David Bryant, Aaron Johnson
The Company of Biologists held the workshop 'Intercellular interactions in context: towards a mechanistic understanding of cells in organs' at historic Wiston House in West Sussex, UK, 5-8 February 2017. The meeting brought together around 30 scientists from disparate backgrounds - yet with a common interest of how tissue morphogenesis occurs and its dysregulation leads to pathologies - to intensively discuss their latest research, the current state of the field, as well as any challenges for the future. This report summarises the concepts and challenges that arose as key questions for the fields of cell, cancer and developmental biology...

This article describes a 3D microfluidic paper-based analytical device that can be used to conduct an enzyme-linked immunosorbent assay (ELISA). The device comprises two parts: a sliding strip (which contains the active sensing area) and a structure surrounding the sliding strip (which holds stored reagents-buffers, antibodies, and enzymatic substrate-and distributes fluid). Running an ELISA involves adding sample (e.g. blood) and water, moving the sliding strip at scheduled times, and analyzing the resulting color in the sensing area visually or using a flatbed scanner...

PURPOSE: The purposes of the study were to evaluate and characterize the cavotricuspid isthmus using multipoint high density voltage gradient mapping (HD-VGM) to see if this would improve on current ablation techniques compared to standard cavotricuspid isthmus ablation techniques. METHODS: Group 1, 25 patients who underwent ablation using standard methods of 3D mapping and ablation, was compared to group 2, 33 patients undergoing ablation using HD-VGM and ablation...

BACKGROUND: Nutrition management of pediatric intestinal failure (IF) requires interdisciplinary coordination of parenteral nutrition (PN) and enteral nutrition (EN) support. Nutrition strategies used by specialists in pediatric intestinal rehabilitation to promote gut adaptation and manage complications have not been previously summarized. METHODS: A practice survey was distributed to members of the dietitian subgroup of the American Society for Parenteral and Enteral Nutrition Pediatric Intestinal Failure Section...

BACKGROUND: Arthroscopic labral base repair (LBR) in the hip is a previously described technique designed to restore the native functional anatomy of the labrum by reproducing its seal against the femoral head. LBR has been shown to have good short-term outcomes. Hypothesis/Purpose: The purpose was to evaluate clinical outcomes of an LBR cohort with a minimum 5-year follow-up. It was hypothesized that patients who underwent LBR would continue to have significant improvement from their preoperative scores and maintain scores similar to their 2-year outcomes...

Greater than 50% of estrogen receptor (ER)-positive breast cancers co-express the progesterone receptor (PR), which can directly and globally modify ER action to attenuate tumor growth. However, whether this attenuation is mediated only through PR-ER interaction remains unknown. To address this question, we assessed tumor growth in ER/PR-positive PDX models of breast cancer where both natural and synthetic progestins were found to antagonize the mitogenic effects of estrogens. Probing the genome-wide mechanisms by which this occurs, we documented that chronic progestin treatment blunted ER-mediated gene expression up to 2-fold at the level of mRNA transcripts...

BACKGROUND: The optimal initial noninvasive diagnostic testing strategy for stable coronary artery disease (CAD) is unknown. Although American guidelines recommend an exercise stress test as the first-line test, European guidelines suggest that stress imaging (myocardial perfusion imaging or stress echocardiography) or coronary computed tomography angiography may be preferable. Understanding the relationship between the initial strategy and downstream yield of obstructive CAD and major adverse cardiac events may provide insight as to the optimal strategy...

INTRODUCTION: Observational evidence suggests physiological benefits and lower mortality with lower chloride solutions; however, 0.9% saline remains the most widely used fluid worldwide. Given uncertainty regarding the association of lower chloride on mortality, it is unlikely that practice will change without direct randomised clinical trial (RCT) evidence. This pilot RCT will investigate the feasibility of a large-scale trial directly comparing low chloride with high chloride fluids in patients with septic shock...

BACKGROUND: Studies examining psychosocial and depression assessment programs in maternity settings have not adequately considered the context in which psychosocial assessment occurs or how broader components of integrated care, including clinician decision-making aids, may optimise program delivery and its cost-effectiveness. There is also limited evidence relating to the diagnostic accuracy of symptom-based screening measures used in this context. The Perinatal Integrated Psychosocial Assessment (PIPA) Project was developed to address these knowledge gaps...

Trophic cascades occur in many ecosystems, but the factors regulating them are still elusive. We suggest that an overlooked factor is that trophic interactions (TIs) are often scale-dependent and possibly interact across spatial scales. To explore the role of spatial scale for trophic cascades, and particularly the occurrence of cross-scale interactions (CSIs), we collected and analysed food-web data from 139 stations across 32 bays in the Baltic Sea. We found evidence of a four-level trophic cascade linking TIs across two spatial scales: at bay scale, piscivores (perch and pike) controlled mesopredators (three-spined stickleback), which in turn negatively affected epifaunal grazers...

Jeremy Goldbogen is an Assistant Professor at the Hopkins Marine Station, Stanford University, USA, where he studies the integrative biology of vertebrate filter feeders from forage fish to baleen whales. He received his Bachelor's degree in Zoology from the University of Texas, Austin, USA, before moving to the Scripps Institution of Oceanography and then the University of British Columbia for his PhD, which he completed in 2010 in the laboratory of Bob Shadwick. After a short postdoc at Scripps, Goldbogen moved to continue his postdoc training at the Cascadia Research Collective in Olympia, Washington...

PURPOSE OF REVIEW: Cardiometabolic diseases increasingly afflict our aging, dysmetabolic population. Complex signals regulating low-density lipoprotein receptor-related protein (LRP) and frizzled protein family members - the plasma membrane receptors for the cadre of Wnt polypeptide morphogens - contribute to the control of cardiovascular homeostasis. RECENT FINDINGS: Both canonical (β-catenin-dependent) and noncanonical (β-catenin-independent) Wnt signaling programs control vascular smooth muscle (VSM) cell phenotypic modulation in cardiometabolic disease...

Myelodysplastic syndromes and chronic myelomonocytic leukemia are blood disorders characterized by ineffective hematopoiesis and progressive marrow failure that can transform into acute leukemia. The DNA methyltransferase inhibitor 5-azacytidine (AZA) is the most effective pharmacological option, but only ∼50% of patients respond. A response only manifests after many months of treatment and is transient. The reasons underlying AZA resistance are unknown, and few alternatives exist for non-responders. Here, we show that AZA responders have more hematopoietic progenitor cells (HPCs) in the cell cycle...

BACKGROUND: Canine papillomaviruses can affect the mucous membranes and skin of young, old and immunocompromised dogs. Most lesions regress spontaneously over a four to eight week interval; however, in some cases the lesions may persist or progress. Cryotherapy is used as a treatment for papillomavirus induced lesions in veterinary practice but there is limited published evidence regarding its use. OBJECTIVES: To describe the history, lesions and treatment outcomes of three dogs with persistent viral papillomas treated with cryotherapy...

BACKGROUND: The patient-centered medical home (PCMH) shows promise for improving care and reducing costs. We sought to reduce the uncertainty regarding the time and cost of PCMH transformation by quantifying the direct costs of transforming 57 practices in a medical group to National Committee for Quality Assurance (NCQA)-recognized Level III PCMHs. METHODS: We conducted structured interviews with corporate leaders, and with physicians, practice administrators, and office managers from a representative sample of practices regarding time spent on PCMH transformation and NCQA application, and related purchases...
