    In der vorliegende Diplomarbeit werden die Werke der amerikanischen Künstlerin Georgia O’Keeffe (1887-1986) behandelt. Das Hauptaugenmerk liegt dabei auf den Arbeiten aus ihren frühen Jahre zwischen 1915 und 1920. Die Kohlezeichnungen, Aquarelle, Ölgemälde und Skulpturen werden auf europäische Vorbilder untersucht. Im Hinblick auf eventuell gegebene europäische Einflüsse soll eruiert werden, ob das der Künstlerin von Alfred Stieglitz, ihrem Förderer, Kunsthändler und späterem Ehemann, verliehene Prädikat „genuin American“ heute noch haltbar ist. In der bisherigen Forschung werden die Arbeiten von O’Keeffe vorwiegend in einen amerikanischen Kontext gestellt. Nur wenn es aufgrund gesicherter Tatsachen unvermeidlich erscheint, werden von den vorwiegend amerikanischen AutorInnen auch Verbindungen zu europäischen Künstlern und Kunstströmungen aufgezeigt. Der Inhalt der vorliegenden Schrift soll über die bis dato angestellten Vergleiche mit der europäischen Kunst hinausgehen. Die Forschung zum Frühwerk von O’Keeffe ist noch relativ jung. Sie setzte erst nach dem Tod der Künstlerin in den späten 1980er Jahren ein, als die Werke aus ihrer Orientierungsphase wieder an die Öffentlichkeit gelangten. Daher gibt es auf diesem Gebiet noch viel zu entdecken. Zum einen werden hier Einflüsse untersucht, die in der bisherigen Literatur bereits anerkannt werden. Dies sind der Jugendstil, der Symbolismus und die Lehre ihres Professors Arthur W. Dow. Diese Vergleiche werden anhand neuer Beispiele abermals angestellt und dienen zum besseren Verständnis von O’Keeffes Werken sowie den darauf folgenden Gegenüberstellungen mit der europäischen Avantgarde. Auch wurde in der Forschung bereits ein möglicher Zusammenhang einer Aktserie der Künstlerin mit Aktzeichnungen von Auguste Rodin erwähnt. Da ich hier aber zu einem anderen Schluss komme, wird auch diese Beziehung erneut aufgezeigt. Im Hauptteil wird der Frage nachgegangen, ob O’Keeffe in der Phase ihres Suchens nach einem eigenen künstlerischen Ausdruck auch von europäischen Avantgardeströmungen beeinflusst wurde. Dahingehend werden ihre Arbeiten Werken von Künstlern des Kubismus, des Orphismus und des Futurismus gegenübergestellt. Neben der direkten Beeinflussung durch europäische Modernisten finden deren Neuerungen aber auch auf Umwegen Eingang in das Werk der amerikanischen Künstlerin. O’Keeffe absorbierte die Ideen der Europäer gefiltert durch die Kunst ihrer Landsleute, die zuvor in Europa studiert und die neuesten künstlerischen Ansichten in ihr Werk übernommen hatten. Es wird aufgezeigt, dass O’Keeffe sich wohl am Kubismus versucht hatte, dieser aber kaum Einzug in ihr reifes Werk gehalten hat. Auch der Orphismus oder dessen amerikanische Version, der Synchromismus, wurde von O’Keeffe kurzzeitig aufgegriffen und verarbeitet. Der Futurismus hingegen spielte im Frühwerk der Künstlerin eine bedeutendere Rolle und trägt seine Spuren durch ihr gesamtes Oeuvre. Freilich ist das Ergebniss aufgrund der sozialen und politischen Verhältnisse in den USA ein anderes als das der europäischen Avantgardisten. Im letzten Kapitel werden O’Keeffes Werke denen der deutschen Expressionisten gegenüber gestellt. Ein Einfluss der in der Forschung zu O’Keeffe bisher gänzlich ignoriert wurde. Es wird an dieser Stelle veranschaulicht, dass O’Keeffe sich auch mit dieser Kunstströmung auseinandersetzte. Teils griff sie die formalen und stilistischen Elemente der deutschen Künstler auf und verwarf sie nach kurzer Zeit wieder. Teils fanden diese Eingang in ihren persönlichen Stil und somit auch in ihr reifes Werk. Zusammenfassend kann gesagt werden, dass europäische Künstler und Kunstrichtungen, sei es auf direktem oder indirektem Weg, das Werk von O’Keeffe beträchtlich beeinflusst haben. Daher ist meiner persönlichen Ansicht nach die Bewertung der Künstlerin als genuin amerikanisch nicht haltbar

    The lipid compositíon and fluidity of jejunal brush-border membrane vesicles (BBMV) have been studied in spontaneously hypertensive rats (SHR) and normotensive Wistar Kyoto (WKY) rats. The activities of both Na+-dependent D-glucose cotransport and Na+-H antiport have also been determined. A significan! increase in the level of free cholesterol was observed in jejunal BBMV from SHR compared to WKY rats. Since phospholipid values did not change in either group of animals, a significan! enhancement in the free cholesterol/phospholipid ratio was observed in SHR. A decrease in the levels of phosphatidylethanolamine together with an increase in the values of phos­ phatidylserine was observed in hypertensive rats. Although the content of phosphatidylcholine (PC) and sphingomyelin (SM) was not singificantly altered in SHR, the ratio PC/SM significantly increased in these animals when compared to WKY rats. The majar fatty acids present in bursh-border membranes prepared from SHR and WKY rats were palmitic (16:0), stearic (18:0), oleic (18:1, n-9) and linoleic (18:2, n-6), and the fatty acid composition was not modified by the hypertension. A decreased fluorescence polarization, i.e., increased membrane ftuidity, was observed in SHR, which was not correlated to the increased ratio of cholesterol/phospholipid found in the brush-border membrane isolated from these animals. These structural changes found in SHR were associated to an enhancement in both Na+ -dependent D-glucose transport and Na+-H+ antiport activíty in the jejunal BBMVof SHR

    The effects of two monounsaturated fatty acid (MUFA) oils, olive oil (OO)and high-oleic sunflower oil (HOSO), with high content in oleic acid butdiffering in their non-fatty acid fraction, on brush-border membrane(BBM) lipid composition and fluidity and on mucosal enzyme activitiesof rat jejunum were studied. Animals were given semipurified diet withlinoleic acid to prevent essential fatty acid deficiency (control group)or semipurified diet containing 10% of either OO or HOSO for 12weeks. There was a significant decrease in the content of jejunalBBM phospholipids together with an increase in the level of freecholesterol in both oil-fed rats, when compared to controlgroup. Although the increase in the BBM free cholesterol levelwas not statistically significant in HOSO-fed rats, a significantdecrease in the phospholipid/free cholesterol ratio was found inboth OO and HOSO-fed animals compared to control group. Rat jejunalBBM had a high level of free fatty acids which was increased in BBMisolated from OO and HOSO-fed animals. There was no statisticalsignificant difference in the phospholipid distribution between thecontrol and the OO group. However, HOSO-fed animals showed the lowestlevel of phosphatidylethanolamine together with the highestphosphatidylcholine content and the phosphatidylcholine/sphingomyelinratio. The fatty acid pattern of jejunal BBM lipids was modifiedaccording to the major fatty acids in the oils. There was a decreasein both stearic acid (18:0) and linoleic acid (18:2 n-6), togetherwith an increase in oleic acid (18:1 n-9) in jenunal BBM isolatedfrom both oil experimental groups. All these results were accompaniedby a significant increase in the BBM fluidity (as assessed bysteady-state fluorescence polarization of diphenylhexatriene) isolatedfrom oil-fed rat, when compared to control group. OO and HOSO-fedanimals had the lowest activities of sucrase and maltase, whilealkaline phosphatase activity only was decreased in HOSO-fedanimals. The specific activity of maltase was not modified in anyexperimental rats. In summary, both MUFA oils induced similar effectson jejunal BBM lipid composition, fluidity, sucrase, maltase andlactase activities. Furthermore, HOSO intake resulted in a lowestalkaline phosphatase activity which was accompanied by changes inindividual phospholipid composition. All these results suggest thateffects of MUFA oils on jejunal BBM lipid composition and hydrolaseactivities are most likely due to the presence of high content ofoleic acid rather than other components contained in the non-fattyacid of olive oil

    BACKGROUND: Decreased food intake is a risk factor for relevant complications (e.g. infections, pressure ulcers), longer hospital stays, higher readmission rates, greater health care costs and increased patient mortality, particularly in frail hospitalized older adults who are malnourished or at risk of malnutrition. Nurses are called to improve this criticality, starting from accurately identify patients for malnutrition at hospital admission and effectively monitoring their food intake. OBJECTIVES: The primary aim was to identify reliable predictive indicators of reduced food intake at hospital admission. The secondary aims were to assess the adequacy of daily energy and protein intake and the impact of nutrient intake on patient outcomes. DESIGN: Prospective observational longitudinal study. SETTING: Internal Medicine Ward of an Academic Teaching University Hospital. PARTICIPANTS: Acute older adults who were malnourished or at risk of malnutrition (Nutritional Risk Score-2002\u202f 65\u202f3, middle-upper arm circumference\u2009<23.5\u202fcm or impaired self-feeding ability) at admission. METHODS: The effective energy and protein intake was monitored during the first 5\u202fdays of hospital stay by a photographic method and compared to the daily energy and protein requirement calculated by specific equations. Data on anthropometry, inflammation/malnutrition laboratory data and body composition (phase\u202fangle calculated using bioelectrical impedance analysis) were collected. RESULTS: Eighty-one subjects (age 81.5\u202f\ub1\u202f11.5\u202fyears) were enrolled. Mean energy intake was 669.0\u202f\ub1\u202f573.9\u202fkcal/day, and mean protein intake was 30.7\u202f\ub1\u202f25.8\u202fg/day. Over 60% of patients ingested\u2009 6450% of their calculated energy and protein requirements: these patients were older (p\u202f=\u202f0.026), had a lower middle-upper arm circumference (p\u202f=\u202f0.022) and total arm area (p\u202f=\u202f0.038), a higher C-reactive protein/albumin ratio and Instant Nutritional Assessment score (p\u202f<\u202f0.01), and experienced longer hospital stays (p\u202f 64\u202f0.04) and higher in-hospital and 30-day post-discharge mortality (p\u202f<\u202f0.001). In the multivariate analysis, lower middle-upper arm circumference, higher C-reactive protein/albumin ratio, and impaired self-feeding at admission were independently associated with critically reduced energy and protein intake. CONCLUSIONS: Middle-upper arm circumference, C-reactive protein/albumin ratio, and impaired self-feeding are easily obtainable indicators of impaired energy and protein intake and poor clinical outcomes. Such parameters should be adopted as screening criteria to assess the risk for critically reduced energy/protein intake in hospitalized older adults. These findings are relevant to improve clinical practice through the implementation of multidisciplinary strategies, given the adverse clinical outcomes related to hospital malnutrition

    Objective: To assess the Supervised Curricular Internship of the Nursing undergraduate course of two higher education institutions in the state of São Paulo based on specific skills described in the Brazilian National Curriculum Guidelines regarding preparation to the development of nursing care and management actions from the perceptions of professors, undergraduate students, and alumni. Method: Descriptive study in which a questionnaire was applied to 59 undergraduate students, 111 alumni, and 27 professors of a Nursing undergraduate course involved in the Supervised Curricular Internship in the analyzed institutions. Results: The perceptions of the actors involved in the development of management and care actions were positive, although part of the alumni pointed out that the Supervised Curricular Internship does not allow the students to: develop all the activities performed by the nursing team; work towards comprehensive health care; professional technical confidence; and interfere with the work dynamics. Conclusion: In the perception of those involved, the Supervised Curricular Internship is seen as positive and important in the training of students, as it introduces students into the professional reality of nurses. However, this discipline still needs structural changes, particularly in the perception of the alumni

    Occupation and skin cancer: the results of the HELIOS-I multicenter case-control study

    Get PDF
    <p>Abstract</p> <p>Background</p> <p>Non-melanoma skin cancer (NMSC) is the most frequent tumour among Caucasian populations worldwide. Among the risk factors associated with this tumour, there are host-related factors and several environmental agents. A greater likelihood of high exposure to physical agents (with the exception of solar radiation) and chemical agents depends on the work setting. Our objective is to evaluate the role of occupational exposures in NMSC, with special emphasis on risk factors other than solar radiation and skin type.</p> <p>Methods</p> <p>We analysed 1585 cases (1333 basal cell carcinoma (BCC) and 183 squamous cell carcinoma (SCC)) and 1507 controls drawn from the Helios-I multicenter study. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using logistic regression mixed models.</p> <p>Results</p> <p>For NMSC as a whole (both <it>histological types</it>), miners and quarrymen, secondary education teachers, and masons registered excess risk, regardless of exposure to solar radiation and skin type (OR 7.04, 95% CI 2.44–20.31; OR 1.75, 95% CI 1.05–2.89 and OR 1.54, 95% CI 1.04–2.27, respectively). Frequency of BCC proved higher among railway engine drivers and firemen (OR 4.55; 95% CI 0.96–21.57), specialised farmers (OR 1.65; 95% CI 1.05–2.59) and salesmen (OR 3.02; 95% CI 1.05–2.86), in addition to miners and quarrymen and secondary education teachers (OR 7.96; 95% CI 2.72–23.23 and OR 1.76; 95% CI 1.05–2.94 respectively). The occupations that registered a higher risk of <it>SCC (though not of BCC</it>) were those involving direct contact with livestock, construction workers not elsewhere classified (OR 2.95, 95% CI 1.12–7.74), stationary engine and related equipment operators not elsewhere classified (OR 5.31, 95% CI 1.13–21.04) and masons (OR 2.55, 95% CI 1.36–4.78).</p> <p>Conclusion</p> <p>Exposure to hazardous air pollutants, arsenic, ionizing radiations and burns may explain a good part of the associations observed in this study. The Helios study affords an excellent opportunity for further in-depth study of physical and chemical agents and NMSC based on matrices of occupational exposure.</p
