Abstract Background Dysphagia can lead to fatal aspiration pneumonia in progressive supranuclear palsy (PSP). Little is known about the longitudinal progression of dysphagia or whether it differs across PSP clinical variants. Objectives To characterize longitudinal changes in dysphagia across PSP variants and determine relationships with disease severity and rate of atrophy in PSP‐related regions. Methods Sixty‐one PSP patients were recruited and underwent at least two serial evaluations, comprising neurological and videofluorographic exams, and MRI. Variables‐of‐interest were the oral and pharyngeal total sum scores (OTSS/PTSS) from the Modified Barium Swallow Impairment Profile, the Penetration Aspiration Scale (PAS), Functional Oral Intake Scale (FOIS), and lingual pressure assessments. Rates of change were compared across PSP variants and related to baseline scores, PSP Rating Scale and regional brain atrophy rates. Results Dysphagia progressed longitudinally, particularly with worsening in OTSS and anterior and posterior lingual pressures. Rate of change in OTSS was fastest in PSP with predominant speech‐language disorder. Negative correlations were observed between rates of change and baseline scores for OTSS, PTSS and PAS. Rates of change in lingual pressure measures correlated with rates of change in the PSP Rating Scale. Rate of change in the FOIS correlated with rates of change in OTSS and lingual pressure. Rates of brain atrophy were associated with baseline OTSS, PTSS, and PAS. Conclusions Dysphagia and lingual pressure worsen over time in PSP, with variability in rates of change in the OTSS across PSP variants and evidence that dysphagia is related to rates of atrophy.

Abstract Introduction Combat casualty care requires standardized proficiency criteria to ensure readiness in austere environments, yet gaps persist in defining performance thresholds for critical trauma skills. The Combat Medical Skills Sustainment Consortium (CMSSC), a novel military-civilian collaboration, aimed to validate competency thresholds for 21 Department of Defense-identified trauma skills. Materials and Methods A prospective cohort study (2022-2025) enrolled 1,495 military and civilian personnel across five academic centers, stratified by experience (novice, intermediate, expert). Skills, including cricothyroidotomy, whole blood transfusion, and ultrasound-guided vascular access, were assessed using validated checklists in Role 2-congruent simulations. Statistical analysis compared checklist performance against participant experience with a priori checklist scores estimated at 40% (novices) and 90% (experts). Results Competency thresholds were established, ranging from 77% (mechanical ventilation) to 100% (handoff). Experts achieved 85%-98% proficiency across most skills, with novices at 34%-97%. A ceiling effect was observed for less complex skills consistent with the power law of practice. Conclusion The Combat Medical Skills Sustainment Consortium validated standardized assessment tools, with potential to address readiness gaps through military-civilian synergy. Findings support consortium-guided curriculum development and highlight the need for longitudinal skill decay studies. Impact This study sets a benchmark for trauma care skills assessment, facilitating rapid adoption across military and civilian settings.

Background and Aims: Liver transplantation has evolved from a treatment restricted to patients with end-stage liver disease to a therapeutic option for selected patients with primary and metastatic liver malignancies. This review explores the rapidly expanding field of transplant oncology, highlighting its role in hepatocellular carcinoma, colorectal liver metastasis, neuroendocrine liver metastasis, and intrahepatic and perihilar cholangiocarcinoma. Emphasis is placed on strategies to broaden eligibility, optimize donor organ use, and improve oncologic outcomes. Approach and Results: We synthesized current evidence from clinical series, registries, and experimental protocols to evaluate patient selection criteria, outcomes, and peri-transplant management. Key topics include downstaging approaches to meet transplant criteria, such as locoregional therapies and systemic regimens, and their prognostic implications. Advances in donor utilization have been analyzed for their capacity to expand the graft pool. In addition, the review addresses the integration of oncologic principles into immunosuppression regimens, balancing graft protection with cancer control. Collectively, the reported studies demonstrate improved survival and reduced recurrence when stringent selection and multimodal therapy were applied. Conclusions: Transplant oncology reshapes the therapeutic landscape of liver malignancies, with growing evidence supporting liver transplantation in carefully selected patients beyond traditional indications. Optimized downstaging, innovative donor strategies, and tailored immunosuppression are pivotal for safe expansion. Continued collaboration between the transplant and oncology disciplines, along with prospective trials, is essential to further define standardized protocols and solidify transplantation as a cornerstone of multidisciplinary cancer care.

Importance Total thyroidectomy is the established surgical standard for hereditary and sporadic medullary thyroid cancer (sMTC). However, for unilateral sporadic tumors, its benefit over lobectomy remains uncertain. Objective To compare oncologic outcomes between total thyroidectomy and lobectomy in patients with sMTC. Data Sources and Study Selection MEDLINE, Embase, Scopus, and Cochrane Central Register of Controlled Trials were searched from inception to December 2025 to identify comparative studies on patients with sMTC who underwent total thyroidectomy or lobectomy. Data Extraction and Synthesis Reviewers working independently and in duplicate screened titles, abstracts, and full-text articles for eligibility using standardized instructions. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses ( PRISMA ) and Meta-Analysis of Observational Studies in Epidemiology ( MOOSE ) guidelines were used for reporting. Main Outcomes and Measures Primary outcomes were mortality, overall survival, structural recurrence, biochemical cure, and distant metastasis development. The secondary outcome was postoperative complications. Effect measures were calculated as odds ratios (ORs) or relative risks (RRs) with 95% CIs using a random-effects model. The risk of bias was assessed using the Newcastle-Ottawa Scale. Results Nine retrospective studies met inclusion criteria and comprised 1371 patients (295 of 397 patients [74.3%] with documented sex were female, and median age ranged from 45.0 to 58.2 years). A total of 531 patients (38.7%) underwent lobectomy and 840 (61.3%) underwent total thyroidectomy. Of 341 tumors, 280 (82.1%) lacked extrathyroidal extension, 284 of 401 tumors (70.8%) measured smaller than 2 cm (70.8%), and 197 of 343 tumors (57.4%) were node negative; central neck dissection was performed in 445 of 492 patients (90.4%). Multifocal disease was uncommon and reported in 30 of 330 patients (9.1%). Mortality did not differ at 5 years (RR, 0.30; 95% CI, 0.07-1.35) or beyond (RR, 1.00; 95% CI, 0.40-2.47). Overall survival at 5 years was similar (RR, 1.02; 95% CI, 0.94-1.11). Total thyroidectomy was not associated with lower structural recurrence rates at 5 years (OR, 0.45; 95% CI, 0.14-1.49), but it was associated beyond 5 years (OR, 7.26; 95% CI, 1.07-49.21). No differences were observed for biochemical cure at 5 years (OR, 0.86; 95% CI, 0.47-1.56) or beyond 5 years (OR, 0.87; 95% CI, 0.26-2.89). Distant metastasis development did not differ at 5 years (OR, 1.64; 95% CI, 0.09-31.52). Sensitivity analyses revealed no differences across any outcomes. Postoperative complications were more common in total thyroidectomy. Risk of bias was high in 4 studies, moderate in 4, and low in 1. Conclusions and Relevance Findings in this systematic review and meta-analysis, based on data from retrospective studies, suggest that thyroid lobectomy may be associated with oncologic outcomes comparable to total thyroidectomy in selected patients with sMTC.
