Background: Influenza-associated encephalopathy, encephalitis, and acute necrotizing encephalopathy (ANE) are rare but potentially life-threatening neurological complications of influenza. Adult cases remain poorly characterized because the available literature is largely limited to isolated case reports and small case series. Methods: A PRISMA-guided scoping review of the MEDLINE database was conducted through 31 May 2026. Published adult cases of influenza-associated encephalopathy, encephalitis, and ANE were identified and analyzed for demographic characteristics, clinical presentation, neuroimaging findings, treatment, and outcomes. Results: Eighty-three adult cases reported between 1958 and 2026 were included. The mean age was 45.6 ± 17.8 years, and 57.8% were male. Two-thirds did not have any underlying comorbidities. Neurological symptoms developed a mean of 4.6 days after influenza onset, with influenza A accounting for 80.7% of infections. Fever (91.6%), altered mental status (86.7%), and seizures (36.1%) were the most common manifestations. Encephalitis was the predominant presentation (44.5%), followed by encephalopathy (31.3%) and ANE (24.1%). MRI most frequently demonstrated cerebral hemispheric lesions (53.0%) and bilateral thalamic involvement (36.4%), while EEG abnormalities were reported in 69.6% of patients. Overall mortality was 22.9%, highest among patients with ANE (45.0%). Among survivors, 28.9% experienced persistent neurological sequelae. Conclusions: Influenza-associated encephalopathy, encephalitis, and ANE are rare in adults but are associated with substantial morbidity and mortality. This review represents the largest adult cohort reported to date and provides important insights into the clinical spectrum, neurodiagnostic findings, and outcomes of these uncommon complications. This review highlights significant gaps in knowledge and the need for collaborative multicenter studies to improve the diagnosis, treatment, and outcome of these severe complications of influenza infection.

Background: By 2030, nearly one-quarter of the U.S. population will be over age 65, emphasizing the need to understand factors that promote healthy aging. Vitality is often reduced to physical indicators in clinical frameworks, overlooking its multidimensional nature. Methods: This qualitative descriptive study explored how independently living older adults define and experience vitality, focusing on physical, emotional, cognitive, and social dimensions. Guided by Self-Determination Theory, semi-structured interviews were conducted with 10 participants aged 61–83 years purposively recruited from community and faith-based settings in Northeast Florida. Results: Thematic analysis revealed four interconnected themes: (1) Make Adjustments, Keep Going; (2) Being Mentally Jubilant; (3) Bonds that Keep Me Going; and (4) Thriving Amid Uncertainty. Conclusions: Findings suggest that participants perceived vitality as a dynamic, multidimensional process shaped by adaptation, purpose, and connection rather than physical health alone. These insights underscore the need for holistic approaches to vitality assessment and interventions that support autonomy, competence, and relatedness in later life.

Abstract Aims Randomized trials comparing percutaneous left atrial appendage occlusion (LAAO) with oral anticoagulation (OAC) for stroke prevention in patients with atrial fibrillation have yielded conflicting results across device generations and anticoagulant eras. This Bayesian meta-analysis of randomized trials aimed to compare LAAO vs. OAC for stroke or systemic embolism (SSE) and non-procedural clinically relevant bleeding (CRB). Methods and results We conducted a systematic search across five databases (PubMed, Embase, Scopus, Web of Science, and Cochrane CENTRAL) to identify randomized trials of LAAO vs. OAC. Primary outcomes of stroke or systemic embolism, non-procedural CRB and clinical benefit composite were estimated using a Bayesian hierarchical random effects model and findings confirmed across robust sensitivity and subgroup analyses. Posterior probabilities for superiority, non-inferiority and equivalence were estimated using clinically meaningful margins. Six randomized trials including 7004 participants in the intention-to-treat groups, were analysed. LAAO was not associated with lower SSE vs. OAC (pooled RR, 1.11; 95% CrI, 0.80–1.49), with a 74.6% posterior probability of favouring OAC. The posterior probability of crossing non-inferiority was P(HR < 1.4) of 89%. In contrast, LAAO reduced non-procedural CRB (pooled RR, 0.59; 95% CrI, 0.45–0.78). The net clinical benefit composite, pooling contemporary trials, demonstrated a pooled RR of 0.90 (95% CrI 0.51–1.50), with P(RR < 1) of 76%, with substantial heterogeneity for this outcome. Conclusion This Bayesian meta-analysis found no clear evidence supporting clinically meaningful non-inferiority of LAAO over OAC for stroke prevention. Despite reduced non-procedural bleeding, LAAO did not demonstrate a similar reduction in major bleeding.

ABSTRACT Reliable assessment of infarct severity is essential in experimental stroke research, yet commonly used approaches such as 2,3,5‐triphenyltetrazolium chloride (TTC) staining and magnetic resonance imaging require additional tissue processing, specialized equipment, or substantial time and cost. In this study, we developed and validated a rapid visual Infarct Score to determine infarct volume and evaluate neuroprotective efficacy in rat middle cerebral artery occlusion (MCAO) models. A retrospective analysis was performed using data from 315 male Sprague–Dawley rats, including TTC‐derived infarct volume, visual Infarct Score, neurological deficit scores, and body weight changes. The Infarct Score demonstrated the strongest correlation with infarct volume among individual indicators in both nontreatment (Rho = 0.71) and treatment cohorts (Rho = 0.68). We further developed a Comprehensive Score by integrating the Infarct Score with the Longa 5‐point score at 48 h, which showed the highest overall correlation with infarct volume (Rho = 0.75 in both cohorts) and strong discrimination of infarct severity (AUC = 0.90). Interrater reliability analysis demonstrated excellent agreement among independent raters (intraclass correlation coefficient = 0.89; Kendall's W = 0.83, both p < 0.001). Neuroprotective interventions, including therapeutic hypothermia, nitroglycerin, and remote ischemic conditioning combined with physical exercise, significantly reduced infarct volume, Infarct Score, Comprehensive Score, neurological deficits, and weight loss. These findings indicate that the Infarct Score offers a rapid, practical, and cost‐effective method for infarct assessment, whereas the Comprehensive Score further improves the predictive accuracy and may serve as a useful tool for evaluating stroke severity and treatment outcomes in preclinical studies.

Abstract Complement-mediated thrombotic microangiopathy can be difficult to recognize when it presents in the setting of an apparent clinical trigger, such as pregnancy, severe hypertension, or kidney transplantation. These conditions can each cause endothelial injury directly but may also unmask complement dysregulation in susceptible individuals. In these situations, the critical question is not whether a trigger exists but whether it fully explains the syndrome and whether urgent complement blockade is warranted to prevent irreversible kidney injury. In this How I Treat article, we use 3 real-world cases to illustrate how we approach this decision in practice. We emphasize the bedside features that most influence our threshold to treat, including the pattern and severity of kidney injury, tempo of disease progression, and lack of improvement with supportive or trigger-directed care. We also address the interpretation of complement genetic findings, pregnancy- and transplant-specific risk stratification, and the individualization of treatment duration. Functional assays can support mechanistic assessment in selected cases but remain an adjunct to diagnosis and should not drive management decisions.

Solitary plasmacytomas (SPs) are rare localized tumors of clonal plasma cells, either in the bone (solitary bone plasmacytoma) or in soft tissue/extraosseous (extramedullary) with either no or with minimal bone marrow (BM) infiltration (<10% clonal plasma cells by immunohistochemistry) and no evidence of systemic involvement or myeloma defining events. Approximately 50% of SPs will progress to symptomatic myeloma within 5 years after initial definitive local radiotherapy. Increased availability of improved diagnostic and monitoring tools has increased the sensitivity of detection of additional lesions and marrow involvement and has implications for the follow-up strategy after treatment. Thus, the definitions and requirements for the diagnosis and follow-up of SPs are evolving. The diagnosis of SP requires the careful exclusion of multiple myeloma (MM) that would require systemic therapy, by using all the available methods to detect systemic disease (advanced imaging, sensitive BM assessment methods, blood and urine tests). Local radiotherapy remains the mainstay of therapy, and despite the availability of innovative drugs for MM, the clinical benefit of systemic therapy currently remains poorly defined. The International Myeloma Working Group provides here updated recommendations for the diagnosis, evaluation, treatment, and response assessment of patients with SPs, incorporating recent data and advances in diagnostic tools.

PURPOSE Adherence to operative standards and thorough documentation of surgical technique are critical, particularly in multidisciplinary clinical trials. We sought to evaluate variability in the performance and documentation of oncologically relevant aspects of technical surgery among patients enrolled in Alliance A021501, a phase 2 National Clinical Trials Network randomized clinical trial of neoadjuvant therapy for borderline resectable pancreatic adenocarcinoma. METHODS We reviewed the primary operative and pathology reports of all enrolled patients who underwent complete pancreatic resection. Operative techniques and pathologic end points with potential to influence recurrence and survival were evaluated. RESULTS Fifty-one of 126 study participants (40.5%) underwent complete pancreatectomy. The extent of lymphadenectomy was documented in 36 (70.6%) operative reports, and 5 (9.8%) reports outlined the specific lymph node stations removed. Periadventitial dissection of the superior mesenteric artery was described in 25 of 50 (50.0%) operative reports. Immediate histopathologic analysis of the hepatic duct and pancreatic parenchyma margins was documented in 29 of 50 (58.0%) and 32 of 49 (65.3%) reports, respectively, and presence or absence of residual disease following resection was documented in 9 of 51 (17.6%) reports. Specimen orientation was documented in 19 of 51 (37.3%) pathology reports, and 30 of 49 (61.2%) pathology reports stated the distance between the tumor and final SMA margin. CONCLUSION Even in this rigorously controlled, multicenter, randomized pancreatic cancer clinical trial, performance of key elements of technical surgery was inconsistent, and documentation was incomplete. Standardization of technique and documentation in clinical trials and within clinical practice should be addressed to improve quality assurance and trial interpretability.

Purpose: This study aimed to evaluate how speech signal compression algorithms affect the acoustic and perceptual characteristics of dysarthric speech. As telepractice becomes more common in speech-language pathology, particularly in the assessment of dysarthria, understanding the impact of telecommunication compression on speech fidelity is essential for clinical decision making. Method: Speech samples were collected from 15 individuals with dysarthria, recorded locally and simultaneously via Zoom (Version 6.2.11). The Opus codec was used to process the locally recorded speech samples under fullband, wideband, and narrowband compression conditions. Acoustic measures were derived for all samples. Twenty experienced speech-language pathologists (SLPs) rated vocal quality and nasality for sustained vowels and rated articulatory precision and orthographically transcribed sentences across each condition. Results: Narrowband compression was associated with significantly degraded voice quality measures (e.g., harmonic-to-noise ratio, shimmer) and reduced transcription accuracy. Despite these changes in acoustics and intelligibility, ratings of articulatory precision, nasality, and vocal quality remained stable across conditions, suggesting SLPs could adjust for compression artifacts when making perceptual judgments. Conclusions: Speech compression, particularly in low-bandwidth (i.e., narrow) condition, impacts acoustic fidelity and intelligibility, though expert listeners maintain reliable perceptual judgments. These findings underscore the need to consider compression effects in telepractice and highlight the importance of developing optimized protocols for remote dysarthria assessment.
