Terminal Ileum Lipoma Causing Ileocolic Intussusception: A Case Report and Literature Review.

Adult intussusception is much rarer than pediatric intussusception and usually occurs secondary to a pathological lead point, most frequently neoplasm. Terminal ileum lipomas are an infrequent cause of adult ileocolic intussusception but can be seen together with the intussusception on initial imaging evaluation, which can guide appropriate diagnosis and management. We describe a case of a 42-year-old man presenting with 12 hours of severe right lower quadrant pain.

Prolonged Ischemia Increases Complications Among High- and Low-Volume Centers in Lung Transplantation.

Background: The effect of prolonged allograft ischemic time on lung transplant outcomes remains controversial, with most studies associating it with increased mortality, but this effect is partly mitigated by center volume. This study sought to evaluate the mechanism of these findings and clarify the impact of ischemic time on short-term outcomes in a national sample.

Methods: Data on lung transplants (January 2010-Janary 2017) were extracted from the Scientific Registry of Transplant Recipients database.

Cardiac tamponade after robotic hiatal hernia repair from liver sling stitch: Case report of a rare complication and literature review.

Introduction And Importance: Cardiac tamponade following hiatal hernia repair is a rare and potentially fatal complication most often associated with the use of mechanical fixation devices for hiatal mesh reinforcement. Only three cases have been reported with sutures alone, and none following robotic hiatal surgery.

Case Presentation: A 54-year-old patient underwent elective robotic hiatal hernia repair with Toupet fundoplication during which a sling suture was placed to elevate the left lateral segment of liver.

Assessing donor organ quality according to recipient characteristics in lung transplantation.

Objective: There is a shortage of donor lungs relative to need, but overall donor organ utilization remains low. The most common reason for refusal is organ quality, but the standards applied to selection vary. In this study we sought to characterize differences in lung utilization according to quality across several clinically distinct recipient pools.

Immune Microenvironment and Genetics in Malignant Pleural Mesothelioma.

Malignant pleural mesothelioma (MPM) is a rare and aggressive malignancy with limited therapeutic options beyond surgery and cytotoxic chemotherapy. The success of immune checkpoint inhibition has been found to correlate with expression of immune-related genes such as (PD-L1) in lung and other solid cancers. However, only a small subset of MPM patients respond to checkpoint inhibition, and this response has been varied and unpredictable across several clinical trials.

Association of Expression with Female Survival Advantage in Malignant Pleural Mesothelioma.

Sex differences in incidence, prognosis, and treatment response have been described for many cancers. In malignant pleural mesothelioma (MPM), a lethal disease associated with asbestos exposure, men outnumber women 4 to 1, but women consistently live longer than men following surgery-based therapy. This study investigated whether tumor expression of genes associated with estrogen signaling could potentially explain observed survival differences.

The Molecular Basis of Malignant Pleural Mesothelioma.

Malignant pleural mesothelioma (MPM) is a rare, aggressive malignancy of the pleural lining associated with asbestos exposure in greater than 80% of cases. It is characterized by molecular heterogeneity both between patients and within individual tumors. Next-generation sequencing technology and novel computational techniques have resulted in a greater understanding of the epigenetic, genetic, and transcriptomic hallmarks of MPM.

The Pancreatic Cancer Microbiome Promotes Oncogenesis by Induction of Innate and Adaptive Immune Suppression.

We found that the cancerous pancreas harbors a markedly more abundant microbiome compared with normal pancreas in both mice and humans, and select bacteria are differentially increased in the tumorous pancreas compared with gut. Ablation of the microbiome protects against preinvasive and invasive pancreatic ductal adenocarcinoma (PDA), whereas transfer of bacteria from PDA-bearing hosts, but not controls, reverses tumor protection. Bacterial ablation was associated with immunogenic reprogramming of the PDA tumor microenvironment, including a reduction in myeloid-derived suppressor cells and an increase in M1 macrophage differentiation, promoting TH1 differentiation of CD4 T cells and CD8 T-cell activation.

A 15-Year-Old with Aphasia and Right Hemiparesis.

Takayasu arteritis (TA) is the third most common vasculitis in childhood, peaking in the second to third decades of life but affecting patients as young as 6 months of age. It often presents with nonspecific systemic symptoms, although at late stages, it may present with cardiac, renal, or focal neurologic sequelae of vascular compromise. In this case, we describe a 15-year-old patient who presented acutely with stroke.

NLRP3 signaling drives macrophage-induced adaptive immune suppression in pancreatic carcinoma.

The tumor microenvironment (TME) in pancreatic ductal adenocarcinoma (PDA) is characterized by immune tolerance, which enables disease to progress unabated by adaptive immunity. However, the drivers of this tolerogenic program are incompletely defined. In this study, we found that NLRP3 promotes expansion of immune-suppressive macrophages in PDA.
