Background: Lung cancer remains the leading cause of cancer-related mortality globally, largely due to delayed diagnosis in its early stages. While conventional diagnostic tools like low-dose CT and tissue biopsy are routinely used, they suffer from limitations including invasiveness, radiation exposure, cost, and limited sensitivity for early-stage detection. Liquid biopsy, a minimally invasive alternative that captures circulating tumor-derived biomarkers such as ctDNA, cfRNA, and exosomes from body fluids, offers promising diagnostic potential—yet its sensitivity in early disease remains suboptimal. Recent advances in Artificial Intelligence (AI) and radiomics are poised to bridge this gap. Objective: This review aims to explore how AI, in combination with radiomics, enhances the diagnostic capabilities of liquid biopsy for early detection of lung cancer and facilitates personalized monitoring strategies. Content Overview: We begin by outlining the molecular heterogeneity of lung cancer, emphasizing the need for earlier, more accurate detection strategies. The discussion then transitions into liquid biopsy and its key analytes, followed by an in-depth overview of AI techniques—including machine learning (e.g., SVMs, Random Forest) and deep learning models (e.g., CNNs, RNNs, GANs)—that enable robust pattern recognition across multi-omics datasets. The role of radiomics, which quantitatively extracts spatial and morphological features from imaging modalities such as CT and PET, is explored in conjunction with AI to provide an integrative, multimodal approach. This convergence supports the broader vision of precision medicine by integrating omics data, imaging, and electronic health records. Discussion: The synergy between AI, liquid biopsy, and radiomics signifies a shift from traditional diagnostics toward dynamic, patient-specific decision-making. Radiomics contributes spatial information, while AI improves pattern detection and predictive modeling. Despite these advancements, challenges remain—including data standardization, limited annotated datasets, the interpretability of deep learning models, and ethical considerations. A push toward rigorous validation and multimodal AI frameworks is necessary to facilitate clinical adoption. Conclusion: The integration of AI with liquid biopsy and radiomics holds transformative potential for early lung cancer detection. This non-invasive, scalable, and individualized diagnostic paradigm could significantly reduce lung cancer mortality through timely and targeted interventions. As technology and regulatory pathways mature, collaborative research is crucial to standardize methodologies and translate this innovation into routine clinical practice.

Objectives: Historically, horizontal cleavage meniscus tears have been debrided with single leaflet preservation, but more recently this has been challenged by repair of these tear types. While circumferential meniscus repair with all-inside and inside-out instrumentation has been described, there remains a paucity of literature regarding the clinical outcomes of this technique. Our purpose was to assess clinical outcomes and reoperation rates of circumferential meniscus repair for horizontal cleavage tears at minimum 2-year follow-up. Methods: Patients with isolated horizontal cleavage tears of the meniscus (Fig. 1a) undergoing primary circumferential meniscus repair (Fig. 1b), including both inside-out and all-inside suturing techniques, at a single institution between 2015 and 2022 were eligible for inclusion and analyzed retrospectively. Arthroscopic images and operative notes were examined to confirm circumferential meniscal repair. Patient demographics, surgery details, and clinical findings were extracted from the institutional electronic medical records. Exclusion criteria consisted of patients not consenting for research, less than 2-years of clinical follow-up, and concurrent ipsilateral repair of a non-horizontal cleavage tear. Patients were not excluded if they had a concomitant anterior cruciate ligament reconstruction (ACLR). Thirty-seven patients met the criteria for inclusion in this study. Knees were analyzed for laterality, number of sutures, suturing technique, concurrent injuries, concurrent procedures, and surgical history. Visual Analogue Scale (VAS) for pain, Tegner, and International Knee Documentation Committee (IKDC) scores were collected at minimum 2-year follow-up and analyzed. Return to sport (RTS) and revision surgery were analyzed. Results: Thirty-seven patients (25 male, 12 female; mean age, 29.4 ± 12.4 years) who underwent circumferential meniscal repair of a horizontal cleavage tear were included in the study and followed for a mean of 6.2 years (range, 2.2-9.3 years, Table 1). There was a total of 38 knees (23 right, 15 left). One patient (3%) had bilateral circumferential meniscal repair surgeries done at separate times. Three (16%) patients failed primary repair and had secondary partial meniscectomy. Similar numbers of circumferential meniscal repairs were performed on lateral and medial menisci, 21 (55%) and 17 (45%), respectively. An average number of 3 ± 2 sutures were used at the time or repair with one of 38 menisci (3%) having a hybrid combination of both all-inside and inside-out suture technique, 24 menisci (63%) had all-inside technique, and 13 menisci (34%) had inside-out technique. Concurrent procedures included 4 ACL reconstructions (3 autograft, 1 allograft), and 8 chondroplasties (4 patella, 2 trochlea, 1 medial femoral condyle, and 1 unspecified, Table 2). At the time of final follow-up, patients reported mean Tegner activity scores of 6.2 ± 2.3, VAS pain with rest of 1.0 ± 2.0, VAS pain with use of 2.5 ± 2.7, and IKDC of 81.6 ± 18.6. When asked, using a VAS Five Point scale, how their knee is currently compared to before their surgery, 14 (74%) feel much better than before surgery, 2 (11%) feel slightly better than before surgery, 1 (5%) feels no change when compared to before their surgery, 2 (11%) feel slightly worse than before surgery, and no one felt much worse than before surgery. Sixteen patients were involved in sports before their surgery. Of those that played sports before their surgery, 14 (88%) returned to sport (Table 3). The most common sports played were hockey (19%), volleyball (19%), tennis (13%), and football (13%). Levels of sport played before surgery included 7 (44%) recreational, 6 (38%) high school, 2 (13%) college, and 1 (6%) club. Levels of sport played after surgery for those who returned to sport included 6 (43%) recreational, 2 (14%) high school, 5 (36%) college, and 1 (7%) club with a significant increase in levels of sport played after surgery ( p ≤ 0.006) compared to before surgery. Conclusions: At an average of 6-years of follow up, there was an 84% success rate of circumferential meniscal repair for horizontal cleavage tears. Most patients who play sports, return to sport and do so at the same or higher level and report successful PROMs. Circumferential meniscal repairs should be considered for patients with horizontal cleavage tears.

Purpose To compare clinical and functional outcomes (including range of motion, clinical laxity, reoperation/revision rates, and patient‐reported outcome measures) of combined anterior cruciate ligament/posterior cruciate ligament reconstruction (ACLR/PCLR) with and without suture tape (ST) augmentation via a propensity‐matched cohort analysis. Methods A retrospective review was performed to identify all patients who underwent simultaneous primary ACLR/PCLR between 2001 and 2022. A 1:1 propensity match was performed using patient sex, Schenck classification grade, age ±8 years, and body mass index ±10 to produce 2 cohorts: ACLR/PCLR with and without (control) ST augmentation. Clinical outcomes (visual analog scale [VAS], range of motion, Tegner activity scale, Lysholm score, and International Knee Documentation Committee subjective score) were analyzed. Results The propensity match produced a final cohort of 50 ACLR/PCLR patients: 25 with ST augmentation and 25 nonaugmented controls. Most patients had a KD3M injury (12 in each cohort), and no significant differences were noted in concomitant neurovascular, meniscal, or chondral injuries between the groups. Forty patients (80%) completed follow‐up at a mean of 4.7 years for the ST cohort and 8.5 years for the control cohort ( P > .05). Postoperative ST versus control values for outcome measures including VAS at rest (0.9 vs 1.5; P = .71), VAS with use (3.0 vs 2.2; P = .24), International Knee Documentation Committee (75.7 vs 76.3; P = .37), Lysholm (81.8 vs 77.6; P = .91), and Tegner activity (4.8 vs 5.4; P = .37) scores showed no differences ( P > .05 for all). There were no differences in excessive postoperative clinical laxity between ST and control cohorts (ST n = 1 vs control n = 2, Lachman 2+, P = .140; ST n = 3 vs control n = 1, posterior drawer 2+, P = .122). The total number of patients who underwent reoperation was 7 of 25 (28%) for the ST cohort and 8 of 25 (32%) for the control cohort ( P = .76). Conclusions Concomitant ACLR/PCLR utilizing ST augmentation showed similarly satisfactory postoperative clinical outcomes at a minimum 2‐year follow‐up compared to a matched cohort without ST. The use of an independent ST did not limit motion or increase the incidence of complications or revision surgery. Level of Evidence Level III, retrospective comparative case series.

The Dublin ISUP Consensus Conference covered the proceedings on the best practice recommendations on nonurachal glandular lesions of the urinary bladder, bladder diverticular cancers, and molecular features of bladder and urachal glandular lesions. The conference proceedings on urachal neoplasms (except for their molecular features) are published elsewhere. The rationale for convening this conference was the lack of structured and consented pathologic recommendations in these rare lesions. Consensus by participants was reached on the following statements: (1) intestinal metaplasia with dysplasia is considered to be a precursor to primary bladder adenocarcinoma; (2) dysplasia arising from cystitis glandularis should be reported in terms of focality (focal or nonfocal) and grade (low or high); (3) the term “adenocarcinoma” should only be used for carcinomas showing pure (nonurothelial) morphology and should not be used interchangeably in urothelial carcinoma with “glandular differentiation” because of the pathobiological differences and management implications; (4) the different histologic subtypes of bladder adenocarcinoma should be specified in the report; (5) immunohistochemistry has an ancillary role in the work up of bladder adenocarcinoma versus gastrointestinal or Müllerian-type adenocarcinomas; (6) lymphovascular invasion should be included as a parameter when reporting bladder adenocarcinoma; (7) representative or targeted sampling will be sufficient for bladder diverticulum resection specimens; and (8) molecular analysis in genomic profiling should be performed only in advanced or metastatic bladder and urachal adenocarcinomas for targetable therapy. This report on glandular (nonurachal) lesions of the bladder from the Dublin ISUP consensus conference will serve as a best practice recommendation and as a guide for future research on these relatively rare lesions.

Objectives Cervical spine (c-spine) X-ray (XR) remains an important tool for pediatric trauma patients. XR is a low radiation alternative to multidetector CT (MDCT). Our primary aims were to analyze the sensitivity of a negative c-spine XR and to analyze what factors lead to additional imaging after a negative c-spine XR. Methods A retrospective cohort study was conducted at a level 1 pediatric trauma center from 2012 to 2021. We compared the group with negative c-spine XR and no additional imaging to the group with negative c-spine XR followed by additional c-spine MDCT and/or MRI. Results There were 2,081 negative XRs and 1,974 (95%) had their c-spines cleared without additional imaging. No patient required an operation for a clinically significant c-spine injury in this group, and we consider this no missed injuries. The remaining 108 patients had additional c-spine imaging after negative c-spine XR for c-spine clearance (24 MDCT, 76 MRI, 8 MDCT and MRI). Indications for additional c-spine imaging were pain (48.1%), Glasgow Coma Scale (GCS) score ≤14 (43.5%), and paresthesia (8.3%). Patients who received additional imaging were more likely to have a GCS score ≤12 (25.4% vs 4.1%), Injury Severity Score >15 (21.9% vs 8.1%), Level 1 Trauma activation (21% vs 5%), Abbreviated Injury Scale head score of 4 or 5 (29% vs 5%), be intubated (30% vs 2%), and have non-accidental trauma as their mechanism of injury (20% vs 1%) (p value<0.0001, for all). Five patients who received additional imaging were treated with a cervical collar, but no operative intervention. Conclusions In this cohort, screening XR had a sensitivity of 100% for clinically significant c-spine injuries. GCS was the most significant predictor of obtaining additional imaging. A negative XR combined with a normal physical examination in an evaluable pediatric patient is a safe way of clearing the c-spine. Level of evidence Study contains level III evidence.

ABSTRACT Hereditary hemorrhagic telangiectasia (HHT, Osler‐Weber‐Rendu disease) is the second most common inherited bleeding disorder worldwide, affecting approximately 1 in 5000 people. Development of disease‐modifying and efficacious hemostatic agents to treat HHT has finally begun after decades without such medical therapies. However, the lack of consensus on standardized severity definitions, outcome criteria, and terminology remains a major obstacle to clinical investigation and therapeutic development in HHT. Additionally, with the ongoing repurposing of antiangiogenic agents and emerging development of novel HHT‐specific therapies, comparative clinical trials are expected in the future. Therefore, to end the problematic heterogeneity hindering these efforts, the Global Research and Medical Advisory Board (GRMAB) of the Cure HHT Foundation, an international group of recognized HHT experts, convened a conference of expert HHT clinician‐investigators from within GRMAB as well as invited external experts in HHT and bleeding disorders generally, patients with HHT, and patient advocates to define standard terminology and definitions for outcomes and severity classification for bleeding and anemia in HHT. These criteria and definitions should be adopted by regulators, investigators, and the pharmaceutical industry in the development and performance of interventional clinical trials and cohort studies to allow improved comparability between clinical trials, facilitate communication between clinicians and investigators, improve therapeutic guideline development, and provide a standardized framework for regulatory agencies. Search Strategy and Selection Criteria Evidence for this report was systematically identified and evaluated utilizing two search strategies in Ovid MEDLINE, described in full detail in the Appendix, pp.4–13. The searches were conducted on January 7, 2025. The titles and abstracts of each record were reviewed, and the inclusion criteria were applied to all search results to identify full text articles to be retrieved for further review. All retrieved full texts were then reviewed to reach a final determination if a study met the inclusion criteria. Included references were then compiled into evidence tables, which were then utilized by the International Consensus Report Working Group throughout the development of report recommendations.

In this brief review we discuss the potential reasons underlying and follow up of patients who have a positive non-endoscopic swallowable cell collection device+biomarker (such as TFF3) test but no evidence of Barrett’s esophagus on endoscopy. We discuss the potential role of careful examination of the gastroesophageal junction and targeted biopsies of any visible lesions, as well endoscopic follow up in 3-5 years in the absence of any alarm symptoms. Considerations of the use of new technologies such as wide area transepithelial sampling in this situation are also discussed.

BACKGROUND There is a scarcity of artificial intelligence models trained on frozen pathology. One way to expand the clinical utility of models trained on permanent pathology is by applying them to frozen sections and fine-tune based on weaknesses. OBJECTIVE To qualitatively evaluate a deep learning model trained on permanent pathology to classify squamous cell carcinoma on Mohs surgery frozen sections to learn model shortcomings and inform retraining and fine-tuning. MATERIALS AND METHODS The authors trained a model for classification of tumor on 746 skin biopsy slides and tested it on 15 Mohs surgery frozen sections. The authors estimated performance metrics and compared the regions of interest generated by the model with the original H&E slides. RESULTS The model achieved an AUC-ROC of 0.985 and 0.796 for tumor classification in permanent pathology and in frozen sections, respectively. Regions of interest for frozen sections with scarce tumor areas were inaccurate, focusing on normal tissue for slides classified as false negative, or highlighting structures different from tumor (e.g., inflammation, muscle, and nerves) for slides classified as true positive. CONCLUSION Deep anatomical structures more commonly present in Mohs frozen pathology might represent data out-of-distribution for models trained on permanent pathology, potentially leading to inadequate model outputs.
