BACKGROUND AND OBJECTIVE/OBJECTIVE:Alcohol withdrawal syndrome (AWS) is a serious complication of alcohol use disorder. Although benzodiazepines are the mainstay of treatment, some patients may be resistant to them, requiring rapidly escalating doses. Phenobarbital has emerged as an effective adjunct therapy in severe alcohol withdrawal, but studies have yielded inconsistent results and carry safety risks. The purpose of our study was to examine the effectiveness and the potential harm of phenobarbital in AWS. METHODS:In this multi-center, retrospective cohort study, patients who were admitted for AWS and received phenobarbital with benzodiazepine were compared to patients who received benzodiazepine monotherapy. The primary outcome was time to AWS resolution. Other secondary and safety outcomes included length of stay (LOS), rate of mechanical ventilation, and incidence of aspiration pneumonia. RESULTS:The phenobarbital group received significantly higher doses of benzodiazepines compared to the benzodiazepine monotherapy group (660 mg vs 340 mg, p < 0.0001). After adjustment, the use of phenobarbital was associated with significantly reduced time to AWS resolution (141.65 h vs 165.72 h, p < 0.0001). However, the use of phenobarbital was associated with the likelihood of mechanical ventilation (19.42 %vs. 0.96 %, p < 0.0001), aspiration pneumonia (22.33 % vs 5.77 %, p = 0.0006), and increased hospital LOS (8 days vs. 6 days, p = 0.0197). In the combination group, earlier phenobarbital initiation (within 24 h) was associated with significantly lower cumulative benzodiazepine dose (530 mg vs 887.50 mg, p = 0.002) and hospital LOS (6 days vs 10 days, p = 0.0017). CONCLUSION AND RELEVANCE/CONCLUSIONS:In our study, patients who received phenobarbital in combination with benzodiazepines had a quicker resolution of AWS but also had a higher incidence of mechanical ventilation, prolonged hospital LOS, and an increased risk of aspiration pneumonia. For patients at high risk of severe alcohol withdrawal, earlier initiation of phenobarbital appeared to yield the most optimal benefit.

Neoadjuvant therapy (NAT) is increasingly being used for pancreatic ductal adenocarcinoma (PDAC). This study investigates how NAT differentially impacts PDAC's carcinoma cells and the tumor microenvironment (TME). Spatial transcriptomics was used to compare gene expression profiles in carcinoma cells and the TME of 23 NAT-treated versus 13 NAT-naïve PDACs. Findings were validated by single-nucleus RNA sequencing (snRNA-seq) analysis. NAT induces apoptosis and inhibits proliferation of carcinoma cells and coordinately upregulates multiple complement genes (C1R, C1S, C3, C4B and C7) within the TME. Higher TME complement expression following NAT is associated with increased immunomodulatory and neurotrophic cancer-associated fibroblasts (CAFs); more CD4⁺ T cells; reduced immune exhaustion gene expression, and improved overall survival. snRNA-seq analysis demonstrates C3 complement is mainly upregulated in CAFs. These findings suggest that local complement dynamics could serve as a novel biomarker for prognosis, evaluating treatment response, and guiding therapeutic strategies in NAT-treated PDAC patients.

BACKGROUND:Cancer-treatment-related cutaneous adverse events (cAEs) are common and may severely impact quality of life (QoL) and decrease treatment outcomes. The Latin American Cutaneous Oncology Management (LACOM) project provides clinical insights into cancer-treatment-related cAEs, offering tools for preventing and managing cAEs. METHODS:LACOM I focuses on integrating education, prophylactic measures, and skincare in cancer treatment to improve treatment adherence, outcomes, and patients' and survivors' QoL. RESULTS:The LACOM panel provides evidence and opinion-based best practice recommendations for oncology skincare programs to support all stakeholders in the Latin American healthcare setting (Argentina, Chili, Colombia, Ecuador, Panama, Peru, and Mexico) working with oncology patients throughout the entire continuum of care to achieve optimal outcomes, improving cancer patients and survivors' QoL. Oncology skincare programs comprise hygiene, moisturization, and sun protection with products that should be safe and help to minimize cAEs and improve skin conditions. CONCLUSIONS:Integrating education, general measures, and skincare programs into cancer treatment should encourage the adoption of a proactive role of skincare from the beginning of treatment and ongoing, supporting optimal outcomes and improving cancer patients' and survivors' QoL.

This comprehensive review examines the effects of various infections on pregnancy, focusing on maternal symptoms, fetal outcomes, diagnostic methods, and placental pathology. The paper covers bacterial, viral, and parasitic infections, their mechanisms of transmission, clinical presentations, and histopathologic findings in the placenta. It emphasizes the importance of early detection and intervention, highlighting the challenges in diagnosis due to often asymptomatic presentations. The review also discusses the placenta's role as a protective barrier and its immune defense mechanisms against pathogens. Overall, this paper serves as a comprehensive resource for understanding the complex interplay between maternal infections, placental pathology, and fetal outcomes.

BACKGROUND:Rhinoplasty is one of the most commonly performed facial surgeries in the USA. There exist many major and minor nasal tip support structures that impact tip projection. Overprojection may result from anatomic factors or may occur iatrogenically during primary rhinoplasty. Achieving reliable, reproducible, and stable results is the aim of nasal tip deprojection rhinoplasty. This technique is designed to decrease nasal tip deprojection in patients with an overly projected nasal tip. METHODS:A retrospective chart review of 2,003 rhinoplasty cases in the senior author's practice was conducted between July 2014 and June 2022. The inclusion criteria were cosmetic or functional rhinoplasty cases with nasal tip deprojection, with a minimum of 12 months of follow-up. Outcomes of interest included the rate of operative revisions and the rate of postoperative infection. RESULTS:447 patients met the inclusion criteria. The mean age of our study group was 32.1 years old, with 409 females. 291 cases were primary rhinoplasties. Mean follow-up period was 22.4 months. Eight patients (1.8%) required empiric antibiotics postoperatively, with 17 patients (3.8%) requiring operative revision. CONCLUSIONS:Our case series demonstrates that combining resection of the medial crura with lateral crural steal and a columellar strut graft allows us to achieve considerable nasal tip deprojection. The comprehensive patient follow-up with a mean of 22.4 months further supports the reliability of our technique.

Placental abruption is a complete or partial separation of the placenta from the uterine decidua. Clinical manifestations include vaginal bleeding, abdominal pain, uterine contractions, and abnormalities in the fetal heart rate tracing. Placental abruption occurs in 0.4% to 1.0% of all pregnancies. However, the pathophysiology remains incompletely understood. We present a review of the pathophysiology, diagnosis, and management of placental abruption, exploring overlapping processes which contribute to premature placental separation. Classic findings and limitations of ultrasound in evaluating placental abruption are explained. Finally, we discuss the management of placental abruption based on gestational age, fetal status, and maternal hemodynamic stability.

INTRODUCTION/BACKGROUND:Despite the well-documented safety of transesophageal echocardiograms (TEEs), inpatient gastroenterology (GI) services are called to clear patients for the procedure when they have GI symptoms or comorbidities ranging from mild to clinically significant. We aimed to assess the clinical utility of such consults in preventing TEE complications. METHODS:We performed a prospective cohort study of all inpatients at our institution who had a TEE ordered from 7/1/2021 through 7/1/2022. Patients' demographic information, indications for TEE, complications from TEE, 30-day readmission rates, GI team recommendations, and results of any GI-related interventions were collected and analyzed. RESULTS:There were 732 patients who had a TEE ordered during our study period, of whom 641 (87.51%) underwent the procedure. Of the 91 (12.49%) who did not have a TEE, none were canceled due to a GI-related concern. There were 23 of 641 patients (3.59%) with complications from the TEE, none of which were GI-related. The GI team was consulted on 36 patients (4.96% of TEEs ordered) and cleared 22 of 36 (61.11%) with no further testing while the remaining 14 of 36 patients (38.89%) underwent workups that were largely normal. Patients who had a GI consult before their TEE had a significantly longer time between their TEE being ordered and the TEE being performed compared with those who did not have a GI consult before their TEE (4.50 days vs 0.77 days, P < 0.01). DISCUSSION/CONCLUSIONS:Inpatient GI team workups to clear patients for a TEE found no contraindications to TEEs, did not change patient care plans, and led to increased hospital costs and lengths of stay.

PURPOSE/OBJECTIVE:To present the short-term outcomes of arthroscopic in situ biceps tenodesis combined with partial rotator cuff repair in patients with massive irreparable rotator cuff tears (MIRCTs) and minimal arthritis. METHODS:A retrospective review was conducted using prospectively maintained institutional databases to identify patients who had undergone a partial rotator cuff repair with in situ biceps tenodesis between March 2017 and December 2022. Patients were included if they (1) were diagnosed pre- or intraoperatively with MIRCT and (2) had complete preoperative and minimum 1-year postoperative patient-reported outcome measures. RESULTS:Thirty-nine patients met the eligibility criteria and were included for analysis. The mean age of the study participants was 65 ± 7 years (range, 46-76) with 76.9% (n = 30) being male. The average follow-up was 21 ± 12 months (range, 12-58). Patients experienced significant improvement in visual analog scale for pain (VAS), American Shoulder and Elbow Surgeons (ASES) score, and subjective assessment numeric evaluation (SANE) score (P < .001 for all comparisons). The pre- to postoperative improvement was 3.1 ± 2.3 for VAS, 27.5 ± 20.6 for ASES, and 31.3 ± 24.8 for SANE. Postoperatively, the average scores for VAS, ASES, and SANE were 1.3 ± 1.5, 79.5 ± 17.0, and 69.6 ± 20.1, respectively. Twenty-six patients (66.7%) achieved the minimal clinically important difference (MCID) for VAS, 33 patients (84.6%) achieved the MCID for ASES, and 30 patients (76.9%) achieved the MCID for SANE. CONCLUSIONS:Partial rotator cuff repair with in situ biceps tenodesis is an effective treatment for MIRCT, leading to significant improvements in patient-reported outcome and range-of-motion measures compared to preoperative conditions. LEVEL OF EVIDENCE/METHODS:Level IV, retrospective case series.

BACKGROUND AND OBJECTIVE/OBJECTIVE:The feasibility and safety of a robotic approach for postchemotherapy retroperitoneal lymph node dissection (PC-RPLND) in testicular cancer have been demonstrated, but data on long-term oncological outcomes of this procedure are limited. Our aim was to evaluate oncological outcomes following robotic PC-RPLND in this setting. METHODS:This retrospective cohort study included consecutive patients with testicular cancer treated with robotic PC-RPLND at 11 academic centers worldwide between 2011 and 2023. Patient characteristics, clinicopathological findings, and oncological outcomes were recorded. Recurrence-free survival (RFS) was estimated via the Kaplan-Meier method. KEY FINDINGS AND LIMITATIONS/UNASSIGNED:A total of 173 patients were included, of whom 159 underwent pure robotic PC-RPLND; 14 cases were converted to open surgery. Among the pure robotic cases, 152 (96%) had nonseminoma, 122 (77%) had International Germ Cell Cancer Collaborative Group good risk, and 120 (76%) had a postchemotherapy mass size ≤5 cm. Salvage chemotherapy was received by ten patients (6%). Median estimated blood loss, operative time, and length of hospital stay were 100 ml, 300 min, and 2 d, respectively. Final pathology revealed necrosis/fibrosis in 64 cases (40%), teratoma in 78 (49%), and viable germ-cell tumor in 17 (11%). At median follow-up of 22 mo (interquartile range 7-50), eight patients had disease recurrence, which was in-field in three cases. One port-site recurrence was identified. The median time to recurrence was 7 mo. The 4-yr RFS rate was 93%. Two cancer-related deaths were recorded. Subgroup analysis revealed that patients with conversion to open surgery were more likely to have a larger preoperative mass and received salvage chemotherapy before RPLND. In addition, conversion to open surgery was associated with a higher rate of perioperative complications; however, oncological outcomes were statistically similar to those for pure robotic PC-RPLND. The main limitation of the study is its retrospective nature. CONCLUSIONS AND CLINICAL IMPLICATIONS/CONCLUSIONS:Robotic PC-RPLND in testicular cancer is associated with acceptable intermediate-term oncological outcomes in appropriately selected patients. PATIENT SUMMARY/RESULTS:In this large multicenter study, we investigated the outcomes of robotic surgery after chemotherapy for advanced testicular cancer. We found that robotic surgery yields acceptable cancer control results.

BACKGROUND:The efficacy of radiofrequency ablation (RFA) in treating thyroid nodules with indeterminate cytology remains less studied. The objective of this study was to determine the efficacy of RFA in treating nodules with Bethesda III that have been molecularly profiled benign (BIII-MPN). METHODS:We included prospectively enrolled patients who underwent RFA for benign and BIII-MPN thyroid nodules. Primary outcome measures were volume reduction ratio (VRR), symptom score (range 0-10), and cosmetic score (range 0-3) at 1, 3, 6, and 12 months after RFA, as well as complication rates. RESULTS:A total of 258 nodules in 192 patients were included (benign: 238 in 174; BIII-MPN: 20 in 18). The median VRR differed insignificantly, whereas symptom and cosmetic score improvements were similar between two cohorts. BIII-MPN thyroid nodules were associated with lower rates of infection and temporary voice change. CONCLUSION/CONCLUSIONS:Our preliminary findings suggest that RFA may be a feasible management option for BIII-MPN thyroid nodules. However, appropriate will be important to address the important risk of potentially missed malignancies.
