based on our findings, R-Nb2O5 can serve as a 'structural bridge' between Wadsley–Roth block structures and V2O5, through which we can relate inter- and intra-polyhedral structures to cycling behavior and structural stability during cycling.

Introduction: A Canadian sports chiropractic research agenda has yet to be defined. The Delphi method can be utilized to achieve this purpose; however, the sample of experts who participate can influence the results. To better inform sample selection for future research agenda development, we set out to determine if differences in opinions about research priorities exist between chiropractors who have their sports specialty designation and those who do not. Methods: Fifteen sports clinical practice chiropractors who have their sports fellowship designation and fifteen without, were interviewed with a set of standardized questions about sports chiropractic research priorities. A centering resonance analysis and cluster analysis were conducted on the interview responses. Results: The two practitioner groups differed in their opinions about the type of research that they would like to see conducted, the research that would impact their clinical practice the most, and where they believed research was lacking. However, both groups were similar in their opinions about research collaborations. Conclusion: Sports clinical practice chiropractors, with their sports specialty designation and those without, differed in their opinions about sports chiropractic research priorities; however, they had similar opinions about research collaborations. These results suggest that it may be important to sample from both practitioner groups in future studies aimed at developing research agendas for chiropractic research in sport.

Omohyoid muscle syndrome is a rare cause of an X-shaped bulging lateral neck mass that occurs on swallowing. This is a diagnostic case report of a 22-year-old mixed martial arts athlete who acquired this condition. [ABSTRACT FROM AUTHOR]

Background: Stress fractures are troublesome injuries. Sites of occurrence are activity-related and specific anatomical sites are endemic to certain sports. Little is known about stress fracture patterns in golf. Objective: A structured review of the literature was conducted to identify the occurrence and injury sites of golf-related stress fractures. Methods: A literature search of MEDLINE, CINAHL, and SPORTDiscus was conducted using a combination of controlled vocabulary and truncated text words to capture all articles relevant to golf-related stress fractures. Articles meeting inclusion criteria were descriptively analyzed. Results: The search resulted in 164 articles, of which 13 met the inclusion, and reported 44 cases of golfrelated stress fractures. Seven anatomical injury sites were identified with rib stress fracture being the most commonly reported. Stress fractures occurred on the golfer's lead-side in 80% of cases. Conclusion: Golf-related stress fractures are infrequent injuries. The ribs were the most common stress fracture site, and a predilection for lead-side involvement was reported.

Objective: To present the clinical management and comprehensive differential diagnosis of a patient with anorectal pain from a perianal abscess., Clinical Features: A 41-year-old woman presented with pain localized to her perianal and gluteal region, accompanied by internal and external rectal pain. Prior to presentation, the patient had received a working diagnosis of levator ani syndrome., Intervention and Outcome: An interdisciplinary management approach was utilized. Diagnostic imaging confirmed the clinical suspicion of a perianal abscess and the patient underwent surgical drainage., Summary: Anorectal pain is complex and multifactorial and a diagnosis such as an abscess should not be overlooked. This case emphasized that practitioners must be diligent in their evaluation and management of patients with anorectal pain, including recognizing situations that require further imaging and interdisciplinary management., Competing Interests: The authors have no competing interests to declare.
