The Centre for Economic Policy Research was established in 1983 as a private educational charity, to promote independent analysis and public discussion of open economies and the relations among them. It is pluralist and non-partisan, bringing economic research to bear on the analysis of medium and long-run policy questions. These organizations do not give prior review to the Centre’s publications, nor do they necessarily endorse the views expressed therein. These Discussion Papers often represent preliminary or incomplete work, circulated to encourage discussion and comment. Citation and use of such a paper should take account of its provisional character. Besides its extraordinary virulence, the 1918-19 epidemic was also unique in that a disproportionate number of its victims were men and women aged 15 to 44, giving the age profile of mortality a distinct ‘W’ shape rather than the customary ‘U’ shape, and leading to extremely high death rates in the prime working ages. Controlling for numerous factors including initial income, density, urbanization, human capital, climate, the sectoral composition of output, geography, and the legacy of slavery, the results indicate a large and robust positive effect of the influenza epidemic on per capita income growth across states during the 1920s. We would also like to thank Laura Bennett and Thomas Sproul for their excellent research assistance. Introduction In his Presidential Address to the Economic History Association, Neal (2000, p. However, the epidemic has been almost completely ignored by economists and economic historians. A comprehensive search of EconLit found only two articles relating to the 1918 influenza epidemic, and the epidemic is not even mentioned in any of the leading economic history textbooks or the Cambridge Economic History of the 3 United States. In addition, the textbooks by Atack and Passell (1994), Walton and Rockoff (2001), and Cain and Hughes (1997) fail to mention the epidemic. The purpose of this paper is to examine the effects of the 1918-1919 influenza epidemic on subsequent economic growth using data from a sample of U. We find that the epidemic is positively correlated with subsequent economic growth in the United States, even after taking into account differences in population density, urbanization, levels of income per capita, climate, geography, the sectoral composition of output, human capital accumulation, and the legacy of slavery. Our results suggest that one more death per thousand resulted in an average annual increase in the rate of growth of real per capita income over the next ten years of at least 0. Below we describe the main features of the epidemic, then turn to the theoretical and empirical evidence regarding the possible links between the epidemic and economic growth. The influenza epidemic swept the world in three waves: the first in the spring of 1918, the second deadly wave in the fall of 1918, and a third wave that further afflicted some regions in early 1919. The precise origin of the epidemic is unknown, but the first recorded outbreak worldwide occurred in March 1918 among army recruits at Camp 5 Funston, Kansas. The virus spread quickly across the United States and reached Europe in a matter of weeks, apparently with the arrival of American troop ships. The influenza epidemic swept across Europe and had reached India, Australia and New Zealand by June 1918 (Patterson and Pyle 1991). The virulence and mortality rate of the first wave of influenza only slightly exceeded normal levels and it therefore attracted little attention. The epidemic was, however, characterized by two traits that clearly linked it to the second deadly wave in the fall, and which distinguished the influenza epidemic from any epidemic before or since: it disproportionately killed young adults, and victims died with excessive accumulation of bloody fluid in their lungs, often with severe complications as a result of pneumonia (Crosby 1989). The authors of this study hypothesize that the virus smoldered for a couple of years before exploding in 1918. Undoubtedly fueled by the troop movements and demobilization surrounding the end of World War I, the virus spread explosively around the world in the second wave, with worldwide mortality from the epidemic peaking in October and November 1918. A third wave affected some areas of the world in early 1919, principally England and Wales, Australia, and other countries in the southern hemisphere. In the United States, the impact of the epidemic varied widely across regions and had a profound demographic impact on the country. In a typical influenza epidemic, the majority of the victims are young children and the elderly, giving the age profile of mortality a distinct ‘U’ shape. A distinguishing characteristic of the 1918 epidemic was that it disproportionately killed men and women ages 15 to 44, so that the age profile of mortality instead followed a ‘W’ pattern. This is illustrated in Figure 2, which plots the age-specific death rates for men and women in the 1918 epidemic and the average rates from 1914 to 1916, along with the same data for whites and nonwhites separately. It is evident from Figure 2 that over one percent of males ages 25 to 34 died as a result of the epidemic. For both whites and nonwhites, the male mortality rate for those ages 15 to 44 exceeded the female mortality rate by 50-75 percent in 1918, in contrast to the non-epidemic years in which the death rates by gender 5 are virtually identical. The death rate for nonwhites also exceeds that of whites, although 6 the ‘W’ pattern characterizes the age-specific death rates of both races. Other than the age, sex, and racial distribution of deaths, little else is known about the pattern of deaths across different subgroups of the population. Some observers argue that there were few differences in mortality rates across income groups (Crosby 1989; Rice 1988), while other evidence suggests that households with higher income levels had 7 lower mortality rates. It does seem clear that the influenza epidemic did not simply kill the weakest members of each cohort. Numerous eyewitness accounts by doctors and other medical personnel attest that influenza killed the most robust individuals in the population. For example, the Acting Surgeon General of the Army remarked that the influenza epidemic “kills the young vigorous, robust adults; ” public health specialists agreed as well that most influenza victims were those who “had been in the best of physical condition and freest from previous disease” (quoted in Crosby 1989, pp. The geographic spread of the influenza epidemic in the United States appears to have been arbitrary, with few regional tendencies in the pattern of influenza mortality across states (Figure 3). The states with the highest death rates from the epidemic – 6 All countries for which age-specific death rates are available also recorded a ‘W’-shaped age distribution of mortality; this is true, for example, in India, Australia, New Zealand, and South Africa (Mills 1986; Rice 1990; Union of South Africa 1921). Since the surveys were conducted after the flu epidemic, it is unclear whether the poverty was a cause or a result of flu mortality within each household. In addition, the categorization of economic status was unclear and certainly not comparable across surveyors or cities. For example, describing the geographic incidence of influenza mortality in Indiana, Ensley (1983, p. Unlike previous epidemics which traveled on a slow east-west axis, the Spanish Lady struck in a sudden, random fashion. Some have conjectured that exposure to the first wave of the influenza virus in the spring of 1918 conferred immunity to the second wave, which may explain some of the regional patterns in influenza mortality, but evidence on this issue is unavailable.

These datasets come from previously Here, we apply our method to laser capture microdissec published studies [39–41, 43, 54]. To identify common gene symbols measured To assess for the presence of batch effects across data across the four platforms, we used the Array Informa sets, we used the procedure recommended by [56]. For gene symbols with of samples using all genes (Additional file 2); and a scat multiple probe sets, we selected the probe with the terplot of samples along the first two principal compo greatest variance within each dataset. In scaled gene expression values in each dataset within each of these analyses, we did not see a strong associ each tissue compartment by subtracting out the popula ation of dataset with sample cluster, providing no strong tion mean expression and dividing by the population evidence of overall batch effects.

A much larger pro stroma, immune) encountered in the normal breast portion of network edges represented epithelial-stromal across a population of patients, and the relative lack of “self-loops” in breast cancer, as compared with normal standardized methods for sampling and handling normal breast. The y-axis indicates the proportion of self-loop relationships among epithelial-stromal crosstalk interactions at progressive levels of statistical significance. For expression network adjacency matrix is able to uncover visualization, we limited the analysis to genes with a net sets of genes that are highly enriched for protein work degree greater than five. The high-level protein interactions and that contribute to important network visualizations suggest several broad differences biological processes in breast cancer. First, the To systematically test for network functional enrich proportion of nodes involved in epithelial-stromal self ment and to directly compare network functional enrich loops (colored pink in. Edge weight indicates the statistical significance of the epithelial-stromal co-expression relationship, edge color indicates the direction of the association (positive is yellow; negative is gray), node size indicates the node’s degree, and node color indicates whether the node was involved in an epithelial-stromal self-loop (pink) or not (gray). The network layout was determined by a force-directed algorithm applied to the network and then by performing hierarchical clustering on the network adjacency matrix and projecting the clustering results onto the network.

Overall, we identified a total of 20, 40, signatures evaluated (Additional files 7 and 8). These data show that epithelial-stromal self nificantly enriched in both the epithelial-epithelial and loop interactions tend to show the largest univariate epithelial-stromal networks. To further evaluate the role of We also identified a subset of pathways that showed epithelial-stromal self-loop nodes in the overall network, significant enrichment in the epithelial-epithelial net we compared the network degree of self-loop genes to works, but not the epithelial-stromal networks. These Interestingly, a signature initially defined by expression data show that self-loop genes tend to be significantly in a fibroblastic neoplasm (the fibromatosis signature more connected in the networks as compared with non [4]) was the most highly enriched signature in the self-loop genes (all p < 2.

In agreement with our was not observed in the positive epithelial-stromal cancer earlier findings, in the McGill University dataset, there cases, in which stromal staining included at least focal was a strong positive association of the proportion of self spindle cell staining in each positive case. Taken together, loop interactions and the statistical significance of network these results support that the emergence of epithelial edges, with an increasing proportion of self-loops among stromal self-loops represents an important property of the the most significant network edges (Additional file 12), rewiring of epithelial-stromal co-expression networks that and we identified significant concordance in predicted occurs in carcinogenesis. The epithelial and stromal expression of each gene is positively correlated in cancer. Stronger protein expression is often seen at the periphery of tumor nests and at the tumor-stroma interface for each protein marker (black bar 100 um, black arrow cancer epithelium; open arrow stromal cells) from the Human Protein Atlas. We wrote a custom R script to per the proportion of pixels stained brown in the epithelium form bulk download of images from the Human Protein and stroma (Additional file 15). Superpixels are ages from a common set of 105 proteins in normal locally smooth regions into which an image can be parti breast (n = 475 images) and breast cancer (n = 672 images) tioned based on local intensity and edge statistics. Superpixels that contained back types, including breast, colorectal, and lymphoma [7, 9, 12]. Specifically, Our analysis of genome-wide epithelial-stromal co the texture features extracted for each superpixel were expression networks showed epithelial-stromal co correlation, contrast, dissimilarity, homogeneity, and local expression network self-loops to be highly enriched binary pattern. A protein epithelial-stromal networks as compared with the normal was classified as co-expressed in the epithelium and breast epithelial-stromal co-expression network. Although a large body of work has supported the with normal breast tissue, with epithelial-stromal protein effectiveness of studying networks of co-expression in co-expression in breast cancer for 45 % of proteins pre teractions to prioritize functionally related genes and dicted by the network analysis to be self-loops and for 38 % biological modules [47, 82–84], it is critical to note that of proteins not predicted to be self-loops, as compared most correlations observed in large scale Omics datasets with only 10 % of proteins in normal samples. Thus, al epithelial-stromal protein co-expression in breast though the analysis of co-expression networks is a useful cancer as compared with normal breast (p < 2. These studies could include a variety of pre-clinical Discussion epithelial-stromal in vitro and in vivo modeling ap Over the past two decades, there has been increasing ap proaches, including 2D and 3D co-culture systems [85] preciation of the importance of epithelial-stromal interac and genetically engineered mouse models. These ap tions in supporting initiation, progression, metastasis, and proaches could be leveraged to determine the biological drug resistance in solid tumors [15, 17, 19, 24]. However, mechanisms producing the patterns of epithelial-stromal little is known on a systems level of how global patterns of co-expression observed in our analyses. These potential epithelial-stromal interactions evolve during carcinogen mechanisms include cancer cell to stromal cell physical esis. Thus, we developed a computational approach for interactions; cancer cell and stromal cell interactions building and analyzing genome-wide epithelial-stromal with the extracellular matrix; and cancer cell and stro co-expression networks using transcriptional profiling mal cell response to secreted factors, such as cytokines, data obtained from matched epithelial and stromal adipokines, proteases, angiogenic factors, growth factors samples. Co-expression networks have been widely used in Additional limitations of the study include the fact that studies of cancer. The stroma con microenvironment from bulk expression profiling data tains a variety of different cell types, including smooth [50]). Further, the critical role of stromal gene expression muscle cells, fibroblasts, endothelial cells, perictyes, and patterns in determining patient prognosis is now well adipocytes. In our bulk stromal tissue analyses, stromal established and has been demonstrated in many cancer expression values represent a summary of expression Oh et al. We performed a large-scale validation experiment of predicted cancer self-loops by evaluating 1147 images from a common set of 105 proteins in normal breast and breast cancer. We then performed machine learning-based epithelial-stromal segmentation followed by quantitation of protein expression in the epithelium and stroma. Pixels whose class was either unknown or which did not belong to either of the classes are represented in black. After this, pixels containing brown stain in each region were extracted by applying a threshold to the intensity values in the red, green, and blue channels of the image. Brown pixels belonging to epithelium or stroma were reported and analyzed for validation. The analysis shows significantly increased epithelial-stromal protein co-expression in breast cancer as compared with normal breast, as predicted by our network analysis (p < 2. There was a trend for increased epithelial-stromal co-expression for predicted self-loops within the cancer samples, although this did not reach statistical significance (45 % vs 38 %, p = 0. Genome Biology (2015) 16:128 Page 16 of 21 from these heterogeneous cell types and our analyses Conclusions were unable to account for differences in stromal cell We developed an approach for constructing and analyz type proportions between samples. In principle, future ing epithelial-stromal co-expression networks in normal studies could address these limitations by applying spatially breast and breast cancer. Our network analysis identi resolved transcriptome profiling methods to enable the fies a major increase in the number of epithelial-stromal assessment of stromal expression patterns with single self-loops in breast cancer samples, and we validated cell resolution [31–34]. Our analysis provides new biological in tome measurements, future work can build on our ana sights into the functional rewiring of epithelial-stromal lysis in several additional directions. The approach is to generate epithelial-stromal co-expression networks may facilitate the development of new diagnostics and from larger sample sizes spanning diverse cancer types. The epithelial-stromal co-expression network analytic frame study included replicate arrays for each sample, which work to enable identification of the genetic and epigenetic were averaged prior to inclusion in our study. This general approach has proven thelial and stromal samples obtained from non to be a powerful method for studying the genetics of gene inflammatory breast carcinomas (30 ductal and 4 lobu expression [88, 89], and we expect integrative analyses lar) and 15 sets of matched epithelial and stromal sam of tissue region-specific genetics and gene expression ples captured from the inflammatory breast carcinoma will provide important insights into the genetic basis of [39], which were profiled using the Affymetrix U133A epithelial-stromal co-expression networks in cancer.

The goal of the initial discussion is to present reassuring to the client and open lines of discussion. Nonverbal Communication Open-end questions often begin with the words ‘‘what’’ or A large part of communication between individuals is nonverbal and ‘‘how’’ and allow the client to talk using their own vocabulary. Frankly addressing issues when nonverbal cues indicate a client ‘‘Are you thinking about euthanasia When a new diagnosis has been made, asking a client what they know about the disease rather than Empathy offering a description of the problem can save time and show the Empathy is the ability to imagine what a client is experiencing and to client that they, and their knowledge, are valued.

A common tell clients they are being heard but also allow them to correct concern is that acknowledging a client’s concerns or state of mind misconceptions. In that sense, reflective-listening comments will escalate that person’s emotions. Experts agree that the opposite operate as a kind of check step in how you perceive the case and usually occurs.

We apply this method to laser capture micro-dissection expression profiling datasets in the setting of breast carcinogenesis. Our analysis shows that epithelial-stromal co-expression networks undergo extensive rewiring during carcinogenesis, with the emergence of distinct network hubs in normal breast, and estrogen receptor-positive and estrogen receptor-negative invasive breast cancer, and the emergence of distinct patterns of functional network enrichment. In contrast to normal breast, the strongest epithelial-stromal co-expression relationships in invasive breast cancer mostly represent self-loops, in which the same gene is co-expressed in epithelial and stromal regions. We validate this observation using an independent laser capture micro-dissection dataset and confirm that self-loop interactions are significantly increased in cancer by performing computational image analysis of epithelial and stromal protein expression using images from the Human Protein Atlas. Conclusions: Epithelial-stromal co-expression network analysis represents a new approach for systems-level analyses of spatially localized transcriptomic data. The analysis provides new biological insights into the rewiring of epithelial-stromal co-expression networks and the emergence of epithelial-stromal co-expression self-loops in breast cancer. The approach may facilitate the development of new diagnostics and therapeutics targeting epithelial-stromal interactions in cancer. Background Communication between the epithelium and stroma is Carcinomas are composed of malignant epithelial cells and mediated through physical interactions between epithelial a complex milieu of stromal cells in the tumor microenvir and stromal cells, through physical interactions of epithe onment (including endothelial cells, fibroblasts, myofibro lial and stromal cells with the intermediating extracellular blasts, smooth muscle cells, adipocytes, and inflammatory matrix, and through the expression of signaling molecules cells) [1, 2]. Stromal expression patterns and morphologic that are relayed between the epithelium and stroma in phenotypes are correlated with disease outcome [3–12], a process known as epithelial-stromal crosstalk [15, 24].

Management of Neck Lesions Pancreas neck adenocarcinomas are especially difcult to manage. Cancers in the pancreas neck are located anterior to the superior mesenteric vessels and portal vein. The precise extent of involvement often cannot be determined prior to surgery; therefore, complex intraoperative decisions are required, and the surgeon must anticipate this.

Pancreatic neck cancer has specific and oncologic characteristics regarding portal vein invasion and lymph node metastasis. Whipple Specimen • Specimen orientation Specimen orientation and inking involves both the pathologist and surgeon as this will help to ensure accurate assessment of the size and extent of the tumor. This margin is often referred to as the “retroperitoneal margin” or “posterior margin, ” but has also been referred to as the “uncinate margin” or “mesenteric margin. Radial rather than en face sections of this margin will more clearly demonstrate how closely this margin is approached by tumor. Radial rather than en face sections of this margin will more clearly demonstrate whether it is involved by tumor. Radial rather than en face sections of this margin will more clearly demonstrate whether it is involved by tumor and also will provide the distance of the tumor from the margin. En face proximal and distal end margins of the vein should be separately submitted as Proximal Portal Vein Margin and Distal Portal Vein Margin. If feasible, this section should be a full 1 thickness of the vein wall demonstrating the depth of tumor invasion, as this has been shown to have prognostic value. The section should be placed into the cassette with the true margin facing down so that the initial section into the block represents the true surgical margin. The section should be removed from the unopened duct and placed into the cassette with the true margin facing down so that the initial section into the block represents the true surgical margin. Other margins analyzed in Whipple specimens include the proximal and distal enteric margins (en face sections) and anterior surface (closest representative). The anterior surface is not a true margin, but identifcation and reporting of this surface when positive may 2-5 portend a risk of local recurrence, and therefore should be reported in all cases. Collectively, these pancreatic tissue surfaces constitute the circumferential transection margin. Designating the various specifc margins with diferent colored inks will allow recognition on microscopy. Some experts in the feld bisect the pancreas along probes placed in the bile and pancreatic ducts and then serially section along each half of the pancreas. Axial slicing provides an overall assessment of the epicenter of the tumor relative to the ampulla, bile duct, duodenum, and pancreas, and all of the pancreatic circumferential tissue margins mentioned above. The most important aspects of dissection are clear and accurate assessment of the margins. A standardized defnition of this would allow better stratifcation of patients into adjuvant regimens following surgical extirpation. Tumor clearance should be reported in millimeters for all margins described above to allow prospective accumulation of these important data for future analysis. Attached organs resected with the specimen en bloc require serial sectioning to assess not only direct extension, but metastatic deposits as well. One section that demonstrates direct invasion of the organ and/or a separate metastatic deposit is required. Distal Pancreatectomy • In left-sided resections the peripancreatic soft tissue margins and the pancreatic neck are assessed. Additionally, involvement of the splenic vessels should be documented and invasion of the spleen is important to determine, as direct tumor invasion constitutes a pT3 pathologic stage. Anterior (cephalad) Peripancreatic (peripheral) Surface: this surface demonstrates the relationship between the tumor and the anterior or cephalad peripancreatic soft tissue and can be representative if grossly positive. Posterior (caudad) Peripancreatic (peripheral) Margin: this margin demonstrates the relationship between the tumor and the posterior or caudad peripancreatic soft tissue and can be representative if grossly positive. Several such sections should be taken closest to the tumor to document absence of involvement; the exact number is dependent on the degree of ambiguity of gross involvement. Protocol for the Examination of Specimens from Patients with Carcinoma of the Exocrine Pancreas. Significance of the depth of portal vein wall invasion after curative resection for pancreatic adenocarcinoma. Minimum dataset for the histopathological reporting of pancreatic, ampulla of Vater and bile duct carcinoma. Important prognostic histological parameters for patients with invasive ductal carcinoma of the pancreas. This includes neoadjuvant therapy (resectable or borderline resectable), adjuvant therapy, and frst-line or subsequent therapy for locally advanced, metastatic, and recurrent disease. Neoadjuvant Therapy (Resectable/Borderline Resectable Disease) • There is limited evidence to recommend specifc neoadjuvant regimens of-study, and practices vary with regard to the use of chemotherapy and radiation. When considering neoadjuvant therapy, consultation at a high-volume center is preferred. If neoadjuvant therapy is recommended, treatment at or coordinated through a high-volume center is preferred, when feasible. For those who received prior neoadjuvant therapy, the adjuvant therapy options are dependent on the response to neoadjuvant therapy and other clinical considerations. Chemoradiation f may improve local control and delay the need for resumption therapy. Gemcitabine alone versus gemcitabine chemotherapy before and after fluorouracil-based chemoradiation following plus radiotherapy in patients with locally advanced pancreatic cancer: an Eastern resection of pancreatic adenocarcinoma. Erlotinib plus gemcitabine compared with 18 Neuzillet C, Hentic O, Rousseau B, et al. Radiation can also be used to palliate pain and bleeding or relieve obstructive symptoms in patients who have progressed or recurred locally. Therefore, the following recommendations are given as examples of commonly utilized regimens. Stents can assist with targeting; however, they can shift and are therefore less reliable than fducials. The simulation scan range should include approximately T4/T5 to L5/S1 (upper abdomen). Patients with a contrast allergy may premedicate with steroids and antihistamines. Some radiation oncologists may prefer to not use oral contrast at simulation and treat with an empty stomach. However, with borderline resectable cases, it may be bowel and stomach dose is warranted. If only one (right and left) is functional, not more than 10% of the kidney is present, not more than 15% of the volume of that volume can receive 18 Gy. Stomach, Max dose 54 Gy; <10% of each organ volume can receive between 50 and 53. Evaluating the impact of a single-day multidisciplinary clinic on the management of pancreatic cancer. The effects of staging laparoscopy on trocar site and peritoneal recurrence of pancreatic cancer.
