Diagnostic performance of gadobenate dimeglumine enhanced MR angiography of the iliofemoral and calf arteries: a large-scale multicenter trial
2007
OBJECTIVE. The purpose of this study was to compare gadobenate dimeglumine–enhanced MR angiography and unenhanced time-of-flight MR angiography for the detection of significant peripheral arterial occlusive disease using digital subtraction angiography as our reference standard. SUBJECTS AND METHODS. Two hundred seventy-two patients underwent MR angiography and digital subtraction angiography of the iliofemoral arteries. MR angiography was performed before (2D time-of-flight acquisitions) and after (spoiled gradient-echo acquisitions) the administration of 0.1 mmol/kg of gadobenate dimeglumine at 1–2 mL/s. Contrast-enhanced MR angiography and digital subtraction angiography of the calf arte…
Parental occupational exposure to organic solvents and anencephaly in Mexico
2009
Objective: To assess the relationship between parental occupational exposure to organic solvents, and the risk of anencephaly in Mexico. Methods: A case-control study was conducted based on the registers of the Epidemiological Surveillance System for Neural Tube Defects in Mexico; 151 cases of anencephaly of ≥20 weeks’ gestation were included. A control, born alive and without any apparent congenital malformations at birth, was selected for each case in the same maternity service in which the case was born. Information on occupational exposures, lifestyle habits, reproductive history, use of medicines, supplementation with multivitamins and folic acid, was obtained by a general questionnair…
Depression: Point-prevalence and sociodemographic correlates in a Buenos Aires community sample
2011
Abstract Background Since the current epidemiology of depression is not well documented in Latin America, we conducted a community-based survey study in Argentina. Methods The Beck Depression Inventory (BDI) and a general health questionnaire were completed by 1335 adult participants, representing most of the neighborhoods of Buenos Aires. Results Prevalence of high total BDI scores (≥ 13) indicating probable current clinically significant depression was 20.0% (women: 20.6%; men: 19.6%). Probable depression was associated with being unmarried and older, less educated, reporting recent stressors and significant medical illness. Limitations Sampling was cross-sectional and by convenience; pro…
Are Latin American cycling commuters 'at risk'? A comparative study on cycling patterns, behaviors, and crashes with non-commuter cyclists
2020
Abstract Introduction As part of the transformation of urban transportation dynamics, commuter cycling has acquired a high relevance as an alternative mode of transport in different countries, and Latin America seems to be one of the main focus of this worldwide “revolution”. However, the high rates of crashes and injuries suffered by commuters have become a relevant issue in the field of road safety, especially in emerging regions with low cycling tradition, where social and infrastructural gaps may endanger the cyclists’ safety. Objectives This study had two objectives. First, to compare key safe cycling-related variables between cycling commuters and non-commuters; and second, to differe…
Disclosure to God as a Mediator Between Private Prayer and Psychological Well-Being in a Christian Sample.
2021
AbstractAlthough a number of studies have reported the psychological and physical benefits of prayer, only a few have examined the means by which prayer affects health. Winkeljohn Black et al. (J Relig Health 54(2):540–553, 2015. 10.1007/s10943-014-9840-4) found disclosure to God as a mediator in the relationship between prayer and mental health. In their study, the authors used Poloma and Pendleton’s (Rev Relig Res 31(1):46–53, 1989. https://doi.org/10.2307/3511023, ) model of prayer. This study examined whether disclosure to God as a mediator can be upheld with Laird et al.’s (Int J Psychol Relig 14(4):251–272, 2004) prayer model. The study included 285 Polish adults (50.2% of women), age…
Changes in Sitting Time, Screen Exposure and Physical Activity during COVID-19 Lockdown in South American Adults: A Cross-Sectional Study
2021
The worldwide prevalence of insufficient physical activity (PA) and prolonged sedentary behavior (SB) were high before the coronavirus (COVID-19) pandemic. Measures that were taken by governments (such as home confinement) to control the spread of COVID-19 may have affected levels of PA and SB. This cross-sectional study among South American adults during the first months of COVID-19 aims to (i) compare sitting time (ST), screen exposure, moderate PA (MPA), vigorous PA (VPA), and moderate-to-vigorous PA (MVPA) before and during lockdown to sociodemographic correlates and (ii) to assess the impact of lockdown on combinations of groups reporting meeting/not-meeting PA recommendations and enga…
The development of African American Vernacular English in two fiction texts: a case study
2009
Afroamerikkalainen englanti on Pohjois-Amerikassa ristiriitaisessa asemassa. Kielitieteilijät eivät ole yhteisymmärryksessä kielen syntyperästä ja näin koko kieli ja sen oikeellisuus on kyseenalaistettu Amerikassa. Kielen käyttäjät ovat useimmiten mustia amerikkalaisia, joista useat ovat joutuneet pilkan kohteiksi puhetyylinsä vuoksi. Nykyään monet mustat jopa pitävät kieltään vain slangina tai muuten virheellisenä. Siksi lisää tutkimuksia afroamerikkalaisesta englannista tarvittaisiin. Tässä tutkimuksessa vertailtiin kahta fiktiivistä afroamerikkalaista tekstiä toisiinsa, jotta nähtiin millaisia eroja ja yhtäläisyyksiä kirjailijoiden kielenkäytössä oli. Näistä eroista tehtiin myös johtopä…
Rasisms un noziegumi Voltera Moslija detektīvromānos "Velns zilā kleitā", "Sarkanā nāve" un "Balts tauriņš"
2019
Bakalauradarbs „Rasisms un kriminālsVolteraMoslijadetektīvromānos „Velnszilākleitā”, „Sarkanānāve” un „Baltstauriņš”” analizēnosauktus romānus ar uzsvaru uz aprakstītas kriminālas situācijas un rasismu ASV kopumā un Kalifornijā. Ņemot vērā ka romāni pieder pie daiļliteratūras un autora situācijas redzējums var atšķirties no reālas situācijas ASV četrdesmitajos un piecdesmitajos gados, ir savākta un apkopota informācija par rasisma un segregācijas vēsturi ASV, lai izprastu, cik patiess priekšstats par situāciju autors dod. Bakalaura darba mērķis ir atrast rasisma un segregācijas piemērus romānos; saprast, kā atrastie piemēri ilustrē rasisma, augstu ieslodzīto un apsūdzēto afroamerikāņu īpats…
Genome-wide association studies identify 137 loci for DNA methylation biomarkers of ageing
2020
AbstractBiological ageing estimators derived from DNA methylation (DNAm) data are heritable and correlate with morbidity and mortality. Leveraging DNAm and SNP data from >41,000 individuals, we identify 137 genome-wide significant loci (113 novel) from meta-analyses of four epigenetic clocks and epigenetic surrogate markers for granulocyte proportions and plasminogen activator inhibitor 1 levels, respectively. We report strong genetic correlations with longevity and lifestyle factors such as smoking, education, and obesity. Significant associations are observed in polygenic risk score analysis and to a lesser extent in Mendelian randomization analyses. This study illuminates the genetic …
Redemption and home in the african american city upon a hill: hannah crafts’s the bondwoman’s narrative.
2019
The Bondwoman’s Narrative (1857) is a novel in which the black female slave Hannah Crafts aims at the remodeling of her society and to gain self–assertion through a deeply Christian commitment and a total and honest respect to the values it impinges drawing broadly on the Bible and reshaping biblical imagery to convey her message and to submit her subjectivity and her Americanness. By using the national continuum of jeremiad rhetoric and her attachment to the values of the Christian creed, the novel partakes and yet takes a different direction from slave narratives by cagily forerunning Du Bois’s praised theory of the double consciousness. In so doing, it positions its protagonist as the fi…
