ABSTRACT Acute renal failure due to cast nephropathy (CAN) is a severe complication of multiple myeloma (MM). Here, we aimed to identify parameters associated with renal outcomes and survival in newly diagnosed MM patients with CAN‐related acute renal failure and to validate the IMWG criteria for renal response. CAN diagnosis was based on biopsy or clinical assessment. Of 787 registered patients, 354 met the inclusion criteria, requiring at least two therapy cycles with documented chemotherapy response, renal response, and eGFR. Baseline free light chain (FLC) levels (median 6825.65 mg/L) decreased below 500 mg/L in 67.8% of patients. According to IMWG classification, renal complete response, partial response, and minimal response were achieved in 33.9%, 19.5%, and 28.0% of patients, respectively. The best eGFR values > 60 mL/min/1.73 m 2 were observed in 33.9% of patients, while 33.3%, 22.3%, and 10.5% had best eGFR values of 30–59, 15–29, and < 15 mL/min/1.73 m 2 , respectively. Renal response correlated with baseline FLC levels, IgG kappa, eGFR, and ECOG status in multivariate analysis, as well as with myeloma response and FLC reduction in univariate analysis. Median overall survival was 77.6 months. Survival correlated with age, myeloma response, ECOG status, FLC kappa type, baseline eGFR, standard‐risk cytogenetics, and calcium levels, among other factors. A comparison of IMWG renal response criteria with classification based solely on best eGFR showed similar utility. Of 136 patients requiring dialysis, 80 (58.8%) were able to discontinue dialysis during therapy. Bortezomib containing myeloma therapy, along with significant FLC reduction, was associated with favorable outcome.

Iatrogenic displacement of third molars is a rare but significant complication of dental extractions, particularly in children where unique anatomic and developmental factors pose additional challenges. This report describes the case of a 12-year-old female who presented with a displaced maxillary third molar crown into the left maxillary sinus following dental extraction. This displacement resulted in acute orbital cellulitis, which was initially managed with oral antibiotic therapy. Endoscopic endonasal retrieval of the foreign body 4 months later was recommended after the initial infection was treated to reduce the risk of recurrent orbital and/or sinonasal infections. Surgical planning incorporated intraoperative navigation with existing cone beam computed tomography to minimize radiation exposure. The procedure was successful with no perioperative complications. This case highlights the importance of prompt recognition, careful surgical planning, and utilization of minimally invasive approaches to optimize outcomes while minimizing craniofacial morbidity in pediatric patients.

ABSTRACT Purpose Abnormal restrictions at myofascial interfaces are a key factor in chronic low back pain (CLBP) with myofascial pain syndrome (MPS), but no established imaging method exists for quantitative assessment. This pilot study evaluated the clinical feasibility of MR elastography (MRE)‐based slip interface imaging (SII) for visualizing myofascial mobility in CLBP‐MPS patients versus age−/sex‐/BMI‐matched healthy participants. A new SII biomarker, maximal normalized displacement discontinuity (), was introduced, and the previously developed normalized octahedral shear strain (NOSS) map was used for comparison. Preliminary assessments of vibration‐frequency effects, repeatability, and group differences in inter‐muscular mobility were conducted. Methods MRE was conducted at 30, 60, and 90 Hz to compare with NOSS for visualizing inter‐muscular slip interfaces at the quadratus lumborum‐erector spinae (QL‐ES) and erector spinae‐multifidus (ES‐M) muscle boundaries at L3‐L4. Repeatability of and NOSS was assessed at 30 Hz (identified as the best‐performing frequency) using within‐subject coefficients of variation and a linear mixed‐effects model from within‐ and between‐day scans. Clinical feasibility was then assessed via Wilcoxon rank‐sum tests in six CLBP‐MPS patients and matched controls. Results at 30 Hz exhibited superior delineation of slip interfaces compared to higher frequencies and NOSS. demonstrated significantly lower variation and better repeatability than NOSS. Healthy participants showed continuous, well‐defined slip interfaces, whereas CLBP‐MPS patients displayed disrupted interfaces with significant mobility reduction at L4 ES‐M. Conclusion SII with lower vibration frequency and map enhances visualization of lower back myofascial mobility and shows potential for assessing differences between healthy individuals and CLBP‐MPS patients.

The increasing adoption of plant-based diets (PBDs) has raised questions regarding their adequacy in supporting muscular strength and performance, particularly given concerns around the amino acid profile and bioavailability of plant proteins. This review synthesises current meta-analytical and clinical trial evidence to address the "plant protein paradox," which posits that plant proteins are inferior for maintaining muscle mass and strength. Recent high-quality data reveal no significant differences in muscular strength or athletic performance outcomes between plant-based and omnivorous diets when total protein intake and quality are optimised. Mechanistic studies demonstrate comparable muscle protein synthesis rates across protein sources, with soy and certain mixed plant proteins showing anabolic potential equivalent to animal proteins. Clinical recommendations emphasise attention to protein quantity, quality, leucine content, and micronutrient sufficiency to maximise muscle health on PBDs. Specific populations—including older adults and athletes—can safely adopt plant-based nutrition without compromising strength or functional performance. This evidence supports a shift beyond traditional, protein hierarchy models, positioning plant-based diets as a viable strategy for musculoskeletal health alongside their cardiovascular and environmental benefits.

Introduction Social media platforms, particularly X (formerly Twitter), play an influential role in professional networking and information dissemination. This study aimed to examine X usage trends among faculty in a single department of surgery at a large academic institution. Methods Faculty X accounts were analyzed from January to June 2022. Metrics such as follower count, number of accounts followed, and post (formerly: tweets) types (original/quoted reposts) were studied. Themes of posts were categorized as personal, promotional, educational, or related to academic events/conferences. Associations between faculty rank, division, gender, and post metrics were explored using Mann-Whitney U and Kruskal-Wallis tests. Results Of 133 faculty members, 53 (39.85%) had X accounts, with 3 excluded due to privacy settings. A total of 3476 posts were analyzed, averaging 0-34 posts/month per faculty. Categories included professional (63%, n = 2174), educational (19%, n = 653), and personal (13%, n = 436). No significant associations were found between faculty gender/division and posting rates. However, faculty rank correlated significantly with primary post categories ( P < 0.01). Associate professors, and professors posted more about academic events (2% and 1%) than instructors or assistant professors (1%). The most followed faculty actively promoted colleagues’ work through reposting. Conclusion Less than half the faculty in a single department of surgery engaged with X. Those active predominantly used it for promotion, followed by education and personal use. Adoption remains limited, highlighting opportunities for growth in utilizing X for academic dissemination.

Introduction Problematic alcohol use negatively impacts individuals, families and communities. While perceptions regarding alcohol use are likely vital to mitigating problematic alcohol use at the population level, little is known. Perceptions that demarcate normative versus problematic use may be relevant for interventions in communities with normative alcohol use. Our study explores ethnocentric perceptions of alcohol use in a community where alcohol use is historically integrated into its social fabric. Methods Mixed-methods study design using a culturally curated online survey with closed and open-ended responses assessed perceptions regarding alcohol use. Participants were members of the Kodava community: an affluent ethno-linguistic community in Southern India with an international presence. For Kodavas, alcohol consumption is normative and socially sanctioned. We studied perceptions of alcohol use among family members, including factors influencing its use and the impact of problematic alcohol drinking on immediate and extended family in three domains: health, finances and relationships. Results Of 711 total respondents, a small minority of 11.4% (n=81) stated that at least one immediate family member experienced negative impacts of alcohol use. Among respondents who reported on their extended family (n=639), 52.1% (n=333) endorsed at least one member experienced negative impacts. The integration of quantitative and qualitative data elucidates negative impacts of alcohol use within and at the intersections of health, relationships and finances. Conclusions First study to employ social media (WhatsApp) to survey a globally dispersed ethnic community on alcohol use impacts among family members. Interventions tailored to these perceptions, in culturally embedded communities, may improve outcomes. The framework and approach of this study can be replicated globally.
