BACKGROUND: Age, family history and ancestry are the only recognized risk factors for prostate cancer (PCa) but a role for environmental factors is suspected. Due to the lack of knowledge on the etiological factors for PCa, studies that are both hypothesis-generating and confirmatory are still needed. This study explores relationships between employment, by occupation and industry, and PCa risk. METHODS: Cases were 1937 men aged ≤75 years with incident PCa diagnosed across Montreal French hospitals in 2005-2009...

INTRODUCTION: Education and research are two major functions of universities, which require proper and systematic exploitation of available knowledge and information. Therefore, it is necessary to investigate the knowledge management status in an education system by considering the function of faculty members in creation and dissemination of knowledge. This study was conducted to investigate the knowledge management status among faculty members of the Kerman University of Medical Sciences based on the Nonaka and Takeuchi models in 2015...

Nursing scientists have long been interested in complex, context-dependent questions addressing individual- and population-level challenges in health and illness. These critical questions require multilevel data (e.g., genetic, physiologic, biologic, behavioral, affective, and social). Advances in data-gathering methods have resulted in the collection of large sets of complex, multifaceted, and often non-comparable data. Scientific visualization is a powerful methodological tool for facilitating understanding of these multidimensional data sets...

Fossils are crucial pieces of evidence that illuminate the past. In the case of paleoanthropology, the discipline that studies human evolution, fossils are tangible objects that shape the ways we understand ourselves and our history. But how, exactly, do fossils find their way into these narratives, and into scientific journals and museums? How do they become pieces of evidence? The Forbes skull reveals a fossil that struggled to become a noteworthy piece of evidence. It was twice lost, first in a library cabinet on the Rock of Gibraltar, and later, in a London museum storeroom...

A number of chronic disease conditions tend to cluster in families with an increased risk in first-degree relatives, but also an increased risk in second-degree relatives. This fact is most often referred to as the heritability (heredity) of these diseases and explained by the influence of genetic factors, or shared environment, even if the more specific details or mechanism leading to disease are not known. New methods have to be explored in screening studies and register linkage studies to define and measure consequences of a positive family history of disease...

Big data indicates the large and ever-increasing volumes of data adhere to the following 4Vs: volume (ever-increasing amount), velocity (quickly generated), variety (many different types), veracity (from trustable sources). The last decade has seen huge advances in the amount of data we routinely generate and collect in pretty much everything we do, as well as our ability to use technology to analyze and understand it. The routine operation of modern health care systems also produces an abundance of electronically stored data on an ongoing basis as a byproduct of clinical practice...

With recommendations from national nursing associations and accrediting bodies to transition to an all baccalaureate prepared nurse workforce by 2020, it is important to understand the expertise that a baccalaureate degreed nurse brings to patient care. The purpose of this article is to establish the differences of a non-bachelor of science in nursing (BSN) registered nurse and a 4-year prepared nurse, as well as to identify the education and clinical trends in critical care that require a BSN-prepared nurse...

The concept of bacteriophage multiplicity of infection (MOI) - ratios of phages to bacteria - historically has been less easily applied than many phage workers would prefer or, perhaps, may be aware. Here, toward clarification of the concept, I discuss multiplicity of infection in terms of semantics, history, mathematics, pharmacology, and actual practice. For phage therapy and other biocontrol purposes it is desirable, especially, not to solely employ MOI to describe what phage quantities have been applied during dosing...

Users of food pantries often have a long history of food insecurity and may be vulnerable to nutritional deficiencies. The quality of their diets is not well researched. The purpose of this systematic review was to summarize the published evidence about the dietary quality of food pantry users. Systematic database searches of PubMed, PsycINFO, PsycARTICLES, and Psychology Behavioral Sciences Collection, and hand searches of references were conducted to identify cross-sectional, cohort, and intervention studies reporting baseline data, conducted in high-income countries and published between 1980 and 2015, which reported on the nutritional adequacy of individuals who have used a food pantry at least once in the previous 12 months...

: Patient history and physical examination are frequently used procedures to diagnose chronic low back pain (CLBP) originating from the facet joints, although the diagnostic accuracy is controversial. The aim of this systematic review is to determine the diagnostic accuracy of patient history and/or physical examination to identify CLBP originating from the facet joints using diagnostic blocks as reference standard. We searched MEDLINE, EMBASE, CINAHL, Web of Science and the Cochrane Collaboration database from inception until June 2016...

As climate change moves insect systems into uncharted territory, more knowledge about insect dynamics and the factors that drive them could enable us to better manage and conserve insect communities. Climate change may also require us to revisit insect management goals and strategies and lead to a new kind of scientific engagement in management decision-making. Here we make five key points about the role of insect science in aiding and crafting management decisions, and we illustrate those points with the monarch butterfly and the Karner blue butterfly, two species undergoing considerable change and facing new management dilemmas...

Medical science is just now realizing the full importance of the microbial world. Thanks to developments such as low-cost high-throughput sequencing of microbial communities comprising the human microbiome, the identity and function of unculturable microbes are being unveiled. Public health officials and neuroepidemiology researchers will be called on to guide the understanding of I-Cubed illnesses and the implications of the human microbiome for communicable and noncommunicable diseases, as the natural history is appreciated and the responsiveness of given medical and neurologic disorders to a variety of medical approaches, including strong antibiotics and immune-modulatory therapy is established...

The Sierra de Atapuerca in northern Spain is ranked among the most important excavation sites in human origins research worldwide. The project boasts not only spectacular hominid fossils, among them the 'oldest European', but also a fully fledged 'popularization industry'. This article interprets this multimedia industry as a generator of different narratives about the researchers as well as about the prehistoric hominids of Atapuerca. It focuses on the popular works of the three co-directors of the project...

Since the nineteenth century, hominid palaeontology has offered critical information about prehistoric humans and evidence for human evolution. Human fossils discovered at a time when there was growing agreement that humans existed during the Ice Age became especially significant but also controversial. This paper argues that the techniques used to study human fossils from the 1850s to the 1870s and the way that these specimens were interpreted owed much to the anthropological examination of Stone, Bronze, and Iron Age skeletons retrieved by archaeologists from prehistoric tombs throughout Europe...

Adjuvants are included in sub-unit or recombinant vaccines to enhance the potency of poorly immunogenic antigens. Adjuvant discovery is as complex as it is a multidiscplinary intersection of formulation science, immunology, toxicology, and biology. Adjuvants such as alum, which have been in use for the past 90 years, have illustrated that adjuvant research is a methodical process. As science advances, new analytical tools are developed which allows us to delve deeper into the various mechanisms that generates a potent immune response...

One Health is a collaborative, transdisciplinary effort working locally, nationally, and globally to improve health for people, animals, plants, and the environment. The term is relatively new (from ∼2003), and it is increasingly common to see One Health included by name in interinstitutional research partnerships, conferences, communications, and organizational frameworks, particularly those championed by the human health and veterinary medical communities. Environmental quality is arguably the least developed component within the One Health framework, but can be guided by expertise within the Society of Environmental Toxicology and Chemistry (SETAC)...
