The Current State of Neoadjuvant Therapy in Resectable Advanced Stage Melanoma.

The advent of effective immunotherapy and targeted therapy has significantly improved outcomes in advanced-stage resectable melanoma. Currently, the mainstay of treatment of malignant melanoma is surgery followed by adjuvant systemic therapies. However, recent studies have shown a potential role for neoadjuvant therapy in the treatment of advanced-stage resectable melanoma.

A qualitative study of how team characteristics and leadership are associated with information sharing in multidisciplinary intensive care units.

Background: Better information sharing in intensive care units has been associated with lower risk-adjusted mortality. This study explored how team characteristics and leadership are associated with information sharing in 4 intensive care units in a single large urban, academic medical center.

Methods: A qualitative study was conducted to understand how team characteristics and leadership are associated with information sharing.

High-Density IgG4+ Plasma Cells Infiltration Is Associated With Fibroplasia in Fibrostenotic Crohn's Disease.

Transmural fibrosis and stricture formation are key pathogenic processes for Crohn's disease that underlies clinical refractoriness, resulting in severe morbidity. The mechanisms for fibroplasia in Crohn's are not fully elucidated. In this study, we identified a cohort of refractory Crohn's disease with surgically resected bowel specimens including cases with bowel stricture and age-/sex-matched refractory disease without bowel stricture.

Clinical and histopathologic characterization of SETD2-mutated colorectal cancer.

With the advent of next-generation sequencing (NGS), identifying and better understanding genetic mutations in cancer pathways has become more feasible. A mutation now commonly reported in NGS panels is the SETD2 gene (H3K36 trimethyltransferase). However, its contributions to colorectal cancer (CRC) are not well described.

Is the Implementation of an Interprofessional Communication Smart Phone Application Associated With Improved Survival Among Critically Ill Surgical Patients?

Introduction: Patients admitted to intensive care units (ICUs) have high rates of mortality and morbidity. Improved communication between providers within ICUs may reduce morbidity. The goal of this study is to leverage a natural experiment of the temporally staggered implementation of a smart phone application for interprofessional communication to quantify the association with postoperative mortality and morbidity among critically ill surgical patients.

Druggable sites/pockets of the p53-DNAJA1 protein-protein interaction: In silico modeling and in vitro/in vivo validation.

Mutation of p53 is the most common genetic alteration in human cancer. The vast majority of p53 mutations found in cancer are missense mutations, with some single nucleotide point mutations leading to the accumulation of mutant p53 protein with potential gain of oncogenic function. The mechanism for stabilization and accumulation of missense mutant p53 protein in malignant cells is not fully understood.

The effect of human immunodeficiency virus and human papillomavirus strain diversity on the progression of anal squamous intraepithelial lesions.

Anal squamous cell carcinoma (SCC) is a human papillomavirus (HPV)-mediated malignancy with increasing incidence. Human immunodeficiency virus (HIV) infection is a significant risk factor for anal SCC; however, it is unknown if HIV infection alters anal lesion progression and HPV strain profile. This study aims to determine whether HIV coinfection is associated with progression of HPV-mediated anal lesions and on their HPV strain diversity.

Single Center Experience with Incidence, Impact and Predictors of Biliary Complications in Donation After Circulatory Death Liver Transplantation.

Utilizing allografts from donors after cardiac death (DCD) has improved organ availability, and DCD livers comprise a growing proportion of transplantations. However, it has been suggested that DCD transplantations have worse outcomes. We aimed to characterize outcomes in a large cohort of DCD transplantations, identify trends in outcomes over time, and identify factors associated with the development of biliary complications.

High-Frequency Oscillations in Tumor-Related Epilepsy.

Introduction: To define the patient characteristics, tumor characteristics, and clinical course of patients with primary brain tumors with high-frequency oscillations (HFOs) recorded on electrocorticography. Furthermore, we evaluated whether the presence of HFOs portends a greater risk of postoperative tumor-related epilepsy and whether the resection of HFO-generating tissue reduces likelihood of postoperative tumor-related epilepsy.

Methods: This was a retrospective study of 35 patients undergoing awake craniotomy for tumor resection, all of whom underwent intraoperative electrocorticography.

The Possible Pathogenic Role of IgG4-Producing Plasmablasts in Stricturing Crohn's Disease.

Background: Crohn's disease (CD) is a condition on the spectrum of inflammatory bowel disease that affects up to 20 people per 100,000 in the US annually, and with incidence increasing. One of the most significant sources of morbidity in CD is the formation of strictures, with resultant intestinal blockage a common indication for hospitalization and surgical intervention in these patients. The pathophysiology of stricture formation is not fully understood.

Clinicopathologic characteristics of FBXW7-mutated colorectal adenocarcinoma and association with aberrant beta-catenin localization.

Oncogenic mutations in the adenomatous polyposis coli (APC)/Wnt signaling pathway are well documented. The FBXW7 gene (F-box and WD repeat domain-containing 7) encodes a member of the ubiquitin-proteasome complex that is more recently described to antagonize the oncogenic Wnt pathway by promoting the degradation of β-catenin encoded by the CTNNB1 gene. The pathologic significance of FBXW7 mutation in colorectal carcinoma (CRC) remains under-reported.

Tumor type, epilepsy burden, and seizure documentation: experiences at a single center neuro-oncology clinic.

Background: Patients with both primary and metastatic brain tumors have significant seizure burden due to their tumor. The management of tumor-related epilepsy (TRE) and optimizing antiepileptic drug (AED) regimens requires collaboration between neurologists and seizure specialists, which is facilitated by seizure documentation in clinic notes. We aim to describe seizure incidence in patients seen in neuro-oncology clinical practice.

Human Immunodeficiency Virus Infection Promotes Human Papillomavirus-Mediated Anal Squamous Carcinogenesis: An Immunologic and Pathobiologic Review.

Background: Anal squamous cell carcinoma (SCC) is a rare gastrointestinal malignancy with rising incidence, both in the United States and internationally. The primary risk factor for anal SCC is human papillomavirus (HPV) infection. However, there is a growing burden of disease in patients with human immunodeficiency virus (HIV) and HPV coinfection, with the incidence of anal SCC significantly increasing in this population.

Efficacy of clobazam as add-on therapy in brain tumor-related epilepsy.

Purpose: Brain tumor-related epilepsy (TRE) is often resistant to currently available antiepileptic medications (AEDs). Clobazam was initially approved as adjunctive AED for patients with Lennox Gastaut syndrome but has been used in TRE, despite limited evidence in this context. This observational study aims to examine the effect of clobazam on seizure frequency on patients who have a primary CNS tumor and continued seizures despite their current AEDs.

Diagnosis of epidermodysplasia verruciformis: Two cases highlighting the role of direct HPV L1 gene sequencing.

Epidermodysplasia verruciformis (EV) is a rare skin disease characterized by the development of multiple flat warts with the potential for malignant transformation. Patients are susceptible to human papillomavirus (HPV) infection that develops in a background of either a genetic or acquired immunodeficiency predisposing patients to infection with specific HPV types that are ubiquitous but generally non-pathogenic in healthy individuals. There is no standard clinical methodology for determining the causative HPV from patients with suspected EV.
