RESUMO

BACKGROUND: Radiologic occult metastatic disease (ROMD) in patients with pancreatic ductal adenocarcinoma (PDAC) who undergo contemporary neoadjuvant chemotherapy (NAC) has not been well studied. This study sought to analyze the incidence, risk factors, and oncologic outcomes for patients who underwent the NAC approach for PDAC. METHODS: A retrospective review analyzed a prospectively maintained database of patients who had potentially resectable PDAC treated with NAC and were offered pancreatectomy at our institution from 2011 to 2022. Multivariable regression analysis was performed to assess risk factors associated with ROMD. Kaplan-Meier curves with log-rank analyses were generated to estimate time-to-event end points. RESULTS: The study enrolled 366 patients. Upfront and borderline resectable anatomic staging comprised 80% of the cohort, whereas 20% had locally advanced disease. The most common NAC regimen was FOLFIRINOX (n = 274, 75%). For 55 patients (15%) who harbored ROMD, the most common site was liver-only metastases (n = 33, 60%). The independent risk factors for ROMD were increasing CA19-9 levels during NAC (odds ratio [OR], 7.01; confidence interval [CI], 1.97-24.96; p = 0.008), indeterminate liver lesions (OR, 2.19; CI, 1.09-4.39; p = 0.028), and enlarged para-aortic lymph nodes (OR, 6.87; CI, 2.07-22.74; p = 0.002) on preoperative cross-sectional imaging. Receipt of palliative chemotherapy (p < 0.001) and eventual formal pancreatectomy (p = 0.04) were associated with survival benefit in the log-rank analysis. The median overall survival (OS) of the patients with ROMD was nearly 15 months from the initial diagnosis, with radiologic evidence of metastases occurring after a median of 2 months. CONCLUSIONS: Radiologic occult metastatic disease remains a clinical challenge associated with poor outcomes for patients who have PDAC treated with multi-agent NAC.

RESUMO

Understanding and managing the complexity of trauma-induced thrombo-inflammation necessitates an innovative, data-driven approach. This study leveraged a trans-omics analysis of longitudinal samples from trauma patients to illuminate molecular endotypes and trajectories that underpin patient outcomes, transcending traditional demographic and physiological characterizations. We hypothesize that trans-omics profiling reveals underlying clinical differences in severely injured patients that may present with similar clinical characteristics but ultimately have very different responses to treatment and clinical outcomes. Here we used proteomics and metabolomics to profile 759 of longitudinal plasma samples from 118 patients at 11 time points and 97 control subjects. Results were used to define distinct patient states through data reduction techniques. The patient groups were stratified based on their shock severity and injury severity score, revealing a spectrum of responses to trauma and treatment that are fundamentally tied to their unique underlying biology. Ensemble models were then employed, demonstrating the predictive power of these molecular signatures with area under the receiver operating curves of 80 to 94% for key outcomes such as INR, ICU-free days, ventilator-free days, acute lung injury, massive transfusion, and death. The molecularly defined endotypes and trajectories provide an unprecedented lens to understand and potentially guide trauma patient management, opening a path towards precision medicine. This strategy presents a transformative framework that aligns with our understanding that trauma patients, despite similar clinical presentations, might harbor vastly different biological responses and outcomes.

RESUMO

BACKGROUND: Surgical mesh and hernia repair have come under increasing scrutiny with large amounts of press, Internet, and social media reportage regarding ongoing mesh litigation, recalls, and patient testimonials. The aim of this study was to evaluate patient perceptions of mesh in hernia surgery. METHODS: A 16-question survey was given to patients presenting for hernia surgery at a tertiary hernia center by trained data analysts before surgeon interaction. RESULTS: Two hundred and two patients were surveyed. Patients believed mesh caused complications (45.1%) and reported concerns about mesh (38.2%). Those who performed their own research, females, and patients with recurrent hernias were more likely to have concerns about mesh (P ≤ 0.03). Most patients (81.7%) thought they were at average risk or less for complications; patients with recurrent hernias (versus primary hernias) and incisional hernias (compared with inguinal or umbilical hernias) had more negative outlooks on complications (all P < .05). Recovery expectations varied, but the failed repair and incisional hernia groups were more likely to expect prolonged recovery (>3 months) (all P < .05). After surgeon-directed education and a mesh education handout, all but one patient agreed to and underwent a mesh repair as indicated. CONCLUSION: Patients had concerns about mesh and were aware of mesh related complications. Patients performing their own research, as well as females and recurrent hernia patients, had worse perceptions of mesh. Recurrent and incisional hernia patients had greater concerns about complications, recurrence, and recovery. Preoperative education concerning mesh and mesh choice for each operation eased patient anxiety.

RESUMO

BACKGROUND: The opioid epidemic has reached a crisis level in America, and many institutions are implementing new guidelines to decrease opioid prescriptions. Although these may positively impact opioid addiction, its influence on patient satisfaction is inadequately described. The aim of the study was to evaluate the effect of standardized patient education and postoperative opioid regimens on patient satisfaction. METHODS: General surgery patients were counselled and given educational materials preoperatively regarding postoperative pain management. Inpatient discharge prescriptions were based on milligrams of oral narcotic required 24 hours before discharge. Outpatient procedure prescriptions were standardized. Postoperatively, patients received surveys regarding pain control and satisfaction. RESULTS: Of the 198 patients studied, 96% agreed or strongly agreed that they were satisfied with their pain control. 92% agreed or strongly agreed they received enough medication; 7% disagreed, and 1% strongly disagreed. Educational materials were evaluated with 97% agreeing or strongly agreeing they received appropriate information concerning when and what to take. Fifty-five patients (28%) refused opioids or did not take any. Only 10 (5%) requested a refill. CONCLUSION: Preoperative education and standardized postoperative narcotic prescribing can be highly effective while maintaining high patient satisfaction. Introduction across broad fields of surgery will allow uniformity for surgeons, trainees, nurses, pharmacists, and patients.
