ABSTRACT Background: Successful use of nurse practitioner (NP) and physician assistant (PA) care models is vital to delivering optimal patient care, maintaining financial stability, and reducing staff burnout and turnover. Local Problem: A large cardiovascular surgery practice experienced substantial growth, leading to an obsolete NP and PA care model. Consequently, workplace satisfaction scores were reduced, and the NP and PA turnover rate in 2018 was unacceptably high. Methods: A multidisciplinary redesign team was formed to address gaps in the care model through a quality-improvement initiative. The team analyzed current workflows, collected external and internal survey data, conducted patient tracers, and observed staff. Seventeen collaborative care models were proposed by frontline staff members and presented to their peers for feedback. This feedback was used to select the best aspects of the proposed models to create a new model. Interventions: The updated care model consisted of several key changes, which included reducing NP- and PA-to-patient ratios, eliminating redundant tasks, shifting from location-based to surgical team–based coverage, ensuring top-of-scope practice, developing specialty service lines, and separating inpatient and outpatient practices. Results: After implementation of the new care model, NP and PA turnover rates decreased from baseline by an average of approximately 74% per year. Departmental work culture scores concomitantly increased from 68% to 85% after implementation of the new care model. Conclusions: Adapting care models in conjunction with departmental growth is crucial to enhancing staff satisfaction and reducing burnout.

Case: Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disorder characterized by progressive heterotopic ossification. Scoliosis may develop and progress rapidly, especially during adolescence. We report 4 patients with FOP and scoliosis during early adolescence: A 12-year-old girl underwent T4-S2 posterior spinal fusion (PSF); another 12-year-old girl underwent T4-S2 PSF; a 13-year-old boy underwent T3-L4 PSF; and a 14-year-old girl was managed nonoperatively because the complex deformity and ankylosed shoulders could not be adequately balanced with surgery. Conclusion: In patients with FOP, surgical intervention can reduce thoracic deformity and improve pulmonary function but carries substantial risks, including heterotopic ossification.

GGGGCC (G 4 C 2 ) repeat expansion in C9ORF72 is the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Toxicity is thought to result from the accumulation of either repeat RNAs and/or dipeptide repeat proteins (DPRs) translated from repeat-containing transcripts through repeat-associated non-AUG (RAN) translation. To disentangle RNA from DPR toxicity, we mutated a CUG codon predominantly used to initiate DPR translation from all three reading frames. This mutation disrupted DPR synthesis while preserving the expression of repeat-containing RNAs. Despite the accumulation of RNA foci, behavioral deficits and pathological abnormalities, including p-TDP-43 inclusions, STING activation, motor neuron loss, neuroinflammation, and increased plasma neurofilament concentration, were alleviated in C9ORF72 mice. Base editing of the CUG codon also improved molecular phenotypes and survival in patient induced pluripotent stem cell–derived neurons, which highlights the potential of therapeutically targeting DPR production rather than repeat RNAs.

A comprehensive approach that combines imaging, histopathologic analysis, and patient counseling can be used to develop personalized fertility-sparing and fertility-preserving protocols that are safe and effective and respect patient autonomy in making decisions related to their future fertility.

Importance A greater proportion of older patients (age ≥65 years) are undergoing thyroidectomy amidst an aging population. Given the elusive results in the literature, clarifying whether older patients face different thyroidectomy safety profiles is crucial for optimizing risk assessment and patient counseling. Objective To evaluate the association between older age (age ≥65 years) and thyroidectomy safety by comparing endocrine-related complications, including recurrent laryngeal nerve injury, hypocalcemia, hematoma, and mortality in older compared with younger patients. Data Sources Ovid MEDLINE, CINAHL, Ovid Embase, and the Cochrane Library were systematically searched from inception to May 29, 2025; only English-language studies were included. Study Selection Cohort studies comparing thyroidectomy outcomes between older and younger patients and reporting endocrine-related complications were included. Two independent reviewers screened abstracts and full texts. Of 3192 studies identified, 11 met inclusion criteria. Data Extraction and Synthesis Two independent reviewers extracted data following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Risk of bias across studies was evaluated using the ROBINS-I (Risk of Bias in Nonrandomized Studies of Interventions) tool. Random-effects models were used to pool data. Main Outcomes and Measures Incidence of recurrent laryngeal nerve injury, hypocalcemia, and hematoma; odds ratios (ORs) with 95% CIs were calculated. Results The analysis included 11 studies with a total of 427 886 patients of whom 104 232 (24.4%) were older adults (≥65 years). Older adults had greater odds of overall recurrent laryngeal nerve injury (2.3% vs 1.0%; OR, 1.58; 95% CI, 1.15-2.16; I 2 = 76%), hematoma (2.4% vs 1.0%; OR, 2.32; 95% CI, 1.70-3.16; I 2 = 0%), and mortality at last follow-up (0.3% vs 0.01%; OR, 11.09; 95% CI, 1.77-69.52; I 2 = 90%) compared with younger patients. However, rates of overall hypocalcemia (OR, 0.80; 95% CI, 0.61-1.05; I 2 = 71%) and wound complications (OR, 1.38; 95% CI, 0.92-2.06; I 2 = 0%) were similar. Conclusions and Relevance This systematic review and meta-analysis found that thyroidectomy is safe in older patients, with only small absolute increases in recurrent laryngeal nerve injury, hematoma, and mortality despite statistical significance. These findings support individualized counseling and perioperative planning while acknowledging the overall safety of thyroidectomy in this population.

OBJECTIVE Chordomas are rare, locally aggressive primary neoplasms. Resection with negative margins is the primary recommended therapeutic approach, while adjuvant radiotherapy and chemotherapy can also play a role in their treatment in certain situations, including lesions with positive margins or those that are poorly differentiated or dedifferentiated. Cervical spine chordomas pose significant surgical challenges given their proximity to critical anatomical structures and the mechanical constraints of the cervical spine. In the current case series, authors aimed to explore the clinical and patient-reported outcomes (PROs) of the surgical treatment of cervical chordomas in a large multicenter cohort. METHODS This multicenter case series analysis utilized data from the prospectively collected Primary Tumor Research and Outcomes Network (PTRON) registry, from its inception (May 16, 2016) to data extraction (February 29, 2024). The study population was restricted to patients with histologically confirmed cervical chordomas involving levels C0–7, who underwent surgical treatment at one of the participating centers, and for whom both the initially planned and postoperatively pathologically confirmed surgical margins were documented. Patient demographics, tumor characteristics, surgical and adjuvant treatments, local recurrence–free survival (LRFS), overall survival (OS), and perioperative adverse events were retrieved. PROs included the Spine Oncology Study Group Outcomes Questionnaire version 2.0 (SOSGOQ2.0), EQ-5D, and SF-36 version 2.0 (SF-36v2). RESULTS Thirty-eight patients were identified, 12 of whom underwent true en bloc resection (EBR), 18 of whom underwent deliberate intralesional resection, and 8 of whom underwent EBR after intralesional surgery or in whom EBR failed. True EBR led to better LRFS (92% vs 83% vs 63%, respectively) and OS (83% vs 39% vs 50%, respectively). Surgical adverse events within 1 year were more frequent with true EBR (100% vs 39% vs 75%, respectively). EQ-5D, SOSGOQ2.0, and SF-36v2 showed improvement with true EBR, whereas the trends for PROs from the other groups were more variable. CONCLUSIONS This multicenter case series analysis provides critical insights into the clinical outcomes and PROs in the largest cohort of surgically treated cervical spine chordomas described to date. It underscores the importance and challenges of wide resection for oncological control. It establishes the associated morbidity and provides an overview of PROs following surgery. These findings contribute valuable evidence to inform shared decision-making and optimize patient care.

Purpose: While acquired apraxia of speech (AOS) has been the focus of intervention research for decades, little information is reported about the demographic representation of study participants. This article examines the extent to which published AOS treatment studies report participants' age, sex/gender, race/ethnicity, language background, and socioeconomic status; identifies critical gaps in the literature; and considers implications for representativeness. This information supports the important call to capture these patient factors systematically and thereby advance equity in research and clinical care. Method: This study is part of a larger systematic review examining treatment outcomes for acquired AOS. A comprehensive search of databases from 1951 to April 2024 was completed to determine the proportion of treatment articles that reported demographic information related to diversity. Studies were reviewed by trained raters using a standardized data extraction protocol with a consensus protocol. Results: While participant age and sex/gender were reported in nearly all studies (99% and 100%, respectively), only 24% of studies reported on race/ethnicity, 15% provided information on participants' language background, and none reported socioeconomic status. Among studies that included race/ethnicity, 89% of the participants were White, with minimal representation of other racial/ethnic groups. Conclusions: The underreporting of race/ethnicity, language background, and socioeconomic factors limits the generalizability and ecological validity of AOS treatment research. The field must prioritize inclusive participant recruitment and consistent demographic reporting. We propose a practical template for use in both research and clinical contexts to support more thorough data collection and to inform future work in diagnosis, assessment, and intervention for AOS.

Abstract Background Effective fluid status monitoring in chronic heart failure (HF) patients is critical for preventing decompensation and hospitalization. Conventional methods, such as daily weight tracking, often fail to detect early, pre-symptomatic fluid retention. As fluid accumulation affects the vocal tract, subtle voice alterations can serve as a biomarker for congestion. In this work, we present preliminary results from the first 55 patients enrolled at the German Heart Center at Charité (DHZC) within the multicenter VAMP-HF study, assessing the performance of AI-driven voice analysis for non-invasive fluid status monitoring. Methods The study design incorporated a run-in period for the first 20 patients to refine the recording setup and ensure sufficient audio quality for subsequent data collection. An additional three patients were excluded due to clinical deterioration or in-hospital mortality. Participants provided daily voice recordings (sustained vowels, standardized text, and varying sentences) alongside clinical measurements such as NT-proBNP, daily weight, and left-ventricular ejection fraction. A speaker-independent XGBoost classifier was trained on acoustic features to classify patient states (admission, discharge, and intermediate states). Performance was evaluated using a nested leave-one-patient-out approach, ensuring strict training and validation data separation. Results The final analysis included 32 patients (mean age 76.12 ± 12.65 years). At admission, patients had a mean NT-proBNP of 9575.55 ± 8202.87 pg/mL and a mean weight loss of 4.2 ± 4.29 kg until discharge. The trained machine learning model achieved an F1-score of 0.75 (Fig. 1b), demonstrating its ability to distinguish between admission and discharge states, based solely on voice samples. An exemplary prediction for a test patient is shown in Fig. 1a. Notably, the model was also able to detect subtle vocal changes even in patients with <2 kg weight loss. Conclusion Our findings suggest that AI-driven voice analysis is a feasible biomarker for detecting heart failure decompensation. While not directly compared with conventional early warning thresholds, these results support the hypothesis that voice-based biomarkers may serve as an early indicator of fluid congestion. Further validation in larger cohorts is needed to confirm these findings and enable integration into remote HF monitoring programs.

Abstract Introduction Catheter ablation is a cornerstone treatment for atrial fibrillation (AF). However, AF recurrence after initial ablation remains a challenge, often requiring repeat ablation procedures. Purpose This meta-analysis evaluates the effectiveness of repeat catheter ablation for the management of recurrent atrial arrhythmia following an initial ablation, focusing on ablation techniques, anatomical targets, and pulmonary vein (PV) reconnection. Materials and Methods A systematic literature search of MEDLINE, Scopus, and the Cochrane Central Register of Controlled Trials (CENTRAL) was conducted on studies reporting outcomes of repeat and initial ablation procedures. Data on atrial arrhythmia recurrence, ablation technique, ablation target, and PV reconnection were extracted. A random-effects meta-analysis was performed using the ‘metaprop’ function to estimate the atrial arrhythmia recurrence rate after repeat ablation. Results A total of 53 studies (8,117 patients) were included. The pooled atrial arrhythmia recurrence rate after repeat ablation was 30% (95% CI: 27%–34%), with PV reconnection observed in 90% of cases following initial ablation. The lowest recurrence rate was observed with cryoballoon ablation (CBA) followed by radiofrequency ablation (RFA) at 23% (95% CI: 15%–33%, I² = 83%). Recurrence rates varied based on the ablation strategy, with RFA followed by CBA resulting in a 29% recurrence rate (95% CI: 19%–42%, I² = 83.7%), CBA used in both initial and repeat procedures at 30% (95% CI: 23%–37%, I² = 44.1%), and RFA performed for both ablations at 32% (95% CI: 26%–37%, I² = 80.2%). Patients who underwent repeat ablation with pulmonary vein isolation (PVI) alone had a recurrence rate of 25% (95% CI: 18%–35%, I² = 88.5%). In contrast, those who received PVI with additional ablation lines, excluding complex fractionated atrial electrograms (CFAE), had a higher recurrence rate of 31% (95% CI: 27%–34%, I² = 84.3%). The recurrence rate increased further to 38% (95% CI: 32%–46%, I² = 87.3%) when PVI was combined with CFAE and additional lines. PV reconnection rates varied by vein, with the left inferior pulmonary vein (LIPV) exhibiting the lowest rate at 23% (95% CI: 22%–24%, I² = 20.3%). The left superior pulmonary vein (LSPV) and right inferior pulmonary vein (RIPV) showed similar reconnection rates (26%), while the right superior pulmonary vein (RSPV) had a rate of 25% (I² = 0.0%). Conclusion Repeat ablation for atrial fibrillation carries a risk of atrial arrhythmia recurrence, largely driven by PV reconnection. Strategies involving CBA followed by RFA and PVI-based ablations demonstrated favourable outcomes. Lower reconnection rates in left-sided PVs, particularly the LIPV, highlight the need for optimised ablation techniques.

Abstract Background Normal weight obesity (NWO) has been linked to metabolic syndrome (MetS), cardiovascular disease (CVD) and mortality, but has not been comprehensively studied in the Hispanic population. Purpose Our study aims to examine the CVD risk factors associated with NWO and to compare the development of CVD risk factors between NWO and normal weight non-obese (NWNO) Hispanic adults over 6 years. Methods This is a prospective study using data from the Hispanic Community Health Study (HCHS). Interviews and clinical assessments were collected from 2008–2011 (visit 1) to 2014–2017 (visit 2). NWO was defined as a body mass index (BMI) between 18.5–24.9 kg/m2 and a body fat percentage of ≥25 % in men and ≥35% in women, estimated using the Tanita scale. We identified 1,000 HCHS participants as having a normal weight at visit 1 and not missing data on covariates of interest including hypertension (HTN), hyperlipidemia (HLD), MetS, and insulin resistance (Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) ≥2.5). Participants were categorized into NWO (n=104) or NWNO (n=896) groups. Univariate logistic regression models were used to estimate the odds ratio (OR) and 95% confidence intervals (CI) of the association between health risk factors and NWO. Multivariate logistic regression models were used to estimate the odds of developing CVD risk factors over 6 years, using propensity score matching. Results The prevalence of NWO among our sample of Hispanic adults was 10.4% and the 6-year incidence of NWO at visit 2 was 3.5% (n=31) from NWNO participants at visit 1. Higher BMI (OR=5.19; 95% CI=3.15–9.27, p<0.001) and a higher mean overnight heart rate (OR=1.34; 95% CI=1.01–1.79, p=0.043) were statistically significantly associated with NWO at visit 1. Furthermore, HTN (OR=2.88; 95% CI=1.31–6.71, p=0.011), HLD (OR=2.12; 95% CI=1.21–3.77, p=0.009), and MetS (OR=3.48; 95% CI=1.62–8.09, p=0.002) were statistically significantly associated with NWO at visit 1. Participants with NWO at visit 1 had higher odds of developing insulin resistance (OR=1.79; 95% CI=1.07–3.04, p=0.029) and MetS (OR=2.03; 95% CI=1.15–3.66, p=0.016) at visit 2 compared to NWNO participants at visit 1, after age and sex matching. Conclusion Among Hispanic adults, the prevalence of NWO was associated with a higher BMI, higher mean overnight heart rate, treated HTN, HLD, and MetS. Hispanic adults with NWO were more likely to develop insulin resistance and MetS over 6 years compared to NWNO Hispanic adults. Overall, NWO among Hispanic adults was associated with CVD risk factors which places this population at a higher risk for CVD morbidity and mortality.
