Introduction: Early open fracture management aims to minimise the risk of complications. For the most severe open fracture wounds, multiple irrigation and debridement surgeries are required to overcome severe wound contamination, to reassess the evolving tissue injury or to temporise and plan further surgery. When multiple irrigation and debridement surgeries are needed, uncertainty remains about how the open fracture wound should be managed to best minimise complications. The primary aim of this trial is to compare the antibiotic cement bead pouch vs negative pressure wound therapy in the management of patients with severe open tibia fracture wounds.
Methods and analysis: …

Acute kidney injury (AKI) is a well-recognized complication of chimeric antigen receptor (CAR) T-cell therapy, typically attributed to cytokine release syndrome and acute tubular injury. However, glomerular disease post CAR-T cell is rare. We report a case of minimal change disease presenting with AKI and nephrotic-range proteinuria 3 weeks after B-cell maturation antigen-directed CAR-T cell therapy, ciltacabtagene autoleucel, in a patient with relapsed refractory multiple myeloma. The kidney biopsy revealed diffuse podocyte foot process effacement and a predominance of CD4+ T cells with potential on-target, off-tumor effect of B-cell maturation antigen-directed CAR-T cell therapy, leading to podocyte injury. The patient …

Background: Irreversible hydrocolloid (alginate) is widely used for dental impressions, but its poor dimensional stability over time limits accuracy when delays in pouring occur. Enhancing its stability through material modification, such as incorporating condensation silicone, may improve clinical outcomes.
Materials and methods: Three groups (n = 10) were evaluated: Group I (conventional alginate, Avagel), Group II (extended-pour alginate, Hydrogum 5), and Group III (alginate modified with condensation silicone). Specimens were fabricated using standardized molds and stored under controlled humidity. Dimensional stability was assessed at five time points (immediate, 24, 48, 72, and 120 h) by measuring mass and linear dimensions. …

Platelet-derived extracellular vesicles (PEVs) play an active role in vascular protection and repair and are being explored as a viable alternative to platelet therapy. Because platelet function and stability are shaped by donor sex and storage conditions, these same factors are likely to influence the PEVs they release. Understanding these influences is key to developing PEVs into a safe and dependable therapeutic option. In this study, we investigated how donor sex and platelet storage affect the therapeutic properties of PEVs. To address this, PEVs were isolated from platelets of healthy male and female donors. Platelets were either processed immediately after …

Background: Hemorrhagic shock (HS) following traumatic injury is hallmarked by innate immune activation, hypercoagulability, and thromboinflammatory complications. To date, the direct link between HS, injury severity, and endothelial cell (EC) contributions to thromboinflammation remains poorly understood. The goals of this study were to determine the impact of injury severity and HS on endothelial-mediated thromboinflammation and examine whether these changes increase the propensity for thrombosis.
Methods: Plasma from 89 male trauma patients, stratified by HS and injury severity, and 10 healthy subjects were assessed for inflammatory mediators by BioPlex. Human lung microvascular endothelial cells were exposed to patient plasma for 4 …

Background: Unlike in-house call, the Accreditation Council for Graduate Medical Education (ACGME) does not require a postcall day for "home call" shifts. Despite this, we hypothesize that on-call residents are still in the hospital for the majority of their shift despite having the luxury of home call and, thus, are not protected by ACGME postcall duty hour regulations.
Methods: A prospective single center survey study was conducted by surveying junior and senior residents who completed overnight call shifts from January 2023 to April 2023 at one of the busiest level 1 trauma centers in the United States. Data include number …

Tracking the emergence of new viral variants is critical for epidemic preparedness, but remains challenging because variants typically circulate at low prevalence during the early phase of outbreaks. Here, we present an integrated framework that combines sensitive variant detection in wastewater with quantitative assessment of transmissibility through dynamic epidemic modeling. Using the SARS-CoV-2 Omicron variant as a proof of concept, we developed a novel nested allele-specific RT-qPCR assay (NAS-PCR) that achieved a thousand-fold increase in sensitivity compared with allele-specific RT-qPCR (limit of detection: 0.5 copies/μl). NAS-PCR detected Omicron in wastewater samples from the Greater Boston area starting in September 2021, …

Covariate-specific and time-dependent area-under-curve (AUC) is often used to evaluate the discriminative performance of biomarkers with time-to-event outcomes, particularly when certain covariates influence biomarkers' accuracy. In biomarker research, despite extensive efforts, missing data remain unavoidable, with nonignorable missingness posing significant challenges. This article focuses on estimating the impact of covariates on time-dependent AUC in the presence of nonignorable missing biomarkers. Assuming a parametric model on the missing probability, we leverage instrumental variables to address the identifiable issue and estimate the unknown parameters. We integrate the inverse probability weighting approach into the score equation of a pseudo partial likelihood for estimation …

Purpose: Growth modulation is an established technique for limb deformity correction and is increasingly applied to spinal deformities. While distraction-based posterior and anterior compressive methods have been explored, spinal growth modulation through fixation across vertebral growth centers remains unstudied. We hypothesized that unilateral trans-endplate screws-spinal epiphysiodesis trajectory (SET) screws-could induce partial anterior growth arrest and promote scoliotic deformity in a porcine model.
Methods: Four male piglets (two experimental, two control) underwent unilateral posterior spinal instrumentation at four lower thoracic levels at eight weeks of age. Experimental animals received trans-endplate SET screws; controls received pedicle screws. Radiographs obtained three months postoperatively …

Objective: Ultrasound (US) has been proposed as a potential tool for assessing skin fibrosis in systemic sclerosis (SSc). However, a large-scale comparison of US-based assessment with histologic markers of skin fibrosis has not been reported. We evaluated US-based skin assessments for their face validity (differentiation between involved SSc and healthy control [HC] skin), construct validity (comparison to modified Rodnan skin score [mRSS]), and criterion validity (comparison to histologic and gene expression fibrosis markers).
Methods: Twenty HCs and 52 patients with SSc underwent clinical and US assessment followed by a forearm skin biopsy. Predefined areas were assessed on the finger, hand, …

Introduction: Past studies of hepatitis B vaccines in people with HIV (PWH) have shown mixed results about improving responses with increases in dose or dose frequency, leading to inconsistent guidelines and practice. We examined vaccine series completion and revaccinations in PWH lacking a seroprotective response.
Methods: Hepatitis B vaccination histories were evaluated as a retrospective study in 561 participants of A5379 trial (NCT04193189). Individuals in 41 sites in Africa, Asia, South America, and the United States qualified for the trial with antibody titers below the seroprotective level (< 10 mIU/mL) despite past hepatitis B vaccinations. The primary measure of interest was the number of vaccines in the past vaccination records.
Results: Of the 1098 trial candidates, 561 (51%) did not …

Objective: Sudden unexpected death in epilepsy (SUDEP) is a devastating consequence of some generalized convulsive seizures (GCS). Recent work has focused on seizure related apnea as a biomarker of SUDEP risk, frequently without characterizing the adequacy of non-apneic ventilation or identifying other dysfunctional breathing patterns. We hypothesized that GCS frequently induce immediate, severe, non-apneic respiratory dysfunction that can induce critical hypoxia and bradycardia and sought to characterize breathing patterns after GCS.
Methods: Adult patients admitted to an epilepsy monitoring unit were studied. The effects of GCS on breathing and heart rate were analyzed using nasal pressure transducers, chest and abdominal …

Phase-change nanodroplets (PCNDs) continue to generate significant research interest due to their potential to extravasate into tissue, to be targeted for molecular imaging and drug delivery, and to undergo an induced phase-change to "activated" microbubbles (MBs) for ultrasound (US) imaging. To accurately quantify molecular markers, however, one assumes a consistent proportion of PCNDs in a region of interest (ROI) are stably activated and imaged. Herein we present a framework for developing a diagnostic sequence that is optimized for PCND activation uniformity, contrast, and acquisition time. To develop this framework, activation was examined at three scales of increasing complexity: single, adjacent, …

Faculty, Staff and Student Publications
Background: Treatment of acromioclavicular joint (ACJ) separations continually lacks consensus between providers, and while low-grade injuries generally respond well to conservative management, high-grade injury management is more complex. For patients requiring surgery, the effect of the timing of surgery with respect to the original injury on clinical outcomes remains unclear.
Hypothesis: Clinical outcome measures would worsen as the time between ACJ dislocation injury and surgery increased.
Study design: Cohort study; Level of evidence, 3.
Methods: A large nationwide insurance claims database was queried for patients who had an ACJ dislocation injury using International Classification of Diseases, Ninth and Tenth Revision …

Limb salvage using free tissue transfer in patients with rare autoinflammatory syndromes is poorly described, and the safety of microvascular reconstruction in this population remains uncertain. Hereditary pyogenic arthritis, pyoderma gangrenosum, and acne (PAPA) syndrome is characterized by dysregulated inflammation, pathergy, and impaired wound healing, raising concern for flap compromise and postoperative complications. We report a rare case of lower extremity free tissue transfer in a patient with PAPA syndrome. A 66-year-old woman with rheumatoid arthritis and PAPA syndrome presented with rapid wound breakdown, violaceous ulceration, exposed hardware, and periprosthetic joint infection following left total knee arthroplasty (TKA). Examination revealed …

Exposure-based behavioral therapy, the most effective treatment for posttraumatic stress disorder (PTSD), also reduces depressive symptoms. However, neurobiological mechanisms underlying the beneficial effects of exposure-based behavioral therapy on depression remain unknown. Our lab has established fear extinction as a rat model of exposure therapy to investigate the mechanisms underlying its therapeutic behavioral effects in chronically stressed rats. In this study, we demonstrated that extinction learning reduced immobility in the forced-swim test and reversed chronic stress-induced reduction in sucrose preference. Chemogenetic inactivation of pyramidal neurons in the ventral medial prefrontal cortex (vmPFC) prevented these antidepressant-like effects of extinction. Extinction learning enhanced …

Introduction: Left upper quadrant (LUQ) drain use after trauma splenectomy varies, with minimal existing data to guide practice. We aimed to investigate the association of LUQ drains with organ space surgical site infection (OS-SSI) after splenectomy. We hypothesized that LUQ drains after trauma splenectomy are associated with increased odds of OS-SSI.
Patients and methods: A retrospective study of adult blunt trauma patients who underwent splenectomy from 7/2018 to 6/2024 was performed. We excluded patients who survived < 5 days after operation, and those with an intraoperatively identified pancreatic injury. Demographics, surgical details, and drain information were abstracted from the medical record. Inverse probability of treatment weighting (IPTW) was used to balance variables between patients who did and did not receive an LUQ drain after splenectomy. Multivariable logistic regression with IPTW was performed to estimate the association of LUQ drains with OS-SSI.
Results: Of 179 patients, 68% (n = 121) were male, the median age was 38 years (interquartile range 28, 55), and 27% (n = …

Importance: Surveillance of postacute sequelae of SARS-CoV-2 infection (PASC) depends on diagnostic coding systems that capture fewer than one-half of affected individuals, rendering millions invisible to health systems and policymakers.
Objective: To quantify the gap between true PASC burden and diagnostic code-based estimates, determine the proportion representing chronic disease, and characterize organ system heterogeneity and temporal trends across diverse populations.
Design, setting, and participants: This retrospective cohort study used electronic health record data from 58 hospitals and affiliated clinics in 4 US regions, from 2017 to 2025. Adults (aged ≥18 years) with laboratory-confirmed SARS-CoV-2 infection or a COVID-19 diagnosis code …
