Infectious diseases are potential catalysts for exploring 'engaged citizen' or socioscientific themes given their interwoven economic, political, scientific and social dimensions. This article describes how an undergraduate course on the history of infectious diseases was modified to explore the impact of two 'engaged citizen' themes (poverty and technology), and to consider the ramifications of those themes on past, present and future infectious disease outbreaks. Four outbreaks were used as the foundation for the course: plague (1350s), puerperal fever (1840s), cholera (1850s) and syphilis (1930s). The first part of the article describes the general course structure and the role of university-wide 'engaged citizen' themes in its semester-specific construction. The second part of the article demonstrates how poverty and technology 'threads' were explored in each of the four historical contexts, and subsequently how they were considered in current and future contexts; appendices with lesson suggestions are provided. The third and final part of the article discusses how this specific model might be more broadly applied to other microbiology instructional contexts. © FEMS 2016. All rights reserved.

Diet, lifestyle modification, and pharmacotherapy with metformin are appropriate initial treatments for many patients with type 2 diabetes (T2DM). However, most individuals do not maintain glycemic control with metformin alone. Addition of other oral antidiabetes drugs (OADs), including sulfonylurea, meglitinide, or thiazolidinedione, is often the next step. Newer options, including incretin-based glucagon-like peptide-1 (GLP-1) receptor agonists (RAs) and dipeptidyl peptidase-4 (DPP-4) inhibitors, offer important benefits as monotherapies or in combination with OADs, with low risk for hypoglycemia. Reductions in glycated hemoglobin (A1C) have been reported among patients treated with GLP-1 RAs (exenatide,-0.8 to-1.1%; liraglutide,-0.8 to-1.6%), as has weight loss (exenatide,-1.6 to-3.1 kg; liraglutide,-1.6 to-3.2 kg). GLP-1 RAs also stimulate β-cell responses and have positive effects on cardiovascular risk factors often present in patients with T2DM. The most common adverse events associated with GLP-1 RAs are nausea, which diminishes over time, and hypoglycemia (when used in combination with a sulfonylurea). A large number of trials demonstrated benefits of GLP-1 RAs, suggesting they could provide suitable treatment options for patients with T2DM. © 2012 Informa UK, Ltd.

Calcaneal fractures represent 2% of all fractures and account for approximately 60% of all tarsal injuries. Motor vehicle collisions and falls are the major causes of these large force compression injuries, causing widening of the heel, loss of heel height, and articular surface displacement. A correlation has been shown between restoration of normal anatomy and satisfactory functional outcome. Once the basic principles of calcaneal fractures are understood, including the anatomy, the radiographic findings, and the challenges that these complicated fractures present, the physician can then be ready with the armamentarium that allows for a patient-specific and injury-specific plan.

The Journal of foot and ankle surgery : official publication of the American College of Foot and Ankle Surgeons | Year: 2010
Compared with traditional open arthrodesis, arthroscopic ankle arthrodesis has been associated with similar rates of fusion, decreased time to union, decreased pain, shorter hospital stay, earlier mobilization, reliable clinical results, and fewer complications. The aim of this case-control study was to analyze cost differences between outpatient arthroscopic and inpatient open ankle arthrodesis. To this end, the authors analyzed 20 ankle arthrodesis procedures: 10 performed by one surgeon on an inpatient basis using an open approach, and 10 performed by another surgeon on an outpatient basis arthroscopically. Patient age, body mass index, tourniquet time, length of stay, complications, days to clinical union, and insurance type, as well as charges and reimbursements for the surgeons and the hospital or surgery center were abstracted from the records. Statistically significant differences were observed between the outpatient arthroscopic and inpatient open arthrodesis groups for total site charges ($3898 +/- 0.00 versus $32,683 +/- $12,762, respectively, P < .0001), reimbursement to the surgeon ($1567 +/- $320 versus $1107 +/- $278, respectively, P = .003), and reimbursement to the hospital or ambulatory surgery center ($1110 +/- $287 versus $8432 +/- $2626, respectively); the ratio of hospital/surgery center charges to hospital/surgery center reimbursements was 28.48% for the inpatient arthroscopic group and 25.80% for the inpatient open arthrodesis group. Outpatient arthroscopic ankle arthrodesis, compared with inpatient open ankle arthrodesis, appears to be less expensive for third party payers, and surgeons are paid more, whereas hospitals and ambulatory surgical centers get paid a greater proportion of the charges that they bill.

The end of the ice age (about 11,000 years ago) was a time of radical change in North America. Many species of large mammals went extinct, along with their habitats. Climate played a major role in this extinction event and current climate change continues to affect and alter the world today. This project will analyze ancient DNA from ice age animals from Natural Trap Cave, Wyoming to examine how these past climate changes relate to genetic variability and extinction. This research will lead to a better overall understanding of how climate change is related to population structure, changes in genetic variation, and ultimately extinction, which may have potential effects on how biologists think about and mitigate the current human-caused climate change occurring today. This project will also provide many opportunities for scientific engagement and outreach to both the general public and in classroom settings. The intriguing nature of the excavations and ultimate findings make this expedition a perfect opportunity to bring science to the general public through print and television media. Additionally, this is an excellent opportunity to give high school students real time experience on how field science is performed. Via remote participation on the web, this project will give students the opportunity to participate in the experience of what it is like to excavate a fossil site, live out in the field, and unearth bones of gigantic, long-dead beasts, but in a safe, virtual setting.
The end-Pleistocene was a time of radical change in North America. Many species of large mammals went extinct, along with the loss of a variety of associated ecosystems. Climate played a major role in this extinction event and current climate change continues to affect and alter ecosystems today. This project will re-open Natural Trap Cave in northern Wyoming to investigate paleoecological responses to climate change and how this relates to the megafaunal extinction events at the end of the Pleistocene. The permanently cold and moist conditions at NTC have preserved a large collection of megafaunal bones which still contain ancient DNA (aDNA) and collagen molecules. This rare resource is optimal to perform population-level analyses of genetic variation in the critical phases before, during, and after the end-Pleistocene extinction events. Key questions investigated in this project include: 1) Was the Pleistocene extinction event preceded by, or concurrent with a large loss of genetic diversity? 2) Are morphological changes at the Pleistocene/Holocene boundary the product of adaptation, or immigration? 3) Are major shifts in morphological and genetic variation correlated with climate change? Using aDNA, AMS radiocarbon dates, stable isotope analyses, morphological analyses, and previous data from NTC this project will investigate changes in climatic conditions and how they correlate with genetic diversity and morphological change. This research will lead to a better understanding of how climate change drives extinction and may reveal correlations between climate change, metapopulation structure and changes in genetic and morphological variation.

Remarkably preserved bones of rat-sized creatures excavated in an Indian coal mine may come from close relatives of the first primatelike animals, researchers say. A set of 25 arm, leg, ankle and foot fossils, dating to roughly 54.5 million years ago, raises India’s profile as a possible hotbed of early primate evolution, say evolutionary biologist Rachel Dunn of Des Moines University in Iowa and her colleagues. Bones from Vastan coal mine in Gujarat, India’s westernmost state, indicate that these tiny tree-dwellers resembled the first primates from as early as 65 million years ago, the scientists report in the October Journal of Human Evolution. These discoveries add to previously reported jaws, teeth and limb bones of four ancient primate species found in the same mine. “The Vastan primates probably approximate a common primate ancestor better than any fossils found previously,” says paleontologist and study coauthor Kenneth Rose of Johns Hopkins University School of Medicine. The Vastan animals were about the size of living gray mouse lemurs and dwarf lemurs, weighing roughly 150 to 300 grams (roughly half a pound), the investigators estimate. Dunn’s group has posted 3-D scans of the fossils to Morphosource.org (SN: 3/19/16, p. 28) so other researchers can download and study the material. Most Vastan individuals possessed a basic climbing ability unlike the more specialized builds of members of the two ancient primate groups that gave rise to present-day primates, the researchers say. One of those groups, omomyids, consisted of relatives of tarsiers, monkeys and apes. The other group, adapoids, included relatives of lemurs, lorises and bushbabies. The Indian primates were tree-dwellers but could not leap from branch to branch like lemurs or ascend trees with the slow-but-sure grips of lorises, the new report concludes. Vastan primates probably descended from a common ancestor of omomyids and adapoids, the researchers propose. India was a drifting landmass headed north toward a collision with mainland Asia when the Vastan primates were alive. Isolated on a huge chunk of land, the Indian primates evolved relatively slowly, retaining a great number of ancestral skeletal traits, Rose suspects. “It’s possible that India played an important role in primate evolution,” says evolutionary anthropologist Doug Boyer of Duke University. A team led by Boyer reported in 2010 that a roughly 65-million-year-old fossil found in southern India might be a close relative of the common ancestor of primates, tree shrews and flying lemurs (which glide rather than fly and are not true lemurs). One possibility is that primates and their close relatives evolved in isolation on the island continent of India between around 65 million and 55 million years ago, Boyer suggests. Primates then spread around the world once India joined Asia by about 50 million years ago. That’s a controversial idea. An increasing number of scientists suspect primates originated in Asia. Chinese primate fossils dating to 56 million to 55 million years ago are slightly older than the Vastan primates (SN: 6/29/13, p. 14; SN: 1/3/04, p. 4). The Chinese finds show signs of having been omomyids. And in at least one respect, Boyer says, some of the new Vastan fossils may be more specialized than their discoverers claim. Vastan ankle bones, for instance, look enough like those of modern lemurs to raise doubts that the Indian primates were direct descendants of primate precursors, he holds. Dunn, however, regards the overall anatomy of the Vastan fossils as “the most direct evidence we have” that ancestors of early primates lacked lemurs’ leaping abilities, contrary to what some researchers have argued.

The La Brea asphalt seeps are famous for the predators entombed there. Dire wolves and the sabercat Smilodon – the site’s mascot – are the exotic Ice Age stars that everyone comes to see. The third most-numerous carnivore found there doesn’t enjoy such celebrity. In fact, there are some who consider it a beast of ill-repute. If you follow the path of the Page Museum around its circular path, there’s a little alcove near the end that presents some modern animals that lived in Ice Age times. And there, howling before an artistic depiction of itself, is that third most-abundant carnivore – the coyote. Coyotes are familiar canids. Not only are they common, but they’re so ecologically flexible that they’ve actually taken up residence with us. Compared to a dire wolf or sabercat the coyote seems familiar and plain, but it would be a mistake to overlook the beast. Coyotes are survivors of the Ice Age, and their bones record tales of evolution and extinction. Des Moines University paleontologist Julie Meachen started to draw out some of these details in a 2012 study on coyote body size. Ice Age coyotes – such as those found at La Brea – were larger than their modern counterparts, and this was often attributed to the idea that a larger body would’ve helped the carnivores better conserve body heat during the Ice Age. But Meachen and coauthor Joshua Samuels found that this wasn’t the case. By comparing coyote changes with alterations in gray wolf body size, Meachen and Samuels found that climate change couldn’t account for the shrinking coyotes. Instead, Ice Age coyotes may have been larger because size was an advantage during a time when there was a broader guild of big predators stalking the land. Once the dire wolves, sabercats, and American lions went extinct, competition for prey ceased to be so intense and coyotes became smaller. Also, many of the large prey animals of the Ice Age – such as horses and camels – went extinct, too, meaning less food on the hoof for coyote packs. Now Meachen and team of collaborators have followed up on the body-size study with an investigation of coyote mandibles from the Ice Age to the present. The researchers drew from three pools of coyote remains – 29,000-13,000 year old Ice Age jaws; 10,000-8,000 year old Holocene jaws; and modern jaws – and created 2D models of each jaw to track how certain landmarks varied between individuals and through time. The results buttressed the conclusions of the previous study. Ice Age coyotes were generally larger and more carnivorous than their modern counterparts. The evidence is in the killing and cutting part of the jaw. The shearing portion of the Ice Age coyote tooth row was longer and underlain by a deeper, more robust portion of jaw bone, while the grinding portion of the tooth row was shorter compared to today’s modern, more omnivorous coyotes. The Holocene coyotes were intermediate in form, befitting their placement in time between the two. Along with the sheer number of specimens found at La Brea and tooth wear that indicates gnawing on bone, the new evidence adds to the emerging picture of larger, more carnivorous Ice Age coyotes that likely worked in groups to bring down large prey, as well as defend and steal carcasses. So why have coyotes shrunk with time? Meachen and colleagues suggest that the disappearance of other carnivores and the rise of gray wolves was crucial. Gray wolves were present in North America during the Ice Age, but they were relatively rare compared to dire wolves. Once dire wolves and some of the other large Ice Age carnivores went extinct, however, gray wolves were able to gain more of a foothold. This was bad news for the coyotes. Modern gray wolves often kill large coyotes, and the same was likely true in the wake of the end-Pleistocene extinction. As a result, Meachen and colleagues propose, the wolves put increased pressure on coyotes to become smaller and adapt to a lifestyle of pouncing on smaller prey. The end-Ice Age extinction was not just about loss. It also opened up new possibilities and interactions that have been affecting the survivors for the past 10,000 years. So the next time you see a coyote loping through the sagebrush or even stealing a snack from a garbage can, stop a moment to appreciate the adaptable nature of a canid that has changed with the times.
