    Full Text Available American tegumentary leishmaniasis (ATL can affect the skin or mucosa (mucocutaneous leishmaniasis - MCL including the oral cavity. MCL oral lesions are often confused with other oral diseases, delaying diagnosis and specific treatment, and increasing the likelihood of sequelae. Thus, increasing the knowledge of the evolution of ATL oral lesions can facilitate its early diagnosis improving the prognosis of healing.Evaluate the frequency of ATL oral lesion and describe its clinical, laboratory and therapeutic peculiarities.A descriptive transversal study was carried out, using data from medical records of 206 patients with MCL examined at the outpatient clinics-IPEC-Fiocruz between 1989 and 2013. Proportions were calculated for the categorical variables and the association among them was assessed by the Pearson's chi-square test. Measures of central tendency and dispersion were used for the continuous variables and their differences were assessed by both parametric (t test and non parametric (Mann-Whitney tests. P-values <0.05 were considered as significant.The most affected site was the nose, followed by the mouth, pharynx and larynx. Seventy eight (37.9% have oral lesions and the disease presented a lower median of the evolution time than in other mucous sites as well as an increased time to heal. The presence of oral lesion was associated with: the presence of lesions in the other three mucosal sites; a smaller median of the leishmanin skin test values; a longer healing time of the mucosal lesions; a higher recurrence frequency; and a smaller frequency of treatment finishing and healing. When the oral lesion was isolated, it was associated with an age 20 years lower than when the oral lesion was associated with other mucosal sites.Considering the worst therapy results associated with the presence of oral lesions, we suggest that lesions in this location represent a factor of worse prognosis for MCL.

    Traditional diagnostic methods used to detect American Tegumentary Leishmaniasis, such as histopathology using biopsy samples, culture techniques, and direct search for parasites, have low sensitivity and require invasive collection procedures. This study evaluates the efficiency of noninvasive sampling methods (swab) along with Polymerase Chain Reaction (PCR) for diagnosing American Tegumentary Leishmaniasis using skin and mucous samples from 25 patients who had tested positive for leishmaniasis. The outcome of the tests performance on swab samples was compatible with PCR results on biopsy samples. The findings have also shown that PCR-kDNA test is more efficient than PCR-HSP70 and qPCR tests (sensitivity of 92.3%, 40.7%, and 41%, respectively). Given the high sensitivity of the tests and the fact that the sampling method using swabs affords greater patient comfort and safety, it could be said that this method is a promising alternative to conventional biopsy-based methods for the molecular diagnosis of leishmaniasis.

    The present study reports the production of the rabbit anti-Leishmania (L.) chagasi hyperimmune serum, the standardization of the immunohistochemistry (IHC) technique and the evaluation of its employment in cutaneous leishmaniasis (CL) lesions diagnosed by Leishmania sp. culture isolation. Thirty fragments of active CL lesions were examined as well as 10 fragments of cutaneous mycosis lesions as control group. IHC proved more sensitive in detecting amastigotes than conventional hematoxylin-eosin (HE) stained slides: the former was positive in 24 (80%) biopsies whereas the latter, in 16 (53%) (p = 0.028). The reaction stained different fungus species causing cutaneous mycosis. Besides, positive reaction was noticed in mononuclear and endothelial cells. Nevertheless, this finding was present in the control group biopsies. It is concluded that IHC showed good sensitivity in detecting amastigotes.

    Skin inflammation plays an important role during the healing of American tegumentary leishmaniasis (ATL), the distribution of cells in active lesions may vary according to disease outcome and parasite antigens in ATL scars have already been shown. We evaluated by immunohistochemistry, 18 patients with 1- or 3-year-old scars and the corresponding active lesions and compared them with healthy skin. Small cell clusters in scars organized as in the active lesions spreaded over the fibrotic tissue were detected, as well as close to vessels and cutaneous glands, despite a reduction in the inflammatory process. Analysis of 1-year-old scar tissue showed reduction of NOS2, E-selectin, Ki67, Bcl-2 and Fas expression. However, similar percentages of lymphocytes and macrophages were detected when compared to active lesions. Only 3-year-old scars showed reduction of CD3(+), CD4(+) and CD8(+)T cells, in addition to reduced expression of NOS2, E-selectin, Ki67 and BCl-2. These results suggest that the pattern of cellularity of the inflammatory reaction observed in active lesions changes slowly even after clinical healing. Analysis of 3-year-old scars showed reduction of the inflammatory reaction as demonstrated by decrease in inflammatory cells and in the expression of cell-activity markers, suggesting that the host-parasite balance was only established after that period.

    Pyogranulomatous lesions from 80 dogs with sporotrichosis and 26 dogs with American tegumentary leishmaniasis (ATL) were compared microscopically in order to identify features that would support the diagnostic suspicion and direct the subsequent search for the aetiological agent of either infection. Odds ratios and their respective 95% confidence intervals were calculated in order to evaluate the impact of the microscopical findings on the diagnosis of either disease. Lesions with well-formed granulomata were 14 times more likely to be due to sporotrichosis than ATL. Marked neutrophil infiltration into granulomata was 12.26 times more likely to be associated with sporotrichosis when compared with lesions having mild neutrophilic infiltration. Absence of lymphocytes and macrophages in the peripheral infiltrate was associated with a 9.71 and 4.93 higher chance, respectively, of being sporotrichosis rather than ATL compared with lesions where these cells were present. Lesions with a perivascular, perifollicular and interstitial peripheral inflammatory infiltrate were 5.48 times more likely to be due to sporotrichosis than ATL when compared with lesions with a diffuse peripheral infiltrate. Histopathological analysis may therefore contribute to the diagnosis of sporotrichosis or ATL skin lesions in dogs since this method permits the identification of features that direct the diagnostic suspicion, thus facilitating the search for the aetiological agent in histological sections, permitting the precise request of subsequent tests and thereby reducing costs and time taken to achieve a definitive diagnosis and the initiation of appropriate therapy.

    Full Text Available We aimed to assess and synthesize the information available in the literature regarding the treatment of American tegumentary leishmaniasis in special populations. We searched MEDLINE (via PubMed, EMBASE, LILACS, SciELO, Scopus, Cochrane Library and mRCT databases to identify clinical trials and observational studies that assessed the pharmacological treatment of the following groups of patients: pregnant women, nursing mothers, children, the elderly, individuals with chronic diseases and individuals with suppressed immune systems. The quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE approach. The available evidence suggests that the treatments of choice for each population or disease entity are as follows: nursing mothers and children (meglumine antimoniate or pentamidine, patients with renal disease (amphotericin B or miltefosine, patients with heart disease (amphotericin B, miltefosine or pentamidine, immunosuppressed patients (liposomal amphotericin, the elderly (meglumine antimoniate, pregnant women (amphotericin B and patients with liver disease (no evidence available. The quality of evidence is low or very low for all groups. Accurate controlled studies are required to fill in the gaps in evidence for treatment in special populations. Post-marketing surveillance programs could also collect relevant information to guide treatment decision-making.

    Rio de Janeiro State in Brazil is an endemic area of American tegumentary leishmaniasis (ATL) induced by Leishmania (Viannia) braziliensis. Objective Our purpose was to describe the main clinical and epidemiologic characteristics of the disease in Rio de Janeiro State. Patients from endemic areas of Rio de Janeiro State attending the Evandro Chagas Hospital were included in the study. A general physical, dermatologic, and otorhinolaryngologic examination was performed in all patients, as well as a Leishmanin skin test. Skin biopsy specimens were obtained and utilized for touch preparations (stained with Leishman dye), culture in special media (Nicolle, Nevy and McNeal; NNN), and histopathologic examination after hematoxylin and eosin stain. Positive cultures were identified with regard to species by the isoenzyme technique. Therapy with pentavalent antimonial compounds was employed in all cases. Eco-epidemiologic characteristics were studied through regular field visits to endemic foci. Cutaneous disease was present in 87.2% of patients, and mucosal disease in only 12.7%. A single ulcerative cutaneous lesion was the most common clinical presentation. Demonstration of the parasite was always difficult and culture in special media gave the best results for diagnosis. The species involved in transmission was Leishmania (Viannia) braziliensis. Vectors included phlebotomine sand flies (Diptera: Psychodidae) of the genus Lutzomyia, and the most common species was Lutzomyia intermedia, captured mainly on the external walls of houses. ATL in Rio de Janeiro is mostly a cutaneous disease. In general, the cases showed great sensitivity to antimony. A pattern of peridomestic transmission seems to be the rule.

    Antibodies against Leishmania peptides (Lbr-peps) and desmogleins (Dsgs) have been reported in pemphigus foliaceus (PF) and leishmaniasis patients, respectively. We aimed to compare serological and genetic features in a Brazilian region endemic for American tegumentary leishmaniasis (ATL) and pemphigus. Commercial anti-Dsg ELISA and in-house ELISA with Lbr-peps were used to determine the serological profile, in addition to immunoblotting (IB) and indirect immunofluorescence (IIF) assays. HLA-DRB1 and -DQA1/DQB1 alleles were characterized by PCR combined with sequence-specific oligonucleotide probes (PCR-SSOP). The serological and genetic profiles were compared using 78 PF, 62 pemphigus vulgaris (PV) and 58 ATL patients against 163 and 1592 healthy controls, respectively. Some ATL patients showed positive results for anti-Dsg1 and/or anti-Dsg3 antibodies. They also revealed 130, 160 and/or 230 kDa epidermal peptides in IB. Moreover, some ATL samples exhibited pemphigus or a bullous pemphigoid pattern in IIF. ELISA and IB assays showed Lbr-peps in pemphigus patients. HLA-DQA1*01 and -DQA1*01:02 were protective and susceptibility alleles for ATL, respectively, but the opposite for pemphigus. Anti-Dsgs in ATL may represent epiphenomena. Anti-Lbr-pep antibodies in pemphigus suggest a previous infection. A differential association of the HLA profile may contribute to the lack of co-association between pemphigus and ATL. © The Author 2017.

    Background American tegumentary leishmaniasis (ATL) is endemic in Latin America, where Brazil has over 27 thousand cases per year. The aim of the present study was to develop an immunohistochemical method (IHC) for ATL diagnosis. For this purpose, we used serum from a dog naturally infected with Leishmania (L) infantum (canine hyperimmune serum) as the primary antibody, followed by a detection system with a secondary biotinylated antibody. Methodology Skin samples were obtained from 73 patients in an endemic area of Caratinga, Minas Gerais (MG) State, Brazil all testing positive for ATL with the Montenegro skin test, microscopy, and PCR. Canine hyperimmune serum of a dog naturally infected with Leishmania (L.) infantum was employed as a primary antibody in an immunohistochemical diagnostic method using streptavidin-biotin peroxidase. To assess the specificity of this reaction, IHC assays employing two monoclonal antibodies were carried out. As the polymer-based technology is less time-consuming and labor intensive than the IHC labeled streptavidin-biotin peroxidase method, we compared the two methods for all samples. Results The IHC method detected ATL in 67 of the 73 cases (91.8%). Immunolabeled parasites were primarily detected inside macrophages either in the superficial or the deep dermis. Detection was facilitated by the high contrast staining of amastigotes (dark brown) against the light blue background. A lower detection rate (71.2%) was observed with the both of the monoclonal Leishmania antibodies compared to the canine hyperimmune serum. This may have been due to a non-specific background staining observed in all histological samples rendering positive detection more difficult. The higher efficacy of the canine hyperimmune serum in the IHC method was confirmed by the method using streptavidin-biotin peroxidase as well as that with the polymer-based technology (biotin-avidin-free system). Conclusions The data are encouraging with regard to validating IHC

    American tegumentary leishmaniasis (ATL) is endemic in the State of Rio de Janeiro, with the highest incidence observed in the municipalities along the Southern coast. A total of 169 human cases were reported from 1993 to 1995 in the municipality of Paraty, representing 15% of all case reports in the State of Rio de Janeiro during that period. From March to December, 1996, a survey was conducted in endemic american tegumentary leishmaniasis (ATL) areas (Praia Grande, Taquari, Várzea do Machado, and Graúna) in Paraty. 326 households with 215 pet dogs were surveyed. The initial study consisted of taking venous blood samples to perform RIFI and ELISA tests. The canine skin test was performed during the same visit and was positive in 8.8% of dogs. Of the 215 dogs, 5 presented lesions suspected of ATL; biopsies and the vacuum aspiration technique were performed on these cases. Correlating the study areas with the results obtained, some dogs presented sub-clinical infection, highly relevant to studies on canine ATL infection in the State of Rio de Janeiro.

  12. Variability Modeling of Rainfall, Deforestation, and Incidence of American Tegumentary Leishmaniasis in Orán, Argentina, 1985–2007

    Full Text Available American tegumentary leishmaniasis (ATL is a disease transmitted to humans by the female sandflies of the genus Lutzomyia. Several factors are involved in the disease transmission cycle. In this work only rainfall and deforestation were considered to assess the variability in the incidence of ATL. In order to reach this goal, monthly recorded data of the incidence of ATL in Orán, Salta, Argentina, were used, in the period 1985–2007. The square root of the relative incidence of ATL and the corresponding variance were formulated as time series, and these data were smoothed by moving averages of 12 and 24 months, respectively. The same procedure was applied to the rainfall data. Typical months, which are April, August, and December, were found and allowed us to describe the dynamical behavior of ATL outbreaks. These results were tested at 95% confidence level. We concluded that the variability of rainfall would not be enough to justify the epidemic outbreaks of ATL in the period 1997–2000, but it consistently explains the situation observed in the years 2002 and 2004. Deforestation activities occurred in this region could explain epidemic peaks observed in both years and also during the entire time of observation except in 2005–2007.

    The study of American tegumentary leishmaniasis (ATL) lesions might contribute to the understanding of the dynamics of the infection. To examine the cellular infiltrate of cutaneous ATL lesions and to compare these results with the detection of the parasites and clinical data. Lesions of 19 patients with ATL were evaluated through immunohistochemical analysis. The lesions presented an inflammatory reaction mainly consisting of T cells and macrophages. Analysis of the expression of nitric oxide synthase type 2 (NOS2) showed that its intensity was directly correlated with the number of CD3+ T cells. We also observed an association between high NOS2 expression and low quantity of parasites, highlighting the importance of NOS2 in the elimination of parasites. The present results suggest that (i) the inflammatory process is intense in cutaneous ATL lesions and maintains a similar activity for several months; (ii) the dynamics of cell infiltration change during this period, with a gradual decrease in CD8+ T cells, probably correlated with a reduction in the parasite number; (iii) neutrophils may participate in the inflammatory process even during later stages of infection; (iv) the relative increase in the number of CD4+ T cells associated with the onset of fibrosis may suggest a participation of these cells in the control of the inflammatory process; and (v) late lesions with tendency for healing usually show focal inflammation. The study of healing lesions might contribute to the understanding of the late steps of the control of the inflammatory process in ATL lesions.

    American tegumentary leishmaniasis (ATL) and sporotrichosis exhibit similar histopathology and low frequencies of microorganism detection. This study seeks to identify microscopic alterations that can distinguish between these diseases. Haematoxylin and eosin stained slides of 171 ATL and 97 sporotrichosis samples from active cutaneous lesions were examined for histopathological alterations. The lesions were diagnosed by isolating the agent (which was not visible) in culture. An intuitive diagnosis was assigned to each slide. The strength of the association between the histopathological findings and the diagnosis was estimated by an odds ratio, and each finding was graded according to a regression model. A score was assigned to each sample based on the histopathological findings. A study of the interobserver reliability was performed by calculating kappa coefficients of the histopathological findings and intuitive diagnoses. The markers 'macrophage concentration', 'tuberculoid granuloma' and 'extracellular matrix degeneration' were associated with ATL. 'Suppurative granuloma', 'stellate granuloma', 'different types of giant cells', 'granulomas in granulation tissue' and 'abscess outside the granuloma' were associated with a diagnosis of sporotrichosis. 'Macrophage concentration' and 'suppurative granuloma' had the highest (substantial and almost perfect, respectively) reliability. The regression model score indicated 92.0% accuracy. The intuitive diagnosis had 82.5% diagnostic accuracy and substantial reliability. Taking into account the clinical and epidemiological context, some histopathological alterations might be useful for the differential diagnosis between ATL and sporotrichosis cutaneous lesions in cases in which the aetiological agent is not visible. © 2012 The Authors.

    American tegumentary leishmaniasis (ATL) and human immunodeficiency virus (HIV) are both common infectious diseases in the Brazilian Amazon with overlapping expansion areas, which leads to the occurrence of Leishmania/HIV coinfection. Most ATL/HIV–acquired immunodeficiency syndrome (AIDS) association cases have been reported from areas where Leishmania (Viannia) braziliensis is the main pathogen; this finding is in contrast with the Amazon region, where L. (V.) guyanensis is the most implicated agent, implying distinct clinical and therapeutic aspects. We describe 15 cases of ATL/HIV coinfection treated in a tertiary care center in the Brazilian Amazon between 1999 and 2008. Thirteen patients presented with diverse clinical manifestations of cutaneous leishmaniasis, and four of them had disseminated forms; two patients presented with mucosal leishmaniasis (ML). Seven patients required more than one course of treatment. The particularities of ATL/HIV-AIDS association in L. (V.) guyanensis-endemic areas require efforts for an increased understanding of its burden and subsequent improvements in case management. PMID:21896816

    The most severe clinical form of American tegumentary leishmaniasis (ATL) due to Leishmania braziliensis is mucosal leishmaniasis (ML), characterized by destructive lesions in the facial mucosa. We performed a retrospective cohort study of 109 ATL patients from Rio de Janeiro State, Brazil, where ATL is caused by L. braziliensis, to evaluate the influence of intestinal parasite coinfections in the clinical course of ATL. Parasitological stool examination (PSE) was performed with samples from all patients by the sedimentation, Kato-Katz and Baermann-Moraes methods. The diagnosis of ATL was made from lesion biopsies by direct observation of amastigotes in Giemsa-stained imprints, isolation of Leishmania promastigotes or histopathological examination. All patients were treated with meglumine antimoniate. Patients with positive PSE had a frequency of mucosal lesions significantly higher than those with negative PSE (p<0.005). The same was observed for infections with helminths in general (p<0.05), with nematodes (p<0.05) and with Ascaris lumbricoides (p<0.05), but not for protozoan infections. Patients with intestinal parasites had poor response to therapy (therapeutic failure or relapse) significantly more frequently than the patients with negative stool examination (p<0.005). A similar difference (p<0.005) was observed between patients with positive and negative results for intestinal helminths, but not for intestinal protozoa. Patients with positive PSE took significantly longer to heal than those with negative PSE (p<0.005). A similar difference was observed for intestinal helminth infections (p<0.005), but not for protozoan infections. Our results indicate a deleterious influence of intestinal helminth infections in the clinical course of ATL and evidence for the first time an association between ML and these coinfections, particularly with nematodes and A. lumbricoides.

    The aim of the present study was to analyze the status of the American Tegumentary Leishmaniasis (ATL) in the state of Rio de Janeiro, from 2004 to 2013, through its spatiotemporal distribution. We also described variables considered relevant to the epidemiology of the disease, such as the clinical form, gender, ethnic group, age group, and progression of disease. This is a descriptive study, which used notified secondary data from the Brazilian Information System of Notifiable Diseases (SINAN), Ministry of Health, Brazil, regarding confirmed diagnoses. To help the calculation of coefficients of detection and mortality, we used population data from the Brazilian Institute of Geography and Statistics (IBGE). We analyzed 1,470 cases of ATL with the predominance of the cutaneous clinical form (1,292/87.89%). The data has also revealed seven deaths, a predominance of males (922/62.72%), and a higher incidence of ATL in the white ethnic group (731/49.72%). We observed a high incidence of ATL in the group of 20 - 39 years old (477/32.44%). We concluded that there was a decrease in the number of ATL cases in the state of Rio de Janeiro, based on a coefficient of detection of 1.44/100.000 inhabitants in 2004 decreasing to 0.20/100.000 inhabitants in 2013. The localities with the highest occurrences of ATL were the metropolitan region (843 cases) and the municipality of Rio de Janeiro (740 cases). In 2005, the highest incidence of the disease was observed (351 cases) in the study. Among the variables selected to describe the epidemiology of the disease, the following categories: cutaneous clinical form, male patients, white ethnic group, and the age group of 20 - 39 years old were more affected than the others.

    The in situ detection of parasite antigens in tissue sections by immunohistochemistry (IHC) is a diagnostic alternative for human American tegumentary leishmaniasis (ATL), but has not been used for the diagnosis of cutaneous lesions in dogs with ATL. This study describes the results of IHC for the detection of amastigote forms and other Leishmania sp. antigen-positive cells and compares the results of IHC, histopathology and cytopathology for the diagnosis of canine ATL. In addition, possible cross-reactivity with sporotrichosis is analyzed. Forty paraffin-embedded biopsies and 40 smears of cutaneous lesions from dogs with ATL, confirmed by isolation and characterization of Leishmania (Viannia) braziliensis, and 40 paraffin-embedded biopsies of cutaneous lesions from dogs with sporotrichosis, confirmed by isolation of Sporothrix schenckii in culture (control group), were studied. Immunohistochemistry was more sensitive in detecting amastigote forms than cytopathology and histopathology, with a positivity rate of 70% (n=28) versus 37.5% and 22.5% for histopathology and cytopathology, respectively. Cytoplasmic staining of mononuclear and endothelial cells was detected by IHC, which was highly specific since no cytoplasmic staining of these cells or staining of fungal structures was observed in sporotrichosis fragments. In view of the higher sensitivity of IHC in detecting Leishmania sp. antigen and patterns of positivity for Leishmania sp. antigen compared to histopathology or cytopathology and the absence of cross-reactions with sporotrichosis, we recommend this technique for the diagnosis of canine tegumentary leishmaniasis. © The Author 2015.

    Phlebotominae sand flies have been involved as vectors of Leishmania. In Argentina, Nyssomyia neivai and Nyssomyia whitmani are involved as the main vectors of American Tegumentary Leishmaniasis (ATL). In the northeastern border of the country, an outbreak of ATL during 2004-2005 was associated with deforestation and subsequent settlement of farmers close to the edge of the forest. The aim of this work was to study the community composition of sand flies along time in farms located near primary and secondary forest in two environments: houses and pigsties. The association of abundance with temperature and precipitation was also evaluated for the most prevalent species. A total of 23,659 Phlebotominae belonging to the genera Nyssomyia, Migonemyia, Pintomyia, Evandromyia, Micropygomyia, Sciopemyia, Dampfomyia, Psathyromyia and Brumptomyia were captured. Ny. whitmani, which was the most abundant species, and Migonemyia migonei, which was the second most abundant species, were present throughout the year. Both species were positively associated with temperature, mostly up to 31-47 days, and with precipitation at 31 days before the sampling day. The abundance was higher in pigsties than in houses, but the time pattern was positively associated between both environments. These results confirm that Ny. whitmani is the dominant species in the study area and its presence throughout the year indicates a potential long period of ATL transmission. The presence of Mg. migonei as the second species in abundance is relevant, because it has been described as a secondary vector of the parasites of ATL and a putative vector of the agent of American Visceral Leishmaniasis. We discuss the role of the pigsty as the environment that attract more sandflies, taking into account the number of sand flies captured there, the distance from the home, and the association of sand fly abundance with each of the two environments.

    Full Text Available INTRODUCTION: American tegumentary leishmaniasis (ATL represents one of the most important public health issues in the world. An increased number of autochthonous cases of ATL in the Northeastern region of São Paulo State has been documented in the last few years, leading to a desire to determine the Leishmania species implicated. METHODS: PCR followed by DNA sequencing was carried out to identify a 120bp fragment from the universal kDNA minicircle of the genus Leishmania in 61 skin or mucosal biopsies from patients with ATL. RESULTS: DNA sequencing permitted the identification of a particular 15bp fragment (5' …GTC TTT GGG GCA AGT... 3' in all samples. Analysis by the neighbor-joining method showed the occurrence of two distinct groups related to the genus Viannia (V and Leishmania (L, each with two subgroups. Autochthonous cases with identity to a special Leishmania sequence not referenced in Genbank predominated in subgroup V.1, suggesting the possible existence of a subtype or mutation of Leishmania Viannia in this region. In the subgroup L.2, which showed identity with a known sequence of L. (L. amazonensis, there was a balanced distribution of autochthonous and non-autochthonous cases, including the mucosal and mucocutaneus forms in four patients. The last observation may direct us to new concepts, since the mucosal compromising has commonly been attributed to L. (V. braziliensis, even though L. (L. amazonensis is more frequent in the Amazonian region. CONCLUSIONS: These results confirm the pattern of distribution and possible mutations of these species, as well as the change in the clinical form presentation of ATL in the São Paulo State.

    Full Text Available American Tegumentary Leishmaniasis is caused by parasites of the genus Leishmania, and causes significant health problems throughout the Americas. In Panama, Leishmania parasites are endemic, causing thousands of new cases every year, mostly of the cutaneous form. In the last years, the burden of the disease has increased, coincident with increasing disturbances in its natural sylvatic environments. The study of genetic variation in parasites is important for a better understanding of the biology, population genetics, and ultimately the evolution and epidemiology of these organisms. Very few attempts have been made to characterize genetic polymorphisms of parasites isolated from Panamanian patients of cutaneous leishmaniasis. Here we present data on the genetic variability of local isolates of Leishmania, as well as specimens from several other species, by means of Amplified Fragment Length Polymorphisms (AFLP, a technique seldom used to study genetic makeup of parasites. We demonstrate that this technique allows detection of very high levels of genetic variability in local isolates of Leishmania panamensis in a highly reproducible manner. The analysis of AFLP fingerprints generated by unique selective primer combinations in L. panamensis suggests a predominant clonal mode of reproduction. Using fluorescently labeled primers, many taxon-specific fragments were identified which may show potential as species diagnostic fragments. The AFLP permitted a high resolution genetic analysis of the Leishmania genus, clearly separating certain groups among L. panamensis specimens and highly related species such as L. panamensis and L. guyanensis. The phylogenetic networks reconstructed from our AFLP data are congruent with established taxonomy for the genus Leishmania, even when using single selective primer combinations. Results of this study demonstrate that AFLP polymorphisms can be informative for genetic characterization in Leishmania parasites, at

    Juliana Aires

    Full Text Available BACKGROUND Maxadilan (Max is a salivary component in the sandfly Lutzomyia longipalpis (Lutz & Neiva 1912, a vector of visceral leishmaniasis. Max has a powerful vasodilatory effect and is a candidate vaccine that has been tested in experimental leishmaniasis. Nyssomyia neivai (Pinto 1926 is a vector of the pathogen responsible for American tegumentary leishmaniasis (ATL in Brazil. OBJECTIVE We searched for Max expression in Ny. neivai and for antibodies against Max in ATL patients. METHODS cDNA and protein were extracted from the cephalic segment, including salivary glands, of Ny. neivai and analysed by polymerase chain reaction, DNA sequencing, and blotting assays. The results were compared with data obtained from Lu. longipalpis samples. We quantified antibodies against Max in serum samples from 41 patients with ATL (31 and 10 with the cutaneous and mucocutaneous forms, respectively and 63 controls from the endemic northeastern region of São Paulo state, using enzyme-linked immunosorbent assay. FINDINGS Recognition of a Max-simile peptide by specific antibodies confirmed expression of a Max sequence in Ny. neivai (GenBank EF601123.1. Compared to controls, patients with ATL presented higher levels of antibodies against Max (p = 0.004; 24.4% of the patients with ATL and 3.2% of the controls presented anti-Max levels above the cutoff index (p = 0.014. The anti-Max levels were not associated with the specific clinical form of ATL, leishmanin skin test response, absence or presence of amastigotes in histopathologic exam, results of indirect immunofluorescence testing for leishmaniasis, or duration of cutaneous form disease. MAIN CONCLUSION High serum anti-Max levels did not protect patients against ATL, but confirmed previous natural exposure to Ny. neivai bites in this ATL endemic region.

    Full Text Available Abstract Background Interferon-gamma is a key cytokine in the protective responses against intracellular pathogens. A single nucleotide polymorphism (SNP located in the first intron of the human IFN-γ gene can putatively influence the secretion of cytokine with an impact on infection outcome as demonstrated for tuberculosis and other complex diseases. Our aim was to investigate the putative association of IFNG+874T/A SNP with American tegumentary leishmaniasis (ATL and also the influence of this SNP in the secretion of IFN-γ in vitro. Methods Brazilian ATL patients (78 cutaneous, CL, and 58 mucosal leishmaniasis, ML and 609 healthy volunteers were evaluated. The genotype of +874 region in the IFN-γ gene was carried out by Amplification Refractory Mutational System (ARMS-PCR. Leishmania-induced IFN-γ production on peripheral blood mononuclear cell (PBMC culture supernatants was assessed by ELISA. Results There are no differences between +874T/A SNP frequency in cases and controls or in ML versus CL patients. Cutaneous leishmaniasis cases exhibiting AA genotype produced lower levels of IFN-γ than TA/TT genotypes. In mucosal cases, high and low IFN-γ producers were clearly demonstrated but no differences in the cytokine production was observed among the IFNG +874T or A carriers. Conclusion Our results suggest that +874T/A polymorphism was not associated with either susceptibility or severity to leishmaniasis. Despite this, IFNG +874T/A SNP could be involved in the pathogenesis of leishmaniasis by influencing the amount of cytokine released by CL patients, although it could not prevent disease development. On the other hand, it is possible that in ML cases, other potential polymorphic regulatory genes such as TNF-α and IL-10 are also involved thus interfering with IFN-γ secretion.

    Full Text Available We report a case of an unusual presentation of American Tegumentary Leishmaniasis involving a male patient with a solitary lesion on the ear lobe, persisting with minimal increase for at least six months without ulceration or related symptoms. The histological sections showed epithelial atrophy and a large number of structures consistent with Leishmania sp. amastigotes within macrophages. Treatment commenced with meglumine antimoniate resulting in regression of the condition. This report is of importance given the unusual clinical manifestation and histopathological findings in this case and the fact that there was low correlation with the extended duration of the disease.Relatamos um caso de apresentação incomum de leishmaniose tegumentar americana com lesão solitária no lóbulo da orelha de um paciente do sexo masculino com mínimo aumento em, pelo menos, seis meses, sem ulceração ou sintomas relacionados. Os cortes histológicos mostraram atrofia epitelial e um grande número de estruturas compatíveis com amastigotas de Leishmania sp. no interior de macrófagos. O tratamento foi iniciado com antimoniato de meglumina, com regressão do quadro. A importância desse relato de caso é devido à apresentação clínica e histopatológica atípica e sua baixa correlação com a duração prolongada da doença.

    American cutaneous leishmaniasis has shown an endemic character in areas of North-North-west Paraná State, which were populated in 40's, where residual forests persist with intense modifications. The infection has been found mainly in males, but was found also in females and children and in many individuals of a same family. 513 cases of cutaneous leishmaniasis notified to SUCAM by clinical diagnosis were investigated. Treatment was begun with Glucantime at State Health Centers or at SUCAM. Of 513 treated patients 260 (50.67%) were considered clinically cured. The remaining 253 (49.33%) abandoned treatment. The quantity of Glucantime supplied to the patients varied from 10 vials to more than 200, with or without intervals during the treatment. Two hundred and seventeen (85.46%) patients among 260 received from 10 to 75 vials. The occurrence of leishmaniasis in 163 (31.75%) women and in 34 (6.62%) children, of both sexes, up to 10 years old, suggests domiciliary transmission. It's not known if the 253 (49.33%) individuals who abandoned the treatment recovered. This high number shows the necessity of better knowledge of the consequences that can occur due to incomplete treatment.

    BACKGROUND American tegumentary leishmaniasis (ATL) is a non-lethal parasitic disease that presents with cutaneous (CL) and mucosal (ML) clinical forms. ATL treatment aims at healing the lesions and preventing the development of the late mucosal form. Systemic meglumine antimoniate (MA) therapy with 10-20 mg Sb5+/kg/day is the first choice of treatment. However, alternative therapies using 5 mg Sb5+/kg/day or intralesional (IL) MA are the usual regimens at the National Institute of Infectious Diseases (NIID), Rio de Janeiro, Brazil. OBJECTIVES To evaluate lethality and the incidence of relapse and development of late ML in CL patients treated at NIID from 2001 until 2013. METHODS Data were recovered from records of all ATL patients diagnosed during that period. FINDINGS Out of 777 patients, 753 were treated with MA (96.9%). Of those, 89.1% received alternative therapy of 9.9% IL and 79.2% systemic 5 mg Sb5+/kg/day. Some patients required 1-3 additional courses of treatment, thus making a total of 997 courses; 85.2% of them were subjected to alternative therapies. Lethality was 0.1%, relapse incidence 5.8%, and late ML incidence 0.25%. As a final outcome for the 777 patients, 95.9% were cured, 0.1% died and 4.0% were not able to follow-up. MAIN CONCLUSIONS Alternative MA schedules resulted in low lethality without increase of relapse or late ML incidence. PMID:29211245

    = 1). Only Ps. ayrozai possessed a sequence similar to that of L. (V.) guyanensis (99%). Through microscopic analysis, five specimens of Ev. saulensis were found to possess flagellate forms in the hindgut, with an infection rate of 2.4%. Samples from 33 fed females were submitted to cytb gene amplification, for which sequencing determined that all were similar to the sequence deposited on GenBank for Gallus gallus (domestic chicken). The high abundance of Trichophoromyia auraensis and Ev. saulensis, and the detection of L. (V.) braziliensis DNA, suggests that both species may be vectors of American tegumentary leishmaniasis. Psychodopygus ayrozai was found to be infected by L. (V) braziliesnsis and L. (V.) guyanensis, and although collected in low abundance, it may be a potential vector in the region. The sand fly fauna was found to be rich and diverse with predominance of the genus Psychodopygus. Identification of food sources of fed females showed that 100% amplified a gene region compatible with the domestic chicken, which although considered refractory in the disease transmission cycle, may have an influence on the population dynamics of sand flies.

    Full Text Available American tegumentary leishmaniasis is endemic to the Espírito Santo State, Brazil, where it is widely distributed. The composition of the phlebotomine sand fly fauna in an American tegumentary leishmaniasis focus was determined by monthly sampling, using Shannon light traps in an Atlantic Forest reserve and adjacent habitat that had been modified by human activity. Seasonal fluctuations in numbers of the most abundant species were also monitored from June 2004 to May 2006. Of the 6,176 specimens collected, 47.4% were captured in the forest and 52.6% in the disturbed habitat. Although Lutzomyia davisi (60.8% predominated in specimens from the forest, those captured near human dwellings consisted almost entirely of Lu. choti (72% and Lu. intermedia (24.3%. All three species occurred throughout the year. Based on our findings, Lu. intermedia probably acts as the principal domestic Leishmania vector in the study area.A leishmaniose tegumentar americana é endêmica e amplamente distribuída no Estado do Espírito Santo, Brasil.

Foram capturados 6.176 espécimes, dos quais 47,4% ocorreram no ambiente florestal e 52,6%, no ambiente antrópico. Lutzomyia davisi (60,8% predominou no ambiente florestal e Lu. choti (72% seguida de Lu. intermedia (24,3% predominaram no ambiente antrópico. As três espécies ocorreram ao longo de todo o ano. Os dados indicam que Lu. intermedia provavelmente atue como principal vetor domiciliar de Leishmania na área de estudo.

PCR showed 92.3% sensitivity, 93.3% specificity, a 99.2% positive predictive value and a 13.84 positive likelihood ratio. In the NDEF group, PCR confirmed ATL in 13 of the 23 patients, seven of whom responded to leishmaniasis treatment and six who presented spontaneous healing of the lesion. PCR should be included in the routine diagnostic procedures for ATL, especially for cases found to be negative by conventional methods.

    The diagnosis of drug-resistant tuberculosis (DR-TB) in children is challenging and treatment is associated with many adverse effects. We aimed to assess if careful observation, without initiation of second-line treatment, is safe in asymptomatic children referred with 'culture-confirmed' DR-TB. KwaZulu-Natal, South Africa-an area with high burdens of HIV, TB and DR-TB. We performed an outcome review of children with 'culture-confirmed' DR-TB who were not initiated on second-line TB treatment, as they were asymptomatic with normal chest radiographs on examination at our specialist referral hospital. Children were followed up every other month for the first year, with a final outcome assessment at the end of the study. In total, 43 asymptomatic children with normal chest radiographs were reviewed. The median length of follow-up until final evaluation was 549 days (IQR 259-722 days); most (34; 83%) children were HIV uninfected. Resistance patterns included 9 (21%) monoresistant and 34 (79%) multidrug-resistant (MDR) strains. Fifteen children (35%) had been treated with first-line TB treatment, prior to presentation at our referral hospital. At the final evaluation, 34 (80%) children were well, 7 (16%) were lost to follow-up, 1 (2%) received MDR-TB treatment and 1 (2%) died of unknown causes. The child who received MDR-TB treatment developed new symptoms at the 12-month review and responded well to second-line treatment. Bacteriological evaluation should not be performed in the absence of any clinical indication. If drug-resistant Mycobacterium tuberculosis is detected in an asymptomatic child with a normal chest radiograph, close observation may be an appropriate strategy, especially in settings where potential laboratory error and poor record keeping are constant challenges.

    Paracoccidioidomycosis (PCM) is a systemic mycosis, endemic in most Latin American countries, especially in Brazil. It is caused by the thermo-dimorphic fungus of the genus Paracoccidioides (Paracoccidioides brasiliensis and Paracoccidioides lutzii). Innate immune response plays a crucial role in host defense against fungal infections, and neutrophils (PMNs) are able to combat microorganisms with three different mechanisms: phagocytosis, secretion of granular proteins, which have antimicrobial properties, and the most recent described mechanism called NETosis. This new process is characterized by the release of net-like structures called Neutrophil Extracellular Traps (NETs), which is composed of nuclear (decondensed DNA and histones) and granular material such as elastase. Several microorganisms have the ability of inducing NETs formation, including gram-positive and gram-negative bacteria, viruses and some fungi. We proposed to identify NETs in tegumentary lesions of patients with PCM and to analyze the interaction between two strains of P. brasiliensis and human PMNs by NETs formation in vitro. In this context, the presence of NETs in vivo was evidenced in tegumentary lesions of patients with PCM by confocal spectrum analyzer. Furthermore, we showed that the high virulent P. brasiliensis strain 18 (Pb18) and the lower virulent strain Pb265 are able to induce different patterns of NETs formation in vitro. The quantification of extracellular DNA corroborates the idea of the ability of P. brasiliensis in inducing NETs release. In conclusion, our data show for the first time the identification of NETs in lesions of patients with PCM and demonstrate distinct patterns of NETs in cultures challenged with fungi in vitro. The presence of NETs components both in vivo and in vitro open new possibilities for the detailed investigation of immunity in PCM.

    Among approximately 190 species of Lutzomyia in Peru, only a small number have been identified as vectors of tegumentary leishmaniasis in Western and inter-Andean valleys. These include L. peruensis, L. verrucarum, L. tejadai, L. ayacuchensis, and L. pescei. In the Amazon region, L. yuilli yuilli, L. chagasi, L. davisi, and L. auraensis are naturally infected, among the subgenera Leishmania and Viannia. L. auraensis is newly reported as a potential vector of leishmaniasis in neotropical regions. Among the primary and most widely distributed vectors of human bartonellosis or Carrión's disease, L. verrucarum and L. peruensis are predominant in the Andean regions of northern, central, and southern Peru. Other potential vectors of Carrion's disease are L. serrana in the Monzon Valley, Huamalies, and Huanuco; L. pescei in Apurímac and Cusco; and L. robusta and L. maranonensis in Jaén, San Ignacio, and Utcubamba provinces, and the high forests of Peru. Because of the high prevalence of leishmaniasis and bartonellosis outside of known endemic areas in Peru, it is necessary to update data and distribution maps of these disease vectors. This may improve both prevention and control measures. Existing information about sandfly vectors in Peru is also provided in this article.

    Lyme disease patients with erythema migrans are said to have post-treatment Lyme disease symptoms (PTLDS) if there is persistence of subjective symptoms for at least 6 months following antibiotic treatment and resolution of the skin lesion. The purpose of this study was to characterize PTLDS in patients with culture-confirmed early Lyme disease followed for >10 years. Adult patients with erythema migrans with a positive skin or blood culture for Borrelia burgdorferi were enrolled in a prospective study beginning in 1991 and followed up at 6 months and annually thereafter to determine the long-term outcome of this infection. The genotype of the infecting strain of B. burgdorferi was evaluated in subjects with PTLDS. One hundred twenty-eight subjects with culture-confirmed early Lyme disease, of whom 55% were male, were followed for a mean ± SD of 14.98 ± 2.71 years (median = 15 years; range = 11-20 years). Fourteen (10.9%) were regarded as having possible PTLDS, but only 6 (4.7%) had PTLDS documented at their last study visit. Nine (64.3%) had only a single symptom. None of the 6 with PTLDS at their last visit was considered to be functionally impaired by the symptom(s). PTLDS was not associated with a particular genotype of B. burgdorferi. PTLDS may persist for >10 years in some patients with culture-confirmed early Lyme disease. Such long-standing symptoms were not associated with functional impairment or a particular strain of B. burgdorferi. © The Author 2015.

    This study evaluated the occurrence of American tegumentary leishmaniasis (ATL) in the State of Amazonas, Brazil, in the last 30 years with emphasis on the last 10 years (2001 to 2010). The disease was predominantly observed in males (76.2%), in the 21- to 30-year-old age group (26.6%) and in extractive workers (43.7%); 3.3% of the cases were the mucosal form. The endemic channel shows the disease seasonality, with a predominance of cases at the beginning and end of each year. The number of cases by municipality in the period of 2001-2010 shows the maintenance of the endemic in the localities where the highest numbers of cases have always been registered, namely, Manaus, Rio Preto da Eva, Itacoatiara and Presidente Figueiredo. The comparison of data from 2001 to 2005 and from 2006 to 2010 showed the emergence of this disease in municipalities that had been previously unaffected. In the last years, there has been a significant increase in the activities of control, diagnosis and treatment of leishmaniasis in the State of Amazonas. In conclusion, the historical series of ATL analyzed in this study suggests that the transmission foci remain and are even expanding, though without continuous transmission in the intra- or peridomicile settings. Moreover, the disease will persist in the Amazon while the factors associated with infection acquisition relative to forest exploitation continue to have economic appeal. There is a real expectation of wide variations in disease incidence that can be influenced by climate and economic aspects.

    Human tegumentary leishmaniasis (HTL), characterized by skin ulcers that may spread and cause dreadful and massive tissue destruction of the nose and mouth, is considered a neglected tropical disease, and it is a serious threat to global health due to its continuous expansion, favored by the lifecycle of its causative organism that is maintained in domestic animal reservoirs and anthropophilic sand fly species. Serodiagnosis of HTL is a great challenge due to many biological factors, including hampered specificity and/or sensitivity. This investigation addresses the unmet need for new diagnostic markers of HTL, and describes a simple platform to improve the serodiagnosis. A constrained conformational phage display random peptide library combined with a magnetic microsphere-based subtraction strategy was used to identify ligands with potential diagnostic applications. Six clones were selected against IgG antibodies from HTL patients, characterized by sequencing and confirmed by a phage-ELISA using sera from patients developing visceral leishmaniasis (n=20), Chagas disease (n=10), mucosal (n=30) and cutaneous (n=20) leishmaniasis; as well as from healthy subjects living in endemic (n=20) and non-endemic (n=30) areas of leishmaniasis. A wild-type M13-phage clone and a soluble Leishmania antigenic extract were used as negative and positive controls, respectively. Three clones reached 100% sensitivity and specificity, without any cross-reactivity with sera from patients with leishmaniasis-related diseases. Briefly, we describe for the first time a set of serological markers based on three immunodominant mimotopes that showed 100% accuracy, and that could be used in a phage-ELISA assay for the HTL serodiagnosis.

    To propose a new operational unit in the locality scale capable of subsidizing the construction of an information system to control the transmission of tegumentary leishmaniasis at this scale, in a region of high endemicity of the Atlantic Forest. We examined the adequacy of data and instruments in an area of high endemicity in the Atlantic Forest located in the South of the State of Rio de Janeiro from 1990 to 2012. The study proposed an operational unit called Local Surveillance Unit to make all used databases compatible by adjusting census sectors. This enabled the overlap and comparison of information in different periods. The spreading process of the transmission of tegumentary leishmaniasis in the Baía da Ilha Grande region does not depend on great population movements, and can occur in areas with population growth or decrease. The data information system allowed the adequate identification and characterization of the place of residence. We identified relevant characteristics of the place of transmission, such as self-limited in time and not associated with recent deforestation. The results also highlight the lack of synchronicity in the case production in territorial units involved in the endemic-epidemic process, noting that this process is in constant motion. The transmission process seems more connected to the presence and movement of rodents that move continuously in the region than to the local density of vectors or the permanence of infected dogs at home. New control strategies targeted at the foci of transmission must be considered. The construction of a new operational unit, called Local Surveillance Unit, was instrumental in the endemic-epidemic process analysis.

    The HIV epidemic increased the burden of tuberculosis (TB) in sub-Saharan Africa. We evaluated the impact that scaling-up of the public-funded antiretroviral treatment (ART) program had on incidence of hospitalization for culture-confirmed and overall-TB in HIV-infected and HIV-uninfected children from 2005 to 2009. The study was undertaken in Soweto, South Africa, where ART coverage of HIV-infected children increased from 43% in 2005 to 84% by 2009. Trends in incidence of hospitalization for clinically diagnosed and culture-confirmed TB in children 3 months to The incidence (per 100,000) of culture-confirmed TB declined by 63.1% from 2005 (69.8) compared with 2009 (25.8; P The month-by-month rate of decline of culture-confirmed TB was 2.3% in HIV-infected and 1.1% in HIV-uninfected children over the study period. The residual burden of TB remained 42-fold greater in HIV-infected children, 78% of whom were severely immune compromised, compared with HIV-uninfected children by 2009. Increase in ART coverage was associated with significant decline in TB hospitalizations in HIV-infected children. This reduction may also in part have been due to reduced Mycobacterium tuberculosis transmission resulting from increased ART access among HIV-infected adults, which may have contributed to the reduction of culture-confirmed TB in HIV-uninfected children.

    Full Text Available Antimony compounds are the cornerstone treatments for tegumentary leishmaniasis. The reactivation of herpes virus is a side effect described in few reports. We conducted an observational study to describe the incidence of herpes zoster reactivation during treatment with antimony compounds. The global incidence of herpes zoster is approximately 2.5 cases per 1,000 persons per month (or 30 cases per 1,000 persons per year. The estimated incidence of herpes zoster in patients undergoing antimony therapy is higher than previously reported.

    Full Text Available The existence of a number of different species of Leishmania, the persistent increase in the infection rate of diseases caused by this parasite (tegumentary and visceral forms, the different epidemiological situations found in regions of both recent and older colonization, and the trend towards urbanization have led to the adoption of different strategies to control leishmaniases in Brazil. The control measures involve studies related to the parasite, vectors, sources of infection (animal and human, clinical aspects, geographical distribution, historical and socioeconomic factors, integration of health services, and adequate technologies for diagnosis, treatment, and immunoprophylaxis. Finally, successful control requires work with human communities, involving education, provision of information, health promotion, and participation of these communities in the planning, development, and maintenance of control programs.

    Full Text Available The aim of this study was to characterize clinical field isolates of Leishmania spp. obtained from patients with American Tegumentary Leishmaniasis (ATL who live in Goiás state, Brazil. The presumed areas of infection were in Goiás, Tocantins, and Pará states. Three isolates of parasites were identified as L. (Viannia braziliensis and one as L. (V. guyanensis. The in vitro growth profiles were found to be similar for all parasites. Nevertheless, in C57BL/6 mice, L. (V. guyanensis infection was better controlled than L. (V. braziliensis. Yet in C57BL/6 mice deficient in interferon gamma, L. (V. guyanensis lesions developed faster than those caused by L. (V. braziliensis isolates. In BALB/c mice, the development of lesions was similar for isolates from both species; however, on the 11th week of infection, amastigotes could not be observed in macrophages from L. (V. guyanensis-infected mice. Thus, L. (V. guyanensis can be circulating in Goiás, a state where autochthonous cases of this species had not yet been reported. Considering the difficulties to differentiate L. (V. guyanensis from L. (V. braziliensis at the molecular, morphological, and clinical (human and murine models levels, the presence of L. (V. guyanensis infections is possibly underestimated in several regions of Brazil.

    Exposure to Leishmania induces a humoral immune response that can be used as a marker of parasite exposure. Herein, ELISA was used to screen sera from patients with Tegumentary Leishmaniasis (TL) against different L. infantum-chagasi-derived recombinant proteins (rHSP70, rH2A, rH2B, rH3, rH4 and rKMP11). Among the recombinant proteins, rHSP70 and rH2A showed the best reactivity against human sera obtained from endemic areas of TL. Receiver-Operator Characteristics (ROC) curve analysis was used to identify the effectiveness of these proteins for serodiagnosis of TL. ROC curves confirmed the superior performance of rHSP70 and rH2A, in comparison to the other tested recombinant proteins. Additionally, we evaluated the specificity of the response to rHSP70 and rH2A by testing sera obtained from patients with Chagas' disease, Tuberculosis, Leprosy or Systemic Lupus Erythematosus. In this case, rHSP70 displayed an increased ability to discriminate diseases, in comparison to SLA. Our results raise possibility of using rHSP70 for the serodiagnosis of TL.

    Full Text Available Las Lomitas, Formosa, Argentina, reported 96 cases of tegumentary leishmaniasis during 2002. The urban transmission was suggested although previous outbreaks were related with floods of the Bermejo river (BR 50 km from the village. Phlebotomine collections were performed during March 2002 to define the spatial distribution of risk, together with satellite imaginery. The phlebotomine/trap obtained was 1679.5 in the southern BR shore, 1.1 in the periruban-rural environment and 2.3 in the northern Pilcomayo river marshes. Lutzomyia neivai was the prevalent species (91.1% among the 2393 phlebotomine captured, and it was only found in the BR traps. The other species were L. migonei (7.9%, L. cortelezzii (0.9%, and Brumptomyia guimaraesi (0.1%. The satellite images analysis indicates that the fishing spots at the BR were significantlyoverflowed during the transmission peak, consistent with fishermen recollections. This spatial restricted flood might concentrate vectors, reservoirs, and humans in high places. Therefore, both the spatial distribution of vectors and the sensor remoting data suggests that in Las Lomitas area the higher transmission risk it is still related with the gallery forest of the BR, despite of the urban residence of the cases. The surveillance and control implications of these results are discussed.

    Experimental vaccine candidates have been evaluated to prevent leishmaniasis, but no commercial vaccine has been proved to be effective against more than one parasite species. LiHyT is a Leishmania-specific protein that was firstly identified as protective against Leishmania infantum. In this study, LiHyT was evaluated as a vaccine to against two Leishmania species causing tegumentary leishmaniasis (TL): Leishmania major and Leishmania braziliensis. BALB/c mice were immunized with rLiHyT plus saponin and lately challenged with promastigotes of the two parasite species. The immune response generated was evaluated before and 10 weeks after infection, as well as the parasite burden at this time after infection. The vaccination induced a Th1 response, which was characterized by the production of IFN-γ, IL-12 and GM-CSF, as well as by high levels of IgG2a antibodies, after in vitro stimulation using both the protein and parasite extracts. After challenge, vaccinated mice showed significant reductions in their infected footpads, as well as in the parasite burden in the tissue and organs evaluated, when compared to the control groups. The anti-Leishmania Th1 response was maintained after infection, being the IFN-γ production based mainly on CD4(+) T cells. We described one conserved Leishmania-specific protein that could compose a pan-Leishmania vaccine. © 2016 John Wiley & Sons Ltd.

METHODOLOGY/PRINCIPAL FINDINGS: Herein, ELISA was used to screen sera from patients with Tegumentary Leishmaniasis (TL against different L. infantum-chagasi-derived recombinant proteins (rHSP70, rH2A, rH2B, rH3, rH4 and rKMP11. Among the recombinant proteins, rHSP70 and rH2A showed the best reactivity against human sera obtained from endemic areas of TL. Receiver-Operator Characteristics (ROC curve analysis was used to identify the effectiveness of these proteins for serodiagnosis of TL. ROC curves confirmed the superior performance of rHSP70 and rH2A, in comparison to the other tested recombinant proteins. Additionally, we evaluated the specificity of the response to rHSP70 and rH2A by testing sera obtained from patients with Chagas' disease, Tuberculosis, Leprosy or Systemic Lupus Erythematosus. In this case, rHSP70 displayed an increased ability to discriminate diseases, in comparison to SLA. CONCLUSION: Our results raise possibility of using rHSP70 for the serodiagnosis of TL.

    DNA hybridisation, using probes labelled with 32 P, was used to type Leishmania samples isolated from patients living in endemic areas of Mato Grosso State (Brazil), and clinically diagnosed as having tegumentary leishmaniasis. k DNA cloned mini-circle probes specific for the Leishmania mexicana and Leishmania braziliensis complexes were used. The results showed that L. braziliensis is the predominant group infecting human patients in the state. Sixty-eight samples were typed, 64 samples (94.1%) belonging to the L. braziliensis complex and only four (5.9%) belonging to the L. mexicana complex. Accurate identification of the Leishmania permits better orientation of the medical follow-up, since clinical manifestations may vary depending on the complex to which the parasite belongs. The epidemiological information furnished by the identification of the Leishmania in given endemic area is also essential for the design of appropriate control measures. (author)

    Full Text Available In South America, various species of Leishmania are endemic and cause New World tegumentary leishmaniasis (NWTL. The correct identification of these species is critical for adequate clinical management and surveillance activities. We developed a real-time polymerase chain reaction (PCR assay and evaluated its diagnostic performance using 64 archived parasite isolates and 192 prospectively identified samples collected from individuals with suspected leishmaniasis enrolled at two reference clinics in Lima, Peru. The real-time PCR assay was able to detect a single parasite and provided unambiguous melting peaks for five Leishmania species of the Viannia subgenus that are highly prevalent in South America: L. (V. braziliensis, L. (V. panamensis, L. (V. guyanensis, L. (V. peruviana and L. (V. lainsoni. Using kinetoplastid DNA-based PCR as a gold standard, the real-time PCR had sensitivity and specificity values of 92% and 77%, respectively, which were significantly higher than those of conventional tests such as microscopy, culture and the leishmanin skin test (LST. In addition, the real-time PCR identified 147 different clinical samples at the species level, providing an overall agreement of 100% when compared to multilocus sequence typing (MLST data performed on a subset of these samples. Furthermore, the real-time PCR was three times faster and five times less expensive when compared to PCR - MLST for species identification from clinical specimens. In summary, this new assay represents a cost-effective and reliable alternative for the identification of the main species causing NWTL in South America.

Sand fly distribution in time and space suggests that in the province of Misiones (1 the species already present before 1990 could give rise to the epidemic by the density/dispersion fluctuation of their local populations; (2 the abundance of L. intermedia s. l. was associated with environments with ecotones of primary-secondary vegetation, close to water bodies and with moderate human disturbance; (3 this species showed, towards the end of 1997, peaks of exceptional abundance, subsequent to rainfall peaks in 1996. This increase in abundance of potential vector sand fly populations close to houses with colonizable surroundings could have generated the 1998 epidemic outbreak.

    Full Text Available ABSTRACT Bacillary angiomatosis (BA is an angioproliferative disease of immunocompromised patients that usually presents as vascular tumors in the skin and subcutaneous tissues. It is caused by chronic infections with either Bartonella henselae or B. quintana. Oral cavity BA is exceedingly rare and even rarer without simultaneous cutaneous disease. We report herein the case of a 51-year-old HIV-infected man who presented severe odynophagia and an eroded lesion on the hard palate that progressed to an oronasal fistula. No cutaneous lesions were recorded. Doxycycline led to complete resolution. To the best of our knowledge, only six previous cases of oral BA without tegumentary disease have been previously reported and none of them progressed to fistula.

    Full Text Available The existence of a number of different species of Leishmania, the persistent increase in the infection rate of diseases caused by this parasite (tegumentary and visceral forms, the different epidemiological situations found in regions of both recent and older colonization, and the trend towards urbanization have led to the adoption of different strategies to control leishmaniases in Brazil. The control measures involve studies related to the parasite, vectors, sources of infection (animal and human, clinical aspects, geographical distribution, historical and socioeconomic factors, integration of health services, and adequate technologies for diagnosis, treatment, and immunoprophylaxis. Finally, successful control requires work with human communities, involving education, provision of information, health promotion, and participation of these communities in the planning, development, and maintenance of control programs.A ocorrência de várias espécies de Leishmania, o contínuo aumento das afecções causadas por esses parasitas (formas tegumentares e visceral e as diferentes situações epidemiológicas encontradas, tanto em regiões de colonização recente quanto de colonização antiga, com tendência a urbanização, vem requerendo a adoção de diferentes estratégias para o controle dessas endemias no Brasil.

    To contribute to the knowledge of the role of small mammals in the transmission cycle of tegumentary leishmaniasis caused by Leishmania braziliensis, we studied the small mammal community and its temporal and spatial association with phlebotominae, as well as small mammal infection by Leishmania spp. by PCR-RFLP analyses in an endemic area of northeastern Argentina. Ten small mammal samplings were conducted (2007-2009, 7506 Sherman trap nights and 422 cage trap nights). In two of these samplings, 16 capture stations each one consisting of a CDC light trap to capture phlebotominae, two to four Sherman traps and two cage traps were placed. We found co-occurrence of phlebotominae and small mammal captures in four stations, which were all the stations with small mammal captures and yielded 97% (2295 specimens, including 21 gravid females) of the total phlebotominae captures, suggesting that small mammals may provide a potential source of blood for phlebotominae females. One Didelphis albiventris and two Rattus rattus were associated with high captures of Nyssomyia whitmani, vector of L. braziliensis in the study area. The PCR-RFLP analyses confirm the presence of L. braziliensis in two sigmodontine small mammals (Akodon sp. and Euryoryzomys russatus) for the first time in Argentina, to our knowledge.

Leishmaniasis is caused by several species of protozoa of the genus Leishmania. The evolution of the pathology and the resolution of the leishmaniasis are dependent mainly on the Leishmania species involved, although the cytokine profile plays an important role in the development of the immune response. OBJECTIVES: The purpose of our study was to evaluate the immune response of patients affected by lesions of cutaneous leishmaniasis by immunostaining of the OX40, CD20, IFN-γ and IL-4 proteins. METHODS: The tissue samples were collected from indolent skin ulcers confirmed as cutaneous leishmaniasis of 41 patients aged between six and 90 years. The lesions were submitted to OX40, CD20, INF-γ and IL-4 immunolabeling. RESULTS: We observed a statistically significant higher expression of IFN-γ compared with IL-4 (p=0.009.

  6. American = Independent?

    Science.gov (United States)

    Markus, Hazel Rose

    2017-09-01

    U.S. American cultures and psyches reflect and promote independence. Devos and Banaji (2005) asked, does American equal White? This article asks, does American equal independent? The answer is that when compared to people in East Asian or South Asian contexts, people in American contexts tend to show an independent psychological signature-a sense of self as individual, separate, influencing others and the world, free from influence, and equal to, if not better than, others (Markus & Conner, 2013). Independence is a reasonable description of the selves of people in the White, middle-class American mainstream. Yet it is a less good characterization of the selves of the majority of Americans who are working-class and/or people of color. A cultural psychological approach reveals that much of North American psychology is still grounded in an independent model of the self and, as such, neglects social contexts and the psychologies of a majority of Americans. Given the prominence of independence in American ideas and institutions, the interdependent tendencies that arise from intersections of national culture with social class, race, and ethnicity go unrecognized and are often misunderstood and stigmatized. This unseen clash of independence and interdependence is a significant factor in many challenges, including those of education, employment, health, immigration, criminal justice, and political polarization.

Alexey Efimov - Corresponding Member of the USSR Academy of Sciences since 1938, Head of the Department of Modern and Contemporary History and Dean of the Historical School at the Moscow State University - one of the first professors of the Faculty of International Relations MGIMO. Efimov distinguished himself by a broad vision and scope of scientific interests. Back in 1934 he published a monograph "On the history of capitalism in the United States," which initiated a series of research culminating in the fundamental work "The United States. The path of capitalist development (pre-imperialist era". Alexey was not only a great scientist but also a great teacher, whose lectures was popular throughout Moscow. His lecture courses, given at the end of the 1940s at MGIMO, became the basis for the first post-war history textbooks USA - "Essays on the history of the United States." At least as colorful a figure was Professor Leo Izrailevich Zubok - a man of unusual destiny. As a teenager he emigrated to the United States with his parents, where he soon joined the American revolutionary movement in the 1920s and was forced to leave the country. He came to MGIMO being already an experienced scientists. His research interests were very wide: from the study of American foreign policy expansion to the history of the labor movement in the United States. Zubok's fundamental works still have not lost its scientific significance. He has successfully combined scientific work with teaching. Tutorials that are based on his lectures were very popular not only among students of MGIMO.

The information carries certain meanings that have important outcomes thus defining the power of a given nation. Foreign policy is the channel through which global politics is exercised. International politics is a hierarchy of power being determined by important cultural, economic as well as geographical aspects. The reasons and strategies that are used in order to reach the outcomes in global politics represent the focus of the present paper. The United States has been the leader in international politics since the early 20th century due to its vast resources and wealth as well as its cultural output. America’s interest in preserving a democratic and free world has its foundation in the beliefs and values it stands for the aim of this paper is to question whether or not there is a concrete premise for the idea of American exceptionalism.

    The Biofire meningitis/encephalitis panel is a PCR with fourteen targets including Cryptoccocus neoformans/gattii. Its rapid results may allow clinicians to confirm a diagnosis within a relatively short time. However, false negative results secondary to erroneous automated reading, and false positive results have been reported. We report two cases of Cryptococcus meningitis with negative results on the Biofire ME panel, due to a fungal load below the limit of detection. Copyright © 2018. Published by Elsevier Ltd.

  11. Laboratory Mill for Pulverizing and Homogenizing Nail Specimens as an Aid to Microscopy and Culture Confirmation of Onychomycosis

    Luedemann, George M.; LeBreton, Ernest

    1972-01-01

    A small mill has been developed for reducing nail clippings to a convenient size for microscopy and inoculation onto isolation media. The milling process acts to pulverize and homogenize the specimen. The use of a homogeneous sample in microscopy increases the opportunity for the discovery of fungal hyphae in a specimen. The use of a pulverized specimen increases the possibility of culture isolation by permitting greater numbers of potentially viable fungal cells to come into direct contact with the isolation medium.

    Newhouse, Andrew E; Schrodt, Franziska; Maynard, Charles A; Powell, William A

    2006-01-01

    American elm (Ulmus americana) is a valuable and sentimental tree species that was decimated by Dutch elm disease in the mid-20th century. Therefore, any methods for modifying American elm or enhancing disease resistance are significant. This protocol describes transformation and tissue culture techniques used on American elm. Leaf pieces containing the midvein and petiole are used for explants. Agrobacterium tumefaciens strain EHA105 is used for transformation, with the binary vector pSE39, containing CaMV35S/nptII as a selectable marker, ACS2/ESF39A as a putative resistance enhancing gene, and CaMV35S/GUS as a reporter.

    The American Dental Dream-the cultural desire for straight, white teeth-is difficult, if not impossible, for poor and working-class people to achieve. Using ethnographic fiction, autoethnography, poetry, and qualitative interviewing, I brush away the taken-for-granted assumptions about teeth. I explore the personal, relational, and structural consequences of this cultural desire, and show how social class writes itself on our bodies. I write these culture-centered teeth tales to show how one might cope with their teeth.

  16. American Nations, Latin States

    Directory of Open Access Journals (Sweden)

    Jorge Nelson Ahumada

    2016-02-01

    Full Text Available The nation, as artifact of modernity, assumes particularities in America such as the colonization and genocide of original peoples which still weighs as a never ending comeback. Nevertheless, capital, with its overwhelming force, destroyed peoples, cultures, traditions and landscapes. Latin America faces the challenge of uniting beyond the necessities of capital, and beyond two languages, spanish and portuguese. All of which has full validity at present with the blocks UNASUR and ALBA. Ethnocentricity is postulated as the exclusive condition of all possible humanity and, as programme, racism without races; Latin American miscegenation, as the potential for unity and the strength of emancipation as a project. Our intellectuals, who constructed a unique and superlative literature, are the lighthouses in the development of a nationalism without races. Anthropology in debate with psychoanalysis can become a compass in rethinking our America.

    2007-12-01

    While a foundation of German scientific methods enabled the rapid growth of North American Astronomy in the nineteenth century, during the seventeenth and most of the eighteenth centuries, the colonial men of science looked only to the English mother country for scientific patronage and guidance. An essay on fundamental astronomy appeared in one of the annual colonial almanacs as early as 1656, telescopic observations were made about 1660 and the first original colonial astronomical work was published by Thomas Danforth on the comet of 1664. By 1671 the Copernican ideas were so espoused at Harvard College that a physics class refused to read a Ptolemaic textbook when it was assigned to them by a senior instructor. At least in the Cambridge-Boston area, contemporary colonialist had access to the most recent scientific publications from the mother country. Observations of the great comet of 1680 by the Almanac maker, John Foster, reached Isaac Newton and were used and gratefully acknowledged in his Principia. During the seventeenth century the colonial interest in astronomy was more intense than it was for other sciences but colonists still occupied a position in the scientific backwater when compared with contemporary European scientists. Nevertheless, the science of astronomy was successfully transplanted from England to North America in the seventeenth century.

    Panciera, R J; Ewing, S A

    2003-06-01

    American canine hepatozoonosis is an emerging, tick-transmitted infection of domestic dogs caused by a recently recognized species of apicomplexan parasite, Hepatozoon americanum. The known definitive host of the protozoan is the Gulf Coast tick, Amblyomma maculatum. Presently recognized intermediate hosts include the domestic dog and the coyote, Canis latrans. Laboratory-reared larval or nymphal A. maculatum can be infected readily by feeding to repletion on a parasitemic intermediate host; sporogony requires 35-40 days. Transmission of infection to the dog has been produced experimentally by oral administration of mature oocysts or oocyst-containing ticks. Canine disease follows experimental exposure in 4-6 weeks and is characterized by systemic illness, extreme neutrophilic leukocytosis, muscle and bone pain, and proliferation of periosteal bone. Histopathological findings include multifocal skeletal and cardiac myositis associated with escape of mature merozoites from within the host-cell environment. There is also rapid onset of periosteal activation and osteogenesis and, less frequently, glomerulopathy and amyloidosis. Sequential stages of development of H. americanum in both the dog and the tick have been elucidated. Gamonts potentially infectious to ticks have been observed in peripheral blood leukocytes of the dog in as few as 28 days after exposure to oocysts. Young coyotes experimentally exposed to a canine strain of H. americanum acquired disease indistinguishable from that of similarly exposed young dogs.

    North America is an energy community fortunate to be endowed with a rich and varied resource base. It consumes about a third of the world's energy and produces about one quarter of world energy supply. North America depends on a mix of complementary energy sources that should remain competitive but not in conflict. The current supply mix varies between Canada, the United States and Mexico, but fossil fuels are dominant across the region, leaving the three member countries vulnerable to a myriad of risks associated with traditional supply sources. Energy trade between all three countries is also a major contributor to the region's economy. Thus, the impetus for collaboration across the region has grown out of the common goals of energy security and economic prosperity. The goal of the WEC regional group was to discuss avenues for advancing North American cooperation and coordination on a range of energy issues. An additional objective was to develop policy recommendations that will facilitate effective development and use of the region's energy resources. Results and recommendtaions are summarized from three forums that focused on the pertinent issues of energy trade, energy efficiency and energy diversification. The inaugural forum (Energy Trade) was held in Washington, D.C. in the fall of 2005. The following summer, the second forum (Energy Efficiency) took place in Mexico City. The third forum (Energy Diversification) was hosted in Halifax, Nova Scotia.

  13. Discrimination against Muslim American adolescents.

    Aroian, Karen J

    2012-06-01

    Although there is ample evidence of discrimination toward Muslim Americans in general, there is limited information specific to Muslim American adolescents. The few existing studies specific to this age group suggest that Muslim American adolescents encounter much discrimination from teachers, school administrators, and classmates. This descriptive qualitative study complements the few existing studies on Muslim American adolescents by obtaining in-depth description of the discrimination they encounter. The sample was 14 Muslim American adolescents who participated in one of two gender-specific focus groups about their discrimination experiences. Findings identified school settings as rife with discrimination toward Muslims, portrayed Muslim girls as at risk for harassment by strangers in public places, and illustrated how Muslim youth cope with discrimination. The study findings sensitize school nurses to the nature of the problem and provide direction for intervention.

  16. Gothic roots: Brockden Brown's Wieland, American identity, and American literature

    Directory of Open Access Journals (Sweden)

    Renata R. Mautner Wasserman

    2012-11-01

    Charles Brockden Brown’s Wieland (1798, one of the first novels by an American author set in the newly formed United States, and dealing with American topics, is generally classed as a “Gothic” novel and read as exploring issues of national identity. The Gothic form, popular in English literature, where it gave sensationalistic treatment to matters of gender, class, national identity and religious affiliation, proved adaptable to conditions overseas. Wieland, however, is less sanguine about the success of the nation-building and independence-achieving enterprise than other, later, novels of American national identity.

  17. Immigration reform, American style.

    Science.gov (United States)

    Papademetriou, D G

    1984-01-01

    This article reviews the background of the proposed Immigration and Reform Act (also known as the Simpson-Mazzoli bill), which seeks to overhaul US immigration law for the first time since 1952. This bill is consistent with President Reagan's hard line on border enforcement and mandates stiff penalties for those who transport illegal aliens for commercial advantage or private profit. It further offers Mexico preferential treatment in immigration (40,000 additional visas/year). It includes an amnesty program to offer legal status to qualified illegal residents. The bill directs the President to develop a secure national worker identification system and would create a large-scale temporary foreign agricultural program for perishable commodities. Agricultural workers' families would not be eligible to accompany them unless they also obtain temporary visas. Foreign temporary workers, employable only in cases where local domestic workers are not available, must be provided with wages and working conditions equal to those prevailing among domestic workers. Stiff penalties are stipulated for employers who fail to abide with the terms of the program. In the author's opinion, this bill fails to appreciate the global character of international migration and its complexity. It relects a fundamental ambivalence about a strictly controlled main gate versus a back door approach to immigration as well as the conflicting images of the US as a nation of immigrants versus the historical reality of American nativism and xenophobia. Needed are comprehensive initiatives whose mutually reinforcing components can address the multiple dimensions of the immigration problem within a framework that does not ignore workers who have contributed to the economic well-being of the US, regardless of their legal status.

  18. Immigration and the American century.

    Science.gov (United States)

    Hirschman, Charles

    2005-11-01

    The full impact of immigration on American society is obscured in policy and academic analyses that focus on the short-term problems of immigrant adjustment. With a longer-term perspective, which includes the socioeconomic roles of the children of immigrants, immigration appears as one of the defining characteristics of twentieth-century America. Major waves of immigration create population diversity with new languages and cultures, but over time, while immigrants and their descendants become more "American," the character of American society and culture is transformed. In the early decades of the twentieth century, immigrants and their children were the majority of the workforce in many of the largest industrial cities; in recent decades, the arrival of immigrants and their families has slowed the demographic and economic decline of some American cities. The presence of immigrants probably creates as many jobs for native-born workers as are lost through displacement. Immigrants and their children played an important role in twentieth-century American politics and were influential in the development of American popular culture during the middle decades of the twentieth century. Intermarriage between the descendants of immigrants and old-stock Americans fosters a national identity based on civic participation rather than ancestry.

  19. North American oil demand outlook

    International Nuclear Information System (INIS)

    Stewart, M.B.

    1995-01-01

    An understanding of the relationship of economic growth and potential petroleum product demand is needed to forecast the potential for North American oil demand growth as well as knowledge of world supply and price. The bullish expectations for economic growth in the US and Canada auger well for North American refiners and marketeers. The growth in world economic output forecast, however, means a larger oil demand and an increase in OPEC's pricing power. Such price increases could depress North American oil demand growth.

    Full Text Available The study is intended to know the Disney’s animation films characteristics which are adapted from non American stories that contain Americanization in order to be American popular culture products. This qualitative and library research is carried out within the field of American Studies. Disney’s animated films which are regarded as artifacts in order to identify American society and culture is used as her primary data. She then compares those Disney films with the original stories to discover the changes in making those stories become American popular products. She furthermore uses the sources such as books, magazines, journals, articles, and also internet data for her secondary data. The result of this study shows that most of folk narratives which were used in Disney films were adapted from other countries’ stories. However, Disney intentionally adapts foreign countries’ stories in its animated films by using Disney formula to blow up the sale of its products. Since Disney is one of the most powerful media conglomerates in the world, it works endlessly to set out world entertainment. Disney formula in its animated films which has dominated those adapted films are only intended to obtain as much profit as possible without paying attention to the values in children entertainment.

  3. Geothermal energy for American Samoa

    Energy Technology Data Exchange (ETDEWEB)

    1980-03-01

    The geothermal commercialization potential in American Samoa was investigated. With geothermal energy harnessed in American Samoa, a myriad of possibilities would arise. Existing residential and business consumers would benefit from reduced electricity costs. The tuna canneries, demanding about 76% of the island's process heat requirements, may be able to use process heat from a geothermal source. Potential new industries include health spas, aquaculture, wood products, large domestic and transhipment refrigerated warehouses, electric cars, ocean nodule processing, and a hydrogen economy. There are no territorial statutory laws of American Samoa claiming or reserving any special rights (including mineral rights) to the territorial government, or other interests adverse to a land owner, for subsurface content of real property. Technically, an investigation has revealed that American Samoa does possess a geological environment conducive to geothermal energy development. Further studies and test holes are warranted.

    Television is a beloved American pastime and a frequent American export. As such, American television shapes how the global public views the world. This study examines how the portrayal of blood transfusion and blood donation on American television may influence how domestic and international audiences perceive the field of transfusion medicine. American television programming of the last quarter-century was reviewed to identify programmes featuring topics related to blood banking/transfusion medicine. The included television episodes were identified through various sources. Twenty-seven television episodes airing between 1991 and 2013 were identified as featuring blood bank/transfusion medicine topics. Although some accurate representations of the field were identified, most television programmes portrayed blood banking/transfusion medicine inaccurately. The way in which blood banking/transfusion medicine is portrayed on American television may assist clinicians in understanding their patient's concerns about blood safety and guide blood collection organisations in improving donor recruitment. © 2013 The Author.

    2008-07-01

    This preliminary study explored the cultural socialization processes of 227 African American and European American parents of elementary schoolchildren. The Cultural Value Socialization Scales (K. M. Tyler, A. W. Boykin, C. M. Boelter, & M. L. Dillihunt, 2005) were used to garner parents' reports of their cultural value socialization activities at home. The scales contained written vignettes depicting persons involved in activity that reflected a specific cultural value. Ethnocultural values examined were communalism, verve, movement, and affect, and mainstream cultural values included individualism, competition, bureaucracy, and materialism. Regression analyses reveal that being an African American parent was predictive of competition and materialism scores. Race was not a significant predictor of the remaining cultural value socialization scores. Limitations to the study are discussed. Copyright (c) 2008 APA, all rights reserved.

    Science.gov (United States)

    Windholz, G

    1983-10-01

    Pavlov's development of the conditional reflex theory coincided with the rise of American behaviorism. Substituting an objective physiology for a subjective psychology, Pavlov saw in the rise of American behaviorism a clear confirmation of his method and theory. But in the early 1930s, Lashley attacked Pavlov's theory of specific cerebral localization of function, proposing instead the concept of an internal cerebral organization; Guthrie objected to Pavlov's centralist interpretation of conditioning, proposing instead a peripheralist interpretation; while Hull challenged Pavlov's theory of sleep and hypnosis as the manifestations of inhibition. Pavlov replied with critiques of Lashley's, Guthrie's, and Hull's views, and, convinced that Lashley and Guthrie misunderstood his position, repeated his method's and theory's basic propositions. Yet, Pavlov never gave up the expectation that American behaviorism would accept his conditional reflex theory and saw in Hunter's 1932 statements a support of his assumptions.

    The purpose of this literature review is to promote a better understanding of the construct of dietary acculturation in recent years and how it affects dietary intake of Asian-American population. Four databases were searched simultaneously using the following key terms: Asian-Americans, dietary practices, eating habits, and dietary acculturation. A total of seven articles were relevant and met the inclusion criteria. The findings from these studies of dietary acculturation in Asian Americans are generally in agreement with other dietary acculturation research conducted in non-Asian population samples. Although the studies presented in this literature review represent the recent researches conducted in Asian populations in the US, the research in dietary acculturation remains sparse.

  5. Foundation Networks and American Hegemony

    Directory of Open Access Journals (Sweden)

    Inderjeet Parmar

    2012-02-01

    Full Text Available The major American foundations constructed and sustained the rich texture of cooperative social, intellectual and political relations between key actors and institutions supportive of specific modes of thought that promoted US hegemony. Foundations also fostered and developed the attractive power-knowledge networks that not only radiated intellectual influence but also attracted some of the most creative minds. Finally, liberal internationalist foundations fostered globalism even when the American state was ‘isolationist’, and when US influence abroad unwelcome. Their significance in American hegemony building lay in their sustained, long-term cooperative relationship with the American state through which they helped build national, international and global institutions and networks. The latter process evidences the most significant impact of US foundations – the building of the domestic and international infrastructure for liberal internationalism which has transformed into a kind of “social neoliberalism”. Theoretical conclusions follow from these claims: the sustained and deep cooperation between the state and foundations suggests that we must revise our views of “how power works” in the United States and therefore influences its foreign relations. Therefore, the article shows that elite networks, consisting of state officials and private citizens are powerful means by which foreign policy shifts may be prepared, elite and mass opinion primed and mobilised, new consensus built, ‘old’ forces marginalised, and US hegemony constructed.

  7. American neurophysiology and two nineteenth-century American Physiological Societies.

    Science.gov (United States)

    Lazar, J Wayne

    2017-01-01

    This article contrasts two American Physiological Societies, one founded near the beginning of the nineteenth century in 1837 and the other founded near its end in 1887. The contrast allows a perspective on how much budding neuroscience had developed during the nineteenth century in America. The contrast also emphasizes the complicated structure needed in both medicine and physiology to allow neurophysiology to flourish. The objectives of the American Physiological Society of 1887 were (and are) to promote physiological research and to codify physiology as a discipline. These would be accomplished by making physiology much more inclusive than traditionally accepted by raising research standards, by giving prestige to its members, by providing members a source of professional interchange, by protecting its members from antivivisectionists, and by promoting physiology as fundamental to medicine. The quantity of neuroscientific experiments by its members was striking. The main organizers of the society were Silas Weir Mitchell, John Call Dalton, Henry Pickering Bowditch, and Henry Newell Martin. The objective of the American Physiological Society of 1837 was to disperse knowledge of the "laws of life" and to promote human health and longevity. The primary organizers were William Andrus Alcott and Sylvester Graham with the encouragement of John Benson. Its technique was to use physiological information, not create it as was the case in 1887. Its object was to disseminate the word that healthy eating will improve the quality of life.

    The peopling of the Americas has been the subject of extensive genetic, archaeological and linguistic research; however, central questions remain unresolved. One contentious issue is whether the settlement occurred by means of a single migration or multiple streams of migration from Siberia. The pattern of dispersals within the Americas is also poorly understood. To address these questions at a higher resolution than was previously possible, we assembled data from 52 Native American and 17 Siberian groups genotyped at 364,470 single nucleotide polymorphisms. Here we show that Native Americans descend from at least three streams of Asian gene flow. Most descend entirely from a single ancestral population that we call 'First American'. However, speakers of Eskimo-Aleut languages from the Arctic inherit almost half their ancestry from a second stream of Asian gene flow, and the Na-Dene-speaking Chipewyan from Canada inherit roughly one-tenth of their ancestry from a third stream. We show that the initial peopling followed a southward expansion facilitated by the coast, with sequential population splits and little gene flow after divergence, especially in South America. A major exception is in Chibchan speakers on both sides of the Panama isthmus, who have ancestry from both North and South America.

    Full Text Available A survey for canine tegumentary leishmaniasis (CTL has been carried out between 1986 and 1993 in seven endemic localities for American cutaneous leishmaniasis in the State of Rio de Janeiro. 270 dogs have been examined for their clinical aspects, the development of delayed hypersensitivity (DHS with Immunoleish antigen and with immunofluorescent antibody research of IgG (IF. 28.2% of them had ulcer lesions and 3.3% had scars. The lesions consisted of single (39.5% and mucocutaneous lesions (31.6%, multiple cutaneous (25.0% and mucocutaneous lesions associated with cutaneous ulcers (4.0%. Twelve (15.8% isolates from biopsies were analyzed by zimodeme and schizodeme and identified as L. (V. braziliensis. The overall prevalence of canine infection that was evaluated with the skin test was of 40.5% and with IF it was of 25.5%. Both tests showed a high positive rate with relation to the animals with mucosal lesions, as in the case of human mucocutaneous leishmaniasis. The comparison of the two tests showed the skin test to have a better performance although there was no statistical difference (p>0.05 between them. The proportional sensitivity and specificity was of 84.0% and 74.0%, respectively.

    Limited information is available about Arab Americans' smoking behaviors. The aim of this study was to describe Arab Americans' smoking behaviors and any relationship between tobacco dependence and acculturation. This was a cross-sectional study. Arab American smokers and ex-smokers (N = 96) participated in the study. Nicotine dependence, acculturation, and tobacco use questionnaires were used to measure the major variables. Analyses revealed a significant positive correlation between acculturation and tobacco dependence and between tobacco exposure and tobacco dependence. Arab Americans who behaved most like their ethnic peers and spent more time with Arab Americans were more dependent on nicotine.

    As American lifespans increase, there is greater concern for the quality of those longer lives. The Department of Health and Human Services, through its many component agencies, has inaugurated a major initiative to promote health and fitness among older Americans to improve life quality and to reduce health care costs. The older population is a fertile ground for such an initiative, because studies indicate that the elderly are extremely health-conscious and very willing to adopt habits that will maintain good health. Investigation disclosed six target areas of concentration at which the health promotion initiative could be aimed: fitness-exercise, nutrition, safe and proper use of drugs and alcohol, accident prevention, other preventive services, and smoking cessation. The initiative includes cooperative programs with States; dissemination of printed information; nutritious meals for the elderly; a Food and Drug Administration consumer education program; Centers for Disease Control programs on accident prevention; a special task force to deal with Alzheimer's disease; and, in cooperation with states, a media campaign of health promotion for the elderly. At least three national health and senior citizens organizations are working closely with HHS agencies on the initiative. A separate Department effort involves the encouragement of fast-growing health maintenance organizations to promote health and prevention for their Medicare members and the persuasion of Medicare beneficiaries generally to seek second medical or surgical opinions. State and local government and the private sector, responding to Department initiatives, have also been developing programs for the aging. Their interest and participation ensures that special health promotion and disease prevention efforts directed toward elderly Americans will continue and proliferate.

    Full Text Available Affection is perceived as something natural, pre-existing Culture and, therefore, free form discursive constructions. However, insofar as reality is mediated, if not given existence by language, human relationships are inevitably fashioned by narratives. Romance fictions and in particular heterosexual, interracial love stories have been used in U.S. popular culture as a means of promoting American democratic values of racial harmony at home and abroad. This will be exemplified by analyzing James A. Michener’s 1953 novel Sayonara together with Joshua Logan’s 1957 film adaptation.

The group's findings are based partly on the results of a set of economic models of the natural gas industry that were run for four scenarios representing significantly different conditions: two oil price scenarios (upper and lower), a smaller total US resource base (low US resource case), and increased potential gas demand for electric generation (high US demand case). Several issues, such as the direction of regulatory policy and the size of the gas resource base, were analyzed separately without the use of models

    1994-01-01

    The introduction will set out the principal theme of the book: that the rise of the U.S. space program was due to a concerted effort by science writers, engineers, industrialists, and civic and political leaders to create a popular culture of space exploration based on important elements of American social life (such as frontier mythology, fears about the cold war, and the rise of the consumer culture). Much of the disillusionment with the NASA space program which set in during the third decade of space flight can be traced to a widening gap between popular expectations and the reality of space exploration.

    The peopling of the Americas has been the subject of extensive genetic, archaeological and linguistic research; however, central questions remain unresolved1–5. One contentious issue is whether the settlement occurred via a single6–8 or multiple streams of migration from Siberia9–15. The pattern of dispersals within the Americas is also poorly understood. To address these questions at higher resolution than was previously possible, we assembled data from 52 Native American and 17 Siberian groups genotyped at 364,470 single nucleotide polymorphisms. We show that Native Americans descend from at least three streams of Asian gene flow. Most descend entirely from a single ancestral population that we call “First American”. However, speakers of Eskimo-Aleut languages from the Arctic inherit almost half their ancestry from a second stream of Asian gene flow, and the Na-Dene-speaking Chipewyan from Canada inherit roughly one-tenth of their ancestry from a third stream. We show that the initial peopling followed a southward expansion facilitated by the coast, with sequential population splits and little gene flow after divergence, especially in South America. A major exception is in Chibchan-speakers on both sides of the Panama Isthmus, who have ancestry from both North and South America. PMID:22801491

  11. Influences of culture on Asian Americans' sexuality.

    Okazaki, Sumie

    2002-02-01

    Asian Americans comprise a population group that is characterized by an enormous demographic, historical, and cultural heterogeneity, yet Asian Americans also share many Asian cultural characteristics such as the primacy of the family and the collective's goals over individual wishes, emphasis on propriety and social codes, the appropriation of sexuality only within the context of marriage, and sexual restraint and modesty. Although there are significant gaps in the scientific literature concerning Asian Americans sexuality, the existing data point to notable differences between Asian Americans and other ethnic groups on major aspects of sexual behavior. For example, relative to other U.S. ethnic group cohorts, Asian American adolescents and young adults tend to show more sexually conservative attitudes and behavior and initiate sexual intercourse at a later age. There are indications that as Asian Americans become more acculturated to the mainstream American culture, their attitudes and behavior become more consistent with the White American norm. Consistent with their more sexually conservative tendencies in normative sexual behavior, Asian American women also appear more reluctant to obtain sexual and reproductive care, which in turn places them at a greater risk for delay in treatment for breast and cervical cancer as well as other gynecological problems. Available data suggest that the prevalence rate of sexual abuse in Asian American communities appear lower than those of other groups, although it is not clear to what extent the low rates are due to cultural reluctance to report shameful experiences.

  12. The Relationship between Native American Ancestry, Body Mass Index and Diabetes Risk among Mexican-Americans.

    Hao Hu

    Full Text Available Higher body mass index (BMI is a well-established risk factor for type 2 diabetes, and rates of obesity and type 2 diabetes are substantially higher among Mexican-Americans relative to non-Hispanic European Americans. Mexican-Americans are genetically diverse, with a highly variable distribution of Native American, European, and African ancestries. Here, we evaluate the role of Native American ancestry on BMI and diabetes risk in a well-defined Mexican-American population. Participants were randomly selected among individuals residing in the Houston area who are enrolled in the Mexican-American Cohort study. Using a custom Illumina GoldenGate Panel, we genotyped DNA from 4,662 cohort participants for 87 Ancestry-Informative Markers. On average, the participants were of 50.2% Native American ancestry, 42.7% European ancestry and 7.1% African ancestry. Using multivariate linear regression, we found BMI and Native American ancestry were inversely correlated; individuals with 80% Native American ancestry. Furthermore, we demonstrated an interaction between BMI and Native American ancestry in diabetes risk among women; Native American ancestry was a strong risk factor for diabetes only among overweight and obese women (OR = 1.190 for each 10% increase in Native American ancestry. This study offers new insight into the complex relationship between obesity, genetic ancestry, and their respective effects on diabetes risk. Findings from this study may improve the diabetes risk prediction among Mexican-American individuals thereby facilitating targeted prevention strategies.

    The present study examined the relationships between adherence to Asian and European cultural values and communication styles among 210 Asian American and 136 European American college students. A principal components analysis revealed that, for both Asian Americans and European Americans, the contentious, dramatic, precise, and open styles loaded onto the first component suggesting low context communication, and interpersonal sensitivity and inferring meaning styles loaded onto the second component suggesting high context communication. Higher adherence to emotional self-control and lower adherence to European American values explained Asian Americans' higher use of the indirect communication, while higher emotional self-control explained why Asian Americans use a less open communication style than their European American counterparts. When differences between sex and race were controlled, adherence to humility was inversely related to contentious and dramatic communication styles but directly related to inferring meaning style, adherence to European American values was positively associated with precise communication and inferring meaning styles, and collectivism was positively related to interpersonal sensitivity style. 2008 APA

    The rapid increase in acceptability of various potential exploration and production venture opportunities throughout most of Latin America has created yet another watershed in our ever changing industry. Who would have believed a very short while ago that ventures in Latin America would compete successfully for risk funds against well established opportunities in such areas as the North Sea or Asia Pacific and even with the heady prospects continuing to appear in the CIS? Is this competition real, or is it another industry myth which sets sights too high and where we chase each others pot of gold before reality sets in? Let us try and examine some of the reasons why the current enthusiasms may be justified, particularly so in the case of North American investment.

Polymerase chain reaction (PCR assays of patient lesions were positive for Leishmania, subgenus Viannia. One isolate was obtained by culture (from patient 2 biopsy samples and characterized as Leishmania (Viannia naiffi through an indirect immunofluorescence assay (IFA with species-specific monoclonal antibodies (mAbs and by multilocus enzyme electrophoresis (MLEE. Patients were successfully treated with N-methyl-glucamine. These two cases highlight the potential risks of laboratory and field work and the need to comply with strict biosafety procedures in daily routines. The swab collection method, coupled with PCR detection, has greatly improved ACL laboratory diagnosis.

    2010-11-01

    In the past 10 years, information about South American camelid anatomy, physiology, medicine, and surgery has increased exponentially, including information about the eye. Although trauma-related diseases are the most common eye problems for which camelids are presented to veterinarians, there have recently been many anecdotal reports and published case reports of camelids having ocular malignancies and potentially hereditary ocular abnormalities. The increased number of ocular diseases being reported may be because of increased recognition of camelid diseases or an increase in these diseases as a result of restricted gene pools as a consequence of inbreeding. As the popularity of camelids is steadily increasing, owners are becoming more knowledgeable about their animals, and there is more need for veterinarians who understand their ocular anatomy, physiology, disease susceptibility, and recommended treatments. This article provides the relevant information about the eye. Copyright © 2010 Elsevier Inc. All rights reserved.

    Meso american archaeology works with large amounts of disperse and diverse information, thus the importance of including new methods that optimise the acquisition, conservation, retrieval, and analysis of data to generate knowledge more efficiently and create a better understanding of history. Further, this information --which includes texts, coordinates, raster graphs, and vector graphs-- comes from a considerable geographical area --parts of Mexico, Nicaragua, Honduras and Costa Rica as well as Guatemala, El Salvador and Belize-- is constantly expanding. This information includes elements like shards, buildings, mural paintings, high and low reliefs, topography, maps, and information about the fauna and soil. Grid computing offers a solution to handle all this information: it respects researchers' need for independence while supplying a platform to share, process and compare the data obtained. Additionally, the Grid can enhance space-time analyses with remote visualisation techniques that can, in turn, incorporate geographical information systems and virtual reality. (Author)

    Full Text Available This study focuses on the depiction of homosexuality in American films. It is intended to identify the images of gays depicted in American films as well as the characteristics of American gay movies. It incorporates library research by applying an analytical descriptive approach in analyzing the data. The symbol and reflective theory is used to analyze 18 American movies and 14 gay films from other countries in the early 2000s. It shows that gay films can attract audiences by describing gays as the objects for laughs; gays revealing their sexual identities; sexual scenes of gays; masculine gay men; and violence in gay life. They appear in genres like drama, comedy, romance, detective, western, and horror/mystery with two images of gay people shown in American gay movies; they are the portrait of gays as a minority and the pessimism. However, it also shows that some American gay films picture good gay life, happy gay couples, gay marriage, etc.

    Full Text Available Arab-American (AA populations in the US are exposed to discrimination and acculturative stress-two factors that have been associated with higher suicide risk. However, prior work suggests that socially oriented norms and behaviors, which characterize recent immigrant ethnic groups, may be protective against suicide risk. Here we explored suicide rates and their determinants among AAs in Michigan, the state with the largest proportion of AAs in the US.ICD-9/10 underlying cause of death codes were used to identify suicide deaths from among all deaths in Michigan between 1990 and 2007. Data from the 2000 U.S. Census were collected for population denominators. Age-adjusted suicide rates among AAs and non-ethnic whites were calculated by gender using the direct method of standardization. We also stratified by residence inside or outside of Wayne County (WC, the county with the largest AA population in the state. Suicide rates were 25.10 per 100,000 per year among men and 6.40 per 100,000 per year among women in Michigan from 1990 to 2007. AA men had a 51% lower suicide rate and AA women had a 33% lower rate than non-ethnic white men and women, respectively. The suicide rate among AA men in WC was 29% lower than in all other counties, while the rate among AA women in WC was 20% lower than in all other counties. Among non-ethnic whites, the suicide rate in WC was higher compared to all other counties among both men (12% and women (16%.Suicide rates were higher among non-ethnic white men and women compared to AA men and women in both contexts. Arab ethnicity may protect against suicide in both sexes, but more so among men. Additionally, ethnic density may protect against suicide among Arab-Americans.

    OBJECTIVE—To report the 2001 prevalence and 2002–2005 incidence of type 1 and type 2 diabetes in Hispanic American youth and to describe the demographic, clinical, and behavioral characteristics of these youth. RESEARCH DESIGN AND METHODS—Data from the SEARCH for Diabetes in Youth Study, a population-based multicenter observational study of youth aged 0–19 years with physician-diagnosed diabetes, were used to estimate the prevalence and incidence of type 1 and type 2 diabetes. Information obtained by questionnaire, physical examination, and blood and urine collection was analyzed to describe the characteristics of youth who completed a study visit. RESULTS—Among Hispanic American youth, type 1 diabetes was more prevalent than type 2 diabetes, including in youth aged 10–19 years. There were no significant sex differences in type 1 or type 2 diabetes prevalence. The incidence of type 2 diabetes for female subjects aged 10–14 years was twice that of male subjects (P < 0.005), while among youth aged 15–19 years the incidence of type 2 diabetes exceeded that of type 1 diabetes for female subjects (P < 0.05) but not for male subjects. Poor glycemic control, defined as A1C ≥9.5%, as well as high LDL cholesterol and triglycerides were common among youth aged ≥15 years with either type of diabetes. Forty-four percent of youth with type 1 diabetes were overweight or obese. CONCLUSIONS—Factors such as poor glycemic control, elevated lipids, and a high prevalence of overweight and obesity may put Hispanic youth with type 1 and type 2 diabetes at risk for future diabetes-related complications.

    Mental illness stigma is prevalent among Asian Americans, and it is a key barrier that prevents them from seeking psychological services. Limited studies have experimentally examined how Asian Americans respond to biological and social explanations of mental illness. Understanding how to educate and communicate about mental illness effectively is crucial in increasing service utilization among Asian Americans. To assess how genetic, neurobiological, and social explanations for the onset of depression affects Asian American and European American's mental illness stigma. 231 Asian Americans and 206 European Americans read about an individual with major depression and were randomly assigned to be informed that the cause was either genetic, neurobiological, social, or unknown. Various stigma outcomes, including social distance, fear, and depression duration were assessed. Consistent with prior research, Asian Americans had higher baseline levels of stigma compared to European Americans. Greater social essentialist beliefs predicted positive stigma outcomes for Asian Americans, such as a greater willingness to be near, help, and hire someone with depression, but genetic essentialist beliefs predicted negative stigma outcomes, such as fear. In addition, a social explanation for the etiology of depression led to lower stigma outcomes for Asian Americans; it decreased their fear of someone with depression and increased the perception that depression is treatable. For European Americans, both genetic and social essentialist beliefs predicted a greater perception of depression treatability. Although genetics do play a role in the development of depression, emphasizing a social explanation for the origin of depression may help reduce stigma for Asian Americans.

Recent reports from the WHO and the World Bank highlight the importance of chronic diseases such as hypertension as an obstacle to the achievement of good health status. It must be added that for most low and middle-income countries, deficient strategies of primary healthcare are the major obstacles for blood pressure control. Furthermore, the epidemiology of hypertension and related diseases, healthcare resources and priorities, the socioeconomic status of the population vary considerably in different countries and in different regions of individual countries. Considering the low rates of blood pressure control achieved in Latin America and the benefits that can be expected from an improved control, it was decided to invite specialists from different Latin American countries to analyze the regional situation and to provide a consensus document on detection, evaluation and treatment of hypertension that may prove to be cost-utility adequate. The recommendations here included are the result of preparatory documents by invited experts and a subsequent very active debate by different discussion panels, held during a 2-day sessions in Asuncion, Paraguay, in May 2008. Finally, in order to improve clinical practice, the publication of the guidelines should be followed by implementation of effective interventions capable of overcoming barriers (cognitive, behavioral and affective) preventing attitude changes in both physicians and patients.

  14. The relationship between momentary emotions and well-being across European Americans, Hispanic Americans, and Asian Americans.

    Choi, Eunsoo; Chentsova-Dutton, Yulia E

    2017-09-01

    Cultural differences in the emphasis on positive and negative emotions suggest that the impact of these emotions on well-being may differ across cultural contexts. The present study utilised a momentary sampling method to capture average momentary emotional experiences. We found that for participants from cultural contexts that foster positive emotions (European Americans and Hispanic Americans), average momentary positive emotions predicted well-being better than average momentary negative emotions. In contrast, average momentary negative emotions were more strongly associated with well-being measures for Asian Americans, the group from a cultural context that emphasises monitoring of negative emotions. Furthermore, we found that acculturation to American culture moderated the association between average momentary positive emotions and well-being for Asian Americans. These findings suggest the importance of culture in studying the impact of daily emotional experiences on well-being.

    The true prevalence of smoking among characters portrayed in the movies is unknown. This study examines this prevalence objectively. The top 10 movies on the weekly box office charts were reviewed. Whether or not the top five characters in these movies smoked, was documented. It was determined prior to the start of the study that 300 male characters and 300 female characters were needed to detect any significant difference. A total of 447 movies, composed of 193 movies rated restricted (R) [children movies rated PG13 for parental guidance suggested for children movies rated PG for parental guidance suggested, were examined until the sample size was reached. Smoking prevalence is the same in contemporary American movies and in the general US population (23.3% vs 24.8%, respectively). However, there was more smoking in these movies among men than among women (25.5% vs 20.5%, respectively; p movies (46.2% vs 18.2%, respectively; p movies (37.3%, 16.2%, and 8.1%, respectively; p movies, and in both subcategories of R-rated studio movies and R-rated independent movies, smoking prevalence is higher than in the US population (37.3%, 30.5%, and 50.6% vs 24.8%, respectively; p movies, R-rated studio movies, and R-rated independent movies. In R-rated movies, antagonists smoke more than protagonists (43.9% vs 35.8%, respectively; p movies, antagonists smoke more than protagonists (42.6% vs 26.6%, respectively; p movies, whites smoke more than nonwhites (51.8% vs 40.5%, respectively; p movies than in R-rated studio movies (50.6% vs 30.5%, respectively; p movies than in R-rated studio movies in subcategories of men (32.0% vs 49.8%, respectively; p movies, and R-rated movies. Smoking prevalence is higher than in the general US population in R-rated movies, and in both its subcategories of R-rated studio movies and R-rated independent movies. There is more smoking in R-rated independent movies than in R-rated studio movies. Smoking in contemporary American cinema is associated

  11. Passage of American shad: paradigms and realities

    Science.gov (United States)

    Haro, Alex; Castro-Santos, Theodore

    2012-01-01

    Despite more than 250 years of development, the passage of American shad Alosa sapidissima at dams and other barriers frequently remains problematic. Few improvements in design based on knowledge of the swimming, schooling, and migratory behaviors of American shad have been incorporated into passage structures. Large-scale technical fishways designed for the passage of adult salmonids on the Columbia River have been presumed to have good performance for American shad but have never been rigorously evaluated for this species. Similar but smaller fishway designs on the East Coast frequently have poor performance. Provision of effective downstream passage for both juvenile and postspawning adult American shad has been given little consideration in most passage projects. Ways to attract and guide American shad to both fishway entrances and downstream bypasses remain marginally understood. The historical development of passage structures for American shad has resulted in assumptions and paradigms about American shad behavior and passage that are frequently unsubstantiated by supporting data or appropriate experimentation. We propose that many of these assumptions and paradigms are either unfounded or invalid and that significant improvements to American shad upstream and downstream passage can be made via a sequential program of behavioral experimentation, application of experimental results to the physical and hydraulic design of new structures, and controlled tests of large-scale prototype structures in the laboratory and field.

  12. Drug testing in American schools

    Directory of Open Access Journals (Sweden)

    C.J. Russo

    2003-08-01

    Full Text Available As the use of illegal drugs has reached epidemic proportions in schools, educational leaders in the United States have turned to drug testing in attempting to maintain learner discipline. To this end, the United States Supreme Court has addressed the issue twice in the past eight years. In 1995, the Court permitted drug testing in Acton v. Vernonia School District 47J. More recently, in Board of Education of Independent School District No. 92 of Pottawatomie v. Earls (2002, the Court upheld suspicionless drug testing of learners who wished to participate in extracurricular activities. Even though drug testing has yet to emerge as an issue in South Africa, Earls is significant for educational leaders and policy makers in South Africa since it involves concerns under the National Policy on Privacy. More specifically, under Items 20 and 21 of the South African National Policy on the Management of Drug Abuse (SA, 1996b searches and drug testing should only be used where there is reasonable suspicion, the same standard applied by American courts. However, unlike the United States, the South African policy prohibits random searches and/or drug testing. Thus, due to constitutional and educational issues that drug testing raises, a timely discussion of this matter should be of interest to educational leaders and policy makers in South Africa.

  13. Arsenic Content in American Wine.

    Wilson, Denise

    2015-10-01

    Recent studies that have investigated arsenic content in juice, rice, milk, broth (beef and chicken), and other foods have stimulated an interest in understanding how prevalent arsenic contamination is in the U.S. food and beverage supply. The study described here focused on quantifying arsenic levels in wine. A total of 65 representative wines from the top four wine-producing states in the U.S. were analyzed for arsenic content. All samples contained arsenic levels that exceeded the U.S. Environmental Protection Agency (U.S. EPA) exposure limit for drinking water of 10 parts per billion (ppb) and all samples contained inorganic arsenic. The average arsenic detected among all samples studied was 23.3 ppb. Lead, a common co-contaminant to arsenic, was detected in 58% of samples tested, but only 5% exceeded the U.S. EPA exposure limit for drinking water of 15 ppb. Arsenic levels in American wines exceeded those found in other studies involving water, bottled water, apple juice, apple juice blend, milk, rice syrup, and other beverages. When taken in the context of consumption patterns in the U.S., the pervasive presence of arsenic in wine can pose a potential health risk to regular adult wine drinkers.

    Myrna Serapião dos Santos

    2011-12-01

    Full Text Available PURPOSE: To establish current definition, classification and staging, and to develop diagnosis and treatment recommendations for ocular allergy, by using Delphi approach. METHODS: Ten Latin American experts on ocular allergy participated in a 4-round Delphi panel approach. Four surveys were constructed and answered by panelists. A two-thirds majority was defined as consensus. Definition, classification, staging and diagnosis and treatment recommendations were the main outcomes. RESULTS: "Ocular allergy" was proposed as the general term to describe ocular allergic diseases. Consensus regarding classification was not reached. Signs and symptoms were considered extremely important for the diagnosis. It was consensus that a staging system should be proposed based on the disease severity. Environmental control, avoidance of allergens and the use of artificial tears were recommended as first line treatment. The secondary treatment should include topical anti-histamines, mast cell stabilizers and multi actions drugs. Topical non-steroidal anti-inflammatory and vasoconstrictors were not recommended. Topical corticosteroids were recommended as third line of treatment for the most severe keratoconjunctivitis. Consensus was not reached regarding the use of systemic corticosteroids or immunosuppressant. Surgical approach and unconventional treatments were not recommended as routine. CONCLUSION: The task of creating guidelines for ocular allergies showed to be very complex. Many controversial topics remain unsolved. A larger consensus including experts from different groups around the world may be needed to further improve the current recommendations for several aspects of ocular allergy.

  15. North American sturgeon otolith morphology

    Chalupnicki, Marc A.; Dittman, Dawn E.

    2016-01-01

    Accurate expedient species identification of deceased sturgeon (Acipenseridae) when external physical characteristic analysis is inconclusive has become a high priority due to the endangered or threatened status of sturgeon species around the world. Examination of otoliths has provided useful information to aid in population management, age and size-class analysis, understanding predator–prey interactions, and archeological research in other fish species. The relationship between otolith characteristics and sturgeon species has remained unknown. Therefore, we analyzed the shape of otoliths from the eight species of sturgeon found in North America to test the utility of otolith characteristic morphology in species identification. There were distinct differences in the size and shape of the otoliths between species of sturgeon with little shape variation among individuals of the same species. The relationship between otolith length axes was linear, and most of the variability was explained by a Log (axis + 1) transformation of the x and y axes (r2 = 0.8983) using the equation y = 0.73x + 0.0612. Images of otoliths from all eight North American species are presented to assist in the identification process.

  16. Defining Tiger Parenting in Chinese Americans

    Science.gov (United States)

    Kim, Su Yeong

    2016-01-01

    “Tiger” parenting, as described by Amy Chua [2011], has instigated scholarly discourse on this phenomenon and its possible effects on families. Our eight-year longitudinal study, published in the Asian American Journal of Psychology [Kim, Wang, Orozco-Lapray, Shen, & Murtuza, 2013b], demonstrates that tiger parenting is not a common parenting profile in a sample of 444 Chinese American families. Tiger parenting also does not relate to superior academic performance in children. In fact, the best developmental outcomes were found among children of supportive parents. We examine the complexities around defining tiger parenting by reviewing classical literature on parenting styles and scholarship on Asian American parenting, along with Amy Chua’s own description of her parenting method, to develop, define, and categorize variability in parenting in a sample of Chinese American families. We also provide evidence that supportive parenting is important for the optimal development of Chinese American adolescents. PMID:27182075

  17. THE GODFATHER AND THE AMERICAN DREAM

    Directory of Open Access Journals (Sweden)

    Goksu Gigi Akkan

    2017-01-01

    Full Text Available This paper tries to demonstrate how The Godfather by Francis Ford Coppola challenges the myth of the American Dream. The thesis of the paper is that The Godfather is not a film seeking to re-establish American norms and ideals, but that it tries to break down and shed light on the corrupt side of the modern American society through the myth of “the American Dream”. The structure of the paper is so that first, what other academics and critiques have to say about Coppola’s attempt to criticize the American society and ideals will be visited, as this will give the reader a clearer understanding of the film’s meaning and message. Then, analyses of how certain characters are built and how their presence and attributes contribute to the film’s meaning will be conducted, topped off with the usage of props.

    Full Text Available The paper interrogates cultural specifics of contemporary African American poetry and exhibits translation problems when translating this poetic work. African American writers have always included much of their cultural heritage in their writing and this is immediately noticed by a translator. The cultural elements, such as African American cuisine, attire and style in general, as well as spiritual and religious practices, often play a significant role for African American poets who are proclaiming their identity. Moreover, the paper presents the translation problems that emerge when attempting to transfer such a specific, even exotic, source culture into a target culture, like Slovene. The goal is to show to what extent contemporary African American poetry can successfully be translated into the Slovene language and to highlight the parts that inevitably remain lost in the translation process.

    "Tiger" parenting, as described by Amy Chua [2011], has instigated scholarly discourse on this phenomenon and its possible effects on families. Our eight-year longitudinal study, published in the Asian American Journal of Psychology [Kim, Wang, Orozco-Lapray, Shen, & Murtuza, 2013b], demonstrates that tiger parenting is not a common parenting profile in a sample of 444 Chinese American families. Tiger parenting also does not relate to superior academic performance in children. In fact, the best developmental outcomes were found among children of supportive parents. We examine the complexities around defining tiger parenting by reviewing classical literature on parenting styles and scholarship on Asian American parenting, along with Amy Chua's own description of her parenting method, to develop, define, and categorize variability in parenting in a sample of Chinese American families. We also provide evidence that supportive parenting is important for the optimal development of Chinese American adolescents.

    Full Text Available Marsupials, one of the three main groups of mammals, are only found in Australia and in the American continent. Studies performed in Australian marsupials have demonstrated the great potential provided by the group for the understanding of basic genetic mechanisms and chromosome evolution in mammals. Genetic studies in American marsupials are relatively scarce and cytogenetic data of most species are restricted to karyotype descriptions, usually without banding patterns. Nevertheless, the first marsupial genome sequenced was that of Monodelphis domestica, a South American species. The knowledge about mammalian genome evolution and function that resulted from studies on M. domestica is in sharp contrast with the lack of genetic data on most American marsupial species. Here, we present an overview of the chromosome studies performed in marsupials with emphasis on the South American species.

    This study examined African-Americans' use of comprehensive mental health services. 248 long-term users of self-help agencies (SHAs) were interviewed about their use of 37 different mental health services from various providers in a six-month period. Multiple regression analysis showed that the homeless and African-Americans were the high users in our sample. A subsequent MANOVA procedure suggested that this may be the result of African-Americans' increased use of SHAs. While African-Americans are low service users in traditional studies focusing on a narrow list of services and providers, this research argues for including SHAs in future studies of African-American service use.

    Violence against African American women, specifically intimate partner abuse, has a significant impact on their health and well being. Intimate partner femicide and near fatal intimate partner femicide are the major causes of premature death and disabling injuries for African American women. Yet, despite this, there is a paucity of research and interventions specific and culturally relevant for these women. This article focuses on issues relevant to intimate partner violence and abuse against African American women by examining existing empirical studies of prevalence and health outcomes of intimate partner violence against women in general, plus what limited research there is about African American women, specifically. It includes a discussion of specific recommendations for research, practice, education, and policy to reduce and prevent intimate partner violence against African American women.

    The 1980 US census counted 3.5 million Asian Americans, up from 1.4 million in 1970. Asian Americans made up just 1.5% of the total US population of 226.5 million as of April 1, 1980, but this was the 3rd largest racial or ethnic minority after blacks and Hispanics. Asians increased far more during the 1970s (141%) than blacks (17%) or Hispanics (39%). This Bulletin examines the characteristics of Asian Americans, how their numbers have grown, where they live, how different groups vary in age structure, childbearing, health, and longevity. It reports on the kinds of households Asian Americans form and how they fare with regard to education, occupation, and income. Asian Americans are now often perceived as the model minority. As a whole, they are better educated, occupy higher rungs on the occupational ladder, and earn more than the general US population and even white Americans. This Bulletin presents the 1st comprehensive look at many important facts about Asian Americans and how the groups differ. Special tabulations of data collected in the 1980 census are provided. The 1980 census data are the latest available to give a true picture at the national level of Asian Americans and the various groups among them. The Bulletin examines the current numbers of Asian Americans and how this population is defined. The major Asian American groups are Chinese (21%), Filipinos (20%), Japanese (15%), Vietnamese (21%), Koreans (11%), and Asian Indians (10%). Except for the latest-arrived Vietnamese, the fertility of the 6 groups is lower than the white average. The following areas are also discussed: mortality and health; families and households; education; Asian youth; employment; income and poverty; and future prospects.

  5. Force of infection and evolution of lesions of canine tegumentary leishmaniasis in Northwestern Argentina

    2001-07-01

    Full Text Available A clinical-serological follow-up was carried out in a canine population in endemic foci of Leishmania braziliensis spread in northwestern Argentina. Each dog was studied in at least two visits, 309±15 days (X±SE apart. Some initially healthy dogs (n=52 developed seroconversion or lesions. The clinical evolution of the disease in dogs resembles in many aspects the human disease. Similarities include the long duration of most ulcers with occasional healing or appearance of new ones and the late appearance of erosive snout lesions in some animals. Yearly incidence rates of 22.7% for seroconversion and of 13.5% for disease were calculated as indicators of the force of infection by this parasite upon the canine population.

    2007-01-19

    Seventy-four dogs from the State of Rio de Janeiro with ulcerated cutaneous lesions were submitted to clinical, dermatological, parasitological, mycological, histopathological and cytopathological exams, a leishmanin skin test, an indirect immunofluorescence (IIF) test for leishmaniosis, and nonspecific laboratory tests such as blood count and serum biochemistry. Sporothrix schenckii was isolated from 41 dogs and Leishmania (Viannia) braziliensis was isolated from 33 animals. Most dogs with sporotrichosis were from the municipality of Rio de Janeiro (53.7%) and presented ulcerated cutaneous lesions on the head (68.3%). Laboratory alterations in these animals included anemia (58.5%), hypoalbuminemia (83%) and hyperglobulinemia (75.6%). Histopathology revealed the predominance of a chronic granulomatous inflammatory infiltrate (70.7%), and yeast-like structures were detected in 17% of the histopathological exams and in 32% of the cytological exams. Three of 41 dogs with sporotrichosis were seropositive by IIF for leishmaniosis and 2 of 20 animals tested within this group had a positive leishmanin skin test. Similarly, most of the 33 dogs with leishmaniosis were from the municipality of Rio de Janeiro (69.7%) and had ulcerated cutaneous lesions on the head (84.8%). Laboratory alterations in these animals included anemia (66.7%), hypoalbuminemia (100%) and hyperglobulinemia (91%). Histopathology showed the predominance of a chronic granulomatous inflammatory infiltrate (63.6%) and amastigote forms were detected in 30.3% of the histopathological exams and in 31.8% of the 22 cytological exams performed. About 72.7% of the dogs were seropositive by IIF and five of seven animals had a positive skin test. Due to the clinical similarities, histopathological and nonspecific laboratory results similarities, the serological and skin tests for leishmaniosis positive in dogs with sporotrichosis, and the overlapping endemic areas in Rio de Janeiro, the differential diagnosis between the two diseases requires the demonstration of their respective etiological agents.

  7. Reactivation of cutaneous and mucocutaneous tegumentary leishmaniasis in rheumatoid arthritis patients: an emerging problem?

    Directory of Open Access Journals (Sweden)

    Regina Maia de Souza

    Full Text Available ABSTRACT Rheumatoid arthritis (RA is a chronic condition that is frequent in patients living in tropical areas exposed to leishmaniasis. RA therapy involves immunosuppressant drugs such as methotrexate (MTX, monoclonal antibodies (mAbs and prednisone. We report an unusual presentation of cutaneous (CL or mucocutaneous leishmaniasis (ML in RA patients from an endemic area of leishmaniasis. A 51-year-old woman noted a cutaneous ulcer on her left ankle during MTX and prednisone RA therapy. Initially diagnosed as a venous stasis ulcer, the aspirate of the injury revealed the presence of Leishmania DNA. A 73-year-old woman presenting non-ulcerated, infiltrated and painful erythematous nodules inside her nostrils while receiving MTX, anti-TNF mAb, and prednisone for RA, had also the aspirate of injuries showing the presence of Leishmania DNA. Both patients healed after the therapy with liposomal amphotericin. The RA therapy has changed to low-dose prednisone, without further reactivation episodes. Both cases suggest that CL or ML can reactivate after administration of an immunosuppressant for RA treatment. Therefore, immunosuppressive treatments for RA should be carefully prescribed in patients from endemic areas or with a history of CL and ML.

    Population-wide reductions in cardiovascular disease incidence and mortality have not been shared equally by African Americans. The burden of cardiovascular disease in the African American community remains high and is a primary cause of disparities in life expectancy between African Americans and whites. The objectives of the present scientific statement are to describe cardiovascular health in African Americans and to highlight unique considerations for disease prevention and management. The primary sources of information were identified with PubMed/Medline and online sources from the Centers for Disease Control and Prevention. The higher prevalence of traditional cardiovascular risk factors (eg, hypertension, diabetes mellitus, obesity, and atherosclerotic cardiovascular risk) underlies the relatively earlier age of onset of cardiovascular diseases among African Americans. Hypertension in particular is highly prevalent among African Americans and contributes directly to the notable disparities in stroke, heart failure, and peripheral artery disease among African Americans. Despite the availability of effective pharmacotherapies and indications for some tailored pharmacotherapies for African Americans (eg, heart failure medications), disease management is less effective among African Americans, yielding higher mortality. Explanations for these persistent disparities in cardiovascular disease are multifactorial and span from the individual level to the social environment. The strategies needed to promote equity in the cardiovascular health of African Americans require input from a broad set of stakeholders, including clinicians and researchers from across multiple disciplines. © 2017 American Heart Association, Inc.

    1990-01-01

    Every year, the president of the United States offers his State of the Union address. Here, from one of the most respected managers in America, is a report on the State of American Management. The state of management, says Walter B. Wriston, is good. Despite the predictions of America's decline, our economy continues to prosper. That is because of this fundamental truth: the United States is the only country in the world that renews itself daily. This is the Age of Pluralism, and U.S. business is based on pluralism. The spirit of the entrepreneur has entered the mainstream of U.S. management, transforming bureaucracy and emphasizing leadership. Today's top executives need to be more like politicians than the number-crunchers of yesterday. At the same time, information is flowing more freely, so corporations are eliminating layers of managers who were really just transmission lines. And top managers are learning to listen to the people who are closest to the work. Everyone today is a knowledge worker. The accelerating pace of knowledge has put a greater premium than ever on talent. Globalization is a big part of this new world. From the manager's viewpoint, globalization means that "you're in a marketplace where you're suddenly waking up with a guy...from a country you're not too sure where it is, who's eating your lunch in your hometown." To understand global competition, managers in large and small companies need broad vision. Finally, to deal with change, U.S. managers must confront some issues at home. For instance, our accounting systems are obsolete, both in companies and in our national accounts.(ABSTRACT TRUNCATED AT 250 WORDS)

    1999-01-01

    The wide ranging changes that will drive the evolution of the North American electricity industry in the future are discussed. Deregulation and the advent of competition in both the United States and Canada are the principal forces that will change the shape of the electricity market, bringing new players and new forms of doing business into the marketplace. A review of the current state of the business shows that especially in the United States where deregulation began earlier than in Canada, independent generators already constitute a multi-billion dollar industry. Non-utility generation capacity is about seven per cent of total U.S. capacity and accounts for about 10 per cent of total U. S. electricity supply, including imports. Examples from other industries clearly show that restructuring and the breakup of vertically integrated industries could be accomplished much faster than anticipated, that a decrease in prices followed rapidly as products became more like commodities, and that decreasing prices fostered product differentiation and competition. Major legislation affecting the electric power industry in the U.S. and Canada (U.S. National Energy Policy Act 1992, Alberta Electric Utilities Act 1995, Ontario Energy Competition Act 1998) decreeing open access transmission, unbundling of generation, transmission and ancillary services, and promoting competition, and the impacts of these legislative actions are also reviewed. The most visible impact is the explosion that can be seen in power marketing and energy trading on a scale unimaginable only a few short years ago, where the total volume of trade may be worth multiples of the value of the underlying commodity. At the same time, there is concern about the reliability of the system, and thus making it imperative to find new ways to manage reliability. Various suggestions are made as to how increased reliability of supply could be achieved by better management, new standards and better enforcement of

    2011-12-01

    Full Text Available Dead Stars: American and Philippine Literary Perspectives on the American Colonization of the Philippines examines the American colonization of the Philippines from three distinct but related literary perspectives. The first is the reaction of anti-imperialist American writers Mark Twain, W. E. B. Du Bois, and William James to America’s first foray into the role of colonizer and how their varied essays, letters, and speeches provide an incisive delineation of fundamental conflicts in American identity at the turn of the twentieth century. The book then analyzes how these same conflicts surface in the colonial regime’s use of American literature as a tool to inculcate American values in the colonial educational system. Finally, Dead Stars considers the way three early and important Filipino writers—Paz Marquez Benitez, Maximo Kalaw, and Juan C. Laya—interpret and represent these same tensions in their fiction.

    Full Text Available A nation could be a great one as long as it has a great dream. The best example for this is America. Through its long history, it manages to realize a dream to be a superpower. It can be said that “American Dream” is one of the most significant features for the growth of a “constantly eyeing for winner” culture. American Studies experts call it as a “hegemonic culture” in which American norms, values and cultural practices are considered superior against the world culture. Globalizing the culture has been the most effective engine to spread American cultural values and to shape the global civilizations. Using American Studies perspective, this paper attempts to review the extent to which the “American Dream” has successfully established Americanization, as well as how the hegemonic culture has influenced the lives of peoples across the world in the form of popular culture.

    Higher body mass index (BMI) is a well-established risk factor for type 2 diabetes, and rates of obesity and type 2 diabetes are substantially higher among Mexican-Americans relative to non-Hispanic European Americans. Mexican-Americans are genetically diverse, with a highly variable distribution of Native American, European, and African ancestries. Here, we evaluate the role of Native American ancestry on BMI and diabetes risk in a well-defined Mexican-American population. Participants were randomly selected among individuals residing in the Houston area who are enrolled in the Mexican-American Cohort study. Using a custom Illumina GoldenGate Panel, we genotyped DNA from 4,662 cohort participants for 87 Ancestry-Informative Markers. On average, the participants were of 50.2% Native American ancestry, 42.7% European ancestry and 7.1% African ancestry. Using multivariate linear regression, we found BMI and Native American ancestry were inversely correlated; individuals with ancestry were 2.5 times more likely to be severely obese compared to those with >80% Native American ancestry. Furthermore, we demonstrated an interaction between BMI and Native American ancestry in diabetes risk among women; Native American ancestry was a strong risk factor for diabetes only among overweight and obese women (OR = 1.190 for each 10% increase in Native American ancestry). This study offers new insight into the complex relationship between obesity, genetic ancestry, and their respective effects on diabetes risk. Findings from this study may improve the diabetes risk prediction among Mexican-American individuals thereby facilitating targeted prevention strategies.

    The quality of care received by Arab American patients with type 2 diabetes residing in a city with a large migrant Arab population has not been examined. Arab American adults with a self-reported diagnosis of diabetes were identified in a rigorous cross-sectional, population-based epidemiologic study conducted in Dearborn, MI. Quality of diabetes care was determined by assessing adherence to the American Diabetes Association (ADA) clinical practice recommendations. The Third National Health and Nutrition Examination Survey (NHANES) and the Behavioral Risk Factor Surveillance System (BRFSS) provided data for a national comparison. Among the 53 participants, mean age was 59+/-12 years and the mean duration of diabetes was 11.3+/-13.3 years. The ADA goal for an A1c of Arab American subjects studied were treated less aggressively with pharmacologic agents than recommended by the ADA. 26% of the Arab Americans had an A1c>9.5% as compared to 18% of the national population. Arab Americans generally had worse blood pressure control but better lipid control compared to the national sample. This is the first report of the quality of diabetes care in an Arab American population, and demonstrates sub-optimal quality of care according to the ADA clinical practice recommendations.

    2013-05-01

    In this article, the American Cancer Society estimates the number of new cancer cases and deaths for African Americans and compiles the most recent data on cancer incidence, mortality, survival, and screening prevalence based upon incidence data from the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries and mortality data from the National Center for Health Statistics. It is estimated that 176,620 new cases of cancer and 64,880 deaths will occur among African Americans in 2013. From 2000 to 2009, the overall cancer death rate among males declined faster among African Americans than whites (2.4% vs 1.7% per year), but among females, the rate of decline was similar (1.5% vs 1.4% per year, respectively). The decrease in cancer death rates among African American males was the largest of any racial or ethnic group. The reduction in overall cancer death rates since 1990 in men and 1991 in women translates to the avoidance of nearly 200,000 deaths from cancer among African Americans. Five-year relative survival is lower for African Americans than whites for most cancers at each stage of diagnosis. The extent to which these disparities reflect unequal access to health care versus other factors remains an active area of research. Overall, progress in reducing cancer death rates has been made, although more can and should be done to accelerate this progress through ensuring equitable access to cancer prevention, early detection, and state-of-the-art treatments.

    2013-06-01

    The current review paper summarizes the literature on parental emotion socialization in ethnically diverse families in the United States. Models of emotion socialization have been primarily developed using samples of European American parents and children. As such, current categorizations of "adaptive" and "maladaptive" emotion socialization practices may not be applicable to individuals from different ethnic backgrounds. The review examines current models of emotion socialization, with particular attention paid to the demographic breakdown of the studies used to develop these models. Additionally, the review highlights studies examining emotion socialization practices in African American, Asian American, and Latin American families. The review is synthesized with summarizing themes of similarities and differences across ethnic groups, and implications for culturally sensitive research and practice are discussed.

    Latin American medical orthopedic sub specialties have evolved a lot during the past decade. Foot and ankle surgery for instance, has gained high level of proficiency and competence throughout the international scientific communities. This may be due to the availability of new technology in osteosyntheses, orthopedic devices and surgical instruments used to optimize results, regardless of the low economic resources Latin American countries possess. Also, foot and ankle surgery training is being promoted by several International Medical associations that pursuit scientific knowledge and strengthen the practice. Day to day, more Latin American universities offer Fellowships for on-going training.

    Full Text Available Although Arab-American literature has been in existence in the U.S. for over a century, it has only recently begun to be recognized as part of the ethnic landscape of literary America. However, the last two decades have seen a dramatic increase in publication by Arab-American writers. This literary burgeoning reflects in part the shifting historical, social, and political contexts that have pushed Arab-Americans to the foreground, creating both new spaces for their voices and new urgencies of expression, as well as the flourishing creativity of these writers.

    Smith, Zachary L; Eggener, Scott E; Murphy, Adam B

    2017-08-14

    The purpose of this review is to examine prostate cancer racial disparities specific to the African-American population. African-American men are more likely to be diagnosed with prostate cancer, present at an earlier age; are more likely to have locally advanced or metastatic disease at diagnosis; and have suboptimal outcomes to standard treatments. Prostate cancer treatment requires a nuanced approach, particularly when applying screening, counseling, and management of African-American men. Oncological as well as functional outcomes may differ and are potentially due to a combination of genetic, molecular, behavioral, and socioeconomic factors.

    1980-09-01

    This article examines the applicability of the theories of colonialism and dependency to the present underdeveloped situation of American Indians. In the first section, the theoretical and empirical literature is reviewed. The second section applies the general theory to various US minorities, including American Indians. After discussing the shortcomings of this theoretical framework, the article demonstrates how deficiencies found in the colonial analysis of Indian underdevelopment can be corrected by using the supporting theoretical construct of dependency. Among other things, it suggests that dependency analysis of Native Americans, on the basis of previous research, appears, to offer a potentially unified and coherent explanation for the Indian's continued underdevelopment.

  3. Differences in the tumor microenvironment between African-American and European-American breast cancer patients.

    Full Text Available African-American breast cancer patients experience higher mortality rates than European-American patients despite having a lower incidence of the disease. We tested the hypothesis that intrinsic differences in the tumor biology may contribute to this cancer health disparity.Using laser capture microdissection, we examined genome-wide mRNA expression specific to tumor epithelium and tumor stroma in 18 African-American and 17 European-American patients. Numerous genes were differentially expressed between these two patient groups and a two-gene signature in the tumor epithelium distinguished between them. To identify the biological processes in tumors that are different by race/ethnicity, Gene Ontology and disease association analyses were performed. Several biological processes were identified which may contribute to enhanced disease aggressiveness in African-American patients, including angiogenesis and chemotaxis. African-American tumors also contained a prominent interferon signature. The role of angiogenesis in the tumor biology of African-Americans was further investigated by examining the extent of vascularization and macrophage infiltration in an expanded set of 248 breast tumors. Immunohistochemistry revealed that microvessel density and macrophage infiltration is higher in tumors of African-Americans than in tumors of European-Americans. Lastly, using an in silico approach, we explored the potential of tailored treatment options for African-American patients based on their gene expression profile. This exploratory approach generated lists of therapeutics that may have specific antagonistic activity against tumors of African-American patients, e.g., sirolimus, resveratrol, and chlorpromazine in estrogen receptor-negative tumors.The gene expression profiles of breast tumors indicate that differences in tumor biology may exist between African-American and European-American patients beyond the knowledge of current markers.

  1. John Dewey and progressivism in American education

    Directory of Open Access Journals (Sweden)

    Radu, L.

    2011-01-01

    Full Text Available This paper is focused on Progressivism, as a reaction against theAmerican traditional school in order to accomplish the purpose ofconnecting education to the realities imposed by the rapid changes of the American society. Progressivism was developed by John Dewey’s pedagogic theory, being based on Pragmatism, a specific American philosophy, and on instrumentalism, one of its variants to which John Dewey conferred its climax. Experience represented the core concept of his philosophy. After revising this philosophical current, the paper will deal with John Dewey’s pedagogic theory insisting on the method of solving problems as a general method of instruction. The importance of the two schools (Dalton Plan and Winnetka, both based on the progressive theory, will be highlighted. Progressivism opened a new era in American Education based on an active education, which took into account the students’ individualities, stimulatingteachers’ creativity and focusing on a practice based education.

    Latin America embodies countries of special interest for ecological studies, given that areas with great value for biodiversity are located within their territories. This highlights the importance of an evaluation of ecological research in the Latin America region. We assessed the scientific participation of Latin American researchers in ecological journals, patterns of international collaboration, and defined the main characteristics of the articles. Although Latin American publications have increased in fourteen years, they accounted up to 9% of publications in Ecology. Brazil leaded the scientific production in Latin America, followed by Argentina and Mexico. In general, Latin American articles represented a low percentage of most journals total publication, with particularly low expression in high impact-factor journals. A half of the Latin American publications had international collaboration. Articles with more than five authors and with international collaboration were the most cited. Descriptive studies, mainly based in old theories, are still majority, suggesting that Ecology is in a developing stage in Latin America.

  10. Sally Mann's American vision of the land

    Directory of Open Access Journals (Sweden)

    Ayelet Carmi

    2017-12-01

    Full Text Available The American photographer Sally Mann is one of the best-known female artists of our time. She is known primarily for her family photographs Immediate Family from 1992, which provoked intense controversies in the American media and art world, around child pornography and motherhood. While these photographs occupy a central place in the artistic discourse about Mann, her series of landscape photographs remain relatively unexamined. This study examines Mann's landscapes and the ways they were framed in the art historical discourse. I argue that the canon of American landscape photography is the subject matter of Mann’s landscapes, and that her work stands in for a wider project: demonstrating that there is no landscape per se, nor ever was. Moreover, by analyzing the discourse surrounding Mann’s landscapes, this study highlights the patriarchal biases and intra-geographical hierarchy of symbolic meanings between the US regions that underlie the canon of American landscape photography.

  12. The Contributions of Immigrants to American Culture.

    Science.gov (United States)

    Hirschman, Charles

    2013-01-01

    The standard account of American immigration focuses on the acculturation and assimilation of immigrants and their children to American society. This analysis typically ignores the significant contributions of immigrants to the creation of American culture through the performing arts, sciences, and other cultural pursuits. Immigrants and their children are not born with more creative talents than native-born citizens, but their selectivity and marginality may have pushed and pulled those with ability into high-risk career paths that reward creative work. The presence of large numbers of talented immigrants in Hollywood, academia, and the high-tech industries has pushed American institutions to be more meritocratic and open to innovation than they would be otherwise.

  3. Transfusion medicine in American undergraduate medical education.

    Science.gov (United States)

    Karp, Julie K; Weston, Christine M; King, Karen E

    2011-11-01

    Blood transfusion is the most common procedure performed in American hospitals, and transfusions are commonly ordered by physicians without formal training in transfusion medicine. Several transfusion medicine curricula have been proposed, including those developed through the Transfusion Medicine Academic Awards (TMAA). To our knowledge, no comprehensive study has assessed how transfusion medicine is incorporated into undergraduate medical education. We conducted an online survey to determine the manner in which transfusion medicine is incorporated into American undergraduate medical education. The survey was e-mailed to administrators of medical education at all of the 129 American medical schools accredited by the Association of American Medical Colleges. Eighty-six (67%) of the 129 identified medical school administrators responded. Seventy-one (83%) of the 86 administrators reported that their undergraduate medical education curriculum provides didactic lectures in transfusion medicine, with 48% of medical schools providing 1 or 2 hours of lecture-based instruction. A minority reported small group sessions devoted to transfusion medicine topics. While a slim majority reported the availability of transfusion medicine electives, only one of 84 administrators reported that such a rotation is required. Seventy-six of 83 (92%) administrators were unfamiliar with either the 1989 or the 1995 TMAA transfusion medicine curricula. Transfusion medicine content in American undergraduate medical education is variable and the influence of the TMAA program on contemporary medical school curricula is questionable. Future efforts in this area should focus on standardizing and improving undergraduate medical education in transfusion medicine. © 2011 American Association of Blood Banks.

  4. A Foucauldian Theory of American Islamophobia

    Directory of Open Access Journals (Sweden)

    SHYAM K. SRIRAM

    2016-12-01

    Full Text Available With the emergence of ISIS andAmerican public furor over allowing Syrian refugees safe haven, Muslim Americans find themselves once again in the cross-hairs of a nation obsessed with searching for answers and someone to blame. I argue that the premise behind American anti-Muslim sentiment is rooted in two of Michel Foucault’s concepts -“biopower” and “pastoral power.” This article is divided in two halves. In the first, I argue that American nationalism is articulated in a unique way, particularly through “pastoral power.” In conjunction with an “imagined” American nationhood (Anderson 1983, it has created a state that is often viewed as secular, but is quite Christian ideologically and structurally. Drawing on Göle (1996, I surmise that the Western “culture of confession,” an extension of pastoral power, is incompatible with Islam – or at least is viewed as such. In the second half, I present my main argument towards a new understanding of Foucault’s (1990 biopower in the context of the sovereign and its ability to designate who is “sacred,” a la Agamben (1998. I suggest that a new evaluation of Agamben (1998 should be undertaken to account for the renewed racialization of and discrimination towards American Muslims.

    Amend, Kandace; Hicks, David; Ambrosone, Christine B

    2006-09-01

    Disparities exist between African-American and European-American women in the incidence and nature of breast cancer. African-American women are more often diagnosed with breast cancer at an earlier age and with more aggressive disease, characterized by higher grade and negative estrogen and progesterone receptor status. Recent findings reveal specific gene expression patterns associated with the more aggressive breast cancers observed in African-American women. An overview of the current literature about racial differences in breast cancer prompts questions for future research to elucidate causes for the apparent disparities in tumor biology.

  7. American Exceptionalism and the American Surgical Association: The Rise of Surgery in the United States.

    Science.gov (United States)

    Rutkow, Ira; Lillemoe, Keith D

    2018-04-01

    To explore use of the notion of American exceptionalism by fellows of the American Surgical Association (ASA) (1880 through World War I) and how this proved instrumental in the rise of surgery in the United States. American exceptionalism is the belief that the United States is innately different from other nations because of its economic, geographic, political, religious, and social foundations. Although, currently, the concept of American exceptionalism implies superiority, in its original 19th century connotation, the idea referred to the distinctive character of America as a free nation. An analysis of published literature along with unpublished documents to provide new knowledge and unique insight into the use of American exceptionalism by members of the ASA as they promoted their specialty. Beginning with Samuel Gross's desire that the organization he founded represent "the genius of our republican institutions," to Frederick Dennis's declaration that "American surgery eclipses all other nations because of the wonderful adaptability of the American mind," plus Lewis Pilcher's explanation of how the "stimulating climate, prevailing religious tone, regard for learning, and pride of citizenship are the fruit of the American mind when turned to surgical problems," and ending with Edmond Souchon's 106 page article in the Transactions on surgical firsts, the ASA was the avenue that helped the nation's surgeons define and defend themselves. Use of the concept of American exceptionalism by fellows of the ASA was a key factor in the development of surgery in the United States.

  8. Attitudes of Mexican Americans toward irregular immigration.

    Science.gov (United States)

    Polinard, J L; Wrinkle, R D; Garza, R D

    1984-01-01

    This inquiry focuses on the attitudes of 314 Mexican Americans toward issues relating to current US immigration policy. Telephone and personal interviews were conducted in Hidalgo and Travis counties, Texas, with Mexican-Americans. Virtually all respondent groups oppose an increased rate of immigration, consider illegal immigration to be an important problem, support stricter enforcement of immigration laws, and believe that undocumented workers take jobs no one else wants. Half of the respondents identify illegal immigration as a regional rather than a personal problem. At the same time, the data suggest significant differences in both direction and intensity of attitudes between Mexican Americans of different generations, income, occupational levels, and region. There is general opposition to the requirement of a national identity card, but widespread support for penalizing employers of undocumented workers and for granting amnesty to undocumented workers. These findings allow an examination of the extent to which the Mexican American leadership, which has been overwhelmingly opposed to the Simpson-Mazzoli bill, accurately reflects the views of the Mexican American people. The leadership and the population at large agree on 2 of the 3 issues, amnesty and the national identity card, but disagree on employer sanctions. 1st, it may be that the leadership holds the kinds of jobs for which undocumented workers are unlikely to compete, so they may not feel threatened. 2nd, they may feel that instituting employer sanctions will create incentives for employers to discriminate in their hiring practices against all Latino-looking job applicants. Non-elite Mexican Americans who support employer sanctions may believe that the only way they can compete for jobs is to make it impossible for elites to be hired. Both groups appear to fear that, regardless of the specifics of immigration reform, Mexican Americans are likely to encounter increased discrimination in the job market.

  9. Understanding Tobacco Use Onset Among African Americans.

    2016-04-01

    Compared to the majority of non-Hispanic white ("white") cigarette smokers, many African American smokers demonstrate a later age of initiation. The goal of the present study was to examine African American late-onset smoking (ie, regular smoking beginning at age 18 or later) and determine whether late-onset (vs. early-onset) smoking is protective in terms of quit rates and health outcomes. We used data from the National Survey of Midlife Development in the United States (MIDUS) because the wide age range of participants (20-75 at baseline) allowed the examination of smoking cessation and mortality incidence across the lifespan. Consistent with previous research, results indicated a later average age of smoking onset among African Americans, compared to whites. Disentangling effects of race from age-of-onset, we found that the cessation rate among late-onset African American smokers was 33%, whereas rates for early-onset African American smokers and early- and late-onset white smokers ranged from 52% to 57%. Finally, results showed that among white, low-socioeconomic status (SES) smokers, the hazard rate for mortality was greater among early- versus late-onset smokers; in contrast, among African American smokers (both low- and high-SES) hazard rates for mortality did not significantly differ among early- versus late-onset smokers. Although late (vs. early) smoking onset may be protective for whites, the present results suggest that late-onset may not be similarly protective for African Americans. Tobacco programs and regulatory policies focused on prevention should expand their perspective to include later ages of initiation, in order to avoid widening tobacco-related health disparities. This study indicates that late-onset smoking is not only the norm among African American adult smokers, but that late- versus early-onset smoking (ie, delaying onset) does not appear to afford any benefits for African Americans in terms of cessation or mortality. These results

  10. Chinese/American Physicists: A Transnational History

    Science.gov (United States)

    Wang, Zuoyue

    2011-03-01

    As part of a broader project on ``Chinese/American Scientists: Transnational Science during the Cold War and Beyond,'' this paper examines the movements of American-trained Chinese physicists following the founding of the People's Republic of China in 1949. While a majority of these physicists chose to stay in the US (the ``stayees''), a number went back to China in the 1950s (the ``returnees'') against many obstacles during the McCarthy era. After the reopening of US-China relations in the 1970s, the two groups joined hands in promoting China-US scientific and educational exchanges, leading eventually to the coming to the US of a new generation of Chinese physics students and the return to China of some of the original ``stayees.'' This transnational history of Chinese/American physicists aims to illustrate the nature and extent of the Americanization of international science and the internationalization of American science in the post-World War II era. This work was supported in part by the National Science Foundation under Grant No. SES-1026879.

    Full Text Available Abstract Background Since African-Americans have twice the prevalence of cytomegalovirus (CMV infections as age-matched Caucasians we sought to determine the ages and possible sources of infection of African-American children. Methods Subjects were 157 African-American healthy children and adolescents and their 113 household adults in Richmond VA. Families completed a questionnaire, provided saliva for antibody testing, and adolescents were interviewed regarding sexual activity. Results Regardless of age CMV seropositivity was not associated with gender, breast feeding, health insurance, sexual activity, or household income, education, or size. In the final regression model, prior CMV infection in adults was over two-fold higher than in children (chi-square = 18.8, p Conclusion We observed that African-American children had CMV seroprevalence rates by age 20 years at less than one-half of that of their adult mothers and caregivers. Sibling-to-sibling transmission was a likely source of CMV infections for the children. The next generation of African-American women may be highly susceptible to a primary CMV infection during pregnancy and may benefit from a CMV vaccine.

    2007-01-01

    To determine the characteristics of Arab Americans receiving treatment and to compare them with individuals of other ethnic groups. We used admission data (FY2005) for Michigan publicly funded substance abuse treatment (N=69,989). Arab American ethnicity (n=224 or 0.3% of admissions) was defined by codes for race, ethnicities or primary language of Arabic (n=21). Other ethnicities examined were American Indian, Hispanic, African American, and White. The number of Arab American admissions was lower than expected for the population (RR=0.25). Admissions were concentrated (81%) in metropolitan Detroit as is the community (82%, RR=.99), unlike other ethnicities. Primary drugs of abuse were alcohol (34.8%), marijuana (17.9%), heroin (17.4%) and crack cocaine (15.6%). Mean duration of use (11.2 yrs) was significantly lower than for other ethnicities. Arab American admissions were predominately male (76.3%), unemployed (62.1%) and with criminal justice involvement (58%), similar to other ethnicities. Using administrative database has its limits and may misclassify ethnicities. Based upon the available data, it appears that Arab Americans accounted for a small percentage of admissions to publicly funded substance abuse treatment in Michigan. Most of the admissions listed English as the primary language, raising concern that language may be a barrier to entry. Admission profiles were generally similar across ethnicities, except that Arab Americans were entering treatment after shorter duration of use. These data can inform development of treatment programs and outreach efforts.

  5. Implicit bicultural identity among Mexican American and Asian American college students.

    Science.gov (United States)

    Devos, Thierry

    2006-07-01

    Contemporary research on ethnic identity, acculturation, and cultural orientation suggests that, at least under some circumstances, individuals can successfully internalize or identify with more than one culture. Previous research on multicultural identity has relied almost exclusively on self-report measures. Using the Implicit Association Test (IAT), the present research examined to what extent Mexican American and Asian American college students identified with American culture and with their culture of origin. Results indicated that Mexican American and Asian American participants strongly and equally identified with both cultures. The present research provides firm evidence for a bicultural identity through assessments of thoughts that cannot be consciously controlled. Patterns of bicultural identification obtained on implicit measures were not the product of deliberate responses to normative demands or conscious attempts to convey a particular self-image.

  6. Is the American Zebu really Bos indicus?

    Directory of Open Access Journals (Sweden)

    Meirelles Flávio V.

    1999-01-01

    Full Text Available The American continent was colonized in the 16th century by Europeans who first introduced cattle of Bos taurus origin. Accounts register introduction of Bos indicus cattle into South America in the 19th and continuing through the 20th century, and most reported imports were males derived from the Indian subcontinent. In the present study we show, by using mitochondrial DNA (mtDNA polymorphism, major participation of matrilineages of taurus origin in the American Zebu purebred origin, i.e., 79, 73 and 100% for the Nellore, Gyr and Brahman breeds, respectively. Moreover, we have created a restriction map identifying polymorphism among B. taurus and B. indicus mtDNA using three restriction enzymes. Results are discussed concerning American Zebu origins and potential use of this information for investigating the contribution of cytoplasmic genes in cattle production traits.

  7. Depression among older Mexican American caregivers.

    Hernandez, Ann Marie; Bigatti, Silvia M

    2010-01-01

    The authors compared depression levels between older Mexican American caregivers and noncaregivers while controlling for confounds identified but not controlled in past research. Mexican American caregivers and noncaregivers (N = 114) ages 65 and older were matched on age, gender, socioeconomic status, self-reported health, and acculturation. Caregivers reported higher scores on the Center for Epidemiologic Studies Depression scale (CES-D) and were more likely to score in the depressed range than noncaregivers. In a regression model with all participants, group classification (caregiver vs. noncaregiver) and health significantly predicted CES-D scores. A model with only caregivers that included caregiver burden, self-rated health, and gender significantly predicted CES-D scores, with only caregiver burden entering the regression equation. These results suggest that older Mexican American caregivers are more depressed than noncaregivers, as has been found in younger populations. (c) 2009 APA, all rights reserved.

  8. Is There Really A North American Plate?

    Science.gov (United States)

    Krill, A.

    2011-12-01

    Lithospheric plates are typically identified from earthquake epicenters and evidence such as GPS movements. But no evidence indicates a plate boundary between the North American and South American Plates. Some plate maps show them separated by a transform boundary, but it is only a fracture zone. Other maps show an "undefined plate boundary" or put no boundary between these two plates (check Google images). Early plate maps showed a single large American Plate, quite narrow east of the Caribbean Plate (Le Pichon 1968, Morgan 1968). The North and South American Plates became established by the leading textbook Earth (Press & Siever 1974). On their map, from a Scientific American article by John Dewey (1972), these new plates were separated by an "uncertain plate boundary." The reasons for postulating a North American Plate were probably more psychological than geological. Each of the other continents of the world had its own plate, and North American geologists naturally wanted theirs. Similarly, European geographers used to view Europe as its own continent. A single large plate should again be hypothesized. But the term American Plate would now be ambiguous ("Which plate, North or South?") Perhaps future textbook authors could call it the "Two-American Plate." Textbook authors ultimately decide such global-tectonic matters. I became aware of textbook authors' opinions and influence from my research into the history of Alfred Wegener's continental drift (see Fixists vs. Mobilists by Krill 2011). Leading textbook author Charles Schuchert realized that continental drift would abolish his cherished paleogeographic models of large east-west continents (Eria, Gondwana) and small oceans (Poseiden, Nereis). He and his junior coauthors conspired to keep drift evidence out of their textbooks, from the 1934-editions until the 1969-editions (Physical Geology by Longwell et al. 1969, Historical Geology by Dunbar & Waage 1969). Their textbooks ruled in America. Textbooks

    Sumar, Julio B

    2013-01-10

    Intraspecific and interspecific embryo transfer in domestic South American camelids is developing into a well-established technique. Reports reveal many benefits of using reproductive biotechnologies to allow rapid propagation of alpacas and llamas of high genetic merit (e.g., high fiber quality, preserve color variation). The objective of this review is to provide up-to-date information about embryo transfer in domestic South American camelids. Specific information is provided on criteria for male selection, donor and recipient synchronization, the practice of single- vs. super-ovulation protocols, embryo recovery and transfer techniques, advances in cryopreservation of embryos, results of intra- and inter-specific transfer, and the future of the embryo transfer in domestic South American camelids.

  11. The myth of meritocracy and African American health.

    Science.gov (United States)

    Kwate, Naa Oyo A; Meyer, Ilan H

    2010-10-01

    Recent theoretical and empirical studies of the social determinants of health inequities have shown that economic deprivation, multiple levels of racism, and neighborhood context limit African American health chances and that African Americans' poor health status is predicated on unequal opportunity to achieve the American Dream. President Obama's election has been touted as a demonstration of American meritocracy-the belief that all may obtain the American Dream-and has instilled hope in African Americans. However, we argue that in the context of racism and other barriers to success, meritocratic ideology may act as a negative health determinant for African Americans.

  12. The management of hypertension in African Americans.

    Science.gov (United States)

    Ferdinand, Keith C; Armani, Annemarie M

    2007-06-01

    The prevalence of hypertension in blacks in the United States is among the highest in the world. Compared with whites, blacks develop hypertension at an earlier age, their average blood pressures are much higher and they experience worse disease severity. Consequently, blacks have a 1.3 times greater rate of nonfatal stroke, 1.8 times greater rate of fatal stroke, 1.5 times greater rate of heart disease death, 4.2 times greater rate of end-stage kidney disease, and a 50% higher frequency of heart failure; overall, mortality due to hypertension and its consequences is 4 to 5 times more likely in African Americans than in whites. The increased prevalence of hypertension and excessive target organ damage is due to a combination of genetic and, most likely, environmental factors. There are no clinical trial data at present to suggest that lower-than-usual BP targets should be set for high-risk demographic groups such as African Americans. The primary means of prevention and early treatment of hypertension in African Americans will be the appropriate use of lifestyle modification. The International Society of Hypertension in Blacks guidelines realize that most patients will require combination therapy, many of them first-line, to reach appropriate BP goals. Although certain classes and combinations of antihypertensive agents have been well-established to be effective, the choice of drugs for combination therapy in African American patients may be different. Within the African American group, the responsiveness to monotherapy with ACE inhibitors, angiotensin receptor blockers, and beta blockers may be less than the responsiveness to diuretics and calcium channel blockers, but these differences are corrected when diuretics are added to the neurohormonal antagonists. Of note, African American patients with systolic BP >15 mm Hg or a diastolic BP >10 mm Hg above goal should be treated with first-line combination therapy.

    2008-12-01

    The USA is spreading their political, military, economic, scientific, artistic and cultural mission throughout the world. The aim of this paper is to bring to the attention the Americanization of the Croatian language particularly evident in the newly adopted language manners, in teenage language, in specialist languages, in the field of advertising and in political correctness. The spread of Americanization of the Croatian language has both negative and positive effects. Positive effects can be regarded as enrichment of the Croatian language, whereas the negative ones endanger its deep structure. Positive effects should be supported and negative minimized through the cooperation between experts in linguistics and politics.

  14. American Samoa Initial Technical Assessment Report

    Energy Technology Data Exchange (ETDEWEB)

    Busche, S.; Conrad, M.; Funk, K.; Kandt, A.; McNutt, P.

    2011-09-01

    This document is an initial energy assessment for American Samoa, the first of many steps in developing a comprehensive energy strategy. On March 1, 2010, Assistant Secretary of the Interior Tony Babauta invited governors and their staff from the Interior Insular Areas to meet with senior principals at the National Renewable Energy Laboratory (NREL). Meeting discussions focused on ways to improve energy efficiency and increase the deployment of renewable energy technologies in the U.S. Pacific Territories. In attendance were Governors Felix Camacho (Guam), Benigno Fitial (Commonwealth of the Northern Mariana Islands), and Togiola Tulafono, (American Samoa). This meeting brought together major stakeholders to learn and understand the importance of developing a comprehensive strategic plan for implementing energy efficiency measures and renewable energy technologies. For several decades, dependence on fossil fuels and the burden of high oil prices have been a major concern but never more at the forefront as today. With unstable oil prices, the volatility of fuel supply and the economic instability in American Samoa, energy issues are a high priority. In short, energy security is critical to American Samoa's future economic development and sustainability. Under an interagency agreement, funded by the Department of Interior's Office of Insular Affairs, NREL was tasked to deliver technical assistance to the islands of American Samoa. Technical assistance included conducting an initial technical assessment to define energy consumption and production data, establish an energy consumption baseline, and assist with the development of a strategic plan. The assessment and strategic plan will be used to assist with the transition to a cleaner energy economy. NREL provided an interdisciplinary team to cover each relevant technical area for the initial energy assessments. Experts in the following disciplines traveled to American Samoa for on-island site assessments: (1

  16. Transnational citizenship: Latin Americans in Portugal

    Directory of Open Access Journals (Sweden)

    Beatriz Padilla

    2014-09-01

    Full Text Available This article is a reflection upon the exercising of transnational citizenship as a consequence of international migration, applied to Latin Americans resident in Portugal. In order to do this we have adopted the concept of transnational citizenship, as its malleability allows us to consider the whole concept of countries of origin and destination and the influence of bilateral and international relations. We ask how transnational citizenship is exercised in the European Union, Ibero-American and, particularly, Portuguese spaces, and whether it is affected by the economic crisis in Europe and, in particular, Portugal, by analysing the cases of Argentines, Brazilians and Uruguayans living in Portugal.

    Globalization prompts remote acculturation toward U.S. culture in Jamaica; this study used a bioecological systems approach to examine its proximal impact on nutrition through U.S. cable TV consumption, and maternal influences in the home. Overall, 330 randomly selected adolescent-mother dyads from schools in Kingston, Jamaica (M adolescent_age  = 13.8 years, SD adolescent_age  = 1.8) completed questionnaires reporting American identity and behavioral preferences, daily time spent watching U.S.-produced TV programs, and frequency of eating unhealthy foods. Actor-partner interdependence models revealed that girls' American identity/behavior directly predicted their unhealthy eating, whereas girls' mothers and boys' American identity/behavior indirectly predicted unhealthy eating as mediated by their U.S. TV hours. Additionally, mothers' American identity/behavior predicted daughters' unhealthy eating as mediated by mothers' U.S. TV hours. Remote acculturation theory may facilitate more targeted research and prevention/intervention. © 2017 The Authors. Child Development © 2017 Society for Research in Child Development, Inc.

  20. Avaliação da aplicabilidade de um padrão cefalométrico norte-americano em pacientes brasileiros submetidos à cirurgia ortognática Evaluation of the applicability of a North American cephalometric standard to Brazilian patients subjected to orthognathic surgery

    undergone surgery of the maxilla and mandible with the cephalometric standard used as guidance in planning the cases. METHODS: The tracings were generated by the Dolphin Imaging 9.0 computer program from scanned lateral cephalograms in which 48 dental, osseous and tegumentary landmarks were defined. Thus, were obtained 26 linear and angular cephalometric measurements to be compared with normative values, considering sexual dimorphism and possible modifications to the treatment plan to meet the individual needs of each case, as well as any possible ethnic and racial differences. The sample data were compared with the standard using Student's t-test means and standard deviations. RESULTS: The results showed that for males, the sample means were significantly different from the standard in five of the measurements, while for women, nine were statistically different. However, despite the similarity of the means of most measurements in both genders, the data showed marked individual variations. CONCLUSIONS: An analysis of the results suggests that the North American cephalometric standard is applicable as a reference for planning orthodontic-surgical cases of Brazilian patients, provided that consideration is given to variations in the individual needs of each patient.

  3. Black and Korean: Racialized Development and the Korean American Subject in Korean/American Fiction

    Directory of Open Access Journals (Sweden)

    Jeehyun Lim

    2013-09-01

    Full Text Available This article examines the representation of the encounters and exchanges between Asian and black Americans in Sŏk-kyŏng Kang’s “Days and Dreams,” Heinz Insu Fenkl’s Memories of My Ghost Brother, and Chang-rae Lee’s A Gesture Life. While one popular mode of looking at Asian and black Americans relationally in the postwar era is to compare the success of Asian American assimilation to the failure of black Americans, Lim argues that such a mode of comparison cannot account for the ways in which Asian American racialization takes places within the global currents of militarism and migration. Against the popular view that attributes Asian American success to cultural difference, Lim relies on political scientist Claire Kim’s understanding of culture as something that is constructed in the process of racialization to explore how the above texts imagine the terms of comparative racialization between black and Asian Americans. The black-Korean encounters in these texts demand a heuristic of comparative racialization that goes beyond the discussion of the black-white binary as a national construct and seeks the reification and modification of this racial frame as it travels along the routes of US military and economic incursions in the Pacific. Lim suggests that the literary imagining of black-Korean encounters across the Pacific illustrates race and racialization as effects of a regime of economic development that is supported by military aggression.

  4. Lactose intolerance and health disparities among African Americans and Hispanic Americans: an updated consensus statement.

    Dairy foods contribute nine essential nutrients to the diet including calcium, potassium and vitamin D; nutrients identified by the 2010 Dietary Guidelines for Americans as being "of public health concern" within the U.S. population. Milk and milk product intake is associated with better diet quality and has been associated with a reduced risk of chronic diseases or conditions including hypertension, cardiovascular disease, metabolic syndrome, Type 2 Diabetes and osteoporosis. Some research also indicates dairy food intake may be linked to reduced body fat, when accompanied by energy-restriction. On average, both African Americans and Hispanic Americans consume less than the recommended levels of dairy foods, and perceived or actual lactose intolerance can be a primary reason for limiting or avoiding dairy intake. True lactose intolerance prevalence is not known because healthcare providers do not routinely measure for it, and no standardized assessment method exists. Avoiding dairy may lead to shortfalls of essential nutrients and increased susceptibility to chronic disease. This updated Consensus Statement aims to provide the most current information about lactose intolerance and health, with specific relevance to the African American and Hispanic American communities. Topics covered include diagnostic considerations, actual and recommended dairy food intake and levels of consumption of key dairy nutrients among African Americans and Hispanic Americans; prevalence of self-reported lactose intolerance among various racial/ethnic groups; the association between dairy food intake, lactose intolerance and chronic disease; and research-based management recommendations for those with lactose intolerance.

  20. Does American bioethics speak with one voice?

    Science.gov (United States)

    Doucet, Hubert

    2009-12-01

    Many international organizations and countries have adopted the principles of American bioethics as their own principles. However, further analysis of what is going on in the United States shows that what we have come to call principlism is only one expression among many other health care ethics approaches that are found in the U.S. The first section of the text presents American bioethics from the point of view of principlism, the main focus being the creation of this vision, and its meaning. The second section examines, first of all, the critiques that from the beginning have been addressed to this approach; and secondly, other visions developed as much in response to the limits intrinsic to principlism as to the major changes that drive the American health system. In the third section, I will attempt to indicate that the real challenge of American bioethics is not a consequence of the tension existing between principlism and the other approaches, but that it arises in the political domain: the polarization between liberals and conservatives.

    Science.gov (United States)

    Liem, R; Lim, B A; Liem, J H

    2000-02-01

    This study examined the emotion experience of Asian Americans in relation to respondents' orientation to acculturation: Assimilation, Integration, Separation, or Marginalization (J. W. Berry, 1980). Ego- versus other-focused emotion experiences (H. R. Markus & S. Kitayama, 1991) and attention and valence, 2 stages in P. C. Ellsworth's (1994) model of emotion appraisal, were used to investigate the relation between acculturation and affect. Asian Americans most and least assimilated to the dominant Anglo American culture were expected to exhibit emotion responses correspondingly similar to and different from those of Anglo Americans. Those with a bi-cultural or integrationist trajectory should occupy a middle ground in terms of emotional experience. Compared with the appraisal process, ego- versus other-focused emotions, mediated in part by one's self-construal (e.g., independent or interdependent), were more strongly associated with acculturation orientation in the expected directions. The implications of recognizing the influence of acculturation on the emotional meaning of life encounters of newcomers are discussed in light of community psychology and clinical practice.

  12. CONTEMPORARY CHALLENGES IN LATIN AMERICAN ADMINISTRATIVE JUSTICE

    Directory of Open Access Journals (Sweden)

    R. Perlingeiro

    2016-01-01

    Full Text Available This study consists of a critical comparative analysis of the administrative justice systems in eighteen Latin-American signatory countries of the American Convention on Human Rights (Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, El Salvador, Ecuador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, the Dominican Republic, Uruguay, and Venezuela. According to this article, the excessive litigation in Latin-American courts that has seriously hampered the effectiveness of the administrative justice systems may be explained as follows: as former Iberian colonies, the aforementioned countries have a Continental European legal culture originating in civil law but nevertheless have improperly integrated certain aspects of the unified judicial system (generalized courts typical of administrative law in common-law countries. This situation, according to the author, could be rectified through strengthening the public administrative authorities with respect to their dispute-resolution and purely executive functions by endowing them with prerogatives to act independently and impartially, oriented by the principle of legality understood in the sense of supremacy of fundamental rights, in light of the doctrine of diffuse conventionality control adopted by the InterAmerican Court of Human Rights.

    Full Text Available The article shows that over the past decade and a half there have been significant changes in the international situation in Latin America, which affected all the main areas of external relations in the region. The interaction between the Latin American countries moved forward, which was reflected in the formation and development of new structures, such as UNASUR, ALBA, SELAC, and the Pacific Alliance. China has dramatically expanded its presence in the region, which was manifested in the growth of trade and Chinese investment, and the transition from the level of bilateral cooperation to multilateral format. The cooperation between Latin America and Russia has risen on a higher level, which was manifested in the expansion of trade and economic ties and collaboration of certain Latin American integration groupings with the EAEC.

All these factors combine to expand the range of external relations of Latin American and Caribbean countries and prove the changing role of Latin America in the system of global relations.
