BACKGROUND:The purpose of this systematic review is to evaluate the clinical outcomes, complication rates, and failure rates following platelet-rich plasma (PRP) injections for lateral ankle ligament injuries. METHODS:During June 2025, a systematic review of the PubMed, EMBASE, and Cochrane Library databases was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines to identify comparative clinical studies evaluating PRP for lateral ankle ligament injuries. Data extracted included patient demographics, clinical outcomes, complications, failures, and secondary procedure rates. RESULTS:Five studies were included involving a total of 126 patients (126 ankles) who received PRP injections and 48 patients (48 ankles) who were in the control cohort, with a mean follow-up of 7.1 ± 4.3 months. Across studies, no consistent differences were found in clinical outcome scores between PRP and control cohorts at short-term follow-up. Significant heterogeneity in PRP preparation and administration protocols precluded a pooled meta-analysis from being performed. Platelet-rich plasma injections were associated with low complication (3.4%) and failure (5.1%) rates, and no secondary procedures were reported. Overall, the certainty of the available evidence was low, representing a limited and heterogeneous evidence base. CONCLUSION/CONCLUSIONS:Based on limited short-term data, the available studies do not demonstrate a clear or consistent difference in clinical outcomes between PRP-treated patients and controls. However, the evidence base is scarce, highly heterogeneous, and of low certainty. Substantial variability in PRP preparation and administration, small sample sizes, and short follow-up preclude reliable quantitative synthesis and comparative conclusions. Consequently, the current literature is insufficient to determine whether PRP provides any clinical advantage over standard care for lateral ankle ligament injuries. Further well-designed, adequately powered prospective studies with standardized PRP protocols and longer follow-up are warranted. LEVEL OF EVIDENCE/METHODS:

OBJECTIVE/UNASSIGNED:Violence against healthcare workers (HCWs), especially in emergency departments and trauma centers (TCs), is a significant and growing problem. HCWs have the highest numbers and annual rates of workplace violence (WPV) compared with any other private industry sector. There is less information about the rates of violence and stalking against trauma providers in TCs. We hypothesized that a majority of trauma surgeons and team members have experienced deliberate assaults in their TCs. Our secondary hypothesis was that a majority of trauma providers consider WPV a significant issue in their workplace. METHODS/UNASSIGNED:The American Association for Surgery of Trauma Disaster Committee invited 2,100 members to participate in an online survey in May and July 2024. Questions evaluated practice type, TC characteristics, training, experience with WPV, beliefs about WPV prevention, and potential WPV prevention strategies interventions. RESULTS/UNASSIGNED:The survey response rate was 10.9%, yet the prevalence of WPV in TCs was reported to be high. 63.9% of respondents were aware of a deliberate assault on an HCW in their TC or system. 42.5% had been assaulted personally, and 7.5% suffered injury as a result of a deliberate assault. Respondents generally agreed on the need for WPV prevention measures such as prevention education, metal detectors, armed police, or security, and were aware of deaths and disabilities among HCWs after assaults. However, they did not personally see WPV as a significant issue in their TCs. CONCLUSIONS/UNASSIGNED:There is a high prevalence of WPV with significant effects on the entire trauma workforce, including elevated levels of emotional distress, burnout, post-traumatic stress disorder, and long-term irreversible physical injuries and deaths. Respondents agreed on the need for preventive measures but did not view WPV as a major issue in their own TCs. Research into this discrepancy, as well as effective strategies to reduce WPV in TCs, would support advocacy for improved legislation and policies aimed at preventing WPV in healthcare. LEVEL OF EVIDENCE/UNASSIGNED:V - Survey of expert opinion.

Complex extremity wounds, if not addressed properly, are a leading cause of major limb amputation. Chronic wounds in salvaged extremities contribute to long-term morbidity in the extremity. Orthoplastic surgery treats limb-threatening conditions through the combined application of orthopaedic and plastic surgical principles, applied to clinical problems simultaneously. Key components include early stakeholder evaluation of the limb and patient and open collaborative communication between orthopaedic and plastic surgeons. Meticulous débridement at the time of presentation and careful selection of fixation informed by the overall reconstructive plan should be executed when the patient presents to the emergency department. Implementation of Orthoplastic protocols results in quicker time to skeletal stabilization and soft tissue coverage, reduced risk of infection, improved functional outcomes, and less cost for care. This review presents a protocol-driven guide for establishing an Orthoplastic program and optimizing limb salvage outcomes across diverse practice settings.

BACKGROUND AND STUDY AIMS/UNASSIGNED:Cholangiocarcinoma (CCa) is a complex malignancy of the biliary tract, classified as intrahepatic, perihilar, or distal. Digital single-operator cholangioscopy (D-SOC) enhances evaluation of biliary strictures, although it remains limited by suboptimal biopsy yield and technical constraints. Artificial intelligence (AI), particularly convolutional neural networks (CNNs), has emerged as a promising adjunct. However, performance across anatomical subtypes is not well defined. This study evaluated diagnostic performance of an AI-based model in detecting CCa lesions by location. PATIENTS AND METHODS/UNASSIGNED:A YOLOv8-based CNN was trained and validated using 315,993 D-SOC images from 183 patients across six international high-volume centers. Images were labeled as benign or malignant based on expert consensus. Frame-based analysis assessed diagnostic performance using macro-average F1-score, precision, and recall. Subgroup analysis explored anatomical site-specific performance. RESULTS/UNASSIGNED:Among the included patients (mean age 66.1±12.1 years; 64.5% male), 43.2% had perihilar, 37.2% intrahepatic, and 19.7% distal biliary strictures. The model demonstrated high overall performance: F1 score 95.3%, precision 95.5%, and recall 95.1%. Site-specific analysis revealed an F1 score of 89.6% for distal strictures and 91.1% for perihilar strictures. Receiver operating characteristic curves showed areas under the curve of 0.980 for intrahepatic strictures and 0.990 for perihilar and distal strictures. CONCLUSIONS/UNASSIGNED:This is the first study to demonstrate AI-based diagnostic performance across CCa topography using a large, multicenter D-SOC dataset. Although anatomical complexity affects detection, the model's high precision and generalizability suggest potential for clinical utility. These results support application of an AI-enhanced algorithm decision algorithm for cholangioscopy.

BACKGROUND:In expert centers, surgical resection rates of locally advanced pancreatic cancer (LAPC) following induction chemotherapy have increased beyond 20% with subsequent 25% five-year overall survival (OS). In the Netherlands, however, the historical low 8% LAPC resection rate compared with 23% in international expert centers reflects relative reluctance. Thereby, opportunities to achieve long-term survival in appropriately selected patients may be missed. This study evaluated whether nationwide implementation of international multidisciplinary best-practice for LAPC management is feasible while maintaining surgical safety benchmarks (in-hospital/30-day major morbidity <50% and mortality ≤5%). METHODS:A multidisciplinary protocol was designed in collaboration with four international experts and prospectively implemented nationwide within the Dutch Pancreatic Cancer Group (DPCG) (2022-2024). This observational cohort included consecutive patients diagnosed with LAPC, defined by DPCG criteria. Eligible patients had radiologically non-progressive disease after at least four months of multi-agent chemotherapy. All patients who underwent resection were included in this safety analysis. A predefined sub-group analysis included patients with National Comprehensive Cancer Network (NCCN) LAPC. Primary outcomes included in-hospital/30-day major morbidity (i.e., Clavien-Dindo grade ≥IIIa) and mortality. The expected number of resections was 53. RESULTS:Overall, 180 patients with LAPC underwent surgical exploration, of whom 155 (86%) underwent resection in 11 centers. Most (74%) resections were performed in the three LAPC surgical centers. Extended resections were performed in 77% of patients, including portomesenteric venous (60%), multivisceral (23%), and arterial (21%) resections. In-hospital/30-day major morbidity rate was 44% and mortality rate was 0.6%, both within pre-established safety benchmarks. Benchmarks were also reached for patients with NCCN LAPC (49% major morbidity, 2% mortality). CONCLUSION/CONCLUSIONS:Nationwide implementation of the international best-practice for LAPC was feasible with nearly three times more resections performed than expected, while morbidity and mortality remained well within predefined safety benchmarks.

INTRODUCTION/BACKGROUND:Contemporary abdominal wall reconstruction places a strong emphasis on optimizing extraperitoneal mesh placement. When the posterior layer is insufficient for closure, adjuncts such as hernia sac, omentum, or Vicryl mesh have been described. The outcomes of various posterior layer supplementation (PLS) materials, both autologous and non-autologous, have not been well examined. We aim to evaluate the outcomes of patients undergoing ventral hernia repair with extraperitoneal mesh placement who undergo PLS and compare how PLS materials impact these outcomes. METHODS:All patients who underwent a retromuscular hernia (RM) repair with PLS between Jan 2021 and Jan 2025 at a single center were reviewed. Patient demographics, preoperative characteristics, intraoperative factors, and postoperative outcomes were evaluated. Descriptive statistics and comparative tests including Mann-Whitney U test, Student's t-test, and Fisher's exact test were utilized. RESULTS:Sixty-seven patients underwent RM repair with PLS. Supplement materials used included hernia sac, omentum, falciform ligament, prior mesh, new biologic, and biosynthetic coated mesh. Fifty-two percent (n = 35) of the repairs were retrorectus only and 48% (n = 32) were transversus abdominus releases. The average length of follow-up was 189 days with a recurrence rate of 3%. Sixty percent of PLS was performed with autologous material with 40% utilizing new biologic or biosynthetic coated meshes. SSI, SSO, and SSOPI were similar between the autologous and non-autologous supplementation groups (p = 1, p = 0.16, p = 0.29, respectively). There were more postoperative bowel obstructions in the non-autologous group (n = 4) as compared to the autologous group (n = 0) (p = 0.02). All the bowel obstructions were managed nonoperatively. DISCUSSION/CONCLUSIONS:Our findings suggest that outcomes are acceptable with minimal morbidity when comparing autologous tissue to biologic and biosynthetic coated mesh for PLS. The low recurrence rates observed, regardless of the material used, support the continued adoption of this approach. Proactive supplementation of the visceral sac may decrease need for lateral myofascial release.

OBJECTIVE:Our objectives were to understand migraine-related perceptions among college students and the lived experiences of those with migraine on college campuses and to generate recommendations for supporting college students with migraine. BACKGROUND:During young adulthood, there is a sharp growth in migraine prevalence and disability-adjusted life years. Migraine prevalence is approximately 16% among university students and negatively influences several aspects of a student's college experience. METHODS:This was a qualitative study using phenomenological inquiry via virtual semistructured focus groups. Recruitment took place between April 2025 and July 2025. An initial 60-min focus group was conducted in May 2025 with an all-women's college to assess our questions' relevance and comprehensiveness. We then conducted four national focus groups in June 2025 and July 2025 with college students from across the United States. All focus groups included students with and without severe headache or migraine (self-reported). Focus groups were transcribed and independently coded twice. We developed themes for the five focus groups using content analysis. Qualitative analysis was conducted between July 2025 and September 2025. RESULTS:Three students attended the all-women's college focus group and 47 students attended one of the four national focus groups (n = 50). The following themes emerged from the five focus groups: (1) Migraine is often misunderstood and not discussed on campus, with misconceptions surrounding severity and its distinction from headache. (2) The impact of migraine on campus is significant, with students reporting various triggering environments, difficulty maintaining focus, attending class, performing academically, preserving social relationships, and participating in extracurricular activities. (3) The most commonly reported accommodations for migraine were academic, specifically exam- and attendance-related, though not always honored by professors. (4) Access to migraine care for students is challenging, with reports that student health centers are typically unapproachable, inconvenient, and unhelpful, with students seeking external providers for migraine. Students recommended more awareness and education initiatives for improved understanding of migraine as well as increased access to migraine resources and accommodations. CONCLUSION/CONCLUSIONS:The experiences captured in our study provide unique qualitative insights by highlighting how misunderstanding of migraine on campus contributes to social and academic challenges faced by students with migraine. Students described unmet needs related to widespread misunderstanding of migraine, limited academic flexibility, environmental triggers, limited access to care, and inconsistent implementation of accommodations, highlighting that greater awareness of migraine, especially by professors and student health services, is crucial on college campuses. There are opportunities for migraine education programs on college campuses to increase knowledge and awareness about migraine and create a more supportive migraine environment.

INTRODUCTION/UNASSIGNED:There is uncertainty about the benefits of cerclage in patients with transvaginal cervical length (TVCL) ≤10 mm and no prior spontaneous preterm birth. Our aim was to assess whether cervical cerclage in these patients was associated with prolonged pregnancy latency. METHODS/UNASSIGNED:This was an observational study of asymptomatic singleton pregnancies without a history of spontaneous preterm birth with extremely short cervix (TVCL ≤10 mm) in the second trimester. Exposure and outcome data were extracted manually from medical charts by obstetric providers, with all outcomes occurring prior to study initiation. All patients were prescribed vaginal progesterone and those with a cervical dilation >1.5 cm were excluded. The primary outcome was time interval from diagnosis to delivery (or 37 weeks' gestation, whichever occurred first). Secondary outcomes included gestational age at delivery, mode of delivery, and neonatal outcomes. We adjusted for parity and used log-binomial regression to estimate the relative risk for categorical variables and linear regression to estimate mean differences for continuous variables. RESULTS/UNASSIGNED:There were 247 patients with TVCL ≤10 mm during anatomy scan. After exclusions, 87 remained, of which 55 (63.2%) received cervical cerclage. At the time of diagnosis, the mean cervical length was 5.8 mm (cerclage group) versus 7.4mm (no cerclage group, difference: -1.6, 95% CI -0.6, -2.6) and the gestational age was 21.0 weeks (cerclage group) versus 22.1 weeks (no cerclage group, -1.1, 95% CI -1.8, -0.3). Mean pregnancy latency was longer in the cerclage group compared to the no cerclage group (13.4 vs 11.1 weeks, 2.2, 95% CI -0.3, 4.9), though there was a high level of uncertainty in the estimate. Term delivery occurred 30% more often in the cerclage group compared to the no cerclage group (RR 1.31, 95% CI 0.96, 1.79). CONCLUSION/UNASSIGNED:In our cohort, patients with extremely short cervix who received a cerclage had longer pregnancy latency than those who did not receive cerclage and more patients achieved term gestation, suggesting a potential benefit of cerclage in this population. However, given the high level of uncertainty of our estimates, additional research is needed to investigate these findings.
