Background: Diagnosis of leptomeningeal metastasis (LM) remains challenging due to low sensitivity of CSF cytology and infrequent unequivocal MRI findings. In a previous pilot study, we showed that rare cell capture technology (RCCT) could be used to detect circulating tumor cells (CTC) in the CSF of patients with LM from epithelial tumors. To establish the diagnostic accuracy of CSF-CTC in the diagnosis of LM, we applied this technique in a distinct, larger cohort of patients. Methods: In this institutional review board-approved prospective study, patients with epithelial tumors and clinical suspicion of LM underwent CSF-CTC evaluation and standard MRI and CSF cytology examination...

Physician-scientists are individuals who actively participate in patient care, have undergone additional research training, and devote the majority of their time to research. Physician-scientists are traditionally the primary catalysts in bridging the translational gap-that is, the failure to link fundamental new knowledge in the pathobiology of disease with advances in health care and health policy in a timely manner. However, there has been a shift away from training physician-scientists, and financial support for the physician-scientist is diminishing globally, causing the translational gap to grow...

A 51-year-old female who presented with obstructive jaundice was found to have masses in the pancreatic head and tail as well as suspicious liver and periaortic masses on imaging. Aspiration cytology of the pancreatic tail mass showed abundant large single cells with vacuolated eosinophilic cytoplasm, marked nuclear pleomorphism, large bizarre irregular nuclei, binucleation, and prominent nucleoli. Numerous cells also showed intracytoplasmic black to brown pigmentation. A cell block was obtained and extensive immunohistochemical staining was performed...

BACKGROUND: Studies of social media in both medicine and dentistry have largely focused on the value of social media for marketing to and communicating with patients and for clinical education. There is limited evidence of how dental clinicians contribute to and use social media to disseminate and access information relevant to clinical care. OBJECTIVE: The purpose of this study was to inventory and assess the entry, growth, sources, and content of clinically relevant social media in dentistry...

When are evolutionary outcomes predictable? Cases of convergent evolution can shed light on when, why, and how different species exhibit shared evolutionary trajectories. In particular, studying diverse species in a common environment can illuminate how different factors facilitate or constrain adaptive evolution. Here we integrate studies of pattern and process in the fauna at White Sands (New Mexico) to understand the determinants of convergent evolution. Numerous animal species at White Sands exhibit phenotypic convergence in response to a novel-and shared-selective environment: geologically young gypsum dunes...

OBJECTIVE: Translation of women's mental health research has yet to impact overall prevalence and burden of Mood Disorders in the United States. The lack of standard measures and methodological coordination across studies has contributed to the slow impact of research on outcomes. The primary aims of this project were to demonstrate the process by which multiple investigators, sites, and settings administered a standard women's mental health questionnaire within a new Women's Depression Network...

BACKGROUND: Programmed death 1 (PD-1) inhibition activates partially exhausted cytotoxic T lymphocytes (peCTLs) and induces tumor regression. We previously showed that the peCTL fraction predicts response to anti-PD-1 monotherapy. Here, we sought to correlate peCTL and regulatory T lymphocyte (Treg) levels with response to combination immunotherapy, and with demographic/disease characteristics, in metastatic melanoma patients. METHODS: Pretreatment melanoma samples underwent multiparameter flow cytometric analysis...

Khalid A Mohamedali, Michael G Rosenblum
Angiogenesis is a critical process in numerous diseases, and intervention in neovascularization has therapeutic value in several disease settings, including ocular diseases, arthritis, and in tumor progression and metastatic spread. Various vascular targeting agents have been developed, including those that inhibit growth factor receptor tyrosine kinases, blocking antibodies that interfere with receptor signal transduction, and strategies that trap growth factor ligands. Limited anti-tumor efficacy studies have suggested that the targeted delivery of the human pro-apoptotic molecule Granzyme B to tumor cells has significant potential for cancer treatment...

The persistence of shame-based reactions to child maltreatment (CM) has been associated with poor posttraumatic adjustment. Despite evidence that the postpartum period is a vulnerable time for women with CM histories, little is known about the consequences of maltreatment-specific (MS) shame for postpartum functioning. The current study examined individual differences in MS shame among a sample of women during the postpartum period ( n = 100) as well as prospective relations from MS shame to postpartum psychopathology at 6-, 12-, 15-, and 18-month postpartum...

Foxp3+ CD4+ Regulatory T cells (Tregs) are a subset of immune cells that function to regulate tissue inflammation. Skin is one of the largest organs and is home to a large proportion of the body's Tregs. However, relative to other tissues (such as the spleen and gastrointestinal tract) the function of Tregs in skin is less well defined. Here, we review our understanding of how Tregs migrate to skin and the cellular and molecular pathways required for their maintenance in this tissue. In addition, we outline what is known about the specialized functions of Tregs in skin...

The widespread application of high-throughput sequencing methods is resulting in the identification of a rapidly growing number of novel gene fusions caused by tumour-specific chromosomal rearrangements, whose oncogenic potential remains unknown. Here we describe a strategy that builds upon recent advances in genome editing and combines ex vivo and in vivo chromosomal engineering to rapidly and effectively interrogate the oncogenic potential of genomic rearrangements identified in human brain cancers. We show that one such rearrangement, an microdeletion resulting in a fusion between Brevican (BCAN) and Neurotrophic Receptor Tyrosine Kinase 1 (NTRK1), is a potent oncogenic driver of high-grade gliomas and confers sensitivity to the experimental TRK inhibitor entrectinib...

Parenting group success begins with attendance. Using archival pilot data from 99 mothers who enrolled in the Mom Power (MP) parenting intervention, this study sought to understand the factors that influenced participant engagement and retention. MP is a group-based, early intervention program grounded in attachment theory that utilizes motivational interviewing as a core component to enhance program engagement. Study aims were to qualitatively describe the reasons why mothers were interested in participating in the program, including what they hoped to gain from the experience, and to quantitatively examine the extent to which attendance was associated with demographic, experiential, and psychosocial factors...

Moraxella catarrhalis is an exclusively human respiratory tract pathogen that is a common cause of otitis media in children and respiratory tract infections in adults with chronic obstructive pulmonary disease. A vaccine to prevent these infections would have a major impact in reducing the substantial global morbidity and mortality in these populations. Through a genome mining approach, we identified AfeA, an ∼32 kDa substrate binding protein of an ABC transport system as an excellent candidate vaccine antigen...

BACKGROUND: Recurrence rates for atypical and anaplastic meningiomas range between 9% and 50% after gross total resection and between 36% and 83% after subtotal resection. Optimal treatment of recurrent meningiomas exhibiting atypical/anaplastic histology is complicated because they are often refractory to both surgery and radiation. OBJECTIVE: To evaluate clinical determinants of recurrence and treatment-specific outcomes in patients with recurrent meningiomas exhibiting atypical/anaplastic histology at our institution...

BACKGROUND: Evidence from adult psoriasis studies implicates an imbalance between regulatory and effector T cells, particularly TH-17-producing T cells, in the pathogenesis of psoriasis. Little is known about the immunopathology of psoriasis in children. OBJECTIVE: We sought to functionally characterize the inflammatory cell profiles of psoriatic plaques from pediatric patients and compare them with healthy, age-matched controls and adult psoriasis patients. METHODS: Skin samples from pediatric psoriasis patients and healthy controls were analyzed by multiparameter flow cytometry to determine the dominant immune cell subsets present and cytokines produced...

Bruton tyrosine kinase (BTK) links the B-cell antigen receptor (BCR) and Toll-like receptors with Nuclear factor kappa B (NF-κB). The role of BTK in primary CNS lymphoma (PCNSL) is unknown. We performed a Phase 1 clinical trial with ibrutinib, the first-in-class BTK inhibitor, for patients with relapsed or refractory CNS Lymphoma. Clinical responses to ibrutinib occurred in 10/13 (77%) PCNSL patients, including five complete responses. The only PCNSL with complete ibrutinib resistance harbored a mutation within the coiled-coil domain of Caspase Recruitment Domain Family Member 11, a known ibrutinib resistance mechanism...

OBJECTIVES: Maintaining a restrictive gluten-free diet is the only treatment for celiac disease (CD). Adherence among children and adolescents presents unique challenges and is often inadequate. The International Classification of Functioning, Disability and Health: Children and Youth version (ICF-CY) model encompasses all aspects of human health and daily function while dealing with a disease and interacting with the environment. The purpose was to explore everyday life experiences and challenges as perceived by children and adolescents with CD and their parents in light of the ICF-CY concepts to identify the most crucial components in management challenges...

BACKGROUND: Deficiency of Suppressor of Fused (SuFu), an intracellular mediator of Hedgehog signaling, in the murine mid-hindbrain disrupts cerebellar morphogenesis and cell differentiation in a manner that is rescued by constitutive expression of GLI3 transcriptional repressor (GLI3R). Here, we determined SuFu functions in cerebellar radial precursors following the stage of mid-hindbrain specification using a Blbp-Cre transgene. RESULTS: SuFu-deficient cerebella were severely dysplastic, and characterized by laminar disorganization, and delayed differentiation of ventricular zone-derived precursors...
