New solvent-free polymer electrolytes are proposed based on a linear perfluorinated copolymer synthesized by enzymatic methods. The system is biphasic and exhibits two distinct conductivity pathways for long-range Na + -cation migration.

Abstract Fibrodysplasia ossificans progressiva (FOP) is an ultra-rare genetic condition characterized by congenital malformations of the great toes and progressive heterotopic ossification (HO) in specific anatomic patterns. Present management summarized here is focused on early diagnosis, assiduous avoidance of injury and iatrogenic harm, symptomatic amelioration of painful flare-ups, and optimization of residual function. Twenty-one members of the International Clinical Council on FOP (ICC) and seven consultants from 15 countries, chosen for their clinical expertise in FOP, developed this summary statement. Further advances in therapeutics will be based on rigorous clinical trials to assess novel and emerging treatment and prevention strategies. A detailed and updated exploration of the topics outlined in this brief perspective can be found in “The Medical Management of Fibrodysplasia Ossificans Progressiva: Current Treatment Considerations” which can be found on the International Clinical Council on FOP (ICC) website (www.iccfop.org).

Abstract Frailty is highly prevalent in cardiovascular disease and associates with poor clinical outcomes. Several cardiovascular conditions benefit from invasive interventions, but the impact of these procedures in frail patients remains unclear. We thus performed a systematic review and meta-analysis to summarize evidence and quantify the pooled effect of clinical outcomes of invasive cardiovascular interventions among frail vs. non-frail patients. Systematic search of two electronic databases from January 2015 to April 2025 was performed including all randomized controlled trials (RCTs) and prospective cohort studies examining outcomes of invasive cardiovascular interventions stratified by frailty. Outcomes included all-cause mortality, hospitalizations, and other adverse outcomes. Risk ratios (RRs) and their 95% confidence intervals (CI) were assessed using random-effects models. Thirty-one studies (10 RCTs, 21 prospective, 3 retrospective studies) with a total of 27 534 participants were included. Compared with non-frail patients, frail patients after cardiovascular procedures were at higher risks of all-cause mortality (RR 3.14, 95% CI: 2.29-4.30), and hospitalizations (RR 1.88, 95% CI: 1.29-2.73). Frail patients undergoing transcatheter aortic-valve implantation and percutaneous mitral-valve interventions did not have significant increased mortality risks compared with non-frail patients (P > 0.05). Pre-frailty predicted lower mortality risks amongst patients undergoing transcatheter vs. surgical aortic valve replacement (HR 0.78, 95% CI: 0.67-0.92). Frail patients with non-ST elevation myocardial infarction derived similar mortality benefits from an invasive vs. conservative approach (HR 1.13, 95% CI: 0.64-2.01). In conclusion, frailty prognosticates adverse outcomes following invasive cardiovascular interventions and influences treatment efficacy, highlighting its significance in treatment selection

Background Catatonia in medically ill patients is rare but often unrecognized. This monograph summarizes current knowledge on the diagnosis, epidemiology, etiology, and management of catatonia occurring in the medical setting. Methods PubMed searches were used to identify relevant articles from 1962 to present. Results More than 3,000 articles were obtained and reviewed for relevance, including references of articles identified by the initial search. Several areas were identified as important, including: (1) catatonia and delirium; (2) malignant catatonia; (3) pediatric catatonia; (4) catatonia associated with another medical condition (CAMC); (5) drug exposure and withdrawal syndromes associated with catatonia; and (6) treatment of catatonia in the medical setting. Conclusions Catatonia in the medically ill appears to have numerous etiologies, although etiology does not seem to modify the general treatment approach of prompt administration of lorazepam. Delirium and catatonia are commonly comorbid in the medical setting and should not be viewed as mutually exclusive. Electroconvulsive therapy should be offered to patients who do not respond to benzodiazepines or have malignant features. Removing offending agents and treating the underlying medical condition is paramount when treating CAMC. Memantine or amantadine may be helpful adjunctive agents. There is not enough evidence to support the use of antipsychotics or stimulants in treating CAMC.

Background Anti- N -methyl-D-aspartate receptor (anti-NMDAR) encephalitis was formally described in 2007 and includes a range of psychiatric and neurologic symptoms. Most patients with anti-NMDAR encephalitis initially present to psychiatrists for diagnosis and treatment. However, there is limited literature summarizing treatment strategies for psychiatric symptoms. In an effort to improve identification and treatment, this review article provides an overview of anti-NMDAR encephalitis, with a focus on psychopharmacologic treatment strategies. Two case reports provide a clinical context for the literature review. Methods The authors conducted a PubMed search. Results Prominent psychiatric symptoms of anti-NMDAR encephalitis include psychosis, agitation, insomnia, and catatonia. Neuroleptics may be helpful for managing psychosis and agitation, but may exacerbate movement abnormalities. Diphenhydramine and benzodiazepines are helpful for agitation and insomnia. In addition, the anticholinergic affinity of diphenhydramine can improve dystonia or rigidity attributable to anti-NMDAR encephalitis, while benzodiazepines and electroconvulsive therapy have been used for catatonia associated with this condition. Conclusions Psychiatrists play an important role in the diagnosis and treatment of anti-NMDAR encephalitis. Recognizing the typical clinical progression and closely monitoring for accompanying neurologic symptoms will facilitate diagnosis and timely treatment. Careful selection of psycho-pharmacological interventions may reduce suffering.

Objective: To develop, implement, and evaluate a novel process used for residency application review that deemphasizes metrics known to create bias with the goal of interviewing and matching a more diverse resident cohort. Methods: Between 2020 and 2023, a novel standardized rubric and application review process were developed and implemented at the authors’ academic training program. The rubric deemphasized USMLE scores, honor society membership, and number of publications while utilizing an AI-driven pre-sort of applications, facilitating holistic review. This weighted applicant attributes identified in personal statements, life experiences, achievements in community, leadership roles, otolaryngology-specific impressions highlighted in letters of recommendation, and otolaryngology-specific research and publications similarly to academic metrics (clerkship grades and standardized test scores). Demographics of applicants interviewed and matched into our program were compared pre- and post-implementation using descriptive statistics. Results: Using a standardized rubric to review residency applications that deemphasizes traditional metrics, the authors’ otolaryngology residency program has interviewed, ranked, and matched more diverse candidates. As a result, from 2019 to 2022, the overall resident cohort has diversified from 4% historically marginalized residents to 24%, from 28% female residents to 44%, and from 33% of residents outside our geographic region to 66%. Conclusion: There is significant underrepresentation among otolaryngology residents. Selection based upon USMLE Step 1 scores, honor society membership, and number of publications have been shown to restrict diversity. Purposeful holistic review increases diversity in interviewed and matched resident cohort.

ABSTRACT Introduction Etripamil is a fast‐acting intranasally self‐administered calcium‐channel blocker developed for termination of paroxysmal supraventricular tachycardia (PSVT). Prior studies have demonstrated safety and efficacy of etripamil for PSVT termination following an initial medically supervised test dose during sinus rhythm. NODE‐303 is an open‐label, single‐arm study that evaluated etripamil for multiple, at‐home PSVT episodes, without test dose before first use. Methods Patients applied an ECG monitor at symptom onset and self‐administered etripamil (70 mg) if a vagal maneuver was unsuccessful. ECG monitoring occurred for ≥ 1 h following study drug administration. A repeat 70‐mg dose was introduced during the study for symptoms persisting 10 min after the first dose. Safety measures included treatment‐emergent adverse events (TEAEs) and ECG arrhythmia‐surveillance. Efficacy measures were captured for PSVT termination during treatment of each of the multiple episodes. Results 1054 perceived PSVT episodes were etripamil‐treated in 503 of 1116 patients enrolled. TEAEs within 24 h were mostly mild or moderate and localized: 30.2% of patients experienced nasal discomfort, nasal congestion (13.9%), rhinorrhea (13.1%), epistaxis (7.4%). TEAE frequencies decreased across multiple PSVT episodes and were similar for single versus repeat doses. For first PSVT episodes, 70.5% of patients converted to sinus rhythm by 60 min post etripamil (median time to conversion = 18.3 min [14.2–25.6]). Conversion in earlier episodes was consistently predictive of conversion in subsequent episodes. Conclusions Etripamil nasal spray self‐administered in a real‐world setting was well tolerated, effective, and had a consistent safety profile as a single‐ or repeat‐dose regimen across multiple PSVT episodes.

Abstract Meniscus allograft transplant (MAT) can provide meaningful improvement in patient outcomes in those who are otherwise meniscus deficient. A common finding in the setting of a failed MAT is meniscus extrusion. Meniscus centralization is a technique performed to reduce the meniscus to its intra‐articular location and has been shown to improve postoperative pain and function in patients with an extruded meniscus. Prior techniques have been described for meniscus centralization in the setting of a meniscus root tear or with the use of single tension devices that are tensioned after meniscocapsular fixation. We present a minimally invasive technique for meniscus centralization that can be performed in conjunction with MAT using a centralization stabilization suture and re‐tensionable root‐fixation subchondral anchors that can be secured prior to meniscocapsular fixation.

Abstract Jagim, AR, Horswill, CA, Dobbs, WC, Twohey, EE, Tinsley, GM, Fields, JB, and Jones, MT. Minimum wrestling weight for high school girls wrestling: Time to revisit minimal body fat percent. J Strength Cond Res 39(3): 332–339, 2025—The purpose of this study was to determine whether an alternative body fat percentage (BF%) could be established as a safer margin for minimal wrestling weight (MWW) determination by evaluating the distribution of BF% and MWW values naturally occurring for high school girls wrestling. Data from the 2022–2023 high school season were retrospectively analyzed. In total, 33,321 female wrestlers completed skinfold (SKF) assessments or bioelectrical impedance analysis (BIA) in accordance with sport governing body mandates for weight certification. Frequency statistics and descriptive analysis were performed to compute normative MWW and BF% profiles. Body fat percentage thresholds of 12% (12MWW) and the BF% value defining the lowest fifth percentile were used to determine the resulting MWW and minimum weight class for each method. The median ± interquartile range for BF% was 28.3 ± 9.2%. There was a difference ( p < 0.001) in BF% values between BIA (28.4 ± 6.8%) and SKF (29.4 ± 7.6%), but a trivial effect size (ES = 0.14). The fifth percentile for BF% was 19%, which was used for alternative MWW determination (19MWW). 12MWW and 19MWW were 11.2 ± 6.4 kg ( p < 0.001; ES = 1.8) and 8.6 ± 7.7 kg ( p < 0.001; ES = 1.1) lower than the body mass of the wrestlers at the time of weight certification. Nearly all BF% values were above the 12% threshold currently used to determine MWW. Current body weights were more than 9.1 kg above MWW values for both 12MWW and 19MWW. Increasing the minimum BF% threshold from 12 to 19% would affect a small percentage of wrestlers and improve the margin of safety for those intent on achieving a lower weight class.
