BACKGROUND AND OBJECTIVES: In this essay—part memoir, part reflection, and part oral history—I review my early professional development, a several years’ long progression after residency training, during which I grew from functioning as a technically competent primary care doctor to being a capable and compassionate family physician. As part of that development, and with my colleague John Frey, MD, I interviewed several of the founders of the modern family medicine movement. Here I review some of their answers to the fundamental question of my early practice years: What does it mean to be a family physician? I cite some of their words of wisdom, those of particular import for me, and discuss how these words both helped me become a family physician and ring true even today as we approach the 50th anniversary of the founding of family medicine. I conclude by inviting other clinicians and educators in family medicine, those starting out in the field as well as those well on their way, to consider how their personal histories can help inform their involvement in the future of the discipline, especially in light of the ongoing Family Medicine for America’s Health initiative.

In order to integrate the biological, psychological, social, and existential dimensions of care into my day-to-day clinical encounters with patients, I have worked to cultivate several intentions of practice. These intentions of practice—habits of mind that nurture my resolve to attend to patients as complex human beings— help me navigate my interactions with patients and families in ways that are simultaneously efficacious and therapeutic. When routinely recalled and adeptly implemented, they are what distinguish me as a competent and capable practitioner of person-centered care, when I am at my best, from when I am not. I present them here in hopes that others may find them useful as they progress down their ongoing paths as healing physicians. © 2017, Annals of Family Medicine, Inc. All rights reserved.

My personal ethos of healing is an expression of the belief that I can and do act to heal patients while I attend to the traditional goals of medicine. The 7 supporting principles that inform my ethos are dignity, authenticity, integrity, transparency, solidarity, generosity, and resiliency. I invite others, including medical students, residents, and practicing physicians, to reflect and discover their own ethos of healing and the principles that guide their professional growth. A short digital documentary accompanies this essay for use as a reflective prompt to encourage personal and professional development. © 2016, Annals of Family Medicine, Inc. All rights reserved.

Many family physicians have written about how they influence, nurture, and empower people in their communities of practice. In this essay, the author writes of the personal joys that family medicine has brought him. An expression of his appreciation for his work as a family doctor, it touches on 6 themes that continue to rejuvenate his practice: love, faith, mystery, place, dance, and medicine. By examining the emotional and psychological dimensions of these themes, he offers a path by which other family physicians may be able to find sustenance and joy in their daily work.

Professional discussions about communication in medical settings often ignore the various personal identities that doctors and patients bring to their clinical encounters. From my 26 years as a family physician, and informed by literature from other professional disciplines, I propose an alternate understanding: to think of doctors and patients as a collection of individual identities, each formed by a discrete presentation of self. I describe how at least 5 important presentations of self arise in clinical encounters, including those relating to meaning, community, agency, anxiety, and organism. I frame these presentations of self with the mnemonic ABCDE, briefly review key dimensions of each, and suggest how physicians can reflect on these dimensions in order to find equilibrium in their interactions with patients. Lastly, I submit that finding this balance can reduce relational challenges with patients and enhance the therapeutic effectiveness of doctor-patient communication. © Annals of Family Medicine, Inc.

Until 1990, erythropoietin (EPO) was considered to have a single biological purpose and action, the stimulation of red blood cell growth and differentiation. Slowly, scientific and medical opinion evolved, beginning with the discovery of an effect on endothelial cell growth in vitro and the identification of EPO receptors (EPORs) on neuronal cells. We now know that EPO is a pleiotropic growth factor that exhibits an anti-apoptotic action on numerous cells and tissues, including malignant ones. In this article, we present a short discussion of EPO, receptors involved in EPO signal transduction, and their action on non-hematopoietic cells. This is followed by a more detailed presentation of both pre-clinical and clinical data that demonstrate EPO's action on cancer cells, as well as tumor angiogenesis and lymphangiogenesis. Clinical trials with reported adverse effects of chronic erythropoiesis-stimulating agents (ESAs) treatment as well as clinical studies exploring the prognostic significance of EPO and EPOR expression in cancer patients are reviewed. Finally, we address the use of EPO and other ESAs in cancer patients. © 2014 Debeljak, Solár and Sytkowski.

This paper presents a high-sensitivity, all-silica, all-fiber Fabry-Perot strain-sensor. The proposed sensor provides a long active length, arbitrary length of Fabry-Perot cavity, and low intrinsic temperature sensitivity. The sensor was micro-machined from purposely-developed sensor-forming fiber that is etched and directly spliced to the lead-in fiber. This manufacturing process has good potential for cost-effective, highvolume production. Its measurement range of over 3000 με, and strainresolution better than 1 με were demonstrated by the application of a commercial, multimode fiber-based signal processor. © 2011 Optical Society of America.

Cluster validity indices are used to validate results of clustering and to find a set of clusters that best fits natural partitions for given data set. Most of the previous validity indices have been considerably dependent on the number of data objects in clusters, on cluster centroids and on average values. They have a tendency to ignore small clusters and clusters with low density. Two cluster validity indices are proposed for efficient validation of partitions containing clusters that widely differ in sizes and densities. The first proposed index exploits a compactness measure and a separation measure, and the second index is based an overlap measure and a separation measure. The compactness and the overlap measures are calculated from few data objects of a cluster while the separation measure uses all data objects. The compactness measure is calculated only from data objects of a cluster that are far enough away from the cluster centroids, while the overlap measure is calculated from data objects that are enough near to one or more other clusters. A good partition is expected to have low degree of overlap and a larger separation distance and compactness. The maximum value of the ratio of compactness to separation and the minimum value of the ratio of overlap to separation indicate the optimal partition. Testing of both proposed indices on some artificial and three well-known real data sets showed the effectiveness and reliability of the proposed indices. © 2010 Elsevier B.V. All rights reserved.

Purpose:The purpose of this paper isto investigate the internationalisation ofenterprises by specific forms of foreign direct investments (FDI) and international technical cooperation in the defence sector. Design/methodology/ approach: The effects of defence FDI and international technical cooperation activities on the Slovenian economy are investigated using the input-output modelling approach. Findings: The author finds important direct and indirect effects on the Slovenian economy from the FDI and international technical cooperation inflows into enterprises. These positive effects are directly and indirectly linked to enterprises in different statistically classified industrial activities by predominance of the civil sector, which is important for the development of defence and civilian high-technological base products in different regional parts of Slovenia. Originality/value: The presented findings can be used to arrange industrial and regional development strategy and policy measures aimed at accelerating the internationalisation of enterprises and different industrial activities. © Emerald Group Publishing Limited.

Introduction: In patients with ulnar neuropathy at the elbow (UNE), short-segment nerve conduction studies (NCS) are rarely performed due to unclear reference values. We excluded controls with subclinical UNE, calculated normative values, and tested them in UNE patients. Methods: Clinical examination, ultrasonography (US), and 2-cm short-segment ulnar motor NCS across the elbow were performed in 49 controls and 67 UNE patients. In controls, subclinical UNE was diagnosed if at least 2 studies were outside the reference limits in the same 2-cm segment. Results: Exclusion of controls with subclinical UNE produced less stringent normative values (2-cm conduction velocity: 25 to 31 m/s; US cross-sectional area: 11.6 to 9.6 mm2), which raised diagnostic sensitivity (short-segment NCS: 76% to 90%; 10-cm NCS: 72% to 85%, US: 43% to 79%). Conclusions: We propose the use of our normative values in patients with clinically definite and probable UNE after exclusion of alternative diagnoses. © 2014 Wiley Periodicals, Inc.
