RESUMO

Importance: The optimal treatment strategy for patients with human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) of the base of the tongue (BOT) has not been sufficiently studied. Objective: To investigate the rate of and risk factors for occult contralateral nodal disease in patients with HPV-related BOT OPSCC undergoing transoral surgery and bilateral neck dissections. Design, Setting, and Participants: This retrospective case series reviewed the medical records of patients with HPV-related BOT OPSCC who underwent transoral surgery and bilateral neck dissections from January 1, 2002, through December 31, 2018, at the tertiary care center of Washington University School of Medicine in St Louis. Patients had a median follow-up of 30.0 months (interquartile range, 11.0-60.4 months). Patients with recurrent disease or multiple synchronous OPSCC primary tumors were excluded for a total of 89 patients. Data were analyzed from January 1 through June 1, 2019. Main Outcomes and Measures: The primary outcome was the rate of contralateral occult nodal disease. Secondary outcomes were potential risk factors for contralateral occult nodal disease and regional recurrence rates. Results: Eighty-nine patients were included in the series, of whom 81 (91.0%) were men. The mean (SD) age was 60 (9) years. Overall, 34 patients (38.2%) had pathologic contralateral nodal metastases. Seventy patients had no clinical evidence of contralateral nodal disease. Of these 70, occult nodes were identified in 15 (21.4%). Risk of contralateral disease was higher when the primary tumor crossed midline (odds ratio, 6.23; 95% CI, 1.71-22.77). Of the 55 patients with no occult disease identified, only 2 (3.6%) received radiotherapy to the contralateral neck, and no regional recurrence of disease was noted. Conclusions and Relevance: Given the rate of occult contralateral nodal disease of 21.4%, it appears that contralateral elective neck dissection or radiotherapy should be recommended in patients with HPV-related BOT OPSCC. Patients with a pathologically negative result of contralateral neck dissection may not benefit from radiotherapy to that nodal basin. Future prospective investigations should evaluate functional and oncologic outcomes of contralateral elective neck dissection compared with elective radiotherapy in the contralateral neck for HPV-related BOT OPSCC.

RESUMO

INTRODUCTION: Transradial access is increasingly used among neurointerventionalists as an alternative to the transfemoral route. Currently available data, building on the interventional cardiology experience, primarily focus on right radial access. However, there are clinical scenarios when left-sided access may be indicated. The purpose of this study was to evaluate the technical feasibility of left transradial access to cerebral angiography across three institutions. METHODS: A retrospective chart review was performed for patients who underwent cerebral angiography accessed via the left radial artery at three institutions between January 2018 and July 2019. The outcome variables studied were successful catheterization, vascular complications, and fluoroscopic time. RESULTS: Nineteen patients underwent a total of 25 cerebral angiograms via left transradial access for cerebral aneurysms (n=15), basilar occlusion (n=1), carotid stenosis (n=1), arteriovenous malformation (n=1), and cervical neurofibroma (n=1). There were 12 diagnostic angiograms and 13 interventional angiograms. The left transradial approach was chosen due to left vertebrobasilar pathology (n=22), right subclavian stenosis (n=2), and previous right arm amputation (n=1). There was one instance of radial artery spasm, which resolved after catheter removal, and one conversion to transfemoral access in an interventional case due to lack of distal catheter support. There were no procedural complications. CONCLUSIONS: Left transradial access in diagnostic and interventional cerebral angiography is a technically feasible, safe, and an effective alternative when indicated, and may be preferable for situations in which pathology locations or anatomic limitations preclude right-sided radial access.

RESUMO

BACKGROUND: The development of next generation sequencing (NGS) methods led to a rapid rise in the generation of large genomic datasets, but the development of user-friendly tools to analyze and visualize these datasets has not developed at the same pace. This presents a two-fold challenge to biologists; the expertise to select an appropriate data analysis pipeline, and the need for bioinformatics or programming skills to apply this pipeline. The development of graphical user interface (GUI) applications hosted on web-based servers such as Shiny can make complex workflows accessible across operating systems and internet browsers to those without programming knowledge. RESULTS: We have developed GENAVi (Gene Expression Normalization Analysis and Visualization) to provide a user-friendly interface for normalization and differential expression analysis (DEA) of human or mouse feature count level RNA-Seq data. GENAVi is a GUI based tool that combines Bioconductor packages in a format for scientists without bioinformatics expertise. We provide a panel of 20 cell lines commonly used for the study of breast and ovarian cancer within GENAVi as a foundation for users to bring their own data to the application. Users can visualize expression across samples, cluster samples based on gene expression or correlation, calculate and plot the results of principal components analysis, perform DEA and gene set enrichment and produce plots for each of these analyses. To allow scalability for large datasets we have provided local install via three methods. We improve on available tools by offering a range of normalization methods and a simple to use interface that provides clear and complete session reporting and for reproducible analysis. CONCLUSION: The development of tools using a GUI makes them practical and accessible to scientists without bioinformatics expertise, or access to a data analyst with relevant skills. While several GUI based tools are currently available for RNA-Seq analysis we improve on these existing tools. This user-friendly application provides a convenient platform for the normalization, analysis and visualization of gene expression data for scientists without bioinformatics expertise.

RESUMO

BACKGROUND: Spindle cell oncocytomas (SCOs) are rare neuroendocrine tumors of the posterior pituitary that are often misdiagnosed as nonfunctional pituitary tumors. Fewer than 50 cases of SCOs have been described in the literature, and many of these reports have documented the tumors to be hypervascular on imaging or histology. CASE DESCRIPTION: We present the first cerebral angiography imaging findings of an SCO before primary resection. The discovery of a prominent tumor blush, enlarged meningohypophyseal feeders bilaterally, and prominent tumor draining veins aided in preoperative planning and subsequent successful endoscopic transsphenoidal surgical resection. CONCLUSIONS: Despite being a rare entity, SCOs should be included in the differential diagnosis when working up a hypervascular sellar tumor. Flow voids may be present on initial magnetic resonance imaging evaluation. Subsequent digital subtraction angiography can be used to further investigate abnormal vasculature and aid in surgical planning.

RESUMO

BACKGROUND: Techniques for endovascular management of carotid-cavernous fistulas (CCFs) have evolved over the years. Current strategies include transarterial or transvenous approaches and direct puncture or exposure of the cavernous sinus. Rarely, complex CCFs may require multiple approaches or procedures. We describe our experience managing CCFs, reporting on outcomes and technical nuances. METHODS: A retrospective review of institutional records was conducted to identify consecutive cases of CCF treated between July 2005 and July 2016. Pertinent technical details and outcomes were recorded. RESULTS: In 44 patients, 51 procedures were performed. There were 13 direct CCFs and 31 indirect CCFs: 13 (30%) type A, 3 (7%) type B, 5 (11%) type C, and 23 (52%) type D. A transarterial approach was selected in 39% of cases (n = 20), resulting in a long-term successful embolization rate of 60% (n = 12). Transvenous methods via the inferior petrosal sinus or superior ophthalmic vein were used in 49% of cases (n = 25), resulting in a long-term obliteration rate of 88% (n = 22). Multimodal management was required in 5 patients, including 1 patient in whom a craniotomy was performed to facilitate coil embolization of the cavernous sinus under direct vision. A 7% complication rate (n = 3) was observed, with significant morbidity in 1 patient. CONCLUSIONS: CCFs are complex vascular lesions that require facility with various endovascular and surgical approaches. High-flow, direct-type fistulas may harbor a significant risk of recurrence after transarterial embolization. Partial or unsuccessful embolization may necessitate an open surgical approach to the superior ophthalmic vein or cavernous sinus.

RESUMO

INTRODUCTION: Transradial artery access (TRA) for cerebrovascular angiography is increasing due to decreased access site complications and overwhelming patient preference. While interventional cardiologists have reported up to 10 successive TRA procedures via the same radial access site, this is the first study examining successive use of the same artery for repeat procedures in neurointerventional procedures.1 METHODS: We reviewed our prospective institutional database for all patients who underwent a transradial neurointerventional procedure between 2015 and 2019. Index procedures were defined as procedures performed via TRA after which there was a second TRA procedure attempted. Reasons for conversion to a transfemoral approach (TFA) for subsequent procedures were identified. RESULTS: 104 patients underwent 237 procedures (230 TRA, 7 TFA). 97 patients underwent ≥2 TRA procedures, 20 patients >3, four patients >4, three patients >5, and two patients >6 TRA procedures. The success rate was 94.7% (126/133) with 52% (66/126) of successive procedures performed via the same radial access site (snuffbox vs antebrachial) while the alternate radial artery segment was used for access in 48% (60/126) of subsequent procedures. There were seven (5.3%) cases requiring crossover to TFA, six cases for radial artery occlusion (RAO) and one for radial artery narrowing. CONCLUSION: Successive TRA is both technically feasible and safe for neuroendovascular procedures in up to six procedures. The low failure rate (5.3%) was primarily due to RAO. Thus, even without clinical consequences, strategies to minimize RAO should be optimized for patients to continue to benefit from TRA in future procedures.

RESUMO

Significant resource is spent by drug discovery project teams to generate numerous, yet unique target constructs for the multiple platforms used to drive drug discovery programs including: functional assays, biophysical studies, structural biology, and biochemical high throughput screening campaigns. To improve this process, we developed Modular Protein Ligation (MPL), a combinatorial reagent platform utilizing Expressed Protein Ligation to site-specifically label proteins at the C-terminus with a variety of cysteine-lysine dipeptide conjugates. Historically, such proteins have been chemically labeled non-specifically through surface amino acids. To demonstrate the feasibility of this approach, we first applied MPL to proteins of varying size in different target classes using different recombinant protein expression systems, which were then evaluated in several different downstream assays. A key advantage to the implementation of this paradigm is that one construct can generate multiple final products, significantly streamlining the reagent generation for multiple early drug discovery project teams.

RESUMO

BACKGROUND: The calcaneal slide osteotomy is a common procedure used for the surgical correction of heel varus and valgus deformities. A variety of fixation methods exist including screws and plates. The literature shows a high rate of hardware prominence with screws leading to subsequent removal of hardware. Few studies have examined the use of plates for fixation of a calcaneal osteotomy. The purpose of this study was to assess outcomes following fixation of a calcaneal osteotomy with a calcaneal slide plate. METHODS: This is a retrospective consecutive case series of all patients who underwent either a medial or lateral calcaneal slide osteotomy using the specialized calcaneal slide plate between September 2013 and December 2018 by a single surgeon. The primary outcome measures were the rate of hardware removal, healing of the calcaneal osteotomy, and any associated complications such as infection or incision healing delays. Patient baseline demographics and procedure-related data were recorded. The minimum follow-up was 4 months. A total of 81 procedures were performed using this calcaneal slide plate. RESULTS: All of the patients had one or more additional procedures at the same time as the calcaneal osteotomy. All of the calcaneal osteotomies healed without displacement. Only 1 patient (1.2%) returned to the operating room and had removal of the calcaneal slide plate, which was after osteotomy union for an infected wound. There were no cases of hardware failure or removal due to it being symptomatic. CONCLUSION: A specialized calcaneal slide plate was an effective fixation device for both medial and lateral calcaneal slide osteotomies for a variety of foot and ankle conditions. The union rate was 100% and none of the patients had hardware symptoms, which is an improvement on published reports of symptomatic hardware after calcaneal slide osteotomy. LEVEL OF EVIDENCE: Level IV, retrospective case series.

RESUMO

This article extends previous work studying performance characteristics of the population bioequivalence (PBE) statistical test recommended by the US Food and Drug Administration (FDA) for orally inhaled and nasal drug products. Based on analysis of a metered dose inhaler database for impactor sized mass, a simulation study was designed to compare performance of the recommended PBE approach with several modified or alternative approaches. These included an extended PBE that separately modeled within-batch (can) and between-batch (batch) variability and average bioequivalence (ABE) tests that modeled with or without between-batch variability and with or without log-transformation. This work showed that separately modeling within- and between-batch variability while increasing the number of sampled batches addressed previously identified issues of the PBE approach when between-batch variability was present, namely, (a) increased risk for falsely concluding equivalence and (b) low probability of correctly concluding equivalence. The same modifications were also required of the ABE to achieve expected performance. However, these modifications did not successfully address the issue of equivalence conclusions that depended on the direction of product mean differences (asymmetric performance). This work highlights the importance of understanding decision-making error rates in developing regulatory recommendations to standardize bioequivalence outcomes across products.

RESUMO

BACKGROUND: The incidence of human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) is rising, even in elderly patients. The outcomes of transoral surgery (TOS) in this population are not entirely known. METHODS: A retrospective review was performed at two institutions from October 2003 to September 2016 on patients 70 years or older with HPV-related OPSCC treated with TOS. RESULTS: A total of 75 patients were included with a mean age of 74 years (70-87 years). At a median follow-up of 35.7 months, 3-year overall survival was 81.5% and disease-specific survival was 94.3%. Advanced cT stage (odds ratio, 2.74; 95% confidence interval, 1.13-6.64) negatively impacted OS. Conjunctive consolidation was performed to create a staging system with patients older than 80 years, severe comorbidity, and cT3-4 having worse survival. CONCLUSIONS: Elderly patients with HPV-related OPSCC treated with TOS have excellent survival and therefore should not be excluded from such therapy based on age alone.

RESUMO

Endothelial cell (EC) dysfunction is known to contribute to cerebral aneurysm (CA) pathogenesis. Evidence shows that damage or injury to the EC layer is the first event in CA formation. The mechanisms behind EC dysfunction in CA disease are interrelated and include hemodynamic stress, hazardous nitric oxide synthase (NOS) activity, oxidative stress, estrogen imbalance, and endothelial cell-to-cell junction compromise. Abnormal variations in hemodynamic stress incite pathological EC transformation and inflammatory zone formation, ultimately leading to destruction of the vascular wall and aneurysm dilation. Hemodynamic stress activates key molecular pathways that result in the upregulation of chemotactic cytokines and adhesion molecules, leading to inflammatory cell recruitment and infiltration. Concurrently, oxidative stress damages EC-to-EC junction proteins, resulting in interendothelial gap formation. This further promotes leukocyte traffic into the vessel wall and the release of matrix metalloproteinases, which propagates vascular remodeling and breakdown. Abnormal hemodynamic stress and inflammation also trigger adverse changes in NOS activity, altering proper EC mediation of vascular tone and the local inflammatory environment. Additionally, the vasoprotective hormone estrogen modulates gene expression that often suppresses these harmful processes. Crosstalk between these sophisticated pathways contributes to CA initiation, progression, and rupture. This review aims to outline the complex mechanisms of EC dysfunction in CA pathogenesis.

RESUMO

OBJECTIVE: While oesophageal squamous cell carcinoma remains infrequent in Western populations, the incidence of oesophageal adenocarcinoma (EAC) has increased sixfold to eightfold over the past four decades. We aimed to characterise oesophageal cancer-specific and subtypes-specific gene regulation patterns and their upstream transcription factors (TFs). DESIGN: To identify regulatory elements, we profiled fresh-frozen oesophageal normal samples, tumours and cell lines with chromatin immunoprecipitation sequencing (ChIP-Seq). Mathematical modelling was performed to establish (super)-enhancers landscapes and interconnected transcriptional circuitry formed by master TFs. Coregulation and cooperation between master TFs were investigated by ChIP-Seq, circularised chromosome conformation capture sequencing and luciferase assay. Biological functions of candidate factors were evaluated both in vitro and in vivo. RESULTS: We found widespread and pervasive alterations of the (super)-enhancer reservoir in both subtypes of oesophageal cancer, leading to transcriptional activation of a myriad of novel oncogenes and signalling pathways, some of which may be exploited pharmacologically (eg, leukemia inhibitory factor (LIF) pathway). Focusing on EAC, we bioinformatically reconstructed and functionally validated an interconnected circuitry formed by four master TFs-ELF3, KLF5, GATA6 and EHF-which promoted each other's expression by interacting with each super-enhancer. Downstream, these master TFs occupied almost all EAC super-enhancers and cooperatively orchestrated EAC transcriptome. Each TF within the transcriptional circuitry was highly and specifically expressed in EAC and functionally promoted EAC cell proliferation and survival. CONCLUSIONS: By establishing cancer-specific and subtype-specific features of the EAC epigenome, our findings promise to transform understanding of the transcriptional dysregulation and addiction of EAC, while providing molecular clues to develop novel therapeutic modalities against this malignancy.

RESUMO

Introduction: Endobronchial granular cell tumors are uncommon in the pediatric population. Case report: A 9-year-old female presented with respiratory failure due to an endobronchial tumor. After debulking and diagnosis, she underwent thoracotomy with right upper lobe resection and bronchoplasty. Pathology demonstrated an endobronchial S-100 negative granular cell tumor, which to our knowledge, is the first such report in the literature. Conclusion: Endobronchial granular cell tumors may cause obstructive respiratory failure, are amenable to surgery, and may be S-100 negative.

RESUMO

BACKGROUND: Trigeminal neuralgia (TN), hemifacial spasm (HFS), and glossopharyngeal neuralgia (GPN) are hyperactive dysfunction syndromes (HDS) commonly caused by microvascular compression of their root entry zone. Cases of combined HDS involving 2 or more of these entities are extremely rare. Although microvascular decompression is the surgical treatment of choice, there are additional techniques that have been described as efficient methods to accomplish vessel transposition. OBJECTIVE: To our knowledge, we present the first reported case of triple simultaneous HDS successfully treated using the clip-sling technique to achieve microvascular decompression. We discuss several technical pearls and pitfalls relevant to the use of the sling suspension technique. METHODS: We report the rare case of a 66-yr-old male with combined simultaneous unilateral right-sided TN, HFS, and GPN because of a dolichoectatic vertebrobasilar system compressing the exit zones of the right trigeminal, facial, and glossopharyngeal nerves and present a literature review of combined HDS and their different surgical treatments. RESULTS: Symptomatic TN, HFS, and GPN have been reported 8 times in the literature with our case being the ninth. A retrosigmoid craniotomy was performed for microvascular decompression of the brainstem with a clip-sling suspension technique augmented with Teflon felt pledgets. The patient had immediate complete relief from TN, HFS, and GPN postoperatively. CONCLUSION: Microvascular decompression using the clip-sling technique via a retrosigmoid approach should be considered as a safe and effective option for transposition and suspension of the offending artery and decompression of the affected nerve roots in cases of combined HDS.

RESUMO

Cerebral aneurysm rupture is a devastating event resulting in subarachnoid hemorrhage and is associated with significant morbidity and death. Up to 50% of individuals do not survive aneurysm rupture, with the majority of survivors suffering some degree of neurological deficit. Therefore, prior to aneurysm rupture, a large number of diagnosed patients are treated either microsurgically via clipping or endovascularly to prevent aneurysm filling. With the advancement of endovascular surgical techniques and devices, endovascular treatment of cerebral aneurysms is becoming the first-line therapy at many hospitals. Despite this fact, a large number of endovascularly treated patients will have aneurysm recanalization and progression and will require retreatment. The lack of approved pharmacological interventions for cerebral aneurysms and the need for retreatment have led to a growing interest in understanding the molecular, cellular, and physiological determinants of cerebral aneurysm pathogenesis, maturation, and rupture. To this end, the use of animal cerebral aneurysm models has contributed significantly to our current understanding of cerebral aneurysm biology and to the development of and training in endovascular devices. This review summarizes the small and large animal models of cerebral aneurysm that are being used to explore the pathophysiology of cerebral aneurysms, as well as the development of novel endovascular devices for aneurysm treatment.

RESUMO

BACKGROUND: Numerous large randomized trials have shown a significant morbidity and mortality benefit with the transradial approach (TRA) over the transfemoral approach (TFA) for endovascular procedures. However, this technique is routinely avoided or aborted due to unfamiliarity with the technique and the associated anatomical difficulties that may be faced in this approach. The objective of this review is to identify both the common and uncommon challenges that may be encountered during a transradial approach for cerebrovascular catheterization and to provide tips and tricks to overcome the transradial learning curve. METHOD: A careful review of the literature and of all our transradial cases was carried out to identify the common challenges and complications that are encountered when using TRA for diagnostic cerebral angiography and neurointerventions. RESULTS: A stepwise approach is provided to prevent and manage common challenges including radial artery access failure, radial artery spasm, radial artery anomalies and tortuosity, radial artery occlusion, radial artery perforation and hematoma, subclavian tortuosity and anomalies, and catheter knots and kinks. CONCLUSION: The ability to recognize and navigate anatomical variations and complications unique to TRA will accelerate learning, decrease unnecessary morbidity and mortality, and further advance the neurovascular field.

RESUMO

INTRODUCTION AND OBJECTIVES: Opioid use disorder has become increasingly prevalent in recent years. Previous studies have shown that patients with opioid use disorder undergoing orthopedic, elective abdominopelvic, and cardiac procedures have poorer postoperative outcomes. The aim of this study was to examine the effect of pre-existing opioid use disorder on postoperative outcomes including in-hospital mortality, hospital length of stay (LOS), hospital readmission, and postoperative complications in patients undergoing appendectomy or cholecystectomy. METHODS: The authors used administrative data from the State Inpatient Databases of the Healthcare Cost and Utilization Project for the years 2007-2014 from California, Florida, Kentucky, Maryland, and New York. The authors compared unadjusted rates of in-hospital mortality, postoperative complications, LOS, and 30-day and 90-day readmission status. The authors calculated the adjusted odds ratio (OR) for their outcomes using logistic regression models. RESULTS: In all, 488,981 appendectomy patients and 790,491 cholecystectomy patients aged ≥ 18 years were included in the analysis. Appendectomy (OR 2.26) but not cholecystectomy patients with opioid use disorder had statistically significant adjusted odds of in-hospital death. Patients with opioid use disorder (overall reported, and by each procedure separately) had higher adjusted odds of postoperative complication (OR 1.46), 30-day readmission (OR 1.80), 90-day readmission (OR 1.98), and longer LOS (OR 1.37). CONCLUSIONS: The authors found higher unadjusted rates and adjusted ORs of in-patient mortality, hospital readmission, and postoperative complications in patients with opioid use disorder undergoing common abdominal surgeries. The authors' study shows that opioid use disorder is a risk factor for poorer postoperative outcomes in this surgical patient population.

RESUMO

BACKGROUND: Despite high prevalence of nonalcoholic fatty liver disease in China, understanding of the disease appears to be low. AIMS: We assessed the knowledge of NAFLD among the public in Beijing, China, as well as diet and physical activity patterns, which may provide information useful for NAFLD prevention and management. METHODS: We surveyed adult patients and family members in the Peking University Health Science Center (PUHSC) ultrasound clinic and office staff in Beijing, China. Participants provided demographic and medical history data. NAFLD-related knowledge and diet and physical activity were assessed. RESULTS: A total of 1296 participants at the PUHSC clinic (51% female, median age 35, 61% college-educated) and 494 participants in offices (61% female, median age 43, 74% college-educated) completed the survey. Response rate was 68.4% and 96.7%, respectively. In clinic and offices, 44% versus 48% were overweight/obese, 5% had a history of diabetes in both groups, and 14% versus 23% had a personal history of NAFLD. Median knowledge score was 15 out of 25 in clinic versus 16 in offices. 44.9% reported minimal physical activity. Factors associated with higher NAFLD knowledge scores (> 16) on multivariate analysis included college education or higher (OR 1.7, p = 0.01), family history of hyperlipidemia (OR 1.96, p < 0.001), and number of sugary drinks per week (OR 0.74, p = 0.006). No factors were significantly associated with physical activity levels. CONCLUSIONS: Adults in Beijing had low knowledge about NAFLD, and most were not physically active. Programs to increase public awareness of NAFLD and promote physical activity are critical to curb this growing epidemic.
