Importance Circulating tumor human papillomavirus DNA (ctHPVDNA) is an important biomarker for the presence of HPV-associated oropharyngeal squamous cell carcinoma (OPSCC), but little is known about early postoperative kinetics of ctHPVDNA clearance. Objective To investigate early postoperative kinetics of ctHPVDNA in patients with HPV-associated OPSCC. Design, Setting, and Participants This prospective cohort study was conducted at a single tertiary care center from January 4, 2020, to January 26, 2023. Patients with newly diagnosed HPV-associated OPSCC undergoing surgical management were enrolled. HPV status was defined as positive if findings of p16 immunohistochemistry and/or HPV DNA in situ hybridization and/or E6/E7 RNA in situ hybridization were positive. Exclusion criteria included history of prior head and neck cancer and metastatic disease at presentation. Data were analyzed from September 1, 2024, to April 25, 2025. Exposures Transoral robotic surgery with concurrent neck dissection. Main Outcomes and Measures Blood was drawn prior to surgery (pretreatment), 1 to 2 days after surgery (postoperative days 1 to 2), and approximately 2 weeks after surgery (postoperative week 2; range, 8 to 20 days). ctHPVDNA was quantified by a tumor tissue–modified viral (TTMV) HPV DNA test. Correlations were tested between the pretreatment and postoperative day 1 to 2 TTMV HPV DNA levels using Gaussian regression. Concordance between detectability at postoperative day 1 to 2 and postoperative week 2 was explored using negative predictive value and positive predictive value. Results Of 57 included patients with detectable pretreatment TTMV HPV DNA, 51 (89%) were male, and the median (IQR) age was 59 (54-66) years. A total of 35 patients (61%) had blood draws at all 3 time points; 16 (28%) had detectable TTMV HPV DNA on postoperative day 1 to 2. Pretreatment and postoperative day 1 to 2 TTMV HPV DNA levels had a medium positive linear correlation ( r = 0.31; 95% CI, 0.04-0.54). Undetectable TTMV HPV DNA on postoperative day 1 to 2 blood draw had a negative predictive value of 0.95 (95% CI, 0.74-1.00) for an undetectable level on postoperative week 2 blood draw, but a detectable level on postoperative day 1 to 2 blood draw only had a positive predictive value of 0.19 (95% CI, 0.04-0.46). Of the 16 patients with detectable TTMV HPV DNA pretreatment and at postoperative day 1 to 2, only 3 (19%) continued to have detectable TTMV HPV DNA at postoperative week 2. One patient had undetectable levels at postoperative day 1 to 2 and detectable levels at postoperative week 2. Conclusions and Relevance In this study, ctHPVDNA detectability early after surgery did not predict detectability at 2 weeks after surgery. ctHPVDNA clearance early after surgery could predict a negative test at 2 weeks. A negative blood draw finding on postoperative day 1 may be used to omit a postoperative blood draw at 2 weeks for minimal residual disease detection in future clinical trials.

Purpose The aim of part-one of this EU-US consensus was to combine literature research and expertise to provide recommendations for the usage of rehabilitation (including physical therapy) of patients undergoing surgical treatment for degenerative meniscus lesions or acute meniscus tears (including meniscectomy, repair, or reconstruction). Prevention programs, non-operative treatment of acute tears and degenerative lesions, return to sports and patient-reported outcome measures (PROMS) will be presented in a part-II article. Methods This consensus followed ESSKA “formal consensus” methodology. For this combined ESSKA (European Society for Sports Traumatology and Arthroscopy), AOSSM (American Orthopedic Society for Sports Medicine), ASSPT (American Academy of Sports Physical Therapy) initiative, 67 experts (26 in the steering group and 41 in the rating group) from 14 countries (USA and 13 European countries) including orthopedic surgeons, sports medicine doctors and physiotherapists were involved. Steering group members established guiding questions, searched the literature, proposed statements. Rating group members assessed the statements according to a Likert scale and provided grades of recommendations reaching final agreement about rehabilitation of the knee after meniscus surgery. Final documents were then assessed by a peer review group to adress the geographical adaptability. Results The overall level of evidence of the literature was low. Of the 19 questions (leading to 29 statements), one received a grade A of recommendation, two a grade B, nine a grade C and 17 a Grade D. Nevertheless, the mean median rating of all questions was 8.2/9 (9 being the highest rating on a scale of 1-9) and the global mean rating was 8.4+/-0.2, indicating a high agreement. Rehabilitation depends on the type of lesion, the treatment performed and is the same after medial or lateral meniscus surgery. Rehabilitation after meniscectomy should follow a criterion-based rehabilitation protocol, based on milestones rather than a time-based protocol. After meniscus repair and reconstruction, rehabilitation should be progressed according to both time and criterion-based milestones. Conclusion Rehabilitation after meniscus surgery is a debated topic that may influence surgical outcomes if not optimally performed. This international formal consensus established clear, updated, and structured recommendations for both surgeons and physiotherapists treating patients after meniscus surgery.

Abstract RATIONALE: Susceptibility to severe COVID-19 and long COVID may be influenced by pre-existing lung structure. ECG-gated, non-contrast cardiac CT scans, originally acquired for assessing coronary artery calcium, are available in multiple longitudinal cohort studies and have been previously validated against lung CT scans for densitometry; however, protocol variation across cohorts may hinder direct comparison. To address this, we developed a quality control (QC) rubric to grade cardiac CT scans for standardized quantitative lung measures across cohorts. METHODS: C4R assessed SARS-CoV-2 infection and outcomes in 14 NHLBI cohorts, of which 10 (six community-based and four longitudinal case-control studies) included CT scans (12,459 participants with lung and 13,752 with cardiac CTs). Logic rules were applied to categorize scans (Table): Grade “A-B” scans had 2-3.5mm slice thickness, at least 20 axial slices, no lung cropping in axial view and lung and airway volumes greater than the cohort-specific 1st percentile. “C-D” scans had one lung obscured by cropping around the heart, so quantitative measures were restricted to the lung in complete view. “F-H” scans were deemed unusable, suffering from low slice count (<20), severe image cropping, low lung or airway volumes (< 1st%ile). Visual inspection was performed on a sample from each category to ensure accuracy. Percent of lung voxels in low attenuation areas < -950 HU (LAA950), high attenuation areas (-600 to -250 HU, HAA) and 15th percentile HU value (perc15) were measured. Within-participant variability was quantified using the intraclass correlation coefficient (ICC). RESULTS: We performed QC on cardiac CT scans from an initial sample of 6,275 participants from three C4R cohorts (ARIC, CARDIA, MASALA), imaged with GE or Siemens scanners. Of these, 5,125 (81.7%) were graded “A-B”, 496 (7.9%) were “C-D” and 654 (10.4%) were “F-H”. The percentage of “F-H” scans varied widely across cohorts [<1% to 26%] due to image cropping. Among the 5,621 cardiac CT scans graded A-D, the mean±SD for LAA950, HAA and perc15 respectively were 1.1±2.1%, 7.2±4.7% and -887±33 HU. Repeated imaging was available for 107 participants (time interval 5.1±0.7y). For paired scans in grades A-B (n=101/107), the within-participant correlation for LAA950, HAA and perc15 were 0.91, 0.38 and 0.74 respectively. CONCLUSION: Initial application of QC to cardiac CT scans identified scans with high reproducibility, with the aim to provide valid quantitative lung metrics on over 20,000 highly characterized participants in C4R.

Abstract Rationale: Propofol can increase the risk of hypertriglyceridemia and subsequent pancreatitis in critically ill patients. It is unclear whether modifying or continuing sedation regimens in patients experiencing hypertriglyceridemia while on propofol infusion influences the development of adverse events such as acute pancreatitis. This study compared the clinical outcomes of patients receiving invasive mechanical ventilation (IMV) who had their propofol regimen modified versus continued following the detection of hypertriglyceridemia. Methods: A targeted trial emulation was conducted using retrospective data from 5 Mayo Clinic hospitals between 05/05/2018 and 06/30/2023. Inclusion criteria included: 1) receiving IMV and continuous propofol infusion for >24 hours, 2) experiencing triglyceride level >400 mg/dL while on propofol, and 3) still requiring IMV at 24-hours after hypertriglyceridemia onset. Patients were then categorized based on whether they had their propofol regimen modified (i.e., dose reduction by ≥50% or any reduction with alternative sedatives started) versus continued (no reduction or <50% reduction without alternative sedative initiation). Outcomes included 30-day ventilator-free days, successful extubation, acute pancreatitis (determined by chart review, in-duplicate), ICU and hospital length of stay, 30- and 90-days alive and at home, as well as all-cause mortality. Analyses were conducted using stabilized inverse probability of treatment weights with adjustments for covariates selected a priori. Sensitivity analyses, where only benzodiazepines or benzodiazepines and ketamine were considered to be eligible alternative sedatives, were done. Results: During the study period, 728 patients were included, of whom 422 had their propofol regimen modified (Image). The two groups had similar demographics, comorbidities, and illness severity. We identified 14 cases of acute pancreatitis possibly attributable to propofol, with 9 cases in the modified and 5 cases in the continued regimen group (2.1% versus 1.6%; P=0.63). Following adjustment for covariates, there were no significant differences in any outcomes of interest. After censoring for mortality, there was no significant difference in the 30-day cumulative incidence of successful extubation when comparing those with their regimen modified versus continued (Hazard ratio [HR] 0.95; 95% confidence intervals [CI] 0.77 to 1.18; P=0.70). There was also no significant difference in the 90-day survival rate between the two groups (HR 0.89; 95% CI 0.71 to 1.11; P=0.34). These findings remained consistent upon sensitivity analyses. Conclusion: There were no differences in outcomes among patients who had their propofol regimens modified versus continued following the detection of hypertriglyceridemia. Further prospective investigations are needed to identify the optimal strategy for managing sedative regimens in this patient population.

Abstract Rational: Talc pleurodesis is an effective intervention for preventing recurrent pleural effusions and pneumothoraces, particularly in non-surgical candidates. Due to its efficacy and safety, it is recommended as the most effective sclerosant for pleurodesis. However, in some cases, the initial pleurodesis fails, necessitating a repeat procedure. The efficacy of repeat talc pleurodesis after an initial failure is an area that requires further exploration. This study explores the safety and efficacy of repeat talc pleurodesis among patients who did not respond to the initial intervention. Methods: This retrospective study analyzed hospitalized patients who underwent 4g talc slurry pleurodesis from 2019 to 2024, focusing on demographics, comorbidities, initial pleurodesis failure, and recurrence rates. Pleurodesis failure was identified by lung sliding, recurrent effusion, or pneumothorax during the same hospitalization. The primary outcome was recurrence post-discharge, assessed by pleural effusion or pneumothorax within 180 days post-repeat pleurodesis. Results: This study included 94 patients (52.1% male, 47.9% female) with a mean age of 67.6. Among them, 79 (84%) received a single 4g dose of talc, while 15 (16%) received multiple 4g talc doses for initial pleurodesis. Recurrence occurred in 20 (25.3%) of the single-dose group and 1 (6.7%) of the multiple-dose group within 180 days, though the difference was not statistically significant (p=0.112). Recurrence-free rates were 93.6% at 30 days, 85.1% at 90 days, and 77.7% at 180 days. Of the 20 patients with recurrence after a single 4g dose of talc, 8 (40%) underwent repeat pleurodesis, with only one recurrence requiring surgical intervention. Additionally, there was no recurrence after repeat talc pleurodesis in the one patient with recurrence after receiving multiple 4g talc doses for initial pleurodesis. No associations were found between recurrence rates and factors like gender (p=0.213) or comorbidities (emphysema, COPD, lung malignancy). Chest pain was a common complaint, but no cases of respiratory distress were reported post-pleurodesis. Conclusion: The efficacy of initial talc pleurodesis (77.7%-93.6%) in this cohort aligns with existing literature. Multiple-dose talc pleurodesis effectively prevented recurrence in 93.3% of patients, with no reported respiratory distress. Additionally, repeat talc pleurodesis was successful in 87.5% of those with recurrence after an initial single 4g dose. These findings support multiple-dose talc pleurodesis and repeat talc pleurodesis as safe and effective options for preventing recurrence post-initial failure and post-repeat talc pleurodesis, respectively. Although no significant recurrence predictors were identified, future research could focus on patient-specific factors to enhance treatment selection and optimize outcomes.

Abstract Rationale: Airway-stenosing disease is a significant clinical problem in multiple populations. While the immediate endoscopic and clinical response to bronchoscopic interventions are high, rates of clinically significant recurrence are elevated, and often require multiple and frequent reinterventions. Newer strategies to prevent recurrence of central and proximal airway stenosis are needed. Methods: Retrospective review of bronchoscopic balloon bronchoplasties performed at the Mayo Clinic utilizing paclitaxel coated balloons (PCB) in 2023-2024 for recurrent airway stenosis. IN.PACT Admiral and AV balloons (sizes 5-12 mm, 3.5 mcg/mm2 paclitaxel dose) were used with an inflation time of 2-3 minutes. Procedural success was defined as <50% airway stenosis or resolution of the procedural indication. Reintervention was considered only if a therapeutic bronchoscopy was subsequently required to address the same lesion treated with PCB. Only patients with follow-ups >90 days were included in the reintervention inter-procedural time analysis. Results: Thirty-three procedures were performed in 18 patients. Seventeen (51%) for lung transplantation-associated stenosis (29% anastomotic/perianastomotic, 76% lobar and segmental stenoses), 8 (24%) for granulomatous polyangiitis-associated stenosis, 3 for postintubation tracheal stenosis and 2 for chemical/pill injury. Eighteen cases (54%) utilized an additional dilation modality (12 non-coated balloon dilation, 4 rigid dilation), 5 spray cryotherapy, 6 other ablative therapies (4 CO2-laser, 2 electrocautery cuts), and 6 received an airway stent during the same procedure. 57% percent of interventions occurred in the lobar, 27% mainstem/bronchus intermedius, 9% tracheal, 7% segmental airways. Thirty-one (93%) cases had a satisfactory initial endoscopic result. The median number of bronchoscopic therapeutic interventions required before the use pf PCB was 5 (IQR 2.5-11.5), which significantly decreased to 0.1 (IQR 0-1, range 0-9) after PCB (p <0.001). The reintervention-free survival significantly increased after PCB dilation from a median 35 days (IQR 28.7-80.5) to 132 days (IQR 64-197; p=0.004). Twenty-one cases required subsequent bronchoscopies, sixteen (76%) of which demonstrated improvement in lesion severity when compared to the results of prior interventions. Only 16 (48%) required therapeutically addressing the same lesion. Only 2 minor complications occurred (6%, self-limited bleeding and unplanned admission), none related to paclitaxel use. Six-month mortality was 3% from an unrelated cause. Conclusions: The locoregional antiproliferative effects of paclitaxel show promise in preventing recurrence, minimizing the need for repeat procedures, and extending intervals between interventions in patients with recurrent, predominantly benign airway stenosis. Its use is feasible, safe, and future research is warranted, particularly comparing PCB with the currently available strategies.

ObjectiveA dysregulated immune response is involved in the pathogenesis of polymyalgia rheumatica (PMR) and giant cell arteritis (GCA). These diseases have been reported as immune‐related adverse events in patients with cancer treated with immune checkpoints inhibitors. In this cross‐sectional study, the relationship between soluble immune checkpoint molecules (sICMs) and clinical/imaging features of PMR and GCA was investigated.MethodsConsecutive patients with PMR diagnosed according to the criteria by Bird et al were compared with age‐ and sex‐matched healthy controls. Patients with PMR and overlapping GCA had to also satisfy the 1990 ACR classification criteria for GCA. All patients underwent standardized clinical, laboratory examination, and 18F‐fluorodeoxyglucose positron emission tomography/computed tomography scans. The sICM anticytotoxic T Ly‐4, the programmed cell death protein 1 (PD‐1), and PD‐1 ligands PD‐L1 and PD‐L2 were measured by enzyme‐linked immunosorbent assay.ResultsForty patients (80% women, mean age 76 years, and mean disease duration 88 days) were assessed. Of these, 30 had isolated PMR and 10 had PMR with GCA. Patients showed significantly higher concentrations of all sICMs compared with controls (P < 0.001). Conditional logistic regression revealed the strong discriminative capacity of these molecules between patients and healthy controls, with PD‐1 showing complete separation among groups (effect size = 0.78) and PD‐L1 (odds ratio [OR] 134.33, P < 0.001) and PD‐L2 (OR 63.00, P < 0.001) demonstrating the strongest ability to distinguish patients from controls. Correlations between sICM levels and clinical features were generally weak or absent, with no significant differences based on disease phenotype or glucocorticoid exposure. Results were similar in glucocorticoid‐naive patients.ConclusionsICMs are significantly elevated in PMR and GCA and strongly differentiate patients from healthy controls. Although they do not correlate with clinical or imaging features, their consistent elevation in active disease might suggest a complex interplay between innate and adaptive immunity.image
