Abstract The proliferation of advanced endoscopic resection techniques has provided a minimally invasive alternative to esophagectomy and revolutionized outcomes for patients with early-stage esophageal adenocarcinoma (EAC). This paradigm shift and the resulting research data on clinical and histologic determinants of treatment outcome have highlighted the heterogeneity of outcomes within EAC staged as T1 by invasion depth. Multidisciplinary cancer care teams are now routinely facing difficult decisions regarding the management of high-risk T1 EAC to balance the risk of long-term lymph node (LNM) or distant metastasis against the risks of surgical resection. In this review, we summarize the current state of knowledge regarding the staging and risk stratification of T1 EAC, with particular attention to features that contribute to a higher risk of LNM and cancer mortality. We review recent clinical trial data on positioning the use of endoscopic resection (cap-assisted or submucosal dissection) versus surgical resection in high-risk T1 EAC patients and describe adjunctive techniques to further improve risk stratification and treatment. Finally, we explore emerging and future directions, such as artificial intelligence and advanced biomarker analysis to further aid decision-making and enhance patient outcomes.

Introduction: Young-onset esophageal adenocarcinoma (EAC) often presents at advanced stages and is associated with poor outcomes. We aimed to examine the epidemiology of young-onset Barrett’s esophagus (BE) using the TriNetX database. Methods: Young-onset BE patients (age 18 to younger than 50 y) with esophagogastroduodenoscopy (EGD) within 1 year before index BE diagnosis between 2014 and 2023 were included. Negative binomial regression was used to evaluate incident-time trends, and logistic regression to assess for independent predictors of young-onset BE. Results: BE diagnosis was present in 76,691 (3.3%) of 2,337,786 patients that underwent EGD, of which 14,120 (18%) had prevalent young-onset BE. BE dysplasia/EAC was present in 6% of young-onset patients at initial diagnosis. Conventional BE risk factors also predicted young-onset BE: GERD (OR=2.4), White race (OR=2.4), male sex (OR=2.2), smoking (OR=1.2), and obesity (OR=1.1). Each additional risk factor increased the probability of BE prevalence by 74% in young patients versus 54% in older patients. The prevalence of young-onset BE was 4.5% with GERD and ≥3 additional risk factors, and 2.3% when ≥3 risk factors were present. Discussion: Young-onset BE accounts for 18% of all BE cases, demonstrates a striking 6% rate of dysplasia/neoplasia at initial diagnosis, and has a prevalence of 4.5% in those with GERD and ≥3 risk factors. These findings suggest that young-onset BE is an important patient population that merits further study. Additional studies are necessary to study the cost-effectiveness of BE screening in younger patients with multiple risk factors.

Study Design. Subanalysis of a prospective, multicenter, observational study at 72 US adult, pediatric, and mixed trauma centers. Objective. We investigated trauma-related risk factors and patient-level factors associated with multiregional spinal column injury, defined as cervical spine injury (CSI) requiring treatment and thoracolumbar injury (TLI). Summary of Background Data. Traumatic spinal injury causes morbidity and mortality in pediatric patients. Injuries to multiple spinal column regions require early identification and thoughtful management. Methods. All children <18 years undergoing cervical spine evaluation after blunt multisystem trauma were prospectively identified and enrolled. Clinically significant CSI was defined by cervical spine surgery or halo placement. TLI incidence and management was recorded. The primary outcome was multiregional spinal column injury (CSI+TLI). Results. Of 19,651 enrolled patients, 1484 children (7.5%) experienced a TLI, 159 (0.81%) had CSI requiring treatment, and 30 (0.15%) had CSI+TLI. Multivariate analysis revealed that the trauma-related factors mechanism of injury ( P <0.001), rib fractures (odds ratio (OR) 2.8 [2.3-3.4]), hemothorax/pneumothorax (OR 2.0 [1.7-2.4]), bowel injury (OR 4.0 [2.9-5.4]), pelvic fracture (OR 1.5 [1.2-1.9]), and clinically significant CSI (OR 1.9 [1.2-2.9]) were independently associated with TLI. Of the 159 children with clinically significant CSI, 30 also experienced TLI (19%). Multivariate analysis identified prehospitalization intubation (OR 3.1 [1.1-8.4]) and rib fractures (OR 3.9 [1.2-12.8]) as independent associations with CSI+TLI. Conclusions. Of children with CSI requiring treatment, 19% experienced TLI. MOI and various trauma-related injuries were independently associated with TLI, whereas prehospitalization intubation and rib fractures were independent risk factors for CSI+TLI. These factors should trigger screening for multiregional spinal column injury in pediatric trauma patients. Furthermore, if there is known TLI, the cervical spine should be evaluated, and if there is significant CSI, then dedicated imaging of the thoracic and lumbar spine is indicated. Level of Evidence.

Management of unstable upper lumbar fractures with corpectomy and posterior fixation is technically demanding, and conventional workflows may require intraoperative repositioning, increasing operative complexity. Lateral mini-open upper lumbar corpectomy (LMULC) paired with robotic-assisted (RA) posterior percutaneous pedicle screw fixation (PPPSF) can be performed in a single position to facilitate ventral spinal decompression and stabilization in the anatomically constrained upper lumbar spine. In this study, we describe the operative technique and report four illustrative cases of unstable L1 or L2 fractures treated with single-position LMULC, RA-PPPSF, and short-segment fusion. Clinical, radiological, intraoperative variables and postoperative outcomes were evaluated. The mean age was 52.3 ± 17.7 years. The median operation time was 314 min (range 268–361 min); the median estimated blood loss (EBL) was 225 mL (range 100–400 mL). The median preoperative kyphosis was 10.15° (range 8.4–14.6°), the median postoperative kyphosis measured 6.65° (range 1.7–10.8°) and the median correction achieved was 3.5° (range −2.4–12.9°). The median visual analog scale (VAS) pain score reduced from 7 (range 7–9) preoperatively to 4.5 (range 2–6) postoperatively at discharge. At a median follow-up of 12 months (range 6–15 months), all patients had uncomplicated recoveries, demonstrated solid fusion on imaging, and reported favorable MacNab outcomes. Single-position LMULC with RA-PPPSF was technically feasible in this preliminary illustrative series and resulted in favorable clinical and radiographic outcomes. However, further studies in larger cohorts are warranted to help confirm these findings and better define the potential advantages and limitations of this technique.

Abstract Hereditary hemorrhagic telangiectasia (HHT), an autosomal dominant vasculopathy affecting 1 in 5000 individuals, is the second most common inherited bleeding disorder worldwide. Despite this prevalence, comprehensive data on disease manifestations and complications remain limited. To address this gap, the US Congress allocated funding leading to the Comprehensive HHT Outcomes Registry of the United States (CHORUS), a prospective, 15-center longitudinal registry enrolling unselected patients with confirmed HHT. In this initial report, we describe findings from the first 600 participants, with a median age of 53 (range, 0-88) years and 60% female. Despite most participants developing typical HHT manifestations by age 13 years, the majority (63%) were not diagnosed until mid-to-late adulthood. Recurrent spontaneous epistaxis occurred in 95% of participants, chronic gastrointestinal bleeding in 30%, and heavy menstrual bleeding in 35% of postmenarche females, together resulting in moderate-to-severe mucosal bleeding in 76%. Iron deficiency and/or anemia were diagnosed in 68%, with 41% requiring IV iron and 25% requiring red cell transfusions. Serious complications of solid-organ arteriovenous malformations were frequent, including intracranial hemorrhage (3%), pulmonary hemorrhage (2%), venous thromboembolism (7%), arterial thromboembolism (11%), heart failure (7%), and pulmonary hypertension (7%). These data from CHORUS, the first national US registry of its kind, provide reliable, real-world estimates of the incidence, prevalence, and severity of numerous HHT manifestations and complications. HHT has a high burden of moderate-to-severe bleeding, anemia, thrombosis, and major neurologic and cardiopulmonary complications. There is a mean interval between first symptoms and diagnosis of &gt;2 decades, during which substantial, serious, and preventable HHT morbidity, including early intracranial hemorrhage, may occur. This trial was registered at clinicaltrials.gov as NCT06259292.

Background: Femoroacetabular impingement (FAI) is a common injury experienced by basketball players. Surgical management with arthroscopic labral repair and femoral osteochondroplasty can lead to successful outcomes for athletes whose nonoperative management fails. Recent studies have demonstrated that athletes undergoing hip arthroscopy in the setting of FAI had favorable return-to-sport (RTS) and sport continuation outcomes. Purpose: To evaluate patient-reported outcome measures (PROMs) and RTS rates at minimum 5-year follow-up in basketball players after hip arthroscopy for FAI. Study Design: Case series; Level of evidence, 4. Methods: All active basketball players at the recreational, high school, and collegiate levels who underwent primary hip arthroscopy with labral repair for FAI between August 2009 and December 2019 were identified. Postoperative RTS, revision rates, and surgery satisfaction at final follow-up were evaluated. PROMs were also analyzed as follows: visual analog scale, Tegner Activity Scale, modified Harris Hip Score, Hip Outcome Score–Activities of Daily Living, and Hip Outcome Score–Sport. Results: Fifty-three patients (64 hips) were included with a mean ± SD age of 21.2 ± 6.0 years. Most athletes played recreational or high school basketball (85%), while 15% played college basketball. Forty-three patients attempted to return to basketball. Of these patients, 35 (81%) returned to basketball after surgery, with 32 (91%) returning to the same level of play. Patients who returned to basketball had significantly improved outcomes on the modified Harris Hip Score ( P = .006), Hip Outcome Score–Activities of Daily Living ( P = .007), Hip Outcome Score–Sport ( P = .004), Tegner Activity Scale ( P = .010), and visual analog scale with use ( P = .041) as compared with those who did not return. High school athletes had decreased odds of RTS when compared with recreational athletes ( P = .01). There was significant improvement in all PROMs from baseline to minimum 5-year follow-up ( P < .05). Conclusion: At minimum 5-year follow-up, basketball players demonstrated durable improvements in PROMs and an RTS rate of 81% after hip arthroscopy for FAI. The majority of athletes returned to the same level of competition. There were significantly improved PROMs in patients who returned to sport versus those who did not. High school athletes had decreased odds of RTS when compared with recreational athletes. However, body mass index, sex, age, alpha angle, and basketball position did not significantly correlate with RTS outcomes.

ABSTRACT Objectives Systematic evidence reviews (SERs) produced by the U.S. Agency for Healthcare Research and Quality (AHRQ) Evidence‐based Practice Center (EPC) Program use contextual questions to provide context and background information on the topic. There is currently no standardized approach to address contextual questions in systematic reviews. This study explored the use of publicly available large language models (LLMs) in addressing contextual questions. Study Design Using a set of 20 published and 5 yet to be published SERs, we selected one contextual question per report and used it as a prompt to elicit answers from an LLM (ChatGPT, Bard, Claude, or Perplexity). Two independent reviewers rated the results using a priori established evaluation criteria ( https://osf.io/4k3cu/ ), comparing the response in the SER to LLM‐generated responses. The study was guided by six research questions addressing feasibility, validity of content, validity of structure, mistakes, congruence between responses, and incremental validity of using LLMs to address contextual questions. Results Using minimal prompt engineering produced relevant responses and documented the feasibility of LLM‐generated answers to contextual questions. Responses differed in content and format and are not reproducible (e.g., LLMs update regularly), but LLMs were able to produce articulate, clinically plausible, and well‐structured responses. We detected few factual errors, contradictions, and no instance of suspected bias, but citations supporting LLM‐generated responses could often not be produced or could not be verified (‘confabulations’). Congruence with human generated responses varied, with LLM‐generated responses providing more background on the topic and SERs providing more nuanced answers in response to the contextual question. Results regarding incremental validity were mixed and may depend on the tool. Conclusion LLMs are potentially helpful in addressing contextual questions in systematic reviews but human expertise remains essential for using the generated information in a meaningful way.

Abstract Hereditary hemorrhagic telangiectasia (HHT) results in recurrent severe epistaxis, chronic gastrointestinal bleeding, and other morbid manifestations. Pomalidomide was recently demonstrated to be efficacious for bleeding in HHT in the landmark PATH-HHT trial. Given that the vascular remodeling that results in bleeding improvement may require several months, characteristics associated with treatment response would be invaluable to plan treatment. Using data from PATH-HHT (NCT03910244), we identified characteristics associated with change from baseline in Epistaxis Severity Score (ESS; a well-validated 10-point HHT bleeding scale and the trial’s primary end point) using multivariable-adjusted repeated-measures models. Characteristics associated with a better response to pomalidomide at weeks 16 to 24 of the trial included a higher (more severe) baseline ESS (change from baseline, −0.76 [95% confidence interval (CI), −0.99 to −0.54] points per 1-point higher baseline score, P&lt; .001) and concomitant antifibrinolytic therapy (−0.73 [95% CI, −1.48 to 0.01] vs no therapy, P = .05). Characteristics associated with a less robust response were older age (0.29 [95% CI, 0.05-0.53] per 10 years older, P = .02) and underlying ACVRL1 germ line mutation (0.62 [95% CI, −0.04 to 1.27] vs ENG, SMAD4, or mutation not known, P = .06]. Characteristics notably associated with placebo response (placebo effect) were patient-reported outcome measures, such that those experiencing more severe disease at baseline had less placebo effect. In conclusion, several baseline patient and disease characteristics were associated with pomalidomide response, findings that may help guide patient selection for the use of pomalidomide in HHT. This trial was registered at www.Clinicaltrials.gov as NCT03910244.

INTRODUCTION: Ongoing surveillance after successful endoscopic eradication therapy for Barrett's esophagus (BE)-related neoplasia is essential to detect and manage recurrence. Despite established surveillance interval recommendations after complete eradication of intestinal metaplasia (CE-IM), patient compliance with repeat endoscopy is frequently suboptimal. Understanding patient drivers to adherence is essential to inform interventions that address the high rates of overdue surveillance and loss to follow-up. METHODS: Patients with BE-related neoplasia who achieved CE-IM were eligible for inclusion and classified as delayed or on-time for endoscopic surveillance. Patients were prospectively enrolled and participated in structured virtual interviews designed to explore barriers and facilitators to on-time care. A rapid qualitative analysis approach was applied, continuing until thematic saturation was reached. RESULTS: Thirty-nine patients were interviewed: 22 (56.4%) were delayed, and 17 (43.6%) were on-time for surveillance. Patients in the delayed group had longer mean BE segment lengths and a higher prevalence of tobacco use. Geographic distance from the treatment center was the most frequently cited barrier to follow-up (n = 17; 43.5%). Other common barriers were access limitations, financial concerns, misunderstanding of disease course, and test-related anxiety. DISCUSSION: Patient-related drivers of delay in postendoscopic eradication therapy surveillance are largely logistical, socioeconomical, and psychological in nature. Solutions to reduce the significant burden on the patient and achieve timely surveillance may include transitioning patients back to their local endoscopists after CE-IM or incorporating nonendoscopic surveillance methods through patient centered approaches.

Hypertension has been traditionally known to be highlighted by mean blood pressure; however, emerging evidence exhibits that blood pressure variability (BPV), including short-term, day-to-day, and visit-to-visit fluctuations can have an implication across multiple body systems. Elevated BPV reflects repetitive hemodynamic stress, affecting the physiologic hemostasis contributing to vascular injury and end organ damage. This narrative review is a compilation of recent evidence on the prognostic value of BPV, explained by pathophysiology, various devices with its measurement approaches, and, essentially, the clinical implication of BPV and the use of such devices utilizing artificial intelligence. A comprehensive literature search across PubMed, Cochrane Library, Scopus, and Web of Science were conducted, focusing on observational studies, cohorts, randomized trials, and meta-analyses. Higher BPV has been associated with an increased risk of cardiovascular mortality, stroke, coronary events, and heart failure, the progression of chronic kidney disease, cognitive decline, and preeclampsia, among other end organ damage, despite mean blood pressure. The various pathophysiologic mechanisms include autonomic dysregulation, arterial stiffness, endothelial dysfunction, circadian rhythm alteration, and systemic inflammation, which result in vascular remodeling and multisystem damage. Antihypertensive medications such as calcium channel blockers and renin–angiotensin–aldosterone system inhibitors seem to reduce BPV; randomized trials have not specifically investigated their BPV-reducing effects. The aim of this review is to highlight that BPV is a dynamic marker of multisystem risk, and question how various AI-based devices can aid continuous BPV monitoring and patient specific risk stratification.
