Parochialism or self-consciousness? Internationality in medical history journals 1997-2006

Research councils, universities and funding agencies are increasingly asking for tools to measure the quality of research in the humanities. One of their preferred methods is a ranking of journals according to their supposed level of internationality. Our quantitative survey of seventeen major journals of medical history reveals the futility of such an approach. Most journals have a strong national character with a dominance of native language, authors and topics. The most common case is a paper written by a local author in his own language on a national subject regarding the nineteenth or twentieth century. American and British journals are taken notice of internationally but they only rarely mention articles from other history of medicine journals. Continental European journals show a more international review of literature, but are in their turn not noticed globally. Increasing specialisation and fragmentation has changed the role of general medical history journals. They run the risk of losing their function as international platforms of discourse on general and theoretical issues and major trends in historiography, to international collections of papers. Journal editors should therefore force their authors to write a more international report, and authors should be encouraged to submit papers of international interest and from a more general, transnational and methodological point of view.

Diagnostic value of animal-side antibody assays for rapid detection of Mycobacterium bovis or Mycobacterium microti infection in South American camelids

Tuberculosis (TB) in South American camelids (SAC) is caused by Mycobacterium bovis or Mycobacterium microti. Two serological methods, rapid testing (RT) and the dual-path platform (DPP) assay, were evaluated using naturally infected SAC. The study population included 156 alpacas and 175 llamas in Great Britain, Switzerland, and the United States. TB due to M. bovis (n = 44) or M. microti (n = 8) in 35 alpacas and 17 llamas was diagnosed by gross pathology examination and culture. Control animals were from herds with no TB history. The RT and the DPP assay showed sensitivities of 71% and 74%, respectively, for alpacas, while the sensitivity for llamas was 77% for both assays. The specificity of the DPP assay (98%) was higher than that of RT (94%) for llamas; the specificities of the two assays were identical (98%) for alpacas. When the two antibody tests were combined, the parallel-testing interpretation (applied when either assay produced a positive result) enhanced the sensitivities of antibody detection to 89% for alpacas and 88% for llamas but at the cost of lower specificities (97% and 93%, respectively), whereas the serial-testing interpretation (applied when both assays produced a positive result) maximized the specificity to 100% for both SAC species, although the sensitivities were 57% for alpacas and 65% for llamas. Over 95% of the animals with evidence of TB failed to produce skin test reactions, thus confirming concerns about the validity of this method for testing SAC. The findings suggest that serological assays may offer a more accurate and practical alternative for antemortem detection of camelid TB.

The Persistence of Shattered Dreams: a Comparative Study of the Audacity of the American Dream

In my thesis, I use historical and literary analysis to study how the concept of the American Dream was popularized during the Great Depression and how cultural understanding of the term has changed following the 2008 Recession. By comparing popular media, literature, and political documents within a historical framework from the 1930s and after 2008 through the present day, I analyze how the term ¿American Dream¿ has persisted as an element of the United States¿ national ethos. I explore why the language of the American Dream does not appear to carry the same resonance in American society as in the 1930s, even though the post-2008 economic environment is somewhat comparable to conditions created by the Great Depression and associated reform measures. This comparative historical approach in scholarly studies of the American Dream is unique because the two periods have not previously been discussed in relation to one another in order to show transformations in cultural understanding of the Dream. The American Dream, both embodying a dual identity as an aspiration to aspire to and also as a delusional fantasy which can lead to cynicism, is a highly complex idea in lived experience. The concept¿s ambiguous nature allows for individuals to interpret it differently, allowing for the term to remain resilient throughout different periods in United States history. While the meaning of the term has been subject to change, it is grounded upon an idealistic concept of American individualism and hope that through one¿s merit, one will be able to achieve one¿s vision of success. Through interdisciplinary analysis, I show that the American Dream will alter to suit the needs of contemporary society and the term¿s power will continue to endure in society despite evidence of rising cynicism since 2008.

Eruptive history of Maderas volcano using new 40Ar/39Ar ages and geochemical analyses

Maderas volcano is a small, andesitic stratovolcano located on the island of Ometepe, in Lake Nicaragua, Nicaragua with no record of historic activity. Twenty-one samples were collected from lava flows from Maderas in 2010. Selected samples were analyzed for whole-rock geochemical data using ICP-AES and/or were dated using the 40Ar/39Ar method. The results of these analyses were combined with previously collected data from Maderas as well as field observations to determine the eruptive history of the volcano and create a geologic map. The results of the geochemical analyses indicate that Maderas is a typical Central American andesitic volcano similar to other volcanoes in Nicaragua and Costa Rica and to its nearest neighbor, Concepción volcano. It is different from Concepción in one important way – higher incompatible elements. Determined age dates range from 176.8 ± 6.1 ka to 70.5 ± 6.1 ka. Based on these ages and the geomorphology of the volcano which is characterized by a bisecting graben, it is proposed that Maderas experienced two clear generations of development with three separate phases of volcanism: initial build-up of the older cone, pre-graben lava flows, and post-graben lava flows. The ages also indicate that Maderas is markedly older than Concepción which is historically active. Results were also analyzed regarding geologic hazards. The 40Ar/39Ar ages indicate that Maderas has likely been inactive for tens of thousands of years and the risk of future volcanic eruptions is low. However, earthquake, lahar and landslide hazards exist for the communities around the volcano. The steep slopes of the eroded older cone are the most likely source of landslide and lahar hazards.

THE FANNED FLAMES OF DISCONTENT: A SOLIDARITY-INSPIRED HISTORY OF THE IDENTITY/IDEOLOGY, CULTURAL HISTORY, AND RHETORICAL STRATEGIES OF THE WOBBLIES DURING THE 1916 MINNESOTA IRON ORE STRIKE

Rooted in critical scholarship this dissertation is an interdisciplinary study, which contends that having a history is a basic human right. Advocating a newly conceived and termed, Solidarity-inspired History framework/practice perspective, the dissertation argues for and then delivers a restorative voice to working-class historical actors during the 1916 Minnesota Iron Ore Strike. Utilizing an interdisciplinary methodological framework the dissertation combines research methods from the Humanities and the Social Sciences to form a working-class history that is a corrective to standardized studies of labor in the late 19th and early 20th centuries. Oftentimes class interests and power relationships determine the dominant perspectives or voices established in history and disregard people and organizations that run counter to, or in the face of, customary or traditional American themes of patriotism, the Protestant work ethic, adherence to capitalist dogma, or United States exceptionalism. This dissertation counteracts these traditional narratives with a unique, perhaps even revolutionary, examination of the 1916 Minnesota Iron Ore Strike. The intention of this dissertation's critical perspective is to poke, prod, and prompt academics, historians, and the general public to rethink, and then think again, about the place of those who have been dislocated from or altogether forgotten, misplaced, or underrepresented in the historical record. Thus, the purpose of the dissertation is to give voice to historical actors in the dismembered past. Historical actors who have run counter to traditional American narratives often have their body of "evidence" disjointed or completely dislocated from the story of our nation. This type of disremembering creates an artificial recollection of our collective past, which de-articulates past struggles from contemporary groups seeking solidarity and social justice in the present. Class-conscious actors, immigrants, women, the GLBTQ community, and people of color have the right to be remembered on their own terms using primary sources and resources they produced. Therefore, similar to the Wobblies industrial union and its rank-and-file, this dissertation seeks to fan the flames of discontented historical memory by offering a working-class perspective of the 1916 Strike that seeks to interpret the actions, events, people, and places of the strike anew, thus restoring the voices of these marginalized historical actors.

Fructose overconsumption causes dyslipidemia and ectopic lipid deposition in healthy subjects with and without a family history of type 2 diabetes

BACKGROUND: Both nutritional and genetic factors are involved in the pathogenesis of nonalcoholic fatty liver disease and insulin resistance. OBJECTIVE: The aim was to assess the effects of fructose, a potent stimulator of hepatic de novo lipogenesis, on intrahepatocellular lipids (IHCLs) and insulin sensitivity in healthy offspring of patients with type 2 diabetes (OffT2D)--a subgroup of individuals prone to metabolic disorders. DESIGN: Sixteen male OffT2D and 8 control subjects were studied in a crossover design after either a 7-d isocaloric diet or a hypercaloric high-fructose diet (3.5 g x kg FFM(-1) x d(-1), +35% energy intake). Hepatic and whole-body insulin sensitivity were assessed with a 2-step hyperinsulinemic euglycemic clamp (0.3 and 1.0 mU x kg(-1) x min(-1)), together with 6,6-[2H2]glucose. IHCLs and intramyocellular lipids (IMCLs) were measured by 1H-magnetic resonance spectroscopy. RESULTS: The OffT2D group had significantly (P < 0.05) higher IHCLs (+94%), total triacylglycerols (+35%), and lower whole-body insulin sensitivity (-27%) than did the control group. The high-fructose diet significantly increased IHCLs (control: +76%; OffT2D: +79%), IMCLs (control: +47%; OffT2D: +24%), VLDL-triacylglycerols (control: +51%; OffT2D: +110%), and fasting hepatic glucose output (control: +4%; OffT2D: +5%). Furthermore, the effects of fructose on VLDL-triacylglycerols were higher in the OffT2D group (group x diet interaction: P < 0.05). CONCLUSIONS: A 7-d high-fructose diet increased ectopic lipid deposition in liver and muscle and fasting VLDL-triacylglycerols and decreased hepatic insulin sensitivity. Fructose-induced alterations in VLDL-triacylglycerols appeared to be of greater magnitude in the OffT2D group, which suggests that these individuals may be more prone to developing dyslipidemia when challenged by high fructose intakes. This trial was registered at clinicaltrials.gov as NCT00523562.

Tuberculosis caused by Mycobacterium microti in South American camelids

BACKGROUND: Infection with Mycobacterium microti can cause chronic disease in animals and threaten human health through its zoonotic potential. OBJECTIVE: To describe clinical findings, diagnostic investigations, necropsy, and epidemiology results in South American camelids (SAC) infected with M. microti, member of the Mycobacterium tuberculosis complex. ANIMALS: Eleven SAC with tuberculous lesions. METHODS: Description of 10 llamas and 1 alpaca, aged 4-18 years, from 6 herds with a history of wasting and weakness admitted to the Vetsuisse-Faculty of Berne over 8 years. RESULTS: Clinical signs included weight loss, recumbency, and anorexia in late stages of the disease. Respiratory problems were seen in 6 animals of 11. No consistent hematologic abnormalities were identified. Suspect animals were examined in detail by abdominal ultrasonography and thoracic radiology. Abnormal findings such as enlarged mediastinal, mesenteric, or hepatic lymph nodes were seen only in animals with advanced disease. Single comparative intradermal tuberculin test with bovine protein purified derivate (PPD) and avian PPD was negative in all animals. At necropsy, typical tuberculous lesions were found, and confirmed by bacteriological smear and culture, molecular methods, or both. CONCLUSIONS AND CLINICAL IMPORTANCE: Infection caused by M. microti should be considered a differential diagnosis in chronic debilitating disease with or without respiratory signs in SAC. Antemortem confirmation of the diagnosis remains challenging at any stage of infection. Because cases of M. microti infection have been reported in immunocompromized human patients, the zoonotic potential of the organism should be kept in mind when dealing with this disease in SAC.

An examination of the Gonorrhea Cases & Places Study: An analysis of the Theory of Gender and Power, Situational/Environmental Variables Theory, and Sexual Script Theory as it relates to risky sexual behavior in African American adults

Objective. The purpose of the study is to provide a holistic depiction of behavioral & environmental factors contributing to risky sexual behaviors among predominantly high school educated, low-income African Americans residing in urban areas of Houston, TX utilizing the Theory of Gender and Power, Situational/Environmental Variables Theory, and Sexual Script Theory. Methods. A cross-sectional study was conducted via questionnaires among 215 Houston area residents, 149 were women and 66 were male. Measures used to assess behaviors of the population included a history of homelessness, use of crack/cocaine among several other illicit drugs, the type of sexual partner, age of participant, age of most recent sex partner, whether or not participants sought health care in the last 12 months, knowledge of partner's other sexual activities, symptoms of depression, and places where partner's were met. In an effort to determine risk of sexual encounters, a risk index employing the variables used to assess condom use was created categorizing sexual encounters as unsafe or safe. Results. Variables meeting the significance level of p<.15 for the bivariate analysis of each theory were entered into a binary logistic regression analysis. The block for each theory was significant, suggesting that the grouping assignments of each variable by theory were significantly associated with unsafe sexual behaviors. Within the regression analysis, variables such as sex for drugs/money, low income, and crack use demonstrated an effect size of ≥ ± 1, indicating that these variables had a significant effect on unsafe sexual behavioral practices. Conclusions. Variables assessing behavior and environment demonstrated a significant effect when categorized by relation to designated theories.
